subject to the terms and conditions hereof.

        NOW, THEREFORE, in consideration of the
premises and of the mutual covenants contained herein, and other good and
valuable consideration the receipt and adequacy of which are hereby
acknowledged, the parties hereto hereby agree as follows:

        1.

the meanings ascribed to such terms in the Credit Agreement.

 

       
2.

(b) the occurrence of an Additional Default (as defined below) under the Loan

                        (b)       Nothing herein shall limit or restrict in
any way the rights and remedies of Agent or any Lender with respect to any
Unmatured Event of Default or Event of Default other than the Events of Default

breach by the Borrower of any covenant contained in Section 4 of this
Agreement) (collectively, the "Additional Defaults" and,
individually, each an "Additional Default").

                        (c)       Notwithstanding the agreement under this

hereby shall be known as the "Corporate Backed Trust Certificates, BellSouth
Telecommunications Debenture-Backed Series 2003-14 Trust." The Certificates
evidencing certain undivided ownership interests therein shall be known as
"Corporate Backed Trust Certificates, BellSouth Telecommunications
Debenture-Backed Series 2003-14." The Certificates shall consist of the Class
A-1 Certificates and the Class A-2 Certificates (together, the
"Certificates"). The Trust is also issuing call warrants with respect to the
Certificates ("Call Warrants").

      (a) The Class A-1 Certificates shall be held through the Depository in
book-entry form and shall be substantially in the form attached hereto as
Exhibit A-1. The Class A-2 Certificates shall initially be held through the
Depository in book-entry form and, as set forth in Section 3(e) below, shall
be held subsequent to the Closing Date in physical form or through the
Depository in book-entry form and shall be substantially in the form attached
hereto as Exhibit A-2. The Class A-1 Certificates shall be issued in
denominations of $25. The Class A-2 Certificates shall be issued in minimum
denominations of $125 and in integral multiples of $1 in excess thereof;
provided, however, that (i) each Class A-2 Certificate may only be transferred
with other Class A-2 Certificates which together have an aggregate principal
balance equal to, or greater than, $100,000 and (ii) on any Call Date on which
a Warrant Holder shall concurrently exchange Called Certificates for a
distribution of Underlying Securities in accordance with the provisions of
Section 7 hereof, Called Certificates may be issued in other denominations.
Except as provided in the Standard Terms and in paragraph (d) in this Section,
the Trust shall not issue additional Certificates or additional Call Warrants
or incur any indebtedness.

      (b) The Class A-1 Certificates shall consist initially of 1,031,510
Certificates having an initial aggregate certificate principal balance (the

Principal Balance of $1,212,250.

      (c) The holders of the Class A-1 Certificates will be entitled to
receive on each Distribution Date the interest, if any, received on the
Underlying Securities, to the extent necessary to pay interest at a rate of
6.125% per annum on the outstanding Certificate Principal Balance of the Class
A-1 Certificates. The holders of the Class A-2 Certificates will not be
entitled to receive interest. On the Distribution Date occurring in November
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

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

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) unless such Class
A-2 Certificate shall be transferred with other Class A-2 Certificates which
together have an aggregate Certificate Principal Balance equal to, or greater
than, $100,000. In addition, no Class A-2 Certificate may be offered, resold,
assigned or otherwise transferred (including by pledge or hypothecation) at

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

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

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
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

            QIB.

            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,

            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

            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

            ACCORDANCE WITH THE TERMS OF THE SERIES SUPPLEMENT.

            THIS CLASS A-2 CERTIFICATE IS ONLY TRANSFERABLE IF
            TRANSFERRED WITH OTHER CLASS A-2 CERTIFICATES WHICH,
            TOGETHER WITH THIS CERTIFICATE, HAVE AN AGGREGATE
            PRINCIPAL BALANCE EQUAL TO, OR GREATER THAN, $100,000.

            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."

      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 6.125% 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:

                                      11
<PAGE>

                  (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.

            (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 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.

                                      12
<PAGE>

      (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 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.

                                      13

      (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: 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. 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

                                      14
<PAGE>

      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 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

                                      15
<PAGE>

      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 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 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.

                                      17
<PAGE>

            (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 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) An opinion of counsel to the Warrant Holder shall have been
      delivered to the Rating Agencies, in form satisfactory to the Rating
      Agencies, indicating that payment of the Call Price shall not be
      recoverable as a preferential transfer or fraudulent conveyance under
      the United States Bankruptcy Code. Such opinion may contain customary
      assumptions and qualifications.

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

            (iii) 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.

                                      18
<PAGE>

            (iv) 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.

            (v) 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 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.

            (vi) 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.

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

      (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

                                      19
<PAGE>

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 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

                                      20
<PAGE>

such notice if in good faith it determines that the withholding of such notice
is in the interest of the Certificateholders.

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

      (j) In the event that the Internal Revenue Service challenges the
characterization of the Trust as a grantor trust, the Trustee shall then file

pursuant to Section 761 of the Code to exclude the Trust from the

                                      21
<PAGE>

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

      (o) The Trust will not merge or consolidate with any other entity

      (r) The provisions of Section 2.01(d)(iii) of the Standard Terms shall
not apply to the BellSouth Telecommunications Debenture-Backed Series 2003-14
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

                                      23
<PAGE>

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
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

                                      24
<PAGE>

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 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

                                      25
<PAGE>

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 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

                                      26
<PAGE>

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 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 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

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

Register without the presentation or surrender of this Certificate or the
making of any notation hereon, except that with respect to Certificates
registered on the Record Date in the name of the nominee of the Clearing
Agency (initially, such nominee shall be Cede & Co.), payments will be made by
wire transfer in immediately available funds to the account designated by such
nominee. Except as otherwise provided in the Trust Agreement and
notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the Corporate
Trust Office or such other location as may be specified in such notice.

            Reference is hereby made to the further provisions of this
Certificate set forth on the reverse hereof, which further provisions shall
for all purposes have the same effect as if set forth at this place.

            Unless the certificate of authentication hereon has been executed
by or on behalf of the Trustee, by manual signature, this Certificate shall
not entitle the Holder hereof to any benefit under the Trust Agreement or be
valid for any purpose.

            THIS CERTIFICATE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF
THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS,

                   TRUSTEE'S CERTIFICATE OF AUTHENTICATION

            This is one of the Corporate Backed Trust Certificates, BellSouth

Agreement referred to herein.

                           (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-2 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 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 $125 and in integral multiples of $1 in excess thereof;
provided, however, that each Class A-2 Certificate may only be transferred
with other Class A-2 Certificates which together have an aggregate principal
balance equal to, or greater than, $100,000.

            As provided in the Trust Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is
registerable in the Certificate Register upon surrender of this Certificate
for registration of transfer at 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 Warrants by the
Warrant Holders; (iii) the Final Scheduled 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.

            An employee benefit plan subject to the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), a plan described in Section
4975(e) of the Code, an entity whose underlying assets include plan assets by
reason of any such plan's investment in the entity, including an individual
retirement account or Keogh plan (any such, a "Plan") may purchase and hold
Certificates if the Plan can represent and warrant that its purchase and
holding of the Certificates would not be prohibited under ERISA or the Code.

                        FORM OF WARRANT AGENT AGREEMENT

                      CORPORATE BACKED TRUST CERTIFICATES

      BELLSOUTH TELECOMMUNICATIONS DEBENTURE-BACKED SERIES 2003-14 TRUST

            WARRANT AGENT AGREEMENT, dated as of August 12, 2003 (the "Warrant
Agent Agreement"), by and between LEHMAN ABS CORPORATION, as Depositor (the
"Depositor"), U.S. BANK TRUST NATIONAL ASSOCIATION, as Trustee (the "Trustee")
and U.S. BANK TRUST NATIONAL ASSOCIATION, as Warrant Agent (the "Warrant
Agent").

                                W I T N E S S E T H:

            WHEREAS, the Depositor created Corporate Backed Trust
Certificates, BellSouth Telecommunications Debenture-Backed Series 2003-14
Trust (the "Trust"), a trust created under the laws of the State of New York
pursuant to a Standard Terms for Trust Agreements, dated as of January 16,
2001 (the "Agreement"), between Lehman ABS Corporation (the "Depositor") and
U.S. Bank Trust National Association, a national banking association, not in
its individual capacity but solely as Trustee (the "Trustee"), as supplemented
by the Series Supplement 2003-14, dated as of August 12, 2003 (the "Series
Supplement" and, together with the Agreement, the "Trust Agreement"), between
the Depositor and the Trustee; and

            WHEREAS, in connection with the creation of the Trust and the
deposit therein of the Underlying Securities, it is desired to provide for the
issuance of trust certificates (the "Certificates") evidencing undivided
interests in the Trust and call warrants with respect to the Certificates
("Call Warrants").

            NOW, THEREFORE, in consideration of the foregoing premises and the
mutual covenants expressed herein, it is hereby agreed by and between the
Depositor, the Warrant Agent and the Trustee that except as otherwise
specified herein or as the context may otherwise require, capitalized terms
used herein but not defined herein shall have the respective meanings set
forth below in the Series Supplement, and as follows:

                                  ARTICLE I

                           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:

                                     B-1
<PAGE>

                  (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.

                  (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 $125 per
      Call Warrant. 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

                                     B-2
<PAGE>

      the applicable Call Date (and, pending such transfer, shall hold such
      amount for the benefit of the Warrant Holder in a segregated trust
      account).

            (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(h)(iii) or Section 7(f)(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(h)(iii) or Section 7(f)(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.

                                     B-3
<PAGE>

      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 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-4
<PAGE>

            (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 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.

   THIS CALL WARRANT IS ONLY TRANSFERABLE IF TRANSFERRED WITH OTHER CALL
   WARRANTS WHICH, TOGETHER WITH THIS CALL WARRANT,

                                     B-5
<PAGE>

   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."

      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

                                  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

                                     B-6
<PAGE>

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 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.

request in accordance herewith.

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,

      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,

      Depositor, and any Responsible Officer of the Trustee, and to apply to

      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.

      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.

      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.

      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.

      Warrant Agent in order to enable it to carry out or perform its duties
      hereunder.

      furnish to such Warrant Holder and/or a prospective purchaser designated
      by such Warrant Holder the information required to be delivered under

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

<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.

                                 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.

Warrant Agent Agreement shall be in writing and shall be delivered, or mailed

      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

      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

      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.

      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>

            Debenture-Backed Series 2003-14
            -------------------------------

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, BellSouth Telecommunications
Debenture-Backed Series 2003-14 Class A-1 Certificates and $_______________
aggregate Certificate Principal Balance of Corporate Backed Trust
Certificates, BellSouth Telecommunications Debenture-Backed Series 2003-14
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

                                      B-A-1
<PAGE>

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.

      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.

            THIS CALL WARRANT IS ONLY TRANSFERABLE IF TRANSFERRED
            WITH OTHER CALL WARRANTS WHICH, TOGETHER WITH THIS
            CALL WARRANT, 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

                                     B-A-2
<PAGE>

            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 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, BellSouth Telecommunications Debenture-Backed Series 2003-14
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
<PAGE>

  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.

            THIS CLASS A-2 CERTIFICATE IS ONLY TRANSFERABLE IF
            TRANSFERRED WITH OTHER CLASS A-2 CERTIFICATES WHICH,
            TOGETHER WITH THIS CERTIFICATE, HAVE AN AGGREGATE
            PRINCIPAL BALANCE EQUAL TO, OR GREATER THAN, $100,000.

            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 $125, (B) that each Class
      A-2 Certificate may only be transferred with other Class A-2
      Certificates which together have an aggregate principal balance equal
      to, or greater than, $100,000 and (C) 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

                                      C-3
<PAGE>

      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 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,
