                  STANDARD TERMS AND PROVISIONS OF TRUST AGREEMENT

                  This document constitutes Standard Terms and Provisions of
Trust Agreement (these "Standard Terms") which are to be incorporated by
reference in, and attached as a Schedule to, one or more Series Trust Agreements
by and between Corporate Asset Backed Corporation, as Depositor, and the Trustee
specified in the applicable Series Trust Agreement, as Trustee.

                  These Standard Terms shall be of no force and effect unless
and until incorporated by reference into the Forepart of a particular Series
Trust Agreement (each as defined herein).

                  The particular Series Trust Agreement into which these
Standard Terms have been incorporated establishes a trust under the laws of the
State of New York to hold the Underlying Securities specified in the Forepart
and any other Trust Assets specified in the Forepart and provides for the
creation, execution and delivery of trust certificates (the "Certificates") of
one or more classes and, in connection therewith, the execution, delivery and
performance of a swap agreement (the "Swap Agreement") with the swap
counterparty specified in the Forepart and any Related Agreements specified in
the Forepart, and, if so specified in the Forepart, the execution, granting or
arrangement of one or more Credit Enhancement Agreements.

                  The following terms and provisions shall govern the
Certificates and the Trust subject to contrary terms and provisions expressly
set forth in the Forepart of the Series Trust Agreement, which contrary terms
and provisions shall control; provided, that no such term or provisions of the
Forepart may limit, qualify or conflict with Section 10.11 hereof.

                                    ARTICLE I
                   DEFINITIONS AND INCORPORATION BY REFERENCE

                  SECTION 1.1 Definitions. Except as otherwise specified herein

these Standard Terms.

                  "Affiliate" means, with respect to any specified Person, any
other Person controlling or controlled by or under common control with such
specified Person. For the purposes of this definition, "control" when used with
respect to any specified Person means the power to direct the management and

"controlled" have meanings correlative to the foregoing.

                  "Authorized Signatory" means, in relation to the Trustee, any
Person authorized from time to time to execute documents or agreements,
authenticate Certificates or otherwise act for and on behalf of the Trustee from
time to time, and who is identified on the list of Authorized Signatories

be modified or supplemented from time to time thereafter).

                  "Available Information Event" means that any Underlying
Securities Issuer evidencing more than 10% of the aggregate principal amount of
the Underlying Securities has suspended its Exchange Act reporting requirements
at a time when the Exchange Act reporting requirements with respect to the
Certificates have not been suspended or terminated.

                  "Basic Documents" means the Series Trust Agreement, the Swap
Agreement, each Related Agreement, and each Credit Enhancement Agreement.

DTC, as described in Section 3.9, substantially in the form set forth in Exhibit
C to the Series Trust Agreement and shall be issued in the Class or Classes and
in the authorized denominations set forth in the Forepart. The Certificates
shall be executed on behalf of the Trust by manual or facsimile signature of an
authorized officer or Authorized Signatory of the Trustee, pursuant to a written
order signed by the Depositor, and authenticated by a Responsible Officer or
Authorized Signatory of the Trustee. Certificates bearing the manual or
facsimile signatures of individuals who were, at the time when such signatures
shall have been affixed, authorized to execute or authenticate Certificates on
behalf of the Trust, shall be valid and binding obligations of the Trust,
notwithstanding that such individuals or any of them shall have ceased to be so
authorized prior to the authentication and delivery of such Certificates or did
not hold such offices at the date of authentication and delivery of such
Certificates. Each Certificate shall bear upon its face the designation so
selected for the Class and Series to which it belongs, and may have such
letters, numbers or other marks of identification. All Certificates of the same
Class shall be identical in all respects except for the denominations thereof.
All Certificates of all Classes at any time Outstanding shall be identical
except for differences among the Certificates of the different Classes specified
in the Forepart. Except as provided in subsection (b) below, all Certificates
(and all Classes) issued under the Series Trust Agreement shall be in all
respects equally and ratably entitled to the benefits hereof without preference,
priority or distinction on account of the actual time or times of authentication
and delivery, all in accordance with the terms and provisions of the Series
Trust Agreement.

                  (b) If so specified in the Forepart, the rights of the
Certificateholders holding Certificates of one Class may be senior or
subordinated to the rights of the Certificateholders holding any one or more
other Classes, all as specified in the Forepart.

                  (c) The terms of the Form of Certificate set forth in Exhibit
C to the Series Trust Agreement shall form part of the Series Trust Agreement.

                  SECTION 3.2 Execution, Authentication and Delivery.
Concurrently with the sale of the Underlying Securities and other Trust Assets
to the Trust, the Trustee, upon written order of the Depositor, shall cause to
be executed by an Authorized Signatory of the Trustee, and shall cause to be

authenticated and delivered by a Responsible Officer or Authorized Signatory of
the Trustee, the Certificates of each Class specified in the Forepart in an
aggregate certificate principal balance equal to the initial Certificate
Principal Balance of that Class, without further corporate action by the
Depositor, in the authorized denominations specified in the Forepart. No
Certificate shall entitle its holder to any benefit under the Series Trust
Agreement, or shall be valid for any purpose, unless there shall appear on such
Certificate a certificate of authentication substantially in the form set forth
in Exhibit C contained in the Forepart, executed by the Trustee by manual
signature. Such authentication shall constitute conclusive evidence that such
Certificate shall have been duly authenticated and delivered hereunder. All
Certificates shall be dated the date of their authentication.

                  SECTION 3.3 Registration, Registration of Transfer and
Exchange of Certificates.

                  (a) The Certificate Registrar (as defined below) shall keep or
cause to be kept, at the office or agency maintained pursuant to Section 2.2, a
Certificate register (the "Certificate Register") in which, subject to such
reasonable regulations as it may prescribe, the Trustee (in such capacity, the
"Certificate Registrar") shall provide for the registration of Certificates and
of transfers and exchanges of Certificates as provided herein; provided,
however, that no Certificate may be subdivided upon transfer or exchange such
that the denomination of any resulting Certificate is other than the authorized
denominations specified in the Forepart. Unless otherwise specified in the
Forepart, the initial Certificate Registrar shall be the Trustee. Upon any
resignation of a Certificate Registrar, the Trustee shall promptly appoint a
successor or, if it elects not to make such an appointment, assume the duties of
Certificate Registrar.

                  (b) Upon surrender for registration of transfer of any
Certificate at the office or agency maintained pursuant to Section 2.2, the
Depositor shall execute on behalf of the Trust, and the Trustee shall
authenticate and deliver in the name of the designated transferee or
transferees, one or more new Certificates of the same Class and in authorized
denominations of a like aggregate Certificate Principal Balance dated the date
of authentication by the Trustee.

                  (c) At the option of a Certificateholder, Certificates may be
exchanged for other Certificates of the same Class and in authorized
denominations of a like aggregate Certificate Principal Balance upon surrender
of the Certificates to be exchanged at the office or agency maintained pursuant
to Section 2.2. Whenever any Certificates are so surrendered for exchange, the
Depositor shall execute on behalf of the Trust, and the Trustee shall
authenticate and deliver, one or more Certificates dated the date of
authentication by the Trustee. Such Certificates shall be delivered to the
Certificateholder making the exchange.

                  (d) Every Certificate presented or surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to the Trustee and the Certificate
Registrar duly executed by the Certificateholder or its attorney duly authorized
in writing. Each Certificate surrendered for registration of transfer and
exchange shall be cancelled and subsequently destroyed by the Trustee or
Certificate Registrar in accordance with its customary practice.

                  (e) No service charge shall be made for any registration of
transfer or exchange of Certificates, but the Trustee or the Certificate
Registrar may require payment of a sum sufficient to cover any tax or
governmental charge that may be imposed in connection with any transfer or
exchange of Certificates.

                  (f) The provisions of Sections 7.1, 7.3, 7.8 and 7.10 shall
apply to the Trustee in its role as Certificate Registrar, for so long as the
Trustee shall act as Certificate Registrar.

                  SECTION 3.4  Calculation of Interest; Stripped Certificates

                  (a) Unless otherwise specified in the Forepart, the interest
rate applicable to the Certificates will be the fixed rate or equivalent
floating rate applicable to payments received by the Trust under the related
Swap Agreement (as determined by the Calculation Agent) or under the Underlying
Securities, if there is no Swap Agreement. The Calculation Agent (or the
Trustee, if applicable) shall calculate the interest rate applicable to the
Certificates from time to time as specified in the Forepart. All determinations
of interest by the Calculation Agent, if any, and otherwise the Trustee,
hereunder shall, in the absence of manifest error, be conclusive for all
purposes and binding on the Certificateholders. Each of the protections,
releases, indemnities and other terms applicable to the Trustee under Sections
7.1 and 7.3 shall apply to the Calculation Agent (or the Trustee, if applicable)
in connection with its actions as Calculation Agent for the Trust.

                  (b) With respect to any Stripped Certificate that is entitled
to principal distributions, with disproportionate, nominal or no interest
distributions, on or after the stated maturity date of the principal due on the
Underlying Securities related thereto, if the Underlying Securities Issuer shall
have paid in full and the Trustee shall have received the amount of such
principal upon maturity of the Underlying Securities related thereto, the
Trustee shall pay to the holder of such Stripped Certificate, upon presentation
and surrender thereof, no later than one Business Day after receipt of funds by
the Trustee, the entire amount of such principal, less any taxes or governmental
charges required to be withheld from such payment by the Trustee.

                  (c) With respect to any Stripped Certificate that is entitled
to interest distributions, with disproportionate, nominal or no principal
distributions, on or after the interest payment date on the Underlying Security
related thereto, if the Underlying Securities Issuer shall have paid in full and
the Trustee shall have received the amount of such interest due, the Trustee
shall pay to the holder of such Stripped Certificate, upon presentation and
surrender thereof, no later than one Business Day after receipt of funds by the
Trustee, the entire amount of such interest, less any taxes or governmental
charges required to be withheld from such payment by the Trustee.

                  SECTION 3.5 Mutilated, Destroyed, Lost or Stolen Certificates.

                  (a) If (i) any mutilated Certificate is surrendered to the
Certificate Registrar, or the Certificate Registrar receives evidence to its
satisfaction of the destruction, loss or theft of any Certificate, and (ii)
there is delivered to the Certificate Registrar, the Trustee and the Depositor
such security or indemnity as may be required by them to hold each of them
harmless, then, in the absence of notice to the Certificate Registrar or the
Trustee that such Certificate has been acquired by a protected purchaser, the
Depositor shall execute on behalf of the Trust and the Trustee shall
authenticate and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Certificate, a replacement Certificate of the same
Class and a like aggregate Certificate Principal Balance; provided, however,
that if any such destroyed, lost or stolen Certificate, but not a mutilated
Certificate, shall have become or within seven days shall be due and payable,
then instead of issuing a replacement Certificate the Trustee may pay such
destroyed, lost or stolen Certificate when so due or payable.

                  (b) If, after the delivery of a replacement Certificate or
payment in respect of a destroyed, lost or stolen Certificate pursuant to
Section 3.5(a), a protected purchaser of the original Certificate in lieu of
which such replacement Certificate was issued presents for payment such original
Certificate, the Trustee shall be entitled to recover such replacement
Certificate (or such payment) from the Person to whom it was delivered or any
Person taking such replacement Certificate from such Person to whom such
replacement Certificate was delivered or any assignee of such Person, except a
protected

purchaser, and shall be entitled to recover upon the security or indemnity
provided therefor to the extent of any loss, damage, cost or expense incurred by
the Trustee in connection therewith.

                  (c) In connection with the issuance of any replacement
Certificate under this Section 3.5, the Trustee may require the payment by the
Certificateholder of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other reasonable expenses
(including the fees and expenses of the Trustee and the Certificate Registrar)
connected therewith.

                  (d) Any Certificate issued pursuant to this Section 3.5 in
replacement of any mutilated, destroyed, lost or stolen Certificate shall
constitute an original additional contractual obligation of the Trust, whether
or not the mutilated, destroyed, lost or stolen Certificate shall be found at
any time or be enforced by anyone, and shall be entitled to all the benefits of
the Series Trust Agreement equally and proportionately with any and all other
Certificates duly issued hereunder.

                  (e) The provisions of this Section 3.5 are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Certificates.

                  SECTION 3.6 Persons Deemed Certificateholders. Prior to due
presentation of a Certificate for registration of transfer, the Trustee or the
Certificate Registrar may treat the Person in whose name the Certificate shall
be registered in the Certificate Register as the Certificateholder of such
Certificate for the purpose of receiving distributions pursuant to Article VI
and for all other purposes whatsoever, and neither the Trustee nor the
Certificate Registrar shall be affected by any notice to the contrary.

                  SECTION 3.7 Access to List of Certificateholders' Names and
Addresses.

                  (a) The Depositor shall furnish or cause to be furnished to
the Trustee not more than five (5) days before each Distribution Date, and at
such other times as the Trustee may request in writing, a list, in such form as
the Trustee may reasonably require, to the extent such information is in the
possession or control of the Depositor or any of its Paying Agents, of the names
and addresses of the Certificateholders as of the most recent Record Date;
provided, however, that so long as the Trustee is the Certificate Registrar,
such list shall not be required to be furnished to the Trustee. If the Trustee
is the Certificate Registrar, upon written request by the Depositor, the Trustee
shall furnish or cause to be furnished to the Depositor, within fifteen (15)
days after receipt of such request, a list, in such form as the Depositor may
reasonably require, of the names and addresses of the Certificateholders as of
the most recent Record Date. Each Certificateholder, by receiving and holding a
Certificate, shall be deemed to have agreed not to hold any of the Depositor or
the Trustee accountable by reason of the disclosure of its name and address,
regardless of the source from which such information was derived.

                  (b) For purposes of determining the identity of
Certificateholders entitled to vote or in connection with any notice or other
communication to be provided to Certificateholders pursuant to the Series Trust
Agreement by the Trustee with respect to any consent or other action to be taken
by Certificateholders, the Trustee shall establish a record date for such
consent or other action and, if any Certificates are held as Book-Entry
Certificates, give DTC notice of such record date not less than fifteen (15)
calendar days in advance of such record date to the extent possible. Such record
date shall be the later of thirty (30) days prior to the first solicitation of
such consent or other action and the date of the most recent list of
Certificateholders furnished to the Trustee pursuant to Section 3.7(a).

                  SECTION 3.8 Preservation of Information; Communications to

                  (a) The Trustee shall preserve, in as current a form as is
reasonably practicable, the names and addresses of the Certificateholders
contained in the most recent list furnished to the Trustee as provided in
Section 3.7 and the names and addresses of Certificateholders received by the
Trustee in its capacity as Certificate Registrar. The Trustee may destroy any
list furnished to it as provided in such Section 3.7 upon receipt or preparation
of a new list so furnished.

                  (b) Certificateholders shall have the right to communicate
pursuant to TIA Section 312(b) with other Certificateholders with respect to
their rights under the Series Trust Agreement or under the Certificates, and the
Trustee shall take such action, from time to time, as may be required by the
provisions of TIA Section 312(b).

                  (c) The Depositor, the Trustee and the Certificate Registrar
shall have the protection of TIA Section 312(c).

                  SECTION 3.9 Book-Entry Certificates. The Certificates of each
Class, upon original issuance, shall be issued in the form of a global
Certificate or Certificates representing Book-Entry Certificates, to be
delivered to DTC by or on behalf of the Trust. Such global Certificate or
Certificates shall be registered on the Certificate Register in the name of Cede
& Co., the nominee of DTC, and no Certificate Owner shall receive a physical
Certificate representing such Certificate Owner's interest in a Certificate,
except as provided in Section 3.11. Unless and until definitive fully-registered
Certificates (the "Definitive Certificates") shall have been issued to
Certificate Owners pursuant to Section 3.11:

                  (a) the provisions of this Section 3.9 shall be in full force
and effect;

                  (b) the Certificate Registrar and the Trustee shall be
entitled to deal with Cede & Co. for all purposes of the Series Trust Agreement
(including the distribution of principal of and periodic distributions on the
Certificates and the giving of instructions or directions hereunder) as the sole
Certificateholder and shall have no obligation to the Certificate Owners, and
whenever a notice or other communication to the Certificateholders is required
under the Series Trust Agreement, unless and until Definitive Certificates shall
have been issued to Certificate Owners pursuant to Section 3.11, the Trustee
shall give all such notices and communications specified herein to be given to
Certificateholders to Cede & Co. and shall have no further obligation to the
Certificate Owners.;

                  (c) to the extent that the provisions of this Section 3.9
conflict with any other provisions of these Standard Terms, the provisions of
this Section 3.9 shall control;

                  (d) the rights of the Certificate Owners shall be exercised
only through DTC and shall be limited to those established by law and agreements
between such Certificate Owners and DTC and/or DTC Participants. Unless and
until Definitive Certificates are issued pursuant to Section 3.11, DTC will make
book-entry transfers among DTC Participants and receive and transmit
distributions of principal of and periodic distributions on the Certificates to
such DTC Participants, pursuant to the Letter of Representations; and

                  (e) whenever the Series Trust Agreement requires or permits
actions to be taken based upon instructions or directions of Certificateholders
evidencing a specified percentage, Cede & Co. shall be deemed to represent such
percentage only to the extent that it has received instructions to such

effect from Certificate Owners and/or DTC Participants owning or representing,
respectively, such required percentage and has delivered such instructions to
the Trustee.

                  SECTION 3.10 Legend on Global Certificates. Each global
Certificate shall bear the following legend:

                           This Certificate is a global Certificate within the
                           meaning of the Series Trust Agreement hereinafter
                           referred to and is registered in the name of the
                           Depository Trust Company ("DTC") or a nominee of DTC.
                           This Certificate is exchangeable for Certificates
                           registered in the name of a Person other than DTC or
                           its nominee only in the limited circumstances
                           described in the Series Trust Agreement and may not
                           be transferred except as a whole by DTC or by a
                           nominee of DTC to DTC or another nominee of DTC.

                           Unless this Certificate is presented by an authorized
                           representative of DTC to the Trust or its agent for
                           registration of transfer, exchange, or payment, and
                           any Certificate issued is registered in the name of
                           Cede & Co. or in such other name as is requested by
                           an authorized representative of DTC (and any payment
                           is made to Cede & Co. or to such other entity as is
                           requested by an authorized representative of DTC).
                           ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE
                           OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch
                           as the registered owner hereof, Cede & Co., has an
                           interest herein.

                  SECTION 3.11 Definitive Certificates. If (a) the Depositor
advises the Trustee in writing that DTC is no longer willing or able to properly
discharge its responsibilities with respect to the Certificates, and the
Depositor does not appoint a qualified successor within 90 days; (b) the
Depositor advises the Trustee in writing that it elects to terminate the
book-entry system through DTC; or (c) an Available Information Event occurs
(provided that the financial statements and other information about the
Underlying Securities Issuer referred to in Section 4.1(a)(iv) hereof are not
thereafter available to the Trust), then, in any such case, the Trustee shall
notify DTC of the occurrence of any such event and of its intent to make
Definitive Certificates available to Certificate Owners (or, in the case of an
event referred to in clause (c), the relevant event), and shall request the
surrender by DTC to the Trustee of the typewritten global Certificate or
Certificates representing the Book-Entry Certificates by DTC and the Trustee.
Upon such surrender, accompanied by registration instructions from DTC, the
Trustee shall execute and authenticate the Definitive Certificates in accordance
with the instructions of DTC. Neither the Certificate Registrar nor the Trustee
shall be liable for any delay in delivery of such instructions and each may
conclusively rely on, and shall be protected in relying on, such instructions.
Upon the issuance of Definitive Certificates, the Trustee shall recognize the
holders of the Definitive Certificates as Certificateholders.

                  SECTION 3.12 Depositor as Certificateholder. Subject to the
proviso set forth in the definition of "Outstanding" in Section 1.1, the
Depositor in its individual or any other capacity may become the owner or
pledgee of Certificates and may otherwise deal with the Trustee or its
Affiliates as if it were not the Depositor.

                  SECTION 3.13 Transfer Restrictions.

                  (a) No Certificateholder or Certificate Owner may, in any
transaction or series of transactions, directly or indirectly (each of the

all or any part of its interest in any Certificate issued to it, whether by act,
deed, merger

or otherwise, or (ii) mortgage, pledge or create a lien or security interest in
such beneficial interest unless such transfer satisfies the conditions set forth
in this Section 3.13. No purported transfer of any interest in any Certificate
or Book-Entry Certificate or any portion thereof which is not made in accordance
with this Section 3.13 shall be given effect by or be binding upon the Trust,
the Depositor or the Trustee and any such purported transfer shall be null and
void ab initio and vest in the transferee no rights against the Trust, the
Depositor or the Trustee.

                  By its acceptance of a Certificate or Book-Entry Certificate,
each Certificateholder or Certificate Owner will be deemed to have represented
and agreed that transfer thereof is restricted and agrees that it shall transfer
such Certificate or Book-Entry Certificate only in accordance with the terms of
the Series Trust Agreement and such Certificate or Book-Entry Certificate and in
compliance with applicable law.

                  (b) Unless otherwise specified in the Forepart, no
Certificates or Book-Entry Certificates may be transferred to a Benefit Plan or
any Person acting on behalf of a Benefit Plan.

                  SECTION 3.14 Deemed ERISA Plan Representation. Each purchaser
of a Certificate will be deemed to have represented, agreed and acknowledged, as
applicable, for the benefit of the Depositor and the Underwriters and their
respective Affiliates, that the purchaser is not a Benefit Plan or a Person
acting on behalf of a Benefit Plan.

                  SECTION 3.15 Actions by Certificateholders. No
Certificateholder may institute any Proceeding with respect to the Series Trust
Agreement unless (a) such Certificateholder previously has given to the Trustee

Trustee), on the Closing Date, the Depositor shall furnish to the Trustee an
Opinion of Counsel either stating that, in the opinion of such counsel, such
action has been taken with respect to the recording and filing of the Series
Trust Agreement, any agreements supplemental hereto and any other requisite
documents, and with respect to the execution and filing of any financing

Trust Agreement and reciting the details of such action, or stating that, in the
opinion of such counsel, no such action is necessary to make such lien and
security interest effective.

                  (d) If and only if the Forepart provides for the pledge of the
Underlying Securities or any other Trust Assets to the Trustee (and not merely
the transfer, assignment, conveyance and sale, without recourse, thereof to the
Trustee), at least annually after the Closing Date, the Depositor shall furnish
to the Trustee an Opinion of Counsel either stating that, in the opinion of such
counsel, such action has been taken with respect to the recording, filing,
re-recording and refiling of the Series Trust Agreement, any agreements
supplemental hereto and any other requisite documents, and with respect to the

         the proposed release will not impair the security under the Series
         Trust Agreement in contravention of the provisions hereof;

                  (ii) whenever any property or securities are to be released
         from the lien created by the Series Trust Agreement, if the fair value
         of the property or securities and of all other property or securities
         released from the lien created by the Series Trust Agreement since the

         10% or more of the Certificate Principal Balance of the Outstanding
         Certificates at the beginning of such year, then the Depositor shall
         furnish to the Trustee an Independent Certificate as to the fair value
         of the property or securities proposed to be released and stating that
         in the opinion of such person the proposed release will not impair the
         security under the Series Trust Agreement in contravention of the

         less than $25,000 or less than one percent of the then aggregate
         Certificate Principal Balance of the Outstanding Certificates;

                  (iii) prior to the deposit with the Trustee of any securities
         (other than Certificates or securities secured by a lien prior to the
         lien created by the Series Trust Agreement) in exchange for which the
         Trust is to authenticate and deliver Certificates, withdraw cash
         constituting a part of the Trust Assets or release of any property or

         the Depositor shall furnish to the Trustee an Officer's Certificate of
         the Depositor (within 90 days of such deposit), that meets the
         requirements of TIA Section 314(d) certifying or stating the opinion of
         each person signing such certificate as to the fair value to the
         Depositor of the securities to be so deposited;

                  (iv) whenever the Depositor is required to furnish to the
         Trustee an Officer's Certificate of the Depositor described in clause
         (iii) above, the Depositor shall also deliver to the Trustee an
         Independent Certificate as to the same matters, and in the case of
         authentication and delivery of Certificates, shall cover the fair value
         to the Depositor of all other securities so deposited since the then
         current calendar year as to which an Independent Certificate has not
         yet been furnished, if the fair value to the Depositor of the
         securities to be so deposited and of all other such securities made the
         basis of any such authentication and delivery, withdrawal or release
         since the commencement of the then current calendar year, as set forth
         in the certificates delivered pursuant to clause (iii) above and this
         clause (iv), is 10% or more of the Certificate Principal Balance of the
         Outstanding Certificates, but such a certificate need not be furnished
         with respect to any securities so deposited, if the fair value thereof
         to the Depositor as set forth in the related Officer's Certificate of
         the depositor is less than $25,000 or less than one percent of the
         aggregate Certificate Principal Balance of the Outstanding
         Certificates;

                  (v) subject to the payment of its fees and expenses hereunder,
         the Trustee may, and when required by the provisions of the Series
         Trust Agreement, shall, execute instruments to release property from
         the lien created by the Series Trust Agreement, or convey the Trustee's
         interest in the same, in a manner and under circumstances that are
         consistent with the provisions of the Series Trust Agreement. No party
         relying upon an instrument executed by the Trustee in connection
         therewith shall be bound to ascertain the Trustee's authority, inquire
         into the satisfaction of any conditions precedent or see to the
         application of any moneys; and

                  (vi) the Trustee shall at such time as there are no
         Outstanding Certificates and all sums due to the Trustee hereunder have
         been paid, release any remaining portion of the Trust Assets that
         secured the Certificates from the lien created by the Series Trust
         Agreement and release to the Depositor or any other Person entitled
         thereto any funds then included in the trust estate.

                  (a) The Trustee, for the benefit of the Certificateholders
shall establish and maintain in the name of the Trust, one Eligible Trust
Account known as the Collection Account, bearing an additional designation
clearly indicating that the funds deposited therein are held for the benefit of
the Certificateholders, subject to the obligations of the Trust under the Swap
Agreement, any Related Agreement and any Credit Enhancement Agreement. The
Trustee, directly or through its agents, shall make reasonable efforts to
collect all scheduled payments under the Trust Assets, the Swap Agreement, any
Related Agreement and any Credit Enhancement Agreement and will follow, or cause

under the sole dominion and control of the Trustee for the benefit of the
Certificateholders, subject to the obligations of the Trust under the Swap
Agreement, any Related Agreement and any Credit Enhancement Agreement. If, at

Trustee shall within 10 Business Days (or such longer period, not to exceed 30
calendar days, to which each Rating Agency may consent) establish a new
Collection Account as an Eligible Trust Account and shall transfer any funds in
the existing Collection Account to such new Collection Account.

                  (c) The Collection Account shall be a non-interest bearing
account. Pending application pursuant to Sections 6.2 or 8.2 hereof, moneys held
in the Collection Account shall not be reinvested except as provided in the
Forepart.

                  (a) Except to the extent otherwise specified in the Forepart,
the Trustee shall credit to the Collection Account all moneys or property
received by the Trust in respect of (i) the Trust Assets and (ii) payments to
the Trust under the Swap Agreements or the Related Agreements, other than any
payment made to the Trust on the Closing Date, which payment is required to be
applied to the purchase of the Trust Assets and (iii) any payments to the Trust
under any Credit Enhancement Agreement.

                  (b) On each Obligations Payment Date, the Trustee shall (i)
withdraw from the Collection Account such amounts as are necessary to satisfy
the expenses of the Trust, to the extent not paid by the Depositor pursuant to
Section 7.10 hereof, (ii) withdraw from the Collection Account and remit first
to the Swap Counterparty, then to the counterparty to any Related Agreement, and
then to the counterparty to any Credit Enhancement Agreement (in accordance with
any priority of payments specified in the Forepart), any amounts due to such
Person from the Trust on such date pursuant to the terms of the Swap Agreement,
the relevant Related Agreement or the relevant Credit Enhancement Agreement (net
of amounts due to the Trust from such Person on such date), and (iii) retain in
the Collection Account any amounts due to the Trust and received from such
Person on such date pursuant to the terms of the Swap Agreement, the relevant
Related Agreement or the relevant Credit Enhancement Agreement.

                  (c) On each Distribution Date, the Trustee shall, after paying
any amounts due under the Swap Agreement, any Related Agreement or any Credit
Enhancement Agreement as provided in Section 6.2(b), distribute from the
Collection Account to the Certificateholders, on a pro rata basis, all amounts
then remaining on deposit in the Collection Account, provided that any payments
which the Trustee has received in respect of the Swap Agreement, any Related
Agreement or any Credit Enhancement Agreement by 3:00 p.m. (New York City time)
on the Distribution Date will be distributed on the Distribution Date, and any
payments received after 3:00 p.m. on the Distribution Date will be distributed
on the next Business Day, and such delayed payments shall not include any
additional interest.

                  (d) The Trustee shall be entitled to rely on a certificate of
the Calculation Agent, if applicable, for the amount of any payments to be paid
or received by the Trust under the Swap Agreement, any Related Agreement or
Credit Enhancement Agreement or paid by the Trust on the Certificates, which the
Calculation Agent shall provide at least two (2) Business Days prior to each
Obligations Payment Date and Distribution Date, respectively.

                  (e) Notwithstanding the foregoing Sections 6.2(a) to (d), in
the event of an event described in Section 8.2(a) hereof, funds shall be applied
by the Trustee in accordance with Section 8.2 and not this Section 6.2.

(or allocations of income) to a Certificateholder such tax shall reduce the
amount otherwise distributable to the Certificateholder in accordance with this
Section 6.2, including any amounts payable to Certificateholders pursuant to
Section 8.2 below. The Trustee is hereby authorized and directed to retain from
amounts otherwise distributable to the Certificateholders sufficient funds for
the payment of any tax that is legally required to be withheld by the Trust (but
such authorization shall not prevent the Trustee if indemnified to its
satisfaction, from contesting any such tax in appropriate proceedings and
withholding payment of such tax, if permitted by law, pending the outcome of
such proceedings). The amount of any withholding tax imposed with respect to a
Certificateholder shall be treated as cash distributed to such Certificateholder
at the time it is withheld by the Trust and remitted to the appropriate taxing
authority. If there is a possibility that withholding tax is payable with
respect to a distribution (such as a distribution to a Certificateholder that is
a non-U.S. Person), the Trustee may in its sole discretion withhold such amounts
in accordance with this Section 6.2(f). If a Certificateholder wishes to apply
for a refund of any such withholding tax, the Trustee shall reasonably cooperate
with such Certificateholder in making such claim so long as such
Certificateholder agrees to reimburse the Trustee for any out-of-pocket expenses
incurred. The Trustee shall not be liable to any Person for withholding or
failing to withhold any such withholding tax.

                  (g) If the Trustee has received any amount from any Person in
respect of distributions of interest on the Underlying Securities or any other
Trust Asset and such Person is entitled to require and requires, that the
Trustee repay such amounts, the Trustee shall have the right to reimbursement of
any such amounts, from the Certificateholders with respect to any such amounts
distributed to Certificateholders and shall, to the extent provided under the
Swap Agreement, any Related Agreement or any Credit Enhancement Agreement, seek
reimbursement of any such amounts from the relevant party under such agreement,
including in each case any amounts payable to Certificateholders pursuant to
Section 8.2 below.

                  (h) Notwithstanding any other provisions in the Series Trust
Agreement, the right of any Certificateholder to receive payment of principal of
and interest on a Certificate on or after their due dates, and to institute suit
for the enforcement of any such payment on or after the date such payment is
payable, shall not be impaired without the consent of such Certificateholder.

                  SECTION 6.3 Appointment of Paying Agent. The Trustee may
appoint one or more paying agents (each, a "Paying Agent") with respect to the
Certificates. Any such Paying Agent shall be authorized to make distributions to
Certificateholders from the Collection Account pursuant to the provisions of the
Series Trust Agreement and shall report the amounts of such distributions to the
Trustee. Any Paying Agent shall have the revocable power to withdraw funds from
such Collection Account for the purpose of making such distributions. The
Trustee in its sole discretion, may revoke such power and remove the Paying
Agent. The Paying Agent shall initially be the Trustee and any co-paying agent
chosen by the Depositor and acceptable to the Trustee, including, if and so long
as any series of Certificates is listed on the any securities exchange and such
exchange so requires, a co-paying agent in any city required by the rules of
such exchange. Any Paying Agent shall be permitted to resign as Paying Agent
upon 30 days' notice to the Trustee. In the event that the Trustee shall resign
as Paying Agent, the Trustee shall appoint a successor or additional Paying
Agent. The Trustee shall cause each successor or additional Paying Agent to
execute and deliver to the Trustee an instrument in which such successor or
additional Paying Agent shall agree with the Trustee that (a) it will hold all
sums, if any, held by it for distribution to the Certificateholders in trust for
the benefit of the Certificateholders entitled thereto until such sums shall be
distributed to such Certificateholders or returned to the Trustee, and (b) it
will give the Trustee notice of any default, that is known to it, by any
Underlying Securities Issuer or the obligor under any other Trust Asset, the
Swap Agreement, any Related Agreement or any Credit Enhancement Agreement. The
Paying Agent shall return all unclaimed funds to the Trustee and upon removal
shall

also return all funds in its possession to the Trustee. The provisions of
Sections 7.1, 7.3, 7.8 and 7.10 shall apply to the Trustee also in its roles as
Paying Agent, for so long as the Trustee shall act as Paying Agent. Any
reference in the Series Trust Agreement to the Paying Agent shall include any
co-paying agent unless the context requires otherwise. Notwithstanding anything
contained herein to the contrary, the appointment of a Paying Agent pursuant to
this Section 6.3 shall not release the Trustee from the duties, obligations,
responsibilities or liabilities arising under the Series Trust Agreement other
than with respect to funds paid to such Paying Agent.

                  SECTION 6.4 Method of Payment. Subject to subsection 8.1(c),
distributions required to be made to Certificateholders on any Distribution Date
shall be made to each Certificateholder of record on the immediately preceding
Record Date either by wire transfer, in immediately available funds, to the
account of such Certificateholder at a bank or other entity having appropriate
facilities therefor, if such Certificateholder shall have provided to the
Certificate Registrar appropriate written instructions at least five Business
Days prior to such Record Date, or, if not, by check mailed to such
Certificateholder at the address of such Certificateholder appearing in the
Certificate Register.

                  SECTION 6.5 Reports to Certificateholders. On the next
Business Day following each Distribution Date, or as soon after each
Distribution Date as practicable, the Trustee shall forward or cause to be
forwarded to the Depositor, each Certificateholder and any other Persons
specified in the Forepart, a statement setting forth:

                  (a) the amount of the distribution on such Distribution Date
to Certificateholders of each Class allocable to principal of and premium, if
any, and interest on the Certificates of each such Class, and the amount of
aggregate unpaid interest accrued or accreted as of such Distribution Date;

                  (b) in the case of each Class of Certificates that bears
interest at a floating rate, the respective floating pass-through rate
applicable to each such Class on such Distribution Date, as calculated in
accordance with the method specified in such Certificates and the Series Trust
Agreement;

                  (c) the amount of compensation received by the Trustee for the
period relating to such Distribution Date and such other customary information
as the Trustee deems necessary or desirable, or that any such Certificateholder
reasonably requests, to enable such Certificateholders to prepare their tax
returns;

                  (d) the aggregate stated principal amount of the Underlying
Securities, the current rating assigned by each Rating Agency thereto and the
current interest rate (or weighted average interest rate) thereon at the close
of business on such Distribution Date;

                  (e) the aggregate Certificate Principal Balance of each Class
of Certificates, including any Class of Certificates not offered to the public)
at the close of business on such Distribution Date, separately identifying any
reduction in the aggregate Certificate Principal Balance due to the allocation
of any realized losses or otherwise; and

                  (f) as to any Class to which any Credit Enhancement Agreement
applies, the amount of credit support available under such agreement as of the
close of business on that Distribution Date.

                  In the case of information furnished pursuant to subclauses
(a) and (c) above, the amounts shall be expressed as a dollar amount (or the
equivalent thereof in any other specified currency) per minimum authorized
denomination of Certificates. Within a reasonable period of time after the end
of each calendar year, the Trustee shall furnish to each person who at any time
during such calendar year was a Certificateholder a statement containing the
information set forth in subclauses (a) and (c) above,

aggregated for such calendar year or the applicable portion thereof during which
such person was a Certificateholder. Such obligation of the Trustee shall be
deemed to have been satisfied to the extent that substantially comparable
information shall be provided by the Trustee pursuant to any requirements of the
Code as are from time to time in effect. In the case of the rating furnished
pursuant to subclause (d) above, the Trustee may rely on an information agent
such as Bloomberg L.P.

                  SECTION 6.6 Accounting and Information to Certificateholders,
Internal Revenue Service and Others. The Trustee shall (a) maintain (or cause to
be maintained) the books of the Trust on a calendar year basis on the accrual
method of accounting, (b) deliver to each Certificateholder, as may be required
by the Code and applicable Treasury Regulations or otherwise, such information
reasonably available to the Trustee as may be required to enable each
Certificateholder to prepare its federal income tax returns, (c) if the Trust is
intended to be treated as a grantor trust, as specified in the Forepart, file
such tax returns relating to the Trust and make such elections as may from time
to time be required or appropriate under any applicable state or federal statute
or rule or regulation thereunder, (d) cause such tax returns to be signed in the
manner required by law and (e) collect or cause to be collected any withholding
tax as described in and in accordance with subsection 6.2(f) with respect to
income or distributions to Certificateholders. The Trustee shall be authorized
to retain an agent for the purpose of performing its obligations under the
preceding clauses (a), (b) and (c), and any expense of any such agent, to the
extent not paid by the Depositor pursuant to its separate fee agreement with the
Trustee, shall be an expense of the Trust and not of the Trustee.

                  SECTION 6.7 Signature on Returns. The Trustee shall sign on
behalf of the Trust any and all tax returns of the Trust.

                                   ARTICLE VII
                                   THE TRUSTEE

                  SECTION 7.1 Duties of Trustee; Notice of Defaults.

                  (a) The Trustee shall not (except during the continuance of an
Event of Default) be liable except for the performance by the Trustee of such
duties, and only such duties, as are specifically set forth in the Series Trust
Agreement and the other Basic Documents, including the administration of the
Trust in the interest of the Certificateholders, subject to the Basic Documents
and in accordance with the provisions of the Series Trust Agreement. No implied
covenants or obligations shall be read into the Series Trust Agreement against
the Trustee or the Depositor. During the period that an Event of Default shall
have occurred and is continuing, the Trustee shall exercise such of the rights
and powers vested in it by the Series Trust Agreement, and shall use the same
degree of care and skill in their exercise, as a prudent person would exercise
or use under the circumstances in the conduct of such person's own affairs.

                  (b) In the absence of bad faith on its part, and except during
the continuance of an Event of Default, the Trustee may conclusively rely upon
certificates or opinions furnished to the Trustee and conforming to the
requirements of the Series Trust Agreement in determining the truth of the
statements and the correctness of the opinions contained therein; provided,
however, that the Trustee shall have examined such certificates or opinions so
as to determine compliance of the same with the requirements of the Series Trust
Agreement.

                  (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own willful
misfeasance, except that:

                  (i) this subsection 7.1(c) shall not limit the effect of
         subsections 7.1(a) or (b);

                  (ii) the Trustee shall not be liable for any error of judgment
         made in good faith by a Responsible Officer or Officers, or any
         Authorized Signatory, unless it is proved that the Trustee or such
         Authorized Signatory was negligent in ascertaining the pertinent facts;

                  (iii) the Trustee shall not be liable with respect to any
         action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Section 5.2, 5.3 or 7.5; and

                  (iv) the Trustee shall not be liable for any loss or
         diminution in value of Underlying Securities or other Trust Assets sold
         by it under the Series Trust Agreement in good faith in accordance with
         its terms.

                  (d) Subject to Section 6.1 and the definition of "Eligible
Trust Account" in Section 1.1 hereof, moneys received by the Trustee hereunder
need not be segregated in any manner except to the extent required by law and
may be deposited under such general conditions as may be prescribed by law, and
the Trustee shall not be liable for any interest thereon.

                  (e) The Trustee shall not take any action that (i) is
inconsistent with the purposes of the Trust set forth in Section 2.3, (ii)
would, to the actual knowledge of a Responsible Officer, or to the actual
knowledge of an Authorized Signatory in the case of any action taken by an or
Authorized Signatory, of the Trustee, result in the Trust's becoming taxable as
a corporation for federal income tax purposes, or (iii) the Trustee should
reasonably be expected to know would result in the Trust becoming taxable as a
corporation for federal income tax purposes (in this connection, the Trustee
shall be protected in assuming that the performance of its express duties
hereunder would not have such a result). The Depositor shall not direct the
Trustee to take any action that would violate the provisions of this Section
7.1.

                  (f) The Trustee shall have the legal power to exercise all of
the rights, powers and privileges of holders of the Underlying Securities and
other Trust Assets and all rights of the Trust under the Swap Agreement, any
Related Agreements and Credit Enhancement Agreements. However, neither the
Trustee (except as specifically provided herein) nor the Depositor shall be
under any obligation whatsoever to appear in, prosecute or defend any action,
suit or other proceeding in respect of the Underlying Securities or other Trust
Assets, the Swap Agreement or any Related Agreement or any Credit Enhancement
Agreement or the Certificates which is not incidental to its responsibilities
under the Series Trust Agreement or which in its opinion may involve it in any
expense or liability.

                  (g) If there is an event of default (as defined in the
indenture or other document pursuant to which the Underlying Securities were
issued) with respect to any Underlying Security and such default is known to the
Trustee, the Trustee shall give notice to DTC or, if any Certificates are
Definitive Certificates, directly to the relevant Certificateholders in the
manner and to the extent provided in TIA Section 313(c) within 90 days after
such event of default occurs. Such notice shall set forth (i) the identity of
the Underlying Securities, (ii) the date and nature of such event of default,
(iii) the face amount of the obligation to which such event of default relates,
(iv) the identifying numbers of the series of Certificates, or any combination,
as the case may be, evidencing the obligations (or portions thereof) described
above in clause (iii), and (v) any other information which the Trustee may deem
appropriate. Except in the case of a default in payment of principal or interest
in respect of the Underlying Securities or other Trust Assets, the Trustee shall
be protected in withholding the notice to Certificateholders if and so long as a
committee of its Responsible Officers in good faith determines that withholding
the notice is in the interests of the Certificateholders.

                  (h) If (i) default is made in the payment of any installment
of interest on any Underlying Security when the same becomes due and payable,
and such default continues unremedied for

the period specified in the indenture or other authorizing document for such
Underlying Security (or, if no such period is specified, five (5) days) after
receipt by the Underlying Securities Issuer of notice thereof from the Trustee
or receipt by the Underlying Securities Issuer and the Trustee of notice thereof
from Certificateholders representing at least 25% of the Certificate Principal
Balance; or (ii) default is made in the payment of the principal of or any
installment of the principal of any Underlying Security when the same becomes
due and payable, and such default continues unremedied for the period specified
in the indenture or other authorizing document for such Underlying Security (or,
if no such period is specified, five (5) days after receipt by the Underlying
Securities Issuer of notice thereof from the Trustee or receipt by the
Underlying Securities Issuer and the Trustee of notice thereof from
Certificateholders representing at least 25% of the Certificate Principal
Balance, and the Underlying Securities Issuer shall, upon demand of the Trustee,
fail to pay forthwith to the Trustee, for the benefit of the Certificateholders,
the whole amount then due and payable on such Underlying Security for principal
and interest, with interest upon the overdue principal, at the rate borne by the
Underlying Security and in addition thereto such further amount as shall be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee and
its agents and counsel, to the extent permitted by law and the terms of the
Underlying Securities, then (A) if the Underlying Securities are not covered by
a Credit Enhancement Agreement in favor of the Trust, the Trustee shall follow,
or cause to be followed, normal and customary practices and procedures as it
deems necessary or advisable to recover upon the defaulted Underlying
Securities, provided however, that the Trustee shall not be required to expend
or risk its own funds or otherwise incur personal financial liability, or (B) if
the Underlying Securities are covered by a Credit Enhancement Agreement, the
Trustee, subject to provision being made for indemnification against costs,
expenses and liabilities in a form satisfactory to the Trustee, shall institute
a Proceeding for the collection of the sums so due and unpaid, and shall
prosecute such Proceeding to judgment or final decree or settlement, and shall
enforce the same against the Underlying Securities Issuer or other obligor upon
the Underlying Securities and collect in the manner provided by law out of the
property of the Underlying Securities Issuer or other obligor upon the
Underlying Security wherever situated, the moneys adjudged or decreed to be
payable, unless otherwise directed by the Certificateholders evidencing a
majority of the Certificate Principal Balance. In connection therewith, the
Trustee shall use its best reasonable efforts in accordance with such normal and
customary practices as it shall deem necessary or advisable, and shall have the
power and authority, acting alone, to do any and all things in connection
therewith and the administration of the Trust as it may deem necessary or
advisable.

                  (i) Section 315(e) of the TIA is hereby excluded from
operation in respect of the Series Trust Agreement.

                  SECTION 7.2 Rights of Trustee. The Trustee is authorized and
directed to execute and deliver the Basic Documents and each certificate or
other document attached as an exhibit to or contemplated by the Basic Documents
to which the Trust is to be a party, in such written form as the Depositor shall
approve in writing, executed by a Responsible Officer. In addition to the
foregoing, the Trustee is authorized and shall be obligated to take all actions
required of the Trust pursuant to the Basic Documents.

                  SECTION 7.3 Acceptance of Trusts and Duties. Except as
otherwise provided in this Article VII, in accepting the trusts hereby created,
the Trustee acts solely as Trustee hereunder and not in its individual capacity
and all Persons having any claim against the Trustee by reason of the
transactions contemplated by the Series Trust Agreement or any Basic Document
shall look only to the Trust Assets for payment or satisfaction thereof. The
Trustee accepts the trusts hereby created and agrees to perform its duties
hereunder with respect to such trusts but only upon the terms of the Series
Trust Agreement. The Trustee also agrees to disburse all moneys actually
received by it constituting part of the Trust Assets upon the terms of the Basic
Documents. The Trustee shall not be liable or accountable under any Basic
Document under any circumstances, except (i) for its own negligent action, its
own negligent failure to act

or its own willful misfeasance or bad faith (except that the foregoing shall not
limit the effect of subsections 7.1(a) or (b), or (ii) in the case of the
inaccuracy of any representation or warranty contained in Section 7.7. In
particular, but not by way of limitation (and subject to the exceptions set
forth in the preceding sentence):

                  (a) the Trustee shall at no time have any responsibility or
liability for or with respect to the legality, validity and enforceability of
any Underlying Security, other Trust Asset, the Swap Agreement, any Related
Agreement and any Credit Enhancement Agreement, or the perfection and priority
of any security interest created by any Underlying Security or the maintenance
of any such perfection and priority, or for or with respect to the sufficiency
of the Trust Assets or their sufficiency to generate the payments to be
distributed to Certificateholders under the Series Trust Agreement, including,
without limitation: the terms and conditions of any Underlying Security, other
Trust Asset, the Swap Agreement, any Related Agreement and any Credit
Enhancement Agreement; the validity of the assignment of any Underlying Security
or other Trust Asset to the Trust or of any intervening assignment; the
completeness of any Underlying Security, other Trust Asset, the Swap Agreement,
any Related Agreement and any Credit Enhancement Agreement; the performance or
enforcement of any Underlying Security, other Trust Asset, the Swap Agreement,
any Related Agreement and any Credit Enhancement Agreement; the compliance by
the Depositor with any warranty or representation made under any Basic Document
or in any related document or the accuracy of any such warranty or
representation or any action of the Depositor taken in the name of the Trustee;

                  (b) under no circumstances shall the Trustee be liable for
indebtedness or other payment or distribution obligations evidenced by or
arising under any of the Basic Documents, including the Certificate Principal
Balance of and periodic distributions on the Certificates;

                  (c) the Trustee shall not be responsible for or in respect of
and makes no representation as to the validity or sufficiency of any provision
of the Series Trust Agreement, the accuracy or completeness of any offering
documents for the Certificates or for the due execution hereof by the Depositor
or for the form, character, genuineness, sufficiency, value or validity of any
of the Underlying Securities, the Certificates (other than the certificate of
authentication on the Certificates) or of any Underlying Securities or any
related documents, and the Trustee shall in no event assume or incur any
liability, duty or obligation to any Certificateholder, other than as expressly
provided for in the Basic Documents;

                  (d) the Trustee shall not be liable for the default or
misconduct of the Depositor or any other party (other than itself, as provided
in the Series Trust Agreement) under any of the Basic Documents or otherwise;

                  (e) the Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by the Series Trust Agreement or to make
any investigation of related matters or to institute, conduct or defend any
litigation under or in relation to the Series Trust Agreement at the request,
order or direction of any of the Certificateholders, unless the
Certificateholders have offered the Trustee reasonable security or indemnity
against the costs, expenses and liabilities which may be incurred by the
Trustee. The right of the Trustee to perform any discretionary act enumerated in
the Series Trust Agreement or in any other Basic Document shall not be construed
as a duty, and the Trustee shall not be answerable for other than its willful
misfeasance, bad faith or negligence in the performance of any such act or by
reason of reckless disregard of the Trustee's obligations and duties under the
Series Trust Agreement; and

                  (f) the Trustee shall not incur any liability to any
Certificateholder if, by reason of any provision of any present or future law,
or regulation thereunder, or any governmental authority, or by

reason of any act of God or war or other circumstance beyond the control of the
relevant party, the Trustee shall be prevented or forbidden from doing or
performing any act or thing which the terms of the Series Trust Agreement
provide shall be done or performed; and the Trustee shall not incur any
liability to any Certificateholder by reason of any non-performance or delay,
caused as aforesaid, in the performance of any act or thing which the terms of
the Series Trust Agreement provide shall or may be done or performed, or by
reason of any exercise of, or failure to exercise, any discretion provided for
in the Series Trust Agreement.

                  SECTION 7.4 Preferential Collection of Claims Against Trustee.
The Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent required by TIA
Section 311(a).

                  SECTION 7.5 Action upon Instruction by Certificateholders.

                  (a) Subject to Sections 5.2, 5.3 and 9.2(b) and in accordance
with the terms of the Basic Documents, the Certificateholders of a Class may by
written instruction direct the Trustee in the management of the Trust, or
consent to the waiver of any past default and its consequences, and may direct
the time, method and place of conducting any proceeding for any remedy available
to the Trustee or exercising any power given to the Trustee. Subject to Sections
7.3(e), 7.5(c) and 7.15, such direction may be exercised at any time by written
instruction of the Certificateholders pursuant to Section 5.3.

                  (b) Notwithstanding the foregoing, the Trustee shall not be
required to take any action under any Basic Document if the Trustee shall have
reasonably determined, or shall have been advised by counsel, that such action
is likely to result in liability on the part of the Trustee or is contrary to
the terms of any Basic Document or is otherwise contrary to law or the Series
Trust Agreement, or if the Trustee shall not have received indemnity
satisfactory to it as provided in Section 7.3(e). No provision of any Basic
Document shall require the Trustee to expend or risk funds or otherwise incur
any financial liability in the performance of any of its rights or powers under
any Basic Document, if the Trustee shall have reasonable grounds for believing
that repayment of such funds or adequate indemnity against such risk or
liability is not reasonably assured or provided to it.

                  (c) Whenever the Trustee is unable to decide between
alternative courses of action permitted or required by the terms of any Basic
Document, or is unsure as to the application, intent, interpretation or meaning
of any provision of the Series Trust Agreement or the other Basic Documents, the
Trustee shall promptly give notice (in such form as shall be appropriate under
the circumstances) to the Certificateholders requesting instruction as to the
course of action to be adopted, and, to the extent the Trustee acts in good
faith in accordance with any instruction received in accordance with Sections
5.2 and 5.3, or otherwise in accordance with the instructions of the Depositor
or the Certificateholders in accordance with the Series Trust Agreement, the
Trustee shall not be liable on account of such action to any Person. If the
Trustee shall not have received appropriate instructions within ten days of such
notice (or within such shorter period of time as reasonably may be specified in
such notice or may be necessary under the circumstances) it may, but shall be
under no duty to, take or refrain from taking such action which is consistent,
in its view, with the Series Trust Agreement or the other Basic Documents, and
as it shall deem to be in the best interests of the Certificateholders, and the
Trustee shall have no liability to any Person for any such action or inaction.

                  SECTION 7.6 Furnishing of Documents; Reports to
Certificateholders and DTC.

                  (a) The Trustee shall furnish to the Certificateholders,
promptly upon receipt of a written request therefor, duplicates or copies of all
reports, notices, requests, demands, certificates,

financial statements and any other instruments furnished to the Trustee under
the Basic Documents. In addition, if required by TIA Section 313(a), within 60
days after December 31 of each year, the Trustee shall mail to (i) each
Certificateholder as required by TIA Section 313(c) and (ii) the Depositor, a
brief report dated as of such date that complies with TIA Section 313(a). A copy
of any report delivered pursuant to this Section 7.6(a) shall, at the time of
its mailing to Certificateholders and the Depositor, be filed by the Trustee
with the Commission and each stock exchange, if any, on which the Certificates
are listed. The Depositor shall notify the Trustee if and when the Certificates
are listed on any stock exchange.

                  (b) The Trustee shall within 90 days of an event described in
TIA Section 313(b) mail to (i) each Certificateholder as required by TIA Section
313(c) and (ii) the Depositor, a brief report dated as of such date that
complies with TIA Section 313(b). A copy of any report delivered pursuant to
this Section 7.6(b) shall, at the time of its mailing to Certificateholders and
the Depositor, be filed by the Trustee with the Commission and each stock
exchange, if any, on which the Certificates are listed. The Depositor shall
notify the Trustee if and when the Certificates are listed on any stock
exchange.

                  (c) So long as the Certificates are held in DTC's book-entry
only system, annual unaudited reports setting forth the amounts of payments on
the Certificates, and whether such amounts are principal or interest shall be
prepared by the Trustee and sent to DTC. To the extent the Depositor fails to
provide the Trustee with a copy of any report referred to in Section 4.1(a)(i)
or (iv) herein prior to the 10th Business Day preceding the applicable filing
date therefor as required by such provisions, the Trustee shall request the
Depositor to prepare and file such report and, if the Depositor fails to do so,
shall cause such report to be prepared and filed and the Depositor shall
reimburse the Trustee for its reasonable expenses incurred in connection
therewith. Any such expenses not reimbursed by the Depositor shall be borne by
the Certificateholders.

                  SECTION 7.7 Representations and Warranties of Trustee. The
Trustee hereby represents and warrants to the Depositor, for the benefit of the
Certificateholders, that:

                  (a) it is a banking corporation duly incorporated, validly
existing and in good standing under the laws of the State of New York;

                  (b) it has full power, authority and legal right to execute,
deliver and perform the Series Trust Agreement and the other Basic Agreements,
and has taken all necessary action to authorize the execution, delivery and
performance by it of the Series Trust Agreement and the other Basic Agreements;

                  (c) the execution, delivery and performance by it of the
Series Trust Agreement (i) will not violate any provision of any law or
regulation governing the powers of the Trustee or any order, writ, judgment or
decree of any court, arbitrator or governmental authority applicable to the
Trustee or any of its assets and (ii) will not violate any provision of the
corporate charter or by-laws of the Trustee;

                  (d) the Series Trust Agreement has been duly executed and
delivered by the Trustee and constitutes the legal, valid and binding agreement
of the Trustee, enforceable in accordance with its terms, except as
enforceability may be limited by bankruptcy, insolvency, reorganization, or
other similar laws affecting the enforcement of creditors' rights in general and
by general principles of equity, regardless of whether such enforceability is
considered in a proceeding in equity or at law; and

                  (e) the execution, delivery and performance by the Trustee of
the Series Trust Agreement will not require the authorization, consent or
approval of, the giving of notice to, the filing or registration with, or the
taking of any other action in respect of, any governmental authority or agency

regulating the banking and corporate trust activities of banks or trust
companies in the jurisdiction in which the Trust was formed.

                  SECTION 7.8 Reliance; Advice of Counsel.

                  (a) The Trustee shall incur no liability to anyone in acting
upon any signature, instrument, notice, resolution, request, consent, order,
certificate, report, opinion, bond, facsimile transmission or other document or
paper reasonably believed by it to be genuine and reasonably believed by it to
be signed by the proper party or parties and need not investigate any fact or
matter in any such document. The Trustee may accept a certified copy of a
resolution of the board of directors or other governing body of any corporate
party as conclusive evidence that such resolution has been duly adopted by such
body and that the same is in full force and effect. As to any fact or matter the
method of the determination of which is not specifically prescribed herein, the
Trustee may for all purposes hereof rely on a certificate, signed by the
president or any vice president or by the treasurer or other authorized officers
of the relevant party, as to such fact or matter, and such certificate shall
constitute full protection to the Trustee for any action taken or omitted to be
taken by it in good faith in reliance thereon.

                  (b) In the exercise or administration of the trusts hereby
created and in the performance of its duties and obligations under the Series
Trust Agreement or the other Basic Documents, the Trustee: (i) may act directly
or through its agents, attorneys, custodians or nominees (including the granting
of a power of attorney to Responsible Officers or Authorized Signatories of the
Trustee to execute and deliver any Basic Documents, Certificate or other
documents related thereto on behalf of the Trustee) pursuant to agreements
entered into with any of them, and the Trustee shall not be liable for the
conduct or misconduct of such agents, attorneys, custodians or nominees if such
agents, attorneys, custodians or nominees shall have been selected by the
Trustee in good faith and with reasonable care and (ii) may consult with
counsel, accountants and other skilled professionals to be selected in good
faith and with reasonable care and employed by it. The Trustee shall not be
liable for anything done, suffered or omitted in good faith by it in accordance
with the opinion or advice of any such accountants or other such persons and not
contrary to the Series Trust Agreement or any other Basic Document.

                  SECTION 7.9 Trustee May Own Certificates. The Trustee in its
individual or any other capacity shall be permitted to become the owner or
pledgee of Certificates and may deal with the Depositor and the parties to the
Swap Agreement, any Related Agreement or any Credit Enhancement Agreement in
transactions in the same manner as it would have if it were not the Trustee,
subject to the limitations on the rights of the Trustee, if it is holding the
Certificates in its individual capacity, in voting on any demand, authorization,
direction, notice, consent or waiver hereunder, set forth in the definition of
"Outstanding" in Section 1.1 hereof.

                  SECTION 7.10 Compensation and Indemnity. The Trustee shall be
entitled to receive from the Depositor as compensation for the Trustee's
services hereunder, trustee's fees pursuant to a separate agreement between the
Trustee and the Depositor, and shall be reimbursed by the Depositor for all
reasonable expenses, disbursements and advances incurred or made by the Trustee
(including the reasonable compensation, disbursements and expenses of its
counsel and other persons not regularly in its employ). The Depositor shall
indemnify and hold harmless the Trustee and its successors, assigns, agents,
directors, officers and employees against any and all loss, liability or
reasonable expense (including attorney's fees) incurred by it in connection with
any legal action relating to the administration of this Trust and the
performance of its duties thereunder. The Trustee shall notify the Depositor
promptly of any claim for which it or any such Person may seek indemnity.
Failure by the Trustee to so notify the Depositor shall not relieve the
Depositor of its obligations hereunder except to the extent of any damages
caused by such delay. The Depositor need not reimburse any expense or indemnify
against any loss, liability or expense that is incurred by the Trustee through
the Trustee's own willful misfeasance,

negligence or bad faith in the performance of the Trustee's duties under the
Series Trust Agreement or as a result of a breach or by reason of reckless
disregard of the Trustee's obligations and duties under the Series Trust
Agreement. The indemnities contained in this Section 7.10 shall survive the
resignation or termination of the Trustee or the termination of the Series Trust
Agreement.

                  Failure by the Depositor to pay, reimburse or indemnify the
Trustee shall not entitle the Trustee to any payment, reimbursement or
indemnification from the Trust unless otherwise specified in the Forepart, nor
shall such failure release the Trustee from the duties it is required to perform
under the Series Trust Agreement. Any unpaid, unreimbursed or unindemnified
amounts shall not be borne by the Trust and shall not constitute a claim against
the Trust, but shall be borne by the Trustee in its individual capacity unless
it is specified that the Trustee is entitled to payment, reimbursement or
indemnification from the Trust, in which event such amounts will be paid in
accordance with the priority of payments set out in the Forepart.

                  SECTION 7.11 Replacement of Trustee.

                  (a) The Trustee may resign at any time and be discharged from
the trusts hereby created by giving 30 days' prior written notice thereof to the
Depositor. The Depositor may appoint a successor Trustee by delivering a written
instrument, in duplicate, to the resigning Trustee and the successor Trustee. If
no successor Trustee shall have been appointed and have accepted appointment
within 30 days after the giving of such notice of resignation, the resigning
Trustee may petition any court of competent jurisdiction for the appointment of
a successor Trustee. The Depositor shall remove the Trustee if:

                  (i)   the Trustee shall cease to be eligible in accordance
         with the provisions of Section 7.14 and shall fail to resign after
         written request therefor by the Depositor;

                  (ii)  the Trustee shall be adjudged bankrupt or insolvent;

                  (iii) a receiver or other public officer shall be appointed or
         take charge or control of the Trustee or of its property or affairs for
         the purpose of rehabilitation, conservation or liquidation; or

                  (iv)  the Trustee shall otherwise be incapable of acting.

                  (b) If the Trustee resigns or is removed or if a vacancy
exists in the office of Trustee for any reason, the Depositor shall promptly
appoint a successor Trustee by written instrument, in duplicate (one copy of
which instrument shall be delivered to the outgoing Trustee so removed and one
copy to the successor Trustee) and shall pay all fees and expenses owed to the
outgoing Trustee.

                  (c) Unless the Trust has been completely liquidated and the
proceeds of the liquidation distributed to Certificateholders, any resignation
or removal of the Trustee and appointment of a successor Trustee pursuant to any
of the provisions of this Section 7.11 shall not become effective until a
written acceptance of appointment is delivered by the successor Trustee to the
outgoing Trustee and the Depositor and all fees and expenses due to the outgoing
Trustee are paid; provided that with respect to any of the events specified in
Section 7.11(a), the payment of the fees and expenses due to the outgoing
Trustee shall not be a condition for the removal of such Trustee and the
appointment of a successor Trustee. Any successor Trustee appointed pursuant to
this Section 7.11 shall be eligible to act in such capacity in accordance with
Section 7.14 and, following compliance with the preceding sentence, shall become
fully vested with all the rights, powers, duties and obligations of its
predecessor under the Series Trust Agreement, with like effect as if originally
named as Trustee. The Depositor shall provide notice

                                                                     EXHIBIT 4.2


within five (5) Business Days of the resignation or removal of the Trustee to
each Rating Agency and each Certificateholder.

                  (d) The predecessor Trustee shall deliver to the successor
Trustee all documents and statements and moneys held by it under the Series
Trust Agreement. The Depositor and the predecessor Trustee shall execute and
deliver such instruments and do such other things as may reasonably be required
for fully and certainly vesting and confirming in the successor Trustee all such
rights, powers, duties and obligations.

                  (e) Upon acceptance of appointment by a successor Trustee
pursuant to this Section 7.11, the Depositor shall mail notice of the successor
of such Trustee to all Certificateholders and each Rating Agency.

                  SECTION 7.12 Merger or Consolidation of Trustee. Any
corporation into which the Trustee may be merged or converted or with which it
may be consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any corporation
succeeding to all or substantially all the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be eligible pursuant to Section 7.14, and without the
execution or filing of any instrument or any further act on the part of any of
the parties hereto; provided, however, that the Trustee shall mail notice of
such merger or consolidation to each Rating Agency.

                  SECTION 7.13 Appointment of Co-Trustee or Separate Trustee.

                  (a) Notwithstanding any other provisions of the Series Trust
Agreement, at any time, for the purpose of meeting any legal requirement of any
jurisdiction in which any part of the Trust Assets may at the time be located,
the Depositor and the Trustee acting jointly shall have the power and shall
execute and deliver all instruments to appoint one or more Persons approved by
the Trustee to act as co-trustee, jointly with the Trustee, or as separate
trustee or trustees, of all or any part of the Trust Assets, and to vest in such
Person in such capacity such title to the Trust Assets, or any part thereof,
and, subject to the other provisions of this Section 7.13, such powers, duties,
obligations, rights and trusts as the Depositor and the Trustee may consider
necessary or desirable. If the Depositor shall not have joined in such
appointment within fifteen (15) days after the receipt by it of a request so to
do, the Trustee alone shall have the power to make such appointment. No
co-trustee or separate trustee under the Series Trust Agreement shall be
required to meet the terms of eligibility as a successor trustee pursuant to
Section 7.14 and no notice of the appointment of any co-trustee or separate
trustee shall be required pursuant to Section 7.11.

                  (b) Each separate trustee and co-trustee shall, to the extent
permitted by law, be appointed and act subject to the following provisions and
conditions:

                  (i) all rights, power, duties and obligations conferred or
         imposed upon the Trustee shall be conferred upon and exercised or
         performed by the Trustee and such separate trustee or co-trustee
         jointly (it being understood that such separate trustee or co-trustee
         is not authorized to act separately without the Trustee joining in such
         act), except to the extent that under any law of any jurisdiction in
         which any particular act or acts are to be performed, the Trustee shall
         be incompetent or unqualified to perform such act or acts, in which
         event such rights, powers, duties and obligations (including the
         holding of title to the Trust Assets or any portion thereof in any such
         jurisdiction) shall be exercised and performed singly by such separate
         trustee or co-trustee, but solely at the direction of the Trustee;

                  (ii) no separate trustee or co-trustee under the Series Trust
         Agreement shall be personally liable by reason of any act or omission
         of any other trustee under the Series Trust Agreement; and

                  (iii) the Depositor and the Trustee acting jointly may at any
         time accept the resignation of, or may remove, any separate trustee or
         co-trustee.

                  (c) Any notice, request or other writing given to the Trustee
shall be deemed to have been given to each of the then separate trustees and
co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to the Series Trust
Agreement and the conditions of this Article. Each separate trustee and
co-trustee, upon its acceptance of the trusts conferred, shall be vested with
the estates or property specified in its instrument of appointment, either
jointly with the Trustee or separately, as may be provided therein, subject to
all the provisions of the Series Trust Agreement, specifically including every
provision of the Series Trust Agreement relating to the conduct of, affecting
the liability of, or affording protection to, the Trustee. Each such instrument
shall be filed with the Trustee and a copy thereof given to the Depositor.

                  (d) Any separate trustee or co-trustee may at any time appoint
the Trustee as its agent or attorney-in-fact with full power and authority, to
the extent not prohibited by law, to do any lawful act under or in respect of
the Series Trust Agreement on its behalf and in its name. If any separate
trustee or co-trustee shall die, become incapable of acting, resign or be
removed, all of its estates, properties, rights, remedies and trusts shall vest
in and be exercised by the Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.

                  SECTION 7.14 Eligibility Requirements for Trustee.

                  (a) The Trustee shall at all times satisfy the requirements of
TIA Section 310(a). The Trustee shall at all times be a bank, trust company or
corporation not an Affiliate of the Depositor (but may have normal banking
relationships with the Depositor or any Underlying Securities Issuer or any
party under the Swap Agreement, any Related Agreement or any Credit Enhancement
Agreement and their respective Affiliates), which (i) is organized and doing
business under the laws of any State or the United States; (ii) is authorized
under such laws to exercise corporate trust powers; (iii) has a combined capital
and surplus of at least $50,000,000; (iv) is subject to supervision or
examination by federal or state authority; and (v) has (or has a parent which
has) a long-term unsecured debt rating of at least BBB- by Standard & Poor's and
at least Baa3 by Moody's (or such other rating as may be specified in the
Forepart). If such corporation shall publish reports of condition at least
annually, pursuant to law or to the requirements of the aforesaid supervising or
examining authority, then for the purpose of this Section 7.14, the combined
capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section 7.14, the Trustee shall resign immediately
in the manner and with the effect specified in Section 7.11.

                  (b) The Trustee shall comply with TIA Section 310(b);
provided, that if the exclusion requirements set forth in TIA Section 310(b)(1)
are met, any other trust agreement under which other securities are outstanding
that evidence beneficial ownership interests in obligations of any Underlying
Securities Issuer shall be excluded from the operation of TIA Section 310(b)(1).

                  SECTION 7.15 Voting of the Underlying Securities.

                  (a) The Trustee shall exercise any voting or consent rights
with respect to the Underlying Securities as directed in writing by
Certificateholders holding Certificates representing at least


                                     - 34 -
<PAGE>   41
                                                                     EXHIBIT 4.2


a majority of the Outstanding Certificate Principal Balance. In the absence of
any written direction from such Certificateholders, the Trustee shall not
exercise any voting or consent rights with respect to the Underlying Securities.
Notwithstanding the foregoing, if the Trust is intended to qualify as a grantor
trust, the Trustee shall not exercise such rights if the exercise thereof (or
the action with respect to which such rights are so elicited) would cause the
Trust to fail to qualify as a grantor trust (or fail to have such other
qualification as may be specified in the Forepart). As a condition of exercising
any such rights, if the Trust is intended to qualify as a grantor trust, the
Trustee may require an opinion of counsel to the effect that exercising such
rights would not cause the Trust to fail to qualify as a grantor trust (or fail
to have such other qualification as may be specified in the Forepart).

                  (b) The Trustee may, subject to the provisions of Section
7.15(a), vote and give consents and waivers in respect of the Underlying
Securities as permitted by DTC and except as provided herein. In the event that
the Trustee receives a request from the Underlying Securities Issuer for its
consent to any amendment, modification or waiver of the Underlying Securities or
any document 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 Certificate Principal Balances) as the
Certificates were actually voted or not voted by the Certificateholders thereof
as of a date determined by the Trustee prior to the date on which such consent
or vote is required.

                  (c) Notwithstanding anything to the contrary herein, the
Trustee shall at no time vote or consent to any matter:

                  (i) unless such vote or consent (or the action with respect to
         which such vote or consent is solicited) would not, based on an opinion
         of counsel, alter the classification of the Trust as either a grantor
         trust, or such other classification as may be specified in the
         Forepart, for federal income tax purposes;

                  (ii) that would alter the timing or amount of any payment on
         the Trust Assets, including, without limitation, any demand to
         accelerate the Underlying Securities, except upon the occurrence of an
         Underlying Securities Event of Default, unless Certificateholders
         representing 100% of the aggregate Voting Rights of the Certificates
         consent to the Trustee voting in favor of or consenting to that matter;
         or

                  (iii) that 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 an Underlying Securities Event of Default, unless
         Certificateholders representing 100% of the aggregate Voting Rights of
         the Certificates consent to the Trustee voting in favor of or
         consenting to that matter.

                  The Trustee shall have no liability for any failure to act
resulting from any Certificateholder's late return of, or failure to return,
directions requested by the Trustee from the Certificateholders.

                  (d) 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 Underlying Securities, or any other offer is made for the
Underlying Securities, the Trustee shall notify the Certificateholders of such
offer as promptly as practicable. The

Trustee must reject any such offer unless (a) an Underlying Securities Event of
Default has occurred, (b) the Trustee is directed by the unanimous affirmative
vote of the Certificateholders to accept such offer and (c) the Trustee has
received an opinion of counsel to the effect that any such exchange will not (i)
alter the classification of the Trust as a grantor trust, or such other
classification as may be specified in the Forepart, for federal income tax
purposes and (ii) result in a deemed exchange of the Underlying Securities or
the Certificates for federal income tax purposes].

                  (e) If an Underlying Securities Event of Default occurs and is
continuing, and if directed by all the holders of the then Outstanding
Certificates, the Trustee shall, subject to the provisions of Section 7.15(a),
vote the Underlying Securities in favor of directing, or take such other action
as may be appropriate to direct, the trustee of the Underlying Securities to
declare the unpaid principal balance of the Underlying Securities plus accrued
and unpaid interest thereon to be due and payable.

                  SECTION 7.16 Annual Statement. The Trustee shall deliver to
the Depositor and the Trustee, for the benefit of the Certificateholders, an
annual statement signed by two officers of the Trustee to the effect that the
Trustee has fulfilled its obligations under the Series Trust Agreement
throughout the preceding year with respect to the Certificates. Copies of such
statement shall be furnished without charge to Certificateholders upon written
request to the Trustee at the address for notices to the Trustee specified
herein.

                            TERMINATION OF AGREEMENT

                  SECTION 8.1 Termination of Agreement.

                  (a) The Series Trust Agreement (other than Section 7.10) shall
terminate and the Trust shall dissolve, wind-up and terminate and be of no
further force or effect 60 days after the earlier of the (i) final distribution
by the Trustee of all moneys or other property or proceeds of the Trust Assets
in accordance with the terms of Article VI or Section 8.2 of the Series Trust
Agreement and (ii) the distribution by the Trustee in accordance with the terms
of Article VI or Section 8.2 of the Series Trust Agreement of the proceeds of
the purchase of all the Trust Assets by the party entitled to do so, under the
circumstances and in the manner described in the Forepart. The bankruptcy,
liquidation, dissolution, death or incapacity of any Certificateholder shall not
(A) operate to terminate the Series Trust Agreement or the Trust, (B) entitle
such Certificateholder's legal representatives or heirs to claim an accounting
or to take any action or proceeding in any court for a partition or winding up
of all or any part of the Trust or the Trust Assets or (C) otherwise affect the
rights, obligations and liabilities of the parties hereto.

                  (b) Neither the Depositor nor any Certificateholder shall be
entitled to revoke or terminate the Trust.

                  (c) Notice of any termination of the Trust, specifying the
Distribution Date upon which the Certificateholders shall surrender their
Certificates to the Trustee for payment of the final distribution and
cancellation, shall be given by the Trustee by letter to the Certificateholders
mailed in accordance with Section 10.3 below stating: (i) the Distribution Date
upon or with respect to which final payment of the Certificates shall be made
upon presentation and surrender of the Certificates at the office of the Trustee

Upon presentation and surrender of the Certificates, the Trustee shall cause to
be distributed to Certificateholders amounts distributable on such Distribution
Date pursuant to Section 6.2.

                  (d) If all of the Certificateholders shall not surrender their
Certificates for cancellation within six months after the date specified in the
above mentioned written notice, the Trustee shall give a second written notice
to the remaining Certificateholders to surrender their Certificates for

one year after the second notice all the Certificates shall not have been
surrendered for cancellation, the Trustee may take appropriate steps, or may
appoint an agent to take appropriate steps, to contact the remaining
Certificateholders concerning surrender of their Certificates, and the cost
thereof shall be paid out of the funds and other assets that shall remain
subject to the Series Trust Agreement. Subject to applicable laws with respect
to escheat of funds, any funds remaining in the Trust after exhaustion of such
remedies in the preceding sentence shall be deemed property of the Depositor and
distributed by the Trustee to the Depositor, and the Certificateholders shall
have no claim against the Trustee or the Depositor with respect thereto.

upon the Trustee obtaining actual knowledge of any occurrence of a Trust
Liquidation Event, promptly give notice of such occurrence to the
Certificateholders.

                  (b) Upon the occurrence of a Trust Liquidation Event, the
Trustee shall cause the Trust Assets to be liquidated in the manner set forth in

Collection Account and the Trustee shall:

                  (i) (A) withdraw from the Collection Account such amounts as
         are necessary to satisfy the expenses of the Trust, to the extent not
         paid by the Depositor pursuant to Section 7.10 hereof, (B) withdraw
         from the Collection Account and remit first to the Swap Counterparty,
         then to the counterparty to any Related Agreement, and then to the
         counterparty to any Credit Enhancement Agreement (in accordance to any
         priority of payments specified in the Forepart), any amounts due to
         such Person from the Trust on such date pursuant to the terms of the
         Swap Agreement, the relevant Related Agreement or the relevant Credit
         Enhancement Agreement (net of amounts due to the Trust from such Person
         on such date), and (C) retain in the Collection Account any amounts due
         to the Trust and received from such Person on such date pursuant to the
         terms of the Swap Agreement, the relevant Related Agreement or the
         relevant Credit Enhancement Agreement.

                  (ii) after paying any amounts due under the Swap Agreement,
         any Related Agreement or any Credit Enhancement Agreement as provided
         in Section 8.2(b)(i) above, distribute from the Collection Account to
         the Certificateholders, on a pro rata basis, all amounts then remaining
         on deposit in the Collection Account, including any payments which the
         Trustee receives in respect of the Swap Agreement, any Related
         Agreement or any Credit Enhancement Agreement.

                  (c) The proceeds and the timing of the sale of the Trust
Assets by the Trustee shall be at the risk of the Swap Counterparty, the
counterparty to any Related Agreement or any Credit Enhancement Agreements and
the Certificateholders and without recourse to the Trustee, who shall execute
such sales based on advice obtained pursuant to Section 8.2(d) below and apply
the proceeds of the sale as set forth in Section 8.2(b).
