     containing such information as the Trustee may require to settle said
     transactions.  Except as provided in the following subparagraphs (ii),
     (iii) and (iv), the Depositor in each case shall ensure that each deposit
     of additional Securities pursuant to this Section shall be, as nearly as is
     practicable, equal to the original percentage relationship among the number
     of shares of each Security as is specified in the Prospectus for such Trust
     Fund, adjusted as hereinafter provided (the "Percentage Ratio").  The
     Percentage Ratio shall be adjusted, as directed by the Depositor, to
     reflect (x) the deposit of New Securities, (y) the sale of Securities
     pursuant to Sections 3.06, 3.08, 3.12, 5.02 or otherwise as provided
     hereunder, and (z) the occurrence of any stock dividend, stock splits,
     receipt of securities under Section 3.08, redemptions, or similar events.
     Any brokerage fees related to the purchase of Securities deposited in the
     Trust Fund after the Initial Date of Deposit shall be an expense of such
     Trust Fund.  The Depositor shall deliver the additional Securities which
     were not delivered concurrently with the deposit of additional Securities
     and which were represented by Contract Obligations within 10 calendar days
     after such deposit of additional Securities (the "Additional Securities
     Delivery Period").  If a contract to buy such Securities between the
     Depositor and seller is terminated by the seller thereof for any reason
     beyond the control of the Depositor or if for any other reason such
     Securities are not delivered to the Trust Fund by the end of the Additional
     Securities Delivery Period for such deposit, the Trustee shall immediately
     draw on the Letter of Credit, if any, in amounts sufficient to settle such
     contract, apply the monies in accordance with Section 2.01(d), and the
     Depositor shall forthwith take the remedial action specified in Section
     3.10.  If the Depositor does not take the action specified in Section 3.10
     within 10 calendar days of the end of the Additional Securities Delivery
     Period, the Trustee shall forthwith take the action specified in Section
     3.10.  When requested by the Trustee, the

                                      -8-
<PAGE>

     Depositor shall arrange for the execution of purchases in accordance with
     such instructions; the Depositor shall be entitled to compensation therefor
     in accordance with applicable law and regulations. The Trustee shall have
     no liability for any loss or depreciation resulting from any purchase made
     pursuant to the Depositor's instructions or made by the Depositor as
     broker.

            (ii) Additional Securities (or Contract Securities therefor) may, at
     the Depositor's discretion, be deposited or purchased in round lots.  If
     the amount of the deposit is insufficient to acquire round lots of each
     Security to be acquired, the additional Securities shall be deposited or
     purchased in the order of the Security in the Trust Fund most under-
     represented immediately before the deposit with respect to the Percentage
     Ratio.

            (iii) If at the time of a deposit of additional Securities,
     Securities of an issue deposited on the Initial Date of Deposit (or of an
     issue of Replacement Securities acquired to replace an issue deposited on
     the Initial Date of Deposit) are unavailable, cannot be purchased at
     reasonable prices or their purchase is prohibited or restricted by
     applicable law, regulation or policies, the Depositor may (x) deposit, or
     instruct the Trustee to purchase, in lieu thereof, another issue of
     Securities or Replacement Securities or (y) deposit cash or a letter of
     credit in an amount equal to the valuation of the issue of Securities whose
     acquisition is not feasible with instructions to acquire such Securities of
     such issue when they become available.

            (iv) Any contrary authorization in the preceding subparagraphs (i)
     through (iii) notwithstanding, deposits of additional Securities made after
     the 90-day period immediately following the Initial Date of Deposit (except
     for deposits made to replace failed Contract Securities ("Special
     Securities") if such deposits occur within 20 days from the date of a
     failure occurring within such initial 90-day period) shall maintain exactly
     the Percentage Ratio existing immediately prior to such deposit.

            (v) In connection with and at the time of any deposit of additional
     Securities pursuant to this Section 2.01(b), the Depositor shall exactly
     replicate Cash (as defined below) received or receivable by the Trust Fund
     as of the date of such deposit.  For purposes of this paragraph, "Cash"
     means, as to the Capital Account, cash or other property (other than
     Securities) on hand in the Capital Account or receivable and to be credited
     to the Capital Account as of the date of the deposit (other than amounts to
     be distributed solely to persons other than holders of Units created by the
     deposit) and, as to the Income Account, cash or other property (other than
     Securities) received by the Trust Fund as of the date of the deposit or
     receivable by the Trust Fund in respect of a record date for payment on a
     Security which has occurred or will occur before the Trust Fund will be the
     holder of record of a Security, reduced by (x) the amount of any cash or
     other property received or receivable on any Security allocable (in
     accordance with the Trustee's calculations of distributions from the Income
     Account pursuant to Section 3.05) to a distribution made or to be made in
     respect of a Record Date occurring prior to the deposit and (y) unpaid fees
     and expenses allocable to the period prior to the deposit.  Such
     replication will be made on the basis of a fraction, the numerator of which
     is the

                                      -9-
<PAGE>

     number of Units created by the deposit and the denominator of which is the
     number of Units which are outstanding immediately prior to the deposit.
     Cash represented by a foreign currency shall be replicated in such currency
     or, if the Trustee has entered into a contract for the conversion thereof,
     in U.S. dollars in an amount replicating the dollars to be received on such
     conversion.

     (2) If a Trust has elected to be treated as a "regulated investment
company" as defined in the Internal Revenue Code, the following section shall
apply:

            (i) From time to time following the Initial Date of Deposit for a
     Trust Fund, the Depositor is hereby authorized, in its discretion, to
     assign, convey to and deposit with the Trustee (x) additional Securities
     for such Trust Fund, duly endorsed in blank or accompanied by all necessary
     instruments of assignment and transfer in proper form, or (y) Contract
     Securities relating to such additional Securities, accompanied by cash
     and/or Letter(s) of Credit as specified in paragraph (c) of this Section
     2.01.  In lieu of additional Securities or Contract Securities, the
     Depositor may deposit with the Trustee cash (or a Letter of Credit) in an
     amount equal to the valuation made in accordance with Section 4.01 for the
     date of such deposit of the additional Securities not delivered or
     represented by Contract Securities and the Depositor or its designated
     agent shall, on behalf of each Trust Fund, enter into contracts to purchase
     such additional Securities and shall provide the Trustee such information
     as the Trustee may require in order to settle such transactions and take
     delivery of such additional Securities which the Trustee is hereby directed
     to do.  If the Trust Fund involved seeks to consist of securities included
     in a securities index, deposits of additional Securities shall consist of
     Securities included in the applicable index as determined by the Depositor
     or its designee.  Any brokerage fees related to the purchase of Securities
     deposited in the Trust Fund after the Initial Date of Deposit shall be an
     expense of such Trust Fund.  The Depositor shall deliver any additional
     Securities which were not delivered concurrently with the deposit of
     additional Securities and which were represented by Contract Obligations
     within 10 calendar days after such deposit of additional Securities (the
     "Additional Securities Delivery Period").  If a contract to buy such
     Securities between the Depositor and seller is terminated by the seller
     thereof for any reason beyond the control of the Depositor or if for any
     other reason such Securities are not delivered to a Trust Fund by the end
     of the Additional Securities Delivery Period for such deposit, the Trustee
     shall immediately draw on the Letter of Credit, if any, in amounts
     sufficient to settle such contract, apply the monies in accordance with
     Section 2.01(d), and the Depositor shall forthwith take the remedial action
     specified in Section 3.10.  If the Depositor does not take the action
     specified in Section 3.10 within 10 calendar days of the end of the
     Additional Securities Delivery Period, the Trustee shall forthwith take the
     action specified in Section 3.10.  If the Depositor has acted as broker in
     connection with any purchase of Securities made on behalf of a Trust Fund,
     which it is hereby authorized to do, it shall be entitled to reimbursement
     in accordance with applicable law and regulations.  The Trustee shall have
     no liability for any loss or depreciation resulting from any acquisition of
     Securities pursuant to this Section (other than to confirm the identity and
     amount of Securities delivered to it pursuant to contracts deposited or
     entered into by the Depositor) and shall have no responsibility for the
     composition of a Trust Fund's portfolio.

                                     -10-
<PAGE>

            (ii) Additional Securities (or Contract Securities therefor) may, at
     the Depositor's discretion, be deposited or purchased in round lots.  If
     the amount of the deposit is insufficient to acquire round lots of each
     Security to be acquired, the additional Securities shall be deposited or
     purchased in accordance with the instructions of the Depositor or its
     designee.

            (iii) If at the time of a deposit of additional Securities,
     Securities of an issue deposited on the Initial Date of Deposit (or of an
     issue of Replacement Securities acquired to replace an issue deposited on
     the Initial Date of Deposit) are unavailable, cannot be purchased at
     reasonable prices or their purchase is prohibited or restricted by
     applicable law, regulation or policies, the Depositor may (x) deposit, or
     purchase on behalf of each Trust or designate an agent to purchase on
     behalf of each Trust in respect of cash deposited therein for such purpose,
     in lieu thereof, another issue of Securities or Replacement Securities or
     (y) deposit cash or a letter of credit in an amount equal to the valuation
     of the issue of Securities whose acquisition is not feasible and enter into
     contracts, or designate an agent to enter into contracts, on behalf of a
     Trust Fund to acquire such Securities of such issue when they become
     available.

            (iv) In connection with and at the time of any deposit of additional
     Securities pursuant to this Section 2.01(b), the Depositor shall exactly
     replicate Cash (as defined below) received or receivable by the Trust Fund
     as of the date of such deposit.  For purposes of this paragraph, "Cash"
     means, as to the Capital Account, cash or other property (other than
     Securities) on hand in the Capital Account or receivable and to be credited
     to the Capital Account as of the date of the deposit (other than amounts to
     be distributed solely to persons other than holders of Units created by the
     deposit) and, as to the Income Account, cash or other property (other than
     Securities) received by the Trust Fund in respect of a record date for a
     payment on a Security which has occurred or will occur before a Trust Fund
     will be the holder of record of a Security, reduced by (x) the amount of
     any cash or other property received or receivable on any Security allocable
     (in accordance with the Trustee's calculations of distributions from the
     Income Account pursuant to Section 3.05) to a distribution made or to be
     made in respect of a Record Date occurring prior to the deposit and (y)
     unpaid fees and expenses allocable to the period prior to the deposit.
     Such replication will be made on the basis of a fraction, the numerator of
     which is the number of Units created by the deposit and the denominator of
     which is the number of Units which are outstanding immediately prior to the
     deposit.  Cash represented by a foreign currency shall be replicated in
     such currency or, if the Trustee has entered into a contract for the
     conversion thereof, in U.S. dollars in an amount replicating the dollars to
     be received on such conversion.

     (c) Except as otherwise provided for in Section 8.01(e), in connection
with the deposits described in Section 2.01(a) and (b), the Depositor has, in
the case of Section 2.01(a) deposits, and, prior to the Trustee accepting a
Section 2.01(b) deposit, will, deposit cash and/or Letter(s) of Credit in an
amount sufficient to purchase the Contract Obligations (the "Purchase Amount")
relating to Securities which are not actually delivered to the Trustee at the
time of such deposit, the terms of which unconditionally allow the Trustee to
draw on the full amount of the available Letter of Credit.  The Trustee may
allow the Depositor to substitute any Letter(s) of Credit

                                     -11-
<PAGE>

deposited with the Trustee in connection with the deposits described in Section
2.01(a) and (b) with cash in an amount sufficient to satisfy the obligations to
which the Letter(s) of Credit relates. Any substituted Letter(s) of Credit shall
be released by the Trustee. The Trustee may deposit such cash or cash drawn on
the Letter of Credit in a non-interest bearing account for the Trust Fund. If
any Contract Obligation requires settlement in a foreign currency, in connection
with the deposit of such Contract Obligation the Depositor will deposit with the
Trustee either an amount of such currency sufficient to settle the contract or a
foreign exchange contract in such amount which settles concurrently with the
settlement of the Contract Obligation and cash or a Letter of Credit in U.S.
dollars sufficient to perform such foreign exchange contract.

     (d) In the event that the purchase of Securities or Contract Securities
pursuant to any contract shall not be consummated in accordance with said
contract or if the Securities represented by a Contract Obligation are not
delivered to the Trust Fund in accordance with Section 2.01(a) or 2.01(b) and
the monies, or, if applicable, the monies drawn on the Letter of Credit,
deposited by the Depositor are not utilized, and the Depositor does not, on or
before the third Business Day prior to the next following Distribution Date,
direct the Trustee to utilize monies deposited for the purchase of Replacement
Securities or Replacement Contract Securities, the Trustee shall credit to the
Capital Account referred to in Section 3.02 the monies, or, if applicable, the
monies drawn on an irrevocable letter of credit, deposited by the Depositor for
the purpose of such purchase.  Such funds shall be distributed pursuant to
Section 3.04 to Unitholders of record as of the Record Date next following the
failure of consummation of such purchase.  The Depositor shall cause to be
refunded to each Unitholder his pro rata portion of the sales charge levied on
the sale of Units to such Unitholder attributable to such Security or Contract
Security.

     (e) The Trustee is hereby irrevocably authorized to effect registration or
transfer of the Securities in fully registered form to the name of the Trustee
or to the name of its nominee.

     (f) With respect to Units created by the deposit of additional Securities,
annual fees payable hereunder shall be calculated, and estimated expenses (other
than organizational expenses borne by the Trust Fund pursuant to Section 10.02)
shall be estimated, ratably on the basis of the period during which such Units
have been in existence.  The Depositor shall from time to time provide the
Trustee estimates of the total number of additional Securities to be deposited
and total number of Units to be created, on which the Trustee is authorized
conclusively to rely for purposes of estimating income, expenses and the accrual
thereof.  In the event the Trustee is informed by the Depositor of a revision in
its estimates and upon the conclusion of the deposit of additional Securities,
the Trustee shall base calculations made thereafter on such revised estimates or
actual expenses, respectively, but any such revision shall not affect
calculations made prior thereto and no adjustment shall be made in respect
thereof.

     Section 2.02.  Acceptance of Trust.  The Trustee hereby accepts the trusts
herein created, and the Trustee declares that it holds and will hold the Trust
Fund as Trustee, in trust upon the trusts herein set forth, for the use and
benefit of the present and future Unitholders and subject to the terms and
conditions of the Trust Agreement and this Agreement.

                                     -12-

     Section 2.03.  Issuance of Units.  (a) The Trustee hereby acknowledges
receipt of the deposit of the Securities listed in Schedule A to the Trust
Agreement and referred to in Section 2.01 hereof and, simultaneously with the
receipt of said deposit, has recorded on its books the ownership, by the
Depositor or such other person or persons as may be indicated by the Depositor,
of the aggregate number of Units specified in the Trust Agreement. The number of
Units may be increased through a split of the Units or decreased through a
reverse split thereof, as directed in writing by the Depositor, at any time when
the Depositor is the only beneficial holder of Units, which revised number of
Units shall be recorded by the Trustee on its books. The Trustee shall be
entitled to rely on the Depositor's direction as certification that no person
other than the Depositor has a beneficial interest in the Units and the Trustee
shall have no liability to any person for action taken pursuant to such
direction. The Trustee hereby agrees that on the date of any deposit of
additional Securities, it shall acknowledge that the additional Securities have
been deposited with it by recording on its books the ownership, by the Depositor
or such other person or persons as may be indicated by the Depositor, of the
aggregate number of Units to be issued in respect of such additional Securities
so deposited.

     (b) Units will be held in uncertificated form unless the Trust Fund
Prospectus provides otherwise.  If so provided in the Prospectus for a Trust
Fund, under the terms and conditions of the Trust Agreement and this Agreement
and at such times as are permitted by the Trustee, Units may also be held in
certificated form.  Unitholders may elect to have their Units held in
certificated form by making a written request to the Trustee requesting Units be
held in certificated form.  The Trustee is entitled to specify the minimum
denomination of any Certificate issued.  The Trustee shall, at the request of
the holder of any Units held in uncertificated form, issue a new Certificate to
evidence such Units and at such time make an appropriate notation in the
registration books of the Trustee.  The rights set forth in this Agreement of
any holder of Units held in certificated form shall be the same as those of any
other Unitholder.  Certificates may be transferred as provided in Article VI.

     Section 2.04.  Form of Certificates.  Each Certificate referred to in
Section 2.03 is, and each Certificate hereafter issued shall be, in
substantially the form hereinabove recited, numbered serially for
identification, in fully registered form, transferable on the books of the
Trustee as herein provided, executed manually by an authorized signature of the
Trustee and by a facsimile signature of an Authorized Officer of the Depositor
and dated the date of execution and delivery by the Trustee.

                                  Article III

                             Administration of Fund

     Section 3.01.  Certain Moneys to be Credited to Income Account. The
Trustee shall collect any dividends or other like cash distributions on the
Securities in each Trust Fund as such becomes payable (including all monies
representing penalties for the failure to make timely payments on the
Securities, or as liquidated damages for default or breach of any condition or
term of the Securities or of the underlying instrument relating to any
Securities and other income attributable to a Special Security for which no New
Security has been obtained pursuant to

                                     -13-
<PAGE>

Section 3.10 hereof) and credit such income to a separate account for each Trust
Fund to be known as the "Income Account."

     Any non-cash distributions (other than a non-taxable distribution of the
shares of the distributing corporations which shall be retained by a Trust Fund)
received by a Trust Fund shall be dealt with in the manner described at Section
3.08, herein, and shall be retained or disposed of by such Trust Fund according
to those provisions.  The proceeds of any disposition shall be credited to the
Income Account of a Trust Fund.  Neither the Trustee nor the Depositor shall be
liable or responsible in any way for depreciation or loss incurred by reason of
any such sale.

     Section 3.02.  Certain Moneys to be Credited to Capital Account. (a) With
respect to each Trust Fund all moneys (except moneys held by the Trustee
pursuant to subsection (b) hereof) other than amounts credited to the Income
Account received by the Trustee in respect of the Securities under this
Agreement shall be credited to a separate account for each Trust Fund to be
known as the "Capital Account."

     (b) Moneys and/or irrevocable letters of credit required to purchase
Contract Securities or to purchase Securities pursuant to the Depositor's
written instructions, or deposited to secure such purchases, are hereby declared
to be held specially by the Trustee for such purchases and shall not be deemed
to be part of the Capital Account until (1) the Depositor fails to timely
purchase a Contract Security and has not given the Failed Contract Notice (as
defined in Section 3.10) at which time the moneys and/or letters of credit
attributable to the Contract Security not purchased by the Depositor shall be
credited to the Capital Account; or (2) the Depositor has given the Trustee the
Failed Contract Notice at which time the moneys and/or letters of credit
attributable to failed contracts referred to in such Notice shall be credited to
the Capital Account; provided, however, that if the Depositor also notifies the
Trustee in the Failed Contract Notice (or by separate notice delivered
concurrently with or prior to the Failed Contract Notice) that it has purchased
or entered into a contract to purchase a New Security (as defined in Section
3.10), the Trustee shall not credit such moneys and/or letters of credit to the
Capital Account unless the New Security shall also have failed or is not
delivered by the Depositor within two business days after the settlement date of
such New Security, in which event the Trustee shall forthwith credit such moneys
and/or letters of credit to the Capital Account.  The Depositor shall in any
case forthwith pay to the Trustee and the Trustee shall credit to the Capital
Account the difference, if any, between the purchase price of the failed
Contract Security and the purchase price of the New Security, together with any
sales charge and distribute such moneys to Unitholders pursuant to Section 3.04.

     Section 3.03.  Establishment of Reserve Account.  From time to time the
Trustee may withdraw from the Income or Capital Accounts of each Trust Fund
such amounts as it, in its sole discretion, shall deem requisite to establish a
reserve for any applicable taxes or other governmental charges that may be
payable out of such Trust Fund or for indemnification or extraordinary expenses
of the Depositor or Trustee pursuant to Section 7.02, 8.01 or 8.05.  Such
amounts so withdrawn shall be credited to a separate account for such Trust Fund
which shall be known as the "Reserve Account."  The Trustee shall not be
required to distribute to the Unitholders any of the amounts in the Reserve
Account; provided, however, that if it, in its sole discretion, determines that
such amounts are no longer necessary, then it shall promptly deposit

                                     -14-
<PAGE>

such amounts in the account from which withdrawn, or if such Trust Fund has been
terminated or shall be in the process of termination, the Trustee, upon such
determination, shall distribute to each Unitholder of such Trust Fund such
holder's interest in the Reserve Account in accordance with Section 9.01.

     Section 3.04.  Certain Deductions and Distributions.  (a) On or about the
last business day of each month, or at such other time as may be specified in
the Prospectus, the Trustee shall separately with respect to each Trust Fund:

            (1) deduct from the Income Account or, to the extent funds are not
     available in such Account, from the Capital Account and pay to itself
     individually the amounts that it is at the time entitled to receive
     pursuant to Section 8.05 on account of its services theretofore performed
     and expenses theretofore incurred;

            (2) deduct from the Income Account, or, to the extent funds are not
     available in such Account, from the Capital Account, and reimburse itself
     for any other fees, advances and expenses arising from time to time out of
     the Trust Fund operations that the Trustee has paid;

            (3) deduct from the Income Account or, to the extent funds are not
     available in such Account, from the Capital Account and pay to the
     Evaluator the amounts that the Evaluator is at the time entitled to receive
     pursuant to Section 4.03 on account of its services theretofore performed
     and expenses theretofore incurred;

            (4) deduct from the Income Account or, to the extent funds are not
     available in such Account, from the Capital Account and pay to counsel an
     amount equal to unpaid fees and expenses, if any, of counsel pursuant to
     Section 3.07 as certified by the Depositor;

            (5) deduct from the Income Account, or, to the extent funds are not
     available in such Account, from the Capital Account and pay to the
     Depositor the amounts that the Depositor is at the time entitled to receive
     pursuant to Section 3.11 on account of its services theretofore performed
     and expenses theretofore incurred; and

            (6) deduct from the Income Account or, to the extent funds are not
     available in such Account, from the Capital Account and pay to the
     Depositor the amount that it is entitled to receive pursuant to Section
     3.13.

     The amounts paid to the Trustee, Evaluator and the Depositor pursuant to
Sections 3.11, 3.13, 4.03 and 8.05, shall accrue daily and, until the Trustee is
notified by the Depositor that the primary offering period has terminated, where
applicable, be based upon the number of Units outstanding on each day.  After
the primary offering period has terminated, the fees, where applicable, shall
accrue daily and be based on the number of Units outstanding on the first
business day of each calendar year in which the fee is calculated or the number
of Units outstanding at the end of the primary offering period, as appropriate.

                                     -15-

     (b) The Trustee shall for each Trust Fund as of the close of business on
the applicable Record Date compute the amount of the income distribution per
Unit for the next Income Distribution Date (each such amount being herein called
the "Income Distribution") (1) by deducting from the amount actually received
with respect to dividends on the Securities in the Trust Fund during the period
from the Record Date preceding such Record Date (or the Initial Date of Deposit
if such Record Date is the first Record Date) to and including such Record Date
the total of (i) the amounts to be deducted from the Income Account of such
Trust Fund as of such Record Date pursuant to the foregoing provisions of
Section 3.04(a) and (ii) the Trustee's estimate of other expenses properly
chargeable to the Income Account pursuant to the Agreement which have accrued,
as of such Record Date, or are otherwise properly attributable to the period to
which such Income Distribution relates and (2) by dividing the result of the
calculation performed pursuant to the immediately preceding clause by the number
of Units outstanding on the applicable Record Date.  On or shortly after each
Income Distribution Date, the Trustee shall distribute with respect to each
Unitholder of the Trust Fund of record at the close of business on the preceding
Record Date an amount substantially equal to the Income Distribution computed as
of such Record Date.

     To the extent that moneys in the Capital Account have not been previously
used to pay for the redemption of Units tendered to a Trust Fund, on the Capital
Distribution Dates each Unitholder shall receive such holder's pro rata share of
the cash balance of the Capital Account of the Trust Fund computed as of the
close of business on the preceding Record Date for such Capital Distribution
Date by (1) deducting from such cash balance the total of (i) cash required to
cover contracts to purchase Securities, (ii) cash required for the redemption of
unredeemed tendered Units and (iii) the sum of the amounts to be deducted from
the Capital Account as of each such Record Date pursuant to the foregoing
provisions of Section 3.04(a) and (2) dividing the amount so obtained by the
number of Units outstanding on the Record Date immediately preceding such
Capital Distribution Date.  Notwithstanding anything to the contrary contained
in this paragraph, if a Trust Fund has elected to be treated as a "regulated
investment company" as defined in the Internal Revenue Code and the Trust Fund's
portfolio is based upon an index, the Depositor or its designee may, but is not
obligated to, direct the investment of any amounts held in the Capital Account
that have not previously been used to pay for the redemption of Units tendered
to a Trust Fund into any Securities included in the applicable index.

     In making the computation of any Unitholder's interest in the balance of
the Income and Capital Accounts, fractions of less than one cent per Unit shall
be omitted.  In addition, the Trustee in its discretion may on any Distribution
Date determine that the amount to be distributed to Unitholders should be more
or less than the amount of the applicable Income or Capital Distribution per
Unit because of any unusual or extraordinary increase or decrease in the
expenses incurred or expected to be incurred by such Trust Fund.  The Trustee
shall not be obligated to make a distribution from the Capital Account if the
amount available for such distribution is less than $1.00 per 100 Units.  When
directed by the Depositor, the Trustee shall invest funds held in the Capital or
Income Accounts, pending distribution, in money market mutual funds or U.S.
Treasury obligations which mature on or before the next applicable distribution
date.  Any obligations so acquired must be held until they mature and proceeds
therefrom may not be reinvested.

     (c) If the Depositor fails to replace any failed Special Security (as
defined in Section 3.10), the Trustee shall distribute to all Unitholders the
moneys originally deposited with respect to such Special Security and, to the
extent supplied by the Depositor, the sales charge attributable to such Special
Security not more than 30 days after the expiration of the Purchase Period (as
defined in Section 3.10).  If any contract for a New Security in replacement of
a Special Security shall fail, the Trustee shall distribute the moneys
originally deposited with respect to such Special Security and, to the extent
provided by the Depositor, the sales charge attributable to the Special Security
to the Unitholders not more than 30 days after the date on which the contract in
respect of such New Security failed.  If at the end of the Purchase Period less
than all moneys attributable to a failed Special Security have been applied or
allocated by the Trustee pursuant to a contract to purchase New Securities, the
Trustee shall distribute the remaining moneys (1) to Unitholders not more than
30 days after the end of the Purchase Period to the extent the failed Special
Security has not been fully replaced by New Securities or (2) to the Depositor
to the extent moneys remain after the purchase of the New Securities, if any,
and the distribution referred to in clause (1).

     (d) Except as provided below, all distributions shall be made by first
class mail to each Unitholder of record at the close of business on the
preceding applicable Record Date at the address of such holder appearing on the
registration books of the Trustee provided, however, that the Trustee shall if
so directed with respect to distributions from the Income and/or Capital Account
at the time of purchase of Units or thereafter in writing signed by the
Unitholder and timely received, make such distributions to the Program Agent.  A
Unitholder's written notice must be received by the Program Agent at least ten
days prior to the Record Date for the next Income Distribution in order to be in
effect for such Income Distribution.  All such notices shall remain in effect
until a subsequent notice is received by the Program Agent.  Upon receipt of any
such distribution the Program Agent shall, if the respective Trust Fund
Prospectus so provides, either (1) reinvest such Unitholder's distribution from
the Income and/or Capital Accounts in Units of the Trust, purchased from the
Depositor, to the extent the Depositor shall make Units available for such
purchase, at the Depositor's offering price as of the third business day prior
to the following Distribution Date, and at such reduced sales charge as may be
described in the Prospectus for the Trust Fund or (2) purchase shares (or
fractions thereof) in the applicable reinvestment fund as directed by the
Unitholder.  If, for any reason, the Depositor does not have Units of the Trust
Fund available for purchase, the Trustee shall distribute such Unitholder's
distributions from the Income and/or Capital Accounts in the manner provided in
the first sentence of this Section 3.04(d).  The Program Agent shall not be
liable to any Unitholder for any action taken with respect to its duties and
responsibilities as Program Agent; or for any failure to make such reinvestment
in the event the Depositor does not make Units available for purchase provided,
however, that this provision shall not protect the Program Agent against
liability to which it would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence in the performance of its duties or
by reason of its reckless disregard of its obligations and duties hereunder.

     (e) Except as provided by the preceding paragraph, Unitholders of record
on the registration books of the Trustee at the close of business on the Record
Date prior to each Distribution Date, shall be entitled to the distribution in
respect of such Distribution Date, and, except as provided in Article VIII, no
liability shall attach to the Trustee by reason of payment to

                                     -17-
<PAGE>

or on the order of any such Unitholder of record. Nothing herein shall be
construed to prevent the payment of distributions from the Income and Capital
Accounts to any such Unitholder by means of one check, draft or other proper
instrument.

     (f) Notwithstanding the foregoing, if a Trust Fund has elected to be
treated as a "regulated investment company" as defined in the Internal Revenue
Code, the Trustee may make such additional distributions to Unitholders as shall
be determined by the Depositor or such agent as the Depositor shall designate to
be necessary or desirable to maintain the status of each Trust Fund as a
regulated investment company or to avoid imposition of any income or excise
taxes on undistributed income of the Trust Fund.  The Trustee shall be
authorized to rely conclusively upon the direction, and shall have no duty to
make any additional distributions from a Trust Fund in the absence of such
direction.  The Trustee shall have no liability for any tax or other liability
incurred by reason of action or inaction resulting from such direction.  The
fees of such agent designated by the Depositor shall be an expense of the Trust
Funds reimbursable to the Trustee in accordance with Section 8.05.

     Section 3.05.  Statements and Reports.  With each distribution from the
Income or Capital Accounts of each Trust Fund the Trustee shall set forth,
either in the instrument by means of which payment of such distribution is made
or in an accompanying statement, the amount being distributed from each such
account expressed as a dollar amount per Unit of such Trust Fund.  If the
distribution is an In Kind Distribution, the Trustee shall provide a list of the
Securities being distributed, the aggregate number of shares of each Security
being distributed and any cash representing fractional shares being distributed.
Within a reasonable period of time after the last business day of each calendar
year, the Trustee shall furnish to each person who at any time during such
calendar year was a Unitholder of any individual Trust Fund a statement for such
Trust Fund setting forth with respect to such calendar year:

          (A)  as to the Income Account:

               (1) the amount of dividends received on the Securities;

               (2) the amounts paid for purchases of New Securities pursuant to
          Section 3.10 and for redemptions pursuant to Section 5.02;

               (3) the deductions for applicable taxes and fees and expenses of
          the Trust;

               (4) the reservations made by the Trustee pursuant to Section
          3.03, if any; and

               (5) the balance remaining after such distributions, deductions
          and reservations expressed both as a total dollar amount and as a
          dollar amount per Unit outstanding on the last business day of such
          calendar year;

                                     -18-
<PAGE>

          (B)  as to the Capital Account:

               (1) the dates of sale or liquidation of any of the Securities
          and the net proceeds received therefrom (excluding any portion thereof
          credited to the Income Account);

               (2) the results of In Kind Distributions in connection with
          redemptions of Units, if any;

               (3) the amounts paid for purchases of New Securities pursuant to
          Section 3.10 and for redemptions pursuant to Section 5.02;

               (4) the deductions for payment of applicable taxes and fees and
          expenses of the Trust Fund;

               (5) the reservations made by the Trustee pursuant to Section
          3.03, if any; and

               (6) the balance remaining after such distributions, deductions
          and reservations, expressed both as a total dollar amount and as a
          dollar amount per Unit outstanding on the last business day of such
          calendar year; and

          (C)  the following information:

               (1) a list of the Securities as of the last business day of such
          calendar year;

               (2) the number of Units outstanding on the last business day of
          such calendar year;

               (3) the Unit Value based on the Trust Fund Evaluations made on
          the last day of December (or the last business day prior thereto) of
          such calendar year; and

               (4) the amounts actually distributed to Unitholders during such
          calendar year from the Income and Capital Accounts, separately stated,
          expressed both as total dollar amounts and as dollar amounts per Unit
          outstanding on the Record Dates for such distributions.

     Section 3.06.  Extraordinary Sale of Securities.  (a) If necessary, in
order to maintain the sound investment character of a Trust Fund, the Depositor
may direct the Trustee to sell or liquidate Securities in such Trust Fund at
such price and time and in such manner as shall be determined by the Depositor,
provided that the Depositor has determined that any one or more of the following
conditions exist:

                                     -19-
<PAGE>

          (1) that there has been a default on any of the Securities in the
     payment of dividends, after declared and when due and payable;

          (2) that any action or proceeding has been instituted at law or equity
     seeking to restrain or enjoin the payment of dividends on any such
     Securities, or that there exists any legal question or impediment affecting
     such Securities or the payment of dividends from the same;

          (3) that there has occurred any breach of covenant or warranty in any
     document relating to the issuer of the Securities which would adversely
     affect either immediately or contingently the payment of dividends from
     such Securities, or the general credit standing of the issuer or otherwise
     impair the sound investment character of such Securities;

          (4) that there has been a default in the payment of dividends,
     principal of or income or premium, if any, on any other outstanding
     obligations of the issuer of such Securities;

          (5) that the price of any such Securities had declined to such an
     extent or other such credit factors exist so that in the opinion of the
     Depositor, as evidenced in writing to the Trustee, the retention of such
     Securities would be detrimental to the Trust Fund and to the interest of
     the Unitholders; and

          (6) that there has been a public tender offer made for a Security or
     a merger or acquisition is announced affecting a Security, and that in the
     opinion of the Depositor the sale or tender of the Security is in the best
     interest of the Unitholders.

     Upon receipt of such direction from the Depositor, upon which the Trustee
shall rely, the Trustee shall proceed to sell or liquidate the specified
Securities in accordance with such direction, and upon the receipt of the
proceeds of any such sale or liquidation, after deducting therefrom any fees and
expenses of the Trustee connected with such sale or liquidation and any
brokerage charges, taxes or other governmental charges shall deposit such net
proceeds in the Capital Account.

     The Trustee shall not be liable or responsible in any way for depreciation
or loss incurred by reason of any sale made pursuant to any such direction or by
reason of the failure of the Depositor to give any such direction, and in the
absence of such direction the Trustee shall have no duty to sell or liquidate
any Securities under this Section 3.06 except to the extent otherwise required
by this Agreement.  The Depositor shall not be liable for errors of judgment in
directing or failing to direct the Trustee pursuant to this Section 3.06.  This
provision, however, shall not protect the Trustee or Depositor against any
liability for which they would otherwise be subject, respectively, by reason of
wilful misfeasance, bad faith or gross negligence in the performance of their
duties or by reason of their reckless disregard of their obligations and duties
hereunder.

     (b) If a Trust Fund has elected to be treated as a "regulated investment
company" as defined in the Internal Revenue Code, and not withstanding anything
to the contrary in 3.06(a),

                                     -20-
<PAGE>

the Depositor by written notice may direct the Trustee to sell Securities at
such price and time and in such manner as shall be deemed appropriate by the
Depositor if the Depositor shall have determined that any one or more of the
following conditions exist:

          (1) that there has been a default in the payment of principal of or
     interest on any outstanding debt obligations of the issuer of such
     Securities;

          (2) that the price of any such Security has declined to such an
     extent, as a result of adverse issuer credit factors, so that in the
     opinion of the Depositor the retention of such Securities would be
     detrimental to the interest of the Unitholders;

          (3) that such sale is necessary or advisable (i) to maintain the
     qualification of the Trust Fund as a regulated investment company or (ii)
     to provide funds to make any distribution for a taxable year in order to
     avoid imposition of any income or excise taxes on undistributed income in
     the Trust Fund;

          (4) that the Security has been removed from the applicable index; or

          (5) the Depositor or its designee determines that such sale is
     appropriate.

     Upon receipt of such direction from the Depositor, the Trustee shall
proceed to sell the specified Securities in such manner as the Depositor or its
designee shall direct.  If the Trust Fund's portfolio is based upon an index,
the Depositor or its designee may enter into contracts on behalf of the Trust
Fund to reinvest the proceeds of the sale of any Security sold pursuant to this
section, Section 5.02 or otherwise pursuant to this Agreement into any Security
included in the applicable index.  Without limiting the generality of the
foregoing, in determining whether such reinvestment is practicable, the
Depositor may, but is not obligated to, specifically consider the ability of the
Trust Fund to reinvest such proceeds into round lots of a Security.  Contracts
for sale or purchase of Securities shall be made by the Depositor on behalf of
the Trust Fund or by such agent as the Depositor shall designate.  The Depositor
or its designee shall provide the Trustee such information as the Trustee may
require in order to settle the transactions.  The Trustee shall not be liable or
responsible in any way for depreciation or loss incurred by reason of any sale
or purchase made pursuant to any such direction or by reason of the failure of
the Depositor to give any such direction, and in the absence of such direction
the Trustee shall have no duty to sell or purchase any Securities under this
Section 3.06 and shall have no responsibility for the composition of each Trust
Fund portfolio.  The Depositor shall not be liable for errors of judgment in
directing or failing to direct the Trustee pursuant to this Section 3.06.  This
provision, however, shall not protect the Depositor against any liability for
which it would otherwise be subject, by reason of willful misfeasance, bad faith
or gross negligence in the performance of its duties or by reason of its
reckless disregard of its obligations and duties hereunder.

     The Depositor or its designated agent shall make such reviews of each Trust
Fund portfolio as shall be necessary to maintain qualification of a particular
Trust Fund as a regulated investment company and the Depositor shall be
authorized to rely conclusively upon such reviews in directing sales pursuant to
paragraph (3) of this section.

                                     -21-

     Section 3.07.  Counsel.  The Depositor may employ from time to time counsel
to act on behalf of any Trust Fund for any legal services in connection with the
Securities, and any legal matters relating to the possible disposition of any
Securities pursuant to any provisions hereof. The fees and expenses of such
counsel shall be paid by the Trustee as provided in Section 3.04(a)(4) hereof.

     Section 3.08.  Action by Trustee Regarding Securities.  In the event that
the Trustee shall have been notified at any time of any action to be taken or
proposed to be taken by holders of the Securities the Trustee shall promptly
notify the Depositor and shall thereupon take such action or refrain from taking
any action as the Depositor shall in writing direct; provided, however, that if
the Depositor shall not within five business days of the giving of such notice
to the Depositor direct the Trustee to take or refrain from taking any action,
the Trustee shall take such action as it, in its sole discretion, shall deem
advisable. In connection with any solicitation of proxies by management of any
of the Securities in the Trust Fund, if the Depositor fails to instruct the
Trustee how to vote such proxy, the Trustee shall vote with the recommendation
of such management. Except as provided in Article VII and Article VIII, neither
the Depositor nor the Trustee shall be liable to any person for any action or
failure to take action with respect to this Section 3.08.

     In the event that an offer by the issuer of any of the Securities or any
other party shall be made to issue new securities, or to exchange securities,
for Trust Fund Securities, the Trustee shall reject such offer.  However, should
any issuance, exchange or substitution be effected notwithstanding such
rejection or without an initial offer, any securities, cash and/or property
received shall be promptly sold, if securities or property, by the Trustee
pursuant to the Depositor's direction, unless the Depositor advises the Trustee
to keep such securities or property.  The cash received in such exchange and
cash proceeds of any such sales shall be distributed to Unitholders on the next
distribution date in the manner set forth in Section 3.04(b) regarding
distributions from the Capital Account.  Except as provided in Article VIII, the
Trustee shall not be liable or responsible in any way for depreciation or loss
incurred by reason of any such sale.

     Notwithstanding the preceding paragraph, if a Trust Fund has elected to be
treated as a "regulated investment company" as defined in the Internal Revenue
Code, in the event that an offer by the issuer of any of the Securities or any
other party shall be made to issue new securities, or to exchange securities,
for Trust Fund Securities, the Trustee shall reject such offer.  However, should
any issuance, exchange or substitution be effected notwithstanding such
rejection or without an initial offer, any securities, cash and/or property
received shall be deposited hereunder and shall be promptly sold, if securities
or property, by the Trustee pursuant to the Depositor's direction, unless the
Depositor advises the Trustee to keep such securities or property; provided,
however, if the Trust Fund's portfolio is based upon an index, and such
securities are components of the applicable index, the Depositor may advise the
Trustee to keep such securities.  The cash received in such exchange and cash
proceeds of any such sales shall, as the Depositor or its designee shall direct,
be (1) reinvested into any Securities included in the applicable index, if the
Trust Fund's portfolio is based upon an index, or (2) distributed to Unitholders
on the next Capital Distribution Date in the manner set forth in this Agreement
regarding distributions from the Capital Account.  Without limiting the
generality of the

                                     -22-
<PAGE>

foregoing, in determining whether such reinvestment is practicable, the
Depositor may, but is not obligated to, specifically consider the ability of a
Trust Fund to reinvest such proceeds into round lots of a Security. Except as
provided in Article VIII, the Trustee shall not be liable or responsible in any
way for depreciation or loss incurred by reason of any such rejection or sale.

     Any non-cash distributions (other than a non-taxable distribution of the
shares of the distributing corporation which shall be retained by a Trust Fund)
received by a Trust Fund shall be dealt with in the manner described above and
shall be retained or disposed of according to such provisions.

     Neither the Depositor nor the Trustee shall be liable to any person for any
action or failure to take action pursuant to the terms of this Section 3.08.

     Whenever new securities or property is received and retained by a Trust
Fund pursuant to this Section 3.08, the Trustee shall, within a reasonable
amount of time thereafter, mail to all Unitholders of such Trust Fund notices of
such acquisition unless legal counsel for such Trust Fund determines that such
notice is not required by The Investment Company Act of 1940, as amended.

     Section 3.09.  Notice of Change in Capital Account.  The Trustee shall give
prompt written notice to the Depositor and the Evaluator of all amounts credited
to or withdrawn from the Capital Account of any Trust Fund pursuant to any of
the provisions of this Article III and the balance in such Account after giving
effect to the credit or withdrawal.

     Section 3.10.  Limited Replacement of Special Securities.  If any contract
in respect of Contract Securities other than a contract to purchase a New
Security (as defined below), including those purchased on a delayed delivery
basis, shall have failed due to any occurrence, act or event beyond the control
of the Depositor or the Trustee (such failed Contract Securities being herein
called the "Special Securities"), the Depositor shall notify the Trustee (such
notice being herein called the "Failed Contract Notice") of its inability to
deliver the failed Special Security to the Trustee after it is notified that the
Special Security will not be delivered by the seller thereof to the Depositor.
Prior to, or simultaneously with, giving the Trustee the Failed Contract Notice,
or within a maximum of 20 days after giving such Failed Contract Notice (such 20
day period being herein called the "Purchase Period"), the Depositor shall, if
possible, purchase, or enter into a contract to purchase, an obligation to be
held as a Security hereunder (herein called the "New Security") as part of the
Trust Fund in replacement of the failed Special Security, subject to the
satisfaction of all of the following conditions in the case of each purchase or
contract to purchase:

          (a) The New Securities shall be equity securities and shall, in the
     opinion of the Depositor, be of the same general quality as those
     Securities originally deposited.  Notwithstanding the foregoing, if a Trust
     Fund has elected to be treated as a "regulated investment company," as
     defined in the Internal Revenue Code and the Trust Fund's portfolio is
     based upon an index, the New Securities shall be a component of the
     applicable index.

                                     -23-
<PAGE>

          (b) The purchase price of the New Securities shall not exceed the
     amount of funds reserved for the purchase of the Special Securities.

          (c) The Depositor shall furnish a notice to the Trustee (which may be
     part of the Failed Contract Notice) in respect of the New Security
     purchased or to be purchased that shall (1) identify the New Securities,
     (2) state that the contract to purchase, if any, entered into by the
     Depositor is satisfactory in form and substance and (3) state that the
     foregoing conditions of clauses (a) and (b) have been satisfied with
     respect to the New Securities.

          (d) Notwithstanding the foregoing clauses (b) and (c), if a Trust
     Fund has elected to be treated as a "regulated investment company," as
     defined in the Internal Revenue Code, the Depositor shall furnish a notice
     to the Trustee (which may be part of the Failed Contract Notice) in respect
     to the New Security purchased or to be purchased that shall (1) identify
     the New Securities, (2) state that the contract to purchase, if any,
     entered into by the Depositor is satisfactory in form and substance and (3)
     state that the foregoing conditions of clause (a) have been satisfied with
     respect to the New Securities.

     Upon satisfaction of the foregoing conditions with respect to any New
Security, the Trustee shall pay the purchase price for the New Security from the
amount of funds reserved for the purchase of the Special Securities or, if the
Trustee has credited any moneys and/or letters of credit attributable to the
failed Special Security to the Capital Account, the Trustee shall pay the
purchase price of the New Security upon directions from the Depositor from the
moneys and/or letters of credit so credited to the Capital Account.  If the
Trustee has credited moneys of the Depositor to the Capital Account, the Trustee
shall forthwith return to the Depositor the portion of such moneys that is not
properly distributable to Unitholders pursuant to Section 3.04.

     Whenever a New Security is acquired by the Depositor pursuant to the
provisions of this Section 3.10, the Trustee shall, within five days thereafter,
mail to all Unitholders notices of such acquisition, including an identification
of the failed Special Securities and the New Securities acquired.  The purchase
price of the New Securities shall be paid out of the funds reserved for the
purchase of the failed Special Securities.  Except as provided in Article VIII,
the Trustee shall not be liable or responsible in any way for depreciation or
loss incurred by reason of any purchase made pursuant to any such directions and
in the absence of such directions the Trustee shall have no duty to purchase any
New Securities under this Agreement.  The Depositor shall not be liable for any
failure to instruct the Trustee to purchase any New Securities or for errors of
judgment in respect of this Section 3.10; provided, however, that this provision
shall not protect the Depositor against any liability to which it would
otherwise be subject by reason of willful misfeasance, bad faith or negligence
in the performance of its duties or by reason of its reckless disregard of its
obligations and duties hereunder.

     Section 3.11.  Compensation of Depositor for Supervisory Services. As
compensation for providing supervisory portfolio services under this Agreement,
the Depositor shall receive at the time specified in Section 3.04, against a
statement or statements therefor submitted to the Trustee, an aggregate annual
fee if so provided and in the amount specified as compensation for the Depositor
in the Prospectus, calculated as specified in Section 3.04, but in no event
shall such

                                     -24-
<PAGE>

compensation when combined with all compensation received from other series of
the Fund or other unit investment trusts sponsored by the Depositor or its
affiliates for providing such supervisory services in any calendar year exceed
the aggregate cost to the Depositor for providing such services. The rate of
such compensation may be increased by the Depositor from time to time, without
the consent or approval of any Unitholder or the Trustee, by amounts not
exceeding the proportionate increase, during the period from the date of the
Trust Agreement to the date of any such increase, in consumer prices as last
published prior to each such date under the classification "All Services Less
Rent of Shelter" in the Consumer Price Index For All Urban Consumers (CPI-U)
U.S. City Average, not seasonally adjusted, base 1982 - 84 = 100, published by
the United States Department of Labor. In the event that such classification
ceases to incorporate a significant number of items, or if a substantial change
is made in the method of establishing such classification, then the
classification shall be adjusted in a fair and reasonable manner to the figure
that would have resulted had no substantial change occurred in the manner of
computing such classification. In the event that such classification (or a
successor or substitute index) is not available, such governmental or other
service or publication as shall evaluate the information in substantially the
same manner as the aforesaid classification, shall be used in lieu thereof. Such
compensation shall be charged by the Trustee, upon receipt of invoice therefor
from the Depositor, against the Income and Capital Accounts as specified in
Section 3.04. If the cash balance in the Income and Capital Accounts shall be
insufficient to provide for amounts payable pursuant to this Section 3.11, the
Trustee shall have the power to sell (i) Securities from the current list of
Securities designated to be sold pursuant to Section 5.02 hereof, or (ii) if no
such Securities have been so designated, such Securities as the Trustee may see
fit to sell in its own discretion, and to apply the proceeds of any such sale in
payment of the amounts payable pursuant to this Section 3.11. Any moneys payable
to the Depositor pursuant to this Section 3.11 shall be secured by a prior lien
on the Trust Fund except that such lien shall be junior and subordinate to any
lien in favor of the Trustee under the provisions of Section 8.08 and of the
Evaluator under the provisions of Section 4.03.

     Section 3.12.  Deferred Sales Charge.  If the Prospectus related to a Trust
Fund specifies a deferred sales charge, the Trustee shall, on the dates
specified in and as permitted by such Prospectus (the "Deferred Sales Charge
Payment Dates"), withdraw from the Capital Account, an amount per Unit specified
in such Prospectus and credit such amount to a special non-Trust account
designated by the Depositor out of which the deferred sales charge will be
distributed to or on the order of the Depositor on such Deferred Sales Charge
Payment Dates (the "Deferred Sales Charge Account").  If the balance in the
Capital Account is insufficient to make such withdrawal, the Trustee shall, as
directed by the Depositor, advance funds in an amount required to fund the
proposed withdrawal and be entitled to reimbursement of such advance upon the
deposit of additional monies in the Capital Account, and/or sell Securities and
credit the proceeds thereof to the Deferred Sales Charge Account, provided,
however, that the aggregate amount advanced by the Trustee at any time for
payment of the deferred sales charge shall not exceed $15,000.  Such direction
shall, if the Trustee is directed to sell a Security, identify the Security to
be sold and include instructions as to the execution of such sale.  In the
absence of such direction by the Depositor, the Trustee shall sell Securities
sufficient to pay the deferred sales charge (and any unreimbursed advance then
outstanding) in full, and shall select Securities to be sold in such manner as
will maintain (to the extent practicable) the relative proportion of number of
shares of each Security then held.  The proceeds of such sales, less any amounts
paid to the Trustee in

                                     -25-
<PAGE>

reimbursement of its advances, shall be credited to the Deferred Sales Charge
Account. If a Unitholder redeems Units prior to full payment of the deferred
sales charge, the Trustee shall, if so provided in the related Prospectus, on
the Redemption Date, withhold from the Redemption Price payable to such
Unitholder an amount equal to the unpaid portion of the deferred sales charge
and distribute such amount to the Deferred Sales Charge Account. If the Trust
Fund is terminated for reasons other than that set forth in Section 8.01(g)(ii),
the Trustee shall, if so provided in the related Prospectus, on the termination
of the Trust Fund, withhold from the proceeds payable to Unitholders an amount
equal to the unpaid portion of the deferred sales charge and distribute such
amount to the Deferred Sales Charge Account. If the Trust Fund is terminated
pursuant to Section 8.01(g)(ii), the Trustee shall not withhold from the
proceeds payable to Unitholders any amounts of unpaid deferred sales charges. If
pursuant to Section 5.02 hereof, the Depositor shall purchase a Unit tendered
for redemption prior to the payment in full of the deferred sales charge due on
the tendered Unit, the Depositor shall pay to the Unitholder the amount
specified under Section 5.02 less the unpaid portion of the deferred sales
charge. All advances made by the Trustee pursuant to this Section shall be
secured by a lien on the Trust Fund prior to the interest of the Unitholders.
The Depositor represents that the price paid by any Unitholder for Units
acquired through reinvestment of Trust Fund distributions will be reduced by the
aggregate amount of unpaid deferred sales charges at the time of the purchase to
offset any subsequent collection by the Depositor of deferred sales charges in
respect of the Units so acquired.

     Section 3.13.  Bookkeeping and Administrative Expenses.  If so provided in
the Prospectus, as compensation for providing bookkeeping and other
administrative services of a character described in Section 26(a)(2)(C) of the
Investment Company Act of 1940 to the extent such services are in addition to,
and do not duplicate, the services to be provided hereunder by the Trustee or
the Depositor for providing supervisory services, the Depositor shall receive at
the times specified in Section 3.04, against a statement or statements therefor
submitted to the Trustee an aggregate annual fee in an amount which shall not
exceed that amount set forth in the Prospectus, calculated as specified in
Section 3.04, but in no event shall such compensation, when combined with all
compensation received from other series of the Fund or other unit investment
trusts sponsored by the Depositor or its affiliates for providing such
bookkeeping and administrative services in any calendar year exceed the
aggregate cost to the Depositor for providing such services to such unit
investment trusts.  Such compensation may, from time to time, be adjusted
provided that the total adjustment upward does not, at the time of such
adjustment, exceed the percentage of the total increase, during the period from
the Trust Agreement to the date of any such increase, in consumer prices for
services as measured by the United States Department of Labor Consumer Price
Index entitled "All Services Less Rent of Shelter" or similar index as described
under Section 3.11.  The consent or concurrence of any Unitholder hereunder
shall not be required for any such adjustment or increase.  Such compensations
shall be paid by the Trustee, upon receipt of invoice therefor from the
Depositor, upon which, as to the cost incurred by the Depositor of providing
services hereunder the Trustee may rely, and shall be charged against the Income
and Capital Accounts as specified in Section 3.04.  The Trustee shall have no
liability to any Unitholder or other person for any payment made in good faith
pursuant to this Section.

                                     -26-
<PAGE>

     If the cash balance in the Income and Capital Accounts shall be
insufficient to provide for amounts payable pursuant to this Section 3.13, the
Trustee shall have the power to sell (1) Securities from the current list of
Securities designated to be sold pursuant to Section 5.02 hereof, or (2) if no
such Securities have been so designated, such Securities as the Trustee may see
fit to sell in its own discretion, and to apply the proceeds of any such sale in
payment of the amounts payable pursuant to this Section 3.13.

     Any moneys payable to the Depositor pursuant to this Section 3.13 shall be
secured by a prior lien on the Trust except that no such lien shall be prior to
any lien in favor of the Trustee under the provisions of Section 8.08 and of the
Evaluator under the provisions of Section 4.03.

     Section 3.14.  License Fees.  If so provided in the Prospectus, the
Depositor may enter into a Licensing Agreement (the "Agreement") with a licensor
(the "Licensor") described in the Prospectus in which a Trust Fund, as
consideration for the licenses granted by the Licensor for the right to use its
trademarks, trade names and/or service marks, intellectual property rights or
for the use of databases and research owned by the Licensor, will pay a fee set
forth in the Agreement to the applicable Licensor or the Depositor to reimburse
the Depositor for payment of the expenses.

     If the Agreement provides for an annual license fee computed in whole or
part by reference to the average daily net asset value of the Trust Fund assets,
for purposes of calculating the accrual of estimated expenses such annual fee
shall accrue at a daily rate and the Trustee is authorized to compute an
estimated license fee payment (a) until the Depositor has informed the Trustee
that there will be no further deposits of additional Securities, by reference to
an estimate of the average daily net asset value of the Trust Fund assets which
the Depositor shall provide the Trustee, (b) thereafter and during the calendar
quarter in which the last business day of the period described in clause (a)
occurs, by reference to the net asset value of the Trust Fund assets as of such
last business day, and (c) during each subsequent calendar quarter, by reference
to the net asset value of the Trust Fund assets as of the last business day of
the preceding calendar quarter.  The Trustee shall adjust the net asset value
(Trust Fund Evaluation) as of the dates specified in the preceding sentence to
account for any variation between accrual of estimated license fees and the
license fees payable pursuant to the Agreement, but such adjustment shall not
affect calculations made prior thereto and no adjustment shall be made in
respect thereof.

     Section 3.15.  Creation and Development Fee.  If the Prospectus related to
a Trust Fund specifies a Creation and Development Fee, the Trustee shall, on the
last day of each month, withdraw from the Capital Account an amount equal to the
accrued and unpaid Creation and Development Fee as of such date and credit such
amount to a special non-Trust account designated by the Depositor out of which
the Creation and Development Fee will be distributed to the Depositor (the
"Creation and Development Account"). The Creation and Development Fee will
accrue on a daily basis at an annual rate as set forth in the Prospectus for a
Trust Fund based on a percentage of the average daily net asset value of the
Trust Fund. If the balance in the Capital Account is insufficient to make such
withdrawal, the Trustee shall, as directed by the Depositor, advance funds in an
amount required to fund the proposed withdrawal and be entitled to reimbursement
of such advance upon the deposit of additional monies in the Capital Account,
and/or sell Securities and credit the proceeds thereof to the Creation and
Development Account,

                                     -27-
<PAGE>

provided, however, that the aggregate amount advanced by the Trustee at any time
for payment of the Creation and Development Fee shall not exceed $15,000. Such
direction shall, if the Trustee is directed to sell a Security, identify the
Security to be sold and include instructions as to the execution of such sale.
In the absence of such direction by the Depositor, the Trustee shall sell
Securities sufficient to pay the Creation and Development Fee (and any
unreimbursed advance then outstanding) in full, and shall select Securities to
be sold in such manner as will maintain (to the extent practicable) the relative
proportion of the number of shares of each Security then held. The proceeds of
such sales, less any amounts paid to the Trustee in reimbursement of its
advances, shall be credited to the Creation and Development Account. If a Trust
Fund is terminated pursuant to Section 8.01(g), the Depositor agrees to
reimburse the Unitholders for any amounts of the Creation and Development Fee
collected by the Depositor to which it is not entitled. All advances made by the
Trustee pursuant to this Section shall be secured by a lien on the Trust Fund to
the interest of Unitholders. Notwithstanding the foregoing, the Depositor shall
not receive any amount of the Creation and Development Fee which exceeds the
maximum amount per Unit stated in the Prospectus. The Depositor shall notify the
Trustee not later than ten business days prior to the date on which it
anticipates that the maximum amount of the Creation and Development Fee it may
receive has been accrued and shall also notify the Trustee as of the date when
the maximum amount of the Creation and Development Fee has been accrued. The
Trustee shall have no responsibility or liability for damages or loss resulting
from any error in the information provided by the Depositor, or the Depositor's
failure to provide the information, specified in the preceding sentence. The
Depositor agrees to reimburse the Trust Fund and any Unitholder any amount of
the Creation and Development Fee it receives which exceeds the amount which the
Depositor may receive under applicable laws, regulations and rules.

     Section 3.16  Foreign Currency Exchange.  Unless the Depositor shall
otherwise direct, whenever funds are received by the Trustee in foreign
currency, upon the receipt thereof or, if such funds are to be received in
respect of a sale of Securities, concurrently with the contract of the sale for
the Security (in the latter case the foreign exchange contract to have a
settlement date coincident with the relevant contract of sale for the Security),
the Trustee shall enter into a foreign exchange contract for the conversion of
such funds to U.S. dollars pursuant to the instruction of the Depositor.  The
Trustee shall have no liability for any loss or depreciation resulting from
action taken pursuant to such instruction.

     Section 3.17.  Regulated Investment Company Election.  If so provided in
the Prospectus for a Trust Fund, such Trust Fund elects to be treated and to
qualify as a "regulated investment company" as defined in the Internal Revenue
Code, and the Trustee is hereby directed to make such elections, including any
appropriate election to be taxed as a corporation, as shall be necessary to
effect such qualification.

                                   Article IV

                    Evaluation of Securities; The Evaluator

     Section 4.01.  Evaluation of Securities.  The Evaluator shall determine
separately and promptly furnish to the Trustee and the Depositor upon request
the value of each issue of Securities as of the Evaluation Time as provided in
the following manner:

          (a) The Evaluator will prepare each evaluation for which market
     quotations for the Securities are available by the use of outside services
     normally used and contracted with for this purpose.  If the Securities are
     listed on a national or foreign securities exchange or The NASDAQ Stock
     Market, Inc., the evaluation will be based on the closing sale price on the
     exchange or system where the Securities are principally traded (if a
     Security is listed on the New York Stock Exchange, the closing sale price
     on that exchange shall apply) or, if there is no closing sale price on the
     exchange or system, at the closing bid price on the exchange or system.  If
     such market quotations are not available, the Evaluator shall determine the
     value of the Securities.  Such evaluation shall generally be based on the
     current bid prices on the over-the-counter market (unless it is determined
     that these prices are inappropriate as a basis for evaluation).  If such
     prices are not available on the over-the-counter market, the evaluation
     will generally be made by the Evaluator in good faith (1) on the basis of
     the current bid prices for comparable securities, (2) by the Evaluator's
     appraising the value of the Securities in good faith at the bid side of the
     market or (3) by any combination thereof.  If such prices are in a currency
     other than U.S. dollars, the Evaluation of such Security shall be converted
     to U.S. dollars based on current bid side exchange rates, unless the
     Security is in the form of an American Depositary Share or Receipt, in
     which case the Evaluations shall be based upon the U.S. dollar prices in
     the market for American Depositary Shares or Receipts (unless the Evaluator
     deems such prices inappropriate as a basis for valuation).  As used herein,
     the closing sale price is deemed to mean the most recent closing sale price
     on the relevant securities exchange immediately prior to the Evaluation
     Time.

          For each evaluation, the Evaluator shall also determine and furnish to
     the Trustee and the Depositor the aggregate of (a) the value of all
     Securities on the basis of such evaluation and (b) on the basis of the
     information furnished to the Evaluator by the Trustee pursuant to Section
     3.02, the amount of cash then held in the Capital Account which was
     received by the Trustee after the Record Date preceding such determination
     less any amounts held in the Capital Account for distribution to
     Unitholders on a subsequent Distribution Date when a Record Date occurs
     four business days or less after such determination.  For the purposes of
     the foregoing, the Evaluator may obtain current prices for the Securities
     from investment dealers or brokers (including the Depositor) that
     customarily deal in similar securities.

          With respect to any Security not listed on a national or foreign
     exchange or The NASDAQ Stock Market, Inc., or, with respect to a Security
     so listed but in the unusual circumstance in which the Evaluator deems the
     closing sale price on the relevant

                                     -29-
<PAGE>

     exchange to be inappropriate as a basis for valuation, upon the Evaluator's
     request, the Depositor shall, from time to time, designate one or more
     evaluation services or other sources of information on which the Evaluator
     shall be authorized conclusively to rely in evaluating such Security. The
     Depositor shall also designate one or more banks (which may include the
     Trustee) or other source of information from which the Evaluator shall take
     foreign exchange rate quotations. The Evaluator shall have no liability for
     any errors in the information received from any source designated by the
     Depositor. The cost thereof shall be an expense reimbursable to the
     Evaluator from the Income and Capital Accounts.

          (b) Notwithstanding Section 4.01(a), except in those cases in which
     the Securities are listed on a national or foreign securities exchange or
     The NASDAQ Stock Market, Inc., and the closing sales prices are used and
     except for Trust Fund Evaluations required by Section 5.02 in determining
     Redemption Price, during the initial offering period, the evaluations of
     the Securities shall generally be made in the manner described in Section
     4.01(a) based on the closing ask prices of the Securities rather than the
     closing bid prices and on current offering side exchange rates.

     Section 4.02.  Certain Information to Be Made Available.  For the purpose
of permitting Unitholders to satisfy any reporting requirements of applicable
federal or state tax law, the Evaluator shall make available to the Trustee and
the Trustee shall transmit to any Unitholder upon request any evaluations
pursuant to Section 4.01 which concern the Trust Fund in which such Unitholder
holds Units.

     Section 4.03.  Compensation of the Evaluator.  As compensation for its
services hereunder, the Evaluator shall receive at the times specified in
Section 3.04 against a statement therefor submitted to the Trustee the amount
specified as compensation for the Evaluator in the Prospectus, calculated as
specified in Section 3.04, but, if the Depositor is acting as Evaluator, in no
event shall such compensation, when combined with all compensation received from
other series of the Fund or other unit investment trusts sponsored by the
Depositor or its affiliates for services as Evaluator, in any calendar year
exceed the aggregate cost to the Depositor of providing such services.  The rate
of such compensation may be increased from time to time, without the consent or
approval of any Unitholder or the Trustee, by amounts not exceeding the
proportionate increase, during the period from the date of the Trust Agreement
to the date of any such increase, in consumer prices as last published prior to
each such date under the classification "All Services Less Rent of Shelter" in
the Consumer Price Index For All Urban Consumers (CPI-U) U.S. City Average, not
seasonally adjusted, base 1982 - 84 = 100, published by the United States
Department of Labor.  In the event that such classification ceases to
incorporate a significant number of items, or if a substantial change is made in
the method of establishing such classification, then the classification shall be
adjusted in a fair and reasonable manner to the figure that would have resulted
had no substantial change occurred in the manner of computing such
classification.  In the event that such classification (or a successor or
substitute index) is not available, such governmental or other service or
publication as shall evaluate the information in substantially the same manner
as the aforesaid classification, shall be used in lieu thereof.  Such
compensation shall be charged by the Trustee, upon receipt of invoice therefor
from the Evaluator, against the Income and Capital Accounts as specified in

                                     -30-
<PAGE>

Section 3.04.  If the cash balances in the Income and Capital Accounts shall be
insufficient to provide for amounts payable pursuant to this Section 4.03, the
Trustee shall have the power to sell (1) Securities designated to be sold
pursuant to Section 5.02 hereof or (2) if no such Securities have been so
designated, such Securities as the Trustee may see fit to sell in its own
discretion, and to apply the proceeds of any such sale in payment of the amounts
payable pursuant to this Section 4.03.  Any moneys payable to the Evaluator
pursuant to this Section 4.03 shall be secured by a prior lien on the Trust Fund
except that such lien shall be junior and subordinate to any lien in favor of
the Trustee under the provisions of Section 8.08.

     Section 4.04.  Liability of the Evaluator.  The Trustee, the Depositor and
the Unitholders may rely on any evaluation furnished by the Evaluator and shall
have no responsibility for the accuracy thereof. The determinations made by the
Evaluator hereunder shall be made in good faith. The Evaluator shall be under no
liability to the Trustee, the Depositor or the Unitholders except for any
liability to which it would be subject by reason of willful misfeasance, bad
faith or negligence in the performance of its duties or by reason of its
reckless disregard of its obligations and duties hereunder.

     Section 4.05.  Resignation, Removal and Other Matters Relating to the
Evaluator.  (a) The Evaluator may resign and be discharged hereunder, by
executing an instrument in writing resigning as the Evaluator and filing the
same with the Depositor (if separate from the Evaluator) and the Trustee not
less than 60 days before the date specified in such instrument when, subject to
Section 4.05(c), such resignation is to take effect.  Upon receiving such notice
of resignation, the Depositor shall use its best efforts to appoint a successor
Evaluator having qualifications and at a rate of compensation satisfactory to
the Depositor.  Such appointment shall be made by written instrument executed by
the Depositor and the Trustee in duplicate, one copy of which shall be delivered
to the resigning Evaluator and one copy to the successor evaluator.  The
Depositor or the Trustee may remove the Evaluator at any time upon thirty days'
written notice and appoint a successor evaluator having qualifications and at a
rate of compensation satisfactory to the Depositor and the Trustee.  Such
appointment shall be made by written instrument executed by the Depositor and
the Trustee in duplicate, one copy of which shall be delivered to the Evaluator
so removed and one copy to the successor evaluator.  Notice of such resignation
or removal and appointment of a successor evaluator shall be mailed by the
Trustee to each Unitholder.

     (b) If the Evaluator resigns and no successor evaluator shall have been
appointed and have accepted appointment within 30 days after receipt of the
notice of resignation by the Depositor and the Trustee, the Evaluator may
forthwith apply to a court of competent jurisdiction for the appointment of a
successor evaluator.  Such court may thereupon, after such notice, if any, as it
may deem proper, appoint a successor evaluator.

     (c) Any successor evaluator appointed hereunder shall execute, acknowledge
and deliver to the Depositor and the Trustee an instrument accepting such
appointment hereunder, and such successor evaluator without any further act,
deed or conveyance shall become vested with all the rights, powers, duties and
obligations of its predecessor hereunder with like effect as if originally named
the Evaluator herein and shall be bound by all the terms and conditions of this
Agreement.  Any resignation or removal of the Evaluator and appointment of a
successor

                                     -31-
<PAGE>

evaluator pursuant to this Section 4.05 shall become effective upon such
acceptance of appointment.

     (d) Any corporation into which the Evaluator hereunder may be merged or
with which it may be consolidated, or any corporation resulting from any merger
or consolidation to which the Evaluator hereunder shall be a party, shall be the
successor evaluator under this Agreement without the execution or filing of any
paper, instrument or further act to be done on the part of the parties hereto,
anything herein, or in any agreement relating to such merger or consolidation,
by which the Evaluator may seek to retain certain powers, rights and privileges
theretofore obtaining for any period of time following such merger or
consolidation, to the contrary notwithstanding.

                                   Article V

                   Trust Fund Evaluation; Redemption of Units

     Section 5.01.  Trust Fund Evaluation.  As of the Evaluation Time next
following any tender by a Unitholder for redemption and on any other business
day desired by it or as may be required hereunder, the Trustee shall as to each
Trust Fund:

     Add

          (1) cash on hand in the Trust Fund (other than cash held especially
     for the purchase of Contract Securities) and moneys in the process of being
     collected from declared dividends,

          (2) the aggregate value of each issue of the Securities in the Trust
     Fund (including Contract Securities) as determined by the Evaluator
     pursuant to Section 4.01, and

          (3) all other assets of the Trust Fund;

     Deduct

          (1) amounts representing any applicable taxes, governmental charges
     or other charges pursuant to Section 3.03 payable out of the Trust Fund and
     for which no deductions shall have previously been made for the purpose of
     addition to the Reserve Account,

          (2) amounts representing estimated accrued fees and expenses of the
     Trust Fund including but not limited to unpaid accrued Creation and
     Development Fees, unpaid fees and expenses of the Trustee (including legal
     and auditing expenses), the Evaluator, the Depositor and counsel,

          (3) amounts representing unpaid accrued organization costs, and

                                     -32-
<PAGE>

          (4) cash allocated for distribution to Unitholders of the Trust Fund
     of record as of the business day prior to the evaluation then being made.

     The resulting figure is herein called a "Trust Fund Evaluation."

     Prior to the payment to the Depositor of its reimbursable organization
costs to be made at the earlier of six months after the Initial Date of Deposit
or the conclusion of the primary offering period in accordance with Section
10.02, for purposes of determining the Trust Fund Evaluation under this Section
5.01, the Trustee shall rely upon the amounts representing unpaid accrued
organization costs in the estimated amount per Unit set forth in the Prospectus
until such time as the Depositor notifies the Trustee in writing of a revised
estimated amount per Unit representing unpaid accrued organization costs.  Upon
receipt of such notice, the Trustee shall use this revised estimated amount per
Unit representing unpaid accrued organization costs in determining the Trust
Fund Evaluation but such revision of the estimated expenses shall not affect
calculations made prior thereto and no adjustment shall be made in respect
thereof.

     Amounts receivable by a Trust Fund in a foreign currency shall be reported
to the Evaluator who shall convert the same to U.S. dollars based on current
exchange rates, in the same manner as provided in Section 4.01, for the
conversion of the valuation of foreign Securities, and the Evaluator shall
report such conversion with each Evaluation made pursuant to Section 4.01.

     Section 5.02.  Redemption of Units; Sale of Securities.  (a) Any
Unitholder may cause any of his Units to be redeemed by the Trustee, subject to
the terms of this Section 5.02, by making a written request to the Trustee at
its principal trust office, and, in the case of Units evidenced by a
Certificate, by tendering such Certificate to the Trustee at such office,
properly endorsed or accompanied by a written instrument or instruments of
transfer in form satisfactory to the Trustee.  Unitholders must sign such
written request, and such Certificate or transfer instrument, exactly as their
name appears on the records of the Trustee and on any Certificate representing
the Units to be redeemed.  Such signature must be guaranteed by a participant in
the Securities Transfer Agents Medallion Program ("STAMP") or such other
signature guarantee program in addition to, or in substitution for, STAMP, as
may be accepted by the Trustee.  Such redemption shall be made by the Trustee on
the third business day following the day on which request for redemption is
received by the Trustee, (such date being herein called the "Redemption Date").
Subject to payment by such Unitholder of any tax or other governmental charges
which may be imposed thereon and subject to payments in the form of In Kind
Distributions (as defined below), such redemption is to be made by payment on
the Redemption Date of cash equal to the Unit Value (determined on the basis of
the Trust Fund Evaluation made in accordance with Section 5.01) multiplied by
the number of Units being redeemed (herein called the "Redemption Price").  The
portion of the Redemption Price which represents dividends shall be withdrawn
from the Income Account of the affected Trust Fund to the extent available.  The
balance paid on any redemption shall be withdrawn from the Capital Account of
the affected Trust Fund to the extent that funds are available for such purpose.
If such available balance shall be insufficient, the Trustee shall sell from
such Trust Fund such Securities from among those designated for such purpose by
the Depositor as the Trustee in its discretion, shall deem advisable or
necessary.  In the event that funds are withdrawn from the Capital Account or
Securities are sold for payment

                                     -33-
<PAGE>

of any portion of the Redemption Price representing declared but unpaid
dividends, the Capital Account shall be reimbursed when sufficient funds are
next available in the Income Account for such funds so applied.

     (b) The Trustee may in its discretion, and shall when so directed by the
Depositor in writing, suspend the right of redemption or postpone the date of
payment of the Redemption Price for more than three business days following the
day on which tender for redemption is made (1) for any period during which the
New York Stock Exchange, Inc. is closed other than customary weekend and holiday
closings; (2) for any period during which (i) trading on the New York Stock
Exchange, Inc. is restricted or (ii) an emergency exists as a result of which
disposal by the Trust Fund of the Securities is not reasonably practicable or it
is not reasonably practicable to fairly determine in accordance herewith the
value of the Securities for the purposes of any Trust Fund Evaluation; or (3)
for such other period as the Securities and Exchange Commission may by order
permit.

     (c) No later than the close of business on the day of tender of any Unit
for redemption by a Unitholder other than the Depositor, the Trustee shall
notify the Depositor of such tender.  The Depositor shall have the right to
purchase such Units by notifying the Trustee of its election to make such
purchase as soon as practicable thereafter but in no event subsequent to the
close of business on the second business day after the day on which such Units
were tendered for redemption.  Such purchase shall be made by payment for such
Units by the Depositor to the Unitholder not later than the close of business on
the Redemption Date of any amount not less than the Redemption Price which would
otherwise be payable by the Trustee to such Unitholder.  Any Unit so purchased
by the Depositor may at the option of the Depositor be tendered to the Trustee
for redemption in the manner provided in the first paragraph of this Section
5.02.

     (d) Notwithstanding anything to the contrary in this Section 5.02, if
offered by the terms of the Prospectus, any Unitholder may, if such Unitholder
tenders at least that number of Units set forth in the Prospectus for redemption
and makes such tender on or prior to the date provided in the Prospectus,
request at the time of tender to receive from the Trustee in lieu of cash such
Unitholder's pro rata share of each Security then held by the Trust Fund.  Such
tendering Unitholder will receive his pro rata number of whole shares of each of
the Securities comprising the portfolio of the Trust Fund and cash from the
Capital Account equal to the value of the fractional shares to which such
tendering Unitholder is entitled.  Such pro rata share of each Security and the
related cash equal to the value of the fractional shares to which such tendering
Unitholder is entitled is referred to herein as an "In Kind Distribution."  An
In Kind Distribution will be made by the Trustee through the distribution of
each of the Securities in book-entry form to the account of the Unitholder's
bank or broker-dealer at Depository Trust Company.  If funds in the Capital
Account are insufficient to cover the required cash distribution to the
tendering Unitholder, the Trustee may sell Securities according to the criteria
discussed above.

     (e) The Depositor shall deliver a current list of Securities in each Trust
Fund to be sold for the purpose of redemption of Units tendered for redemption
and for payment of expenses hereunder.  If at any such time the Depositor shall
for any reason fail to deliver such a list, the Trustee, in its sole discretion,
may designate a current list of Securities in each Trust Fund for

                                     -34-
<PAGE>

such purposes. The net proceeds of any sale of Securities shall be credited to
the Capital Account of such Trust Fund.

     (f) Except as provided in Article VII and Article VIII, neither the
Depositor nor the Trustee shall be liable or responsible in any way for
depreciation or loss incurred by reason of any sale or designation of Securities
made pursuant to this Section 5.02.

     (g) If applicable, Any Certificates evidencing Units redeemed pursuant to
this Section 5.02 shall be cancelled by the Trustee and the Unit or Units
evidenced by such Certificates shall be extinguished by such redemptions.

     (h) Sales of foreign securities shall be made in such manner and at such
price as the Depositor, or its delegate, shall direct, and the Trustee shall not
be liable or responsible for depreciation or loss incurred by reason of any sale
made pursuant to such direction.

     (i) If a Trust Fund has elected to be taxed as a "regulated investment
company" and such Trust Fund's portfolio is based upon an index, and if
Securities in the Trust Fund are sold for the payment of the Redemption Price
and there are excess proceeds remaining after meeting redemption requests, the
Depositor or its designee may, but is not obligated to, direct the investment of
such excess proceeds into any Securities included in the applicable index.

     Section 5.03.  Rollover of Units.  (a) If the Depositor shall offer a
subsequent series of the Nuveen Unit Trust (the "New Series"), the Trustee
shall, at the Depositor's direction and at the Depositor's sole cost and
expense, include in the notice sent to Unitholders a form of election whereby
Unitholders, whose redemption distribution would be in an amount sufficient to
purchase at least one Unit of the New Series, may elect to have their Units(s)
redeemed in kind in the manner provided in Section 5.02, the Securities included
in the redemption distribution sold, and the cash proceeds applied by the
Distribution Agent to purchase Units of the New Series, all as hereinafter
provided.  The Trustee shall honor properly completed election forms returned to
the Trustee, accompanied by any Certificate evidencing Units tendered for
redemption or a properly completed redemption request with respect to
uncertificated Units, by its close of business on the Rollover Notification
Date.  The notice and form of election to be sent to Unitholders in respect of
any redemption and purchase of Units of a New Series as provided in this section
shall be in such form and shall be sent at such time or times as the Depositor
shall direct the Trustee in writing and the Trustee shall have no responsibility
therefor.  The Distribution Agent acts solely as disbursing agent in connection
with purchases of Units pursuant to this Section and nothing herein shall result
in the Distribution Agent being deemed a broker in such transactions.

     All Units so tendered by a Unitholder (a "Rollover Unitholder") shall be
redeemed and cancelled on such date during the Special Redemption and
Liquidation Period as the Depositor shall determine and notify the Trustee
thereof.  Subject to payment by such Rollover Unitholder of any tax or other
governmental charges which may be imposed thereon, such redemption is to be made
in kind pursuant to Section 5.02 by distribution of cash and/or Securities to
the Distribution Agent based on the net asset value on the date the Units are
redeemed and cancelled multiplied by the number of Units being redeemed (herein
called the "Rollover Distribution").

                                     -35-
<PAGE>

     All Securities included in a Unitholder's Rollover Distribution shall be
sold by the Distribution Agent during the Special Redemption and Liquidation
Period pursuant to the Depositor's direction, and the Distribution Agent shall,
when directed by the Depositor, employ the Depositor or one of its affiliates as
broker in connection with such sales.  For such brokerage services, the
Depositor or such affiliate shall be entitled to compensation at its customary
rates, provided however, that its compensation shall not exceed the amount
authorized by applicable securities laws and regulations.  The Depositor or such
affiliate shall direct that sales be made in accordance with the guidelines set
forth in the related Prospectus.  The Distribution Agent shall have no
responsibility for any loss or depreciation incurred by reason of any sale made
pursuant to this Section.

     Upon each trade date for sales of Securities included in the Rollover
Unitholder's Rollover Distribution, the Distribution Agent shall, as agent for
such Rollover Unitholder, enter into a contract with the Depositor to purchase
from the Depositor Units of the New Series (if any), at the Depositor's public
offering price for such Units on such day, and at such reduced sales charge as
shall be described in the Prospectus for the New Series.  Such contract shall
provide for purchase of the maximum number of Units of the New Series whose
purchase price is equal to or less than the cash proceeds held by the
Distribution Agent for the Unitholder on such day (including therein the
proceeds anticipated to be received in respect of Securities traded on such day
net of all brokerage fees, governmental charges and any other expenses incurred
in connection with such sale), to the extent Units are available for purchase
from the Depositor.  In the event a sale of Securities included in the Rollover
Unitholder's redemption distribution shall not be consummated in accordance with
its terms, the Distribution Agent shall apply the cash proceeds held for such
Unitholder as of the settlement date for the purchase of Units of the New Series
to purchase the maximum number of units which such cash balance will permit, and
the Depositor agrees that the settlement date for Units whose purchase was not
consummated as a result of insufficient funds will be extended until cash
proceeds from the Rollover Distribution are available in a sufficient amount to
settle such purchase.  If the Unitholder's Rollover Distribution will produce
insufficient cash proceeds to purchase all of the Units of the New Series
contracted for, the Depositor agrees that the contract shall be rescinded with
respect to the Units as to which there was a cash shortfall without any
liability to the Rollover Unitholder or the Distribution Agent.  Any cash
balance remaining after such purchase shall be distributed within a reasonable
time to the Rollover Unitholder by check mailed to the address of such
Unitholder on the registration books of the Trustee.  Any cash held by the
Distribution Agent shall be held in a non-interest bearing account which will be
of benefit to the Distribution Agent.  Except as provided in Article VIII,
neither the Trustee nor the Distribution Agent shall have any responsibility or
liability for loss or depreciation resulting from any reinvestment made in
accordance with this paragraph, or for any failure to make such reinvestment in
the event the Depositor does not make Units available for purchase.

     (b) Notwithstanding the foregoing, the Depositor may, in their discretion
at any time, decide not to offer Trust Series in the future, and if so, this
Section 5.03 concerning the Rollover of Units shall be inoperative.

     (c) The Distribution Agent shall receive no fees for performing its duties
hereunder.  The Distribution Agent shall, however, be entitled to receive
reimbursement from the Trust Fund

                                     -36-
<PAGE>

for any and all expenses and disbursements to the same extent as the Trustee is
permitted reimbursement hereunder.

                                   Article VI

        Issuance, Transfer, Interchange and Replacement of Certificates

     Section 6.01.  Issuance of Certificates.  Unless otherwise provided in the
Prospectus, Certificates representing Units held by a Unitholder will be issued
unless a Unitholder requests to hold Units in book entry form. Certificates that
have been issued may be returned to the Trustee at any time and cancelled,
without affecting the Unitholder's interest in the Trust Fund, when accompanied
by proper written instructions from the Unitholder.

     Section 6.02.  Transfer of Units; Interchange of Certificates.  A
Unitholder may transfer any of his Units by making a written request to the
Trustee at its unit investment trust office and, in the case of Units evidenced
by a Certificate, by presenting and surrendering such Certificate at such office
properly endorsed or accompanied by a written instrument or instruments of
transfer in form satisfactory to the Trustee.  Unitholders must sign such
written request, and such Certificate of transfer instrument, exactly as their
name appears on the records of the Trustee and on any Certificate representing
the Units to be transferred.  Such signature must be guaranteed by a participant
in the Securities Transfer Agents Medallion Program ("STAMP") or such other
signature guarantee program in addition to, or in substitution for, STAMP, as
may be accepted by the Trustee.  Such transfer shall thereupon be made on the
records of the Trustee and, if appropriate, a new registered Certificate or
Certificates for the same number of Units of the same Trust Fund shall be issued
in exchange and substitution therefor.  Certificates issued pursuant to this
Agreement are interchangeable for one or more other Certificates of the same
Trust Fund in an equal aggregate number of Units and all Certificates issued
shall be issued in denominations of one Unit or any whole multiple thereof as
may be requested by the Unitholder.  The Trustee may deem and treat the person
in whose name any Unit or Certificate shall be registered upon the books of the
Trustee as the owner of such Unit or Certificate for all purposes hereunder and
the Trustee shall not be affected by any notice to the contrary.  The transfer
books maintained by the Trustee for each Trust Fund for the purpose of this
Section 6.02 shall be closed for an individual Trust Fund as such Trust Fund is
terminated pursuant to Article IX hereof.

     A sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any such transfer or interchange shall be paid to the
Trustee.  A Unitholder may be required to pay $2 (or such other amount as may be
specified by the Trustee and approved by the Depositor) for each new Certificate
issued on any such transfer or interchange.

     All Certificates cancelled pursuant to this Agreement, other than those
endorsed for transfer, may be cremated or otherwise destroyed by the Trustee.

     Section 6.03.  Replacement of Certificates.  In case any Certificate shall
become mutilated or be destroyed, stolen or lost, the Trustee shall execute and
deliver a new Certificate in exchange and substitution therefor upon the
Unitholder's furnishing the Trustee with proper

                                     -37-
<PAGE>

identification and satisfactory indemnity, complying with such other reasonable
regulations and conditions as the Trustee may prescribe and paying such expenses
as the Trustee may incur, provided, however, that if the particular Trust Fund
has terminated or is in the process of termination, the Trustee, in lieu of
issuing such new Certificate, may, upon the terms and conditions set forth
herein, make the distributions set forth in Section 9.01 hereof. Any mutilated
Certificate shall be duly surrendered and cancelled before any duplicate
Certificate shall be issued in exchange and substitution therefor. Any duplicate
Certificate issued pursuant to this Section 6.03 shall constitute complete and
indefeasible evidence of ownership in the Trust Fund, as if originally issued,
whether or not the lost, stolen or destroyed Certificate shall be found at any
time. Upon issuance of any duplicate Certificate pursuant to this Section 6.03,
the Certificate claimed to have been lost, stolen or destroyed shall become null
and void and of no effect, and any bona fide purchaser thereof shall have only
such rights as are afforded under Article 8 of the Uniform Commercial Code to a
holder presenting a Certificate for transfer in the case of an over issue.

     Section 6.04.  Form of Certificate.  Each Certificate shall be in fully
registered form, shall be numbered serially for identification, shall be
executed in facsimile by the original Depositor of the Trust Fund in question
and manually by an authorized signatory of the Trustee, shall be dated the date
of execution and delivery by the Trustee and shall represent a fractional
undivided interest in the specified Trust Fund, the numerator of which fraction
shall be the number of Units set forth on the face of such Certificate and the
denominator of which shall be the total number of Units of undivided interest of
such Trust Fund outstanding at any such time.

                                  Article VII

                                   Depositor

     Section 7.01.  Certain Matters Regarding Succession.  The covenants,
provisions and agreements herein contained shall in every case be binding upon
any successor to the business of any Depositor. In the event of an assignment by
any Depositor to a successor corporation or partnership as permitted by the next
following sentence, such Depositor and, if such Depositor is a partnership, its
partners shall be relieved of all further liability under this Agreement. Any
Depositor may transfer all or substantially all of its assets to a corporation,
company or partnership which carries on the business of such Depositor, if at
the time of such transfer such successor duly assumes all the obligations of
such Depositor under this Agreement.

     Section 7.02.  Liability of Depositor and Indemnification.  (a) The
Depositor shall not be under any liability to any Trust Fund or the Unitholders
for any action taken or for refraining from the taking of any action in good
faith pursuant to this Agreement, or for errors in judgment or for depreciation
or loss incurred by reason of the purchase or sale of any Securities, provided,
however, that this provision shall not protect the Depositor against any
liability to which it would otherwise be subject by reason of willful
misfeasance, bad faith or negligence in the performance of its duties or by
reason of its reckless disregard of its obligations and duties hereunder.  The
Depositor may rely in good faith on any paper, order, notice, list, affidavit,
receipt, evaluation, opinion, endorsement, assignment, draft or any other
document of any kind prima facie properly

                                     -38-
<PAGE>

executed and submitted to it by the Trustee, the Trustee's counsel, the
Evaluator or any other person for any matters arising hereunder. The Depositor
shall in no event be deemed to have assumed or incurred any liability, duty or
obligation to any Unitholder, the Evaluator or the Trustee other than as
expressly provided for herein.

     (b) Each Trust Fund shall pay and hold the Depositor harmless from and
against any loss, liability or expense incurred in acting as Depositor of such
Trust Fund other than by reason of willful misfeasance, bad faith or gross
negligence in the performance of its duties or by reason of its reckless
disregard of its obligations and duties hereunder.  The Depositor shall not be
under any obligation to appear in, prosecute or defend any legal action which in
its opinion may 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 in respect of this Agreement and the rights and duties of
the parties hereto and the interests of the Unitholders hereunder and, in such
event, the legal expenses and costs of any such action and any liability
resulting therefrom shall be expenses, costs and liabilities of the Trust Fund
concerned and shall be paid directly by the Trustee out of the Income and
Capital Accounts of such Trust Fund.

     (c) None of the provisions of this Agreement shall be deemed to protect or
purport to protect the Depositor against any liability to the Trust Fund or to
the Unitholders to which the Depositor would otherwise be subject by reason of
willful misfeasance, bad faith or negligence in the performance of its duties,
or by reason of the Depositor's reckless disregard of its obligations and duties
under this Agreement.

     (d) The Depositor may employ agents in connection with its duties under
Sections 3.11 and 3.13 hereof and shall not be answerable for the default or
misconduct of such agents if they shall have been selected with reasonable care.
The fees of such agents shall be reimbursable to the Depositor from the Trust
Fund, provided, however, that the amount of such reimbursement in any year (1)
shall reduce the amount payable to the Depositor for such year with respect to
the service in question and shall not exceed the maximum amount payable to the
Depositor for such service for such year and (2) if such agent is an affiliate
of the Depositor, the amount of the reimbursement, when combined with (i) all
compensation received by such agent from other series of the Fund or other unit
investment trusts sponsored by the Depositor or its affiliates and (ii) the
amount payable to the Depositor from the Trust Fund and from other series of the
Fund or other unit investment trusts sponsored by the Depositor or its
affiliates in respect of the service in question, shall not exceed the aggregate
cost of such agent and the Depositor of providing such service.  The Trustee
shall pay such reimbursement against the Depositor's invoice therefor upon which
the Trustee may rely as the Depositor's certification that the amount claimed
complies with the provisions of this paragraph.

                                  Article VIII

                                    Trustee

     Section 8.01.  General Matters Relating to the Trustee.  (a) All moneys
deposited with or received by the Trustee hereunder shall be held by it without
interest in trust as part of the

                                     -39-
<PAGE>

appropriate Trust Fund or Reserve Account until required to be disbursed in
accordance with the provisions of this Agreement and such moneys will be
segregated in such manner as shall constitute the segregation and holding
thereof in trust within the meaning of the Investment Company Act of 1940.

     (b) The Trustee shall be under no liability for any action taken in good
faith on any evaluation, paper, order, list, demand, request, consent,
affidavit, notice, opinion, direction, endorsement, assignment, resolution,
draft or other document whether or not of the same kind, prima facie properly
executed, or the disposition of moneys or Securities pursuant to this Agreement;
provided, however, that this provision shall not protect the Trustee against any
liability to which it would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence in the performance of its duties or
by reason of its reckless disregard of its obligations and duties hereunder, and
the Trustee may construe any of the provisions of this Agreement insofar as the
same may appear to be ambiguous or inconsistent with any other provisions
hereof, and any construction of any such provisions hereof by the Trustee in
good faith shall be binding upon the parties hereto and the Unitholders.

     (c) The Trustee shall not be responsible for or in respect of the recitals
herein, the validity or sufficiency of this Agreement or for the due execution
hereof by the Depositor, or for the form, character, genuineness, sufficiency,
value or validity of any Securities or for or in respect of the validity or
sufficiency of any Certificates (except for the due execution thereof by the
Trustee) or for the due execution thereof by the Depositor and the Trustee shall
in no event assume or incur any liability, duty or obligation to any Unitholder
or to the Depositor or Evaluator, other than as expressly provided for herein.
The Trustee shall not be responsible for or in respect of the validity of any
signature by or on behalf of the Depositor.

     (d) The Trustee shall not be under any obligation to appear in, prosecute
or defend any action which in its opinion may involve it in expense or liability
unless it shall be furnished with such reasonable security and indemnity against
such expense or liability as it may be required, and any pecuniary cost of the
Trustee from such actions shall be deductible ratably from and a ratable charge
against the Trust Funds concerned.  The Trustee shall in its discretion
undertake such action as it may deem necessary at any and all times to protect
the Trust Funds and the rights and interests of the Unitholders pursuant to the
terms of this Agreement, provided, however, that the expenses and costs of such
actions, undertakings or proceedings shall be reimbursable to the Trustee
ratably from the Trust Funds concerned.

     (e) (1) Subject to the provisions of subparagraphs (2) and (3) of this
paragraph, the Trustee may employ agents, sub-custodians, attorneys, accountants
and auditors and shall not be answerable for the default or misconduct of any
such agents, sub-custodians, attorneys, accountants or auditors if such agents,
sub-custodians, attorneys, accountants or auditors shall have been selected with
reasonable care.  The Trustee shall be fully protected in respect of any action
under this Agreement taken or suffered in good faith by the Trustee in
accordance with the opinion of counsel, which may be counsel to the Depositor
acceptable to the Trustee, provided, however, that this disclaimer of liability
shall not (i) excuse the Trustee from the responsibilities specified in
subparagraph II below or (ii) limit the obligation of the Trustee to indemnify
the Trust Fund under subparagraph III below.  The fees and expenses charged by
such agents,

                                     -40-
<PAGE>

sub-custodians, attorneys, accountants or auditors shall constitute an expense
of the Trust Fund reimbursable from the Income and Capital Accounts of the
affected Trust Fund as set forth in section 8.05 and 3.04 hereof.

     (2) The Trustee may place and maintain in the care of an eligible foreign
custodian (which is employed by the Trustee as a sub-custodian as contemplated
by subparagraph (I) of this paragraph (e) and which may be an affiliate or
subsidiary of the Trustee or any other entity in which the Trustee may have an
ownership interest) a Trust Fund's foreign securities, cash and cash equivalents
in amounts reasonably necessary to effect the Trust Fund's foreign securities
transactions, provided that the Trustee hereby agrees to perform all the duties
assigned by rule 17f-5 as now in effect or as it may be amended in the future,
to the boards of directors of management investment companies.  The Trustee's
duties under the preceding sentence will not be delegated.

     As used in this subparagraph (2),

          (i) "foreign securities" include:  securities issued and sold
     primarily outside the United States by a foreign government, a national of
     any foreign country or a corporation or other organization incorporated or
     organized under the laws of any foreign country and securities issued or
     guaranteed by the government of the United States or by any state or any
     political subdivision thereof or by any agency thereof or by any entity
     organized under the laws of the United States or of any state thereof which
     have been issued and sold primarily outside the United States.

          (ii) "eligible foreign custodian" means (x) the following securities
     depositories and clearing agencies which operate transnational systems for
     the central handling of securities or equivalent book entries which, by
     appropriate exemptive order issued by the Securities and Exchange
     Commission, have been qualified as eligible foreign custodians for the
     Trust Funds but only for so long as such exemptive order continues in
     effect:  the Euroclear System ("Euroclear") and Cedel Bank S.A. ("CEDEL"),
     or their successors.

          (y) Any other entity that shall have been qualified as an eligible
     foreign custodian for the foreign securities of the Trust Funds by the
     Securities and Exchange Commission by exemptive order, rule or other
     appropriate action, commencing on such date as it shall have been so
     qualified but only for so long as such exemptive order, rule or other
     appropriate action continues in effect.

     (3) The Trustee will indemnify and hold the Trust Funds harmless from and
against any loss occurring as a result of an eligible foreign custodian's
willful misfeasance, reckless disregard, bad faith, or gross negligence in
performing custodial duties.

     (f) If at any time the Depositor shall fail to undertake or perform any of
the duties which by the terms of this Agreement are affirmatively required by it
to be undertaken or performed, or the Depositor shall be incapable of acting, or
shall be adjudged a bankrupt or insolvent, or a receiver of the Depositor or of
its property shall be appointed, or any public

                                     -41-
<PAGE>

officer shall take charge or control of the Depositor or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, then in
any such case, the Trustee may do any one or more of the following: (1) appoint
a successor Depositor who shall act hereunder in all respects in place of such
Depositor and which may be compensated, at rates deemed by the Trustee to be
reasonable under the circumstances, by deduction ratably from the Income Account
or, to the extent funds are not available in such Account, from the Capital
Account of the Trust Funds but no such deduction shall be made exceeding such
reasonable amount as the Securities and Exchange Commission may prescribe in
accordance with Section 26(a)(2)(C) of the Investment Company Act of 1940; (2)
continue to act as Trustee hereunder without terminating this Agreement; or (3)
terminate this Agreement and the trust created hereby and liquidate the Trust
Funds in the manner provided in Section 9.01.

     (g) (1) The Trustee may in its discretion, and shall if so directed by the
Depositor, terminate this Agreement and any Trust Fund created hereby (but only
insofar as the Agreement relates to such Trust Fund) and liquidate such Trust
Fund, all in the manner provided in Section 9.01 if the value of such Trust Fund
as shown by any Trust Fund Evaluation shall be less than the liquidation amount
specified in the Prospectus; and (2) the Trustee shall terminate this Agreement
and any Trust Fund created hereby (but only insofar as the Agreement relates to
such Trust Fund) and liquidate such Trust Fund all in the manner provided in
Section 9.01 if by reason of the aggregate redemption of Units not theretofore
sold by the Depositor and/or one or more of the underwriters the net worth of
such Trust Fund is reduced to less than 40% of the aggregate original value of
the Securities initially deposited therein.

     (h) In no event shall the Trustee be personally liable for any taxes or
other governmental charges imposed upon or in respect of the Securities or upon
any dividends or interest thereon.  The Trustee shall be reimbursed and
indemnified out of the Income and Capital Accounts of the appropriate Trust Fund
for all such taxes and charges, for any tax or charge imposed against the
Trustee as Trustee of such Trust Fund and for any expenses, including counsel
fees, which the Trustee may sustain or incur with respect to such taxes or
charges.

     (i) Notwithstanding any provisions of this Agreement to the contrary, no
payment to a Depositor or to any principal underwriter (as defined in the
Investment Company Act of 1940) for each Trust Fund or to any affiliated person
(as so defined) or agent of a Depositor or such underwriter shall be allowed the
Trustee as an expense except (a) for payment of such reasonable amounts as the
Securities and Exchange Commission may prescribe as compensation for performing
bookkeeping and other administrative services of a character normally performed
by the Trustee and (b) such other amounts permitted under the Investment Company
Act of 1940.

     (j) The Trustee in its individual or any other capacity may become an
owner or pledgee of, or be an underwriter or dealer in respect of, obligations
issued by the same issuer (or an affiliate of such issuer) or any Securities at
any time held as part of the Trust Fund and may deal in any manner with the same
or with the issuer (or an affiliate of the issuer) with the rights and powers as
if it were not the Trustee hereunder.

     (k) The Trust Fund may include a letter or letters of credit for the
purchase of Securities or Contract Securities issued by the Trustee in its
individual capacity for the account of the

                                     -42-
<PAGE>

Depositor and the Trustee may otherwise deal with the Depositor and the Trust
Fund within the same rights and powers as if it were not the Trustee hereunder.

     (l) The Trustee except by reason of its own negligence or willful
misconduct shall not be liable for any action taken or suffered to be taken 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 Agreement.

     (m) The Bank of New York, or an affiliate, may, when instructed by the
Depositor pursuant to Section 3.16, enter into foreign exchange transactions
with the Trust Fund, with the same rights and powers as if The Bank of New York
were not the Trustee hereunder.

     The provisions of this section and the indemnification provided the Trustee
under Section 8.05 and collateral security provided the Trustee under Section
8.08 shall apply as fully to the Trustee in its capacity as Evaluator, Program
Agent and Distribution Agent.

     Section 8.02.  Books, Records and Reports.  The Trustee shall keep proper
books of record and account of all the transactions of each Trust Fund under
this Agreement at its unit investment trust office including a record of the
name and address of, and the Certificates issued by each Trust Fund and held by,
every Unitholder, and such books and records of each Trust Fund shall be open to
inspection by any Unitholder of such Trust Fund at all reasonable times during
the usual business hours.

     Unless the Depositor determines that such an audit is not required, the
account of each Trust Fund shall be audited not less than annually by
independent public accountants designated from time to time by the Depositor and
reports of such accountants shall be furnished by the Trustee, upon request, to
Unitholders.  The Trustee, however, in connection with any such audits shall not
be obligated to use Trust Fund assets to pay for such audits in excess of the
amounts indicated in the Prospectus relating to such Trust Fund.

     To the extent permitted under the Investment Company Act of 1940 as
evidenced by an opinion of independent counsel to the Depositor satisfactory to
the Trustee or "no-action" letters issued by the staff of the Securities and
Exchange Commission, the Trustee shall pay, or reimburse to the Depositor or
others, the costs of the preparation of documents and information with respect
to a Trust Fund required by law or regulation in connection with the maintenance
of a secondary market in Units of such Trust Fund.  Such costs may include, but
are not limited to, accounting and legal fees, blue sky registration and filing
fees, printing expenses and other reasonable expenses related to documents
required under federal and state securities laws.  Such costs shall be a Trust
Fund expense and the Trustee shall not be obligated to advance any of its own
funds to make such payments.

     Section 8.03.  Reports to Securities and Exchange Commission and Others.
Upon the request of the Depositor, the Trustee shall make such annual or other
reports as may from time to time be required under any applicable state or
federal statute or rule or regulation thereunder.

     Section 8.04.  Agreement and List of Securities on File.  The Trustee shall
keep a certified copy or duplicate original of this Agreement on file at its
unit investment trust office available

                                     -43-
<PAGE>

for inspection by any Unitholder at all reasonable times during its usual
business hours, and the Trustee shall keep and so make available for inspection
a current list of the Securities in each Trust Fund.

     Section 8.05. Compensation of Trustee. The Trustee shall receive at the
times and in the manner set forth in Section 3.04 as compensation for performing
the usual, ordinary, normal and recurring services under this Agreement during
the preceding month an amount equal to the amount specified as compensation for
the Trustee in the Prospectus. Such fee shall be calculated as specified in
Section 3.04. The Trustee may, without the consent or approval of any Unitholder
or the Depositor, periodically adjust the compensation provided for pursuant to
this paragraph (a) in response to fluctuations in short-term interest rates and
average cash balances of the Trust Fund accounts (reflecting the cost to the
Trustee of advancing funds to a Trust Fund and changes in anticipated earnings
on cash balances), and (b) to adjust such portion of its fee as is not computed
by reference to the cash balance in the Trust Fund accounts by amounts not
exceeding the proportionate increase, during the period from the date of such
Trust Agreement to the date of any such increase, in consumer prices as last
published prior to each such date under the classification "All Services Less
Rent of Shelter" in the Consumer Price Index For All Urban Consumers (CPI-U)
U.S. City Average, not seasonally adjusted, base 1982 - 84 = 100, published by
the United States Department of Labor. In the event that such classification
ceases to incorporate a significant number of items, or if a substantial change
is made in the method of establishing such classification, then the
classification shall be adjusted in a fair and reasonable manner to the figure
that would have resulted had no substantial change occurred in the manner of
computing such classification. In the event that such classification (or a
successor or substitute index) is not available, such governmental or other
service or publication as shall evaluate the information in substantially the
same manner as the aforesaid classification, shall be used in lieu thereof. The
Trustee shall also receive, at the times and in the manner set forth in Section
3.04, reimbursement for any and all expenses, disbursements and advances
incurred hereunder including legal and auditing expenses and additional
compensation for any extraordinary services performed hereunder, which
extraordinary services shall include, but not be limited to, all costs and
expenses incurred by the Trustee in making any annual or other reports pursuant
to Section 8.03, or in making any distribution of cash attributable to failed
contracts covering Contract Securities in accordance with Section 3.04;
provided, however, that the amount of any such charge which has not been finally
determined as of any Distribution Date may be estimated and any necessary
adjustments shall be made in any succeeding period.

     The Trustee shall be indemnified ratably from the Trust Funds and held
harmless against any loss, liability or expense incurred without gross
negligence, bad faith, willful misconduct or reckless disregard of its duties on
the part of the Trustee arising out of or in connection with the acceptance or
administration of this trust, including the costs and expenses of defending
itself against any claim or liability in the premises.

     The Trustee's normal and extraordinary compensation and reimbursement of
the above-mentioned expenses and losses shall be charged by the Trustee against
the Income and Capital Accounts of the appropriate Trust Funds in accordance
with Section 3.04.  If the balances in the Income and Capital Accounts shall be
insufficient to provide for amounts payable pursuant to this Section 8.05, the
Trustee shall have the power to sell Securities in the manner provided in

                                     -44-
<PAGE>

Section 5.02 hereof.  The Trustee shall not be liable or responsible in any way
for depreciation or loss incurred by reason of any sale of Securities made
pursuant to this Section 8.05.

     Section 8.06.  Resignation, Discharge or Removal of the Trustee;
Successors.  (a) The Trustee may resign and be discharged of the trust created
by this Agreement by executing an instrument in writing resigning as Trustee of
such trust, filing the same with the Depositor and mailing a copy of a notice of
resignation to all Unitholders then of record, not less than sixty days before
the date specified in such instrument when, subject to Section 8.06(c), such
resignation is to take effect. Upon receiving such notice of resignation, the
Depositor shall use its best efforts promptly to appoint a successor trustee in
the manner and meeting the qualifications hereinafter provided, by written
instrument or instruments delivered to the resigning Trustee and the successor
trustee. In case at any time the Trustee shall not meet the requirements set
forth in Section 8.06 hereof, or shall become incapable of acting, or if a court
having jurisdiction in the premises shall enter a decree or order for relief in
respect of the Trustee in an involuntary case, or the Trustee shall commence a
voluntary case, under any applicable bankruptcy, insolvency or other similar law
now or hereafter in effect, or any receiver, liquidator, assignee, custodian,
trustee, sequestrator (or similar official) for the Trustee or for any
substantial part of its property shall be appointed, or the Trustee shall
generally fail to pay its debts as they become due, the Depositor, upon 60 days'
prior written notice, may remove the Trustee and appoint a successor trustee
having qualifications and at a rate of compensation satisfactory to the
Depositor by written instrument, in duplicate, one copy of which shall be
delivered to the Trustee so removed and one copy to the successor trustee. The
Depositor may also remove the Trustee at any time with or without cause and
appoint a successor Trustee by written instrument or instruments delivered not
less than sixty days prior to the effective date of such removal and appointment
to the Trustee so removed and to the successor Trustee. Notice of such
appointment of a successor trustee shall be mailed promptly after acceptance of
such appointment by the successor trustee to each Unitholder then of record.

     (b) In case at any time the Trustee shall resign and no successor trustee
shall have been appointed within thirty days after notice of resignation has
been received by the Depositor, the retiring Trustee may forthwith apply to a
court of competent jurisdiction for the appointment of a successor trustee.
Such court may thereupon, after such notice, if any, as it may deem proper and
prescribe, appoint a successor trustee.

     (c) Any successor trustee appointed hereunder shall execute and
acknowledge to the Depositor and the retiring Trustee an instrument accepting
such appointment hereunder, and such successor trustee without any further act,
deed or conveyance shall become vested with all rights, powers, duties and
obligations of its predecessor hereunder with like effect as if originally named
a Trustee herein and shall be bound by all the terms and conditions of this
Agreement provided, however, that no successor trustee shall be under any
liability hereunder for occurrences or omissions prior to the execution of such
instrument.  Upon the request of such successor trustee, the retiring Trustee
shall, upon payment of all amounts due the retiring Trustee, execute and deliver
an instrument acknowledged by it transferring to such successor trustee all the
rights and powers of the retiring Trustee; and the retiring Trustee shall
transfer, deliver and pay over to the successor trustee all Securities and
moneys at the time held by it hereunder, if any, together with all necessary
instruments of transfer and assignment or other documents properly executed

                                     -45-
<PAGE>

necessary to effect such transfer and such of the records or copies thereof
maintained by the retiring Trustee in the administration hereof as may be
requested by the successor trustee and shall thereupon be discharged from all
duties and responsibilities under this Agreement.  Any resignation or removal of
a Trustee and appointment of a successor trustee pursuant to this Section 8.06
shall become effective upon such acceptance of appointment by the successor
trustee.

     (d) Any corporation into which a Trustee hereunder may be merged or with
which it may be consolidated, or any corporation resulting from any merger or
consolidation to which such Trustee hereunder shall be a party, shall be the
successor trustee under this Agreement without the execution or filing of any
paper, instrument or further act to be done on the part of the parties hereto,
anything herein, or in any agreement relating to such merger or consolidation,
by which any such Trustee may seek to retain certain powers, rights and
privileges theretofore obtaining for any period of time following such merger or
consolidation, to the contrary notwithstanding.

     Section 8.07.  Qualification of Trustee.  The Trustee and any successor
trustee shall be a corporation organized under laws of the United States, or any
state thereof, which is authorized under such laws to exercise trust powers and
has at all times an aggregate capital, surplus and undivided profits of not less
than $5,000,000.

     Section 8.08.  Collateral.  As collateral security for the prompt payment
to the Trustee of all reimbursement to which the Trustee is entitled hereunder
and of all sums at any time owed to or payable to the Trustee hereunder
(including, without limitation, the prompt reimbursement of the Trustee for any
sums that it may from time to time advance to the account of the Trust Fund),
the Trustee is hereby granted a first and prior lien and security interest in
and to the Trust Fund and all Securities now or hereafter included therein,
including (without limitation) those Securities listed in the Trust Agreement,
together with all Securities, obligations, Contract Securities and instruments
received in exchange or substitution therefor and all proceeds thereof and all
additions and substitutions.

                                   Article IX

                                  Termination

     Section 9.01.  Procedure upon Termination.  This Agreement and the trust
created hereby shall terminate as to an individual Trust Fund upon the maturity,
redemption, sale or other disposition, as the case may be, of the last Security
held hereunder in such Trust Fund, unless sooner terminated as hereinbefore
specified, and may be terminated at any time by written instrument executed by
the Depositor and consented to by holders of Units representing 66-2/3% of the
Units of such Trust Fund then outstanding under this Agreement; provided, that
in no event shall any individual Trust Fund continue beyond the Mandatory
Termination Date for such Trust Fund.

                                     -46-
<PAGE>

     Written notice of any termination, specifying the time or times at which
any Unitholder holding Certificates may surrender such Certificates for
cancellation and the date, determined by the Trustee, upon which the transfer
books of the Trustee, maintained pursuant to Section 8.02, shall be closed with
respect to the terminated Trust Fund or the entire Fund, as the case may be,
shall be given by the Trustee to Unitholders of such terminated Trust Fund or
all Unitholders, as the case may be.

     Within a reasonable period of time after the termination of a Trust Fund or
the entire Fund, the Trustee shall sell all of the Securities then held, if any,
and shall:

          (a) deduct from the Income Account or to the extent that funds are
     not available in such Account, from the Capital Account of every Trust Fund
     separately and pay to itself individually an amount equal to the sum of (1)
     its accrued compensation for its ordinary services in connection with such
     Trust Fund, (2) any compensation due it for its extraordinary services in
     connection with such Trust Fund and (3) any other expenses, disbursements
     and advances in connection with such Trust Fund as provided herein;

          (b) deduct from the Income Account or to the extent that funds are
     not available in such account, from the Capital Account of every Trust Fund
     separately and pay accrued and unpaid fees in connection with such Trust
     Fund of the Evaluator, the Depositor and counsel, if any;

          (c) deduct from the Income Account, or to the extent that funds are
     not available from such Account, from the Capital Account of every Trust
     Fund separately any amounts which it in its sole discretion shall deem
     requisite to be deposited in the Reserve Account to provide for any
     applicable taxes or other governmental charges that may be payable out of
     such Trust Fund;

          (d) distribute to each Unitholder (upon surrender for cancellation of
     his Certificate or Certificates, if issued) such Unitholder's interest in
     the balances of the Income and, on the conditions set forth in Section 3.03
     hereof, the Reserve Accounts of the Trust Fund in which he holds Units;

          (e) either distribute in cash to each Unitholder (upon surrender for
     cancellation of his Certificate or Certificates, if issued) such
     Unitholder's pro rata share of the balance of the Capital Account, or, in
     the alternative, if offered by the terms of the Prospectus, distribute to
     each Unitholder who then owns at least that number of Units set forth in
     the Prospectus and who has requested an In Kind Distribution under the
     conditions set forth in Section 5.02, such holder's In Kind Distribution as
     set forth in Section 5.02; and

          (f) together with such distribution to each Unitholder as provided
     for in paragraph (d) and (e), furnish to each such Unitholder a final
     statement as of the date of the computation of the amount distributable to
     Unitholders of the same Trust Fund, setting forth the data and information
     in substantially the form and manner provided for in Section 3.05 hereof.

                                     -47-
<PAGE>

     Any Unitholder who receives an In Kind Distribution, if offered by the
terms of the Prospectus, shall receive such Distribution in the same manner as
is provided in connection with redemptions in Section 5.02.

     If a Trust Fund has elected to be treated as a "regulated investment
company" as defined in the Internal Revenue Code, and if the Trust Fund involved
seeks to consist of securities included in a securities index, then
notwithstanding anything to the contrary herein, if at any time the index shall
no longer be compiled, maintained or made available, the Depositor may (i)
direct that the Trust Fund created hereby continue to be operated hereunder
utilizing the components of the index as existed on the last date on which the
index components were available to a Trust Fund or (ii) direct the Trustee to
terminate this Agreement and the Trust Fund created hereby and liquidate the
Trust Fund in such manner as the Depositor shall direct.

     Section 9.02.  Notice to Unitholders.  In the event that all of the
Unitholders holding Certificates shall not surrender their Certificates for
cancellation within six months after the time specified in the applicable,
above-mentioned notice, the Trustee shall give a second written notice to the
remaining Unitholders to surrender their Certificates for cancellation and
receive the liquidating distribution with respect thereto.  If within one year
after the second notice all the Certificates issued shall not have been
surrendered for cancellation, the Trustee may take appropriate steps or may
appoint an agent to take appropriate steps, to contact the remaining Unitholders
concerning surrender of their Certificates and the cost thereof shall be paid
out of the moneys and other assets which remain in the affected Trust Fund.

     Section 9.03.  Moneys to be Held in Trust Without Interest.  The Trustee
shall be under no liability with respect to moneys in the Income, Capital and
Reserve Accounts upon termination, except to hold the same in trust without
interest.

     Section 9.04.  Dissolution of Depositor Not to Terminate.  The
dissolution of the Depositor shall not, subject to Section 8.01(f), operate to
terminate this Agreement or the Fund or any individual Trust Fund.

                                   Article X

                            Miscellaneous Provisions

     Section 10.01.  Amendment and Waiver.  (a) For each Trust Fund other than
those that elect to be treated as a "regulated investment company" as defined in
the Internal Revenue Code, this Agreement may be amended from time to time by
the Depositor and the Trustee without the consent of any of the Unitholders (1)
to cure any ambiguity or to correct or supplement any provisions contained
herein which may be defective or inconsistent with any other provision contained
herein; (2) to change any provision hereof as may be required by the Securities
and Exchange Commission or any successor governmental agency exercising similar
authority; or (3) to make such other provisions in regard to matters or
questions arising hereunder as shall not adversely affect the interest of the
Unitholders (as determined in good faith by the Depositor and the Trustee). This
Agreement may also be amended from time to time by the Depositor and the

                                     -48-
<PAGE>

Trustee (or the performance of any of the provisions of this Agreement may be
waived) with the consent of holders of Units representing 66-2/3% of the Units
at the time outstanding under the Trust Agreement of the individual Trust Fund
or Trust Funds affected for the purpose of adding any provisions of this
Agreement or of modifying in any manner the rights of the holders of Units of
such Trust Fund or Trust Funds; provided, however, that in no event may any
amendment be made which would (1) alter the rights to the Unitholders as against
each other, (2) provide the Trustee with the power to engage in business or
investment activities other than as specifically provided in this Agreement or
(3) adversely affect the characterization of a Trust Fund as a grantor trust for
federal income tax purposes; provided, further, that the consent of 100% of the
Unitholders of any individual Trust Fund is required to amend this Agreement (1)
to increase the number of Units of such Trust Fund issuable hereunder above the
number of Units specified in the Prospectus or such lesser amount as may be
outstanding at any time during the term of this Agreement, (2) to permit, in
addition to acquisitions permitted under Section 3.10 hereof, the acquisition
hereunder of any Securities for such Trust Fund different from those specified
in Schedule A to the Trust Agreement, (3) to reduce the aforesaid percentage of
Units the holders of which are required to consent to certain amendments and (4)
to reduce the interest in such Trust Fund represented by any Units of such Trust
Fund.

     (b) If a Trust Fund has elected to be treated as a "regulated investment
company" as defined in the Internal Revenue Code and notwithstanding Section
10.01(a), this Agreement may be amended from time to time by the Depositor and
the Trustee without the consent of any of the Unitholders (1) to cure any
ambiguity or to correct or supplement any provisions contained herein which may
be defective or inconsistent with any other provision contained herein; (2) to
change any provision hereof as may be required by the Securities and Exchange
Commission or any successor governmental agency exercising similar authority;
(3) to make such amendments as may be necessary for each Trust Fund to continue
to qualify as a regulated investment company for federal income tax purposes; or
(4) to make such other provisions in regard to matters or questions arising
hereunder as shall not adversely affect the interest of the Unitholders (as
determined in good faith by the Depositor and the Trustee).  This Agreement may
also be amended from time to time by the Depositor and the Trustee (or the
performance of any of the provisions of this Agreement may be waived) with the
consent of holders of Units representing 66-2/3% of the Units at the time
outstanding under the Trust Agreement of the individual Trust Fund or Trust
Funds affected for the purpose of adding any provisions of this Agreement or of
materially modifying in any manner the rights of the holders of Units of such
Trust Fund or Trust Funds; provided, however, that in no event may any amendment
be made which would (1) alter the rights to the Unitholders as against each
other, (2) provide the Trustee with the power to engage in business or
investment activities other than as specifically provided in this Agreement or
(3) adversely affect the characterization of a Trust Fund as a regulated
investment company for federal income tax purposes; provided, further, that the
consent of 100% of the Unitholders of any individual Trust Fund is required to
amend this Agreement (1) to reduce the aforesaid percentage of Units the holders
of which are required to consent to certain amendments and (2) to reduce the
interest in such Trust Fund represented by any Units of such Trust Fund.

     Promptly after the execution of any amendment requiring the consent of the
Unitholders or any of any other amendment if directed by the Depositor, the
Trustee shall furnish written

                                     -49-
<PAGE>

notification of the substance of such amendment to each Unitholder then of
record affected thereby.

     It shall not be necessary for the consent of Unitholders under this Section
10.01 or under Section 9.01 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 Unitholders shall be subject to such
reasonable regulations as the Trustee may prescribe.

     Section 10.02.  Initial Costs.  Subject to reimbursement as hereinafter
provided, the cost of organizing the Trust Funds, and the sale of the Trust Fund
Units shall be borne by the Depositor; provided, however, that the liability on
the part of the Depositor under this section shall not include any fees or other
expenses incurred in connection with the administration of the Trust Funds
subsequent to the deposit referred to in Section 2.01. At the earlier of six
months after the Initial Date of Deposit or the conclusion of the primary
offering period (as certified by the Depositor to the Trustee), the Trustee
shall withdraw from the Account or Accounts specified in the Prospectus or, if
no Account is therein specified, from the Capital Account, and pay to the
Depositor the Depositor's reimbursable expenses of organizing the Trust Funds in
an amount certified to the Trustee by the Depositor. In no event shall the
amount paid by the Trustee to the Depositor for the Depositor's reimbursable
expenses of organizing a Trust Fund exceed the estimated per Unit amount of
organization costs set forth in the prospectus for the Trust Fund multiplied by
the number of Units of the Trust Fund outstanding at the earlier of six months
after the Initial Date of Deposit or the end of the initial offering period; nor
shall the Depositor be entitled to or request reimbursement for expenses of
organizing a Trust Fund incurred after the earlier of six months after the
Initial Date of Deposit or the end of the initial offering period.  If the cash
balance of the Capital Account is insufficient to make such withdrawal, the
Trustee shall, as directed by the Depositor, sell Securities identified by the
Depositor, or distribute to the Depositor Securities having a value, as
determined under Section 4.01 as of the date of distribution, sufficient for
such reimbursement.  Securities sold or distributed to the Depositor to
reimburse the Depositor pursuant to this Section shall be sold or distributed by
the Trustee to the extent practicable, in the percentage ratio then existing
(unless the Trust Fund elects to be treated as a "regulated investment company"
as defined in the United States Internal Revenue Code (the "Internal Revenue
Code"), in which case sales or distributions by the Trustee shall be made in
accordance with the instructions of the Depositor or its designees).  The
reimbursement provided for in this section shall be for the account of the
Unitholders of record at the earlier of six months after the Initial Date of
Deposit or the conclusion of the primary offering period.  Any assets deposited
with the Trustee in respect of the expenses reimbursable under this Section
10.02 shall be held and administered as assets of the Trust Funds for all
purposes hereunder.  The Depositor shall deliver to the Trustee any cash
identified in the Statement(s) of Condition of the Trust Funds included in the
Prospectus not later than the 10 calendar days following the Initial Date of
Deposit or deposit of additional Securities, as applicable and the Depositor's
obligation to make such delivery shall be secured by the letter of credit
deposited pursuant to Section 2.01.  Any cash which the Depositor has identified
as to be used for reimbursement of expenses pursuant to this Section 10.02 shall
be held by the Trustee, without interest, and reserved for such purpose and,
accordingly, prior to the earlier of six months after the Initial Date of
Deposit or the conclusion of the primary offering period, shall not be subject
to distribution or, unless the

                                     -50-
<PAGE>

Depositor otherwise directs, used for payment of redemptions in excess of the
per Unit amount payable pursuant to the next sentence. If a Unitholder redeems
Units prior to the earlier of six months after the Initial Date of Deposit or
the conclusion of the primary offering period, the Trustee shall pay to the
Unitholder, in addition to the Redemption Value of the tendered Units, unless
otherwise directed by the Depositor, an amount equal to the estimated per Unit
cost of organizing the Trust Fund set forth in the Prospectus, or such lower
revision thereof most recently communicated to the Trustee by the Depositor
pursuant to Section 5.01, multiplied by the number of Units tendered for
redemption; to the extent the cash on hand in a Trust Fund is insufficient for
such payment, the Trustee shall have the power to sell Securities in accordance
with Section 5.02. As used herein, the Depositor's reimbursable expenses of
organizing a Trust Fund shall include the cost of the initial preparation and
typesetting of the registration statement, prospectuses (including preliminary
prospectuses), the agreement, and other documents relating to the Trust Fund,
SEC and state blue sky registration fees, the cost of the initial valuation of
the portfolio and audit of the Trust Fund, the initial fees and expenses of the
Trustee, and legal and other out-of-pocket expenses related thereto, but not
including the expenses incurred in the printing of preliminary prospectuses and
prospectuses, expenses incurred in the preparation and printing of brochures and
other advertising materials and any other selling expenses.

     Section 10.03.  Registration (Initial and Current) of Units and Fund.  The
Depositor agrees and undertakes on its own part to register the Units, each
Trust Fund and the Fund with the Securities and Exchange Commission and under
the Blue Sky laws of such states as the Depositor may select.

     Section 10.04.  Certain Matters Relating to Unitholders.  (a) The death or
incapacity of any Unitholder shall not operate to terminate this Agreement, the
Fund or the Trust Fund in which he holds Units nor entitle his 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 the Fund or such Trust
Fund, nor otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them. Each Unitholder expressly waives any right he may
have under any rule of law, or the provisions of any statute, or otherwise, to
require the Trustee at any time to account, in any manner other than as
expressly provided in this Agreement, in respect of the Securities or moneys
from time to time received, held and applied by the Trustee hereunder.

     (b) No Unitholder shall have any right to vote except as provided in
Sections 9.01 and 10.01 or in any manner otherwise to control the operation of
the Fund or the obligations of the parties hereto, nor shall anything set forth
in this Agreement or the Trust Agreement or contained in the terms of any
Certificates which may have been issued be construed so as to constitute the
Unitholders from time to time as partners or members of an association; nor
shall any Unitholder ever be under any liability to any third persons by reason
of any action taken by the parties to this Agreement, or for any other cause
whatsoever.

     (c) By the purchase and acceptance or other lawful delivery and acceptance
of any Unit, whether certificated or not, the Unitholder shall be deemed to be a
beneficiary of the Trust created by this Agreement and the Trust Agreement and
vested with all right, title and interest in the Trust Fund therein created to
the extent of the Unit or Units set forth whether evidenced by

                                     -51-
<PAGE>

such Certificate or held in uncertificated form, subject to the terms and
conditions of this Agreement and the Trust Agreement.

     (d) A Unitholder may at any time prior to the Evaluation Time on the date
the Trust is terminated tender his Units or his Certificate(s) if held in
certificated form (including any temporary Certificate or other evidence of
ownership of Units of the Trust Fund, issued by the Trustee or the Depositor) to
the Trustee for redemption, subject to and in accordance with Section 5.02.

     Section 10.05.  New York Law to Govern.  This Agreement is executed and
delivered in the State of New York, and all laws or rules of construction of
such State, except for provisions with respect to choice of law, shall govern
the rights of the parties hereto and the Unitholders and the interpretation of
the provisions hereof.

     Section 10.06.  Notices.  Any notice, demand, direction or instruction to
be given to the Depositor hereunder shall be in writing and shall be duly given

mailed, first class with proper postage prepaid, or delivered to each Unitholder
at the address of such holder appearing on the registration books of the
Trustee.

     Section 10.07.  Severability.  If any one or more of the covenants,
agreements, provisions or terms shall be for any reason whatsoever held invalid,
then such covenants, agreements, provisions or terms shall be deemed severable
from the remaining covenants, agreements, provisions or terms of this Agreement
and shall in no way affect the validity or enforceability of the other
provisions of this Agreement or of any Certificates or the rights of the holders
thereof.

     Section 10.08.  Separate and Distinct Series.  Each series of Nuveen Unit
Trust to which these Standard Terms and Conditions of Trust shall be applicable
shall, for all financial and administrative purposes, be considered separate and
distinct from every other series, and neither the assets of nor the expenses of
any one series shall be applied or charged against any other series.

                                     -52-
