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, (i) Class A-1
Certificates in a Certificate Principal Balance equal to the principal amount
of such additional Underlying Securities, (ii) Class A-2 Certificates having
an aggregate Amortizing Notional Balance in the same proportion to the
additional Class A-1 Certificates as exists with respect to the initial
aggregate Certificate Principal Balance of the Class A-1 Certificates and the
initial aggregate Amortizing Notional Balance of the Class A-2 Certificates
and (iii) Call Warrants related to such additional Class A-1 Certificates and
Class A-2 Certificates. 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. Upon the deposit of
additional Underlying Securities in the Trust, the Calculation Agent shall
revise and amend the Class A-2 Amortization Schedule in a manner that
maintains the intended yield on the Class A-2 Certificates.

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

                                      10

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 Amortizing Notional
Balance 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 Amortizing Notional Balance equal to the amount of Class
A-2 Certificates resold, assigned or transferred. In addition to the
foregoing, each prospective transferee of any Class A-2 Certificates in the
manner contemplated by clause (iii) above shall acknowledge, represent and
agree as follows:

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

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

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

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

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

                                      11
<PAGE>

          TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF THE SERIES
          SUPPLEMENT.

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

     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(c), 5(d) and 5(i),
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 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,
          accrued interest at 6.00% per annum, and to the holders of the Class
          A-2 Certificates, (x) accrued interest at the Class A-2 Rate and (y)
          the Class A-2 Notional Distribution Amount for the related
          Distribution Date, pro rata in proportion to their entitlements
          thereto.

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

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

               (2) second, to the holders of the Class A-1 Certificates, an
          amount equal to the Certificate Principal Balance of the Class A-1
          Certificates (the Class A-2 Certificates are not entitled to
          distributions from the principal portion of Available Funds).

                                      12
<PAGE>

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

          (iv) the Trustee will pay any Available Funds remaining in the
     Certificate Account after the distributions in clauses 5(a)(i) through
     5(a)(iii) above to the holders of the Class A-1 Certificates and Class
     A-2 Certificates pro rata in proportion to the interest rate on each such
     class of Certificates.

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) Interest shall continue to accrue on the Certificates during the
pendency of any Extension Period. Such interest shall be distributed to
Certificateholders, to the extent received by the Trustee, upon the completion
of the related Extension Period in accordance with the provisions of Section
5(a) hereof.

     (c) Notwithstanding the foregoing, if the Underlying Securities are
redeemed (including as a result of an optional redemption), 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 their maturity, the
Trustee shall apply Available Funds in the manner described in Section 5(h) 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 the principal amount of Underlying Securities
                 so redeemed, prepaid or liquidated plus accrued and unpaid
                 interest on the amount of Class A-1 Certificates redeemed in
                 connection with such principal payment;

          (iii)  third, to the holders of the Class A-2 Certificates, an
                 amount not to exceed the present value of all amounts that
                 would otherwise have been payable on the Class A-2
                 Certificates for the period from the date of such redemption
                 or prepayment to the Final Scheduled Distribution Date using
                 a discount rate of 6.00% per annum, assuming no
                 delinquencies, deferrals, redemptions or prepayments on the
                 Underlying Securities;

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

          (v)    fifth, 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.

                                      13
<PAGE>

     (d) 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 the holders of the Class A-2
Certificates in accordance with the ratio of the Class A-1 Allocation to the
Class A-2 Allocation.

     (e) 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 (2) Business Days
after the receipt of immediately available funds in accordance with Section
5(d) 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.

     (f) 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 (after deducting the costs incurred in connection
therewith) in accordance with Section 5(d) 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 or Amortizing Notional Balance, as applicable,
of the Certificates as follows: (x) the Certificate Principal Balance of the
Class A-1 Certificates will be reduced on a dollar-for-dollar basis and (y)
the Amortizing Notional Balance of the Class A-2 Certificates shall be reduced
in proportion to the reduction in the principal amount of Underlying
Securities held by the Trust.

     (g) Subject to Section 9(f) hereof, to the extent Available Funds are
insufficient to make any 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(h) hereof) on which sufficient funds are available to pay such
shortfall.

     (h) If a payment with respect to the Underlying Securities is made to the
Trustee (x) after the payment date of the Underlying Securities on which such
payment was due or (y) in connection with redemption, prepayment or
liquidation, 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, 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

                                      14
<PAGE>

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.

     (i) 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 ten 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.

     (j) As of the Closing Date, the aggregate Certificate Principal Balance
of the Class A-1 Certificates will equal the aggregate principal amount of
Underlying Securities deposited in the Trust. From time to time after the
Closing Date, the Certificate Principal Balance of the Class A-1 Certificates
will be reduced, dollar for dollar, in connection with any reduction in the
principal amount of Underlying Securities held by the Trust as a result of (i)
any distributions made to the holders of the Class A-1 Certificates in respect
of principal of the Underlying Securities or (ii) any surrender of
Certificates in connection with the consummation of an Optional Exchange. The
Amortizing Notional Balance of the Class A-2 Certificates will be reduced by
an aggregate amount equal to (x) the sum of all Class A-2 Notional
Distribution Amounts paid to Class A-2 Certificateholders and (y) the
aggregate amount of any reductions in the Amortizing Notional Balance of the
Class A-2 Certificates pursuant to Sections 5(c) and 5(f) hereof or in
connection with any surrender of Certificates in connection with the
consummation of an Optional Exchange.

     (k) (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 Class A-1 Certificateholders in the Underlying Securities
to be distributed shall be determined based on the then unpaid Certificate
Principal Balances of their respective Class A-1 Certificates and 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 Initial Amortizing Notional
Balances of their respective Class A-2 Certificates.

                                      15
<PAGE>

          (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(k))
     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 Initial Amortizing
     Notional Balances of their respective Class A-2 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 the lesser of (1) a pro
     rata share (based on the proportion of the Initial Amortizing Notional
     Balance of such holder's Class A-2 Certificates to the Initial Amortizing
     Notional Balance of the Class A-2 Certificates) of the principal amount
     of Underlying Securities remaining after the Trustee has allocated
     Available Funds in accordance with Sections 5(c)(i) and 5(c)(ii) hereof
     and (2) the present value of all amounts that would otherwise have been
     payable on the Class A-2 Certificates for the period from the date of
     such redemption or prepayment to the Final Scheduled Distribution Date
     using a discount rate of 6.00% per annum, assuming no delinquencies,
     deferrals, redemptions or prepayments on the Underlying Securities.

          (iii) The amount requested to be distributed pursuant to Section
     5(k)(i) or 5(k)(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(k)) 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(k), 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(e) or 5(i) hereof,
     as applicable and the proceeds thereof distributed to such Class A-1
     Certificateholder or Class A-2 Certificateholder.

                                      16
<PAGE>

          (iv) All decisions and determinations of the Calculation Agent
     pursuant to this Section 5(k) 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(c)(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 Call; Optional Exchange.

     (a) On (A) any Distribution Date, (B) any date on which the Underlying
Securities Issuer or an affiliate thereof consummates a tender offer for some
or all of the Underlying Securities or (C) any 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

                                      17
<PAGE>

     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 Underwriters but never distributed to investors) of the
     then outstanding Certificates.

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

          (vii) The provisions of Section 4.07 of the Standard Terms shall not
     apply to an Optional Exchange pursuant to this Section 7(b). This Section
     7(b) shall not provide any Person with a lien against, an interest in or
     a right to specific performance with respect to 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 Certificate Principal Balance or Amortizing
     Notional Balance, as the case may be, 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 August 2004, 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 February 15,
     2004 through, but excluding, the Closing Date by a fraction, the
     numerator of which

                                      18
<PAGE>

     shall be the number of Certificates being exchanged on such Optional
     Exchange Date and the denominator of which shall be the total number 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) [Reserved.]

(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 3 Business Days
     prior to the Call Date.

          (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 7(g)(iii) or Section
     7(h)(iii), 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.

                                      19
<PAGE>

          (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 Certificateholders or the Warrant Holders,
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 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 Certificateholders in accordance with 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 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

                                      20
<PAGE>

     would have been satisfied had all tendered Underlying Securities been
     accepted for payment and paid for); (B) each Warrant Holder's exercise
     shall be reduced by its share (proportionate to the amount specified in
     its exercise notice) of the amount of Underlying Securities not accepted
     for payment and paid for; (C) the Call Price shall be determined after
     giving effect to the reduction specified in clause (B); (D) the Call
     Warrants that relate to the reduction specified in clause (B) shall
     remain outstanding; and (E) the excess of the tender offer proceeds over
     the Call Price shall be allocated in proportion to the amount of Call
     Warrants deemed exercised as set forth in clause (A) above or, if the
     Call Price exceeds the tender offer proceeds the amount of such excess
     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 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.

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

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

          (iii) The Call Price shall be deducted from the redemption proceeds
and paid to Certificateholders in accordance with 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

                                      21
<PAGE>

in clause (B) shall remain outstanding; and (E) the excess of the redemption
proceeds over the Call Price shall be allocated in proportion to the amount of
Call Warrants deemed exercised as set forth in clause (A) above.

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

     Section 8. Notices of Events of Default.

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

     Section 9. Miscellaneous.

     (a) The provisions of Section 4.04, Advances, of the Standard Terms shall
not apply to the Goldman Sachs Capital I Securities-Backed Series 2004-4
Certificates.

     (b) The provisions of Section 4.07, Optional Exchange, of the Standard
Terms shall not apply to the Goldman Sachs Capital I Securities-Backed Series
2004-4 Certificates.

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

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

     (e) The provisions of Section 3.07(d) of the Standard Terms shall not
apply to the Goldman Sachs Capital I Securities-Backed Series 2004-4
Certificates.

     (f) If the Trustee has not received payment with respect to a Collection
Period on the Underlying Securities on or prior to the related Distribution
Date, such distribution will be made promptly upon receipt of such payment. No
additional amounts shall accrue on the Certificates or be owed to
Certificateholders as a result of such delay; provided, however, that any
additional interest owed and paid by the Underlying Securities Issuer as a
result of such delay shall be paid to the Class A-1 Certificateholders and
Class A-2 Certificateholders pro rata in proportion to their respective
entitlements to such delayed payments.

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

                                      22
<PAGE>

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

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

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

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

     (l) In relation to Section 7.01(f) of the Standard Terms, any periodic
reports filed by the Trustee pursuant to the Exchange Act in accordance with
the customary practices of the Depositor, need not contain any independent
reports. Notwithstanding anything to the contrary, any references in such
reports (or any exhibits attached thereto) to "servicing obligations" of the
Trustee shall be limited to the obligations of the Trustee expressly set forth
in the Trust Agreement.

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

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

                                      23
<PAGE>

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.

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

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

     (q) 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.

     (r) The provisions of Section 2.01(d)(iii) of the Standard Terms shall
not apply to the Goldman Sachs Capital I Securities-Backed Series 2004-4
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) The Trustee shall appoint a firm of independent certified public
accountants to determine that the asset of the Trust exists at the balance
sheet date and that such asset of the Trust reflects the correct value on that
date and 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 procedures to be agreed upon between the
Depositor and such independent certified public accountants based on
established or stated criteria as set forth in the professional

                                      25
<PAGE>

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.

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

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

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

     Section 13. Sale of Underlying Securities. 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

                                      26
<PAGE>

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 Underlying
Securities Trust Agreement; Optional Exchange.

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

                                      27
<PAGE>

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 Underlying Securities Trust
Agreement 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 applicable Underlying
Securities Trustee to declare the unpaid principal amount of the Underlying
Securities and any accrued and unpaid interest thereon to be due and payable.

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

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

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

                                      28
<PAGE>

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

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

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

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

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

                           (REVERSE OF CERTIFICATE)

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

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

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

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

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 $100,000 and in integral multiples of $1 in excess thereof.

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

          WHEREAS, the Depositor created Corporate Backed Trust Certificates,

                           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-2
<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 an Initial Amortizing Notional Balance equal to $25
     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. 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-3
<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 7(g)(iii) or Section 7(h)(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, 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 7(g)(iii) or Section 7(h)(iii), as
     applicable, of the Series Supplement, or

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

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

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

     Section 1.3 Cancellation and Destruction of Call Warrants. All Call
Warrants surrendered to the Warrant Agent for the purpose of exercise (in
whole or in part) pursuant to

                                     B-4
<PAGE>

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 amount of Class A-2 Certificates callable by Call Warrants shall
equal the outstanding amount 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 Class A-1 Call Warrants shall consist initially of 3,400,000
     Call Warrants, each relating to to $25 principal amount of Class A-1
     Certificates. The Class A-2 Call Warrants shall consist initially of
     146,240 Call Warrants, each relating to to $25 Initial Amortizing
     Notional Balance of Class A-2 Certificates.

          (b) 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

                                     B-5
<PAGE>

     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.

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

          (d) 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

                                     B-6
<PAGE>

     REPRESENTED HEREBY MAY BE TRANSFERRED ONLY IN COMPLIANCE WITH THE
     CONDITIONS SPECIFIED IN THE CALL WARRANTS.

     THESE CALL WARRANTS ARE ONLY TRANSFERABLE IF TRANSFERRED WITH OTHER CALL
     WARRANTS WHICH, TOGETHER WITH THESE CALL WARRANTS, REPRESENT THE RIGHT TO
     CALL CLASS A-2 CERTIFICATES HAVING AN AGGREGATE INITIAL AMORTIZING
     NOTIONAL 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
Certificated Call Warrant or portion thereof, the Warrant Holder will give
five (5) Business Days (or such lesser period acceptable to the Warrant Agent)
prior written notice to the Warrant Agent of such Warrant Holder's intention
to effect such transfer.

                                  ARTICLE IV

               REGISTRATION AND TRANSFER OF CALL WARRANTS, ETC.

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

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

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

          Section 4.2 Transfer and Exchange of Call Warrants. (a) No Call
Warrant or any beneficial interest therein may be offered, resold, assigned or
otherwise transferred (including by pledge or hypothecation) unless such
offer, resale, assignment or transfer is to a qualified

                                     B-7
<PAGE>

institutional buyer (a "QIB"), as such term is defined in Rule 144A
promulgated under the Securities Act ("Rule 144A"), in accordance with Rule
144A, and in accordance with any applicable securities laws of any state of
the United States and other jurisdictions. In addition, each Call Warrant
relating to a Class A-2 Certificate may only be transferred with other Call
Warrants relating to Class A-2 Certificates, which together represent the
right to call Class A-2 Certificates having an aggregate Initial Amortizing
Notional 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. In addition to the foregoing, 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 Certificated 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 Certificated 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

                                     B-8
<PAGE>

indemnity bond in such reasonable amount as the Warrant Agent may determine,
or, in the case of any such mutilation, upon the surrender of such Call
Warrant for cancellation to the Warrant Agent, the Warrant Agent shall execute
and deliver, and cause the Trustee, on behalf of the Trust, to execute and
deliver, in lieu thereof, a new Call Warrant of like tenor bearing a number
not contemporaneously outstanding.

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

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

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

     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

                                     B-11
<PAGE>

          (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, an Assistant
     Treasurer, its Secretary or an Assistant Secretary of the Depositor, and

     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

     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.

     action as the Warrant Agent may consider proper, whether with or without
     such indemnity. The Warrant Agent shall promptly notify the Depositor and

     by such Warrant Holder the information required to be delivered under
     Rule 144A(d)(4) under the Securities Act, to the extent that such
     information is in the possession of the Warrant Agent.

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

provided that no such resignation or discharge shall become effective until a
successor Warrant Agent shall have been appointed hereunder. The Depositor may

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

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

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
or modify any other provisions with respect to matters or questions arising
under the Call Warrant which shall not adversely affect in any material
respect the interests of the Warrant Holder or any holder of a Certificate;

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

                                     B-14
<PAGE>

     Certificates evidencing not less than 100% of the aggregate Voting Rights
     of such affected Certificates and 100% of the affected Warrant Holders or
     (iii) reduce the percentage of aggregate Voting Rights required by (i) or
     (ii) without the consent of the holders of all such affected
     Certificates. Notwithstanding any other provision of this Warrant Agent
     Agreement, this Section 7.4(b) shall not be amended without the consent
     of 100% of the affected Warrant Holders.

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

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

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

IN ACCORDANCE WITH, AND THE RIGHTS OF THE PARTIES SHALL BE GOVERNED BY, THE
LAW OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF

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

     Section 7.9 Nonpetition Covenant; No Recourse. Each of (i) the Warrant
Holder by its acceptance thereof, and (ii) the Warrant Agent agrees, that it
shall not (and, in the case of the Warrant Holder, that it shall not direct
the Warrant Agent to), until the date which is one year and one day after the
payment in full of the Certificates and all other securities issued by the
Trust, the Depositor or entities formed, established or settled by the

          Re:  Corporate Backed Trust Certificates, Goldman Sachs Capital I
               Securities-Backed Series 2004-4
               -------------------------------

Ladies and Gentlemen:

          In connection with its proposed purchase of Call Warrants (the "Call
Warrants") which represent the right to call $______________ aggregate
certificate principal balance of Corporate Backed Trust Certificates, Goldman
Sachs Capital I Securities-Backed Series 2004-4 Class A-1 Certificates and
$_______________ aggregate amortizing notional balance of Corporate Backed
Trust Certificates, Goldman Sachs Capital I Securities-Backed Series 2004-4
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

                                      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 OR IN THE SERIES SUPPLEMENT.

               THESE CALL WARRANTS ARE ONLY TRANSFERABLE IF TRANSFERRED WITH
               OTHER CALL WARRANTS WHICH, TOGETHER WITH THESE CALL WARRANTS,
               REPRESENT THE RIGHT TO CALL CLASS A-2 CERTIFICATES HAVING AN
               AGGREGATE INITIAL AMORTIZING NOTIONAL 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 (B) the Purchaser causes the proposed
transferee to provide to the Depositor and the Trustee such documentation as
may be required pursuant to Section 4.2 of the Warrant Agent Agreement,
including, if required, a letter substantially in the form hereof, or such
other written statement as the Depositor shall reasonably prescribe.

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

                                     A-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
Amortizing Notional Balance of Class A-2 Certificates (the "Class A-2
Certificates") representing an interest in the Corporate Backed Trust
Certificates, Goldman Sachs Capital I Securities-Backed Series 2004-4 Trust
(the "Trust"), the undersigned, by executing this letter (the "Purchaser")
confirms that:

     1. Reference is made to the private placement memorandum, dated February
13, 2004, including the schedules, exhibits and annexes, if any, thereto, as
supplemented or amended to the date hereof (the "Memorandum"), relating to the
Class A-2 Certificates. Capitalized terms used herein that are not otherwise
defined shall have the meanings ascribed thereto in the Memorandum. The
Purchaser has received a copy of the Memorandum and such other information as
the Purchaser deems necessary in order to make its investment decision and the
Purchaser has been provided the opportunity to ask questions of, and receive
answers from, the Depositor and the Initial Purchaser, concerning the terms
and conditions of the offering described in the Memorandum. The Purchaser has
received and understands the information discussed above and 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 the Memorandum and in the other written information, if
any, discussed above. The Purchaser acknowledges that it has read and agreed
to the matters stated on pages 2 through 4 of such Memorandum and the
information under the heading "Transfer

                                     C-1
<PAGE>

Restrictions." 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.

     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") (as defined in
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,
other than the information contained in the Memorandum, which has been
delivered to the Purchaser and upon which the Purchaser is relying in making
an investment decision with respect to the Class A-2 Certificates.
Accordingly, the Purchaser acknowledges that no representation or warranty is
made by the Depositor or the Initial Purchaser as to the accuracy or
completeness of such materials.

     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

                                     C-2

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:

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

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

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

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

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

                                      Very truly yours,

                                           ------------------------------
                                           Name:
                                           Title:

                                     C-4EXHIBIT 10.9(o)

                              EMPLOYMENT AGREEMENT

     This Agreement ("the Agreement") dated as of the 1st day of August, 2003
(the "Effective Date"), is by and between CryoLife, Inc., a Florida corporation
("CryoLife") and Thomas J. Lynch, J.D., Ph.D. (the "Employee").

                                   WITNESSETH:

     WHEREAS, the Board of Directors of CryoLife (the "Board"), has determined
that it is in the best interests of CryoLife and its shareholders to enter into
this Employment Agreement in order to assure the Employee of CryoLife's
commitment and, in so doing, to motivate the Employee to continue in Employee's
dedicated service to CryoLife,

     WHEREAS, in order to accomplish these objectives, the Board has caused
CryoLife to enter into this Agreement.

     NOW, THEREFORE, in consideration of the premises, the promises hereinafter
set forth and other good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledges, it is hereby agreed as follows:

          1. Employment.

          (a) CryoLife hereby employs Employee in the capacity of Vice
President, Regulatory Affairs and Quality Assurance and Employee hereby accepts
such duties as are customarily performed and exercised by such officer subject
to the supervision of the President of CryoLife. The duties of Employee shall
include those duties more specifically described on Exhibit A attached hereto
together with such additional duties as are assigned by the President of
CryoLife.

          (b) CryoLife agrees to continue the Employee in its employ, and the
Employee hereby agrees to remain in the employ of CryoLife subject to the terms
and conditions of this Agreement, for the period commencing on the Effective
Date and ending on the second anniversary of such date (the "Employment
Period"). Unless either party elects not to extend the term of this Agreement by
so notifying the other in writing at least 30 days prior to the first
anniversary of the Effective Date, the Employment Period shall automatically
extend for an additional one year.

<PAGE>

          2. Employment Duties.

          (a) During the Employment Period, and excluding any periods of
vacation and sick leave to which the Employee is entitled, the Employee agrees
to devote reasonable attention and time to the business and affairs of CryoLife
and, to the extent necessary to discharge the responsibilities assigned to the
Employee hereunder, to use the Employee's reasonable best efforts to perform
faithfully and efficiently such responsibilities.

          (b) During the Employment Period, the Employee will not, without the
prior written consent of CryoLife, directly or indirectly other than in the
performance of the duties hereunder, render services of a business, professional
or commercial nature to any other person or firm, whether for compensation or
otherwise, except with respect to any noncompetitive family businesses of the
Employee for which the rendering of such services will not have an adverse
effect upon Employee's performance of his duties and obligations hereunder.

          3. Compensation, Benefits and Business Expenses.

          (a) For all services which Employee renders to CryoLife or any of its
subsidiaries or affiliates during the term hereof, CryoLife agrees to pay the
Employee the salary and bonus compensation as set by the Compensation Advisory
Committee of the Board of Directors. Employee's salary at the Effective Date is
set forth on Exhibit A.

          (b) CryoLife shall pay all reasonable expenses incurred by the
Employee directly related to performance of his responsibilities and duties for
CryoLife hereunder. Employee shall submit to CryoLife statements that justify in
reasonable detail all reasonable expenses so incurred. Subject to such audits as
CryoLife may deem necessary, CryoLife shall reimburse Employee the full amount
of any such expenses advanced by Employee.

          (c) Employee shall be entitled to a vacation each year of his
employment with CryoLife, according to the standard vacation policy, as well as
insurance and other employment benefits, as more particularly described on
Exhibit A. Vacations not taken shall be cumulative and carried over to a
subsequent year.

          4. Termination of Employment.

          (a) Disability or Death. If CryoLife determines in good faith that the
Disability of the Employee has occurred during the Employment Period (pursuant
to the definition of Disability set forth below), it may give to the Employee
written notice in accordance with Section 11(b) of this Agreement of its
intention to terminate the Employee's employment. In such event, the Employee's
employment with CryoLife shall terminate effective on the 30th day after receipt
of such notice by the Employee (the "Disability Effective Date"), provided that,
within the 30 days after such receipt, the Employee shall not have returned to
full-time performance of the Employee's duties. For purposes of this Agreement,
"Disability" shall mean the absence of the Employee from the Employee's duties

                                       2
<PAGE>

with CryoLife on a full-time basis for 180 consecutive business days as a result
of incapacity due to mental or physical illness which is determined to be total
and permanent by a physician selected by CryoLife or its insurers and acceptable
to the Employee or the Employee's legal representative. The Employee's
employment shall terminate automatically upon the Employee's death during the
Employment Period.

          (b) Cause. CryoLife may terminate the Employee's employment during the
Employment Period for Cause. For purposes of this Agreement, "Cause" shall mean:

               (i) the willful and continued failure of the Employee to perform
substantially the Employee's duties with CryoLife (other than any such failure
resulting from incapacity due to physical or mental illness), after a written
demand for substantial performance is delivered to Employee by the Board or the
Chief Executive Officer of CryoLife which specifically identifies the manner in
which CryoLife believes that the Employee has not substantially performed the
Employee's duties, or

               (ii) the willful engaging by the Employee in illegal conduct or
gross misconduct which is materially and demonstrably injurious to CryoLife.

For purposes of this provision, no act or failure to act, on the part of the
Employee, shall be considered "willful" unless it is done, or omitted to be
done, by the Employee in bad faith or without reasonable belief that the
Employee's action or omission was in the best interests of CryoLife. Any act, or
failure to act, based upon authority given pursuant to a resolution duly adopted
by the Board or upon the instructions of the Chief Employee Officer or a senior
officer of CryoLife or based upon the advice of counsel for CryoLife shall be
conclusively presumed to be done, or omitted to be done, by the Employee in good
faith and in the best interests of CryoLife.

          (c) Notice of Termination. Any termination by CryoLife for Cause,
shall be communicated by Notice of Termination to the other party hereto given
in accordance with Section 11(b) of this Agreement. For purposes of this
Agreement, a "Notice of Termination" means a written notice which (i) indicates
the specific termination provision in this Agreement relied upon, (ii) to the
extent applicable, sets forth in reasonable detail the facts and circumstances
claimed to provide a basis for termination of the Employee's employment under
the provision so indicated and (iii) if the Date of Termination (as defined
below) is other than the date of receipt of such notice, specifies the
termination date (which date shall be not more than 30 days after the giving of
such notice). The failure by CryoLife to set forth in the Notice of Termination
any fact or circumstance which contributes to a showing of Cause shall not waive
any right of CryoLife hereunder or preclude CryoLife from asserting such fact or
circumstance in enforcing CryoLife's rights hereunder.

          (d) Date of Termination. "Date of Termination" means (i) if the
Employee's employment is terminated by CryoLife for Cause, the date of receipt
of the Notice of Termination, or any later date specified therein, as the case
may be, (ii) if the Employee's employment is terminated by CryoLife other than
for Cause or Disability, the Date of Termination shall be the date on which
CryoLife notifies the Employee of such termination and (iii) if the Employee's
employment is terminated by reason of death or Disability, the Date of
Termination shall be the date of death of the Employee or the Disability
Effective Date, as the case may be.

                                       3

          5. Obligations of CryoLife upon Termination.

          (a) Other Than for Cause, Death or Disability. If, during the
Employment Period, CryoLife shall terminate the Employee's employment other than
for Cause, Death or Disability, then CryoLife shall pay to Employee as severance
compensation an amount equal to $240,000.00. Such payment shall be in addition
to sums due to Employee through the Date of Termination and shall be subject to
normal withholding requirements of CryoLife. Payment of the amount shall be made
in one lump sum payment or in six equal monthly installments as directed by the
Employee.

          (b) Death. If the Employee's employment is terminated by reason of the
Employee's death during the Employment Period, this Agreement shall terminate
without further obligations to the Employee's legal representatives under this
Agreement, other than for payment of obligations accruing through the Date of
Termination.

          (c) Disability. If the Employee's employment is terminated by reason
of the Employee's Disability during the Employment Period, this Agreement shall
terminate without further obligations to the Employee, other than for payment
obligations accruing through the Date of Termination.

          (d) Cause. If the Employee's employment shall be terminated by
CryoLife for Cause during the Employment Period, this Agreement shall terminate
without further obligations to the Employee other than the obligation to pay to
the Employee his or her salary through the Date of Termination.

          6. Non-exclusivity of Rights. Nothing in this Agreement shall prevent
or limit the Employee's continuing or future participation in any plan, program,
policy or practice provided by CryoLife or any of its affiliated companies and
for which the Employee may qualify, nor shall anything herein limit or otherwise
affect such rights as the Employee may have under any contract or agreement with
CryoLife or any of its affiliated companies. Amounts which are vested benefits
or which the Employee is otherwise entitled to receive under any plan, practice
or program of or any contract or agreement with CryoLife or any of its
affiliated companies at or subsequent to the Date of Termination shall be
payable in accordance with such plan, policy, practice or program or contract or
agreement except as explicitly modified by this Agreement.

          7. Full Settlement. In no event shall the Employee be obligated to
seek other employment or take any other action by way of mitigation of the
amounts payable to the Employee under any of the provisions of this Agreement
and such amounts shall not be reduced whether or not the Employee obtains other
employment. CryoLife agrees to pay as incurred, to the full extent permitted by
law, all legal fees and expenses which the Employee may reasonably incur as a
result of any contest (regardless of the outcome thereof) by CryoLife, the
Employee or others of the validity or enforceability of, or liability under, any
provision of this Agreement.

                                       4
<PAGE>

          8. Limitation or Expansion of Benefits.

          (a) Anything in this Agreement to the contrary notwithstanding, in the
event it shall be determined that any benefit, payment or distribution by the
Company to or for the benefit of the Employee (whether payable or distributable
pursuant to the terms of this Agreement or otherwise) (a "Payment") would, if
paid, be subject to the excise tax imposed by Section 4999 of the Internal
Revenue Code of 1986, as amended (the "Code"; such excise tax, the "Excise
Tax"), then the Payment shall be reduced to the extent necessary of avoid the
imposition of the Excise Tax. The Employee may select the Payment to be limited
or reduced.

          (b) All determinations required to be made under this Section 8,
including whether an Excise Tax would otherwise be imposed and the assumptions
to be utilized in arriving at such determination and the value of the maximum
amount payable without imposition of the Excise Tax, shall be made by the
certified public accounting firm regularly engaged by the Company (the
"Accounting Firm") which shall provide detailed supporting calculations both to
the Company and the Employee within 30 business days of the receipt of notice
from the Employee that a Payment is due to be made, or such earlier time as is
requested by the Company. All fees and expenses of the Accounting Firm shall be
borne solely by the Company. Any determination by the Accounting Firm shall be
binding upon the Company and the Employee. As a result of the uncertainty in the
application of Section 4999 of the Code at the time of the initial determination
by the Accounting Firm hereunder, it is possible that Payments hereunder will
have been unnecessarily limited by this Section 8 ("Underpayment"), consistent
with the calculations required to be made hereunder. The Accounting Firm shall
determine the amount of the Underpayment that has occurred and any such
Underpayment shall be paid by the Company to or for the benefit of the Employee.

          (c) The provisions of this Section 8 shall not apply unless and until
amounts become payable to Employee pursuant to Section 5(a) hereof.

          9. Confidential Information. The Employee and CryoLife are parties to
one or more separate agreements respecting confidential information, trade
secrets, inventions and non-competition (collectively, the "IP Agreements"). The
parties agree that the IP Agreements shall not be superceded or terminated by
this Agreement and shall survive any termination of this Agreement.

          10. Successors.

          (a) This Agreement is personal to the Employee and without the prior
written consent of CryoLife shall not be assignable by the Employee otherwise
than by will or the laws of descent and distribution. This Agreement shall inure
to the benefit of and be enforceable by the Employee's legal representatives.

          (b) This Agreement shall inure to the benefit of and be binding upon
CryoLife and its successors and assigns.

                                       5
<PAGE>

          (c) CryoLife will require any successor (whether direct or indirect,
by purchase, merger, consolidation or otherwise) to all or substantially all of
the business and/or assets of CryoLife to assume expressly and agree to perform
this Agreement in the same manner and to the same extent that CryoLife would be
required to perform it if no such succession had taken place. As used in this
Agreement, "CryoLife" shall mean CryoLife as hereinbefore defined and any
successor to its business and/or assets as aforesaid which assumes and agrees to
perform this Agreement by operation of law, or otherwise.

          11. Miscellaneous.

          (a) This Agreement shall be governed by and construed in accordance
with the laws of the State of Georgia, without reference to principles of
conflict of laws. The captions of this Agreement are not part of the provisions
hereof and shall have no force and effect. This Agreement may not be amended or
modified otherwise than by a written agreement executed by the parties hereto or
their respective successors and legal representatives.

          (b) All notices and other communications hereunder shall be in writing
and shall be given by hand delivery to the other party or by registered or
certified mail, return receipt requested, postage prepaid, addressed as follows:

          (d) CryoLife may withhold from any amounts payable under this
Agreement such Federal, state, local or foreign taxes as shall be required to be
withheld pursuant to any applicable law or regulation.
