     This Proxy Statement and Prospectus is being furnished to the shareholders
of the Minnesota Series ("Minnesota Series"), a portfolio of Morgan Stanley

held in Conference Room A, Forty-Fourth Floor, Two World Trade Center, New

Proxy Statement and Prospectus will be made on or about April   , 2000.

     At the Meeting, Minnesota Series shareholders ("Shareholders") will

26, 2000 (the "Reorganization Agreement"), between Multi-State, on behalf of
Minnesota Series, and Morgan Stanley Dean Witter Tax-Exempt Securities Trust
("Tax-Exempt") pursuant to which substantially all of the assets of Minnesota
Series will be combined with those of Tax-Exempt in exchange for Class D shares
of Tax-Exempt. As a result of this transaction, Shareholders will become
shareholders of Tax-Exempt and will receive Class D shares of Tax-Exempt equal
to the value of their holdings in Minnesota Series on the date of such
transaction (the "Reorganization"). The Class D shares to be issued by
Tax-Exempt pursuant to the Reorganization (the "Tax-Exempt Shares") will be
issued at net asset value without an initial sales charge. Further information
relating to Tax-Exempt is set forth herein and in Tax-Exempt's current
Prospectus, dated February 24, 2000 ("Tax-Exempt's Prospectus"), attached to
this Proxy Statement and Prospectus and incorporated herein by reference.

     The information concerning Minnesota Series contained herein has been
supplied by Multi-State and the information concerning Tax-Exempt contained

     The Board has fixed the close of business on March 17, 2000 as the record

notice of, and to vote at, the Meeting. As of the Record Date, there were
[    ] shares of Minnesota Series issued and outstanding. Shareholders on the

     The following persons were known to own of record or beneficially 5% or

     The following persons were known to own of record or beneficially 5% or

     . As of the Record Date, the trustees and officers of Tax-Exempt, as a
group, owned less than 1% of the outstanding shares of Tax-Exempt.


PROXIES

     The enclosed form of proxy, if properly executed and returned, will be
voted in accordance with the choice specified thereon. The proxy will be voted
in favor of the Reorganization Agreement unless a choice is indicated to vote
against or to abstain from voting on the Reorganization Agreement. The Board
knows of no business, other than that set forth in the Notice of Special
Meeting of Shareholders, to be presented for consideration at the Meeting.
However, the proxy confers discretionary authority upon the persons named
therein to vote as they determine on other business, not currently
contemplated, which may come before the Meeting. Abstentions and, if
applicable, broker "non-votes" will not count as votes in favor of the
Reorganization Agreement, and broker "non-votes" will not be deemed to be
present at the meeting for purposes of determining whether the Reorganization
Agreement has been approved. Broker "non-votes" are shares held in street name
for which the broker indicates that instructions have not been received from
the beneficial owners or other persons entitled to vote and for which the
broker does not have discretionary voting authority. If a Shareholder executes
and returns a proxy but fails to indicate how the votes should be cast, the
proxy will be voted in favor of the Reorganization Agreement. The proxy may be
revoked at any time prior to the voting thereof by: (i) delivering written
notice of revocation to the Secretary of Multi-State at Two World Trade Center,
New York, New York 10048; (ii) attending the Meeting and voting in person; or
(iii) completing and returning a new proxy (whether by mail or, as discussed
below, by touchtone telephone or the Internet) (if returned and received in
time to be voted). Attendance at the Meeting will not in and of itself revoke a
proxy.

     In the event that the necessary quorum to transact business or the vote
required to approve or reject the Reorganization Agreement is not obtained at
the Meeting, the persons named as proxies may propose one or more adjournments
of the Meeting to permit further solicitation of proxies. Any such adjournment
will require the affirmative vote of the holders of a majority of shares of
Minnesota Series present in person or by proxy at the Meeting. The persons
named as proxies will vote in favor of such adjournment those proxies which
they are entitled to vote in favor of the Reorganization Agreement and will
vote against any such adjournment those proxies required to be voted against
the Reorganization Agreement.


EXPENSES OF SOLICITATION

     All expenses of this solicitation, including the cost of preparing and
mailing this Proxy Statement and Prospectus, will be borne by Minnesota Series,
which expenses are expected to approximate $60,000. Minnesota Series and
Tax-Exempt will bear all of their respective other expenses associated with the
Reorganization. In addition to the solicitation of proxies by mail, proxies may
be solicited by officers of Multi-State, and officers and regular employees of
Morgan Stanley Dean Witter Advisors Inc. ("MSDW Advisors" or the "Investment
Manager") and Morgan Stanley Dean Witter Trust FSB ("MSDW Trust"), an affiliate
of MSDW Advisors, personally or by mail, telephone, telegraph or otherwise,
without compensation therefor. Brokerage houses, banks and other fiduciaries
may be requested to forward soliciting material to the beneficial owners of
shares and to obtain authorization for the execution of proxies.


     Shareholders whose shares are registered with MSDW Trust will be able to
vote their shares by touchtone telephone or by Internet by following the
instructions on the proxy card or on the Voting Information Card


                                       2

accompanying this Proxy Statement and Prospectus. To vote by touchtone
telephone, Shareholders can call the toll-free number 1-800-690-6903. To vote
by Internet, Shareholders can access the websites www.msdwt.com or
www.proxyvote.com. Telephonic and Internet voting with MSDW Trust presently are
not available to Shareholders whose shares are held in street name.

     In certain instances, MSDW Trust, an affiliate of MSDW Advisors, may call
Shareholders to ask if they would be willing to have their votes recorded by
telephone. The telephone voting procedure is designed to authenticate
Shareholders' identities, to allow Shareholders to authorize the voting of
their shares in accordance with their instructions and to confirm that their
instructions have been recorded properly. No recommendation will be made as to
how a Shareholder should vote on the Reorganization Agreement other than to
refer to the recommendation of the Board. Multi-State, on behalf of Minnesota
Series, has been advised by counsel that these procedures are consistent with
the requirements of applicable law. Shareholders voting by telephone in this
manner will be asked for their social security number or other identifying
information and will be given an opportunity to authorize proxies to vote their
shares in accordance with their instructions. To ensure that the Shareholders'
instructions have been recorded correctly, they will receive a confirmation of
their instructions in the mail. A special toll-free number will be available in
case the information contained in the confirmation is incorrect. Although a
Shareholder's vote may be taken by telephone, each Shareholder will receive a
copy of this Proxy Statement and Prospectus and may vote by mail using the
enclosed proxy card or by touchtone telephone or the Internet as set forth
above. The last proxy vote received in time to be voted, whether by proxy card,
touchtone telephone or Internet, will be the vote that is counted and will
revoke all previous votes by the Shareholder.


VOTE REQUIRED


     Approval of the Reorganization Agreement by the Shareholders requires the
affirmative vote of a majority (i.e., more than 50%) of the shares of Minnesota
Series represented in person or by proxy and entitled to vote at the Meeting,
provided a quorum is present at the Meeting. If the Reorganization Agreement is
not approved by Shareholders, Minnesota Series will continue in existence and
the Board will consider alternative actions.


                                   SYNOPSIS


     The following is a synopsis of certain information contained in or
incorporated by reference in this Proxy Statement and Prospectus. This synopsis
is only a summary and is qualified in its entirety by the more detailed
information contained or incorporated by reference in this Proxy Statement and
Prospectus and the Reorganization Agreement. Shareholders should carefully
review this Proxy Statement and Prospectus and Reorganization Agreement in
their entirety and, in particular, Tax-Exempt's Prospectus, which is attached
to this Proxy Statement and incorporated herein by reference.


THE REORGANIZATION

     The Reorganization Agreement provides for the transfer of substantially
all the assets of Minnesota Series, subject to stated liabilities, to
Tax-Exempt in exchange for the Tax-Exempt Shares. The aggregate net asset value
of the Tax-Exempt Shares issued in the exchange will equal the aggregate value
of the net assets of Minnesota Series received by Tax-Exempt. On or after the
closing date scheduled for the Reorganization (the "Closing Date"), Minnesota
Series will distribute the Tax-Exempt Shares received by Minnesota Series to
Shareholders as of the Valuation Date (as defined below under "The
Reorganization Agreement") in complete liquidation of Minnesota Series and
Minnesota Series will thereafter be dissolved as a portfolio of Multi-State
under Massachusetts law. As a result of the Reorganization, each Shareholder
will receive that number of full and fractional Tax-Exempt Shares equal in
value to such Shareholder's pro rata interest in the net assets of Minnesota
Series transferred to Tax-Exempt. Accordingly, as a result of the
Reorganization, each Shareholder of Minnesota Series will become a holder of
Class D shares of Tax-Exempt. Shareholders holding their shares of Minnesota
Series in certificate form will be asked to surrender their certificates in
connection with the


                                       3
<PAGE>

Reorganization. Shareholders who do not surrender their certificates prior to
the Closing Date will still receive their shares of Tax-Exempt; however, such
Shareholders will not be able to redeem, transfer or exchange the Tax-Exempt
Shares received until the old certificates have been surrendered. The Board has
determined that the interests of Shareholders will not be diluted as a result
of the Reorganization.


     FOR THE REASONS SET FORTH BELOW UNDER "THE REORGANIZATION -- THE BOARD'S
CONSIDERATION," THE BOARD, INCLUDING THE TRUSTEES WHO ARE NOT "INTERESTED
PERSONS" OF MULTI-STATE, ON BEHALF OF MINNESOTA SERIES ("INDEPENDENT
TRUSTEES"), AS THAT TERM IS DEFINED IN THE INVESTMENT COMPANY ACT OF 1940, AS
AMENDED (THE "1940 ACT"), HAS CONCLUDED THAT THE REORGANIZATION IS IN THE BEST
INTERESTS OF MINNESOTA SERIES AND ITS SHAREHOLDERS AND RECOMMENDS APPROVAL OF
THE REORGANIZATION AGREEMENT.


FEE TABLE


     Minnesota Series and Tax-Exempt each pay expenses for management of their
assets, distribution of their shares and other services, and those expenses are
reflected in the net asset value per share of each fund. Class D shares of
Tax-Exempt do not pay distribution-related fees; however, the other three
Classes offered by Tax-Exempt pay fees for the distribution of their shares.
The following table briefly describes the fees and expenses that a shareholder
of Minnesota Series and a Class D shareholder of Tax-Exempt may pay if they buy
and hold shares of each respective fund. These expenses are deducted from each
respective fund's assets and are based on expenses paid by Minnesota Series for
its fiscal year ended November 30, 1999, and by Class D shares of Tax-Exempt
for its fiscal year ended December 31, 1999. The table also sets forth pro
forma fees for the surviving combined fund (Tax-Exempt) reflecting what the fee
schedule would have been on December 31, 1999, if the Reorganization had been
consummated twelve (12) months prior to that date and assuming Class D fees and
expenses.

(2)   The 12b-1 fee is accrued daily and payable monthly. The entire 12b-1 fee
      payable by Minnesota Series is characterized as a service fee within the
      meaning of National Association of Securities Dealers, Inc. ("NASD")
      guidelines and are payments made for personal service and/or maintenance
      of shareholder accounts.


EXAMPLE


     To attempt to show the effect of these expenses on an investment over
time, the hypotheticals shown below have been created. The Example assumes that
an investor invests $10,000 in either Minnesota Series or Class D shares of
Tax-Exempt or the new combined fund (Tax-Exempt), that the investment has a 5%
return each year and that the operating expenses for each fund remain the same
(as set forth in the chart above). Although a shareholder's actual costs may be
higher or lower, the tables below show a shareholder's costs at the end of each
period based on these assumptions depending upon whether or not a shareholder
sold his shares at the end of each period.

     The purpose of the foregoing fee table is to assist the investor or
shareholder in understanding the various costs and expenses that an investor or
shareholder in the fund will bear directly or indirectly. For a more complete
description of these costs and expenses, see "Comparison of Minnesota Series
and Tax-Exempt -- Investment Management and Distribution Plan Fees, Other
Significant Fees, and Purchases, Exchanges and Redemptions" below.


TAX CONSEQUENCES OF THE REORGANIZATION

     As a condition to the Reorganization, Multi-State, on behalf of Minnesota
Series, and Tax-Exempt, will receive an opinion of Mayer, Brown & Platt to the
effect that the Reorganization will constitute a tax-free reorganization for
federal income tax purposes, and that no gain or loss will be recognized by
Minnesota Series or the shareholders of Minnesota Series for federal income tax
purposes as a result of the transactions included in the Reorganization. For
further information about the tax consequences of the Reorganization, see "The
Reorganization -- Tax Aspects of the Reorganization" below.


COMPARISON OF MINNESOTA SERIES AND TAX-EXEMPT

     INVESTMENT OBJECTIVES AND POLICIES. Minnesota Series and Tax-Exempt have
partially similar investment objectives. Both Minnesota Series and Tax-Exempt
seek to provide a high level of current income exempt from federal income tax
consistent with the preservation of capital. However, Minnesota Series also
seeks, as its investment objective, a high level of current income exempt from
Minnesota state income taxes.

     Tax-Exempt seeks to achieve its investment objective by investing at least
80% of its assets in securities that pay interest exempt from federal income
taxes. Minnesota Series seeks to achieve its investment objective by investing
at least 80% of its assets in securities, the interest of which is exempt from
federal and Minnesota state income taxes. Income dividend distributions of
Tax-Exempt, to the extent derived from municipal obligations, are normally
exempt from federal income taxes. Such income dividend distributions, however,
are normally not exempt from Minnesota personal income taxes. Therefore,
shareholders of Minnesota Series who become shareholders of Tax-Exempt
generally will be subject to Minnesota personal income tax on dividend
distributions received on their Tax-Exempt Shares.

     Other than as set forth above, the investment policies of Minnesota Series
and Tax-Exempt are substantially similar; the principal differences between
them are described under "Comparison of Investment Objectives, Policies and
Restrictions" below.

     INVESTMENT MANAGEMENT AND DISTRIBUTION PLAN FEES.  Minnesota Series and
Tax-Exempt obtain management services from MSDW Advisors. With respect to
Minnesota Series, the fund pays MSDW Advisors monthly compensation calculated
daily at an annual rate of 0.35% of the fund's average daily net assets. With
respect to Tax-Exempt, the fund pays MSDW Advisors monthly compensation
calculated daily by applying the following annual rates to the average daily
net assets of the fund: 0.50% of the portion of the daily net assets not
exceeding $500 million; 0.425% of the portion of the daily net assets exceeding
$500 million but not exceeding $750 million; 0.375% of the portion of the daily
net assets exceeding $750 million but not exceeding $1 billion; 0.35% of the
portion of the daily net assets exceeding $1 billion but not exceeding $1.25
billion; and 0.325% of the portion of the daily net assets exceeding $1.25
billion. Each class of shares of Tax-Exempt is subject to the same management
fee rates.

     Multi-State has adopted a distribution plan ("Plan") pursuant to Rule
12b-1 under the 1940 Act whereby each series, including Minnesota Series,
reimburses the Distributor and others for the expenses of certain activities
and services incurred by them in connection with the distribution of each
respective series' shares. Reimbursement for these expenses is made in monthly
payments by, in this case, Minnesota Series, to the


                                       6
<PAGE>

Distributor, which will in no event exceed amounts equal to payment at the
annual rate of 0.15% of the average daily net assets of Minnesota Series. There
are no 12b-1 fees applicable to Tax-Exempt's Class D shares. For further
information relating to the 12b-1 fees applicable to each class of Tax-Exempt
shares, see the section entitled "Share Class Arrangements" in Tax-Exempt's
Prospectus, attached hereto.

     OTHER SIGNIFICANT FEES. Both Minnesota Series and Tax-Exempt pay
additional fees in connection with their operations, including legal, auditing,
transfer agent, trustees fees and custodial fees. See "Synopsis -- Fee Table"
above for the percentage of average net assets represented by such "Other
Expenses."

     PURCHASES, EXCHANGES AND REDEMPTIONS. Shares of Minnesota Series are sold
at net asset value plus an initial sales charge of up to 4.0%. The initial
sales charge is reduced for certain purchases. Shares of Minnesota Series may
be redeemed for cash without redemption or other charge at any time at the net
asset value per share next determined. Class D shares of Tax-Exempt are
currently offered at net asset value and such shares may be redeemed for cash
without redemption or other charge at the net asset value per share next
determined. Normally, Class D shares of Tax-Exempt are offered only to a
limited group of investors. Subsequent to the Reorganization, all Minnesota
Series shares will be designated Class D shares of Tax-Exempt. However,
additional investments (except for reinvestment of distributions received on
shares acquired as a result of the Reorganization) in Class D shares of
Tax-Exempt (or in Class D shares of any other Morgan Stanley Dean Witter Fund)
by Shareholders holding such shares may only be made if those Shareholders are
otherwise eligible to purchase Class D shares. Class D shares acquired in the
Reorganization may, however, be exchanged for Class D shares of another Morgan
Stanley Dean Witter Fund pursuant to Class D's exchange privileges discussed
below.

     Tax-Exempt offers four classes of shares (Class A, Class B, Class C and
Class D) which differ principally in terms of sales charges, distribution and
service fees and ongoing expenses. For further information relating to each of
the classes of Tax-Exempt's shares, see the section entitled "Share Class
Arrangements" in Tax-Exempt's Prospectus.

     Shares of Minnesota Series currently may be exchanged for shares of any
other Multi-State series, for Class A shares of any Morgan Stanley Dean Witter
Fund that offers its shares in more than one class, for shares of Morgan
Stanley Dean Witter Hawaii Municipal Trust, Morgan Stanley Dean Witter
Short-Term U.S. Treasury Trust, Morgan Stanley Dean Witter North American
Government Income Trust, Morgan Stanley Dean Witter Limited Term Municipal
Trust, Morgan Stanley Dean Witter Short-Term Bond Fund and for shares of the
five Morgan Stanley Dean Witter Funds that are money market funds. Class D
shares of Tax-Exempt may be exchanged for Class D shares of any other Morgan
Stanley Dean Witter Fund that offers its shares in more than one class, or any
of Morgan Stanley Dean Witter Short-Term U.S. Treasury Trust, Morgan Stanley
Dean Witter North American Government Income Trust, Morgan Stanley Dean Witter
Limited Term Municipal Trust, Morgan Stanley Dean Witter Short-Term Bond Fund
and the five Morgan Stanley Dean Witter Funds that are money market funds (the
foregoing funds are collectively referred to as the "Exchange Funds"), without
the imposition of an exchange fee.

     Both Minnesota Series and Tax-Exempt provide telephone exchange privileges
to their shareholders. For greater details relating to exchange privileges
applicable to Tax-Exempt, see the section entitled "How to Exchange Shares" in
Tax-Exempt's Prospectus.

     Both Minnesota Series and Tax-Exempt may redeem involuntarily, at net
asset value, most accounts valued at less than $100. However, both funds offer
a reinstatement privilege whereby a shareholder who has not previously
exercised such privilege whose shares have been redeemed or repurchased may,
within thirty-five days after the date of redemption or repurchase, reinstate
any portion or all of the proceeds thereof in shares of the same class from
which such shares were redeemed or repurchased.


                                       7
<PAGE>

     DIVIDENDS. Minnesota Series and Tax-Exempt each declare income dividends
daily and pay dividends from net investment income monthly. Both Minnesota
Series and Tax-Exempt distribute net capital gains, if any, at least annually
in December. Each, however, may determine either to distribute or to retain all
or part of any net long-term capital gains in any year for reinvestment. With
respect to both Minnesota Series and Tax-Exempt, dividends and capital gains
distributions are automatically reinvested in additional shares at net asset
value unless the shareholder elects to receive cash. As discussed above,
Tax-Exempt's income dividend distributions to shareholders are generally exempt
from federal income taxes, whereas Minnesota Series' dividend distributions are
generally exempt from federal and Minnesota state income taxes.


                            PRINCIPAL RISK FACTORS

     The share price or net asset value of Tax-Exempt and Minnesota Series will
fluctuate with changes in the market value of their respective portfolio
securities. The market value of the funds' portfolio securities will increase
or decrease due to a variety of economic, market and political factors,
including changes in prevailing interest rates, which cannot be predicted. The
principal risks of an investment in either Tax-Exempt or Minnesota Series are
the risks associated with their respective fixed-income securities which
primarily consist of municipal obligations. Fixed income 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 or unwilling to make interest payments and/or repay the principal on
its debt. In the case of certain municipal obligations known as revenue bonds,
the credit risk refers to the possibility that the user fees from a project or
specified revenue source are insufficient to meet interest and/or principal
payment obligations or the credit impairment of the user. Minnesota Series is
subject to the added credit risk of concentrating its investments in a single
state - Minnesota. Because Minnesota Series concentrates its investments in
securities issued by Minnesota state and local governments and government
authorities, Minnesota Series will be significantly affected by the political,
economic and regulatory developments concerning those issuers. Should any
difficulties develop concerning Minnesota issuers' abilities to pay principal
and/or interest on their debt obligations, the value and yield of Minnesota
Series 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.

     Unlike Tax-Exempt, Minnesota 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 such as
Tax-Exempt, Minnesota Series may invest a greater percentage of its assets in
the securities of an individual issuer. Thus, Minnesota Series' assets may be
concentrated in fewer securities than Tax-Exempt. A decline in the value of
those investments may cause Minnesota Series' overall value to decline to a
greater degree than Tax-Exempt.

     Both Tax-Exempt and Minnesota Series may invest a portion of their
respective assets in inverse floating rate municipal obligations which are
obligations that 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 rates on inverse floating rate municipal
obligations generally move in the reverse direction of market interest rates.
Inverse floating rate municipal obligations offer the potential for higher
income than is available from fixed rate obligations of comparable maturity and
credit rating but they also carry greater risks. In particular, the 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.


                                       8

     Both Tax-Exempt and Minnesota Series may invest in lease obligations and
futures which involve certain risks.

     The foregoing discussion is a summary of the principal risk factors. For a
more complete discussion of the risks of each fund, see "Principal Risks" and
"Additional Risk Information" in the Prospectus of Multi-State and in
Tax-Exempt's Prospectus attached hereto and incorporated herein by reference.


                              THE REORGANIZATION


THE PROPOSAL

     The Board of Trustees of Multi-State, on behalf of Minnesota Series,
including the Independent Trustees, having reviewed the financial position of
Minnesota Series and the prospects for achieving economies of scale through the
Reorganization and having determined that the Reorganization is in the best
interests of Minnesota Series and its Shareholders and that the interests of
Shareholders will not be diluted as a result thereof, recommends approval of
the Reorganization by Shareholders of Minnesota Series.


THE BOARD'S CONSIDERATION

     At a meeting held on January 26, 2000, the Board, including all of the
Independent Trustees, unanimously approved the Reorganization Agreement and
determined to recommend that Shareholders approve the Reorganization Agreement.
In reaching this decision, the Board made an extensive inquiry into a number of
factors, particularly the comparative expenses currently incurred in the
operations of Minnesota Series and the Class D shares of Tax-Exempt. The Board
also considered other factors, including, but not limited to: the shrinking
asset base of Minnesota Series which may affect the long-term economic
viability of the fund because of higher costs and disadvantageous economies of
scale (as of December 31, 1999, Minnesota Series had approximately $6.9 million
in net assets compared to Tax-Exempt's $1 billion in net assets); a comparison
of the differences in the investment objectives, policies, restrictions and
portfolios of Minnesota Series and Tax-Exempt particularly, that Tax-Exempt
seeks income exempt from federal income taxes, whereas Minnesota Series seeks
income exempt from both federal and Minnesota state income taxes; the terms and
conditions of the Reorganization which would affect the price of shares to be
issued in the Reorganization; the tax-free nature of the Reorganization; and
any direct or indirect costs to be incurred by Minnesota Series and Tax-Exempt
in connection with the Reorganization.

     In recommending the Reorganization to Shareholders, the Board of
Multi-State, on behalf of Minnesota Series, considered that the Reorganization
would have the following benefits to Shareholders:

     1. Once the Reorganization is consummated, the expenses which would be
borne by Class D shareholders of the "combined fund" are expected to be
significantly lower on a percentage basis than the expenses per share of
Minnesota Series although the investment management fee of Tax-Exempt is higher
than the investment management fee of Minnesota Series. The combined fund's
expenses would be lower in part because Class D shares of Tax-Exempt bear no
12b-1 fees, whereas Minnesota Series pays a 12b-1 fee of up to 0.15% of its
average net assets. Furthermore, the estimated current rate of other expenses
to be paid by Class D of the surviving Tax-Exempt (0.07% of average daily net
assets) would be lower than the rate of other expenses currently paid by
Minnesota Series (0.64% of average daily net assets). In addition, to the
extent that the Reorganization would result in Shareholders becoming
shareholders of a combined larger fund, further economies of scale could be
achieved since various fixed expenses (e.g., auditing and legal) can be spread
over a larger number of shares. The Board noted that the expense ratio for
Minnesota Series was higher (1.13% for its fiscal year ended November 30, 1999)
than the expense ratio for Class D shares of Tax-Exempt (0.51% for its fiscal
year ended December 31, 1999).


                                       9

     2. Shareholders would have the ability to exchange their Class D shares of
Tax-Exempt acquired as a result of the Reorganization into Class D shares of
any Morgan Stanley Dean Witter Multi-Class Fund. Currently, Shareholders may
only exchange into Class A shares of any Morgan Stanley Dean Witter Multi-Class
Fund. Class D shares bear lower expenses than Class A shares.

     3. The Reorganization is intended to qualify as a tax-free reorganization
for federal income tax purposes, pursuant to which no gain or loss will be
recognized by Minnesota Series or its Shareholders for Federal income tax
purposes as a result of transactions included in the Reorganization.

     The Board of Trustees of Tax-Exempt, including a majority of the
Independent Trustees of Tax-Exempt, also have determined that the
Reorganization is in the best interests of Tax-Exempt and its shareholders and
that the interests of existing shareholders of Tax-Exempt will not be diluted
as a result thereof. The transaction will enable Tax-Exempt to acquire
investment securities which are consistent with Tax-Exempt's investment
objective, without the costs attendant to the purchase of such securities in
the market. Finally, the Board considered that even if the benefits enumerated
above are not realized, the costs to the Fund are sufficiently minor to warrant
taking the opportunity to realize those benefits.


THE REORGANIZATION AGREEMENT

     The terms and conditions under which the Reorganization would be
consummated, as summarized below, are set forth in the Reorganization
Agreement. This summary is qualified in its entirety by reference to the
Reorganization Agreement, a copy of which is attached as Exhibit A to this
Proxy Statement and Prospectus.

     The Reorganization Agreement provides that (i) Minnesota Series will
transfer all of its assets, including portfolio securities, cash (other than
cash amounts retained by Minnesota Series as a "Cash Reserve" in the amount
sufficient to discharge its liabilities not discharged prior to the Valuation
Date (as defined below) and for expenses of the dissolution), cash equivalents
and receivables to Tax-Exempt on the Closing Date in exchange for the
assumption by Tax-Exempt of stated liabilities of Minnesota Series, including
all expenses, costs, charges and reserves, as reflected on an unaudited
statement of assets and liabilities of Minnesota Series prepared by the
Treasurer of Multi-State, on behalf of Minnesota Series, as of the Valuation
Date (as defined below) in accordance with generally accepted accounting
principles consistently applied from the prior audited period, and the delivery
of the Tax-Exempt Shares; (ii) such Tax-Exempt Shares would be distributed to
Shareholders on the Closing Date or as soon as practicable thereafter; (iii)
Minnesota Series would be dissolved; and (iv) the outstanding shares of
Minnesota Series would be canceled.

     The number of Tax-Exempt Shares to be delivered to Minnesota Series will
be determined by dividing the aggregate net asset value of the shares of
Minnesota Series acquired by Tax-Exempt by the net asset value per share of the
Class D shares of Tax-Exempt; these values will be calculated as of the close
of business of the New York Stock Exchange on the third business day following
the receipt of the requisite approval by Shareholders of the Reorganization
Agreement or at such other time as Minnesota Series and Tax-Exempt may agree
(the "Valuation Date"). As an illustration, assume that on the Valuation Date,
the shares of Minnesota Series had an aggregate net asset value (not including
any Cash Reserve of Minnesota Series) of $100,000. If the net asset value per
Class D share of Tax-Exempt were $10 per share at the close of business on the
Valuation Date, the number of Class D shares of Tax-Exempt to be issued would
be 10,000 ($100,000  (divided by)  $10). These 10,000 Class D shares of of
Tax-Exempt would be distributed to the former shareholders of Minnesota Series.
This example is given for illustration purposes only and does not bear any
relationship to the dollar amounts or shares expected to be involved in the
Reorganization.

     On the Closing Date or as soon as practicable thereafter, Minnesota Series
will distribute pro rata to its Shareholders of record as of the close of
business on the Valuation Date, the Tax-Exempt Shares it receives.


                                       10
<PAGE>

Each Shareholder will receive Class D shares of Tax-Exempt that corresponds to
the shares of Minnesota Series currently held by that Shareholder. Tax-Exempt
will cause its transfer agent to credit and confirm an appropriate number of
Tax-Exempt Shares to each Shareholder. Certificates for Tax-Exempt Shares will
be issued only upon written request of a Shareholder and only for whole shares,
with fractional shares credited to the name of the Shareholder on the books of
Tax-Exempt. Shareholders who wish to receive certificates representing their
Tax-Exempt Shares must, after receipt of their confirmations, make a written
request to Tax-Exempt's transfer agent Morgan Stanley Dean Witter Trust FSB,
Harborside Financial Center, Jersey City, New Jersey 07311. Shareholders of
Minnesota Series holding their shares in certificate form will be asked to
surrender such certificates in connection with the Reorganization. Shareholders
who do not surrender their certificates prior to the Closing Date will still
receive their shares of Tax-Exempt; however, such Shareholders will not be able
to redeem, transfer or exchange the Tax-Exempt Shares received until the old
certificates have been surrendered.

     The Closing Date will be the next business day following the Valuation
Date. The consummation of the Reorganization is contingent upon the approval of
the Reorganization by the Shareholders and the receipt of the other opinions
and certificates set forth in Sections 6, 7 and 8 of the Reorganization
Agreement and the occurrence of the events described in those Sections, certain
of which may be waived by Minnesota Series or Tax-Exempt. The Reorganization
Agreement may be amended in any mutually agreeable manner. All expenses of this
solicitation, including the cost of preparing and mailing this Proxy Statement
and Prospectus, will be borne by Minnesota Series, which expenses are expected
to approximate $60,000. Minnesota Series and Tax-Exempt will bear all of their
respective other expenses associated with the Reorganization.

     The Reorganization Agreement may be terminated and the Reorganization
abandoned at any time, before or after approval by Shareholders or by mutual
consent of Multi-State, on behalf of Minnesota Series, and Tax-Exempt. In
addition, either party may terminate the Reorganization Agreement upon the
occurrence of a material breach of the Reorganization Agreement by the other
party or if, by September 30, 2000, any condition set forth in the
Reorganization Agreement has not been fulfilled or waived by the party entitled
to its benefits.

     Under the Reorganization Agreement, within one year after the Closing
Date, Multi-State, on behalf of Minnesota Series, shall: either pay or make
provision for all of its liabilities and distribute any remaining amount of the
Cash Reserve (after paying or making provision for such liabilities and the
estimated cost of making the distribution) to former Shareholders of Minnesota
Series that received Tax-Exempt Shares. Minnesota Series shall be dissolved as
a portfolio of Multi-State under Massachusetts law promptly following the
distributions of shares of Tax-Exempt to Shareholders of record of Minnesota
Series.

     The effect of the Reorganization is that Shareholders who vote their
shares in favor of the Reorganization Agreement are electing to sell their
shares of Minnesota Series (at net asset value on the Valuation Date calculated
after subtracting any Cash Reserve) and reinvest the proceeds in Tax-Exempt
Shares at net asset value and without recognition of taxable gain or loss for
Federal income tax purposes. See "Tax Aspects of the Reorganization" below. As
noted in "Tax Aspects of the Reorganization" below, if Minnesota Series
recognizes net gain from the sale of securities prior to the Closing Date, such
gain, to the extent not offset by capital loss carryforwards, will be
distributed to Shareholders prior to the Closing Date and will be taxable to
Shareholders as capital gain.

     Shareholders will continue to be able to redeem their shares of Minnesota
Series at net asset value next determined after receipt of the redemption
request until the close of business on the business day next preceding the
Closing Date. Redemption requests received by Multi-State, on behalf of
Minnesota Series, thereafter will be treated as requests for redemption of
shares of Tax-Exempt.


                                       11

TAX ASPECTS OF THE REORGANIZATION

     At least one but not more than 20 business days prior to the Valuation
Date, Minnesota Series will declare and pay a dividend or dividends which,
together with all previous such dividends, will have the effect of distributing
to Shareholders all of Minnesota Series' investment company taxable income for
all periods since the inception of Minnesota Series through and including the
Valuation Date (computed without regard to any dividends paid deduction), and
all of Minnesota Series' net capital gain, if any, realized in such periods
(after reduction for any capital loss carryforward).

     The Reorganization is intended to qualify for Federal income tax purposes
as a tax-free reorganization under Section 368(a)(1)(C) of the Internal Revenue
Code of 1986, as amended (the "Code").

     As a condition to the Reorganization, Multi-State, on behalf of Minnesota
Series, and Tax-Exempt will receive an opinion of Mayer, Brown & Platt to the
effect that, based on certain assumptions, facts, the terms of the
Reorganization Agreement and representations set forth in the Reorganization
Agreement or otherwise provided by Multi-State, on behalf of Minnesota Series,
and Tax-Exempt (including a representation to the effect that Tax-Exempt has no
plan or intention to sell or otherwise dispose of more than fifty percent of
the assets of Minnesota Series acquired in the Reorganization except for
dispositions made in the ordinary course of business):

     1. The transfer of Minnesota Series' assets in exchange for the Tax-Exempt
Shares and the assumption by Tax-Exempt of certain stated liabilities of
Minnesota Series followed by the distribution by Minnesota Series of the
Tax-Exempt Shares to Shareholders in exchange for their Minnesota Series shares
pursuant to and in accordance with the terms of the Reorganization Agreement
will constitute a "reorganization" within the meaning of Section 368(a)(1)(C)
of the Code, and Minnesota Series and Tax-Exempt will each be a "party to a
reorganization" within the meaning of Section 368(b) of the Code;

     2. No gain or loss will be recognized by Tax-Exempt upon the receipt of
the assets of Minnesota Series solely in exchange for the Tax-Exempt Shares and
the assumption by Tax-Exempt of the stated liabilities of Minnesota Series;

     3. No gain or loss will be recognized by Minnesota Series upon the
transfer of the assets of Minnesota Series to Tax-Exempt in exchange for the
Tax-Exempt Shares and the assumption by Tax-Exempt of the stated liabilities or
upon the distribution of Tax-Exempt Shares to Shareholders in exchange for
their Minnesota Series shares;

     4. No gain or loss will be recognized by Shareholders upon the exchange of
the shares of Minnesota Series for the Tax-Exempt Shares;

     5. The aggregate tax basis for the Tax-Exempt Shares received by each of
the Shareholders pursuant to the Reorganization will be the same as the
aggregate tax basis of the shares in Minnesota Series held by each such
Shareholder immediately prior to the Reorganization;

     6. The holding period of the Tax-Exempt Shares to be received by each
Shareholder will include the period during which the shares in Minnesota Series
surrendered in exchange therefor were held (provided such shares in Minnesota
Series were held as capital assets on the date of the Reorganization);

     7. The tax basis of the assets of Minnesota Series acquired by Tax-Exempt
will be the same as the tax basis of such assets of Minnesota Series
immediately prior to the Reorganization; and

     8. The holding period of the assets of Minnesota Series in the hands of
Tax-Exempt will include the period during which those assets were held by
Minnesota Series.

     SHAREHOLDERS SHOULD CONSULT THEIR TAX ADVISORS REGARDING THE EFFECT, IF
ANY, OF THE PROPOSED TRANSACTION IN LIGHT OF THEIR INDIVIDUAL CIRCUMSTANCES.

DESCRIPTION OF SHARES

     Class D shares of Tax-Exempt to be issued pursuant to the Reorganization
Agreement will, when issued, be fully paid and non-assessable by Tax-Exempt and
transferable without restrictions and will have no preemptive rights. As stated
above, Class D shares of Tax-Exempt are not subject to any sales charge on
purchase or redemption or any 12b-1 fee.

APPRAISAL RIGHTS

        COMPARISON OF INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS


INVESTMENT OBJECTIVES AND POLICIES

     Minnesota Series and Tax-Exempt have partially similar investment
objectives. 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. Tax-Exempt seeks to provide a high level of current
income exempt from federal income tax consistent with preservation of capital.

     Both Minnesota Series and Tax-Exempt invest at least 80% of their
respective assets in securities that pay interest exempt from federal income
taxes, and with respect to Minnesota Series, Minnesota state income taxes, in
accordance with their respective investment objectives set forth above.
Tax-Exempt invests at least 75% of its assets in (i) municipal bonds rated
within the three highest grades by either Moody's Investors Service
("Moody's"), Standard & Poor's Corporation ("S&P") or Fitch IBCA, Inc.
("Fitch"); (ii) municipal notes rated within the two highest grades by Moody's,
S&P or Fitch, or, if not rated, have outstanding bonds within the


                                       13
<PAGE>

three highest grades by Moody's, S&P or Fitch; and (iii) municipal commercial
paper rated within the highest grade by such organizations. By contrast,
Minnesota Series may invest any amount of its assets in municipal bonds rated
within the four highest rating categories, and in municipal notes rated within
the two highest rating categories but, if unrated, they must have bonds
outstanding rated within the four highest categories. Like Tax-Exempt,
Minnesota Series may invest without limitation in municipal notes rated within
the highest rating category. In addition, Tax-Exempt is permitted to invest up
to 5% of its assets in municipal obligations rated below investment grade,
commonly known as "junk bonds," whereas, Minnesota Series may not invest in
municipal obligations rated below investment grade. Unrated securities may only
be purchased by either Minnesota Series or Tax-Exempt if such securities are
judged by the Investment Manager to be of comparable quality to the rated
securities described above.

     Both Minnesota Series and Tax-Exempt may invest up to 10% of their
respective 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 rates on the
obligations will increase and if market interest rates increase, the interest
rates on the obligations will fall.

     Both Minnesota Series and Tax-Exempt may invest up to 20% of their
respective assets in taxable money market instruments. Minnesota Series may
invest up to 20% of its assets in tax-exempt securities of other states and
municipalities. (Tax-Exempt may invest any amount of its assets in municipal
obligations of any state.)

     Minnesota Series may invest any amount of its assets in securities that
pay interest subject to the "alternative minimum tax" ("AMT") with the result
that some taxpayers may have to pay tax on income distributions from the
Minnesota Series. Tax-Exempt may only invest up to 20% of its assets in
securities subject to the AMT unless the fund has adopted a temporary defensive
posture as set forth below.

     Both Minnesota Series and Tax-Exempt may take temporary "defensive"
positions in attempting to respond to adverse market conditions. In doing so,
Minnesota Series may invest any amount of its assets in taxable money market
securities or, in the highest grade municipal obligations issued by states
other than Minnesota where interest on such obligations would normally be
exempt from federal income tax but not from Minnesota income tax. In addition,
during such a defensive posture, Tax-Exempt may also invest any amount of its
assets in taxable securities, or in tax-exempt securities subject to the AMT.

     Both Minnesota Series and Tax-Exempt may (i) purchase securities on a
when-issued or delayed delivery basis, (ii) purchase or sell securities on a
forward commitment basis, (iii) purchase variable and floating rate municipal
obligations, (iv) enter into repurchase agreements subject to certain
procedures designed to minimize risks associated with such agreements, (v)
purchase industrial revenue bonds, including lease obligations, and private
activity bonds, (vi) invest in zero coupon securities, (vii) lend their
portfolio securities and (viii) enter into options and futures transactions.
Additionally, Tax-Exempt may purchase securities on a when, as and if issued
basis.

     The foregoing discussion is a summary of the principal differences and
similarities between the investment policies of the funds. For a more complete
discussion of each fund's policies, see "Principal Investment Strategies" and
"Additional Investment Strategy Information" in Tax-Exempt's Prospectus and
"Principal Investment Strategy" and "Additional Investment Strategy
Information" in Multi-State's Prospectus; and "Description of the Fund and Its
Investments and Risks" in Tax-Exempt's Statement of Additional Information and
"Description of the Fund and the Investments and Risks of the Series" in
Multi-State's Statement of Additional Information.


INVESTMENT RESTRICTIONS

     The investment restrictions adopted by Minnesota Series and Tax-Exempt as
fundamental policies are substantially similar and are summarized under the
caption "Description of the Fund and Its Investments and Risks -- Fund
Policies/Investment Restrictions" in their respective Statements of Additional
Information. A


                                       14
<PAGE>

fundamental investment restriction cannot be changed without the vote of the
majority of the outstanding voting securities of a fund, as defined in the 1940
Act. The material differences are as follows: (a) Tax-Exempt may not invest
more than 5% of the value of its total assets in the securities of any one
issuer (other than U.S. Government securities); Minnesota Series, because it is
a non-diversified fund, has no such investment restriction but limits its
investments of 5% or more in the securities of any one issuer as to 50% of its
total assets in order to qualify as a regulated investment company under
Subchapter M of the Code; (b) Tax-Exempt may not purchase more than 10% of all
outstanding taxable debt securities of any one issuer (other than obligations
issued or guaranteed by the U.S. Government or its agencies or
instrumentalities; Minnesota Series has no such investment restriction; and (c)
Tax-Exempt may not invest more than 5% of the value of its total assets in
taxable securities of issuers (other than U.S. Government securities) that have
a record, together with predecessors, of less than three years of continuous
operation; Minnesota Series has no such investment restriction.

                     AGREEMENT AND PLAN OF REORGANIZATION

     THIS AGREEMENT AND PLAN OF REORGANIZATION ("Agreement") is made as of this
26th day of January, 2000, by and between MORGAN STANLEY DEAN WITTER TAX-EXEMPT
SECURITIES TRUST, a Massachusetts business trust ("Tax-Exempt") and MORGAN
STANLEY DEAN WITTER MULTI-STATE MUNICIPAL SERIES TRUST, a Massachusetts
business trust ("Multi-State"), on behalf of its series, MINNESOTA SERIES
("Minnesota Series"). (Where appropriate, references to Minnesota Series mean
Multi-State, on behalf of Minnesota Series.)

     This Agreement is intended to be and is adopted as a "plan of
reorganization" within the meaning of Treas. Reg. 1.368-2(g), for a
reorganization under Section 368(a)(1) of the Internal Revenue Code of 1986, as
amended (the "Code"). The reorganization ("Reorganization") will consist of the
transfer to Tax-Exempt of substantially all of the assets of Minnesota Series
in exchange for the assumption by Tax-Exempt of all stated liabilities of
Minnesota Series and the issuance by Tax-Exempt of Class D shares of beneficial
interest, par value $0.01 per share (the "Tax-Exempt Shares"), to be
distributed, after the Closing Date hereinafter referred to, to the
shareholders of Minnesota Series in liquidation of Minnesota Series as provided
herein, all upon the terms and conditions hereinafter set forth in this
Agreement.

     In consideration of the premises and of the covenants and agreements
hereinafter set forth, the parties hereto covenant and agree as follows:


1. THE REORGANIZATION AND LIQUIDATION OF MINNESOTA SERIES

     1.1 Subject to the terms and conditions herein set forth and on the basis
of the representations and warranties contained herein, Minnesota Series agrees
to assign, deliver and otherwise transfer the Minnesota Series Assets (as
defined in paragraph 1.2) to Tax-Exempt and Tax-Exempt agrees in exchange
therefor to assume all of Minnesota Series stated liabilities on the Closing
Date as set forth in paragraph 1.3(a) and to deliver to Minnesota Series the
number of Tax-Exempt Shares, including fractional Tax-Exempt Shares, determined
in the manner set forth in paragraph 2.3. Such transactions shall take place at
the closing provided for in paragraph 3.1 ("Closing").

     1.2 (a) The "Minnesota Series Assets" shall consist of all property,
including without limitation, all cash (other than the "Cash Reserve" (as
defined in paragraph 1.3(b)), cash equivalents, securities and dividend and
interest receivables owned by Minnesota Series, and any deferred or prepaid
expenses shown as an asset on Minnesota Series' books on the Valuation Date.

     (b) On or prior to the Valuation Date, Multi-State will provide Tax-Exempt
with a list of all of Minnesota Series assets to be assigned, delivered and
otherwise transferred to Tax-Exempt and of the stated liabilities to be assumed
by Tax-Exempt pursuant to this Agreement. Minnesota Series reserves the right
to sell any of the securities on such list but will not, without the prior
approval of Tax-Exempt, acquire any additional securities other than securities
of the type in which Tax-Exempt is permitted to invest and in amounts agreed to
in writing by Tax-Exempt. Tax-Exempt will, within a reasonable time prior to
the Valuation Date, furnish Minnesota Series with a statement of Tax-Exempt's
investment objectives, policies and restrictions and a list of the securities,
if any, on the list referred to in the first sentence of this paragraph that do
not conform to Tax-Exempt's investment objective, policies and restrictions. In
the event that Minnesota Series holds any investments that Tax-Exempt is not
permitted to hold, Minnesota Series will dispose of such securities on or prior
to the Valuation Date. In addition, if it is determined that the portfolios of
Minnesota Series and Tax-Exempt, when aggregated, would contain investments
exceeding certain percentage limitations imposed


                                      A-1
<PAGE>

upon Tax-Exempt with respect to such investments, Minnesota Series if requested
by Tax-Exempt will, on or prior to the Valuation Date, dispose of and/or
reinvest a sufficient amount of such investments as may be necessary to avoid
violating such limitations as of the Closing Date (as defined in paragraph
3.1).

     1.3 (a) Minnesota Series will endeavor to discharge all of its liabilities
and obligations on or prior to the Valuation Date. Tax-Exempt will assume all
stated liabilities, which includes, without limitation, all expenses, costs,
charges and reserves reflected on an unaudited Statement of Assets and
Liabilities of Minnesota Series prepared by the Treasurer of Multi-State, on
behalf of Minnesota Series, as of the Valuation Date in accordance with
generally accepted accounting principles consistently applied from the prior
audited period.

     (b) On the Valuation Date, Minnesota Series may establish a cash reserve,
which shall not exceed 5% of Minnesota Series' net assets as of the close of
business on the Valuation Date ("Cash Reserve") to be retained by Minnesota
Series and used for the payment of its liabilities not discharged prior to the
Valuation Date and for the expenses of dissolution.

     1.4 In order for Minnesota Series to comply with Section 852(a)(1) of the
Code and to avoid having any investment company taxable income or net capital
gain (as defined in Sections 852(b)(2) and 1222(11) of the Code, respectively)
in the short taxable year ending with its dissolution, Minnesota Series will on
or before the Valuation Date (a) declare a dividend in an amount large enough
so that it will have declared dividends of all of its investment company
taxable income and net capital gain, if any, for such taxable year (determined
without regard to any deduction for dividends paid) and (b) distribute such
dividend.

     1.5 On the Closing Date or as soon as practicable thereafter, Minnesota
Series will distribute Tax-Exempt Shares received by Minnesota Series pursuant
to paragraph 1.1 pro rata to its shareholders of record determined as of the
close of business on the Valuation Date ("Minnesota Series Shareholders"). Each
Minnesota Series Shareholder will receive Class D shares of Tax-Exempt. Such
distribution will be accomplished by an instruction, signed by the Secretary of
Multi-State, to transfer Tax-Exempt Shares then credited to Minnesota Series'
account on the books of Tax-Exempt to open accounts on the books of Tax-Exempt
in the names of the Minnesota Series Shareholders and representing the
respective pro rata number of Tax-Exempt Shares due such Minnesota Series
Shareholders. All issued and outstanding shares of Minnesota Series
simultaneously will be canceled on Minnesota Series' books; however, share
certificates representing interests in Minnesota Series will represent a number
of Tax-Exempt Shares after the Closing Date as determined in accordance with
paragraph 2.3. Tax-Exempt will issue certificates representing Tax-Exempt
Shares in connection with such exchange only upon the written request of a
Minnesota Series Shareholder.

     1.6 Ownership of Tax-Exempt Shares will be shown on the books of
Tax-Exempt's transfer agent. Tax-Exempt Shares will be issued in the manner
described in Tax-Exempt's current Prospectus and Statement of Additional
Information.

     1.7 Any transfer taxes payable upon issuance of Tax-Exempt Shares in a
name other than the registered holder of Tax-Exempt Shares on Minnesota Series'
books as of the close of business on the Valuation Date shall, as a condition
of such issuance and transfer, be paid by the person to whom Tax-Exempt Shares
are to be issued and transferred.

     1.8 Any reporting responsibility of Multi-State, on behalf of Minnesota
Series, is and shall remain the responsibility of Multi-State up to and
including the date on which Minnesota Series is dissolved pursuant to paragraph
1.9.

     1.9 Within one year after the Closing Date, Minnesota Series shall pay or
make provision for the payment of all its liabilities and taxes, and distribute
to the shareholders of Minnesota Series as of the close of business on the
Valuation Date any remaining amount of the Cash Reserve (as reduced by the
estimated cost of


                                      A-2
<PAGE>

distributing it to shareholders). If and to the extent that any trust, escrow
account, or other similar entity continues after the close of such one-year
period in connection either with making provision for payment of liabilities or
taxes or with distributions to shareholders of Minnesota Series, such entity
shall either (i) qualify as a liquidating trust under Section 7701 of the Code
(and applicable Treasury Regulations thereunder) or other entity which does not
constitute a continuation of Minnesota Series for federal income tax purposes,
or (ii) be subject to a waiver under Section 368(a)(2)(G)(ii) of the complete
distribution requirement of Section 368(a)(2)(G)(i) of the Code. Minnesota
Series shall be dissolved as a portfolio of Multi-State under Minnesota law,
promptly following the making of all distributions pursuant to paragraph 1.5
(and, in any event, within one year after the Closing Date).

     1.10 Copies of all books and records maintained on behalf of Minnesota
Series in connection with its obligations under the Investment Company Act of
1940, as amended (the "1940 Act"), the Code, state blue sky laws or otherwise
in connection with this Agreement will promptly after the Closing be delivered
to officers of Tax-Exempt or their designee and Tax-Exempt or its designee
shall comply with applicable record retention requirements to which Minnesota
Series is subject under the 1940 Act.


2. VALUATION

     2.1 The value of the Minnesota Series Assets shall be the value of such
assets computed as of 4:00 p.m. on the New York Stock Exchange on the third
business day following the receipt of the requisite approval by shareholders of
Minnesota Series of this Agreement or at such time on such earlier or later
date after such approval as may be mutually agreed upon in writing (such time
and date being hereinafter called the "Valuation Date"), using the valuation
procedures set forth in Tax-Exempt's then current Prospectus and Statement of
Additional Information.

     2.2 The net asset value of a Tax-Exempt Share shall be the net asset value
per share computed on the Valuation Date, using the valuation procedures set
forth in Tax-Exempt's then current Prospectus and Statement of Additional
Information.

     2.3 The number of Tax-Exempt Shares (including fractional shares, if any)
to be issued hereunder shall be determined, with respect to each class, by
dividing the aggregate net asset value of each class of Minnesota Series shares
(determined in accordance with paragraph 2.1) by the net asset value per share
of Class D shares of Tax-Exempt (determined in accordance with paragraph 2.2).
For purposes of this paragraph, the aggregate net asset value of the shares of
Minnesota Series shall not include the amount of the Cash Reserve.

     2.4 All computations of value shall be made by Morgan Stanley Dean Witter
Services Company Inc. ("MSDW Services") in accordance with its regular practice
in pricing Tax-Exempt. Tax-Exempt shall cause MSDW Services to deliver a copy
of its valuation report at the Closing.


3. CLOSING AND CLOSING DATE

     3.1 The Closing shall take place on the next business day following the
Valuation Date (the "Closing Date"). The Closing shall be held as of 9:00 a.m.
Eastern time, or at such other time as the parties may agree. The Closing shall
be held in a location mutually agreeable to the parties hereto. All acts taking
place at the Closing shall be deemed to take place simultaneously as of 9:00
a.m. Eastern time on the Closing Date unless otherwise provided.

     3.2 Portfolio securities held by Minnesota Series and represented by a
certificate or other written instrument shall be presented by it or on its
behalf to The Bank of New York (the "Custodian"), as custodian for Tax-Exempt,
for examination no later than five business days preceding the Valuation Date.
Such portfolio


                                      A-3
<PAGE>

securities (together with any cash or other assets) shall be delivered by
Minnesota Series to the Custodian for the account of Tax-Exempt on or before
the Closing Date in conformity with applicable custody provisions under the
1940 Act and duly endorsed in proper form for transfer in such condition as to
constitute good delivery thereof in accordance with the custom of brokers. The
portfolio securities shall be accompanied by all necessary Federal and state
stock transfer stamps or a check for the appropriate purchase price of such
stamps. Portfolio securities and instruments deposited with a securities
depository (as defined in Rule 17f-4 under the 1940 Act) shall be delivered on
or before the Closing Date by book-entry in accordance with customary practices
of such depository and the Custodian. The cash delivered shall be in the form
of a Federal Funds wire, payable to the order of "The Bank of New York,
Custodian for Morgan Stanley Dean Witter Tax-Exempt Securities Trust."

     3.3 In the event that on the Valuation Date, (a) the New York Stock
Exchange shall be closed to trading or trading thereon shall be restricted or
(b) trading or the reporting of trading on such Exchange or elsewhere shall be
disrupted so that, in the judgment of both Tax-Exempt and Minnesota Series,
accurate appraisal of the value of the net assets of Tax-Exempt or the
Minnesota Series Assets is impracticable, the Valuation Date shall be postponed
until the first business day after the day when trading shall have been fully
resumed without restriction or disruption and reporting shall have been
restored.

     3.4 If requested, Multi-State shall deliver to Tax-Exempt or its designee
(a) at the Closing, a list, certified by its Secretary, of the names, addresses
and taxpayer identification numbers of the Minnesota Series Shareholders and
the number and percentage ownership of outstanding Minnesota Series shares
owned by each such Minnesota Series Shareholder, all as of the Valuation Date,
and (b) as soon as practicable after the Closing, all original documentation
(including Internal Revenue Service forms, certificates, certifications and
correspondence) relating to the Minnesota Series Shareholders' taxpayer
identification numbers and their liability for or exemption from back-up
withholding. Tax-Exempt shall issue and deliver to such Secretary a
confirmation evidencing delivery of Tax-Exempt Shares to be credited on the
Closing Date to Minnesota Series or provide evidence satisfactory to Minnesota
Series that such Tax-Exempt Shares have been credited to Minnesota Series'
account on the books of Tax-Exempt. At the Closing, each party shall deliver to
the other such bills of sale, checks, assignments, share certificates, if any,
receipts or other documents as such other party or its counsel may reasonably
request.

     (l) For each taxable year since its inception, Minnesota Series, has met
   all the requirements of Subchapter M of the Code for qualification and
   treatment as a "regulated investment company" and neither the execution or
   delivery of nor the performance of its obligations under this Agreement

   meet the requirements of Subchapter M of the Code;

   purchased by Minnesota Series which have not settled prior to the Closing
   Date), security interests or other encumbrances, and full right, power and
   authority to assign, deliver and otherwise transfer such assets hereunder,

   and marketable title thereto, subject to no restrictions on the full
   transfer thereof, including any restrictions as might arise under the 1933
   Act;

   the meeting of Minnesota Series' shareholders and on the Closing Date, the
   Proxy Materials (exclusive of the currently effective

   that may be necessary in connection with the transactions contemplated

   respects with applicable Federal securities and other laws and regulations
   thereunder;

     (o) Minnesota Series will, on or prior to the Valuation Date, declare one
   or more dividends or other distributions to shareholders that, together
   with all previous dividends and other distributions to shareholders, shall

   Date (computed without regard to any deduction for dividends paid);

     (p) Multi-State has maintained or has caused to be maintained on its
   behalf all books and accounts as required of a registered investment company
   in compliance with the requirements of Section 31 of the 1940 Act and the
   Rules thereunder; and

     (q) Minnesota Series is not acquiring Tax-Exempt Shares to be issued
   hereunder for the purpose of making any distribution thereof other than in
   accordance with the terms of this Agreement.

conditions:

     7.1 All representations and warranties of Multi-State contained in this

reflect, in all material respects, the Federal and state income tax liabilities

limited review (based on unaudited financial data) to ascertain the amount of
applicable Federal, state and local taxes and has determined that same either

them to believe that the taxes paid or reserves set aside for payment of such
taxes were not


                                      A-10
<PAGE>

adequate in all material respects for the satisfaction of all Federal, state

Mayer, Brown & Platt, counsel to Multi-State, dated as of the Closing Date to

   Registration Statement complies with the 1933 Act, the 1934 Act and the
   1940 Act and the regulations thereunder and assuming due authorization,
   execution and delivery of this Agreement by Tax-Exempt, is a valid and
   binding obligation of Multi-State enforceable against Multi-State in

   insolvency, reorganization, moratorium and other laws relating to or
   affecting creditors rights and to general equity principles; (d) the
   execution and delivery of this Agreement did not, and the consummation of
   the transactions contemplated hereby will not, violate Multi-State's
   Declaration of Trust or By-Laws (Massachusetts counsel may be relied upon
   in delivering such opinion); and (e) to the knowledge of such counsel, no
   consent, approval, authorization or order of any court or governmental
   authority of the United States or any state is required for the
   consummation by Multi-State of the transactions contemplated herein, except

Trust or otherwise, may not properly acquire.

Brown & Platt (based on such representations as such law firm shall reasonably

   Minnesota Series followed by the distribution by Minnesota Series of
   Tax-Exempt Shares to the Minnesota Series Shareholders in exchange for
   their Minnesota Series shares pursuant to and in accordance with the terms
   of the Reorganization Agreement will constitute a "reorganization" within

   Tax-Exempt will each be a "party to a reorganization" within the meaning of
   Section 368(b) of the Code;

   Tax-Exempt Shares;

     (e) The aggregate tax basis for Tax-Exempt Shares received by each
   Minnesota Series Shareholder pursuant to the reorganization will be the
   same as the aggregate tax basis of the Minnesota Series Shares held by each
   such Minnesota Series Shareholder immediately prior to the Reorganization;

     (f) The holding period of Tax-Exempt Shares to be received by each
   Minnesota Series Shareholder will include the period during which the
   Minnesota Series Shares surrendered in exchange therefor were held
   (provided such Minnesota Series Shares were held as capital assets on the
   date of the Reorganization);

     (g) The tax basis of the assets of Minnesota Series acquired by
   Tax-Exempt will be the same as the tax basis of such assets to Minnesota
   Series immediately prior to the Reorganization; and

     (h) The holding period of the assets of Minnesota Series in the hands of
   Tax-Exempt will include the period during which those assets were held by
   Minnesota Series.

     Notwithstanding anything herein to the contrary, neither Tax-Exempt nor

the following ratings at the time of purchase:


o  municipal bonds --                 within the three highest grades by
                                      Moody's Investors Service Inc.
                                      ("Moody's"), Standard & Poor's
                                      Corporation ("S&P"), or Fitch IBCA,
                                      Inc. ("Fitch");

o  municipal notes --                 within the two highest grades or, if
                                      not rated, have outstanding bonds
                                      within the three highest grades by
                                      Moody's, S&P or Fitch; and

o  municipal commercial paper --      within the highest grade by
                                      Moody's, S&P or Fitch.


The Fund may invest up to 25% of its assets in municipal obligations that are
rated below the limits stated above or are not rated by those rating agencies.
However, the Fund may only invest up to 5% of its assets in municipal
obligations rated below investment grade or, if unrated, of comparable quality
as determined by the Investment Manager (commonly known as "junk bonds").


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


The Fund may invest up to 20% of its assets in taxable money market instruments
or securities that pay interest income subject to the "alternative minimum tax,"
and some


                                                                               1

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.


Municipal bonds, notes and commercial paper are commonly classified as either
"general obligation" or "revenue." General obligation bonds, notes, and
commercial paper are secured by the issuer's faith and credit including its
taxing power, for payment of principal and interest. Revenue bonds, notes and
commercial paper, however, are generally payable from a specific source of
income. They are issued to fund a wide variety of public and private projects in
sectors such as transportation, education and industrial development. Included
within the revenue category are participations in lease obligations. The Fund's
municipal obligation investments may include zero coupon securities, which are
purchased at a discount and accrue interest, but make no interest payments until
maturity.


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.

PRINCIPAL RISKS
- ---------------

There is no assurance that the Fund will achieve its investment objective. The
Fund's share price and yield will fluctuate with changes in the market value of
the Fund's portfolio securities. When you sell Fund shares, they may be worth
less than what you paid for them and, accordingly, you can lose money investing
in this Fund.

Credit and Interest Rate Risks. 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 projects in sectors such
as industrial development and pollution control, also may be negatively impacted
by the general credit of the user of the project.

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. As a general illustration of the
relationship between fixed-income securities and interest rates, the following
table shows how interest rates affect bond prices.

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.


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 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.


                                                                               3

Other Risks. The performance of the Fund also will depend on whether the
Investment Manager is successful in pursuing the Fund's investment strategy. The
Fund is also subject to other risks from its permissible investments including
the risks associated with its lease obligations 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.

The bar chart reflects the performance of Class D shares. All shares held prior
to the Fund adopting its Multi-Class Structure on July 28, 1997 were designated
Class D Shares. Prior to that date, shares were subject to a front-end sales
charge, which is not reflected in the bar chart. The performance of the other
Classes will differ because the Classes have different ongoing fees.

During the periods shown in the bar chart, the highest return for a calendar
quarter was 6.89% (quarter ended March 31, 1995) and the lowest return for a
calendar quarter was -5.50% (quarter ended March 31, 1994).

1   Prior to July 28, 1997 the Fund offered only one class of shares. Because
    the distribution arrangement for Class A most closely resembled the
    distribution arrangement applicable prior to the implementation of multiple
    classes (i.e., Class A is sold with a front-end sales charge), historical
    performance information has been restated to reflect the actual maximum
    sales charge applicable to Class A (i.e., 4.25%) as compared to the 4.00%
    sales charge in effect prior to July 28, 1997. In addition, Class A shares
    are now subject to an ongoing 12b-1 fee which is reflected in the restated
    performance for that class.
2   Classes B and C commenced operations on July 28, 1997.
3   Because all shares of the Fund held prior to July 28, 1997 were designated
    Class D shares, the Fund's historical performance has been restated to
    reflect the absence of any sales charge.
4   The Lehman Brothers Municipal Bond Index tracks the performance of Municipal
    bonds with maturities of 2 years or more and a minimum credit rating of Baa
    or BBB, as measured by Moody's Investor Service, Inc. or Standard & Poor's
    Corp. The Index does not include any expenses, fees, or changes. The Index
    is unmanaged and should not be considered an investment.

EXAMPLE

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


The example assumes that you invest $10,000 in the Fund, your investment has a
5% return each year, and the Fund's operating expenses remain the same. Although
your actual costs may be higher or lower, the tables below show your costs at
the end of each period based on these assumptions depending upon whether or not
you sell (redeem) your shares at the end of each period.

Long-term shareholders of Class B and Class C may pay more in sales charges,
including distribution fees, than the economic equivalent of the maximum
front-end sales charges permitted by the NASD.

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

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

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.


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 securities, or in tax-exempt securities subject
to the federal alternative minimum tax for individual shareholders when the
Investment Manager believes it is advisable to do so. Although taking a
defensive posture is designed to protect the Fund from an anticipated market
downturn, it could have the effect of reducing the Fund's ability to provide
tax-exempt income. When the Fund takes a defensive position, it may not achieve
its investment objective.


The percentage limitations relating to the composition of the Fund's portfolio
apply at the time the Fund acquires an investment and refer to the Fund's net
assets, unless otherwise noted. Subsequent percentage changes that result from
market fluctuations


                                                                               7

will not require the Fund to sell any portfolio security. The Fund may change
its principal investment strategies without shareholder approval; however, you
would be notified of any changes.




[GRAPHIC OMITTED]


ADDITIONAL RISK INFORMATION
- ---------------------------

This section provides additional information relating to the principal risks of
investing in the Fund.


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.


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, in part, 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.

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, NY 10048.


The Fund's portfolio is managed within the Investment Manager's Tax-Exempt
Group. James F. Willison, Senior Vice President and Director of the Tax-Exempt
Fixed-Income Group of the Investment Manager has been a primary portfolio
manager of the Fund since its inception. Joseph R. Arcieri, Senior Vice
President of the Investment Manager, has been a primary portfolio manager of the
Fund since February 1997. Mr. Willison and Mr. Arcieri have been portfolio
managers 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 December 31, 1999, the Fund
accrued total compensation to the Investment Manager amounting to 0.44% of the
Fund's average daily net assets.


                                                                               9

SHAREHOLDER INFORMATION

PRICING FUND SHARES
- -------------------

The price of Fund shares (excluding sales charges), called "net asset value," is
based on the value of the Fund's portfolio securities. While the assets of each
Class are invested in a single portfolio of securities, the net asset value of
each Class will differ because the Classes have different ongoing distribution
fees.

The net asset value per share of the Fund is determined once daily at 4:00 p.m.
Eastern time on each day that the New York Stock Exchange is open (or, on days
when the New York Stock Exchange closes prior to 4:00 p.m., at such earlier
time). Shares will not be priced on days that the New York Stock Exchange is
closed.

The 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.

An exception to the Fund's general pricing policy concerns its short-term debt
securities. Debt securities with remaining maturities of sixty days or less at
the time of purchase are valued at amortized cost. However, if the cost does not
reflect the securities' market value, these securities will be valued at their
fair value.

Because every investor has different immediate financial needs and long-term
investment goals, the Fund offers investors four Classes of shares: Classes A,
B, C and D. Class D shares are only offered to a limited group of investors.
Each Class of shares offers a distinct structure of sales charges, distribution

HOW TO EXCHANGE SHARES
- ----------------------

Permissible Fund Exchanges. You may exchange shares of any Class of the Fund for
the same Class of any other continuously offered Multi-Class Fund, or for shares
of a No-Load Fund, a Money Market Fund, North American Government Income Trust
or Short-Term U.S. Treasury Trust, without the imposition of an exchange fee.
See the inside back cover of this prospectus for each Morgan Stanley Dean Witter
Fund's designation as a Multi-Class Fund, No-Load Fund or Money Market Fund. If
a Morgan Stanley Dean Witter Fund is not listed, consult the inside back cover
of that Fund's prospectus for its designation. For purposes of exchanges, shares
of FSC Funds (subject to a front-end sales charge) are treated as Class A shares
of a Multi-Class Fund.


Exchanges may be made after shares of the Fund acquired by purchase have been
held for thirty days. There is no waiting period for exchanges of shares
acquired by exchange or dividend reinvestment. The current prospectus for each
fund describes its investment objective(s), policies and investment minimums,
and should be read before investment. Since exchanges are available only into
continuously offered Morgan Stanley Dean Witter Funds, exchanges are not
available into any new Morgan Stanley Dean Witter Fund during its initial
offering period, or when shares of a particular Morgan Stanley Dean Witter Fund
are not being offered for purchase.


Exchange Procedures. You can process an exchange by contacting your Morgan
Stanley Dean Witter Financial Advisor or other authorized financial
representative. Otherwise, you must forward an exchange privilege authorization
form to the Fund's transfer agent -- Morgan Stanley Dean Witter Trust FSB -- and
then write the transfer agent or call (800) 869-NEWS to place an exchange order.
You can obtain an exchange privilege authorization form by contacting your
Financial Advisor or other authorized financial representative, or by calling
(800) 869-NEWS. If you hold share certificates, no exchanges may be processed
until we have received all applicable share certificates.


An exchange to any Morgan Stanley Dean Witter Fund (except a Money Market Fund)
is made on the basis of the next calculated net asset values of the Funds
involved after the exchange instructions are accepted. When exchanging into a
Money Market Fund, the Fund's shares are sold at their next calculated net asset
value and the Money Market Fund's shares are purchased at their net asset value
on the following business day.


The Fund may terminate or revise the exchange privilege upon required notice.
The check writing privilege is not available for Money Market Fund shares you
acquire in an exchange.


Telephone Exchanges. For your protection when calling Morgan Stanley Dean Witter
Trust FSB, we will employ reasonable procedures to confirm that exchange
instructions communicated over the telephone are genuine. These procedures may
include


12

<PAGE>


requiring various forms of personal identification such as name, mailing
address, social security or other tax identification number. Telephone
instructions also may be recorded.


Telephone instructions will be accepted if received by the Fund's transfer agent
between 9:00 a.m. and 4:00 p.m. Eastern time on any day the New York Stock
Exchange is open for business. During periods of drastic economic or market
changes, it is possible that the telephone exchange procedures may be difficult
to implement, although this has not been the case with the Fund in the past.


Margin Accounts. If you have pledged your Fund shares in a margin account,
contact your Morgan 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.


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.



CDSC Calculations on Exchanges. See the "Share Class Arrangements" section of
this Prospectus for a further discussion of how applicable contingent deferred
sales charges (CDSCs) are calculated for shares of one Morgan Stanley Dean
Witter Fund that are exchanged for shares of another.


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


                                                                              13

HOW TO SELL SHARES
- ------------------

You can sell some or all of your Fund shares at any time. If you sell Class A,
Class B or Class C shares, your net sale proceeds are reduced by the amount of
any applicable CDSC. Your shares will be sold at the next price calculated after
we receive your order to sell as described below.

OPTIONS                PROCEDURES
Contact Your           To sell your shares, simply call your Morgan Stanley
Financial Advisor      Dean Witter Financial Advisor or other authorized
                       financial representative.

[GRAPHIC OMITTED]      Payment will be sent to the address to which the account
                       is registered or deposited in your brokerage account.

By Letter              You can also sell your shares by writing a
                       "letter of instruction" that includes:
                       o your account number;
                       o the dollar amount or the number
                         of shares you wish to sell;
                       o the Class of shares you wish to sell; and
[GRAPHIC OMITTED]      o the signature of each owner as it appears on the
                         account.

                       If you are requesting payment to anyone other than the
                       registered owner(s) or that payment be sent to any
                       address other than the address of the registered
                       owner(s) or pre-designated bank account, you will need a
                       signature guarantee. You can obtain a signature
                       guarantee from an eligible guarantor acceptable to
                       Morgan Stanley Dean Witter Trust FSB. (You should
                       contact Morgan Stanley Dean Witter Trust FSB at (800)
                       869-NEWS for a determination as to whether a particular
                       institution is an eligible guarantor.) A notary public
                       cannot provide a signature guarantee. Additional
                       documentation may be required for shares held by a
                       corporation, partnership, trustee or executor.

                       Mail the letter to Morgan Stanley Dean Witter Trust FSB
                       at P.O. Box 983, Jersey City, NJ 07303. If you hold
                       share certificates, you must return the certificates,
                       along with the letter and any required additional
                       documentation.

                       A check will be mailed to the name(s) and address in
                       which the account is registered, or otherwise according
                       to your instructions.

Systematic             If your investment in all of the Morgan Stanley Dean
Withdrawal Plan        Witter Family of Funds has a total Withdrawal Plan
[GRAPHIC OMITTED]      market value of at least $10,000, you may elect to
                       withdraw amounts of $25 or more, or in any whole
                       percentage of a Fund's balance (provided the amount is
                       at least $25), on a monthly, quarterly, semi-annual or
                       annual basis, from any Fund with a balance of at least
                       $1,000. Each time you add a Fund to the plan, you must
                       meet the plan requirements.

                       Amounts withdrawn are subject to any applicable CDSC. A
                       CDSC may be waived under certain circumstances. See the
                       Class B waiver categories listed in the "Share Class
                       Arrangements" section of this Prospectus.

                       To sign up for the Systematic Withdrawal Plan, contact
                       your Morgan Stanley Dean Witter Financial Advisor or
                       call (800) 869-NEWS. You may terminate or suspend your
                       plan at any time. Please remember that withdrawals from
                       the plan are sales of shares, not Fund "distributions,"
                       and ultimately may exhaust your account balance. The
                       Fund may terminate or revise the plan at any time.
                       --------------------------------------------------------

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 the same Class of Fund shares at
their net asset value and receive a pro rata credit for any CDSC paid in
connection with the sale.


Involuntary Sales. The Fund reserves the right, on sixty days' notice, to sell
the shares of any shareholder (other than shares held in an IRA or 403(b)
Custodial Account) whose shares, due to sales by the shareholder, have a value
below $100, or in the case of an account opened through EasyInvest(SM), if after
12 months the shareholder has invested less than $1,000 in the account.


However, before the Fund sells your shares in this manner, we will notify you
and allow you sixty days to make an additional investment in an amount that will
increase the value of your account to at least the required amount before the
sale is processed. No CDSC will be imposed on any involuntary sale.


Margin Accounts. If you have pledged your Fund shares in a margin account,
contact your Morgan Stanley Dean Witter Financial Advisor or other authorized
financial representative regarding restrictions on the sale of such shares.


                                                                              15

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

(sidebar)
TARGETED DIVIDENDS(SM)
You may select to have your Fund distributions automatically invested in other
Classes of Fund shares or Classes of another Morgan Stanley Dean Witter Fund
that you own. Contact your Morgan Stanley Dean Witter Financial Advisor for
further information about this service.
(end sidebar)

The Fund passes substantially all of its earnings from income and capital gains
along to its investors as "distributions." The Fund earns interest from
fixed-income investments. These amounts are passed along to Fund shareholders as
"income dividend distributions." The Fund realizes capital gains whenever it
sells securities for a higher price than it paid for them. These amounts may be
passed along as "capital gain distributions."


The Fund declares income dividends separately for each Class. Distributions paid
on Class A and Class D shares usually will be higher than for Class B and Class
C because distribution fees that Class B and Class C pay are higher. Normally,
income dividends are declared on each day the New York Stock Exchange is open
for business, and 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.


Distributions are reinvested automatically in additional shares of the same
Class and automatically credited to your account, unless you request in writing
that all distributions be paid in cash. If you elect the cash option, processing
of your dividend checks begins immediately following the monthly payment date,
and the Fund will mail a monthly dividend check to you normally during the first
seven days of the following month. No interest will accrue on uncashed checks.
If you wish to change how your distributions are paid, your request should be
received by the Fund's transfer agent, Morgan Stanley Dean Witter Trust FSB, at
least five business days prior to the record date of the distributions.


[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.


16

<PAGE>


Taxes on Distributions. Your income dividend distributions are normally exempt
from federal income taxes -- to the extent they are derived from municipal
obligations. 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.


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


If the Fund makes any capital gain distributions, those distributions will
normally be subject to federal income tax when they are paid, whether you take
them in cash or reinvest them in the Fund shares. 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.


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


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


                                                                              17

SHARE CLASS ARRANGEMENTS
- ------------------------

The Fund offers several Classes of shares having different distribution
arrangements designed to provide you with different purchase options according
to your investment needs. Your Morgan Stanley Dean Witter Financial Advisor or
other authorized financial representative can help you decide which Class may be
appropriate for you.


The general public is offered three Classes: Class A shares, Class B shares and
Class C shares, which differ principally in terms of sales charges and ongoing
expenses. A fourth Class, Class D shares, is offered only to a limited category
of investors. Shares that you acquire through reinvested distributions will not
be subject to any front-end sales charge or CDSC -- contingent deferred sales
charge. Sales personnel may receive different compensation for selling each
Class of shares. The sales charges applicable to each Class provide for the
distribution financing of shares of that Class.


The chart below compares the sales charge and maximum annual 12b-1 fee
applicable to each Class:

                                                                   MAXIMUM
CLASS     SALES CHARGE                                         ANNUAL 12B-1 FEE
  A       Maximum 4.25% initial sales charge reduced for
          purchases of $25,000 or more; shares sold
          without an initial sales charge are generally
          subject to a 1.0% CDSC during the first year               0.25%
  B       Maximum 5.0% CDSC during the first year
          decreasing to 0% after six years                           0.60%
  C       1.0% CDSC during the first year                            0.70%
  D       None                                                       None


CLASS A SHARES Class A shares are sold at net asset value plus an initial sales
charge of up to 4.25%. The initial sales charge is reduced for purchases of
$25,000 or more according to the schedule below. Investments of $1 million or
more are not subject to an initial sales charge, but are generally subject to a
contingent deferred sales charge, or CDSC, of 1.0% on sales made within one year
after the last day of the month of purchase. The CDSC will be assessed in the
same manner and with the same CDSC waivers as with Class B shares. Class A
shares are also subject to a distribution (12b-1) fee of up to 0.25% of the
average daily net assets of the Class.

<PAGE>


The offering price of Class A shares includes a sales charge (expressed as a
percentage of the offering price) on a single transaction as shown in the
following table:


(sidebar)
FRONT-END SALES CHARGE OR FSC
An initial sales charge you pay when purchasing Class A shares that is based on
a percentage of the offering price. The percentage declines based upon the
dollar value of Class A shares you purchase. We offer three ways to reduce your
Class A sales charges -- the Combined Purchase Privilege, Right of Accumulation
and Letter of Intent.

</TABLE>

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

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

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

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

o Tax-exempt organizations.

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


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


Right of Accumulation. You also may benefit from a reduction of sales charges if
the cumulative net asset value of Class A shares of the Fund purchased in a
single transaction, together with shares of other Funds you currently own which
were previously purchased at a price including a front-end sales charge
(including shares acquired through reinvestment of distributions), amounts to
$25,000 or more. Also, if you have a cumulative net asset value of all your
Class A and Class D shares equal to at least $5 million (or $25 million for
certain employee benefit plans), you are eligible to purchase Class D shares of
any Fund subject to the Fund's minimum initial investment requirement.


                                                                              19

<PAGE>


You must notify your Morgan Stanley Dean Witter Financial Advisor or other
authorized financial representative (or Morgan Stanley Dean Witter Trust FSB if
you purchase directly through the Fund), at the time a purchase order is placed,
that the purchase qualifies for the reduced charge under the Right of
Accumulation. Similar notification must be made in writing when an order is
placed by mail. The reduced sales charge will not be granted if: (i)
notification is not furnished at the time of the order; or (ii) a review of the
records of Dean Witter Reynolds or other authorized dealer of Fund shares or the
Fund's transfer agent does not confirm your represented holdings.



Letter of Intent. The schedule of reduced sales charges for larger purchases
also will be available to you if you enter into a written "letter of intent." A
letter of intent provides for the purchase of Class A shares of the Fund or
other Multi-Class Funds or shares of FSC Funds within a thirteen-month period.
The initial purchase under a letter of intent must be at least 5% of the stated
investment goal. To determine the applicable sales charge reduction, you may
also include: (1) the cost of shares of other Morgan Stanley Dean Witter Funds
which were previously purchased at a price including a front-end sales charge
during the 90-day period prior to the distributor receiving the letter of
intent, and (2) the cost of shares of other Funds you currently own acquired in
exchange for shares of Funds purchased during that period at a price including a
front-end sales charge. You can obtain a letter of intent by contacting your
Morgan Stanley Dean Witter Financial Advisor or other authorized financial
representative, or by calling (800) 869-NEWS. If you do not achieve the stated
investment goal within the thirteen-month period, you are required to pay the
difference between the sales charges otherwise applicable and sales charges
actually paid, which may be deducted from your investment.


Other Sales Charge Waivers. In addition to investments of $1 million or more,
your purchase of Class A shares is not subject to a front-end sales charge (or a
CDSC upon sale) if your account qualifies under one of the following categories:

CLASS B SHARES Class B shares are offered at net asset value with no initial
sales charge but are subject to a contingent deferred sales charge, or CDSC, as
set forth in the table below. For the purpose of calculating the CDSC, shares
are deemed to have been purchased on the last day of the month during which they
were purchased.

CONTINGENT DEFERRED SALES CHARGE OR CDSC
A fee you pay when you sell shares of certain Morgan Stanley Dean Witter Funds
purchased without an initial sales charge. This fee declines the longer you hold
your shares as set forth in the table.

First                                                5.0%
Second                                               4.0%
Third                                                3.0%
Fourth                                               2.0%
Fifth                                                2.0%
Sixth                                                1.0%
Seventh and thereafter                               None

Each time you place an order to sell or exchange shares, shares with no CDSC
will be sold or exchanged first, then shares with the lowest CDSC will be sold
or exchanged next. For any shares subject to a CDSC, the CDSC will be assessed
on an amount equal to the lesser of the current market value or the cost of the
shares being sold. A lower CDSC schedule applies in most cases to shares of the
Fund acquired in connection with the reorganization of Dean Witter National
Municipal Trust and the Fund on November 7, 1997.


CDSC Waivers. A CDSC, if otherwise applicable, will be waived in the case of:

o Sales of shares held at the time you die or become disabled (within the
  definition in Section 72(m)(7) of the Internal Revenue Code which relates to
  the ability to engage in gainful employment), if the shares are:
  (i) registered either in your name (not a trust) or in the names of you and
  your spouse as joint tenants with right of survivorship; or (ii) held in a
  qualified corporate or self-employed retirement plan, IRA or 403(b) Custodial
  Account, provided in either case that the sale is requested within one year of
  your death or initial determination of disability.

o Sales in connection with the following retirement plan "distributions:" (i)
  lump-sum or other distributions from a qualified corporate or self-employed
  retirement plan following retirement (or, in the case of a "key employee" of a
  "top


                                                                              21

heavy" plan, following attainment of age 59 1/2); (ii) distributions from an
IRA or 403(b) Custodial Account following attainment of age 59 1/2; or (iii) a
tax-free return of an excess IRA contribution (a "distribution" does not include
a direct transfer of IRA, 403(b) Custodial Account or retirement plan assets to
a successor custodian or trustee).

o  Sales of shares in connection with the Systematic Withdrawal Plan of up
   to 12% annually of the value of each Fund from which plan sales are
   made. The percentage is determined on the date you establish the
   Systematic Withdrawal Plan and based on the next calculated share price.
   You may have this CDSC waiver applied in amounts up to 1% per month, 3%
   per quarter, 6% semi-annually or 12% annually. Shares with no CDSC will
   be sold first, followed by those with the lowest CDSC. As such, the
   waiver benefit will be reduced by the amount of your shares that are not
   subject to a CDSC. If you suspend your participation in the plan, you
   may later resume plan payments without requiring a new determination of
   the account value for the 12% CDSC waiver.

o  Sales of shares if you simultaneously invest the proceeds in the
   Investment Manager's mutual fund asset allocation program, pursuant
   to which investors pay an asset-based fee. Any shares you acquire
   in connection with the Investment Manager's mutual fund asset
   allocation program are subject to all of the terms and conditions
   of that program, including termination fees, mandatory sale or
   transfer restrictions on termination.


All waivers will be granted only following the Fund's distributor receiving
confirmation of your entitlement. If you believe you are eligible for a CDSC
waiver, please contact your Financial Advisor or call (800) 869-NEWS.


Distribution Fee. Class B shares are also subject to an annual 12b-1 fee of
0.60% of the average daily net assets of Class B.


Conversion Feature. After ten (10) years, Class B shares will convert
automatically to Class A shares of the Fund with no initial sales charge. The
ten year period runs from the last day of the month in which the shares were
purchased, or in the case of Class B shares acquired through an exchange, from
the last day of the month in which the original Class B shares were purchased;
the shares will convert to Class A shares based on their relative net asset
values in the month following the ten year period. At the same time, an equal
proportion of Class B shares acquired through automatically reinvested
distributions will convert to Class A shares on the same basis. (Class B shares
held before May 1, 1997, however, will convert to Class A shares in May 2007.)


Currently, the Class B share conversion is not a taxable event; the conversion
feature may be cancelled if it is deemed a taxable event in the future by the
Internal Revenue Service.


22

<PAGE>


If you exchange your Class B shares for shares of a Money Market Fund, a No-Load
Fund, North American Government Income Trust or Short-Term U.S. Treasury Trust,
the holding period for conversion is frozen as of the last day of the month of
the exchange and resumes on the last day of the month you exchange back into
Class B shares.


Exchanging Shares Subject to a CDSC. There are special considerations when you
exchange Fund shares that are subject to a CDSC. When determining the length of
time you held the shares and the corresponding CDSC rate, any period (starting
at the end of the month) during which you held shares of a fund that does not
charge a CDSC will not be counted. Thus, in effect the "holding period" for
purposes of calculating the CDSC is frozen upon exchanging into a fund that does
not charge a CDSC.


For example, if you held Class B shares of the Fund for one year, exchanged to
Class B of another Morgan Stanley Dean Witter Multi-Class Fund for another year,
then sold your shares, a CDSC rate of 4% would be imposed on the shares based on
a two year holding period -- one year for each Fund. However, if you had
exchanged the shares of the Fund for a Money Market Fund (which does not charge
a CDSC) instead of the Multi-Class Fund, then sold your shares, a CDSC rate of
5% would be imposed on the shares based on a one year holding period. The one
year in the Money Market Fund would not be counted. Nevertheless, if shares
subject to a CDSC are exchanged for a Fund that does not charge a CDSC, you will
receive a credit when you sell the shares equal to the distribution (12b-1)
fees, if any, you paid on those shares while in that Fund up to the amount of
any applicable CDSC.


In addition, shares that are exchanged into or from a Morgan Stanley Dean Witter
Fund subject to a higher CDSC rate will be subject to the higher rate, even if
the shares are re-exchanged into a Fund with a lower CDSC rate.

CLASS C SHARES Class C shares are sold at net asset value with no initial sales
charge but are subject to a CDSC of 1.0% on sales made within one year after the
last day of the month of purchase. The CDSC will be assessed in the same manner
and with the same CDSC waivers as with Class B shares.

Distribution Fee. Class C shares are subject to an annual distribution (12b-1)
fee of up to 0.70% of the average daily net assets of that Class. The Class C
shares' distribution fee may cause that Class to have higher expenses and pay
lower dividends than Class A or Class D shares. Unlike Class B shares, Class C
shares have no conversion feature and, accordingly, an investor that purchases
Class C shares may be subject to distribution (12b-1) fees applicable to Class C
shares for an indefinite period.


                                                                              23

<PAGE>


CLASS D SHARES Class D shares are offered without any sales charge on purchases
or sales and without any distribution (12b-1) fee. Class D shares are offered
only to investors meeting an initial investment minimum of $5 million and the
following investor categories:

o Investors participating in the Investment Manager's mutual fund asset
  allocation program (subject to all of its terms and conditions, including
  termination fees, mandatory sale or transfer restrictions on termination)
  pursuant to which they pay an asset-based fee.

o Persons participating in a fee-based investment program (subject to all of its
  terms and conditions, including termination fees, mandatory sale or transfer
  restrictions on termination) approved by the Fund's distributor pursuant to
  which they pay an asset-based fee for investment advisory, administrative and/
  or brokerage services.

o Certain unit investment trusts sponsored by Dean Witter Reynolds.


o Certain other open-end investment companies whose shares are distributed by
  the Fund's distributor.

o Investors who were shareholders of the Dean Witter Retirement Series on
  September 11, 1998 for additional purchases for their former Dean Witter
  Retirement Series accounts.


Meeting Class D Eligibility Minimums. To meet the $5 million initial investment
to qualify to purchase Class D shares you may combine: (1) purchases in a single
transaction of Class D shares of the Fund and other Morgan Stanley Dean Witter
Multi-Class Funds and/or (2) previous purchases of Class A and Class D shares of
Multi-Class Funds and shares of FSC Funds you currently own, along with shares
of Morgan Stanley Dean Witter Funds you currently own that you acquired in
exchange for those shares.

NO SALES CHARGES FOR REINVESTED CASH DISTRIBUTIONS If you receive a cash payment
representing an income dividend or capital gain and you reinvest that amount in
the applicable Class of shares by returning the check within 30 days of the
payment date, the purchased shares would not be subject to an initial sales
charge or CDSC.

PLAN OF DISTRIBUTION (RULE 12B-1 FEES) The Fund has adopted a Plan of
Distribution in accordance with Rule 12b-1 under the Investment Company Act of
1940 with respect to the distribution of Class A, Class B and Class C shares.
The Plan allows the Fund to pay distribution fees for the sale and distribution
of these shares. It also allows the Fund to pay for services to shareholders of
Class A, Class B and Class C shares. Because these fees are paid out of the
Fund's assets on an ongoing basis, over time these fees will increase the cost
of your investment in these Classes and may cost you more than paying other
types of sales charges.

A MUTUAL FUND THAT SEEKS TO
PROVIDE A HIGH LEVEL OF CURRENT
INCOME EXEMPT FROM FEDERAL
INCOME TAX, CONSISTENT WITH
THE PRESERVATION OF CAPITAL


<PAGE>

MORGAN STANLEY DEAN WITTER TAX-EXEMPT SECURITIES TRUST   Two World Trade Center,
Letter to the Shareholders December 31, 1999            New York, New York 10048


DEAR SHAREHOLDER:

Interest rates rose steadily during 1999, making it the worst year for the
fixed-income markets since 1994. The benchmark 30-year Treasury bond began the
year yielding 5.1 percent amid fears of a global recession. However, the
economic problems in Asia, Europe and Latin America abated as the year
progressed. The U.S. economy, led by consumer demand, experienced robust
growth. As a result, the fixed-income markets anticipated that the Federal
Reserve Board would change monetary policy and remove the liquidity it had
provided during the 1998 international economic crises. Between June and
November, the Fed raised the federal funds rate a total of 75 basis points from
4.75 percent to 5.50 percent. At year-end, the yield on the 30-year Treasury
bond was nearly 6.50 percent. Subsequently, on February 2, 2000, the fed-funds
rate was raised an additional 25 basis points.


MUNICIPAL MARKET CONDITIONS

The long-term insured municipal index yield began 1999 near a record low of
5.05 percent. By the end of December, this index yield had increased almost a
full percentage point, to 5.97 percent. Because bond prices move inversely to
changes in interest rates, higher yields have caused bond prices to decline
significantly. The increase in the index yield during 1999 translated into a 13
percent price decline for a generic insured municipal bond with a 30-year
maturity.

The municipal market index outperformed U.S. Treasury bonds early last year but
later gave ground as interest rates continued to rise. The ratio of the 30-year
municipal yield to the Treasury bond yield is a measure of relative
performance. The yield ratio declined from 99 percent in January to 91 percent
in May 1999 and ended the year at 92 percent. A declining ratio means
municipals have outperformed Treasuries and a rising ratio indicates
underperformance by municipals. Over the past five years, the ratio has ranged
from a high of 99 percent to a low of 82 percent.


<PAGE>

MORGAN STANLEY DEAN WITTER TAX-EXEMPT SECURITIES TRUST
Letter to the Shareholders December 31, 1999, continued


Higher interest rates reduced municipal market underwriting in 1999. New-issue
volume declined 20 percent. Refunding activity, the most
interest-rate-sensitive component of supply, was down more than 50 percent.

PERFORMANCE

The performance of Morgan Stanley Dean Witter Tax-Exempt Securities Trust was
impacted by the higher interest-rate environment. For the 12-month period ended
December 31, 1999, the Fund's Class A and D shares returned -2.82 percent and
- -2.71 percent, respectively. For the same period, the Fund's Class B and C
shares returned -3.25 percent and -3.37 percent, respectively. (The performance
of the Fund's four share classes varies because of differing expenses. Total
return figures assume the

reinvestment of all distributions and do not reflect the deduction of any
applicable sales charges.) During the same period, the Lehman Brothers
Municipal Bond Index returned -2.06 percent. The accompanying chart compares
the Fund's performance to that of the Lehman index.


PORTFOLIO STRUCTURE

The Fund's net assets of $1.02 billion were diversified among 14 long-term
sectors and 106 credits. As interest rates have increased, the Fund's
short-term investment position, which had ranged from 1 - 3 percent in 1998,
was gradually increased to 7 - 9 percent. Refunded bonds represented 12 percent
of net assets. Refunded issues have been refinanced and are generally defensive
portfolio holdings. At the end of December, the portfolio's average maturity
was 15 years. Average duration, a measure of sensitivity to interest-rate
changes, was a relatively short 7.6 years. The accompanying charts provide
current information on the portfolio's credit quality, sector distribution and
geographic diversification. Optional call provisions by year and their
respective cost (book) yields are also charted.


LOOKING AHEAD

The Federal Reserve Board raised the fed-funds rate twice last summer and once
more in November. These actions confirmed its previously disclosed bias of
becoming less accommodative in the face of continued strong domestic economic
growth. It is anticipated that the central bank may raise short-term interest
rates further in 2000, again influencing long-term rates. However, we believe
municipal bonds continue to offer tax-conscious investors good long-term value
relative to Treasuries. We continue to stress credit quality and a conservative
portfolio management profile.

We appreciate your ongoing support of Morgan Stanley Dean Witter Tax-Exempt
Securities Trust and look forward to continuing to serve your investment needs.



Very truly yours,

Prior to July 28, 1997 the Fund offered only one class of shares. Because the
distribution arrangement for Class A most closely resembled the distribution
arrangement applicable prior to the implementation of multiple classes (i.e.,
Class A is sold with a front-end sales charge), historical performance
information has been restated to reflect the actual maximum sales charge
applicable to Class A (i.e., 4.25%) as compared to the 4.00% sales charge in
effect prior to July 28, 1997. In addition, Class A shares are now subject to
an ongoing 12b-1 fee which is reflected in the restated performance for that
class.

Because all shares of the fund held prior to July 28, 1997 were designated
Class D shares, the Fund's historical performance has been restated to reflect
the absence of any sales charge.

      municipal bonds with maturities of 2 years or more and a minimum credit
      rating of Baa or BBB, as measured by Moody's Investors Service, Inc. or
      Standard & Poor's Corp. The Index does not include any expenses, fees, or
      charges. The Index is unmanaged and should not be considered an
      investment.

      year of purchase.

MORGAN STANLEY DEAN WITTER TAX-EXEMPT SECURITIES TRUST
Notes to Financial Statements December 31, 1999


1. ORGANIZATION AND ACCOUNTING POLICIES

Morgan Stanley Dean Witter Tax-Exempt Securities Trust (the "Fund") is
registered under the Investment Company Act of 1940, as amended, as a
diversified, open-end management investment company. The Fund's investment
objective is to provide a high level of current income which is exempt from
federal income tax, consistent with the preservation of capital. The Fund was
incorporated in Maryland in 1979, commenced operations on March 27, 1980 and
reorganized as a Massachusetts business trust on April 30, 1987. On July 28,
1997, the Fund converted to a multiple class share structure.

The Fund offers Class A shares, Class B shares, Class C shares and Class D
shares. The four classes are substantially the same except that most Class A
shares are subject to a sales charge imposed at the time of purchase and some
Class A shares, and most Class B shares and Class C shares are subject to a
contingent deferred sales charge imposed on shares redeemed within one year,
six years and one year, respectively. Class D shares are not subject to a sales
charge. Additionally, Class A shares, Class B shares and Class C shares incur
distribution expenses.

The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts and disclosures. Actual results could differ
from those estimates.

The following is a summary of significant accounting policies:

A. VALUATION OF INVESTMENTS - Portfolio securities are valued for the Fund by
an outside independent pricing service approved by the Trustees. The pricing
service has informed the Fund that in valuing the Fund's portfolio securities,
it uses both a computerized matrix of tax-exempt securities and evaluations by
its staff, in each case based on information concerning market transactions and
quotations from dealers which reflect the bid side of the market each day. The
Fund's portfolio securities are thus valued by reference to a combination of
transactions and quotations for the same or other securities believed to be
comparable in quality, coupon, maturity, type of issue, call provisions,
trading characteristics and other features deemed to be relevant. Short-term
debt securities having a maturity date of more than sixty days at time of
purchase are valued on a mark-to-market basis until sixty days prior to
maturity and thereafter at amortized cost based on their value on the 61st day.
Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.

B. ACCOUNTING FOR INVESTMENTS - Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
The Fund amortizes premiums and accretes discounts over the life of the
respective securities. Interest income is accrued daily.

MORGAN STANLEY DEAN WITTER TAX-EXEMPT SECURITIES TRUST
Notes to Financial Statements December 31, 1999, continued


C. MULTIPLE CLASS ALLOCATIONS - Investment income, expenses (other than
distribution fees), and realized and unrealized gains and losses are allocated
to each class of shares based upon the relative net asset value on the date
such items are recognized. Distribution fees are charged directly to the
respective class.

D. FEDERAL INCOME TAX STATUS - It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable and nontaxable income to its
shareholders. Accordingly, no federal income tax provision is required.

E. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS - The Fund records dividends and
distributions to its shareholders on the record date. The amount of dividends
and distributions from net investment income and net realized capital gains are
determined in accordance with federal income tax regulations which may differ
from generally accepted accounting principles. These "book/tax" differences are
either considered temporary or permanent in nature. To the extent these
differences are permanent in nature, such amounts are reclassified within the
capital accounts based on their federal tax-basis treatment; temporary
differences do not require reclassification. Dividends and distributions which
exceed net investment income and net realized capital gains for financial
reporting purposes but not for tax purposes are reported as dividends in excess
of net investment income or distributions in excess of net realized capital
gains. To the extent they exceed net investment income and net realized capital
gains for tax purposes, they are reported as distributions of paid-in-capital.


2. INVESTMENT MANAGEMENT AGREEMENT

Pursuant to an Investment Management Agreement with Morgan Stanley Dean Witter
Advisors Inc. (the "Investment Manager"), the Fund pays the Investment Manager
a management fee, accrued daily and payable monthly, by applying the following
annual rates to the Fund's net assets determined as of the close of each
business day: 0.50% to the portion of daily net assets not exceeding $500
million; 0.425% to the portion of daily net assets exceeding $500 million but
not exceeding $750 million; 0.375% to the portion of daily net assets exceeding
$750 million but not exceeding $1 billion; 0.35% to the portion of daily net
assets exceeding $1 billion but not exceeding $1.25 billion; and 0.325% to the
portion of daily net assets exceeding $1.25 billion.

Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes, at its own expense, office space, facilities, equipment,
clerical, bookkeeping and certain legal services and pays the salaries of all
personnel, including officers of the Fund who are employees of the Investment
Manager. The Investment Manager also bears the cost of telephone services,
heat, light, power and other utilities provided to the Fund.

3. PLAN OF DISTRIBUTION

Shares of the Fund are distributed by Morgan Stanley Dean Witter Distributors
Inc. (the "Distributor"), an affiliate of the Investment Manager. The Fund has
adopted a Plan of Distribution (the "Plan"), pursuant to Rule 12b-1 under the
Act. The Plan provides that the Fund will pay the Distributor a fee which is
accrued daily and paid monthly at the following annual rates: (i) Class A - up
to 0.25% of the average daily net assets of Class A; (ii) Class B - 0.60% of
the average daily net assets of Class B; and (iii) Class C - up to 0.70% of the
average daily net assets of Class C. In the case of Class A shares, amounts
paid under the Plan are paid to the Distributor for services provided. In the
case of Class B and Class C shares, amounts paid under the Plan are paid to the
Distributor for (1) services provided and the expenses borne by it and others
in the distribution of the shares of these Classes, including the payment of
commissions for sales of these Classes and incentive compensation to, and
expenses of, Morgan Stanley Dean Witter Financial Advisors and others who
engage in or support distribution of the shares or who service shareholder
accounts, including overhead and telephone expenses; (2) printing and
distribution of prospectuses and reports used in connection with the offering
of these shares to other than current shareholders; and (3) preparation,
printing and distribution of sales literature and advertising materials. In
addition, the Distributor may utilize fees paid pursuant to the Plan, in the
case of Class B shares, to compensate Dean Witter Reynolds Inc. ("DWR"), an
affiliate of the Investment Manager and Distributor, and other selected
broker-dealers for their opportunity costs in advancing such amounts, which
compensation would be in the form of a carrying charge on any unreimbursed
expenses.

In the case of Class B shares, provided that the Plan continues in effect, any
cumulative expenses incurred by the Distributor but not yet recovered may be
recovered through the payment of future distribution fees from the Fund
pursuant to the Plan and contingent deferred sales charges paid by investors
upon redemption of Class B shares. Although there is no legal obligation for
the Fund to pay expenses incurred in excess of payments made to the Distributor
under the Plan and the proceeds of contingent deferred sales charges paid by
investors upon redemption of shares, if for any reason the Plan is terminated,
the Trustees will consider at that time the manner in which to treat such
expenses. The Distributor has advised the Fund that such excess amounts,
including carrying charges, totaled $4,717,309 at December 31, 1999.

In the case of Class A shares and Class C shares, expenses incurred pursuant to
the Plan in any calendar year in excess of 0.25% or 0.70% of the average daily
net assets of Class A or Class C, respectively, will not be reimbursed by the
Fund through payments in any subsequent year, except that expenses representing
a gross sales credit to Morgan Stanley Dean Witter Financial Advisors or other
selected

broker-dealer representatives may be reimbursed in the subsequent calendar
year. For the year ended December 31, 1999, the distribution fee was accrued
for Class A shares and Class C shares at the annual rate of 0.13% and 0.70%,
respectively.

The Distributor has informed the Fund that for the year ended December 31,
1999, it received contingent deferred sales charges from certain redemptions of
the Fund's Class B shares and Class C shares of $274,899 and $10,671,
respectively and received $107,818 in front-end sales charges from sales of the
Fund's Class A shares. The respective shareholders pay such charges which are
not an expense of the Fund.


4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES

The cost of purchases and proceeds from sales of portfolio securities,
excluding short-term investments, for the year ended December 31, 1999
aggregated $137,618,438 and $245,779,835, respectively.

Morgan Stanley Dean Witter Trust FSB, an affiliate of the Investment Manager
and Distributor, is the Fund's transfer agent. At December 31, 1999, the Fund
had transfer agent fees and expenses payable of approximately $13,800.

The Fund has an unfunded noncontributory defined benefit pension plan covering
all independent Trustees of the Fund who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on years of service and compensation during the last five years
of service. Aggregate pension costs for the year ended December 31, 1999
included in Trustees' fees and expenses in the Statement of Operations amounted
to $5,892. At December 31, 1999, the Fund had an accrued pension liability of
$52,664 which is included in accrued expenses in the Statement of Assets and
Liabilities.


5. FEDERAL INCOME TAX STATUS

At December 31, 1999, the Fund had a net capital loss carryover of
approximately $4,670,000 which will be available through December 31, 2007 to
offset future capital gains to the extent provided by regulations.

MORGAN STANLEY DEAN WITTER TAX-EXEMPT SECURITIES TRUST
Report of Independent Accountants


TO THE SHAREHOLDERS AND TRUSTEES
OF MORGAN STANLEY DEAN WITTER TAX-EXEMPT SECURITIES TRUST

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Morgan Stanley Dean Witter
Tax-Exempt Securities Trust (the "Fund") at December 31, 1999, the results of
its operations for the year then ended, the changes in its net assets for each
of the two years in the period then ended and the financial highlights for each
of the periods presented, in conformity with accounting principles generally
accepted in the United States. These financial statements and financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with auditing standards
generally accepted in the United States, which require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement
presentation. We believe that our audits, which included confirmation of
securities at December 31, 1999 by correspondence with the custodian, provide a
reasonable basis for the opinion expressed above.

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.

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


[GRAPHIC OMITTED]

PRINCIPAL INVESTMENT STRATEGY
- -----------------------------


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.

<PAGE>

[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. 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.



10
<PAGE>

[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. 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.


                                                                              11

THE MASSACHUSETTS SERIES

[GRAPHIC OMITTED]

INVESTMENT OBJECTIVE
- --------------------

The Massachusetts Series seeks to provide a high level of current income exempt
from both federal and Massachusetts 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 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
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 Massachusetts Series' portfolio securities.

The Massachusetts 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 Massachusetts 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 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 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 Massachusetts income tax. Defensive investing could have
the effect of reducing the Massachusetts Series' ability to provide tax exempt
income or otherwise meet its investment objective.


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

PRINCIPAL RISKS
- ---------------

There is no assurance that the Massachusetts 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
Massachusetts 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 Massachusetts Series is subject to the added
credit risk of concentrating its investments in a single state -- Massachusetts
- -- and its municipalities. Because the Massachusetts Series concentrates its
investments in securities issued by Massachusetts state and local governments
and government authorities, the Massachusetts Series will be significantly
affected by the political, economic and regulatory developments concerning those
issuers. Should any difficulties develop concerning Massachusetts issuers
ability to pay principal and/or interest on their debt obligations, the Series'
value and yield could be adversely affected.

The Massachusetts 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 Massachusetts Series' portfolio securities, and the
Massachusetts Series' share price, to fall substantially. A table in the
"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
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 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 MICHIGAN SERIES

[GRAPHIC OMITTED]

INVESTMENT OBJECTIVE
- --------------------

The Michigan Series seeks to provide a high level of current income exempt from
both federal and Michigan 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 Michigan Series will invest at least 80% of its total assets in securities
that pay interest normally exempt from federal and Michigan state income taxes.
The Michigan Series' "Investment Manager," Morgan Stanley Dean Witter Advisors
Inc., generally invests in investment grade, Michigan 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 Michigan Series' portfolio
securities.

The Michigan 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 Michigan 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 Michigan Series distribution of this income.
The Michigan Series therefore may not be a suitable investment for these
investors. See the "Tax Consequences" section for more details.


The Michigan Series may take temporary "defensive" positions in attempting to
respond to adverse market conditions. The Michigan 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 Michigan income tax. Defensive investing could have the
effect of reducing the Michigan Series' ability to provide tax exempt income or
otherwise meet its investment objective.


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

[GRAPHIC OMITTED]

PRINCIPAL RISKS
- ---------------

There is no assurance that the Michigan 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 Michigan
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 Michigan Series is subject to the added
credit risk of concentrating its investments in a single state -- Michigan --
and its municipalities. Because the Michigan Series concentrates its investments
in securities issued by Michigan state and local governments and government
authorities, the Michigan Series will be significantly affected by the
political, economic and regulatory developments concerning those issuers. Should
any difficulties develop concerning Michigan issuers ability to pay principal
and/or interest on their debt obligations, the Series' value and yield could be
adversely affected.


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

The performance of the Michigan Series will depend on whether the Michigan
Series is successful in pursuing its investment strategy. The Michigan 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
Michigan 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 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.


22
<PAGE>

[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 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.

THE NEW JERSEY SERIES

INVESTMENT OBJECTIVE
- --------------------

from both federal and New Jersey state income taxes consistent with preservation
of capital.

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

(end sidebar)

The New Jersey Series will invest at least 80% of its total assets in securities
that pay interest normally exempt from federal and New Jersey state income
taxes. The New Jersey Series' "Investment Manager," Morgan Stanley Dean Witter
Advisors Inc., generally invests in investment grade, New Jersey 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 New Jersey

The New Jersey 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 New Jersey 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 New Jersey Series distribution of this
income. The New Jersey Series therefore may not be a suitable investment for
these investors. See the "Tax Consequences" section for more details.


The New Jersey Series may take temporary "defensive" positions in attempting to

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 New Jersey income tax. Defensive investing could have
the effect of reducing the New Jersey Series' ability to provide tax exempt
income or otherwise meet its investment objective.


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

[GRAPHIC OMITTED]

PRINCIPAL RISKS
- ---------------

There is no assurance that the New Jersey 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 New Jersey
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 New Jersey Series is subject to the added
credit risk of concentrating its investments in a single state -- New Jersey --
and its municipalities. Because the New Jersey Series concentrates its
investments in securities issued by New Jersey state and local governments and
government authorities, the New Jersey Series will be significantly affected by
the political, economic and regulatory developments concerning those issuers.
Should any difficulties develop concerning New Jersey issuers ability to pay
principal and/or interest on their debt obligations, the Series' value and yield
could be adversely affected.


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

The performance of the New Jersey Series will depend on whether the New Jersey
Series is successful in pursuing its investment strategy. The New Jersey 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 New Jersey Series' investments, see the "Additional Risk Information"
section.

THE NEW YORK SERIES

[GRAPHIC OMITTED]

INVESTMENT OBJECTIVE
- --------------------

The New York Series seeks to provide a high level of current income exempt from
both federal and New York 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 New York Series will invest at least 80% of its total assets in securities
that pay interest normally exempt from federal and New York state income taxes.
The New York Series' "Investment Manager," Morgan Stanley Dean Witter Advisors
Inc., generally invests in investment grade, New York 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 New York Series' portfolio
securities.

The New York 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 New York 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 New York Series distribution of this income.
The New York Series therefore may not be a suitable investment for these
investors. See the "Tax Consequences" section for more details.


The New York Series may take temporary "defensive" positions in attempting to
respond to adverse market conditions. The New York 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 New York income tax. Defensive investing could have the
effect of reducing the New York Series' ability to provide tax exempt income or
otherwise meet its investment objective.


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


30
<PAGE>

[GRAPHIC OMITTED]

PRINCIPAL RISKS
- ---------------

There is no assurance that the New York 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 New York
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 New York Series is subject to the added
credit risk of concentrating its investments in a single state -- New York --
and its municipalities. Because the New York Series concentrates its investments
in securities issued by New York state and local governments and government
authorities, the New York Series will be significantly affected by the
political, economic and regulatory developments concerning those issuers. Should
any difficulties develop concerning New York issuers ability to pay principal
and/or interest on their debt obligations, the Series' value and yield could be
adversely affected.


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

The performance of the New York Series will depend on whether the New York
Series is successful in pursuing its investment strategy. The New York 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 New
York 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 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

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

The Ohio Series may invest any amount of its assets in securities that pay

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 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'

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

[GRAPHIC OMITTED]

INVESTMENT OBJECTIVE
- --------------------

The Pennsylvania Series seeks to provide a high level of current income exempt
from both federal and Pennsylvania 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 Pennsylvania Series will invest at least 80% of its total assets in
securities that pay interest normally exempt from federal and Pennsylvania state
income taxes. The Pennsylvania Series' "Investment Manager," Morgan Stanley Dean
Witter Advisors Inc., generally invests in investment grade, Pennsylvania
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 Pennsylvania Series' portfolio securities.

The Pennsylvania 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 Pennsylvania 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 Pennsylvania Series distribution of this
income. The Pennsylvania Series therefore may not be a suitable investment for
these investors. See the "Tax Consequences" section for more details.


The Pennsylvania Series may take temporary "defensive" positions in attempting
to respond to adverse market conditions. The Pennsylvania 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 Pennsylvania income tax. Defensive investing could have
the effect of reducing the Pennsylvania Series' ability to provide tax exempt
income or otherwise meet its investment objective.


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

PRINCIPAL RISKS
- ---------------

There is no assurance that the Pennsylvania 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
Pennsylvania 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 Pennsylvania Series is subject to the added
credit risk of concentrating its investments in a single state -- Pennsylvania
- -- and its municipalities. Because the Pennsylvania Series concentrates its
investments in securities issued by Pennsylvania state and local governments and
government authorities, the Pennsylvania Series will be significantly affected
by the political, economic and regulatory developments concerning those issuers.
Should any difficulties develop concerning Pennsylvania issuers ability to pay
principal and/or interest on their debt obligations, the Series' value and yield
could be adversely affected.


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

The performance of the Pennsylvania Series will depend on whether the
Pennsylvania Series is successful in pursuing its investment strategy. The
Pennsylvania 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 Pennsylvania 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.


42
<PAGE>

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.


[GRAPHIC OMITTED]

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

                                                                              43
<PAGE>


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 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.

44
<PAGE>


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.


                                                                              45

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.

There is no minimum investment amount if you purchase Fund shares through: (1)
the Investment Manager's mutual fund asset allocation plan, (2) a program,
approved by the Fund's distributor, in which you pay an asset-based fee for
advisory, administrative and/or brokerage services, or (3) employer-sponsored
employee benefit plan accounts.


Advisory, Administrative or Brokerage Programs. There is no minimum investment
amount if you purchase Fund shares through: (1) the Investment Manager's mutual
fund asset allocation plan, or (2) a program, approved by the Series'
distributor, in which you pay an asset-based fee for advisory, administrative
and/or brokerage services.

Subsequent Investments Sent Directly to the Fund. In addition to buying
additional Series shares for an existing account by contacting your Morgan
Stanley Dean Witter Financial Advisor, you may send a check directly to a
Series. To buy additional shares in this manner:


o   Write a "letter of instruction" to the Series specifying the name(s) on the
    account, the account number, the social security or tax identification
    number, and the investment amount (which would include any applicable
    front-end sales charge). The letter must be signed by the account owner(s).

o   Make out a check for the total amount payable to: Morgan Stanley Dean Witter
    Multi-State Municipal Series Trust (name of Series).

o   Mail the letter and check to Morgan Stanley Dean Witter Trust FSB at P.O.
    Box 1040, Jersey City, NJ 07303.


Sales Charges. Shares of each Series are sold at net asset value plus an initial
sales charge of up to 4.0%. The initial sales charge is reduced for purchases of
$25,000 or more according to the schedule below. A Series' shares are also
subject to a distribution (12b-1) fee of up to 0.15% of the average daily net
assets of the Series.

                                                                              47

The offering price of Series shares includes a sales charge (expressed as a
percentage of the offering price) on a single transaction as shown in the
following table:

FRONT-END SALES CHARGE OR FSC
An initial sales charge you pay when purchasing a Series' shares that is based
on a percentage of the offering price. The percentage declines based upon the

your sales charges -- the Combined Purchase Privilege, Right of Accumulation and
Letter of Intent.

</TABLE>

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 sales charge will

48
<PAGE>

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.

                                                                              49

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 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

50
<PAGE>

requiring various forms of personal identification such as name, mailing
address, social security or other tax identification number. Telephone
instructions also may be recorded.


Telephone instructions will be accepted if received by the Fund's transfer agent
between 9:00 a.m. and 4:00 p.m. Eastern time on any day the New York Stock
Exchange is open for business. During periods of drastic economic or market
changes, it is possible that the telephone exchange procedures may be difficult
to implement, although this has not been the case with the Fund in the past.


Margin Accounts. If you have pledged your Fund shares in a margin account,
contact your Morgan 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 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.

Systematic            If your investment in all of the Morgan Stanley Dean Witter Family of Funds has a total
Withdrawal Plan       market value of at least $10,000, you may elect to withdraw amounts of $25 or more,
                      or in any whole percentage of a Fund's (or Series') balance (provided the amount is at
[GRAPHIC OMITTED]     least $25), on a monthly, quarterly, semi-annual or annual basis, from any Fund (or
                      Series) with a balance of at least $1,000. Each time you add a Fund to the plan, you must
                      meet the plan requirements.
                      ------------------------------------------------------------------------------------------
                      To sign up for the Systematic Withdrawal Plan, contact your Morgan Stanley Dean
                      Witter Financial Advisor or call (800) 869-NEWS. You may terminate or suspend your
                      plan at any time. Please remember that withdrawals from the plan are sales of shares,
                      not Fund "distributions," and ultimately may exhaust your account balance. The Fund
                      may terminate or revise the plan at any time.
- ----------------------------------------------------------------------------------------------------------------
By Letter             You can also sell your shares by writing a "letter of instruction" that includes:

[GRAPHIC OMITTED]     o  the dollar amount or the number of shares you wish to sell; and
                      o  the signature of each owner as it appears on the account.

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

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.

52
<PAGE>


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 EasyInvestSM, 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.


[GRAPHIC OMITTED]

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.

Distributions are reinvested automatically in additional shares of a Series and
automatically credited to your account, unless you request in writing that all

                                                                              53
<PAGE>

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'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.

54
<PAGE>

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.


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.

                                                                              55

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.

LETTER TO THE SHAREHOLDERS November 30, 1999
                                                         Two World Trade Center,
                                                        New York, New York 10048

DEAR SHAREHOLDER:

The U.S. economy, led by consumer demand, continued to experience robust growth
during the twelve-month period ended November 30, 1999. As a result, the
fixed-income markets anticipated that the Federal Reserve Board would change
monetary policy and remove the liquidity provided during last year's
international economic difficulties. Between June and November the Fed changed
monetary policy, raising the federal-funds rate 75 basis points in three moves,
to 5.50 percent. By November long-term interest rates had risen to levels last
seen more than two years ago.

MUNICIPAL MARKET OVERVIEW

Long-term insured municipal index yields began 1999 near a record low of 5.00
percent. By the end of November, this index yield had increased 100 basis
points to 6.00 percent. Because the prices of bonds move inversely to changes
in interest rates, higher yields have led to significantly lower bond prices.
The increase in the index yield translated to a 13 percent price decline for a
generic insured municipal bond with a 30-year maturity.

The municipal market outperformed U.S. Treasury bonds early in the year but
later gave ground. The ratio of municipal long-term yields to Treasury yields
declined from 99 percent at the end of 1998 to 91 percent in May 1999, then
reversed itself by rising to 95 percent by the end of November. A declining
ratio means municipals have outperformed Treasuries, and a rising ratio
indicates underperformance by municipals. Over the past five years the ratio
has ranged from a high of 99 percent to a low of 82 percent.

Higher interest rates slowed municipal underwriting in 1999. New-issue volume
declined 20 percent in the first 11 months. Refunding activity, the most
interest-rate-sensitive component of supply, dropped 50 percent.

PORTFOLIO STRUCTURE

The average duration of the 10 single-state portfolios that make up Morgan
Stanley Dean Witter Multi-State Municipal Series Trust was

<PAGE>

MORGAN STANLEY DEAN WITTER MULTI-STATE MUNICIPAL SERIES TRUST
LETTER TO THE SHAREHOLDERS November 30, 1999, continued


maintained at 7 years during the past 12 months. Average duration is a measure
of sensitivity to interest-rate changes. Weighted average bond maturities
ranged from 15 to 18 years and average call protection was 6 years. Several of
the individual state portfolios hold issues in the refunded-bond category.
These bonds have been refinanced and will be redeemed on the dates shown in the
individual state portfolios.

On the following pages we have summarized details regarding the various state
series for your convenience. Here you will find information on credit quality,
duration, maturity, call protection, net asset values, distributions and
performance. The accompanying charts compare the performance of each series to
that of the Lehman Brothers Municipal Bond Index.

LOOKING AHEAD

The Federal Reserve Board raised interest rates twice in the summer and again
in November 1999. These moves confirmed its previously disclosed bias of
becoming less accommodative in the face of continued strong domestic economic
growth. We anticipate that the central bank may raise short-term interest rates
further and influence the level of long-term rates. However, we believe
municipal bonds continue to offer tax conscious investors good long-term value
relative to Treasuries.

We appreciate your ongoing support of Morgan Stanley Dean Witter Multi-State
Municipal Series Trust and look forward to continuing to serve your investment
needs.

Very truly yours,

/s/ Charles A. Fiumefreddo                  /s/ Mitchell M. Merin

MORGAN STANLEY DEAN WITTER MULTI-STATE MUNICIPAL SERIES TRUST
NOTES TO FINANCIAL STATEMENTS November 30, 1999


1. ORGANIZATION AND ACCOUNTING POLICIES

Morgan Stanley Dean Witter Multi-State Municipal Series Trust (the "Fund") is
registered under the Investment Company Act of 1940, as amended (the "Act"), as
a non-diversified, open-end management investment company. The investment
objective of each Series is to provide a high level of current income exempt
from both Federal and the designated state income taxes consistent with
preservation of capital.

The Fund, organized on October 29, 1990, as a Massachusetts business trust, is
comprised of ten separate Series (the "Series"): the Arizona Series, the
California Series, the Florida Series, the Massachusetts Series, the Michigan
Series, the Minnesota Series, the New Jersey Series, the New York Series, the
Ohio Series and the Pennsylvania Series. Each of the Series commenced
operations on January 15, 1991, with the exception of the Arizona Series which
commenced operations on April 30, 1991.

The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts and disclosures. Actual results could differ
from those estimates.

The following is a summary of significant accounting policies:

A. VALUATION OF INVESTMENTS -- Portfolio securities are valued by an outside
independent pricing service approved by the Fund's Trustees. The pricing
service has informed the Fund that in valuing the portfolio securities, it uses
both a computerized matrix of tax-exempt securities and evaluations by its
staff, in each case based on information concerning market transactions and
quotations from dealers which reflect the bid side of the market each day. The
portfolio securities are thus valued by reference to a combination of
transactions and quotations for the same or other securities believed to be
comparable in quality, coupon, maturity, type of issue, call provisions,
trading characteristics and other features deemed to be relevant. Short-term
debt securities having a maturity date of more than sixty days at time of
purchase are valued on a mark-to-market basis until sixty days prior to
maturity and thereafter at amortized cost based on their value on the 61st day.
Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.

B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Discounts are accreted and premiums are amortized over the life of the
respective securities. Interest income is accrued daily.

NOTES TO FINANCIAL STATEMENTS November 30, 1999, continued


C. FEDERAL INCOME TAX STATUS -- It is the Fund's policy to comply individually
for each Series with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its taxable and
nontaxable income to its shareholders. Accordingly, no federal income tax
provision is required.

D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends
and distributions to its shareholders on the record date. The amount of
dividends and distributions from net investment income and net realized capital
gains are determined in accordance with federal income tax regulations which
may differ from generally accepted accounting principles. These "book/tax"
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the capital accounts based on their federal tax-basis treatment;
temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for financial reporting purposes but not for tax purposes are reported as
dividends in excess of net investment income or distributions in excess of net
realized capital gains. To the extent they exceed net investment income and net
realized capital gains for tax purposes, they are reported as distributions of
paid-in-capital.

E. EXPENSES -- Direct expenses are charged to the respective Series and general
corporate expenses are allocated on the basis of relative net assets or equally
among the Series.

2. INVESTMENT MANAGEMENT AGREEMENT

Pursuant to an Investment Management Agreement, each Series of the Fund pays
Morgan Stanley Dean Witter Advisors Inc. (the "Investment Manager") a
management fee, accrued daily and payable monthly, by applying the annual rate
of 0.35% to the daily net assets of each Series determined as of the close of
each business day.

Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes office space and facilities, equipment, clerical,
bookkeeping and certain legal services, and pays the salaries of all personnel,
including officers of the Fund who are employees of the Investment Manager. The
Investment Manager also bears the cost of telephone services, heat, light,
power and other utilities provided to the Fund.

3. PLAN OF DISTRIBUTION

Morgan Stanley Dean Witter Distributors Inc. (the "Distributor"), an affiliate
of the Investment Manager, is the distributor of the Fund's shares and, in
accordance with a Plan of Distribution (the "Plan") pursuant to Rule 12b-1
under the Act, finances certain expenses in connection with the distribution of
shares of the Fund.

Under the Plan, the expenses of certain activities and services provided by
Dean Witter Reynolds Inc. ("DWR"), an affiliate of the Investment Manager and
Distributor, and others who engage in or support distribution of the Fund's
shares or who service shareholder accounts, including overhead and telephone
expenses incurred in connection with the distribution of the Fund's shares, are
reimbursed.

Reimbursements for these expenses will be made in monthly payments by the Fund
to the Distributor, which will in no event exceed an amount equal to a payment
at the annual rate of 0.15% of the Fund's average daily net assets during the
month. Expenses incurred by the Distributor pursuant to the Plan in any fiscal
year will not be reimbursed by the Fund through payments accrued in any
subsequent fiscal year. For the year ended November 30, 1999, the distribution
fees were accrued at the following annual rates:

Michigan Series', the Minnesota Series' and the Ohio Series' shareholders,

dependent upon the approval of the other Plans) the assets of the Massachusetts

and shareholders of the California Series would become Class D shareholders of
California Tax-Free, receiving Class D shares of California Tax-Free equal to
the value of their holdings in the California Series.

New York Tax-Free Income Fund ("New York Tax-Free") approved a reorganization
plan (the "Plan") whereby the New York Series would be merged into New York

MORGAN STANLEY DEAN WITTER MULTI-STATE MUNICIPAL SERIES TRUST
REPORT OF INDEPENDENT ACCOUNTANTS


TO THE SHAREHOLDERS AND TRUSTEES
OF MORGAN STANLEY DEAN WITTER MULTI-STATE MUNICIPAL SERIES TRUST

In our opinion, the accompanying statements of assets and liabilities,
including the portfolios of investments, and the related statements of
operations and of changes in net assets and the financial highlights present
fairly, in all material respects, the financial position of the Arizona Series,
the California Series, the Florida Series, the Massachusetts Series, the
Michigan Series, the Minnesota Series, the New Jersey Series, the New York
Series, the Ohio Series, and the Pennsylvania Series (constituting the Morgan
Stanley Dean Witter Multi-State Municipal Series Trust, hereafter referred to
as the "Fund") at November 30, 1999, the results of each of their operations
for the year then ended, the changes in each of their net assets for each of
the two years in the period then ended and the financial highlights for each of
the five years in the period then ended, in conformity with generally accepted
accounting principles. These financial statements and financial highlights
(hereafter referred to as "financial statements") are the responsibility of the
Fund's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
financial statements in accordance with generally accepted auditing standards
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at November 30, 1999 by correspondence with the
custodian and brokers, provide a reasonable basis for the opinion expressed
above.

As described in Note 6 to the financial statements, the Fund's Trustees have
approved reorganization plans whereby the Massachusetts Series, the Michigan
Series, the Minnesota Series and the Ohio Series would each be merged into
Morgan Stanley Dean Witter Tax-Exempt Securities Trust, the California Series
would be merged into Morgan Stanley Dean Witter California Tax-Free Income Fund
and the New York Series would be merged into Morgan Stanley Dean Witter New
York Tax-Free Income Fund. Each respective Plan is subject to the consent of
the respective Series' shareholders.

     I. FUND HISTORY
- --------------------------------------------------------------------------------

     The Fund was incorporated in the State of Maryland on December 31, 1979
under the name InterCapital Tax-Exempt Securities Inc. On March 17, 1983, the
Fund's shareholders approved a change in the Fund's name, effective March 21,
1983, to Dean Witter Tax-Exempt Securities Inc. On April 30, 1987, the Fund
reorganized as a Massachusetts business trust, with the name Dean Witter
Tax-Exempt Securities Trust. Effective June 22, 1998, the Fund's name was
changed to Morgan Stanley Dean Witter Tax-Exempt Securities Trust.


II. DESCRIPTION OF THE FUND AND ITS INVESTMENTS AND RISKS
- --------------------------------------------------------------------------------

A. CLASSIFICATION


     The Fund is an open-end, diversified management investment company whose
investment objective is to provide a high level of current income exempt from
federal income tax, consistent with the preservation of capital.


B. INVESTMENT STRATEGIES AND RISKS

     The following discussion of the Fund's investment strategies and risks
should be read with the sections of the Fund's Prospectus titled "Principal
Investment Strategies," "Principal Risks," "Additional Investment Strategy
Information," and "Additional Risk Information."

     TAXABLE SECURITIES. The Fund may invest up to 20% of its total assets, or
more than 20% of its total assets when assuming a temporary defensive position,
in taxable money market instruments or in tax-exempt securities subject to the
federal alternative minimum tax for individual shareholders. Investments in
taxable money market instruments would generally be made under any one of the
following circumstances: (a) pending investment of proceeds of the sale of the
Fund's shares or of portfolio securities, (b) pending settlement of purchases
of portfolio securities and (c) to maintain liquidity for the purpose of
meeting anticipated redemptions.

     The types of taxable money market instruments in which the Fund may invest
are limited to the following short-term fixed-income securities (maturing in
one year or less from the time of purchase): (i) obligations of the United
States Government, its agencies, instrumentalities or authorities; (ii)
commercial paper rated P-1 by Moody's Investors Services, Inc. ("Moody's") or
A-1 by Standard & Poor's Corporation ("S&P"); (iii) certificates of deposit of
domestic banks with assets of $1 billion or more; and (iv) repurchase
agreements with respect to portfolio securities.

     VARIABLE RATE AND FLOATING RATE OBLIGATIONS. The Fund may invest in
Municipal Bonds and Municipal Notes ("Municipal Obligations") of the type
called variable rate. The interest rate payable on a variable rate obligation
is adjusted either at predesignated periodic intervals or whenever there is a
change in the market rate of interest on which the interest rate payable is
based. Other features may include the right whereby the Fund may demand
prepayment of the principal amount of the obligation prior to its stated
maturity (a "demand feature") and the right of the issue to prepay the
principal amount prior to maturity. The principal benefit of a variable rate
obligation is that the interest rate adjustment minimizes changes in the market
value of the obligation. The principal benefit to the Fund of purchasing
obligations with a demand feature is that liquidity, and the ability of the
Fund to obtain repayment of the full principal amount of an obligation prior to
maturity, is enhanced.

     FUTURES CONTRACTS AND OPTIONS ON FUTURES. The Fund may invest in financial
futures contracts ("futures contracts") and related options thereon. These
futures contracts and related options thereon will be used only as a hedge
against anticipated interest rate changes. A futures contract sale creates an
obligation by the Fund, as seller, to deliver the specific type of instrument
called for in the contract at a specified future time for a specified price. A
futures contract purchase would create an obligation by the Fund, as purchaser,
to take delivery of the specific type of financial instrument at a specified
future time at a specified price. The specific securities delivered or taken,
respectively, at settlement date, would not be determined until on or near that
date. The determination would be in accordance with the rules of the exchange
on which the futures contract sale or purchase was effected.


                                       4

<PAGE>

     Although the terms of futures contracts specify actual delivery or receipt
of securities, in most instances the contracts are closed out before the
settlement date without the making or taking of delivery of the securities.
Closing out of a futures contract is usually effected by entering into an
offsetting transaction. An offsetting transaction for a futures contract sale
is effected by the Fund entering into a futures contract purchase for the same
aggregate amount of the specific type of financial instrument at the same
delivery date. If the price in the sale exceeds the price in the offsetting
purchase, the Fund is immediately paid the difference and thus realizes a gain.
If the offsetting purchase price exceeds the sale price, the Fund pays the
difference and realizes a loss. Similarly, the closing out of a futures
contract purchase is effected by the Fund entering into a futures contract
sale. If the offsetting sale price exceeds the purchase price, the Fund
realizes a gain, and if the offsetting sale price is less than the purchase
price, the Fund realizes a loss.

     Unlike a futures contract, which requires the parties to buy and sell a
security on a set date, an option on a futures contract entitles its holder to
decide on or before a future date whether to enter into such a contract (a long
position in the case of a call option and a short position in the case of a put
option). If the holder decides not to enter into the contract, the premium paid
for the contract is lost. Since the value of the option is fixed as the point
of sale, there are no daily payments of cash to reflect the change in the value
of the underlying contract, as discussed below for futures contracts. The value
of the option change is reflected in the net asset value of the particular Fund
holding the options.

     The Fund is required to maintain margin deposits with brokerage firms
through which it effects futures contracts and options thereon. The initial
margin requirements vary according to the type of the underlying security. In
addition, due to current industry practice, daily variations in gains and
losses on open contracts are required to be reflected in cash in the form of
variation margin payments. The Fund may be required to make additional margin
payments during the term of the contract.

     Currently, futures contracts can be purchased on debt securities such as
U.S. Treasury Bills and Bonds, U.S. Treasury Notes with maturities between 61/2
and 10 years, Certificates of the Government National Mortgage Association,
Bank Certificates of Deposit and on a municipal bond index. The Fund may invest
in interest rate futures contracts covering these types of financial
instruments as well as in new types of contracts that become available in the
future.

     Financial futures contracts are traded in an auction environment on the
floors of several Exchanges - principally, the Chicago Board of Trade, the
Chicago Mercantile Exchange and the New York Futures Exchange. Each Exchange
guarantees performance under contract provisions through a clearing
corporation, a nonprofit organization managed by the Exchange membership which
is also responsible for handling daily accounting of deposits or withdrawals of
margin. A risk in employing futures contracts may correlate imperfectly with
the behavior of the cash prices of the Fund's portfolio securities. The
correlation may be distorted by the fact that the futures market is dominated
by short-term traders seeking to profit from the difference between a contract
or security price objective and a short time period. The correlation may be
further distorted since the futures contracts that are being used to hedge are
not based on municipal obligations.

     Another risk is that the Fund's Investment Manager could be incorrect in
its expectations as to the direction or extent of various interest rate
movements or the time span within which the movements take place. For example,
if the Fund sold futures contracts for the sale of securities in anticipation
of an increase in interest rates, and the interest rates went down instead,
causing bond prices to rise, the Fund would lose money on the sale. Put and
call options on financial futures have characteristics similar to Exchange
traded options.

     In addition to the risks associated in investing in options on securities,
there are particular risks associated with investing in options on futures. In
particular, the ability to establish and close out positions on such options
will be subject to the development and maintenance of a liquid secondary
market. It is not certain that such a market will develop.

     The Fund may not enter into futures contracts or related options thereon
if, immediately thereafter, the amount committed to margin plus the amount paid
for option premiums exceeds 5% of the value of the Fund's total assets. There
is no limit, however, on the percentage of the Fund's assets that may be
committed to hedging transactions.


                                       5

     Municipal Bond Index Futures. The Fund may utilize municipal bond index
futures contracts for hedging purposes. The strategies in employing such
contracts will be similar to that discussed above with respect to financial
futures and options thereon. A municipal bond index is a method of reflecting
in a single number the market value of many different municipal bonds and is
designed to be representative of the municipal bond market generally. The index
fluctuates in response to changes in the market values of the bonds included
within the index. Unlike futures contracts on particular financial instruments,
transactions in futures on a municipal bond index will be settled in cash, if
held until the close of trading in the contract. However, like any other
futures contract, a position in the contract may be closed out by a purchase or
sale of an offsetting contract for the same delivery month prior to expiration
of the contract.

     OPTIONS. The Fund may purchase or sell (write) options on debt securities
as a means of achieving additional return or hedging the value of the Fund's
portfolio. The Fund will only buy options listed on national securities
exchanges. The Fund will not purchase options if, as a result, the aggregate
cost of all outstanding options exceeds 10% of the Fund's total assets.

     Presently there are no options on tax-exempt securities traded on national
securities exchanges. The Fund will not invest in options on debt securities in
the coming year or until such time as they become available on national
securities exchanges.

     A call option is a contract that gives the holder of the option the right
to buy from the writer of the call option, in return for a premium, the
security underlying the option at a specified exercise price at any time during
the term of the option. The writer of the call option has the obligation, upon
exercise of the option, to deliver the underlying security upon payment of the
exercise price during the option period. A put option is a contract that gives
the holder of the option the right to sell to the writer, in return for a
premium, the underlying security at a specified price during the term of the
option. The writer of the put has the obligation to buy the underlying security
upon exercise, at the exercise price during the option period.


     The Fund will only write covered call or covered put options listed on
national exchanges. The Fund may not write covered options in an amount
exceeding 20% of the value of the total assets of the Fund. A call option is
"covered" if the Fund owns the underlying security subject to the option or has
an absolute and immediate right to acquire that security without additional
cash consideration (or for additional consideration (in cash, Treasury bills or
other liquid portfolio securities) held in a segregated account on the Fund's
books) upon conversion or exchange of other securities held in its portfolio. A
call option is also covered if the Fund holds a call on the same security as
the call written, where the exercise price of the call held is (i) equal to or
less than the exercise price of the call written or (ii) greater than the
exercise price of the call written if the difference is maintained by the Fund
in cash, Treasury bills or other liquid portfolio securities in a segregated
account on the Fund's books. A put option is "covered" if the Fund maintains
cash, Treasury bills or other liquid portfolio securities with a value equal to
the exercise price in a segregated account on the Fund's books, or holds a put
on the same security as the put written where the exercise price of the put
held is equal to or greater than the exercise price of the put written.


     If the Fund has written an option, it may terminate its obligation by
effecting a closing purchase transaction. This is accomplished by purchasing an
option of the same series as the option previously written. However, once the
Fund has been assigned an exercise notice, the Fund will be unable to effect a
closing purchase transaction. Similarly, if the Fund is the holder of an
option, it may liquidate its position by effecting a closing sale transaction.
This is accomplished by selling an option of the same fund as the option
previously purchased. There can be no assurance that either a closing purchase
or sale transaction on behalf of the Fund can be effected when the Fund so
desires.

     The Fund will realize a profit from a closing transaction if the price of
the transaction is less than the premium received from writing the option or is
more than the premium paid to purchase the option; the Fund will realize a loss
from a closing transaction if the price of the transaction is more than the
premium received from writing the option or is less than the premium paid to
purchase the option. Since call option prices generally reflect increases in
the price of the underlying security, any loss resulting from the purchase of a
call option may also be wholly or partially offset by unrealized appreciation
of the underlying security. If a put option written by the Fund is exercised,
the Fund may incur a loss equal to


                                       6


<PAGE>
<PAGE>

the difference between the exercise price of the option and the sum of the sale
price of the underlying security plus the premiums received from the sale of
the option. Other principal factors affecting the market value of a put or a
call option include supply and demand, interest rates, the current market price
and price volatility of the underlying security and the time remaining until
the expiration date.

     An option position may be closed out only on an exchange which provides a
secondary market for an option of the same series. Although the Fund will
generally purchase or write only those options for which there appears to be an
active secondary market, there is no assurance that a liquid secondary market
on an exchange will exist for any particular option. In such event, it might
not be possible to effect closing transactions in particular options, so that
the Fund would have to exercise its options in order to realize any profit and
would incur brokerage commission upon the exercise of call options and upon
covered call option writer is unable to effect a closing purchase transaction
in a secondary market, it will not be able to sell the underlying security
until the option expires or it delivers the underlying security upon exercise.


     If the Fund maintains a short position in a futures contract or has sold a
call option in a futures contract, it will cover this position by holding, in a
segregated account maintained on the books of the Fund, cash, U.S. government
securities or other liquid portfolio securities equal in value (when added to
any initial or variation margin on deposit) to the market value of the
securities underlying the futures contract or the exercise price of the option.
Such a position may also be covered by owning the securities underlying the
futures contract (in the case of a stock index futures contract a portfolio of
securities substantially replicating the relevant index), or by holding a call
option permitting the Fund to purchase the same contract at a price no higher
than the price at which the short position was established.

     In addition, if the Fund holds a long position in a futures contract or
has sold a put option on a futures contract, it will hold cash, U.S. government
securities or other liquid portfolio securities equal to the purchase price of
the contract or the exercise price of the put option (less the amount of
initial or variation margin on deposit) in a segregated account maintained on
the books of the Fund. Alternatively, the Fund could cover its long position by
purchasing a put option on the same futures contract with an exercise price as
high or higher than the price of the contract held by the Fund.

     REPURCHASE AGREEMENTS. The Fund may invest in repurchase agreements. When
cash may be available for only a few days, it may be invested by the Fund in
repurchase agreements until such time as it may otherwise be invested or used
for payments of obligations of the Fund. These agreements, which may be viewed
as a type of secured lending by the Fund, typically involve the acquisition by
the Fund of debt securities from a selling financial institution such as a
bank, savings and loan association or broker-dealer. The agreement provides
that the Fund will sell back to the institution, and that the institution will
repurchase, the underlying security serving as collateral at a specified price
and at a fixed time in the future, usually not more than seven days from the
date of purchase. The collateral will be marked-to-market daily to determine
that the value of the collateral, as specified in the agreement, does not
decrease below the purchase price plus accrued interest. If such decrease
occurs, additional collateral will be requested and, when received, added to
the account to maintain full collateralization. The Fund will accrue interest
from the institution until the time when the repurchase is to occur. Although
this date is deemed by the Fund to be the maturity date of a repurchase
agreement, the maturities of securities subject to repurchase agreements are
not subject to any limits.


     While repurchase agreements involve certain risks not associated with
direct investments in debt securities, the Fund follows procedures designed to
minimize such risks. These procedures include effecting repurchase transactions
only with large, well-capitalized and well-established financial institutions
whose financial condition will be continually monitored by the Investment
Manager subject to procedures established by the Trustees. In addition, as
described above, the value of the collateral underlying the repurchase
agreement will be at least equal to the repurchase price, including any accrued
interest earned on the repurchase agreement. In the event of a default or
bankruptcy by a selling financial institution, the Fund will seek to liquidate
such collateral. However, the exercising of the Fund's right to liquidate such
collateral could involve certain costs or delays and, to the extent that
proceeds form any sale upon a default of the obligation to repurchase were less
than the repurchase price, the


                                       7
<PAGE>

Fund could suffer a loss. It is the current policy of the Fund not to invest in
repurchase agreements that do not mature within seven days if any such
investment, together with any other illiquid assets held by the Fund, amounts
to more than 10% of its net assets.

     LENDING PORTFOLIO SECURITIES. The Fund may lend its portfolio securities
to brokers, dealers and other financial institutions, provided that the loans
are callable at any time by the Fund, and are at all times secured by cash or
cash equivalents, which are maintained in a segregated account pursuant to
applicable regulations and that are equal to at least 100% of the market value,
determined daily, of the loaned securities. The advantage of these loans is
that the Fund continues to receive the income on the loaned securities while at
the same time earning interest on the cash amounts deposited as collateral,
which will be invested in short-term obligations. The Fund will not lend more
than 25% of the value of its total assets.

     As with any extensions of credit, there are risks of delay in recovery
and, in some cases, even loss of rights in the collateral should the borrower
of the securities fail financially. However, these loans of portfolio
securities will only be made to firms deemed by the Fund's management to be
creditworthy and when the income which can be earned from such loans justifies
the attendant risks. Upon termination of the loan, the borrower is required to
return the securities to the Fund. Any gain or loss in the market price during
the loan period would inure to the Fund.

     When voting or consent rights which accompany loaned securities pass to
the borrower, the Fund will follow the policy of calling the loaned securities,
to be delivered within one day after notice, to permit the exercise of the
rights if the matters involved would have a material effect on the Fund's
investment in the loaned securities. The Fund will pay reasonable finder's,
administrative and custodial fees in connection with a loan of its securities.

     WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS. From
time to time the Fund may purchase securities on a when-issued or delayed
delivery basis or may purchase or sell securities on a forward commitment
basis. When these transactions are negotiated, the price is fixed at the time
of the commitment, but delivery and payment can take place a month or more
after the date of commitment. While the Fund will only purchase securities on a
when-issued, delayed delivery or forward commitment basis with the intention of
acquiring the securities, the Fund may sell the securities before the
settlement date, if it is deemed advisable. The securities so purchased or sold
are subject to market fluctuation and no interest or dividends accrue to the
purchaser prior to the settlement date.

     At the time the Fund makes the commitment to purchase or sell securities
on a when-issued, delayed delivery or forward commitment basis, it will record
the transaction and thereafter reflect the value, each day, of such security
purchased, or if a sale, the proceeds to be received, in determining its net
asset value. At the time of delivery of the securities, their value may be more
or less than the purchase or sale price. An increase in the percentage of the
Fund's assets committed to the purchase of securities on a when-issued, delayed
delivery or forward commitment basis may increase the volatility of its net
asset value. The Fund will also establish a segregated account on the Fund's
books in which it will continually maintain cash or cash equivalents or other
liquid portfolio securities equal in value to commitments to purchase
securities on a when-issued, delayed delivery or forward commitment basis.

     WHEN, AS AND IF ISSUED SECURITIES. The Fund may purchase securities on a
"when, as and if issued" basis under which the issuance of the security depends
upon the occurrence of a subsequent event, such as approval of a merger,
corporate reorganization or debt restructuring. The commitment for the purchase
of any such security will not be recognized in the portfolio of the Fund until
the Investment Manager determines that issuance of the security is probable. At
that time, the Fund will record the transaction and, in determining its net
asset value, will reflect the value of the security daily. At that time, the
Fund will also establish a segregated account on the Fund's books in which it
will maintain cash or cash equivalents or other liquid portfolio securities
equal in value to recognized commitments for such securities.

     The value of the Fund's commitments to purchase the securities of any one
issuer, together with the value of all securities of such issuer owned by the
Fund, may not exceed 5% of the value of the Fund's


                                       8

<PAGE>

total assets at the time the initial commitment to purchase such securities is
made. An increase in the percentage of the Fund's assets committed to the
purchase of securities on a "when, as and if issued" basis may increase the
volatility of its net asset value. The Fund may also sell securities on a
"when, as and if issued" basis provided that the issuance of the security will
result automatically from the exchange or conversion of a security owned by the
Fund at the time of sale.


     YEAR 2000. The investment management services provided to the Fund by the
Investment Manager and the services provided to shareholders by the Distributor
and the Transfer Agent depend on the smooth functioning of their computer
systems. Many computer software systems in use today were designed in such a
way that they may not be able to recognize the year 2000, but revert to 1900 or
some other date, due to the manner in which dates were encoded and calculated.
That failure could have a negative impact on the handling of securities trades,
pricing and account services.

     Improperly functioning trading systems may result in settlement problems
and liquidity issues. Governmental data processing errors could result in
overall economic uncertainties. Operations ran smoothly from the last week in
December through the first few weeks of January, but the year 2000 issue may
yet have an adverse impact on financial market participants and other entities,
including the issuers whose securities are contained in the Fund's portfolio.




C. FUND POLICIES/INVESTMENT RESTRICTIONS

     The investment objective, policies and restrictions listed below have been
adopted by the Fund as fundamental policies. Under the Investment Company Act
of 1940 (the "Investment Company Act"), a fundamental policy may not be changed
without the vote of a majority of the outstanding voting securities of the
Fund. The Investment Company Act defines a majority as the lesser of (a) 67% or
more of the shares present at a meeting of shareholders, if the holders of 50%
of the outstanding shares of the Fund are present or represented by proxy; or
(b) more than 50% of the outstanding shares of the Fund.

     In addition, for purposes of the following restrictions: (a) an "issuer"
of a security is the entity whose assets and revenues are committed to the
payment of interest and principal on that particular security, provided that
the guarantee of a security will be considered a separate security and provided
further that a guarantee of a security shall not be deemed a security issued by
the guarantor if the value of all securities guaranteed by the guarantor and
owned by the Fund does not exceed 10% of the value of the total assets of the
Fund; (b) a "taxable security" is any security the interest on which is subject
to federal income tax; and (c) all percentage limitations apply immediately
after a purchase or initial investment, and any subsequent change in any
applicable percentage resulting from market fluctuations or other changes in
total or net assets does not require elimination of any security from the
portfolio.

     The Fund will:

    1. Seek to provide a high level of current income exempt from federal
       income tax, consistent with the preservation of capital.

     The Fund may not:

    1. Invest more than 5% of the value of its total assets in the securities
       of any one issuer (other than obligations issued or guaranteed by the
       United States Government, its agencies or instrumentalities).

    2. Purchase more than 10% of all outstanding taxable debt securities of
       any one issuer (other than obligations issued, or guaranteed as to
       principal and interest by, the United States Government, its agencies or
       instrumentalities).

    3. Invest more than 25% of the value of its total assets in taxable
       securities of issuers in any one industry (industrial development and
       pollution control bonds are grouped into industries based upon the
       business in which the issuers of such obligations are engaged). This
       restriction does not apply to obligations issued or guaranteed by the
       United States Government, its agencies or instrumentalities or to cash
       equivalents.


                                       9


<PAGE>
<PAGE>

    4. Invest more than 5% of the value of its total assets in taxable
       securities of issuers having a record, together with predecessors, of
       less than three years of continuous operation. This restriction shall not
       apply to any obligations of the United States Government, its agencies or
       instrumentalities.

    5. Invest in common stock.

    6. Write, purchase or sell puts, calls, or combinations thereof, except
       for options on futures contracts or options on debt securities.


    7. Invest in securities of any issuer, if, to the knowledge of the Fund,
       any officer or trustee of the Fund or of the Investment Manager owns more
       than 1/2 of 1% of the outstanding securities of the issuer, and the
       officers and trustees who own more than 1/2 of 1% own in the aggregate
       more than 5% of the outstanding securities of the issuer.


    8. Purchase or sell real estate or interests therein, although it may
       purchase securities secured by real estate or interests therein.


    9. Purchase or sell commodities except that the Fund may purchase
       financial futures contracts and related options.


   10. Borrow money, except that the Fund may borrow from a bank for temporary
       or emergency purposes in amounts not exceeding 5% (taken at the lower of
       cost or current value) of the value of its total assets (not including
       the amount borrowed).


   11. Pledge its assets or assign or otherwise encumber them except to secure
       permitted borrowing. However, for the purpose of this restriction,
       collateral arrangements with respect to the writing of options and
       collateral arrangements with respect to initial margin for futures are
       not deemed to be pledges of assets.


   12. Issue senior securities as defined in the Investment Company Act,
       except insofar as the Fund may be deemed to have issued a senior security
       by reason of: (a) entering into any repurchase agreement; (b) purchasing
       any securities on a when-issued or delayed delivery basis; (c) purchasing
       or selling any financial futures contracts; (d) borrowing money; or (e)
       lending portfolio securities.


   13. Make loans of money or securities, except: (a) by the purchase of debt
       obligations and (b) by investment in repurchase agreements.


   14. Make short sales of securities.


   15. Purchase securities on margin, except for such short-term loans as are
       necessary for the clearance of purchases of portfolio securities.


   16. Engage in the underwriting of securities, except insofar as the Fund
       may be deemed an underwriter under the Securities Act in disposing of a
       portfolio security.


   17. Invest for the purpose of exercising control or management of any
       other issuer.


   18. Purchase oil, gas or other mineral leases, rights or royalty contracts,
       or exploration or development programs.


   19. Purchase securities of other investment companies, except in connection
       with a merger, consolidation, reorganization or acquisition of assets.


     Notwithstanding any other investment policy or restriction, the Fund may
seek to achieve its investment objective by investing all or substantially all
of its assets in another investment company having substantially the same
investment objective and policies as the Fund.

III. MANAGEMENT OF THE FUND
- --------------------------------------------------------------------------------

A. BOARD OF TRUSTEES


     The Board of Trustees of the Fund oversees the management of the Fund but
does not itself manage the Fund. The Trustees review various services provided
by or under the direction of the Investment Manager to ensure that the Fund's
general investment policies and programs are properly carried out. The Trustees
also conduct their review to ensure that administrative services are provided
to the Fund in a satisfactory manner.


     Under state law, the duties of the Trustees are generally characterized as
a duty of loyalty and a duty of care. The duty of loyalty requires a Trustee to
exercise his or her powers in the interest of the Fund and not the Trustee's
own interest or the interest of another person or organization. A Trustee
satisfies his or her duty of care by acting in good faith with the care of an
ordinarily prudent person and in a manner the Trustee reasonably believes to be
in the best interest of the Fund and its shareholders.


B. MANAGEMENT INFORMATION



     TRUSTEES AND OFFICERS. The Board of the Fund consists of eight (8)
Trustees. These same individuals also serve as directors or trustees for all of
the Morgan Stanley Dean Witter Funds. Six Trustees (75% of the total number)
have no affiliation or business connection with the Investment Manager or any
of its affiliated persons and do not own any stock or other securities issued
by the Investment Manager's parent company, MSDW. These are the
"non-interested" or "independent" Trustees. The other two Trustees (the
"management Trustees") are affiliated with the Investment Manager.


     The Trustees and executive officers of the Fund, their principal business
occupations during the last five years and their affiliations, if any, with the
Investment Manager, and with the Morgan Stanley Dean Witter Funds (there were
93 such Funds as of the calendar year ended December 31, 1999), are shown
below.

     INDEPENDENT DIRECTORS/TRUSTEES AND THE COMMITTEES. Law and regulation
establish both general guidelines and specific duties for the independent
directors/trustees. The Morgan Stanley Dean Witter Funds seek as independent
directors/trustees individuals of distinction and experience in business and
finance, government service or academia; these are people whose advice and
counsel are in demand by others and for whom there is often competition. To
accept a position on the Funds' boards, such individuals may reject other
attractive assignments because the Funds make substantial demands on their
time. All of the independent directors/trustees serve as members of the Audit
Committee. In addition, three of the directors/trustees, including two
independent directors/trustees, serve as members of the Derivatives Committee
and the Insurance Committee.

     The independent directors/trustees are charged with recommending to the
full board approval of management, advisory and administration contracts, Rule
12b-1 plans and distribution and underwriting agreements; continually reviewing
Fund performance; checking on the pricing of portfolio securities, brokerage
commissions, transfer agent costs and performance, and trading among Funds in
the same complex; and approving fidelity bond and related insurance coverage
and allocations, as well as other matters that arise from time to time. The
independent directors/trustees are required to select and nominate individuals
to fill any independent director/trustee vacancy on the board of any Fund that
has a Rule 12b-1 plan of distribution. Most of the Morgan Stanley Dean Witter
Funds have a Rule 12b-1 plan.

     The Audit Committee is charged with recommending to the full board the
engagement or discharge of the Fund's independent accountants; directing
investigations into matters within the scope of the independent accountants'
duties, including the power to retain outside specialists; reviewing with the
independent accountants the audit plan and results of the auditing engagement;
approving professional services provided by the independent accountants and
other accounting firms prior to the performance of the services; reviewing the
independence of the independent accountants; considering the range of audit and
non-audit fees; reviewing the adequacy of the Fund's system of internal
controls; and preparing and submitting Committee meeting minutes to the full
board.



                                       14
<PAGE>


     The board of each Fund has a Derivatives Committee to approve parameters
for and monitor the activities of the Fund with respect to derivative
investments, if any, made by the Fund.

     Finally, the board of each Fund has formed an Insurance Committee to
review and monitor the insurance coverage maintained by the Fund.

     ADVANTAGES OF HAVING SAME INDIVIDUALS AS INDEPENDENT DIRECTORS/TRUSTEES
FOR ALL MORGAN STANLEY DEAN WITTER FUNDS. The independent directors/trustees
and the Funds' management believe that having the same independent
directors/trustees for each of the Morgan Stanley Dean Witter Funds avoids the
duplication of effort that would arise from having different groups of
individuals serving as independent directors/trustees for each of the Funds or
even of sub-groups of Funds. They believe that having the same individuals
serve as independent directors/trustees of all the Funds tends to increase
their knowledge and expertise regarding matters which affect the Fund complex
generally and enhances their ability to negotiate on behalf of each Fund with
the Fund's service providers. This arrangement also precludes the possibility
of separate groups of independent directors/trustees arriving at conflicting
decisions regarding operations and management of the Funds and avoids the cost
and confusion that would likely ensue. Finally, having the same independent
directors/trustees serve on all Fund boards enhances the ability of each Fund
to obtain, at modest cost to each separate Fund, the services of independent
directors/trustees, of the caliber, experience and business acumen of the
individuals who serve as independent directors/trustees of the Morgan Stanley
Dean Witter Funds.


     TRUSTEE AND OFFICER INDEMNIFICATION. The Fund's Declaration of Trust
provides that no Trustee, officer, employee or agent of the Fund is liable to
the Fund or to a shareholder, nor is any Trustee, officer, employee or agent
liable to any third persons in connection with the affairs of the Fund, except
as such liability may arise from his/her or its own bad faith, willful
misfeasance, gross negligence or reckless disregard of his/her or its duties.
It also provides that all third persons shall look solely to the Fund property
for satisfaction of claims arising in connection with the affairs of the Fund.
With the exceptions stated, the Declaration of Trust provides that a Trustee,
officer, employee or agent is entitled to be indemnified against all liability
in connection with the affairs of the Fund.


C. COMPENSATION


     The Fund pays each Independent Trustee an annual fee of $800 plus a per
meeting fee of $50 for meetings of the Board of Trustees, the Independent
Trustees or Committees of the Board of Trustees attended by the Trustee (the
Fund pays the Chairman of the Audit Committee an additional annual fee of $750
and the Chairmen of the Derivatives and Insurance Committees additional annual
fees of $500). If a Board meeting and a meeting of the Independent Trustees or
a Committee meeting, or a meeting of the Independent Trustees and/or more than
one Committee meeting, take place on a single day, the Trustees are paid a
single meeting fee by the Fund. The Fund also reimburses such Trustees for
travel and other out-of-pocket expenses incurred by them in connection with
attending such meetings. Trustees and officers of the Fund who are or have been
employed by the Investment Manager or an affiliated company receive no
compensation or expense reimbursement from the Fund for their services as
Trustee.

     The following table illustrates the compensation that the Fund paid to its
Independent Trustees for the fiscal year ended December 31, 1999.

     As of the date of this Statement of Additional Information, 55 of the
Morgan Stanley Dean Witter Funds, including the Fund, have adopted a retirement
program under which an independent director/  trustee who retires after serving
for at least five years (or such lesser period as may be determined by the
Board) as an independent director/trustee of any Morgan Stanley Dean Witter
Fund that has adopted the retirement program (each such Fund referred to as an
"Adopting Fund" and each such director/  trustee referred to as an "Eligible
Director/Trustee") is entitled to retirement payments upon reaching the
eligible retirement age (normally, after attaining age 72). Annual payments are
based upon length of service.


     Currently, upon retirement, each Eligible Director/Trustee is entitled to
receive from the Adopting Fund, commencing as of his or her retirement date and
continuing for the remainder of his or her life, an annual retirement benefit
(the "Regular Benefit") equal to 30.22% of his or her Eligible Compensation
plus 0.5036667% of such Eligible Compensation for each full month of service as
an independent director/trustee of any Adopting Fund in excess of five years up
to a maximum of 60.44% after ten years of service. The foregoing percentages
may be changed by the board.(1) "Eligible Compensation" is one-fifth of the
total compensation earned by such Eligible Director/Trustee for service to the
Adopting Fund in the five year period prior to the date of the Eligible
Director/Trustee's retirement. Benefits under the retirement program are
accrued as expenses on the books of the Adopting Funds. Such benefits are not
secured or funded by the Adopting Funds.


     The following table illustrates the retirement benefits accrued to the
Fund's Independent Trustees by the Fund for the fiscal year ended December 31,
1999 and by the 55 Morgan Stanley Dean Witter Funds (including the Fund) for
the year ended December 31, 1999, and the estimated retirement benefits for the
Independent Trustees, to commence upon their retirement, from the Fund as of
December 31, 1999 and from the 55 Morgan Stanley Dean Witter Funds as of
December 31, 1999.



- ----------

(1)   An Eligible Director/Trustee may elect alternative payments of his or her
      retirement benefits based upon the combined life expectancy of the
      Eligible Director/Trustee and his or her spouse on the date of such
      Eligible Director/Trustee's retirement. In addition, the Eligible
      Director/Trustee may elect that the surviving spouse's periodic payment
      of benefits will be equal to a lower percentage of the periodic amount
      when both spouses were alive. The amount estimated to be payable under
      this method, through the remainder of the later of the lives of the
      Eligible Director/Trustee and spouse, will be the actuarial equivalent of
      the Regular Benefit.

V. INVESTMENT MANAGEMENT AND OTHER SERVICES
- --------------------------------------------------------------------------------

A. INVESTMENT MANAGER


     The Investment Manager to the Fund is Morgan Stanley Dean Witter Advisors
Inc., a Delaware corporation, whose address is Two World Trade Center, New
York, NY 10048. The Investment Manager is a wholly-owned subsidiary of MSDW, a
Delaware corporation. MSDW is a preeminent global financial services firm that
maintains leading market positions in each of its three primary businesses:
securities, asset management and credit services.

     Pursuant to an Investment Management Agreement (the "Management
Agreement") with the Investment Manager, the Fund has retained the Investment
Manager to provide administrative services and manage the investment of the
Fund's assets, including the placing of orders for the purchase and sale of
portfolio securities. The Fund pays the Investment Manager monthly compensation
calculated daily by applying the following annual rates to the net assets of
the Fund determined as of the close of each business day: 0.50% of the portion
of the daily net assets not exceeding $500 million; 0.425% of the portion of
the daily net assets exceeding $500 million but not exceeding $750 million;
0.375% of the portion of the daily net assets exceeding $750 million but not
exceeding $1 billion; 0.35% of the portion of the daily net assets exceeding $1
billion but not exceeding $1.25 billion; and 0.325% of the portion of the daily
net assets exceeding $1.25 billion. The management fee is allocated among the
Classes pro rata based on the net assets of the Fund attributable to each
Class. For the fiscal years ended December 31, 1997, 1998 and 1999, the
Investment Manager accrued total compensation under the Management Agreement in
the amounts of $5,004,702, $5,139,570 and $4,908,427, respectively.



                                       17
<PAGE>

     The Investment Manager has retained its wholly-owned subsidiary, MSDW
Services Company, to perform administrative services for the Fund.


B. PRINCIPAL UNDERWRITER

     The Fund's principal underwriter is the Distributor (which has the same
address as the Investment Manager). In this capacity, the Fund's shares are
distributed by the Distributor. The Distributor has entered into a selected
dealer agreement with Dean Witter Reynolds, which through its own sales
organization sells shares of the Fund. In addition, the Distributor may enter
into similar agreements with other selected broker-dealers. The Distributor, a
Delaware corporation, is a wholly-owned subsidiary of MSDW.


     The Distributor bears all expenses it may incur in providing services
under the Distribution Agreement. These expenses include the payment of
commissions for sales of the Fund's shares and incentive compensation to
Financial Advisors, the cost of educational and/or business-related trips, and
educational and/or promotional and business-related expenses. The Distributor
also pays certain expenses in connection with the distribution of the Fund's
shares, including the costs of preparing, printing and distributing advertising
or promotional materials, and the costs of printing and distributing
prospectuses and supplements thereto used in connection with the offering and
sale of the Fund's shares. The Fund bears the costs of initial typesetting,
printing and distribution of prospectuses and supplements thereto to
shareholders. The Fund also bears the costs of registering the Fund and its
shares under federal and state securities laws and pays filing fees in
accordance with state securities laws.


     The Fund and the Distributor have agreed to indemnify each other against
certain liabilities, including liabilities under the Securities Act. Under the
Distribution Agreement, the Distributor uses its best efforts in rendering
services to the Fund, but in the absence of willful misfeasance, bad faith,
gross negligence or reckless disregard of its obligations, the Distributor is
not liable to the Fund or any of its shareholders for any error of judgment or
mistake of law or for any act or omission or for any losses sustained by the
Fund or its shareholders.



C. SERVICES PROVIDED BY THE INVESTMENT MANAGER


     The Investment Manager manages the investment of the Fund's assets,
including the placing of orders for the purchase and sale of portfolio
securities. The Investment Manager obtains and evaluates the information and
advice relating to the economy, securities markets, and specific securities as
it considers necessary or useful to continuously manage the assets of the Fund
in a manner consistent with its investment objective.

     Under the terms of the Management Agreement, in addition to managing the
Fund's investments, the Investment Manager maintains certain of the Fund's
books and records and furnishes, at its own expense, the office space,
facilities, equipment, clerical help, bookkeeping and certain legal services as
the Fund may reasonably require in the conduct of its business, including the
preparation of prospectuses, proxy statements and reports required to be filed
with federal and state securities commissions (except insofar as the
participation or assistance of independent accountants and attorneys is, in the
opinion of the Investment Manager, necessary or desirable). In addition, the
Investment Manager pays the salaries of all personnel, including officers of
the Fund, who are employees of the Investment Manager. The Investment Manager
also bears the cost of telephone service, heat, light, power and other
utilities provided to the Fund.

     Expenses not expressly assumed by the Investment Manager under the
Management Agreement or by the Distributor, will be paid by the Fund. These
expenses will be allocated among the four Classes of shares pro rata based on
the net assets of the Fund attributable to each Class, except as described
below. Such expenses include, but are not limited to: expenses of the Plan of
Distribution pursuant to Rule 12b-1; charges and expenses of any registrar,
custodian, stock transfer and dividend disbursing agent; brokerage commissions;
taxes; engraving and printing share certificates; registration costs of the
Fund and its shares under federal and state securities laws; the cost and
expense of printing, including


                                       18

<PAGE>

typesetting, and distributing prospectuses of the Fund and supplements thereto
to the Fund's shareholders; all expenses of shareholders' and Trustees'
meetings and of preparing, printing and mailing of proxy statements and reports
to shareholders; fees and travel expenses of Trustees or members of any
advisory board or committee who are not employees of the Investment Manager or
any corporate affiliate of the Investment Manager; all expenses incident to any
dividend, withdrawal or redemption options; charges and expenses of any outside
service used for pricing of the Fund's shares; fees and expenses of legal
counsel, including counsel to the Trustees who are not interested persons of
the Fund or of the Investment Manager (not including compensation or expenses
of attorneys who are employees of the Investment Manager); fees and expenses of
the Fund's independent accountants; membership dues of industry associations;
interest on Fund borrowings; postage; insurance premiums on property or
personnel (including officers and Trustees) of the Fund which inure to its
benefit; extraordinary expenses (including, but not limited to, legal claims
and liabilities and litigation costs and any indemnification relating thereto);
and all other costs of the Fund's operation. The 12b-1 fees relating to a
particular Class will be allocated directly to that Class. In addition, other
expenses associated with a particular Class (except advisory or custodial fees)
may be allocated directly to that Class, provided that such expenses are
reasonably identified as specifically attributable to that Class and the direct
allocation to that Class is approved by the Trustees.


     The Management Agreement provides that in the absence of willful
misfeasance, bad faith, gross negligence or reckless disregard of its
obligations thereunder, the Investment Manager is not liable to the Fund or any
of its investors for any act or omission by the Investment Manager or for any
losses sustained by the Fund or its investors.



     The Management Agreement will remain in effect from year to year, provided
continuance of the Management Agreement is approved at least annually by the
vote of the holders of a majority, as defined in the Investment Company Act, of
the outstanding shares of the Fund, or by the Trustees; provided that in either
event such continuance is approved annually by the vote of a majority of the
Trustees, including a majority of the Independent Trustees.



D. DEALER REALLOWANCES


     Upon notice to selected broker-dealers, the Distributor may reallow up to
the full applicable front-end sales charge during periods specified in such
notice. During periods when 90% or more of the sales charge is reallowed, such
selected broker-dealers may be deemed to be underwriters as that term is
defined in the Securities Act.



E. RULE 12B-1 PLAN



     The Fund has adopted a Plan of Distribution pursuant to Rule 12b-1 under
the Investment Company Act (the "Plan") pursuant to which each Class, other
than Class D, pays the Distributor compensation accrued daily and payable
monthly at the following annual rates: 0.25%, 0.60% and 0.70% of the average
daily net assets of Class A, Class B and Class C, respectively.


                                       19
<PAGE>


     The Distributor also receives the proceeds of front-end sales charges
("FSCs") and of contingent deferred sales charges ("CDSCs") imposed on certain
redemptions of shares, which are separate and apart from payments made pursuant
to the Plan. The Distributor has informed the Fund that it and/or Dean Witter
Reynolds received the proceeds of CDSCs and FSCs, for the last three fiscal
years ended December 31, in approximate amounts as provided in the table below
(the Distributor did not retain any of these amounts).

- ----------

(1)   FSCs apply to Class A only.

(2)   Prior to July 27, 1998 the Fund charged an FSC. On July 28, 1997 existing
      shares of the Fund were designated Class D shares, which have no FSC.



     The Distributor has informed the Fund that the entire fee payable by Class
A and a portion of the fees payable by each of Class B and Class C each year
pursuant to the Plan equal to 0.15% of the average daily net assets of Class B
and 0.25% of the average daily net assets of Class C are currently each
characterized as a "service fee" under the Rules of the National Association of
Securities Dealers, Inc. (of which the Distributor is a member). The "service
fee" is a payment made for personal service and/or the maintenance of
shareholder accounts. The remaining portion of the Plan fees payable by a
Class, if any, is characterized as an "asset-based sales charge" as such is
defined by the Rules of the Association.


     Under the Plan and as required by Rule 12b-1, the Trustees receive and
review promptly after the end of each calendar quarter a written report
provided by the Distributor of the amounts expended under the Plan and the
purpose for which such expenditures were made. Class B shares of the Fund
accrued amounts payable to the Distributor under the Plan, during the fiscal
year ended December 31, 1999, of $855,483. This amount is equal to 0.60% of the
average daily net assets of Class B for the fiscal year. For the fiscal year
ended December 31, 1999, Class A and Class C shares of the Fund accrued
payments under the Plan amounting to $23,738 and $67,457, respectively, which
amounts are equal to 0.13% and 0.70% of the average daily net assets of Class A
and Class C, respectively, for the fiscal year.


     The Plan was adopted in order to permit the implementation of the Fund's
method of distribution. Under this distribution method the Fund offers four
Classes, each with a different distribution arrangement.

     With respect to Class A shares, Dean Witter Reynolds compensates its
Financial Advisors by paying them, from proceeds of the FSC, commissions for
the sale of Class A shares, currently a gross sales credit of up to 4.0% of the
amount sold (except as provided in the following sentence) and an annual
residual commission, currently a residual of up to 0.15% of the current value
of the respective accounts for which they are the Financial Advisors or dealers
of record in all cases. On orders of $1 million or more (for which no sales
charge was paid), the Investment Manager compensates Financial Advisors by
paying them, from its own funds, a gross sales credit of 1.0% of the amount
sold.

     With respect to Class B shares, Dean Witter Reynolds compensates its
Financial Advisors by paying them, from its own funds, commissions for the sale
of Class B shares, currently a gross sales credit of up to 4.0% of the amount
sold and an annual residual commission, currently a residual of up to 0.15% of
the current value (not including reinvested dividends or distributions) of the
amount sold in all cases.

     With respect to Class C shares, Dean Witter Reynolds compensates its
Financial Advisors by paying them, from its own funds, commissions for the sale
of Class C shares, currently a gross sales credit of up to 1.0% of the amount
sold and an annual residual commission, currently up to 0.70% of the current
value of the respective accounts for which they are the Financial Advisors of
record.


                                       20

<PAGE>

     With respect to Class D shares other than shares held by participants in
the Investment Manager's mutual fund asset allocation program, the Investment
Manager compensates Dean Witter Reynolds's Financial Advisors by paying them,
from its own funds, commissions for the sale of Class D shares, currently a
gross sales credit of up to 1.0% of the amount sold. There is a chargeback of
100% of the amount paid if the Class D shares are redeemed in the first year
and a chargeback of 50% of the amount paid if the Class D shares are redeemed
in the second year after purchase. The Investment Manager also compensates Dean
Witter Reynolds's Financial Advisors by paying them, from its own funds, an
annual residual commission, currently up to 0.10% of the current value of the
respective accounts for which they are the Financial Advisors of record (not
including accounts of participants in the Investment Manager's mutual fund
asset allocation program).

     The gross sales credit is a charge which reflects commissions paid by Dean
Witter Reynolds to its Financial Advisors and Dean Witter Reynolds's
Fund-associated distribution-related expenses, including sales compensation,
and overhead and other branch office distribution-related expenses including
(a) the expenses of operating Dean Witter Reynolds's branch offices in
connection with the sale of Fund shares, including lease costs, the salaries
and employee benefits of operations and sales support personnel, utility costs,
communications costs and the costs of stationery and supplies, (b) the costs of
client sales seminars, (c) travel expenses of mutual fund sales coordinators to
promote the sale of Fund shares and (d) other expenses relating to branch
promotion of Fund sales.


     The Investment Manager pays a retention fee to Financial Advisors at an
annual rate of 0.05% of the value of shares of the Fund sold after January 1,
2000 and held for at least one year. Shares purchased through the reinvestment
of dividends will be eligible for a retention fee, provided that such dividends
were earned on shares otherwise eligible for a retention fee payment. Shares
owned in variable annuities, closed-end fund shares and shares held in 401(k)
plans where the Transfer Agent or Dean Witter Reynolds' Retirement Plan
Services is either recordkeeper or trustee are not eligible for a retention
fee.

     For the first year only, the retention fee is paid on any shares of the
Fund sold after January 1, 2000 and held by shareholders on December 31, 2000.

     The retention fees are paid by the Investment Manager from its own assets,
which may include profits from investment management fees payable under the
Management Agreement, as well as from borrowed funds.

     The distribution fee that the Distributor receives from the Fund under the
Plan, in effect, offsets distribution expenses incurred under the Plan on
behalf of the Fund and, in the case of Class B shares, opportunity costs, such
as the gross sales credit and an assumed interest charge thereon ("carrying
charge"). These expenses may include the cost of Fund-related educational
and/or business-related trips or payment of Fund-related educational and/or
promotional expenses of Financial Advisors. In the Distributor's reporting of
the distribution expenses to the Fund, in the case of Class B shares, such
assumed interest (computed at the "broker's call rate") has been calculated on
the gross credit as it is reduced by amounts received by the Distributor under
the Plan and any contingent deferred sales charges received by the Distributor
upon redemption of shares of the Fund. No other interest charge is included as
a distribution expense in the Distributor's calculation of its distribution
costs for this purpose. The broker's call rate is the interest rate charged to
securities brokers on loans secured by exchange-listed securities.


     The Fund is authorized to reimburse expenses incurred or to be incurred in
promoting the distribution of the Fund's Class A and Class C shares and in
servicing shareholder accounts. Reimbursement will be made through payments at
the end of each month. The amount of each monthly payment may in no event
exceed an amount equal to a payment at the annual rate of 0.25%, in the case of
Class A, and 0.70%, in the case of Class C, of the average net assets of the
respective Class during the month. No interest or other financing charges, if
any, incurred on any distribution expenses on behalf of Class A and Class C
will be reimbursable under the Plan. With respect to Class A, in the case of
all expenses other than expenses representing the service fee, and, with
respect to Class C, in the case of all expenses other than expenses
representing a gross sales credit or a residual to Financial Advisors


                                       21
<PAGE>

and other authorized financial representatives, such amounts shall be
determined at the beginning of each calendar quarter by the Trustees,
including, a majority of the Independent Trustees. Expenses representing the
service fee (for Class A) or a gross sales credit or a residual to Financial
Advisors and other authorized financial representatives (for Class C) may be
reimbursed without prior determination. In the event that the Distributor
proposes that monies shall be reimbursed for other than such expenses, then in
making quarterly determinations of the amounts that may be reimbursed by the
Fund, the Distributor will provide and the Trustees will review a quarterly
budget of projected distribution expenses to be incurred on behalf of the Fund,
together with a report explaining the purposes and anticipated benefits of
incurring such expenses. The Trustees will determine which particular expenses,
and the portions thereof, that may be borne by the Fund, and in making such a
determination shall consider the scope of the Distributor's commitment to
promoting the distribution of the Fund's Class A and Class C shares.


     Each Class paid 100% of the amounts accrued under the Plan with respect to
that Class for the fiscal year ended December 31, 1999 to the Distributor. The
Distributor and Dean Witter Reynolds estimate that they have spent, pursuant to
the Plan, $6,742,375 on behalf of Class B since the inception of the Plan. It
is estimated that this amount was spent in approximately the following ways:
(i) 14.64% ($987,346)-advertising and promotional expenses; (ii) 0.84%
($56,477)-printing of prospectuses for distribution to other than current
shareholders; and (iii) 84.52% ($5,698,552)-other expenses, including the gross
sales credit and the carrying charge, of which 1.47% ($83,916) represents
carrying charges, 22.95% ($1,307,909) represents commission credits to Dean
Witter Reynolds branch offices and other selected broker-dealers for payments
of commissions to Financial Advisors and other authorized financial
representatives, and 32.49% ($1,851,291) represents overhead and other branch
office distribution-related expenses. The amounts accrued by Class A and a
portion of the amounts accrued by Class C under the Plan during the fiscal year
ended December 31, 1999 were service fees. The remainder of the amounts accrued
by Class C were for expenses which relate to compensation of sales personnel
and associated overhead expenses.

     In the case of Class B shares, at any given time, the expenses of
distributing shares of the Fund may be more or less than the total of (i) the
payments made by the Fund pursuant to the Plan; and (ii) the proceeds of CDSCs
paid by investors upon redemption of shares. For example, if $1 million in
expenses in distributing Class B shares of the Fund had been incurred and
$750,000 had been received as described in (i) and (ii) above, the excess
expense would amount to $250,000. The Distributor has advised the Fund that in
the case of Class B shares the excess distribution expenses, including the
carrying charge designed to approximate the opportunity costs incurred by Dean
Witter Reynolds which arise from it having advanced monies without having
received the amount of any sales charges imposed at the time of sale of the
Fund's Class B shares, totaled $4,717,309 as of December 31, 1999 (the end of
the Fund's fiscal year), which was equal to 3.37% of the net assets of Class B
on such date. Of this amount, $2,455,436 represents excess distribution
expenses of Dean Witter National Municipal Trust the net assets of which were
combined with those of the Fund on November 7, 1997 pursuant to an Agreement
and Plan of Reorganization. Because there is no requirement under the Plan that
the Distributor be reimbursed for all distribution expenses with respect to
Class B shares or any requirement that the Plan be continued from year to year,
this excess amount does not constitute a liability of the Fund. Although there
is no legal obligation for the Fund to pay expenses incurred in excess of
payments made to the Distributor under the Plan and the proceeds of CDSCs paid
by investors upon redemption of shares, if for any reason the Plan is
terminated, the Trustees will consider at that time the manner in which to
treat such expenses. Any cumulative expenses incurred, but not yet recovered
through distribution fees or CDSCs, may or may not be recovered through future
distribution fees or CDSCs.


     In the case of Class A and Class C shares, expenses incurred pursuant to
the Plan in any calendar year in excess of 0.25% or 0.70% of the average daily
net assets of Class A or Class C, respectively, will not be reimbursed by the
Fund through payments in any subsequent year, except that expenses representing
a gross sales commission credited to Morgan Stanley Dean Witter Financial
Advisors and other authorized financial representatives at the time of sale may
be reimbursed in the subsequent calendar year. The Distributor has advised the
Fund that there were no such expenses that may be


                                       22

<PAGE>


reimbursed in the subsequent year in the case of Class A or Class C on December
31, 1999 (end of the calendar year). No interest or other financing charges
will be incurred on any Class A or Class C distribution expenses incurred by
the Distributor under the Plan or on any unreimbursed expenses due to the
Distributor pursuant to the Plan.


     No interested person of the Fund nor any Independent Trustee has any
direct financial interest in the operation of the Plan except to the extent
that the Distributor, the Investment Manager, Dean Witter Reynolds, MSDW
Services Company or certain of their employees may be deemed to have such an
interest as a result of benefits derived from the successful operation of the
Plan or as a result of receiving a portion of the amounts expended thereunder
by the Fund.

     On an annual basis, the Trustees, including a majority of the Independent
Trustees, consider whether the Plan should be continued. Prior to approving the
last continuation of the Plan, the Trustees requested and received from the
Distributor and reviewed all the information which they deemed necessary to
arrive at an informed determination. In making their determination to continue
the Plan, the Trustees considered: (1) the Fund's experience under the Plan and
whether such experience indicates that the Plan is operating as anticipated;
(2) the benefits the Fund had obtained, was obtaining and would be likely to
obtain under the Plan, including that: (a) the Plan is essential in order to
give Fund investors a choice of alternatives for payment of distribution and
service charges and to enable the Fund to continue to grow and avoid a pattern
of net redemptions which, in turn, are essential for effective investment
management; and (b) without the compensation to individual brokers and the
reimbursement of distribution and account maintenance expenses of Dean Witter
Reynolds's branch offices made possible by the 12b-1 fees, Dean Witter Reynolds
could not establish and maintain an effective system for distribution,
servicing of Fund shareholders and maintenance of shareholder accounts; and (3)
what services had been provided and were continuing to be provided under the
Plan to the Fund and its shareholders. Based upon their review, the Trustees,
including each of the Independent Trustees, determined that continuation of the
Plan would be in the best interest of the Fund and would have a reasonable
likelihood of continuing to benefit the Fund and its shareholders. In the
Trustees' quarterly review of the Plan, they will consider its continued
appropriateness and the level of compensation provided therein.

     The Plan may not be amended to increase materially the amount to be spent
for the services described therein without approval by the shareholders of the
affected Class or Classes of the Fund, and all material amendments to the Plan
must also be approved by the Trustees in the manner described above. The Plan
may be terminated at any time, without payment of any penalty, by vote of a
majority of the Independent Trustees or by a vote of a majority of the
outstanding voting securities of the Fund (as defined in the Investment Company
Act) on not more than thirty days' written notice to any other party to the
Plan. So long as the Plan is in effect, the election and nomination of
Independent Trustees shall be committed to the discretion of the Independent
Trustees.

VI. BROKERAGE ALLOCATION AND OTHER PRACTICES
- --------------------------------------------------------------------------------

A. BROKERAGE TRANSACTIONS


     Subject to the general supervision of the Board of Trustees, the
Investment Manager is responsible for decisions to buy and sell securities for
the Fund, the selection of brokers and dealers to effect the transactions, and
the negotiation of brokerage commissions, if any. Purchases and sales of
securities on a stock exchange are effected through brokers who charge a
commission for their services. The Fund expects that the primary market for the
securities in which it intends to invest will generally be the over-the-counter
market. In the over-the-counter market, securities are generally traded on a
"net" basis with dealers acting as principal for their own accounts without a
stated commission, although the price of the security usually includes a profit
to the dealer. The Fund expects that securities will be purchased at times in
underwritten offerings where the price includes a fixed amount of compensation,
generally referred to as the underwriter's concession or discount. Options and
futures transactions will usually be effected through a broker and a commission
will be charged. On occasion, the Fund may also purchase certain money market
instruments directly from an issuer, in which case no commissions or discounts
are paid.



     For the fiscal years ended December 31, 1997, 1998 and 1999, the Fund paid
no brokerage commissions.



B. COMMISSIONS


     Pursuant to an order of the SEC, the Fund may effect principal
transactions in certain money market instruments with Dean Witter Reynolds. The
Fund will limit its transactions with Dean Witter Reynolds to U.S. Government
and government agency securities, bank money instruments (i.e., certificates of
deposit and bankers' acceptances) and commercial paper. The transactions will
be effected with Dean Witter Reynolds only when the price available from Dean
Witter Reynolds is better than that available from other dealers.



     During the fiscal years ended December 31, 1997, 1998 and 1999, the Fund
did not effect any principal transactions with Dean Witter Reynolds.


     Brokerage transactions in securities listed on exchanges or admitted to
unlisted trading privileges may be effected through Dean Witter Reynolds,
Morgan Stanley & Co. and other affiliated brokers and dealers. In order for an
affiliated broker or dealer to effect any portfolio transactions on an exchange
for the Fund, the commissions, fees or other remuneration received by the
affiliated broker or dealer must be reasonable and fair compared to the
commissions, fees or other remuneration paid to other brokers in connection
with comparable transactions involving similar securities being purchased or
sold on an exchange during a comparable period of time. This standard would
allow the affiliated broker or dealer to receive no more than the remuneration
which would be expected to be received by an unaffiliated broker in a
commensurate arm's-length transaction. Furthermore, the Trustees, including the
Independent Trustees, have adopted procedures which are reasonably designed to
provide that any commissions, fees or other remuneration paid to an affiliated
broker or dealer are consistent with the foregoing



                                       24

<PAGE>

standard. The Fund does not reduce the management fee it pays to the Investment
Manager by any amount of the brokerage commissions it may pay to an affiliated
broker or dealer.


     During the fiscal years ended December 31, 1997, 1998 and 1999, the Fund
did not effect any securities transactions through any affiliated brokers or
dealers.



C. BROKERAGE SELECTION


     The policy of the Fund regarding purchases and sales of securities for its
portfolio is that primary consideration will be given to obtaining the most
favorable prices and efficient executions of transactions. Consistent with this
policy, when securities transactions are effected on a stock exchange, the
Fund's policy is to pay commissions which are considered fair and reasonable
without necessarily determining that the lowest possible commissions are paid
in all circumstances. The Fund believes that a requirement always to seek the
lowest possible commission cost could impede effective portfolio management and
preclude the Fund and the Investment Manager from obtaining a high quality of
brokerage and research services. In seeking to determine the reasonableness of
brokerage commissions paid in any transaction, the Investment Manager relies
upon its experience and knowledge regarding commissions generally charged by
various brokers and on its judgment in evaluating the brokerage and research
services received from the broker effecting the transaction. These
determinations are necessarily subjective and imprecise, as in most cases an
exact dollar value for those services is not ascertainable.


     In seeking to implement the Fund's policies, the Investment Manager
effects transactions with those brokers and dealers who the Investment Manager
believes provide the most favorable prices and are capable of providing
efficient executions. If the Investment Manager believes the prices and
executions are obtainable from more than one broker or dealer, it may give
consideration to placing portfolio transactions with those brokers and dealers
who also furnish research and other services to the Fund or the Investment
Manager. The services may include, but are not limited to, any one or more of
the following: information as to the availability of securities for purchase or
sale; statistical or factual information or opinions pertaining to investment;
wire services; and appraisals or evaluations of portfolio securities. The
information and services received by the Investment Manager from brokers and
dealers may be of benefit to the Investment Manager in the management of
accounts of some of its other clients and may not in all cases benefit the Fund
directly.

     The Investment Manager currently serves as investment manager to a number
of clients, including other investment companies, and may in the future act as
investment manager or advisor to others. It is the practice of the Investment
Manager to cause purchase and sale transactions to be allocated among the Fund
and others whose assets it manages in such manner as it deems equitable. In
making such allocations among the Fund and other client accounts, various
factors may be considered, including the respective investment objectives, the
relative size of portfolio holdings of the same or comparable securities, the
availability of cash for investment, the size of investment commitments
generally held and the opinions of the persons responsible for managing the
portfolios of the Fund and other client accounts. In the case of certain
initial and secondary public offerings, the Investment Manager utilizes a pro
rata allocation process based on the size of the Morgan Stanley Dean Witter
Funds involved and the number of shares available from the public offering.


D. DIRECTED BROKERAGE


     During the fiscal year ended December 31, 1999, the Fund did not pay any
brokerage commissions to brokers because of research services provided.



E. REGULAR BROKER-DEALERS


     During the fiscal year ended December 31, 1999, the Fund did not purchase
securities issued by brokers or dealers that were among the ten brokers or the
ten dealers that executed transactions for or with the Fund in the largest
dollar amounts during the year. As of December 31, 1999, the Fund did not own
any securities issued by any of such issuers.



                                       25
<PAGE>


VII. CAPITAL STOCK AND OTHER SECURITIES
- --------------------------------------------------------------------------------

     The shareholders of the Fund are entitled to a full vote for each full
share of beneficial interest held. The Fund is authorized to issue an unlimited
number of shares of beneficial interest. All shares of beneficial interest of
the Fund are of $0.01 par value and are equal as to earnings, assets and voting
privileges except that each Class will have exclusive voting privileges with
respect to matters relating to distribution expenses borne solely by such Class
or any other matter in which the interests of one Class differ from the
interests of any other Class. In addition, Class B shareholders will have the
right to vote on any proposed material increase in Class A's expenses, if such
proposal is submitted separately to Class A shareholders. Also, Class A, Class
B and Class C bear expenses related to the distribution of their respective
shares.

     The Fund's Declaration of Trust permits the Trustees to authorize the
creation of additional series of shares (the proceeds of which would be
invested in separate, independently managed portfolios) and additional Classes
of shares within any series. The Trustees have not presently authorized any
such additional series or Classes of shares other than as set forth in the
Prospectus.


     The Fund is not required to hold annual meetings of shareholders and in
ordinary circumstances the Fund does not intend to hold such meetings. The
Trustees may call special meetings of shareholders for action by shareholder
vote as may be required by the Investment Company Act or the Declaration of
Trust. Under certain circumstances, the Trustees may be removed by the actions
of the Trustees. In addition, under certain circumstances, the shareholders may
call a meeting to remove the Trustees and the Fund is required to provide
assistance in communicating with shareholders about such a meeting. The voting
rights of shareholders are not cumulative, so that holders of more than 50
percent of the shares voting can, if they choose, elect all Trustees being
selected, while the holders of the remaining shares would be unable to elect
any Trustees.


     Under Massachusetts law, shareholders of a business trust may, under
certain limited circumstances, be held personally liable as partners for the
obligations of the Fund. However, the Declaration of Trust contains an express
disclaimer of shareholder liability for acts or obligations of the Fund,
requires that notice of such Fund obligations include such disclaimer, and
provides for indemnification out of the Fund's property for any shareholder
held personally liable for the obligations of the Fund. Thus, the risk of a
shareholder incurring financial loss on account of shareholder liability is
limited to circumstances in which the Fund itself would be unable to meet its
obligations. Given the above limitations on shareholder personal liability, and
the nature of the Fund's assets and operations, the possibility of the Fund
being unable to meet its obligations is remote and thus, in the opinion of
Massachusetts counsel to the Fund, the risk to Fund shareholders of personal
liability is remote.


     All of the Trustees have been elected by the shareholders of the Fund,
most recently at a Special Meeting of Shareholders held on May 21, 1997. The
Trustees themselves have the power to alter the number and the terms of office
of the Trustees (as provided for in the Declaration of Trust), and they may at
any time lengthen or shorten their own terms or make their terms of unlimited
duration and appoint their own successors, provided that always at least a
majority of the Trustees has been elected by the shareholders of the Fund.


VIII. PURCHASE, REDEMPTION AND PRICING OF SHARES
- --------------------------------------------------------------------------------

A. PURCHASE/REDEMPTION OF SHARES


     Information concerning how Fund shares are offered to the public (and how
they are redeemed and exchanged) is provided in the Fund's Prospectus.


     In the case of Class B shares of the Fund issued in exchange for shares of
Dean Witter National Municipal Trust ("National Municipal") in connection with
the reorganization of National Municipal with the Fund on November 7, 1997
pursuant to an Agreement and Plan of Reorganization (the "Reorganization"),
that were subject to the lower CDSC schedule of National Municipal (as
described below), will continue to be subject to that lower CDSC schedule
unless (i) such shares are subsequently exchanged



                                       26

<PAGE>


for shares of a fund with a higher CDSC schedule or (ii) having been exchanged
for shares of Morgan Stanley Dean Witter North American Government Income
Trust, Morgan Stanley Dean Witter Global Short-Term Income Fund Inc. or Morgan
Stanley Dean Witter Short-Term U.S. Treasury Trust, Morgan Stanley Dean Witter
Limited Term Municipal Trust, Morgan Stanley Dean Witter Short-Term Bond Fund,
and the five Morgan Stanley Dean Witter funds which are money market funds (the
"Exchange Funds") are re-exchanged back into the Fund. Under such
circumstances, the CDSC schedule applicable to shares of the fund with the
higher CDSC schedule acquired in the exchange will apply to redemptions of such
fund's shares or, in the case of shares of any of the Exchange Funds acquired
in an exchange and then subsequently re-exchanged back into the Fund, the CDSC
schedule set forth in the above table will apply to redemptions of any of such
shares. The CDSC schedule applicable to National Municipal was as follows:
Shares held for three years or more after purchase (calculated as described in
the paragraph above) are not subject to any CDSC upon redemption. However,
shares redeemed earlier than three years after purchase may be subject to a
CDSC (calculated as described in the paragraph above), the percentage of which
depends on how long the shares have been held, as set forth in the following
table:





<TABLE>
<CAPTION>
           Year Since                                CDSC as a Percentage
     Purchase Payment Made                            of Amount Redeemed
- -------------------------------                     ---------------------

Third ........................................               1.0%
Fourth and thereafter ........................               None
</TABLE>

     Transfer Agent as Agent. With respect to the redemption or repurchase of
Fund shares, the application of proceeds to the purchase of new shares in the
Fund or any other Morgan Stanley Dean Witter Funds and the general
administration of the exchange privilege, the Transfer Agent acts as agent for
the Distributor and for the shareholder's authorized broker-dealer, if any, in
the performance of such functions. With respect to exchanges, redemptions or
repurchases, the Transfer Agent shall be liable for its own negligence and not
for the default or negligence of its correspondents or for losses in transit.
The Fund shall not be liable for any default or negligence of the Transfer
Agent, the Distributor or any authorized broker-dealer.


     The Distributor and any authorized broker-dealer have appointed the
Transfer Agent to act as their agent in connection with the application of
proceeds of any redemption of Fund shares to the purchase of shares of any
other Morgan Stanley Dean Witter Fund and the general administration of the
exchange privilege. No commission or discounts will be paid to the Distributor
or any authorized broker-dealer for any transaction pursuant to the exchange
privilege.


     Transfers of Shares. In the event a shareholder requests a transfer of
Fund shares to a new registration, the shares will be transferred without sales
charge at the time of transfer. With regard to the status of shares which are
either subject to the CDSC or free of such charge (and with regard to the
length of time shares subject to the charge have been held), any transfer
involving less than all of the shares in an account will be made on a pro rata
basis (that is, by transferring shares in the same proportion that the
transferred shares bear to the total shares in the account immediately prior to
the transfer). The transferred shares will continue to be subject to any
applicable CDSC as if they had not been so transferred.



B. Offering Price


     The Fund's Class B, Class C and Class D shares are offered at net asset
value per share and the Class A shares are offered at net asset value per share
plus any applicable FSC which is distributed


                                       27
<PAGE>

among the Fund's Distributor, Dean Witter Reynolds and other authorized dealers
as described in Section "V. Investment Management and Other Services - E. Rule
12b-1 Plan."

     The price of Fund shares, called "net asset value," is based on the value
of the Fund's portfolio securities. Net asset value per share of each Class is
calculated by dividing the value of the portion of the Fund's securities and
other assets attributable to that Class, less the liabilities attributable to
that Class, by the number of shares of that Class outstanding. The assets of
each Class of shares are invested in a single portfolio. The net asset value of
each Class, however, will differ because the Classes have different ongoing
fees.


     Portfolio securities (other than short-term debt securities and futures
and options) are valued for the Fund by an outside independent pricing service
approved by the Trustees. The pricing service has informed the Fund that in
valuing the portfolio securities for the Fund it uses both a computerized grid
matrix of tax-exempt securities and evaluations by its staff, in each case
based on information concerning market transactions and quotations from dealers
which reflect the bid side of the market each day. The portfolio securities for
the Fund are thus valued by reference to a combination of transactions and
quotations for the same or other securities believed to be comparable in
quality, coupon, maturity, type of issue, call provisions, trading
characteristics and other features deemed to be relevant. The Trustees believe
that timely and reliable market quotations are generally not readily available
to the Fund for purposes of valuing tax-exempt securities and that the
valuations supplied by the pricing service, using the procedures outlined above
and subject to periodic review, are more likely to approximate the fair value
of such securities. The Investment Manager will periodically review and
evaluate the procedures, methods and quality of services provided by the
pricing service then being used by the Fund and may, from time to time,
recommend to the Trustees the use of other pricing services or discontinuance
of the use of any pricing service in whole or part. The Trustees may determine
to approve such recommendation or take other provisions for pricing of the
portfolio securities for the Fund.


     Short-term taxable debt securities with remaining maturities of 60 days or
less at time of purchase are valued at amortized cost, unless the Trustees
determine such does not reflect the securities' market value, in which case
these securities will be valued at their fair value as determined by the
Trustees. Other taxable short-term debt securities with maturities of more than
60 days will be valued on a market to market basis until such time as they
reach a maturity of 60 days, whereupon they will be valued at amortized cost
using their value on the 61st day unless the Trustees determine such does not
reflect the securities' fair value, in which case these securities will be
valued at their fair market value as determined by the Trustees. Listed options
on debt securities are valued at the latest sale price on the exchange on which
they are listed unless no sales of such options have taken place that day, in
which case, they will be valued at the mean between their closing bid and asked
prices. Unlisted options on debt securities are valued at the mean between
their latest bid and asked price. Futures are valued at the latest sale price
on the commodities exchange on which they trade unless the Trustees determine
that such price does not reflect their market value, in which case they will be
valued at their fair value as determined in good faith under procedures
established by and under the supervision of the Trustees. All other securities
and other assets are valued at their fair value as determined in good faith
under procedures established by and under the supervision of the Trustees.


IX. TAXATION OF THE FUND AND SHAREHOLDERS
- --------------------------------------------------------------------------------

     The Fund generally will make three basic types of distributions: tax
exempt dividends, ordinary dividends and long-term capital gain distributions.
These types of distributions are reported differently on a shareholder's income
tax return and they are also subject to different rates of tax. The tax
treatment of the investment activities of the Fund will affect the amount and
timing and character of the distributions made by the Fund. Shareholders are
urged to consult their own tax professionals regarding specific questions as to
federal, state or local taxes.

     INVESTMENT COMPANY TAXATION. The Fund intends to remain qualified as a
regulated investment company under Subchapter M of the Internal Revenue Code of
1986. As such, the Fund will not be subject to federal income tax on its net
investment income and capital gains, if any, to the extent that it distributes
such income and capital gains to its shareholders.


                                       28

<PAGE>

     The Fund generally intends to distribute sufficient income and gains so
that the Fund will not pay corporate income tax on its earnings. The Fund also
generally intends to distribute to its shareholders in each calendar year a
sufficient amount of ordinary income and capital gains to avoid the imposition
of a 4% excise tax. However, the Fund may instead determine to retain all or
part of any ordinary income or capital gains in any year for reinvestment. In
such event, the Fund will pay federal income tax (and possibly excise tax) on
such retained gains.

     Gains or losses on sales of securities by the Fund will be long-term
capital gains or losses if the securities have a tax holding period of more
than one year. Gains or losses on the sale of securities with a tax holding
period of one year or less will be short-term gains or losses.

     In computing net investment income, the Fund will amortize any premiums
and original issue discounts on securities owned, if applicable. Capital gains
or losses realized upon sale or maturity of such securities will be based on
their amortized cost.

     All or a portion of any gain from tax-exempt obligations purchased at a
market discount may be treated as ordinary income rather than capital gain.

     From time to time, proposals have been introduced before Congress for the
purpose of restricting or eliminating the federal income tax exemption for
interest on municipal securities. Similar proposals may be introduced in the
future. If such a proposal were enacted, the availability of municipal
securities for investment by the Fund could be affected. In that event, the
Fund would re-evaluate its investment objective and policies.


     TAXATION OF DIVIDENDS AND DISTRIBUTIONS. The Fund intends to qualify to
pay "exempt-interest dividends" to its shareholders by maintaining, as of the
close of each quarter end of its taxable years, at least 50% of the value of its
assets in tax-exempt securities. An exempt-interest dividend is that part of the
dividend distributions made by the Fund which consists of interest received by
the Fund on tax-exempt securities upon which the shareholder incurs no federal
income taxes. Exempt-interest dividends are included, however, in determining
what portion, if any, of a person's Social Security benefits are subject to
federal income tax.


     The Fund intends to invest a portion of its assets in certain "private
activity bonds". As a result, a portion of the exempt-interest dividends paid
by the Fund will be an item of tax preference to shareholders subject to the
alternative minimum tax. Certain corporations which are subject to the
alternative minimum tax may also have to include exempt-interest dividends in
calculating their alternative minimum taxable income in situations where the
"adjusted current earnings" of the corporation exceeds its alternative minimum
taxable income.

     Shareholders will be subject to federal income tax on dividends paid from
interest income derived from taxable securities and on distributions of net
short-term capital gains. Such dividends and distributions are taxable to the
shareholder as ordinary dividend income regardless of whether the shareholder
receives such distributions in additional shares or in cash. Distributions of
long-term capital gains, if any, are taxable as long-term capital gains,
regardless of how long the shareholder has held the Fund shares and regardless
of whether the distribution is received in additional shares or in cash. Since
the income of the Fund is expected to be derived entirely from interest rather
than dividends, it is anticipated that no portion of such dividend
distributions will be eligible for the federal dividends received deduction
available to corporations.

     Shareholders are generally taxed on any ordinary dividend or capital gain
distributions from the Fund in the year they are actually distributed. However,
if any such dividends or distributions are declared in October, November or
December and paid in January then such amounts will be treated for tax purposes
as received by the shareholders on December 31, to shareholders of record of
such month.

     Shareholders who are not citizens or residents of the United States and
certain foreign entities may be subject to withholding of United States tax on
distributions made by the Fund of any taxable interest income and short term
capital gains.

     After the end of each calendar year, shareholders will be sent full
information on their dividends and capital gain distributions for tax purposes,
including the portion taxable as ordinary income, the portion taxable as
long-term capital gains and the percentage of any distributions which
constitute an item of tax preference for purposes of the alternative minimum
tax.


                                       29
<PAGE>


     PURCHASES AND REDEMPTIONS AND EXCHANGES OF FUND SHARES. Any dividend or
capital gains distribution received by a shareholder from the Fund will have
the effect of reducing the net asset value of the shareholder's stock in the
Fund by the exact amount of the dividend or capital gains distribution.
Furthermore, capital gains distributions and some portion of the dividends may
be subject to federal income taxes. If a shareholder of the Fund receives
exempt-interest dividends with respect to any share and if such share is held
by the shareholder for six months or less, then any loss on the sale or
exchange of such share may, to the extent of such exempt-interest dividends, be
disallowed. If the net asset value of the shares should be reduced below a
shareholder's cost as a result of the payment of dividends or the distribution
of realized long-term capital gains, such payment or distribution would be in
part a return of the shareholder's investment but nonetheless would be taxable
to the shareholder. Therefore, an investor should consider the tax implications
of purchasing shares of the Fund immediately prior to a distribution record
date.

     In general, a sale of shares results in capital gain or loss, and for
individual shareholders, is taxable at a federal rate dependent upon the length
of time the shares were held. A redemption of a shareholder's shares is
normally treated as a sale for tax purposes. Shares of the Fund held for a
period of one year or less will, for tax purposes, generally result in
short-term gains or losses and those held for more than one year generally
result in long-term gain or loss. Under current law, the maximum tax rate on
long-term capital gains realized by individual shareholders is 20%. Any loss
realized by shareholders upon a sale or redemption of shares within six months
of the date of their purchase will be treated as a long-term capital loss to
the extent of any distributions of net long-term capital gains with respect to
such shares during the six-month period.


     Gain or loss on the sale or redemption of shares in the Fund is measured
by the difference between the amount received and the tax basis of the shares.
Shareholders should keep records of investments made (including shares acquired
through reinvestment of dividends and distributions) so they can compute the
tax basis of their shares. Under certain circumstances a shareholder may
compute and use an average cost basis in determining the gain or loss on the
sale or redemption of shares.

     Exchanges of shares in the Fund for shares of other Morgan Stanley Dean
Witter Funds, are also subject to similar tax treatment. Such an exchange is
treated for tax purposes as a sale of the original shares in the Fund, followed
by the purchase of shares in the Fund.

     If a shareholder realizes a loss on the redemption or exchange of a shares
in the Fund and reinvests in shares of the Fund within 30 days before or after
the redemption or exchange, the transactions may be subject to the "wash sale"
rules, resulting in a postponement of the recognition of such loss for tax
purposes.


     Interest on indebtedness incurred by shareholders to purchase or carry
shares of the Fund is not deductible. Furthermore, entities or persons who are
"substantial users" (or related persons) of facilities financed by industrial
development bonds should consult their tax advisers before purchasing shares of
the Fund. "Substantial user" is defined generally by Treasury Regulation
Section 1.103-11(b) as including a "non-exempt person" who regularly uses in a
trade or business a part of a facility financed from the proceeds of industrial
development bonds.


X. UNDERWRITERS
- --------------------------------------------------------------------------------
     The Fund's shares are offered to the public on a continuous basis. The
Distributor, as the principal underwriter of the shares, has certain
obligations under the Distribution Agreement concerning the distribution of the
shares. These obligations and the compensation the Distributor receives are
described above in the sections titled "Principal Underwriter" and "Rule 12b-1
Plans."


XI. CALCULATION OF PERFORMANCE DATA
- --------------------------------------------------------------------------------
     From time to time the Fund may quote its "yield" and/or its "total return"
in advertisements and sales literature. These figures are computed separately
for Class A, Class B, Class C and Class D shares.

     Prior to July 28, 1997, the Fund offered only one Class of shares subject
to a maximum sales charge of 4.0% and no 12b-1 fee. Because the distribution
arrangement for Class A most closely resembles the


                                       30

<PAGE>


distribution arrangement applicable prior to the implementation of multiple
classes (i.e. Class A is sold with a front-end sales charge), historical
performance information has been restated to reflect (i) the actual maximum
sales charges applicable to Class A (i.e., 4.25%) and (ii) the ongoing 12b-1
fee applicable to Class A Shares. Furthermore, because all shares of the Fund
held prior to July 28, 1997 have been designated Class D shares, the Fund's
historical performance has also been restated to reflect the absence of any
sales charge in the case of Class D shares. Following the restated performance
information for Class A and Class D is the actual performance of the Fund based
on its original, single class sales charge structure as of its last fiscal
year. Also set forth below is the actual performance of Class B and Class C as
of their last fiscal year.

     Yield is calculated for any 30-day period as follows: the amount of
interest income for each security in the Fund's portfolio is determined in
accordance with regulatory requirements; the total for the entire portfolio
constitutes the Fund's gross income for the period. Expenses accrued during the
period are subtracted to arrive at "net investment income" of each Class. The
resulting amount is divided by the product of the maximum offering price per
share on the last day of the period, multiplied by the average number of shares
of the applicable Class outstanding during the period that were entitled to
dividends. This amount is added to 1 and raised to the sixth power. 1 is then
subtracted from the result and the difference is multiplied by 2 to arrive at
the annualized yield. For the 30-day period ended December 31, 1999, the yield,
calculated pursuant to the formula described above, was approximately 4.66%,
4.51%, 4.42% and 5.12% for Class A, Class B, Class C and Class D, respectively.


     The Fund may also quote a "tax-equivalent yield" for each Class determined
by dividing the tax-exempt portion of quoted yield by 1 minus the stated income
tax rate and adding the result to the portion of the yield that is not
tax-exempt. The yield for Class A, Class B, Class C and Class D shares, based
upon a Federal personal income tax bracket of 39.60% (the highest current
individual marginal tax rate), for the 30-day period ended December 31, 1999
were 7.72%, 7.47%, 7.32% and 8.48% respectively, based upon the yield quoted
above.

     The Fund's "average annual total return" represents an annualization of
the Fund's total return over a particular period and is computed by finding the
annual percentage rate which will result in the ending redeemable value of a
hypothetical $1,000 investment made at the beginning of a one, five or ten year
period, or for the period from the date of commencement of operations, if
shorter than any of the foregoing. The ending redeemable value is reduced by
any contingent deferred sales charge ("CDSC") at the end of the one, five, ten
year or other period. For the purpose of this calculation, it is assumed that
all dividends and distributions are reinvested. The formula for computing the
average annual total return involves a percentage obtained by dividing the
ending redeemable value by the amount of the initial investment (which in the
case of Class A shares is reduced by the Class A initial sales charge), taking
a root of the quotient (where the root is equivalent to the number of years in
the period) and subtracting 1 from the result. The average annual total returns
of the Class A and Class D shares of the Fund for the year ended December 31,
1999 were -6.95% and -2.71%, respectively; the restated average annual total
returns for the five years ended December 31, 1999 were 5.27% and 6.42%,
respectively; and the restated average annual total returns for the ten years
ended December, 1999 were 5.73% and 6.44%, respectively. The average annual
total returns of Class B for the fiscal year ended December 31, 1999 and for
the period July 28, 1997 (inception of the Class) through December 31, 1999
were -7.86% and 1.19%, respectively. The average annual total returns of Class
C for the fiscal year ended December 31, 1999 and for the period July 28, 1997
(inception of the Class) through December 31, 1999 were -4.29% and 2.09%,
respectively.

     In addition, the Fund may advertise its total return for each Class over
different periods of time by means of aggregate, average, year-by-year or other
types of total return figures. These calculations may or may not reflect the
imposition of the maximum front-end sales charge for Class A or the deduction
of the CDSC for each of Class B and Class C which, if reflected, would reduce
the performance quoted. For example, the average annual total return of the
Fund may be calculated in the manner described above, but without deduction for
any applicable sales charge. Based on the foregoing calculation, the Fund's
average annual total return for Class A shares for the year ended December 31,
1999 was -2.82% and the restated average annual total return for the five years
ended December 31, 1999 was 6.19% and the



                                       31
<PAGE>


restated average annual total return for the ten years ended December 31, 1999
was 6.19%. Because the Class D shares are not subject to any sales charge, the
Fund would only advertise average annual returns as calculated in the previous
paragraph. The average annual total returns of Class B for the fiscal year
ended December 31, 1999 and for the period July 28, 1997 through December 31,
1999 were -3.25% and 2.31%, respectively. The average annual total returns of
Class C for the fiscal year ended December 31, 1999 and for the period July 28,
1997 through December 31, 1999 were -3.37% and 2.09%, respectively.

     In addition, the Fund may compute its aggregate total return for each
Class for specified periods by determining the aggregate percentage rate which
will result in the ending value of a hypothetical $1,000 investment made at the
beginning of the period. For the purpose of this calculation, it is assumed
that all dividends and distributions are reinvested. The formula for computing
aggregate total return involves a percentage obtained by dividing the ending
value (without reduction for any sales charge) by the initial $1,000 investment
and subtracting 1 from the result. Based on the foregoing calculation, the
Fund's total returns for Class A and Class D shares for the year ended December
31, 1999 were -2.82% and -2.71%, respectively, the restated total returns for
the five years ended December 31, 1999 were 35.03% and 36.51%, and the restated
total returns for the ten years ended December 31, 1999 were 82.35% and 86.65%.
Based on the foregoing calculation, the Fund's total returns for Class B and
Class C shares for the year ended December 31, 1999 were -3.25% and -3.37%,
respectively, the total returns for the period July 28, 1997 through December
31, 1999 were 5.70% and 5.15%, respectively.

     The Fund may also advertise the growth of hypothetical investments of
$10,000, $50,000 and $100,000 in each Class of shares of the Fund by adding 1
to the Fund's aggregate total return to date (expressed as a decimal and
without taking into account the effect of any applicable CDSC) and multiplying
by $9,575, $48,250 and $97,250 in the case of Class A (investments of $10,000,
$50,000 and $100,000 adjusted for the initial sales charge) or by $10,000,
$50,000 and $100,000 in the case of each of Class B, Class C and Class D, as
the case may be. Investments of $10,000, $50,000 and $100,000 in each Class at
inception of the Class would have grown to the following amounts at December
31, 1999:

(1)   For purposes of restating the performance of Class A, the inception date
      set forth in the above table is the inception date of the Fund. However,
      Class A did not actually commence operation until July 28, 1997.



     All shares of the Fund held prior to July 28, 1997 were designated Class D
shares and accordingly, the actual performance numbers set forth below
represent the actual performance of the continuing Class D. The actual average
annual total returns of the Fund, calculated with the deduction of maximum
applicable sales charge described above, for the five years ended December 31,
1999 and for the ten years ended December 31, 1999 were 5.56% and 6.01%,
respectively. The actual average annual total returns of the Fund calculated
without the deduction for any applicable sales charge for the five years ended
December 31, 1999 and for the ten years ended December 31, 1999, were 6.42% and
6.44%, respectively. The Fund's actual aggregate total return, without the
deduction for any application sales charge for the five years ended December
31, 1999 was 36.51% and the actual total return for the ten years ended
December 31, 1999 was 86.65%. Investments of $10,000, $50,000 and $100,000,
adjusted for the sales charges in effect at such time (4.0%, 3.25% or 2.75%,
respectively), in the Fund at inception would have grown to $50,664, $255,299
and $513,237, respectively, at December 31, 1999.


     The Fund from time to time may also advertise its performance relative to
certain performance rankings and indexes compiled by recognized organizations.

Morgan Stanley Dean Witter Tax-Exempt Securities Trust
Notes to Financial Statements December 31, 1999


1. ORGANIZATION AND ACCOUNTING POLICIES

Morgan Stanley Dean Witter Tax-Exempt Securities Trust (the "Fund") is
registered under the Investment Company Act of 1940, as amended, as a
diversified, open-end management investment company. The Fund's investment
objective is to provide a high level of current income which is exempt from
federal income tax, consistent with the preservation of capital. The Fund was
incorporated in Maryland in 1979, commenced operations on March 27, 1980 and
reorganized as a Massachusetts business trust on April 30, 1987. On July 28,
1997, the Fund converted to a multiple class share structure.

The Fund offers Class A shares, Class B shares, Class C shares and Class D
shares. The four classes are substantially the same except that most Class A
shares are subject to a sales charge imposed at the time of purchase and some
Class A shares, and most Class B shares and Class C shares are subject to a
contingent deferred sales charge imposed on shares redeemed within one year,
six years and one year, respectively. Class D shares are not subject to a sales
charge. Additionally, Class A shares, Class B shares and Class C shares incur
distribution expenses.

The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts and disclosures. Actual results could differ
from those estimates.

The following is a summary of significant accounting policies:

A. VALUATION OF INVESTMENTS - Portfolio securities are valued for the Fund by
an outside independent pricing service approved by the Trustees. The pricing
service has informed the Fund that in valuing the Fund's portfolio securities,
it uses both a computerized matrix of tax-exempt securities and evaluations by
its staff, in each case based on information concerning market transactions and
quotations from dealers which reflect the bid side of the market each day. The
Fund's portfolio securities are thus valued by reference to a combination of
transactions and quotations for the same or other securities believed to be
comparable in quality, coupon, maturity, type of issue, call provisions,
trading characteristics and other features deemed to be relevant. Short-term
debt securities having a maturity date of more than sixty days at time of
purchase are valued on a mark-to-market basis until sixty days prior to
maturity and thereafter at amortized cost based on their value on the 61st day.
Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.

B. ACCOUNTING FOR INVESTMENTS - Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
The Fund amortizes premiums and accretes discounts over the life of the
respective securities. Interest income is accrued daily.

Morgan Stanley Dean Witter Tax-Exempt Securities Trust
Notes to Financial Statements December 31, 1999, continued


C. MULTIPLE CLASS ALLOCATIONS - Investment income, expenses (other than
distribution fees), and realized and unrealized gains and losses are allocated
to each class of shares based upon the relative net asset value on the date
such items are recognized. Distribution fees are charged directly to the
respective class.

D. FEDERAL INCOME TAX STATUS - It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable and nontaxable income to its
shareholders. Accordingly, no federal income tax provision is required.

E. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS - The Fund records dividends and
distributions to its shareholders on the record date. The amount of dividends
and distributions from net investment income and net realized capital gains are
determined in accordance with federal income tax regulations which may differ
from generally accepted accounting principles. These "book/tax" differences are
either considered temporary or permanent in nature. To the extent these
differences are permanent in nature, such amounts are reclassified within the
capital accounts based on their federal tax-basis treatment; temporary
differences do not require reclassification. Dividends and distributions which
exceed net investment income and net realized capital gains for financial
reporting purposes but not for tax purposes are reported as dividends in excess
of net investment income or distributions in excess of net realized capital
gains. To the extent they exceed net investment income and net realized capital
gains for tax purposes, they are reported as distributions of paid-in-capital.


2. INVESTMENT MANAGEMENT AGREEMENT

Pursuant to an Investment Management Agreement with Morgan Stanley Dean Witter
Advisors Inc. (the "Investment Manager"), the Fund pays the Investment Manager
a management fee, accrued daily and payable monthly, by applying the following
annual rates to the Fund's net assets determined as of the close of each
business day: 0.50% to the portion of daily net assets not exceeding $500
million; 0.425% to the portion of daily net assets exceeding $500 million but
not exceeding $750 million; 0.375% to the portion of daily net assets exceeding
$750 million but not exceeding $1 billion; 0.35% to the portion of daily net
assets exceeding $1 billion but not exceeding $1.25 billion; and 0.325% to the
portion of daily net assets exceeding $1.25 billion.

Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes, at its own expense, office space, facilities, equipment,
clerical, bookkeeping and certain legal services and pays the salaries of all
personnel, including officers of the Fund who are employees of the Investment
Manager. The Investment Manager also bears the cost of telephone services,
heat, light, power and other utilities provided to the Fund.

3. PLAN OF DISTRIBUTION

Shares of the Fund are distributed by Morgan Stanley Dean Witter Distributors
Inc. (the "Distributor"), an affiliate of the Investment Manager. The Fund has
adopted a Plan of Distribution (the "Plan"), pursuant to Rule 12b-1 under the
Act. The Plan provides that the Fund will pay the Distributor a fee which is
accrued daily and paid monthly at the following annual rates: (i) Class A - up
to 0.25% of the average daily net assets of Class A; (ii) Class B - 0.60% of
the average daily net assets of Class B; and (iii) Class C - up to 0.70% of the
average daily net assets of Class C. In the case of Class A shares, amounts
paid under the Plan are paid to the Distributor for services provided. In the
case of Class B and Class C shares, amounts paid under the Plan are paid to the
Distributor for (1) services provided and the expenses borne by it and others
in the distribution of the shares of these Classes, including the payment of
commissions for sales of these Classes and incentive compensation to, and
expenses of, Morgan Stanley Dean Witter Financial Advisors and others who
engage in or support distribution of the shares or who service shareholder
accounts, including overhead and telephone expenses; (2) printing and
distribution of prospectuses and reports used in connection with the offering
of these shares to other than current shareholders; and (3) preparation,
printing and distribution of sales literature and advertising materials. In
addition, the Distributor may utilize fees paid pursuant to the Plan, in the
case of Class B shares, to compensate Dean Witter Reynolds Inc. ("DWR"), an
affiliate of the Investment Manager and Distributor, and other selected
broker-dealers for their opportunity costs in advancing such amounts, which
compensation would be in the form of a carrying charge on any unreimbursed
expenses.

In the case of Class B shares, provided that the Plan continues in effect, any
cumulative expenses incurred by the Distributor but not yet recovered may be
recovered through the payment of future distribution fees from the Fund
pursuant to the Plan and contingent deferred sales charges paid by investors
upon redemption of Class B shares. Although there is no legal obligation for
the Fund to pay expenses incurred in excess of payments made to the Distributor
under the Plan and the proceeds of contingent deferred sales charges paid by
investors upon redemption of shares, if for any reason the Plan is terminated,
the Trustees will consider at that time the manner in which to treat such
expenses. The Distributor has advised the Fund that such excess amounts,
including carrying charges, totaled $4,717,309 at December 31, 1999.

In the case of Class A shares and Class C shares, expenses incurred pursuant to
the Plan in any calendar year in excess of 0.25% or 0.70% of the average daily
net assets of Class A or Class C, respectively, will not be reimbursed by the
Fund through payments in any subsequent year, except that expenses representing
a gross sales credit to Morgan Stanley Dean Witter Financial Advisors or other
selected

broker-dealer representatives may be reimbursed in the subsequent calendar
year. For the year ended December 31, 1999, the distribution fee was accrued
for Class A shares and Class C shares at the annual rate of 0.13% and 0.70%,
respectively.

The Distributor has informed the Fund that for the year ended December 31,
1999, it received contingent deferred sales charges from certain redemptions of
the Fund's Class B shares and Class C shares of $274,899 and $10,671,
respectively and received $107,818 in front-end sales charges from sales of the
Fund's Class A shares. The respective shareholders pay such charges which are
not an expense of the Fund.


4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES

The cost of purchases and proceeds from sales of portfolio securities,
excluding short-term investments, for the year ended December 31, 1999
aggregated $137,618,438 and $245,779,835, respectively.

Morgan Stanley Dean Witter Trust FSB, an affiliate of the Investment Manager
and Distributor, is the Fund's transfer agent. At December 31, 1999, the Fund
had transfer agent fees and expenses payable of approximately $13,800.

The Fund has an unfunded noncontributory defined benefit pension plan covering
all independent Trustees of the Fund who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on years of service and compensation during the last five years
of service. Aggregate pension costs for the year ended December 31, 1999
included in Trustees' fees and expenses in the Statement of Operations amounted
to $5,892. At December 31, 1999, the Fund had an accrued pension liability of
$52,664 which is included in accrued expenses in the Statement of Assets and
Liabilities.


5. FEDERAL INCOME TAX STATUS

At December 31, 1999, the Fund had a net capital loss carryover of
approximately $4,670,000 which will be available through December 31, 2007 to
offset future capital gains to the extent provided by regulations.

MORGAN STANLEY DEAN WITTER TAX-EXEMPT SECURITIES TRUST
REPORT OF INDEPENDENT ACCOUNTANTS


TO THE SHAREHOLDERS AND TRUSTEES
OF MORGAN STANLEY DEAN WITTER TAX-EXEMPT SECURITIES TRUST

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Morgan Stanley Dean Witter
Tax-Exempt Securities Trust (the "Fund") at December 31, 1999, the results of
its operations for the year then ended, the changes in its net assets for each
of the two years in the period then ended and the financial highlights for each
of the periods presented, in conformity with accounting principles generally
accepted in the United States. These financial statements and financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with auditing standards
generally accepted in the United States, which require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement
presentation. We believe that our audits, which included confirmation of
securities at December 31, 1999 by correspondence with the custodian, provide a
reasonable basis for the opinion expressed above.

RATINGS OF INVESTMENTS
- --------------------------------------------------------------------------------
MOODY'S INVESTORS SERVICE INC. ("MOODY'S")



                             MUNICIPAL BOND RATINGS



<TABLE>
<S>     <C>
Aaa     Bonds which are rated Aaa are judged to be of the best quality. They carry the smallest degree
        of investment risk and are generally referred to as "gilt edge." Interest payments are protected
        by a large or by an exceptionally stable margin and principal is secure. While the various
        protective elements are likely to change, such changes as can be visualized are most unlikely
        to impair the fundamentally strong position of such issues.

Aa      Bonds which are rated Aa are judged to be of high quality by all standards. Together with the Aaa
        group they comprise what are generally known as high grade bonds. They are rated lower than
        the best bonds because margins of protection may not be as large as in Aaa securities or
        fluctuation of protective elements may be of greater amplitude or there may be other elements
        present which make the long-term risks appear somewhat larger than in Aaa securities.
A       Bonds which are rated A possess many favorable investment attributes and are to be considered
        as upper medium grade obligations. Factors giving security to principal and interest are
        considered adequate, but elements may be present which suggest a susceptibility to impairment
        sometime in the future.

Baa     Bonds which are rated Baa are considered as medium grade obligations; i.e., they are neither
        highly protected nor poorly secured. Interest payments and principal security appear adequate
        for the present but certain protective elements may be lacking or may be characteristically
        unreliable over any great length of time. Such bonds lack outstanding investment characteristics
        and in fact have speculative characteristics as well.

        Bonds rated Aaa, Aa, A and Baa are considered investment grade bonds.

Ba      Bonds which are rated Ba are judged to have speculative elements; their future cannot be
        considered as well assured. Often the protection of interest and principal payments may be very
        moderate, and therefore not well safeguarded during both good and bad times in the future.
        Uncertainty of position characterizes bonds in this class.

B       Bonds which are rated B generally lack characteristics of a desirable investment. Assurance of
        interest and principal payments or of maintenance of other terms of the contract over any long
        period of time may be small.

Caa     Bonds which are rated Caa are of poor standing. Such issues may be in default or there may be
        present elements of danger with respect to principal or interest.

Ca      Bonds which are rated Ca present obligations which are speculative in a high degree. Such
        issues are often in default or have other marked shortcomings.

C       Bonds which are rated C are the lowest rated class of bonds, and issues so rated can be
        regarded as having extremely poor prospects of ever attaining any real investment standing.
</TABLE>

     Conditional Rating: Bonds for which the security depends upon the
completion of some act or the fulfillment of some condition are rated
conditionally. These bonds are secured by (a) earnings of projects under
construction, (b) earnings of projects unseasoned in operation experience, (c)
rentals which begin when facilities are completed or (d) payments to which some
other limiting condition attaches. Parenthetical rating denotes probable credit
stature upon completion of construction or elimination of basis of condition.


                                       54


<PAGE>

     Rating Refinements: Moody's may apply numerical modifiers, 1, 2, and 3 in
each generic rating classification from Aa through B in its municipal bond
rating system. The modifier 1 indicates that the security ranks in the higher
end of its generic rating category; the modifier 2 indicates a mid-range
ranking; and a modifier 3 indicates that the issue ranks in the lower end of
its generic rating category.


                            MUNICIPAL NOTE RATINGS

     Moody's ratings for state and municipal note and other short-term loans
are designated Moody's Investment Grade (MIG). MIG 1 denotes best quality and
means there is present strong protection for established cash flows, superior
liquidity support or demonstrated broad-based access to the market for
refinancing. MIG 2 denotes high quality and means that margins of protection
are ample although not as large as in MIG 1. MIG 3 denotes favorable quality
and means that all security elements are accounted for but that the undeniable
strength of the previous grades, MIG 1 and MIG 2, is lacking. MIG 4 denotes
adequate quality and means that the protection commonly regarded as required of
an investment security is present and that while the notes are not distinctly
or predominantly speculative, there is specific risk.


                       VARIABLE RATE DEMAND OBLIGATIONS

     A short-term rating, in addition to the Bond or MIG ratings, designated
VMIG may also be assigned to an issue having a demand feature. The assignment
of the VMIG symbol reflects such characteristics as payment upon periodic
demand rather than fixed maturity dates and payment relying on external
liquidity. The VMIG rating criteria are identical to the MIG criteria discussed
above.


                           COMMERCIAL PAPER RATINGS

     Moody's Commercial Paper ratings are opinions of the ability to repay
punctually promissory obligations not having an original maturity in excess of
nine months. These ratings apply to Municipal Commercial Paper as well as
taxable Commercial Paper. Moody's employs the following three designations, all
judged to be investment grade, to indicate the relative repayment capacity of
rated issuers: Prime-1, Prime-2, Prime-3.

     Issuers rated Prime-1 have a superior capacity for repayment of short-term
promissory obligations. Issuers rated Prime-2 have a strong capacity for
repayment of short-term promissory obligations; and Issuers rated Prime-3 have
an acceptable capacity for repayment of short-term promissory obligations.
Issuers rated Not Prime do not fall within any of the Prime rating categories.


STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S")


                            MUNICIPAL BOND RATINGS

     A Standard & Poor's municipal bond rating is a current assessment of the
creditworthiness of an obligor with respect to a specific obligation. This
assessment may take into consideration obligors such as guarantors, insurers or
lessees.

     The ratings are based on current information furnished by the issuer or
obtained by Standard & Poor's from other sources it considers reliable. The
ratings are based, in varying degrees, on the following considerations: (1)
likelihood of default-capacity and willingness of the obligor as to the timely
payment of interest and repayment of principal in accordance with the terms of
the obligation; (2) nature of and provisions of the obligation; and (3)
protection afforded by, and relative position of the obligation in the event of
bankruptcy, reorganization or other arrangement under the laws of bankruptcy
and other laws affecting creditors' rights.

     Standard & Poor's does not perform an audit in connection with any rating
and may, on occasion, rely on unaudited financial information. The ratings may
be changed, suspended or withdrawn as a result of changes in, or unavailability
of, such information, or for other reasons.


                                       55


<PAGE>


<TABLE>
<S>     <C>
AAA     Debt rated "AAA" has the highest rating assigned by Standard & Poor's. Capacity to pay interest
        and repay principal is extremely strong.

AA      Debt rated "AA" has a very strong capacity to pay interest and repay principal and differs from
        the highest-rated issues only in small degree.

A       Debt rated "A" has a strong capacity to pay interest and repay principal although they are
        somewhat more susceptible to the adverse effects of changes in circumstances and economic
        conditions than debt in higher-rated categories.

BBB     Debt rated "BBB" is regarded as having an adequate capacity to pay interest and repay
        principal. Whereas it normally exhibits adequate protection parameters, adverse economic
        conditions or changing circumstances are more likely to lead to a weakened capacity to pay
        interest and repay principal for debt in this category than for debt in higher-rated categories.
        Bonds rated AAA, AA, A and BBB are considered investment grade bonds.

BB      Debt rated "BB" has less near-term vulnerability to default than other speculative grade debt.
        However, it faces major ongoing uncertainties or exposure to adverse business, financial or
        economic conditions which would lead to inadequate capacity or willingness to pay interest and
        repay principal.

B       Debt rated "B" has a greater vulnerability to default but presently has the capacity to meet
        interest payments and principal repayments. Adverse business, financial or economic conditions
        would likely impair capacity or willingness to pay interest and repay principal.

CCC     Debt rated "CCC" has a current identifiable vulnerability to default, and is dependent upon
        favorable business, financial and economic conditions to meet timely payments of interest and
        repayments of principal. In the event of adverse business, financial or economic conditions, it is
        not likely to have the capacity to pay interest and repay principal.

CC      The rating "CC" is typically applied to debt subordinated to senior debt which is assigned an
        actual or implied "CCC" rating.

C       The rating "C" is typically applied to debt subordinated to senior debt which is assigned an actual
        or implied "CCC-" debt rating.

Cl      The rating "Cl" is reserved for income bonds on which no interest is being paid.

D       Debt rated "D" is in payment default. The `D' rating category is used when interest payments or
        principal payments are not made on the date due even if the applicable grace period has not
        expired, unless S&P believes that such payments will be made during such grace period. The
        `D' rating also will be used upon the filing of a bankruptcy petition if debt service payments are
        jeopardized.

NR      Indicates that no rating has been requested, that there is insufficient information on which to
        base a rating or that Standard & Poor's does not rate a particular type of obligation as a matter
        of policy.

        Bonds rated "BB", "B", "CCC", "CC" and "C" are regarded as having predominantly speculative
        characteristics with respect to capacity to pay interest and repay principal. "BB" indicates the
        least degree of speculation and "C" the highest degree of speculation. While such debt will likely
        have some quality and protective characteristics, these are outweighed by large uncertainties or
        major risk exposures to adverse conditions.

        Plus (+) or minus(-): The ratings from "AA" to "CCC" may be modified by the addition of a plus
        or minus sign to show relative standing within the major ratings categories.
</TABLE>

                                       56


<PAGE>



The foregoing ratings are sometimes followed by a "p" which indicates that the
rating is provisional. A provisional rating assumes the successful completion of
the project being financed by the bonds being rated and indicates that payment
of debt service requirements is largely or entirely dependent upon the
successful and timely completion of the project. This rating, however, while
addressing credit quality subsequent to completion of the project, makes no
comment on the likelihood or risk of default upon failure of such completion.


                            MUNICIPAL NOTE RATINGS

     Commencing on July 27, 1984, Standard & Poor's instituted a new rating
category with respect to certain municipal note issues with a maturity of less
than three years. The new note ratings denote the following:

     SP-1 denotes a very strong or strong capacity to pay principal and
   interest. Issues determined to possess overwhelming safety characteristics
   are given a plus (+) designation (SP-1+).

     SP-2 denotes a satisfactory capacity to pay principal and interest.

     SP-3 denotes a speculative capacity to pay principal and interest.


                           COMMERCIAL PAPER RATINGS

     Standard and Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more
than 365 days. The commercial paper rating is not a recommendation to purchase
or sell a security. The ratings are based upon current information furnished by
the issuer or obtained by S&P from other sources it considers reliable. The
ratings may be changed, suspended, or withdrawn as a result of changes in or
unavailability of such information. Ratings are graded into group categories,
ranging from "A" for the highest quality obligations to "D" for the lowest.
Ratings are applicable to both taxable and tax-exempt commercial paper. The
categories are as follows:

     Issues assigned A ratings are regarded as having the greatest capacity
   for timely payment. Issues in this category are further refined with the
   designation 1, 2 and 3 to indicate the relative degree of safety.

     A-1 indicates that the degree of safety regarding timely payments is
   very strong.

     A-2 indicates capacity for timely payment on issues with this designation
   is strong. However, the relative degree of safety is not as overwhelming as
   for issues designated "A-1".

     A-3 indicates a satisfactory capacity for timely payment. Obligations
   carrying this designation are, however, somewhat more vulnerable to the
   adverse effects of changes in circumstances than obligations carrying the
   higher designations.


FITCH IBCA, INC. ("FITCH")


                             MUNICIPAL BOND RATINGS

     Fitch investment grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The rating
represents Fitch's assessment of the issuer's ability to meet the obligations
of a specific debt issue or class of debt in a timely manner.

     The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the
issuer's future financial strength and credit quality.

     Fitch ratings do not reflect any credit enhancement that may be provided
by insurance policies or financial guarantees unless otherwise indicated.

     Bonds carrying the same rating are of similar but not necessarily
identical credit quality since the rating categories do not fully reflect small
differences in the degrees of credit risk.


                                       57


<PAGE>

     Fitch ratings are not recommendations to buy, sell, or hold any security.
Ratings do not comment on the adequacy of market price, the suitability of any
security for a particular investor, or the tax-exempt nature or taxability of
payments made in respect of any security.

     Fitch ratings are based on information obtained from issuers, other
obligors, underwriters, their experts, and other sources Fitch believes to be
reliable. Fitch does not audit or verify the truth or accuracy of such
information. Ratings may be changed, suspended, or withdrawn as a result of
changes in, or the unavailability of, information or for other reasons.

<TABLE>
<S>               <C>
AAA               Bonds considered to be investment grade and of the highest credit quality. The obligor
                  has an exceptionally strong ability to pay interest and repay principal, which is unlikely
                  to be affected by reasonably foreseeable events.

AA                Bonds considered to be investment grade and of very high credit quality. The obligor's
                  ability to pay interest and repay principal is very strong, although not quite as strong
                  as bonds rated "AAA." Because bonds rated in the "AAA" and "AA" categories are not
                  significantly vulnerable to foreseeable future developments, short-term debt of these
                  issuers is generally rated "F-1+."

A                 Bonds considered to be investment grade and of high credit quality. The obligor's
                  ability to pay interest and repay principal is considered to be strong, but may be more
                  vulnerable to adverse changes in economic conditions and circumstances than bonds
                  with higher ratings.

BBB               Bonds considered to be investment grade and of satisfactory credit quality. The
                  obligor's ability to pay interest and repay principal is considered to be adequate.
                  Adverse changes in economic conditions and circumstances, however, are more
                  likely to have adverse impact on these bonds, and therefore impair timely payment.
                  The likelihood that the ratings of these bonds will fall below investment grade is higher
                  than for bonds with higher ratings.

Plus (+) or       Plus and minus signs are used with a rating symbol to indicate the relative position of
Minus (-)         a credit within the rating category. Plus and minus signs, however, are not used in the
                  "AAA" category.

NR                Indicates that Fitch does not rate the specific issue.

Conditional       A conditional rating is premised on the successful completion of a project or the
                  occurrence of a specific event.

Suspended         A rating is suspended when Fitch deems the amount of information available from the
                  issuer to be inadequate for rating purposes.

Withdrawn         A rating will be withdrawn when an issue matures or is called or refinanced and, at
                  Fitch's discretion, when an issuer fails to furnish proper and timely information.

FitchAlert        Ratings are placed on FitchAlert to notify investors of an occurrence that is likely to
                  result in a rating change and the likely direction of such change. These are designated
                  as "Positive," indicating a potential upgrade, "Negative," for potential downgrade, or
                  "Evolving," where ratings may be raised or lowered. FitchAlert is relatively short-term,
                  and should be resolved within 12 months.

Ratings Outlook   An outlook is used to describe the most likely direction of any rating change over the
                  intermediate term. It is described as "Positive" or "Negative." The absence of a
                  designation indicates a stable outlook.
</TABLE>

     Speculative Grade Bond Ratings: Fitch speculative grade bond ratings
provide a guide to investors in determining the credit risk associated with a
particular security. The ratings ("BB" to "C") represent Fitch's assessment of
the likelihood of timely payment of principal and interest in accordance with
the terms of obligation for bond issues not in default. For defaulted bonds,
the rating ("DDD" to "D") is an assessment of the ultimate recovery value
through reorganization or liquidation.


                                       58


<PAGE>

     The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the
issuer's future financial strength.

     Bonds that have the rating are of similar but not necessarily identical
credit quality since rating categories cannot fully reflect the differences in
degrees of credit risk.


<TABLE>
<S>           <C>
BB            Bonds are considered speculative. The obligor's ability to pay interest and repay
              principal may be affected over time by adverse economic changes. However,
              business and financial alternatives can be identified which could assist the obligor in
              satisfying its debt service requirements.

B             Bonds are considered highly speculative. While bonds in this class are currently
              meeting debt service requirements, the probability of continued timely payment of
              principal and interest reflects the obligor's limited margin of safety and the need for
              reasonable business and economic activity throughout the life of the issue.

CCC           Bonds have certain identifiable characteristics which, if not remedied, may lead to
              default. The ability to meet obligations requires an advantageous business and
              economic environment.

CC            Bonds are minimally protected. Default in payment of interest and/or principal seems
              probable over time.

C             Bonds are in imminent default in payment of interest or principal.

DDD           Bonds are in default on interest and/or principal payments. Such bonds are extremely
DD and D      speculative and should be valued on the basis of their ultimate recovery value in
              liquidation or reorganization of the obligor. "DDD" represents the highest potential for
              recovery on these bonds, and "D" represents the lowest potential for recovery

Plus (+) or   Plus and minus signs are used with a rating symbol to indicate the relative position
Minus (-)     of a credit within the rating category. Plus and minus signs, however, are not used in
              the "DDD," "DD," or "D" categories.
</TABLE>

                               SHORT-TERM RATINGS

     Fitch's short-term ratings apply to debt obligations that are payable on
demand or have original maturities of up to three years, including commercial
paper, certificates of deposit, medium-term notes, and municipal and investment
notes.

     The short-term rating places greater emphasis than a long-term rating on
the existence of liquidity necessary to meet the issuer's obligations in a
timely manner.

     Fitch short-term ratings are as follows:


<TABLE>
<S>           <C>
F-1+          Exceptionally Strong Credit Quality. Issues assigned this rating are regarded as
              having the strongest degree of assurance for timely payment.

F-1           Very Strong Credit Quality. Issues assigned this rating reflect an assurance of timely
              payment only slightly less in degree than issues rated "F-1+."

F-2           Good Credit Quality. Issues assigned this rating have a satisfactory degree of
              assurance for timely payment, but the margin of safety is not as great as for issues
              assigned "F-1+" and "F-1" ratings.

F-3           Fair Credit Quality. Issues assigned this rating have characteristics suggesting that
              the degree of assurance for timely payment is adequate; however, near-term adverse
              changes could cause these securities to be rated below investment grade.

F-S           Weak Credit Quality. Issues assigned this rating have characteristics suggesting a

              adverse changes in financial and economic conditions.

D             Default. Issues assigned this rating are in actual or imminent payment default.

LOC           The symbol "LOC" indicates that the rating is based on a letter of credit issued by a
              commercial bank.

I. FUND HISTORY
- --------------------------------------------------------------------------------


     The Fund was organized as a Massachusetts business trust under the laws of
the Commonwealth of Massachusetts on October 29, 1990, with the name Dean
Witter Multi-State Municipal Series Trust. Effective June 22, 1998, the Fund's
name was changed to Morgan Stanley Dean Witter Multi-State Municipal Series
Trust.


II. DESCRIPTION OF THE FUND AND THE INVESTMENTS AND RISKS OF THE SERIES
- --------------------------------------------------------------------------------

A. CLASSIFICATION

     The Fund is an open-end, non-diversified management investment company.
The Fund consists of 10 separate fund portfolios referred to as "Series:" the
Arizona Series, the California Series, the Florida Series, the Massachusetts
Series, the Michigan Series, the Minnesota Series, the New Jersey Series, the
New York Series, the Ohio Series and the Pennsylvania Series. The investment
objective of each Series is to provide a high a level of current income exempt
from both federal and the designated state income tax, consistent with the
preservation of capital.


     The Fund is a "non-diversified" mutual fund and, as such, its investments
are not required to meet certain diversification requirements under federal
securities law. Compared with "diversified" funds, the Fund may invest a
greater percentage of its assets in the securities of an individual corporation
or governmental entity. Thus, the Fund's assets may be concentrated in fewer
securities than other funds. A decline in the value of those investments would
cause the Fund's overall value to decline to a greater degree. The Fund's
investments (with the exception of the Massachusetts Series and the Minnesota
Series), however, are currently diversified and may remain diversified in the
future.


B. INVESTMENT STRATEGIES AND RISKS

     The following discussion of the Series' investment strategies and risks
should be read with the sections of the Fund's Prospectus titled "Principal
Investment Strategies," "Principal Risks," "Additional Investment Strategy
Information," and "Additional Risk Information."


     TAXABLE SECURITIES. Each Series may invest up to 20% of its total assets
in taxable money market instruments, tax-exempt securities of other states and
municipalities and futures and options. Investments in taxable money market
instruments would generally be made under any one of the following
circumstances: (a) pending investment of proceeds of the sale of each Series'
shares or of portfolio securities, (b) pending settlement of purchases of
portfolio securities and (c) to maintain liquidity for the purpose of meeting
anticipated redemptions. Only those tax-exempt securities of other states which
satisfy the standards established for the tax-exempt securities of a
Series may be purchased by that Series.


     The types of taxable money market instruments in which each Series may
invest are limited to the following short-term fixed-income securities
(maturing in one year or less from the time of purchase): (i) obligations of
the United States Government, its agencies, instrumentalities or authorities;
(ii)  commercial paper rated P-1 by Moody's Investors Services, Inc.
("Moody's") or A-1 by Standard & Poor's Corporation ("S&P"); (iii) certificates
of deposit of domestic banks with assets of $1 billion or more; and (iv)
repurchase agreements with respect to portfolio securities.

     VARIABLE RATE AND FLOATING RATE OBLIGATIONS. Each Series may invest in
Municipal Bonds and Municipal Notes ("Municipal Obligations") of the type
called variable rate. The interest rate payable on a variable rate obligation
is adjusted either at predesignated periodic intervals or whenever there is a
change in the market rate of interest on which the interest rate payable is
based. Other features may include the right whereby a Series may demand
prepayment of the principal amount of the obligation prior to its stated
maturity (a "demand feature") and the right of the issuer to prepay the
principal amount prior to maturity. The principal benefit of a variable rate
obligation is that the interest rate adjustment


                                       4
<PAGE>

minimizes changes in the market value of the obligation. The principal benefit
to a Series of purchasing obligations with a demand feature is that liquidity,
and the ability of the Series to obtain repayment of the full principal amount
of an obligation prior to maturity, is enhanced.

     INDUSTRIAL DEVELOPMENT AND POLLUTION CONTROL REVENUE BONDS. Each Series
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
such bonds are in the same industry. In cases where such users are in the same
industry, there may be additional risk in the event of an economic downturn in
such industry, which may result generally in a lowered need for such facilities
and a lowered ability of such users to pay for the use of such facilities.

     LENDING OF PORTFOLIO SECURITIES. Each Series may lend portfolio securities
to brokers, dealers and financial institutions provided that cash equal to at
least 100% of the market value of the securities loaned is deposited by the
borrower with the Series and is maintained each business day in a segregated
account pursuant to applicable regulations. The collateral value of the loaned
securities will be marked-to-market daily. While such securities are on loan,
the borrower will pay the Series any income accruing thereon, and the Series
may invest the cash collateral in portfolio securities, thereby earning
additional income. Each Series will not lend more than 25% of the value of the
total assets of any Series. Loans will be subject to termination by a Series in
the normal settlement time, currently five business days after notice, or by
the borrower on one day's notice. Borrowed securities must be returned when the
loan is terminated. Any gain or loss in the market price of the borrowed
securities which occurs during the term of the loan inures to a Series and its
shareholders. A Series may pay reasonable finders, borrowers, administrative,
and custodial fees in connection with a loan. The creditworthiness of firms to
which a Series lends its portfolio securities will be monitored on an ongoing
basis.

     FUTURES CONTRACTS AND OPTIONS ON FUTURES. Each Series may invest in
financial futures contracts ("futures contracts") and related options thereon.
These futures contracts and related options thereon will be used only as a
hedge against anticipated interest rate changes. A futures contract sale
creates an obligation by a Series, as seller, to deliver the specific type of
instrument called for in the contract at a specified future time for a
specified price. A futures contract purchase would create an obligation by the
Series, as purchaser, to take delivery of the specific type of financial
instrument at a specified future time at a specified price. The specific
securities delivered or taken, respectively, at settlement date, would not be
determined until on or near that date. The determination would be in accordance
with the rules of the exchange on which the futures contract sale or purchase
was effected.

     Although the terms of futures contracts specify actual delivery or receipt
of securities, in most instances the contracts are closed out before the
settlement date without the making or taking of delivery of the securities.
Closing out of a futures contract is usually effected by entering into an
offsetting transaction. An offsetting transaction for a futures contract sale
is effected by a Series entering into a futures contract purchase for the same
aggregate amount of the specific type of financial instrument at the same
delivery date. If the price in the sale exceeds the price in the offsetting
purchase, the Series is immediately paid the difference and thus realizes a
gain. If the offsetting purchase price exceeds the sale price, the Series pays
the difference and realizes a loss. Similarly, the closing out of a futures
contract purchase is effected by a Series entering into a futures contract
sale. If the offsetting sale price exceeds the purchase price the Series
realizes a gain, and if the offsetting sale price is less than the purchase
price the Series realizes a loss.

     Unlike a futures contract, which requires the parties to buy and sell a
security on a set date, an option on a futures contract entitles its holder to
decide on or before a future date whether to enter into such a contract (a long
position in the case of a call option and a short position in the case of a put
option). If the holder decides not to enter into the contract, the premium paid
for the contract is lost. Since the value of the option is fixed at the point
of sale, there are no daily payments of cash to reflect the change in the value
of the underlying contract, as discussed below for futures contracts. The value
of the option changes is reflected in the net asset value of the particular
Series holding the options.

     Each Series is required to maintain margin deposits with brokerage firms
through which it effects futures contracts and options thereon. The initial
margin requirements vary according to the type of the


                                       5
<PAGE>

underlying security. In addition, due to current industry practice, daily
variations in gains and losses on open contracts are required to be reflected
in cash in the form of variation margin payments. A Series may be required to
make additional margin payments during the term of the contract.

     Currently, futures contracts can be purchased on debt securities such as
U.S. Treasury Bills and Bonds, U.S. Treasury Notes with maturities between 6
1/2 and 10 years, Certificates of the Government National Mortgage Association,
Bank Certificates of Deposit and on a municipal bond index. Each Series may
invest in interest rate futures contracts covering these types of financial
instruments as well as in new types of contracts that become available in the
future.

     Financial futures contracts are traded in an auction environment on the
floors of several Exchanges--principally, the Chicago Board of Trade, the
Chicago Mercantile Exchange and the New York Futures Exchange. Each Exchange
guarantees performance under contract provisions through a clearing
corporation, a nonprofit organization managed by the Exchange membership which
is also responsible for handling daily accounting of deposits or withdrawals of
margin. A risk in employing futures contracts to protect against the price
volatility of portfolio securities is that the prices of securities subject to
futures contracts may correlate imperfectly with the behavior of the cash
prices of each Series portfolio securities. The correlation may be distorted by
the fact that the futures market is dominated by short-term traders seeking to
profit from the difference between a contract or security price objective and
their cost of borrowed funds. This would reduce the value of futures contracts
for hedging purposes over a short time period. The correlation may be further
distorted since the futures contracts that are being used to hedge are not
based on municipal obligations.

     Another risk is that a Series' Investment Manager could be incorrect in
its expectations as to the direction or extent of various interest rate
movements or the time span within which the movements take place. For example,
if a Series sold futures contracts for the sale of securities in anticipation
of an increase in interest rates, and then interest rates went down instead,
causing bond prices to rise, that Series would lose money on the sale. Put and
call options on financial futures have characteristics similar to Exchange
traded options.

     In addition to the risks associated in investing in options on securities,
there are particular risks associated with investing in options on futures. In
particular, the ability to establish and close out positions on such options
will be subject to the development and maintenance of a liquid secondary
market. It is not certain that such a market will develop.

     A Series may not enter into futures contracts or related options thereon
if, immediately thereafter, the amount committed to margin plus the amount paid
for option premiums exceeds 5% of the value of that Series' total assets. In
instances involving the purchase of futures contracts by a Series, an amount
equal to the market value of the futures contract will be deposited in a
segregated account of cash and cash equivalents or other liquid portfolio
securities to collateralize the position and thereby ensure that the use of
such futures is unleveraged. A Series may not purchase or sell futures
contracts or related options if, immediately thereafter, more than one-third of
the net assets of that Series would be hedged.

     Municipal Bond Index Futures. Each Series may utilize municipal bond index
futures contracts for hedging purposes. The strategies in employing such
contracts will be similar to that discussed above with respect to financial
futures and options thereon. A municipal bond index is a method of reflecting
in a single number the market value of many different municipal bonds and is
designed to be representative of the municipal bond market generally. The index
fluctuates in response to changes in the market values of the bonds included
within the index. Unlike futures contracts on particular financial instruments,
transactions in futures on a municipal bond index will be settled in cash, if
held until the close of trading in the contract. However, like any other
futures contract, a position in the contract may be closed out by a purchase or
sale of an offsetting contract for the same delivery month prior to expiration
of the contract.

     Options. Each Series may purchase or sell (write) options on debt
securities as a means of achieving additional return or hedging the value of a
Series' portfolio. A Series will only buy options listed on national securities
exchanges. A Series will not purchase options if, as a result, the aggregate
cost of all outstanding options exceeds 10% of the Series total assets.


                                       6
<PAGE>

     Presently there are no options on tax-exempt securities traded on national
securities exchanges. Each Series will not invest in options on debt securities
in the coming year or until such time as they become available on national
securities exchanges.

     A call option is a contract that gives the holder of the option the right
to buy from the writer of the call option, in return for a premium, the
security underlying the option at a specified exercise price at any time during
the term of the option. The writer of the call option has the obligation, upon
exercise of the option, to deliver the underlying security upon payment of the
exercise price during the option period. A put option is a contract that gives
the holder of the option the right to sell to the writer, in return for a
premium, the underlying security at a specified price during the term of the
option. The writer of the put has the obligation to buy the underlying security
upon exercise, at the exercise price during the option period.

     A Series will only write covered call or covered put options listed on
national exchanges. A Series may not write covered options in an amount
exceeding 20% of the value of the total assets of that Series. A call option is
"covered" if a Series owns the underlying security covered by the call or has
an absolute and immediate right to acquire that security or futures contract
without additional cash consideration (or for additional cash consideration
held in a segregated account by its custodian) upon conversion or exchange of
other securities held in its portfolio. A call option is also covered if a
Series holds a call on the same security or futures contract as the call
written, where the exercise price of the call held is (i) equal to or less than
the exercise price of the call written or (ii) greater than the exercise price
of the call written if the difference is maintained by a Series in cash,
Treasury bills or other liquid portfolio securities in a segregated account
with its custodian. A put option is "covered" if a Series maintains cash,
Treasury bills or other liquid portfolio securities with a value equal to the
exercise price in a segregated account with its custodian, or else holds a put
on the same security or futures contract as the put written where the exercise
price of the put held is equal to or greater than the exercise price of the put
written.

     If a Series has written an option, it may terminate its obligation by
effecting a closing purchase transaction. This is accomplished by purchasing an
option of the same series as the option previously written. However, once the
Series has been assigned an exercise notice, the Series will be unable to
effect a closing purchase transaction. Similarly, if the Series is the holder
of an option, it may liquidate its position by effecting a closing sale
transaction. This is accomplished by selling an option of the same series as
the option previously purchased. There can be no assurance that either a
closing purchase or sale transaction on behalf of a Series can be effected when
the Series so desires.

     A Series will realize a profit from a closing transaction if the price of
the transaction is less than the premium received from writing the option or is
more than the premium paid to purchase the option; a Series will realize a loss
from a closing transaction if the price of the transaction is more than the
premium received from writing the option or is less than the premium paid to
purchase the option. Since call option prices generally reflect increases in
the price of the underlying security, any loss resulting from the purchase of a
call option may also be wholly or partially offset by unrealized appreciation
of the underlying security. If a put option written by a Series is exercised,
the Series may incur a loss equal to the difference between the exercise price
of the option and the sum of the sale price of the underlying security plus the
premiums received from the sale of the option. Other principal factors
affecting the market value of a put or a call option include supply and demand,
interest rates, the current market price and price volatility of the underlying
security and the time remaining until the expiration date.

     An option position may be closed out only on an exchange which provides a
secondary market for an option of the same series. Although a Series will
generally purchase or write only those options for which there appears to be an
active secondary market, there is no assurance that a liquid secondary market
on an exchange will exist for any particular option. In such event, it might
not be possible to effect closing transactions in particular options, so that
the Series would have to exercise its options in order to realize any profit
and would incur brokerage commissions upon the exercise of call options and
upon the subsequent disposition of underlying securities for the exercise of
put options. If a Series as a covered call option writer is unable to effect a
closing purchase transaction in a secondary market, it will not be able to sell
the underlying security until the option expires or it delivers the underlying
security upon exercise.

     REPURCHASE AGREEMENTS. Each Series may invest in repurchase agreements.
When cash may be available for only a few days, it may be invested by the
Series in repurchase agreements until such time as it may otherwise be invested
or used for payments of obligations. These agreements, which may be viewed as a
type of secured lending by the Series, typically involve the acquisition by a
Series of debt securities from a selling financial institution such as a bank,
savings and loan association or broker-dealer. The agreement provides that the
Series sell back to the institution, and that the institution will repurchase,
the underlying security serving as collateral at a specified price and at a
fixed time in the future, usually not more than seven days from the date of
purchase. The collateral will be marked-to-market daily to determine that the
value of the collateral, as specified in the agreement, does not decrease below
the purchase price plus accrued interest. If such decrease occurs, additional
collateral will be requested and, when received, added to the account to
maintain full collateralization. The Series will accrue interest from the
institution until the time when the repurchase is to occur. Although this date
is deemed by a Series to be the maturity date of a repurchase agreement, the
maturities of securities subject to repurchase agreements are not subject to
any limits.

     While repurchase agreements involve certain risks not associated with
direct investments in debt securities, each Series follows procedures designed
to minimize such risks. These procedures include effecting repurchase
transactions only with large, well-capitalized and well-established financial
institutions whose financial condition will be continually monitored by the
Investment Manager subject to procedures established by the Trustees. In
addition, as described above, the value of the collateral underlying the
repurchase agreement will be at least equal to the repurchase price, including
any accrued interest earned on the repurchase agreement. In the event of a
default or bankruptcy by a selling financial institution, a Series will seek to
liquidate such collateral. However, the exercising of the Series' right to
liquidate such collateral could involve certain costs or delays and, to the
extent that proceeds from any sale upon a default of the obligation to
repurchase were less than the repurchase price, the Series could suffer a loss.
It is the current policy of each Series not to invest in repurchase agreements
that do not mature within seven days if any such investment, together with any
other illiquid asset held by that Series, amount to more than 10% of the total
assets of that Series.

     WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. Each Series may purchase
tax-exempt securities on a when-issued or delayed delivery basis. When these
transactions are negotiated, the price is fixed at the time of the commitment,
but delivery and payment can take place a month or more after the date of
commitment. While a Series will only purchase securities on a when-issued,
delayed delivery with the intention of acquiring the securities, the Series may
sell the securities before the settlement date, if it is deemed advisable. The
securities so purchased or sold are subject to market fluctuation and no
interest or dividends accrue to the purchaser prior to the settlement date.

     At the time a Series makes the commitment to purchase or sell securities
on a when-issued, delayed delivery, it will record the transaction and
thereafter reflect the value, each day, of such security purchased, or if a
sale, the proceeds to be received, in determining its net asset value. At the
time of delivery of the securities, their value may be more or less than the
purchase or sale price. An increase in the percentage of a Series' assets
committed to the purchase of securities on a when-issued, delayed delivery may
increase the volatility of its net asset value. Each Series will also establish
a segregated account with its custodian bank in which it will continually
maintain cash or cash equivalents or other liquid portfolio securities equal in
value to commitments to purchase securities on a when-issued or delayed
delivery basis.


     YEAR 2000. The investment management services provided to the Fund and
each Series by the Investment Manager and the services provided to shareholders
by the Distributor and the Transfer Agent depend on the smooth functioning of
their computer systems. Many computer software systems in use today were
designed in such a way that they may not be able to recognize the year 2000,
but revert to 1900 or some other date, due to the manner in which dates were
encoded and calculated. That failure could have a negative impact on the
handling of securities trades, pricing and account services.

     In addition, it is possible that the markets for securities in which a
Series invests may have been detrimentally affected by computer failures
throughout the financial services industry beginning


                                       8
<PAGE>


January 1, 2000. Improperly functioning trading systems may result in
settlement problems and liquidity issues. Corporate and governmental data
processing errors could result in production problems for individual issuers
and overall economic uncertainties. Operations ran smoothly from the last week
in December through the first few weeks of January, but the year 2000 issue may
yet have an adverse impact on financial market participants and other entities,
including the issuers whose securities are contained in each Series' portfolio.


     THE ARIZONA SERIES -- SPECIAL INVESTMENT CONSIDERATIONS. The Arizona
Series will invest principally in securities of political subdivisions and
other issuers of the State of Arizona the interest on which is exempt from
federal and Arizona income taxes. As a result, the ability of such Arizona
issuers to meet their obligations with respect to such securities generally
will be influenced by the political, economic and regulatory developments
affecting the state of Arizona and the particular revenue streams supporting
such issuers' obligations. If any of such political subdivisions are unable to
meet their financial obligations, the income derived by the Arizona Series, the
ability to preserve or realize appreciation of the Arizona Series' capital, and
the liquidity of the Arizona Series could be adversely affected. The following
summary respecting the State of Arizona is only general in nature and does not
purport to be a description of the investment considerations and factors which
may have an effect on the obligations of a particular issuer in which the
Arizona Series may invest.


     Arizona's economy continues on a path of strong growth, although
economists at Arizona State University expect the growth rate to slow. There
are, however, no signs of any serious imbalances. Arizona's economy is among
the fastest growing in the country. The state's population increased by more
than 100,000 each year during the 8-year period from 1991 to 1999. During 1999,
Arizona's population was estimated at approximately 4.8 million. As a result,
homebuilding and commercial construction are extremely strong, although
construction is expected to slow somewhat in 2000. This growth in population
will require corresponding increases in revenue of Arizona issuers to meet
increased demands for infrastructure development and various services, and the
performance of Arizona's economy will be critical to providing such increased
revenue.

     The state's principal economic sectors include services, construction,
manufacturing dominated by electrical, transportation and military equipment,
high technology, government, tourism and the military. State unemployment rates
have remained generally comparable to the national average in recent years,
while the Arizona economy has generally performed above the national average in
recent years. Arizona has held a steady position among the top five states in
employment growth since May 1993. In 1998, the Arizona rate of non-agricultural
job creation ranked first in the nation and is projected to be in excess of 4%
in 1999 by economists at the University of Arizona. Furthermore, in 1999,
Arizona's personal income increased by an estimated 7.5 percent.


     Arizona is required by law to maintain a balanced budget. To achieve this
objective, Arizona has, in the past, utilized a combination of spending
reductions and tax increases. The condition of the national economy will
continue to be a significant factor influencing Arizona's budget during the
upcoming fiscal year.

     Arizona's constitution limits the amount of debt payable from general tax
revenues that may be contracted by the State to $350,000. However, certain
other issuers have the statutory power to issue obligations payable from other
sources of revenue which affect the whole or large portions of the State. For
example, the Transportation Board of the State of Arizona Department of
Transportation may issue obligations for highways which are paid from revenues
generated from, among other sources, gasoline taxes.


     Arizona's constitution also restricts debt payable from general tax
revenue of certain other issuers of the State. Most importantly, no county,
city, town, school district, or other municipal corporation of the State may
for any purpose become indebted in any manner in an amount exceeding 6% of the
taxable property in such county, city, town, school district, or other
municipal corporation without the assent of a majority of the qualified
electors thereof voting at an election provided by law to be held for that
purpose; provided, however, that (i) under no circumstances may any county or
school district of the State become indebted in an amount exceeding 15% (or 30%
in the case of a unified school district) of such taxable


                                       9
<PAGE>


property and (ii) any incorporated city or town of the State with such assent
may be allowed to become indebted in up to a 20% additional amount for (a)
supplying such city or town with water, artificial light, or sewers when the
works for supplying such water, light, or sewers are or shall be owned and
controlled by the municipality and (b) the acquisition and development by such
city or town of land or interests therein for open space preserves, parks,
playgrounds and recreational facilities. Annual property tax levies for the
payment of such debt, which pursuant to applicable statutes may only be issued
for limited purposes, are unlimited as to rate or amount. Other obligations may
be issued by counties, cities, towns, school districts and other municipal
corporations, sometimes without an election. Such obligations are payable from,
among other revenue sources, project revenue, special assessments, annual
budget appropriations and excise, transaction privilege and use taxes.


     Irrigation, power, electrical, agricultural improvement, drainage, flood
control and tax levying public improvement districts are exempt specifically
from the above-noted restrictions of the constitution and may issue obligations
for limited purposes, payable from a variety of revenue sources. For example,
Salt River Project Agricultural & Improvement District, an agricultural
improvement district that operates the Salt River Project (a federal
reclamation project and an electric system which generates, purchases, and
distributes electric power to residential, commercial, industrial, and
agricultural power users in a 2,900 square-mile service area around Phoenix),
may issue obligations payable from a number of sources.

     THE CALIFORNIA SERIES -- SPECIAL INVESTMENT CONSIDERATIONS. The following
describes certain risks with respect to municipal obligations of California
issuers in which the California Series may invest. This summarized information
is based on information drawn from official statements and prospectuses
relating to securities offerings of the State of California and other public
documents available as of the date of this Statement of Additional Information.
Although the Investment Manager has not independently verified such
information, it has no reason to believe that such information is not correct
in all material respects.

     The California Series will be affected by any political, economic or
regulatory developments affecting the ability of California issuers to pay
interest or repay principal. Provisions of the California Constitution and
State statutes which limit the taxing and spending authority of California
governmental entities may impair the ability of California issuers to maintain
debt service on their obligations. Future California political and economic
developments, constitutional amendments, legislative measures, executive
orders, administrative regulations, litigation and voter initiatives could have
an adverse effect on the debt obligations of California issuers.

     Certain debt obligations held by the California Series may be obligations
of issuers which rely in whole or in substantial part on California state
revenues for the continuance of their operations and payment of their
obligations. Whether and to what extent the California Legislature will
continue to appropriate a portion of the State's General Fund to counties,
cities and their various entities, is not entirely certain. To the extent local
entities do not receive money from the State to pay for their operations and
services, their ability to pay debt service on obligations held by the
California Series may be impaired.

     In 1978, Proposition 13, an amendment to the California Constitution, was
approved, limiting real property valuation for property tax purposes and the
power of local governments to increase real property tax revenues and revenues
from other sources. Legislation adopted after Proposition 13 provided for
assistance to local governments, including the redistribution of the
then-existing surplus in the General Fund, reallocation of revenues to local
governments, and assumption by the State of certain local government
obligations. However, more recent legislation reduced such state assistance.
There can be no assurance that any particular level of State aid to local
governments will be maintained in future years. In Nordlinger v. Hahn, the
United States Supreme Court upheld certain provisions of Proposition 13 against
claims that it violated the equal protection clause of the Constitution.

     In 1979, an amendment was passed adding Article XIIIB to the State
Constitution. As amended in 1990, Article XIIIB imposes an "appropriations
limit" on the spending authority of the State and local government entities. In
general, the appropriations limit is based on certain 1978-1979 expenditures,


                                       10
<PAGE>

adjusted annually to reflect changes in the cost of living, population and
certain services provided by State and local government entities.
"Appropriations limit" does not include appropriations for qualified capital
outlay projects, certain increases in transportation-related taxes, and certain
emergency appropriations.

     If a government entity raises revenues beyond its "appropriations limit"
in any year, a portion of the excess which cannot be appropriated within the
following year's limit must be returned to the entity's taxpayers within two
subsequent fiscal years, generally by a tax credit, refund or temporary
suspension of tax rates or fee schedules. "Debt service" is excluded from these
limitations, and is defined as "appropriations required to pay the cost of
interest and redemption charges, including the funding of any reserve or
sinking fund required in connection therewith, on indebtedness existing or
legally authorized as of January 1, 1979 or on bonded indebtedness thereafter
approved [by the voters]." In addition, Article XIIIB requires the State
Legislature to establish a prudent State reserve, and to require the transfer
of 50% of excess revenue to the State School Fund; any amounts allocated to the
State School Fund will increase the appropriations limit.

     In June 1982, the voters of California passed two initiative measures to
repeal the California gift and inheritance tax laws and to enact, in lieu
thereof, California death taxes. California voters also passed an initiative
measure to increase, for taxable years commencing on or after January 1, 1982,
the amount to account for the effects of inflation. Decreases in State and
local revenues in future fiscal years as a consequence of these initiatives may
result in reductions in allocations of state revenues to California issuers or
in the ability of California issuers to pay their obligations.

     In 1986, California voters approved an initiative statute known as
Proposition 62. This initiative (i) requires that any tax for general
governmental purposes imposed by local governments be approved by resolution or
ordinance adopted by a two-thirds vote of the governmental entity's legislative
body and by a majority vote of the electorate of the governmental entity, (ii)
requires that any special tax (defined as tax levied for other than general
governmental purposes) imposed by a local governmental entity be approved by a
two-thirds vote of the voters within that jurisdiction, (iii) restricts the use
of revenues from a special tax to the purposes or for the service for which the
special tax was imposed, (iv) prohibits the imposition of ad valorem taxes on
real property by local governmental entities except as permitted by the
Proposition 13 amendment, (v) prohibits the imposition of transaction taxes and
sales taxes on the sale of real property by local governments, (vi) requires
that any tax imposed by a local government on or after August 1, 1985, be
ratified by a majority vote of the electorate within two years of the adoption
of the initiative or be terminated by November 15, 1989, (vii) requires that,
in the event a local government fails to comply with the provisions of this
measure, a reduction of the amount of property tax revenue allocated to such
local government occurs in an amount equal to the revenues received by such
entity attributable to the tax levied in violation of the initiative, and
(viii) permits these provisions to be amended exclusively by the voters of the
State of California.

     In September 1995, the California Supreme Court upheld the
constitutionality of Proposition 62, creating uncertainty as to the legality of
certain local taxes enacted by non-charter cities in California without voter
approval. It is not possible to predict the impact of the decision.

     In November 1996, California voters approved Proposition 218. The
initiative applied the provisions of Proposition 62 to all entities, including
charter cities. It requires that all taxes for general purposes obtain a simple
majority popular vote and that taxes for special purposes obtain a two-thirds
majority vote. Prior to the effectiveness of Proposition 218, charter cities
could levy certain taxes such as transient occupancy taxes and utility user's
taxes without a popular vote. Proposition 218 will also limit the authority of
local governments to impose property-related assessments, fees and charges,
requiring that such assessments be limited to the special benefit conferred and
prohibiting their use for general governmental services. Proposition 218 also
allows voters to use their initiative power to reduce or repeal
previously-authorized taxes, assessments, fees and charges.

     In 1988, State voters approved Proposition 87, which amended Article XVI
of the State Constitution to authorize the State Legislature to prohibit
redevelopment agencies from receiving any property tax revenues raised by
increased property taxes to repay bonded indebtedness of local government which

                                       11
<PAGE>

is not approved by voters on or before January 1, 1989. It is not possible to
predict whether the State Legislature will enact such a prohibition, nor is it
possible to predict the impact of Proposition 87 on redevelopment agencies and
their ability to make payments on outstanding debt obligations.

     In November 1988, California voters approved Proposition 98. This
initiative requires that (i) revenues in excess of amounts permitted to be
spent and which would otherwise be returned by revision of tax rates or fee
schedules, be transferred and allocated (up to a maximum of 40%) to the State
School Fund and be expended solely for purposes of instructional improvement
and accountability. No such transfer or allocation of funds will be required if
certain designated state officials determine that annual student expenditures
and class size meet certain criteria as set forth in Proposition 98. Any funds
allocated to the State School Fund shall cause the appropriation limits to be
annually increased for any such allocation made in the prior year. Proposition
98 also requires the State of California to provide a minimum level of funding
for public schools and community colleges. The initiative permits the enactment
of legislation, by a two-thirds vote, to suspend the minimum funding
requirement for one year.

     Certain tax-exempt securities in which the California Series may invest
may be obligations payable solely from the revenues of specific institutions,
or may be secured by specific properties, which are subject to provisions of
California law which could adversely affect the holders of such obligations.
For example, the revenues of California health care institutions may be subject
to state laws, and California law limits the remedies of a creditor secured by
a mortgage or deed of trust on real property.


     California is the most populous state in the nation with a total
population currently estimated at 33.4 million. The State now comprises 12.4%
of the nation's population and 12.7% of its total personal income. Its economy
is broad and diversified with major concentrations in high technology research
and manufacturing, aerospace and defense-related manufacturing, trade,
entertainment, real estate, and financial services. After experiencing strong
growth throughout much of the 1980s, from 1990-1993 the State suffered through
a severe recession, the worst since the 1930's, heavily influenced by large
cutbacks in defense/aerospace industries and military base closures and a major
drop in real estate construction. California's economy has been performing
strongly since 1994, to the point where the State's economic growth is
outpacing the rest of the nation. The unemployment rate, while still higher
than the national average, fell to an average of 5.9% in 1998, and to 4.8% in
November, 1999, compared to over 10% at the worst of the recession.

     A significant downturn in U.S. stock market prices could adversely affect
California's economy by reducing household spending and business investment,
particularly in the important high technology sector. Moreover, a large and
increasing share of the State's General Fund revenue in the form of income and
capital gains taxes is directly related to, and would be adversely affected by
a significant downturn in the performance of the stock market.

     The recession severely affected state revenues while the State's health
and welfare costs were increasing. Consequently, the State had a lengthy period
of budget imbalance; the State's accumulated budget deficit approached $2.8
billion at its peak at June 30, 1993. The large budget deficits depleted the
State's available cash resources and it had to use a series of external
borrowings to meet its cash needs. With the end of the recession, the State's
financial condition improved in the 1995-96 through 1998-99 fiscal years, with
a combination of better than expected revenues, slowdown in growth of social
welfare programs, and continued spending restraint. The accumulated budget
deficit from the recession years was eliminated. No deficit borrowing has
occurred at the end of the last four fiscal years and the State's cash flow
borrowing was limited to $1.7 billion in 1998-99. The State issued $1.0 billion
of revenue anticipation notes for the 1999-2000 fiscal year.

     On June 29, 1999, the Governor of California signed the 1999-2000 Budget
Act. The Budget Act estimated General Fund revenues and transfers of $63.0
billion, and contained expenditures totaling $63.7 billion. The Budget Act also
contained expenditures of $16.1 billion from special funds and $1.5 billion
from bond funds. The Administration estimated a budget reserve balance at June
30, 2000, of approximately $880 million. Not included in this amount was an
additional $300 million which (after the Governor's vetoes) was "set aside" to
provide funds for employee salary increases (to be negotiated in bargaining
with employee unions), and for litigation reserves. The Budget Act anticipates
normal cash



                                       12
<PAGE>


flow borrowing during the fiscal year. Continued State economic expansion and
large revenue increases enabled the Governor and State legislature to provide
increases in spending programs in the 1999-2000 budget. These included large
increases in education and health and human services funding.

     The Governor's 2000-2001 proposed budget provides for total State spending
of $85.1 billion (excluding expenditures of federal funds and selected bond
funds), an increase of 3.7% from the current year. Approximately 80% of this
total is from the General Fund and 20% from special funds. The proposed budget
assumes that General Fund revenues will total $68.2 billion in 2000-01, a 4.7%
increase from the current year. General Fund expenditures are proposed to be
$68.8 billion, an increase of 4.5%. After accounting for various set-asides,
the year-end reserve is estimated to be $1.2 billion, or about 1.8% of total
2000-01 General Fund revenues.

     As of January 1, 2000, the State had over $17.5 billion aggregate amount
of its general obligation bonds outstanding. General obligation bond
authorizations in an aggregate amount of approximately $10.6 billion remained
unissued as of that date. The State also builds and acquires capital facilities
through the use of lease purchase borrowing. As of January 1, 2000, the State
had approximately $6.7 billion of outstanding Lease-Purchase Debt.

     In addition to the general obligation bonds, State agencies and
authorities had approximately $26 billion aggregate principal amount of revenue
bonds and notes outstanding as of June 30, 1999. Revenue bonds represent both
obligations payable from State revenue-producing enterprises and projects,
which are not payable from the General Fund, and conduit obligations payable
only from revenues paid by private users of facilities financed by such revenue
bonds. Such enterprises and projects include transportation projects, various
public works and exposition projects, educational facilities (including the
California State University and University of California systems), housing,
health facilities, and pollution control facilities.

     Because of the State of California's budget problems, the State's General
Obligation bonds were downgraded in July 1994 to A1 from Aa by Moody's, to A
from A+ by S&P, and to A from AA by Fitch. Moody's, Fitch and S&P expressed
uncertainty in the State's ability to balance its budget by 1996. However, in
1996, citing California's improving economy and budget situation, both Fitch
and S&P raised their ratings from A to A+. In October, 1997, Fitch raised its
rating from A+ to AA- referring to the State's fundamental strengths, the
extent of its economic recovery and the return of financial stability. In
October 1998, Moody's raised its rating from A1 to Aa3 citing the State's
continuing economic recovery and a number of actions taken to improve the
State's credit condition, including the rebuilding of cash and budget reserves.
In August 1999, S&P raised its rating from A+ to AA- citing the State's strong
economic performance and its return to structural fiscal balance.

     The State is a party to numerous legal proceedings, many of which normally
occur in governmental operations and which, if decided against the State, might
require the State to make significant future expenditures or impair future
revenue sources.

     Some local governments in California have experienced notable financial
difficulties. On December 6, 1994, Orange County, California, became the
largest municipality in the United States to file for protection under the
Federal bankruptcy laws. The filing stemmed from approximately $1.7 billion in
losses suffered by the County's investment pool due to investments in high risk
"derivative" securities. On June 12, 1996, it emerged from bankruptcy after the
successful sale of $880 million in municipal bonds allowed the county to pay
off the last of its creditors. On January 7, 1997, Orange County returned to
the municipal bond market with a $136 million bond issue maturing in 13 years
at an insured yield of 7.23%. In December, 1997, Moody's raised its ratings on
$325 million of Orange County pension obligation bonds to Baa3 from Ba. In
February 1998, Fitch assigned outstanding Orange County pension obligation
bonds a BBB rating. In September 1999, Moody's assigned the County an issuer
(implied general obligation) rating of Aa3 and, among other things, upgraded
the ratings on the County's pension obligation bonds to A1. In January 2000,
S&P upgraded its rating on the County's pension obligation bonds from BB to A-.


     Los Angeles County, the nation's largest county, has also experienced
financial difficulty. Between 1992 and 1995, the County's long-term bonds were
downgraded three times. This occurred as a result



                                       13
<PAGE>


of, and among other things, severe operating deficits for the county's health
care system. In addition, the county was affected by an ongoing loss of revenue
caused by state property tax shift initiatives in 1993 through 1995. The
County's improving financial condition has been reflected in improved general
obligation bond ratings. In June 1999, the Los Angeles County Board of
Supervisors approved a budget of approximately $15 billion for 1999-2000, up
from the $13.6 billion approved for the previous fiscal year. The County's
financial condition will continue to be affected by the large number of County
residents who are dependent on government services and by a structural deficit
in its health department.


     The effect of these various constitutional and statutory amendments and
budget developments upon the ability of California issuers to pay interest and
principal on their obligations remains unclear and in any event may depend upon
whether a particular California tax-exempt security is a general or limited
obligation bond and on the type of security provided for the bond. It is
possible that other measures affecting the taxing or spending authority of
California or its political subdivisions may be approved or enacted in the
future.

     THE FLORIDA SERIES -- SPECIAL INVESTMENT CONSIDERATIONS. The following
information is provided only for general information purposes and is not
intended to be a description or summary of the investment considerations and
factors which may have an affect on the Florida Series or the obligations of
the issuers in which the Florida Series may invest. Prospective investors must
read the entire prospectus to obtain information essential to the making of an
informed investment decision.

     The Florida Series invests primarily in municipal securities and
obligations of counties, cities, school districts, special districts, and other
government authorities and issuers of the State of Florida, the interest on
which is excludable from gross income for federal income tax purposes. The
Florida Series may also invest in tax-exempt, municipal securities and
obligations that are issued by governmental entities for the benefit of certain
private obligors. The repayment of such securities and obligations ultimately
is the responsibility of the private obligor and the governmental issuer
typically is not responsible for the repayment of such securities and
obligations. The municipal securities market of Florida is very diverse and
includes many different types of obligations that are issued by a number of
different issuers and which are payable from a variety of revenue sources.
Accordingly, the ability of Florida issuers or private obligors to meet their
obligations with respect to such municipal securities is influenced by various
political, legal, economic and regulatory factors affecting such issuers, the
State of Florida and the repayment sources supporting municipal obligations. If
any of such issuers or private obligors cannot satisfy their repayment
obligations, for any reason, the income, value and liquidity of the Florida
Series may be adversely affected.


     As of January 1, 2000, the State of Florida's general obligation debt
maintained ratings of "AA+" from Standard & Poor's Ratings Group, "AA" from
Fitch IBCA and "Aa2" from Moody's Investors Service. It should be noted,
however, that the Florida Series is not required to invest in State of Florida
general obligation debt and, accordingly, may or may not have any investments
in State of Florida general obligation debt from time to time. Some issuers in
which the Florida Series invests may have ratings lower than the State's
ratings noted above while others may have higher ratings.

     Florida presently is the fourth largest state in the United States and
continues to be one of the most rapidly growing states. Between 1980 and 1990,
Florida's population increased by approximately 3.2 million people, the second
largest population increase for any state during the decade (California was
first). During such period of time, Florida's total percentage growth in
population was 32.7%, the fourth largest percentage increase among states.
Florida's population has continued to grow since 1990, but at a slower pace
than during the 1980s and prior decades. As of April 1, 1999, Florida's
population had grown approximately 18.4% since April 1, 1990 to a total
population of 15,322,040, making Florida the 9th fastest growing state in the
1990's.


     Florida's principal economic sectors include services and tourism, retail,
light manufacturing, particularly in the electronic, chemical and
transportation areas, finance and insurance, real estate, wholesale trade,
transportation and communications, agriculture, government and the military.
During the last few calendar years Florida's unemployment figures have
approximated the national average.

Florida's economy has strengthened over the last several years reflecting the
strong national economy. Most of Florida's economic sectors are expected to
grow in the future and in light of Florida's geographic location and diverse
population, it is anticipated that Florida will continue to benefit from the
expanding world markets, especially Latin America.


     The State of Florida and its political subdivisions are each required by
law to maintain balanced budgets. In order to satisfy this requirement, Florida
government entities have utilized a combination of spending reductions and
revenue enhancements. From time to time, tax and/or spending limitation
initiatives are introduced by the Florida Legislature or are proposed by the
citizens of the State in the form of amendments to the Florida Constitution.
Two such amendments became effective during the 1990's and are generally
described below.


     By voter referendum held in 1992, the Florida Constitution was amended by
adding a subsection which, in effect, limits the annual increases in assessed
just value of homestead property to the lesser of (1) three percent of the
assessment for the prior year, or (2) the percentage change in the Consumer
Price Index, as described and calculated in such amendment. The amendment
further provides that (1) no assessment shall exceed just value, (2) after any
change of ownership of homestead property or upon termination of homestead
status, such property shall be reassessed at just value as of January 1 of the
year following the year of sale or change of status, (3) new homestead property
shall be assessed at just value as of January 1 of the year following the
establishment of the homestead, and (4) changes, additions, reductions or
improvements to homestead property shall initially be assessed as provided for
by general law, and thereafter as provided in the amendment. Pursuant to a
Florida Supreme Court ruling, the amendment became effective on January 1,
1995. Studies have been conducted analyzing the effect of this amendment on
property values and tax collections in Florida since its effective date. Such
studies conclude that while the assessed values of homestead property within
the State have been lower due to the amendment, the impact on total property
tax revenues for local governments within the State has been small due to
growth in the total property tax base and the property tax revenues received
with respect to non-homestead property. It is expected that the amendment's
impact will be similar in future years.


     In the 1994 general election, Florida voters approved an amendment to the
Florida Constitution which is commonly referred to as the "Limitation On State
Revenues Amendment." This amendment provides that state revenues collected for
any fiscal year shall be limited to state revenues allowed under the amendment
for the prior fiscal year plus an adjustment for growth. Growth is defined as
an amount equal to the average annual rate of growth in Florida personal income
over the most recent twenty quarters times the state revenues allowed under the
amendment for the prior fiscal year. State revenues collected for any fiscal
year in excess of this limitation are required to be transferred to a budget
stabilization fund until the fund reaches the maximum balance specified in the
amendment to the Florida Constitution, and thereafter is required to be
refunded to taxpayers as provided by general law. The limitation on state
revenues imposed by the amendment may be increased by the Legislature, by a
two-thirds vote in each house. This amendment took effect on January 1, 1995,
and was first applicable to the State's fiscal year 1995-96. This amendment has
had no impact for the state fiscal years following the effective date of the
amendment, as State revenues were substantially below the constitutionally
imposed limitation. It is projected that State revenues for the next few fiscal
years also will not exceed the applicable revenue limitations. Estimates or
projections beyond such period cannot be made with any certainty at this time.

     THE MASSACHUSETTS SERIES -- SPECIAL INVESTMENT CONSIDERATIONS. Between
1982 and 1988 The Commonwealth of Massachusetts had a strong economy which was
evidenced by low unemployment and high personal income growth as compared to
national trends. The Commonwealth experienced a significant economic slowdown
from 1988 through 1992, with particular deterioration in the construction, real
estate, insurance, financial and manufacturing sectors, including certain high
technology areas. Economic activity has since improved and led to improvements
in the housing industry and employment rates. Unemployment had risen to 8.5% in
1992, as compared to a national average of 7.4%; but decreased to 5.1% at the
end of fiscal 1995 and further decreased to 4.1% at the end of fiscal 1996. The
Massachusetts unemployment rate at the end of 1998 was 3.0% as compared to the
national rate of 4.5%. At the end of fiscal year 1999, the Massachusetts
unemployment rate was 3.1% as compared to the national average of 4.2%.



                                       15
<PAGE>


     The recent economic growth has resulted in a progressive growth of state
tax revenues since 1993. Tax revenues for fiscal year 1998 are currently
projected to be approximately 2.6% above fiscal year 1997. The Commonwealth had
a budgetary deficit for fiscal year 1989 and 1990 of $466.4 million and
$1,362.7 billion respectively. Deficits were avoided in fiscal 1991 and 1992,
and a surplus was achieved from 1993-1999. In 1992, Standard & Poor's and
Moody's raised their ratings of the Commonwealth's general obligation bonds
from BBB and Baa1, respectively, to A and A, respectively and Standard & Poor's
further raised such ratings to A+ in 1993. Currently, the Commonwealth's
general obligation bonds are rated Aa3 and AA- by Moody's and Fitch IBCA,
respectively. From time to time, the rating agencies may further change their
ratings in response to budgetary matters or other economic indicators. Growth
of tax revenues in the Commonwealth is limited by law. Effective July 1, 1990,
limitations were placed on the amount of direct bonds the Commonwealth could
have outstanding in a fiscal year, and the amount of the total appropriation in
any fiscal year that may be expended for debt service on general obligation
debt of the Commonwealth (other than certain debt incurred to pay the fiscal
1990 deficit and certain Medicaid reimbursement payments for prior fiscal
years) was limited to ten percent. Moreover, Massachusetts local governmental
entities are subject to certain limitations on their taxing power that could
affect their ability or the ability of the Commonwealth to meet their
respective financial obligations.


     If either Massachusetts or any of its local governmental entities is
unable to meet its financial obligations, the income derived by the
Massachusetts Series, the Series' net asset value, the Series' ability to
preserve or realize capital appreciation or the Series' liquidity could be
adversely affected.


     Between 1982 and 1988 The Commonwealth of Massachusetts had a strong
economy which was evidenced by low unemployment and high personal income growth
as compared to national trends. Economic growth in the Commonwealth slowed from
1988 to 1992, however, as the Commonwealth experienced a significant economic
slowdown, with particular deterioration in the construction, real estate,
financial, insurance and manufacturing sectors, including certain high
technology areas. Economic activity began to improve in 1993 and continued to
improve in 1994, particularly in the construction and service sectors as well
as in housing sales. Since 1995, the services and wholesale and retail trade
industries have been the two largest industries by number of employees. A
continued low rate of inflation is expected to keep wage growth low and allow
for slow-paced positive growth in the Massachusetts economy.

     Growth of state tax revenues in the Commonwealth slowed considerably in
fiscal 1988, fiscal 1989 and fiscal 1990, while expenditures for state programs
and services increased. Fiscal 1989 and 1990 ended with budgetary deficits of
$466.4 million and $1.362 billion, respectively. The Commonwealth achieved
budget surpluses in each fiscal year since 1991. The Commonwealth's fiscal 1999
budgeted expenditures and other uses are estimated to be approximately $20.8
billion. On a statutory basis of accounting, the Commonwealth has achieved a
positive fund balance for each of the last five years. During this period, the
fund balance increased from $726.5 million in fiscal year 1995 to $2.1 billion
in 1999 for a cumulative improvement of $1.4 billion. In 1991, Standard &
Poor's and Moody's lowered their ratings of the Commonwealth's general
obligation bonds from AA and Aa, respectively, to BBB and Baa, respectively,
but in 1992 each raised such ratings to A and in 1993, Standard & Poor's
further increased such rating to A+. From time to time, the rating agencies may
further change their ratings. Currently, the Commonwealth's general obligation
bonds are rated A1 and AA by Moody's and Standard & Poor's, respectively.

     The Commonwealth's fiscal 1991 budget achieved a small surplus principally
as a result of a one time reimbursement claim for Federal funds available under
Medicaid reimbursement programs. In fiscal 1992 and 1993, budget surpluses were
achieved through appropriation and spending reductions and a significant
increase in revenues attributable to tax increases and enhanced revenue
collections. Fiscal 1993 and 1994 tax revenues increased to account for
approximately 45% of all revenues and financing sources. Fiscal 1996 tax
revenues increased to account for approximately 47.5% of all revenues and
financing sources. Fiscal 1997 tax revenues accounted for 47.7% and fiscal year
1998 tax revenues accounted for 44.9%. Tax revenues for 2000 are estimated to
be 2.9% above fiscal 1999 actual collections of $14.3 billion.



                                       16
<PAGE>

     Growth of tax revenues in the Commonwealth is limited by law. In addition,
effective July 1, 1990, limitations were placed on the amount of direct bonds
(other than Fiscal Recovery Bonds and certain other limited exceptions) the
Commonwealth may have outstanding in a fiscal year, and the amount of the total
appropriation in any fiscal year that may be expended for payment of principal
of and interest on general obligation debt (other than Fiscal Recovery Bonds)
of the Commonwealth was limited to 10 percent of such appropriation.

     Furthermore, certain of the Commonwealth's cities and towns have at times
experienced serious financial difficulties which have adversely affected their
credit standing. The recurrence of such financial difficulties, or financial
difficulties of the Commonwealth, could adversely effect the market values and
marketability of, or result in default in payment on, outstanding obligations
issued by the Commonwealth or its public authorities or municipalities. In
addition, the Massachusetts statutes which limit the taxing authority of the
Commonwealth or certain Massachusetts governmental entities may impair the
ability of issuers of some Massachusetts obligations to pay debt service on
their obligations.

     In Massachusetts the tax on personal property and real estate is virtually
the only source of tax revenues available to cities and towns to meet local
costs. "Proposition 2 1/2," an initiative petition adopted by the voters of the
Commonwealth of Massachusetts on November 4, 1980, limits the power of
Massachusetts cities and towns and certain tax-supported districts and public
agencies to raise revenue from property taxes to support their operations,
including the payment of certain debt service. Proposition 2 1/2 required many
cities and towns to reduce their property tax levels to a stated percentage of
the full and fair cash value of their taxable real estate and personal property
and limited the amount by which the total property taxes assessed by a city or
town might increase from year to year.


     To offset shortfalls experienced by local governments as a result of the
implementation of Proposition 2 1/2, the state government increased direct
local aid from the 1981 level of $1.632 billion to the fiscal 1989 level of
$2.9 billion; however, direct local aid dropped in fiscal 1991 and 1992 to
approximately $2.6 billion and $2.3 billion, respectively. In the period 1993
to 1996, direct local aid has increased from $2.5 billion to $3.3 billion. In
fiscal 1997, 1998 and 1999, direct local aid increased to $3.7 billion, $3.9
billion and $4.3 billion, respectively.


     THE MICHIGAN SERIES -- SPECIAL INVESTMENT CONSIDERATIONS. The information
set forth below is derived from official statements prepared in connection with
the issuance of obligations of the State of Michigan and other sources that are
generally available to investors, including the State of Michigan Comprehensive
Annual Financial Reports for the fiscal years ended September 30, 1996, 1997
and 1998. The information is provided as general information intended to give a
recent historical description and is not intended to indicate further or
continuing trends in the financial or other positions of the State of Michigan.
Such information constitutes only a brief summary, relates primarily to the
State of Michigan, does not purport to include details relating to other
potential issuers within the State of Michigan whose securities may be
purchased by the Michigan Series and does not purport to be a complete
description.


     Economy. The principal sectors of Michigan's economy are durable goods
manufacturing (including automobile and office equipment manufacturing),
tourism and agriculture. As reflected in historical employment figures,
Michigan's economy has lessened its dependence upon durable goods
manufacturing. In 1960, employment in such industry accounted for 33% of
Michigan's labor force. This figure fell to 16.1% in 1998. Durable goods
manufacturing (including auto-related manufacturing) continues, however, to be
an important part of Michigan's economy. This industry is highly cyclical.
Historically, during periods of economic decline or slow economic growth, the
cyclical nature of this industry has adversely affected the revenue streams of
Michigan and its political subdivisions because it has adversely impacted
certain tax sources, particularly sales taxes, income taxes and single business
taxes. Income per capita in Michigan in 1998 was approximately 0.9% lower than
the national average. For the sixth consecutive year, contrary to the prior
historical trend, the average annual unemployment rate for 1999 in Michigan was
slightly lower than the average rate for the United States.

     Budget. The budget of Michigan is a complete financial plan and
encompasses the revenues and expenditures, both operating and capital outlay,
of the General Fund and special revenue funds. The budget is prepared on a
basis consistent with generally accepted accounting principles. Michigan's
fiscal



                                       17
<PAGE>


year begins on October 1 and ends September 30 of the following year. Under
Michigan law, the executive budget recommendations for any fund may not exceed
the estimated revenue thereof, and an itemized statement of estimated revenues
in each operating fund must be contained in an appropriation bill as passed by
the Legislature, the total of which may not be less than the total of all
appropriations made from the fund for that fiscal year. The Michigan
Constitution provides that proposed expenditures and revenues of any fund must
be in balance and that any prior year's surplus or deficit in any fund must be
included in the succeeding year's budget for that fund.

     Michigan's Constitution limits the amount of total State revenues that may
be raised from taxes and other sources. State revenues (excluding federal aid
and revenues used for payment of principal of and interest on general
obligation bonds) in any fiscal year are limited to a specified percentage of
Michigan personal income in the prior calendar year or average thereof in the
prior three calendar years, whichever is greater. The percentage is based upon
the ratio of the 1978-79 fiscal year revenues to the total 1977 Michigan
personal income (the total income received by persons in Michigan from all
sources as defined and officially reported by the United States Department of
Commerce). If revenues in any fiscal year exceed the revenue limitation by 1
percent or more, the entire amount exceeding the limitation must be rebated in
the following fiscal year's personal income tax or single business tax. Annual
excesses of less than 1 percent may be transferred into Michigan's
Counter-Cyclical Budget and Economic Stabilization Fund ("BSF"). Michigan may
raise taxes in excess of the limit in emergency situations when deemed necessary
by the Governor and two-thirds of the members of each house of the Legislature.

     Michigan finances its operations through its General Fund and special
revenue funds. The General Fund receives revenues that are not specifically
required to be included in the special revenue funds. Approximately 55% of
General Fund revenues are obtained from the payment of state taxes, and
approximately 45% are obtained from federal and nontax revenue sources. The
majority of the revenues from state taxes are from the personal income tax, the
single business tax and the sales and use tax. In addition, Michigan levies
various other taxes. Over two-thirds of total General Fund expenditures are
made for education, the Family Independence Agency and the Department of
Community Health. State support of public education consists of aid to local
and intermediate school districts (which provide education to children in
grades kindergarten through 12), charter schools, State universities, community
colleges, and the Department of Education which is responsible for
administering a variety of programs that provide additional special purpose
funding for local and intermediate school districts. The Family Independence
Agency and the Department of Community Health administer economic, social and
medical assistance programs in Michigan, including Medicare, Medicaid and the
Temporary Assistance to Needy Families block grant.

     Michigan ended fiscal years 1996-97 and 1997-98 with General Fund
surpluses of $63.3 million and $55.2 million respectively. In fiscal year
1995-96, the State of Michigan made deposits into the BSF totaling $150.5
million. The unreserved balance for the BSF as of the end of fiscal year
1997-98, reported on a cash basis, was $1,000.5 million.

     For the fiscal year 1997-1998, General Fund revenues and other financing
sources (including restricted sources, operating transfers in, and capital
lease acquisitions) totaled approximately $19.3 billion while expenditures and
other financing uses totaled approximately $18.8 billion. The unreserved fund
balance of the General Fund was $55.2 million at that fiscal year-end.

     During fiscal year 1997-98, an error was identified pertaining to the
Medicaid program administered by the Department of Community Health (DCH). Over
a ten-year period, DCH did not properly record all Medicaid expenditures and
revenues on a modified accrual basis as required by GAAP. For the fiscal year
ended September 30, 1997, the General Fund did not reflect Medicaid
expenditures of $178.7 million and federal revenue of $24.6 million. As a
result, the fiscal year 1997-98 beginning fund balances were reduced by $154.1
million, to $893.1 million, to account for the correction of the prior period
error.

     On January 27, 2000, the State's governor presented to the Legislature the
proposed budget for fiscal year 2000-01 which proposes $36.2 billion of
expenditures. As of February 11, 2000, this proposed budget was under review by
the Legislature.



                                       18

     DEBT. The Michigan Constitution limits Michigan general obligation debt to
(i) short-term debt for State operating purposes which must be repaid in the
same fiscal year that it is issued and which cannot exceed 15% of the
undedicated revenues received by the State during the preceding fiscal year,
(ii) short-and long-term debt unlimited in amount for the purpose of making
loans to school districts and (iii) long-term debt for voter-approved purposes.


     Michigan has issued and has outstanding general obligation full faith and
credit bonds for water resources, environmental protection program, recreation
program and school loan purposes, which as of September 30, 1998 totaled
approximately $874 million. In November 1988 Michigan's voters approved the
issuance of $800 million of general obligation bonds for environmental
protection and recreational purposes of which approximately $173 million
remained to be issued as of September 30, 1998.

     On April 28, 1998, the State issued $160 million in general obligation
school loan bonds for school loan purposes. On June 3, 1998, the State issued
$90 million in general obligation environmental protection program bonds. In
November 1998, the Michigan voters approved the issuance of $675 million in
general obligation indebtedness for environmental and other purposes, of which
the State issued $96,860,000 million in general obligation bonds in October
1999.


     There are also various state authorities and special purpose agencies
created by Michigan which issue bonds secured by specific revenues. Such debt
is not a general obligation of Michigan.


     Litigation. Michigan is a party to various legal proceedings seeking
damages or injunctive or other relief. In addition to routine litigation,
certain of these proceedings could, if unfavorably resolved from the point of
view of Michigan, substantially affect State programs or finances. Those
lawsuits involve programs generally in the areas of corrections, tax
collection, commerce and budgetary reductions to school districts, governmental
units and court funding. Relief sought includes damages in tort cases
generally, alleviation of prison overcrowding, improvement of prison medical
and mental health care, and refund claims under Michigan taxes. In an order
dated June 10, 1997 and a decision rendered July 31, 1997, the Michigan Supreme
Court decided, in the consolidated cases of Durant v. State of Michigan and
Schmidt v. State of Michigan, that the state must pay $212 million to 84 school
districts to settle litigation involving state mandates. The governor signed
legislation providing $212 million to the 84 school districts. The $212 million
was paid from the BSF on April 15, 1998. Approximately 400 other school
districts asserted similar claims; the State has settled with these districts
for payments that will, over fifteen years beginning in the fiscal year
1998-99, total $632 million. This amount is to be paid from the BSF and the
General Fund; half in annual payments over ten years, and half in annual
payments over fifteen years.

     On May 14, 1998, more than 100 Michigan school districts and individuals
filed suit in the Michigan Court of Appeals, asserting that the current version
of the state school aid act violates the Michigan Constitution in much the same
manner as prior versions of the act were ruled unconstitutional by the Michigan
Supreme Court in Durant, Durant, et al v State, et al ("Durant II"). The Durant
II plaintiffs are seeking a monetary remedy of approximately $347 million for
the 1997-1998 school year for the State's alleged underfunding of special
education services, special education transportation, and school lunch
programs. The Durant II plaintiffs are also requesting a declaratory judgment
that the current version of the state school aid act will not provide proper
funding levels for future school years. They also seek attorneys' fees and
costs of the litigation. On October 30, 1998, the school districts moved to
amend their complaint to challenge the newly-enacted amendments to the State
School Aid Act, 1998 PA 339, to add claims for the 1999-2000 fiscal year and to
add a new count for mandamus against the state treasurer. On December 2, 1998,
the Court of Appeals granted the Durant II plaintiffs' motion to amend the
complaint and established a briefing schedule. On September 17, 1999, the Court
of Appeals granted plaintiffs' motion to file a second amended complaint which
added approximately 125 new school districts and 125 individuals as additional
plaintiffs. In October 1999, the Court of Appeals granted the plaintiffs'
motion for summary disposition on the count seeking declaratory relief. On all
other counts, the Court of Appeals ruled in favor of the State. On February 4,
2000, the Court of Appeals granted a stay in the proceedings pending appeal to
the Michigan Supreme Court. The ultimate disposition of the legal proceedings
described in this paragraph is not presently determinable.

     10th Judicial Circuit, et al. v. State of Michigan, et al.: On August 22,
1994, the Ingham Circuit and Probate Courts, together with the 55th District
Court, filed suits in the Court of Claims and Ingham County Circuit Court
against the State of Michigan and Ingham County for declaratory and injunctive
relief, and for damages, due to the alleged failure of the State Court
Administrative Office to properly calculate Ingham County's reimbursement under
MCL 600.9947, the court funding statute. This case was dismissed by stipulation
of the parties because the plaintiffs are members of a class action suit filed
in the Saginaw County Circuit Court with claims identical to those filed in the
Court of Claims and Ingham County Circuit Court. The plaintiffs in the
continuing case assert that the amount in controversy exceeds five million
dollars. The court granted final class certification on April 26, 1996. The
case is currently pending in Saginaw County Circuit Court.

     Year 2000. On January 25, 2000, the department responsible for Michigan's
Year 2000 Project reported that the State did not experience any significant
events related to the so-called "Y2K Bug."

     Property Tax Initiatives. On March 15, 1994, Michigan voters approved a
property tax and school finance reform measure known as Proposal A. Under
Proposal A, as approved, effective May 1, 1994, the State sales and use tax
increased from 4% to 6%, the State income tax decreased from 4.6% to 4.4%, the
cigarette tax was increased from $.25 to $.75 per pack and an additional tax of
16% of the wholesale price began to be imposed on certain other tobacco
products. A .75% real estate transfer tax became effective on January 1, 1995.
Beginning in 1994, a State of Michigan property tax of six mills began to be
imposed on all real and personal property currently subject to the general
property tax. All local school boards are authorized, with voter approval, to
levy up to the lesser of 18 mills or the number of mills levied in 1993 for
school operating purposes on nonhomestead property and nonqualified
agricultural property. Proposal A contains additional provisions regarding the
ability of local school districts to levy taxes, as well as a limit on annual
assessment increases for each parcel of property beginning in 1995; increases
for each parcel of property are limited to the lesser of 5% or the rate of
inflation. When property is sold, its assessed value reverts to the current
assessment level of 50% of true cash value. Under Proposal A, much of the
additional revenue generated by the new taxes will be dedicated to the State's
School Aid Fund. Proposal A shifts significant portions of the cost of local
school operations from local school districts to the State of Michigan and
raises additional State revenues to fund those additional State expenses. Those
additional revenues will be included within the State's constitutional revenue
limitations and may impact the State's ability to raise additional revenues in
the future.

     Ratings. As of October 12, 1999, Michigan's general obligation bonds were
rated "Aa1" by Moody's Investors Service, "AA+" by Standard & Poor's Ratings
Services and "AA+" by Fitch Investors Service. All of these ratings represent
an upgrade of previous ratings of Aa2, AA, and AA respectively. These upgrades
occurred in early 1998, and were reaffirmed as recently as October 1999. To the
extent that the portfolio of the Michigan Series is composed of revenue
obligations of the State of Michigan or revenue or general obligations of local
governments or State or local authorities, rather than general obligations of
the State of Michigan, ratings on such components of the Michigan Series will
be different from those given to the general obligations of the State of
Michigan and their value may be independently affected by economic matters not
directly impacting the State.


     TREATMENT OF DISTRIBUTIONS FOR MICHIGAN TAX PURPOSES. Under existing
Michigan law, to the extent that the distributions from the Michigan Series
qualify as "exempt-interest dividends" of a regulated investment company under
Section 852(b)(5) of the Code which are attributable to interest on tax-exempt
obligations of the State of Michigan, its political or governmental
subdivisions, or its governmental agencies or instrumentalities ("Michigan
Obligations"), or obligations of the United States or its agencies or
possessions that are exempt from state taxation, such distributions will also
not be subject to Michigan income tax or Michigan single business tax.

     To the extent that distributions of the Michigan Series are derived from
other income, including long- or short-term capital gains, the distributions
will not be exempt from Michigan income tax or Michigan single business tax.


                                       20
<PAGE>


     Certain Michigan cities have adopted Michigan's uniform city income tax
ordinance, which under the Michigan city income tax act is the only income tax
ordinance that may be adopted by cities in Michigan. To the extent the
distributions on the Michigan Series are not subject to Michigan income tax,
they are not subject to any Michigan city's income tax.


     THE MINNESOTA SERIES -- SPECIAL INVESTMENT CONSIDERATIONS. The information
set forth below is derived from official statements prepared in connection with
the issuance of obligations of the State of Minnesota and other sources that
are generally available to investors. The information is provided as general

     The State of Minnesota has experienced certain budgeting and financial
problems since 1980. However, in recent years, Accounting General Fund balances
have been positive.


     In February 1992 the Commissioner of Finance estimated the Accounting
General Fund balance at June 30, 1993, at negative $569 million. The balance at
June 30, 1995, was projected at negative $1.75 billion.

     The 1992 Legislature reduced expenditures by $262 million for the biennium
ending June 30, 1993, enacted revenue measures expected to increase revenue by
$149 million, and reduced the budget reserve by $160 million to $240 million.

     After the Legislature adjourned in April 1992, the Commissioner of Finance
estimated the Accounting General Fund balance at June 30, 1993, at $2.4
million, and projected the balance at June 30, 1995, at negative $837 million.
A November 1992 forecast estimated the balance at June 30, 1993, at positive
$217 million and projected the balance at June 30, 1995, at negative $769
million.

     A March 1993 forecast projected an Accounting General Fund balance at June
30, 1995, at negative $163 million out of a budget for the biennium of
approximately $16.7 billion, and estimated a balance at June 30, 1997, at
negative $1.6 billion out of a budget of approximately $18.7 billion.

     The 1993 Legislature authorized $16.519 billion in spending for the
1993-1995 biennium, an increase of 13.0 percent from 1991-1993 expenditures.
Resources for the 1993-1995 biennium were projected to be $16.895 billion,
including $657 million carried forward from the previous biennium. The $16.238
billion in projected non-dedicated and dedicated revenues was 10.3 percent
greater than in the previous biennium and included $175 million from revenue
measures enacted by the 1993 Legislature. The Legislature increased the health
care provider tax to raise $79 million, transferred $39 million into the
Accounting General Fund and improved collection of accounts receivable to
generate $41 million.

     After the Legislature adjourned in May 1993, the Commissioner of Finance
estimated that at June 30, 1995, the Accounting General Fund balance would be
$16 million and the budget reserve, as approved by the 1993 Legislature, would
be $360 million. The Accounting General Fund balance at June 30, 1993, was $463
million.

     The Commissioner of Finance, in a November 1993 forecast, estimated the
Accounting General Fund balance at June 30, 1995, at $430 million, due to
projected increases in revenues and reductions in expenditures, and the balance
at June 30, 1997, at $389 million. The Commissioner recommended that the budget
reserve be increased to $500 million. He estimated that if current laws and
policies continued unchanged, revenue would grow 7.7 percent and expenditures
6.0 percent in the 1995-1997 biennium.

     A March 1994 forecast projected an Accounting General Fund balance at June
30, 1995, at $623 million, principally due to a projected $235 million increase
in revenues to $16.6 billion for the biennium. The balance at June 30, 1997,
was estimated to be $247 million.

     The 1994 Legislature provided for a $500 million budget reserve;
appropriated to school districts $172 million to allow the districts, for
purposes of state aid calculations, to reduce the portion of property tax
collections that the school districts must recognize in the fiscal year during
which they receive the property taxes; increased expenditures $184 million; and
increased expected revenues $4 million.


                                       21

     Of the $184 million in increased expenditures, criminal justice
initiatives totaled $45 million, elementary and higher education $31 million,
environment and flood relief $18 million, property tax relief $55 million, and
transit $11 million. A six-year strategic capital budget plan was adopted with
$450 million in projects financed by bonds supported by the Accounting General
Fund. Other expenditure increases total $16.5 million.

     Included in the expected revenue increase of $4 million were conformity
with federal tax changes to increase revenues $27.5 million, a sales tax
phasedown on replacement capital equipment and miscellaneous sales tax
exemptions decreasing revenues $17.3 million, and other measures decreasing
revenues $6.2 million.

     After the Legislature adjourned in May 1994, the Commissioner of Finance
estimated the Accounting General Fund balance at June 30, 1995, at $130
million.

     The Commissioner of Finance, in a November 1994 forecast, estimated the
Accounting General Fund balance at June 30, 1995, at $268 million, due to
projected increases in revenues and decreases in expenditures, and the balance
at June 30, 1997, at $190 million.

     A February 1995 forecast projected an Accounting General Fund balance at
June 30, 1995, at $383 million, due to a $93.5 million increase in projected
revenues and a $21.0 million decrease in expenditures. The balance at June 30,
1997, was projected at $250 million.

     The 1995 Legislature authorized $18.220 billion in spending for the
1995-1997 biennium, an increase of $1.395 billion, 8.3 percent, from 1993-1995
expenditures. Resources for the 1995-1997 biennium were projected to be $18.774
billion, including $921 million carried forward from the previous biennium.

     The Legislature authorized 7.1 percent more spending for elementary and
secondary education in the 1995-1997 biennium than in 1993-1995, 0.9 percent
more in local government aids, 14.2 percent more for health and human services,
2.3 percent more for higher education, and 25.1 percent more for corrections.
The Legislature set the budget reserve at $350 million and established a
supplementary reserve of $204 million in view of predicted federal cutbacks.

     After the Legislature adjourned in May 1995, the Commissioner of Finance
estimated that at June 30, 1997, the Accounting General Fund balance would be
zero. The Accounting General Fund balance at June 30, 1995, was $481 million.

     The Commissioner of Finance, in a November 1995 forecast, estimated the
Accounting General Fund balance at June 30, 1997, at $824 million, due to a
$490 million increase in revenues from those projected in May 1995, a $199
million reduction in projected expenditures, and a $135 million increase in the
amount carried forward from the 1993-1995 biennium. An improved national
economic outlook increased projected net sales tax revenue $257 million and
reduced projected human services expenditures $231 million. The Commissioner
estimated the Accounting General Fund balance at June 30, 1999, at negative $28
million.

     Only $15 million of the $824 million projected 1995-1997 surplus was
available for spending. The statutes require that an additional $15 million be
placed in the supplementary budget reserve, and an additional $794 million must
be appropriated to school districts to allow the districts, for purposes of
state aid calculations, to eliminate the 48 percent of property tax collections
that the school districts must recognize in the fiscal year during which they
receive the property taxes.

     A February 1996 forecast projected an Accounting General Fund balance at
June 30, 1997, at $873 million, due to a $104 million increase in projected
revenues, a $19 million increase in expenditures, and a $36 million reduction
in the June 30, 1995, ending balance. The amount available for spending
increased from $15 million to $64 million.

     In February 1996, the Commissioner of Finance estimated the Accounting
General Fund balance at June 30, 1999, at $54 million.


                                       22

     The 1996 Legislature reduced the State of Minnesota's commitment to
eliminate the so-called school recognition shift. The 1995 Legislature had
voted to allow school districts, for purposes of state aid calculations, to
eliminate the 48 percent of property tax collections that the school districts
must recognize in the fiscal year during which they receive the property taxes.
The 1996 Legislature raised the percentage for the 1995-1997 biennium from zero
to 7 percent, saving the State $116 million.

     The 1996 Legislature increased expenditures $130 million, including $37
million for elementary education and youth development; $14 million for higher
education; $17 million for health systems and human services reforms; $16
million for public safety and criminal justice; and $36 million for
transportation, environment and technology. The Legislature also approved $614
million in capital projects to be funded by general obligation bonds and
appropriations and increased expected revenues $5 million.

     After the Legislature adjourned in April 1996, the Commissioner of Finance
estimated the Accounting General Fund balance at June 30, 1997, at $1 million.
The Accounting General Fund balance at June 30, 1996, was $445 million.

     The Commissioner of Finance, in a November 1996 forecast, estimated the
Accounting General Fund balance at June 30, 1997, at $793 million, due to a
$646 million increase in revenues from those projected in April 1996, a $209
million reduction in expenditures, and $63 million in other changes. The
longest period of national economic growth since World War II, through
mid-1999, was forecast. Individual income taxes were forecast to be $427
million more than projected in April 1996, and sales taxes $81 million more. Of
the $209 million reduction in forecast expenditures, $199 million were health
and human services expenditures.

     Existing statutes require the first $114 million of the forecast balance
to be dedicated to a new education aid reserve for use in the 1997-1999
biennium. Another $157 million must be used to increase from 85 to 90 percent
the portion of state aid to school districts that is paid in the fiscal year
during which the districts become entitled to aid.

     A February 1997 forecast projected an Accounting General Fund balance at
June 30, 1997, at $866 million (after taking into account the $114 million and
$157 million items referred to above), due to a $236 million increase in
projected revenues and a $108 million decrease in expenditures. The balance at
June 30, 1999, was projected at $1.7 billion.

     The 1997 Legislature, in a regular session and June and August special
sessions, authorized $20.924 billion in spending for the 1997-1999 biennium, an
increase of $2.231 billion, or 11.8 percent, from 1995-1997 expenditures.
Resources for the 1997-1999 biennium were projected to be $21.946 billion,
including $1.630 billion carried forward from the previous biennium.

     The Legislature authorized 14.8 percent more spending for elementary and
secondary education spending in the 1997-1999 biennium than in 1995-1997, 17.6
percent more for health and human services, 12.5 percent more in local
government aids, 10.7 percent more for higher education, and 0.3 percent more
for all other expenditures. The Legislature set the General Fund budget reserve
at $522 million. The cash flow account was set at $350 million, and a property
tax reform reserve account of $46 million was created for future restructuring
of the property tax system. Other reserves totaled $72 million.

     After the Legislature adjourned its second special session in August 1997,
the Commissioner of Finance estimated that at June 30, 1999, the Accounting
General Fund balance would be positive $32 million. The Accounting General Fund
balance at June 30, 1997 was an estimated $861 million.


     The Commissioner of Finance, in a November 1997 forecast, estimated the
Accounting General Fund balance at June 30, 1999, at $1.360 billion, $1.328
billion more than estimated after the 1997 Legislature adjourned, due to a $729
million increase in projected revenues, a $256 million reduction in projected
expenditures, $21 million increase in dedicated reserves, and a $364 million
increase in the projected amount carried forward from the 1995-1997 biennium.
Higher than anticipated individual



                                       23

income tax payments were the major source of $272 million in additional
revenues in the first half of 1997, and human services savings were the
principal source of $92 million in reduced expenditures. The Commissioner
estimated the Accounting General Fund balance at June 30, 2001, at $1.284
billion.

     Only $453 million of the $1.360 billion projected 1997-1999 surplus was
available for spending. The statutes allocate the first $81 million of the
forecast balance to fund K-12 education tax credits and deductions enacted in
1997. Sixty percent of the remainder plus interest, $826 million, is added to a
property tax reform account.

     A February 1998 forecast projected an Accounting General Fund balance at
June 30, 1999, at $1.045 billion, due to a $507 million increase in projected
revenues, a $90 million decrease in expenditures, and a $5 million increase in
dedicated reserves. The balance at June 30, 2001, was projected at $2.137
billion.


     The 1998 Legislature increased spending $125 million for K-12 education
aids, $90 million to reduce the school property tax recognition shift
percentage to zero, $73 million for higher education, and $148 million for all
other operations. The Legislature also approved $999 million in capital
improvements, to be funded by $509 million in bonds and $502 million in
appropriations. The General Fund budget reserve was set at $622 million.


     After the Legislature adjourned in April 1998, the Commissioner of Finance
estimated the Accounting General Fund balance at June 30, 1999, at $35 million.



     The Commissioner of Finance, in a November 1998 forecast, estimated the
Accounting General Fund balance at June 30, 1999, at $953 million, due to an
$803 million increase in non-tobacco revenues, the receipt of $461 million in
tobacco settlement revenues, and a $262 million reduction in expenditures. A
total of $609 million of the $1.562 billion of estimated available revenues is
statutorily dedicated to reserves, tax reduction, and cash to replace bonding.

     The Commissioner of Finance in November 1998 estimated the balance at June
30, 2001, at $3.324 billion.

     A February 1999 forecast projected an Accounting General Fund balance at
June 30, 1999, at $1.235 billion due to a $285 million increase in projected
revenues and a $3 million increase in expenditures. The balance at June 30,
2001, was projected at $4.056 billion.

     The 1999 Legislature authorized $23.384 billion in spending for the
1999-2001 biennium, an increase of $2.053 billion, or 9.6%, from 1997-1999
expenditures. Resources for the 1999-2001 biennium were projected to be $24.620
billion. Revenues, excluding the balance brought forward from the 1997-1999
biennium, are expected to be $2.248 billion, or 10.8%, greater than the
previous biennium.

     The Legislature passed a $1.250 billion sales tax rebate. Individual
income tax rates were reduced in all three brackets, from 6.0% to 5.5%, from
8.0% to 7.25%, and from 8.5% to 8.0%. In addition, the "marriage penalty"
inherent in the previous rate structure was eliminated. These changes reduced
projected revenues by $1.312 billion for the 1999-2001 biennium.

     The Legislature authorized 15.7% more spending for elementary and
secondary education in the 1999-2001 biennium than in 1997-1999, 21.6% more for
property tax aid programs to local governments, 12.2% more for health and human
services and 7.0% more for higher education.

     The Legislature also provided that if, based on a forecast of general fund
revenues and expenditures in November of an even-numbered year or February of
an odd-numbered year, the Commissioner of Finance projects a positive
unrestricted budgetary general fund balance at the close of the biennium that
exceeds one-half of one percent of total general fund biennial revenues, the
Commissioner shall designate the entire balance as available for rebate to
taxpayers. In making the determinations of general fund balance or biennial
revenue, the Commissioner is prohibited from including any balance or revenue
attributable to certain tobacco settlement payments received after July 1, 1998
and before July 1, 2001. If the Commissioner designates an amount for rebate,
the Governor must then present a



                                       24
<PAGE>


plan to the Minnesota Legislature for rebating that amount, with payments to
begin no later than August 15 of the odd-numbered year. The legislation
provides that the Legislature shall either enact, modify or reject the plan
presented by the Governor.

     After the Legislature adjourned in May 1999, the Commissioner of Finance
estimated that at June 30, 2001, the Accounting General Fund balance would be
positive $80 million. The Accounting General Fund balance at June 30, 1999, was
an estimated $1.518 billion.

     The Commissioner of Finance, in a November 1999 forecast, estimated the
Accounting General Fund balance at June 30, 2001, at $1.584 billion, $1.504
billion more than estimated after the 1999 Legislature adjourned, due to a
$1.154 billion increase in projected revenues, a $453 million gain from the
1997-1999 biennium, and a $103 million decrease caused by spending increases
and other changes.

     Only $571 million of the $1.584 billion projected 1999-2001 surplus was
available for spending. The statutes allocate $43 million to provide a $50
increase in per pupil elementary and secondary school aids. Sixty percent of
the remaining balance plus interest, $1.013 billion, is deposited into the
Property Tax Reform Account.


     The State of Minnesota has no obligation to pay any bonds of its political
or governmental subdivisions, municipalities, governmental agencies, or
instrumentalities. The creditworthiness of local general obligation bonds is
dependent upon the financial condition of the local government issuer, and the
creditworthiness of revenue bonds is dependent upon the availability of
particular designated revenue sources or the financial conditions of the
underlying obligors. Although most of the bonds owned by the Minnesota Series
are expected to be obligations other than general obligations of the State of
Minnesota itself, there can be no assurance that the same factors that
adversely affect the economy of the State generally will not also affect
adversely the market value or marketability of such other obligations, or the
ability of the obligors to pay the principal of or interest on such
obligations.


     At the local level, the property tax base has recovered after its growth
was slowed in many communities in the early 1990s by an overcapacity in certain
segments of the commercial real estate market. Local finances are also affected
by the amount of State aid that is made available. Further, various of the
issuers within the State of Minnesota, as well as the State of Minnesota
itself, whose securities may be purchased by the Minnesota Series, may now or
in the future be subject to lawsuits involving material amounts. It is
impossible to predict the outcome of these lawsuits. Any losses with respect to
these lawsuits may have an adverse impact on the ability of these issuers to
meet their obligations.

     The Department of Finance acknowledged in 1995 that the State of
Minnesota's accounting system was not Year 2000 (Y2K) compliant and that the
systems vendor would deliver a compliant version upgrade in the future. In
mid-1997, State of Minnesota technical staff, along with the systems vendor,
began a $6.5 million project to install the new compliant version of the
accounting software. The State of Minnesota implemented the new software
version on November 30, 1998. Testing of the new compliant version to date has
been very positive. Even if the State of Minnesota successfully addresses its
Year 2000 compliance, there can be no assurance that any other organization or
governmental agency with which the State of Minnesota electronically interacts,
including vendors and the federal government, will be Year 2000 compliant. In
the event of any such occurrences, the State of Minnesota may face material
adverse consequences with respect to its revenues and operations. Local issuers
in the State of Minnesota may face similar problems.

     Legislation enacted in 1995 provides that it is the intent of the
Minnesota Legislature that interest income on obligations of Minnesota
governmental units, and exempt-interest dividends that are derived from
interest income on such obligations, be included for Minnesota income tax
purposes in the net income of individuals, estates and trusts, if it is
judicially determined that the exemption by Minnesota of such interest or such
exempt-interest dividends unlawfully discriminates against interstate commerce
because interest income on obligations of governmental issuers located in other
states, or exempt-interest dividends derived from such obligations, is so
included. This provision provides that it applies to taxable years that begin
during or after the calendar year in which such judicial decision becomes
final,



                                       25
<PAGE>


regardless of the date on which the obligations were issued, and that other
remedies apply for previous taxable years. The United States Supreme Court in
1995 denied certiorari in a case in which an Ohio State Court upheld an
exemption for interest income on obligations of Ohio governmental issuers, even
though interest income on obligations of non-Ohio governmental issuers was
subject to tax. In 1997, the United States Supreme Court denied certiorari in a
subsequent case from Ohio involving the same taxpayer and the same issue, in
which the Ohio Supreme Court refused to reconsider the merits of the case on
the ground that the previous final state court judgment barred any claim
arising out of the transaction that was the subject of the previous action. It
cannot be predicted whether a similar case will be brought in Minnesota or
elsewhere, or what the outcome of such case would be. Should an adverse
decision be rendered, the value of the securities purchased by the Minnesota
Series might be adversely affected, and the value of the shares of the
Minnesota Series might also be adversely affected.

     The State's bond ratings in August, 1999 were Aaa by Moody's, AAA by S&P,
and AAA by Fitch's. Economic difficulties and the resultant impact on State and
local government finances may adversely affect the market value of obligations
in the portfolio of the Minnesota Series or the ability of respective obligors
to make timely payment of the principal and interest on such obligations.


     THE NEW JERSEY SERIES -- SPECIAL INVESTMENT CONSIDERATIONS. The portfolio
of the New Jersey Series contains different issues of debt obligations issued
by or on behalf of the State of New Jersey and counties, municipalities and
other political subdivisions and other public authorities thereof or by the
Government of Puerto Rico or the Government of Guam or by their respective
authorities. Investment in the New Jersey Series should be made with an
understanding that the value of the underlying Portfolio may decline with
increases in interest rates. Prospective investors should consider the recent
financial difficulties and pressures which the State of New Jersey and certain
of its public authorities have undergone.

     The New Jersey State Constitution prohibits the legislature from making
appropriations in any fiscal year in excess of the total revenue on hand and
anticipated. A debt or liability that exceeds 1% of total appropriations for
the year is also prohibited, unless it is in connection with a refinancing to
produce a debt service savings or it is approved at a general election. Such
debt must be authorized by law and applied to a single specified object or
work. These Constitutional provisions do not apply to debt incurred because of
war, insurrection or emergencies caused by disaster.

     Pursuant to Article VIII, Section II, par. 2 of the New Jersey
Constitution, no monies may be drawn from the State Treasury except for
appropriations made by law. In addition, the monies for the support of State
government and all State purposes, as far as can be ascertained, must be
provided for in one general appropriation law covering one and the same fiscal
year.

     In addition to the Constitutional provisions, the New Jersey statutes
contain provisions concerning the budget and appropriation system. Under these
provisions, each unit of the State requests an appropriation from the Director
of the Division of Budget and Accounting, who reviews the budget requests and
forwards them with her recommendations to the Governor. The Governor then
transmits a recommended expenditures and sources of anticipated revenue to the
legislature, which reviews the Governor's Budget Message and submits an
appropriation bill to the Governor for her signature by July 1 of each year. At
the time of signing the bill, the Governor may revise appropriations or
anticipated revenues. That action can be reversed by a two-thirds vote of each
House. No supplemental appropriation may be enacted after adoption of the act,
except where there are sufficient revenues on hand or anticipated, as certified
by the Governor, to meet the appropriation. Finally, the Governor may, during
the course of the year, prevent the expenditure of various appropriations when
revenues are below those anticipated or when any such expenditure is determined
not to be in the best interest of the State.

     Reflecting the economic downturn recently affecting the Northeast, the
rate of unemployment in the State rose from a low of 3.6 percent during the
first quarter of 1989 to a recessionary peak of 8.5% during 1992. Since then,
the unemployment rate fell to an average of 6.2% in 1996 and then from 5.7% in
November 1997 to 4.4% in January, 1998 and 4.2% in November 1998.


                                       26

     Earnings of workers employed in New Jersey rose from $162,701,773,000 in
1996 to $171,766,782,000 in 1997, an increase of 5.6%. The largest industries
in 1997 based on earnings percentage were services (30.7% of earnings), state
and local government (11.8%) and manufacture of nondurable goods (10.0%). New
Jersey's total personal income of $259,566,754,000 in 1997 ranked 8th in the
United States, representing a 5% increase from 1996. New Jersey's 1997 per
capita income of $32,233 ranked 3rd in the United States, representing an
increase of 4.3% from 1996.

     After an average annual manufacturing job loss of 33,500 from 1989 through
1992, New Jersey's factory job losses fell to 13,300 and 7,300 during 1993 and
1994 respectively. During 1995 and 1996, however, manufacturing job losses
increased to 10,100 and 13,900. However, according to information from the
Bureau of Labor Statistics, only 9,200 manufacturing jobs, or 1.89%, were lost
from November, 1997 to November, 1998. Over the same period, construction jobs
increased by 5.03%; transportation and public utilities by 1.79%; trade by
1.98%; finance, insurance and real estate by 2.37%; and services by 3.31%.
Employment in government decreased slightly over this period. Total job growth
peaked in 1997 at 87,000, up from a recent average of 50,000 a year. Total jobs
increased by 65,100 from November, 1997 to November, 1998 or 1.72%. The Rutgers
Economic Advisory Service has predicted that 76,400 new jobs will be created in
1999 with most positions in the service and retail sectors and in
communications.

     According to a report issued by the Federal Reserve Board in December,
1998 (the "Beige Book"), housing permits surged in October, 1998 led by a wave
of multifamily projects in Northern New Jersey. At the same time, moreover, New
Jersey homebuilders were reporting fairly strong recent traffic and sales. Most
office building construction forecast for the next two years is expected to be
built in central New Jersey according to a survey by the New Jersey Chapter of
the National Association of Industrial and Office Properties. Eighty-five
percent of $1.62 billion is expected to be spent on new office and industrial
sites in Monmouth, Middlesex, Somerset, Morris and Mercer Counties, and
two-thirds of $1.62 billion will be spent in Morris and Mercer alone. However,
total construction spending projections for 1999 and 2000 of $14.1 billion
represent a 9.6% drop from $15.6 billion forecast a year ago for 1998 and 1999.

     Based on estimates released by the United States Census Bureau, New
Jersey's estimated population grew from 8,058,384 to 8,115,011 in the 12-month
period ending July 1, 1998, an increase of 0.7%. This compares with an increase
of 0.2% for New York and a decrease of -0.1% for Pennsylvania over the same
period. The relatively small New Jersey increase, compared to a national
increase of 1%, overlays a significant population shift within the State from
northeastern industrial areas towards the coast and central New Jersey.

     The State's 1999 Fiscal Year budget became law on June 30, 1998. Of the
$18,123.8 million appropriated in Fiscal Year 1999 from the General Fund, the
Property Tax Relief Fund, the Gubernatorial Elections Fund, the Casino Control
Fund and the Casino Revenue Fund, the following appropriations were made for
the following purposes: (i) $7,455.1 million (41.1%) for State Aid to Local
Governments ("State Aid"), (ii) $4,898.8 million (27.0%) for Grants-in-Aid,
(iii) $4,653.2 million (25.7%) for Direct State Services, (iv) $501.1 million
(2.8%) for Debt Service on State general obligation bonds and (v) $615.6
million (3.7%) for Capital Construction.

     The largest recommended appropriation included in the State Aid category,
in the amount of $5,925.6 million, was for elementary and secondary education
programs including $2,747.6 million for core curriculum standards, $302.5
million for early childhood aid, $249.8 million for Abbott v. Burke Parity
Remedy aid (see litigation discussion below), $261.1 million for pupil
transportation aid, $647.9 million for special education, $82.7 million for
nonpublic school aid and $95.1 million for debt service on school bonds. Also,
a State Aid appropriation of $50.0 million for facilities improvements was
funded from a portion of an increase in State cigarette taxes. Additional
significant appropriations for schools included $157 million for supplemental
core curriculum standards aid, $187.3 million for demonstrably effective
program aid and $917.4 million to assist school districts with their
contributory share of the social security and teachers' pensions and benefits
programs.

     Other recommended appropriations in the State Aid category included $836.6
million for the Department of Community Affairs, $756.1 million for
Consolidated Municipal Property Tax Relief,


                                       27

$16.7 million for housing programs, $33.0 million for block grant programs,
$30.0 million for discretionary aid, $252.7 million for welfare programs, $80.3
million for county mental hospitals, $50.0 million for matching funds to local
governments for open space preservation. State Aid appropriations to the
Department of Treasury of $228.7 million were used for aid to county colleges
($159.8 million); the cost of property tax deductions and exemptions for senior
citizens, disabled persons and veterans ($53.6 million); and the State
contribution to the Consolidated Police and Firemen's Pension Fund ($9.3
million).

     The second largest category of appropriations, after State Aid ($4,898.8
million), was for Grants-in-Aid. This category represents amounts used for
payments to individuals or to public or private agencies for benefits or
services to which a recipient is by law entitled. The third largest category
($4,653.2 million) was for Direct State Services consisting of amounts used to
support the operation of State government departments, the Executive office,
various State commissions and the State legislature and judiciary. Finally,
smaller amounts were appropriated to pay debt service on general obligation
bonds of the State ($501.1 million) and for capital construction financed on a
pay-as-you go basis ($615.6 million).

     At any given time, there are various claims and cases pending against the
State and State agencies and employees, seeking recovery of monetary damages
that are primarily paid out of the fund created pursuant to the Tort Claims
Act, N.J.S.A. 59:1-1 et seq. Such claims include but are not limited to those
that may be filed against the University of Medicine and Dentistry and its
employees seeking recoveries for alleged medical malpractice. In addition, at
any given time there are various contract and other claims against the State,
among other parties, including environmental claims arising from the alleged
disposal of hazardous wastes, seeking recovery of monetary damages. The State
is unable to estimate its exposure for these claims and cases. An independent
study estimated an aggregate potential exposure of $85,300,000 for tort and
medical malpractice claims pending, as of December 31, 1997. Moreover, New
Jersey is involved in a number of other lawsuits in which adverse decisions
could materially affect revenue or expenditures.

     Such lawsuits include (1) actions challenging assessments made upon
property and casualty liability insurers doing business in New Jersey pursuant
to the Fair Automobile Insurance Reform Act; (2) a suit challenging the
constitutionality on Federal Commerce Clause grounds, of certain hazardous and
solid waste licensure renewal fees collected by the Department of Environmental
Protection; (3) litigation seeking to extend to middle income and poor rural
school districts the mandate of Abbott v. Burke, which requires poor urban
school districts to be provided amounts sufficient to permit them to spend at
the average of wealthy suburban school districts; (4) a class action
challenging the treatment of prisoners with serious mental disorders confined
within the State Department of Corrections system; (5) two separate suits
alleging violation of environmental laws resulting from alleged contamination
existing at the State-owned Liberty State Park and from certain soil shipments
made to that Park in connection with the I-287 wetlands mitigation project; (6)
an action challenging the State's application of the "spousal impoverishment
provisions" of the Medicare Catastrophic Coverage Act governing the treatment
of income and resources available to the "community" spouse when an
institutionalized spouse seeks to establish Medicare eligibility; (7) a
challenge by 18 New Jersey hospitals to the State's Medicaid reimbursement
procedures; (8) a series of challenges to the construction and issuance of
bonds to construct an Atlantic City road and tunnel project including
challenges based on alleged violations of (i) State constitutional provisions
limiting the use of certain revenues, (ii) federal securities law disclosure
requirements and (iii) certain federal and State environmental requirements;
(9) a breach of contract and civil rights action brought against the State by
Medicare part B service providers who seek reimbursement for Medicare
co-insurance and deductibles not paid by the State Medicaid program from 1988
to February 10, 1995; (10) a suit brought by a private resource recovery
facility owner and operator against the State Department of Environmental
Protection and others, including the Camden County Pollution Control Financing
Authority ("CCPCFA"), seeking a halt to the County's solid waste reprocurement
process pending clarification of bid specifications with a cross claim against
the State brought by CCPCFA; (11) a challenge on State constitutional grounds
to the "family cap" provisions of the State Work First New Jersey Act brought
on behalf of all persons who did not receive an increase in


                                       28
<PAGE>

certain welfare benefits because of the cap; and (12) a challenge to a State
contract award made for the procurement of an enhanced motor vehicle inspection
system which, if system implementation is delayed, may expose the State to
significant federal sanctions including loss of federal transportation funds
and imposition of stricter air pollution standards.

     Year 2000. Beginning in 1997, the State required all State departments to
develop three year action plans identifying all impacts expected from the "Year
2000" problem potentially affecting computer operations as that year draws
near. External parties have been requested to provide similar plans. Testing,
validation and implementation of critical centrally maintained systems was 55%
complete as of June 30, 1998. As of that date, the State had incurred expenses
of approximately $55 million of $132 million estimated to be needed to achieve
Year 2000 compliance.

     As of January 1999, the State's general obligation bonds were rated AA+ by
S&P and Fitch and Aa1 by Moody's.

     THE NEW YORK SERIES -- SPECIAL INVESTMENT CONSIDERATIONS. Since the New
York Series concentrates its investments in New York tax-exempt securities, the
Fund is significantly affected by any political, economic or regulatory
developments affecting the ability of New York tax-exempt issuers to pay
interest or repay principal. Investors should be aware that certain issuers of
New York tax-exempt securities have experienced serious financial difficulties
in recent years. A reoccurrence of these difficulties may impair the ability of
certain New York issuers to maintain debt service on their obligations.

     The fiscal stability of New York State is related to the fiscal stability
of the State's municipalities, its Agencies and Authorities (which generally
finance, construct and operate revenue-producing public benefit facilities).
This is due in part to the fact that Agencies, Authorities and local
governments in financial trouble often seek State financial assistance. The
experience has been that if New York City or any of the Agencies or Authorities
suffers serious financial difficulty, both the ability of the State, the City,
the State's political subdivisions, the Agencies and the Authorities to obtain
financing in the public credit markets and the market price of outstanding New
York tax-exempt securities are adversely affected.

     Over the long term, the State and City face potential economic problems.
The City accounts for a large portion of the State's population and personal
income, and the City's financial health affects the State in numerous ways. The
City continues to require significant financial assistance from the State. The
City depends on State aid both to enable the City to balance its budget and to
meet its cash requirements. The State could also be affected by the ability of
the City to market its securities successfully in the public credit markets.

     The economic and financial condition of the State also may be affected by
various financial, social, economic and political factors. Such factors can be
very complex, may vary from fiscal year to fiscal year and are frequently the
result of actions taken not only by the State and its agencies and
instrumentalities, but also by entities, such as the Federal government, that
are not under the control of the State.


     The following summary information on risk factors in concentrating in New
York municipal obligations is based on the State's Annual Information
Statement, dated August 24, 1999, as supplemented on October 20, 1999, and on
publicly available official statements relating to offerings of the City of
municipal securities on or prior to November 3, 1999, and it does not purport
to be a complete description of the considerations contained therein. No
representation is made as to the accuracy of such information.


     During the mid-1970's, New York State, some of its agencies,
instrumentalities and public benefit corporations, and certain of its
municipalities faced serious financial difficulties. To address many of these
financial problems, the State developed various programs, many of which were
successful in ameliorating the financial crisis. Any further financial problems
experienced by these Authorities or municipalities could have a direct adverse
effect on the New York Municipal Obligations in which the Fund invests.

     New York City. The national economic downturn which began in July 1990
adversely affected the local economy, which had been declining since late 1989.
As a result, New York City experienced job


                                       29

losses in 1990 and 1991 and real Gross City Product (GCP) fell in those two
years. For the 1992 fiscal year, the City closed a projected budget gap of $3.3
billion in order to achieve a balanced budget as required by the laws of the
State. Beginning in 1992, the improvement in the national economy helped
stabilize conditions in the City. Employment losses moderated toward year-end
and real GCP increased, boosted by strong wage gains. After noticeable
improvements in the City's economy during calendar year 1994, economic growth
slowed in 1995 and thereafter improved commencing in calendar year 1996,
reflecting improved securities industry earnings and employment in other
sectors. Overall, the City's economic improvement accelerated significantly in
1997 and 1998. Much of the increase can be traced to the performance of the
securities industry, but the City's economy also produced gains in the retail
trade sector, the hotel and tourism industry, and business services, with
private sector employment higher than previously forecasted. The City's current
financial plan assumes that, after strong growth in 1998-1999, moderate
economic growth will exist through calendar year 2003, with moderate job growth
and wage increases.

     For each of the 1981 through 1999 fiscal years, the City had an operating
surplus, before discretionary and other transfers, and achieved balanced
operating results as reported in accordance with then applicable generally
accepted accounting principles ("GAAP") after discretionary and other
transfers. The City has been required to close substantial gaps between
forecast revenues and forecast expenditures in order to maintain balanced
operating results. There can be no assurance that the City will continue to
maintain balanced operating results as required by State law without tax or
other revenue increases or reductions in City services or entitlement programs,
which could adversely affect the City's economic base.

     2000-2003 New York City Financial Plan. The Mayor is responsible for
preparing the City's four-year financial plan including the current financial
plan for the 2000 through 2003 fiscal years (the "2000-2003 Financial Plan,"
the "Financial Plan" or "City Plan").

     The Financial Plan projects revenues and expenditures for the 2000 fiscal
year balanced in accordance with GAAP and projects gaps of $1.8 billion, $1.9
billion and $1.8 billion for the years 2001 through 2003, respectively. The
Financial Plan takes into account an increase in projected tax revenues in
fiscal years 2000 through 2003; projected resources in fiscal years 2000
through 2003, respectively, from the receipt by the City of funds from the
settlement of litigation with the leading cigarette companies; a reduction in
the assumed collection of projected rent payments for the City's airports and a
delay in the receipt of such payments from fiscal year 2000 to fiscal year
2001; net increases in spending in fiscal years 2000 through 2003, including
spending for Medicaid, education initiatives, anti-smoking programs, employee
fringe benefit costs, and other agency programs. In addition, the Financial
Plan includes a proposed discretionary transfer in fiscal year 2000 to pay debt
service due in fiscal year 2001 totaling $429 million, and a proposed
discretionary transfer in fiscal year 2001 to pay debt service due in fiscal
year 2002 totaling $345 million.

     The Financial Plan is based on numerous assumptions, including the
condition of the City's and the region's economies and modest employment growth
and the concomitant receipt of economically sensitive tax revenues in the
amounts projected. The Financial Plan is subject to various other uncertainties
and contingencies relating to, among other factors, the extent, if any, to
which wage increases for City employees exceed the annual wage costs assumed
for the 2000 through 2003 fiscal years; continuation of projected interest
earnings assumptions for pension fund assets and current assumptions with
respect to wages for City employees affecting the City's required pension fund
contributions; the willingness and ability of the State to provide the aid
contemplated by the Financial Plan and to take various other actions to assist
the City; the ability of the Health and Hospitals Corporation, the Board of
Education and other such agencies to maintain balanced budgets; the willingness
of the Federal government to provide the amount of Federal aid contemplated in
the Financial Plan; the impact on City revenues and expenditures of Federal and
State welfare reform and any future legislation affecting Medicare or other
entitlement programs; adoption of the City's budgets by the City Council in
substantially the forms submitted by the Mayor; the ability of the City to
implement cost reduction initiatives, and the success with which the City
controls expenditures; the impact of conditions in the real estate market on
real estate tax revenues; the City's ability to market its securities
successfully in the public credit markets; and unanticipated expenditures that
may be incurred as a result of the need to maintain the City's infrastructure.


                                       30

     On July 14, 1999, the City Comptroller issued a report which projected a
surplus for fiscal year 2000 of between $223 million and $891 million. In
addition, the report projected budget gaps of between $1.8 billion and $3.5
billion, $1.7 billion and $3.6 billion, and $1.7 billion and $4.1 billion in
fiscal years 2001 through 2003, respectively. The report further noted that the
City Comptroller's forecast is contingent on the continued growth of the City
economy and that the fear of renewed inflationary pressures has created
uncertainty in the bond market which may dampen economic growth in the future.

     The City depends on aid from the State both to enable the City to balance
its budget and to meet its cash requirements. There can be no assurance that
there will not be reductions in State aid to the City from amounts currently
projected; that, in future years, State budgets will be adopted by the April 1
statutory deadline, or interim appropriations will be enacted; or that any such
reductions or delays will not have adverse effects on the City's cash flow or
expenditures. In addition, the Federal budget negotiation process could result
in a reduction or a delay in the receipt of Federal grants which could have
additional adverse effects on the City's cash flow or revenues.


     The City's projections set forth in the City Plan are based on various
assumptions and contingencies which are uncertain and which may not
materialize.


     Implementation of the Financial Plan is also dependent upon the City's
ability to market its securities successfully. The City's financing program for
fiscal years 2000 through 2003 contemplates the issuance of $7.449 billion of
general obligation bonds and $3.35 billion of bonds to be issued by the New
York City Transitional Finance Authority (the "Finance Authority"). In
addition, the City Plan anticipates access to approximately $2.4 billion in
financing capacity of TSASC, Inc. ("TSASC"), which will issue debt secured by
revenues derived from the settlement of litigation with tobacco companies
selling cigarettes in the United States. The Finance Authority and TSASC were
created to assist the City in financing its capital program while keeping the
City's indebtedness within the forecast level of the constitutional
restrictions on the amount of debt the City is authorized to incur. In
addition, the City issues revenue and tax anticipation notes to finance its
seasonal working capital requirements. The success of projected public sales of
City, New York City Municipal Water Finance Authority (the "Water Authority"),
Finance Authority, TSASC and other bonds and notes will be subject to
prevailing market conditions. The City's planned capital and operating
expenditures are dependent upon the sale of its general obligation debt, as
well as debt of the Water Authority, Finance Authority and TSASC. Future
developments concerning the City and public discussion of such developments, as
well as prevailing market conditions, may affect the market for outstanding
City general obligation bonds and notes.

     The City Comptroller and other agencies and public officials, from time to
time, issue reports and make public statements which, among other things, state
that projected revenues and expenditures may be different from those forecasted
in the City Plan.

     Ratings. Moody's, S&P and Fitch IBCA, Inc. ("Fitch") currently rate the
City's outstanding general obligation bonds A3, A- and A, respectively. Such
ratings reflect only the views of Moody's, S&P and Fitch from which an
explanation of the significance of such ratings may be obtained. There is no
assurance that such ratings will continue for any given period of time or that
they will not be revised downward or withdrawn entirely. Any such downward
revision or withdrawal could have an adverse effect on the market prices of the
bonds. On July 10, 1995, S&P revised its rating of City bonds downward to BBB+.
On July 16, 1998, S&P revised its rating of City bonds upward to A-. Moody's
rating of City bonds was revised in February 1998 to A3 from Baa1. On March 8,
1999, Fitch revised its rating of City bonds upward to A.

     Outstanding Net Indebtedness. As of September 30, 1999, the City and the
Municipal Assistance Corporation for the City of New York had, respectively,
$26.315 billion and $2.846 billion of outstanding net long-term debt.

     Litigation. The City is a defendant in lawsuits pertaining to material
matters, including claims asserted which are incidental to performing routine
governmental and other functions. This litigation includes, but is not limited
to, actions commenced and claims asserted against the City arising out of
alleged constitutional violations, torts, breaches of contracts, and other
violations of law and condem-



                                       31

nation proceedings. While the ultimate outcome and fiscal impact, if any, of
the proceedings and claims brought against the City are not currently
predictable, adverse determinations in certain of them might have a material
adverse effect upon the City's ability to carry out the Financial Plan. The
Financial Plan includes provisions for judgments and claims of $393 million,
$407 million, $429 million and $448  million for the 2000 through 2003 fiscal
years, respectively. The City has estimated that its potential future liability
on account of outstanding claims against it as of June 30, 1999 amounted to
approximately $3.5 billion.

     New York State. Recent Developments. The national economy has maintained a
robust rate of growth during the past six quarters as the expansion, which is
well into its ninth year, continues. The national expansion, if it continues
through February 2000, will be the longest on record. Since early 1992,
approximately 19 million jobs have been added nationally. Output growth has
averaged 3.2 percent over this period, essentially the same as the 3.3 percent
average annual growth during the post-World War II period. The State economy
has also continued to expand, with over 600,000 jobs added since late 1992.
Employment growth has been slower than in the nation during this period,
although the State's relative performance has improved in the last two years.
Growth in average wages in New York has generally outperformed the nation,
while growth in personal income per capita has kept pace with the nation.

     The forecast for continued growth, and any resultant impact on the
1999-2000 New York State Financial Plan (the "State Plan"), contains some
uncertainties. Stronger-than-expected gains in employment and wages could lead
to unanticipated strong growth in consumer spending. Also, improvements in
foreign economies may be weaker than expected and therefore, may have
unanticipated effects on the domestic economy. The inflation rate may differ
significantly from expectations due to the conflicting impacts of a tight labor
market and improved productivity growth as well as to the future direction and
magnitude of fluctuations of oil prices. In addition, the State economic
forecast could over- or under-estimate the level of future bonus payments,
financial sector profits or inflation growth, resulting in unexpected economic
impacts. Similarly, the State forecast could fail to correctly estimate the
amount of employment change in the banking, financial and other business
service sectors as well as the direction of employment change that is likely to
accompany telecommunications and energy deregulation.

     The 1999-2000 Fiscal Year. The 1999-2000 Financial Plan projects a closing
balance of $2.85 billion in the General Fund. Total receipts and transfers from
other funds are projected to reach $39.31 billion, an increase of over $2.57
billion from the prior fiscal year, and disbursements and transfers to other
funds are projected to be $37.36 billion, an increase of $868 million from the
total disbursed in the prior fiscal year.

     Projections of total State receipts in the State Plan are based on the
State tax structure in effect during the fiscal year and on assumptions
relating to basic economic factors and their historical relationships to State
tax receipts. In preparing projections of State receipts, economic forecasts
relating to personal income, wages, consumption, profits and employment have
been particularly important. The projection of receipts from most tax or
revenue sources is generally made by estimating the change in yield of such tax
or revenue source caused by economic and other factors, rather than by
estimating the total yield of such tax or revenue source from its estimated tax
base. The forecasting methodology, however, ensures that State fiscal year
collection estimates for taxes that are based on a computation of annual
liability, such as the business and personal income taxes, are consistent with
estimates of total liability under such taxes.

     Projections of total State disbursements are based on assumptions relating
to economic and demographic factors, potential collective bargaining
agreements, levels of disbursements for various services provided by local
governments (where the cost is partially reimbursed by the State), and the
results of various administrative and statutory mechanisms in controlling
disbursements for State operations. Factors that may affect the level of
disbursements in the fiscal year include uncertainties relating to the economy
of the nation and the State, the policies of the federal government, collective
bargaining negotiations and changes in the demand for and use of State
services.



                                       32
<PAGE>



     Despite recent budgetary surpluses recorded by the State, actions
affecting the level of receipts and disbursements, the relative strength of the
State and regional economy, and actions by the federal government could impact
projected budget gaps for the State. These gaps would result from a disparity
between recurring revenues and the costs of increasing the level of support for
State programs. For example, the fiscal effects of tax reductions adopted in
the last several fiscal years are projected to grow more substantially in the
forecast period, continuing to restrain receipts levels and placing pressure on
future spending levels. To address a potential imbalance in any given fiscal
year, the State would be required to take actions to increase receipts and/or
reduce disbursements as it enacts the budget for that year, and under the State
Constitution, the Governor is required to propose a balanced budget each year.
There can be no assurance, however, that the Legislature will enact the
Governor's proposals or that the State's actions will be sufficient to preserve
budgetary balance in a given fiscal year or to align recurring receipts and
disbursements in future fiscal years.

     New York Local Government Assistance Corporation. In 1990, as part of a
State fiscal reform program, legislation was enacted creating the New York Loan
Government Assistance Corporation ("LGAC"), a public benefit corporation
empowered to issue long-term obligations to fund certain payments to local
governments traditionally funded through the State's annual seasonal borrowing.
The legislation empowered LGAC to issue bonds and notes in an amount to yield
net proceeds not in excess of $4.7 billion (exclusive of certain refunding
bonds). Over a period of years, the issuance of those long-term obligations,
which will be amortized over no more than 30 years, is expected to result in
eliminating the need for continued short-term seasonal borrowing. The
legislation also dedicated revenues equal to one percent of the four percent
State sales and use tax to pay debt service on these bonds. The legislation
also imposed a cap on the annual seasonal borrowing of the State at $4.7
billion, less net proceeds of bonds issued by LGAC and bonds issued to provide
for capitalized interest, except in cases where the Governor and the
legislative leaders have certified both the need for additional borrowing and
provided a schedule for reducing it to the cap. If borrowing above the cap is
thus permitted in any fiscal year, it is required by law to be reduced to the
cap by the fourth fiscal year after the limit was first exceeded. This
provision capping the seasonal borrowing was included as a covenant with LGAC's
bondholders in the resolution authorizing such bonds.

     As of June 1995, LGAC had issued bonds and notes to provide net proceeds
of $4.7 billion, completing the program. The impact of LGAC's borrowings, as
well as other changes in revenue and spending patterns, is that the State has
been able to meet its cash flow needs throughout the fiscal year without
relying on short-term seasonal borrowings.


     Composition of State Cash Governmental Funds Group. Substantially all
State non-pension financial operations are accounted for in the State's
governmental funds group. Governmental funds include: (i) the General Fund,
which receives all income not required by law to be deposited in another fund;
(ii) Special Revenue Funds, which receive the preponderance of moneys received
by the State from the Federal government and other income the use of which is
legally restricted to certain purposes; (iii) Capital Projects Funds, used to
finance the acquisition and construction of major capital facilities by the
State and to aid in certain of such projects conducted by local governments or
public authorities; and (iv) Debt Service Funds, which are used for the
accumulation of moneys for the payment of principal of and interest on
long-term debt and to meet lease-purchase and other contractual-obligation
commitments.


     Authorities. The fiscal stability of the State is related to the fiscal
stability of its public Authorities. Authorities have various responsibilities,
including those which finance, construct and/or operate revenue-producing
public facilities. Authorities are not subject to the constitutional
restrictions on the incurrence of debt which apply to the State itself, and may
issue bonds and notes within the amounts and restrictions set forth in their
legislative authorization. As of December 31, 1998, there were 17 Authorities
that had outstanding debt of $100 million or more and the aggregate outstanding
debt, including refunding bonds, of all Authorities was $94 billion, only a
portion of which constitutes State-supported or State-related debt.

     Authorities generally pay their operating expenses and debt service costs
from revenues generated by the projects they finance or operate, such as tolls
charged for use of highways, bridges or tunnels,




                                       33
<PAGE>

charges for electric power, electric and gas utility services, rentals charged
for housing units and charges for occupancy at medical care facilities. In
addition, State legislation authorizes several financing techniques for
Authorities. Also, there are statutory arrangements providing for State local
assistance payments otherwise payable to localities to be made under certain
circumstances to Authorities. Although the State has no obligation to provide
additional assistance to localities whose local assistance payments have been
paid to Authorities under these arrangements, if local assistance payments are
diverted the affected localities could seek additional State assistance. Some
Authorities also receive moneys from State appropriations to pay for the
operating costs of certain of their programs.

     Ratings. S&P rates the State's general obligation bonds A, and Moody's
rates the State's general obligation bonds A2. Ratings reflect only the
respective views of such organizations, and an explanation of the significance
of such ratings must be obtained from the rating agency furnishing the same.
There is no assurance that a particular rating will continue for any given
period of time or that any such rating will not be revised downward or
withdrawn entirely if, in the judgment of the agency originally establishing
the rating, circumstances so warrant. A downward revision or withdrawal of such
ratings, or either of them, may have an effect on the market price of the State
Municipal Obligations in which the New York Series invests.


     General Obligation Debt. As of March 31, 1999, the State had outstanding
approximately $4.8 billion in general obligation bonds, including $185 million
in bond anticipation notes outstanding. Principal and interest due on general
obligation bonds and interest due on bond anticipation notes were $748.2
million for the 1998-99 fiscal year and are estimated to be $730.7 million for
the State's 1999-2000 fiscal year.

     Litigation. The State is a defendant in numerous legal proceedings
pertaining to matters incidental to the performance of routine governmental
operations. Such litigation includes, but is not limited to, claims asserted
against the State arising from alleged torts, alleged breaches of contracts,
condemnation proceedings, miscellaneous civil rights cases and other alleged
violations of State and Federal laws. These proceedings could affect adversely
the financial condition of the State in the 1999-2000 fiscal year or
thereafter.

     The State believes that the State Plan includes sufficient reserves for
the payment of judgments that may be required during the 1999-2000 fiscal year.
There can be no assurance, however, that an adverse decision in any of these
proceedings would not exceed the amount of all potential State Plan reserves
available for the payment of judgments and, therefore, could affect the ability
of the State to maintain a balanced 1999-2000 State Plan. The General Purpose
Financial Statements for the 1998-1999 fiscal year report estimated probable
awarded and anticipated unfavorable judgments of $895 million, of which $132
million is expected to be paid during the 1999-2000 fiscal year.

     In addition, the State is party to other claims and litigation which its
legal counsel has advised are not probable of adverse court decisions or are
not deemed adverse and material. Although the amounts of potential losses
resulting from this litigation, if any, are not presently determinable, it is
the State's opinion that its ultimate liability in these cases is not expected
to have a material adverse effect on the State's financial position in the
1999-2000 fiscal year or thereafter.

     Other Localities. Certain localities outside the City have experienced
financial problems and have requested and received additional State assistance
during the last several State fiscal years. The potential impact on the State
of any future requests by localities for additional oversight and financial
assistance is not included in the projections of the State receipts and
disbursements in the State's 1999-2000 fiscal year.

     THE OHIO SERIES -- SPECIAL INVESTMENT CONSIDERATIONS. Although
manufacturing (including auto-related manufacturing) in Ohio remains an
important part of the State's economy, the greatest growth in employment in
Ohio in recent years, consistent with national trends, has been in the
non-manufacturing area. Ohio ranked third in the nation in 1997 gross state
product derived from manufacturing. Manufacturing was 26% of Ohio's gross state
product compared to 18% of that total being from "services". As a result,
economic activity in Ohio, as in many other industrially developed



                                       34
<PAGE>


states, tends to be more cyclical than in some other states and in the nation
as a whole. Agriculture also is an important segment of the economy in the
State. With 15 million acres (of a total land area of 26.4 million acres) in
farm land and an estimated 80,000 individual farms, it is by many measures
Ohio's leading industry, contributing $6.3 billion to the State's economy each
year. Agriculture represents 16% of total employment (approximately 1,055,000
jobs in 1996) and 11% of the value-added products produced in the State. Gross
farm income alone amounted in 1996 to just under $6.3 billion. In 1997, Ohio
exported over approximately $1.4 billion in farm products (primarily soybeans
and related soy products, and feed grains). The State has instituted several
programs to provide financial assistance to farmers.

     Ohio continues as a major "headquarters" state. Of the top 500 individual
corporations (industrial, commercial and service) based on 1998 revenues as
reported in 1999 by Fortune magazine, 27 had headquarters in Ohio, placing Ohio
fifth as a "headquarters" state.


     Payroll employment in Ohio, in the diversifying employment base, showed a
steady upward trend until 1979, then decreased until 1982. It reached a high in
the summer of 1993 after a slight decrease in 1992, then decreased slightly and
reached a new high in 1998. Growth in recent years has been concentrated among
non-manufacturing industries, with manufacturing employment tapering off since
its 1969 peak. Non-manufacturing industries now employ approximately 80% of all
non-agricultural payroll workers in Ohio.


     Consistent with the Ohio constitutional provision that no appropriation
may be made for a period longer than two years, the State operates on the basis
of a fiscal biennium for its appropriations and expenditures. Under current law
that biennium for operating purposes runs from July 1 in an odd-numbered year
to June 30 in the next odd-numbered year; for example, the current fiscal
biennium began July 1, 1999 and ends June 30, 2001.


     The Ohio Constitution imposes a duty on the General Assembly to "provide
for raising revenue, sufficient to defray the expenses of the state, for each
year, and also a sufficient sum to pay the principal and interest as they
become due on the state debt." The State is effectively precluded by law from
ending a Fiscal Year or a biennium in a "deficit" position. State borrowing to
meet casual deficits or failures in revenues or to meet expenses not otherwise
provided for is limited by the Ohio Constitution to $750,000.


     Most State operations are financed through the general revenue fund (GRF),
with personal income and sales-use taxes being the major GRF sources, totaling
$7.1 billion and $5.8 billion in 1999, respectively. In 1981, a Budget
Stabilization Fund (BSF), sometimes referred to as a "rainy day" fund, was
created for purposes of cash and budgetary management. In 1992, the entire
balance of the BSF was transferred to the GRF. At the end of the 1997-99
biennium, the BSF had a balance of approximately $953.2 million.


     The Ohio Revised Code provides that if the Governor ascertains that the
available revenue receipts and balances for the GRF or other funds for the then
current Fiscal Year will in all probability be less than the appropriations for
the year, he shall issue such orders to State agencies as will prevent their
expenditures and incurred obligations from exceeding those revenue receipts and
balances. The Governor implemented this directive in some prior years,
including Fiscal Years 1992 and 1993. There is no present constitutional limit
on the rates of State-levied taxes and excises, except for taxes on intangible
property. At present the State itself does not levy any ad valorem taxes on
real or tangible personal property. Those taxes are levied by local political
subdivisions. The Ohio Constitution limits the amount of ad valorem property
taxes that may be levied by local political subdivisions in the aggregate,
without a vote of the electors or a municipal charter provision, to 1% of the
true value, and statutes further limit the amount of the aggregate levy,
without a vote or charter provision, to 10 mills per $1 of assessed valuation.

     The GRF ending (June 30) fund balance is typically reduced during less
favorable national economic periods and then increases during more favorable
economic periods. For example, following the 1974-75 nationwide recession the
1977 GRF ending fund balance was $21.6 million. The balance (without assistance
from any significant tax rate increases) was $245.7 million in 1979, and then,


                                       35
<PAGE>


paralleling the national economic situation, was at the significantly lower
amount of $200 million in 1981. Recent biennium GRF ending fund balances were
$135.3 million in 1991, $111 million in 1993, $928 million in 1995, and $834.9
million in 1997. For the Biennium ended June 30, 1999, the GRF fund balance was
$976.7 million. Of that amount, $46.3 million was transferred to the Budget
Stabilization Fund (BSF), $325.7 million was transferred for school building
assistance, approximately $90 million was transferred for school computer
programs, and approximately $293 million was transferred to the State income
tax reduction fund.

     The GRF appropriations bill for the 1998-99 biennium was passed on June
25, 1997, and promptly signed, with selective vetoes, by the Governor. The act
provides for total GRF biennial expenditures of approximately $39.8 billion, an
increase over those for the 1997-99 fiscal biennium ($36 billion).


     Necessary GRF debt service and lease-rental appropriations for the entire
biennium were requested in the Governor's budget proposal and incorporated in
the related appropriations bill as introduced, and in the bill's versions as
passed by the House and the Senate and in the act as passed and signed. The
same is true for the separate Department of Transportation, Department of
Public Safety, and Bureau of Workers' Compensation appropriations acts,
containing lease-rental appropriations for certain DOT, DPS and BWC projects
financed by the Ohio Building Authority.


     Although revenue obligations of the State or its political subdivisions
may be payable from a specific project or source, including lease rentals,
there can be no assurance that, as in any state, future economic difficulties
and the resulting impact on State and local government finances will not
adversely affect the market value of the Bonds in the portfolio of the Ohio
Series or the ability of the respective obligors to make timely payments of
principal and interest on such Bonds.

     Litigation, similar to that in other states, has been pending since 1991
questioning the constitutionality of Ohio's system of school funding. The Ohio
Supreme Court concluded in a 1997 decision that major aspects of the system
(including basic operating assistance and certain loan programs) are
unconstitutional. It ordered the State to provide for and fund sufficiently a
system complying with the Ohio Constitution, staying its order to permit time
for responsive corrective actions by the General Assembly. The Court has
indicated that property taxes may still play a role in, but "can no longer be
the primary means" of, school funding. The Court also confirmed that
contractual repayment provisions of certain debt obligations issued for school
funding will remain valid after the stay terminates. The Court remanded the
case to the trial court to hear evidence and to render an opinion on the
constitutionality of the enacted legislation, which opinion could then be
appealed directly to the Ohio Supreme Court.

     The trial court subsequently conducted a hearing considering the
constitutionality of the legislation enacted since 1991 to enhance school
funding in Ohio and, in February, 1999, issued its ruling that the State
continues not to be in compliance with the constitutional requirements outlined
by the Ohio Supreme Court. The trial court judge ordered the State "forthwith
to provide for and fund a system of funding public elementary and secondary
education in compliance with the Ohio Constitution and the [1997] directive of
the Ohio Supreme Court" and directed the State Board of Education and
Superintendent of Public Education to submit proposals for compliance to the
General Assembly.

     The State appealed the trial court's decision to the Ohio Supreme Court,
which granted a stay pending the appeal and which held oral arguments in
November, 1999. At this time, it remains uncertain what the decision on appeal
might be and, should the plaintiffs prevail on appeal, the effect on the
State's school funding system.

     As part of its response, the General Assembly has increased State funding
for public schools. In addition, the General Assembly placed two issues on the
May 1998 primary ballot. Neither was approved by the voters. One was a
constitutional amendment authorizing additional State debt issuing capacity and
the other an increase in the State sales tax. The sales tax proposal would have
increased the State sales and use tax from 5% to 6%, estimated to generate over
$1 billion; one-half of increased revenues would have been applied to pay costs
of school operations and facilities, and the other half to additional homestead
property tax relief. At the November, 1999 election, voters approved a
constitutional amendment authorizing the issuance of general obligation debt
for school buildings and higher education facilities.



                                       36

     Litigation is also pending in federal district court challenging the
former Medicaid eligibility rules that were applied between 1990 and 1995 by
the Ohio Department of Human Services in the case of married couples where one
spouse lived in a nursing home and the other spouse resided in the community.
If the plaintiffs in that action are ultimately successful, it is estimated
that the State could be required to incur additional obligations of as much as
$240 million. At this time, the outcome of such litigation is uncertain.


     The summary information furnished above is based on official statements
prepared by the State of Ohio in connection with its borrowings and contains
such information as the Fund deems relevant in considering an investment in the
Fund. It does not purport to be a complete description of the considerations
contained therein.

     THE PENNSYLVANIA SERIES -- SPECIAL INVESTMENT CONSIDERATIONS. Presented
below is information concerning the Commonwealth of Pennsylvania and certain
issuers within the Commonwealth. Such information is based principally on
information drawn from recent official statements relating to securities
offerings by the Commonwealth and does not purport to be a complete description
of such issuers or factors that could adversely affect them. The Investment
Manager has not independently verified such information; however, it has no
reason to believe that such information is not correct in all material
respects. This information does not cover all municipal issuers within the
Commonwealth whose securities may be purchased by the Fund.

     Investment Securities. The Pennsylvania Series will invest principally in
Commonwealth and Commonwealth-related obligations and obligations of local
government units in the Commonwealth and obligations of related authorities.
The market value and marketability of the obligations of the Commonwealth and,
though generally to a lesser extent, the Commonwealth-related obligations and
the local governmental unit and related authority obligations generally will be
affected by economic conditions affecting the Commonwealth and litigation
matters which may adversely affect the Commonwealth. The market value and
marketability of obligations of issuers other than the Commonwealth may also be
affected by more localized economic changes, changes affecting the particular
revenue stream supporting such obligations and related litigation matters.

     The City of Philadelphia has experienced financial difficulties in the
past, as a result of which Moody's and S&P lowered their ratings of City of
Philadelphia general obligations below investment grade. Both Moody's and S&P
have since raised their ratings of City of Philadelphia general obligations to
Baa2 and BBB, respectively. Consequently, such obligations are currently
investment grade.


     General Socio-Economic and Economic Information Regarding the
Commonwealth. The Commonwealth is the fifth most populous state (ranking behind
California, New York, Texas and Florida) with a population of approximately 12
million for the last ten years. The Commonwealth is the headquarters for many
major corporations. It has been historically identified as a heavy industry
state although that reputation has changed over the last 30 years as the
industrial composition of the Commonwealth diversified when the coal, steel and
railroad industries began to decline. The major new sources of growth in the
Commonwealth are in the service sector, including trade, medical and health
services, education and financial institutions. Manufacturing employment has
fallen from 18.8% of non-agricultural employment in 1992 to 17.2% in 1998,
while service sector employment has increased from 29.4% of non-agricultural
employment in 1991 to 32.3% in 1998. From 1983 to 1990, the Commonwealth's
annual average unemployment rate dropped from 11.8% to 5.4% (below the national
average for each of the years from 1986). In 1998 and 1999, the average annual
unemployment rates for the Commonwealth were 4.6% and 4.3%, respectively,
compared to rates of 4.5% and 4.1% for the United States for such years.


     The Commonwealth utilizes the fund method of accounting. For purposes of
governmental accounting, a "fund" is defined as an independent fiscal and
accounting entity with a self-balancing set of accounts, for the purpose of
carrying on specific activities or attaining certain objectives in accordance
with the fund's special regulations, restrictions or limitations. In the
Commonwealth, funds are established by legislative enactment or in certain
cases by administrative action.

     The General Fund, the Commonwealth's largest fund, receives all tax
revenues, non-tax revenues and federal grants and entitlements that are not
specified by law to be deposited elsewhere. The majority


                                       37
<PAGE>

of the Commonwealth's operating and administrative expenses are payable from
the General Fund. Debt service on all Commonwealth obligations, except those
issued for highway purposes or for the benefit of other special revenue funds,
is payable from the General Fund.


     Revenues in the General Fund include all tax receipts, license and fee
payments, fines, penalties, interest and other revenues of the Commonwealth not
specified to be deposited elsewhere or not restricted to a specific program or
expenditure and federal revenues. Taxes levied by the Commonwealth are the most
significant source of revenues in the General Fund. The major tax sources for
the General Fund are the sales tax, which accounted for $6.61 billion or 35.1%
of General Fund tax revenues in fiscal 1999, the personal income tax, which
accounted for $6.68 billion or 35.5% of 1999 General Fund tax revenues, and the
corporate taxes which accounted for $2.83 billion or 15.0% of tax revenues.
Federal revenues are those federal receipts which pay or reimburse the
Commonwealth for funds disbursed for federally assisted programs.

     The primary expenditures of the General Fund are for education (over $7.50
billion in fiscal 1999) and public health and welfare (over $6.0 billion).

     The Constitution and laws of the Commonwealth require all payments from
the General Fund, with the exception of refunds of taxes, licenses, fees and
other charges, to be made only by duly enacted appropriations. Amounts
appropriated from the General Fund may not exceed its actual and estimated
revenues for the fiscal year plus any surplus available. Appropriations are
generally made for one fiscal year and are returned to the unappropriated
surplus of the fund (a lapse) if not spent or encumbered by the end of the
fiscal year. The Commonwealth's fiscal year begins July 1 and ends June 30.
(Fiscal 1999 refers to the fiscal year ending June 30, 1999.)

     For the five year period fiscal 1995 through fiscal 1999, total revenues
and other sources rose at a 6.0% average annual rate while total expenditures
and other uses grew by 5.0% annually.

     Program areas having the largest increase in costs for the fiscal 1994 to
fiscal 1999 period were for economic development and assistance protection of
persons and property, due to an expansion of state prisons. Recent efforts to
control costs of public health and welfare programs have resulted in
expenditure increases of 5.9% for the five year period.


     The Constitution requires tax and fee revenues relating to motor fuels and
vehicles to be used for highway purposes, and the tax revenues relating to
aviation fuels to be used for aviation purposes. Accordingly, all such
revenues, except the revenues from one-half cent per gallon of the liquid fuels
tax which are deposited in the Liquid Fuels Tax Fund for distribution to local
municipalities, are placed in the Motor License Fund, as are most federal aid
revenues designated for transportation programs. Operating and administrative
costs for the Department of Transportation and other Commonwealth departments
conducting transportation related programs, including the highway patrol
activities of the Pennsylvania State Police, are also paid from the Motor
License Fund. Debt service on bonds issued by the Commonwealth for highway
purposes is payable from the Motor License Fund.

     Other special revenue funds have been established by law to receive
specified revenues that are appropriated to specific departments, boards and/or
commissions for payment of their operating and administrative costs. Such funds
include the Game, Fish, Boating, Banking Department, Milk Marketing, State Farm
Products Show, State Racing and State Lottery Funds. Some of these special
revenue funds are required to transfer excess revenues to the General Fund and
some receive funding, in addition to their specified revenues, through
appropriations from the General Fund.

     In 1986, the General Assembly created the Tax Stabilization Reserve Fund
and provided for its initial funding from General Fund appropriations. Income
for this fund comes from annual appropriations of money from other Commonwealth
funds and investment earnings. The Tax Stabilization Reserve Fund is to be used
for emergencies threatening the health, safety or welfare of citizens or to
offset unanticipated revenue shortfalls due to economic downturns. Assets of
this fund may be used upon recommendation by the Governor and an approving vote
by two-thirds of the members of each house of the General Assembly.


                                       38

     The State Lottery Fund is a special revenue fund for the receipt of
lottery ticket sales and lottery licenses and fees. Its revenues, after payment
of prizes, are dedicated to paying the operational and administrative costs of
the lottery and the costs of programs benefiting the elderly in Pennsylvania.

     The Commonwealth maintains trust and agency funds which are used to
administer funds received pursuant to a specific bequest or as an agent for
other governmental units or individuals.

     Enterprise funds are maintained for departments or programs operated like
private enterprises. The largest of these funds is the State Stores Fund which
is used for the receipts and disbursements of the Commonwealth's liquor store
system. Sale and distribution of all liquor within Pennsylvania is a government
enterprise.

     The following information, which is based principally on information drawn
from recent Official Statements relating to securities offerings by the
Commonwealth, provides information regarding certain Pennsylvania issuers of
investment securities.

     State and Certain State-related Obligations. The Constitutional provisions
pertaining to Commonwealth debt permit the issuance of the following types of
debt: (i) debt to suppress insurrection or rehabilitate areas affected by
disaster, (ii) electorate approved debt, (iii) debt for capital projects,
subject to an aggregate debt limit of 1.75 times the annual average tax
revenues of the preceding five fiscal years, and (iv) tax anticipation note
debt payable in the fiscal year of issuance. All debt except tax anticipation
note debt must be amortized in substantial and regular amounts.

     The Commonwealth may incur debt to fund capital projects for community
colleges, highways, public improvements, transportation assistance, flood
control, redevelopment assistance, site development and the Pennsylvania
Industrial Development Authority. Before a project may be funded, it must be
itemized in a capital budget bill adopted by the General Assembly. An annual
capital budget bill states the maximum amount of debt for capital projects that
may be incurred during the current fiscal year for projects authorized in the
current or previous years' capital budget bills. Capital projects debt is
subject to a Constitutional limit on debt. Once capital projects debt has been
authorized by the necessary legislation, issuance authority rests with two of
the Issuing Officials (the Governor, the Auditor General and the State
Treasurer), one of whom must be the Governor.

     The issuance of electorate approved debt is subject to the enactment of
legislation which places on the ballot the question of whether debt shall be
incurred. Such legislation must state the purposes for which the debt is to be
authorized and, as a matter of practice, includes a maximum amount of funds to
be borrowed. Upon electorate approval and enactment of legislation implementing
the proposed debt-funded program, bonds may be issued. All such authorizing
legislation to date has given issuance authority to two of the Issuing
Officials, one of whom must be the Governor.


     Outstanding general obligation debt totaled $4,925 million at June 30,
1999, a decrease of $197 million from June 30, 1998. Over the 10-year period
ending June 30, 1999, total outstanding general obligation debt increased at an
annual rate of 0.5%. Within the most recent 5-year period, outstanding general
obligation debt has decreased at an annual rate of 0.6%.


     Certain state-created agencies have statutory authorization to incur debt
for which state appropriations to pay debt service thereon is not required. The
debt of these agencies is supported by assets of, or revenues derived from, the
various projects financed and is not an obligation of the Commonwealth. Some of
these agencies, however, are indirectly dependent on Commonwealth
appropriations. These agencies, their purposes and their outstanding debt are
as follows:


     Delaware River Joint Toll Bridge Commission ("DRJTBC"): The DRJTBC, a
public corporation of the Commonwealth and New Jersey, owns and operates
bridges across the Delaware River. Debt service on bonds is paid from tolls and
other revenues of the Commission. The DRJTBC had $51.4 million in bonds
outstanding as of June 30, 1999.

     Delaware River Port Authority ("DRPA"): The DRPA, a public corporation of
the Commonwealth and New Jersey, operates several toll bridges over the
Delaware River and promotes the use of the Philadelphia-Camden port. Debt
service on bonds is paid from toll revenues and other revenues pledged by DRPA
to repayment of bonds. The DRPA had $623.2 million in revenue bond debt
outstanding on June 30, 1999.



                                       39
<PAGE>


     Pennsylvania Economic Development Financing Authority ("PEDFA"): The PEDFA
was created in 1987 to offer pooled bond issues for both taxable and tax-exempt
bonds on behalf of local industrial and commercial development authorities for
economic development projects. Bonds may be secured by loan repayments and all
other revenues of the PEDFA. The PEDFA had $1,239.7 million of debt outstanding
as of June 30, 1999.

     Pennsylvania Energy Development Authority ("PEDA"): The PEDA was created
in 1982 to finance energy research projects, demonstration projects promoting
the production or conservation of energy and the promotion, utilization and
transportation of Pennsylvania energy resources. The authority's funding is
from appropriations and project revenues. Debt service on bonds is paid from
project revenues and other revenues pledged by PEDA to repayment of bonds. The
PEDA had $42.1 million in bonds outstanding as of June 30, 1999.

     Pennsylvania Higher Education Assistance Agency ("PHEAA"): The PHEAA makes
or guarantees student loans to students or parents, or to lending institutions
or postsecondary institutions. Debt service on the bonds is paid by loan
interest and repayments and other agency revenues. The PHEAA had $1,783.8
million in bonds outstanding as of June 30, 1999.

     Pennsylvania Higher Education Facilities Authority ("PHEFA"): The PHEFA is
a public corporation of the Commonwealth established to finance college
facilities. As of June 30, 1999, the PHEFA had $3,522.5 million in revenue
bonds and notes outstanding payable from the lease rentals or loan repayments
of the projects financed. Some of the lessees or borrowers, although private
institutions, receive grants and subsidies from the Commonwealth.

     Pennsylvania Industrial Development Authority ("PIDA"): The PIDA is a
public corporation of the Commonwealth established for the purpose of financing
economic development. The PIDA had $373.8 million in revenue bond debt
outstanding on June 30, 1999, to which all of its revenues are pledged.

     Pennsylvania Turnpike Commission ("PTC"): The PTC operates the
Pennsylvania Turnpike System. Its outstanding indebtedness, $1,573.1 million as
of June 30, 1999, is payable from the net revenues of the System, primarily
toll revenues and rentals from leases and concessions.

     Pennsylvania Infrastructure Investment Authority ("PIIA"): The PIIA was
created in 1988 to provide low interest rate loans and grants for the purpose
of constructing new and improving existing water supply and sewage disposal
systems to protect the health and safety of the citizens of the Commonwealth
and to promote economic development within the Commonwealth. Loans and grants
are available to local governments and, in certain circumstances, to private
companies. The PIIA bonds are secured by principal repayments and interest
payments on PIIA loans. The PIIA had $186.9 million in revenue bonds
outstanding as of June 30, 1999.

     Philadelphia Regional Port Authority ("PRPA"): The PRPA was created in
1989 for the purpose of acquiring and operating port facilities in Bucks and
Delaware Counties, and the City of Philadelphia. Debt service on the bonds is
paid by a pledge of the PRPA's revenues, rentals and receipts. The PRPA had
$57.9 million in bonds outstanding as of June 30, 1999.

     State Public School Building Authority ("SPSBA"): The SPSBA finances
public school projects. Bonds issued by the SPSBA are supported by the lease
rental payments or loan repayments made to the SPSBA by local school districts
and the sponsors of community colleges. A portion of the funds appropriated
annually by the Commonwealth as aid to local school districts may be used by
them to pay such lease rental payments or loan repayments. The SPSBA had $347.5
million of revenue bonds outstanding on June 30, 1999.


     "Moral Obligations." Pennsylvania Housing Finance Agency ("PHFA"): The
PHFA is a state-created agency which provides financing for housing for lower
and moderate income families in the Commonwealth. The bonds, but not the notes,
of the PHFA are partially secured by a capital reserve fund required to be
maintained by the PHFA in an amount equal to the maximum annual debt service on
its outstanding bonds in any succeeding calendar year. The statute creating
PHFA provides that if there is


                                       40
<PAGE>


a potential deficiency in the capital reserve fund or if funds are necessary to
avoid default on interest, principal or sinking fund payments on bonds or notes
of PHFA, the Governor, upon notification from the PHFA, shall place in the
budget of the Commonwealth for the next succeeding year an amount sufficient to
make up any such deficiency or to avoid any such default. The budget as finally
adopted by the General Assembly may or may not include the amount so placed
therein by the Governor. PHFA is not permitted to borrow additional funds so
long as any deficiency exists in the capital reserve fund. As of June 30, 1999,
PHFA had $2,749.3 million of revenue bonds outstanding.


     The Hospitals and Higher Education Facilities Authority of Philadelphia
(the "Hospitals Authority"). The Hospitals Authority is a municipal authority
organized by the City of Philadelphia to, inter alia, acquire and prepare
various sites for use as intermediate care facilities for the mentally
retarded. On August 26, 1986, the Hospitals Authority issued $20.4 million of
bonds which were refunded in 1993 by a $21.1 million bond issue of the
Hospitals Authority (the "Hospitals Authority Bonds") for such facilities for
the City. The Hospitals Authority Bonds are secured by leases with the City
payable only from project revenues and a debt service reserve fund. The
Commonwealth's Department of Public Welfare ("DPW") has agreed with the
Hospitals Authority to request in DPW's annual budget submission to the
Governor, an amount of funds sufficient to alleviate any deficiency that may
arise in the debt service reserve fund for the Hospitals Authority Bonds. The
budget as finally adopted may or may not include the amount requested. If funds
are paid to the Hospitals Authority, DPW will obtain certain rights in the
property financed with the Hospitals Authority Bonds in return for such
payment.


     In response to a delay in the availability of billable beds and the
revenues from these beds to pay debt service on the Hospitals Authority Bonds,
PHFA agreed in June 1989 to provide a $2.2 million low-interest loan to the
Hospitals Authority. The loan enabled the Hospitals Authority to make all debt
service payments on the Hospitals Authority Bonds during 1990. Enough beds were
completed in 1991 to provide sufficient revenues to the Hospitals Authority to
meet its debt service payments and to begin repaying the loan from PHFA.
According to the Hospitals Authority, as of June 30, 1999, $1.0 million of the
loan principal was outstanding. DPW has agreed that the additional costs
arising from the PHFA loan will be reimbursed as necessary and reasonable costs
of the project.


     Local Governmental Unit and Related Authority Obligations. Various state
statutes authorize local units of government (counties, cities, school
districts and the like) to issue general obligations and revenue obligations,
subject to compliance with the requirements of such statutes. In addition,
various statutes permit local government units to organize authorities having
the power to issue obligations which are not subject to debt limits that may be
applicable to the organizing governmental unit and which are payable from
assets of or revenues derived from projects financed by such authorities. Such
authorities include parking authorities, industrial development authorities,
redevelopment authorities, transportation authorities, water and sewer
authorities, and authorities to undertake projects for institutions of higher
education and health care. Such obligations may generally be affected by
adverse changes in the economy of the area in which such local government units
or projects financed by them or by authorities created by them are located, by
changes in applicable federal, state or local law or regulation, or by changes
in levels of federal, state or local appropriations, grants or subsidies to the
extent such appropriations, grants or subsidies directly or indirectly affect
revenues of such issuers.


     Year 2000. A well-established programming standard in the computer
industry of using only two digits to identify a calendar year may prevent many
current computer systems from properly recognizing dates beyond the year 1999.
No material problems occurred in Commonwealth computer systems when the year
2000 arrived. However, there remains the potential for computers to malfunction
by producing erroneous data or failing completely through the early part of the
calendar year. The Governor made fixing the Year 2000 problem a top priority
for Pennsylvania state agencies under his jurisdiction. At the Governor's
direction, Pennsylvania undertook an aggressive program to make its computer
systems Year 2000-compatible and to identify potential problems with entities
outside state government with which the Commonwealth does business or exchanges
data.

     For state agencies under the Governor's jurisdiction, all computer
programs that support essential state government services have been corrected,
tested and implemented. Remediation efforts by the



                                       41
<PAGE>


Treasury Department under its action plan were begun in the first quarter of
1997 and are complete. Testing of remediated code is complete. The projected
cost of the Commonwealth's Year 2000 modification work is not believed to be
material and is being paid from amounts appropriated out of current revenues.

     While state agencies and the Treasury Department have made every
reasonable effort to completely address potential Year 2000 impacts, there can
be no assurance that all of the Commonwealth's mission-critical and non
mission-critical computer programs or other technology will be entirely free
from Year 2000 related problems. Further, even if the Commonwealth successfully
addresses its own Year 2000-related problems, there can be no assurance that
any other entity or governmental agency providing services, information or
funds to the Commonwealth will be able to carry out their responsibilities to
the Commonwealth without disruption. A failure by the Commonwealth, other
governmental agencies, or other entities to remediate Year 2000-related
problems, including the timely receipt of tax and other revenues or the prompt
disbursement of funds, may cause a material adverse impact on Commonwealth
operations or finances. All of the potential risks and costs associated with
such a failure by the Commonwealth, other governmental agencies or other
entities cannot be accurately identified and quantified at this time. In
addition, it is not possible to quantify potential claims against the
Commonwealth resulting from Year 2000 noncompliance.



C. FUND POLICIES/INVESTMENT RESTRICTIONS

     The investment policies/restrictions listed below have been adopted by
each Series as fundamental policies. Under the Investment Company Act of 1940
(the "Investment Company Act"), a fundamental policy may not be changed without
the vote of a majority of the outstanding voting securities of the Series. The
Investment Company Act defines a majority as the lesser of (a) 67% or more of
the shares present at a meeting of shareholders, if the holders of 50% of the
outstanding shares of the Series are present or represented by proxy; or (b)
more than 50% of the outstanding shares of the Series. For purposes of the
following restrictions: (i) all percentage limitations apply immediately after
a purchase or initial investment; and (ii) any subsequent change in any
applicable percentage resulting from market fluctuations or other changes in
total or net assets does not require elimination of any security from the
portfolio.

     In addition, for purposes of the following restrictions: (a) an "issuer"
of a security is the entity whose assets and revenues are committed to the
payment of interest and principal on that particular security, provided that
the guarantee of a security will be considered a separate security and provided
further that a guarantee of a security shall not be deemed a security issued by
the guarantor if the value of all securities guaranteed by the guarantor and
owned by a Series does not exceed 10% of the value of the total assets of the
Series; (b) a "taxable security" is any security the interest on which is
subject to federal income tax; and (c) all percentage limitations apply
immediately after a purchase or initial investment, and any subsequent change
in any applicable percentage resulting from market fluctuations or other
changes in total or net assets does not require elimination of any security
from the portfolio.

     Each Series may not:

     1.   Invest in common stock.

     2.   Write, purchase or sell puts, calls, or combinations thereof, except
          for options on futures contracts or options on debt securities.

     3.   Invest 25% or more of the value of its total assets in securities of
          issuers in any one industry. This restriction does not apply to
          obligations issued or guaranteed by the United States Government, its
          agencies or instrumentalities or to municipal obligations, including
          those issued by the designated State of the Series or its political
          subdivisions.

     4.   Invest in securities of any issuer if, to the knowledge of the Series,
          any officer or trustee of the Fund or of the Investment Manager owns
          more than 1/2 of 1% of the outstanding securities of the issuer, and
          the officers and trustees who own more than 1/2 of 1% own in the
          aggregate more than 5% of the outstanding securities of the issuer.


                                       42
<PAGE>

     5.   Purchase or sell real estate or interests therein (including limited
          partnership interests), although it may purchase securities secured
          by real estate or interests therein.

     6.   Purchase or sell commodities except that the Series may purchase
          financial futures contracts and related options.

     7.   Borrow money, except that each Series may borrow from a bank for
          temporary or emergency purposes in amounts not exceeding 5% (taken at
          the lower of cost or current value) of the value of the total assets
          of the Series (including the amount borrowed) less its liabilities
          (not including any borrowings but including the fair market value at
          the time of computation of any senior securities then outstanding).

     8.   Pledge its assets or assign or otherwise encumber them except to
          secure permitted borrowing. However, for the purpose of this
          restriction, collateral arrangements with respect to the writing of
          options and collateral arrangements with respect to initial margin
          for futures are not deemed to be pledges of assets and neither such
          arrangements nor the purchase or sale of futures are deemed to be the
          issuance of a senior security as set forth in restriction 10.

     9.   Issue senior securities as defined in the Act, except insofar as the
          Series may be deemed to have issued a senior security by reason of:
          (a) entering into any repurchase agreement; (b) purchasing any
          securities on a when-issued or delayed delivery basis; or (c)
          borrowing money in accordance with the restrictions described above.

     10.  Make loans of money or securities, except: (a) by the purchase of
          debt obligations in which each Series may invest consistent with its
          investment objective and policies; (b) by investment in repurchase
          agreements; and (c) by lending its portfolio securities.

     11.  Make short sales of securities.

     12.  Purchase securities on margin, except for such short-term loans as
          are necessary for the clearance of purchases of portfolio securities.
          The deposit or payment by the Series of initial or variation margin
          in connection with futures contracts or related options thereon is
          not considered the purchase of a security on margin.

     13.  Engage in the underwriting of securities, except insofar as the
          Series may be deemed an underwriter under the Securities Act in
          disposing of a portfolio security.

     14.  Invest for the purpose of exercising control or management of any
          other issuer.

     15.  Purchase oil, gas or other mineral leases, rights or royalty
          contracts, or exploration or development programs.

     16.  Purchase securities of other investment companies, except in
          connection with a merger, consolidation, reorganization or
          acquisition of assets.


     Notwithstanding any other investment policy or restriction, each Series
may seek to achieve its investment objective by investing all or substantially
all of its assets in another investment company having substantially the same
investment objective and policies as the Series.


III. MANAGEMENT OF THE FUND
- --------------------------------------------------------------------------------

A. BOARD OF TRUSTEES


     The Board of Trustees of the Fund oversees the management of each Series
but does not itself manage a Series. The Trustees review various services
provided by or under the direction of the Investment Manager to ensure that
each Series' general investment policies and programs are properly carried out.
The Trustees also conduct their review to ensure that administrative services
are provided to each Series in a satisfactory manner.

     Under state law, the duties of the Trustees are generally characterized as
a duty of loyalty and a duty of care. The duty of loyalty requires a Trustee to
exercise his or her powers in the interest of the Fund and each Series and not
the Trustee's own interest or the interest of another person or organization. A



                                       43
<PAGE>

Trustee satisfies his or her duty of care by acting in good faith with the care
of an ordinarily prudent person and in a manner the Trustee reasonably believes
to be in the best interest of the Fund, each Series and its shareholders.


B. MANAGEMENT INFORMATION


     TRUSTEES AND OFFICERS. The Board of the Fund consists of eight (8)
Trustees. These same individuals also serve as directors or trustees for all of
the Morgan Stanley Dean Witter Funds. Six Trustees (75% of the total number)
have no affiliation or business connection with the Investment Manager or any
of its affiliated persons and do not own any stock or other securities issued
by the Investment Manager's parent company, MSDW. These are the
"non-interested" or "independent" Trustees. The other two Trustees (the
"management Trustees") are affiliated with the Investment Manager.

     The Trustees and executive officers of the Fund, their principal business
occupations during the last five years and their affiliations, if any, with the
Investment Manager, and with the Morgan Stanley Dean Witter Funds (there were
93 such Funds as of the calendar year ended December 31, 1999), are shown
below.

Manager and MSDW Services Company, are Assistant Secretaries of the Fund.

     INDEPENDENT DIRECTORS/TRUSTEES AND THE COMMITTEES. Law and regulation
establish both general guidelines and specific duties for the independent
directors/trustees. The Morgan Stanley Dean Witter Funds seek as independent
directors/trustees individuals of distinction and experience in business and
finance, government service or academia; these are people whose advice and
counsel are in demand by others and for whom there is often competition. To
accept a position on the Funds' boards, such individuals may reject other
attractive assignments because the Funds make substantial demands on their time.
All of the independent directors/trustees serve as members of the Audit
Committee. In addition, three of the directors/trustees, including two
independent directors/trustees, serve as members of the Derivative's Committee
and the Insurance Committee.

     The independent directors/trustees are charged with recommending to the
full board approval of management, advisory and administration contracts, Rule
12b-1 plans and distribution and underwriting agreements; continually reviewing
Fund performance; checking on the pricing of portfolio securities, brokerage
commissions, transfer agent costs and performance, and trading among Funds in
the same complex; and approving fidelity bond and related insurance coverage
and allocations, as well as other matters that arise from time to time. The
independent directors/trustees are required to select and nominate individuals
to fill any independent directors/trustees vacancy on the board of any Fund
that has a Rule 12b-1 plan of distribution. Most of the Morgan Stanley Dean
Witter Funds have a Rule 12b-1 plan.

     The Audit Committee is charged with recommending to the full board the
engagement or discharge of the Fund's independent accountants; directing
investigations into matters within the scope of the independent accountants'
duties, including the power to retain outside specialists; reviewing with the
independent accountants the audit plan and results of the auditing engagement;
approving professional services provided by the independent accountants and
other accounting firms prior to the performance of the services; reviewing the
independence of the independent accountants; considering the range of audit and
non-audit fees; reviewing the adequacy of the Fund's system of internal
controls; and preparing and submitting Committee meeting minutes to the full
board.

     The board of each Fund has a Derivatives Committee to approve parameters
for and monitor the activities of the Fund with respect to derivative
investments, if any, made by the Fund.

     Finally, the board of each Fund has formed an Insurance Committee to
review and monitor the insurance coverage maintained by the Fund.

     ADVANTAGES OF HAVING SAME INDIVIDUALS AS INDEPENDENT DIRECTORS/TRUSTEES FOR
ALL MORGAN STANLEY DEAN WITTER FUNDS. The independent directors/trustees and the
Funds' management believe that having the same independent directors/trustees
for each of the Morgan Stanley Dean Witter Funds avoids the duplication of
effort that would arise from having different groups of individuals serving as
independent directors/trustees for each of the Funds or even of sub-groups of
Funds. They believe that having the same individuals serve as independent
directors/trustees of all the Funds tends to increase their knowledge and
expertise regarding matters which affect the Fund complex generally and enhances
their ability to negotiate on behalf of each Fund with the Fund's service
providers. This arrangement also precludes the possibility of separate groups of
independent directors/trustees arriving at conflicting decisions regarding
operations and management of the Funds and avoids the cost and confusion that



                                       47
<PAGE>


would likely ensue. Finally, having the same independent directors/trustees
serve on all Fund boards enhances the ability of each Fund to obtain, at modest
cost to each separate Fund, the services of independent directors/trustees of
the caliber, experience and business acumen of the individuals who serve as
independent directors/trustees of the Morgan Stanley Dean Witter Funds.


     TRUSTEE AND OFFICER INDEMNIFICATION. The Fund's Declaration of Trust
provides that no Trustee, officer, employee or agent of the Fund is liable to
the Fund or to a shareholder, nor is any Trustee, officer, employee or agent
liable to any third persons in connection with the affairs of the Fund, except
as such liability may arise from his/her or its own bad faith, willful
misfeasance, gross negligence or reckless disregard of his/her or its duties.
It also provides that all third persons shall look solely to the Fund property
for satisfaction of claims arising in connection with the affairs of the Fund.
With the exceptions stated, the Declaration of Trust provides that a Trustee,
officer, employee or agent is entitled to be indemnified against all liability
in connection with the affairs of the Fund.

C. COMPENSATION


     The Fund pays each Independent Trustee an annual fee of $800 plus a per
meeting fee of $50 for meetings of the Board of Trustees, the Independent
Trustees or Committees of the Board of Trustees attended by the Trustee (the
Fund pays the Chairman of the Audit Committee an additional annual fee of $750
and the Chairmen of the Derivatives and Insurance Committees additional annual
fees of $500). If a Board meeting and a meeting of the Independent Trustees or
a Committee meeting, or a meeting of the Independent Trustees and/or more than
one Committee meeting, take place on a single day, the Trustees are paid a
single meeting fee by the Fund. The Fund also reimburses such Trustees for
travel and other out-of-pocket expenses incurred by them in connection with
attending such meetings. Trustees and officers of the Fund who are or have been
employed by the Investment Manager or an affiliated company receive no
compensation or expense reimbursement from the Fund for their services as
Trustee.

     The following table illustrates the compensation that the Fund paid to its
Independent Trustees for the fiscal year ended November 30, 1999.

     As of the date of this Statement of Additional Information, 55 of the
Morgan Stanley Dean Witter Funds, including the Fund, have adopted a retirement
program under which an independent director/  trustee who retires after serving
for at least five years (or such lesser period as may be determined by the
Board) as an independent director/trustee of any Morgan Stanley Dean Witter
Fund that has adopted the retirement program (each such Fund referred to as an
"Adopting Fund" and each such trustee referred to as an "Eligible Trustee") is
entitled to retirement payments upon reaching the eligible retirement age
(normally, after attaining age 72). Annual payments are based upon length of
service.

     Currently, upon retirement, each Eligible Trustee is entitled to receive
from the Adopting Fund, commencing as of his or her retirement date and
continuing for the remainder of his or her life, an annual retirement benefit
(the "Regular Benefit") equal to 30.22% of his or her Eligible Compensation
plus 0.5036667% of such Eligible Compensation for each full month of service as
an independent director /trustee of any Adopting Fund in excess of five years
up to a maximum of 60.44% after ten years of service. The foregoing percentages
may be changed by the Board.(1) "Eligible Compensation" is one-fifth of the
total compensation earned by such Eligible Trustee for service to the Adopting
Fund in the five year period prior to the date of the Eligible Trustee's
retirement. Benefits under the retirement program are accrued as expenses on
the books of the Adopting Funds. Such benefits are not secured or funded by the
Adopting Funds.

     The following table illustrates the retirement benefits accrued to the
Fund's Independent Trustees by the Fund for the fiscal year ended November 30,
1999 and by the 55 Morgan Stanley Dean Witter Funds (including the Fund) for
the year ended December 31, 1999, and the estimated retirement benefits for the
Independent Trustees, to commence upon their retirement, from the Fund as of
November 30, 1999 and from the 55 Morgan Stanley Dean Witter Funds as of
December 31, 1999.


- ----------
(1)   An Eligible Trustee may elect alternative payments of his or her
      retirement benefits based upon the combined life expectancy of the
      Eligible Trustee and his or her spouse on the date of such Eligible
      Trustee's retirement. In addition, the Eligible Trustee may elect that
      the Surviving spouse's periodic payment of benefits will be equal to a
      lower percentage of the periodic amount when both spouses were alive. The
      amount estimated to be payable under this method, through the remainder
      of the later of the lives of the Eligible Trustee and spouse, will be the
      actuarial equivalent of the Regular Benefit.

V. INVESTMENT MANAGEMENT AND OTHER SERVICES
- --------------------------------------------------------------------------------

A. INVESTMENT MANAGER



     The Investment Manager to each Series is Morgan Stanley Dean Witter
Advisors Inc., a Delaware corporation, whose address is Two World Trade Center,
New York, NY 10048. The Investment Manager is a wholly-owned subsidiary of
MSDW, a Delaware corporation. MSDW is a preeminent global financial services
firm that maintains leading market positions in each of its three primary
businesses: securities, asset management and credit services.


     Pursuant to an Investment Management Agreement (the "Management
Agreement") with the Investment Manager, the Fund has retained the Investment
Manager to provide administrative services and manage the investment of each
Series' assets, including the placing of orders for the purchase and sale of
portfolio securities for the Series. Each Series pays the Investment Manager
monthly compensation calculated daily by applying the annual rate of 0.35% to
the net assets of that Series determined as of the close of each business day.


     During the fiscal year ended November 30, 1997, the Arizona Series,
California Series, Florida Series, Massachusetts Series, Michigan Series,

     The Investment Manager has retained its wholly-owned subsidiary, MSDW
Services Company, to perform administrative services for the Fund.


B. PRINCIPAL UNDERWRITER

     The Fund's principal underwriter is the Distributor (which has the same
address as the Investment Manager). In this capacity, each Series' shares are
distributed by the Distributor. The Distributor has entered into a selected
dealer agreement with Dean Witter Reynolds, which through its own sales
organization sells shares of each Series. In addition, the Distributor may
enter into similar agreements with other selected broker-dealers. The
Distributor, a Delaware corporation, is a wholly-owned subsidiary of MSDW.

     The Distributor bears all expenses it may incur in providing services
under the Distribution Agreement. These expenses include the payment of
commissions for sales of Series shares and incentive compensation to Financial
Advisors, the cost of educational and/or business-related trips, and
educational and/or promotional and business-related expenses. The Distributor
also pays certain expenses in connection with the distribution of the shares of
each Series, including the costs of preparing, printing and distributing
advertising or promotional materials, and the costs of printing and
distributing prospectuses and supplements thereto used in connection with the
offering and sale of Series shares. The Fund bears the costs of initial
typesetting, printing and distribution of prospectuses and supplements thereto
to shareholders. The Fund also bears the costs of registering the Fund and the
Series' shares under federal and state securities laws and pays filing fees in
accordance with state securities laws.


     The Fund and the Distributor have agreed to indemnify each other against
certain liabilities, including liabilities under the Securities Act. Under the
Distribution Agreement, the Distributor uses its best efforts in rendering
services to the Fund, but in the absence of willful misfeasance, bad faith,
gross negligence or reckless disregard of its obligations, the Distributor is
not liable to the Fund or any of its shareholders for any error of judgment or
mistake of law or for any act or omission or for any losses sustained by the
Fund or its shareholders.


C. SERVICES PROVIDED BY THE INVESTMENT MANAGER


     The Investment Manager manages the investment of each Series' assets,
including the placing of orders for the purchase and sale of portfolio
securities. The Investment Manager obtains and evaluates the information and
advice relating to the economy, securities markets, and specific securities as
it considers necessary or useful to continuously manage the assets of a Series
in a manner consistent with its investment objective.

     Under the terms of the Management Agreement, in addition to managing each
Series' investments, the Investment Manager maintains certain of each Series'
books and records and furnishes, at its own expense, the office space,
facilities, equipment, clerical help, bookkeeping and certain legal services as
each Series may reasonably require in the conduct of its business, including
the preparation of prospectuses, proxy statements and reports required to be
filed with federal and state securities commissions (except insofar as the
participation or assistance of independent accountants and attorneys is, in the
opinion of the Investment Manager, necessary or desirable). In addition, the
Investment Manager pays the salaries of all personnel, including officers of
the Fund, who are employees of the Investment Manager. The Investment Manager
also bears the cost of telephone service, heat, light, power and other
utilities provided to the Fund.

     Each Series pays all expenses incurred in its operation and a portion of
the Fund's general administration expenses allocated on the basis of asset size
of the respective Series. Expenses not


                                       51
<PAGE>

expressly assumed by the Investment Manager under the Management Agreement or
by the Distributor, will be paid by the Fund or each respective Series
depending upon the nature of the expense. The expenses borne directly by each
Series include, but are not limited to: expenses of the Plan of Distribution
pursuant to Rule 12b-1; charges and expenses of any registrar, custodian, stock
transfer and dividend disbursing agent; brokerage commissions; taxes; engraving
and printing share certificates; registration costs of the Series and its
shares under federal and state securities laws; the cost and expense of
printing, including typesetting, and distributing prospectuses and statements
of additional information of the Series and supplements thereto to the Series'
shareholders; all expenses of shareholders' and Trustees' meetings and of
preparing, printing and mailing of proxy statements and reports to
shareholders; fees and travel expenses of Trustees or members of any advisory
board or committee who are not employees of the Investment Manager or any
corporate affiliate of the Investment Manager; all expenses incident to any
dividend, withdrawal or redemption options; charges and expenses of any outside
service used for pricing of the Fund's shares; fees and expenses of legal
counsel, including counsel to the Trustees who are not interested persons of
the Fund or of the Investment Manager (not including compensation or expenses
of attorneys who are employees of the Investment Manager); fees and expenses of
the Fund's independent accountants; membership dues of industry associations;
interest on Series borrowings; postage; insurance premiums on property or
personnel (including officers and Trustees) of the Fund which inure to its
benefit; extraordinary expenses including, but not limited to, legal claims and
liabilities and litigation costs and any indemnification relating thereto
(depending upon the nature of the legal claim, liability or lawsuit, the costs
of litigation, payment of legal claims or liabilities or indemnification
relating thereto may be directly applicable to a particular Series or may be
proportionately allocated on the basis of the size of each Series. The Trustees
have determined that this is an appropriate method of allocation of such
expenses); and all other costs of the Fund's operation.

     The Management Agreement provides that in the absence of willful
misfeasance, bad faith, gross negligence or reckless disregard of its
obligations thereunder, the Investment Manager is not liable to the Fund or any
of its investors for any act or omission by the Investment Manager or for any
losses sustained by the Fund or its investors.


     The Management Agreement will remain in effect from year to year with
respect to each Series, provided continuance of the Management Agreement is
approved at least annually by the vote of the holders of a majority, as defined
in the Investment Company Act, of the outstanding shares of that Series, or by
the Trustees; provided that in either event such continuance is approved
annually by the vote of a majority of the Trustees, including a majority of the
Independent Trustees.


D. DEALER REALLOWANCES

     Upon notice to selected broker-dealers, the Distributor may reallow up to
the full applicable front-end sales charge during periods specified in such
notice. During periods when 90% or more of the sales charge is reallowed, such
selected broker-dealers may be deemed to be underwriters as that term is
defined in the Securities Act.

E. RULE 12b-1 PLAN

     In accordance with a Plan of Distribution pursuant to Rule 12b-1 under the
Investment Company Act between the Fund and the Distributor, the Distributor
provides certain services in connection with the promotion of sales of Fund
shares (the "Plan").

     The Plan provides that the Distributor bears the expense of all
promotional and distribution related activities on behalf of the Fund, except
for expenses that the Trustees determine to reimburse, as described below. The
following activities and services may be provided by the Distributor under the
Plan: (1) compensation to and expenses of Dean Witter Reynolds' Financial
Advisors and other Selected Broker-Dealers' account executives and other
employees, including overhead and telephone expenses; (2) sales incentives and
bonuses to sales representatives and to marketing personnel in connection with
promoting sales of the Fund's shares; (3) expenses incurred in connection with
promoting sales of the


                                       52
<PAGE>

Fund's shares; (4) preparing and distributing sales literature; and (5)
providing advertising and promotional activities, including direct mail
solicitation and television, radio, newspaper, magazine and other media
advertisements.

     The Fund is authorized to reimburse specific expenses incurred or to be
incurred in promoting the distribution of Series shares. Reimbursement is made
through payments at the end of each month. The amount of each monthly payment
may in no event exceed an amount equal to a payment at the annual rate of 0.15
of 1% of the average daily net assets of the shares of each Series of the Fund
during the month. No interest or other financing charges will be incurred for
which reimbursement payments under the Plan will be made. In addition, no
interest charges, if any, incurred on any distribution expenses will be
reimbursable under the Plan. In the case of all expenses other than expenses
representing a residual to Financial Advisors and other authorized financial
representatives, such amounts shall be determined at the beginning of each
calendar quarter by the Trustees, including a majority of the Independent 12b-1
Trustees. Expenses representing a residual to Financial Advisors and other
authorized financial representatives may be reimbursed without prior
determination. In the event that the Distributor proposes that monies shall be
reimbursed for other than such expenses, then in making quarterly
determinations of the amounts that may be expended by the Fund, the Distributor
provides and the Trustees review a quarterly budget of projected incremental
distribution expenses to be incurred on behalf of the Fund, together with a
report explaining the purposes and anticipated benefits of incurring such
expenses. The Trustees determine which particular expenses, and the portions
thereof, that may be borne by the Fund, and in making such a determination
shall consider the scope of the Distributor's commitment to promoting the
distribution of Series shares.


     The Arizona Series, California Series, Florida Series, Massachusetts
Series, Michigan Series, Minnesota Series, New Jersey Series, New York Series,
Ohio Series and Pennsylvania Series, accrued a total of $56,078, $150,122,
$82,273, $20,384, $24,004, $11,455, $57,692, $16,977, $24,023 and $78,314,
respectively pursuant to the Plan of Distribution for the fiscal year ended
November 30, 1999. Such payment amounted to an annual rate of 0.14 of 1% of the
average daily net assets of the Arizona Series, Florida Series, Massachusetts
Series, Michigan Series, Minnesota Series, New Jersey Series and Ohio Series
and, 0.15% of the daily net assets of the California Series, New York Series
and Pennsylvania Series. It is estimated that the amount paid by the Fund for
distribution was for expenses which relate to compensation of sales personnel
and associated overhead expenses. The Distributor has informed the Fund that it
received sales charges on sales of the Fund's shares in the approximate amounts
of $912,113, $994,943, and $840,754 for the fiscal years ended 1997, 1998, and
1999, respectively.

     The Investment Manager pays a retention fee to Financial Advisors at an
annual rate of 0.05% of the value of shares of the Fund sold after January 1,
2000 and held for at least one year. Shares purchased through the reinvestment
of dividends will be eligible for a retention fee, provided that such dividends
were earned on shares otherwise eligible for a retention fee payment. Shares
owned in variable annuities, closed-end fund shares and shares held in 401(k)
plans where the Transfer Agent or Dean Witter Reynolds's Retirement Plan
Services is either recordkeeper or trustee are not eligible for a retention
fee.

     For the first year only, the retention fee is paid on any shares of the
Fund sold after January 1, 2000 and held by shareholders on December 31, 2000.

     The retention fees are paid by the Investment Manager from its own assets,
which may include profits from investment management fees payable under the
Management Agreement, as well as from borrowed funds.


     Under the Plan, the Distributor uses its best efforts in rendering
services to the Fund, but in the absence of willful misfeasance, bad faith,
gross negligence or reckless disregard of its obligations, the Distributor is
not liable to the Fund or any of its shareholders for any error of judgment or
mistake of law or for any act or omission or for any losses sustained by the
Fund or its shareholders.

     Under the Plan, the Distributor provides each of the Series the Fund, for
review by the Trustees, and the Trustees review, promptly after the end of each
fiscal quarter, a written report regarding the


                                       53
<PAGE>

incremental distribution expenses incurred on behalf of each of each Series the
Fund during such fiscal quarter, which report includes (1) an itemization of
the types of expenses and the purposes therefore; (2) the amounts of such
expenses; and (3) a description of the benefits derived by each Series of the
Fund. In the Trustees' quarterly review of the Plan they consider its continued
appropriateness and the level of compensation provided therein.


     No interested person of the Fund nor any Independent Trustee has any
direct financial interest in the operation of the Plan except to the extent
that the Distributor, the Investment Manager, Dean Witter Reynolds, MSDW
Services Company or certain of their employees may be deemed to have such an
interest as a result of benefits derived from the successful operation of the
Plan or as a result of receiving a portion of the amounts expended thereunder
by the Fund.



F. OTHER SERVICE PROVIDERS

VI. BROKERAGE ALLOCATION AND OTHER PRACTICES
- --------------------------------------------------------------------------------

A. BROKERAGE TRANSACTIONS

     Subject to the general supervision of the Trustees, the Investment Manager
is responsible for decisions to buy and sell securities for each Series, the
selection of brokers and dealers to effect the transactions, and the
negotiation of brokerage commissions, if any. Each Series expects that the
primary market for the securities in which it intends to invest will generally
be the over-the-counter market. Securities are generally traded in the
over-the-counter market on a "net" basis with dealers acting as principal for
their own accounts without a stated commission, although the price of the
security usually includes a profit to the dealer. Each Series also expects that
securities will be purchased at times in underwritten offerings where the price
includes a fixed amount of compensation, generally referred to as the
underwriter's concession or discount. On occasion each Series may also purchase
certain money market instruments directly from an issuer, in which case no
commissions or discounts are paid.


     During the fiscal years ended November 30, 1997, 1998 and 1999, the Fund
and each Series paid no such brokerage commissions or concessions.


                                       54
<PAGE>

B. COMMISSIONS

     Pursuant to an order of the SEC, each Series may effect principal
transactions in certain money market instruments with Dean Witter Reynolds.
Each Series will limit its transactions with Dean Witter Reynolds to U.S.
Government and Government Agency Securities, Bank Money Instruments (i.e.
Certificates of Deposit and Bankers' Acceptances) and Commercial Paper (not
including Tax-Exempt Municipal Paper). The transactions will be effected with
Dean Witter Reynolds only when the price available from Dean Witter Reynolds is
better than that available from other dealers.


     During the fiscal years ended November 30, 1997, 1998 and 1999, the Series
did not effect any principal transactions with Dean Witter Reynolds.

     Brokerage transactions in securities listed on exchanges or admitted to
unlisted trading privileges may be effected through Dean Witter Reynolds,
Morgan Stanley & Co. and other affiliated brokers and dealers. In order for an
affiliated broker or dealer to effect any portfolio transactions on an exchange
for any Series, the commissions, fees or other remuneration received by the
affiliated broker or dealer must be reasonable and fair compared to the
commissions, fees or other remuneration paid to other brokers in connection
with comparable transactions involving similar securities being purchased or
sold on an exchange during a comparable period of time. This standard would
allow the affiliated broker or dealer to receive no more than the remuneration
which would be expected to be received by an unaffiliated broker in a
commensurate arm's-length transaction. Furthermore, the Trustees, including the
Independent Trustees, have adopted procedures which are reasonably designed to
provide that any commissions, fees or other remuneration paid to an affiliated
broker or dealer are consistent with the foregoing standard. Each Series does
not reduce the management fee it pays to the Investment Manager by any amount
of the brokerage commissions it may pay to an affiliated broker or dealer.

     During the fiscal years ended November 30, 1997, 1998 and 1999, the Fund
and the Series paid no brokerage commissions to an affiliated broker or dealer.




C. BROKERAGE SELECTION

     The policy of the Fund regarding purchases and sales of securities for
each Series' portfolio is that primary consideration will be given to obtaining
the most favorable prices and efficient executions of transactions.

     In seeking to implement the Fund's policies, the Investment Manager
effects transactions with those brokers and dealers who the Investment Manager
believes provide the most favorable prices and are capable of providing
efficient executions. If the Investment Manager believes the prices and
executions are obtainable from more than one broker or dealer, it may give
consideration to placing portfolio transactions with those brokers and dealers
who also furnish research and other services to the Fund or the Investment
Manager. The services may include, but are not limited to, any one or more of
the following: information as to the availability of securities for purchase or
sale; statistical or factual information or opinions pertaining to investment;
wire services; and appraisals or evaluations of portfolio securities.

     The information and services received by the Investment Manager from
brokers and dealers may be of benefit to the Investment Manager in the
management of accounts of some of its other clients and may not in all cases
benefit the Fund directly. While the receipt of such information and services
is useful in varying degrees and would generally reduce the amount of research
or services otherwise performed by the Investment Manager and thereby reduce
its expenses, it is of indeterminable value and the Fund does not reduce the
management fee it pays to the Investment Manager by any amount that may be
attributable to the value of such services.

     Subject to the principle of obtaining best price and execution, the
Investment Manager may consider a broker-dealer's sales of shares of a Series
as a factor in selecting from among those broker-dealers qualified to provide
comparable prices and execution on the Series' portfolio transactions. The Fund
does not, however, require a broker-dealer to sell shares of a Series in order
for it to be considered to execute portfolio transactions, and will not enter
into any arrangement whereby a specific amount or


                                       55
<PAGE>

percentage of a Series' transactions will be directed to a broker which sells
shares of the Series to customers. The Trustees review, periodically, the
allocation of brokerage orders to monitor the operation of these policies.

     The Investment Manager currently serves as investment manager to a number
of clients, including other investment companies, and may in the future act as
investment manager or advisor to others. It is the practice of the Investment
Manager to cause purchase and sale transactions to be allocated among the
Series and others whose assets it manages in such manner as it deems equitable.
In making such allocations among the Series and other client accounts, various
factors may be considered, including the respective investment objectives, the
relative size of portfolio holdings of the same or comparable securities, the
availability of cash for investment, the size of investment commitments
generally held and the opinions of the persons responsible for managing the
portfolios of the Series and other client accounts. In the case of certain
initial and secondary public offerings, the Investment Manager utilizes a pro
rata allocation process based on the size of the Morgan Stanley Dean Witter
Funds involved and the number of shares available from the public offering.


D. DIRECTED BROKERAGE


     During the fiscal year ended November 30, 1999, the Fund did not pay any
brokerage commissions to brokers because of research services provided.



E. REGULAR BROKER-DEALERS


     During the fiscal year ended November 30, 1999, the Fund did not purchase
securities issued by brokers or dealers that were among the ten brokers or the
ten dealers which executed transactions for or with the Fund in the largest
dollar amounts during the year. At November 30, 1999, the Fund did not own any
securities issued by any of such issuers.


VII. CAPITAL STOCK AND OTHER SECURITIES
- --------------------------------------------------------------------------------

     The shareholders of each Series of the Fund are entitled to a full vote
for each full share of beneficial interest held. The Fund is authorized to
issue an unlimited number of shares of beneficial interest. All shares of
beneficial interest of the Fund are of $0.01 par value and are equal as to
earnings, assets and voting privileges.

     The Fund's Declaration of Trust permits the Trustees to authorize the
creation of additional series of shares (the proceeds of which would be
invested in separate, independently managed portfolios) and additional Classes
of shares within any series. The Trustees have not presently authorized any
such additional series or Classes of shares other than as set forth in the
Prospectus.


     The Fund is not required to hold annual meetings of shareholders and in
ordinary circumstances the Fund does not intend to hold such meetings. The
Trustees may call special meetings of shareholders for action by shareholder
vote as may be required by the Investment Company Act or the Declaration of
Trust. Under certain circumstances, the Trustees may be removed by action of the
Trustees. In addition, under certain circumstances, the shareholders may call a
meeting to remove Trustees and the Fund is required to provide assistance in
communicating with shareholders about such a meeting. The voting rights of
shareholders are not cumulative, so that holders of more than 50 percent of the
shares voting can, if they choose, elect all Trustees being selected, while the
holders of the remaining shares would be unable to elect any Trustees.


     Under Massachusetts law, shareholders of a business trust may, under
certain limited circumstances, be held personally liable as partners for the
obligations of the Fund. However, the Declaration of Trust contains an express
disclaimer of shareholder liability for acts or obligations of the Fund,
requires that notice of such Fund obligations include such disclaimer, and
provides for indemnification out of the Fund's property for any shareholder
held personally liable for the obligations of the Fund. Thus, the risk of a
shareholder incurring financial loss on account of shareholder liability is
limited to circumstances in which the Fund itself would be unable to meet its
obligations. Given the above limitations on shareholder


                                       56
<PAGE>

personal liability, and the nature of the Fund's assets and operations, the
possibility of the Fund being unable to meet its obligations is remote and
thus, in the opinion of Massachusetts counsel to the Fund, the risk to Fund
shareholders of personal liability is remote.

     All of the Trustees have been elected by the shareholders of the Fund,
most recently at a Special Meeting of Shareholders held on May 21, 1997. The
Trustees themselves have the power to alter the number and the terms of office
of the Trustees (as provided for in the Declaration of Trust), and they may at
any time lengthen or shorten their own terms or make their terms of unlimited
duration and appoint their own successors, provided that always at least a
majority of the Trustees has been elected by the shareholders of the Fund.

VIII. PURCHASE, REDEMPTION AND PRICING OF SHARES
- --------------------------------------------------------------------------------

A. PURCHASE/REDEMPTION OF SHARES


     Information concerning how the shares of each Series are offered to the
public (and how they are redeemed and exchanged) is provided in the Fund's
Prospectus.

     TRANSFER AGENT AS AGENT. With respect to the redemption or repurchase of
Series shares, the application of proceeds to the purchase of new shares in a
Series or any other Morgan Stanley Dean Witter Funds and the general
administration of the exchange privilege, the Transfer Agent acts as agent for
the Distributor and for the shareholder's authorized broker-dealer, if any, in
the performance of such functions. With respect to exchanges, redemptions or
repurchases, the Transfer Agent shall be liable for its own negligence and not
for the default or negligence of its correspondents or for losses in transit.
The Fund shall not be liable for any default or negligence of the Transfer
Agent, the Distributor or any authorized broker-dealer.

     The Distributor and any authorized broker-dealer have appointed the
Transfer Agent to act as their agent in connection with the application of
proceeds of any redemption of Fund shares to the purchase of shares of any
other Morgan Stanley Dean Witter Fund and the general administration of the
exchange privilege. No commission or discounts will be paid to the Distributor
or any authorized broker-dealer for any transaction pursuant to the exchange
privilege.


B. OFFERING PRICE

     The price of each Series, called "net asset value," is based on the value
of each Series' portfolio securities.

     Portfolio securities (other than short-term debt securities and futures
and options) are valued for the Fund by an outside independent pricing service
approved by the Trustees. The pricing service has informed the Fund that in
valuing the portfolio securities for each Series it uses both a computerized
grid matrix of tax-exempt securities and evaluations by its staff, in each case
based on information concerning market transactions and quotations from dealers
which reflect the bid side of the market each day. The portfolio securities for
each Series are thus valued by reference to a combination of transactions and
quotations for the same or other securities believed to be comparable in
quality, coupon, maturity, type of issue, call provisions, trading
characteristics and other features deemed to be relevant. The Trustees believe
that timely and reliable market quotations are generally not readily available
to the Fund for purposes of valuing tax-exempt securities and that the
valuations supplied by the pricing service, using the procedures outlined above
and subject to periodic review, are more likely to approximate the fair value
of such securities. The Investment Manager will periodically review and
evaluate the procedures, methods and quality of services provided by the
pricing service then being used by the Fund and may, from time to time,
recommend to the Trustees the use of other pricing services or discontinuance
of the use of any pricing service in whole or part. The Trustees may determine
to approve such recommendation or take other provisions for pricing of the
portfolio securities for each Series.

     Short-term taxable debt securities with remaining maturities of 60 days or
less at time of purchase are valued at amortized cost, unless the Trustees
determine such does not reflect the securities' market value, in which case
these securities will be valued at their fair value as determined by the
Trustees.


                                       57
<PAGE>

Other taxable short-term debt securities with maturities of more than 60 days
will be valued on a mark to market basis until such time as they reach a
maturity of 60 days, whereupon they will be valued at amortized cost using
their value on the 61st day unless the Trustees determine such does not reflect
the securities' fair value, in which case these securities will be valued at
their fair market value as determined by the Trustees. Listed options on debt
securities are valued at the latest sale price on the exchange on which they
are listed unless no sales of such options have taken place that day, in which
case, they will be valued at the mean between their closing bid and asked
prices. Unlisted options on debt securities are valued at the mean between
their latest bid and asked price. Futures are valued at the latest sale price
on the commodities exchange on which they trade unless the Trustees determines
that such price does not reflect their fair value, in which case they will be
valued at their fair market value as determined by the Trustees. All other
securities and other assets are valued at their fair value as determined in
good faith under procedures established by and under the supervision of the
Trustees.

IX. TAXATION OF THE FUND AND SHAREHOLDERS
- --------------------------------------------------------------------------------

     Each Series generally will make three basic types of distributions: tax
exempt dividends, ordinary dividends and long-term capital gain distributions.
These types of distributions are reported differently on a shareholder's income
tax return and they are also subject to different rates of tax. The tax
treatment of the investment activities of each Series will affect the amount
and timing and character of the distributions made by the Series. Shareholders
are urged to consult their own tax professionals regarding specific questions
as to federal, state or local taxes.

     INVESTMENT COMPANY TAXATION. Each Series intends to remain qualified as a
regulated investment company under Subchapter M of the Internal Revenue Code of
1986. As such, each Series will not be subject to federal income tax on its net
investment income and capital gains, if any, to the extent that it distributes
such income and capital gains to its shareholders.

     Each Series generally intends to distribute sufficient income and gains so
that the Series will not pay corporate income tax on its earnings. Each Series
also generally intends to distribute to its shareholders in each calendar year
a sufficient amount of ordinary income and capital gains to avoid the
imposition of a 4% excise tax. However, a Series may instead determine to
retain all or part of any ordinary income or capital gains in any year for
reinvestment. In such event, such Series will pay federal income tax (and
possibly excise tax) on such retained gains.

     Gains or losses on sales of securities by a Series will be long-term
capital gains or losses if the securities have a tax holding period of more
than one year. Gains or losses on the sale of securities with a tax holding
period of one year or less will be short-term gains or losses.

     In computing net investment income, each Series will amortize any premiums
and original issue discounts on securities owned, if applicable. Capital gains
or losses realized upon sale or maturity of such securities will be based on
their amortized cost.

     All or a portion of any gain from tax-exempt obligations purchased at a
market discount may be treated as ordinary income rather than capital gain.

     From time to time, proposals have been introduced before Congress for the
purpose of restricting or eliminating the federal income tax exemption for
interest on municipal securities. Similar proposals may be introduced in the
future. If such a proposal were enacted, the availability of municipal
securities for investment by a Series could be affected. In that event, each
Series would re-evaluate its investment objective and policies.


     TAXATION OF DIVIDENDS AND DISTRIBUTIONS. Each Series intends to qualify to
pay "exempt-interest dividends" to its shareholders by maintaining, as of the
close of each quarter of each of its taxable years, at least 50% of the value of
its assets in tax-exempt securities. An exempt-interest dividend is that part of
the dividend distributions made by a Series which consists of interest received
by the Series on tax-exempt securities upon which the shareholder incurs no
federal income taxes. Exempt-interest dividends are included, however, in
determining what portion, if any, of a person's Social Security benefits are
subject to federal income tax.



                                       58
<PAGE>

     Each Series intends to invest a portion of its assets in certain "private
activity bonds". As a result, a portion of the exempt-interest dividends paid
by each Series will be an item of tax preference to shareholders subject to the
alternative minimum tax. Certain corporations which are subject to the
alternative minimum tax may also have to include exempt-interest dividends in
calculating their alternative minimum taxable income in situations where the
"adjusted current earnings" of the corporation exceeds its alternative minimum
taxable income.


     Shareholders will be subject to federal income tax on dividends paid from
interest income derived from taxable securities and on distributions of net
short-term capital gains. Such dividends and distributions are taxable to the
shareholder as ordinary dividend income regardless of whether the shareholder
receives such distributions in additional shares or in cash. Distributions of
long-term capital gains, if any, are taxable as long-term capital gains,
regardless of how long the shareholder has held the Series shares and
regardless of whether the distribution is received in additional shares or in
cash. The maximum tax rate on long-term capital gains applicable to individuals
is 20%. Since the income of each Series is expected to be derived entirely from
interest rather than dividends, it is anticipated that no portion of such
dividend distributions will be eligible for the federal dividends received
deduction available to corporations.


     Shareholders are generally taxed on any ordinary dividend or capital gain
distributions from a Series in the year they are actually distributed. However,
if any such dividends or distributions are declared in October, November or
December and paid in January then such amounts will be treated for tax purposes
as received by the shareholders on December 31, to shareholders of record of
such month.

     Shareholders who are not citizens or residents of the United States and
certain foreign entities may be subject to withholding of United States tax on
distributions made by a Series of any taxable interest income and short term
capital gains.


     After the end of each calendar year, shareholders will be sent information
on their dividends and capital gain distributions for tax purposes, including
the portion taxable as ordinary income, the portion taxable as long-term capital
gains and the percentage of any distributions which constitute an item of tax
preference for purposes of the alternative minimum tax.


     PURCHASES AND REDEMPTIONS AND EXCHANGES OF SERIES SHARES. Any dividend or
capital gains distribution received by a shareholder from a Series will have
the effect of reducing the net asset value of the shareholder's stock in the
Series by the exact amount of the dividend or capital gains distribution.
Furthermore, capital gains distributions and some portion of the dividends may
be subject to federal income taxes. If the net asset value of the shares should
be reduced below a shareholder's cost as a result of the payment of dividends
or the distribution of realized long-term capital gains, such payment or
distribution would be in part a return of the shareholder's investment but
nonetheless would be taxable to the shareholder. Therefore, an investor should
consider the tax implications of purchasing shares of a Series immediately
prior to a distribution record date.


     In general, a sale of shares results in capital gain or loss, and for
individual shareholders, is taxable at a federal rate dependent upon the length
of time the shares were held. A redemption of a shareholder's Series shares is
normally treated as a sale for tax purposes. Shares of a Series held for a
period of one year or less will, for tax purposes, generally result in
short-term gains or losses and those held for more than one year generally
result in long-term gain or loss. Under current law, the maximum tax rate on
long-term capital gains is 20%. Any loss realized by shareholders upon a sale
or redemption of shares within six months of the date of their purchase will be
(i) treated as a long-term capital loss to the extent of any distributions of
net long-term capital gains and (ii) disallowed to the extent of exempt interest
dividends received with respect to such shares.


     Gain or loss on the sale or redemption of shares in the Series is measured
by the difference between the amount received and the tax basis of the shares.
Shareholders should keep records of investments made (including shares acquired
through reinvestment of dividends and distributions) so they can compute the
tax basis of their shares. Under certain circumstances a shareholder may
compute and use an average cost basis in determining the gain or loss on the
sale or redemption of shares.


                                       59
<PAGE>

     Exchanges of shares in a Series for shares of another Series or for shares
of other Morgan Stanley Dean Witter Funds, are also subject to similar tax
treatment. Such an exchange is treated for tax purposes as a sale of the
original shares in the first Series, followed by the purchase of shares in the
second Series or Fund.

     If a shareholder realizes a loss on the redemption or exchange of a shares
in a Series and reinvests in shares of such Series within 30 days before or
after the redemption or exchange, the transactions may be subject to the "wash
sale" rules, resulting in a postponement of the recognition of such loss for
tax purposes.

     Interest on indebtedness incurred by shareholders to purchase or carry
shares of the Series is not deductible. Furthermore, entities or persons who
are "substantial users" (or related persons) of facilities financed by
industrial development bonds should consult their tax advisers before
purchasing shares of a Series. "Substantial user" is defined generally by
Treasury Regulation Section 1.103-11(b) as including a "non-exempt person" who
regularly uses in a trade or business a part of a facility financed from the
proceeds of industrial development bonds.


     THE ARIZONA SERIES -- SPECIAL TAX CONSIDERATIONS. Under a ruling and
published guidance issued by the Arizona Department of Revenue in 1984 and
1991, respectively, distributions from the Arizona Series that are received by
shareholders that are Arizona taxpayers will not be subject to Arizona income
tax to the extent that those distributions are attributable to interest on
tax-exempt obligations of the State of Arizona or interest on obligations of
the United States. Distributions from the Arizona Series attributable to
obligations of the governments of Puerto Rico, the Virgin Islands and Guam also
are excludible from Arizona income tax pursuant to federal law. Other
distributions from the Arizona Series, including those related to short-term
and long-term capital gains, generally will be taxable under Arizona law when
received by Arizona taxpayers. Like federal law, Arizona law allows taxpayers a
deduction for interest on indebtedness incurred to purchase property held for
investment to the extent of such taxpayer's net investment income. However,
interest on indebtedness incurred (directly or indirectly) by a shareholder to
purchase or carry shares of the Arizona Series is not deductible for Arizona
income tax purposes to the extent that the Arizona Series holds tax-exempt
obligations of the State of Arizona, obligations of the United States, and
obligations of Puerto Rico, the Virgin Islands and Guam.


     The foregoing discussion assumes that in each taxable year the Arizona
Series qualifies and elects to be taxed as a regulated investment company for
federal income tax purposes. In addition, the following discussion assumes that
in each taxable year the Arizona Series qualifies to pay exempt-interest
dividends by complying with the requirement of the Code that at least 50% of
its assets at the close of each quarter of its taxable year is invested in
state, municipal or other obligations, the interest on which is excluded from
gross income for federal income tax purposes pursuant to section 103(a) of the
Code.

     THE CALIFORNIA SERIES -- SPECIAL TAX CONSIDERATIONS. In any year in which
the Fund qualifies as a regulated investment company under the Internal Revenue
Code as in effect on January 1, 1998, and is exempt from federal income tax,
(i) the California Series will also be exempt from the California corporate
income and franchise taxes to the extent it distributes its income and (ii),
provided 50% or more of the value of the total assets of the California Series
at the close of each quarter of its taxable year consists of obligations the
interest on which (when held by an individual) is exempt from personal income
taxation under California law, the California Series will be qualified under
California law to pay "exempt-interest" dividends which will be exempt from the
California personal income tax.

     The portion of dividends constituting exempt-interest dividends is that
portion derived from interest on obligations which pay interest excludable from
California personal income under California law. The total amount of California
exempt-interest dividends paid by the California Series to all of its
shareholders with respect to any taxable year cannot exceed the amount of
interest received by the California Series during such year on such obligations
less any expenses and expenditures (including dividends paid to corporate
shareholders) deemed to have been paid from such interest. Any dividends paid
to corporate shareholders subject to the California franchise tax will be taxed
as ordinary dividends to such shareholders.

                                       60
<PAGE>

     Individual shareholders of the California Series who reside in California
will not be subject to California personal income tax on distributions received
from the California Series to the extent such distributions are attributable to
interest received by the California Series during its taxable year on
obligations, the interest on which (when held by an individual) is exempt from
taxation under California law.

     Because, unlike federal law, California law does not impose personal
income tax on an individual's Social Security benefits, the receipt of
California exempt-interest dividends will have no effect on an individual's
California personal income tax.

     Individual shareholders will normally be subject to federal and California
personal income tax on dividends paid from interest income derived from taxable
securities and distributions of net capital gains. In addition, distributions
other than exempt-interest dividends to such shareholders are includable in
income subject to the California alternative minimum tax. For federal income
tax and California personal income tax purposes, distributions of long-term
capital gains, if any, are taxable to shareholders as long-term capital gains,
regardless of how long a shareholder has held shares of the California Series
and regardless of whether the distribution is received in additional shares or
in cash. The maximum federal capital gains rate for individuals is 20% with
respect to capital assets held more than 12 months. The maximum capital gains
rate for corporate shareholders is the same as the maximum tax rate for
ordinary income. In addition, unlike federal law, the shareholders of the
California Series will not be subject to tax, or receive a credit for tax paid
by the California Series, on undistributed capital gains, if any.

     Interest on indebtedness incurred by shareholders or related parties to
purchase or carry shares of an investment company paying exempt-interest
dividends, such as the California Series, generally will not be deductible by
the investor for federal or state personal income tax purposes. In addition, as
a result of California's incorporation of certain provisions of the Code, a
loss realized by a shareholder upon the sale of shares held for six months or
less may be disallowed to the extent of any exempt-interest dividends received
with respect to such shares. Moreover, any loss realized upon the redemption of
shares within six months from the date of purchase of such shares and following
receipt of a long-term capital gains distribution will be treated as long-term
capital loss to the extent of such long-term capital gains distribution.
Finally, any loss realized upon the redemption of shares within 30 days before
or after the acquisition of other shares of the Fund may be disallowed under
the "wash sale" rules.

     Distributions from investment income and long-term and short-term capital
gains will not be excludable from taxable income in determining the California
corporate franchise tax for corporate shareholders. Such distributions may also
be includable in income subject to the alternative minimum tax. In addition,
distributions from investment income and long-term and short-term capital gains
may be subject to state taxes in states other than California, and to local
taxes.

     THE FLORIDA SERIES -- SPECIAL TAX CONSIDERATIONS. Under existing Florida
law, neither the State of Florida nor any of its political subdivisions or
other governmental authorities may impose an income tax on individuals.
Accordingly, individual shareholders of the Florida Series will not be subject
to any Florida state or local income taxes on income derived from investments
in the Florida Series. However, such income may be subject to state or local
income taxation under applicable state or local laws in jurisdictions other
than Florida. In addition, the income received from the Florida Series may be
subject to estate taxes under present Florida law and certain corporations may
be subject to the taxes imposed by Chapter 220, Florida Statutes, on interest,
income or profits on debt obligations owned by corporations as defined in said
Chapter 220.

     The State of Florida also imposes an annual tax of 2 mills on each dollar
($2.00 per $1,000) of the just valuation of all intangible personal property
that has a taxable situs within the State with certain exemptions and
limitations. However, the entire value of a shareholder's interest in the
Florida Series will be exempt from Florida's intangible personal property tax
if, as is intended, all of the investments and other assets held by the Florida
Series on each annual assessment date are exempt individually from the
intangible personal property tax. It presently is the policy and intention of
the Fund and the Investment


                                       61
<PAGE>

Manager to manage the Florida Series in such a manner as to ensure that on each
annual assessment date the Florida Series will consist of only those
investments and other assets which are exempt from the Florida intangible
personal property tax. Accordingly, it is unlikely that any shareholder of the
Florida Series will ever be subject to such tax. In the event that the Florida
Series includes investments or other assets on the annual assessment date which
may subject shareholders to the Florida intangible personal property tax, the
Fund shall so notify the Shareholders.

     THE MASSACHUSETTS SERIES -- SPECIAL TAX CONSIDERATIONS. Under existing
Massachusetts law, provided the Massachusetts Series qualifies as a "regulated
investment company" under the Code, the Massachusetts Series will not be
subject to Massachusetts income or excise taxation. Shareholders of the
Massachusetts Series that are individuals, estates or trusts and are subject to
the Massachusetts personal income tax will not be subject to such tax on
distributions of the Massachusetts Series that qualify as "exempt-interest
dividends" under Section 852(b)(5) of the Code and are attributable to interest
received by the Massachusetts Series on obligations issued by The Commonwealth
of agencies and instrumentalities, or by Puerto Rico, the U.S. Virgin Islands
or Guam, which pay interest excludable from gross income under the Code and
exempt from Massachusetts personal income taxation. Other distributions to such
shareholders will generally be included in income subject to the Massachusetts
personal income tax, except for (1) distributions, if any, attributable to
interest received by the Massachusetts Series on direct obligations of the
United States and (2) distributions, if any, attributable to gain realized by
the Massachusetts Series on the sale of certain Massachusetts obligations
issued pursuant to Massachusetts statutes that specifically exempt such gain
from Massachusetts taxation. Dividends from the Massachusetts Series that
qualify as capital gain dividends under Section 852(b)(3)(C) of the Code, other
than such dividends described in the second clause of the preceding sentence,
will be treated as long-term capital gains for Massachusetts personal income
tax purposes.


     As a result of a change in the Massachusetts tax laws, applicable to
taxable years beginning on or after January 1, 1996, capital gain income from
the sale or exchange of shares of the Massachusetts Series will be taxed at a
stepped down rate depending on the number of years such shares have been held.
For purposes of determining the holding period, shares acquired prior to 1/1/96
shall be deemed to have been acquired on 1/1/95, or on the date of actual
acquisition, whichever is later. Further, long-term capital losses are
available to offset long-term and short-term gains. First, a loss in each
long-term period classification is available against gains in the same
classification; then they are available against other classifications beginning
with the gains at the highest rate level; then they are available against
short-term gains. Short-term capital losses may be applied against short-term
capital gains and the excess is able to offset long-term capital gains. In
addition, as a result of the changes in the Massachusetts tax laws, effective
January 1, 1999, any taxable interest and dividends (other than interest and
dividends from Massachusetts banks) is taxed at 5.95%, reduced from 12%.


     In determining the Massachusetts excise tax on corporations subject to
Massachusetts taxation, distributions from the Massachusetts Series, whether
attributable to taxable or tax-exempt income or gain realized by the
Massachusetts Series, will not be excluded from a corporate shareholder's net
income and, in the case of a shareholder that is an intangible property
corporation, shares of the Massachusetts Series will not be excluded from net
worth.

     THE MICHIGAN SERIES -- SPECIAL TAX CONSIDERATIONS. Under existing Michigan
law, to the extent that the distributions from the Michigan Series qualify as
"exempt-interest dividends" of a regulated investment company under Section
852(b)(5) of the Code which are attributable to interest on tax-exempt
obligations of the State of Michigan, its political or governmental
subdivisions, or its governmental agencies or instrumentalities ("Michigan
Obligations"), or obligations of the United States or its agencies or
possessions that are exempt from state taxation, such distributions will also
not be subject to Michigan income tax or Michigan single business tax.

     To the extent that distributions of the Michigan Series are derived from
other income, including long-or short-term capital gains, the distributions
will not be exempt from Michigan income tax or Michigan single business tax.


                                       62
<PAGE>

     Certain Michigan cities have adopted Michigan's uniform city income tax
ordinance, which under the Michigan city income tax act is the only income tax
ordinance that may be adopted by cities in Michigan. To the extent the
distributions on the Michigan Series are not subject to Michigan income tax,
they are not subject to any Michigan city's income tax.


     THE MINNESOTA SERIES -- SPECIAL TAX CONSIDERATIONS. Under existing
Minnesota law, provided the Minnesota Series qualifies as a "regulated
investment company" under the Code, and subject to the discussion in the
paragraph below, shareholders of the Minnesota Series who are individuals,
estates, or trusts, and who are subject to the regular Minnesota personal
income tax will not be subject to such regular Minnesota tax on Minnesota
Series dividends to the extent that such distributions qualify as
exempt-interest dividends of a regulated investment company under Section
852(b)(5) of the Code which are derived from interest income on tax-exempt
obligations of the State of Minnesota, or its political or governmental
subdivisions, municipalities, governmental agencies or instrumentalities
("Minnesota Sources"). The foregoing will apply, however, only if the portion
of the exempt-interest dividends from such Minnesota Sources that is paid to
all shareholders represents 95% or more of the exempt-interest dividends that
are paid by the Minnesota Series. If the 95% test is not met, all
exempt-interest dividends that are paid by the Minnesota Series generally will
be subject to the regular Minnesota personal income tax. Even if the 95% test
is met, to the extent that exempt-interest dividends that are paid by the
Minnesota Series are not derived from the Minnesota Sources described in the
first sentence of this paragraph, such dividends generally will be subject to
the regular Minnesota personal income tax. Other distributions of the Minnesota
Series, including distributions from net short-term and long-term capital
gains, are generally not exempt from the regular Minnesota personal income tax.

     Legislation enacted in 1995 provides that it is the intent of the
Minnesota legislature that interest income on obligations of Minnesota
governmental units, including obligations of the Minnesota Sources described
above, and exempt-interest dividends that are derived from interest income on
such obligations, be included for Minnesota income tax purposes in the net
income of individuals, estates and trusts, if it is judicially determined that
the exemption by Minnesota of such interest or such exempt-interest dividends
unlawfully discriminates against interstate commerce because interest income on
obligations of governmental issuers located in other states, or exempt-interest
dividends derived from such obligations, is so included. This provision
provides that it applies to taxable years that begin during or after the
calendar year in which such judicial decision becomes final, regardless of the
date on which the obligations were issued, and that other remedies apply for
previous taxable years. The United States Supreme Court in 1995 denied
certiorari in a case in which an Ohio state court upheld an exemption for
interest income on obligations of Ohio governmental issuers, even though
interest income on obligations of non-Ohio governmental issuers was subject to
tax. In 1997, the United States Supreme Court denied certiorari in a subsequent
case from Ohio, involving the same taxpayer and the same issue, in which the
Ohio Supreme Court refused to reconsider the merits of the case on the ground
that the previous final state court judgment barred any claim arising out of
the transaction that was the subject of the previous action. It cannot be
predicted whether a similar case will be brought in Minnesota or elsewhere, or
what the outcome of such case would be.

     Minnesota presently imposes an alternative minimum tax on individuals,
estates and trusts that is based, in part, on their federal alternative minimum
taxable income, which includes federal tax preference items. The Code provides
that interest on specified private activity bonds is a federal tax preference
item, and that an exempt-interest dividend of a regulated investment company
constitutes a federal tax preference item to the extent of its proportionate
share of the interest on such private activity bonds. Accordingly,
exempt-interest dividends that are attributable to such private activity bond
interest, even though they are derived from the Minnesota Sources described
above, will be included in the base upon which such Minnesota alternative
minimum tax is computed. In addition, the entire portion of exempt-interest
dividends that is derived from sources other than the Minnesota Sources
described above generally is also subject to the Minnesota alternative minimum
tax. Further, should the 95% test that is described above fail to be met, all
of the exempt-interest dividends that are paid by the Minnesota Series,
including all of those that are derived from the Minnesota Sources described
above, generally will be subject to the Minnesota alternative minimum tax.



                                       63
<PAGE>


     Subject to certain limitations that are set forth in the Minnesota rules,
Minnesota Series dividends, if any, that are derived from interest on certain
United States obligations are not subject to the regular Minnesota personal
income tax or the Minnesota alternative minimum tax, in the case of
shareholders of the Minnesota Series who are individuals, estates, or trusts.


     Minnesota Series distributions, including exempt-interest dividends, are
not excluded in determining the Minnesota franchise tax on corporations that is
measured by taxable income and alternative minimum taxable income.

     Minnesota Series distributions may also be taken into account in certain
cases in determining the minimum fee that is imposed on corporations, S
corporations and partnerships.


     Interest on indebtedness incurred or continued by a shareholder of the
Minnesota Series to purchase or carry shares of the Minnesota Series will
generally not be deductible for regular Minnesota personal income tax purposes
or Minnesota alternative minimum tax purposes, in the case of shareholders of
the Minnesota Series who are individuals, estates, or trusts.


     Shares of the Minnesota Series will not be subject to the Minnesota
personal property tax.

     THE NEW JERSEY SERIES -- SPECIAL TAX CONSIDERATIONS. Under existing New
Jersey law, as long as the New Jersey Series qualifies as a "qualified
investment fund," shareholders of the New Jersey Series may exclude certain
distributions from the New Jersey Series from gross income for purposes of
calculating the New Jersey gross income tax imposed on individuals, estates and
certain trusts. Distributions permitted to be excluded are those that are
attributable to interest or gain from obligations (1) issued by or on behalf of
New Jersey or any county, municipality, school or other district, agency,
authority, commission, instrumentality, public corporation, body corporate and
politic or political subdivision of New Jersey, or (2) statutorily free from
New Jersey or local taxation under other acts of New Jersey or under the laws
of the United States.

     A "qualified investment fund", as defined by applicable New Jersey law, is
any investment company or trust registered with the Securities Exchange
Commission, or any series of such investment company or trust, which, for the
calendar year in which the distribution is paid, (a) has no investments other
than interest-bearing obligations, obligations issued at a discount, and cash
and cash items, including receivables, and financial options, futures, forward
contracts, or other similar financial instruments related to interest-bearing
obligations, obligations issued at a discount or bond indexes related thereto;
and (b) has not less than 80% of the aggregate principal amount of all its
investments, excluding financial options, futures, forward contracts, or other
similar financial instruments related to interest-bearing obligations,
obligations issued at a discount or bond indexes related thereto to the extent
such instruments are authorized by section 851(b) of the federal Internal
Revenue Code, 26 U.S.C.  Section  851(b), cash and cash items (including
receivables), in obligations of the types described in the preceding paragraph.
Failure to satisfy the "80% investment test" described in clause (b) of the
preceding sentence, even if necessary to maintain a "defensive" position, would
cause all distributions from the New Jersey Series to be included in the gross
income of shareholders for purposes of calculating the New Jersey gross income
tax.

     The foregoing exclusion applies only to shareholders who are individuals,
estates, and trusts, subject to the New Jersey gross income tax. That tax does
not apply to corporations, and while certain qualifying distributions are
exempt from corporation income tax, all distributions will be reflected in the
net income tax base for purposes of computing the corporation business tax.

     The New Jersey Series will notify shareholders by February 15 of each
calendar year as to the portion of its distributions for the preceding calendar
year that is exempt from federal income and New Jersey income taxes.

     THE NEW YORK SERIES -- SPECIAL TAX CONSIDERATIONS. Under existing New York
law, individual shareholders who are New York residents will not incur any
federal, New York State or New York City income tax on the amount of
exempt-interest dividends received by them from the Series which represents a
distribution of income from New York tax-exempt securities whether taken in
cash or reinvested in additional shares.


                                       64
<PAGE>

     Exempt-interest dividends are included, however, in determining what
portion, if any, of a person's Social Security benefits are subject to federal
income tax.

     Interest on indebtedness incurred or continued to purchase or carry shares
of an investment company paying exempt-interest dividends, such as the Fund,
may not be deductible by the investor for State or City personal income tax
purposes.

     Shareholders will normally be subject to federal, New York State or New
York City income tax on dividends paid from interest income derived from
taxable securities and on distributions of net capital gains. For federal and
New York State or New York City income tax purposes, distributions of net
long-term capital gains, if any, are taxable to shareholders as long-term
capital gains, regardless of how long the shareholder has held the Fund shares
and regardless of whether the distribution is received in additional shares or
in cash. Distributions from investment income and capital gains, including
exempt-interest dividends, may be subject to New York franchise taxes if
received by a corporation doing business in New York, to state taxes in states
other then New York and to local taxes.

     THE OHIO SERIES -- SPECIAL TAX CONSIDERATIONS. Under existing Ohio law,
provided the Ohio Series qualifies as a "regulated investment company" under
the Code, the Ohio Series will not be subject to the Ohio personal income tax,
the Ohio corporation franchise tax, or to income taxes imposed by
municipalities and other political subdivisions in Ohio. Individual
shareholders of the Ohio Series who are subject to the Ohio personal income
taxes will not be subject to such taxes on distributions with respect to shares
of the Ohio Series to the extent that such distributions are directly
attributable to interest on obligations issued by the State of Ohio, its
counties and municipalities, authorities, instrumentalities or other political
subdivisions ("Ohio Obligations"). Corporate shareholders of the Ohio Series
that are subject to the Ohio corporation franchise tax computed on the net
income basis will not be subject to such tax on distributions with respect to
shares of the Ohio Series to the extent that such distributions either (a) are
attributable to interest on Ohio obligations, or (b) represent "exempt-interest
dividends" as defined in Section 852 of the Code. Shares of the Ohio Series
will, however, be included in a corporate shareholder's tax base for purposes
of computing the Ohio corporation franchise tax on the net worth basis.

     Distributions with respect to the Ohio Series that are attributable to
interest on obligations of the United States or its territories or possessions
(including the Governments of Puerto Rico, the Virgin Islands, and Guam), or of
any authority, commission or instrumentality of the United States that is
exempt from state income taxes under the laws of the United States, will not be
subject to the Ohio personal income tax, the Ohio corporation franchise tax (to
the extent computed on the net income basis), or to taxes imposed by
municipalities and other political subdivisions in Ohio.

     Capital gains distributed by the Ohio Series attributable to any profits
made on the sale, exchange, or other disposition by the Ohio Series of Ohio
Obligations will not be subject to the Ohio personal income tax, the Ohio
corporation franchise tax (to the extent computed on the net income basis), or
to taxes imposed by municipalities and other political subdivisions in Ohio.

     Interest on indebtedness incurred or continued (directly or indirectly) by
a shareholder of the Ohio Series to purchase or carry shares of the Ohio Series
will not be deductible for Ohio personal income tax purposes.

     THE PENNSYLVANIA SERIES -- SPECIAL TAX CONSIDERATIONS. Individual
shareholders of the Pennsylvania Series resident in the Commonwealth of
Pennsylvania will not be subject to Pennsylvania personal income tax on
distributions received from the Pennsylvania Series to the extent such
distributions are attributable to interest on tax-exempt obligations of the
Commonwealth, its agencies, authorities and political subdivisions or
obligations of the United States or of the Governments of Puerto Rico, the
Virgin Islands and Guam. Other distributions from the Pennsylvania Series,
including capital gains generally and interest on securities not described in
the preceding sentence, generally will not be exempt from Pennsylvania Personal
Income Tax.

     Other than the School District of Philadelphia, political subdivisions of
the Commonwealth have not been authorized to impose an unearned income tax upon
resident individuals. Individual shareholders


                                       65
<PAGE>

who reside in the Philadelphia School District will not be subject to the
School District Unearned Income Tax on (i) distributions received from the
Pennsylvania Series to the extent that such distributions are exempt from
Pennsylvania Personal Income Tax, or (ii) distributions of capital gains income
by the Pennsylvania Series.

     Corporate shareholders who are subject to the Pennsylvania Corporate Net
Income Tax will not be subject to that tax on distributions by the Pennsylvania
Series that qualify as "exempt-interest dividends" under Section 852(b)(5) of
the U.S. Internal Revenue Code or are attributable to interest on obligations
of the United States or agencies or instrumentalities thereof. For Capital
Stock/Foreign Franchise Tax purposes, corporate shareholders must normally
reflect their investment in the Pennsylvania Series and the dividends received
thereon in the determination of the taxable value of their capital stock.

     The Pennsylvania Series will not be subject to Corporate Net Income Tax or
other corporate taxation in Pennsylvania.

     A Pennsylvania statute purports to authorize most counties to impose a tax
on intangible personal property of their residents. Although this tax is
presently under constitutional challenge in the courts, some counties may
attempt to levy the tax. Shares in the Pennsylvania Series constitute
intangible personal property. However, shares in the Pennsylvania Series will
not be subject to intangible personal property taxation to the extent that the
intangible personal property owned in the portfolio of the Pennsylvania Series
would not be subject to such taxation if owned directly by a resident of
Pennsylvania. The Pennsylvania Series will invest predominantly in obligations
of the Commonwealth, its agencies, authorities and political subdivisions, or
obligations of the United States or the Governments of Puerto Rico, the Virgin
Islands or Guam, which obligations are not subject to intangible personal
property taxation in Pennsylvania. Only the fraction, if any, of the value of
the Pennsylvania Series' portfolio not invested in securities described in the
preceding sentence would be subject to any applicable intangible personal
property tax.

X. UNDERWRITERS
- --------------------------------------------------------------------------------

     The shares of each Series are offered to the public on a continuous basis.
The Distributor, as the principal underwriter of the shares, has certain
obligations under the Distribution Agreement concerning the distribution of the
shares. These obligations and the compensation the Distributor receives are
described above in the sections titled "Principal Underwriter" and "Rule 12b-1
Plans."

XI. CALCULATION OF PERFORMANCE DATA
- --------------------------------------------------------------------------------


     As discussed in the Prospectus, from time to time each Series of the Fund
may quote its "yield" and/or its "total return" in advertisements and sales
literature. The yield of each Series is calculated for any 30-day period as
follows: the amount of interest income for each security in a particular
Series' portfolio is determined in accordance with regulatory requirements; the
total for the entire portfolio constitutes the Series' gross income for the
period. Expenses accrued during the period are subtracted to arrive at "net
investment income". The resulting amount is divided by the product of the net
asset value per share of that Series on the last day of the period multiplied
by the average number of the Series' shares outstanding during the period that
were entitled to dividends. This amount is added to 1 and raised to the sixth
power. 1 is then subtracted from the result and the difference is multiplied by
2 to arrive at the annualized yield. For the 30 day period ended November 30,
1999, the yields, calculated pursuant to the formula described above, for the
Arizona Series, the California Series, the Florida Series, the Massachusetts
Series, the Michigan Series, the Minnesota Series, the New Jersey Series, the
New York Series, the Ohio Series and the Pennsylvania Series were 4.49%, 4.79%,
4.47%, 4.47%, 4.29%, 3.99%, 4.62%, 4.45%, 3.86% and 4.76% respectively.


     To determine interest income from debt obligations, a yield-to-maturity,
expressed as a percentage, is determined for obligations held at the beginning
of the period, based on the current market value of the security plus accrued
interest, generally as of the end of the month preceding the 30-day period, or,
for obligations purchased during the period, based on the cost of the security
(including accrued interest). The yield-to-maturity is multiplied by the market
value (plus accrued interest) for each security and the


                                       66
<PAGE>

result is divided by 360 and multiplied by 30 days or the number of days the
security was held during the period, if less. Modifications are made for
determining yield-to-maturity on certain tax-exempt securities.



     Each Series of the Fund may also quote a "tax-equivalent yield" determined
by dividing the tax- exempt portion of the quoted yield by 1 minus the stated
income tax rate and adding the result to the portion of the yield that is not
tax-exempt. The tax-equivalent yield for the Arizona Series, the California
Series, the Florida Series, the Massachusetts Series, the Michigan Series, the
Minnesota Series, the New Jersey Series, the New York Series, the Ohio Series
and the Pennsylvania Series based upon a combined Federal and respective State
personal income tax bracket of 42.64%, 45.22%, 39.60%, 43.19%, 42.26%, 44.73%,
43.45%, 43.74%, 43.70% and 41.29% respectively for the 30 day period ended
November 30, 1999, were 7.83%, 8.74%, 7.40%, 7.87%, 7.43%, 7.22%, 8.17%, 7.91%,
6.86% and 8.11% respectively, based upon the respective yields quoted above.


     Each Series' "average annual total return" represents an annualization of
that Series' total return over a particular period and is computed by finding
the annual percentage rate which will result in the ending redeemable value of
a hypothetical $1,000 investment made at the beginning of a one, five or ten
year period, or for the period from the date of commencement of the Fund's
operations, if shorter than any of the foregoing. For the purpose of this
calculation, it is assumed that all dividends and distributions are reinvested.
The formula for computing the average annual total return involves a percentage
obtained by dividing the ending redeemable value by the amount of the initial
investment (which is reduced by the initial sales charge), taking a root of the
quotient (where the root is equivalent to the number of years in the period)
and subtracting 1 from the result.


     The average annual total returns of the Arizona Series, California Series,
the Florida Series, the Massachusetts Series, the Michigan Series, the
Minnesota Series, the New Jersey Series, the New York Series, the Ohio Series
and the Pennsylvania Series for the fiscal year ended November 30, 1999, for
the five years ended November 30, 1999 and for the period January 15, 1991
(commencement of operations) (April 30, 1991 for the Arizona Series) through
November 30, 1999 were:

     In addition to the foregoing, each Series of the Fund may advertise its
total return over different periods of time by means of aggregate, average,
year-by-year or other types of total return figures. Such calculations may or
may not reflect the imposition of the maximum front-end sales charge, which, if
reflected would reduce the performance quoted. For example, the average annual
total return of each Series of the Fund may be calculated in the manner
described above but without the deduction for any applicable sales charge.


     Based on this calculation, the average annual total returns (without
deduction for applicable sales charge) for the Arizona Series, the California
Series, the Florida Series, the Massachusetts Series, the Michigan Series, the
Minnesota Series, the New Jersey Series, the New York Series, the Ohio Series

     In addition, the Fund may compute its aggregate total return for specified
periods by determining the aggregate percentage rate which will result in the
ending value of a hypothetical $1,000 investment made at the beginning of the
period. For the purpose of this calculation, it is assumed that all dividends
and distributions are reinvested. The formula for computing aggregate total
return involves a percentage obtained by dividing the ending value (without
reduction for any sales charge) by the initial $1,000 investment and
subtracting 1 from the result. Based on the foregoing calculation, the total
returns for the fiscal year ended November 30, 1999, for the five years ended
November 30, 1999 and for the period January 15, 1991 (April 30, 1991 for the
Arizona Series) through November 30, 1999 were:

MORGAN STANLEY DEAN WITTER MULTI-STATE MUNICIPAL SERIES TRUST
NOTES TO FINANCIAL STATEMENTS November 30, 1999



1. ORGANIZATION AND ACCOUNTING POLICIES

Morgan Stanley Dean Witter Multi-State Municipal Series Trust (the "Fund") is
registered under the Investment Company Act of 1940, as amended (the "Act"), as
a non-diversified, open-end management investment company. The investment
objective of each Series is to provide a high level of current income exempt
from both Federal and the designated state income taxes consistent with
preservation of capital.

The Fund, organized on October 29, 1990, as a Massachusetts business trust, is
comprised of ten separate Series (the "Series"): the Arizona Series, the
California Series, the Florida Series, the Massachusetts Series, the Michigan
Series, the Minnesota Series, the New Jersey Series, the New York Series, the
Ohio Series and the Pennsylvania Series. Each of the Series commenced
operations on January 15, 1991, with the exception of the Arizona Series which
commenced operations on April 30, 1991.

The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts and disclosures. Actual results could differ
from those estimates.

The following is a summary of significant accounting policies:


A. VALUATION OF INVESTMENTS -- Portfolio securities are valued by an outside
independent pricing service approved by the Fund's Trustees. The pricing
service has informed the Fund that in valuing the portfolio securities, it uses
both a computerized matrix of tax-exempt securities and evaluations by its
staff, in each case based on information concerning market transactions and
quotations from dealers which reflect the bid side of the market each day. The
portfolio securities are thus valued by reference to a combination of
transactions and quotations for the same or other securities believed to be
comparable in quality, coupon, maturity, type of issue, call provisions,
trading characteristics and other features deemed to be relevant. Short-term
debt securities having a maturity date of more than sixty days at time of
purchase are valued on a mark-to-market basis until sixty days prior to
maturity and thereafter at amortized cost based on their value on the 61st day.
Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.


B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Discounts are accreted and premiums are amortized over the life of the
respective securities. Interest income is accrued daily.

MORGAN STANLEY DEAN WITTER MULTI-STATE MUNICIPAL SERIES TRUST
NOTES TO FINANCIAL STATEMENTS November 30, 1999, continued

C. FEDERAL INCOME TAX STATUS -- It is the Fund's policy to comply individually
for each Series with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its taxable and
nontaxable income to its shareholders. Accordingly, no federal income tax
provision is required.

D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends
and distributions to its shareholders on the record date. The amount of
dividends and distributions from net investment income and net realized capital
gains are determined in accordance with federal income tax regulations which
may differ from generally accepted accounting principles. These "book/tax"
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the capital accounts based on their federal tax-basis treatment;
temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for financial reporting purposes but not for tax purposes are reported as
dividends in excess of net investment income or distributions in excess of net
realized capital gains. To the extent they exceed net investment income and net
realized capital gains for tax purposes, they are reported as distributions of
paid-in-capital.

E. EXPENSES -- Direct expenses are charged to the respective Series and general
corporate expenses are allocated on the basis of relative net assets or equally
among the Series.

2. INVESTMENT MANAGEMENT AGREEMENT

Pursuant to an Investment Management Agreement, each Series of the Fund pays
Morgan Stanley Dean Witter Advisors Inc. (the "Investment Manager") a
management fee, accrued daily and payable monthly, by applying the annual rate
of 0.35% to the daily net assets of each Series determined as of the close of
each business day.

Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes office space and facilities, equipment, clerical,
bookkeeping and certain legal services, and pays the salaries of all personnel,
including officers of the Fund who are employees of the Investment Manager. The
Investment Manager also bears the cost of telephone services, heat, light,
power and other utilities provided to the Fund.

3. PLAN OF DISTRIBUTION

Morgan Stanley Dean Witter Distributors Inc. (the "Distributor"), an affiliate
of the Investment Manager, is the distributor of the Fund's shares and, in
accordance with a Plan of Distribution (the "Plan") pursuant to Rule 12b-1
under the Act, finances certain expenses in connection with the distribution of
shares of the Fund.

Under the Plan, the expenses of certain activities and services provided by
Dean Witter Reynolds Inc. ("DWR"), an affiliate of the Investment Manager and
Distributor, and others who engage in or support distribution of the Fund's
shares or who service shareholder accounts, including overhead and telephone
expenses incurred in connection with the distribution of the Fund's shares, are
reimbursed.

Reimbursements for these expenses will be made in monthly payments by the Fund
to the Distributor, which will in no event exceed an amount equal to a payment
at the annual rate of 0.15% of the Fund's average daily net assets during the
month. Expenses incurred by the Distributor pursuant to the Plan in any fiscal
year will not be reimbursed by the Fund through payments accrued in any
subsequent fiscal year. For the year ended November 30, 1999, the distribution
fees were accrued at the following annual rates:

MORGAN STANLEY DEAN WITTER MULTI-STATE MUNICIPAL SERIES TRUST
REPORT OF INDEPENDENT ACCOUNTANTS



TO THE SHAREHOLDERS AND TRUSTEES

OF MORGAN STANLEY DEAN WITTER MULTI-STATE MUNICIPAL SERIES TRUST

In our opinion, the accompanying statements of assets and liabilities,
including the portfolios of investments, and the related statements of
operations and of changes in net assets and the financial highlights present
fairly, in all material respects, the financial position of the Arizona Series,
the California Series, the Florida Series, the Massachusetts Series, the
Michigan Series, the Minnesota Series, the New Jersey Series, the New York
Series, the Ohio Series, and the Pennsylvania Series (constituting the Morgan
Stanley Dean Witter Multi-State Municipal Series Trust, hereafter referred to
as the "Fund") at November 30, 1999, the results of each of their operations
for the year then ended, the changes in each of their net assets for each of
the two years in the period then ended and the financial highlights for each of
the five years in the period then ended, in conformity with generally accepted
accounting principles. These financial statements and financial highlights
(hereafter referred to as "financial statements") are the responsibility of the
Fund's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
financial statements in accordance with generally accepted auditing standards
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at November 30, 1999 by correspondence with the
custodian and brokers, provide a reasonable basis for the opinion expressed
above.

As described in Note 6 to the financial statements, the Fund's Trustees have
approved reorganization plans whereby the Massachusetts Series, the Michigan
Series, the Minnesota Series and the Ohio Series would each be merged into
Morgan Stanley Dean Witter Tax-Exempt Securities Trust, the California Series
would be merged into Morgan Stanley Dean Witter California Tax-Free Income Fund
and the New York Series would be merged into Morgan Stanley Dean Witter New
York Tax-Free Income Fund. Each respective Plan is subject to the consent of
the respective Series' shareholders.

RATINGS OF INVESTMENTS


MOODY'S INVESTORS SERVICE INC. ("MOODY'S")

                            MUNICIPAL BOND RATINGS

Aaa Bonds which are rated Aaa are judged to be of the best quality. They carry
    the smallest degree of investment risk and are generally referred to as
    "gilt edge." Interest payments are protected by a large or by an
    exceptionally stable margin and principal is secure. While the various
    protective elements are likely to change, such changes as can be
    visualized are most unlikely to impair the fundamentally strong position
    of such issues.

Aa  Bonds which are rated Aa are judged to be of high quality by all standards.
    Together with the Aaa group they comprise what are generally known as high
    grade bonds. They are rated lower than the best bonds because margins of
    protection may not be as large as in Aaa securities or fluctuation of
    protective elements may be of greater amplitude or there may be other
    elements present which make the long-term risks appear somewhat larger
    than in Aaa securities.

A   Bonds which are rated A possess many favorable investment attributes and
    are to be considered as upper medium grade obligations. Factors giving
    security to principal and interest are considered adequate, but elements
    may be present which suggest a susceptibility to impairment sometime in
    the future.

Baa Bonds which are rated Baa are considered as medium grade obligation; i.e.,
    they are neither highly protected nor poorly secured. Interest payments
    and principal security appear adequate for the present but certain
    protective elements may be lacking or may be characteristically unreliable
    over any great length of time. Such bonds lack outstanding investment
    characteristics and in fact have speculative characteristics as well.

    Bonds rated Aaa, Aa, A and Baa are considered investment grade bonds.

Ba  Bonds which are rated Ba are judged to have speculative elements; their
    future cannot be considered as well assured. Often the protection of
    interest and principal payments may be very moderate, and therefore not
    well safeguarded during both good and bad times over the future.
    Uncertainty of position characterizes bonds in this class.

B   Bonds which are rated B generally lack characteristics of a desirable
    investment. Assurance of interest and principal payments or of maintenance
    of other terms of the contract over any long period of time may be small.

Caa Bonds which are rated Caa are of poor standing. Such issues may be in
    default or there may be present elements of danger with respect to
    principal or interest.

Ca  Bonds which are rated Ca present obligations which are speculative in a
    high degree. Such issues are often in default or have other marked
    shortcomings.

C   Bonds which are rated C are the lowest rated class of bonds, and issues so
    rated can be regarded as having extremely poor prospects of ever attaining
    any real investment standing.

    Conditional Rating: Bonds for which the security depends upon the
completion of some act of the fulfillment of some condition are rated
conditionally. These are bonds secured by (a) earnings of projects under
construction, (b) earnings of projects unseasoned in operation experience, (c)
rentals which begin when facilities are completed, or (d) payments to which
some other limiting condition attaches. Parenthetical rating denotes probable
credit stature upon completion of construction or elimination of basis of
condition.

     Rating Refinements: Moody's may apply numerical modifiers, 1, 2 and 3 in
each generic rating classification from Aa through B in its municipal bond
rating system. The modifier 1 indicates a mid- range ranking; and a modifier 3
indicates that the issue ranks in the lower end of its generic rating category.

                            MUNICIPAL NOTE RATINGS

     Moody's ratings for state and municipal notes and other short-term loans
are designated Moody's Investment Grade (MIG). MIG 1 denotes best quality and
means there is present strong protection from established cash flows, superior
liquidity support or demonstrated broad-based access to the market for
refinancing. MIG 2 denotes high quality and means that margins of protection
are ample although not as large as in MIG 1. MIG 3 denotes favorable quality
and means that all security elements are accounted for but that the undeniable
strength of the previous grades, MIG 1 and MIG 2, is lacking. MIG 4 denotes
adequate quality and means that the protection commonly regarded as required of
an investment security is present and that while the notes are not distinctly
or predominantly speculative, there is specific risk.


                       VARIABLE RATE DEMAND OBLIGATIONS

     A short-term rating, in addition to the Bond or MIG ratings, designated
VMIG may also be assigned to an issue having a demand feature. The assignment
of the VMIG symbol reflects such characteristics as payment upon periodic
demand rather than fixed maturity dates and payment relying on external
liquidity. The VMIG rating criteria are identical to the MIG criteria discussed
above.


                           COMMERCIAL PAPER RATINGS

     Moody's Commercial Paper ratings are opinions of the ability to repay
punctually promissory obligations not having an original maturity in excess of
nine months. These ratings apply to Municipal commercial Paper as well as
taxable Commercial Paper. Moody's employs the following three designations, all
judged to be investment grade, to indicate the relative repayment capacity of
rated issuers: Prime-1, Prime-2, Prime-3.

     Issuers rated Prime-1 have a superior capacity for repayment of short-term
promissory obligations. Issuers rated Prime-2 have a strong capacity for
repayment of short-term promissory obligations; and Issuers rated Prime-3 have
an acceptable capacity for repayment of short-term promissory obligations.
Issuers rated Not Prime do not fall within any of the Prime rating categories.


STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S")


                            MUNICIPAL BOND RATINGS

     A Standard & Poor's municipal rating is a current assessment of the
creditworthiness of an obligor with respect to a specific obligation. This
assessment may take into consideration obligors such as guarantors, insurers,
or lessees.

     The ratings are based on current information furnished by the issuer or
obtained by Standard & Poor's from other sources it considers reliable. The
ratings are based, in varying degrees, on the following considerations: (1)
likelihood of default-capacity and willingness of the obligor as to the timely
payment of interest and repayment of principal in accordance with the terms of
the obligation; (2) nature of and provisions of the obligation; and (3)
protection afforded by, and relative position of, the obligation in the event
of bankruptcy, reorganization or other arrangement under the laws of bankruptcy
and other laws affecting creditors' rights.

     Standard & Poor's does not perform an audit in connection with any rating
and may, on occasion, rely on unaudited financial information. The ratings may
be changed, suspended or withdrawn as a result of changes in, or unavailability
of, such information, or for other reasons.

AAA Debt rated "AAA" has the highest rating assigned by Standard & Poor's.
    Capacity to pay interest and repay principal is extremely strong.

AA  Debt rated "AA" has a very strong capacity to pay interest and repay
    principal and differs from the highest-rated issues only in small degree.


                                      117
<PAGE>

A   Debt rated "A" has a strong capacity to pay interest and repay principal
    although they are somewhat more susceptible to the adverse effects of
    changes in circumstances and economic conditions than debt in higher-rated
    categories.

BBB Debt rated "BBB" is regarded as having an adequate capacity to pay
    interest and repay principal. Whereas it normally exhibits adequate
    protection parameters, adverse economic conditions or changing
    circumstances are more likely to lead to a weakened capacity to pay
    interest and repay principal for debt in this category than for debt in
    higher-rated categories.

    Bonds rated AAA, AA, A and BBB are considered investment grade bonds.

BB  Debt rated "BB" has less near-term vulnerability to default than other
    speculative grade debt. However, it faces major ongoing uncertainties or
    exposure to adverse business, financial or economic conditions which could
    lead to inadequate capacity to meet timely interest and principal payment.

B   Debt rated "B" has a greater vulnerability to default but presently has the
    capacity to meet interest payments and principal repayments. Adverse
    business, financial or economic conditions would likely impair capacity or
    willingness to pay interest and repay principal.

CCC Debt rated "CCC" has a current identifiable vulnerability to default, and
    is dependent upon favorable business, financial and economic conditions to
    meet timely payments of interest and repayments of principal. In the event
    of adverse business, financial or economic conditions, it is not likely to
    have the capacity to pay interest and repay principal.

CC  The rating "CC" is typically applied to debt subordinated to senior debt
    which is assigned an actual or implied "CCC" rating.

C   The rating "C" is typically applied to debt subordinated to senior debt
    which is assigned an actual or implied "CCC" debt rating.

Cl  The rating "Cl" is reserved for income bonds on which no interest is being
    paid.

D   Debt rated "D" is in payment default. The `D' rating category is used when
    interest payments or principal payments are not made on the date due even
    if the applicable grace period has not expired, unless S&P believes that
    such payments will be made during such grace period. The `D' rating also
    will be used upon the filing of a bankruptcy petition if debt service
    payments are jeopardized.

NR  Indicates that no rating has been requested, that there is insufficient
    information on which to base a rating or that Standard & Poor's does not
    rate a particular type of obligation as a matter of policy.

    Bonds rated "BB", "B", "CCC", "CC" and "C" are regarded as having
    predominantly speculative characteristics with respect to capacity to pay
    interest and repay principal. "BB" indicates the least degree of
    speculation and "C" the highest degree of speculation. While such debt
    will likely have some quality and protective characteristics, these are
    outweighed by large uncertainties or major risk exposures to adverse
    conditions.

    Plus (+) or minus (-): The ratings from "AA" to "CCC" may be modified by
    the addition of a plus or minus sign to show relative standing within the
    major ratings categories.

    The foregoing ratings are sometimes followed by a "p" which indicates that
    the rating is provisional. A provisional rating assumes the successful
    completion of the project being financed by the bonds being rated and
    indicates that payment of debt service requirements is largely or entirely
    dependent upon the successful and timely completion of the project. This
    rating, however, while addressing credit quality subsequent to completion
    of the project, makes no comment on the likelihood or risk of default upon
    failure of such completion.

                            MUNICIPAL NOTE RATINGS


     Commencing on July 27, 1984, Standard & Poor's instituted a new rating
category with respect to certain municipal note issues with a maturity of less
than three years. The new note ratings denote the following:


     SP-1 denotes a very strong or strong capacity to pay principal and
          interest. Issues determined to possess overwhelming safety
          characteristics are given a plus (+) designation (SP-1+).


     SP-2 denotes a satisfactory capacity to pay principal and interest.


     SP-3 denotes a speculative capacity to pay principal and interest.


                           COMMERCIAL PAPER RATINGS

     Standard and Poor's commerical paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more
than 365 days. The commercial paper rating is not a recommendation to purchase
or sell a security. The ratings are based upon current information furnished by
the issuer or obtained by S&P from other sources it considers reliable. The
ratings may be changed, suspended, or withdrawn as a result of changes in or
unavailability of such information. Ratings are graded into group categories,
ranging from "A" for the highest quality obligations to "D" for the lowest.
Ratings are applicable to both taxable and tax-exempt commercial paper. The
categories are as follows:

     Issues assigned A ratings are regarded as having the greatest capacity for
timely payment. Issues in this category are further refined with the
designation 1, 2 and 3 to indicate the relative degree of safety.

A-1 indicates that the degree of safety regarding timely payments is very
strong.

A-2 indicates capacity for timely payment on issues with this designation is
strong. However, the relative degree of safety is not as overwhelming as for
issues designated "A-1".

A-3 indicates a satisfactory capacity for timely payment. Obligations carrying
this designation are, however, somewhat more vulnerable to the adverse effects
of changes in circumstances than obligations carrying the higher designations.

Morgan Stanley Dean Witter Tax-Exempt Securities Trust
Two World Trade Center
New York, New York 10048

Ladies and Gentlemen:


        This opinion is being furnished to Morgan Stanley Dean Witter Tax-Exempt
Securities Trust, a Massachusetts business trust ("Tax-Exempt"), in connection
with the Registration Statement on Form N-14 (the "Registration Statement")
under the Securities Act of 1933, as amended (the "1933 Act"), to be filed by
Tax-Exempt in connection with the acquisition by Tax-Exempt, of substantially
all the assets of Minnesota Series, a portfolio of Morgan Stanley Dean Witter
Multi-State Municipal Series Trust, a Massachusetts business trust ("Minnesota
Series"), in exchange for shares of beneficial interest of Tax-Exempt ("Shares")
and the assumption by Tax-Exempt of certain stated liabilities of Minnesota
Series pursuant to an Agreement and Plan of Reorganization dated as of January
26, 2000 (the "Reorganization Agreement"). We have examined such statutes,
regulations, corporate records and other documents and reviewed such questions
of law as we deemed necessary or appropriate for the purposes of this opinion.

        As to matters of Massachussetts law contained in this opinion, we have
relied upon the opinion of Lane Altman & Owens LLP, dated March 2, 2000.

        Based upon the foregoing, we are of the opinion that the Shares when
issued, as described in the Reorganization Agreement, will be duly authorized
and, assuming receipt of the consideration to be paid therefor, upon delivery
as provided in the Reorganization Agreement, will be legally issued, fully paid
and non-assessable (except for the potential liability of shareholders described
in Tax-Exempt's Statement of Additional Information dated May 1, 1999 under the
caption "Capital Stock And Other Securities").

        We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us under the caption "Legal
Matters" in the Prospectus forming a part of the Registration Statement. We do
not thereby admit that we are within the category of persons whose consent is
required under Section 7 of the 1933 Act or the rules and regulations of the
Securities and Exchange Commission thereunder.


                                  Very truly yours,

Dear Sirs:

        We understand that the trustees of Morgan Stanley Dean Witter Tax-Exempt
Securities Trust, a Massachusetts business trust (the "Trust"), intend, on or
about March 2, 2000, to cause to be filed on behalf of the Trust a Registration
Statement on Form N-14 (the "Registration Statement") in connection with the
acquisition (the "Acquisition") by the Trust of substantially all the assets of
the Minnesota Series ("Minnesota Series") portfolio of Morgan Stanley Dean
Witter Multi-State Municipal Series Trust ("MSDW Multi-State"), in exchange for
shares of beneficial interest of the Trust (the AShares@), and the assumption by
the Trust of certain stated liabilities of Minnesota Series pursuant to an
Agreement and Plan of Reorganization dated as of January 26, 2000 (the
"Agreement"). We further understand that the Shares will be issued pursuant to
the Agreement.

        You have requested that we act as special counsel to the Trust with
respect to the laws of the Commonwealth of Massachusetts on certain specified
matters, and in such capacity we are furnishing you with this opinion. You have
not asked for, and we do not offer, an opinion on any other matter or
transaction related to the Trust, Minnesota Series, MSDW Multi-State, the
Acquisition, the Agreement or any matter related thereto, except as specifically
set forth below.

        The Trust is a business trust created under an Agreement and Declaration
of Trust finally executed, delivered and filed in Boston, Massachusetts on April
6, 1987 (as amended from time to time, the "Trust Agreement"). The Trustees of
the Trust (as defined in the Trust Agreement) (the "Trustees") have the powers
set forth in the Trust Agreement, subject to the terms, provisions and
conditions provided therein.

        In connection with our opinions delivered herein, we have examined the
following items some of which have been provided to us by, or on behalf of, you:
(i) a copy of the Agreement in the form to be executed by the Trust; (ii) a copy
of the Trust Agreement; (iii) a copy of the Amended and Restated By-laws of the
Trust effective as of May 1, 1999; (iv) a Certificate of Legal Existence for the
Trust provided by the Secretary of State of the Commonwealth of Massachusetts
dated February 16, 2000; and (v) copies of the Registration Statement on Form
N-14 to be filed by the Trust and the Trust's current Prospectus and Statement
of Additional Information.

                                                             March 2, 2000

        In rendering this opinion we have assumed, without independent
verification, (i) the due authority of all individuals signing in representative
capacities and the genuineness of signatures, (ii) the authenticity,
completeness and continued effectiveness of all documents or copies furnished to
us, (iii) that resolutions approving the Registration Statement, the Acquisition
and the Agreement have been duly adopted by the Trustees, (iv) that no
amendments, agreements, resolutions or actions have been approved, executed or
adopted which would limit, supersede or modify the items described above, and
(v) that the by-laws filed as an exhibit to the Registration Statement have been
duly adopted by the Trustees. We have also examined such questions of law as we
have concluded necessary or appropriate for purposes of the opinions expressed
below. Where documents are referred to in resolutions approved by the Trustees,
or in the Registration Statement, we assume such documents are the same as in
the most recent form provided to us, whether as an exhibit to the Registration
Statement, or otherwise. When any opinion set forth below relates to the
existence or standing of the Trust, such opinion is based entirely upon and is
limited by the items referred to above. We understand that the foregoing
assumptions, limitations and qualifications are acceptable to you.

        Based upon the foregoing, and with respect to Massachusetts law only
(except that no opinion is herein expressed with respect to compliance with the
Massachusetts Uniform Securities Act), to the extent that Massachusetts law may
be applicable, and without reference to the laws of any of the other several
states or of the United States of America, including State and Federal
securities laws, we are of the opinion that:

        1. The Trust is a business trust with transferable shares, organized in
compliance with the requirements of The Commonwealth of Massachusetts, and the
Trust Agreement is legal and valid.

        2. The Shares to be issued as described in the Registration Statement,
including any Exhibits thereto, have been duly authorized and, assuming receipt
of the consideration to be paid therefor, upon delivery as provided in the
Agreement, will be validly issued, fully paid and nonassessable (except for the
potential liability of shareholders described in the Trust's current Statement
of Additional Information under the caption "Capital Stock and Other
Securities").

        We understand that you will rely on this opinion solely in connection
with your opinion to be filed with the Securities and Exchange Commission as an
exhibit to the Registration Statement. We hereby consent to such use of this
opinion and we also consent to the filing of said opinion with the Securities
and Exchange Commission. In so consenting, we do not thereby

                  Re:  Agreement and Plan of Reorganization for the Exchange
                       of Stock of Morgan Stanley Dean Witter Tax-Exempt
                       Securities Trust for Substantially All of the Assets
                       of Minnesota Series, a portfolio of Morgan Stanley
                       Dean Witter Multi-State Municipal Series Trust, dated
                       as of January 26, 2000 (the "Reorganization
                       Agreement").

Ladies and Gentlemen:

         We have acted as counsel to Minnesota Series ("Minnesota Series"), a
portfolio of Morgan Stanley Dean Witter Multi-State Municipal Series Trust
("Multi-State"), and Morgan Stanley Dean Witter Tax-Exempt Securities Trust
("Tax-Exempt") in connection with the proposed transfer of substantially all of
the assets of Minnesota Series to Tax-Exempt and certain other transactions
related thereto pursuant to and in accordance with the terms of the
Reorganization Agreement (the "Reorganization"). You have requested that we
provide an opinion regarding the treatment of the Reorganization under the
Internal Revenue Code of 1986, as amended (the "Code"), and the accuracy of the
tax disclosures in the proxy statement/prospectus (the "Proxy
Statement/Prospectus") on Exhibit 12 to the Form N-14 Registration Statement.

         In connection with rendering this opinion, we have examined originals
or copies, certified or otherwise identified to our satisfaction, of (i) the
Reorganization Agreement, (ii) the Registration Statement on Form N-14 for the
Reorganization, and the Proxy Statement/Prospectus and other documents,
exhibits, attachments and schedules contained therein, (iii) written
representations of Morgan Stanley Dean Witter Advisors Inc. (the "Advisor")
concerning certain facts underlying and relating to the Reorganization set forth
in a letter dated March 1, 2000, and (iv) such other documents and materials as
we have deemed necessary or appropriate for purposes of the opinions set forth
below. In our examination, we have assumed the genuineness of all signatures,
the legal capacity of all natural persons, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified or photostatic copies, and the
authenticity of the originals of such copies. We have not made an independent
investigation of the facts set forth either in the Registration Statement, the
Reorganization Agreement or such other documents that we have examined. We have
consequently assumed in rendering this opinion that the information presented in
such documents or otherwise furnished to us accurately and completely describes
in all material respects all facts relevant to the Reorganization.

         We have also assumed for purposes of rendering our opinion (i) the
accuracy of, and material compliance with, the representations of the Advisor
set forth in the letter referred to


<PAGE>

above, (ii) the accuracy of, and material compliance with, the representations,
warranties, covenants and agreements of Tax-Exempt and Multi-State, on behalf of
Minnesota Series, made in the Reorganization Agreement, and (iii) that there are
no agreements or understandings other than those of which we have been informed
that would affect our conclusions set forth below.

         The opinion set forth below is based on the Code, the legislative
history with respect thereto, rules and regulations promulgated thereunder, and
published rulings, court decisions and administrative authorities issued with
respect to all of the foregoing, all as in effect and existing on the date
hereof, and all of which are subject to change at any time, possibly on a
retroactive basis. In addition, there can be no assurance that positions
contrary to those stated in our opinion may not be asserted by the Internal
Revenue Service.

         Any change occurring after the date hereof in, or a variation from, any
of the foregoing factual or legal bases for our opinion could affect the
conclusions set forth below.

         In addition, the opinion expressed herein is given as of the date
hereof and we express no obligation to advise you of any changes in the law or
events that may hereafter come to our attention that could affect our opinion
set forth below.

         Based on the foregoing, we are of the opinion that, for federal income
tax purposes:

         1. The summaries of United States federal income tax consequences set
forth in the Proxy Statement/Prospectus under the headings "Synopsis -- Tax
Consequences of the Reorganization", "The Reorganization -- The Board's
Consideration" and "The Reorganization --Tax Aspects of the Reorganization" are
accurate in all material respects as to matters of law and legal conclusions.

         2. The transfer of Minnesota Series' assets in exchange for Tax-Exempt
Shares(1) and the assumption by Tax-Exempt of certain stated liabilities of
Minnesota Series followed by the distribution by Minnesota Series of Tax-Exempt
Shares to the Minnesota Series Shareholders in exchange for their Minnesota
Series shares pursuant to and in accordance with the terms of the Reorganization
Agreement will constitute a "reorganization" within the meaning of section
368(a)(1)(C) of the Code, and Minnesota Series and Tax-Exempt will each be a
"party to a reorganization" within the meaning of section 368(b) of the Code.

         3. No gain or loss will be recognized by Tax-Exempt upon receipt of the
assets of Minnesota Series solely in exchange for Tax-Exempt Shares and the
assumption by Tax-Exempt of the stated liabilities of Minnesota Series.

         4. No gain or loss will be recognized by Minnesota Series upon the
transfer of the assets of Minnesota Series to Tax-Exempt in exchange for
Tax-Exempt Shares and the assumption by Tax-Exempt of the stated liabilities or
upon the distribution of Tax-Exempt Shares to the Minnesota Series Shareholders
in exchange for their Minnesota Series shares.

- --------
(1)      Capitalized terms used herein without definition have the meanings
         ascribed to them in the Reorganization Agreement.
<PAGE>


         5. No gain or loss will be recognized by the Minnesota Series
Shareholders upon the exchange of the Minnesota Series shares for Tax-Exempt
Shares.

         6. The aggregate tax basis for the Tax-Exempt Shares received by each
Minnesota Series Shareholder pursuant to the Reorganization will be the same as
the aggregate tax basis of the Minnesota Series shares held by each such
Minnesota Series Shareholder immediately prior to the Reorganization.

         7. The holding period of the Tax-Exempt Shares to be received by each
Minnesota Series Shareholder will include the period during which the Minnesota
Series shares surrendered in exchange therefor were held (provided such
Minnesota Series shares are held as capital assets on the date of the
Reorganization).

         8. The tax basis of the assets of Minnesota Series acquired by
Tax-Exempt will be the same as the tax basis of such assets to Minnesota Series
immediately prior to the Reorganization.

         9. The holding period of the assets of Minnesota Series in the hands of
Tax-Exempt will include the period during which those assets were held by
Minnesota Series.

         This opinion is being provided to you solely in connection with the
filing of the Registration Statement for the Reorganization. This opinion may
not be relied upon by you for any other purpose or relied upon by or furnished
to any other person without our prior written consent.

         We hereby consent to the filing of this opinion as an exhibit to the
Proxy Statement/Prospectus and to all references to this firm under the headings
"Synopsis -- Tax Consequences of the Reorganization" and "The Reorganization --
Tax Aspects of the Reorganization" in the Proxy Statement/Prospectus.

                                                   /s/ Mayer, Brown & Platt
