THE FUND

[GRAPHIC OMITTED]

INVESTMENT OBJECTIVE
- --------------------------------------------------
Morgan Stanley Dean Witter Hawaii Municipal Trust seeks a high level of current
income exempt from both federal and Hawaii state income taxes consistent with
the preservation of capital.


[GRAPHIC OMITTED]

PRINCIPAL INVESTMENT STRATEGIES
- ----------------------------------------------------------------
The Fund will invest at least 80% of its assets in securities that pay interest
normally exempt from federal and Hawaii state income taxes. The Fund's
"Investment Manager," Morgan Stanley Dean Witter Advisors Inc., generally
invests the Fund's assets in investment grade, municipal obligations of issuers
in Hawaii and obligations of U.S. Governmental territories such as Puerto Rico.
Municipal obligations are bonds, notes or commercial paper issued by state and
local governments. The Fund will invest in municipal obligations rated
investment grade by Moody's Investors Service or Standard & Poor's Corporation
or, if unrated, judged to be of comparable quality by the Investment Manager at
the time of purchase. There are no maturity limitations on the Fund's portfolio
securities.

(sidebar)

INCOME
An investment objective having the goal of selecting securities to pay out
income rather than rise in price.

(end sidebar)

The Fund may invest any amount of its assets in securities that pay interest
income subject to the "alternative minimum tax," and some taxpayers may have to
pay tax on a Fund distribution of this income. The Fund therefore may not be a
suitable investment for these investors. See the "Tax Consequences" section for
more details.

The Fund may invest up to 10% of its assets in inverse floating rate municipal
obligations. The interest rates on these obligations generally move in the
reverse direction of market interest rates. If market interest rates fall, the
interest rate on the obligation will increase and if market interest rates
increase, the interest rate on the obligation will fall.

Municipal obligations typically are "general obligation" or "revenue" bonds,
notes or commercial paper. General obligation securities are secured by the
issuer's faith and credit, including its taxing power for payment of principal
and interest. Revenue securities, however, are generally payable from a
specific revenue source. They are issued to fund a wide variety of public and
private projects in sectors such as public utilities, hospitals, housing,
airports and highways, and educational facilities. The Fund's municipal
obligation investments may include zero coupon securities,which are purchased
at a discount and accrue interest, but make no payment until maturity. In
addition, the Fund may invest in private activity bonds, including industrial
development and pollution control bonds, lease obligations and futures.

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 investment strategies it uses. For example, the
Investment Manager in its discretion may determine to use some permitted
investment strategies while not using others.


[GRAPHIC OMITTED]

PRINCIPAL RISKS
- -------------------------------------------
There is no assurance that the Fund will achieve its investment objective. The
Fund's share price will fluctuate with changes in the market value of the
Fund's portfolio


                                                                               1

<PAGE>



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.

CREDIT AND INTEREST RATE RISKS. A principal risk of investing in the Fund is
associated with its municipal investments, particularly its concentration in
municipal obligations of a single state. Municipal obligations, like other debt
securities, are subject to two types of risks: 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. In the
case of revenue bonds, notes or commercial paper, for example, the credit risk
is the possibility that the user fees from a project or other specified revenue
sources are insufficient to meet interest and/or principal payment obligations.
The issuers of private activity bonds, used to finance such projects as
industrial development and pollution control facilities, also may be negatively
impacted by the general credit of the user of the project. However, unlike most
fixed-income mutual funds, the Fund is subject to the added credit risk of
concentrating its investments in a single state -- Hawaii -- and its
municipalities, as well as certain U.S. territories such as Puerto Rico.
Because the Fund concentrates its investments in securities issued by Hawaii
state and local governments and certain U.S. territories, the Fund could be
affected by political, economic and regulatory developments concerning these
issuers. Should any difficulties develop concerning Hawaii or the U.S.
territories' issuers ability to pay principal and/or interest on their debt
obligations, the Fund's value and yield could be adversely affected.

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 current interest.)

The Fund is not limited as to the maturities of the municipal obligations 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.

BOND INSURANCE RISK. Many of the municipal obligations the Fund invests in will
be covered by insurance at the time of issuance or at a later date. Such
insurance covers the remaining term of the security. Insured municipal
obligations would generally be assigned a lower rating if the rating were based
primarily on the credit quality of the issuer without regard to the insurance
feature. If the claims-paying ability of the insurer were downgraded, the
ratings on the municipal obligations it insures may also be downgraded.

In addition, the Fund may invest in securities with the lowest investment grade
rating. These securities may have speculative characteristics.

NON-DIVERSIFIED STATUS. The Fund is classified as a "non-diversified" mutual
fund. The Fund therefore is permitted to have a relatively high percentage of
its assets invested in the securities of a limited number of issuers within the
state of Hawaii, and the value of its portfolio securities may be more
susceptible to any single economic, political or regulatory event than a
"diversified" mutual fund.

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. 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.

(1)  The expenses set forth in the table do not reflect that during the Fund's
     fiscal year ended November 30, 1999 (and through December 31, 2000), the
     Investment Manager has undertaken to continue to assume all operating
     expenses (except for any brokerage fees) and to waive the compensation
     provided for in its Management Agreement to the extent that they exceed
     0.55% of the Fund's daily net assets on an annualized basis. Taking the
     waiver/assumption of expenses into account, the Fund's total annual
     operating expenses would have been 0.52% for the fiscal year ended November
     30, 1999.

EXAMPLE
This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the Fund, your investment has a
5% return each year, and the Fund's operating expenses remain the same.
Although your actual costs may be higher or lower, the table below shows your
costs at the end of each period based on these assumptions.

ADDITIONAL INVESTMENT STRATEGY INFORMATION
- -------------------------------------------------------------------------------

This section provides additional information relating to the Fund's principal
strategies.

PRIVATE ACTIVITY BONDS. The Fund may invest more than 25% of its assets in
municipal obligations known as private activity bonds. These securities include
housing, industrial development and pollution control revenue, electric,
utility, manufacturing, and transportation facilities.

LEASE OBLIGATIONS. Included within the revenue bonds category are
participations in lease obligations or installment purchase contracts of
municipalities. Generally, state and local agencies or authorities issue lease
obligations to acquire equipment and facilities for public and private
purposes.

<PAGE>


FUTURES. The Fund may purchase and sell put and call futures with respect to
financial instruments and municipal bond index futures. Futures may be used to
seek to hedge against interest rate changes.

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 taxable money market instruments or the highest grade,
municipal obligations issued in other states in a defensive posture when the
Investment Manager believes it is advisable to do so. Municipal obligations of
other states pay interest that is exempt from federal income tax but not from
Hawaii state tax. Defensive investing could have the effect of reducing the
Fund's ability to provide tax-exempt income or otherwise meet its investment
objective.

ADDITIONAL RISK INFORMATION
- -----------------------------------------------------------
This section provides additional information relating to the principal risks of
investing in the Fund. As discussed in the "Principal Risks" section, a
principal risk of investing in the Fund is associated with its fixed-income
securities investments. As merely illustrative of the relationship between
fixed-income securities and interest rates, the following table shows how
interest rates affect bond prices.

yields or share price changes of any Morgan Stanley Dean Witter mutual fund.

INVERSE FLOATING RATE MUNICIPAL OBLIGATIONS. The inverse floating rate
municipal obligations in which the Fund will invest are typically created
through a division of a fixed rate municipal obligation into two separate
instruments, a short-term obligation and a long-term obligation. The interest
rate on the short-term obligation is set at periodic auctions. The interest
rate on the long-term obligation is the rate the issuer would have paid on the
fixed income obligation: (i) plus the difference between such fixed rate and
the rate on the short-term obligation, if the short-term rate is lower than the
fixed rate; or (ii) minus such difference if the interest rate on the
short-term obligation is higher than the fixed rate. Inverse floating rate
municipal obligations offer the potential for higher income than is available
from fixed rate obligations of comparable maturity and credit rating. They also
carry greater risks. In particular, the


                                                                               5

<PAGE>


prices of inverse floating rate municipal obligations are more volatile, i.e.,
they increase and decrease in response to changes in interest rates to a
greater extent than comparable fixed rate obligations.

PRIVATE ACTIVITY BONDS. The issuers of private activity bonds in which the Fund
may invest may be negatively impacted by conditions affecting either the
general credit of the user of the private activity project or the project
itself. Conditions such as regulatory and environmental restrictions and
economic downturns may lower the need for these facilities and the ability of
users of the project to pay for the facilities. This could cause a decline in
the Fund's value. The Fund's private activity bond holdings also may pay
interest subject to the alternative minimum tax. See the "Tax Consequences"
section for more details.

INDUSTRIAL DEVELOPMENT AND POLLUTION CONTROL BONDS. The Fund may invest in
industrial development and pollution control bonds (two kinds of tax-exempt
municipal bonds) whether or not the users of facilities financed by these bonds
are in the same industry. In cases where these users are in the same industry,
there may be additional risk to the Fund in the event of an economic downturn
in the industry, which may result generally in a lowered need for the
facilities and a lowered ability of the users to pay for the use of the
facilities.

LEASE OBLIGATIONS. Lease obligations may have risks not normally associated
with general obligation or other revenue bonds. Leases and installment purchase
or conditional sale contracts (which may provide for title to the leased asset
to pass eventually to the issuer) have developed as a means for governmental
issuers to acquire property and equipment without the necessity of complying
with the constitutional and statutory requirements generally applicable for the
issuance of debt. Certain lease obligations contain "non-appropriation" clauses
that provide that the governmental issuer has no obligation to make future
payments under the lease or contract unless money is appropriated for that
purpose by the appropriate legislative body on an annual or other periodic
basis. Consequently, continued lease payments on those lease obligations
containing "non-appropriation" clauses are dependent on future legislative
actions. If these legislative actions do not occur, the holders of the lease
obligation may experience difficulty in exercising their rights, including
disposition of the property.

FUTURES. If the Fund purchases or sells futures, its participation in these
markets would subject the Fund's portfolio to certain risks. The Investment
Manager's predictions of movements in the direction of interest rate markets
may be inaccurate, and the adverse consequences to the Fund (e.g., a reduction
in the Fund's net asset value or a reduction in the amount of income available
for distribution) may leave the Fund in a worse position than if these
strategies were not used. Other risks inherent in the use of futures include,
for example, the possible imperfect correlation between the price of futures
contracts and movements in the prices of the securities being hedged, and the
possible absence of a liquid secondary market for any particular instrument.
The risk of imperfect correlations may be increased by the fact that futures
contracts in which the Fund may invest are taxable securities rather than
tax-exempt securities. The prices of taxable securities may not move in a
similar manner to prices of tax-exempt securities.

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, NY 10048.

(sidebar)

MORGAN STANLEY DEAN WITTER ADVISORS INC.

The Investment Manager is widely recognized as a leader in the mutual fund
industry and together with Morgan Stanley Dean Witter Services Company Inc.,
its wholly-owned subsidiary, had approximately $145 billion in assets under
management as of December 31, 1999.

(end sidebar)

The Fund's portfolio is managed within the Investment Manager's Tax-Exempt
Fixed-Income Group. James F. Willison, a Senior Vice President and Director of
the Tax-Exempt Fixed Income Group of the Investment Manager, has been the
primary portfolio manager of the Fund since its inception and has been 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 November 30, 1999, the Fund
accrued total compensation to the Investment Manager amounting to 0.35% of the
Fund's average daily net assets. The Investment Manager has undertaken, from
January 1, 2000 through December 31, 2000, to continue to assume all operating
expenses (except for any brokerage fees) and to waive the compensation provided
for in its management agreement to the extent they exceed 0.55% of the Fund's
daily net assets on an annualized basis.


                                                                               7

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.

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 (except for short-term taxable
debt securities and certain other investments) are valued by an outside
independent pricing service. The service uses a computerized grid matrix of
tax-exempt securities and its evaluations in determining what it believes is
the fair value of the portfolio securities. The Fund's Board of Trustees
believes that timely and reliable market quotations are generally not readily
available to the Fund to value tax-exempt securities and the valuations that
the pricing service supplies are more likely to approximate the fair value of
the securities.

Short-term debt portfolio 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.

advisory, administrative and/or brokerage services, or (3) employer-sponsored

SALES CHARGES. Shares of the Fund are sold at net asset value plus an initial
sales charge of up to 3.0%. The initial sales charge is reduced for purchases
of $100,000 or more according to the schedule below. The Fund's shares are also
subject to a distribution (12b-1) fee of up to 0.20% of the average daily net
assets of the Fund.


                                                                               9

The reduced sales charge schedule is applicable to purchases of Fund shares in
a single transaction by:

o A single account (including an individual, trust or fiduciary account).

o Family member accounts (limited to husband, wife and children under the age
  of 21).

o Tax-Exempt Organizations.

o Pension, profit sharing or other employee benefit plans of companies and
  their affiliates.

o Groups organized for a purpose other than to buy mutual fund shares.

COMBINED PURCHASE PRIVILEGE. You also will have the benefit of reduced sales
charges by combining purchases of shares of the Fund in a single transaction
with purchases of Class A shares of Multi-Class Funds and shares of other FSC
Funds.

RIGHT OF ACCUMULATION. You also may benefit from a reduction of sales charges
if the cumulative net asset value of 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 $100,000 or
more.

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: (1)
notification is not furnished at the time of the order; or (2) 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.


10

<PAGE>





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 shares of the Fund or Multi-Class
Funds or shares of other 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.

SALES CHARGE WAIVERS. Your purchase of Fund shares is not subject to sales
charge if your account qualifies under one of the following categories:

o Current or retired Directors/Trustees of the Morgan Stanley Dean Witter
  Funds, such persons' spouses and children under the age of 21, and trust
  accounts for which any of such individuals is a beneficiary.

o Current or retired directors, officers and employees of Morgan Stanley Dean
  Witter & Co. and any of its subsidiaries, such persons' spouses and children
  under the age of 21, and trust accounts for which any of such individuals is
  a beneficiary.

PLAN OF DISTRIBUTION The Fund has adopted a Plan of Distribution in accordance
with Rule 12b-1 under the Investment Company Act of 1940. The Plan allows the
Fund to pay distribution fees of 0.20% for the distribution of these shares. It
also allows the Fund to pay for services to shareholders. 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 and may cost you more than paying other
types of sales charges.


[GRAPHIC OMITTED]

HOW TO EXCHANGE SHARES
- -------------------------------------------------------
PERMISSIBLE FUND EXCHANGES. You may exchange shares of the Fund (a FSC Fund)
for Class A shares of any 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


                                                                              11

<PAGE>

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.

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.


12

<PAGE>

LIMITATIONS ON EXCHANGES. Certain patterns of exchanges may result in the Fund
limiting or prohibiting, at its discretion, additional purchases and/or
exchanges. Determinations in this regard may be made based on the frequency or
dollar amount of previous exchanges. The Fund will notify you in advance of
limiting your exchange privileges.

For further information regarding exchange privileges, you should contact your
Morgan Stanley Dean Witter Financial Advisor or call (800) 869-NEWS.

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.

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 Fund shares at their net asset
value.

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.

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 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.

[GRAPHIC OMITTED]

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."

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 June and 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.

(sidebar)

TARGETED DIVIDENDS(SM)
You may select to have your Fund distributions automatically invested in
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)

Distributions are reinvested automatically in additional shares of the Fund 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.


[GRAPHIC OMITTED]

TAX CONSEQUENCES
- ----------------------------------------------
As with any investment, you should consider how your Fund investment will be
taxed. The tax information in this Prospectus is provided as general
information. You should consult your own tax professional about the tax
consequences of an investment in the Fund.

You need to be aware of the possible tax consequences when:

o The Fund makes distributions; and

o You sell Fund shares, including an exchange to another Morgan Stanley Dean
  Witter Fund.

TAXES ON DISTRIBUTIONS. Your income dividend distributions are normally exempt
from federal and Hawaii state personal income taxes -- to the extent they are
derived from Hawaii municipal obligations or obligations of U.S. Governmental
territories. Income derived from other portfolio securities may be subject to
federal, state and/or local income taxes.

Income derived from some municipal securities is subject to the federal
"alternative minimum tax." Certain tax-exempt securities whose proceeds are
used to finance private, for-profit organizations are subject to this special
tax system that ensures that individuals pay at least some federal taxes.
Although interest on these securities is generally exempt from federal income
tax, some taxpayers who have many tax deductions or exemptions nevertheless may
have to pay tax on the income.


                                                                              15

<PAGE>


If the Fund makes any capital gain distributions, those distributions will
normally be subject to federal and state income tax when they are paid, whether
you take them in cash or reinvest them in Fund shares. Any short-term capital
gain distributions are taxable to you as ordinary income. Any long-term capital
gain distributions are taxable to you as long-term capital gains, no matter how
long you have owned shares in the Fund.

The Fund may derive gains in part from municipal obligations the Fund purchased
below their principal or face values. All, or a portion, of these gains may be
taxable to you as ordinary income rather than capital gains.

Every January, you will be sent a statement (IRS Form 1099-DIV) showing the
distributions paid to you in the previous year. The statement provides
information on your dividends and capital gains for tax purposes.

TAXES ON SALES. Your sale of Fund shares normally is subject to federal and
state income tax and may result in a taxable gain or loss to you. A sale also
may be subject to local income tax. Your exchange of Fund shares for shares of
another Morgan Stanley Dean Witter Fund is treated for tax purposes like a sale
of your original shares and a purchase of your new shares. Thus, the exchange
may, like a sale, result in a taxable gain or loss to you and will give you a
new tax basis for your new shares.

When you open your Fund account, you should provide your social security or tax
identification number on your investment application. By providing this
information, you will avoid being subject to a federal backup withholding tax
of 31% on taxable distributions and sale proceeds. Any withheld amount would be
sent to the IRS as an advance tax payment.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the Fund's
financial performance for the life of the Fund. Certain information reflects
financial results for a single Fund share. The total returns in the table
represent the rate an investor would have earned or lost on an investment in
the Fund (assuming reinvestment of all dividends and distributions).

This information has been audited by PricewaterhouseCoopers LLP, independent
accountants, whose report, along with the Fund's financial statements, is
included in the annual report, which is available upon request.
