- ------------------------
    *The Date of Deposit. The Indenture was signed and the initial deposit of
Securities with the Trustee was made on the Date of Deposit.
   **Each Security listed on a securities exchange is valued at the last closing
sale price on the relevant stock exchange (generally 4:00 p.m. Eastern time on
the New York Stock Exchange, 11:30 a.m. Eastern time on the London Stock
Exchange and 3:30 a.m. Eastern time on the Hong Kong Stock Exchange) on the Date
of Deposit, or if no such price exists at the closing offer price thereof. The
aggregate U.S. dollar value of the Foreign Securities in the Trust is based on
the offering side of the currency exchange rate for the British pound sterling
or the Hong Kong dollar at the Evaluation Time on the Date of Deposit.
  ***The sales charge consists of an Initial Sales Charge and a Deferred Sales
Charge. The Initial Sales Charge is computed by deducting the Deferred Sales
Charge ($20.00 per 100 Units) from the aggregate sales charge (a maximum of
2.90% of the Public Offering Price); thus on the date of this Summary of
Essential Information, the Initial Sales Charge is $7.64 per 100 Units or 0.80%
of the Public Offering Price. The Initial Sales Charge paid by a Unit Holder may
be more or less than $7.64 per 100 Units because of the fluctuation of the value
of the Securities from that on the Date of Deposit. The Initial Sales Charge is
reduced on a graduated basis on purchases of $25,000 or more (see "Public
Offering of Units--Volume Discount"). The Deferred Sales Charge is paid through
reduction of Trust assets by $2.00 per 100 Units on each Deferred Sales Charge
Payment Date through the sale of Securities on each such date or distribution of
cash available in the Principal Account for such payment. On a repurchase,
redemption or exchange of Units before the last Deferred Sales Charge Payment
Date, any remaining Deferred Sales Charge payments will be deducted from the
proceeds. Units purchased pursuant to the Reinvestment Program are subject to
that portion of the Deferred Sales Charge remaining at the time of reinvestment
(see "Reinvestment Program").
 ****This price is computed as of the Date of Deposit and may vary from such
price on the date of this Prospectus or any subsequent date. The Public Offering
Price per Unit is based on the aggregate U.S. dollar value of the Securities
computed on the basis of the offering side of the relevant currency exchange
rate. No sales to investors will be executed on such date at this price.
Additional Securities will be deposited after the Date of Deposit which
Securities will be valued generally as of 4:00 p.m. Eastern time and Units will
be sold to investors at a Public Offering Price based on this valuation.
 *****This price is computed as of the Date of Deposit and may vary from such
price on the date of this Prospectus or any subsequent date. This price reflects
deductions for remaining Deferred Sales Charge payments ($20.00 per 100 Units
initially). In addition, after the initial offering period, the repurchase and
cash redemption prices will be further reduced to reflect the Trust's estimated
costs of liquidating Securities to meet the redemption, currently estimated at
$1.15 per 100 Units.
******See: "Expenses and Charges" herein. The fee and the expenses accrue daily
and are payable on each Distribution Date. Estimated dividends from the
Securities, based on the last dividends actually paid, are expected by the
Sponsor to be sufficient to pay the estimated expenses of the Trust. In addition
to the Trustee's fee, brokerage costs borne by the Trust in connection with the
purchase of Securities by the Trustee with cash deposited in the Trust are
currently estimated at $0.90 per 100 Units.
    +The number of Units will be increased as the Sponsor deposits additional
Securities into the Trust. See "Introduction", in Part B.
   ++The final distribution will be made within 5 business days following the
receipt of proceeds from the sale of all Portfolio Securities. (See:
"Administration of the Trust--Termination".)
  +++The cost of preparation and printing of the Indenture, Registration
Statement and other documents relating to the Trust, Federal and State
registration fees and costs, initial fees of the Trustee, and legal and auditing
expenses will be paid by the Trust and, therefore, will be borne by Unit
Holders. These organizational expenses will be amortized over the life of the
Trust. Organizational expenses per Unit have been estimated based on a Trust
with projected total assets of $25 million. To the extent the assets of the
Trust are less than such amount, the organizational expense per Unit will be
greater than the estimate shown.

The Example assumes reinvestment of all dividends and distributions and utilizes a 5% annual rate of
return as mandated by Securities and Exchange Commission regulations applicable to mutual funds. For
purposes of the Example, the Deferred Sales Charge imposed on reinvestment of dividends is not reflected
until the year following payment of the dividend; the cumulative expenses would be higher if sales
charges on reinvested dividends were reflected in the year of reinvestment. Because the reductions to the
repurchase and cash redemption prices described in footnote (*****) on page (ii) apply only to the
secondary market, these reductions have not been reflected in the figures above. The Example should not
be considered a representation of past or future expenses or annual rate of return; the actual expenses
and annual rate of return may be more or less than those assumed for purposes of the Example.

- ------------------------
(a)  The Initial Sales Charge is actually the difference between 2.90% and the
     Deferred Sales Charge ($20.00 per 100 Units) and would exceed 0.90% if the
     Public Offering Price exceeds $1,000 per 100 Units.
 
(b)  The actual fee is $2.00 per month per 100 Units, irrespective of purchase
     or redemption price, paid on each Deferred Sales Charge Payment Date. If a
     Holder sells Units before all of these payments have been made, the balance
     of the Deferred Sales Charge will be paid from the sales proceeds. If the
     Unit purchase price exceeds $10 per Unit, the Deferred Sales Charge will be
     less than 2.00%; if the Unit purchase price is less than $10 per Unit, the
     Deferred Sales Charge will exceed 2.00%.
 
(c)  Reinvested dividends will be subject only to the Deferred Sales Charge
     remaining at the time of reinvestment which may be more or less than 2.00%
     of the Public Offering Price at the time of reinvestment (see "Reinvestment
     Program").
 
(d)  The cost of preparation and printing of the Indenture, Registration
     Statement and other documents relating to the Trust, Federal and State
     registration fees and costs, initial fees of the Trustee, and legal and
     auditing expenses will be paid by the Trust and, therefore, will be borne
     by Unit Holders. Organizational expenses per Unit have been estimated based
     on a Trust with projected total assets of $25 million. To the extent the
     assets of the Trust are less than such amount, the organizational expense
     per Unit will be greater than the estimate shown.
 
(e)  Although each Trust has a term of approximately one year and is a unit
     investment trust rather than a mutual fund, this information is presented
     to permit a comparison of fees and expenses, assuming the principal amount
     and distributions are exchanged each year into a new Trust subject only to
     the Deferred Sales Charge.

                 SUMMARY OF ESSENTIAL INFORMATION--(continued)
   
    THE TRUST--The Dean Witter Select Equity Trust, Select Global Series 97-3,
Select Global 30 Portfolio 97-3 (the "Trust") is a unit investment trust
composed of publicly-traded common stocks or contracts to purchase such stocks
(the "Securities"). The objectives of the Trust are to provide income and
above-average growth potential through investment in the stocks which are the
ten common stocks in each of the DJIA, FT Index and HS Index (the "Indices" or
the "Index") having the highest dividend yield (the "Select 30") as of the Stock
Determination Dates. A hypothetical investment in approximately equal values of
the Select 30 for a period of one year would have, in 5 of the last 10 years,
yielded a higher total return than the average of the total return of the DJIA,
FT Index and HS Index for each such year. The Select Global 30 Portfolio seeks
to achieve a better performance than the average of the total return of the
three indices. Investment in a number of companies having high dividends
relative to their stock prices (possibly because their stock prices are
depressed) is designed to increase the Trust's potential for higher returns. The
Securities may appreciate or depreciate in value (or pay dividends) depending on
the full range of economic and market influences affecting corporate
profitability, the financial condition of issuers, political factors and the
prices of equity securities in general and the Securities in particular. In
addition, a decrease in the value of the British pound sterling or the Hong Kong
dollar relative to the U.S. dollar will adversely affect the U.S. dollar value
of the Trust's income and assets and, therefore, the value of Units. An
investment in Securities in the HS Index may be considered speculative and
therefore may be appropriate only for those investors able and willing to assume
the increased risks of higher price volatility, currency fluctuations and the
increased risks of investment in Hong Kong following its July 1, 1997 reversion
to Chinese control. Therefore, there is no guarantee that the objectives of the
Trust will be achieved. On the initial Date of Deposit and thereafter, the
Sponsor may, under the Indenture and Agreement, deposit additional Securities,
contracts to purchase additional Securities together with a letter of credit
and/or cash (or a letter of credit in lieu of cash) with instructions to
purchase additional Securities in order to create Additional Units while
maintaining to the extent practicable the proportionate relationship between the
number of shares of each Security in the Portfolio.
    
 
   
    TERMINATION--The Trust will terminate approximately 1 year after the initial
Date of Deposit regardless of market conditions at that time. The Trust will
then liquidate. Unit Holders of Units with a value of $500,000 or more may elect
to receive shares in-kind. Prior to termination of the Trust, the Trustee will
begin to sell the Securities held in the Trust over a period not to exceed 14
consecutive business days (the "Liquidation Period"). Monies held upon such sale
of Securities will be held uninvested in non-interest bearing accounts created
by the Indenture until distributed pro rata to Unit Holders on or about August
10, 1998 and will be of benefit to the Trustee during such period. During the
life of the Trust, Securities will not be sold to take advantage of market
fluctuations. Because the Trust is not managed and the Securities can only be
sold during the Liquidation Period or under certain other limited circumstances
described herein, the proceeds received from the sale of Securities may be less
than could be obtained if the sale had taken place at a different time.
Depending on the volume of Securities sold and the prices of and demand for
Securities at the time of such sale, the sales of Securities from the Trust may
tend to depress the market prices of such Securities and hence the value of the
Units, thus reducing termination proceeds available to Unit Holders. In order to
mitigate potential adverse price consequences of heavy volume trading in the
Securities taking place over a short period of time and to provide an average
market price for the Securities, the Trustee will follow procedures set forth in
the Indenture to sell the Securities in an orderly fashion over a period not to
exceed the Liquidation Period. The Sponsor can give no assurance, however, that
such procedures will mitigate negative price consequences or provide a better
price for such Securities. The Trust may terminate earlier than on the Mandatory
Termination Date if the value of the Trust is less than the Discretionary
Liquidation Amount set forth under "Administration of the Trust--Termination."
    
   
    DISTRIBUTION--The Trustee will distribute any dividends (net of Trust
expenses) and any proceeds from the disposition of Securities not used for
redemption of Units received by the Trust on October 15, 1997, January 15, 1998,
April 15, 1998 and on or about August 10, 1998 to holders of record on October
1, 1997, January 1, 1998, April 1, 1998 and the Termination Date, respectively.
Upon termination of the Trust, the Trustee will distribute to each Unit Holder
of record its pro rata share of the Trust's
    
 
                                       v
<PAGE>
assets, less expenses and less any Deferred Sales Charge then payable or Unit
Holders can elect to reinvest their distributions automatically in Units of a
New Series (as defined below), if offered by the Sponsor, which units will be
subject only to a deferred sales charge (see "Administration of the
Trust--Termination"). The sale of Securities in the Trust during the period
prior to termination and upon termination may result in a lower amount than
might otherwise be realized if such sale were not required at such time due to
impending or actual termination of the Trust. For this reason, among others, the
amount realized by a Unit Holder upon termination may be less than the amount
paid by such Unit Holder (see "Administration of the Trust--Distribution".)
 
    The Sponsor anticipates that, based upon the last dividends actually paid by
the companies listed in the "Schedule of Portfolio Securities," dividends from
the Securities will be sufficient to (i) pay expenses of the Trust and (ii)
after such payment, to make distributions to Unit Holders as described herein
(see "Expenses and Charges" and "Administration of the Trust-- Distribution".)
 
   
    PUBLIC OFFERING PRICE--The Public Offering Price per 100 Units is computed
on the basis of the aggregate value of the underlying Securities next computed
after receipt of a purchase order plus cash on hand in the Trust, divided by the
number of Units outstanding times 100, plus a sales charge of 2.924% of such
evaluation per 100 Units (the amount invested in Securities); this results in a
sales charge of 2.90% of the Public Offering Price. A proportionate share of
amounts, if any, in the Income Account is also added to the Public Offering
Price (see "Public Offering of Units--Public Offering Price".) The total sales
charge consists of an Initial Sales Charge and a Deferred Sales Charge, the
total of which equals 2.90% of the Public Offering Price or 2.924% of the amount
invested in Securities. The Initial Sales Charge is computed by deducting the
Deferred Sales Charge ($20.00 per 100 Units) from the aggregate sales charge;
thus, on the date of the Summary of Essential Information, the Initial Sales
Charge is $7.64 per 100 Units or 0.80% of the Public Offering Price. The Initial
Sales Charge paid by a Unit Holder may be more or less than $7.64 per 100 Units
because of the fluctuation of the value of the Securities from that on the Date
of Deposit. The Initial Sales Charge will vary with changes in the aggregate
sales charge and is deducted from the purchase price of a Unit at the time of
purchase and paid to the Sponsor. The Initial Sales Charge will be reduced on a
graduated basis on purchases of $25,000 or more. In connection with future
series of the Trust, if any, Unit Holders acquiring Units through an exchange or
rollover of units of a previous series of the Select Global 30 Portfolio will
acquire such Units subject only to the Deferred Sales Charge. The Deferred Sales
Charge is paid through reduction of Trust assets by $2.00 per 100 Units monthly
on each Deferred Sales Charge Payment Date commencing on the first Deferred
Sales Charge Payment Date shown on the Summary of Essential Information through
the sale of Securities on each such date or distribution of cash available for
such payment. Units purchased pursuant to the Reinvestment Program are subject
only to deductions remaining of the Deferred Sales Charge (see "Reinvestment
Program"). If a Unit Holder exchanges, redeems or sells his Units to the Sponsor
prior to the last Deferred Sales Charge Payment Date, the Unit Holder is
obligated to pay any remaining Deferred Sales Charge.
    
 
   
    MARKET FOR UNITS--The Sponsor, though not obligated to do so, intends to
maintain a market for the Units. If such market is not maintained, a Unit Holder
will be able to dispose of his Units through redemption at prices based on the
aggregate value of the underlying Securities. (See: "Redemption".) Market
conditions may cause such prices to be greater or less than the amount paid for
Units. The Sponsor's Repurchase Price, like the Redemption Price, will reflect
the deduction from the value of the underlying Securities of any unpaid amount
of the Deferred Sales Charge. Investors should note that the Deferred Sales
Charge of $2.00 per 100 Units will be deducted from Trust assets on the last
business day of each of the ten months commencing on the first Deferred Sales
Charge Payment Date shown on the Summary of Essential Information, and to the
extent the entire Deferred Sales Charge has not been so deducted or paid at the
time of repurchase or redemption of the Units, the remainder will be deducted
from the proceeds of sale or redemption or in calculating an in-kind redemption.
    
 
    RISK FACTORS--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, including risks associated with the limited rights of holders of
common stock to receive payments from issuers of such stock; such rights are
inferior to those of creditors and holders of debt obligations or
 
                                       vi
<PAGE>
   
preferred stock. Also, holders of common stock have the right to receive
dividends only when, as and if such dividends are declared by the issuer's board
of directors. Investors should also be aware that the value of the underlying
Securities in the Portfolio may fluctuate in accordance with changes in the
value of common stocks in general. Although there are certain risks of price
volatility associated with investment in common stocks, your risk is reduced
because your capital is divided among 30 stocks from several different industry
groups.
    
   
    FOREIGN ISSUERS. The Portfolio is considered to be concentrated in
securities of non-United States issuers. Holding securities of non-United States
companies may involve investment risks that are different from those involved in
holding securities of domestic issues, including future political and economic
developments, the possible imposition of withholding taxes and exchange controls
or other foreign governmental restrictions which might adversely affect the
payment of distributions on Securities in the Portfolio. In addition, there may
be less publicly available information about a foreign issuer and foreign
issuers may not generally be subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to domestic issuers. Foreign securities markets, while growing in
volume, have, for the most part, substantially less volume than U.S. markets,
and securities of many foreign companies are less liquid and their prices more
volatile than securities of comparable domestic companies. Brokerage commissions
and other transaction costs on foreign securities exchanges are generally higher
than in the United States and there is generally less government supervision and
regulation of exchanges, brokers and issuers in foreign countries than there is
in the United States. Global and regional perceptions of the United Kingdom and
Hong Kong markets' and currency exchange rate fluctuations should also be
considered both of which may adversely affect the value of the Foreign
Securities.
    
 
   
    HONG KONG'S REVERSION TO CHINESE SOVEREIGNTY. An investment in securities in
the HS Index may be considered speculative and therefore may be appropriate only
for those investors able and willing to assume the increased risks of higher
price volatility, currency fluctuations and the increased risks of investment in
Hong Kong following its July 1, 1997 reversion to Chinese control. In December
1984, Great Britain and China signed an agreement under which Hong Kong will
revert to Chinese sovereignty effective July 1, 1997. Hong Kong's new
constitution will be the Basic Law (promulgated by China in 1990), which will
take effect upon the resumption of Chinese sovereignty. The Basic Law will bind
executive, legislative and judicial branches of the government and provide a
framework in which the present legal system can continue.
    
 
   
    The Basic Law made clear that for the next fifty years, Hong Kong would
retain a "high degree of autonomy," except in defense and foreign affairs. While
China has committed to preserve for fifty years the capitalist economy, legal
system, and social freedoms currently enjoyed in Hong Kong, there can be no
assurance that China will abide by its commitment. The implementation of the
Basic Law is subject to China's interpretation and no assurance can be given as
to the effect of the resumption of Chinese sovereignty on Hong Kong or the Hong
Kong stock market. Hong Kong has been sensitive to political events. A difficult
transition of Hong Kong's political system could adversely effect the Hong Kong
economy and therefore the value of the Portfolio.
    
 
   
    Political disagreements have already arisen over certain aspects of the
transition from British to Chinese sovereignty over Hong Kong. Statements and
actions by various parties involved in the transition to Chinese sovereignty,
including statements relating to the scope of the Bill of Rights and other
political rights, may damage public confidence in the securities markets,
increase market volatility and may adversely affect the Trust.
    
   
    CURRENCY EXCHANGE. All of the Securities from the FT Index in the Portfolio
are quoted in British pounds sterling and all of the Securities from the HS
Index in the Portfolio are quoted in Hong Kong dollars. In the past both of
these currencies have fluctuated in value against the United States dollar for
many reasons, including supply and demand of each currency, the impact of
interest rate differentials between different currencies on the movement of
foreign currency rates, the soundness of the world economy, the rate of
inflation in the United Kingdom and Hong Kong compared to that of the United
States and the strength of the economies of the United Kingdom and Hong Kong as
compared to the economy of the United States. However, the Hong Kong Dollar has
been
    
 
                                      vii
<PAGE>
   
"pegged" to the U.S. dollar since 1983 (although there is no assurance that this
will continue in the future) and this has reduced its currency exchange risk to
some degree. (See "Risk Factors--Foreign Exchange Rates".) There can be no
assurance that fluctuations in exchange rates will not adversely affect the
value of the Units of the Trust.
    
   
    The Securities in the Indices are listed on a securities exchange. Whether
or not those Securities are, or continue to be, listed, their principal trading
market may be in the over-the-counter market. As a result, the existence of a
liquid trading market for the Securities may depend on whether dealers will make
a market in the Securities. There can be no assurance that a market will be made
for any of the Securities, that any market for the Securities will be maintained
or of the liquidity of the Securities in any markets made. In addition, the
Trust may be restricted under the Investment Company Act of 1940 from selling
Securities to the Sponsor. The price at which the Securities may be sold to meet
redemptions and the value of Units will be adversely affected if trading markets
for the Securities are limited or absent. (See "Risk Factors--Liquidity".)
    
 
    In connection with the deposit by the Sponsor of cash (or a letter of credit
in lieu of cash) with instructions to purchase additional Securities in order to
create Additional Units, to the extent that the price of a Security fluctuates
between the time the cash is deposited and the time the cash is used to purchase
the Security, Units (including previously issued Units) may represent more or
less of that Security and more or less of other Securities in the Portfolio of
the Trust. In addition, the brokerage fees incurred in purchasing Securities
with such deposited cash will be borne by the Trust. Any Unit Holder who
purchased Units prior to the purchase of Securities with such deposited cash
would experience dilution as a result of any such brokerage fees.
 
    SPECIAL CHARACTERISTICS OF THE TRUST
   
    --SECURITIES SELECTION. The Trust Portfolio consists of the ten common
stocks in each Index having the highest dividend yield as of the Stock
Determination Dates. The yield for each stock in the DJIA was calculated by
annualizing the last quarterly ordinary dividend declared and dividing the
annualized dividend by the market value of the stock. The yield for each stock
in the FT Index and the HS Index was calculated by adding together the most
recent interim and final dividend declared (generally, United Kingdom and Hong
Kong companies pay one interim and one final dividend per fiscal year) and
dividing the result by the market value of the stock. Such formula (an objective
determination) served as the basis for the Sponsor's selection of the ten stocks
in each Index having the highest dividend yield. The philosophy is simple. The
Trust does not require sophisticated analysis or an explanation of complex
investment strategies, just the pure and simple concept of buying a quality
portfolio of stocks in one convenient purchase. The Securities were selected
irrespective of any buy or sell recommendation by the Sponsor.
    
 
   
    Investors should note that the above criteria were applied to the Securities
selected for inclusion in the Trust Portfolio as of the respective Stock
Determination Dates. Subsequent to such dates, the Securities may no longer rank
among the ten stocks in each Index having the highest dividend yield, the yields
on the Securities in the portfolio may change or the Securities may no longer be
included in an Index. However, the Sponsor may, on and subsequent to the Date of
Deposit, deposit additional Securities which reflect the Portfolio as of the
Date of Deposit, subject to permitted adjustments, and sell such additional
Units created. The sale of additional Units and the sale of Units in the
secondary market may continue even though the Securities would no longer be
chosen for deposit into the Trust if the selection process were to be made at
such later time.
    
 
   
    Simple strategies can sometimes be the most effective. To outperform the
market is more difficult than just outperforming other asset classes. The Trust
seeks a higher total return than the average of the total returns of the three
Indices by acquiring the Securities, and holding them for about one year.
Purchasing a portfolio of these stocks through an investment in the Trust as
opposed to one or two individual stocks may achieve better overall performance
and will achieve greater diversification. There is only one investment decision
instead of thirty, and four distributions to the investor during the one-year
life of the Trust instead of multiple distributions. An investment in the Trust
can be cost-efficient, avoiding the odd-lot costs of buying small quantities of
    
 
                                      viii
<PAGE>
securities directly. Investment in a number of companies with high dividends
relative to their stock prices is designed to increase the Trust's potential for
higher returns. The Trust's return may consist of a combination of capital
appreciation and current dividend income.
   
THE DOW JONES INDUSTRIAL AVERAGE
    
 
   
    The first DJIA, consisting of 12 stocks, was published in THE WALL STREET
JOURNAL in 1896. The list grew to 20 stocks in 1916 and to 30 stocks on October
1, 1928. Taking into account a number of name changes, 1 of the original
companies is still in the DJIA today. For two periods of 17 consecutive years
each, there were no changes to the list: March 15, 1939-July 2, 1956 and June 2,
1959-August 8, 1976. The following is a list of the companies which currently
comprise the DJIA.

    The Dow Jones Industrial Average is comprised of 30 common stocks chosen by
the editors of THE WALL STREET JOURNAL as representative of the broad market and
of American industry. The companies are major factors in their industries and
their stocks are widely held by individuals and institutional investors.
 
    Changes in the components are made entirely by the editors of THE WALL
STREET JOURNAL without consultation with the companies, the stock exchange or
any official agency. For the sake of continuity, such changes are made rarely.
Most substitutions have been the result of mergers, but from time to time
changes may be made to achieve a better representation. The composition of the
Dow Jones Industrial Average may be changed at any time for any reason.
 
THE FINANCIAL TIMES ORDINARY SHARE INDEX
   
    The FT Index was designed to reflect changes in the United Kingdom equity
market as reflected in prices of the leading and most actively traded shares and
comprises 30 common stocks chosen by the editors of THE FINANCIAL TIMES (London)
as representative of British industry and commerce. Such companies are major
factors in their industries and their stocks are widely held by individuals and
institutional investors. The FT Index is a geometric, unweighted average of the
share prices of these companies and is calculated on a minute-by-minute basis.
Its base is 100 as of July 1, 1935. Changes in the components of the FT Index
are made entirely by the editors of THE FINANCIAL TIMES without consultation
with the companies, any stock exchange or any official agency. Since the
introduction of the Financial Times Index in 1935, there has been a steady shift
of emphasis in its makeup from heavy industry towards companies engaged in

THE HANG SENG INDEX
   
    The HS Index, which was first published in 1969, comprises 33 of the stocks
listed on the Stock Exchange of Hong Kong Ltd. (the "Hong Kong Exchange"), and
includes companies intended to represent four major market sectors: commerce and
industry, finance, properties and utilities. The HS Index is a recognized
indicator of stock market performance in Hong Kong. It is computed by dividing
the aggregate current market value of the constituent stocks (I.E. the sum of
the products of the current market price of each stock and the number of issued
shares of such stock) by the aggregate base market value of those stocks.
Accordingly, the Hang Seng Index is strongly influenced by stocks with large
market capitalizations. The HS Index represents approximately 70% of the total
market capitalization of the stocks listed on the Hong Kong Exchange. Any
changes in the components in the HS Index announced after the Foreign Stock
Determination Date will not cause a change in the identity of the common stocks
included in the Portfolio, including any Securities deposited thereafter.

(2) The change in value (the difference between the beginning and ending value
    of the Index divided by the value of the Index at the beginning of the year)
    plus the dividend return for the year (the total dividends earned during the
    year by the stocks in the Index divided by the value of the Index at the

(3) Calculated based on U.S. dollars and reflects currency exchange rate
    fluctuation. Conversion into U.S. dollars was made based on the exchange
    rate as of the last day of each year as supplied by a major international
    bank. Past exchange rate fluctuations are not indicative of future exchange
    rate movements. No adjustments have been made to reflect taxes payable or
    withholding taxes.
    
   
(4) The Average of Total Returns for the individual years are calculated by
    using a simple arithmetic average of the three indices for each year. There
    is no published index combining the total returns of the three indices. It
    is not representative of any recognized index and is purely hypothetical.

    The returns shown above reflect past performance and are not guarantees of
future performance and should not be used as a predictor of returns to be
expected in connection with a Trust. Such returns do not reflect sales charges,
commissions, expenses or taxes. Reasonable assumptions were relied upon where
data was either unavailable or only partially available and these assumptions
could have a material impact on the historical performance calculations. The
actual returns of a particular Trust or purchase of Units of a Trust will vary
from the hypothetical strategy returns due to, among other things, timing
differences and the fact that an actual Trust has sales charges, expenses and
commissions.
    
- ------------------------
   
(1) The percentage change in value, over a one year period, of a hypothetical
    investment in approximately equal values (the difference between the
    beginning and ending value of the 10 Highest Yielding Stocks in the Index
    divided by the value of the 10 Highest Yielding Stocks in the Index at the
    beginning of the year ("Select 10 Strategy Stocks")) plus the dividend
    return for the year (the total dividends earned during the year by such 10
    stocks divided by the value of such 10 stocks at the beginning of the year).
    These returns do not reflect the performance of any actual trust.
    
   
(2) Calculated based on U.S. dollars and reflects currency exchange rate
    fluctuation. Conversion into U.S. dollars in the case of the Foreign
    Securities was made based on the exchange rate as of the last day of each
    year as supplied by a major international bank. Past exchange rate
    fluctuations are not indicative of future exchange rate movements. No
    adjustments have been made to reflect taxes payable or withholding taxes.
    
   
(3) The hypothetical performance of the Select 30 strategy, which is derived by
    averaging the Total Return in U.S. dollars of the Select 10 Strategy Stocks
    in each of the DJIA, FT Index and HS Index.

    The Select Global 30 Portfolio seeks to achieve a better performance than
the average of the total return of the three Indices through investment for
about one year in 30 common stocks, ten from each Index (the ten common stocks
in such Index having the highest dividend yield as of the respective Stock
Determination Dates). In 5 of the last 10 years, a hypothetical strategy of
investing in approximately equal values of Select 30 strategy stocks each year
would have yielded a higher total return than the Average of Total Returns.
    
 
   
    The average annual return reflects a rate of growth per year (assuming
reinvestment of all dividends at the end of each period) that a hypothetical
investment in all of the stocks in each Index and the Select Global 30 strategy
would have provided over the above 10 year period. The returns shown above are
not guarantees of future performance and should not be used as a predictor of
returns to be expected in connection with the Portfolio. Such returns do not
reflect sales charges, commissions, expenses or taxes. As indicated in the above
tables, the Select Global 30 strategy underperformed the total returns of the
Indices and the Average of Total Returns in certain years and there can be no
assurance that the portfolio of the Trust will outperform the total returns of
the Indices and the Average of Total Returns over the life of the Trust. The
actual returns of a particular Trust or purchase of Units of a Trust will vary
from the hypothetical strategy returns due to, among other things, timing
differences, and the fact that an actual Trust has sales charges, expenses, and
commissions. In addition, a Security may have a weighting in an Index which is
different than such Security's weighting in the Portfolio.

    PERFORMANCE INFORMATION--Information on the performance of the Trust, one or
more Select Global 30 series and the Select Global 30 stock strategy on the
basis of changes in Unit price (total return) may be included from time to time
in advertisements, sales literature and reports to current or prospective Unit
Holders. Average annualized returns may also be shown for consecutive series of
the same Select Global 30 Portfolio cycle. Information on the performance of the
Select 30 stocks contained in this Prospectus, as further updated, may also be
included from time to time in such material. Performance of individual Select
Global 30 Portfolios may also be shown along with performance of the other
Select Global 30 Portfolios for comparable (though not necessarily identical)
periods and on a combined basis. Total return is computed by dividing share
price changes plus dividends reinvested at the end of each year by initial share
prices, but does not reflect commissions, taxes or Portfolio sales charges or
expenses, which would decrease the return. Average annualized return figures of
a Portfolio would reflect deduction of the maximum sales charge. Material
reflecting annual performance of a hypothetical investment in the Select Global
30 stock strategy does not reflect commissions, taxes, sales charges or
expenses. No provision is made for any income taxes payable or withholding
taxes. Past performance cannot guarantee future results.

    We have audited the accompanying statement of financial condition and
schedule of portfolio securities of the Dean Witter Select Equity Trust Select
Global Series 97-3 Select Global 30 Portfolio 97-3 as of April 30, 1997. These
financial statements are the responsibility of the Trustee. (See note (f) to the
Statement of Financial Condition). Our responsibility is to express an opinion
on these financial statements based on our audit.
    
 
   
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of an irrevocable letter of credit and contracts for the purchase
of securities, as shown in the statement of financial condition and schedule of
portfolio securities as of April 30, 1997, by correspondence with The Bank of
New York, the Trustee. An audit also includes assessing the accounting
principles used and significant estimates made by the Trustee, as well as
evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.
    
 
   
    In our opinion, the statement of financial condition and schedule of
portfolio securities referred to above present fairly, in all material respects,
the financial position of the Dean Witter Select Equity Trust Select Global
Series 97-3 Select Global 30 Portfolio 97-3 as of April 30, 1997 in conformity

- ------------------------
(a)  The aggregate U.S. dollar value of the Securities represented by Contracts
     to Purchase listed under "Schedule of Portfolio Securities" based on the
     U.S. dollar offer side value of the relevant exchange rate determined by
     the Trustee at the Evaluation Time on April 30, 1997 and their cost to the
     Trust are the same. The value is determined by the Trustee on the basis set
     forth under "Public Offering of Units--Public Offering Price" as of the
     Date of Deposit. An irrevocable letter of credit drawn on Banque Paribas
     New York Branch in the amount of $300,000 has been deposited with the
     Trustee.
 
(b)  Organizational costs borne by the Trust have been deferred and will be
     amortized over the life of the Trust. Organizational costs have been
     estimated based on a Trust with projected total assets of $25 million. To
     the extent the assets of the Trust are less than $25 million, the
     organizational costs may be less although the per Unit amount may increase.
     To the extent the assets of the Trust are more, the organizational costs
     may be higher.
 
(c)  Represents the aggregate amount of mandatory distributions of $2.00 per 100
     Units per month payable on the last business day of each month from July
     31, 1997 through April 30, 1998. Distributions will be made to an account
     maintained by the Trustee from which the Unit Holders' Deferred Sales
     Charge obligation to the Sponsor will be satisfied. If Units are redeemed
     prior to April 30, 1998, the remaining portion of the distribution
     applicable to such Units will be transferred to such account on the
     redemption date.
 
(d)  The aggregate Public Offering Price is computed on the basis set forth
     under "Public Offering of Units--Public Offering Price" as of the
     evaluation time on the Date of Deposit.
 
(e)  The aggregate sales charge of 2.90% of the Public Offering Price per 100
     Units is computed on the basis set forth under "Public Offering of
     Units--Public Offering Price".
 
(f)  The Trustee has custody of and responsibility for all accounting and
     financial books, records, financial statements and related data of the
     Trust and is responsible for establishing and maintaining a system of
     internal controls directly related to, and designed to provide reasonable
     assurance as to the integrity and reliability of, financial reporting of
     the Trust. The Trustee is also responsible for all estimates and accruals
     reflected in the Trust's financial statements. The Trustee determines the
     price for each underlying Security included in the Trust's Schedule of
     Portfolio Securities on the basis set forth in "Public Offering of
     Units--Public Offering Price". Under the Securities Act of 1933, as amended
     (the "Act"), the Sponsor is deemed to be an issuer of the Trust's Units. As
     such, the Sponsor has the responsibility of an issuer under the Act with
     respect to financial statements of the Trust included in the Registration
     Statement under the Act and amendments thereto.

(1)  Based on the latest quarterly or semiannual declaration in the case of
     stocks in the DJIA and the most recent interim and final dividends declared

     exchange converted into U.S. dollars at the offer side of the exchange rate
     at the Evaluation Time on April 30, 1997. The aggregate purchase price to
     the Sponsor for the Securities deposited in the Trust is $237,182.87.

THE SELECT EQUITY TRUSTS
       Achieving financial success in today's dynamic markets depends on
       selecting the right investment strategy. As new opportunities emerge,
       sparked by changing business trends, market strategies must be geared to
       capitalize on them. Because such opportunities may not be easily
       identified by individual investors, Dean Witter has developed the Select
       Equity Trusts which offer investors a simple and convenient way to
       participate in the equity market.
- --------------------------------------------------------------------------------
PORTFOLIO SELECTION
   
       The Select Global 30 Portfolio consists of the 10 common stocks in each
       of the Dow Jones Industrial Average, Financial Times Index and Hang Seng
       Index having the highest dividend yield as of the Stock Determination
       Dates. The Trust is specifically designed for investors seeking income
       and above-average growth potential. Because the Trust is a fixed
       portfolio of preselected securities, purchasers know in advance what they
       are investing in.
    
- --------------------------------------------------------------------------------
RISK FACTORS--SPECIAL CONSIDERATIONS
   
       The risks of an investment in Units of the Trust include price volatility
       resulting from factors affecting the common stock of the issuer of a
       portfolio security in particular and the equity markets in general. The
       political and economic risks associated with an investment in stocks
       issued by United Kingdom and Hong Kong issuers and the risk of
       unfavorable exchange rates for the Foreign Securities are present.
    
- --------------------------------------------------------------------------------
DIVERSIFICATION
   
       The Trust helps reduce risk because it allows Unit holders to participate
       in a more diversified portfolio of stocks in contrast to buying an
       individual stock. Although there are certain risks associated with
       investment in common stocks, the Trust helps reduce risk because an
       investment is divided among 30 stocks from various industry groups and
       geographic areas. It would be difficult for the average investor to
       achieve a comparable level of diversification, without making a
       substantial capital commitment or incurring odd-lot charges.
    
- --------------------------------------------------------------------------------
REINVESTMENT OPTION
       Investors may elect to have distributions automatically reinvested in
       additional units of the Trust subject to the then remaining deferred
       sales charge.
- --------------------------------------------------------------------------------
NO TURNOVER
   
       The Select Global 30 Portfolio is a portfolio of 30 specified stocks.
       Listed within this prospectus are the stocks that make up the portfolio;
       under ordinary circumstances the issuers of the stocks in the portfolio
       will not change. Managed investment portfolios may have very high
       turnover rates over a one-year period. The Trust typically has no
       turnover during its life.
    
 
    The Offering Features are a part of the prospectus and should be read in
                                  conjunction
                          with the entire prospectus.
<PAGE>
- ---------------------------------------------------
FLEXIBILITY THROUGH EXCHANGE PRIVILEGES
 
       Investors may elect, at any time, to exchange or rollover these units for
       units of another Dean Witter Select Trust at a sales charge less than the
       sales charge that a new investor would pay.
- --------------------------------------------------------------------------------
SHORT-TERM LIFE
 
   
       The Trust will terminate in approximately one year at which time the
       Portfolio will liquidate. Investors owning units with a value in excess
       of $500,000 may elect to receive distributions in respect of their Units
       in kind. Investors not so electing will receive cash. Investors may, of
       course, sell or redeem Units prior to the Trust's termination.
    
- --------------------------------------------------------------------------------
EASY LIQUIDITY
 
   
       Although not obligated to do so, Dean Witter intends to maintain a
       secondary market for the Units. All or a portion of your Units may be
       liquidated at any time, without a sales charge other than any deferred
       sales charge then payable. The price you receive will reflect market
       conditions and then current exchange rates and could be more or less than
       the price originally paid.
    
- --------------------------------------------------------------------------------
RETIREMENT ACCOUNTS
 
       This Trust may be an attractive investment vehicle for a self-directed
       IRA or self-directed self-employed retirement plan ("Keogh plan"). As an
       income- and growth-oriented investment, it may be a suitable complement
       to help achieve overall portfolio diversification.
- --------------------------------------------------------------------------------
NO MARKET TIMING
   
       The Select Global 30 Portfolio leaves "emotional trading" behind by
       focusing and buying a quality portfolio of blue-chip stocks with high
       dividend yields. Due to the Trust's "buy and hold" strategy, an
       investor's money is generally invested at all times. Managed investment
       vehicles buy and sell securities and may have a sizable percentage of
       assets in cash.
    
 
    The Offering Features are a part of the prospectus and should be read in
                                  conjunction

                               PROSPECTUS PART B
                        DEAN WITTER SELECT EQUITY TRUST
 
                                  INTRODUCTION
 
    This series of the Dean Witter Select Equity Trust (the "Trust") was created
under the laws of the State of New York pursuant to a Trust Indenture and
Agreement (the "Indenture") and a related Reference Trust Agreement (the
"Agreement") (collectively, the "Indenture and Agreement")*, between Dean Witter
Reynolds Inc. (the "Sponsor") and The Bank of New York (the "Trustee"). The
Sponsor is a principal operating subsidiary of Dean Witter, Discover & Co.
("DWDC"), a publicly-held corporation. (See: "Sponsor".) The objectives of the
Trust are income and above average growth potential through investment in a
fixed portfolio of Securities (the "Portfolio") of publicly-traded common stock.
There is no assurance that these objectives will be met because the Securities
may appreciate or depreciate in value (or pay dividends) depending on the full
range of economic and market influences affecting corporate profitability, the
financial condition of issuers and the prices of equity securities in general
and the Securities in particular, fluctuations in exchange rates, political and
economic uncertainty, foreign security volatility and other factors.
 
   
    On the date of creation of the Trust (the "Date of Deposit"), the Sponsor
deposited with the Trustee certain securities and/or contracts and funds
(represented by irrevocable letter(s) of credit issued by major commercial
bank(s)) for the purchase of such securities (collectively, the "Securities") at
prices equal to the market value of such Securities converted into U.S. dollars
in the case of Foreign Securities at the offer side value of the applicable
exchange rate as determined by the Trustee as of the Date of Deposit and/or cash
(or a letter of credit in lieu of cash) with instructions to the Trustee to
purchase such Securities. (See: "Schedule of Portfolio Securities".) The Trust
was created simultaneously with the deposit of the Securities with the Trustee
and the execution of the Indenture and the Agreement. The Trustee then
immediately recorded the Sponsor as owner of the units (the "Units") comprising
the entire ownership of the Trust. Through this prospectus (the "Prospectus"),
the Sponsor is offering the Units, including Additional Units, as defined below,
for sale to the public. The holders of Units (the "Unit Holders") will have the
right to have their Units redeemed at a U.S. dollar price based on the market
value of the Securities (the "Redemption Value") if they cannot be sold in the
secondary market which the Sponsor, although not obligated to, proposes to
maintain. In addition, the Sponsor may offer for sale, through this Prospectus,
Units which the Sponsor may have repurchased in the secondary market or upon the
tender of such Units for redemption. The Trustee has not participated in the
selection of Securities for the Trust, and neither the Sponsor nor the Trustee
will be liable in any way for any default, failure or defect in any Securities.
    
 
    With the deposit of the Securities in the Trust on the Date of Deposit, the
Sponsor established a proportionate relationship between the number of shares of
each Security in the Portfolio. (The original proportionate relationships on the
Date of Deposit are set forth in "Schedule of Portfolio Securities".) The
original proportionate relationships are subject to adjustment under certain
limited circumstances. (See: "Administration of the Trust--Portfolio
Supervision".) The Sponsor is permitted under the Indenture and Agreement to
deposit additional Securities, contracts to purchase additional Securities
together with a letter of credit and/or cash (or a letter of credit in lieu of
cash) with instructions to the Trustee to purchase additional Securities in
order to create additional Units ("Additional Units"). Any such additional
deposits made in the 90 day period following the creation of the Trust will
consist of securities identical to those already in the Trust and will be in
amounts which maintain, to the extent practicable, the original proportionate
relationship between the number of shares of each Security and any cash in the
Portfolio. It may not be possible to maintain the exact original proportionate
relationship because of price changes or other reasons. Any cash deposited with
instructions to purchase Securities may be held in an interest bearing account
by the Trustee. Any interest earned on such cash will be the property of the
Trust. Any cash deposited with instruction to purchase Securities not used to
purchase Securities and any

* Reference is hereby made to said Indenture and Agreement and any statements
  contained herein are qualified in their entirety by the provisions of said
  Indenture and Agreement.
<PAGE>
interest not used to pay Trust expenses will be distributed to Unit Holders on
the earlier of the first Distribution Date or 90 days after the Date of Deposit.
Additional Units may be continuously offered for sale to the public by means of
this Prospectus. Subsequent to the 90 day period following the Date of Deposit
any deposit of additional Securities and cash must exactly replicate the
portfolio immediately prior to such deposit. The Sponsor may acquire large
volumes of additional Securities for deposit into the Trust over a short period
of time. Such acquisitions may tend to raise the market prices of these
Securities. To minimize the risk of price fluctuations when purchasing
Securities, the Trust may purchase Securities at the closing price as of the
Evaluation Time by entering into trades with unaffiliated broker/dealers for the
purchase of large quantities of shares. Such trades will be entered into at an
increased commission cost which will be borne by the Trust (see "Summary of
Essential Information"). The Sponsor cannot currently predict the actual market
impact of the Sponsor's purchases of additional Securities, because the actual
volume of Securities to be purchased and the supply and price of such Securities
is not known.
 
    Units will be sold to investors at the Public Offering Price next computed
after receipt of the investor's order to purchase Units, if Units are available
to fill orders on the day that that price is set. If Units are not available or
are insufficient to fill the order, the investor's order will be rejected by the
Sponsor. The number of Units available may be insufficient to meet demand
because of the Sponsor's inability to or decision not to purchase and deposit
underlying Securities in amounts sufficient to maintain the proportionate
numbers of shares of each Security as required to create additional Units. The
Sponsor may, if unable to accept orders on any given day, offer to execute the
order as soon as sufficient Units can be created. An investor who agrees to this
will be deemed to place a new order for that number of Units each day until that
order is accepted. The investor's order will then be executed, when Units are
available, at the Public Offering Price next calculated after such continuing
order is accepted. The investor will, of course, be able to revoke his purchase
offer at any time prior to acceptance by the Sponsor. The Sponsor will execute
orders to purchase in the order it determines that they are received, i.e.,
orders received first will be filled first, except that indications of interest
prior to the effectiveness of the registration of the offering of Trust Units
which become orders upon effectiveness will be accepted according to the order
in which the indications of interest were received.
 
   
    On the Date of Deposit, each Unit represented the fractional undivided
interest in the Securities and net income of the Trust set forth under "Summary
of Essential Information." Thereafter, if any Units are redeemed, the amount of
Securities in the Trust will be reduced, and the fractional undivided interest
represented by each remaining Unit in the balance of the Trust will be
increased. However, if Additional Units are issued by the Trust, the aggregate
value of the Securities in the Trust will be increased by amounts allocable to
such Additional Units and the fractional undivided interest in the balance will
be decreased. In connection with the deposit by the Sponsor of cash (or a letter
of credit in lieu of cash) with instructions to purchase additional Securities
in order to create Additional Units, to the extent that the price of a Security
fluctuates or exchange rates fluctuate between the time the cash is deposited
and the time the cash is used to purchase the Security, Units (including
previously issued Units) may represent more or less of that Security and more or
less of other Securities in the Portfolio of the Trust. Units will remain
outstanding until redeemed upon tender to the Trustee by any Unit Holder (which
may include the Sponsor) or until the termination of the Trust pursuant to the
Indenture and Agreement.
    
 
                                   THE TRUST
 
RISK FACTORS--SPECIAL CONSIDERATIONS
 
   
    An investment in Units of the Trust should be made with an understanding of
the risks which an investment in publicly-traded common stock including foreign
common stocks may entail, including the risk that the value of the Portfolio and
hence of the Units will decline with decreases in the market value of the
Securities. The Trust will be terminated and liquidated no later than the
Mandatory Termination Date set forth in the "Summary of Essential Information."
    
 
                                       2
<PAGE>
    On each Deferred Sales Charge Payment Date Securities will be sold pro rata
in an amount equal to $2.00 per 100 Units to pay the Deferred Sales Charge and
the proceeds will be distributed to the Sponsor. As Securities are sold to pay
the Deferred Sales Charge a Unit Holder's assets will be reduced and income per
Unit may be reduced.
 
SUMMARY DESCRIPTION OF THE PORTFOLIO
 
    As used herein, the term "Common Stocks" refers to the common stocks (or
contracts to purchase such common stocks) (any such contracts to purchase common
stocks to be accompanied by an irrevocable letter of credit sufficient to
perform such contracts), initially deposited in the Trust and described under
"Schedule of Portfolio Securities". The term "Securities" includes any
additional common stock or contracts to purchase additional common stock
together with the corresponding irrevocable letter of credit, subsequently
acquired by the Trust pursuant to the Indenture and Agreement.
 
    An investment in Units of the Trust should be made with an understanding
that the value of the underlying Securities, and therefore the value of Units,
will fluctuate, depending upon the full range of economic and market influences
which may affect the market value of such Securities. Certain risks are inherent
in an investment in equity securities, including the risk that the financial
condition of one or more of the issuers of the Securities may worsen or the
general condition of the common stock market may weaken. In such case, the value
of the Portfolio Securities and hence the value of Units may decline. Common
stocks are susceptible to general stock market movements and to volatile and
unpredictable increases and decreases in value as market confidence in and
perceptions of the issuers change from time to time. Such perceptions are based
upon varying reactions to such factors as expectations regarding domestic and
foreign economic, monetary and fiscal policies, inflation and interest rates,
currency exchange rates, economic expansion or contraction, and global or
regional political, economic or banking crises. In addition, investors should
understand that there are certain payment risks involved in owning common
stocks, including risks arising from the fact that holders of common and
preferred stocks have rights to receive payments from the issuers of those
stocks that are generally inferior to those of creditors of, or holders of debt
obligations issued by, such issuers. Furthermore, the rights of holders of
common stocks are inferior to the rights of holders of preferred stocks. Holders
of common stocks of the type held in the Portfolio have a right to receive
dividends only when, as 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 on 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 ordinarily participate in
other amounts available for distribution by the issuing corporation. Cumulative
preferred stock dividends must be paid before common stock dividends, and any
cumulative preferred stock dividend omitted is added to future dividends payable
to the holders of such cumulative preferred stock. Preferred stocks are also
entitled to rights on liquidation which are senior to those of common stocks.
For these reasons, preferred stocks entail less risk than common stocks.
However, neither preferred nor common stocks represent an obligation or
liability of the issuer and therefore do not offer any assurance of income or
provide the degree of protection of capital of debt securities.
 
   
    The issuance of debt securities (as compared with both preferred and common
stock) and preferred stock (as compared with common stock) will create prior
claims for payment of principal and interest (in the case of debt securities)
and dividends and liquidation preferences (in the case of preferred stock) 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. Further, unlike
debt securities which typically have a stated principal amount payable at
maturity (which value will be subject to market fluctuations prior thereto), or
preferred stocks which typically have a liquidation preference and which may
have stated optional or mandatory redemption provisions, common stocks have
neither a fixed principal amount nor a maturity date and have values which are
subject to market fluctuations for as long as the common stocks remain
outstanding. Additionally, market timing and volume trading will also affect the
underlying value of Securities, including the Sponsor's buying of additional
Securities and the Trust's selling of Securities during the Liquidation Period.
The value of the Securities in the Portfolio thus may be expected to fluctuate
over the entire life of the Trust to values higher or lower than those
prevailing on the Date of
    
 
                                       3
<PAGE>
Deposit. The Sponsor may direct the Trustee to dispose of Securities under
certain specified circumstances (see "Administration of the Trust--Portfolio
Supervision"). However, Securities will not be disposed of solely as a result of
normal fluctuations in market value.
 
    There can be no assurance that a market will be made for any of the
Securities, that any market for the Securities will be maintained or of the
liquidity of the Securities in any markets made. In addition, the Trust may be
restricted under the Investment Company Act of 1940 from selling Securities to
the Sponsor. The price at which the Securities may be sold to meet redemptions
and the value of the Trust will be adversely affected if trading markets for the
Securities are limited or absent.
   
    FOREIGN ISSUERS. Investment in a Portfolio in which the majority of the
securities are securities of foreign issuers involves investments risks that are
different in some respects from an investment in a trust that invests in
securities of domestic issuers. Those investment risks include future political
and economic developments and the possible establishment of exchange controls or
other governmental restrictions which might adversely affect the payment or
receipt of payment of dividends on the relevant Securities. In addition, for the
foreign issuers that are not subject to the reporting requirements of the
Securities Exchange Act of 1934, there may be less publicly available
information than is available from a domestic issuer. Also, foreign issuers are
not necessarily subject to uniform accounting, auditing and financial reporting
standards, practices and requirements such as those applicable to domestic
issuers.
    
 
    Securities issued by non-U.S. issuers generally pay dividends in foreign
currencies, and are principally traded in foreign currencies. Therefore, there
is a risk that the United States dollar value of these Securities will vary with
fluctuations in the United States dollar foreign exchange rates for the relevant
currencies.
 
    FOREIGN EXCHANGE RATES. A Portfolio of securities that are principally
traded in foreign currencies involves investment risks that are substantially
different from an investment in a trust which invests in securities that are
principally traded in United States dollars. This is because the United States
dollar value of a Portfolio (and hence of the Units) and of the distributions
from the Portfolio will vary with fluctuations in the United States dollar
foreign exchange rates for the relevant currencies. Most foreign currencies have
fluctuated widely in value against the United States dollar for many reasons,
including supply and demand of the respective currency, the soundness of the
world economy and the strength of the respective economy as compared to the
economies of the United States and other countries.
 
   
    The post-World War II international monetary system was, until 1973,
dominated by the Bretton Woods Treaty, which established a system of fixed
exchange rates and the convertibility of the United States dollar into gold
through foreign central banks. Starting in 1971, growing volatility in the
foreign exchange markets caused the United States to abandon gold convertibility
and to effect a small devaluation of the United States dollar. In 1973, the
system of fixed exchange rates between a number of the most important industrial
countries of the world, among them the United States and most Western European
countries, was completely abandoned. Subsequently, major industrialized
countries have adopted "floating" exchange rates, under which daily currency
valuations depend on supply and demand in a freely fluctuating international
market. Many smaller or developing countries have continued to "peg" their
currencies to the United States dollar although there has been some interest in
recent years in "pegging" currencies to "baskets" of other currencies or to a
Special Drawing Right administered by the International Monetary Fund. Since
1983, the Hong Kong dollar has been pegged to the U.S. dollar, although there is
no assurance that this will continue in the future. In Europe a European
Currency Unit ("ECU") has been developed. Currencies are generally traded by
leading international commercial banks and institutional investors (including
corporate treasurers, money managers, pension funds and insurance companies).
From time to time, central banks in a number of countries also are major buyers
and sellers of foreign currencies, mostly for the purpose of preventing or
reducing substantial exchange rate fluctuations.
    
 
    Exchange rate fluctuations are partly dependent on a number of economic
factors including economic conditions within countries, the impact of actual and
proposed government policies on the value of the currencies, interest rate
differentials between
 
                                       4
<PAGE>
the currencies, the balance of imports and exports of goods and services and
transfers of income and capital from one country to another. These economic
factors are influenced primarily by a particular country's monetary and fiscal
policies (although the perceived political situation in a particular country may
have an influence as well--particularly with respect to transfers of capital).
Investor psychology may also be an important determinant of currency
fluctuations in the short run. Moreover, institutional investors trying to
anticipate the future relative strength or weakness of a particular currency may
sometimes exercise considerable speculative influence on currency exchange rates
by purchasing or selling large amounts of the same currency or currencies.
However, over the long term, the currency of a country with a low rate of
inflation and a favorable balance of trade should increase in value relative to
the currency of a country with a high rate of inflation and deficits in the
balance of trade.
 
    The following table sets forth recent end-of-month United States dollar
exchange rates for the British pound sterling and the Hong Kong dollar.
Fluctuations of the rates that have occurred in the past are not necessarily
indicative of fluctuations that may occur over the life of the Trust:

    The Trustee will estimate current exchange rates for the relevant currencies
based on activity in the various currency exchange markets. However, since these
markets are volatile, depending on the activity at any particular time of the
large international commercial banks, various central banks, large multinational
corporations, speculators and other buyers and sellers of foreign currencies,
and since actual foreign currency transactions may not be instantly reported,
the exchange rates estimated by the Trustee may not be indicative of the amount
in United States dollars the Trust would receive had the Trustee sold any
particular currency in the market.
 
   
    The foreign exchange transactions of a Trust may be concluded by the Trustee
with foreign exchange dealers acting as principals either on a spot (I.E., cash)
buying basis or on a forward foreign exchange basis on the date a Trust is
entitled to receive the applicable foreign currency. These forward foreign
exchange transactions will generally be of as short a duration as practicable
and will generally settle on the date of receipt of the applicable foreign
currency involving specific receivables or payables of the Trust accruing in
connection with the purchase and sale of its Securities and income received on
the Securities or the sale and redemption of Units. These transactions are
accomplished by contracting to purchase or sell a specific currency at a future
date and price set at the time of the contract. The cost to the Trust of
engaging in these foreign currency transactions varies with such factors as the
currency involved, the length of the contract period and the market conditions
then prevailing. Since transactions in foreign currency exchange are usually
conducted on a principal basis, fees or commissions are not normally involved.
Although foreign exchange dealers trade on a net basis, they do realize a profit
based upon the difference between the price at which they are willing to buy a
particular currency (bid price) and the price at which they are willing to sell
the currency (offering price). The relevant exchange rate used for evaluations
of the Securities may include the cost of buying or selling, as the case may be,
of any forward foreign exchange contract in the relevant currency.
    
 
   
    EXCHANGE CONTROLS. On the basis of the best information available to the
Sponsor at the present time none of the Foreign Securities is subject to
exchange control restrictions under existing law which would materially
interfere with payment to the Portfolio of amounts due on the Foreign Securities
either because the particular jurisdictions have not adopted any currency
regulations of this type or because the issues qualify for an exemption or the
Portfolio, as an extraterritorial investor, has qualified its
    
 
                                       6
<PAGE>
   
purchase of the Foreign Securities as exempt by following applicable
"validation" or similar regulatory or exemptive procedures. However, there can
be no assurance that exchange control regulations might not be adopted in the
future which might adversely affect payments to a Trust.
    
 
   
    In addition, the adoption of exchange control regulations and other legal
restrictions could have an adverse impact on the marketability of international
securities in the Portfolio and on the ability of the Trust to satisfy its
obligation to redeem Units tendered to the Trustee for redemption (see
"Redemption").
    
 
   
    LIQUIDITY. Foreign securities generally have not been registered under the
Securities Act of 1933 and may not be exempt from the registration requirements
of the Act. Sales of non-exempt Securities by a Trust in United States
securities markets are subject to severe restrictions and may not be
practicable. Accordingly, sales of these Securities by a Portfolio will
generally be effected only in foreign securities markets. Although the Sponsor
does not believe that a Portfolio will encounter obstacles in disposing of the
Securities, investors should realize that the Securities may be traded in
foreign countries where the securities markets are not as developed or efficient
and may not be as liquid as those in the United States. To the extent the
liquidity of these markets becomes impaired, however, the value of a Portfolio
when responding to a substantial volume of requests for redemption of Units
(should redemptions be necessary despite the market making activities of the
Sponsor) received at or about the same time could be adversely affected. This
might occur, for example, as a result of economic or political turmoil in a
country in whose currency a Portfolio had a substantial portion of its assets
invested or should relations between the United States and such foreign country
deteriorate markedly. Even though the Securities are listed, the principal
trading market for the Securities may be in the over-the-counter market. As a
result, the existence of a liquid trading market for the Securities may depend
on whether dealers will make a market in the Securities. There can be no
assurance that a market will be made for any of the Securities, that any market
for the Securities will be maintained or of the liquidity of the Securities in
any markets made. In addition, the Trust may be restricted under the Investment
Company Act of 1940 from selling Securities to the Sponsor. The price at which
the Securities may be sold to meet redemptions and the value of a Portfolio will
be adversely affected if trading markets for the Securities are limited or
absent.
    
 
   
    The information set forth below has been extracted from various governmental
and private publications, but no representation can be made as to its accuracy;
furthermore, no representation is made that any correlation exists between the
state of the economy of the United Kingdom and the economy of Hong Kong and the
value of any Securities held by the Trust.
    
   
UNITED KINGDOM
    
 
    The Portfolio contains common stocks of United Kingdom companies engaged in
such industries as the building materials industry, the food and beverage
industry, the automotive/aviation industry, the transportation industry,
engineering, finance and utilities.
 
    The economy of the United Kingdom is focused upon the private services
sector, which includes the wholesale and retail sector, banking, finance,
insurance and tourism. Services as a whole account for a majority of the United
Kingdom's gross national product and make a significant contribution to the
country's balance of payments. London is one of the world's major financial
centers, with a substantial part of the business international in nature. The
continuance of London as an international financial center is dependent on,
among other things, a favorable regulatory regime and its success against
foreign competition. Current risks affecting the United Kingdom's economy
include over-expansion of the economy, increased taxation and a possible change
of political party controlling the government.
 
    In addition, the United Kingdom is a member of the European Union (the
"EU"). The EU was established by the Treaty on Economic Union signed at
Maastricht which came into force on November 1, 1994. The aim of the Maastricht
Treaty, as it is sometimes known, is to build on the economic and monetary
integration put in place by the Treaties establishing the European Communities
and to extend the ambit of the EU to matters such as social policy,
international relations and defense. One of the
 
                                       7
<PAGE>
   
central aims of the Maastricht Treaty is to create an internal market in the EU.
The basic legal framework to assure the free circulation of goods, services and
capital is well advanced and systematic controls at internal borders on goods,
capital and services have been abolished. The EU now consists of 15 nations,
having expanded with the accession of Sweden, Finland and Austria on January 1,
1995. The EU is a powerful trade bloc with a combined population of
approximately 350 million people and an annual gross national product of more
than $5.5 trillion. The recent rapid political and social change throughout
Europe make the extent and nature of future economic development in the United
Kingdom and Europe and the impact of such development upon the value of the
Securities in the Portfolio impossible to predict at present. Volatility in oil
prices could slow economic development throughout Western Europe; moreover, it
is not possible to accurately predict the effect of the current political and
economic situation upon the long-term inflation and balance of trade cycles and
how these changes would affect the currency exchange rate between the U.S.
dollar and the British pound sterling.
    
   
HONG KONG
    
   
    The Hong Kong Portfolio contains common stocks of companies trading on the
Hong Kong Exchange and engaged in such businesses as hotels, property and real
estate, textiles, telecommunications and utilities. Hong Kong, which was
established as a colony of Great Britain in the 1840's, is situated adjacent to
the southern coast of the People's Republic of China ("China"). It is currently
a colony of the United Kingdom and administered by the Hong Kong Government,
which is headed by a Governor appointed by the Queen on the advice of the
British government. On July 1, 1997, Britain will hand over to China control of
the colony, Hong Kong. Investors should note that this is prior to the
termination date for the Trust. An investment in Securities in the HS Index may
be considered speculative and therefore may be appropriate only for those
investors able and willing to assume the increased risks of higher price
volatility, currency fluctuations and the increased risks of investment in Hong
Kong following its July 1, 1997 reversion to Chinese control. Under British
rule, the Hong Kong government has generally followed a laissez-faire policy
towards industry. There are limited import, export or foreign exchange
restrictions, and regulation of business is generally less than in other
developed countries.
    
 
   
    HONG KONG'S REVERSION TO CHINESE SOVEREIGNTY. In December 1984, Great
Britain and China signed an agreement under which Hong Kong will revert to
Chinese sovereignty effective July 1, 1997. Hong Kong's new constitution will be
the Basic Law (promulgated by China in 1990), which will take effect upon the
resumption of Chinese sovereignty. The Basic Law will bind executive,
legislative and judicial branches of the government and provide a framework in
which the present legal system can continue.
    
 
   
    The Basic Law made clear that for the next fifty years, Hong Kong would
retain a "high degree of autonomy," except in defense and foreign affairs. While
China has committed to preserve for fifty years the capitalist economy, legal
system, and social freedoms currently enjoyed in Hong Kong, there can be no
assurance that China will abide by its commitment. The implementation of the
Basic Law is subject to China's interpretation and no assurance can be given as
to the effect of the resumption of Chinese sovereignty on Hong Kong or the Hong
Kong stock market. Hong Kong has been sensitive to political events. A difficult
transition of Hong Kong's political system could adversely effect the Hong Kong
economy and therefore the value of the Portfolio.
    
 
   
    Political disagreements have already arisen over certain aspects of the
transition from British to Chinese sovereignty over Hong Kong. Contrary to the
Basic Law, China established Hong Kong's next government. On December 11, 1996,
Tung Che Hwa was named Hong Kong's first Chinese chief executive and shortly
thereafter a hand-picked legislature was selected. Continued statements and
actions by various parties involved in the transition to Chinese sovereignty,
including statements relating to the scope of the Bill of Rights and other
political rights, may damage public confidence in the securities markets, may
increase market volatility and may adversely affect the Trust.
    
 
                                       8
<PAGE>
   
    In addition, the government of China has no procedures for the orderly
succession of its leadership. The death of Deng Xiaoping, China's paramount
leader and architect of economic modernization, has raised uncertainties about
China's political stability, economic policies, and future with Hong Kong. The
Sponsor cannot predict what effect political instability may have on the prices
of the stocks in the Trust.
    
   
Hong Kong Exchange
    
   
    Formal trading of securities was established in Hong Kong in 1891, when the
Association of Stockbrokers in Hong Kong was formed. It was renamed the Hong
Kong Stock Exchange in 1914. In 1969, the Far East exchange was formed, followed
by the Kam Ngan Stock Exchange in 1971 and the Kowloon Stock Exchange in 1972.
These four exchanges were merged to form The Stock Exchange of Hong Kong Limited
(the "Hong Kong Exchange"), which commenced trading on April 2, 1986. With a
total market capitalization as of February 29, 1996 of approximately US$345.6
billion, the Hong Kong Exchange is the second largest stock market in Asia,
measured by market capitalization, behind that of Japan. The Securities and
Futures Commission, which was established by the Hong Kong government in May
1989 in response to the difficulties encountered in Hong Kong's financial
markets at the time of the October 1987 world stock market crash, exercises
supervision of the securities, financial investment and commodities futures
industry.
    
   
Volatility of the Hang Seng Index
    
   
    Securities prices on the Hang Seng Index can be highly volatile and are
sensitive to developments in both Hong Kong and China, as well as other world
markets. For example, in 1989, the Hang Seng Index rose to 3,310 in May from its
previous year-end level of 2,687 but fell to 2,094 in early June following the
events at Tiananmen Square. The Hang Seng Index gradually climbed in subsequent
months but fell by 181 points on October 13, 1989 (approximately 6.5%) following
a substantial fall in the U.S. stock market, and at the year end, closed at a
level of 2,837. Also during 1994, the Hang Seng Index lost approximately 31% of
its value. There can be no assurance that similar volatility will not be
experienced in the future. Factors which may cause added volatility of the Hang
Seng Index include, but are not limited to, those discussed below. (See
"Additional Hong Kong Risk Factors" below.)
    
 
   
    The following table demonstrates the volatility of the Hang Seng Index in
comparison to that of the Financial Times Index and the Dow Jones Industrial
Average by showing for each index the number of trading days during the period
from January 1, 1996 through December 31, 1996 on which the value of the index

    Previous performance is no guarantee of future results; any index may
display more or less volatility in the future.
 
Hong Kong Real Estate Companies
 
   
    The Hang Seng Index is heavily weighted in common stocks of companies
engaged in real estate asset management, development, leasing, property sales
and other related activities. Investment in securities issued by these real
estate companies should be made with an understanding of the many factors which
may have an adverse impact on the credit quality of the particular company or
industry. Generally, these include economic recession, the cyclical nature of
real estate markets, competitive
    
 
                                       9
<PAGE>
overbuilding, the supply of land for construction made available by the Hong
Kong Government, changing demographics, changes in governmental regulations
(including tax laws and environmental, building, zoning and sales regulations),
increases in real estate taxes or costs of material and labor, the inability to
secure performance guarantees or insurance as required, the unavailability of
investment capital and the inability to obtain construction financing or
mortgage loans at rates acceptable to builders and purchasers of real estate.
Additional risks include an inability to reduce expenditures associated with a
property (such as mortgage payments and property taxes) when rental revenue
declines, and possible loss upon foreclosure of mortgaged properties if mortgage
payments are not paid when due.
 
   
    Recently, in the wake of Chinese economic development and reform, certain
Hong Kong real estate companies and other investors began purchasing and
developing real estate in China, including Beijing, the Chinese capital. By
1992, however, some of the major development areas in China began to experience
a rise in real estate prices and construction costs, a growing supply of real
estate and a tightening of credit markets. Since early 1994, the real estate
market in Hong Kong has contracted causing developers to offer significant price
deductions. Speculative activities have abated and rentals have also suffered in
the subdued property market. Any worsening of these conditions could affect the
profitability and financial condition of Hong Kong real estate companies and
could have a materially adverse effect on the value of the Portfolio. Hong Kong
real estate companies also could be materially adversely affected by other
factors, including those discussed below (see "Additional Hong Kong Risk
Factors" below).
    
 
   
Additional Hong Kong Risk Factors
    
 
   
    MOST FAVORED NATION STATUS. China (like most other nations) currently enjoys
a most favored nation status ("MFN Status") from the United States, which is
subject to annual review by the President of the United States. Revocation of
the MFN Status would have a severe effect on China's trade and thus could have a
materially adverse effect on the value of the Portfolio.
    
 
   
    OTHER ECONOMIC FACTORS. Hong Kong is subject to a relatively high inflation
rate of approximately 9% per year. Any downturn in economic growth or increase
in the rate of inflation in Hong Kong could have a materially adverse effect on
the value of the Portfolio. In addition, risks resulting from the $US/$HK
pegging could have an adverse effect on the value of the Portfolio. Because of
Hong Kong's vulnerability as a small country with an open nature, the government
often struggles in its attempt to protect the economy from external influences.
Due to strong economic ties that have developed since 1978, the economy is
particularly affected by factors in China. The performance of certain companies
listed on the Hong Kong Exchange is linked to the economic climate of China. Any
downturn in economic growth or increase in the rate of inflation in China could
have a materially adverse effect on the value of the Portfolio.
    
 
OBJECTIVES AND SECURITIES SELECTION
 
    The objectives of the Trust are (i) to provide income and (ii) to offer
above-average growth potential through an investment for approximately one year
in a fixed diversified portfolio of Securities chosen in the manner described in
the "Summary of Essential Information" in Part A herein. There is, of course, no
guarantee that the Trust's objectives will be achieved.
 
   
    The Trust consists of such of the Securities listed under "Schedule of
Portfolio Securities" as may continue to be held from time to time in the Trust
and any additional Securities and/or contributed cash acquired and held by the
Trust pursuant to the provisions of the Indenture together with undistributed
income therefrom and undistributed cash realized from the disposition of
Securities (See: "Administration of the Trust"). Neither the Sponsor nor the
Trustee shall be liable in any way for any default, failure or defect in any of
the Securities. However, should any contract deposited hereunder fail and no
substitute Security be acquired, the Sponsor shall cause to be refunded the
sales charge relating to such security, plus the portion of the cost of the
failed contract listed under "Schedule of Portfolio Securities".
    
 
                                       10
<PAGE>
    Because certain Securities from time to time may be sold or their percentage
reduced under certain circumstances described herein, and because additional
Securities may be deposited into the Trust from time to time, the Trust is not
expected to retain for any length of time its present size and composition.
(See: "Administration of the Trust--Portfolio Supervision".)
 
    The Trust is organized as a unit investment trust and not as a management
investment company. Therefore, neither the Trustee nor the Sponsor has the
authority to manage the Trust's assets in an attempt to take advantage of
various market conditions to improve the Trust's net asset value, and further,
the Trust's Securities may be disposed of only under limited circumstances.
(See: "Administration of the Trust--Portfolio Supervision".)
 
    There is no assurance that any dividends will be declared or paid in the
future on the Securities initially deposited or to be deposited subsequently in
the Trust.
 
DISTRIBUTION
 
   
    The Record Dates and the Distribution Dates are set forth in Part A hereto.
(See: "Summary of Essential Information".) The distributions will be an amount
equal to such Unit Holder's pro rata portion of the amount of dividend income
received by the Trust (net of any foreign withholding taxes) and proceeds of the
sale of Portfolio Securities, including capital gains, not used for the
redemption of Units, if any (less the Trustee's fees, Sponsor's portfolio
supervision fees and expenses). Distributions for the account of beneficial
owners of Units registered in "street name" and held by the Sponsor will be made
to the investment account of such beneficial owners maintained with the Sponsor.
Whenever required for regulatory or tax purposes or if otherwise directed by the
Sponsor, the Trustee may make special distributions on special distribution
dates to Unit Holders of record on special record dates declared by the Trustee.
    
 
                            TAX STATUS OF THE TRUST
   
    As used herein, the term "U.S. Holder" means an owner of a Unit that is (i)
for United States federal income tax purposes a citizen or resident of the
United States, (ii) a corporation or partnership created under the laws of the
United States or any State thereof, (iii) an estate, the income of which is
subject to United States federal income taxation regardless of its source, or
(iv) a trust, if a court within the United States is able to exercise primary
supervision over the administration of the trust and one or more United States
fiduciaries have the authority to control all substantial decisions of the
trust.
    
 
UNITED STATES TAXATION
 
    In the opinion of Cahill Gordon & Reindel, special counsel for the Sponsor,
under existing Federal income tax law:
 
        The Trust is not an association taxable as a corporation for Federal
    income tax purposes, and income received by the Trust will be treated as
    income of the Unit Holders in the manner set forth below.
 
   
        Each Unit Holder will be considered the owner of a pro rata portion of
    each asset in the Trust under the grantor trust rules of Sections 671-678 of
    the Internal Revenue Code of 1986, as amended (the "Code"). The total tax
    cost of each Unit will equal the cost of Units (including the Initial Sales
    Charge) plus the amount of organizational expenses borne by the Unit Holder.
    A Unit Holder should determine the tax cost (in U.S. dollars) for each asset
    represented by the Holder's Units by allocating the total cost (in U.S.
    dollars) for such Units (including the Initial Sales Charge) among the
    assets in the Trust represented by the Units in proportion to the relative
    fair market values thereof on the date the Unit Holder purchases such Units.
    The proceeds received by a Unit Holder upon termination of the Trust or
    redemption of Units will be paid net of the Deferred Sales Charge. The
    relevant tax reporting forms sent to Unit Holders will also reflect the
    actual amounts paid to them, net of the Deferred Sales Charge. Accordingly,
    Unit Holders should not increase the total cost for their Units by the
    amount of the Deferred Sales Charge.
    
 
                                       11
<PAGE>
   
        A Unit Holder will be considered to have received all of the dividends
    paid on the Holder's pro rata portion of each Security when such dividends
    are received by the Trust including the portion of such dividend used to pay
    ongoing expenses and organizational expenses. The amount of the dividend
    payment will be its U.S. dollar value based on the exchange rate in effect
    on the date the dividend payment is received by the Trust. In the case of a
    corporate Unit Holder, the dividends on the U.S. Securities will qualify for
    the 70% dividends received deduction for corporations to the same extent as
    though the dividend paying stock were held directly by the corporate Unit
    Holder. Dividends considered to have been received by a Unit Holder from
    Foreign Securities will not qualify for the dividends-received deduction for
    corporate Unit Holders because the dividends-received deduction is generally
    only available for dividends received from domestic corporations.
    
 
        As stated below under "United Kingdom Taxation," it is unclear whether
    in practice U.S. Holders will be able to obtain directly Treaty Payments
    (also described below) to which they are entitled under the U.S./U.K. income
    tax treaty (the "Treaty"). However, the Inland Revenue has approved a
    special procedure whereby the Trustee can claim Treaty Payments on behalf of
    U.S. Holders of the U.K. Trust and distribute those payments to Unit
    Holders. To the extent the Trustee obtains Treaty Payments, U.S. Holders
    will report as gross income earned their pro rata share of dividends
    received by the Trust as well as the amount of the associated tax credit
    (described below). Such Holders will be entitled to either a foreign tax
    credit or deduction for the U.K. tax withheld on such refund, assuming other
    limitations on such credit or deduction under the Code do not apply.
 
        An individual Unit Holder who itemizes deductions will be entitled to an
    itemized deduction for the Holder's pro rata share of fees and expenses paid
    by the Trust as though such fees and expenses were paid directly by the Unit
    Holder, but only to the extent that this amount together with the Unit
    Holder's other miscellaneous deductions exceeds 2% of the Holder's adjusted
    gross income. A corporate Unit Holder will not be subject to this 2% floor.
 
        Under the position taken by the Internal Revenue Service in Revenue
    Ruling 90-7, a distribution by the Trustee to a Unit Holder (or to the
    Holder's agent) of such Holder's PRO RATA share of the Securities in kind
    upon redemption or termination of the Trust will not be a taxable event to
    the Unit Holder. Such Unit Holder's basis for Securities so distributed will
    be equal to the Holder's basis for the same Securities (previously
    represented by the Holder's Units) prior to such distribution and the
    holding period for such Securities will be the shorter of the period during
    which the Unit Holder held the Units and the period for which the Securities
    were held in the Trust. A Unit Holder will have a taxable gain or loss,
    which will be a capital gain or loss except in the case of a dealer, when
    the Unit Holder disposes of such Securities in a taxable transfer.
 
        Under the income tax laws of the State and City of New York, the Trust
    is not an association taxable as a corporation and the income of the Trust
    will be treated as the income of the Unit Holders.
 
    The amount of the proceeds received by the Trust from a sale or redemption
of an underlying Security will be the U.S. dollar value of the proceeds based on
the exchange rate in effect on the date of disposition. If the proceeds received
by the Trust upon the sale or redemption of an underlying Security exceed a Unit
Holder's adjusted tax cost allocable to the Security disposed of, that Unit
Holder will realize a taxable gain to the extent of such excess. Conversely, if
the proceeds received by the Trust upon the sale or redemption of an underlying
Security are less than a Unit Holder's adjusted tax cost allocable to the
Security disposed of, that Unit Holder will realize a loss for tax purposes to
the extent of such difference except that upon reinvestment of proceeds in a New
Series the Internal Revenue Service may seek to disallow such loss to the extent
that the underlying securities in each trust are substantially identical and the
purchase of units of the New Series takes place less than thirty-one days after
the sale of the underlying Security. Under the Code, net capital gain (i.e., the
excess of net long-term capital gain over net short-term capital loss) of
individuals, estates and trusts is subject to a maximum nominal tax rate of 28%.
Such net capital gain may, however, result in a disallowance of itemized
deductions and/or affect a personal exemption phase-out. The maximum lower net
capital gain rate will be unavailable to those Unit Holders who have held their
units for less than a year and a day as of the Mandatory Termination Date (or
earlier termination of the Trust) or any day on which a Unit Holder's units are
exchanged or rolled over.

UNITED KINGDOM TAXATION
 
   
    In the opinion of Slaughter and May, special U.K. counsel to the Sponsor,
based on the terms of the Trust as described in the Prospectus, the following
summary accurately describes certain of the U.K. tax consequences to U.S.
Holders of Units of the Trust. This summary is based upon current U.K. law and
Inland Revenue practice, the Treaty and the U.S./U.K. convention relating to
estate and gift taxes (the "Estate Tax Treaty"). The summary is a general guide
only and is subject to any changes in U.K. law, or the practice relating thereto
and in the Treaty or Estate Tax Treaty occurring after the date of this
Prospectus which may affect (including possibly on a retroactive basis) the tax
consequences described herein.
    
 
   
    TAXATION OF DIVIDENDS--Subject to the comments in the following paragraph,
if a U.K. resident receives a dividend from a U.K. corporation, such resident is
generally entitled to a tax credit (currently equal to one quarter of the cash
dividend received), which may be offset against such resident's U.K. taxes, or,
in certain circumstances, repaid. Under the Treaty, a U.S. Holder who holds
shares in a U.K. corporation directly may, in appropriate circumstances, be
entitled to a repayment of that tax credit, but such repayment is subject to
withholding tax at the rate of 15% of the sum of the cash dividend and the
credit (the net amount paid being a "Treaty Payment"). It is unclear, however,
whether a U.S. Holder who holds shares in a U.K. corporation indirectly through
a trust, such as the Trust, would also be entitled to a Treaty Payment where the
dividend payments are made directly to the Trust. Any claim for such a Treaty
Payment would have to be supported by evidence of each U.S. Holder's entitlement
to the relevant dividend. It is therefore uncertain whether U.S. Holders would
in practice be able to secure the benefit of the Treaty and obtain Treaty
Payments directly from the U.K. Inland Revenue. While no formal procedure exists
generally for trusts to claim Treaty Payments on behalf of unitholders, the
Inland Revenue have confirmed a special procedure whereby they will allow the
Trustee to claim Treaty Payments on behalf of the U.S. Holders of the Trust
(treating the Trust, instead of the U.S. Holders, as the beneficiary of the
dividend). This concessionary treatment will enable U.S. Holders to benefit from
Treaty Payments without having to file individual claims with the Inland Revenue
and will avoid the uncertainty of whether in practice a U.S. Holder could obtain
a Treaty Payment.
    
 
    Under the provisions of the Finance Act 1994, after 1st July 1994 a U.K.
company can elect to pay a "foreign income dividend" rather than an ordinary
dividend. If a company whose shares were held in the Portfolio of the Trust pays
a foreign income dividend, no tax credit would be attributable to it and,
therefore, no Treaty Payment could be claimed.
 
    TAXATION OF CAPITAL GAINS--U.S. Holders who are not resident or ordinarily
resident for tax purposes in the U.K. will not be liable for U.K. tax on capital
gains realized on the disposal of their Units unless such units are used, held
or acquired for the purposes of a trade, profession or vocation carried on in
the U.K. through a branch or agency or for the purposes of such branch or
agency.
 
    U.K. INHERITANCE TAX--An individual Holder who is domiciled in the U.S. for
the purposes of the Estate Tax Treaty and who is not a national of the U.K. for
the purposes of the Estate Tax Treaty will not generally be subject to U.K.
inheritance tax in respect of Units in the Trust on the individual's death or on
a gift of such Units during the individual's lifetime provided that any
applicable U.S. federal gift or estate tax liability is paid, unless the Units
are part of the business property of a permanent establishment of the individual
in the U.K. or pertain to a fixed base in the U.K. used by an individual for the
performance of independent personal services. In the exceptional case where the
Units are subject both to U.K. inheritance tax and to U.S. federal gift or
estate tax, the Estate Tax Treaty generally provides for the tax paid in the
U.K. to be credited against tax paid in the U.S. or for tax paid in the U.S. to
be credited against tax payable in the U.K. based on priority rules set out in
that Treaty.
 
   
    For the U.S. tax consequences to U.S. Holders, see "United States Taxation."
The taxation of non-U.S. Holders in the U.K. and in their own countries of
residence as a result of their ownership, sale, exchange or other disposition of
Units of the Trust will be governed by the relevant treaties, if any, between
the countries of residence of such non-U.S. Holders and the U.K. and by the
internal tax laws of such countries.

HONG KONG TAXATION
 
   
    In the opinion of Slaughter and May, special Hong Kong counsel to the
Sponsor, the following summary accurately describes the Hong Kong tax
consequences under existing law to all U.S. Holders of Units of the Trust. This
discussion is for general purposes only and assumes that such U.S. Holder is not
carrying on a trade, profession or business in Hong Kong and has no profits
arising in or derived from Hong Kong in respect of the carrying on of such
trade, profession or business. Holders should consult their tax advisors as to
the Hong Kong tax consequences of ownership of the Units of the Trust applicable
to their particular circumstances.
    
   
    TAXATION OF DIVIDENDS--Amounts in respect of dividends paid to U.S. Holders
of Units of the Trust are not taxable under current legislation and practice and
therefore will not be subject to the deduction of any withholding tax.
    
   
    PROFITS TAX--A U.S. Holder of Units of the Trust (other than a person
carrying on a trade, profession or business in Hong Kong) will not be subject to
profits tax on any gain or profits made on the realization or other disposal of
such Units.
    
 
    ESTATE DUTY--Ownership of Units of the Trust will not give rise to a
liability to Hong Kong estate duty.
   
    HONG KONG STAMP DUTY--No Hong Kong stamp duty will be payable in respect of
transactions in Units of the Trust.
    
   
    The foregoing discussion addresses only the Hong Kong tax consequences to
Holders of Units in the Trust. For the U.S. tax consequences to U.S. Holders,
see "United States Taxation." The taxation of non- U.S. Holders in their own
countries of residence as a result of their ownership, sale, exchange or other
disposition of Units in the Trust will be governed by the internal tax laws of
the countries of residence of such non-U.S. Holders.
    
 
    UNIT HOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE
APPLICATION OF THE ABOVE GENERAL INFORMATION TO THEIR OWN PERSONAL SITUATION.
 
                                RETIREMENT PLANS
 
    Units of the Trust may be suited for purchase by Individual Retirement
Accounts and pension plans or profit sharing and other qualified retirement
plans. Investors considering participation in any such plan should review
specific tax laws and pending legislation relating thereto and should consult
their attorneys or tax advisors with respect to the establishment and
maintenance of any such plan.
 
    A qualified retirement plan provides employee retirement benefits and is
funded by contributions from the employer (including contributions by a
self-employed individual, in which case the plan is sometimes called a Keogh
plan). The contributions are, within limits, deductible in determining the
taxable income of the contributing employer for Federal income tax purposes.
Income received by the plan is not taxed when received by it (nor are plan
losses deductible), but distributions from the plan are generally included in
ordinary income of the distributee upon receipt. A lump sum payout of the entire
amount held in such a plan can, however, be eligible for 5 or 10 year averaging.
 
    An individual retirement account (an "IRA") is similar to a qualified
retirement plan but contributions to an IRA up to $2,000 per year are generally
made by an individual from earned income, rather than by an employer.
(Additional contributions of up to $2,000 may also be made to an IRA of an
individual's spouse provided the combined income of the individual and his or
her spouse is sufficient.) An individual is permitted to contribute to an IRA
even though he or she is also covered by a qualified retirement plan; but, in
the case of higher-income individuals who are active participants in a qualified
retirement plan, IRA contributions are neither currently deductible nor taxed
when paid out by the IRA (although income earned in the IRA is taxed as ordinary
income when distributed). The IRA beneficiary must not have attained age 70 1/2
by the close of the taxable year for which an IRA contribution is made; and 5
and 10 year averaging is not allowable for IRA distributions.
 
                                       14
<PAGE>
    Distributions from qualified retirement plans must begin in minimum amounts
no later than the April 1 following the calendar year in which the employee
attains age 70 1/2 (or in the case of a person other than a 5% owner, April 1 of
the calendar year in which the employee retires, if later) or within 5 years
after his or her prior death if death occurs before distributions begin (with
later distribution allowed for a surviving spouse and with lifetime annuity-type
payouts to any beneficiary permitted). Minimum required distributions from IRAs
are governed by similar rules (except that minimum distributions to the
individual for whom the IRA is maintained must in all cases begin no later than
the April 1 following the calendar year in which the individual attains age
70 1/2).
 
    Forms and arrangements for establishing qualified retirement plans and IRAs
are available from the Sponsor, as well as from other brokerage firms, other
financial institutions and others. Fees and charges with respect to such plans
and IRAs are not uniform and may vary from time to time as well as from
institution to institution.
 
    Distributions received from a qualified retirement plan or IRA before the
employee attains age 59 1/2 are subject to a 10% additional tax, unless the
distribution is (i) made on or after the employee's death, (ii) attributable to
his disablement, (iii) in the nature of a life annuity, (iv) made to the
employee after separation from service after attainment of age 55, or (v) made
for other reasons specified in the law. Qualifying distributions from a
qualified retirement plan or from an IRA may, however, be rolled over or
transferred to another qualified retirement plan or IRA under specified
circumstances.
 
    The foregoing information is of a general nature, does not purport to be
complete and relates only to the Federal income tax rules applicable to
qualified retirement plans and IRAs. State and local tax rules and foreign tax
regimes may treat qualified retirement plans and IRAs differently. Anyone
contemplating establishing a qualified retirement plan or IRA or investing funds
of such a plan or IRA in Trust units should consult his, her or its tax advisor
with respect to the tax consequences of any such action and the application of
the foregoing general tax information to his, her or its particular situation.
 
                            PUBLIC OFFERING OF UNITS
 
PUBLIC OFFERING PRICE
 
   
    The Public Offering Price of the Units is calculated on each business day
and is computed by adding to the aggregate U.S. dollar market value of the
Portfolio Securities (as determined by the Trustee) next computed after receipt
of a purchase order, divided by the number of Units outstanding, the sales
charge shown in "Summary of Essential Information". In order to enable
purchasers of Units on the date of this Prospectus to purchase Units at a Public
Offering Price of $10.00 per Unit, the Units outstanding as of the Evaluation
Time on the date of this Prospectus (all of which are held by the Sponsor) may
be split (or split in reverse). Commissions and any other transactional costs,
if any, incurred by the Sponsor in connection with the deposit of additional
Securities or contracts to purchase additional Securities for the creation of
Additional Units will be added to the Public Offering Price. After the initial
Date of Deposit, a proportionate share of amounts in the Income Account and
Principal Account and amounts receivable in respect of stocks trading
ex-dividend (other than money required to be distributed to Unit Holders on a
Distribution Date and money required to redeem tendered Units) is added to the
Public Offering Price. In the event a stock is trading ex-dividend at the time
of deposit of additional Securities, an amount equal to the dividend that would
be received if such stock were to receive a dividend will be added to the Public
Offering Price. The Public Offering Price per Unit is calculated to five decimal
places and rounded up or down to three decimal places. The Public Offering Price
on any particular date will vary from the Public Offering Price on the Date of
Deposit (set forth in the "Summary of Essential Information") in accordance with
fluctuations in the aggregate market value of the Securities, the amount of
available cash on hand in the Trust, the amount of certain accrued fees and
expenses and changes in the relevant foreign currency exchange rates and
applicable commissions.
    
 
    The sales charge consists of an Initial Sales Charge and a Deferred Sales
Charge. The Initial Sales Charge is computed by deducting the Deferred Sales
Charge ($20.00 per 100 Units) from the aggregate sales charge. The Initial Sales
Charge paid by a
 
                                       15
<PAGE>
   
Unit Holder may be more or less than the Initial Sales Charge on the Date of
Deposit due to the fluctuation of the value of the Securities from that on the
Date of Deposit. The Deferred Sales Charge will initially be $20.00 per 100
Units but will be reduced each month by one tenth; the Deferred Sales Charge
will be paid through monthly payments of $2.00 per 100 Units per month
commencing on the first Deferred Sales Charge Payment Date as shown on the
Summary of Essential Information through the sale of Securities on each such
date or distribution of cash available for such payment. To the extent the
entire Deferred Sales Charge has not been so paid at the time of repurchase,
redemption or exchange of the Units, any unpaid amount will be deducted from the
proceeds or in calculating an in kind distribution. For purchases of Units with
a value of $25,000 or more, the Initial Sales Charge is reduced on a graduated
basis as shown below under "Volume Discount". Units purchased pursuant to the
Reinvestment Program are subject only to any remaining Deferred Sales Charge
payments (see "Reinvestment Program").
    
 
    As more fully described in the Indenture, the aggregate U.S. dollar market
value of the Securities is determined on each business day by the Trustee based
on closing prices and relevant currency exchange rates on the day the valuation
is made or, if there are no such reported prices, by taking into account the
same factors referred to under "Redemption--Computation of Redemption Price",
except that the relevant exchange rate used for determining the value of
Securities in foreign currency may include the cost of any forward contract to
purchase the relevant currency. The term business day, as used herein and under
"Redemption", shall exclude Saturdays, Sundays and the following holidays as
observed by the New York Stock Exchange, Inc.: New Year's Day, Washington's
Birthday, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving
and Christmas Day. Determinations are effective for transactions effected
subsequent to the last preceding determination.
 
PUBLIC DISTRIBUTION
 
    Units issued on the Date of Deposit and Additional Units issued in respect
of additional deposits of Securities will be distributed to the public by the
Sponsor and through dealers at the Public Offering Price determined as provided
above. Unsold Units or Units acquired by the Sponsor in the secondary market
referred to below may be offered to the public by this Prospectus at the then
current Public Offering Price determined as provided above.
 
    The Sponsor intends to qualify Units in states selected by the Sponsor for
sale by the Sponsor and through dealers who are members of the National
Association of Securities Dealers, Inc. Sales to dealers during the initial
offering period will be made at prices which reflect a concession of 65% of the
applicable sales charge, subject to change from time to time. In addition, sales
of Units may be made pursuant to distribution arrangements with certain banks
and/or other entities subject to regulation by the Office of the Comptroller of
the Currency which are acting as agents for their customers. These banks and/or
entities are making Units of the Trust available to their customers on an agency
basis. A portion of the sales charge paid by these customers is retained by or
remitted to such banks or entities in an amount equal to the fee customarily
received by an agent for acting in such capacity in connection with the purchase
of Units. The Glass-Steagall Act prohibits banks from underwriting certain
securities, including Units of the Trust; however, this Act does permit certain
agency transactions, and banking regulators have not indicated that these
particular agency transactions are impermissible under this Act. In Texas, as
well as certain other states, any bank making Units available must be registered
as a broker-dealer in that State. The Sponsor reserves the right to reject, in
whole or in part, any order for the purchase of Units.
 
SECONDARY MARKET
 
   
    While not obligated to do so, it is the Sponsor's present intention to
maintain, at its expense, a secondary market for Units of this series of the
Dean Witter Select Equity Trust and to continuously offer to repurchase Units
from Unit Holders at the Sponsor's Repurchase Price. The Sponsor's Repurchase
Price is computed by adding to the aggregate U.S. dollar value of the Securities
in the Trust based on the applicable exchange rate, any cash on hand in the
Trust including dividends receivable on stocks trading ex-dividend (other than
money required to redeem tendered Units and cash deposited by the Sponsor to
purchase Securities or cash held in the Reserve Account) and deducting therefrom
expenses of the Trust, Sponsor, counsel and taxes, if any, any remaining
    
 
                                       16
<PAGE>
unpaid portion of the Deferred Sales Charge and cash held for distribution to
Unit Holders of record as of a date on or prior to the evaluation; and then
dividing the resulting sum by the number of Units outstanding, as of the date of
such computation. In addition, after the initial offering period, the Sponsor's
Repurchase Price will be reduced to reflect the Trust's estimated costs of
liquidating the Securities to meet redemption requests. There is no sales charge
incurred when a Unit Holder sells Units back to the Sponsor other than the
payment of the unpaid portion of the Deferred Sales Charge. Any Units
repurchased by the Sponsor at the Sponsor's Repurchase Price may be reoffered to
the public by the Sponsor at the then current Public Offering Price. Any profit
or loss resulting from the resale of such Units will belong to the Sponsor.
 
    If the supply of Units exceeds demand (or for any other business reason),
the Sponsor may, at any time, occasionally, from time to time, or permanently,
discontinue the repurchase of Units of this series at the Sponsor's Repurchase
Price. In such event, although under no obligation to do so, the Sponsor may, as
a service to Unit Holders, offer to repurchase Units at the "Redemption Price".
Alternatively, Unit Holders may redeem their Units through the Trustee.
 
PROFIT OF SPONSOR
 
    The Sponsor receives a sales charge on Units sold to the public and to
dealers. The Sponsor may have also realized a profit (or sustained a loss) on
the deposit of the Securities in the Trust representing the difference between
the cost of the Securities to the Sponsor and the cost of the Securities to the
Trust (for a description of such profit (or loss) and the amount of such
difference on the initial Date of Deposit see: "Schedule of Portfolio
Securities"). The Sponsor may realize a similar profit (or loss) in connection
with each additional deposit of Securities. In addition, the Sponsor may have
acted as broker in transactions relating to the purchase of Securities for
deposit in the Trust. During the initial public offering period the Sponsor may
realize additional profit (or sustain a loss) due to daily fluctuations in the
prices of the Securities in the Trust and thus in the Public Offering Price of
Units received by the Sponsor. Cash, if any, received by the Sponsor from the
Unit Holders prior to the settlement date for purchase of Units or prior to the
payment for Securities upon their delivery may be used in the Sponsor's business
and may be of benefit to the Sponsor.
 
    The Sponsor may also realize profits (or sustain losses) while maintaining a
secondary market in the Units, in the amount of any difference between the
prices at which the Sponsor buys Units and the prices at which the Sponsor
resells such Units (such prices include a sales charge) or the prices at which
the Sponsor redeems such Units, as the case may be.
 
VOLUME DISCOUNT
 
    Although under no obligation to do so, the Sponsor intends to permit volume
purchasers of Units to purchase Units at a reduced sales charge. The Sponsor may
at any time change the amount by which the sales charge is reduced, or may
discontinue the discount altogether.
 
                                       17
<PAGE>
    The sales charge of 2.90% of the Public Offering Price will be reduced
pursuant to the following graduated scale for sales to any person of at least
$25,000 during the Initial Offering Period. The sales charge in the secondary
market, which will be reduced pursuant to the following graduated scale,
consists of an Initial Sales Charge and the remaining portions of the Deferred
Sales Charge. The reductions indicated will be applied to the Initial Sales
Charge.

    The reduced sales charges as shown on the chart above will apply to all
purchases of Units of this Trust on any one day by the same person, partnership
or corporation (other than a dealer), in the amounts stated herein. For
purchases of $250,000.00 or more, the sales charge consists solely of deferred
sales charge of $20.00 per 100 units for a purchase of $250,000.00 to
$999,999.99 and adjusted to total $10.00 per 100 units for a purchase of
$1,000,000.00 or more.
    
 
    Units held in the name of the purchaser's spouse or in the name of a
purchaser's child under the age 21 are deemed for the purposes hereof to be
registered in the name of the purchaser. The reduced sales charges are also
applicable to a trustee or other fiduciary, including a partnership or
corporation purchasing Units for a single trust estate or single fiduciary
account.
 
    The dealer concession will be 65% of the sales charge per Unit.
 
                                   REDEMPTION
 
RIGHT OF REDEMPTION
 
    One or more Units may be redeemed at the Redemption Price upon delivery of a
request for redemption to the Trustee at its unit investment trust office in the
City of New York, in form satisfactory to the Trustee. A Unit Holder may tender
its Units for redemption at any time after the settlement date for purchase. The
Redemption Price per Unit is calculated as set forth under "Computation of
Redemption Price". There is no sales charge incurred when a Unit Holder tenders
its Units to the Trustee for redemption other than the payment of any Deferred
Sales Charge then due. The London Stock Exchange and the Hong Kong Exchange are
open for trading on certain days which are U.S. holidays on which the Trust will
not transact business. The Foreign Securities will continue to trade on those
days and thus the value of the Portfolio may be significantly affected on days
when a Unit Holder cannot sell or redeem Units.
 
    On the third business day following the tender to the Trustee of Units to be
redeemed the Unit Holder will be entitled to receive monies per Unit equal to
the Redemption Price per Unit as determined by the Trustee as of the Evaluation
Time on the date of tender.
 
    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 next Business Day
following such presentation.
 
                                       18
<PAGE>
   
    Units will be redeemed by the Trustee solely in cash for any one Unit Holder
tendering Units with a value of less than $500,000. With respect to redemption
requests regarding Units with a value greater than $500,000, the Sponsor may
determine, in its discretion, to direct the Trustee to redeem Units "in kind" by
distributing Portfolio Securities to the redeeming Unit Holder. 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. Unit Holders redeeming "in kind" will
receive an amount and value of Trust Securities per Unit equal to the Redemption
Price Per Unit as determined as of the Evaluation Time next following the tender
as set forth herein under "Computation of Redemption Price" below. The
distribution "in kind" for redemption of Units will be held by the Trustee for
the account of, and for disposition in accordance with the instructions of, the
tendering Unit Holder. The tendering Unit Holder will be entitled to receive
whole shares of each of the underlying Portfolio Securities, plus cash equal to
the Unit Holder's pro rata share of the cash balance of the Income and Principal
Accounts and cash from the Principal Account equal to the fractional shares to
which such tendering Unit Holder is entitled. The Trustee, in connection with
implementing the redemption "in kind" procedures outlined above, may make any
adjustments necessary to reflect differences between the Redemption Price of
Units and the value of the Securities distributed "in kind" as of the date of
tender. If the Principal Account does not contain amounts sufficient to cover
the required cash distribution to the tendering Unit Holder, the Trustee is
empowered to sell Securities in the Trust Portfolio in the manner discussed
below. A Unit Holder receiving redemption distributions of Securities "in kind"
may incur brokerage costs and odd-lot charges in converting Securities so
received into cash. The Trustee will assess transfer charges to Unit Holders
taking Securities "in kind" according to its usual practice. Any U.K. or Hong
Kong stamp duty imposed on the transfer of shares from the Portfolio in
connection with a redemption "in kind" will be borne by the redeeming Unit
Holder.
    
 
   
    The portion of the Redemption Price which represents the Unit Holder's
interest in the Income Account shall be withdrawn from the Income Account to the
extent available. The balance paid on any redemption, including dividends
receivable on stocks trading ex-dividend, if any, shall be drawn from the
Principal Account to the extent that funds are available for such purpose. The
Trustee is authorized by the Agreement to sell Securities in order to provide
funds for redemption. To the extent Securities are sold, the size and diversity
of the Trust will be reduced. Such sales may be required at a time when
Securities would not otherwise be sold and might result in lower prices than
might otherwise be realized. The Redemption Price received by a tendering Unit
Holder may be more or less than the purchase price originally paid by such Unit
Holder, depending on the value of the Securities in the Portfolio at the time of
redemption. Moreover, due to the minimum lot size in which Securities may be
required to be sold, the proceeds of such sales may exceed the amount necessary
for payment of Units redeemed. Such excess proceeds will be distributed pro rata
to all remaining Unit Holders of record on the next following Record Date.
    
 
    Securities to be sold for purposes of redeeming Units will be selected from
a list supplied by the Sponsor. If not so instructed by the Sponsor, the Trustee
will select the Securities to be sold so as to maintain, as closely as
practicable, the proportionate relationship between the number of shares of each
Security in the Trust.
 
COMPUTATION OF REDEMPTION PRICE
 
    The Trust Evaluation per Unit is determined as of the Evaluation Time stated
under "Summary of Essential Information" above (a) semiannually, on the last
Business Day of each of the months of June and December, (b) on the day on which
any Unit of the Trust is tendered for redemption (unless tender is made after
the Evaluation Time on such day, in which case Tender shall be deemed to have
been made on the next day subsequent thereto on which the New York Stock
Exchange is open for trading) and (c) on any other Business Day desired by the
Sponsor or the Trustee, (1) by adding:
   
        a.  The aggregate U.S. dollar value of Securities in the Trust based on
    the bid side of the applicable exchange rate, as determined by the Trustee;
    
   
        b.  Cash on hand in the Trust (in U.S. dollars based on the applicable
    exchange rate), including dividends receivable on stocks trading
    ex-dividend, other than money deposited to purchase Securities or money
    credited to the Reserve Account;
    
 
                                       19
<PAGE>
        c.  All other assets of the Trust.
 
    (2) and then, by deducting from the resulting figure: amounts representing
any applicable taxes or governmental charges payable by the Trust for the
purpose of making an addition to the reserve account (as defined in the
Agreement, the "Reserve Account"), amounts representing estimated accrued fees
and expenses of the Trust (including legal and auditing expenses), amounts
representing unpaid fees of the Trustee, the Sponsor and counsel, any remaining
unpaid portion of the Deferred Sales Charge and monies held to redeem tendered
Units and for distribution to Unit Holders of record as of the Business Day
prior to the Evaluation being made on the days or dates set forth above and
then;
 
    (3) by dividing the result of the above computation by the total number of
Units outstanding on the date of such Evaluation. The resulting figure equals
the Redemption Price for each Unit.
 
    In addition, after the initial offering period, the Redemption Price will be
reduced to reflect the Trust's estimated costs of liquidating the Securities to
meet the redemption.
 
   
    The aggregate value of the Securities shall be determined by the Trustee in
good faith in the following manner: If the Securities are listed on one or more
national securities exchanges, such valuation shall be based on the closing
price on such exchange which is the principal market thereof and which shall be
deemed to be the New York Stock Exchange if the Securities are listed thereon
(unless the Trustee deems such price inappropriate as a basis for valuation). If
the Securities are not so listed, or, if so listed and the principal market
therefor is other than such exchange or there is no closing price on such
exchange, such valuation shall be based on the closing price in the
over-the-counter market (unless the Trustee deems such price inappropriate as a
basis for valuation) or if there is no such closing price, by any of the
following methods which the Trustee deems appropriate: (i) on the basis of
current bid prices of such Securities as obtained from investment dealers or
brokers (including the Depositor) who customarily deal in securities comparable
to those held by the Trust, or (ii) if bid prices are not available for any of
such Securities, on the basis of bid prices for comparable securities, or (iii)
by appraisal of the value of the Securities on the bid side of the market or by
such other appraisal as is deemed appropriate, or (iv) by any combination of the
above. The valuation of a foreign Security may take into consideration events or
announcements occurring after the close of the related foreign securities
exchange and prior to the Evaluation Time which could have a material effect on
the value of a Security. The relevant exchange rate used for evaluations of the
Securities will include the cost of any forward foreign exchange contract in the
relevant currency to correspond to the Trustee's settlement requirements for
redemption requests.
    
 
POSTPONEMENT OF REDEMPTION
 
    The right of redemption may be suspended and payment of the Redemption Price
per Unit postponed for more than seven calendar days following a tender of Units
for redemption (i) for any period during which the New York Stock Exchange, Inc.
is closed, other than for customary weekend and holiday closings, or (ii) for
any period during which, as determined by the Securities and Exchange
Commission, either trading on the New York Stock Exchange, Inc. is restricted or
an emergency exists as a result of which disposal or evaluation of the
Securities is not reasonably practicable, or (iii) for such other periods as the
Securities and Exchange Commission may by order permit. The Trustee is not
liable to any person or in any way for any loss or damage that may result from
any such suspension or postponement.
 
                                EXCHANGE OPTION
 
    Unit Holders of any Dean Witter Select Trust or any holders of units of any
other unit investment trust (collectively, "Holders") may elect to exchange any
or all of their units for units of one or more of any series of the Dean Witter
Select Equity Trust or for units of any other Dean Witter Select Trusts, that
may from time to time be made available for such exchange by the Sponsor (the
"Exchange Trusts"). Such an exchange is implemented by a sale of Units and a
purchase of the units of an Exchange Trust. Such
 
                                       20
<PAGE>
   
units may be acquired at prices based on reduced sales charges per unit. The
purpose of such reduced sales charge is to permit the Sponsor to pass on to the
Holder who wishes to exchange units the cost savings resulting from such
exchange. The cost savings result from reductions in time and expense related to
advice, financial planning and operational expense required for the Exchange
Option. The following Exchange Trusts are currently available: the Dean Witter
Select Municipal Trust, the Dean Witter Select Government Trust and the Dean
Witter Select Equity Trust.
    
 
    Each Exchange Trust has different investment objectives: a Holder should
read the Prospectus for the applicable Exchange Trust carefully to determine the
investment objective prior to exercise of this option.
 
    This option will be available provided the Sponsor maintains a secondary
market in units of the applicable Exchange Trust and provided that units of the
applicable Exchange Trust are available for sale and are lawfully qualified for
sale in the state in which the Holder is a resident. While it is the Sponsor's
present intention to maintain a secondary market for the units of Exchange
Trusts, there is no obligation on its part to do so. Therefore, there is no
assurance that a market for units will in fact exist on any given date in which
a Holder wishes to sell or exchange Units; thus, there is no assurance that the
Exchange Option will be available to any Unit Holder. The Sponsor reserves the
right to modify, suspend or terminate this option. Sixty days notice will be
given prior to the date of the termination of or a material amendment to the
Exchange Option except that no notice need be given in certain circumstances
approved by the Securities and Exchange Commission. In the event the Exchange
Option is not available to a Unit Holder at the time such Unit Holder wishes to
exercise such option, the Unit Holder will be immediately notified and no action
will be taken with respect to such tendered Units without further instruction
from the Unit Holder.
 
    Exchanges will be affected in whole units only. Any excess proceeds from the
surrender of a Unit Holder's Units will be returned. Alternatively, Unit Holders
will be permitted to make up any difference between the amount representing the
Units being submitted for exchange and the amount representing the units being
acquired up to the next highest number of whole units.
 
    An exchange of Units pursuant to the Exchange Option will constitute a
"taxable event" under the Code, i.e., a Holder will recognize a gain or loss at
the time of exchange, except that, upon an exchange of Units for units of any
series of the Exchange Trusts which are grantor trusts for U.S. federal income
tax purposes the Internal Revenue Service may seek to disallow any loss incurred
upon such exchange to the extent that the underlying securities in each Trust
are substantially identical and the purchase of the units of an Exchange Trust
takes place less than thirty-one days after the sale of the Units. In order to
avoid the potential disallowance of losses for tax purposes, a Unit Holder may
notify the Sponsor that the Unit Holder desires to purchase units of the
Exchange Trust on the thirty-first day after the day of the sale of the Units
exchanged. The proceeds of the Units surrendered will be deposited in the Unit
Holder's brokerage account at the Sponsor and may be withdrawn at any time. Cash
from the account will be utilized to purchase units of the Exchange Trust on the
thirty-first day after the day of sale of the Units exchanged in accordance with
the procedures set forth above. A Unit Holder may revoke the order to purchase
at any time prior to the purchase on the thirty-first day by calling his
financial advisor. Units will be purchased at a price based upon the net asset
value per unit plus the applicable sales charge of 2.0%. However, there can be
no assurance that a market for units will exist on such date or that units will
be available for purchase on such date. If units are unavailable, the Sponsor
may acquire units in the secondary market or create units as soon as possible
thereafter, which units will be sold by the Sponsor based on the net asset value
on the date of purchase of the units plus the applicable sales charge of 2.0%.
The order does not create a contract or option to acquire units. If units are
not held in the Sponsor's inventory on the 31st day or if the Sponsor does not
create additional units or is unable to acquire units in the secondary market,
units of the Exchange Trust will not be purchased and the cash will remain in
the Unit Holder's account. A Unit Holder who exchanges Units of one Trust for
units of another Trust should consult his or her tax advisor regarding the
extent to which such exchange results in the recognition of a loss for Federal
and/or state or local income tax purposes.
 
    To exercise the Exchange Option, a Unit Holder should notify the Sponsor of
the desire to acquire units of one or more of the Exchange Trusts. Upon the
exchange of Units of the Trust, any Deferred Sales Charge balance will be
deducted from the exchange
 
                                       21
<PAGE>
proceeds. If units of the applicable outstanding series of the Exchange Trust
are at that time available for sale, the Unit Holder may select the series or
group of series for which the Units are to be exchanged. The Unit Holder will be
provided with a current prospectus or prospectuses relating to each series in
which interest is indicated.
 
    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 upon the aggregate bid side evaluation per Unit of the Securities in the
Portfolio. Units of the Exchange Trust will be sold to the Unit Holder at a
price equal to the net asset value based on the offering or bid side evaluation
(as applicable) per unit of the securities in the Exchange Trust's Portfolio,
plus accrued interest, if any, and the applicable sales charge of 2.0% of the
Public Offering Price per Unit. If the Exchange Trust is a series of Dean Witter
Select Equity Trust, Select 10 Industrial Portfolio Series or Select 5
Industrial Portfolio Series the applicable sales charge on such Trust will be
the Deferred Sales Charge of such Trust which may be more or less than 2.0% of
the Public Offering Price.
 
   
                              REINVESTMENT PROGRAM
    
 
    Unit Holders may elect to have the distributions with respect to their Units
automatically reinvested in additional Units of the Trust subject only to any
remaining portions of the Deferred Sales Charge. (Reinvestment Units are not
subject to the Initial Sales Charge.) The Unit Holder may participate in the
Trust's reinvestment program (the "Program") by filing with the Trustee a
written notice of election. The Unit Holder's completed notice of election to
participate in the Program must be received by the Trustee at least ten days
prior to the Record Date applicable to any distribution in order for the Program
to be in effect as to such distribution. Elections may be modified or revoked on
similar notice.
 
    Such distributions, to the extent reinvested in the Trust, will be used by
the Trustee at the direction of the Sponsor in one or both of the following
manners. (i) The distributions may be used by the Trustee to purchase Units of
this Series of the Trust held in the Sponsor's inventory. The purchase price
payable by the Trustee for each of such Units will be equal to the applicable
Trust evaluation per Unit on (or as soon as possible after) the close of
business on the Distribution Date. The Units so purchased by the Trustee will be
issued or credited to the accounts of Unit Holders participating in the Program.
(ii) If there are no Units in the Sponsor's inventory, the Sponsor may purchase
additional Securities for deposit into the Trust (as described in "Prospectus
Part B--Introduction.") The additional Securities with any necessary cash will
be deposited by the Sponsor with the Trustee in exchange for new Units. The
distributions may then be used by the Trustee to purchase the new Units from the
Sponsor. The price for such new Units will be the applicable Trust evaluation
per Unit on (or as soon as possible after) the close of business on the
Distribution Date. (See "Public Offering of Units--Public Offering Price.") The
Units so purchased by the Trustee will be issued or credited to the accounts of
Unit Holders participating in the Program. The Sponsor may terminate the Program
if it does not have sufficient Units in its inventory or it is no longer deemed
practical to create additional Units.
 
    No fractional Units will be issued under any circumstances. If, after the
maximum number of full Units has been issued or credited at the applicable
price, there remains a portion of the distribution which is not sufficient to
purchase a full Unit at such price, the Trustee will distribute such cash to
Unit Holders. The cost of administering the reinvestment program will be borne
by the Trust and thus will be borne indirectly by all Unit Holders.
 
                             RIGHTS OF UNIT HOLDERS
 
UNIT HOLDERS
 
    A Unit Holder is deemed to be a beneficiary of the Trust created by the
Indenture and Agreement and vested with all right, title and interest in the
Trust created therein. A Unit Holder may at any time tender its Units to the
Trustee for redemption.
 
                                       22
<PAGE>
    Unit Holders are required to hold their Units in uncertificated form. The
Trustee will credit a Unit Holder's account with the number of Units held by the
Unit Holder. Units are transferable only on the records of the Trustee upon
presentation of evidence satisfactory to the Trustee for each transfer and any
sums payable for taxes or other governmental charges imposed upon these
transactions and compliance with the formalities necessary to redeem Units.
 
CERTAIN LIMITATIONS
 
    The death or incapacity of any Unit Holder will not operate to terminate the
Trust nor entitle the legal representatives or heirs of such Unit Holder to
claim an accounting or to take any other action or proceeding in any court for a
partition or winding up of the Trust.
 
   
    No Unit Holder shall have the right to vote except with respect to removal
of the Trustee or amendment and termination of the Trust. (See: "Administration
of the Trust--Amendment" and "Administration of the Trust--Termination".) Unit
Holders shall have no right to control the operation or administration of the
Trust in any manner, except upon the vote of 51% of the Units outstanding at any
time for purposes of amendment, or termination of the Trust or discharge of the
Trustee, all as provided in the Agreement; however, no Unit Holder shall ever be
under any liability to any third party for any action taken by the Trustee or
Sponsor. Unit Holders will be unable to dispose of any of the Securities in the
Portfolio, as such, and will not be able to vote the Securities. The Trustee, as
holder of the Securities, will have the right to vote all of the voting
Securities held in the Trust, and will vote such Securities in accordance with
the instructions of the Sponsor, if given. Otherwise the Trustee shall vote as
it, in its sole discretion, shall determine.
    
 
                              EXPENSES AND CHARGES
 
EXPENSES
 
    All or a portion of the organizational expenses and charges incurred in
connection with the establishment of the Trust including the cost of the
preparation, printing and execution of the Indenture, Registration Statement and
other documents relating to the Trust, Federal and State registration fees and
costs, the initial fees and expenses of the Trustee and legal and auditing
expenses will be paid by the Trust and amortized over the life of the Trust.
Historically, the costs of establishing unit investment trusts have been borne
by a trust's sponsor. Advertising and selling expenses will be paid by the
Sponsor at no cost to the Trust.
 
FEES
 
   
    The Sponsor's fee, earned for portfolio supervisory services, is based upon
the largest number of Units outstanding during the computation period. The
Sponsor's fee as set forth in "Summary of Essential Information" may exceed the
actual costs of providing portfolio supervisory services for this Trust, but at
no time will the total amount the Sponsor receives for portfolio supervisory
services rendered to all series of the Dean Witter Select Equity Trust in any
calendar year exceed the aggregate cost to it of supplying such services in such
year.
    
 
    Under the Indenture and Agreement for its services as Trustee and evaluator,
the Trustee receives the fee set forth in "Summary of Essential Information".
Certain regular expenses of the Trust, including certain mailing and printing
expenses, are borne by the Trust.
 
    The Sponsor's fee, the Trustee's fees and the Trust expenses accrue daily
but are payable only on or before each Distribution Date from the Income
Account, to the extent funds are available and thereafter from the Principal
Account. Any of such fees may be increased without approval of the Unit Holders
in proportion to increases under the classification "All Services Less Rent" in
the
 
                                       23
<PAGE>
Consumer Price Index published by the United States Department of Labor or, if
no longer published, a similar index. The Trustee, pursuant to normal banking
procedures, also receives benefits to the extent that it holds funds on deposit
in various non-interest bearing accounts created under the Indenture and
Agreement.
 
OTHER CHARGES
 
    The following additional charges are or may be incurred by the Trust as more
fully described in the Indenture and Agreement: (a) fees of the Trustee for
extraordinary services, (b) expenses of the Trustee (including legal and
auditing expenses) and of counsel designated by the Sponsor, (c) various
governmental charges, (d) expenses and costs of any action taken by the Trustee
to protect the Trust and the rights and interests of the Unit Holders, (e)
indemnification of the Trustee for any loss, liability or expenses incurred by
it in the administration of the Trust without gross negligence, bad faith,
wilful malfeasance or wilful misconduct on its part or reckless disregard of its
obligations and duties, (f) indemnification of the Sponsor for any losses,
liabilities and expenses incurred in acting as Sponsor or Depositor under the
Agreement without gross negligence, bad faith, wilful malfeasance or wilful
misconduct or reckless disregard of its obligations and duties, (g) expenditures
incurred in contacting Unit Holders upon termination of the Trust, and (h)
brokerage commissions or charges incurred in connection with the purchase or
sale of Securities.
 
PAYMENT
 
    The fees and expenses set forth herein are payable out of the Trust and when
so paid by or owing to the Trustee are secured by a lien on the Trust. Dividends
on the Securities are expected to be sufficient to pay the estimated expenses of
the Trust. If the balances in the Income and Principal Account are insufficient
to provide for amounts payable by the Trust, the Trustee has the power to sell
Securities to pay such amounts. To the extent Securities are sold, the size of
the Trust will be reduced and the proportions of the types of Securities may
change. Such sales might be required at a time when Securities would not
otherwise be sold and might result in lower prices than might otherwise be
realized. Moreover, due to the minimum lot size in which Securities may be
required to be sold, the proceeds of such sales may exceed the amount necessary
for the payment of such fees and expenses.
 
                          ADMINISTRATION OF THE TRUST
 
RECORDS AND ACCOUNTS
 
    The Trustee will keep records and accounts of all transactions of the Trust
at its unit investment trust office at 101 Barclay Street, New York, New York
10286. These records and accounts will be available for inspection by Unit
Holders at reasonable times during normal business hours. The Trustee will
additionally keep on file for inspection by Unit Holders an executed copy of the
Indenture and Agreement together with a current list of the Securities then held
in the Trust. In connection with the storage and handling of certain Securities
deposited in the Trust, the Trustee is authorized to use the services of
Depository Trust Company. These services would include safekeeping of the
Securities, coupon-clipping, computer book-entry transfer and institutional
delivery services. The Depository Trust Company is a limited purpose trust
company organized under the Banking Law of the State of New York, a member of
the Federal Reserve System and a clearing agency registered under the Securities
Exchange Act of 1934.
 
DISTRIBUTION
 
   
    Dividends payable to the Trust as a holder of record of its Securities are
credited by the Trustee to an Income Account (after conversion into U.S. dollars
at the applicable exchange rate, in connection with payments on the Foreign
Securities), as of the date on which the Trust is entitled to receive such
dividends. Other receipts, including return of investment and gain and amounts
received upon the sale, pursuant to the Indenture and Agreement, of rights to
purchase other Securities distributed in respect of the Securities in the
Portfolio, are credited to a Principal Account (after conversion into U.S.
dollars at the applicable exchange rate, in
    
 
                                       24
<PAGE>
   
connection with payments on the Foreign Securities). Any distribution for each
Unit Holder as of a Record Date will be made on the next following Distribution
Date or shortly thereafter and shall consist of an amount approximately equal to
the dividend income per Unit, after deducting estimated expenses, if any, plus
such Holder's pro rata share of the distributable cash balance of the Principal
Account. Proceeds received from the disposition of any of the Securities which
are not used for redemption of Units will be held in the Principal Account to be
distributed on the Distribution Date following receipt of such proceeds. No
distribution need be made from the Principal Account if the balance therein is
less than $1.00 per 100 Units outstanding. A Reserve Account may be created by
the Trustee by withdrawing from the Income or Principal Accounts, from time to
time, such amounts as it deems requisite to establish a reserve for any taxes or
other governmental charges that may be payable out of the Trust. Funds held by
the Trustee in the various accounts created under the Indenture are non-interest
bearing to Unit Holders.
    
 
    On each Deferred Sales Charge Payment Date Securities will be sold pro rata
in an amount equal to $2.00 per 100 Units to pay the Deferred Sales Charge and
the proceeds will be distributed to the Sponsor.
 
   
    The Trustee will follow a policy that it will place securities acquisition
or disposition transactions with a broker or dealer only if it expects to obtain
favorable prices and executions of orders. Transactions in securities held in
the Trust are generally made in brokerage transactions (as distinguished from
principal transactions) and the Sponsor may act as broker therein and receive
commissions thereon if the Trustee expects thereby to obtain the most favorable
prices and execution. The furnishing of statistical and research information to
the Trustee by any of the securities dealers through which transactions are
executed will not be considered in placing securities transactions.
    
 
PORTFOLIO SUPERVISION
 
    The original proportionate relationship between the number of shares of each
Security in the Trust will be adjusted to reflect the occurrence of a stock
dividend, a stock split, merger, reorganization or a similar event which affects
the capital structure of the issuer of a Security in the Trust but which does
not affect the Trust's percentage ownership of the common stock equity of such
issuer at the time of such event. If the Trust receives the securities of
another issuer as the result of a merger or reorganization of, or a spin-off,
split-off or split-up by the issuer of a Security included in the original
portfolio, the Trust may hold those securities as if they were one of the
Securities initially deposited and adjust the proportionate relationship
accordingly for all future subsequent deposits. The Portfolio of the Trust is
not "managed" by the Sponsor or the Trustee; their activities described below
are governed solely by the provisions of the Indenture and Agreement. The
Sponsor may direct the Trustee to dispose of Securities upon failure of the
issuer of a Security in the Trust to declare or pay anticipated cash dividends,
institution of certain materially adverse legal proceedings, default under
certain documents materially and adversely affecting future declaration or
payment of dividends, or the occurrence of other market or credit factors that
in the opinion of the Sponsor would make the retention of such Securities in the
Trust detrimental to the interests of the Unit Holders. The Sponsor will direct
the Trustee to sell Securities to pay portions of the Deferred Sales Charge.
Except as otherwise discussed herein, the acquisition of any Securities for the
Trust other than those initially deposited and deposited in order to create
additional Units, is prohibited. The Sponsor is authorized under the Indenture
to direct the Trustee to invest the proceeds of any sale of Securities not
required for the redemption of Units in eligible money market instruments
selected by the Sponsor which will include only negotiable certificates of
deposit or time deposits of domestic banks which are members of the Federal
Deposit Insurance Corporation and which have, together with their branches or
subsidiaries, more than $2 billion in total assets, except that certificates of
deposit or time deposits of smaller domestic banks may be held provided the
deposit does not exceed the insurance coverage on the instrument (which
currently is $100,000), and provided further that the Trust's aggregate holding
of certificates of deposit or time deposits issued by the Trustee may not exceed
the insurance coverage of such obligations and U.S. Treasury notes or bills
(which shall be held until the maturity thereof) each of which matures prior to
the earlier of the next following Distribution Date or 90 days after receipt,
the principal thereof and interest thereon (to the extent such interest is not
used to pay Trust expenses) to be distributed on the earlier of the 90th day
after receipt or the next following Distribution Date.
 
                                       25
<PAGE>
    During the life of the Trust, the Sponsor, as part of its administrative
responsibilities, shall conduct reviews to determine whether or not to recommend
the disposition of Securities. In addition, the Sponsor shall undertake to
perform such other reviews and procedures as it may deem necessary in order for
it to give the consents and directions, including directions as to voting on the
underlying Securities, required by the Indenture and Agreement. For the
administrative services performed in making such recommendations and giving such
consents and directions, and in making the reviews called for in connection
therewith the Sponsor shall receive the portfolio supervisory fee referred to
under "Summary of Essential Information".
 
VOTING OF THE PORTFOLIO SECURITIES
 
    Pursuant to the Indenture and Agreement, voting rights with respect to the
Portfolio Securities and Replacement Securities, if any, will be exercised by
the Trustee in accordance with the Indenture or the directions given by the
Sponsor.
 
REPORTS TO UNIT HOLDERS
 
    With each distribution, the Trustee will furnish to Unit Holders a statement
of the amount of income and other receipts distributed, including the proceeds
of the sale of the Securities (including the sale of any Securities to pay
portions of the Deferred Sales Charge), expressed in each case as a dollar
amount per Unit.
 
    Within a reasonable period of time after the last Business Day in each
calendar year, but not later than February 15, the Trustee will furnish to each
person who at any time during such calendar year was a Unit Holder of record a
statement setting forth:
 
        1.  As to the Income and Principal Account:
 
           (a) the amount of income received on the Securities;
 
           (b) the amount paid for redemption of Units;
 
           (c) the deductions for applicable taxes or other governmental
       charges, if any, and fees and expenses of the Sponsor, the Trustee and
       counsel;
 
           (d) the deductions of portions of the Deferred Sales Charge;
 
           (e) the amounts distributed from the Income Account;
 
           (f)  any other amount credited or deducted from the Income Account;
       and
 
           (g) the net amount remaining after such payments and deductions
       expressed both as a total dollar amount and as a dollar amount per Unit
       outstanding on the last business day of such calendar year.
 
        2.  The following information:
 
           (a) a list of the Securities as of the last business day of such
       calendar year;
 
           (b) the number of Units outstanding as of the last business day of
       such calendar year;
 
           (c) the Unit Value (as defined in the Agreement) based on the last
       Evaluation made during such calendar year; and
 
           (d) the amounts actually distributed during such calendar year from
       the Income and Principal Accounts, separately stated, expressed both as
       total dollar amounts and as dollar amounts per Unit outstanding on the
       Record Dates for such distributions.
 
                                       26
<PAGE>
AMENDMENT
 
   
    The Indenture and Agreement may be amended from time to time by the Trustee
and the Sponsor or their respective successors, without the consent of any of
the Unit Holders (a) to cure any ambiguity or to correct or supplement any
provision contained therein which may be defective or inconsistent with any
other provision contained therein; (b) to change any provision thereof as may be
required by the Securities and Exchange Commission or any successor governmental
agency exercising similar authority; or (c) to make such other provision in
regard to matters or questions arising thereunder as shall not adversely affect
the interest of the Unit Holders; provided, that the Indenture and Agreement may
also be amended from time to time by the parties thereto (or the performance of
any of the provisions of this Indenture and Agreement may be waived) with the
expressed written consent of Holders of Units evidencing 51% of the Units at the
time outstanding under the Indenture and Agreement for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
the Indenture and Agreement or of modifying in any manner the rights of the Unit
Holders; provided, further however, that the Indenture and Agreement may not be
amended (nor may any provision thereof be waived) so as to (1) increase the
number of Units issuable in respect of the Trust above the aggregate number
specified in Part II of the Agreement or such lesser amount as may be
outstanding at any time during the term of the Indenture except as the result of
the deposit of Additional Securities, as therein provided, or reduce the
relative interest in the Trust of any Unit Holder without his consent, (2)
permit the deposit or acquisition thereunder of securities or other property
either in addition to or in substitution for any of the Securities except in the
manner permitted by the Trust Indenture as in effect on the date of the first
deposit of Securities or permit the Trustee to engage in business or investment
activities not specifically authorized in the Indenture and Agreement as
originally adopted or (3) adversely affect the characterization of the Trust as
a grantor trust for federal income tax purposes.
    
 
TERMINATION
 
   
    The Indenture and Agreement provides that the Trust will be liquidated
during the Liquidation Period as set forth under "Summary of Essential
Information" and terminated at the end of such period. Additionally, if the
value of the Trust as shown by any Evaluation is less than forty percent (40%)
of the value of the Securities deposited in the Trust on the Date of Deposit and
thereafter, the Trustee will, if directed by the Sponsor in writing, terminate
the Trust. The Trust may also be terminated at any time by the written consent
of Unit Holders owning 51% or more of the Units then outstanding. Unit Holders
will receive their final distributions (that is, their pro rata distributions
realized from the sale of Portfolio Securities plus any other Trust assets, less
Trust expenses) according to their Election Instructions. The Election
Instructions will provide for the following distribution options: (1) cash
distributions; (2) distributions "in kind" available only to any Unit Holder
owning Units with a value of $500,000 or more; or (3) investment of the
distributions attributable to the Unit Holder in units of a subsequent series of
the Dean Witter Select Equity Trust as designated by the Sponsor (the "New
Series") if such New Series is offered at such time (the "Rollover Option").
Unit Holders who do not tender properly completed Election Instructions to the
Trustee will be deemed to have elected a cash distribution.
    
 
   
    CASH OR "IN KIND" DISTRIBUTIONS. Unit Holders holding Units with a value of
less than $500,000 will receive distributions in respect of their Units at
termination solely in cash. Unit Holders holding Units with a value of $500,000
or more may indicate to the Trustee that they wish to receive termination
distributions "in kind", by returning to the Trustee properly completed Election
Instructions distributed by the Trustee to such Unit Holders of record 45 days
prior to the Termination Date. The Trustee will duly honor such election
instructions received on or before the In Kind Distribution Date. Such Unit
Holder will be entitled to receive whole shares of each of the underlying
Portfolio Securities and cash from the Principal Account equal to the fractional
shares to which such tendering Unit Holder is entitled. A Unit Holder receiving
distributions of Securities "in kind" may incur brokerage and odd-lot costs in
converting Securities so received into cash and may incur expenses in connection
with the delivery of foreign securities. The Trustee will transfer the foreign
securities to be delivered in kind to the foreign custody account of, and for
disposition in accordance with the instructions of, the Unit Holder.
    
 
                                       27
<PAGE>
   
    THE ROLLOVER OPTION. A Unit Holder may elect to invest the distributions
attributable to the Unit Holder in units of a New Series subject only to the
deferred sales charge of the New Series. It is expected that the terms of the
New Series will be substantially the same as the terms of the Trust described in
this Prospectus, and that similar options to invest in a subsequent series of
the Trust will be exercisable as respects termination distributions from each
New Series of the Trust approximately one year after that New Series' creation.
The availability of this option does not constitute a solicitation of an offer
to purchase Units of a New Series or any other security. A Unit Holder's
election to exercise this option will be treated as an indication of interest
only. At any time prior to the purchase by a Unit Holder of units of a New
Series, such Unit Holder may change his investment strategy and receive, in
cash, the proceeds of the sale of the Securities.
    
 
    METHOD OF SECURITIES DISPOSAL. The Trustee will begin to sell the remaining
Securities held in the Trust on the next business day following the In-Kind
Date. Since the Trust is not managed, Securities in the Portfolio must be sold
in accordance with the Indenture, which provides for sales over a period of days
or on any one day during the Liquidation Period set forth in the "Summary of
Essential Information". Daily proceeds of such sales will be deposited into the
Trust, will be held in a non-interest bearing account until distributed and will
be of benefit to the Trustee. The sales of Portfolio Securities may tend to
depress the market prices for such Securities and thus reduce the proceeds
available to Unit Holders. The Sponsor believes that gradual liquidation of
Securities during the Liquidation Period may mitigate negative market price
consequences stemming from the trading of large volumes of Securities over a
short period of time. There can be no assurance, however, that such procedures
will effectively mitigate any adverse price consequences of heavy volume trading
or that such procedures will produce a better price for Unit Holders than might
have been obtained had all the Securities been sold on one particular day during
the Liquidation Period.
 
    The Trustee will, after deduction of brokerage charges and costs incurred in
connection with the sale of Securities, any fees and expenses of the Trust and
payment into the Reserve Account of any amount required for taxes or other
governmental charges that may be payable by the Trust, distribute to each Unit
Holder, upon surrender for cancellation of its Certificate, if any, after due
notice of such termination, such Unit Holder's pro rata share in the Income and
Principal Accounts. The sale of Securities in the Trust upon termination may
result in a lower amount than might otherwise be realized if such sale were not
required at such time. For this reason, among others, the amount realized by a
Unit Holder upon termination may be less than the amount paid by such Unit
Holder for Units.
 
   
    Section 17(a) of the Investment Company Act of 1940 restricts purchases and
sales between affiliates of registered investment companies and those companies.
Pursuant to a recent exemptive order, each terminating Select Global 30
Portfolio Series can now sell securities to the next Series if those securities
will be contained in the portfolio of such next Series. The exemption will
enable each Series to eliminate commission costs on these transactions. The
price for those securities will be the closing sale price on the sale date on
the exchange where the securities are principally traded, as certified and
confirmed by the Trustee of each Series.
    
 
                       RESIGNATION, REMOVAL AND LIABILITY
 
REGARDING THE TRUSTEE
 
    The Trustee shall be under no liability for any action taken in good faith
in reliance on prima facie properly executed documents or for the disposition of
monies or Securities in the Trust, nor shall the Trustee be liable or
responsible in any way for depreciation or loss incurred by reason of the
disposition of any Securities by the Trustee. However, the Trustee shall be
liable for wilful misfeasance, bad faith or gross negligence in the performance
of its duties or by reason of its reckless disregard of its obligations and
duties under the Indenture and Agreement. In the event of a failure of the
Sponsor to act, the Trustee may act under the Indenture and Agreement and shall
not be liable for any such action taken by it in good faith. The Trustee shall
not be personally liable for any taxes or other governmental charges imposed
upon the Trust or in respect of the Securities or the interest thereon. The
 
                                       28
<PAGE>
Agreement also contains other customary provisions limiting the liability of the
Trustee and providing for the indemnification of the Trustee for any loss or
claim accruing to it without gross negligence, bad faith, wilful misconduct,
wilful misfeasance or reckless disregard of its duties and obligations under the
Agreement on its part.
 
    The Trustee or any successor may resign by executing an instrument in
writing, filing the same with the Sponsor and mailing a copy of such notice of
resignation to all Unit Holders then of record. Upon receiving such notice the
Sponsor will use its best efforts to appoint a successor Trustee promptly. If
the Trustee becomes incapable of acting or becomes bankrupt or its affairs are
taken over by public authorities, or upon the determination of the Sponsor to
remove the Trustee for any reason, either with or without cause, the Sponsor may
remove the Trustee and appoint a successor as provided in the Agreement. If
within 30 days of the resignation of a Trustee no successor has been appointed
or, if appointed, has not accepted the appointment, the retiring Trustee may
apply to a court of competent jurisdiction for the appointment of a successor.
The resignation or removal of a Trustee becomes effective only when the
successor Trustee accepts its appointment as such or when a court of competent
jurisdiction appoints a successor Trustee.
 
REGARDING THE SPONSOR
 
    The Sponsor shall be under no liability to the Trust or to Unit Holders for
taking any action or for refraining from any action in good faith or for errors
in judgment. Nor shall the Sponsor be liable or responsible in any way for
depreciation or loss incurred by reason of the disposition of any Security. The
Sponsor will, however, be liable for its own wilful misfeasance, wilful
misconduct, bad faith, gross negligence or reckless disregard of its duties and
obligations under the Agreement.
 
    If at any time the Sponsor shall resign under the Agreement or shall fail or
be incapable of performing its duties thereunder or shall become bankrupt or its
affairs are taken over by public authorities, the Agreement directs the Trustee
to either (1) appoint a successor Sponsor or Sponsors at rates of compensation
deemed reasonable by the Trustee not exceeding amounts prescribed by the
Securities and Exchange Commission, or (2) terminate the Trust Indenture and
Agreement and the Trust and liquidate the Trust. The Trustee will promptly
notify Unit Holders of any such action.

          This Reference Trust Agreement dated April 30, 1997
between DEAN WITTER REYNOLDS INC., as Depositor, and The Bank

Such provisions as are incorporated by reference constitute a

          In consideration of the premises and of the mutual
agreements herein contained, the Depositor and the Trustee
agree as follows:

                              I.

            STANDARD TERMS AND CONDITIONS OF TRUST

          Subject to the provisions of Part II hereof, all the
provisions contained in the Basic Agreement are herein
incorporated by reference in their entirety and shall be deemed
to be a part of this instrument as fully and to the same extent

     not used by the Trustee to purchase such Securities within
     the 90-day period following the first deposit of
     Securities in the Trust, shall be distributed to Unit
     Holders on the Distribution Date next following such 90-
     day period or such earlier date as the Depositor and the

     equal to the face amount of the letter of credit), to the
     extent  not used by the Trustee to purchase such
     Additional Securities within the 90-day period following
     the first deposit of Securities in the Trust, shall be
     distributed to Unit Holders on the Distribution Date next
     following such 90-day period or such earlier date as the
     Depositor and the Trustee determine".

          C.   Article III, entitled "Administration of Trust",
     Section 3.01 Initial Cost shall be amended as follows:

               (i)  the first part of the first sentence of
          Section 3.01 Initial Cost shall be amended to
          substitute the following language before the phrase
          "PROVIDED, HOWEVER":

                    "With respect to the Trust, the cost of the
               preparation, printing and execution of the
               Certificates, Indenture, Registration Statement
               and other documents relating to the Trust,
               Federal and State registration fees and costs,
               the initial fees and expenses of the Trustee,
               legal and auditing expenses and other out-of-
               pocket organizational expenses, to the extent
               not borne by the Sponsor, shall be paid by the
               Trust;"

          D.   The third paragraph of Section 3.05 is hereby
     amended to add the following sentence after the first
     sentence thereof:  "Depositor may direct the Trustee to
     invest the proceeds of any sale of Securities not required
     for the redemption of Units in eligible money market
     instruments selected by the Depositor which will include
     only negotiable certificates of deposit or time deposits
     of domestic banks which are members of the Federal Deposit
     Insurance Corporation and which have, together with their
     branches or subsidiaries, more than $2 billion in total
     assets, except that certificates of deposit or time
     deposits of smaller domestic banks may be held provided
     the deposit does not exceed the insurance coverage on the
     instrument (which currently is $100,000), and provided
     further that the Trust's aggregate holding of certificates
     of deposit or time deposits issued by the Trustee may not
     exceed the insurance coverage of such obligations and U.S.
     Treasury notes or bills (which shall be held until the
     maturity thereof) each of which matures prior to the
     earlier
<PAGE>

     of the next following Distribution Date or 90 days
     after receipt, the principal thereof and interest thereon
     (to the extent such interest is not used to pay Trust
     expenses) to be distributed on the  earlier of the 90th
     day after receipt or the next following Distribution
     Date."

          E.   The first sentence of each of Sections 3.10,
     3.11 and 3.12 is amended to insert the following language
     at the beginning of such sentence, "Except as otherwise
     provided in Section 3.13,".

          F.   The following new Section 3.13 is added:

          Section 3.13.  EXTRAORDINARY EVENT - SECURITY
     RETENTION AND VOTING.  In the event the Trustee is
     notified of any action 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 stock or
     securities held in the Trust, the Trustee shall take such
     action or refrain from taking any action, as appropriate,
     so as to insure that the securities are voted as closely
     as possible in the same manner and in the same general
     proportion as are the securities held by owners other than
     the Trust.  If stock or securities are received by the
     Trustee, with or without cash, as a result of any merger,
     reorganization, spin-off, split-off or split-up by the
     issuer of stock or securities held in the Trust, the
     Trustee at the direction of the Depositor may retain such
     stock or securities in the Trust.  Neither the Depositor
     nor the Trustee shall be liable to any person for any
     action or failure to take action with respect to this
     section.

          G.   Section 1.01 is amended to add the following
     definition:  (9) "Deferred Sales Charge" shall mean any
     deferred sales charge payable in accordance with the
     provisions of Section 3.14 hereof, as set forth in the
     prospectus for a Trust.  Definitions following this
     definition (9) shall be renumbered.

          H.   Section 3.05 is hereby amended to add the
     following paragraph after the end thereof:  On each
     Deferred Sales Charge payment date set forth in the
     prospectus for a Trust, the Trustee shall pay the account
     created pursuant to Section 3.14 the amount of the
     Deferred Sales Charge payable on each such date as stated
     in the prospectus for a Trust.  Such amount shall be
     withdrawn from the
<PAGE>

     Principal Account from the amounts therein designated for
     such purpose.

          I.   Section 3.06B(3) shall be amended by adding the
     following:  "and any Deferred Sales Charge paid".

          J.   Section 3.08 shall be amended by adding the
     following at the end thereof:  "In order to pay the
     Deferred Sales Charge, the Trustee shall sell or liquidate
     an amount of Securities at such time and from time to time
     and in such manner as the Depositor shall direct such that
     the proceeds of such sale or liquidation shall equal the
     amount required to be paid to the Depositor pursuant to
     the Deferred Sales Charge program as set forth in the
     prospectus for a Trust.

          K.   Section 3.14 shall be added as follows:

          Section 3.14.  DEFERRED SALES CHARGE.  If the
     prospectus for a Trust specifies a Deferred Sales Charge,
     the Trustee shall, on the dates specified in and as
     permitted by the prospectus, withdraw from the Income
     Account if such account is designated in the prospectus as
     the source of the payments of the Deferred Sales Charge,
     or to the extent funds are not available in that account
     or if such account is not so designated, from the
     Principal Account, an amount per Unit specified in the
     prospectus and credit such amount to a special, non-Trust
     account maintained at the Trustee out of which the
     Deferred Sales Charge will be distributed to the
     Depositor.  If the Income Account is not designated as the
     source of the Deferred Sales Charge payment or if the
     balances in the Income and Principal Accounts are
     insufficient to make any such withdrawal, the Trustee
     shall, as directed by the Depositor, either advance funds,
     if so agreed to by the Trustee, in an amount equal to the
     proposed withdrawal and be entitled to reimbursement of
     such advance upon the deposit of additional monies in the
     Income Account or the Principal Account, sell Securities
     and credit the proceeds thereof to such special
     Depositor's account or credit Securities in kind to such
     special Depositor's Account.  Such directions shall
     identify the Securities, if any, to be sold or distributed
     in kind and shall contain, if the Trustee is directed by
     the Depositor to sell a Security, instructions as to
     execution of such sales.  If a Unit Holder redeems Units
     prior to full payment of the Deferred Sales Charge, the
     Trustee shall, if so provided in the prospectus, on the
     Redemption Date, withhold from the Redemption Price
<PAGE>

     payment to such Unit Holder an amount equal to the unpaid
     portion of the Deferred Sales Charge and distribute such
     amount to such special Depositor's account or, if the
     Depositor shall purchase such Unit pursuant to the terms
     of Section 5.02 hereof, the Depositor shall pay the
     Redemption Price for such Unit less the unpaid portion of
     the Deferred Sales Charge.  The Depositor may at any time
     instruct the  Trustee to distribute to the Depositor cash
     or Securities previously credited to the special
     Depositor's account.

          L.   The following new Section 3.15 is added:

          Section 3.15.  FOREIGN EXCHANGE TRANSACTIONS;
     RECLAIMING FOREIGN TAXES.  (a) For any Trust holding
     Securities denominated in a currency other than U.S.
     dollars, the Depositor shall direct the Trustee with
     respect to the circumstances under which foreign exchange
     transactions are to be entered into and calculations under
     this Indenture are to be made, in order to convert amounts
     receivable in respect of the Securities in foreign
     currencies into U.S. dollars.

          (b)  The Trustee shall take such reasonable action as the
     Depositor shall direct or, if not so directed, use
     reasonable efforts to reclaim or recoup any amounts of non-
     U.S. tax paid by the Trust or withheld from income
     received by the Trust to which the Trust may be entitled
     as a refund.

          M.   The following paragraphs are inserted after the
     first paragraph in Section 4.01:

          "With respect to foreign securities, each Security
          listed on a securities exchange will be valued at
          the last closing sale price on the relevant stock
          exchange or if no such price exists at the closing
          offer price thereof.

          If the Trust holds securities denominated in a
          currency other than U.S. dollars, the
          evaluations shall be converted to U.S. dollars
          based, during the initial offering period, on
          the offering side of the relevant currency exchange
          rate, and subsequent to such period, on the bid side
          of the relevant exchange rate, including the
          cost of a forward foreign exchange contract in
          the relevant currency to correspond to the
          Trustee's settlement requirement for redemption
          requests as quoted to the Trustee by one or more
          banks designated by the Depositor, unless the
          Security is in the form of an American
          depositary share or receipt, in which case the
          evaluations shall be based upon the U.S. dollar
          prices in the market for American depositary
          shares or receipts (unless the Trustee deems
          such prices inappropriate as a basis for
          valuation)."

Gentlemen:

          We have acted as special counsel for you as Depositor
of the Dean Witter Select Equity Trust, Select Global Series 97-
3, Select Global 30 Portfolio 97-3 (the "Trust"), in connection
with the issuance under the Trust Indenture and Agreement,
dated September 30, 1993, and the related Reference Trust
Agreement, dated April 30, 1997 (such Trust Indenture and
Agreement and Reference Trust Agreement collectively referred
to as the "Indenture"), between you, as Depositor, and The Bank
of New York, as Trustee, of units of fractional undivided
interest in said Trust (the "Units") comprising the Units of
Dean Witter Select Equity Trust, Select Global Series 97-3,
Select Global 30 Portfolio 97-3.  In rendering our opinion
expressed below, we have relied in part upon the opinions and
representations of your officers and upon opinions of counsel
to Dean Witter Reynolds Inc.
<PAGE>

          Based upon the foregoing, we advise you that, in our
opinion, when the indenture has been duly executed and
delivered on behalf of the Depositor and Trustee and when the
Receipt for Units evidencing the Units has been duly executed
and delivered by the Trustee to the Depositor in accordance
with the Indenture, the Units will be legally issued, fully
paid and nonassessable by the Trust, and will constitute valid
and binding obligations of the Trust and the Depositor in
accordance with their terms, except that enforceability of
certain provisions thereof may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or other
similar laws affecting creditors generally and by general
equitable principles.

          We hereby consent to the filing of this opinion as an
exhibit to the Registration Statement (File No. 333-20279)
relating to the Units referred to above and to the use of our
name and to the reference to our firm in said Registration
