INVEST IN THE 10 HIGHEST YIELDING STOCKS IN THE DOW JONES
INDUSTRIAL AVERAGE-TM-*
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, Morgan
Stanley Dean Witter has developed the SELECT 10 INDUSTRIAL PORTFOLIO 99-3. It is
specifically designed for investors seeking income and above-average growth
potential.
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 April 30,
1999). The Trust helps reduce risk because an investment 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.
SHORT-TERM LIFE
The Trust will terminate in approximately one year. The portfolio will then
either be liquidated or distributed to unitholders in-kind at their election.
You may, of course, sell or redeem your Units prior to the Trust's termination.
Although the Trust is a one year investment, the strategy is long term.
Investors should consider reinvesting in successive trusts, for example, for at
least three to five years, to take advantage of the long term strategy.
NO TURNOVER
The Trust typically has no turnover during its life. Unitholders know exactly
where their money is invested. Managed investment portfolios may have very high
turnover rates over a one-year period.
EASY LIQUIDITY
All or a portion of your Units may be liquidated at any time, based on net asset
value (including deduction for any unpaid deferred sales charge). The price you
receive will reflect market conditions and could be more or less than the price
originally paid. Investors may at termination choose to receive their share of
the Trust's actual underlying securities.
SUITED FOR RETIREMENT ACCOUNTS
This Trust may be an attractive investment vehicle for a self-directed IRA or
self-employed retirement plan ("Keogh plan"). Unless held in an IRA or other
tax-deferred vehicle there may be current tax consequences associated with an
investment in this type of unit investment trust. As an income- and
growth-oriented investment it may be a suitable complement to help achieve
overall portfolio diversification.
NO MARKET TIMING
The Select 10 Industrial Portfolio leaves "emotional trading" behind by focusing
and buying a quality portfolio of blue-chip stocks with high dividend yields.
Due to the Trust's "buy and hold" strategy, an investor's money is generally
invested at all times. Managed investment vehicles buy and sell securities and
may have a sizable percentage of assets in cash.
REINVESTMENT OPTION
Investors may elect to have distributions automatically reinvested in additional
units of the Trust subject to the then remaining deferred sales charge.
ROLLOVER OPTIONS
Investors, in connection with the Trust's termination, may elect to roll over
their investment into units of a new series, if offered, subject only to the
deferred sales charge. There are two rollover options available to investors.
(1) The TAX-DEFERRED ROLLOVER feature enables
investors to defer any capital gains/losses on stocks which are carried over
into the new portfolio.
(2) If an investor prefers not to defer tax consequences,
or is holding his investment in a qualified account (e.g.,
IRA-2000-Registered Trademark-), an investor may elect TRADITIONAL, NON-DEFERRED
ROLLOVER.
MORGAN STANLEY DEAN WITTER DIRECT INVEST-SM-
DIRECT INVEST is an automatic investment program that can help individuals
invest for their future, now. Morgan Stanley Dean Witter created DIRECT INVEST
because preparing for the future, such as financing a college education, a down
payment on a new house, or retirement, can be difficult. Through DIRECT INVEST,
regular deductions from a checking or savings account or Morgan Stanley Dean
Witter Active Assets-Registered Trademark- Accounts are used to purchase units
of the MORGAN STANLEY DEAN WITTER SELECT 10 INDUSTRIAL PORTFOLIO without writing
any checks! The program has the additional benefits of allowing investors to
choose their own investment schedule, either once a month, twice a month or
quarterly, and also to create a purchase rate that fits into their budget.
Direct Invest does not assure a profit and does not protect against loss in
declining markets.
RISKS
The Trust is an unmanaged, fixed portfolio, and changes in relative dividend
yields will not cause changes to the Trust's portfolio. Risks of investing in
common stocks such as the Trust's securities include price volatility resulting
from factors affecting particular common stock and the equity markets in
general. See the Prospectus for more complete information concerning risks.

has not participated in any way in the creation of the Trust or in the selection
of the stocks in the portfolio and has not approved any information included in

Returns shown represent price changes plus dividend returns and do not reflect
commissions incurred in buying and selling portfolio securities or taxes. Only
the Select 10 Strategy figures reflect Trust sales charges (the full sales
charge in the first year; reduced rollover sales charges thereafter), estimated
expenses and quarterly reinvestment of dividends. These returns are not
guarantees of future performance and should not be used as a predictor of
returns to be expected in connection with the Trust. The actual returns of a
particular trust or purchase of units of a trust will vary from hypothetical
strategy returns due to, among other things, timing differences and the fact
that an actual trust has sales charges, expenses and commissions. As indicated
in the above table, the Select 10 Strategy underperformed a hypothetical
investment in all of the stocks in the DJIA in certain years and there can be no
assurance that the Trust will outperform a hypothetical investment in all of the
stocks in the DJIA over the life of the Trust.
Performance data quoted represents past performance and the investment return
and principal value of an investment will fluctuate so that an investor's units,
when redeemed or sold, may be worth more or less than their original cost.
