SUMMARY OF ESSENTIAL INFORMATION--(continued)

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

    (1)The number of Units will increase as the Sponsor deposits additional
Securities into the Trust. See "Unit Creation-- Deposit of Securities" in Part
B.


    (2)Unit Holders will bear Organization Costs, which include 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. At the close of
the initial offering period, Securities will be sold or cash will be used to
reimburse the Sponsor for its advancements towards Organization Costs.
Organization Costs per Unit have been estimated based on a Trust with $30
million of assets. If the assets of the Trust are less than $30 million, the
Organization Costs per Unit are likely to be greater than the estimate shown.


    (3)You will pay a maximum total sales charge of 2.90% of the Public Offering
Price. The sales charge has two components, an Initial Sales Charge and a
Deferred Sales Charge. The Initial Sales Charge is calculated by subtracting the
Deferred Sales Charge of $20 per 100 Units from the total sales charge. On the
date of this Summary of Essential Information, the Initial Sales Charge is $9.00
per 100 Units (0.90% of the Public Offering Price). The amount of the Initial
Sales Charge will change and may be more than $9.00 per 100 Units as the value
of the Securities changes after the Initial Date of Deposit. The Initial Sales
Charge is reduced if you purchase Units with a value of $25,000 or more. (See
"Public Offering of Units--Volume Discount"). You will pay a sales charge on all
of the Securities, including the Securities held to pay Organization Costs.


     To pay the Deferred Sales Charge, the Trustee will sell Trust assets equal
to $2.50 per 100 Units on each Deferred Sales Charge Payment Date (the last
business day of each month, over an 8 month period beginning January 31, 2000).
If you sell, redeem or exchange your Units before the last Deferred Sales Charge
Payment Date the proceeds payable to you will be reduced by the amount of any
unpaid Deferred Sales Charge. Units that you purchase through the Reinvestment
Program will be subject to the Deferred Sales Charge that remains at the time of
reinvestment (see "Reinvestment Program").


    (4)This is the price as of the Initial Date of Deposit only and will change
on subsequent dates.

    (5)This is the price as of the Initial Date of Deposit only and will change
on subsequent dates. 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 brokerage costs of selling Securities
to meet redemptions, currently estimated at $1.25 per 100 Units.

An investor would pay the following expenses on a $10,000 investment,
 assuming an estimated operating expense ratio and organization cost
 of 0.512% and a 5% annual return on the investment throughout
 the periods...................................................................   $     341    $     858   $   1,401   $   2,880

The Example assumes all dividends and distributions will be reinvested and uses 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 5 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 rate of return may be more or less than those assumed for purposes of the Example.
</TABLE>


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

(a)  The Initial Sales Charge is actually the difference between 2.90% and the
     Deferred Sales Charge of $20.00 per 100 Units; it will exceed 0.90% if the
     Public Offering Price exceeds $1,000 per 100 Units.

     The Deferred Sales Charge is paid at a rate of $2.50 per 100 Units per
     month on each of the 8 Deferred Sales Charge Payment Dates, irrespective of
     the purchase or redemption price per Unit. If a Holder sells Units before
     all of these payments have been made, any unpaid Deferred Sales Charge will
     be deducted from the sales proceeds. If the Unit purchase price exceeds
     $1000 per 100 Units, the Deferred Sales Charge will be less than 2.00%; if
     the Unit purchase price is less than $1000 per 100 Units, the Deferred
     Sales Charge will exceed 2.00%.

(b)  Reinvested dividends will be subject only to the Deferred Sales Charge
     remaining at the time of reinvestment which, as described above, may be
     more or less than 2.00% of the Public Offering Price at the time of
     reinvestment (see "Reinvestment Program").

(c)  The estimates do not include the costs paid by the Trust of purchasing and
     selling Securities.

(d)  The fees accrue daily and are payable on each Distribution Date. The
     Sponsor estimates that dividends from the Securities (based on the last
     dividends actually paid) will be sufficient to pay the estimated expenses
     of the Trust. See: "Expenses and Charges". In addition to the Trustee's
     fee, brokerage costs which the Trust will pay to purchase Securities are
     currently estimated at $1.00 per 100 Units.

SUMMARY OF ESSENTIAL
INFORMATION--(continued)

    INVESTMENT NAME AND STRUCTURE: The Morgan Stanley Dean Witter Select Equity
Trust Select Turnaround Focus List Series 1999 (the "Trust")--a unit investment
trust composed of publicly-traded common stocks or contracts to purchase those
stocks (the "Securities").


    OBJECTIVE: To provide capital appreciation from an investment that seeks to
identify companies that have the potential to "turnaround" with respect to
future common stock price performance by investing in the twenty common stocks
in the Council of Institutional Investors* October 1999 "Focus List," which was
released by the Council on September 27, 1999. The Focus List consists of
companies identified by the Council as having underperformed in their industry
groups in recent periods. There is, however, no guarantee that the Trust will
achieve its objective. Income is not an objective of the Trust.


    INVESTMENT SUMMARY: The Portfolio consists of the 20 common stocks chosen by
the Sponsor, based on the Council of Institutional Investors' October 1999
"Focus List". The Council of Institutional Investors, founded in 1985, is an
organization of large pension funds, which seeks to address investment issues
that affect the size or security of plan assets. Its objectives are to encourage
member funds, as major shareholders, to take an active role in protecting plan
assets and to help members increase return on their investments. The Council
currently has over 100 pension fund members, whose assets exceed $1 trillion.
Each October since 1991, the Council has released a list of corporations that it
deems to be underperforming, known as the "Focus List".

    The Focus List is intended to identify companies that have been poor
performers relative to their particular industry group. The Focus List is
intended to be used as an educational tool by Council members, and many members
use the Focus List as a supplement to their own corporate governance activities.
- ------------------------
* The Council of Institutional Investors did not select these stocks for the
purpose of inclusion in the Trust Portfolio, and the Trust is not sponsored,
endorsed, sold or promoted by the Council. The Council makes no representation
regarding the advisability of investing in such a product.

    The list has been published annually since 1991. In selecting the Focus
List, the Council has used the following selection methods: From 1991 through
1993, the screening methods used included share price performance and analysis
of certain corporate governance activities and executive compensation. In those
years, the number of companies included in the Focus Lists were as follows:
1991, 16 companies; 1992, 25 companies; 1993, 57 companies.

    For the yearly periods beginning in 1994 through the present, the Focus
Lists have consisted of 20 companies, which were generally selected using share
price performance as described in "TRUST SECURITIES."

    There can be no assurance that the Council will continue to develop Focus
Lists in future years, or if it does continue to do so, that it will use the
same selection methods or select the same number of companies that it does
currently.

    Although the Trust is a one-year investment, the strategy is long-term.
Investors should consider reinvesting in successive trusts, if available, for at
least three to five years, to take advantage of the long-term strategy.
Reinvesting each year requires your payment of the deferred sales charge each
year.

    TRUST SECURITIES: The Portfolio Securities were chosen by the Sponsor and
consist of the October 1999 Focus List. To select the stocks for this October
1999 list, the Council used the following steps:

    - Identify all companies in the S&P 500 index whose total common stock
      returns (stock price appreciation plus dividends) underperformed their
      industry group median for the one-, three- and five-year periods ending
      July 30, 1999.

    - Of these, remove those that outperformed the S&P 500 index for the
      five-year period.

    - Rank the remaining companies based on the difference between the industry
      group's median five-year total return and the company's five-year total
      return (the returns deficit).

    - Select the 20 companies with the highest returns deficit.

    The common stock of the 20 companies are approximately equally dollar
weighted in the Portfolio of the Trust.

                                       v
<PAGE>
    Following the initial deposit, the Sponsor expects to deposit additional
Securities, contracts to purchase additional Securities together with a letter
of credit and/or cash with instructions to purchase additional Securities to
create Additional Units. To the extent practicable, the proportionate
relationship between the number of shares of each Security in the Portfolio will
be maintained.

    PORTFOLIO CHARACTERISTICS. The Portfolio of the Trust consists of twenty
issues of common stocks, issued by companies in the categories set forth below:

    RISK FACTORS: An investment in Units of the Trust should be made with an
understanding of the following risks associated with the Trust's fixed portfolio
of common stocks:

    Risks inherent in an investment in common stocks include:

    - price fluctuation,

    - volatility inherent in equity securities, and

    - dividends may fluctuate or not be paid at any time.

    There are 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 that stock. These rights are inferior to those of
creditors and holders of debt obligations or 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.
Equity markets have been at historically high levels and we cannot assure that
these levels will continue.

    Securities may appreciate or depreciate in value (or pay dividends)
depending on the full range of economic and market influences (both domestic and
international) affecting corporate profitability, the financial condition of
issuers and the prices of equity securities in general and the Securities in
particular. The value of a Unit may decline and when you sell or redeem your
Unit it may be worth less than what you paid for it. Securities may only be sold
for limited reasons, such as a material deterioration in the financial condition
of an issuer. During the life of the Trust, Securities will not be sold to take
advantage of market fluctuations.

    Additional Risk Factors. See also notes to "Schedule of Portfolio
Securities" and "The Trust--Risk Factors" in Part B.

    DISTRIBUTION: The Trustee will distribute net income on each Distribution
Date to holders of record on the immediately preceding Record Date as set forth
on page i above. If Securities are sold and the sales proceeds are not used to
redeem Units, the sales proceeds will be distributed to Unit Holders. Upon
termination of the Trust, the Trustee will distribute to each Unit Holder of
record its pro rata share of the Trust's assets, less expenses and less any
Deferred Sales Charge then payable. Unit Holders can elect to reinvest their
distributions automatically in units of a New Series, if offered by the Sponsor.
Units acquired through reinvestment upon termination will be subject only to a
deferred sales charge (see "Administration of the Trust--Termination").

    The Sponsor anticipates that dividends from the Securities will be
sufficient to:

    - pay expenses of the Trust and

    - after paying expenses, to make the periodic net income distributions to
      Unit Holders.

    This expectation is based on the last dividend actually paid by the
companies included in the Schedule of Portfolio Securities. (See: "Expenses and
Charges" and "Administration of the Trust--Distribution".)

                                       vi
<PAGE>
    PUBLIC OFFERING PRICE: The Public Offering Price per 100 Units is computed
after receipt of a purchase order on the basis of

    - the total value of the underlying Securities and

    - cash held by the Trust.

    The assets are reduced by Trust expenses and liabilities and then divided by
the number of Units outstanding times 100. A sales charge is then added. Further
details can be found on pages i and ii above, particularly footnote 3. (See
"Public Offering of Units--Public Offering Price".)

    Unit Holders acquiring units in any future series through an exchange or
rollover of units of a previous series of the Select Focus Turnaround Portfolio
Series will acquire such units subject only to the Deferred Sales Charge.
Investors desiring to invest in successive trusts at a reduced sales charge must
elect to do so.

    MARKET FOR UNITS: The Sponsor, although not obligated to do so, intends to
maintain a market for the Units. If this 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. The sale or redemption price will
be the then current Unit net asset value including deduction for any remaining
Deferred Sales Charge.


    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 generally over a 14 business day period. Unit Holders may elect
to receive shares in-kind. Cash 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 January 11, 2001. The Trustee
will benefit from holding the cash because it can earn interest on it during the
period.


    The amount realized by a Unit Holder upon termination may be less than the
amount paid by the Unit Holder. Sales of Securities in the Trust during the
period before termination and upon termination may be at a lower price than
might otherwise be realized if the sale were not required at that time. (See:
"Administration of the Trust--Distribution".)

    Because the Trust is not managed and the Securities can only be sold during
the Liquidation Period or under certain other limited circumstances described in
this prospectus, 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. To lessen
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 these procedures will
lessen 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 forty percent of the value of all of
the Securities at the time they are acquired by the Trust.

    LITIGATION AND LEGISLATION: The Sponsor does not know of any pending
litigation as of the initial date of deposit that might reasonably be expected
to have a material adverse effect on the Portfolio, although pending litigation
may have a material adverse effect on the value of Securities in the Portfolio.
In addition, at any time after the initial date of deposit, litigation may be
initiated on a variety of grounds, or legislation may be enacted, affecting the
Securities in the Portfolio or the issuers of the Securities. Changing
approaches to regulation, particularly with respect to the environment or with
respect to the petroleum or tobacco industry, may have a negative impact on
certain companies represented in the Portfolio. Future litigation, legislation,
regulation or deregulation may have a material adverse effect on the Portfolio
or may impair the ability of the issuers of the Securities to achieve their
business goals.

HISTORICAL STRATEGY HYPOTHETICAL PERFORMANCE

    The following table shows the performance of:

    - all of the stocks in the S&P 500 Index; and

    - an investment in the Focus List stocks each year.

    No actual trust generated the performance.

S&P 500* TOTAL RETURN:

    This return is the change in value of the S&P 500, an index of 500 stocks
compiled by Standard & Poor's, plus the dividend return for the year. These
returns shown are not guarantees of future performance and should not be used as
a predictor of returns to be expected in connection with a Portfolio. These
returns do not reflect sales charges, commissions, expenses or taxes.

FOCUS LIST TOTAL RETURN:

    This return is the change in value of a hypothetical investment in
approximately equal values of the Focus List stocks as of the close of the last
business day of the previous year ended September 30 plus the dividend return on
such stocks for the indicated periods.

    As noted under "INVESTMENT SUMMARY," the number of companies contained in
the Focus Lists and the methods employed to arrive at the Focus Lists have
evolved since the Council began assembling the Focus Lists in October, 1991. The
Council has eliminated certain subjective measures from its selection methods
and began to focus exclusively on the companies in the S&P 500 as its beginning
universe.

    In the years ended September 30, 1992 through September 30, 1994 the
hypothetical performance of the Focus Lists achieved an average annual return of
21.92% compared with 9.15% for a hypothetical investment in all of the stocks in
the S&P 500. In the years ended September 30, 1995 through September 29, 1999
the hypothetical performance of the Focus Lists achieved an average annual
return of 24.37%

- ------------------------
* "S&P-Registered Trademark- 500" is a registered trademark of the McGraw-Hill
Companies, Inc. The Trust is not sponsored, managed, sold or promoted by
Standard & Poor's.

compared with 25.31% for a hypothetical investment in all of the stocks in the
S&P 500. The hypothetical performance data reflects investments in approximately
equal values of the Focus Lists component stocks for each of the years shown
below.


    These returns shown reflect past performance of the Focus List stocks. They
are not guarantees of future performance and should not be used as a predictor
of returns to be expected in connection with a Trust. The actual returns of a
particular Trust or purchase of units of a Trust will vary from the hypothetical
Focus List strategy returns due to, among other things, timing differences and
actual Trust sales charges, expenses and commissions incurred in buying and
selling portfolio securities.

    The average annual return reflects a rate of growth per year (assuming
reinvestment of all dividends at the end of each period for the S&P 500) that a
hypothetical investment in all of the stocks in the S&P 500 and the Focus List
would have provided over the 8 year period. Only the Focus List figures reflect
Trust sales charges (the full sales charge in the first year; reduced rollover
sales charges thereafter), estimated expenses and quarterly reinvestment of
dividends, but does not reflect commissions incurred in buying and selling
portfolio securities or taxes. As indicated in the table, the Focus List
strategy underperformed a hypothetical investment in all of the stocks in the
S&P 500 Index in certain years and there can be no assurance that the portfolio
of the Trust will outperform a hypothetical investment in all of the stocks in
the S&P 500 Index over the life of the Trust.

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

(a) The aggregate value of the Securities represented by Contracts to Purchase
    listed under "Schedule of Portfolio Securities" 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". A $300,000
    irrevocable letter of credit drawn on Banque Nationale de Paris has been
    deposited with the Trustee.



(b) A portion of the Public Offering Price consists of Securities in an amount
    sufficient to pay for all or a portion of the costs incurred in establishing
    the Trust. The Sponsor will be reimbursed for the organization costs at the
    close of the initial offering period. Organization costs per unit have been
    estimated based on a Trust with projected total assets of $30 million. To
    the extent the assets of the Trust are less than $30 million, the
    organization costs may be less, although the per Unit amount may increase.
    If the assets of the Trust are more, the organization costs may be higher,
    although the per Unit amount may decrease.



(c) Represents the aggregate amount of mandatory distributions of $2.50 per 100
    Units per month payable on the last business day of each month from January
    31, 2000 through August 31, 2000. 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
    August 31, 2000, the remaining portion of the obligation 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".

(e) The maximum 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".

(1) All Securities are represented entirely by contracts to purchase entered
    into on September 29, 1999. Valuation of Securities by the Trustee was made
    on the basis of the closing sale price on the exchange where the security is
    listed, or on the last sale price, if not listed, at the Evaluation Time on
    September 29, 1999. The aggregate purchase price to the Sponsor for the
    Securities deposited in the Trust is $249,557.97. The Sponsor had a loss of
    $658.19 on the Initial Date of Deposit.

                               PROSPECTUS PART B

                 MORGAN STANLEY DEAN WITTER SELECT EQUITY TRUST

                                  INTRODUCTION

    Dean Witter Reynolds Inc. (the "Sponsor") and The Bank of New York (the
"Trustee") signed a Trust Indenture and Agreement and a related Reference Trust
Agreement that created this series of the Morgan Stanley Dean Witter Select
Equity Trust under the laws of the State of New York. Dean Witter Reynolds Inc.
is a principal operating subsidiary of Morgan Stanley Dean Witter & Co., a
publicly-held corporation.

                                   THE TRUST

OBJECTIVE AND SECURITIES SELECTION

    The objective of the Trust is:

    - to provide capital appreciation through an investment for approximately
      one year in a fixed portfolio of publicly-traded common stock.

    The Trust's Securities* were chosen in the manner described in the "Summary
of Essential Information" in Part A. There is, of course, no guarantee that the
Trust will achieve its objective.

SUMMARY DESCRIPTION OF THE PORTFOLIO

    The Trust consists of

        (1) the Securities listed under "Schedule of Portfolio Securities" as
    may continue to be held in the Trust;

        (2) any additional Securities and contributed cash that the Trust
    acquires and holds pursuant to the provisions of the Indenture;

        (3) undistributed income; and

        (4) undistributed cash realized from the disposition of Securities See:
    "Administration of the Trust".

    Because the Trust may sell certain Securities or reduce their percentage
under certain circumstances, and may acquire additional Securities from time to
time, the Trust is not expected to retain for any length of time its present
size and exact composition. See: "Unit Creation--Deposit of Securities" and
"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 increase the Trust's net asset value. Further, the
Trust may dispose of its Securities only under limited circumstances. See:
"Administration of the Trust--Portfolio Supervision".

    The Trust is an unmanaged, fixed portfolio of common stocks. After the
selection and the initial deposit of Securities, the Securities may no longer be
included in the Focus List.

- ------------------------
* The term "Securities" includes the initially deposited common stock, and any
  additional common stock or contracts to purchase additional common stock,
  subsequently acquired by the Trust pursuant to the Indenture and Agreement.
<PAGE>
    On and after the Initial Date of Deposit, however, the Sponsor expects to
deposit additional Securities and sell the additional Units created. These
deposits generally will reflect the stocks and their proportionate number of
shares in the Portfolio as of the Initial Date of Deposit. The creation and 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 that later date. The Securities were
selected irrespective of any buy or sell recommendation by the Sponsor or any
affiliate.

    There is no assurance that the Trust will declare or pay any distributions
in the future.

RISK FACTORS

    If you invest in Units of the Trust, you should understand the risks of an
investment in publicly-traded common stock. These risks include the risk that
the value of the Portfolio and hence of the Units will decline with decreases in
the market value of the Securities. See the risks described in the "Summary of
Essential Information" in Part A of the Prospectus, as well as those set forth
below.

    There is no assurance that the objective of the Trust will be met because
the Securities may rise or fall in value, and pay dividends, depending on the
full range of economic and market influences affecting:

    - corporate profitability,

    - the financial condition of issuers,

    - the prices of equity securities in general, and

    - the stocks that this Trust buys in particular.

    As the Sponsor creates Additional Units, all Units may represent more or
less of a particular Security, in terms of percentage of aggregate market value
of the portfolio. In addition, the brokerage fees incurred in purchasing
Securities with the 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 have his holdings diluted as a result of any brokerage fees.

Deferred Sales Charge

    On each Deferred Sales Charge Payment Date, the Trust will sell Securities
pro rata in an amount equal to $2.50 per 100 Units to pay the Deferred Sales
Charge. The Trust will distribute the proceeds of the sale to the Sponsor. As
the Trust sells Securities to pay the Deferred Sales Charge the Trust's assets
will be reduced and income per Unit may be reduced.

Fluctuating Security Value

    The value of the Securities, and therefore the value of Units, will
fluctuate and can decline, depending upon the full range of economic and market
influences which may affect the market value of the Securities. Certain risks
are inherent in an investment in equity securities, including (1) the risk that
the financial condition of one or more of the issuers of the Securities may
worsen; or (2) the general condition of the common stock market may weaken. In
either 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. Investors base these
perceptions upon such factors as:

    - expectations regarding domestic and foreign economic, monetary and fiscal
      policies;

                                       2
<PAGE>
    - inflation and interest rates;

    - currency exchange rates, economic expansion or contraction; and

    - global or regional political, economic or banking conditions.

    The Sponsor cannot predict the direction or scope of any of these factors.
Additionally, stock markets have recently been at historically high levels and
we cannot give any assurance that these levels will continue.

    Therefore, we can give no assurance that the Trust will effectively achieve
its objective over its one-year life. We can likewise give no assurance that
future portfolios selected using the same methodology as the Trust during
consecutive one-year periods will meet their objectives. The Trust is not
designed to be a complete equity investment program.

Payment Risks

    There are certain payment risks involved in owning common stocks. Risks
include those arising from the fact that the rights of holders of common and
preferred stocks to receive payments from the issuers of those stocks are
generally inferior to those of creditors of, or holders of debt obligations
issued by, these 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. Holders of common stocks such as those in the Portfolio also have a
right to participate in amounts available for distribution by the issuer only
after all other claims on the issuer have been paid or provided for. Neither
preferred nor common stocks represent an obligation or liability of the issuer.
Therefore, they do not offer any assurance of income or provide the degree of
protection of capital or debt securities.

    The issuance of debt securities, as compared with both preferred and common
stock, will create prior claims for payment of principal and interest in the
case of debt securities. The issuance of preferred stock, as compared with
common stock, will create prior claims for payment of dividends and liquidation
preferences in the case of preferred stock. These prior claims could adversely
affect (1) the ability and inclination of the issuer to declare or pay dividends
on its common stock or (2) the rights of holders of common stock with respect to
assets of the issuer upon liquidation or bankruptcy. Further, common stocks lack
a fixed principal amount and a maturity date but have values which are subject
to market fluctuations for as long as the common stocks remain outstanding.
Common stocks are thus unlike debt securities which typically have a stated
principal amount payable at maturity. 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 fluctuate over the
entire life of the Trust to values higher or lower than those on the Initial
Date of Deposit. The Sponsor may direct the Trustee to dispose of Securities
under certain specified circumstances (See "Administration of the
Trust--Portfolio Supervision"). However, the Trustee will not dispose of
Securities solely as a result of normal fluctuations in market value.

Possible Lack of Market

    We can give no assurance that a market will be made for any of the
Securities, that any market for the Securities will continue or that the
Securities in any markets made will be liquid. In addition, the Trust may be
restricted under the Investment Company Act of 1940 from selling Securities to
the Sponsor and its affiliates. The price at which the Securities may be sold in
connection with redemptions and the value of the Trust will be adversely
affected if trading markets for the Securities are limited or absent.

                                       3
<PAGE>
YEAR 2000 PROBLEM

    Like other investment companies, financial and business organizations and
individuals around the world, the Trust depends on the smooth functioning of
computer systems. The Trust could undergo difficulties if computer systems, such
as those used by the Sponsor or Trustee, do not properly process and calculate
date-related information and data concerning dates on or after January 1, 2000.
Many computer systems in use today cannot recognize the year 2000, but revert to
1900 or some other date, due to the manner in which dates were encoded and
calculated. That failure could have a negative impact on the handling of
securities trades, pricing, and Trust services, among other things. This is
commonly known as the "Year 2000 Problem." The Sponsor and Trustee are taking
steps that they believe are reasonably designed to address the Year 2000 Problem
with respect to computer systems that they use. At this time, however, there can
be no assurance that these steps will be sufficient to avoid any adverse impact
to the Trust, and interaction with other non-complying computer systems may have
an adverse effect on the Trust.

    The Year 2000 Problem is expected to affect business entities, which may
include issuers of the Trust's Securities, to a varying extent and based upon a
number of factors, including, but not limited to, industry sector and level of
technological sophistication. The Sponsor is unable to predict what impact, if
any, the Year 2000 Problem will have on issuers of the Securities contained in
the Trust.

Reimbursement Costs

    The Securities intended to be used to reimburse the Sponsor for the Trust's
organization costs may decrease in value during the initial offering period. To
the extent the proceeds from the sale of these Securities are insufficient to
repay the Sponsor for the organization costs, the Trustee will sell additional
Securities to allow the full reimbursement of the Sponsor. In that event, the
net asset value per Unit will be reduced by the amount of additional Securities
sold.

UNIT CREATION--DEPOSIT OF SECURITIES

    On the date that the Trust was created, the Sponsor deposited with the
Trustee certain securities and contracts and funds (represented by irrevocable
letter(s) of credit issued by major commercial bank(s)) for the purchase of the
Securities. The Securities were deposited at prices equal to their market value
as determined by the Trustee. The Sponsor may also deposit cash or a letter of
credit and instruct the Trustee to purchase Securities. The Sponsor created the
Trust simultaneously with the deposit of the Securities with the Trustee and the
execution of the Indenture and the Reference Trust Agreement. The Trustee then
immediately recorded the Sponsor as owner of the Units comprising the entire
ownership of the Trust.

    Through this 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 price
based on the market value of the Securities if they cannot be sold in the
secondary market which the Sponsor, although not obligated to, proposes to
maintain. A secondary market for Units is a market where Units are bought and
sold after their original issue. 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 by a Unit Holder of Units for redemption.
The Trustee has not participated in the selection of Securities for the Trust.
Neither the Sponsor nor the Trustee nor any of their affiliates will be liable
in way for any default, failure or defect in any Securities.

    With the deposit of the Securities in the Trust on the Initial Date of
Deposit, the Sponsor established a proportionate relationship between the number
of shares of each Security in the Portfolio. You may find the original
proportionate relationships on the Initial Date of Deposit in the "Schedule of
Portfolio Securities". The original proportionate relationships are subject to
adjustment under certain limited circumstances. See: "Administration of the
Trust--Portfolio Supervision". Under the Indenture and Agreement, the Sponsor
can deposit additional Securities and contracts to purchase additional
Securities together with a letter of credit or cash. The Sponsor may then give
instructions to the Trustee to purchase additional Securities in order to create
additional Units. Any such additional deposits made in the 90 day period
following the creation of the Trust will consist of securities

                                       4
<PAGE>
of the same issuers as those already in the Trust. These deposits 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. After the 90 day period
following the Initial Date of Deposit any deposit of additional Securities and
cash must replicate the portfolio exactly as it was immediately prior to that
deposit.

    Since the Sponsor deposits cash or a letter of credit in lieu of cash and
gives instructions to the Trustee to purchase additional Securities to create
Additional Units, 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. This is because the price of a Security fluctuates between the
time the cash is deposited and the time the cash is used to purchase the
Security.

    The Trustee may hold any cash deposited with instructions to purchase
Securities in an interest-bearing account. Any interest earned on such cash will
be the property of the Trust. Unit Holders will receive, as a distribution on
the earlier of (1) the first Distribution Date or (2) 90 days after the Initial
Date of Deposit:

    - any cash deposited with instruction to purchase Securities that is not
      used to purchase Securities, and

    - any interest not used to pay Trust expenses.

    The Sponsor may acquire large volumes of additional Securities for deposit
into the Trust over a short period of time. These 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. To do so, the Trust may enter 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
the Trust will bear. See "Summary of Essential Information". The Sponsor cannot
currently predict the actual market impact of the Sponsor's purchases of
additional Securities because it does not know the actual volume of Securities
to be purchased and the supply and price of such Securities.

    This prospectus may be used to continuously offer additional Units for sale
to the public. Units will be sold by the Sponsor 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 Sponsor
will reject the investor's order. The number of Units available may be
insufficient to meet demand. This may be 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. You will be deemed to have placed a new order for that number of Units
each day until that order is accepted. The Sponsor will execute your order, when
Units are available, at the Public Offering Price next calculated after the
Sponsor accepts your continuing order. You will, of course, be able to revoke
your 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. However, the Sponsor will accept indications of interest prior to the
effectiveness of the registration of the offering of Trust Units which become
orders upon effectiveness according to the order in which the Sponsor receives
the indications of interest.

    On the Initial Date of Deposit, each Unit represented the fractional
undivided interest in the Securities and net income of the Trust set forth under
"Summary of Essential Information". Afterwards, if you redeem any Units, the
amount of Securities in the Trust will decline, and the fractional undivided
interest represented by each remaining Unit in the balance of the Trust will
increase. However, if the Trust issues Additional Units, the Securities in the
Trust will increase by amounts allocable to such Additional Units and the
fractional undivided interest in the Trust will fall. Units will remain
outstanding until you or any Unit Holder, including the Sponsor, redeem them
upon tender to the Trustee, or until the termination of the Trust on the terms
specified in the Indenture and Agreement. Only the Trustee can redeem Units. You
can redeem your Units by tendering them to the Trustee, sell them to the Sponsor
if the Sponsor is willing to buy the Units or hold them until the Trust
terminates.

                            TAX STATUS OF THE TRUST

    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. Income received by the Trust will be treated as income of the Unit
Holders in the manner set forth below.

    Under the grantor trust rules of Sections 671-678 of the Internal Revenue
Code of 1986, as amended, each Unit Holder will be considered to be the owner of
a pro rata portion of each asset in the Trust. The total tax cost of each Unit
purchased solely for cash will equal the cost of Units, including the Initial
Sales Charge. A Unit Holder should determine the tax cost for each asset
represented by the Unit Holder's Units purchased solely for cash by allocating
the total cost 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 actually received by a Unit Holder upon termination of the
Trust or redemption of Units will be reduced by the Deferred Sales Charge and
the charge for organizational expenses. The relevant tax reporting forms sent to
a Unit Holder will also reflect the actual amounts paid to him, which will be
reduced by the Deferred Sales Charge and the charge for organizational expenses.
Accordingly, you should not increase the total cost for your Units by the amount
of the Deferred Sales Charge and the charge for organizational expenses.

    You as a Unit Holder will be considered to have received all of the
dividends paid on your pro rata portion of each Security when the Trust receives
the dividends including the portion of the dividend used to pay ongoing
expenses. In the case of a corporate Unit Holder, these dividends will qualify
for the 70% dividends received deduction for corporations to the same extent as
if the corporate Unit Holder held the dividend paying stock directly. An
individual Unit Holder who itemizes deductions will be entitled to an itemized
deduction for his pro rata share of fees and expenses paid by the Trust as if he
paid these fees and expenses directly. You are entitled to this deduction only
to the extent that this amount together with your other miscellaneous deductions
exceeds 2% of your 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 you or to your agent of your pro rata
share of the Securities in-kind upon redemption or termination of the Trust will
not be a taxable event to you. Your basis for these Securities will be equal to
your basis for the same Securities, previously represented by your Units, before
this distribution. The holding period for these Securities will include the
period during which you held the Units. You will have a taxable gain or loss,
which will be a capital gain or loss except in the case of a dealer, when you
dispose of these 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. These tax laws will treat the
income of the Trust as the income of the Unit Holders.

    In connection with the In-Kind Rollover Option set forth under
"Termination-In-Kind Rollover Option", you will not be taxed upon the receipt
in-kind from the Terminating Trust and the deposit in the New Trust of the
Duplicated Stocks. Your basis in these Duplicated Stocks will be your basis in
these Duplicated Stocks before the distribution from the Terminating Trust. The
holding period of these Duplicated Stocks will include the period during which
you held the Units. To the extent the Agent sells Securities received in-kind on
your behalf, you will have a taxable gain or loss, which will be a capital gain
or loss except in the case of a dealer. Your basis in non-Duplicated Stocks will
equal the purchase price paid by the Agent.

    If the proceeds that the Distribution Agent or the Trustee receives upon the
sale of an underlying Security exceed your adjusted tax cost allocable to the
Security disposed of, you will realize a taxable gain to the extent of that
excess. Conversely, if the proceeds that the Distribution Agent or the Trustee
receives upon the sale of an underlying Security are less than your adjusted tax
cost allocable to the Security disposed of, you will realize a loss for tax
purposes to the extent of that difference. However, if the Trustee reinvests
proceeds in a New Series in connection with an exchange or non In-Kind Rollover,
the Internal Revenue Service may not allow that loss for the underlying
securities in each trust which are substantially identical or if the purchase of
units of the New Series takes place less than thirty-one days after the sale of
the underlying Security.

    Under the Federal Tax Code, capital gain of individuals, estates and trusts
from Securities held for more than one year is subject to a maximum nominal tax
rate of 20%. That capital gain may, however, result in a disallowance of
itemized deductions and/ or affect a personal exemption phase-out. The maximum
lower capital gain rate of 20% will be unavailable to you for those Securities
which you have held for less than a year and a day at the time of sale. This
includes sales occasioned by mandatory or early termination of the Trust or the
exchange or rollover of Units.

    From time to time Congress considers proposals to reduce the rate of the
dividends-received deduction. This type of legislation, if enacted into law,
would reduce the after-tax return to investors who can take advantage of the
deduction.

    Foreign Unit Holders (including nonresident alien individuals, foreign
corporations, and foreign partnerships) not engaged in a U.S. trade or business
generally will be subject to a 30% withholding tax (or lower applicable treaty
rate) on dividend distributions.

    You should consult your tax advisor about how the above general information
applies to your own 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. If you are contemplating establishing a qualified retirement plan or IRA
or investing funds of such a plan or IRA in Trust units, you should consult your
tax advisor about the tax consequences of any action.

    Forms and arrangements for establishing qualified retirement plans and IRAs
are available from:

    - the Sponsor

    - other brokerage firms

    - other financial institutions

    Fees and charges for these plans and IRAs are not uniform and may vary from
time to time as well as from institution to institution.

                            PUBLIC OFFERING OF UNITS

PUBLIC OFFERING PRICE

    The Public Offering Price of the Units is calculated on each business day by
the following formula: the aggregate market value of the Portfolio Securities
and other Trust assets, as determined by the Trustee, next computed after
receipt of a purchase order is reduced by Trust liabilities and then divided by
the number of Units outstanding. The Units outstanding may be split to create
greater or fewer Units (a reverse split). The sales charge shown in "Summary of
Essential Information" is added to the net asset value per Unit. The Sponsor may
add to the Public Offering Price commissions and any other transactional costs,
if any, in connection with the deposit of additional Securities or contracts to
purchase additional Securities for the creation of Additional Units.

    After the Initial Date of Deposit, the Sponsor will include in the Public
Offering Price a proportionate share of cash 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.

    The Income Account is maintained by the Trustee to hold the income from the
Securities received by the Trust. In the event a stock is trading ex-dividend at
the time of deposit of additional Securities, the Sponsor will add to the Public
Offering Price an amount equal to the dividend that would be received if that
stock were to receive a dividend. The Public Offering Price per Unit is

                                       7
<PAGE>
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 Initial 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 Trust fees and expenses.

    A portion of the Public Offering Price also consists of cash or securities
in an amount sufficient to pay for all or a portion of the costs incurred in
establishing the Trust. These costs include:

    - the cost of the preparation of documents relating to the Trust

    - federal and state registration fees

    - the initial fees and expenses of the Trustee

    - legal expenses

    - any other out-of-pocket expenses.

    The Sponsor will receive the estimated organization costs as of the close of
the initial offering period.

    As more fully described in the Indenture, the Trustee determines the
aggregate market value of the Securities based on closing prices on the day it
makes the valuation as described under "Redemption--Computation of Redemption
Price". If there are no reported prices, the Trustee takes into account the same
factors referred to under "Redemption--Computation of Redemption Price".
Determinations are effective for transactions effected after the last preceding
determination.

SALES CHARGES

    The sales charge consists of an Initial Sales Charge and a Deferred Sales
Charge. To compute the Initial Sales Charge, deduct the Deferred Sales Charge of
$20.00 per 100 Units from the total sales charge. The Initial Sales Charge that
a Unit Holder pays may be more or less than the Initial Sales Charge on the
Initial Date of Deposit because of the fluctuation of the value of the
Securities from that on the Initial Date of Deposit. The Deferred Sales Charge
will initially be $20.00 per 100 Units but will decline each month by one
eighth. The Deferred Sales Charge will be paid through monthly payments of $2.50
per 100 Units per month commencing on the first Deferred Sales Charge Payment
Date shown on the Summary of Essential Information. The Deferred Sales Charge
will be paid with money acquired through the sale of Securities on each DSC
Payment Date or distribution of cash available for payment. To the extent that
the entire Deferred Sales Charge relating to your Units has not been paid at the
time of repurchase, redemption or exchange of the Units, we will deduct any
unpaid amount from the sale, redemption or exchange proceeds or in calculating
an in-kind distribution.

    For purchases of Units with a value of $25,000 or more, we will reduce the
Initial Sales Charge 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".
Unit Holders investing the proceeds of distribution from a previous terminating
Series of Morgan Stanley Dean Witter Select Equity Trust, upon purchase of Units
of the Trust, will be subject only to the Deferred Sales Charge on those Units.
If you acquire Units of the Trust in an exchange of units of a different unit
investment trust sponsored by the Sponsor you will not have to pay an initial
sales charge at the time of the exchange. However, these acquired Units will be
subject to the Deferred Sales Charge.

                                       8
<PAGE>
PUBLIC DISTRIBUTION

    The Sponsor directly and through dealers will distribute to the public, at
the Public Offering Price determined as provided above, Units issued on the
Initial Date of Deposit and Additional Units issued in additional deposits of
Securities. They may offer to the public unsold Units or Units acquired by the
Sponsor in the secondary market referred to below, 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. The Sponsor will sell Units to dealers
during the initial offering period at prices which reflect a concession of 70%
of the applicable sales charge, subject to change from time to time. In
addition, sales of Units may be made according to distribution arrangements with
certain banks and/or other entities. These banks and entities are subject to
regulation by the Office of the Comptroller of the Currency or by other bank
regulatory authorities and 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 that these customers pay is retained
by or remitted to these banks or entities in an amount equal to the amount
customarily received by an agent for acting in this capacity in connection with
the purchase of Units. The Glass-Steagall Act prohibits banks from underwriting
certain securities, including Units of the Trust. This Act, however, does permit
certain agency transactions. 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 register 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, the Sponsor presently intends to maintain, at
its expense, a secondary market for Units of this series of the Morgan Stanley
Dean Witter Select Equity Trust. The Sponsor also presently intends to
continuously offer to repurchase Units from Unit Holders at the Sponsor's
Repurchase Price. The Sponsor computes the Repurchase Price by adding:

    - the aggregate value of the Securities in the Trust, and

    - 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 the Sponsor deposited to purchase Securities or cash held in the
      Reserve Account

    - less expenses of the Trust, (includes Trustee fee, Sponsor fee, counsel's
      expenses and taxes, if any), and

    - less any remaining unpaid portion of the Deferred Sales Charge, and

    - less cash held for distribution to Unit Holders of record as of a date on
      or prior to the evaluation

and then dividing the result 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 estimated costs of liquidating the
Securities to meet redemption requests. The only sales charge incurred when a
Unit Holder sells Units back to the Sponsor is the payment of the unpaid portion
of the Deferred Sales Charge. The Sponsor may reoffer to the public any Units
repurchased by the Sponsor at the Sponsor's Repurchase Price. The reoffering
price will be the then-current Public Offering Price. The Sponsor will bear any
profit or loss resulting from the resale of these Units.

    The Sponsor may temporarily or permanently discontinue the repurchase of
Units of this series at the Sponsor's Repurchase Price if the supply of Units
exceeds demand or for any other business reason. In this 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. This profit or loss represents the
difference between the cost of the

                                       9
<PAGE>
Securities to the Sponsor and the cost of the Securities to the Trust. For a
description of this profit or loss and the amount of this 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 the Sponsor receives. If
the Sponsor receives cash from the Unit Holders prior to the settlement date for
purchase of Units or prior to the payment for Securities upon their delivery,
the Sponsor may use the cash in the Sponsor's business and may benefit from the
use of the cash.

    The Sponsor may also realize profits or sustain losses while maintaining a
secondary market in the Units. These profits or losses are the amount of any
difference between the prices at which the Sponsor buys Units and the prices,
including a sales charge, at which the Sponsor resells such Units 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. The Sponsor
may also discontinue the discount altogether.

    The sales charge of 2.90% of the Public Offering Price will decline as shown
on the following graduated scale for sales of at least $25,000 to any person
during the Initial Offering Period. The sales charge in the secondary market,
which will decline as shown on the following graduated scale, consists of an
Initial Sales Charge and the remaining portions of the Deferred Sales Charge.
The following scale assumes a Public Offering Price of $1,000.00 per 100 units:

</TABLE>

    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 above. For purchases
of $250,000.00 or more, the sales charge consists solely of a 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 your spouse or in the name of your child under age
21 are deemed for the purposes of the volume discount to be registered in your
name. 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.

                                   REDEMPTION

RIGHT OF REDEMPTION

    You may redeem one or more of your Units 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. You may
tender Units for redemption at any

                                       10
<PAGE>
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 you tender your Units to the Trustee for redemption
other than for the payment of any Deferred Sales Charge then due.

    On the third business day following the tender to the Trustee of Units to be
redeemed, you will be entitled to receive cash per Unit equal to the Redemption
Price per Unit. The Trustee will determine the Redemption Price as of the
Evaluation Time on the date of tender. The Evaluation Time is the close of the
market, generally 4:00 PM New York time.

    The "date of tender" is the date on which the Trustee receives Units.
However, for Units received after the Evaluation Time, the date of tender is the
next day on which the New York Stock Exchange is open for trading. These Units
will be deemed to have been tendered to the Trustee on that day for redemption
at the Redemption Price computed on that day.

    During the period in which the Sponsor maintains a secondary market for
Units, the Sponsor may repurchase any Unit presented for tender to the Trustee
for redemption no later than the close of business on the next Business Day
following that presentation.

REDEMPTION PROCEDURES

    In connection with each redemption the Sponsor will direct the Trustee to
redeem Units in accordance with the procedures set forth in either (1) or (2)
below.

    (1) The Trustee will redeem Units solely in cash for any one Unit Holder
tendering less than 25,000 Units. If you request redemption of at least 25,000
Units, the Sponsor may determine, at its discretion, to direct the Trustee to
redeem Units "in-kind" by distributing Portfolio Securities to you. 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. If you redeem Units "in-kind" you will
receive an amount and value of Trust Securities per Unit equal to the Redemption
Price Per Unit as determined at the Evaluation Time next following the tender as
set forth in this Prospectus under "Computation of Redemption Price" below. The
Trustee will hold the distribution "in-kind" for redemption of Units for your
account, and for disposition in accordance with your instructions. You will be
entitled to receive (1) whole shares of each of the underlying Portfolio
Securities, plus (2) cash equal to your pro rata share of the cash balance of
the Income and Principal Accounts and (3) cash from the Principal Account equal
to the fractional shares to which you are entitled. The Trustee, in connection
with implementing the redemption "in-kind" procedures outlined above, may make
any adjustments necessary to reflect differences between (1) the Redemption
Price of Units and (2) 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 you, the Trustee may sell Securities
in the Trust Portfolio in the manner discussed below. If you receive redemption
distributions of Securities "in-kind" you may incur brokerage costs and odd-lot
charges in converting those Securities into cash. The Trustee will assess
transfer charges to Unit Holders taking Securities "in-kind" according to its
usual practice.

    The portion of the Redemption Price which represents your interest in the
Income Account will 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, will be drawn from the Principal Account to
the extent that funds are available for that purpose. The Agreement authorizes
the Trustee to sell Securities in order to provide funds for redemption. To the
extent Securities are sold, the size of the Trust will decline. These 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
you receive may be more or less than the purchase price you originally paid. The
price difference will depend 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 these sales may exceed
the amount necessary for payment of Units redeemed. These excess proceeds will
be distributed pro rata to all remaining Unit Holders of record on the next
following Record Date.

                                       11
<PAGE>
    The Sponsor will supply to the Trustee a list of Securities to sell for
purposes of redeeming Units. If the Sponsor does not so instruct the Trustee,
the Trustee will select the Securities to sell so as to maintain, as closely as
practicable, the proportionate relationship between the number of shares of each
Security in the Trust.

    (2) The Trustee will redeem Units in-kind by an in-kind distribution to The
Bank of New York as the Distribution Agent. You will be able to receive in-kind
an amount per Unit equal to the Redemption Price per Unit as determined as of
the day of tender. In-kind distributions to Unit Holders will take the form of
whole shares of Securities. The Distribution Agent will distribute cash in lieu
of fractional shares. The whole shares, fractional shares and cash distributed
to the Distribution Agent will total an amount equal to the Redemption Price per
Unit.

    The Distribution Agent shall hold distributions in-kind upon the redemption
of Units. You shall be deemed to have designated the Distribution Agent as your
agent upon purchase of a Unit, for your account, and for disposition in
accordance with your instructions as follows:

    (i)  The Distribution Agent shall sell the In-Kind Distribution as of the
close of business on the date of tender or as soon as possible afterwards. The
Distribution Agent shall then remit to you, within seven calendar days, the net
proceeds of the sale, after deducting any brokerage commissions and transfer
taxes on the sale. However, you may request a distribution of the Securities as
set forth in paragraph (ii) below. The Distribution Agent may sell the
Securities through the Sponsor, and the Sponsor may charge brokerage commissions
on those sales.

    (ii) If you request distribution in-kind and tender more than 25,000 Units,
the Distribution Agent shall sell any portion of the In Kind Distribution
represented by fractional interests in shares in accordance with the above
information. The Distribution Agent shall then distribute (1) the net cash
proceeds plus (2) any other distributable cash to you together with (3)
certificates or book-entry credit to your account at the Sponsor of each of the
whole shares of Securities comprising the In-Kind Distribution.

    The 25,000 Unit threshold will not apply to redemptions in kind in
connection with a rollover or on an In-Kind Distribution Date in connection with
the termination of the Trust.

    The portion of the Redemption Price which represents your 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, will be withdrawn from the Principal Account
to the extent that funds are available for that purpose. To the extent
Securities are distributed in-kind to the Distribution Agent, the size of the
Trust will be reduced. Sales by the Distribution Agent 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 you receive may be more
or less than the purchase price you originally paid, depending on the value of
the Securities in the Portfolio at the time of redemption.

COMPUTATION OF REDEMPTION PRICE

    The Trust Evaluation per Unit is determined as of the Evaluation Time stated
under "Summary of Essential Information" above:

    - semiannually, on the last Business Day of each of the months of June and
      December,

    - on the day on which you tender any Unit of the Trust for redemption,
      unless you tender after the Evaluation Time on such day. In this case
      Tender shall be considered to have been made on the next day on which the
      New York Stock Exchange is open for trading.

    - on any other Business Day desired by the Sponsor or the Trustee.

                                       12
<PAGE>
I. To determine the Trust Evaluation per Unit, add:

    (1) The aggregate value of Securities in the Trust, as the Trustee
determines;

    (2) Cash on hand in the Trust, including dividends receivable on stocks
trading ex-dividend, other than money deposited to purchase Securities or money
credited to the Reserve Account;

    (3) All other assets of the Trust;

II. Then deduct from the resulting figure:

    (1) amounts representing any applicable taxes or governmental charges
payable by the Trust for the purpose of making an addition to the reserve
account,

    (2) amounts representing estimated accrued fees and expenses of the Trust,
including legal and auditing expenses,

    (3) amounts representing unpaid fees of the Trustee, the Sponsor and
counsel,

    (4) any remaining unpaid portion of the Deferred Sales Charge, and

    (5) cash held to redeem tendered Units and for distribution to Unit Holders
of record as of the Business Day prior to the Evaluation on the days or dates
set forth above;

III. Divide the result of the above computation by the total number of Units
outstanding on the date of this 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 estimated costs of liquidating the Securities to meet the
redemption.

    The Trustee shall determine the aggregate value of the Securities in good
faith in the following manner:

    - If the Securities are listed on one or more national securities exchanges,
      the Trustee shall base its valuation on the closing price on the exchange
      which is the principal market for these Securities. The exchange shall be
      the New York Stock Exchange if the Securities are listed there, unless the
      Trustee deems that price inappropriate as a basis for valuation.

    - If the Securities are not listed, or, if listed, if their principal market
      is a different exchange or there is no closing price on that exchange, the
      Trustee shall base such valuation on the closing price in the
      over-the-counter market, unless the Trustee deems that price an
      inappropriate basis for valuation.

    If there is no closing price, the Trustee shall use any of the following
methods which it deems appropriate:

    - on the basis of current bid prices of the Securities obtained from
      investment dealers or brokers, including the Sponsor, who customarily deal
      in securities comparable to those held by the Trust, or

    - if bid prices are not available for any of the Securities, on the basis of
      bid prices for comparable securities, or

    - by appraisal of the value of the Securities on the bid side of the market
      or by another appraisal method which the Trustee deems appropriate, or

    - by any combination of the above.

POSTPONEMENT OF REDEMPTION

    Your right of redemption may be suspended and the payment of the Redemption
Price per Unit to you may be postponed for more than seven calendar days
following a tender of Units for redemption

                                       13
<PAGE>
    - for any period during which the New York Stock Exchange, Inc. is closed,
      other than for customary weekend and holiday closings, or

    - 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

    - for any other periods that 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 suspension or postponement of
      this kind.

                                EXCHANGE OPTION


    Unit Holders of any Morgan Stanley Dean Witter Select Trust or any holders
of units of any other unit investment trust may elect to exchange any or all of
their Units for units of one or more of any series of the Morgan Stanley Dean
Witter Select Equity Trust that may from time to time be made available for such
exchange by the Sponsor, called the "Exchange Trusts".


    An exchange of this kind is implemented by a sale of Units and a purchase of
the units of an Exchange Trust. You may acquire these units at prices based on
reduced sales charges per unit. The purpose of these reduced sales charge is to
permit the Sponsor to pass on the cost savings resulting from such exchange to a
Holder who wishes to exchange units. The cost savings result from reductions in
time and expense related to advice, financial planning and operational expense
required for the Exchange Option.

    Each Exchange Trust has different investment objectives. You should read the
Prospectus for the applicable Exchange Trust carefully to determine the
investment objective before you exercise this option.

    This option will be available provided that (1) the Sponsor maintains a
secondary market in units of the applicable Exchange Trust and (2) units of the
applicable Exchange Trust are available for sale and are lawfully qualified for
sale in the state in which you are a resident. While the Sponsor presently
intends to maintain a secondary market for the units of Exchange Trusts, there
is no obligation on its part to do so. Therefore, we do not promise that a
market for units will in fact exist on any given date in which you wish to sell
or exchange Units, and we do not promise that the Exchange Option will be
available to any Unit Holder. The Sponsor reserves the right to modify, suspend
or terminate this option. The Sponsor will give sixty days notice before the
date of the termination of or a material amendment to the Exchange Option.
However, the Sponsor will not have to give notice in certain circumstances
approved by the Securities and Exchange Commission. In the event the Exchange
Option is not available to you at the time you wish to exercise that option, we
will immediately notify you and we will not take any action with respect to your
tendered Units without further instruction from you.

    You may make exchanges in whole units only. We will return any excess
proceeds from the surrender of your Units. Alternatively, you may make up any
difference between (1) the amount representing the Units being submitted for
exchange and (2) the amount representing the units being acquired up to the next
highest number of whole units. The full value of the Units, including any
make-up amount, will be subject to a sales charge.

    An exchange of Units pursuant to the Exchange Option will constitute a
"taxable event" under the Code. You will recognize a gain or loss at the time of
exchange. However, if you exchange 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 that
exchange. The IRS may seek to disallow the loss to the extent that (1) the
underlying securities in each Trust are substantially identical and (2) 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, you may notify the Sponsor that you wish to purchase
units of the Exchange Trust on the thirty-first day after the day of the sale of
the Units exchanged. The Sponsor will deposit the proceeds of

                                       14
<PAGE>
the Units surrendered in your brokerage account with the Sponsor. You may
withdraw the proceeds at any time. You may use cash from the account 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. You may
revoke the order to purchase by calling your financial advisor at any time
before the purchase on the thirty-first day.

    The Sponsor will purchase units at a price based upon the value of the Trust
per unit plus the applicable sales charge of 2.0%. However, we do not promise
that a market for units will exist on that 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.
The Sponsor will sell these units based on the value of the Trust per unit 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 the Sponsor does
not hold units in its inventory on the thirty-first day or if the Sponsor does
not create additional units or is unable to acquire units in the secondary
market, the Sponsor will not purchase units of the Exchange Trust and the cash
will remain in your account. If you exchange Units of one Trust for units of
another Trust, you should consult your tax advisor regarding the extent to which
that exchange results in the recognition of a loss for Federal and/or state or
local income tax purposes.

    To exercise the Exchange Option, you should notify the Sponsor of your
desire to acquire units of one or more of the Exchange Trusts. Upon the exchange
of Units of the Trust, we will deduct any Deferred Sales Charge balance from the
exchange proceeds. If units of the applicable outstanding series of the Exchange
Trust are available for sale at that time, you may select the series or group of
series for which the Units are to be exchanged. You 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. Units will be repurchased at a price based
upon the aggregate bid side evaluation per Unit of the Securities in the
Portfolio. We will sell units of the Exchange Trust to you 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 Morgan Stanley Dean Witter Select
Equity Trust, the applicable sales charge on that Trust will be the Deferred
Sales Charge of that Trust. The Deferred Sales Charge may be more or less than
2.0% of the Public Offering Price.

                              REINVESTMENT PROGRAM

    You may elect to automatically reinvest the distributions with respect to
your Units 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. You may participate in the Trust's reinvestment program by
filing a written notice of election with the Trustee. The Trustee must receive
your completed notice of election to participate in the Program at least ten
days prior to the Record Date applicable to any distribution in order for the
Program to be in effect for that distribution. You may modify or revoke
elections on similar notice.

    The Trustee will use these distributions, to the extent reinvested in the
Trust, at the direction of the Sponsor in one or both of the following manners:

                                       15
<PAGE>
    (1) The Trustee may use the distributions to purchase Units of this Series
of the Trust in the Sponsor's inventory. The purchase price payable by the
Trustee for each of these 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 Trustee will issue or credit the Units purchased to the
accounts of Unit Holders participating in the Program.

    (2) If there are no Units in the Sponsor's inventory, the Sponsor may
purchase additional Securities for deposit into the Trust as described above in
Part B. The Sponsor will deposit the additional Securities with any necessary
cash with the Trustee in exchange for new Units. The Trustee may then use the
distributions to purchase the new Units from the Sponsor. The price for these
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 purchased by the Trustee
will be issued or credited to the accounts of Unit Holders who participate in
the Program. The Sponsor may terminate the Program if it does not have
sufficient Units in its inventory or if it is no longer 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 created at the applicable price,
there remains a portion of the distribution which is not sufficient to purchase
a full Unit at that price, the Trustee will distribute that cash to Unit
Holders. The Trust will bear the cost of administering the reinvestment program.
Thus all Unit Holders will indirectly bear that cost.

                             RIGHTS OF UNIT HOLDERS

UNIT HOLDERS

    A Unit Holder is deemed to be a beneficiary of the Trust created by the
Indenture and Agreement. A Unit Holder is vested with all right, title and
interest in that Trust. As a Unit Holder, you may tender your Units to the
Trustee for redemption at any time.

    You are required to hold your Units in uncertificated form. The Trustee will
credit your account with the number of Units you hold. Units are transferable
only on the records of the Trustee upon presentation of evidence satisfactory to
the Trustee for each transfer. Any sums payable for taxes or other governmental
charges imposed upon these transactions must be paid by you and you must comply
with the formalities necessary to redeem Units.

CERTAIN LIMITATIONS

    The death or incapacity of any Unit Holder will not operate to terminate the
Trust. Death or incapacity will not entitle your legal representatives or heirs
to claim an accounting or to take any other action or proceeding in any court
for a partition or winding up of the Trust.

    Neither you nor any other 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. The only time you will have that
right is 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 that the Trustee or Sponsor takes.
You 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. The Trustee will vote these Securities in accordance with the
instructions of the Sponsor, if given. Otherwise the Trustee shall vote as it,
in its sole discretion, shall determine.

                                       16

                              EXPENSES AND CHARGES

    The Summary of Essential Information in Part A lists the estimated annual
Trust expenses. If actual expenses exceed the estimated amounts, the Trust will
bear the excess.

ORGANIZATION COSTS

    You and the other Unit Holders will bear all or a portion of the
organization costs and charges incurred in connection with the establishment of
the Trust. These costs and charges will include:

    - 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

    - legal and auditing expenses.

    The Sponsor will pay advertising and selling expenses at no cost to the
Trust.

TRUST FEES AND EXPENSES

    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. At no
time will the total amount the Sponsor receives for portfolio supervisory
services rendered to all series of the Morgan Stanley Dean Witter Select Equity
Trust in any calendar year exceed the aggregate cost to it of supplying those
services in that 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".
The Trust bears certain regular expenses of the Trust, including certain mailing
and printing expenses.

    The Sponsor's fee, the Trustee's fees and the Trust's 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 these fees may increase without your approval or the approval of
the other Unit Holders in proportion to increases under the classification "All
Services Less Rent" in the 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. If the actual expenses exceed the estimated
amounts, the excess expenses will be borne by the Trust.

OTHER CHARGES

    The Trust does or may incur the following additional charges as more fully
described in the Indenture and Agreement:

    - fees of the Trustee for extraordinary services

    - expenses of the Trustee, including legal and auditing expenses, and of
      counsel that the Sponsor designated

    - various governmental charges

                                       17
<PAGE>
    - expenses and costs of any action the Trustee takes to protect the Trust
      and the rights and interests of you and the other Unit Holders

    - indemnification of the Trustee for any loss, liability or expenses it
      incurred 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

    - 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

    - expenditures incurred in contacting Unit Holders upon termination of the
      Trust, and

    - brokerage commissions or charges incurred in connection with the purchase
      or sale of Securities.

PAYMENT

    The fees and expenses set forth in this Prospectus are payable out of the
Trust. When the Trustee pays them or when they are owed to the Trustee, they 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 these amounts. To
the extent that the Trustee sells Securities, the size of the Trust will decline
and the proportions of the types of Securities may change. These sales might be
required at a time when Securities would not otherwise be sold. These sales
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 these sales may exceed the amount necessary for the payment of these
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. Unit Holders may inspect these records and accounts 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 the Depository Trust
Company. These services would include safekeeping of the Securities,
coupon-clipping, computer book-entry transfer and institutional delivery
services.

DISTRIBUTION

    The Record Dates and the Distribution Dates are set forth in Part A of this
prospectus. See "Summary of Essential Information". The distributions will be an
amount equal to:

    - the Unit Holder's pro rata portion of the amount of dividend income
      received by the Trust, plus

    - proceeds of the sale of Portfolio Securities, including capital gains, not
      used for the redemption of Units, if any, less

    - the Trustee's fees and expenses and less the Sponsor's portfolio
      supervision fees.

                                       18
<PAGE>
    Distributions for the account of beneficial owners of Units registered in
"street name" that the Sponsor holds will be made to the investment account of
such beneficial owners maintained with the Sponsor. Whenever regulatory or tax
purposes require or whenever the Sponsor directs, the Trustee may make special
distributions on special distribution dates to Unit Holders of record on special
record dates that the Trustee declares.

    The Trustee credits dividends payable to the Trust as a holder of record of
its Securities to an Income Account, as of the date on which the Trust is
entitled to receive those dividends. The Trustee credits to a Principal Account
other receipts, including (1) return of investment and gain and (2) 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. The Trust will distribute the following to each Unit Holder as of a
Record Date on the next following Distribution Date or shortly thereafter.

    The Trustee will hold proceeds it receives from the disposition of any of
the Securities which are not used for redemption of Units in the Principal
Account until it distributes those proceeds on the Distribution Date following
their receipt. The Trustee does not need to make a distribution from the
Principal Account if its balance is less than $1.00 per 100 Units outstanding.
The Trustee may create a Reserve Account by withdrawing from the Income or
Principal Accounts, from time to time, amounts it deems necessary to establish a
reserve for any taxes or other governmental charges that may be payable out of
the Trust. Funds the Trustee holds in the various accounts created under the
Indenture are non-interest bearing to Unit Holders. The Trustee receives the
benefit of holding these funds, which are interest-bearing to it.

    On each Deferred Sales Charge Payment Date the Trustee will sell Securities
pro rata in an amount equal to $2.50 per 100 Units. The Trustee will use the
money it obtains to pay the Deferred Sales Charge and will distribute the
proceeds to the Sponsor.

    The Trustee will follow a policy of placing securities acquisition or
disposition transactions with a broker or dealer only if it expects to obtain
favorable prices and executions of orders. The Trustee generally makes
transactions in Securities held in the Trust in brokerage transactions, as
distinguished from principal transactions. In connection with the brokerage
transactions, the Sponsor may act as broker and receive commissions if the
Trustee expects to obtain the most favorable prices and execution. In placing
Securities transactions, the Trustee will not furnish statistical and research
information to the Trustee by any of the securities dealers through which the
Trustee executes transactions.

PORTFOLIO SUPERVISION

    The Trustee will adjust the original proportionate relationship between the
number of shares of each Security in the Trust to reflect:

    - the occurrence of a stock dividend

    - a stock split

    - a merger

    - a 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 that issuer at the time of that
      event.

    If the Trust receives the securities of another issuer as the result of (1)
a merger or reorganization of, (2) a spin-off, (3) a split-off or (4) a split-up
of 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

                                       19
<PAGE>
    - adjust the proportionate relationship accordingly for all subsequent
      deposits.

    The Sponsor or the Trustee does not "manage" the Portfolio of the Trust.
Only the provisions of the Indenture and Agreement govern their activities
described below. 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 those 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 those
deposited in order to create additional Units, is prohibited. The Indenture
authorizes the Sponsor 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. The Sponsor will select these instruments, which will include only
(1) negotiable certificates of deposit or (2) 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. However, the Trust may hold certificates of deposit or time deposits of
smaller domestic banks provided the deposit does not exceed the insurance
coverage on the instrument, which currently is $100,000. Also, the Trust's
aggregate holding of certificates of deposit or time deposits that the Trustee
issued may not exceed the insurance coverage of those obligations. U.S. Treasury
notes or bills, which the Trust shall hold until their maturity, must mature
prior to the earlier of the next following Distribution Date or 90 days after
receipt. The Trust shall distribute the principal and interest of each Treasury
note or bill, to the extent that interest is not used to pay Trust expenses, on
the earlier of the 90th day after receipt or the next following Distribution
Date.

    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 any other reviews and procedures it deems necessary in order for it to
give the consents and directions, including directions as to voting on the
underlying Securities, that the Indenture and Agreement require. The Sponsor
shall receive the portfolio supervisory fee referred to under "Summary of
Essential Information" for (1) performing the administrative services in making
those recommendations and (2) giving those consents and directions, and (3)
making the reviews called for.

VOTING OF THE PORTFOLIO SECURITIES

    The Indenture and Agreement states that the Trustee will exercise voting
rights with respect to the Portfolio Securities and Replacement Securities, if
any, in accordance with the Indenture or the directions that the Sponsor gives.

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. The statement shall express proceeds in each case
as a dollar amount per Unit.

                                       20
<PAGE>
    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 that calendar year was a Unit Holder of record a
statement setting forth:

        1.  As to the Income and Principal Account:

    - the amount of income received on the Securities;

    - the amount paid for redemption of Units;

    - the deductions for applicable taxes or other governmental charges, if any,
      and fees and expenses of the Sponsor, the Trustee and counsel;

    - the deductions of portions of the Deferred Sales Charge;

    - the amounts distributed from the Income Account;

    - any other amount credited or deducted from the Income Account; and

    - the net amount remaining after those payments and deductions expressed
      both as a total dollar amount and as a dollar amount per Unit outstanding
      on the last business day of that calendar year.

        2.  The following information:

    - a list of the Securities as of the last business day of that calendar
      year;

    - the number of Units outstanding as of the last business day of that
      calendar year;

    - the Unit Value (as defined in the Agreement) based on the last Evaluation
      made during that calendar year; and

    - 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
      those distributions.

AMENDMENT

    The Trustee and the Sponsor or their respective successors may amend the
Indenture and Agreement from time to time without the consent of any of the Unit
Holders

    - to cure any ambiguity or to correct or supplement any provision contained
      in the Indenture and Agreement which may be defective or inconsistent with
      any other provision;

    - to change any provision in the Indenture and Agreement as the Securities
      and Exchange Commission or any successor governmental agency exercising
      similar authority may require; or

    - to make another provision in regard to matters or questions arising in the
      Indenture and Agreement as shall not adversely affect the interest of the
      Unit Holders.

    The parties to the Indenture and Agreement may also amend that document from
time to time or they may waive the performance of any of the provisions of 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, if the
express written consent of Holders of Units evidencing 51% of the Units at the
time outstanding under the Indenture and Agreement is obtained. No party,
however, may amend the Indenture and Agreement, or waive may any provision
thereof, so as

                                       21
<PAGE>
to (1) increase the number of Units issuable in respect of the Trust above the
aggregate number specified in Part 2 of the Agreement or any lesser amount that
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 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 that 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 Initial Date of
Deposit and acquired afterwards, the Trustee will, if the Sponsor directs 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 final distributions according to their
Election Instructions. Final distributions are the Unit Holders pro rata
distributions realized from the sale of Portfolio Securities plus any other
Trust assets, less Trust expenses. The Election Instructions will provide for
the following distribution options: (1) cash distributions; (2) distributions
"in kind"; or (3) investment of the distributions attributable to your Units in
units of a subsequent new series of the Morgan Stanley Dean Witter Select Equity
Trust (the "New Series") as the Sponsor designates if the New Series is offered
at that time (the "Rollover Option"). Unit Holders who do not tender properly
completed Election Instructions to the Trustee will be considered to have
elected a cash distribution.

    CASH OR "IN-KIND" DISTRIBUTIONS. Unit Holders who hold Units at termination
will receive distributions from their Units in cash. Unitholders may, however,
indicate to the Trustee that they wish to receive termination distributions
"in-kind". To do so, return to the Trustee properly completed Election
Instructions, which the Trustee distributed to Unit Holders of record 45 days
prior to the Termination Date. You do not need any minimum number of Units to
elect an in-kind distribution. The Trustee will duly honor any election
instructions that it receives on or before the In-Kind Distribution Date. You
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 you are entitled. If you receive distributions of Securities "in-kind",
you may incur brokerage and odd-lot costs in converting those Securities into
cash. The Trustee will transfer the Securities to be delivered in-kind to your
account and for disposition in accordance with your instructions.

    NON IN-KIND ROLLOVER OPTION. You may elect to invest the distributions
attributable to your Units in units of a New Series subject only to the deferred
sales charge on the units of the New Series. We expect that the terms of the New
Series will be substantially the same as the terms of the Trust described in
this Prospectus. We also expect that similar options to invest in a subsequent
series of the Trust will be exercisable for 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. We will treat your
election to exercise this option as an indication of interest only. At any time
prior to your purchase of units of a New Series, you may change your investment
strategy and receive, in cash, the proceeds of the sale of the Securities.

    IN-KIND ROLLOVER OPTION. The Sponsor may offer Unit Holders the ability to
"roll over" their Units of the Trust for Units of a subsequent series as set
forth below. If this feature is offered, the following structure will be
implemented for those rollovers. Although the Sponsor may offer Unit Holders
this additional termination alternative, the Sponsor reserves the right in its
sole

                                       22
<PAGE>
discretion to decline to offer this alternative for any reason. If the Sponsor
determines to offer such alternative, it will notify Unit Holders, who will then
notify the Sponsor whether they wish to participate. This rollover will occur at
least 30 days before the scheduled termination of the Terminating Trust.

    If you wish to reinvest your interests in units of the Trust in Units of a
newly created series of Morgan Stanley Dean Witter Select Equity Trust, Select
Turnaround Focus List Series, you may do so by so advising your account
executive. This exchange will be effected by an in-kind redemption from the
Terminating Trust and subsequent in-kind deposit with the Trustee of the New
Trust, as follows:

    The Bank of New York will act as agent on your behalf in connection with the
creation of a Unit of the New Trust. The Agent will deposit the number and types
of securities constituting a Unit of the New Trust in kind in the New Trust.
Certain stocks contained in the Terminating Trust are likely to be included in
the portfolio of the New Trust. A Unit Holder in the Terminating Trust who
elects to receive his interest in the Terminating Trust in-kind and who wishes
to purchase Units in the New Trust by an in-kind contribution to the New Trust
would direct the Agent to carry out the transactions necessary to consummate the
in-kind deposit. The Agent would have the authorization to receive your in-kind
distribution from the Terminating Trust and to assemble and deposit, on your
behalf, the package of stocks needed to make up a Unit in the New Trust. This
assembly and deposit would include an in-kind contribution to the New Trust of
an appropriate amount of your interest in Duplicated Stocks. The Agent would
sell securities distributed in-kind from the Terminating Trust not required to
make up a Unit in the New Trust. The Agent would utilize the cash proceeds of
each sale to purchase the stocks, other than the Duplicated Stocks, necessary to
constitute a Unit of the New Trust. The proceeds of these sales will be reduced
and the cost of these purchases will increase by any applicable brokerage
commissions. If additional cash is necessary to purchase stocks, you would pay
that cash to the Agent. You would receive any cash not used to make up a Unit in
the New Trust. The Agent will sell fractional interests received from the
Terminating Trust. The Agent will use the cash proceeds of that sale to purchase
securities for deposit in the New Trust. If the Agent does not use the proceeds
for those purposes, the Agent will distribute them to you. Upon receipt of the
in-kind deposit, the Trustee will issue the appropriate number of Units in the
New Trust to the Unit Holder on whose behalf the Agent acted. If you acquire
units pursuant to an in-kind deposit into a New Trust from a Terminating Trust,
you will not be subject to an Initial Sales Charge on those units. You will be
subject only to a Deferred Sales Charge.

    We will also offer the ability to purchase Units of the New Trust by the
deposit of securities in-kind to persons who were not Unit Holders in a
Terminating Trust. Any such person may contribute whole shares in-kind to a New
Trust. He will be required to pay the Initial Sales Charge to the Sponsor in
connection with the in-kind purchase of Units. These Units will be subject to a
Deferred Sales Charge.

    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. The Indenture 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". The Trustee will deposit proceeds of these
sales into the Trust. The Trustee will hold those proceeds in a non-interest
bearing account to Unit Holders until distributed, and the Trustee will receive
benefit from these proceeds. The sales of Portfolio Securities may tend to
depress the market prices for these 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 these 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.

                                       23

    After (1) deducting brokerage charges and costs incurred in connection with
the sale of Securities and any fees and expenses of the Trust and (2) paying
into the Reserve Account any amount required for taxes or other governmental
charges that may be payable by the Trust, the Trustee will distribute to each
Unit Holder, after due notice of that termination, the Unit Holder's pro rata
share of 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 that sale were not required at that time. For this reason, among others, the
amount you may realize upon termination may be less than the amount you paid for
Units.

    The Division of Investment Management of the SEC believes that the rollover
option constitutes an "exchange offer", for the purposes of Section 11(c) of the
Investment Company Act of 1940, and would therefore be prohibited without an
exemptive order. The Sponsor has obtained an exemptive order under Section 11(c)
which it believes permits it to offer the rollover. There can be no assurance
that the SEC will concur with the Sponsor's position. Additional regulatory
approvals may be required.

                       RESIGNATION, REMOVAL AND LIABILITY

REGARDING THE TRUSTEE

    The Trustee is under no liability for:

    - any action taken in good faith in reliance on apparently properly executed
      documents or

    - for the disposition of cash or Securities in the Trust.

The Trustee is not liable or responsible in any way for depreciation or loss as
a result of the Trustee's disposition of any Securities. However, the Trustee is
liable for wilful misfeasance, bad faith or gross negligence in the performance
of its duties. The Trustee is also liable if it recklessly disregards 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. In that case, the Trustee will not be liable for any action taken by
it in good faith. The Trustee will not be personally liable for any taxes or
other governmental charges imposed upon the Trust or in respect of the
Securities or dividends. The 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 (1) gross or extreme
negligence, (2) bad faith, (3) wilful misconduct, (4) wilful misfeasance or (5)
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 instrument with the Sponsor and mailing a copy of that
notice of resignation to all Unit Holders then of record. Upon receiving that
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 if
public authorities take over its affairs, or if the Sponsor determines 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 the Sponsor has not appointed a successor
or, if appointed, it 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.

                                       24
<PAGE>
REGARDING THE SPONSOR

    The Sponsor will 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. Likewise, the Sponsor will not be liable or responsible in any way
for depreciation or loss resulting from the disposition of any Security. The
Sponsor will, however, be liable for (1) its own wilful misfeasance, (2) wilful
misconduct, (3) bad faith, (4) gross negligence or (5) reckless disregard of its
duties and obligations under the Agreement.

    If at any time the Sponsor (1) resigns under the Agreement or (2) fails or
is incapable of performing its duties under the Agreement or (3) becomes
bankrupt or (4) has its affairs taken over by public authorities, the Agreement
directs the Trustee to act. The Trustee will either (1) appoint a successor
Sponsor or Sponsors at rates of compensation that the Trustee finds reasonable
and which does not exceed 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
action.

          This Reference Trust Agreement dated September 29, 1999 between DEAN
WITTER REYNOLDS INC., as Depositor, and The Bank of New York, as Trustee, sets
forth certain provisions in full and incorporates other provisions by reference

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

          In consideration of the premises and of the mutual agreements herein

     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".

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

          Section 3.01 Initial Cost shall be amended to substitute the following
language:

          SECTION 3.01. INITIAL COST The costs of organizing the Trust and sale
     of the Trust Units shall, to the extent of the expenses reimbursable to the
     Depositor provided below, be borne by the Unit Holders, PROVIDED, HOWEVER,
     that, to the extent all of such costs are not borne by Unit Holders, the
     amount of such costs not borne by Unit Holders shall be borne by the
     Depositor and, PROVIDED FURTHER, HOWEVER, that the liability on the part of
     the Depositor under this section shall not include any fees or other
     expenses incurred in connection with the administration of the Trust
     subsequent to the deposit referred to in Section 2.01. Upon notification
     from the Depositor that the primary offering period is concluded, the
     Trustee shall withdraw from the Account or Accounts specified in the
     Prospectus or, if no Account is therein specified, from the Principal
     Account, and pay to the Depositor the Depositor's reimbursable expenses of
     organizing the Trust and sale of the Trust Units in an amount certified to
     the Trustee by the Depositor. If the balance of the Principal Account is
     insufficient to make such withdrawal, the Trustee shall, as di-


<PAGE>
                                       -3-


     rected by the Depositor, sell Securities identified by the Depositor, or
     distribute to the Depositor Securities having a value, as determined under
     Section 4.01 as of the date of distribution, sufficient for such
     reimbursement. The reimbursement provided for in this section shall be for
     the account of the Unitholders of record at the conclusion of the primary
     offering period and shall not be reflected in the computation of the Unit
     Value prior thereto. As used herein, the Depositor's reimbursable expenses
     of organizing the Trust and sale of the Trust Units shall include the cost
     of the initial preparation and typesetting of the registration statement,
     prospectuses (including preliminary prospectuses), the indenture, and other
     documents relating to the Trust, SEC and state blue sky registration fees,
     the cost of the initial valuation of the portfolio and audit of the Trust,
     the initial fees and expenses of the Trustee, and legal and other
     out-of-pocket expenses related thereto, but not including the expenses
     incurred in the printing of preliminary prospectuses and prospectuses,
     expenses incurred in the preparation and printing of brochures and other
     advertising materials and any other selling expenses. Any cash which the
     Depositor has identified as to be used for reimbursement of expenses
     pursuant to this Section shall be reserved by the Trustee for such purpose
     and shall not be subject to distribution or, unless the Depositor otherwise
     directs, used for payment of redemptions in excess of the per-Unit amount
     allocable to Units tendered for redemption.

          E. 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 ex-


<PAGE>
                                       -4-

     ceed 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."

          F. 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,".

          G.   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.

          H. 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.

          I. 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


<PAGE>
                                       -5-

     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
     Principal Account from the amounts therein designated for such purpose.

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

          K. 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.

          L.   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


<PAGE>
                                       -6-

     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 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.

          M. Reference to "Dean Witter Select Equity Trust" is replaced by
     "Morgan Stanley Dean Witter Select Equity Trust".

                                       II.
