                                      6
<PAGE>

Series 2001-3." The Certificates shall consist of the Class A-1 Certificates
and the Class A-2 Certificates (together, the "Certificates").

     (a) The Class A-1 Certificates shall be held through the Depository in
book-entry form and shall be substantially in the form attached hereto as
Exhibit A-1. The Class A-1 Certificates shall be issued in denominations of
$25. The Class A-2 Certificates shall be issued as uncertificated securities
having the rights and interests set forth herein and shall be issued in a
single denomination equal to their initial Certificate Principal Balance.
Except as provided in the Standard Terms and in paragraph (d) in this Section,
the Trust shall not issue additional Certificates or incur any indebtedness.
The holder of the Class A-2 Certificates shall for so long as such
Certificates are outstanding be the Rights Holders and the transferability of
the Class A-2 Certificates shall be subject to and governed by the provisions
of the Warrant Agent Agreement. In the event that there is more than one
Rights Holder, the Class A-2 Certificates shall be deemed held by each Rights
Holder, with each Rights Holder owning its pro rata share (based on the ratio
of the total number of Call Warrants held by such Rights Holder to the total
number of Call Warrants outstanding) of the Class A-2 Certificates. Section
5.02 of the Standard Terms shall not apply to the Class A-2 Certificates.

     (b) The Class A-1 Certificates have an initial aggregate Certificate
Principal Amount of $25,407,700.00. The Class A-2 Certificates have an initial
Certificate Principal Amount of $592,300.00.

     (c) The holders of the Class A-1 Certificates will be entitled to receive
on each Distribution Date the interest, if any, received on the Underlying
Securities, to the extent necessary to pay interest at a rate of 7.125% per
annum on the outstanding Certificate Principal Amount of the Class A-1
Certificates. The Class A-2 Certificates do not bear interest. On December 1,
2001, the Trustee will pay to the Depositor the amount of interest accrued on
the Underlying Securities from June 1, 2001 to but not including the Closing
Date, to the extent such amount is paid on the Underlying Securities on such
date (and to the extent that the amount of such interest accrued on the
Underlying Securities from the Closing Date to but not including December 1,
2001 has been fully paid).

     (d) The Depositor may sell to the Trustee additional Underlying
Securities on any date hereafter upon at least 3 Business Days notice to the
Trustee and upon (i) satisfaction of the Rating Agency Condition and (ii)
delivery of an Opinion of Counsel to the effect that the sale of such
additional Underlying Securities will not materially increase the likelihood
that the Trust would fail to qualify as a grantor trust under the Code or
cause the Trust to be required to register as an "investment company" as such
term is defined in the Investment Company Act of 1940. 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
or its order Class A-1 Certificates in a Certificate Principal Amount, that is
an integral multiple of $25.00 and is at least equal to 97.721923% of the
principal amount of such additional Underlying Securities, and without further
action the Certificate Principal Amount of the Class A-2 Certificates shall
increase by the difference between the principal amount of such additional
Underlying Securities and the increase in the Certificate Principal Amount of
the Class A-1 Certificates. Any such additional Certificates authenticated and
delivered or otherwise issued shall have the same terms

                                      7
<PAGE>

and rank pari passu with the corresponding classes of Certificates previously
issued in accordance with this Series Supplement.

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

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

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

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

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

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

               (2) second, to the holders of the Class A-1 Certificates,
          interest accrued and unpaid on such Class; and

               (3) third, to the Depositor for the payment of Trust expenses
          but in an amount not to exceed $9,701 in any calendar year; and

          (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 Certificateholders
          representing 100% of the Voting Rights with respect thereto; and

               (2) second, to the holders of the Class A-1 Certificates until
          the Certificate Principal Amount thereof has been reduced to zero;
          and

               (3) third, to the holders of the Class A-2 Certificates until
          the Certificate Principal Amount thereof has been reduced to zero.

     (b) Notwithstanding any other provision hereof (other than Section 3(c))
if the Underlying Securities are redeemed, prepaid or liquidated in whole or
in part for any reason (including, without limitation, an Event of Default)
other than at their maturity, the Trustee shall apply Available Funds on the
related Distribution Date (or Special Distribution Date, if applicable) in the
same order of priority as is set forth in Section 5(a). In the event of any
payment on any such date of less than all of the outstanding Class A-1
Certificates, the Class A-1 Certificates to be retired will be selected by the
Trustee or DTC by lot.

                                      8
<PAGE>

     (c) Notwithstanding any other provision hereof, in the event of the
occurrence of (i) a payment default on the Underlying Securities or (ii) an
acceleration of the date of maturity of the Underlying Securities in
connection with a default thereon, the holders of the Certificates
representing a majority of the Voting Rights on the Class A-1 Certificates
will be entitled to direct the Trustee in any such proceeding or direct the
Trustee to sell the Underlying Securities. If the Trustee is directed to sell
the Underlying Securities, the Trustee shall solicit bids for the sale of the
Underlying Securities with settlement thereof on or before the third (3rd)
Business Day after such sale from three leading dealers in the relevant
market. Any of the following dealers (or their successors) shall be deemed to
qualify as leading dealers: (1) Credit Suisse First Boston Corporation, (2)
Goldman, Sachs & Co., (3) Lehman Brothers Inc., (4) Merrill Lynch, Pierce,
Fenner & Smith Incorporated, (5) Bear, Stearns & Co. Inc., and (6) Salomon
Smith Barney 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 such sale or
of an acceleration and a corresponding payment on the Underlying Securities,
the Trustee shall distribute the proceeds to the Certificateholders no later
than two Business Days after the receipt of immediately available funds in
accordance with Section 5(b) hereof.

     (d) In the event that 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 Depositary, or for any Certificates which are not
then held by DTC or any other depository, directly to the registered holders
of the Certificates then outstanding and unpaid. Such notice shall state that,
not later than 30 days after the receipt of such moneys or other property, the
Trustee will 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 the
priorities of distribution established pursuant to Section 5(a) 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 will be deemed to reduce
the principal amount of Certificates on a dollar-for-dollar basis.

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

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

                                      9
<PAGE>

     (g) [Reserved].

     (h) Notwithstanding Section 3.12 of the Standard Terms, if the Underlying
Securities Guarantor ceases to file periodic reports as required under the
Exchange Act, the Depositor shall within 5 Business Days instruct the Trustee
to sell the Underlying Securities and distribute the proceeds of such sale to
the Certificateholders in accordance with the order of priority set forth in
Section 5(a) provided, however, the Depositor shall not instruct the Trustee
to distribute or sell the Underlying Securities pursuant to this clause unless
the Underlying Securities Guarantor has either (x) stated in writing that it
intends permanently to cease filing reports required under the Exchange Act or
(y) failed to file any required reports for one full calendar year.

     Section 6. Trustee's Fees. (a) As compensation for its services
hereunder, the Trustee shall be entitled to the Trustee Fee as agreed to
separately in a fee agreement among the Depositor and the Trustee. 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 Certificateholders of each of Class A-1 Certificates then
outstanding have voted to require 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. Redemption Upon Exercise of Call Warrants.

     (a) [Reserved].

     (b) On any Call Date, Class A-1 Certificates shall be redeemed at par
plus accrued and unpaid interest on the Class A-1 Certificates upon receipt by
the Trustee of the Call Price on or prior to such Call Date. On any Call Date
on which one or more of the Rights Holders duly exercises less than all of the
Call Warrants then outstanding, the Class A-1 Certificates shall be redeemed
in part and the Class A-1 Certificates to be redeemed will be selected by the
Trustee or DTC by lot and will be paid for on the Call Date.

          (i) Any Rights Holder, in order for it to exercise its Call Rights
     in whole or in part, shall provide notice to the Trustee (a "Call
     Request") no more than 60 or less than 35 days prior to any Call Date,
     that it is exercising its Call Rights on such Call Date, indicating the
     principal amount of Underlying Securities as to which such call will be
     exercised.

<PAGE>

          (ii) Deliveries of the Underlying Securities purchased on any Call
     Date by a Rights Holder (the "Purchaser") will only be made against
     payment by the Purchaser of the Call Price with respect to such
     Underlying Securities in immediately available funds. Such payment must
     occur no later than 10:00 a.m. New York City time on the Call Date. In
     the event that the Purchaser fails to make such payment by such time (a
     "Purchase Default"), the sale shall be voided and the exercise of Call
     Rights will be deemed not to be effective with respect to such Call Date,
     and the Certificates and the Call Rights shall continue to remain
     outstanding. Subject to receipt of the Call Price as aforesaid on any
     Call Date, the Trustee shall pay the corresponding redemption price set
     forth in clause (b), above, to the Class A-1 Certificateholders on such
     Call Date.

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

          (iv) The Trustee shall not be obligated to determine whether an
     exercise of Call Rights 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.

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

          (vi) The Rights Holder shall initially be the Depositor and such
     Call Rights may be transferred to one or more holders. However, the
     Trustee is under no obligation to recognize any notice of transfer unless
     it is signed by the transferor and the transferee.

          (vii) Any exercise of Call Rights by a Rights Holder must be in a
     minimum principal amount of Underlying Securities equal to $500,000 and
     integral multiples of $500,000 in excess thereof.

          (viii) The exercise of a Call Warrant shall constitute the
     redemption by the Trust of the Class A-2 Certificates deemed held in
     connection with such Call Warrant by the exercising Rights Holder;
     provided, that no payment shall be made on such Class A-2 Certificate by
     the Trust in connection with such redemption.

          (ix) Any exercise of Call Rights by a Rights Holder must include a
     certification by the Rights Holder that it is solvent as of the Call
     Date.

     Section 8. Events of Default.

          Within 30 days of the occurrence of an Event of Default actually
known to the Trustee, the Trustee will give notice to the Certificateholders
and the Rating Agency, transmitted by mail, of all such uncured or unwaived
Events of Default known to it. 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 from the Certificateholders 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 Series 2001-3 Certificates.

the Underlying Securities.

     (e) The provisions of Section 3.07(d) of the Standard Terms shall not
apply to the Series 2001-3 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 Certificateholders, pro rata in
proportion to their respective entitlements to interest.

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

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

     (i) Notwithstanding anything in the Trust Agreement to the contrary, the
Trustee may be removed upon 60 days prior written notice delivered by the
holders of Class 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.

                                      12
<PAGE>

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

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

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

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

     Section 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 on or an acceleration or other early payment of the
Underlying Securities and the distribution in full of all amounts due to the
Class A-1 and Class A-2 Certificateholders; (ii) the payment in full of the
Class A-1 Certificates upon exercise of all of the issued Call Rights under
Section 7(b); and (iii) 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 Section 5(d) hereof, the Liquidation
Proceeds, if any, shall be deposited into the Certificate Account for
distribution to the Class A-1 and Class A-2 Certificateholders pursuant to
Section 5(a). The Trustee shall only deliver the Underlying Securities to the
purchaser of such Underlying Securities against payment in same day funds
deposited into the Certificate Account.

     Section 14. Amendments. Notwithstanding anything in the Trust Agreement
to the contrary, in addition to the other restrictions on modification and
amendment contained therein, the Trustee shall not enter into any amendment or
modification of the Trust Agreement which would adversely affect in any
material respect the interests of the holders of any class of Certificates
without the consent of the holders of 100% of such class of Certificates;
provided, however, that no such amendment or modification will be permitted
which would alter the status of the Trust as a grantor trust for federal
income tax purposes. Further, no amendment shall be permitted which would
adversely affect in any material respect the interests of the Class A-1
Certificateholders unless the Rating Agency Condition is satisfied with
respect to such amendment.

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

                                      15
<PAGE>

consent to or vote to accept such amendment, modification, waiver or
solicitation. The Trustee shall consent or vote, or refrain from consenting or
voting, in the same proportion (based on the relative outstanding principal
balances of the Certificates) as the Certificates 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, after weighing
the votes of the Certificateholders; provided, however, that, notwithstanding
anything in the Trust Agreement to the contrary, the Trustee shall at no time
vote on or consent to any matter (i) unless such vote or consent would not
(based on an opinion of counsel) alter the status of the Trust as a grantor
trust for federal income tax purposes or result in the imposition of tax upon
the Certificateholders, (ii) which would alter the timing or amount of any
payment on the Underlying Securities, including, without limitation, any
demand to accelerate the Underlying Securities, except in the event of a
default under the Underlying Securities or an event which with the passage of
time would become an event of default under the Underlying Securities and with
the unanimous consent of all outstanding Class A-1 Certificateholders and the
Class A-2 Certificateholders, or (iii) which would result in the exchange or
substitution of any of the outstanding Underlying Securities pursuant to a
plan for the refunding or refinancing of such Underlying Securities except in
the event of a default under the Indenture and only with the consent of
Certificateholders representing 100% of the Voting Rights with respect
thereto. The Trustee shall have no liability for any failure to act resulting
from Certificateholders' late return of, or failure to return, directions
requested by the Trustee from the Certificateholders.

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

          If an event of default under the Indenture occurs and is continuing,
and if directed by Class A-1 Certificateholders representing 51% or more of
the Voting Rights with respect thereto, the Trustee shall vote the Underlying
Securities in favor of directing, or take such other action as may be
appropriate to direct, the Underlying Securities Trustee to declare the unpaid
principal amount of the Underlying Securities and any accrued and unpaid
interest thereon to be due and payable.

This Certificate is one of the duly authorized Certificates designated as 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

characterization.

Except as provided in the Standard Terms and in paragraph (d) in this Section,
the Trust shall not issue additional Certificates or incur any indebtedness.
The holder of the Class A-2 Certificates shall for so long as such
Certificates are outstanding be the Rights Holders and the transferability of
the Class A-2 Certificates shall be subject to and governed by the provisions
of the Warrant Agent Agreement. In the event that there is more than one
Rights Holder, the Class A-2 Certificates shall be deemed held by each Rights
Holder, with each Rights Holder owning its pro rata share (based on the ratio
of the total number of Call Warrants held by such Rights Holder to the total
number of Call Warrants outstanding) of the Class A-2 Certificates. Section
5.02 of the Standard Terms shall not apply to the Class A-2 Certificates.

     (b) The Class A-1 Certificates have an initial aggregate Certificate
Principal Amount of $29,969,000.00. The Class A-2 Certificates have an initial
Certificate Principal Amount of $31,000.00.

     (c) The holders of the Class A-1 Certificates will be entitled to receive
on each Distribution Date the interest, if any, received on the Underlying
Securities, to the extent necessary to pay interest at a rate of 7.10% per
annum on the outstanding Certificate Principal Amount of the Class A-1
Certificates. The Class A-2 Certificates do not bear interest. On December 1,
2001, the Trustee will pay to the Depositor the amount of interest accrued on
the Underlying Securities from June 1, 2001 to but not including the Closing
Date, to the extent such amount is paid on the Underlying Securities on such
date (and to the extent that the amount of such interest accrued on the
Underlying Securities from the Closing Date to but not including December 1,
2001 has been fully paid).

     (d) The Depositor may sell to the Trustee additional Underlying
Securities on any date hereafter upon at least 3 Business Days notice to the
Trustee and upon (i) satisfaction of the Rating Agency Condition and (ii)
delivery of an Opinion of Counsel to the effect that the sale of such
additional Underlying Securities will not materially increase the likelihood
that the Trust would fail to qualify as a grantor trust under the Code or
cause the Trust to be required to register as an "investment company" as such
term is defined in the Investment Company Act of 1940. 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
or its order, Class A-1 Certificates in a Certificate Principal Amount, that
is an integral multiple of $25.00 and is at least equal to 99.896667% of the
principal amount of such additional Underlying Securities, and without further
action the Certificate Principal Amount of the Class A-2 Certificates shall
increase by the difference between the principal amount of such additional

                                      7
<PAGE>

Underlying Securities and the increase in the Certificate Principal Amount of
the Class A-1 Certificates. Any such additional Certificates authenticated and
delivered or otherwise issued shall have the same terms and rank pari passu
with the corresponding classes of Certificates previously issued in accordance
with this Series Supplement.

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

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

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

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

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

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

               (2) second, to the holders of the Class A-1 Certificates,
          interest accrued and unpaid on such Class; and

               (3) third, to the Depositor for the payment of Trust expenses
          but in an amount not to exceed $9,701 in any calendar year; and

          (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 Certificateholders
          representing 100% of the Voting Rights with respect thereto; and

               (2) second, to the holders of the Class A-1 Certificates until
          the Certificate Principal Amount thereof has been reduced to zero;
          and

               (3) third, to the holders of the Class A-2 Certificates until
          the Certificate Principal Amount thereof has been reduced to zero.

         (b) Notwithstanding any other provision hereof (other than Section
3(c)) if the Underlying Securities are redeemed, prepaid or liquidated in
whole or in part for any reason (including, without limitation, an Event of
Default or a Tax Event) other than at their maturity, the Trustee shall apply
Available Funds on the related Distribution Date (or Special Distribution
Date, if applicable) in the same order of priority as is set forth in Section
5(a). In the event of

                                      8
<PAGE>

any payment on any such date of less than all of the outstanding Class A-1
Certificates, the Class A-1 Certificates to be retired will be selected by the
Trustee or DTC by lot.

     (c) Notwithstanding any other provision hereof, in the event of the
occurrence of (i) a payment default on the Underlying Securities or (ii) an
acceleration of the date of maturity of the Underlying Securities in
connection with a default thereon, the holders of the Certificates
representing a majority of the Voting Rights on the Class A-1 Certificates
will be entitled to direct the Trustee in any such proceeding or direct the
Trustee to sell the Underlying Securities. If the Trustee is directed to sell
the Underlying Securities, the Trustee shall solicit bids for the sale of the
Underlying Securities with settlement thereof on or before the third (3rd)
Business Day after such sale from three leading dealers in the relevant
market. Any of the following dealers (or their successors) shall be deemed to
qualify as leading dealers: (1) Credit Suisse First Boston Corporation, (2)
Goldman, Sachs & Co., (3) Lehman Brothers Inc., (4) Merrill Lynch, Pierce,
Fenner & Smith Incorporated, (5) Bear, Stearns & Co. Inc., and (6) Salomon
Smith Barney 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 such sale or
of an acceleration and a corresponding payment on the Underlying Securities,
the Trustee shall distribute the proceeds to the Certificateholders no later
than two Business Days after the receipt of immediately available funds in
accordance with Section 5(b) hereof.

     (d) In the event that 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 Depositary, or for any Certificates which are not
then held by DTC or any other depository, directly to the registered holders
of the Certificates then outstanding and unpaid. Such notice shall state that,
not later than 30 days after the receipt of such moneys or other property, the
Trustee will 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 the
priorities of distribution established pursuant to Section 5(a) 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 will be deemed to reduce
the principal amount of Certificates on a dollar-for-dollar basis.

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

     (f) If a payment with respect to the Underlying Securities is made to the
Trustee after the payment date of the Underlying Securities on which such
payment was due, then the Trustee will distribute any such amounts received on
the next occurring Business Day (a "Special Distribution Date") as if the
funds had constituted Available Funds on the Distribution Date immediately
preceding such Special Distribution Date; provided, however, that the Record
Date

                                      9
<PAGE>

for such Special Distribution Date shall be five Business Days prior to
the day on which the related payment was received from the Underlying
Securities Trustee.

     (g) In the event that any redemption or early payment premium is received
as a distribution with respect to the Underlying Securities, such amount will
be distributed pro rata to the holders of the Class A-2 Certificates.

     (h) Notwithstanding Section 3.12 of the Standard Terms, if the Underlying
Securities Issuer ceases to file periodic reports as required under the
Exchange Act, the Depositor shall within 5 Business Days instruct the Trustee
to sell the Underlying Securities and distribute the proceeds of such sale to
the Certificateholders in accordance with the order of priority set forth in
Section 5(a) provided, however, the Depositor shall not instruct the Trustee
to distribute or sell the Underlying Securities pursuant to this clause unless
the Underlying Securities Issuer has either (x) stated in writing that it
intends permanently to cease filing reports required under the Exchange Act or
(y) failed to file any required reports for one full calendar year.

     Section 6. Trustee's Fees. (a) As compensation for its services
hereunder, the Trustee shall be entitled to the Trustee Fee as agreed to
separately in a fee agreement among the Depositor and the Trustee. 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 Certificateholders of each of Class A-1 Certificates
then outstanding have voted to require 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. Redemption Upon Exercise of Call Warrants.

     (a) [Reserved].

     (b) On any Call Date, Class A-1 Certificates shall be redeemed at par
plus accrued and unpaid interest on the Class A-1 Certificates upon receipt by
the Trustee of the Call Price on or prior to such Call Date. On any Call Date
on which one or more of the Rights Holders duly exercises less than all of the
Call Warrants then outstanding, the Class A-1 Certificates shall be redeemed
in part and the Class A-1 Certificates to be redeemed will be selected by the
Trustee or DTC by lot and will be paid for on the Call Date.

          (i)     Any Rights Holder, in order for it to exercise its Call
     Rights in whole or in part, shall provide notice to the Trustee (a "Call
     Request") no more than 60 or less than 35 days prior to any Call Date,
     that it is exercising its Call Rights on such Call Date, indicating the
     principal amount of Underlying Securities as to which such call will be
     exercised.

                                      10
<PAGE>

          (ii)    Deliveries of the Underlying Securities purchased on any Call
     Date by a Rights Holder (the "Purchaser") will only be made against
     payment by the Purchaser of the Call Price with respect to such
     Underlying Securities in immediately available funds. Such payment must
     occur no later than 10:00 a.m. New York City time on the Call Date. In
     the event that the Purchaser fails to make such payment by such time (a
     "Purchase Default"), the sale shall be voided and the exercise of Call
     Rights will be deemed not to be effective with respect to such Call Date,
     and the Certificates and the Call Rights shall continue to remain
     outstanding. Subject to receipt of the Call Price as aforesaid on any
     Call Date, the Trustee shall pay the corresponding redemption price set
     forth in clause (b), above, to the Class A-1 Certificateholders on such
     Call Date.

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

          (iv)    The Trustee shall not be obligated to determine whether an
     exercise of Call Rights 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.

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

          (vi)    The Rights Holder shall initially be the Depositor and such
     Call Rights may be transferred to one or more holders. However, the
     Trustee is under no obligation to recognize any notice of transfer unless
     it is signed by the transferor and the transferee.

          (vii)   Any exercise of Call Rights by a Rights Holder must be in a
     minimum principal amount of Underlying Securities equal to $500,000 and
     integral multiples of $500,000 in excess thereof.

          (viii)  The exercise of a Call Warrant shall constitute the
     redemption by the Trust of the Class A-2 Certificates deemed held in
     connection with such Call Warrant by the exercising Rights Holder;
     provided, that no payment shall be made on such Class A-2 Certificate by
     the Trust in connection with such redemption.

          (ix)    Any exercise of Call Rights by a Rights Holder must include
     a certification by the Rights Holder that it is solvent as of the Call
     Date.

     Section 8. Events of Default.

         Within 30 days of the occurrence of an Event of Default actually
known to the Trustee, the Trustee will give notice to the Certificateholders
and the Rating Agency, transmitted by mail, of all such uncured or unwaived
Events of Default known to it. However, except in the case of an Event of
Default relating to the payment of principal of or interest on any of the

                                      11
<PAGE>

Underlying Securities, the Trustee will be protected in withholding such
notice from the Certificateholders 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 Series 2001-2 Certificates.

     (b) The provisions of Section 4.07, Optional Exchange, of the Standard
Terms shall not apply to the Series 2001-2 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 Series 2001-2 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 Certificateholders, pro rata in
proportion to their respective entitlements to interest.

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

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

     (i) Notwithstanding anything in the Trust Agreement to the contrary, the
Trustee may be removed upon 60 days prior written notice delivered by the
holders of Class 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.

                                      12
<PAGE>

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

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

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

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

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

     Section 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 on or an acceleration or other early payment of the
Underlying Securities and the distribution in full of all amounts due to the
Class A-1 and Class A-2 Certificateholders; (ii) the payment in full of the
Class A-1 Certificates upon exercise of all of the issued Call Rights under
Section 7(b); and (iii) 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 Section 5(d) hereof, the Liquidation
Proceeds, if any, shall be deposited into the Certificate Account for
distribution to the Class A-1 and Class A-2 Certificateholders pursuant to
Section 5(a). The Trustee shall only deliver the Underlying Securities to the
purchaser of such Underlying Securities 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

                                      14
<PAGE>

Certificates without the consent of the holders of 100% of such class of
Certificates; provided, however, that no such amendment or modification will
be permitted which would alter the status of the Trust as a grantor trust for
federal income tax purposes. Further, no amendment shall be permitted which
would adversely affect in any material respect the interests of the Class A-1
Certificateholders unless the Rating Agency Condition is satisfied with
respect to such amendment.

     Section 15. Voting of Underlying Securities, Modification of Indenture.
The Trustee, as holder of the Underlying Securities, has the right to vote and
give consents and waivers in respect of the Underlying Securities as permitted
by the Depository and except as otherwise limited by the Trust Agreement. In
the event that the Trustee receives a request from the Depository, the
Underlying Securities Trustee or the Underlying Securities Issuer for its
consent to any amendment, modification or waiver of the Underlying Securities,
the Indenture or any other document thereunder or relating thereto, or
receives any other solicitation for any action with respect to the Underlying
Securities, the Trustee shall mail a notice of such proposed amendment,
modification, waiver or solicitation to each Certificateholder of record as of
such date. The Trustee shall request instructions from the Certificateholders
as to whether or not to consent to or vote to accept such amendment,
modification, waiver or solicitation. The Trustee shall consent or vote, or
refrain from consenting or voting, in the same proportion (based on the
relative outstanding principal balances of the Certificates) as the
Certificates 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, after weighing the votes of the
Certificateholders; provided, however, that, notwithstanding anything in the
Trust Agreement to the contrary, the Trustee shall at no time vote on or
consent to any matter (i) unless such vote or consent would not (based on an
opinion of counsel) alter the status of the Trust as a grantor trust for
federal income tax purposes or result in the imposition of tax upon the
Certificateholders, (ii) which would alter the timing or amount of any payment
on the Underlying Securities, including, without limitation, any demand to
accelerate the Underlying Securities, except in the event of a default under
the Underlying Securities or an event which with the passage of time would
become an event of default under the Underlying Securities and with the
unanimous consent of all outstanding Class A-1 Certificateholders and the
Class A-2 Certificateholders, or (iii) which would result in the exchange or
substitution of any of the outstanding Underlying Securities pursuant to a
plan for the refunding or refinancing of such Underlying Securities except in
the event of a default under the Indenture and only with the consent of
Certificateholders representing 100% of the Voting Rights with respect
thereto. The Trustee shall have no liability for any failure to act resulting
from Certificateholders' late return of, or failure to return, directions
requested by the Trustee from the Certificateholders.

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

                                      15
<PAGE>

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 notation of such consent in made upon this Certificate.
The Trust Agreement also permits the amendment thereof, in certain limited
circumstances, without the consent of the Holders of any of the Certificates.

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

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

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

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

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

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

The Trust and the obligations of the Depositor and the Trustee created by the
Trust Agreement with respect to the Certificates shall terminate upon the
earliest to occur of (i) the payment in full at maturity or sale by the Trust
after a payment default 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
payment in full of the Class A-1

hereof.

Code, an entity whose underlying assets include plan assets by reason of any

account or Keogh plan (any such, a "Plan") may purchase and hold Certificates
if the Plan can represent and warrant that its purchase and holding of the
