Management          The Investment Manager receives a monthly fee at the annual rate of 0.55 of 1% of daily net assets, scaled down
Fee                 on assets over $500 million. The fee should not be compared with fees paid by other investment companies without

- ------------------------------------------------------------------------------------------------------------------------------------
Distributor and     Dean Witter Distributors Inc. (the "Distributor"). The Fund has adopted a distribution plan pursuant to Rule
Distribution 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 0.20% 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 16 and 24).
- ------------------------------------------------------------------------------------------------------------------------------------
Alternative         Four classes of shares are offered:
Purchase
Arrangements        - 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 16, 20 and 24).

<TABLE>
<S>                 <C>
                    - 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 0.75% of the lesser
                    of: (a) the average daily net sales of the Fund's Class B shares or (b) the average daily net assets of Class B.
                    All shares of the Fund held prior to July 28, 1997 have been designated Class B shares. Shares held before May
                    1, 1997 will convert to Class A shares in May, 2007. In all other instances, Class B shares convert to Class A
                    shares approximately ten years after the date of the original purchase (see pages 16, 22 and 24).
                    - 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 0.75% of average daily net assets of the Class (see pages 16 and 24).
                    - 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 16 and 24).
- ------------------------------------------------------------------------------------------------------------------------------------
Dividends and       Dividends from net investment income are declared daily and paid monthly; capital gains, if any, may be
Capital Gains       distributed at least annually or retained for reinvestment by the Fund. Dividends and capital gains
Distributions       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 26 and 30).
- ------------------------------------------------------------------------------------------------------------------------------------
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-SM-, if after twelve months the shareholder has invested less than
                    $1,000 in the account (see page 29).
- ------------------------------------------------------------------------------------------------------------------------------------
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 also may
                    invest in futures and options for portfolio hedging purposes. Futures and options may be considered speculative
                    in nature and may involve greater risks than those customarily assumed by certain other investment companies
                    which do not invest in such instruments. Since the Fund concentrates its investments in New York tax-exempt
                    securities, the Fund is affected by any political, economic or regulatory developments affecting the ability of
                    New York issuers to pay interest or repay principal (see pages 11-15).

(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 0.20% 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 0.75% DISTRIBUTION FEE (SEE "PURCHASE OF FUND
    SHARES--ALTERNATIVE PURCHASE ARRANGEMENTS").
 
   
(7) THERE WERE NO OUTSTANDING SHARES OF CLASS A, CLASS C OR CLASS D 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."

    The purpose of this table is to assist the investor in understanding the
various costs and expenses that an investor in the Fund will bear directly or
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."
 
    Long-term shareholders of Class B and Class C may pay more in sales charges,
including distribution fees, than the economic equivalent of the maximum
front-end sales charges permitted by the NASD.

diversified management investment company. The Fund is a trust of the type
commonly known as a "Massachusetts business trust" and was organized under the
laws of Massachusetts on January 17, 1985.
 
   
    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, twenty-eight
of which are listed on the New York Stock Exchange, with combined total assets
including this Fund of approximately $106 billion as of February 28, 1998. The
Investment Manager also manages portfolios of pension plans, other institutions
and individuals which aggregated approximately $4 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
Board of Trustees reviews 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 by applying the
following annual rates to the net assets of the Fund determined as of the close
of each business day: 0.55% of the portion of the daily net assets not exceeding
$500 million and 0.525% of the portion of the daily net assets exceeding $500
million. For the fiscal year ended December 31, 1997, the Fund accrued total
compensation to the Investment Manager amounting to 0.55% of the Fund's average
daily net assets and the total expenses of Class B amounted to 1.42% of the
Fund's average daily net assets of Class B. Shares of Class A, Class C and Class
D 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, New York State and New York City income
tax, consistent with the preservation of capital. There is no assurance that
this objective will be achieved. The Fund seeks to achieve its investment
objective by investing its assets in accordance with the following policies:
 
   1. As a fundamental policy the Fund must have at least 80% of its total
assets invested in New York tax-exempt securities, except as stated in paragraph
(3) below. New York tax-exempt securities consist of obligations of New York
State, its political subdivisions, authorities and corporations, as well as any
debt obligations (certain governmental entities and territories such as Puerto
Rico, Guam and
 
                                       9
<PAGE>
the Virgin Islands) that generate interest income which is exempt from federal,
New York State and New York City income taxes. New York tax-exempt securities
consist of Municipal Bonds and Municipal Notes ("Municipal Obligations") and
Municipal Commercial Paper. Only New York tax-exempt securities which satisfy
the following standards may be purchased by the Fund: (a) Municipal Bonds which
are rated at the time of purchase within the four highest grades by Moody's
Investors Service, Inc. ("Moody's") or Standard & Poor's Corporation ("S&P");
(b) Municipal Notes of issuers 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; (c) Municipal Commercial Paper which at the time of purchase is rated
P-1 by Moody's or A-1 by S&P; and (d) unrated securities which at the time of
purchase are judged by the Investment Manager to be of comparable quality to the
securities described above. For a description of Moody's and S&P's ratings, see
the Appendix to the Statement of Additional Information.
 
   2. 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 ("AMT") will not be included
in the 80% total described in paragraph 1 above. (See "Dividends, Distributions
and Taxes.") As such, the remaining portion of the Fund's total assets may be
invested in tax-exempt securities subject to the AMT.
 
   3. Up to 20% of the Fund's total assets may be invested in taxable money
market instruments, non-New York tax-exempt securities, futures and options and
tax-exempt securities subject to the AMT. However, the Fund may temporarily
invest more than 20% of its total assets in taxable money market instruments,
non-New York tax-exempt securities and tax-exempt securities subject to the AMT,
in order to maintain a "defensive" posture when, in the opinion of the
Investment Manager, it is advisable to do so because of market conditions. Only
those non-New York tax-exempt securities which satisfy the standards set forth
in paragraph (1) for New York tax-exempt securities may be purchased by the
Fund. The types of taxable money market instruments in which the Fund may invest
are limited to the following short-term fixed income securities (maturing in one
year or less from the time of purchase): (i) obligations of the United States
Government, its agencies, instrumentalities or authorities; -ii) commercial
paper rated P-1 or higher by Moody's or A]1 or higher by S&P; (iii) certificates
of deposit of domestic banks with assets of $1 billion or more; and (iv)
repurchase agreements with respect to portfolio securities.
 
    Municipal Obligations are debt obligations of a state, its 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 is a short-term obligation of a
municipality. Any Municipal Obligation which depends directly or indirectly on
the credit of the Federal Government, its agencies or instrumentalities shall be
considered to have a rating of Aaa/AAA. An obligation shall be considered a New
York tax-exempt security only if, in the opinion of bond counsel, the interest
payable thereon is exempt from federal, New York State and New York City income
tax. The Fund may also 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.
 
    The two principal classifications of Municipal Obligations and Commercial
Paper are "general obligation" and "revenue" bonds, notes 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 governmental units. Revenue
bonds, notes or commercial paper are payable from the revenues
 
                                       10
<PAGE>
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.
 
RISK CONSIDERATIONS
 
    Investments in municipal bonds rated either Baa by Moody's or BBB by S&P
(investment grade bonds--the lowest rated permissible investments by the Fund)
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.
 
    Included within the revenue category of bonds described above 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 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 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
 
                                       11
<PAGE>
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
share.
 
    VARIABLE RATE OBLIGATIONS.  The interest rates payable on certain securities
in which the Fund may invest are not fixed and may fluctuate based upon changes
in market rates. 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.
 
    WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS.  From
time to time, in the ordinary course of business, the Fund may purchase
securities on a when-issued or delayed delivery basis, or may purchase or sell
securities on a forward commitment basis. When such transactions are negotiated,
the price is fixed at the time of the commitment, but delivery and payment can
take place a month or more after the date of the commitment. There is no overall
limit on the percentage of the Fund's assets which may be committed to the
purchase of securities on a when-issued, delayed delivery or forward commitment
basis. An increase in the percentage of the Fund's assets committed to the
purchase of securities on a when-issued, delayed delivery or forward commitment
basis may increase the volatility of 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.
 
    The Fund may enter into financial futures contracts, options on such futures
and municipal bond index futures contracts for hedging purposes.
 
    FINANCIAL FUTURES CONTRACTS AND OPTIONS ON FUTURES.  The Fund may invest in
financial futures contracts and related options thereon. The Fund may sell a
financial futures contract, 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
financial futures contract or a call option thereon 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 would create an obligation by the Fund, as purchaser,
to take delivery of the specific type of financial instrument at a specified
future time at a specified price. The specific securities delivered or taken,
respectively, at settlement date, would not be determined until 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.
 
                                       12
<PAGE>
    Although the terms of financial 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 financial futures contract, which requires the parties to buy and
sell a security on a set date, an option on such 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 no daily payments of cash to
reflect the change in the value of the underlying contract as there is 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 financial 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 will be
increased by the fact that financial futures contracts in which the Fund may
invest are on taxable securities rather than on tax-exempt 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 his
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 financial 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 such options 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 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 related options thereon if
immediately thereafter the amount committed to margin plus the amount paid for
option premiums exceeds 5% of the value of the Fund's total assets. The Fund may
not purchase or sell futures contracts or related options if immediately
thereafter more than one-third of its net assets would be hedged.
 
                                       13
<PAGE>
   
    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 fo 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 service 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.
    
 
    Except as specified, the investment policies noted above are not fundamental
policies and may be changed without shareholder approval.
 
   
RISK CONSIDERATIONS RELATING TO NEW YORK
TAX-EXEMPT SECURITIES
    
 
    Since the Fund concentrates its investments in New York tax-exempt
securities, the Fund is affected by any political, economic or regulatory
developments affecting the ability of New York tax-exempt issuers to pay
interest or repay principal. Investors should be aware that certain issuers of
New York tax-exempt securities have experienced serious financial difficulties
in recent years. A reoccurrence of these difficulties may impair the ability of
certain New York issuers to maintain debt service on their obligations.
 
    The fiscal stability of New York State (the "State") is related to the
fiscal stability of the State's municipalities, its Agencies and Authorities
(which generally finance, construct and operate revenue-producing public benefit
facilities). This is due in part to the fact that Agencies, Authorities and
local governments in financial trouble often seek State financial assistance.
The experience has been that if New York City (the "City") or any of the
Agencies or Authorities suffers serious financial difficulty, both the ability
of the State, the City, the State's political subdivisions, the Agencies and the
Authorities to obtain financing in the public credit markets and the market
price of outstanding New York tax-exempt securities are adversely affected.
 
    Over the long term, the State and City face potential economic problems. The
City accounts for a large portion of the State's population and personal income,
and the City's financial health affects the State in numerous ways. The City
continues to require significant financial assistance from the State. The City
depends on State aid both to enable the City to balance its budget and to meet
its cash requirements. The State could also be affected by the ability of the
City to market its securities successfully in the public credit markets.
 
    The economic and financial condition of the State also may be affected by
various financial, social, economic and political factors. Such factors can be
very complex, may vary from fiscal year to fiscal year and are frequently the
result of actions taken not only by the State and its agencies and
instrumentalities, but also by entities, such as the Federal government, that
are not under the control of the State.
 
    On January 13, 1992, Standard & Poor's reduced its ratings on the State's
general obligation bonds from A to A- and, in addition, reduced its
 
                                       14
<PAGE>
   
ratings on the State's moral obligation, lease purchase, guaranteed and
contractual obligation debt. Standard & Poor's also continued its negative
rating outlook assessment on State general obligation debt. On April 26, 1993,
Standard & Poor's revised the rating outlook assessment to stable. On February
14, 1994, Standard & Poor's raised its outlook to positive and, on August 5,
1996, confirmed its A- rating. On August 28, 1997, Standard & Poor's revised its
ratings on the State's general obligation bonds from A- to A and, in addition,
revised its ratings on the State's moral obligation, lease purchase, guaranteed
and contractual obligation debt. On January 6, 1992, Moody's reduced its ratings
on outstanding limited-liability State lease purchase and contractual
obligations from A to Baa1. On February 10, 1997, Moody's confirmed its A2
rating on the State's general obligation long-term indebtedness.
    
 
    For a more detailed discussion of the risks of investing in New York
tax-exempt securities, see the Statement of Additional Information.
 
   
    The summary information furnished above and in the Statement of Additional
Information is based on official statements relating to offerings of New York
issuers of municipal securities on or prior to September 29, 1997 with respect
to offerings of the State and September 30, 1997 with respect to offerings of
the City, and it does not purport to be a complete description of the
considerations contained therein. No representation is made as to the accuracy
of such information.
    
 
PORTFOLIO MANAGEMENT
 
   
    The Fund is managed by the Investment Manager with a view to achieving its
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; and 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 January 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,
qualities and purpose. Securities purchased by the Fund are, generally, sold by
dealers acting as principal for their own accounts.
 
   
    Pursuant to an order issued by the Securities and Exchange Commission, the
Fund may effect principal transactions in certain taxable money market
instruments with DWR. In addition, the Fund may incur brokerage commissions on
transactions conducted through DWR, Morgan Stanley and Co. Incorporated and
other brokers and dealers that are affiliates of InterCapital.
    
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    The investment restrictions listed below are among the restrictions that
have been adopted by the Fund as fundamental policies. Under the Investment
Company Act of 1940, as amended (the
 
                                       15
<PAGE>
"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.
 
    The Fund may not:
   1. With respect to 75% of its total assets, purchase securities of any issuer
if immediately thereafter more than 5% of the Fund's total assets would be
invested in securities of such issuer (other than obligations issued or
guaranteed by the United States Government, its agencies or instrumentalities or
by the State of New York or its political subdivisions).
 
   2. Purchase more than 10% of all outstanding taxable debt securities of any
one issuer (other than obligations issued, or guaranteed as to principal and
interest, by the United States Government, its agencies or instrumentalities).
 
   3. Invest more than 25% of the value of its total assets in 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 issued by the State of New York or its political
subdivisions (industrial development and pollution control bonds are grouped
into industries based upon the business in which the issuers of such obligations
are engaged).
 
    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. Shares of the Fund are distributed by Dean Witter Distributors
Inc. (the "Distributor"), an affiliate of the Investment Manager, pursuant to a
Distribution Agreement between the Fund and the Distributor and are 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 and other Dean Witter Funds that
are multiple class funds ("Dean Witter
 
                                       16
<PAGE>
   
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 New York
Tax-Free Income Fund, directly to Morgan Stanley Dean Witter Trust FSB
("Transfer Agent"or "MSDW Trust") at P.O. Box 1040, Jersey City, New Jersey
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-SM-, 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 investments 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 or
administrative 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 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 or a Selected Broker-Dealer
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
when 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 at the time of
their sale 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 the Distributor reserve the right to reject any purchase orders.
 
    ANALOGOUS DEAN WITTER FUNDS.  The Distributor and the Investment Manager
serve in the same capacities for Dean Witter Multi-State Municipal Series
Trust-New York Series, an open-end investment company with investment objectives
and policies similar to those of the Fund. Shares of Dean Witter Multi-State
Municipal Series Trust-New York Series, are offered to the public with a sales
charge imposed at the time of purchase. The Classes of the Fund and Dean Witter
Multi-State Municipal Series Trust, New York Series have differing fees and
expenses, which will affect performance. Investors who would like to receive a
prospectus for Dean Witter Multi-State Municipal Series Trust-New York Series,
should call the telephone numbers listed on the front cover of this Prospectus,
or may call their account executive for additional information.
 
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
 
                                       17
<PAGE>
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 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 0.75% of
the lesser of: (a) the average daily aggregate gross sales of the Fund's Class B
shares since the inception of the Fund (not including reinvestments of dividends
or capital gains distributions), less the average daily aggregate net asset
value of the Fund's Class B shares redeemed since the Fund's inception upon
which a CDSC has been imposed or waived, or (b) 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 0.75% 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
 
                                       18
<PAGE>
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 significantly 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 0.75% (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.
 
    Set forth below is a chart comparing the sales charge, 12b-1 fees and
conversion options applicable to each Class 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 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
 
                                       20
<PAGE>
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.
 
                                       21
<PAGE>
    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 0.75% of the lesser of: (a) the average daily aggregate
gross sales of the Fund's Class B shares since the inception of the Fund (not
including reinvestments of dividends or capital gains distributions), less the
average daily aggregate net asset value of the Fund's Class B shares redeemed
since the Fund's inception upon which a CDSC has been imposed or waived, or (b)
the average daily net assets of Class B.
 
    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:

    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 other open-end investment
companies for which InterCapital serves as investment manager (collectively,
with the Fund, the "Dean Witter Funds") sold with a front-end sales charge 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
 
                                       22
<PAGE>
    (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.
 
    CONVERSION TO CLASS A SHARES.  All shares of the Fund held prior to July 28,
1997 have been designated Class B shares. Shares held before May 1, 1997 will
convert to Class A shares in May, 2007. In all other instances 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, provided that shares originally purchased before
May 1, 1997 will convert to Class A shares in May, 2007. The conversion of
shares purchased on or after May 1, 1997 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
 
                                       23
<PAGE>
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 0.75%
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. Investors who require a $5 million minimum
initial investment to qualify to purchase Class 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
 
    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 0.75% 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 0.75% of the lesser of: (a) the average daily
aggregate gross sales of the Fund's Class B shares since the inception of the
Fund (not including reinvestments of dividends or capital gains distributions),
less the average daily aggregate net asset value of the Fund's Class B shares
redeemed since the Fund's inception upon which a CDSC has been imposed or
waived, or (b) 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
 
                                       24
<PAGE>
Class C shares, a portion of the fee payable pursuant to the Plan, equal to
0.20% 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 year ended December 31, 1997, Class B shares of the Fund
accrued payments under the Plan amounting to $1,337,215, which amount is equal
to 0.75% of the average daily net assets of Class B for the fiscal year. These
payments were calculated pursuant to clause (b) of the compensation formula
under the Plan. All shares held prior to July 28, 1997 have been designated
Class B shares. For the fiscal period July 28 through December 31, 1997, Class A
and Class C shares of the Fund accrued payments under the Plan amounting to $60
and $210, respectively, which amounts on an annualized basis are equal to 0.25%
and 0.75% of the average daily net assets of Class A 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
$1,970,148 at December 31, 1997, which was equal to 1.16% of the net assets of
Class B on such date. 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 0.75% of the average daily net
assets of Class A or Class C, respectively, will not be reimbursed by the Fund
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 to account
executives at the time of sale totalled $736 in the case of Class C at December
31, 1997, which amount was equal to 0.68% of the net assets of
    
 
                                       25
<PAGE>
   
Class C on such date, and that there were no such expenses that may be
reimbursed in the subsequent year in 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 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 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.
 
    Certain of the Fund's portfolio securities may be valued for the Fund by an
outside independent pricing service approved by the Fund's Trustees. The service
utilizes 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
service are more likely to approximate the fair value of such securities.
 
    Short-term taxable debt securities with remaining maturities of sixty days
or less to maturity 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 market value as determined by
the Board of Trustees. The value of other assets will be determined in good
faith under procedures established by and under the supervision of the 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 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 check 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
 
                                       26
<PAGE>
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").
 
    EASYINVEST.-SM-  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
Repurchase--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 Withdrawal Plan provides for monthly or quarterly (March, June, September
and December) checks in any dollar amount, not less than $25 or in any whole
percentage of the account balances 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 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
waiting 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
 
                                       27
<PAGE>
   
the period of time the shareholder remains in an Exchange Fund (calculated from
the last day of the month in which the 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 of the Fund exchanged into the Exchange Funds 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 prospectus 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 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.
    
 
    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 should 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 any 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 the same as a repurchase or redemption of shares
on which the shareholder has realized a capital gain or loss. However, the
ability to deduct capital losses on an exchange may be 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
 
                                       28
<PAGE>
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 other 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 in writing or 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 is
unable to reach the Fund by telephone should contact his or her DWR or other
Selected Broker-Dealer account executive, if appropriate, or make a written
exchange request. 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 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 of redemption, along with any additional information required by
the Transfer Agent.
 
    REPURCHASE.  DWR or 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 or other Selected Broker-Dealers upon
the telephonic request of the shareholder. The repurchase price is the net asset
value next computed (see "Purchase of Fund Shares") after such repurchase order
is received by DWR or other Selected Broker-Dealers, reduced by any applicable
CDSC.
 
                                       29
<PAGE>
   
    The CDSC, if any, will be the only fee imposed by the Fund or the
Distributor. The offer by DWR or other Selected Broker-Dealers to repurchase
shares may be suspended without notice 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 under
unusual circumstances. 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 other Selected
Broker-Dealers 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 shares
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 to redeem, on sixty
days' notice and at net asset value, the shares of any shareholder (other than
shares held in an Individual Retirement Account or Custodial Account under
Section 403(b)(7) of the Internal Revenue Code) whose shares have a value of
less than $100 as a result of redemptions or repurchases, 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 him or her
sixty days to make an additional investment in an amount which will increase the
value of his or her 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 of shares from net investment income on each day the New York Stock
Exchange is open for business to shareholders of record as of the 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 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
shares of the same Class
 
                                       30
<PAGE>
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 year.
 
   
    TAXES.  Because the Fund currently intends to distribute substantially all
of its net investment income and net short-term capital gains to shareholders
and intends to otherwise comply with all the provisions of Subchapter M of the
Internal Revenue Code (the "Code") to qualify as a regulated investment company,
it is not expected that the Fund will be required to pay any federal income tax.
Taxable capital gains may be generated by transactions in options and futures
contracts engaged in by the Fund.
    
 
    The Fund intends to continue 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.
 
   
    Individual shareholders who are New York residents will not incur any
federal, New York State or New York City income tax on the amount of
exempt-interest dividends received by them from the Fund which represents a
distribution of income from New York tax-exempt securities whether taken in cash
or reinvested in additional shares. 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. Within sixty days after the end of
its taxable year, the Fund will mail to shareholders a statement indicating the
percentage of the dividend distributions for such taxable year which constitutes
exempt-interest dividends and the percentage, if any, that is taxable.
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.
    
 
    The 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 "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 governmental 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. A
portion of the Fund's investments may 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 have to include a portion of 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
 
                                       31
<PAGE>
as ordinary income rather than capital gain. This rule may increase the amount
of ordinary income dividends received by shareholders.
 
    Shareholders will normally be subject to federal, New York State or New York
City income tax on dividends paid from interest income derived from taxable
securities and on distributions of net capital gains. For federal and New York
State or New York City income tax purposes, distributions of net long-term
capital gains, if any, are taxable to shareholders as long-term capital gains,
regardless of how long the shareholder has held the Fund shares and regardless
of whether the distribution is received in additional shares or in cash.
Distributions from investment income and capital gains, including
exempt-interest dividends, may be subject to New York franchise taxes if
received by a corporation doing business in New York, to state taxes in states
other than New York and to local taxes. To avoid being subject to a 31% backup
withholding tax on taxable dividends and capital gains distributions and the
proceeds of redemptions and repurchases, shareholders' taxpayer identification
numbers must be furnished and certified as to accuracy.
 
    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 shareholders.
 
    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 moths 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 or related parties 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
or state or city personal income tax purposes.
 
    The foregoing relates to federal income taxation and to New York State and
New York City personal income taxation as in effect as of the date of this
prospectus. 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 its 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
 
                                       32
<PAGE>
over a period of one, five, ten years or over the life of the Fund. 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 and $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.).
 
ADDITIONAL INFORMATION
- --------------------------------------------------------------------------------
 
    VOTING RIGHTS.  All shares of beneficial interest of the Fund are of $0.01
par value and are equal as to earnings, assets and voting privileges except that
each Class will have exclusive voting privileges with respect to matters
relating to distribution expenses borne solely by such Class or any other matter
in which the interests of one Class differ from the interests of any other
Class. In addition, Class B shareholders will have the right to vote on any
proposed material increase in Class A's expenses, if such proposal is submitted
separately to Class A shareholders. Also, 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, under
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 shareholder held
personally liable for the obligations of the Fund. Thus, the risk of a
shareholder incurring financial loss on account of shareholder liability is
limited to circumstances in which the Fund itself would be unable to meet its
obligations. Given the above limitations on shareholder personal liability and
the nature of the Fund's assets and operations, the possibility of the Fund'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
 
                                       33
<PAGE>
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 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 the Fund at the telephone numbers or address set forth on the front cover of
this prospectus.

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
THE FUND
 
    The Fund is a Fund of the type commonly known as a "Massachusetts business
trust" and was organized under the laws of the Commonwealth of Massachusetts on
January 17, 1985.
 
THE INVESTMENT MANAGER
 
   
    Dean Witter InterCapital Inc., a Delaware corporation (the "Investment
Manager" or "InterCapital"), whose address is Two World Trade Center, New York,
New York 10048, is the Fund's Investment Manager. InterCapital is a wholly-owned
subsidiary of Morgan Stanley, Dean Witter & Co. ("MSDW"), a Delaware
Corporation. In an internal reorganization which took place in January, 1993,
InterCapital assumed the investment advisory, administrative and management
activities previously performed by the InterCapital Division of Dean Witter
Reynolds Inc. ("DWR"), a broker-dealer affiliate of InterCapital. (As
hereinafter used in this Statement of Additional Information, the terms
"InterCapital" and "Investment Manager" refer to DWR's InterCapital Division
prior to the internal reorganization and Dean Witter InterCapital Inc.
thereafter.) The daily management of the Fund and research relating to the
Fund's portfolio is conducted by or under the direction of officers of the Fund
and of the Investment Manager, subject to periodic review by the Fund's Board of
Trustees. Information as to these trustees and officers is contained under the
caption "Trustees and Officers."

Income Opportunities Trust III, Prime Income Trust and Municipal Premium Income
Trust. The foregoing investment companies, together with the Fund, are
collectively referred to as the Dean Witter Funds. In addition, Dean Witter
Services Company Inc. ("DWSC"), a wholly-owned subsidiary of InterCapital,
serves as manager for the following companies for which TCW Funds Management
Inc. is the investment adviser: TCW/DW North American Government Income Trust,
TCW/DW Latin American Growth Fund, TCW/DW Income and Growth Fund, TCW/DW Small
Cap Growth Fund, TCW/DW Total Return Trust, TCW/DW Mid-Cap Equity Trust, TCW/DW
Global Telecom Trust, TCW/DW Emerging Markets Opportunities Trust, TCW/DW Term
Trust 2000, TCW/DW Term Trust 2002 and TCW/DW Term Trust 2003 (the "TCW/DW
Funds"). InterCapital also serves as: (i) administrator of The BlackRock
Strategic Term Trust Inc., a closed-end investment company; (ii)
sub-administrator of Templeton Global Governments Income Trust, a closed-end
investment company; and (iii) investment adviser of Offshore Dividend Growth
Fund and Offshore Money Market Fund, mutual funds established under the laws of
the Cayman Islands and available only to investors who are participants in DWR's
International Active Assets Account program and are neither citizens nor
residents of the United States.
    
 
    Pursuant to an Investment Management Agreement (the "Agreement") with the
Investment Manager, the Fund has retained the Investment Manager to manage the
investment of the Fund's assets, including the placing of orders for the
purchase and sale of portfolio securities. The Investment Manager obtains and
evaluates such information and advice relating to the economy, securities
markets, and specific securities as it considers necessary or useful to
continuously manage the assets of the Fund in a manner consistent with its
investment objective and policies.
 
    Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes, at its own expense, such office space, facilities,
equipment, clerical help, bookkeeping and certain legal services as the Fund may
reasonably require in the conduct of its business, including the preparation of
prospectuses, proxy statements and reports required to be filed with federal and
state securities commissions (except insofar as the participation or assistance
of independent accountants and attorneys is, in the opinion of the Investment
Manager, necessary or desirable). In addition, the Investment Manager pays the
salaries of all personnel, including officers of the Fund, who are employees of
the Investment Manager. The Investment Manager also bears the cost of telephone
service, heat, light, power and other utilities provided to the Fund.
 
    Effective December 31, 1993, pursuant to a Services Agreement between
InterCapital and DWSC, DWSC began to provide the administrative services to the
Fund which were previously performed directly by InterCapital. On April 17,
1995, DWSC was reorganized in the State of Delaware, necessitating the entry
into a new Services Agreement by InterCapital and DWSC on that date. The
foregoing internal reorganizations did not result in any change in the nature or
scope of the administrative services being provided to the Fund or any of the
fees being paid by the Fund for the overall services being performed under the
terms of the existing Agreement.
 
   
    Expenses not expressly assumed by the Investment Manager under the Agreement
or by the Distributor of the Fund's shares, Dean Witter Distributors Inc.
("Distributors" or the "Distributor") (see "The Distributor") will be paid by
the Fund. These expenses will be allocated among the four classes of shares of
the Fund (each, a "Class") pro rata based on the net assets of the Fund
attributable to each Class, except as described below. Such expenses include,
but are not limited to: fees pursuant to any plan of distribution (the "12b-1
fee"); (see "The Distributor") charges and expenses of any registrar, custodian,
stock transfer and dividend disbursing agent; brokerage commissions; taxes;
engraving and printing stock certificates; registration costs of the Fund and
its shares under federal and state securities laws; the cost and expense of
printing, including typesetting, and distributing prospectuses and statements of
additional information of the Fund and supplements thereto to the Fund's
shareholders; all expenses of shareholders' and Trustees' meetings and of
preparing, printing and mailing of proxy statements and reports to shareholders;
fees and travel expenses of Trustees or members of any advisory board or
committee who are not employees of the Investment Manager or any corporate
affiliate of the Investment Manager; all expenses incident to any dividend,
withdrawal or redemption
    
 
                                       4
<PAGE>
options; charges and expenses of any outside service used for pricing of the
Fund's shares; fees and expenses of legal counsel, including counsel to the
Trustees who are not interested persons of the Fund or of the Investment Manager
(not including compensation or expenses of attorneys who are employees of the
Investment Manager) and independent accountants; membership dues of industry
associations; interest on Fund borrowings; postage; insurance premiums on
property or personnel (including officers and trustees) of the Fund which inure
to its benefit; extraordinary expenses (including, but not limited to, legal
claims and liabilities and litigation costs and any indemnification relating
thereto); and all other costs of the Fund's operation. The 12b-1 fees relating
to a particular Class will be allocated directly to that Class. In addition,
other expenses associated with a particular Class (except advisory or custodial
fees) may be allocated directly to that Class, provided that such expenses are
reasonably identified as specifically attributable to that Class and the direct
allocation to that Class is approved by the Trustees.
 
   
    As full compensation for the services and facilities furnished to the Fund
and expenses of the Fund assumed by the Investment Manager, the Fund pays the
Investment Manager monthly compensation calculated daily by applying the annual
rate of 0.55% to the Fund's net assets not exceeding $500 million and the annual
rate of 0.525% to the Fund's net assets exceeding $500 million. The management
fee is allocated, among the Classes pro rata based on the net assets of the Fund
attributable to each Class. For the fiscal years ended December 31, 1995, 1996
and 1997, the Fund accrued to the Investment Manager total compensation under
the Agreements in the amounts of $1,179,074, $1,113,792 and $980,937,
respectively.
    
 
    The Agreement provides that in the absence of willful misfeasance, bad
faith, gross negligence or reckless disregard of its obligations thereunder, the
Investment Manager is not liable to the Fund or any of its investors for any act
or omission by the Investment Manager or for any losses sustained by the Fund or
its investors. The Agreement does not restrict the Investment Manager from
acting as investment manager or adviser to others.
 
    The Agreement was initially approved by the Board of Trustees on February
21, 1997 and by the shareholders of the Fund at a Special Meeting of
Shareholders held on May 21, 1997. The Agreement is substantially identical to a
prior investment management agreement which was initially approved by the Board
of Trustees on October 22, 1992 and by the shareholders of the Fund at a Special
Meeting of Shareholders held on January 12, 1993. The Agreement took effect on
May 31, 1997 upon the consummation of the merger of Dean Witter, Discover & Co.
with Morgan Stanley Group Inc. The Agreement may be terminated at any time,
without penalty, on thirty days' notice by the Board of Trustees of the Fund, by
the holders of a majority, as defined in the Investment Company Act of 1940 (the
"Act"), of the outstanding shares of the Fund, or by the Investment Manager. The
Agreement will automatically terminate in the event of its assignment (as
defined in the Act).
 
   
    Under its terms, the Agreement has an initial term ending April 30, 1999 and
provides that it will continue in effect from year to year thereafter, provided
continuance of the Agreement is approved at least annually by the vote of the
holders of a majority, as defined in the Act, of the outstanding shares of the
Fund, or by the Board of Trustees of the Fund; provided that in either event
such continuance is approved annually by the vote of a majority of the Trustees
of the Fund who are not parties to the Agreement or "interested persons" (as
defined in the Act) of any such party, which vote must be cast in person at a
meeting called for the purpose of voting on such approval.

THE BOARD OF TRUSTEES, THE INDEPENDENT TRUSTEES, AND THE COMMITTEES
    
 
   
    The Board of Trustees consists of nine (9) trustees. These same individuals
also serve as directors or trustees for all of the Dean Witter Funds, and are
referred to in this section as Trustees. As of the date of this Statement of
Additional Information, there are a total of 85 Dean Witter Funds, comprised of
129 portfolios. As of February 28, 1998, the Dean Witter Funds had total net
assets of approximately $101 billion and more than six million shareholders.
    
 
   
    Seven Trustees (77% of the total number) have no affiliation or business
connection with InterCapital or any of its affiliated persons and do not own any
stock or other securities issued by Inter-
    
 
                                       8
<PAGE>
   
Capital's parent company, MSDW. These are the "disinterested" or "independent"
Trustees. The other two Trustees (the "management Trustees") are affiliated with
InterCapital. Four of the seven independent Trustees are also Independent
Trustees of the TCW/DW Funds.
    
 
   
    Law and regulation establish both general guidelines and specific duties for
the Independent Trustees. The Dean Witter Funds seek as Independent Trustees
individuals of distinction and experience in business and finance, government
service or academia; these are people whose advice and counsel are in demand by
others and for whom there is often competition. To accept a position on the
Funds' Boards, such individuals may reject other attractive assignments because
the Funds make substantial demands on their time. Indeed, by serving on the
Funds' Boards, certain Trustees who would otherwise be qualified and in demand
to serve on bank boards would be prohibited by law from doing so.
    
 
   
    All of the Independent Trustees serve as members of the Audit Committee and
the Committee of the Independent Trustees. Three of them also serve as members
of the Derivatives Committee. During the calendar year ended December 31, 1997,
the three Committees held a combined total of seventeen meetings. The Committees
hold some meetings at InterCapital's offices and some outside InterCapital.
Management Trustees or officers do not attend these meetings unless they are
invited for purposes of furnishing information or making a report.
    
 
   
    The Committee of the Independent Trustees is charged with recommending to
the full Board approval of management, advisory and administration contracts,
Rule 12b-1 plans and distribution and underwriting agreements; continually
reviewing Fund performance; checking on the pricing of portfolio securities,
brokerage commissions, transfer agent costs and performance, and trading among
Funds in the same complex; and approving fidelity bond and related insurance
coverage and allocations, as well as other matters that arise from time to time.
The Independent Trustees are required to select and nominate individuals to fill
any Independent Trustee vacancy on the Board of any Fund that has a Rule 12b-1
plan of distribution. Most of the Dean Witter Funds have such a plan.
    
 
   
    The Audit Committee is charged with recommending to the full Board the
engagement or discharge of the Fund's independent accountants; directing
investigations into matters within the scope of the independent accountants'
duties, including the power to retain outside specialists; reviewing with the
independent accountants the audit plan and results of the auditing engagement;
approving professional services provided by the independent accountants and
other accounting firms prior to the performance of such services; reviewing the
independence of the independent accountants; considering the range of audit and
non-audit fees; reviewing the adequacy of the Fund's system of internal
controls; and preparing and submitting Committee meeting minutes to the full
Board.
    
 
   
    Finally, the Board of each Fund has formed a Derivatives Committee to
establish parameters for and oversee the activities of the Fund with respect to
derivative investments, if any, made by the Fund.
    
 
   
DUTIES OF CHAIRMAN OF COMMITTEE OF THE INDEPENDENT TRUSTEES AND AUDIT COMMITTEE
    
 
   
    The Chairman of the Committee of the Independent Trustees and the Audit
Committee maintains an office at the Funds' headquarters in New York. He is
responsible for keeping abreast of regulatory and industry developments and the
Funds' operations and management. He screens and/or prepares written materials
and identifies critical issues for the Independent Trustees to consider,
develops agendas for Committee meetings, determines the type and amount of
information that the Committees will need to form a judgment on various issues,
and arranges to have that information furnished to Committee members. He also
arranges for the services of independent experts and consults with them in
advance of meetings to help refine reports and to focus on critical issues.
Members of the Committees believe that the person who serves as Chairman of both
Committees and guides their efforts is pivotal to the effective functioning of
the Committees.
    
 
   
    The Chairman of the Committees also maintains continuous contact with the
Funds' management, with independent counsel to the Independent Trustees and with
the Funds' independent auditors. He arranges for a series of special meetings
involving the annual review of investment advisory, manage-
    
 
                                       9
<PAGE>
   
ment and other operating contracts of the Funds and, on behalf of the
Committees, conducts negotiations with the Investment Manager and other service
providers. In effect, the Chairman of the Committees serves as a combination of
chief executive and support staff of the Independent Trustees.
    
 
   
    The Chairman of the Committee of the Independent Trustees and the Audit
Committee is not employed by any other organization and devotes his time
primarily to the services he performs as Committee Chairman and Independent
Trustee of the Dean Witter Funds and as an Independent Trustee and as Chairman
of the Committee of the Independent Trustees and the Audit Committee of the
    
   
TCW/DW Funds. The current Committee Chairman has had more than 35 years
experience as a senior executive in the investment company industry.
    
 
   
ADVANTAGES OF HAVING SAME INDIVIDUALS AS INDEPENDENT TRUSTEES FOR ALL DEAN
WITTER FUNDS
    
 
   
    The Independent Trustees and the Funds' management believe that having the
same Independent Trustees for each of the Dean Witter Funds avoids the
duplication of effort that would arise from having different groups of
individuals serving as Independent Trustees for each of the Funds or even of
sub-groups of Funds. They believe that having the same individuals serve as
Independent Trustees of all the Funds tends to increase their knowledge and
expertise regarding matters which affect the Fund complex generally and enhances
their ability to negotiate on behalf of each Fund with the Fund's service
providers. This arrangement also precludes the possibility of separate groups of
Independent Trustees arriving at conflicting decisions regarding operations and
management of the Funds and avoids the cost and confusion that would likely
ensue. Finally, having the same Independent Trustees serve on all Fund Boards
enhances the ability of each Fund to obtain, at modest cost to each separate
Fund, the services of Independent Trustees, and a Chairman of their Committees,
of the caliber, experience and business acumen of the individuals who serve as
Independent Trustees of the Dean Witter Funds.
    
 
   
COMPENSATION OF INDEPENDENT TRUSTEES
    
 
   
    The Fund pays each Independent Trustee an annual fee of $800 plus a per
meeting fee of $50 for meetings of the Board of Trustees or committees of the
Board of Trustees attended by the Trustee (the Fund pays the Chairman of the
Audit Committee an annual fee of $750 and pays the Chairman of the Committee of
the Independent Trustees an additional annual fee of $1,200). If a Board meeting
and a Committee meeting, or more than one Committee meeting, take place on a
single day, the Trustees are paid a single meeting fee by the Fund. The Fund
also reimburses such Trustees for travel and other out-of-pocket expenses
incurred by them in connection with attending such meetings. Trustees and
officers of the Fund who are or have been employed by the Investment Manager or
an affiliated company receive no compensation or expense reimbursement from the
Fund.

    As of the date of this Statement of Additional Information, 57 of the Dean
Witter Funds, including the Fund, have adopted a retirement program under which
an Independent Trustee who retires after serving for at least five years (or
such lesser period as may be determined by the Board) as an Independent Director
or Trustee of any Dean Witter Fund that has adopted the retirement program (each
such Fund referred to as an "Adopting Fund" and each such Trustee referred to as
an "Eligible Trustee") is entitled to retirement payments upon reaching the
eligible retirement age (normally, after attaining age 72). Annual payments are
based upon length of service. Currently, upon retirement, each Eligible Trustee
is entitled to receive from the Adopting Fund, commencing as of his or her
retirement date and continuing for the remainder of his or her life, an annual
retirement benefit (the "Regular Benefit") equal to 25.0% of his or her Eligible
Compensation plus 0.4166666% of such Eligible Compensation for each full month
of service as an Independent Director or Trustee of any Adopting Fund in excess
of five years up to a maximum of 50.0% after ten years of service. The foregoing
percentages may be changed by the Board.(1) "Eligible Compensation" is one-fifth
of the total compensation earned by such Eligible Trustee for service to the
Adopting Fund in the five year period prior to the date of the Eligible
Trustee's retirement. Benefits under the retirement program are not secured or
funded by the Adopting Funds.
    
 
   
    The following table illustrates the retirement benefits accrued to the
Fund's Independent Trustees by the Fund for the fiscal year ended December 31,
1997 and by the 57 Dean Witter Funds (including the Fund) for the year ended
December 31, 1997, and the estimated retirement benefits for the Fund's
Independent Trustees, to commence upon their retirement, from the Fund as of
December 31, 1997 and from the 57 Dean Witter Funds as of December 31, 1997.
    
 
- ------------------------
   
(1)  An Eligible Trustee may elect alternate payments of his or her retirement
    benefits based upon the combined life expectancy of such Eligible Trustee
     and his or her spouse on the date of such Eligible Trustee's retirement.
     The amount estimated to be payable under this method, through the remainder
     of the later of the lives of such Eligible Trustee and spouse, will be the
     actuarial equivalent of the Regular Benefit. In addition, the Eligible
     Trustee may elect that the surviving spouse's periodic payment of benefits
     will be equal to either 50% or 100% of the previous periodic amount, an
     election that, respectively, increases or decreases the previous periodic
     amount so that the resulting payments will be the actuarial equivalent of
     the Regular Benefit.

INVESTMENT PRACTICES AND POLICIES
- --------------------------------------------------------------------------------
 
PORTFOLIO SECURITIES
 
    TAXABLE SECURITIES.  As discussed in the Prospectus, the Fund may invest up
to 20% of its total assets in taxable money market instruments, non-New York
tax-exempt securities, futures and options. Investments in taxable money market
instruments would generally be made under any one of the following
circumstances: (a) pending investment of proceeds of sales 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. Only those non-New York tax-exempt securities which satisfy the
standards established for New York tax-exempt securities may be purchased by the
Fund.
 
    In addition, the Fund may temporarily invest more than 20% of its total
assets in non-New York tax-exempt securities and taxable money market
instruments, 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 money market instruments in which the
Fund may invest are limited to the following short-term fixed-income securities
(maturing in one year or less from the time of purchase): (i) obligations of the
United States Government, its agencies, instrumentalities or authorities; (ii)
commercial paper rated P-1 by Moody's Investors Service, Inc. ("Moody's") or A-1
by Standard & Poor's Corporation ("S&P"); (iii) certificates of deposit of
domestic banks with assets of $1 billion or more; and (iv) repurchase agreements
with respect to portfolio securities.
 
    TAX-EXEMPT SECURITIES.  As discussed in the Prospectus, at least 80% of the
Fund's total assets will be invested in New York tax-exempt securities (New York
Municipal Bonds, New York Municipal Notes and New York Municipal Commercial
Paper). In regard to the Moody's and S&P ratings discussed in the Prospectus, it
should be noted that the ratings represent the organizations' opinions as to the
quality of the securities which they undertake to rate and that the ratings are
general and not absolute standards of quality. For a description of Municipal
Bond, Municipal Note and Municipal Commercial Paper ratings by Moody's and S&P,
see the Appendix to this Statement of Additional Information.
 
    The Fund does not have any minimum quality rating standard for its
downgraded investments. As such, the Fund may hold securities rated as low as
Caa, Ca or C by Moody's or CCC, CC, C or CI by S&P.
 
                                       12
<PAGE>
Bonds rated Caa or Ca by Moody's may already be in default on payment of
interest or principal, while bonds rated C by Moody's, their lowest bond rating,
can be regarded as having extremely poor prospects of ever attaining any real
investment standing. Bonds rated CI by S&P, their lowest bond rating, are no
longer making interest payments.
 
    The payment of principal and interest by issuers of certain Municipal
Obligations purchased by the Fund may be guaranteed by letters of credit or
other credit facilities offered by banks or other financial institutions. Such
guarantees will be considered in determining whether a Municipal Obligation
meets the Fund's investment quality requirements. In addition, some issues may
contain provisions which permit the Fund to demand from the issuer repayment of
principal at some specified period(s) prior to maturity.
 
    MUNICIPAL BONDS.  Municipal Bonds, as referred to in the Prospectus, are
debt obligations of a United States territory or possession, state, its cities,
municipalities and municipal agencies (all of which are generally referred to as
"municipalities") which generally have a maturity at the time of issuance of one
year or more, and the interest from which is, in the opinion of bond counsel,
exempt from federal income tax. In addition to these requirements, the interest
from New York Municipal Bonds must be, in the opinion of bond counsel, exempt
from New York personal income tax. They are issued to raise funds for various
public purposes, such as construction of a wide range of public facilities, to
refund outstanding obligations and to obtain funds for general operating
expenses or to loan to other public institutions and facilities. In addition,
certain types of industrial development bonds and pollution control bonds are
issued by or on behalf of public authorities to provide funding for various
privately operated facilities.
 
    MUNICIPAL NOTES.  Municipal Notes are short-term obligations of
municipalities, generally with a maturity at the time of issuance ranging from
six months to three years, the interest from which is, in the opinion of bond
counsel, exempt from federal income tax. In addition to those requirements, the
interest from New York Municipal Notes must be, in the opinion of bond counsel,
exempt from New York personal income tax. The principal types of Municipal Notes
include tax anticipation notes, bond anticipation notes, revenue anticipation
notes and project notes, although there are other types of Municipal Notes in
which the Fund may invest. Notes sold in anticipation of collection of taxes, a
bond sale or receipt of other revenues are usually general obligations of the
issuing municipality or agency.
 
    MUNICIPAL COMMERCIAL PAPER.  Municipal Commercial Paper refers to short-term
obligations of municipalities the interest from which is, in the opinion of bond
counsel, exempt from federal income tax. In addition to those requirements, the
interest from New York Commercial Paper must be, in the opinion of bond counsel,
exempt from New York personal income tax. They may be issued at a discount and
are sometimes referred to as Short-Term Discount Notes. Municipal Commercial
Paper is likely to be used to meet seasonal working capital needs of a
municipality or interim construction financing and to be paid from general
revenues of the municipality or refinanced with long-term debt. In most cases
Municipal Commercial Paper is backed by letters of credit, lending agreements,
note repurchase agreements or other credit facility agreements offered by banks
or other institutions.
 
    Issuers of these obligations are subject to the provisions of bankruptcy,
insolvency and other laws affecting the rights and remedies of creditors, such
as the Federal Bankruptcy Act, and laws, if any, which may be enacted by
Congress or any state extending the time for payment of principal or interest,
or both, or imposing other constraints upon enforcement of such obligations or
upon municipalities to levy taxes. There is also the possibility that as a
result of litigation or other conditions the power or ability of any one or more
issuers to pay, when due, principal of and interest on its, or their, Municipal
Bonds, Municipal Notes and Municipal Commercial Paper may be materially
affected.
 
RISK CONSIDERATIONS
 
    Because of the special nature of securities which are rated below investment
grade by national credit rating agencies ("lower-rated securities"), the
Investment Manager must take into account certain special considerations in
assessing the risks associated with such investments. For example, as the
lower-rated securities market is relatively new, its growth has paralleled a
long economic expansion and it has not weathered a recession in its present size
and form. Therefore, an economic downturn or
 
                                       13
<PAGE>
increase in interest rates is likely to have a negative effect on this market
and on the value of the lower-rated securities held by the Fund, as well as on
the ability of the securities' issuers to repay principal and interest on their
borrowings.
 
    The prices of lower-rated securities have been found to be less sensitive to
changes in prevailing interest rates than higher-rated investments, but are
likely to be more sensitive to adverse economic changes or individual
issuer/debtor developments. During an economic downturn or substantial period of
rising interest rates, highly leveraged issuers may experience financial stress
which would adversely affect their ability to service their principal and
interest payment obligations, to meet their projected business goals or to
obtain additional financing. If the issuer of a fixed-income security owned by
the Fund defaults, the Fund may incur additional expenses to seek recovery. In
addition, periods of economic uncertainty and change can be expected to result
in an increased volatility of market prices of lower rated securities and a
concomitant volatility in the net asset value of a share of the Fund. Moreover,
the market prices of certain of the Fund's portfolio securities which are
structured as zero coupon securities are affected to a greater extent by
interest rate changes and thereby tend to be more volatile than securities which
pay interest periodically and in cash (see "Dividends, Distributions and Taxes"
for a discussion of the tax ramifications of investments in such securities).
 
    The secondary market for lower-rated securities may be less liquid than the
markets for higher quality securities and, as such, may have an adverse effect
on the market prices of certain securities. The limited liquidity of the market
may also adversely affect the ability of the Fund's Trustees to arrive at a fair
value for certain lower-rated securities at certain times and should make it
difficult for the Fund to sell certain securities.
 
    New laws and proposed new laws may have a potentially negative impact on the
market for lower-rated securities. For example, recent legislation requires
federally-insured savings and loan associations to divest their investments in
lower-rated securities. This legislation and other proposed legislation may have
an adverse effect upon the value of lower-rated securities and a concomitant
negative impact upon the net asset value of a share of the Fund.
 
    VARIABLE RATE OBLIGATIONS.  As stated in the Prospectus, the Fund may invest
in obligations of the type 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. Other features may include the
right whereby the Fund may demand prepayment of the principal amount of the
obligation prior to its stated maturity (a "demand feature") and the right of
the issuer to prepay the principal amount prior to maturity. The principal
benefit of a variable rate obligation is that the interest rate adjustment
minimizes changes in the market value of the obligation. The principal benefit
to the Fund of purchasing obligations with a demand feature is that liquidity,
and the ability of the Fund to obtain repayment of the full principal amount of
the obligation prior to maturity, is enhanced.
 
   
    LENDING OF PORTFOLIO SECURITIES.  The Fund may lend portfolio securities to
brokers, dealers and financial institutions provided that cash equal to at least
100%, of the market value of the securities loaned is deposited by the borrower
with the Fund and is maintained each business day in a segregated account
pursuant to applicable regulations. While such securities are on loan, the
borrower will pay the Fund any income accruing thereon, and the Fund may invest
the cash collateral in portfolio securities, thereby earning additional income.
The Fund will not lend its portfolio securities if such loans are not permitted
by the laws or regulations of any state in which its shares are qualified for
sale and will not lend more than 25% of the value of its total assets. Loans
will be subject to termination by the Fund in the normal settlement time,
currently five business days after notice, or by the borrower on one day's
notice. Borrowed securities must be returned when the loan is terminated. Any
gain or loss in the market price of the borrowed securities which occurs during
the term of the loan inures to the Fund and its shareholders. The Fund may pay
reasonable finders, borrowers, administrative, and custodial fees in connection
with a loan. The creditworthiness of firms to which the Fund lends its portfolio
securities will be monitored on an ongoing basis. During the fiscal year ended
December 31, 1997, the Fund did not loan its portfolio securities and it has no
current intention to loan its portfolio securities in the foreseeable future.
    
 
                                       14
<PAGE>
   
    WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS.  As
discussed in the Prospectus, from time to time, in the ordinary course of
business, the Fund may purchase securities on a when-issued or delayed delivery
basis and may purchase or sell securities on a forward commitment basis. When
such transactions are negotiated, the price is fixed at the time of the
commitment, but delivery and payment can take place a month or more after the
date of the commitment. The securities so purchased are subject to market
fluctuation and no interest accrues to the purchaser during this period. While
the Fund will only purchase securities on a when-issued, delayed delivery or
forward commitment basis with the intention of acquiring the securities, the
Fund may sell the securities before the settlement date, if it is deemed
advisable. At the time the Fund makes the commitment to purchase securities on a
when-issued or delayed delivery basis, the Fund will record the transaction and
thereafter reflect the value, each day, of such security in determining the net
asset value of the Fund. At the time of delivery of the securities, the value
may be more or less than the purchase price. The Fund will also establish a
segregated account with the Fund's custodian bank in which it will continuously
maintain cash or U.S. Government securities or other liquid portfolio securities
equal in value to commitments for such when-issued or delayed delivery
securities; subject to this requirement, the Fund may purchase securities on
such basis without limit. 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.
    
 
HEDGING ACTIVITIES
 
    The Fund may enter financial futures contracts, options on such futures and
municipal bond index futures contracts for hedging purposes.
 
FUTURES CONTRACTS AND OPTIONS ON FUTURES
 
    As discussed in the Prospectus, the Fund may invest in financial futures
contracts ("futures contracts") and related options thereon. These futures
contracts and related options thereon will be used only as a hedge against
anticipated interest rate changes. A futures contract sale creates an obligation
by the Fund, as seller, to deliver the specific type of instrument called for in
the contract at a specified future time for a specified price. A futures
contract purchase would create an obligation by the Fund, as purchaser, to take
delivery of the specific type of financial instrument at a specified future time
at a specified price. The specific securities delivered or taken, respectively,
at settlement date, would not be determined until or near that date. The
determination would be in accordance with the rules of the exchange on which the
futures contract sale or purchase was effected.
 
    Although the terms of futures contracts specify actual delivery or receipt
of securities, in most instances the contracts are closed out before the
settlement date without the making or taking of delivery of the securities.
Closing out of a futures contract is usually effected by entering into an
offsetting transaction. An offsetting transaction for a futures contract sale is
effected by the Fund entering into a futures contract purchase for the same
aggregate amount of the specific type of financial instrument at the same
delivery date. If the price in the sale exceeds the price in the offsetting
purchase, the Fund is immediately paid the difference and thus realizes a gain.
If the offsetting purchase price exceeds the sale price, the Fund pays the
difference and realizes the loss. Similarly, the closing out of a futures
contract purchase is effected by the Fund entering into a futures contract sale.
If the offsetting sale price exceeds the purchase price the Fund realizes a
gain, and if the offsetting sale price is less than the purchase price the Fund
realizes a loss.
 
    Unlike a futures contract, which requires the parties to buy and sell a
security on a set date, an option on a futures contract entitles its holder to
decide on or before a future date whether to enter into such a contract. If the
holder decides not to enter into the contract, the premium paid for the option
is lost. Since the value of the option is fixed at the point of sale, there are
no daily payments of cash to reflect the change in the value of the underlying
contract, as discussed below for futures contracts. The value of the option
changes and is reflected in the net asset value of the Fund.
 
    The Fund is required to maintain margin deposits with brokerage firms
through which it effects futures contracts and options thereon. The initial
margin requirements vary according to the type of the
 
                                       15
<PAGE>
underlying security. In addition, due to current industry practice daily
variations in gains and losses on open contracts are required to be reflected in
cash in the form of variation margin payments. The Fund may be required to make
additional margin payments during the term of the contract.
 
    Currently, futures contracts can be purchased on debt securities such as
U.S. Treasury Bills and Bonds, U.S. Treasury Notes with maturities between 6 1/2
and 10 years, Certificates of the Government National Mortgage Association and
Bank Certificates of Deposit. The Fund may invest in interest rate futures
contracts covering these types of financial instruments as well as in new types
of contracts that become available in the future.
 
    Financial futures contracts are traded in an auction environment on the
floors of several Exchanges--principally the Chicago Board of Trade, the Chicago
Mercantile Exchange and the New York Futures Exchange. Each exchange guarantees
performance under contract provisions through a clearing corporation, a
nonprofit organization managed by the exchange membership which is also
responsible for handling daily accounting of deposits or withdrawals of margin.
 
    A risk in employing futures contracts 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 correlation may be distorted by the fact
that the futures market is dominated by short-term traders seeking to profit
from the difference between a contract or security price objective and their
cost of borrowed funds. This would reduce their value for hedging purposes over
a short time period. The correlation may be further distorted since the futures
contracts that are being used to hedge are not based on municipal obligations.
 
    Another risk is that 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.
 
    Put and call options on financial futures have similar characteristics as
exchange-traded options. See below for a further description of options.
 
    In addition to the risks associated with investing in options on securities,
there are particular risks associated with investing in options on futures. In
particular, the ability to establish and close out positions on such options
will be subject to the development and maintenance of a liquid secondary market.
It is not certain that this market will develop.
 
    In order to assure that the Fund is entering into transactions in futures
contracts for hedging purposes as such is defined by the Commodity Futures
Trading Commission either: 1) a substantial majority (i.e., approximately 75%)
of all anticipatory hedge transactions (transactions in which the Fund does not
own at the time of the transaction, but expects to acquire, the securities
underlying the relevant futures contract) involving the purchase of futures
contracts will be completed by the purchase of securities which are the subject
of the hedge or 2) the underlying value of all long positions in futures
contracts will not exceed the total value of a) all short-term debt obligations
held by the Fund; b) cash held by the Fund; c) cash proceeds due to the Fund on
investments within thirty days; d) the margin deposited on the contracts; and e)
any unrealized appreciation in the value of the contracts.
 
    The Fund may not enter into futures contracts or related options thereon if
immediately thereafter the amount committed to margin plus the amount paid for
option premiums exceeds 5% of the value of the Fund's total assets. In instances
involving the purchase of futures contracts by the Fund, the market value of the
futures contract will be deposited in a segregated account of cash and cash
equivalents to collateralize the position and thereby ensure that the use of
such futures is unleveraged. The Fund may not purchase or sell futures contacts
or related options if immediately thereafter more than one-third of its net
assets would be hedged.
 
                                       16
<PAGE>
    MUNICIPAL BOND INDEX FUTURES.  The Fund may utilize municipal bond index
futures contracts 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.
 
    OPTIONS.  The Fund may purchase or sell (write) options on debt securities
as a means of achieving additional return or hedging the value of the Fund's
portfolio. The Fund would only buy options listed on national securities
exchanges. The Fund will not purchase options if, as a result, the aggregate
cost of all outstanding options exceeds 10% of the Fund's total assets.
 
    Presently there are no options on New York tax-exempt securities traded on
national securities exchanges and until such time as they become available, the
Fund will not invest in options on debt securities. It is anticipated that such
instruments will not become available during the next year.
 
    A call option is a contract that gives the holder of the option the right to
buy from the writer of the call option, in return for a premium, the security
underlying the option at a specified exercise price at any time during the term
of the option. The writer of the call option has the obligation upon exercise of
the option to deliver the underlying security upon payment of the exercise price
during the option period. A put option is a contract that gives the holder of
the option the right to sell to the writer, in return for a premium, the
underlying security at a specified price during the term of the option. The
writer of the put has the obligation to buy the underlying security upon
exercise, at the exercise price during the option period.
 
    The Fund will only write covered call or covered put options. The Fund may
not write covered options in an amount exceeding 20% of the value of its total
assets. A call option is "covered" if the Fund owns the underlying security
subject to the option or has an absolute and immediate right to acquire that
security or futures contract without additional cash consideration (or for
additional cash consideration held in a segregated account by its custodian)
upon conversion or exchange of other securities held in its portfolio. A call
option is also covered if the Fund holds a call on the same security or futures
contract as the call written where the exercise price of the call held is (i)
equal to or less than the exercise price of the call written or (ii) greater
than the exercise price of the call written if the difference is maintained by
the Fund in cash, Treasury bills or other liquid portfolio securities in a
segregated account with its custodian. A put option is "covered" if the Fund
maintains cash, Treasury bills or other liquid portfolio securities with a value
equal to the exercise price in a segregated account with its custodian, or else
holds a put on the same security or futures contract as the put written where
the exercise price of the put held is equal to or greater than the exercise
price of the put written.
 
    If the Fund has written an option, it may terminate its obligation by
effecting a closing purchase transaction. This is accomplished by purchasing an
option of the same series as the option previously written. However, once the
Fund has been assigned an exercise notice, the Fund will be unable to effect a
closing purchase transaction. Similarly, if the Fund is the holder of an option
it may liquidate its position by effecting a closing sale transaction. This is
accomplished by selling an option of the same series as the option previously
purchased. There can be no assurance that either a closing purchase or sale
transaction can be effected when the Fund so desires.
 
    The Fund will realize a profit from a closing transaction if the price of
the transaction is less than the premium received from writing the option or is
more than the premium paid to purchase the option; the Fund will realize a loss
from a closing transaction if the price of the transaction is more than the
premium received from writing the option or is less than the premium paid to
purchase the option. Since call option prices generally reflect increases in the
price of the underlying security, any loss resulting from the repurchase of a
call option may also be wholly or partially offset by unrealized appreciation of
the
 
                                       17
<PAGE>
underlying security. Other principal factors affecting the market value of a put
or a call option include supply and demand, interest rates, the current market
price and price volatility of the underlying security and the time remaining
until the expiration date.
 
    An option position may be closed out only on an exchange which provides a
secondary market for an option of the same series. Although the Fund will
generally purchase or write only those options for which there appears to be an
active secondary market, there is no assurance that a liquid secondary market on
an exchange will exist for any particular option. In such event it might not be
possible to effect closing transactions in particular options, so that the Fund
would have to exercise its options in order to realize any profit and would
incur brokerage commissions upon the exercise of call options and upon the
subsequent disposition of underlying securities for the exercise of put options.
If the Fund, as a covered call option writer, is unable to effect a closing
purchase transaction in a secondary market, it will not be able to sell the
underlying security until the option expires or it delivers the underlying
security upon exercise.
 
   
SPECIAL CONSIDERATIONS RELATING TO NEW YORK TAX-EXEMPT SECURITIES
    
 
    During the mid-1970's, New York State (the "State"), some of its agencies,
instrumentalities and public benefit corporations (the "Authorities"), and
certain of its municipalities faced serious financial difficulties. To address
many of these financial problems, the State developed various programs, many of
which were successful in ameliorating the financial crisis. Any further
financial problems experienced by these Authorities or municipalities could have
a direct adverse effect on the New York Municipal Obligations in which the Fund
invests.
 
NEW YORK CITY
 
   
    GENERAL.  The national economic downturn which began in July 1990 adversely
affected the local economy, which had been declining since late 1989. As a
result, New York City (the "City") experienced job losses in 1990 and 1991 and
real Gross City Product (GCP) fell in those two years. For the 1992 fiscal year,
the City closed a projected budget gap of $3.3 billion in order to achieve a
balanced budget as required by the laws of the State. Beginning in 1992, the
improvement in the national economy helped stabilize conditions in the City.
Employment losses moderated toward year-end and real GCP increased, boosted by
strong wage gains. After noticeable improvements in the City's economy during
calendar year 1994, economic growth slowed in 1995 and thereafter improved
commencing in calendar year 1996, reflecting improved securities industry
earnings and employment in other sectors. The City's current four-year financial
plan assumes that moderate economic growth will exist through calendar year
2001, with moderate job growth and wage increases.
    
 
   
    For each of the 1981 through 1996 fiscal years, the City achieved balanced
operating results as reported in accordance with then applicable generally
accepted accounting principles ("GAAP"). The City has been required to close
substantial gaps between forecast revenues and forecast expenditures in order to
maintain balanced operating results. There can be no assurance that the City
will continue to maintain balanced operating results as required by State law
without additional tax or other revenue increases or additional reductions in
City services or entitlement programs, which could adversely affect the City's
economic base.
    
 
   
    1998-2001 NEW YORK CITY FINANCIAL PLAN.  The Mayor is responsible for
preparing the City's four-year financial plan including the current financial
plan for the 1998 through 2001 fiscal years (the "1998-2001 Financial Plan," the
"Financial Plan" or "City Plan"). The most recent quarterly modification to the
City's financial plan for the 1997 fiscal year projects a balanced budget in
accordance with GAAP for the 1997 fiscal year, after taking into account an
increase in projected tax revenues of $1.2 billion during the 1997 fiscal year
and a discretionary prepayment in the 1997 fiscal year of $1.3 billion of debt
service due in the 1998 and 1999 fiscal years. The Financial Plan projects
revenues and expenditures for the 1998 fiscal year balanced in accordance with
GAAP. The Financial Plan includes: increased tax revenue projections; reduced
debt service costs; the assumed restoration of Federal funding for programs
assisting certain legal aliens; additional expenditure for textbooks, computers,
improved education programs and welfare reform, law enforcement, immigrant
naturalization, initiatives proposed by the City Council and other initiatives;
and a proposed discretionary transfer to the 1998 fiscal year of
    
 
                                       18
<PAGE>
   
$300 million of debt service due in the 1999 fiscal year for budget
stabilization purposes. In addition, the Financial Plan reflects the
discretionary transfer to the 1997 fiscal year of $1.3 billion of debt service
due in the 1998 and 1999 fiscal years, and includes actions to eliminate a
previously projected budget gap for the 1998 fiscal year. These gap closing
actions include (i) additional agency actions totaling $621 million; (ii) the
proposed sale of various assets; (iii) additional State aid of $294 million,
including a proposal that the State accelerate a $142 million revenue sharing
payment to the City from March 1999; and (iv) entitlement savings of $128
million which would result from certain of the reductions in Medicaid spending
proposed in the Governor's 1997-1998 Executive Budget and the State making
available to the City $77 million of additional Federal block grant aid, as
proposed in the Governor's 1997-1998 Executive Budget. The Financial Plan also
sets forth projections for the 1999 through 2001 fiscal years and projects gaps
of $1.8 billion, $2.8 billion and $2.6 billion for the 1999 through 2001 fiscal
years, respectively.
    
 
   
    The Financial Plan assumes approval by the State Legislature and the
Governor of a tax reduction program proposed by the City and a proposed State
tax relief program. The Financial Plan also assumes (i) approval by the governor
and the State Legislature of the extension of the 14% personal income tax
surcharge, which is scheduled to expire on December 31, 1999, and of the
extension of the 12.5% personal income tax surcharge, which is scheduled to
expire on December 31, 1998; (ii) collection of the projected rent payments for
the City's airports; and (iii) State approval of the cost containment
initiatives and State aid proposed by the City for the 1998 fiscal year, and
$115 million in State aid which is assumed in the Financial Plan but was not
provided for in the Governor's 1997-1998 Executive budget. The Financial Plan
reflects the increased costs which the City is prepared to incur as a result of
welfare legislation recently enacted by Congress. In addition, the economic and
financial condition of the City may be affected by various financial, social,
economic and political factors which could have a material effect on the City.
    
 
   
    The City's financial plans have been the subject of extensive public
comment. On September 11, 1997, the New York State Comptroller issued a report
which noted that the ability to deal with future budget gaps could become a
significant issue in the State's 2000-2001 fiscal year, when the cost of tax
cuts increases by $1.9 billion. The report contained projections that, based on
current economic conditions and current law for taxes and spending, showed a gap
of $5.6 billion in the 2000-2001 State fiscal year and of $7.4 billion in the
2001-2002 State fiscal year. The report noted that these gaps would be smaller
if recurring spending reductions produce savings in earlier years. The State
Comptroller also stated that if Wall Street earnings moderate and the State
experiences a moderate recession, the gap for the 2001-2002 State fiscal year
could grow to nearly $12 billion.
    
 
   
    The City depends on the State for aid both to enable the City to balance its
budget and to meet its cash requirements. There can be no assurance that there
will not be reductions in State aid to the City from amounts currently
projected; that the State budgets will be adopted by the April 1 statutory
deadline or interim appropriations enacted; or that any such reductions or
delays will not have adverse effects on the City's cash flow or expenditures.
    
 
   
    The City's projections set forth in the City Plan are based on various
assumptions and contingencies which are uncertain and which may not materialize.
Changes in major assumptions could significantly affect the City's ability to
balance its budget as required by State law and to meet its annual cash flow and
financing requirements. Such assumptions and contingencies include: the
condition of the regional and local economies, the impact on real estate tax
revenues of the real estate market, wage increases for City employees consistent
with those assumed in the Financial Plan, employment growth, the ability to
implement proposed reductions in City personnel and other cost reduction
initiatives, the ability of the New York City Health and Hospitals Corporations
and the Board of Education to take actions to offset potential budget
shortfalls, the ability to complete revenue generating transactions, provision
of State and Federal aid and mandate relief and the impact on City revenues and
expenditures of Federal and State welfare reform and any future legislation
affecting Medicare or other entitlement.
    
 
                                       19
<PAGE>
   
    Implementation of the Financial Plan is also dependent upon the City's
ability to market its securities successfully. The City's financing program for
fiscal years 1998 through 2001 contemplates the issuance of $4.9 billion of
general obligation bonds and $7.1 billion of bonds to be issued by the New York
City Transitional Finance Authority (the "Finance Authority") to finance City
capital projects. The Finance Authority was created as part of the City's effort
to assist in keeping the City's indebtedness within the forecast level of the
constitutional restrictions on the amount of debt the City is authorized to
incur. In addition, the City issues revenue and tax anticipation notes to
finance its seasonal working capital requirements. The success of projected
public sales of City bonds and notes, New York City Municipal Water Finance
Authority ("Water Authority") bonds and Finance Authority bonds will be subject
to prevailing market conditions. The City's planned capital and operating
expenditures are dependent upon the sale of its general obligation bonds and
notes, and the Water Authority and Finance Authority bonds. Future developments
concerning the City and public discussion of such developments, as well as
prevailing market conditions, may affect the market for outstanding City general
obligation bonds and notes.
    
 
   
    The City Comptroller and other agencies and public officials have issued
reports and made public statements which, among other things, state that
projected revenues and expenditures may be different from those forecasted in
the City Plan. It is reasonable to expect that such reports and statements will
continue to be issued and to engender public comment.
    
 
   
    RATINGS.  On July 10, 1995, Standard & Poor's revised downward its rating on
City general obligation bonds from A- to BBB+ and removed City bonds from
CreditWatch. Fitch Investors Service, Inc. ("Fitch") continues to rate the City
general obligation bonds A-. On February 28, 1996, Fitch placed the City's
general obligation bonds on FitchAlert with negative implications. Moody's
rating for City general obligation bonds is Baa1. On July 17, 1997, Moody's
changed its outlook on City bonds to positive from stable. Such ratings reflect
only the views of these rating agencies, from which an explanation of the
significance of such ratings may be obtained. There is no assurance that such
ratings will continue for any given period of time or that they will not be
revised downward or withdrawn entirely. Any such downward revision or withdrawal
could have an adverse effect on the market prices of bonds.
    
 
   
    OUTSTANDING INDEBTEDNESS.  As of September 30, 1997, the City and the
Municipal Assistance Corporation for the City of New York had, respectively,
approximately $26.180 billion and $3.717 billion of outstanding net long-term
debt.
    
 
    LITIGATION.  The City is a defendant in lawsuits pertaining to material
matters, including claims asserted which are incidental to performing routine
governmental and other functions. This litigation includes, but is not limited
to, actions commenced and claims asserted against the City arising out of
alleged torts, alleged breaches of contracts, alleged violations of law and
condemnation proceedings. As of June 30, 1996 and 1995, claims in excess of $380
billion and $311 billion, respectively, were outstanding against the City for
which the City estimates its potential future liability to be $2.8 billion and
$2.5 billion, respectively.
 
NEW YORK STATE
 
   
    RECENT DEVELOPMENTS.  The national economy has resumed a more robust rate of
growth after a "soft landing" in 1995, with over 14 million jobs added
nationally since early 1992. The State economy has continued to expand, but
growth remains somewhat slower than in the nation. Although the State has added
approximately 300,000 jobs since late 1992, employment growth in the State has
been hindered during recent years by significant cutbacks in the computer and
instrument manufacturing, utility, defense and banking industries. Government
downsizing has also moderated these job gains.
    
 
   
    The 1997-1998 New York State Financial Plan (the "State Plan") is partly
based on the forecast that the State's economy shows moderate expansion during
the first half of calendar 1997 with the trend continuing through the year.
Although industries that export goods and services are expected to continue to
do well, growth is expected to be moderated by tight fiscal constraints on the
health care and
    
 
                                       20
<PAGE>
   
social services industries. On an average annual basis, employment growth in the
State is expected to be up substantially from the 1996 rate. Personal income is
expected to record moderate gains in 1997. Bonus payments in the securities
industry are expected to increase further from last year's record level.
    
 
    The State Plan is based upon forecasts of national and State economic
activity developed through both internal analysis and review of State and
national economic forecasts prepared by commercial forecasting services and
other public and private forecasters. Economic forecasts have frequently failed
to predict accurately the timing and magnitude of changes in the national and
the State economies. Many uncertainties exist in forecasts of both the national
and State economies, including consumer attitudes toward spending, the extent of
corporate and governmental restructuring, federal fiscal and monetary policies,
the level of interest rates, and the condition of the world economy, which could
have an adverse effect on the State. There can be no assurance that the State
economy will not experience results in the current fiscal year that are worse
than predicted, with corresponding material and adverse effects on the State's
projections of receipts and disbursements.
 
   
    THE 1997-98 FISCAL YEAR.  The State's General Fund (the major operating fund
of the State) was projected in the State Plan to be balanced on a cash basis for
the 1997-98 fiscal year. Total receipts and transfers from other funds are
projected at $35.09 billion, an increase of $2.05 billion from the prior fiscal
year, and disbursements and transfers to other funds are projected to be $34.60
billion, an increase of $1.70 billion from the total disbursed in the prior
fiscal year.
    
 
    NEW YORK LOCAL GOVERNMENT ASSISTANCE CORPORATION.  In 1990, as part of a
state fiscal reform program, legislation was enacted creating the New York Loan
Government Assistance Corporation ("LGAC"), a public benefit corporation
empowered to issue long-term obligations to fund certain payments to local
governments traditionally funded through the State's annual seasonal borrowing.
The legislation empowered LGAC to issue bonds and notes in an amount not in
excess of $4.7 billion (exclusive of certain refunding bonds) plus certain other
amounts. Over a period of years, the issuance of those long-term obligations,
which will be amortized over no more than 30 years, is expected to result in
eliminating the need for continuing short-term seasonal borrowing for those
purposes. The legislation also imposed a cap on the annual seasonal borrowing of
the State at $4.7 billion, less net proceeds of bonds issued by LGAC, except in
cases where the Governor and the legislative leaders have certified both the
need for additional borrowing and provided a schedule for reducing it to the
cap. If borrowing above the cap is thus permitted in any fiscal year, it is
required by law to be reduced to the cap by the fourth fiscal year after the
limit was first exceeded.
 
   
    As of June 30, 1995, LGAC issued bonds and notes to provide net proceeds of
$4.7 billion, completing the program. The impact of this borrowing, together
with the availability of certain cash reserves is that the State is able to meet
its cash flow needs throughout the fiscal year without relying on short-term
seasonal borrowings.
    
 
    COMPOSITION OF STATE GOVERNMENTAL FUNDS GROUP.  Substantially all State
non-pension financial operations are accounted for in the State's governmental
funds group. Governmental funds include: (i) the General Fund, which receives
all income not required by law to be deposited in another fund; (ii) Special
Revenue Funds, which receive the preponderance of moneys received by the State
from the Federal government and other income, the use of which is legally
restricted to certain purposes; (iii) Capital Projects Funds, used to finance
the acquisition, construction and rehabilitation of major capital facilities by
the State and to aid in certain of such projects conducted by local governments
or public authorities; and (iv) Debt Service Funds, which are used for the
accumulation of moneys for the payment of principal of and interest on long-term
debt and to meet lease-purchase and other contractual-obligation commitments.
 
    AUTHORITIES.  The fiscal stability of the State is related to the fiscal
stability of its public authorities (i.e. public benefit corporations, created
pursuant to State law, other than local authorities), which generally have
responsibility for financing, constructing and operating revenue-producing
public benefit facilities. The State's public authorities (the "Authorities")
are not subject to the constitutional restrictions on the incurrence of debt
which apply to the State itself, and may issue bonds and notes within the
amounts of,
 
                                       21
<PAGE>
   
and as otherwise restricted by, their legislative authorization. As of September
30, 1996, there were 17 Authorities that had outstanding debt of $100 million or
more and the aggregate outstanding debt, including refunding bonds, of these 17
Authorities was $75.4 billion, only a portion of which constitutes
State-supported or State-related debt.
    
 
    Authorities are generally supported by revenues generated by the projects
financed or operated, such as fares, user fees on bridges or tunnels, highway
tolls and rentals for dormitory rooms and housing units and charges for
occupancy at medical care facilities. In addition, State legislation authorizes
several financing techniques for Authorities. Also, there are statutory
arrangements providing for State local assistance payments otherwise payable to
localities to be made under certain circumstances to Authorities. Although the
State has no obligation to provide additional assistance to localities whose
local assistance payments have been paid to Authorities under these
arrangements, if local assistance payments are diverted the affected localities
could seek additional State assistance. Some Authorities also receive moneys
from State appropriations to pay for the operating costs of certain of their
programs.
 
   
    RATINGS.  On January 13, 1992, Standard & Poor's reduced its ratings on the
State's general obligation bonds from A to A- and, in addition, reduced its
ratings on the State's moral obligation, lease purchase, guaranteed and
contractual obligation debt. Standard & Poor's also continued its negative
rating outlook assessment on State general obligation debt. On April 26, 1993,
Standard & Poor's revised the rating outlook assessment to stable. On February
14, 1994, Standard & Poor's raised is outlook to positive and, on August 5,
1996, confirmed its A- rating. On August 28, 1997, Standard & Poor's revised its
ratings on the State's general obligation bonds from A- to A and, in addition,
revised its ratings on the State's moral obligation, lease purchase, guaranteed
and contractual obligation debt. On January 6, 1992, Moody's Investors Service
reduced its ratings on outstanding limited-liability State lease purchase and
contractual obligations from A to Baa1. On July 26, 1996, Moody's Investors
Service reconfirmed its A rating on the State's general obligation long-term
indebtedness. On February 10, 1997, Moody's confirmed its A2 rating on the
State's general obligation long-term indebtedness. Ratings reflect only the
respective views of such organizations, and an explanation of the significance
of such ratings must be obtained from the rating agency furnishing the same.
There is no assurance that a particular rating will continue for any given
period of time or that any such rating will not be revised downward or withdrawn
entirely if, in the judgment of the agency originally establishing the rating,
circumstances so warrant. A downward revision or withdrawal of such ratings, or
either of them, may have an effect on the market price of the State Municipal
Securities in which the New York Fund invests.
    
 
   
    GENERAL OBLIGATION DEBT.  As of March 31, 1997, the State had outstanding
approximately $5.03 billion in general obligation bonds, including $294 million
in bond anticipation notes outstanding. Principal and interest due on general
obligation bonds and interest due on bond anticipation notes were $749.6 million
for the 1996-97 fiscal years, and are estimated to be $720.9 million for the
State's 1997-98 fiscal year.
    
 
   
    LITIGATION.  The State is a defendant in numerous legal proceedings
pertaining to matters incidental to the performance of routine governmental
operations. Such litigation includes, but is not limited to, claims asserted
against the State arising from alleged torts, alleged breaches of contracts,
condemnation proceedings and other alleged violations of State and Federal laws.
These proceedings could affect adversely the financial condition of the State in
the 1997-1998 Fiscal Year or thereafter.
    
 
   
    The State believes that the 1997-1998 State Financial Plan includes
sufficient reserves for the payment of judgments that may be required during the
1996-1997 fiscal year. There can be no assurance, however, that an adverse
decision in any of these proceedings would not exceed the amount of all
potential State Plan reserves available for the payment of judgements and,
therefore, could affect the ability of the State to maintain a balanced
1997-1998 State Plan. The General Purpose Financial Statements for the 1996-1997
fiscal year report estimated probable awarded and anticipated unfavorable
judgements of $364 million, of which $134 million is expected to be paid during
the 1997-1998 fiscal year.
    
 
                                       22
<PAGE>
   
    In addition, the State is party to other claims and litigations which its
counsel has advised are not probable of adverse court decisions. Although the
amounts of potential losses, if any, are not presently determinable, it is the
State's opinion that its ultimate liability in these cases is not expected to
have a material adverse effect on the State's financial position in the
1997-1998 fiscal year or thereafter.
    
 
   
    OTHER LOCALITIES.  Certain localities in addition to the City could have
financial problems leading to requests for additional State assistance during
the State's 1997-98 fiscal year and thereafter. The potential impact on the
State of such actions by localities is not included in the projections of the
State receipts and disbursements in the State's 1997-98 fiscal year.
    
 
    For example, fiscal difficulties experienced by the City of Yonkers
("Yonkers") resulted in the creation of the Financial Control Board for the City
of Yonkers (the "Yonkers Board") by the State in 1984. The Yonkers Board is
charged with oversight of the fiscal affairs of Yonkers. Future actions taken by
the Governor or the State Legislature to assist Yonkers could result in
increased state expenditures for extra ordinary local assistance.
 
PORTFOLIO MANAGEMENT
 
   
    The Fund's portfolio turnover rate during the fiscal year ended December 31,
1997 was approximately 10%. It is anticipated that the Fund's portfolio turnover
rate will not exceed 50% during the fiscal year ending December 31, 1998. A 50%
turnover rate would occur, for example, if 50% of the securities held in the
Fund's portfolio (excluding all securities whose maturities at acquisition were
one year or less) were sold and replaced within one year. However, the Fund may
engage in short-term trading consistent with its investment objective.
Securities may be sold in anticipation of a market decline (a rise in interest
rates) or purchased in anticipation of a market rise (a decline in interest
rates). In addition, a security may be sold and another security of comparable
quality purchased at approximately the same time to take advantage of what the
Investment Manager believes to be a temporary disparity in the normal yield
relationship between the two securities. These yield disparities may occur for
reasons not directly related to the investment quality of particular issues or
the general movement of interest rates, such as changes in the overall demand
for, or supply of, various types of tax-exempt securities.
    
 
    In general, purchases and sales may also be made to restructure the
portfolio in terms of average maturity, quality, coupon yield, or
diversification for any one or more of the following purposes: (a) to increase
income, (b) to improve portfolio quality, (c) to minimize capital depreciation,
(d) to realize gains or losses, or for such other reasons as the Investment
Manager deems relevant in light of economic and market conditions.
 
    The Fund does not generally intend to invest more than 25% of its total
assets in securities of any one governmental unit. Subject to investment
restriction number 3 in the Prospectus, the Fund may invest more than 25% of its
total assets in industrial development and pollution control bonds (two kinds of
tax-exempt Municipal Bonds).
 
    The Fund may invest in obligations customarily sold to institutional
investors in private transactions with the issuers thereof and up to 5% of its
total assets in securities for which a BONA FIDE market does not exist at the
time of purchase. With respect to any securities as to which a BONA FIDE market
does not exist, the Fund may be unable to dispose of such securities promptly at
reasonable prices. It is the Fund's current intention not to invest in such
obligations.
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    In addition to the investment restrictions enumerated in the Prospectus, the
investment restrictions listed below have been adopted by the Fund as
fundamental policies, which may not be changed without the vote of a majority of
the outstanding voting securities of the Fund, as defined in the Act. Such a
majority is defined as the lesser of (a) 67% of the shares present at a meeting
of shareholders, if the holders of more than 50% of the outstanding shares of
the Fund are present or represented by proxy or (b) more than 50% of the
outstanding shares of the Fund. For purposes of the following restrictions and
those recited in the Prospectus: (a) an "issuer" of a security is the entity
whose assets and revenues are
 
                                       23
<PAGE>
committed to the payment of interest and principal on that particular security,
provided that securities guaranteed by separate entities will be considered
separate securities; (b) a "taxable security" is any security the interest on
which is subject to federal income tax; and (c) all percentage limitations apply
immediately after a purchase or initial investment, and any subsequent change in
any applicable percentage resulting from market fluctuations or other changes in
total or net assets does not require elimination of any security from the
portfolio.
 
    The Fund may not:
 
         1. Invest in common stock.
 
         2. Invest in securities of any issuer if, to the knowledge of the Fund,
    any officer or Trustee of the Fund or officer or director of the Investment
    Manager owns more than 1/2 of 1% of the outstanding securities of such
    issuer, and such officers and directors who own more than 1/2 of 1% own in
    the aggregate more than 5% of the outstanding securities of such issuer.
 
         3. Purchase or sell real estate or interests therein, although it may
    purchase securities secured by real estate or interests therein.
 
         4. Purchase or sell commodities except that the Fund may purchase
    financial futures contracts and related options in accordance with
    procedures adopted by the Trustees described in its Prospectus and Statement
    of Additional Information.
 
         5. Purchase oil, gas or other mineral leases, rights or royalty
    contracts, or exploration or development programs.
 
         6. Write, purchase or sell puts, calls, or combinations thereof except
    options on futures contracts or options on debt securities.
 
         7. Purchase securities of other investment companies, except in
    connection with a merger, consolidation, reorganization or acquisition of
    assets.
 
         8. Borrow money, except that the Fund may borrow from a bank for
    temporary or emergency purposes in amounts not exceeding 5% (taken at the
    lower of cost or current value) of the value of its total assets (not
    including the amount borrowed).
 
         9. Pledge its assets or assign or otherwise encumber them except to
    secure permitted borrowings. (For the purpose of this restriction,
    collateral arrangements with respect to the writing of options and
    collateral arrangements with respect to initial margin for futures are not
    deemed to be pledges of assets and neither such arrangements nor the
    purchase or sale of futures are deemed to be the issuance of a senior
    security as set forth in restriction 10.)
 
        10. Issue senior securities as defined in the Act except insofar as the
    Fund may be deemed to have issued a senior security by reason of: (a)
    entering into any repurchase agreement; (b) purchasing any securities on a
    when-issued or delayed delivery basis; or (c) borrowing money in accordance
    with restrictions described above.
 
        11. Make loans of money or securities, except: (a) by the purchase of
    debt obligations in which the Fund may invest consistent with its investment
    objective and policies; (b) by investment in repurchase agreements; and (c)
    by lending its portfolio securities.
 
        12. Make short sales of securities.
 
        13. Purchase securities on margin, except for such short-term loans as
    are necessary for the clearance of purchases of portfolio securities. The
    deposit or payment by the Fund of initial or variation margin in connection
    with futures contracts or related options thereon is not considered the
    purchase of a security on margin.
 
        14. Engage in the underwriting of securities, except insofar as the Fund
    may be deemed an underwriter under the Securities Act of 1933 in disposing
    of a portfolio security.
 
        15. Invest for the purpose of exercising control or management of any
    other issuer.
 
                                       24
<PAGE>
    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.
 
PORTFOLIO TRANSACTIONS AND BROKERAGE
- --------------------------------------------------------------------------------
 
   
    The Investment Manager is responsible for decisions to buy and sell
securities and commodities for the Fund, the selection of brokers and dealers to
effect the transactions, and the negotiation of brokerage commissions, if any.
The Fund expects that the primary market for the securities in which it intends
to invest will generally be the over-the-counter market. Securities are
generally traded in the over-the-counter market on a "net" basis with dealers
acting as principal for their own accounts without charging a stated commission,
although the price of the security usually includes a profit to the dealer.
Options and futures transactions will usually be effected through a broker and a
commission will be charged. The Fund also expects that securities will be
purchased at times in underwritten offerings where the price includes a fixed
amount of compensation, generally referred to as the underwriter's concession or
discount. On occasion, the Fund may also purchase certain money market
instruments directly from an issuer, in which case no commissions or discounts
are paid. During the fiscal years ended December 31, 1995, 1996 and 1997, the
Fund did not pay any brokerage commissions.
    
 
    The Investment Manager currently serves as investment manager to a number of
clients, including other investment companies, and may in the future act as
investment manager or adviser to others. It is the practice of the Investment
Manager to cause purchase and sale transactions to be allocated among the Fund
and others whose assets it manages in such manner as it deems equitable. In
making such allocations among the Fund and other client accounts, various
factors are considered, including the respective investment objectives, the
relative size of portfolio holdings of the same or comparable securities, the
availability of cash for investment, the size of investment commitments
generally held and the opinions of the persons responsible for managing the
portfolios of the Fund and other client accounts. In the case of certain initial
and secondary public offerings, the Investment Manager may utilize a pro rata
allocation process based on the size of the Dean Witter Funds involved and the
number of shares available from the public offering.
 
    The policy of the Fund, regarding purchases and sales of securities for its
portfolio, is that primary consideration be given to obtaining the most
favorable prices and efficient execution of transactions. In seeking to
implement the Fund's policies, the Investment Manager effects transactions with
those brokers and dealers who the Investment Manager believes provide the most
favorable prices and are capable of providing efficient executions. If the
Investment Manager believes such price and executions are obtainable from more
than one broker or dealer, it may give consideration to placing portfolio
transactions with those brokers and dealers who also furnish research and other
services to the Fund or the Investment Manager. Such services may include, but
are not limited to, any one or more of the following: information as to the
availability of securities for purchase or sale; statistical or factual
information or opinions pertaining to investment; wire services; and appraisals
or evaluations of portfolio securities.
 
    The information and services received by the Investment Manager from brokers
and dealers may be of benefit to the Investment Manager in the management of
accounts of some of its other clients and may not, in every case, benefit the
Fund directly. While the receipt of such information and services is useful in
varying degrees and would generally reduce the amount of research or services
otherwise performed by the Investment Manager and thereby reduce its expenses,
it is of indeterminable value and the Fund will not reduce the management fee it
pays to the Investment Manager by any amount that may be attributable to the
value of such services.
 
    Pursuant to an order of the Securities and Exchange Commission, the Fund may
effect principal transactions in certain money market instruments with DWR. The
Fund will limit its transactions with DWR to U.S. Government and Government
Agency Securities, Bank Money Instruments (i.e. Certificates of Deposit and
Bankers' Acceptances) and Commercial Paper. Such transactions will be effected
with
 
                                       25
<PAGE>
   
DWR only when the price available from DWR is better than that available from
other dealers. During the fiscal years ended December 31, 1995, 1996 and 1997,
the Fund did not effect any principal transactions with DWR.
    
 
   
    Consistent with the policy described above, brokerage transactions in
securities listed on exchanges or admitted to unlisted trading privileges may be
effected through DWR, Morgan Stanley & Co. Incorporated and other affiliated
brokers and dealers. In order for an affiliated broker or dealer to effect
portfolio transactions for the Fund, the commissions, fees or other remuneration
received by the affiliated broker or dealer must be reasonable and fair compared
to the commissions, fees or other remuneration paid to other brokers in
connection with comparable transactions involving similar securities being
purchased or sold on an exchange during a comparable period of time. This
standard would allow the affiliated broker or dealer to receive no more than the
remuneration which would be expected to be received by an unaffiliated broker in
a commensurate arms-length transaction. Furthermore, the Trustees of the Fund,
including a majority of the Trustees who are not "interested" Trustees, have
adopted procedures which are reasonably designed to provide that any
commissions, fees or other remuneration paid to an affiliated broker or dealer
are consistent with the foregoing standard.
    
 
THE DISTRIBUTOR
- --------------------------------------------------------------------------------
 
   
    As discussed in the Prospectus, shares of the Fund are distributed by Dean
Witter Distributors Inc. (the "Distributor"), on a continuous basis. The
Distributor has entered into a selected dealer agreement with DWR, which through
its own sales organization sells shares of the Fund. In addition, the
Distributor may enter into selected dealer agreements with other selected
dealers. The Distributor, a Delaware corporation, is a wholly-owned subsidiary
of MSDW. The Trustees, including a majority of the Trustees who are not and were
not at the time they voted "interested persons" of the Fund, as defined in the
Act (the "Independent Trustees"), approved, at their meeting held on June 30,
1997 the current Distribution Agreement appointing the Distributor exclusive
distributor of the Fund's shares and providing for the Distributor to bear
distribution expenses not borne by the Fund. By its terms, the Distribution
Agreement has an initial term ending April 30, 1998 and will remain in effect
from year to year thereafter if approved by the Board.
    
 
    The Distributor bears all expenses it may incur in providing services under
the Distribution Agreement. Such expenses include the payment of commissions for
sales of the Fund's shares and incentive compensation to account executives. The
Distributor also pays certain expenses in connection with the distribution of
the Fund's shares, including the costs of preparing, printing and distributing
advertising or promotional materials, and the costs of printing and distributing
prospectuses and supplements thereto used in connection with the offering and
sale of the Fund's shares. The Fund bears the costs of initial typesetting,
printing and distribution of prospectuses and supplements thereto to
shareholders. The Fund also bears the costs of registering the Fund and its
shares under federal securities laws and pays filing fees in accordance with
state securities laws. The Fund and the Distributor have agreed to indemnify
each other against certain liabilities, including liabilities under the
Securities Act of 1933, as amended. Under the Distribution Agreement, the
Distributor uses its best efforts in rendering services to the Fund, but in the
absence of willful misfeasance, bad faith, gross negligence or reckless
disregard of its obligations, the Distributor is not liable to the Fund or any
of its shareholders for any error of judgment or mistake of law or for any act
or omission or for losses sustained by the Fund or its shareholders.
 
PLAN OF DISTRIBUTION
 
    The Fund has adopted a Plan of Distribution pursuant to Rule 12b-1 under the
Act (the "Plan") pursuant to which each Class, other than Class D, pays the
Distributor compensation accrued daily and payable monthly at the following
annual rates: 0.25% and 0.75% of the average daily net assets of Class A and
Class C, respectively, and, with respect to Class B, 0.75% of the lesser of: (a)
the average daily aggregate gross sales of the Fund's Class B shares since the
inception of the Fund (not including reinvestments of dividends or capital gains
distributions), less the average daily aggregate net asset value of the Fund's
Class B shares redeemed since the Fund's inception upon which a contingent
 
                                       26
<PAGE>
   
deferred sales charge has been imposed or upon which such charge has been
waived, or (b) the average daily net assets of Class B. The Distributor also
receives the proceeds of front-end sales charges and of contingent deferred
sales charges imposed on certain redemptions of shares, which are separate and
apart from payments made pursuant to the Plan (see "Purchase of Fund Shares" in
the Prospectus). The Distributor has informed the Fund that it and/or DWR
received (a) approximately $337,000, $224,082 and $281,986 in contingent
deferred sales charges from Class B for the fiscal years ended December 31,
1995, 1996 and 1997, respectively, and (b) approximately $993 in front-end sales
charges from Class A for the fiscal year ended December 31, 1997, none of which
was retained by the Distributor. No contingent deferred sales charges were
received from Class A or Class C for the fiscal year ended December 31, 1997.
    
 
    The Distributor has informed the Fund that the entire fee payable by Class A
and a portion of the fees payable by each of Class B and Class C each year
pursuant to the Plan equal to 0.20% of the average daily net assets of Class B
and 0.25% of the average daily net assets of Class C are currently each
characterized as a "service fee" under the Rules of the Association of the
National Association of Securities Dealers, Inc. (of which the Distributor is a
member). The "service fee" is a payment made for personal service and/or the
maintenance of shareholder accounts. The remaining portion of the Plan fees
payable by a Class, if any, is characterized as an "asset-based sales charge" as
such is defined by the aforementioned Rules of the Association.
 
    The Plan was adopted by a majority vote of the Board of Trustees, including
all of the Trustees of the Fund who are not "interested persons" of the Fund (as
defined in the Act) and who have no direct or indirect financial interest in the
operation of the Plan (the "Independent 12b-1 Trustees"), cast in person at a
meeting called for the purpose of voting on the Plan, on February 13, 1985, by
the then sole shareholder of the Fund on March 20, 1985 and by the shareholders
holding a majority, as defined in the Act, of the outstanding voting securities
of the Fund at a Special Meeting of Shareholders of the Fund held on April 29,
1986.
 
    At their meeting held on October 30, 1992, the Trustees of the Fund,
including all of the Independent 12b-1 Trustees, approved certain amendments to
the Plan which took effect in January, 1993 and were designed to reflect the
fact that upon an internal reorganization the share distribution activities
theretofore performed for the Fund by DWR were assumed by the Distributor and
DWR's sales activities are now being performed pursuant to the terms of a
selected dealer agreement between the Distributor and DWR. The amendments
provide that payments under the Plan will be made to the Distributor rather than
to DWR as before the amendment, and that the Distributor in turn is authorized
to make payments to DWR, its affiliates or other selected broker-dealers (or
direct that the Fund pay such entities directly). The Distributor is also
authorized to retain part of such fee as compensation for its own
distribution-related expenses. At their meeting held on April 28, 1993, the
Trustees, including a majority of the Independent 12b-1 Trustees, approved
certain technical amendments to the Plan in connection with amendments adopted
by the National Association of Securities Dealers, Inc. to its Rules of the
Association. At their meeting held on October 26, 1995, the Trustees of the
Fund, including all of the Independent 12b-1 Trustees, approved an amendment to
the Plan to permit payments to be made under the Plan with respect to certain
distribution expenses incurred in connection with the distribution of shares,
including personal services to shareholders with respect to holdings of such
shares, of an investment company whose assets are acquired by the Fund in a
tax-free reorganization. At their meeting held on June 30, 1997, the Trustees,
including a majority of the Independent 12b-1 Trustees, approved amendments to
the Plan to reflect the multiple-class structure for the Fund, which took effect
on July 28, 1997.
 
   
    Under the Plan and as required by Rule 12b-1, the Trustees receive and
review promptly after the end of each calendar quarter a written report provided
by the Distributor of the amounts expended under the Plan and the purpose for
which such expenditures were made. Class B shares of the Fund accrued amounts
payable to the Distributor under the Plan, during the fiscal year ended December
31, 1997, of $1,337,215. This amount is equal to 0.75% of the Fund's average
daily net assets for the fiscal year and was calculated pursuant to clause (b)
of the compensation formula under the Plan. This amount is treated by the Fund
as an expense in the year it is accrued. For the fiscal period July 28 through
    
 
                                       27
<PAGE>
   
December 31, 1997, Class A and Class C shares of the Fund accrued payments under
the Plan amounting to $60 and $210, respectively, which amounts are equal to
0.25% and 0.75% of the average daily net assets of Class A and Class C,
respectively, for such period.
    
 
    The Plan was adopted in order to permit the implementation of the Fund's
method of distribution. Under this distribution method the Fund offers four
Classes of shares, each with a different distribution arrangement as set forth
in the Prospectus.
 
    With respect to Class A shares, DWR compensates its account executives by
paying them, from proceeds of the front-end sales charge, commissions for the
sale of Class A shares, currently a gross sales credit of up to 4.0% of the
amount sold (except as provided in the following sentence) and an annual
residual commission, currently a residual of up to 0.20% of the current value of
the respective accounts for which they are the account executives or dealers of
record in all cases. On orders of $1 million or more (for which no sales charge
was paid), the Investment Manager compensates DWR's account executives by paying
them, from its own funds, a gross sales credit of 1.0% of the amount sold.
 
    With respect to Class B shares, DWR compensates its account executives by
paying them, from its own funds, commissions for the sale of Class B shares,
currently a gross sales credit of up to 4.0% of the amount sold and an annual
residual commission, currently a residual of up to 0.20% of the current value
(not including reinvested dividends or distributions) of the amount sold in all
cases.
 
    With respect to Class C shares, DWR compensates its account executives by
paying them, from its own funds, commissions for the sale of Class C shares,
currently a gross sales credit of up to 1.0% of the amount sold and an annual
residual commission, currently a residual of up to 0.75% of the current value of
the respective accounts for which they are the account executives of record.
 
    With respect to Class D shares other than shares held by participants in
InterCapital's mutual fund asset allocation program, the Investment Manager
compensates DWR's account executives by paying them, from its own funds,
commissions for the sale of Class D shares, currently a gross sales credit of up
to 1.0% of the amount sold. There is a chargeback of 100% of the amount paid if
the Class D shares are redeemed in the first year and a chargeback of 50% of the
amount paid if the Class D shares are redeemed in the second year after
purchase. The Investment Manager also compensates DWR's account executives by
paying them, from its own funds, an annual residual commission, currently a
residual of up to 0.10% of the current value of the respective accounts for
which they are the account executives of record (not including accounts of
participants in the InterCapital mutual fund asset allocation program).
 
   
    The gross sales credit is a charge which reflects commissions paid by DWR to
its account executives and DWR's Fund-associated distribution-related expenses,
including sales compensation, and overhead and other branch office
distribution-related expenses including (a) the expenses of operating DWR's
branch offices in connection with the sale of Fund shares, including lease
costs, the salaries and employee benefits of operations and sales support
personnel, utility costs, communications costs and the costs of stationery and
supplies, (b) the costs of client sales seminars, (c) travel expenses of mutual
fund sales coordinators to promote the sale of Fund shares and (d) other
expenses relating to branch promotion of Fund sales. The distribution fee that
the Distributor receives from the Fund under the Plan, in effect, offsets
distribution expenses incurred under the Plan on behalf of the Fund and, in the
case of Class B shares, opportunity costs, such as the gross sales credit and an
assumed interest charge thereon ("carrying charge"). In the Distributor's
reporting of the distribution expenses to the Fund, in the case of Class B
shares, such assumed interest (computed at the "broker's call rate") has been
calculated on the gross credit as it is reduced by amounts received by the
Distributor under the Plan and any contingent deferred sales charges received by
the Distributor upon redemption of shares of the Fund. No other interest charge
is included as a distribution expense in the Distributor's calculation of its
distribution costs for this purpose. The broker's call rate is the interest rate
charged to securities brokers on loans secured by exchange-listed securities.
    
 
    The Fund is authorized to reimburse expenses incurred or to be incurred in
promoting the distribution of the Fund's Class A and Class C shares and in
servicing shareholder accounts. Reimbursement
 
                                       28
<PAGE>
will be made through payments at the end of each month. The amount of each
monthly payment may in no event exceed an amount equal to a payment at the
annual rate of 0.25%, in the case of Class A, and 0.75%, in the case of Class C,
of the average net assets of the respective Class during the month. No interest
or other financing charges, if any, incurred on any distribution expenses on
behalf of Class A and Class C will be reimbursable under the Plan. With respect
to Class A, in the case of all expenses other than expenses representing the
service fee, and, with respect to Class C, in the case of all expenses other
than expenses representing a gross sales credit or a residual to account
executives, such amounts shall be determined at the beginning of each calendar
quarter by the Trustees, including a majority of the Independent 12b-1 Trustees.
Expenses representing the service fee (for Class A) or a gross sales credit or a
residual to account executives (for Class C) may be reimbursed without prior
determination. In the event that the Distributor proposes that monies shall be
reimbursed for other than such expenses, then in making quarterly determinations
of the amounts that may be reimbursed by the Fund, the Distributor will provide
and the Trustees will review a quarterly budget of projected distribution
expenses to be incurred on behalf of the Fund, together with a report explaining
the purposes and anticipated benefits of incurring such expenses. The Trustees
will determine which particular expenses, and the portions thereof, that may be
borne by the Fund, and in making such a determination shall consider the scope
of the Distributor's commitment to promoting the distribution of the Fund's
Class A and Class C shares.
 
   
    Each Class paid 100% of the amounts accrued under the Plan with respect to
that Class fiscal year ended December 31, 1997 to the Distributor. The
Distributor and DWR estimate that they have spent, pursuant to the Plan,
$20,638,645 on behalf of the Fund since the inception of the Plan. It is
estimated that this amount was spent in approximately the following ways: (i)
13.43% ($2,772,193)--advertising and promotional expenses; (ii) 1.20%
($248,142)--printing of prospectuses for distribution to other than current
shareholders; and (iii) 85.37% ($17,618,310)--other expenses, including the
gross sales credit and the carrying charge, of which 9.76% ($1,719,232)
represents carrying charges, 36.59% ($6,447,076) represents commission credits
to DWR branch offices for payments of commissions to account executives and
53.65% ($9,452,002) represents overhead and other branch office
distribution-related expenses. The amounts accrued by Class A and Class C for
distribution during the fiscal period July 28 through December 31, 1997 were for
expenses which relate to compensation of sales personnel and associated overhead
expenses.
    
 
   
    In the case of Class B shares, at any given time, the expenses of
distributing shares of the Fund may be more or less than the total of (i) the
payments made by the Fund pursuant to the Plan and (ii) the proceeds of
contingent deferred sales charges paid by investors upon redemption of shares.
The Distributor has advised the Fund that in the case of Class B shares, the
excess distribution expenses, including the carrying charge designed to
approximate the opportunity costs incurred by DWR which arise from it having
advanced monies without having received the amount of any sales charges imposed
at the time of sale of the Fund's Class B shares, totalled $1,970,148, which was
equal to 1.16% of the net assets of the Fund as of December 31, 1997. Because
there is no requirement under the Plan that the Distributor be reimbursed for
all distribution expenses with respect to Class B shares or any requirement that
the Plan be continued from year to year, this excess amount does not constitute
a liability of the Fund. Although there is no legal obligation for the Fund to
pay expenses incurred in excess of payments made to the Distributor under the
Plan and the proceeds of contingent deferred sales charges paid by investors
upon redemption of shares, if for any reason the Plan is terminated, the
Trustees will consider at that time the manner in which to treat such expenses.
Any cumulative expenses incurred, but not yet recovered through distribution
fees or contingent deferred sales charges, may or may not be recovered through
future distribution fees or contingent deferred sales charges.
    
 
    No interested person of the Fund nor any Trustee of the Fund who is not an
interested person of the Fund, as defined in the Act, has any direct financial
interest in the operation of the Plan except to the extent that the Distributor,
InterCapital, DWR, DWSC or certain of their employees may be deemed to have such
an interest as a result of benefits derived from the successful operation of the
Plan or as a result of receiving a portion of the amounts expended thereunder by
the Fund.
 
                                       29
<PAGE>
    Under its terms, the Plan had an initial term ending December 31, 1985 and
will continue from year to year thereafter, provided such continuance is
approved annually by a vote of the Trustees in the manner described above. Prior
to the Board's approval of amendments to the Plan to reflect the multiple-class
structure for the Fund, the most recent continuance of the Plan for one year,
until April 30, 1998, was approved by the Board of Trustees of the Fund,
including a majority of the Independent 12b-1 Trustees, at a Board meeting held
on April 24, 1997. Prior to approving the continuation of the Plan, the Trustees
requested and received from the Distributor and reviewed all the information
which they deemed necessary to arrive at an informed determination. In making
their determination to continue the Plan, the Trustees considered: (1) the
Fund's experience under the Plan and whether such experience indicates that the
Plan is operating as anticipated; (2) the benefits the Fund had obtained, was
obtaining and would be likely to obtain under the Plan; and (3) what services
had been provided and were continuing to be provided under the Plan to the Fund
and its shareholders. Based upon their review, the Trustees of the Fund,
including each of the Independent 12b-1 Trustees, determined that continuation
of the Plan would be in the best interest of the Fund and would have a
reasonable likelihood of continuing to benefit the Fund and its shareholders. In
the Trustees' quarterly review of the Plan, they will consider its continued
appropriateness and the level of compensation provided therein.
 
    The Plan may not be amended to increase materially the amount to be spent
for the services described therein without approval by the shareholders of the
affected Class or Classes of the Fund, and all material amendments to the Plan
must also be approved by the Trustees in the manner described above. The Plan
may be terminated at any time, without payment of any penalty, by vote of a
majority of the Independent 12b-1 Trustees or by a vote of a majority of the
outstanding voting securities of the Fund (as defined in the Act) on not more
than thirty days' written notice to any other party to the Plan. So long as the
Plan is in effect, the election and nomination of Independent 12b-1 Trustees
shall be committed to the discretion of the Independent 12b-1 Trustees.
 
DETERMINATION OF NET ASSET VALUE
- --------------------------------------------------------------------------------
 
    As discussed in the Prospectus, portfolio securities (other than short-term
debt securities and futures and options) are valued for the Fund by an outside
independent pricing service approved by the Board of Trustees. The pricing
service has informed the Fund that in valuing the Fund's portfolio securities it
uses both a computerized grid matrix of tax-exempt securities and evaluations by
its staff, in each case based on information concerning market transactions and
quotations from dealers which reflect the bid side of the market each day. The
Fund's portfolio securities are thus valued by reference to a combination of
transactions and quotations for the same or other securities believed to be
comparable in quality, coupon, maturity, type of issue, call provisions, trading
characteristics and other features deemed to be relevant. The Board of Trustees
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 service, using the procedures outlined above
and subject to periodic review, are more likely to approximate the fair value of
such securities.
 
    The Investment Manager will periodically review and evaluate the procedures,
methods and quality of services provided by the pricing service then being used
by the Fund and may, from time to time, recommend to the Board of Trustees the
use of other pricing services or discontinuance of the use of any pricing
service in whole or part. The Board may determine to approve such recommendation
or to make other provisions for pricing of the Fund's portfolio securities.
Short-term taxable debt securities with sixty days or less remaining to maturity
at time of purchase are valued at amortized cost, unless the Board determines
such does not reflect the securities' fair value, in which case these securities
will be valued at their fair value as determined by the Board of Trustees. Other
short-term taxable debt securities will be valued on a mark to market basis
until such time as they have a remaining maturity of sixty days, whereupon they
will be valued at amortized cost using their value on the 61st day unless the
Trustees determine such value does not reflect the securities' market value, in
which case these securities will be valued at their fair market value as
determined by the Trustees. Listed options on debt securities are valued at the
latest sale price on the exchange on which they are listed unless no sales of
such options have taken
 
                                       30
<PAGE>
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 the latest bid and asked price. Futures contracts and options
thereon which are traded on commodities exchanges are valued at their latest
sale price on such commodities exchanges unless the Trustees determine that such
price does not reflect their market value, in which case they will be valued at
their fair value as determined by the Trustees. All other securities, including
illiquid 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.
 
   
    As stated in the Prospectus, the net asset value for each Class of shares of
the Fund will be computed once daily at 4:00 P.M., New York time (or, on days
when the New York Stock Exchange closes prior to 4:00 P.M., at such earlier
time), on each day that the New York Stock Exchange is open. The New York Stock
Exchange currently observes the following holidays: New Year's Day, Reverend Dr.
Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.
    
 
PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
    As discussed in the Prospectus, the Fund offers four Classes of shares as
follows:
 
INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES
 
    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 in the circumstances
discussed in the Prospectus.
 
    RIGHT OF ACCUMULATION.  As discussed in the Prospectus, investors may
combine the current value of shares purchased in separate transactions for
purposes of benefitting from the reduced sales charges available for purchases
of shares of the Fund totalling at least $25,000 in net asset value. For
example, if any person or entity who qualifies for this privilege holds Class A
shares of the Fund and/or other Dean Witter Funds that are multiple class funds
("Dean Witter Multi-Class Funds") or shares of other Dean Witter Funds sold with
a front-end sales charge purchased at a price including a front-end sales charge
having a current value of $5,000, and purchases $20,000 of additional shares of
the Fund, the sales charge applicable to the $20,000 purchase would be 4.0% of
the offering price.
 
   
    The Distributor must be notified by the 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 selected broker-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 Distributor or Morgan Stanley Dean Witter Trust FSB (the
"Transfer Agent") fails to confirm the investor's represented holdings.
    
 
    LETTER OF INTENT.  As discussed in the Prospectus, reduced sales charges are
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
the Distributor or from a single Selected Broker-Dealer.
 
    A Letter of Intent permits an investor to establish a total investment goal
to be achieved by any number of purchases over a thirteen-month period. Each
purchase of Class A shares made during the period will receive the reduced sales
commission applicable to the amount represented by the goal, as if it were a
single purchase. A number of shares equal in value to 5% of the dollar amount of
the Letter of Intent will be held in escrow by the Transfer Agent, in the name
of the shareholder. The initial purchase under a Letter of Intent must be equal
to at least 5% of the stated investment goal.
 
    The Letter of Intent does not obligate the investor to purchase, nor the
Fund to sell, the indicated amount. In the event the Letter of Intent goal is
not achieved within the thirteen-month period, the investor is required to pay
the difference between the sales charge otherwise applicable to the
 
                                       31
<PAGE>
purchases made during this period and sales charges actually paid. Such payment
may be made directly to the Distributor or, if not paid, the Distributor is
authorized by the shareholder to liquidate a sufficient number of his or her
escrowed shares to obtain such difference.
 
    If the goal is exceeded and purchases pass the next sales charge level, the
sales charge on the entire amount of the purchase that results in passing that
level and on subsequent purchases will be subject to further reduced sales
charges in the same manner as set forth above under "Right of Accumulation," but
there will be no retroactive reduction of sales charges on previous purchases.
For the purpose of determining whether the investor is entitled to a further
reduced sales charge applicable to purchases at or above a sales charge level
which exceeds the stated goal of a Letter of Intent, the cumulative current net
asset value of any shares owned by the investor in any other Dean Witter Funds
held by the shareholder which were 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) will be added to
the cost or net asset value of shares of the Fund owned by the investor.
However, shares of "Exchange Funds" (see "Shareholder Services--Exchange
Privilege") and the purchase of shares of other Dean Witter Funds will not be
included in determining whether the stated goal of a Letter of Intent has been
reached.
 
    At any time while a Letter of Intent is in effect, a shareholder may, by
written notice to the Distributor, increase the amount of the stated goal. In
that event, only shares purchased during the previous 90-day period and still
owned by the shareholder will be included in the new sales charge reduction. The
5% escrow and minimum purchase requirements will be applicable to the new stated
goal. Investors electing to purchase shares of the Fund pursuant to a Letter of
Intent should carefully read such Letter of Intent.
 
CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE--CLASS B SHARES
 
    Class B shares are sold without an initial sales charge but are subject to a
CDSC payable upon most redemptions within six years after purchase. As stated in
the Prospectus, a CDSC will be imposed on any redemption by an investor if after
such redemption the current value of the investor's Class B shares of the Fund
is less than the dollar amount of all payments by the shareholder for the
purchase of Class B shares during the preceding six years. However, no CDSC will
be imposed to the extent that the net asset value of the shares redeemed does
not exceed: (a) the current net asset value of shares purchased more than six
years prior to the redemption, plus (b) the current net asset value of shares
purchased through reinvestment of dividends or distributions of the Fund or
another Dean Witter Fund (see "Shareholder Services--Targeted Dividends"), plus
(c) the current net asset value of shares acquired in exchange for (i) shares of
Dean Witter front-end sales charge funds, or (ii) shares of other Dean Witter
Funds for which shares of front-end sales charge funds have been exchanged (see
"Shareholder Services--Exchange Privilege"), plus (d) increases in the net asset
value of the investor's shares above the total amount of payments for the
purchase of Fund shares made during the preceding six years. The CDSC will be
paid to the Distributor.
 
    In determining the applicability of the CDSC to each redemption, the amount
which represents an increase in the net asset value of the investor's shares
above the amount of the total payments for the purchase of shares within the
last six years will be redeemed first. In the event the redemption amount
exceeds such increase in value, the next portion of the amount redeemed will be
the amount which represents the net asset value of the investor's shares
purchased more than six years prior to the redemption and/or shares purchased
through reinvestment of dividends or distributions and/or shares acquired in
exchange for shares of Dean Witter front-end sales charge funds, or for shares
of other Dean Witter funds for which shares of front-end sales charge funds have
been exchanged. A portion of the amount redeemed which exceeds an amount which
represents both such increase in value and the value of shares purchased more
than six years prior to the redemption and/or shares purchased through
reinvestment of dividends or distributions and/or shares acquired in the
above-described exchanges will be subject to a CDSC.
 
                                       32
<PAGE>
    The amount of the CDSC, if any, will vary depending on the number of years
from the time of payment for the purchase of Class B shares of the Fund until
the time of redemption of such shares. For purposes of determining the number of
years from the time of any payment for the purchase of shares, all payments made
during a month will be aggregated and deemed to have been made on the last day
of the month. The following table sets forth the rates of the CDSC applicable to
Class B shares of the Fund:
 
<TABLE>

<S>                                                                                         <C>
First.....................................................................................               5.0%

Sixth.....................................................................................               1.0%
Seventh and thereafter....................................................................             None
</TABLE>
 
    In determining the rate of the CDSC, it will be assumed that a redemption is
made of shares held by the investor for the longest period of time within the
applicable six-year period. This will result in any such CDSC being imposed at
the lowest possible rate. The CDSC will be imposed, in accordance with the table
shown above, on any redemptions within six years of purchase which are in excess
of these amounts and which redemptions do not qualify for waiver of the CDSC, as
described in the Prospectus.
 
LEVEL LOAD ALTERNATIVE--CLASS C SHARES
 
    Class C shares are sold without a sales charge but are subject to a CDSC of
1.0% on most redemptions made within one year after purchase, except in the
circumstances discussed in the Prospectus.
 
NO LOAD ALTERNATIVE--CLASS D SHARES
 
    Class D shares are offered without any sales charge on purchase or
redemption. Class D shares are offered only to those persons meeting the
qualifications set forth in the Prospectus.
 
SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 
    Upon the purchase of shares of the Fund, a Shareholder Investment Account is
opened for the investor on the books of the Fund and maintained by the Transfer
Agent. This is an open account in which shares owned by the investor are
credited by the Transfer Agent in lieu of issuance of a share certificate. If a
share certificate is desired, it must be requested in writing for each
transaction. Certificates are issued only for full shares and may be redeposited
in the account at any time. There is no charge to the investor for issuance of a
certificate. Whenever a shareholder instituted transaction takes place in the
Shareholder Investment Account, the shareholder will be mailed a statement
reflecting the status of such Account.
 
    AUTOMATIC INVESTMENT OF DIVIDENDS AND DISTRIBUTIONS.  As stated in the
Prospectus, all income dividends and capital gains distributions are
automatically paid in full and fractional shares of the applicable Class of the
Fund, unless the shareholder requests that they be paid in cash. Each purchase
of shares of the Fund is made upon the condition that the Transfer Agent is
thereby automatically appointed as agent of the investor to receive all
dividends and capital gains distributions on shares owned by the investor. Such
dividends and distributions will be paid, at the net asset value per share, in
shares of the applicable Class of the Fund (or in cash if the shareholder so
requests) as of the close of business on the monthly payment date, as stated in
the Prospectus. At any time an investor may request the Transfer Agent, in
writing, to have subsequent dividends and/or capital gains distributions paid to
him or her in cash rather than shares. To assure sufficient time to process the
change, such request should be received by the Transfer Agent at least five
business days prior to the payment date of the dividend or the record date of
the distribution. In the case of recently purchased shares for which
registration instructions have not been received on the payment or record date,
cash payments will be
 
                                       33
<PAGE>
   
made to DWR or other selected broker-dealers, and will be forwarded to the
shareholder, upon the receipt of proper instructions. It has been and remains
the Fund's policy and practice that, if checks for dividends or distributions
paid in cash remain uncashed, no interest will accrue on amounts represented by
such uncashed checks.
    
 
    TARGETED DIVIDENDS-SM-.  In states where it is legally permissible,
shareholders may also have all income dividends and capital gains distributions
automatically invested in shares of any Class of an open-end Dean Witter Fund
other than Dean Witter New York Tax-Free Income Fund or in another Class of Dean
Witter New York Tax-Free Income Fund. Such investment will be made as described
above for automatic investment in shares of the applicable Class of the Fund, at
the net asset value per share of the dividend or distribution of the selected
Dean Witter Fund as of the close of business on the payment date and will begin
to earn dividends, if any, in the selected Dean Witter Fund the next business
day. To participate in the Targeted Dividends program, shareholders should
contact their DWR or other selected broker-dealer account executive or the
Transfer Agent. Shareholders of the Fund must be shareholders of the selected
Class of the Dean Witter Fund targeted to receive investments from dividends at
the time they enter the Targeted Dividends program. Investors should review the
prospectus of the targeted Dean Witter Fund before entering the program.
 
   
    EASYINVEST-SM-.  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 a
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. Shares purchased through EasyInvest will be added to the shareholder's
existing account at the net asset value calculated the same business day the
transfer of funds is effected (subject to any applicable sales charges). Shares
of the Dean Witter money market funds redeemed in connection with EasyInvest are
redeemed on the business day preceding the transfer of funds. For further
information or to subscribe to EasyInvest, shareholders should contact their DWR
or other selected broker-dealer account executive or the Transfer Agent.
    
 
    INVESTMENT OF DIVIDENDS OR 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, without the imposition of a CDSC upon redemption, by returning
the check or the proceeds to the Transfer Agent within thirty days after the
payment date. If the shareholder returns the proceeds of a dividend or
distribution, such funds must be accompanied by a signed statement indicating
that the proceeds constitute a dividend or distribution to be invested. Such
investment will be made at the net asset value per share next determined after
receipt of the check or proceeds by the Transfer Agent.
 
    DIRECT INVESTMENTS THROUGH TRANSFER AGENT.  As discussed in the Prospectus,
a shareholder may make additional investments in any Class of shares of the Fund
for which they qualify at any time through the Shareholder Investment Account by
sending a check in any amount, not less than $100, payable to Dean Witter New
York Tax-Free Income Fund, and indicating the selected Class, directly to the
Fund's Transfer Agent. In the case of Class A shares, after deduction of any
applicable sales charge, the balance will be applied to the purchase of Fund
shares, and, in the case of shares of the other Classes, the entire amount will
be applied to the purchase of Fund shares at the net asset value per share next
computed after receipt of the check or purchase payment by the Transfer Agent.
The shares so purchased will be credited to the investor's account.
 
    SYSTEMATIC WITHDRAWAL PLAN.  As discussed in the Prospectus, 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 Withdrawal Plan provides for monthly or
quarterly (March, June, September and 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
 
                                       34
<PAGE>
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 dollar amount.
 
    The Transfer Agent acts as agent for the shareholder in tendering to the
Fund for redemption sufficient full and fractional shares to provide the amount
of the periodic withdrawal payment designated in the application. The shares
will be redeemed at their net asset value determined, at the shareholder's
option, on the tenth or twenty-fifth day (or next following business day) of the
relevant month or quarter and normally a check for the proceeds will be mailed
by the Transfer Agent, or amounts credited to a shareholder's DWR or other
selected broker-dealer account, within five business days after the date of
redemption. The Withdrawal Plan may be terminated at any time by the Fund.
 
    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. Although the
shareholder may make additional investments of $2,500 or more under the
Withdrawal Plan, withdrawals made concurrently with purchases of additional
shares may be inadvisable because of sales charges which may be applicable to
purchases or redemptions of shares (see "Purchase of Fund Shares").
 
    Any shareholder who wishes to have payments under the Withdrawal Plan made
to a third party or sent to an address other than the one listed on the account
must send complete written instructions to the Transfer Agent to enroll in the
Withdrawal Plan. The shareholder's signature on such instructions must be
guaranteed by an eligible guarantor acceptable to the Transfer Agent
(shareholders should contact the Transfer Agent for a determination as to
whether a particular institution is such an eligible guarantor). A shareholder
may, at any time, change the amount and interval of withdrawal payments through
his or her DWR or other selected broker-dealer account executive or by written
notification to the Transfer Agent. In addition, the party and/or the address to
which checks are mailed may be changed by written notification to the Transfer
Agent, with signature guarantees required in the manner described above. The
shareholder may also terminate the Withdrawal Plan at any time by written notice
to the Transfer Agent. In the event of such termination, the account will be
continued as a regular shareholder investment account. The shareholder may also
redeem all or part of the shares held in the Withdrawal Plan account (see
"Redemptions and Repurchases" in the Prospectus) at any time.
 
EXCHANGE PRIVILEGE
 
   
    As discussed in the Prospectus, the Fund makes available to its shareholders
an Exchange Privilege whereby shareholders of each Class of shares of the Fund
may exchange their shares for shares of the same Class of shares of any other
Dean Witter Multi-Class Fund without the imposition of any exchange fee. Shares
may also be exchanged for shares of any 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 foregoing nine
funds are hereinafter referred to as 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 waiting period for
exchanges of shares acquired by exchange or dividend reinvestment. An exchange
will be treated for federal income tax purposes the same as a repurchase or
redemption of shares, on which the shareholder may realize a capital gain or
loss.
    
 
                                       35
<PAGE>
    Any new account established through the Exchange Privilege will have the
same registration and cash dividend or dividend reinvestment plan as the present
account, unless the Transfer Agent receives written notification to the
contrary. For telephone exchanges, the exact registration of the existing
account and the account number must be provided.
 
    Any shares held in certificate form cannot be exchanged but must be
forwarded to the Transfer Agent and deposited into the shareholder's account
before being eligible for exchange. (Certificates mailed in for deposit should
not be endorsed.)
 
   
    As described below, and in the Prospectus under the caption "Purchase of
Fund Shares," a CDSC may be imposed upon a redemption, depending on a number of
factors, including the number of years from the time of purchase until the time
of redemption or exchange ("holding period"). When shares of a Dean Witter
Multi-Class Fund or Global Short-Term are exchanged for shares of an Exchange
Fund, the exchange is executed at no charge to the shareholder, without the
imposition of the CDSC at the time of the exchange. During the period of time
the shareholder remains in the Exchange Fund (calculated from the last day of
the month in which the Exchange Fund shares were acquired), the holding period
or "year since purchase payment made" is frozen. When shares are redeemed out of
the Exchange Fund, they will be subject to a CDSC which would be based upon the
period of time the shareholder held shares in a Dean Witter Multi-Class Fund or
in Global Short-Term. However, 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. Shareholders
acquiring shares of an Exchange Fund pursuant to this exchange privilege may
exchange those shares back into a Dean Witter Multi-Class Fund or Global
Short-Term from the Exchange Fund, with no CDSC being imposed on such exchange.
The holding period previously frozen when shares were first exchanged for shares
of the Exchange Fund resumes on the last day of the month in which shares of a
Dean Witter Multi-Class Fund or of Global Short-Term are reacquired. A CDSC is
imposed only upon an ultimate redemption, based upon the time (calculated as
described above) the shareholder was invested in a Dean Witter Multi-Class Fund
or in Global Short-Term. 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 a FSC Fund.
    
 
   
    When shares initially purchased in a Dean Witter Multi-Class Fund or in
Global Short-Term are exchanged for shares of a Dean Witter Multi-Class Fund,
shares of Global Short-Term, shares of a FSC Fund, or shares of an Exchange
Fund, the date of purchase of the shares of the fund exchanged into, for
purposes of the CDSC upon redemption, will be the last day of the month in which
the shares being exchanged were originally purchased. In allocating the purchase
payments between funds for purposes of the CDSC, the amount which represents the
current net asset value of shares at the time of the exchange which were (i)
purchased more than one, three or six years (depending on the CDSC schedule
applicable to the shares) prior to the exchange, (ii) originally acquired
through reinvestment of dividends or distributions and (iii) acquired in
exchange for shares of FSC Funds, or for shares of other Dean Witter Funds for
which shares of FSC Funds have been exchanged (all such shares called "Free
Shares"), will be exchanged first. After an exchange, all dividends earned on
shares in an Exchange Fund will be considered Free Shares. If the exchanged
amount exceeds the value of such Free Shares, an exchange is made, on a
block-by-block basis, of non-Free Shares held for the longest period of time
(except that, with respect to Class B shares, if shares held for identical
periods of time but subject to different CDSC schedules are held in the same
Exchange Privilege account, the shares of that block that are subject to a lower
CDSC rate will be exchanged prior to the shares of that block that are subject
to a higher CDSC rate). Shares equal to any appreciation in the value of
non-Free Shares exchanged will be treated as Free Shares, and the amount of the
purchase payments for the non-Free Shares of the fund exchanged into will be
equal to the lesser of (a) the purchase payments for, or (b) the current net
asset value of, the exchanged non-Free Shares. If an exchange between funds
would result in exchange of only part of a particular block of non-Free Shares,
then shares equal to any appreciation in the value of the block (up to the
amount of the exchange) will be treated as Free Shares and exchanged first, and
the
    
 
                                       36
<PAGE>
purchase payment for that block will be allocated on a pro rata basis between
the non-Free Shares of that block to be retained and the non-Free Shares to be
exchanged. The prorated amount of such purchase payment attributable to the
retained non-Free Shares will remain as the purchase payment for such shares,
and the amount of purchase payment for the exchanged non-Free Shares will be
equal to the lesser of (a) the prorated amount of the purchase payment for, or
(b) the current net asset value of, those exchanged non-Free Shares. Based upon
the procedures described in the Prospectus under the caption "Purchase of Fund
Shares," any applicable CDSC will be imposed upon the ultimate redemption of
shares of any fund, regardless of the number of exchanges since those shares
were originally purchased.
 
    With respect to the redemption or repurchase of shares of the Fund, the
application of proceeds to the purchase of new shares in the Fund or any other
of the funds and the general administration of the Exchange Privilege, the
Transfer Agent acts as agent for the Distributor and for the shareholder's
selected broker-dealer, if any, in the performance of such functions. With
respect to exchanges, redemptions or repurchases, the Transfer Agent shall be
liable for its own negligence and not for the default or negligence of its
correspondents or for losses in transit. The Fund shall not be liable for any
default or negligence of the Transfer Agent, the Distributor or any selected
broker-dealer.
 
    The Distributor and any selected broker-dealer have authorized and appointed
the Transfer Agent to act as their agent in connection with the application of
proceeds of any redemption of Fund shares to the purchase of shares of any other
fund and the general administration of the Exchange Privilege. No commission or
discounts will be paid to the Distributor or any selected broker-dealer for any
transactions pursuant to this Exchange Privilege.
 
    Exchanges are subject to the minimum investment requirement and any other
conditions imposed by each fund. (The minimum initial investment for the
Exchange Privilege account of each Class is $5,000 for Dean Witter Liquid Asset
Fund Inc., Dean Witter Tax-Free Daily Income Trust, Dean Witter California Tax-
Free Daily Income Trust and Dean Witter New York Municipal Money Market Trust,
although those funds may, in their discretion, accept initial investments of as
low as $1,000. The minimum initial investment for the Exchange Privilege account
of each Class is $10,000 for Dean Witter Short-Term U.S. Treasury Trust,
although that fund, in its discretion, may accept initial purchases of as low as
$5,000. The minimum initial investment for the Exchange Privilege account of
each Class is $5,000 for Dean Witter Special Value Fund. The minimum initial
investment for the Exchange Privilege account of each Class of all other Dean
Witter Funds for which the Exchange Privilege is available is $1,000.) Upon
exchange into an Exchange Fund, the shares of that fund will be held in a
special Exchange Privilege Account separately from accounts of those
shareholders who have acquired their shares directly from that fund. As a
result, certain services normally available to shareholders of those funds,
including the check writing feature, will not be available for funds held in
that account.
 
    The Fund and each of the other Dean Witter Funds may limit the number of
times this Exchange Privilege may be exercised by any investor within a
specified period of time. Also, the Exchange Privilege may be terminated or
revised at any time by the Fund and/or any of the Dean Witter funds for which
shares of the Fund have been exchanged, upon such notice as may be required by
applicable regulatory agencies (presently sixty days' prior written notice for
termination or material revision), provided that six months' prior written
notice of termination will be given to the shareholders who hold shares of
Exchange Funds pursuant to the Exchange Privilege, and provided further that the
Exchange Privilege may be terminated or materially revised without notice at
times (a) when the New York Stock Exchange is closed for other than customary
weekends and holidays, (b) when trading on that Exchange is restricted, (c) when
an emergency exists as a result of which disposal by the Fund of securities
owned by it is not reasonably practicable or it is not reasonably practicable
for the Fund fairly to determine the value of its net assets, (d) during any
other period when the Securities and Exchange Commission by order so permits
(provided that applicable rules and regulations of the Securities and Exchange
Commission shall govern as to whether the conditions prescribed in (b) or (c)
exist) or (e) if the Fund would be unable to invest amounts effectively in
accordance with its investment objective, policies and restrictions.

should contact their DWR or other selected broker-dealer account executive or
the Transfer Agent.
 
REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 
   
    REDEMPTION.  As stated in the Prospectus, shares of each Class of the Fund
can be redeemed for cash at any time at the net asset value per share next
determined; however, such redemption proceeds will be reduced by the amount of
any applicable CDSC. 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, New Jersey 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. The share certificate, or an
accompanying stock power, and the request for redemption, must be signed by the
shareholder or shareholders exactly as the shares are registered. Each request
for redemption, whether or not accompanied by a share certificate, must be sent
to the Fund's Transfer Agent, which will redeem the shares at their net asset
value next computed (see "Purchase of Fund Shares" in the Prospectus) after it
receives the request, and certificate, if any, in good order. Any redemption
request received after such computation will be redeemed at the next determined
net asset value. The term "good order" means that the share certificate, if any,
and request for redemption are properly signed, accompanied by any documentation
required by the Transfer Agent, and bear signature guarantees when required by
the Fund or the Transfer Agent. If redemption is requested by a corporation,
partnership, trust or fiduciary, the Transfer Agent may require that written
evidence of authority acceptable to the Transfer Agent be submitted before such
request is accepted.
    
 
    Whether certificates are held by the shareholder or shares are held in a
shareholder's account, if the proceeds are to be paid to any person other than
the record owner, or if the proceeds are to be paid to a corporation (other than
the Distributor or a selected broker-dealer for the account of the shareholder),
partnership, trust or fiduciary, or sent to the shareholder at an address other
than the registered address, signatures must be guaranteed by an eligible
guarantor acceptable to the Transfer Agent (shareholders should contact the
Transfer Agent for a determination as to whether a particular institution is
such an eligible guarantor). A stock power may be obtained from any dealer or
commercial bank. The Fund may change the signature guarantee requirements from
time to time upon notice to shareholders, which may be by means of a supplement
to the prospectus or a revised prospectus.
 
    REPURCHASE.  As stated in the Prospectus, 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 computed after
such purchase order is received by DWR or other selected broker-dealer reduced
by any applicable CDSC.
 
   
    PAYMENT FOR SHARES REDEEMED OR REPURCHASED.  As discussed in the Prospectus,
payment for shares of any Class 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 (a) when the New York Stock
Exchange is closed for other than customary weekends and holidays, (b) when
trading on that Exchange is restricted, (c) when an emergency exists as a result
of which disposal by the Fund of securities owned by it is not reasonably
practicable or it is not reasonably practicable for the Fund fairly to determine
the value of its net assets, or (d) during any other period when the Securities
and Exchange Commission by order so permits; provided that applicable rules and
regulations of the Securities and Exchange Commission shall govern as to whether
the conditions prescribed in (b) or (c) exist. If the shares to be redeemed have
recently been purchased by check (including a certified or bank cashier's
check), payment of 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 proceeds of the check by the
Transfer Agent). It has been and remains the Fund's policy and practice
    
 
                                       38
<PAGE>
   
that, if checks for redemption proceeds remain uncashed, no interest will accrue
on amounts represented by such uncashed checks. Shareholders maintaining margin
accounts with DWR or another selected broker-dealer are referred to their
account executives regarding restrictions on redemption of shares of the Fund
pledged in the margin account.
    
 
    TRANSFERS OF SHARES.  In the event a shareholder requests a transfer of any
shares to a new registration, such shares will be transferred without sales
charge at the time of transfer. With regard to the status of shares which are
either subject to a CDSC or free of such charge (and with regard to the length
of time shares subject to the charge have been held), any transfer involving
less than all of the shares in an account will be made on a pro rata basis (that
is, by transferring shares in the same proportion that the transferred shares
bear to the total shares in the account immediately prior to the transfer). The
transferred shares will continue to be subject to any applicable CDSC as if they
had not been so transferred.
 
    REINSTATEMENT PRIVILEGE.  As discussed in the Prospectus, a shareholder who
has had his or her shares redeemed or repurchased and has not previously
exercised this reinstatement privilege may, within 35 days after 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 at the net asset value
next determined after a reinstatement request, together with the proceeds, is
received by the Transfer Agent.
 
    Exercise of the reinstatement privilege will not affect the federal income
tax treatment of any gain or loss realized upon the redemption or repurchase,
except that if the redemption or repurchase resulted in a loss and reinstatement
is made in shares of the Fund, some or all of the loss, depending on the amount
reinstated, will not be allowed as a deduction for federal income tax purposes
but will be applied to adjust the cost basis of the shares acquired upon
reinstatement.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
    As stated in the Prospectus, the Fund intends to distribute all of its net
investment income and all of its net short-term capital gains, if any, and will
determine whether to retain all or part of any net long-term capital gains.
 
    As discussed in the Prospectus, the Fund may invest a portion of its assets
in certain "private activity bonds" issued after August 7, 1986. As a result, a
portion of the exempt-interest dividends paid by the Fund may be an item of tax
preference to shareholders subject to the federal alternative minimum tax.
Certain corporations which are subject to the alternative minimum tax may also
have to include a portion of 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.
 
    Each shareholder will be sent at least a quarterly summary of his or her
account, including information as to reinvested dividends and capital gains
distributions. Share certificates for dividends or distributions will not be
issued unless a shareholder requests in writing that a certificate be issued for
a specific number of shares.
 
    In computing interest income, the Fund will amortize any premiums and
original issue discounts on securities owned. Capital gains or losses realized
upon sale or maturity of such securities will be based on their amortized cost.
 
   
    Gains or losses on the sales of securities by the Fund will be long-term
capital gains or losses if the securities have been held by the Fund for more
than twelve months. The Taxpayer Relief Act of 1997 reduced the maximum tax on
long-term capital gains from 28% to 20%; however, it also lengthened the
required holding period to obtain this lower rate from more than 12 months to
more than 18 months. These lower rates do not apply to collectibles and certain
other assets. Additionally, the maximum capital gain rate for assets that are
held more than five years and that are acquired after December 31, 2000 is 18%.
Gains or losses on the sale of securities held for twelve months or less will be
short-term capital gains or losses. Gains and losses on the sale, expiration or
other termination of options on securities will generally be treated as gains
and losses from the sale of securities. Pursuant to present federal income
    
 
                                       39
<PAGE>
tax laws, futures contracts held by the Fund at the end of each fiscal year will
be required to be "marked to market", that is, treated as having been sold at
their fair market value at such date. Sixty percent of any gain or loss
recognized on these deemed sales will be treated as long-term capital gain or
loss, and the remainder will be treated as short-term capital gain or loss.
Gains or losses from options on futures and listed options on debt instruments
will similarily be treated as part short-term and part long-term capital gains
or losses, unless such gains or losses were incurred as part of a securities
"straddle," in which case the appropriate straddle rules of the Internal Revenue
Code (the "Code") would apply.
 
   
    Any dividends declared in the last quarter of any calendar year which are
paid in the following year prior to February 1 will be deemed received by the
shareholder in the prior calendar year.
    
 
   
    The Taxpayer Relief Act of 1997 reduced the maximum tax on long-term capital
gains from 28% to 20%; however, it also lengthened the required holding period
to obtain this lower rate from more than 12 months to more than 18 months. These
lower rates do not apply to collectibles and certain other assets. Additionally,
the maximum capital gain rate for assets that are held more than five years and
that are acquired after December 31, 2000 is 18%.
    
 
    With respect to the Fund's investments in zero coupon bonds, the Fund
accrues income prior to any actual cash payments by their issuers. In order to
continue to comply with Subchapter M of the Code and remain able to forego
payment of Federal income tax on its income and capital gains, the Fund must
distribute all of its net investment income, including income accrued from zero
coupon bonds. As such, the Fund may be required to dispose of some of its
portfolio securities under disadvantageous circumstances to generate the cash
required for distribution.
 
   
    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.
    
 
    As discussed in the Prospectus, the Fund intends to continue 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. An exempt-interest dividend is that part
of dividend distributions made by the Fund which consists of interest received
by the Fund on tax-exempt securities upon which the shareholder incurs no
federal income taxes.
 
   
    Within sixty days after the end of its fiscal year, the Fund will mail to
shareholders a statement indicating the percentage of the dividend distributions
for such fiscal year which constitutes exempt-interest dividends and the
percentage, if any, that is taxable, and the percentage, if any, of the
exempt-interest dividends which constitutes an item of tax preference, and to
what extent the taxable portion is long-term capital gain, short-term capital
gain or ordinary income. These percentages should be applied uniformly to all
monthly distributions made during the fiscal year to determine the proportion of
dividends that is tax-exempt. The percentages may differ from the percentage of
tax-exempt dividend distributions for any particular month. 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 be subject to federal income tax on dividends paid from
interest income derived from taxable securities and on distributions of net
short-term capital gains. Such dividends and distributions are taxable to the
shareholder as ordinary dividend income regardless of whether the shareholder
receives such distributions in additional shares or in cash. Distributions of
long-term capital gains, if any, are taxable as long-term gains, regardless of
how long the shareholder has held Fund shares and whether the distribution is
received in additional shares or in cash. Since the Fund's income is expected to
be derived entirely from interest rather than dividends, none of such dividend
distributions will be eligible for the 70% dividends received deduction
generally available to corporations. Net long-term capital gains distributions
are not eligible for the dividends received deduction.
 
                                       40
<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 dividends paid with respect to such shares. Treasury Regulations
may provide for a reduction in such required holding period. If a shareholder
receives a distribution that is taxed as 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 to the extent of the capital gains
distribution.
 
    Interest on indebtedness incurred or continued by a shareholder to purchase
or carry shares of the Fund is not deductible to the extent allocable to
exempt-interest dividends of the Fund (which allocation does not take into
account capital gain dividends of the Fund). Furthermore, entities or persons
who are "substantial users" (or related persons) of facilities financed by
industrial development bonds should consult their tax advisers before purchasing
shares of the Fund. "Substantial user" is defined generally by Income Tax
Regulation 1.103-11 (b) as including a "non-exempt person" who regularly uses in
a trade or business a part of a facility financed from the proceeds of
industrial development bonds.
 
    From time to time, proposals have been introduced before Congress for the
purpose of restricting or eliminating the federal income tax exemption for
interest on municipal securities. It can be expected that similar proposals may
be introduced in the future. If such a proposal were enacted, the availability
of municipal securities for investment by the Fund could be affected. In such
event, the Fund would re-evaluate its investment objective and policies.
 
    To the extent that dividends are derived from interest on New York
tax-exempt securities, such dividends will also be exempt from New York State
and City personal income taxes. Interest on indebtedness incurred or continued
to purchase or carry shares of an investment company paying exempt-interest
dividends, such as the Fund, may not be deductible by the investor for State or
City personal income tax purposes.
 
    The foregoing relates to federal income taxation and to New York State and
City personal income taxation as in effect as of the date of the Prospectus.
Distributions from investment income and capital gains, including
exempt-interest dividends, may be subject to New York franchise taxes if
received by a corporation doing business in New York, to state taxes in states
other than New York and to local taxes.
 
    The Fund is organized as a Massachusetts business trust. Under current law,
so long as it qualifies as a "regulated investment company" under the Internal
Revenue Code, the Fund itself is not liable for any income or franchise tax in
The Commonwealth of Massachusetts.
 
    Any dividend or capital gains distribution received by a shareholder from
any investment company will have the effect of reducing the net asset value of
the shareholder's stock in that fund by the exact amount of the dividend or
capital gains distribution. Furthermore, capital gains distributions are, and
some portion of the dividends may be, subject to income tax. If the net asset
value of the shares should be reduced below a shareholder's cost as a result of
the payment of taxable dividends or the distribution of realized long-term
capital gains, such payment or distribution, in effect, would be a return of
capital but nonetheless taxable at ordinary rates. Therefore, an investor should
consider the tax implications of purchasing Fund shares immediately prior to a
distribution record date.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
    As discussed in the Prospectus, 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. Yield is calculated for any 30-day period as follows: the amount of
interest income for each security in the Fund's portfolio is determined in
accordance with regulatory requirements; the total for the entire portfolio
constitutes the Fund's gross income for the period. Expenses accrued during the
period are subtracted to arrive at "net investment income" of each Class. The
resulting amount is divided by the product of the maximum offering price per
share on the last day of the period multiplied by the average number of shares
of the applicable Class outstanding during the period that were entitled to
dividends. This amount is added to 1 and raised to the sixth power. 1 is then
 
                                       41
<PAGE>
   
subtracted from the result and the difference is multiplied by 2 to arrive at
the annualized yield. The yields for the 30-day period ended December 31, 1997,
calculated pursuant to the formula described above, were 3.96%, 3.64%, 3.63% and
4.40% for Class A, Class B, Class C and Class D, respectively.
    
 
   
    The Fund may also quote a "tax-equivalent yield" determined by dividing the
tax-exempt portion of the quoted yield by 1 minus the stated income tax rate and
adding the result to the portion of the yield that is not tax-exempt. The Fund's
tax-equivalent yield, based upon a combined Federal and New York State personal
income tax bracket of 44.70% (the highest current individual marginal tax rate),
for the 30-day period ending December 31, 1997, were 7.16%, 6.58%, 6.56% and
7.96%, respectively based upon the yields quoted above.
    
 
   
    The Fund's "average annual total return" represents an annualization of the
Fund's total return over a specified period and is computed by finding the
annual percentage rate which will result in the ending redeemable value of a
hypothetical $1,000 investment made at the beginning of a one, five or ten year
period, or for the period from the date of commencement of the Fund's
operations, if shorter than any of the foregoing. The ending redeemable value is
reduced by any CDSC at the end of the one, five or ten year or other period. For
the purpose of this calculation, it is assumed that all dividends and
distributions are reinvested. The formula for computing the average annual total
return involves a percentage obtained by dividing the ending redeemable value by
the amount of the initial investment, taking a root of the quotient (where the
root is equivalent to the number of the years in the period) and subtracting 1
from the result. The average annual total returns of Class B for the one, five
and ten year periods ended December 31, 1997 were 3.43%, 5.71% and 7.57%,
respectively.
    
 
   
    For periods of less than one year, the Fund quotes its total return on a
non-annualized basis. Accordingly, the Fund may compute its aggregate total
return for each of Class A, Class C and Class D for specified periods by
determining the aggregate percentage rate which will result in the ending value
of a hypothetical $1,000 investment made at the beginning of the period. For the
purpose of this calculation, it is assumed that all dividends and distributions
are reinvested. The formula for computing aggregate total return involves a
percentage obtained by dividing the ending value by the initial $1,000
investment and subtracting 1 from the result. The ending redeemable value is
reduced by any CDSC at the end of the period. Based on the foregoing
calculations, the total returns for the period July 28, 1997 through December
31, 1997 were -1.15%, 1.83% and 3.27% for Class A, Class C and Class D,
respectively.
    
 
   
    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 imposition of the maximum front-end sales charge for Class A
or the deduction of the CDSC for each of Class B and Class C which, if
reflected, would reduce the performance quoted. For example, the average annual
total return of the Fund may be calculated in the manner described in the
preceding paragraph, but without deduction for any applicable sales charge.
Based on this calculation, the average annual total returns of Class B for the
one, five and ten year periods ended December 31, 1997 were 8.43%, 6.02% and
7.57%, respectively.
    
 
   
    In addition, the Fund may compute its aggregate total return for each Class
for specified periods by determining the aggregate percentage rate which will
result in the ending value of a hypothetical $1,000 investment made at the
beginning of the period. For the purpose of this calculation, it is assumed that
all dividends and distributions are reinvested. The formula for computing
aggregate total return involves a percentage obtained by dividing the ending
value (without reduction for any sales charge) by the initial $1,000 investment
and subtracting 1 from the result. Based on the foregoing calculation, the total
returns of Class B for the one, five and ten year periods ended December 31,
1997 were 8.43%, 33.97% and 107.45%, respectively. Based on the foregoing
calculations, the total returns for Class A, Class C and Class D for the period

DESCRIPTION OF SHARES OF THE FUND
- --------------------------------------------------------------------------------
 
   
    The shareholders of the Fund are entitled to a full vote for each full share
held. All of the Trustees have been elected by the shareholders of the Fund,
most recently at a Special Meeting of Shareholders held on May 21, 1997. The
Trustees themselves have the power to alter the number and the terms of office
of the Trustees, and they may at any time lengthen their own terms or make their
terms of unlimited duration and appoint their own successors, provided that
always at least a majority of the Trustees has been elected by the shareholders
of the Fund. Under certain circumstances the Trustees may be removed by action
of the Trustees. The shareholders also have the right under certain
circumstances to remove the Trustees. The voting rights of shareholders are not
cumulative, so that holders of more than 50 percent of the shares voting can, if
they choose, elect all Trustees being selected, while the holders of the
remaining shares would be unable to elect any Trustees.
    
 
    The Declaration of Trust permits the Trustees to authorize the creation of
additional series of shares (the proceeds of which would be invested in
separate, independently managed portfolios) and additional classes of shares
within any series. The Trustees have not authorized any such additional series
or classes of shares other than as set forth in the Prospectus.
 
    The Declaration of Trust provides that no Trustee, officer, employee or
agent of the Fund is liable to the Fund or to a shareholder, nor is any Trustee,
officer, employee or agent liable to any third persons in connection with the
affairs of the Fund, except as such liability may arise from his/her or its own
bad faith, willful misfeasance, gross negligence, or reckless disregard of
his/her or its duties. It also provides that all third persons shall look solely
to the Fund property for satisfaction of claims arising in connection with the
affairs of the Fund. With the exceptions stated above, the Declaration of Trust
provides that a Trustee, officer, employee or agent is entitled to be
indemnified against all liability in connection with the affairs of the Fund.
 
    The Fund is authorized to issue an unlimited number of shares of beneficial
interest. The Fund shall be of unlimited duration, subject to the provisions in
the Declaration of Trust concerning termination by action of the shareholders.

DEAN WITTER NEW YORK TAX-FREE INCOME FUND
REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND TRUSTEES
OF DEAN WITTER NEW YORK TAX-FREE INCOME FUND
 
In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Dean Witter New York Tax-Free
Income Fund (the "Fund") at December 31, 1997, the results of its operations for
the year then ended, the changes in its net assets for each of the two years in
the period then ended and the financial highlights for each of the periods
presented, in conformity with generally accepted accounting principles. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statements
presentation. We believe that our audits, which included confirmation of
securities at December 31, 1997 by correspondence with the custodian and
brokers, provide a reasonable basis for the opinion expressed above.

DEAN WITTER NEW YORK TAX-FREE INCOME FUND
NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1997
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter New York Tax-Free Income Fund (the "Fund") is registered under the
Investment Company Act of 1940, as amended (the "Act"), as a diversified,
open-end management investment company. The Fund's investment objective is to
provide a high level of current income which is exempt from federal, New York
State and New York City income tax, consistent with the preservation of capital.
The Fund was organized as a Massachusetts business trust on January 17, 1985 and
commenced operations on April 25, 1985. On July 28, 1997, the Fund commenced
offering three additional classes of shares, with the then current shares
designated as Class B shares.
 
The Fund offers Class A shares, Class B shares, Class C shares and Class D
shares. The four classes are substantially the same except that most Class A
shares are subject to a sales charge imposed at the time of purchase, some Class
A shares, and most Class B shares and Class C shares are subject to a contingent
deferred sales charge imposed on shares redeemed within one year, six years and
one year, respectively. Class D shares are not subject to a sales charge.
Additionally, Class A shares, Class B shares and Class C shares incur
distribution expenses.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual results could differ from
those estimates.
 
The following is a summary of significant accounting policies:
 
A. VALUATION OF INVESTMENTS --  Portfolio securities are valued for the Fund by
an outside independent pricing service approved by the Trustees. The pricing
service has informed the Fund that in valuing the Fund's portfolio securities,
it uses both a computerized matrix of tax-exempt securities and evaluations by
its staff, in each case based on information concerning market transactions and
quotations from dealers which reflect the bid side of the market each day. The
Fund's portfolio securities are thus valued by reference to a combination of
transactions and quotations for the same or other securities believed to be
comparable in quality, coupon, maturity, type of issue, call provisions, trading
characteristics and other features deemed to be relevant. Short-term debt
securities having a maturity date of more than sixty days at time of purchase
are valued on a mark-to-market basis until sixty days prior to maturity and
thereafter at amortized cost based on their value on the 61st day. Short-term
debt securities having a maturity date of sixty days or less at the time of
purchase are valued at amortized cost.

DEAN WITTER NEW YORK TAX-FREE INCOME FUND
NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1997, CONTINUED
 
B. ACCOUNTING FOR INVESTMENTS --  Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
The Fund amortizes premiums and accretes discounts over the life of the
respective securities. Interest income is accrued daily.
 
C. MULTIPLE CLASS ALLOCATIONS --  Investment income, expenses (other than
distribution fees), and realized and unrealized gains and losses are allocated
to each class of shares based upon the relative net asset value on the date such
items are recognized. Distribution fees are charged directly to the respective
class.
 
D. FEDERAL INCOME TAX STATUS --  It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable and nontaxable income to its
shareholders. Accordingly, no federal income tax provision is required.
 
E. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS --  The Fund records dividends
and distributions to its shareholders on the record date. The amount of
dividends and distributions from net investment income and net realized capital
gains are determined in accordance with federal income tax regulations which may
differ from generally accepted accounting principles. These "book/tax"
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the capital accounts based on their federal tax-basis treatment;
temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for financial reporting purposes but not for tax purposes are reported as
dividends in excess of net investment income or distributions in excess of net
realized capital gains. To the extent they exceed net investment income and net
realized capital gains for tax purposes, they are reported as distributions of
paid-in-capital.
 
2. INVESTMENT MANAGEMENT AGREEMENT
 
Pursuant to an Investment Management Agreement with Dean Witter InterCapital
Inc. (the "Investment Manager"), the Fund pays the Investment Manager a
management fee, accrued daily and payable monthly, by applying the following
annual rates to the Fund's net assets determined as of the close of each
business day: 0.55% to the portion of daily net assets not exceeding $500
million and 0.525% to the portion of daily net assets exceeding $500 million.

Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes, at its own expense, office space, facilities, equipment,
clerical, bookkeeping and certain legal services and pays the salaries of all
personnel, including officers of the Fund who are employees of the Investment
Manager. The Investment Manager also bears the cost of telephone services, heat,
light, power and other utilities provided to the Fund.
 
3. PLAN OF DISTRIBUTION
 
Shares of the Fund are distributed by Dean Witter Distributors Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Fund has adopted a
Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the Act. The Plan
provides that the Fund will pay the Distributor a fee which is accrued daily and
paid monthly at the following annual rates: (i) Class A -- up to 0.25% of the
average daily net assets of Class A; (ii) Class B -- 0.75% of the lesser of: (a)
the average daily aggregate gross sales of the Class B shares since the
inception of the Fund (not including reinvestment of dividend or capital gain
distributions) less the average daily aggregate net asset value of the Class B
shares redeemed since the Fund's inception upon which a contingent deferred
sales charge has been imposed or waived; or (b) the average daily net assets of
Class B; and (iii) Class C -- up to 0.75% of the average daily net assets of
Class C. In the case of Class A shares, amounts paid under the Plan are paid to
the Distributor for services provided. In the case of Class B and Class C
shares, amounts paid under the Plan are paid to the Distributor for services
provided and the expenses borne by it and others in the distribution of the
shares of these Classes, including the payment of commissions for sales of these
Classes and incentive compensation to, and expenses of, the account executives
of Dean Witter Reynolds Inc. ("DWR"), an affiliate of the Investment Manager and
Distributor, and others who engage in or support distribution of the 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 these 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.
 
In the case of Class B shares, provided that the Plan continues in effect, any
cumulative expenses incurred by the Distributor but not yet recovered may be
recovered through the payment of future distribution fees from the Fund pursuant
to the Plan and contingent deferred sales charges paid by

investors upon redemption of Class B shares. Although there is no legal
obligation for the Fund to pay expenses incurred in excess of payments made to
the Distributor under the Plan and the proceeds of contingent deferred sales
charges paid by investors upon redemption of shares, if for any reason the Plan
is terminated, the Trustees will consider at that time the manner in which to
treat such expenses. The Distributor has advised the Fund that such excess
amounts, including carrying charges, totaled $1,970,148 at December 31, 1997.
 
In the case of Class A shares and Class C shares, expenses incurred pursuant to
the Plan in any calendar year in excess of 0.25% or 0.75% of the average daily
net assets of Class A or Class C, respectively, will not be reimbursed by the
Fund through payments in any subsequent year, except that expenses representing
a gross sales credit to account executives may be reimbursed in the subsequent
calendar year. For the period ended December 31, 1997, the distribution fee was
accrued for Class A shares and Class C shares at the annual rate of 0.25% and
0.75%, respectively.
 
The Distributor has informed the Fund that for the year ended December 31, 1997,
it received contingent deferred sales charges from certain redemptions of the
Fund's Class B shares of $281,986 and received $993 in front-end sales charges
from sales of the Fund's Class A shares. The respective shareholders pay such
charges, which are not an expense of the Fund.
 
4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES
 
The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the year ended December 31, 1997 aggregated
$17,042,682 and $37,661,135, respectively.
 
Dean Witter Trust FSB, an affiliate of the Investment Manager and Distributor,
is the Fund's transfer agent. At December 31, 1997, the Fund had transfer agent
fees and expenses payable of approximately $3,300.
 
The Fund has an unfunded noncontributory defined benefit pension plan covering
all independent Trustees of the Fund who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on years of service and compensation during the last five years
of service. Aggregate pension costs for the year ended December 31, 1997
included in Trustees' fees and expenses in the Statement of Operations amounted
to $2,720. At December 31, 1997, the Fund had an accrued pension liability of
$48,294 which is included in accrued expenses in the Statement of Assets and
Liabilities.

RATINGS OF INVESTMENTS
MOODY'S INVESTORS SERVICE INC. ("MOODY'S")
                             MUNICIPAL BOND RATINGS
 
Aaa   Bonds which are rated Aaa are judged to be of the best quality. They carry
      the smallest degree of investment risk and are generally referred to as
      "gilt edge." Interest payments are protected by a large or by an
      exceptionally stable margin and principal is secure. While the various
      protective elements are likely to change, such changes as can be
      visualized are most unlikely to impair the fundamentally strong position
      of such issues.
 
Aa    Bonds which are Aa are judged to be of high quality by all standards.
      Together with the Aaa group they comprise what are generally known as high
      grade bonds. They are rated lower than the best bonds because margins of
      protection may not be as large as in Aaa securities or fluctuation of
      protective elements may be of greater amplitude or there may be other
      elements present which make the long-term risks appear somewhat larger
      than in Aaa securities.
 
A     Bonds which are rated A possess many favorable investment attributes and
      are to be considered as upper medium grade obligations. Factors giving
      security to principal and interest are considered adequate, but elements
      may be present which suggest a susceptibility to impairment sometime in
      the future.
 
Baa   Bonds which are rated Baa are considered as medium grade obligations;
      i.e., they are neither highly protected nor poorly secured. Interest
      payments and principal security appear adequate for the present but
      certain protective elements may be lacking or may be characteristically
      unreliable over any great length of time. Such bonds lack outstanding
      investment characteristics and in fact have speculative characteristics as
      well.
 
      Bonds rated Aaa, Aa, A and Baa are considered investment grade bonds.
 
Ba    Bonds which are rated Ba are judged to have speculative elements; their
      future cannot be considered as well assured. Often the protection of
      interest and principal payments may be very moderate, and therefore not
      well safeguarded during both good and bad times in the future. Uncertainty
      of position characterizes bonds in this class.
 
B     Bonds which are rated B generally lack characteristics of the desirable
      investment. Assurance of interest and principal payments or of maintenance
      of other terms of the contract over any long period of time may be small.
 
Caa   Bonds which are rated Caa are of poor standing. Such issues may be in
      default or there may be present elements of danger with respect to
      principal or interest.
 
Ca    Bonds which are rated Ca present obligations which are speculative in a
      high degree. Such issues are often in default or have other marked
      shortcomings.
 
C     Bonds which are rated C are the lowest rated class of bonds, and issues so
      rated can be regarded as having extremely poor prospects of ever attaining
      any real investment standing.
 
    CONDITIONAL RATING:  Bonds for which the security depends upon the
completion of some act or the fulfillment of some condition are rated
conditionally. These bonds secured by (a) earnings of projects under
construction, (b) earnings of projects unseasoned in operation experience, (c)
rentals which begin when facilities are completed or (d) payments to which some
other limiting condition attaches. Parenthetical rating denotes probable credit
stature upon completion of construction or elimination of basis of condition.
 
    RATING REFINEMENTS:  Moody's may apply numerical modifiers, 1, 2, and 3 in
each generic rating classification from Aa through B in its municipal bond
rating system. The modifier 1 indicates that the security ranks in the higher
end of its generic rating category; the modifier 2 indicates a mid-range
ranking; and a modifier 3 indicates that the issue ranks in the lower end of its
generic rating category.

                             MUNICIPAL NOTE RATINGS
 
    Moody's ratings for state and municipal note and other short-term loans are
designated Moody's Investment Grade (MIG). MIG 1 denotes best quality and means
there is present strong protection from established cash flows, superior
liquidity support or demonstrated broad-based access to the market for
refinancing. MIG 2 denotes high quality and means that margins of protection are
ample although not as large as in MIG 1. MIG 3 denotes favorable quality and
means that all security elements are accounted for but that the undeniable
strength of the previous grades, MIG 1 and MIG 2, is lacking. MIG 4 denotes
adequate quality and means that the protection commonly regarded as required of
an investment security is present and that while the notes are not distinctly or
predominantly speculative, there is specific risk.
 
                        VARIABLE RATE DEMAND OBLIGATIONS
 
    A short-term rating, in addition to the Bond or MIG ratings, designated VMIG
may also be assigned to an issue having a demand feature. The assignment of the
VMIG symbol reflects such characteristics as payment upon periodic demand rather
than fixed maturity dates and payment relying on external liquidity. The VMIG
rating criteria are identical to the MIG criteria discussed above.
 
                            COMMERCIAL PAPER RATINGS
 
    Moody's Commercial Paper ratings are opinions of the ability to repay
punctually promissory obligations not having an original maturity in excess of
nine months. These ratings apply to Municipal Commercial Paper as well as
taxable Commercial Paper. Moody's employs the following three designations, all
judged to be investment grade, to indicate the relative repayment capacity of
rated issuers: Prime-1, Prime-2, Prime-3.
 
    Issuers rated Prime-1 have a superior capacity for repayment of short-term
promissory obligations. Issuers rated Prime-2 have a strong capacity for
repayment of short-term promissory obligations; and Issuers rated Prime-3 have
an acceptable capacity for repayment of short-term promissory obligations.
Issuers rated Not Prime do not fall within any of the Prime rating categories.
 
STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S")
 
                             MUNICIPAL BOND RATINGS
 
    A Standard & Poor's municipal bond rating is a current assessment of the
creditworthiness of an obligor with respect to a specific obligation. This
assessment may take into consideration obligors such as guarantors, insurers or
lessees.
 
    The ratings are based on current information furnished by the issuer or
obtained by Standard & Poor's from other sources it considers reliable. The
ratings are based, in varying degrees, on the following considerations: (1)
likelihood of default-capacity and willingness of the obligor as to the timely
payment of interest and repayment of principal in accordance with the terms of
the obligation; (2) nature of and provisions of the obligation; and (3)
protection afforded by, and relative position of the obligation in the event of
bankruptcy, reorganization or other arrangement under the laws of bankruptcy and
other laws affecting creditors' rights.
 
    Standard & Poor's does not perform an audit in connection with any rating
and may, on occasion, rely on unaudited financial information. The ratings may
be changed, suspended or withdrawn as a result of changes in, or unavailability
of, such information, or for other reasons.
 
AAA   Debt rated "AAA" has the highest rating assigned by Standard & Poor's.
      Capacity to pay interest and repay principal is extremely strong.
 
AA    Debt rated "AA" has a very strong capacity to pay interest and repay
      principal and differs from the highest-rated issues only in small degree.
 
                                       61
<PAGE>
A     Debt rated "A" has a strong capacity to pay interest and repay principal
      although they are somewhat more susceptible to the adverse effects of
      changes in circumstances and economic conditions than debt in higher-rated
      categories.
 
BBB   Debt rated "BBB" is regarded as having an adequate capacity to pay
      interest and repay principal. Whereas it normally exhibits adequate
      protection parameters, adverse economic conditions or changing
      circumstances are more likely to lead to a weakened capacity to pay
      interest and repay principal for debt in this category than for debt in
      higher-rated categories.
 
      Bonds rated AAA, AA, A and BBB are considered investment grade bonds.
 
BB    Debt rated "BB" has less near-term vulnerability to default than other
      speculative grade debt. However, it faces major ongoing uncertainties or
      exposure to adverse business, financial or economic conditions which would
      lead to inadequate capacity or willingness to pay interest and repay
      principal.
 
B     Debt rated "B" has a greater vulnerability to default but presently has
      the capacity to meet interest payments and principal repayments. Adverse
      business, financial or economic conditions would likely impair capacity or
      willingness to pay interest and repay principal.
 
CCC   Debt rated "CCC" has a current identifiable vulnerability to default, and
      is dependent upon favorable business, financial and economic conditions to
      meet timely payments of interest and repayments of principal. In the event
      of adverse business, financial or economic conditions, it is not likely to
      have the capacity to pay interest and repay principal.
 
CC    The rating "CC" is typically applied to debt subordinated to senior debt
      which is assigned an actual or implied "CCC" rating.
 
C     The rating "C" is typically applied to debt subordinated to senior debt
      which is assigned an actual or implied "CCC-" debt rating.
 
CI    The rating "CI" is reserved for income bonds on which no interest is being
      paid.
 
D     Debt rated "D" is in payment default. The 'D' rating category is used when
      interest payments or principal payments are not made on the date due even
      if the applicable grace period has not expired, unless S&P believes that
      such payments will be made during such grace period. The 'D' rating also
      will be used upon the filing of a bankruptcy petition if debt service
      payments are jeopardized.
 
NR    Indicates that no rating has been requested, that there is insufficient
      information on which to base a rating or that Standard & Poor's does not
      rate a particular type of obligation as a matter of policy.
 
      Bonds rated "BB", "B", "CCC", "CC" and "C" are regarded as having
      predominantly speculative characteristics with respect to capacity to pay
      interest and repay principal. "BB" indicates the least degree of
      speculation and "C" the highest degree of speculation. While such debt
      will likely have some quality and protective characteristics, these are
      outweighed by large uncertainties or major risk exposures to adverse
      conditions.
 
      PLUS (+) OR MINUS (-):  The ratings from "AA" to "CCC" may be modified by
      the addition of a plus or minus sign to show relative standing with the
      major ratings categories.
 
    The foregoing ratings are sometimes followed by a "p" which indicates that
the rating is provisional. A provisional rating assumes the successful
completion of the project being financed by the bonds being rated and indicates
that payment of debt service requirements is largely or entirely dependent upon
the successful and timely completion of the project. This rating, however, while
addressing credit quality subsequent to completion of the project, makes no
comment on the likelihood or risk of default upon failure of such completion.

                             MUNICIPAL NOTE RATINGS
 
    Commencing on July 27, 1984, Standard & Poor's instituted a new rating
category with respect to certain municipal note issues with a maturity of less
than three years. The new note ratings denote the following:
 
    SP-1  denotes a very strong or strong capacity to pay principal and
          interest. Issues determined to possess overwhelming safety
          characteristics are given a plus (+) designation (SP-1+).
 
    SP-2  denotes a satisfactory capacity to pay principal and interest.
 
    SP-3  denotes a speculative capacity to pay principal and interest.
 
                            COMMERCIAL PAPER RATINGS
 
    Standard and Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days. The commercial paper rating is not a recommendation to purchase or
sell a security. The ratings are based upon current information furnished by the
issuer or obtained by Standard & Poor's from other sources it considers
reliable. The ratings may be changed, suspended or withdrawn as a result of
changes in or unavailability of such information. Ratings are graded into group
categories, ranging from "A" for the highest quality obligations to "D" for the
lowest. Ratings are applicable to both taxable and tax-exempt commercial paper.
The categories are as follows:
 
    Issuers assigned A ratings are regarded as having the greatest capacity for
timely payment. Issues in this category are further refined with the designation
1, 2 and 3 to indicate the relative degree of safety.
 
<TABLE>
<S>        <C>
A-1        indicates that the degree of safety regarding timely payment is very strong.
 
A-2        indicates capacity for timely payment on issues with this designation is strong.
           However, the relative degree of safety is not as overwhelming as for issues designated
           "A-1."
 
A-3        indicates a satisfactory capacity for timely payment. Obligations carrying this
           designation are, however, somewhat more vulnerable to the adverse effects of changes in
           circumstances than obligations carrying the higher designations.

Item 27.  INDEMNIFICATION

     Pursuant to Section 5.3 of the Registrant's Declaration of Trust and under
Section 4.8 of the Registrant's By-Laws, the indemnification of the Registrant's
trustees, officers, employees and agents is permitted if it is determined that
they acted under the belief that their actions were in or not opposed to the
best interest of the Registrant, and, with respect to any criminal proceeding,
they had reasonable cause to believe their conduct was not unlawful.  In
addition, indemnification is permitted only if it is determined that the actions
in question did not render them liable by reason of willful misfeasance, bad
faith or gross negligence in the performance of their duties or by reason of
reckless disregard of their obligations and duties to the Registrant.  Trustees,
officers, employees and agents will be indemnified for the expense of litigation
if it is determined that they are entitled to indemnification against any
liability established in such litigation.  The Registrant may also advance money
for these expenses provided that they give their undertakings to repay the
Registrant unless their conduct is later determined to permit indemnification.

<PAGE>

     Pursuant to Section 5.2 of the Registrant's Declaration of Trust and
paragraph 8 of the Registrant's Investment Management Agreement, neither the
Investment Manager nor any trustee, officer, employee or agent of the Registrant
shall be liable for any action or failure to act, except in the case of bad
faith, willful misfeasance, gross negligence or reckless disregard of duties to
the Registrant.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Act") may be permitted to trustees, officers and controlling
persons of the Registrant pursuant to the foregoing provisions or otherwise, the
Registrant has been advised that in the opinion of the  Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a trustee, officer, or controlling person of the Registrant
in connection with the successful defense of any action, suit or proceeding) is
asserted against the Registrant by such trustee, officer or controlling person
in connection with the shares being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act, and will
be governed by the final adjudication of such issue.

     The Registrant hereby undertakes that it will apply the indemnification
provision of its by-laws in a manner consistent with Release 11330 of the
Securities and Exchange Commission under the Investment Company Act of 1940, so
long as the interpretation of Sections 17(h) and 17(i) of such Act remains in
effect.

     Registrant, in conjunction with the Investment Manager, Registrant's
Trustees, and other registered investment management companies managed by the
Investment Manager, maintains insurance on behalf of any person who is or was a
Trustee, officer, employee, or agent of Registrant, or who is or was serving at
the request of Registrant as a trustee, director, officer, employee or agent of
another trust or corporation, against any liability asserted against him and
incurred by him or arising out of his position.  However, in no event will
Registrant maintain insurance to indemnify any such person for any act for which
Registrant itself is not permitted to indemnify him.

(25%) of all the votes entitled to be cast at such meeting. Such request 
shall state the purpose or purposes of such meeting and the matters proposed 
to be acted on thereat. The Secretary shall inform such Shareholders of the 
reasonable estimated cost of preparing and mailing such notice of the 
meeting, and upon payment to the Trust of such costs, the Secretary shall 
give notice stating the purpose or purposes of the meeting to all entitled to 
vote at such meeting. No meeting need be called upon the request of the 
holders of Shares entitled to cast less than a majority of all votes entitled 
to be cast at such meeting, to consider any matter which is substantially the 
same as a matter voted upon at any meeting of Shareholders held during the 
preceding twelve months. 

   SECTION 3.3. NOTICE OF MEETINGS. Written or printed notice of every 
Shareholders' meeting stating the place, date, and purpose or purposes 
thereof, shall be given by the Secretary not less than ten (10) nor more than 
ninety (90) days before such meeting to each Shareholder entitled to vote at 
such meeting. Such notice shall be deemed to be given when deposited in the 
United States mail, postage prepaid, directed to the Shareholder at his 
address as it appears on the records of the Trust. 

   SECTION 3.4 QUORUM AND ADJOURNMENT OF MEETINGS. Except as otherwise 
provided by law, by the Declaration or by these By-Laws, at all meetings of 
Shareholders, the holders of a majority of the Shares 

                                1           
<PAGE>
issued and outstanding and entitled to vote thereat, present in person or 
represented by proxy, shall be requisite and shall constitute a quorum for 
the transaction of business. In the absence of a quorum, the Shareholders 
present or represented by proxy and entitled to vote thereat shall have the 
power to adjourn the meeting from time to time. The Shareholders present in 
person or represented by proxy at any meeting and entitled to vote thereat 
also shall have the power to adjourn the meeting from time to time if the 
vote required to approve or reject any proposal described in the original 
notice of such meeting is not obtained (with proxies being voted for or 
against adjournment consistent with the votes for and against the proposal 
for which the required vote has not been obtained). The affirmative vote of 
the holders of a majority of the Shares then present in person or represented 
by proxy shall be required to adjourn any meeting. Any adjourned meeting may 
be reconvened without further notice or change in record date. At any 
reconvened meeting at which a quorum shall be present, any business may be 
transacted that might have been transacted at the meeting as originally 
called. 

   SECTION 3.5. VOTING RIGHTS, PROXIES. At each meeting of Shareholders, each 
holder of record of Shares entitled to vote thereat shall be entitled to one 
vote in person or by proxy, executed in writing by the Shareholder or his 
duly authorized attorney-in-fact, for each Share of beneficial interest of 
the Trust and for the fractional portion of one vote for each fractional 
Share entitled to vote so registered in his name on the records of the Trust 
on the date fixed as the record date for the determination of Shareholders 
entitled to vote at such meeting. No proxy shall be valid after eleven months 
from its date, unless otherwise provided in the proxy. At all meetings of 
Shareholders, unless the voting is conducted by inspectors, all questions 
relating to the qualification of voters and the validity of proxies and the 
acceptance or rejection of votes shall be decided by the chairman of the 
meeting. Pursuant to a resolution of a majority of the Trustees, proxies may 
be solicited in the name of one or more Trustees or Officers of the Trust. 

   SECTION 3.6. VOTE REQUIRED. Except as otherwise provided by law, by the 
Declaration of Trust, or by these By-Laws, at each meeting of Shareholders at 
which a quorum is present, all matters shall be decided by Majority 
Shareholder Vote. 

   SECTION 3.7. INSPECTORS OF ELECTION. In advance of any meeting of 
Shareholders, the Trustees may appoint Inspectors of Election to act at the 
meeting or any adjournment thereof. If Inspectors of Election are not so 
appointed, the chairman of any meeting of Shareholders may, and on the 
request of any Shareholder or his proxy shall, appoint Inspectors of Election 
of the meeting. In case any person appointed as Inspector fails to appear or 
fails or refuses to act, the vacancy may be filled by appointment made by the 
Trustees in advance of the convening of the meeting or at the meeting by the 
person acting as chairman. The Inspectors of Election shall determine the 
number of Shares outstanding, the Shares represented at the meeting, the 
existence of a quorum, the authenticity, validity and effect of proxies, 
shall receive votes, ballots or consents, shall hear and determine all 
challenges and questions in any way arising in connection with the right to 
vote, shall count and tabulate all votes or consents, determine the results, 
and do such other acts as may be proper to conduct the election or vote with 
fairness to all Shareholders. On request of the chairman of the meeting, or 
of any Shareholder or his proxy, the Inspectors of Election shall make a 
report in writing of any challenge or question or matter determined by them 
and shall execute a certificate of any facts found by them. 

   SECTION 3.8. INSPECTION OF BOOKS AND RECORDS. Shareholders shall have such 
rights and procedures of inspection of the books and records of the Trust as 
are granted to Shareholders under the Corporations and Associations Law of 
the State of Maryland. 

   SECTION 3.9. ACTION BY SHAREHOLDERS WITHOUT MEETING. Except as otherwise 
provided by law, the provisions of these By-Laws relating to notices and 
meetings to the contrary notwithstanding, any action required or permitted to 
be taken at any meeting of Shareholders may be taken without a meeting if a 
majority of the Shareholders entitled to vote upon the action consent to the 
action in writing and such consents are filed with the records of the Trust. 
Such consent shall be treated for all purposes as a vote taken at a meeting 
of Shareholders. 

   SECTION 3.10. PRESENCE AT MEETINGS. Presence at meetings of shareholders 
requires physical attendance by the shareholder or his or her proxy at the 
meeting site and does not encompass attendance by telephonic or other 
electronic means.

                                   TRUSTEES 

   SECTION 4.1. MEETINGS OF THE TRUSTEES. The Trustees may in their 
discretion provide for regular or special meetings of the Trustees. Regular 
meetings of the Trustees may be held at such time and place as shall be 
determined from time to time by the Trustees without further notice. Special 
meetings of the Trustees may be called at any time by the President and shall 
be called by the President or the Secretary upon the written request of any 
two (2) Trustees. 

   SECTION 4.2. NOTICE OF SPECIAL MEETINGS. Written notice of special 
meetings of the Trustees, stating the place, date and time thereof, shall be 
given not less than two (2) days before such meeting to each Trustee, 
personally, by telegram, by mail, or by leaving such notice at his place of 
residence or usual place of business. If mailed, such notice shall be deemed 
to be given when deposited in the United States mail, postage prepaid, 
directed to the Trustee at his address as it appears on the records of the 
Trust. Subject to the provisions of the 1940 Act, notice or waiver of notice 
need not specify the purpose of any special meeting. 

   SECTION 4.3. TELEPHONE MEETINGS. Subject to the provisions of the 1940 
Act, any Trustee, or any member or members of any committee designated by the 
Trustees, may participate in a meeting of the Trustees, or any such 
committee, as the case may be, by means of a conference telephone or similar 
communications equipment if all persons participating in the meeting can hear 
each other at the same time. Participation in a meeting by these means 
constitutes presence in person at the meeting. 

   SECTION 4.4. QUORUM, VOTING AND ADJOURNMENT OF MEETINGS. At all meetings 
of the Trustees, a majority of the Trustees shall be requisite to and shall 
constitute a quorum for the transaction of business. If a quorum is present, 
the affirmative vote of a majority of the Trustees present shall be the act 
of the Trustees, unless the concurrence of a greater proportion is expressly 
required for such action by law, the Declaration or these By-Laws. If at any 
meeting of the Trustees there be less than a quorum present, the Trustees 
present thereat may adjourn the meeting from time to time, without notice 
other than announcement at the meeting, until a quorum shall have been 
obtained. 

   SECTION 4.5. ACTION BY TRUSTEES WITHOUT MEETING. The provisions of these 
By-Laws covering notices and meetings to the contrary notwithstanding, and 
except as required by law, any action required or permitted to be taken at 
any meeting of the Trustees may be taken without a meeting if a consent in 
writing setting forth the action shall be signed by all of the Trustees 
entitled to vote upon the action and such written consent is filed with the 
minutes of proceedings of the Trustees. 

   SECTION 4.6. EXPENSES AND FEES. Each Trustee may be allowed expenses, if 
any, for attendance at each regular or special meeting of the Trustees, and 
each Trustee who is not an officer or employee of the Trust or of its 
investment manager or underwriter or of any corporate affiliate of any of 
said persons shall receive for services rendered as a Trustee of the Trust 
such compensation as may be fixed by the Trustees. Nothing herein contained 
shall be construed to preclude any Trustee from serving the Trust in any 
other capacity and receiving compensation therefor. 

   SECTION 4.7.  EXECUTION OF INSTRUMENTS AND DOCUMENTS AND SIGNING OF CHECKS 
AND OTHER OBLIGATIONS AND TRANSFERS. All instruments, documents and other 
papers shall be executed in the name and on behalf of the Trust and all 
checks, notes, drafts and other obligations for the payment of money by the 
Trust shall be signed, and all transfer of securities standing in the name of 
the Trust shall be executed, by the Chairman, the President, any Vice 
President or the Treasurer or by any one or more officers or agents of the 
Trust as shall be designated for that purpose by vote of the Trustees; 
notwithstanding the above, nothing in this Section 4.7 shall be deemed to 
preclude the electronic authorization, by designated persons, of the Trust's 
Custodian (as described herein in Section 9.1) to transfer assets of the 
Trust, as provided for herein in Section 9.1. 

   SECTION 4.8. INDEMNIFICATION OF TRUSTEES, OFFICERS, EMPLOYEES AND 
AGENTS. (a) The Trust shall indemnify any person who was or is a party or is 
threatened to be made a party to any threatened, pending, or completed 
action, suit or proceeding, whether civil, criminal, administrative or 
investigative 

                                3           
<PAGE>
(other than an action by or in the right of the Trust) by reason of the fact 
that he is or was a Trustee, officer, employee, or agent of the Trust. The 
indemnification shall be against expenses, including attorneys' fees, 
judgments, fines, and amounts paid in settlement, actually and reasonably 
incurred by him in connection with the action, suit, or proceeding, if he 
acted in good faith and in a manner he reasonably believed to be in or not 
opposed to the best interests of the Trust, and, with respect to any criminal 
action or proceeding, had no reasonable cause to believe his conduct was 
unlawful. The termination of any action, suit or proceeding by judgment, 
order, settlement, conviction, or upon a plea of nolo contendere or its 
equivalent, shall not, of itself, create a presumption that the person did 
not act in good faith and in a manner which he reasonably believed to be in 
or not opposed to the best interests of the Trust, and, with respect to any 
criminal action or proceeding, had reasonable cause to believe that his 
conduct was unlawful. 

   (b) The Trust shall indemnify any person who was or is a party or is 
threatened to be made a party to any threatened, pending or completed action 
or suit by or on behalf of the Trust to obtain a judgment or decree in its 
favor by reason of the fact that he is or was a Trustee, officer, employee, 
or agent of the Trust. The indemnification shall be against expenses, 
including attorneys' fees actually and reasonably incurred by him in 
connection with the defense or settlement of the action or suit, if he acted 
in good faith and in a manner he reasonably believed to be in or not opposed 
to the best interests of the Trust; except that no indemnification shall be 
made in respect of any claim, issue, or matter as to which the person has 
been adjudged to be liable for negligence or misconduct in the performance of 
his duty to the Trust, except to the extent that the court in which the 
action or suit was brought, or a court of equity in the county in which the 
Trust has its principal office, determines upon application that, despite the 
adjudication of liability but in view of all circumstances of the case, the 
person is fairly and reasonably entitled to indemnity for those expenses 
which the court shall deem proper, provided such Trustee, officer, employee 
or agent is not adjudged to be liable by reason of his willful misfeasance, 
bad faith, gross negligence or reckless disregard of the duties involved in 
the conduct of his office. 

   (c) To the extent that a Trustee, officer, employee, or agent of the Trust 
has been successful on the merits or otherwise in defense of any action, suit 
or proceeding referred to in subsection (a) or (b) or in defense of any 
claim, issue or matter therein, he shall be indemnified against expenses, 
including attorneys' fees, actually and reasonably incurred by him in 
connection therewith. 

   (d) (1) Unless a court orders otherwise, any indemnification under 
subsections (a) or (b) of this section may be made by the Trust only as 
authorized in the specific case after a determination that indemnification of 
the Trustee, officer, employee, or agent is proper in the circumstances 
because he has met the applicable standard of conduct set forth in 
subsections (a) or (b). 

       (2) The determination shall be made: 

         (i) By the Trustees, by a majority vote of a quorum which consists of
    Trustees who were not parties to the action, suit or proceeding; or 

        (ii) If the required quorum is not obtainable, or if a quorum of 
    disinterested Trustees so directs, by independent legal counsel in a 
    written opinion; or 

       (iii) By the Shareholders. 

     (3) Notwithstanding any provision of this Section 4.8, no person shall 
    be entitled to indemnification for any liability, whether or not there is 
    an adjudication of liability, arising by reason of willful misfeasance, 
    bad faith, gross negligence, or reckless disregard of duties as described 
    in Section 17(h) and (i) of the Investment Company Act of 1940 
    ("disabling conduct"). A person shall be deemed not liable by reason of 
    disabling conduct if, either: 

       (i) a final decision on the merits is made by a court or other body 
    before whom the proceeding was brought that the person to be indemnified 
    ("indemnitee") was not liable by reason of disabling conduct; or 

      (ii) in the absence of such a decision, a reasonable determination, 
    based upon a review of the facts, that the indemnitee was not liable by 
    reason of disabling conduct, is made by either-- 

                                4           
<PAGE>
          (A) a majority of a quorum of Trustees who are neither "interested 
         persons" of the Trust, as defined in Section 2(a)(19) of the 
         Investment Company Act of 1940, nor parties to the action, suit or 
         proceeding, or 

          (B) an independent legal counsel in a written opinion. 

   (e) Expenses, including attorneys' fees, incurred by a Trustee, officer, 
employee or agent of the Trust in defending a civil or criminal action, suit 
or proceeding may be paid by the Trust in advance of the final disposition 
thereof if: 

        (1) authorized in the specific case by the Trustees; and 

        (2) the Trust receives an undertaking by or on behalf of the Trustee, 
    officer, employee or agent of the Trust to repay the advance if it is not 
    ultimately determined that such person is entitled to be indemnified by 
    the Trust; and 

        (3) either, (i) such person provides a security for his undertaking, 
    or 

           (ii) the Trust is insured against losses by reason of any lawful 
         advances, or 

          (iii) a determination, based on a review of readily available 
         facts, that there is reason to believe that such person ultimately 
         will be found entitled to indemnification, is made by either-- 

              (A) a majority of a quorum which consists of Trustees who are 
             neither "interested persons" of the Trust, as defined in Section 
             2(a)(19) of the 1940 Act, nor parties to the action, suit or 
             proceeding, or 

              (B) an independent legal counsel in a written opinion. 

   (f) The indemnification provided by this Section shall not be deemed 
exclusive of any other rights to which a person may be entitled under any 
by-law, agreement, vote of Shareholders or disinterested Trustees or 
otherwise, both as to action in his official capacity and as to action in 
another capacity while holding the office, and shall continue as to a person 
who has ceased to be a Trustee, officer, employee, or agent and inure to the 
benefit of the heirs, executors and administrators of such person; provided 
that no person may satisfy any right of indemnity or reimbursement granted 
herein or to which he may be otherwise entitled except out of the property of 
the Trust, and no Shareholder shall be personally liable with respect to any 
claim for indemnity or reimbursement or otherwise. 

   (g) The Trust may purchase and maintain insurance on behalf of any person 
who is or was a Trustee, officer, employee, or agent of the Trust, against 
any liability asserted against him and incurred by him in any such capacity, 
or arising out of his status as such. However, in no event will the Trust 
purchase insurance to indemnify any officer or Trustee against liability for 
any act for which the Trust itself is not permitted to indemnify him. 

   (h) Nothing contained in this Section shall be construed to protect any 
Trustee or officer of the Trust against any liability to the Trust or to its 
security holders to which he would otherwise be subject by reason of willful 
misfeasance, bad faith, gross negligence or reckless disregard of the duties 
involved in the conduct of his office. 

                                  ARTICLE V 
                                  COMMITTEES 

   SECTION 5.1. EXECUTIVE AND OTHER COMMITTEES. The Trustees, by resolution 
adopted by a majority of the Trustees, may designate an Executive Committee 
and/or committees, each committee to consist of two (2) or more of the 
Trustees of the Trust and may delegate to such committees, in the intervals 
between meetings of the Trustees, any or all of the powers of the Trustees in 
the management of the business and affairs of the Trust. In the absence of 
any member of any such committee, the members thereof present at any meeting, 
whether or not they constitute a quorum, may appoint a Trustee to act in 
place of such absent member. Each such committee shall keep a record of its 
proceedings. 

                                5           
<PAGE>
   The Executive Committee and any other committee shall fix its own rules or 
procedure, but the presence of at least fifty percent (50%) of the members of 
the whole committee shall in each case be necessary to constitute a quorum of 
the committee and the affirmative vote of the majority of the members of the 
committee present at the meeting shall be necessary to take action. 

   All actions of the Executive Committee shall be reported to the Trustees 
at the meeting thereof next succeeding to the taking of such action. 

   SECTION 5.2. ADVISORY COMMITTEE. The Trustees may appoint an advisory 
committee which shall be composed of persons who do not serve the Trust in 
any other capacity and which shall have advisory functions with respect to 
the investments of the Trust but which shall have no power to determine that 
any security or other investment shall be purchased, sold or otherwise 
disposed of by the Trust. The number of persons constituting any such 
advisory committee shall be determined from time to time by the Trustees. The 
members of any such advisory committee may receive compensation for their 
services and may be allowed such fees and expenses for the attendance at 
meetings as the Trustees may from time to time determine to be appropriate. 

   SECTION 5.3. COMMITTEE ACTION WITHOUT MEETING. The provisions of these 
By-Laws covering notices and meetings to the contrary notwithstanding, and 
except as required by law, any action required or permitted to be taken at

5.1 of these By-Laws may be taken without a meeting if a consent in writing 
setting forth the action shall be signed by all members of the Committee 
entitled to vote upon the action and such written consent is filed with the 
records of the proceedings of the Committee.

   SECTION 6.1. EXECUTIVE OFFICERS. The executive officers of the Trust shall 
be a Chairman, a President, one or more Vice Presidents, a Secretary and a 
Treasurer. The Chairman shall be selected from among the Trustees but none of

those of President and any Vice President, may be held by the same person,

   SECTION 6.3. TERM AND REMOVAL AND VACANCIES. Each officer of the Trust 
shall hold office until his successor is elected and has qualified. Any 
officer or agent of the Trust may be removed by the Trustees whenever, in 
their judgment, the best interests of the Trust will be served thereby, but 
such removal shall be without prejudice to the contractual rights, if any, of 
the person so removed.

   Subject to any applicable provisions of law and the Declaration, dividends

<PAGE>
   Inasmuch as the computation of net income and net profits from the sales 
of securities or other properties for federal income tax purposes may vary 
from the computation thereof on the records of the Trust, the Trustees shall 
have power, in their discretion, to distribute as income dividends and as 
capital gain distributions, respectively, amounts sufficient to enable the 
Trust to avoid or reduce liability for federal income taxes. 

                                 ARTICLE VIII 
                            CERTIFICATES OF SHARES 

   SECTION 8.1. CERTIFICATES OF SHARES. Certificates for Shares of each 
series or class of Shares shall be in such form and of such design as the 
Trustees shall approve, subject to the right of the Trustees to change such

records of the Trust as they are issued. Each such certificate shall bear a 
distinguishing number; shall exhibit the holder's name and certify the number

Trust by the President, or a Vice President, and countersigned by the

Transfer Agent or by a Registrar, the signature of such officers and the seal 
may be facsimile, printed or engraved. The Trust may, at its option, 
determine not to issue a certificate or certificates to evidence Shares owned 
of record by any Shareholder. 

   In case any officer or officers who shall have signed, or whose facsimile 
signature or signatures shall appear on, any such certificate or certificates 
shall cease to be such officer or officers of the Trust, whether because of 
death, resignation or otherwise, before such certificate or certificates 
shall have been delivered by the Trust, such certificate or certificates 
shall, nevertheless, be adopted by the Trust and be issued and delivered as 
though the person or persons who signed such certificate or certificates or 
whose facsimile signature or signatures shall appear therein had not ceased 
to be such officer or officers of the Trust. 

   No certificate shall be issued for any share until such share is fully 
paid. 

   SECTION 8.2. LOST, STOLEN, DESTROYED AND MUTILATED CERTIFICATES. The 
Trustees may direct a new certificate or certificates to be issued in place 
of any certificate or certificates theretofore issued by the Trust alleged to 
have been lost, stolen or destroyed, upon satisfactory proof of such loss, 
theft, or destruction; and the Trustees may, in their discretion, require the 
owner of the lost, stolen or destroyed certificate, or his legal 
representative, to give to the Trust and to such Registrar, Transfer Agent 
and/or Transfer Clerk as may be authorized or required to countersign such 
new certificate or certificates, a bond in such sum and of such type as they 
may direct, and with such surety or sureties, as they may direct, as 
indemnity against any claim that may be against them or any of them on 
account of or in connection with the alleged loss, theft or destruction of 
any such certificate. 

                                  ARTICLE IX

   SECTION 9.1. APPOINTMENT AND DUTIES. The Trust shall at times employ a 
bank or trust company having capital, surplus and undivided profits of at 
least five million dollars ($5,000,000) as custodian with authority as its 
agent, but subject to such restrictions, limitations and other requirements, 
if any, as may be contained in these By-Laws and the 1940 Act: 

     (1) to receive and hold the securities owned by the Trust and deliver 
    the same upon written or electronically transmitted order. 

     (2) to receive and receipt for any moneys due to the Trust and deposit 
    the same in its own banking department or elsewhere as the Trustees may 
    direct; 

     (3) to disburse such funds upon orders or vouchers; 

                                8           
<PAGE>
all upon such basis of compensation as may be agreed upon between the 
Trustees and the custodian. If so directed by a Majority Shareholder Vote, 
the custodian shall deliver and pay over all property of the Trust held by it 
as specified in such vote. 

   The Trustees may also authorize the custodian to employ one or more 
sub-custodians from time to time to perform such of the acts and services of 
the custodian and upon such terms and conditions as may be agreed upon 
between the custodian and such sub-custodian and approved by the Trustees. 

   SECTION 9.2. CENTRAL CERTIFICATE SYSTEM. Subject to such rules, 
regulations and orders as the Commission may adopt, the Trustees may direct 
the custodian to deposit all or any part of the securities owned by the Trust 
in a system for the central handling of securities established by a national 
securities exchange or a national securities association registered with the 
Commission under the Securities Exchange Act of 1934, or such other person as 
may be permitted by the Commission, or otherwise in accordance with the 1940 
Act, pursuant to which system all securities of any particular class or 
series of any issuer deposited within the system are treated as fungible and 
may be transferred or pledged by bookkeeping entry without physical delivery 
of such securities, provided that all such deposits shall be subject to 
withdrawal only upon the order of the Trust. 

                                  ARTICLE X 
                               WAIVER OF NOTICE 

   Whenever any notice of the time, place or purpose of any meeting of 
Shareholders, Trustees, or of any committee is required to be given in 
accordance with law or under the provisions of the Declaration or these 
By-Laws, a waiver thereof in writing, signed by the person or persons 
entitled to such notice and filed with the records of the meeting, whether 
before or after the holding thereof, or actual attendance at the meeting of 
shareholders, Trustees or committee, as the case may be, in person, shall be 
deemed equivalent to the giving of such notice to such person. 

                                  ARTICLE XI 
                                MISCELLANEOUS

places as the Trustees may from time to time determine, except as otherwise 
required by law. 

   SECTION 11.2 RECORD DATE. The Trustees may fix in advance a date as the 
record date for the purpose of determining the Shareholders entitled to (i) 
receive notice of, or to vote at, any meeting of Shareholders, or (ii) 
receive payment of any dividend or the allotment of any rights, or in order 
to make a determination of Shareholders for any other proper purpose. The 
record date, in any case, shall not be more than one hundred eighty (180) 
days, and in the case of a meeting of Shareholders not less than ten (10) 
days, prior to the date on which such meeting is to be held or the date on 
which such other particular action requiring determination of Shareholders is 
to be taken, as the case may be. In the case of a meeting of Shareholders, 
the meeting date set forth in the notice to Shareholders accompanying the 
proxy statement shall be the date used for purposes of calculating the 180 
day or 10 day period, and any adjourned meeting may be reconvened without a 
change in record date. In lieu of fixing a record date, the Trustees may 
provide that the transfer books shall be closed for a stated period but not 
to exceed, in any case, twenty (20) days. If the transfer books are closed 
for the purpose of determining Shareholders entitled to notice of a vote at a 
meeting of Shareholders, such books shall be closed for at least ten (10) 
days immediately preceding the meeting. 

   SECTION 11.3. SEAL. The Trustees shall adopt a seal, which shall be in 
such form and shall have such inscription thereon as the Trustees may from 
time to time provide. The seal of the Trust may be affixed to any document, 
and the seal and its attestation may be lithographed, engraved or otherwise 
printed on any document with the same force and effect as if it had been 
imprinted and attested manually in the same manner and with the same effect 
as if done by a Massachusetts business corporation under Massachusetts law.

   SECTION 11.4. FISCAL YEAR. The fiscal year of the Trust shall end on such 
date as the Trustees may by resolution specify, and the Trustees may by 
resolution change such date for future fiscal years at any time and from time 
to time. 

   SECTION 11.5. ORDERS FOR PAYMENT OF MONEY. All orders or instructions for 
the payment of money of the Trust, and all notes or other evidences of 
indebtedness issued in the name of the Trust, shall be signed by such officer 
or officers or such other person or persons as the Trustees may from time to 
time designate, or as may be specified in or pursuant to the agreement 
between the Trust and the bank or trust company appointed as Custodian of the 
securities and funds of the Trust. 

                                 ARTICLE XII 
                     COMPLIANCE WITH FEDERAL REGULATIONS 

   The Trustees are hereby empowered to take such action as they may deem to 
be necessary, desirable or appropriate so that the Trust is or shall be in 
compliance with any federal or state statute, rule or regulation with which 
compliance by the Trust is required. 

                                 ARTICLE XIII 
                                  AMENDMENTS 

   These By-Laws may be amended, altered, or repealed, or new By-Laws may be 
adopted, (a) by a Majority Shareholder Vote, or (b) by the Trustees; 
provided, however, that no By-Law may be amended, adopted or repealed by the 
Trustees if such amendment, adoption or repeal requires, pursuant to law, the 
Declaration, or these By-Laws, a vote of the Shareholders. The Trustees shall 
in no event adopt By-Laws which are in conflict with the Declaration, and any 
apparent inconsistency shall be construed in favor of the related provisions 
in the Declaration. 

                                 ARTICLE XIV 
                             DECLARATION OF TRUST 

   The Declaration of Trust establishing Dean Witter New York Tax-Free Income 
Fund, dated January 17, 1985, a copy of which is on file in the office of the 
Secretary of the Commonwealth of Massachusetts, provides that the name Dean 
Witter New York Tax-Free Income Fund refers to the Trustees under the 
Declaration collectively as Trustees, but not as individuals or personally;

       sales in each such State to the Fund as provided above and as agreed from
       time to time by the Fund and DWTFSB.
 
        (d) DWTFSB shall provide such additional services and functions not
