</TABLE>
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 Global 30 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 Global 30 strategy underperformed the S&P 500
Index in certain years and there can be no assurance that the Trust will
outperform a hypothetical investment in the S&P 500 Index 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.

INVEST IN THE 10 HIGHEST YIELDING STOCKS IN EACH OF THE
DOW JONES INDUSTRIAL AVERAGE-TM-*, FINANCIAL TIMES INDEX AND HANG SENG INDEX FOR
AS LITTLE AS $1,000
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 GLOBAL SERIES 98-3, SELECT GLOBAL 30 PORTFOLIO
98-3. It is specifically designed for investors seeking income and above-average
growth potential.
PORTFOLIO SELECTION
The portfolio of the Trust consists of the 10 common stocks in each of the Dow
Jones Industrial Average, Financial Times Index and Hang Seng Index having the
highest dividend yield (on or shortly prior to the business day prior to the
date of the prospectus).
RISKS
The Trust is an unmanaged, fixed portfolio, and changes in relative dividend
yields will not cause changes to the Trust's portfolio. There are certain risks
associated with investment in common stocks, particularly foreign securities,
including price volatility resulting from factors affecting particular common
stock and the equity markets in general. Foreign securities also present
currency exchange and additional political and economic risks. The Trust helps
reduce risk because an investment is divided among 30 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. There is increased risk associated with
an investment in Hang Seng Index securities. Such securities may be considered
speculative. See the Prospectus for more complete information concerning risks.
SHORT-TERM LIFE
The Trust will terminate in approximately one year. The portfolio will then 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.
REINVESTMENT OPTION
Investors may elect to have distributions automatically reinvested in additional
units of the Trust subject to the then remaining deferred sales charge.
NO TURNOVER
The 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 Trust leaves "emotional trading" behind by focusing and buying a portfolio
of 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.
ROLLOVER OPTION
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.
