PAINEWEBBER EQUITY TRUST, GROWTH STOCK SERIES 25 - PROSPECTUS PART A

BRIEF DESCRIPTION OF THE TRUST

1. THE TRUST'S OBJECTIVES.


   o   The Trust invests in a fixed portfolio of domestic [and foreign stocks]
       which have, in PaineWebber's opinion, an above-average potential for
       capital appreciation because the issuers of such stocks may be attractive
       candidates for acquisition.

   o   The Trust plans to hold until its termination on [date] a diversified
       portfolio of stocks which PaineWebber selected on      , 2000, the first
       day of the Trust.


   o   As of the first day of the Trust, PaineWebber believes that the Trust's
       portfolio of stocks have the potential for achieving above-average
       capital appreciation during the life of the Trust.

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



2. THE PORTFOLIO'S INVESTMENT STRATEGY IS TO INVEST IN STOCKS OF ATTRACTIVE
   ACQUISITION TARGETS.

   o   PaineWebber observes that today most companies find themselves in a
       hyper-competitive environment where raising prices is very difficult or
       impossible; competition is increasingly global rather than national; the
       Internet is expanding industry capacity and lowering price points as
       online players enter the market; and traditional cost-cutting is
       difficult because of tight labor markets and rising costs for such things
       as advertising, rent and energy. Somewhat paradoxically, however, while
       competition is intense, business is strong in a setting of benign
       deflation. The U.S. is booming and economic growth is robust in most
       foreign economies. Corporate cash flows are strong and business
       confidence remains high.

   o   PaineWebber believes that in this environment of hyper-competitive
       prosperity, many companies will continue to expand through acquisition,
       because they need to do deals in order to grow and remain competitive,
       and they have the ability to finance acquisitions with cash, debt or the
       issuance of new shares. Merger and acquisition activity may or may not
       actually accelerate over the next year, but it should at least remain
       around its current pace, which is nearly the highest in the past two
       decades. The most common reason to do deals, according to a survey of
       PaineWebber Equity Research Analysts, is to expand sales and increase a
       firm's market dominance -- i.e., to become more like a "Gorilla," which
       PaineWebber defines as a company that already has the leading market
       share in an industry and is still gaining share.

   o   Although every deal is different, PaineWebber observes the logic behind
       many acquisitions is as follows: Company A (the acquiring company), a
       large, well-managed company with a strong franchise but decelerating
       sales growth, buys a smaller firm, Company T (the target company), and
       then:

       o   Achieves cost synergies by closing Company T's headquarters and
           eliminating other duplicative facilities and functions.
       o   Takes Company T's best products and pushes them through Company A's
           well-honed distribution system.
       o   Sells off Company T's weak businesses and other assets, thereby
           raising cash that can be used to help pay for the acquisitions.



                                      A-3
<PAGE>


   o   In PaineWebber's opinion, for Company A the deal delivers important
       benefits, which may include:

       o   Faster sales growth
       o   New opportunities for cost-cutting
       o   New technology
       o   Increased economies of scale
       o   Improved economies of scope -- such as being able to offer a more
           complex menu of goods and services
       o   Greater market power: because it is now bigger, Company A is in a
           better position to negotiate with suppliers, distributors and
           customers
       o   Expansion into new geographic regions

   o   PaineWebber believes that such deals are both offensive and defensive:
       they accelerate growth while making a company less vulnerable to the
       growth of others. Of course, they are not without risk: a botched
       acquisition can damage earnings growth and significantly lower a stock's
       market price or value.

   o   The Trust plans to hold until its termination on March , 2003 a portfolio
       of stocks of companies which PaineWebber believes are attractive
       acquisition targets, and will benefit from strong merger and acquisition
       activity. PaineWebber believes that the 51 companies mentioned below
       could be acquired for the aforementioned reasons:

       -   Basic Industry -- this industry sector is generally out of favor
           among investors, and the resulting depressed stock prices could spark
           leveraged buy out or merger and acquisition activity.
           o   Chemicals (Delta and Pine Land, Sherwin Williams)
           o   Papers (Potlatch, Temple Inland)
       -   Communications -- companies in these industry sectors are likely to
           be attractive acquisitions because they may offer acquiring companies
           access to new geographical areas, customers and vendors.
           o   Broadcasting (Citadel Communications, Clear Channel
               Communications)
           o   Cable and Satellite (Pegasus Communications)
           o   Telecommunications Services (Qwest Communications)
           o   Wireless Services (VoiceStream Wireless)
       -   Consumer Products -- acquiring companies in these industry sectors
           will most likely try to achieve improvements in growth initiatives,
           product platforms, competitive positions and distribution systems
           through acquisitions or mergers.
           o   Beverages (Cott Corporation, Triarc Companies)
           o   Foods (Heinz, Quaker Oats, Ralston Purina)
           o   Household Products (Clorox, Gillette)
       -   Consumer Retailing -- the sectors in this industry have been
           significantly affected by the rise of the Internet and electronic
           commerce, and they should continue to consolidate due to lowered
           valuations of department stores and the desire by retailers to reap
           economies of scale in everything from data systems to supply chain
           efficiencies.
           o   Blockbuster (Specialty)
           o   J.C. Penney (Broadlines)
           o   Ross Stores (Softlines)


                                      A-4
<PAGE>


       -   Energy -- the energy sector is rapidly consolidating, as companies
           seek cost-cutting opportunities that will drive earnings growth even
           if oil prices are low, as they were in 1998.
           o   Exploration and Production (Ocean Energy, Triton Energy)
           o   International and Domestic Oils (Occidental Petroleum, Unocal)
           o   Natural Gas (Equitable Resources, Southwest Gas)
       -   Financial Services -- acquiring companies in these industry sectors
           should continue to seek access to new business lines and the benefits
           of strong brand recognition.
           o   Banks (Bank One, Chase Manhattan)
           o   Consumer Finance (Countrywide Credit, Household International)
           o   Insurance (Allstate, Chubb, Lincoln National)
       -   Health Care -- acquisitions in these industry sectors should offer
           acquiring companies the benefits of economies of scale, established
           distribution systems and cost savings from synergies which provide an
           incremental source of earnings growth.
           o   Health Care Services/Facilities (Sunrise Assisted Living)
           o   Health Maintenance Organizations (Healtheon/WebMD, Oxford Health
               Plans)
           o   Medical Devices (Becton Dickinson, C.R. Bard)
           o   Pharmaceuticals (Eli Lilly, Schering Plough)
       -   Technology -- mergers and acquisitions in these industry sectors are
           primarily driven by the desire to gain market share and economies of
           scale.
           o   Computer Services (Diamond Technology Partners)
           o   Electronic Imaging (Eastman Kodak)
           o   Hardware (Gateway, Silicon Graphics)
           o   Internet Infrastructure (Verio, Winstar)
           o   Software (Legato Systems)
       -   Transportation: Airlines -- although mergers of major airlines are
           unlikely to occur anytime soon, certain major airlines may desire to
           acquire small regional feed carriers or much smaller jet operators in
           non-overlapping geographic regions. (Alaska Air Group, America West
           Holdings, Atlantic Coast Airlines)

       -   Utilities -- deregulation has resulted in rapid consolidation of this
           industry (CMS Energy, Energy East Corp.)



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
common stocks. For example:

   THE TRUST IS NOT "MANAGED"

   o   The Trust, unlike a mutual fund, is not "managed" and stocks will not be
       sold by the Trust to take advantage of market fluctuations.

   THE TRUST MAY SELL PORTFOLIO STOCKS

   o   Although the Trust is not managed, 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.


                                      A-5
<PAGE>

   o   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.

   o   If many investors sell their Units, the Trust will have to sell stocks.
       These sales could result in losses for the Trust and increase your share
       of Trust expenses.


   o   Due to merger and acquisition activity, as well as the reasons described
       above, the Trust may have to tender or sell stocks in the Trust
       Portfolio. If the Trust must tender or sell stocks for any of these
       reasons, such tenders or sales may reduce the diversification of your
       investment.


   THE PRICE AND VALUE OF UNITS WILL FLUCTUATE DURING THE TRUST'S TERM.

   o   The price of your Units depends upon the full range of economic and
       market influences including the prices of equity securities, the
       condition of the stock markets and other economic influences that affect
       the global or United States economy.

   o   Assuming no changes occur in the prices of the stocks held by the Trust,
       the price you paid for your Units will generally be less than the price
       you paid because your purchase price included a sales charge.

   o   The stocks in the Trust's Portfolio will generally trade on a domestic
       stock exchange or in the over-the-counter market. PaineWebber 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.

   o   Additional stocks may be purchased by the Trust when additional Units are
       offered to the public or for the Reinvestment Plan. Costs, such as
       brokerage fees, incurred in purchasing such additional stocks will be
       borne by the Trust. Your Units will be worth less as a result of the
       Trust's payment of these brokerage fees and other expenses.


THE INVESTMENT STRATEGY MAY NOT PRODUCE THE ANTICIPATED RESULTS.



2. RISKS OF INVESTING IN STOCKS

INVESTING ALWAYS INVOLVES RISKS. The risks described below are the most
significant risks associated with investing in the stocks held by the Trust.

   o   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.

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

   o   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, the financial condition of
       the issuers of stocks, changes in worldwide or national economic
       conditions, the prices of equity securities in general and the Trust's
       stocks in particular.

EXAMPLE

     This example may help you compare the cost of investing in the Trust to
the cost of investing in other funds.

     The example below assumes that you invest $10,000 in the Trust for the
periods indicated and then either redeem or do not redeem your Units at the end
of those periods. The example also assumes a 5% return on your investment each
year and that the Trust's annual operating expenses stay the same. Although
your actual costs may be higher or lower, based on these assumptions your costs
would be:


          1 YEAR          2 YEARS          3 YEARS
          ------          -------          -------
          $               $                $

     See "Expenses of the Trust" in Part B of this Prospectus for additional
information regarding expenses.


BRIEF DESCRIPTION OF THE TRUST'S INVESTMENT PORTFOLIO.

o   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 Part A of
    this Prospectus.


o   The "Schedule of Investments" in Part A of this Prospectus also identifies
    how each stock was selected in light of the Investment Strategy for the
    Trust.

IS THIS TRUST APPROPRIATE FOR YOU?

     Yes, if you are seeking capital appreciation over the life of the Trust by
investing in common stocks issued by companies which PaineWebber selected for
their growth potential. 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 investments or if you need current income.

- ----------
(1) The date prior to the Initial Date of Deposit.

(2) As of the close of business on the Initial Date of Deposit, the number of
    Units may be adjusted so that the Public Offering Price Per Unit will equal
    approximately $10.00, based on the 4:00 p.m. Eastern time valuation of the
    Stocks in the Portfolio on such date. Subsequently, to the extent of any
    such adjustment in the number of Units, the fractional undivided interest
    per Unit will increase or decrease accordingly, from the amounts indicated
    above.


(3) The Public Offering Price will be based upon the value of the stocks next
    computed following any purchase orders received plus the applicable sales
    charges and will vary on any date after      , 2000 from the Public Offering
    Price per Unit shown above. Following the Initial Date of Deposit, costs
    incurred in purchasing additional securities will be at the expense of the
    Trust. Any investor purchasing Units after the Initial Date of Deposit will
    also pay a proportionate share of any accumulated dividends in the Income
    Account. (See "Essential Information Regarding the Trust--Additional
    Deposits," "Risk Factors and Special Considerations" and "Valuation" in Part
    B of this Prospectus).

(4) The Initial Sales Charge is 1% per 100 Units. In addition, twelve (12)
    monthly Deferred Sales Charges of $2.50 per 100 Units (totalling $25.00 per
    100 Units) will be deducted from the Trust's net asset value on the tenth
    (10th) day of each month from month 8 ( ) through month 12 ( ) in both years
    one (1) and two (2) of the Trust's three year life. The Initial Sales Charge
    is reduced on purchases of Units worth $50,000 or more. See "Public Offering
    of Units--Sales Charge and Volume Discount" in Part B of this Prospectus.


(5) See "Distributions" in Part B of this Prospectus.

(6) Investors purchasing Units during the initial offering period will reimburse
    the Sponsor for all or a portion of the costs incurred by the Sponsor in
    connection with organizing the Trust and offering the Units for sale
    described more fully in "Public Offering Price" in Part B of this Prospectus
    (collectively, the "Initial Organizational Costs"). These costs have been
    estimated at $       per Unit based upon the expected number of Units to be
    created during the initial offering period. Certain Stocks purchased with
    the proceeds of the Public Offering Price will be sold by the Trustee at the
    completion of the initial public offering period to reimburse the Sponsor
    for Initial Organizational Costs actually incurred. If the actual Initial
    Organizational Costs are less than the estimated amount, only the actual
    Initial Organizational Costs will be deducted from the assets of the Trust.
    If, however, the amount of the actual Initial Organizational Costs are
    greater than the estimated amount, only the estimated amount of the Initial
    Organizational Costs will be deducted from the assets of the Trust.

(7) See "Expenses of the Trust" in Part B of this Prospectus. Estimated
    dividends from the stocks purchased, based upon last dividends actually
    paid, are expected by the Sponsor to be sufficient to pay estimated annual
    expenses of the Trust. If such dividends and income paid are insufficient to
    pay expenses, the Trustee is authorized to sell stocks in an amount
    sufficient to pay such expenses. (See "Administration of the Trust" and
    "Expenses of the Trust" in Part B of this Prospectus.)

*   The sales charge will not be assessed on stocks sold to reimburse the
    Sponsor for the Initial Organizational Costs.


**  This figure reflects deduction of the Initial Sales Charge of 1.00% and the
    Deferred Sales Charges for the first year of $ per Unit. As of the close of
    the initial offering period, the Redemption Value will be reduced to reflect
    the payment of Initial Organizational Costs (see "Summary of Risk Factors"
    and "Comparison of Public Offering Price and Redemption Value" in Part B of
    this Prospectus).

        THE UNITHOLDERS, SPONSOR AND TRUSTEE
        THE PAINEWEBBER EQUITY TRUST, GROWTH STOCK SERIES 25

- ----------
     (a) The aggregate cost to the Trust of the securities listed under
"Schedule of Investments" in this Prospectus Part A is determined by the
Trustee on the basis set forth under "Public Offering of Units--Public Offering
Price" in Part B of this Prospectus. See also the column headed "Cost of
Securities to Trust" under "Schedule of Investments" in this Prospectus Part A.
Pursuant to contracts to purchase securities, an irrevocable letter of credit
drawn on           in the amount of $     has been deposited with the Trustee,
Investors Bank & Trust Company, for the purchase of $       aggregate value of
Securities in the initial deposit and for the purchase of Securities in
subsequent deposits.

     (b) Investors purchasing Units during the initial offering period will
reimburse the Sponsor for all or a portion of the costs incurred by the Sponsor
in connection with organizing the Trust and offering the Units for sale as
described more fully in "Public Offering Price" in Part B of this Prospectus
(collectively, the "Initial Organizational Costs"). These costs have been
estimated at $     per Unit based upon the expected number of Units to be
created during the initial offering period. Certain stocks purchased with the
proceeds of the Public Offering Price will be sold by the Trustee at the
completion of the initial public offering period to reimburse the Sponsor for
Initial Organizational Costs actually incurred. If the actual Initial
Organizational Costs are less than the estimated amount, only the actual
Initial Organizational Costs will be deducted from the assets of the Trust. If,
however, the amount of the actual Initial Organizational Costs are greater than
the estimated amount, only the estimated amount of the Initial Organizational
Costs will be deducted from the assets of the Trust.

     (c) Because the value of stocks at the Evaluation Time on the Initial Date
of Deposit may differ from the amounts shown in this Statement of Net Assets,
the number of Units offered on the Initial Date of Deposit will be adjusted
from the initial number of Units shown to maintain the $10 per Unit offering
price only for that day. The Public Offering Price on any subsequent day will
vary.

     (d) The aggregate public offering price is computed on the basis set forth
under "Public Offering of Units--Public Offering Price" in Part B of this
Prospectus.


     (e) Assumes the maximum Initial Sales Charge of 1.00% of the Public
Offering Price. Additionally, ten (10) monthly Deferred Sales Charges of $2.50
per 100 Units (totalling $25.00 per 100 Units) will be deducted from the
Trust's net asset value on the tenth (10th) day of each month from month 8(  )
through month 12 (   ) in both years (1) and (2) of the Trust's three year
life. Distributions will be made to an account maintained by the Trustee from
which the Deferred Sales Charges obligation of the Unitholders to the Sponsor
will be met. If Units are sold, redeemed or exchanged prior to       , only the
balance of the Deferred Sales Charges remaining for the first year of the Trust
will be deducted. If Units are sold, redeemed or exchanged after       , the
remaining balance of the Deferred Sales Charges for the second year of the
Trust will be deducted. The sales charges are computed on the basis set forth
under "Public Offering of Units--Sales Charge and Volume Discount" in Part B of
this Prospectus. Based on the projected total assets of $      , the estimated
aggregate maximum Deferred Sales Charge in the aggregate would be $      .

- --------------------------------------------------------------------------------
                    THE COMPOSITION OF THE TRUST PORTFOLIO



     The objective of the PaineWebber Equity Trust, Growth Stock Series 25 (the
"Trust") is to provide for capital appreciation through an investment in equity
stocks which have, in the Sponsor's opinion on the Initial Date of Deposit, an
above-average potential for capital appreciation, because the issuers of such
stocks may be attractive candidates for acquisition. PaineWebber believes that
many companies present attractive opportunities to acquirors and on the Initial
Date of Deposit has identified issuers of stocks contained in the Trust as
potential candidates for acquisition. The Trust will seek to achieve its
objective of capital appreciation through an investment in a diversified
portfolio of such stocks. (Such stocks are referred to herein as the "Stocks"
or the "Securities".) OF COURSE, THERE CAN BE NO ASSURANCE THAT THE OBJECTIVE
OF THE TRUST WILL BE ACHIEVED.


     Additional Deposits. After the first deposit on the Initial Date of
Deposit the Sponsor may, from time to time, cause the deposit of additional
Securities ("Additional Securities") in the Trust where additional Units are to
be offered to the public. (See "The Trust" in Part B of this Prospectus). Costs
incurred in acquiring such Additional Securities 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 such deposits of
Additional Securities purchased by the Trustee with cash or cash equivalents
pursuant to instructions to purchase such Additional Securities. (See "The
Trust" and "Risk Factors and Special Considerations" in Part B of this
Prospectus.)


     Public Offering Price.  Units will be charged a combination of an Initial
Sales Charge on the date of purchase of 1.00% of the Public Offering Price,
plus Deferred Sales Charges which will aggregate $25.00 per 100 Units over the
first (1st) and second (2nd) years of the Trust's life. For example, on the
Initial Date of Deposit, on a $1,000 investment, $990.00 is invested in the
Trust and a $10.00 Initial Sales Charge is collected. In addition, a Deferred
Sales Charge of $2.50 per 100 Units will be deducted from the Trust's net asset
value on the tenth (10th) day of each month from month 8 (  ) through month 12
(   ) in both years one (1) and two (2) of the Trust's three year term, for a
total of $25.00. This deferred method of payment keeps more of the investor's
money invested over a longer period of time than would be the case if a single
sales charge of the same amount were collected on the initial date of purchase.
The sales charges are reduced on a graduated scale for volume purchasers and
are reduced for employees of the Sponsor. Units are offered at the Public
Offering Price computed as of the Evaluation Time for all sales subsequent to
the previous evaluation. The Public Offering Price on the Initial Date of
Deposit, and on subsequent dates, will vary from the Public Offering Price set
forth under "Essential Information Regarding the Trust" in Part A of this
Prospectus. Units redeemed or repurchased prior to the accrual of the final
Deferred Sales Charge installment may, depending upon the date of such
redemption or repurchase, have the amount of any remaining installments
deducted from the redemption or repurchase proceeds. (See "Public Offering of
Units" in Part B of this Prospectus.) In addition, during the initial public
offering period, the Public Offering Price will include an amount sufficient to
reimburse the Sponsor for the payment of all or a portion of the Initial
Organizational Costs described more fully in "Public Offering Price" in Part B
of this Prospectus.


     Distributions. The Stocks in the Trust were chosen for their potential for
capital appreciation, not for their income potential. The Trustee will make
distributions, on the Distribution Dates. (See


                                      B-1
<PAGE>

"Distributions" and "Administration of the Trust" in Part B of this
Prospectus.) Unitholders may elect to have their Income Account and Capital
Account distributions automatically reinvested into additional Units of the
Trust at no Initial Sales Charge (see "Reinvestment Plan" in Part B of this
Prospectus). (Such Units will be subject to the Deferred Sales Charges.) Upon
termination of the Trust, the Trustee will distribute to each Unitholder of
record on such date his pro rata share of the Trust's assets, less expenses.
The sale of Securities 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.


     Termination. Unitholders may receive their termination proceeds in cash
(or, at the Sponsor's election, in kind for distributions in excess of
$500,000) after the Trust terminates (see "Termination of the Trust" in Part B
of this Prospectus). Unless advised to the contrary by the Sponsor, the Trustee
will begin to sell the Securities held in the Trust twenty days prior to the
Mandatory Termination Date. Moneys held upon such sale or maturity of
Securities will be held in non-interest bearing accounts created by the
Indenture until distributed and will be of benefit to the Trustee. The Trust
will terminate approximately three years after the Initial Date of Deposit
regardless of market conditions at the time. (See "Termination of the Trust"
and "Federal Income Taxes" in Part B of this Prospectus.)


     Market for Units. The Sponsor, though not obligated to do so, presently
intends to maintain a secondary market for Units. The public offering price in
the secondary market will be based upon the value of the Securities next
determined after receipt of a purchase order, plus the applicable sales charge.
(See "Public Offering of Units--Public Offering Price" and "Valuation" in Part
B of this Prospectus.) If a secondary market is not maintained, a Unitholder
may dispose of his Units only through redemption. With respect to redemption
requests in excess of $500,000, the Sponsor may determine in its sole
discretion to direct the Trustee to redeem units "in kind" by distributing
Securities to the redeeming Unitholder. (See "Redemption" in Part B of this
Prospectus.)


THE TRUST

     The Trust is one of a series of similar but separate unit investment
trusts created under New York law by the Sponsor pursuant to a Trust Indenture
and Agreement* (the "Indenture") dated as of the Initial Date of Deposit,
between PaineWebber Incorporated, as Sponsor and Investors Bank & Trust
Company, as Trustee (the "Trustee"). The objective of the Trust is capital
appreciation through an investment principally in equity stocks having, in
Sponsor's opinion on the Initial Date of Deposit, potential for capital
appreciation. Of course, there can be no assurance that the objective of the
Trust will be achieved.


     On the Initial Date of Deposit, the Sponsor deposited with the Trustee
confirmations of contracts for the purchase of Stocks 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 receipt for Units representing the entire ownership of the Trust.

     With the deposit on the Initial Date of Deposit, the Sponsor established a
proportionate relationship between the Securities in the Trust (determined by
reference to the number of shares of each issue of



- ----------
* Reference is hereby made to such Trust Indenture and Agreement and any
statements contained in both Parts A and B of this Prospectus are qualified in
their entirety by the provisions of such Trust Indenture and Agreement.

Stock). 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
or pursuant to the Reinvestment Plan. During the 90-day period following the
Initial Date of Deposit, deposits of Additional Securities or cash in
connection with the issuance and sale of additional Units will maintain, to the
extent practicable, the original proportionate relationship among the number of
shares of each Security. 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 Security but which does not
affect the Trust's percentage ownership of the common stock equity of such
issuer at the time of such event, to reflect a merger or reorganization, to
reflect the acquisition of Securities or to reflect a sale or other disposition
of a Security. It may not be possible to maintain the exact original
proportionate relationship among the Securities deposited on the Initial Date
of Deposit because of, among other reasons, purchase requirements, changes in
prices, brokerage commissions or unavailability of Securities (see
"Administration of the Trust--Portfolio Supervision" in this Prospectus Part
B). Units may be continuously offered to the public by means of this Prospectus
(see "Public Offering Of Units--Public Offering Price" in this Prospectus Part
B) resulting in a potential increase in the number of Units outstanding.
Deposits of Additional Securities subsequent to the 90-day period following the
Initial Date of Deposit must replicate exactly the proportionate relationship
among the number of shares of each of the Securities comprising the Portfolio
immediately prior to such deposit of Additional Securities. Stock dividends
issued in lieu of cash dividends, if any, received by the Trust will be sold by
the Trustee and the proceeds therefrom shall be added to the Income Account.
(See "Administration of the Trust" and "Reinvestment Plan" in Part B of this
Prospectus).

     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" in Part A of this Prospectus.
However, if additional Units are issued by the Trust (through the deposit of
Additional Securities for purposes of the sale of additional Units or pursuant
to the Reinvestment Plan), 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" in Part B of this Prospectus.)

     The Stocks have been selected for their capital appreciation potential in
light of the Sponsor's opinion, on the Initial Date of Deposit, that the
issuers of such Stocks may be attractive acquisition candidates pursuant to
mergers, acquisitions and tender offers. In general, tender offers involve a
bid by an issuer or other acquiror to acquire a stock pursuant to the terms of
its offer. Payment generally takes the form of cash, securities (typically
bonds or notes), or cash and securities. Pursuant to federal law a tender offer
must remain open for at least 20 days and withdrawal rights apply during the
entire offering period. Frequently offers are conditioned upon a specified
number of shares being tendered and upon the obtaining of financing. There may
be other conditions to the tender offer as well. Additionally, an offeror may
only be willing to accept a specified number of shares. In the event a greater
number of shares is tendered, the offeror must take up and pay for a pro rata
portion of the shares deposited by each depositor during the period the offer
remains open.

     Because the Stocks have been selected with a view to potential
acquisition, the Indenture sets forth criteria to be applied in the event of a
tender offer, merger or reorganization. The Trust is not managed and has been
structured with certain automatic provisions contained in the Indenture. The
foregoing may



                                      B-3
<PAGE>


interfere with the Trust's ability to maximize its objectives and,
consequently, a Unitholder's value. In such case, Unitholders shall have no
rights against the Trust, the Sponsor, the Trustee or any other party
associated with the Trust. The foregoing is not a disclaimer of
responsibilities under Section 36 of the Investment Company Act of 1940.

     In the event the Trustee is notified of any vote to be taken or proposed
to be taken by holders of the Securities held by the Trust Fund in connection
with any proposed merger, reorganization, spin-off split-off or split-up by the
issuer of Securities held in the Trust Fund, the Trustee shall use its best
efforts to vote the Securities as closely as practicable in the same manner and
in the same general proportion as the Securities held by owners other than the
Trust Fund are voted. In the event that an offer shall be made by any person to
exchange stock or securities for any Securities (including but not limited to a
tender offer), the Trustee shall reject such offer.

     If stock or other securities are received by the Trustee, with or without
cash, as a result of any merger, reorganization, tender offer, spin-off,
split-off, or split-up by the issuer of Securities held in the Trust Fund or in
exchange for Securities (including any stock or securities received
notwithstanding the Trustee's rejection of an offer or received without an
initial offer), the Trustee, at the direction of the Sponsor, may retain or
sell such stock or securities in the Trust Fund. Any stock or securities so
retained shall be subject to the terms and conditions of the Indenture to the
same extent as the Securities originally deposited hereunder. The Trustee shall
give notice to the Unitholders of the retention of stock or securities acquired
in exchange for Securities within five Business Days after such acquisition.

     Additional shares of Securities received as a distribution on Securities
(other than shares received in a non-taxable distribution which shall be
retained by the Trust Fund) shall be sold and the proceeds credited to the
Income Account.

     There is no guarantee that there will be a tender offer for any of the
Stocks, or merger or acquisition of any of the issuers whose stock is contained
in the Trust. In addition, it is possible that legislation or regulations
affecting merger and acquisition activity in the future may be passed and, if
passed, the Sponsor cannot predict the impact upon the Trust. There is also no
guarantee that the price received upon sale or pursuant to an acquisition will
be the best price which could be received by the Trust at any time. For
example, after stock is sold, the value may increase due to general market
factors or due to subsequent tender offers. Additionally, the price of a Stock
may decline for Stocks not taken up pursuant to a tender offer or in the event
a merger or acquisition is not completed.


     INVESTORS SHOULD BE AWARE THAT THE TRUST, UNLIKE A MUTUAL FUND, IS NOT A
"MANAGED" FUND AND AS A RESULT THE ADVERSE FINANCIAL CONDITION OF A COMPANY
WILL NOT RESULT IN ITS ELIMINATION FROM THE PORTFOLIO EXCEPT UNDER CERTAIN
LIMITED CIRCUMSTANCES (SEE "TRUST ADMINISTRATION--PORTFOLIO ADMINISTRATION" IN
PART B OF THIS PROSPECTUS). IN ADDITION, SECURITIES WILL NOT BE SOLD BY THE
TRUST TO TAKE ADVANTAGE OF MARKET FLUCTUATIONS OR CHANGES IN ANTICIPATED RATES
OF APPRECIATION.

     Investors should note that PaineWebber, in its general securities
business, acts as agent or principal in connection with the purchases and sales
of equity securities, including the Securities in the Trust, and may act as a
market maker in certain of the Securities. PaineWebber also from time to time
issues reports and may make recommendations relating to equity securities,
including the Securities in the Trust, and has provided, and may continue to
provide, investment banking services to the issuers of the Securities.

     Investors should note in particular that the Securities were selected by
the Sponsor as of the Initial Date of Deposit. The Trust may continue to
purchase Additional Securities when additional Units are offered to the public
or pursuant to the Reinvestment Plan, or may continue to hold Securities
originally


                                      B-4
<PAGE>

selected through this process. This may be the case even though the evaluation
of the attractiveness of such Securities may have changed and, if the
evaluation were performed again at that time, the Securities would not be
selected for the Trust. In addition, the Sponsor may continue to sell Trust
Units even if PaineWebber changes a recommendation relating to one or more
Securities in the Trust.

RISK FACTORS AND SPECIAL CONSIDERATIONS

     An investment in Units of the Trust should 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.

     The Trust is not appropriate for investors who require high current income
or seek conservation of capital.

     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 in the Trust may be
expected to fluctuate over the life of the Trust.

     In addition, there are investment risks common to all equity issues. The
Stocks may appreciate or depreciate in value depending upon a variety of
factors, including the full range of economic and market influences affecting
corporate profitability, the financial condition of issuers, changes in
national or worldwide economic conditions, and the prices of equity securities
in general and the Stocks in particular. Distributions of income, generally
made by declaration of dividends, is also dependent upon several factors,
including those discussed above in the preceding sentence.

     Certain of the Stocks in the Trust may be ADRs which are subject to
additional risks. (See "Schedule of Investments" in Part A of this Prospectus.)
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 found in
stocks issued by domestic issuers. These investment risks include potential
political and economic developments, 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
U.S. securities laws and therefore may make less information publicly available
than that provided by domestic issuers.


                                      B-5
<PAGE>

Further, foreign issuers are not necessarily subject to uniform financial
reporting, auditing and accounting standards and practices which are applicable
to publicly traded 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 principally 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 then in
effect. 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 the
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, who make assessments of 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.

     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 Additional Securities in amounts and in percentage
relationships described above under "The Trust." To the extent the price of a
Security increases or decreases between the time cash is deposited with
instructions to purchase the Additional Security and the time the cash is used
to purchase the Additional Security, Units will represent less or more of that
Security and more or less of the other Securities in the Trust. Unitholders
will be at risk because of price fluctuations during this period since if the
price of shares of a Security increases, Unitholders will have an interest in
fewer shares of that Security, and if the price of a Security decreases,
Unitholders will have an interest in more shares of that Security, than if the
Security had been purchased on the date cash was deposited with instructions to
purchase the Security. In order to minimize these effects, the Trust will
attempt to purchase Additional Securities as closely as possible to the
Evaluation Time or at prices as closely as possible to the prices used to
evaluate the Trust at the Evaluation Time. Thus price fluctuations during this
period will affect the value of every Unitholder's Units and the income per
Unit received by the Trust. In addition, costs incurred in connection with the
acquisition of Additional Securities will be at the expense of the Trust and
will affect the value of every Unitholder's Units.

     In the event a contract to purchase a Stock to be deposited on the Initial
Date of Deposit or any other date fails, cash held or available under a letter
or letters of credit, attributable to such failed contract may be reinvested in
another stock or stocks having characteristics sufficiently similar to the
Stocks originally deposited (in which case the original proportionate
relationship shall be adjusted) or, if not so reinvested,


                                      B-6
<PAGE>

distributed to Unitholders of record on the last day of the month in which the
failure occurred. The distribution will be made twenty days following such
record date and, in the event of such a distribution, the Sponsor will refund
to each Unitholder the portion of the sales charge attributable to such failed
contract.

     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, OR ACQUIRE NEW SECURITIES, ONLY UNDER LIMITED
CIRCUMSTANCES. (SEE THE DISCUSSION BELOW RELATING TO DISPOSITION OF STOCKS
WHICH MAY BE THE SUBJECT OF A TENDER OFFER, MERGER OR REORGANIZATION UNDER THE
CAPTION "ADMINISTRATION OF THE TRUST--PORTFOLIO SUPERVISION" IN PART B OF THIS
PROSPECTUS.)


     A number of the Securities in the Trust may also be owned by other clients
of the Sponsor. However, because these clients may have investment objectives
which differ from that of the Trust, the Sponsor may sell certain Securities
from such clients' accounts in instances where a sale of such Securities by the
Trust would be impermissible, such as to maximize return by taking advantage of
attractive market fluctuations in such Securities. As a result, the amount
realized upon the sale of the Securities from the Trust may not be the highest
price attained for an individual Security during the life of the Trust.


     The Sponsor may have acted as underwriter, manager, or co-manager of a
public offering of the Securities deposited into the Trust on the Initial Date
of Deposit, or as an adviser to one or more of the issuers of the Securities,
during the last three (3) years. The Sponsor or affiliates of the Sponsor may
serve as specialists in the Securities on one or more stock exchanges and may
have a long or short position in any of these Securities or in options on any
of them, and may be on the opposite sides of public orders executed on the
floor of an exchange where the Securities are listed. The Sponsor may trade for
its own account as an odd-lot dealer, market maker, block positioner and/or
arbitrageur in any of the Securities or options on them. The Sponsor, its
affiliates, directors, elected officers and employee benefits programs may have
either a long or short position in any of the Securities or in options on them.



     The Sponsor does not know of any pending litigation as of the Initial Date
of Deposit that might reasonably be expected to have a material adverse effect
on the Portfolio, although pending litigation may have a material adverse
effect on the value of Securities in the Portfolio. In addition, at any time
after the Initial Date of Deposit, litigation may be initiated on a variety of
grounds, or legislation may be enacted, affecting the Securities in the
Portfolio or the issuers of such Securities. Changing approaches to regulation
may have a negative impact on certain companies represented in the Portfolio.
There can be no assurance that future litigation, legislation, regulation or
deregulation will not have a material adverse effect on the Portfolio or will
not impair the ability of issuers of the Securities to achieve their business
goals.


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. Each Unitholder will be considered to have received all of
     the dividends paid on such Unitholder's pro rata portion of each Security
     when such dividends are received by the Trust, whether or not such
     dividends are used to pay a portion of Trust expenses or whether they are
     automatically reinvested in additional Trust Units (see "Reinvestment Plan"
     in this Prospectus Part B).



                                      B-7
<PAGE>


         2. Each Unitholder will have a taxable event when the Trust disposes of
     a Security (whether by sale, exchange, or other disposition) 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 United States
Treasury Regulations (established under the Code) 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 applicable to non-U.S. investors is not addressed in this Prospectus.
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 his or her 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 gains or losses upon dispositions of Securities by the Trust and a pro
rata share of the expenses of the Trust.

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

     To the extent distributions with respect to a Stock were to exceed the
issuing corporation's current and accumulated earnings and profits, they would
not constitute dividends. Rather, they would be treated as a tax free return of
capital and would reduce a Unitholder's tax cost for such Stock. This reduction
in basis would increase any gain, or reduce any loss, realized by the
Unitholder on any subsequent sale or other disposition of such stock or 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 the sale of 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 further exceed amounts distributed to
the extent amounts are used by the Trust to pay expenses.

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

     Unitholders will be taxed in the manner discussed above regardless of
whether distributions from the Trust are actually received by the Unitholder in
cash or are reinvested pursuant to the "Reinvestment Plan" described later in
this Prospectus Part B. Unitholders exercising the Exchange Option may also
experience certain adverse tax consequences as described in the "Exchange
Option" described later in this Prospectus Part B.

     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



                                      B-8
<PAGE>


provided in Sections 246 and 246A of the Code. The dividends-received deduction
generally equals 70 percent of the amount of the dividend. As a result, the
maximum effective tax rate on dividends received generally will be reduced from
35 percent to 10.5 percent. A portion of the dividends-received deduction may,
however, be subject to the alternative minimum tax. Individuals, partnerships,
trusts, S corporations and certain other entities are not eligible for the
dividends-received deduction.


PUBLIC OFFERING OF UNITS

     Public Offering Price. The public offering price per Unit is based on the
aggregate market value of the Securities, next determined after the receipt of
a purchase order, divided by the number of Units outstanding plus the sales
charge set forth below. The public offering price per Unit is computed by
dividing the Trust Fund Evaluation, next determined after receipt of a purchase
order by the number of Units outstanding plus the sales charge. (See
"Valuation" in Part B of this Prospectus.) The Public Offering Price on the
Initial Date of Deposit or on any subsequent date will vary from the Public
Offering Price calculated on the business day prior to the Initial Date of
Deposit (as set forth under "Essential Information Regarding the Trust" in Part
A of this Prospectus) due to fluctuations in the value of the Stocks among
other factors. In addition, during the initial public offering period, a
portion of the Public Offering Price also consists of an amount sufficient to
reimburse the Sponsor for the payment of all or a portion of the Initial
Organizational Costs in the amount shown as a per Unit amount under "Essential
Information Regarding the Trust" in Part A of this Prospectus. The Initial
Organizational Costs include the cost of preparing the registration statement,
trust documents and closing documents for the Trust, registering with the
Securities and Exchange Commission (the "SEC") and the 50 States, the initial
fees of the Trustee's and Sponsor's counsel, and the initial audit of the
Trust's portfolio. The sales charge will not be assessed on those Securities
held in the Trust and sold by the Trustee at the end of the public offering
period to reimburse the Sponsor for the Initial Organizational Costs. See
"Administration of the Trust--Accounts" in Part B of this Prospectus for a
description of the method by which the Trustee will sell such Securities.


     Sales Charge and Volume Discount. Subject to variations discussed below,
Units will be charged a Total Sales Charge of 3.50% per 100 Units which is a
combination of the Initial and Deferred Sales Charges. The Initial Sales Charge
will be 1.00% of the Public Offering Price. In the first year, assuming a
purchase on the Initial Date of Deposit of 100 Units, the Initial Sales Charge
will be $10.00. Commencing in the eighth (8th) month of the Trust's first year
(  ) and continuing through the the twelfth (12th) month of the Trust's first
year (   ) and then commencing again in the eighth (8th) month of the Trust's
second year (  ) and continuing through the twelfth (12th) month of the Trust's
second year (   ), the Deferred Sales Charge per 100 Units will be $12.50 per
year, approximately 1.25% of the Public Offering Price. Because the Deferred
Sales Charge per 100 Units is $12.50 per year for the first two years of the
Trust, regardless of the price paid for Units, the Total Sales Charges
expressed as a percentage of the Public Offering Price will vary with the price
you pay to purchase Units. So, for example, if you buy 100 Units for $1,000
(including the Initial Sales Charge of $10.00 and hold the Units until the
Trust terminates, you will pay a Total Sales Charge of $35.00 or 3.50% of the
acquisition price for such Units. If, however, you buy 100 Units for $950.00
(including the Initial Sales Charge of $9.50), you will pay a Total Sales
Charge of $34.50 or 3.63% of the acquisition price for such Units. Conversely,
if an investor bought 100 Units for $1,100 (including the Initial Sales Charge
of $11.00), such investor would pay a total of $36.00 or 3.30% of the
acquisition price for such Units.

     The monthly Deferred Sales Charge is a charge of $2.50 per 100 Units and
is accrued in five (5) installments each year of the Trust during the first
(1st) and second (2nd) full years of the three year term



                                      B-9
<PAGE>


of the Trust ($12.50 annual total). Units purchased after an accrual date for a
Deferred Sales Charge installment are not subject to any Deferred Sales Charge
installments prior to such purchase date. Units redeemed or repurchased prior
to the accrual of the final Deferred Sales Charge installment will have the
amount of any installments remaining deducted from the redemption or repurchase
proceeds, although this deduction will be waived in the event of death or
disability (as defined in the Internal Revenue Code) of an investor. If Units
are sold, redeemed or exchanged prior to [     ], only the balance of the
Deferred Sales Charges remaining for the first year of the Trust will be
deducted. If Units are sold, redeemed or exchanged on or after [     ], the
remaining balance of the Deferred Sales Charges for the second year of the
Trust will be deducted.

     The Deferred Sales Charge will be accrued on the books of the Trust and
will be paid to the Sponsor upon the Sponsor's request. The Trustee is directed
to sell Securities to make this payment. It is anticipated that the Securities
will not be sold to pay the Deferred Sales Charges until after the date of the
final installment in the first and second years of the Trust. Investors will be
at risk for market price fluctuations in the Securities from the several
installment accrual dates to the dates of actual sales of Securities to satisfy
this liability.


     A discount in the sales charge is available to volume purchasers of Units
due to economies of scale 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 as set forth below for sales made on a single
day to any person of at least $50,000 or 5,000 Units, applied on whichever
basis is more favorable to the purchaser.

* The Initial Sales Charge applicable to volume purchasers according to the
  table above will be applied either on a dollar or Unit basis, depending upon
  which basis provides a more favorable purchase price to the purchaser.

     The volume discount on the Initial 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 NOT be
aggregated with concurrent purchases of any other trust which may be offered by
the Sponsor. Units held in the name of the purchaser's spouse or in the name of
a purchaser's child under the age of 21 are deemed for the purposes hereof to
be registered in the name of the purchaser. The reduced Initial Sales Charges
are also applicable to a trustee or other fiduciary purchasing Units for a
single trust estate or single fiduciary account.


                                      B-10
<PAGE>

     No Initial Sales Charge will be imposed on Units of the Trust acquired by
Unitholders in connection with participation in the Reinvestment Plan (see
"Reinvestment Plan" in Part B of this Prospectus).


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

     Exchange Option. Unitholders may elect to exchange any or all of their
Units of this Growth Stock Series of the PaineWebber Equity Trust for units of
one or more of any series of PaineWebber Municipal Bond Fund (the "PaineWebber
Series"); The Municipal Bond Trust (the "National Series"); The Municipal Bond
Trust, Multi-State Program (the "Multi-State Series"); The Municipal Bond
Trust, California Series (the "California Series"); The Corporate Bond Trust
(the "Corporate Series"); PaineWebber Pathfinder's Trust (the "Pathfinder's
Trust"); the PaineWebber Federal Government Trust (the "Government Series");
The Municipal Bond Trust, Insured Sales (the "Insured Series"); or the
PaineWebber Equity Trust (the "Equity Series") (collectively referred to as the
"Exchange Trusts"), at a Public Offering Price for the Units of the Exchange
Trusts to be acquired based on a reduced sales charge as discussed below.
Unitholders of this Trust are not eligible for the Exchange Option into any
Exchange Trust designated as a rollover series for the 30 day period prior to
termination of such Exchange Trust. The purpose of such reduced sales charge is
to permit the Sponsor to pass on the Unitholder who wishes to exchange Units
the cost savings resulting from such exchange of Units. The cost savings result
from reductions in time and expense related to advice, financial planning and
operational expenses required for the Exchange Option.

     Each Exchange Trust has different investment objectives, therefore a
Unitholder should read the prospectus for the applicable exchange trust
carefully prior to exercising this option. Exchange Trusts having as their
objective the receipt of tax-exempt interest income would not be suitable for
tax-deferred investment plans such as Individual Retirement Accounts. A
Unitholder who purchased Units of this Growth Stock Series and paid the Initial
Sales Charge and any Deferred Sales Charges that, in total, was an amount less
than the per Unit, per 100 Unit or per 1,000 Unit sales charge of the series of
the Exchange Trusts for which such Unitholder desires to exchange into, will be
allowed to exercise the Exchange Option at the Unit Offering Price plus the
reduced sales charge, provided the Unitholder has held the Units for at least
five months. Any such Unitholder who has not held the Units to be exchanged for
the five-month period will be required to exchange them at the Unit Offering
Price plus a sales charge based on the greater of the reduced sales charge, or
an amount which, together with the initial sales charge paid in connection with
the acquisition of the Units being exchanged, equals the sales charge of the
series of the Exchange Trust for which such Unitholder desires to exchange
into, determined as of the date of the exchange. Owners of Units of this Growth
Stock Series electing to use the Exchange Option in connection with units of
other Exchange Trusts subject to a deferred sales charge ("Deferred Sales
Charge Units") will be permitted to acquire Deferred Sales Charge Units, at
their then-current net asset value, with no Initial Sales Charge imposed.
Deferred Sales Charge Units acquired through the Exchange Option will continue
to be subject to the deferred sales charge installments remaining on those
Deferred Sales Charge Units so acquired.

     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 Growth Stock 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



                                      B-11
<PAGE>


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. Any excess proceeds from Unitholders'
Units being surrendered will be returned. Unitholders will be permitted to
advance new money in order to complete an exchange to round up to the next
highest number of Units.

     An exchange of units pursuant to the Exchange Option will normally
constitute a "taxable event" under the Code, i.e., a Unitholder will recognize
a tax gain or loss. Unitholders are advised to consult their own tax advisors
as to the tax consequences of exchanging units in their particular case.

     The Sponsor reserves the right to modify, suspend or terminate this plan
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 of this series to purchase units of one or more of the
Exchange Trusts. If units of the applicable outstanding series of the Exchange
Trust are at that time available for sale, and if such units may lawfully be
sold in the state in which the Unitholder is resident, the Unitholder may
select the series or group of series for which he desires his investment to be
exchanged. The Unitholder will be provided with a current prospectus or
prospectuses relating to each series in which he indicates interest.

     The exchange transaction will operate in a manner essentially identical to
any secondary market transaction, i.e., Units will be repurchased at a price
based on the aggregate bid price per Unit of the securities in the portfolio of
the Trust. Units of the Exchange Trust, however, will be sold to the Unitholder
at a reduced sales charge as discussed above. 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.

     Conversion Option. Owners of units of any registered unit investment trust
sponsored by others 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 ("Conversion Trust Units")
directly to acquire available units of any Exchange Trust having an up-front
sales load at a reduced sales charge of $15 per Unit, 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). Owners of Conversion
Trust Units will be permitted to use the cash proceeds received from the sale
or redemption of those units to acquire units of this Growth Stock Series, or
any other Deferred Sales Charge Units, at their then-current net asset value,
with no Initial Sales Charge imposed. Deferred Sales Charge Units acquired
through the Conversion Option will continue to be subject to the deferred sales
charge installments remaining on those Deferred Sales Charge Units so acquired.
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 the
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 with notice, including the right to
increase the reduced sales charge applicable to this option (but not in excess
of $5 more per Unit, 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 herein.


                                      B-12

<PAGE>


     Distribution of Units. The minimum purchase in the initial public offering
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 $18 per 100
Units in the first year, and $10 per 100 Units in the second year, of the
Trust, (a concession of 80% of the Total Sales Charge during the first and
second years of the Trust) subject to change from time to time. Volume
incentives can be earned as a marketing allowance by "Eligible Dealer Firms"
who reach cumulative firm sales or sales arrangement levels of a specified
dollar amount of the PaineWebber Equity Trust Growth Stock Series 25 sold in
the primary market (the "Incentive Period"), as set forth in the table below.
Eligible Dealer Firms are dealers that are providing marketing support for
PaineWebber unit trusts in the form of distributing or permitting the
distribution of marketing materials and other product information. Eligible
Dealer Firms will not include firms that solely provide clearing services to
broker/dealer firms. For firms that meet the necessary volume level, volume
incentives may be given on all trades involving Growth Stock Series 25
originated from client accounts only, during the Incentive Period.

</TABLE>



     Only sales through the Sponsor qualify for volume incentives and for
meeting minimum requirements. The Sponsor reserves the right to modify or
change the volume incentive schedule at any time and make the determination as
to which firms qualify for the marketing allowance and the amount paid. The
difference between the sales charge and the dealer concession will be retained
by the Sponsor. In the event that the dealer concession is 90% or more of the
sales charge per Unit, dealers taking advantage of such concession may be
deemed to be underwriters under the Securities Act of 1933.


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

     Secondary Market for Units. While not obligated to do so, the Sponsor
intends to maintain a secondary market for the Units and continuously offer to
purchase Units at the Trust Fund Evaluation per Unit next computed after
receipt by the Sponsor of an order from a Unitholder. The Sponsor may cease to
maintain such a market at any time, and from time to time, without notice. In
the event that a secondary market for the Units is not maintained by the
Sponsor, a Unitholder desiring to dispose of Units may tender such Units to the
Trustee for redemption at the price calculated in the manner set forth under
"Redemption" in Part B of this Prospectus. Redemption requests in excess of
$500,000 may be redeemed "in kind" as described under "Redemption." The Sponsor
does not in any way guarantee the enforceability, marketability, value or price
of any of the stocks in the Trust, nor that of the Units.

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

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


                                      B-13
<PAGE>

     A Unitholder who wishes to dispose of his Units should inquire of his bank
or broker as to current market prices in order to determine if over-the-counter
prices exist in excess of the redemption price and the repurchase price (see
"Redemption" in Part B of this Prospectus).

     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 Stocks to the Sponsor and the price at which it deposits the
Stocks in the Trust in exchange for Units, which is the value of the Stocks,
determined by the Trustee as described under "Valuation" in Part B of this
Prospectus. The cost of Stock to the Sponsor includes the amount paid by the
Sponsor for brokerage commissions. These amounts are an expense of the Trust.

     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 the period. In
maintaining a secondary market for the Units, the Sponsor may realize profits
or sustain losses in the amount of any differences between the price at which
it buys Units and the price at which it resells or redeems such Units.

REDEMPTION

     Units may be tendered to Investors Bank & Trust Company for redemption at
its office in person, or by mail at 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 Trustee, but any remaining
Deferred Sales Charge installments will be deducted at that time. A written
instrument of redemption must be signed by the Unitholder. Unitholders must
sign exactly as their names appear on the records of the Trustee with
signatures guaranteed by an eligible guarantor institution or in such other
manner as may be acceptable to the Trustee. In certain instances the Trustee
may require additional documents such as, but not limited to, trust
instruments, certificates of death, appointments as executor or administrator,
or certificates of corporate authority. Unitholders should contact the Trustee
to determine whether additional documents are necessary. Units tendered to the
Trustee for redemption will be cancelled, if not repurchased by the Sponsor.

     Units will be redeemed at the Redemption Value per Unit next determined
after receipt of the redemption request in good order by the Trustee. The
Redemption Value per Unit is determined by dividing the Trust Fund Evaluation
by the number of Units outstanding. (See "Valuation" in Part B of this
Prospectus) Unitholders who redeem prior to the accrual of the final Deferred
Sales Charges installment, may, depending upon the date of such redemption,
have the amount of any installments remaining deducted from their redemption
proceeds or deducted in calculating an in-kind redemption, although this
deduction will be waived in the event of death or disability (as defined in the
Internal Revenue Code) of an investor (see "Public Offering of Units" in Part B
of this Prospectus).


     A redemption request is deemed received on the business day (see
"Valuation" in Part B of this Prospectus for a definition of business day) when
such request is received prior to the closing time of the regular trading
session on the New York Stock Exchange, Inc. (ordinarily 4:00 p.m. New York
time). If it is received after that time, it is deemed received on the next
business day. During the period in which



                                      B-14
<PAGE>

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 business day following such presentation and
Unitholders will receive the Redemption Value next determined after receipt by
the Trustee of the redemption request. Proceeds of a redemption will be paid to
the Unitholder no later than 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 and for remaining amounts, from the Capital Account. The Trustee
is empowered, to the extent necessary, to sell Securities to meet redemptions.
The Trustee will sell Securities in such manner as is directed by the Sponsor.
In the event no such direction is given. Stocks will be sold pro rata, to the
extent possible, and if not possible, the Trustee may designate Securities to
be sold. (See "Administration of the Trust" in Part B of this Prospectus.)
However, with respect to redemption requests in excess of $500,000, the Sponsor
may determine in its sole discretion to direct the Trustee to redeem Units "in
kind" by distributing Stocks to the redeeming Unitholder. When Stocks are so
distributed, a proportionate amount of each 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" in Part B of this Prospectus. A Unitholder receiving a redemption
"in kind" may incur brokerage or other transaction costs in converting the
Stocks distributed into cash. The availability of redemption "in kind" is
subject to compliance with all applicable laws and regulations, including the
Securities Act of 1933.

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

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

VALUATION

     The Trustee will calculate the Trust's value (the "Trust Fund Evaluation")
per Unit at the Evaluation Time set forth under "Essential Information
Regarding the Trust" in Part A of this Prospectus (1) on each business day as
long as the Sponsor is maintaining a bid in the secondary market, (2) on the
business day on which any Unit is tendered for redemption, (3) on any other day
desired by the Sponsor or the Trustee


                                      B-15
<PAGE>

and (4) upon termination, by adding (a) the aggregate value of the Securities
and other assets determined by the Trustee as set forth below, (b) cash on hand
in the Trust, including dividends receivable on Stock trading ex-dividend and
income accrued held but not yet distributed (other than any cash held in any
reserve account established under the Indenture or cash held for the purchase
of Contract Securities) and (c) accounts receivable for Securities sold and any
other assets of the Trust not included in (a) and (b) above, and deducting
therefrom the sum of (v) taxes or other governmental charges against the Trust
not previously deducted, (w) accrued fees and expenses of the Trustee and the
Sponsor (including legal and auditing expenses), other Trust expenses and any
accrued Deferred Sales Charge installment not yet paid to the Sponsor (x) cash
allocated for distributions to Unitholders and amounts owed to the Sponsor in
reimbursement of Initial Organizational Costs and (y) accounts payable for
Units tendered for redemption and any other liabilities of the Trust Fund not
included in (v), (w), (x) and (y) above. The per Unit Trust Fund Evaluation is
calculated by dividing the result of such computation by the number of Units
outstanding as of the date thereof. Business days do not include Saturdays,
Sundays, New Year's Day, Martin Luther King, Jr. 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 domestic Stocks are listed on one or more
national securities exchanges or on the National Market System maintained by
the National Association of Securities Dealers Automated Quotations System,
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 in the case of the domestic Stocks if such Stocks are listed thereon),
(2) if there is no such appropriate closing sales price on such exchange or
system, at the mean between the closing bid and asked prices on such exchange
or system (unless the Trustee deems such price inappropriate as a basis for
evaluation), (3) if the Stocks are not so listed or, if so listed and the
principal market therefor is other than on such exchange or there are no such
appropriate closing bid and asked prices available, such evaluation shall be
made by the Trustee in good faith based on the closing sale price in 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 Stock in good faith on the bid side
of the market or (d) by any combination thereof. The tender of a Stock pursuant
to a tender offer will not affect the method of valuing such Stock.

COMPARISON OF PUBLIC OFFERING PRICE AND REDEMPTION VALUE

     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 Initial Sales Charge) exceeded the Redemption Value. (See
"Essential Information Regarding the Trust" in Part A of this Prospectus). The
prices of Stocks are 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. Also, as of the close of the initial
public offering period, the Redemption Value per Unit will be reduced to
reflect the sale of Securities made to reimburse the Sponsor for the Initial
Organizational Costs.

EXPENSES OF THE TRUST

     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 $      per
Unit per calendar year, 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 Equity 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 $.0170 per Unit, based on the largest number of
Units outstanding during the previous month. In addition, the regular and
recurring expenses of the Trust are estimated to be $      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
the 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" in Part B of this Prospectus): (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 Trust and
the rights and interests of the Unitholders; (5) indemnification of the Trustee
for any loss, liabilities or expenses incurred by it in the administration of
the Trust without gross negligence, bad faith or wilful misconduct on its part;
(6) brokerage commissions and other expenses incurred in connection with the
purchase and sale of Securities; and (7) expenses incurred upon termination of
the Trust. In addition, to the extent then permitted by the Securities and
Exchange Commission, the Trust may incur expenses of maintaining registration
or qualification of the Trust or the Units under Federal or state securities
laws so long as the Sponsor is maintaining a secondary market (including, but
not limited to, legal, auditing and printing expenses).

     The accounts of the Trust shall be audited not less than annually by
independent public accountants selected by the Sponsor. The expenses of the
audit shall be an expense of the Trust. So long as the Sponsor maintains a
secondary market, the Sponsor will bear any annual audit expense which exceeds
$.0050 per Unit. Unitholders covered by the audit during the year may receive a
copy of the audited financial statements 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 entire amount of 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 to meet the expenses of the Trust. Securities will be selected in
the same manner as is set forth under "Redemption" in Part B of this
Prospectus.

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.


                                      B-17
<PAGE>

DISTRIBUTIONS

     The Trustee will distribute net dividends and interest, if any, from the
Income Account on the quarterly Distribution Dates to Unitholders of record on
the preceding Record Date. Distributions from the Capital Account will be made
on annual Distribution Dates to Unitholders of record on the preceding Record
Date. Distributions of less than $.0500 per Unit need not be made from the
Capital Account on any Distribution Date. See "Essential Information Regarding
the Trust" in Part A of this Prospectus. Whenever required for regulatory or
tax purposes, the Trustee will make special distributions of any dividends or
capital on special Distribution Dates to Unitholders of record on special
Record Dates declared by the Trustee.

     If and to the extent that the Sponsor, on behalf of the Trust, receives a
favorable response to a no-action letter request which it intends to submit to
the Division of Investment Management of the SEC with respect to reinvesting
cash proceeds received by the Trust, the Trustee may reinvest such cash
proceeds in Additional Securities held in the Trust Fund at such time. Such
reinvestment shall be made so that each deposit of Additional Securities shall
be made so as to match as closely as practicable the percentage relationships
of shares of Stocks and such reinvestment shall be made in accordance with the
parameters set forth in the no-action letter response. If the Sponsor and the
Trustee determine that it shall be necessary to amend the Indenture to comply
with the parameters set forth in the no-action letter response, such documents
may be amended without the consent of Unitholders. There can be no assurance
that the Sponsor will receive a favorable no-action letter response.

     Unitholders may elect to have their Income Account and Capital Account
distributions automatically reinvested into additional Units of the Trust at no
Initial Sales Charge. (See "Reinvestment Plan" in Part B of this Prospectus).

     Upon termination of the Trust, each Unitholder of record on such date will
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 of the Trust" in Part B of this Prospectus.)

REINVESTMENT PLAN

     Income Account and Capital Account distributions on Units may be
reinvested by participating in the Trust's Reinvestment Plan (the "Reinvestment
Plan" in Part B of this Prospectus). To participate in the Reinvestment Plan, a
Unitholder must contact his broker, dealer or financial institution to
determine whether he may participate in the Reinvestment Plan. Under the
Reinvestment Plan, the Units acquired for current Unitholders will be either
Units already held in inventory by the Sponsor or new Units created by the
Sponsor's deposit of Additional Securities, contracts to purchase Additional
Securities or cash (or a bank letter of credit in lieu of cash) with
instructions to purchase Additional Securities. Deposits or purchases of
additional Securities will be made so as to maintain the percentage
relationships of shares of Stocks, except as discussed under "The Trust" in
Part B of this Prospectus. Purchases made pursuant to the Reinvestment Plan
will be made without any Initial Sales Charge at the net asset value for Units
of the Trust; of course, such Units will be subject to the Deferred Sales
Charges remaining on Units purchased. Under the Reinvestment Plan, the Trust
will pay the distributions to the Trustee which in turn will purchase for those
participating Unitholders whole Units of the Trust at the price determined as
of the close of business on the Distribution Date and will add such Units to
the Unitholder's account. The Unitholder's account statement will reflect the
reinvestment. The Trustee will not issue fractional Units, thus any cash
remaining after purchasing the maximum number of whole Units will be
distributed to the


                                      B-18
<PAGE>

Unitholder. Unitholders wishing to terminate their participation in the
Reinvestment Plan must notify their broker, dealer or financial institution of
such decision. The Sponsor reserves the right to amend, modify or terminate the
Reinvestment Plan at any time without prior notice.

ADMINISTRATION OF THE TRUST

     Accounts. All dividends and interest received on Securities, proceeds from
the sale of Securities or other moneys received by the Trustee on behalf of the
Trust may 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 dividends, if
any, and interest income, on Securities in the Trust. All other receipts (i.e.,
return of principal 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" in Part B of this Prospectus.

     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" in Part B of this Prospectus)

     In addition, distributions of amounts necessary to pay (1) the Initial
Organizational Costs and (2) the Deferred Sales Charges will be made from the
Income Account and, to the extent funds are not sufficient therein, from the
Capital Account, to special accounts maintained by the Trustee for purposes of
(1) reimbursing the Sponsor and (2) satisfying Unitholders' Deferred Sales
Charges obligations, respectively. To the extent that funds are not available
in the Capital Account to meet certain charges or expenses, the Trustee may
sell Securities. Upon notification from the Sponsor that the initial offering
period is terminated, the Trustee, at the direction of the Sponsor, will cause
the sale of Securities in an amount equal to the Initial Organizational Costs
as certified to it by the Sponsor. Although the Sponsor may collect the
Deferred Sales Charges monthly, currently the Sponsor does not anticipate sales
of Securities to pay such sales charges until after              and
            .

     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 any distribution from the Trust, Unitholders
will be furnished with a statement setting forth the amount being distributed
from each account.

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


     Within a reasonable period of time after the end of each calendar year,
commencing with calendar year 2000, 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.



                                      B-19
<PAGE>

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

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

         (2) upon the institution of a 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 on such Securities;

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

         (5) upon the decline in price or the occurrence of any materially
     adverse 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 decrease in the Sponsor's internal rating of the Security;
     or


         (7) 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.


     Securities may also be tendered or sold in the event of a tender offer,
merger or acquisition in the manner described under "The Trust" in Part B of
this Prospectus. The Trustee may also dispose of Securities where necessary to
pay Initial Organizational Costs, Trust expenses, Deferred Sales Charge
installments 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.

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 adversely affect the interest of the
Unitholders.

     The Indenture may also be amended by the Trustee and the Sponsor without
the consent of any of the Unitholders to implement a program to reinvest cash
proceeds received by the Trust in connection with corporate actions and in
other situations, when and if the Sponsor receives a favorable response to the
no-action letter request which it intends to submit to the Division of
Investment Management at the SEC discussed above (see "Distributions" in Part B
of this Prospectus). There can be no assurance that a favorable no-action
letter response will be received.

     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.


                                      B-20
<PAGE>

     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 on the Mandatory
Termination Date. If the value of the Trust as shown by any evaluation is less
than fifty per cent (50%) of the market value of the Stocks upon completion of
the deposit of Stocks, 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.

     Unless advised to the contrary by the Sponsor, approximately 20 days prior
to the termination of the Trust the Trustee will begin to sell the Securities
held 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, after due notice of such termination, such Unitholder's pro
rata share in the Income and Capital Accounts. Moneys held upon the sale of
Securities may be held in non-interest bearing accounts created by the
Indenture until distributed and will be of benefit to the Trustee. The sale of
Securities in the Trust in the period prior to 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,
the Trust 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 willful misfeasance, bad faith, gross negligence or
willful disregard of its duties. The Sponsor will not be liable or responsible
in any way for depreciation or loss incurred by reason of the sale of any
Securities in the Trust.

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

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

negligence, bad faith or willful misconduct, nor will the Trustee be liable or

the Sponsor to act, the Trustee may act and will not be liable for any such
action taken by it in good faith. The Trustee will not be personally liable for
any taxes or other governmental charges imposed upon or in respect of the
Securities or upon the interest thereon or upon it as Trustee or upon or in
respect of the Trust which the Trustee may be required to pay under any present
or future law of the United States of America or of any other taxing authority
having jurisdiction. In addition, the Indenture contains other customary
provisions limiting the liability of the Trustee. The Trustee will be
indemnified and held harmless against any loss or liability accruing to it
without gross negligence, bad faith or willful misconduct on its part, arising
out of or in connection with its acceptance or administration of the Trust,
