          THIS SUPPLEMENT, dated as of March 10, 2004 (this "Supplement"), to
the Series Supplement, dated as of February 25, 2004 (the "Series Supplement")
between Lehman ABS Corporation, as depositor (the "Depositor") and U.S. Bank

Depositor, the "Parties").


                              W I T N E S S E T H:
                              - - - - - - - - - -

          WHEREAS, the Parties entered into the Series Supplement for
the purpose of setting forth, among other things, certain supplemental
information with respect to the issuance of certificates initially designated
Corporate Backed Trust Certificates, Goldman Sachs Capital I Securities-Backed
Series 2004-4.


          NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, the Parties hereby agree as follows:


          1. All capitalized terms not otherwise defined herein shall have the
meanings ascribed to them in the Series Supplement.

          2. Pursuant to Section 3(d) of the Series Supplement, the Depositor
hereby sells to the Trust an additional $20,000,000 of Underlying Securities
and the Trust hereby issues an additional 800,000 Class A-1 Certificates with
an initial aggregate Certificate Principal Balance of $20,000,000 and
additional Class A-2 Certificates with an aggregate Initial Amortizing Notional
Balance of $860,000 (the "Additional Certificates"). After giving effect to the
issuance of the Additional Certificates, the Trust will have issued in the
aggregate (i) 4,200,000 Class A-1 Certificates with an aggregate initial
Certificate Principal Balance of $105,000,000 and (ii) Class A-2 Certificates
with an aggregate Initial Amortizing Notional Balance of $4,516,000. The
Additional Certificates shall have an original issue date of even date
herewith. The Trust is also issuing call warrants with respect to the
Additional Certificates (the "Additional Call Warrants"). The Class A-2
Amortization Schedule is hereby revised and amended in accordance with Section
3(d) of the Series Supplement, and is attached hereto, as revised and amended,
as Schedule I. The descriptions of the Underlying Securities, the Certificates
and the Call Warrants in the Series Supplement, including the Schedules and
Exhibits thereto, shall be deemed to be amended mutatis mutandis.

          3. If a Warrant Holder exercises all of the Class A-1 Call Warrants
and Class A-2 Call Warrants held by such Warrant Holder and exchanges the
related Called Certificates for Underlying Securities pursuant to Section 7(a)
of the Series Supplement, then (i) the Trustee shall determine that Class A-1
Certificates and Class A-2 Certificates representing a like

percentage of all outstanding Class A-1 Certificates and Class A-2 Certificates
are surrendered if such Called Certificates represent the same percentage of
their respective classes to 1/100th of a percent (not rounded), and (ii) the
Trustee shall determine that Underlying Securities distributed in exchange for
such Called Certificates represent the same percentage of Underlying Securities
as such Called Certificates represent of all outstanding Certificates if the
percentage that the Called Class A-1 Certificates represent of all Class A-1
Certificates is the same percentage that the distributed Underlying Securities
represent of all Underlying Securities. By way of example, (i) 800,000 Called
Class A-1 Certificates (19.0476% of all Class A-1 Certificates) and 34,407
Called Class A-2 Certificates (19.0473% of all Class A-2 Certificates) shall be
deemed to represent the same percentage, and (ii) such 800,000 Called Class A-1
Certificates and 34,407 Called Class A-2 Certificates shall be exchanged for
$20,000,000 by principal balance of Underlying Securities (19.0476% of all
Underlying Securities).

          4. Effect of Supplement. Except as supplemented hereby, the Series
Supplement is ratified and confirmed and continues in full force and effect.

          5. Counterparts. This Supplement may be executed in any number of
counterparts, each of which shall be deemed to be an original, and all such
counterparts shall constitute but one and the same instrument.

          6. Governing Law. THIS SUPPLEMENT AND THE TRANSACTIONS DESCRIBED
HEREIN SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE
STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND PERFORMED WITHIN THE STATE
OF NEW YORK, WITHOUT GIVING EFFECT TO THE CHOICE OF LAWS PROVISIONS THEREOF
OTHER THAN SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW.

provided for convenience only. They form no part of this Amendment or the
Series Supplement and shall not affect the construction or interpretation of
