PROSPECTUS SUMMARY
- -------------------------------------------------------------------------------
The The Fund is organized as a Trust, commonly known as a
Fund Massachusetts business trust, and is an open-end,
diversified management investment company investing
principally in investment grade, tax-exempt fixed-income
securities (see page 8).
- -------------------------------------------------------------------------------
Shares Offered Shares of beneficial interest with $0.01 par value (see
page 26). The Fund offers four Classes of shares, each
with a different combination of sales charges, ongoing
fees and other features (see pages 13-21).
- -------------------------------------------------------------------------------
Minimum The minimum initial investment for each Class is $1,000
Purchase ($100 if the account is opened through EasyInvest (Service
Mark)). Class D shares are only available to persons
investing $5 million or more and to certain other limited
categories of investors. For the purpose of meeting the
minimum $5 million investment for Class D shares, and
subject to the $1,000 minimum initial investment for each
Class of the Fund, an investor's existing holdings of
Class A shares and shares of funds for which Dean Witter
InterCapital Inc. serves as investment manager ("Dean
Witter Funds") that are sold with a front-end sales
charge, and concurrent investments in Class D shares of
the Fund and other Dean Witter Funds that are multiple
class funds, will be aggregated. The minimum subsequent
investment is $100 (see page 13).
- -------------------------------------------------------------------------------
Investment The investment objective of the Fund is to provide a high
Objective level of current income exempt from federal income tax,
consistent with the preservation of capital (see page 8).
- -------------------------------------------------------------------------------
Investment Dean Witter InterCapital Inc. ("InterCapital"), the
Manager Investment Manager of the Fund, and its wholly-owned
subsidiary, Dean Witter Services Company Inc., serve in
various investment management, advisory, management and
administrative capacities to 101 investment companies and
other portfolios with assets of approximately $113.6
billion at March 31, 1998 (see page 8).
- -------------------------------------------------------------------------------
Management The monthly fee is at an annual rate of 1/2 of 1% of
Fee average daily net assets, scaled down on assets over $500
million (see page 8).
- -------------------------------------------------------------------------------
Distributor and Dean Witter Distributors Inc. (the "Distributor"). The
Distribution Fund has adopted a distribution plan pursuant to Rule
Fee 12b-1 under the Investment Company Act (the "12b-1 Plan")
with respect to the distribution fees paid by the Class A,
Class B and Class C shares of the Fund to the Distributor.
The entire 12b-1 fee payable by Class A and a portion of
the 12b-1 fee payable by each of Class B and Class C 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 within the
meaning of the National Association of Securities Dealers,
Inc. guidelines. The remaining portion of the 12b-1 fee,
if any, is characterized as an asset-based sales charge
(see pages 13 and 20).
- -------------------------------------------------------------------------------
Alternative Four classes of shares are offered:
Purchase
Arrangements o Class A shares are offered with a front-end sales
charge, starting at 4.25% and reduced for larger
purchases. Investments of $1 million or more (and
investments by certain other limited categories of
investors) are not subject to any sales charge at the time
of purchase but a contingent deferred sales charge
("CDSC") of 1.0% may be imposed on redemptions within one
year of purchase. The Fund is authorized to reimburse the
Distributor for specific expenses incurred in promoting
the distribution of the Fund's Class A shares and
servicing shareholder accounts pursuant to the Fund's
12b-1 Plan. Reimbursement may in no event exceed an amount
equal to payments at an annual rate of 0.25% of average
daily net assets of the Class (see pages 13, 16 and 20).
o Class B shares are offered without a front-end sales
charge, but will in most cases be subject to a CDSC
(scaled down from 5.0% to 1.0%) if redeemed within six
years after purchase. The CDSC will be imposed on any
redemption of shares if after such redemption the
aggregate current value of a Class B account with the Fund
falls below the aggregate amount of the investor's
purchase payments made during the six years preceding the
redemption. Class B shares are also subject to a 12b-1 fee
assessed at the annual rate of 0.60% of the average daily
net assets of Class B. Class B shares convert to Class A
shares approximately ten years after the date of the
original purchase (see pages 13, 17 and 20).
- -------------------------------------------------------------------------------

<PAGE>
- -------------------------------------------------------------------------------
o Class C shares are offered without a front-end sales
charge, but will in most cases be subject to a CDSC of
1.0% if redeemed within one year after purchase. The Fund
is authorized to reimburse the Distributor for specific
expenses incurred in promoting the distribution of the
Fund's Class C shares and servicing shareholder accounts
pursuant to the Fund's 12b-1 Plan. Reimbursement may in no
event exceed an amount equal to payments at an annual rate
of 0.70% of average daily net assets of the Class (see
pages 13, 19 and 20).
o Class D shares are offered only to investors meeting an
initial investment minimum of $5 million and to certain
other limited categories of investors. Class D shares are
offered without a front-end sales charge or CDSC and are
not subject to any 12b-1 fee (see pages 13, 19 and 20).
All shares of the Fund held prior to July 28, 1997 have
been designated Class D shares. Additional investments in
Class D shares by shareholders holding such shares may
only be made if those shareholders are otherwise eligible
to purchase Class D shares. However, shareholders holding
such shares will receive the benefit of the value of such
shares towards reduced sales charges on purchases of Class
A shares pursuant to the Fund's "Right of Accumulation"
(see page 17).
- -------------------------------------------------------------------------------
Dividends and Dividends from net investment income are declared daily
Capital Gains and paid monthly; capital gains, if any, may be
Distributions distributed annually or retained for reinvestment by the
Fund. Dividends and capital gains distributions paid on
shares of a Class are automatically reinvested in
additional shares of the same Class at net asset value
unless the shareholder elects to receive cash. Shares
acquired by dividend and distribution reinvestment will
not be subject to any sales charge or CDSC (see pages 21
and 24).
- -------------------------------------------------------------------------------
Redemption Shares are redeemable by the shareholder at net asset
value less any applicable CDSC on Class A, Class B or
Class C shares. An account may be involuntarily redeemed
if the total value of the account is less than $100 or, if
the account was opened through EasyInvest (Service Mark),
if after twelve months the shareholder has invested less
than $1,000 in the account (see page 24).
- -------------------------------------------------------------------------------
Risks The value of the Fund's portfolio securities, and
therefore the Fund's net asset value per share, may
increase or decrease due to various factors, principally
changes in prevailing interest rates and the ability of
the issuers of the Fund's portfolio securities to pay
interest and principal on such obligations. The Fund may
purchase when-issued and delayed delivery securities (see
page 10). The Fund may also invest in futures and options,
which may be considered speculative in nature and which
may involve greater risks than those customarily assumed
by certain other investment companies which do not invest
in such instruments (see pages 10-12).
- -------------------------------------------------------------------------------
The above is qualified in its entirety by the detailed information appearing
elsewhere in the Prospectus and in the Statement of Additional Information.

(1) Reduced for purchases of $25,000 and over (see "Purchase of Fund
Shares--Initial Sales Charge Alternative--Class A Shares").
(2) Investments that are not subject to any sales charge at the time of
purchase are subject to a CDSC of 1.00% that will be imposed on
redemptions made within one year after purchase, except for certain
specific circumstances (see "Purchase of Fund Shares--Initial Sales
Charge Alternative--Class A Shares").
(3) The CDSC is scaled down to 1.00% during the sixth year, reaching zero
thereafter.
(4) Only applicable to redemptions made within one year after purchase (see
"Purchase of Fund Shares--Level Load Alternative--Class C Shares").
(5) The 12b-1 fee is accrued daily and payable monthly. The entire 12b-1
fee payable by Class A and a portion of the 12b-1 fee payable by each
of Class B and Class C 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 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. The remainder of the 12b-1 fee, if any, is an
asset-based sales charge, and is a distribution fee paid to the
Distributor to compensate it for the services provided and the expenses
borne by the Distributor and others in the distribution of the Fund's
shares (see "Purchase of Fund Shares--Plan of Distribution").
(6) Upon conversion of Class B shares to Class A shares, such shares will
be subject to the lower 12b-1 fee applicable to Class A shares. No
sales charge is imposed at the time of conversion of Class B shares to
Class A shares. Class C shares do not have a conversion feature and,
therefore, are subject to an ongoing 0.70% distribution fee (see
"Purchase of Fund Shares--Alternative Purchase Arrangements").
(7) There were no outstanding shares of Class A, Class B or Class C prior
to July 28, 1997. Accordingly, "Total Fund Operating Expenses," as
shown above with respect to those Classes, are estimates based upon the
sum of 12b-1 Fees, Management Fees and estimated "Other Expenses."

indirectly. For a more complete description of these costs and expenses, see
"The Fund and its Management," "Purchase of Fund Shares--Plan of
Distribution" and "Redemptions and Repurchases."

THE FUND AND ITS MANAGEMENT
- -------------------------------------------------------------------------------
Dean Witter Tax-Exempt Securities Trust (the "Fund") is an open-end,
diversified management investment company incorporated in Maryland on December
13, 1979. The Fund reorganized as a trust of the type commonly known as a
"Massachusetts business trust" on April 30, 1987.
Dean Witter InterCapital Inc. ("InterCapital" or the "Investment
Manager"), whose address is Two World Trade Center, New York, New York 10048,
is the Fund's Investment Manager. The Investment Manager, which was
incorporated in July, 1992, 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.
InterCapital and its wholly-owned subsidiary, Dean Witter Services Company
Inc., serve in various investment management, advisory, management and
administrative capacities to a total of 101 investment companies, 28 of which
are listed on the New York Stock Exchange, with combined total net assets of
approximately $109.5 billion as of March 31, 1998. The Investment Manager
also manages portfolios of pension plans, other institutions and individuals
which aggregated approximately $4.1 billion at such date.
The Fund has retained the Investment Manager to provide administrative
services, manage its business affairs and manage the investment of the Fund's
assets, including the placing of orders for the purchase and sale of
portfolio securities. InterCapital has retained Dean Witter Services Company
Inc. to perform the aforementioned administrative services for the Fund.
The Fund's Trustees review the various services provided by or under the
direction of the Investment Manager to ensure that the Fund's general
investment policies and programs are being properly carried out and that
administrative services are being provided to the Fund in a satisfactory
manner.
As full compensation for the services and facilities furnished to the Fund
and for expenses of the Fund assumed by the Investment Manager, the Fund pays
the Investment Manager monthly compensation calculated daily at an annual
rate of 0.50% of the daily net assets of the Fund up to $500 million, scaled
down at various asset levels to 0.325% on net assets over $1.25 billion. For
the fiscal year ended December 31, 1997, the Fund accrued total compensation
to the Investment Manager amounting to 0.44% of the Fund's average daily net
assets and the total expenses of Class D amounted to 0.49% of the Fund's
average daily net assets of Class D. Shares of Class A, Class B and Class C
were first issued on July 28, 1997. The expenses of the Fund include: the fee
of the Investment Manager; the fee pursuant to the Plan of Distribution (see
"Purchase of Fund Shares"); taxes; transfer agent, custodian and auditing
fees; certain legal fees; and printing and other expenses relating to the
Fund's operations which are not expressly assumed by the Investment Manager
under its Investment Management Agreement with the Fund.
INVESTMENT OBJECTIVE AND POLICIES
- -------------------------------------------------------------------------------
The investment objective of the Fund is to provide a high level of current
income which is exempt from federal income tax, consistent with the
preservation of capital. There is no assurance that this objective will be
achieved. This objective is fundamental and may not be changed without
shareholder approval. The Fund seeks to achieve its investment objective by
investing its assets in accordance with the following policies:
1. At least 80% of the Fund's total assets will be invested in tax-exempt
securities, except as stated in paragraph (5) below. Tax-exempt securities
consist of Municipal Bonds and Municipal Notes ("Municipal Obligations") and
Municipal Commercial Paper.
2. At least 75% of the Fund's total assets will be invested in: (a)
Municipal Bonds which are rated at the time of purchase within the three
highest grades by Moody's Investors Service, Inc. ("Moody's") or Standard &
Poor's Corporation ("S&P"); (b) Municipal Notes which at the time of purchase
are rated in the two highest grades by Moody's or S&P, or, if not rated, have
outstanding one or more issues of Municipal Bonds rated as set forth in
clause (a) of this paragraph; and (c) Municipal Commercial Paper which at the
time of purchase are rated P-1 by Moody's or A-1 by S&P.
3. Up to 25% of the Fund's total assets may be invested in tax-exempt
securities which are not rated by Moody's or S&P or, if rated, are not within
the rating categories of Moody's or S&P stated in paragraph (2) above.
4. In accordance with the current position of the staff of the Securities
and Exchange Commission, tax-exempt securities which are subject to the
federal alternative minimum tax for individual shareholders will not be
included in the 80% total described in paragraph 1
8
<PAGE>
above. (See "Dividends, Distributions and Taxes," below.) As such, the
remaining 20% of the Fund's total assets may be invested in tax-exempt
securities subject to the alternative minimum tax.
5. Inclusive of paragraph 4 above, up to 20% of the Fund's total assets
may be invested in taxable money market instruments under any one or more of
the following circumstances: (a) pending investment of proceeds of sale of
Fund 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. In addition, the Fund may temporarily invest
more than 20% of its total assets in taxable securities, or in tax-exempt
securities subject to the federal alternative minimum tax for individual
shareholders, to maintain a "defensive" posture when, in the opinion of the
Investment Manager, it is advisable to do so because of market conditions.
The types of taxable securities in which the Fund may temporarily 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 or A-1 by S&P; (iii) certificates of deposit of
domestic banks with assets of $1 billion or more; and (iv) repurchase
agreements with respect to any of the foregoing portfolio securities.
Municipal Obligations are debt obligations of states, cities,
municipalities and municipal agencies which generally have maturities, at the
time of their issuance, of either one year or more (Bonds) or from six months
to three years (Notes). Municipal Commercial Paper refers to short-term
obligations of municipalities. Any Municipal Obligation which depends
directly or indirectly on the credit of the Federal Government shall be
considered to have a rating of Aaa/AAA. The Fund may purchase Municipal
Obligations which had originally been issued by the same issuer as two
separate series of the same issue with different interest rates, but which
are now linked together to form one series.
While the Fund may invest up to 25% of its total assets in Municipal
Obligations which are unrated or, if rated, are not within the three highest
Bond rating categories of Moody's or S&P or the two highest Note rating
categories of Moody's or S&P, the Fund does not intend to invest in Municipal
Bonds which are rated below either Baa by Moody's or BBB by S&P (the lowest
ratings considered investment grade) or, if not rated, are deemed by the
Investment Manager to be below investment grade, in amounts exceeding 5% of
its total assets. Investments in Municipal Bonds rated either Baa by Moody's
or BBB by S&P may have speculative characteristics and, therefore, changes in
economic conditions or other circumstances are more likely to weaken their
capacity to make principal and interest payments than would be the case with
investments in securities with higher credit ratings. Municipal Bonds rated
below investment grade may not currently be paying any interest and may have
extremely poor prospects of ever attaining any real investment standing.
The two principal classifications of Municipal Obligations and Commercial
Paper are "general obligation" and "revenue" obligations or commercial paper.
General obligation bonds, notes or commercial paper are secured by the
issuer's pledge of its faith, credit and taxing power for the payment of
principal and interest. Issuers of general obligation bonds, notes or
commercial paper include a state, its counties, cities, towns and other state
government units. Revenue bonds, notes or commercial paper are payable from
the revenues derived from a particular facility or class of facilities or, in
some cases, from specific revenue sources. Revenue bonds, notes or commercial
paper are issued for a wide variety of purposes, including the financing of
electric, gas, water and sewer systems and other public utilities; industrial
development and pollution control facilities; single and multi-family housing
units; public buildings and facilities; air and marine ports; transportation
facilities such as toll roads, bridges and tunnels; and health and
educational facilities such as hospitals and dormitories. They rely primarily
on user fees to pay debt service, although the principal revenue source is
often supplemented by additional security features which are intended to
enhance the creditworthiness of the issuer's obligations. In some cases,
particularly revenue bonds issued to finance housing and public buildings, a
direct or implied "moral obligation" of a governmental unit may be pledged to
the payment of debt service. In other cases, a special tax or other charge
may augment user fees.
Included within the revenue category are participations in lease
obligations or installment purchase contracts (hereinafter collectively
called "lease obligations") of municipalities. State and local governments
issue lease obligations to acquire equipment and facilities.
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
9
<PAGE>
appropriated for such 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 such legislative actions do not occur, the
holders of the lease obligation may experience difficulty in exercising their
rights, including disposition of the property.
Lease obligations represent a type of financing that may not have the
depth of marketability associated with more conventional municipal
obligations, and, as a result, certain of such lease obligations may be
considered illiquid securities. To determine whether or not the Fund will
consider such securities to be illiquid (the Fund may not invest more than
ten percent of its net assets in illiquid securities), the Trustees of the
Fund have established guidelines to be utilized by the Fund in determining
the liquidity of a lease obligation. The factors to be considered in making
the determination include: 1) the frequency of trades and quoted prices for
the obligation; 2) the number of dealers willing to purchase or sell the
security and the number of other potential purchasers; 3) the willingness of
dealers to undertake to make a market in the security; and 4) the nature of
the marketplace trades, including, the time needed to dispose of the
security, the method of soliciting offers, and the mechanics of the transfer.
The interest rates payable on certain Municipal Bonds and Municipal Notes
are not fixed and may fluctuate based upon changes in market rates. Municipal
obligations of this type are called "variable rate" obligations. 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.
The foregoing percentage and rating policies apply at the time of
acquisition of a security based on the last previous determination of the
Fund's net asset value. Any subsequent change in any rating by a rating
service or change in percentages resulting from market fluctuations or other
changes in the Fund's total assets will not require elimination of any
security from the Fund's portfolio until such time as the Investment Manager
determines that it is practicable to sell the security without undue market
or tax consequences to the Fund.
The ratings assigned by Moody's and S&P represent their opinions as to the
quality of the securities which they undertake to rate (see the Appendix to
the Statement of Additional Information). It should be emphasized, however,
that the ratings are general and not absolute standards of quality.
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. The Fund may purchase tax-exempt
securities on a when-issued or delayed delivery basis; i.e., delivery and
payment can take place a month or more after the date of the transaction.
These securities are subject to market fluctuation and no interest accrues to
the purchaser prior to settlement. At the time the Fund makes the commitment
to purchase such securities, it will record the transaction and thereafter
reflect the value, each day, of such securities in determining its net asset
value. An increase in the percentage of the Fund's assets committed to the
purchase of securities on a when-issued or delayed delivery basis may
increase the volatility of the Fund's net asset value.
ZERO COUPON SECURITIES. A portion of the fixed-income securities purchased by
the Fund may be zero coupon securities. Such securities are purchased at a
discount from their face amount, giving the purchaser the right to receive
their full value at maturity. The interest earned on such securities is,
implicitly, automatically compounded and paid out at maturity. While such
compounding at a constant rate eliminates the risk of receiving lower yields
upon reinvestment of interest if prevailing interest rates decline, the owner
of a zero coupon security will be unable to participate in higher yields upon
reinvestment of interest received on interest-paying securities if prevailing
interest rates rise.
A zero coupon security pays no interest to its holder during its life.
Therefore, to the extent the Fund invests in zero coupon securities, it will
not receive current cash available for distribution to shareholders. In
addition, zero coupon securities are subject to substantially greater price
fluctuations during periods of changing prevailing interest rates than are
comparable securities which pay interest on a current basis. Current federal
tax law requires that a holder (such as the Fund) of a zero coupon security
accrue a portion of the discount at which the security was purchased as
income each year even though the Fund receives no interest payments in cash
on the security during the year.
RISK CONSIDERATIONS AND INVESTMENT PRACTICES
The value of the Fund's portfolio securities and, therefore, the Fund's net
asset value per share, may increase or decrease due to various factors,
principally changes in prevailing interest rates and the ability of the
issuers of the Fund's portfolio securities to pay interest and principal on
such obligations on a timely basis. Generally, a rise in interest rates will
result in a decrease in the Fund's net asset value per share, while a drop in
interest rates will result in an increase in the Fund's net asset value per
10
<PAGE>
share. The Fund's yield will also vary based on the yield of the Fund's
portfolio securities.
FUTURES CONTRACTS AND OPTIONS ON FUTURES. The Fund may enter into financial
futures contracts ("futures contracts"), options on such futures and
municipal bond index futures contracts for hedging purposes. The Fund may
sell a futures contract or a call option thereon or purchase a put option on
such futures contract, if the Investment Manager anticipates interest rates
to rise, as a hedge against a decrease in the value of the Fund's portfolio
securities. If the Investment Manager anticipates that interest rates will
decline, the Fund may purchase a futures contract or a call option thereon or
sell a put option on such futures contract, to protect against an increase in
the price of the securities the Fund intends to purchase. 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 creates 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 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 effected by entering into an offsetting
purchase or sale transaction.
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 option on the contract is lost. Since the value of the
option is fixed at the point of sale, there are not daily payments of cash to
reflect the change in the value of the underlying contract as there are by a
purchaser or seller of a futures contract. The value of the option does
change and is reflected in the net asset value of the Fund.
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 the Fund's portfolio securities. The risk of imperfect correlation
may be increased by the fact that the Fund will invest in futures contracts
on taxable securities and there is no guarantee that the prices of taxable
securities will move in a similar manner to the prices of tax-exempt
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. Such distortions are generally minor and would diminish as
the contract approached maturity.
Another risk is that the Fund's 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 then interest rates went down instead,
causing bond prices to rise, the Fund would lose money on the sale.
In addition to the risks that apply to all options transactions (see the
Statement of Additional Information for a description of the characteristics
of, and the risks of investing in, options on debt securities), there are
several special risks relating to options on futures; in particular, the
ability to establish and close out positions on options on futures will be
subject to the development and maintenance of a liquid secondary market. It
is not certain that this market will develop or be maintained.
MUNICIPAL BOND INDEX FUTURES. The Fund may utilize municipal bond index
futures contracts and options thereon for hedging purposes. The Fund's
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 purchase or sale of an offsetting
contract for the same delivery month prior to expiration of the contract.
The Fund may not enter into futures contracts or purchase related options
thereon if immediately thereafter the amount committed to margin plus the
amount paid for premiums for unexpired options on futures contracts exceeds
5% of the value of the Fund's total assets. The Fund may not purchase or sell
futures
11
<PAGE>
contracts or related options thereon if, immediately thereafter, more than
one-third of its net assets would be hedged.
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 cannot
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. The Investment Manager, the Distributor and the Transfer Agent have
been actively working on necessary changes to their own computer systems to
prepare for the year 2000 and expect that their systems will be adapted
before that date, but there can be no assurance that they will be successful,
or that interaction with other non-complying computer systems will not impair
their services at that time.
In addition, it is possible that the markets for securities in which the
Fund invests may be detrimentally affected by computer failures throughout
the financial services industry beginning January 1, 2000. Improperly
functioning trading systems may result in settlement problems and liquidity
issues. In addition, corporate and governmental data processing errors may
result in production problems for individual companies and overall economic
uncertainties. Earnings of individual issuers will be affected by remediation
costs, which may be substantial. Accordingly, the Fund's investments may be
adversely affected.
For a discussion of the risks of certain types of Municipal Obligations,
such as lease obligations, see above in "Investment Objective and Policies."
PORTFOLIO MANAGEMENT
The Fund is actively managed by the Investment Manager with a view to
achieving the Fund's investment objective. In determining which securities to
purchase for the Fund or hold in the Fund's portfolio, the Investment Manager
will rely on information from various sources, including research, analysis
and appraisals of brokers and dealers, including Dean Witter Reynolds Inc.
("DWR"), Morgan Stanley & Co. Incorporated and other broker-dealer affiliates
of InterCapital, the views of others regarding economic developments and
interest rate trends, and the Investment Manager's own analysis of factors it
deems relevant. The Fund is managed within InterCapital's Tax-Exempt Group,
which manages 39 tax-exempt municipal funds and fund portfolios, with
approximately $11.2 billion in assets as of March 31, 1998. James F.
Willison, Senior Vice President of InterCapital and Manager of InterCapital's
Municipal Fixed Income Group and Joseph R. Arcieri, Vice President of
InterCapital and a member of InterCapital's Municipal Fixed Income Group,
have been the primary portfolio co-managers of the Fund since its inception
and February, 1997, respectively, and have been portfolio managers at
InterCapital for over five years.
Securities are purchased and sold principally in response to the
Investment Manager's current evaluation of an issuer's ability to meet its
debt obligations in the future, and the Investment Manager's current
assessment of future changes in the levels of interest rates on tax-exempt
securities of varying maturities. Securities purchased by the Fund are,
generally, sold by dealers acting as principal for their own accounts.
Pursuant to an order of the Securities and Exchange Commission, the Fund may
effect principal transactions in certain money market instruments with DWR.
In addition, the Fund may incur brokerage commissions on transactions
conducted through DWR, Morgan Stanley & Co. Incorporated and other brokers
and dealers that are affiliates of InterCapital.
The portfolio trading engaged in by the Fund may result in its portfolio
turnover rate exceeding 100%. A portfolio turnover rate in excess of 100% may
be considered high and the Fund will incur correspondingly higher transaction
costs. Additionally, see "Dividends, Distributions and Taxes" for a
discussion of the tax policy of the Fund. A more extensive discussion of the
Fund's portfolio brokerage policies is set forth in the Statement of
Additional Information.
Except as specifically noted, all investment objectives, policies and
practices discussed above are not fundamental policies of the Fund and, as
such, may be changed without shareholder approval.
INVESTMENT RESTRICTIONS
- -------------------------------------------------------------------------------
The investment restrictions listed below are among the restrictions which
have been adopted by the Fund as fundamental policies. Under the Investment
Company Act of 1940, as amended (the "Act"), a fundamental policy may not be
changed without the vote of a majority of the outstanding voting securities
of the Fund, as defined in the Act.
12
<PAGE>
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 to be a security
issued by the guarantor if the value of all securities issued or 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 the Fund's total assets does not require
elimination of any security from the portfolio.
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 or
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 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 cash equivalents (industrial development and
pollution control bonds are grouped into industries based upon the business
in which the issuers of such obligations are engaged).
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 obligation of the United States Government, its agencies or
instrumentalities.
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.
PURCHASE OF FUND SHARES
- -------------------------------------------------------------------------------
GENERAL
The Fund offers each class of its shares for sale to the public on a
continuous basis. Pursuant to a Distribution Agreement between the Fund and
Dean Witter Distributors Inc. (the "Distributor"), an affiliate of the
Investment Manager, shares of the Fund are distributed by the Distributor and
offered by DWR and other dealers who have entered into agreements with the
Distributor ("Selected Broker-Dealers"). The principal executive office of
the Distributor is located at Two World Trade Center, New York, New York
10048.
The Fund offers four classes of shares (each, a "Class"). Class A shares
are sold to investors with an initial sales charge that declines to zero for
larger purchases; however, Class A shares sold without an initial sales
charge are subject to a contingent deferred sales charge ("CDSC") of 1.0% if
redeemed within one year of purchase, except for certain specific
circumstances. Class B shares are sold without an initial sales charge but
are subject to a CDSC (scaled down from 5.0% to 1.0%) payable upon most
redemptions within six years after purchase. Class C shares are sold without
an initial sales charge but are subject to a CDSC of 1.0% on most redemptions
made within one year after purchase. Class D shares are sold without an
initial sales charge or CDSC and are available only to investors meeting an
initial investment minimum of $5 million, and to certain other limited
categories of investors. At the discretion of the Board of Trustees of the
Fund, Class A shares may be sold to categories of investors in addition to
those set forth in this prospectus at net asset value without a front-end
sales charge, and Class D shares may be sold to certain other categories of
investors, in each case as may be described in the then current prospectus of
the Fund. See "Alternative Purchase Arrangements--Selecting a Particular
Class" for a discussion of factors to consider in selecting which Class of
shares to purchase.
The minimum initial purchase is $1,000 for each Class of shares, although
Class D shares are only available to persons investing $5 million or more and
to certain other limited categories of investors. For the purpose of meeting
the minimum $5 million initial investment for Class D shares, and subject to
the $1,000 minimum initial investment for each Class of the Fund, an
investor's existing holdings of Class A shares of the Fund
13
<PAGE>
and other Dean Witter Funds that are multiple class funds ("Dean Witter
Multi-Class Funds") and shares of Dean Witter Funds sold with a front-end
sales charge ("FSC Funds") and concurrent investments in Class D shares of
the Fund and other Dean Witter Multi-Class Funds will be aggregated.
Subsequent purchases of $100 or more may be made by sending a check, payable
to Dean Witter Tax-Exempt Securities Trust, directly to Morgan Stanley Dean
Witter Trust FSB (the "Transfer Agent" or "MSDW Trust") at P.O. Box 1040,
Jersey City, N.J. 07303 or by contacting an account executive of DWR or other
Selected Broker-Dealer. When purchasing shares of the Fund, investors must
specify whether the purchase is for Class A, Class B, Class C or Class D
shares. If no Class is specified, the Transfer Agent will not process the
transaction until the proper Class is identified. The minimum initial
purchase in the case of investments through EasyInvest (Service Mark), an
automatic purchase plan (see "Shareholder Services"), is $100, provided that
the schedule of automatic investments will result in investments totalling at
least $1,000 within the first twelve months. In the case of purchases made
pursuant to (i) systematic payroll deduction plans, (ii) the InterCapital
mutual fund asset allocation program and (iii) fee-based programs approved by
the Distributor, pursuant to which participants pay an asset based fee for
services in the nature of investment advisory, administrative and/or
brokerage services, the Fund, in its discretion, may accept such purchases
without regard to any minimum amounts which would otherwise be required,
provided, in the case of systematic payroll deduction plans, that the
Distributor has reason to believe that additional purchases will increase the
amount of the purchase of shares in all accounts under such plans to at least
$1,000. Certificates for shares purchased will not be issued unless a request
is made by the shareholder in writing to the Transfer Agent.
Shares of the Fund are sold through the Distributor on a normal three
business day settlement basis; that is, payment generally is due on or before
the third business day (settlement date) after the order is placed with the
Distributor. Shares of the Fund purchased through the Distributor are
entitled to dividends beginning on the next business day following settlement
date. Since DWR and other Selected Broker-Dealers forward investors' funds on
settlement date, they will benefit from the temporary use of the funds where
payment is made prior thereto. Shares purchased through the Transfer Agent
are entitled to dividends beginning on the next business day following
receipt of an order. As noted above, orders placed directly with the Transfer
Agent must be accompanied by payment. Investors will be entitled to receive
capital gains distributions if their order is received by the close of
business on the day prior to the record date for such distributions. Sales
personnel of a Selected Broker-Dealer are compensated for selling shares of
the Fund by the Distributor or any of its affiliates and/or the Selected
Broker-Dealer. In addition, some sales personnel of the Selected
Broker-Dealer will receive various types of non-cash compensation as special
sales incentives, including trips, educational and/or business seminars and
merchandise. The Fund and/or the Distributor reserve the right to reject any
purchase order.
ALTERNATIVE PURCHASE ARRANGEMENTS
The Fund offers several Classes of shares to investors designed to provide
them with the flexibility of selecting an investment best suited to their
needs. The general public is offered three Classes of shares: Class A shares,
Class B shares and Class C shares, which differ principally in terms of sales
charges and rate of expenses to which they are subject. A fourth Class of
shares, Class D shares, is offered only to limited categories of investors
(see "No Load Alternative--Class D Shares" below).
Each Class A, Class B, Class C or Class D share of the Fund represents an
identical interest in the investment portfolio of the Fund except that Class
A, Class B and Class C shares bear the expenses of the ongoing shareholder
service fees, Class B and Class C shares bear the expenses of the ongoing
distribution fees and Class A, Class B and Class C shares which are redeemed
subject to a CDSC bear the expense of the additional incremental distribution
costs resulting from the CDSC applicable to shares of those Classes. The
ongoing distribution fees that are imposed on Class A, Class B and Class C
shares will be imposed directly against those Classes and not against all
assets of the Fund and, accordingly, such charges against one Class will not
affect the net asset value of any other Class or have any impact on investors
choosing another sales charge option. See "Plan of Distribution" and
"Redemptions and Repurchases."
Set forth below is a summary of the differences between the Classes and
the factors an investor should consider when selecting a particular Class.
This summary is qualified in its entirety by detailed discussion of each
Class that follows this summary.
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 certain
purchases. Investments of $1 million or more (and investments by certain
other limited categories of investors) are not subject to any sales charges
at the time of purchase but are subject to a CDSC of 1.0% on redemptions made
within one year after purchase, except for certain specific circumstances.
Class A shares are also subject to a 12b-1
14
<PAGE>
fee of up to 0.25% of the average daily net assets of the Class. See "Initial
Sales Charge Alternative--Class A Shares."
CLASS B SHARES. Class B shares are offered at net asset value with no initial
sales charge but are subject to a CDSC (scaled down from 5.0% to 1.0%) if
redeemed within six years of purchase. This CDSC may be waived for certain
redemptions. Class B shares are also subject to an annual 12b-1 fee of 0.60%
of the average daily net assets of Class B. The Class B shares' distribution
fee will cause that Class to have higher expenses and pay lower dividends
than Class A or Class D shares.
After approximately ten (10) years, Class B shares will convert
automatically to Class A shares of the Fund, based on the relative net asset
values of the shares of the two Classes on the conversion date. In addition,
a certain portion of Class B shares that have been acquired through the
reinvestment of dividends and distributions will be converted at that time.
See "Contingent Deferred Sales Charge Alternative--Class B Shares."
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 redemptions made within one
year after purchase. This CDSC may be waived for certain redemptions. They
are subject to an annual 12b-1 fee of up to 0.70% of the average daily net
assets of the Class C shares. 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. See "Level Load Alternative--Class C Shares."
CLASS D SHARES. Class D shares are available only to limited categories of
investors (see "No Load Alternative--Class D Shares" below). Class D shares
are sold at net asset value with no initial sales charge or CDSC. They are
not subject to any 12b-1 fees. See "No Load Alternative--Class D Shares."
SELECTING A PARTICULAR CLASS. In deciding which Class of Fund shares to
purchase, investors should consider the following factors, as well as any
other relevant facts and circumstances:
The decision as to which Class of shares is more beneficial to an investor
depends on the amount and intended length of his or her investment. Investors
who prefer an initial sales charge alternative may elect to purchase Class A
shares. Investors qualifying for signifi-cantly reduced or, in the case of
purchases of $1 million or more, no initial sales charges may find Class A
shares particularly attractive because similar sales charge reductions are
not available with respect to Class B or Class C shares. Moreover, Class A
shares are subject to lower ongoing expenses than are Class B or Class C
shares over the term of the investment. As an alternative, Class B and Class
C shares are sold without any initial sales charge so the entire purchase
price is immediately invested in the Fund. Any investment return on these
additional investment amounts may partially or wholly offset the higher
annual expenses of these Classes. Because the Fund's future return cannot be
predicted, however, there can be no assurance that this would be the case.
Finally, investors should consider the effect of the CDSC period and any
conversion rights of the Classes in the context of their own investment time
frame. For example, although Class C shares are subject to a significantly
lower CDSC upon redemptions, they do not, unlike Class B shares, convert into
Class A shares after approximately ten years, and, therefore, are subject to
an ongoing 12b-1 fee of 0.70% (rather than the 0.25% fee applicable to Class
A shares) for an indefinite period of time. Thus, Class B shares may be more
attractive than Class C shares to investors with longer term investment
outlooks. Other investors, however, may elect to purchase Class C shares if,
for example, they determine that they do not wish to be subject to a
front-end sales charge and they are uncertain as to the length of time they
intend to hold their shares.
For the purpose of meeting the $5 million minimum investment amount for
Class D shares, holdings of Class A shares in all Dean Witter Multi-Class
Funds, shares of FSC Funds and shares of Dean Witter Funds for which such
shares have been exchanged will be included together with the current
investment amount.
Sales personnel may receive different compensation for selling each Class
of shares. Investors should understand that the purpose of a CDSC is the same
as that of the initial sales charge in that the sales charges applicable to
each Class provide for the financing of the distribution of shares of that
Class.

See "Purchase of Fund Shares" and "The Fund and its Management" for a
complete description of the sales charges and service and distribution fees
for each Class of shares and "Determination of Net Asset Value," "Dividends,
Distributions and Taxes" and "Shareholder Services--Exchange Privilege" for
other differences between the Classes of shares.
INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES
Class A shares are sold at net asset value plus an initial sales charge. In
some cases, reduced sales charges may be available, as described below.
Investments of $1 million or more (and investments by certain other limited
categories of investors) are not subject to any sales charges at the time of
purchase but are subject to a CDSC of 1.0% on redemptions made within one
year after purchase (calculated from the last day of the month in which the
shares were purchased), except for certain specific circumstances. The CDSC
will be assessed on an amount equal to the lesser of the current market value
or the cost of the shares being redeemed. The CDSC will not be imposed (i) in
the circumstances set forth below in the section "Contingent Deferred Sales
Charge Alternative--Class B Shares--CDSC Waivers," except that the references
to six years in the first paragraph of that section shall mean one year in
the case of Class A shares, and (ii) in the circumstances identified in the
section "Additional Net Asset Value Purchase Options" below. Class A shares
are also subject to an annual 12b-1 fee of up to 0.25% of the average daily
net assets of the Class.
The offering price of Class A shares will be the net asset value per share
next determined following receipt of an order (see "Determination of Net
Asset Value" below), plus a sales charge (expressed as a percentage of the
offering price) on a single transaction as shown in the following table:

Upon notice to all Selected Broker-Dealers, the Distributor may reallow up
to the full applicable sales charge as shown in the above schedule 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 of 1933.
The above schedule of sales charges is applicable to purchases in a single
transaction by, among others: (a) an individual; (b) an individual, his or
her spouse and their children under the age of 21 purchasing shares for his,
her or their own accounts; (c) a trustee or other fiduciary purchasing shares
for a single trust estate or a single fiduciary account; (d) a pension,
profit-sharing or other employee benefit plan qualified or non-qualified
under Section 401 of the Internal Revenue Code; (e) tax-exempt organizations
enumerated in Section 501(c)(3) or (13) of the Internal Revenue Code; (f)
employee benefit plans qualified under Section 401 of the Internal Revenue
Code of a single employer or of employers who are "affiliated persons" of
each other within the meaning of Section 2(a)(3)(c) of the Act; and for
investments in Individual Retirement Accounts of employees of a single
employer through Systematic Payroll Deduction plans; or (g) any other
organized group of persons, whether incorporated or not, provided the
organization has been in existence for at least six months and has some
purpose other than the purchase of redeemable securities of a registered
investment company at a discount.
COMBINED PURCHASE PRIVILEGE. Investors may have the benefit of reduced sales
charges in accordance with the above schedule by combining purchases of Class
A shares of the Fund in single transactions with the purchase of Class A
shares of other Dean Witter Multi-Class Funds and shares of FSC Funds. The
sales charge
16
<PAGE>
payable on the purchase of the Class A shares of the Fund, the Class A shares
of the other Dean Witter Multi-Class Funds and the shares of the FSC Funds
will be at their respective rates applicable to the total amount of the
combined concurrent purchases of such shares.
RIGHT OF ACCUMULATION. The above persons and entities may benefit from a
reduction of the sales charges in accordance with the above schedule if the
cumulative net asset value of Class A shares purchased in a single
transaction, together with shares of the Fund and other Dean Witter Funds
previously purchased at a price including a front-end sales charge (including
shares of the Fund and other Dean Witter Funds acquired in exchange for those
shares, and including in each case shares acquired through reinvestment of
dividends and distributions), which are held at the time of such transaction,
amounts to $25,000 or more. If such investor has a cumulative net asset value
of shares of FSC Funds and Class A and Class D shares that, together with the
current investment amount, is equal to at least $5 million, such investor is
eligible to purchase Class D shares subject to the $1,000 minimum initial
investment requirement of that Class of the Fund. See "No Load
Alternative--Class D Shares" below.
The Distributor must be notified by DWR or a Selected Broker-Dealer or the
shareholder 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 by the dealer or shareholder when such
an order is placed by mail. The reduced sales charge will not be granted if:
(a) such notification is not furnished at the time of the order; or (b) a
review of the records of the Selected Broker-Dealer or the Transfer Agent
fails to confirm the investor's represented holdings.
LETTER OF INTENT. The foregoing schedule of reduced sales charges will also
be available to investors who enter into a written Letter of Intent providing
for the purchase, within a thirteen-month period, of Class A shares of the
Fund from DWR or other Selected Broker-Dealers. The cost of Class A shares of
the Fund or shares of other Dean Witter Funds which were previously purchased
at a price including a front-end sales charge during the 90-day period prior
to the date of receipt by the Distributor of the Letter of Intent, or of
Class A shares of the Fund or shares of other Dean Witter Funds acquired in
exchange for shares of such funds purchased during such period at a price
including a front-end sales charge, which are still owned by the shareholder,
may also be included in determining the applicable reduction.
ADDITIONAL NET ASSET VALUE PURCHASE OPTIONS. In addition to investments of $1
million or more, Class A shares also may be purchased at net asset value by
the following:
(1) trusts for which MSDW Trust (an affiliate of the Investment Manager)
provides discretionary trustee services;
(2) persons participating in a fee-based program approved by the
Distributor, pursuant to which such persons pay an asset based fee for
services in the nature of investment advisory, administrative and/or
brokerage services (such investments are subject to all of the terms and
conditions of such programs, which may include termination fees, mandatory
redemption upon termination and such other circumstances as specified in the
programs' agreements and restrictions on transferability of Fund shares);
(3) investors who are clients of a Dean Witter account executive who
joined Dean Witter from another investment firm within six months prior to
the date of purchase of Fund shares by such investors, if the shares are
being purchased with the proceeds from a redemption of shares of an open-end
proprietary mutual fund of the account executive's previous firm which
imposed either a front-end or deferred sales charge, provided such purchase
was made within sixty days after the redemption and the proceeds of the
redemption had been maintained in the interim in cash or a money market fund;
and
(4) other categories of investors, at the discretion of the Board, as
disclosed in the then current prospectus of the Fund.
No CDSC will be imposed on redemptions of shares purchased pursuant to
paragraphs (1), (2) or (3), above.
For further information concerning purchases of the Fund's shares, contact
DWR or another Selected Broker-Dealer or consult the Statement of Additional
Information.
CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE--CLASS B SHARES
Class B shares are sold at net asset value next determined without an initial
sales charge so that the full amount of an investor's purchase payment may be
immediately invested in the Fund. A CDSC, however, will be imposed on most
Class B shares redeemed within six years after purchase. The CDSC will be
imposed on any redemption of shares if after such redemption the aggregate
current value of a Class B account with the Fund falls below the aggregate
amount of the investor's purchase payments for Class B shares made during the
six years preceding the redemption. In addition, Class B shares are subject
to an annual 12b-1 fee of 0.60% of the average daily net assets of Class B.
17
<PAGE>
Except as noted below, Class B shares of the Fund which are held for six
years or more after purchase (calculated from the last day of the month in
which the shares were purchased) will not be subject to any CDSC upon
redemption. Shares redeemed earlier than six years after purchase may,
however, be subject to a CDSC which will be a percentage of the dollar amount
of shares redeemed and will be assessed on an amount equal to the lesser of
the current market value or the cost of the shares being redeemed. The size
of this percentage will depend upon how long the shares have been held, as
set forth in the following table:
<TABLE>

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 for shares of a fund with a
higher CDSC schedule or (ii) having been exchanged for shares of Dean Witter
Global Short-Term Income Fund Inc. ("Global Short-Term") or an Exchange Fund
(as defined below in "Shareholder Services--Exchange Privilege") 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 Global Short-Term or 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>
CDSC WAIVERS. A CDSC will not be imposed on: (i) any amount which represents
an increase in value of shares purchased within the six years preceding the
redemption; (ii) the current net asset value of shares purchased more than
six years prior to the redemption; and (iii) the current net asset value of
shares purchased through reinvestment of dividends or distributions and/or
shares acquired in exchange for shares of FSC Funds or of other Dean Witter
Funds acquired in exchange for such shares. Moreover, in determining whether
a CDSC is applicable it will be assumed that amounts described in (i), (ii)
and (iii) above (in that order) are redeemed first.
In addition, the CDSC, if otherwise applicable, will be waived in the case
of:
(1) redemptions of shares held at the time a shareholder dies or becomes
disabled, only if the shares are: (A) registered either in the name of an
individual shareholder (not a trust), or in the names of such shareholder and
his or her spouse as joint tenants with right of survivorship; or (B) held
in a qualified corporate or self-employed retirement plan, Individual
Retirement Account ("IRA") or Custodial Account under Section 403(b)(7) of
the Internal Revenue Code ("403(b) Custodial Account"), provided in either
case that the redemption is requested within one year of the death or initial
determination of disability; and
(2) redemptions in connection with the following retirement plan
distributions: (A) lump-sum or other distributions from a qualified
corporate or self-employed retirement plan following retirement (or, in the
case of a "key employee" of a "top heavy" plan, following attainment of age
59 1/2); (B) distributions from an IRA or 403(b) Custodial Account following
attainment of age 59 1/2; or (C) a tax-free return of an excess contribution
to an IRA.
With reference to (1) above, for the purpose of determining disability,
the Distributor utilizes the definition of disability contained in Section
72(m)(7) of the Internal Revenue Code, which relates to the inability to
engage in gainful employment. With reference to (2) above, the term
"distribution" does not encompass a direct transfer of IRA, 403(b) Custodial
Account or retirement plan assets to a successor custodian or trustee. All
waivers will be granted only following receipt by the Distributor of
confirmation of the shareholder's entitlement.

<PAGE>
CONVERSION TO CLASS A SHARES. Class B shares will convert automatically to
Class A shares, based on the relative net asset values of the shares of the
two Classes on the conversion date, which will be approximately ten (10)
years after the date of the original purchase. The ten year period is
calculated 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 or a series of
exchanges, from the last day of the month in which the original Class B
shares were purchased. The conversion of shares will take place in the month
following the tenth anniversary of the purchase. There will also be converted
at that time such proportion of Class B shares acquired through automatic
reinvestment of dividends and distributions owned by the shareholder as the
total number of his or her Class B shares converting at the time bears to the
total number of outstanding Class B shares purchased and owned by the
shareholder. In the case of Class B shares previously exchanged for shares of
an "Exchange Fund" (see "Shareholder Services--Exchange Privilege"), the
period of time the shares were held in the Exchange Fund (calculated from the
last day of the month in which the Exchange Fund shares were acquired) is
excluded from the holding period for conversion. If those shares are
subsequently re-exchanged for Class B shares of a Dean Witter Multi-Class
Fund, the holding period resumes on the last day of the month in which Class
B shares are reacquired.
If a shareholder has received share certificates for Class B shares, such
certificates must be delivered to the Transfer Agent at least one week prior
to the date for conversion. Class B shares evidenced by share certificates
that are not received by the Transfer Agent at least one week prior to any
conversion date will be converted into Class A shares on the next scheduled
conversion date after such certificates are received.
Effectiveness of the conversion feature is subject to the continuing
availability of a ruling of the Internal Revenue Service or an opinion of
counsel that (i) the conversion of shares does not constitute a taxable event
under the Internal Revenue Code, (ii) Class A shares received on conversion
will have a basis equal to the shareholder's basis in the converted Class B
shares immediately prior to the conversion, and (iii) Class A shares received
on conversion will have a holding period that includes the holding period of
the converted Class B shares. The conversion feature may be suspended if the
ruling or opinion is no longer available. In such event, Class B shares would
continue to be subject to Class B 12b-1 fees.
LEVEL LOAD ALTERNATIVE--CLASS C SHARES
Class C shares are sold at net asset value next determined without an initial
sales charge but are subject to a CDSC of 1.0% on most redemptions made
within one year after purchase (calculated from the last day of the month in
which the shares were purchased). The CDSC will be assessed on an amount
equal to the lesser of the current market value or the cost of the shares
being redeemed. The CDSC will not be imposed in the circumstances set forth
above in the section "Contingent Deferred Sales Charge Alternative--Class B
Shares--CDSC Waivers," except that the references to six years in the first
paragraph of that section shall mean one year in the case of Class C shares.
Class C shares are subject to an annual 12b-1 fee of up to 0.70% of the
average daily net assets of the Class. Unlike Class B shares, Class C shares
have no conversion feature and, accordingly, an investor that purchases Class
C shares will be subject to 12b-1 fees applicable to Class C shares for an
indefinite period subject to annual approval by the Fund's Board of Trustees
and regulatory limitations.
NO LOAD ALTERNATIVE--CLASS D SHARES
Class D shares are offered without any sales charge on purchase or redemption
and without any 12b-1 fee. Class D shares are offered only to investors
meeting an initial investment minimum of $5 million and the following
categories of investors: (i) investors participating in the InterCapital
mutual fund asset allocation program pursuant to which such persons pay an
asset based fee; (ii) persons participating in a fee-based program approved
by the Distributor, pursuant to which such persons pay an asset based fee for
services in the nature of investment advisory, administrative and/or
brokerage services (subject to all of the terms and conditions of such
programs referred to in (i) and (ii) above, which may include termination
fees mandatory redemption upon termination and such other circumstances as
specified in the programs' agreements, and restrictions on transferability of
Fund shares); (iii) certain Unit Investment Trusts sponsored by DWR; (iv)
certain other open-end investment companies whose shares are distributed by
the Distributor; and (v) other categories of investors, at the discretion of
the Board, as disclosed in the then current prospectus of the Fund. All
shares of the Fund held prior to July 28, 1997 have been designated Class D
shares. Additional investments in Class D shares by shareholders holding such
shares may only be made if those shareholders are otherwise eligible to
purchase Class D shares. However, shareholders holding such shares will
receive the benefit of the value of such shares towards reduced sales charges
on purchases of Class A shares pursuant to the Fund's "Right of Accumulation"
(see "Initial Sales Charge Alternative--Class A Shares--Right of
Accumulation"). Investors who require a $5 million minimum initial investment
to qualify to purchase Class
19
<PAGE>
D shares may satisfy that requirement by investing that amount in a single
transaction in Class D shares of the Fund and other Dean Witter Multi-Class
Funds, subject to the $1,000 minimum initial investment required for that
Class of the Fund. In addition, for the purpose of meeting the $5 million
minimum investment amount, holdings of Class A shares in all Dean Witter
Multi-Class Funds, shares of FSC Funds and shares of Dean Witter Funds for
which such shares have been exchanged will be included together with the
current investment amount. If a shareholder redeems Class A shares and
purchases Class D shares, such redemption may be a taxable event.
PLAN OF DISTRIBUTION
Effective July 28, 1997, the Fund has adopted a Plan of Distribution pursuant
to Rule 12b-1 under the Act with respect to the distribution of Class A,
Class B and Class C shares of the Fund. In the case of Class A and Class C
shares, the Plan provides that the Fund will reimburse the Distributor and
others for the expenses of certain activities and services incurred by them
specifically on behalf of those shares. Reimbursements for these expenses
will be made in monthly payments by the Fund to the Distributor, which will
in no event exceed amounts equal to payments at the annual rates of 0.25% and
0.70% of the average daily net assets of Class A and Class C, respectively.
In the case of Class B shares, the Plan provides that the Fund will pay the
Distributor a fee, which is accrued daily and paid monthly, at the annual
rate of 0.60% of the average daily net assets of Class B. The fee is treated
by the Fund as an expense in the year it is accrued. In the case of Class A
shares, the entire amount of the fee currently represents a service fee
within the meaning of the NASD guidelines. In the case of Class B and Class C
shares, a portion of the fee payable pursuant to the Plan, equal to 0.15% and
0.25% of the average daily net assets of each of these Classes, respectively,
is currently characterized as a service fee. A service fee is a payment made
for personal service and/or the maintenance of shareholder accounts.
Additional amounts paid under the Plan in the case of Class B and Class C
shares are paid to the Distributor for services provided and the expenses
borne by the Distributor and others in the distribution of the shares of
those Classes, including the payment of commissions for sales of the shares
of those Classes and incentive compensation to and expenses of DWR's account
executives and others who engage in or support distribution of shares or who
service shareholder accounts, including overhead and telephone expenses;
printing and distribution of prospectuses and reports used in connection with
the offering of the Fund's shares to other than current shareholders; and
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 DWR 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. For the fiscal period July 28 through December 31, 1997, Class A,
Class B and Class C shares of the Fund accrued payments under the Plan
amounting to $2,466, $83,261 and $4,834, which amounts on an annualized basis
are equal to 0.25%, 0.60% and 0.70% of the average daily net assets of Class
A, Class B and Class C, respectively, for such period.
In the case of Class B shares, at any given time, the expenses in
distributing Class B shares of the Fund may be in excess of the total of (i)
the payments made by the Fund pursuant to the Plan, and (ii) the proceeds of
CDSCs paid by investors upon the redemption of Class B 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 such excess amounts, including the carrying charge described above,
totalled $2,732,178 at December 31, 1997, which was equal to 2.86% of the net
assets of Class B on such date. Of this amount, $2,455,436 represents excess
distribution expenses of National Municipal, the net assets of which were
combined with those of the Fund on November 7, 1997 pursuant to the
Reorganization. Because there is no requirement under the Plan that the
Distributor be reimbursed for all distribution expenses or any requirement
that the Plan be continued from year to year, such 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 account executives at the
time of sale may be reimbursed in the subsequent calendar year. The
Distributor has advised the Fund that unreimbursed expenses representing a
gross sales commission credited
20
<PAGE>
to account executives at the time of sale totalled $22,030 in the case of
Class C at December 31, 1997, which amount was equal to 0.75% of the net
assets of Class C on such date, and that there were no such expenses that may
be reimbursed in the subsequent year in the case of Class A on such date. 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.
DETERMINATION OF NET ASSET VALUE
The net asset value per share is determined once daily at 4:00 p.m., New York
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),
by taking the net assets of the Fund, dividing by the number of shares
outstanding and adjusting to the nearest cent. The assets belonging to the
Class A, Class B, Class C and Class D shares will be invested together in a
single portfolio. The net asset value of each Class, however, will be
determined separately by subtracting each Class's accrued expenses and
liabilities. The net asset value per share will not be determined on Good
Friday and on such other federal and non-federal holidays as are observed by
the New York Stock Exchange.
Portfolio securities (other than short-term taxable debt securities,
futures and options) are valued for the Fund by an outside independent
pricing service approved by the Fund's Trustees. The service may utilize a
computerized grid matrix of tax-exempt securities and evaluations by its
staff in determining what it believes is the fair value of the Fund's
portfolio securities. The Board believes 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
services are more likely to approximate the fair value of such securities.
Short-term taxable debt securities with remaining maturities of sixty days
or less at time of purchase are valued at amortized cost, unless the Board
determines such does not reflect the securities' market value, in which case
these securities will be valued at their fair value as determined by the
Board of Trustees. Other taxable short-term debt securities with maturities
of more than sixty days will be valued on a mark to market basis until such
time as they reach a maturity of sixty 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' market value, in which case
these securities will be valued at their fair market value as determined by
the Board of 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 Board of 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 Board of 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 Board of Trustees.
SHAREHOLDER SERVICES
- -------------------------------------------------------------------------------
AUTOMATIC INVESTMENT OF DIVIDENDS AND DISTRIBUTIONS. All income dividends and
capital gains distributions are automatically paid in full and fractional
shares of the applicable Class of the Fund (or, if specified by the
shareholder, in shares of any other open-end Dean Witter Fund), unless the
shareholder requests that they be paid in cash. Shares so acquired are
acquired at net asset value and are not subject to the imposition of a
front-end sales charge or a CDSC (see "Redemptions and Repurchases"). Such
dividends and distributions will be paid, at the net asset value per share
(without sales charge), in shares of the applicable Class of the Fund (or in
cash if the shareholder so requests) on the monthly payment date, which will
be no later than the last business day of the month for which the dividend or
distribution is payable. Processing of dividend checks begins immediately
following the monthly payment date. Shareholders who have requested to
receive dividends in cash will normally receive their monthly dividend checks
during the first ten days of the following month.
INVESTMENT OF DIVIDENDS AND DISTRIBUTIONS RECEIVED IN CASH. Any shareholder
who receives a cash payment representing a dividend or capital gains
distribution may invest such dividend or distribution in shares of the
applicable Class at the net asset value per share next determined after
receipt by the Transfer Agent, by returning the check or the proceeds to the
Transfer Agent within thirty days after the payment date. Shares so acquired
are acquired at net asset value and are not subject to the imposition of a
front-end sales charge or a CDSC (see "Redemptions and Repurchases").
21
<PAGE>
EASYINVEST (SERVICE MARK). Shareholders may subscribe to EasyInvest, an
automatic purchase plan which provides for any amount from $100 to $5,000 to
be transferred automatically from a checking or savings account or following
redemption of shares of a Dean Witter money market fund, on a semi-monthly,
monthly or quarterly basis, to the Transfer Agent for investment in shares of
the Fund (see "Purchase of Fund Shares" and "Redemptions and
Repurchases--Involuntary Redemption").
SYSTEMATIC WITHDRAWAL PLAN. A systematic withdrawal plan (the "Withdrawal
Plan") is available for shareholders who own or purchase shares of the Fund
having a minimum value of $10,000 based upon the then current net asset
value. The plan provides for monthly or quarterly (March, June, September,
December) checks in any dollar amount, not less than $25, or in any whole
percentage of the account balance, on an annualized basis. Any applicable
CDSC will be imposed on shares redeemed under the Withdrawal Plan (see
"Purchase of Fund Shares"). Therefore, any shareholder participating in the
Withdrawal Plan will have sufficient shares redeemed from his or her account
so that the proceeds (net of any applicable CDSC) to the shareholder will be
the designated monthly or quarterly amount. Withdrawal plan payments should
not be considered as dividends, yields or income. If periodic withdrawal plan
payments continuously exceed net investment income and net capital gains, the
shareholder's original investment will be correspondingly reduced and
ultimately exhausted. Each withdrawal constitutes a redemption of shares and
any gain or loss realized must be recognized for federal income tax purposes.
Shareholders should contact their DWR or other Selected Broker-Dealer
account executive or the Transfer Agent for further information about any of
the above services.
EXCHANGE PRIVILEGE
Shares of each Class may be exchanged for shares of the same Class of any
other Dean Witter Multi-Class Fund without the imposition of any exchange
fee. Shares may also be exchanged for shares of the following funds: Dean
Witter Short-Term U.S. Treasury Trust, Dean Witter Limited Term Municipal
Trust, Dean Witter Short-Term Bond Fund, Dean Witter Intermediate Term U.S.
Treasury Trust and five Dean Witter funds which are money market funds (the
"Exchange Funds"). Class A shares may also be exchanged for shares of Dean
Witter Multi-State Municipal Series Trust and Dean Witter Hawaii Municipal
Trust, which are Dean Witter Funds sold with a front-end sales charge ("FSC
Funds"). Class B shares may also be exchanged for shares of Dean Witter
Global Short-Term Income Fund Inc. ("Global Short-Term") which is a Dean
Witter Fund offered with a CDSC. Exchanges may be made after the shares of
the Fund acquired by purchase (not by exchange or dividend reinvestment) have
been held for thirty days. There is no holding period for exchanges of shares
acquired by exchange or dividend reinvestment.
An exchange to another Dean Witter Multi-Class Fund, any FSC Fund, Global
Short-Term or any Exchange Fund that is not a money market fund is on the
basis of the next calculated net asset value per share of each fund after the
exchange order is received. When exchanging into a money market fund from the
Fund, shares of the Fund are redeemed out of the Fund at their next
calculated net asset value and the proceeds of the redemption are used to
purchase shares of the money market fund at their net asset value determined
the following business day. Subsequent exchanges between any of the money
market funds and any of the Dean Witter Multi-Class Funds, FSC Funds, Global
Short-Term or any Exchange Fund that is not a money market fund can be
effected on the same basis.
No CDSC is imposed at the time of any exchange of shares, although any
applicable CDSC will be imposed upon ultimate redemption. During the period
of time the shareholder remains in an Exchange Fund (calculated from the last
day of the month in which the Exchange Fund shares were acquired), the
holding period (for the purpose of determining the rate of the CDSC) is
frozen. If those shares are subsequently re-exchanged for shares of a Dean
Witter Multi-Class Fund or shares of Global Short-Term, the holding period
previously frozen when the first exchange was made resumes on the last day of
the month in which shares of a Dean Witter Multi-Class Fund or shares of
Global Short-Term are reacquired. Thus, the CDSC is based upon the time
(calculated as described above) the shareholder was invested in shares of a
Dean Witter Multi-Class Fund or in shares of Global Short-Term (see "Purchase
of Fund Shares"). In the case of exchanges of Class A shares which are
subject to a CDSC, the holding period also includes the time (calculated as
described above) the shareholder was invested in shares of a FSC Fund. In the
case of shares exchanged into an Exchange Fund on or after April 23, 1990,
upon a redemption of shares which results in a CDSC being imposed, a credit
(not to exceed the amount of the CDSC) will be given in an amount equal to
the Exchange Fund 12b-1 distribution fees incurred on or after that date
which are attributable to those shares. (Exchange Fund 12b-1 distribution
fees are described in the prospectuses for those funds.) Class B shares of
the Fund acquired in exchange for shares of Global Short-Term or Class B
shares of another Dean Witter Multi-Class Fund having a
22
<PAGE>
different CDSC schedule than that of this Fund will be subject to the higher
CDSC schedule, even if such shares are subsequently re-exchanged for shares
of the fund with the lower CDSC schedule. Class B shares of the Fund issued
in exchange for shares of National Municipal in connection with 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 for shares of
a fund with a higher CDSC schedule or (ii) having been exchanged for shares
of Global Short-Term or an Exchange Fund 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 Global
Short-Term or any of the Exchange Funds acquired in an exchange and then
subsequently re-exchanged back into the Fund, the Fund's CDSC schedule will
apply to redemptions of any of such shares.
ADDITIONAL INFORMATION REGARDING EXCHANGES. Purchases and exchanges should be
made for investment purposes only. A pattern of frequent exchanges may be
deemed by the Investment Manager to be abusive and contrary to the best
interests of the Fund's other shareholders and, at the Investment Manager's
discretion, may be limited by the Fund's refusal to accept additional
purchases and/or exchanges from the investor. Although the Fund does not have
any specific definition of what constitutes a pattern of frequent exchanges,
and will consider all relevant factors in determining whether a particular
situation is abusive and contrary to the best interests of the Fund and its
other shareholders, investors shoud be aware that the Fund and each of the
other Dean Witter Funds may in their discretion limit or otherwise restrict
the number of times this Exchange Privilege may be exercised by any investor.
Any such restriction will be made by the Fund on a prospective basis only,
upon notice to the shareholder not later than ten days following such
shareholder's most recent exchange. Also, the Exchange Privilege may be
terminated or revised at any time by the Fund and/or any of such Dean Witter
Funds for which shares of the Fund may be exchanged, upon such notice as may
be required by applicable regulatory agencies. Shareholders maintaining
margin accounts with DWR or another Selected Broker-Dealer are referred to
their account executive regarding restrictions on exchange of shares of the
Fund pledged in their margin account.
The current prospectus for each fund describes its investment objective(s)
and policies, and shareholders should obtain one and read it carefully before
investing. Exchanges are subject to the minimum investment requirement of
each Class of shares and other conditions imposed by each fund. In the case
of a shareholder holding a share certificate or certificates, no exchanges
may be made until all applicable share certificates have been received by the
Transfer Agent and deposited in the shareholder's account. An exchange will
be treated for federal income tax purposes as a redemption or repurchase of
shares, on which the shareholder may realize a capital gain or loss. However,
the ability to deduct capital losses on an exchange is limited in situations
where there is an exchange of shares within ninety days after the shares are
purchased. There are also limits on the deduction of losses after the payment
of exempt-interest dividends for shares held for less than six months (see
"Dividends, Distributions and Taxes"). The Exchange Privilege is only
available in states where an exchange may legally be made.
If DWR or another Selected Broker-Dealer is the current dealer of record
and its account numbers are part of the account information, shareholders may
initiate an exchange of shares of the Fund for shares of any of the Dean
Witter Funds (for which the Exchange Privilege is available) pursuant to this
Exchange Privilege by contacting their DWR or other Selected Broker-Dealer
account executive (no Exchange Privilege Authorization Form is required).
Other shareholders (and those shareholders who are clients of DWR or another
Selected Broker-Dealer but who wish to make exchanges directly by writing or
telephoning the Transfer Agent) must complete and forward to the Transfer
Agent an Exchange Privilege Authorization form, copies of which may be
obtained from the Transfer Agent, to initiate an exchange. If the
Authorization Form is used, exchanges may be made by contacting the Transfer
Agent at (800) 869-NEWS (toll-free). The Fund will employ reasonable
procedures to confirm that exchange instructions communicated over the
telephone are genuine. Such procedures may include requiring various forms of
personal identification such as name, mailing address, social security or
other tax identification number and DWR or other Selected Broker-Dealer
account number (if any). Telephone instructions may also be recorded. If such
procedures are not employed, the Fund may be liable for any losses due to
unauthorized or fraudulent instructions.
Telephone exchange instructions will be accepted if received by the
Transfer Agent between 9:00 a.m. and 4:00 p.m. New York time, on any day the
New York Stock Exchange is open. Any shareholder wishing to make an exchange
who has previously filed an Exchange Privilege Authorization Form and who is
unable to reach the Fund by telephone should contact his or her DWR or other
Selected Broker-Dealer account executive, if appropriate,
23
<PAGE>
or make a written exchange request (see "Redemptions and Repurchases").
Shareholders are advised that 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 Dean
Witter Funds in the past.
For further information regarding the Exchange Privilege, shareholders
should contact their DWR or other Selected Broker-Dealer account executive or
the Transfer Agent.
REDEMPTIONS AND REPURCHASES
- -------------------------------------------------------------------------------
REDEMPTION. Shares of each Class of the Fund can be redeemed for cash at any
time at the net asset value per share next determined less the amount of any
applicable CDSC in the case of Class A, Class B or Class C shares (see
"Purchase of Fund Shares"). If shares are held in a shareholder's account
without a share certificate, a written request for redemption to the Fund's
Transfer Agent at P.O. Box 983, Jersey City, NJ 07303 is required. If
certificates are held by the shareholder, the shares may be redeemed by
surrendering the certificates with a written request for redemption, along
with any additional information required by the Transfer Agent.
REPURCHASE. DWR and other Selected Broker-Dealers are authorized to
repurchase shares represented by a share certificate which is delivered to
any of their offices. Shares held in a shareholder's account without a share
certificate may also be repurchased by DWR and other Selected Broker-Dealers
upon the telephonic request of the shareholder. The repurchase price is the
net asset value next determined (see "Purchase of Fund Shares") after such
repurchase order is received by DWR or other Selected Broker-Dealer reduced
by any applicable CDSC.
The CDSC, if any, will be the only fee imposed by the Fund or the
Distributor. The offer by DWR and other Selected Broker-Dealers to repurchase
shares from shareholders may be suspended by them at any time. In that event,
shareholders may redeem their shares through the Fund's Transfer Agent as set
forth above under "Redemption."
PAYMENT FOR SHARES REDEEMED OR REPURCHASED. Payment for shares presented for
repurchase or redemption will be made by check within seven days after
receipt by the Transfer Agent of the certificate and/or written request in
good order. Such payment may be postponed or the right of redemption
suspended at times when normal trading is not taking place on the New York
Stock Exchange. If the shares to be redeemed have recently been purchased by
check, payment of the redemption proceeds may be delayed for the minimum time
needed to verify that the check used for investment has been honored (not
more than fifteen days from the time of receipt of the check by the Transfer
Agent). Shareholders maintaining margin accounts with DWR or another Selected
Broker-Dealer are referred to their account executive regarding restrictions
on redemption of shares of the Fund pledged in the margin account.
REINSTATEMENT PRIVILEGE. A shareholder who has had his or her share redeemed
or repurchased and has not previously exercised this reinstatement privilege
may, within 35 days after the date of the redemption or repurchase, reinstate
any portion or all of the proceeds of such redemption or repurchase in shares
of the Fund in the same Class from which such shares were redeemed or
repurchased, at their net asset value next determined after a reinstatement
request, together with the proceeds, is received by the Transfer Agent and
receive a pro rata credit for any CDSC paid in connection with such
redemption or repurchase.
INVOLUNTARY REDEMPTION. The Fund reserves the right, on sixty days' notice,
to redeem at net asset value the shares of any shareholder whose shares due
to redemptions by the shareholder have a value of less than $100, or such
lesser amount as may be fixed by the Board of Trustees or, in the case of an
account opened through EasyInvest, if after twelve months the shareholder has
invested less than $1,000 in the account. However, before the Fund redeems
such shares and sends the proceeds to the shareholder, it will notify the
shareholder that the value of the shares is less than the applicable amount
and allow the shareholder sixty days to make an additional investment in an
amount which will increase the value of the account to at least the
applicable amount before the redemption is processed. No CDSC will be imposed
on any involuntary redemption.
DIVIDENDS, DISTRIBUTIONS AND TAXES
- -------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS. The Fund declares dividends separately for each
Class from net investment income on each day the New York Stock Exchange is
open for business to shareholders of record as of the
24
<PAGE>
close of business the preceding business day. The amount of such dividends
may fluctuate from day to day. Such dividends are paid monthly. The Fund
intends to distribute all of its net investment income on an annual basis.
The Fund will distribute at least once each year all net realized
short-term capital gains in excess of any realized net long-term capital
losses, if any. The Fund intends to distribute all of its realized net
long-term capital gains, if any, in excess of any realized net short-term
capital losses and any available net capital loss carryovers, at least once
per fiscal year, although it may elect to retain all or part of such gains
for reinvestment. Taxable capital gains may be generated by the sale of
portfolio securities and by transactions in options and futures contracts
engaged in by the Fund.
All dividends and any capital gains distributions will be paid in
additional Fund shares of the same Class and automatically credited to the
shareholder's account without issuance of a share certificate unless the
shareholder requests in writing that all dividends be paid in cash. Shares
acquired by dividend and distribution reinvestments will not be subject to
any front-end sales charge or CDSC. Class B shares acquired through dividend
and distribution reinvestments will become eligible for conversion to Class A
shares on a pro rata basis. Distributions paid on Class A and Class D shares
will be higher than for Class B and Class C shares because distribution fees
paid by Class B and Class C shares are higher. (See "Shareholder
Services--Automatic Investment of Dividends and Distributions.") Any
dividends declared in the last quarter of any calendar year which are paid in
the following calendar year prior to February 1 will be deemed received by
the shareholder in the prior calendar year.
TAXES. Because the Fund intends to distribute all of its net investment
income and capital gains to shareholders and intends to otherwise continue to
qualify as a regulated investment company under Subchapter M of the Internal
Revenue Code, it is not expected that the Fund will be required to pay any
federal income tax.
The Fund intends to qualify to pay "exempt-interest dividends" to its
shareholders by maintaining, as of the close of each quarter of its taxable
year, at least 50% of the value of its total assets in tax-exempt securities.
If the Fund satisfies such requirement, distributions from net investment
income to shareholders, whether taken in cash or reinvested in additional
shares, will be excludable from gross income for federal income tax purposes
to the extent net investment income is represented by interest on tax-exempt
securities. 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 Internal Revenue Code may subject interest received
on certain otherwise tax-exempt securities to an alternative minimum tax.
This alternative minimum tax may be incurred due to interest received on
certain "private activity bonds" (in general, bonds that benefit
non-government entities) issued after August 7, 1986 which, although
tax-exempt, are used for purposes other than those generally performed by
government units (e.g., bonds used for commercial or housing purposes).
Income received on such bonds is classified as a "tax preference item," under
the alternative minimum tax, for both individual and corporate investors. The
Fund anticipates that a portion of its investments will be made in such
"private activity bonds," with the result that 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. In addition, 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.
Under the Revenue Reconciliation Act of 1993, all or a portion of the
Fund's gain from the sale or redemption of tax-exempt obligations purchased
at a market discount after April 30, 1993 will be treated as ordinary income
rather than capital gain. This rule may increase the amount of ordinary
income dividends received by shareholders.
After the end of the calendar year, the Fund will mail to its shareholders
a statement indicating the percentage of the dividend distributions for such
year which constitutes exempt-interest dividends and the percentage, if any,
that is taxable, and to what extent the taxable portion is long-term or
short-term capital gain. Shareholders will also be notified of their
proportionate share of long-term capital gains distributions that are
eligible for a reduced rate of tax under the Taxpayer Relief Act of 1997.
Shareholders will normally 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, if any. 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. To avoid being subject to a 31% federal backup withholding tax on
taxable dividends, capital gains distributions and proceeds of redemptions or
repurchases, shareholders' taxpayer identification numbers must be furnished
and certified as to accuracy.
25
<PAGE>
Any loss on the sale or exchange of shares of the Fund which are held for
six months or less is disallowed to the extent of the amount of any
exempt-interest dividend paid with respect to such shares. Treasury
Regulations may provide for a reduction in such required holding periods. If
a shareholder receives a distribution that is taxed as a long-term capital
gain on shares held for six months or less and sells those shares at a loss,
the loss will be treated as a long-term capital loss.
Interest on indebtedness incurred by shareholders to purchase or carry
shares of an investment company paying exempt-interest dividends, such as the
Fund, will not be deductible by the investor for federal income tax purposes.
The exemption of interest income for federal income tax purposes does not
necessarily result in exemption under the income or other tax laws of any
state or local taxing authority. Thus, shareholders of the Fund may be
subject to state and local taxes on exempt-interest dividends.
The Fund may at times make payments from sources other than income or net
capital gains. Payments from such sources will, in effect, represent a return
of a portion of each shareholder's investment. All, or a portion, of such
payments will not be taxable to share holders.
Shareholders should consult their tax advisers as to the applicability of
the above to their own tax situation.
PERFORMANCE INFORMATION
- -------------------------------------------------------------------------------
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. Both the yield and the
total return of the Fund are based on historical earnings and are not
intended to indicate future performance. The yield of each Class of the Fund
is computed by dividing the Class's net investment income over a 30-day
period by an average value (using the average number of shares entitled to
receive dividends and the maximum offering price per share at the end of the
period), all in accordance with applicable regulatory requirements. Such
amount is compounded for six months and then annualized for a twelve-month
period to derive the Fund's yield for each Class. The Fund may also quote
tax-equivalent yield, which is calculated by determining the pre-tax yield
for each Class which, after being taxed at a stated rate, would be equivalent
to the yield determined as described above.
The "average annual total return" of the Fund refers to a figure
reflecting the average annualized percentage increase (or decrease) in the
value of an initial investment in a Class of the Fund of $1,000 over periods
of one, five and ten years. Average annual total return reflects all income
earned by the Fund, any appreciation or depreciation of the Fund's assets,
all expenses incurred by the applicable Class and all sales charges which
would be incurred by shareholders, for the stated periods. It also assumes
reinvestment of all dividends and distributions paid by the Fund.
In addition to the foregoing, 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. Such calculations may or
may not reflect the deduction of any sales charge which, if reflected, would
reduce the performance quoted. The Fund may also advertise the growth of
hypothetical investments of $10,000, $50,000 or $100,000 in each Class of
shares of the Fund. The Fund from time to time may also advertise its
performance relative to certain performance rankings and indexes compiled by
independent organizations (such as mutual fund performance rankings of Lipper
Analytical Services, Inc.).
Prior to July 28, 1997, the Fund offered only one Class of shares. Because
the distribution arrangement for Class A most closely resembles the
distribution arrangement applicable prior to the implementation of multiple
classes, historical performance information may be restated to reflect the
current maximum sales charge applicable to Class A as well as the imposition
of an ongoing 12b-1 fee. In addition, because all shares of the Fund held
prior to July 28, 1997 have been designated Class D shares, the Fund's
historical performance may also be restated to reflect the absence of any
sales charge in the case of Class D shares.
ADDITIONAL INFORMATION
- -------------------------------------------------------------------------------
VOTING RIGHTS. All shares of beneficial interest of the Fund are of $.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
26
<PAGE>
on any proposed material increase in Class A's expenses, if such proposal is
submitted separately to Class A shareholders. Also, as discussed herein,
Class A, Class B and Class C bear the expenses related to the distribution of
their respective shares.
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 Act or the Declaration of Trust. Under certain
circumstances the Trustees may be removed by action of the Trustees or by the
shareholders.
Under Massachusetts law, shareholders of a business trust may, under
certain 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 Fund obligations include such disclaimer, and provides
for indemnification and reimbursement of expenses out of the Fund's property
for any share holder 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's being unable to meet its
obligations is remote and, in the opinion of Massachusetts counsel to the
Fund, the risk to Fund shareholders of personal liability is remote.
CODE OF ETHICS. Directors, officers and employees of InterCapital, Dean
Witter Services Company Inc. and the Distributor are subject to a strict Code
of Ethics adopted by those companies. The Code of Ethics is intended to
ensure that the interests of shareholders and other clients are placed ahead
of any personal interest, that no undue personal benefit is obtained from a
person's employment activities and that actual and potential conflicts of
interest are avoided. To achieve these goals and comply with regulatory
requirements, the Code of Ethics requires, among other things, that personal
securities transactions by employees of the companies be subject to an
advance clearance process to monitor that no Dean Witter Fund is engaged at
the same time in a purchase or sale of the same security. The Code of Ethics
bans the purchase of securities in an initial public offering, and also
prohibits engaging in futures and options transactions and profiting on
short-term trading (that is, a purchase within sixty days of a sale or a sale
within sixty days of a purchase) of a security. In addition, investment
personnel may not purchase or sell a security for their personal account
within thirty days before or after any transaction in any Dean Witter Fund
managed by them. Any violations of the Code of Ethics are subject to
sanctions, including reprimand, demotion or suspension or termination of
employment. The Code of Ethics comports with regulatory requirements and the
recommendations in the 1994 report by the Investment Company Institute
Advisory Group on Personal Investing.
MASTER/FEEDER CONVERSION. The Fund reserves the right to seek to achieve its
investment objective by investing all of its investable assets in a
diversified, open-end management investment company having the same
investment objective and policies and substantially the same investment
restrictions as those applicable to the Fund.
SHAREHOLDER INQUIRIES. All inquiries regarding the Fund should be directed to
