THE FUND
[ICON] INVESTMENT OBJECTIVE
- --------------------------------------------------------------------------------
Morgan Stanley Dean Witter Intermediate Income Securities
seeks high current income consistent with safety of
principal.
[ICON] PRINCIPAL INVESTMENT STRATEGIES
- --------------------------------------------------------------------------------
The Fund will normally invest at least 65% of its total
assets in intermediate term, investment grade fixed-income
securities. These securities may include corporate debt
securities, preferred stocks, U.S. government securities,
including mortgage-backed and zero coupon securities, and
U.S. dollar-denominated securities issued by foreign
governments or corporations. In deciding which securities to
buy, hold or sell, the Fund's "Investment Manager," Morgan
Stanley Dean Witter Advisors Inc., considers domestic and
international economic developments, interest rate trends,
bond ratings and other factors relating to the issuers. The
Fund anticipates that it will maintain an average weighted
maturity of between three to seven years; the Fund will not
invest in securities with remaining maturities greater than
twelve years.
Fixed-income securities are debt securities such as bonds
and notes. The issuer of the debt security borrows money
from the investor who buys the security. Most debt
securities pay either fixed or adjustable rates of interest
at regular intervals until they mature, at which point
investors get their principal back.
The Fund also may invest in mortgage-backed securities which
may include "pass-through" securities. These securities
represent a participation interest in a pool of residential
mortgage loans originated by U.S. Governmental or private
lenders such as banks. They provide for monthly payments
that are a "pass-through" of the monthly interest (either
fixed or adjustable rates) and principal payments made by
the individual borrowers on the pooled mortgage loans.
In addition, the Fund may invest in fixed-income securities
rated lower than investment grade.
In pursuing the Fund's investment objective, the Investment
Manager has considerable leeway in deciding which
investments it buys, holds or sells on a day-to-day basis
and which trading strategies it uses. For example, the
Investment Manager in its discretion may determine to use
some permitted trading strategies while not using others.
[ICON] 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.
FIXED-INCOME SECURITIES. A principal risk of investing in
the Fund is associated with its fixed-income investments.
All fixed-income securities are subject to two types of
risk: credit risk and interest rate risk. Credit risk refers
to the possibility
1
<PAGE>
that the issuer of a security will be unable to make
interest payments and repay the principal on its debt.
Investment grade fixed-income securities that the Fund may
hold may have speculative characteristics.
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. The Fund's
fixed-income investments may include zero coupon securities,
which are purchased at a discount and either (i) pay no
interest, or (ii) accrue interest, but make no payments
until maturity.
MORTGAGE-BACKED SECURITIES. Mortgage-backed securities in
which the Fund may invest have different risk
characteristics than traditional debt securities. Although
generally the value of fixed-income securities increases
during periods of falling interest rates and decreases
during periods of rising interest rates, this is not always
the case with mortgage-backed securities. This is due to the
fact that principal on underlying mortgages may be prepaid
at any time as well as other factors. Generally, prepayments
will increase during a period of falling interest rates and
decrease during a period of rising interest rates. The rate
of prepayments also may be influenced by economic and other
factors. Prepayment risk includes the possibility that, as
interest rates fall, securities with stated interest rates
may have the principal prepaid earlier than expected,
requiring the Fund to invest the proceeds at generally lower
interest rates.
Investments in mortgage-backed securities are made based
upon, among other things, expectations regarding the rate of
prepayments on underlying mortgage pools. Rates of
prepayment, faster or slower than expected by the Investment
Manager, could reduce the Fund's yield, increase the
volatility of the Fund and/or cause a decline in net asset
value. Certain mortgage-backed securities may be more
volatile and less liquid than other traditional types of
debt securities.
U.S. DOLLAR-DENOMINATED FOREIGN SECURITIES. The Fund's
investments in U.S. dollar-denominated foreign securities
(including depository receipts) involve risks that are in
addition to the risks associated with domestic securities.
Foreign securities 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. In particular, adverse political or economic
developments in a geographic region or a particular country
in which the Fund invests could cause a substantial decline
in value of the portfolio. 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.

ANNUAL TOTAL RETURNS
This chart shows how the performance of the Fund's Class B shares has varied
from year to year over the past 9 calendar years.
[End Sidebar]
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 and broker-dealers are generally subject to less
government and exchange scrutiny and regulation than their
U.S. counterparts.
OTHER RISKS. The performance of the Fund also will depend on
whether the Investment Manager is successful in pursuing the
Fund's investment strategy. The Fund is also subject to
other risks from its permissible investments including the
risks associated with investments in "junk bonds." 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.

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.
This example shows what expenses you could pay over time.
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.

[ICON] ADDITIONAL INVESTMENT STRATEGY INFORMATION
- --------------------------------------------------------------------------------
This section provides additional information relating to the
Fund's principal strategies.
JUNK BONDS. The Fund may invest up to 5% of its assets in
fixed-income securities rated lower than investment grade
(commonly known as "junk bonds").
DEFENSIVE INVESTING. The Fund may take temporary "defensive"
positions in attempting to respond to adverse market
conditions. The Fund may invest any amount of its assets in
cash or money market instruments in a defensive posture when
the Investment Manager 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
is not expected to exceed 200% annually under normal
circumstances. A high turnover rate, such as 200%, will
increase Fund brokerage costs. It also may increase the
Fund's capital gains, which are passed along to Fund
shareholders as distributions. This, in turn, may increase
your tax liability as a Fund shareholder. See the section 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. Subsequent percentage changes that result
from market
5
<PAGE>
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.
[ICON] ADDITIONAL RISK INFORMATION

principal risks of investing in the Fund.
FIXED-INCOME SECURITIES. As merely illustrative of the
relationship between fixed-income securities and interest
rates, the following table shows how interest rates affect
bond prices.

</TABLE>
Coupons reflect yields on Treasury securities as of
December 31, 1998. The table is not representative of price
changes for mortgage-backed securities principally because
of prepayment risk (discussed below). In addition, the table
is an illustration and does not represent expected yields or
share price changes of any Morgan Stanley Dean Witter mutual
fund.
JUNK BONDS. Fund investments in securities rated lower than
investment grade (commonly known as "junk bonds") pose
significant risks. The prices of junk bonds are likely to be
more sensitive to adverse economic changes or individual
corporate developments than higher rated securities. During
an economic downturn or substantial period of rising
interest rates, junk bond issuers and, in particular, highly
leveraged issuers may experience financial stress that would
adversely affect their ability to service their principal
and interest payment obligations, to meet their projected
business goals or to obtain additional financing. In the
event of a default, the Fund may incur additional expenses
to seek recovery. The secondary market for junk bonds may be
less liquid than the markets for higher quality securities
and, as such, may have an adverse effect on the market
prices of certain securities. Many junk bonds are issued as
Rule 144A securities. Rule 144A securities could have the
effect of increasing the level of Fund illiquidity to the
extent the Fund may be unable to find qualified
institutional buyers interested in purchasing the
securities. The illiquidity of the market may also adversely
affect the ability of the Fund's Trustees to arrive at a
fair value for certain junk bonds at certain times and could
make it difficult for the Fund to sell certain securities.
In addition, periods of economic uncertainty and change
probably would result in an increased volatility of market
prices of high yield securities. This may result in a
corresponding volatility in the Fund's net asset value.
YEAR 2000. The Fund could be adversely affected if the
computer systems necessary for the efficient operation of
the Investment Manager, the Fund's other service providers
and the markets and corporate and governmental issuers in
which the Fund invests do not properly process and calculate
date-related information from

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, has more than $134 billion in assets under management
or administration as of September 30, 1999.
[End Sidebar]
and after January 1, 2000. While year 2000-related computer
problems could have a negative effect on the Fund, the
Investment Manager and its affiliates are working hard to
avoid any problems and to obtain assurances from their
service providers that they are taking similar steps.
In addition, it is possible that the markets for securities
in which the Fund invests may be detrimentally affected by
computer failures throughout the financial services industry
beginning January 1, 2000. Improperly functioning trading
systems may result in settlement problems and liquidity
issues. Corporate and governmental data processing errors
also may result in production problems for individual
companies and overall economic uncertainties. Earnings of
individual issuers will be affected by remediation costs,
which may be substantial and may be reported inconsistently
in U.S. and foreign financial statements. Accordingly, the
Fund's investments may be adversely affected.
[ICON] FUND MANAGEMENT
- --------------------------------------------------------------------------------
The Fund has retained the Investment Manager -- Morgan
Stanley Dean Witter Advisors Inc. -- to provide
administrative services, manage its business affairs and
invest its 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, New York 10048.
The Fund's portfolio is managed within the Investment
Manager's Taxable Income Group. Rochelle G. Siegel, a Senior
Vice President of the Investment Manager, has been the
primary portfolio manager of the Fund since its inception in
May 1989 and a portfolio manager with the Investment Manager
for over five years.
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 based on the Fund's average
daily net assets. For the fiscal year ended August 31, 1999,
the Fund accrued total compensation to the Investment
Manager amounting to 0.60% of the Fund's average daily net
assets.

SHAREHOLDER INFORMATION
[ICON] 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 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. In
addition, if the Fund holds securities 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.
[ICON] 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.
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.

[ICON] 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. See the inside back cover of
this PROSPECTUS for each Morgan Stanley Dean Witter Fund's
designation as a Multi-Class Fund, No-Load Fund or Money
Market Fund. If a Morgan Stanley Dean Witter Fund is not
listed, consult the inside back cover of that Fund's
PROSPECTUS for its designation. For purposes of exchanges,
shares of FSC Funds (subject to a front-end sales charge)
are treated as Class A shares of a Multi-Class Fund.
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 minimums, 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 requiring various forms of personal
identification such as name, mailing address, social
security or other tax identification number. Telephone
instructions also may be recorded.
10
<PAGE>
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 Stanley 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 Fund 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.
FREQUENT EXCHANGES. A pattern of frequent exchanges may
result in the Fund limiting or prohibiting, at its
discretion, additional purchases and/or exchanges. The Fund
will notify you in advance of limiting 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.
For further information regarding exchange privileges, you
should contact your Morgan Stanley Dean Witter Financial
Advisor or call (800) 869-NEWS.

Systematic If your investment in all of the Morgan Stanley Dean Witter
Withdrawal Plan Family of Funds has a total market value of at least
[ICON] $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, 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.
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.

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]
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.
[ICON] DISTRIBUTIONS
- --------------------------------------------------------------------------------
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 will
usually 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 declared on each day the New
York Stock Exchange is open for business, and are
distributed to shareholders monthly. 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,
processing of your dividend checks begins immediately
following the monthly payment date, and the Fund will mail a
monthly dividend check to you normally during the first
seven days of the following month. No interest will accrue
on uncashed checks. 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.
[ICON] 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.
13
<PAGE>
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:
- The Fund makes distributions; and
- You sell Fund shares, including an exchange to another
Morgan Stanley Dean Witter Fund.
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 full 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.
[ICON] 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.
14
<PAGE>
[Sidebar]
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]
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.
The chart below compares the sales charge and maximum annual
12b-1 fee 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 4.25%. 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:
<TABLE>

-----------------------------------------------------------------------------------------
</TABLE>
The reduced sales charge schedule is applicable to purchases
of Class A shares in a single transaction by:
- A single account (including an individual, trust or
fiduciary account).
- Family member accounts (limited to husband, wife and
children under the age of 21).
- Pension, profit sharing or other employee benefit plans of
companies and their affiliates.
15
<PAGE>
- Tax-exempt organizations.
- 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 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 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.
16
<PAGE>
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 CDSC upon sale) if
your account qualifies under one of the following
categories:
- A trust for which Morgan Stanley Dean Witter Trust FSB
provides discretionary trustee services.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.

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]
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.
<TABLE>

Seventh and thereafter None
------------------------------------------------------------------------------------
</TABLE>
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:
- 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.
- 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).
- Sales of shares held for you as a participant in a MSDW
Eligible Plan.
- 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
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
18
<PAGE>
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.
- 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 you acquire 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 0.85% of the lesser of: (a) the average daily
aggregate gross purchases by all shareholders of the Fund's
Class B shares since the inception of the Fund (not
including investments of dividends or capital gains
distributions), less the average daily aggregate net asset
value of the Fund's Class B shares sold by all shareholders
since the Fund's inception upon which a CDSC has been
imposed or waived or (b) 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 held
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.
19
<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, if any, 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 0.85% 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 investor categories:
- 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.
20
<PAGE>
- 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.
- 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.
- Certain unit investment trusts sponsored by Dean Witter
Reynolds.
- Certain other open-end investment companies whose shares
are distributed by the Fund's distributor.
- 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 certain 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.
