PAINEWEBBER EQUITY TRUST, ABCS TRUST SERIES 6 - PROSPECTUS PART A

BRIEF DESCRIPTION OF THE TRUST

1. THE TRUST'S OBJECTIVES.

    o  The Trust seeks total return by investing in a fixed portfolio of
       stocks chosen from the PaineWebber Equity Research Department's
       "Analysts' Best Calls" lists, also called the "ABCs List."

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

    o  As of       , 2000, the first day of the Trust, PaineWebber believes
       that the Trust's portfolio of stocks have the potential for achieving
       total return during the life of the Trust because the stocks have been
       chosen from the ABCs List in the manner described below.

    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 PAINEWEBBER EQUITY RESEARCH DEPARTMENT.

    o  The PaineWebber Equity Research Department seeks to identify the best
       investment opportunities by focusing on established and emerging trends
       in economics, the stock market and individual industries and companies.

    o  The Equity Research Department analyzes opportunities in the stocks of
       individual companies by closely examining the fundamentals of the company
       and its industry. For example, the Research Department's analysts meet
       with company management, review management's strategies, evaluate the
       company's earnings potential, and examine the information gathered in the
       context of sophisticated economic and financial models.

    o  Based on the information obtained from its research, the Equity
       Research Department assigns one of four investment ratings to each stock
       that it covers: "Buy", "Attractive", "Neutral" or "Unattractive".

3. HOW ARE STOCKS CHOSEN FOR THE ABCS LIST?

    o  The ABCs List is a list of the PaineWebber Equity Research Department's
       top stock selections. The ABCs List typically contains approximately 40
       to 50 stocks.

    o  To compile the list, most of the more than 50 analysts from the Equity
       Research Department who cover over 50 different industries each choose a
       stock from their respective industry that the analyst believes is most
       likely to outperform the stock market as a whole during the following 12
       months.

    o  The stocks chosen for the ABCs List must also be rated either "Buy" or
       "Attractive" by PaineWebber's Equity Research Department. A "Buy" rating
       is assigned to the stocks PaineWebber believes will achieve a total
       return of at least 20% during that 12-month time period, assuming a flat
       market, and an "Attractive" rating is assigned to those stocks
       PaineWebber believes will achieve a total return of 10-20% within the
       same time period. Of course, there is no assurance that the stocks
       assigned such ratings will, in fact, achieve such projected total
       returns, nor that the stocks will continue to be assigned such ratings
       during the 12-month time period following the first day of the Trust.


                                      A-3
<PAGE>

4. HOW DOES PAINEWEBBER CHOOSE THE STOCKS FOR THE TRUST FROM THE ABCS LIST?

   The Trust contains    stocks chosen from the most current ABCs List. Not
   all of the stocks included in the most current ABCs List are included in
   the Trust. To be included in the Trust's portfolio, each stock had to meet
   each of the following three (3) tests on       , 2000

    o  First, the stock must appear on the most current ABCs List;

    o  Second, the stock must be issued by a company that has a market
       capitalization of at least $3 billion; and

    o  Third, the stock must be recommended by a PaineWebber Equity Research
       Department analyst who rated more than 50% of the securities that the
       analyst follows as either "Buy" or "Attractive".


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.

    o  The Trust holds a fixed portfolio of stocks chosen from the most
       current ABCs List on the first day of the Trust. Since the Trust is
       fixed, and not managed like a mutual fund, the Trust will not buy and
       sell portfolio stocks to match the most current ABCs List. Therefore,
       when new ABCs Lists are published by PaineWebber on a periodic basis,
       they may contain stocks different from those included in the most current
       ABCs List and from those held by the Trust.

    o  The Trust may, in the future, continue to buy more of the stocks held
       by the Trust when additional Units are offered to the public or for the
       Reinvestment Plan, even though those stocks may no longer be on the then
       current ABCs List at the time such purchases are made by the Trust.

     THE TRUST MAY SELL PORTFOLIO STOCKS

    o  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 meet redemptions, to sell, exchange or tender stocks under certain
       circumstances or to sell stocks in the event certain serious negative
       events occur.

    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.
       This could reduce the diversification of your investment and increase
       your share of Trust expenses.


                                      A-4
<PAGE>

     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 receive 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.


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

     o    The stocks held by the Trust may not perform as well as expected, and
          other trusts with similar investment objectives may hold stocks that
          outperform the Trust's stocks during the Trust's lifetime.

     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.


CODE OF ETHICS

     o    The Trust and the Sponsor have each adopted a code of ethics
          effective March 1, 2000 regarding personal securities transactions by
          the Sponsor's employees. The Code permits investments in securities,
          including securities that may be purchased or held by the Trust. The
          Code is designed to prevent fraud, deception and misconduct against
          the Trust and to provide for reporting of personal securities
          transactions by certain employees. The Code is on file with the
          Commission and can be reviewed and copied at the Commission's Public
          Reference Room in Washington, DC. For information on operations of
          the Public Reference room, call the Commission at (202) 942-8090. The
          Code is available on the EDGAR Database on the Commission's Internet
          site at http:/www.sec.gov. A copy may be obtained, after paying a
          duplicating fee, by electronic request at [email protected], or by
          writing the Commission's Public Reference Section, Washington, DC
          20549-0102.

----------
(1)   Unitholders pay a combination of Initial and Deferred Sales Charges.

(2)   The Initial Sales Charge of 1% of the Public Offering Price is reduced
      for purchasers of Units worth $50,000 or more. Also, certain classes of
      investors are entitled to reduced sales charges. For futher details, see
      "Public Offering of Units -- Sales Charge and Volume Discount" and "--
      Employee Discount" in Part B of this Prospectus.

(3)   The Deferred Sales Charge of $     per 100 Units will be deducted from
      the Trust's net asset value from the 3rd through 12th months of the 13
      month life of the Trust, aggregating $      per 100 Units during such
      period. If Units are redeemed prior to      , the amount of any remaining
      Deferred Sales Charge installments will be deducted from the redemption
      proceeds. See "Public Offering Price -- Sales Charge and Volume Discount"
      and "Administration of the Trust" in Part B of this Prospectus for
      further details.

(4)   The Creation and Development Fee of $ .  per 100 Units is an annual
      charge that compensates the Sponsor for the creation and development of
      the Trust. It is computed as a fixed dollar amount per Unit, determined
      on      , 2000. This fee historically had been included in the
      Total Sales Charge.

(5)   Applicable only to purchasers of Units during the initial offering period
      (approximately   weeks).

EXAMPLE

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


                                      A-6
<PAGE>

     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:

     While the Trust has a term of approximately 13 months, you may be able to
invest in future ABCs Trusts with reduced sales charges. These future sales
charges are included in the amounts provided above.

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

AVAILABILITY OF EXCHANGE OPTION

o    When this Trust portfolio is about to terminate, you may elect the
     Exchange Option and acquire units either of (1) a future ABCs Trust
     Series, if one is available, or (2) certain other PaineWebber unit trusts
     designated as "Exchange Trusts" in Prospectus Part B under the heading
     "Exchange Option."


o    Unitholders electing the Exchange Option may acquire units either of (1) a
     future ABCs Trust Series or (2) an Exchange Trust, at no Initial Sales
     Charge. Units acquired through the Exchange Option will be subject to the
     Deferred Sales Charges, if any, applicable to units of an Exchange Trust
     or to units of a future ABCs Trust Series.

o    If you notify the Sponsor by     , your Units will be redeemed and your
     proceeds from the sale of the Trust's securities will be reinvested on ,
     2000 in units either of (1) of a future ABCs Trust Series or (2) an
     Exchange Trust.

o    If you decide not to elect the Exchange Option, you will receive a cash
     distribution after this Trust portfolio terminates.

o    For a discussion of the tax effects of electing the Exchange Option, see
     "Exchange Option" in this Prospectus Part B. Unitholders are encouraged to
     consult with their own tax advisors as to the consequences to them of
     electing the Exchange Option.


IS THIS TRUST APPROPRIATE FOR YOU?

     Yes, if you are seeking total return over the life of the Trust by
investing in common stocks issued by companies which PaineWebber selected for
their growth and/or income potential. You can benefit from a professionally
selected portfolio whose risk is reduced by investing in stocks of several
different issuers from various industries.

     No, if you want a managed 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 stocks 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
     dividend0 in the Income Account. (See "Summary of Certain Trust
     Features--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, ten (10)
     monthly Deferred Sales Charges of $ per 100 Units (totalling $       per
     100 Units) will be deducted from the Trust's net asset value during the
     third (3rd) through twelfth (12th) months of the Trust's thirteen (13)
     month 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    The Creation and Development Fee of $ . per 100 Units is an annual charge
     that compensates the Sponsor for the creation and development of the
     Trust. It is computed as a fixed dollar amount per unit, determined on
                  , 2000 and and is deducted from the Trust's net assets at the
     same time as the Initial Organizational Costs of the Trust are deducted
     (see footnote 6 above). This fee historically had been included in the
     Total Sales Charge.

8    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 securities 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 securities 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 of $0. 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).

                        REPORT OF INDEPENDENT AUDITORS



        THE UNITHOLDERS, SPONSOR AND TRUSTEE
        THE PAINEWEBBER EQUITY TRUST, ABCs TRUST SERIES 6

        We have audited the accompanying Statement of Net Assets of The
        PaineWebber Equity Trust, ABCs Trust Series 6, including the Schedule
        of Investments, as of      , 2000. This financial statement is the
        responsibility of the Trustee. Our responsibility is to express an
        opinion on this financial statement based on our audit.

        We conducted our audit in accordance with auditing standards generally
        accepted in the United States. Those standards require that we plan and
        perform the audit to obtain reasonable assurance about whether the
        financial statement is free of material misstatement. An audit includes
        examining, on a test basis, evidence supporting the amounts and
        disclosures in the financial statement. Our procedures included
        confirmation with Investors Bank & Trust Company, Trustee, of an
        irrevocable letter of credit deposited for the purchase of securities,
        as shown in the financial statement as of      , 2000. An audit also
        includes assessing the accounting principles used and significant
        estimates made by the Trustee, as well as evaluating the overall
        financial statement presentation. We believe that our audit provides a
        reasonable basis for our opinion.

        In our opinion, the financial statement referred to above presents
        fairly, in all material respects, the financial position of The
        PaineWebber Equity Trust, ABCs Trust Series 6 at      , 2000, in
        conformity with accounting principles generally accepted in the United
        States.

</TABLE>

----------
     (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 Valuation 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, Deferred Sales Charges of $     per 100 Units,
payable in ten equal monthly installments on the tenth (10th) day of each month
from the third (3rd) through twelfth (12th) months of the Trust for an
aggregate amount of $      per 100 Units, will be deducted. Amounts will be
credited to an account maintained by the Trustee from which the Deferred Sales
Charge obligation of the Unitholders to the Sponsor will be met. If Units are
sold, redeemed or exchanged prior to        , the remaining portion of the
Deferred Sales Charge applicable to such redeemed Units will be deducted from
the proceeds and will be credited to the account on such sale, exchange or
redemption date. 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
maximum Deferred Sales Charge would be $         .

                     THE COMPOSITION OF THE TRUST PORTFOLIO


     PaineWebber observes that the challenge for many investors today is to
build a portfolio that offers the potential for solid performance from the
thousands of issues currently trading in the market. PaineWebber has
historically maintained a commitment to providing its clients with superior,
performance-oriented equity research.

     Analysts' Best Calls ("ABCs") is a compilation of PaineWebber's research
analysts' top stock selections. Most of the more than 50 PaineWebber senior
analysts who cover over 50 different industries each select a stock from their
respective sectors based on their assessment of the likelihood that the stock
will outperform the market over the next 12 months. The ABC is the stock the
analyst believes has the highest total return potential in its universe and on
which the analyst has the highest level of conviction, and must be rated either
"Buy" or "Attractive" by PaineWebber. ABCs are drawn from the entire range of
industries and companies covered by the PaineWebber Equity Research Department
(the "Equity Research Department"). Historically, the ABCs list has comprised
approximately 40 to 50 stocks. The stocks included in the Trust (the "Stocks"
or the "Securities") were chosen from the entire universe of the stocks on the
ABCs list. Investors should note that because the Stocks held by the Trust were
subject to several selection screens described below, the Trust may not hold
the entire ABCs list.

     The Stocks included in the Trust were chosen in the following manner:
first, all Stocks had to be ABCs as of the day prior to the Initial Date of
Deposit. Second, the issuer of each Stock had to have a minimum market
capitalization of $3 billion. Third, only Stocks chosen by PaineWebber research
analysts who rated more than 50% of their followed stocks either "Buy" or
"Attractive", were permitted to be included in the Trust. All Stocks meeting
these three criteria were included as Stocks in the Trust's Portfolio shown
under the heading "Schedule of Investments" in Part A of this Prospectus.

     All the Stocks in the Trust Portfolio are common stocks issued by
companies that may 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.

                   THE PAINEWEBBER EQUITY RESEARCH DEPARTMENT

     The Equity Research Department seeks to identify today's best investment
opportunities based on established and emerging economic, market, industry and
company trends. Using a fundamental approach, PaineWebber's research
professionals visit with the company management teams and evaluate their
strategies in terms of the probable impact on corporate earnings. At
PaineWebber, the process involves a constant and dynamic dialogue among
strategists, economists and analysts; using leading-edge technology, they look
at information from the top down and the bottom up, challenging each others'
assumptions and continuously sharpening their focus on both major issues and
supporting details. After visiting their companies, building detailed financial
models, evaluating near-and-longer term prospects for each company and its
competitors, establishing valuation frameworks for each stock, and factoring-in
the work of PaineWebber's strategists and economists, the analyst assigns an
investment rating to the stock.

     PaineWebber analysts assign one of four investment ratings to each stock
under research coverage: "Buy", "Attractive", "Neutral" or "Unattractive". Each
rating assumes a 12-month time horizon and is


                                      B-1
<PAGE>

based on a stock's total return potential (stock price appreciation plus
dividend) relative to the market. A "Buy" rating is assigned to those stocks
PaineWebber believes will achieve total return of at least 20% in a flat
market. A stock rated "Attractive" is one which PaineWebber believes will offer
total return of 10-20% in the coming 12-month period. The "Neutral" rating is
assigned to those stocks which are selling within 10% of the PaineWebber
analysts' estimated price targets one year out and whose stock prices are not
expected to change materially in price during the next 12 months. The
"Unattractive" rating is assigned to those stocks which PaineWebber believes
has at least ten percentage points more downside risk than the current dividend
yield, assuming a flat market environment.


     The Research Department has been long recognized as one of the leaders on
Wall Street. PaineWebber has been named among the top 10 investment firms in
Institutional Investor's "All America Research Team," in each of its 28 annual
surveys. Institutional Investor bases this ranking on the opinions of directors
of research, chief investment officers, portfolio managers and analysts of
major money management institutions. Additionally, The Wall Street Journal
reported that PaineWebber's "Performance Portfolio," which is submitted by the
Research Department to Zacks Investment Research, ranked eleventh among the
submitted lists of 15 major firms for the five-year period ended June 30,
2000, achieving a return of 153.6%. For the one-year performance period ended
June 30, 2000, PaineWebber's Performance Portfolio was ranked number 14 out
of 15 firms, achieving a return of -3.2%. The Wall Street Journal arrives at
this ranking by comparing the estimated performance of stocks on the
recommended lists submitted by 15 major brokerage firms. The performance
figures are computed using a variety of data, including stock price changes,
dividends and hypothetical trading commissions of 1%. Each brokerage firm
constructs its recommended list using the criteria it deems important;
PaineWebber's Performance Portfolio consists of a select list of stocks rated
"Buy" or "Attractive" by PaineWebber's investment research analysts.
Additionally, PaineWebber's Performance Portfolio is selected by PaineWebber
Research Department management and the stocks included in the Portfolio have no
minimum market capitalization requirements. In contrast, the stocks included in
the ABCs Series Trust are chosen by individual Equity Research Analysts and are
subject to a minimum market capitalization requirement discussed below. There
is no assurance that PaineWebber will be successful in stock selection during
the term of this Trust or will continue to be highly ranked among investment
firms for stock selection. The stocks on the ABCs list may not be, during the
term of this Trust, the same stocks as those contained in the Performance
Portfolio.


                       SUMMARY OF CERTAIN TRUST FEATURES

     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 this Prospectus Part B). The
Trust, when acquiring such Additional Securities, may purchase Stocks
notwithstanding that, at the time of such purchase, such Stocks are no longer
included in the most current ABCs list. 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 additional deposits of Securities purchased
by the Trustee with cash or cash equivalents pursuant to instructions to
purchase such Securities. (See "The Trust" and "Risk Factors and Special
Considerations" in this Prospectus Part B.)

     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 $     per 100 Units over the
third (3rd) through twelfth (12th) months of the thirteen (13) month life of
the Trust. For example, on a $1,000 investment, $    is invested in the Trust
and a $10.00 Initial Sales Charge is collected. In addition, a Deferred Sales
Charge of $    per 100 Units will be deducted from the Trust's net asset value
on the tenth (10th) day of each month from months three (3) through twelve (12)
of the Trust's life for a total of $    . This deferred method of payment keeps
more of the investor's money


                                      B-2
<PAGE>

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
Initial Sales Charge is reduced on a graduated scale for volume purchasers and
is reduced for certain other purchasers. 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 any date subsequent to
the Initial Date of Deposit, will vary from the Public Offering Price set forth
on page A-9 of this Prospectus. Units redeemed or repurchased prior to the
accrual of the final Deferred Sales Charge installment will have any amount of
any remaining installments deducted from the redemption or repurchase proceeds
or deducted in calculating an in-kind redemption. (See "Public Offering of
Units" in this Prospectus Part B). In addition, during the initial public
offering period, the Public Offering Price per 100 Units 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
this Prospectus Part B.


     Distributions. The Stocks in the Trust were chosen for their total return
potential, not for their income potential. The Trustee will make distributions
on the Distribution Dates. (See "Distributions" and "Administration of the
Trust" in this Prospectus Part B.) Unitholders may elect to have their Income
and Capital Account distributions automatically reinvested into additional
Units of the Trust (see "Reinvestment Plan" in this Prospectus Part B). 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 this
Prospectus Part B). Unless advised to the contrary by the Sponsor, the Trustee
will begin to sell the Securities held in the Trust approximately fifteen 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 thirteen (13) months after the Initial Date of
Deposit regardless of market conditions at the time. (See "Termination of the
Trust" and "Federal Income Taxes" in this Prospectus Part B.)


     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 this
Prospectus Part B.) 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 this Prospectus
Part B.)

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 total return
through an investment in equity securities selected from PaineWebber's ABCs
list. 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 this Prospectus Part B.
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 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 this Prospectus Part
B).

     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


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


                                      B-4
<PAGE>

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 this
Prospectus Part B.)

     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 "ADMINISTRATION OF THE TRUST--PORTFOLIO SUPERVISION"
IN THIS PROSPECTUS PART B). 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 selected through this process. This may be the case even though the
Securities may no longer be included in the current ABCs list or 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


                                      B-5
<PAGE>

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.

     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. 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.

     Any distributions of income to Unitholders will generally depend upon the
declaration of dividends by the issuers of Securities and the declaration of
dividends depends upon several factors, including the financial condition of
the issuers and general economic conditions. 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.


                                      B-6
<PAGE>

     Investors should note that the Trust's objective may not be realized
because the Securities held in the Trust's portfolio may not perform as well as
expected, and other investment vehicles with similar investment objectives may
hold stocks that outperform the Trust's stocks during the Trust's lifetime.

     The Sponsor's buying and selling of the Securities, especially during the
initial offering of Units of the Trust, or to satisfy redemptions of Units, to
reimburse the Sponsor for the Initial Organizational Costs or to pay the
accrued Deferred Sales Charges and Creation and Development Fee to the Sponsor,
may impact upon the value of the underlying Securities and the Units. During
the initial public offering period the Sponsor may also purchase large blocks
of the Securities in connection with the offering of other investment funds
holding substantially the same portfolio of Securities as the Trust. The
Sponsor's acquisition of certain of the Securities in open market purchases may
have the unintended result of increasing the market price for such Securities
during the period that the Sponsor is acquiring Securities for the Trust. The
publication of the list of the Securities selected for the Trust may also cause
increased buying activity in certain of the Securities comprising the Trust
portfolio. After such announcement, investment advisory and brokerage clients
of the Sponsor and its affiliates may purchase individual Securities appearing
on the list during the course of the initial offering period. Such buying
activity in the stock of these companies prior to the purchase of the
Securities by the Trust may cause the Trust to purchase stocks at a higher
price than those buyers who effect purchases prior to purchases by the Trust
and may also increase the amount of the profit realized by the Sponsor on the
purchase of the Securities for deposit into the Trust.

     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.

     Investors should note that the Trust has adopted an internal policy which
prohibits the ownership of any issue of Securities by all series of the ABCs
Trust combined beyond 9.9% of the then-current outstanding common stock of such
issuer. The Sponsor is authorized to immediately discontinue the offering of
any additional Units of any ABCs Trust Series, including those to be created
for Reinvestment Plan purposes, until such time as all ABCs Trust series, in
the aggregate, hold less than 9.9% of the then-current outstanding common stock
of such issuer.

     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


                                      B-7
<PAGE>

deposited (in which case the original proportionate relationship shall be
adjusted) or, if not so reinvested, distributed to Unitholders of record on the
last day of the month in which the failure occurred. The distribution will be
made fifteen 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 only under certain limited circumstances. (See the
discussion below relating to disposition of Stocks which may be the subject of
a tender offer, merger or reorganization and also the discussion under the
caption "Administration of the Trust--Portfolio Supervision" in this Prospectus
Part B.)

     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.

     Certain of the 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 based on the terms of its
offer. Payment generally takes the form of cash, securities (typically bonds or
notes), or cash and securities. The Indenture contains provisions requiring the
Trustee to follow certain procedures regarding mergers, acquisitions, tender
offers and other corporate actions. Under certain circumstances, the Trustee,
at the direction of the Sponsor, may hold or sell any stock or securities
received in connection with such corporate actions (see "Administration of the
Trust--Portfolio Supervision" in this Prospectus Part B).


                                      B-8
<PAGE>

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


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).

     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


                                      B-9
<PAGE>

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.

     Corporate Dividends-Received Deduction. Corporate holders of Units may be
eligible for the dividends-received deduction with respect to distributions
treated as dividends, subject to the limitations provided in 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 this Prospectus Part B.) The Public Offering Price on any date
subsequent to the Initial Date of Deposit will vary from the Public Offering
Price calculated on the business day prior to the Initial Date of Deposit (as
set forth on page A-9 hereof) 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 in "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 this Prospectus Part B for a
description of the method by which the Trustee will sell such Securities.

     Sales Charge and Volume Discount. Units will be charged a Total Sales
Charge of approximately 2.75% per 100 Units which is a combination of the
Initial and Deferred Sales Charges. The Initial Sales Charge will be $10.00 per
100 Units on the Initial Date of Deposit (1.00% of the Public Offering Price).
Commencing in the third (3rd) month and continuing through the twelfth (12th)
month of the Trust's thirteen (13) month life, the Deferred Sales Charge per
100 Units will be $    , approximately 1.75% of the Public Offering Price.
Because the Deferred Sales Charge per 100 Units is $     regardless of the
price paid for Units, the Total Sales Charge expressed as a percentage of the
Public Offering Price will vary with the price you pay to purchase Units. So,
for example, if an investor bought 100 Units for $1,000 (including the Initial
Sales Charge of $10.00 and held the Units until the Trust terminates, such
investor would pay a Total Sales Charge of $27.50 or 2.75% of the acquisition
price for such Units. If, however, an


                                      B-10
<PAGE>

investor bought 100 Units for $900 (including the Initial Sales Charge of
$9.00), such investor would pay a Total Sales Charge of $     or    % 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 $     or    % of the acquisition price for such Units.

     The Deferred Sales Charge is a charge of $      per 100 Units and is
accrued in ten (10) monthly installments during the first twelve (12) months of
the life of the Trust ($      annual total) commencing in the third (3rd) month
of the Trust. UNITS REDEEMED OR REPURCHASED PRIOR TO THE ACCRUAL OF THE FINAL
DEFERRED SALES CHARGES INSTALLMENT WILL HAVE THE AMOUNT OF ANY INSTALLMENTS
REMAINING DEDUCTED FROM THE REDEMPTION OR REPURCHASE 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.

     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. Investors will be at risk for market price
fluctuations in the Securities from the several installment accrual dates to
the date of actual sales of Securities to satisfy this liability.

     A discount in the Initial 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 Initial 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.

     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 Total Sales Charge.


                                      B-11
<PAGE>

     Eligible Accounts. Investors holding Units of this Trust in certain
eligible accounts offered by the Sponsor will pay no sales charges.

     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 80% of the Total
Sales Charge (2.75%) per Unit, 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 ABCs Trust Series 6 sold in the
primary market from     , 2000 through     , 2000 (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
the ABCs Trust Series 6, 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 this Prospectus Part B. 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 that 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


                                      B-12
<PAGE>

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.

     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 this Prospectus Part B).

     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 this Prospectus
Part B. The cost of Stock to the Sponsor includes the amount paid by the
Sponsor for brokerage commissions.

     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 to the extent permitted by
federal law 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.

     The Sponsor will receive an annual Creation and Development Fee of $
per 100 Units. This annual fee, which has historically been included in the
Total Sales Charge, compensates the Sponsor for the Creation and Development of
the Trust's objective, policies, portfolio composition and size, selection of
service providers and information services. No portion of the Creation and
Development Fee is applied to the payment of distribution expenses or as
compensation for sales efforts.


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. 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 this Prospectus Part
B.) Unitholders who redeem prior to the accrual of the final Deferred Sales
Charges installment will 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.


                                      B-13
<PAGE>

     A redemption request is deemed received on the business day (see
"Valuation" in this Prospectus Part B 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 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 this Prospectus Part B.)
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 this Prospectus Part B. 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, as amended.

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

     The Trustee may, in its discretion, and will, when so directed by the
Sponsor, suspend the right of redemption, or postpone the date of payment of
the Redemption Value, for more than seven calendar days following the day of
tender for any period during which the New York Stock Exchange, Inc. is closed
other than for weekend and holiday closings; or for any period during which the
SEC 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 SEC 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


                                      B-14
<PAGE>

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 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 last reported 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 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" 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.


                                      B-15
<PAGE>

EXPENSES OF THE TRUST

     The Sponsor will receive a fee, which is earned for portfolio supervisory,
bookkeeping and administrative services, 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 and expenses of
providing such services for the Trust, but at no time will the total amount it
receives for such services rendered to all series of the PaineWebber Equity
Trust in any calendar year exceed the aggregate amounts attributable to all
such series during such calendar year.

     For its services as Trustee and Evaluator, the Trustee will be paid in
monthly installments, annually $     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 $     per Unit, which
include, but are not limited to certain mailing, printing, and audit expenses.
These expenses, including 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.

     The Sponsor will also receive an annual Creation and Development Fee of
$.    per 100 Units. This fee, which historically has been included in the
Total Sales Charge, compensates the Sponsor for the creation and development of
the Trust's objectives, policies, portfolio composition and size, selection of
service providers and information services. No portion of the Creation and
Development Fee is applied to the payment of distribution expenses or as
compensation for sales efforts.

     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 this Prospectus Part B): (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 SEC, 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
$0.50 per Unit, unless the Trustee has been advised that such expenses are
permitted by the SEC to be deducted from the Trust. 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


                                      B-16
<PAGE>

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 this
Prospectus Part B.


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.


DISTRIBUTIONS

     The Trustee will distribute net dividends and interest, if any, from the
Income Account on the quarterly Income Account Distribution Dates to
Unitholders of record on the preceding Record Date. Distributions from the
Capital Account will be made on the Capital Account Distribution Date to
Unitholders of record on the preceding Record Date. Distributions of less than
$.05 per Unit need not be made from the Capital Account on any Distribution
Date. See "Essential Information" 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. (See
"Reinvestment Plan" in this Prospectus Part B).

     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 this Prospectus Part B.)


REINVESTMENT PLAN

     Income Account and Capital Account distributions on Units may be
automatically reinvested in additional Units of the Trust without any Initial
Sales Charge by participating in the Trust's Reinvestment Plan (the
"Reinvestment Plan"). 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


                                      B-17
<PAGE>

made so as to maintain the percentage relationships of shares of Stocks, except
as discussed under "The Trust" in this Prospectus Part B. If a Unitholder
elects to participate in the Reinvestment Plan, in addition to the reinvestment
Units he will receive, the Unitholder will also be credited additional Units
with a dollar value at the time of reinvestment sufficient to offset the amount
of any remaining deferred sales charge to be collected on such reinvestment
Units. The dollar value of these additional Units (as with all Units) will
fluctuate over time. 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 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 (except that in no event may
the Reinvestment Plan be amended or modified in such a way as to require
payment of deferred sales charges on reinvestment Units unless the Unitholder
will receive additional Units or cash to offset such deferred sales charges) at
any time without prior notice. Unitholders receiving Units as a result of their
participation in the Reinvestment Plan will be taxed with respect to such Units
in the manner described in "Federal Income Taxes" earlier in this Prospectus
Part B.


EXCHANGE OPTION


     Unitholders, in lieu of redeeming their Units or receiving liquidation
proceeds upon termination of this Trust series, may elect, by contacting the
Sponsor no later than 12 noon EST on (the "Exchange Notification Date"), to
exchange their Units of this Trust series either for units of (1) a future
series of the ABCs Trust or (2) Units of certain other Unit trusts designated by
PaineWebber as "Exchange Trusts" on the Special Redemption Date at no Initial
Sales Charge. Units acquired by means of the Exchange Option will be subject to
the Deferred Sales Charges, if any, applicable to units of an Exchange Trust or
to units of a future series of the ABCs Trust. No election to exchange may be
made prior to 40 days before the Exchange Notification Date and any exchange
election will be revocable at any time prior to 12 noon EST on the Exchange
Notification Date. It is expected that the terms of a future ABCs Trust series
will be substantially the same as those of this Trust series. The Sponsor
reserves the right not to offer future series of the ABCs Trust and there is no
guarantee that a future series will be available on the Special Redemption Date.

     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, for example, would not be
suitable for tax-deferred investment plans such as Individual Retirement
Accounts. A Unitholder electing to use the Exchange Option in connection with
acquiring units of an Exchange Trust subject to a deferred sales charge
("Deferred Sales Charge Units") will be permitted to acquire Deferred Sales


                                      B-18
<PAGE>

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, or a secondary market maintained by the Sponsor, for 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 Exchange Trusts, there is no obligation on its
part to maintain such a market. Therefore, there is no assurance that a market
for units will in fact exist on the Special Redemption Date 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 a Unitholder's Units will be accomplished by the in-kind
redemption of such Units, followed by the sale of the underlying Securities by
the Trustee acting as the distribution agent (the "Distribution Agent") on
behalf of participating Unitholders, and the reinvestment of the sale proceeds
(net of brokerage fees, governmental charges and other sale expenses) in units
either of (1) a future ABCs Trust series or (2) an Exchange Trust, at their
then-current net asset value.

     Certain of the underlying Securities held in the portfolio of an existing
ABCs Trust Series may also be included in the portfolio of a future ABCs Trust
Series made available to Unitholders electing to exchange their Units on a
Special Redemption Date. For example, certain stocks in the portfolio of ABCs
Trust Series 3 also appear in the portfolio of ABCs Trust Series 6. In such
cases, a direct sale of these stocks from one ABCs Trust Series to a future
ABCs Trust Series is now permitted pursuant to an SEC exemptive order discussed
below. These direct sales will be effected at the stocks' closing sales prices
on the exchanges where they are principally traded, free of any brokerage
charges. The remaining securities in the existing ABCs Trust Series which will
not be held in the portfolio of the future ABCs Trust Series will be sold, in
the manner discussed below in the next paragraph, and the proceeds of such sale
will be used to buy the other securities required for deposit into the
portfolio of the future ABCs Trust Series.

     The Sponsor intends to direct the sale of the Securities by the
Distribution Agent, as quickly as practicable, subject to the concerns that the
concentrated sale of large volumes of securities may affect market prices in a
manner adverse to the interest of investors. Accordingly, the Sponsor may, in
its sole discretion, undertake to cause a more gradual sale of such Securities
to help mitigate any negative market price consequences caused by this large
volume of securities trades. In order to minimize potential losses caused by
market movement during this period, program trades may be utilized in
connection with the sales of the Distributed Securities, which might increase
brokerage commissions payable by investors. There can be no assurance, however,
that any trading procedures will be successful or might not result in less
advantageous prices. Sales of Securities pursuant to program trades will be
made at such Securities' closing prices on the exchange or system where they
are principally traded.

     Unitholders electing the Exchange Option may realize taxable capital gains
but will not be entitled to a deduction for certain capital losses realized.
Moreover, because of the exchange procedures described above, Unitholders
should be aware that they will not receive a cash distribution to pay any taxes
owed. Unitholders are encouraged to consult with their own tax advisors as to
the consequences to them of electing the Exchange Option.

     The Sponsor reserves the right to modify, suspend or terminate this
Exchange Option at any time with 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.


                                      B-19
<PAGE>

     To exercise the Exchange Option, a Unitholder should notify the Sponsor by
no later than 12 noon EST on the Exchange Notification Date that such
Unitholder wishes to exercise the Exchange Option and to use the proceeds from
the sale of underlying Securities in respect of his in-kind redemption of Units
of this Trust to purchase units of a future ABCs Trust series or an Exchange
Trust from the Sponsor. If units of a future ABCs Trust series or an 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 will be
provided with a current prospectus or prospectuses relating to such future ABCs
Trust series or Exchange Trust.

     Unitholders who do not exercise the Exchange Option, or otherwise sell or
redeem their Units, will continue to hold their Units until the termination of
the Trust; however, depending upon the extent of participation in the Exchange
Option, the aggregate size of the Trust may be sharply reduced, resulting in a
significant increase in per Unit expenses.

     The Division of Investment Management of the SEC is of the view that the
Exchange Option constitutes an "exchange offer", for the purposes of Section
11(c) of the Investment Company Act of 1940, and would therefore be prohibited
absent an exemptive order. The Sponsor has received exemptive orders under
Section 11(c) which the Sponsor believes permit the offering of this Exchange
Option, but no assurance can be given that the SEC will concur with the
Sponsor's position and additional regulatory approvals may be required. In
addition, Section 17(a) of the Investment Company Act prohibits one trust
series from selling securities to another trust series when such trust series
are under the control of a common sponsor. With regard to the Exchange Option,
Section 17(a) would prohibit the direct sale of securities from one ABCs Trust
Series to another on the books of the Trustee without an exemptive order. The
Sponsor has received an exemptive order from the SEC which, subject to certain
exceptions, permits the direct sale of securities from one ABCs Trust Series to
another on the books of the Trustee.



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 and
interest income, if any, 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 this Prospectus Part B.

     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 of the Trust" in this Prospectus
Part B.) 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 this Prospectus Part B.) 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


                                      B-20
<PAGE>

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 the Special Redemption
Date.

     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 calendar year 2000,
the Trustee will furnish each person who was a Unitholder at any time during
such periods 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 such periods and the
Securities held at the end of such periods; (3) the Trust Fund Evaluation per
Unit, based upon a computation thereof on the last business day of such
period); and (4) amounts distributed to Unitholders during such periods.

     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.


                                      B-21
<PAGE>

     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 this
Prospectus Part B.


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
alter any provision as may be required by the SEC 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 this
Prospectus Part B). 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.

     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 forty per cent (40%) 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 15 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,


                                      B-22
<PAGE>

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.

TRUSTEE

     The Trustee is Investors Bank & Trust Company, a Massachusetts trust
company with its principal office at Hancock Towers, 200 Clarendon Street,
Boston, Massachusetts 02116, toll-free number 800-356-2754, which is subject to
supervision by the Massachusetts Commissioner of Banks, the Federal Deposit
Insurance Corporation and the Board of Governors of the Federal Reserve System.

     The Indenture provides that the Trustee will not be liable for any action
taken in good faith in reliance on properly executed documents or the
disposition of moneys, Securities or Certificates or in respect of any
valuation which it is required to make, except by reason of its own gross
negligence, bad faith or willful misconduct, nor will the Trustee be liable or
responsible in any way for depreciation or loss incurred by reason of the sale
by the Trustee of any Securities in the Trust. In the event of the failure of
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,
including the costs and expenses (including counsel fees) of defending itself
against any claim of liability.
