                 SUMMARY OF ESSENTIAL INFORMATION--(continued)

   
    THE  TRUST--The  Dean  Witter  Select  Equity  Trust  Select  10  Industrial
Portfolio  94-4  (the  "Trust")   is  a  unit   investment  trust  composed   of
publicly-traded  common  stocks  or  contracts  to  purchase  such  stocks  (the
"Securities").  The  objectives  of  the   Trust  are  to  provide  income   and
above-average  growth potential through  investment in the  ten common stocks in
the Dow Jones Industrial Average having the highest dividend yield (the  "Select
10")  as of the Date of Deposit. The companies represented in the Trust are some
of the most  well-known and highly  capitalized companies in  America. Many  are
household  names. An investment in approximately equal values of the ten highest
yielding stocks in the  Dow Jones Industrial  Average for a  period of one  year
would  have, in most of the last 20 years, yielded a higher total return than an
investment in all  of the  stocks comprising  the Dow  Jones Industrial  Average
itself. The Select 10 Industrial Portfolio seeks to achieve a better performance
than  the  Dow Jones  Industrial Average.  Investment in  a number  of companies
having high  dividends relative  to their  stock prices  (usually because  their
stock  prices are depressed)  is designed to increase  the Trust's potential for
higher returns. The  Securities may appreciate  or depreciate in  value (or  pay
dividends)  depending  on  the  full range  of  economic  and  market influences
affecting corporate profitability,  the financial condition  of issuers and  the
prices  of  equity  securities  in general  and  the  Securities  in particular.
Therefore, there  is no  guarantee that  the  objectives of  the Trust  will  be
achieved.  On the initial Date of Deposit and thereafter, the Sponsor may, under
the  Indenture  and  Agreement,  deposit  additional  Securities,  contracts  to
purchase  additional Securities together with a letter of credit and/or cash (or
a letter of  credit in lieu  of cash) with  instructions to purchase  additional
Securities  in order to create Additional  Units while maintaining to the extent
practicable the proportionate relationship between the number of shares of  each
Security in the Portfolio.
    
   
    TERMINATION--The Trust will terminate approximately 1 year after the initial
Date of Deposit regardless of market conditions at that time. After this period,
the  Trust  will liquidate.  Unitholders of  2,500  units or  more may  elect to
receive shares in-kind.  Prior to  termination of  the Trust,  the Trustee  will
begin  to sell the Securities held  in the Trust over a  period not to exceed 10
consecutive business days (the "Liquidation Period"). Monies held upon such sale
of Securities will be held  uninvested in non-interest bearing accounts  created
by  the  Indenture  until distributed  pro  rata  to Unit  Holders  on  or about
        , 1995 and will be of benefit to the Trustee during such period.  During
the  life of the Trust, Securities will not  be sold to take advantage of market
fluctuations. Because the Trust  is not managed and  the Securities can only  be
sold  during the Liquidation Period or under certain other limited circumstances
described herein, the proceeds received from the sale of Securities may be  less
than  could  be  obtained if  the  sale had  taken  place at  a  different time.
Depending on the  volume of Securities  sold and  the prices of  and demand  for
Securities  at the time of such sale, the sales of Securities from the Trust may
tend to depress the market prices of such Securities and hence the value of  the
Units, thus reducing termination proceeds available to Unit Holders. In order to
mitigate  potential adverse  price consequences of  heavy volume  trading in the
Securities taking place over a  short period of time  and to provide an  average
market price for the Securities, the Trustee will follow procedures set forth in
the  Indenture to sell the Securities in an orderly fashion over a period not to
exceed the Liquidation Period. The Sponsor can give no assurance, however,  that
such  procedures will mitigate  negative price consequences  or provide a better
price for such Securities. The Trust may terminate earlier than on the Mandatory
Termination Date  if the  value of  the  Trust is  less than  the  Discretionary
Liquidation Amount set forth under "Administration of the Trust--Termination."
    

   
    DISTRIBUTION--The  Trustee will  distribute any  dividends and  any proceeds
from the disposition of Securities not used for redemption of Units received  by
the  Trust on          , 1995 and on or about        , 1995 to holders of record
on          , 1995 and  the Termination Date, respectively. Upon termination  of
the  Trust, the Trustee  will distribute to  each Unit Holder  of record its pro
rata share of the Trust's assets, less  expenses. The sale of Securities in  the
Trust  during the period prior to termination and upon termination may result in
a lower amount than might otherwise be  realized if such sale were not  required
at  such time  due to  impending or  actual termination  of the  Trust. For this
reason, among others, the amount realized by a Unit Holder upon termination  may
be  less than the amount paid by  such Unit Holder. (See: "Administration of the
Trust--Distribution".)
    

    The Sponsor anticipates that, based upon the last dividends actually paid by
the companies listed in the  "Schedule of Portfolio Securities", dividends  from
the  Securities will  be sufficient to  (i) pay  expenses of the  Trust and (ii)
after such payment, to make distributions  to Unit Holders as described  herein.
(See: "Expenses and Charges" and "Administration of the Trust--Distribution".)

   
    PUBLIC  OFFERING PRICE--The Public Offering Price  per 100 Units is computed
on the basis of the aggregate  value of the underlying Securities next  computed
after receipt of a purchase order plus cash on hand in the Trust, divided by the
number  of Units outstanding  times 100, plus  a sales charge  of 4.058% of such
evaluation per 100  Units (the  net amount invested);  this results  in a  sales
charge  of 3.90% of  the Public Offering  Price. The sales  charge of 3.90% will
decline over the life of the Trust in the manner described below. On January  1,
1995,  the  sales  charge  will  decline to  3.50%  (3.627%  of  the  net amount
invested). On April 1, 1995, it will  decline again to 2.50% (2.564% of the  net
amount  invested) and on April 1, 1995, it  will decline to 1.50% (1.523% of the
net amount invested). (See: "Public Offering of Units--Public Offering Price".)
    

    MARKET FOR UNITS--The  Sponsor, though not  obligated to do  so, intends  to
maintain a market for the Units. If such market is not maintained, a Unit Holder
will  be able to dispose of his Units  through redemption at prices based on the
aggregate value  of  the  underlying  Securities.  (See:  "Redemption".)  Market
conditions  may cause such prices to be greater or less than the amount paid for
Units.

    RISK FACTORS--SPECIAL CONSIDERATIONS--An  investment in Units  of the  Trust
should  be made with an understanding of  the risks inherent in an investment in
common stocks, including risks associated with the limited rights of holders  of
common  stock to receive  payments from issuers  of such stock;  such rights are
inferior to those  of creditors  and holders  of debt  obligations or  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

                                      iii
<PAGE>
should  also  be  aware that  the  value  of the  underlying  Securities  in the
Portfolio may fluctuate in accordance with changes in the value of common stocks
in general. Although there are certain risks of price volatility associated with
investment in  common stocks,  your  risk is  reduced  because your  capital  is
divided among 10 stocks from several different industry groups.

    The portfolio of the Trust is concentrated in Securities issued by companies
deriving  a substantial portion of their income from the sale of oil and related
products. In addition to the general risks associated with investment in  common
stocks,  investment in the oil industry  may pose additional risks including the
impact of the following on the value of Securities of oil companies: changes  in
demand   for  oil  products,  increased   competition  among  oil  companies,  a
substantial increase in the price of oil, a drop in production of oil, a decline
in the supply of oil,  price controls on oil and  oil products, an oil  embargo,
the  political  situation  in  oil-producing  countries,  domestic  and  foreign
government  taxes  or  controls  on  the  oil  industry,  domestic  and  foreign
environmental  regulations  affecting  the oil  industries'  ability  to operate
necessitating substantial expenditures by the oil companies, the cost of cleanup
and litigation  costs relating  to  oil spills  and other  environmental  damage
caused  by  an oil  company, volatility  of  oil prices  and the  development of
alternate sources  of fuel.  Each  of the  above may  affect  the value  of  the
Securities  in  the  portfolio.  The  Sponsor  cannot  predict  the  impact  the
above-stated risks may have on the Securities in the portfolio over the one year
life of the Trust.

   
    In connection with the deposit by the Sponsor of cash (or a letter of credit
in lieu of cash) with instructions to purchase additional Securities in order to
create Additional Units, to the extent  that the price of a Security  fluctuates
between the time the cash is deposited and the time the cash is used to purchase
the Security, Units may represent more or less of that Security and more or less
of  other Securities in the  Portfolio of the Trust.  In addition, the brokerage
fees incurred in purchasing Securities with such deposited cash will be borne by
the Trust.  Any  Unit  Holder who  purchased  Units  prior to  the  purchase  of
Securities with such deposited cash would experience dilution as a result of any
such brokerage fees.
    

    SPECIAL CHARACTERISTICS OF THE TRUST

    --SECURITIES  SELECTION.  The Trust  Portfolio  consists of  the  ten common
stocks in the Dow Jones Industrial Average ("DJIA") having the highest  dividend
yield  as of the Date  of Deposit. Dow Jones and  Company Inc. ("Dow Jones") has
not participated in any way in the creation of the Trust or in the selection  of
the  stocks included in  the Trust and  has not approved  any of the information
herein relating thereto. The yield for each stock was calculated by  annualizing
the  last  quarterly  ordinary  dividend declared  and  dividing  the annualized
dividend  by  the  market  value  of  the  stock.  Such  formula  (an  objective
determination) served as the basis for the Sponsor's selection of the ten stocks
in  the  Dow Jones  Industrial Average  having the  highest dividend  yield. The
philosophy is simple. The  Trust does not require  sophisticated analysis or  an
explanation  of complex investment strategies, just  the pure and simple concept
of buying a quality portfolio of stocks with the highest dividend yields of  the
stocks  in the  DJIA in  one convenient  purchase. The  Securities were selected
irrespective of any buy or sell recommendation by the Sponsor. Investing in DJIA
stocks with the highest dividend yields may be effective as well as conservative
because regular dividends  are common  for established  companies and  dividends
have accounted for a substantial portion of the total return on DJIA stocks as a
group.

    Investors should note that the above criteria were applied to the Securities
selected  for  inclusion in  the  Trust Portfolio  as  of the  Date  of Deposit.
Subsequent to the Date of Deposit, the  Securities may no longer rank among  the
ten  stocks in  the DJIA having  the highest  dividend yield, the  yields on the
Securities in  the portfolio  may change  or  the Securities  may no  longer  be
included in the DJIA. However, the Sponsor may, on and subsequent to the Date of
Deposit,  deposit additional  Securities which reflect  the Portfolio  as of the
Date of  Deposit, subject  to permitted  adjustments, and  sell such  additional
Units  created.  The sale  of  additional Units  and the  sale  of Units  in the
secondary market may  continue even  though the  Securities would  no longer  be
chosen  for deposit into the  Trust if the selection process  were to be made at
such later time.

    Simple strategies can  sometimes be  the most effective.  To outperform  the
market  is more difficult than just outperforming other asset classes. The Trust
seeks a higher total return than the DJIA by acquiring the ten common stocks  in
the  DJIA having the highest dividend yields on the Date of Deposit, and holding
them for  about one  year. Purchasing  a portfolio  of these  stocks through  an
investment  in the Trust as opposed to  one or two individual stocks may achieve
better overall performance and will  achieve diversification. There is only  one
investment decision instead of ten, and two distributions to the investor during
the  one-year life of the Trust instead of 40. An investment in the Trust can be
cost-efficient, avoiding  the  odd-lot  costs  of  buying  small  quantities  of
securities  directly. Investment  in a number  of companies  with high dividends
relative to their stock prices is designed to increase the Trust's potential for
higher returns.  The Trust's  return may  consist of  a combination  of  capital
appreciation and current dividend income.

THE DOW, HISTORICALLY SPEAKING

    The  first DJIA, consisting of  12 stocks, was published  in THE WALL STREET
JOURNAL in 1896. The list grew to 20 stocks in 1916 and to 30 stocks on  October
1,  1928.  Taking into  account a  number of  names changes,  9 of  the original
companies are still in the DJIA today.  For two periods of 17 consecutive  years
each,  there were no changes  to the list: March 14,  1939-July 1956 and June 1,
1959-August 6, 1976.

    The Dow Jones Industrial Average is comprised of 30 common stocks chosen  by
the editors of The Wall Street Journal as representative of the broad market and
of  American industry. The  companies are major factors  in their industries and
their stocks are widely held by individuals and institutional investors.

    Changes in  the components  are made  entirely by  the editors  of The  Wall
Street  Journal without consultation  with the companies,  the stock exchange or
any official agency. For the sake  of continuity, such changes are made  rarely.
Most  substitutions  have been  the result  of  mergers, but  from time  to time
changes may  be made  to achieve  a better  representation. Notwithstanding  the
foregoing,  Dow Jones expressly  reserves the right to  change the components of
the Dow Jones Industrial Average at any time for any reason.

    The Select 10  Industrial Portfolio  seeks to achieve  a better  performance
than  the Dow Jones  Industrial Average (DJIA) through  investment for about one
year in the ten common stocks in  the DJIA having the highest dividend yield  as
of  the Date of Deposit. In  most instances in the last  20 years, a strategy of
investing in approximately  equal values of  these stocks each  year would  have
yielded a higher total return than an investment in all the stocks which make up
the DJIA.

    The  returns shown above are not guarantees of future performance and should
not be used  as a predictor  of returns to  be expected in  connection with  the
Portfolio.  Such returns do not reflect  sales charges, commissions, expenses or
taxes. As indicated in the above  tables, the Select 10 underperformed the  DJIA
in  certain years and there can be no  assurance that the portfolio of the Trust
will outperform the DJIA over the life of the Trust.

    --PORTFOLIO CHARACTERISTICS.  The Portfolio  of the  Trust consists  of  ten
issues of Securities, all of which are common stocks, issued by companies in the
categories set forth below:

THE UNIT HOLDERS, SPONSOR AND TRUSTEE
DEAN WITTER SELECT EQUITY TRUST
SELECT 10 INDUSTRIAL PORTFOLIO 94-4
    

   
    We  have  audited  the  accompanying statement  of  financial  condition and
schedule of portfolio securities of the  Dean Witter Select Equity Trust  Select
10  Industrial Portfolio 94-4 as of       , 1994. These financial statements are
the responsibility of the Trustee. Our  responsibility is to express an  opinion
on these financial statements based on our audit.
    

   
    We  conducted  our  audit  in accordance  with  generally  accepted auditing
standards. Those standards require that we plan and perform the audit to  obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of an irrevocable letter of  credit and contracts for the  purchase
of  securities, as shown in the statement of financial condition and schedule of
portfolio securities as of       , 1994, by correspondence with The Bank of  New
York,  the Trustee. An  audit also includes  assessing the accounting principles
used and significant estimates  made by the Trustee,  as well as evaluating  the
overall  financial statement presentation. We believe  that our audit provides a
reasonable basis for our opinion.
    

   
    In our  opinion,  the  statement  of financial  condition  and  schedule  of
portfolio securities referred to above present fairly, in all material respects,
the  financial  position  of  the  Dean Witter  Select  Equity  Trust  Select 10
Industrial Portfolio  94-4 as  of         , 1994  in conformity  with  generally
accepted accounting principles.

    AN OPPORTUNITY TO INVEST FOR INCOME AND ABOVE-AVERAGE GROWTH POTENTIAL

    - PORTFOLIO SELECTION -- Investment in the 10 common stocks in the Dow Jones
      Industrial  Average having the  highest dividend yield (as  of the Date of

    - DIVERSIFICATION -- Risk is reduced because your investment is spread among

INVEST IN THE 10 HIGHEST YIELDING STOCKS
IN THE DOW JONES INDUSTRIAL AVERAGE FOR
AS LITTLE AS $1,000.

- ---------------------------------------------------------
THE SELECT EQUITY TRUSTS

       Achieving  financial  success  in  today's  dynamic  markets  depends  on
       selecting  the right  investment strategy.  As new  opportunities emerge,
       sparked by changing business trends, market strategies must be geared  to
       capitalize  on  them.  Because  such  opportunities  may  not  be  easily
       identified by individual investors, Dean Witter has developed the  Select
       Equity  Trusts  that  offer  investors a  simple  and  convenient  way to
       participate in the equity market.

- --------------------------------------------------------------------------------
PORTFOLIO SELECTION

       The Select 10 Industrial  Portfolio consists of the  10 common stocks  in
       the  Dow Jones Industrial Average having the highest dividend yield as of
       the Date of  Deposit. The  Trust is specifically  designed for  investors
       seeking income and above-average growth potential. Because the Trust is a
       fixed  portfolio of  preselected securities,  purchasers know  in advance
       what they are investing in.

- --------------------------------------------------------------------------------
SPECIAL CONSIDERATIONS--RISK FACTORS

       The risks of an investment in Units of the Trust include price volatility
       resulting from factors  affecting the  common stock  of the  issuer of  a
       portfolio  security in particular and the  equity markets in general. The
       risks associated with an  investment in common stock  of oil and  related
       products  issuers  is  also present  as  the  portfolio of  the  Trust is
       concentrated in the stock of such issuers.

- --------------------------------------------------------------------------------
DIVERSIFICATION

       Risk is reduced through the Trust because it allows you to participate in
       a diversified  portfolio  of stocks.  Although  there are  certain  risks
       associated with investment in common stocks, your risk is reduced because
       your  capital is divided among 10 stocks from various industry groups. It
       would be difficult for the average investor to achieve a comparable level
       of diversification, without  making a substantial  capital commitment  or
       incurring odd-lot charges.

- --------------------------------------------------------------------------------
REINVESTMENT OPTION

       Investors  may elect  to have  distributions automatically  reinvested in
       additional units of the Trust without a sales charge.

- --------------------------------------------------------------------------------
COST EFFECTIVE

       CONVENIENT PURCHASE PRICE/NO ODD-LOT PENALTIES
       Typically stocks purchased in amounts less than 100 shares are subject to
       odd-lot penalties. If  you were  to purchase 100  shares of  each of  the
       stocks in this portfolio, it would require a large commitment of capital.
       If  you were to purchase  smaller amounts of each  stock, you would incur
       odd-lot penalties  on many  of your  purchases. Our  convenient  purchase
       price  of approximately $10  per unit with a  minimum purchase of $1,000,
       allows you to invest  in all the stocks  in an affordable manner.  Volume
       discounts are available beginning on orders over $25,000.

    The Offering Features are a part of the prospectus and should be read in
                                  conjunction
                          with the entire prospectus.

- ---------------------------------------------------
FLEXIBILITY THROUGH EXCHANGE PRIVILEGES

       Investors  may elect, at any  time, to exchange these  units for units of
       another Dean Witter Select Trust at a reduced sales charge.

- --------------------------------------------------------------------------------
SHORT-TERM LIFE

       The Trust will terminate  in approximately one  year. After this  period,
       the  Portfolio will liquidate.  Unit Holders owning  at least 2,500 units
       may elect to  receive distributions in  respect of their  Units in  kind.
       Unit  Holders not so electing will receive cash. You may, of course, sell
       or redeem your Units prior to the Trust's termination.

- --------------------------------------------------------------------------------
EASY LIQUIDITY WITHOUT A FEE

       Although not  obligated to  do  so, Dean  Witter  intends to  maintain  a
       secondary  market for the resale of Units. All or a portion of your Units
       may be liquidated at any time, without charge. The price you receive will
       reflect market  conditions and  could  be more  or  less than  the  price
       originally paid.

- --------------------------------------------------------------------------------
RETIREMENT ACCOUNTS

       This  Trust may be  an attractive investment  vehicle for a self-directed
       IRA or self-directed self-employed retirement plan ("Keogh plan"). As  an
       income-and growth-oriented investment, it may be a suitable complement to
       achieve overall portfolio diversification.

- --------------------------------------------------------------------------------
EASE OF OWNERSHIP

       The  usual chores associated with individual ownership of stocks--keeping
       records, safekeeping of certificates, and more--are eliminated through  a
       single  investment in  the Trust.  You will  receive year-end information
       from the Trustee, including Federal income tax information.

    The Offering Features are a part of the prospectus and should be read in

                        DEAN WITTER SELECT EQUITY TRUST

                                  INTRODUCTION

    This series of the Dean Witter Select Equity Trust (the "Trust") was created
under  the laws  of the  State of  New York  pursuant to  a Trust  Indenture and
Agreement (the  "Indenture")  and  a  related  Reference  Trust  Agreement  (the
"Agreement") (collectively, the "Indenture and Agreement")*, between Dean Witter
Reynolds  Inc. (the  "Sponsor") and  The Bank of  New York  (the "Trustee"). The
Sponsor is  a principal  operating subsidiary  of Dean  Witter, Discover  &  Co.
("DWDC"),  a publicly-held corporation. (See:  "Sponsor".) The objectives of the
Trust are income  and above  average growth  potential through  investment in  a
fixed portfolio of Securities (the "Portfolio") of publicly-traded common stock.
There is no assurance that this objective will be met because the Securities may
appreciate or depreciate in value (or pay dividends) depending on the full range
of  economic  and  market  influences  affecting  corporate  profitability,  the
financial condition of issuers  and the prices of  equity securities in  general
and the Securities in particular.

   
    On  the date of creation  of the Trust (the  "Date of Deposit"), 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 such securities (collectively, the "Securities") at
prices equal to the market value of such Securities as determined by the Trustee
as of the Date of Deposit  and/or cash (or a letter  of credit in lieu of  cash)
with instructions to the Trustee to purchase such Securities. (See: "Schedule of
Portfolio Securities".) The Trust was created simultaneously with the deposit of
the  Securities with  the Trustee  and the  execution of  the Indenture  and the
Agreement. The Trustee then immediately delivered to the Sponsor certificates of
beneficial interest (the  "Certificates") representing the  units (the  "Units")
comprising  the  entire ownership  of the  Trust.  Through this  prospectus (the
"Prospectus"), the Sponsor is offering the Units, including Additional Units, as
defined below, for sale  to the public. The  holders of Certificates (the  "Unit
Holders")  will have the right to have their  Units redeemed at a price based on
the market value of  the Securities (the "Redemption  Value") if they cannot  be
sold  in  the secondary  market which  the Sponsor,  although not  obligated to,
proposes to maintain. In addition, the Sponsor may offer for sale, through  this
Prospectus, Units which the Sponsor may have repurchased in the secondary market
or  upon  the  tender  of  such  Units  for  redemption.  The  Trustee  has  not
participated in  the selection  of Securities  for the  Trust, and  neither  the
Sponsor  nor the Trustee will  be liable in any way  for any default, failure or
defect in any Securities.
    

   
    With the deposit of the Securities in the Trust on the Date of Deposit,  the
Sponsor established a proportionate relationship between the number of shares of
each Security in the Portfolio. (The original proportionate relationships on the
Date  of  Deposit are  set  forth in  "Schedule  of Portfolio  Securities".) The
original proportionate  relationships are  subject to  adjustment under  certain
limited   circumstances.   (See:   "Administration   of   the   Trust--Portfolio
Supervision".) The Sponsor  is permitted  under the Indenture  and Agreement  to
deposit  during  the  life of  the  Trust, additional  Securities,  contracts to
purchase additional Securities together with a letter of credit and/or cash  (or
a letter of credit in lieu of cash) with instructions to the Trustee to purchase
additional  Securities in order to create additional Units ("Additional Units").
Any such additional deposits  will be in amounts  which maintain, to the  extent
practicable,  the  original  proportionate relationship  between  the  number of
shares of each Security in the Portfolio. It may not be possible to maintain the
exact original  proportionate  relationship  because of,  among  other  reasons,
purchase  requirements, prices changes or unavailability of Securities. Any cash
deposited with instructions to  purchase Securities may be  held in an  interest
bearing  account by the  Trustee. Any interest  earned on such  cash will be the
property  of  the  Trust.  Any  cash  deposited  with  instruction  to  purchase
Securities  not used  to purchase  Securities and any  interest not  used to pay
Trust expenses will be distributed to Unit  Holders on the earlier of the  first
Distribution  Date or 90 days after the Date of Deposit. Additional Units may be
continuously offered  for  sale to  the  public  by means  of  this  Prospectus.
Subsequent  to the 90  day period following  the Date of  Deposit any deposit of
additional Securities and cash must exactly replicate the portfolio  immediately
prior  to  such deposit.  The Sponsor  may acquire  large volumes  of additional
Securities for  deposit  into  the Trust  over  a  short period  of  time.  Such
acquisitions  may  tend to  raise  the market  prices  of these  Securities. The
Sponsor cannot  currently predict  the  actual market  impact of  the  Sponsor's
purchases  of additional Securities, because the  actual volume of Securities to
be purchased and the supply and price of such Securities is not known.
    

    Units will be sold to investors  at the Public Offering Price next  computed
after  receipt of the investor's order to purchase Units, if Units are available
to fill orders on the day that that price is set. If Units are not available  or
are insufficient to fill the order, the investor's order will be rejected by the
Sponsor.  The  number of  Units  available may  be  insufficient to  meet demand
because of the Sponsor's  inability to or decision  not to purchase and  deposit
underlying  Securities  in  amounts  sufficient  to  maintain  the proportionate
numbers of shares of each Security  as required to create additional Units.  The
Sponsor  may, if unable to accept orders on  any given day, offer to execute the
order as soon as sufficient Units can be created. An investor who agrees to this
will be deemed to place a new order for that number of Units each day until that
order is accepted. The  investor's order will then  be executed, when Units  are
available,  at the Public  Offering Price next  calculated after such continuing
order is accepted. The investor will, of course, be able to revoke his  purchase
offer  at any time prior to acceptance  by the Sponsor. The Sponsor will execute
orders to purchase  in the  order it determines  that they  are received,  i.e.,
orders  received first will be filled first, except that indications of interest
prior to the effectiveness  of the registration of  the offering of Trust  Units
which  become orders upon effectiveness will  be accepted according to the order
in which the indications of interest were received.

* Reference is hereby made  to said Indenture and  Agreement and any  statements
  contained  herein are  qualified in their  entirety by the  provisions of said
  Indenture and Agreement.
<PAGE>
    On the  Date of  Deposit,  each Unit  represented the  fractional  undivided
interest  in the Securities and net income of the Trust set forth under "Summary
of Essential Information". Thereafter, if any Units are redeemed, the amount  of
Securities  in the Trust will be  reduced, and the fractional undivided interest
represented by  each  remaining  Unit  in  the balance  of  the  Trust  will  be
increased.  However, if Additional Units are  issued by the Trust, the aggregate
value of the Securities in the Trust  will be increased by amounts allocable  to
such  Additional Units and the fractional undivided interest in the balance will
be decreased. In both cases, the interest in the Trust Securities represented by
each Unit will remain  unchanged. Units will  remain outstanding until  redeemed
upon tender to the Trustee by any Unit Holder (which may include the Sponsor) or
until the termination of the Trust pursuant to the Indenture and Agreement.

                                   THE TRUST

SPECIAL CONSIDERATIONS--RISK FACTORS

    An  investment in Units of the Trust should be made with an understanding of
the risks  which  an investment  in  publicly-traded common  stock  may  entail,
including  the risk that the value of the  Portfolio and hence of the Units will
decline with decreases in the market value of the Securities. The Trust will  be
terminated and liquidated no later than the Mandatory Termination Date set forth
in the "Summary of Essential Information".

SUMMARY DESCRIPTION OF THE PORTFOLIO

    As  used herein, the  term "Common Stocks"  refers to the  common stocks (or
contracts to purchase such common stocks) (any such contracts to purchase common
stocks to  be accompanied  by  an irrevocable  letter  of credit  sufficient  to
perform  such contracts), initially  deposited in the  Trust and described under
"Schedule  of  Portfolio  Securities".   The  term  "Securities"  includes   any
additional  common  stock  or  contracts  to  purchase  additional  common stock
together with  the  corresponding  irrevocable letter  of  credit,  subsequently
acquired by the Trust pursuant to the Indenture and Agreement.

    An  investment in Units  of the Trust  should be made  with an understanding
that the value of the underlying  Securities, and therefore the value of  Units,
will  fluctuate, depending upon the full range of economic and market influences
which may affect the market value of such Securities. Certain risks are inherent
in an investment  in equity securities,  including the risk  that the  financial
condition  of one  or more of  the issuers of  the Securities may  worsen or the
general condition of the common stock market may weaken. In such case, the value
of the Portfolio  Securities and hence  the value of  Units may decline.  Common
stocks  are susceptible  to general stock  market movements and  to volatile and
unpredictable increases  and decreases  in  value as  market confidence  in  and
perceptions  of the issuers change from time to time. Such perceptions are based
upon varying reactions to  such factors as  expectations regarding domestic  and
foreign  economic, monetary and  fiscal policies, inflation  and interest rates,
currency exchange  rates,  economic  expansion or  contraction,  and  global  or
regional  political, economic or  banking crises. In  addition, investors should
understand that  there  are certain  payment  risks involved  in  owning  common
stocks,  including  risks  arising from  the  fact  that holders  of  common and
preferred stocks  have rights  to receive  payments from  the issuers  of  those
stocks  that are generally inferior to those of creditors of, or holders of debt
obligations issued  by, such  issuers.  Furthermore, the  rights of  holders  of
common stocks are inferior to the rights of holders of preferred stocks. Holders
of  common stocks  of the  type held in  the Portfolio  have a  right to receive
dividends only when, as  and if, and  in the amounts,  declared by the  issuer's
board  of directors and to participate  in amounts available for distribution by
the issuer only after all other claims on the issuer have been paid or  provided
for.  By  contrast,  holders  of  preferred stocks  have  the  right  to receive
dividends at  a  fixed rate  when  and as  declared  by the  issuer's  board  of
directors,  normally on a cumulative basis, but do not ordinarily participate in
other amounts available for distribution by the issuing corporation.  Cumulative
preferred  stock dividends must  be paid before common  stock dividends, and any
cumulative preferred stock dividend omitted is added to future dividends payable
to the holders  of such cumulative  preferred stock. Preferred  stocks are  also
entitled  to rights on liquidation  which are senior to  those of common stocks.
For these  reasons,  preferred  stocks  entail less  risk  than  common  stocks.
However,  neither  preferred  nor  common  stocks  represent  an  obligation  or
liability of the issuer and  therefore do not offer  any assurance of income  or
provide  the degree of protection of capital of debt securities. The issuance of
debt securities (as compared with both preferred and common stock) and preferred
stock (as compared with  common stock) will create  prior claims for payment  of
principal  and interest (in the  case of debt securities)  and dividends (in the
case of  preferred securities)  which  could adversely  affect the  ability  and
inclination of the issuer to declare or pay dividends on its common stock or the
rights  of holders  of common stock  with respect  to assets of  the issuer upon
liquidation or bankruptcy. Further, unlike debt securities which typically  have
a  stated principal amount payable  at maturity (which value  will be subject to
market fluctuations prior  thereto), or  preferred stocks  which typically  have
liquidation   preference  and  which  may  have  stated  optional  or  mandatory
redemption provisions, common stocks have neither a fixed principal amount nor a
maturity date and have  values which are subject  to market fluctuations for  as
long  as the common  stocks remain outstanding.  Additionally, market timing and
volume trading will also  affect the underlying  value of Securities,  including
the  Sponsor's  buying  of  additional Securities  and  the  Trust's  selling of
Securities during the  Liquidation Period. The  value of the  Securities in  the
Portfolio thus may be expected to fluctuate over the entire life of the Trust to
values higher or lower than those prevailing on the Date of Deposit. The Sponsor
may  direct  the  Trustee  to  dispose  of  Securities  under  certain specified
circumstances  (see  "Administration  of  the  Trust--Portfolio   Supervision").
However,  Securities  will not  be  disposed of  solely  as a  result  of normal
fluctuations in market value.

                                       2

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

OBJECTIVES AND SECURITIES SELECTION

    The  objectives of  the Trust are  (i) to  provide income and  (ii) to offer
above-average growth potential through an investment for approximately one  year
in a fixed diversified portfolio of Securities chosen in the manner described in
the "Summary of Essential Information" in Part A herein. There is, of course, no
guarantee that the Trust's objectives will be achieved.

    The  Trust  consists of  such of  the Securities  listed under  "Schedule of
Portfolio Securities" as may continue to be held from time to time in the  Trust
and  any additional Securities and/or contributed  cash acquired and held by the
Trust pursuant to the  provisions of the  Indenture together with  undistributed
income  therefrom  and  undistributed  cash  realized  from  the  disposition of
Securities (See: "Administration  of the  Trust"). Neither the  Sponsor nor  the
Trustee  shall be liable in any way for any default, failure or defect in any of
the Securities. However,  should any  contract deposited hereunder  fail and  no
substitute  Security be  acquired, the  Sponsor shall  cause to  be refunded the
sales charge relating to such security, plus the pro rata portion of the cost of
the failed contract listed under "Schedule of Portfolio Securities".

    Because certain Securities from time to time may be sold or their percentage
reduced under  certain circumstances  described herein,  and because  additional
Securities  may be deposited into the Trust from  time to time, the Trust is not
expected to retain  for any  length of time  its present  size and  composition.
(See: "Administration of the Trust--Portfolio Supervision".)

    The  Trust is organized as  a unit investment trust  and not as a management
investment company.  Therefore, neither  the  Trustee nor  the Sponsor  has  the
authority  to  manage the  Trust's assets  in  an attempt  to take  advantage of
various market conditions to improve the  Trust's net asset value, and  further,
the  Trust's Securities  may be  disposed of  only under  limited circumstances.
(See: "Administration of the Trust-- Portfolio Supervision".)

    There is no assurance  that any dividends  will be declared  or paid in  the
future  on the Securities initially deposited or to be deposited subsequently in
the Trust.

DISTRIBUTION

    The Record Date and the Distribution Dates  are set forth in Part A  hereto.
(See:  "Summary of Essential Information".) The  distributions will be an amount
equal to such Unit Holder's  pro rata portion of  the amount of dividend  income
received  by  the  Trust  and  proceeds of  the  sale  of  Portfolio Securities,
including capital gains, not used for the redemption of Units, if any (less  the
Trustee's   fees,   Sponsor's   portfolio   supervision   fees   and  expenses).
Distributions for  the  account of  beneficial  owners of  Units  registered  in
"street  name" and held by the Sponsor will be made to the investment account of
such beneficial  owners  maintained  with the  Sponsor.  Whenever  required  for
regulatory  or tax purposes or if otherwise directed by the Sponsor, the Trustee
may make special distributions on special distribution dates to Unit Holders  of
record on special record dates declared by the Trustee.

                            TAX STATUS OF THE TRUST

    In  the opinion of Cahill Gordon & Reindel, special counsel for the Sponsor,
under existing Federal income tax law:

        The Trust is  not an association  taxable as a  corporation for  Federal
    income  tax purposes, and  income received by  the Trust will  be treated as
    income of the Unit Holders in the manner set forth below.

        Each Unit Holder will be considered the  owner of a pro rata portion  of
    each asset in the Trust under the grantor trust rules of Sections 671-678 of
    the  Internal Revenue Code of  1986, as amended (the  "Code"). A Unit Holder
    should determine the  tax cost for  each asset represented  by the  Holder's
    Units  by allocating the total  cost for such Units  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.

        A  Unit Holder will be considered to  have received all of the dividends
    paid on the Holder's pro rata  portion of each Security when such  dividends
    are  received by  the Trust. In  the case  of a corporate  Unit Holder, such
    dividends  will  qualify  for  the  70%  dividends  received  deduction  for
    corporations  to the  same extent as  though the dividend  paying stock were
    held directly by the  corporate Unit Holder. An  individual Unit Holder  who
    itemizes  deductions  will  be entitled  to  an itemized  deduction  for the
    Holder's pro rata share  of fees and  expenses paid by  the Trust as  though
    such  fees and expenses were  paid directly by the  Unit Holder, but only to
    the  extent  that  this  amount  together  with  the  Unit  Holder's   other
    miscellaneous deductions exceeds 2% of the Holder's adjusted gross income. A
    corporate Unit Holder will not be subject to this 2% floor.

        Under  the position  taken by  the Internal  Revenue Service  in Revenue
    Ruling 90-7, a  distribution by  the Trustee  to a  Unit Holder  (or to  the
    Holder's  agent) of such Holder's  PRO RATA share of  the Securities in kind
    upon redemption or termination of the Trust  will not be a taxable event  to
    the Unit Holder. Such Unit Holder's basis for Securities so distributed will
    be equal to the Holder's basis for the same

                                       3
<PAGE>
    Securities  (previously  represented by  the Holder's  Units) prior  to such
    distribution and the holding period for such Securities will be the  shorter
    of the period during which the Unit Holder held the Units and the period for
    which  the Securities  were held  in the  Trust. A  Unit Holder  will have a
    taxable gain or loss,  which will be  a capital gain or  loss except in  the
    case  of a  dealer, when the  Unit Holder  disposes of such  Securities in a
    taxable transfer.

        Under the income tax laws of the  State and City of New York, the  Trust
    is  not an association taxable as a  corporation and the income of the Trust
    will be treated as the income of the Unit Holders.

    If the proceeds  received by the  Trust upon  the sale or  redemption of  an
underlying  Security exceed a  Unit Holder's adjusted tax  cost allocable to the
Security disposed of, that Unit Holder will realize a taxable gain to the extent
of such excess. Conversely, if the proceeds received by the Trust upon the  sale
or  redemption of an underlying Security are  less than a Unit Holder's adjusted
tax cost allocable to the Security disposed of, that Unit Holder will realize  a
loss  for tax  purposes to the  extent of  such difference. Under  the Code, net
capital gain (i.e., the excess of net long-term capital gain over net short-term
capital loss) of individuals, estates and trusts is subject to a maximum nominal
tax rate of 28%. Such net capital gain may, however, result in a disallowance of
itemized deductions and/or affect a personal exemption phase-out.

    Each Unit Holder should consult his, her or its tax advisor with respect  to
the application of the above general information to his, her or its own personal
situation.

                                RETIREMENT PLANS

    Units  of  the Trust  may be  suited for  purchase by  Individual Retirement
Accounts and  pension plans  or profit  sharing and  other qualified  retirement
plans.  Investors  considering  participation  in any  such  plan  should review
specific tax laws and  pending legislation relating  thereto and should  consult
their   attorneys  or  tax  advisors  with  respect  to  the  establishment  and
maintenance of any such plan.

    A qualified retirement  plan provides  employee retirement  benefits and  is
funded  by  contributions  from  the  employer  (including  contributions  by  a
self-employed individual, in  which case the  plan is sometimes  called a  Keogh
plan).  The  contributions are,  within  limits, deductible  in  determining the
taxable income of  the contributing  employer for Federal  income tax  purposes.
Income  received by  the plan  is not taxed  when received  by it  (nor are plan
losses deductible), but distributions  from the plan  are generally included  in
ordinary income of the distributee upon receipt. A lump sum payout of the entire
amount held in such a plan can, however, be eligible for 5 or 10 year averaging.

    An  individual  retirement  account (an  "IRA")  is similar  to  a qualified
retirement plan but contributions to an IRA up to $2,000 per year ($2,250 if  at
least  $250 is contributed  for the benefit of  the worker's non-earning spouse)
are generally  made by  an individual  from  earned income,  rather than  by  an
employer.  An individual is permitted to contribute  to an IRA even though he or
she is  also  covered by  a  qualified retirement  plan;  but, in  the  case  of
higher-income  individuals who are active participants in a qualified retirement
plan, IRA contributions are neither currently deductible nor taxed when paid out
by the IRA (although income earned in  the IRA is taxed as ordinary income  when
distributed). The IRA beneficiary must not have attained age 70 1/2 by the close
of  the taxable year  for which an IRA  contribution is made; and  5 and 10 year
averaging is not allowable for IRA distributions.

    Distributions from qualified retirement plans must begin in minimum  amounts
no  later than  the April 1  following the  calendar year in  which the employee
attains age 70  1/2 or  within 5 years  after his  or her prior  death if  death
occurs  before  distributions  begin  (with  later  distribution  allowed  for a
surviving spouse  and  with lifetime  annuity-type  payouts to  any  beneficiary
permitted).  Minimum required  distributions from  IRAs are  governed by similar
rules.

    Forms and arrangements for establishing qualified retirement plans and  IRAs
are  available from the  Sponsor, as well  as from other  brokerage firms, other
financial institutions and others. Fees and  charges with respect to such  plans
and  IRAs  are not  uniform and  may  vary from  time to  time  as well  as from
institution to institution.

    Distributions received from a  qualified retirement plan  or IRA before  the
employee  attains age  59 1/2 are  subject to  a 10% additional  tax, unless the
distribution is (i) made on or after the employee's death, (ii) attributable  to
his  disablement,  (iii) in  the  nature of  a life  annuity,  (iv) made  to the
employee after separation from service after  attainment of age 55, or (v)  made
for  other  reasons  specified  in  the  law.  Qualifying  distributions  from a
qualified retirement  plan  or from  an  IRA may,  however,  be rolled  over  or
transferred  to  another  qualified  retirement  plan  or  IRA  under  specified
circumstances.

    The foregoing information  is of a  general nature, does  not purport to  be
complete  and  relates  only  to  the Federal  income  tax  rules  applicable to
qualified retirement plans and IRAs. State  and local tax rules and foreign  tax
regimes  may  treat  qualified  retirement plans  and  IRAs  differently. Anyone
contemplating establishing a qualified retirement plan or IRA or investing funds
of such a plan or IRA in Trust units should consult his, her or its tax  advisor
with  respect to the tax consequences of  any such action and the application of
the foregoing general tax information to his, her or its particular situation.

                            PUBLIC OFFERING OF UNITS

PUBLIC OFFERING PRICE

   
    The Public Offering Price of the  Units is calculated daily and is  computed
by  adding  to  the  aggregate  market value  of  the  Portfolio  Securities (as
determined by the  Trustee) next  computed after  receipt of  a purchase  order,
divided  by the number of Units outstanding,  the sales charge shown in "Summary
of Essential Information" and applicable commissions. After the initial Date  of
Deposit,  a proportionate share  of amounts in the  Income Account and Principal
Account and amounts receivable in  respect of stocks trading ex-dividend  (other
than money required to be distributed to Unit Holders on a Distribution Date and
money  required to redeem tendered Units) is added to the Public Offering Price.
In the event a stock is trading ex-dividend at the time of deposit of additional
Securities, an amount equal to the dividend that would be received if such stock
were to receive a dividend will be added to the Public Offering Price. The sales
charge will  decline over  the life  of the  Trust in  the manner  described  in
"Summary  of Essential Information--Public Offering  Price". The Public Offering
Price per Unit is calculated  to five decimal places and  rounded up or down  to
three decimal places. The Public Offering Price on any particular date will vary
from the Public Offering Price on the Date of Deposit (set forth in the "Summary
of  Essential  Information") in  accordance with  fluctuations in  the aggregate
market value of  the Securities, the  amount of  available cash on  hand in  the
Trust and the amount of certain accrued fees and expenses.
    

    As  more fully described in the Indenture, the aggregate market value of the
Securities is determined on  each business day by  the Trustee based on  closing
prices  on the  day the  valuation is  made or,  if there  are no  such reported
prices,  by   taking  into   account  the   same  factors   referred  to   under
"Redemption--Computation  of Redemption Price". Determinations are effective for
transactions effected subsequent to the last preceding determination.

PUBLIC DISTRIBUTION

    Units issued on the Date of  Deposit and Additional Units issued in  respect
of  additional deposits of Securities  will be distributed to  the public by the
Sponsor and through dealers at the Public Offering Price determined as  provided
above.  Unsold Units or  Units acquired by  the Sponsor in  the secondary market
referred to below may be  offered to the public by  this Prospectus at the  then
current Public Offering Price determined as provided above.

    The  Sponsor intends to qualify Units in  states selected by the Sponsor for
sale by  the  Sponsor  and through  dealers  who  are members  of  the  National
Association  of Securities  Dealers, Inc.  Sales to  dealers during  the initial
offering period will be made at prices which reflect a concession of 70% of  the
applicable sales charge, subject to change from time to time. In addition, sales
of  Units may be  made pursuant to distribution  arrangements with certain banks
and/or other entities subject to regulation by the Office of the Comptroller  of
the  Currency (including NationsSecurities, a  partnership created pursuant to a
joint venture between NationsBank  of North Carolina, N.A.  and an affiliate  of
the  Sponsor) which are acting as agents for their customers. These banks and/or
entities are making Units of the Trust available to their customers on an agency
basis. A portion of the sales charge  paid by these customers is retained by  or
remitted  to such banks  or entities in  an amount equal  to the fee customarily
received by an agent for acting in such capacity in connection with the purchase
of Units.  The  Glass-Steagall Act  prohibits  banks from  underwriting  certain
securities,  including Units of the Trust; however, this Act does permit certain
agency transactions,  and  banking  regulators have  not  indicated  that  these
particular  agency transactions are  impermissible under this  Act. In Texas, as
well as certain other states, any bank making Units available must be registered
as a broker-dealer in that State. The  Sponsor reserves the right to reject,  in
whole or in part, any order for the purchase of Units.

SECONDARY MARKET

    While  not obligated  to do  so, it  is the  Sponsor's present  intention to
maintain, at its expense,  a secondary market  for Units of  this series of  the
Dean  Witter Select Equity  Trust and to continuously  offer to repurchase Units
from Unit Holders at  the Sponsor's Repurchase  Price. The Sponsor's  Repurchase
Price  is computed  by adding to  the aggregate  value of the  Securities in the
Trust, any cash on  hand in the Trust  including dividends receivable on  stocks
trading ex-dividend (other than money required to redeem tendered Units and cash
deposited  by the  Sponsor to  purchase Securities or  cash held  in the Reserve
Account) and deducting therefrom expenses  of the Trustee, Sponsor, counsel  and
taxes,  if any, and cash held for distribution to Unit Holders of record as of a
date on or prior to the evaluation;  and then dividing the resulting sum by  the
number  of Units outstanding,  as of the  date of such  computation. There is no
sales charge incurred when a  Unit Holder sells Units  back to the Sponsor.  Any
Units  repurchased  by the  Sponsor  at the  Sponsor's  Repurchase Price  may be
reoffered to  the public  by the  Sponsor at  the then  current Public  Offering
Price. Any profit or loss resulting from the resale of such Units will belong to
the Sponsor.

    If  the supply of Units  exceeds demand (or for  any other business reason),
the Sponsor may, at any time,  occasionally, from time to time, or  permanently,
discontinue  the repurchase of Units of  this series at the Sponsor's Repurchase
Price. In such event, although under no obligation to do so, the Sponsor may, as
a service to Unit Holders, offer to repurchase Units at the "Redemption  Price".
Alternatively, Unit Holders may redeem their Units through the Trustee.

PROFIT OF SPONSOR

    The  Sponsor receives  a sales  charge on  Units sold  to the  public and to
dealers. The Sponsor may have  also realized a profit  (or sustained a loss)  on
the  deposit of the Securities in  the Trust representing the difference between
the   cost   of   the   Securities   to   the   Sponsor   and   the   cost    of

                                       5
<PAGE>
the  Securities to the Trust (for a description of such profit (or loss) and the
amount of  such difference  on the  initial Date  of Deposit  see: "Schedule  of
Portfolio  Securities"). The Sponsor  may realize a similar  profit (or loss) in
connection with each additional deposit of Securities. In addition, the  Sponsor
may  have acted as broker in transactions relating to the purchase of Securities
for deposit in the Trust. During the initial public offering period the  Sponsor
may  realize additional profit (or sustain a  loss) due to daily fluctuations in
the prices of the Securities in the Trust and thus in the Public Offering  Price
of Units received by the Sponsor. Cash, if any, received by the Sponsor from the
Unit  Holders prior to the settlement date for purchase of Units or prior to the
payment for Securities upon their delivery may be used in the Sponsor's business
and may be of benefit to the Sponsor.

    The Sponsor may also realize profits (or sustain losses) while maintaining a
secondary market  in the  Units, in  the amount  of any  difference between  the
prices  at which  the Sponsor  buys Units  and the  prices at  which the Sponsor
resells such Units (such prices include a  sales charge) or the prices at  which
the Sponsor redeems such Units, as the case may be.

VOLUME DISCOUNT

    Although  under no obligation to do so, the Sponsor intends to permit volume
purchasers of Units  to purchase  Units at a  reduced sales  charge during  such
period  as the highest sales charge is 3.90%. The Sponsor may at any time change
the amount by which the sales charge is reduced, or may discontinue the discount
altogether.

    The sales  charge of  3.90% of  the Public  Offering Price  will be  reduced
pursuant  to the following graduated  scale for sales to  any person of at least
$25,000.

    The reduced sales  charges as shown  on the  chart above will  apply to  all
purchases  of Units of this Trust on any one day by the same person, partnership
or corporation (other than a dealer), in the amounts stated herein.

    Units held  in the  name of  the  purchaser's spouse  or in  the name  of  a
purchaser's  child under  the age 21  are deemed  for the purposes  hereof to be
registered in the  name of  the purchaser. The  reduced sales  charges are  also
applicable  to  a  trustee  or  other  fiduciary,  including  a  partnership  or
corporation purchasing  Units for  a  single trust  estate or  single  fiduciary
account.

    The dealer concession will be 70% of the sales charge per Unit.

                                   REDEMPTION

RIGHT OF REDEMPTION

    One  or  more Units  represented by  a  Certificate may  be redeemed  at the
Redemption Price upon  tender of  such Certificate to  the Trustee  at its  unit
investment  trust  office  in  the  City  of  New  York,  properly  endorsed  or
accompanied by a  written instrument  of transfer  in form  satisfactory to  the
Trustee  (as set forth in  the Certificate), and executed  by the Unit Holder or
its authorized attorney. A  Unit Holder may tender  its Units for redemption  at
any  time after the settlement date for purchase, whether or not it has received
a definitive Certificate.  The Redemption Price  per Unit is  calculated as  set
forth under "Computation of Redemption Price". There is no sales charge incurred
when a Unit Holder tenders its Units to the Trustee for redemption.

    On  the  seventh  calendar  day  following  the  tender  to  the  Trustee of
Certificates representing Units to be redeemed  (or if the seventh calendar  day
is  not a Business  Day, on the first  Business Day day  prior thereto) the Unit
Holder will be entitled to receive monies per Unit equal to the Redemption Price
per Unit as determined by the Trustee as  of the Evaluation Time on the date  of
tender.

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

    Units will be redeemed by the Trustee solely in cash for any one Unit Holder
tendering less than 2,500 Units.  With respect to redemption requests  regarding
at  least 2,500 Units, the  Sponsor may determine, in  its discretion, to direct
the Trustee to redeem  Units "in kind" by  distributing Portfolio Securities  to
the  redeeming Unit Holder. The  Sponsor may direct the  Trustee to redeem Units
"in kind" even  if it is  then maintaining a  secondary market in  Units of  the
Trust.  Unit Holders  redeeming "in  kind" will receive  an amount  and value of
Trust Securities per

                                       6
<PAGE>
Unit equal to the Redemption Price Per  Unit as determined as of the  Evaluation
Time  next  following  the tender  as  set  forth herein  under  "Computation of
Redemption Price" below. The distribution "in kind" for redemption of Units will
be held by the  Trustee for the  account of, and  for disposition in  accordance
with  the instructions of, the tendering  Unit Holder. The tendering Unit Holder
will be entitled  to receive whole  shares of each  of the underlying  Portfolio
Securities,  plus cash  equal to the  Unit Holder's  pro rata share  of the cash
balance of the Income and Principal Accounts and cash from the Principal Account
equal to the fractional shares to which such tendering Unit Holder is  entitled.
The Trustee, in connection with implementing the redemption "in kind" procedures
outlined  above,  may  make  any adjustments  necessary  to  reflect differences
between  the  Redemption  Price  of  Units  and  the  value  of  the  Securities
distributed  "in kind" as of  the date of tender.  If the Principal Account does
not contain amounts sufficient  to cover the required  cash distribution to  the
tendering  Unit Holder, the Trustee is empowered to sell Securities in the Trust
Portfolio in  the manner  discussed below.  A Unit  Holder receiving  redemption
distributions  of Securities  "in kind"  may incur  brokerage costs  and odd-lot
charges in converting Securities so received into cash. The Trustee will  assess
transfer  charges to Unit  Holders taking Securities "in  kind" according to its
usual practice.

    The portion  of the  Redemption  Price which  represents the  Unit  Holder's
interest in the Income Account shall be withdrawn from the Income Account to the
extent  available.  The  balance  paid on  any  redemption,  including dividends
receivable on  stocks trading  ex-dividend,  if any,  shall  be drawn  from  the
Principal  Account to the extent that funds  are available for such purpose. The
Trustee is authorized by  the Agreement to sell  Securities in order to  provide
funds  for redemption. To the extent Securities are sold, the size and diversity
of the  Trust will  be reduced.  Such sales  may be  required at  the time  when
Securities  would not otherwise  be sold and  might result in  lower prices than
might otherwise be realized. The Redemption  Price received by a tendering  Unit
Holder  may be more or less than the purchase price originally paid by such Unit
Holder, depending on the value of the Securities in the Portfolio at the time of
redemption. Moreover, due  to the minimum  lot size in  which Securities may  be
required  to be sold, the proceeds of such sales may exceed the amount necessary
for payment of Units redeemed. Such excess proceeds will be distributed pro rata
to all remaining Unit Holders of record on the Distribution Date.

    Securities to be sold for purposes of redeeming Units will be selected  from
a list supplied by the Sponsor. If not so instructed by the Sponsor, the Trustee
will  select  the  Securities  to be  sold  so  as to  maintain,  as  closely as
practicable, the proportionate relationship between the number of shares of each
Security in the Trust.

COMPUTATION OF REDEMPTION PRICE

    The Trust Evaluation per Unit is determined as of the Evaluation Time stated
under "Summary of Essential Information" above and (a) semiannually, on the last
Business Day of each of the months of June and December, (b) on the day on which
any Unit of the Trust  is tendered for redemption  (unless tender is made  after
the  Evaluation Time on such  day, in which case Tender  shall be deemed to have
been made  on the  next  day subsequent  thereto on  which  the New  York  Stock
Exchange  is open for trading) and (c) on  any other Business Day desired by the
Sponsor or the Trustee, (1) by adding:

        a.  The aggregate value of Securities in the Trust, as determined by the
    Trustee;

        b.  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;

        c.  All other assets of the Trust.

    (2) and then, by deducting  from the resulting figure: amounts  representing
any  applicable  taxes or  governmental  charges payable  by  the Trust  for the
purpose of  making  an  addition to  the  reserve  account (as  defined  in  the
Agreement,  the "Reserve Account"), amounts  representing estimated accrued fees
and expenses  of the  Trust  (including legal  and auditing  expenses),  amounts
representing unpaid fees of the Trustee, the Sponsor and counsel and monies held
to  redeem tendered Units and  for distribution to Unit  Holders of record as of
the Business Day prior  to the Evaluation  being made on the  days or dates  set
forth above and then;

    (3)  by dividing the result of the  above computation by the total number of
Units outstanding on the  date of such Evaluation.  The resulting figure  equals
the Redemption Price for each Unit.

    The  aggregate value of the Securities shall be determined by the Trustee in
good faith in the following manner: If the Securities are listed on one or  more
national  securities exchanges,  such valuation  shall be  based on  the closing
price on such Exchange which  is the principal market  thereof deemed to be  the
New York Stock Exchange if the Securities are listed thereon (unless the Trustee
deems  such price inappropriate as a basis for valuation). If the Securities are
not so listed, or, if so listed and the principal market therefor is other  than
such  exchange or  there is  no closing price  on such  exchange, such valuation
shall be based on the closing  price in the over-the-counter market (unless  the
Trustee  deems such price inappropriate as a basis for valuation) or if there is
no such closing price, by any of  the following methods which the Trustee  deems
appropriate:  (i)  on the  basis of  current  bid prices  of such  Securities as
obtained from  investment  dealers  or brokers  (including  the  Depositor)  who
customarily deal in securities comparable to those held by the Trust, or (ii) if
bid  prices are not  available for any of  such Securities, on  the basis of bid
prices for comparable  securities, or  (iii) by appraisal  of the  value of  the
Securities on the bid side of the market or by such other appraisal as is deemed
appropriate, or (iv) by any combination of the above.

POSTPONEMENT OF REDEMPTION

    The right of redemption may be suspended and payment of the Redemption Price
per Unit postponed for more than seven calendar days following a tender of Units
for redemption (i) for any period during which the New York Stock Exchange, Inc.
is  closed, other than for  customary weekend and holiday  closings, or (ii) for
any  period  during  which,  as  determined  by  the  Securities  and   Exchange
Commission, either trading on the New York Stock Exchange, Inc. is restricted or
an  emergency  exists  as  a  result of  which  disposal  or  evaluation  of the
Securities is not reasonably practicable, or (iii) for such other periods as the
Securities and  Exchange Commission  may by  order permit.  The Trustee  is  not
liable  to any person or in any way for  any loss or damage that may result from
any such suspension or postponement.

                                EXCHANGE OPTION

    Unit Holders of any Dean Witter Select Trust or any holders of units of  any
other  unit investment trust (collectively, "Holders") may elect to exchange any
or all of their units for units of one or more of any series of the Dean  Witter
Select  Equity Trust or for  units of any other  Dean Witter Select Trusts, that
may from time to time  be made available for such  exchange by the Sponsor  (the
"Exchange  Trusts"). Such units may be acquired at prices based on reduced sales
charges per unit.  The purpose of  such reduced  sales charge is  to permit  the
Sponsor  to pass on to the Holder who  wishes to exchange units the cost savings
resulting from such exchange.  The cost savings result  from reductions in  time
and  expense  related  to  advice, financial  planning  and  operational expense
required for the Exchange  Option. The following  Exchange Trusts are  currently
available:  the  Dean  Witter Select  Municipal  Trust, the  Dean  Witter Select
Government Trust, the Dean  Witter Select Equity Trust,  the Dean Witter  Select
Investment Trust and the Dean Witter Select Corporate Trust.

    Each  Exchange Trust  has different  investment objectives:  a Holder should
read the Prospectus for the applicable Exchange Trust carefully to determine the
investment objective prior to exercise of this option.

    This option will  be available  provided the Sponsor  maintains a  secondary
market  in units of the applicable Exchange Trust and provided that units of the
applicable Exchange Trust are available for sale and are lawfully qualified  for
sale  in the state in which the Holder  is a resident. While it is the Sponsor's
present intention  to maintain  a secondary  market for  the units  of  Exchange
Trusts,  there is  no obligation on  its part to  do so. Therefore,  there is no
assurance that a market for units will in fact exist on any given date in  which
a  Holder wishes to sell or exchange Units; thus, there is no assurance that the
Exchange Option will be available to  any Unit Holder. The Sponsor reserves  the
right  to modify, suspend or  terminate this option at  any time without further
notice to Unit Holders. In the event  the Exchange Option is not available to  a
Unit  Holder at the  time such Unit  Holder wishes to  exercise such option, the
Unit Holder  will be  immediately notified  and  no action  will be  taken  with
respect to such tendered Units without further instruction from the Unit Holder.

    Exchanges will be affected in whole units only. Any excess proceeds from the
surrender of a Unit Holder's Units will be returned. Alternatively, Unit Holders
will  be permitted to make up any difference between the amount representing the
Units being submitted for exchange and  the amount representing the units  being
acquired  up to the next highest number of  whole units. Unit Holders in a trust
which utilizes the Select 10 Strategy will be permitted to add an amount not  to
exceed  the amount of the first semiannual distribution distributed to such Unit
Holders in connection with an exchange of their Units for Units of another trust
which utilizes the Select 10 Strategy.

    An exchange  of  Units  pursuant  to  the  Exchange  Option  will  generally
constitute  a "taxable event"  under the Code,  i.e., a Holder  will recognize a
gain or loss at the time of exchange. However, an exchange of Units for Units of
any series of  the Exchange  Trusts which are  grantor trusts  for U.S.  federal
income  tax purposes will not constitute a  taxable event to the extent that the
underlying securities in each Trust do  not differ materially either in kind  or
in  extent. A Unit Holder who exchanges Units  of one Trust for Units of another
Trust should consult his or her tax  advisor regarding the extent to which  such
exchange  results in the recognition of a  gain or loss for Federal and/or state
or local income tax purposes.

    To exercise the Exchange Option, a Unit Holder should notify the Sponsor  of
the  desire to acquire units of one or  more of the Exchange Trusts. If units of
the applicable  outstanding  series of  the  Exchange  Trust are  at  that  time
available for sale, the Unit Holder may select the series or group of series for
which  the Units are  to be exchanged. The  Unit Holder will  be provided with a
current prospectus or prospectuses relating to each series in which interest  is
indicated.

    The  exchange transaction will operate in  a manner essentially identical to
any secondary market  transaction, i.e., Units  will be repurchased  at a  price
based  upon the aggregate bid side evaluation  per Unit of the Securities in the
Portfolio. Units of  the Exchange Trust  will be sold  to the Unit  Holder at  a
price  equal to the net asset value based on the offering or bid side evaluation
(as applicable) per unit  of the securities in  the Exchange Trust's  Portfolio,
plus  accrued interest, if any,  and the applicable sales  charge of 2.0% of the
Public Offering Price per Unit.

                              REINVESTMENT PROGRAM

    Unit Holders may elect to have the distributions with respect to their Units
automatically reinvested  in  additional Units  of  the Trust  without  a  sales
charge. The Unit Holder may participate in the Trust's reinvestment program (the
"Program")  by filing with  the Trustee a  written notice of  election. The Unit
Holder's completed notice  of election  to participate  in the  Program must  be
received by the Trustee at least ten days prior to the Record Date applicable to
any  distribution  in  order  for  the  Program  to  be  in  effect  as  to such
distribution. Elections may be modified or revoked on similar notice.

   
    Such distributions, to the extent reinvested  in the Trust, will be used  by
the  Trustee at  the direction of  the Sponsor in  one or both  of the following
manners. (i) The distributions may be used  by the Trustee to purchase Units  of
this  Series of the  Trust held in  the Sponsor's inventory.  The purchase price
payable by the Trustee for  each of such Units will  be equal to the  applicable
Trust  evaluation  per Unit  on  (or as  soon as  possible  after) the  close of
business on the Distribution Date. The Units so purchased by the Trustee will be
issued or credited to the accounts of Unit Holders participating in the Program.
(ii) If there are no Units in the Sponsor's inventory, the Sponsor may  purchase
additional  Securities  for deposit  into the  Trust and/or  deposit cash  (or a
letter of credit in lieu of cash)  with instructions to the Trustee to  purchase
additional  Securities (as described in  "Prospectus Part B--Introduction.") The
additional Securities with any necessary cash  will be deposited by the  Sponsor
with  the Trustee in exchange for new  Units. The distributions may then be used
by the Trustee to purchase  the new Units from the  Sponsor. The price for  such
new  Units will be  the applicable Trust evaluation  per Unit on  (or as soon as
possible after) the  close of business  on the Distribution  Date. (See  "Public
Offering  of  Units--Public  Offering Price.")  The  Units so  purchased  by the
Trustee will be issued or credited to the accounts of Unit Holders participating
in the  Program. The  Sponsor may  terminate the  Program if  it does  not  have
sufficient  Units in its inventory or it is no longer deemed practical to create
additional Units.
    

    No fractional Units will  be issued under any  circumstances. If, after  the
maximum  number of  full Units  has been  issued or  credited at  the applicable
price, there remains a  portion of the distribution  which is not sufficient  to
purchase  a full Unit  at such price,  the Trustee will  distribute such cash to
Unit Holders. The cost of administering  the reinvestment program will be  borne
by the Trust and thus will be borne indirectly by all Unit Holders.

                             RIGHTS OF UNIT HOLDERS

UNIT HOLDERS

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

    Ownership of Units  is evidenced  by registered  Certificates of  Beneficial
Interest  issued  in denominations  of one  or  more Units  and executed  by the
Trustee and the Sponsor. These Certificates are transferable or  interchangeable
upon  presentation at the unit investment  trust office of the Trustee, properly
endorsed or accompanied by an instrument of transfer satisfactory to the Trustee
and executed by the  Unit Holder or its  authorized attorney, together with  the
payment  of $2.00, if  required by the Trustee,  or such other  amount as may be
determined by the  Trustee and approved  by the  Sponsor, and any  other tax  or
governmental  charge imposed upon the transfer of Certificates. The Trustee will
replace any  mutilated,  lost,  stolen  or  destroyed  Certificate  upon  proper
identification,  satisfactory  indemnity and  payment  of charges  incurred. Any
mutilated Certificate must  be presented  to the Trustee  before any  substitute
Certificate will be issued.

    Under  the terms and  conditions and at  such times as  are permitted by the
Trustee, Units may also be held in uncertificated form. The rights of any holder
of Units held in  uncertificated form shall  be the same as  those of any  other
Unit Holder.

CERTAIN LIMITATIONS

    The death or incapacity of any Unit Holder will not operate to terminate the
Trust  nor entitle  the legal  representatives or heirs  of such  Unit Holder to
claim an accounting or to take any other action or proceeding in any court for a
partition or winding up of the Trust.

    No Unit Holder shall have the right  to vote except with respect to  removal
of  the Trustee or amendment and termination of the Trust. (See: "Administration
of the Trust--Amendment" and  "Administration of the Trust--Termination".)  Unit
Holders  shall have no right  to control the operation  or administration of the
Trust in any manner, except upon the vote of 51% of the Unit Holders outstanding
at any time for purposes of amendment, or termination of the Trust or  discharge
of  the Trustee, all as provided in the Agreement; however, no Unit Holder shall
ever be under  any liability  to any  third party for  any action  taken by  the
Trustee  or  Sponsor. Unit  Holders  will be  unable to  dispose  of any  of the
Securities in  the  Portfolio,  as such,  and  will  not be  able  to  vote  the
Securities.  The Trustee, as  holder of the  Securities, will have  the right to
vote all  of  the voting  Securities  held in  the  Trust, and  will  vote  such
Securities  in  accordance  with  the instructions  of  the  Sponsor,  if given,
otherwise the Trustee shall vote as it, in its sole discretion, shall determine.

                              EXPENSES AND CHARGES

INITIAL EXPENSES

    All expenses and charges  incurred prior to or  in the establishment of  the
Trust  including the cost of the  initial preparation, printing and execution of
the Indenture and  Agreement and  the Certificates, initial  legal and  auditing
expenses,   brokerage  charges  and  commissions   incurred  in  purchasing  the
Securities, the cost of the preparation and printing of this Prospectus and  all
other advertising and selling expenses, have, or will be paid by the Sponsor and
not by the Trust.

FEES

    The  Sponsor's fee, earned for portfolio supervisory services, is based upon
the largest  number  of  Units outstanding  during  the  semiannual  computation
period.  The Sponsor's fee is as set forth in "Summary of Essential Information"
may exceed the actual costs of providing portfolio supervisory services for this
Trust, but at no time will the  total amount the Sponsor receives for  portfolio
supervisory  services rendered  to all series  of the Dean  Witter Select Equity
Trust in any calendar  year exceed the  aggregate cost to  it of supplying  such
services in such year.

    Under the Indenture and Agreement for its services as Trustee and evaluator,
the  Trustee receives the  fee set forth in  "Summary of Essential Information".
Certain regular expenses of  the Trust, including  certain mailing and  printing
expenses, are borne by the Trust.

    The  Sponsor's fee and the Trustee's fees  accrue daily but are payable only
on or before each Distribution Date from the Income Account, to the extent funds
are available and thereafter from the Principal Account. Any of such fees may be
increased without approval of the Unit Holders in proportion to increases  under
the  classification  "All  Services  Less  Rent"  in  the  Consumer  Price Index
published by the United States Department of Labor or, if no longer published, a
similar index. The Trustee, pursuant to normal banking procedures, also receives
benefits to the extent  that it holds funds  on deposit in various  non-interest
bearing accounts created under the Indenture and Agreement.

OTHER CHARGES

    The following additional charges are or may be incurred by the Trust as more
fully  described in  the Indenture  and Agreement: (a)  fees of  the Trustee for
extraordinary services,  (b)  expenses  of  the  Trustee  (including  legal  and
auditing  expenses)  and  of  counsel designated  by  the  Sponsor,  (c) various
governmental charges, (d) expenses and costs of any action taken by the  Trustee
to  protect the  Trust and  the rights  and interests  of the  Unit Holders, (e)
indemnification of the Trustee for any  loss, liability or expenses incurred  by
it  in  the administration  of the  Trust without  gross negligence,  bad faith,
wilful malfeasance or wilful misconduct on its part or reckless disregard of its
obligations and  duties, (f)  indemnification  of the  Sponsor for  any  losses,
liabilities  and expenses incurred  in acting as Sponsor  or Depositor under the
Agreement without  gross negligence,  bad faith,  wilful malfeasance  or  wilful
misconduct or reckless disregard of its obligations and duties, (g) expenditures
incurred  in  contacting Unit  Holders upon  termination of  the Trust,  and (h)
brokerage commissions or  charges incurred  in connection with  the purchase  or
sale of Securities.

    The fees and expenses set forth herein are payable out of the Trust and when
so paid by or owing to the Trustee are secured by a lien on the Trust. Dividends
on the Securities are expected to be sufficient to pay the estimated expenses of
the  Trust. If the balances in the Income and Principal Account are insufficient
to provide for amounts payable by the  Trust, the Trustee has the power to  sell
Securities  to pay such amounts. To the  extent Securities are sold, the size of
the Trust will be  reduced and the  proportions of the  types of Securities  may
change.  Such  sales might  be  required at  a  time when  Securities  would not
otherwise be  sold and  might result  in lower  prices than  might otherwise  be
realized.  Moreover, due  to the  minimum lot  size in  which Securities  may be
required to be sold, the proceeds of such sales may exceed the amount  necessary
for the payment of such fees and expenses.

                          ADMINISTRATION OF THE TRUST

RECORDS AND ACCOUNTS

    The  Trustee will keep records and accounts of all transactions of the Trust
at its unit investment trust  office at 101 Barclay  Street, New York, New  York
10286.  These  records and  accounts will  be available  for inspection  by Unit
Holders at  reasonable times  during  normal business  hours. The  Trustee  will
additionally keep on file for inspection by Unit Holders an executed copy of the
Indenture and Agreement together with a current list of the Securities then held
in  the Trust. In connection with the storage and handling of certain Securities
deposited in  the  Trust, the  Trustee  is authorized  to  use the  services  of
Depository  Trust  Company.  These  services would  include  safekeeping  of the
Securities, coupon-clipping,  computer  book-entry  transfer  and  institutional
delivery  services.  The Depository  Trust Company  is  a limited  purpose trust
company organized under the Banking  Law of the State of  New York, a member  of
the Federal Reserve System and a clearing agency registered under the Securities
Exchange Act of 1934.

DISTRIBUTION

    Dividends  payable to the Trust as a  holder of record of its Securities are
credited by the Trustee to an Income Account, as of the date on which the  Trust
is  entitled  to receive  such dividends.  Other  receipts, including  return of
investment and  gain  and  amounts  received upon  the  sale,  pursuant  to  the
Indenture  and Agreement, of rights to  purchase other Securities distributed in
respect of the Securities in the Portfolio, are credited to a Principal Account.
Any distribution for each Unit Holder as of the Record Date will be made on  the
Distribution  Date  or  shortly  thereafter  and  shall  consist  of  an  amount
approximately equal to the dividend  income per Unit, after deducting  estimated
expenses,  if any, plus such  Holder's pro rata share  of the distributable cash
balance of the Principal Account. Proceeds received from the disposition of  any
of the Securities which are not used for redemption of Units will be held in the
Principal  Account to be distributed on  the Distribution Date following receipt
of such proceeds. No distribution need be made from the Principal Account if the
balance therein is less than $1.00 per 100 Units outstanding. A Reserve  Account
may  be  created by  the Trustee  by  withdrawing from  the Income  or Principal
Accounts, from time to time, such amounts  as it deems requisite to establish  a
reserve  for any taxes or other governmental  charges that may be payable out of
the Trust. Funds held by the Trustee  in the various accounts created under  the
Indenture are non-interest bearing to Unit Holders.

   
    The  Trustee will follow a policy  that it will place securities acquisition
or disposition transactions with a broker or dealer only if it expects to obtain
the most favorable prices and  executions of orders. Transactions in  securities
held in the Trust are generally made in brokerage transactions (as distinguished
from  principal transactions) and the  Sponsor may act as  broker therein if the
Trustee expects thereby to obtain the  most favorable prices and execution.  The
furnishing  of statistical and research information to the Trustee by any of the
securities  dealers  through  which  transactions  are  executed  will  not   be
considered in placing securities transactions.
    

PORTFOLIO SUPERVISION

   
    The original proportionate relationship between the number of shares of each
Security  in the  Trust will be  adjusted to  reflect the occurrence  of a stock
dividend, a stock split, merger, reorganization or a similar event which affects
the capital structure of the  issuer of a Security in  the Trust but which  does
not  affect the Trust's percentage ownership of  the common stock equity of such
issuer at  the time  of such  event. If  the Trust  receives the  securities  of
another  issuer as the result  of a merger or  reorganization of, or a spin-off,
split-off or  split-up by  the issuer  of a  Security included  in the  original
portfolio,  the  Trust may  hold those  securities as  if they  were one  of the
Securities  initially  deposited  and  adjust  the  proportionate   relationship
accordingly  for all future  subsequent deposits. The Portfolio  of the Trust is
not "managed" by the  Sponsor or the Trustee;  their activities described  below
are  governed  solely by  the  provisions of  the  Indenture and  Agreement. The
Sponsor may direct  the Trustee  to dispose of  Securities upon  failure of  the
issuer  of a Security in the Trust to declare or pay anticipated cash dividends,
institution of  certain  materially  adverse legal  proceedings,  default  under
certain  documents  materially  and adversely  affecting  future  declaration or
payment of dividends, or the occurrence  of other market or credit factors  that
in the opinion of the Sponsor would make the retention of such Securities in the
Trust  detrimental to  the interests  of the  Unit Holders.  Except as otherwise
discussed herein, the  acquisition of any  Securities for the  Trust other  than
those  initially deposited and deposited in order to create additional Units, is
prohibited. The Sponsor is authorized under the Indenture to direct the  Trustee
to invest the proceeds of any sale of Securities not required for the redemption
of Units in eligible money market instruments selected by the Sponsor which will
include  only negotiable  certificates of deposit  or time  deposits of domestic
banks which are members of the  Federal Deposit Insurance Corporation and  which
have,  together with  their branches  or subsidiaries,  more than  $2 billion in
total assets, except that  certificates of deposit or  time deposits of  smaller
domestic  banks may be held  provided the deposit does  not exceed the insurance
coverage on the instrument (which  currently is $100,000), and provided  further
that  the Trust's aggregate holding of  certificates of deposit or time deposits
issued by the Trustee may not exceed the insurance coverage of such  obligations
and  U.S.  Treasury  notes or  bills  each of  which  mature prior  to  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 such other reviews and procedures as it may deem necessary in order  for
it to give the consents and directions, including directions as to voting on the
underlying  Securities,  required  by  the  Indenture  and  Agreement.  For  the
administrative services performed in making such recommendations and giving such
consents and directions,  and in  making the  reviews called  for in  connection
therewith  the Sponsor shall  receive the portfolio  supervisory fee referred to
under "Summary of Essential Information".

VOTING OF THE PORTFOLIO SECURITIES

    Pursuant to the Indenture and Agreement,  voting rights with respect to  the
Portfolio  Securities and Replacement  Securities, if any,  will be exercised by
the Trustee in  accordance with  the Indenture or  the directions  given by  the
Sponsor.

                                       11
<PAGE>
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, expressed  in each case as  a dollar amount  per
Unit.

    Within  a reasonable  period of  time after  the last  Business Day  in each
calendar year, but not later than February 15, the Trustee will furnish to  each
person  who at any time during such calendar  year was a Unit Holder of record a
statement setting forth:

        1.  As to the Income and Principal Account:

           (a) the amount of income received on the Securities;

           (b) the amount paid for redemption of Units;

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

           (d) the amounts distributed from the Income Account;

           (e) any other amount  credited or deducted  from the Income  Account;
       and

           (f)   the  net amount  remaining after  such payments  and deductions
       expressed both as a total dollar amount  and as a dollar amount per  Unit
       outstanding on the last business day of such calendar year.

        2.  The following information:

           (a)  a list  of the Securities  as of  the last business  day of such
       calendar year;

           (b) the number of  Units outstanding as of  the last business day  of
       such calendar year;

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

           (d) the amounts actually distributed  during such calendar year  from
       the  Income and Principal Accounts,  separately stated, expressed both as
       total dollar amounts and  as dollar amounts per  Unit outstanding on  the
       Record Dates for such distributions.

AMENDMENT

    The  Indenture and Agreement may be amended from time to time by the Trustee
and the Sponsor or  their respective successors, without  the consent of any  of
the  Unit Holders  (a) to  cure any  ambiguity or  to correct  or supplement any
provision contained  therein which  may be  defective or  inconsistent with  any
other provision contained therein; (b) to change any provision thereof as may be
required by the Securities and Exchange Commission or any successor governmental
agency  exercising similar  authority; or  (c) to  make such  other provision in
regard to matters or questions arising thereunder as shall not adversely  affect
the interest of the Unit Holders; provided, that the Indenture and Agreement may
also  be amended from time to time by the parties thereto (or the performance of
any of the provisions of  this Indenture and Agreement  may be waived) with  the
expressed  written consent of  Unit Holders evidencing  51% of the  Units at the
time outstanding under the Indenture and Agreement for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions  of
the Indenture and Agreement or of modifying in any manner the rights of the Unit
Holders;  provided, further however, that the Indenture and Agreement may not be
amended (nor may  any provision thereof  be waived)  so as to  (1) increase  the
number  of Units  issuable in  respect of the  Trust above  the aggregate number
specified in  Part  II  of  the  Agreement or  such  lesser  amount  as  may  be
outstanding at any time during the term of the Indenture except as the result of
the  deposit  of  Additional  Securities, as  therein  provided,  or  reduce the
relative interest  in the  Trust of  any Unit  Holder without  his consent,  (2)
permit  the deposit  or acquisition thereunder  of securities  or other property
either in addition to or in substitution for any of the Securities except in the
manner permitted by the Trust  Indenture as in effect on  the date of the  first
deposit  of Securities or permit the Trustee to engage in business or investment
activities not  specifically  authorized  in  the  Indenture  and  Agreement  as
originally  adopted or (3) adversely affect the characterization of the Trust as
a grantor trust for federal income tax purposes.

TERMINATION

    The Indenture  and Agreement  provides  that the  Trust will  be  liquidated
during  the  Liquidation  Period  as  set  forth  under  "Summary  of  Essential
Information" and terminated  at the  end of  such period.  Additionally, if  the
value  of the Trust as shown by any  Evaluation is less than forty percent (40%)
of the value of the Securities deposited in the Trust on the Date of Deposit and
thereafter, the Trustee will, if directed  by the Sponsor in writing,  terminate
the  Trust. The Trust may also be terminated  at any time by the written consent
of Unit Holders owning 51% or more  of the Units then outstanding. Unit  Holders
will  receive their final  distributions (that is,  their pro rata distributions
realized from the sale of Portfolio Securities plus any other Trust assets, less
Trust  expenses)  according  to   their  Election  Instructions.  The   Election
Instructions  will  provide for  the  following distribution  options:  (1) cash
distributions; or (2) distributions "in kind" available only to any Unit  Holder
owning  at least 2,500 Units. Unit Holders  who do not tender properly completed
Election Instructions  to the  Trustee will  be deemed  to have  elected a  cash
distribution.

                                       12
<PAGE>
    CASH  OR "IN KIND" DISTRIBUTIONS. Unit Holders holding less than 2,500 Units
will receive distributions in  respect of their Units  at termination solely  in
cash. Unit Holders holding at least 2,500 Units may indicate to the Trustee that
they  wish to receive  termination distributions "in kind",  by returning to the
Trustee properly completed Election Instructions  distributed by the Trustee  to
such  Unit Holders of record 45 days  prior to the Termination Date. The Trustee
will duly honor such election instructions  received on or before the  Mandatory
Termination  Date. Such Unit Holder will be  entitled to receive whole shares of
each of the underlying Portfolio Securities and cash from the Principal  Account
equal  to the fractional shares to which such tendering Unit Holder is entitled.
A Unit  Holder  receiving  distributions  of  Securities  "in  kind"  may  incur
brokerage  and odd-lot costs in converting Securities so received into cash. The
Trustee will transfer the Securities to be delivered in kind to the account  of,
and for disposition in accordance with the instructions of, the Unit Holder.

    METHOD  OF SECURITIES DISPOSAL. The Trustee will begin to sell the remaining
Securities held in  the Trust  on the next  business day  following the  In-Kind
Date.  Since the Trust is not managed,  Securities in the Portfolio must be sold
in accordance with the Indenture, which provides for sales over a period of days
or on any one  day during the  Liquidation Period set forth  in the "Summary  of
Essential  Information". Daily proceeds of such sales will be deposited into the
Trust, will be held in a non-interest bearing account until distributed and will
be of benefit  to the Trustee.  The sales  of Portfolio Securities  may tend  to
depress  the  market prices  for such  Securities and  thus reduce  the proceeds
available to  Unit Holders.  The Sponsor  believes that  gradual liquidation  of
Securities  during  the Liquidation  Period may  mitigate negative  market price
consequences stemming from  the trading of  large volumes of  Securities over  a
short  period of time. There can be  no assurance, however, that such procedures
will effectively mitigate any adverse price consequences of heavy volume trading
or that such procedures will produce a better price for Unit Holders than  might
have been obtained had all the Securities been sold on one particular day during
the Liquidation Period.

    The Trustee will, after deduction of brokerage charges and costs incurred in
connection  with the sale of Securities, any  fees and expenses of the Trust and
payment into  the Reserve  Account of  any amount  required for  taxes or  other
governmental  charges that may be payable by  the Trust, distribute to each Unit
Holder, upon surrender for cancellation of  its Certificate after due notice  of
such  termination, such Unit Holder's pro rata share in the Income and Principal
Accounts. The sale of Securities in the  Trust upon termination may result in  a
lower  amount than might otherwise be realized if such sale were not required at
such time. For this reason, among others,  the amount realized by a Unit  Holder
upon termination may be less than the amount paid by such Unit Holder for Units.

                       RESIGNATION, REMOVAL AND LIABILITY

REGARDING THE TRUSTEE

    The  Trustee shall be under no liability  for any action taken in good faith
in reliance on prima facie properly executed documents or for the disposition of
monies or  Securities  in  the  Trust,  nor  shall  the  Trustee  be  liable  or
responsible  in  any way  for depreciation  or  loss incurred  by reason  of the
disposition of any  Securities by  the Trustee.  However, the  Trustee shall  be
liable  for wilful misfeasance, bad faith or gross negligence in the performance
of its duties  or by reason  of its  reckless disregard of  its obligations  and
duties  under the  Indenture and  Agreement. In  the event  of a  failure of the
Sponsor to act, the Trustee may act under the Indenture and Agreement and  shall
not  be liable for any such action taken  by it in good faith. The Trustee shall
not be personally  liable for any  taxes or other  governmental charges  imposed
upon  the Trust  or in respect  of the  Securities or the  interest thereon. The
Agreement also contains other customary provisions limiting the liability of the
Trustee and providing  for the indemnification  of the Trustee  for any loss  or
claim  accruing to  it without gross  negligence, bad  faith, wilful misconduct,
wilful misfeasance or reckless disregard of its duties and obligations under the
Agreement on its part.

    The Trustee  or any  successor  may resign  by  executing an  instrument  in
writing,  filing the same with the Sponsor and  mailing a copy of such notice of
resignation to all Unit Holders then  of record. Upon receiving such notice  the
Sponsor  will use its best  efforts to appoint a  successor Trustee promptly. If
the Trustee becomes incapable of acting  or becomes bankrupt or its affairs  are
taken  over by public authorities,  or upon the determination  of the Sponsor to
remove the Trustee for any reason, either with or without cause, the Sponsor may
remove the Trustee  and appoint  a successor as  provided in  the Agreement.  If
within  30 days of the resignation of  a Trustee no successor has been appointed
or, if appointed,  has not accepted  the appointment, the  retiring Trustee  may
apply  to a court of competent jurisdiction  for the appointment of a successor.
The resignation  or  removal  of  a Trustee  becomes  effective  only  when  the
successor  Trustee accepts its appointment as such  or when a court of competent
jurisdiction appoints a successor Trustee.

REGARDING THE SPONSOR

    The Sponsor shall be under no liability to the Trust or to Unit Holders  for
taking  any action or for refraining from any action in good faith or for errors
in judgment. Nor  shall the  Sponsor be  liable or  responsible in  any way  for
depreciation  or loss incurred by reason of the disposition of any Security. The
Sponsor will,  however,  be  liable  for  its  own  wilful  misfeasance,  wilful
misconduct,  bad faith, gross negligence or reckless disregard of its duties and
obligations under the Agreement.

    If at any time the Sponsor shall resign under the Agreement or shall fail or
be incapable of performing its duties thereunder or shall become bankrupt or its
affairs are taken over by public authorities, the Agreement directs the  Trustee
to  either (1) appoint a successor Sponsor  or Sponsors at rates of compensation
deemed reasonable  by  the  Trustee  not exceeding  amounts  prescribed  by  the
Securities  and Exchange  Commission, or (2)  terminate the  Trust Indenture and
Agreement and the Trust and liquidate the Trust.The Trustee will promptly notify
Unit Holders of any such action.
