         annum on the stated amount of such Certificates and distributable on
         such Certificates on such Distribution Date commencing on May 15, 2004
         and ending on the Final Scheduled Distribution Date;

                  (iii) third, to the Certificateholders, if available, any
         additional payments paid by the Underlying Securities Issuer as a
         result of a delay in the receipt by the Trustee of any interest payment
         on the Underlying Securities;

                  (iv) fourth, pro rata to the Certificateholders, on the Final
         Scheduled Distribution Date only, a distribution of the aggregate
         principal amount of the Underlying Securities;

                  (v) fifth, to the extent there remain Available Funds in the
         Certificate Account, to any creditors of the Trust in satisfaction of
         liabilities thereto; and

                  (vi) sixth, to the extent there remain Available Funds in the
         Certificate Account, to Merrill Lynch Capital Services, Inc. and if no
         Available Funds remain in the Certificate Account then no distribution
         will be made pursuant to this Section 5(a)(vi).

Subject to Section 9(c) hereof, to the extent Available Funds are insufficient
to make any required distributions due to the Certificates on any Distribution
Date, any shortfall will be carried over and will be distributed on the next
Distribution Date on which sufficient funds are available on the Available Funds
to pay such shortfall. Neither Merrill Lynch & Co. nor any of its Affiliates
will have any claim against the Trust pursuant to Section 5(a)(vi) if the Trust
fails to make a distribution on a Distribution Date to such person because no
Available Funds remain in the Certificate Account on such Distribution Date.

                  (b) On an Optional Exchange Date, the Trustee shall distribute
to Merrill Lynch & Co. or any of its Affiliates, other than the Depositor, or
any other Person exercising an optional exchange pursuant to Section 7 hereof,
as the case may be, Underlying Securities in accordance with Section 7 hereof.

                  Section 6. Trustee's Fees; Escrow Agent's Fees. (a) Payment to
the Trustee of Ordinary Expenses shall be as set forth in a separate agreement
between the Trustee and the Depositor. The Trustee agrees that in the event
Ordinary Expenses are not paid in accordance with such agreement, it shall (i)
not have any claim or recourse against the Trust or the property of the Trust
with respect thereto and (ii) continue to perform all of its services as set
forth herein unless it elects to resign as Trustee in accordance with Section
7.08 of the Standard Terms.

                  (b) Extraordinary Trust Expenses shall not be paid out of the
Deposited Assets unless (i) the Trustee is satisfied that it will have adequate
security or indemnity in respect of such costs, expenses and liabilities, and
(ii) all the Certificateholders of Certificates then outstanding have voted to
require the Trustee to incur such Extraordinary Trust Expenses. If Extraordinary
Trust Expenses are not approved unanimously as set forth in clause (ii), such
Extraordinary Trust 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. In addition, if the
conditions in (i) and (ii) are not both satisfied, the Trustee shall not be
obligated to incur any Extraordinary Trust Expense.

                  (c) In the event that one or more Call Holders is required to
deposit the Call Price with the Escrow Agent on the Exercise Date pursuant to
Section 14(c)(iii)(2) hereof, the Depositor and the Escrow Agent shall enter
into an agreement reasonably acceptable to both parties thereto whereby the
Depositor shall pay to the Escrow Agent a fee in consideration for its services
under the Escrow Agreement or Escrow Agreements, as applicable.

                  Section 7. Optional Exchange. (a) Merrill Lynch & Co. or any
of its Affiliates (other than the Depositor), if it holds Certificates, or any
other (i) Person or (ii) group of Affiliated Persons (in each case other than
the Depositor) holding Certificates with an aggregate stated amount of $5
million or more acquired pursuant to the exercise of Call Rights held by it
(provided that, in the case of a group of Affiliated Persons, no single
Affiliated Person holds Certificates with an aggregate stated amount of less
than $500,000 acquired pursuant to the exercise of Call Rights held by it), may
notify the Trustee, not less than 30 days but not more than 60 days prior to any
Optional Exchange Date, that:

                  (i) such Person intends or Affiliated Persons intend to tender
         an Authorized Denomination of Certificates that it holds or they hold
         to the Trustee on such Optional Exchange Date in exchange for a
         proportional amount of Underlying Securities;

                  (ii) such exchange will not cause the Trust or Depositor to
         fail to satisfy the applicable requirements for exemption under Rule
         3a-7 under the Investment Company Act of 1940, as amended;

                  (iii) such exchange will not affect the characterization of
         the Trust as a "grantor trust" under the Code;

                  (iv) in the case of an exchange of less than all outstanding
         Certificates, such exchange will not cause a failure to satisfy the
         minimum requirements for the Certificates to remain listed on the New
         York Stock Exchange, unless the Person or Affiliated



                                       11
<PAGE>

         Persons tendering such Certificates will hold all remaining outstanding
         Certificates upon completion of the exchange of such Certificates
         pursuant to this Section 7;

                  (v) such exchange will not be made with respect to
         Certificates subject to outstanding Call Rights held by any Person or
         Affiliated Persons other than the Person or Affiliated Persons
         exercising such exchange; and

                  (vi) in the case of an exchange by a person other than Merrill
         Lynch & Co. or any of its Affiliates (other than the Depositor), such
         exchange will be made with respect to an aggregate stated amount of
         Certificates equal to the aggregate stated amount of Certificates
         acquired by such Person or Affiliated Persons pursuant to the exercise
         of Call Rights held by it or them.

Upon tender of such Certificates on such Optional Exchange Date, the Trustee
will deliver to the Person or Affiliated Persons tendering such Certificates an
amount of Underlying Securities having a principal amount equal to the aggregate
principal amount of Underlying Securities then held by the Trust times the
aggregate stated amount of Certificates being tendered divided by the aggregate
stated amount of Certificates then outstanding and, in the case of an exchange
by Merrill Lynch & Co. or any of its Affiliates, where such Person or Affiliated
Person holds unexercised Call Rights respecting the exchanged Trust
Certificates, such unexercised Call Rights held by such Person or Affiliated
Person shall be cancelled. Any Call Holder that has properly provided notice of
exercise to the Warrant Agent and has deposited the Call Price with the Escrow
Agent may concurrently designate an Optional Exchange Date, and such Optional
Exchange Date shall be specified in the notice of exercise, provided, however,
that such Optional Exchange Date shall not occur prior to the applicable Call
Date.

                  (b) When a tender offer for the Underlying Securities is
pending, Merrill Lynch & Co. or any of its Affiliates (other than the
Depositor), if it holds Certificates, or any other Person or Affiliated Persons
(other than the Depositor, or an Affiliate of the Person making such tender
offer) holding Certificates with an aggregate stated amount of $5 million or
more acquired pursuant to the exercise of Call Rights held by it (provided that,
in the case of a group of Affiliated Persons, no single Affiliated Person holds
Certificates with an aggregate stated amount of less than $500,000 acquired
pursuant to the exercise of Call Rights, as applicable, held by it), may notify
the Trustee, not less than 5 days but not more than 60 days prior to any such
Optional Exchange Date as they may designate, that:

                  (i) such Person intends or such Affiliated Persons intend to
         tender an Authorized Denomination of certificates with an aggregated
         stated amount of $5 million or more Certificates that it holds or they
         hold to the Trustee on such Optional Exchange Date in exchange for a
         proportional amount of Underlying Securities;

                  (ii) such exchange will not cause the Trust or Depositor to
         fail to satisfy the applicable requirements for exemption under Rule
         3a-7 under the Investment Company Act of 1940, as amended;

                  (iii) such exchange will not affect the characterization of
         the Trust as a "grantor trust" under the Code;

                                       12
<PAGE>

                  (iv) in the case of an exchange of less than all outstanding
         Certificates, such exchange will not cause a failure to satisfy the
         minimum requirements for the Certificates to remain listed on the New
         York Stock Exchange, unless the Person or Affiliated Persons tendering
         such Certificates will hold all remaining outstanding Certificates upon
         completion of the exchange of such Certificates pursuant to this
         Section 7;

                  (v) such exchange will not be made with respect to
         Certificates subject to outstanding Call Rights held by any Person or
         Affiliated Persons other than the Person or Affiliated Persons
         exercising such exchange; and

                  (vi) in the case of an exchange by a person other than Merrill
         Lynch & Co. or any of its Affiliates (other than the Depositor), such
         exchange will be made with respect to an aggregate stated amount of
         Certificates equal to the aggregate stated amount of Certificates
         acquired by such Person or Affiliated Persons pursuant to the exercise
         of Call Rights held by it or them.

Upon tender of such Certificates on such Optional Exchange Date, the Trustee
will deliver to the Person or Affiliated Persons tendering such Certificates an
amount of Underlying Securities having a principal amount equal to the aggregate
principal amount of Underlying Securities then held by the Trust times the
aggregate stated amount of Certificates being tendered divided by the aggregate
stated amount of Certificates then outstanding and, in the case of an exchange
by Merrill Lynch & Co. or any of its Affiliates, where such Person or Affiliate
Person holds unexercised Call Rights respecting the exchanged Trust
Certificates, such unexercised Call Rights held by such Person or Affiliated
Person shall be cancelled.

                  (c) The requirements set forth in paragraphs (a)(ii), (a)(v)
and (a)(vi) of Section 4.07 of the Standard Terms do not apply to an Optional
Exchange pursuant to this Section 7.

                  (d) Any costs associated with the exercise of the rights
granted under paragraphs (a) and (b) of this Section 7 will be borne by the
Person or Affiliated Persons exercising such rights and not by the Trust.

                  Section 8. Events of Default. Within 30 days of its receipt of
notice of the occurrence of an Event of Default, the Trustee will give notice to
the Certificateholders, transmitted by mail, of all such uncured or unwaived
Events of Default actually known to it. However, unless there is 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; provided however, that the Trustee shall
give notice of an Event of Default to the extent required under "Distribution
Election."

                  Section 9. Miscellaneous. (a) The provisions of Section 4.04,
Advances, of the Standard Terms shall not apply to the Certificates.

                  (b) The Certificateholders shall not be entitled to terminate
the Trust or cause the sale or other disposition of the Underlying Securities;
provided, however, that Certificateholders holding all, but not less than all,
of the outstanding Certificates may exercise their rights under Section 13(b)
with respect to all such Certificates.



                                       13

                  (c) 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 payments.

                  (d) The outstanding principal balance of the Certificates
shall not be reduced by the amount of any Realized Loss.

                  (e) 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 Deposited Assets and the issuance of the Certificates and Call
Rights, 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
Call Rights or otherwise incur, assume or guarantee any indebtedness for money
borrowed.

                  (f) The Trust may not consolidate, amalgamate, merge with or
into, or be replaced by or convey, transfer or lease its properties and assets
substantially as an entirety to, any another entity or permit any other entity
to consolidate, amalgamate, merge with or into, or replace the Trust.

                  (g) Except as expressly provided in the Trust Agreement, the
Trust may not sell the Underlying Securities.

                  (h) If the Trustee resigns or is removed as Trustee in
accordance with Section 7.08 of the Trust Agreement, in addition to providing
the Depositor with written notice, the Trustee shall also provide the Rating
Agencies with written notice.

                  (i) Merrill Lynch & Co. shall act as the Market Agent and
shall serve in such capacity in accordance with the terms of the Market Agent
Agreement attached hereto as Exhibit C.

                  (j) Notwithstanding anything in the Trust Agreement to the
contrary, the Trustee may be removed upon 60 days prior written notice delivered
by Certificateholders holding Certificates that represent the Required
Percentage-Removal, and such removal shall take effect upon the appointment of a
successor Trustee and its acceptance of such appointment as provided in the
Trust Agreement.

                  Section 10. Notices. (a) All directions, demands and notices
hereunder or under the Standard Terms shall be in writing and shall be delivered

                  Section 11. Governing Law. This Supplement and the
transactions described herein shall be construed in accordance with and governed
by the laws of the State of New York.

                  Section 12. Counterparts. This 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 13. Termination of the Trust. (a) The Trust shall
terminate upon the earlier of (i) the payment in full at maturity or sale by the
Trust after a payment default on the Underlying Securities and the distribution
in full of all amounts due to the Certificateholders, (ii) the distribution to
the Certificateholders of all Underlying Securities in accordance with the
Distribution Election, (iii) the exchange of all outstanding Certificates for
Underlying Securities pursuant to one or more Optional Exchanges, (iv) the Final
Scheduled Distribution Date and (v) the holders of all, but not less than all,
of the Certificates exercising their election in Section 13(b) below.

                  (b) Certificateholders who hold all, but not less than all, of
the outstanding Certificates may, upon prior written notice to the Rating
Agencies, elect to terminate the Trust at any time; provided that (i) the
exercise of such termination right would not cause the Trust or the Depositor to
fail to satisfy the applicable requirements for exemption under Rule 3a-7 under
the Investment Company Act of 1940, as amended and (ii) if and for so long as
the call warrants remain outstanding, all of the Call Holders have consented to
such termination.

                  (c) To the extent that the provisions of this Section 13
conflict with Section 10.01 of the Standard Terms, the latter shall control.

                  Section 14. Sale or Redemption of Underlying Securities; Call
Right. (a) In the case of Extraordinary Trust Expenses approved by 100% of the
Certificateholders, pursuant to Section 6(b) hereof, the Trustee may, upon prior
written notice to the Rating Agencies, elect to sell all or a portion of the
Underlying Securities to pay such Extraordinary Trust Expenses.

                  (b) As a holder of the Underlying Securities, the Trust may
receive redemption proceeds (the "Redemption Amount") upon the redemption of the
Underlying



                                       16
<PAGE>

Securities, in whole or in part, by the Underlying Securities Issuer pursuant to
the Underlying Securities Indenture and the Underlying Securities Prospectus
Supplement.

                  (i) Upon the redemption of the Underlying Securities in whole,
         but not in part, (A) on the stated maturity date of such Underlying
         Securities or (B) at the option of the Underlying Securities Issuer,
         upon at least 30 days, but not more than 60 days, prior notice pursuant
         to the Underlying Securities Indenture, the Redemption Amount will be
         distributed pro rata to the holders of the Underlying Securities,
         including the Trust. Upon receiving such Redemption Amount, the Trust
         shall distribute the Redemption Amount to the Certificateholders.

                  (ii) Upon any redemption of the Underlying Securities in part
         at the option of the Underlying Securities Issuer upon at least 30
         days, but not more than 60 days, prior notice pursuant to the
         Underlying Securities Indenture, the Redemption Amount will be
         distributed pro rata to the holders of the Underlying Securities,
         including the Trust. Upon any such redemption in part, the Trustee
         shall select by lot (or by such other reasonable procedure as may be
         established by the Trustee) a stated amount of Certificates equal to
         the aggregate amount of Certificates then outstanding multiplied by the
         aggregate principal amount of Underlying Securities subject to
         redemption and then held by the Trust divided by the aggregate
         principal amount of Underlying Securities then held by the Trust;
         provided that the amount of Certificates being selected by lot may be
         reduced by the aggregate stated amount of Certificates called pursuant
         to the exercise of Call Rights prior to such redemption in accordance
         with the terms of the Warrant Agreement. Upon receiving such Redemption
         Amount, the Trust shall distribute the Redemption Amount to the
         Certificateholders plus accrued and unpaid distributions on the
         Certificates to the Redemption Date. Such Redemption Amount will be
         distributed to the Certificateholders entitled to such Redemption
         Amount upon the date such Redemption Amount is received in immediately
         available funds by the Trust if such Redemption Amount is received
         prior to 1:00 pm local time at the office of the Trustee and otherwise
         on the next Business Day. Upon distribution of the Redemption Amount by
         the Trustee, the Trust Certificates called pursuant to the exercise of
         Call Rights and the Trust Certificates selected by lot pursuant to this
         subsection (ii) shall be deemed to have been surrendered for
         cancellation by the Trust, and the aggregate stated amount of the
         outstanding Certificates shall be reduced by the aggregate stated
         amount of such Certificates; provided that the right of a
         Certificateholder to receive the Call Price will not be affected by any
         such deemed surrender. Payment of the Redemption Amount with respect to
         the Certificates will be made to the Call Holder exercising the Call
         Rights.

                  (c) The Call Terms are as follows:

                  (i) The initial holders of the Call Rights are as named in the
         Call Warrants and such holders may transfer the Call Rights, in whole
         or in part, to one or more third parties in privately negotiated
         transactions;

                  (ii) A Call Holder that has met the exercise requirements set
         forth in paragraph (c)(iii) of this Section 14 may, on the Call Date,
         exercise its option to purchase,



                                       17
<PAGE>

         in whole or in part, a principal amount of Certificates proportionate
         to such Call Holder's exercised Call Warrants, in Authorized
         Denominations of Certificates at the Call Price;

                  (iii) In order to exercise its Call Right on a Call Date, a
         Call Holder must, not less than 30 days (or not less than three days in
         the case of an announcement of any redemption of the Underlying
         Securities or other unscheduled payment of the Underlying Securities or
         after receipt of notice of termination of the Trust or not less than
         five Business Days prior to the expiration of a tender offer for the
         Underlying Securities) but not more than 60 days prior to such Call
         Date:

                        (1) notify the Trustee in writing of its intention to
                  exercise such Call Right (which notice is irrevocable, subject
                  to Section 2.02(i)(v) of the Warrant Agreement) and whether
                  such exercise is in connection with a tender offer for the
                  Underlying Securities. In the event that such notice is
                  provided in connection with a tender offer for the Underlying
                  Securities, if the exercising Holder did not receive from the
                  Warrant Agent notice of a Tender Offer, then such Holder shall
                  also provide the Warrant Agent with any information the Holder
                  may have from a third-party source indicating that such Tender
                  Offer is pending.

                        (2) deposit the Call Price with the Escrow Agent (the
                  "Escrow Deposit") to be held in escrow pursuant to an Escrow
                  Agreement reasonably satisfactory to the Trustee and
                  substantially in the form attached hereto as Exhibit D (to be
                  entered into immediately preceding delivery of the Call Price
                  by such Call Holder to the Escrow Agent) until such Call Price
                  is paid by the Trustee to the Certificateholders in accordance
                  with paragraph (d) of this Section 14 or returned to the
                  exercising Holders pursuant to subsection (i) of Section 2.02
                  of the Warrant Agreement; provided, that if all of the
                  outstanding Trust Certificates are to be purchased pursuant to
                  the exercise of the Warrants on an Exercise Date and the
                  exercising Call Holder at such time holds Certificates that
                  are subject to Call Rights, the Call Holder may deposit such
                  Certificates with the Escrow Agent in lieu of the portion of
                  the Call Price that would relate thereto.

                        (3) provide the Trustee with any other documents
                  customary for a transaction of this nature, including a
                  certificate of the Call Holder certifying the solvency of such
                  Call Holder on such date; provided that the Call Holder need
                  not provide any such solvency certificate if the rating of the
                  senior, unsecured long-term debt of the Call Holder, or the
                  Call Holder's credit support provider, if applicable, by
                  Moody's and S&P is in one of the investment grade categories
                  of Moody's and S&P, respectively, on such date.

The provisions of this Section 14(c)(iii)(1) through (3) shall not apply if
Warrants are being exercised upon an acceleration of the Underlying Securities
and payment in full by the Underlying Securities Issuer of all amounts due upon
such acceleration.

                  (d) In connection with any exercise of the Call Rights, the
Trustee shall select by lot (or by such other reasonable procedure as may be
established by the Trustee) a stated amount of the outstanding Certificates to
be surrendered by the Certificateholders thereof to the



                                       18
<PAGE>

Trustee upon any such exercise (other than Trust Certificates held by any Person
to whom a Delivery Certificate was delivered in accordance with Section 2.02(d)
of the Warrant Agreement, as evidenced by the registration of such Delivery
Certificate in the Delivery Register in accordance with Section 4.01 of the
Warrant Agreement), deliver such Certificates to the exercising Call Holder and
the proceeds of the Call Price shall be distributed pro rata among such
Certificateholders on the Call Date in accordance with the provisions of the
Warrant Agreement. Upon distribution of the applicable Call Price, the Trust
Certificates called pursuant to the exercise of Call Rights shall be deemed to
have been surrendered and such Trust Certificates shall be transferred to the
Call Holder; provided that the right of a Certificateholder to receive the Call
Price will not be affected by any such deemed surrender.

                  (e) The rights of the Certificateholders under the Trust
Agreement and the Certificates are limited by the terms, provisions and
conditions of the Trust Agreement and the Warrant Agreement with respect to the
exercise of the Call Rights by the Call Holder. The Certificateholders, by their
acceptance of Certificates, covenant and agree to tender any and all
Certificates to the Warrant Agent upon the Call Holder's exercise of Call Rights
and deposit of the Call Price with the Escrow Agent for such Certificates in
accordance with the applicable procedures in the Warrant Agreement.

                  (f) Upon receipt of a notice of a tender offer for the
Underlying Securities, the Trustee shall deliver notice of the tender offer to
the Warrant Agent and holders of Delivery Certificates (as defined in Section
2.02(d) of the Warrant Agreement) within two Business Days after receipt of
notice from the Tender Offeror (as defined in the Warrant Agreement). Within two
Business Days of the expiration of the period for validly delivering tender
offer exercise notices pursuant to Section 2.02(i)(i) of the Warrant Agreement,
the Trustee shall, after giving effect to the exercise of Call Rights with
respect to Trust Certificates already held by the Call Holder, as set forth in
the Warrant Agreement, (A) select by lot (or by such other reasonable procedure
as may be established by the Trustee) a stated amount of Certificates equal to
the aggregate stated amount of Certificates not subject to Delivery Certificates
then outstanding multiplied by the aggregate principal amount of Call Rights
being exercised divided by the aggregate principal amount of the outstanding
Call Rights and (B) notify the Certificateholders of the selected Certificates
that, subject to Section 2.02(i) of the Warrant Agreement, such Certificates
will be purchased on the Call Date. Upon the Trustee's receipt of the tender
offer proceeds, the Call Price will be distributed pursuant to Section 2.02(e)
and Section 2.02(i)(vi) of the Warrant Agreement pro rata to the
Certificateholders whose Certificates have been purchased and the tender offer
proceeds will be distributed by the Trustee pro rata to the exercising Call
Holders pursuant to Section 2.02(i) of the Warrant Agreement. Upon distribution
of the Call Price and tender offer proceeds, the Trust Certificates called
pursuant to the exercise of Call Rights shall be deemed to have been surrendered
for cancellation by the Trustee and the aggregate stated amount of the
outstanding Trust Certificates shall be reduced by the aggregate stated amount
of such Trust Certificates; provided that the right of a Certificateholder to
receive the Call Price will not be affected by any such deemed surrender.

                  Section 15. Amendments. Notwithstanding anything in the Trust
Agreement to the contrary, in addition to the other restrictions on modification
and amendment contained herein, the Trustee shall not enter into any amendment
or modification of the Trust Agreement that would adversely affect in any
material respect the interests of the Certificateholders or the



                                       19
<PAGE>

Call Holders without the consent of 100% of such Certificateholders or Call
Holders, as the case may be; provided, however, that no such amendment or
modification will be permitted if the Trustee has been advised by the Depositor
that such amendment or modification would alter the status of the Trust as a
"grantor trust" for federal income tax purposes. Further, no amendment shall be
permitted pursuant to paragraphs (vi), (vii) and (x) of Section 11.01(a) of the
Standard Terms without prior written confirmation by each Rating Agency that
such amendment will not result in a downgrading or withdrawal of its rating of
the Certificates. The Trustee may consult with counsel and shall be entitled to
rely upon an Opinion of Counsel for purposes of determining compliance with the
provisions of this Section 15.

                  Section 16. 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, or
(ii) that 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 that with the passage of time would become an event of
default under the Underlying Securities and with the consent of 100% of the
Certificateholders and 100% of the Call Holders, or (iii) except as provided in
the following paragraph, that 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
100% of the Certificateholders and 100% of the Call Holders. The Trustee shall
have no liability for any failure to act resulting from Certificateholders' or
Call Holders' late return of, or failure to return, directions requested by the
Trustee from the Certificateholders and Call Holders.

                  If 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 Certificateholders, the Call Holders
and the Rating Agencies of such offer promptly. Subject to Sections 7(b) and 14
in connection with



                                       20
<PAGE>

a tender offer and the exercise of Call Rights or Optional Exchange rights, the
Trustee must reject any such offer unless the Trustee is directed by the
affirmative vote of 100% of the Certificateholders and 100% of the Call Holders
to accept such offer, the Trustee has received the tax opinion described above
and if the Trustee is so directed, the Trustee shall promptly notify the Rating
Agencies of such direction accompanied by evidence of the affirmative vote of
such Certificateholders and Call Holders.

                  If an event of default under the Underlying Securities
Indenture occurs and is continuing, and if directed by 100% of the
Certificateholders, the Trustee shall vote the Underlying Securities in favor of
directing, or take such other action as may be appropriate to direct, the
Underlying Securities trustee to declare the unpaid principal amount of the
Underlying Securities and any accrued and unpaid interest thereon to be due and
payable.

                  Section 17. Call Right Documentation. Simultaneously with the
execution hereof, the Depositor hereby directs the Trustee, in the name of and
on behalf of the Trust, to enter into a Warrant Agreement and any related
Warrant Certificates (as defined in the Warrant Agreement) evidencing the Call
Rights and to make representations contained therein on behalf of the Trust. At
the direction of the Depositor, the Trustee shall execute such further documents
as may be required to evidence any transfer of any or all of the rights,
interests or obligations under the Warrant Agreement and any related Warrant
Certificates.

                  Section 18. Third Party Beneficiary. The Escrow Agent and each
Call Holder shall be third party beneficiaries of this Trust Agreement.

                  Section 19. Nonpetition Covenant. Solely with respect to the
Trust and the Series and for no other purpose, Section 11.07 of the Standard
terms is hereby deleted and replaced with the following:

                  Section 11.07. Nonpetition Covenant. Notwithstanding any prior
termination of this Trust Agreement, each of the Trustee (including any

agrees that it shall not, until the date which is one year and one day after the
termination of the PPLUS Trust Series SPR-1, acquiesce, petition or otherwise
invoke or cause the Trust to invoke the process of the United States, any State
or other political subdivision thereof or any entity exercising executive,
legislative, judicial, regulatory or administrative functions of or pertaining
to government for the purpose of commencing or sustaining a case by or against
the Trust under a Federal or state bankruptcy, insolvency or similar law or
appointing a receiver, liquidator, assignee, trustee, custodian, sequestrator or
other similar official of such Trust or all or any part of the property or
assets of such Trust or ordering the winding up or liquidation of the affairs of
such Trust.

Trust created hereunder shall not issue or sell any certificates or other
obligations other than the Certificates or otherwise incur, assume or guarantee
any indebtedness for money borrowed.

                  (f) Anything herein to the contrary notwithstanding, none of
the Trustee, the Securities Intermediary or any of the Certificateholders
assumes any of the obligations of the Depositor or any other Person in respect
of the Underlying Securities.

                  (g) The Securities Intermediary expressly agrees with the
Trustee and the Certificateholders that, at all times from and after the date
hereof, any and all of the Deposited Assets held by the Securities Intermediary
in the Certificate Account are to be treated as Financial Assets under, and for
all purposes of, UCC Article 8 and UCC Article 9.

                  Section 2.02. Acceptance by Trustee. With respect to each
Series, the Trustee will acknowledge receipt by it, or by a custodian on its
behalf, of the related Underlying Securities now existing or hereafter acquired,
and declares that it will hold such Underlying Securities and all other

hold all such assets and such other assets (including Underlying Securities
acquired from a Person other than the Depositor) comprising the Trust for a
given Series, in trust for the exclusive use and benefit of all present and
future Certificateholders of such Series and for the purposes and subject to the
terms and conditions set forth in this Trust Agreement.

                  Section 2.03. Representations and Warranties of the Depositor.
The Depositor hereby represents and warrants to the Trustee that as of the
Closing Date or as of such other date specifically provided herein or in the

         existing and in good standing under the laws of the State of Delaware;




<PAGE>


                                       24

                  (ii) with respect to each Supplement, to the Depositor's
         knowledge but without having made any independent inquiry, the
         information set forth in the Underlying Securities Schedule with
         respect to each Underlying Security is true and correct in all material
         respects at the date or dates, respecting which, such information is
         furnished;

                  (iii) the execution and delivery of this Trust Agreement by
         the Depositor and its performance of and compliance with the terms of
         this Trust Agreement will not violate the Depositor's certificate of
         incorporation or by-laws or constitute a default (or an event which,
         with notice or lapse of time, or both, would constitute a default)
         under, or result in the breach or acceleration of, any material
         contract, agreement or other instrument to which the Depositor is a
         party or which may be applicable to the Depositor or any of its assets;

                  (iv) the Depositor has the full power and authority to enter
         into and consummate all transactions contemplated by this Trust
         Agreement, has duly authorized the execution, delivery and performance
         of this Trust Agreement and has duly executed and delivered this Trust
         Agreement. This Trust Agreement, upon its execution and delivery by the
         Depositor and assuming due authorization, execution and delivery by the
         Trustee, will constitute a valid, legal and binding obligation of the
         Depositor, enforceable against it in accordance with the terms hereof,
         except as such enforcement may be limited by bankruptcy, insolvency,
         reorganization, receivership, moratorium or other laws relating to or
         affecting the rights of creditors generally, and by general equity
         principles (regardless of whether such enforcement is considered a
         Proceeding in equity or at law); and

                  (v) any additional representations and warranties, if any,
         that may be specified in the applicable Supplement.

                  It is understood and agreed that the representations and
warranties of the Depositor set forth in this Section 2.03 shall survive
delivery of the respective documents and the Underlying Securities to the
Trustee and shall inure to the benefit of the Trustee on behalf of the
Certificateholders notwithstanding any restrictive or qualified endorsement or
assignment. Upon discovery by any of the Depositor or the Trustee of a breach of
any of the foregoing representations and warranties which materially and
adversely affects the interests of the Certificateholders, the party discovering
such breach shall give prompt written notice thereof to the other party.

                  Section 2.04. Breach of Representation, Warranty or Covenant.
Within 90 days of the earlier of discovery by the Depositor or receipt of notice
by the Depositor of a breach of any representation or warranty of the Depositor
set forth in Section 2.03 that

                                       25

materially and adversely affects the interests of the Certificateholders of a
given Series, the Depositor shall cure such breach in all material respects.

                  Section 2.05. Agreement to Execute, Authenticate and Deliver
Certificates. With respect to each Series and the related Trust, the Trustee
hereby agrees and acknowledges that it will, concurrently with the Grant to and
receipt by it of the related Underlying Securities, cause to be executed,
authenticated and delivered to or upon the written order of the Depositor, in
exchange for the Underlying Securities and such other assets constituting the
Trust for a given Series, Certificates duly authenticated by or on behalf of the
Trustee in an Authorized Denomination evidencing ownership of the entire Trust
for such Series, all in accordance with the terms and subject to the conditions
of Section 5.02.

                  Section 2.06. Custody and Holding of Deposited Assets. (a)
With respect to each Series, the Trustee shall hold and maintain the Deposited
Assets with the Securities Intermediary in and through, and hereby directs the
Securities Intermediary to credit any and all such Deposited Assets to, the
Certificate Account (all as further provided in this Article II) in such manner
as shall enable the Trustee to be and have the rights of an Entitlement Holder
with respect to, and have sole dominion and control (including, without
limitation, Securities Control) over, such Deposited Assets.

                  (b) The Securities Intermediary hereby represents, warrants,
covenants and agrees that from and after the Closing Date:

                  (i) Each Certificate Account is a Securities Account, with the
         Trustee (for its benefit and the benefit of the Certificateholders) as
         the Entitlement Holder in, and having sole dominion and control
         (including, without limitation, Securities Control) over, any and all
         Deposited Assets (including, without limitation, any and all assets and
         properties referred to in clause (ii) below) in such Certificate
         Account.

                  (ii) All assets and properties from time to time transferred
         or credited to the Certificate Account constitute Financial Assets.

                  (iii) The Securities Intermediary is (and will remain) a
         securities intermediary and is acting (and will continue to act) as
         such with respect to the Certificate Account, the Deposited Assets
         therein and the Trustee as Entitlement Holder. Unless otherwise
         instructed by the Trustee in writing, the Securities Intermediary will
         treat the Trustee (for its benefit and the benefit of the
         Certificateholders) as entitled to exercise the rights that comprise
         the Deposited Assets in each Certificate Account. Further, the

         service for customers and maintains Securities Accounts in the name of
         such customers reflecting ownership of or interest in such Securities,
         (B) will maintain its books and records reflecting such Book-Entry
         Securities in the State of New York and (C) if the Trustee maintains
         one or more Certificate Accounts with the Securities Intermediary, will
         have entered into, and will maintain in full force and effect, an
         agreement with the Trustee (which, on the date hereof, is comprised of
         this Trust Agreement) to the effect that their respective rights and
         obligations in respect of each other, said Underlying Securities and
         said Certificate Accounts are governed by the laws of the State of New
         York.

                  (iv) The Securities Intermediary shall hold any and all assets
         and properties from time to time comprising the Deposited Assets
         (whether individually or as part of a fungible bulk) in a manner such
         that the Trustee will have dominion and control (including, without
         limitation, Securities Control) over such Deposited Assets. The
         Securities Intermediary will credit to the appropriate Certificate
         Account (and will thereby or by book entry or otherwise identify as
         being subject to the Grant to the Trustee hereunder) any and all assets
         and properties from time to time comprising the Deposited Assets in
         accordance with Section 2.06(a) hereof.

                  (v) To effect the intention of clauses (i) through (iv) above,
         the Securities Intermediary or its agent maintains (and will continue
         to maintain)

                           (A) one or more Securities Accounts with the
                  Depository. The Securities Intermediary or its agent will
                  instruct the Depository to credit such Securities Accounts of
                  the Securities Intermediary or its agent with the Depository
                  with the Depository Securities comprising from time to time
                  the Deposited Assets; and

                           (B) one or more Fed Member Securities Accounts to
                  which the Securities Intermediary through its agent will
                  instruct the Fed to credit, in accordance with the Book-Entry
                  Regulations, all Book-Entry Securities from time to time
                  comprising the Deposited Assets.


                                   ARTICLE III

applicable Supplement, the respective Underlying Securities and any applicable
Credit Support Instruments. With respect to each Trust, and subject only to the
above-described standards and the terms of these Standard Terms, the related
Supplement and the respective Underlying Securities and applicable Credit
Support Instruments, if any, the Trustee shall have full power and authority,
acting alone or through Administrative Agents as provided in Section 7.02, to do
or cause to be done any and all things in connection with such administration
which it deems necessary to comply with the terms of these Standard Terms and
the applicable Supplement.

                  (b) The duties of the Trustee shall be performed in accordance
with applicable local, State and Federal law, and the Trustee shall, at the
direction of the Depositor, make any and all filings, reports, notices or
applications with (as prepared by the Depositor), and seek any comments and
authorizations from, the Commission and any State securities authority on behalf
of the Trust for each Series.

                  Section 3.02. Collection of Certain Underlying Security

                  Section 3.03. Certificate Accounts. (a) For each Series, the

benefit of Certificateholders of such Series. The Trustee on behalf of such
Certificateholders shall possess all right, title and interest in all funds on
deposit from time to time in each Certificate Account and in all proceeds
thereof. With respect to each Series and in accordance with Section 2.06, the

without limitation, Securities Control) of the Trustee for the benefit of the
related Certificateholders. With respect to each Series, not later than the
close of business on the Business Day on which the Trustee receives such amounts
in the form of immediately available funds (so long as such funds are received

                  (iv) any payments in respect of any such Credit Support;

                  (v) any Advances made as required pursuant to Section 4.04;
         and

                  (vi) any interest or investment income earned on funds
         deposited in the related Accounts.

                  Unless otherwise specified in the applicable Supplement, it is
understood and agreed that payments in the nature of prepayment or redemption
penalties, late payment charges, default interest or reinvestment income which
may be received by the Trustee shall be deposited by the Trustee in the
Certificate Account and shall not be retained by the Trustee for its own
account.

                  If, at any time, the Certificate Account for any Series ceases
to be an Eligible Account, the Trustee shall within five Business Days (or such
longer period, not to exceed 30 calendar days, as to which the Rating Agency
Condition is met) establish a new Certificate Account meeting the conditions
specified above and the Trustee shall within five Business Days transfer any
cash and any investments on deposit in the Certificate Account to such new
Certificate Account, and from the date such new Certificate Account is
established, it shall be the Certificate Account for such Series.

                  (b) The Trustee shall give notice to the Depositor of the
location of each Eligible Account constituting the Certificate Account and prior
to any change thereof, if such Eligible Account is or will be located at an
institution other than United States Trust Company of New York.

                  Section 3.04. Distribution or Sale of the Underlying
Securities. If (a) there occurs a payment default on the Underlying Securities,
(b) there occurs an acceleration of the date of maturity of the Underlying
Securities, or (c) the Underlying Securities Issuer of any Concentrated
Underlying Securities ceases to be a reporting company under the Exchange Act,
then the Trustee, upon receiving notice of the events set forth in (a), (b) or
(c) shall exercise one of the following remedies, in accordance with the
Distribution Election:

                  (i) immediately direct the Market Agent to sell the Underlying
         Securities and a pro rata portion of the Related Assets held by such
         Trust, in accordance with the Sale Procedures, and the Liquidation
         Proceeds, if any, shall be deposited into the Certificate Account for
         distribution in accordance with the Allocation Ratio on the first
         Business Day following such deposit into the Certificate Account;




<PAGE>


                                       29

                  (ii) distribute the Underlying Securities and a pro rata
         portion of the Related Assets in accordance with the Allocation Ratio
         to each Holder's last address as it appears in the Certificate Register
         within three Business Days of receiving the notice referred to in the
         first sentence of this Section 3.04; or

                  (iii) provide that the Holders of a given Series or Class may
         vote in favor of either (i) or (ii), in accordance with the procedures
         set forth in the applicable Supplement.

In the case of a sale by the Market Agent of Underlying Securities and Related
Assets pursuant to clause (i) of this Section 3.04, the Trustee shall deliver
such Underlying Securities and Related Assets to the purchaser of such
Underlying Securities and Related Assets only against payment in same day funds
and the Trustee shall deposit the same into the Certificate Account.

                  Section 3.05. Investment of Funds in the Accounts. The Trustee
may direct any depository institution maintaining the Certificate Account or the
Reserve Account, if any, for the Series and any other segregated Eligible
Account, which Eligible Account shall be a Securities Account the contents of
which are held for the benefit of Certificateholders of such applicable Series
(each, an "Account"), to invest the funds therein at the specific written
direction of the Depositor in one or more Eligible Investments bearing interest
or sold at a discount, which shall be held to maturity unless payable on demand
and which funds shall not be reinvested upon the maturity or demand for payment
of such Eligible Investment. If the Depositor does not provide any investment
directions by 10:00 a.m. on any Business Day, funds held in any Account will be
invested in the Eligible Investments specified in clause (iv) of the definition
thereof until receipt of investment directions to the contrary. Investments of
such funds shall be invested in Eligible Investments that will mature so that
such funds will be available for distribution on the next Distribution Date.
Except as otherwise provided in the applicable Supplement, any earnings with
respect to such Eligible Investments shall be paid to, and any losses with
respect to such Eligible Investments shall be solely for the account of, the
Certificateholders in proportion to their interest in the invested funds. In the
event amounts on deposit in an Account are at any time invested in an Eligible
Investment payable on demand, the Securities Intermediary, on behalf of the
Trustee and the Trust, shall:

                  (i) consistent with any notice required to be given
         thereunder, demand that payment thereon be made on the last day such
         Eligible Investment may otherwise mature hereunder in an amount equal
         to the lesser of (1) all amounts then payable thereunder and (2) the
         amount required to be withdrawn on such date; and




<PAGE>


                                       30

                  (ii) demand same day payment of all amounts due thereunder
         upon a determination by the Trustee that such Eligible Investment would
         not constitute an Eligible Investment in respect of funds thereafter on
         deposit in any Account.

None of the Trustee, the Depositor or the Securities Intermediary shall in any
way be held liable by reason of any insufficiency in any Account resulting from
any loss on any Eligible Investment made in accordance with this Trust
Agreement.

                  Section 3.06. Maintenance of Credit Support. (a) On the
applicable Closing Date, the Trustee at the written direction of the Depositor
or, if so specified in the applicable Supplement, the Depositor shall, to the
extent specified in the applicable Supplement, establish and maintain, or enter
into, as applicable, in the name of the Trustee, either as part of the related
Trust or outside it, for the benefit of the Certificateholders of the related
Series, the Credit Support specified in the applicable Supplement. To the extent
specified in the applicable Supplement, the Depositor will make or cause to be
made any initial deposit to the Certificate Account or any Reserve Account
(which shall be an Eligible Account) for the related Series as of the Closing
Date. Unless the Supplement for a given Series provides otherwise, if a Reserve
Account exists for such Series, collections with respect to the Underlying
Securities for such Series not distributed to the Certificateholders of such
Series shall be deposited in the Reserve Account. The Reserve Account, if any,
shall be an asset of the Depositor (and the income earned on any amounts held in
the Reserve Account shall be allocable to the Depositor, who agrees to include
any such income in its gross income for all federal, state and local income and
franchise tax purposes) and will not be a part of or otherwise be included in
the Trust but will be held for the benefit of the Certificateholders.

                  (b) Amounts on deposit in the Reserve Account and amounts
available pursuant to any other Credit Support for such Series shall be applied
by the Trustee to make distributions of principal of and premium (if any) and
interest on the Certificates of such Series as required pursuant to Section 4.01
and the applicable Supplement to the extent that funds are not otherwise
available for such purpose. If specified in such Supplement, immediately after
each Distribution Date, amounts on deposit in the Reserve Account for such
Series in excess of a specified amount shall be paid to the Person so specified
in such Supplement.

                  Section 3.07. Realization upon Defaulted Underlying
Securities. (a) The Trustee on behalf of the Certificateholders, shall assert
claims under each applicable Credit Support Instrument, and shall take such
reasonable steps as are necessary to receive payment or to permit recovery
thereunder with respect to any defaulted Underlying Securities, subject in all
cases to the provisions of Article VII hereof.

                  (b) Unless otherwise provided in the related Supplement, if
the Trustee is unable to obtain full recovery in respect of a defaulted
Underlying Security and any related



<PAGE>


                                       31

Credit Support Instrument pursuant to Section 3.07(a), the Trustee shall follow
or cause to be followed such normal practices and procedures as it deems
necessary or advisable to realize upon such defaulted Underlying Security and
such Credit Support Instrument, subject in all cases to the provisions of
Article VII hereof.

                  (c) If the Liquidation Proceeds of a defaulted Underlying
Security are less than the sum of (i) the outstanding principal balance of the
defaulted Underlying Security and (ii) the aggregate amount of expenses incurred
by the Trustee in connection with the practices and procedures referred to in
paragraph (b) of this Section 3.07 to the extent reimbursable under these
Standard Terms and the related Supplement, the Trust for the applicable Series
shall recognize a Realized Loss equal to the amount of such difference. Any such
Realized Loss shall be allocated in accordance with Section 4.05.

                  Section 3.08. Retained Interest. The Retained Interest, if
any, in any Underlying Security shall initially be held by the Person so
specified in the related Supplement as and to the extent specified therein.

                  Section 3.09. Access to Certain Documentation. The Trustee
shall provide to any Federal, State or local regulatory authority that may
exercise authority over any Certificateholder access to the documentation in the
Trustee's possession regarding the Underlying Securities required by applicable
laws and regulations. Such access shall be afforded without charge, but only
upon reasonable written request and during normal business hours at the offices
of the Trustee designated by it. In addition, access to the documentation in the
Trustee's possession regarding the Underlying Securities related to a given
Series (or Class within such Series) will be provided to any Certificateholder
of such Series (or Class) upon reasonable written request during normal business
hours at the offices of the Trustee designated by it at the expense of the
Certificateholder requesting such access.

                  Section 3.10. Reports by the Depositor. The Depositor shall:

                  (i) file with the Trustee, within 30 days after the Depositor
         is required to file the same with the Commission, copies of the annual
         reports and of the information, documents and other reports (or copies

         with the rules and regulations prescribed by the Commission, such
         additional information, documents and reports with respect to

         Section 313(c)), such summaries of any information, documents and

         Agreement. For purposes of this clause (iv), such compliance shall be
         determined without regard to any period of grace or requirement of
         notice provided under this Trust Agreement.

Any reports, statements, documents or other information required to be furnished
by the Depositor to the Trustee pursuant to these Standard Terms or any
Supplement shall be deemed to have been delivered to the Trustee if the Trustee
is in possession of such reports, statements, documents or other information at
the time they are to be furnished pursuant to these Standard Terms or any
Supplement.

                  Section 3.11. Charges and Expenses. Except as otherwise
provided in these Standard Terms or the related Supplement, no amounts in the
nature of fees or charges shall be payable by or withheld from the Trust, the
Depositor or any other person and there shall be no recourse or claim against
the Trust or the property of the Trust for all or any part of any fees or
charges payable to any person.


                                   ARTICLE IV

                 DISTRIBUTIONS AND REPORTS TO CERTIFICATEHOLDERS

                  Section 4.01. Distributions. (a) On each Distribution Date for
a given Series, the Trustee shall apply Available Funds in the Certificate
Account for such Series in the manner and priority set forth in the Supplement
for such Series. In any event, however, any amounts collected during any period
shall be distributed to the Holders no later than the Distribution Date
immediately following the receipt thereof.



<PAGE>


                                       33


                  (b) All distributions to Holders shall be payable only from
Available Funds, and no provision of this Trust Agreement shall be deemed to
create any obligation on the part of the Trustee or the Depositor to make any
distribution from any other source.

                  Section 4.02. Distributions on Certificates. (a) Distributions
on any Certificate that are payable and are punctually paid or duly provided for
on any Distribution Date shall be distributed to the Person in whose name such
Certificate (or one or more Predecessor Certificates) is registered at the close
of business on the related Record Date notwithstanding the cancellation of such
Certificate upon any transfer or exchange subsequent to such related Record
Date.

                  The distribution of interest and principal on Certificates
shall be made:

                  (i) if the Certificateholder is a Depository, to the
         Depository, which shall credit the relevant Participant's account at
         such Depository in accordance with the policies and procedure of the
         Depository; or

                  (ii) if the Holder is not a Depository, at the Corporate Trust
         Office (except as otherwise specified pursuant to the applicable
         Supplement) or, at the option of the Trustee, by check mailed to the
         address of the Person entitled thereto as such address shall appear in
         the Certificate Register or, if provided pursuant to the applicable
         Supplement and in accordance with arrangements satisfactory to the
         Trustee, at the option of the registered Holder by wire transfer to an
         account designated by the registered Holder. Notwithstanding clause (i)
         of this paragraph (a), with respect to a Holder of Certificates not
         held in a Depository and having at least the Minimum Wire Denomination,
         such payment shall be made by wire transfer of immediately available
         funds to the account designated by such Holder in a written request
         received by the Trustee not later than 10 days prior to such
         Distribution Date; provided, however, that if a wire transfer cannot be
         made for any reason, payment shall be made by check. The Trustee shall
         not be required to send federal funds wires until any corresponding
         payments which were not same day funds when received by it have become
         same day funds.

                  (b) Each Certificate delivered under this Trust Agreement upon
transfer of or in exchange for or in lieu of any other Certificate shall carry
the rights to interest accrued and undistributed, and to accrue, that were
carried by such other Certificate.

                  (c) All computations of interest due with respect to any
Certificate of any Series or Class within such Series shall be made as specified
in the Supplement applicable to that particular Series or Class.




<PAGE>


                                       34

                  (d) With respect to any computations or calculations to be
made under these Standard Terms, the applicable Supplement and the Certificates,
except as otherwise provided, all percentages resulting from any calculation of
accrued interest will be rounded, if necessary, to the nearest 1/100,000 of 1%
(.0000001), with five one-millionths of a percentage point rounded upward.

                  (e) The final distribution of principal and/or premium shall
be made upon presentation and surrender of such Certificates at the Corporate
Trust Office.

                  Section 4.03. Reports to Certificateholders. On the fifth
Business Day following each such Distribution Date the Trustee shall forward or
cause to be forwarded to the Depositor, each Holder of such Series, to each
Rating Agency rating such Series and such other Persons as may be specified in
such Supplement, a statement setting forth:

                  (i) the amounts received by the Trustee as of the last such
         statement in respect of principal, interest and premium on the
         Underlying Securities, the Swap Receipt Amount, if any, and any other
         derivatives transaction that may be entered into by the Trust pursuant
         to the terms of these Standard Terms and the related Supplement;

                  (ii) the Swap Distribution Amount, if any, received by the
         Trustee as of such Distribution Date and any other amounts payable
         pursuant to any other derivatives transaction that may be entered into
         by the Trust pursuant to the terms of these Standard Terms and the
         related Supplement;

                  (iii) the amount of compensation received by the Trustee, and
         any Administrative Agent, for the period relating to such Distribution
         Date, and such other customary and sufficient information as is
         reasonably necessary to enable Holders to calculate their federal
         income tax liability with respect to the Certificates; provided,
         however, the Trustee shall be permitted to seek the advice of counsel
         and such other experts as it may deem necessary in its reasonable
         judgment in order to determine that information which is reasonably
         necessary to provide to the Holders;

                  (iv) the amount of the distribution on such Distribution Date
         to Holders allocable to principal of and premium, if any, and interest
         on the Certificates of each such Class and to the Retained Interest,
         and the amount of aggregate unpaid interest accrued as of such
         Distribution Date;

                  (v) in the case of each Class of Floating Rate Certificates of
         such Series, the respective Floating Pass-Through Rate applicable to
         each such Class on such Distribution Date, as calculated in accordance
         with the method specified in such Certificates and the related
         Supplement;



<PAGE>


                                       35


                  (vi) if the Supplement provides for Advances, the aggregate
         amount of Advances, if any, included in such distribution, and the
         aggregate amount of unreimbursed Advances, if any, at the close of
         business on such Distribution Date;

                  (vii) the aggregate stated principal amount and, if
         applicable, notional amount of the Underlying Securities related to
         such Series, the current interest rate or rates thereon at the close of
         business on such Distribution Date, and the current rating assigned to
         the Certificates, as provided to the Trustee in writing in an
         instrument specifically referring to this Trust Agreement by the
         applicable rating agency;

                  (viii) the aggregate Certificate Principal Balance (or
         Notional Amount, if applicable) of each Class of such Series at the
         close of business on such Distribution Date, separately identifying any
         reduction in such aggregate Certificate Principal Balance (or Notional
         Amount) due to the allocation of any Realized Losses on such
         Distribution Date or otherwise as may be specified by the Depositor;

                  (ix) as to any Series (or any Class within such Series) for
         which Credit Support has been obtained, the amount or notional amount
         of coverage of each element of Credit Support (and rating, if any,
         thereof) included therein as of the close of business on such
         Distribution Date; and

                  (x) any other information appropriate for a Series, as
         specified in the applicable Supplement.

Within a reasonable period of time after the end of each calendar year, the
Trustee shall furnish to each Person who at any time during each such calendar
year was a Holder a statement containing the information set forth in clause
(iii) above, aggregated for such calendar year during which such person was a
Holder. Such obligation of the Trustee shall be deemed to have been satisfied to
the extent that substantially comparable information shall be provided by the
Trustee pursuant to any requirements of the Code as are from time to time in
effect. The Trustee shall supply to Holders in writing at such Holder's expense
who so request all materials received by the Trustee from the Underlying
Securities Issuer.

                  Section 4.04. Advances. (a) Unless otherwise specified in the
applicable Supplement, the Trustee shall have no obligation to make Advances (as
defined below) with respect to the Underlying Securities or in favor of the
Holders of any Series (or Class within such Series) of Certificates.

                  (b) However, as and to the extent provided in the Supplement
for a given Series, and subject to the terms of paragraphs (c) and (d) of this
Section 4.04, on or prior to each Distribution Date, the Trustee shall advance
or cause to be advanced in immediately available funds for deposit in the
Certificate Account for such Series an advance (each, an



<PAGE>


                                       36

"Advance") in an amount equal, unless otherwise specified in the related
Supplement, to the aggregate of distributions of principal, premium (if any) and
interest due on the Underlying Securities for such Series (or Class) during the
related Collection Period, to the extent remaining unpaid at the time of such
Advance. In satisfaction of its obligation to make such Advances, the Trustee
shall make such Advances from its own funds and may recover Advances from late
collections received by the Trustee on the applicable Underlying Securities,
proceeds from any applicable Credit Support, if any, and Liquidation Proceeds
with respect to the Underlying Securities for such Series or Class, as specified
in the related Supplement, as to which any such Advance was made.

                  (c) Notwithstanding any provision herein to the contrary, no
Advance shall be required to be made hereunder if the Trustee reasonably
believes that it will be unable to recover such Advance from related late
collections, Credit Support proceeds, if any, or Liquidation Proceeds with
respect to the applicable Underlying Securities. It is further understood and
agreed that the Trustee shall not be obligated to make any Advances in respect
of reductions in the amount of collections on the Underlying Securities due to
bankruptcy proceedings with respect to the Underlying Securities or the obligors
thereof.

                  (d) Notwithstanding any provision herein to the contrary,
unless otherwise provided in the related Supplement for a given Series, any
Advances made in respect of any Underlying Securities related to such Series (or
Class within such Series) that subsequently are deemed by the Trustee to be
nonrecoverable from related late collections, Credit Support proceeds, if any,
or Liquidation Proceeds may be reimbursed to the Trustee through the application
of amounts on deposit in the Certificate Account for such Series allocable to
any of such Underlying Securities prior to the distributions of interest,
premium (if any) and principal with respect to the Certificates of such Series
or Class.

                  Section 4.05. Allocation of Realized Losses and Trust
Expenses. With respect to any Series, Realized Losses and Extraordinary Trust
Expenses, if any, shall be allocated on any Distribution Date in accordance with
the Allocation Ratio, provided, however, that distributions pursuant to Section
3.04 shall be completed as the earliest practicable date.

                  Section 4.06. Compliance with Withholding Requirements. (a)
Notwithstanding any other provision of this Trust Agreement to the contrary, the
Trustee shall comply with all Federal withholding requirements respecting
distributions to Holders of interest or original issue discount that the Trustee
believes are applicable under the Code. The consent of Holders shall not be
required for such withholding.

                  (b) Each Holder will provide the Trustee (and, so long as the
Certificates are held at a Depository in the form of Global Certificates, each
Beneficial Owner of the Certificates will provide such Depository and the
Trustee) with evidence that there should not



<PAGE>


                                       37

be any withholding tax assessed for Federal income tax purposes in respect of
distributions to such Holder, such evidence to take the form of a statement, on
a duly executed and up-to-date Internal Revenue Service Form W-8 (or successor
form), Form W-9 (or successor form), or Form 4224 (or successor form), as
applicable, that identifies the Beneficial Owner of the Certificate; provided,
however, that for so long as the Certificates are held at a Depository in the
form of Global Certificates, the Holder shall have no obligation to provide the
Trustee with any such evidence except to the extent it has received such
evidence from Beneficial Owners of the Certificates. The Trustee shall not be
required to accept any such Internal Revenue Service forms if it believes that
they are not accurate (but the Trustee shall not be required to make any
independent investigation to determine their accuracy).

                  (c) If any tax or other governmental charge shall become
payable by or on behalf of the Trustee, including any tax or governmental charge
required to be withheld from any payment by the Trustee under the provisions of
any applicable law or regulation with respect to any Underlying Securities or
the Certificates, such tax or governmental charge shall be payable by the Holder
and may be withheld by the Trustee. The consent of the Holder shall not be
required for such withholding. In the event the Trustee does withhold any amount
from interest or original issue discount distributions or Advances thereof to
any Holder pursuant to Federal withholding requirements, the Trustee shall
indicate in the statement required pursuant to Section 4.03 the amount so
withheld.

                  (d) The Depositor and the Trustee shall have the right to
refuse the surrender, registration of transfer or exchange of any Certificate
with respect to which such tax or other governmental charge shall be payable
until such payment shall have been made by the Holder thereof.

                  Section 4.07. Optional Exchange. (a) The terms and conditions,
if any, of an Optional Exchange will be specified in the related Supplement;
provided, however, that any right of Optional Exchange shall be exercisable only
to the extent that the Depositor provides upon the Trustee's request an Opinion
of Counsel that (i) such exchange would not be inconsistent with continued
satisfaction of the applicable requirements for exemption under Rule 3a-7 (or
other applicable rule or exemption) under the Investment Company Act of 1940, as
amended, and all applicable rules, regulations and interpretations thereunder
and (ii) such exchange would not affect the characterization of the Trust as a
"grantor trust" under the Code. The terms of an Optional Exchange may include,
but are not limited to, the following:

                  (i) a requirement that the exchanging Holder tender to the
         Trustee Certificates of each Class within such Series;




<PAGE>


                                       38

                  (ii) a minimum Certificate Principal Balance or Notional
         Amount, as applicable, with respect to Certificates being tendered for
         exchange by a single Holder;

                  (iii) a requirement that the Certificate Principal Balance or
         Notional Amount, as applicable, of each Certificate tendered for
         exchange be an Authorized Denomination;

                  (iv) specified dates on which a Holder may effect such an
         Optional Exchange (each, an "Optional Exchange Date"), as specified in
         the applicable Supplement;

                  (v) limitations on the right of an exchanging Holder to
         receive any benefit upon Optional Exchange from any Credit Support; and

                  (vi) adjustments to the value of the proceeds of any Optional
         Exchange based upon required prepayment of future expense allocations
         and the establishment of a reserve for any unanticipated Extraordinary
         Trust Expenses.

                  (b) Unless otherwise provided in the applicable Supplement, no
Certificate may be exchanged pursuant to this Section 4.07 unless the Trustee
has received at least 30 days (or such shorter period acceptable to the Trustee
or specified in the applicable Supplement) but not more than 45 days prior to an
Optional Exchange Date a telegram, telex, facsimile transmission or letter from
a member of a national securities exchange or the National Association of
Securities Dealers, Inc., the Depository (in accordance with its normal
procedures) or a commercial bank or trust company in the United States setting
forth the name of the Holder, the Certificate Principal Balance or Notional
Amount of such Registered Certificate to be exchanged and the number or a
description of the tenor and the terms of such Certificate, a statement that the
Optional Exchange is being exercised thereby and an assurance that the
Registered Certificate to be exchanged with the form entitled "Option to Elect
Exchange" on the reverse of the Registered Certificate duly completed will be
received by such Trustee not later than five Business Days after the date of
such telegram, telex, facsimile transmission or letter, and such Certificate and
form duly completed must be received by such Trustee by such fifth Business Day.
Any tender by the Holder thereof for Optional Exchange shall be irrevocable.
Unless otherwise provided in the applicable Supplement, the Optional Exchange
option may be exercised pursuant to this Section 4.07 by the Holder of a
Certificate for less than the aggregate Certificate Principal Balance or
Notional Amount of such Certificate as long as the Certificate Principal Balance
or Notional Amount remaining Outstanding after such Optional Exchange is an
Authorized Denomination and all other requirements set forth in the related
Supplement are satisfied. Upon such partial exchange, such Certificate shall be
cancelled and a new Certificate or Certificates for



<PAGE>


                                       39

the remaining Certificate Principal Balance or Notional Amount thereof shall be
issued (which shall be in the name of the Holder of such exchanged Certificate).

                  (c) Upon the completion of any such Optional Exchange, the
Trustee shall give prompt written notice thereof to each Rating Agency.

                  Section 4.08. Call Right. (a) The holder of a Call Right may
purchase Certificates of a given Series or Class from the Holders thereof prior
to maturity if the applicable Supplement designates such Series or Class as a
Callable Series, or upon the occurrence of a Tax Event or an Optional
Redemption. The Call Terms shall be set forth in the applicable Supplement and
shall include, without limitation, the following:

                  (i) the initial holder of the Call Right;

                  (ii) whether the Certificate Principal Balance or Notional
         Amount of each Certificate being purchased pursuant to the Call Right
         must be an Authorized Denomination;

                  (iii) the Call Date or Dates; and

                  (iv) the Call Price.

                  (b) A Call Right may be exercised at the option of the holder
thereof, in accordance with the Call Terms, upon not less than 35 days' (or such
shorter period acceptable to the Trustee or specified in the applicable
Supplement) nor more than 60 days' prior notice sent via facsimile with
transmission confirmed to the Trustee at the Corporate Trust Office. Such notice
to the Trustee shall include the Certificate Principal Balance (or Notional
Amount) of the Certificates to be purchased and shall reference the Call Price
and the Call Date. On or prior to the second Business Day following receipt of
such notice from the holder of the Call Right, the Trustee shall notify the
Holders of the Certificates by first class mail; such notices shall state:

                  (i)      the Certificate Principal Balance (or Notional
         Amount) of Certificates to be purchased;

                  (ii)     the Call Price;

                  (iii)    the name and address of the Paying Agent;

                  (iv) that Certificates called for purchase must be surrendered
         to the Paying Agent in order to collect the Call Price;




<PAGE>


                                       40

                  (v) that interest on Certificates called for purchase pursuant
         to the Call Right ceases to accrue on and after the Call Date, and the
         only remaining right of Holders of such Certificates is to receive
         payment of the Call Price upon surrender of the Certificates to the
         Paying Agent; and

                  (vi) that, if any Certificate contains a CUSIP, CINS or ISIN
         number, no representation is being made as to the correctness of the
         CUSIP, CINS or ISIN number either as printed on the Certificates or as
         contained in such notice and that reliance may be placed only on the
         other identification numbers printed on the Certificates.

                  (c) If less than all of the Certificates are to be purchased
pursuant to the exercise of the Call Right, the Trustee shall select the
Certificates to be purchased in accordance with the requirements of the
principal national securities exchange on which the Certificates are listed or,
if the Certificates are not listed on a national securities exchange, on a pro
rata basis, by lot or by such other method as such Trustee in its sole
discretion shall deem to be fair and appropriate. The Trustee shall notify the
Depositor and the Certificate Registrar promptly in writing of the Certificates
or portions of the Certificates to be purchased by the holder of the Call Right,
provided, however, that this Section 4.08(c) shall not apply to Certificates
subject to a Call Right due to a Tax Event or an Optional Redemption.

                  (d) Once such notice is mailed to the Holders, the
Certificates called for purchase become due and payable on the Call Date and at
the Call Price. Upon surrender of any Certificates to the Paying Agent, the
Holders of such Certificates shall be paid the Call Price. Notice of purchase
shall be deemed to be given when mailed, whether or not the Holder receives the
notice. In any event, failure to give such notice, or any defect therein, shall
not affect the validity of the proceedings for the purchase of Certificates held
by Holders to whom such notice was properly given.

                  (e) At or prior to 12:00 noon on the Call Date, the holder of
the Call Right to be exercised shall deposit with the Paying Agent by wire
transfer in same-day funds money sufficient to pay the Call Price of the
Certificates to be redeemed on that date.

                  (f) If a notice has been given in the manner provided above,
the Certificates or portion of Certificates specified in such notice to be
purchased shall become due and payable on the Call Date at the Call Price stated
therein, together with accrued interest (if applicable) on and after such dates.
Upon surrender of any Certificate in connection with the Call Right, such
Certificate shall be paid and redeemed by the holder of the Call Right at the
Call Price.

                                       41

                  (g) Upon surrender of any Certificate that is purchased in
part, the Depositor shall execute and the Trustee shall authenticate and deliver
to the Holder a new Certificate equal in principal amount to the unredeemed
portion of such surrendered Certificate.

                  (h) Notwithstanding anything to the contrary in these Standard
Terms or any Supplement, a Series or Class will be subject to a Call Right of
the Underlying Securities Issuer if the Underlying Securities Issuer gives
notice of a Tax Event or an Optional Redemption, regardless of whether such
Series or Class is also designated a Callable Series in the applicable
Supplement, and in the case of a Tax Event or an Optional Redemption the
required notice of the Call Right shall be the lesser of the time set forth in
Section 4.08(b) and the time set forth in the notice provisions relating to such
Tax Event or Optional Redemption, respectively, in the Underlying Securities
Indenture, as specified in the related Supplement.

                                THE CERTIFICATES

                  Section 5.01. The Certificates. (a) The Certificates of any
Series (or Class within such Series) shall be issued in fully registered form
without coupons and shall be substantially in the form of the exhibit attached
to the applicable Supplement.

                  (b) Each Series (and all Classes within such Series) shall be
created by a Supplement authorized by the Depositor and establishing the terms
and provisions of such Series. Each Trust must be a fixed investment trust under
the Code. Each such Series may be issued in one or more Classes, with such
further particular designation added or incorporated in such title for the
Certificates of any particular Series or Class within such Series as the
Depositor may determine. Each Certificate shall bear upon its face the
designation so selected for the Series and Class to which it belongs. All
Certificates of the same Series and Class shall be identical in all respects
except for the denominations thereof. All Certificates of all Classes within any
one Series at any time Outstanding shall be identical except for differences
among the Certificates of the different Classes within such Series specified in
the applicable Supplement. Except as otherwise provided in the related
Supplement, all Certificates of a particular Series (and all Classes within such
Series) issued under this Trust Agreement shall be in all respects equally and
ratably entitled to the benefits hereof without preference, priority or
distinction on account of the actual time or times of authentication and
delivery, all in accordance with the terms and provisions of this Trust
Agreement.

                  Section 5.02. Execution, Authentication and Delivery. (a) The
Certificates shall be executed by the Trustee by one of its Responsible
Officers, which may be in facsimile form and imprinted or otherwise reproduced
thereon. The signature of any of the Responsible Officers may be manual or
facsimile. Certificates bearing the manual or facsimile signature of individuals
who were at any time the Responsible Officers of the Trustee shall be binding,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Certificates.

                  (b) Each Certificate shall be dated as of the later of the
date specified in the related Supplement and the date of its authentication.

                  (c) No Certificate shall be entitled to any benefit under this
Trust Agreement or be valid or obligatory for any purpose, unless there appears
on such Certificate a certificate of authentication substantially in one of the
forms provided for herein executed by the Trustee by the manual signature of one
of its Responsible Officers, and such signature upon any Certificate shall be
conclusive evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder and is entitled to the benefits of this
Trust Agreement.

                  Section 5.03. Temporary Certificates. Pending the preparation
of Definitive Certificates or permanent Global Securities of any Series (or
Class within each such Series), and upon receipt of a Depositor Order, the
Trustee shall execute, authenticate and deliver temporary Certificates which are
printed, lithographed, typewritten, mimeographed or otherwise produced, in any
Authorized Denomination, substantially of the tenor of the Definitive
Certificates or permanent Global Securities in lieu of which they are issued, in
registered form and with such appropriate insertions, omissions, substitutions
and other variations as may be authorized by such Depositor Order. Any such
temporary Certificate may be in global form, representing all or a portion of
the Outstanding Certificates of such Series or Class. Every such temporary
Certificate shall be executed, authenticated and delivered by the Trustee upon
the same conditions and in substantially the same manner, and with the same
effect, as the Definitive Certificates or permanent Global Securities in lieu of
which is issued.

                  If temporary Certificates of any Series (or Class within such
Series) are issued, the Trustee will cause Definitive Certificates or Global
Securities of such Series or Class to be prepared without unreasonable delay.
After the preparation of Definitive Certificates of such Series or Class, the
temporary Certificates of such Series or Class shall be exchangeable for
Definitive Certificates or permanent Global Securities of such Series or Class
upon surrender of the temporary Certificates of such Series or Class at the
Corporate Trust Office, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Certificates of any Series or Class
within such Series, the Trustee, upon receipt of a Depositor Order, shall
execute, authenticate and deliver in exchange therefor Definitive

                                       43

Certificates or permanent Global Securities with a like Certificate Principal
Balance or Notional Amount, as applicable, of the same Series (or Class within
such Series) of Authorized Denomination and of like tenor. Until so exchanged,
temporary Certificates of any Series (or Class within such Series) shall in all
respects be entitled to the same benefits under this Trust Agreement as
Definitive Certificates or permanent Global Securities of such Series or Class,
except as otherwise specified in the applicable Supplement.

                  Upon any exchange of a portion of a temporary Global Security
for a permanent definitive Global Security or for the individual Definitive
Certificates represented thereby, the temporary Global Security shall be
endorsed by the Trustee to reflect the reduction of the aggregate Certificate
Principal Balance or Notional Amount, as applicable, evidenced thereby,
whereupon the aggregate Certificate Principal Balance or Notional Amount, as
applicable, of such temporary Global Security shall be reduced for all purposes
by the amount so exchanged and endorsed.

                  Section 5.04. Registration; Registration of Transfer and
Exchange. (a) The Trustee shall cause to be kept a register for each Series (the
registers maintained in such office and in any other office or agency of the
Trustee being herein sometimes collectively referred to as the "Certificate
Register") in which a transfer agent and registrar (which may be the Trustee)
(the "Certificate Registrar") shall provide for the registration of Certificates
and the registration of transfers and exchanges of Certificates. The Trustee is
hereby initially appointed Certificate Registrar for the purpose of registering
Certificates and transfers and exchanges of Certificates as herein provided;
provided, however, that the Trustee may appoint one or more co-Certificate
Registrars. Upon any resignation of any Certificate Registrar, the Depositor
shall promptly appoint a successor or, in the absence of such appointment,
assume the duties of Certificate Registrar.

                  If a Person other than the Trustee is appointed by the
Depositor as Certificate Registrar, the Depositor will give the Trustee prompt
written notice of the appointment of a Certificate Registrar and of the
location, and any change in the location, of the Certificate Register, and the
Trustee shall have the right to rely upon a certificate executed on behalf of
the Certificate Registrar by an Executive Officer thereof as to the names and
addresses of the Holders and the principal amounts and numbers of the
Certificates held by each Holder.

                  (b) Upon surrender for registration of transfer any
Certificate of any Series (or Class within such Series) at the office or agency
of the Trustee, if the requirements of Section 8-401(a) of the UCC are met to
the Depositor's satisfaction, the Depositor shall execute, and the Trustee, upon
receipt of a Depositor Order, shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Certificates of any
Authorized Denominations, of a like Series, Class and aggregate Certificate
Principal Balance or Notional Amount, as applicable.




<PAGE>


                                       44

                  (c) Notwithstanding any other provisions of this Section 5.04,
unless and until it is exchanged in whole or in part for the individual
Certificates represented thereby, a Global Security representing all or a
portion of the Certificates of a Series (or Class within such Series) may not be
transferred except as a whole by the Depository for such Series or Class 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 Depository for such Series or Class or a nominee of such
successor Depository.

                  (d) At the option of the Holder, Certificates of any Series
(or Class within such Series) (other than a Global Security, except as set forth
below) may be exchanged for other Certificates of the same Series or Class of
any Authorized Denomination of like tenor and aggregate Certificate Principal
Balance or Notional Amount, as applicable, upon surrender of the Certificates to
be exchanged at the office or agency of the Trustee maintained for such purpose.

                  (e) All Certificates issued upon any registration of transfer
or exchange of Certificates shall constitute complete and indefeasible evidence
of ownership in the Trust related to such Certificates and be entitled to the
same benefits under this Trust Agreement as the Certificates surrendered upon
such registration of transfer or exchange.

                  (f) Every Certificate presented or surrendered for
registration of transfer or exchange shall (if so required by the Depositor, the
Trustee or the Certificate Registrar) be duly endorsed, or be accompanied by a
written instrument of transfer in form satisfactory to the Depositor, the
Trustee or the Certificate Registrar, duly executed, by the Holder thereof or
his attorney duly authorized in writing, with such signature guaranteed by a
brokerage firm or financial institution that is a member of a Securities
Approved Medallion Program such as Securities Transfer Agents Medallion Program
(STAMP), Stock Exchange Medallion Program (SEMP) or New York Stock Exchange Inc.
Medallion Signature Program (MSP).

                  (g) No service charge shall be made to a Holder for any
registration of transfer or exchange of Certificates, but the Trustee may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or
exchange of Certificates, other than exchanges pursuant to Section 5.03 not
involving any transfer.

                  Section 5.05. Mutilated, Destroyed, Lost and Stolen
Certificates. If (i) any mutilated Certificate is surrendered to the Trustee at
its Corporate Trust Office or (ii) the Depositor and the Trustee receive
evidence to their satisfaction of the destruction, loss or theft of any
Certificate, and there is delivered to the Depositor and the Trustee such
security or indemnity as they may require to hold each of them and any Paying
Agent harmless, and



<PAGE>


                                       45

neither the Depositor nor the Trustee receives notice that such Certificate has
been acquired by a bona fide purchaser, then the Depositor shall execute and the
Trustee, upon receipt of a Depositor Order, shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Certificate, a new Certificate of the same Series or Class of like tenor, form,
terms and principal amount, bearing a number not contemporaneously Outstanding.
Any Certificate executed, authenticated and delivered under this Section 5.05 in
lieu of a lost, destroyed or stolen Certificate (a "Predecessor Certificate")
shall be deemed to evidence the same interest as the Predecessor Certificate.

                  Upon the issuance of any new Certificate under this Section
5.05, the Trustee may require the payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in respect thereto and any
other expenses (including the fees and expenses of the Trustee) connected
therewith.

                  Every new Certificate of any Series or Class issued pursuant
to this Section 5.05 shall constitute complete and indefeasible evidence of
ownership in the Trust related to such Series, whether or not the Predecessor
Certificate shall be at any time enforceable by anyone, and shall be entitled to
all the benefits of this Trust Agreement equally and proportionately with any
and all other Certificates of that Series or Class duly issued hereunder.

                  The provisions of this Section 5.05 are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of Predecessor Certificates.

                  Section 5.06. Persons Deemed Owners. (a) The Depositor, the
Trustee, the Securities Intermediary and any agent of the Depositor, the Trustee
or the Securities Intermediary may treat the Person in whose name any
Certificate is registered as the owner of such Certificate for the purpose of
receiving distributions of principal of (and premium, if any) and (subject to
Section 4.02) interest, if any, on such Certificate and for all other purposes
whatsoever, whether or not such Certificate be overdue, and neither the
Depositor, the Trustee or the Securities Intermediary, nor any agent of the
Depositor, the Trustee or the Securities Intermediary shall be affected by
notice to the contrary.

                  (b) None of the Depositor, the Trustee, the Securities
Intermediary or any of their agents will have any responsibility or liability
for any aspect of the records relating to or distributions made by the
Depository to Beneficial Owners of interests in a Global Security or for
maintaining, supervising or reviewing any records relating to such Beneficial
Owners.

                  Section 5.07. Cancellation. Unless otherwise specified
pursuant to Section 5.01 for Certificates of any Series, all Certificates
surrendered for payment, redemption,



<PAGE>


                                       46

transfer or exchange shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee and shall be promptly cancelled by the Trustee. No
Certificates shall be authenticated in lieu of or in exchange for any
Certificates cancelled as provided in this Section 5.07, except as expressly
permitted by this Trust Agreement.

                  Section 5.08. Global Securities. (a) If the Supplement
provides that a Series (or Class within such Series) of Certificates shall be
held by the Depository in book-entry form, then the Depositor shall execute and,
upon receipt of a Depositor Order, the Trustee shall authenticate and deliver
one or more Global Securities that (i) shall represent an aggregate initial
Certificate Principal Balance or Notional Amount, as applicable, equal to the
aggregate initial Certificate Principal Balance or Notional Amount, as
applicable, of the Certificates of such Series or Class to be represented by
such one or more Global Securities, (ii) shall be registered in the name of the
Depository for such Global Security or Securities or the nominee of such
Depository, (iii) shall be delivered by the Trustee to such Depository or
pursuant to such Depository's instruction and (iv) shall bear a legend
substantially to the following effect:

"UNLESS THIS GLOBAL SECURITY IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY
CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF A NOMINEE OF THE DEPOSITORY (AND
ANY PAYMENT IS MADE TO A NOMINEE OF THE DEPOSITORY), ANY TRANSFER, PLEDGE OR
OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH
AS THE REGISTERED OWNER HEREOF HAS AN INTEREST HEREIN.

UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR THE INDIVIDUAL
CERTIFICATES REPRESENTED HEREBY, THIS GLOBAL SECURITY MAY NOT BE TRANSFERRED
EXCEPT AS A WHOLE BY THE DEPOSITORY TO A NOMINEE OF THE DEPOSITORY OR BY A
NOMINEE OF THE DEPOSITORY TO THE DEPOSITORY OR TO ANOTHER NOMINEE OF THE
DEPOSITORY OR BY THE DEPOSITORY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITORY OR
A NOMINEE OF SUCH SUCCESSOR DEPOSITORY."

                  (b) No Holder of a Certificate of such Series or Class will
receive a Definitive Certificate representing such Holder's interest in such
Certificate or Certificates, except as provided in Section 5.10. Unless and
until Definitive Certificates have been issued to Holders of such Series or
Class pursuant to Section 5.10:

                  (i) the provisions of this Section 5.08 shall be in full force
         and effect;

                  (ii) the Certificate Registrar and the Trustee shall be
         entitled to deal with the Depository for all purposes of this Trust
         Agreement (including the distribution of



<PAGE>


                                       47

         principal of, and premium, if any, and interest on the Certificates and
         the giving of instructions or directions hereunder) as the sole Holder
         of the Certificates of such Series or Class, and shall have no
         obligation to the Beneficial Owners of interests in such Series or
         Class;

                  (iii) to the extent that the provisions of this Section 5.08
         conflict with any other provisions of this Trust Agreement, the
         provisions of this Section 5.08 shall control;

                  (iv) the rights of Beneficial Owners of such Series or Class
         shall be exercised only through the Depository and shall be limited to
         those established by law and agreements between such Beneficial Owners
         and the Depository or its Participants; and

                  (v) whenever this Trust Agreement requires or permits actions
         to be taken based upon instructions or directions of Holders of a
         specified percentage of the aggregate Voting Rights of a Series or
         Class, the Depository shall be deemed to represent such percentage only
         to the extent that it has received instructions to such effect from
         Beneficial Owners of such Series or Class or Participants in such
         Depository's system owning or representing, respectively, such required
         percentage of the beneficial interest in the Certificates of such
         Series or Class and has delivered such instructions to the Trustee.

                  (c) Each Depository for a Global Security must, at the time of
its designation and at all times while it serves as such Depository, be a
Clearing Agency registered under the Exchange Act and any other applicable
statute or regulation.

                  Section 5.09. Notices to Depository. Whenever a notice or
other communication to the Holders of a Series or Class within such Series
represented by one or more Global Securities is required under this Trust
Agreement, unless and until Definitive Certificates for such Series or Class
shall have been issued to such Beneficial Owners pursuant to Section 5.10, the
Trustee shall give all such notices and communications specified herein to be
given to Holders of the Certificates of such Series to the Depository, and shall
have no obligation to the Beneficial Owners.

                  Section 5.10. Definitive Certificates. (a) If in respect of a
Series (or Class within such Series) represented by one or more Global
Securities (i) the Depositor advises the Trustee and the Securities Intermediary
in writing that the Depository is no longer willing or able to properly
discharge its responsibilities with respect to the Certificates of such Series
or Class and the Depositor does not appoint a successor within 90 days or (ii)
the Depositor at its option advises the Trustee and the Securities Intermediary
in writing that it elects to terminate the book-entry system of such Series or
Class through the Depository, then the



<PAGE>


                                       48

Depository shall notify all Beneficial Owners or Participants in the
Depository's system with respect to such Series or Class and the Trustee of the
occurrence of any such event and of the availability of definitive, fully
registered Certificates ("Definitive Certificates") for such Series or Class to
Beneficial Owners of such Series or Class requesting the same.

                  Upon surrender to the Trustee of the Global Securities of such
Series or Class by the Depository, accompanied by registration instructions, the
Trustee upon receipt of a Depositor Order for the execution, authentication and
delivery of Definitive Certificates of such Series or Class, will execute,
authenticate and deliver Definitive Certificates of such Series or Class in an
aggregate Certificate Principal Balance or Notional Amount, as applicable, equal
to the aggregate Certificate Principal Balance or Notional Amount, as
applicable, of the Global Security or Securities representing Certificates of
such Series or Class in exchange for such Global Security or Securities. None of
the Depositor, the Certificate Registrar, the Trustee or the Securities
Intermediary shall be liable for any delay in delivery of such instructions and
may conclusively rely on, and shall be protected in relying on, such
instructions. Upon the exchange of a Global Security for Definitive
Certificates, such Global Security shall be cancelled by the Trustee. Definitive
Certificates issued in exchange for a Global Security shall be registered in
such names and in such Authorized Denominations as the Depository for such
Global Security, pursuant to instructions from its Participants, any indirect
participants or otherwise, shall instruct the Trustee. The Trustee shall deliver
such Certificates to the Person in whose names such Certificates are so
registered. Upon the issuance of Definitive Certificates of Series or Class, the
Trustee shall recognize the holders of the Definitive Certificates of such
Series or Class as Holders.

                  (b) In addition, if the Depositor so specifies with respect to
the Certificates of a given Series, a Beneficial Owner may, on terms acceptable
to the Depositor and the Depository for such Global Security, receive individual
Definitive Certificates in exchange for such beneficial interest. Upon the
request of such Beneficial Owner, the Trustee upon receipt of a Depositor Order
shall execute, authenticate and deliver, without service charge,

                  (i) to each such Person specified, a new individual
         Certificate or Certificates of the same Series or Class, of any
         Authorized Denomination as requested by such Person in an aggregate
         Certificate Principal Balance or Notional Amount, as applicable, equal
         to and in exchange for such Person's beneficial interest in the Global
         Security; and

                  (ii) to such Depository a new Global Security in an Authorized
         Denomination equal to the difference, if any, between the aggregate
         Certificate Principal Balance or Notional Amount, as applicable, of the
         surrendered Global Security and the aggregate Certificate Principal
         Balance or Notional Amount, as applicable, of individual Certificates
         delivered to Holders thereof.



<PAGE>


                                       49


                  In any exchange provided for above, the Trustee, upon receipt
of a Depositor Order, will execute, authenticate and deliver individual
Certificates in registered form in Authorized Denominations.

                  Section 5.11. Currency of Distributions. (a) Except as
otherwise specified pursuant to the applicable Supplement, distributions of the
principal of (and premium, if any) and interest in respect of Certificates of
any Series or Class will be made in Dollars.

                  (b) In the case of a Series denominated in a Specified
Currency other than the Dollar, all exchange rate calculations shall be based
upon the noon buying rate in New York City for cable transfers as certified for
customs purposes by the Fed for such Specified Currency. If the Fed does not
publish a noon buying rate for the applicable Specified Currency, the applicable
Supplement will designate the source for calculating the Dollar value of such
Specified Currency.

                  (c) With respect to any Series, any decision or determination
to be made regarding exchange rates shall be made by an Exchange Rate Agent,
provided, however, that such Exchange Rate Agent shall accept such appointment
in writing and the terms of such appointment shall be acceptable to the Trustee
and shall require such Exchange Rate Agent to make such determination by the
method provided in Section 5.11(b) for the making of such decisions or
determination. All decisions and determinations of such Exchange Rate Agent
regarding exchange rates shall be in its sole discretion and shall, in the
absence of manifest error, be conclusive for all purposes and irrevocably
binding upon the Depositor, the Trustee and all Holders of such Series.

                  (d) If distributions in respect of a Series must be made in a
Specified Currency other than Dollars and such currency is unavailable due to
the imposition of exchange controls or other circumstances beyond the control of
the Trustee and the Depositor or is no longer used by the government of the
country issuing such Specified Currency or is no longer commonly used for the
settlement of transactions by public institutions of or within the international
banking community, then all distributions in respect of such Series shall be
made in Dollars until such Specified Currency is available.

                  Section 5.12. Conditions of Execution, Authentication and
Delivery of New Series. (a) Certificates of a new Series may be issued at any
time and from time to time after the execution and delivery of these Standard
Terms and the related Supplement. The Trustee shall execute, authenticate and
deliver such Certificates upon a Depositor Order and upon delivery by the
Depositor to the Trustee of the following:

                  (i) The delivery of the Underlying Securities in accordance
         with Section 2.01(b);

                  (ii) An Opinion of Counsel to the Depositor, addressed to the
         Trustee, stating:



<PAGE>


                                       50


                  1. The Certificates are in the form contemplated by the Trust
         Agreement and assuming that the Certificates have been duly executed,
         authenticated and delivered by the Trustee in the manner described in
         its certificate delivered today, the Certificates are entitled to the
         benefits provided in the Trust Agreement and constitute valid and
         binding obligations of the Trust, enforceable against the Trust in
         accordance with their terms, except as the enforcement thereof may be
         limited by bankruptcy, insolvency (including, without limitation, all
         laws relating to fraudulent transfers), reorganization, moratorium or
         similar laws affecting enforcement of creditors' rights generally and
         except as enforcement thereof is subject to general principles of
         equity (regardless of whether enforcement is considered in a proceeding
         in equity or at law), and will be entitled to the benefits of the Trust
         Agreement.

                  2. Execution, authentication and delivery of such Certificates
         by the Trustee will not violate the terms of the Trust Agreement.

                  3. The execution and delivery of the Trust Agreement will not
         contravene the certificate of incorporation or by-laws of the Company
         or result in any violation of any of the terms or provisions of any law
         or regulation or, to our knowledge of any indenture, mortgage or other
         agreement by which the Company is bound.

                  4. The Trust Agreement has been duly authorized, executed and
         delivered by the Company and (assuming the due authorization, execution
         and delivery thereof by the Trustee and the Securities Intermediary)
         constitutes a legal, valid and binding obligation of the Company
         enforceable against the Company in accordance with its terms, except as
         enforcement thereof may be limited by bankruptcy, insolvency
         (including, without limitation, all laws relating to fraudulent
         transfers), reorganization, moratorium or other similar laws affecting
         enforcement of creditors' rights generally and except as enforcement
         thereof is subject to general principles of equity (regardless of
         whether enforcement is considered in a proceeding in equity or at law).

         (iii) An Officer's Certificate of the Depositor, dated as of the
Closing Date, to the effect that all of the requirements of this Section 5.12
have been satisfied, and that the Depositor is not in breach of this Trust
Agreement and that the execution and delivery of this Trust Agreement and the
Certificates will not result in any breach of any of the terms, conditions, or
provisions of, or constitute a default under, the Depositor's certificate of
incorporation and by-laws, or any indenture, mortgage, deed of transfer or other
agreement or instrument to which the Depositor is a party or by which it or its
property is bound or any order of any court or administrative agency entered in
any Proceeding to which the Depositor is a party or by which it or its property
may be bound or to which it or its property may be subject;




<PAGE>


                                       51

         (iv) A Supplement consistent with the applicable provisions of these
Standard Terms;

         (v) All agreements, instruments or other documents called for by the
applicable Supplement as a condition to the issuance of the Certificates of such
Series;

         (vi) If applicable, a fully executed copy of any Swap Agreement or
other Credit Support Instrument, together with all documents and opinions
required to be delivered to the Trust upon execution thereof pursuant to the
terms thereof; and

         (vii) Written instructions by the Depositor to the Trustee directing
the Trustee to enter into and perform any obligations under any Swap Agreement
or other Credit Support Instrument, if applicable, and/or the Market Agent
Agreement, if applicable.

         (b) If all the Certificates of a Series are not to be originally issued
at the same time, then the documents required to be delivered pursuant to this
Section 5.12 must be delivered only once, prior to the authentication and
delivery of the first Certificate of such Series; provided, however, that any
subsequent Depositor Order to the Trustee to authenticate Certificates of such
Series upon original issuance shall constitute a representation and warranty by
the Depositor that, as of the date of such request, the statements made in this
Section 5.12 shall be true and correct as if made on such date.

                  Section 5.13. Appointment of Paying Agent. The Trustee may
appoint one or more paying agents (each, a "Paying Agent") with respect to the
Certificates of any Series. Any such Paying Agent shall be authorized to make
distributions to Certificateholders of such Series from the Certificate Account
for such Series pursuant to the provisions of the Supplement and shall report
the amounts of such distributions to the Trustee. Any Paying Agent shall have
the revocable power to withdraw funds from such Certificate Account for the
purpose of making the distributions referred to above. The Trustee may revoke
such power and remove the Paying Agent if the Trustee determines in its sole
discretion that the



<PAGE>


                                       52

Paying Agent shall have failed to perform its obligations under this Trust
Agreement in any material respect; provided, however, no Paying Agent may be
removed or replaced until a successor (which successor may be the Trustee) has
been appointed as provided for herein and has accepted the appointment. The
Paying Agent shall initially be the Trustee and any co-paying agent chosen by
the Trustee and acceptable to the Depositor, including, if and so long as any
Series or Class within such Series is listed on the Luxembourg Stock Exchange
and such exchange so requires, a co-paying agent in Luxembourg or another
European city, as specified in the related Supplement. Any Paying Agent shall be
permitted to resign as Paying Agent upon 30 days' notice to the Trustee. In the
event that the Trustee shall no longer be the Paying Agent, the Trustee shall
appoint a successor or additional Paying Agent. The Trustee shall cause each
successor to act as Paying Agent to execute and deliver to Trustee an instrument
in which such successor or additional Paying Agent shall agree with



<PAGE>


                                       53

the Trustee that it will hold all sums, if any, held by it for distribution to
the Certificateholders in trust for the benefit of the Certificateholders
entitled thereto until such sums shall be distributed to such Certificateholders
and will agree to such other matters as are required by TIA Section 317(b). The
Paying Agent shall return all unclaimed funds to the Trustee and upon removal
shall also return all funds in its possession to the Trustee. The provisions of
Sections 7.01, 7.03, 7.04 and 7.06 shall apply to the Trustee also in its role
as Paying Agent, for so long as the Trustee shall act as Paying Agent. Any
reference in this Trust Agreement to the Paying Agent shall include any
co-paying agent unless the context requires otherwise. Notwithstanding anything
contained herein to the contrary, the appointment of a Paying Agent pursuant to
this Section 5.13 shall not release the Trustee from the duties, obligations,
responsibilities or liabilities arising under this Trust Agreement other than
with respect to funds paid to such Paying Agent.

                  Section 5.14. Authenticating Agent. (a) The Trustee may
appoint one or more Authenticating Agents (each, an "Authenticating Agent") with
respect to the Certificates of any Series which shall be authorized to act on
behalf of the Trustee in authenticating such Certificates in connection with the
issuance, delivery and registration of transfer or exchange of such
Certificates. Whenever reference is made in this Trust Agreement to the
authentication of Certificates by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication on
behalf of the Trustee by an Authenticating Agent and a certificate of
authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent must be acceptable to the Depositor. Notwithstanding
anything contained herein to the contrary, the appointment of an Authenticating
Agent pursuant to this Section 5.14 shall not release the Trustee from the
duties, obligations, responsibilities or liabilities arising under this Trust
Agreement.

                  (b) Any institution succeeding to the corporate agency
business of any Authenticating Agent shall continue to be an Authenticating
Agent without the execution or filing of any power or any further act on the
part of the Trustee or such Authenticating Agent. An Authenticating Agent may at
any time resign by giving notice of resignation to the Trustee and to the
Depositor. The Trustee may at any time terminate the agency of an Authenticating
Agent by giving notice of termination to such Authenticating Agent and to the
Depositor. Upon receiving such a notice of resignation or upon such a
termination, or in case at any time an Authenticating Agent shall cease to be
acceptable to the Trustee or the Depositor, the Trustee promptly may appoint a
successor Authenticating Agent which may be the Trustee. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with
like effect as if originally named as an Authenticating Agent. No successor
Authenticating Agent shall be appointed unless acceptable to the Depositor. The
Trustee agrees to pay to each Authenticating Agent from time to time reasonable
compensation for its services under this Section. The provisions of Sections
7.01, 7.03 and 7.04 shall be applicable to any Authenticating Agent.

                  (c) Pursuant to an appointment made under this Section, the
Certificates may have endorsed thereon, in lieu of the Trustee's certificate of
authentication, an alternate certificate of authentication in substantially the
following form:

                  "This is one of the Certificates described in the Standard
Terms and the related Supplement.

                  Dated:          [NAME OF AUTHENTICATING AGENT]
                                           as Authenticating Agent
                                                for the Trustee,


                                           By:
                                               ---------------------------------
                                                    Authorized Officer"

                  Section 5.15. Voting Rights with Respect to Underlying
Securities. (a) Within five Business Days after receipt of notice of any meeting
of, or other occasion for the exercise of voting rights or the giving of
consents by owners of any of the Underlying Securities, the Trustee shall give
notice to the Holders, setting forth (i) such information as is contained in
such notice to owners of Underlying Securities, (ii) a statement that Holders
will be entitled, subject to any applicable provision of law and any applicable
provisions of such Underlying Securities to instruct the Trustee as to the
exercise of Voting Rights, if any, pertaining to such Underlying Securities and
(iii) a statement as to the manner in which instructions may be given to the
Trustee to give a discretionary proxy to a person designated in the notice
received by the Trustee. Such notice shall be given by the Trustee to the
Holders of record on such Record Date.

                  Upon the written request of the applicable Holder, received on
or before the date established by the Trustee for such purpose, the Trustee
shall endeavor, insofar as practicable and permitted under any applicable
provision of law and any applicable provision of or governing the Underlying
Securities, to vote in accordance with any nondiscretionary instruction set
forth in such written request. The Trustee shall not vote except as specifically
authorized and directed in written instructions from the applicable Holder
entitled to give such instructions. Notwithstanding the foregoing, if the
Trustee determines (based solely upon advice furnished by nationally recognized
independent tax counsel, whether at the request of any Holder or otherwise) that
the exercise of voting rights with respect to any Underlying Securities could
result in a "sale or other disposition" of such Underlying Securities within the
meaning of Section 1001(a) of the Code, as amended, the Trustee shall exercise
such voting rights in a manner that would not result in any such sale or other
disposition. The Trustee will have no responsibility to undertake on its own
initiative to determine that any exercise of voting rights will result in any
such sale or other disposition.

                  (b) By accepting delivery of a Certificate, whether upon
original issuance or subsequent transfer, exchange or replacement thereof, and
without regard to whether ownership is beneficial or otherwise, the Holder
agrees so long as it is an owner thereof that it shall not grant any consent (i)
to any conversion of the timing of payment of, or the method or rate of
accruing, interest on the Underlying Securities underlying the Certificates held
by such Holder or (ii) to any redemption or prepayment of the Underlying
Securities underlying the Certificates held by such Holder. The Trustee shall
not grant any consent solicited from the owners of the Underlying Securities
underlying the Certificates with respect to the matters set forth in this
Section nor shall it accept or take any action in respect of any consent, proxy
or instructions received from any Holder in contravention of the provisions of
this Section.

                  Section 5.16. Actions by Certificateholders. (a) Wherever in
this Trust Agreement a provision is made that an action may be taken or a
notice, demand or instruction given by Certificateholders or Beneficial Owners,
such action, notice or instruction may be taken or given by any
Certificateholder or Beneficial Owner.

                  (b) Each Certificateholder or Beneficial Owner shall have the
right to assert any rights and privileges of a Certificateholder or Beneficial
Owner, and shall have the right to proceed directly and individually against any
Person to enforce any remedies hereunder and shall not be required to act in
concert with any other Certificateholder or Beneficial Owner or any other
Person.

                  (c) Any request, demand, authorization, direction, notice,
consent, waiver or other act by a Certificateholder or Beneficial Owner of a
Certificate shall bind such Certificateholder or Beneficial Owner and every
subsequent Certificateholder or Beneficial Owner of such Certificate or any
Certificate issued upon the registration of transfer thereof or in exchange
therefor or in lieu thereof in respect of anything done, suffered or omitted to
be done by the Certificateholder or Beneficial Owner or the Trustee in reliance
thereon, whether or not notation of such action is made upon such Certificate.

                  (d) Holders are beneficial owners of the right to receive
principal payments and interest payments to which such Certificates relate and,
as such, will have the right following an event of default with respect to any
Underlying Security to proceed directly against the Underlying Securities
Issuer(s). Such Certificateholders are not required to join other Holders of
Certificates, the Depositor, the Trustee or the Securities Intermediary in order
to proceed against the Underlying Securities Issuer(s).

                  Section 5.17. Events of Default. If any Event of Default shall
occur and be continuing with respect to any Class of Certificates, then, and in
each and every case, the Trustee shall exercise any rights in respect of the
related Underlying Securities as provided in the applicable Supplement.

                  Section 5.18. Judicial Proceedings Instituted by Trustee;
Trustee May Bring Suit. If there shall be a failure to make payment of the
principal of or premium, if any, or interest on any Underlying Security, then
the Trustee, in its own name, and as trustee of an express trust, as holder of
such Underlying Security, shall be, to the extent permitted by and in accordance
with the terms of the Underlying Security, subject to the limitations on
acceleration and the exercise of remedies set forth therein, and further subject
to the provisions of Sections 7.01(c) and 7.06(f) herein, entitled and empowered
to institute Proceedings at law, in equity or otherwise, including the power to
make a demand on the trustee in respect of such Underlying Security, if provided
for, to take action to enforce the Underlying Security for the collection of the
sums so due and unpaid on such Underlying Security and may prosecute any such
Proceeding to judgment or final decree with respect to the whole amount of any
such sums so due and unpaid.

                  Section 5.19. Control by Certificateholders. The Holders of
Certificates of any Class holding Certificates representing not less than the
Required Percentage--Direction of Trustee of the aggregate Voting Rights of the
Outstanding Certificates of such Class shall have the right to direct the time,
method and place of conducting any Proceeding for any remedy available to the
Trustee or exercising any trust or power conferred on the Trustee under this
Trust Agreement, including any right of the Trustee as holder of the Underlying
Securities; provided that:

                  (i) such direction shall not be in conflict with any rule of
         law or with this Trust Agreement and would not involve the Trustee in
         personal liability or expense;

                  (ii) the Trustee shall determine, based upon an Opinion of
         Counsel, that the action so directed would not be unjustly prejudicial
         to the Holders of Certificates of such Class not taking part in such
         direction; and

                  (iii) the Trustee may take any other action deemed proper by
         the Trustee which is not inconsistent with such direction.

                  Section 5.20. Waiver of Past Defaults. The Holders of the
Required Percentage--Waiver of Certificates of any Series may (a) waive any past
default under this Trust Agreement and its consequences or (b) direct the
Trustee to vote such percentage of the Underlying Securities held by the Trustee
as corresponds to the percentage of the aggregate Principal Amount of the
Certificates of such Series held by such Holders to waive any past default
thereunder and its consequences with respect to such Series; provided that such
Holders may not waive or direct the Trustee to waive a default

                  (i) in the payment of the principal of or premium, if any, or
         interest on the Underlying Securities; or

                                       57

                  (ii) in respect of a covenant or provision hereof that under
         Section 11.01 hereof cannot be modified or amended without the consent
         of the Holder of each Outstanding Certificate affected.

Upon any waiver of a default under this Trust Agreement or direction that is
effective to waive a default in respect of the Underlying Securities, such
default shall cease to exist with respect to this Trust Agreement, any Event of
Default arising therefrom shall be deemed to have been cured for every purpose
of this Trust Agreement and any direction given by the Trustee on behalf of such
Holders in respect of any Underlying Securities shall be annulled with respect
thereto; but no such waiver shall extend to any subsequent or other default or
Event of Default or impair any right consequent thereon.

                  Section 5.21. Right of Certificateholders to Receive Payments
Not to Be Impaired. Anything in this Trust Agreement to the contrary
notwithstanding, the right of any Certificateholder to receive distributions of
payments required pursuant to Section 4.01 hereof on the Certificates when due,
or to institute suit for enforcement of any such payment on or after the
applicable Distribution Date or other date specified herein for the making of
such payment, shall not be impaired or affected without the consent of such
Certificateholder.

                  Section 5.22. Remedies Cumulative. Every remedy given
hereunder to the Trustee or to any of the Certificateholders shall not be
exclusive of any other remedy or remedies, and every such remedy shall be
cumulative and in addition to every other remedy given hereunder or now or
hereafter given by statute, law, equity or otherwise.


                                   ARTICLE VI

                                  THE DEPOSITOR

                  Section 6.01. Liability of the Depositor. The Depositor shall
be liable in accordance herewith only to the extent of the obligations
specifically imposed by these Standard Terms and the related Supplement.

                  Section 6.02. Limitation on Liability of the Depositor. (a)
The Depositor shall not be under any obligation to expend or risk its own funds
or otherwise incur financial liability in the performance of its duties
hereunder or under a Supplement or in the exercise of any of its rights or
powers if reasonable grounds exist for believing that the repayment or such
funds or adequate indemnity against such risk or liability is not reasonably
assured to it.

                  (b) Neither the Depositor nor any of its directors, officers,
employees or agents shall be under any liability to any Trust or the
Certificateholders of any Series for any

                                       58

action taken, or for refraining from the taking of any action, in good faith
pursuant to this Trust Agreement, or for errors in judgment; provided, however,
that this provision shall not protect the Depositor against any breach of
representations, warranties or covenants made herein, or against any liability
which would otherwise be imposed by reason of willful misfeasance, bad faith or
negligence in the performance of duties or by reason of reckless disregard of
obligations and duties hereunder.

                  (c) The Depositor shall not be under any obligation to appear
in, prosecute or defend any legal action unless such action is related to its
respective duties under this Trust Agreement and, in its opinion, does not
involve it in any expense or liability; provided, however, that the Depositor
may in its discretion undertake any such action which it may deem necessary or
desirable with respect to this Trust Agreement and the rights and duties of the
parties hereto and the interests of the Certificateholders hereunder. The
Depositor shall be under no obligation whatsoever to appear in, prosecute or
defend any action, suit or other Proceeding in respect of any Underlying
Securities.

                  (d) The Depositor shall not be liable to any Certificateholder
for any action or non-action by it in reliance upon the advice of or information
from legal counsel, accountants, and a Certificateholder of a Certificate or any
other person believed by it in good faith to be competent to give such advice or
information, including, without limitation, the Market Agent or the other
parties to this Trust Agreement. The Depositor may rely and shall be protected
in acting upon any written notice, request, direction or other document believed
by it to be genuine and to have been signed or presented by the proper party or
parties.

                  (e) The Depositor shall not incur any liability to any
Certificateholder if, by reason of any provision of any present or future law,
or regulation thereunder, or any governmental authority, or by any reason of any
act of God or war or other circumstance beyond the control of the relevant
party, the Depositor shall be prevented or forbidden from doing or performing
any act or thing which the terms of this Trust Agreement provide shall be done
or performed; and the Depositor shall not incur any liability to any
Certificateholder by reason of any non-performance or delay, caused as
aforesaid, in the performance of any act or thing which the terms of this Trust
Agreement provide shall or may be done or performed, or by reason of any
exercise of, or failure to exercise, any discretion provided for in this Trust
Agreement.

                  Section 6.03. Depositor May Purchase Certificates. The
Depositor may at any time purchase Certificates in the open market or otherwise.
Certificates so purchased by the Depositor may, at the discretion of the
Depositor, be held or resold. Certificates beneficially owned by the Depositor
will be disregarded for purposes of determining whether the required percentage
of the aggregate Voting Rights has given any request, demand, authorization,
direction, notice, consent or waiver hereunder.

                  Section 6.04. Merger or Consolidation of the Depositor.
Nothing in this Trust Agreement shall prevent any consolidation or merger of the
Depositor with or into any other corporation, or any consolidation or merger of
any other corporation with or into the Depositor or any sale or transfer of all
or substantially all of the property and assets of the Depositor to any other
Person lawfully entitled to acquire the same; provided, however, that, so long
as Certificates are outstanding hereunder, the Depositor covenants and agrees
that any such consolidation, merger, sale or transfer shall be upon the
condition that the due and punctual performance and observance of all the terms,
covenants and conditions of this Trust Agreement to be kept or performed by the
Depositor shall be assumed by the Person (if other than the Depositor) formed by
or resulting from any such consolidation or merger, or which shall have received
the transfer of all or substantially all of the property and assets of the
Depositor, just as fully and effectually as if successor Person had been the
original party of the first part hereto; and in the event of any such sale or
transfer the predecessor Depositor may be dissolved, wound up and liquidated at
any time thereafter.

                  Section 6.05. No Liability of the Depositor with Respect to
the Underlying Securities; Certificateholders to Proceed Directly Against the
Underlying Securities Issuer(s). (a) The sole obligor with respect to any
Underlying Security is the Underlying Securities Issuer(s). The Depositor shall
not have any obligation on or with respect to the Underlying Securities; and its
obligations with respect to Certificates shall be solely as set forth in this
Trust Agreement.

                  (b) The Depositor is not authorized to proceed against the
Underlying Securities Issuer in the event of a default or to assert the rights
and privileges of Certificateholders and has no duty in respect thereof.


                                   ARTICLE VII

                                   THE TRUSTEE

                  Section 7.01. Duties of Trustee. (a) The Trustee undertakes to
perform such duties and only such duties as are specifically set forth in these
Standard Terms and the related Supplement. The Trustee shall exercise in case of
receipt of notice of Default (as such term is defined in paragraph (d) below)
such of the rights and powers vested in it by this Trust Agreement, and shall
use the same degree of care and skill in their exercise, as a prudent person
would exercise or use under the circumstances in the conduct of such person's
own affairs. In the event that the Underlying Securities Issuer ceases to file
periodic reports under the Exchange Act, the Depositor shall notify the Trustee
of that fact and the Trustee shall take such actions as specifically set forth
in the Supplement. The Trustee shall exercise those rights in a manner
consistent with the status of any Trust created hereunder as a fixed investment
trust for federal income tax purposes as directed by the



<PAGE>


                                       60

Depositor. The Trustee shall not have any power to vary the investment of any
Certificateholders of any Series or to accept any assets (other than proceeds of
the Underlying Securities) other than the Underlying Securities transferred to
it on the Closing Date of any Series. Any permissive right of the Trustee
enumerated in this Trust Agreement shall not be construed as a duty and shall be
interpreted consistently with the status of the Trust as a fixed investment
trust.

                  (b) The Trustee, upon receipt of all resolutions,
certificates, statements, opinions, reports, documents, orders or other
instruments furnished to the Trustee which are specifically required to be
furnished pursuant to any provision of this Trust Agreement, shall examine them
to determine, in its best judgment, whether they conform to the requirements of
this Trust Agreement. If any such instrument is found not to conform to the
requirements of this Trust Agreement, the Trustee shall take action as it deems
appropriate to have the instrument corrected, and if the instrument is not
corrected to the Trustee's satisfaction, the Trustee will provide notice thereof
to the Depositor and Certificateholders.

                  (c) No provision of this Trust Agreement shall be construed to
relieve the Trustee from liability for its own negligent action, its own
negligent failure to act or its own misconduct; provided, however, that:

                  (i) the duties and obligations of the Trustee shall be
         determined solely by the express provisions of this Trust Agreement,
         the Trustee shall not be liable except for the performance of such
         duties and obligations as are specifically set forth in this Trust
         Agreement, no implied covenants or obligations shall be read into this
         Trust Agreement against the Trustee and, in the absence of bad faith on
         the part of the Trustee, the Trustee may conclusively rely, as to the
         truth of the statements and the correctness of the opinions expressed
         therein, upon any certificates or opinions furnished to the Trustee
         that conform to the requirements of this Trust Agreement;

                  (ii) the Trustee shall not be personally liable for an error
         of judgment made in good faith by a Responsible Officer or Responsible
         Officers of the Trustee, unless it shall be proved that the Trustee was
         negligent in ascertaining the pertinent facts;

                  (iii) the Trustee shall not be personally liable with respect
         to any action taken, suffered or omitted to be taken by it in good
         faith in accordance with the direction of Holders of the Required
         Percentage--Direction of Trustee of the aggregate Voting Rights of a
         given Series (or Class or group of Classes within such Series), as
         specified in the applicable Supplement relating to the time, method and
         place of conducting any Proceeding for any remedy available to the
         Trustee, or exercising any trust or power conferred upon the Trustee,
         under this Trust Agreement;

                                       61

                  (iv) the Trustee shall not be required to expend or risk its
         own funds or otherwise incur financial liability in the performance of
         any of its duties hereunder or in the exercise of any of its rights or
         powers if there is reasonable ground for believing that the repayment
         of such funds or adequate indemnity against such risk or liability is
         not reasonably assured to it;

                  (v) except for actions expressly authorized by this Trust
         Agreement, the Trustee shall take no actions reasonably likely to
         impair the interests of the Trust in any Underlying Security now
         existing or hereafter acquired or to impair the value of any Underlying
         Security now existing or hereafter acquired;

                  (vi) except as expressly provided in this Trust Agreement, the
         Trustee shall have no power to vary the corpus of the Trust including
         by (A) accepting any substitute obligation or asset for an Underlying
         Security initially assigned to the Trustee under Section 2.01, (B)
         adding any other investment, obligation or security to the Trust or (C)
         withdrawing from the Trust any Underlying Securities;

                  (vii) in the event that the Paying Agent or the Certificate
         Registrar shall fail to perform any obligation, duty or agreement in
         the manner or on the day required to be performed by the Paying Agent
         or Certificate Registrar, as the case may be, under this Trust
         Agreement, the Trustee shall be obligated promptly upon its knowledge
         thereof to perform such obligation, duty or agreement in the manner so
         required;

                  (viii) the Trustee shall not be liable to any
         Certificateholder for any action or non-action by it in reliance upon
         the advice of or information from legal counsel, accountants, any
         Certificateholder or any other person believed by it in good faith to
         be competent to give such advice or information, including, without
         limitation, the Market Agent or the other parties to this Trust
         Agreement. The Trustee may rely and shall be protected in acting upon
         any written notice, facsimile transmission, request, direction or other
         document believed by it to be genuine and to have been signed or
         presented by the proper party or parties;

                  (ix) the Trustee shall not incur any liability to any
         Certificateholder if, by reason of any provision of any present or
         future law, or regulation thereunder, or any governmental authority, or
         by any reason of any act of God or war or other circumstance beyond the
         control of the relevant party, the Trustee shall be prevented or
         forbidden from doing or performing any act or thing which the terms of
         this Trust Agreement provide shall be done or performed; and the
         Trustee shall not incur any liability to any Certificateholder by
         reason of any non-performance or delay, caused as aforesaid, in the
         performance of any act or thing which the terms of this Trust Agreement
         provide shall or may be done or performed, or by reason of any exercise
         of, or failure to exercise, any discretion provided for in this Trust
         Agreement;

                                       62


                  (x) the Trustee shall be under no obligation whatsoever to
         appear in, prosecute or defend any Proceeding in respect of any
         Underlying Securities;

                  (xi) whenever in the administration of this Trust Agreement
         the Trustee shall deem it desirable that a matter be proved or
         established prior to taking, suffering or omitting any action
         hereunder, the Trustee (unless other evidence be herein specifically
         prescribed) may, in the absence of bad faith on its part, conclusively
         rely upon an Officers' Certificate; and

                  (xii) the Trustee may consult with counsel of its selection
         and, the advice of such counsel or any Opinion of Counsel selected by
         the Trustee with due care shall be full and complete authorization and
         protection in respect of any action taken, suffered or omitted by it
         hereunder in reliance thereon.

                  (d) As promptly as practicable after, and in any event within
10 days after, the occurrence of any Default (as such term is defined below)
hereunder with respect to any Class of Certificates, the Trustee shall transmit
by mail to the Depositor and the Holders of Certificates of such Class in
accordance with TIA Section 313(c), notice of such Default hereunder actually
known to the Trustee, unless such Default shall have been cured or waived;
provided, however, that, except in the case of a Default in the payment of the
principal of or premium, if any, or interest on any Underlying Security, the
Trustee shall be protected in withholding such notice if and so long as a trust
committee of Responsible Officers of the Trustee in good faith determines that
the withholding of such notice is in the interests of the Holders of the
Certificates of such Class. For the purpose of this Section 7.01(d), the term
"Default" means, with respect to any Class of Certificates, any event that is,
or after notice or lapse of time or both would become, an Event of Default with
respect to such Class of Certificates.

                  (e) Within five (5) Business Days after the receipt by the
Trustee of a written application by any three or more Certificateholders stating
that such Certificateholders desire to communicate with other Certificateholders
with respect to their rights under this Trust Agreement or under the
Certificates, and accompanied by a copy of the form of proxy or other
communication which such Certificateholders propose to transmit, and by
reasonable proof that each such Certificateholder has owned its Certificates for
a period of at least six (6) months preceding the date of such application, the
Trustee shall, at its election, either:

                  (i) afford to such Certificateholders access to all
         information so furnished to or received by the Trustee; or

                  (ii) inform such Certificateholders as to the approximate
         number of



<PAGE>


                                       63

         Certificateholders according to the most recent information so
         furnished to or received by the Trustee, and as to the approximate cost
         of mailing to such Certificateholders the form of proxy or other
         communication, if any, specified in such application.

If the Trustee shall elect not to afford to such Certificateholders access to
such information, the Trustee shall, upon the written request of such
Certificateholders, mail to all such Certificateholders copies of the form of
proxy or other communication which is specified in such request, with reasonable
promptness after a tender to the Trustee of the material to be mailed and of
payment, or provision for the payment, of the reasonable expenses of such
mailing.

                  (f) The Trustee shall prepare for filing, at the direction of
and with information provided by the Depositor, periodic reports for the Trust
pursuant to the Exchange Act, and the rules and regulations promulgated
thereunder on behalf of the Depositor. The Depositor shall respond reasonably
promptly to any inquiry of the Trustee concerning such reports and shall provide
the information required for such reports within three days of the filing due
date.

                  Section 7.02. Agreements Between Trustee and Administrative
Agents. (a) The Trustee may enter into Administration Agreements with one or
more Administrative Agents in order to delegate to such Administrative Agents
certain of its administrative obligations with respect to a Series hereunder;
provided, however, that:

                  (i) such delegation shall not release the Trustee from the
         duties, obligations, responsibilities or liabilities arising hereunder;

                  (ii) the Rating Agency Condition shall have been satisfied
         with respect to the entering into of any such agreement;

                  (iii) such agreement must be consistent with these Standard
         Terms and, with respect to Certificates of any Series, the related
         Supplement;

                  (iv) the Trustee will remain solely liable for all fees and
         expenses it may owe to such Administrative Agent;

                  (v) the Administrative Agent shall give representations and
         warranties in such Administration Agreement that are the same in
         substance as those set forth in Section 7.10 herein (references therein
         to the Trust Agreement, the Trustee and the Depositor shall be to the
         applicable Administration Agreement, Administrative Agent and Trustee,
         respectively, for purposes of this Section 7.02(a)); and




<PAGE>


                                       64

                  (vi) such Administrative Agent shall meet the eligibility
         requirements of a Trustee pursuant to Section 7.07 herein.

An Administration Agreement must provide that an entity serving as
Administrative Agent may resign from its obligations and duties under this Trust
Agreement with respect to any Series only if such resignation, and the
appointment of a successor, would satisfy the Rating Agency Condition or upon a
determination that the duties of the Administrative Agent with respect to such
Series are no longer permissible under applicable law. No such resignation shall
become effective until the Trustee or a successor Administrative Agent has
assumed the obligations of such Administrative Agent with respect to such
Series. In addition, with respect to any Series (or Class within such Series),
each Administration Agreement shall impose on the Administrative Agent
requirements conforming to the provisions set forth in Section 3.01 and provide
for administration of the related Trust and all or certain specified Underlying
Securities for such Series consistent with the terms of this Trust Agreement.
Additional requirements relating to the scope and contents of any Administration
Agreement may be provided in the applicable Supplement. The Trustee shall
deliver to the Depositor copies of all Administration Agreements into which it
enters, and any amendments or modifications thereof, promptly upon the Trustee's
execution and delivery of any such instruments.

                  (b) Upon the occurrence of an Administrative Agent Termination
Event, the Trustee shall be entitled to terminate the relevant Administration
Agreement and the rights and obligations of any such Administrative Agent under
any Administration Agreement in accordance with the terms and conditions of any
such Administration Agreement. If such Administration Agreement is terminated,
the Trustee shall simultaneously reassume direct responsibility for all
obligations delegated in such Administration Agreement without any act or deed
on the part of the applicable Administrative Agent, and the Trustee shall
administer directly the related Underlying Securities or shall enter into an
Administration Agreement with a successor Administrative Agent which so
qualifies under Section 7.02(a). If the Trustee is unwilling or unable to act,
it may appoint, or petition a court of competent jurisdiction for the
appointment of, an Administrative Agent which so qualifies under Section
7.02(a). Pending such appointment, the Trustee must act in such capacity (except
that if the Trustee is prohibited by law from doing so, then the Trustee will
not be so obligated).

                  (c) If an Administrative Agent is administering one or more
Underlying Securities pursuant to an Administration Agreement, the
Administrative Agent shall deposit into an Eligible Account established by such
Administrative Agent (an "Administration Account") any amounts collected with
respect thereto, and all such amounts shall be distributed to the Trustee for
deposit into the related Certificate Account not later than the Business Day
after receipt thereof.

                  Section 7.03. Certain Matters Affecting the Trustee. (a)
Except as otherwise provided in this Article VII:

                  (i) the Trustee may request and rely upon and shall be
         protected in acting or refraining from acting upon any resolution,
         Officer's Certificate, certificate of auditors or any other
         certificate, statement, instrument, opinion, report, notice, facsimile
         transmission, request, consent, order, appraisal, bond or other paper
         or document reasonably believed by it to be genuine and to have been
         signed or presented by the proper party or parties;

                  (ii) the Trustee may consult with counsel and any Opinion of
         Counsel shall be full and complete authorization and protection in
         respect of any action taken or suffered or omitted by it hereunder in
         good faith and in accordance with such Opinion of Counsel;

                  (iii) the Trustee shall be under no obligation to exercise any
         of the trusts or powers vested in it by this Trust Agreement or to
         institute, conduct or defend any litigation hereunder or in relation
         hereto, at the request, order or direction of any of the
         Certificateholders, pursuant to the provisions of this Trust Agreement,
         unless such Certificateholders shall have offered to the Trustee
         reasonable security or indemnity against the costs, expenses and
         liabilities which may be incurred therein or thereby;

                  (iv) the Trustee shall not be personally liable for any action
         taken, suffered or omitted by it in good faith and believed by it to be
         authorized or within the discretion or rights or powers conferred upon
         it by this Trust Agreement;

                  (v) the Trustee shall not be bound to make any investigation
         into the facts of matters stated in any resolution, certificate,
         statement, instrument, opinion, report, notice, facsimile transmission,
         request, consent, order, appraisal, approval, bond or other paper or
         document believed by it to be genuine, unless requested in writing to
         do so by Holders of the Required Percentage--Direction of Trustee of
         the aggregate Voting Rights of the affected Series (or Class or Classes
         within any such Series), as specified by the applicable Supplement;
         provided, however, that if the payment within a reasonable time to the
         Trustee of the costs, expenses or liabilities likely to be incurred by
         it in the making of such investigation is, in the opinion of the
         Trustee, not reasonably assured to the Trustee by the security afforded
         to it by the terms of this Trust Agreement, the Trustee may require
         reasonable indemnity against such expense or liability as a condition
         to taking any such action;

                  (vi) the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents or attorneys or a



<PAGE>


                                       66

         custodian and shall not be liable for any misconduct or negligence of
         any such agents or attorneys selected with due care by it; and

                  (vii) the Trustee shall not be personally liable for any loss
         resulting from the investment of funds held in any Certificate Account
         or Reserve Account in accordance with Section 3.05.

                  (b) All rights of action under this Trust Agreement or under
any of the Certificates, enforceable by the Trustee, may be enforced by it
without the possession of any of the Certificates of any Series (or Class within
such Series), or the production thereof at the trial or other Proceeding
relating thereto, and any such Proceeding instituted by the Trustee shall be
brought in its name for the benefit of all the Holders of such Certificates,
subject to the provisions of this Trust Agreement.

                  Section 7.04. Trustee Not Liable for Recitals in Certificates
or Underlying Securities. The Trustee assumes no responsibility for the
correctness of the recitals contained herein and in the Certificates or in any
document issued in connection with the sale of the Certificates (other than the
signature and authentication on the Certificates). Except as set forth in
Section 7.10, the Trustee makes no representations or warranties as to the
validity or sufficiency of this Trust Agreement or of the Certificates of any
Series (other than the signature and authentication on the Certificates) or of
any Underlying Security or related document. The Trustee shall not be
accountable for the use or application by the Depositor, of any of the
Certificates or of the proceeds of such Certificates.

                  Section 7.05. Trustee May Own Certificates. The Trustee in its
individual capacity or any other capacity may become the owner or pledgee of
Certificates with the same rights it would have if it were not Trustee;
provided, however, that in determining whether the required percentage of
aggregate Voting Rights shall have consented to any action hereunder requiring
the consent of the Certificateholders, any interest beneficially held by the
Trustee in its individual capacity shall be excluded.

                  Section 7.06. Trustee's Fees and Expenses. (a) The applicable
Supplement shall specify the amount and circumstances of the Trustee's
compensation and the source thereof.

                  (b) If the Prepaid Ordinary Expenses set forth in the
Supplement is greater than zero, the Trustee acknowledges that the Depositor has
paid to the Trustee an amount equal to the Prepaid Ordinary Expenses specified
therein, and the Trustee agrees that the payment of such amount shall constitute
full and final satisfaction of and payment for all such expenses.




<PAGE>


                                       67

                  (c) If the Prepaid Ordinary Expenses set forth in the
Supplement is zero, the Supplement may indicate that Ordinary Expenses will be
paid for by the Trust, in which case the Trustee shall be paid on a periodic
basis by the Trust at the rate or amount and on the terms provided for in the
Supplement. In such cases, the Trustee agrees that its right to receive such
payments from the Trust shall constitute full and final satisfaction of and
payment for all Ordinary Expenses and that the Trustee shall have no claim on
payment of Ordinary Expenses from any other source, including the Depositor.

                  (d) If the Prepaid Ordinary Expenses set forth in the
Supplement is zero, the Supplement may provide that the Depositor shall pay to
the Trustee from time to time a fee for its services and expenses as Trustee as
set forth in the Supplement payable at the times set forth therein. In such
cases, the Trustee agrees that its right to receive such payments from the
Depositor shall constitute full and final satisfaction of and payment for all
Ordinary Expenses and that the Trustee shall have no claim for payment of
Ordinary Expenses from the Trust. The Trustee further agrees that,
notwithstanding any failure by the Depositor to make such periodic payments of
the Ordinary Expenses, the Trustee shall continue to perform its obligations
under this Trust Agreement. The Depositor's obligations to pay Ordinary Expenses
under this Trust Agreement shall be extinguished and of no further effect upon
the payment of Ordinary Expenses due and owing on the termination of the Trust
pursuant to Section 10.01 hereof.

                  (e) Subject to paragraph (f) of this Section 7.06, all
Extraordinary Trust Expenses, to the extent not paid by a third party are, and
shall be, obligations of the Trust and when due and payable shall be satisfied
solely by the Trust.

                  (f) The Trustee shall not take any action, including appearing
in, instituting or conducting any action or suit hereunder or in relation hereto
which is not indemnifiable under Section 7.11 hereof which, in the Trustee's
opinion, would or might cause it to incur costs, expenses or liabilities that
are Extraordinary Trust Expenses unless (i) the Trustee is satisfied that it
will have adequate security or indemnity in respect of such costs, expenses and
liabilities, (ii) the Trustee has been instructed to do so by Certificateholders
representing not less than 100% of the aggregate principal amount of
Certificates then outstanding and (iii) such Certificateholders have agreed that
such costs, expenses or liabilities shall be paid by the Trustee from the Trust.

                  Section 7.07. Eligibility Requirements for Trustee. (a) The
Trustee hereunder shall at all times be a corporation or an association which is
not an Affiliate of the Depositor (but may have normal banking relationships
with the Depositor and its Affiliates) organized and doing business under the
laws of any State or the United States, authorized under such laws to exercise
corporate trust powers which shall be eligible to act as a trustee under TIA
Section 310(a), having a combined capital and surplus of at least $50,000,000,

<PAGE>


                                       68

S&P of BBB- or higher. If such corporation or association publishes reports of
conditions at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section 7.07 the combined capital and surplus of such corporation or association
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of conditions so published. In the event that at any time such
Trustee shall cease to be eligible in accordance with the provisions of this
Section 7.07, such Trustee shall resign immediately in the manner and with the
effect specified in Section 7.08.

                  (b) In determining whether the Trustee has a conflicting
interest under TIA Section 310(b) with respect to any Class of Certificates and
this Section 7.07, each other Class of Certificate will be treated as having
been issued under an indenture other than this Trust Agreement.

                  Section 7.08. Resignation or Removal of the Trustee;
Appointment of Successor Trustee. (a) The Trustee may at any time resign as
Trustee hereunder by written notice of its election so to do, delivered to the
Depositor, and such resignation shall take effect upon the appointment of a
successor Trustee and its acceptance of such appointment as hereinafter
provided; provided, however, that in the event of such resignation, the Trustee
shall (i) assist the Depositor in finding a successor Trustee acceptable to the
Depositor and (ii) negotiate in good faith concerning any prepaid but unaccrued
fees.

                  (b) The Depositor or Holders of the Required
Percentage--Removal of Trustee of Certificates may at any time remove the
Trustee as Trustee hereunder by written notice delivered to the Trustee in the
manner provided in Section 11.04 hereof, and such removal shall take effect upon
the appointment of the successor Trustee and its acceptance of such appointment
as provided in paragraph (e) of this Section 7.08; provided, however, that in
the event of such removal, the Depositor shall negotiate in good faith with the
Trustee in order to agree regarding payment of the termination costs of the
Trustee resulting from such removal.

                  (c) Upon the designation and acceptance thereof of a successor
Trustee, following either resignation or removal of the Trustee, the Trustee
shall deliver to the successor Trustee all records relating to the Certificates
in the form and manner then maintained by the Trustee, which shall include a
hard copy thereof upon written request of the successor Trustee.

                  (d) If at any time the Trustee shall become incapable of
acting or shall be adjudged a bankrupt or insolvent, or a receiver of the
Trustee or of its property shall be appointed, or any public officer shall take
charge or control of the Trustee or of its property of affairs for the purpose
of rehabilitation, conservation or liquidation, the Depositor shall petition any
court of competent jurisdiction for the removal of the Trustee and the



<PAGE>


                                       69

appointment of a successor Trustee. In the event the Trustee resigns or is
removed, the Trustee shall reimburse the Depositor for any fees or charges
previously paid to the Trustee in respect of duties not yet performed under this
Trust Agreement which remain to be performed by a successor Trustee.

                  (e) In case at any time the Trustee acting hereunder notifies
the Depositor that it elects to resign or the Depositor or Holders of the
Required Percentage--Removal of Trustee of Certificates notifies or notify the
Trustee that it or they elects or elect to remove the Trustee as Trustee, the
Depositor shall, within sixty (60) days after the delivery of the notice of
resignation or removal, appoint a successor Trustee, which shall satisfy the
requirements for a trustee under Section 7.07. If no successor Trustee has been
appointed within sixty (60) days after the Trustee has given written notice of
its election to resign or the Depositor or Holders of the Required
Percentage--Removal of Trustee of Certificates have given written notice to the
Trustee of its or their election to remove the Trustee, as the case may be, the
Trustee may petition any court of competent jurisdiction for the appointment of
a successor Trustee. Every successor Trustee shall execute and deliver to its
predecessor and to the Depositor an instrument in writing accepting its
appointment hereunder, and thereupon such successor Trustee, without any further
act or deed, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor and for all purposes shall be the Trustee under
this Trust Agreement, and such predecessor, upon payment of all sums due it and
on the written request of the Depositor, shall execute and deliver an instrument
transferring to such successor all rights, obligations and powers of such
predecessor hereunder, and shall duly assign, transfer and deliver all right,
title and interest in the Deposited Assets and parts thereof to such successor.
Any successor Trustee shall promptly give notice of its appointment to the
Certificateholders of Certificates for which it is successor Trustee in the
manner provided in Section 11.04 hereof.

                  (f) Any corporation into or with which the Trustee may be
merged, consolidated or converted shall be the successor of such Trustee without
the execution or filing of any document or any further act.

                  Section 7.09. Appointment of Office or Agency. As specified in
a Supplement, the Trustee shall appoint an office or agency in The City of New
York where the Certificates may be surrendered for registration of transfer or
exchange, and presented for the final distribution with respect thereto, and
where notices and demands to or upon the Trustee in respect of the Certificates
of the related Series and this Trust Agreement may be served.

                  Section 7.10. Representations and Warranties of Trustee. The
Trustee represents and warrants that:




<PAGE>


                                       70

                  (i) the Trustee is duly organized, validly existing and in
         good standing under the laws of its jurisdiction of incorporation or
         association;

                  (ii) neither the execution nor the delivery by the Trustee of
         this Trust Agreement, nor the consummation by it of the transactions
         contemplated hereby nor compliance by it with any of the terms or
         provisions hereof will contravene any Federal or New York law,
         governmental rule or regulation governing the banking or trust powers
         of the Trustee or any judgment or order binding on it, or violate its
         charter documents or by-laws or constitute a default under (or an event
         which, without notice or lapse of time or both, would constitute a
         default) under, or result in the breach or acceleration of any material
         contract, indenture, mortgage, agreement or instrument to which it is a
         party or by which any of its properties may be bound;

                  (iii) the Trustee has full power, authority and right to
         execute, deliver and perform its duties and obligations as set forth
         herein and in each Supplement to which it is a party and has taken all
         necessary action to authorize the execution, delivery and performance
         by it of this Trust Agreement;

                  (iv) this Trust Agreement has been duly executed and delivered
         by the Trustee and constitutes, subject to due execution by the
         Depositor, the legal, valid and binding obligation of the Trustee,
         enforceable in accordance with its terms, except as enforcement may be
         limited by the applicable bankruptcy, insolvency, reorganization,
         moratorium or similar laws affecting the rights of creditors generally
         and general principles of equity (regardless of whether such
         enforceability is considered in a proceeding in equity or at law);

                  (v) the Trustee is not in violation, and the execution and
         delivery of the Trust Agreement by the Trustee and its performance and
         compliance with the terms thereof will not constitute a violation, of
         any order or decree of any court or any order or regulation of any
         federal, state, municipal or governmental agency having jurisdiction
         over the Trustee or its properties, which violation would reasonably be
         expected to have a material adverse effect on the condition (financial
         or otherwise) or operations of the Trustee or its properties or on the
         performance of its duties hereunder;

                  (vi) there are no actions or proceedings against, or
         investigations of, the Trustee pending, or, to the knowledge of the
         Trustee, threatened, before any court, administrative agency or other
         tribunal (A) that could reasonably be expected to prohibit its entering
         into the Trust Agreement, (B) seeking to prevent the issuance of the
         Certificates contemplated by the Trust Agreement or (C) that could
         reasonably affect the performance by the Trustee of its obligations
         under, or the validity or enforceability against the Trustee of, the
         Trust Agreement; and



<PAGE>


                                       71


                  (vii) no consent, approval, authorization or order of any
         court, governmental agency or body is required for the execution,
         delivery and performance by the Trustee of, or compliance by the
         Trustee with, the Trust Agreement, or for the consummation of the
         transactions contemplated by the Trust Agreement, except for such
         consents, approvals, authorizations and orders, if any, that have been
         obtained prior to the Closing Date.

The representations and warranties of the Trustee set forth in this Section 7.10
shall survive the receipt of Underlying Securities by the Trustee and shall
survive the delivery of the Trust Agreement by the Trustee to the Depositor.

                  Section 7.11. Indemnification of Trustee by the Depositor;
Contribution. (a) The Depositor agrees, to the extent the Trustee is not
reimbursed pursuant to Section 7.06 hereof, to indemnify the Trustee against,
and hold it harmless from, any loss, expense or liability incurred in connection
with any Proceeding relating to this Trust Agreement or the Certificates or the
performance of any of the Trustee's duties hereunder, other than any loss,
liability or expense incurred by reason of wilful misfeasance, bad faith or
negligence in the performance of the Trustee's duties hereunder or by reason of
reckless disregard of the Trustee's obligations and duties hereunder.

                  (b) If the indemnification provided for in paragraph (a) of
this Section 7.11 is invalid or unenforceable in accordance with its terms, then
the Depositor shall contribute to the amount paid or payable by the Trustee as a
result of such liability in such proportion as is appropriate to reflect the
relative benefits received by the Depositor on one hand and the Trustee as
Trustee on the other hand. For this purpose (i) the benefits received by the
Depositor shall be the aggregate amount received by it upon the sale of such
Certificates, less the costs and expenses of such sale, including the cost of
acquisition of the Underlying Securities or parts thereof evidenced thereby, and
(ii) the benefits received by the Trustee, as Trustee shall be the aggregate
amount of fees received by it as Trustee, less costs and expenses incurred by it
as Trustee in relation to such Certificates. If, however, the allocation
provided by the immediately preceding two sentences is not permitted by
applicable law, then the Depositor shall contribute to such amount paid or
payable by the Trustee in such proportion as is appropriate to reflect not only
such relative benefits but also the relative fault of the Depositor on the one
hand and the Trustee on the other in connection with the actions or omissions
which resulted in such liability, as well as any other relevant equitable
considerations.

                  (c) In case any claim shall be made or action brought against
the Trustee for any reason for which indemnity may be sought against the
Depositor as provided above, the Trustee may promptly notify the Depositor in
writing setting forth the particulars of such claim or action and the Depositor
may assume the defense thereof. In the event that the Depositor assumes the
defense, the Trustee shall have the right to retain separate counsel in



<PAGE>


                                       72

any such action but shall bear the fees and expenses of such counsel unless (i)
the Depositor shall have specifically authorized the retaining of such counsel
or (ii) the parties to such suit include the Trustee and the Depositor, and the
Trustee has been advised in writing by such counsel that one or more legal
defenses may be available to it which may not be available to the Depositor, in
which case the Depositor shall not be entitled to assume the defense of such
suit notwithstanding its obligation to bear the reasonable fees and expenses of
such counsel.

                  (d) The term "Liability", as used in this Section 7.11, shall
include any losses, claims, damages, expenses (including without limitation the
Trustee's reasonable costs, expenses and attorneys' fees and expenses) in
defending itself against any losses, claims or investigations of any nature
whatsoever.

                  (e) The obligations of the Depositor under this Section 7.11
shall be in addition to any liability which the Depositor may otherwise have and
shall extend, upon the same terms and conditions, to each officer and director
of the Trustee, and to each person, if any, who controls the Trustee within the
meaning of the Exchange Act.

                  (f) Notwithstanding anything to the contrary contained in this
Section 7.11, the Depositor shall not be liable for settlement of any such claim
by the Trustee entered into without the prior written consent of the Depositor,
which consent shall not be unreasonably withheld.

                  (g) The indemnity provided in this Section 7.11 shall survive
the termination or discharge of this Trust Agreement.

                  Section 7.12. No Liability of the Trustee with Respect to the
Underlying Securities; Certificateholders to Proceed Directly Against the
Underlying Securities Issuer(s). (a) The sole obligor with respect to any
Underlying Security is the Underlying Securities Issuer(s). The Trustee shall
not have any obligation on or with respect to the Underlying Securities; and its
obligations with respect to Certificates shall be solely as set forth in this
Trust Agreement.

                  (b) The Trustee is not authorized to proceed against the
Underlying Securities Issuer in the event of a default or to assert the rights
and privileges of Certificateholders of Certificates and has no right or duty in
respect thereof except as expressly provided herein.

                  Section 7.13. The Depositor to Furnish Trustee with Names and
Addresses of Certificateholders. The Depositor will furnish to the Trustee
within 15 days after each Record Date with respect to any Distribution Date, and
at such other times as the Trustee may request in writing, within 30 days after
receipt by the Depositor of any such request, a list, in such form as the
Trustee may reasonably require, of all information in the possession



<PAGE>


                                       73

or control of the Depositor as to the names and addresses of the
Certificateholders, in each case as of a date not more than 15 days prior to the
time such list is furnished; provided, however, that so long as the Trustee is
the sole Registrar, no such list need be furnished.

                  Section 7.14. Preservation of Information. The Trustee shall
preserve, in as current a form as is reasonably practicable, the names and
addresses of Certificateholders contained in the most recent list furnished to
the Trustee as provided in Section 7.14, and the names and addresses of
Certificateholders received by the Trustee in its capacity as Registrar, if so
acting. The Trustee may destroy any list furnished to it as provided in Section
7.14, upon receipt of a new list so furnished.

                  Section 7.15. Reports by Trustee. If required, within 60 days
after May 15 of each year, commencing with the year 1998, the Trustee shall
transmit to the Certificateholders, as provided in TIA Section 313(c), a brief
report dated as of such May 15, if required by TIA Section 313(a).

                  Section 7.16. Trustee's Application for Instructions from the
Depositor. Any application by the Trustee for written instructions from the
Depositor may, at the option of the Trustee, set forth in writing any action
proposed to be taken or omitted by the Trustee under this Trust Agreement and
the date on and/or after which such action shall be taken or such omission shall
be effective, if, but only if, the obligations of the Trustee with respect to
such proposed action or omission, in the view of the Trustee, are not set forth
reasonably clearly in these Standard Terms and the related Supplement. The
Trustee shall not be liable for any action taken by, or omission of, the Trustee
in accordance with a proposal included in such application on or after the date
specified in such application (which date shall not be less than ten (10)
Business Days after the date a Responsible Officer of the Depositor actually
receives such application, unless any such Responsible Officer shall have
consented in writing to any earlier date) unless, prior to taking any such
action (or the effective date in the case of an omission), the Trustee shall
have received written instructions in response to such application specifying
the action to be taken or omitted; provided, however, that this provision shall
not protect the Trustee from liability for any action or omission constituting
willful misconduct, bad faith or negligence.

Agreement. The Market Agent, including any successor appointed pursuant hereto,
shall be a member of the National Association of Securities Dealers, Inc., have
capitalization of at least $25,000,000, and be authorized by law to perform all
the duties imposed upon it by this Trust Agreement and the Market Agent
Agreement. The Market Agent may be removed at any time by the Trustee, acting at
the written direction of the Depositor; provided, however, that such removal
shall not take effect until the appointment of a successor Market Agent. The
Market Agent may resign upon 30 days' written notice delivered to the Trustee.
The Depositor shall use its best efforts to appoint a successor Market Agent
that is a qualified institution, effective as of the effectiveness of any such
resignation or removal.


                                   ARTICLE IX

                             SECURITIES INTERMEDIARY

                  Section 9.01. Resignation or Removal of the Securities
Intermediary; Appointment of Successor Securities Intermediary. (a) The
Securities Intermediary may at any time resign as Securities Intermediary
hereunder by written notice of its election so to do, delivered to the Trustee
and the Depositor, and such resignation shall take effect upon the appointment
of a successor Securities Intermediary and its acceptance of such appointment as
hereinafter provided; provided, however, that in the event of such resignation,
the Securities Intermediary shall (i) assist the Trustee and the Depositor in
finding a successor Securities Intermediary acceptable to the Trustee and the
Depositor and (ii) negotiate in good faith concerning any prepaid but unaccrued
fees.

                  (b) The Trustee, the Depositor or the Holders of the Required
Percentage--Removal of Securities Intermediary of Certificates may at any time
remove the Securities Intermediary as Securities Intermediary hereunder by
written notice delivered to the Securities Intermediary in the manner provided
in Section 11.04 hereof, and such removal shall take effect upon the appointment
of the successor Securities Intermediary and its acceptance of such appointment
as provided in paragraph (e) of this Section 9.01; provided, however, that in
the event of such removal, the Depositor shall negotiate in good faith with the
Securities Intermediary in order to agree regarding payment of the termination
costs of the Securities Intermediary resulting from such removal.

                  (c) Upon the designation and acceptance thereof of a successor
Securities Intermediary, following either resignation or removal of the
Securities Intermediary, the Securities Intermediary shall deliver to the
successor Securities Intermediary all records relating to the Certificates in
the form and manner then maintained by the Securities Intermediary, which shall
include a hard copy thereof upon written request of the successor Securities
Intermediary.

                                       75

                  (d) If at any time the Securities Intermediary shall become
incapable of acting or shall be adjudged a bankrupt or insolvent, or a receiver
of the Securities Intermediary or of its property shall be appointed, or any
public officer shall take charge or control of the Securities Intermediary or of
its property of affairs for the purpose of rehabilitation, conservation or
liquidation, the Depositor shall petition any court of competent jurisdiction
for the removal of the Securities Intermediary and the appointment of a
successor Securities Intermediary. In the event the Securities Intermediary
resigns or is removed, the Securities Intermediary shall reimburse the Depositor
for any fees or charges previously paid to the Securities Intermediary in
respect of duties not yet performed under this Trust Agreement which remain to
be performed by a successor Securities Intermediary.

                  (e) In case at any time the Securities Intermediary acting
hereunder notifies the Trustee or the Depositor that it elects to resign or the
Trustee, the Depositor or Holders of the Required Percentage--Removal of
Securities Intermediary of Certificates notifies or notify the Securities
Intermediary that it or they elects or elect to remove the Securities
Intermediary as Securities Intermediary, the Depositor shall, within sixty (60)
days after the delivery of the notice of resignation or removal, appoint a
successor Securities Intermediary, which shall satisfy the requirements set
forth in Section 2.06. If no successor Securities Intermediary has been
appointed within sixty (60) days after the Securities Intermediary has given
written notice of its election to resign or the Trustee, the Depositor or
Holders of the Required Percentage--Removal of Securities Intermediary of
Certificates have given written notice to the Securities Intermediary of its or
their election to remove the Securities Intermediary, as the case may be, the
Securities Intermediary may petition any court of competent jurisdiction for the
appointment of a successor Securities Intermediary. Every successor Securities
Intermediary shall execute and deliver to its predecessor, to the Trustee and to
the Depositor an instrument in writing accepting its appointment hereunder, and
thereupon such successor Securities Intermediary, without any further act or
deed, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor and for all purposes shall be the Securities
Intermediary under this Trust Agreement, and such predecessor, upon payment of
all sums due it and on the written request of the Trustee and the Depositor,
shall execute and deliver an instrument transferring to such successor all
rights, obligations and powers of such predecessor hereunder, and shall duly
assign, transfer and deliver all right, title and interest in the Deposited
Assets and parts thereof to such successor. Any successor Securities
Intermediary shall promptly give notice of its appointment to the
Certificateholders of Certificates for which it is successor Securities
Intermediary in the manner provided in Section 11.04 hereof.

                  (f) Any corporation into or with which the Securities
Intermediary may be merged, consolidated or converted shall be the successor of
such Securities Intermediary without the execution or filing of any document or
any further act.

                  Section 10.01. Termination upon Liquidation of All Underlying
Securities. (a) The respective obligations and responsibilities under this Trust
Agreement of the Depositor and the Trustee (other than the obligations of the
Trustee to make distributions to Holders of the Certificates of any given Series
as hereafter set forth and to provide information reports and information tax
reporting) shall terminate upon the distribution to such Holders of all amounts
held in all the Accounts for such Series and required to be paid to such Holders

purchase thereof by the applicable Underlying Securities Issuer) (or any Advance
with respect thereto) of the last Underlying Security remaining in the Trust for
such Series or the disposition of all property acquired upon liquidation of any
such Underlying Security; provided, however, that in no event shall any trust
created hereby continue beyond the earlier of (1) any date set forth in Section

the expiration of 21 years from the death of the last survivor of the

                  (b) The Depositor shall provide the Trustee with written
notice of any of the events set forth in paragraph (a) of this Section 10.01.

                  (c) Upon presentation and surrender of the Certificates by the
Certificateholders on the Final Scheduled Distribution Date, or the Distribution
Date coinciding with or next following the earlier to occur of the occurrences
specified in paragraph (a) of this Section 10.01, with respect to the applicable
Series of Certificates, the Trustee shall distribute to each Holder presenting

Distribution Date in accordance with Section 4.01 in respect of the Certificates
so presented and surrendered, or (ii) as specified in the applicable Supplement,
if in connection with the Trustee's sale of all the remaining Underlying
Securities. Any funds not distributed on such Distribution Date shall be set
aside and held in trust for the benefit of Certificateholders not presenting and
surrendering their Certificates in the aforesaid manner, and shall be disposed
of in accordance with this Section 10.01 and Section 4.01 hereof. Immediately
following the deposit of funds in trust hereunder, the Trust for such Series
shall terminate. Subject to applicable escheat laws, the Trustee shall pay to
the Depositor any cash that remains unclaimed, together with interest, if any,
thereon, held by the Trustee on the date two years after such termination.

                  (i) to cure any ambiguity;

                  (ii) to correct or supplement any provision herein that may be
         inconsistent with any other provision herein or in the Supplement;

                  (iii) to change the Trustee or the Securities Intermediary for
         a Series subsequent to the Closing Date for such Series;

                  (iv) to provide for administration of separate Trusts by more
         than one trustee;

                  (v) to provide for a successor Trustee or successor Securities

                  (vii) to add or supplement any Credit Support for the benefit
         of any Certificateholders (provided, however, that if any such addition
         affects any Series or Class of Certificateholders differently than any
         other Series or Class of Certificateholders, then such addition will
         not, as evidenced by an Opinion of Counsel, have a material adverse
         effect on the interests of any affected Series or Class of
         Certificateholders);

                  (viii) to add to the covenants, restrictions or obligations of

                                       78

Any amendment made pursuant to this paragraph (a) is subject to the condition
that such amendment shall satisfy the Rating Agency Condition with respect to
such amendment and shall not cause any Trust created hereunder to fail to
qualify as a fixed investment trust (or "grantor trust") for federal income tax
purposes.

                  (b) Without limiting the generality of the foregoing, unless
otherwise specified in the applicable Supplement, with respect to any Series,
this Trust Agreement may also be modified or amended from time to time by the
Depositor, the Trustee and the Securities Intermediary with the consent of the
Holders of Certificates representing the Required Percentage--Amendment of the
aggregate Voting Rights of those Certificates that are adversely affected by
such modification or amendment for the purpose of adding any provision to or
changing in any manner or eliminating any of the provisions of this Trust
Agreement or of modifying in any manner the rights of the Holders of
Certificates; provided, however, that no such amendment shall (i) reduce in any
manner the amount of, or delay the timing of, payments received on Underlying
Securities which are required to be distributed on any Certificate without the
consent of the Holders of such Certificates, (ii) reduce the percentage of
aggregate Voting Rights required to take any action specified in this Trust

Securities Intermediary or any Affiliate of the Depositor, the Trustee or the
Securities Intermediary shall be entitled to Voting Rights with respect to
matters affecting such Certificates. Notwithstanding any other provision of this
Trust Agreement, this paragraph (b) shall not be amended without the unanimous
consent of the Holders of all such Certificates.

                  (c) Promptly after the execution of any such amendment or
modification, the Trustee shall furnish a copy of such amendment or modification
to each Certificateholder of the affected Series or Class and to the Rating
Agency. It shall not be necessary for the consent of Certificateholders under
this Section 11.01 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 by Certificateholders shall be subject to such reasonable
regulations as the Trustee may prescribe.

                  Section 11.02. Limitation on Rights of Certificateholders. (a)

this Trust Agreement or the Trust, nor entitle such Certificateholder's legal
representatives or heirs to claim an accounting or to take any action or
Proceeding in any court for a partition or winding up of

nor shall any Certificateholder be under any liability to any third person by
reason of any action taken by the parties to this Trust Agreement other than
pursuant to the provisions hereof.

                  (c) No Certificateholder of a given Series shall have any
right by virtue of any provision of this Trust Agreement to institute any

Agreement, unless:

                  (i) such Holder previously shall have given to the Trustee a
         written notice of breach of this Trust Agreement and of the continuance
         thereof;

                  (ii) the Holders of Certificates of such Series evidencing not
         less than the Required Percentage--Remedies of the aggregate Voting
         Rights of such Series shall have made written request upon the Trustee
         to institute such Proceeding in its own name as Trustee hereunder;

                  (iii) such Certificateholder or Certificateholders shall have
         offered to the Trustee such reasonable indemnity as it may require
         against the costs, expenses and liabilities to be incurred therein or
         thereby;

                  (iv) the Trustee, for 15 days after its receipt of such
         notice, request and offer of indemnity, shall have neglected or refused
         to institute any such Proceeding; and

         been given to the Trustee during such 15-day period by
         Certificateholders evidencing not less than the Required
         Percentage--Remedies of the aggregate Voting Rights of such Series.

It is understood and agreed that the Trustee shall not be obligated to make any
investigation of matters arising under this Trust Agreement or to institute,
conduct or defend any Proceeding hereunder or in relation hereto at the request,
order or direction of any Certificateholders unless such Certificateholders have
offered to the Trustee the reasonable indemnity referred to above. It is further
understood and agreed, and expressly covenanted by each Certificateholder of
each Series with every other Certificateholder of such Series and the Trustee,
that no one or more Holders of Certificates of such Series shall have any right

affect, disturb or prejudice the rights of the Holders of any other of the
Certificates of such Series, or to obtain or seek to obtain priority over or
preference to any other such Holder, or to enforce any right under this Trust
Agreement, except in the manner herein provided and for the equal, ratable and

                            (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
Deposited Assets (to the extent of its rights therein) for interest
distributions hereunder. Both the Underlying Securities and Call Holders that
exercise their Call Rights may be sources of principal distributions on the
Certificates. The rights of the Certificate-holders under the Trust Agreement
and this Certificate are limited by the terms, provisions and conditions of the
Trust Agreement and the Warrant Agreement with respect to the exercise of Call
Rights by the holders of Call Rights. The Certificateholders, by their
acceptance of the Certificates, covenant and agree to tender any and all
Certificates to the Warrant Agent upon the holder's exercise of Call Rights and
deposit of the Call Price with the Escrow Agent for such Certificates in
accordance with the applicable procedures in the Warrant Agreement.

                  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 Certificates evidencing greater
than 66 2/3% of the aggregate Voting Rights of the Certificates subject to
certain provisions set forth in the Trust Agreement. 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.

                  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 signed by, the Holder hereof, 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 United States Trust Company of New York.

                  No service charge will be made for any registration of
transfer or exchange, but the Trustee may require payment 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, the Trustee and the Securities Intermediary and
any agent of the Depositor, the Trustee or the Securities Intermediary may treat
the Person in whose name this Certificate is registered as the owner hereof for
all purposes, and neither the Depositor, the Trustee, or the Securities
Intermediary 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
United States federal income tax purposes under Treasury Regulation Section
301.7701-4, and the Certificateholder, by its acceptance of this Certificate,
agrees to treat the Certificates, the distributions from the Trust and its
beneficial interest in the Trust consistently with such characterization.

                  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 Deposited Assets and the issuance of the Certificates and the Call
Rights, 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 Rights or otherwise incur, assume or guarantee any indebtedness for
money borrowed.

                  The Trust and the obligations of the Depositor, the Trustee
and the Securities Intermediary created by the Trust Agreement with respect to
the Certificates shall terminate upon the earlier 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 in respect of the Certificates and (ii) November 15, 2028.

Income Security Act of 1974, as amended ("ERISA"), including an individual
retirement account or Keogh plan (each, a "Plan"), purchases Certificates,
certain aspects of such investment, including the operation of the Trust, might
be subject to the prohibited transaction provisions under ERISA and the Internal
Revenue Code of 1986, as amended (the "Code"), unless certain exemptions apply.
A Plan should consult its advisors concerning the ability of such Plan to
purchase Certificates under ERISA or the Code.

                  (a) On the Exercise Date, simultaneously with the transfer of
Trust Certificates to the Holder that were subject to the Holder's Warrants
(including any such Trust Certificates deposited as set forth in paragraph 1),
except where the Exercise Date is a deemed Exercise Date pursuant to Section

(the "Closing," the period of time between the initial deposit of the Escrow
Deposit and the Closing being referred to as the "Escrow Period") in accordance
with the terms of the Warrant Agreement (i) the Escrow Agent shall pay to the
Holder all interest, and interest earned on interest, on any cash in the Escrow
Deposit to the Closing Date in lawful money of the United States of America by

the order of a payee or payees designated by the Holder; provided, however, that
if the Escrow Agent receives a written objection from the Trust to such release
of such cash in the Escrow Deposit within seven (7) business days after the
Holder gives such written notice, then the Escrow Agent shall pay the cash
amount in the Escrow Deposit and any interest, and interest earned on interest,
on such amounts in accordance with joint written instructions from the Holder
and the Trust, or, in the absence of such joint written instructions, the
provisions of Section 6 hereof shall apply.


<PAGE>

                  4. Liability of Escrow Agent. The Escrow Agent shall not incur
any liability to any party for damages, losses or expenses for (a) any act or
failure to act made or omitted in good faith and without gross negligence or
willful misconduct or (b) any action taken or omitted in reliance upon any
instrument that the Escrow Agent shall in good faith believe to be genuine, nor
will the Escrow Agent be liable or responsible for forgeries, fraud,
impersonations, or determining the scope of any representative authority. In
addition, the Escrow Agent may consult with legal counsel in connection with the
Escrow Agent's duties under this Agreement and shall be fully protected in any
act taken, suffered, or permitted by it in good faith in accordance with the
advice of counsel. The Escrow Agent is not responsible for determining and
verifying the authority of any person acting or purporting to act on behalf of
any party to this Agreement.

                  5. Escrow. The Escrow Agent can incur reasonable expenses in
connection with its duties and incur legal fees and expenses in connection with
this Agreement with any firm, and such expenses shall be paid or reimbursed, as
the case may be, in accordance with Section 7 of this Agreement. In the event
that the conditions of this Agreement are not properly fulfilled, or if the
Escrow Agent renders any service not provided for in this Agreement, or if the
parties request a substantial modification of its terms, or if any controversy
arises, or if the Escrow Agent is made a party to, or intervenes in, any
litigation pertaining to this escrow or its subject matter, the Escrow Agent
shall be reasonably compensated for such extraordinary service and reimbursed
for all reasonable costs, attorneys' fees and expenses of any firm occasioned by
such default, delay, controversy or litigation and the Escrow Agent shall have
the right to retain all documents and/or other things of value at any time held
by Escrow Agent in this escrow until such compensation, fees, costs, and
expenses are paid.

                  6. Controversies. If any controversy arises relating to this
Agreement, or with any other party concerning the subject matter of this
Agreement, its terms or conditions, the Escrow Agent will not be required to
determine the controversy or to take any action regarding it. The Escrow Agent
may hold the Escrow Funds (as hereinafter defined) and may wait for settlement
of any such controversy by final appropriate legal proceedings or other means,
as, in the Escrow Agent's discretion, the Escrow Agent may deem appropriate
despite what may be set forth elsewhere in this Agreement. In such event, the
Escrow Agent will not be liable for damages as long as the Escrow Agent acts in
good faith and without gross negligence or willful misconduct. The Escrow Agent
is authorized to deposit with the clerk of any court the Escrow Funds held
hereunder. Upon initiating an interpleader or declaratory judgment or any other
action seeking to determine the rights of the parties hereunder and depositing
the Escrow Funds, the Escrow Agent shall be fully released and discharged of and
from all further obligations and liability imposed by the terms of this
Agreement, but not as to acts of the Escrow Agent prior thereto. As used herein,
the term "Escrow Funds" means the Escrow Deposit plus all interest, and interest
earned on interest, on the Escrow Deposit.

                  7. Indemnification of Escrow Agent. The Holder and its
successors and assigns agrees to indemnify and hold Escrow Agent harmless
against any and all losses, claims, damages, liabilities and expenses, including
reasonable costs of investigation and reasonable counsel fees and disbursements,
that may be imposed on the Escrow Agent or incurred by the Escrow Agent in good
faith and without gross negligence or willful misconduct in connection


<PAGE>

with the performance of the duties under this Agreement, including, but not
limited to, any litigation arising from this Agreement or involving its subject
matter.

                  8. Termination. Except for the provisions of Section 7, which
shall survive this Agreement, this Agreement shall terminate upon the day on
which all of the Escrow Funds are disbursed in full in accordance with this
Agreement.

delivered under this Agreement shall be valid if (i) hand-delivered, (ii) sent
