         Section 3. Designation of Trust and Certificates. The Trust created
hereby shall be known as the "Corporate Backed Trust Certificates,
Georgia-Pacific Debenture-Backed Series 2001-29 Trust." The Certificates
evidencing certain undivided ownership interests therein shall be known as
"Corporate Backed Trust Certificates, Georgia-Pacific Debenture-Backed Series
2001-29." The Certificates shall consist of the Class A-1 Certificates and the
Class A-2 Certificates (together, the "Certificates").

         (a) The Certificates shall be held through the Depository in book-entry
form and shall be substantially in the forms attached hereto as Exhibit A-1 and
A-2. The Class A-1 Certificates shall be issued in denominations of $25. The
Class A-2 Certificates shall be issued in minimum notional denominations of
$1,000 and integral multiples of $1 in excess thereof. Except as provided in the
Standard Terms and in paragraph (d) of this Section, the Trust shall not issue
additional Certificates or incur any indebtedness.

         (b) The Class A-1 Certificates have an initial aggregate certificate
principal amount (the "Certificate Principal Amount") of $33,900,000. The Class
A-2 Certificates are interest-only Certificates, and have a notional amount
equal to the aggregate principal amount of the Underlying Securities.

         (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
8.50% per annum on the outstanding Certificate Principal Amount of the Class A-1
Certificates. The holders of the Class A-2 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
0.125% per annum on the outstanding notional amount of the Class A-2
Certificates. On October 30, 2001, the Trustee will pay to the Depositor the
amount of interest accrued and paid on the Underlying Securities from April 30,
2001, to but not including the Closing Date. If Available Funds are insufficient
to pay such amount, the Trustee will pay the Depositor its pro rata share, based
on the ratio the amount owed to the Depositor bears to all the amounts owed on
the Certificates in respect of accrued interest, of any proceeds from the
recovery on the Underlying Securities.



                                       7
<PAGE>

         (d) The Depositor may sell to the Trustee additional Underlying
Securities on any date hereafter upon at least 3 Business Days (or such lesser
period as may be agreed by the parties hereto) 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. 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, Class A-1
Certificates and Class A-2 Certificates in the same proportion as the original
Class A-1 Certificates and Class A-2 Certificates bear to the original
Underlying Securities. 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 original Class A-1 Certificates and Class A-2 Certificates,
respectively, issued in accordance with this Series Supplement.

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

         (a) the Underlying Securities set forth on the Underlying Securities
Schedule; 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 Section
3(c), 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:

                           (2) second, to the holders of the Class A-1

such Class pro rata in proportion to their entitlements thereto; and

                           (3) third, any remainder to the Depositor.

                  (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 with respect to
the Underlying Securities in accordance with Section 6(b) below and approved by
100% of the Certificateholders; and

                                       8
<PAGE>

         (b) Notwithstanding any other provision hereof, in the event that the
Underlying Securities are redeemed, prepaid or liquidated in whole or in part
for any reason other than (i) due to the occurrence of an Event of Default, (ii)
the failure of the Underlying Securities Issuer to file periodic reports as
required by the Exchange Act, (iii) a call of the Underlying Securities by the
Underlying Securities Issuer, or (iv) at 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 with respect to the
Underlying Securities 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 outstanding principal amount thereof plus accrued and unpaid
interest thereon;

                  (iii) third, to the holders of the Class A-2 Certificates, 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 8.50% per
annum, assuming no delinquencies, deferrals, redemptions or prepayments on the
Underlying Securities; and

                  (iv) fourth, any remainder to the holders of the Class A-1
Certificates and Class A-2 Certificates pro rata in proportion to the ratio of
the Class A-1 Allocation to the Class A-2 Allocation.

         (c) Notwithstanding any other provision hereof, in the event that the
Underlying Securities are redeemed, prepaid or liquidated in whole or in part
due to the occurrence of an Event of Default or the failure by the Underlying
Securities Issuer to file the periodic reports required under the Exchange Act,
the Trustee shall apply 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.

         (d) Unless otherwise instructed by holders of Certificates representing
a majority of the Voting Rights, thirty (30) days after giving notice pursuant
to Section 8 hereof, the Trustee shall sell the Underlying Securities pursuant
to Section 13 hereof and deposit the Liquidation Proceeds, if any, into the
Certificate Account for distribution not later than two (2) Business Days after
the receipt of immediately available funds in accordance with Section 5 (c)
hereof.

         (e) Notwithstanding any other provision hereof, in the event that the
Underlying Securities are called in whole or in part by the Underlying
Securities Issuer, the holders of the Class A-1 Certificates will share all
amounts received in respect of such call including the redemption premium, if
any, paid by the Underlying Securities Issuer pro rata in the proportion that
the outstanding principal amount of their respective Class A-1 Certificates


                                       9
<PAGE>

bears to the outstanding aggregate principal amount of the Class A-1
Certificates.

         (f) 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 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. Such notice shall state that, not later than 30
days after the receipt of such 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 in accordance with Section 5(c) hereof
(after deducting the costs incurred in connection therewith). 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 Underlying
Securities to Certificateholders will be deemed to reduce the principal amount
and notional principal amount of the Class A-1 Certificates and Class A-2
Certificates, respectively, on a dollar-for-dollar basis.

         (g) 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(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 after the Distribution Date on which such payment was scheduled to
be distributed in respect of the Certificates, 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.

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

         Section 7. Optional Exchange.

         (a) On any Distribution Date, any holder of Class A-1 Certificates and
Class A-2 Certificates may exchange such Certificates for a distribution of
Underlying Securities representing the same percentage of the Underlying
Securities as such Certificates represent of all outstanding Certificates.

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

                  (i) Any Affiliate of the Depositor must provide notice to the
Trustee (an "Exchange Request") no less than 15 days (or such shorter period
acceptable to the Trustee) but not more than 30 days prior to an Optional
Exchange Date that it requests an Optional Exchange of Certificates on such
Optional Exchange Date.

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

                  (iii) The Trustee shall have received an opinion of counsel
stating that the Optional Exchange would not affect the characterization of the
Trust as a "grantor trust" for federal income tax purposes.

                  (iv) 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.

                  (v) Any such Optional Exchange by any Affiliate of the
Depositor, will be subject to the following restrictions: (a) certification to
the Trustee that any Certificates to be exchanged have been held for a minimum


                                       11
<PAGE>

of six months and (b) each Optional Exchange is limited in amount to a maximum
of 5% (except for Certificates acquired by the Underwriter but never distributed
to investors, in which case 25%) of the then outstanding principal amount of the
Certificates.

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

         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. 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 Series 2001-29 Certificates.

         (b) The provisions of Section 4.07, Optional Exchange, of the Standard
Terms shall not apply to the Series 2001-29 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 2001-29 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, proportionately to
the ratio of their respective entitlements to interest.



                                       12
<PAGE>

         (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 the Class A-1 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 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) Notices. 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 or
call 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 Final Scheduled Distribution Date 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; Optional Exchange.. In the
event of a sale of the Underlying Securities pursuant to Section 5(d) hereof,
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) Merrill Lynch,
Pierce, Fenner & Smith Incorporated, (4) UBS Warburg LLC, (5) Salomon Smith
Barney Inc., and (6) 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 to
the Class A-1 Certificateholders and Class A-2 Certificateholders. 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 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 any Class of Certificateholders without confirmation by


                                       15
<PAGE>

each Rating Agency that such amendment will not result in a downgrading or
withdrawal of its rating of such Certificates.

         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 Underlying
Securities 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 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) 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 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 Underlying Securities Indenture and only with the
consent of Certificateholders representing 100% of the Certificates. 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 all of the Certificateholders of such offer
promptly. The Trustee must reject any such offer unless the Trustee is directed
by the affirmative vote of the holders of 100% of all of the Certificates to
accept such offer and the Trustee has received the tax opinion described above.
If pursuant to the preceding sentence, the Trustee accepts any such offer, the
Trustee shall promptly notify the Rating Agencies.



                                       16
<PAGE>

         If an event of default under the Indenture occurs and is continuing,
and if directed by a majority of the outstanding Certificateholders, the Trustee
shall vote the Underlying Securities in an outstanding principal amount equal to
the outstanding certificate principal amount of the Certificates 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.
