YOU SHOULD FULLY REVIEW THE RISK FACTORS BEGINNING ON PAGE S-15 OF THIS
PROSPECTUS SUPPLEMENT AND PAGE 2 OF THE ATTACHED PROSPECTUS BEFORE INVESTING IN
THE CLASS A-1 CERTIFICATES.

No governmental agency or instrumentality has insured or guaranteed the class
A-1 certificates or the AOL Time Warner debentures.

The class A-1 certificates will represent interests in the trust only and will
not represent interests in or obligations of any other party.

The class A-1 certificates currently have no trading market.

THE TRUST

- -  will issue two classes of callable certificates, the class A-1 callable
   certificates and the class B-1 callable certificates. Only the class A-1
   callable certificates are offered by this prospectus supplement.
- -  will own $50,000,000 principal amount of 7.700% Debentures due 2032 issued by
   AOL Time Warner Inc. and unconditionally guaranteed by America Online, Inc.,
   Time Warner Inc. and two other affiliates.

EACH CLASS A-1 CERTIFICATE

- -  will evidence the right to receive semi-annual interest payments on its
   certificate principal balance at a pass-through rate of 7.625% per annum, and
   the right to receive a payment of principal and premium, if any, on the final
   distribution date, to the extent such amounts are received by the trust on
   the AOL Time Warner debentures.

- -  will be subject to a call option that upon exercise requires the holder of
   the certificate to sell the certificate to the option holder at a price at
   least equal to the outstanding certificate principal balance of the
   certificate plus any accrued but unpaid interest (a) at any time on or after
   June 21, 2007, or (b) at any time, whether before or after June 21, 2007,

supplement and before we terminate our offering of the class A-1 certificates.
These documents may include Annual Reports on Form 10-K and Current Reports on

UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

United States federal
income tax consequences....  In the opinion of Sidley Austin Brown & Wood LLP,
                             special federal tax counsel to the depositor and
                             the trust, for United States federal income tax
                             purposes, the trust will not be classified as an
                             association or publicly traded partnership taxable
                             as a corporation. The trustee and the holders will,
                             although the matter is not free from doubt, treat
                             the trust as a grantor trust for federal income tax
                             purposes, and consequently, the holder of a
                             certificate will be treated as the owner of a pro
                             rata undivided interest in the trust assets subject
                             to the call option. The terms of the certificates
                             require that each initial certificate holder elect
                             to treat its pro rata undivided interest in the AOL
                             Time Warner debentures and its obligation under the
                             call option represented by its certificates as
                             evidencing the ownership of a single "synthetic"
                             debt instrument for U.S. federal income tax
                             purposes. To do so, each initial certificate holder
                             must make an integration election with respect to
                             the holder's pro rata share of the AOL Time Warner
                             debentures and the call options. To make that
                             election, the initial certificate holder need only
                             retain the integration election form that will be
                             enclosed with the initial certificate holder's
                             trade confirmation. See "United States Federal
                             Income Tax Consequences" below.

Summary of Prospectus Supplement

The following summary highlights selected information from this prospectus
supplement and the attached prospectus and is qualified in its entirety by
reference to the detailed information appearing elsewhere in this prospectus
supplement and the attached prospectus. You should carefully read this entire
prospectus supplement and the attached prospectus to understand the terms of the
class A-1 certificates, the risk factors and the principal tax and other
considerations that are important to you to determine whether an investment in
the class A-1 certificates is appropriate for you.

Depositor..................  Corporate Asset Backed Corporation, a Delaware
                             corporation that is an indirect, wholly-owned
                             limited purpose subsidiary of UBS AG and an
                             affiliate of one of the underwriters. The principal
                             executive office of the depositor is located at 445
                             Broad Hollow Road, Suite 239, Melville, New York
                             11747 (Telephone: (631) 587-4700).

Certificates...............  The trust will issue certificates in two classes,
                             designated as class A-1 callable certificates and
                             class B-1 callable certificates. The trust will
                             issue the certificates pursuant to a trust
                             agreement on June 21, 2002 (the "closing date").
                             The class A-1 certificates and class B-1
                             certificates together will represent, in the
                             aggregate, the entire undivided beneficial
                             ownership interest in the assets of the trust. The
                             certificates do not constitute an obligation of the
                             depositor or any other party. Only the class A-1
                             certificates are offered by this prospectus
                             supplement.

Class A-1 certificates.....  Each class A-1 certificate will have an initial
                             certificate principal balance of $25.00. The
                             certificate principal balance of a class A-1
                             certificate is the amount that you are entitled to
                             receive as a distribution allocable to principal on
                             the final distribution date or upon any earlier
                             redemption of the AOL Time Warner debentures.

                             The class A-1 certificates are expected to trade
                             flat. This means that any accrued and unpaid
                             interest on the class A-1 certificates will be
                             reflected in the trading price, and purchasers will
                             not pay and sellers will not receive any accrued
                             and unpaid interest on the class A-1 certificates
                             not included in the trading price.

                             $50,000,000 in aggregate principal amount of the

                             "AOL Time Warner debentures" means these
                             debentures, exclusive of interest accrued from and
                             including April 8, 2002, to but excluding the
                             closing date, which has been retained by the
                             depositor. Interest accrues on the AOL Time Warner

                             will be payable on May 1, 2032, unless AOL Time
                             Warner redeems the AOL Time Warner debentures
                             earlier as described below. On the closing date,

                             remaining term to maturity of approximately 30
                             years.

                             will not receive any interest or other compensation
                             for the delay in payment. See "Description of the
                             Certificates--Interest Distributions" below.

Final distribution.........  On the final distribution date, you will receive,
                             for each class A-1 certificate, the certificate
                             principal balance of that certificate, plus any
                             accrued and unpaid interest. No distributions of
                             principal are scheduled before the final
                             distribution date.

Redemptions, tenders and
other repurchases..........  As noted above, AOL Time Warner has the right to
                             redeem the AOL Time Warner debentures at any time,
                             and may make tenders for or other repurchases or
                             early repayments of the AOL Time Warner debentures.

     Redemptions...........  If AOL Time Warner redeems some or all of the AOL
                             Time Warner debentures, then a corresponding
                             portion of the certificates will be redeemed. Where
                             there is a partial redemption of the AOL Time
                             Warner debentures, class A-1 certificates and class
                             B-1 certificates will be selected for redemption
                             pro rata based on the certificate principal balance
                             of the class A-1 certificates and the certificate
                             notional amount of the class B-1 certificates,
                             except that no fractional repurchases of
                             certificates will be made.

                             Assuming AOL Time Warner makes payments when due,
                             on the third business day after the trustee
                             receives the proceeds of any full or partial
                             redemption of the AOL Time Warner debentures held
                             by the trust, the proceeds will be distributed, as
                             between the class A-1 certificates and the class
                             B-1 certificates selected for redemption, as
                             follows:

                              --  proceeds in respect of principal, and premium,
                                  if any, will be allocated all to the holders
                                  of the class A-1 certificates.

S- 8


                              --  proceeds in respect of interest will be
                                  allocated to the holders of the class A-1
                                  certificates and the class B-1 certificates
                                  pro rata based on interest accrued but not
                                  paid through the redemption date on the
                                  certificate principal balance of the class A-1
                                  certificates and the certificate notional
                                  amount of the class B-1 certificates,
                                  respectively.

                              --  no amounts received in respect of principal or
                                  premium will be distributed to the holders of
                                  the class B-1 certificates.

                             As the holder of a class A-1 certificate that is
                             redeemed, you will receive the following
                             distributions in respect of such proceeds:

                              --  a distribution of the amounts received in
                                  respect of interest at the pass-through rate
                                  of 7.625% per annum through the redemption
                                  date;

                              --  a distribution of the amounts received in
                                  respect of principal in the amount of the
                                  certificate principal balance of the class A-1
                                  certificate on such day; and

                              --  a distribution of your pro rata portion of the
                                  amounts, if any, distributed to the holders of
                                  the class A-1 certificates in respect of
                                  premium on the AOL Time Warner debentures on
                                  such day.

                             If the AOL Time Warner debentures are redeemed, the
                             call option holders are likely to call the
                             certificates to be redeemed and, as a result, to
                             receive most or all the premium described above.

     Tenders and other
       repurchases.........  If AOL Time Warner announces its intention to
                             tender for or otherwise make an unscheduled
                             repayment on or repurchase of the AOL Time Warner
                             debentures, or if a third party announces its
                             intention to tender for the AOL Time Warner
                             debentures, the trustee will be required not to
                             accept any such tender offer or unscheduled
                             repayment or repurchase offer, except in connection
                             with the exercise of call options as set forth
                             below, or if the option is not exercised, upon the
                             unanimous vote of the class A-1 certificate
                             holders.

     Effect of call
options....................  As described above, you will be entitled to receive
                             your pro rata share of the full premium paid by AOL
                             Time Warner as part of the redemption price for the
                             AOL Time Warner debentures, none of which will be
                             payable to the holders of the class B-1
                             certificates. However, if AOL Time Warner announces
                             its intention to redeem, tender for or otherwise
                             make an unscheduled repayment on or repurchase of
                             the AOL Time Warner debentures, or if a third party
                             announces its intention to tender for the AOL Time
                             Warner debentures, the holders of the call options
                             will have the right to purchase your class A-1
                             certificates at a call price equal to their
                             certificate principal balance plus any accrued but
                             unpaid interest (and, if this event occurs before
                             June 21, 2007, the "early call premium amount"
                             described under "Summary of Prospectus
                             Supplement--The Call Options"). This early call
                             premium amount may be less than the premium payable
                             by AOL Time Warner upon

                                                                            S- 9


                             a redemption of, tender for or other repurchase of
                             the AOL Time Warner debentures.

The trust..................  The trust will be established by Corporate Asset
                             Backed Corporation and designated as the CABCO
                             Series 2002-1 Trust (AOL Time Warner Inc.). The
                             trust will be a common law trust formed under the
                             laws of New York, and The Bank of New York will be
                             the trustee of the trust. The assets of the trust
                             will consist of the AOL Time Warner debentures.

The call options...........  As a condition to its initial purchase of class A-1
                             certificates, UBS Warburg LLC will grant to the
                             depositor call options to purchase each of the
                             class A-1 certificates, and as a purchaser of the
                             class A-1 certificates, your ownership of the class
                             A-1 certificates will be subject to those call
                             options. After the call options are granted, the
                             depositor will sell those call options to one or
                             more third parties through UBS Warburg LLC, as
                             agent.

                             A holder of a call option may exercise its option
                             to purchase class A-1 certificates (a) at any time
                             on or after June 21, 2007, or (b) at any time,
                             whether before or after June 21, 2007, after the
                             occurrence of (i) an AOL Time Warner debentures
                             default, (ii) AOL Time Warner's announcement of, or
                             commencement of the formal solicitation of consents
                             to, any amendment to the AOL Time Warner indenture
                             or AOL Time Warner debentures that changes the
                             maturity or the scheduled payment date of any
                             principal, interest or other amount on the AOL Time
                             Warner debentures, or reduces the principal amount
                             of or the interest rate on the AOL Time Warner
                             debentures, or changes the currency in which the
                             principal or interest of the AOL Time Warner
                             debentures is payable, or impairs the right of a
                             holder to institute suit for the enforcement of any
                             such payment on or after the maturity of the AOL
                             Time Warner debentures, or (iii) the delivery by
                             AOL Time Warner (or any third party tender offeror,
                             in the case of a tender offer) of a notice of
                             redemption of, tender offer for, or other
                             unscheduled repayment on or repurchase of, some or
                             all of the AOL Time Warner debentures held by the
                             trust.

                             The Bank of New York will act as your agent (the
                             "option agent") with respect to the call options.

                             The price that an option holder must pay you to
                             purchase your class A-1 certificates will be at
                             least equal to the outstanding certificate
                             principal balance of the certificates purchased
                             plus any accrued and unpaid interest.

                             In addition, an option holder must also pay you the
                             "early call premium amount" if an option holder
                             exercises an option at any time before June 21,
                             2007 as a result of the delivery of a notice of
                             redemption of, tender offer for or other
                             unscheduled repayment on or repurchase of some or
                             all of the AOL Time Warner debentures, as described
                             under "Description of the Certificates--The Class
                             A-1 Certificates--The Call Options" below. The
                             "early call premium amount" will be equal to the
                             sum of the present values of the scheduled interest
                             payments on the AOL Time Warner debentures

S- 10


                             (minus any portion of any scheduled interest
                             payment included in the payment of accrued
                             interest) due after the date the certificates are
                             called and prior to June 21, 2007, discounted to
                             the date the option is exercised at a benchmark
                             U.S. Treasury security rate, plus 35 basis points.
                             The benchmark rate will be determined by the option
                             agent using the same methodology that the trustee
                             for the AOL Time Warner debentures is required to
                             use upon a redemption of the AOL Time Warner
                             debentures, as set forth in the AOL Time Warner
                             prospectus supplement, to calculate the redemption
                             premium on the AOL Time Warner debentures.

                             A holder of a call option may exercise the call
                             option only if:

                              --  it exercises call options with respect to
                                  equal numbers of class A-1 certificates and
                                  class B-1 certificates;

                              --  it acquires class A-1 certificates having an
                                  aggregate certificate principal balance that
                                  is an integral multiple of $1,000;

                              --  it gives the trustee and the option agent at
                                  least 30 days' notice of its exercise, except
                                  that it will be required to give only seven
                                  business days' notice of any exercise as a
                                  result of an AOL Time Warner debentures
                                  default or an announced amendment, redemption,
                                  tender offer, unscheduled repayment or
                                  repurchase, or the commencement of a formal
                                  solicitation of consents to an amendment;

                              --  as a result of the exercise, (A) it purchases
                                  class A-1 certificates and class B-1
                                  certificates having in each case an aggregate
                                  certificate principal balance or an aggregate
                                  certificate notional amount, respectively, of
                                  at least $5,000,000 or, if less, the remaining
                                  aggregate certificate principal balance of the
                                  class A-1 certificates and the remaining
                                  aggregate certificate notional amount of the
                                  class B-1 certificates, and (B) (I) unless the
                                  option holder has exercised all call options
                                  held by it, the aggregate certificate
                                  principal balance of the class A-1
                                  certificates and the aggregate certificate
                                  notional amount of the class B-1 certificates
                                  subject to call options held by the option
                                  holder that have not been exercised is not
                                  less than $5,000,000, respectively, and (II)
                                  the remaining aggregate certificate principal
                                  balance of the class A-1 certificates and the
                                  remaining aggregate certificate notional
                                  amount of the class B-1 certificates, if
                                  greater than zero, is not less than
                                  $5,000,000, respectively.

                             If a holder of call options exercises its call
                             options, the option agent will remit the amount of
                             the call price received to the trustee for payment
                             to the certificate holders whose certificates are
                             called. If a holder of call options exercises
                             options, the trustee will transfer the certificates
                             from you to the option holder without your taking
                             any action. The trustee will then automatically
                             exchange the certificates acquired by the option
                             holder under the options for AOL Time Warner
                             debentures with an aggregate principal amount equal
                             to the aggregate certificate principal balance of
                             those certificates. The called certificates will
                             then be cancelled by the trustee without the need
                             for any further action by you. If you are holding
                             your

                                                                           S- 11


                             certificates in definitive physical form, your
                             called certificates will be cancelled without your
                             taking any action, but you will not receive the
                             purchase price for your certificates until you
                             deliver your called certificates to the trustee.

                             Each holder of a call option has the right to
                             assign its rights under the call option to any
                             person other than the depositor.

                             If call options are exercised with respect to less
                             than all the class A-1 certificates, the class A-1
                             certificates to be purchased will represent a pro
                             rata portion of the class A-1 certificates held by
                             each certificate holder, except that purchases of a
                             fraction of a single class A-1 certificate will not
                             be made, and the trustee may round up or down to
                             avoid fractional purchases.

                             UBS Warburg LLC, as initial purchaser of the class
                             B-1 certificates, will grant similar call options
                             to the depositor. The call price of the call
                             options on the class B-1 certificates will be equal
                             to the present values of the remaining scheduled
                             interest payments on the class B-1 certificates
                             discounted at a yield equal to the initial pricing
                             yield of the class B-1 certificates. Ownership of
                             the class B-1 certificates will be subject to those
                             call options. After the call options are granted,
                             the depositor will sell the call options to one or
                             more third parties through UBS Warburg LLC, as
                             agent.

Class B-1 certificates.....  The class B-1 certificates are not offered by this
                             prospectus supplement. The class B-1 certificates
                             will be issued in minimum notional denominations of
                             $25.00 and multiples of $25.00. The initial
                             aggregate certificate notional amount of all the
                             class B-1 certificates will be $50,000,000.

                             Each class B-1 certificate will represent the right
                             to receive a distribution allocable to interest
                             only, on each distribution date or on any earlier
                             redemption date for the AOL Time Warner debentures,
                             at the pass-through rate of 0.075% per annum on the
                             outstanding certificate notional amount.

                             The holders of the class B-1 certificates will not
                             be entitled to receive any distributions allocable
                             to principal or premium. The final distribution
                             date on the class B-1 certificates is May 1, 2032.

                             The class B-1 certificates will be issued to the
                             depositor. The depositor will sell the class B-1
                             certificates to UBS Warburg LLC, which intends to
                             sell them privately to one or more investors. The
                             class B-1 certificates will be subject to call
                             options substantially similar to the call options
                             on the class A-1 certificates.

Termination of the trust...  By its terms, the trust will terminate 30 days
                             after the final distribution of all amounts due in
                             respect of the AOL Time Warner debentures, or of
                             the AOL Time Warner debentures themselves, to
                             certificate holders.

Ratings....................  The trustee will not issue the class A-1
                             certificates unless the class A-1 certificates have
                             the ratings specified above under "Summary of
                             Principal Economic Terms--The Certificates--
                             Ratings." The ratings address the likelihood that
                             holders of the class A-1 certificates will receive
                             payments of principal equal to the

                             certificate principal balance and payments of
                             interest at the pass-through rate applicable to the
                             class A-1 certificates, and are based primarily on
                             the credit quality of the AOL Time Warner
                             debentures. The ratings are 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, and each rating should be evaluated
                             independently of any other rating. The ratings do
                             not address the occurrence or frequency of
                             redemptions or prepayments on, or extensions of the
                             maturity of, the AOL Time Warner debentures, or the
                             probability that the call options will be
                             exercised, or the corresponding effect of those
                             events on the yield to investors. See "Ratings"
                             below.

Listing or quotation of
  certificates.............  The depositor has applied to list the class A-1
                             certificates on the New York Stock Exchange. If the
                             application is approved, trading of the class A-1
                             certificates on the New York Stock Exchange is
                             expected to commence within a 30-day period after
                             the initial delivery of the certificates. See
                             "Supplemental Plan of Distribution" in this
                             prospectus supplement.

                             You should be aware that the listing or quotation
                             of the class A-1 certificates on the New York Stock
                             Exchange will not ensure that a liquid trading
                             market will be available for the class A-1
                             certificates.

Underwriters...............  UBS Warburg LLC and RBC Dain Rauscher Inc. are the
                             sole underwriters for the offering and sale of the
                             class A-1 certificates. After the initial offering,
                             UBS Warburg LLC and/or its affiliates intend to buy
                             and sell class A-1 certificates to create a
                             secondary market for the holders of the class A-1
                             certificates and may engage in other activities
                             described in the section "Supplemental Plan of
                             Distribution" in this prospectus supplement.
                             However, neither UBS Warburg LLC nor any of its
                             affiliates will be obligated to make a secondary
                             market in the class A-1 certificates, or to
                             continue secondary market activities once started.
                             See "Risk Factors" below.

United States federal
income tax consequences....  In the opinion of Sidley Austin Brown & Wood LLP,
                             special federal tax counsel to the trust and the
                             depositor, for United States federal income tax
                             purposes, the trust will not be classified as an
                             association or publicly traded partnership taxable
                             as a corporation. The trustee and the holders will,
                             although the matter is not free from doubt, treat
                             the trust as a grantor trust for federal income tax
                             purposes, and consequently, the holder of a
                             certificate will be treated as the owner of a pro
                             rata undivided interest in the trust assets subject
                             to the call option. The terms of the certificates
                             require that each initial certificate holder elect
                             to treat its pro rata undivided interest in the AOL
                             Time Warner debentures and its obligation under the
                             call option represented by its certificates as
                             evidencing the ownership of a single "synthetic"
                             debt instrument for U.S. federal income tax
                             purposes. To do so, each initial certificate holder
                             must make an integration election with respect to
                             the holder's pro rata share of the AOL Time Warner
                             debentures and the call options. To make that
                             election, the initial certificate holder need

                                                                           S- 13


                             only retain the integration election form that will
                             be enclosed with the initial certificate holder's
                             trade confirmation. See "United States Federal
                             Income Tax Consequences" below.

ERISA considerations.......  Employee benefit plans subject to the Employee
                             Retirement Income Security Act of 1974, as amended
                             ("ERISA") and individual retirement accounts, Keogh
                             plans and other similar plans (each, a "plan") can
                             generally purchase the class A-1 certificates.
                             However, each plan should consider whether the
                             purchase of the class A-1 certificates is prudent
                             and consistent with the documents governing the
                             plan. The fiduciary rules governing plans are
                             complex and individual considerations may apply to
                             a particular account. Accordingly, any fiduciary of
                             any plan should consult with its legal advisers to
                             determine whether the purchase of the class A-1
                             certificates is permissible under the fiduciary
                             rules. In addition, by acquiring and holding a
                             class A-1 certificate, a plan will be deemed to
                             have represented and warranted that the acquisition
                             and holding of such certificate does not involve a
                             non-exempt prohibited transaction with respect to
                             the plan under Section 406 of ERISA or section 4975
                             of the Internal Revenue Code. See "ERISA
                             Considerations" below.

Risk factors...............  There are a number of risks associated with any
                             investment in the class A-1 certificates. See the
                             sections called "Risk Factors" in this prospectus
                             supplement and in the attached prospectus.

Risk Factors

You should consider, among other things, the material risk factors described
below and the additional risk factors described in the attached prospectus in
deciding whether to purchase certificates.

YOUR CERTIFICATES WILL REPRESENT AN INTEREST IN THE ASSETS OF THE TRUST ONLY AND
WILL NOT REPRESENT AN OBLIGATION OF OR INTEREST IN THE DEPOSITOR OR ANY OF ITS
AFFILIATES. THE PERFORMANCE OF THE AOL TIME WARNER DEBENTURES WILL AFFECT THE
VALUE OF YOUR INVESTMENT AND YOU WILL EXPERIENCE A LOSS IF LOSSES ARE
EXPERIENCED ON THE TRUST ASSETS.

Your certificates will represent an interest in the assets of the trust only and
will not represent an obligation of or interest in the depositor or any of its
affiliates. The trust has no significant assets other than the AOL Time Warner
debentures. No other assets are available to make payments or distributions with
respect to your certificates. None of the depositor, the trustee, the
underwriters or any of their affiliates is obligated to make any payments in
respect of your certificates if the payments on the AOL Time Warner debentures
are insufficient or not made when due. Consequently, if losses are experienced
on the AOL Time Warner debentures, you will experience a loss on your
investment. Accordingly, you are strongly encouraged to obtain as much
information about the AOL Time Warner debentures as you would if you were
investing directly in the AOL Time Warner debentures. This prospectus supplement
provides only the basic terms of the AOL Time Warner debentures and refers you
to publicly available information about the issuer of the AOL Time Warner
debentures.

NO DUE DILIGENCE INVESTIGATION OF THE AOL TIME WARNER DEBENTURES OR AOL TIME
WARNER HAS BEEN MADE BY THE DEPOSITOR, THE UNDERWRITERS OR THE TRUSTEE.

None of the depositor, the underwriters, the trustee or any of their affiliates
has made, or will make, any investigation of the business condition, financial
or otherwise, of AOL Time Warner, or will verify any reports or information
filed by AOL Time Warner with the SEC or otherwise made available to the public.
You should not construe the issuance of the certificates as an endorsement of
the financial condition or business prospects of AOL Time Warner by the
depositor, the trustee, the underwriters or any of their affiliates. It is
strongly recommended that you consider publicly available financial and other
information about AOL Time Warner as if you were investing directly in AOL Time
Warner and its securities. However, the depositor, the trustee, the underwriters
and their affiliates (a) have not verified, and have not undertaken to verify,
the accuracy, completeness or continued availability of any information by AOL
Time Warner (whether or not filed with the SEC), (b) have made no investigation
of the financial condition or creditworthiness of AOL Time Warner, and (c)
assume no responsibility for any information considered by any purchaser or
potential purchaser of the certificates that is not contained in this prospectus
supplement or the attached prospectus.

THE ABILITY OF AOL TIME WARNER TO MAKE PAYMENTS MAY BE AFFECTED BY THE SUCCESS
OF ITS BUSINESS PLANS, ECONOMIC DEVELOPMENTS AND OTHER FACTORS.

Financial difficulties experienced by AOL Time Warner could cause delays in
payment, partial payment or nonpayment on the AOL Time Warner debentures and
your certificates. Furthermore, the business of AOL Time Warner is vulnerable to
adverse business conditions, such as economic factors and increased market
competition, all of which may affect payment on the AOL Time Warner debentures,
and in turn, on your certificates. AOL Time Warner is subject to laws permitting
bankruptcy, moratorium, reorganization and other actions. If AOL Time Warner
does not make payment on the AOL Time Warner debentures, you will bear the
burden of the nonpayment.

                                                                           S- 15

RISK FACTORS
- --------------------------------------------------------------------------------

THE AOL TIME WARNER DEBENTURES ARE UNSECURED AND UNSUBORDINATED OBLIGATIONS OF
AOL TIME WARNER.

The AOL Time Warner debentures are unsecured and unsubordinated obligations of
AOL Time Warner and, in a liquidation or bankruptcy proceeding of AOL Time
Warner, the trust will receive payments only after all senior secured creditors
have first been paid. The AOL Time Warner debentures do not have the benefit of
any "sinking fund" or similar arrangement. According to the AOL Time Warner
prospectus, the AOL Time Warner debentures are general unsecured and
unsubordinated obligations that rank on an equal basis with all other unsecured
and unsubordinated indebtedness of AOL Time Warner, but that are subordinated to
the existing and future senior and secured indebtedness of AOL Time Warner.

AOL TIME WARNER MAY REDEEM OR REPURCHASE THE DEBENTURES BEFORE THE FINAL
MATURITY DATE.

AOL Time Warner will have the right to redeem or repay the AOL Time Warner
debentures in whole at any time or in part from time to time, and may also
tender for or otherwise repurchase the AOL Time Warner debentures. If AOL Time
Warner debentures are redeemed or repurchased, the certificates will be
correspondingly redeemed. See "Description of the AOL Time Warner
Debentures--Optional Redemption."

DISTRIBUTIONS AND OTHER PAYMENTS WITH RESPECT TO YOUR CERTIFICATES AND YOUR
EXPECTED INVESTMENT YIELD MAY BE AFFECTED BY FACTORS SUCH AS THE PERFORMANCE OF
THE TRUST ASSETS, THE REDEMPTION OF THE AOL TIME WARNER DEBENTURES AND THE
EXERCISE OF CALL OPTIONS.

A number of factors may affect the timing of distributions with respect to your
certificates and the yield that you realize on your certificates, including:

- - the purchase price you pay for your certificates;

- - the performance of the AOL Time Warner debentures;

- - whether AOL Time Warner redeems, repurchases or repays the AOL Time Warner
  debentures before their maturity;

- - whether AOL Time Warner defaults under the AOL Time Warner debentures; and

- - whether the holders of the call options exercise their call options on your
  certificates.

None of the depositor, the trustee or the underwriters can predict whether or
when the call options will be exercised or the AOL Time Warner debentures will
be redeemed, repaid, repurchased or accelerated. If the certificates are prepaid
or if the holders of the call options exercise their call options prior to the
final distribution date, then the principal of your certificates or the call
price will be paid to the extent funds are received on the debentures or the
holders of the call options pay the call price and your investment in the
certificates will have a shorter average maturity.

IF THE CERTIFICATES ARE PREPAID OR IF THE HOLDERS OF THE CALL OPTIONS EXERCISE
THEIR CALL OPTIONS WHEN PREVAILING MARKET INTEREST RATES ARE LOWER THAN THE
YIELD ON YOUR CERTIFICATES, YOU MAY BE UNABLE TO REALIZE A COMPARABLE YIELD WHEN
YOU REINVEST THE FUNDS THAT YOU RECEIVE FROM THE PREPAYMENT OF YOUR
CERTIFICATES.

If the certificates are prepaid or if the holders of the call options exercise
their call options when prevailing market interest rates are lower than the
yield on your certificates, you may be unable to

S- 16

RISK FACTORS
- --------------------------------------------------------------------------------

realize a comparable yield when you reinvest the funds that you receive from the
prepayment of your certificates.

HOLDERS OF CLASS A-1 CERTIFICATES ARE NOT LIKELY TO RECEIVE REDEMPTION PREMIUMS.

In certain circumstances, redemption of the AOL Time Warner debentures by AOL
Time Warner may require payment of a redemption premium. However, in such
circumstances it is likely that the holders of the call options will exercise
their right to purchase the class A-1 certificates pursuant to the call options.
The call price will be at all times at least equal to the outstanding principal
amount of the class A-1 certificates plus any accrued and unpaid interest, plus,
if the call options are exercised prior to June 21, 2007, the "early call
premium amount", as described under "Description of the Certificates--The Class
A-1 Certificates--The Call Options" below. If the call options are exercised
prior to June 21, 2007, in respect of an optional redemption of the AOL Time
Warner debentures, the "early call premium amount" payable on the call options
will be at most a small portion of any premium paid by AOL Time Warner.

OWNING THE CERTIFICATES IS NOT THE SAME AS OWNING THE AOL TIME WARNER DEBENTURES
DIRECTLY.

Although the trustee will pass through to certificate holders directly any
payments that it receives in relation to the AOL Time Warner debentures and you
can exercise "pass-through" voting in some circumstances, holding certificates
that represent an interest in the AOL Time Warner debentures will differ from
owning the AOL Time Warner debentures directly. For instance, if AOL Time Warner
or a third party redeems the AOL Time Warner debentures or AOL Time Warner
otherwise makes an unscheduled repayment, the call option holders will likely
receive most or all of any premium that you would otherwise have received if you
owned AOL Time Warner debentures directly. With respect to voting of the AOL
Time Warner debentures, there are certain matters that the trustee may not
consent to (except at the direction of a majority or, in some instances all, of
the class A-1 certificate holders) that you would be able to consent to if you
owned the AOL Time Warner debentures directly.

THE TRADING PRICE OF YOUR CERTIFICATES WILL BE DIRECTLY AFFECTED BY THE TRADING
PRICE OF THE AOL TIME WARNER DEBENTURES, AND YOUR ABILITY TO REALIZE MARKET
VALUE APPRECIATION IS CAPPED BY THE CALL PRICE.

Your certificates will represent undivided beneficial interests in the AOL Time
Warner debentures. Accordingly, if the trading price of the AOL Time Warner
debentures increases or decreases, the trading price of your class A-1
certificates is likely to increase or decrease as well, though it is unlikely to
increase above the call price of the call options. The holder of each call
option will determine whether to exercise the option solely on the basis of that
party's self interest, and is expected to exercise its call option when it is
profitable to do so (that is, when the value of the interests in the AOL Time
Warner debentures evidenced by the class A-1 certificates exceeds the call
price). Exercise of the call options will allow the option holders to obtain the
value of the interests in the AOL Time Warner debentures evidenced by the class
A-1 certificates in excess of the call price for themselves, by taking such
excess value away from the certificate holders. See "Yield on the Certificates"
below and "Maturity and Yield Considerations" in the attached prospectus.

A TRADING MARKET FOR YOUR CERTIFICATES MAY NOT DEVELOP OR CONTINUE; THUS IT MAY
BE DIFFICULT TO RESELL YOUR CERTIFICATES.

Prior to the issuance of the class A-1 certificates there will not be a public
market for those securities. The underwriters may assist in resales of the class
A-1 certificates, but are not obligated to do so. A

                                                                           S- 17

RISK FACTORS
- --------------------------------------------------------------------------------

trading market for the class A-1 certificates may not develop. Even if a
secondary market does develop, it may not continue or be sufficiently liquid to
allow you to resell your class A-1 certificates.

YOUR CERTIFICATES REPRESENT INTERESTS IN OBLIGATIONS OF A SINGLE OBLIGOR AND, AS
A RESULT, THE CREDIT RISK IS CONCENTRATED IN A SINGLE OBLIGOR.

Your class A-1 certificates represent interests in obligations of a single
obligor and, as a result, the credit risk is concentrated in a single obligor.
In particular, your class A-1 certificates will be subject to all the risks
associated with a direct investment in unsecured and unsubordinated obligations
of AOL Time Warner.

A REDUCTION OR WITHDRAWAL OF THE SECURITY RATING OF YOUR CERTIFICATES WOULD
ADVERSELY AFFECT THEIR VALUE.

On the closing date, the class A-1 certificates will be rated Baa1 by Moody's
and BBB+ by Standard & Poor's. We cannot assure you that either rating will not
be lowered or withdrawn by the applicable rating agency in the future. If the
rating assigned by any rating agency to the AOL Time Warner debentures is
reduced, the rating assigned to your class A-1 certificates will likely be
reduced as well. Any reduction in the rating of your class A-1 certificates may
adversely affect their value.

NO RULINGS WILL BE OBTAINED FROM THE IRS CONCERNING THE CERTIFICATES AND THE IRS
MAY DISAGREE WITH FEDERAL TAX COUNSEL.

Sidley Austin Brown & Wood LLP, special federal tax counsel to the depositor and
the trust, has provided an opinion regarding the tax classification of the
trust. However, opinions of counsel are not binding on the IRS or the courts. In
addition, you should be aware that no rulings will be sought from the IRS with
respect to any of the federal income tax consequences discussed in this
prospectus supplement, and no assurance can be given that the IRS will not take
contrary positions. Accordingly, you should consult your tax advisor to
determine the federal, state, local and other tax consequences of the purchase,
ownership and disposition of the class A-1 certificates. See "United States
Federal Income Tax Consequences" in this prospectus supplement and the attached
prospectus.

THE LIQUIDITY OF YOUR CERTIFICATES MAY BE REDUCED IF AOL TIME WARNER STOPS
MAKING INFORMATION ABOUT ITS FINANCIAL CONDITION AND BUSINESS PUBLICLY
AVAILABLE.

The information that AOL Time Warner makes available to the public is important
to prospective buyers of your class A-1 certificates. To the extent that AOL
Time Warner ceases to make information about itself and its AOL Time Warner
debentures publicly available, your ability to sell your class A-1 certificates
or to obtain a favorable price upon sale could be adversely affected. If AOL
Time Warner stops making information about its financial condition and business
publicly available, the trust will take actions intended to increase the
likelihood that AOL Time Warner will be required to resume making this
information available as described under "Description of the
Certificates--Termination of Book-Entry Registration in Connection with
Suspension of Securities Exchange Act Reporting by AOL Time Warner" below.
However, there is no certainty that these steps will be effective.

S- 18


- --------------------------------------------------------------------------------

Formation of the Trust

The trust will be a common law trust formed under the laws of the State of New
York pursuant to the trust agreement, to be dated as of June 21, 2002, between
the depositor and the trustee. Concurrently with the execution and delivery of
the trust agreement, the depositor will transfer and sell the AOL Time Warner
debentures to the trust in exchange for the issuance of the certificates. The
trustee, on behalf of the trust, will accept the AOL Time Warner debentures and
will deliver the certificates to the depositor. The depositor will sell the
certificates to UBS Warburg LLC for resale to investors. As a condition to its
initial purchase of class A-1 certificates, UBS Warburg LLC will grant to the
depositor call options to purchase each of the class A-1 certificates at a price
at least equal to the outstanding certificate principal balance of the
certificates purchased plus any accrued and unpaid interest. As a purchaser of
the class A-1 certificates, your ownership of the class A-1 certificates will be
subject to those call options. The call price will include an additional amount
under the limited circumstances described under "Description of the
Certificates--The Class A-1 Certificates--The Call Options" below. After the
call options are granted, the depositor will sell the call options to one or
more third parties through UBS Warburg LLC, as agent.

The AOL Time Warner debentures will be purchased by the depositor from UBS
Warburg LLC. The AOL Time Warner debentures will not be acquired from AOL Time
Warner as part of any distribution by, or pursuant to any agreement with, AOL
Time Warner. AOL Time Warner is not participating in this offering and will not
receive any of the proceeds of the sale of the AOL Time Warner debentures to the
depositor or the issuance of the certificates. Neither the depositor nor any of
its affiliates participated in the initial public offering of the AOL Time
Warner debentures.

                                                                           S- 19

Description of the AOL Time Warner Debentures

The AOL Time Warner debentures will consist solely of publicly tradable 7.700%
Debentures due 2032 issued by AOL Time Warner. The AOL Time Warner debentures
were originally issued by AOL Time Warner as part of an underwritten public
offering of $2,000,000,000 aggregate principal amount of the 7.700% AOL Time
Warner Debentures due 2032 and $4,000,000,000 aggregate principal amount of
three series of notes maturing between 2005 and 2012, pursuant to a registration
statement on Form S-3 filed by AOL Time Warner with the SEC under the Securities
Act.

This prospectus supplement sets forth the material terms of the AOL Time Warner
debentures and the AOL Time Warner indenture, as described in the prospectus
supplement, dated April 3, 2002 (the "AOL Time Warner prospectus supplement"),
and the prospectus, dated February 26, 2001 (the "AOL Time Warner prospectus"),
issued by AOL Time Warner in connection with the issuance of the AOL Time Warner
debentures. This prospectus supplement does not provide detailed information
about the AOL Time Warner debentures. This prospectus supplement relates only to
the class A-1 certificates offered by this prospectus supplement and is not an
offering document for the AOL Time Warner debentures. AOL Time Warner is subject
to the information reporting requirements of the Securities Exchange Act and
files reports and other information with the SEC. All disclosure with respect to
the AOL Time Warner debentures is derived from publicly available documents. See
"--Available Information" below.

Although neither the depositor nor the underwriters are aware of any reason to
doubt the reliability of the information about the AOL Time Warner debentures,
the AOL Time Warner indenture or AOL Time Warner set forth in the AOL Time
Warner prospectus supplement, the AOL Time Warner prospectus, the registration
statement relating to the AOL Time Warner debentures or any other publicly
available information, neither the depositor nor the underwriters have
participated in the preparation of these documents or made any due diligence
inquiry with respect to the information provided in these documents, and no
representation is made by the depositor or the underwriters as to the accuracy
or completeness of the information contained in the AOL Time Warner prospectus
supplement, the AOL Time Warner prospectus, the registration statement relating
to the AOL Time Warner debentures or any other publicly available information
relating to AOL Time Warner or the AOL Time Warner debentures. Neither the
depositor nor the underwriters have verified the accuracy or completeness of
these documents or reports. Events affecting the AOL Time Warner debentures or
AOL Time Warner may have occurred that have not yet been publicly disclosed.
This would affect the accuracy or completeness of the publicly available
documents described above.

* A rating of the AOL Time Warner debentures is not a recommendation to
  purchase, hold or sell those securities, inasmuch as the rating does not
  comment as to the market price of the securities or the suitability of the
  securities for a particular investor (such as the trust or the holder of a
  certificate). A rating may be reduced or withdrawn by the assigning rating
  organization at any time, and each rating should be evaluated independently of
  any other rating. Any reduction or withdrawal of the security rating with
  respect to the AOL Time Warner debentures would adversely affect the value of
  those securities and may cause a reduction or withdrawal of the rating of your
  certificates. See "Ratings" below.

The AOL Time Warner debentures represent the sole source of funds that are
available to make distributions in respect of your certificates. Consequently,
your ability to receive distributions in respect of your certificates will
depend on the trust's receipt of payments on, or in respect of, the AOL Time
Warner debentures.

This description of the AOL Time Warner debentures is qualified in its entirety
by, and should be read in conjunction with (a) the AOL Time Warner prospectus
supplement, (b) the AOL Time Warner prospectus and (c) the registration
statement relating to the AOL Time Warner debentures of which the AOL Time
Warner prospectus supplement and the AOL Time Warner prospectus are a part.

INTEREST PAYMENTS

Interest accrues on the AOL Time Warner debentures at an annual rate of 7.700%,
from April 8, 2002, until the principal is paid or made available for payment.
Interest at that rate is payable on the AOL Time Warner debentures semi-annually
in arrears on each May 1 and November 1.

Interest on the AOL Time Warner debentures is calculated on the basis of a
360-day year of twelve 30-day months.

                                                                           S- 21

DESCRIPTION OF THE AOL TIME WARNER DEBENTURES
- --------------------------------------------------------------------------------

PRINCIPAL PAYMENTS

Generally, principal payments due to the holders of the AOL Time Warner
debentures are scheduled to be paid on May 1, 2032, but may be paid earlier than
that date if AOL Time Warner redeems the AOL Time Warner debentures before that
date.

OPTIONAL REDEMPTION

AOL Time Warner has the right to redeem the AOL Time Warner debentures in whole
or in part at any time and from time to time, on at least 30 days' but not more
than 60 days' prior notice mailed to the holders of the AOL Time Warner
debentures and published in a leading newspaper having general circulation in
Luxembourg, so long as the debentures are listed on the Luxembourg Stock
Exchange. The redemption price would be equal to the greater of (i) 100% of the
principal amount of the AOL Time Warner debentures to be redeemed and (ii) the
sum of the present values of the remaining scheduled payments (as defined in the
AOL Time Warner indenture) of principal of, and interest on, the AOL Time Warner
debentures that would be due after the redemption date discounted to the
redemption date on a semi-annual basis (assuming a 360-day year consisting of
twelve 30-day months) at the benchmark U.S. Treasury security rate selected as
described in the AOL Time Warner prospectus supplement, plus 35 basis points,
together, in either case, with any accrued interest to the date of redemption
that has not been paid.

On and after any redemption date, interest will cease to accrue on the AOL Time
Warner debentures or any portion thereof that is redeemed. On or before any
redemption date, AOL Time Warner must deposit with a paying agent (or the AOL
Time Warner debentures trustee) money sufficient to pay the redemption price of
the AOL Time Warner debentures to be redeemed on that date. If less than all the
AOL Time Warner debentures are to be redeemed, the AOL Time Warner debentures to
be redeemed must be selected by the AOL Time Warner debentures trustee by such
method as the AOL Time Warner debentures trustee deems fair and appropriate.

DEFEASANCE

AOL Time Warner (and to the extent applicable, each of the guarantors) (i) will
be discharged from its indebtedness represented by the AOL Time Warner
debentures and all of its obligations under the AOL Time Warner indenture and
the AOL Time Warner debentures, except for certain obligations to register the
transfer or exchange of AOL Time Warner debentures, replace stolen, lost or
mutilated AOL Time Warner debentures, maintain paying agencies and hold moneys
for payment in trust, (ii) be released from its obligations under certain
restrictive covenants under the AOL Time Warner indenture, and (iii) cause
certain events of default (other than those arising out of the failure to pay
interest or principal on the AOL Time Warner debentures and certain events of
bankruptcy, insolvency and reorganization) to no longer constitute events of
default, in each case if AOL Time Warner deposits in trust with the AOL Time
Warner debentures trustee money or U.S. government obligations in an amount
sufficient to pay the principal of, and interest on, the applicable AOL Time
Warner debentures to maturity. If AOL Time Warner wishes to be discharged of its
indebtedness or relieved of its obligations under certain restrictive covenants,
it must, among other things, deliver to the trustee the following documents:

- - an opinion of counsel stating that (a) the deposit and related defeasance
  would not cause the holders of the AOL Time Warner debentures to recognize
  income, gain or loss for federal income tax purposes and, in the case of a
  discharge of the AOL Time Warner debentures and AOL Time Warner indenture,
  accompanied by a ruling to such effect received from or published by the
  United States Internal Revenue Service, and (b) the creation of the defeasance
  trust will not violate the Investment Company Act of 1940; and

S- 22

DESCRIPTION OF THE AOL TIME WARNER DEBENTURES
- --------------------------------------------------------------------------------

- - a certificate by an officer of AOL Time Warner stating that such deposit was
  not made with the intent of preferring the holders of the AOL Time Warner
  debentures over other creditors of AOL Time Warner or with the intent of
  defeating, hindering, delaying or defrauding creditors of AOL Time Warner or
  others.

GUARANTEES

Each of America Online and Time Warner guarantees (a) the full and punctual
payment of principal, interest and all other monetary obligations of AOL Time
Warner on the AOL Time Warner debentures, when due, whether at maturity, by
acceleration, by redemption or otherwise, and (b) the full and punctual
performance within applicable grace periods of all other obligations of AOL Time
Warner under the AOL Time Warner indenture and the AOL Time Warner debentures.
Additionally, Time Warner Companies and Turner Broadcasting System guarantee
Time Warner's guarantee of the AOL Time Warner debentures under substantially
the same terms as the guarantees of America Online and Time Warner of the AOL
Time Warner debentures.

SENIOR UNSECURED OBLIGATIONS

The AOL Time Warner debentures are senior unsecured obligations of AOL Time
Warner and will rank equally and ratably with all other senior unsecured and
unsubordinated indebtedness of AOL Time Warner. The guarantees of the AOL Time
Warner debentures are senior obligations of America Online, Time Warner, Time
Warner Companies, and Turner Broadcasting System, as applicable, and are direct
unsecured obligations of America Online, Time Warner, Time Warner Companies and
Turner Broadcasting System, respectively, ranking equally with all other
unsecured and unsubordinated obligations of America Online, Time Warner, Time
Warner Companies, and Turner Broadcasting System, respectively. Each of the
guarantors is a holding company and the AOL Time Warner debentures and the
guarantees will be effectively subordinated to all existing and future
liabilities, including indebtedness, of the subsidiaries of AOL Time Warner,
America Online, Time Warner, Time Warner Companies, and Turner Broadcasting
System, respectively.

AOL TIME WARNER DEBENTURES DEFAULTS

The following is a summary description of the events of default under the AOL
Time Warner debentures:

- - default for 30 days in payment of interest on any AOL Time Warner debenture;

- - default in payment of principal or payment of premium, if any, on any AOL Time
  Warner debenture when due;

- - failure by AOL Time Warner (or any of the guarantors, if applicable) to comply
  with any covenant in the AOL Time Warner indenture for a period of 90 days
  after written notice is given to it by the AOL Time Warner indenture trustee
  or holders of 25% of the aggregate principal amount of the AOL Time Warner
  debentures, as specified in the AOL Time Warner indenture;

- - certain events of bankruptcy, insolvency or reorganization of AOL Time Warner
  or any U.S. material subsidiary (as defined in the AOL Time Warner indenture);
  and

- - any guarantee ceasing to be, or asserted by any guarantor as not being, in
  full force and effect and enforceable according to its terms, except to the
  extent contemplated by the AOL Time Warner indenture.

                                                                           S- 23

Yield on the Certificates

The yield that you receive on your class A-1 certificates will be affected by a
number of factors, including:

- - the purchase price you pay for your class A-1 certificates;

- - the performance of the AOL Time Warner debentures;

- - whether AOL Time Warner redeems, repurchases or repays the AOL Time Warner
  debentures before their maturity;

- - whether AOL Time Warner defaults on the AOL Time Warner debentures; and

- - whether the holder of any call option exercises its call option on your
  certificates.

A holder of call options (initially the depositor) may exercise its options to
purchase some or all of your class A-1 certificates (a) at any time on or after
June 21, 2007, or (b) at any time, whether before or after June 21, 2007, after
the occurrence of (i) an AOL Time Warner debentures default, (ii) AOL Time
Warner's announcement of, or commencement of formal solicitation of consents to,
any of certain material amendments described in this prospectus supplement to
the AOL Time Warner indenture or the AOL Time Warner debentures, or (iii) the
delivery by AOL Time Warner (or any third party tender offeror, in the case of a
tender offer) of a notice of redemption of, tender offer for, or other
unscheduled repayment on or repurchase of, some or all of the AOL Time Warner
debentures held by the trust.

In certain circumstances, AOL Time Warner is required to pay a redemption
premium. In addition, the market value of the AOL Time Warner debentures may
increase to a value in excess of their face amounts. However, in either of these
circumstances it is likely that the holders of the call options will exercise
their right to purchase the class A-1 certificates pursuant to the call options.

The price that an option holder must pay you to purchase your class A-1
certificates will be at least equal to the outstanding certificate principal
balance of the certificates purchased plus any accrued and unpaid interest and,
if the option is exercised prior to June 21, 2007, as a result of the
redemption, tender offer for or other repurchase or repayment of the AOL Time
Warner debentures, a portion of any premium paid by AOL Time Warner (or any
third party, in the case of a tender offer). See "Description of the
Certificates--The Class A-1 Certificates--The Call Options" below. If a holder
of a call option exercises its call option, you may receive less than the market
value of the AOL Time Warner debentures evidenced by your class A-1
certificates, and you will receive only some (or, in some cases, none) of the
premium paid by AOL Time Warner. The holder of the call option will determine
whether to exercise the option solely on the basis of its own self interest, and
you should expect it to exercise the call option when it is profitable to do so
(that is, when the value of the class A-1 certificates and class B-1
certificates exceeds their call price). Exercising call options will allow the
option holders to obtain the value of the certificates in excess of the call
price for themselves, by taking such excess value away from the certificate
holders. See "Maturity and Yield Considerations" in the attached prospectus.

If the class A-1 certificates are redeemed or a call option is exercised prior
to the scheduled final distribution date on the class A-1 certificates, and at
the time prevailing market interest rates are lower than the yield on your
certificates, you may be unable to realize a comparable yield when you reinvest
the funds that you receive from the prepayment or purchase of your certificates.

Description of the Certificates

The certificates will consist of two classes of certificates, designated as the
class A-1 callable certificates and the class B-1 callable certificates. The
certificates will be denominated, and distributions with respect to the
certificates will be payable, in U.S. dollars, their specified currency. The
class A-1 certificates and the class B-1 certificates together will represent,
in the aggregate, the entire beneficial ownership interest in the assets of the
trust. Only the class A-1 certificates are offered by this prospectus
supplement.

THE CLASS A-1 CERTIFICATES

CERTIFICATE PRINCIPAL BALANCE
Each class A-1 certificate will have an initial certificate principal balance of
$25.00. The aggregate initial certificate principal balance of all the class A-1
certificates will be $50,000,000. The certificate principal balance of a
certificate is the amount that the certificate holder is entitled to receive as
a distribution allocable to principal on the final distribution date or upon any
earlier redemption of the AOL Time Warner debentures.

INTEREST DISTRIBUTIONS
The pass-through rate applicable to the class A-1 certificates will be 7.625%
per annum. You will be entitled to distributions on your certificates allocable
to interest, to the extent that funds are received on the AOL Time Warner
debentures, at the pass-through rate, applied to the certificate principal
balance of your class A-1 certificates.

Distributions allocable to interest will be made on the class A-1 certificates
on each distribution date. The distribution dates on the class A-1 certificates
will be each May 1 and November 1, beginning November 1, 2002 (or if any of
those days is not a business day, the next succeeding business day). The last
scheduled distribution date (the "final distribution date") will be May 1, 2032.

A "business day" is any day other than (a) a Saturday, a Sunday or a day on
which banking institutions in the City of New York are authorized or obligated
by law or executive order to be closed for business, or (b) a day that is not a
business day for purposes of the AOL Time Warner debentures.

On each distribution date, the trust will distribute the funds as described
under "--Distributions" below. The amount allocable to your class A-1
certificates on each distribution date will be equal to the pass-through rate on
your class A-1 certificates, multiplied by the certificate principal balance of
your class A-1 certificates on the distribution date. The distribution made on
the class A-1 certificates on each distribution date will be made to the person
in whose name the certificate is registered on the related record date, which
will be the 15th calendar day prior to the distribution date, whether or not a
business day.

The trust will make distributions on any distribution date only to the extent it
receives funds on the AOL Time Warner debentures before 1:00 p.m. on that date.
If the trust receives a payment on the AOL Time Warner debentures after 1:00
p.m. on any distribution date, the trustee will use commercially reasonable
efforts to make distributions on the same date. If the trust does not receive a
payment on the AOL Time Warner debentures in time to make a payment on any
distribution date, then, subject to the provisions discussed under "Description
of the Trust Agreement--AOL Time Warner Debentures Defaults" below, the trustee
will make the distribution on the first business day following the date on which
it receives payment on the AOL Time Warner debentures. You will not receive any
interest or other compensation in respect of any delay in payment (although your
pro rata share of any interest or other compensation paid on the AOL Time Warner
debentures will be passed through to you as a class A-1 certificate holder).

S- 26

DESCRIPTION OF THE CERTIFICATES
- --------------------------------------------------------------------------------

FORM OF CERTIFICATES; BOOK-ENTRY ISSUANCE
The class A-1 certificates will be issued in fully registered form in
denominations of $25.00 and multiples of $25.00.

The class A-1 certificates will initially be represented by one or more global
certificates registered in the name of Cede & Co., as nominee of The Depository
Trust Company ("DTC"). No beneficial owner of any of these certificates will be
entitled to receive a certificate representing that person's interest, except as
set forth under "--Definitive Certificates" below. Unless and until definitive
certificates are issued under the circumstances described below, all references
to actions by holders with respect to any class A-1 certificates will refer to
actions taken by DTC upon instructions from its participants. See "--Definitive
Certificates" below and "Description of the Certificates--Global Securities;
Holdings in Street Name" in the attached prospectus.

DEFINITIVE CERTIFICATES
Definitive certificates will be issued to you or your nominee, rather than to
DTC or its nominee, only if (a) DTC or the depositor advises the trustee that
DTC is no longer willing or able to continue as depositary with respect to the
class A-1 certificates and the depositor does not appoint a qualified successor
within 90 days, or (b) if AOL Time Warner ceases to file Securities Exchange Act
reports as described below under "--Termination of Book-Entry Registration in
Connection with Suspension of Securities Exchange Act Reporting by AOL Time
Warner."

Upon the occurrence of either event described in the preceding paragraph, the
trustee is required to notify (i) all DTC participants with interests in the
class A-1 certificates of the availability of definitive certificates through
DTC and (ii) in the case of an event described in clause (b) of the preceding
paragraph, DTC, of the occurrence of any such event and of the trustee's intent
to make definitive certificates available. Upon surrender by DTC of the global
certificates registered in the name of the nominee of DTC and receipt of
instructions for re-registration, the trustee will reissue the class A-1
certificates as definitive certificates in the respective certificate principal
balances specified by DTC, and thereafter the trustee will recognize the
registered holders of the definitive class A-1 certificates as holders of
certificates under the trust agreement. See "Description of the
Certificates--Global Securities; Holdings in Street Name" in the attached
prospectus.

TRADING
The depositor has applied to list the class A-1 certificates on the New York
Stock Exchange. If the application is approved, trading of the class A-1
certificates on the New York Stock Exchange is expected to commence within 30
days after the initial delivery of the class A-1 certificates. Listing or
quotation of the class A-1 certificates on the New York Stock Exchange will not
ensure that a liquid trading market will be available for the certificates.

The class A-1 certificates are expected to trade flat. This means that any
accrued and unpaid interest on the class A-1 certificates will be reflected in
the trading price, and purchasers will not pay and sellers will not receive any
accrued and unpaid interest on the class A-1 certificates not included in the
trading price.

THE CALL OPTIONS
As a condition to its initial purchase of class A-1 certificates, UBS Warburg
LLC will grant to the depositor call options to purchase each of the class A-1
certificates, and as a purchaser of the class A-1 certificates, your ownership
of the class A-1 certificates will be subject to those call options. After the
call options are granted, the depositor will sell the call options to one or
more third parties through UBS Warburg LLC, as agent. A holder of call options
may exercise its options to purchase some or all of your class A-1 certificates
(a) at any time on or after June 21, 2007, or (b) at any time, whether before or
after June 21, 2007, after the occurrence of (i) an AOL Time Warner debentures
default,

                                                                           S- 27

DESCRIPTION OF THE CERTIFICATES
- --------------------------------------------------------------------------------

(ii) AOL Time Warner's announcement of, or commencement of formal solicitation
of consents to, any amendment to the AOL Time Warner indenture or AOL Time
Warner debentures that changes the maturity or the scheduled payment date of any
principal, interest or other amount on the AOL Time Warner debentures, or
reduces the principal amount of or the interest rate on the AOL Time Warner
debentures, or changes the currency in which the principal or interest of the
AOL Time Warner debentures is payable, or impairs the right of a holder to
institute suit for the enforcement of any such payment on or after the maturity
of the AOL Time Warner debentures, or (iii) the delivery by AOL Time Warner (or
any third party tender offeror, in the case of a tender offer) of a notice of
redemption of, tender offer for, or other unscheduled repayment on or repurchase
of, some or all of the AOL Time Warner debentures held by the trust. If the
trustee receives any announcement or proposal of an amendment to the AOL Time
Warner indenture or a notice of a redemption of, tender offer for or other
unscheduled repayment on or repurchase of any AOL Time Warner debentures, the
trustee will be required to send a copy of such announcement, proposal or notice
to the option agent for sending to each option holder within two business days.

In the case of any tender offer for the AOL Time Warner debentures (whether by
AOL Time Warner or any third party), if any option holder exercises its call
options with respect to any class A-1 certificates and class B-1 certificates,
then the trustee must tender, in compliance with the tender offer requirements
for the AOL Time Warner debentures, a principal amount of AOL Time Warner
debentures equal to the aggregate certificate principal balance of class A-1
certificates in relation to which a notice of exercise of the related call
options has been given, unless the tender offer price for the AOL Time Warner
debentures is less than the call price that would be required to be paid by the
holder of the call options. If fewer than all the AOL Time Warner debentures
tendered by the trust are accepted for payment and paid for under the tender
offer, then the number of call options deemed exercised will be reduced so that
the certificate principal balance of the class A-1 certificates and the
certificate notional amount of the class B-1 certificates, respectively, subject
to such exercised call options corresponds to the principal amount of AOL Time
Warner debentures tendered by the trust that are accepted for payment and paid
for, and the call options deemed not exercised will remain outstanding. In
addition, if the tender offer is terminated by AOL Time Warner or any other
person making the tender offer before any AOL Time Warner debentures are
accepted for payment and paid for, or if all tenders by the trust of AOL Time
Warner debentures are rejected, then the notice of the exercise of the call
options will be of no further force and effect, and any call options for which
notice of exercise was given will be deemed not exercised and will remain
outstanding. The trustee will pay the difference between the tender offer
proceeds and the call price to the exercising call option holder.

The Bank of New York will execute a call option agreement with the depositor and
UBS Warburg LLC pursuant to which the call options will be granted by UBS
Warburg LLC to the depositor, and will act as your agent (the "option agent")
with respect to the call options.

The price that an option holder must pay you to purchase your class A-1
certificates will be at least equal to the outstanding certificate principal
balance of the class A-1 certificates purchased plus any accrued and unpaid
interest. In addition, an option holder must also pay you an "early call premium
amount" if the option holder exercises an option at any time before June 21,
2007, as a result of the delivery of a notice of redemption of, tender offer for
or other unscheduled repayment on or repurchase of some or all of the AOL Time
Warner debentures. The "early call premium amount" will be equal to the sum of
the present values of the scheduled interest payments on the AOL Time Warner
debentures (minus any portion of any scheduled interest payment included in the
payment of accrued interest) due after the date the certificates are called and
prior to June 21, 2007, discounted to the date the option is exercised at a
benchmark U.S. Treasury security rate, plus 35 basis points. The benchmark rate
will be determined by the option agent using the same methodology that the
trustee for the AOL Time Warner debentures is required to use upon a redemption
of the AOL Time Warner

DESCRIPTION OF THE CERTIFICATES

debentures, as set forth in the AOL Time Warner prospectus supplement, to
calculate the redemption premium on the AOL Time Warner debentures.

UBS Warburg LLC as the initial purchaser of the class B-1 certificates will
grant similar call options to the depositor. The call price of the call options
on the class B-1 certificates will be equal to the present values of the
remaining scheduled interest payments on the class B-1 certificates discounted
at a yield equal to the initial pricing yield of the class B-1 certificates.
After the call options are granted, the depositor will sell the call options to
one or more third parties through UBS Warburg LLC, as agent.

Each purchaser of a class A-1 certificate or class B-1 certificate will be
deemed, by its purchase of such certificate, to have agreed to assume the
obligations of its transferor under the related call options and to appoint the
option agent as its agent to act on its behalf in relation to the related call
options, and the class A-1 and class B-1 certificates will bear a legend to that
effect.

A holder of a call option may exercise the call option only if:

- - it exercises call options with respect to equal numbers of class A-1
  certificates and class B-1 certificates;

- - it acquires class A-1 certificates having an aggregate certificate principal
  balance that is an integral multiple of $1,000;

- - it gives the trustee and the option agent at least 30 days' notice of its
  exercise, except that it will be required to give only seven business days'
  notice of any exercise as a result of an AOL Time Warner debentures default or
  an announced amendment, redemption, tender offer or unscheduled repayment, or
  the commencement of formal solicitation of consents to an amendment;

- - as a result of the exercise, (A) it purchases class A-1 certificates and class
  B-1 certificates having in each case an aggregate certificate principal
  balance or an aggregate notional amount, respectively, of at least $5,000,000
  or, if less, the remaining aggregate certificate principal balance of the
  class A-1 certificates and the remaining aggregate certificate notional amount
  of the class B-1 certificates, and (B)(I) unless the option holder has
  exercised all call options held by it, the aggregate certificate principal
  balance of the class A-1 certificates and the aggregate certificate notional
  amount of the class B-1 certificates subject to call options, held by the
  option holder that have not been exercised is not less than $5,000,000,
  respectively, and (II) the remaining aggregate certificate principal balance
  of the class A-1 certificates and the remaining aggregate certificate notional
  amount of the class B-1 certificates, if greater than zero, is not less than
  $5,000,000, respectively.

If call options are held by two or more affiliated persons, then all options
held or exercised by those affiliated persons will be treated as being held or
exercised by a single option holder for purposes of the above requirements.

If a holder of call options exercises its call options, the option agent will
remit the amount of the call price received to the trustee for payment to the
certificate holders whose certificates are called. If call options are exercised
with respect to less than all the class A-1 certificates, the class A-1
certificates to be purchased will represent a pro rata portion of the class A-1
certificates held by each certificate holder, except that purchases of a
fraction of a single class A-1 certificate will not be made, and the trustee may
round up or down to avoid such fractional purchases.

If a holder of call options exercises options, the trustee will automatically
exchange the certificates acquired by the option holder under the options,
simultaneously with the delivery of the certificates to the call option holder,
for AOL Time Warner debentures with an aggregate principal amount equal to the
aggregate certificate principal balance of the class A-1 certificates acquired.
The called certificates will then be cancelled by the trustee, and interest at
the pass-through rate will cease to accrue, without

                                                                           S- 29

DESCRIPTION OF THE CERTIFICATES
- --------------------------------------------------------------------------------

the need for any further action by you. If you are holding your certificates in
definitive physical form, your called certificates will be cancelled without
your taking any further action, but you will not receive the purchase price for
your certificates until you deliver your called certificates to the trustee.

Unless the option exercise was made in connection with a tender offer, if an
option holder has not paid the purchase price to the option agent by 10:00 a.m.
(New York City time) on the date specified for settlement in the notice of
exercise, the option holder's notice of exercise will automatically expire. If
the option exercise was made in connection with a tender offer, if the trustee
has not received payment of the tender price from AOL Time Warner (or another
purchaser of the AOL Time Warner debentures in a tender offer, if applicable)
under all of the exercised call options (or with respect to the portion of the
call options deemed exercised, if less than all AOL Time Warner debentures
tendered by the trustee are purchased in the tender offer) in immediately
available funds, no later than 10:00 a.m. (New York City time) on the later of
(i) the date specified for settlement in the notice of exercise, or (ii) the
earlier to occur of the date immediately following the date on which the tender
offer is consummated or the date on which it expires unconsummated, the option
holder's notice of exercise will automatically expire. In each case, upon the
expiration of the holder's notice of exercise, none of the option holder, the
option agent or the trustee will have an obligation with respect of the notice
of exercise, and the expiration of the notice to exercise will in no way affect
the option holder's right to deliver a notice to exercise at a later date.

Each holder of a call option will have the right to assign its rights under the
call option in accordance with its terms to any person other than the depositor.

TERMINATION OF BOOK-ENTRY REGISTRATION IN CONNECTION WITH SUSPENSION OF
SECURITIES EXCHANGE ACT REPORTING BY AOL TIME WARNER
If AOL Time Warner ceases to have a class of securities listed on a national
securities exchange or held of record by 300 or more holders, it could elect to
suspend its reporting requirements under the Securities Exchange Act. In that
event, AOL Time Warner will no longer be required to make available under the
Securities Exchange Act the public information referred to above under
"Description of the AOL Time Warner Debentures--Available Information." If this
happens, then, unless the trust has earlier suspended its own Securities
Exchange Act reporting requirements, the class A-1 certificates will be removed
from the DTC book-entry system, and definitive certificates representing the
class A-1 certificates will be issued to the beneficial owners of the class A-1
certificates. In addition, the trustee will notify AOL Time Warner that the AOL
Time Warner debentures are held pursuant to the trust agreement and that the
holders of the certificates constitute record holders of the AOL Time Warner
debentures. The issuance of definitive class A-1 certificates is intended to
increase the likelihood that there will then be more than 300 holders of record
of the AOL Time Warner debentures, requiring AOL Time Warner to resume filing
Securities Exchange Act reports, in light of Rule 12g5-1(b)(1) under the
Securities Exchange Act, which requires an issuer of underlying securities with
actual knowledge that those underlying securities are held pursuant to a trust
agreement to treat holders of record of certificates issued by the trust as
holders of record of the underlying securities. There is, however, no certainty
that the issuance of definitive certificates will cause there to be more than
300 holders of record of the AOL Time Warner debentures.

If distributing definitive class A-1 certificates does not cause AOL Time Warner
to resume filing Securities Exchange Act reports, then as long as the trust is
required to file reports under the Securities Exchange Act, the trust will
provide, in the trust's own Securities Exchange Act reports, quarterly and
annual financial statements and other information of the type required to be
filed on Form 8-K under the Securities Exchange Act with respect to AOL Time
Warner, to the extent the information is then available to the trust. The
trustee has agreed to request this information from AOL Time Warner, but will
have no duty to make any other attempts to obtain the information if it is not
voluntarily

S- 30

DESCRIPTION OF THE CERTIFICATES
- --------------------------------------------------------------------------------

provided by AOL Time Warner upon request. It is unlikely that AOL Time Warner
will voluntarily provide such information to the trust at such time, and the
liquidity of your certificates may be adversely affected by the lack of publicly
available information about the financial condition and business of AOL Time
Warner. See "Risk Factors" above.

DISTRIBUTIONS
On each distribution date, the trustee will distribute the funds, if any,
received in respect of principal and interest on the AOL Time Warner debentures
on that date (which will also be an AOL Time Warner debentures interest payment
date) as follows:

- - all amounts received in respect of interest shall be applied to make pro rata
  distributions of interest to the holders of the class A-1 certificates at the
  pass-through rate of 7.625% on their certificate principal balances and the
  holders of the class B-1 certificates at the pass-through rate of 0.075% on
  their certificate notional amounts;

- - all amounts received in respect of principal shall be distributed to the
  holders of the class A-1 certificates.

REDEMPTIONS AND TENDER OFFERS
As described above under "Description of the AOL Time Warner
Debentures--Optional Redemption", AOL Time Warner has the right to redeem the
AOL Time Warner debentures at any time, and may make tenders for, or other
unscheduled repayments on or repurchases of, the AOL Time Warner debentures. If
AOL Time Warner redeems some or all of the AOL Time Warner debentures, then a
corresponding portion of the certificates will be redeemed. Where there is a
partial redemption of the AOL Time Warner debentures, class A-1 certificates and
class B-1 certificates will be selected for redemption pro rata based on the
certificate principal balance of the class A-1 certificates and the certificate
notional amount of the class B-1 certificates, except that no fractional
repurchases of certificates will be made. Assuming AOL Time Warner makes
payments when due, on the third business day after the trustee receives the
proceeds of any full or partial redemption of the AOL Time Warner debentures,
the proceeds will be distributed, as between the class A-1 certificates and the
class B-1 certificates selected for redemption, as follows:

- - proceeds in respect of interest will be allocated to the holders of the class
  A-1 certificates and the class B-1 certificates pro rata based on the interest
  accrued but not paid through the redemption date on the certificate principal
  balance of the class A-1 certificates and the certificate notional amount of
  the class B-1 certificates, respectively.

- - proceeds in respect of principal, and premium, if any, will be allocated to
  all holders of the class A-1 certificates.

- - no amounts received in respect of principal or premium will be distributed to
  the holders of the class B-1 certificates.

As the holder of a class A-1 certificate that is redeemed, you will receive the
following distributions in respect of such proceeds:

- - a distribution of the amounts received in respect of accrued but unpaid
  interest at the pass-through rate of 7.625% per annum through the redemption
  date;

- - a distribution of the amounts received in respect of principal in the amount
  of the certificate principal balance of the class A-1 certificate on such day;
  and

- - a distribution of your pro rata portion of the amounts, if any, distributed to
  the holders of the class A-1 certificates in respect of premium on the AOL
  Time Warner debentures on such day.

                                                                           S- 31

DESCRIPTION OF THE CERTIFICATES
- --------------------------------------------------------------------------------

If the AOL Time Warner debentures are redeemed, the call option holders are
likely to call the certificates to be redeemed and, as a result, to receive most
or all the premium described above.

If AOL Time Warner (or another third party, in the case of a tender offer)
announces its intention to tender for or otherwise make an unscheduled repayment
on or repurchase of the AOL Time Warner debentures, the trustee will be required
not to accept any such tender offer or unscheduled repayment or repurchase
offer, except in connection with the exercise of call options, as set forth
above or, if the option is not exercised, upon the unanimous vote of the class
A-1 certificate holders. The holders of the call options will have the right to
purchase your class A-1 certificates at a call price equal to the certificate
principal balance of your class A-1 certificates plus any accrued but unpaid
interest (and, if this event occurs before June 21, 2007, the "early call
premium amount" described under "Description of the Certificates--The Class A-1
Certificates--The Call Options"). This "early call premium amount" may be less
than the premium payable by AOL Time Warner upon a redemption of, tender for or
other repurchase of the AOL Time Warner debentures.

Amounts received on the AOL Time Warner debentures on each distribution date
will be sufficient to make all required distributions to holders of the
certificates, in the absence of an AOL Time Warner debentures default or the
incurrence of additional payment obligations by the trust. We do not expect that
the trust will incur any such additional payment obligations. The holders of the
certificates will only have the rights described under "Description of the Trust
Agreement."

If there is an AOL Time Warner debentures default and amounts due in respect of
principal on the AOL Time Warner debentures are accelerated, the provisions
above regarding redemptions, tender offers or unscheduled repayments will not
apply. Instead, distributions in respect of payments or property, if any,
received by the trustee after the acceleration of the AOL Time Warner debentures
will be made as described under "Description of the Trust Agreement--AOL Time
Warner Debentures Defaults" below.

THE CLASS B-1 CERTIFICATES

The class B-1 certificates are not being offered by this prospectus supplement.
The class B-1 certificates will be issued in minimum notional denominations of
$25.00 and multiples of $25.00 and the aggregate certificate notional amount of
all the class B-1 certificates will be $50,000,000. Each class B-1 certificate
will represent the right to receive a distribution allocable to interest only,
on each distribution date or on any earlier redemption date for the AOL Time
Warner debentures, at the pass-through rate of 0.075% per annum on the
outstanding certificate notional amount. The holders of the class B-1
certificates will not be entitled to receive any distributions allocable to
principal or premium. See "Description of the Certificates--Stripped
Certificates" in the attached prospectus. If call options are exercised with
respect to less than all the class B-1 certificates, the class B-1 certificates
to be purchased will represent a pro rata portion of the class B-1 certificates
held by each certificate holder. Purchases of a fraction of a single class B-1
certificate will not be permitted.

The final distribution date on the class B-1 certificates will be the same as
the final distribution date on the class A-1 certificates.

The right of the holders of the class B-1 certificates to receive distributions
allocable to interest will rank pari passu with the right of the class A-1
certificates to receive distributions allocable to interest.

The class B-1 certificates will initially be issued to the depositor. The
depositor will sell the class B-1 certificates to UBS Warburg LLC, which intends
to sell them privately to one or more investors in accordance with the
restrictions contained in the trust agreement. The class B-1 certificates will
be subject to call options substantially similar to the call options on the
class A-1 certificates.

S- 32

DESCRIPTION OF THE CERTIFICATES
- --------------------------------------------------------------------------------

VOTING RIGHTS

At all times, the outstanding class A-1 certificates will bear all of the voting
rights applicable to all the certificates; the outstanding class B-1
certificates will not have any voting rights, except with respect to any
amendment to the trust agreement that would materially adversely affect the
holders of the class B-1 certificates, which must be approved by class B-1
certificate holders holding a majority of the voting rights of the class B-1
certificates.

Each class A-1 certificate of $25.00 in certificate principal balance will bear
one vote. For the limited purpose of approving amendments to the trust agreement
that would materially adversely affect the class B-1 certificates, each class
B-1 certificate of $25.00 in certificate notional amount will bear one vote.
Class A-1 certificate holders have no right to waive compliance by the depositor
or the trustee with any restrictive provision of the trust agreement or to waive
any default under the trust agreement.

A certificate will be considered "outstanding" so long as it is held by any
person other than (and is not pledged to) the depositor, the trustee (in its
individual capacity) or any of their respective affiliates.

ADDITIONAL AOL TIME WARNER DEBENTURES

From time to time, the trust may acquire additional AOL Time Warner debentures
in a principal amount of not less than $5,000,000, in which case additional
class A-1 certificates and class B-1 certificates will be issued in the same
relative proportions as the class A-1 certificates and class B-1 certificates
issued on the closing date. These new certificates will have an aggregate
certificate principal balance or certificate notional amount, as applicable,
equal to 100% of the principal amount of the additional AOL Time Warner
debentures. Any additional certificates issued will have the same priority,
right to payments and voting rights as the certificates of the same class issued
on the closing date, and any additional certificates will be subject to call
options on the same terms as the call options described in this prospectus
supplement.

The depositor will agree that if it does cause the trust to issue additional
certificates, the depositor will either resell the call options on the new
certificates to the same entities that then hold the call options on the
existing certificates, and in the same proportions as those entities hold the
existing call options, or to any other persons that are designated by those
entities, or the depositor will ensure that the issuance of the new certificates
and the related options will not affect the right of the existing option holders
to exercise their options at any time as described under "--The Call Options"
above.

                                                                           S- 33

The certificates will be issued pursuant to the trust agreement to be dated as
of June 21, 2002, between the depositor and The Bank of New York, as trustee and
option agent, a form of which is filed as an exhibit to the registration
statement of which the attached prospectus forms a part. A current report on
Form 8-K containing a copy of the trust agreement as executed will be filed by
the trustee with the SEC following the closing date. The assets of the trust
created under the trust agreement will consist of:

- - the AOL Time Warner debentures (exclusive of interest accrued from and
  including April 8, 2002, to but excluding the closing date, which has been
  retained by the depositor);

- - all payments on or collections in respect of the AOL Time Warner debentures
  due after the closing date; and

- - any other proceeds of the AOL Time Warner debentures.

You should refer to the attached prospectus for additional important information
regarding the trust, the trust agreement and the certificates. The material
terms of the trust agreement are summarized below and in the attached
prospectus. These summaries are not complete and are subject to the detailed
provisions contained in the trust agreement. You should refer to the form of
trust agreement in order to obtain a full understanding of its provisions.

CERTAIN PAYMENTS TO THE DEPOSITOR

The interest accrued on the AOL Time Warner debentures from and including April
8, 2002, to but excluding the closing date will be retained by the depositor and
will not be transferred to the trust with the AOL Time Warner debentures. On
November 1, 2002, the trustee will pay the accrued interest to the depositor to
the extent received from AOL Time Warner.

THE TRUSTEE

The Bank of New York, a New York banking corporation, will act as trustee of the
trust and as option agent. The trustee's corporate trust offices are located at
5 Penn Plaza, New York, New York 10001 and its telephone number is 212-896-7110.

The trust agreement will provide that the trustee and its directors, officers,
employees and agents will be indemnified by the depositor as described in the
attached prospectus under "Description of the Trust Agreement--Matters Regarding
the Trustee." However, the depositor is not required to reimburse any expense or
indemnify the trustee against any loss, liability or expense that is incurred by
the trustee through the trustee's own negligent action, the trustee's own
negligent failure to act or willful misconduct, or bad faith in the performance
of the trustee's duties under the trust agreement.

Except as described below under "--AOL Time Warner Debentures Defaults", the
trustee's fees and expenses will all be paid by the depositor pursuant to a
separate agreement between the depositor and the trustee. UBS Americas, Inc.,
the depositor's parent, has agreed to indemnify the trustee for any losses
arising from the failure of the depositor to make payments to the trustee when
due under the separate agreement. Failure by the depositor (or UBS Americas,
Inc. as indemnitor) to pay, reimburse or indemnify the trustee will not entitle
the trustee to any payment, reimbursement or indemnification from the trust.
Except as described below under "--AOL Time Warner Debentures Defaults," any
unpaid, unreimbursed or unindemnified amounts will not be borne by the trust and
will not constitute a claim against the trust.

DESCRIPTION OF THE TRUST AGREEMENT
- --------------------------------------------------------------------------------

AOL TIME WARNER DEBENTURES DEFAULTS

If there is an event of default on any AOL Time Warner debentures, the trustee
will give notice to the registered holders of the class A-1 certificates and to
the option agent within five business days after the trustee has actual
knowledge of the default. The notice will identify the AOL Time Warner
debentures, and will set forth (a) the date and nature of the default, (b) the
amount of the interest, principal or premium in default, if such default is a
payment default, and (c) any other information that the trustee may deem
appropriate.

If there is a default on the AOL Time Warner debentures, the trustee has agreed
to proceed against AOL Time Warner on behalf of the certificate holders to
enforce the AOL Time Warner debentures or otherwise to protect the interests of
the certificate holders (including, in the trustee's discretion, voting to
accelerate the AOL Time Warner debentures). The trustee is entitled to
indemnification for so proceeding under the indemnity granted to the trustee by
the depositor in the trust agreement, which is guaranteed by UBS Americas, Inc.
In addition, under the trust agreement, the trustee will be entitled to recover
its reasonable expenses of proceeding against AOL Time Warner out of the
proceeds of trust assets.

Notwithstanding the duty of the Trustee to enforce the AOL Time Warner
debentures or otherwise protect the interests of certificate holders after an
AOL Time Warner debentures default, the holders of the class A-1 certificates
representing a majority of the voting rights on the class A-1 certificates will
be entitled to direct the trustee in any such proceeding, subject to the
trustee's receipt of satisfactory indemnity, including instructing the trustee
to stop proceeding against AOL Time Warner and to sell the AOL Time Warner
debentures instead.

METHOD OF LIQUIDATION
If following an AOL Time Warner debentures default, the trustee receives any
money or other property in respect of the AOL Time Warner debentures (including
from the sale of the AOL Time Warner debentures), or actual notice that money or
other property will be received, the trustee will promptly give notice to the
registered holders of the class A-1 certificates that are then outstanding and
unpaid, and to the option agent. The notice will state that, not later than 30
days after the receipt of the money or other property, the trustee will allocate
and distribute the money or other property to the holders of the class A-1
certificates pro rata by certificate principal balance (after deducting the
costs incurred in connection therewith). The trustee will make this distribution
after payment of any payment obligations of the trust.

Any property other than cash received in respect of the AOL Time Warner
debentures will be distributed in kind, except that property will be liquidated
by the trustee, and the proceeds distributed in cash, to the extent necessary to
avoid distribution of fractional securities or other fractional property to the
class A-1 certificate holders.

If a default under the AOL Time Warner indenture occurs and is continuing and if
the trustee is so directed by holders representing a majority of the voting
rights of the outstanding class A-1 certificates, the trustee will vote the AOL
Time Warner debentures in favor of directing, or take other action as may be
appropriate to direct, the trustee of the AOL Time Warner debentures to
accelerate the AOL Time Warner debentures by declaring the unpaid principal
amount of the AOL Time Warner debentures and any accrued and unpaid interest on
the AOL Time Warner debentures to be due and payable.

                                                                           S- 35

DESCRIPTION OF THE TRUST AGREEMENT
- --------------------------------------------------------------------------------

LIMITATION ON RIGHTS OF ACTION

A holder of a class A-1 certificate will have the right to institute a
proceeding against AOL Time Warner with respect to the AOL Time Warner
debentures only if:

- - the holder previously has given to the trustee written notice of a continuing
  breach of the AOL Time Warner debentures;

- - the holder or holders of certificates evidencing not less than 25% of the
  outstanding class A-1 certificates have requested in writing that the trustee
  institute the proceeding in its own name as trustee;

- - the trustee has for 15 days not instituted the proceeding; and

- - no direction inconsistent with the written request has been given to the
  trustee during the 15-day period by the holders certificates evidencing a
  majority of the outstanding class A-1 certificates.

The trustee will not be required to take any action unless the holder or holders
of class A-1 certificates have offered the trustee reasonable indemnity for its
costs, expenses and liabilities.

VOTING OF AOL TIME WARNER DEBENTURES; MODIFICATION OF AOL TIME WARNER INDENTURE

Except as described below, other than after the occurrence and during the
continuation of an AOL Time Warner debentures default, the trustee has agreed
not to consent to any amendment, modification or supplement to the AOL Time
Warner debentures, or any solicitation for any other action.

If the trustee receives a request from DTC, the AOL Time Warner debentures
trustee or AOL Time Warner for its consent to any amendment, modification or
waiver of the AOL Time Warner debentures, the AOL Time Warner indenture or any
other documents relating to the AOL Time Warner debentures, or receives any
other solicitation for any action with respect to the AOL Time Warner
debentures, the trustee will mail notice of the proposed amendment,
modification, waiver or solicitation to each holder of a call option on the
class A-1 certificates and, ten (10) business days after notice is mailed to
holders of those call options, to each Class A-1 certificate holder of record,
as of that date. The trustee will request instructions from the class A-1
certificate holders as to whether or not to consent to or vote to accept the
amendment, modification, waiver, or solicitation, and will vote a principal
amount of the AOL Time Warner debentures equal to the certificate principal
balance of the class A-1 certificates whose holders have given the trustee
instructions to vote ("pass-through voting"). Provided that no holder of a call
option on the class A-1 certificates has given notice of its exercise of the
call option and has paid the purchase price within such ten (10) business day
period, the trustee will consent or vote, or refrain from consenting or voting,
in the proportion in which the class A-1 certificate holders instruct the
trustee to vote as of the date determined by the trustee prior to the date on
which the consent or vote is required. However, if the holder of any call option
on the class A-1 certificates has given notice of its exercise of the call
option and has paid the purchase price, the trustee will vote a corresponding
proportion of the AOL Time Warner debentures as directed by the call option
holder, and not as directed by the applicable class A-1 certificate holders.

Notwithstanding anything to the contrary in this prospectus supplement, the
trustee will at no time vote or consent to any matter:

- - unless the vote or consent would not, based on an opinion of counsel,
  adversely affect the intended classification of the trust as a grantor trust
  for federal income tax purposes;

- - that would amend the AOL Time Warner indenture or AOL Time Warner debentures
  to alter the timing or amount of any payment on the AOL Time Warner
  debentures, except at the direction of the holders of all the outstanding
  class A-1 certificates or, if and to the extent that the holder of any

S- 36

DESCRIPTION OF THE TRUST AGREEMENT
- --------------------------------------------------------------------------------

  call options on the class A-1 certificates has given notice of its exercise of
  call options and has paid the purchase price, of that call option holder; or

- - that would result in the exchange or substitution of any of the outstanding
  AOL Time Warner debentures pursuant to a plan for the refunding or refinancing
  of such AOL Time Warner debentures, except at the direction of the holders of
  all the outstanding class A-1 certificates or, if and to the extent that the
  holder of any call options on the class A-1 certificates has given notice of
  its exercise of call options and has paid the purchase price, of that call
  option holder.

If an offer is made by AOL Time Warner to issue new obligations in exchange and
substitution for any of the AOL Time Warner debentures, pursuant to a plan for
the refunding or refinancing of the AOL Time Warner debentures, or any other
offer is made for the AOL Time Warner debentures, the trustee will notify the
holders of the call options on the class A-1 certificates. If any option holder
on the class A-1 certificates exercises its call options, then the trustee must
act in accordance with the option holder's instructions. If the holders of the
call options on the class A-1 certificates do not exercise their call options
within ten (10) business days after notice is mailed to holders of call options,
the trustee will notify the registered holders of the class A-1 certificates and
must reject the offer unless directed to accept it by holders of 100% of the
outstanding class A-1 certificates in which case the trustee will accept the
offer provided that the trustee has received an opinion of counsel to the effect
that any such exchange will not (i) adversely affect the intended classification
of the trust as a grantor trust for federal income tax purposes, or (ii) result
in a deemed exchange of the AOL Time Warner debentures or the certificates for
federal income tax purposes. If and to the extent that call options have been
exercised in connection with the tender offer, the trustee will be required to
tender AOL Time Warner debentures, as described under "Description of the
Certificates--The Class A-1 Certificates--The Call Options" above.

                                                                           S- 37


- --------------------------------------------------------------------------------

United States Federal Income Tax Consequences

The following is a general discussion of the material United States federal
income tax consequences of the purchase, ownership and disposition of the
certificates by an initial holder of certificates. This summary is based upon
the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code"), as
well as Treasury regulations and administrative and judicial rulings and
decisions currently in effect, all of which are subject to change, possibly on a
retroactive basis. Legislative, judicial and administrative changes may occur,
possibly with retroactive effect, that could alter or modify the continued
validity of the statements and conclusions set forth in this section.

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. For
example, it generally addresses only tax issues relevant to original purchasers
of the certificates at the initial offering price who are beneficial owners of
the certificates. The discussion assumes that the certificates are held as
"capital assets" (generally, property held for investment) within the meaning of
section 1221 of the Internal Revenue Code. The discussion does not address
various possible tax considerations that may be relevant to investors subject to
special rules, such as investors that are regulated investment companies, banks,
insurance companies, tax-exempt organizations, dealers in securities or
currencies, mutual funds, REITs, cash method taxpayers, S corporations, estates
and trusts, investors that hold the certificates as part of a hedging, straddle
or integrated or conversion transaction, investors that hold certificates as
part of a conduit arrangement subject to regulations issued pursuant to section
7701(l) of the Internal Revenue Code, or investors whose functional currency is
not the United States dollar. In addition, this discussion does not address
alternative minimum tax consequences or the indirect effects on the holders of
equity interests in a certificate holder, and does not address investors that
are not "United States persons" (as defined below), except to the extent
expressly discussed below under "--Foreign Certificate Holders."

You should consult your tax advisor to determine the federal, state, local and
other tax consequences of the purchase, ownership and disposition of the
certificates.

The following assumes that the AOL Time Warner debentures are treated as debt
for federal income tax purposes.

TAX CLASSIFICATION OF THE TRUST

CLASSIFICATION OF THE TRUST
Sidley Austin Brown & Wood LLP, special federal tax counsel to the depositor and
the trust, has delivered an opinion to the effect that, for United States
federal income tax purposes, the trust will not be classified as an association
or publicly traded partnership taxable as a corporation. Although the
classification of the trust is not free from doubt, pursuant to the trust
agreement the trustee and the holders will treat the trust as a grantor trust
for federal income tax purposes. If the trust is treated as a grantor trust, the
holder of a certificate will be treated as the owner of a pro rata undivided
interest in the trust assets subject to the call option. Information returns or
reports sent to certificate holders and the IRS will be based on the trust being
classified as a grantor trust for federal income tax purposes in the absence of
statutory or authoritative judicial or regulatory clarification or change to the
contrary. As a grantor trust, the trust will not be subject to federal income
tax, and each certificate holder will be subject to federal income taxation as
if it owned directly the portion of the trust assets allocable to the
certificates, and as if it paid directly its share of expenses, if any, paid by
the trust.

You should be aware that no rulings have been sought from the IRS with respect
to the classification of the trust and that opinions of counsel are not binding
on the IRS or the courts. Accordingly, there can be no absolute assurance that
the IRS will agree that the trust should be treated as a grantor trust.

S- 38

UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
- --------------------------------------------------------------------------------

POSSIBLE RECHARACTERIZATION OF THE TRUST AS A PARTNERSHIP
If the trust were classified as a partnership, rather than as a grantor trust,
the trust would not be subject to federal income tax and certificate holders
would be treated as owning partnership interests rather than as owning direct
interests in the trust assets. Each item of income, gain, loss and deduction
generated as a result of the ownership of the AOL Time Warner debentures by the
trust would be passed through to the certificate holders as the partners of the
partnership according to their respective interests therein. The amount of
income reportable by the certificate holders as partners in such partnership
could differ from the amount of income reportable by the certificate holders as
holders of an interest in a grantor trust. In addition, characterization of the
trust as a partnership for federal income tax purposes may also have adverse
state or local tax consequences for certificate holders. Certificate holders
should consult their own tax advisors regarding the effect that any
recharacterization may have upon them.

The trust agreement will provide that if the trust is classified as a
partnership for federal income tax purposes, the trust will make an election
under section 761 of the Internal Revenue Code to be excluded from the
provisions of Subchapter K of the Internal Revenue Code governing the treatment
of partnerships. If the trust makes an effective election out of Subchapter K of
the Internal Revenue Code, the treatment of certificate holders will be similar
whether the trust is classified as a grantor trust or a partnership. However,
the eligibility of the trust to make the election is not free from doubt.

The remainder of this discussion assumes that the trust is properly classified
as a grantor trust or that, if it were to be reclassified as a partnership its
election to be excluded from Subchapter K of the Internal Revenue Code would be
effective.

INCOME OF U.S. CERTIFICATE HOLDERS
For federal income tax purposes, the class A-1 certificates represent a pro rata
undivided interest in the principal and a portion of the interest payable on the
AOL Time Warner debentures, subject to the call option. Although not entirely
clear, it appears that these two positions may, at the election of the taxpayer,
be integrated and treated as a single "synthetic" debt instrument under Treasury
Regulation Section 1.1275-6. The terms of the certificates require each initial
certificate holder to make an integration election with respect to the
certificates and to therefore treat the certificates as a single "synthetic"
debt instrument for all U.S. federal income tax purposes. The only action an
initial certificate holder needs to take in order to make an integration
election is for it to retain in its books and records certain information with
respect to the integration election that will be sent to each initial
certificate holder along with the confirmation of the certificate holder's
purchase of the certificates. The terms of the certificates do not require a
secondary purchaser of certificates to make an integration election and thus
such a purchaser should consult with its tax advisor as to whether it should
make an integration election with respect to its certificates.

For a taxpayer that takes all steps necessary to make the election effective,
under the rules applicable to synthetic debt instruments, neither the interest
in the AOL Time Warner debentures nor the call option would be generally subject
to the rules that would apply on a separate basis to each component. One
consequence of such an election is that the taxpayer would be required to report
income on the class A-1 certificates under the accrual method of accounting,
regardless of the method that the taxpayer generally uses. If no effective
election is made, the tax treatment of the components would be determined
separately. Nevertheless, the difference between treating the class A-1
certificates as evidencing ownership of an integrated, synthetic debt instrument
rather than as the ownership of two separate component positions is not
anticipated to be material. Certificate holders are urged to consult their own
tax advisors regarding the foregoing.

To the extent that the principal amount of a class A-1 certificate exceeds the
certificate's purchase price by more than a de minimus amount, the holder's
interest therein will be treated as purchased with

                                                                           S- 39

UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
- --------------------------------------------------------------------------------

"original issue discount." See the discussion below under "Interest Income and
Original Issue Discount." Conversely, to the extent that the purchase price of a
class A-1 certificate exceeds the certificate's principal amount, the holder's
interest therein will be treated as purchased with "bond premium," which may be
amortized based on a constant yield method over the remaining term of the
synthetic debt instrument. See the discussion below under "Bond Premium."

Interest Income and Original Issue Discount.  The class A-1 certificates
represent, in part, an undivided interest in the principal payable on the AOL
Time Warner debentures and a portion of the interest amount of the AOL Time
Warner debentures. In effect, a portion of the interest on the AOL Time Warner
debentures has been "stripped" off the AOL Time Warner debentures. Pursuant to
the tax rules applicable to stripped debt obligations, on each date a
certificate is purchased, the security backing the class A-1 certificate would
be treated as newly issued, evidencing the ownership of an interest in a newly
issued debt instrument that may have original issue discount. For federal income
tax information reporting purposes, based on the foregoing, each certificate
holder will be required to report on its federal income tax return, its share of
interest income earned by the trust with respect to the AOL Time Warner
debentures. If, however, the IRS were to challenge this position successfully,
the class A-1 certificates would represent an interest in securities having
original issue discount.

The original issue discount on a certificate will be the excess, if any, of the
certificate's principal amount over its purchase price. Any purchaser who
purchases a certificate at more than a de minimis amount of discount would be
required to accrue income on the certificate based on a constant yield method
without regard to the receipt of cash.

Bond Premium.  If a certificate holder is treated as acquiring a class A-1
certificate at a premium, which is a price in excess of the certificate's
principal amount, such premium will be amortizable by the holder as an offset to
interest income (with a corresponding reduction in the certificate holder's
basis). The certificate holder may elect under section 171 of the Internal
Revenue Code to amortize the portion of the premium allocable to the certificate
using a constant yield method over the term of such certificate. Any such
election will also apply to all debt instruments held by the certificate holder
during the year in which the election is made and to all debt instruments
acquired thereafter.

MODIFICATION OR EXCHANGE OF TRUST ASSETS
Depending upon the circumstances, it is possible that a modification of the
terms of the trust assets, or a substitution of other assets for the trust
assets following a default on the trust assets, would be a taxable event to
certificate holders on which they would recognize gain or loss.

TREATMENT OF THE TRUST'S FEES AND EXPENSES
All of the trust's fees and expenses will be paid by the depositor. Therefore,
the trust intends to take the position that the payment of such fees and
expenses should not cause a certificate holder to recognize any items of income
or deduction for federal income tax purposes. However, if the payment of such
fees and expenses is regarded as paid for the benefit of the certificate
holders, certificate holders may be required to recognize additional gross
income based on their proportionate share of such fees and expenses. A
certificate holder will generally be entitled to deduct, consistent with its
method of accounting, its share of such fees and expenses paid or incurred by
the trust as provided in section 162 or 212 of the Internal Revenue Code. If a
certificate holder is an individual, estate, trust or pass-through entity that
has partners that are individuals, the deduction for his or her share of fees
will be a miscellaneous itemized deduction that may be disallowed in part or in
whole for purposes of the regular income tax or the alternative minimum tax.

PURCHASE AND SALE OF A CERTIFICATE
If a certificate is sold or exchanged, including pursuant to the exercise of the
call option, gain or loss will be recognized equal to the difference between the
amount realized from the sale or exchange and

S- 40

UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
- --------------------------------------------------------------------------------

the certificate holder's adjusted tax basis in its certificate. A certificate
holder's adjusted tax basis in a certificate generally will equal the cost of
the certificate, increased by any amounts of undistributed taxable income
recognized by a certificate holder (for example original issue discount) and
reduced by any amortizable premium and any payments other than payments of
interest on a trust asset made on the certificate. Any gain or loss recognized
on the sale or exchange of a certificate will generally be long-term capital
gain or loss if the certificate had been held at the time of disposition for
more than one year and if the certificate holder made the integration election
described above with respect to its certificates. Otherwise, any such gain or
loss would likely be short-term capital gain or loss.

INFORMATION REPORTING AND BACKUP WITHHOLDING
Payments made on the certificates and proceeds from the sale of the certificates
will not be subject to "backup" withholding tax unless, in general, the
certificate holder fails to comply with specified identification procedures and
is not an exempt recipient under applicable provisions of the Internal Revenue
Code. In general, such payments will be subject to information reporting unless
the certificate holder is an exempt recipient or otherwise establishes an
exemption by complying with the specified identification procedures under
applicable provisions of the Internal Revenue Code. Any amounts withheld under
the backup withholding rules will generally be allowed as a refund or credit
against your federal income tax liability, provided that the required
information is furnished to the IRS.

Subsequent certificate holders should be aware that information reports, even if
otherwise accepted as accurate by the IRS, will in any event be accurate only as
to initial certificate holders that bought their certificates at the
representative initial offering price used in preparing the reports.

FOREIGN CERTIFICATE HOLDERS
A "foreign certificate holder" is any certificate holder that is not a "United
States person." A "United States 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 any of its political subdivisions,
an estate the income of which is includible in gross income for United States
federal income tax purposes, regardless of its source, or a trust with respect
to which a court within the United States is able to exercise primary
supervision over its administration and one or more United States fiduciaries
have the authority to control all of its substantial decisions.

A foreign certificate holder who is holding a certificate on its own behalf will
generally not be subject to United States federal withholding taxes on payments
made on a certificate, unless such foreign certificate holder is a direct or
indirect 10% or greater shareholder of AOL Time Warner or a controlled foreign
corporation related to AOL Time Warner. To establish an exemption from
withholding, a foreign certificate holder must certify under the penalties of
perjury that it is not a United States person and provide certain information
specified under the Treasury regulations, including its name, address and
taxpayer identification number, if any. Foreign certificate holders are urged to
consult their own tax advisors concerning the application of the certification
requirements with respect to the Treasury regulations.

STATE AND OTHER TAX CONSEQUENCES
In addition to the federal income tax consequences described above, certificate
holders should consider the state, local and foreign tax consequences of the
acquisition, ownership and disposition of the certificates. State, local and
foreign tax law may differ substantially from the corresponding federal tax law,
and the discussion above does not purport to describe any aspect of the tax law
of any state or other jurisdiction. Therefore, we recommend that prospective
investors consult their tax advisors with respect to such matters.

                                                                           S- 41


- --------------------------------------------------------------------------------

ERISA Considerations

The Employee Retirement Income Security Act of 1974, as amended ("ERISA") and
the Internal Revenue Code impose various requirements on "employee benefit
plans" (as defined in section 3(3) of ERISA), "plans" (as defined in section
4975(e)(1) of the Internal Revenue Code, other than a governmental or church
plan described in section 4975(g)(2) or (3) of the Internal Revenue Code) (each,
a "plan") and on persons that are fiduciaries with respect to plans in
connection with the investment of the assets of a plan. For purposes of this
discussion, plans may include individual retirement accounts and annuities,
Keogh plans and separate accounts and collective investment funds, including as
applicable, insurance company general accounts, in which other plans are
invested.

Governmental plans and, if they have not made an election under section 410(d)
of the Internal Revenue Code, church plans are not subject to ERISA
requirements. Accordingly, assets of those plans may be invested in the
certificates without regard to the considerations described below in this "ERISA
Considerations" section, subject to the provisions of other applicable federal
and state law. Any of those plans that is qualified and exempt from taxation
under sections 401(a) and 501(a) of the Internal Revenue Code, however, is
subject to the prohibited transaction rules in section 503 of the Internal
Revenue Code.

ERISA imposes general fiduciary requirements on a fiduciary that is investing
the assets of a plan, including investment prudence and diversification and
compliance with the investing plan's governing documents. Section 406 of ERISA
and section 4975 of the Internal Revenue Code also prohibit a broad range of
transactions involving the assets of a plan and a "party in interest" (as
defined in section 3(14) of ERISA) or a "disqualified person" (as defined in
section 4975(e)(2) of the Internal Revenue Code) with respect to that plan,
unless a statutory or administrative exemption exists. Parties in interest or
disqualified persons that participate in a prohibited transaction may be subject
to an excise tax imposed under section 4975 of the Internal Revenue Code or a
penalty imposed under section 502(i) of ERISA, unless a statutory or
administrative exemption is available. In addition, the persons involved in the
prohibited transaction may have to cancel the transaction and pay an amount to
the affected plan for any losses realized by that plan or profits realized by
those persons. In addition, if the owner or beneficiary of an individual
retirement account engages in a prohibited transaction, the individual
retirement account may be disqualified, which would result in adverse tax
consequences to the owner or beneficiary of the account.

PLAN ASSET REGULATIONS

A plan's investment in the certificates may cause the underlying assets of the
trust to be deemed assets of that plan. Section 2510.3-101 of the Department of
Labor regulations (the "plan asset regulations") provides that when a plan
acquires an "equity interest" in an entity, the assets of that plan include both
that equity interest and an undivided interest in each of the underlying assets
of the entity, unless an exception applies. The plan asset regulations contain
an exception from such plan asset rules if the security acquired by the plan is
a "publicly offered security." A "publicly offered security" is defined as a
security that is (i) freely transferable, (ii) part of a class of securities
that is owned by 100 or more investors independent of the issuer and of one
another and (iii) part of a class of securities registered under Section 12(b)
or 12(g) of the Securities Exchange Act of 1934. It is anticipated that the
class A-1 certificates will meet the criteria of the "publicly offered
securities" exception and therefore plans can generally purchase the class A-1
certificates. There are no restrictions imposed on the transfer of class A-1
certificates; the class A-1 certificates are registered under Section 12(b) of
the Securities Exchange Act of 1934; and the underwriters expect (although no
assurance can be given) that the class A-1 certificates will be held by at least
100 beneficial owners at the conclusion of the offering. If the assets included
in the trust are deemed to be plan assets, then any party exercising management
or

S- 42

ERISA CONSIDERATIONS
- --------------------------------------------------------------------------------

discretionary control regarding those assets, such as the trustee, or affiliates
of any of these parties, may be deemed to be a fiduciary with respect to the
investing plan and subject to the fiduciary responsibility provisions of ERISA.
If the assets included in the trust are plan assets, then the operation of the
trust may involve prohibited transactions under ERISA or the Internal Revenue
Code. If you are the fiduciary of a plan, you should consult your counsel before
purchasing any certificates.

PROHIBITED TRANSACTION EXEMPTIONS

In addition, regardless of whether the AOL Time Warner debentures of the trust
are plan assets, the acquisition or holding of certificates by or on behalf of a
plan could give rise to a prohibited transaction if the depositor, the
underwriters, the trustee or one of their affiliates is or becomes a party in
interest or disqualified person with respect to an investing plan. Plans
maintained or contributed to by the depositor, underwriters, trustee, and the
trustee of the AOL Time Warner debentures, or any of their affiliates, should
not acquire or hold any certificate.

If you are a plan fiduciary, then, in connection with your decision whether to
purchase any of the class A-1 certificates on behalf of a plan, you should
consider the availability of one of the following prohibited transaction class
exemptions issued by the Department of Labor:

- - Prohibited Transaction Class Exemption 75-1, which exempts particular
  transactions involving plans and broker-dealers, reporting dealers and banks;

- - Prohibited Transaction Class Exemption 90-1, which exempts particular
  transactions between insurance company separate accounts and parties in
  interest or disqualified persons;

- - Prohibited Transaction Class Exemption 91-38, which exempts particular
  transactions between bank collective investment funds and parties in interest
  or disqualified persons;

- - Prohibited Transaction Class Exemption 84-14, which exempts particular
  transactions effected on behalf of a plan by a "qualified professional asset
  manager;"

- - Prohibited Transaction Class Exemption 95-60, which exempts particular
  transactions between insurance company general accounts and parties in
  interest or disqualified persons; and

- - Prohibited Transaction Class Exemption 96-23, which exempts particular
  transactions effected on behalf of a plan by an "in-house asset manager."

We cannot provide any assurance that any of these class exemptions will apply
with respect to any particular investment by or on behalf of a plan in class A-1
certificates. Furthermore, even if any of them were deemed to apply, that
particular class exemption may not apply to all transactions that could occur in
connection with the investment.

In any event, a fiduciary or other person investing plan assets of any plan
should not purchase any certificate if the depositor, the underwriters, the
trustee, or the AOL Time Warner debentures trustee, or any of their affiliates,
either (a) has investment discretion with respect to the investment of such
assets or (b) has authority or responsibility to give or regularly gives
investment advice with respect to such assets, for a fee, pursuant to an
agreement or understanding that such advice will serve as a primary basis for
investment decisions with respect to such assets and that such advice will be
based on the particular investment needs of such plan. A party that is described
in clause (a) or (b) of the preceding sentence is a fiduciary under ERISA with
respect to the plan and any such purchase might result in a non-exempt
prohibited transaction under ERISA or section 4975 of the Internal Revenue Code.

By acquiring and holding a class A-1 certificate, a plan will be deemed to have
represented and warranted to the depositor, the trustee, and the underwriters
that the acquisition and holding of a class A-1 certificate does not involve a
non-exempt prohibited transaction with respect to the plan.

                                                                           S- 43

ERISA CONSIDERATIONS
- --------------------------------------------------------------------------------

INSURANCE COMPANY GENERAL ACCOUNTS

Section 401(c) of ERISA provides that the fiduciary and prohibited transaction
provisions of ERISA and the Internal Revenue Code do not apply to transactions
involving an insurance company general account where the assets of the general
account are not plan assets. A Department of Labor regulation issued under
section 401(c) of ERISA provides guidance for determining, in cases where
insurance policies supported by an insurer's general account are issued to or
for the benefit of a plan on or before December 31, 1998, which general account
assets are plan assets. That regulation generally provides that, if the
specified requirements are satisfied with respect to insurance policies issued
on or before December 31, 1998, the assets of an insurance company general
account will not be plan assets.

Any assets of an insurance company general account which support insurance
policies issued to a plan after December 31, 1998, or issued to a plan on or
before December 31, 1998 for which the insurance company does not comply with
the requirements set forth in the Department of Labor regulation under section
401(c) of ERISA, may be treated as plan assets. In addition, because section
401(c) of ERISA and the regulation issued under section 401(c) of ERISA do not
relate to insurance company separate accounts, separate account assets are still
treated as plan assets, invested in the separate account. If you are an
insurance company contemplating the investment of general account assets in
offered certificates, you should consult your legal counsel as to the
applicability of section 401(c) of ERISA.

CONSULTATION WITH COUNSEL

If you are a fiduciary for a plan and you intend to purchase class A-1
certificates on behalf of or with assets of that plan, you should consider your
general fiduciary obligations under ERISA and consult with your legal counsel as
to the potential applicability of ERISA and the Internal Revenue Code to that
investment and the availability of any prohibited transaction exemption in
connection with that investment.

Supplemental Plan of Distribution

Subject to the terms and conditions set forth in the underwriting agreement,
dated June 14, 2002 (the "underwriting agreement"), the depositor has agreed to
sell and each of UBS Warburg LLC, an affiliate of the depositor, and RBC Dain
Rauscher Inc. (the "underwriters"), has severally agreed to purchase, the
aggregate certificate principal balance of class A-1 certificates set forth
opposite its name below.

                                                              AGGREGATE CERTIFICATE
                                                               PRINCIPAL BALANCE OF
UNDERWRITERS                                                  CLASS A-1 CERTIFICATES
- ------------                                                  ----------------------
                                                           
UBS Warburg LLC.............................................  $          42,500,000
RBC Dain Rauscher Inc. .....................................              7,500,000
                                                              ---------------------
Total.......................................................  $          50,000,000
</Table>

The underwriters will purchase the class A-1 certificates from the depositor at
a price equal to $24.2125 per class A-1 certificate. To facilitate the initial
issuance of the call options on the class A-1 certificates, UBS Warburg LLC will
purchase all the class A-1 certificates from the depositor, and immediately
resell the aggregate certificate principal balance of class A-1 certificates set
forth opposite the name of RBC Dain Rauscher in the table above, subject to the
call options, to RBC Dain Rauscher at the same price.

The underwriters have agreed, subject to the terms and conditions set forth in
the underwriting agreement, to purchase all the class A-1 certificates if any of
the class A-1 certificates are purchased.

The depositor has been advised by the underwriters that they propose to offer
the certificates from time to time in negotiated transactions or otherwise at a
fixed price of $25.00. The underwriters may effect these transactions by selling
certificates to or through dealers and the dealers may receive compensation in
the form of underwriting discounts, concessions or commissions from the
underwriters and any purchasers of certificates for whom they may act as agent.
The underwriters and any dealers that participate with the underwriters in the
distribution of certificates may also 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.

The depositor has applied to list the class A-1 certificates on the New York
Stock Exchange. If the application is approved, trading of the class A-1
certificates on the New York Stock Exchange is expected to commence within a
30-day period after the initial delivery of the certificates.

The underwriting agreement provides that the depositor will indemnify the
underwriters against specified liabilities, including liabilities under the
Securities Act, or will contribute to any payments the underwriters may be
required to make in respect of such liabilities. In the future, UBS Warburg LLC,
or one or more of its affiliates may repurchase and resell the offered
certificates in secondary market transactions, with resales being made at prices
related to prevailing market prices at the time of resale or at negotiated
prices. However, neither UBS Warburg LLC nor any other affiliate of the
depositor is obligated to make a secondary market in the certificates, or to
continue secondary market activities once started. No assurance can be given as
to the liquidity or trading market for the certificates. For more information
about the plan of distribution, see "Plan of Distribution" in the attached
prospectus.

Ratings

It is a condition to the issuance of the class A-1 certificates that the class
A-1 certificates be rated not lower than Baa1 by Moody's and BBB+ by Standard &
Poor's. The ratings address the likelihood that the holders of the class A-1
certificates will receive payments of principal equal to the certificate

                                                                           S- 45

RATINGS
- --------------------------------------------------------------------------------

principal balance and payments of interest at the pass-through rate applicable
to the class A-1 certificates, and are based primarily on the credit quality of
the AOL Time Warner debentures, as well as on the relative priorities of each
class of the certificates with respect to collections and losses with respect to
the trust assets. The ratings on the certificates do not, however, constitute a
statement regarding the occurrence or frequency of redemptions or prepayments
on, or extensions of the maturity of, the trust assets, the probability that
call options will be exercised, or the corresponding effect of those events on
the 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 any other
security rating. We cannot assure you that the rating will not be lowered or
withdrawn entirely by the rating agency in the future, which may adversely
affect the value of your certificates.

The depositor has not requested a rating on the certificates by any rating
agency other than Moody's and Standard & Poor's. 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 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 Moody's and Standard & Poor's.

Legal Opinions

The validity of the certificates and their federal income tax status have been
passed upon for the depositor and the trust by Sidley Austin Brown & Wood LLP,
New York, New York.
