          CORPORATE BOND-BACKED CERTIFICATES, Series 1997-BellSouth-1
  (UNDERLYING SECURITIES WILL BE 7.12% DEBENTURES DUE JULY 15, 2097 ISSUED BY
                     BELLSOUTH CAPITAL FUNDING CORPORATION)
 

    Each Corporate Bond-Backed Certificate, Series 1997-BellSouth-1 offered
hereby (collectively, the 'Certificates') represents a beneficial interest in a
trust (the 'Trust') formed pursuant to the Trust Agreement dated as of December
16, 1997 between Lehman ABS Corporation (the 'Depositor') and The Bank of New
York, as trustee (the 'Trustee'). The Certificates will be issued in two
classes, Class A-1 and Class A-2, having the characteristics described herein.
 
    The principal assets of the Trust will be $50,000,000 aggregate principal
amount of 7.12% Debentures due July 15, 2097 (the 'Underlying Securities')
issued by BellSouth Capital Funding Corporation (the 'Company' or the
'Underlying Securities Issuer'), having the characteristics described herein
under 'Description of the Underlying Securities.' The Underlying Securities have
the benefit of a Support Agreement dated as of October 15, 1987 and amended as
of August 1, 1992 (the 'Support Agreement'), between the Company and BellSouth
Corporation ('BellSouth' or the 'Underlying Securities Support Provider'), the
parent company and sole shareholder of the Company. In the Support Agreement,
BellSouth has agreed to ensure the timely payment of principal, premium, if any,
and interest owed on the Underlying Securities.
 
    BellSouth Capital Funding Corporation is not participating in, and will not
receive any proceeds in connection with, the offering of the Certificates, and
is not an affiliate of the Depositor or any of its affiliates. The Underlying
Securities were originally issued and sold as part of a public offering in July
1997, were acquired by an affiliate of the Depositor in the secondary market and
will be deposited by the Depositor into the Trust for the benefit of the
Certificateholders.
 
    The holders of the Class A-1 Certificates (the 'Class A-1
Certificateholders') will be entitled to receive, on January 15 and July 15 of
each year (or if such date is not a Business Day (as defined herein), the next
succeeding Business Day) (each a 'Distribution Date'), commencing January 15,
1998 and ending on the Final Scheduled Distribution Date (as defined below), as
and if interest is received on the Underlying Securities, interest distributions
at a rate of 6.50% per annum on the outstanding principal amount of the Class
A-1 Certificates. The Class A-1 Certificates will amortize on each Distribution
Date on a level yield basis. The holders of the Class A-2 Certificates (the
'Class A-2 Certificateholders' and, together with the Class A-1
Certificateholders, the 'Certificateholders') will not be entitled to
distributions of interest. On July 15, 2017 (the 'Final Scheduled Distribution
Date'), the Class A-2 Certificateholders will be entitled to a distribution of

all Underlying Securities held by the Trust as of such date. All distributions
of interest and principal (in the case of the Class A-1 Certificates) or
Underlying Securities (in the case of the Class A-2 Certificates) will be made
on a pro rata basis to the Certificateholders of each respective class. It is a
condition to the issuance of the Certificates that the Certificates have ratings
assigned by Moody's Investors Service, Inc. ('Moody's') and by Standard &
Poor's, 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 'Aa1' by Moody's and 'AAA' by S&P.
 
    The Class A-1 and Class A-2 Certificates have been authorized for listing,
upon official notice of issuance, with the New York Stock Exchange ('NYSE').

                                                 (the 'Specified Currency'). The Class A-1 Certificates will be

CERTAIN FEDERAL INCOME TAX CONSEQUENCES......  In the opinion of tax counsel to the Trust, the Trust will be
                                                 classified for Federal income tax purposes as a grantor trust
                                                 and not as an association (or publicly traded partnership)
                                                 taxable as a corporation. Although it is unclear under the Code
                                                 (as defined in 'Certain Federal Income Tax Consequences--
                                                 General'), the Class A-1 Certificates will be treated by the
                                                 Trust as newly-issued self-amortizing debt obligations maturing
                                                 on the Final Scheduled Distribution Date. Assuming the
                                                 Underlying Securities constitute indebtedness for federal income
                                                 tax purposes, the Class A-2 Certificates will be deemed to be
                                                 issued with original issue discount. See 'Certain Federal Income
                                                 Tax Consequences.'
 
LISTING......................................  The Class A-1 and Class A-2 Certificates have been authorized for
                                                 listing, upon official notice of issuance, with the New York
                                                 Stock Exchange ('NYSE').
 
RATINGS......................................  It is a condition to the issuance of the Certificates that the
                                                 Certificates have ratings assigned by Moody's Investors Service,
                                                 Inc. ('Moody's') and by Standard & Poor's, 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 'Aa1' by Moody's and 'AAA' by S&P.
 
                                               The rating of the Certificates by Moody's addresses the likelihood
                                                 that Certificateholders will receive the timely payment of
                                                 principal and interest on a semi-annual basis beginning January

                                                 distributed in respect of the Class A-2 Certificates. 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 Certificates.
                                                 A security rating is not a recommendation to buy, sell or hold
                                                 securities. The rating on the Certificates does not constitute a
                                                 statement regarding the occurrence or frequency of redemptions
                                                 on, or extensions of the maturity of, the Underlying Securities,
                                                 and the corresponding effect on yield to investors. See

ADVANCE OF MATURITY DATE OR OPTIONAL
  REDEMPTION IN CASE OF TAX EVENT............  BellSouth intends to deduct interest paid on the Underlying
                                                 Securities for federal income tax purposes, and during the past

                                                 several years there have been several legislative proposals
                                                 which, although not enacted, contained 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. Upon the occurrence of a Tax Event (as defined
                                                 below), the Underlying Securities Issuer will have the right to
                                                 shorten the maturity of the Underlying Securities to the minimum
                                                 extent required, such that, after the shortening of the maturity,
                                                 the interest paid on the Underlying Securities will be deductible
                                                 for United States federal income tax purposes.
 
                                               As used herein, 'Tax Event' means that the Underlying Securities
                                                 Issuer shall have received an opinion of a nationally recognized
                                                 independent tax counsel to the effect that, as a result of (a)

                                                 (b) any judicial decision, official administrative pronouncement,
                                                 ruling (including any technical advice memorandum or other

                                                 adopt or promulgate any ruling, regulatory procedure or
                                                 regulation (any of the foregoing, an 'Administrative or Judicial
                                                 Action') or (c) any amendment to, clarification of, or change in

                                                 there is more than an insubstantial increase in the risk that
                                                 interest paid by the Underlying Securities Issuer on the
                                                 Underlying Securities is not, or will not be, deductible, in

                                                 any shortening of the maturity of the Underlying Securities, be
                                                 more than an insubstantial risk that the interest payable by the

Prospectus) in connection with an investment in the Certificates.
 
     Limited Liquidity.  There is currently no secondary market for the
Certificates. Lehman Brothers Inc. is under no obligation to make a market in
the Certificates. It is unlikely that a secondary market will develop and, if a
secondary market does develop, it is unlikely that it will provide
Certificateholders with liquidity of investment or will continue for the life of
the Certificates.
 
     Maturity and Yield Considerations.  The yield realized by a
Certificateholder is dependent upon a number of factors, including, without
limitation, the purchase price of the Certificates, the time of acquisition and
whether a redemption at the option of the Underlying Securities Issuer or a Tax
Event occurs and either (i) the maturity date of the Underlying Securities is
advanced or (ii) the Underlying Securities Issuer exercises its right to redeem
the Underlying Securities. The Depositor has not formulated an opinion as to the
likelihood of a Tax Event. If the Underlying Securities Issuer exercises its
right to redeem Underlying Securities prior to their maturity as a result of a
Tax Event or otherwise, or if the Underlying Securities are paid or sold prior
to maturity as a result of a default, an investment in the Certificates may 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 A-2 Certificates.  Since the Class A-2
Certificates do not receive allocations of either interest or principal until
the Final Distribution Date, the changes in market value of the Class A-2
Certificates as a result of changes in interest rates or spreads are expected to
be more than for the Underlying Securities. The Class A-2 Certificates 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 Certificates, 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 Securities, regardless of adverse
events, financial or otherwise, which may affect the value of the Underlying
Securities or the Underlying Securities Issuer. If there is a payment default on
the Underlying Securities or any other default which may result in an
acceleration of the Underlying Securities, the Trust will only dispose of or
otherwise deal with the defaulted Underlying Securities in the manner provided
in the Trust Agreement.
 
     Credit Risk.  The Certificates represent interests in obligations of a
single obligor. In particular, the Certificates will be subject to all the risks
associated with a direct investment in unsecured debt obligations of BellSouth
Capital Funding Corporation that have the benefit of the Support Agreement (see
'Description of the Underlying Securities--Support Agreement' herein) with
BellSouth Corporation ('BellSouth').
 
     Unsecured Status of Underlying Securities.  The Depositor believes that the
Underlying Securities are general unsecured obligations of the Underlying
Securities Issuer, which should rank on a parity with all other unsecured and
unsubordinated indebtedness of the Underlying Securities Issuer, but which are
subordinate in right of payment to the Underlying Securities Issuer's existing
and future senior secured indebtedness. The benefit of the Support Agreement
with BellSouth is similarly unsecured. To the extent that much of the assets of
BellSouth are the property of its subsidiaries, it should be noted that the
right of creditors of BellSouth (including the holders of the Underlying
Securities) to participate in any distribution of the assets of any subsidiaries
of BellSouth, whether upon liquidation, reorganization, or otherwise, is subject
to prior claims of creditors of the subsidiary, except to the extent that claims
of BellSouth itself as a creditor of a subsidiary may be recognized.
 
     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
Underlying Securities Support Provider, or (ii) verify any reports or
information filed by the Underlying Securities Issuer or Underlying Securities
Support Provider with the SEC. Investors are encouraged to consider publicly
available financial information and other information regarding BellSouth
Capital Funding Corporation and BellSouth Corporation. The issuance of the
Certificates should not be construed as an endorsement by the

 
                                      S-12
<PAGE>
Depositor, the Underwriter or the Trustee of the financial condition or business
prospects of BellSouth Capital Funding Corporation and BellSouth Corporation.
 
     Ratings of the Certificates.  At the time of issuance, the Certificates
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
'Aa1' by Moody's and 'AAA' by S&P. It is expected that the ratings of the
Certificates will change if the ratings of the Underlying Securities change.
 
     Any rating issued with respect to the Certificates is not a recommendation
to purchase, sell or hold a security inasmuch as such ratings do not comment on
the market price of the Certificates 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
Certificates.
 
                                   THE TRUST
 
     The Trust will be formed pursuant to the Series Supplement, Series
1997-BellSouth-1 (the 'Series Supplement'), which incorporates the Standard
Terms for Trust Agreements (the 'Standard Terms' and, together with the Series
Supplement, the 'Trust Agreement') by and between the Depositor and the Trustee.
Concurrently with the execution and delivery of the Series 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
Certificates to or upon the order of the Depositor.
 
     The Underlying Securities were purchased by an affiliate of the Depositor
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 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 Certificates. Lehman Brothers Inc., an affiliate of the
Depositor, participated in the public offering of the Underlying Securities in
July 1997.
 
                    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 Certificates. The aggregate
principal balance of the Underlying Securities is $50,000,000. The primary
economic terms of the Underlying Securities are described in '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, the Underlying Securities Issuer or the
Underlying Securities Support Provider. This Prospectus Supplement relates only
to the Certificates 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 and the Underlying Securities Support
Provider are not participating in, and will not receive any proceeds in
connection with, the offering of the Certificates. The Underlying Securities
were purchased by an affiliate of the Depositor 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 the publicly available documents of BellSouth Capital Funding
Corporation (the 'Company' or the 'Underlying Securities Issuer'), its principal
executive offices are located at 1155 Peachtree Street, N.E., Atlanta, Georgia
30309-3610 and its telephone number is (404) 249-2000. The Company is a
wholly-owned subsidiary of BellSouth Corporation ('BellSouth' or the 'Underlying
Securities Support Provider'). The Company's purpose is engaging in financing
activities that will provide funds for use by BellSouth in connection
 
                                      S-13
<PAGE>
with its own diversification and in support of the activities of the
subsidiaries of BellSouth ('Diversified Subsidiaries') other than BellSouth
Telecommunications, Inc. (the 'Telephone Company') but including such
subsidiaries of the Telephone Company whose operations are not subject to
regulation by tariff. The Company raises funds through the offering and sale of
debt securities (the ' Debt Securities') and lends the proceeds to BellSouth or
the Diversified Subsidiaries. The Company does not engage in any separate
business operations. On October 14, 1987, the Securities and Exchange Commission
(the 'SEC') issued an order exempting the Company from the provisions of the
Investment Company Act of 1940 (the '1940 Act'), provided that the Company
complies with the provisions of the 1940 Act and that the Debt Securities remain
entitled to the benefits of the Support Agreement (as defined below). The
Company is not subject to the informational requirements of the SEC, and no
documents have been or will be filed by the Company under the Securities
Exchange Act of 1934, as amended (the 'Exchange Act'). BellSouth's principal
executive offices are located at 1155 Peachtree Street, N.E., Atlanta, Georgia
30309-3610 and its telephone number is (404) 249-2000. BellSouth is subject to
the informational requirements of the Exchange Act, and, in accordance therewith
files reports and other information with the SEC. Such reports and other
information may be inspected and copied at the public reference facilities
maintained by the SEC at 450 Fifth Street, N.W., Washington, D.C. 20549, and at
the following Regional Offices of the SEC: New York Regional Office, Room 1102,
13th Floor, 7 World Trade Center, New York, New York 10048 and Chicago Regional
Office, Suite 1400, Northwestern Atrium Center, 500 West Madison Street,
Chicago, Illinois 60661-2511, and copies of such material can be obtained from
the Public Reference Section of the SEC, Washington, D.C. 20549, at prescribed
rates. Such reports and other information may also be inspected at the New York,
Boston, Midwest, Pacific and Philadelphia Stock Exchanges. Copies of the above

documents which have been electronically filed through the Electronic Data
Gathering, Analysis and Retrieval system ('EDGAR') are publicly available
through the SEC's website (http://www.sec.goc).
 
     Although the Depositor has no reason to believe the information concerning
the Underlying Securities, the Underlying Securities Issuer, or the Underlying
Securities Support Provider 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, the Underlying Securities Support Provider
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 SIGNIFICANT ASSETS OTHER THAN THE UNDERLYING
SECURITIES FROM WHICH TO MAKE DISTRIBUTIONS OF AMOUNTS DUE IN RESPECT OF THE
CERTIFICATES. CONSEQUENTLY, THE ABILITY OF CERTIFICATEHOLDERS TO RECEIVE
DISTRIBUTIONS IN RESPECT OF THE CERTIFICATES WILL DEPEND ENTIRELY ON THE TRUST'S
RECEIPT OF PAYMENTS ON THE UNDERLYING SECURITIES. PROSPECTIVE PURCHASERS OF THE
CERTIFICATES SHOULD CONSIDER CAREFULLY THE FINANCIAL CONDITION OF THE UNDERLYING
SECURITIES ISSUER AND THE UNDERLYING SECURITIES SUPPORT PROVIDER AND THEIR
ABILITY TO MAKE PAYMENTS IN RESPECT OF SUCH UNDERLYING SECURITIES. THIS
PROSPECTUS SUPPLEMENT RELATES ONLY TO THE CERTIFICATES BEING OFFERED HEREBY AND
DOES NOT RELATE TO THE UNDERLYING SECURITIES, THE UNDERLYING SECURITIES SUPPORT
PROVIDER OR THE UNDERLYING SECURITIES ISSUER. ALL INFORMATION CONTAINED IN THIS
PROSPECTUS SUPPLEMENT REGARDING THE UNDERLYING SECURITIES ISSUER, THE UNDERLYING
SECURITIES SUPPORT PROVIDER AND THE UNDERLYING SECURITIES IS DERIVED FROM
PUBLICLY AVAILABLE DOCUMENTS. NEITHER THE DEPOSITOR NOR THE TRUSTEE PARTICIPATED
IN THE PREPARATION OF SUCH DOCUMENTS OR TAKES ANY RESPONSIBILITY FOR THE
ACCURACY OR COMPLETENESS OF THE INFORMATION PROVIDED THEREIN.
 
INDENTURE
 
     The Underlying Securities were issued under an Indenture dated as of August
1, 1992 (the 'Indenture') among BellSouth, the Underlying Securities Issuer and
The Bank of New York, as successor to Wachovia Bank of Georgia, N.A. (the
'Underlying Securities Trustee') providing for the issuance of debt securities
by the Underlying Securities Issuer (the 'Debt Securities'). The Underlying
Securities were part of an issue totalling $500,000,000. The following summaries
of certain provisions of the Debt Securities and the Indenture do not purport to
be complete and are based upon the Prospectus dated July 22, 1997, and the
Prospectus Supplement dated July 22, 1997 (together, the 'Prospectus for the
Underlying Securities'), relating to Debt Securities, of which the Underlying
Securities are part of a series, of the Underlying Securities Issuer, and are
subject to, and are qualified in their entirety by reference to, all provisions
of the Underlying Securities and the Indenture,
 
                                      S-14
<PAGE>
including the definitions therein of certain terms. Wherever particular sections
or defined terms of the Indenture are referred to, it is intended that such
sections or defined terms shall be incorporated herein by reference.
 

     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, by a Company Order signed by two Officers of the Underlying
Securities Issuer 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.
 
SUPPORT AGREEMENT
 
     All of the Underlying Securities have the benefit of a Support Agreement
dated as of October 15, 1987, as amended as of August 1, 1992 (the 'Support
Agreement'), between the Company and BellSouth, the parent company and sole
shareholder of the Company. In the Support Agreement, BellSouth has agreed to
ensure the timely payment of principal, premium, if any, and interest owed on
the Underlying Securities; however, no holder of the Underlying Securities will
have recourse to or against the stock or assets of the Telephone Company or any
interest of BellSouth or the Company in the Telephone Company.
 
     Pursuant to the Support Agreement, BellSouth has agreed to cause the
Company to maintain a positive tangible net worth as determined in accordance
with generally accepted accounting principles. The Support Agreement also
provides that BellSouth shall own, directly or indirectly, all the outstanding
voting capital stock of the Company throughout the term of the Support
Agreement.
 
     If the Company is unable to pay when due the principal, interest or
premium, if any, owed on any of the Underlying Securities, BellSouth shall
provide funds to the Company to assure that the Company will be able to pay when
due such principal, interest or premium, if any. The Support Agreement provides
that in the event of any default by BellSouth in meeting its obligations under
such Support Agreement or in the event of default by the Company in the timely
payment of principal, interest or premium, if any, owed on any Underlying
Securities, holders of Underlying Securities or a trustee acting on their behalf
shall be entitled to proceed directly against BellSouth, except that no holder
of Underlying Securities or trustee acting on their behalf will have recourse to
or against the stock or assets of the Telephone Company or any interest of
BellSouth or the Company in the Telephone Company. Dividends declared and paid
to BellSouth by the Telephone Company are not subject to this limitation.
 
     Neither BellSouth nor the Company will be able to amend or terminate the
Support Agreement so as to adversely affect the rights of holders of Underlying
Securities without the written consent of all the holders of the then
outstanding Debt Securities maturing in more than one year. The holders of
Underlying Securities maturing in less than one year shall have the benefit of
the Support Agreement without giving effect to any such amendment or termination
until the Underlying Securities held by them have been retired.
 
LIENS ON ASSETS
 
     If at any time, the Underlying Securities Issuer mortgages, pledges, or

otherwise subjects to any lien the whole or any part of any property or assets
now owned or hereafter acquired by it, except as hereinafter provided, the
Underlying Securities Issuer will secure the outstanding Underlying Securities,
and any other obligations of the Underlying Securities Issuer which may then be
outstanding and entitled to the benefit of a covenant similar in effect to this
covenant, equally and ratably with the indebtedness or obligations secured by
such mortgage, pledge, or lien, for as long as any such indebtedness or
obligation is so secured. The foregoing covenant does not apply to the creation,
extension, renewal or refunding of purchase-money mortgages or liens, or to the
making of any deposit or pledge to obtain the benefits of any law relating to
workers' compensation, unemployment insurance, old age pensions, or other social
security, or with any court, board, commission or governmental agency as
security incident to the proper conduct of any proceeding before it. However,
nothing contained in the Indenture or the Support Agreement restricts the
Underlying Securities Support Provider from pledging or otherwise encumbering
any of its assets.
 
                                      S-15
<PAGE>
AMENDMENT AND WAIVER
 
     Subject to certain exceptions, the Indenture and the Debt Securities may be
amended or supplemented by the Underlying Securities Issuer, the Underlying
Securities Support Provider, and the Underlying Securities Trustee with the
consent of the holders of a majority in principal amount of the outstanding
Underlying Securities and the other Debt Securities that comprise each series
affected by the amendment or supplement, and compliance with any provision may
be waived with the consent of holders of a majority in principal amount of the
outstanding Debt Securities of each series affected by such waiver. However,
without the consent of each Debt Securityholder affected, an amendment or waiver
may not (i) reduce the amount of Debt Securities whose holders must consent to
an amendment or waiver; (ii) reduce the rate of or change the time for payment
of interest on any Debt Security; (iii) reduce the principal of, or change the
fixed maturity of, any Debt Security; (iv) waive a default in the payment of the
principal of or interest on any Debt Security; (v) make any Debt Security
payable in money other than that stated in the Debt Security; (vi) impair the
right to institute suit for the enforcement of any payment on or with respect to
any Debt Securities; or (vii) amend or terminate the Support Agreement to the
detriment of the Debt Securityholders. The Indenture may be amended or
supplemented without the consent of any Debt Securityholder (i) to cure any
ambiguity, defect, or inconsistency in the Indenture or in the Debt Securities
of any series; (ii) to secure the Debt Securities under the circumstances set
forth under the section 'Lien on Assets' above; (iii) to provide for the
assumption of all the obligations of the Underlying Securities Issuer or the
Underlying Securities Support Provider, as the case may be, under the Debt
Securities and any coupons related thereto and the Indenture in connection with
a merger, consolidation or transfer or lease of the Underlying Securities
Issuer's or the Underlying Securities Support Provider's property and assets
substantially as an entirety as provided for in the Indenture; (iv) to provide
for the assumption by the Underlying Securities Support Provider or a subsidiary
thereof of all obligations of the Underlying Securities Issuer under the Debt
Securities and any coupons related thereto and the Indenture; (v) to provide for
the issuance of, and establish the form, terms and conditions of, a series of
Debt Securities or to establish the form of any certifications required to be

furnished pursuant to the terms of the Indenture or any series of Debt
Securities; (vi) to provide for uncertificated Debt Securities in addition to or
in place of certificated Debt Securities; (vii) to add to rights of Debt
Securityholders or surrender any right or power conferred on the Underlying
Securities Issuer; or (viii) to make any change that does not adversely affect
the rights of any Debt Securityholder.
 
MERGER
 
     Neither the Underlying Securities Issuer nor the Underlying Securities
Support Provider may consolidate with or merge into, or transfer or lease its
property and assets substantially as an entirety to, another entity unless the
successor entity is a United States corporation and, in the case of the
Underlying Securities Issuer, assumes all the obligations of the Underlying
Securities Issuer under the Underlying Securities and any coupons related
thereto and the Indenture and, in the case of the Underlying Securities Support
Provider, assumes all the obligations of the Underlying Securities Support
Provider under the Indenture and the Support Agreement. Thereafter, except in
the case of a lease, all such obligations of the Underlying Securities Issuer or
the Underlying Securities Support Provider, as the case may be, shall terminate.
 
     The Underlying Securities Support Provider or a subsidiary thereof may
assume the payment of the principal of and interest on all Underlying Securities
and any coupons and the performance of every covenant of the Indenture on the
part of the Underlying Securities Issuer. Upon such assumption, the Underlying
Securities Support Provider or such subsidiary shall have the same rights and
obligations as the Underlying Securities Issuer under the Indenture, and the
Underlying Securities Issuer shall be released from its liability thereunder.
 
EVENTS OF DEFAULT
 
     The following events are defined in the Indenture as 'Events of Default'
with respect to a series of Debt Securities: (i) default in the payment of
interest on any Debt Security of such series for 90 days; (ii) default in the
payment of the principal of any Debt Security of such series; (iii) failure by
the Underlying Securities Issuer or the Underlying Securities Support Provider
for 90 days after notice to it to comply with any of its other agreements with
respect to the Debt Securities of such series set forth in the Indenture in any
supplemental indenture under which the Debt Securities of that series may have
been issued (other than covenants relating only to other series) or in the
Support Agreement; and (iv) certain events of bankruptcy or insolvency of the
 
                                      S-16
<PAGE>
Underlying Securities Issuer. A payment default with respect to one series is
not a default with regard to any other series of Debt Securities issued pursuant
to the Indenture. If an Event of Default occurs with respect to the Debt
Securities of any series, and is continuing, the Underlying Securities Trustee
or the holders of at least 25% in principal amount of all of the outstanding
Debt Securities of that series may declare the principal of, and any accrued
interest on, all the Underlying Securities and other Debt Securities of that
series to be due and payable. The Prospectus for the Underlying Securities
states that upon such declaration, such principal and interest shall become due
and payable immediately.

 
     Securityholders may not enforce the Indenture, the Debt Securities or the
Support Agreement, except as provided in the Indenture and the Support
Agreement. The Underlying Securities Trustee may require indemnity satisfactory
to it before it enforces the Indenture, the Debt Securities or the Support
Agreement. Subject to certain limitations, holders of a majority in principal
amount of the Debt Securities of each series affected may direct the Underlying
Securities Trustee in its exercise of any trust power with respect to Debt
Securities of that series. The Underlying Securities Trustee may withhold from
Underlying Securityholders notice of any continuing default (except a default in
payment of principal or interest) if it determines that withholding notice is in
their interests.
 
REDEMPTION AT THE OPTION OF THE UNDERLYING SECURITIES ISSUER
 
     The Underlying Securities are redeemable as a whole at any time or in part
from time to time, at the option of the Underlying Securities Issuer, on not
less than 30 nor more than 60 days' notice mailed to holders thereof, at a
redemption price equal to the greater of (i) 100% of the principal amount of the
Underlying Securities to be redeemed and (ii) the sum of the present values of
the Remaining Scheduled Payments (as defined below) thereon discounted to the
redemption date on a semiannual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Treasury Rate (as defined below) plus 15 basis
points, together, in either case, with accrued interest on the principal amount
being redeemed to the date of such redemption.
 
     In addition, if a Tax Event occurs and in the opinion of nationally
recognized independent tax counsel, there would, notwithstanding any shortening
of the maturity of the Underlying Securities, be more than an insubstantial risk
that interest paid by the Underlying Securities Issuer on the Underlying
Securities is not, or will not be, deductible, in whole or in part, by the
Underlying Securities Support Provider for United States federal income tax
purposes, the Underlying Securities Issuer will have the right, within 90 days
following the occurrence of such Tax Event, to redeem the Underlying Securities
in whole (but not in part), on not less than 30 nor more than 60 days' notice
mailed to holders of the Underlying Securities, at a redemption price equal to
the greater of (i) 100% of the principal amount of the Underlying Securities and
(ii) the sum of the present values of the Remaining Scheduled Payments thereon
discounted to the redemption date on a semiannual basis (assuming a 360-day year
consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points,
together, in either case, with accrued interest on the principal amount being
redeemed to the date of redemption.
 
     'Treasury Rate' means, with respect to any redemption date, the rate per
annum equal to the semiannual equivalent yield to maturity (computed as of the
second business day immediately preceding such redemption date) of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such redemption date.
 
     'Comparable Treasury Issue' means the United States Treasury security
selected by an Independent Investment Banker that would be utilized, at the time
of selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of comparable maturity to the remaining term

of the Underlying Securities. 'Independent Investment Banker' means one of the
Reference Treasury Dealers appointed by the Underlying Securities Issuer.
 
     'Comparable Treasury Price' means, with respect to any redemption date, (i)
the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
business day preceding such redemption date, as set forth in the daily
statistical release (or any successor release) published by the Federal Reserve
Bank of New York and designated 'Composite 3:30 p.m. Quotations for U.S.
Government Securities' or (ii) if such release (or any successor release) is not
published or does not contain such prices on such business day, (A) the average
of the Reference Treasury Dealer Quotations for such redemption date, after
excluding the highest and lowest of such Reference Treasury Dealer Quotations,
or (B) if the Underlying Securities Trustee obtains fewer than four such
Reference Treasury Dealer Quotations,
 
                                      S-17
<PAGE>
the average of all such quotations. 'Reference Treasury Dealer Quotations'
means, with respect to each Reference Treasury Dealer and any redemption date,
the average, as determined by the Underlying Securities Trustee, of the bid and
asked prices for the Comparable Treasury Issue (expressed in each case as a
percentage of its principal amount) quoted in writing to the Underlying
Securities Trustee by such Reference Treasury Dealer as of 3:30 p.m., New York
time, on the third business day preceding such redemption date.
 
     'Reference Treasury Dealer' means each of Morgan Stanley & Co.
Incorporated, Bear, Stearns & Co. Inc., Goldman, Sachs & Co., Lehman Brothers
Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, and J.P. Morgan
Securities Inc. and their respective successors; provided, however, that if any
of the foregoing shall cease to be a primary U.S. Government securities dealer
in New York City (a 'Primary Treasury Dealer'), the Underlying Securities Issuer
shall substitute therefor another nationally recognized investment banking firm
that is a Primary Treasury Dealer.
 
     'Remaining Scheduled Payments' means, with respect to each Underlying
Security to be redeemed, the remaining scheduled payments of the principal
thereof and interest thereon that would be due after the related redemption date
but for such redemption; provided, however, that, if such redemption date is not
an interest payment date with respect to such Underlying Security, the amount of
the next succeeding scheduled interest payment thereon will be reduced by the
amount of interest accrued thereon to such redemption date.
 
     On and after any redemption date, interest will cease to accrue on the
Underlying Securities or any portion thereof called for redemption. On or before
any redemption date, the Underlying Securities Issuer shall deposit with a
paying agent (or the Underlying Securities Trustee) money sufficient to pay the
redemption price of and accrued interest on the Underlying Securities to be
redeemed on such date. If less than all the Underlying Securities are to be
redeemed, the Underlying Securities to be redeemed shall be selected by the
Underlying Securities Trustee by such method as the Underlying Securities
Trustee shall deem fair and appropriate.
 
ADVANCE OF MATURITY DATE OR OPTIONAL REDEMPTION IN CASE OF TAX EVENT

 
     The Underlying Securities Support Provider states in the Prospectus for the
Underlying Securities that it intends to deduct interest paid on the Underlying
Securities for United States federal income tax purposes. However, during the
past several years there have been several legislative proposals which, although
not enacted, contained 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.
 
     Upon the occurrence of a Tax Event (as defined below), the Underlying
Securities Issuer will have the right to shorten the maturity of the Underlying
Securities to the minimum extent required, in the opinion of a nationally
recognized independent tax counsel, such that, after the shortening of the
maturity, interest paid on the Underlying Securities will be deductible for
United States federal income tax purposes or, if such counsel is unable to opine
definitively as to such a minimum period, the minimum extent so required as
determined in good faith by the Board of Directors of the Underlying Securities
Issuer, after receipt of an opinion of such counsel regarding the applicable
legal standards. There can be no assurance that the Underlying Securities Issuer
would not exercise its right to shorten the maturity of the Underlying
Securities upon the occurrence of such a Tax Event or as to the period by which
such maturity would be shortened. In the event that the Underlying Securities
Issuer elects to exercise its right to shorten the maturity of the Underlying
Securities on the occurrence of a Tax Event, the Underlying Securities Issuer
will mail a notice of shortened maturity to each holder of the Underlying
Securities by first-class mail not more than 60 days after the occurrence of
such Tax Event, stating the new maturity date of the Underlying Securities. Such
notice shall be effective immediately upon mailing.
 
     The Underlying Securities Issuer states in the Prospectus for the
Underlying Securities that it believes that the Underlying Securities should
constitute indebtedness for United States federal income tax purposes under
current law and that, in that case, an exercise of its right to shorten the
maturity of the Underlying Securities would not be a taxable event to beneficial
owners of Underlying Securities for such purposes. However the Underlying
Securities Issuer's exercise of its right to shorten the maturity of the
Underlying Securities will be a taxable event for United States federal income
tax purposes to beneficial owners of Underlying Securities if the Underlying
Securities are treated as equity for such purposes before the maturity is
shortened, assuming that the Underlying Securities of shortened maturity are
treated as debt for such purposes.

     'Tax Event' means that the Underlying Securities Issuer shall have received
an opinion of a nationally recognized independent tax counsel to the effect
that, as a result of (a) any amendment to, clarification of or change (including
any announced prospective amendment, clarification or change) in any law, or any
regulation thereunder, of the United States, (b) any judicial decision, official
administrative pronouncement, ruling (including any technical advice memorandum
or other private letter ruling), regulatory procedure, notice or announcement,
including any notice or announcement of intent to adopt or promulgate any
ruling, regulatory procedure or regulation (any of the foregoing, an
'Administrative or Judicial Action') or (c) any amendment to, clarification of,

or change in any official position with respect to, or any interpretation of
(including any position taken in any Internal Revenue Service audit or similar
proceeding), an Administrative or Judicial Action or a law or regulation of the
United States that differs from the theretofore generally accepted position or
interpretation, in each case, occurring on or after July 22, 1997, there is more
than an insubstantial increase in the risk that interest paid by the Underlying
Securities Issuer on the Underlying Securities is not, or will not be,
deductible, in whole or in part, by the Underlying Securities Support Provider
for United States federal income tax purposes.
 
     In addition, the Indenture provides for the optional redemption of the
Underlying Securities by the Underlying Securities Issuer. See 'Description of
the Underlying Securities--Redemption at the Option of the Underlying Securities
Issuer.'
 
CONCERNING THE UNDERLYING SECURITIES TRUSTEE
 
     The Underlying Securities Support Provider and certain of its affiliates
maintain banking relationships in the ordinary course of business with the
Underlying Securities Trustee 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, the
Depository Trust Company, as depositary (the 'Depositary' or '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 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 or its nominee ('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 or
its nominee (with respect to interests of participants) and on the records of
participants (with respect to interests of persons other than participants). The
laws of some states require that certain purchasers of securities take physical
delivery of such securities in definitive form. Such limits and such laws may
impair the ability to 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, the 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 and interest payments on
Underlying Securities registered in the name of the 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.
None of the Underlying Securities Issuer, the Underlying Securities Trustee, any
paying agent or the 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.
 
                                      S-19
<PAGE>
     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 CERTIFICATES
 
GENERAL
 
     The Certificates will be denominated and distributions with respect thereto
will be payable in U.S. dollars (the 'Specified Currency'). The Class A-1
Certificates have an aggregate initial Certificate Principal Amount of
$39,464,386. The Class A-2 Certificates have an aggregate Certificate Principal
Amount of $50,000,000.
 
THE CLASS A-1 CERTIFICATES
 
     The aggregate 'Certificate Principal Amount' of the Class A-1 Certificates
will initially be $39,464,386. On any Distribution Date, the aggregate
Certificate Principal Amount of the Class A-1 Certificates will be reduced by
the positive difference between (i) the semiannual fixed payment made on such
Distribution Date and (ii) interest accrued on the aggregate Certificate
Principal Amount at an annual rate of 6.50% compounded semiannually from the
prior Distribution Date (or, in the case of the initial Distribution Date, such
interest accrued from the Closing Date). The Certificate Principal Amount of any
Class A-1 Certificate will represent a pro rata portion of the then-current
aggregate Certificate Principal Amount of all outstanding Class A-1
Certificates. See Schedule A below for the amortization schedule of the Class
A-1 Certificates.
 
     The Class A-1 Certificateholders will be entitled to receive, on January 15
and July 15 of each year (or if such date is not a Business Day, the next
succeeding Business Day) (each, a 'Distribution Date'), commencing January 15,
1998 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 A-1 Certificates in accordance with Schedule A, the
amortization schedule set forth below, and the payment of interest at a rate of
6.50% per annum on the outstanding principal amount of the Class A-1

Certificates. The Class A-1 Certificates will amortize on each Distribution Date
on a level yield basis. The Class A-1 Certificateholders generally will not be
entitled to any allocation of any principal payments received on the Underlying
Securities.
 
     Interest on the Class A-1 Certificates will be calculated on a 30/360 basis
and will accrue from and including the prior Distribution Date (or, in the case
of the first interest accrual period, from and including the Closing Date) to
but excluding the current Distribution Date.
 
THE CLASS A-2 CERTIFICATES
 
     The aggregate 'Certificate Principal Amount' of the Class A-2 Certificates
on any determination date will equal the aggregate principal amount of the
Underlying Securities in the Trust as of such date. The Certificate Principal
Amount of any Class A-2 Certificate will represent a pro rata portion of the
then-current aggregate Certificate Principal Amount of all outstanding Class A-2
Certificates and will equal the principal amount of Underlying Securities that
the holder of such Class A-2 Certificate is entitled to receive as an in-kind
distribution on July 15, 2017. The Class A-2 Certificates will be issued with an
aggregate Certificate Principal Amount of $50,000,000 and will not be entitled
to distributions of interest. Subject to the occurrence of a Redemption at the
Option of the Underlying Securities Issuer or an Advance of Maturity Date or
Optional Redemption in Case of Tax Event, and subject to the occurence of
certain defaults on the Underlying Securities, no cash distributions will be
made to the Class A-2 Certificateholders. Instead, on July 15, 2017, the holders
of the Class A-2 Certificates outstanding 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 July 15, 2017, the Trustee shall request instructions
from the registered Class A-2 Certificateholders regarding the account or
accounts to which transfer of the Underlying Securities should be made, and
other information relevant to such transfer.

REGISTRATION AND DENOMINATIONS
 
     The Certificates will be delivered in registered form. The Certificates
will be issued, maintained and transferred on the book-entry records of DTC and
its Participants in minimum principal amounts of $100,000 and integral multiples
of $1,000 in excess thereof in the case of both the Class A-1 Certificates and
Class A-2 Certificates. One Certificate of each class may be issued in an amount
other than an integral multiple of the applicable minimum denomination. Each
class of Certificates will each initially be represented by one or more global
certificiates 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 & Co. ('CEDE'). No holder of any such Certificate will be
entitled to receive a certificate representing such person's interest, except as

set forth below under '--Definitive Certificates.' Unless and until Definitive
Certificates are issued under the limited circumstances described herein, all
references to actions by Certificateholders with respect to any such
Certificates shall refer to actions taken by DTC upon instructions from its
Participants. See '--Definitive Certificates' below and 'Description of
Certificates--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
Certificateholder under the Trust Agreement only at the direction of one or more
Participants to whose DTC account such Certificates 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
Certificates evidences such voting rights, authorize divergent action.
 
DEFINITIVE CERTIFICATES
 
     Definitive Certificates will be issued to Certificateholders 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 Certificates 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 Certificates. Upon surrender by DTC of
the definitive certificates representing the Certificates and receipt of
instructions for re-registration, the Trustee will reissue such Certificates as
Definitive Certificates issued in the respective principal amounts owned by the
individual owners of such Certificates, and thereafter the Trustee will
recognize the holders of such Definitive Certificates as Certificateholders
under the Trust Agreement.
 
LISTING ON THE NEW YORK STOCK EXCHANGE
 
     The Class A-1 and Class A-2 Certificates have been authorized for listing,
upon official notice of issuance, with the NYSE. There can be no assurance that
the Certificates, once listed, will continue to be eligible for trading on the
NYSE.
 
COLLECTIONS AND DISTRIBUTIONS
 
     Except as otherwise provided herein (see 'Default on Underlying Securities'
and 'Distributions upon Optional Redemption or Advance of Maturity Date'),
collections on the Underlying Securities that are received by the Trustee for a
given Collection Period pursuant to the collection procedures described herein
and in the Prospectus and deposited from time to time into the Certificate
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 incurred by the Trustee in accordance with the
         Trust Agreement pursuant to instructions of not less than 100% of the
         Certificateholders;
 
     (b) to the holders of the Class A-1 Certificates, interest at the rate of
         6.50% per annum on the principal amount of the Class A-1 Certificates
         and principal distributable on such Class A-1 Certificates on such
         Distribution Date; and
 
                                      S-22
<PAGE>
     (c) to the holders of the Class A-2 Certificates, 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.
 
     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
Certificates or be owed to Certificateholders 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 A-1
Certificateholders. In the event of a 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 Certificateholders are made.
 
     All amounts received on or with respect to the Underlying Securities, which
are not distributed to Certificateholders 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 Certificates, 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 Certificates, 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 Certificateholders. To the extent Available Funds are
insufficient to make any such distributions due to any Class of Certificate, any
shortfall will be carried over and will be distributable on the next
Distribution Date on which sufficient funds exist to pay such shortfalls.
 
EXCHANGE OF CERTIFICATES
 
     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 its holds Class A-2 Certificates of a certain principal amount
and Class A-1 Certificates 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 Certificates 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 or other applicable
exemption 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 principal amount of the Class A-2
Certificates being tendered to such Certificateholder. The right of the
Depositor or any affiliate to effect any such exchange is subject to substantial
restrictions as to timing, amount and other matters, as set forth in the Trust
Agreement.
 
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 in
connection with a default thereon, the Trustee will distribute the Underlying
Securities to the Certificateholders in accordance with the Allocation Ratio
within 30 days of the occurrence of such default. If, as a result of the minimum
denominations of the Underlying Securities, the Trustee cannot distribute the
Underlying Securities to the Certificateholders in accordance with the
Allocation Ratio, the Trustee will be permitted to sell, in accordance with the
Sales Procedures (as defined in 'The Market Agent Agreement--Sale of the
Underlying Securities'), such amount of the Underlying Securities as will be
necessary in order that the Underlying Securities, together with the proceeds
received from the sale of any portion thereof, may be distributed in accordance
with the Allocation Ratio.
 
     As used herein, 'Allocation Ratio' means the ratio of the Class A-1
Allocation to the Class A-2 Allocation. The 'Class A-1 Allocation' means the
present value (discounted at the rate of 6.892% per annum) 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 A-2 Allocation' means the
sum of the present values (discounted at the rate of 6.892% per annum) of (i)
the unpaid interest coupons due or to become due on the Underlying Securities
after the Final Scheduled Distribution Date and (ii) the principal amount of the
Underlying Securities (in each case
 
                                      S-23
<PAGE>
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 DATE
 
     In the event of an optional redemption of the Underlying Securities or an
early payment as a result of an advance of the maturity date of the Underlying
Securities to a date prior to the Final Scheduled Distribution Date 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' and 'Description of the Underlying Securities--Redemption at the Option
of the Underlying Securities Issuer' herein), the proceeds of such redemption or
early payment will be allocated between the Class A-1 Certificateholders and the
Class A-2 Certificateholders in accordance with the Allocation Ratio. Schedule
B, which shows the percentages of such payment that would be distributable to
the Class A-1 and Class A-2 Certificateholders, respectively, if the redemption
occurred on any semiannual Distribution Date on or prior to July 15, 2017, is
set forth below.

                                 THE DEPOSITOR
 
     Lehman ABS Corporation (the 'Depositor') was incorporated in the State of
Delaware on January 29, 1988. The Depositor is a wholly owned, special purpose
subsidiary of Lehman Commercial Paper Inc. ('LCPI'), which is itself a wholly
owned subsidiary of Lehman Brothers Inc. ('Lehman Brothers'), which is a wholly
owned subsidiary of Lehman Brothers Holdings Inc. ('Holdings'). None of Lehman
Brothers, LCPI, Holdings or the Depositor, nor any affiliate of the foregoing,
has guaranteed or is otherwise obligated with respect to the Certificates.
 
     The principal executive offices of the Depositor are located at Three World
Financial Center, New York, New York 10285 (Telephone: (212) 526-4428). See 'The
Depositor' in the Prospectus.
 
                       DESCRIPTION OF THE TRUST AGREEMENT
 
GENERAL
 
     The Certificates 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 Certificates 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 Certificates. The Trust created under the Trust
Agreement (including the Series 1997-BellSouth-1 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
Certificates. 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 Certificates.
 
THE TRUSTEE
 
     The Bank of New York, a New York banking corporation, will act as trustee

(the 'Trustee') for the Certificates and the Trust pursuant to the Trust
Agreement. The Trustee's offices are located at 101 Barclay Street, New York,
New York 10286 and its telephone number is (212) 815-5098.
 
     Pursuant to the Trust Agreement, the Trustee shall receive compensation at
the rate set forth in the Trust Agreement payable from Available Funds on each
Distribution Date (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 that would be payable out of the Trust property, unless (i) the Trustee
is satisfied that it will have adequate security or indemnity in respect of such
costs, expenses and liabilities and (ii) the Trustee has been instructed to do
so by Certificateholders representing not less than 100% of the aggregate voting
rights of each class of Certificates then outstanding. Extraordinary Expenses so
incurred may be reimbursed to the Trustee out of Available Funds on any
Distribution Date before any distributions to Certificateholders 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 Certificateholder, 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
 
                                      S-25
<PAGE>
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 Certificates 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 30 days after the occurrence
of an Event of Default in respect of the Certificates, the Trustee will give

notice to the Certificateholders, 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 of 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 Certificateholders.
 
     No Certificateholder will have the right to institute any proceeding with
respect to the Trust Agreement, unless (i) such Certificateholder previously has
given to the Trustee written notice of a continuing breach, (ii)
Certificateholders 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 Certificateholder or
Certificateholders 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 Certificateholders evidencing not less than the Required
Percentage--Remedies of the aggregate Voting Rights. 'Required
Percentage--Remedies' shall mean 66 2/3% of the Voting Rights.
 
VOTING RIGHTS
 
     At all times, 100% of all Voting Rights will be allocated between the Class
A-1 Certificates and the Class A-2 Certificates in accordance with the
Allocation Ratio. Within each such class, Voting Rights shall be allocated among
Certificateholders in proportion to the then outstanding principal amounts of
their respective Certificates. The 'Required Percentage--Amendment' of Voting
Rights necessary to consent to such modification or amendment shall be 66 2/3%.
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 Certificates without the
consent of the holders of 100% of such class of Certificates; 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 which would adversely affect in any
material respect the interests of Certificateholders 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 Certificates.
 
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
Certificateholder of record as of such date. The Trustee shall request
instructions from the Certificateholders as to whether or not to consent to or

vote to accept such
 
                                      S-26
<PAGE>
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 amounts of the Certificates) as the Certificates
of the Trust were actually voted or not voted by the Certificateholders thereof
as of a date determined by the Trustee prior to the date on which such consent
or vote is required, after weighting the votes of the Class A-1
Certificateholders and the votes of the Class A-2 Certificateholders 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 A-1 and Class A-2 Certificateholders, 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 Certificateholders representing 100% of the outstanding Class A-1
and Class A-2 Certificates. The Trustee shall have no liability for any failure
to act resulting from Certificateholders' late return of, or failure to return,
directions requested by the Trustee from the Certificateholders.
 
     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 A-1 and Class A-2
Certificateholders 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 A-1 and Class A-2 Certificates 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 A-1 and Class A-2 Certificateholders,
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 balance 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 Certificateholders 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 A-1 and Class A-2 Certificateholders and
(iii) the Final Scheduled Distribution Date. See 'Description of the Trust
Agreement--Termination' in the Prospectus.
 
                           THE MARKET AGENT AGREEMENT
 
MARKET AGENT
 
     Pursuant to the Market Agent Agreement, dated as of the Closing Date,
between Lehman Brothers Inc., solely in its capacity as Market Agent (the
'Market Agent'), and the Trust (the 'Market Agent Agreement'), the Market Agent
shall: (a) act on behalf of the Trust in connection with the sale of such
portion, if any, of the Underlying Securities after a payment default on or an
acceleration of the Underlying Securities as provided in the Trust Agreement
representing fractional interests in the Underlying Securities which cannot be
distributed to Certificateholders in kind; and (b) perform its other duties and
comply with the provisions set forth in the Market Agent Agreement. The Market
Agent is entitled to a customary fee for any sale of the Underlying Securities.
 
     The Market Agent Agreement provides that the Market Agent has no liability
for any act or omission except as results from the Market Agent's negligence or
willful misconduct. The Market Agent may assign any and all of its duties,
obligations and rights as Market Agent to any organization controlled by or
under common control
 
                                      S-27
<PAGE>
with Lehman Brothers Inc. The Market Agent may at any time resign and be
discharged of the duties and obligations created by the Market Agent Agreement
by providing at least 30 days notice to the Trustee.
 
SALE OF THE UNDERLYING SECURITIES
 
     Upon receiving notice of a payment default on or an acceleration of the
Underlying Securities, the Trustee will be permitted to direct the Market Agent
to sell in compliance with the Sale Procedures such amount of the Underlying
Securities as will be necessary in order that the Underlying Securities,
together with the proceeds received from the sale of any portion thereof, may be
distributed in accordance with the Allocation Ratio. The sale and settlement of
the liquidation of such portion of the Underlying Securities will occur as soon
as practicable after the date of receipt of such notice by the Trustee, and the
liquidation proceeds will be deposited into the Certificate Account maintained
by the Trustee. Deliveries of the Underlying Securities by the Trust to the
Purchaser of such Underlying Securities will only be made against payment in
same day funds.
 
     'Sale Procedures' means, in connection with any sale of a portion of the
Underlying Securities, the sale of such Underlying Securities to the highest of
not less than three solicited bidders for such Underlying Securities (one of
which bidders may include Lehman Brothers Inc. or any one of its affiliates;
provided, however, that neither Lehman Brothers Inc. nor any of its affiliates
are obligated to bid, and that such bidders need not be limited to recognized
broker dealers). In the sole judgment of the Market Agent, bids may be evaluated

on the basis of bids for all or a portion of the Underlying Securities being
sold or any other basis selected in good faith by the Market Agent. No assurance
can be given as to whether the Market Agent will be successful in soliciting
bids to purchase the Underlying Securities. The Market Agent shall, prior to any
sale of Underlying Securities to Lehman Brothers, Inc. or any of its affiliates,
certify in writing to the Trustee that any such purchaser submitted the highest
of at least three bids and shall identify the other bidders.
 
                    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
Certificates by an initial holder of Certificates.
 
     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 Certificates as 'capital assets' (generally,
property held for investment) within the meaning of Section 1221 of the Internal
Revenue Code of 1986, as amended (the 'Code'), and who do not hold their
Certificates as part of a 'straddle,' a 'hedge' or a 'conversion transaction.'
Furthermore, no authority exists concerning the tax treatment of some aspects of
the Certificates, 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 Certificates 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 Certificates.
 
     The Trust, as discussed below, will be provided with an opinion of Weil,
Gotshal & Manges LLP, special Federal tax counsel to the Depositor ('Federal Tax
Counsel'), regarding the tax status of the Trust for Federal income tax
purposes. An opinion of Federal Tax Counsel, however, is not binding on the
Internal Revenue Service (the 'Service') or the courts. Prospective investors
should note that no rulings have been or will be sought from the Service with
respect to any of the Federal income tax consequences discussed below, and no
assurance can be given that the Service will not take contrary positions.
 
     THE TAX DISCUSSION CONTAINED HEREIN ASSUMES THAT THE AGGREGATE DEEMED
PURCHASE PRICE OF THE CERTIFICATES (AS DESCRIBED HEREIN) WILL AT LEAST EQUAL THE
STATED PRINCIPAL BALANCE OF THE UNDERLYING SECURITIES AND THAT THE UNDERLYING
SECURITIES CONSTITUTE INDEBTEDNESS FOR FEDERAL INCOME TAX PURPOSES.
 
                                      S-28
<PAGE>
TAX STATUS OF TRUST
 
     In the opinion of Federal Tax Counsel, 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 Certificate (a 'Certificateholder') will be subject to Federal income
taxation as if it owned directly the portion of the Underlying Securities
allocable to such Certificates and as if it paid directly its share of
reasonable expenses paid by the Trust.
 
INCOME OF CERTIFICATEHOLDERS
 
     In General.  The proper Federal income tax treatment of the Class A-1
Certificates is unclear. Under Code Section 1286, on the date a Certificate is
purchased, the security backing the Certificate will be treated as newly issued.
The Trust intends to take the position that the Class A-1 Certificates represent
interests in a newly-issued self-amortizing debt obligation maturing on the
Final Scheduled Distribution Date. Payments on the Certificates made on each
Distribution Date will represent partially a return of principal and partially
interest on the principal amount of such instrument. Certificateholders under
the cash method of accounting would include in income upon receipt that portion
of the payment representing interest calculated based upon the Certificate's
yield to maturity. The Service, however, could take the position that a Class
A-1 Certificate represents an interest in 40 separate newly-issued debt
instruments, each consisting of an interest payment stripped from the Underlying
Securities and maturing on its respective Distribution Date. Were the Service to
take this position, the debt instruments represented by the Class A-1
Certificates would be considered to be issued with original issue discount
('OID') and the holders would be required to accrue income based upon the
constant yield method without respect to the receipt of cash. Class A-1
Certificateholders are urged to seek advice of their own tax counsel regarding
the effect on them of the purchase of Certificates.
 
     With respect to the Class A-2 Certificate, under Section 1286, the
Underlying Security will be treated as newly issued and will be issued with OID
equal to the difference between (i) its stated redemption price at maturity
(generally all payments made with respect to the Underlying Securities to the
Class A-2 Certificate) and (ii) the Certificate's purchase price (less accrued
interest, if any, on the Underlying Securities on the Closing Date to which the
Class A-2 Certificateholder may be entitled). Each Class A-2 Certificateholder,
regardless of its normal method of accounting, will accrue income, prior to the
receipt of cash, in respect of its interest in the Underlying Securities under
the rules relating to OID under a method described below that takes account of
the compounding of interest, based on the particular Certificateholder's
expected yield to maturity.
 
     OID.  A holder of a Class A-2 Certificate (or of the Underlying Securities
after the Final Scheduled Maturity Date or redemption of the Certificates),
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 includable in income by such holder
is the sum of the 'daily portions' of OID with respect to each day during the
taxable year or portion of the taxable year in which such holder held such
obligation ('accrued OID'). The daily portion is determined by allocating to
each day in any 'accrual period' a pro rata portion of the OID allocable to the
accrual period. Under the Treasury Regulations, the 'accrual period' for each
obligation may be of any length and may vary in length over the term of the
obligation, provided that each accrual period is no longer than one year and

each scheduled payment occurs on either the first or last day of an accrual
period. The amount of OID allocable to any accrual period is an amount equal to
the product of each obligation's adjusted issue price at the beginning of such
accrual period and its yield to maturity (determined on the basis of compounding
at the close of each accrual period and properly adjusted for the length of the
accrual period). If all accrual periods are of equal length except for either an
initial short period or an initial and final short period, the amount of OID
allocable to the initial short accrual period may be computed under any
reasonable method. The 'adjusted issue price' of an interest in an Underlying
Security at the start of any accrual period is equal to its purchase price
(generally, the purchase price of the Certificate, less any purchased accrued
interest) increased by the accrued OID for each prior accrual period and reduced
by the amount of any cash payments.
 
     Because the purchase of a Certificate would be treated as the original
issuance on the purchase date of an obligation to make the distributions on the
portion of the amounts collected on the Underlying Securities
 
                                      S-29
<PAGE>
allocable to the Certificates, such purchase should not result in acquisition
premium, bond premium or market discount.
 
     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 Certificateholders on which they would recognize gain or loss.
 
DEDUCTIBILITY OF TRUST'S FEES AND EXPENSES
 
     In computing its Federal income tax liability, a Certificateholder 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. If a Certificateholder
is an individual, estate or trust, the deduction for its share of fees will be a
miscellaneous itemized deduction that may be disallowed in whole or in part.
 
PURCHASE AND SALE OF A CERTIFICATE
 
     A Certificateholder's tax basis in a Certificate generally will equal the
cost of such Certificate (A) increased by any amounts of OID and (B) reduced by
any payments other than of qualified stated interest on the Underlying
Securities made on such Certificate.
 
     If a Certificate or Underlying Security is sold, gain or loss will be
recognized in an amount equivalent to the difference between the proceeds of
sale allocable to the Certificateholder and the Certificateholder's adjusted
basis in its Certificate or its portion thereof representing its interest in the
foregoing. Any gain or loss will be a capital gain or loss if the Certificate
was held as a capital asset.
 
DISTRIBUTIONS ON CLASS A-2 CERTIFICATES

 
     The distribution of the Underlying Securities to the Class A-2
Certificateholders upon a default of the Underlying Securities or on the Final
Scheduled Distribution Date should not constitute a taxable transaction to the
recipients. Similarly, a redemption by the Trust of Certificates in exchange for
the Underlying Securities upon the tender by a Certificateholder of Class A-2
Certificates of a certain principal amount and Class A-1 Certificates
representing a like percentage of the outstanding principal amount thereof
should not constitute a taxable transaction to the Certificateholder. It is
unclear, however, whether the receipt of a portion of the Underlying Securities
by the Class A-1 Certificateholders in accordance with the Allocation Ratio upon
a default of the Underlying Securities constitutes a taxable transaction to
either the Class A-1 or Class A-2 Certificateholders. Certificateholders are
urged to consult their own tax advisers with respect to the consequences to them
of such a distribution.
 
BACKUP WITHHOLDING
 
     Payments made on the Certificates and proceeds from the sale of the
Certificates will not be subject to a 'backup' withholding tax of 31% unless, in
general, the Certificateholder fails to comply with certain reporting procedures
and is not an exempt recipient under applicable provisions of the Code.
 
FOREIGN CERTIFICATEHOLDERS
 
     To the extent that amounts paid to Certificateholders that are not United
States persons ('Foreign Certificateholders') 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 Certificateholder 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.
 
     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, an estate the income of
which is includable in gross income for Federal income tax purposes, regardless
of its source, or a trust with
 
                                      S-30
<PAGE>
respect to which a court within the United States is able to exercise primary
supervision over its administration and one or more U.S. fiduciaries have the
authority to control all of its substantial decisions.
 
                              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) 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 Certificate, 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 Certificates should also consider whether
such an investment might constitute or give rise to a non-exempt prohibited
transaction under ERISA or the Code.
 
     Under a 'look-through rule' set forth in Section 2510.3-101 of the United
States Department of Labor ('DOL') 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 Certificates 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, Market Agent, Underlying
Securities Trustee and the Company might constitute prohibited transactions with
respect to a Plan holding a Certificate unless (i) one or more prohibited
transaction exemptions ('PTEs') applies or (ii) in the case of the Company, 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,
Market Agent, Underlying Securities Trustee and the Company, or any of their
affiliates ('Excluded Plans'), should not acquire or hold any Certificate.
 
     If the Trust is deemed to hold Plan assets, the Underlying Securities would
appear to be an indirect loan between the Company and any Plan owning
Certificates; however, such loan, by itself, would not constitute a prohibited
transaction unless the Company is a party in interest or disqualified person
with respect to such Plan.
 
     The Underwriter is a broker-dealer registered under the Securities Exchange
Act of 1934, as amended, 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 Certificates 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, Market Agent 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 and
the Market Agent may each be terminated upon 60 days prior notice and the
approval of Certificateholders owning more than 66 2/3% of the aggregate
beneficial interest of Certificates. The Depositor believes the compensation of
the Trustee and Market Agent is reasonable under the circumstances. The
statutory exemption for services noted
 
                                      S-31
<PAGE>
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 a
portion of the Underlying Securities by the Market Agent to Lehman Brothers Inc.
or its affiliates might constitute a non-exempt prohibited transaction by reason
of the relationship between the Market Agent and any such purchaser,
notwithstanding the sale procedure to accept the highest bid submitted and the
certification of the highest bid and identity of bidders to the Trustee, or the
possibility that the Market Agent may not solicit Lehman Brothers Inc. and its
affiliates to avoid the possibility of a non-exempt prohibited transaction. The
Market Agent shall, prior to any sale of Underlying Securities to Lehman
Brothers Inc. or any of its affiliates, certify in writing to the Trustee 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 Certificates by Plans, and the operation of the Trust, including, but
not limited to: PTE 84-14 (an exemption for certain transactions 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 general accounts).
 
     By acquiring and holding a Certificate, a Plan shall be deemed to have
represented and warranted to the Depositor, Trustee, Market Agent and
Underwriter that such acquisition and holding of a Certificate does not involve
a non-exempt prohibited transaction with respect to such Plan, including with
respect to the activities of the Trust.
 
                             METHOD OF DISTRIBUTION
 
     Subject to the terms and conditions set forth in the Underwriting
Agreement, dated December 16, 1997 (the 'Underwriting Agreement'), the Depositor
has agreed to sell to Lehman Brothers Inc., (an affiliate of the Depositor) (the
'Underwriter'), and the Underwriter has agreed to purchase, the Certificates.
 
     The Depositor has been advised by the Underwriter that the Underwriter
proposes to offer the Certificates 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 Certificates 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
Certificates for whom they may act as agents. The Underwriter and any dealers
that participate with the Underwriter in the distribution of Certificates may be
deemed to be underwriters, and any profit on the resale of Certificates 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 2.5% of
the face amount of the Certificates.
 
     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.
 
                                 LEGAL MATTERS
 
     Certain legal matters relating to the Certificates will be passed upon for
the Depositor and the Underwriter by Weil, Gotshal & Manges LLP, New York, New
York.
 
                                    RATINGS
 
     It is a condition to the issuance of the Certificates that the Certificates
have ratings assigned by Moody's Investors Service, Inc. ('Moody's') and by
Standard & Poor's, 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 'Aa1' by Moody's and 'AAA' by S&P. It is
expected that the ratings of the Certificates will change if the ratings of the
Underlying Securities change.
 
                                      S-32
<PAGE>
     The rating of the Certificates by Moody's addresses the likelihood that
Certificateholders will receive the timely payment of interest and principal on
a semi-annual basis beginning on January 15, 1998 and lasting until the Final
Scheduled Distribution Date. The rating of the Certificates by S&P addresses the
likelihood of timely receipt of interest on the Class A-1 Certificates or any
Underlying Securities distributed in respect of the Class A-2 Certificates and
ultimate receipt of principal on any Underlying Securities distributed in
respect of the Class A-2 Certificates. The ratings address the likelihood of the
receipt by Certificateholders of payments required under the Trust Agreement,
and are based primarily on the credit quality of the Underlying Securities. The
rating on the Certificates 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.
 
     The Depositor has not requested a rating on the Certificates 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 Certificates, or, if it does, what

rating would be assigned by any such other rating agency. A rating on the
Certificates by another rating agency, if assigned at all, may be lower than the
ratings assigned to the Certificates by the Rating Agencies.

PROSPECTUS
                               TRUST CERTIFICATES
                              (ISSUABLE IN SERIES)
                             LEHMAN ABS CORPORATION
                                   DEPOSITOR
 
     The Trust Certificates (the 'Certificates') 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 dollars or in
one or more foreign or composite currencies, including the European Currency
Unit ('ECU'). Certificates of each respective Series and Class will be offered
on terms to be determined at the time of sale as described in the related
Prospectus Supplement accompanying the delivery of this Prospectus. Certificates
may be sold for United States dollars or for one or more foreign or composite
currencies, and the principal of, premium, if any, and any interest to be
distributed in respect of Certificates may be payable in United States dollars
or in one or more foreign or composite currencies. Each Series and Class of
Certificates may be issuable as individual securities in registered form without
coupons ('Registered Certificates') or in bearer form with or without coupons
attached ('Bearer Certificates') or as one or more global securities in
registered or bearer form (each a 'Global Security').
 
     Each Series of Certificates will represent in the aggregate the entire
beneficial ownership interest in a publicly issued, fixed income debt security
or a pool of such debt securities (the 'Underlying Securities'), together with
certain other assets described herein and in the related 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
Certificates of such Series ('Certificateholders') by Lehman ABS Corporation
(the 'Depositor') pursuant to a Trust Agreement and a series supplement thereto
with respect to any given Series (collectively, the 'Trust Agreement') among the
Depositor, the administrative agent, if any (the 'Administrative Agent') and the
trustee (the 'Trustee') named in the related Prospectus Supplement. The
Underlying Securities will be purchased by the Depositor in the secondary market
(either directly or through an affiliate of the Depositor), and will not be
acquired from the issuer thereof as part of any distribution by or pursuant to
any agreement with such issuer. The Underlying Securities discussed herein and
in the related Prospectus Supplement represent the obligation of one or more
corporations, banking organizations or insurance companies organized under the
laws of the United States or any State, which are subject to the information
requirements of the Securities Exchange Act of 1934, as amended, and which, in
accordance therewith, file reports and other information with the Securities and
Exchange Commission. If so specified in the related Prospectus Supplement, the
Trust for a Series of Certificates may also include, or the Certificateholders
of such Certificates 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'). See
'Description of Certificates' and 'Description of Deposited Assets and Credit
Support.'
 
     Each Class of Certificates of any Series will represent the right, which

may be senior to those of one or more of the other Classes of such Series, to
receive specified portions of payments of principal, interest and certain other
amounts on the Deposited Assets in the manner described herein and in the
related Prospectus Supplement. A Series may include two or more Classes
differing as to the timing, sequential order or amount of distributions of
principal, interest or premium and one or more Classes within such Series may be
subordinated in certain respects to other Classes of such Series.
 
     Except as otherwise provided herein and in the applicable Prospectus
Supplement, the Depositor's only obligations with respect to each Series of
Certificates will be, pursuant to certain representations and warranties
concerning the Deposited Assets, to assign and deliver the Deposited Assets and
certain related documents to the applicable Trustee and, in certain cases, to
provide for the 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 Certificates will be pursuant to its contractual
administrative obligations and, only as and to the extent provided in the
related Prospectus Supplement, its obligation to make certain cash advances in
the event of payment delinquencies on the Deposited Assets. See 'Description of
the Certificates--Advances in Respect of Delinquencies.'
 
     The Certificates of each Series will not represent an obligation of or
interest in the Depositor, any Administrative Agent or any of their respective
affiliates, except to the limited extent described herein and in the related
Prospectus Supplement. Neither the Certificates 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, any
Administrative Agent or their respective affiliates.
 
     Prospective investors should consider the factors set forth herein under
'Risk Factors,' beginning on page 4.
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
     EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
        COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
            ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE
                                 CONTRARY IS A CRIMINAL OFFENSE.
 
     The Certificates may be offered and sold to or through underwriters,
dealers or agents or directly to purchasers, as more fully described under 'Plan
of Distribution' and in the related Prospectus Supplement. This Prospectus may
not be used to consummate sales of Certificates offered hereby unless
accompanied by a Prospectus Supplement.

                             AVAILABLE INFORMATION
 
     The Depositor is subject to the informational requirements of the
Securities Exchange Act of 1934, as amended (the 'Exchange Act'), and in
accordance therewith files reports and other information with the Securities and
Exchange Commission (the 'Commission'). Reports and other information concerning
the Depositor can be inspected and copied at the public reference facilities
maintained by the Commission at Room 1024, 450 Fifth Street, N.W., Washington,
D.C. 20549, and at the Commission's Regional Offices at Seven World Trade
Center, New York, New York 10048, and Northwestern Atrium Center, 500 West
Madison Street, Suite 1400, Chicago, Illinois 60661. Copies of such material can
be obtained upon written request addressed to the Commission, Public Reference
Section, 450 Fifth Street, N.W., Washington, D.C. 20549, at prescribed rates.
The Depositor does not intend to send any financial reports to
Certificateholders.
 
     The Depositor has filed with the Commission a registration statement on
Form S-3 (together with all amendments and exhibits, the 'Registration
Statement') under the Securities Act of 1933, as amended (the 'Securities Act'),
relating to the Certificates. This Prospectus does not contain all the
information set forth in the Registration Statement, certain parts of which are
omitted in accordance with the rules and regulations of the Commission. For
further information, reference is hereby made to the Registration Statement.
 
                INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE
 
     All documents filed by the Depositor pursuant to Section 13(a), 13(c), 14
or 15(d) of the Exchange Act subsequent to the date of this Prospectus and prior
to the termination of the offering of the Certificates shall be deemed to be
incorporated by reference in this Prospectus. Any statement contained herein or
in a document incorporated or deemed to be incorporated by reference herein

shall be deemed to be modified or superseded for purposes of this Prospectus to
the extent that a statement contained herein or in any subsequently filed
document which also is or is deemed to be incorporated by reference herein
modifies or supersedes such statement. Any such statement so modified or
superseded shall not be deemed, except as so modified or superseded, to
constitute a part of this Prospectus.
 
     The Depositor will provide without charge to each person to whom a copy of
this Prospectus is delivered, on the written or oral request of any such person,
a copy of any or all of the documents incorporated herein by reference, except

incorporated by reference in such documents). Written requests for such copies
should be directed to the Secretary of Lehman ABS

Corporation, 3 World Financial Center, New York, New York 10285. Telephone
requests for such copies should be directed to the Secretary of Lehman ABS
Corporation at (212) 526-5594.
 
                         REPORTS TO CERTIFICATEHOLDERS
 
     Except as otherwise specified in the applicable Prospectus Supplement,
unless and until Definitive Certificates are issued, on each Distribution Date
unaudited reports containing information concerning the related Trust will be
prepared by the related Trustee and sent on behalf of each Trust only to Cede &
Co. ('Cede'), as nominee of DTC and registered holder of the Certificates. See
'Description of Certificates--Global Securities' and 'Description of the Trust
Agreement--Reports to Certificateholders; Notice.' Such reports will not
constitute financial statements prepared in accordance with generally accepted
accounting principles. The Depositor, on behalf of each Trust, will cause to be
filed with the Commission such periodic reports as are required under the
Exchange Act.
 
                         IMPORTANT CURRENCY INFORMATION
 
     Purchasers are required to pay for each Certificate in the Specified
Principal Currency for such Certificate. Currently, there are limited facilities
in the United States for conversion of U.S. dollars into foreign currencies and
vice versa, and banks do not currently offer non-U.S. dollar checking or savings
account facilities in the United States. However, if requested by a prospective
purchaser of a Certificate having a Specified Principal Currency other than U.S.
dollars, Lehman Brothers Inc. (the 'Offering Agent') will arrange for the
exchange of U.S. dollars into such Specified Principal Currency to enable the
purchaser to pay for such Certificate. Such request must be made on or before
the fifth Business Day (as defined below) preceding the date of delivery of such
Certificate or by such later date as is determined by the Offering Agent. Each
such exchange will be made by the Offering Agent on such terms and subject to
such conditions, limitations and charges as the Offering Agent may from time to
time establish in accordance with its regular foreign exchange practice. All
costs of exchange will be borne by the purchaser.
 
     References herein to 'U.S. dollars,' 'U.S.$,' 'USD,' 'dollar' or '$' are to
the lawful currency of the United States.

<PAGE>
                                  RISK FACTORS
 
     Limited Liquidity. There will be no market for any Series (or Class within
such Series) of Certificates prior to the issuance thereof, and there can be no
assurance that a secondary market will develop or, if it does develop, that it
will provide Certificateholders with liquidity of investment or will continue
for the life of such Certificates.
 
     Certain Legal Aspects. The applicable Prospectus Supplement may set forth
certain legal considerations that are applicable to a specific Series (or Class
or Classes within such Series) of Certificates being offered in connection with
that Prospectus Supplement or the assets deposited in or assigned to the related
Trust.
 
     Limited Obligations and Interest. The Certificates will not represent a
recourse obligation of or interest in the Depositor or any of its affiliates.
Unless otherwise specified in the applicable Prospectus Supplement, the
Certificates of each Series will not be insured or guaranteed by any government
agency or instrumentality, the Depositor, any Person affiliated with the
Depositor or the Issuer, or any other Person. The obligations, if any, of the
Depositor with respect to the Certificates of any Series will only be pursuant
to certain limited representations and warranties. The Depositor does not have,
and is not expected in the future to have, any significant assets with which to
satisfy any claims arising from a breach of any representation or warranty. If,
for example, the Depositor were required to repurchase a Underlying Security
with respect to which the Depositor has breached a representation or warranty,
its only sources of funds to make such repurchase would be from funds obtained
from the enforcement of a corresponding obligation, if any, on the part of the
seller of such Underlying Security to the Depositor, or from a reserve fund
established to provide funds for such repurchases. The Depositor has no
obligation to establish or maintain any such reserve fund.
 
     Credit Support; Limited Assets. Although the Trust for any Series (or Class
of such Series) of Certificates may include, or the Certificateholders of such
Certificates may have the benefit of, certain assets which are designed to
support the payment upon, or otherwise ensure the servicing or distribution with
respect to, the Deposited Asset related to such Series or Class as described in
the related Prospectus Supplement, the Certificates do not represent obligations
of the Depositor, any Administrative Agent 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, any of their
affiliates or any other person or entity. Accordingly, Certificateholders'
receipt of distributions in respect of the Certificates will depend entirely on
the performance of and the Trust's receipt of payments with respect to the
Deposited Assets and any Credit Support identified in the related Prospectus
Supplement. See 'Description of Deposited Assets and Credit Support.'
 
     Maturity and Redemption Considerations. The timing of distributions of
interest, premium (if any) and principal of any Series (or of any Class within
such Series) of Certificates is affected by a number of factors, including the
performance of the related Deposited Assets, the extent of any early redemption,

repayment or extension of maturity with respect to the related Underlying
Securities (including acceleration resulting from any default or rescheduling
resulting from the bankruptcy or similar proceeding with respect to a Underlying
Securities Issuer) and the manner and priority in which collections from such
Underlying Securities and any other Deposited Assets are allocated to each Class
of such Series. Certain of these factors may be influenced by a variety of
accounting, tax, economic, social and other factors. The related Prospectus
Supplement will discuss any calls, puts or other redemption options, any
extension of maturity provisions and certain other terms applicable to such
Underlying Securities and any other Deposited Assets. See 'Maturity and Yield
Considerations.'
 
     Tax Considerations. The Federal income tax consequences of the purchase,
ownership and disposition of the Certificates and the tax treatment of the Trust
will depend on the specific terms of the Certificates, the Trust, any Credit
Support and the Deposited Assets. See the description under 'Certain Federal
Income Tax Considerations' in the related Prospectus Supplement.
 
     Ratings of the Certificates. At the time of issue, the Certificates of any
given Series (or each Class of such Series that is offered hereby) will be rated
in one of the investment grade categories recognized 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
Certificates is based primarily on the related Deposited Assets and any Credit
Support and the relative priorities of the Certificateholders of such Series or
Class to receive collections from, and to assert claims against, the Trust with
respect to such Deposited Assets
 
                                       4
<PAGE>
and any Credit Support. The rating is not a recommendation to purchase, hold or
sell Certificates, inasmuch as such rating does not comment as to market price
or suitability for a particular investor. There can be no assurance that the
rating will remain for any given period of time or that the rating will not be
lowered or withdrawn entirely by the Rating Agency if in its judgment
circumstances in the future so warrant. Any Class or Classes of a given Series
of Certificates may not be offered pursuant to this Prospectus, in which case
such Class or Classes may or may not be rated in an investment grade category by
a Rating Agency.
 
     Global Securities. Unless otherwise specified in the related Prospectus
Supplement, the Certificates of each Series (or, if more than one Class exists,
each Class of such Series) will initially be represented by one or more Global
Securities deposited with, or on behalf of, a Depository (as defined below) and
will not be issued as individual definitive Certificates to the purchasers of
such Certificates. Consequently, unless and until such individual definitive
Certificates of a particular Series or Class are issued, such purchasers will
not be recognized as Certificateholders under the Trust Agreement. Hence, until
such time, such purchasers will only be able to exercise the rights of
Certificateholders indirectly through the Depository and its respective
participating organizations and, as a result, the ability of any such purchaser
to pledge that Certificate to persons or entities that do not participate in the
Depository's system, or otherwise to act with respect to such Certificate, may
be limited. See 'Description of Certificates--Global Securities' and

'Limitations on Issuance of Bearer Certificates' and any further description
contained in the related Prospectus Supplement.
 
     Currency Risks. The Certificates of any given Series (or Class within such
Series) may be denominated in a currency other than U.S. dollars to the extent
specified in the applicable Prospectus Supplement. This Prospectus does not
describe all the risks of an investment in such Certificates, and the Depositor
disclaims any responsibility to advise prospective purchasers of such risks as
they exist from time to time. Prospective purchasers of such Certificates should
consult their own financial and legal advisors as to the risks entailed by an
investment in such Certificates denominated in a currency other than U.S.
dollars. See 'Currency Risks.'
 
     Passive Nature of the Trust. The Trustee with respect to any Series of
Certificates will hold the Deposited Assets for the benefit of the
Certificateholders. 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. Under certain circumstances the holders of the Certificates
may direct the Trustee to dispose of the Underlying Securities or take certain
other actions in respect of the Deposited Assets.
 
     The Prospectus Supplement for each Series of Certificates will set forth
information regarding additional risk factors, if any, applicable to such Series
(and each Class within such Series).
 
                                 THE DEPOSITOR
 
     The Depositor was incorporated in the State of Delaware on January 29,
1988, as an indirect, wholly owned, limited-purpose subsidiary of Lehman
Brothers Inc. The principal office of the Depositor is located at 3 World
Financial Center, New York, New York 10285. Its telephone number is (212)
526-5594.
 
     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 Certificates. 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 Certificates of any Series.
 
                                USE OF PROCEEDS
 
     Unless otherwise specified in the applicable Prospectus Supplement, the net
proceeds to be received from the sale of each Series or Class of Certificates
(whether or not offered hereby) will be used by the Depositor to purchase the
related Deposited Assets and arrange certain Credit Support, including, if
specified in the related
 

                                       5
<PAGE>
Prospectus Supplement, making required deposits into any reserve account or the
applicable Certificate Account (as defined below) for the benefit of the
Certificateholders of such Series or Class. Any remaining net proceeds, if any,
will be used by the Depositor for general corporate purposes.
 
                             FORMATION OF THE TRUST
 
     The Depositor will assign the Deposited Assets for each Series of
Certificates to the Trustee named in the applicable Prospectus Supplement, in
its capacity as Trustee, for the benefit of the Certificateholders 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.' The Trustee or an Administrative Agent, if applicable,
will either cause the assignment of the Deposited Assets to be recorded on the
books and records of DTC 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 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 in amounts 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 related 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 by the Depositor
or any previous owner thereof, 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 Certificate Account; (iii) property, if any, acquired on behalf of
Certificateholders by foreclosure or repossession and any revenues received
thereon; (iv) those elements of Credit Support, if any, provided with respect to
any Class 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 and Credit Support--Credit Support'; (v) the
rights of the Depositor under the agreement or agreements entered into by the
Trustee on behalf of the Certificateholders which constitute, or pursuant to
which the Trustee has acquired, such Deposited Assets; and (vi) the rights of
the Trustee in any cash advances, reserve fund or surety bond, if any, as
described under 'Description of the Trust Agreement-- Advances in Respect of
Delinquencies.'
 
     In addition, to the extent provided in the applicable Prospectus
Supplement, the Depositor will obtain Credit Support for the benefit of the
Certificateholders of any related Series (or Class within such Series) of
Certificates.
 
                       MATURITY AND YIELD CONSIDERATIONS
 
     Each Prospectus Supplement will, to the extent applicable, contain
information with respect to the type and maturities of the related Underlying
Securities and the terms, if any, upon which such Underlying Securities may be
subject to early redemption (either by the applicable obligor or pursuant to a
third-party call option), repayment (at the option of the holders thereof) or
extension of maturity. The provisions of the Underlying
 
                                       6
<PAGE>
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 Certificates.
 
     The effective yield to holders of the Certificates of any Series (and Class
within such Series) may be affected by certain aspects of the Deposited Assets
or any Credit Support 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 Certificates the Underlying Securities of which
consist of one or more redeemable securities, extendable securities or
securities subject to a third-party call option, the yield to maturity of such
Series (or Class within such Series) may be affected by any optional or
mandatory redemption or repayment or extension 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 fall significantly 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 related Prospectus Supplement, each of
the Underlying Securities will be subject to acceleration upon the occurrence of
certain Underlying Security Events of Default (as defined below). The maturity
and yield on the Certificates will be affected by any early repayment of the
Underlying Securities as a result of the acceleration of the Outstanding Debt
Securities by 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 both interest and principal may be materially and adversely
affected. A variety of factors influence the performance of private debt issuers
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 social, geographic, legal and
economic factors.
 
     The extent to which the yield to maturity of such Certificates 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 Certificates will also be
affected by variations in the interest rates applicable to, and the
corresponding payments in respect of, such Certificates, to the extent that the
Pass-Through Rate for such Series (or Class) is based on variable or adjustable
interest rates. With respect to any Series of Certificates representing an
interest in a pool of corporate debt 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
Pass-Through Rates applicable to such Certificates may affect the yield thereon.
 
     The Prospectus Supplement for each Series of Certificates 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 CERTIFICATES
 
     Each Series (or, if more than one Class exists, the Classes within such
Series) of Certificates will be issued pursuant to a Trust Agreement and a
separate series supplement thereto among the Depositor, the Administrative
Agent, if any, and the Trustee named in the related 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 nature of the Certificates to be issued thereunder and the
nature of the Deposited Assets, Credit Support and related Trust. The following
summaries describe certain provisions of the Trust Agreement which may be
applicable to each Series of Certificates. The applicable Prospectus Supplement
for a Series of Certificates will describe any provision of the Trust Agreement
that materially differs from the description thereof contained in this
Prospectus. 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
 
                                       7
<PAGE>
description of such provisions, including the definition of certain terms used,
and for other information regarding the Certificates. Article and section
references in parentheses below are to articles and sections in the Trust
Agreement. Wherever particular sections or defined terms of the Trust Agreement

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. As used herein with respect to any Series, the term
'Certificate' refers to all the Certificates of that Series, whether or not
offered hereby and by the related Prospectus Supplement, unless the context
otherwise requires.
 
     A copy of the applicable series supplement to the Trust Agreement relating
to each Series of Certificates issued from time to time will be filed by the
Depositor as an exhibit to a Current Report on Form 8K to be filed with the
Commission following the issuance of such Series.
 
GENERAL
 
     There is no limit on the amount of Certificates that may be issued under
the Trust Agreement, and the Trust Agreement will provide that Certificates of
the applicable Series may be issued in multiple Classes (Section 5.01). Each
Series (or Classes within such Series) of Certificates 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 and Credit Support--
Collections.'
 
     Reference is made to the related Prospectus Supplement for a description of

each case to the extent not inconsistent with the Depositor's continued
satisfaction of the applicable requirements for exemption under Rule 3a-7 under
the Investment Company Act of 1940 and all applicable rules, regulations and
interpretations thereunder) 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; (ix) the rating of each Series or each Class within such
Series offered hereby (provided, however, that one or more Classes within such

disproportionate,
 
                                       8
<PAGE>
nominal or no principal distributions ('Strip Certificates'), and the applicable
terms thereof; (xii) whether the Certificates of such Series or of any Class

definitive Certificate of such Series or Class will be credited to the account
of the Persons entitled thereto on such Distribution Date; (xv) if a temporary
Global Security is to be issued with respect to such Series or Class, the terms

Depositor or the applicable Administrative Agent, if any, or Trustee under the
Trust Agreement or with respect to the applicable Trust; and (xix) any other
terms of such Series or Class within such Series of Certificates not
inconsistent with the provisions of the Trust Agreement relating to such Series.
 
     Unless otherwise indicated in the applicable Prospectus Supplement,
Certificates of each Series (including any Class of Certificates not offered
hereby) will be issued only as Registered Certificates in denominations of
$1,000 and any integral multiple thereof and will be payable only in U.S.
dollars (Section 5.01). The authorized denominations of Registered Certificates
of a given Series or Class within such Series having a Specified Currency other
than U.S. dollars will be set forth in the applicable Prospectus Supplement.
 
     The United States Federal income tax consequences and ERISA consequences
relating to any Series or any Class within such Series of Certificates 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 Bearer Certificates or
Certificates 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 Certificate having a Specified Principal
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 (the
'Market Exchange Rate') for such Specified Principal 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
Certificates (the 'Exchange Rate Agent').
 
     Unless otherwise provided in the applicable Prospectus Supplement,
Registered Certificates may be transferred or exchanged for like Certificates of
the same Series and Class 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
(Section 5.04). Bearer Certificates will be transferable by delivery. Provisions
with respect to the exchange of Bearer Certificates will be described in the
applicable Prospectus Supplement. Unless otherwise specified in the applicable
Prospectus Supplement, Registered Certificates may not be exchanged for
 
                                       9
<PAGE>
Bearer Certificates. The Depositor may at any time purchase Certificates at any
price in the open market or otherwise. Certificates so purchased by the
Depositor may, at the discretion of the Depositor, be held or resold or
surrendered to the Trustee for cancellation of such Certificates.
 
DISTRIBUTIONS
 

     Distributions allocable to principal, premium (if any) and interest on the
Certificates of each Series (and Class within such Series) will be made in the
Specified Currency for such Certificates by or on behalf of the Trustee on each
Distribution Date as specified in the related Prospectus Supplement and the
amount of each distribution will be determined as of the close of business on
the date specified in the related Prospectus Supplement (the 'Determination
Date'). If the Specified Currency for a given Series or Class within such Series
is other than U.S. dollars, the Administrative Agent, if any, or otherwise the
Trustee will (unless otherwise specified in the applicable Prospectus
Supplement) arrange to convert all payments in respect of each Certificate of
such Series or Class to U.S. dollars in the manner described in the following
paragraph. The Certificateholder of a Registered Certificate of a given Series
or Class within such Series denominated in a Specified Currency other than U.S.
dollars may (if the applicable Prospectus Supplement and such Certificate so
indicate) elect to receive all distributions in respect of such Certificate in
the Specified Currency by delivery of a written notice to the Trustee and
Administrative Agent, if any, for such Series not later than fifteen calendar
days prior to the applicable Distribution Date, except under the circumstances
described under 'Currency Risks--Payment Currency' below. Such election will
remain in effect until revoked by written notice to such Trustee and
Administrative Agent, if any, received by each of them not later than fifteen
calendar days prior to the applicable Distribution Date.
 
     Unless otherwise specified in the applicable Prospectus Supplement, in the
case of a Registered Certificate of a given Series or Class within such Series
having a Specified Currency other than U.S. dollars, the amount of any U.S
dollar distribution in respect of such Registered Certificate will be determined
by the Exchange Rate Agent based on the highest firm bid quotation expressed in
U.S. dollars received by the Exchange Rate Agent at approximately 11:00 a.m.,
New York City time, on the second Business Day preceding the applicable
Distribution Date (or, if no such rate is quoted on such date, the last date on
which such rate was quoted), from three (or, if three are not available, then
two) recognized foreign exchange dealers in The City of New York (one of which
may be the Offering Agent and another of which may be the Exchange Rate Agent)
selected by the Exchange Rate Agent, for the purchase by the quoting dealer, for
settlement on such Distribution Date, of the aggregate amount payable in such
Specified Currency on such payment date in respect of all Registered
Certificates. All currency exchange costs will be borne by the
Certificateholders of such Registered Certificates by deductions from such
distributions. If no such bid quotations are available, such distributions will
be made in such Specified Currency, unless such Specified Currency is
unavailable due to the imposition of exchange controls or to other circumstances
beyond the Depositor's control, in which case such distributions will be made as
described under 'Currency Risks--Payment Currency' below. The applicable
Prospectus Supplement will specify such information with respect to Bearer
Certificates.
 
     Unless otherwise provided in the applicable Prospectus Supplement and
except as provided in the succeeding paragraph, distributions with respect to
Certificates will be made (in the case of Registered Certificates) at the
corporate trust office or agency of the Trustee specified in the applicable
Prospectus Supplement in The City of New York or (in the case of Bearer
Certificates) at the principal London office of the applicable Trustee;
provided, however, that any such amounts distributable on the final Distribution

Date of a Certificate will be distributed only upon surrender of such
Certificate at the applicable location set forth above (Sections 4.01 and 9.01).
Except as otherwise provided in the applicable Prospectus Supplement, no
distribution on a Bearer Certificate will be made by mail to an address in the
United States or by wire transfer to an account maintained by the
Certificateholder thereof in the United States.
 
     Unless otherwise specified in the applicable Prospectus Supplement,
distributions on Registered Certificates in U.S. dollars will be made, except as
provided below, by check mailed to the Registered Certificateholders of such
Certificates (which, in the case of Global Securities, will be a nominee of the
Depository); provided, however, that, in the case of a Series or Class of
Registered Certificates issued between a Record Date (as defined below) and the
related Distribution Dates, interest for the period beginning on the issue date
for such Series or Class and ending on the last day of the interest accrual
period ending immediately prior to or coincident with
 
                                       10
<PAGE>
such Distribution Date will, unless otherwise specified in the applicable
Prospectus Supplement, be distributed on the next succeeding Distribution Date
to the Registered Certificateholders of the Registered Certificates of such
Series or Class on the related Record Date. A Certificateholder of $10,000,000
(or the equivalent thereof in a Specified Principal Currency other than U.S.
dollars) or more in aggregate principal amount of Registered Certificates of a
given Series shall be entitled to receive such U.S. dollar 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.
Simultaneously with the election by any Certificateholder to receive payments in
a Specified Currency other than U.S. dollars (as provided above), such
Certificateholder shall provide appropriate wire transfer instructions to the
Trustee for such Series, and all such payments will be made by wire transfer of
immediately available funds to an account maintained by the payee with a bank
located outside the United States.
 
     Except as otherwise specified in the applicable Prospectus Supplement,
'Business Day' with respect to any Certificate means any day, other than a
Saturday or Sunday, that is (i) not a day on which banking institutions are
authorized or required by law or regulation to be closed in (a) The City of New
York or (b) if the Specified Currency for such Certificate is other than U.S.
dollars, the financial center of the country issuing such Specified Currency
(which, in the case of ECU, shall be Brussels, Belgium) and (ii) if the
Pass-Through Rate for such Certificate is based on LIBOR, a London Banking Day.
'London Banking Day' with respect to any Certificate means any day on which
dealings in deposits in the Specified Currency of such Certificate are
transacted in the London interbank market. The Record Date with respect to any
Distribution Date for a Series or Class of Registered Certificates shall be
specified as such in the applicable Prospectus Supplement.
 
INTEREST ON THE CERTIFICATES
 
     General. Each Class of Certificates (other than certain Classes of Strip
Certificates) of a given Series may have a different Pass-Through Rate, which

may be a fixed or variable Pass-Through Rate, as described below. In the case of
Strip Certificates with no or, in certain cases, a nominal Certificate Principal
Balance, such distributions of interest will be in an amount (as to any
Distribution Date, 'Stripped Interest') described in the related Prospectus
Supplement. For purposes hereof, 'Notional Amount' means the notional principal
amount specified in the applicable Prospectus Supplement on which interest on
Strip Certificates with no or, in certain cases, a nominal Certificate Principal
Balance will be made on each Distribution Date. Reference to the Notional Amount
of a Class of Strip Certificates herein or in a Prospectus Supplement does not
indicate that such Certificates 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 related
Prospectus Supplement.
 
     Fixed Rate Certificates. Each Series (or, if more than one Class exists,
each Class within such Series) of Certificates with a fixed Pass-Through Rate
('Fixed Rate Certificates') will bear interest, on the outstanding Certificate
Principal Balance (or Notional Amount, if applicable), from its Original Issue
Date, or from the last date to which interest has been paid, at the fixed
Pass-Through 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 Certificates with no or a nominal
principal amount, until the Notional Amount thereof is reduced to zero), except
that, if so specified in the applicable Prospectus Supplement, the Pass-Through
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 Certificates 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 Certificates 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 Certificates will
be computed on the basis of a 360-day year of twelve 30-day months.
 
     Floating Rate Certificates. Each Series (or, if more than one Class exists,
each Class within such Series) of Certificates with a variable Pass-Through Rate
('Floating Rate Certificates') will bear interest, on the outstanding
Certificate Principal Balance (or Notional Amount, if applicable), from its
Original Issue Date to the first Interest Reset Date (as defined below) for such
Series or Class at the Initial Pass-Through Rate set forth on
 
                                       11
<PAGE>
the face thereof and in the applicable Prospectus Supplement. Thereafter, the
Pass-Through Rate on such Series or Class 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 '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 or Class,
and the 'Spread Multiplier' is the percentage that may be specified in the

applicable Prospectus Supplement as being applicable to such Series or Class,
except that if so specified in the applicable Prospectus Supplement, the Spread
or Spread Multiplier on such Series or any such Class or Classes of Floating
Rate Certificates may be subject to adjustment from time to time in response to
designated changes in the rating assigned to such Certificates 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 Certificate: (i) LIBOR (a 'LIBOR Certificate'),
(ii) the Commercial Paper Rate (a 'Commercial Paper Rate Certificate'), (iii)
the Treasury Rate (a 'Treasury Rate Certificate'), (iv) the Federal Funds Rate
(a 'Federal Funds Rate Certificate'), (v) the CD Rate (a 'CD Rate Certificate')
or (vi) such other Base Rate (which may be based on, among other things, one or
more market indices or the interest and/or other payments (whether scheduled or
otherwise) paid, accrued or available with respect to a designated asset, pool
of assets or type of asset) as is set forth in such Prospectus Supplement and in
such Certificate. The 'Index Maturity' for any Series or Class of Floating Rate
Certificates 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
publications, 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' published by the Federal
Reserve Bank of New York.
 
     As specified in the applicable Prospectus Supplement, Floating Rate
Certificates of a given Series or Class 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 Pass-Through Rate') and (ii) a minimum limitation, or
floor, on the rate at which interest may accrue during any such interest accrual
period ('Minimum Pass-Through Rate'). In addition to any Maximum Pass-Through
Rate that may be applicable to any Series or Class of Floating Rate
Certificates, the Pass-Through Rate applicable to any Series or Class of
Floating Rate Certificates will in no event be higher than the maximum rate
permitted by applicable law, as the same may be modified by United States law of
general application. The Floating Rate Certificates will be governed by the law
of the State of New York and, under such 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 Pass-Through Rates on each Series or Class of
Floating Rate Certificates. The applicable Prospectus Supplement will set forth
the identity of the Calculation Agent for each Series or Class of Floating Rate
Certificates. All determinations of interest by the Calculation Agent shall, in
the absence of manifest error, be conclusive for all purposes and binding on the
holders of Floating Rate Certificates of a given Series or Class.
 
     The Pass-Through Rate on each Class of Floating Rate Certificates will be
reset daily, weekly, monthly, quarterly, semiannually or annually (such period
being the 'Interest Reset Period' for such Class, 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, and any Class within such Series of Floating Rate Certificates, will be
specified in the applicable Prospectus Supplement; provided, however, that
unless otherwise specified in such Prospectus Supplement, the Pass-Through Rate
in effect for the ten days immediately prior to the Scheduled Final Distribution
Date will be that in effect on the tenth day preceding such Scheduled Final
Distribution Date. If an Interest Reset Date for any Class of Floating Rate
Certificates would otherwise be a day that is not a Business Day, such Interest
Reset Date will occur on a prior or succeeding Business Day, specified in the
applicable Prospectus Supplement.
 
     Unless otherwise specified in the applicable Prospectus Supplement,
interest payable in respect of Floating Rate Certificates shall be the accrued
interest from and including the Original Issue Date of such Series or Class
 
                                       12
<PAGE>
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 Certificate, accrued interest shall be
calculated by multiplying the Certificate Principal Balance of such Certificate
(or, in the case of a Strip Certificate with no or a nominal Certificate
Principal Balance, the Notional Amount specified in the applicable Prospectus
Supplement) 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 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 Pass-Through Rate in effect on such day by 360, in
the case of LIBOR Certificates, Commercial Paper Rate Certificates, Federal
Funds Rate Certificates and CD Rate Certificates or by the actual number of days
in the year, in the case of Treasury Rate Certificates. For purposes of making
the foregoing calculation, the variable Pass-Through 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 Pass-Through Rate on a
Floating Rate Certificate 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 Certificates will be rounded to the nearest
one-hundredth of a unit (with .005 of a unit being rounded upward).
 
     Interest on any Series (or Class within such Series) of Floating Rate
Certificates 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.
 
     Upon the request of the holder of any Floating Rate Certificate of a given
Series or Class, the Calculation Agent for such Series or Class will provide the
Pass-Through Rate then in effect and, if determined, the Pass-Through Rate that
will become effective on the next Interest Reset Date with respect to such

Floating Rate Certificate.
 
     (1) CD Rate Certificates. Each CD Rate Certificate will bear interest for
each Interest Reset Period at the Pass-Through Rate calculated with reference to
the CD Rate and the Spread or Spread Multiplier, if any, specified in such
Certificate and in the applicable Prospectus Supplement.
 
     Unless otherwise specified in the applicable Prospectus Supplement, the 'CD
Rate' for each Interest Reset Period shall be the rate as of the second Business
Day prior to the Interest Reset Date for such Interest Reset Period (a 'CD Rate
Determination Date') for negotiable certificates of deposit having the Index
Maturity designated in the applicable Prospectus Supplement as published in
H.15(519) under the heading 'CDs (Secondary Market).' In the event that such
rate is not published prior to 3:00 p.m., New York City time, on the Calculation
Date (as defined below) pertaining to such CD Rate Determination Date, then the
'CD Rate' for such Interest Reset Period will be the rate on such CD Rate
Determination Date for negotiable certificates of deposit of the Index Maturity
designated in the applicable Prospectus Supplement as published in Composite
Quotations under the heading 'Certificates of Deposit.' If by 3:00 p.m., New
York City time, on such Calculation Date such rate is not yet published in
either H.15(519) or Composite Quotations, then the 'CD Rate' for such Interest
Reset Period will be calculated by the Calculation Agent for such CD Rate
Certificate and will be the arithmetic mean of the secondary market offered
rates as of 10:00 a.m., New York City time, on such CD Rate 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 for such CD
Rate Certificate 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 Index Maturity
designated in the related Prospectus Supplement in a denomination of $5,000,000;
provided, however, that if the dealers selected as aforesaid by such Calculation
Agent are not quoting offered rates as mentioned in this sentence, the 'CD Rate'
for such Interest Reset Period will be the same as the CD Rate for the
immediately preceding Interest Reset Period (or, if there was no such Interest
Reset Period, the Initial Pass-Through Rate).
 
     The 'Calculation Date' pertaining to any CD Rate Determination Date shall
be the first to occur of (a) the tenth calendar day after such CD Rate
Determination Date or, if such day is not a Business Day, the next
 
                                       13
<PAGE>
succeeding Business Day or (b) the second Business Day preceding the date any
distribution of interest is required to be made following the applicable
Interest Reset Date.
 
     (2) Commercial Paper Rate Certificates. Each Commercial Paper Rate
Certificate will bear interest for each Interest Reset Period at the
Pass-Through Rate calculated with reference to the Commercial Paper Rate and the
Spread or Spread Multiplier, if any, specified in such Certificate and in the
applicable Prospectus Supplement.
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
'Commercial Paper Rate' for each Interest Reset Period will be determined by the

Calculation Agent for such Commercial Paper Rate Certificate as of the second
Business Day prior to the Interest Reset Date for such Interest Reset Period (a
'Commercial Paper Rate Determination Date') and shall be the Money Market Yield
(as defined below) on such Commercial Paper Rate Determination Date of the rate
for commercial paper having the Index Maturity specified in the applicable
Prospectus Supplement, as such rate shall be published in H.15(519) under the
heading 'Commercial Paper.' In the event that such rate is not published prior
to 3:00 p.m., New York City time, on the Calculation Date (as defined below)
pertaining to such Commercial Paper Rate Determination Date, then the
'Commercial Paper Rate' for such Interest Reset Period shall be the Money Market
Yield on such Commercial Paper Rate Determination Date of the rate for
commercial paper of the specified Index Maturity as published in Composite
Quotations under the heading 'Commercial Paper.' If by 3:00 p.m., New York City
time, on such Calculation Date such rate is not yet published in either
H.15(519) or Composite Quotations, then the 'Commercial Paper Rate' for such
Interest Reset Period shall 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 Commercial
Paper Rate Determination Date of three leading dealers of commercial paper in
The City of New York selected by the Calculation Agent for such Commercial Paper
Rate Certificate for commercial paper of the specified Index Maturity placed for
an industrial issuer whose bonds are rated 'AA' or the equivalent by a
nationally recognized rating agency; provided, however, that if the dealers
selected as aforesaid by such Calculation Agent are not quoting offered rates as
mentioned in this sentence, the 'Commercial Paper Rate' for such Interest Reset
Period will be the same as the Commercial Paper Rate for the immediately
preceding Interest Reset Period (or, if there was no such Interest Reset Period,
the Initial Pass-Through Rate).
 
     'Money Market Yield' shall 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 specified Index Maturity.
 
     The 'Calculation Date' pertaining to any Commercial Paper Rate
Determination Date shall be the first to occur of (a) the tenth calendar day
after such Commercial Paper Rate Determination Date or, if such day is not a
Business Day, the next succeeding Business Day or (b) the second Business Day
preceding the date any distribution of interest is required to be made following
the applicable Interest Reset Date.
 
     (3) Federal Funds Rate Certificates. Each Federal Funds Rate Certificate
will bear interest for each Interest Reset Period at the Pass-Through Rate
calculated with reference to the Federal Funds Rate and the Spread or Spread
Multiplier, if any, specified in such Certificate and in the applicable
Prospectus Supplement.
 
     Unless otherwise specified in the applicable Prospect Supplement, the
'Federal Funds Rate' for each Interest Reset Period shall be the effective rate

on the Interest Reset Date for such Interest Reset Period (a 'Federal Funds Rate
Determination Date') for Federal Funds as published in H.15(519) under the
heading 'Federal Funds (Effective).' In the event that such rate is not
published prior to 3:00 p.m., New York City time, on the Calculation Date (as
defined below) pertaining to such Federal Funds Rate Determination Date, the
'Federal Funds Rate' for such Interest Reset Period shall be the rate on such
Federal Funds Rate Determination Date as published in Composite Quotation under
the heading 'Federal Funds/Effective Rate.' If by 3:00 p.m., New York City time,
on such Calculation Date such rate is not yet published in either H.15(519) or
Composite Quotations, then the 'Federal Funds Rate' for such Interest Reset
Period shall be the rate on such Federal Funds Rate Determination Date made
publicly available by the Federal Reserve Bank of New York which is equivalent
to the rate which appears in H.15(519) under the heading 'Federal Funds
(Effective)'; provided, however, that if such rate is not made publicly
available by the Federal Reserve Bank of New York by 3:00 p.m., New York City
 
                                       14
<PAGE>
time, on such Calculation Date, the 'Federal Funds Rate' for such Interest Reset
Period will be the same as the Federal Funds Rate in effect for the immediately
preceding Interest Reset Period (or, if there was no such Interest Reset Period,
the Initial Pass-Through Rate). Unless otherwise specified in the applicable
Prospectus Supplement, in the case of a Federal Funds Rate Certificate that
resets daily, the Pass-Through Rate on such Certificate for the period from and
including a Monday to but excluding the succeeding Monday will be reset by the
Calculation Agent for such Certificate on such second Monday (or, if not a
Business Day, on the next succeeding Business Day) to a rate equal to the
average of the Federal Funds Rate in effect with respect to each such day in
such week.
 
     The 'Calculation Date' pertaining to any Federal Funds Rate Determination
Date shall be the next succeeding Business Day.
 
     (4) LIBOR Certificates. Each LIBOR Certificate will bear interest for each
Interest Reset Period at the Pass-Through Rate calculated with reference to
LIBOR and the Spread or Spread Multiplier, if any, specified in such Certificate
and in the applicable Prospectus Supplement.
 
     With respect to LIBOR indexed to the offered rate for U.S. dollar deposits,
unless otherwise specified in the applicable Prospectus Supplement, 'LIBOR' for
each Interest Reset Period will be determined by the Calculation Agent for any
LIBOR Certificate as follows:
 
          (i) On the second London Banking Day prior to the Interest Reset Date
     for such Interest Reset Period (a 'LIBOR Determination Date'), the
     Calculation Agent for such LIBOR Certificate will determine the arithmetic
     mean of the offered rates for deposits in U.S. dollars for the period of
     the Index Maturity specified in the applicable Prospectus Supplement,
     commencing on such Interest Reset Date, which appear on the Reuters Screen
     LIBO Page at approximately 11:00 a.m., London time, on such LIBOR
     Determination Date. 'Reuters Screen LIBO Page' means the display designated
     as page 'LIBOR' on the Reuters Monitor Money Rates Service (or such other
     page may replace the LIBO page on that service for the purpose of
     displaying London interbank offered rates of major banks). If at least two

     such offered rates appear on the Reuters Screen LIBO Page, 'LIBOR' for such
     Interest Reset Period will be the arithmetic mean of such offered rates as
     determined by the Calculation Agent for such LIBOR Certificate.
 
          (ii) If fewer than two offered rates appear on the Reuters Screen LIBO
     Page on such LIBOR Determination Date, the Calculation Agent for such LIBOR
     Certificate will request the principal London offices of each of four major
     banks in the London interbank market selected by such Calculation Agent to
     provide such Calculation Agent with their offered quotations for deposits
     in U.S. dollars for the period of the specified Index Maturity, commencing
     on such Interest Reset Date, to prime banks in the London interbank market
     at approximately 11:00 a.m., London time, on such LIBOR Determination Date
     and in a principal amount equal to an amount of not less than $1,000,000
     that is representative of a single transaction in such market at such time.
     If at least two such quotations are provided, 'LIBOR' for such Interest
     Reset Period will be the arithmetic mean of such quotations. If fewer than
     two such quotations are provided, 'LIBOR' for such Interest Reset Period
     will be the arithmetic mean of rates quoted by three major banks in The
     City of New York selected by the Calculation Agent for such LIBOR
     Certificate at approximately 11:00 a.m., New York City time, on such LIBOR
     Determination Date for loans in U.S. dollars to leading European banks, for
     the period of the specified Index Maturity, commencing on such Interest
     Reset Date, and in a principal amount equal to an amount of not less than
     $1,000,000 that is representative of a single transaction in such market at
     such time; provided, however, that if fewer than three banks selected as
     aforesaid by such Calculation Agent are quoting rates as mentioned in this
     sentence, 'LIBOR' for such Interest Reset Period will be the same as LIBOR
     for the immediately preceding Interest Reset Period (or, if there was no
     such Interest Reset Period, the Initial Pass-Through Rate).
 
     If LIBOR with respect to any LIBOR Certificate is indexed to the offered
rates for deposits in a currency other than U.S. dollars, the applicable
Prospectus Supplement will set forth the method for determining such rate.
 
      (5) Treasury Rate Certificates. Each Treasury Rate Certificate will bear
interest for each Interest Reset Period at the Pass-Through Rate calculated with
reference to the Treasury Rate and the Spread or Spread Multiplier, if any,
specified in such Certificate and in the applicable Prospectus Supplement.
 
                                       15
<PAGE>
     Unless otherwise specified in the applicable Prospectus Supplement, the
'Treasury Rate' for each Interest Reset Period will be the rate for the auction
held on the Treasury Rate Determination Date (as defined below) for such
Interest Reset Period of direct obligations of the United States ('Treasury
bills') having the Index Maturity specified in the applicable Prospectus
Supplement, as such rate shall be published in H.15(519) under the heading 'U.S.
Government Certificate-Treasury bills auction average (investment)' or, in the
event that such rate is not published prior to 3:00 p.m., New York City time, on
the Calculation Date (as defined below) pertaining to such Treasury Rate
Determination Date, the auction average rate (expressed as a bond equivalent on
the basis of a year of 365 or 366 days, as applicable, and applied on a daily
basis) on such Treasury Rate Determination Date 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 specified 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 Treasury Rate
Determination Date, then the 'Treasury Rate' for such Interest Reset Period
shall be calculated by the Calculation Agent for such Treasury Rate Certificate
and shall be a yield to maturity (expressed as a bond equivalent on the basis of
a year of 365 or 366 days, as applicable, and applied on a daily basis) of the
arithmetic mean of the secondary market bid rates, as of approximately 3:30
p.m., New York City time, on such Treasury Rate Determination Date, of three
leading primary United States government securities dealers selected by such
Calculation Agent for the issue of Treasury bills with a remaining maturity
closest to the specified Index Maturity; provided, however, that if the dealers
selected as aforesaid by such Calculation Agent are not quoting bid rates as
mentioned in this sentence, then the 'Treasury Rate' for such Interest Reset
Period will be the same as the Treasury Rate for the immediately preceding
Interest Reset Period (or, if there was no such Interest Reset Period, the
Initial Pass-Through Rate).
 
     The 'Treasury Rate Determination Date' for such Interest Reset Period will
be the day of the week in which the Interest Reset Date for such Interest Reset
Period falls on which Treasury bills would normally be auctioned. Treasury bills
are normally sold at auction on Monday of each week, unless that day is a legal
holiday, in which case the auction is normally held on the following Tuesday,
except that such auction may be held on the preceding Friday. If, as the result
of a legal holiday, an auction is so held on the preceding Friday, such Friday
will be the Treasury Rate Determination Date pertaining to the Interest Reset
Period commencing in the next succeeding week. Unless otherwise specified in the
applicable Prospectus Supplement, if an auction date shall fall on any day that
would otherwise be an Interest Reset Date for a Treasury Rate Certificate, then
such Interest Reset Date shall instead be the Business Day immediately following
such auction date.
 
     The 'Calculation Date' pertaining to any Treasury Rate Determination Date
shall be the first to occur of (a) the tenth calendar day after such Treasury
Rate Determination Date or, if such a day is not a Business Day, the next
succeeding Business Day or (b) the second Business Day preceding the date any
distribution of interest is required to be made following the applicable
Interest Reset Date.
 
PRINCIPAL OF THE CERTIFICATES
 
     Unless the related Prospectus Supplement provides otherwise, each
Certificate (other than certain Classes of Strip Certificates) will have a
'Certificate 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 flow on the Deposited Assets and other assets
included in the related Trust. Unless otherwise specified in the related
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 Certificate of the Class or Classes entitled thereto (in the manner and
priority specified in such Prospectus Supplement) until the aggregate
Certificate Principal Balance of such Class or Classes has been reduced to zero.
The outstanding Certificate Principal Balance of a Certificate 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 related
Prospectus Supplement provides otherwise, the initial aggregate Certificate
Principal Balance of all Classes of Certificates 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 Certificate Principal Balance
of a Series and each Class thereof will be specified in the related Prospectus
Supplement. Distributions of principal of any Class of Certificates will be made
on a pro rata basis among all the Certificates of such Class. Strip Certificates
with no Certificate Principal Balance will not receive distributions of
principal.
 
                                       16
<PAGE>
FOREIGN CURRENCY CERTIFICATES
 
     If the specified currency of any Certificate is not U.S. dollars (a
'Foreign Currency Certificate'), certain provisions with respect thereto will be
set forth in the related Prospectus Supplement which will specify the
denominations, the currency or currencies in which the principal and interest
with respect to such Certificate are to be paid and any other terms and
conditions relating to the non-U.S. dollar denominations or otherwise applicable
to the Certificates.
 
INDEXED CERTIFICATES
 
     From time to time, the Issuer may offer a Series of Certificates ('Indexed
Certificates'), the principal amount payable at the stated maturity date of
which (the 'Indexed Principal Amount') and/or interest with respect to which is
determined by reference to (i) the rate of exchange between the specified
currency for such Certificate and the other currency or composite currency (the
'Indexed Currency') specified therein; (ii) the difference in the price of a
specified commodity (the 'Indexed Commodity') on specified dates; (iii) the
difference in the level of a specified stock index (the 'Stock Index'), which
may be based on U.S. or foreign stocks, on specified dates; or (iv) such other
objective price or economic measure as are described in the related Prospectus
Supplement. The manner of determining the Indexed Principal Amount of an Indexed
Certificate, and historical and other information concerning the Indexed
Currency, Indexed Commodity, Stock Index or other price or economic measure used
in such determination, will be set forth in the related Prospectus Supplement,
together with any information concerning tax consequences to the Holders of such
Indexed Certificates.
 
     Except as otherwise specified in the related Prospectus Supplement,
interest on an Indexed Certificate will be payable based on the amount
designated in the related Prospectus Supplement as the 'Face Amount' of such
Indexed Certificate. The related Prospectus Supplement will describe whether the
principal amount of the related Indexed Certificate that would be payable upon
redemption or repayment prior to the stated maturity date will be the Face
Amount of such Indexed Certificate, the Indexed Principal Amount of such Indexed
Certificate at the time of redemption or repayment, or another amount described
in such Prospectus Supplement.
 
DUAL CURRENCY CERTIFICATES

 
     Certificates may be issued as dual currency certificates ('Dual Currency
Certificates'), in which case payments of principal and/or interest in respect
of Dual Currency Certificates will be made in such currencies, and rates of
exchange will be calculated upon such bases, as indicated in the Certificates
and described in the related Prospectus Supplement. Other material terms and
conditions relating to Dual Currency Certificates will be set forth in the
Certificates and the related Prospectus Supplement.
 
OPTIONAL EXCHANGE
 
     If a holder may exchange Certificates of any given Series for a pro rata
portion of the Deposited Assets, the applicable Prospectus Supplement will
designate such Series as an 'Exchangeable Series.' The terms upon which a holder
may exchange Certificates of any Exchangeable Series for a pro rata portion of
the Deposited Assets of the related Trust will be specified in the related
Prospectus Supplement; provided that any right of exchange shall be exercisable
only to the extent that such exchange would not be inconsistent with the
Depositor's and such Trust's continued satisfaction of the applicable
requirements for exemption under Rule 3a-7 under the Investment Company Act of
1940 and all applicable rules, regulations and interpretations thereunder. Such
terms may relate to, but are not limited to, the following:
 
          (a) a requirement that the exchanging holder tender to the Trustee
     Certificates of each Class within such Exchangeable Series;
 
          (b) a minimum Certificate Principal Balance or Notional Amount, as
     applicable, with respect to each Certificate being tendered for exchange;
 
          (c) a requirement that the Certificate Principal Balance or Notional
     Amount, as applicable, of each Certificate tendered for exchange be an
     integral multiple of an amount specified in the Prospectus Supplement;
 
                                       17
<PAGE>
          (d) specified dates during which a holder may effect such an exchange
     (each, an 'Optional Exchange Date');
 
          (e) limitations on the right of an exchanging holder to receive any
     benefit upon exchange from any Credit Support or other non-Underlying
     Securities deposited in the applicable Trust; and
 
          (f) adjustments to the value of the proceeds of any exchange based
     upon the required prepayment of future expense allocations and the
     establishment of a reserve for any anticipated Extraordinary Trust
     Expenses.
 
     Unless otherwise specified in the related Prospectus Supplement, in order
for a Certificate of a given Exchangeable Series (or Class within such
Exchangeable Series) to be exchanged by the applicable Certificateholder, the
trustee for such Certificate must receive, at least 30 (or such shorter period
acceptable to the Trustee) but not more than 45 days prior to an Optional
Exchange Date (i) such Certificate with the form entitled 'Option to Elect
Exchange' on the reverse thereof duly completed, or (ii) in the case of

Registered Certificates, a telegram, telex, facsimile transmission or letter
from a member of a national securities exchange or the National Association of
Securities Dealers, Inc., the Depository (in accordance with its normal
procedures) or a commercial bank or trust company in the United States setting
forth the name of the holder of such Registered Certificate, the Certificate
Principal Balance or Notional Amount of such Registered Certificate to be
exchanged, the certificate number or a description of the tenor and terms of
such Registration Certificate, a statement that the option to elect exchange is
being exercised thereby and a guarantee that the Registered Certificate to be
exchanged with the form entitled 'Option to Elect Exchange' on the reverse of
the Registered Certificate duly completed will be received by such Trustee not
later than five Business Days after the date of such telegram, telex, facsimile
transmission or letter. If the procedure described in clause (ii) of the
preceding sentence is followed, then such Registered Certificate and form duly
completed must be received by such Trustee by such fifth Business Day. Any
tender of a Certificate by the holder for exchange shall be irrevocable. The
exchange option may be exercised by the holder of a Certificate for less than
the entire Certificate Principal Balance of such Certificate provided that the
Certificate Principal Balance or Notional Amount, as applicable, of such
Certificate remaining outstanding after redemption is an authorized denomination
and all other exchange requirements set forth in the related Prospectus
Supplement are satisfied. Upon such partial exchange, such Certificate shall be
canceled and a new Certificate or Certificates for the remaining Certificate
Principal Balance thereof shall be issued (which, in the case of any Registered
Certificate, shall be in the name of the holder of such exchanged Certificate).
 
     Unless otherwise specified in the applicable Prospectus Supplement, because
initially and until Definitive Certificates are issued each Certificate will be
represented by a Global Security, the Depository's nominee will be the
Certificateholder of such Certificate and therefore will be the only entity that
can exercise a right of exchange. In order to ensure that the Depository's
nominee will timely exercise a right of exchange with respect to a particular
Certificate, the beneficial owner of such Certificate must instruct the broker
or other direct or indirect participant through which it holds an interest in
such Certificate to notify the Depository of its desire to exercise a right of
exchange. Different firms have different cut-off times for accepting
instructions from their customers and, accordingly, each beneficial owner should
consult the broker or other direct or indirect participant through which it
holds an interest in a Certificate in order to ascertain the cut-off time by
which such an instruction must be given in order for timely notice to be
delivered to the Depository.
 
     Unless otherwise provided in the applicable Prospectus Supplement, upon the
satisfaction of the foregoing conditions and any applicable conditions with
respect to the related Deposited Assets, as described in such Prospectus
Supplement, the applicable Certificateholder will be entitled to receive a
distribution of a pro rata share of the Deposited Assets related to the
Exchangeable Series (and Class within such Exchangeable Series) of the
Certificate being exchanged, in the manner and to the extent described to such
Prospectus Supplement. Alternatively, to the extent so specified in the
applicable Prospectus Supplement, the applicable Certificateholder, upon
satisfaction of such conditions, may direct the related Trustee to sell, on
behalf of such Certificateholder, such pro rata share of the Deposited Assets,
in which event the Certificateholder shall be entitled to receive the net

proceeds of such sale, less any costs and expenses incurred by such Trustee in
facilitating such sale, subject to any additional adjustments set forth in the
Prospectus Supplement.
 
                                       18

GLOBAL SECURITIES
 
     Unless otherwise specified in the applicable Prospectus Supplement, all
Certificates of a given Series (or, if more than one Class exists, any given
Class within that Series) will, upon issuance, be represented by one or more
Global Securities that will be deposited with, or on behalf of, The Depository
Trust Company, New York (for Registered Certificates denominated and payable in
U.S. dollars), or such other depositary identified in the related Prospectus
Supplement (the 'Depository'), and registered in the name of a nominee of the
Depository. Global Securities may be issued in either registered or bearer form
and in either temporary or definitive form. See 'Limitations on Issuance of
Bearer Certificates' for provisions applicable to Certificates issued in bearer
form. Unless and until it is exchanged in whole or in part for the individual
Certificates represented thereby (each a 'Definitive Certificate'), a Global
Security may not be transferred except as a whole by the Depository for such
Global Security to a nominee of such Depository or by a nominee of such
Depository to such Depository or another nominee of such Depository or by such
Depository or any such nominee to a successor of such Depository or a nominee of
such successor (Sections 5.02 and 5.04).
 
     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
Depository ('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 Depository's participants
include securities brokers and dealers (including the Offering Agent), banks,
trust companies, clearing corporations, and certain other organizations, some of
whom (and/or their representatives) own such Depository. Access to such
Depository's book-entry system is also available to others, such as banks,
brokers, dealers and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly. The Depository
Trust Company has confirmed to the Depositor that it intends to follow such
procedures.
 
     Upon the issuance of a Global Security, the Depository for such Global
Security will credit, on its book-entry registration and transfer system, the
respective principal amounts of the individual Certificates represented by such
Global Security to the accounts of its participants. The accounts to be
accredited shall be designated by the underwriters of such Certificates, or, if
such Certificates 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 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 Depository for such Global
Security or by participants or Persons 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 Depository for a Global Security, or its nominee, is the
owner of such Global Security, such Depository or such nominee, as the case may
be, will be considered the sole Certificateholder of the individual Certificates
represented by such Global Security for all purposes under the Trust Agreement
governing such Certificates. Except as set forth below, owners of beneficial
interests in a Global Security will not be entitled to have any of the
individual Certificates represented by such Global Security registered in their
names, will not receive or be entitled to receive physical delivery of any such
Certificates and will not be considered the Certificateholders thereof under the
Trust Agreement governing such Certificates. Because the Depository can only act
on behalf of its participants, the ability of a holder of any Certificate to
pledge that Certificate to persons or entities that do not participate in the
Depository's system, or to otherwise act with respect to such Certificate, may
be limited due to the lack of a physical certificate for such Certificate.
 
     Subject to the restrictions discussed under 'Limitations on Issuance of
Bearer Certificates' below, distributions of principal of (and premium, if any)
and any interest on individual Certificates represented by a Global Security
will be made to the Depository or its nominee, as the case may be, as the
Certificateholder of such Global Security. None of the Depositor, the
Administrative Agent, if any, the Trustee for such Certificates, any Paying
Agent or the Certificate Registrar for such Certificates will have
responsibility or liability for any
 
                                       19
<PAGE>
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 Depository for Certificates of a given Class
and Series, upon receipt of any distribution of principal, premium or interest
in respect of a definitive Global Security representing any of such
Certificates, 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 Depository. The
Depositor also expects that payments by participants to owners of beneficial
interests in such Global Security held through such participants will be
governed by standing instructions and customary practices, as is now the case
with securities held for the accounts of customers in bearer form or registered
in 'street name,' and will be the responsibility of such participants. Receipt
by owners of beneficial interests in a temporary Global Security of payments of
principal, premium or interest in respect thereof will be subject to the
restrictions discussed below under 'Limitations on Issuance of Bearer
Certificates' below.
 

     If the Depository for Certificates of a given Class of any Series is at any
time unwilling or unable to continue as depositary and a successor depositary is
not appointed by the Depositor within ninety (90) days, the Depositor will issue
individual Definitive Certificates in exchange for the Global Security or
Securities representing such Certificates. In addition, the Depositor may at any
time and in its sole discretion determine not to have any Certificates of a
given Class represented by one or more Global Securities and, in such event,
will issue Definitive Certificates of such Class in exchange for the Global
Security or Securities representing such Certificates. Further, if the Depositor
so specifies with respect to the Certificates of a given Class, an owner of a
beneficial interest in a Global Security representing Certificates of such Class
may, on terms acceptable to the Depositor and the Depository for such Global
Security, receive individual Definitive Certificates 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
Certificates of the Class represented by such Global Security equal in principal
amount to such beneficial interest and to have such Definitive Certificates
registered in its name (if the Certificates of such Class are issuable as
Registered Certificates). Individual Definitive Certificates of such Class so
issued will be issued (a) as Registered Certificates in denominations, unless
otherwise specified by the Depositor, of $1,000 and integral multiples thereof
if the Certificates of such Class are issuable as Registered Certificates, (b)
as Bearer Certificates in the denomination or denominations specified by the
Depositor if the Certificates of such Class are issuable as Bearer Certificates
or (c) as either Registered or Bearer Certificates, if the Certificates of such
Class are issuable in either form (Section 5.03). See, however, 'Limitations on
Issuance of Bearer Certificates' below for a description of certain restrictions
on the issuance of individual Bearer Certificates in exchange for beneficial
interests in a Global Security.
 
     The applicable Prospectus Supplement will set forth any specific terms of
the depositary arrangement with respect to any Class or Series of Certificates
being offered thereby to the extent not set forth or different from the
description set forth above.

               DESCRIPTION OF DEPOSITED ASSETS AND CREDIT SUPPORT
 
GENERAL
 
     Each Certificate of each Series (or if more than one Class exists, each
Class (whether or not each such Class is offered hereby) within such Series)
will represent an ownership interest specified for such Series (or Class) of
Certificates in a designated, publicly issued, fixed income debt security or a
pool of such debt securities (the 'Underlying Securities'), purchased by the
Depositor (or an affiliate thereof) in the secondary market and assigned to a
Trust as described in the applicable Prospectus Supplement. The Underlying
Securities will represent direct obligations of one or more corporations,
banking organizations or insurance companies organized under the laws of the
United States or any state, which are subject to the informational requirements
of the Exchange Act and which, in accordance therewith, file reports and other
information with the Commission (with respect to each Underlying Security, an
'Underlying Securities Issuer').

 
     This Prospectus relates only to the Certificates offered hereby and does
not relate to the Underlying Securities. The following description of the
Underlying Securities is intended only to summarize certain characteristics of
the Underlying Securities the Depositor is permitted to deposit in a Trust and
does not purport to be a complete description of any Underlying Security
Prospectus and Underlying Security Indenture (as defined below).
 
UNDERLYING SECURITIES INDENTURE
 
     General.  Unless otherwise specified in the related Prospectus Supplement,
each Underlying Security will have been issued pursuant to an agreement (each, a
'Underlying Securities Indenture') between the Underlying Securities Issuer and
a trustee (the 'Underlying Securities Trustee'). Unless otherwise specified, the
Underlying Securities Indenture and the Underlying Securities Trustee will be
qualified under the Trust Indenture Act of 1939 (the 'Trust Indenture Act') and
the Underlying Securities 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 any
subsidiary's, ability to: (i) consolidate, merge, or transfer or lease assets;
(ii) incur or suffer to exist any lien, charge, or encumbrance upon any 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; (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. 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 Underlying Securities 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 or additional covenants not discussed herein.
To the extent that the Underlying Securities are investment grade debt, they are
unlikely to contain significant restrictive covenants, although certain
non-investment grade debt may not be subject to restrictive covenants either.
There can be no assurance that any such provision will protect the Trust as a
holder of the Underlying Securities against losses. The Prospectus Supplement
used to offer any Series of Certificates will describe material covenants in
relation to any Concentrated Underlying Security and, as applicable, will
describe material covenants which are common to any pool of Underlying
Securities.
 
     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
 
                                       21
<PAGE>
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 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 issuer or the
acceleration by or on behalf of the holders thereof of such securities; and (iv)
certain events of insolvency or bankruptcy with respect to the Underlying
Securities Issuer.
 
     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
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 Underlying Securities Indenture may include some, all or none of the
foregoing provisions or variations thereof or additional events of default not
discussed herein. The Prospectus Supplement with respect to any Series of
Certificates will describe the events of default under the Underlying Securities
Indenture with respect to any Concentrated Underlying Security ('Underlying
Security Events of Default') 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. If a 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 a Underlying Security and any accrued
and unpaid interest thereon to be due and payable, the Certificateholders'
objectives may differ from those of holders of other securities of the same
series and class as any Underlying Security ('Outstanding Debt Securities') in

determining whether to declare the acceleration of the Underlying Securities.
 
     Subordination.  As set forth 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
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 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 amounts in respect of such securities. Reference
is made to the Prospectus Supplement used to offer any Series of Certificates
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 offered and sold, an
issuer of secured obligations generally has the right to remain in possession
and retain exclusive control of the collateral securing a security 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
 
                                       22
<PAGE>
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 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 Underlying Securities Indenture with respect to any Secured Underlying

Security may include, some, all or none of the foregoing provisions or
variations thereof. The Prospectus Supplement used to offer any Series of
Certificates that includes Concentrated Underlying Securities which are Secured
Underlying Securities will describe the 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 general
information with respect to such security provisions and the collateral.
 
PRINCIPAL ECONOMIC TERMS OF UNDERLYING SECURITIES
 
     Reference is made to the applicable Prospectus Supplement with respect to
each Series of Certificates 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 obligations of the Underlying Securities Issuer; (iii) whether any of the
obligations are secured or unsecured and the nature of any collateral; (iv) the
limit, if any, upon the aggregate principal amount of such debt securities; (v)
the dates on which, or the range of dates within which, the principal of (and
premium, if any, on) such debt 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 ('Underlying Securities Interest
Accrual Periods'); and the dates on which such interest will be payable
('Underlying Securities Payment Dates'); (vii) the obligation, if any, of the
Underlying Securities Issuer to redeem the Outstanding Debt Securities pursuant
to any sinking fund or analogous 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 debt 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 debt 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 foreign or composite
currency in which such debt securities are denominated, or in which payment of
the principal of (and premium, if any) or any interest on such Underlying
Securities will be made (the 'Underlying Securities Currency'), 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, and (xiii) any
other material terms of such Underlying Securities.
 
     With respect to a Trust comprised of a pool of Underlying Securities, the
related 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 (ii), (iii), (v), (vi), (vii),
(viii) and (ix) of the preceding paragraph and any other material terms
regarding such pool of securities.
 
     In addition to the foregoing, with respect to each Concentrated Underlying

Security the applicable Prospectus Supplement will disclose the identity of the
applicable obligor and the Underlying Securities Trustee, and will describe the
existence and type of certain information that is made publicly available by
each obligor regarding such Underlying Security or Underlying Securities and
will disclose where and how prospective purchasers of the Certificates may
obtain such publicly available information with respect to each such obligor.
 
                                       23
<PAGE>
Such publicly available information will typically consist of the quarterly and
annual reports filed under the Exchange Act by such issuer with, and which are
available from, the Commission.
 
     If an issuer of Concentrated Underlying Securities ceases to file periodic
reports under the Exchange Act, the Depositor, on behalf of the Trust, will
continue to be subject to the reporting requirements of the Exchange Act but
certain information with respect to such issuer may be unavailable.
 
OTHER DEPOSITED ASSETS
 
     In addition to the Underlying Securities, the Depositor may also deposit
into a given Trust, or the Trustee on behalf of the Certificateholders of a
Trust may enter into an agreement constituting or providing for the purchase of,
to the extent described in the related Prospectus Supplement, certain assets
related or incidental to one or more of such Underlying Securities or to some
other asset deposited in the Trust, including hedging contracts and other
similar arrangements (such as puts, calls, interest rate swaps, currency swaps,
floors, caps and collars, 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 (all such assets for any given Series, together
with the related Underlying Securities, the 'Deposited Assets'). The applicable
Prospectus Supplement will, to the extent appropriate, contain analogous
disclosure with respect to the foregoing assets as referred to above with
respect to the Underlying Securities.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Deposited Assets for a given Series of Certificates and the related Trust will
not constitute Deposited Assets for any other Series of Certificates and the
related Trust and the Certificates of each Class of a given Series 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.
 
CREDIT SUPPORT
 
     As specified in the applicable Prospectus Supplement for a given Series of
Certificates, the Trust for any Series of Certificates may include, or the
Certificateholders 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
Certificate contains, or the Certificateholders of such Certificates 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
Certificateholders of any given Class within a Series of Certificates to receive
collections from the Trust for such Series and any Credit Support obtained for
the benefit of the Certificateholders of such Series (or Classes within such
Series) may be subordinated to the rights of the Certificateholders of one or
more other Classes of such Series to the extent described in the related
Prospectus Supplement. Such subordination accordingly provides some additional
credit support to those Certificateholders of those other Classes. For example,
if losses are realized during a given period on the Deposited Assets relating to
a Series of Certificates such that the collections received thereon are
insufficient to make all distributions on the Certificates of such Series, those
realized losses would be allocated to the Certificateholders of any Class of any
such Series that is subordinated to another Class, to the extent and in the
manner provided in the related Prospectus Supplement. In addition, if so
provided in the applicable Prospectus Supplement, certain amounts otherwise
payable to Certificateholders 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 related Prospectus Supplement.
 
                                       24
<PAGE>
     If so provided in the related Prospectus Supplement, the Credit Support for
any Series or Class of Certificates 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 Certificateholders of such Class or as otherwise specified in the related
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 Certificates of such Series.
 
     Letter of Credit; Surety Bond.  The Certificateholders of any Series (or
Class or group of Classes of Certificates 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 related 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 the
related 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 related 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 Certificates, in the manner and priority specified
in the applicable Prospectus Supplement. Amounts may be distributed to
Certificateholders 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
related 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 named in the related Prospectus
Supplement.
 
COLLECTIONS
 
     The Trust Agreement will establish procedures by which the Trustee or such
other person specified in the Prospectus Supplement is obligated, for the
benefit of the Certificateholders of each Series of Certificates, 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 account maintained or controlled by the

applicable Trustee for the benefit of such Series (each a 'Certificate
Account'). An Administrative Agent, if any is appointed pursuant to the
applicable Prospectus Statement, will direct the Trustee,
 
                                       25
<PAGE>
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 Certificates of such Series
(and Classes within such Series), all in the manner and priorities described in
the related Prospectus Supplement. The applicable Prospectus Supplement will
specify the collection periods, if applicable, and Distribution Dates for a
given Series of Certificates 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 Certificateholders for a particular Series
or Class of Certificates 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 Certificates. 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 Certificates, 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 Certificates
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 certain provisions of the Trust Agreement and the
Certificates 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 Trust
Agreement. Wherever particular sections or defined terms of the Trust Agreement
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 Certificates, the Depositor will
cause the Underlying Securities to be included in the related Trust, and any
other Deposited Asset specified in the Prospectus Supplement, to be assigned to
the related Trustee, together with all principal, premium (if any) and interest
received by or on behalf of the Depositor on or with respect to such 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 (Section 2.01). The
Trustee will, concurrently with such assignment, deliver the Certificates to the
Depositor in exchange for certain assets to be deposited in the Trust (Section
2.06). Each Deposited Asset will be identified in a schedule appearing as an
exhibit to the Trust Agreement. Such schedule will include certain statistical
information with respect to each Underlying Security and each other Deposited
Asset as of the Cut-off Date, and in the event any Underlying Security
represents ten percent or more of the total Underlying Securities with respect
to any Series of Certificates, such schedule will include, to the extent
applicable, information regarding the payment terms thereof, the Retained
Interest, if any, with respect thereto, the maturity or terms thereof, the
rating, if any, thereof and certain other 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 review such documents
upon receipt thereof or within such period as is permitted in the Prospectus
Supplement, and the Trustee (or such custodian) will hold such documents in
trust for the benefit of the Certificateholders (Sections 2.01 and 2.02).
 
     With respect to certain types of Deposited Assets specified in the
applicable Prospectus Supplement if and to the extent provided therein, if any
such document is found to be missing or defective in any material respect, the
Trustee (or such custodian) shall immediately notify the Administrative Agent,
if any, and the Depositor, and the Administrative Agent, if any, and otherwise
the Trustee shall immediately notify the relevant person who sold the applicable
Deposited Asset to the Depositor (a 'Deposited Asset Provider'). If and to the
extent specified in the applicable Prospectus Supplement, if the Deposited Asset
Provider cannot cure such omission or defect within 60 days after receipt of
such notice, the Deposited Asset Provider will be obligated, within 90 days of
receipt of such notice, to repurchase the related Deposited Asset from the
Trustee at the Purchase Price (as defined below) or provide a substitute for
such Deposited Asset. There can be no assurance that a Deposited Asset Provider
will fulfill this repurchase or substitution obligation. Although the
Administrative Agent, if any, or otherwise the Trustee is obligated to use its
best efforts to enforce such obligation, neither such Administrative Agent nor
the Depositor will be obligated to repurchase or substitute for such Deposited
Asset if the Deposited Asset Provider defaults on its obligation. Unless
otherwise specified in the related Prospectus Supplement, when applicable, this
repurchase or substitution obligation constitutes the sole remedy available to
the Certificateholders or the Trustee for omission of, or a material defect in,
or failure to provide, a constituent document (Section 2.03).
 
     Each of the Depositor and the Administrative Agent, if any, 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 or any such Administrative
Agent, as the case may be, which materially and adversely affects the interests
of the Certificateholders, the Depositor or any such Administrative Agent,
respectively, will be obligated to cure the breach in all material respects
(Sections 2.04 and 2.05).
 
                                       27

COLLECTION AND OTHER ADMINISTRATIVE PROCEDURES
 
     General.  With respect to any Series of Certificates 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 (collectively, the 'Credit Support Instruments') and provided
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.  Any Trustee or Administrative Agent may delegate its
obligations in respect of the Deposited Assets to third parties they deem
qualified to perform such obligations (each, a 'Sub-Administrative Agent'), but
the Trustee or Administrative Agent will remain obligated with respect to such
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 (as defined below).
 
     The agreement between any Administrative Agent or Trustee and a
Sub-Administrative Agent (a 'Sub-Administration Agreement') will be consistent
with the terms of the Trust Agreement and such assignment to the
Sub-Administrator by itself will not result in a withdrawal or downgrading of
the rating of any Class of Certificates issued pursuant to the Trust Agreement.
With respect to any Sub-Administrative 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
Certificates is issued will provide that, if for any reason such Administrative
Agent for such Series of Certificates 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 Administrative Agent or Trustee, as applicable, will be solely liable
for all fees owed by it to any Sub-Administrative Agent, irrespective of whether
the compensation of the Administrative Agent or Trustee, as applicable, pursuant
to the Trust Agreement with respect to the particular Series of Certificates 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
related Prospectus Supplement. Each Sub-Administrative Agent will be reimbursed
by the Administrative Agent, if any, or otherwise the Trustee for certain
expenditures which it makes, generally to the same extent the Administrative
Agent or Trustee, as applicable, would be reimbursed under the terms of the
Trust Agreement relating to such Series. See '--Retained Interest;
Administrative Agent 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 Certificateholders 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 Certificate Account for the related Trust,
subject to withdrawal as described above.
 
     Unless otherwise provided in the applicable Prospectus Supplement, if
recovery on a defaulted Deposited Asset under any related Credit Support
Instrument is not available, 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 the
 
                                       28
<PAGE>
defaulted Deposited Asset (Section 3.12), provided that, except as otherwise
expressly provided in the applicable Prospectus Supplement, it shall not be
required to expend or risk its own funds or otherwise incur personal 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 thereon at the applicable interest rate
and (iii) the aggregate amount of expenses incurred by the Administrative Agent
and the Trustee, as applicable, in connection with such proceedings to the
extent reimbursable from the assets of the Trust under the Trust Agreement, the
Trust will realize a loss in the amount of such difference (Section 3.12). Only
if and to the extent provided in the applicable Prospectus Supplement, the
Administrative Agent or Trustee, as so provided, may be entitled to withdraw or
cause to be withdrawn from the related Certificate Account out of the net
proceeds recovered on any defaulted Deposited Asset, prior to the distribution
of such proceeds to Certificateholders, 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; ADMINISTRATIVE AGENT COMPENSATION AND PAYMENT OF EXPENSES
 

     The Prospectus Supplement for a Series of Certificates 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 interest therein. 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 Certificate
Account or become a part of the related Trust. Unless otherwise provided in the
applicable Prospectus Supplement, any partial recovery of interest on a
Deposited Asset, after deduction of all applicable administration fees, will be
allocated between the Retained Interest (if any) and interest distributions to
Certificateholders on a pari passu basis.
 
     The applicable Prospectus Supplement will specify the Administrative
Agent's, if any, and the Trustee's compensation, and the source, manner and
priority of payment thereof, with respect to a given Series of Certificates.
 
     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 Certificateholders, and
payment of any other expenses described in the related Prospectus Supplement
(Section 3.14).
 
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 Certificateholders of the related Series of Certificates. 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 Certificate 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 fees 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
Certificates entitled thereto, rather than to guarantee or insure against
losses. Unless otherwise provided in the related 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

 
                                       29
<PAGE>
any Deposited Assets, 'Related Proceeds'); provided, however, that any such
advance will be reimbursable from any amounts in the Certificate Accounts for
such Series to the extent that such Administrative Agent shall determine, in its
sole judgment, that such advance (a 'Nonrecoverable Advance') is not ultimately
recoverable from Related Proceeds. If advances have been made by such
Administrative Agent from excess funds in the Certificate Account for any
Series, such Administrative Agent will replace such funds in such Certificate
Account on any future Distribution Date to the extent that funds in such
Certificate Account on such Distribution Date are less than payments required to
be made to Certificateholders on such date (Section 4.03). If so specified in
the related 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
related Prospectus Supplement.
 
CERTAIN MATTERS REGARDING THE ADMINISTRATIVE AGENT AND THE DEPOSITOR
 
     An Administrative Agent, if any, for each Series of Certificates under the
Trust Agreement will be named in the related Prospectus Supplement. The entity
serving as Administrative Agent for any such Series may be the Trustee, the
Depositor, as affiliate of either thereof, the Deposited Asset Provider or any
third party and may have other normal 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 Certificates 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 Certificates 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 (Section 6.04).
 
     The Trust Agreement will further provide that neither such an
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 Certificateholders 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 company 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 Certificates, 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 Certificateholders thereunder (Section 6.03). 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 or 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 Certificates of any given Series
(Section 6.02).

ADMINISTRATIVE AGENT TERMINATION EVENTS; RIGHTS UPON ADMINISTRATIVE AGENT
TERMINATION EVENT
 
     Unless otherwise provided in the related Prospectus Supplement,
'Administrative Agent Termination Events' under the Trust Agreement with respect
to any given Series of Certificates will consists 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 Certificates 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
Certificates 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 pay its
obligations (Section 7.01). Any additional Administrative Agent Termination
Events with respect to any given Series of Certificates 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 Certificates 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 Certificates of a given Series, the specified percentage

(computed on the basis of outstanding Certificate Principal Balance or Notional
Amount, as applicable) of Certificates 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 Certificate will be the portion of the voting rights of
all the Certificates in the related Series allocated in the manner described in
the related Prospectus Supplement (Article I).
 
     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 Certificates remains unremedied, the Depositor or
the Trustee may, and at the direction of holders of such Certificates evidencing
not less than the 'Required Percentage--Administrative Agent Termination' 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 Certificates evidencing not less than the 'Required Percentage--
Administrative Agent Termination' of the Voting Rights, it will appoint, or
petition a court of competent jurisdiction for the appointment of, an
administration 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
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 (Sections 7.01 and 7.02).
 
     No Certificateholder 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
Certificates evidencing not less than the 'Required Percentage-- Remedies' 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 (Section 10.03). The Trustee, however, is under
no obligation to exercise any of the trusts or
 
                                       31
<PAGE>
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 Certificates covered by the Trust Agreement, unless such

Certificateholders have offered to the Trustee reasonable security or indemnity
against the costs, expenses and liabilities which may be incurred therein or
thereby (Section 8.02).
 
MODIFICATION AND WAIVER
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
Trust Agreement for each Series of Trust Certificates may be amended by the
Depositor and the Trustee with respect to such Series, without notice to or
consent of the Certificateholders, for certain purposes including (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 add or supplement any Credit Support for the benefit of any
Certificateholders (provided that if any such addition affects any series or
class of Certificateholders differently than any other series or class of
Certificateholders, 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 Certificateholders), (iv) to add to the covenants, restrictions or
obligations of the Depositor, the Administrative Agent, if any, or the Trustee
for the benefit of the Certificateholders, (v) 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 Certificate for tax purposes and (y) the Trustee
has received written confirmation from each Rating Agency rating such
Certificates that such amendment will not cause such Rating Agency to reduce or
withdraw the then current rating thereof, or (vi) 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 Certificates
evidencing not less than the 'Required Percentage--Amendment' of the Voting
Rights of those Certificates 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 Certificateholders; 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-- Amendment' specified in the related series supplement to
the Trust Agreement shall include an additional specified percentage of the
Certificates of such Series or Class.
 
     Except as otherwise set forth in the applicable Prospectus Supplement, no
such modification or amendment may, however, (i) reduce in any manner the amount
of or alter the timing of, distributions or payments which are required to be
made on any Certificate without the consent of the holder of such Certificate or
(ii) reduce the aforesaid Required Percentage of Voting Rights required for the
consent to any such amendment without the consent of the holders of all
Certificates covered by the Trust Agreement then outstanding.
 
     Unless otherwise specified in the applicable Prospectus Supplement, holders
of Certificates evidencing not less than the 'Required Percentage--Waiver' of
the Voting Rights of a given Series may, on behalf of all Certificateholders of
that Series, (i) waive, insofar as that Series is concerned, compliance by the

Depositor, the Trustee or the Administrative Agent, if any, 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 Certificates 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 Certificate 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 Certificate affected thereby (Section 7.04).
 
REPORTS TO CERTIFICATEHOLDERS; NOTICES
 
     Reports to Certificateholders.  Unless otherwise provided in the applicable
Prospectus Supplement, with each distribution to Certificateholders of any Class
of Certificates of a given Series, the Administrative Agent or the Trustee, as
provided in the related Prospectus Supplement, will forward or cause to be
forwarded to each such
 
                                       32
<PAGE>
Certificateholder, to the Depositor and to such other parties as may be
specified in the Trust Agreement, a statement setting forth:
 
          (i) the amount of such distribution to Certificateholders of such
     Class allocable to principal of or interest or premium, if any, on the
     Certificates of such Class; and the amount of aggregate unpaid interest as
     of such Distribution Date;
 
          (ii) in the case of Certificates with a variable Pass-Through Rate,
     the Pass-Through Rate applicable to such Distribution Date, as calculated
     in accordance with the method specified herein and in the related
     Prospectus Supplement;
 
          (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
     Certificateholders 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 aggregate stated principal amount or, if applicable, notional
     principal amount of the Deposited Assets and the current interest rate
     thereon at the close of business on such Distribution Date;
 
          (vi) the aggregate Certificate Principal Balance or aggregate Notional
     Amount, if applicable, of each Class of Certificates (including any Class
     of Certificates not offered hereby) at the close of business on such
     Distribution Date, separately identifying any reduction in such aggregate
     Certificate Principal Balance or aggregate Notional Amount due to the
     allocation of any Realized Losses or otherwise; and
 

          (vii) as to any Series (or Class within such Series) for which Credit
     Support has been obtained, the amount of coverage of each element of Credit
     Support included therein as of the close of business on such Distribution
     Date.
 
     In the case of information furnished pursuant to subclauses (i) and (iii)
above, the amounts shall be expressed as a U.S. dollar amount (or equivalent
thereof in any other Specified Currency) per minimum denomination of
Certificates or for such other specified portion thereof. Within a reasonable
period of time after the end of each calendar year, the Administrative Agent or
the Trustee, as provided in the related Prospectus Supplement, shall furnish to
each person who at any time during the calendar year was a Certificateholder a
statement containing the information set forth in subclauses (i) and (iii)
above, aggregated for such calendar year or the applicable portion thereof
during which such person was a Certificateholder. Such obligation of the
Administrative Agent or the Trustee, as applicable, shall be deemed to have been
satisfied to the extent that substantially comparable information shall be
provided by the Administrative Agent or the Trustee, as applicable, pursuant to
any requirements of the Code as are from time to time in effect (Section 4.02).
 
     Notices.  Unless otherwise provided in the applicable Prospectus
Supplement, any notice required to be given to a holder of a Registered
Certificate will be mailed to the last address of such holder set forth in the
applicable Certificate Register. Any notice required to be given to a holder of
a Bearer Certificate will be published in a daily morning newspaper of general
circulation in the city or cities specified in the Prospectus Supplement
relating to such Bearer Certificate.
 
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
 
                                       33
<PAGE>
such exceptions as such firm shall believe to be immaterial and such other
exceptions and qualifications as shall be set forth in such report (Section
3.16).
 
     The Trust Agreement will also provide for delivery to the Depositor, the
Administrative Agent, if any, and the Trustee on behalf of the
Certificateholders, 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 Certificates (Section 3.15).
 
     Copies of the annual accountants' statement, if any, and the statement of
officers of the Trustee may be obtained by Certificateholders without charge
upon written request to either the Administrative Agent or the Trustee, as
applicable, at the address set forth in the related Prospectus Supplement.
 
REPLACEMENT CERTIFICATES
 
     Unless otherwise provided in the applicable Prospectus Supplement, if a
Certificate is mutilated, destroyed, lost or stolen, it may be replaced at the
corporate trust office or agency of the applicable Trustee in the City and State
of New York (in the case of Registered Certificates) or at the principal London
office of the applicable Trustee (in the case of Bearer Certificates), or such
other location as may be specified in the applicable Prospectus Supplement, upon
payment by the holder of such expenses as may be incurred by the applicable
Trustee in connection therewith and the furnishing of such evidence and
indemnity as such Trustee may require. Mutilated Certificates must be
surrendered before new Certificates will be issued (Section 5.05).
 
TERMINATION
 
     The obligations created by the Trust Agreement for each Series of
Certificates will terminate upon the payment to Certificateholders of that
Series of all amounts held in the related Certificate Account or by an
Administrative Agent, if any, and required to be paid to them pursuant to the
Trust Agreement following the earlier of (i) the final payment or other
liquidation of the last Deposited Asset subject thereto or the disposition of
all property acquired upon foreclosure or liquidation of any such Deposited
Asset and (ii) the purchase of all the assets of the Trust by the party entitled
to effect such termination, under the circumstances and in the manner set forth
in the related Prospectus Supplement. In no event, however, will any trust
created by the Trust Agreement continue beyond the respective date specified in
the related Prospectus Supplement. Written notice of termination of the
obligations with respect to the related Series of Certificates under the Trust
Agreement will be provided as set forth above under '--Reports to
Certificateholders; Notices--Notices,' and the final distribution will be made
only upon surrender and cancellation of the Certificates at an office or agency
appointed by the Trustee which will be specified in the notice of termination
(Section 9.01).
 
     Any such purchase of Deposited Assets and property acquired in respect of
Deposited Assets evidenced by a Series of Certificates 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 Certificates 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 for such Series
at the time of purchase being less than the percentage of the aggregate

principal balance of the Deposited Assets at the Cut-off Date for that Series
specified in the related Prospectus Supplement (Section 9.01).
 
DUTIES OF THE TRUSTEE
 
     The Trustee makes no representations as to the validity or sufficiency of
the Trust Agreement, the Certificates 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 Certificates or the Deposited Assets,
or deposited into or withdrawn from the related Certificate Account or any other
account by or on behalf of such Administrative Agent (Section 8.03). If no
Administrative Agent Termination Event has occurred and is continuing with
respect to any given Series, the
 
                                       34
<PAGE>
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 (Section
8.01).
 
THE TRUSTEE
 
     The Trustee for any given Series of Certificates under the Trust Agreement
will be named in the related Prospectus Supplement. The commercial bank,
national banking association or trust company serving as Trustee will be
unaffiliated with, but may have normal banking relationships with, the
Depositor, any Administrative Agent and their respective affiliates.
 
                 LIMITATIONS ON ISSUANCE OF BEARER CERTIFICATES
 
     In compliance with United States Federal income tax laws and regulations,
the Depositor and any underwriter, agent or dealer participating in the offering
of any Bearer Certificate will agree that, in connection with the original
issuance of such Bearer Certificate and during the period ending 40 days after
the issue of such Bearer Certificate, they will not offer, sell or deliver such
Bearer Certificate, directly or indirectly, to a U.S. Person or to any person
within the United States; except to the extent permitted under U.S. Treasury
regulations.
 
     Bearer Certificates will bear a legend to the following effect: 'Any United
States Person who holds this obligation will be subject to limitations under the
United States income tax laws, including the limitations provided in Sections
165(j) and 1287(a) of the Internal Revenue Code.' The sections referred to in
the legend provide that, with certain exceptions, a United States taxpayer who
holds Bearer Certificates will not be allowed to deduct any loss with respect
to, and will not be eligible for capital gain treatment with respect to any gain
realized on a sale, exchange, redemption or other disposition of, such Bearer
Certificates.
 
     As used herein, 'United States' means the United States of America and its

possessions, and 'U.S. Person' means a citizen or resident of the United States,
a corporation, partnership or other entity created or organized in or under the
laws of the United States, or an estate or trust the income of which is subject
to United States Federal income taxation regardless of its source.
 
     Pending the availability of a definitive Global Security or individual
Bearer Certificates, as the case may be, Certificates that are issuable as
Bearer Certificates may initially be represented by a single temporary Global
Security, without interest coupons, to be deposited with a common depositary in
London for Morgan Guaranty Trust Company of New York, Brussels Office, as
operator of the Euroclear System ('Euroclear'), and Cedel Bank, societe anonyme
('CEDEL') for credit to the accounts designated by or on behalf of the
purchasers thereof. Following the availability of a definitive Global Security
in bearer form, without coupons attached, or individual Bearer Certificates and
subject to any further limitations described in the applicable Prospectus
Supplement, the temporary Global Security will be exchangeable for interests in
such definitive Global Security or for such individual Bearer Certificates,
respectively, only upon receipt of a 'Certificate of Non-U.S. Beneficial
Ownership.' A 'Certificate of Non-U.S. Beneficial Ownership' is a certificate to
the effect that a beneficial interest in a temporary Global Security is owned by
a person that is not a U.S. Person or is owned by or through a financial
institution in compliance with applicable U.S. Treasury regulations. No Bearer
Certificate will be delivered in or to the United States. If so specified in the
applicable Prospectus Supplement, interest on a temporary Global Security will
be distributed to each of Euroclear and CEDEL with respect to that portion of
such temporary Global Security held for its account, but only upon receipt as of
the relevant Distribution Date of a Certificate of Non-U.S. Beneficial
Ownership.

                                 CURRENCY RISKS
 
EXCHANGE RATES AND EXCHANGE CONTROLS
 
     An investment in a Certificate 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
Certificate. Depreciation of the Specified Currency for a Certificate against
the U.S. dollar would result in a decrease in the effective yield of such
Certificate below its Pass-Through Rate and, in certain circumstances, could
result in a loss to the investor on a U.S. dollar basis.
 
     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 Certificates
denominated in such currency. At present, the Depositor has identified the
following currencies in which distributions of principal, premium and interest
on Certificates may be made: Australian dollars, Canadian dollars, Danish
kroner, Italian lire, Japanese yen, New Zealand dollars, U.S. dollars and ECU.
However, Certificates 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 Certificate, the currency in which amounts then due to be distributed
in respect of such Certificate are distributable would not be available. In that
event, such payments will be made in the manner set forth above under
'Description of Certificates--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 CERTIFICATES DENOMINATED
IN A CURRENCY OTHER THAN U.S. DOLLARS. SUCH CERTIFICATES 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 Certificates who are United States residents. The applicable
Prospectus Supplement for certain issuances of Certificates 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 Certificates.
 
     Any Prospectus Supplement relating to Certificates 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.
 
PAYMENT CURRENCY
 
     Except as set forth below or unless otherwise provided in the applicable
Prospectus Supplement, if distributions in respect of a Certificate are required
to be made in a Specified Currency other than U.S. dollars and such currency is
unavailable due to the imposition of exchange controls or other circumstances
beyond the Depositor's control or is no longer used by the government of the
country issuing such currency or for the settlement of transactions by public
institutions of or within the international banking community, then all
distributions in respect of such Certificate shall be made in U.S. dollars until
such currency is again available or so used. The amounts so payable on any date
in such currency shall be converted into U.S. dollars on the basis of
 
                                       36
<PAGE>
the most recently available Market Exchange Rate for such currency or as
otherwise indicated in the applicable Prospectus Supplement.

 
     If distribution in respect of a Certificate is required to be made in ECU
and ECU is no longer used in the European Monetary System, then all
distributions in respect of such Certificate shall be made in U.S. dollars until
ECU is again so used. The amount of each distribution in U.S. dollars shall be
computed on the basis of the equivalent of the ECU in U.S. dollars, determined
as described below, as of the second Business Day prior to the date on which
such distribution is to be made.
 
     The equivalent of the ECU in U.S. dollars as of any date (the 'Day of
Valuation') shall be determined for the Certificates of any Series and Class by
the applicable Trustee on the following basis. The component currencies of the
ECU for this purpose (the 'Components') shall be the currency amounts that were
components of the ECU as of the last date on which the ECU was used in the
European Monetary System. The equivalent of the ECU in U.S. dollars shall be
calculated by aggregating the U.S. dollar equivalents of the Components. The
U.S. dollar equivalent of each of the Components shall be determined by such
Trustee on the basis of the most recently available Market Exchange Rates for
such Components or as otherwise indicated in the applicable Prospectus
Supplement.
 
     If the official unit of any component currency is altered by way of
combination or subdivision, the number of units of that currency as a Component
shall be divided or multiplied in the same proportion. If two or more component
currencies are consolidated into a single currency, the amounts of those
currencies as Components shall be replaced by an amount in such single currency
equal to the sum of the amounts of the consolidated component currencies
expressed in such single currency. If any component currency is divided into two
or more currencies, the amount of that currency as a Component shall be replaced
by amounts of such two or more currencies, each of which shall be equal to the
amount of the former component currency divided by the number of currencies into
which that currency was divided.
 
     All determinations referred to above made by the applicable Trustee shall
be at its sole discretion and shall, in the absence of manifest error, be
conclusive for all purposes and binding on the related Certificateholders of
such Series.
 
FOREIGN CURRENCY JUDGMENTS
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
Certificates will be governed by and construed in accordance with the law of the
State of New York. Courts in the United States customarily have not rendered
judgments for money damages denominated in any currency other than the U.S.
dollar. A 1987 amendment to the Judiciary Law of the State of New York provides,
however, that an action based upon an obligation denominated in a currency other
than U.S. dollars will be rendered in the foreign currency of the underlying
obligation and converted into U.S. dollars at the rate of exchange prevailing on
the date of the entry of the judgment or decree.
 
                              PLAN OF DISTRIBUTION
 
     Certificates 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 terms of the offering of
any Series of Certificates, which may include the names of any underwriters, or
initial purchasers, the purchase price of such Certificates 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 Certificates may be listed, any restrictions on the sale
and delivery of Certificates in bearer form and the place and time of delivery
of the Certificates to be offered thereby.
 
     If underwriters are used in the sale, Certificates will be acquired by the
underwriters 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 Certificates 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 Lehman Brothers
Inc.,
 
                                       37
<PAGE>
an affiliate of the Depositor. Unless otherwise set forth in the applicable
Prospectus Supplement, the obligations of the underwriters to purchase such
Certificates will be subject to certain conditions precedent, and the
underwriters will be obligated to purchase all such Certificates if any of such
Certificates 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.
 
     Certificates may also be sold through agents designated by the Depositor
from time to time. Any agent involved in the offer or sale of Certificates 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 Certificates 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
Certificates may be deemed to be underwriters and any discounts or commissions
received by them on the sale or resale of Certificates 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 against certain civil liabilities, including
liabilities under the Securities Act, or to contribution with respect to
payments that the agents or underwriters may be required to make in respect
thereof. Agents and underwriters may be customers of, engage in transactions

with, or perform services for, the Depositor or its affiliates in the ordinary
course of business.
 
     Lehman Brothers Inc. is an affiliate of the Depositor. Lehman Brothers
Inc.'s participation in the offer and sale of Certificates complies with the
requirements of Schedule E of the By-Laws of the National Association of
Securities Dealers, Inc. regarding underwriting securities of an affiliate.
 
     As to each Series of Certificates, only those Classes rated in one of the
investment grade rating categories by a Rating Agency will be offered hereby.
Any unrated Classes or Classes rated below investment grade may be retained by
the Depositor or sold at any time to one or more purchasers.
 
     Affiliates of the Underwriters may act as agents or underwriters in
connection with the sale of the Certificates. Any affiliate of the Underwriters
so acting will be named, and its affiliation with the Underwriters described, in
the related Prospectus Supplement. Also, affiliates of the Underwriters may act
as principals or agents in connection with market-making transactions relating
to the Certificates. A Prospectus Supplement will be prepared with respect to
the Certificates for use by such affiliates in connection with offers and sales
related to market-making transactions in the Certificates.
 
                                 LEGAL OPINIONS
 
     Certain legal matters with respect to the Certificates will be passed upon
for the Depositor and the underwriters by Weil, Gotshal & Manges, New York, New
York or other counsel identified in the applicable Prospectus Supplement.
