                     WITH THE SECURITY OF U.S. TREASURIES
- -----------------------------------------------------------------------------
    

   The investment objective of this Trust is to preserve capital while
providing for capital appreciation through an investment in "zero-coupon"
United States Treasury obligations (the "Treasury Obligations") and equity
stocks having, in Sponsor's opinion on the Date of Deposit, potential for
appreciation (the "Stocks"). The value of the Units will fluctuate with the
value of the portfolio of underlying securities.

   The minimum purchase is $1,000 except that the minimum purchase in
connection with an Individual Retirement Account (IRA) or other tax-deferred
retirement plan is $250. Only whole Units may be purchased.

ESSENTIAL INFORMATION REGARDING THE TRUST (CONTINUED)

   
   The Trust. The objective of the PaineWebber Pathfinders Trust, Treasury
and Growth Stock Series 16 (the "Trust") is preservation of capital and
capital appreciation through an investment in the principal or interest
portions of stripped "zero-coupon" United States Treasury notes or bonds as
the case may be (the "Treasury Obligations"), and equity stocks (the "Stock")
which, in Sponsor's opinion on the Initial Date of Deposit, have potential
for capital appreciation (collectively, the "Securities"). The stripped
Treasury Obligations in the Trust portfolio are interest-only portions of
United States Treasury Obligations (as further discussed under "Risk Factors
and Special Characteristics"), maturing on February 15, 2004, represent
approximately 52% of the aggregate market value of the Trust portfolio and
the Stocks represent approximately 48% of the aggregate market value of the
Trust portfolio. The stripped Treasury Obligations, as discussed below, make
no payment of current interest, but rather make a single payment upon their
stated maturity. Because the maturity value of the Treasury Obligations is
backed by the full faith and credit of the United States, the Sponsor
believes that the Trust provides an attractive combination of safety and
appreciation for purchasers who hold Units until the Trust's termination. The
Trust has been formulated so that the portion of the Trust invested in
stripped Treasury Obligations is designed to provide an approximate return of
principal invested on the Mandatory Termination Date for purchasers on the
Initial Date of Deposit. (See "Essential Information--Distributions".)
Therefore, even if the Stocks are valueless upon termination of the Trust,
and if the Treasury Obligations are held until their maturity in proportion
to the Units outstanding, purchasers will receive, at the termination of the
Trust, $1,000 per 1,000 Units purchased. This feature of the Trust provides
that Unitholders who hold their units to the Mandatory Termination Date of
the Trust on March 2, 2004, will receive the same amount as they originally
invested, although they would have foregone earning any interest on the
amounts involved and will not protect their principal on a present value
basis, assuming the Stocks are valueless. Therefore, the Trust may be an
attractive investment to those persons who buy their Units during the initial
offering period and hold such Units throughout the life of the Trust until
the Trust matures.
    

   Summary of Risk Factors. The stripped Treasury Obligations may appreciate
or depreciate in value depending upon economic and market conditions. (For a
further discussion of stripped Treasury Obligations, see "Risk Factors and
Special Considerations.") The Stock may appreciate or depreciate in value (or
pay dividends) depending on the full range of economic and market influences
affecting corporate profitability, the financial condition of issuers, the
prices of equity securities in general and the Stock in particular and the
risk inherent in an investment made in common stocks in general. In addition,
the stripped Treasury Obligations may fluctuate substantially in value and
may be subject to greater fluctuations in value during the life of the Trust
than might be experienced by current interest-bearing Treasury Obligations
which distribute income regularly. There is no assurance that the Trust's
objective will be achieved at the Trust's intended maturity or if the Trust
is terminated or Units redeemed prior to the Trust's intended maturity. The
value of the Securities and, therefore, the value of Units may be expected to
fluctuate. Purchasers who purchase Units subsequent to the Initial Date of
Deposit will receive, if the pro rata portion of the Treasury Obligations are
held until maturity, $1,000 per 1,000 Units as a return of such purchaser's
principal investment, regardless of the purchase price paid by such
purchaser. (See "Risk Factors and Special Considerations.")

 The Composition of the Portfolio.  PaineWebber understands the importance of
long-term financial goals such as planning for retirement, funding a child's
education, or trying to build wealth toward some other objective.

   In PaineWebber's view, one of the most important investment decisions an
investor faces may be determining how to best allocate his investments to
capture growth opportunities without exposing his

                                3


APITAL PRINTING SYSTEMS]      
<PAGE>

portfolio to undue risk. For long-term capital growth, many investment
experts recommend stocks. As with all investments, the higher return
potential of equities is typically associated with higher risk. With this in
mind, PaineWebber designed a portfolio to meet the needs of investors
interested in building wealth prudently over a long-term time horizon by
pairing the security of U.S. Treasury bonds with the growth potential of
Stocks.

   The main objective of PaineWebber in constructing the portfolio of stocks
was to select a group of stocks which, in PaineWebber's view, would be
capable of, over the long term, closely tracking the performance of the
market as measured by the S&P 500. The S&P 500 is an unmanaged index of 500
stocks calculated under the auspices of Standard & Poor's, which, in
PaineWebber's view, is a broadly diversified, representative segment of the
market of all publicly traded stocks in the United States.

   To achieve this result, a computer program was run against the 500 S&P
stocks to construct the portfolio by identifying the 40 S&P 500 stocks
(excluding IBM and General Electric) which have the highest correlation with
the S&P 500 Index with the smallest tracking error.

   
   The Trust portfolio, in PaineWebber's opinion, is comprised of a
diversified group of companies representing various industries. These are
common stocks issued by companies who may receive income and derive revenues
from multiple industry sources but whose primary source is listed in the
table below. For a list of the individual common stocks comprising each
industry group listed below, investors should consult the "Schedule of
Investments" herein.

   The Sponsor anticipates that, based upon last dividends actually paid,
dividends from the Stock will be sufficient (i) to pay expenses of the Trust
(see "Expenses of the Trust" herein), and (ii) after such payment, to make
distributions of such to Unitholders as described below under
"Distributions".
    

   Additional Deposits. After the first deposit on the Initial Date of
Deposit the Sponsor may, from time to time, cause the deposit of additional
Securities in the Trust where additional Units are to be offered to the
public, maintaining, exactly, the original percentage relationship between
the maturity

                                4



      
<PAGE>

values of the Treasury Obligations and the number of shares of the Stocks
deposited on the Initial Date of Deposit, subject to certain adjustments.
Costs incurred in acquiring such additional Stocks which are not listed on
any national securities exchange, including brokerage fees, stamp taxes and
certain other costs associated with purchasing such additional Stocks, will
be borne by the Trust. Investors purchasing Units during the initial public
offering period will experience a dilution of their investment as a result of
such brokerage fees and other expenses paid by the Trust during additional
deposits of Securities purchased by the Trustee with cash or cash equivalents
pursuant to instructions to purchase such Securities. (See "The Trust" and
"Risk Factors and Special Considerations".)

   Termination. As directed by the Sponsor, approximately 30 days prior to
the maturity of the Treasury Obligations the Trustee will begin to sell the
Stocks held in the Trust. Stocks having the greatest amount of capital
appreciation will be sold first. In certain circumstances, monies held upon
the sale of Securities may, at the direction of the Sponsor, be invested for
the benefit of Unitholders in United States Treasury obligations which mature
on or prior to the next distribution date (see "Administration of the
Trust--Reinvestment"), otherwise monies held upon the sale or maturity of
Securities will be held in non-interest bearing accounts created by the
Indenture until distributed and will be of benefit to the Trustee. During the
life of the Trust, Securities will not be sold to take advantage of market
fluctuations. The Trust will terminate within 15 days after the Treasury
Obligations mature. (See "Termination of the Trust" and "Federal Income
Taxes".)

   Public Offering Price. The Public Offering Price per Unit is computed by
dividing the Trust Fund Evaluation by the number of Units outstanding and
then adding a sales charge of 4.75% of the Public Offering Price (4.99% of
the net amount invested). The sales charge is reduced after the first year
and on a graduated scale for sales involving at least $50,000 or 50,000 Units
and will be applied on whichever basis is more favorable to the purchaser.
(See "Public Offering of Units--Sales Charge and Volume Discount".)

   The public offering price on the Date of Deposit is determined on the
basis of the value of the Securities as of the close of business on the
preceding business day (i.e., by "backward pricing") pursuant to an exemptive
order of the Securities and Exchange Commission, which applies only to
purchase orders received on the Initial Date of Deposit. As a condition of
that order, however, if the public offering price based on the value of the
Securities as of the close of business on the Initial Date of Deposit (i.e.,
by "forward pricing") would be less than $.97 1/2 , then purchase orders
received on that day will be filled on the basis of the lower public offering
price.

   Distributions. The Trustee will distribute any net income and principal
received quarterly on the Distribution Dates. Income with respect to the
original issue discount on the Treasury Obligations will not be distributed
although Unitholders will be subject to income tax at ordinary income rates
as if a distribution had occurred. (See "Federal Income Taxes".) Upon
termination of the Trust, the Trustee will distribute to each Unitholder his
pro rata share of the Trust's assets, less expenses. The sale of Stocks in
the Trust in the period prior to termination and upon termination may result
in a lower amount than might otherwise be realized if such sale were not
required at such time due to impending or actual termination of the Trust.
For this reason, among others, the amount realized by a Unitholder upon
termination may be less than the amount paid by such Unitholder. Unless a
Unitholder purchases Units on the Date of Deposit and unless the Treasury
Obligations in proportion to the Units outstanding remain in the Trust, total
distributions, including distributions made upon termination of the Trust,
may be less than the amount paid for a Unit.

   Market for Units. The Sponsor, though not obligated to do so, presently
intends to maintain a secondary market for Units based upon the bid side
evaluation of the Treasury Obligations. The public

                                5



      
<PAGE>

offering price in the secondary market will be based upon the value of the
Securities next determined after receipt of a purchase order plus the
applicable sales charge. (See "Public Offering of Units--Public Offering
Price" and "Valuation".) If a secondary market is not maintained, a
Unitholder may dispose of his Units only through redemption. With respect to
redemption requests in excess of $100,000, the Sponsor may determine in its
sole discretion to direct the Trustee to redeem units "in kind" by
distributing Securities to the redeeming Unitholder as directed by the
Sponsor. (See "Redemption".)

TRUST

   The Trust is one of a series of similar but separate unit investment
<F1>
trusts created by the Sponsor pursuant to a Trust Indenture and Agreement*
(the "Indenture") dated as of the Initial Date of Deposit, among PaineWebber
Incorporated, as Sponsor and the Investors Bank & Trust Company and The First
National Bank of Chicago, as Co-Trustees (the "Co-Trustees" or "Trustee"). The
objective of the Trust is preservation of capital and capital appreciation
through an investment in Treasury Obligations and Stocks. These are equity
stocks, which, in Sponsor's opinion on the Date of Deposit, are capable of,
over the long term, closely tracking the performance of the market as measured
by the S&P 500. The Stocks contained in the Trust are representative of a
number of different industries. Dividends, if any, received will be held by the
Trustee in non-interest bearing accounts until used to pay expenses or
distributed to Unitholders on the next Distribution Date and to the extent that
funds are held therein will benefit the Trustee.

   On the Initial Date of Deposit, the Sponsor deposited with the Trustee the
confirmations of contracts for the purchase of Securities together with an
irrevocable letter or letters of credit of a commercial bank or banks in an
amount at least equal to the purchase price. The value of the Securities was
determined on the basis described under "Valuation". In exchange for the
deposit of the contracts to purchase Securities, the Trustee delivered to the
Sponsor a registered certificate for Units representing the entire ownership
of the Trust. On the Initial Date of Deposit the fractional undivided
interest in the Trust represented by a Unit was as set forth in "Essential
Information Regarding the Trust".

   With the deposit on the Initial Date of Deposit, the Sponsor established a
proportionate relationship between the maturity value of the Treasury
Obligations and the number of shares of each Stock in the Trust. The Sponsor
may, from time to time, cause the deposit of additional Securities in the
Trust when additional Units are to be offered to the public, maintaining,
exactly, the original percentage relationship between the maturity value of
the Treasury Obligations and the number of shares of Stock deposited on the
Initial Date of Deposit and replicating any cash or cash equivalents held by
the Trust (net of expenses). The original proportionate relationship is
subject to adjustment to reflect the occurrence of a stock split or a similar
event which affects the capital structure of the issuer of a Stock but which
does not affect the Trust's percentage ownership of the common stock equity
of such issuer at the time of such event. Stock dividends received by the
Trust, if any, will be sold by the Trustee and the proceeds therefrom shall
be treated as income to the Trust.

   The Treasury Obligations consist of U.S. Treasury obligations which have
been stripped of their unmatured interest coupons or interest coupons
stripped from the U.S. Treasury Obligations. The obligor with respect to the
Treasury Obligations is the United States Government. U.S. Government backed
obligations are considered the safest investment.

- ----------
   * Reference is hereby made to said Trust Indenture and Agreement and any
     statements contained herein are qualified in their entirety by the
     provisions of said Trust Indenture and Agreement.

                                              6



      
<PAGE>

   On the Initial Date of Deposit each Unit represented the fractional
undivided interest in the Securities and net income of the Trust set forth
under "Essential Information Regarding the Trust". However, if additional
Units are issued by the Trust (through the deposit of additional Securities
for purposes of the sale of additional Units), the aggregate value of
Securities in the Trust will be increased and the fractional undivided
interest represented by each Unit in the balance will be decreased. If any
Units are redeemed, the aggregate value of Securities in the Trust will be
reduced, and the fractional undivided interest represented by each remaining
Unit in the balance will be increased. Units will remain outstanding until
redeemed upon tender to the Trustee by any Unitholder (which may include the
Sponsor) or until the termination of the Trust. (See "Termination of the
Trust".)

RISK FACTORS AND SPECIAL CONSIDERATIONS

 Risk Factors

   An investment in the Trust should be made with the understanding of the
risks inherent in an investment in deep discount or "zero-coupon" debt
obligations and the risks associated with an investment in common stocks in
general.

   The Trust contains stripped Treasury Securities described below (see
"Schedule of Investments"). Stripped Treasury Securities consist of
"interest-only" or "principal-only" portions of Treasury Obligations.
Interest-only portions of Treasury Obligations represent the rights only to
payment of interest on a date certain, and principal-only portions of
Treasury Obligations represent the rights only to payment of principal at a
stated maturity. Interest-only and principal-only portions of Treasury
Obligations are deep discount obligations that are economically identical to
zero-coupon obligations; that is, all such instruments are debt obligations
which make no periodic payment of interest prior to maturity. THE STRIPPED
TREASURY SECURITIES IN THE TRUST WERE PURCHASED AT A DEEP DISCOUNT AND DO NOT
MAKE ANY PERIODIC PAYMENTS OF INTEREST. Instead, the entire payment of
proceeds will be made upon maturity of such Treasury Obligations. The effect
of owning deep discount bonds which do not make current interest payments
(such as the stripped Treasury Obligations in the Trust Portfolio) is that a
fixed yield is earned not only on the original investment but also, in
effect, on all earned discount during the life of the discount obligation.
This implicit reinvestment of earnings at the same rate eliminates the risk
of being unable to reinvest the income on such obligations at a rate as high
as the implicit yield on the discount obligation, but at the same time
eliminates the holder's ability to reinvest at higher rates in the future.
For this reason, while the full faith and credit of the United States
government provides a high degree of protection against credit risks, sale of
Units prior to the termination date of the Trust will involve substantially
greater price fluctuations during periods of changing market interest rates
than would be experienced in connection with sale of Units of a Trust which
held Treasury Obligations which made scheduled interest payments on a current
basis.

   An investment in Units of the Trust should also be made with an
understanding of the risks inherent in an investment in common stocks in
general. The general risks are associated with the rights to receive payments
from the issuer which are generally inferior to creditors of, or holders of
debt obligations or preferred stocks issued by, the issuer. Holders of common
stocks have a right to receive dividends only when and if, and in the
amounts, declared by the issuer's board of directors and to participate in
amounts available for distribution by the issuer only after all other claims
against the issuer have been paid or provided for. By contrast, holders of
preferred stocks have the right to receive dividends at a fixed rate when and
as declared by the issuer's board of directors, normally on a cumulative
basis, but do not participate in other amounts available for distribution by
the issuing corporation. Dividends on cumulative preferred stock must be paid
before any dividends are paid on common stock. Preferred stocks

                                7



      
<PAGE>

are also entitled to rights on liquidation which are senior to those of
common stocks. For these reasons, preferred stocks generally entail less risk
than common stocks.

   Common stocks do not represent an obligation of the issuer. Therefore they
do not offer any assurance of income or provide the degree of protection of
debt securities. The issuance of debt securities or even preferred stock by
an issuer will create prior claims for payment of principal, interest and
dividends which could adversely affect the ability and inclination of the
issuer to declare or pay dividends on its common stock or the rights of
holders of common stock with respect to assets of the issuer upon liquidation
or bankruptcy. Unlike debt securities which typically have a stated principal
amount payable at maturity common stocks do not have a fixed principal amount
or a maturity. Additionally, the value of the Stocks, like the Treasury
Obligations, in the Trust may be expected to fluctuate over the life of the
Trust to values higher or lower than those prevailing on the Date of Deposit.
The Stocks may appreciate or depreciate in value (or pay dividends) depending
on the full range of economic and market influences affecting corporate
profitability, the financial condition of issuers and the prices of equity
securities in general and the Stocks in particular.

   There is no assurance that the Trust's objective will be achieved. Until
distributed, dividends and principal received upon the sale of Stocks may be
reinvested, until the next applicable distribution date, in current
interest-bearing United States Treasury Obligations. (See "Administration of
the Trust--Reinvestment".) (The Treasury Obligations, the current
interest-bearing United States Treasury Obligations if any, and the Stocks
may be collectively referred to as "Securities" herein.) The value of the
Securities and, therefore, the value of Units may be expected to fluctuate.

   
   Investors should note that the creation of additional Units subsequent to
the Initial Date of Deposit may have an effect upon the value of previously
existing Units. To create additional Units the Sponsor may deposit cash (or
cash equivalents, e.g., a bank letter of credit in lieu of cash) with
instructions to purchase Securities in amounts sufficient to maintain, to the
extent practicable, the percentage relationship among the Securities based on
the price of the Securities at the Evaluation Time on the date the cash is
deposited. To the extent the price of a Security increases or decreases
between the time cash is deposited with instructions to purchase the Security
and the time the cash is used to purchase the Security, Units will represent
less or more of that Security and more or less of the other Securities in the
Trust. Unitholders will be at risk because of price fluctuations during this
period since if the price of shares of a Security increases, Unitholders will
have an interest in fewer shares of that Security, and if the price of a
Security decreases, Unitholders will have an interest in more shares of that
Security, than if the Security had been purchased on the date cash was
deposited with instructions to purchase the Security. In order to minimize
these effects, the Trust will attempt to purchase Securities as close as
possible to the Evaluation Time or at prices as close as possible to the
prices used to evaluate the Trust at the Evaluation Time. Thus price
fluctuations during this period will affect the value of every Unitholder's
Units and the income per Unit received by the Trust. In addition, costs
incurred in connection with the acquisition of Securities not listed on any
national securities exchange (due to differentials between bid and offer
prices for the Securities) and brokerage fees, stamp taxes and other costs
incurred in purchasing stocks will be at the expense of the Trust and will
affect the value of every Unitholder's Units.

   BECAUSE THE TRUST IS ORGANIZED AS A UNIT INVESTMENT TRUST, RATHER THAN AS
A MANAGEMENT INVESTMENT COMPANY, THE TRUSTEE AND THE SPONSOR DO NOT HAVE
AUTHORITY TO MANAGE THE TRUST'S ASSETS FULLY IN AN ATTEMPT TO TAKE ADVANTAGE
OF VARIOUS MARKET CONDITIONS TO IMPROVE THE TRUST'S NET ASSET VALUE, BUT MAY
DISPOSE OF SECURITIES ONLY UNDER LIMITED CIRCUMSTANCES. (SEE "ADMINISTRATION
OF THE TRUST--PORTFOLIO SUPERVISION".)

FEDERAL INCOME TAXES

   In the opinion of Orrick, Herrington & Sutcliffe, counsel for the Sponsor,
under existing law:

       1. The Trust is not an association taxable as a corporation for
    federal income tax purposes. Under the Internal Revenue Code of 1986, as
    amended (the "Code"), each Unitholder will be treated as the owner of a
    pro rata portion of the Trust, and income of the Trust will be treated as
    income of the Unitholder.

       2. Each Unitholder will have a taxable event when the Trust disposes
    of a Security (whether by sale, exchange, redemption, or payment at
    maturity) or when the Unitholder sells its Units or redeems its Units for
    cash. The total tax cost of each Unit to a Unitholder is allocated among
    each of the Securities in accordance with the proportion of the Trust
    comprised by each Security to determine the per Unit tax cost for each
    Security.

       3. The Trust is not an association taxable as a corporation for New
    York State income tax purposes. Under New York State law, each Unitholder
    will be treated as the owner of a pro rata portion of the Trust and the
    income of the Trust will be treated as income of the Unitholders.

   The following general discussion of the federal income tax treatment of an
investment in Units of the Trust is based on the Code and Treasury
regulations promulgated thereunder as in effect on the date of this
Prospectus. The federal income tax treatment applicable to a Unitholder may
depend upon the Unitholder's particular tax circumstances. Future
legislative, judicial or administrative changes could modify the statements
below and could affect the tax consequences to Unitholders. Accordingly, each
Unitholder is advised to consult its own tax advisor concerning the effect of
an investment in Units.

   General. Each Unitholder must report on its federal income tax return a
pro rata share of the entire income of the Trust, derived from dividends on
Stocks, original issue discount or interest on Treasury Obligations, gains or
losses upon sales of Securities by the Trust and a pro rata share of the
expenses of the Trust. Unitholders should note that their taxable income from
an investment in Units will exceed cash distributions because taxable income
will include accretions of original issue discount on the Treasury
Obligations, as well as amounts that are not distributed to Unitholders but
are used by the Trust to pay expenses.

   Distributions with respect to Stock, to the extent they do not exceed
current or accumulated earnings and profits of the distributing corporation,
will be treated as dividends to the Unitholders and will be subject to income
tax at ordinary rates. Corporate Unitholders may be entitled to the
dividends-received deduction discussed below.

   To the extent distributions with respect to a Stock were to exceed the
issuing corporation's current and accumulated earnings and profits, they
would not constitute dividends. Rather, they would be treated as a tax free
return of capital and would reduce a Unitholder's tax cost for such Stock.
After such tax cost

                               10



      
<PAGE>

has been reduced to zero, any additional distributions in excess of current
and accumulated earnings and profits would be taxable as gain from sale of
common stock. This reduction in basis would increase any gain, or reduce any
loss, realized by the Unitholder on any subsequent sale or other disposition
of Units.

   A Unitholder who is an individual, estate or trust may be disallowed
certain itemized deductions described in Code section 67, including
compensation paid to the Trustee and administrative expenses of the Trust, to
the extent these itemized deductions, in the aggregate, do not exceed two
percent of the Unitholder's adjusted gross income. Thus, a Unitholder's
taxable income from an investment in Units will exceed amounts distributed
because taxable income would include amounts that are not distributed to
Unitholders but are used by the Trust to pay expenses.

   Corporate Dividends-Received Deduction. Corporate holders of Units may be
eligible for the dividends-received deduction with respect to distributions
treated as dividends, subject to the limitations provided in Section 246 and
246A of the Code. The dividends-received deduction generally equals 70
percent of the amount of the dividend. As a result, the maximum effective tax
rate on dividends received generally will be reduced from 35 percent to 10.5
percent. A portion of the dividends-received deduction may, however, be
subject to the alternative minimum tax. Individuals, partnerships, trusts, S
corporations and certain other entities are not eligible for the
dividends-received deduction.

   Original Issue Discount. The Trust will contain principal or interest
portions of stripped "zero-coupon" United States Treasury Obligations which
are treated as bonds that were originally issued at a discount ("original
issue discount"). Original issue discount represents interest for federal
income tax purposes and can generally be defined as the difference between
the price at which a bond was issued and its stated redemption price at
maturity. For purposes of the preceding sentence, stripped obligations, such
as the Treasury Obligations, which variously consist either of the right to
receive payments of interest or the right to receive payments of principal,
are treated by each successive purchaser as originally issued on their
purchase dates at an issue price equal to their respective purchase prices
thereof. The market value of the Trust assets comprising the Trust will be
provided to a Unitholder upon request in order to enable the Unitholder to
calculate the original issue discount attributable to each of the Treasury
Obligations. Original issue discount on Treasury Obligations (which were
issued or treated as issued on or after July 2, 1982) is deemed earned in a
geometric progression over the life of such obligation, taking into account
the compounding of accrued interest at least annually, resulting in an
increasing amount of income in each year. Each Unitholder is required to
include in income each year the amount of original issue discount which
accrues on its pro rata portion of each Treasury Obligation with original
issue discount. The amount of accrued original issue discount included in
income with respect to a Unitholder's pro rata interest in Treasury
Obligations is thereupon added to the tax cost for such obligations.

   Gain or Loss on Sale. If a Unitholder sells or otherwise disposes of a
Unit, the Unitholder generally will recognize gain or loss in an amount equal
to the difference between the amount realized on the disposition allocable to
the Securities and the Unitholder's adjusted tax bases in the Securities. In
general, such adjusted tax bases will equal the Unitholder's aggregate cost
for the Unit increased by any accrued original issue discount. Such gain or
loss will be capital gain or loss if the Unit and underlying Securities were
held as capital assets, except that such gain will be treated as ordinary
income to the extent of any accrued original issue discount not previously
reported. Each Unitholder generally will also recognize taxable gain or loss
when all or part of its pro rata portion of a Security is sold or otherwise
disposed of for an amount greater or less than its per Unit tax cost
therefor.

   Withholding For Citizen or Resident Investors. In the case of any
noncorporate Unitholder that is a citizen or resident of the United States a
31 percent "backup" withholding tax will apply to certain distributions of
the Trust unless the Unitholder properly completes and files, under penalties
of perjury, IRS Form W-9 (or its equivalent).

                               11



      
<PAGE>

   The foregoing discussion is a general summary and relates only to certain
aspects of the federal income tax consequences of an investment in the Trust.
Unitholders may also be subject to state and local taxation. Each Unitholder
should consult its own tax advisor regarding the federal, state and local tax
consequences to it of ownership of Units.

   Investment in the Trust may be suited for purchase by funds and accounts
of individual investors that are exempt from federal income taxes such as
Individual Retirement Accounts, tax-qualified retirement plans including
Keogh Plans, and other tax-deferred retirement plans. Unitholders desiring to
purchase Units for tax-deferred plans and IRA's should consult their
PaineWebber Investment Executive for details on establishing such accounts.
Units may also be purchased by persons who already have self-directed
accounts established under tax-deferred retirement plans.

PUBLIC OFFERING OF UNITS

   
   Public Offering Price. The public offering price per Unit on the Initial
Date of Deposit is equal to the aggregate market value of the Securities
determined on the day preceding the Initial Date of Deposit, divided by the
number of Units outstanding plus the sales charge of 4.75%, pursuant to an
exemptive order of the SEC. However, if the price would be less than $.97 1/2
then purchase orders received that day will be filled on the basis of the
lower public offering price. Thereafter, the public offering price during the
initial offering period will be computed by dividing the Trust Fund
Evaluation, next determined after receipt of a purchase order, and, with
respect to the Treasury Obligations, determined with reference to the
offering side evaluation, by the number of Units outstanding plus the
applicable sales charge. The initial public offering period will terminate
when the Sponsor chooses to discontinue offering Units in the initial market.
Thereafter, the Sponsor may offer Units in the secondary market. The public
offering price in the secondary market will be the Trust Fund Evaluation per
Unit next determined after receipt of a purchase order, determined with
respect to the Treasury Obligations on the bid side of the market, plus the
applicable sales charge. (See "Valuation".) The public offering price on any
date subsequent to the Initial Date of Deposit will vary from the public
offering price calculated on the business day prior to the Initial Date of
Deposit (as set forth on page 2 hereof) due to fluctuations in the value of
Stocks and the Treasury Obligations.
    

   Sales Charge and Volume Discount. Sales charges during the initial public
offering period and for secondary market sales are set forth below. A
discount in the sales charge is available to volume purchasers of Units due
to economies of scales in sales effort and sales related expenses relating to
volume purchases. The sales charge applicable to volume purchasers of Units
is reduced on a graduated scale for sales to any person of at least $50,000
or 50,000 Units, applied on whichever basis is more favorable to the
purchaser.

   The volume discount sales charge shown above will apply to all purchases
of Units on any one day by the same person in the amounts stated herein, and
for this purpose purchases of Units of this Trust will be aggregated with
concurrent purchases of any other trust which may be offered by the Sponsor.
Units held in the name of the purchaser's spouse or in the name of a
purchaser's child under the age of 21 are deemed for the purposes hereof to
be registered in the name of the purchaser. The reduced sales charges are
also applicable to a trustee or other fiduciary purchasing Units for a single
trust estate or single fiduciary account.

   Employee Discount. Due to the realization of economies of scale in sales
effort and sales related expenses with respect to the purchase of Units by
employees of the Sponsor and its affiliates, the Sponsor intends to permit
employees of the Sponsor and its affiliates and certain of their relatives to
purchase units of the Trust at a reduced sales charge of $5.00 per 1,000
Units.

   Exchange Option. Unitholders may elect to exchange any or all of their
Units of this series for units of one or more of any series of PaineWebber
Municipal Bond Fund (the "PaineWebber Series"); The Municipal Bond Trust (the
"National Series"); The Municipal Bond Trust, Multi-State Program (the
"Multi-State Series"); The Municipal Bond Trust, California Series (the
"California Series"); The Corporate Bond Trust (the "Corporate Series");
PaineWebber Pathfinder's Trust (the "Pathfinder's Trust"); the PaineWebber
Federal Government Trust (the "Government Series"); The Municipal Bond Trust,
Insured Series (the "Insured Series"); or the PaineWebber Equity Trust (the
"Equity Series") (collectively referred to as the "Exchange Trusts"), at a
Public Offering Price for the Units of the Exchange Trusts to be acquired
based on a reduced sales charge of $15 per Unit, per 100 Units in the case of
a trust whose Units cost approximately $10 or per 1,000 units in the case of
a trust whose Units cost approximately one dollar. Unitholders of this Trust
are not eligible for the Exchange Option into an Equity Trust, Growth Stock
Series designated as a rollover series for the 30 day period prior to
termination of the Trust. The purpose of such reduced sales charge is to
permit the Sponsor to pass on to the Unitholder who wishes to exchange Units
the cost savings resulting from such exchange of Units. The cost savings
result from reductions in time and expense related to advice, financial
planning and operational expenses required for the Exchange Option. Each
Exchange Trust has different investment objectives, therefore a Unitholder
should read the prospectus for the applicable exchange trust carefully prior
to exercising this option. Exchange Trusts having as their objective the
receipt of tax-exempt interest income would not be suitable for tax-deferred
investment plans such as Individual Retirement Accounts. A Unitholder who
purchased Units of a series and paid a per Unit, per 100 Unit or per 1,000
Unit sales charge that was less than the per Unit, per 100 Unit or per 1,000
Unit sales charge of the series of the Exchange Trusts for which such
Unitholder desires to exchange into, will be allowed to exercise the Exchange
Option at the Unit Offering Price plus the reduced sales charge, provided the
Unitholder has held the Units for at least five months. Any such Unitholder
who has not held the Units to be exchanged for the five-month period will be
required to exchange them at the Unit Offering Price plus a sales charge
based on the greater of the reduced sales charge, or an amount which,
together with the initial sales charge paid in connection with the
acquisition of the Units being exchanged, equals the sales charge of the
series of the Exchange Trust for which such Unitholder desires to exchange
into, determined as of the date of the exchange.

   The Sponsor will permit exchanges at the reduced sales charge provided
there is either a primary market for Units or a secondary market maintained
by the Sponsor in both the Units of this series and units of the applicable
Exchange Trust and there are units of the applicable Exchange Trust available
for sale. While the Sponsor has indicated that it intends to maintain a
market for the Units of the respective Trusts, there is no obligation on its
part to maintain such a market. Therefore, there is no assurance that

                               14



      
<PAGE>

   
a market for Units will in fact exist on any given date at which a Unitholder
wishes to sell his Units of this series and thus there is no assurance that
the Exchange Option will be available to a Unitholder. Exchanges will be
effected in whole Units only. Any excess proceeds from Unitholders' Units
being surrendered will be returned. Unitholders will be permitted to advance
new money in order to complete an exchange to round up to the next highest
number of Units. An exchange of Units pursuant to the Exchange Option will
normally constitute a "taxable event" under the Code and a Unitholder will
generally recognize a tax gain or loss at the time of exchange in the same
manner as upon a sale of Units. Unitholders are urged to consult their own
tax advisors as to the tax consequences to them of exchanging Units in
particular cases.
    

   The Sponsor reserves the right to modify, suspend or terminate this
Exchange Option at any time without further notice to Unitholders. In the
event the Exchange Option is not available to a Unitholder at the time he
wishes to exercise it, the Unitholder will be immediately notified and no
action will be taken with respect to his Units without further instruction
from the Unitholder.

   To exercise the Exchange Option, a Unitholder should notify the Sponsor of
his desire to exercise the Exchange Option and to use the proceeds from the
sale of his Units to the Sponsor of this series to purchase Units of one or
more of the Exchange Trusts from the Sponsor. If Units of the applicable
outstanding series of the Exchange Trust are at that time available for sale,
and if such Units may lawfully be sold in the state in which the Unitholder
is resident, the Unitholder may select the series or group of series for
which he desires his investment to be exchanged. The Unitholder will be
provided with a current prospectus or prospectuses relating to each series in
which he indicates interest.

   The exchange transaction will operate in a manner essentially identical to
any secondary market transaction, i.e., Units will be repurchased at a price
based on the market value of the Securities in the portfolio of the Trust
next determined after receipt by the Sponsor of an exchange request and
properly endorsed Certificate. Units of the Exchange Trust will be sold to
the Unitholder at a price based upon the next determined market value of the
Securities in the Exchange Trust plus the reduced sales charge. Exchange
transactions will be effected only in whole units; thus, any proceeds not
used to acquire whole units will be paid to the selling Unitholder.

   For example, assume that a Unitholder, who has three thousand units of a
trust with a current price of $1.30 per unit, desires to sell his units and
seeks to exchange the proceeds for units of a series of an Exchange Trust
with a current price of $890 per unit based on the bid prices of the
underlying securities. In this example, which does not contemplate any
rounding up to the next highest number of Units, the proceeds from the
Unitholder's units would aggregate $3,900. Since only whole units of an
Exchange Trust may be purchased under the Exchange Option, the Unitholder
would be able to acquire four units in the Exchange Trust for a total cost of
$3,620 ($3,560 for the units and $60 for the sales charge). If all 3,000
units were tendered, the remaining $280 would be returned to the Unitholder.

   Conversion Option. Owners of units of any registered unit investment trust
sponsored by another which was initially offered at a maximum applicable
sales charge of at least 3.0% (a "Conversion Trust") may elect to apply the
cash proceeds of the sale or redemption of those units directly to acquire
available units of any Exchange Trust at a reduced sales charge of $15 per
Unit (or per 100 Units in the case of Exchange Trusts having a Unit price of
approximately $10, or per 1,000 Units in the case of Exchange Trusts having a
Unit price of approximately $1), subject to the terms and conditions
applicable to the Exchange Option (except that no secondary market is
required for Conversion Trust units). To exercise this option, the owner
should notify his retail broker. He will be given a prospectus for each
series in which he indicates interest and for which units are available. The
dealer must sell or redeem the units of the

                               15



      
<PAGE>

Conversion Trust. Any dealer other than PaineWebber must certify that the
purchase of units of the Exchange Trust is being made pursuant to and is
eligible for the Conversion Option. The dealer will be entitled to two thirds
of the applicable reduced sales charge. The Sponsor reserves the right to
modify, suspend or terminate the Conversion Option at any time without
further notice, including the right to increase the reduced sales charge
applicable to this option (but not in excess of $5 more per Unit (or per 100
Units or per 1,000 Units, as applicable) than the corresponding fee then
being charged for the Exchange Option). For a description of the tax
consequences of a conversion reference is made to the Exchange Option section
of the prospectus.

   Distribution of Units. The minimum purchase during the initial public
offering is $1,000, except that the minimum purchase is $250 for purchases
made in connection with Individual Retirement Accounts or other tax-deferred
retirement plans. Only whole Units may be purchased.

   The Sponsor is the sole underwriter of the Units. Sales may, however, be
made to dealers who are members of the National Association of Securities
Dealers, Inc. ("NASD") at prices which include a concession of $.03 per Unit,
during the initial offering period and one-half of the highest applicable
sales charge during the secondary market, subject to change from time to
time. The difference between the sales charge and the dealer concession will
be retained by the Sponsor. In the event that the dealer concession is 90% or
more of the sales charge per Unit, dealers taking advantage of such
concession may be deemed to be underwriters under the Securities Act of 1933.

   The Sponsor reserves the right to reject, in whole or in part, any order
for the purchase of Units. The Sponsor intends to qualify the Units in all
states of the United States, the District of Columbia and the Commonwealth of
Puerto Rico.

   Secondary Market for Units. While not obligated to do so, the Sponsor
intends to maintain a secondary market for the Units and continuously offer
to purchase Units at the Trust Fund Evaluation per Unit next computed after
receipt by the Sponsor of an order from a Unitholder. The Sponsor may cease
to maintain such a market at any time, and from time to time, without notice.
In the event that a secondary market for the Units is not maintained by the
Sponsor, a Unitholder desiring to dispose of Units may tender such Units to
the Trustee for redemption at the price calculated in the manner set forth
under "Redemption". Redemption requests in excess of $100,000 may be redeemed
"in kind" as described under "Redemption." The Sponsor does not in any way
guarantee the enforceability, marketability, value or price of any stocks in
the Trust, nor that of the Units.

   Investors should note the Trust Fund Evaluation per Unit at the time of
sale or tender for redemption may be less than the price at which the Unit
was purchased.

   The Sponsor may redeem any Units it has purchased in the secondary market
if it determines for any reason that it is undesirable to continue to hold
these Units in its inventory. Factors which the Sponsor may consider in
making this determination will include the number of units of all series of
all trusts which it holds in its inventory, the saleability of the Units and
its estimate of the time required to sell the Units and general market
conditions.

   Sponsor's Profits. In addition, to the applicable sales charge, the
Sponsor realizes a profit (or sustains a loss) in the amount of any
difference between the cost of the Securities to the Sponsor and the price at
which it deposits the Securities in the Trust, which is the value of the
Securities, determined by the Trustee as described under "Valuation," at the
close of business on the business day prior to the Date of Deposit. The cost
of Securities to the Sponsor includes the amount paid by the Sponsor for
brokerage commissions. These amounts are an expense of the Trust.

                               16



      
<PAGE>

   Cash, if any, received from Unitholders prior to the settlement date for
the purchase of Units or prior to the payment for Securities upon their
delivery may be used in the Sponsor's business subject to the limitations of
Rule 15c3-3 under the Securities and Exchange Act of 1934 and may be of
benefit to the Sponsor.

   In selling any Units in the initial public offering after the Date of
Deposit, the Sponsor may realize profits or sustain losses resulting from
fluctuations in the net asset value of outstanding Units during that period.
In maintaining a secondary market for the Units, the Sponsor may realize
profits or sustain losses in the amount of any differences between the price
at which it buys Units and the price at which it resells or redeems such
Units.

REDEMPTION

   Units may be tendered to Investors Bank & Trust Company for redemption at
its office in person, or by mail at One Lincoln Plaza, 89 South Street,
Boston, MA 02111 upon payment of any transfer or similar tax which must be
paid to effect the redemption. At the present time there are no such taxes.
No redemption fee will be charged by the Sponsor or the Trustee. If Units are
represented by a certificate, it must be properly endorsed accompanied by a
letter requesting redemption. If held in uncertificated form, a written
instrument of redemption must be signed by the Unitholder. Unitholders must
sign exactly as their names appear on the records of the Trustee with
signatures guaranteed by an eligible guarantor institution or in such other
manner as may be acceptable to the Trustee. In certain instances the Trustee
may require additional documents such as, but not limited to, trust
instruments, certificates of death, appointments as executor or
administrator, or certificates of corporate authority. Unitholders should
contact the Trustee to determine whether additional documents are necessary.
Units tendered to the Trustee for redemption will be cancelled, if not
repurchased by the Sponsor.

   Units will be redeemed at the Redemption Value per Unit next determined
after receipt of the redemption request in good order by the Trustee. The
Redemption Value per Unit is determined by dividing the Trust Fund Evaluation
by the number of Units outstanding. (See "Valuation.")

   
   A redemption request is deemed received on the business day (See
"Valuation" for a definition of business day) when such request is received
prior to 4:00 p.m. If it is received after 4:00 p.m., it is deemed received
on the next business day. During the period in which the Sponsor maintains a
secondary market for Units, the Sponsor may repurchase any Unit presented for
tender to Investors Bank & Trust Company for redemption no later than the
close of business on the second business day following such presentation and
Unitholders will receive the Redemption Value next determined after receipt
by the Trustee of the redemption request. Proceeds of a redemption will be
paid to the Unitholder on the seventh calendar day following the date of
tender (or if the seventh calendar day is not a business day on the first
business day prior thereto).
    

   With respect to cash redemptions, amounts representing income received
shall be withdrawn from the Income Account, and, to the extent such balance
is insufficient, from the Capital Account. The Trustee is empowered, to the
extent necessary, to sell Securities in such manner as is directed by the
Sponsor, which direction shall be given so as to maximize the objectives of
the Trust. In the event that no such direction is given by the Sponsor, the
Trustee is empowered to sell Securities as follows: Treasury Obligations will
be sold so as to maintain in the Trust Treasury Obligations in an amount
which, upon maturity, will equal at least $1.00 per Unit outstanding after
giving effect to such redemption and Stocks having the greatest amount of
capital appreciation will be sold first. (See "Administration of the Trust".)
However, with respect to redemption requests in excess of $100,000, the
Sponsor may determine in its discretion to direct the Trustee to redeem Units
"in kind" by distributing Securities to the redeeming

                               17



      
<PAGE>

Unitholder. When Stock is distributed, a proportionate amount of Stock will
be distributed, rounded to avoid the distribution of fractional shares and
using cash or checks where rounding is not possible. The Sponsor may direct
the Trustee to redeem Units "in kind" even if it is then maintaining a
secondary market in Units of the Trust. Securities will be valued for this
purpose as set forth under "Valuation". A Unitholder receiving a redemption
"in kind" may incur brokerage or other transaction costs in converting the
Securities distributed into cash. The availability of redemption "in-kind" is
subject to compliance with all applicable laws and regulations, including the
Securities Act of 1933, as amended.

   To the extent that Securities are redeemed in kind or sold, the size and
diversity of the Trust will be reduced. Sales will usually be required at a
time when Securities would not otherwise be sold and may result in lower
prices than might otherwise be realized. The price received upon redemption
may be more or less than the amount paid by the Unitholder depending on the
value of the Securities in the portfolio at the time of redemption. In
addition, because of the minimum amounts in which Securities are required to
be sold, the proceeds of sale may exceed the amount required at the time to
redeem Units; these excess proceeds will be distributed to Unitholders on the
Distribution Dates.

   The Trustee may, in its discretion, and will, when so directed by the
Sponsor, suspend the right of redemption, or postpone the date of payment of
the Redemption Value, for more than seven calendar days following the day of
tender for any period during which the New York Stock Exchange, Inc. is
closed other than for weekend and holiday closings; or for any period during
which the Securities and Exchange Commission determined that trading on the
New York Stock Exchange, Inc. is restricted or for any period during which an
emergency exists as a result of which disposal or evaluation of the
Securities is not reasonably practicable; or for such other period as the
Securities and Exchange Commission may by order permit for the protection of
Unitholders. The Trustee is not liable to any person or in any way for any
loss or damages which may result from any such suspension or postponement, or
any failure to suspend or postpone when done in the Trustee's discretion.

VALUATION

   The Trustee will calculate the Trust's value (the "Trust Fund Evaluation")
per Unit at the Valuation Time set forth under "Summary of Essential
Information" (1) on each June 30 and December 31 (or the last business day
prior thereto), (2) on each business day as long as the Sponsor is
maintaining a bid in the secondary market, (3) on the business day on which
any Unit is tendered for redemption and (4) on any other day desired by the
Sponsor or the Trustee, by adding (a) the aggregate value of the Securities
and other assets determined by the Trustee as set forth below, (b) cash on
hand in the Trust, income accrued on the Treasury Obligations but not
distributed or held for distribution and dividends receivable on Stocks
trading ex-dividend (other than any cash held in any reserve account
established under the Indenture) and (c) accounts receivable for securities
sold and any other assets of the Trust Fund not included in (a) and (b) above
and deducting therefrom the sum of (v) taxes or other governmental charges
against the Trust not previously deducted, (w) accrued fees and expenses of
the Trustee and the Sponsor (including legal and auditing expenses) and other
Trust expenses, (x) cash allocated for distribution to Unitholders, and (y)
accounts payable for units tendered for redemption and any other liabilities
of the Trust Fund not included in (v), (w) , (x) and (y) above. The per Unit
Trust Fund Evaluation is calculated by dividing the result of such
computation by the number of Units outstanding as of the date thereof.
Business days do not include New Year's Day, Washington's Birthday, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
Christmas Day and other days that the New York Stock Exchange is closed.

                               18



      
<PAGE>

   The value of Stocks shall be determined by the Trustee in good faith in
the following manner: (1) if the Securities are listed on one or more
national securities exchanges, such evaluation shall be based on the closing
sale price on that day (unless the Trustee deems such price inappropriate as
a basis for evaluation) on the exchange which is the principal market thereof
(deemed to be the New York Stock Exchange if the Securities are listed
thereon) (2) if there is no such appropriate closing sale price on such
exchange, at the mean between the closing bid and asked prices on such
exchange (unless the Trustee deems such price inappropriate as a basis for
evaluation), (3) if the Securities are not so listed or, if so listed and the
principal market therefor is other than on such exchange or there are no such
appropriate closing bid and asked prices available, such evaluation shall be
made by the Trustee in good faith based on the closing sale price on the
over-the-counter market (unless the Trustee deems such price inappropriate as
a basis for evaluation) or (4) if there is no such appropriate closing price,
then (a) on the basis of current bid prices, (b) if bid prices are not
available, on the basis of current bid prices for comparable securities, (c)
by the Trustee's appraising the value of the Securities in good faith on the
bid side of the market or (d) by any combination thereof.

   During the initial offering period the Treasury Obligations are valued on
the basis of offering prices; thereafter and for purposes of determining
Redemption Value they are valued on the basis of bid prices. The aggregate
offering and bid prices of the Treasury Obligations, is the price obtained
from investment dealers or brokers (which may include the Sponsor) who
customarily deal in Treasury Obligations; or, if there is no market for the
Treasury Obligations, and bid or offering prices are not available, on the
basis of current bid or offering prices for comparable securities; or by
appraisal; or by any combination of the above, adjusted to reflect income
accrued.

COMPARISON OF PUBLIC OFFERING PRICE AND REDEMPTION VALUE

   While the Public Offering Price of Units during the initial offering
period is determined on the basis of the current offering prices of the
Treasury Obligations, the Public Offering Price of Units in the secondary
market and the Redemption Value is determined on the basis of the current bid
prices of the Treasury Obligations. The Stocks are valued on the same basis
for the initial and secondary markets and for purposes of redemptions. On the
business day prior to the Date of Deposit, the Public Offering Price per Unit
(which figure includes the sales charge) exceeded the Redemption Value, (see:
"Essential Information"). The bid and offering prices of the Treasury
Obligations is expected to vary. For this reason and others, including the
fact that the Public Offering Price includes the sales charge, the amount
realized by a Unitholder upon redemption of Units may be less than the price
paid by the Unitholder for such Units.

EXPENSES OF THE TRUST

   The cost of the preparation and printing of the Certificates, the
Indenture and this Prospectus, the initial fees of the Trustee and the
Trustee's counsel, advertising expenses and expenses incurred in establishing
the Trust including legal and auditing fees, are paid by the Sponsor and not
by the Trust. The Sponsor will receive no fee from the Trust for its services
as Sponsor.

   The Sponsor will receive a fee, which is earned for portfolio supervisory
services, and which is based upon the largest number of Units outstanding
during the calendar year. The Sponsor's fee, which is initially $.00035 per
Unit, may exceed the actual costs of providing portfolio supervisory services
for the Trust, but at no time will the total amount it receives for portfolio
supervisory services rendered to all series of the PaineWebber Pathfinders
Trust in any calendar year exceed the aggregate cost to it of supplying such
services in such year.

                               19



      
<PAGE>

   
   For its services as Trustee and Evaluator, the Trustee will be paid in
monthly installments, annually $.00145 per Unit computed monthly based upon
the largest number of Units outstanding in the Trust during the preceding
month. In addition, the regular and recurring expenses of the Trust are
estimated to be $.00055 per Unit annually which include, but are not limited
to certain mailing, printing, and audit expenses. Expenses in excess of this
estimate will be borne by the Trust. The Trustee could also benefit to the
extent that it may hold funds in non-interest bearing accounts created by the
Indenture.
    

   The Sponsor's fee and Trustee's fee may be increased without approval of
the Unitholders by an amount not exceeding a proportionate increase in the
category entitled "All Services Less Rent" in the Consumer Price Index
published by the United States Department of Labor or if the Price Index is
no longer published, a similar index as determined by the Trustee and
Sponsor.

   In addition to the above, the following charges are or may be incurred by
each Trust and paid from the Income Account, or, to the extent funds are not
available in such Account, from the Capital Account (see "Administration of
the Trust-Accounts"): (1) fees for the Trustee for extraordinary services;
(2) expenses of the Trustee (including legal and auditing expenses) and of
counsel; (3) various governmental charges; (4) expenses and costs of any
action taken by the Trustee to protect the trusts and the rights and
interests of the Unitholders; (5) indemnification of the Trustee for any
loss, liabilities or expenses incurred by it in the administration of the
Trust without gross negligence, bad faith or wilful misconduct on its part;
(6) brokerage commissions and other expenses incurred in connection with the
purchase and sale of Securities; and (7) expenses incurred upon termination
of the Trust. In addition, to the extent then permitted by the Securities and
Exchange Commission, the Trust may incur expenses of maintaining registration
or qualification of the Trust or the Units under Federal or state securities
laws so long as the Sponsor is maintaining a secondary market (including, but
not limited to, legal, auditing and printing expenses).

   The accounts of the Trust shall be audited not less than annually by
independent public accountants selected by the Sponsor. The expenses of the
audit shall be an expense of the Trust. So long as the Sponsor maintains a
secondary market, the Sponsor will bear any audit expense which exceeds
$.00050 per Unit. Unitholders covered by the audit during the year may
receive a copy of the audited financials upon request.

   The fees and expenses set forth above are payable out of the Trust and
when unpaid will be secured by a lien on the Trust. Based upon the last
dividend paid prior to the Initial Date of Deposit, dividends on the Stocks
are expected to be sufficient to pay the estimated expenses of the Trust. To
the extent that dividends paid with respect to the Stocks are not sufficient
to meet the expenses of the Trust, the Trustee is authorized to sell
Securities in the same manner as provided in "Redemption" herein.

RIGHTS OF UNITHOLDERS

   Ownership of Units is evidenced by recordation on the books of the
Trustee. In order to avoid additional operating costs and for investor
convenience, certificates will not be issued unless a request, in writing
with signature guaranteed by an eligible guarantor institution or in such
other manner as may be acceptable to the Trustee, is delivered by the
Unitholder to the Sponsor. Issued Certificates are transferable by
presentation and surrender to the Trustee at its office in Boston,
Massachusetts properly endorsed or accompanied by a written instrument or
instruments of transfer. Uncertificated Units are transferable by
presentation to the Trustee at its office of a written instrument of
transfer.

   Certificates may be issued in denominations of one Unit or any integral
multiple thereof as deemed appropriate by the Trustee. A Unitholder may be
required to pay $2.00 per certificate reissued or transferred, and shall be
required to pay any governmental charge that may be imposed in connection
with each such transfer or interchange. For new certificates issued to
replace destroyed, mutilated, stolen

                               20



      
<PAGE>

   
or lost certificates, the Unitholder must furnish indemnity satisfactory to
the Trustee and must pay such expenses as the Trustee may incur. Mutilated
certificates must be surrendered to Investors Bank & Trust Company for
replacement.
    

DISTRIBUTIONS

   The Trustee will distribute any net income and principal received
quarterly on the Distribution Dates to Unitholders of record on the preceding
Record Date. Income with respect to the original issue discount on the
Treasury Obligations will not be distributed although Unitholders will be
subject to tax as if a distribution had occurred. See "Federal Income Taxes".

   Within a reasonable period after the Trust is terminated, each Unitholder
will, upon surrender of his Certificates for cancellation, receive his pro
rata share of the amounts realized upon disposition of the Securities plus
any other assets of the Trust, less expenses of the Trust. (See
"Termination.")

ADMINISTRATION OF THE TRUST

   Accounts. All dividends received and interest, if any, accrued on
Securities, proceeds from the sale of Securities or other monies received by
the Trustee on behalf of the Trust shall be held in trust in non-interest
bearing accounts until required to be disbursed.

   The Trustee will credit on its books to an Income Account any dividends
(including stock dividends which were sold) and interest, if any, accrued by
the Trust. All other receipts (i.e. return of principal, and gains) are
credited on its books to a Capital Account. Stock dividends received by the
Trust, if any, will be sold by the Trustee and the proceeds therefrom be
treated as income to the Trust. A record will be kept of qualifying dividends
within the Income Account. The pro rata share of the Income Account and the
pro rata share of the Capital Account represented by each Unit will be
computed by the Trustee as set forth under "Valuation".

   The Trustee will deduct from the Income Account and, to the extent funds
are not sufficient therein, from the Capital Account, amounts necessary to
pay expenses incurred by the Trust. (See "Expenses and Charges.") In
addition, the Trustee may withdraw from the Income Account and the Capital
Account such amounts as may be necessary to cover redemption of Units by the
Trustee. (See "Redemption.")

   The Trustee may establish reserves (the "Reserve Account") within the
Trust for state and local taxes, if any, and any other governmental charges
payable out of the Trust.

   Reports and Records. With the distribution of income from the Trust,
Unitholders will be furnished with a statement setting forth the amount being
distributed from each account.

   The Trustee keeps records and accounts of the Trust at its office in
Boston, including records of the names and addresses of Unitholders, a
current list of underlying Securities in the portfolio and a copy of the
Indenture. Records pertaining to a Unitholder or to the Trust (but not to
other Unitholders) are available to the Unitholder for inspection at
reasonable times during business hours.

   
   Within a reasonable period of time after the end of each calendar year,
starting with calendar year 1995, the Trustee will furnish each person who
was a Unitholder at any time during the calendar year an annual report
containing the following information, expressed in reasonable detail both as
a dollar amount and as a dollar amount per Unit: (1) a summary of
transactions for such year in the Income and Capital Accounts and any
Reserves; (2) any Securities sold during the year and the Securities held at
the end of such year; (3) the Trust Fund Evaluation per Unit, based upon a
computation thereof on the 31st day of December of such year (or the last
business day prior thereto); and (4) amounts distributed to Unitholders
during such year.
    

                               21



      
<PAGE>

   Portfolio Supervision. The portfolio of the Trust is not "managed" by the
Sponsor or the Trustee; their activities described herein are governed solely
by the provisions of the Indenture. The Indenture provides that the Sponsor
may (but need not) direct the Trustee to dispose of a Security:

       (1) upon the failure of the issuer to declare or pay anticipated
    dividends or interest;

       (2) upon the institution of materially adverse action or proceeding
    at law or in equity seeking to restrain or enjoin the declaration or
    payment of dividends or interest on any such Securities or the existence
    of any other materially adverse legal question or impediment affecting
    such Securities or the declaration or payment of dividends or interest on
    the same;

       (3) upon the breach of covenant or warranty in any trust indenture or
    other document relating to the issuer which might materially and
    adversely affect either immediately or contingently the declaration or
    payment of dividends or interest on such Securities;

       (4) upon the default in the payment of principal or par or stated
    value of, premium, if any, or income on any other outstanding securities
    of the issuer or the guarantor of such securities which might materially
    and adversely, either immediately or contingently, affect the declaration
    or payment of dividends or interest on the Securities;

       (5) upon the decline in price or the occurrence of any materially
    adverse market or credit factors, that in the opinion of the Sponsor,
    make the retention of such Securities not in the best interest of the
    Unitholder;

       (6) upon a public tender offer being made for a Security, or a merger
    or acquisition being announced affecting a Security that in the opinion
    of the Sponsor make the sale or tender of the Security in the best
    interests of the Unitholders;

       (7) upon a decrease in the Sponsor's internal rating of the Security;
    or

       (8) upon the happening of events which, in the opinion of the
    Sponsor, negatively affect the economic fundamentals of the issuer of the
    Security or the industry of which it is a part.

   The Trustee may dispose of Securities where necessary to pay Trust
expenses or to satisfy redemption requests as directed by the Sponsor and in
a manner necessary to maximize the objectives of the Trust, or if not so
directed in its own discretion, provided however, that Treasury Obligations
will be sold so as to maintain in the Trust Treasury Obligations in an amount
which, upon maturity, will equal at least $1.00 per Unit outstanding after
giving effect to such redemption and Stocks having the greatest appreciation
shall be sold first.
   
   Reinvestment. Cash received upon the sale of Stock (except for sales to
meet redemption requests) and dividends received may, if and to the extent
there is no legal or regulatory impediment, be reinvested in United States
Treasury obligations which mature on or prior to the next scheduled
Distribution Date. The Sponsor anticipates that, where permitted, such proceeds
will be reinvested in current interest-bearing United States Treasury
obligations unless factors exist such that such reinvestment would not be in
the best interest of Unitholders or would be impractical. Such factors may
include, among others, (i) short reinvestment periods which would make
reinvestment in United States Treasury obligations undesirable or infeasible
and (ii) amounts not sufficiently large so as to make a reinvestment economical
or feasible. Any moneys held and not reinvested will be held in a non-interest
bearing account until distribution on the next Distribution Date to Unitholders
of record.
    
                               22



      
<PAGE>

AMENDMENT OF THE INDENTURE

   The Indenture may be amended by the Trustee and the Sponsor without the
consent of any of the Unitholders to cure any ambiguity or to correct or
supplement any provision thereof which may be defective or inconsistent or to
make such other provisions as will not materially adversely affect the
interest of the Unitholders.

   The Indenture may be amended in any respect by the Sponsor and the Trustee
with the consent of the holders of 51% of the Units then outstanding;
provided that no such amendment shall (1) reduce the interest in the Trust
represented by a Unit or (2) reduce the percentage of Unitholders required to
consent to any such amendment, without the consent of all Unitholders.

   The Trustee will promptly notify Unitholders of the substance of any
amendment affecting Unitholders rights or their interest in the Trust.

TERMINATION OF THE TRUST

   The Indenture provides that the Trust will terminate within 15 days after
the maturity of the Treasury Obligations held in the Trust. If the value of
the Trust as shown by any evaluation is less than twenty percent (20%) of the
market value of the Securities on the Date of Deposit, the Trustee may in its
discretion, and will when so directed by the Sponsor, terminate such Trust.
The Trust may also be terminated at any time by the written consent of 51% of
the Unitholders or by the Trustee upon the resignation or removal of the
Sponsor if the Trustee determines termination to be in the best interest of
the Unitholders. In no event will the Trust continue beyond the Mandatory
Termination Date.

   As directed by the Sponsor approximately 30 days prior to the maturity of
the Treasury Obligations the Trustee will begin to sell the Stocks held in
the Trust. Stocks having the greatest amount of capital appreciation will be
sold first. Upon termination of the Trust, the Trustee will sell any Stocks
then remaining in the Trust and will then, after deduction of any fees and
expenses of the Trust and payment into the Reserve Account of any amount
required for taxes or other governmental charges that may be payable by the
Trust, distribute to each Unitholder, upon surrender for cancellation of his
Certificate after due notice of such termination, such Unitholder's pro rata
share in the Income and Capital Accounts. Monies held upon the sale of
Securities will be held in non-interest bearing accounts created by the
Indenture until distributed and will be of benefit to the Trustee. The sale
of Stocks in the Trust in the period prior to termination and upon
termination may result in a lower amount than might otherwise be realized if
such sale were not required at such time due to impending or actual
termination of the Trust. For this reason, among others, the amount realized
by a Unitholder upon termination may be less than the amount paid by such
Unitholder.

SPONSOR

   The Sponsor, PaineWebber Incorporated, is a corporation organized under
the laws of the State of Delaware. The Sponsor is a member firm of the New
York Stock Exchange, Inc. as well as other major securities and commodities
exchanges and is a member of the National Association of Securities Dealers,
Inc. The Sponsor is engaged in a security and commodity brokerage business as
well as underwriting and distributing new issues. The Sponsor also acts as a
dealer in unlisted securities and municipal bonds and in addition to
participating as a member of various selling groups or as an agent of other
investment companies, executes orders on behalf of investment companies for
the purchase and sale of securities of such companies and sells securities to
such companies in its capacity as a broker or dealer in securities.

                               23



      
<PAGE>

   The Indenture provides that the Sponsor will not be liable to the Trustee,
any of the Trusts or to the Unitholders for taking any action or for
refraining from taking any action made in good faith or for errors in
judgment, but will be liable only for its own wilful misfeasance, bad faith,
gross negligence or wilful disregard of its duties. The Sponsor will not be
liable or responsible in any way for depreciation or loss incurred by reason
of the sale of any Securities in the Trust.

   The Indenture is binding upon any successor to the business of the
Sponsor. The Sponsor may transfer all or substantially all of its assets to a
corporation or partnership which carries on the business of the Sponsor and
duly assumes all the obligations of the Sponsor under the Indenture. In such
event the Sponsor shall be relieved of all further liability under the
Indenture.

   If the Sponsor fails to undertake any of its duties under the Indenture,
becomes incapable of acting, becomes bankrupt, or has its affairs taken over
by public authorities, the Trustee may either appoint a successor Sponsor or
Sponsors to serve at rates of compensation determined as provided in the
Indenture or terminate the Indenture and liquidate the Trust.

TRUSTEE

   The Co-Trustees are The First National Bank of Chicago, a national banking
association with its corporate trust office at One First National Plaza,
Suite 0126, Chicago, Illinois 60670-0126 (which is subject to supervision by
the Comptroller of the Currency, the Federal Deposit Insurance Corporation

                        REPORT OF INDEPENDENT AUDITORS

THE UNITHOLDERS, SPONSOR AND CO-TRUSTEES
THE PAINEWEBBER PATHFINDERS TRUST,
TREASURY AND GROWTH STOCK SERIES 16

   
   We have audited the accompanying Statement of Financial Condition of The
PaineWebber Pathfinders Trust, Treasury and Growth Stock Series 16, including
the Schedule of Investments, as of January 24, 1995. This Statement of
Financial Condition is the responsibility of the Co-Trustees. Our
responsibility is to express an opinion on this Statement of Financial
Condition based on our audit.

   We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the Statement of Financial
Condition is free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the Statement
of Financial Condition. Our procedures included confirmation with Investors
Bank & Trust Company, a Co-Trustee, of an irrevocable letter of credit
deposited for the purchase of securities, as shown in the Statement of
Financial Condition as of January 24, 1995. An audit also includes assessing
the accounting principles used and significant estimates made by the
Co-Trustees, as well as evaluating the overall Statement of Financial
Condition presentation. We believe that our audit provides a reasonable basis
for our opinion.

   In our opinion, the Statement of Financial Condition referred to above
presents fairly, in all material respects, the financial position of The
PaineWebber Pathfinders Trust, Treasury and Growth Stock Series 16 at January
24, 1995, in conformity with generally accepted accounting principles.

the Date of Deposit for this Series is 1,000,000.

                  (2) The initial fractional undivided interest represented by
each Unit of this series shall initially be 1/1,000,000th of the Trust Fund. A
Certificate representing the total number of Units outstanding on the initial

Section 2.03.

                  C.  The term "Record Date" shall mean June 30, September 30,
December 31 and March 31 of each year commencing June 30, 1995 except that with
respect to a distribution required by Section 2.02 (b), the Record Date shall be
the last business day of the month during which the contract to purchase the
Security fails and except that with respect to cash representing long-term
capital gains held in the Capital Account the Record Date shall be each December

                  Record Date shall also include such date or dates determined
by the Sponsor and the Trustee as necessary or desirable and in the best
interest of the Unitholders for federal or state purposes or for other purposes
(hereinafter a "Special Record Date") which date may replace a regularly
scheduled Record Date if such regularly scheduled Record Date is within 30 days
of a Special Record Date.

                  D.  The term "Distribution Date" shall mean the 20th
day following the Record Date, commencing July 20, 1995.

                  In the event a Special Record Date is declared, the
Distribution Date shall also include such Date as is determined by the Sponsor
and the Trustee to be the Distribution Date in respect of such Special Record.

                  E. The Discretionary Liquidation Amount shall be twenty per
centum (20%) of the aggregate value of (i) the Securities originally deposited
pursuant to Section 2.02 and (ii) any additional Securities deposited pursuant
to Section 2.02(c).

                  F.  The Mandatory Termination Date shall be March 2,
2004.  The date on which the Trustee shall begin to sell equity
Securities in accordance with Section 9.01 shall be February 1, 2004.

                  G.  The Trustee's annual compensation as referred to

<PAGE>





the preceding month.

                  H. The Sponsor's annual compensation pursuant to Section 7.02
shall be computed as $.00035 per Unit, based on the largest number of Units
Outstanding at any time during the calendar year.

                  I.  The balance in the Capital Account below which no
distribution need be made, as referred to in Section 3.04, is
$.0001 per Unit outstanding.

                  J.  Section 3.06 with regard to Portfolio Supervision
shall be amended to read as follows:

         1.       Subparagraph (e) shall be deleted and the following
                  text shall be inserted in its place as the current
                  version of paragraph (e);
                  "that a decline in price has occurred or such
                  materially adverse market or credit factors have
                  occurred, that in the opinion of the sponsor the
                  retention of such Securities would be detrimental to
                  the interest of the Unitholders"

         2.       In addition, there shall be added to Section 3.06 the
                  following subsections:
                  "(h) that there has been a decrease in the Sponsor's
                  internal rating of the Security; or
                   (i) that there has been a happening of events which, in the
                  opinion of the Sponsor, negatively affects the economic
                  fundamentals of the issuer of the Security or the industry of
                  which it is a part."

                  K. In the event that the Sponsor directs the Trustee to
distribute Securities in lieu of a cash redemption pursuant to Section 5.02, the
Trustee shall distribute only stock and stocks in a proportionate amount,
rounding to avoid the delivery of fractional shares and where such rounding is
not possible by delivering Stocks and an amount equal to the difference between
the Redemption Value and the value of such Stocks delivered (determined in
accordance with Section 4.01 on the date of tender).

                  L. The Percentage Ratios for the Trust shall be the percentage
ratios between the number of shares of each issue of stock in the Trust and the
maturity value of the Treasury obligations deposited in the Trust on the date
hereof. Such Percentage Ratios are subject to adjustment to reflect the
occurrence of (i) a stock split or a similar event which affects the capital
structure of the issuer of a stock but which does not affect the Trust's
percentage ownership of the common stock equity of such issuer at the time of
such event, (ii) a merger or reorganization or (iii) sale of any Securities from
the Trust portfolio. Stock dividends received by the Trust, if any, will

be sold by the Trustee and the proceeds therefrom shall be
treated as income to the Trust.

                  Re:      PaineWebber Pathfinders Trust,
                           Treasury and Growth Stock, Series 16

     (c)  Resolutions  of the  Executive  Committee  of the  Sponsor  adopted on
September  24,  1984,  certified  by the  Secretary  of the  Sponsor on the date
hereof;

     (d) Powers of Attorney as set forth in the  certificate of the Secretary of
the Sponsor dated the date hereof;

     (e) The  Registration  Statement on Form S-6 (File No. 33-49439) filed with
the Securities and Exchange Commission (the "Commission") in accordance with the
Securities  Act of 1933,  as  amended,  and the  rules  and  regulations  of the
Commission promulgated thereunder (collectively,  the "1933 Act") and amendments
thereto  including  Amendment No. 2 ("Amendment  No. 2") proposed to be filed on
January 24, 1995 (the "Registration Statement");

     (f) The Notification of Registration of the Trust filed with the Commission
under the Investment  Company Act of 1940, as amended  (collectively,  the "1940
Act") on Form N-8A, as amended, (the "1940 Act Notification");

<PAGE>





     (n) Such other pertinent records and documents as we have deemed necessary.

                  With your permission, in such examination, we have assumed the
following: (a) the authenticity of original documents and the genuineness of all
signatures; (b) the conformity to the originals of all documents submitted to us
as copies; (c) the truth, accuracy, and completeness of the information,
representations, and warranties contained in the records, documents, instruments
and certificates we have reviewed; (d) except as specifically covered in the
opinions set forth below, the due authorization, execution, and delivery on
behalf of the respective parties thereto of documents referred to herein and the
legal, valid, and binding effect thereof on such parties; and (e) the absence of
any evidence extrinsic to the provisions of the written agreement(s) between the
parties that the parties intended a meaning contrary to that expressed by those
provisions. However, we have not examined the securities deposited pursuant to
the Indenture and Agreement (the "Securities") nor the contracts for the
Securities.

                  We express no opinion as to matters of law in jurisdictions
other than the States of New York and California and the United States, except
to the extent necessary to render the opinion as to the Sponsor and the
Indenture and Agreement in paragraphs (i) and (iii) below with respect to
Delaware law. As you know we are not licensed to practice law in the State of
Delaware, and our opinion in paragraph (i) and (iii) as to Delaware law is based
solely on review of the official statutes of the State of Delaware.

                  Based upon such examination, and having regard for legal
considerations which we deem relevant, we are of the opinion that:

                  (i) The Sponsor is a corporation duly organized, validly
existing, and in good standing under the laws of the State of Delaware with full
corporate power to conduct its business as described in the Prospectus;

                  (ii) The Sponsor is duly qualified as a foreign corporation
and is in good standing as such within the State of New York;

                  (iii) The Indenture and Agreement has been duly authorized,
executed and delivered by the Sponsor and, assuming the due authorization,
execution and delivery by the Trustee, is a valid and binding agreement of the
Sponsor, enforceable against the Sponsor in accordance with its terms;

                  (iv) The Trust has been duly formed and is validly existing as
an investment trust under the laws of the State of New York and has been duly
registered under the Investment







      
<PAGE>





Company Act of 1940;

                  (v)  The terms and provisions of the Units conform in
all material respects to the description thereof contained in
the Prospectus;

                  (vi) The consummation of the transactions contemplated under
the Indenture and Agreement and the fulfillment of the terms thereof will not be
in violation of the Sponsor's Restated Certificate of Incorporation, as amended,
or By-Laws, as amended and will not conflict with any applicable laws or
regulations applicable to the Sponsor in effect on the date hereof;

                  (vii) The Certificates to be issued by the Trust, when duly
executed by the Sponsor and the Co-Trustees in accordance with the Indenture and
Agreement, upon delivery against payment therefor as described in the
Registration Statement and Prospectus will constitute fractional undivided
interests in the Trust enforceable against the Trust in accordance with their
terms, will be entitled to the benefits of the Indenture and Agreement and will
be fully paid and non-assessable; and

                  (viii) While the Registration Statement has not yet become
effective we have no reason to believe that such Registration Statement will not
become effective within 30 days after the date hereof.

                  In additon, we have participated in conferences with
representatives of the Sponsor, the Trustee, the Trust's accountants and others
concerning the Registration Statement and the Prospectus and have considered the
matters required to be stated therein and the statements contained therein,
although we have not independently verified the accuracy, completeness or
fairness of such statements. Based upon and subject to the foregoing, nothing
has come to our attention to cause us to believe that the Registration
Statement, as of the date hereof, contained an untrue statement of a material
fact or omitted to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, or that the Prospectus, as of the date
hereof, contained an untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading (it being understood that we have not been requested to and do
not make any comment in this paragraph with respect to the financial statements,
schedules and other financial and statistical information contained in the
Registration Statement or the Prospectus).

                  Our opinion that any document is valid, binding, or
enforceable in accordance with its terms is qualified as to:

                  (a) limitations imposed by bankruptcy, insolvency,
reorganization, arrangement, fraudulent conveyance, moratorium, or other laws
relating to or affecting the enforcement of creditors' rights generally;

                  (b) rights to indemnification and contribution which
may be limited by applicable law or equitable principles; and

                  (c) general principles of equity, regardless of whether such
enforceability is considered in a proceeding in equity or at law.

                  We hereby consent to the filing of this opinion as an exhibit
to the Registration Statement and to the use of our name wherever it appears in

Dear Sirs:

                  As counsel for PaineWebber Incorporated (the "Depositor"), we
have examined an executed copy of the Trust Indenture and Agreement dated as of
January 24, 1995 (the "Indenture") and Standard Terms and Conditions of Trust,
dated as of September 1, 1990 (the "Agreement"), both between the Depositor, and
Investors Bank & Trust Company and The First National Bank of Chicago as
Co-Trustees. The Indenture established a trust called PaineWebber Pathfinders
Trust, Treasury and Growth Stock Series 16 (the "Trust") into which the
Depositor deposited certain United States Treasury obligations, or evidences
thereof, and stocks (the "Securities"), and moneys to be held by the Co-Trustees
upon the terms and conditions set forth in the Indenture and Agreement. Under
the Indenture, certificates of ownership were issued on the initial Date of
Deposit representing 1,000,000 units of fractional undivided interest in the
Trust (the "Units").

                  Based upon the foregoing and upon an examination of such other
documents and an investigation of such matters of law as we have deemed
necessary, we are of the opinion that, under existing statutes and decisions:

         1. The Trust is not an association taxable as a corporation for Federal
income tax purposes. Under the Internal Revenue Code of 1986, as amended (the
"Code"), each holder of a certificate of ownership (a "Unitholder") will be
treated as the owner of a pro rata portion of the Trust, and income of the Trust
will be treated as income of the Unitholder.







      
<PAGE>






SIGNATURE

                  2. Each Unitholder will have a taxable event when the Trust
disposes of a Security (whether by sale, exchange, redemption, or payment at
maturity) or when the Unitholder redeems or sells its Unit. For purposes of
determining gain or loss, the total tax cost of each Unit to a Unitholder is
allocated among each of the Securities, in accordance with the proportion of the
Trust comprised by each Security, to determine the Unitholder's per Unit tax
cost for each Security.

                  3. The Trust is not an association taxable as a corporation
for New York State income tax purposes. Under New York State Law, each
Unitholder will be treated as the owner of a pro rata portion of the Trust, and
the income of the Trust will be treated as income of the Unitholders.

                  We hereby consent to the filing of this opinion as an exhibit
to the Registration Statement (File No. 33-49439) relating to the Units referred
to above and to the use of our name and to the reference to our firm in said
Registration Statement and in the related Prospectus.
