EQUITY OPPORTUNITY TRUST, MID-CAP SERIES 2 - PROSPECTUS PART A

BRIEF DESCRIPTION OF THE TRUST

1. OBJECTIVES.

o The Equity Opportunity Trust, Mid-Cap Series 2 ("Trust") seeks capital
appreciation by investing for approximately one year in a fixed portfolio
of 10 stocks ("Portfolio") chosen by the Sponsor from the 400 stocks in
the S&P Mid-Cap 400 Index (referred to herein as the "Index").*

o The 10 stocks included in the Portfolio were chosen by the Sponsor on
January 21, 2005, because at that time they met the criteria in the
screening process described below, and we believe have capital
appreciation potential.

o You can invest in the Portfolio by purchasing units of the Trust
("Units"). Each Unit represents an equal share of the Portfolio stocks
and is entitled to an equal share of dividend income generated by such
stocks after deducting Trust expenses.

2. THE MID-CAP SERIES INVESTMENT STRATEGY.

The strategy of the Trust is "Growth" oriented, meaning that it
emphasizes the future earnings potential of a company's equity
securities. It focuses on stocks whose future expected long term earnings
growth rate exceeds the multiple at which its shares are currently
trading in the market relative to earnings per share. This is measured by
use of the "PEG" ratio, which is defined as a stock's price to earnings
ratio ("P/E") divided by its forecast long-term earnings growth rate
("G"). The forecast used is the median consensus forecast as measured by
an independent market data vendor.

After calculating the PEG ratio for all 400 stocks in the Index, the
Sponsor selects stocks whose PEG ratio is greater than zero to ensure
that the portfolio will hold only those stocks which have positive
forecast earnings growth, but less than 1.00, to avoid choosing stocks
which are trading at multiples of earnings which are equal to or exceed
their forecast long term earnings growth rate. The remaining stocks are
then ranked by market capitalization for liquidity reasons, and the
stocks with the top ten (10) market capitalizations are selected for the
Trust. The strategy consists of the Trust holding a fixed portfolio of
approximately equal amounts of these 10 stocks from the S&P MidCap 400
Index, selected on the second Business Day** prior to the date of this
Prospectus. We believe these stocks may be well priced relative to their
ability to grow future earnings and their capital appreciation potential.

o After approximately one year, investors wishing to continue with this
strategy may elect to liquidate their investment in the Trust and invest
the proceeds in a new Mid-Cap Trust, if one is then available. Investors
not wishing to continue with this strategy will receive their share of
the liquidation proceeds of the Portfolio stocks ("Liquidation Proceeds")
upon termination of the

Trust, approximately one month later. The stocks in the portfolio of the
new Mid-Cap Trust will be the 10 stocks of the Index which meet the
selection criteria on the date they are chosen for the new Mid-Cap Trust,
which generally will be two Business Days prior to the date of the
prospectus offering units of such new trust.

3. FOLLOWING THE MID-CAP SERIES INVESTMENT STRATEGY OVER A PERIOD OF TIME.

o Investors can sell their Trust Units at any time, or receive their share
of the Liquidation Proceeds once this Mid-Cap Trust is terminated. The
Sponsor believes, however, that to obtain the benefits of the Investment
Strategy investors should reinvest or "rollover" into the next available
series of the Mid-Cap Trust for a period of at least 3 to 5 years.

o While there is no guarantee that future trusts will be available for
purchase, UBS Financial Services Inc. anticipates several Mid-Cap Series
offerings in 2006. Unitholders of this Trust (Mid-Cap Series 2) may elect
the Rollover Option and roll into the Mid-Cap Series expected to be
offered on February 23, 2006, if available, at a reduced sales charge
(see "Public Offering of Units -- Rollover Option" in Part B of this
Prospectus).

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

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. SPECIAL RISKS OF INVESTING IN THE TRUST

The 10 common stocks held by the Trust are considered mid-cap stocks
because they generally have mid-size market capitalizations that are greater
than those of small-cap stocks but lower than those of large-cap stocks. Market
capitalization is defined as the total market value of a company's equity
securities and is calculated by multiplying the total number of shares
outstanding by the current share price.

There is no absolute cut-off point for classifying a stock by market
capitalization; the categories are relative to one another and fluctuate over
time with overall market conditions. However, as a guideline, these stocks tend
to have a market capitalization in the range of $1 billion to $4 billion. As a
result, mid-cap stocks may experience greater share price volatility and less
liquidity than large-cap stocks.

The 10 Portfolio stocks may experience changes in their dividend rates or share
prices which may reduce their total return potential during the life of the
Trust.

Portfolio performance can be expected to vary from the performance of the Index
or the historical performance of the Investment Strategy.

2. RISKS OF INVESTING IN THE TRUST

Certain risks are involved with an investment in a unit trust that 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 from the Portfolio to take advantage of market
fluctuations.

A-4

o The Trust holds a fixed Portfolio of stocks chosen from the Index on the
second Business Day prior to the date of this Prospectus. For this
reason, the Trust's "yearly" performance will not be measured from
January 1st through December 31st, as are the performance data for the
indexes and the constructed Portfolio below on page A-10.

o Since the Trust is fixed and not managed like a mutual fund, the Trust
will not buy and sell Portfolio stocks to match the ten Index stocks
which currently meet the criteria in the screening process described
above. Additionally, because the stocks in the Index may change, the
stocks held in the Portfolio may no longer be included in the Index.

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 the ten
Index stocks which currently meet the criteria in the screening process
described above or may no longer be in the Index at the time such
purchases are made by the Trust.

o The Portfolio does not reflect any investment recommendations and one or
more of the stocks in the Portfolio, may, from time to time, be subject
to the Sponsor's "reduce" recommendation.

THE TRUST MAY SELL PORTFOLIO STOCKS

o The Portfolio may not remain constant during the life of the Trust. The
Trustee may be required to sell Portfolio stocks to pay expenses and/or
to meet redemptions. Stocks will be sold in a way to maintain, as closely
as possible, the proportionate relationship among the stocks. Certain
Portfolio stocks may also be sold, exchanged or tendered under certain
circumstances or in the event certain serious negative events occur with
respect to those stocks.

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

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 or political influences
that affect the global or United States economy.

o Assuming no changes occur in the prices of the Portfolio 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 and because of the deduction of various charges, fees and
expenses.

o The stocks in the Trust's Portfolio are generally liquid, although
mid-cap stocks are generally less liquid than large-cap stocks (such as
those in the S&P 500 Index (Registered Trademark) *) and 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.

----------
* "S&P 500 Index (Registered Trademark) " is a trademark of the McGraw-Hill
Companies Inc., which is not affiliated with the Sponsor, has not
participated in the creation of the Trust or the Investment Strategy, and
has not reviewed or approved any information in this Prospectus.

A-5

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.

3. GENERAL RISKS OF INVESTING IN STOCKS

INVESTING ALWAYS INVOLVES RISKS. The risks described below are the most
significant risks associated with investing in the Portfolio 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 or political
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.

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

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:

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

CREATION AND DEVELOPMENT FEE

The Creation and Development Fee is a charge of 0.25% collected at the end of
the Initial Offering Period. It compensates the Sponsor for the creation and
development of the Trust and is computed based on the Trust's average daily net
asset value through the date of collection. No portion of the Creation and
Development Fee is applied to the payment of costs associated with marketing
and distributing the Trust. The Creation and Development Fee may be more or
less than 0.25% of your initial investment depending on the average net asset
value through the date of collection. In no event, however, will Unitholders
pay more than 0.30% of their initial investment. The following table shows how
the Creation and Development Fee as a percentage of the initial investment may
vary as average net asset value changes.

MARKETING AND DISTRIBUTION FEES

Unitholders will pay an Initial Sales Charge of 1%, plus six (6) monthly
Deferred Sales Charges of $2.50 per 1,000 Units (totaling $15.00 per 1,000
Units), which will be deducted from the Trust's net assets from July, 2005
through December, 2005. The Initial and Deferred Sales Charges cover the costs
associated with marketing and distributing the Trust. See "Public Offering of
Units" in Part B of this Prospectus for further details.

5. BRIEF DESCRIPTION OF THE TRUST'S INVESTMENT PORTFOLIO

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

PERCENTAGE OF
PRIMARY INDUSTRY SOURCE AGGREGATE NET ASSET VALUE OF THE TRUST
--------------------------------------------------- ---------------------------------------

Building -- Residential/Commercial ......... 29.98%
Financial Institutions/Banks ............... 10.06%
Insurance -- Financial Guarantees .......... 9.96%
Insurance -- Health Care ................... 10.06%
Insurance -- Multi-Line .................... 10.01%
Insurance -- Property/Casualty ............. 10.01%
Reinsurance ................................ 9.98%
Telecommunications ......................... 9.94%

6. RISKS SPECIFIC TO THE RESIDENTIAL BUILDING INDUSTRY.

Approximately 30% of the Trust's Portfolio consists of stocks issued by
companies in the residential and commercial building industry and is therefore
considered to be "concentrated" in this industry. The Trust is therefore more
susceptible to risks and uncertainties experienced by companies in this
industry than if it were more broadly diversified, and adverse developments in
this industry may significantly affect the value of your Units. Profits made by
companies engaged in the residential and commercial building industry are
affected by many factors, including local, regional and national economic
conditions, the demand for homes, domestic and international political events,
uncertainties created by terrorist attacks, the effects of governmental
regulation, the competitive environment in which the companies operate,
fluctuations in interest rates, changes in home prices, the availability and
cost of land for future growth, the availability of capital, uncertainties and
fluctuations in capital and securities markets, changes in tax laws and their
interpretation, legal proceedings, the availability of adequate insurance at
reasonable cost, the ability of customers to finance the purchase of homes, the
availability and cost of labor and materials, and weather conditions.

7. AVAILABILITY OF ROLLOVER OPTION AND EXCHANGE OPTION

o When this Trust is about to terminate, you may elect the Rollover Option
and acquire units of a future Mid-Cap Trust, if one is available (a
"Future Mid-Cap Trust"), or, at any time during the term of the Trust,
you may elect the Exchange Option and acquire units of certain other UBS
Financial Services Inc. unit trusts designated as "Exchange Trusts" in
Part B of this Prospectus under the heading "Public Offering of
Units--Exchange Option."

A-8

o Unitholders electing the Rollover Option may rollover their Units of
this Trust for units of a Future Mid-Cap Trust at no Initial Sales
Charge. Unitholders electing the Exchange Option may exchange their Units
of this Trust for units of one or more Exchange Trusts, at no Initial
Sales Charge. Units acquired either through the Rollover Option or the
Exchange Option will be subject to the Deferred Sales Charges, if any,
applicable to units of a Future Mid-Cap Trust or an Exchange Trust.

o If you elect the Rollover Option and so notify the Sponsor by February
22, 2006 (the "Rollover Notification Date"), your Units will be redeemed
and your proceeds from the sale of the Trust's Portfolio stocks will be
reinvested on February 23, 2006 (the "Special Redemption Rollover Date")
in units of a Future Mid-Cap Trust, if available.

o If you elect the Exchange Option, your units will be sold and the
proceeds of the sale will be used to acquire units of the Exchange
Trust(s) you have designated for purchase, if such units are available.

o If you decide not to elect either the Rollover Option or the Exchange
Option, you will receive a cash distribution after this Trust terminates.
Of course, you may redeem your Units at any time (see "Redemption" in
Part B of this Prospectus).

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

8. AVAILABILITY OF CONVERSION OPTION

If you own units of any unit investment trust sponsored by a company other
than UBS Financial Services Inc., and those units were initially offered at a
maximum applicable sales charge of at least 2.50%, you may elect to apply the
cash proceeds of the sale of those units directly to acquire, at a reduced
sales charge, units of this Trust or any Exchange Trust under certain
circumstances as described below in "Conversion Option" in Part B of this
Prospectus.

9. HOW WOULD THE INVESTMENT STRATEGY HAVE PERFORMED HISTORICALLY?

The following chart compares constructed performance of the Investment
Strategy stocks (but not of any actual Trust Portfolio) with actual performance
of the S&P MidCap 400 Index and the S&P 500 Index for the time period shown
below. Actual performance of this (or any other) Trust Portfolio, may vary from
that of the Index shown below for a variety of reasons. For example, each Trust
Portfolio is invested in a limited subset of Index stocks, and therefore its
performance may not keep pace with Index performance to the extent that the
Index is driven by stocks not held in such Portfolio. In addition, the
Portfolio stocks may have been chosen for specific criteria that are at odds
with the characteristics of the stocks driving the market at a given time. For
example, the Sponsor may have chosen growth stocks at a time when value stocks
are performing well. Furthermore, the Portfolio stocks are equally weighted
while the stocks in the Index are capitalization weighted. This constructed
performance is no assurance of future results of either the Investment Strategy
or any actual Trust Portfolio, including this Trust Portfolio.

----------
(1) To compute Total Returns, the Sponsor added changes in market value and
dividends that would have been received during the year, and then divided
the sum by the opening market value for one (1) year. Return from this or
any other Portfolio will differ from constructed Investment Strategy returns
for several reasons including the following:

o Actual Portfolio stocks were chosen on the second Business Day prior to
the date of this Prospectus, whereas the annual performance data above
measure performance beginning on January 1 and ending on December 31, of
each year;

o Each Portfolio bears brokerage commissions in buying and selling its
stocks whereas Investment Strategy returns do not reflect any commissions;

o Investment Strategy returns are for calendar years while Portfolios begin
and end on various dates;

o Units are bought and sold based on closing stock prices while Portfolios
may buy and sell stocks at various prices during the trading day;

o Portfolios may not be fully invested at all times; and

o Stocks in a Portfolio may not be weighted equally at all times.

10. IS THIS INVESTMENT APPROPRIATE FOR YOU?

Yes, if you are seeking capital appreciation over the life of the Trust by
investing in mid-cap common stocks issued by companies that the Sponsor
believes have capital appreciation potential. You can benefit from a 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 uncomfortable with the Investment Strategy, you
are unable or unwilling to assume the risks involved generally with equity
investments or mid-cap stocks in particular if you need high current income or
seek preservation of capital.

----------
(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 $1.00, based on the January 25, 2005 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 January 25, 2005 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 dividends 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 1.00% per 1,000 Units. The Initial Sales Charge
is reduced for purchasers of Units worth $50,000 or more. Also, certain
classes of investors are entitled to reduced sales charges (see "Public
Offering of Units" in Part B of this Prospectus). In addition, six (6)
monthly Deferred Sales Charges of $2.50 per 1,000 Units will be deducted
from the Trust's net asset value from the seventh (7th) through twelfth
(12th) months of the Trust's 15-month life, aggregating $15.00 per 1,000
Units during such period.

(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 $0.002 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 .25% of the net assets of the Trust is
a charge that compensates the Sponsor for the creation and development of
the Trust. It is computed based on the Trust's average daily net asset
value through the date of collection. (See "Creation and Development Fee"
in this Prospectus Part A.)

(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 $0.015 per Unit. As of the close of the
initial offering period, the Redemption Value will be reduced to reflect

THE UNITHOLDERS, SPONSOR AND TRUSTEE
EQUITY OPPORTUNITY TRUST,
MID-CAP SERIES 2

We have audited the accompanying Statement of Net Assets of Equity
Opportunity Trust, Mid-Cap Series 2, including the Schedule of

accepted in the United States. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the
Statement of Net Assets is free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts
and disclosures in the Statement of Net Assets. 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 Statement of Net Assets as of January 25, 2005. An
audit also includes assessing the accounting principles used and
significant estimates made by the Trustee, as well as evaluating the
overall Statement of Net Assets presentation. We believe that our audit
provides a reasonable basis for our opinion.

In our opinion, the Statement of Net Assets referred to above presents
fairly, in all material respects, the financial position of Equity
Opportunity Trust, Mid-Cap Series 2 at January 25, 2005, in conformity
with accounting principles generally accepted in the United States.

==========

----------
(a) The aggregate cost to the Trust of the stocks 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 stocks, an irrevocable letter of credit drawn on
JPMorganChase Bank, in the amount of $1,100,000 has been deposited with the
Trustee, Investors Bank & Trust Company, for the purchase of $990,020 aggregate
value of stocks in the initial deposits and for the purchase of stocks 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 $0.002 per Unit based upon the expected number of Units to be
created during the initial offering period. Certain stocks purchased with the
proceeds of the Public Offering Price will be sold by the Trustee at the
completion of the initial public offering period to reimburse the Sponsor for
Initial Organizational Costs actually incurred. If the actual Initial
Organizational Costs are less than the estimated amount, only the actual
Initial Organizational Costs will be deducted from the assets of the Trust. If,
however, the amount of the actual Initial Organizational Costs are greater than
the estimated amount, only the estimated amount of the Initial Organizational
Costs will be deducted from the assets of the Trust.

(c) Because the value of stocks at the Evaluation Time on the Initial Date
of Deposit may differ from the amounts shown in this Statement of Net Assets,
the number of Units offered on the Initial Date of Deposit will be adjusted
from the initial number of Units shown to maintain the $1.00 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 $2.50 per 1,000 Units,
payable monthly in six (6) equal installments by holders of record on the 2nd
Business Day prior to the tenth (10th) day of each month from the seventh (7th)
through twelfth (12th) months of the Trust's 15-month life for an aggregate
amount of $15.00 per 1,000 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 last installment date, 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 $25,000,000, the estimated
maximum Deferred Sales Charge would be $375,000.

PROSPECTUS PART B DATED JANUARY 25, 2005.

(THIS PAGE INTENTIONALLY LEFT BLANK.)

EQUITY OPPORTUNITY TRUST
MID-CAP SERIES 2
PROSPECTUS PART B

--------------------------------------------------------------------------------

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
Portfolio stocks ("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 such stocks
notwithstanding that, at the time of any such purchase, the stocks would no
longer be included as the 10 stocks on the S&P MidCap 400 Index ("Index")
selected pursuant to the criteria of the MidCap Series Investment Strategy or
the stocks are no longer included among the 400 current Index Stocks. Costs
incurred in acquiring such Additional Securities will be borne by the Trust.
Unitholders will experience a dilution of their investment as a result of such
brokerage fees and other expenses paid by the Trust during such deposits of
Additional Securities purchased by the Trustee with cash or cash equivalents
pursuant to instructions to purchase such Additional Securities. (See "The
Trust" and "Risk Factors and Special Considerations" in 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 $15.00 per 1,000 Units over
the Trust's 15-month life. For example, on the Initial Date of Deposit, on a
$1,000 investment, $990 is invested in the Trust and a $10 Initial Sales Charge
is collected. In addition, a Deferred Sales Charge of $2.50 per 1,000 Units
will be deducted from the Trust's net asset value on the 2nd Business Day prior
to the tenth (10th) day of each month from months seven (7) ( July, 2005)
through twelve (12) (December, 2005) of the Trust's life for a total of $15.00.
This deferred method of payment keeps more of the investor's money invested
over a longer period of time than would be the case if a single sales charge of
the same amount were collected on the initial date of purchase. The sales
charges are reduced on a graduated scale for volume purchasers and are reduced
for 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 the Initial Date of Deposit and any
date subsequent to the Initial Date of Deposit will vary from the Public
Offering Price set forth under "Essential Information Regarding the Trust" in
Part A of this Prospectus. Units redeemed or repurchased prior to the accrual
of the final Deferred Sales Charge installment will, except under certain
circumstances (see "Public Offering of Units" in this Prospectus Part B), have
the 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 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 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 at no
Initial Sales Charge (see "Reinvestment Plan" in this Prospectus Part B). (Such
Units, like all Units, will be subject to Deferred Sales Charges.) Upon
termination of the Trust, the Trustee will distribute to each Unitholder of
record on such date his or her pro rata share of the Trust's assets, less
expenses. See "Termination of the Trust" in this Prospectus Part B. The sale of
stocks in the Trust in the period prior

B-1

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 sell the stocks held in the Trust within fifteen (15) days of the Trust's
Mandatory Termination Date. Moneys held upon such sale or maturity of Trust
stocks 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 15 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.)

Rollover Option. If the Sponsor offers a new series of the Mid-Cap Trust
available for rollover by Unitholders in this Trust Series, Unitholders may
exercise their rollover option on February 23, 2006 (the "Special Redemption
Rollover Date"), and acquire units of the new series of the Mid-Cap Trust at a
reduced sales charge described under "Public Offering of Units--Rollover
Option" in this Prospectus Part B. The Sponsor reserves the right not to offer
new series of the Mid-Cap Trust and there is no guarantee that a new series
will be available on or after the Special Redemption Rollover Date. (See
"Public Offering of Units--Rollover Option" in this Prospectus Part B.)

Exchange Option. Unitholders may elect to exchange any or all of their
Units of this Trust for units of one or more of any series of unit investment
trust sponsored by UBS Financial Services Inc., at a reduced sales charge under
certain circumstances as described under "Public Offering of Units--Exchange
Option" 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 or her 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
Trust stocks 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* ("Indenture") dated as of the Initial Date of Deposit, between
UBS Financial Services Inc., as Sponsor, and Investors Bank & Trust Company, as
Trustee ("Trustee"). The objective of the Trust is capital appreciation through
an investment in 10 stocks in the S&P MidCap 400 Index which met the selection
criteria of the Investment Strategy at the time the Trust's Portfolio was
constructed. Of course, there can be no assurance that the objective of the
Trust will be achieved.

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

B-2

On the Initial Date of Deposit, the Sponsor deposited with the Trustee
confirmations of contracts for the purchase of Portfolio 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 stocks was
determined on the basis described under "Valuation" in this Prospectus Part B.
In exchange for the deposit of the contracts to purchase the stocks, 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 stocks in the Trust's Portfolio
(determined by reference to the number of shares of each issue of such 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 Initial Offering Period, 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 Portfolio stock.
The original proportionate relationship is subject to adjustment to reflect the
occurrence of a stock split or a similar event which affects the capital
structure of the issuer of a stock but which does not affect the Trust's
percentage ownership of the common stock equity of such issuer at the time of
such event, to reflect a merger or reorganization, to reflect the acquisition
of stocks or to reflect a sale or other disposition of a stock. It may not be
possible to maintain the exact original proportionate relationship among the
stocks deposited on the Initial Date of Deposit because of, among other
reasons, purchase requirements, changes in prices, brokerage commissions or
unavailability of stocks (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 Initial Offering Period must replicate the proportionate
relationship among the number of shares of each of the stocks 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 there from 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 Portfolio 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 stocks in the Trust will be
increased and the fractional undivided interest represented by each Unit in the
balance will be decreased. If any Units are redeemed, the aggregate value of
stocks 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 the elimination of its stock from the Portfolio except under
certain limited circumstances (see "Administration of the Trust--Portfolio
Supervision" in this Prospectus Part B). In addition, stocks will not be sold
by the Trust to take advantage of market fluctuations or changes in anticipated
dividend yields or rates of appreciation.

The issuers of Securities in the Trust's portfolio may be attractive
acquisition candidates pursuant to mergers, acquisitions and tender offers. In
general, tender offers involve a bid by an issuer or other

B-3

acquiror to acquire a stock pursuant to the terms of its offer. Payment
generally takes the form of cash, securities (typically bonds or notes), or
cash and securities. Pursuant to federal law a tender offer must remain open
for at least 20 days and withdrawal rights apply during the entire offering
period. Frequently offers are conditioned upon a specified number of shares
being tendered and upon the obtaining of financing. There may be other
conditions to the tender offer as well. Additionally, an offeror may only be
willing to accept a specified number of shares. In the event a greater number
of shares is tendered, the offeror must take up and pay for a pro rata portion
of the shares deposited by each depositor during the period the offer remains
open.

The Trust is not managed and has been structured with certain automatic
provisions contained in the Indenture in the event of a tender offer, merger or
reorganization as more fully described in the paragraph below. The foregoing
may interfere with the Trust's ability to maximize its objectives and,
consequently, a Unitholder's value. In such case, Unitholders shall have no
rights against the Trust, the Sponsor, the Trustee or any other party
associated with the Trust. The foregoing is not a disclaimer of
responsibilities under Section 36 of the Investment Company Act of 1940.

In the event the Trustee is notified of any vote to be taken or proposed
to be taken by holders of the securities held by the Trust in connection with
any proposed merger, reorganization, spin-off, split-off or split-up by the
issuer of securities held in the Trust, the Trustee shall use its best efforts
to vote the securities as closely as practicable in the same manner and in the
same general proportion as the Portfolio securities held by owners other than
the Trust are voted. In the event that an offer shall be made by any person to
exchange stock or securities for any Portfolio securities (including but not
limited to a tender offer), the Trustee shall reject such offer. If stock or
other securities are received by the Trustee, with or without cash, as a result
of any merger, reorganization, tender offer, spin-off, split-off, or split-up
by the issuer of Portfolio securities held in the Trust Fund or in exchange for
Portfolio securities (including any stock or securities received
notwithstanding the Trustee's rejection of an offer or received without an
initial offer), the Trustee, at the direction of the Sponsor, may retain or
sell such stock or securities in the Trust Fund. Any stock or securities so
retained shall be subject to the terms and conditions of the Indenture to the
same extent as the Portfolio securities originally deposited hereunder. The
Trustee shall give notice to the Unitholders of the retention of stock or
securities acquired in exchange for Portfolio securities within five Business
Days after such acquisition.

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

Investors should note that UBS Financial Services, UBS AG, UBS Securities
LLC and other affiliates, in their general securities business, act as agent or
principal in connection with the purchases and sales of equity securities,
including the stocks in the Trust's Portfolio, and may act as a market maker in
certain of such stocks. UBS Financial Services, UBS AG, UBS Securities LLC and
other affiliates also from time to time issue reports and may make
recommendations relating to equity securities, including the stocks in the
Trust's Portoflio, and have provided, and may continue to provide, investment
banking services to the issuers of the stocks in the Trust's Portfolio.

Investors should note in particular that the stocks in the Trust were
selected by the Sponsor two Business Days prior to 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 stocks originally selected through this process. This may be the case even
though the stocks may no longer be included in the current S&P MidCap 400 Index
or remain stocks which meet the selection criteria process of the Investment
Strategy. In addition, the Sponsor may continue to sell Trust Units even if UBS
Financial Services changes a recommendation relating to one or more stocks in
the Trust.

B-4

RISK FACTORS AND SPECIAL CONSIDERATIONS

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

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

Common stocks do not represent an obligation of the issuer. Therefore,
they do not offer any assurance of income or provide the degree of protection
of debt securities. The issuance of debt securities or even preferred stock by
an issuer will create prior claims for payment of principal, interest and
dividends which could adversely affect the ability and inclination of the
issuer to declare or pay dividends on its common stock or the rights of holders
of common stock with respect to assets of the issuer upon liquidation or
bankruptcy. Unlike debt securities which typically have a stated principal
amount payable at maturity, common stocks do not have a fixed principal amount
or a maturity. Additionally, the value of the stocks in the Trust's Portfolio
may be expected to fluctuate over the life of the Trust.

Any distributions of income to Unitholders will generally depend upon the
declaration of dividends by the issuers of Trust stocks 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. Portfolio 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 or
political conditions, and the prices of equity securities in general and the
Portfolio 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.

Investors should note that the Trust's objective may not be realized
because the stocks held in the 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.
Additionally, there is no guarantee that the Investment Strategy will be
successful.

The Sponsor's buying and selling of the Trust stocks, especially during
the initial offering of Units of the Trust, or to satisfy redemptions of Units
or to reimburse the Sponsor for the Initial Organizational Costs or to pay the
Creation and Development Fee or the accrued Deferred Sales Charge to the
Sponsor, may impact upon the value of the Portfolio stocks and the Units.
During the Initial Public Offering the Sponsor may also purchase large blocks
of the Portfolio stocks in connection with the offering of other investment
funds holding substantially the same portfolio of stocks as the Trust. The
Sponsor's acquisition of certain of the stocks in open market purchases may
have the unintended result of increasing the market price for such stocks
during the period that the Sponsor is acquiring stocks for the Trust.

B-5

Additional Securities may be purchased by the Trust when additional Units
are offered to the public or for the Reinvestment Plan. 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 stock 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 stock and more or less of the other
stocks in the Trust. Unitholders will be at risk because of price fluctuations
during this period since if the price of shares of a stock increases,
Unitholders will have an interest in fewer shares of that stock, and if the
price of a stock decreases, Unitholders will have an interest in more shares of
that stock, than if the stock had been purchased on the date cash was deposited
with instructions to purchase the stock. 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, such as brokerage fees,
incurred in connection with the acquisition of Additional Securities will be
borne by the Trust and will affect the value of every Unitholder's Units. Your
Units will be worth less as a result of the Trust's payment of brokerage fees
and other expenses.

Investors should note that the Trust has adopted an internal policy that
prohibits the ownership of any issue of Portfolio stock by all Mid-Cap Trusts
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 Mid-Cap Trust, including those to be created for
Reinvestment Plan purposes, until such time as all Mid-Cap Trusts, 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 Portfolio stock to be deposited on
the Initial Date of Deposit or within 90 days of such date fails, cash held or
available under a letter or letters of credit, attributable to such failed
contract may be reinvested in another stock or stocks having characteristics
sufficiently similar to the stocks originally deposited (in which case the
original proportionate relationship shall be adjusted) or, if not so
reinvested, distributed to Unitholders of record on the last day of the month
in which the failure occurred. The distribution will be made approximately
fifteen (15) 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.

To the extent that a significant number of Unitholders exercise their
Rollover Option on the Special Redemption Rollover Date, the Trust will
experience a correspondingly significant redemption at such time thereby
reducing the size of the Trust. Such redemptions may increase the expense
ratios for Unitholders who hold their Units until the Mandatory Termination
Date (see "Public Offering of Units--Rollover Option" in this Prospectus Part
B).

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 Portfolio stocks 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).

B-6

Although the Trust is not managed, the Trust Portfolio may not remain
constant during the life of the Trust. The Trustee may be required to sell
Portfolio securities to pay Trust expenses, to tender Portfolio securities
under certain circumstances or to sell Portfolio securities in the event
certain negative events occur. The sale of securities from the Trust in the
period prior to termination and upon termination may result in a lower amount
than might otherwise be realized if such sale were not required at such time
due to impending or actual termination of the Trust. For this reason, among
others, the amount you receive upon termination may be less than the amount you
paid. If many investors sell their Units, the Trust will have to sell Portfolio
securities. These sales could result in losses for the Trust and increase your
share of Trust expenses. Due to merger and acquisition activity, as well as the
reasons described above, the Trust may have to tender or sell securities in the
Trust Portfolio. If the Trust must tender or sell Portfolio securities for any
of these reasons, such tenders or sales may reduce the diversification of your
investment.

A number of the stocks in the Trust's Portfolio 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
stocks from such clients' accounts in instances where a sale of such stocks by
the Trust would be impermissible, such as to maximize return by taking
advantage of attractive market fluctuations in such stocks. As a result, the
amount realized upon the sale of the stocks from the Trust's Portfolio may not
be the highest price attained for an individual stock during the life of the
Trust.

The Sponsor may have acted as underwriter, manager, or co-manager of a
public offering of the stocks deposited into the Trust's Portfolio on the
Initial Date of Deposit, or as an adviser to one or more of the issuers of the
stocks, during the last three years. The Sponsor or affiliates of the Sponsor
may serve as specialists in the Trust's Portfolio stocks on one or more stock
exchanges and may have a long or short position in any of these stocks 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 stocks 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 Trust's Portfolio stocks 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
Trust's Portfolio stocks or in options on them.

Except as may be disclosed in Part A of this Prospectus, 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 Trust, although
pending litigation may have a material adverse effect on the value of stocks 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 stocks in the Portfolio or the issuers of such stocks.
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 Trust's Portfolio stocks to achieve their business goals.

Certain of the Trust's Portfolio 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-7

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 LLP, 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
Portfolio stocks, gains or losses upon dispositions of Securities by the Trust
and a pro rata share of the expenses of the Trust (see "Tax Law Applicable to
Dividends and Long-Term Capital Gain," below).

Distributions with respect to Portfolio stock, to the extent they do not
exceed current or accumulated earnings and profits of the distributing
corporation (as calculated under the U.S. tax accounting principles), will be
treated as dividends to the Unitholders and will be subject to income tax at
ordinary rates.

To the extent distributions with respect to a Portfolio 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 Portfolio stock.

B-8

A Unitholder who is an individual, estate or trust may be disallowed
certain "miscellaneous" itemized deductions, including compensation paid to the
Trustee and administrative expenses of the Trust, to the extent these itemized
deductions, in the aggregate, do not exceed two percent of the Unitholder's
adjusted gross income. Thus, a Unitholder's taxable income from an investment
in Units may further exceed amounts distributed to the extent amounts are used
by the Trust to pay expenses.

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

Corporate Dividends-Received Deduction. Corporate holders of Units may be
eligible for the dividends-received deduction with respect to their pro rata
share of dividends received by the Trust from U.S. corporations, if any,
subject to various limitations. 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.

Tax Law Applicable to Dividends and Long-Term Capital Gain. Under tax
legislation enacted during 2003, dividends received by individual U.S. Holders,
and long-term capital gain realized by individual U.S. Holders, generally are
subject to a reduced maximum tax rate of 15 percent through December 31, 2008.
The reduced rate on capital gains applies to sales and exchanges on or after
May 6, 2003 and the reduced rates on dividend income to dividends received
after December 31, 2002. The rate reduction does not apply to dividends
received in respect of certain short-term or hedged positions or in certain
other situations. U.S. Holders should consult their own tax advisors regarding
the implications of these rules in light of their particular circumstances.

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 under "Essential Information Regarding the Trust" in Part A of this
Prospectus) due to fluctuations in the value of the Portfolio 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.

B-9

Sales Charge and Volume Discount. Units will be charged a Total Sales
Charge of approximately 2.50% per 1,000 Units which is a combination of the
Initial and Deferred Sales Charges. The Initial Sales Charge will be 1.00% of
the Public Offering Price. Assuming a purchase on the Initial Date of Deposit
of 1,000 Units, the Initial Sales Charge will be $10.00. Commencing in the
seventh (7th) month and continuing through the twelfth (12th) month of the
Trust's fifteen (15) month life, the Total Deferred Sales Charge per 1,000
Units will be $15.00 ($2.50 per month), approximately 1.50% of the Public
Offering Price. Because the Deferred Sales Charge per 1,000 Units is $15.00
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 you buy 1,000 Units for $1,000 (including
the Initial Sales Charge of $10.00) and hold the Units until the Trust
terminates, you would pay a Total Sales Charge of $25.00 or 2.50% of the
acquisition price for such Units. If, however, you buy 1,000 Units for $900
(including the Initial Sales Charge of $9.00), you will pay a Total Sales
Charge of $24.00 or 2.67% of the acquisition price for such Units. Conversely,
if an investor bought 1,000 Units for $1,100 (including the Initial Sales
Charge of $11.00), such investor would pay a total of $26.00 or 2.36% of the
acquisition price for such Units.

The monthly Deferred Sales Charge is a charge of $2.50 per 1,000 Units and
is accrued in six (6) monthly installments during the life of the Trust. Units
purchased after an accrual date for a Deferred Sales Charge installment are not
subject to any Deferred Sales Charge installments prior to such purchase date.
Units redeemed or repurchased prior to the accrual of the final Deferred Sales
Charge installment will have the amount of any installments remaining deducted
from the redemption or repurchase proceeds 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 Portfolio securities to make this payment. It is anticipated
that 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 Portfolio securities from the several installment accrual
dates to the date of actual sales of such securities to satisfy this liability.

A discount in the sales charge is available to volume purchasers of Units
due to economies of scale in sales effort and sales related expenses relating
to volume purchases. The sales charge applicable to volume purchasers of Units
is reduced on a graduated scale as set forth below for sales made on a single
day to any person of at least $50,000 or 50,000 Units, applied on whichever
basis is more favorable to the purchaser.

----------
* The Total 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.

B-10

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

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

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

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

Rollover Option. If the Sponsor offers a new series of the Mid-Cap Trust
available for rollover by Unitholders in this Trust Series, Unitholders, in
lieu of redeeming their Units or receiving liquidation proceeds upon
termination of this Trust series, may elect, by informing the Sponsor no later
than 4 pm EST on February 22, 2006 (the "Rollover Notification Date"), to
exchange their Units of this Trust series for units of the next series of the
Mid-Cap Trust on the Special Redemption Rollover Date at no Initial Sales
Charge. Units acquired by means of the Rollover Option will, of course, be
subject to the Deferred Sales Charges aggregating $15.00 per 1,000 Units. No
election to rollover may be made prior to 40 days before the Rollover
Notification Date and any Rollover election will be revocable at any time prior
to 4 pm EST on the Rollover Notification Date. It is expected that the terms of
the new Trust series will be substantially the same as those of this Trust
series. The Sponsor reserves the right not to offer new series of the Mid-Cap
Trust and there is no guarantee that a new Trust series will be available on
the Rollover Notification Date.

Rollovers 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.

A rollover of a Unitholder's Units will be accomplished by the in-kind
redemption of such Units, followed by the sale of the Trust's Portfolio
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 of the next Mid-Cap Series at their then-current net asset
value.

Certain of the underlying securities held in the Portfolio of an existing
Mid-Cap Trust may also be included in the portfolio of a future Mid-Cap Trust
made available to Unitholders electing to rollover their Units on the Special
Redemption Rollover Date. In such cases, a direct sale of these stocks from one
Mid-Cap Trust to a new Mid-Cap Trust will be permitted pursuant to an SEC
exemptive order. 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 Portfolio of the existing
Mid-Cap Trust which will not be held in the portfolio of the new Mid-Cap Trust
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 new Mid-Cap Trust.

B-11

The Sponsor intends to direct the sale of the Portfolio 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 Portfolio 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 Portfolio 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 Rollover Option may realize taxable capital gains
but will not be entitled to a deduction for certain capital losses realized.
Moreover, because of the rollover 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 Rollover Option.

The Sponsor reserves the right to modify, suspend or terminate this
Rollover Option at any time with notice to Unitholders. In the event the
Rollover Option is not available to a Unitholder at the time he or she wishes
to exercise it, the Unitholder will be immediately notified and no action will
be taken with respect to his or her Units without further instruction from the
Unitholder. If the Sponsor decides not to offer the Rollover Option, the
success of the Investment Strategy may be impaired.

To exercise the Rollover Option, a Unitholder should notify the Sponsor by
no later than 4 pm EST on the Rollover Notification Date that such Unitholder
wishes to exercise the Rollover Option and to use the proceeds from the sale of
Portfolio securities in respect of his or her in-kind redemption of Units of
this Trust to purchase Units of the next Mid-Cap Trust from the Sponsor. If
Units of the next Mid-Cap 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 next Mid-Cap Trust.

Unitholders who do not exercise the Rollover Option, or otherwise sell,
exchange 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 Rollover 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
Rollover 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. 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 Rollover Option, Section 17(a) would prohibit the direct sale of
securities from one Mid-Cap Series to another on the books of the Trustee
without an exemptive order. The Sponsor has received exemptive orders which the
Sponsor believes permit the offering of this Rollover Option, but no assurance
can be given that the SEC will concur with the Sponsor's position and
additional regulatory approvals may be required.

Exchange Option. Unitholders may elect to exchange any or all of their
Units of this Mid-Cap Series of the Equity Opportunity Trust for units of one
or more of any series of The Municipal Bond Fund ("UBS Series"); The Municipal
Bond Trust ("National Series"); The Municipal Bond Trust, Multi-State Program
("Multi-State Series"); The Municipal Bond Trust, California Series
("California Series"); The

B-12

Corporate Bond Trust ("Corporate Series"); UBS Pathfinders Trust ("Pathfinders
Series"); the UBS Federal Government Trust ("Government Series"); The Municipal
Bond Trust, Insured Series ("Insured Series"); or the Equity Opportunity Trust
("Equity Series") (collectively referred to as the "Exchange Trusts"), at a
Public Offering Price for the Units of the Exchange Trusts to be acquired based
on a reduced sales charge under certain circumstances as discussed below.
Unitholders of this Trust are not eligible for the Exchange Option into any
Exchange Trust designated as a rollover series following the cut-off date
announced by the Sponsor prior to termination of such Exchange Trust. The
purpose of such reduced sales charge is to permit the Sponsor to pass on to the
Unitholder who wishes to exchange Units the cost savings resulting from such
exchange of Units. The cost savings result from reductions in time and expense
related to advice, financial planning and operational expenses required for the
Exchange Option.

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

The Sponsor will permit exchanges at the reduced sales charge as described
below provided there is either a primary market for Units or a secondary market
maintained by the Sponsor in both the Units of this Trust and units of the
applicable Exchange Trust and there are units of the applicable Exchange Trust
available for sale. While the Sponsor has indicated that it intends to maintain
a market for the Units of the respective Trusts, there is no obligation on its
part to maintain such a market. Therefore, there is no assurance that a market
for Units will in fact exist on any given date at which a Unitholder wishes to
sell his or her Units of this series and thus there is no assurance that the
Exchange Option will be available to a Unitholder. Exchanges will be effected
in whole Units only. Any excess proceeds from Unitholders' Units being
surrendered will be returned. Unitholders will be permitted to advance new
money in order to complete an exchange to round up to the next highest number
of Units.

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

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

B-13

Unitholders may exercise the Exchange Option only within 30 days following
the sale of their Units of this series to the Sponsor. Thereafter, Units of any
Exchange Trust will be purchased at the then-current sales charge for such
Units, rather than at the reduced sales charge as provided under the Exchange
Option. To exercise the Exchange Option, a Unitholder should notify the Sponsor
of his or her desire to exercise the Exchange Option and to use the proceeds
from the sale of his or her Units of this series to purchase units of one or
more of the Exchange Trusts. If units of the applicable outstanding series of
the Exchange Trust are at that time available for sale, and if such units may
lawfully be sold in the state in which the Unitholder resides, the Unitholder
may select the series or group of series for which he or she desires his or her
investment to be exchanged. The Unitholder will be provided with a current
prospectus or prospectuses relating to each series in which he or she indicates
interest.

The exchange transaction will operate in a manner essentially identical to
any secondary market transaction, i.e., Units will be repurchased at a price
based on the Trust Fund Evaluation per Unit (see "Public Offering of
Units--Secondary Market"). Units of the Exchange Trust, however, will be sold
to the Unitholder at a reduced sales charge as discussed above. Exchange
transactions will be effected only in whole units; thus, any proceeds not used
to acquire whole units will be paid to the selling Unitholder.

Conversion Option. Owners of units of any registered unit investment trust
sponsored by others which was initially offered at a maximum applicable sales
charge of at least 2.5% (a "Conversion Trust") may elect to apply the cash
proceeds of the sale or redemption of those units ("Conversion Trust Units")
directly to acquire available units of any Exchange Trust having an up-front
sales load at a reduced sales charge of $15 per Unit, per 100 Units in the case
of Exchange Trusts having a Unit price of approximately $10, or per 1,000 Units
in the case of Exchange Trusts having a Unit price of approximately $1, subject
to the terms and conditions applicable to the Exchange Option (except that no
secondary market is required for Conversion Trust Units). Owners of Conversion
Trust Units also will be permitted to use the cash proceeds received from the
sale or redemption of those units to acquire units of this Trust, or any other
Deferred Sales Charge Units, at their then-current net asset value, with no
Initial Sales Charge imposed. Deferred Sales Charge Units acquired through the
Conversion Option will continue to be subject to the deferred sales charge
installments remaining on those Deferred Sales Charge Units so acquired. In the
case of existing UBS Financial Services Inc. clients, Unitholders may exercise
the Conversion Option only within 30 days following the sale of their
Conversion Trust Units to the Sponsor. Owners of units of any registered unit
investment trust sponsored by others may exercise the Conversion Option only
within 30 days following the sale of their Conversion Trust Units to any dealer
other than UBS Financial Services Inc., and such dealer must apply the cash
proceeds of the sale of those units to acquire units of any Exchange Trust. In
addition, any dealer other than UBS Financial Services Inc. must certify to the
Sponsor that the purchase of units of the Exchange Trust is being made pursuant
to, and is eligible for, the Conversion Option as described herein. To exercise
this Conversion Option, the owner should notify his or her retail broker. He or
she will be given a prospectus for each series in which he or she indicates
interest and for which units are available. The dealer must sell or redeem the
units of the Conversion Trust. The dealer will be entitled to two-thirds of the
applicable reduced sales charge. The Sponsor reserves the right to modify,
suspend or terminate the Conversion Option at any time with notice, including
the right to increase the reduced sales charge applicable to this option (but
not in excess of $5 more per Unit, per 100 Units or per 1,000 Units, as
applicable, than the corresponding fee then being charged for the Exchange
Option). For a description of the tax consequences of a conversion see "Public
Offering of Units--Exchange Option" in this Prospectus Part B.

Distribution of Units. The minimum purchase in the initial public offering
is $250. Only whole Units may be purchased.

B-14

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 during the initial
offering period, as set forth in the table below.

AGGREGATE DOLLAR VALUE OF UNITS CONCESSION
--------------------------------- -----------
Less than $50,000.............. 2.20%
$50,000 to $99,999............. 2.00%
$100,000 to $249,999........... 1.60%
$250,000 to $999,999........... 1.40%
$1,000,000 or more............. 0.80%

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 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 or her Units should inquire of
his or her 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 Portfolio 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 Portfolio stocks, determined by the Trustee as described under "Valuation"
in this Prospectus Part B. The cost of Portfolio 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 Portfolio securities upon
their delivery may be used in the Sponsor's business subject to the limitations
of Rule 15c3-3 under the Securities Exchange Act of 1934 and may be of benefit
to the Sponsor.

B-15

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

REDEMPTION

Units may be tendered to Investors Bank & Trust Company for redemption at
its office in person, or by mail at Hancock Tower, 200 Clarendon Street,
Boston, MA 02116 upon payment of any transfer or similar tax which must be paid
to effect the redemption. At the present time, there are no such taxes. No
redemption fee will be charged by the Sponsor or Trustee, but any remaining
Deferred Sales Charge installments will be deducted at that time. A written
instrument of redemption must be signed by the Unitholder. Unitholders must
sign exactly as their names appear on the records of the Trustee with
signatures guaranteed by an eligible guarantor institution or in such other
manner as may be acceptable to the Trustee. In certain instances the Trustee
may require additional documents such as, but not limited to, trust
instruments, certificates of death, appointments as executor or administrator,
or certificates of corporate authority. Unitholders should contact the Trustee
to determine whether additional documents are necessary. Units tendered to the
Trustee for redemption will be cancelled, if not repurchased by the Sponsor.

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

A redemption request is deemed received on the 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 Portfolio 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, Portfolio Stocks will be
sold pro rata, to the extent possible, and if not possible, the Trustee may
designate Portfolio 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 Portfolio Stocks to the
redeeming Unitholder. When Portfolio Stocks are so distributed, a proportionate
amount of each such Stock will be distributed, rounded to avoid the
distribution of fractional shares and using cash

B-16

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. Portfolio 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 Portfolio Stocks distributed into cash. The availability of
redemption "in kind" is subject to compliance with all applicable laws and
regulations, including the Securities Act of 1933.

To the extent that Portfolio 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 Portfolio 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 Portfolio 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.

To the extent that a significant number of Unitholders exercise the
Rollover Option on the Special Redemption Rollover Date, the Trust will
experience a correspondingly significant redemption at such time, thereby
reducing the size of the Trust. Such redemption may increase the expense ratios
for Unitholders who hold their Units until the Mandatory Termination Date. See
"Public Offering of Units--Rollover Option" in this Prospectus Part B.

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 ("Trust Fund Evaluation") per
Unit at the Evaluation Time set forth under "Essential Information Regarding
the Trust" in Part A of this Prospectus (1) on each Business Day as long as the
Sponsor is maintaining a bid in the secondary market, (2) on the Business Day
on which any Unit is tendered for redemption, (3) on any other day desired by
the Sponsor or the Trustee and (4) upon termination, by adding (a) the
aggregate value of the Trust's Portfolio Securities and other assets determined
by the Trustee as set forth below, (b) cash on hand in the Trust, including
dividends receivable on Portfolio 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 Portfolio 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, if any, owed to the
Sponsor in reimbursement of Initial Organizational Costs and the Creation and
Development Fee 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

B-17

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 NASDAQ Stock Market, such evaluation shall be based on the closing sale
price on that day or, in the case of the NASDAQ, at the official closing price
on that day (unless the Trustee deems such price inappropriate as a basis for
evaluation) on the exchange which is the principal market thereof (deemed to be
the New York Stock Exchange in the case of the domestic Stocks if such Stocks
are listed thereon), (2) if there is no such appropriate closing sales price on
such exchange or system, at the mean between the closing bid and asked prices
on such exchange or system (unless the Trustee deems such price inappropriate
as a basis for evaluation), (3) if the Stocks are not so listed or, if so
listed and the principal market therefor is other than on such exchange or
there are no such appropriate closing bid and asked prices available, such
evaluation shall be made by the Trustee in good faith based on the closing sale
price in the over-the-counter market (unless the Trustee deems such price
inappropriate as a basis for evaluation) or (4) if there is no such appropriate
closing price or if the closing price is deemed inappropriate as a basis for
evaluation, 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, (d) on the basis of a valuation by the Sponsor or (e) 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 Trust's Portfolio 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 Portfolio
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
Portfolio Securities made to reimburse the Sponsor for the Initial
Organizational Costs.

EXPENSES OF THE TRUST

The Sponsor will receive a fee, which is earned for portfolio supervisory
services, and which is based upon the largest number of Units outstanding
during the calendar year. The Sponsor's fee, which is not to exceed $0.00035
per Unit per calendar year, may exceed the actual costs of providing portfolio
supervisory services for the Trust, but at no time will the total amount it
receives for portfolio supervisory services rendered to all series of the
Equity Opportunity Trust in any calendar year exceed the aggregate cost to it
of supplying such services in such year.

For its services as Trustee and Evaluator, the Trustee will be paid in
monthly installments, annually $0.00170 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 $0.00127 per Unit, which
include, but are not limited to certain mailing, printing, and audit expenses.
Expenses in excess of this

B-18

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 or to the extent the Trustee, including its affiliates, acting in its
individual capacity, provides other services, such as brokerage services, to
the Trust.

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

In addition to the above, the following charges are or may be incurred by
the Trust and paid from the Income Account, or, to the extent funds are not
available in such Account, from the Capital Account (see "Administration of the
Trust--Accounts" in 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 willful 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
$0.00050 per Unit. Unitholders covered by the audit during the year may receive
a copy of the audited financial statements upon request.

The fees and expenses set forth above are payable out of the Trust and
when unpaid will be secured by a lien on the Trust. Based upon the last
dividend paid prior to the Initial Date of Deposit, dividends on the Trust's
Portfolio 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 Trust's Portfolio Stocks are not sufficient to meet the expenses of the
Trust, the Trustee is authorized to sell such Securities to meet the expenses
of the Trust. Portfolio 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 and will make distributions from the Capital Account to
Unitholders of record on the preceding Record Date on the Distribution Dates
set forth in "Essential Information Regarding the Trust" in Part A of this
Prospectus. Distributions of less than $0.0050 per Unit need not be made from
the Capital Account on any

B-19

Distribution Date. See "Essential Information Regarding the Trust" in Part A of
this Prospectus. Whenever required for regulatory or tax purposes, the Trustee
will make special distributions of any dividends or capital on special
Distribution Dates to Unitholders of record on special Record Dates declared by
the Trustee.

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

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

Upon termination of the Trust, each Unitholder of record on such date will
receive his or her 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.) As discussed above
under "Public Offering of Units--Rollover Option" and "Public Offering of
Units--Exchange Option", Unitholders in lieu of receiving his or her pro rata
share of such amounts, may acquire Units of a Rollover Trust or an Exchange
Trust.

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 or her broker, dealer or financial institution to determine
whether he may participate in the Reinvestment Plan. Under the Reinvestment
Plan, the Units acquired for current Unitholders will be either Units already
held in inventory by the Sponsor or new Units created by the Sponsor's deposit
of Additional Securities, contracts to purchase Additional Securities or cash
(or a bank letter of credit in lieu of cash) with instructions to purchase
Additional Securities. Deposits or purchases of Additional Securities will be
made so as to maintain the percentage relationships of shares of Stocks, except
as discussed under "The Trust" in this Prospectus Part B. If a Unitholder
elects to participate in the Reinvestment Plan, in addition to the reinvestment
Units he or she 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

B-20

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.

ADMINISTRATION OF THE TRUST

Accounts. All dividends and interest received on the Trust's Portfolio
Securities, proceeds from the sale of such 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 Portfolio Stocks 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, (2) the Creation and Development Fee and (3) 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, (2)
paying the Creation and Development Fee and (3) 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 Portfolio Securities. Upon notification from the Sponsor that
the initial offering period is terminated, the Trustee, at the direction of the
Sponsor, will cause the sale of Portfolio Securities in an amount equal to the
Initial Organizational Costs and the Creation and Development Fee 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 Portfolio
Securities to pay such sales charges until after the Special Redemption
Rollover Date.

The Trustee may establish reserves ("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 Portfolio Securities 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 2005,
the Trustee will furnish each person who was a Unitholder at any time during
the calendar year an annual report containing the

B-21

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 Portfolio Securities
sold during such year and the Portfolio Securities held at the end of such
year; (3) the Trust Fund Evaluation per Unit, based upon a computation thereof
on the 31st day of December; and (4) amounts distributed to Unitholders during
such year.

Portfolio Supervision. In accordance with the Investment Company Act of
1940 and the provisions of the Indenture, the Portfolio of the Trust is not
"managed" by the Sponsor or the Trustee. The Indenture provides that the
Sponsor may (but need not) direct the Trustee to dispose of a Portfolio
Security upon the occurrence of any materially adverse market or credit
factors, that in the opinion of the Sponsor, make the retention of such
Securities not in the best interest of the Unitholders.

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. The Trustee may also dispose of Securities where necessary
to pay Initial Organizational Costs, the Creation and Development Fee, Trust
expenses, Deferred Sales Charge installments or to satisfy redemption requests
as directed by the Sponsor and in a manner necessary to maximize the objectives
of the Trust, or if not so directed in its own discretion.

AMENDMENT OF THE INDENTURE

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

The Indenture may also be amended by the Trustee and the Sponsor without
the consent of any of the Unitholders to implement a program to reinvest cash
proceeds received by the Trust in connection with corporate actions and in
other situations, when and if the Sponsor receives a favorable response to the
no-action letter request which it intends to submit to the Division of
Investment Management at the SEC discussed above (see "Distributions" in 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 Portfolio Stocks upon
completion of the deposit of such 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.

Under normal circumstances it is anticipated that the Trustee will sell
the Portfolio Securities held in the Trust within 15 days of the termination of
the Trust. Moneys held upon the sale of Portfolio Securities

B-22

may be held in non-interest bearing accounts created by the Indenture until
distributed and will be of benefit to the Trustee. Upon termination of the
Trust and 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, the Trustee will then distribute to
each Unitholder such Unitholder's pro rata share in the Income and Capital
Accounts. The sale of Portfolio Stocks held 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, UBS Financial Services Inc., is a corporation organized under
the laws of the State of Delaware. The Sponsor is a member firm of the New York
Stock Exchange, Inc. as well as other major securities and commodities
exchanges and is a member of the National Association of Securities Dealers,
Inc. The Sponsor, its parent and other affiliates are engaged in security and
commodity brokerage businesses 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 members of various selling groups or
as agents 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 Sponsor is an affiliate of UBS Securities LLC and a wholly-owned
subsidiary of UBS AG. The combined U.S. research team consists of approximately
66 senior analysts following over 850 companies. Together, the Sponsor and its
affiliates have a total of more than 400 analysts worldwide.

The Sponsor, UBS AG, UBS Securities LLC or other affiliates of the Sponsor
(collectively, "Affiliated Entities") may have acted as underwriter, manager or
co-manager of a public offering of the Securities during the last three years;
they may serve as specialists in the Securities on one or more stock exchanges
and may have a long or short position in any of the Securities or options on
any of them, and may be on the opposite side of public orders executed on the
floor of an exchange where the Securities are listed. An officer, director or
employee of any of the Affiliated Entities may be an officer or director of one
or more of the issuers of the Securities. Each of the Affiliated Entities may
trade for its own account as an odd-lot dealer, market maker, block positioner
and/or arbitrageur in any of the Securities or in options on them. Each of the
Affiliated Entities, its directors, elected officers and employee benefits
programs may have either a long or short position in any Securities or options
on them.

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
Stocks 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.

B-23
