PAINEWEBBER PATHFINDERS TRUST, TREASURY AND 
GROWTH STOCK
SERIES FIFTEEN  -  PART A

Brief Description of the Trust's Investment 
Portfolio

1. The Trust's Objective.

The Trust seeks to provide preservation of 
capital and potential capital appreciation 
through an investment in a portfolio of stripped 
"zero-coupon" United States Treasury obligations 
maturing on February 15, 2005 and common stocks. 
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 March 2, 2005, the Trust's 
"Mandatory Termination Date".

As of the date of this Prospectus Part A, 38% of 
the Trust's Portfolio was invested in interest-
only portions of United States Treasury 
obligations and the remaining 62% was invested in 
common stocks as described briefly below.

The stripped "zero-coupon" U.S. Treasury 
Obligations make no payment of current interest, 
but rather make a single payment upon their 
stated maturity. PaineWebber chose the stocks in 
the Trust's Portfolio for their capital 
appreciation potential, not for their income 
potential. Many of the stocks currently pay 
little or no dividend income.

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 purchased their Units at or below 
$1,000 per 1,000 Units and who hold their units 
to the Mandatory Termination Date 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.

2. Brief Description of the Trust's Portfolio.

The Trust is a unit investment trust which means 
that, unlike a mutual fund, the Trust's Portfolio 
is not managed and the Trust Portfolio's 
investments are not sold because of market 
changes.

Unless terminated sooner, the Trust is scheduled 
to terminate on or about March 2, 2005 regardless 
of market conditions at the time. The Trust plans 
to hold until its termination the U.S. Treasury 
obligations maturing February 15, 2005 and a 
diversified group of stocks, all as shown on the 
"Schedule of Investments" in this Prospectus Part 
A.

The main objective of PaineWebber in constructing 
the portfolio of stocks to be included in the 
Trust 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.

On October 31, 1998, the aggregate market value 
of the Trust Portfolio was $35,615,689.

When the Trust's Portfolio was constructed in 
1993, a computer program was generated against 
the 500 S&P stocks to identify a combination of 
35 S&P 500 stocks (excluding those stocks rated 
"Unattractive" or "Sell" by PaineWebber Equity 
Research) which, when equally weighted, have the 
highest correlation with the S&P 500 Index with 
the smallest tracking error. 

When the Trust was first created, a number of 
stocks related to the "electronic superhighway" 
were included in the Trust Portfolio.  
PaineWebber used the term "electronic 
superhighway" to describe the integration of 
television, telephone, radio, computer and other 
methods of sending, sharing and storing 
electronic information.  The rest of the Trust 
Portfolio, in the Sponsor's opinion, held a 
diversified group of companies in the 
transportation, construction, financial and 
consumer related fields to provide balance to the 
Trust Portfolio.

As of October 31, 1998, the Trust Portfolio holds 
42* stocks, 13 of which are in the electronic 
superhighway.

The common stocks in the Trust's Portfolio have 
been issued by companies who receive income and 
derive revenues from multiple industry sources, 
but whose primary industry is listed in the  
"Schedule of Investments" in this Prospectus Part 
A.  A brief description of these  issuers can be 
found in Part B of this Prospectus.

Is this Trust Appropriate for You?

Yes, if you are a long-term investor 
seeking capital protection combined with 
potential capital appreciation over the life of 
the Trust. You will benefit from a professionally 
selected portfolio whose risk is reduced by 
investing in stocks of several different issuers.

No, if you want a speculative investment 
that changes to take advantage of market 
movements, if you are unable or unwilling to 
assume the risks involved generally with equity 
investment or if you need current income.

Summary of Risks

You can lose money by investing in the 
Trust.  This can happen for various reasons.  A 
further discussion of the risks summarized below 
can be found in Part B of this Prospectus.

1. Risks of Investing in the Trust

Certain risks are involved with an 
investment in a unit trust which holds stripped 
"zero-coupon" U.S. Treasury obligations and 
common stocks.  For example:

The Trust, unlike a mutual fund, is not 
"managed", so neither the U.S. Treasury 
Obligations nor the stocks will be sold by the 
Trust to take advantage of market fluctuations.

The Trust Portfolio may not remain constant 
during the life of the Trust.  The Trustee may be 
required to sell stocks to pay Trust expenses, to 
tender stocks under certain circumstances or to 
sell stocks in the event certain negative events 
occur.

The sale of stocks from 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 you receive upon termination may be less 
than the amount you paid.

If many investors sell their Units, the Trust 
will have to sell Portfolio Securities.  This 
could reduce the diversification of your 
investment and increase your share of Trust 
expenses.

The price of your Units depends upon the full 
range of economic and market influences including 
the prices of bonds and equity securities, 
current interest rates, the condition of the bond 
and stock markets and other economic influences 
that affect the global or Untied States economy.

Assuming no changes occur in the prices of the 
U.S. Treasury Obligations and the stocks held by 
the Trust, the price you paid for your Units will 
generally be less then the price you paid because 
your purchase price included a sales charge.

The stocks in the Trust's Portfolio will 
generally trade on a domestic stock exchange or 
in the over-the-counter market.  We cannot assure 
you that a liquid trading market will exist.  The 
value of the Trust's Portfolio, and of your 
investment, may be reduced if trading in one or 
more stocks is limited or absent.

Additional stocks and U.S. Treasury Obligations 
may be acquired by the Trust when additional 
Units are to be offered to the public.  Costs 
incurred in acquiring such additional stocks and 
Treasury Obligations will be borne by the Trust.  
Unitholders will experience a dilution of their 
investment as a result of such brokerage fees and 
other expenses paid by the Trust during the 
additional deposits of securities purchased by 
the Trustee with cash or cash equivalents.

Investing always involves risk.  The risks 
described below are the most significant risks 
associated with investing in the U.S. Treasury 
Obligations and stocks held by the Trust.

2. Risks of Investing in Stripped "Zero-Coupon" 
U.S. Treasury Obligations

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.  
Owners of deep discount bonds which make no 
current interest payments earn a fixed yield not 
only on the original investment but also on all 
earned discount during the life such obligation.  
This implicit reinvestment of earnings at the 
same, fixed rate eliminates the owner's ability 
to reinvest at higher rates in the future.  For 
this reason, 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.

3. Risks of Investing in Stocks

Holders of common stocks such as those held by 
the Trust have rights that are generally inferior 
to the holders of debt obligations or preferred 
stocks.

Common stocks are not obligations of the issuer. 
Therefore, they do not provide any assurance of 
income or provide the degree of protection of 
debt securities.

The stocks held by the Trust can be expected to 
fluctuate in value depending on a wide variety of 
factors, such as economic and market influences 
affecting corporate profitability, financial 
condition of issuers, changes in worldwide or 
national economic conditions, the prices of 
equity securities in general and the Trust's 
stocks in particular.

Certain of the stocks in the Trust may be 
American Depositary Receipts or "ADRs" which are 
subject to additional risks.  (See "Schedule of 
Investments" herein.)  ADRs are subject to 
certain investment risks that are different from 
those experienced by Stocks issued by domestic 
issuers.  These investment risks include 
potential future political and economic 
developments and the potential establishment of 
exchange controls, new or higher levels of 
taxation, or other governmental actions which 
might adversely affect the payment or receipt of 
payment of dividends on the common stock of 
foreign issuers underlying such ADRs. ADRs may 
also be subject to current foreign taxes, which 
could reduce the yield on such securities.

The securities underlying the ADRs held in the 
Trust are generally denominated, and pay 
dividends, in foreign currency and are therefore 
subject to currency exchange rate risk.  Currency 
exchange rate risk occurs because the U.S. dollar 
value of the shares underlying the ADRs and of 
their dividends will vary with the fluctuations 
in the U.S. dollar foreign exchange rates for the 
relevant currency in which the shares underlying 
the ADRs are denominated.  Exchange rate 
fluctuations are dependent on a number of 
economic factors including the world economy and 
the economic conditions within the relevant 
country, supply and demand of the relevant 
currency, interest rate differentials between 
currencies, the balance of imports and exports of 
goods and services, monetary and fiscal policies 
of the relevant country, perceived political 
stability and investor psychology, especially 
that of institutional investors predicting the 
future relative strength or weakness of a 
particular currency.

Year 2000 Problem Risk

 Many computer systems were designed in such a 
way that they may be unable to distinguish 
between the year 2000 and the year 1900 and 
therefore may not properly process and calculate 
date-related information and data (commonly know 
as the "Year 2000 Problem").  As with all 
investment and financial companies, the Year 2000 
Problem may have an adverse impact upon the 
Trust.  The Sponsor and the Trustee are taking 
steps to address the year 2000 Problem with 
respect to the computer systems they use and to 
obtain reasonable assurances that similar steps 
are being taken by the Trust's other service 
providers.  At this time, however, there can be 
no assurance that these steps will be sufficient 
to avoid any adverse impact to the Trust. The 
year 2000 Problem is expected to have an impact 
on all corporations, including those whose stocks 
are contained in the Trust's Portfolio. The 
Sponsor cannot predict what impact, if any, the 
year 2000 Problem will have on the stocks in the 
Trust.

THE UNITHOLDERS, SPONSOR AND CO-TRUSTEES
THE PAINEWEBBER PATHFINDERS TRUST, TREASURY AND 
GROWTH STOCK SERIES FIFTEEN: 
 We have audited the accompanying statement of 
financial condition, including the schedule of 
investments, of The PaineWebber Pathfinders 
Trust, Treasury and Growth Stock Series Fifteen 
as of October 31, 1998 and the related statements 
of operations and changes in net assets for each 
of the three years in the period then ended. 
These financial statements are the responsibility 
of the Co-Trustees. Our responsibility is to 
express an opinion on these financial statements 
based on our audits. 
 We conducted our audits in accordance with 
generally accepted auditing standards. Those 
standards require that we plan and perform the 
audit to obtain reasonable assurance about 
whether the financial statements are free of 
material misstatement. An audit includes 
examining, on a test basis, evidence supporting 
the amounts and disclosures in the financial 
statements. Our procedures included confirmation 
of the securities owned as of October 31, 1998, 
as shown in the statement of financial condition 
and schedule of investments, by correspondence 
with the Co-Trustees. An audit also includes 
assessing the accounting principles used and 
significant estimates made by the Co-Trustees, as 
well as evaluating the overall financial 
statement presentation. We believe that our 
audits provide a reasonable basis for our 
opinion. 
 In our opinion, the financial statements 
referred to above present fairly, in all material 
respects, the financial position of The 
PaineWebber Pathfinders Trust, Treasury and 
Growth Stock Series Fifteen at October 31, 1998 
and the results of its operations and changes in 
its net assets for each of the three years in the 
period then ended, in conformity with generally 
accepted accounting principles.

           THE PAINEWEBBER PATHFINDERS TRUST
       TREASURY AND GROWTH STOCK SERIES FIFTEEN
            NOTES TO FINANCIAL STATEMENTS
               October 31, 1998
 (A) The financial statements of the Trust are 
prepared on the accrual basis of accounting. 
Security transactions are accounted for on the 
date the securities are purchased or sold. The 
original issue discount on the Treasury 
Obligation is accreted on a level yield basis. 
The amount of discount included in the cost of 
the Treasury Obligation held as of October 31, 
1998 is $3,119,855.
 (B) Cost to investors represents the initial 
public offering price as of the initial date of 
deposit, and the value of units through 
supplemental deposits computed on the basis set 
forth under "Public Offering Price of Units", 
adjusted for accretion on United States Treasury 
Obligations and for securities sold since the 
date of deposit. 
 (C) Sales charge of the Public Offering Price 
per Unit is computed on the basis set forth under 
"Public Offering of Units - Sales Charge and 
Volume Discount". 
 (D) At October 31, 1998, the gross unrealized 
market appreciation was $15,637,447 and the gross 
unrealized market depreciation was ($159,007).The 
net unrealized market appreciation was 
$15,478,440. 
 (E) Regular distributions of net income, 
excluding accretion income and principal receipts 
not used for redemption of units are made semi-
annually. Special distribution may be made when 
the Sponsor and Co-Trustee deem necessary. Income 
with respect to the accretion of original issue 
discount is not distributed although the 
unitholder is subject to tax, where applicable, 
as if the distribution had occurred. Accretion 
income earned by the Trust increases a 
unitholder's cost basis in the underlying 
security.
 (F) The following units were redeemed with 
proceeds of securities sold as follows:

               PROSPECTUS PART B 
     PART B OF THIS PROSPECTUS MAY NOT BE 
     DISTRIBUTED UNLESS ACCOMPANIED BY PART A.
Part B contains a description of the important 
features of the PaineWebber Pathfinders Trust 
Treasury and Growth Stock Series 15 and also 
includes a more detailed discussion of the 
investment risks that a Unitholder might face 
while holding Trust Units.

           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 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. Unitholders can 
sell units at any time at the then current net 
asset value with no additional sales charge. (See 
Public Offering of Units--Secondary Market for 
Units and Redemption.) 

 When the Trust Portfolio was selected on 
November 30, 1993, PaineWebber designed the 
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 
Growth Stocks.

 The selection criteria employed first identified 
all stocks which were then in the "buy" or 
"attractive" categories as ranked by those 
PaineWebber equity analysts following such 
stocks. This selection resulted in 243 candidate 
stocks. A computer optimization program was then 
run against the 243 candidate stocks to construct 
the portfolio. The optimization program was 
designed to maximize returns as stated by the 
user's forecast of specific stocks or model 
portfolios while minimizing the portfolio's 
performance divergence as measured against a 
specific benchmark, in this case the S&P 500 
Index (the "S&P 500"). The optimizer program used 
in constructing the Trust's portfolio was modeled 
to favor, or "tilt" toward, growth stocks. The 
program produced a portfolio of 35 stocks with a 
tracking error of 3.90% versus the S&P 500 
(i.e.), there was a 2/3 probability that the 
return generated by the program-picked portfolio 
would differ over the course of one year from the 
S&P 500's return by no more than 3.9%.  Finally, 
an examination of each of the 35 stocks was made 
to ensure that the issue's business mix and the 
relative weightings of each stock were consistent 
with the initial objectives of the Trust.

 The Trust portfolio, in PaineWebber's opinion, 
is comprised of a diversified group of large, 
well-known 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 in Part A 
above. For a list of the individual common stocks 
comprising each industry group listed below, 
investors should consult the "Schedule of 
Investments" in Part A above.

 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".

                ABOUT THE TRUST

 The Trust is one of a series of similar but 
separate unit investment trusts created by the 
Sponsor pursuant to a Trust Indenture and 
Agreement* (the "Indenture") dated as of the 
Initial Date of Deposit, 

_________________
*  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.
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 Initial 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. (See "Risk 
Factors and Special Considerations" however, for 
a discussion of AT&T stock held by 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. 

 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 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 Initial 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. 

 Certain of the Stock in the Trust may be ADRs 
which are subject to additional risks. (See 
"Schedule of Investments" herein.) ADRs evidence 
American Depositary Shares ("ADS"), which, in 
turn, represent common stock of foreign issuers 
deposited with a custodian in a depositary. (For 
purposes of this Prospectus, the term "ADR" 
generally includes "ADS".) ADRs involve certain 
investment risks that are different from those 
experienced by Stocks issued by domestic issuers. 
These investment risks include potential future 
political and economic developments and the 
potential establishment of exchange controls, new 
or higher levels of taxation, or other 
governmental actions which might adversely affect 
the payment or receipt of payment of dividends on 
the common stock of foreign issuers underlying 
such ADRs. ADRs may also be subject to current 
foreign taxes, which could reduce the yield on 
such securities. Also, certain foreign issuers 
are not subject to reporting requirements under 
certain U.S. securities laws and therefore may 
make less information publicly available than 
that afforded by their domestic counterparts. 
Further, foreign issuers are not necessarily 
subject to uniform financial reporting, auditing 
and accounting standards, requirements and 
practices such as are applicable to domestic 
issuers. 

 In addition, the securities underlying the ADRs 
held in the Trust are generally denominated, and 
pay dividends, in foreign currency. An investment 
in securities denominated and principally traded 
in foreign currencies involves investment risk 
substantially different than an investment in 
securities that are denominated and principal 
traded in U.S. dollars. This is due to currency 
exchange rate risk, because the U.S. dollar value 
of the shares underlying the ADRs and of their 
dividends will vary with the fluctuations in the 
U.S. dollar foreign exchange rates for the 
relevant currency in which the shares underlying 
the ADRs are denominated. The Trust, however, 
will compute its income in United States dollars, 
and to the extent any of the Stocks in the Trust 
pay income or dividends in foreign currency, the 
Trust's computation of income will be made on the 
date of its receipt by the Trust at the foreign 
exchange rate in effect on such date. PaineWebber 
observes that, in the recent past, most foreign 
currencies have fluctuated widely in value 
against the U.S. dollar for many reasons, 
including the soundness of the world economy, 
supply and demand of the relevant currency, and 
the strength of the relevant regional economy as 
compared to the economies of the United States 
and other countries. Exchange rate fluctuations 
are also dependent, in part, on a number of 
economic factors including economic conditions 
within the relevant country, interest rate 
differentials between currencies, the balance of 
imports and exports of goods and services, and 
transfer of income and capital from one country 
to another. These economic factors in turn are 
influenced by a particular country's monetary and 
fiscal policies, perceived political stability 
(particularly with respect to transfer of 
capital) and investor psychology, especially that 
of institutional investors predicting the future 
relative strength or weakness of a particular 
currency. As a general rule, the currency of a 
country with a low rate of inflation and a 
favorable balance of trade should increase in 
value relative to the currency of a country with 
a high rate of inflation and deficits in the 
balance of trade. 

 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 (or the relevant foreign 
currency exchange rate, if applicable) 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 (and currency) 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 (and currency) 
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 Carter, Ledyard & Milburn, 
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. The tax treatment of non-U.S. 
investors is not addressed.  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 basis 
for such Stock.  This reduction in basis would in 
effect increase any gain, or reduce any loss, 
realized by the Unitholder on any subsequent sale 
or other disposition of Units.  After the tax 
cost 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.

 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 may exceed amounts distributed to the 
extent amounts 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 and be taxed at a 20 percent effective tax 
rate.  Individuals, partnerships, trusts, S 
corporations and certain other entities are not 
eligible for the dividends-received deduction.

 Unitholders will be taxed in the manner 
described above regardless of whether 
distributions from the Trust are actually 
received by the Unitholder or are reinvested 
pursuant to the reinvestment plan.

 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 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 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 which 
(with respect to such Unitholder) has original 
issue discount.  The amount of accrued original 
issue discount included in income with respect to 
a Unitholder's  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.

 Capital gains realized by non corporate 
taxpayers are generally taxable at a maximum rate 
of 20% if the taxpayer has a holding period of 
more than 12 months.

 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 may 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).

 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 
of Units 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".)

 Sales Charge and Volume Discount.  Sales charges 
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 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 does not intend to impose 
a sales charge on such employee sales.

 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 Series (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 Municipal 
Bond Trust, Insured Series (the "Insured 
Series"); The Corporate Bond Trust, (the 
"Corporate Series"); The PaineWebber Pathfinders 
Trust, (the "Pathfinders Series"), The 
PaineWebber Federal Government Trust, (the 
"Government 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. Unitholders of this 
Trust are not eligible for the Exchange Option 
into (1) any Exchange Trust designated as a 
rollover series for the 30 day period prior to 
termination of such Trust or (2) any Exchange 
Trust subject to a deferred sales charge. 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 expense 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 sales charge that was less than 
the per Unit sales charge of the series of 
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 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, but 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," i.e., a Unitholder 
will recognize a tax gain or loss which will be 
of a capital or ordinary income nature depending 
upon the length of time he has held his Units and 
other factors. 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 indicated 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 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. In addition to the Exchange 
Option described in this Prospectus, 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 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 is 
$250. 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 one-half of the highest 
applicable sales charge and the dealer concession 
will be retained by the Sponsor. In 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 and does not 
intend to sell Units to persons who are non-
resident aliens.

 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 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.

 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 sells or redeems the 
Units, which is based on the value of the 
Securities, determined by the Trustee as 
described under "Valuation". 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.

 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 Initial 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

 One or more Units represented by a Certificate 
may be tendered to Investors Bank & Trust Company 
for redemption at its office at Hancock Towers, 
200 Clarendon Street, Boston, MA 02116 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 Investors Bank 
& Trust Company. Units redeemed by Investors Bank 
& Trust will be canceled. The Certificate must be 
properly endorsed and accompanied by a letter 
requesting transfer. Unitholders must sign 
exactly as their names appear on the face of the 
Certificate with the signature guaranteed by a 
national bank or trust company, or by a member 
firm of the New York, Midwest, or Pacific Coast 
Stock Exchange, or in such other manner as may be 
acceptable to Investors Bank & Trust Company. In 
certain instances the Investors Bank & Trust 
Company 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 Investors 
Bank & Trust Company to determine whether 
additional documents are necessary.

 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, determined on 
the basis of the current bid prices for the 
Treasury Obligation plus the market value for the 
Stocks 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, it is 
deemed received on the next business day. The 
Sponsor may purchase Units tendered to the 
Trustee for redemption. During the period in 
which the Sponsor maintains a secondary market 
for Units, the Sponsor may repurchase any Unit 
presented for tender to the Trustee for 
redemption no later than the close of business on 
the second 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 and 
as directed by the sponsor which direction shall 
be given 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 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 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 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 and (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 
deducting therefrom the sum of (x) taxes or other 
governmental charges against the Trust not 
previously deducted and (y) accrued fees and 
expenses of the Trustee and the Sponsor 
(including legal and auditing expenses) and other 
Trust expenses. 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 Saturdays, Sundays, New Year's 
Day, Martin Luther King, Jr.'s Day, Presidents' 
Day, Good Friday, Memorial Day, Independence Day, 
Labor Day, Thanksgiving Day and Christmas Day and 
other days that the New York Stock Exchange is 
closed.

 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 
therefore 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.

 Treasury Obligations are valued on the basis of 
bid prices. The aggregate 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 prices are not 
available, on the basis of current bid 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 Initial 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 not to exceed $.00025 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.

 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 $.00102 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 in connection with the 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 Investors Bank & 
Trust Company 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 Investors Bank & Trust Company 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 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 (except stock 
dividends) and interest, if any, accrued by the 
Trust. All other receipts (i.e. return of 
principal, stock dividends, if any, and gains) 
are credited on its books to a Capital Account. 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.

 Investors Bank & Trust Company keeps records and 
accounts of the Trust at its office, 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 1994, 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.

 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 the 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 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.

             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 Initial 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.

 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

 The Indenture provides that the Trustee will not

reliance on properly executed documents or the 
disposition of moneys, Securities or Certificates 
or in respect of any valuation which it is

gross negligence, bad faith or wilful misconduct, 
nor will the Trustee be liable or responsible in 
any way for depreciation or loss incurred by 
reason of the sale by the Trustee of any

act and will not be liable for any such action

  Ladies and Gentlemen:
  We have served as counsel for PaineWebber Incorporated as
  sponsor and depositor (the "Depositor") of PaineWebber
  Pathfinders Trust, Treasury and Growth Stock Series 15 
  (hereinafter referred to as the "Trust"). It is proposed that 
  Post-Effective Amendment No. 5 to the Trust's registration statement
  ("Post-Effective Amendment No. 5") will be filed with the Securities
  and Exchange and dated as of the date hereof in connection with the
  continued issuance by the Trust of an indefinite number of units of
  fractional undivided interest in the Trust (hereinafter referred
  to as the "Units") pursuant to Rule 24f-2 promulgated under the
  provisions of the Investment Company Act of 1940, as amended.
  In this regard, we have examined executed originals or copies of the
  following:
  (a)  The Restated Certificate of Incorporation, as amended, and the
       By-Laws of the Depositor, as amended;
  (b)  Resolutions of the Board of Directors of the Depositor adopted on
       December 3, 1971 relating to the Trust and the sale of the Units;
  (c)  Resolutions of the Executive Committee of the Depositor adopted
       on September 24, 1984;
  (d)  Powers of Attorney referred to in the Amendment;
  (e)  Post-Effective Amendment No. 5 to the Registration Statement on
       Form S-6 (File No. 33-49437) to be 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") proposed to be filed on or about the
       date hereof (the "Amendment");
  (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;
  (g)  The registration of the Trust filed with the Commission under the
       1940 Act on Form N-8B-2 (File No. 811-4158), as amended;
  (h)  The prospectus included in the Amendment (the "Prospectus");
  (i)  The Standard Terms and Conditions of the Trust dated as of
       September 1, 1990, as amended, among the Depositor, and
       Investors Bank & Trust Company and the First National Bank of Chicago
       (the "Trustee"), as successor Co-Trustee, (the "Standard
       Terms");
  (j)  The Trust Indenture dated as of the Initial Date of Deposit, among
       the Depositor, the Co-Trustees and the Evaluator (the "Trust
       Indenture" and, collectively with the Standard Terms, the
       "Indenture and Agreement");
  (k)  The form of certificate of ownership for units (the "Certificate") to
       be issued under the Indenture and Agreement; and
  (l)  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 State of New York (except "Blue Sky" laws) and the federal laws
  of the United States, except to the extent necessary to render the 
  opinion as to the Depositor in paragraph (i) 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 Depositor 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 Depositor is duly qualified as a foreign corporation and is in
       good standing as such within the State of New York;
  (iii)The terms and provisions of the Units conform in all material
       respects to the description thereof contained in the Prospectus;
  (iv) 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 Depositor'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
       Depositor in effect on the date hereof; and
  (v)  The Certificates to be issued by the Trust, when duly executed by
       the Depositor and the Trustee in accordance with the Indenture
       and Agreement, upon delivery against payment therefor as
       described in the 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.
  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 represent that the Amendment contains no disclosure
  which would render it ineligible to become effective immediately
  upon filing pursuant to paragraph (b) of Rule 485 of the
  Commission.
       We hereby consent to the filing of this opinion as an exhibit to
  the Amendment and to the use of our name wherever it appears in
  the Amendment and the Prospectus.
  Very truly yours,
  /s/ CARTER, LEDYARD & MILBURN
