2003, the Trustee shall cause the Trust to pay to the Depositor the amount of
interest accrued and paid on the Underlying Securities from May 15, 2003, to
but not including the Closing Date; provided, however, that in the event an
Optional Exchange shall occur prior to the Distribution Date in November 2003,
a pro rata portion of such amount shall be paid to the Depositor on the
Optional Exchange Date in accordance with the provisions of Section 7(b)(ix)
hereof. If the Depositor is not paid any such amount on such date, it shall
have a claim for such amount. If Available Funds are insufficient to pay such
amount, the Trustee will pay the Depositor its pro rata share, based on the
ratio the amount owed to the Depositor bears to all amounts owed on the

                                      8

Certificates in respect of accrued interest, of any proceeds from the recovery
on the Underlying Securities.

          (d) The Depositor may sell to the Trustee additional Underlying
Securities on any date hereafter upon at least three Business Days' notice to
the Trustee (or such shorter period as shall be mutually satisfactory to the
Depositor and the Trustee) and upon (i) satisfaction of the Rating Agency
Condition and (ii) delivery of an Opinion of Counsel to the effect that the
sale of such additional Underlying Securities will not cause the Trust to be
taxed as an association or publicly traded partnership taxable as a
corporation for federal income tax purposes. Each condition to be satisfied
with respect to a sale of Underlying Securities on or prior to the Closing
Date shall be satisfied with respect to a sale of additional Underlying
Securities no later than the date of sale thereof, each representation and
warranty set forth in the Standard Terms to be made on the Closing Date shall
be made on such date of sale, and from and after such date of sale, all
Underlying Securities held by the Trustee shall be held on the same terms and
conditions. Upon such sale to the Trustee, the Trustee shall deposit such
additional Underlying Securities in the Certificate Account, and shall
authenticate and deliver to the Depositor, on its order, (x) Class A-1
Certificates and Class A-2 Certificates in the same proportion to the
additional Underlying Securities and to each other as exists with respect to
the original Class A-1 Certificates and Class A-2 Certificates, and (y) Call
Warrants related to such additional Class A-1 Certificates and Class A-2
Certificates as described herein. Any such additional Class A-1 Certificates
and Class A-2 Certificates authenticated and delivered shall have the same
terms and rank pari passu with the corresponding classes of Certificates
previously issued in accordance with this Series Supplement.

          (e) No Class A-2 Certificate may be offered, resold, assigned or
otherwise transferred (including by pledge or hypothecation) at any time prior
to (x) the date which is two years or such shorter period of time as permitted
by Rule 144(k) under the Securities Act, after the later of the original issue
date of such Class A-2 Certificates and the last date on which the Depositor
or any "affiliate" (as defined in Rule 144 under the Securities Act) of the
Depositor was the owner of such Class A-2 Certificates (or any predecessor
thereto), or (y) such later date, if any, as may be required by a change in
applicable securities laws (the "Resale Restriction Termination Date") unless
such offer, resale, assignment or transfer is (i) to the Trust, (ii) pursuant
to an effective registration statement under the Securities Act, (iii) to a
qualified institutional buyer (a "QIB"), as such term is defined in Rule 144A
promulgated under the Securities Act ("Rule 144A"), in accordance with Rule
144A or (iv) pursuant to another available exemption from registration
provided under the Securities Act (including transfers to Accredited
Investors), and, in each of cases (i) through (iv), in accordance with any
applicable securities laws of any state of the United States and other
jurisdictions. Prior to any offer, resale, assignment or transfer of any Class
A-2 Certificates in the manner described in clause (iii) above, the
prospective transferee and the prospective transferor shall be required to
deliver to the Trustee an executed copy of an Investment Letter with respect
to the Class A-2 Certificates to be transferred substantially in the form of
Exhibit C hereto and in the event the resale, assignment or transfer shall
involve Class A-2 Certificates then being held in physical form, such Class
A-2 Certificates shall be delivered to the Trustee for cancellation and the
Trustee shall instruct the Depository to increase the aggregate principal
amount of the Class A-2 Certificates held in book-entry form by an amount
equal to the aggregate principal amount of the Class A-2 Certificates so
resold, assigned or transferred and to issue a beneficial interest in such
global Class A-2

                                      9
<PAGE>

Certificates to such transferee. Prior to any offer, resale, assignment or
transfer of any Class A-2 Certificates in the manner described in
clause (iv) above, the prospective transferee and the prospective
transferor shall be required to deliver to the Trustee documentation
certifying that the offer, resale, assignment or transfer complies with the
provisions of said clause (iv) and, in the event any such Class A-2
Certificate shall then be held in book entry form and such resale, assignment
or transfer shall be to an Accredited Investor that is not a QIB, the Trustee
shall instruct the Depository to decrease the aggregate principal amount of
the Class A-2 Certificates held in book entry form and the Trustee shall
authenticate and deliver one or more Class A-2 Certificates in physical form
in an aggregate principal amount equal to the amount of Class A-2 Certificates
resold, assigned or transferred. In addition to the foregoing, each
prospective transferee of any Class A-2 Certificates in the manner
contemplated by clause (iii) above shall acknowledge, represent and agree as
follows:

         (1)      The transferee (x) is a QIB, (y) is aware that the
                  sale to it is being made in reliance on Rule 144A and (z) is
                  acquiring such Class A-2 Certificates for its own account or
                  for the account of a QIB.

         (2)      The transferee understands that the Class A-2
                  Certificates are being offered in a transaction not
                  involving any public offering in the United States within
                  the meaning of the Securities Act, and that the Class A-2
                  Certificates have not been and will not be registered under
                  the Securities Act.

         (3)      The transferee agrees that (A) if in the future it
                  decides to offer, resell, pledge or otherwise transfer the
                  Class A-2 Certificates prior to the Resale Restriction
                  Termination Date, such Class A-2 Certificates shall only be
                  offered, resold, assigned or otherwise transferred (i) to
                  the Trust, (ii) pursuant to an effective registration
                  statement under the Securities Act, (iii) to a QIB, in
                  accordance with Rule 144A or (iv) pursuant to another
                  available exemption from registration provided under the
                  Securities Act (including any transfer to an Accredited
                  Investor), and, in each of cases (i) through (iv), in
                  accordance with any applicable securities laws of any state
                  of the United States and other jurisdictions and (B) the
                  transferee will, and each subsequent holder is required to,
                  notify any subsequent purchaser of such Class A-2
                  Certificates from it of the resale restrictions referred to
                  in clause (A) above.

          (f)     The Class A-2 Certificates will, unless otherwise agreed by
the Depositor and the Trustee, bear a legend substantially to the following
effect:

                  "THIS CLASS A-2 CERTIFICATE (OR ITS PREDECESSOR) HAS NOT
                  BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
                  AMENDED, AND MAY NOT BE TRANSFERRED, SOLD OR OTHERWISE
                  DISPOSED OF EXCEPT WHILE A REGISTRATION UNDER SUCH ACT IS IN
                  EFFECT OR PURSUANT TO AN EXEMPTION THEREFROM UNDER SUCH ACT.
                  THE CLASS A-2 CERTIFICATE REPRESENTED HEREBY MAY BE

                  NOTIFIED THAT THE SELLER OF THIS CLASS A-2 CERTIFICATE MAY
                  BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5
                  OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER."

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

          (a)  the Underlying Securities set forth on Schedule I hereto; and

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

          Section 5. Distributions.

          (a)  Except as otherwise provided in Sections 3(c), 5(b), 5(d), 5(g)
and 5(h) on each applicable Distribution Date (or such later date as specified
in Section 9(f)), the Trustee shall apply Available Funds in the Certificate
Account as follows:

               (i)   The Trustee will pay the interest portion of Available
          Funds:

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

                    (2) second, to the holders of the Class A-1 Certificates,
               as interest at the rate of 7.00% per annum on the outstanding
               Certificate Principal Balance of the Class A-1 Certificates.

               The Class A-2 Certificates are not entitled to distributions
of interest.

               (ii)  the Trustee will pay the principal portion of
          Available Funds:

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

                    (2) second, to the holders of the Class A-1 Certificates
               and the Class A-2 Certificates, the remaining available
               principal portion of Available Funds (in an aggregate amount
               not to exceed the outstanding Certificate Principal Balance of
               the Class A-1 Certificates and Class A-2 Certificates) pro rata
               in proportion to their outstanding Certificate Principal
               Balances.

                                      11
<PAGE>

                    (iii) any Available Funds remaining in the Certificate
               Account after the payments set forth in clauses 5(a)(i) and
               5(a)(ii) above shall be paid to the Trustee as reasonable
               compensation for services rendered to the Depositor, up to
               $1,000.

                    (iv) the Trustee will pay any Available Funds remaining in
               the Certificate Account after the distributions in clauses
               5(a)(i) through 5(a)(iii) above to the holders of the Class A-1
               Certificates and Class A-2 Certificates pro rata in proportion
               to their original Certificate Principal Balances.

Any funds received in respect of the Underlying Securities from the Underlying
Securities Guarantor shall be included in Available Funds on the related
Distribution Date or Special Distribution Date. Any portion of the Available
Funds (i) that does not constitute principal of, or interest on, the
Underlying Securities, (ii) that is not received in connection with a tender
offer, redemption, prepayment or liquidation of the Underlying Securities and
(iii) for which allocation by the Trustee is not otherwise contemplated by
this Series Supplement, shall be remitted by the Trustee to the Depositor.

          (b)  Notwithstanding the foregoing, if the Underlying Securities are
redeemed, prepaid or liquidated in whole or in part for any reason other than
due to the occurrence of an Event of Default, an SEC Reporting Failure, or the
Final Scheduled Distribution Date, the Trustee shall apply Available Funds in
the manner described in Section 5(g) in the following order of priority:

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

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

                  (iii) third, to the holders of the Class A-1 Certificates
               and Class A-2 Certificates, pro rata in proportion to their
               outstanding Certificate Principal Balances;

                   (iv) fourth, to the Trustee, as reasonable compensation
               for services rendered to the Depositor, any remainder up to
               $1,000; and

                    (v) fifth, to the holders of the Class A-1 Certificates
               and Class A-2 Certificates, any amount remaining after the
               distributions in clauses 5(b)(i) through 5(b)(iv) above, pro
               rata in proportion to their original Certificate Principal
               Balances.

          (c)  Notwithstanding the foregoing, if the Underlying Securities are
redeemed, prepaid or liquidated in whole or in part due to the occurrence of
an Event of Default, the Trustee shall distribute Available Funds to the
holders of the Class A-1 Certificates and holders of the Class A-2
Certificates in accordance with the ratio of the Class A-1 Allocation to the
Class A-2 Allocation.

          (d)  Unless otherwise instructed by holders of Certificates
representing a majority of the Voting Rights, thirty (30) days after giving
notice pursuant to Section 8 hereof, the Trustee shall sell the Underlying
Securities pursuant to Section 13 hereof and deposit the Liquidation

                                      12
<PAGE>

Proceeds, if any, into the Certificate Account for distribution not later than
two Business Days after the receipt of immediately available funds in accordance
with Section 5(b) hereof, provided, however, that if any Warrant Holder
designates any day on or prior to the proposed sale date as a Call Date and
Optional Exchange Date pursuant to Section 7, the portion of Underlying
Securities related to such Optional Exchange shall not be sold but shall be
distributed to the Warrant Holder pursuant to Section 7 and the Warrant Agent
Agreement.

          (e)  If the Trustee receives non-cash property in respect of the
Underlying Securities as a result of a payment default on the Underlying
Securities (including from the sale thereof), the Trustee will promptly give
notice to the Depository, or for any Certificates which are not then held by
DTC or any other depository, directly to the registered holders of the
Certificates then outstanding and unpaid and to the Warrant Agent. Such notice
shall state that the Trustee shall, and the Trustee shall, not later than 30
days after the receipt of such property, allocate and distribute such property
to the holders of Class A-1 Certificates and Class A-2 Certificates then
outstanding and unpaid, pro rata by outstanding Certificate Principal Balance
(after deducting the costs incurred in connection therewith) in accordance
with Section 5(b) hereof. Property other than cash will be liquidated by the
Trustee, and the proceeds thereof distributed in cash, only to the extent
necessary to avoid distribution of fractional securities to
Certificateholders. In-kind distribution of such property to
Certificateholders, based on the market value of such property as of the date
of distribution to Certificateholders, will be deemed to reduce the
Certificate Principal Balance of Certificates on a dollar-for-dollar basis.

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

          (g)  If a payment with respect to the Underlying Securities is made
to the Trustee (i) after the payment date of the Underlying Securities on
which such payment was due or (ii) after the Underlying Securities are
redeemed, prepaid or liquidated, in whole or in part, of the Underlying
Securities for any reason other than due to the occurrence of an Event of
Default, an SEC Reporting Failure or at their maturity, then the Trustee will
distribute any such amounts received in accordance with the provisions of this
Section 5 on the next occurring Business Day (a "Special Distribution Date")
as if the funds had constituted Available Funds on the Distribution Date
immediately preceding such Special Distribution Date; provided, however, that
the Record Date for such Special Distribution Date shall be one Business Day
prior to the day on which the related payment was received with respect to the
Underlying Securities.

          (h)  Notwithstanding Section 3.12 of the Standard Terms, upon the
occurrence of an SEC Reporting Failure, the Depositor shall instruct the
Trustee within a reasonable time to (i) notify the Warrant Agent that the
Underlying Securities are proposed to be sold and that any Call Warrants and
related Optional Exchange rights must be exercised no later than the date
specified in the notice (which shall be not less than 10 Business Days after
the date of such notice) and (ii) to the extent that the Warrant Holders fail
to exercise their Call Warrants and related Optional Exchange rights on or
prior to such date, to sell the Underlying Securities and distribute the
proceeds of such sale to the Certificateholders in accordance with the
following order of priority:

                                      13
<PAGE>

first, to the Trustee, as reimbursement for any Extraordinary Trust Expenses
incurred by the Trustee in accordance with Section 6(b) below and approved by
100% of the Certificateholders; and second, any remainder to the holders of the
Class A-1 Certificates and the Class A-2 Certificates pro rata in proportion
to the ratio of the Class A-1 Allocation to the Class A-2 Allocation, as
determined by the Calculation Agent.

          (i) (i) If the Trustee receives notice of a tender offer for some or
all of the Underlying Securities, the Trustee shall, within one Business Day,
notify the Warrant Agent and forward to the Warrant Agent copies of all
materials received by the Trustee in connection therewith. Upon the
commencement of a tender offer from the Underlying Securities Issuer or an
affiliate thereof and if the Trustee receives a Call Notice from any Warrant
Holder no later than five Business Days prior to the expiration of the tender
offer acceptance period that such Warrant Holder desires to exercise all or a
portion of its Call Warrants in connection with the consummation of any such
tender offer, then the Trustee shall tender, in compliance with the tender
offer requirements, an amount of Underlying Securities equal to the amount of
Underlying Securities that would be distributable to the Warrant Holder with
respect to an Optional Exchange of the Called Certificates called by such
Warrant Holder; provided that any Optional Call or Optional Exchange
undertaken in connection with any such tender offer shall be subject to the
provisions of Section 7 hereof.

              (ii) The Call Date and Optional Exchange Date for any exercise of
     Call Warrants in connection with a tender offer shall be deemed to be the
     Business Day on which such Underlying Securities are accepted for payment
     and paid for.

             (iii) The Call Price shall be deducted from the tender offer
     proceeds and paid to the holders of the Class A-1 Certificates and Class
     A-2 Certificates pro rata in accordance with the provisions of Section
     7(d)(v), and the excess of the tender offer proceeds over the Call Price
     shall be paid to the exercising Warrant Holders pro rata in respect to
     their proportionate exercises of Call Warrants or, if the Call Price
     exceeds the tender offer proceeds the amount of such excess shall be paid
     by the exercising Warrant Holders pro rata in respect to their
     proportionate exercises of Call Warrants.

            (iv)   If fewer than all tendered Underlying Securities are accepted
     for payment and paid for, (A) the amount of Call Warrants exercised shall
     be reduced to an amount that corresponds to a number of Class A-1 and
     Class A-2 Certificates that could be exchanged in an Optional Exchange
     for the Underlying Securities accepted for payment and paid for (without
     regard to any restrictions on the amount to be exchanged, so long as such
     restrictions would have been satisfied had all tendered Underlying
     Securities been accepted for payment and paid for); (B) each Warrant
     Holder's exercise shall be reduced by its share (proportionate to the
     amount specified in its exercise notice) of the amount of Underlying
     Securities not accepted for payment and paid for; (C) the Call Price
     shall be determined after giving effect to the reduction specified in
     clause (B); (D) the Call Warrants that relate to the reduction specified
     in clause (B) shall remain outstanding; and (E) the excess of the tender
     offer proceeds over the Call Price shall be allocated in proportion to
     the amount of Call Warrants deemed exercised as set forth in clause (A)
     above or, if the Call Price exceeds the tender offer proceeds the amount
     of such excess

                                      14
<PAGE>

     shall be paid by the exercising Warrant Holders pro rata
     in respect to their proportionate exercises of Call Warrants.

          (v)     If the tender offer is terminated by the Underlying Securities
     Issuer or any other tender offeror without consummation thereof or if all
     tenders by the Trust of Underlying Securities are otherwise rejected,
     then (1) the Call Notices will be of no further force and effect, and (2)
     any Call Warrants relating to such Call Notices will not be exercised and
     will remain outstanding.

          (j) (i) Within five Business Days (or such longer period as shall be
acceptable to the Trustee) of receipt of notice of an SEC Reporting Failure,
any Class A-1 Certificateholder or Class A-2 Certificateholder may direct the
Trustee to distribute all or a portion of such Certificateholder's pro rata
share of the Underlying Securities to it, in lieu of any proceeds received
upon liquidation of the Underlying Securities. The respective pro rata shares
of the Class A-1 and Class A-2 Certificateholders in the Underlying Securities
shall be determined by allocating the portion of the principal amount
remaining after reimbursement of the Trustee for any Extraordinary Trust
Expenses approved by 100% of the Certificateholders to the Class A-1
Certificateholders and the Class A-2 Certificateholders in accordance with the
ratio of the Class A-1 Allocation to the Class A-2 Allocation. The pro rata
share of each of the Certificateholders in the Underlying Securities to be
distributed shall be determined based on the then unpaid Certificate Principal
Balances of their Certificates.

          (ii)    Within five Business Days (or such longer period as shall be
     acceptable to the Trustee) of receipt of notice of an Event of Default or
     any other liquidation of the Underlying Securities by the Trustee, any
     Class A-2 Certificateholder may direct the Trustee to distribute all or a
     portion of such Class A-2 Certificateholder's pro rata share (as
     determined by the Calculation Agent in accordance with this Section 5(j))
     of the Underlying Securities to it, in lieu of any proceeds received upon
     liquidation of the Underlying Securities. Upon the occurrence of an Event
     of Default, each Class A-2 Certificateholder's pro rata share of the
     Underlying Securities shall be determined by allocating the principal
     amount of the Underlying Securities to the Class A-1 Certificateholders
     and the Class A-2 Certificateholders in accordance with the ratio of the
     Class A-1 Allocation to the Class A-2 Allocation. The pro rata share of
     each of the Class A-2 Certificateholders in the Underlying Securities to
     be distributed shall be determined based on the then outstanding
     Certificate Principal Balance of their respective Certificates. In the
     event of a liquidation of the Underlying Securities by the Trustee for
     any reason other than upon the occurrence of an Event of Default or an
     SEC Reporting Failure, each Class A-2 Certificateholder's pro rata share
     of the Underlying Securities shall be equal to a pro rata share (based on
     the proportion of the aggregate Certificate Principal Balance of such
     holder's Class A-2 Certificates to the outstanding aggregate Certificate
     Principal Balance of the Class A-2 Certificates) of the principal amount
     of Underlying Securities remaining after the Trustee has allocated
     Available Funds in accordance with Sections 5(b)(i) and 5(b)(ii) hereof.

          (iii)   The amount requested to be distributed pursuant to Section
     5(j)(i) or 5(j)(ii) must be in an even multiple of the minimum
     denomination of the Underlying Securities and may not exceed such
     requesting Certificateholder's pro rata share (as

                                      15
<PAGE>

     determined by the Calculation Agent in accordance with this Section
     5(j)) of the Underlying Securities. Upon receipt of any such direction
     from a Class A-1 Certificateholder or Class A-2 Certificateholder, the
     Trustee shall not liquidate the requested portion of Underlying
     Securities and instead shall cause such Underlying Securities to be
     distributed to the requesting Class A-1 Certificateholder or Class A-2
     Certificateholder; provided, that the Trustee shall not cause the
     distribution of any Underlying Securities to any Class A-1
     Certificateholder or Class A-2 Certificateholder unless, but for the
     requesting Class A-1 Certificateholder or Class A-2 Certificateholder's
     giving direction in accordance with this Section 5(j), such Underlying
     Securities would be liquidated as otherwise provided in this Agreement.
     Any portion of any Class A-1 Certificateholder's or Class A-2
     Certificateholder's pro rata share of the Underlying Securities that is
     not distributed, based on the failure to meet the minimum denomination
     requirements or otherwise, shall be sold in accordance with the
     provisions of Section 5(d) or 5(h) hereof, as applicable and the proceeds
     thereof distributed to such Class A-1 Certificateholder or Class A-2
     Certificateholder.

          (iv)    All decisions and determinations of the Calculation Agent
     pursuant to this Section 5(j) shall be in its sole discretion and shall,
     in the absence of manifest error, be conclusive for all purposes and
     irrevocably binding upon the Certificateholders.

          Section 6.  Trustee's Fees.

          (a)  As compensation for its services hereunder, the Trustee shall be
entitled to the Trustee Fee and any amounts payable under clauses 5(a)(iii)
and (5)(b)(iv) above. The Trustee Fee shall be paid by the Depositor and not
from Trust Property. The Trustee shall bear all Ordinary Expenses. Failure by
the Depositor to pay such amount shall not entitle the Trustee to any payment
or reimbursement from the Trust, nor shall such failure release the Trustee
from the duties it is required to perform under the Trust Agreement.

          (b)  Extraordinary Expenses shall not be paid out of the Trust
Property unless all the holders of the Class A-1 Certificates and Class A-2
Certificates then outstanding have directed the Trustee to incur such
Extraordinary Expenses. The Trustee may incur other Extraordinary Expenses if
any lesser percentage of the Certificateholders requesting such action
pursuant hereto reimburse the Trustee for the cost thereof from their own
funds in advance. If Extraordinary Expenses are not approved unanimously as
set forth in the first sentence of this Section 6(b), such Extraordinary
Expenses shall not be an obligation of the Trust, and the Trustee shall not
file any claim against the Trust therefor notwithstanding failure of
Certificateholders to reimburse the Trustee.

          Section 7.  Optional Exchange; Optional Call.

          (a)  On any (i) Distribution Date, (ii) date on which a tender offer
for some or all of the Underlying Securities is consummated or (iii) date on
which the Underlying Securities are to be redeemed by the Underlying
Securities Issuer, any holder of Class A-1 Certificates, Class A-2
Certificates and the related Call Warrants, if Call Warrants related to such
Certificates are outstanding, may exchange such Certificates and, if
applicable, Call Warrants, for a distribution of Underlying Securities
representing the same percentage of the Underlying Securities as such

                                      16
<PAGE>

Certificates represent of all outstanding Certificates. On any Call Date, any
Warrant Holder may exchange Called Certificates for a distribution of
Underlying Securities representing the same percentage of Underlying
Securities as such Called Certificates represent of all outstanding
Certificates; provided that any such exchange shall either (x) result from an
exercise of all Call Warrants owned by such Warrant Holder or (y) occur on a
Call Date on which such Warrant Holder, alone or together with one or more
other Warrant Holders, shall exchange Called Certificates relating to
Underlying Securities having an aggregate principal amount equal to or in
excess of the product of (i) 0.1 and (ii) the aggregate principal amount of
the Underlying Securities deposited into the Trust on the Closing Date.

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

               (i)    A notice specifying the number of Certificates being
          surrendered and the Optional Exchange Date shall be delivered to the
          Trustee no less than 5 days (or such shorter period acceptable to
          the Trustee) but not more than 30 days before the Optional Exchange
          Date; provided that for an Optional Exchange to occur on a Call
          Date, unless otherwise specified therein, the Call Notice shall be
          deemed to be the notice required hereunder.

               (ii)   Certificates and, if applicable, the Call Warrants, shall
          be surrendered to the Trustee no later than 10:00 a.m. (New York
          City time) on the Optional Exchange Date; provided that for an
          Optional Exchange to occur on a Call Date, payment of the Call Price
          to the Warrant Agent pursuant to Section 1.1(a)(iii) of the Warrant
          Agent Agreement shall satisfy the requirement to surrender
          Certificates.

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

               (iv)   The Trustee shall have received an opinion of counsel
          stating that the Optional Exchange would not cause the Trust to be
          treated as an association or publicly traded partnership taxable as
          a corporation for federal income tax purposes.

               (v)    If the Certificateholder is the Depositor or any Affiliate
          of the Depositor, (1) the Trustee shall have received a
          certification from the Certificateholder that any Certificates being
          surrendered have been held for at least six months, and (2) the
          Certificates being surrendered may represent no more than 5% (or 25%
          in the case of Certificates acquired by the Underwriter but never
          distributed to investors) of the then outstanding Certificates.

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

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

                                      17
<PAGE>

          the Underlying Securities; provided that satisfaction of
          the conditions set forth in this Section 7(b) shall entitle the
          Certificateholder or Warrant Holder, as applicable, to a
          distribution thereof.

               (viii) The aggregate principal amount of Certificates exchanged
          in connection with any Optional Exchange pursuant to this Section
          shall be in an amount that will entitle the Certificateholders
          thereof to Underlying Securities in an even multiple of the minimum
          denomination of such Underlying Securities.

               (ix)   In the event such Optional Exchange shall occur prior to
          the Distribution Date in November 2003, the Certificateholders shall
          have paid to the Trustee, for distribution to the Depositor, on the
          Optional Exchange Date an amount equal to the sum obtained by
          multiplying the amount of accrued interest on the Underlying
          Securities from May 15, 2003 through, but excluding, the Closing
          Date by a fraction, the numerator of which shall be the Certificate
          Principal Balance of Certificates being exchanged on such Optional
          Exchange Date and the denominator of which shall be the total
          Certificate Principal Balance of Certificates.

          (c)  Concurrently with the execution of this Series Supplement, the
Trustee, on behalf of the Trust, shall execute the Warrant Agent Agreement and
the Call Warrants, dated as of the date hereof and substantially in the form
of Exhibit B hereto, initially evidencing all of the Call Warrants. The
Trustee shall perform the Trust's obligations under the Warrant Agent
Agreement and the Call Warrants in accordance with their respective terms.

          (d)  Call Warrants may be exercised by the Warrant Holder, in whole
or in part, on any Call Date. In addition to the conditions set forth in
Section 1.1 of the Warrant Agent Agreement, the following conditions shall
apply to any Optional Call.

               (i)   The Warrant Holder shall have provided a certificate of
          solvency to the Trustee.

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

               (iii) Delivery of a Call Notice does not give rise to an
          obligation on the part of the Warrant Holder to pay the Call Price.
          If, by 10:00 a.m. (New York City time) on the Call Date, the Warrant
          Holder has not paid the Call Price (except in connection with a Call
          Notice relating to a tender offer for or redemption of the
          Underlying Securities), then the Call Notice shall automatically
          expire and none of the Warrant Holder, the Warrant Agent or the
          Trustee shall have any obligation with respect to the Call Notice.
          The expiration of a Call Notice shall in no way affect the Warrant
          Holder's right to deliver a Call Notice at a later date. The Call
          Price for a call in connection with a tender offer or redemption
          shall be deducted from the proceeds of a tender offer or redemption
          by the Trust pursuant to Section 5(i)(iii) and Section 7(d)(v), as
          applicable.

               (iv)  Subject to receipt of the Call Price, the Trustee shall
          pay the applicable portion of the Call Price to the Class A-1 and
          Class A-2 Certificateholders on the Call

                                      18
<PAGE>

          Date. The Call Price for each Class of Certificates in respect
          of partial calls shall be allocated pro rata to the
          Certificateholders of such Class.

               (v)   The Trustee shall not consent to any amendment or
          modification of this Agreement (including the Standard Terms) which
          would adversely affect the Warrant Holders (including, without
          limitation, any alteration of the timing or amount of any payment of
          the Call Price or any other provision of this Agreement in a manner
          adverse to the Warrant Holders) without the prior written consent of
          100% of the Warrant Holders. For purposes of this clause, no
          amendment, modification or supplement required to provide for any
          purchase by the Trustee of additional Underlying Securities and
          authentication and delivery by the Trustee of additional
          Certificates and Call Warrants pursuant to Section 3(d) shall be
          deemed to adversely affect the Warrant Holders.

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

          (e)  This Section 7 shall not provide the Warrant Holder with a lien
against, an interest in or a right to specific performance with respect to the
Underlying Securities; provided that satisfaction of the conditions set forth
in Section 7(b) shall entitle the Certificateholder or Warrant Holder, as
applicable, to a distribution of the Underlying Securities.

          (f)  The rights of the Certificateholders under the Trust Agreement
and the Certificates are limited by the terms, provisions and conditions of
the Trust Agreement, the Warrant Agent Agreement and the Call Warrants with
respect to the exercise of the Call Warrants by the Warrant Holder. The
Certificateholders, by their acceptance of Certificates, covenant and agree to
tender any and all Called Certificates to the Trustee upon the Warrant
Holder's exercise of Call Warrants and payment of the Call Price for such
Certificates in accordance with the provisions hereof and of the Warrant Agent
Agreement.

          (g) (i)  If the Trustee receives notice of a redemption by the
Underlying Securities Issuer for some or all of the Underlying Securities, the
Trustee shall, within three Business Days, notify the Warrant Agent and
forward to the Warrant Agent copies of all materials received by the Trustee
in connection therewith. Any Warrant Holder that desires to call Underlying
Securities in connection with a redemption by the Underlying Securities Issuer
shall send a Call Notice to the Trustee no later than seven Business Days
prior to the date such Underlying Securities are to be redeemed.

               (ii)   The Call Date and Optional Exchange Date for any exercise
          of Call Warrants in connection with a redemption by the Underlying
          Securities Issuer shall be deemed to be the Business Day on which
          such Underlying Securities are redeemed by the Underlying Securities
          Issuer.

               (iii)  The Call Price shall be deducted from the redemption
          proceeds and paid to the holders of the Class A-1 Certificates and
          Class A-2 Certificates pro rata in accordance with the provisions of
          Section 7(d)(v), and the excess of the redemption

                                      19
<PAGE>

          proceeds over the Call Price shall be paid to the exercising
          Warrant Holders pro rata in respect to their proportionate exercises
          of Call Warrants.

               (iv)   If fewer than all Underlying Securities are redeemed by
          the Underlying Securities Issuer and the amount of Call Warrants
          exercised corresponds to a number of Class A-1 and Class A-2
          Certificates that could be exchanged in an Optional Exchange for a
          principal amount of Underlying Securities that exceeds the principal
          amount of Underlying Securities actually redeemed, then, unless
          otherwise directed by any exercising Warrant Holder, (A) the amount
          of Call Warrants exercised shall be reduced to an amount that
          corresponds to a number of Class A-1 and Class A-2 Certificates that
          could be exchanged in an Optional Exchange for the principal amount
          of Underlying Securities redeemed by the Underlying Securities
          Issuer (without regard to any restrictions on the amount to be
          exchanged); (B) each Warrant Holder's exercise shall be reduced by
          its share (proportionate to the amount specified in its exercise
          notice) of the amount of such excess; (C) the Call Price shall be
          determined after giving effect to the reduction specified in clause
          (B); (D) the Call Warrants that relate to the reduction specified in
          clause (B) shall remain outstanding; and (E) the excess of the
          redemption proceeds over the Call Price shall be allocated in
          proportion to the amount of Call Warrants deemed exercised as set
          forth in clause (A) above.

               (v)   If the Underlying Securities are not redeemed by the
          Underlying Securities Issuer for any reason, then (1) the Call
          Notices will be of no further force and effect, and (2) any Call
          Warrants relating to such Call Notices will not be exercised and
          will remain outstanding.

          Section 8.  Notices of Events of Default.

                  As promptly as practicable after, and in any event within 30
days after, the occurrence of any Event of Default actually known to the
Trustee, the Trustee shall give notice of such Event of Default to the
Depository, or, if any Certificates are not then held by DTC or any other
depository, directly to the registered holders of such Certificates and to the
Warrant Agent. However, except in the case of an Event of Default relating to
the payment of principal of or interest on any of the Underlying Securities,
the Trustee will be protected in withholding such notice if in good faith it
determines that the withholding of such notice is in the interest of the
Certificateholders.

          Section 9.  Miscellaneous.

          (a)  The provisions of Section 4.04, Advances, of the Standard Terms
shall not apply to the Sprint Capital Note-Backed Series 2003-17 Certificates.

Certificateholders pursuant to Section 4.03 of the Standard Terms and to the
New York Stock Exchange.

shall not be entitled to terminate the Trust or cause the sale or other

not apply to the Sprint Capital Note-Backed Series 2003-17 Certificates.

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

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

          (h)  The Trust may not engage in any business or activities other
than in connection with, or relating to, the holding, protecting and
preserving of the Trust Property and the issuance of the Certificates and the
Call Warrants, and other than those required or authorized by the Trust
Agreement or incidental and necessary to accomplish such activities. The Trust
may not issue or sell any certificates or other obligations other than the
Certificates and the Call Warrants or otherwise incur, assume or guarantee any
indebtedness for money borrowed. Notwithstanding Section 3.05 of the Standard
Terms, funds on deposit in the Certificate Account shall not be invested.
Section 2.01(f) of the Standard Terms shall be superseded by this provision.

          (i)  Notwithstanding anything in the Trust Agreement to the contrary,
the Trustee may be removed upon 60 days prior written notice delivered by the
holders of Class A-1 Certificates and Class A-2 Certificates representing the
Required Percentage-Removal.

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

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

          (l)  In relation to Section 7.01(f) of the Standard Terms, any
periodic reports filed by the Trustee pursuant to the Exchange Act in
accordance with the customary practices of the Depositor, need not contain any
independent reports.

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

                                      21

obtaining actual knowledge of the occurrence of a Defeasance (as defined in
the Indenture) with respect to the Underlying Securities.

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

          (p)  All directions, demands and notices hereunder or under the
Standard Terms shall be in writing and shall be delivered as set forth below

          (r)  The provisions of Section 2.01(d)(iii) of the Standard Terms
shall not apply to the Sprint Capital Note-Backed Series 2003-17 Certificates
and the following shall be deemed to be inserted in its place:

               "at the time of delivery of the Underlying Securities, the
               Depositor owns such Underlying Securities, has the right to
               transfer its interest in such Underlying Securities and such
               Underlying Securities are free and clear of any lien,
               pledge, encumbrance, right, charge, claim or other security
               interest; and"

          (s)  A Plan (as herein defined) fiduciary, whether or not a
Certificateholder at such time, may request in writing that the Trustee
provide such Plan fiduciary with such information as shall be necessary for it
to determine whether any of the Call Warrant holders is (i) a "party in
interest" (within the meaning of ERISA, Section 3(14)); or (ii) a
"disqualified person" within the meaning of Internal Revenue Code ("Code")
Section 4975(e)(2) with respect to any employee benefit plan or Plan
identified to the Trustee by such Plan fiduciary at the time such request is
made in order for the Plan fiduciary to determine whether an investment in the
Certificates by such Plan is or would be permissible under ERISA or the Code.
Any such written request of a Plan fiduciary shall be accompanied by a
certification of the Plan fiduciary, opinion of counsel experienced in such
issues, and such other documentation as the Trustee may require, in order to
establish that such disclosure is necessary for the Plan fiduciary to
determine compliance with ERISA and the Code, as well as a confidentiality
agreement, whereby the Plan fiduciary agrees not to disclose the identity of
any Call Warrant holders except to any legal or other experts as necessary to
make such determination. The holder of a Call Warrant shall upon reasonable
request of the Trustee, in order for the Trustee to satisfy its obligations to
a Plan fiduciary, provide the Trustee with any one or more of the following,
in the sole discretion of the Call Warrant holder: (i) a certificate that each
of the Call Warrant holders is not (x) a "party in interest" (within the
meaning of ERISA, Section 3(14)) with respect to any "employee benefit plan"
as defined in ERISA, Section 3(3); or (y) a "disqualified person" within the
meaning of Internal Revenue Code Section 4975(e)(2) with respect to a "Plan"
as defined in Code Section 4975(e)(1) except in each case with respect to
plans sponsored by the Call Warrant holder or its affiliates which cover
employees of the Call Warrant holder and/or such affiliates; (ii) a

                                      23
<PAGE>

certificate that each of the Call Warrant holders is not such a "party in
interest" or "disqualified person" with respect to any employee benefit plan
or Plan identified to the Trustee by such Plan fiduciary at the time such
request is made; or (iii) a written consent to the limited disclosure of the
respective Call Warrant holder's identity to a specific Plan fiduciary solely
for purposes of allowing the Trustee to satisfy its obligations to a Plan
fiduciary.

          (t)  The Trustee shall appoint a firm of independent certified public
accountants to review each of the distribution reports prepared by the Trustee
pursuant to Section 4.03 of the Standard Terms and to verify (x) that such
reports and the calculations made therein were made accurately and in
accordance with the terms of the Trust Agreement and (y) that the Depositor
and the Trustee have each fulfilled their obligations under this Trust
Agreement. The Trustee shall instruct the accountants (i) to promptly report
to the Trustee any errors in such distribution reports discovered in verifying
such calculations and (ii) to render to the Trustee an annual examination
report, prepared in compliance with established or stated criteria as set
forth in the professional standards of the American Institute of Certified
Public Accountants, within 45 days (or such longer period as may be acceptable
to the Trustee) following the end of each calendar year that specifies the
calculations made in reviewing the distribution reports prepared by the
Trustee for the previous calendar year and such accountants' associated
findings.

          (u)  Each of the representations, covenants and agreements made
herein by each of the Depositor and the Trustee are for the benefit of the
Certificateholders and the Warrant Holders.

          Section 10.  Governing Law. THIS SERIES SUPPLEMENT AND THE
TRANSACTIONS DESCRIBED HEREIN SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS
MADE AND PERFORMED WITHIN THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO THE
CHOICE OF LAWS PROVISIONS THEREOF.

          Section 11.  Counterparts. This Series Supplement may be executed in
any number of counterparts, each of which shall be deemed to be an original,
and all such counterparts shall constitute but one and the same instrument.

          Section 12.  Termination of the Trust. The Trust shall terminate upon
the earliest to occur of (i) the payment in full at maturity or sale by the
Trust after a payment default, call or an acceleration or other early payment
of the Underlying Securities and the distribution in full of all amounts due
to the Class A-1 Certificateholders and Class A-2 Certificateholders; (ii) the
exercise of all outstanding Call Warrants by the Warrant Holder; (iii) the
final Distribution Date and (iv) the expiration of 21 years from the death of
the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador
of the United States to the Court of St. James, living on the date hereof.

          Section 13.  Sale of Underlying Securities; Optional Exchange. In the
event of a sale of the Underlying Securities pursuant to this Agreement or
pursuant to the instructions of the Warrant Agent under Section 1.2 of the
Warrant Agent Agreement, the Trustee shall solicit bids for the sale of the
Underlying Securities with settlement thereof on or before the third Business
Day after such sale from three leading dealers in the relevant market. Any of
the following dealers (or their successors) shall be deemed to qualify as
leading dealers: (1) Credit Suisse First

                                      24
<PAGE>

Boston LLC, (2) Goldman, Sachs & Co., (3) Merrill Lynch, Pierce,
Fenner & Smith Incorporated, (4) UBS Securities LLC, (5) Citigroup Global
Markets Inc., and (6) except in the case of a sale related to the exercise of
Call Warrants by the Depositor or any Affiliate thereof, Lehman Brothers Inc.
The Trustee shall not be responsible for the failure to obtain a bid so long
as it has made reasonable efforts to obtain bids. If a bid for the sale of the
Underlying Securities has been accepted by the Trustee but the sale has failed
to settle on the proposed settlement date, the Trustee shall request new bids
from such leading dealers. In the event of an Optional Exchange, the Trustee
shall only deliver the Underlying Securities to the purchaser of such
Underlying Securities or sell the Underlying Securities pursuant to this
Section 13, as the case may be, against payment in same day funds deposited
into the Certificate Account.

          Section 14.  Amendments. Notwithstanding anything in the Trust
Agreement to the contrary, in addition to the other restrictions on
modification and amendment contained therein, the Trustee shall not enter into
any amendment or modification of the Trust Agreement which would adversely
affect in any material respect the interests of the holders of any class of
Certificates without the consent of the holders of 100% of such class of
Certificates; provided, however, that no such amendment or modification will
be permitted which would cause the Trust to be taxed as an association or
publicly traded partnership taxable as a corporation for federal income tax
purposes. Unless otherwise agreed, the Trustee shall provide five Business
Days written notice to each Rating Agency before entering into any amendment
or modification of the Trust Agreement pursuant to this Section 14.

          Section 15.  Voting of Underlying Securities, Modification of
Indenture.

          (a)  The Trustee, as holder of the Underlying Securities, has the
right to vote and give consents and waivers in respect of the Underlying
Securities as permitted by the Depository and except as otherwise limited by
the Trust Agreement. In the event that the Trustee receives a request from the
Depository, the Underlying Securities Trustee or the Underlying Securities
Issuer for its consent to any amendment, modification or waiver of the
Underlying Securities, the Indenture or any other document thereunder or
relating thereto, or receives any other solicitation for any action with
respect to the Underlying Securities, the Trustee shall mail a notice of such
proposed amendment, modification, waiver or solicitation to each
Certificateholder of record as of such date. The Trustee shall request
instructions from the Certificateholders as to whether or not to consent to or
vote to accept such amendment, modification, waiver or solicitation. The
Trustee shall consent or vote, or refrain from consenting or voting, in the
same proportion as the Voting Rights of the Trust were actually voted or not
voted by the Certificateholders thereof as of a date determined by the Trustee
prior to the date on which such consent or vote is required; provided,
however, that, notwithstanding anything in the Trust Agreement to the
contrary, the Trustee shall at no time vote on or consent to any matter (i)
unless such vote or consent would not (based on an opinion of counsel) cause
the Trust to be taxed as an association or publicly traded partnership taxable
as a corporation under the Code, (ii) which would alter the timing or amount
of any payment on the Underlying Securities, including, without limitation,
any demand to accelerate the Underlying Securities, except in the event of a
default under the Underlying Securities or an event which with the passage of
time would become an event of default under the Underlying Securities and with
the unanimous consent of Certificateholders representing 100% of the aggregate
Voting Rights and 100% of the Warrant Holders, or (iii) which would result in
the exchange or substitution of any of the outstanding Underlying Securities
pursuant to

                                      25
<PAGE>

a plan for the refunding or refinancing of such Underlying Securities except
in the event of a default under the Indenture and only with the consent of
Certificateholders representing 100% of the aggregate Voting Rights and 100%
of the Warrant Holders. The Trustee shall have no liability for any failure to
act resulting from Certificateholders' late return of, or failure to return,
directions requested by the Trustee from the Certificateholders.

          (b)  In the event that an offer is made by the Underlying Securities
Issuer to issue new obligations in exchange and substitution for any of the
Underlying Securities, pursuant to a plan for the refunding or refinancing of
the outstanding Underlying Securities or any other offer is made for the
Underlying Securities, the Trustee shall notify the Class A-1
Certificateholders, Class A-2 Certificateholders and the Warrant Holders of
such offer promptly. Subject to the rights of the Warrant Holders to exercise
Call Warrants in connection with a tender offer for the Underlying Securities,
the Trustee must reject any such offer unless an Underlying Securities event
of default has occurred and the Trustee is directed by the affirmative vote of
Certificateholders representing 100% of the aggregate Voting Rights to accept
such offer and the Trustee has received the tax opinion described above. If
pursuant to the preceding sentence, the Trustee accepts any such offer the
Trustee shall promptly notify the Rating Agencies.

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

          Section 16.  Additional Depositor Representation. It is the express
intent of the parties hereto that the conveyance of the Underlying Securities
by the Depositor to the Trustee be, and be construed as, a sale of the
Underlying Securities by the Depositor and not a pledge of any Underlying
Securities by the Depositor to secure a debt or other obligation of the
Depositor. In the event that, notwithstanding the aforementioned intent of the
parties, any Underlying Securities are held to be property of the Depositor,
then, it is the express intent of the parties that such conveyance be deemed a
pledge of such Underlying Securities and all proceeds thereof by the Depositor
to the Trustee to secure a debt or other obligation of the Depositor, pursuant
to Section 10.07 of the Standard Terms. In connection with any such grant of a
security interest in the Underlying Securities and all proceeds thereof
(including any such grant in connection with any sale of additional Underlying
Securities pursuant to Section 3(d)), the Depositor hereby represents and
warrants to Trustee as follows:

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

         (ii)     The Underlying Securities have been credited to a
                  trust account (the "Securities Account") established in the
                  name of the Trustee in accordance with Section 2.01 of the
                  Standard Terms. U.S. Bank Trust National Association, as
                  securities

                                      26
<PAGE>

                  intermediary (the "Securities Intermediary") has
                  established the Securities Account and has agreed to treat
                  the Underlying Securities as "financial assets" within the
                  meaning of the UCC.

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

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

         (v)      The Depositor has taken all steps necessary to cause
                  the Securities Intermediary to identify on its records that
                  the Trustee is the Person owning the security entitlements
                  credited to the Securities Account.

         (vi)     Other than the security interest granted to the Trust
                  pursuant to this Agreement, the Depositor has not assigned,
                  pledged, sold, granted a security interest in or otherwise
                  conveyed any interest in the Underlying Securities (or, if
                  any such interest has been assigned, pledged or otherwise
                  encumbered, it has been released).  The Depositor has not
                  authorized the filing of and is not aware of any financing
                  statements against the Depositor that include a description
                  of the Underlying Securities other than any financing
                  statement relating to the security interest granted to the
                  Trust hereunder.  The Depositor is not aware of any judgment
                  or tax lien filings against the Depositor.

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

Trust, as defined below, the property of which consists principally of
$25,455,000 aggregate principal amount of 6.875% Notes due November 15, 2028,
issued by Sprint Capital Corporation (the "Underlying Securities Issuer") and
all payments received thereon (the "Trust Property"), deposited in trust by
Lehman ABS Corporation (the "Depositor").

         THIS CERTIFIES THAT CEDE & CO. is the registered owner of 1,000,000
Class A-1 Certificates issued by the Corporate Backed Trust Certificates,
Sprint Capital Note-Backed Series 2003-17 Trust (the "Trust"), having an
aggregate Certificate Principal Balance of $25,000,000, representing a
nonassessable, fully-paid, proportionate undivided beneficial ownership
interest in the Sprint Capital Note-Backed Series 2003-17 Trust, formed by the
Depositor.

         The Trust was created pursuant to a Standard Terms for Trust

         This Certificate is one of the duly authorized Certificates
designated as the "Corporate Backed Trust Certificates, Sprint Capital

                           (REVERSE OF CERTIFICATE)

The Certificates are limited in right of distribution to certain payments and
collections respecting the Underlying Securities, all as more specifically set
forth herein and in the Trust Agreement. The registered Holder hereof, by its
acceptance hereof, agrees that it will look solely to the Trust Property (to
the extent of its rights therein) for distributions hereunder.

The Trust Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor and the Trustee and the rights of the Certificateholders under the
Trust Agreement at any time by the Depositor and the Trustee with the consent
of the Holders of Class A-1 Certificates in the manner set forth in the Series
Supplement and the Standard Terms. Any such consent by the Holder of this
Certificate (or any predecessor Certificate) shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange hereof or in lieu
hereof whether or not a notation of such consent is made upon this
Certificate. The Trust Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of
the Certificates.

The Certificates are issuable in fully registered form only in denominations
of $25.

As provided in the Trust Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registerable in the Certificate

the offices or agencies of the Certificate Registrar maintained by the Trustee
in the Borough of Manhattan, the City of New York, duly endorsed by or
accompanied by an assignment in the form below and by such other documents as
required by the Trust Agreement, and thereupon one or more new Certificates of
the same class in authorized denominations evidencing the same principal
amount will be issued to the designated transferee or transferees. The initial
Certificate Registrar appointed under the Trust Agreement is U.S. Bank Trust
National Association.

No service charge will be made for any registration of transfer or exchange,
but the Trustee may require exchange of a sum sufficient to cover any tax or
other governmental charge that may be imposed in connection with any transfer
or exchange of Certificates.

The Depositor and the Trustee and any agent of the Depositor or the Trustee
may treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes, and neither the Depositor, the Trustee, nor any such
agent shall be affected by any notice to the contrary.

It is the intention of the parties to the Trust Agreement that the Trust
created thereunder shall constitute a fixed investment trust for federal
income tax purposes under Treasury Regulation Section 301.7701-4, and the
Certificateholder agrees to treat the Trust, any distributions therefrom and
its beneficial interest in the Certificates consistently with such
characterization.

The Trust and the obligations of the Depositor and the Trustee created by the
Trust Agreement with respect to the Certificates shall terminate upon the
earliest to occur of (i) the payment in full at maturity or sale by the Trust
after a payment default on or an acceleration or other early payment of the
Underlying Securities and the distribution in full of all amounts due to the
Class A-1 Certificateholders and Class A-2 Certificateholders; (ii) the
exercise of all outstanding Call

                           EXERCISE OF CALL WARRANTS

     Section 1.1 Manner of Exercise. (a) Call Warrants may be exercised by any
holder thereof (each, a "Warrant Holder") in whole or in part on any Call
Date. The following conditions shall apply to any exercise of Call Warrants:

               (i) A notice (each, a "Call Notice") specifying the number of
          Call Warrants being exercised and the Call Date shall be delivered
          to the Warrant Agent and the Trustee at least 5 Business Days before
          such Call Date.

                                     B-1

<PAGE>

               (ii) The Warrant Holder shall surrender the Call Warrants to
          the Warrant Agent at its office specified in Section 7.3 hereof no
          later than 10:00 a.m. (New York City time) on such Call Date.

               (iii) Except as otherwise provided herein in connection with a
          Call Notice relating to a tender offer for or redemption of
          Underlying Securities, the Warrant Holder shall have made payment to
          the Warrant Agent, by wire transfer or other immediately available
          funds acceptable to the Warrant Agent, in the amount of the Call
          Price, no later than 10:00 a.m. (New York City time) on the Call
          Date.

               (iv) The Warrant Holder may not exercise the Call Warrants at
          any time when such Warrant Holder is insolvent, and such Warrant
          Holder shall be required to certify that it is solvent at the time
          of exercise, by completing the form of subscription ("Form of
          Subscription") attached to the Call Warrants and delivering such
          completed Form of Subscription to the Trustee on or prior to the
          Call Date and by delivering to the Trustee a form reasonably
          satisfactory to the Trustee of the solvency certificate required
          pursuant to Section 7(d)(ii) of the Series Supplement.

               (v) The Warrant Holder shall have satisfied any other
          conditions to the exercise of Call Warrants set forth in Section
          7(d) of the Series Supplement.

          (b) Upon exercise of Call Warrants, any Warrant Holder other than
     the Depositor or any Affiliate of the Depositor shall be entitled to
     delivery by the Trustee of the Called Certificates. The "Called
     Certificates" shall be, in the case of the Class A-1 Certificates, Class
     A-1 Certificates having a Certificate Principal Balance equal to $25 per
     Call Warrant, and in the case of the Class A-2 Certificates, Class A-2
     Certificates having a Certificate Principal Balance equal to $250 per
     Call Warrant; provided, however, that Called Certificates that are Class
     A-2 Certificates must meet the minimum denomination requirements set
     forth in Section 3(a) of the Series Supplement. Unless otherwise
     specified therein, each Call Notice shall be deemed to be notice of an
     Optional Exchange pursuant to Section 7(b) of the Series Supplement (it
     being expressly understood that any Optional Exchange must comply with
     the provisions of Section 7(a) and 7(b) of the Series Supplement). Any
     Warrant Holder which is the Depositor or any Affiliate of the Depositor
     shall receive the proceeds of the sale of the Called Underlying
     Securities and shall not be entitled to receive the related Called
     Certificates or Called Underlying Securities. "Called Underlying
     Securities" are Underlying Securities which represent the same percentage
     of the Underlying Securities as the Called Certificates represent of the
     Class A-1 Certificates and the Class A-2 Certificates.

          (c) The Warrant Agent shall notify the Trustee immediately upon its
     receipt of a Call Notice and upon receipt of payment of the Call Price.
     The Warrant Agent shall transfer the amount of any paid Call Price to the
     Trustee in immediately available funds, for deposit in the Certificate
     Account and application pursuant to the Trust Agreement on the applicable
     Call Date (and, pending such transfer, shall hold such amount for the
     benefit of the Warrant Holder in a segregated trust account).

                                      B-2

<PAGE>

          (d) Delivery of a Call Notice does not give rise to an obligation on
     the part of the Warrant Holder to pay the Call Price. If, by 10:00 a.m.
     (New York City time) on the Call Date, the Warrant Holder has not paid
     the Call Price, except in connection with a Call Notice relating to a
     tender offer for or redemption of Underlying Securities, then the Call
     Notice shall automatically expire and none of the Warrant Holder, the
     Warrant Agent or the Trustee shall have any obligation with respect to
     the Call Notice. The expiration of a Call Notice shall in no way affect
     the Warrant Holder's right to deliver a Call Notice at a later date. The
     Call Price for a call in connection with a tender offer or redemption
     shall be deducted from the proceeds of a tender offer or a redemption by
     the Trust pursuant to Section 5(i)(iii) or Section 7(g)(iii), as
     applicable, of the Series Supplement.

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

          (a) if Call Warrants are being exercised by any Warrant Holder other
     than the Depositor or any Affiliate of the Depositor, to cause the Called
     Certificates to reflect the Warrant Holder's beneficial ownership of such
     Certificates and if such Call Notice is also deemed to be a notice of
     Optional Exchange (and the Warrant Holder otherwise complies with the
     provisions of Section 7(a) and Section 7(b) of the Series Supplement), to
     cause a distribution of Underlying Securities to the Warrant Holder in
     accordance with Section 7(a) of the Series Supplement, provided, however,
     that if such Call Notice and Optional Exchange is in connection with a
     tender offer or a redemption, the Warrant Agent shall instruct the
     Trustee to distribute to the exercising Warrant Holder the excess of the
     tender offer or redemption proceeds over the Call Price pursuant to
     Section 5(i)(iii) or Section 7(g)(iii), as applicable, of the Series
     Supplement, or

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

     If such exercise is in part only, the Warrant Agent shall (i) in the case
of a Global Call Warrant, cause the Registered Warrant Amount to be decreased
to reflect the outstanding Call Warrants of the Warrant Holder and (ii) in the
case of a Certificated Call Warrant, instruct the Trustee to authenticate new
Call Warrants of like tenor, representing the outstanding Call Warrants of the
Warrant Holder, and the Warrant Agent shall deliver such Call Warrants to the
Warrant Holder.

         In each case, the Trustee shall act in accordance with such
instructions.

     Section 1.3 Cancellation and Destruction of Call Warrants. All Call
Warrants surrendered to the Warrant Agent for the purpose of exercise (in
whole or in part) pursuant to Section 1.1 and actually exercised, or for the
purpose of transfer or exchange pursuant to Article IV, shall be cancelled by
the Warrant Agent, and no Call Warrant (other than that reflecting any

                                      B-3

<PAGE>

such transfer or exchange) shall be issued in lieu thereof. The Warrant Agent
shall destroy all cancelled Call Warrants.

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

     Section 1.5 Pro Rata Reduction of Call Warrants if Partial Redemption of
Underlying Securities. If Underlying Securities are redeemed in part by the
Underlying Securities Issuer and the Warrant Holders do not exercise their
Call Rights in connection with such partial redemption, the Warrant Amount or
Registered Warrant Amount, as the case may be, held by each Warrant Holder
shall be reduced proportionately so that the aggregate amount of Class A-1
Certificates callable by Call Warrants shall equal the amount of outstanding
Class A-1 Certificates after giving effect to such partial redemption and the
aggregate Certificate Principal Balance of Class A-2 Certificates callable by
Call Warrants shall equal the outstanding Certificate Principal Balance of
Class A-2 Certificates after giving effect to such partial redemption. The
Warrant Agent shall make such adjustments to its records as shall be necessary
to reflect such reductions and shall notify the Depository or each Warrant
Holder, as the case may be, of such adjustments.

                                  ARTICLE II

                               THE CALL WARRANTS

     Section 2.1 The Call Warrants.

          (a) The Call Warrants shall initially be issued as one or more
     Global Call Warrants in definitive, fully registered form without
     coupons, and DTC shall be the Depository. Upon issuance, the Global Call
     Warrants shall initially be deposited with the Trustee in its capacity as
     custodian on behalf of DTC. Such Global Call Warrants shall initially be
     registered in the name of Cede & Co. or another nominee designated by
     DTC. Global Call Warrants shall clear and settle in book-entry only form
     through the facilities of the Depository. Unless and until it is
     exchanged in whole or in part for Certificated Call Warrants, a Global
     Call Warrant may not be transferred except as a whole by the Depository
     for such Global Call Warrant to a nominee of such Depository, or by a
     nominee of such Depository to such Depository or another nominee of such
     Depository, or by such Depository or any such nominee to a successor of
     such Depository or a nominee of such successor. The Registered Warrant
     Amount of Call Warrants may from time to time be increased or decreased
     by adjustments made on the records of the Trustee, as custodian for DTC
     for such Global Call Warrant, as provided in this Section.

          (b) The Warrant Agent shall register the transfer or exchange of any
     Global Call Warrant without requiring any additional certification.

          (c) Interests of beneficial owners in a Global Call Warrant may be
     transferred in accordance with the rules and procedures of DTC and any
     other applicable

                                      B-4

<PAGE>

     Depositories. In connection with any exchange of beneficial ownership
     interests in a Global Call Warrant for Certificated Call Warrants
     pursuant to Section 2.3, the Warrant Agent shall reflect on its books and
     records the date of such exchange and a decrease in the Registered
     Warrant Amount of such Global Call Warrant in an amount equal to the
     Warrant Amount of the beneficial ownership interests in such Global Call
     Warrant being exchanged for Certificated Call Warrants.

     Section 2.2 Cancellation. All Call Warrants presented and surrendered for
payment, transfer or exchange shall be delivered to the Warrant Agent and
shall be promptly canceled by it. No Call Warrants shall be authenticated in
lieu of or in exchange for any Call Warrants canceled as provided in this
Section 2.2.

     Section 2.3 Certificated Call Warrants. Any Global Call Warrant
representing Call Warrants shall be exchangeable for Certificated Call
Warrants only if (i) the Depository advises the Depositor in writing that it
is no longer willing or able to properly discharge its responsibilities with
respect to the Call Warrants and the Depositor is unable to locate a qualified
successor within 60 calendar days or (ii) the Depositor, at its option,
advises the Trustee in writing that it elects to terminate the book-entry
system through the Depository. Any Global Call Warrant that is exchangeable
pursuant to the preceding sentence will be exchangeable for Certificated Call
Warrants of like tenor and Warrant Amount, as applicable, in any authorized
denomination or denominations and registered in the names of such Person or
Persons as the Depository shall direct. Upon such exchange, the Warrant Agent
shall execute and authenticate such Certificated Call Warrants and register
the same in the name of, and deliver the same to, such Person or Persons
consistent with the provisions hereof.

                                 ARTICLE III

                           RESTRICTIONS ON TRANSFER

     Section 3.1 Restrictive Legends. Except as otherwise permitted by this
Article III, each Call Warrant (including each Call Warrant issued upon the
transfer of any Call Warrant) shall be issued with a legend in substantially
the following form:

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

     THESE CALL WARRANTS ARE ONLY TRANSFERABLE IF TRANSFERRED WITH OTHER CALL
     WARRANTS WHICH, TOGETHER WITH THESE CALL WARRANTS, REPRESENT THE RIGHT TO
     CALL CLASS A-2 CERTIFICATES HAVING AN AGGREGATE PRINCIPAL BALANCE EQUAL
     TO, OR GREATER THAN, $100,000.

     EACH PURCHASER OF THIS CALL WARRANT IS HEREBY NOTIFIED THAT THE SELLER OF
     THIS CALL WARRANT MAY BE RELYING ON THE EXEMPTION

                                      B-5

<PAGE>

     FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE
     144A THEREUNDER."

     Section 3.2 Notice of Proposed Transfer. Prior to any transfer of any
Call Warrant or portion thereof, the Warrant Holder will give five (5)
Business Days (or such lesser period acceptable to the Warrant Agent) prior
written notice to the Warrant Agent of such Warrant Holder's intention to
effect such transfer.

                                  ARTICLE IV

               REGISTRATION AND TRANSFER OF CALL WARRANTS, ETC.

     Section 4.1 Warrant Register; Ownership of Call Warrants. The Warrant
Agent will keep a register in which the Warrant Agent will provide for the
registration of Call Warrants and the registration of transfers of Call
Warrants representing numbers of Call Warrants. Prior to due presentment of a
Call Warrant for registration of transfer, the Depositor, the Trustee, the
Warrant Agent and any agent of the Depositor, the Trustee or the Warrant Agent
may treat the Person in whose name any Call Warrant is registered as the owner
of such Call Warrant for any purposes whatsoever, and none of the Depositor,
the Trustee, the Warrant Agent or any agent of the Depositor, the Trustee or
the Warrant Agent shall be affected by notice to the contrary.

         None of the Depositor, the Trustee, the Warrant Agent or any agent of
the Depositor, the Trustee or the Warrant Agent shall have any responsibility
or liability for any aspect of the records relating to, or payments made on
account of, beneficial ownership interests of a Global Call Warrant or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.

         Notwithstanding the foregoing, with respect to any Global Call Warrant,
nothing herein shall prevent the Depositor, the Trustee, the Warrant Agent or
any agent of the Depositor, the Trustee or the Warrant Agent from giving
effect to any written certification, proxy or other authorization furnished by
any Depository, as a Warrant Holder, with respect to such Global Call Warrant
or impair, as between such Depository and owners of beneficial interests in
such Global Call Warrant, the operation of customary practices governing the
exercise of the rights of such Depository (or its nominee) as Warrant Holder
of such Global Call Warrant.

     Section 4.2 Transfer and Exchange of Call Warrants. (a) No Call Warrant
or any beneficial interest therein may be offered, resold, assigned or
otherwise transferred (including by pledge or hypothecation) unless such
offer, resale, assignment or transfer is to a qualified institutional buyer (a
"QIB"), as such term is defined in Rule 144A promulgated under the Securities
Act ("Rule 144A"), in accordance with Rule 144A, and in accordance with any
applicable securities laws of any state of the United States and other
jurisdictions. In addition, each Call Warrant relating to a Class A-2
Certificate may only be transferred with other Call Warrants relating to Class
A-2 Certificates, which together represent the right to call Class A-2
Certificates having an aggregate principal balance equal to, or greater than,
$100,000. Prior to any offer, resale, assignment or transfer of any
Certificated Call Warrant, the prospective transferee and the prospective
transferor shall be required to deliver to the Trustee an executed copy of an
Investment Letter with respect to the Certificated Call Warrants to be
transferred substantially in the form of Exhibit A hereto. Each prospective
transferee of any Certificated

                                      B-6

<PAGE>

Call Warrants shall acknowledge, represent and agree (and each prospective
transferee of any beneficial interest in a Global Call Warrant shall be deemed
to acknowledge, represent and agree) as follows:

     (1)  The transferee (x) is a QIB, (y) is aware that the sale to it is
          being made in reliance on Rule 144A and (z) is acquiring such Call
          Warrants for its own account or for the account of a QIB.

     (2)  The transferee understands that the Call Warrants are being offered
          in a transaction not involving any public offering in the United
          States within the meaning of the Securities Act, and that the Call
          Warrants have not been and will not be registered under the
          Securities Act.

     (3)  The transferee agrees that (A) if in the future it decides to offer,
          resell, pledge or otherwise transfer the Call Warrants prior to the
          Resale Restriction Termination Date, such Call Warrants shall only
          be offered, resold, assigned or otherwise transferred to a QIB, in
          accordance with Rule 144A, and in accordance with any applicable
          securities laws of any state of the United States and other
          jurisdictions and (B) the transferee will, and each subsequent
          holder is required to, notify any subsequent purchaser of such Call
          Warrants from it of the resale restrictions referred to in clause
          (A) above.

          (b) Upon surrender of any Call Warrant for registration of transfer
     or for exchange to the Warrant Agent, the Warrant Agent shall (subject to
     compliance with Article III) promptly execute and deliver, and cause the
     Trustee, on behalf of the Trust, to execute and deliver, in exchange
     therefor, a new Call Warrant of like tenor and evidencing a like number
     of Call Warrants, in the name of such Warrant Holder or as such Warrant
     Holder (upon payment by such Warrant Holder of any applicable transfer
     taxes or government charges) may direct; provided that as a condition
     precedent for transferring the Call Warrants, the prospective transferee
     shall deliver to the Trustee and the Depositor an executed copy of the
     Investment Letter (set forth as Exhibit A hereto) if the same is required
     pursuant to the provisions of clause (a) above.

     Section 4.3 Replacement of Call Warrants. Upon receipt of evidence
reasonably satisfactory to the Warrant Agent of the loss, theft, destruction
or mutilation of any Call Warrant and, in the case of any such loss, theft or
destruction of any Call Warrant, upon delivery of an indemnity bond in such
reasonable amount as the Warrant Agent may determine, or, in the case of any
such mutilation, upon the surrender of such Call Warrant for cancellation to
the Warrant Agent, the Warrant Agent shall execute and deliver, and cause the
Trustee, on behalf of the Trust, to execute and deliver, in lieu thereof, a
new Call Warrant of like tenor bearing a number not contemporaneously
outstanding.

     Section 4.4 Execution and Delivery of Call Warrants by Trustee. The
Trustee, on behalf of the Trust, hereby agrees (subject to compliance with
Article III) to execute and deliver such new Call Warrants issued in
accordance with Section 1.2 or this Article IV as the Warrant Agent shall
request in accordance herewith.

                                      B-7

     Section 4.5 Additional Call Warrants. The Trustee shall execute and
deliver, in a manner consistent with Article II hereof, additional Call
Warrants on behalf of the Trust with respect to any additional Certificates
issued by the Trust following the sale of additional Underlying Securities to
the Trust, in accordance with the provisions of Section 3(d) of the Series
Supplement.

                                 WARRANT AGENT

     Section 6.1 Limitation on Liability. The Warrant Agent shall be protected
and shall incur no liability for or in respect of any action taken, suffered
or omitted by it in connection with its administration of the Call Warrants in
reliance upon any instrument of assignment or transfer, power of attorney,
endorsement, affidavit, letter, notice, direction, consent, certificate,
statement or other paper or document in good faith believed by it to be
genuine and to be signed, executed and, where necessary, verified and
acknowledged, by the proper Person or Persons.

     Section 6.2 Duties of Warrant Agent. The Warrant Agent undertakes only
the specific duties and obligations imposed hereunder upon the following terms
and conditions, by all of which the Depositor, the Trust, the Trustee and each
Warrant Holder shall be bound:

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

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

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

          (d) The Warrant Agent shall not be liable for or by reason of any of
     the statements of fact or recitals contained herein or be required to
     verify the same, but all such statements and recitals are and shall be
     deemed to have been made by the Trust and the Depositor only.

          (e) The Warrant Agent shall not have any responsibility in respect
     of and makes no representation as to the validity of the Call Warrants or
     the execution and delivery thereof (except the due execution hereof by
     the Warrant Agent); nor shall it be responsible for any breach by the
     Trust of any covenant or condition contained in the Call Warrants; nor
     shall it by any act thereunder be deemed to make any representation or
     warranty as to the Certificates to be purchased thereunder.

          (f) The Warrant Agent is hereby authorized and directed to accept
     instructions with respect to the performance of its duties hereunder from
     the Chairman of the Board, the Chief Executive Officer, Chief Financial
     Officer, Chief Operating Officer, President, a Vice President, a Senior
     Vice President, a Managing Director, its Treasurer,

                                     B-10

     an Assistant Treasurer, its Secretary or an Assistant Secretary of the
     Depositor, and any Responsible Officer of the Trustee, and to apply to
     such officers for advice or instructions in connection with its duties,
     and it shall not be liable for any action taken or suffered to be taken
     by it in good faith in accordance with instructions of any such officer.

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

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

          (i) The Warrant Agent shall act solely as the agent of the Trust
     hereunder. The Warrant Agent shall not be liable except for the failure
     to perform such duties as are specifically set forth herein, and no
     implied covenants or obligations shall be read into the Call Warrants
     against the Warrant Agent, whose duties shall be determined solely by the
     express provisions thereof. The Warrant Agent shall not be deemed to be a
     fiduciary.

          (j) The Warrant Agent shall not be responsible for any failure on
     the part of the Trustee to comply with any of its covenants and
     obligations contained herein.

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

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

          (m) Upon request of a Warrant Holder, the Warrant Agent shall
     furnish to such Warrant Holder and/or a prospective purchaser designated
     by such Warrant Holder the information required to be delivered under
     Rule 144A(d)(4) under the Securities Act, to the extent that such
     information is in the possession of the Warrant Agent.

     Section 6.3 Change of Warrant Agent. The Warrant Agent may resign and be
discharged from its duties hereunder upon thirty (30) days notice in writing
mailed to the Depositor and the Trustee by registered or certified mail, and
to the Warrant Holders by first-class mail at the expense of the Depositor;
provided that no such resignation or discharge shall become effective until a
successor Warrant Agent shall have been appointed hereunder. The

                                     B-11

<PAGE>

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

     Section 6.4 Warrant Agent Transfer Fee. The Warrant Agent will assess a
fee of $50.00 upon the issue of any new Call Warrant, such fee to be assessed
upon the new Warrant Holder.

                                 ARTICLE VII

                                 MISCELLANEOUS

     Section 7.1 Remedies. The remedies at law of the Warrant Holder in the
event of any default or threatened default by the Warrant Agent in the
performance of or compliance with any of the terms of the Call Warrants are
not and will not be adequate and, to the full extent permitted by law, such
terms may be specifically enforced by a decree for the specific performance of
any agreement contained herein or by an injunction against a violation of any
of the terms thereof or otherwise.

     Section 7.2 Limitation on Liabilities of Warrant Holder. Nothing
contained in this Warrant Agent Agreement shall be construed as imposing any
obligation on the Warrant Holder to purchase any of the Certificates except in
accordance with the terms thereof.

     Section 7.3 Notices. All notices and other communications under this
Warrant Agent Agreement shall be in writing and shall be delivered, or mailed
by registered or certified mail, return receipt requested, by a nationally
recognized overnight courier, postage prepaid, addressed (a) if to any Warrant
Holder, at the registered address of such Warrant Holder as set forth in the
register kept by the Warrant Agent or (b) if to the Warrant Agent, to 100 Wall
Street, Suite 1600, New York, New York 10005, Attention: Corporate Trust or to
such other address notice of which the Warrant Agent shall have given to the
Warrant Holder and the Trustee or (c) if to the Trust or the Trustee, to the
Corporate Trust Office (as set forth in the Trust Agreement); provided that
the exercise of any Call Warrants shall be effective in the manner provided in
Article I. The Warrant Agent shall forward to the Warrant Holder any notices
received by it

                                     B-12

hereunder or pursuant to the Trust Agreement or this Agreement by facsimile
within one Business Day of receipt thereof.

     Section 7.4 Amendment. (a) This Warrant Agent Agreement may be amended
from time to time by the Depositor, the Trustee and the Warrant Agent without
the consent of any Warrant Holder, upon receipt of an opinion of counsel
satisfactory to the Warrant Agent that the provisions hereof have been
satisfied and that such amendment would not cause the Trust to be taxed as an
association or publicly traded partnership taxable as a Corporation under the
Code, for any of the following purposes: (i) to cure any ambiguity or to
correct or supplement any provision herein which may be defective or
inconsistent with any other provision herein or to provide for any other terms
or modify any other provisions with respect to matters or questions arising
under the Call Warrant which shall not adversely affect in any material
respect the interests of the Warrant Holder or any holder of a Certificate;
provided, however, that no amendment altering the timing or amount of any
payment of the Call Price shall be effected without the consent of each
Warrant Holder; or (ii) to evidence and provide for the acceptance of
appointment hereunder of a Warrant Agent other than U.S. Bank Trust National
Association.

          (b) Without limiting the generality of the foregoing, the Call
     Warrants may also be modified or amended from time to time by the
     Depositor, the Trustee and the Warrant Agent with the consent of Warrant
     Holders of 66-2/3% of each of the Call Warrants related to the Class A-1
     Certificates and the Call Warrants related to the Class A-2 Certificates,
     upon receipt of an opinion of counsel satisfactory to the Warrant Agent
     that the provisions hereof (including, without limitation, the following
     proviso) have been satisfied, for the purpose of adding any provisions to
     or changing in any manner or eliminating any of the provisions of the
     Call Warrants or of modifying in any manner the rights of the Warrant
     Holders; provided, however, that no such amendment shall (i)
     adversely affect in any material respect the interests of holders of
     Certificates without the consent of the holders of Certificates
     evidencing not less than the Required Percentage--Amendment of the
     aggregate Voting Rights of such affected Certificates (as such terms are
     defined in the Trust Agreement) and without written confirmation from the
     Rating Agencies that such amendment will not result in a downgrading or
     withdrawal of its rating of the Certificates; (ii) alter the terms on
     which Call Warrants are exercisable or the amounts payable upon exercise
     of a Warrant without the consent of the holders of Certificates
     evidencing not less than 100% of the aggregate Voting Rights of such
     affected Certificates and 100% of the affected Warrant Holders or (iii)
     reduce the percentage of aggregate Voting Rights required by (i) or (ii)
     without the consent of the holders of all such affected Certificates.
     Notwithstanding any other provision of this Warrant Agent Agreement, this
     Section 7.4(b) shall not be amended without the consent of 100% of the
     affected Warrant Holders.

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

                                     B-13
<PAGE>

     the authorization of the execution thereof shall be subject to such
     reasonable regulations as the Warrant Agent may prescribe.

     Section 7.5 Expiration. The right to exercise the Call Warrants shall
expire on the earliest to occur of (a) the cancellation thereof, (b) the
termination of the Trust Agreement, or (c) the liquidation, disposition, or
maturity of all of the Underlying Securities.

     Section 7.6 Descriptive Headings. The headings in this Warrant Agent
Agreement are for purposes of reference only and shall not limit or otherwise
affect the meaning hereof.

     Section 7.7 GOVERNING LAW. THIS AGREEMENT SHALL BE CONSTRUED AND ENFORCED
IN ACCORDANCE WITH, AND THE RIGHTS OF THE PARTIES SHALL BE GOVERNED BY, THE
LAW OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF
LAWS.

     Section 7.8 Judicial Proceedings; Waiver of Jury. Any judicial proceeding
brought against the Trust, the Trustee or the Warrant Agent with respect to
this Warrant Agent Agreement may be brought in any court of competent
jurisdiction in the County of New York, State of New York or of the United
States of America for the Southern District of New York and, by execution and
delivery of the Call Warrants, the Trustee on behalf of the Trust and the
Warrant Agent (a) accept, generally and unconditionally, the nonexclusive
jurisdiction of such courts and any related appellate court, and irrevocably
agree that the Trust, the Trustee and the Warrant Agent shall be bound by any
judgment rendered thereby in connection with this Warrant Agent Agreement or
the Call Warrants, subject to any rights of appeal, and (b) irrevocably waive
any objection that the Trust, the Trustee or the Warrant Agent may now or
hereafter have as to the venue of any such suit, action or proceeding brought
in such a court or that such court is an inconvenient forum.

     Section 7.9 Nonpetition Covenant; No Recourse. Each of (i) the Warrant
Holder by its acceptance thereof, and (ii) the Warrant Agent agrees, that it
shall not (and, in the case of the Warrant Holder, that it shall not direct
the Warrant Agent to), until the date which is one year and one day after the
payment in full of the Certificates and all other securities issued by the
Trust, the Depositor or entities formed, established or settled by the
Depositor, acquiesce, petition or otherwise invoke or cause the Trust, the
Depositor, or any such other entity to invoke the process of the United States
of America, any State or other political subdivision thereof or any entity
exercising executive, legislative, judicial, regulatory or administrative
functions of or pertaining to government for the purpose of commencing or
sustaining a case by or against the Trust, the Depositor or any such other
entity under a federal or state bankruptcy, insolvency or similar law or
appointing a receiver, liquidator, assignee, trustee, custodian, sequestrator
or other similar official of the Trust, the Depositor or any such other entity
or all or any part of the property or assets of Trust, the Depositor or any
such other entity or ordering the winding up or liquidation of the affairs of
the Trust, the Depositor or any such other entity.

         Re:      Corporate Backed Trust Certificates, Sprint Capital
                  Note-Backed Series 2003-17
                  ---------------------------------------------------

Ladies and Gentlemen:

          In connection with its proposed purchase of Call Warrants (the "Call
Warrants") which represent the right to call $______________ aggregate of
Corporate Backed Trust Certificates, Sprint Capital Note-Backed Series 2003-17
Class A-1 Certificates and $_______________ aggregate Certificate Principal
Balance of Corporate Backed Trust Certificates, Sprint Capital Note-Backed
Series 2003-17 Class A-2 Certificates, the undersigned purchaser (the
"Purchaser") confirms that:

     1. The Purchaser understands that substantial risks are involved in an
investment in the Call Warrants. The Purchaser represents that in making its
investment decision to acquire the Call Warrants, the Purchaser has not relied
on representations, warranties, opinions, projections, financial or other
information or analysis, if any, supplied to it by any person, including you,
Lehman ABS Corporation, as depositor (the "Depositor"), or U.S. Bank Trust
National Association, as trustee (the "Trustee"), or any of your or their
affiliates, except as expressly contained in written information, if any. The
Purchaser has such knowledge and experience in financial and business matters
as to be capable of evaluating the merits and risks of an investment in the
Call Warrants, and the Purchaser is able to bear the substantial economic
risks of such an investment. The Purchaser has relied upon its own tax, legal
and financial advisors in connection with its decision to purchase the Call
Warrants.

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

                                     A-1
<PAGE>

     3. The Purchaser understands that the Call Warrants have not been and
will not be registered under the 1933 Act or under the securities or blue sky
laws of any state, and that (i) if it decides to resell, pledge or otherwise
transfer any Security, such resale, pledge or other transfer must comply with
the provisions of the Warrant Agent Agreement relating to the Call Warrants
(including, without limitation, the provisions of Section 4.2 thereof) and
(ii) it will, and each subsequent holder will be required to, notify any
purchaser of any Security from it of the resale restrictions referred to in
clause (i) above.

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

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

          THESE CALL WARRANTS ARE ONLY TRANSFERABLE IF TRANSFERRED
          WITH OTHER CALL WARRANTS WHICH, TOGETHER WITH THESE CALL
          WARRANTS, REPRESENT THE RIGHT TO CALL CLASS A-2
          CERTIFICATES HAVING AN AGGREGATE PRINCIPAL BALANCE EQUAL
          TO, OR GREATER THAN, $100,000.

          EACH PURCHASER OF THIS CALL WARRANT IS HEREBY NOTIFIED
          THAT THE SELLER OF THIS CALL WARRANT MAY BE RELYING ON THE
          EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE
          SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER."

     5. The Purchaser understands that no subsequent transfer of the Call
Warrants is permitted unless (A) such transfer is of a Call Warrant with the
applicable minimum denomination and aggregate principal balance transfer
requirement and (B) the Purchaser causes the proposed transferee to provide to
the Depositor and the Trustee such documentation as may be required pursuant
to Section 4.2 of the Warrant Agent Agreement, including, if required, a
letter substantially in the form hereof, or such other written statement as
the Depositor shall reasonably prescribe.

     6. The Purchaser is a person or entity (a "Person") who is either

          A. (1) a citizen or resident of the United States, (2) a
     corporation, partnership or other entity organized in or under the laws
     of the United States or any political subdivision thereof, or (3) an
     estate the income of which is includible in gross income for

                                     A-2
<PAGE>

     federal income tax purposes regardless of source, or (4) a trust if a
     court within the United States is able to exercise primary supervision of
     the administration of the trust and one or more United States persons
     have the authority to control all substantial decisions of the trust, or

          B. a Person not described in (A), whose ownership of such Call
     Warrant is effectively connected with such Person's conduct of a trade or
     business within the United States within the meaning of the Internal
     Revenue Code of 1986, as amended (the "Code"), and its ownership of any
     interest in such Call Warrant will not result in any withholding
     obligation with respect to any payments with respect to the Call Warrants
     by any Person (other than withholding, if any, under Section 1446 of the
     Code), or

          C. a Person not described in (A) or (B) above, who is not a Person:
     (1) that owns, directly or indirectly, 10% or more of the total combined
     voting power of all classes of stock in the Underlying Securities Issuer
     (as defined in the Prospectus Supplement) entitled to vote, (2) that is a
     controlled foreign corporation related to the Underlying Securities
     Issuer within the meaning of Section 864(d)(4) of the Code, or (3) that
     is a bank extending credit pursuant to a loan agreement entered into in
     the ordinary course of its trade or business.

     7. The Purchaser agrees that (I) if it is a Person described in clause
(A) above, it will furnish to the Depositor and the Trustee a properly
executed IRS Form W-9, and (II) if it is a Person described in clause (B)
above, it will furnish to the Depositor and the Trustee a properly executed
IRS Form W-8ECI, and (III) if it is a Person described in clause (C) above, it
will furnish to the Depositor and the Trustee a properly executed IRS Form
W-8BEN (or, if the Purchaser is treated as a partnership for federal income
tax purposes, a properly executed IRS Form W-8IMY with appropriate
certification for all partners or members attached). The Purchaser also agrees
that it will provide a new IRS form upon the expiration or obsolescence of any
previously delivered form, and that it will provide such other certifications,
representations or Opinions of Counsel as may be requested by the Depositor
and the Trustee.

     8. The Purchaser agrees that if at some time in the future it wishes to
transfer or exchange any of the Call Warrants, it will not transfer or
exchange any of the Call Warrants unless such transfer or exchange is in
accordance with the terms of the Warrant Agent Agreement, Series Supplement
and other documents applicable to the Call Warrant. The Purchaser understands
that any purported transfer of the Call Warrants (or any interest therein) in
contravention of any of the restrictions and conditions in the agreements, as
applicable, shall be void, and the purported transferee in such transfer shall
not be recognized by any Person as a holder of such Call Warrants, for any
purpose.

Ladies and Gentlemen:

                  In connection with our proposed purchase of $______________
aggregate principal amount of Class A-2 Certificates (the "Class A-2
Certificates") representing an interest in the Corporate Backed Trust
Certificates, Sprint Capital Note-Backed Series 2003-17 Trust (the "Trust"),
the undersigned, by executing this letter (the "Purchaser") confirms that:

     1.   The Purchaser understands that substantial risks are involved in an
          investment in the Class A-2 Certificates. The Purchaser represents
          that, in making its investment decision to acquire the Class A-2
          Certificates, the Purchaser has not relied on representations,
          warranties, opinions, projections, financial or other information or
          analysis, if any, supplied to it by any person or entity, including
          the Initial Purchaser, the Depositor or the Trustee or any of their
          affiliates, except as expressly contained in written information, if
          any. The Purchaser is purchasing the Class A-2 Certificates for
          investment purposes and not with a view to, or for, the offer or
          sale in connection with a public distribution or in any other manner
          that would violate the Securities Act or the securities or blue sky
          laws of any state of the United States. The Purchaser has such
          knowledge and experience in financial and business matters as to be
          capable of evaluating the merits and risks of purchasing any of the
          Class A-2 Certificates. The Purchaser is aware that it may be
          required to bear the substantial economic risk of an investment in
          the Class A-2 Certificates for an indefinite period of time and such
          Purchaser is able to bear such risk for an indefinite period. The
          Purchaser has relied upon its own tax, legal and financial advisors
          in connection with its decision to purchase the Class A-2
          Certificates.

                                     C-1

     2.   The Purchaser is not an "affiliate" (as defined in Rule 144 under
          the Securities Act) of the Depositor and is either:

          (i) (A) a "Qualified Institutional Buyer" (a "QIB"), within the
          meaning of Rule 144A under the Securities Act of 1933, as amended
          (the "Securities Act" and "Rule 144A") and has delivered to you the
          certification contained herein as to the fact that it is a QIB and
          (B) acquiring the Class A-2 Certificates for its own account, for the
          account of an Accredited Investor (as defined in Rule 501(a) under
          the Securities Act), or for the account of a QIB as to each of which
          the Purchaser exercises sole investment discretion. The Purchaser is
          aware that the Class A-2 Certificates are being sold to it in
          reliance on the exemption from the provisions of Section 5 of the
          Securities Act provided by Rule 144A; or

          (ii) an Accredited Investor and, if the Class A-2 Certificates are to
          be purchased for one or more accounts ("investor accounts") for which
          it is acting as fiduciary or agent, each such investor account is an
          Accredited Investor on a like basis or a QIB; in the normal course of
          its business, such Purchaser invests in or purchases securities
          similar to the Class A-2 Certificates.

     3.   The Purchaser acknowledges that neither the Depositor nor the
          Initial Purchaser, or any person representing the Depositor or the
          Initial Purchaser, has made any representation to such purchaser
          with respect to the Trust, the Underlying Securities or the offering
          or sale of any Class A-2 Certificates.

     4.   The Purchaser understands that the Class A-2 Certificates are being
          offered in a transaction not involving any public offering in the
          United States within the meaning of the Securities Act, that the
          Class A-2 Certificates have not been and will not be registered
          under the Securities Act or under the securities or blue sky laws of
          any state, and that (i) if in the future it decides to offer,
          resell, pledge or otherwise transfer the Class A-2 Certificates,
          such Class A-2 Certificates shall only be offered, resold, assigned
          or otherwise transferred (A) to the Trust, (B) pursuant to an
          effective registration statement under the Securities Act, (C) to a
          QIB, in accordance with Rule 144A or (D) to any person or entity
          (including an Accredited Investor within the meaning of Rule 501(a)
          under the Securities Act) pursuant to another available exemption
          from registration provided under the Securities Act, and, in each of
          cases (A) through (D), in accordance with any applicable securities
          laws of any state of the United States and other jurisdictions and
          (ii) the purchaser will, and each subsequent holder is required to,
          notify any subsequent purchaser of such Class A-2 Certificates from
          it of the resale restrictions referred to in clause (i) above. Upon
          the transfer of Class A-2 Certificates held in the form of global
          certificates to an Accredited Investor, the transferor's interest in
          such global certificates shall be exchanged for a Class A-2
          Certificate in definitive form. Thereafter, upon transfer of a
          definitive Class A-2 Certificate to a QIB, such Class A-2
          Certificate may be exchanged for a beneficial interest in a global
          certificate.

     5.   The Purchaser understands that each Class A-2 Certificate will,
          unless otherwise agreed to by the Depositor and the Trustee, bear a
          legend substantially to the following effect:

                                     C-2
<PAGE>

                  "THIS CLASS A-2 CERTIFICATE (OR ITS PREDECESSOR) HAS NOT
                  BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
                  AMENDED, AND MAY NOT BE TRANSFERRED, SOLD OR OTHERWISE
                  DISPOSED OF EXCEPT WHILE A REGISTRATION UNDER SUCH ACT IS IN
                  EFFECT OR PURSUANT TO AN EXEMPTION THEREFROM UNDER SUCH ACT.
                  THE CLASS A-2 CERTIFICATE REPRESENTED HEREBY MAY BE
                  TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF THE SERIES
                  SUPPLEMENT.

                  EACH PURCHASER OF THIS CLASS A-2 CERTIFICATE IS HEREBY
                  NOTIFIED THAT THE SELLER OF THIS CLASS A-2 CERTIFICATE MAY
                  BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5
                  OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER."

     6.   The Purchaser understands that no subsequent transfer of the Class
          A-2 Certificates is permitted unless (A) such transfer is of a Class
          A-2 Certificate with a denomination of at least $100,000 and (B) it
          causes its proposed transferee to provide to the Trustee and the
          Initial Purchaser a letter substantially in the form of Exhibit C to
          the Series Supplement and otherwise satisfactory to the Trustee and
          Initial Purchaser, as applicable, or such other written statement as
          the Depositor shall prescribe.

     7.   The Purchaser agrees that if at some time in the future it wishes to
          transfer or exchange any of the Class A-2 Certificates, it will not
          transfer or exchange any of the Class A-2 Certificates unless such
          transfer or exchange is in accordance with Section 5.04 of the Trust
          Agreement. The Purchaser understands that any purported transfer of
          the Class A-2 Certificates (or any interest therein) in
          contravention of any of the restrictions and conditions in the Trust
          Agreement, as applicable, shall be void, and the purported
          transferee in such transfer shall not be recognized by the Trust or
          any other Person as a Certificateholder, as the case may be, for any
          purpose.

     8.   The purchaser (i) acknowledges that the Depositor, the Initial
          Purchaser, the Trustee and others will rely upon the truth and
          accuracy of the foregoing acknowledgments, representations and
          agreements and agrees that the Depositor, the Initial Purchaser and
          the Trustee are irrevocably authorized to produce this letter or a
          copy hereof to any interested party in any administrative or legal
          proceeding or official inquiry with respect to the matters covered
          hereby, and (ii) agrees that, if any of the acknowledgments,
          representations, warranties and agreements made or deemed to have
          been made by such purchaser's purchase of the Class A-2 Certificates
          are no longer accurate, such purchaser shall promptly notify the
          Depositor and the Initial Purchaser. If the purchaser is acquiring
          any Class A-2 Certificates as a fiduciary or agent for one or more
          investor accounts, it represents that it has sole investment
          discretion with respect to each such account and it has full power
          to make the foregoing acknowledgments, representations

                                     C-3

          and agreements on behalf of each such account and that each such
          investor account is eligible to purchase the Class A-2 Certificates.

                  You and the Trustee are entitled to rely upon this letter
and are irrevocably authorized to produce this letter or a copy hereof to any
interested party in any administrative or legal proceeding or official inquiry
with respect to the matters covered hereby.

                                               Very truly yours,

	Re:	 	
Swap Transaction (Our Ref. No. 300323 / 353660)

Dear Sir/Madam:

     The purpose of this letter agreement is to set forth the terms and
conditions of the Swap Transaction entered into between the BANK OF MONTREAL
(“BMO”) and HUB International Limited (“Counterparty”) on the Trade Date
specified below (the “Swap Transaction”). This letter agreement will
constitute a “Confirmation” as referred to in the Agreement specified below.

     The definitions and provisions contained in the 2000 ISDA Definitions, as
published by the International Swaps and Derivatives Association, Inc., are
incorporated into this Confirmation. In the event of any inconsistency between
those definitions and provisions and this Confirmation, this Confirmation will
govern.

     This Confirmation evidences a complete binding agreement between BMO and
the Counterparty. This Confirmation constitutes a Confirmation subject to the
terms of a master agreement (the “Agreement”). The Agreement shall be in the
form of the 1992 Master Agreement (Multicurrency-Cross Border) published by the
International Swaps and Derivatives Association, Inc. (the “ISDA” Form) with
such modifications as BMO and the Counterparty shall in good faith agree.
Until BMO and the Counterparty execute and deliver the Agreement, (i) BMO and
the Counterparty shall be deemed to have entered into an agreement in the form
of the ISDA Form (without a Schedule), governed by the laws of the State of New
York and (ii) this Confirmation, together with all other documents (each an
“Other Confirmation”) confirming Specified Transactions (as defined in the ISDA
Form) (this Swap Transaction together with such Specified Transactions,
collectively, “Transactions”) heretofore, now or hereafter entered into between
BMO and the Counterparty (except any Other Confirmation that expressly provides
to the contrary), shall supplement, form a part of, and be subject to, an
agreement in the form of such ISDA Form as if BMO and the Counterparty had
executed an agreement in such form on the Trade Date of the first such
Transaction between BMO and the Counterparty. Upon such execution and delivery
of the Agreement, the terms thereof shall supercede such ISDA Form as
applicable to this Swap Transaction and the other Transactions, and this
Confirmation and the Other Confirmations shall supplement, form a part of, and
be subject to, the Agreement.

Transaction on the 4th Anniversary of the Effective Date (the “Optional
Termination Date”), by providing at least 5 days prior notice to the other

were an Early Termination Date designated as a result of the occurrence
of an Event of Default with respect to the Terminating Party and the
parties had specified Market Quotation and the Second Method for that
purpose.

	 	 	Promptly following a resolution pursuant to this paragraph, the Market Value
will be paid by the relevant party on the second Business Day following the
