OVERVIEW

Morgan Stanley Dean Witter Multi-State Municipal Series Trust is an open-end,
non-diversified mutual fund that consists of ten separate fund portfolios --

    Arizona Series
    California Series
    Florida Series
    Massachusetts Series
    Michigan Series
    Minnesota Series
    New Jersey Series
    New York Series
    Ohio Series
    Pennsylvania Series

A Series-by-Series summary begins on the next page. Each summary provides a
Series' investment objective, principal investment strategies, principal risks,
past performance, and fees and expenses. Morgan Stanley Dean Witter Multi-State
Municipal Series Trust is one of Morgan Stanley Dean Witter's Income Funds. This
category of mutual fund has the goal of selecting securities to pay out income
rather than rise in value.

Shares of each Series are not bank deposits and are not guaranteed or insured by
any bank, governmental entity or the FDIC.

Plan of Reorganization. On January 26, 2000, the Board of Trustees of the Fund
approved Agreements and Plans of Reorganization by and between certain of the
Fund's Series (each, a "merging Series") and certain other Morgan Stanley Dean
Witter Funds (each, an "acquiring Fund"), pursuant to which substantially all of
the assets of each merging Series would be combined with those of the acquiring
Fund and shareholders of the merging Series would become shareholders of the
acquiring Fund receiving Class D shares of the acquiring Fund equal to the value
of their holdings in the merging Series (each, a "Reorganization"). The
California Series would be merged with Morgan Stanley Dean Witter California
Tax-Free Income Fund and the New York Series would be merged with Morgan Stanley
Dean Witter New York Tax-Free Income Fund. Each of the Massachusetts Series,
Michigan Series, Minnesota Series and Ohio Series would be merged with Morgan
Stanley Dean Witter Tax Exempt Securities Trust. If these four mergers are
consummated, shareholders of the four merging Series would become shareholders
of a national tax-exempt Fund which only seeks to invest in municipal
obligations exempt from federal income tax, and not state tax.

Each Reorganization is subject to the approval of shareholders of the
applicable merging Series at a special meeting of shareholders scheduled to be
held on June 22, 2000. A proxy statement formally detailing the proposal, the
reasons for the Trustees' action and information concerning the acquiring Fund
will be distributed to shareholders of each merging Series.


                                                                               1

THE ARIZONA SERIES

[GRAPHIC OMITTED]
INVESTMENT OBJECTIVE
- --------------------
The Arizona Series seeks to provide a high level of current income exempt from
both federal and Arizona state income taxes consistent with preservation of
capital.


[GRAPHIC OMITTED]
PRINCIPAL INVESTMENT STRATEGY
- -----------------------------
(sidebar)
INCOME
An investment objective having the goal of selecting securities to pay out
income rather than rise in price.
(end sidebar)

The Arizona Series will invest at least 80% of its total assets in securities
that pay interest normally exempt from federal and Arizona state income taxes.
The Arizona Series' "Investment Manager," Morgan Stanley Dean Witter Advisors
Inc., generally invests in investment grade, Arizona municipal obligations and
obligations of U.S. Governmental territories such as Puerto Rico. The municipal
obligations may only be rated investment grade by Moody's Investors Service or
Standard & Poor's Corporation or Fitch Investors Services, LP 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 Arizona Series' portfolio
securities.

The Arizona Series 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 obligations will increase and if market interest rates
increase, the interest rate on the obligations will fall.

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

The Arizona Series may take temporary "defensive" positions in attempting to
respond to adverse market conditions. The Arizona Series may invest any amount
of its assets in taxable money market instruments or in the highest grade
municipal obligations issued in other states when the Investment Manager
believes it is advisable to do so because of a defensive posture. Municipal
obligations of other states pay interest that is normally exempt from federal
income tax but not from Arizona income taxes. Defensive investing could have the
effect of reducing the Arizona Series' ability to provide tax exempt income or
otherwise meet its investment objective.

In addition to the securities described above, the Arizona Series may also
invest in private activity bonds and lease obligations.


[GRAPHIC OMITTED]
PRINCIPAL RISKS
- ---------------
There is no assurance that the Arizona Series will achieve its investment
objective. The Series share price and yield will fluctuate with changes in the
market value of the Series portfolio securities. When you sell shares of this
Series, they may be worth less than what you paid for them and, accordingly,
you can lose money investing in this Series.

CREDIT AND INTEREST RATE RISKS. A principal risk of investing in the Arizona
Series is associated with its municipal investments, particularly its
concentration in municipal obligations of a single state. Municipal
obligations, as with all debt securities, are subject to two types of risks:
credit risk and interest rate risk. The "Additional Risk Information" section
contains a general discussion of credit and interest rate risks.

Unlike most fixed-income funds, the Arizona Series is subject to the added
credit risk of concentrating its investments in a single state -- Arizona --
and its municipalities.


2
<PAGE>

Because the Arizona Series concentrates its investments in securities issued by
Arizona state and local governments and government authorities, the Arizona
Series will be significantly affected by the political, economic and regulatory
developments concerning those issuers. Should any difficulties develop
concerning Arizona issuers ability to pay principal and/or interest on their
debt obligations, the Series' value and yield could be adversely affected.

The Arizona Series 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 Arizona Series' portfolio securities, and the Arizona
Series' share price, to fall substantially. A table in the "Additional Risk
Information" section shows how interest rates affect bonds.

The performance of the Arizona Series will depend on whether the Arizona Series
is successful in pursuing its investment strategy. The Arizona Series is also
subject to other risk from its permissible investments including the risk
associated with inverse floating rate municipal obligations, private activity
bonds and lease obligations. For more information about the risks of the
Arizona Series' investments, see the "Additional Risk Information" section.

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

THE FLORIDA SERIES


[GRAPHIC OMITTED]
INVESTMENT OBJECTIVE
- --------------------
The Florida Series seeks to provide a high level of current income exempt from
both federal income and Florida state taxes consistent with preservation of
capital.


[GRAPHIC OMITTED]
PRINCIPAL INVESTMENT STRATEGY
- -----------------------------
(sidebar)
INCOME
An investment objective having the goal of selecting securities to pay out
income rather than rise in price.
(end sidebar)

The Florida Series will invest at least 80% of its total assets in securities
that pay interest normally exempt from federal and the Florida state intangible
tax. (Florida presently does not impose an income tax on individuals.) The
Florida Series' "Investment Manager," Morgan Stanley Dean Witter Advisors Inc.,
generally invests in investment grade, Florida municipal obligations and
obligations of U.S. Governmental territories such as Puerto Rico. The municipal
obligations may only be rated investment grade by Moody's Investors Service or
Standard & Poor's Corporation or Fitch Investors Services, LP 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 Florida Series' portfolio
securities.

The Florida Series 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 obligations will increase and if market interest
rates increase, the interest rate on the obligations will fall.

The Florida Series may invest any amount of its assets in securities that pay
interest income subject to the federal "alternative minimum tax," and some
taxpayers may have to pay tax on a Florida Series distribution of this income.
The Florida Series therefore may not be a suitable investment for these
investors. See the "Tax Consequences" section for more details. The Florida
Series may take temporary "defensive" positions in attempting to respond to
adverse market conditions. The Florida Series may invest any amount of its
assets in taxable money market instruments or in the highest grade municipal
obligations issued in other states when the Investment Manager believes it is
advisable to do so because of a defensive posture. Municipal obligations of
other states pay interest that is normally exempt from federal income tax but
not from the Florida intangible tax. Defensive investing could have the effect
of reducing the Florida Series' ability to provide tax exempt income or
otherwise meet its investment objective.

In addition to the securities described above, the Florida Series may also
invest in private activity bonds and lease obligations.


[GRAPHIC OMITTED]
PRINCIPAL RISKS
- ---------------
There is no assurance that the Florida Series will achieve its investment
objective. The Series share price and yield will fluctuate with changes in the
market value of the Series portfolio securities. When you sell shares of this
Series, they may be worth less than what you paid for them and, accordingly,
you can lose money investing in this Series.

CREDIT AND INTEREST RATE RISKS. A principal risk of investing in the Florida
Series is associated with its municipal investments, particularly its
concentration in municipal obligations of a single state. Municipal
obligations, as with all debt securities, are subject to two types of risks:
credit risk and interest rate risk. The "Additional Risk Information" section
contains a general discussion of credit and interest rate risks.

Unlike most fixed-income funds, the Florida Series is subject to the added
credit risk of concentrating its investments in a single state -- Florida --
and its municipalities.


8
<PAGE>

Because the Florida Series concentrates its investments in securities issued by
Florida state and local governments and government authorities, the Florida
Series will be significantly affected by the political, economic and regulatory
developments concerning those issuers. Should any difficulties develop
concerning Florida issuers ability to pay principal and/or interest on their
debt obligations, the Series' value and yield could be adversely affected.

The Florida Series 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 Florida Series' portfolio securities, and the Florida
Series' share price, to fall substantially. A table in the "Additional Risk
Information" section shows how interest rates affect bonds.

The performance of the Florida Series will depend on whether the Florida Series
is successful in pursuing its investment strategy. The Florida Series is also
subject to other risk from its permissible investments including the risk
associated with inverse floating rate municipal obligations, private activity
bonds and lease obligations. For more information about the risks of the
Florida Series' investments, see the "Additional Risk Information" section.

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

INCOME
An investment objective having the goal of selecting securities to pay out

(end sidebar)

The Massachusetts Series will invest at least 80% of its total assets in
securities that pay interest normally exempt from federal and Massachusetts
state income taxes. The Massachusetts Series' "Investment Manager," Morgan
Stanley Dean Witter Advisors Inc., generally invests in investment grade,
Massachusetts municipal obligations and obligations of U.S. Governmental
territories such as Puerto Rico. The municipal obligations may only be rated

taxpayers may have to pay tax on a Massachusetts Series distribution of this
income. The Massachusetts Series therefore may not be a suitable investment for
these investors. See the "Tax Consequences" section for more details.

The Massachusetts Series may take temporary "defensive" positions in attempting
to respond to adverse market conditions. The Massachusetts Series may invest

"Additional Risk Information" section shows how interest rates affect bonds.

The Massachusetts Series is classified as "non-diversified" and therefore may
invest a greater percentage of its assets in the securities of individual
issuers than "diversified" mutual funds and a decline in the value of those
securities would cause the overall value of the Series to decline to a greater
degree.

The performance of the Massachusetts Series will depend on whether the
Massachusetts Series is successful in pursuing its investment strategy. The
Massachusetts Series is also subject to other risk from its permissible

EXAMPLE
This example is intended to help you compare the cost of investing in the
Michigan Series with the cost of investing in other mutual funds. The example
assumes that you invest $10,000 in the Michigan Series, your investment has a
5% return each year, and the Michigan Series' 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.

THE MINNESOTA SERIES

[GRAPHIC OMITTED]
INVESTMENT OBJECTIVE
- --------------------
The Minnesota Series seeks to provide a high level of current income exempt
from both federal and Minnesota state income taxes consistent with preservation
of capital.


[GRAPHIC OMITTED]
PRINCIPAL INVESTMENT STRATEGY
- -----------------------------
(sidebar)
INCOME
An Investment objective having the goal of selecting securities to pay out
income rather than rise in price.
(end sidebar)

The Minnesota Series will invest at least 80% of its total assets in securities
that pay interest normally exempt from federal and Minnesota state personal
income taxes. The Minnesota Series' "Investment Manager," Morgan Stanley Dean
Witter Advisors Inc., generally invests in investment grade, Minnesota municipal
obligations. The municipal obligations may only be rated investment grade by
Moody's Investors Service or Standard & Poor's Corporation or Fitch Investors
Services, LP or, if unrated, judged to be of comparable quality by the
Investment Manager at the time of purchase. While the Minnesota Series may only
invest some of its assets in non-Minnesota municipal obligations, the ability of
the Minnesota Series' to invest in such non-Minnesota municipal obligations is
limited by Minnesota tax law. There are no maturity limitations on the Minnesota
Series' portfolio securities.

The Minnesota Series 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 obligations will increase and if market
interest rates increase, the interest rate on the obligations will fall.

The Minnesota Series may invest any amount of its assets in securities that pay
interest income subject to the federal "alternative minimum tax." This income,
along with other income, may also be subject to the Minnesota alternative
minimum tax. Some taxpayers may have to pay tax on a Minnesota Series
distribution of this income. The Minnesota Series therefore may not be a
suitable investment for these investors. See the "Tax Consequences" section for
more details.

The Minnesota Series may take temporary "defensive" positions in attempting to
respond to adverse market conditions. Subject to Minnesota tax law
requirements, the Minnesota Series may invest any amount of its assets in
taxable money market instruments or in the highest grade municipal obligations
issued in other states when the Investment Manager believes it is advisable to
do so because of a defensive posture. Municipal obligations of other states pay
interest that is normally exempt from federal income tax but not from Minnesota
income tax. Defensive investing could have the effect of reducing the Minnesota
Series' ability to provide tax exempt income or otherwise meet its investment
objective.

In addition to the securities described above, the Minnesota Series may also
invest in private activity bonds and lease obligations.


[GRAPHIC OMITTED]
PRINCIPAL RISKS
- ---------------
There is no assurance that the Minnesota Series will achieve its investment
objective. The Series share price and yield will fluctuate with changes in the
market value of the Series portfolio securities. When you sell shares of this
Series, they may be worth less than what you paid for them and, accordingly,
you can lose money investing in this Series.

CREDIT AND INTEREST RATE RISKS. A principal risk of investing in the Minnesota
Series is associated with its municipal investments, particularly its
concentration in municipal obligations of a single state. Municipal
obligations, as with all debt securities, are


18
<PAGE>

subject to two types of risks: credit risk and interest rate risk. The
"Additional Risk Information" section contains a general discussion of credit
and interest rate risks.

Unlike most fixed-income funds, the Minnesota Series is subject to the added
credit risk of concentrating its investments in a single state -- Minnesota --
and its municipalities. Because the Minnesota Series concentrates its
investments in securities issued by Minnesota state and local governments and
government authorities, the Minnesota Series will be significantly affected by
the political, economic and regulatory developments concerning those issuers.
Should any difficulties develop concerning Minnesota issuers ability to pay
principal and/or interest on their debt obligations, the Series' value and
yield could be adversely affected.

The Minnesota Series 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 Minnesota Series' portfolio securities, and the
Minnesota Series' share price, to fall substantially. A table in the
"Additional Risk Information" section shows how interest rates affect bonds.

TAXATION RISK. In accordance with Minnesota legislation enacted in 1995, income
dividend distributions that would otherwise be exempt from Minnesota personal
income tax in the case of individuals, estates and trusts may become subject to
that tax if the exemption of that income were judicially determined to
discriminate against interstate commerce.

The Minnesota Series is classified as "non-diversified" and therefore may
invest a greater percentage of its assets in the securities of individual
issuers than "diversified" mutual funds and a decline in the value of those
securities would cause the overall value of the Series to decline to a greater
degree.

The performance of the Minnesota Series will depend on whether the Minnesota
Series is successful in pursuing its investment strategy. The Minnesota Series
is also subject to other risk from its permissible investments including the
risk associated with inverse floating rate municipal obligations, private
activity bonds and lease obligations. For more information about the risks of
the Minnesota Series' investments, see the "Additional Risk Information"
section.

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

5% return each year, and the New York Series' 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.

THE OHIO SERIES


[GRAPHIC OMITTED]
INVESTMENT OBJECTIVE
- --------------------
The Ohio Series seeks to provide a high level of current income exempt from
both federal and Ohio state income taxes consistent with preservation of
capital.


[GRAPHIC OMITTED]
PRINCIPAL INVESTMENT STRATEGY
- -----------------------------
(sidebar)
INCOME
An investment objective having the goal of selecting securities to pay out
income rather than rise in price.
(edn sidebar)

The Ohio Series will invest at least 80% of its total assets in securities that
pay interest normally exempt from federal and Ohio state income taxes. The Ohio
Series' "Investment Manager," Morgan Stanley Dean Witter Advisors Inc.,
generally invests in investment grade, Ohio municipal obligations and
obligations of U.S. Governmental territories such as Puerto Rico. The municipal
obligations may only be rated investment grade by Moody's Investors Service or
Standard & Poor's Corporation or Fitch Investors Services, LP 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 Ohio Series' portfolio
securities.

The Ohio Series 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 obligations will increase and if market interest
rates increase, the interest rate on the obligations will fall.

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

The Ohio Series may take temporary "defensive" positions in attempting to
respond to adverse market conditions. The Ohio Series may invest any amount of
its assets in taxable money market instruments or in the highest grade
municipal obligations issued in other states when the Investment Manager
believes it is advisable to do so because of a defensive posture. Municipal
obligations of other states pay interest that is normally exempt from federal
income tax but not from Ohio income tax. Defensive investing could have the
effect of reducing the Ohio Series' ability to provide tax exempt income or
otherwise meet its investment objective.

In addition to the securities described above, the Ohio Series may also invest
in private activity bonds and lease obligations.


[GRAPHIC OMITTED]
PRINCIPAL RISKS
- ---------------
There is no assurance that the Ohio Series will achieve its investment
objective. The Series share price and yield will fluctuate with changes in the
market value of the Series portfolio securities. When you sell shares of this
Series, they may be worth less than what you paid for them and, accordingly,
you can lose money investing in this Series.

CREDIT AND INTEREST RATE RISKS. A principal risk of investing in the Ohio
Series is associated with its municipal investments, particularly its
concentration in municipal obligations of a single state. Municipal
obligations, as with all debt securities, are subject to two types of risks:
credit risk and interest rate risk. The "Additional Risk Information" section
contains a general discussion of credit and interest rate risks.

Unlike most fixed-income funds, the Ohio Series is subject to the added credit
risk of concentrating its investments in a single state -- Ohio -- and its
municipalities. Because


28
<PAGE>

the Ohio Series concentrates its investments in securities issued by Ohio state
and local governments and government authorities, the Ohio Series will be
significantly affected by the political, economic and regulatory developments
concerning those issuers. Should any difficulties develop concerning Ohio
issuers ability to pay principal and/or interest on their debt obligations, the
Series' value and yield could be adversely affected.

The Ohio Series 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 Ohio Series' portfolio securities, and the Ohio Series' share
price, to fall substantially. A table in the "Additional Risk Information"
section shows how interest rates affect bonds.

The performance of the Ohio Series will depend on whether the Ohio Series is
successful in pursuing its investment strategy. The Ohio Series is also subject
to other risk from its permissible investments including the risk associated
with inverse floating rate municipal obligations, private activity bonds and
lease obligations. For more information about the risks of the Ohio Series'
investments, see the "Additional Risk Information" section.

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

ADDITIONAL INVESTMENT STRATEGY INFORMATION
- ------------------------------------------
This section provides additional information relating to each of the Series'
principal investments. In pursuing each Series' 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.

Each Series' policy of investing at least eighty percent of its total assets in
securities the interest on which is exempt from federal income taxes and income
taxes of the designated state is fundamental. The fundamental policies may not
be changed without shareholder approval.

The percentage limitations relating to the composition of a Series' 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 fluctuations will not require the Series to sell any portfolio security.
Except as indicated above, a Series may change its principal investment
strategies without shareholder approval; however, you would be notified of any
such changes.

MUNICIPAL OBLIGATIONS. Each Series may invest in municipal obligations, which
are securities issued by state and local governments. These securities
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 bonds, however, are generally payable from a specific revenue source.
They are issued for a wide variety of projects such as financing public
utilities, housing units, airports and highways, and schools. The Fund's
municipal obligation investments may include zero coupon securities, which are
purchased at a discount and accrue interest but make no interest payment until
maturity.

PRIVATE ACTIVITY BONDS. Each Series may invest more than 25% of its assets in
municipal obligations known as private activity bonds. These securities
include, for example, 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.

FUTURES. Each Series may purchase and sell in put and call futures with respect
to financial instruments and municipal bond indexes. Futures may be used to
seek to hedge against interest rate changes.

FUND STRUCTURE. The Fund may seek to achieve its investment objectives by
investing all of its assets in another mutual fund. The other fund would have
substantially the same investment objectives and policies as the Fund.

ADDITIONAL RISK INFORMATION
- ---------------------------
This section provides additional information relating to the principal risks of
investing in the Fund.

CREDIT AND INTEREST RATE RISK. A principal risk of investing in each Series is
associated with its fixed-income investments. All fixed-income securities, such
as municipal obligations, 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 goes down. When the general level of interest rates goes down, the
prices of most fixed-income securities goes up. (Zero coupon securities are
typically subject to greater price fluctuations than comparable securities that
pay current interest.) As merely illustrative of the relationship between
fixed-income securities and interest rates, the following table shows how
interest rates affect bond prices.

INVERSE FLOATING RATE MUNICIPAL OBLIGATIONS. The inverse floating rate
municipal obligations in which the Fund may 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


                                                                              35
<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 a
particular Series 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 Series' value. The Series' private activity bond holdings also may pay
interest subject to the federal or applicable state alternative minimum tax.
See the "Tax Consequences" section for more details.

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.

BOND INSURANCE RISK. Many of the municipal obligations that each Series 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.

NON-DIVERSIFIED STATUS. Each Series is classified as "non-diversified" and, as
such, its investments are not required to meet certain diversification
requirements under federal law. Compared with "diversified" funds, each Series
may invest a greater percentage of its assets in the securities of an
individual issuer. Thus, each Series' assets may be concentrated in fewer
securities than other funds. A decline in the value of those investments would
cause each Series' overall value to decline to a greater degree.

FUND MANAGEMENT
- ---------------
(sidebar)
MORGAN STANLEY DEAN WITTER ADVISORS INC.
The Investment Manager is widely recognized as a leader in the mutual fund
industry and together with Morgan Stanley Dean Witter Services Company Inc.,
its wholly-owned subsidiary, had approximately $145 billion in assets under
management as of January 31, 2000.
(end sidebar)

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.

Each Series' 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 each Series since the Fund's inception and has
been a portfolio manager with the Investment Manager for over five years.

Each Series pays the Investment Manager a monthly management fee as full
compensation for the services and facilities furnished to the Series, and for
Series expenses assumed by the Investment Manager. The fee is based on each
Series' average daily net assets. For the fiscal year ended November 30, 1999,
each Series accrued total compensation to the Investment Manager amounting to
0.35% of the Series' average daily net assets.


                                                                              37

SHAREHOLDER INFORMATION


[GRAPHIC OMITTED]
PRICING SERIES SHARES
- ---------------------
The price of Series shares (excluding sales charges), called "net asset value,"
is based on the value of a Series' portfolio securities.

The net asset value per share of each Series 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.

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

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

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

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

o    Tax-Exempt Organizations.

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

COMBINED PURCHASE PRIVILEGE. You also will have the benefit of reduced sales
charges by combining purchases of shares of a Series in a single transaction
with purchases of another Series 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 a Series purchased in a single
transaction, together with shares of another Series or 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.

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


40
<PAGE>

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.

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 any Series or shares of
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.

SALES CHARGE WAIVERS. Your purchase of Fund shares is not subject to a 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 a
Series to pay distribution fees of 0.15% for the distribution of these shares.
It also allows a Series to pay for services to shareholders. Because these fees
are paid out of a Series' 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.

We reserve the right to reject any order for the purchase of Series shares.


[GRAPHIC OMITTED]
HOW TO EXCHANGE SHARES
- ----------------------
PERMISSIBLE FUND EXCHANGES. You may exchange shares of a Series for shares of
any other Series, for shares of another FSC Fund (subject to a front-end sales
charge), 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


                                                                              41
<PAGE>

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 are treated as Class A shares of a Multi-Class Fund.

Exchanges may be made after shares of a Series 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 objectives, 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 a Series' 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, a Series' 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.



42
<PAGE>

TAX CONSIDERATIONS OF EXCHANGES. If you exchange shares of a Series for shares
of another Series or another Morgan Stanley Dean Witter Fund there are
important tax considerations. For tax purposes, the exchange out of a Series is
considered a sale of Series shares -- and the exchange into the other Fund is
considered a purchase. As a result, you may realize a capital gain or loss.

You should review the "Tax Consequences" section and consult your own tax
professional about the tax consequences of an exchange.

LIMITATIONS ON EXCHANGES. Certain patterns of 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, however,
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 Series 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 Series 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. If you have pledged your Fund shares in a margin account,
contact your Morgan Stanley Dean Witter Financial Advisor or other authorized
financial representative regarding restrictions on the sale of such shares.

DISTRIBUTIONS
- -------------

(sidebar)
TARGETED DIVIDENDS(SM)
You may select to have your Series 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)

Each Series passes substantially all of its earnings from income and capital
gains along to its investors as "distributions." A Series earns interest from
fixed-income investments. These amounts are passed along to Series shareholders
as "income dividend distributions." A Series 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 income dividends are distributed to shareholders
monthly. Any capital gains are distributed in December; if a second capital gain
distribution is necessary, it is usually paid in January of the following year.
Each Series, however, may retain and reinvest any long-term capital gains. Each
Series may at times make payments from sources other than income or capital
gains that represent a return of a portion of your investment.


44
<PAGE>

Distributions are reinvested automatically in additional shares of a Series 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.

TAX CONSEQUENCES
- ----------------
As with any investment, you should consider how your Fund's investment in any
particular Fund Series 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 a particular Series.

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

o    A Series makes distributions; and

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

TAXES ON DISTRIBUTIONS. Your income dividend distributions are normally exempt
from federal and the designated state's personal income taxes -- to the extent
they are derived from that state's municipal obligations or obligations of
governments of Puerto Rico, the Virgin Islands or Guam. (With respect to the
Minnesota Series, however, income dividend distributions are generally exempt
from Minnesota personal income tax only if they are derived from Minnesota
sources, such as obligations of the State of Minnesota and its municipalities.)
Income derived from other portfolio securities may be subject to federal, state
and/or local income taxes. (Florida, however, does not impose income tax on
individuals but the Florida state intangibles tax may be imposed on municipal
obligations of other states and their municipalities.)

Income derived from some municipal securities is subject to the federal
"alternative minimum tax." Certain tax-exempt securities, the proceeds of which
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. Many states also impose an
alternative minimum tax that is based on the federal alternative minimum
taxable income and certain other items.

If you borrow money to purchase shares of any Series, the interest on the
borrowed money is generally not deductible for personal income tax purposes.

Each Series may derive gains in part from municipal obligations the Series
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.


                                                                              45
<PAGE>

If a Series 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 Series shares. (Ohio and New Jersey
Series capital gain distributions, however, are exempt from Ohio and New Jersey
state income tax, respectively.) 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 a Series. (Minnesota, New York and Pennsylvania, however, do not
distinguish between short-term and long-term capital gains.)

PENNSYLVANIA SERIES ONLY. Shares in the Pennsylvania Series may be subject to
an "intangible personal property" tax. A Pennsylvania State statute purports to
authorize most counties to impose this tax, and some counties may levy the tax
even though it is under constitutional challenge in the courts. While the
Pennsylvania Series will invest predominately in securities that would not be
subject to the tax, the remaining fraction of the Pennsylvania Series'
investments would be subject to the intangible personal property tax.

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 Series shares normally is subject to federal and
state income tax and may result in a taxable gain or loss to you. (Gains from
the sale of New Jersey Series shares, however, are exempt from New Jersey
income tax.) A sale also may be subject to local income tax. Your exchange of
Series shares for shares of another Morgan Stanley Dean Witter Fund or Series
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 each Series'
financial performance for the past 5 fiscal years. Certain information reflects
financial results for a single Series share. The total returns in the table
represent the rate an investor would have earned or lost on an investment in a
Series (assuming reinvestment of all dividends and distributions).

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