THE FUND
ICON INVESTMENT OBJECTIVE
- --------------------------------------------------------------------------------
Morgan Stanley Dean Witter U.S. Government Securities Trust (the
"Fund") is a mutual fund that seeks a high level of current income
consistent with safety of principal. There is no guarantee that the
Fund will achieve this objective.
ICON PRINCIPAL INVESTMENT STRATEGIES
- --------------------------------------------------------------------------------
The Fund will invest all of its assets in U.S. Government securities.
In making investment decisions, the Fund's "Investment Manager,"
Morgan Stanley Dean Witter Advisors Inc., considers economic
developments, interest rate trends and other factors. The Fund is not
limited as to the maturities of the U.S. Government securities in
which it may invest.
The U.S. Government securities (including zero coupon securities)
that the Fund may purchase include:
- U.S. Treasury bills, notes and bonds, all of which
are direct obligations of the U.S. Government.
- Securities (including mortgage-backed securities)
issued by agencies and instrumentalities of the
U.S. Government which are backed by the full faith
and credit of the United States. Among the agencies
and instrumentalities issuing these obligations are
the Government National Mortgage Association, the
Federal Housing Administration, and Resolution
Funding Corporation.
One type of mortgage-backed security, in which the Fund may invest,
is a mortgage pass-through security. 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 differ from conventional debt securities, which provide for
periodic payment of interest in fixed amounts and principal payments
at maturity or on specified call dates. Mortgage pass-through
securities provide for monthly payments that are a "pass-through" of
the monthly interest and principal payments made by the individual
borrowers on the pooled mortgage loans. Mortgage pass-through
securities may be collateralized by mortgages with fixed rates of
interest or adjustable rates.
Fixed-income securities are debt securities such as bonds or 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.
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 or investment
strategies it uses. For example, the Investment Manager in its
discretion may determine to use some permitted trading strategies
while not using others.

<PAGE>
ICON PRINCIPAL RISKS
- --------------------------------------------------------------------------------
The Fund's share price will fluctuate with changes in the market
value of the Fund's portfolio securities. The Fund's yield also will
vary based on the yield of the Fund's portfolio securities. Neither
the value nor the yield of the U.S. Government securities that the
Fund invests in (or the value or yield of the Fund's shares) is
guaranteed by the U.S. Government. 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. Principal risks of investing in the Fund are
associated with its U.S. Government securities, which are
fixed-income securities. All 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. (Zero coupon securities are typically subject to
greater price fluctuations than comparable securities that pay
interest.) 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. 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.
While the credit risk associated with U.S. Government securities is
minimal, the interest rate risk can be substantial. The Fund is not
limited as to the maturities of the securities in which it may
invest. Thus, a rise in the general level of interest rates may cause
the price of the Fund's portfolio securities to fall substantially.
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 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
2
<PAGE>
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.
ZERO COUPON SECURITIES. A portion of the U.S. Government securities
purchased by the Fund may be zero coupon securities with maturity
dates in each case no later than ten years from the settlement date
for the purchase of such security. Such securities are purchased at a
discount from their face amount, giving the purchaser the right to
receive their full value at maturity. The interest earned on such
securities is, implicitly, automatically compounded and paid out at
maturity. While such compounding at a constant rate eliminates the
risk of receiving lower yields upon reinvestment of interest if
prevailing interest rates decline, the owner of a zero coupon
security will be unable to participate in higher yields upon
reinvestment of interest received on interest-paying securities if
prevailing interest rates rise.
A zero coupon security pays no interest to its holder during its
life. Therefore, to the extent the Fund invests in zero coupon
securities, it will not receive current cash available for
distribution to shareholders. In addition, zero coupon securities are
subject to substantially greater price fluctuations during periods of
changing prevailing interest rates than are comparable securities
which pay interest on a current basis. Current federal tax law
requires that a holder (such as the Fund) of a zero coupon security
accrue a portion of the discount at which the security was purchased
as income each year even though the Fund receives no interest
payments in cash on the security during the year.
OTHER RISKS. The performance of the Fund also will depend on whether
or not the Investment Manager is successful in pursuing the Fund's
investment strategy.
Shares of the Fund are not bank deposits and are not guaranteed or
insured by any bank, governmental entity, or the FDIC.
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
individual and governmental issuers in which the Fund invests do not
properly process and calculate date-related information from and
after January 1, 2000. While year 2000-related computer problems
could have a negative effect on the Fund, the Investment Manager and
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. In addition, governmental data
processing
3
<PAGE>
errors may result in overall economic uncertainties. Accordingly, the
(SIDEBAR) Fund's investments may be adversely affected.

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

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.
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, Money Market Fund
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 and investment minimums, should be read
before investment.
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. Certain services normally available to shareholders of Money
Market Funds, including the check writing privilege, are 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.
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 further 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.

other than the address of the registered owner(s) or
pre-designated bank account, you will need a signature
guarantee. You can obtain a signature guarantee from 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.

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
$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.
------------------------------------------------------------
ICON 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 below, 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, payment of the sale proceeds may be
delayed for the minimum time needed to verify that the check has been
honored (not more than fifteen days from the time we receive the
check).
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.
11
<PAGE>
MARGIN ACCOUNTS. Certain restrictions may apply to Fund shares
pledged in margin accounts with Dean Witter Reynolds or another
authorized broker-dealer of Fund shares. If you hold Fund shares in
this manner, please contact your Morgan Stanley Dean Witter Financial
Advisor or other authorized financial representative for more
(SIDEBAR) details.
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)
ICON DISTRIBUTIONS
- --------------------------------------------------------------------------------
The Fund passes substantially all of its earnings from income and
capital gains along to its investors as "distributions." The Fund
earns 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
declared on each day the New York Stock Exchange is open for
business, and distributed monthly and capital gains are distributed
annually 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.
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
12
<PAGE>
- 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.
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.

CLASS A SALES CHARGES - THE COMBINED PURCHASE PRIVILEGE, RIGHT OF ACCUMULATION
AND LETTER OF INTENT.
(END SIDEBAR)
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:

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.
- Tax-exempt organizations.
- Groups organized for a purpose other than to buy mutual fund
shares.
14
<PAGE>
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.
OTHER FRONT-END 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:
- 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 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.
15
<PAGE>
- 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 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
(SIDEBAR) accounts for which any of such persons is a beneficiary.
CONTINGENT DEFERRED SALES CHARGE OR CDSC

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>
<CAPTION>

Fifth 2.0%
- --------------------------------------------------------------

- --------------------------------------------------------------
</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
16
<PAGE>
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 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.
All waivers will be granted only following the 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 also are subject to an annual
distribution (12b-1) fee of 0.75% (0.65% on amounts over $10 billion)
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 reinvestments 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.)
17
<PAGE>
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, No-Load Fund 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.
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 0.75% 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.
18
<PAGE>
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 mandatory sale or transfer restrictions on
termination) pursuant to which they pay an asset-based fee.
- Persons participating in a fee-based investment program (subject to
all of its terms and conditions, including 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 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.
