THE FUND
[GRAPHIC OMITTED]
INVESTMENT OBJECTIVE
--------------------------------
Morgan Stanley Dean Witter New Discoveries Fund seeks long-term capital growth.
[GRAPHIC OMITTED]
PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------
[sidebar]
CAPITAL GROWTH
An investment objective having the goal of selecting securities with the
potential to rise in price rather than pay out income.
[end sidebar]
The Fund will normally invest at least 65% of its total assets in a diversified
mix of common stocks of small and medium-sized companies with market
capitalizations, at the time of purchase, that fall within the range of
companies included within the Russell 2000 Index and the Standard & Poor's
Mid-Cap 400 Index. As of March 31, 2000, these market capitalizations range
between $100 million and $52 billion. When selecting investments for the Fund's
portfolio, the Fund's "Sub-Advisor," Miller Anderson & Sherrerd, LLP, focuses on
companies that, in its view, demonstrate one or more of the following
characteristics: high earnings growth rates, growth stability, rising earnings
estimates, rising profitability, attractive business models and strong cash
flow. The Sub-Advisor utilizes a quantitative screening process to identify a
list of potential investments and then applies a fundamental "bottom-up"
approach and valuation analysis in order to arrive at overall stock selection
and sector allocation. In deciding whether to sell a particular security, the
Fund's Sub-Advisor considers a number of factors including unfavorable earnings
revisions or estimates, negative fundamental information, excessive market
valuations in relation to growth prospects, changes in the issuer's financial
condition or industry position as well as general economic and market
conditions.
Common stock is a share ownership or equity interest in a corporation. It may or
may not pay dividends, as some companies reinvest all of their profits back into
their businesses, while others pay out some of their profits to shareholders as
dividends.
The Fund may purchase securities issued as part of, or a short period after,
companies' initial public offerings ("IPOs"), and may at times dispose of those
shares shortly after their acquisition.
In addition, the Fund may invest in common stocks of companies with market
capitalizations which exceed or fall below the range of companies included
within the Russell 2000 or Standard & Poor's Mid-Cap 400 Indexes, as well as in
other equity securities including preferred stocks, convertible securities, and
rights and warrants.
The Fund may also invest in options and futures and, to a limited extent, in
foreign securities.
In pursuing the Fund's investment objective, the Sub-Advisor has considerable
leeway in deciding which investments it buys, holds or sells on a day-to-day
basis -- and which
1
<PAGE>
trading or investment strategies it uses. For example, the Sub-Advisor in its
discretion may determine to use some permitted trading or investment strategies
while not using others.
[GRAPHIC OMITTED]
PRINCIPAL RISKS
--------------------------
There is no assurance that the Fund will achieve its investment objective. The
Fund's share price will fluctuate with changes in the market value of the Fund's
portfolio securities. When you sell Fund shares, they may be worth less than
what you paid for them and, accordingly, you can lose money investing in this
Fund.
Common Stocks. A principal risk of investing in the Fund is associated with its
common stock investments. In general, stock values fluctuate in response to
activities specific to the company as well as general market, economic and
political conditions. Stock prices can fluctuate widely in response to these
factors.
Small & Medium Capitalization Companies. The Fund invests in stocks of small and
medium-sized companies. Investing in securities of these companies involves
greater risk than is customarily associated with investing in larger, more
established companies. These companies' stocks may be more volatile and less
liquid than the stocks of more established companies and may be subject to more
abrupt and erratic price movements. These stocks may have returns that vary,
sometimes significantly, from the overall stock market. Often smaller and medium
capitalization companies and the industries in which they are focused are still
evolving and, while this may offer better growth potential than larger, more
established companies, it also may make them more sensitive to changing market
conditions.
Shares of IPOs. The Fund's purchase of shares issued in IPOs exposes it to the
additional risks associated with companies that have little operating history as
public companies, as well as to the risks inherent in those sectors of the
market where these new issuers operate. The market for IPO issuers has been
volatile, and share prices of certain newly-public companies have fluctuated in
significant amounts over short periods of time. In addition, the Sub-Advisor
cannot guarantee continued access to IPOs.
Other Risks. The performance of the Fund also will depend on whether the
Sub-Advisor is successful in pursuing the Fund's investment strategy. The Fund
is subject to other risks from its permissible investments including the risks
associated with convertible securities, rights and warrants, options and futures
and foreign securities. Foreign securities are subject to currency risk and
risks related to economic and political developments abroad. Risks of options
and futures include the possibility of imperfect correlation between the prices
of the options and futures and the prices of the underlying Fund securities. For
more information about these risks, see the "Additional Risk Information"
section.

Shares of the Fund are not bank deposits and are not guaranteed or insured by
the FDIC or any other government agency.

[end sidebar]
(1) Reduced for purchases of $25,000 and over.
(2) Investments that are not subject to any sales charge at the time of
purchase are subject to a contingent deferred sales charge ("CDSC") of
1.00% that will be imposed if you sell your shares within one year after
purchase, except for certain specific circumstances.
(3) The CDSC is scaled down to 1.00% during the sixth year, reaching zero
thereafter. See "Share Class Arrangements" for a complete discussion of
the CDSC.
(4) Only applicable if you sell your shares within one year after purchase.
(5) The Investment Manager has agreed to assume all operating expenses (except
for brokerage and 12b-1 fees) and waive the compensation provided in the
investment management agreement until such time as the Fund has $50
million of net assets or until six months from the date of commencement of
the Fund's operations, whichever occurs first. The expenses and fees
disclosed above do not reflect the assumption of any expenses or the
waiver of any compensation by the Investment Manager.
(6) "Other Expenses" are estimated based on expenses anticipated for the first
complete fiscal year of the Fund.

EXAMPLE
This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.
The example assumes that you invest $10,000 in the Fund, your investment has a
5% return each year, and the Fund's operating expenses remain the same. Although
your actual costs may be higher or lower, the tables below show your costs at
the end of each period based on these assumptions depending upon whether or not
you sell your shares at the end of each period.
IF YOU SOLD YOUR IF YOU HELD YOUR

Long-term shareholders of Class B and Class C may pay more in sales charges,
including distribution fees, than the economic equivalent of the maximum
front-end sales charges permitted by the NASD.
The Fund was recently organized and as of the date of this Prospectus had no
historical performance to report.

ADDITIONAL INVESTMENT STRATEGY INFORMATION
---------------------------------------------------------
This section provides additional information relating to the Fund's principal
strategies.
Other Equity Securities. Up to 35% of the Fund's total assets may be invested in
other types of equity securities including preferred stocks, convertible
securities, rights and warrants. Preferred stocks pay a fixed or variable
dividend and have a prior claim before common stocks on assets and earnings but
generally carry no voting rights. Convertible securities are securities that
generally pay interest and may be converted into common stock; these securities
may carry risks associated with both common stock and fixed-income securities.
Rights and warrants are, in effect, options to purchase equity securities for a
specific price during a fixed time period.
Options and Futures. The Fund may invest in put and call options and futures on
its portfolio securities and stock indexes. The Fund may use options and futures
to protect against a decline in the Fund's securities or an increase in prices
of securities that may be purchased.
4
<PAGE>
Foreign Securities. The Fund may invest up to 5% of its net assets in foreign
securities. This percentage limitation, however, does not apply to securities of
foreign companies that are listed in the U.S. on a national securities exchange.
Defensive Investing. The Fund may take temporary "defensive" positions that are
inconsistent with the Fund's principal investment strategies in attempting to
respond to adverse market conditions. The Fund may invest any amount of its
total assets in cash or money market instruments in a defensive posture when the
Sub-Advisor believes it is advisable to do so. Although taking a defensive
posture is designed to protect the Fund from an anticipated market downturn, it
could have the effect of reducing the benefit from any upswing in the market.
When the Fund takes a defensive position, it may not achieve its investment
objective.
Portfolio Turnover. The Fund may engage in active and frequent trading of
portfolio securities to achieve its principal investment strategies. The
portfolio turnover rate may exceed 200%. A portfolio turnover rate of 200% is
equivalent to the Fund buying and selling all of its portfolio securities two
times during the course of the year. A high portfolio turnover rate (over 100%)
could result in high brokerage costs and an increase in taxable capital gains
distributions to the Fund's shareholders. See the sections on "Distributions"
and "Tax Consequences."
The percentage limitations relating to the composition of the Fund's portfolio
apply at the time the Fund acquires an investment and refer to the Fund's net
assets, unless otherwise noted. Other than percentage limits relating to
illiquid securities, subsequent percentage changes that result from market
fluctuations will not require the Fund to sell any portfolio security. The Fund
may change its principal investment strategies without shareholder approval;
however, you would be notified of any changes.
[GRAPHIC OMITTED]
ADDITIONAL RISK INFORMATION
----------------------------------------
This section provides additional information relating to the principal risks of
investing in the Fund.
Convertible Securities. The Fund may invest in convertible securities which
subject the Fund to the risks associated with both fixed-income securities and
common stocks. Fixed-income securities are subject to two types of risk: credit
risk and interest rate risk. Credit risk refers to the possibility that the
issuer of a security will be unable to make interest payments and/or repay the
principal on its debt. Interest rate risk refers to fluctuations in the value of
a fixed-income security resulting from changes in the general level of interest
rates. When the general level of interest rates goes up, the prices of most
fixed-income securities go down. When the general level of interest rates goes
down, the prices of most fixed-income securities go up. To the extent that a
convertible security's investment value is greater than its conversion value,
its price will be likely to increase when interest rates fall and decrease when
interest rates rise,
5
<PAGE>
as with a fixed-income security. If the conversion value exceeds the investment
value, the price of the convertible security will tend to fluctuate directly
with the price of the underlying equity security. A portion of these securities
may include junk bonds, which have speculative characteristics.
Rights and Warrants. Rights and warrants have no voting rights, receive no
dividends and have no rights with respect to the assets of the issuer. Rights
and warrants may be highly volatile and are, therefore, more susceptible to a
sharp decline in value than the underlying security. They also may be less
liquid than an investment in the underlying shares.
Options and Futures. If the Fund invests in options and/or futures, its
participation in these markets would subject the Fund's portfolio to certain
risks. If the Sub-Advisor's predictions of movements in the direction of the
stock markets are inaccurate, the adverse consequences to the Fund (e.g., a
reduction in the Fund's net asset value or a reduction in the amount of income
available for distribution) may leave the Fund in a worse position than if these
strategies were not used. Other risks inherent in the use of options and futures
include, for example, the possible imperfect correlation between the price of
options and futures contracts and movements in the prices of the securities
being hedged, and the possible absence of a liquid secondary market for any
particular instrument. Certain options may be over-the-counter options which are
options negotiated with dealers; there is no secondary market for these
investments.
Foreign Securities. The Fund's investments in foreign securities may involve
risks in addition to the risks associated with domestic securities. One
additional risk is currency risk. While the price of Fund shares is quoted in
U.S. dollars, the Fund generally converts U.S. dollars to a foreign market's
local currency to purchase a security in that market. If the value of that local
currency falls relative to the U.S. dollar, the U.S. dollar value of the foreign
security will decrease. This is true even if the foreign security's local price
remains unchanged.
Foreign securities (including depository receipts) also have risks related to
economic and political developments abroad, including expropriations,
confiscatory taxation, exchange control regulation, limitations on the use or
transfer of Fund assets and any effects of foreign social, economic or political
instability. Foreign companies, in general, are not subject to the regulatory
requirements of U.S. companies and, as such, there may be less publicly
available information about these companies. Moreover, foreign accounting,
auditing and financial reporting standards generally are different from those
applicable to U.S. companies. Finally, in the event of a default of any foreign
debt obligations, it may be more difficult for the Fund to obtain or enforce a
judgment against the issuers of the securities.
Securities of foreign issuers may be less liquid than comparable securities of
U.S. issuers and, as such, their price changes may be more volatile.
Furthermore, foreign exchanges
6
<PAGE>
and broker-dealers are generally subject to less government and exchange
scrutiny and regulation than their U.S. counterparts. In addition, differences
in clearance and settlement procedures in foreign markets may occasion delays in
settlements of the Fund's trades effected in those markets.

FUND MANAGEMENT
----------------------------
[sidebar]
MORGAN STANLEY DEAN
WITTER ADVISORS INC.
The Investment Manager is widely recognized as a leader in the mutual fund
industry and together with Morgan Stanley Dean Witter Services Company Inc.,
its wholly-owned subsidiary, had approximately $150 billion in assets under
management as of June 30, 2000.
[end sidebar]
The Fund has retained the Investment Manager -- Morgan Stanley Dean Witter
Advisors Inc. -- to provide administrative services and manage its business
affairs. The Investment Manager has contracted with the Sub-Advisor - Miller
Anderson & Sherrerd, LLP - to invest the Fund's assets, including the placing of
orders for the purchase and sale of portfolio securities. The Investment Manager
is a wholly-owned subsidiary of Morgan Stanley Dean Witter & Co., a preeminent
global financial services firm that maintains leading market positions in each
of its three primary businesses: securities, asset management and credit
services. Its main business office is located at Two World Trade Center, New
York, NY 10048.
The Sub-Advisor manages assets of approximately $78.4 billion as of June 30,
2000 for investment companies, employee benefit plans, endowments, foundations
and other institutional investors. The Sub-Advisor is an indirect subsidiary of
Morgan Stanley Dean Witter & Co. The Sub-Advisor's address is One Tower Bridge,
West Conshohocken, PA.
The Fund's portfolio is managed by a team of three portfolio managers: Arden C.
Armstrong, David P. Chu and Steven B. Chulik. Ms. Armstrong is a Managing
Director of the Sub-Advisor and has been managing portfolios for the Sub-Advisor
for over five years. Mr. Chu is a Principal of the Sub-Advisor and has been
affiliated with the Sub-Advisor as a portfolio manager since 1998; prior thereto
he was an analyst and portfolio manager with NationsBank and its subsidiary,
TradeStreet Investment Associates (1992-1998). Mr. Chulik is a Vice President of
the Sub-Advisor and has been affiliated with the Sub-Advisor as an analyst and
portfolio manager since 1997; prior thereto he attended the Wharton School of
the University of Pennsylvania (1995-1997), receiving an MBA.
The Fund pays the Investment Manager a monthly management fee as full
compensation for the services and facilities furnished to the Fund, and for Fund
expenses assumed by the Investment Manager. The fee is calculated at the annual
rate of 1.0% of the Fund's average daily net assets. The Investment Manager pays
the Sub-Advisor compensation equal to 40% of its compensation.

SHAREHOLDER INFORMATION
[GRAPHIC OMITTED]
PRICING FUND SHARES
-------------------------------
The price of Fund shares (excluding sales charges), called "net asset value," is
based on the value of the Fund's portfolio securities. While the assets of each
Class are invested in a single portfolio of securities, the net asset value of
each Class will differ because the Classes have different ongoing distribution
fees.
The net asset value per share of the Fund is determined once daily at 4:00 p.m.
Eastern time on each day that the New York Stock Exchange is open (or, on days
when the New York Stock Exchange closes prior to 4:00 p.m., at such earlier
time). Shares will not be priced on days that the New York Stock Exchange is
closed.
The value of the Fund's portfolio securities is based on the securities' market
price when available. When a market price is not readily available, including
circumstances under which the Investment Manager and/or Sub-Advisor determines
that a security's market price is not accurate, a portfolio security is valued
at its fair value, as determined under procedures established by the Fund's
Board of Trustees. In these cases, the Fund's net asset value will reflect
certain portfolio securities' fair value rather than their market price. With
respect to securities that are primarily listed on foreign exchanges, the value
of the Fund's portfolio securities may change on days when you will not be able
to purchase or sell your shares.
An exception to the Fund's general policy of using market prices concerns its
short-term debt portfolio securities. Debt securities with remaining maturities
of sixty days or less at the time of purchase are valued at amortized cost.
However, if the cost does not reflect the securities' market value, these
securities will be valued at their fair value.
[GRAPHIC OMITTED]
UNDERWRITING
------------------------
The Fund will initially offer its shares from approximately August 25, 2000
through September 22, 2000 in an underwriting by the Fund's Distributor, Morgan
Stanley Dean Witter Distributors Inc., as the Fund's principal underwriter.
During this period, you may place orders to buy shares through the Distributor,
however, shares will not be issued until the Closing Date, which will take place
on September 27, 2000 or on such later date as agreed upon by the Fund and the
Distributor. You are not obligated to pay for the shares prior to the Closing
Date. If any orders are accompanied by payment, the payment will be returned to
you, unless you request that such payment be invested in a Morgan Stanley Dean
Witter Money Market Fund. In such case the funds will be automatically
transferred from the Money Market Fund to the Fund on the Closing Date. You may
cancel your order to purchase shares without penalty at any time prior to the
Closing Date. A continuous offering of the Fund's shares will begin
approximately two weeks after the Closing Date.
8
<PAGE>
The Distributor will purchase Class B, Class C and Class D shares from the Fund
at $10.00 per share with all proceeds going to the Fund and will purchase Class
A shares at $10.00 per share plus a sales charge with the sales charge paid to
the Distributor and the net asset value of $10.00 per share going to the Fund.
The Distributor may also receive contingent deferred sales charges from future
redemptions of Class A, Class B and Class C shares.
During the initial offering, the Fund currently anticipates suspending the
offering of its shares to investors if its assets reach a level of approximately
$500 million.
The minimum number of Fund shares which may be purchased by any shareholder
during the initial offering period is 100 shares. Certificates for shares
purchased will not be issued unless requested by the shareholder in writing.
[GRAPHIC OMITTED]
HOW TO BUY SHARES
------------------------------
You may open a new account to buy Fund shares or buy additional Fund shares for
an existing account by contacting your Morgan Stanley Dean Witter Financial
Advisor or other authorized financial representative. Your Financial Advisor
will assist you, step-by-step, with the procedures to invest in the Fund. You
may also purchase shares directly by calling the Fund's transfer agent and
requesting an application.
[sidebar]
CONTACTING A FINANCIAL ADVISOR
If you are new to the Morgan Stanley Dean Witter Family of Funds and would like
to contact a Financial Advisor, call (877) 937-MSDW (toll-free) for the
telephone number of the Morgan Stanley Dean Witter office nearest you. You may
also access our office locator on our Internet site at:
www.msdw.com/individual/funds
[end sidebar]
Because every investor has different immediate financial needs and long-term
investment goals, the Fund offers investors four Classes of shares: Classes A,
B, C and D. Class D shares are only offered to a limited group of investors.
Each Class of shares offers a distinct structure of sales charges, distribution
and service fees, and other features that are designed to address a variety of
needs. Your Financial Advisor or other authorized financial representative can
help you decide which Class may be most appropriate for you. When purchasing
Fund shares, you must specify which Class of shares you wish to purchase.
The Fund may temporarily suspend the offering of its shares to new investors
whenever the Investment Manager and/or the Sub-Advisor determine that the Fund's
current asset level warrants such action and that a temporary suspension would
be in the best interests of shareholders. Following the suspension of offering
of shares to new investors, the Fund will continue to offer its shares to
existing shareholders and to investors participating in the Investment Manager's
mutual fund asset allocation program. The Fund may recommence offering its
shares to new investors as may be determined by the Investment Manager and/or
the Sub-Advisor consistent with prudent portfolio management.
9
<PAGE>
When you buy Fund shares, the shares are purchased at the next share price
calculated (less any applicable front-end sales charge for Class A shares) after
we receive your purchase order. Your payment is due on the third business day
after you place your purchase order. We reserve the right to reject any order
for the purchase of Fund shares.

HOW TO EXCHANGE SHARES
------------------------------------
Permissible Fund Exchanges. You may exchange shares of any Class of the Fund for
the same Class of any other continuously offered Multi-Class Fund, or for shares
of a No-Load Fund, a Money Market Fund, North American Government Income Trust
or Short-Term U.S. Treasury Trust, without the imposition of an exchange fee. In
addition, Class A shares of the Fund may be exchanged for shares of an FSC Fund
(funds subject to a front-end sales charge). See the inside back cover of this
Prospectus for each Morgan Stanley Dean Witter Fund's designation as a
Multi-Class Fund, a No-Load Fund, a Money Market Fund or FSC Fund. If a Morgan
Stanley Dean Witter Fund is not listed, consult the inside back cover of that
fund's prospectus for its designation.
Exchanges may be made after shares of the Fund acquired by purchase have been
held for thirty days. There is no waiting period for exchanges of shares
acquired by exchange or dividend reinvestment. The current prospectus for each
fund describes its investment objective(s), policies and investment minimum, and
should be read before investment. Since exchanges are available only into
continuously offered Morgan Stanley Dean Witter Funds, exchanges are not
available into any new Morgan Stanley Dean Witter Fund during its initial
offering period, or when shares of a particular Morgan Stanley Dean Witter Fund
are not being offered for purchase.
Exchange Procedures. You can process an exchange by contacting your Morgan
Stanley Dean Witter Financial Advisor or other authorized financial
representative. Otherwise, you must forward an exchange privilege authorization
form to the Fund's transfer agent -- Morgan Stanley Dean Witter Trust FSB -- and
then write the transfer agent or call (800) 869-NEWS to place an exchange order.
You can obtain an exchange privilege authorization form by contacting your
Financial Advisor or other authorized financial representative or by calling
(800) 869-NEWS. If you hold share certificates, no exchanges may be processed
until we have received all applicable share certificates.
An exchange to any Morgan Stanley Dean Witter Fund (except a Money Market Fund)
is made on the basis of the next calculated net asset values of the funds
involved after the exchange instructions are accepted. When exchanging into a
Money Market Fund, the Fund's shares are sold at their next calculated net asset
value and the Money Market Fund's shares are purchased at their net asset value
on the following business day.
The Fund may terminate or revise the exchange privilege upon required notice.
The check writing privilege is not available for Money Market Fund shares you
acquire in an exchange.
Telephone Exchanges. For your protection when calling Morgan Stanley Dean Witter
Trust FSB, we will employ reasonable procedures to confirm that exchange
instructions communicated over the telephone are genuine. These procedures may
include
11
<PAGE>
requiring various forms of personal identification such as name, mailing
address, social security or other tax identification number. Telephone
instructions also may be recorded.
Telephone instructions will be accepted if received by the Fund's transfer agent
between 9:00 a.m. and 4:00 p.m. Eastern time on any day the New York Stock
Exchange is open for business. During periods of drastic economic or market
changes, it is possible that the telephone exchange procedures may be difficult
to implement, although this has not been the case with the Fund in the past.
Margin Accounts. If you have pledged your Fund shares in a margin account,
contact your Morgan Stanely Dean Witter Financial Advisor or other authorized
financial representative regarding restrictions on the exchange of such shares.
Tax Considerations of Exchanges. If you exchange shares of the Fund for shares
of another Morgan Stanley Dean Witter Fund there are important tax
considerations. For tax purposes, the exchange out of the Fund is considered a
sale of the Fund's shares -- and the exchange into the other fund is considered
a purchase. As a result, you may realize a capital gain or loss.
You should review the "Tax Consequences" section and consult your own tax
professional about the tax consequences of an exchange.
Limitations on Exchanges. Certain patterns of past exchanges and/or purchase or
sale transactions involving the Fund or other Morgan Stanley Dean Witter Funds
may result in the Fund limiting or prohibiting, at its discretion, additional
purchases and/or exchanges. Determinations in this regard may be made based on
the frequency or dollar amount of the previous exchanges or purchase or sale
transactions. You will be notified in advance of limitations on your exchange
privileges.
CDSC Calculations on Exchanges. See the "Share Class Arrangements" section of
this Prospectus for a discussion of how applicable contingent deferred sales
charges (CDSCs) are calculated for shares of one Morgan Stanley Dean Witter Fund
that are exchanged for shares of another.

Morgan Stanley Dean Witter Financial Advisor or call (800) 869-NEWS.

o the Class of shares you wish to sell; and
o the signature of each owner as it appears on the account.
-----------------------------------------------------------------------------------------------
If you are requesting payment to anyone other than the registered owner(s) or that payment
be sent to any address other than the address of the registered owner(s) or pre-designated

an eligible guarantor acceptable to Morgan Stanley Dean Witter Trust FSB. (You should
contact Morgan Stanley Dean Witter Trust FSB at (800) 869-NEWS for a determination as to
whether a particular institution is an eligible guarantor.) A notary public cannot provide a
signature guarantee. Additional documentation may be required for shares held by a
corporation, partnership, trustee or executor.
-----------------------------------------------------------------------------------------------
Mail the letter to Morgan Stanley Dean Witter Trust FSB at P.O. Box 983, Jersey City, NJ
07303. If you hold share certificates, you must return the certificates, along with the letter
and any required additional documentation.

--------------------- -----------------------------------------------------------------------------------------------
Systematic If your investment in all of the Morgan Stanley Dean Witter Family of Funds has a total
Withdrawal Plan market value of at least $10,000, you may elect to withdraw amounts of $25 or more, or in
any whole percentage of a fund's balance (provided the amount is at least $25), on a monthly,
[GRAPHIC OMITTED] quarterly, semi-annual or annual basis, from any fund with a balance of at least $1,000. Each
time you add a fund to the plan, you must meet the plan requirements.
-----------------------------------------------------------------------------------------------
Amounts withdrawn are subject to any applicable CDSC. A CDSC may be waived under
certain circumstances. See the Class B waiver categories listed in the "Share Class
Arrangements" section of this Prospectus.
-----------------------------------------------------------------------------------------------
To sign up for the Systematic Withdrawal Plan, contact your Morgan Stanley Dean Witter
Financial Advisor or call (800) 869-NEWS. You may terminate or suspend your plan at any
time. Please remember that withdrawals from the plan are sales of shares, not Fund
"distributions," and ultimately may exhaust your account balance. The Fund may terminate or
revise the plan at any time.
--------------------- -----------------------------------------------------------------------------------------------
</TABLE>
Payment for Sold Shares. After we receive your complete instructions to sell as
described above, a check will be mailed to you within seven days, although we
will attempt to make payment within one business day. Payment may also be sent
to your brokerage account.
13
<PAGE>
Payment may be postponed or the right to sell your shares suspended under
unusual circumstances. If you request to sell shares that were recently
purchased by check, your sale will not be effected until it has been verified
that the check has been honored.
Tax Considerations. Normally, your sale of Fund shares is subject to federal and
state income tax. You should review the "Tax Consequences" section of this
Prospectus and consult your own tax professional about the tax consequences of a
sale.
Reinstatement Privilege. If you sell Fund shares and have not previously
exercised the reinstatement privilege, you may, within 35 days after the date of
sale, invest any portion of the proceeds in the same Class of Fund shares at
their net asset value and receive a pro rata credit for any CDSC paid in
connection with the sale.
Involuntary Sales. The Fund reserves the right, on sixty days' notice, to sell
the shares of any shareholder (other than shares held in an IRA or 403(b)
Custodial Account) whose shares, due to sales by the shareholder, have a value
below $100, or in the case of an account opened through EasyInvest(SM), if after
12 months the shareholder has invested less than $1,000 in the account.
However, before the Fund sells your shares in this manner, we will notify you
and allow you sixty days to make an additional investment in an amount that will
increase the value of your account to at least the required amount before the
sale is processed. No CDSC will be imposed on any involuntary sale.
Margin Accounts. If you have pledged your Fund shares in a margin account,
contact your Morgan Stanley Dean Witter Financial Advisor or other authorized
financial representative regarding restrictions on the sale of such shares.

DISTRIBUTIONS
------------------------
[sidebar]
TARGETED DIVIDENDS(SM)
You may select to have your Fund distributions automatically invested in other
Classes of Fund shares or Classes of another Morgan Stanley Dean Witter Fund
that you own. Contact your Morgan Stanley Dean Witter Financial Advisor for
further information about this service.
[end sidebar]
The Fund passes substantially all of its earnings from income and capital gains
along to its investors as "distributions." The Fund earns income from stocks and
interest from fixed-income investments. These amounts are passed along to Fund
shareholders as "income dividend distributions." The Fund realizes capital gains
whenever it sells securities for a higher price than it paid for them. These
amounts may be passed along as "capital gain distributions."
The Fund declares income dividends separately for each Class. Distributions paid
on Class A and Class D shares usually will be higher than for Class B and Class
C because distribution fees that Class B and Class C pay are higher. Normally,
income dividends are distributed to shareholders annually. Capital gains, if
any, are usually distributed in December. The Fund, however, may retain and
reinvest any long-term capital gains. The Fund may at times make payments from
sources other than income or capital gains that represent a return of a portion
of your investment.
Distributions are reinvested automatically in additional shares of the same
Class and automatically credited to your account, unless you request in writing
that all distributions be paid in cash. If you elect the cash option, the Fund
will mail a check to you no later than seven business days after the
distribution is declared. No interest will accrue on uncashed checks. However,
if you purchase Fund shares prior to the record date for the distribution, and
payment for such shares is received after the record date, the distribution will
automatically be paid to you in cash, even if you did not request to receive all
distributions in cash. If you wish to change how your distributions are paid,
your request should be received by the Fund's transfer agent, Morgan Stanley
Dean Witter Trust FSB, at least five business days prior to the record date of
the distributions.
[GRAPHIC OMITTED]
TAX CONSEQUENCES
----------------------------
As with any investment, you should consider how your Fund investment will be
taxed. The tax information in this Prospectus is provided as general
information. You should consult your own tax professional about the tax
consequences of an investment in the Fund.
Unless your investment in the Fund is through a tax-deferred retirement account,
such as a 401(k) plan or IRA, you need to be aware of the possible tax
consequences when:
o The Fund makes distributions; and
o You sell Fund shares, including an exchange to another Morgan Stanley Dean
Witter Fund.
15
<PAGE>
Taxes on Distributions. Your distributions are normally subject to federal and
state income tax when they are paid, whether you take them in cash or reinvest
them in Fund shares. A distribution also may be subject to local income tax. Any
income dividend distributions and any short-term capital gain distributions are
taxable to you as ordinary income. Any long-term capital gain distributions are
taxable as long-term capital gains, no matter how long you have owned shares in
the Fund.
Every January, you will be sent a statement (IRS Form 1099-DIV) showing the
taxable distributions paid to you in the previous year. The statement provides
information on your dividends and capital gains for tax purposes.
Taxes on Sales. Your sale of Fund shares normally is subject to federal and
state income tax and may result in a taxable gain or loss to you. A sale also
may be subject to local income tax. Your exchange of Fund shares for shares of
another Morgan Stanley Dean Witter Fund is treated for tax purposes like a sale
of your original shares and a purchase of your new shares. Thus, the exchange
may, like a sale, result in a taxable gain or loss to you and will give you a
new tax basis for your new shares.
When you open your Fund account, you should provide your Social Security or tax
identification number on your investment application. By providing this
information, you will avoid being subject to a federal backup withholding tax of
31% on taxable distributions and redemption proceeds. Any withheld amount would
be sent to the IRS as an advance tax payment.
[GRAPHIC OMITTED]
SHARE CLASS ARRANGEMENTS
-------------------------------------
The Fund offers several Classes of shares having different distribution
arrangements designed to provide you with different purchase options according
to your investment needs. Your Morgan Stanley Dean Witter Financial Advisor or
other authorized financial representative can help you decide which Class may be
appropriate for you.
The general public is offered three Classes: Class A shares, Class B shares and
Class C shares, which differ principally in terms of sales charges and ongoing
expenses. A fourth Class, Class D shares, is offered only to a limited category
of investors. Shares that you acquire through reinvested distributions will not
be subject to any front-end sales charge or CDSC -- contingent deferred sales
charge. Sales personnel may receive different compensation for selling each
Class of shares. The sales charges applicable to each Class provide for the
distribution financing of shares of that Class.
16
<PAGE>
The chart below compares the sales charge and the annual 12b-1 fees applicable
to each Class:

-----------------------------------------------------------------------------------------------------------------
</TABLE>
CLASS A SHARES Class A shares are sold at net asset value plus an initial sales
charge of up to 5.25%. The initial sales charge is reduced for purchases of
$25,000 or more according to the schedule below. Investments of $1 million or
more are not subject to an initial sales charge, but are generally subject to a
contingent deferred sales charge, or CDSC, of 1.0% on sales made within one year
after the last day of the month of purchase. The CDSC will be assessed in the
same manner and with the same CDSC waivers as with Class B shares. Class A
shares are also subject to a distribution (12b-1) fee of up to 0.25% of the
average daily net assets of the Class.
The offering price of Class A shares includes a sales charge (expressed as a
percentage of the offering price) on a single transaction as shown in the
following table:

FRONT-END SALES CHARGE OR FSC
An initial sales charge you pay when purchasing Class A shares that is based on
a percentage of the offering price. The percentage declines based upon the
dollar value of Class A shares you purchase. We offer three ways to reduce your
Class A sales charges -- the Combined Purchase Privilege, Right of Accumulation
and Letter of Intent.
[end sidebar]
17
<PAGE>
The reduced sales charge schedule is applicable to purchases of Class A shares
in a single transaction by:
o A single account (including an individual, trust or fiduciary account).
o Family member accounts (limited to husband, wife and children under the age
of 21).
o Pension, profit sharing or other employee benefit plans of companies and
their affiliates.
o Tax-exempt organizations.
o Groups organized for a purpose other than to buy mutual fund shares.
Combined Purchase Privilege. You also will have the benefit of reduced sales
charges by combining purchases of Class A shares of the Fund in a single
transaction with purchases of Class A shares of other Multi-Class Funds and
shares of FSC Funds.
Right of Accumulation. You also may benefit from a reduction of sales charges,
if the cumulative net asset value of Class A shares of the Fund purchased in a
single transaction, together with shares of other Funds you currently own which
were previously purchased at a price including a front-end sales charge
(including shares acquired through reinvestment of distributions), amounts to
$25,000 or more. Also, if you have a cumulative net asset value of all your
Class A and Class D shares equal to at least $5 million (or $25 million for
certain employee benefit plans), you are eligible to purchase Class D shares of
any Fund subject to the Fund's minimum initial investment requirement.
You must notify your Morgan Stanley Dean Witter Financial Advisor or other
authorized financial representative, (or Morgan Stanley Dean Witter Trust FSB if
you purchase directly through the Fund) at the time a purchase order is placed,
that the purchase qualifies for the reduced sales charge under the Right of
Accumulation. Similar notification must be made in writing when an order is
placed by mail. The reduced sales charge will not be granted if: (i)
notification is not furnished at the time of the order; or (ii) a review of the
records of Dean Witter Reynolds or other authorized dealer of Fund shares or the
Fund's transfer agent does not confirm your represented holdings.
Letter of Intent. The schedule of reduced sales charges for larger purchases
also will be available to you if you enter into a written "letter of intent." A
letter of intent provides for the purchase of Class A shares of the Fund or
other Multi-Class Funds or shares of FSC Funds within a thirteen-month period.
The initial purchase under a letter of intent must be at least 5% of the stated
investment goal. To determine the applicable sales charge reduction, you may
also include: (1) the cost of shares of other Morgan Stanley Dean Witter Funds
which were previously purchased at a price including a front-end sales charge
during the 90-day period prior to the distributor receiving the letter of
intent, and (2) the cost of shares of other funds you currently own acquired in
exchange
18
<PAGE>
for shares of funds purchased during that period at a price including a
front-end sales charge. You can obtain a letter of intent by contacting your
Morgan Stanley Dean Witter Financial Advisor or other authorized financial
representative, or by calling (800) 869-NEWS. If you do not achieve the stated
investment goal within the thirteen-month period, you are required to pay the
difference between the sales charges otherwise applicable and sales charges
actually paid, which may be deducted from your investment.
Other Sales Charge Waivers. In addition to investments of $1 million or more,
your purchase of Class A shares is not subject to a front-end sales charge (or a
CDSC upon sale) if your account qualifies under one of the following categories:
o A trust for which Morgan Stanley Dean Witter Trust FSB provides
discretionary trustee services.
o Persons participating in a fee-based investment program (subject to all of
its terms and conditions, including termination fees, mandatory sale or
transfer restrictions on termination) approved by the Fund's distributor
pursuant to which they pay an asset based fee for investment advisory,
administrative and/or brokerage services.
o Employer-sponsored employee benefit plans, whether or not qualified under
the Internal Revenue Code, for which Morgan Stanley Dean Witter Trust FSB
serves as trustee or Dean Witter Reynolds' Retirement Plan Services serves
as recordkeeper under a written Recordkeeping Services Agreement ("MSDW
Eligible Plans") which have at least 200 eligible employees.
o A MSDW Eligible Plan whose Class B shares have converted to Class A shares,
regardless of the plan's asset size or number of eligible employees.
o A client of a Morgan Stanley Dean Witter Financial Advisor who joined us
from another investment firm within six months prior to the date of
purchase of Fund shares, and you used the proceeds from the sale of shares
of a proprietary mutual fund of that Financial Advisor's previous firm that
imposed either a front-end or deferred sales charge to purchase Class A
shares, provided that: (1) you sold the shares not more than 60 days prior
to the purchase of Fund shares, and (2) the sale proceeds were maintained
in the interim in cash or a money market fund.
o Current or retired Directors/Trustees of the Morgan Stanley Dean Witter
Funds, such persons' spouses and children under the age of 21, and trust
accounts for which any of such persons is a beneficiary.
o Current or retired directors, officers and employees of Morgan Stanley Dean
Witter & Co. and any of its subsidiaries, such persons' spouses and
children under the age of 21, and trust accounts for which any of such
persons is a beneficiary.
19
<PAGE>
CLASS B SHARES Class B shares are offered at net asset value with no initial
sales charge but are subject to a contingent deferred sales charge, or CDSC, as
set forth in the table below. For the purpose of calculating the CDSC, shares
are deemed to have been purchased on the last day of the month during which they
were purchased.

[sidebar]
CONTINGENT DEFERRED
SALES CHARGE OR CDSC
A fee you pay when you sell shares of certain Morgan Stanley Dean Witter Funds
purchased without an initial sales charge. This fee declines the longer you hold
your shares as set forth in the table.
[end sidebar]
Each time you place an order to sell or exchange shares, shares with no CDSC
will be sold or exchanged first, then shares with the lowest CDSC will be sold
or exchanged next. For any shares subject to a CDSC, the CDSC will be assessed
on an amount equal to the lesser of the current market value or the cost of the
shares being sold.
CDSC Waivers. A CDSC, if otherwise applicable, will be waived in the case of:
o Sales of shares held at the time you die or become disabled (within the
definition in Section 72(m)(7) of the Internal Revenue Code which relates
to the ability to engage in gainful employment), if the shares are: (i)
registered either in your name (not a trust) or in the names of you and
your spouse as joint tenants with right of survivorship; or (ii) held in a
qualified corporate or self-employed retirement plan, IRA or 403(b)
Custodial Account, provided in either case that the sale is requested
within one year of your death or initial determination of disability.
o Sales in connection with the following retirement plan "distributions:" (i)
lump-sum or other distributions from a qualified corporate or self-employed
retirement plan following retirement (or, in the case of a "key employee"
of a "top heavy" plan, following attainment of age 59 1/2); (ii)
distributions from an IRA or 403(b) Custodial Account following attainment
of age 59 1/2; or (iii) a tax-free return of an excess IRA contribution (a
"distribution" does not include a direct transfer of IRA, 403(b) Custodial
Account or retirement plan assets to a successor custodian or trustee).
o Sales of shares held for you as a participant in a MSDW Eligible Plan.
o Sales of shares in connection with the Systematic Withdrawal Plan of up to
12% annually of the value of each fund from which plan sales are made. The
percentage is
20
<PAGE>
determined on the date you establish the Systematic Withdrawal Plan and
based on the next calculated share price. You may have this CDSC waiver
applied in amounts up to 1% per month, 3% per quarter, 6% semi-annually or
12% annually. Shares with no CDSC will be sold first, followed by those
with the lowest CDSC. As such, the waiver benefit will be reduced by the
amount of your shares that are not subject to a CDSC. If you suspend your
participation in the plan, you may later resume plan payments without
requiring a new determination of the account value for the 12% CDSC waiver.
o Sales of shares if you simultaneously invest the proceeds in the Investment
Manager's mutual fund asset allocation program, pursuant to which investors
pay an asset-based fee. Any shares acquired in connection with the
Investment Manager's mutual fund asset allocation program are subject to
all of the terms and conditions of that program, including termination
fees, mandatory sale or transfer restrictions on termination.
All waivers will be granted only following the Fund's distributor receiving
confirmation of your entitlement. If you believe you are eligible for a CDSC
waiver, please contact your Financial Advisor or call (800) 869-NEWS.
Distribution Fee. Class B shares are subject to an annual 12b-1 fee of 1.0% of
the average daily net assets of Class B.
Conversion Feature. After ten (10) years, Class B shares will convert
automatically to Class A shares of the Fund with no initial sales charge. The
ten year period runs from the last day of the month in which the shares were
purchased, or in the case of Class B shares acquired through an exchange, from
the last day of the month in which the original Class B shares were purchased;
the shares will convert to Class A shares based on their relative net asset
values in the month following the ten year period. At the same time, an equal
proportion of Class B shares acquired through automatically reinvested
distributions will convert to Class A shares on the same basis. (Class B shares
acquired in exchange for shares of another Morgan Stanley Dean Witter Fund
originally purchased before May 1, 1997, however, will convert to Class A shares
in May, 2007).
In the case of Class B shares held in a MSDW Eligible Plan, the plan is treated
as a single investor and all Class B shares will convert to Class A shares on
the conversion date of the Class B shares of a Morgan Stanley Dean Witter Fund
purchased by that plan.
Currently, the Class B share conversion is not a taxable event; the conversion
feature may be cancelled if it is deemed a taxable event in the future by the
Internal Revenue Service.
If you exchange your Class B shares for shares of a Money Market Fund, a No-Load
Fund, North American Government Income Trust or Short-Term U.S. Treasury Trust,
the holding period for conversion is frozen as of the last day of the month of
the exchange and resumes on the last day of the month you exchange back into
Class B shares.
21
<PAGE>
Exchanging Shares Subject to a CDSC. There are special considerations when you
exchange Fund shares that are subject to a CDSC. When determining the length of
time you held the shares and the corresponding CDSC rate, any period (starting
at the end of the month) during which you held shares of a fund that does not
charge a CDSC will not be counted. Thus, in effect the "holding period" for
purposes of calculating the CDSC is frozen upon exchanging into a fund that does
not charge a CDSC.
For example, if you held Class B shares of the Fund for one year, exchanged to
Class B of another Morgan Stanley Dean Witter Multi-Class Fund for another year,
then sold your shares, a CDSC rate of 4% would be imposed on the shares based on
a two year holding period -- one year for each fund. However, if you had
exchanged the shares of the Fund for a Money Market Fund (which does not charge
a CDSC) instead of the Multi-Class Fund, then sold your shares, a CDSC rate of
5% would be imposed on the shares based on a one year holding period. The one
year in the Money Market Fund would not be counted. Nevertheless, if shares
subject to a CDSC are exchanged for a fund that does not charge a CDSC, you will
receive a credit when you sell the shares equal to the distribution (12b-1) fees
you paid on those shares while in that fund up to the amount of any applicable
CDSC.
In addition, shares that are exchanged into or from a Morgan Stanley Dean Witter
Fund subject to a higher CDSC rate will be subject to the higher rate, even if
the shares are re-exchanged into a fund with a lower CDSC rate.
CLASS C SHARES Class C shares are sold at net asset value with no initial sales
charge but are subject to a CDSC of 1.0% on sales made within one year after the
last day of the month of purchase. The CDSC will be assessed in the same manner
and with the same CDSC waivers as with Class B shares.
Distribution Fee. Class C shares are subject to an annual distribution (12b-1)
fee of up to 1.0% of the average daily net assets of that Class. The Class C
shares' distribution fee may cause that Class to have higher expenses and pay
lower dividends than Class A or Class D shares. Unlike Class B shares, Class C
shares have no conversion feature and, accordingly, an investor that purchases
Class C shares may be subject to distribution (12b-1) fees applicable to Class C
shares for an indefinite period.
CLASS D SHARES Class D shares are offered without any sales charge on purchases
or sales and without any distribution (12b-1) fee. Class D shares are offered
only to investors meeting an initial investment minimum of $5 million ($25
million for MSDW Eligible Plans) and the following categories of investors:
22
<PAGE>
o Investors participating in the Investment Manager's mutual fund asset
allocation program (subject to all of its terms and conditions, including
termination fees, mandatory sale or transfer restrictions on termination
pursuant to which they pay an asset-based fee.
o Persons participating in a fee-based investment program (subject to all of
its terms and conditions, including termination fees, mandatory sale or
transfer restrictions on termination) approved by the Fund's distributor
pursuant to which they pay an asset based fee for investment advisory,
administrative and/or brokerage services.
o Employee benefit plans maintained by Morgan Stanley Dean Witter & Co. or
any of its subsidiaries for the benefit of certain employees of Morgan
Stanley Dean Witter & Co. and its subsidiaries.
o Certain unit investment trusts sponsored by Dean Witter Reynolds.
o Certain other open-end investment companies whose shares are distributed by
the Fund's distributor.
o Investors who were shareholders of the Dean Witter Retirement Series on
September 11, 1998 for additional purchases for their former Dean Witter
Retirement Series accounts.
Meeting Class D Eligibility Minimums. To meet the $5 million ($25 million for
MSDW Eligible Plans) initial investment to qualify to purchase Class D shares
you may combine: (1) purchases in a single transaction of Class D shares of the
Fund and other Morgan Stanley Dean Witter Multi-Class Funds; and/or (2) previous
purchases of Class A and Class D shares of Multi-Class Funds and shares of FSC
Funds you currently own, along with shares of Morgan Stanley Dean Witter Funds
you currently own that you acquired in exchange for those shares.
NO SALES CHARGES FOR REINVESTED CASH DISTRIBUTIONS If you receive a cash payment
representing an income dividend or capital gain and you reinvest that amount in
the applicable Class of shares by returning the check within 30 days of the
payment date, the purchased shares would not be subject to an initial sales
charge or CDSC.
PLAN OF DISTRIBUTION (RULE 12B-1 FEES) The Fund has adopted a Plan of
Distribution in accordance with Rule 12b-1 under the Investment Company Act of
1940 with respect to the distribution of Class A, Class B and Class C shares.
The Plan allows the Fund to pay distribution fees for the sale and distribution
of these shares. It also allows the Fund to pay for services to shareholders of
Class A, Class B and Class C shares. Because these fees are paid out of the
Fund's assets on an ongoing basis, over time these fees will increase the cost
of your investment in these Classes and may cost you more than paying other
types of sales charges.
