Debenture-Backed Series 2001-32 Trust." The Certificates evidencing certain


                                       7
<PAGE>

undivided ownership interests therein shall be known as "Corporate Backed Trust
Certificates, Liberty Media Debenture-Backed Series 2001-32." The Certificates
shall consist of the Class A-1 Certificates and Class A-2 Certificates
(together, the "Certificates"). The Trust is also issuing call warrants with
respect to the Certificates ("Call Warrants").

         (a) The Certificates shall be held through the Depository in book-entry
form and shall be substantially in the forms attached hereto as Exhibits A-1 and
A-2. The Class A-1 Certificates shall be issued in denominations of $25. The
Class A-2 Certificates shall be issued in minimum denominations of $1,000,000
and in integral multiples of $1 in excess thereof. Except as provided in the
Standard Terms and in paragraph (c) of this Section, the Trust shall not issue
additional Certificates or incur any indebtedness.

         (b) The Class A-1 Certificates have an initial aggregate certificate
principal amount ("Certificate Principal Amount") of $120,685,700 and the Class
A-2 Certificates have an initial aggregate Certificate Principal Amount of
$7,314,300. The holders of the Class A-1 Certificates will be entitled to
receive on each Distribution Date the interest, if any, received on the
Underlying Securities to the extent necessary to pay interest at a rate of 8.75%
per annum on the outstanding Certificate Principal Amount of the Class A-1
Certificates. The Class A-2 Certificates shall not bear interest. On February 1,
2002, the Trustee will pay to the Depositor the amount of interest accrued and
paid on the Underlying Securities from August 1, 2001, to but not including the
Closing Date. If Available Funds are insufficient to pay such amount, the
Trustee will pay the Depositor its pro rata share, based on the ratio the amount
owed to the Depositor bears to all amounts owed on the Class A-1 Certificates in
respect of accrued interest, of any proceeds from the recovery on the Underlying
Securities.

         (c) The Depositor may sell to the Trustee additional Underlying
Securities on any date hereafter upon at least 3 Business Days (or such lesser
period as may be agreed by the parties hereto) notice to the Trustee and upon
(i) satisfaction of the Rating Agency Condition and (ii) delivery of an Opinion
of Counsel to the effect that the sale of such additional Underlying Securities
will not materially increase the likelihood that the Trust would fail to qualify
as a grantor trust under the Code. Upon such sale to the Trustee, the Trustee
shall deposit such additional Underlying Securities in the Certificate Account,
and shall authenticate and deliver to the Depositor, on its order, Class A-1
Certificates and Class A-2 Certificates in the same proportion as the original
Class A-1 Certificates and Class A-2 Certificates bear to the initial Underlying
Securities, as well as the Call Warrants related thereto. Any such additional
Class A-1 Certificates and Class A-2 Certificates authenticated and delivered
shall have the same terms and rank pari passu with the original Class A-1
Certificates and Class A-2 Certificates, respectively, issued in accordance with
this Series Supplement.

         (d) As a condition precedent for transferring the Call Warrants, the
prospective transferee shall be required to deliver to the Trustee and the
Depositor, an executed copy of the Investment Letter (set forth as Exhibit D-1
hereto).

as a condition precedent for transferring the Class A-2 Certificates, the
prospective transferee and the prospective transferor shall be required to
deliver to the Trustee and the Depositor an executed copy of the Investment
Letter (set forth as Exhibit D-2 hereto). No Class A-2 Certificate may be
resold, assigned or transferred (including by pledge or hypothecation) unless

Act") and any applicable state securities laws, (ii) pursuant to Rule 144A
promulgated under the Securities Act ("Rule 144A"), (iii) pursuant to Regulation
D under the Securities Act ("Regulation D") or (iv) pursuant to another

shall have acknowledged, represented and agreed as follows:

         1. The purchaser (A)(i) is a qualified institutional investor (as such
term is defined in the Securities Act) (a "QIB"), (ii) is aware that the sale to

Certificates for its own account or for the account of a QIB or (B)(i) is an

D and (iii) is acquiring such Class A-2 Certificates for its own account or for
the account of an Accredited Investor.

         2. The purchaser understands that the Class A-2 Certificates are being

within the meaning of the Securities Act, and that the Class A-2 Certificates
have not been and will not be registered under the Securities Act.

         3. The purchaser agrees that (A) if in the future it decides to
reoffer, resell, pledge or otherwise transfer the Class A-2 Certificates, such
Class A-2 Certificates may be reoffered, resold, pledged or otherwise
transferred only (i) to the Trust, (ii) inside the United States to a QIB in
accordance with Rule 144A, (iii) inside the United States to an Accredited
Investor pursuant to Regulation D, (iv) pursuant to an exemption from
registration under the Securities Act provided by Rule 144 thereunder (if

         Section 4. Trust Certificates. The Trustee hereby acknowledges receipt,
on or prior to the Closing Date, of:

                  (i) the Underlying Securities set forth on the Underlying
Securities Schedule; and

                  (ii) all documents required to be delivered to the Trustee
pursuant to Section 2.01 of the Standard Terms.

                  Section 5. Distributions. (a) On each applicable Distribution
Date, the Trustee shall apply Available Funds in the Certificate Account as
follows, in the following order of priority:

         (i) the Trustee will pay the interest portion of Available Funds with
respect to the Underlying Securities (subject to Section 5(b) below):

                  (a) first, to the Trustee, as reimbursement for any
Extraordinary Trust Expenses incurred by the Trustee with respect to the
Underlying Securities in accordance with Section 6(b) below and approved by 100%
of the Certificateholders;

                  (b) second, to the holders of the Class A-1 Certificates,
interest at the rate of 8.75% per annum on the principal amount of the Class A-1
Certificates; and

                  (c) third, to the Depositor, any remainder.

         (ii) the Trustee will pay the principal portion of Available Funds with
respect to the Underlying Securities:

                  (a) first, to the Trustee, as reimbursement for any remaining
Extraordinary Trust Expenses incurred by the Trustee with respect to the
Underlying Securities in accordance with Section 6(b) below and approved by 100%
of the Certificateholders; and

                  (b) second, to the holders of the Class A-1 Certificates and
Class A-2 Certificates, the remaining principal portion of Available Funds pro
rata in the proportion that the outstanding principal amount of the Class A-1
Certificates bears to the outstanding principal amount of the Class A-2
Certificates.

         (b) Notwithstanding any other provision hereof, if the Underlying
Securities are prepaid or liquidated in whole or in part for any reason other
than due to the failure of the Underlying Securities Issuer to file periodic
reports as required by the Exchange Act, the Trustee shall apply Available Funds
in the manner described in Section 5(g) in the following order of priority:

                  (i) first, to the Trustee, as reimbursement for any
Extraordinary Trust Expenses incurred by the Trustee in accordance with Section
6(b) below and approved by 100% of the Certificateholders;

                  (ii) second, to the holders of the Class A-1 Certificates, an
amount equal to any accrued and unpaid interest thereon; and

                  (iii) third, to the holders of the Class A-1 Certificates and
Class A-2 Certificates, pro rata in the proportion that the outstanding
principal amount of the Class A-1 Certificates bears to the outstanding
principal amount of the Class A-2 Certificates.

         (c) Notwithstanding the foregoing, if the Underlying Securities are
prepaid or liquidated in whole or in part due to the failure to file periodic
reports, the Trustee shall apply Available Funds in the following order of


                                       11
<PAGE>

priority: (i) to the Trustee, reimbursement for any remaining Extraordinary
Trust Expenses and (ii) to the holders of the Class A-1 Certificates and the
holders of the Class A-2 Certificates in accordance with the ratio of the Class
A-1 Allocation to the Class A-2 Allocation.

         (d) Unless otherwise instructed by holders of Certificates representing
a majority of the Voting Rights within thirty (30) days after the Trustee gives
notice pursuant to Section 8 hereof, the Trustee will sell the Underlying
Securities pursuant to Section 13 hereof and deposit the Liquidation Proceeds,
if any, into the Certificate Account for distribution not later than two (2)
Business Days after the receipt of immediately available funds in accordance
with Section 5(b) hereof.

         (e) In the event that the Trustee receives non-cash property in respect
of the Underlying Securities (other than a scheduled payment on or with respect
to an interest payment date) as a result of a payment default on the Underlying
Securities (including from the sale thereof), the Trustee will promptly give
notice to the Depositary, or for any Certificates which are not then held by DTC
or any other depository, directly to the registered holders of the Certificates
then outstanding and unpaid. Such notice shall state that, not later than 30
days after the receipt of such property, the Trustee will allocate and
distribute such property to the holders of Certificates then outstanding and
unpaid, pro rata by principal amount (after deducting the costs incurred in
connection therewith). Property other than cash will be liquidated by the
Trustee, and the proceeds thereof distributed in cash, only to the extent
necessary to avoid distribution of fractional securities to Certificateholders.
In-kind distribution of such property to Certificateholders will be deemed to
reduce the principal amount of Certificates on a dollar-for-dollar basis.

         (f) Subject to Section 9(f) hereof, to the extent Available Funds are
insufficient to make any required distributions due to any class of Certificates
on any Distribution Date, any shortfall will be carried over and will be
distributed on the next Distribution Date (or date referred to in Section 5(g)
hereof) on which sufficient funds are available to pay such shortfall.

         (g) If a payment with respect to the Underlying Securities is made to
the Trustee after the Distribution Date on which such payment was scheduled to
be distributed in respect of the Certificates, then the Trustee will distribute
any such amounts received on the next occurring Business Day (a "Special
Distribution Date") as if the funds had constituted Available Funds on the
Distribution Date immediately preceding such Special Distribution Date;
provided, however, that the Record Date for such Special Distribution Date shall
be five Business Days prior to the day on which the related payment was received
from the Underlying Securities Trustee.

         (h) Notwithstanding Section 3.12 of the Standard Terms, if the
Underlying Securities Issuer ceases to file periodic reports as required under
the Exchange Act, the Depositor shall within a reasonable period of time
instruct the Trustee to (i) distribute the Underlying Securities in-kind to the


                                       12
<PAGE>

Certificateholders or (ii) sell the Underlying Securities and distribute the
proceeds of such sale to the Certificateholders in accordance with Section 5(c)
hereof; provided, however, that the Depositor shall not instruct the Trustee
pursuant to this clause unless the Underlying Securities Issuer has either (x)
stated in writing that it intends permanently to cease filing reports required
under the Exchange Act or (y) failed to file any required reports for one full
calendar year.

         Section 6. Trustee's Fees. (a) As compensation for its services
hereunder, the Trustee shall be entitled to the Trustee Fee. The Trustee Fee
shall be paid by the Depositor and not from Trust Property. The Trustee shall
bear all Ordinary Expenses. Failure by the Depositor to pay such amount shall
not entitle the Trustee to any payment or reimbursement from the Trust, nor
shall such failure release the Trustee from the duties it is required to perform
under the Trust Agreement.

         (b) Extraordinary Expenses shall not be paid out of the Trust Property
unless all of the Certificateholders then outstanding have directed the Trustee
to incur such Extraordinary Expenses. The Trustee may incur other Extraordinary
Expenses if any lesser percentage of the Certificateholders requesting such
action pursuant hereto reimburse the Trustee for the cost thereof from their own
funds in advance. If Extraordinary Expenses are not approved unanimously as set
forth in the first sentence of this Section 6(b), such Extraordinary Expenses
shall not be an obligation of the Trust, and the Trustee shall not file any
claim against the Trust therefor notwithstanding failure of certificateholders
to reimburse the Trustee.

         Section 7. Optional Exchange; Optional Call

         (a) (i) On any Distribution Date, any holder of Class A-1 Certificates
and Class A-2 Certificates and the related Call Warrants, if Call Warrants
related to such Certificates are outstanding, may exchange such Certificates
and, if applicable, the related Call Warrants, for a distribution of Underlying
Securities representing the same percentage of the Underlying Securities as such
Certificates represent of all outstanding Certificates.

                  (ii)     The following conditions shall apply to any Optional
                           Exchange.

                           (a) A notice specifying the number of Certificates
                           being surrendered and the Optional Exchange Date
                           shall be delivered to the Trustee no less than 5 days
                           (or such shorter period acceptable to the Trustee)
                           but not more than 30 days before the Optional
                           Exchange Date.

                           (b) Certificates and, if applicable, the Call
                           Warrants, shall be surrendered to the Trustee no
                           later than 10:00 a.m. (New York City time) on the
                           Optional Exchange Date.

<PAGE>

                           (c) Class A-1 Certificates and Class A-2 Certificates
                           representing a like percentage of all Class A-1
                           Certificates and Class A-2 Certificates shall be
                           surrendered.

                           (d) The Trustee shall have received an opinion of
                           counsel stating that the Optional Exchange would not
                           affect the characterization of the Trust as a
                           "grantor trust" for federal income tax purposes.

                           (e) Except in connection with the exchange of
                           Certificates acquired pursuant to Section 7(b), (1)
                           the Trustee shall have received a certification from
                           the Certificateholder that any Certificates being
                           surrendered have been held for at least six months,
                           and (2) the Certificates being surrendered may
                           represent no more than 5% (or 25% in the case of
                           Certificates acquired by the Underwriter but never
                           distributed to investors) of the then outstanding
                           Certificates.

                           (f) The Trustee shall not be obligated to determine
                           whether an Optional Exchange complies with the
                           applicable provisions for exemption under Rule 3a-7
                           of the Investment Company Act of 1940, as amended, or
                           the rules or regulations promulgated thereunder.

                           (g) The provisions of Section 4.07 of the Standard
                           Terms shall not apply to an Optional Exchange
                           pursuant to this Section 7(a). This Section 7(a)
                           shall not provide any person with a lien against, an
                           interest in or a right to specific performance with
                           respect to the Underlying Securities.

         (b) (i) Concurrently with the execution of this Series Supplement, the
Trustee, on behalf of the Trust, shall execute the Warrant Agent Agreement and
the Call Warrants, dated as of the date hereof and substantially in the forms of
Exhibit B-1 and Exhibit B-2 hereto, initially evidencing all of the Call
Warrants. The Trustee shall perform the Trust's obligations under the Warrant
Agent Agreement and the Call Warrants in accordance with their respective terms.
On any Call Date, each class of Certificates may be called at the applicable
Call Price, in whole or in part, by the Warrant Holder, upon payment of such
Call Price on or prior to such Call Date. In the case of a call in part, the
Class A-1 Certificates and Class A-2 Certificates must be called in the same
proportion that each certificate bears to the outstanding principal amount of
the Certificates. In addition to the conditions described in this Section 7(b)
relating to any Optional Call, the conditions set forth in Section 1.1 of the
Warrant Agent Agreement shall also apply.

                  (ii) The Warrant Holder may provide notice to the Trustee (a
"Call Notice") no less than 5 Business Days prior to any Call Date, that it is
exercising its Call Warrants with respect to the Certificates on such Call Date.


                                       14
<PAGE>

Upon request of the Trustee, the Warrant Holder shall deliver the opinion
specified in Section 7(a)(ii)(d) above as a condition to any Optional Call.

                  (iii) Upon receipt of a Call Notice, the Trustee shall provide
a conditional call notice to the Depository not less than 3 Business Days prior
to the applicable Call Date.

                  (iv) As a condition to any Optional Call, an opinion of
counsel to the Warrant Holder shall be delivered to the Rating Agencies, in form
satisfactory to the Rating Agencies, indicating that payment of the Call Price
shall not be recoverable as a preferential transfer or fraudulent conveyance
under the United States Bankruptcy Code. Such opinion may contain customary
assumptions and qualifications. In addition, the Warrant Holder shall provide a
certificate of solvency to the Trustee.

                  (v) Deliveries of the Underlying Securities to the Warrant
Holder (the "Purchaser") will only be made against payment by the Purchaser of
the Call Price in immediately available funds. Such payment must occur no later
than 10:00 a.m. New York City time on the Call Date. In the event that the
Purchaser fails to make such payment by such time (a "Purchase Default"), the
sale shall be voided and the Optional Call will be deemed not to be effective
with respect to such Distribution Date, and the Certificates and the Call
Warrants shall continue to remain outstanding. Subject to receipt of the Call
Price as aforesaid, the Trustee shall pay the Call Price to the
Certificateholders on the Call Date in accordance with the definition of "Call
Price". The Call Price in respect of partial calls shall be allocated to the
Certificateholders within each class pro rata to the extent of their
entitlements thereto.

                  (vi) The Trustee shall not consent to any amendment or
modification of this Agreement (including the Standard Terms) which would alter
the timing or amount of any payment of the Call Price without the prior written
consent of 100% of the Warrant Holders.

                  (vii) The Trustee shall not be obligated to determine whether
an Optional Call complies with the applicable provisions for exemption under
Rule 3a-7 of the Investment Company Act of 1940, as amended, or the rules or
regulations promulgated thereunder.

                  (viii) This Section 7 shall not provide the Warrant Holder
with a lien against, an interest in or a right to specific performance with
respect to the Underlying Securities.

                  (ix) The Warrant Holder shall initially be the Depositor.

         Section 8. Notices of Events of Default.

         As promptly as practicable after, and in any event within 30 days
after, the occurrence of any Event of Default actually known to the Trustee, the
Trustee shall give notice of such Event of Default to the Depository, or, if any


                                       15
<PAGE>

Certificates are not then held by DTC or any other depository, directly to the
registered holders of such Certificates. However, except in the case of an Event
of Default relating to the payment of principal of or interest on any of the
Underlying Securities, the Trustee will be protected in withholding such notice
if in good faith it determines that the withholding of such notice is in the
interest of the Certificateholders.

         Section 9. Miscellaneous.

         (a) The provisions of Section 4.04, Advances, of the Standard Terms
shall not apply to the Liberty Media Debenture-Backed Series 2001-32
Certificates.

         (b) The provisions of Section 4.07, Optional Exchange, of the Standard
Terms shall not apply to the Liberty Media Debenture-Backed Series 2001-32
Certificates.

         (c) The Trustee shall simultaneously forward reports to
Certificateholders pursuant to Section 4.03 of the Standard Terms and to the New
York Stock Exchange.

         (d) Except as expressly provided herein, the Certificateholders shall
not be entitled to terminate the Trust or cause the sale or other disposition of
the Underlying Securities.

         (e) The provisions of Section 3.07(d) of the Standard Terms shall not
apply to the Liberty Media Debenture-Backed Series 2001-32 Certificates.

         (f) If the Trustee has not received payment with respect to a
Collection Period on the Underlying Securities on or prior to the related
Distribution Date, such distribution will be made promptly upon receipt of such
payment. No additional amounts shall accrue on the Certificates or be owed to
Certificateholders as a result of such delay; provided, however, that any
additional interest owed and paid by the Underlying Securities Issuer as a
result of such delay shall be paid to the Class A-1 Certificateholders, pro rata
in proportion to their respective entitlements to interest.

         (g) The outstanding principal balance of the Certificates shall not be
reduced by the amount of any Realized Losses (as defined in the Standard Terms).

         (h) The Trust may not engage in any business or activities other than
in connection with, or relating to, the holding, protecting and preserving of
the Trust Property and the issuance of the Certificates, and other than those
required or authorized by the Trust Agreement or incidental and necessary to
accomplish such activities. The Trust may not issue or sell any certificates or
other obligations other than the Certificates or otherwise incur, assume or
guarantee any indebtedness for money borrowed.

         (i) Notwithstanding anything in the Trust Agreement to the contrary,
the Trustee may be removed upon 60 days prior written notice delivered by the
holders of the Certificates representing the Required Percentage-Removal.



                                       16
<PAGE>

         (j) In the event that the Internal Revenue Service challenges the
characterization of the Trust as a grantor trust, the Trustee shall then file
such forms as the Depositor may specify to establish the Trust's election
pursuant to Section 761 of the Code to exclude the Trust from the application of
Subchapter K of the Code and is hereby empowered to execute such forms on behalf
of the Certificateholders.

         (k) Notwithstanding anything in the Standard Terms to the contrary, the
Trustee, upon written direction by the Depositor, will execute the Certificates.

         (l) In relation to Section 7.01(f) of the Standard Terms, any periodic
reports filed by the Trustee pursuant to the Securities and Exchange Act of
1934, as amended, and the rules and regulations promulgated thereunder, in
accordance with the customary practices of the Depositor, need not contain any
independent reports.

         (m) Notwithstanding anything in the Trust Agreement to the contrary,
the Trustee will have no recourse to the Underlying Securities.

         (n) The Trust will not merge or consolidate with any other entity
without confirmation from each Rating Agency that such merger or consolidation
will not result in the qualification, reduction or withdrawal of its
then-current rating on the Certificates.

         (o) Notices. All directions, demands and notices hereunder or under the
Standard Terms shall be in writing and shall be delivered as set forth below
(unless written notice is otherwise provided to the Trustee).

         Section 13. Sale of Underlying Securities. In the event of a sale of
the Underlying Securities pursuant to Section 5(c) hereof or pursuant to the
instructions of the Warrant Agent under Section 1.2 of the Warrant Agent
Agreement, the Trustee shall solicit bids for the sale of the Underlying
Securities with settlement thereof on or before the third Business Day after
such sale from three leading dealers in the relevant market. Any of the
following dealers (or their successors) shall be deemed to qualify as leading
dealers: (1) Credit Suisse First Boston Corporation, (2) Goldman, Sachs & Co.,
(3) Merrill Lynch, Pierce, Fenner & Smith Incorporated, (4) UBS Warburg LLC, (5)
Salomon Smith Barney Inc., and (6) except in the case of a sale related to the
exercise of Call Warrants by the Depositor or any Affiliate thereof, Lehman
Brothers Inc. The Trustee shall not be responsible for the failure to obtain a
bid so long as it has made reasonable efforts to obtain bids. If a bid for the
sale of the Underlying Securities has been accepted by the Trustee but the sale
has failed to settle on the proposed settlement date, the Trustee shall request
new bids from such leading dealers. In the event of an Optional Exchange, the
Trustee shall only deliver the Underlying Securities to the purchaser of such
Underlying Securities or sell the Underlying Securities pursuant to this Section
13, as the case may be, against payment in same day funds deposited into the
Certificate Account.

         Section 14. Amendments. Notwithstanding anything in the Trust Agreement
to the contrary, in addition to the other restrictions on modification and
amendment contained therein, the Trustee shall not enter into any amendment or
modification of the Trust Agreement which would adversely affect in any material
respect the interests of the holders of any class of Certificates without the
consent of the holders of 100% of such class of Certificates; provided, however,
that no such amendment or modification will be permitted which would alter the
status of the Trust as a grantor trust for federal income tax purposes. Further,
no amendment shall be permitted which would adversely affect in any material
respect the interests of any Class of Certificateholders without confirmation by
each Rating Agency that such amendment will not result in a downgrading or
withdrawal of its rating of such Class of Certificates.

         Section 15. Voting of Underlying Securities, Modification of Indenture.
The Trustee, as holder of the Underlying Securities, has the right to vote and
give consents and waivers in respect of the Underlying Securities as permitted
by the Depository and except as otherwise limited by the Trust Agreement. In the
event that the Trustee receives a request from the Depository, the Underlying
Securities Trustee or the Underlying Securities Issuer for its consent to any
amendment, modification or waiver of the Underlying Securities, the Indenture or
any other document thereunder or relating thereto, or receives any other
solicitation for any action with respect to the Underlying Securities, the
Trustee shall mail a notice of such proposed amendment, modification, waiver or
solicitation to each Certificateholder of record as of such date. The Trustee
shall request instructions from the Certificateholders as to whether or not to
consent to or vote to accept such amendment, modification, waiver or
solicitation. The Trustee shall consent or vote, or refrain from consenting or
voting, in the same proportion (based on the relative outstanding principal
balances of the Certificates) as the Certificates of the Trust were actually


                                       19
<PAGE>

voted or not voted by the Certificateholders thereof as of a date determined by
the Trustee prior to the date on which such consent or vote is required,
provided, however, that, notwithstanding anything in the Trust Agreement to the
contrary, the Trustee shall at no time vote on or consent to any matter (i)
unless such vote or consent would not (based on an opinion of counsel) alter the
status of the Trust as a grantor trust for federal income tax purposes or result
in the imposition of tax upon the Certificateholders, (ii) which would alter the
timing or amount of any payment on the Underlying Securities, including, without
limitation, any demand to accelerate the Underlying Securities, except in the
event of a default under the Underlying Securities or an event which with the
passage of time would become an event of default under the Underlying Securities
and with the unanimous consent of all outstanding Class A-1 Certificateholders
and Class A-2 Certificateholders, or (iii) which would result in the exchange or
substitution of any of the outstanding Underlying Securities pursuant to a plan
for the refunding or refinancing of such Underlying Securities except in the
event of a default under the Indenture and only with the consent of
Certificateholders representing 100% of the Class A-1 Certificates and 100% of
the Class A-2 Certificates. The Trustee shall have no liability for any failure
to act resulting from Certificateholders' late return of, or failure to return,
directions requested by the Trustee from the Certificateholders.

         In the event that an offer is made by the Underlying Securities Issuer
to issue new obligations in exchange and substitution for any of the Underlying
Securities, pursuant to a plan for the refunding or refinancing of the
outstanding Underlying Securities or any other offer is made for the Underlying
Securities, the Trustee shall notify the Class A-1 Certificateholders and Class
A-2 Certificateholders of such offer promptly. The Trustee must reject any such
offer unless the Trustee is directed by the affirmative vote of the holders of
100% of all of the Certificates to accept such offer and the Trustee has
received the tax opinion described above. If pursuant to the preceding sentence,
the Trustee accepts any such offer, the Trustee shall promptly notify the Rating
Agencies.

         If an event of default under the Indenture occurs and is continuing,
and if directed by a majority of the outstanding Class A-1 Certificateholders
and Class A-2 Certificateholders, the Trustee shall vote the Underlying
Securities in an outstanding principal amount equal to the outstanding
certificate principal amount of the Certificates in favor of directing, or take
such other action as may be appropriate to direct, the Underlying Securities
Trustee to declare the unpaid principal amount of the Underlying Securities and
any accrued and unpaid interest thereon to be due and payable.

         Section 16. UCC Representations and Warranties.

         It is the express intent of the parties hereto that the conveyance of
the Underlying Securities by the Depositor to the Trustee be, and be construed
as, a sale of the Underlying Securities by the Depositor and not a pledge of any
Underlying Securities by the Depositor to secure a debt or other obligation of
the Depositor. In the event that, notwithstanding the aforementioned intent of
the parties, any Underlying Securities are held to be property of the Depositor,
then, it is the express intent of the parties that such conveyance be deemed a
pledge of such Underlying Securities by the Depositor to the Trustee to secure a


                                       20
<PAGE>

debt or other obligation of the Depositor, pursuant to Section 10.07 of the
Standard Terms. In connection with any such grant of a security interest in the
Underlying Securities, Depositor hereby represents and warrants to Trustee as
follows:

         (i)      In the event the Underlying Securities are held to be property
                  of the Depositor, then the Trust Agreement creates a valid and
                  continuing security interest (as defined in the applicable
                  Uniform Commercial Code) in the Underlying Securities in favor
                  of the Trustee which security interest is prior to all other
                  liens, and is enforceable as such as against creditors of, and
                  purchasers from, the Depositor.

         (ii)     The Underlying Securities have been credited to a trust
                  account (the "Securities Account") of the Trustee, or its
                  authorized agent, in accordance with Section 2.01 of the
                  Standard Terms. The Trustee, as securities intermediary for
                  the Securities Account, has agreed to treat the Underlying
                  Securities as "financial assets" within the meaning of the
                  Uniform Commercial Code.

         (iii)    Immediately prior to the transfer of the Underlying Securities
                  to the Trust, Depositor owned and had good and marketable
                  title to the Underlying Securities free and clear of any lien,
                  claim or encumbrance of any Person.

         (iv)     Depositor has received all consents and approvals required by
                  the terms of the Underlying Securities to the transfer to the
                  Trustee of its interest and rights in the Underlying
                  Securities as contemplated by the Trust Agreement.

         (v)      Depositor has taken all steps necessary to cause the Trustee,
                  as securities intermediary for the Securities Account, to
                  identify on its records that the Trustee, as the trustee of
                  the Trust, is the Person having a security entitlement against
                  the securities intermediary in the Securities Account.

         (vi)     Depositor has not assigned, pledged, sold, granted a security
                  interest in or otherwise conveyed any interest in the
                  Underlying Securities (or, if any such interest has been
                  assigned, pledged or otherwise encumbered, it has been
                  released). Depositor has not authorized the filing of and is
                  not aware of any financing statements against Depositor that
                  includes a description of the Underlying Securities. Depositor
                  is not aware of any judgment or tax lien filings against
                  Depositor.

         (vii)    The Securities Account is not in the name of any Person other
                  than the Trust. Depositor has not consented to the compliance
                  by the Trustee, as securities intermediary, with entitlement
                  orders of any Person other than the Trustee, as trustee of the
                  Trust.

Certificate by virtue of the acceptance hereof assents and by which such Holder
is bound. The Trust Property consists of: (i) Underlying Securities described in
the Trust Agreement; (ii) all payments on or collections in respect of the
Underlying Securities accrued on or after August 29, 2001 together with any
proceeds thereof; and (iii) all funds from time to time deposited with the
Trustee relating to the Certificates, together with any and all income, proceeds
and payments with respect thereto; provided, however, that any income from the
investment of Trust funds in certain permitted investments ("Eligible
Investments") does not constitute Trust Property.

                     Subject to the terms and conditions of the Trust Agreement
(including the availability of funds for distributions) and until the obligation
created by the Trust Agreement shall have terminated in accordance therewith,
distributions will be made on each Distribution Date, to the Person in whose
name this Certificate is registered on the applicable Record Date, in an amount
equal to such Certificateholder's proportionate undivided beneficial ownership
interest in the amount required to be distributed to the Holders of the
Certificates on such Distribution Date. The Record Date applicable to any
Distribution Date is the close of business on the day immediately preceding such
Distribution Date (whether or not a Business Day). If a payment with respect to
the Underlying Securities is made to the Trustee after the date on which such
payment was due, then the Trustee will distribute any such amounts received on
the next occurring Business Day (a "Special Distribution Date").

                     Each Certificateholder, by its acceptance of a Certificate,
covenants and agrees that such Certificateholder will not at any time institute
against the Trust, or join in any institution against the Trust of, any
bankruptcy proceedings under any United States Federal or state bankruptcy or
similar law in connection with any obligations relating to the Certificates or

by the holder of this instrument (this "Call Warrant") at a call price equal to
the Call Price (as defined below), all subject to the terms and conditions set
forth below.

           Certain capitalized terms used in this Call Warrant are defined in
Article IV hereof; capitalized terms used but not defined herein shall have the
respective meanings set forth in the Trust Agreement; references to an "Exhibit"
are, unless otherwise specified, to one of the Exhibits attached to this Call
Warrant and references to a "Section" are, unless otherwise specified, to one of
the sections of this Call Warrant.


                                   ARTICLE I

                           Exercise of Call Warrants

           Section 1.1 Manner of Exercise. (a) This Call Warrant may be
exercised by the holder hereof (each, a "Warrant Holder"), in whole or in part,
on any Call Date, set forth in a written notice delivered to the Warrant Agent
and the Trustee at any time on or before the Business Day that is at least 5
Business Days before such Call Date, by surrender of this Call Warrant to the
Warrant Agent at its office set forth in Section 6.3 hereof no later than 10:00
a.m. (New York City time) on such Call Date; provided that such holder shall
have made payment to the Warrant Agent, by wire transfer or other immediately
available funds acceptable to the Warrant Agent, in the amount of the applicable
Call Price, in a manner such that funds are available to the Warrant Agent no
later than 10:00 a.m. (New York City time) on such Call Date, and such holder
shall thereupon be entitled to delivery of the Certificates in a Certificate
Principal Amount equal to $25 per Call Warrant (if exercised in whole); provided
further that the Warrant Holder may only exercise Call warrants if it is
simultaneously exercising Call Warrants relating to Class A-1 Certificates and
Call Warrants relating to Class A-2 Certificates which represent a like
percentage of all Class A-1 Certificates and Class A-2 Certificates,
respectively; provided further that if the Warrant Holder is the Depositor or an
Affiliate thereof, such Warrant Holder shall not be entitled to delivery of the
Certificates being called (the "Called Certificates"), and shall only be
entitled to receive the cash proceeds of the sale of the Underlying Securities
related to such Called Certificates; and provided further that the Warrant
Holder may not exercise this Call Warrant at any time when such Warrant Holder
is insolvent, and in connection therewith, such Warrant Holder shall be required
to certify that it is solvent at the time of exercise settlement, by completing
the Form of Subscription attached to this Call Warrant and delivering such
completed Form of Subscription to the Trustee on or prior to the Call Date and
deliver to the Trustee a form reasonably satisfactory to the Trustee of the
opinion and the solvency certificate required pursuant to Section 7(b)(iv) of
the Series Supplement.

           (b) The Warrant Agent shall notify the Trustee immediately upon
receipt by the Warrant Agent of a notice by the holder of this Call Warrant and
upon receipt of payment of the applicable Call Price from such holder pursuant
to clause (a) of this Section 1.1. The Warrant Agent shall transfer each payment
made by the holder hereof pursuant to clause (a) of this Section 1.1 to the
Trustee in immediately available funds, for application pursuant to the Trust




                                     B-1-2
<PAGE>

Agreement on the applicable Call Date (and, pending such transfer, shall hold
each such payment for the benefit of the holder hereof in a segregated trust
account).

           (c) A notice by the holder of a Call Warrant does not impose any
obligations on a holder of a Call Warrant in any way to pay any Call Price. If,
by 10:00 a.m. (New York City time) on the Call Date, the holder of the Call
Warrant being exercised has not paid the Call Price, then such notice shall
automatically expire and none of the holder of such Call Warrant, the Warrant
Agent and the Trustee shall have any obligations with respect to such notice by
the holder of such Call Warrant. The expiration of a notice by the holder of
this Call Warrant shall in no way affect a holder of a Call Warrant's right to
subsequently deliver a notice which satisfies the terms of the Trust Agreement.

           Section 1.2 Transfer of Certificates. As soon as practicable after
each surrender of this Call Warrant, in whole or in part on the Call Date and
upon satisfaction of all other requirements described in this Call Warrant, the
Warrant Agent shall instruct the Trustee to cause a number of the Class A-1
Certificates equal to the number of the Call Warrants being exercised hereunder
to reflect the new beneficial ownership of the Class A-1 Certificates, and, in
case such exercise is in part only, a new Call Warrant of like tenor,
representing the remaining outstanding Call Warrants of the holder, shall be
delivered by the Warrant Agent to the holder hereof.

           Section 1.3 Cancellation and Destruction of Call Warrant. All Call
Warrants surrendered to the Warrant Agent for the purpose of exercise (in whole
or in part) pursuant to Section 1.1 and actually exercised, or for the purpose
of transfer or exchange pursuant to Article III, shall be cancelled by the
Warrant Agent, and no Call Warrant shall be issued in lieu thereof. The Warrant
Agent shall destroy all cancelled Call Warrants.

           Section 1.4 No Rights as Holder of Certificates Conferred by Call
Warrants. Prior to the exercise hereof, this Call Warrant shall not entitle the
holder hereof to any of the rights of a holder of the Certificates, including,
without limitation, the right to receive the payment of any amount on or in
respect of the Certificates or to enforce any of the covenants of the Trust
Agreement.

                                   ARTICLE II

                            Restrictions on Transfer

           Section 2.1 Restrictive Legends. Except as otherwise permitted by
this Article II, each Call Warrant (including each Call Warrant issued upon the
transfer of any Call Warrant) shall be issued with a legend in substantially the
following form:

           "This Call Warrant has not been registered under the Securities Act
of 1933, as amended, and may not be transferred, sold or otherwise disposed of
except while a registration under such Act is in effect or pursuant to an



                                     B-1-3

transferred only in compliance with the conditions specified in this Call
Warrant."

           Section 2.2 Notice of Proposed Transfer. Prior to any transfer of any
Call Warrant or portion thereof, the holder hereof will give five (5) Business
Days (or such lesser period acceptable to the Warrant Agent) prior written
notice to the Warrant Agent of such holder's intention to effect such transfer.

                                  ARTICLE III

                Registration and Transfer of Call Warrants, etc.

           Section 3.1 Warrant Register; Ownership of Call Warrants. The Warrant
Agent will keep a register in which the Warrant Agent will provide for the
registration of Call Warrants and the registration of transfers of Call Warrants
representing whole numbers of Call Warrants. The Trustee and the Warrant Agent
may treat the Person in whose name any Call Warrant is registered on such
register so the owner thereof for all purposes, and the Trustee and the Warrant
Agent shall not be affected by any notice to the contrary.

           Section 3.2 Transfer and Exchange of Call Warrants. Upon surrender of
any Call Warrant for registration of transfer or for exchange to the Warrant
Agent, the Warrant Agent shall (subject to compliance with Article II) execute
and deliver, and cause the Trustee, on behalf of the Trust, to execute and
deliver, in exchange therefor, a new Call Warrant of like tenor and evidencing a
like whole number of Call Warrants, in the name of such holder or as such holder
(upon payment by such holder of any applicable transfer taxes or government
charges) may direct.

           Section 3.3 Replacement of Call Warrants Upon receipt of evidence
reasonably satisfactory to the Warrant Agent of the loss, theft, destruction or
mutilation of any Call Warrant and, in the case of any such loss, theft or
destruction of any Call Warrant, upon delivery of an indemnity bond in such
reasonable amount as the Warrant Agent may determine, or, in the case of any
such mutilation, upon the surrender of such Call Warrant for cancellation to the
Warrant Agent, the Warrant Agent shall execute and deliver, and cause the
Trustee, on behalf of the Trust, to execute and deliver, in lieu thereof, a new
Call Warrant of like tenor bearing a number not contemporaneously outstanding.

           Section 3.4 Execution and Delivery of Call Warrants by Trustee. The
Trustee, on behalf of the Trust, hereby agrees (subject to compliance with
Article II) to execute and deliver such new Call Warrants issued in accordance
with Section 1.2 or this Article III as the Warrant Agent shall request in
accordance herewith.

fail to make such appointment of a permanent successor within a period of thirty
(30) days after such removal or within sixty (60) days after notification in
writing of such resignation or incapacity by the resigning or incapacitated
Warrant Agent or by the holder of a Call Warrant, then the Warrant Agent or
registered holder of any Warrant may apply to any court of competent
jurisdiction for the appointment of such a successor. Any successor to the
Warrant Agent appointed hereunder must be rated in one on the four highest
rating categories by the Rating Agencies. Any entity which may be merged or
consolidated with or which shall otherwise succeed to substantially all of the
trust or agency business of the Warrant Agent shall be deemed to be the
successor Warrant Agent without any further action.

Warrant in the event of any default or threatened default by the Warrant Agent
in the performance of or compliance with any of the terms of this Call Warrant
are not and will not be adequate and, to the full extent permitted by law, such
terms may be specifically enforced by a decree for the specific performance of
any agreement contained herein or by an injunction against a violation of any of
the terms hereof or otherwise.

to time by the Depositor, the Trustee and the Warrant Agent without the consent
of any holder hereof, upon receipt of an opinion of counsel satisfactory to the
Warrant Agent that the provisions hereof have been satisfied and that such
amendment would not alter the status of the Trust as a grantor trust under the
Code, for any of the following purposes: (i) to cure any ambiguity or to correct
or supplement any provision herein which may be defective or inconsistent with
any other provision herein or to provide for any other terms or modify any other
provisions with respect to matters or questions arising under this Warrant which
shall nor adversely affect in any material respect the interests of the holder
hereof or any holder of a Certificate or (ii) to evidence and provide for the
acceptance of appointment hereunder of a Warrant Agent other than U.S. Bank
Trust National Association.

           (b) Without limiting the generality of the foregoing, this Call
Warrant may also be modified or amended from time to time by the Depositor, the
Trustee and the Warrant Agent with the consent of the holders of 66-2/3% of the
Call Warrants, upon receipt of an opinion of counsel satisfactory to the Warrant
Agent that the provisions hereof (including, without limitation, the following
proviso) have seen satisfied, for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Call Warrant
or of modifying in any manner the rights of the holders of this Call Warrant;
provided, however, that no such amendment shall (i) adversely affect in any
material respect the interests of holders of Certificates without the consent of
the holders of Certificates evidencing nor less than the Required
Percentage-Amendment of the aggregate Voting Rights of such affected
Certificates (as such terms are defined in the Trust Agreement) and without
written confirmation from the Rating Agencies that such amendment will not
result in a downgrading or withdrawal of its rating of the Certificates; (ii)

deliverable upon exercise of a Warrant without the consent of the holders of
Certificates evidencing not less than 100% of the aggregate Voting Rights of

or (iii) reduce the percentage of aggregate Voting Rights required by (i) or
(ii) without the consent of the holders of all such affected Certificates.

modification to each holder of a Call Warrant, to the Trustee and to the Rating
Agencies. It shall not be necessary for the consent of holders of Call Warrants

designated by the holder of this instrument (this "Call Warrant") at a call
price equal to the Call Price (as defined below), all subject to the terms and
conditions set forth below.

           Certain capitalized terms used in this Call Warrant are defined in
Article IV hereof; capitalized terms used but not defined herein shall have the
respective meanings set forth in the Trust Agreement; references to an "Exhibit"
are, unless otherwise specified, to one of the Exhibits attached to this Call
Warrant and references to a "Section" are, unless otherwise specified, to one of
the sections of this Call Warrant.

                                   ARTICLE I

                            Exercise of Call Warrants

           Section 1.1 Manner of Exercise. (a) This Call Warrant may be
exercised by the holder hereof (each, a "Warrant Holder"), in whole or in part,
on any Call Date, set forth in a written notice delivered to the Warrant Agent
and the Trustee at any time on or before the Business Day that is at least 5
Business Days before such Call Date, by surrender of this Call Warrant to the
Warrant Agent at its office set forth in Section 6.3 hereof no later than 10:00
a.m. (New York City time) on such Call Date; provided that such holder shall
have made payment to the Warrant Agent, by wire transfer or other immediately
available funds acceptable to the Warrant Agent, in the amount of the applicable
Call Price, in a manner such that funds are available to the Warrant Agent no
later than 10:00 a.m. (New York City time) on such Call Date, and such holder
shall thereupon be entitled to delivery of the Certificates in a Certificate
Principal Amount equal to $25 per Call Warrant (if exercised in whole); provided
further that the Warrant Holder may only exercise Call warrants if it is
simultaneously exercising Call Warrants relating to Class A-1 Certificates and
Call Warrants relating to Class A-2 Certificates which represent a like
percentage of all Class A-1 Certificates and Class A-2 Certificates,
respectively; provided further that if the Warrant Holder is the Depositor or an
Affiliate thereof, such Warrant Holder shall not be entitled to delivery of the
Certificates being called (the "Called Certificates"), and shall only be
entitled to receive the cash proceeds of the sale of the Underlying Securities
related to such Called Certificates; and provided further that the Warrant
Holder may not exercise this Call Warrant at any time when such Warrant Holder
is insolvent, and in connection therewith, such Warrant Holder shall be required
to certify that it is solvent at the time of exercise settlement, by completing
the Form of Subscription attached to this Call Warrant and delivering such
completed Form of Subscription to the Trustee on or prior to the Call Date and
deliver to the Trustee a form reasonably satisfactory to the Trustee of the
opinion and the solvency certificate required pursuant to Section 7(b)(iv) of
the Series Supplement.

           (b) The Warrant Agent shall notify the Trustee immediately upon
receipt by the Warrant Agent of a notice by the holder of this Call Warrant and
upon receipt of payment of the applicable Call Price from such holder pursuant
to clause (a) of this Section 1.1. The Warrant Agent shall transfer each payment
made by the holder hereof pursuant to clause (a) of this Section 1.1 to the
Trustee in immediately available funds, for application pursuant to the Trust
Agreement on the applicable Call Date (and, pending such transfer, shall hold




                                     B-2-2
<PAGE>

each such payment for the benefit of the holder hereof in a segregated trust
account).

           (c) A notice by the holder of a Call Warrant does not impose any
obligations on a holder of a Call Warrant in any way to pay any Call Price. If,
by 10:00 a.m. (New York City time) on the Call Date, the holder of the Call
Warrant being exercised has not paid the Call Price, then such notice shall
automatically expire and none of the holder of such Call Warrant, the Warrant
Agent and the Trustee shall have any obligations with respect to such notice by
the holder of such Call Warrant. The expiration of a notice by the holder of
this Call Warrant shall in no way affect a holder of a Call Warrant's right to
subsequently deliver a notice which satisfies the terms of the Trust Agreement.

           Section 1.2 Transfer of Certificates. As soon as practicable after
each surrender of this Call Warrant, in whole or in part on the Call Date and
upon satisfaction of all other requirements described in this Call Warrant, the
Warrant Agent shall instruct the Trustee to cause a number of the Class A-1
Certificates equal to the number of the Call warrants being exercised hereunder
to reflect the new beneficial ownership fo the Class A-1 Certificates, and, in
case such exercise is in part only, a new Call Warrant of like tenor,
representing the remaining outstanding Call Warrants of the holder, shall be
delivered by the Warrant Agent to the holder hereof.

           Section 1.3 Cancellation and Destruction of Call Warrant. All Call
Warrants surrendered to the Warrant Agent for the purpose of exercise (in whole
or in part) pursuant to Section 1.1 and actually exercised, or for the purpose
of transfer or exchange pursuant to Article III, shall be cancelled by the
Warrant Agent, and no Call Warrant shall be issued in lieu thereof. The Warrant
Agent shall destroy all cancelled Call Warrants.

           Section 1.4 No Rights as Holder of Certificates Conferred by Call
Warrants. Prior to the exercise hereof, this Call Warrant shall not entitle the
holder hereof to any of the rights of a holder of the Certificates, including,
without limitation, the right to receive the payment of any amount on or in
respect of the Certificates or to enforce any of the covenants of the Trust
Agreement.

                                   ARTICLE II

register so the owner thereof for all purposes, and the Trustee and the Warrant
Agent shall not be affected by any notice to the contrary.

Warrant Agent, the Warrant Agent shall execute and deliver, and cause the
Trustee, on behalf of the Trust, to execute and deliver, in lieu thereof, a new
Call Warrant of like tenor bearing a number not contemporaneously outstanding.

           Section 3.4 Execution and Delivery of Call Warrants by Trustee. The
Trustee, on behalf of the Trust, hereby agrees (subject to compliance with
Article II) to execute and deliver such new Call Warrants issued in accordance
with Section 1.2 or this Article III as the Warrant Agent shall request in
accordance herewith.

Warrant Agent, which may be the interim Warrant Agent. If the Depositor shall
fail to make such appointment of a permanent successor within a period of thirty
(30) days after such removal or within sixty (60) days after notification in
writing of such resignation or incapacity by the resigning or incapacitated
Warrant Agent or by the holder of a Call Warrant, then the Warrant Agent or
registered holder of any Warrant may apply to any court of competent
jurisdiction for the appointment of such a successor. Any successor to the
Warrant Agent appointed hereunder must be rated in one on the four highest
rating categories by the Rating Agencies. Any entity which may be merged or
consolidated with or which shall otherwise succeed to substantially all of the
trust or agency business of the Warrant Agent shall be deemed to be the
successor Warrant Agent without any further action.

modification, the Warrant Agent shall furnish a copy of such amendment or
modification to each holder of a Call Warrant, to the Trustee and to the Rating
Agencies. It shall not be necessary for the consent of holders of Call Warrants

that it has been induced to enter into the transaction documents to which it is

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


                             WARRANT AGENT AGREEMENT

                       CORPORATE BACKED TRUST CERTIFICATES

               Liberty Media Debenture-Backed Series 2001-32 TRUST

           WARRANT AGENT AGREEMENT, dated as of [_______], 2001 (the "Warrant
Agent Agreement"), by and between LEHMAN ABS CORPORATION, as Depositor (the
"Depositor"), and U.S. BANK TRUST NATIONAL ASSOCIATION, as Warrant Agent (the
"Warrant Agent").

                              W I T N E S S E T H:

           WHEREAS, the Depositor created Corporate Backed Trust Certificates,
Liberty Media Debenture-Backed Series 2001-32 Trust (the "Trust"), a trust
created under the laws of the State of New York pursuant to a Standard Terms for
Trust Agreements, dated as of January 16, 2001 (the "Agreement"), between Lehman
ABS Corporation (the "Depositor") and U.S. Bank Trust National Association, a
national banking association, not in its individual capacity but solely as
Trustee (the "Trustee"), as supplemented by the Series Supplement 2001-32, dated
as of [_______], 2001 (the "Series Supplement" and, together with the Agreement,
the "Trust Agreement"), between the Depositor and the Trustee; and

           WHEREAS, in connection with the creation of the Trust and the deposit
therein of the Underlying Securities, it is desired to provide for the issuance
of Class A-1 Certificates and related Class A-1 Call Warrants and Class A-2
Certificates (together with the Class A-1 Certificates, the "Certificates") and
related Class A-2 Call Warrants (together with the Class A-1 Call Warrants, the
"Call Warrants"), such Certificates evidencing undivided interests in the Trust.

           NOW, THEREFORE, in consideration of the foregoing premises and the
mutual covenants expressed herein, it is hereby agreed by and between the
Depositor and the Trustee as follows:

           Section 1. Definitions. Except as otherwise specified herein or as
the context may otherwise require, capitalized terms used herein but not defined
herein shall have the respective meanings set forth below for all purposes under
the Series Supplement.

                                   ARTICLE I

                            Exercise of Call Warrants

           Section 1.1 Manner of Exercise. (a) The Call Warrants may be
exercised by the holder thereof (each, a "Warrant Holder"), in whole or in part,
on any Call Date, set forth in a written notice (a "Call Notice") delivered to
the Warrant Agent and the Trustee at any time on or before the Business Day that
is at least 5 Business Days before such Call Date, by surrender of the Call
Warrants to the Warrant Agent at its office set forth in Section 6.3 hereof no



                                      C-1
<PAGE>

later than 10:00 a.m. (New York City time) on such Call Date; provided that such
holder shall have made payment to the Warrant Agent, by wire transfer or other
immediately available funds acceptable to the Warrant Agent, in the amount of
the applicable Call Price, in a manner such that funds are available to the
Warrant Agent no later than 10:00 a.m. (New York City time) on such Call Date,
and such holder shall thereupon be entitled to delivery of, in the case of the
Class A-1 Call Warrants, Class A-1 Certificates in a Certificate Principal
Amount equal to $[25] per Class A-1 Call Warrant and, in the case of the Class
A-2 Call Warrants, Class A-2 Certificates in an amount per Call Warrant equal to
a $[100] principal amount of Class A-2 Certificates purchased hereunder in
accordance with this Article I (in each case subject to the provisions of
Section 7(b) of the Series Supplement); provided further that the Warrant Holder
shall exercise Class A-1 Warrants relating to the Class A-1 Certificates and
Class A-2 Call Warrants relating to the Class A-2 Certificates which represent a
like percentage for all Class A-1 Certificates and Class A-2 Certificates,
respectively; and provided further that the Warrant Holder may not exercise the
Call Warrants at any time when such Warrant Holder is insolvent, and in
connection therewith, such Warrant Holder shall be required to certify that it
is solvent at the time of exercise settlement, by completing the Form of
Subscription attached to the Call Warrants and delivering such completed Form of
Subscription to the Trustee on or prior to the Call Date and deliver to the
Trustee a form reasonably satisfactory to the Trustee of the opinion and the
solvency certificate required pursuant to Section 7(b)(iv) of the Series
Supplement.

           (b) Upon exercise of Call Warrants, any Warrant Holder other than the
Depositor or any Affiliate of the Depositor shall be entitled to delivery of the
Called Certificates. The "Called Certificates" shall be, in the case of Class
A-1 Certificates, Class A-1 Certificates having a Certificate Principal Amount
equal to $25 per Class A-1 Call Warrant and, in the case of Class A-2
Certificates, Class A-2 Certificates having a Certificate Principal Amount equal
to $100 per Class A-2 Call Warrant. Any Warrant Holder which is the Depositor or
any Affiliate of the Depositor shall receive the proceeds of the sale of the
Called Underlying Securities and shall not be entitled to receive the related
Called Certificates. "Called Underlying Securities" are Underlying Securities
which represent the same percentage of the Underlying Securities as the Called
Certificates represent of the Class A-1 Certificates and Class A-2 Certificates.

           (c) The Warrant Agent shall notify the Trustee immediately upon
receipt by the Warrant Agent of a Call Notice by the holder of the Call Warrants
and upon receipt of payment of the applicable Call Price from such holder
pursuant to clause (a) of this Section 1.1. The Warrant Agent shall transfer
each payment made by the holder thereof pursuant to clause (a) of this Section
1.1 to the Trustee in immediately available funds, for application pursuant to
the Trust Agreement on the applicable Call Date (and, pending such transfer,
shall hold each such payment for the benefit of the holder thereof in a
segregated trust account).

           (d) A Call Notice by the holder of a Call Warrant does not impose any
obligations on a holder of a Call Warrant in any way to pay any Call Price. If,
by 10:00 a.m. (New York City time) on the Call Date, the holder of the Call
Warrant being exercised has not paid the Call Price, then such Call Notice shall
automatically expire and none of the holder of such Call Warrant, the Warrant



                                      C-2
<PAGE>

Agent and the Trustee shall have any obligations with respect to such Call
Notice by the holder of such Call Warrant. The expiration of a Call Notice by
the holder of this Call Warrant shall in no way affect a holder of a Call
Warrant's right to subsequently deliver a Call Notice which satisfies the terms
of the Trust Agreement.

           Section 1.2 Transfer of Certificates. As soon as practicable after
each surrender of Call Warrants in whole or in part on the Call Date and upon
satisfaction of all other requirements described in the Call Warrants and in
Section 1.1 hereof, the Warrant Agent shall instruct the Trustee as follows:

           (a) if Call Warrants are being exercised by any Warrant Holder other
than the Depositor or any Affiliate of the Depositor, to cause the Called
Certificates to reflect the holder's beneficial ownership of such Certificates,
or

           (b) if the Call Warrants are being exercised by the Depositor or any
Affiliate of the Depositor, to cause the Called Underlying Securities to be sold
pursuant to Section 13 of the Series Supplement and to distribute the proceeds
of such sale to the Warrant Holder.

           If such exercise is in part only, the Warrant Agent shall instruct
the Trustee to authenticate new Call Warrants of like tenor, representing the
outstanding Call Warrants of the Warrant Holder and the Warrant Agent shall
deliver such Call Warrants to the Warrant Holder.

           Section 1.3 Cancellation and Destruction of Call Warrants. All Call
Warrants surrendered to the Warrant Agent for the purpose of exercise (in whole
or in part) pursuant to Section 1.1 and actually exercised, or for the purpose
of transfer or exchange pursuant to Article III, shall be cancelled by the
Warrant Agent, and no Call Warrant shall be issued in lieu thereof. The Warrant
Agent shall destroy all cancelled Call Warrants.

           Section 1.4 No Rights as Holder of Certificates Conferred by Call
Warrants. Prior to the exercise thereof, the Call Warrants shall not entitle the
holder thereof to any of the rights of a holder of the Certificates, including,
without limitation, the right to receive the payment of any amount on or in
respect of the Certificates or to enforce any of the covenants of the Trust
Agreement.

                                   ARTICLE II

                            Restrictions on Transfer

           Section 2.1 Restrictive Legends. Except as otherwise permitted by
this Article II, each Call Warrant (including each Call Warrant issued upon the
transfer of any Call Warrant) shall be issued with a legend in substantially the
following form:

           "This Call Warrant has not been registered under the Securities Act
of 1933, as amended, and may not be transferred, sold or otherwise disposed of
except while a registration under such Act is in effect or pursuant to an



                                      C-3
<PAGE>

exemption therefrom under such Act. The Call Warrant represented hereby may be
transferred only in compliance with the conditions specified in the Call
Warrants."

           Section 2.2 Notice of Proposed Transfer. Prior to any transfer of any
Call Warrant or portion thereof, the holder thereof will give 5 Business Days
(or such lesser period acceptable to the Warrant Agent) prior written notice to
the Warrant Agent of such holder's intention to effect such transfer.


                                  ARTICLE III

                Registration and Transfer of Call Warrants, etc.

           Section 3.1 Warrant Register; Ownership of Call Warrants. The Warrant
Agent will keep a register in which the Warrant Agent will provide for the
registration of Call Warrants and the registration of transfers of Call Warrants
representing whole numbers of Call Warrants. The Trustee and the Warrant Agent
may treat the Person in whose name any Call Warrant is registered on such
register so the owner thereof for all purposes, and the Trustee and the Warrant
Agent shall not be affected by any notice to the contrary.

           Section 3.2 Transfer and Exchange of Call Warrants. Upon surrender of
any Call Warrant for registration of transfer or for exchange to the Warrant
Agent, the Warrant Agent shall (subject to compliance with Article II) execute
and deliver, and cause the Trustee, on behalf of the Trust, to execute and
deliver, in exchange therefor, a new Call Warrant of like tenor and evidencing a
like whole number of Call Warrants, in the name of such holder or as such holder
(upon payment by such holder of any applicable transfer taxes or government
charges) may direct; provided that as a condition precedent for transferring the
Call Warrants, the prospective transferee shall be required to deliver to the
Trustee and the Depositor an executed copy of the Investment Letter (set forth
as Exhibit A hereto).

           Section 3.3 Replacement of Call Warrants Upon receipt of evidence
reasonably satisfactory to the Warrant Agent of the loss, theft, destruction or
mutilation of any Call Warrant and, in the case of any such loss, theft or
destruction of any Call Warrant, upon delivery of an indemnity bond in such
reasonable amount as the Warrant Agent may determine, or, in the case of any
such mutilation, upon the surrender of such Call Warrant for cancellation to the
Warrant Agent, the Warrant Agent shall execute and deliver, and cause the
Trustee, on behalf of the Trust, to execute and deliver, in lieu thereof, a new
Call Warrant of like tenor bearing a number not contemporaneously outstanding.

           Section 3.4 Execution and Delivery of Call Warrants by Trustee. The
Trustee, on behalf of the Trust, hereby agrees (subject to compliance with
Article II) to execute and deliver such new Call Warrants issued in accordance
with Section 1.2 or this Article III as the Warrant Agent shall request in
accordance herewith.

acknowledged, by the proper Person or Persons.

           Section 5.2 Duties of Warrant Agent. The Warrant Agent undertakes
only the specific duties and obligations imposed hereunder upon the following
terms and conditions, by all of which the Depositor, the Trust, the Trustee and
each holder of a Call Warrant shall be bound:

           (a) The Warrant Agent may consult with legal counsel (who may be
legal counsel for the Depositor), and the opinion of such counsel shall be full
and complete authorization and protection to the Warrant Agent as to any action
taken or omitted by it in good faith and in accordance with such opinion,
provided the Warrant Agent shall have exercised reasonable care in the selection
by it of such counsel.

           (b) Whenever in the performance of its duties hereunder, the Warrant
Agent shall deem it necessary or desirable that any fact or matter be proved or
established by the Depositor or the Trustee prior to taking or suffering any
action hereunder, such fact or matter may be deemed to be conclusively proved
and established by a Depositor Order or a certificate signed by a Responsible
Officer of the Trustee and delivered to the Warrant Agent; and such certificate
shall be full authorization to the Warrant Agent for any action taken or
suffered in good faith by it hereunder in reliance upon such certificate.

           (c) The Warrant Agent shall be liable hereunder only for its own
negligence, willful misconduct or bad faith.

           (d) The Warrant Agent shall not be liable for or by reason of any of

same, but all such statements and recitals are and shall be deemed to have been
made by the Trust and the Depositor only.

           (e) The Warrant Agent shall not have any responsibility in respect of
and makes no representation as to the validity of the Call Warrants or the
execution and delivery thereof (except the due execution hereof by the Warrant



                                      C-6
<PAGE>

Agent); nor shall it be responsible for any breach by the Trust of any covenant
or condition contained in the Call Warrants; nor shall it by any act thereunder
be deemed to make any representation or warranty as to the Certificates to be
purchased thereunder.

           (f) The Warrant Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from the
Chairman of the Board, the Chief Executive Officer, Chief Financial Officer,
Chief Operating Officer, President, a Vice President, a Senior Vice President, a
Managing Director, its Treasurer, an Assistant Treasurer, its Secretary or an
Assistant Secretary of the Depositor, and any Responsible Officer of the
Trustee, and to apply to such officers for advice or instructions in connection
with its duties, and it shall not be liable for any action taken or suffered to
be taken by it in good faith in accordance with instructions of any such
officer.

           (g) The Warrant Agent and any shareholder, director, officer or
employee of the Warrant Agent may buy, sell or deal in any of the Call Warrants
or other securities of the Trust or otherwise act as fully and freely as though
it were not Warrant Agent hereunder, so long as such persons do so in full
compliance with all applicable laws. Nothing herein shall preclude the Warrant
Agent from acting in any other capacity for the Trust, the Depositor or for any
other legal entity.

           (h) The Warrant Agent may execute and exercise any of the rights or
powers hereby vested in it or perform any duty hereunder either itself or by or
through its attorneys or agents.

perform such duties as are specifically set forth herein, and no implied
covenants or obligations shall be read into the Call Warrants against the
Warrant Agent, whose duties shall be determined solely by the express provisions
thereof. The Warrant Agent shall not be deemed to be a fiduciary.

part of the Trustee to comply with any of its covenants and obligations
contained herein.

           (k) The Warrant Agent shall not be under any obligation or duty to

hereof, unless first indemnified to its satisfaction, but this provision shall
not affect the power of the Warrant Agent to take such action as the Warrant
Agent may consider proper, whether with or without such indemnity. The Warrant
Agent shall promptly notify the Depositor and the Trustee in writing of any
claim made or action, suit or proceeding instituted against it arising out of or
in connection with the Call Warrants.

           (l) The Trustee will perform, execute, acknowledge and deliver or
cause to be performed, executed, acknowledged and delivered all such further
acts, instruments and assurances as may be required by the Warrant Agent in
order to enable it to carry out or perform its duties hereunder.

           Section 5.3 Change of Warrant Agent. The Warrant Agent may resign and
be discharged from its duties hereunder upon thirty (30) days notice in writing
mailed to the Depositor and the Trustee by registered or certified mail, and to
the holders of the Call Warrants by first-class mail at the expense of the
Depositor; provided that no such resignation or discharge shall become effective
until a successor Warrant Agent shall have been appointed hereunder. The
Depositor may remove the Warrant Agent or any successor Warrant Agent upon
thirty (30) days notice in writing, mailed to the Warrant Agent or successor
Warrant Agent, as the case may be, and to the holders of the Call Warrants by
first-class mail; provided further that no such removal shall become effective
until a successor Warrant Agent shall have been appointed hereunder. If the
Warrant Agent shall resign or be removed or shall otherwise become incapable of
acting, the Depositor shall promptly appoint a successor to the Warrant Agent,
which may be designated as an interim Warrant Agent. If an interim Warrant Agent
is designated, the Depositor shall then appoint a permanent successor to the
Warrant Agent, which may be the interim Warrant Agent. If the Depositor shall
fail to make such appointment of a permanent successor within a period of thirty
(30) days after such removal or within sixty (60) days after notification in
writing of such resignation or incapacity by the resigning or incapacitated
Warrant Agent or by the holder of a Call Warrant, then the Warrant Agent or
registered holder of any Warrant may apply to any court of competent
jurisdiction for the appointment of such a successor. Any successor to the
Warrant Agent appointed hereunder must be rated in one on the four highest
rating categories by the Rating Agencies. Any entity which may be merged or
consolidated with or which shall otherwise succeed to substantially all of the
trust or agency business of the Warrant Agent shall be deemed to be the
successor Warrant Agent without any further action.

                                    ARTICLE VI

                                  Miscellaneous

           Section 6.1 Remedies. The remedies at law of the holder of the Call
Warrants in the event of any default or threatened default by the Warrant Agent
in the performance of or compliance with any of the terms of the Call Warrants
are not and will not be adequate and, to the full extent permitted by law, such
terms may be specifically enforced by a decree for the specific performance of
any agreement contained herein or by an injunction against a violation of any of
the terms thereof or otherwise.

           Section 6.2 Limitation on Liabilities of Holder. Nothing contained in
this Warrant Agent Agreement shall be construed as imposing any obligation on
the holder thereof to purchase any of the Certificates except in accordance with
the terms thereof.

           Section 6.3 Notices. All notices and other communications under this
Warrant Agent Agreement shall be in writing and shall be delivered, or mailed by
registered or certified mail, return receipt requested, by a nationally
recognized overnight courier, postage prepaid, addressed (a) if to any holder of
any Call Warrants, at the registered address of such holder as set forth in the
register kept by the Warrant Agent or (b) if to the Warrant Agent, to 100 Wall

<PAGE>

such other address notice of which the Warrant Agent shall have given to the
holder thereof and the Trustee or (c) if to the Trust or the Trustee, to the
Corporate Trust Office (as set forth in the Trust Agreement); provided that the
exercise of any Call Warrants shall be effective on the manner provided in
Article I.

           Section 6.4 Amendment. (a) This Warrant Agent Agreement may be
amended from time to time by the Depositor, the Trustee and the Warrant Agent
without the consent of any holder thereof, upon receipt of an opinion of counsel
satisfactory to the Warrant Agent that the provisions hereof have been satisfied
and that such amendment would not alter the status of the Trust as a grantor
trust under the Code, for any of the following purposes: (i) to cure any
ambiguity or to correct or supplement any provision herein which may be
defective or inconsistent with any other provision herein or to provide for any
other terms or modify any other provisions with respect to matters or questions
arising under the Call Warrant which shall nor adversely affect in any material
respect the interests of the holder thereof or any holder of a Certificate or
(ii) to evidence and provide for the acceptance of appointment hereunder of a
Warrant Agent other than U.S. Bank Trust National Association.

           (b) Without limiting the generality of the foregoing, the Call
Warrants may also be modified or amended from time to time by the Depositor, the
Trustee and the Warrant Agent with the consent of the holders of 66-2/3% of each
class of the Call Warrants, upon receipt of an opinion of counsel satisfactory
to the Warrant Agent that the provisions hereof (including, without limitation,
the following proviso) have seen satisfied, for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
the Call Warrants or of modifying in any manner the rights of the holders of the
Call Warrants; provided, however, that no such amendment shall (i) adversely
affect in any material respect the interests of holders of Certificates without
the consent of the holders of Certificates evidencing nor less than the Required
Percentage-Amendment of the aggregate Voting Rights of such affected
Certificates (as such terms are defined in the Trust Agreement) and without
written confirmation from the Rating Agencies that such amendment will not
result in a downgrading or withdrawal of its rating of the Certificates; (ii)
alter the dates on which Call Warrants are exercisable or the amounts payable
upon exercise of a Warrant without the consent of the holders of Certificates
evidencing not less than 100% of the aggregate Voting Rights of such affected
Certificates and the holders of 100% of the affected Call Warrants or (iii)
reduce the percentage of aggregate Voting Rights required by (i) or (ii) without
the consent of the holders of all such affected Certificates. Notwithstanding
any other provision of this Warrant, this Section 6.4(b) shall not be amended
without the consent of the holders of 100% of the affected Call Warrants.

           (c) Promptly after the execution of any such amendment or
modification, the Warrant Agent shall furnish a copy of such amendment or
modification to each holder of a Call Warrant, to the Trustee and to the Rating
Agencies. It shall not be necessary for the consent of holders of Call Warrants
or Certificates under this Section to approve the particular form of any
proposed amendment, but it shall be sufficient if such consent shall approve the
substance thereof. The manner of obtaining such consents and of evidencing the
authorization of the execution thereof shall be subject to such reasonable
regulations as the Warrant Agent may prescribe.

jurisdiction in the County of New York, State of New York or of the United
States of America for the Southern District of New York and, by execution and

judgment rendered thereby in connection with this Warrant Agent Agreement or the

objection that the Trust or the Trustee, the Warrant Agent may now or hereafter
have as to the venue of any such suit, action or proceeding brought in such a
court or that such court is an inconvenient forum.

of the Call Warrants by its acceptance thereof, and (ii) the Warrant Agent
agrees, that it shall not (and, in the case of the holder, that it shall not

Ladies and Gentlemen:

                     In connection with our proposed purchase of $___________
aggregate principal amount of Call Warrants (the "Call Warrants") representing
an interest in the Corporate Backed Trust Certificates Series 2001-32 Trust (the
"Trust"), the investor on whose behalf the undersigned is executing this letter
(the "Purchaser") confirms that:

(a)   Reference is made to the Prospectus Supplement, dated [_______], 2001 (the
      "Prospectus Supplement"), with respect to the Certificates to which the
      Call Warrants relate. Capitalized terms used herein that are not otherwise
      defined shall have the meanings ascribed thereto in the Prospectus
      Supplement. The Purchaser has received a copy of the Prospectus Supplement
      and such other information as the Purchaser deems necessary in order to
      make its investment decision and the Purchaser has been provided the
      opportunity to ask questions of, and receive answers from, the Depositor
      and the Underwriters, concerning the terms and conditions of the Call
      Warrants. The Purchaser has received and understands the above, and
      understands that substantial risks are involved in an investment in the
      Call Warrants. The Purchaser represents that in making its investment
      decision to acquire the Call Warrants, the Purchaser has not relied on
      representations, warranties, opinions, projections, financial or other
      information or analysis, if any, supplied to it by any person, including
      you, the Depositor or the Trustee or any of your or their affiliates,
      except as expressly contained in the Prospectus Supplement and in the

      capable of evaluating the merits and risks of an investment in the Call
      Warrants, and the Purchaser is able to bear the substantial economic risks

(b)   The Purchaser is (A) a "Qualified Institutional Buyer" (as defined in Rule
      144A under the Securities Act of 1933, as amended (the "1933 Act")) and
      (B) acquiring the Call Warrants for its own account or for the account of
      an investor of the type described in clause (A) above as to each of which
      the Purchaser exercises sole investment discretion. The Purchaser is
      purchasing the Call Warrants for investment purposes and not with a view
      to, or for, the offer or sale in connection with, a public distribution or
      in any other manner that would violate the 1933 Act or the securities or
      blue sky laws of any state.

(c)   The Purchaser understands that the Call Warrants have not been and will
      not be registered under the 1933 Act or under the securities or blue sky
      laws of any state, and that (i) if it decides to resell, pledge or
      otherwise transfer any Call Warrant, such Call Warrant may be resold,
      pledged or transferred without registration only to an entity that has
      delivered to the Depositor and the Trustee a certification that it is a
      Qualified Institutional Buyer that purchases (1) for its own account or
      (2) for the account of such a Qualified Institutional Buyer, that is, in
      either case, aware that the resale, pledge or transfer is being made in
      reliance on said Rule 144A and (ii) it will, and each subsequent holder
      will be required to, notify any purchaser of any Call Warrant from it of
      the resale restrictions referred to in clause (i) above.

(d)   The Purchaser understands that each of the Call Warrants will bear a
      legend to the following effect, unless otherwise agreed by the Depositor
      and the Trustee:

                     "THIS CALL WARRANT HAS NOT BEEN REGISTERED UNDER THE
                     SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
                     TRANSFERRED, SOLD OR OTHERWISE DISPOSED OF EXCEPT WHILE A
                     REGISTRATION UNDER SUCH ACT IS IN EFFECT OR PURSUANT TO AN
                     EXEMPTION THEREFROM UNDER SUCH ACT. THIS CALL WARRANT
                     REPRESENTED HEREBY MAY BE TRANSFERRED ONLY IN COMPLIANCE
                     WITH THE CONDITIONS SPECIFIED IN THIS CALL WARRANT."

(e)   The Purchaser understands that no subsequent transfer of the Call Warrants
      is permitted unless it causes its proposed transferee to provide to the
      Depositor and the Initial Warrant Holder a letter substantially in the
      form of Exhibit D-1 to the Series Supplement, as applicable, or such other
      written statement as the Depositor shall prescribe.

(f)   The Purchaser agrees that if at some time in the future it wishes to
      transfer or exchange any of the Call Warrants, it will not transfer or
      exchange any of the Call Warrants unless such transfer or exchange is in
      accordance with Section 5.04 of the Trust Agreement. The Purchaser
      understands that any purported transfer of the Call Warrants (or any

      interest therein) in contravention of any of the restrictions and
      conditions in the Trust Agreement, as applicable, shall be void, and the
      purported transferee in such transfer shall not be recognized by the Trust
      or any other Person as a Warrant Holder for any purpose.

account of an investor of the type described in clause (A) above as to each of
which the Purchaser exercises sole investment discretion. The Purchaser is
purchasing the Call Warrants for investment purposes and not with a view to, or
for, the offer or sale in connection with, a public distribution or in any other
manner that would violate the 1933 Act or the securities or blue sky laws of any
state.

                  (iii) The Purchaser understands that the Call Warrants have
not been and will not be registered under the 1933 Act or under the securities
or blue sky laws of any state, and that (i) if it decides to resell, pledge or
otherwise transfer any Call Warrant, such Call Warrant may be resold, pledged or
transferred without registration only to an entity that has delivered to the
Depositor and the Trustee a certification that it is a Qualified Institutional
Buyer that purchases (1) for its own account or (2) for the account of such a
Qualified Institutional Buyer, that is, in either case, aware that the resale,
pledge or transfer is being made in reliance on said Rule 144A and (ii) it will,
and each subsequent holder will be required to, notify any purchaser of any Call
Warrant from it of the resale restrictions referred to in clause (i) above.

                  (iv) The Purchaser understands that each of the Call Warrants
will bear a legend to the following effect, unless otherwise agreed by the
Depositor and the Trustee:

                  "THIS CALL WARRANT HAS NOT BEEN REGISTERED UNDER THE
                  SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
                  TRANSFERRED, SOLD OR OTHERWISE DISPOSED OF EXCEPT WHILE A
                  REGISTRATION UNDER SUCH ACT IS IN EFFECT OR PURSUANT TO AN
                  EXEMPTION THEREFROM UNDER SUCH ACT. THIS CALL WARRANT
                  REPRESENTED HEREBY MAY BE TRANSFERRED ONLY IN COMPLIANCE WITH
                  THE CONDITIONS SPECIFIED IN THIS CALL WARRANT."

                  (v) The Purchaser understands that no subsequent transfer of
the Call Warrants is permitted unless it causes its proposed transferee to
provide to the Depositor and the Initial Warrant Holder a letter substantially
in the form of Exhibit D-1 to the Series Supplement, as applicable, or such
other written statement as the Depositor shall prescribe.

                  (vi) The Purchaser agrees that if at some time in the future
it wishes to transfer or exchange any of the Call Warrants, it will not transfer
or exchange any of the Call Warrants unless such transfer or exchange is in
accordance with Section 5.04 of the Trust Agreement. The Purchaser understands
that any purported transfer of the Call Warrants (or any interest therein) in
contravention of any of the restrictions and conditions in the Trust Agreement,
as applicable, shall be void, and the purported transferee in such transfer
shall not be recognized by the Trust or any other Person as a Warrantholder, as
the case may, be for any purpose.

Qualified Institutional Buyer (a "QIB") or an Accredited Investor and (B)

Class A-2 Certificates are being sold to it in reliance on the exemption from
the provisions of Section 5 of the 1933 Act provided by Rule 144A or Rule 501(a)
under Regulation D. The Purchaser is purchasing the Class A-2 Certificates for
investment purposes and not with a view to, or for, the offer or sale in
connection with, a public distribution or in any other manner that would violate
the 1933 Act or the securities or blue sky laws of any state.

                  (iii) The Purchaser understands that the Class A-2
Certificates have not been and will not be registered under the 1933 Act or
under the securities or blue sky laws of any state, and that (i) if it decides
to resell, pledge or otherwise transfer any Class A-2 Certificate, such Class
A-2 Certificate may be resold, pledged or transferred without registration only

that it is a QIB or Accredited Investor that purchases (1) for its own account
or (2) for the account of such a QIB or Accredited Investor, that is, in either
case, aware that the reoffer, resale, pledge or transfer is being made in
reliance on Rule 144A or Rule 501(a) under Regulation D and (ii) it will, and
each subsequent holder will be required to, notify any purchaser of any Class
A-2 Certificate from it of the resale restrictions referred to in clause (i)
above.

will bear a legend to the following effect, unless otherwise agreed by the
Initial Purchaser, the Depositor and the Trustee:

                  CLAUSE (A) ABOVE."

                  (v) The Purchaser understands that no subsequent transfer of
the Class A-2 Certificates is permitted unless (A) such transfer is of a Class
