By:
       Authorized Signatory                   By:
                                                  Authorized Officer
          The following is a summary of certain provisions of the Indenture (a
copy of which is on file and available for inspection to the holder hereof at
the corporate trust office of the Trustee), to which this Certificate is subject
and to which reference is hereby made. All of the terms, conditions and
covenants of the Indenture are incorporated herein by reference as fully as if
set forth herein. The Trust consists of (1) such of the interest-bearing debt
securities and obligations that may be deposited in trust and listed in Schedule
A of the Indenture (including contracts, if any, for the purchase of certain of
such securities and obligations together with the cash, cash equivalents and/or
an irrevocable letter of credit issued by a commercial bank in the amount
required for such purchase) and any other securities that may be deposited in
the Trust in exchange or substitution therefor in accordance with the Indenture,
as may from time to time continue to be held in the Trust and (2) such cash
amounts as from time to time may be held in the Interest Account and the
Principal Account maintained under the Indenture in the manner described below.
          At any given time this Certificate shall represent a fractional
undivided interest in the Trust, the numerator of which fraction shall be the
number of units set forth on the face hereof and the denominator of which shall
be the total number of units of fractional undivided interest represented by all
Certificates of this Series which are outstanding at such time.
          The registered holder of this Certificate is entitled at any time upon
tender of this Certificate to the Trustee at its corporate trust office in the
City of New York, endorsed in blank or accompanied by all necessary instruments
of assignment and
C/M:  11939.0001 407314.1
transfer in proper form, and upon payment of any tax or other governmental
charges, to receive on the seventh calendar day following the day on which such
tender is made, or, if such calendar day is not a business day, on the first
business day prior to such calendar day, an amount in cash equal to the
evaluation of the fractional undivided interest in the Trust evidenced by this
Certificate, upon the basis provided for in the Indenture (the "Redemption
Price"). The right of redemption may be suspended and the date of payment may be
postponed for any period during which the New York Stock Exchange is closed or
trading on that,Exchange is restricted, or for any period during which an
emergency exists so that disposal of the obligations held in the Trust is not
reasonably practicable or it is not reasonably practicable fairly to determine
the value of such obligations in accordance with the Indenture or for such other
periods as the Securities and Exchange Commission may by order permit.
          The Trustee is irrevocably authorized in its discretion, in lieu of
redeeming this Certificate if tendered for redemption, to sell this Certificate
in the over-the-counter market or by private sale for the account of the
Certificateholder at a price which will return to the Certificateholder an
amount in cash, net after deducting brokerage commissions, transfer taxes and
other charges, equal to or in excess of the Redemption Price for this
Certificate. In the event of any such sale the Trustee shall pay the net
proceeds thereof to the Certificateholder on the day he would otherwise be
entitled to receive payment of the Redemption Price.
          Interest received by the Trustee as part of the Trust (including
interest accrued and unpaid prior to the day of deposit of any obligation in the
Trust and that part of the proceeds of the sale, liquidation, redemption or
maturity of any such obligation which represents accrued interest) shall be
credited by the Trustee to the Interest Account. The fractional undivided
interest represented by this Certificate in the balance in the Interest Account
(after the deductions referred to below) shall first be computed as of the
semi-annual Record Date (as defined in the Indenture). The next computation
shall be made as of the next succeeding semi-annual Record Date, and thereafter
as of the first day of June and December of each year commencing with the first
such day following the date of this Certificate.
          An amount in cash equal to the fractional undivided interest in the
Interest Account (on the basis set forth below) computed as set forth above,
shall be distributed on the 15th day of the respective months, or within a
reasonable period of time thereafter, to the registered holder of this
Certificate at the close of business on the first day of the month in which such
distribution is made.
C/M:  11939.0001 407314.1
          The Trustee shall make semi-annual distributions from the Interest
Account on the basis of one-half of the estimated annual interest income
expected by the Trustee to be received by the Trust in the ensuing twelve month
period, after deduction of the estimated costs and expenses to be incurred
during such period, except as otherwise hereafter provided. To the extent cash
in the Interest Account is insufficient for any distribution the Trustee shall
advance its own funds sufficient therefor and shall be entitled to
reimbursement, without interest, out of interest received by the Trust
subsequent to such advance.
          All moneys (other than interest) received by the Trustee, as part of
the Trust (including amounts received from the sale, liquidation, redemption or
maturity of any obligation held in the Trust) shall be credited by the Trustee
to a separate Principal Account. The fractional undivided interest represented
by this Certificate in the cash balance in the Principal Account (after the
deductions referred to below) shall be computed as of the first day of June and
December of each year, commencing with the semi-annual Record Date. An amount in
cash equal to the fractional undivided interest in the Principal Account,
computed as set forth above, shall be distributed on the fifteenth day of the
respective months, or within a reasonable time thereafter, to the registered
holder of this Certificate at the close of business on the first day of such
month. The Trustee shall not be required to make a distribution from the
Principal Account unless the cash balance on such deposit therein available for
such distribution shall be sufficient to permit the distribution of at least
$1.00 per Unit.
          Distributions from the Interest and Principal Accounts shall be made
to the registered holder hereof by check mailed to the address of such holder
appearing in the registration books of the Trustee.
          From time to time deductions shall be made from the Interest Account
and Principal Account, as more fully set forth in the Indenture, for
redemptions, compensation of the Trustee, compensation of the Evaluator, payment
of the Depositor's fee for services as such, reimbursement of certain expenses
incurred or advances made by or on behalf of the Trustee, certain legal
expenses, and payment of, or the establishment of a reserve for, applicable
taxes or governmental charges, if any.
          Within a reasonable period of time after the end of each calendar year
the Trustee shall furnish to the registered holder of this Certificate a
statement setting forth, among other things, the amounts received by the Trust
and deductions therefrom and the amounts distributed during the preceding year
in respect of interest on, payments and prepayments of principal of, and sales,
redemptions or maturities of, obligations held in the Trust.
C/M:  11939.0001 407314.1
          This Certificate shall be transferable by the registered holder hereof
by presentation and surrender at the corporate trust office of.the Trustee
properly endorsed or accompanied by a written instrument or instruments of
transfer in form satisfactory to the Trustee and executed by the registered
holder hereof or his authorized attorney. Certificates of this Series are
interchangeable for one or more Certificates in an equal aggregate number of
Units of fractional undivided interest at the corporate trust office of the
Trustee, in denominations of a single Unit of fractional undivided interest or
any whole multiple thereof.
          The holder of this Certificate may be required to pay a transfer
charge in connection with the transfer or exchange of this Certificate, as well
as any tax or other governmental charge that may be imposed in connection with
the transfer, exchange or other surrender of this Certificate.
          The holder of this Certificate, by virtue of the acceptance hereof,
assents to and shall be bound by the terms of the Indenture, a copy of which is
on file and available for inspection at the corporate trust office of the
Trustee, to which reference is made for all the terms, conditions and covenants
thereof.
          The Trustee may deem and treat the person in whose name this
Certificate is registered upon the books of the Trustee as the owner hereof for
all purposes and the Trustee shall not be affected by any notice to the
contrary.
          The Indenture and the Trust created thereby shall terminate upon the
maturity, redemption, sale or other disposition of the last security held
thereunder, provided, however, that in no event shall the Indenture and the
Trust continue beyond the end of the calendar year preceding the fiftieth
anniversary of the execution of the Indenture. The Indenture also provides that
the Trust may be terminated at any time by the written consent of the holders of
Certificates representing all of the Units outstanding and under certain
circumstances which include a decrease in the value of the Trust to less than
40% of the initial aggregate principal amount of the securities deposited in the
Trust. Upon any termination the Trustee shall fully liquidate the securities
then held, if any, and distribute pro rata the funds then held in the Trust upon
surrender of the Certificates, all in the manner provided in the Indenture. Upon
termination, the Trustee shall be under no further obligation with respect to
the Trust, except to hold the funds in trust without interest until distribution
as aforesaid and shall have no duty upon any such termination to communicate
with the holder hereof other than by mail at the address of such holder
appearing on the registration books of the Trustee.
C/M:  11939.0001 407314.1
                        STATEMENT REGARDING DISTRIBUTION
          On the face of this Certificate it is indicated whether the registered
holder hereof has elected to receive distributions from the Interest Account
monthly, semi-annually, or annually.
          This Certificate by its terms provides that distributions from the
Interest Account shall first be computed as of the semi-annual Record Date, and
thereafter as of the next succeeding semi-annual Record Date commencing with the
first such day following the date of the Certificate, and an amount in cash
equal to the share of the Interest Account represented by this Certificate
distributed on the fifteenth day of the respective months next following such
computations, or within a reasonable period of time thereafter, to the
registered holder of this Certificate at the close of business on the first day
of the month in which the distribution is made.
          If monthly distributions have been selected, the fractional undivided
interest represented by this Certificate in the balance in the Interest Account,
after the first distribution and after the deductions referred to above, will be
computed monthly as of the first day of each month of each year, commencing with
the monthly Record Date, and an amount in cash as thus computed will be
distributed to the holder hereof at such date of computation on or shortly after
the fifteenth day of each month.
          If annual distributions have been selected, the fractional undivided
interest represented by this Certificate in the balance in the Interest Account,
after the first distribution and after the deductions referred to above, will be
computed annually as of the first day of December of each year, commencing with
the annual Record Date and an amount in cash as thus computed will be
distributed to the holder hereof at such date of computation on or shortly after
the fifteenth day of each December.
          All Certificateholders of record as of the First Record Date (as
defined in the Indenture) however, regardless of the plan of distribution
selected, will receive the distribution to be made on or shortly after the First
Payment Date (as defined in the Indenture) and thereafter, distributions will be
made monthly, semi-annually or annually depending upon the plan of distribution,
chosen by the holder hereof.
          The plan of distribution chosen by the registered holder hereof may be
changed by written notice to the Trustee not later than November 1 in any
calendar year by surrender to the Trustee of this Certificate, together with a

By:
       Authorized Signatory                By:
                                                  Authorized Officer
          The following is a summary of certain provisions of the Indenture (a
copy of which is on file and available for inspection to the holder hereof at
the corporate trust office of the Trustee), to which this Certificate is subject
and to which reference is hereby made. All of the terms, conditions and
covenants of the Indenture are incorporated herein by reference as fully as if
set forth herein. The Trust consists of (1) such of the interest-bearing debt
securities and obligations that may be deposited in trust and listed in Schedule
A of the Indenture (including contracts, if any, for the purchase of certain of
such securities and obligations together with the cash, cash equivalents and/or
an irrevocable letter of credit issued by a commercial bank in the amount
required for such purchase) and any other securities that may be deposited in
the Trust in exchange or substitution therefor in accordance with the Indenture,
as may from time to time continue to be held in the Trust and (2) such cash
amounts as from time to time may be held in the Interest Account and the
Principal Account maintained under the Indenture in the manner described below.
          At any given time this Certificate shall represent a fractional
undivided interest in the Trust, the numerator of which fraction shall be the
number of units set forth on the face hereof and the denominator of which shall
be the total number of units of fractional undivided interest represented by all
Certificates of this Series which are outstanding at such time.
          The registered holder of this Certificate is entitled at any time upon
tender of this Certificate to the Trustee at its
C/M:  11939.0001 407314.1
corporate trust office in the City of New York, endorsed in blank or accompanied
by all necessary instruments of assignment and transfer in proper form, and upon
payment of any tax or other governmental charges, to receive on the seventh
calendar day following the day on which such tender is made, or, if such
calendar day is not a business day, on the first business day prior to such
calendar day, an amount in cash equal to the evaluation of the fractional
undivided interest in the Trust evidenced by this Certificate, upon the basis
provided for in the Indenture (the "Redemption Price"). The right of redemption
may be suspended and the date of payment may be postponed for any period during
which the New York Stock Exchange is closed or trading on that Exchange is
restricted, or for any period during which an emergency exists so that disposal
of the obligations held in the Trust is not reasonably practicable or it is not
reasonably practicable fairly to determine the value of such obligations in
accordance with the Indenture or for such other periods as the Securities and
Exchange Commission may by order permit.
          The Trustee is irrevocably authorized in its discretion, in lieu of
redeeming this Certificate if tendered for redemption, to sell this Certificate
in the over-the-counter market or by private sale for the account of the
Certificateholder at a price which will return to the Certificateholder an
amount in cash, net after deducting brokerage commissions, transfer taxes and
other charges, equal to or in excess of the Redemption Price for this
Certificate. In the event of any such sale the Trustee shall pay the net
proceeds thereof to the Certificateholder on the day he would otherwise be
entitled to receive payment of the Redemption Price.
          Interest received by the Trustee as part of the Trust (including
interest accrued and unpaid prior to the day of deposit of any obligation in the
Trust and that part of the proceeds of the sale, liquidation, redemption or
maturity of any such obligation which represents accrued interest) shall be
credited by the Trustee to the Interest Account. The fractional undivided
interest represented by this Certificate in the balance in the Interest Account
(after the deductions referred to below) shall first be computed as of the
semi-annual Record Date (as defined in the Indenture). The next computation
shall be made as of the next succeeding semi-annual Record Date, and thereafter
as of the first day of June and December of each year commencing with the first
such day following the date of this Certificate.
          An amount in cash equal to the fractional undivided interest in the
Interest Account (on the basis set forth below) computed as set forth above,
shall be distributed on the 15th day of the respective months, or within a
reasonable period of time thereafter, to the registered holder of this
Certificate at the close of business on the first day of the month in which such
C/M:  11939.0001 407314.1
distribution is made.
          The Trustee shall make semi-annual distributions from the Interest
Account on the basis of one-half of the estimated annual interest income
expected by the Trustee to be received by the Trust in the ensuing twelve month
period, after deduction of the estimated costs and expenses to be incurred
during such period, except as otherwise hereafter provided. To the extent cash
in the Interest Account is insufficient for any distribution the Trustee shall
advance its own funds sufficient therefor and shall be entitled to
reimbursement, without interest, out of interest received by the Trust
subsequent to such advance.
          All moneys (other than interest) received by the Trustee, as part of
the Trust (including amounts received from the sale, liquidation, redemption or
maturity of any obligation held in the Trust) shall be credited by the Trustee
to a separate Principal Account. The fractional undivided interest represented
by this Certificate in the cash balance in the Principal Account (after the
deductions referred to below) shall be computed as of the first day of June and
December of each year, commencing with the semi-annual Record Date. An amount in
cash equal to the fractional undivided interest in the Principal Account,
computed as set forth above, shall be distributed on the fifteenth day of the
respective months, or within a reasonable time thereafter, to the registered
holder of this Certificate at the close of business on the first day of such
month. The Trustee shall not be required to make a distribution from the
Principal Account unless the cash balance on such deposit therein available for
such distribution shall be sufficient to permit the distribution of at least
$1.00 per Unit.
          Distributions from the Interest and Principal Accounts shall be made
to the registered holder hereof by check mailed to the address of such holder
appearing in the registration books of the Trustee.
          From time to time deductions shall be made from the Interest Account
and Principal Account, as more fully set forth in the Indenture, for
redemptions, compensation of the Trustee, compensation of the Evaluator, payment
of the Depositor's fee for services as such, reimbursement of certain expenses
incurred or advances made by or on behalf of the Trustee, certain legal expenses
and payment of, or the establishment of a reserve for, applicable taxes or
governmental charges, if any.
          Within a reasonable period of time after the end of each calendar year
the Trustee shall furnish to the registered holder of this Certificate a
statement setting forth, among other things, the amounts received by the Trust
and deductions therefrom and the amounts distributed during the preceding year
in respect of interest on, payments and prepayments of principal
C/M:  11939.0001 407314.1
of, and sales, redemptions or maturities of, obligations held in
the Trust.
          This Certificate shall be transferable by the registered holder hereof
by presentation and surrender at the corporate trust office of the Trustee
properly endorsed or accompanied by a written instrument or instruments of
transfer in form satisfactory to the Trustee and executed by the registered
holder hereof or his authorized attorney. Certificates of this Series are
interchangeable for one or more Certificates in an equal aggregate number of
Units of fractional undivided interest at the corporate trust office of the
Trustee, in denominations of a single Unit of fractional undivided interest or
any whole multiple thereof.
          The holder of this Certificate may be required to pay a transfer
charge in connection with the transfer or exchange of this Certificate, as well
as any tax or other governmental charge that may be imposed in connection with
the transfer, exchange or other surrender of this Certificate.
          The holder of this Certificate, by virtue of the acceptance hereof,
assents to and shall be bound by the terms of the Indenture, a copy of which is
on file and available for inspection at the corporate trust office of the
Trustee, to which reference is made for all the terms, conditions and covenants
thereof.
          The Trustee may deem and treat the person in whose name this
Certificate is registered upon the books of the Trustee as the owner hereof for
all purposes and the Trustee shall not be affected by any notice to the
contrary.
          The Indenture and the Trust created thereby shall terminate upon the
maturity, redemption, sale or other disposition of the last security held
thereunder, provided, however, that in no event shall the Indenture and the
Trust continue beyond the end of the calendar year preceding the fiftieth
anniversary of the execution of the Indenture. The Indenture also provides that
the Trust may be terminated at any time by the written consent of the holders of
Certificates representing all of the Units outstanding and under certain
circumstances which include a decrease in the value of the Trust to less than
40% of the initial aggregate principal amount of the securities deposited in the
Trust. Upon any termination the Trustee shall fully liquidate the securities
then held, if any, and distribute pro rata the funds then held in the Trust upon
surrender of the Certificates, all in the manner provided in the Indenture. Upon
termination, the Trustee shall be under no further obligation with respect to
the Trust, except to hold the funds in trust without interest until distribution
as aforesaid and shall have no duty upon any such termination to communicate
C/M:  11939.0001 407314.1
with the holder hereof other than by mail at the address of such bolder 
appearing on the registration books of the Trustee.
                        STATEMENT REGARDING DISTRIBUTION
          On the face of this Certificate it is indicated whether the registered
holder hereof has elected to receive distributions from the Interest Account
monthly, semi-annually, or annually.
          This Certificate by its terms provides that distributions from the
Interest Account shall first be computed as of the semi-annual Record Date, and
thereafter as of the next succeeding semi-annual Record Date commencing with the
first such day following the date of the Certificate, and an amount in cash
equal to the share of the Interest Account represented by this Certificate
distributed on the fifteenth day of the respective months next following such
computations, or within a reasonable period of time thereafter, to the
registered holder of this Certificate at the close of business on the first day
of the month in which the distribution is made.
          If monthly distributions have been selected, the fractional undivided
interest represented by this Certificate in the balance in the Interest Account,
after the first distribution and after the deductions referred to above, will be
computed monthly as of the first day of each month of each year, commencing with
the monthly Record Date, and an amount in cash as thus computed will be
distributed to the holder hereof at such date of computation on or shortly after
the fifteenth day of each month.
          If annual distributions have been selected, the fractional undivided
interest represented by this Certificate in the balance in the Interest Account,
after the first distribution and after the deductions referred to above, will be
computed annually as of the first day of December of each year, commencing with
the annual Record Date and an amount in cash as thus computed,ill be distributed
to the holder hereof at such date of computation on or shortly after the
fifteenth day of each December.
          All Certificateholders of record as of the First Record Date (as
defined in the Indenture) however, regardless of the plan of distribution
selected, will receive the distribution to be made on or shortly after the First
Payment Date (as defined in the Indenture) and thereafter, distributions will be
made monthly, semi-annually or annually depending upon the plan of distribution,
chosen by the holder hereof.
          The plan of distribution chosen by the registered holder hereof may be
changed by written notice to the Trustee not later than November 1 in any
calendar year by surrender to the
C/M:  11939.0001 407314.1
Trustee of this Certificate, together with a completed form for selection of
plan of distribution provided by the Trustee. A plan of distribution shall
continue in effect until changed as herein provided. A change in a plan of
distribution may only be made as indicated herein and will be effective as of
December 2 for the ensuing twelve months. Distributions to Certificateholders
who are participating in one of the optional plans for distribution of interest
shall not be affected because of advancements of the Trustee for the purpose of
equalizing distributions to Certificateholders participating in a different
plan.
