                  excess of $1 billion (see page 7).
- ----------------------------------------------------------------------------------------------------------------------
Distributor       Dean Witter Distributors Inc. (the "Distributor"). The Fund has adopted a distribution plan pursuant
and               to Rule 12b-1 under the Investment Company Act (the "12b-1 Plan") with respect to the distribution
Distribution      fees paid by the Class A, Class B and Class C shares of the Fund to the Distributor. The entire
Fee               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 19 and 27).
- ----------------------------------------------------------------------------------------------------------------------
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 19, 22 and 27).

<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. A different CDSC schedule applies to investments by
                  certain qualified plans. Class B shares are also subject to a 12b-1 fee assessed at the annual rate
                  of 0.85% 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 19, 24 and 27).
 
                  - 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 0.85% of average daily net assets of
                  the Class (see pages 19 and 27).
 
                  - 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 19 and 27).
- ----------------------------------------------------------------------------------------------------------------------
Dividends         Dividends from net investment income are declared and paid monthly. Capital gains, if any, are paid
and               at least annually. The Fund may, however, determine to retain all or part of any net long-term
Capital Gains     capital gains in any year for reinvestment. Dividends and capital gains distributions paid on shares
Distributions     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 30 and 34).
- ----------------------------------------------------------------------------------------------------------------------
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 33).
- ----------------------------------------------------------------------------------------------------------------------
Special           The net asset value of the Fund's shares will fluctuate with changes in the market value of its
Risk              portfolio securities. The Fund is a non-diversified investment company and, as such, is not subject
Considerations    to the diversification requirements of the Investment Company Act of 1940, as amended (see page 8).
                  In addition, it should be recognized that the foreign securities and markets in which the Fund will
                  invest pose different and possibly greater risks than those customarily associated with domestic
                  securities and their markets. Moreover, investors should consider other risks associated with a
                  portfolio of international securities, including fluctuations in foreign currency exchange rates
                  (i.e., if a substantial portion of the Fund's assets are denominated in foreign currencies which
                  decrease in value with respect to the U.S. dollar, the value of the investor's shares and the
                  distributions made on those shares will, likewise, decrease in value), foreign securities exchange
                  controls and foreign tax rates, as well as investments in forward currency contracts, options and
                  futures contracts (see page 10).

(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 0.85% 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 THE
    DATE OF THIS PROSPECTUS. ACCORDINGLY, "TOTAL FUND OPERATING EXPENSES," AS
    SHOWN ABOVE WITH RESPECT TO THOSE CLASSES, ARE BASED UPON THE SUM OF 12B-1
    FEES, MANAGEMENT FEES AND ESTIMATED "OTHER EXPENSES."

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
    Dean Witter World Wide Income Trust (the "Fund") is an open-end,
non-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 October 14, 1988.
 
   
    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, Discover &
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 100 investment companies, 30 of which are listed on
the New York Stock Exchange, with combined total assets of approximately $93.1
billion as of June 30, 1997. The Investment Manager also manages portfolios of
pension plans, other institutions and individuals which aggregated approximately
$3.5 billion at such date.
    
 
    The Fund has retained the Investment Manager to provide administrative
services, manage its business affairs and manage the investment of the Fund's
assets, including the placing of orders for the purchase and sale of portfolio
securities. InterCapital has retained Dean Witter Services Company Inc. to
perform the aforementioned administrative services for the Fund.
 
    The Fund's Trustees review the various services provided by or under the
direction of the Investment Manager to ensure that the Fund's general investment
policies and programs are being properly carried out and that administrative
services are being provided to the Fund in a satisfactory manner.
 
    As full compensation for the services and facilities furnished to the Fund
and for expenses of the Fund assumed by the Investment Manager, the Fund pays
the Investment Manager monthly compensation calculated daily at an annual rate
of 0.75% of the daily net assets of the Fund up to $250 million, scaled down at
various asset levels to 0.30% of the daily net assets of the Fund exceeding $1
billion. For the fiscal year ended October 31, 1996, the Fund accrued total
compensation to the Investment Manager amounting to 0.75% of the Fund's average
daily net assets and the Fund's total expenses amounted to 1.96% of the Fund's
average daily net assets.
 
INVESTMENT OBJECTIVES AND POLICIES
- --------------------------------------------------------------------------------
 
    The primary investment objective of the Fund is to provide a high level of
current income. As a secondary objective, the Fund will seek appreciation in the
value of its assets. The Fund will attempt to achieve its investment objectives
by investing primarily in a portfolio of fixed-income securities issued by
foreign and U.S. corporations or issued or guaranteed by foreign governments,
government agencies or government subdivisions, supranational organizations (or
any subdivision thereof) and the U.S. Government, its agencies and
instrumentalities. There can be no assurance that the Fund will achieve its
objectives. The investment objectives are fundamental policies of the Fund and,
as such, may not be changed without the approval of the shareholders of the
Fund.
    The Fund may invest in securities issued by government entities or
corporations of any single nation and which are denominated in any single
currency. The Investment Manager will, however, actively allocate the Fund's
investments among various geographic regions, nations, currencies
 
                                       7
<PAGE>
and corporations or governmental entities in its attempt to maximize the
dividends paid on the Fund's shares and, if possible, the appreciation of their
value. In addition, it is the Fund's policy that, during normal market
conditions, its assets will be comprised of investments in the securities of
issuers located in at least three separate nations (which may include the United
States). The Investment Manager will consider such factors as the yield of
individual securities, the anticipated appreciation of such securities, the
state of the economies of the countries in which the investments are made, the
levels of inflation existing in such countries, the liquidity and financial
soundness of the markets in which such securities trade, the levels of inflation
existing within the relevant country and the current and anticipated
relationships of such countries' currencies to the U.S. dollar. The currency in
which the Fund's securities will be principally denominated will be a function
of these factors in that, at any given time, the Investment Manager may
determine, after review of these factors, that the fixed-income securities in a
given country are superior to the fixed-income securities in a different
country, and, accordingly, increase the proportion of the Fund's assets
denominated in the currency of the country with the superior investment climate.
 
    It is anticipated that the securities held by the Fund in its portfolio will
be denominated, principally, in the following currencies: the United States
dollar, Australian dollar, New Zealand dollar, German mark, Japanese yen, French
franc, British pound, Canadian dollar, Mexican peso, Swiss franc, Dutch guilder,
Belgian franc, Swedish kronor, Italian lira, Finnish markka and European
Currency Unit (a weighted composite of the currencies of member states of the
European Monetary System). Securities of issuers within a given country may be
denominated in the currency of a different country.
 
    The U.S. Government securities in which the Fund may invest include U.S.
Treasury bonds, notes and bills, which are direct obligations of the U.S.
Government as well as in securities issued or guaranteed by agencies and
instrumentalities of the U.S. Government. Some of the securities of such
agencies and instrumentalities are backed by the full faith and credit of the
U.S. (e.g., the Government National Mortgage Association), while others are not
backed by the full faith and credit of the U.S. but are backed by the credit of
the issuing agency or instrumentality (e.g., the Federal Home Loan Bank) or are
backed by an existing line of credit with the U.S. Treasury from which its
issuing agency or instrumentality may borrow (e.g., the Federal National
Mortgage Association).
 
    The Fund may invest in fixed-income securities issued or guaranteed by
supranational organizations. Such organizations are entities designated or
supported by a government or government entity to promote economic development,
and include, among others, the Asian Development Bank, the European Coal and
Steel Community, the European Economic Community and the World Bank. These
organizations do not have taxing authority and are dependent upon their members
for payments of interest and principal. Each supranational entity's lending
activities are limited to a percentage of its total capital (including "callable
capital" contributed by members at the entity's call), reserves and net income.
Securities issued by supranational organizations may be denominated in U.S.
dollars or in foreign currencies.
 
    In seeking to achieve its objectives, the Fund will normally invest at least
65% of its assets in fixed-income securities issued or guaranteed by the U.S.
Government, its agencies and instrumentalities or fixed-income securities issued
by U.S. corporations, foreign governments, foreign corporations or other
entities which have been rated within the four highest categories as determined
by Moody's Investors Service, Inc. ("Moody's") (Aaa, Aa, A or Baa) or Standard &
Poor's Corporation ("S&P") (AAA, AA, A or BBB), or which are unrated by such
rating agencies but which are deemed to be of comparable quality by the
Investment Manager. The ratings of fixed-income securities by Moody's and S&P
are a generally accepted barometer of credit risk. Fixed-income securities rated
Baa by Moody's have
 
                                       8
<PAGE>
certain speculative characteristics. A description of S&P and Moody's ratings is
contained in the Statement of Additional Information.
 
    The types of fixed-income securities invested in by the Fund include
straight debt obligations of varying maturities, such as bonds, notes, bills,
debentures, equipment lease and trust certificates, conditional sales contracts,
commercial paper, commercial bank obligations, obligations of savings
institutions, bankers' acceptances, Eurodollar certificates of deposit and fixed
and adjustable rate preferred stocks.
 
    The Fund may invest without limitation in notes and commercial paper, the
principal amount of which is indexed to certain specific foreign currency
exchange rates. Indexed notes and commercial paper typically provide that their
principal amount is adjusted upwards or downwards (but not below zero) at
maturity to reflect fluctuations in the exchange rate between two currencies
during the period the obligation is outstanding, depending on the terms of the
specific security. In selecting the two currencies, the Investment Manager will
consider the correlation and relative yields of various currencies. The Fund
will purchase an indexed obligation using the currency in which it is
denominated and, at maturity, will receive interest and principal payments
thereon in that currency. The amount of principal payable by the issuer at
maturity, however, will vary (i.e., increase or decrease) in response to the
change (if any) in the exchange rates between the two specified currencies
during the period from the date the instrument is issued to its maturity date.
The potential for realizing gains as a result of changes in foreign currency
exchange rates may enable the Fund to hedge the currency in which the obligation
is denominated (or to effect cross-hedges against other currencies) against a
decline in the U.S. dollar value of investments denominated in foreign
currencies, while providing an attractive money market rate of return. The Fund
will purchase such indexed obligations to generate current income or for hedging
purposes and will not speculate in such obligations.
 
    Under normal conditions, a percentage of the short-term investments in the
Fund's portfolio may be money market securities. Money market securities include
short-term obligations issued or guaranteed by the U.S. Government or foreign
governments or issued by such governments' respective agencies and
instrumentalities, bank money market instruments including certificates of
deposit, bankers' acceptances, time deposits and deposit notes and certain other
short-term obligations such as short-term commercial paper. With respect to bank
money instruments, the obligations may be issued by U.S. or foreign depository
institutions, foreign branches or subsidiaries of U.S. depository institutions
("Eurodollar" obligations), U.S. branches or subsidiaries of foreign depository
institutions ("Yankeedollar" obligations) or foreign branches or subsidiaries of
foreign depository institutions. Eurodollar and Yankeedollar obligations and
obligations of branches or subsidiaries of foreign depository institutions may
be general obligations of the parent bank or may be limited to the issuing
branch or subsidiary by the terms of the specific obligations or by government
regulation.
 
    In addition, the Fund may invest in fixed-income securities which are
convertible into common stock, such as convertible debentures and convertible
preferred stock, and fixed-income securities to which are attached equity
features such as shares of common stock, warrants for the purchase of common
stock, participations based on revenues, sales or profits and other conversion
and/or exchange rights.
 
    The Fund may also invest in securities of foreign issuers in the form of
American Depository Receipts (ADRs), European Depository Receipts (EDRs) or
other similar securities convertible into securities of foreign issuers. These
securities may not necessarily be denominated in the same currency as the
securities into which they may be converted. ADRs are receipts typically issued
by a United States bank or trust company evidencing ownership of the underlying
securities. EDRs are European receipts evidencing a similar
arrange-
 
                                       9
<PAGE>
ment. Generally, ADRs, in registered form, are designed for use in the United
States securities markets and EDRs, in bearer form, are designed for use in
European securities markets.
 
    There may be periods during which, in the opinion of the Investment Manager,
market conditions warrant reduction of some or all of the Fund's securities
holdings. During such periods, the Fund may adopt a temporary "defensive"
posture in which greater than 35% of its assets are invested in cash or money
market instruments. Under such circumstances, the money market instruments in
which the Fund may invest are securities issued or guaranteed by the U.S.
Government; U.S. bank obligations; Eurodollar certificates of deposit;
obligations of American savings institutions; fully insured certificates of
deposit; and commercial paper of U.S. issuers rated within the two highest
grades by Moody's or S&P or, if not rated, are issued by a company having an
outstanding debt issue rated at least AA by S&P or Aa by Moody's.
 
RISK CONSIDERATIONS
 
    The net asset value of the Fund's shares will fluctuate with changes in the
market value of its portfolio securities. The market value of the Fund's
portfolio securities will increase or decrease due to a variety of economic,
market or political factors which cannot be predicted. The Fund's yield will
also vary based on the yield of the Fund's portfolio securities.
 
    All fixed-income securities are subject to two types of risks: the credit
risk and the interest rate risk. The credit risk relates to the ability of the
issuer to meet interest or principal payments or both as they come due. The
interest rate risk refers to the fluctuations in the net asset value of any
portfolio of fixed-income securities resulting from the inverse relationship
between price and yield of fixed-income securities; that is, when the general
level of interest rates rises, the prices of outstanding fixed-income securities
decline, and when interest rates fall, prices rise.
 
    The Fund may also purchase fixed-income securities which are issued by U.S.
issuers and which are denominated in U.S. dollars but which return principal to
investors in amounts which are tied to the exchange rate between the U.S. dollar
and a foreign currency. The payment of interest on such securities is generally
made at a fixed U.S. dollar rate.
 
    NON-DIVERSIFIED STATUS.  The Fund is a non-diversified investment company
and, as such, is not subject to the diversification requirements of the
Investment Company Act of 1940, as amended (the "Act"). As a non-diversified
investment company, the Fund may invest a greater portion of its assets in the
securities of a single issuer and thus is subject to greater exposure to risks
such as a decline in the credit rating of that issuer. However, the Fund
anticipates that it will qualify as a regulated investment company under the
federal income tax laws and, if so qualified, will be subject to the applicable
diversification requirements of the Internal Revenue Code, as amended (the
"Code"). As a regulated investment company under the Code, the Fund may not, as
of the end of any of its fiscal quarters, have invested more than 25% of its
total assets in the securities of any one issuer (including a foreign
government), or as to 50% of its total assets, have invested more than 5% of its
total assets in the securities of a single issuer.
 
    FOREIGN SECURITIES.  Investors should carefully consider the risks of
investing in securities of foreign issuers and securities denominated in
non-U.S. currencies. Fluctuations in the relative rates of exchange between the
currencies of different nations may affect the value of the Fund's investments.
Changes in foreign currency exchange rates relative to the U.S. dollar will
affect the U.S. dollar value of the Fund's assets denominated in that currency
and thereby impact upon the Fund's yield on such assets and the net asset value
of a share of the Fund as well as the amount of the Fund's distributions. For
example, if a substantial portion of the Fund's assets are denominated in
Japanese yen and the relative exchange rate of the yen falls with respect to the
U.S. dollar (i.e., a yen is worth a smaller fraction of a dollar than it had
been) then the Fund will be receiving a lesser amount of interest on
 
                                       10
<PAGE>
its fixed-income securities denominated in yen (when converted into U.S.
dollars) and when the Fund's assets are valued for purposes of determining the
net asset value per share of the Fund, the net assets of the Fund reflected by
the yen-denominated securities will have declined in U.S. dollar value and the
net asset value of the Fund (always stated in U.S. dollars) may have also
declined.
 
    Foreign currency exchange rates are determined by forces of supply and
demand on the foreign exchange markets. These forces are themselves affected by
the international balance of payments and other economic and financial
conditions, government intervention, speculation and other factors. Moreover,
foreign currency exchange rates may be affected by the regulatory control of the
exchanges on which the currencies trade. The foreign currency transactions of
the Fund will be conducted on a spot basis or through forward contracts or
futures contracts (see below). The Fund may incur certain costs in connection
with these currency transactions.
 
    Investments in foreign securities will also occasion risks relating to
political and economic developments abroad, including the possibility of
expropriations or confiscatory taxation, limitations on the use or transfer of
Fund assets and any effects of foreign social, economic or political
instability. Foreign companies are not subject to the regulatory requirements of
U.S. companies and, as such, there may be less publicly available information
about such companies. Moreover, foreign companies are not generally subject to
uniform accounting, auditing and financial standards and requirements comparable
to those applicable to U.S. companies.
 
    Securities of foreign issuers may be less liquid than comparable securities
of U.S. issuers and, as such, their price changes may be more volatile.
Furthermore, foreign exchanges and broker-dealers are generally subject to less
government and exchange scrutiny and regulation than their American
counterparts. Brokerage commissions, dealer concessions and other transaction
costs may be higher on foreign markets than in the U.S. In addition, differences
in clearance and settlement procedures on foreign markets may occasion delays in
settlements of Fund trades effected in such markets. Inability to dispose of
portfolio securities due to settlement delays could result in losses to the Fund
due to subsequent declines in value of such securities and the inability of the
Fund to make intended security purchases due to settlement problems could result
in a failure of the Fund to make potentially advantageous investments.
                                  ------------
 
    To hedge against adverse price movements in the securities held in its
portfolio and the currencies in which they are denominated (as well as in the
securities it might wish to purchase and their denominated currencies) the Fund
may engage in transactions in forward foreign currency contracts, options on
securities and currencies, and futures contracts and options on futures
contracts on securities, currencies and indexes. The Fund may also write options
on securities and currencies to assist it in meeting its objective of providing
a high level of current income. A discussion of these transactions follows and
is supplemented by further disclosure in the Statement of Additional
Information.
 
    FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS. A forward foreign currency
exchange contract ("forward contract") involves an obligation to purchase or
sell a currency at a future date, which may be any fixed number of days from the
date of the contract agreed upon by the parties, at a price set at the time of
the contract. The Fund may enter into forward contracts as a hedge against
fluctuations in future foreign exchange rates.
 
    The Fund will enter into forward contracts under various circumstances. When
the Fund enters into a contract for the purchase or sale of a security
denominated in a foreign currency, it may, for example, desire to "lock in" the
price of the security in U.S. dollars or some other foreign currency which the
Fund is temporarily holding in its portfolio. By entering into a forward
contract for the purchase or sale, for a fixed amount of dollars or
 
                                       11
<PAGE>
other currency, of the amount of foreign currency involved in the underlying
security transactions, the Fund will be able to protect itself against a
possible loss resulting from an adverse change in the relationship between the
U.S. dollar or other currency which is being used for the security purchase and
the foreign currency in which the security is denominated during the period
between the date on which the security is purchased or sold and the date on
which payment is made or received.
 
    At other times, when, for example, the Fund's Investment Manager believes
that the currency of a particular foreign country may suffer a substantial
decline against the U.S. dollar or some other foreign currency, it may enter
into a forward contract to sell, for a fixed amount of dollars or other
currency, the amount of foreign currency approximating the value of some or all
of the Fund's portfolio securities (or securities which the Fund has purchased
for its portfolio) denominated in such foreign currency. Under identical
circumstances, the Fund may enter into a forward contract to sell, for a fixed
amount of U.S. dollars or other currency, an amount of foreign currency other
than the currency in which the securities to be hedged are denominated
approximating the value of some or all of the portfolio securities to be hedged.
The Investment Manager will select this method of hedging, called
"cross-hedging," when it determines that the foreign currency in which the
portfolio securities are denominated have insufficient liquidity or are trading
at a discount as compared with some other foreign currency with which it tends
to move in tandem.
 
    In addition, when the Fund's Investment Manager anticipates purchasing
securities at some time in the future, and wishes to lock in the current
exchange rate of the currency in which those securities are denominated against
the U.S. dollar or some other foreign currency, it may enter into a forward
contract to purchase an amount of currency equal to some or all of the value of
the anticipated purchase, for a fixed amount of U.S. dollars or other currency.
The Fund may, however, close out the forward contract without purchasing the
security which was the subject of the "anticipatory" hedge.
 
    Lastly, the Fund is permitted to enter into forward contracts with respect
to currencies in which certain of its portfolio securities are denominated and
on which options have been written (see "Options and Futures Transactions").
 
    In all of the above circumstances, if the currency in which the Fund's
portfolio securities (or anticipated portfolio securities) are denominated rises
in value with respect to the currency which is being purchased (or sold), then
the Fund will have realized fewer gains than had the Fund not entered into the
forward contracts. Moreover, the precise matching of the forward contract
amounts and the value of the securities involved will not generally be possible,
since the future value of such securities in foreign currencies will change as a
consequence of market movements in the value of those securities between the
date the forward contract is entered into and the date it matures. The Fund is
not required to enter into such transactions with regard to its foreign
currency-denominated securities and will not do so unless deemed appropriate by
the Investment Manager.
 
    The Fund generally will not enter into a forward contract with a term of
greater than one year, although it may enter into forward contracts for periods
of up to five years. To the extent that the Fund enters into forward foreign
currency contracts to hedge against a decline in the value of portfolio holdings
denominated in a particular foreign currency resulting from currency
fluctuations, there is a risk that the Fund may nevertheless realize a gain or
loss as a result of currency fluctuations after such portfolio holdings are sold
if the Fund is unable to enter into an "offsetting" forward foreign currency
contract with the same party or another party. The Fund may be limited in its
ability to enter into hedging transactions involving forward contracts by the
Code requirements relating to qualification as a regulated investment company
(see "Dividends, Distributions and Taxes").
 
                                       12
<PAGE>
OPTIONS AND FUTURES TRANSACTIONS
 
    The Fund may purchase and sell (write) call and put options on U.S. Treasury
notes, bonds and bills, on various foreign currencies and on equity securities
which are listed on several U.S. and foreign securities exchanges and are
written in over-the-counter transactions ("OTC options"). Listed options are
issued or guaranteed by the exchange on which they trade or by a clearing
corporation such as the Options Clearing Corporation ("OCC"). Ownership of a
listed call option gives the Fund the right to buy from the OCC (in the U.S.) or
other clearing corporation or exchange, the underlying security or currency
covered by the option at the stated exercise price (the price per unit of the
underlying security or currency) by filing an exercise notice prior to the
expiration date of the option. Ownership of a listed put option would give the
Fund the right to sell the underlying security or currency to the OCC (in the
U.S.) or other clearing corporation or exchange at the stated exercise price.
OTC options are purchased from or sold (written) to dealers or financial
institutions which have entered into direct agreements with the Fund. With
respect to OTC options, such variables as expiration date, exercise price and
premium will be agreed upon between the Fund and the transacting dealer, without
the intermediation of a third party such as the OCC.
 
    COVERED CALL WRITING.  The Fund is permitted to write covered call options
on portfolio securities which are denominated in either U.S. dollars or foreign
currencies, without limit, in order to aid it in achieving its investment
objectives and to close out long call option positions. As a writer of a call
option, the Fund has the obligation, upon notice of exercise of the option, to
deliver the security or amount of currency underlying the option (certain listed
and OTC call options written by the Fund will be exercisable by the purchaser
only on a specific date).
 
    COVERED PUT WRITING.  As a writer of covered put options, the Fund incurs an
obligation to buy the security (or currency) underlying the option from the
purchaser of the put at the option's exercise price at any time during the
option period, at the purchaser's election (certain listed and OTC put options
written by the Fund will be exercisable by the purchaser only on a specific
date). The Fund will write put options for three purposes: (1) to receive the
premiums paid by purchasers; (2) when the Investment Manager wishes to purchase
the security underlying the option (or a security denominated in the currency
underlying the option) at a price lower than its current market price, in which
case it will write the covered put at an exercise price reflecting the lower
purchase price sought; and (3) to close out a long put option position. The
aggregate value of the obligations underlying the puts determined as of the date
the options are sold will not exceed 50% of the Fund's net assets.
 
    PURCHASING CALL AND PUT OPTIONS.  The Fund may purchase listed and OTC call
and put options in amounts equalling up to 5% of its total assets. The Fund may
purchase call options to close out a written call position or to protect against
an increase in the price of a security it anticipates purchasing or, in the case
of call options on a foreign currency, to hedge against an adverse exchange rate
change of the currency in which the security it anticipates purchasing is
denominated vis-a-vis the currency in which the exercise price is denominated.
The Fund may purchase put options on securities which it holds in its portfolio
only to protect itself against a decline in the value of the security.
Similarly, the Fund may purchase put options on currencies in which securities
which it holds are denominated only to protect itself against a decline in value
of such currency vis-a-vis the currency in which the exercise price is
denominated. There are no other limits on the Fund's ability to purchase call
and put options.
 
    FUTURES CONTRACTS.  The Fund may purchase and sell futures contracts that
are currently traded, or may in the future be traded, on U.S. and foreign
commodity exchanges on such underlying fixed-income securities as U.S. Treasury
bonds, notes, and bills and/or any foreign government fixed-income security
("interest rate" futures), on various
 
                                       13
<PAGE>
currencies ("currency" futures) and on such indexes of U.S. or foreign
fixed-income securities as may exist or come into being, such as the Moody's
Investment-Grade Corporate Bond Index ("index" futures). As a futures contract
purchaser, the Fund incurs an obligation to take delivery of a specified amount
of the obligation underlying the contract at a specified time in the future for
a specified price. As a seller of a futures contract, the Fund incurs an
obligation to deliver the specified amount of the underlying obligation at a
specified time in return for an agreed upon price.
 
    The Fund will purchase or sell interest rate futures contracts for the
purpose of hedging the value of its fixed-income portfolio securities (or
anticipated portfolio securities) against changes in prevailing interest rates.
The Fund will purchase or sell index futures contracts for the purpose of
hedging its fixed-income portfolio (or anticipated portfolio) against changes in
their prices. The Fund will purchase or sell currency futures on currencies in
which its portfolio securities (or anticipated portfolio securities) are
denominated for the purposes of hedging against anticipated changes in currency
exchange rates. In addition to the above, interest rate, index and currency
futures will be bought or sold in order to close out a short or long position
maintained by the Fund in a corresponding futures contract.
 
    OPTIONS ON FUTURES CONTRACTS.  The Fund may purchase and write call and put
options on futures contracts which are traded on an exchange and enter into
closing transactions with respect to such options to terminate an existing
position. An option on a futures contract gives the purchaser the right (in
return for the premium paid) to assume a position in a futures contract (a long
position if the option is a call and a short position if the option is a put) at
a specified exercise price at any time during the term of the option.
 
    The Fund will purchase and write options on futures contracts for identical
purposes to those set forth above for the purchase of a futures contract
(purchase of a call option or sale of a put option) and the sale of a futures
contract (purchase of a put option or sale of a call option), or to close out a
long or short position in futures contracts.
 
    RISKS OF OPTIONS AND FUTURES TRANSACTIONS. The Fund may close out its
position as writer of an option, or as a buyer or seller of a futures contract,
only if a liquid secondary market exists for options or futures contracts of
that series. There is no assurance that such a market will exist, particularly
in the case of OTC options, as such options will generally only be closed out by
entering into a closing purchase transaction with the purchasing dealer.
 
    Exchanges may limit the amount by which the price of many futures contracts
may move on any day. If the price moves equal the daily limit on successive
days, then it may prove impossible to liquidate a futures position until the
daily limit moves have ceased.
 
    While the futures contracts and options transactions to be engaged in by the
Fund for the purpose of hedging the Fund's portfolio securities are not
speculative in nature, there are risks inherent in the use of such instruments.
One such risk is that the Investment Manager could be incorrect in its
expectations as to the direction or extent of various interest rate or price
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.
 
    Another risk which may arise in employing futures contracts to protect
against the price volatility of portfolio securities is that the prices of
securities, currencies and indexes subject to futures contracts (and thereby the
futures contract prices) may correlate imperfectly with the behavior of the U.S.
dollar cash prices of the Fund's portfolio securities and their denominated
currencies. Another such risk is that prices of interest rate futures contracts
may not move in tandem with the changes in prevailing interest rates against
which the Fund seeks a
 
                                       14
<PAGE>
hedge. A correlation may also 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.
 
    The Fund, by entering into transactions in foreign futures and options
markets, will also incur risks similar to those discussed above under the
section entitled "Foreign Securities."
 
OTHER INVESTMENT POLICIES
 
    REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements, which
may be viewed as a type of secured lending by the Fund, and which typically
involve the acquisition by the Fund of debt securities from a selling financial
institution such as a bank, savings and loan association or broker-dealer. The
agreement provides that the Fund will sell back to the institution, and that the
institution will repurchase, the underlying security at a specified price and at
a fixed time in the future, usually not more than seven days from the date of
purchase. While repurchase agreements involve certain risks not associated with
direct investments in debt securities, including the risks of default or
bankruptcy of the selling financial institution, the Fund follows procedures
designed to minimize those risks. These procedures include effecting repurchase
transactions only with large, well-capitalized and well-established financial
institutions whose financial condition will be continually monitored by the
Investment Manager subject to procedures established by the Board of Trustees of
the Fund.
 
    CONVERTIBLE SECURITIES.  A convertible security is a bond, debenture, note,
preferred stock or other security that may be converted into or exchanged for a
prescribed amount of common stock of the same or a different issuer within a
particular period of time at a specified price or formula. Convertible
securities rank senior to common stocks in a corporation's capital structure
and, therefore, entail less risk than the corporation's common stock. The value
of a convertible security is a function of its "investment value" (its value as
if it did not have a conversion privilege), and its "conversion value" (the
security's worth if it were to be exchanged for the underlying security, at
market value, pursuant to its conversion privilege). To the extent that a
convertible security's investment value is greater than its conversion value,
its price will be primarily a reflection of such investment value and its price
will be likely to increase when interest rates fall and decrease when interest
rates rise, as with a fixed-income security (the credit standing of the issuer
and other factors may also have an effect on the convertible security's value).
If the conversion value exceeds the investment value, the price of the
convertible security will rise above its investment value and, in addition, the
convertible security will sell at some premium over its conversion value. (This
premium represents the price investors are willing to pay for the privilege of
purchasing a fixed-income security with a possibility of capital appreciation
due to the conversion privilege.) At such times the price of the convertible
security will tend to fluctuate directly with the price of the underlying equity
security.
 
    REVERSE REPURCHASE AGREEMENTS.  The Fund may also use reverse repurchase
agreements as part of its investment strategy. Reverse repurchase agreements
involve sales by the Fund of portfolio assets concurrently with an agreement by
the Fund to repurchase the same assets at a later date at a fixed price. Reverse
repurchase agreements involve the risk that the market value of the securities
the Fund is obligated to repurchase under the agreement may decline below the
repurchase price. In the event the buyer of securities under a reverse
repurchase agreement files for bankruptcy or becomes insolvent, the Fund's use
of the proceeds of the agreement may be restricted pending a determination by
the other party, or its trustee or receiver, whether to enforce the Fund's
obligation to repurchase the securities. Reverse repurchase agreements are
speculative techniques involving leverage, and are considered borrowings by the
Fund.
 
                                       15
<PAGE>
    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.
 
    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.
 
    WHEN, AS AND IF ISSUED SECURITIES.  The Fund may purchase securities on a
"when, as and if issued" basis under which the issuance of the security depends
upon the occurrence of a subsequent event, such as approval of a merger,
corporate reorganization, leveraged buyout or debt restructuring. If the
anticipated event does not occur and the securities are not issued, the Fund
will have lost an investment opportunity. 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, as and if issued" basis. An increase in the percentage of
the Fund's assets committed to the purchase of securities on a "when, as and if
issued" basis may increase the volatility of its net asset value.
 
    PRIVATE PLACEMENTS.  The Fund may invest up to 10% of its total assets in
securities which are subject to restrictions on resale because they have not
been registered under the Securities Act of 1933, as amended (the "Securities
Act"), or which are otherwise not readily marketable. (Securities eligible for
resale pursuant to Rule 144A of the Securities Act, and determined to be liquid
pursuant to the procedures discussed in the following paragraph, are not subject
to the foregoing restriction.) These securities are generally referred to as
private placements or restricted securities. Limitations on the resale of such
securities may have an adverse effect on their marketability, and may prevent
the Fund from disposing of them promptly at reasonable prices. The Fund may have
to bear the expense of registering such securities for resale and the risk of
substantial delays in effecting such registration.
 
    The Securities and Exchange Commission has adopted Rule 144A under the
Securities Act, which permits the Fund to sell restricted securities to
qualified institutional buyers without limitation. The Investment Manager,
pursuant to procedures adopted by the Trustees of the Fund, will make a
determination as to the liquidity of each restricted security purchased by the
Fund. If a restricted
 
                                       16
<PAGE>
security is determined to be "liquid," such security will not be included within
the category "illiquid securities," which is limited by the Fund's investment
restrictions to 10% of the Fund's total assets. Investing in Rule 144A
securities could have the effect of increasing the level of Fund illiquidity to
the extent the Fund, at a particular time, may be unable to find qualified
institutional buyers interested in purchasing such securities.
 
    LENDING OF PORTFOLIO SECURITIES.  Consistent with applicable regulatory
requirements, the Fund may lend its portfolio securities to brokers, dealers and
other financial institutions, provided that such loans are callable at any time
by the Fund (subject to certain notice provisions described in the Statement of
Additional Information), and are at all times secured by cash or cash
equivalents, which are maintained in a segregated account pursuant to applicable
regulations and that are at least equal to the market value, determined daily,
of the loaned securities. As with any extensions of credit, there are risks of
delay in recovery and in some cases even loss of rights in the collateral should
the borrower of the securities fail financially. However, loans of portfolio
securities will only be made to firms deemed by the Investment Manager to be
creditworthy and when the income which can be earned from such loans justifies
the attendant risks.
 
    Except as specifically noted, all investment objectives, policies and
practices discussed above are not fundamental policies of the Fund and, as such,
may be changed without shareholder approval.

PORTFOLIO MANAGEMENT
 
    The Fund's portfolio is actively managed by its Investment Manager with a
view to achieving the Fund's investment objectives.
 
   
    The Fund is managed within InterCapital's Taxable Fixed-Income Group, which
manages 24 funds and fund portfolios, with approximately $12.8 billion in assets
at June 30, 1997. Vinh Q. Tran, Vice President of InterCapital, and Peter J.
Seeley, Vice President of InterCapital since April, 1996, each a member of
InterCapital's Taxable Fixed-Income Group, are the primary portfolio managers of
the Fund. Messrs. Tran and Seeley have been the Fund's primary portfolio
managers since its inception and December, 1994, respectively. Mr. Tran has been
a portfolio manager with InterCapital for over five years. Mr. Seeley has been a
portfolio manager with InterCapital since July, 1994, prior to which time he was
a portfolio manager with Nikko Capital Management (October, 1992-June, 1994) and
prior thereto with Schroders Incorporated. 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")
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.
    
 
    Personnel of the Investment Manager have substantial experience in the use
of the investment techniques described above under the heading "Options and
Futures Transactions," which techniques require skills different from those
needed to select the portfolio securities underlying various options and futures
contracts.
 
   
    Securities purchased by the Fund are generally sold by dealers acting as
principal for their own accounts. Orders for transactions in other portfolio
securities and commodities are placed for the Fund with a number of brokers and
dealers, including DWR and other affiliated brokers and dealers. The Fund may
incur brokerage commissions on transactions conducted through such affiliates.
Pursuant to an order of the Securities and Exchange Commission, the Fund may
effect principal transactions in certain money market instruments with DWR.
    
 
                                       17
<PAGE>
    The Fund may sell portfolio securities without regard to the length of time
that they have been held, in order to take advantage of new investment
opportunities or yield differentials, or because the Fund desires to preserve
gains or limit losses due to changing economic conditions, interest rate trends,
or the financial condition of the issuer. It is not anticipated that the Fund's
portfolio turnover rate will exceed 300% in any one year. The Fund will incur
underwriting discount costs (on underwritten securities) and brokerage costs
commensurate with its portfolio turnover rate. Short term gains and losses may
result from such portfolio transactions. See "Dividends, Distributions and
Taxes" for a discussion of the tax implications of the Fund's transactions.
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    The investment restrictions listed below are among the restrictions which
have been adopted by the Fund as fundamental policies. Under the Act, a
fundamental policy may not be changed without the vote of a majority of the
outstanding voting securities of the Fund, as defined in the Act. For purposes
of the following limitations: (i) all percentage limitations apply immediately
after a purchase or initial investment, and (ii) any subsequent change in any
applicable percentage resulting from market fluctuations or other changes in
total or net assets does not require elimination of any security from the
portfolio.
 
    The Fund may not:
 
   1. Invest 25% or more of the value of its total assets in securities of
issuers in any one industry.
 
   2. Invest more than 5% of the value of its total assets in securities of
issuers having a record, together with predecessors, of less than three years of
continuous operation. This restriction shall not apply to any obligation issued
or guaranteed by the United States Government, its agencies or
instrumentalities.
 
   3. Purchase or sell commodities or commodities contracts except that the Fund
may purchase or write interest rate, currency and stock and bond index futures
contracts and related options thereon.
 
   4. 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 or variation margin for futures are not deemed to be
pledges of assets.)
 
   5. Purchase securities on margin (but the Fund may obtain short-term loans as
are necessary for the clearance of transactions). 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.
 
   6. Invest more than 10% of its total assets in "illiquid securities"
(securities for which market quotations are not readily available) and
repurchase agreements which have a maturity of longer than seven days.
Generally, OTC options and the assets used as "cover" for written OTC options
are illiquid securities. However, the Fund is permitted to treat the securities
it uses as cover for written OTC options as liquid provided it follows a
procedure whereby it will sell OTC options only to qualified dealers who agree
that the Fund may repurchase such options at a maximum price to be calculated
pursuant to a predetermined formula set forth in the option agreement. The
formula may vary from agreement to agreement, but is generally based on a
multiple of the premium received by the Fund for writing the option plus the
amount, if any, of the options intrinsic value. An OTC option is considered an
illiquid asset only to the extent that the maximum repurchase price under the
formula exceeds the intrinsic value of the option.
 
   
    Notwithstanding any other investment policy or restriction, the Fund may
seek to achieve its investment objectives by investing all or substantially all
of its assets in another investment company having substantially the same
investment objectives and policies as the Fund.

PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
   
GENERAL
    
 
   
    The Fund offers each class of its shares for sale to the public on a
continuous basis. Pursuant to a Distribution Agreement between the Fund and Dean
Witter Distributors Inc. (the "Distributor"), an affiliate of the Investment
Manager, shares of the Fund are distributed by the Distributor and offered by
DWR and other dealers which have entered into selected dealer 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 B shares purchased by certain qualified
employer-sponsored benefit plans are subject to a CDSC scaled down from 2.0% to
1.0% if redeemed within three 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 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 World Wide Income Trust, directly to
Dean Witter Trust Company (the "Transfer Agent") at P.O. Box 1040, Jersey City,
NJ 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 $1,000 within the first twelve months. In the
case of investments pursuant to Systematic Payroll Deduction Plans (including
Individual Retirement Plans), the Fund, in its discretion, may accept
investments without regard to any minimum amounts which would otherwise be
required, if the Fund has reason to believe that additional investments will
increase the investment in all accounts under such Plans to at least $1,000.
Certificates for shares purchased will not be issued
    
 
                                       19
<PAGE>
   
unless requested by the shareholder in writing to the Transfer Agent.
    
 
   
    Shares of the Fund are sold through the Distributor on a normal three
business day settlement basis; that is, payment is due on the third business day
(settlement date) after the order is placed with the Distributor. Since DWR and
other Selected Broker-Dealers forward investors' funds on settlement date, they
will benefit from the temporary use of the funds if payment is made prior
thereto. As noted above, orders placed directly with the Transfer Agent must be
accompanied by payment. Investors will be entitled to receive income dividends
and capital gains distributions if their order is received by the close of
business on the day prior to the record date for such dividends and
distributions. Sales personnel of a Selected Broker-Dealer are compensated for
selling shares of the Fund by the Distributor or any of its affiliates and/or
the Selected Broker-Dealer. In addition, some sales personnel of the Selected
Broker-Dealer will receive various types of non-cash compensation as special
sales incentives, including trips, educational and/or business seminars and
merchandise. The Fund and the Distributor reserve the right to reject any
purchase orders.
    
 
   
ALTERNATIVE PURCHASE ARRANGEMENTS
    
 
   
    The Fund offers several Classes of shares to investors designed to provide
them with the flexibility of selecting an investment best suited to their needs.
The general public is offered three Classes of shares: Class A shares, Class B
shares and Class C shares, which differ principally in terms of sales charges
and rate of expenses to which they are subject. A fourth Class of shares, Class
D shares, is offered only to limited categories of investors (see "No Load
Alternative--Class D Shares" below).
    
 
   
    Each Class A, Class B, Class C or Class D share of the Fund represents an
identical interest in the investment portfolio of the Fund except that Class A,
Class B and Class C shares bear the expenses of the ongoing shareholder service
fees, Class B and Class C shares bear the expenses of the ongoing distribution
fees and Class A, Class B and Class C shares which are redeemed subject to a
CDSC bear the expense of the additional incremental distribution costs resulting
from the CDSC applicable to shares of those Classes. The ongoing distribution
fees that are imposed on Class A, Class B and Class C shares will be imposed
directly against those Classes and not against all assets of the Fund and,
accordingly, such charges against one Class will not affect the net asset value
of any other Class or have any impact on investors choosing another sales charge
option. See "Plan of Distribution" and "Redemptions and Repurchases."
    
 
   
    Set forth below is a summary of the differences between the Classes and the
factors an investor should consider when selecting a particular Class. This
summary is qualified in its entirety by detailed discussion of each Class that
follows this summary.
    
 
   
    CLASS A SHARES.  Class A shares are sold at net asset value plus an initial
sales charge of up to 4.25%. The initial sales charge is reduced for certain
purchases. Investments of $1 million or more (and investments by certain other
limited categories of investors) are not subject to any sales charges at the
time of purchase but are subject to a CDSC of 1.0% on redemptions made within
one year after purchase, except for certain specific circumstances. Class A
shares are also subject to a 12b-1 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. (Class B shares purchased by certain
qualified employer-sponsored benefit plans are subject to a CDSC scaled down
from 2.0% to 1.0% if redeemed within three years after purchase.) This CDSC may
be waived for certain redemptions. Class B shares are also subject to an annual
12b-1 fee of 0.85% of the lesser of: (a) the average daily aggregate gross sales
of the Fund's Class B shares since the incep-
    
 
                                       20
<PAGE>
   
tion 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 0.85% of the average daily net assets of
the Class C shares. The Class C shares' distribution fee may cause that Class to
have higher expenses and pay lower dividends than Class A or Class D shares. See
"Level Load Alternative--Class C Shares."
    
 
   
    CLASS D SHARES.  Class D shares are available only to limited categories of
investors (see "No Load Alternative--Class D Shares" below). Class D shares are
sold at net asset value with no initial sales charge or CDSC. They are not
subject to any 12b-1 fees. See "No Load Alternative--Class D Shares."
    
 
   
    SELECTING A PARTICULAR CLASS.  In deciding which Class of Fund shares to
purchase, investors should consider the following factors, as well as any other
relevant facts and circumstances:
    
 
   
    The decision as to which Class of shares is more beneficial to an investor
depends on the amount and intended length of his or her investment. Investors
who prefer an initial sales charge alternative may elect to purchase Class A
shares. Investors qualifying for 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 0.85% (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.
    
 
                                       21
<PAGE>
   
    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
    
 
                                       22
<PAGE>
   
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 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 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

    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 Dean Witter Trust Company ("DWTC") or Dean Witter Trust
FSB ("DWTFSB") (each of which is 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

to all of the terms and conditions of such programs, which may include
termination fees and restrictions on transferability of Fund shares);
    
 
   
   (3) retirement plans qualified under Section 401(k) of the Internal Revenue

DWR serves as recordkeeper;
    
 
   
   (4) 401(k) plans and other employer-sponsored plans qualified under Section
401(a) of the Internal Revenue Code for which DWTC or DWTFSB serves as Trustee

number of eligible employees;
    
 
   
   (5) 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
    
 
   
   (6) other categories of investors, at the discretion of the Board, as

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 (or, in the case of shares held by certain employer-sponsored benefit
plans, three years) preceding the redemption. In addition, Class B shares are
subject to an annual 12b-1 fee of 0.85% 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.
    
 
   
    Except as noted below, Class B shares of the Fund which are held for six
years or more after purchase (calculated from the last day of the month in which
the shares were purchased) will not be sub-
    
 
                                       24
<PAGE>
   
ject 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:

Code for which DWTC or DWTFSB serves as Trustee or the 401(k) Support Services
Group of DWR serves as recordkeeper and whose accounts are opened on or after
July 28, 1997, shares held for three years or more after purchase (calculated as
described in the paragraph above) will not be subject to any CDSC upon

    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 (or, in
the case of shares held by certain employer-sponsored benefit plans, three
years) preceding the redemption; (ii) the current net asset value of shares
purchased more than six years (or, in the case of shares held by certain
employer-sponsored benefit plans, three years) prior to the redemption; and
(iii) the current net asset value of shares purchased through reinvestment of
dividends or distributions and/or shares acquired in exchange for shares of FSC
Funds or of other Dean Witter Funds acquired in exchange for such shares.
Moreover, in determining whether a CDSC is applicable it will be assumed that
amounts described in (i), (ii) and (iii) above (in that order) are redeemed
first.
    
 
   
    In addition, the CDSC, if otherwise applicable, will be waived in the case
of:
    
 
   
   (1) redemptions of shares held at the time a shareholder dies or becomes
disabled, only if the shares are:  (A) registered either in the name of an
individual shareholder (not a trust), or in the names of such shareholder and
his or her spouse as joint tenants with right of survivorship; or  (B) held in a
qualified corporate or self-employed retirement plan, Individual Retirement
Account ("IRA") or Custodial Account under Section 403(b)(7) of the Internal
Revenue Code ("403(b) Custodial Account"), provided in either case that the
redemption is requested within one year of the death or initial determination of
disability;
    
 
   
   (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; and
    
 
   
   (3) all redemptions of shares held for the benefit of a participant in a
401(k) plan or other employer-sponsored plan qualified under Section 401(a) of
the Internal Revenue Code which offers investment
    
 
                                       25

companies managed by the Investment Manager or its subsidiary, Dean Witter
Services Company Inc., as self-directed investment alternatives and for which
DWTC or DWTFSB serves as Trustee or the 401(k) Support Services Group of DWR
serves as recordkeeper ("Eligible Plan"), provided that either:  (a) the plan
continues to be an Eligible Plan after the redemption; or  (b) the redemption is
in connection with the complete termination of the plan involving the
distribution of all plan assets to participants.
    
 
   
    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 held by a 401(k) plan or other employer-sponsored plan
qualified under Section 401(a) of the Internal Revenue Code and for which DWTC
or DWTFSB serves as Trustee or the 401(k) Support Services Group of DWR serves
as recordkeeper, the plan is treated as a single investor and all Class B shares
will convert to Class A shares on the conversion date of the first shares of a
Dean Witter Multi-Class Fund purchased by that plan. 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
    
 
                                       26
<PAGE>
   
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.
    
 
   
    Class B shares purchased before July 28, 1997 by trusts for which DWTC or
DWTFSB provides discretionary trustee services will convert to Class A shares on
or about August 29, 1997. The CDSC will not be applicable to such shares.
    
 
   
LEVEL LOAD ALTERNATIVE--CLASS C SHARES
    
 
   
    Class C shares are sold at net asset value next determined without an
initial sales charge but are subject to a CDSC of 1.0% on most redemptions made
within one year after purchase (calculated from the last day of the month in
which the shares were purchased). The CDSC will be assessed on an amount equal
to the lesser of the current market value or the cost of the shares being
redeemed. The CDSC will not be imposed in the circumstances set forth above in
the section "Contingent Deferred Sales Charge Alternative--Class B Shares--CDSC
Waivers," except that the references to six years in the first paragraph of that
section shall mean one year in the case of Class C shares. Class C shares are
subject to an annual 12b-1 fee of up to 0.85% 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 or administrative services (subject to all
of the terms and conditions of such programs, which may include termination fees
and restrictions on transferability of Fund shares); (iii) 401(k) plans
established by DWR and SPS Transaction Services, Inc. (an affiliate of DWR) for
their employees; (iv) certain Unit Investment Trusts sponsored by DWR; (v)
certain other open-end investment companies whose shares are distributed by the
Distributor; and (vi) 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 0.85% 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,
    
 
                                       27
<PAGE>
   
which is accrued daily and paid monthly, at the annual rate of 0.85% 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 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 October 31, 1996, Class B shares of the Fund
accrued payments under the Plan amounting to $1,058,190, which amount is equal
to 0.85% of the Fund's average daily net assets for the fiscal year. The
payments accrued under the Plan 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.
    
 
   
    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
$8,308,200 at October 31, 1996, which was equal to 7.29% of the net assets of
the Fund 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 0.85% of the aver-
    
 
                                       28
<PAGE>
   
age daily net assets of Class A or Class C, respectively, will not be reimbursed
by the Fund through payments in any subsequent year, except that expenses
representing a gross sales commission credited to account executives at the time
of sale may be reimbursed in the subsequent calendar year. 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 (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 by taking the net assets of the Fund, dividing by the number of shares
outstanding and adjusting to the nearest cent. The assets belonging to the Class
A, Class B, Class C and Class D shares will be invested together in a single
portfolio. The net asset value of each Class, however, will be determined
separately by subtracting each Class's accrued expenses and liabilities. The net
asset value per share will not be determined on Good Friday and on such other
federal and non-federal holidays as are observed by the New York Stock Exchange.
    
 
    In the calculation of the Fund's net asset value: (1) an equity portfolio
security listed or traded on the New York or American Stock Exchange or other
domestic or foreign stock exchange is valued at its latest sale price on that
exchange prior to the time when assets are valued (if there were no sales that
day, the security is valued at the latest bid price; in cases where securities
are traded on more than one exchange, the securities are valued on the exchange
designated as the primary market pursuant to procedures adopted by the
Trustees); and (2) all other portfolio securities for which over-the-counter
market quotations are readily available are valued at the latest available bid
price prior to the time of valuation. When market quotations are not readily
available, including circumstances under which it is determined by the
Investment Manager that sale and bid prices are not reflective of a security's
market value, portfolio securities are valued at their fair value as determined
in good faith under procedures established by and under the general supervision
of the Fund's Trustees. For valuation purposes, quotations of foreign portfolio
securities, other assets and liabilities and forward contracts stated in foreign
currency are translated into U.S. dollar equivalents at the prevailing market
rates prior to the close of the New York Stock Exchange.
 
    Short-term debt securities with remaining maturities of sixty days or less
at the time of purchase are valued at amortized cost, unless the Trustees
determine such does not reflect the securities' market value, in which case
these securities will be valued at their fair value as determined by the
Trustees.
 
    Certain of the Fund's portfolio securities may be valued by an outside
pricing service approved by the Fund's Trustees. The pricing service may utilize
a matrix system incorporating security quality, maturity and coupon as the
evaluation model parameters, and/or research evaluations by its staff, including
review of broker-dealer market price quotations, in determining what it believes
is the fair valuation of the portfolio securities valued by such pricing
service.
 
    Generally, trading in foreign securities, as well as corporate bonds, United
States government securities and money market instruments, is substantially
completed each day at various times prior to the close of the New York Stock
Exchange. The values of such securities used in computing the net asset value of
the Fund's shares are determined as of such times. Foreign currency exchange
rates are also generally determined prior to the close of the New York Stock
Exchange. Occasionally, events which affect the values of such securities and
such exchange rates may occur between the times at which they are determined and
the close of the New York Stock Exchange and will therefore not be
 
                                       29
<PAGE>
reflected in the computation of the Fund's net asset value. If events materially
affecting the value of such securities occur during such period, then these
securities will be valued at their fair value as 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 that they be paid in cash. Shares so acquired are acquired at net asset
value and are not subject to the imposition of a front-end sales charge or a
CDSC (see "Redemptions and Repurchases").
    
 
   
    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 Repurchases --
Involuntary Redemption").
    
 
   
    INVESTMENT OF DIVIDENDS AND DISTRIBUTIONS RECEIVED IN CASH.  Any shareholder
who receives a cash payment representing a dividend or capital gains
distribution may invest such dividend or distribution in shares of the
applicable Class at the net asset value per share next determined after receipt
by the Transfer Agent, by returning the check or the proceeds to the Transfer
Agent within thirty days after the payment date. Shares so acquired are acquired
at net asset value and are not subject to the imposition of a front-end sales
charge or a CDSC (see "Redemptions and Repurchases.")
    
 
   
    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 balance, on an annualized basis. Any applicable CDSC
will be imposed on shares redeemed under the Withdrawal Plan (see "Purchase of
Fund Shares"). Therefore, any shareholder participating in the Withdrawal Plan
will have sufficient shares redeemed from his or her account so that the
proceeds (net of any applicable CDSC) to the shareholder will be the designated
monthly or quarterly amount. Withdrawal plan payments should not be considered
as dividends, yields or income. If periodic withdrawal plan payments
continuously exceed net investment income and net capital gains, the
shareholder's original investment will be correspondingly reduced and ultimately
exhausted. Each withdrawal constitutes a redemption of shares and any gain or
loss realized must be recognized for federal income tax purposes.
    
 
    Shareholders should contact their DWR or other Selected Broker-Dealer
account executive or the Transfer Agent for further information about any of the
above services.
 
    TAX-SHELTERED RETIREMENT PLANS.  Retirement plans are available for use by
corporations, the self-employed, Individual Retirement Accounts and Custodial
Accounts under Section 403(b)(7) of the Internal Revenue Code. Adoption of such
plans should be on advice of legal counsel or tax adviser.
 
    For further information regarding plan administration, custodial fees and

Agent.

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., Dean Witter High Income Securities and Dean Witter National Municipal
Trust, which are Dean Witter Funds offered with a CDSC ("CDSC Funds"). 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, any CDSC
Fund 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 or CDSC Funds or any Exchange Fund that is
not a money market fund can be effected on the same basis.
    
 
   
    No CDSC is imposed at the time of any exchange of shares, although any
applicable CDSC will be imposed upon ultimate redemption. During the period of
time the shareholder remains in an Exchange Fund (calculated from the last day
of the month in which the Exchange Fund shares were acquired), the holding
period (for the purpose of determining the rate of the CDSC) is frozen. If those
shares are subsequently re-exchanged for shares of a Dean Witter Multi-Class
Fund or shares of a CDSC Fund, 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 a CDSC Fund 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 a CDSC
Fund (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. 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. (Exchange Fund 12b-1
distribution fees are described in the prospectuses for those funds.) Class B
shares of the Fund acquired in exchange for Class B shares of another Dean
Witter Multi-Class Fund or shares of a CDSC 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 EXPENSES. Purchases and exchanges should be
made for investment purposes only. A pattern of frequent
    
 
                                       31
<PAGE>
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
have been 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 the margin account.
 
   
    The current prospectus for each fund describes its investment objective(s)
and policies, and shareholders should obtain a copy and examine 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 may realize 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. 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 account executive (no Exchange Privilege
Authorization Form is required). Other shareholders (and those shareholders who
are clients of DWR or another Selected Broker-Dealer but who wish to make
exchanges directly by writing or telephoning the Transfer Agent) must complete
and forward to the Transfer Agent an Exchange Privilege Authorization Form,
copies of which may be obtained from the Transfer Agent, to initiate an
exchange. If the Authorization Form is used, exchanges may be made 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 fradulent instructions.
 
    Telephone exchange instructions will be accepted if received by the Transfer
Agent between 9:00 a.m. and 4:00 p.m. New York time, on any day the New York
Stock Exchange is open. Any shareholder wishing to make an exchange who has
previously filed an Exchange Privilege Authorization Form and who is unable to
reach the Fund by telephone should contact his or her DWR or other
 
                                       32
<PAGE>
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.
 
    Shareholders should contact their DWR or other Selected Broker-Dealer
account executive or the Transfer Agent for further information about the
Exchange Privilege.
 
REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 
   
    REDEMPTION.  Shares of each Class of the Fund can be redeemed for cash at
any time at the net asset value per share next determined less the amount of any
applicable CDSC in the case of Class A, Class B or Class C shares (see "Purchase
of Fund Shares"). If shares are held in a shareholder's account without a share
certificate, a written request for redemption to the Fund's Transfer Agent at
P.O. Box 983, Jersey City, NJ 07303 is required. If certificates are held by the
shareholder, the shares may be redeemed by surrendering the certificates with a
written request for redemption along with any additional information required by
the Transfer Agent.
    
 
   
    REPURCHASE.  DWR and other Selected Broker-Dealers are authorized to
repurchase shares represented by a share certificate which is delivered to any
of their offices. Shares held in a shareholder's account without a share
certificate may also be repurchased by DWR and other Selected Broker-Dealers
upon the telephonic request of the shareholder. The repurchase price is the net
asset value next computed (see "Purchase of Fund Shares") after such repurchase
order is received by DWR or other Selected Broker-Dealer, reduced by any
applicable CDSC.
    
 
   
    The CDSC, if any, will be the only fee imposed by the Fund or the
Distributor. The offer by DWR and other Selected Broker-Dealers to repurchase
shares 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 another Selected
Broker-Dealer are referred to their account executive regarding restrictions on
redemption of shares of the Fund pledged in the margin account.
 
   
    REINSTATEMENT PRIVILEGE.  A shareholder who has had his or her 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 net asset value next determined after a reinstatement request,
together with the proceeds, is received by the Transfer Agent and receive a pro
rata credit for any CDSC paid in connection with such redemption or repurchase.
    
 
    INVOLUNTARY REDEMPTION.  The Fund reserves the right, on sixty days' notice,
to redeem at their net asset value, the shares of any shareholder (other than
shares held in an Individual Retirement Account or Custodial Account under
Sec-
 
                                       33
<PAGE>
tion 403(b)(7) of the Internal Revenue Code) whose shares due to redemptions by
the shareholder have a value of less than $100 or such lesser amount as may be
fixed by the Trustees or, in the case of an account opened through EasyInvest,
if after twelve months the shareholder has invested less than $1,000 in the
account. However, before the Fund redeems such shares and sends the proceeds to
the shareholder, it will notify the shareholder that the value of the shares is
less than the applicable amount and allow the shareholder sixty days to make an
additional investment in an amount which will increase the value of 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 and intends to pay monthly income dividends and to
distribute net short-term and net long-term capital gains, if any, at least once
each year. The Fund may, however, determine either to distribute or to retain
all or part of any long-term capital gains in any year for reinvestment.
    
 
   
    All dividends and any capital gains distributions will be paid in additional
shares of the same Class and automatically credited to the shareholder's account
without issuance of a share certificate unless the shareholder requests in
writing that all dividends and/or distributions 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".)
    
 
    TAXES.  Because the Fund intends to distribute all of its net investment
income and net short-term and long-term capital gains to shareholders and remain
qualified as a regulated investment company under Subchapter M of the Code, it
is not expected that the Fund will be required to pay any federal income tax on
such income and capital gains.
 
    Gains or losses on the Fund's transactions in certain listed options on
securities and on futures and options on futures generally are treated as 60%
long-term gain/loss and 40% short-term gain/loss. When the Fund engages in
options and futures transactions, various tax regulations applicable to the Fund
may have the effect of causing the Fund to recognize a gain or loss for tax
purposes before that gain or loss is realized, or to defer recognition of a
realized loss for tax purposes. Recognition, for tax purposes, of an unrealized
loss may result in a lesser amount of the Fund's realized net gains being
available for distribution.
 
   
    As a regulated investment company, the Fund is subject to the requirement
that less than 30% of its gross income be derived from the sale of certain
investments held for less than three months (the "Short-Short Test"). The
treatment of foreign currency gains and gains from options, futures and forward
contracts on foreign currencies is uncertain under the Short Short Test since it
is dependent on whether such gains are "directly related" to the "business of
investing in stock or securities (or options and futures with respect to stock
or securities)." Although the Fund believes that its activities in foreign
currencies and options, futures and forward contracts on foreign currencies will
satisfy the "directly related" standard, the Treasury and the Internal Revenue
Service have not yet addressed the scope of the term "directly related." As a
result, there can be no assurance that future Treasury regulations or rulings
issued by the Internal Revenue Service will not adopt a restrictive meaning for
the term "directly related." In such a case, the Fund's
    
 
                                       34
<PAGE>
activities in foreign currencies and options, futures and forward contracts on
foreign currencies would be restricted. Further, if such regulations or rulings
are adopted on a retroactive basis, and if, as a result, the Fund fails to
satisfy the "Short Short Test", the Fund might be retroactively disqualified as
a regulated investment company and the Fund might have to pay a federal
corporate income tax on its net investment income and net capital gains.
 
   
    Shareholders will normally have to pay federal income taxes, and any
applicable state and/or local income taxes, on the dividends and distributions
they receive from the Fund. Such dividends and distributions, to the extent that
they are derived from net investment income and net short-term capital gains,
are taxable to the shareholder as ordinary dividend income regardless of whether
the shareholder receives such distributions in additional shares or in cash. 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, for tax purposes, to have
been received by the shareholder in the prior year.
    
 
    Distributions of net long-term capital gains, if any, are taxable to
shareholders as long-term capital gains regardless of how long a shareholder has
held the Fund's shares and regardless of whether the distribution is received in
additional shares or in cash.
 
    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.
 
    After the end of the calendar year, shareholders will be sent full
information on their dividends and capital gains distributions for tax purposes,
including information as to the portion taxable as ordinary income and the
portion taxable as long-term capital gains.
 
    To avoid being subject to a 31% federal backup withholding tax on taxable
dividends, capital gains distributions and the proceeds of redemptions and
repurchases, shareholders' taxpayer identification numbers must be furnished and
certified as to their accuracy.
 
    Dividends, interest and gains received by the Fund may give rise to
withholding and other taxes imposed by foreign countries. If it qualifies for
and has made the appropriate election with the Internal Revenue Service, the
Fund will report annually to its shareholders the amount per share of such
taxes, to enable shareholders to claim United States foreign tax credits or
deductions with respect to such taxes. In the absence of such an election, the
Fund would deduct foreign tax in computing the amount of its distributable
income.
 
    The foregoing discussion relates solely to the federal income tax
consequences of an investment in the Fund. Distributions may also be subject to
state and local taxes; therefore, each shareholder is advised to consult his or
her own tax adviser.
 
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 "average annual total return" of the Fund refers to a figure reflecting
the average annualized
 
                                       35
<PAGE>
   
percentage increase (or decrease) in the value of an initial investment in a
Class of the Fund of $1,000 over periods of one, five and ten years, as well as
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, and
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. and Salomon Brothers Treasury Index, Salomon Brothers
World Government Index, Salomon Brothers Corporate Index, Shearson Lehman
Corporate/Government Bond Index and Donahue's Money Market Index).
    
 
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 in
ordinary circumstances the Fund does not intend to hold such meetings. The
Trustees may call Special Meetings of Shareholders for action by shareholder
vote as may be required by the Act or the Declaration of Trust. Under certain
circumstances the Trustees may be removed by action of the Trustees or by the
shareholders.
 
    Under Massachusetts law, shareholders of a business trust may, under certain
circumstances, be held personally liable as partners for 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
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
 
                                       36
<PAGE>
conflicts of interest are avoided. To achieve these goals and comply with
regulatory requirements, the Code of Ethics requires, among other things, that
personal securities transactions by employees of the companies be subject to an
advance clearance process to monitor that no Dean Witter Fund is engaged at the
same time in a purchase or sale of the same security. The Code of Ethics bans
the purchase of securities in an initial public offering, and also prohibits
engaging in futures and options transactions and profiting on short-term trading
(that is, a purchase within sixty days of a sale or a sale within sixty days of
a purchase) of a security. In addition, investment personnel may not purchase or
sell a security for their personal account within thirty days before or after
any transaction in any Dean Witter Fund managed by them. Any violations of the
Code of Ethics are subject to sanctions, including reprimand, demotion or
suspension or termination of employment. The Code of Ethics comports with
regulatory requirements and the recommendations in the 1994 report by the
Investment Company Institute Advisory Group on Personal Investing.
 
   
    MASTER/FEEDER CONVERSION.  The Fund reserves the right to seek to achieve
its investment objectives by investing all of its investable assets in a
non-diversified, open-end management investment company having the same
investment objectives 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
 
    The Fund is a Trust of the type commonly known as a "Massachusetts business
trust" and was organized under the laws of the Commonwealth of Massachusetts on

THE INVESTMENT MANAGER
 
   
    Dean Witter InterCapital Inc. (the "Investment Manager" or "InterCapital"),
a Delaware corporation, 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, Discover & Co. ("MSDWD"), a Delaware

InterCapital assumed the investment advisory, administrative and management
activities previously performed by the InterCapital Division of Dean Witter

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 is conducted by or under the
direction of officers of the Fund and of the Investment Manager, subject to
review by the Fund's Board of Trustees. Information as to these Trustees and

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 Core Equity
Trust, TCW/DW North American Government Income Trust, TCW/DW Latin American

company; (ii) administrator of The BlackRock Strategic Term Trust Inc., a
closed-end investment company; and (iii) sub-administrator of MassMutual
Participation Investors and Templeton Global Governments Income Trust,

    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 objectives.
 
    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 and bookkeeping and certain legal services as the Fund
may reasonably require in the conduct of its business, including the preparation
of prospectuses, statements of additional information, 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. The expenses borne by the
Fund include, but are not limited to: expenses of the Plan of Distribution
pursuant to Rule 12b-1 (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 of share
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
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
    
 
                                       4

Manager or any corporate affiliate of the Investment Manager; all expenses
incident to any dividend, withdrawal or redemption options; charges and expenses
of any outside service used for pricing of the Fund's shares; fees and expenses
of legal counsel, including counsel to the Trustees who are not interested
persons of the Fund or of the Investment Manager (not including compensation or
expenses of attorneys who are employees of the Investment Manager) 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 at an annual rate of
0.75% of the daily net assets of the Fund up to $250 million; 0.60% of the
portion of the daily net assets of the Fund exceeding $250 million but not
exceeding $500 million; 0.50% of the portion of the daily net assets of the Fund
exceeding $500 million but not exceeding $750 million; 0.40% of the portion of
the daily net assets of the Fund exceeding $750 million but not exceeding $1
billion; and 0.30% of the daily net assets of the Fund exceeding $1 billion. For
the fiscal years ended October 31, 1994, 1995 and 1996, the Fund accrued to the
Investment Manager total compensation in the amounts of $1,674,474, $1,169,823,
and $933,697, 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 in no way restricts 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 30, 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 had an initial term ending April 30, 1999,
and will remain 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 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 (the "Independent Trustees"), which vote must be cast in person
at a meeting called for the purpose of voting on such approval.
    
 
   
    The Fund has acknowledged that the name "Dean Witter" is a property right of
DWR. The Fund has agreed that DWR or its parent company may use, or at any time
permit others to use, the name "Dean Witter." The Fund has also agreed that in
the event the Agreement is terminated, or if the affiliation between
InterCapital and its parent company is terminated, the Fund will eliminate the
name "Dean Witter" from its name if DWR or its parent company shall so request.

THE BOARD OF TRUSTEES, THE INDEPENDENT TRUSTEES, AND THE COMMITTEES
 
   
    The Board of Trustees currently consists of eight (8) trustees; as noted
above, Mr. Hedien's term will commence on September 1, 1997. 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 83 Dean Witter Funds,
comprised of 126 portfolios. As of June 30, 1997, the Dean Witter Funds had
total net assets of approximately $     billion and more than six million
shareholders.
    
 
   
    Six Trustees and Mr. Hedien (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 InterCapital's parent company,
MSDWD. These are the "disinterested" or "independent" Trustees. The other two
Trustees (the "management Trustees") are affiliated with InterCapital. Four of
the six 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 current 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, 1996, the three Committees held a combined total of sixteen
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
    
 
                                       9
<PAGE>
   
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, management 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, since July
1, 1996, 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 $1,000 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). 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.
    
 
    The following table illustrates the compensation paid to the Fund's
Independent Trustees by the Fund for the fiscal year ended October 31, 1996.

    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 October 31,
1996 and by the 57 Dean Witter Funds (including the Fund) for the year ended
December 31, 1996, and the estimated retirement benefits for the Fund's
Independent Trustees, to commence upon their retirement, from the Fund as of
October 31, 1996 and from the 57 Dean Witter Funds as of December 31, 1996.
    
- ------------------------
 
   
(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
- --------------------------------------------------------------------------------
 
CONVERTIBLE SECURITIES
 
    The Fund may invest in fixed-income securities which are convertible into
common stock. Convertible securities rank senior to common stocks in a
corporation's capital structure and, therefore, entail less risk than the
corporation's common stock. The value of a convertible security is a function of
its "investment value" (its value as if it did not have a conversion privilege),
and its "conversion value" (the security's worth if it were to be exchanged for
the underlying security, at market value, pursuant to its conversion privilege).
 
    To the extent that a convertible security's investment value is greater than
its conversion value, its price will be primarily a reflection of such
investment value and its price will be likely to increase when interest rates
fall and decrease when interest rates rise, as with a fixed-income security (the
credit standing of the issuer and other factors may also have an effect on the
convertible security's value). If the conversion value exceeds the investment
value, the price of the convertible security will rise above its investment
value and, in addition, will sell at some premium over its conversion value.
(This premium represents the price investors are willing to pay for the
privilege of purchasing a fixed-income security with a possibility of capital
appreciation due to the conversion privilege.) At such times the price of the
convertible security will tend to fluctuate directly with the price of the
underlying equity security. Convertible securities may be purchased by the Fund
at varying price levels above their investment values and/or their conversion
values in keeping with the Fund's objectives.
 
WARRANTS
 
    The Fund may acquire warrants which are attached to fixed-income securities
purchased for its portfolio and hold such warrants until the Investment Manager
determines it is prudent to sell. Warrants are, in effect, an option to purchase
equity securities at a specific price, generally valid for a specific period of
time, and have no voting rights, pay no dividends and have no rights with
respect to the corporations issuing them. If warrants remain unexercised at the
end of the exercise period, they will lapse and the Fund's investment in them
will be lost. The prices of warrants do not necessarily move parallel to the
prices of the underlying securities.
 
                                       12
<PAGE>
U.S. GOVERNMENT SECURITIES
 
    Securities issued by the U.S. Government, its agencies or instrumentalities
in which the Fund may invest include:
 
        (1) U.S. Treasury bills (maturities of one year or less), U.S. Treasury
    notes (maturities of one to ten years) and U.S. Treasury bonds (generally
    maturities of greater than ten years), all of which are direct obligations
    of the U.S. Government and, as such, are backed by the "full faith and
    credit" of the United States.
 
        (2) Securities issued by agencies and instrumentalities of the U.S.
    Government which are backed by the full faith and credit of the United
    States. Among the agencies and instrumentalities issuing such obligations
    are the Federal Housing Administration, the Government National Mortgage
    Association ("GNMA"), the Department of Housing and Urban Development, the
    Export-Import Bank, the Farmers Home Administration, the General Services
    Administration, the Maritime Administration and the Small Business
    Administration. The maturities of such obligations range from three months
    to 30 years.
 
        (3) Securities issued by agencies and instrumentalities which are not
    backed by the full faith and credit of the United States, but whose issuing
    agency or instrumentality has the right to borrow, to meet its obligations,
    from an existing line of credit with the U.S. Treasury. Among the agencies
    and instrumentalities issuing such obligations are the Tennessee Valley
    Authority, the Federal National Mortgage Association ("FNMA"), the Federal
    Home Loan Mortgage Corporation ("FHLMC") and the U.S. Postal Service.
 
        (4) Securities issued by agencies and instrumentalities which are not
    backed by the full faith and credit of the United States, but which are
    backed by the credit of the issuing agency or instrumentality. Among the
    agencies and instrumentalities issuing such obligations are the Federal Farm
    Credit System and the Federal Home Loan Banks.
 
    Neither the value nor the yield of the U.S. Government securities which may
be invested in by the Fund is guaranteed by the U.S. Government. Such values and
yield will fluctuate with changes in prevailing interest rates and other
factors. Generally, as prevailing interest rates rise, the value of any U.S.
Government securities held by the Fund will fall. Such securities with longer
maturities generally tend to produce higher yields and are subject to greater
market fluctuation as a result of changes in interest rates than debt securities
with shorter maturities.
 
ZERO COUPON TREASURY SECURITIES
 
    A portion of the U.S. Government securities purchased by the Fund may be
"zero coupon" Treasury securities. These are U.S. Treasury bills, notes and
bonds which have been stripped of their unmatured interest coupons and receipts
or which are certificates representing interests in such stripped debt
obligations and coupons. Such securities are purchased at a discount from their
face amount, giving the purchaser the right to receive their full value at
maturity. A zero coupon security pays no interest to its holder during its life.
Its value to an investor consists of the difference between its face value at
the time of maturity and the price for which it was acquired, which is generally
an amount significantly less than its face value (sometimes referred to as a
"deep discount" price). The Fund intends to invest in such zero coupon treasury
securities as STRIPS, Treasury Receipts, Physical Coupons, and Proprietary
Receipts.
 
    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 if
prevailing interest rates rise. For this reason, zero coupon securities are
subject to substantially greater market price fluctuations during periods of
changing prevailing interest rates than are comparable debt securities which
make current distributions of interest. 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.
 
                                       13
<PAGE>
    Currently the only U.S. Treasury security issued without coupons is the
Treasury bill. However, in the last few years a number of banks and brokerage
firms have separated ("stripped") the principal portions from the coupon
portions of the U.S. Treasury bonds and notes and sold them separately in the
form of receipts or certificates representing undivided interests in these
instruments (which instruments are generally held by a bank in a custodial or
trust account).
 
MONEY MARKET INSTRUMENTS
 
    As stated in the Prospectus, the money market instruments which the Fund may
purchase include U.S. Government securities, bank obligations, Eurodollar
certificates of deposit, obligations of savings institutions, fully insured
certificates of deposit and commercial paper. Such securities are limited to:
 
    U.S. GOVERNMENT SECURITIES.  Obligations issued or guaranteed as to
principal and interest by the United States or its agencies (such as the
Export-Import Bank of the United States, Federal Housing Administration and
Government National Mortgage Association) or its instrumentalities (such as the
Federal Home Loan Bank), including Treasury bills, notes and bonds;
 
    BANK OBLIGATIONS.  Obligations (including certificates of deposit and
bankers' acceptances) of banks subject to regulation by the U.S. Government and
having total assets of $1,000,000,000 or more, and instruments secured by such
obligations, not including obligations of foreign branches of domestic banks
except to the extent below;
 
    EURODOLLAR CERTIFICATES OF DEPOSIT.  Eurodollar certificates of deposit
issued by foreign branches of domestic banks having total assets of
$1,000,000,000 or more;
 
    OBLIGATIONS OF SAVINGS INSTITUTIONS.  Certificates of deposit of savings
banks and savings and loan associations, having total assets of $1,000,000,000
or more;
 
    FULLY INSURED CERTIFICATES OF DEPOSIT.  Certificates of deposit of banks and
savings institutions, having total assets of less than $1,000,000,000, if the
principal amount of the obligation is insured by the Bank Insurance Fund or the
Savings Association Insurance Fund (each of which is administered by the Federal
Deposit Insurance Corporation), limited to $100,000 principal amount per
certificate and to 10% or less of the Fund's total assets in all such
obligations and in all illiquid assets, in the aggregate;
 
    COMMERCIAL PAPER.  Commercial paper rated within the two highest grades by
S&P or the highest grade by Moody's or, if not rated, issued by a company having
an outstanding debt issue rated at least AA by S&P or Aa by Moody's.
 
FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS
 
    As discussed in the Prospectus, the Fund may enter into forward foreign
currency exchange contracts ("forward contracts") as a hedge against
fluctuations in future foreign exchange rates. The Fund will conduct its foreign
currency exchange transactions either on a spot (i.e., cash) basis at the spot
rate prevailing in the foreign currency exchange market, or through entering
into forward contracts to purchase or sell foreign currencies. A forward
contract involves an obligation to purchase or sell a specific currency at a
future date, which may be any fixed number of days from the date of the contract
agreed upon by the parties, at a price set at the time of the contract. These
contracts are traded in the interbank market conducted directly between currency
traders and their customers. Such forward contracts will only be entered into
with United States banks and their foreign branches, insurance companies and
other dealers whose assets total $1 billion or more or foreign banks whose
assets total $1 billion or more. A forward contract generally has no deposit
requirement, and no commissions are charged at any stage for trades.
 
    When management of the Fund believes that the currency of a particular
foreign country may suffer a substantial movement against the U.S. dollar, it
may enter into a forward contract to purchase or sell, for a fixed amount of
dollars or other currency, the amount of foreign currency approximating the
value of some or all of the Fund's portfolio securities denominated in such
foreign currency. The Fund
 
                                       14
<PAGE>
will not enter into such forward contracts or maintain a net exposure to such
contracts where the consummation of the contracts would obligate the Fund to
deliver an amount of foreign currency in excess of the value of the Fund's
portfolio securities or other assets denominated in that currency. Under normal
circumstances, consideration of the prospect for currency parities will be
incorporated into the longer term investment decisions made with regard to
overall diversification strategies. However, the Investment Manager believes
that it is important to have the flexibility to enter into such forward
contracts when it determines that the best interests of the Fund will be served.
The Fund's custodian bank will place cash, U.S. Government securities, high
grade debt securities or other liquid securities in a segregated account of the
Fund in an amount equal to the value of the Fund's total assets committed to the
consummation of forward contracts entered into under the circumstances set forth
above. If the value of the securities placed in the segregated account declines,
additional cash or securities will be placed in the account on a daily basis so
that the value of the account will equal the amount of the Fund's commitments
with respect to such contracts.
 
    Where, for example, the Fund is hedging a portfolio position consisting of
foreign fixed-income securities denominated in a foreign currency against
adverse exchange rate moves vis-a-vis the U.S. dollar, at the maturity of the
forward contract for delivery by the Fund of a foreign currency, the Fund may
either sell the portfolio security and make delivery of the foreign currency, or
it may retain the security and terminate its contractual obligation to deliver
the foreign currency by purchasing an "offsetting" contract with the same
currency trader obligating it to purchase, on the same maturity date, the same
amount of the foreign currency. It is impossible to forecast the market value of
portfolio securities at the expiration of the contract. Accordingly, it may be
necessary for the Fund to purchase additional foreign currency on the spot
market (and bear the expense of such purchase) if the market value of the
security is less than the amount of foreign currency the Fund is obligated to
deliver and if a decision is made to sell the security and make delivery of the
foreign currency. Conversely, it may be necessary to sell on the spot market
some of the foreign currency received upon the sale of the portfolio securities
if its market value exceeds the amount of foreign currency the Fund is obligated
to deliver.
 
    If the Fund retains the portfolio securities and engages in an offsetting
transaction, the Fund will incur a gain or loss to the extent that there has
been movement in spot or forward contract prices. If the Fund engages in an
offsetting transaction, it may subsequently enter into a new forward contract to
sell the foreign currency. Should forward prices decline during the period
between the Fund's entering into a forward contract for the sale of a foreign
currency and the date it enters into an offsetting contract for the purchase of
the foreign currency, the Fund will realize a gain to the extent the price of
the currency it has agreed to sell exceeds the price of the currency it has
agreed to purchase. Should forward prices increase, the Fund will suffer a loss
to the extent the price of the currency it has agreed to purchase exceeds the
price of the currency it has agreed to sell.
 
    If the Fund purchases a fixed-income security which is denominated in U.S.
dollars but which will pay out its principal based upon a formula tied to the
exchange rate between the U.S. dollar and a foreign currency, it may hedge
against a decline in the principal value of the security by entering into a
forward contract to sell an amount of the relevant foreign currency equal to
some or all of the principal value of the security.
 
   
    At times when the Fund has written a call or put option on a fixed-income
security or the currency in which it is denominated, it may wish to enter into a
forward contract to purchase or sell the foreign currency in which the security
is denominated. A forward contract would, for example, hedge the risk of the
security on which a call currency option has been written declining in value to
a greater extent than the value of the premium received for the option. The Fund
will maintain with its Custodian at all times, cash, U.S. Government securities,
or other liquid portfolio securities in a segregated account equal in value to
all forward contract obligations and option contract obligations entered into in
hedge situations such as this.
    
 
    Although the Fund values its assets daily in terms of U.S. dollars, it does
not intend to convert its holdings of foreign currencies into U.S. dollars on a
daily basis. It will, however, do so from time to time,
 
                                       15
<PAGE>
and investors should be aware of the costs of currency conversion. Although
foreign exchange dealers do not charge a fee for conversion, they do realize a
profit based on the spread between the prices at which they are buying and
selling various currencies. Thus, a dealer may offer to sell a foreign currency
to the Fund at one rate, while offering a lesser rate of exchange should the
Fund desire to resell that currency to the dealer.
 
OPTIONS AND FUTURES TRANSACTIONS
 
    As discussed in the Prospectus, the Fund may write covered call options
against securities held in its portfolio and covered put options on eligible
portfolio securities and stock indexes and purchase options of the same series
to effect closing transactions, and may hedge against potential changes in the
market value of investments (or anticipated investments) and facilitate the
reallocation of the Fund's assets into and out of equities and fixed-income
securities by purchasing put and call options on portfolio (or eligible
portfolio) securities and engaging in transactions involving futures contracts
and options on such contracts.
 
    Call and put options on U.S. Treasury notes, bonds and bills and equity
securities are listed on Exchanges (currently the Chicago Board Options
Exchange, American Stock Exchange, New York Stock Exchange, Pacific Stock
Exchange and Philadelphia Stock Exchange) and are written in over-the-counter
transactions ("OTC Options"). Listed options are issued by the Options Clearing
Corporation ("OCC"). Ownership of a listed call option gives the Fund the right
to buy from the OCC the underlying security covered by the option at the stated
exercise price (the price per unit of the underlying security) by filing an
exercise notice prior to the expiration date of the option. The writer (seller)
of the option would then have the obligation to sell to the OCC the underlying
security at that exercise price prior to the expiration date of the option,
regardless of its then current market price. Ownership of a listed put option
would give the Fund the right to sell the underlying security to the OCC at the
stated exercise price. Upon notice of exercise of the put option, the writer of
the put would have the obligation to purchase the underlying security from the
OCC at the exercise price.
 
    OPTIONS ON TREASURY BONDS AND NOTES.  Because trading interest in options
written on Treasury bonds and notes tends to center on the most recently
auctioned issues, the exchanges on which such securities trade will not continue
indefinitely to introduce options with new expirations to replace expiring
options on particular issues. Instead, the expirations introduced at the
commencement of options trading on a particular issue will be allowed to run
their course, with the possible addition of a limited number of new expirations
as the original ones expire. Options trading on each issue of bonds or notes
will thus be phased out as new options are listed on more recent issues, and
options representing a full range of expirations will not ordinarily be
available for every issue on which options are traded.
 
    OPTIONS ON TREASURY BILLS.  Because a deliverable Treasury bill changes from
week to week, writers of Treasury bill calls cannot provide in advance for their
potential exercise settlement obligations by acquiring and holding the
underlying security. However, if the Fund holds a long position in Treasury
bills with a principal amount of the securities deliverable upon exercise of the
option, the position may be hedged from a risk standpoint by the writing of a
call option. For so long as the call option is outstanding, the Fund will hold
the Treasury bills in a segregated account with its Custodian, so that they will
be treated as being covered.
 
    OPTIONS ON GNMA CERTIFICATES.  Currently, options on GNMA Certificates are
only traded over-the-counter. Since the remaining principal balance of GNMA
Certificates declines each month as a result of mortgage payments, the Fund, as
a writer of a GNMA call holding GNMA Certificates as "cover" to satisfy its
delivery obligation in the event of exercise, may find that the GNMA
Certificates it holds no longer have a sufficient remaining principal balance
for this purpose. Should this occur, the Fund will purchase additional GNMA
Certificates from the same pool (if obtainable) or replacement GNMA Certificates
in the cash market in order to maintain its cover. A GNMA Certificate held by
the Fund to cover an option position in any but the nearest expiration month may
cease to represent cover for the option in the event of a decline in the GNMA
coupon rate at which new pools are originated under the FHA/VA loan ceiling in
effect at any given time, as such decline may increase the prepayments made on
 
                                       16
<PAGE>
other mortgage pools. If this should occur, the Fund will no longer be covered,
and the Fund will either enter into a closing purchase transaction or replace
such Certificate with a Certificate which represents cover. When the Fund closes
out its position or replaces such Certificate, it may realize an unanticipated
loss and incur transaction costs.
 
    OPTIONS ON FOREIGN CURRENCIES.  The Fund may purchase and write options on
foreign currencies for purposes similar to those involved with investing in
forward foreign currency exchange contracts. For example, in order to protect
against declines in the dollar value of portfolio securities which are
denominated in a foreign currency, the Fund may purchase put options on an
amount of such foreign currency equivalent to the current value of the portfolio
securities involved. As a result, the Fund would be enabled to sell the foreign
currency for a fixed amount of U.S. dollars, thereby "locking in" the dollar
value of the portfolio securities (less the amount of the premiums paid for the
options). Conversely, the Fund may purchase call options on foreign currencies
in which securities it anticipates purchasing are denominated to secure a set
U.S. dollar price for such securities and protect against a decline in the value
of the U.S. dollar against such foreign currency. The Fund may also purchase
call and put options to close out written option positions.
 
    The Fund may also write call options on foreign currency to protect against
potential declines in its portfolio securities which are denominated in foreign
currencies. If the U.S. dollar value of the portfolio securities falls as a
result of a decline in the exchange rate between the foreign currency in which
it is denominated and the U.S. dollar, then a loss to the Fund occasioned by
such value decline would be ameliorated by receipt of the premium on the option
sold. At the same time, however, the Fund gives up the benefit of any rise in
value of the relevant portfolio securities above the exercise price of the
option and, in fact, only receives a benefit from the writing of the option to
the extent that the value of the portfolio securities falls below the price of
the premium received. A put option on a foreign currency would be written by the
Fund for the same reason it would purchase a call option, namely, to hedge
against an increase in the U.S. dollar value of a foreign security which the
Fund anticipates purchasing. Here, the receipt of the premium would offset, to
the extent of the size of the premium, any increased cost to the Fund resulting
from an increase in the U.S. dollar value of the foreign security. However, the
Fund could not benefit from any decline in the cost of the foreign security
which is greater than the price of the premium received. The Fund may also write
options to close out long put and call option positions.
 
    The markets in foreign currency options are relatively new and the Fund's
ability to establish and close out positions on such options is subject to the
maintenance of a liquid secondary market. Although the Fund will not purchase or
write such options unless and until, in the Investment Manager's opinion, the
market for them has developed sufficiently to ensure that the risks in
connection with such options are not greater than the risks in connection with
the underlying currency, there can be no assurance that a liquid secondary
market will exist for a particular option at any specific time. In addition,
options on foreign currencies are affected by all of those factors which
influence foreign exchange rates and investments generally.
 
    The value of a foreign currency option depends upon the value of the
underlying currency relative to the U.S. dollar. As a result, the price of the
option position may vary with changes in the value of either or both currencies
and have no relationship to the investment merits of a foreign security,
including foreign securities held in a "hedged" investment portfolio. Because
foreign currency transactions occurring in the interbank market involve
substantially larger amounts than those that may be involved in the use of
foreign currency options, investors may be disadvantaged by having to deal in an
odd lot market (generally consisting of transactions of less than $1 million)
for the underlying foreign currencies at prices that are less favorable than for
round lots.
 
    There is no systematic reporting of last sale information for foreign
currencies or any regulatory requirement that quotations available through
dealers or other market sources be firm or revised on a timely basis. Quotation
information available is generally representative of very large transactions in
the interbank market and thus may not reflect relatively smaller transactions
(i.e., less than $1 million) where rates may be less favorable. The interbank
market in foreign currencies is a global, around-the-clock
 
                                       17
<PAGE>
market. To the extent that the U.S. options markets are closed while the markets
for the underlying currencies remain open, significant price and rate movements
may take place in the underlying markets that are not reflected in the options
market.
 
    OTC OPTIONS.  Exchange-listed options are issued by the OCC which assures
that all transactions in such options are properly executed. OTC options are
purchased from or sold (written) to dealers or financial institutions which have
entered into direct agreements with the Fund. With OTC options, such variables
as expiration date, exercise price and premium will be agreed upon between the
Fund and the transacting dealer, without the intermediation of a third party
such as the OCC. If the transacting dealer fails to make or take delivery of the
securities underlying an option it has written, in accordance with the terms of
that option, the Fund would lose the premium paid for the option as well as any
anticipated benefit of the transaction.
 
    COVERED CALL WRITING.  As stated in the Prospectus, the Fund is permitted to
write covered call options on portfolio securities and the currencies in which
they are denominated, without limit, in order to aid in achieving its investment
objectives. Generally, a call option is "covered" if the Fund owns, or has the
right to acquire, without additional cash consideration (or for additional cash
consideration held for the Fund by its Custodian in a segregated account) the
underlying security (currency) subject to the option except that in the case of
call options on U.S. Treasury Bills, the Fund might own U.S. Treasury Bills of a
different series from those underlying the call option, but with a principal
amount and value corresponding to the exercise price and a maturity date no
later than that of the security (currency) deliverable under the call option. A
call option is also covered if the Fund holds a call on the same security as the
underlying security (currency) of the written option, where the exercise price
of the call used for coverage is equal to or less than the exercise price of the
call written or greater than the exercise price of the call written if the mark
to market difference is maintained by the Fund in cash, U.S. Government
securities or other liquid portfolio securities which the Fund holds in a
segregated account maintained with its Custodian.
 
    The Fund will receive from the purchaser, in return for a call it has
written, a "premium"; i.e., the price of the option. Receipt of these premiums
may better enable the Fund to earn a higher level of current income than it
would earn from holding the underlying securities (currencies) alone. Moreover,
the premium received will offset a portion of the potential loss incurred by the
Fund if the securities (currencies) underlying the option are ultimately sold
(exchanged) by the Fund at a loss. The premium received will fluctuate with
varying economic market conditions. If the market value of the portfolio
securities (or the currencies in which they are denominated) upon which call
options have been written increases, the Fund may receive a lower total return
from the portion of its portfolio upon which calls have been written than it
would have had such calls not been written.
 
    As regards listed options and certain OTC options, during the option period,
the Fund may be required, at any time, to deliver the underlying security
(currency) against payment of the exercise price on any calls it has written
(exercise of certain listed and OTC options may be limited to specific
expiration dates). This obligation is terminated upon the expiration of the
option period or at such earlier time when the writer effects a closing purchase
transaction. A closing purchase transaction 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.
 
    Closing purchase transactions are ordinarily effected to realize a profit on
an outstanding call option, to prevent an underlying security (currency) from
being called, to permit the sale of an underlying security (or the exchange of
the underlying currency) or to enable the Fund to write another call option on
the underlying security (currency) with either a different exercise price or
expiration date or both. The Fund may realize a net gain or loss from a closing
purchase transaction depending upon whether the amount of the premium received
on the call option is more or less than the cost of effecting the closing
purchase transaction. Any loss incurred in a closing purchase transaction may be
wholly or partially
 
                                       18
<PAGE>
offset by unrealized appreciation in the market value of the underlying security
(currency). Conversely, a gain resulting from a closing purchase transaction
could be offset in whole or in part or exceeded by a decline in the market value
of the underlying security (currency).
 
    If a call option expires unexercised, the Fund realizes a gain in the amount
of the premium on the option less the commission paid. Such a gain, however, may
be offset by depreciation in the market value of the underlying security
(currency) during the option period. If a call option is exercised, the Fund
realizes a gain or loss from the sale of the underlying security (currency)
equal to the difference between the purchase price of the underlying security
(currency) and the proceeds of the sale of the security (currency) plus the
premium received for the option less the commission paid.
 
    Options written by the Fund will normally have expiration dates of up to
eighteen months from the date written. The exercise price of a call option may
be below, equal to or above the current market value of the underlying security
at the time the option is written. See "Risks of Options Transactions," below.
 
    COVERED PUT WRITING.  As stated in the Prospectus, as a writer of a covered
put option, the Fund incurs an obligation to buy the security underlying the
option from the purchaser of the put, at the option's exercise price at any time
during the option period, at the purchaser's election (certain listed and OTC
put options written by the Fund will be exercisable by the purchaser only on a
specific date). A put is "covered" if, at all times, the Fund maintains, in a
segregated account maintained on its behalf at the Fund's Custodian, cash, U.S.
Government securities or other liquid portfolio securities in an amount equal to
at least the exercise price of the option, at all times during the option
period. Similarly, a short put position could be covered by the Fund by its
purchase of a put option on the same security (currency) as the underlying
security of the written option, where the exercise price of the purchased option
is equal to or more than the exercise price of the put written or less than the
exercise price of the put written if the marked to market difference is
maintained by the Fund in cash, U.S. Government securities or other liquid
portfolio securities which the Fund holds in a segregated account maintained at
its Custodian. In writing puts, the Fund assumes the risk of loss should the
market value of the underlying security (currency) decline below the exercise
price of the option (any loss being decreased by the receipt of the premium on
the option written). In the case of listed options, during the option period,
the Fund may be required, at any time, to make payment of the exercise price
against delivery of the underlying security (currency). The operation of and
limitations on covered put options in other respects are substantially identical
to those of call options.
 
    The Fund will write put options for three purposes: (1) to receive the
income derived from the premiums paid by purchasers; (2) when the Investment
Manager wishes to purchase the security (or a security denominated in the
currency underlying the option) underlying the option at a price lower than its
current market price, in which case it will write the covered put at an exercise
price reflecting the lower purchase price sought; and (3) to close out a long
put option position. The potential gain on a covered put option is limited to
the premium received on the option (less the commissions paid on the
transaction) while the potential loss equals the differences between the
exercise price of the option and the current market price of the underlying
securities (currencies) when the put is exercised, offset by the premium
received (less the commissions paid on the transaction).
 
    PURCHASING CALL AND PUT OPTIONS.  As stated in the Prospectus, the Fund may
purchase listed and OTC call and put options in amounts equalling up to 5% of
its total assets. The Fund may purchase a call option in order to close out a
covered call position (see "Covered Call Writing" above), to protect against an
increase in price of a security it anticipates purchasing or, in the case of a
call option on foreign currency, to hedge against an adverse exchange rate move
of the currency in which the security it anticipates purchasing is denominated
vis-a-vis the currency in which the exercise price is denominated. If the price
of the security (or value of the currency in which it is denominated) underlying
the option fails to rise above the exercise price by an amount exceeding the
price of the option premium, the Fund will sustain a loss equal to some or all
of the premium price. The purchase of the call option to effect a closing
transaction on a call written over-the-counter may be a listed or an OTC option.
In either case, the
 
                                       19
<PAGE>
call purchased is likely to be on the same securities (currencies) and have the
same terms as the written option. If purchased over-the-counter, the option
would generally be acquired from the dealer or financial institution which
purchased the call written by the Fund.
 
    The Fund may purchase put options on securities (currencies) which it holds
in its portfolio only to protect itself against a decline in the value of the
security. If the value of the underlying security (currency) were to fall below
the exercise price of the put purchased in an amount greater than the premium
paid for the option, the Fund would incur no additional loss. The Fund may also
purchase put options to close out written put positions in a manner similar to
call options closing purchase transactions. In addition, the Fund may sell a put
option which it has previously purchased prior to the sale of the securities
(currencies) underlying such option. Such a sale would result in a net gain or
loss depending on whether the amount received on the sale is more or less than
the premium and other transaction costs paid on the put option which is sold.
And such gain or loss could be offset in whole or in part by a change in the
market value of the underlying security (currency). If a put option purchased by
the Fund expired without being sold or exercised, the premium would be lost.
 
    RISKS OF OPTIONS TRANSACTIONS.  During the option period, the covered call
writer has, in return for the premium on the option, given up the opportunity
for capital appreciation above the exercise price should the market price of the
underlying security (or the value of its denominated currency) increase, but has
retained the risk of loss should the price of the underlying security (or the
value of its denominated currency) decline. The secured put writer also retains
the risk of loss should the market value of the underlying security (or the
value of its denominated currency) decline below the exercise price of the
option less the premium received on the sale of the option. In both cases, the
writer has no control over the time when it may be required to fulfill its
obligation as a writer of the option. Once an option writer has received an
exercise notice, it cannot effect a closing purchase transaction in order to
terminate its obligation under the option and must deliver or receive the
underlying securities at the exercise price.
 
    Prior to exercise or expiration, an option position can only be terminated
by entering into a closing purchase or sale transaction. If a covered call
option writer is unable to effect a closing purchase transaction or to purchase
an offsetting OTC option, it cannot sell the underlying security until the
option expires or the option is exercised. Accordingly, a covered call option
writer may not be able to sell an underlying security at a time when it might
otherwise be advantageous to do so. A secured put option writer who is unable to
effect a closing purchase transaction or to purchase an offsetting OTC option
would continue to bear the risk of decline in the market price of the underlying
security until the option expires or is exercised. In addition, a secured put
writer would be unable to utilize the amount held in cash or U.S. Government or
other liquid portfolio securities as security for the put option for other
investment purposes until the exercise or expiration of the option.
 
    As discussed in the Prospectus, the Fund's ability to close out its position
as a writer of an option is dependent upon the existence of a liquid secondary
market on Option Exchanges. There is no assurance that such a market will exist,
particularly in the case of OTC options, as such options will generally only be
closed out by entering into a closing purchase transaction with the purchasing
dealer. However, the Fund may be able to purchase an offsetting option which
does not close out its position as a writer but constitutes an asset of equal
value to the obligation under the option written. If the Fund is not able to
either enter into a closing purchase transaction or purchase an offsetting
position, it will be required to maintain the securities subject to the call, or
the collateral underlying the put, even though it might not be advantageous to
do so, until a closing transaction can be entered into (or the option is
exercised or expires).
 
    Among the possible reasons for the absence of a liquid secondary market on
an Exchange are: (i) insufficient trading interest in certain options; (ii)
restrictions on transactions imposed by an Exchange; (iii) trading halts,
suspensions or other restrictions imposed with respect to particular classes or
series of options or underlying securities; (iv) interruption of the normal
operations on an Exchange; (v) inadequacy of the facilities of an Exchange or
the Options Clearing Corporation ("OCC") to handle current trading volume; or
(vi) a decision by one or more Exchanges to discontinue the trading of options
 
                                       20
<PAGE>
(or a particular class or series of options), in which event the secondary
market on that Exchange (or in that class or series of options) would cease to
exist, although outstanding options on that Exchange that had been issued by the
OCC as a result of trades on that Exchange would generally continue to be
excercisable in accordance with their terms.
 
    In the event of the bankruptcy of a broker through which the Fund engages in
transactions in options, the Fund could experience delays and/or losses in
liquidating open positions purchased or sold through the broker and/or incur a
loss of all or part of its margin deposits with the broker. Similarly, in the
event of the bankruptcy of the writer of an OTC option purchased by the Fund,
the Fund could experience a loss of all or part of the value of the option.
Transactions are entered into by the Fund only with brokers or financial
institutions deemed creditworthy by the Investment Manager.
 
    Each of the Exchanges has established limitations governing the maximum
number of call or put options on the same underlying security or futures
contract (whether or not covered) which may be written by a single investor,
whether acting alone or in concert with others (regardless of whether such
options are written on the same or different Exchanges or are held or written on
one or more accounts or through one or more brokers). An Exchange may order the
liquidation of positions found to be in violation of these limits and it may
impose other sanctions or restrictions. These position limits may restrict the
number of listed options which the Fund may write.
 
    The hours of trading for options may not conform to the hours during which
the underlying securities are traded. To the extent that the option markets
close before the markets for the underlying securities, significant price and
rate movements can take place in the underlying markets that cannot be reflected
in the option markets.
 
    The extent to which the Fund may enter into transactions involving options
may be limited by the Internal Revenue Code's requirements for qualification as
a regulated investment company and the Fund's intention to qualify as such (see
"Dividends, Distributions and Taxes" in the Prospectus).
 
    FUTURES CONTRACTS.  As stated in the Prospectus, the Fund may purchase and
sell interest rate, currency, and index futures contracts ("futures contracts"),
that are traded on U.S. and foreign commodity exchanges, on such underlying
securities as U.S. Treasury bonds, notes and bills and/or any foreign government
fixed-income security ("interest rate" futures), on various currencies
("currency futures") and on such indexes of U.S. and foreign fixed-income
securities as may exist or come into being, such as the Moody's Investment-Grade
Corporate Bond Index ("index" futures).
 
    The Fund will purchase or sell interest rate futures contracts and bond
index futures contracts for the purpose of hedging its fixed-income portfolio
(or anticipated portfolio) against changes in prevailing interest rates and to
alter the Fund's asset allocation in fixed-income securities. If the Investment
Manager anticipates that interest rates may rise and, concomitantly, the price
of fixed-income securities fall, or wishes to decrease the Fund's asset
allocation in fixed-income securities, the Fund may sell an interest rate
futures contract or a bond index futures contract. If declining interest rates
are anticipated or if the Investment Manager wishes to increase the Fund's asset
allocation of fixed-income securities, the Fund may purchase an interest rate
futures contract to protect against a potential increase in the price of U.S.
Government securities the Fund intends to purchase. Subsequently, appropriate
fixed-income securities may be purchased by the Fund in an orderly fashion; as
securities are purchased, corresponding futures positions would be terminated by
offsetting sales of contracts.
 
    Although most interest rate futures contracts call for actual delivery or
acceptance of securities, the contracts usually are closed out before the
settlement date without the making or taking of delivery. A futures contract
sale is closed out by effecting a futures contract purchase for the same
aggregate amount of the specific type of security (currency) and the same
delivery date. If the sale price exceeds the offsetting purchase price, the
seller would be paid the difference and would realize a gain. If the offsetting
purchase price exceeds the sale price, the seller would pay the difference and
would realize a loss. Similarly, a futures contract purchase is closed out by
effecting a futures contract sale for the same aggregate amount of the specific
type of security (currency) and the same delivery date. If the offsetting
 
                                       21
<PAGE>
sale price exceeds the purchase price, the purchaser would realize a gain,
whereas if the purchase price exceeds the offsetting sale price, the purchaser
would realize a loss. There is no assurance that the Fund will be able to enter
into a closing transaction.
 
    INTEREST RATE FUTURES CONTRACTS.  When the Fund enters into an interest rate
futures contract, it is initially required to deposit with the Fund's Custodian,
in a segregated account in the name of the broker performing the transaction, an
"initial margin" of cash or U.S. Government securities or other liquid portfolio
securities equal to approximately 3% of the contract amount. Initial margin
requirements are established by the Exchanges on which futures contracts trade
and may, from time to time, change. In addition, brokers may establish margin
deposit requirements in excess of those required by the Exchanges.
 
    Initial margin in futures transactions is different from margin in
securities transactions in that initial margin does not involve the borrowing of
funds by a brokers' client but is, rather, a good faith deposit on the futures
contract which will be returned to the Fund upon the proper termination of the
futures contract. The margin deposits made are marked to market daily and the
Fund may be required to make subsequent deposits of cash or U.S. Government
securities or other liquid portfolio securities called "variation margin," with
the Fund's futures contract clearing broker, which are reflective of price
fluctuations in the futures contract. Currently, interest rate 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, GNMA Certificates and
Bank Certificates of Deposit.
 
    CURRENCY FUTURES.  Generally, foreign currency futures provide for the
delivery of a specified amount of a given currency, on the exercise date, for a
set exercise price denominated in U.S. dollars or other currency. Foreign
currency futures contracts would be entered into for the same reason and under
the same circumstances as forward foreign currency exchange contracts. The
Investment Manager will assess such factors as cost spreads, liquidity and
transaction costs in determining whether to utilize futures contracts or forward
contracts its in foreign currency transactions and hedging strategy. Currently,
currency futures exist for, among other foreign currencies, the Japanese yen,
West German marks, Canadian dollars, British pound, Swiss franc and European
currency unit.
 
    Purchasers and sellers of foreign currency futures contracts are subject to
the same risks that apply to the buying and selling of futures generally. In
addition, there are risks associated with foreign currency futures contracts and
their use as a hedging device similar to those associated with options on
foreign currencies described above. Further, settlement of a foreign currency
futures contract must occur within the country issuing the underlying currency.
Thus, the Fund must accept or make delivery of the underlying foreign currency
in accordance with any U.S. or foreign restrictions or regulation regarding the
maintenance of foreign banking arrangements by U.S. residents and may be
required to pay any fees, taxes or charges associated with such delivery which
are assessed in the issuing country.
 
    Options on foreign currency futures contracts may involve certain additional
risks. Trading options on foreign currency futures contracts is relatively new.
The ability to establish and close out positions on such options is subject to
the maintenance of a liquid secondary market. To reduce this risk, the Fund will
not purchase or write options on foreign currency futures contracts unless and
until, in the Investment Manager's opinion, the market for such options has
developed sufficiently that the risks in connection with such options are not
greater than the risks in connection with transactions in the underlying foreign
currency futures contracts.
 
    INDEX FUTURES CONTRACTS.  As discussed in the Prospectus, the Fund may
invest in index futures contracts. An index futures contract sale creates an
obligation by the Fund, as seller, to deliver cash at a specified future time.
An index futures contract purchase would create an obligation by the Fund, as
purchaser, to take delivery of cash at a specified future time. Futures
contracts on indexes do not require the physical delivery of securities, but
provide for a final cash settlement on the expiration date which reflects
accumulated profits and losses credited or debited to each party's account.
 
                                       22
<PAGE>
    The Fund is required to maintain margin deposits with brokerage firms
through which it effects index futures contracts in a manner similar to that
described above for interest rate futures contracts. Currently, the initial
margin requirements range from 3% to 10% of the contract amount for index
futures. 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.
 
    At any time prior to expiration of the futures contract, the Fund may elect
to close the position by taking an opposite position which will operate to
terminate the Fund's position in the futures contract. A final determination of
variation margin is then made, additional cash is required to be paid by or
released to the Fund and the Fund realizes a loss or gain.
 
    OPTIONS ON FUTURES CONTRACTS.  The Fund may purchase and write call and put
options on futures contracts which are traded on an Exchange and enter into
closing transactions with respect to such options to terminate an existing
position. An option on a futures contract gives the purchaser the right (in
return for the premium paid), to assume a position in a futures contract (a long
position if the option is a call and a short position if the option is a put) at
a specified exercise price at any time during the term of the option. Upon
exercise of the option, the delivery of the futures position by the writer of
the option to the holder of the option is accompanied by delivery of the
accumulated balance in the writer's futures margin account, which represents the
amount by which the market price of the futures contract at the time of exercise
exceeds, in the case of a call, or is less than, in the case of a put, the
exercise price of the option on the futures contract.
 
    The Fund will purchase and write options on futures contracts for identical
purposes to those set forth above for the purchase of a futures contract
(purchase of a call option or sale of a put option) and the sale of a futures
contract (purchase of a put option or sale of a call option), or to close out a
long or short position in futures contracts. If, for example, the Investment
Manager wished to protect against an increase in interest rates and the
resulting negative impact on the value of a portion of its fixed-income
portfolio, it might write a call option on an interest rate futures contract,
the underlying security of which correlates with the portion of the portfolio
the Investment Manager seeks to hedge. Any premiums received in the writing of
options on futures contracts may, of course, augment the total return of the
Fund and thereby provide a further hedge against losses resulting from price
declines in portions of the Fund's portfolio.
 
    The writer of an option on a futures contract is required to deposit initial
and variation margin pursuant to requirements similar to those applicable to
futures contracts. Premiums received from the writing of an option on a futures
contract are included in initial margin deposits.
 
    LIMITATIONS ON FUTURES CONTRACTS AND OPTIONS ON FUTURES.  The Fund may not
enter into futures contracts or purchase related options thereon if, immediately
thereafter, the amount committed to margin plus the amount paid for premiums for
unexpired options on futures contracts exceeds 5% of the value of the Fund's
total assets, after taking into account unrealized gains and unrealized losses
on such contracts it has entered into, provided, however, that in the case of an
option that is in-the-money (the exercise price of the call (put) option is less
(more) than the market price of the underlying security) at the time of
purchase, the in-the-money amount may be excluded in calculating the 5%.
However, there is no overall limitation on the percentage of the Fund's assets
which may be subject to a hedge position. In addition, in accordance with the
regulations of the Commodity Futures Trading Commission ("CFTC") under which the
Fund is exempted from registration as a commodity pool operator, the Fund may
only enter into futures contracts and options on futures contracts transactions
for purposes of hedging a part or all of its portfolio. If the CFTC changes its
regulations so that the Fund would be permitted to write options on futures
contracts for purposes other than hedging the Fund's investments without CFTC
registration, the Fund may engage in such transactions for those purposes.
Except as described above, there are no other limitations on the use of futures
and options thereon by the Fund.
 
    RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS.  As stated
in the Prospectus, the Fund may sell a futures contract to protect against the
decline in the value of securities (or the currency in
 
                                       23
<PAGE>
which they are denominated) held by the Fund. However, it is possible that the
futures market may advance and the value of securities (or the currency in which
they are denominated) held in the portfolio of the Fund may decline. If this
occurred, the Fund would lose money on the futures contract and also experience
a decline in value of its portfolio securities. However, while this could occur
for a very brief period or to a very small degree, over time the value of a
diversified portfolio will tend to move in the same direction as the futures
contracts.
 
    If the Fund purchases a futures contract to hedge against the increase in
value of securities it intends to buy (or the currency in which they are
denominated), and the value of such securities (currencies) decreases, then the
Fund may determine not to invest in the securities as planned and will realize a
loss on the futures contract that is not offset by a reduction in the price of
the securities.
 
    If the Fund has sold a call option in a futures contract, it will cover this
position by holding, in a segregated account maintained at its Custodian, cash,
U.S. Government securities or other liquid portfolio securities equal in value
(when added to any initial or variation margin on deposit) to the market value
of the securities (currencies) underlying the futures contract or the exercise
price of the option. Such a position may also be covered by owning the
securities (currencies) underlying the futures contract, or by holding a call
option permitting the Fund to purchase the same contract at a price no higher
than the price at which the short position was established.
 
    In addition, if the Fund holds a long position in a futures contract or has
sold a put option on a futures contract, it will hold cash, U.S. Government
securities or other liquid portfolio securities equal to the purchase price of
the contract or the exercise price of the put option (less the amount of initial
or variation margin on deposit) in a segregated account maintained for the Fund
by its Custodian. Alternatively, the Fund could cover its long position by
purchasing a put option on the same futures contract with an exercise price as
high or higher than the price of the contract held by the Fund.
 
    Exchanges limit the amount by which the price of a futures contract may move
on any day. If the price moves equal the daily limit on successive days, then it
may prove impossible to liquidate a futures position until the daily limit moves
have ceased. In the event of adverse price movements, the Fund would continue to
be required to make daily cash payments of variation margin on open futures
positions. In such situations, if the Fund has insufficient cash, it may have to
sell portfolio securities to meet daily variation margin requirements at a time
when it may be disadvantageous to do so. In addition, the Fund may be required
to take or make delivery of the instruments underlying interest rate futures
contracts it holds at a time when it is disadvantageous to do so. The inability
to close out options and futures positions could also have an adverse impact on
the Fund's ability to effectively hedge its portfolio.
 
    Futures contracts and options thereon which are purchased or sold on foreign
commodities exchanges may have greater price volatility than their U.S.
counterparts. Furthermore, foreign commodities exchanges may be less regulated
and under less governmental scrutiny than U.S. exchanges. Brokerage commissions,
clearing costs and other transaction costs may be higher on foreign exchanges.
Greater margin requirements may limit the Fund's ability to enter into certain
commodity transactions on foreign exchanges. Moreover, differences in clearance
and delivery requirements on foreign exchanges may occasion delays in the
settlement of the Fund's transactions effected on foreign exchanges.
 
    In the event of the bankruptcy of a broker through which the Fund engages in
transactions in futures or options thereon, the Fund could experience delays
and/or losses in liquidating open positions purchased or sold through the broker
and/or incur a loss of all or part of its margin deposits with the broker.
Similarly, in the event of the bankruptcy of the writer of an OTC option
purchased by the Fund, the Fund could experience a loss of all or part of the
value of the option. Transactions are entered into by the Fund only with brokers
or financial institutions deemed creditworthy by the Investment Manager.
 
    While the futures contracts and options transactions to be engaged in by the
Fund for the purpose of hedging the Fund's portfolio securities are not
speculative in nature, there are risks inherent in the use
 
                                       24
<PAGE>
of such instruments. One such risk which may arise in employing futures
contracts to protect against the price volatility of portfolio securities (and
the currencies in which they are denominated) is that the prices of securities
and indexes subject to futures contracts (and thereby the futures contract
prices) may correlate imperfectly with the behavior of the cash prices of the
Fund's portfolio securities (and the currencies in which they are denominated).
Another such risk is that prices of interest rate futures contracts may not move
in tandem with the changes in prevailing interest rates against which the Fund
seeks a hedge. A correlation may also 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.
 
    As stated in the Prospectus, there may exist an imperfect correlation
between the price movements of futures contracts purchased by the Fund and the
movements in the prices of the securities (currencies) which are the subject of
the hedge. If participants in the futures market elect to close out their
contracts through offsetting transactions rather than meet margin deposit
requirements, distortions in the normal relationship between the debt securities
or currency markets and futures markets could result. Price distortions could
also result if investors in futures contracts opt to make or take delivery of
underlying securities rather than engage in closing transactions due to the
resultant reduction in the liquidity of the futures market. In addition, due to
the fact that, from the point of view of speculators, the deposit requirements
in the futures markets are less onerous than margin requirements in the cash
market, increased participation by speculators in the futures market could cause
temporary price distortions. Due to the possibility of price distortions in the
futures market and because of the imperfect correlation between movements in the
prices of securities and movements in the prices of futures contracts, a correct
forecast of interest rate trends by the Investment Manager may still not result
in a successful hedging transaction.
 
    As stated in the Prospectus, there is no assurance that a liquid secondary
market will exist for futures contracts and related options in which the Fund
may invest. In the event a liquid market does not exist, it may not be possible
to close out a futures position, and in the event of adverse price movements,
the Fund would continue to be required to make daily cash payments of variation
margin. In addition, limitations imposed by an exchange or board of trade on
which futures contracts are traded may compel or prevent the Fund from closing
out a contract which may result in reduced gain or increased loss to the Fund.
The absence of a liquid market in futures contracts might cause the Fund to make
or take delivery of the underlying securities (currencies) at a time when it may
be disadvantageous to do so.
 
    The extent to which the Fund may enter into transactions involving futures
contracts and options thereon may be limited by the Internal Revenue Code's
requirements for qualification as a regulated investment company and the Fund's
intention to qualify as such (see "Dividends, Distributions and Taxes" in the
Prospectus).
 
    Compared to the purchase or sale of futures contracts, the purchase of call
or put options on futures contracts involves less potential risk to the Fund
because the maximum amount at risk is the premium paid for the options (plus
transaction costs). However, there may be circumstances when the purchase of a
call or put option on a futures contract would result in a loss to the Fund
notwithstanding that the purchase or sale of a futures contract would not result
in a loss, as in the instance where there is no movement in the prices of the
futures contract or underlying securities (currencies).
 
REPURCHASE AGREEMENTS
 
    When cash may be available for only a few days, it may be invested by the
Fund in repurchase agreements until such time as it may otherwise be invested or
used for payments of obligations of the Fund. A repurchase agreement may be
viewed as a type of secured lending by the Fund which typically involves the
acquisition by the Fund of government securities from a selling financial
institution such as a bank, savings and loan association or broker-dealer. The
agreement provides that the Fund will sell back to the institution, and that the
institution will repurchase, the underlying security ("collateral") at a
specified price and at a fixed time in the future, usually not more than seven
days from the date of
 
                                       25
<PAGE>
   
purchase. The collateral will be maintained in a segregated account and will be
marked-to-market daily to determine that the full value of the collateral, as
specified in the agreement, does not decrease below the repurchase price plus
accrued interest. If such decrease occurs, additional collateral will be
requested from the counterparty and will be added to the account to maintain
full collateralization. In the event the original seller defaults on its
obligations to repurchase, as a result of its bankruptcy or otherwise, the Fund
will seek to sell the collateral, which action could involve costs or delays. In
such case, the Fund's ability to dispose of the collateral to recover its
investment may be restricted or delayed.
    
 
    The Fund will accrue interest from the institution until the time when the
repurchase is to occur. Although such date is deemed by the Fund to be the
maturity date of a repurchase agreement, the maturities of securities subject to
repurchase agreements are not subject to any limits and may exceed one year.
 
    While repurchase agreements involve certain risks not associated with direct
investments in debt securities, the Fund follows procedures designed to minimize
such risks. Repurchase agreements will be transacted only with large,
well-capitalized and well-established financial institutions whose financial
condition will be continuously monitored by the Investment Manager subject to
procedures established by the Trustees. The procedures also require that the
collateral underlying the agreement be specified. The Fund does not presently
intend to enter into repurchase agreements so that more than 5% of the Fund's
net assets are subject to such agreements.
 
REVERSE REPURCHASE AGREEMENTS
 
    The Fund may also use reverse repurchase agreements for purposes of meeting
redemptions or as part of its investment strategy. Reverse repurchase agreements
involve sales by the Fund of portfolio assets concurrently with an agreement by
the Fund to repurchase the same assets at a later date at a fixed price.
Generally, the effect of such a transaction is that the Fund can recover all or
most of the cash invested in the portfolio securities involved during the term
of the reverse repurchase agreement, while it will be able to keep the interest
income associated with those portfolio securities. Such transactions are only
advantageous if the interest cost to the Fund of the reverse repurchase
transaction is less than the cost of obtaining the cash otherwise. Opportunities
to achieve this advantage may not always be available, and the Fund intends to
use the reverse repurchase technique only when it will be to its advantage to do
so. The Fund will establish a segregated account with its custodian bank in
which it will maintain cash or cash equivalents or other liquid portfolio
securities (i.e. U.S. Government securities) equal in value to its obligations
in respect of reverse repurchase agreements. Reverse repurchase agreements are
considered borrowings by the Fund and, in accordance with legal requirements,
the Fund will maintain an asset coverage (including the proceeds) of at least
300% with respect to all reverse repurchase agreements. Reverse repurchase
agreements may not exceed 10% of the Fund's total assets.
 
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,
 
                                       26
<PAGE>
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. The Investment Manager and the Trustees do not believe that the
Fund's net asset value or income will be adversely affected by its purchase of
securities on such basis.
 
WHEN, AS AND IF ISSUED SECURITIES
 
    As discussed in the Prospectus, the Fund may purchase securities on a "when,
as and if issued" basis under which the issuance of the security depends upon
the occurrence of a subsequent event, such as approval of a merger, corporate
reorganization, leveraged buyout or debt restructuring. The commitment for the
purchase of any such security will not be recognized in the portfolio of the
Fund until the Investment Manager determines that issuance of the security is
probable. At such time, the Fund will record the transaction and, in determining
its net asset value, will reflect the value of the security daily. At such time,
the Fund will also establish a segregated account with its custodian bank in
which it will continuously maintain cash or U.S. Government securities or other
liquid portfolio securities equal in value to recognized commitments for such
securities. Settlement of the trade will occur within five business days of the
occurrence of the subsequent event. The value of the Fund's commitments to
purchase the securities of any one issuer, together with the value of all
securities of such issuer owned by the Fund, may not exceed 5% of the value of
the Fund's total assets at the time the initial commitment to purchase such
securities is made (see "Investment Restrictions"). Subject to the foregoing
restrictions, 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, as and if issued" basis may increase the volatility of
its net asset value. The Investment Manager and the Trustees do not believe that
the net asset value of the Fund will be adversely affected by its purchase of
securities on such basis. The Fund may also sell securities on a "when, as and
if issued" basis provided that the issuance of the security will result
automatically from the exchange or conversion of a security owned by the Fund at
the time of the sale.
 
LENDING OF PORTFOLIO SECURITIES
 
    Consistent with applicable regulatory requirements, the Fund may lend its
portfolio securities to brokers, dealers and other financial institutions,
provided that such loans are callable at any time by the Fund (subject to notice
provisions described below), and are at all times secured by cash or appropriate
high-grade debt obligations, which are maintained in a segregated account
pursuant to applicable regulations and that are at least equal to the market
value, determined daily, of the loaned securities. The advantage of such loans
is that the Fund continues to receive the income on the loaned securities while
at the same time earning interest on the cash amounts deposited as collateral,
which will be invested in short-term obligations. The Fund will not lend 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. A loan may be terminated by the
borrower on one business days' notice, or by the Fund on two business days'
notice. If the borrower fails to deliver the loaned securities within two days
after receipt of notice, the Fund could use the collateral to replace the
securities while holding the borrower liable for any excess of replacement cost
over collateral. As with any extensions of credit, there are risks of delay in
recovery and in some cases even loss of rights in the collateral should the
borrower of the securities fail financially. However, these loans of portfolio
securities will only be made to firms deemed by the Fund's management to be
creditworthy and when the income which can be earned from such loans justifies
the attendant risks. Upon termination of the loan, the borrower is required to
return the securities to the Fund. Any gain or loss in the market price during
the loan period would inure to the Fund. The creditworthiness of firms to which
the Fund lends its portfolio securities will be monitored on an ongoing basis by
the Investment Manager pursuant to procedures adopted and reviewed, on an
ongoing basis, by the Board of Trustees of the Fund.
 
    When voting or consent rights which accompany loaned securities pass to the
borrower, the Fund will follow the policy of calling the loaned securities, to
be delivered within one day after notice, to permit
 
                                       27
<PAGE>
the exercise of such rights if the matters involved would have a material effect
on the Fund's investment in such loaned securities. The Fund will pay reasonable
finder's, administrative and custodial fees in connection with a loan of its
securities. The Fund has not to date lent any of its portfolio securities.
 
PORTFOLIO TRADING
 
    It is anticipated that the Fund's portfolio turnover rate will not exceed
300% in any one year. A 300% turnover rate would occur, for example, if 300% 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.
 
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, except as otherwise indicated. Under the Act, a
fundamental policy may not be changed without the vote of a majority of the
outstanding voting securities of the Fund, as defined in the Act. Such a
majority is defined as the lesser of (a) 67% or more of the shares present at a
meeting of shareholders, if the holders of 50% of the outstanding shares of the
Fund are present or represented by proxy or (b) more than 50% of the outstanding
shares of the Fund.
 
    The Fund may not:
 
        1.   Invest in securities of any issuer if, to the knowledge of the
           Fund, any officer or trustee of the Fund or any officer or director
    of the Investment Manager owns more than 1/2 of 1% of the outstanding
    securities of such issuer, and such officers, trustees and directors who own
    more than 1/2 of 1% own in the aggregate more than 5% of the outstanding
    securities of such issuers.
 
        2.   Purchase or sell real estate or interests therein, although the
           Fund may purchase securities of issuers which engage in real estate
    operations and securities secured by real estate or interests therein.
 
        3.   Purchase oil, gas or other mineral leases, rights or royalty
           contracts or exploration or development programs, except that the
    Fund may invest in the securities of companies which operate, invest in, or
    sponsor such programs.
 
        4.   Purchase securities of other investment companies, except in
           connection with a merger, consolidation, reorganization or
    acquisition of assets. However, the Fund may invest up to 10% of the value
    of its total assets in the securities of foreign investment companies, but
    only under circumstances where purchase of the securities of foreign
    investment companies would secure entry to national markets which are
    otherwise not open to the Fund for investment or where the security is
    issued by a foreign bank which is deemed to be an investment company under
    U.S. securities laws and/or regulations.
 
        The Fund anticipates that it will incur any indirect expenses incurred
    through investment in a foreign investment company, such as the payment of a
    management fee. Furthermore, it should be noted that foreign investment
    companies are not subject to the U.S. securities laws and may be subject to
    fewer or less stringent regulations than U.S. investment companies.
 
        5.   Borrow money (except insofar as the Fund may be deemed to have
           borrowed by entrance into a reverse repurchase agreement up to an
    amount not exceeding 10% of the Fund's total assets), 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 its total
    assets (not including the amount borrowed).
 
        6.   Pledge its assets or assign or otherwise encumber them except to
           secure borrowings effected within the limitations set forth in
    restriction (5). For the purpose of this restriction, collateral
    arrangements with respect to the writing of options and collateral
    arrangements with respect to initial or variation margin for futures are not
    deemed to be pledges of assets.
 
                                       28
<PAGE>
        7.   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 or reverse repurchase agreement; (b) purchasing
    any securities on a when-issued or delayed delivery basis; (c) purchasing or
    selling futures contracts, forward foreign exchange contracts or options;
    (d) borrowing money in accordance with restrictions described above; or (e)
    lending portfolio securities.
 
        8.   Make loans of money or securities, except: (a) by the purchase of
           publicly distributed debt obligations in which the Fund may invest
    consistent with its investment objectives and policies; (b) by investment in
    repurchase or reverse repurchase agreements; or (c) by lending its portfolio
    securities.
 
        9.   Make short sales of securities.
 
       10.   Purchase securities on margin, except for such short-term loans as
           are necessary for the clearance 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.
 
       11.   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.
 
       12.   Invest for the purpose of exercising control or management of any
           other issuer.
 
    If a percentage restriction is adhered to at the time of investment, a later
increase or decrease in percentage resulting from a change in values of
portfolio securities or amount of total or net assets will not be considered a
violation of any of the foregoing restrictions.
 
   
    Notwithstanding any other investment policy or restriction, the Fund may
seek to achieve its investment objectives by investing all or substantially all
of its assets in another investment company having substantially the same
investment objectives and policies as the Fund.
    
 
PORTFOLIO TRANSACTIONS AND BROKERAGE
- --------------------------------------------------------------------------------
 
    Subject to the general supervision of the Board of Trustees, the Investment
Manager is responsible for decisions to buy and sell securities for the Fund,
the selection of brokers and dealers to effect the transactions, and the
negotiation of brokerage commissions, if any. Purchases and sales of securities
on a stock exchange are effected through brokers who charge a commission for
their services. The Fund expects that the primary market for the securities in
which it intends to invest will generally be the over-the-counter market. In the
over-the-counter market, securities are generally traded on a "net" basis with
dealers acting as principal for their own accounts without a stated commission,
although the price of the security usually includes a profit to the dealer. The
Fund expects that securities will be purchased at times in underwritten
offerings where the price includes a fixed amount of compensation, generally
referred to as the underwriter's concession or discount. Options and futures
transactions will usually be effected through a broker and a commission will be
charged. On occasion, the Fund may also purchase certain money market
instruments directly from an issuer, in which case no commissions or discounts
are paid. During the fiscal years ended October 31, 1994, 1995 and 1996, the
Fund paid a total of $90,206, $63,973 and $53,726, respectively, in 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 may be considered, including the respective investment objectives, the
relative size of portfolio holdings of the same or comparable securities, the
availability of cash for investment, the size of investment commitments
generally held and the opinions of the persons responsible for managing the
portfolios of the Fund and other client
 
                                       29
<PAGE>
   
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 will be given to obtaining the most
favorable prices and efficient executions of transactions. Consistent with this
policy, when securities transactions are effected on a stock exchange, the
Fund's policy is to pay commissions which are considered fair and reasonable
without necessarily determining that the lowest possible commissions are paid in
all circumstances. The Fund believes that a requirement always to seek the
lowest possible commission cost could impede effective portfolio management and
preclude the Fund and the Investment Manager from obtaining a high quality of
brokerage and research services. In seeking to determine the reasonableness of
brokerage commissions paid in any transaction, the Investment Manager relies
upon its experience and knowledge regarding commissions generally charged by
various brokers and on its judgment in evaluating the brokerage and research
services received from the broker effecting the transaction. Such determinations
are necessarily subjective and imprecise, as in most cases an exact dollar value
for those services is not ascertainable.
 
    The Fund anticipates that certain of its transactions involving foreign
securities will be effected on securities exchanges. Fixed commissions on such
transactions are generally higher than negotiated commissions on domestic
transactions. There is also generally less government supervision and regulation
of foreign securities exchanges and brokers than in the United States.
 
    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 prices and executions are
obtainable from more than one broker or dealer, it may give consideration to
placing portfolio transactions with those brokers and dealers who also furnish
research and other services to the Fund or the Investment Manager. 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. During the
fiscal year ended October 31, 1996, the Fund did not direct the payment of any
brokerage commissions because of research services provided.
 
    The information and services received by the Investment Manager from brokers
and dealers may be of benefit to the Investment Manager in the management of
accounts of some of its other clients and may not in all cases benefit the Fund
directly. While the receipt of such information and services is useful in
varying degrees and would generally reduce the amount of research or services
otherwise performed by the Investment Manager and thereby reduce its expenses,
it is of indeterminable value and the management fee paid to the Investment
Manager is not reduced 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 DWR only when the price available from DWR is better than that available
from other dealers.
 
   
    Consistent with the policy described above, brokerage transactions in
securities listed on exchanges or admitted to unlisted trading privileges may be
effected through DWR and other affiliated brokers and dealers. In order for an
affiliated broker or dealer to effect any 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
    
 
                                       30
<PAGE>
   
broker in a commensurate arm's-length transaction. Furthermore, the Trustees of
the Fund, including a majority of the Trustees who are not "interested" persons
of the Fund, as defined in the Act, 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. During
the fiscal years ended October 31, 1994, 1995 and 1996, the Fund did not effect
any securities transactions with or through an affiliated broker or dealer.
    
 
THE DISTRIBUTOR
- --------------------------------------------------------------------------------
 
   
    As discussed in the Prospectus, shares of the Fund are distributed by Dean
Witter Distributors Inc. (the "Distributor"). 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 broker-dealers. The Distributor, a
Delaware corporation, is a wholly-owned subsidiary of MSDWD. The Trustees of the
Fund, 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 as exclusive
distributor of the Fund's shares and providing for the Distributor to bear
distribution expenses not borne by the Fund. The current Distribution Agreement
is substantively identical to the Fund's previous distribution agreement in all
material respects, except for the dates of effectiveness. 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 incurred 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 and state securities laws and pays filing fees in
accordance with state securities laws. The Fund and the Distributor have agreed
to indemnify each other against certain liabilities, including liabilities under
the Securities Act 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 any 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 0.85% of the average daily net assets of Class A and
Class C, respectively, and, with respect to Class B, 0.85% 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
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 approximately $637,000, $338,000 and $109,685 in contingent deferred
sales charges for the fiscal years ended October 31, 1994, 1995 and 1996,
respectively.
    
 
                                       31
<PAGE>
   
    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 January 31, 1989, by
DWR as the then sole shareholder of the Fund on February 1, 1989 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 June 26, 1990.
 
   
    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 by the Distributor under the Plan and
the purpose for which such expenditures were made. The Fund accrued amounts
payable to the Distributor under the Plan, during the fiscal year ended October
31, 1996, of $1,058,190. This amount is equal to 0.85% 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. This amount represents amounts paid by
Class B only; there were no Class A or Class C shares outstanding on such date.
    
 
   
    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) or net asset value purchases by 401(k) plans or
    
 
                                       32
<PAGE>
   
other employer-sponsored plans qualified under Section 401(a) of the Internal
Revenue Code for which Dean Witter Trust Company ("DWTC") or Dean Witter Trust
FSB ("DWTFSB") serves as Trustee or the 401(k) Support Services Group of DWR
serves as recordkeeper, 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 (except as
provided in the following sentence) 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. In the case of
retirement plans qualified under Section 401(k) of the Internal Revenue Code and
other employer-sponsored plans qualified under Section 401(a) of the Internal
Revenue Code for which DWTC or DWTFSB serves as Trustee or the 401(k) Support
Services Group of DWR serves as recordkeeper, and which plans are opened on or
after July 28, 1997, DWR compensates its account executives by paying them, from
its own funds, a gross sales credit of 3.0% of the amount sold.
    
 
   
    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 0.85% 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 paid 100% of the $1,058,190 accrued under the Plan for the fiscal
year ended October 31, 1996 to the Distributor. The Distributor and DWR estimate
that they have spent, pursuant to the Plan, $34,958,755 on behalf of the Fund
since the inception of the Fund. It is estimated that this amount was spent in
approximately the following ways: (i) 6.29% ($2,198,826) -- advertising and
promotional expenses; (ii) 0.55% ($191,095) -- printing of prospectuses for
distribution to other than current
share-
 
                                       33
<PAGE>
   
holders; and (iii) 93.16% ($32,568,834) -- other expenses, including the gross
sales credit and the carrying charge, of which 14.21% ($4,628,835) represents
carrying charges, 33.35% ($10,863,072) represents commission credits to DWR
branch offices for payments of commissions to account executives; and 52.44%
($17,076,927) represents overhead and other branch office distribution-related
expenses. These amounts represent amounts paid by Class B only; there were no
Class A or Class C shares outstanding on such date.
    
 
   
    The Fund is authorized to reimburse expenses incurred or to be incurred in
promoting the distribution of the Fund's Class A and Class C shares and in
servicing shareholder accounts. Reimbursement will be made through payments at
the end of each month. The amount of each monthly payment may in no event exceed
an amount equal to a payment at the annual rate of 0.25%, in the case of Class
A, and 0.85%, 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.
    
 
   
    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 $8,308,200 as of October 31, 1996. 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.
    
 
   
    Under its terms, the Plan had an initial term ending April 30, 1989, and
will remain in effect from year to year thereafter, provided such continuance is
approved annually by a vote of the Independent 12b-1 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 continuation
    
 
                                       34
<PAGE>
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 stated in the Prospectus, short-term securities with remaining maturities
of sixty days or less at the time of purchase are valued at amortized cost,
unless the Trustees determine such does not reflect the securities' market
value, in which case these securities will be valued at their fair value as
determined by the Trustees. Other short-term debt securities will be valued on a
mark-to-market basis until such time as they reach 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 does not reflect the securities'
market value, in which case these securities will be valued at their fair value
as determined by the Trustees. Listed options are valued at the latest sale
price on the exchange on which they are listed unless no sales of such options
have taken place that day, in which case they will be valued at the mean between
their latest bid and asked prices. Unlisted options are valued at the mean
between their latest bid and asked prices. Futures are valued at the latest sale
price on the commodities exchange on which they trade unless the Trustees
determine such price does not reflect their market value. All other securities
and other assets are valued at their fair value as determined in good faith
under procedures established by and under the supervision of the Trustees.
 
   
    The net asset value per share for each Class of shares of the Fund is
determined once daily as of 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.
    
 
                                       35
<PAGE>
   
    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 Dean Witter Trust Company (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 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.

<PAGE>
   
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 (or, in the case of
shares held by certain employer-sponsored benefit plans, three 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 (or, in the case of shares held by certain
employer-sponsored benefit plans, three 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 (three) 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 (or, in the case of shares held by certain employer-sponsored
benefit plans, three 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 (three) 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 (or, in the case of shares held by certain
employer-sponsored benefit plans, three 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.
    
 
   
    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
most Class B shares of the Fund:

shares of the Fund held by 401(k) plans or other employer-sponsored plans
qualified under Section 401(a) of the Internal Revenue Code for which DWTC or

    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 or three-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 (or,
in the case of shares held by certain employer-sponsored benefit plans, three
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 confirmation of
the transaction from the Fund or from DWR or other selected broker-dealer.
    
 
   
    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 record date. 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 record date of the dividend or distribution. In the case of recently
purchased shares for which registration instructions have not been received on
the record date, cash payments will be made to DWR or other selected
broker-dealer, and will be forwarded to the shareholder, upon the receipt of
proper instructions.
    
 
   
    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
    
 
                                       38
<PAGE>
   
open-end Dean Witter Fund other than Dean Witter World Wide Income Trust or in
another Class of Dean Witter World Wide Income Trust. 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 selected Dean Witter
Fund as of the close of business on the payment date of the dividend or
distribution 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
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. 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.  As discussed in
the Prospectus, any shareholder who receives a cash payment representing a
dividend or distribution may invest such dividend or distribution in shares of
the applicable Class at net asset value, without the imposition of a CDSC upon
redemption, by returning the check or the proceeds to the Transfer Agent within
30 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.
    
 
   
    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 amount, not less
than $25, or in any whole percentage of the account balance, on an annualized
basis. Any applicable CDSC will be imposed on shares redeemed under the
Withdrawal Plan (see "Purchase of Fund Shares"). Therefore, any shareholder
participating in the Withdrawal Plan will have sufficient shares redeemed from
his or her account so that the proceeds (net of any applicable CDSC) to the
shareholder will be the designated monthly or quarterly amount.
    
 
    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 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").
    
 
                                       39
<PAGE>
    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 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.
 
   
    DIRECT INVESTMENTS THROUGH TRANSFER AGENT.  As discussed in the Prospectus,
shareholders may make additional investments in any Class of shares of the Fund
for which they qualify at any time by sending a check in any amount, not less
than $100, payable to Dean Witter World Wide Income Trust, 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.
    
 
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., Dean Witter High
Income Securities and Dean Witter National Municipal Trust, which are Dean
Witter Funds offered with a CDSC ("CDSC Funds"). 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.
    
 
    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 captions "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 any CDSC Fund 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
    
 
                                       40
<PAGE>
   
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 an 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 a CDSC Fund. However, in the case of shares exchanged for
shares of 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 or a money market fund
pursuant to this exchange privilege may exchange those shares back into a Dean
Witter Multi-Class Fund or a CDSC Fund 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 a CDSC Fund 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 CDSC
Fund, a Dean Witter Multi-Class Fund or in a CDSC Fund. 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 a
CDSC Fund are exchanged for shares of a Dean Witter Multi-Class Fund, shares of
a CDSC Fund, 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 upon the CDSC schedule applicable to the
shares) prior to the exchange, (ii) originally acquired through reinvestment of
dividends or distributions of the Fund or another Dean Witter Fund 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 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. The
Transfer Agent shall be liable for
 
                                       41
<PAGE>
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 New York
Municipal Money Market Trust and Dean Witter California Tax-Free Daily Income
Trust, although those funds may, at 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, at 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 for 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 an
Exchange Fund 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(s), policies and restrictions.
 
    For further information regarding the Exchange Privilege, shareholders
should contact their DWR or other selected broker-dealer account executive or
the Transfer Agent.
 
REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 
   
    REDEMPTION.  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, NJ 07303 is required. If certificates are held by
the shareholder, the shares may be redeemed by surrendering the certificates
with a written request for redemption. 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 accom-
    
 
                                       42
<PAGE>
panied 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 new 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. 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. 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). Shareholders maintaining margin
accounts with DWR or another selected broker-dealer are referred to their
account executive regarding restrictions on redemption of shares of the Fund
pledged in the margin account.
    
 
   
    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 the CDSC or free of such charge (and with regard to the length
of time shares subject to the charge have been held), any transfer involving
less than all of the shares in an account will be made on a pro-rata basis (that
is, by transferring shares in the same proportion that the transferred shares
bear to the total shares in the account immediately prior to the transfer). The
transferred shares will continue to be subject to any applicable CDSC as if they
had not been so transferred.
    
 
                                       43
<PAGE>
   
    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 date of
redemption or repurchase reinstate any portion of 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 such
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 discussed in the Prospectus, the Fund will determine either to distribute
or to retain all or part of any net long-term capital gains in any year for
reinvestment. If any such gains are retained, the Fund will pay federal income
tax thereon, and, if the Fund makes an election, the shareholders would include
such undistributed gains in their income and shareholders will be able to claim
their share of the tax paid by the Fund as a credit against their individual
federal income tax.
 
    In computing net investment income, the Fund will not amortize premiums or
accrue discounts on fixed-income securities in the portfolio, except those
original issue discounts or acquisition discounts for which accrual is required
for federal income tax purposes. Additionally, with respect to market discounts
on bonds, a portion of any capital gain realized upon disposition may be
characterized as taxable ordinary income. Realized gains and losses on security
transactions are determined on the identified cost method.
 
    Gains or losses on 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. Gains or losses on the sale of securities held for twelve months
or less will be short-term gains or losses.
 
    The Fund has qualified and intends to continue to qualify as a regulated
investment company under Subchapter M of the Internal Revenue Code of 1986 (the
"Code"). If so qualified, the Fund will not be subject to federal income tax on
its net investment income and capital gains, if any, realized during any fiscal
year in which it distributes such income and capital gains to its shareholders.
 
    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 company by the exact amount of the dividend or
capital gains distribution. Furthermore, capital gains distributions and
dividends are subject to federal income taxes. If the net asset value of the
shares should be reduced below a shareholder's cost as a result of the payment
of dividends or the distribution of realized net long-term capital gains, such
payment or distribution would be in part a return of the shareholder's
investment to the extent of such reduction below the shareholder's cost, but
nonetheless would be fully taxable. Therefore, an investor should consider the
tax implications of purchasing Fund shares immediately prior to a distribution
record date.
 
    Dividends, interest and capital gains received by the Fund may give rise to
withholding and other taxes imposed by foreign countries. Tax conventions
between certain countries and the United States may reduce or eliminate such
taxes. Investors may be entitled to claim United States foreign tax credits with
respect to such taxes, subject to certain provisions and limitations contained
in the Code. If more than 50% of the Fund's total assets at the close of its
fiscal year consist of securities of foreign corporations, the Fund would be
eligible and would determine whether or not to file an election with the
Internal Revenue Service pursuant to which shareholders of the Fund will be
required to include their respective pro rata portions of such withholding taxes
in their United States income tax returns as gross income, treat such respective
pro rata portions as taxes paid by them, and deduct such respective pro
 
                                       44
<PAGE>
rata portions in computing their taxable incomes or, alternatively, use them as
foreign tax credits against their United States income taxes. If the Fund does
elect to file the election with the Internal Revenue Service, the Fund will
report annually to its shareholders the amount per share of such withholding.
 
    SPECIAL RULES FOR CERTAIN FOREIGN CURRENCY TRANSACTIONS.  In general, gains
from foreign currencies and from foreign currency options, foreign currency
futures and forward foreign exchange contracts relating to investments in stock,
securities or foreign currencies will be qualifying income for purposes of
determining whether the Fund qualifies as a regulated investment company. It is
currently unclear, however, who will be treated as the issuer of a foreign
currency instrument or how foreign currency options, futures, or forward foreign
currency contracts will be valued for purposes of the regulated investment
company diversification requirements applicable to the Fund. The Fund may
request a private letter ruling from the Internal Revenue Service on some or all
of these issues.
 
    Under Code Section 988, special rules are provided for certain transactions
in a foreign currency other than the taxpayer's functional currency (I.E.,
unless certain special rules apply, currencies other than the U.S. dollar). In
general, foreign currency gains or losses from forward contracts, from futures
contracts that are not "regulated futures contracts," and from unlisted options
will be treated as ordinary income or loss under Code Section 988. Also, certain
foreign exchange gains derived with respect to foreign fixed-income securities
are also subject to Section 988 treatment. In general, however, Code Section 988
gains or losses will increase or decrease the amount of the Fund's investment
company taxable income available to be distributed to shareholders as ordinary
income, rather than increasing or decreasing the amount of the Fund's net
capital gain. Additionally, if Code Section 988 losses exceed other investment
company taxable income during a taxable year, the Fund would not be able to make
any ordinary dividend distributions.
 
    Shareholders are urged to consult their attorneys or tax advisers regarding
specific questions as to federal, state or local taxes.
 
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
subtracted from the result and the difference is multiplied by 2 to arrive at
the annualized yield. For the 30-day period ended October 31, 1996, the Fund's
yield, calculated pursuant to the formula described above, was 4.85%. This yield
is for Class B only; there were no other Classes of shares outstanding on such
date.
    
 
   
    The Fund's "average annual total return" represents an annualization of the
Fund's total return over a particular period and is computed by finding the
annual percentage rate which will result in the ending redeemable value of a
hypothetical $1,000 investment made at the beginning of a one, five or ten year
period, or for the period from the date of commencement of 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 years in the period) and subtracting 1 from
the result. The average annual returns of the Fund for the fiscal year ended
October 31, 1996, for the five years ended October 31, 1996 and for the period
March 30, 1989 (commencement of the Fund's operations) through October 31, 1996
were 7.60%, 7.10% and 7.08%, respectively. These returns are for Class B only;
there were no other Classes of shares outstanding on such date.
    
 
                                       45
<PAGE>
   
    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 above, but
without deduction for any applicable sales charge. Based on this calculation,
the average annual total returns of the Fund for the fiscal year ended October
31, 1996, for the five years ended October 31, 1996 and for the period March 30,
1989 through October 31, 1996 were 12.60%, 7.40% and 7.08%, respectively. These
returns are for Class B only; there were no other Classes of shares outstanding
on such date.
    
 
   
    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 the reduction for any sales charge) by the initial $1,000
investment and subtracting 1 from the result. Based upon the foregoing
calculation, the Fund's total return for the fiscal year ended October 31, 1996
was 12.60%, for the five years ended October 31, 1996 was 42.88%, and for the
period March 30, 1989 through October 31, 1996 was 68.02%. These returns are for
Class B only; there were no other Classes of shares outstanding on such date.
    
 
   
    The Fund may also advertise the growth of hypothetical investments of
$10,000, $50,000 and $100,000 in each Class of shares of the Fund by adding 1 to
the Fund's aggregate total return to date (expressed as a decimal and without
taking into account the effect of any applicable CDSC) and multiplying by
$9,575, $48,250 and $97,250 in the case of Class A (investments of $10,000,
$50,000 and $100,000 adjusted for the initial sales charge) or by $10,000,
$50,000 and $100,000 in the case of each of Class B, Class C and Class D, as the
case may be. Investments of $10,000, $50,000 and $100,000 in the Fund at
inception would have grown to $16,802, $84,010 and $168,020, respectively, at
October 31, 1996. This information is for Class B only; there were no other
Classes of shares outstanding on such date.
    
 
    The Fund from time to time may also advertise its performance relative to
certain performance rankings and indexes compiled by independent organizations.
 
DESCRIPTION OF SHARES

    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. On that
date, Wayne E. Hedien was also elected as a Trustee of the Fund, with his term
to commence on September 1, 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 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 own bad faith,
willful misfeasance, gross negligence, or reckless disregard of his duties. It
also provides that all third persons shall look solely to the Fund's property
for satisfaction of claims arising in connection with the affairs of the Fund.
With the exceptions stated, the Declaration of Trust provides that a Trustee,
officer, employee or agent is entitled to be indemnified against all liabilities
in connection with the affairs of the Fund.

additional series of shares (the proceeds of which would be invested in
separate, independently managed portfolios) and additional classes of shares
within any series. The Trustees have not presently authorized any such
additional series or classes of shares other than as set forth in the
Prospectus.
    
 
    The Trust shall be of unlimited duration subject to the provisions in the
Declaration of Trust concerning termination by action of the shareholders.

DEAN WITTER WORLD WIDE INCOME TRUST
REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND TRUSTEES
OF DEAN WITTER WORLD WIDE INCOME TRUST
 
In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Dean Witter World Wide Income Trust
(the "Fund") at October 31, 1996, 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 seven years in
the period then ended and for the period March 30, 1989 (commencement of
operations) through October 31, 1989, in conformity with generally accepted
accounting principles. These financial statements and financial highlights
(hereafter referred to as "financial statements") are the responsibility of the
Fund's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
financial statements in accordance with generally accepted auditing standards
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at October 31, 1996 by correspondence with the
custodian and brokers, provide a reasonable basis for the opinion expressed
above.

NOTES TO FINANCIAL STATEMENTS OCTOBER 31, 1996
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter World Wide Income Trust (the "Fund") is registered under the
Investment Company Act of 1940, as amended (the "Act"), as a non-diversified,
open-end management investment company. The Fund's primary investment objective
is to provide a high level of current income and, as a secondary objective,
seeks appreciation in the value of its assets. The Fund was organized as a
Massachusetts business trust on October 14, 1988 and commenced operations on
March 30, 1989.
 
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
these estimates. The following is a summary of significant accounting policies:
 
A. VALUATION OF INVESTMENTS -- (1) all portfolio securities for which
over-the-counter market quotations are readily available are valued at the
latest available bid price prior to the time of valuation; (2) listed options
are valued at the latest sale price on the exchange on which they are listed
unless no sales of such options have taken place that day, in which case they
will be valued at the mean between their latest bid and asked price; (3) futures
contracts are valued at the latest sale price on the commodities exchange on
which they trade unless the Trustees determine that such price does not reflect
their market value, in which case it will be valued at fair value as determined
by the Trustees; (4) when market quotations are not readily available, including
circumstances under which it is determined by the Investment Manager that sale
or bid prices are not reflective of a security's market value, portfolio
securities are valued at their fair value as determined in good faith under
procedures established by and under the general supervision of the Trustees
(valuation of debt securities for which market quotations are not readily
available may be based upon current market prices of securities which are
comparable in coupon, rating and maturity or an appropriate matrix utilizing
similar factors); (5) certain portfolio securities may be valued by an outside
pricing service approved by the Trustees. The pricing service utilizes a matrix
system incorporating security quality, maturity and coupon as the evaluation
model parameters, and/or research and evaluations by its staff, including review
of broker-dealer market price quotations, if available, in determining what it
believes is the fair valuation of the securities valued by such pricing service;
and (6) 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 WORLD WIDE INCOME TRUST
NOTES TO FINANCIAL STATEMENTS OCTOBER 31, 1996, 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.
Discounts are accreted over the life of the respective securities. Interest
income is accrued daily.
 
C. FUTURES CONTRACTS -- A futures contract is an agreement between two parties
to buy and sell financial instruments at a set price on a future date. Upon
entering into such a contract, the Fund is required to pledge to the broker cash
or U.S. Government securities equal to the minimum initial margin requirements
of the applicable futures exchange. Pursuant to the contract, the Fund agrees to
receive from or pay to the broker an amount of cash equal to the daily
fluctuation in the value of the contract which is known as variation margin.
Such receipts or payments are recorded by the Fund as unrealized gains or
losses. Upon closing of the contract, the Fund realizes a gain or loss equal to
the difference between the value of the contract at the time it was opened and
the value at the time it was closed.
 
D. FOREIGN CURRENCY TRANSLATION -- The books and records of the Fund are
maintained in U.S. dollars as follows: (1) the foreign currency market value of
investment securities, other assets and liabilities and forward contracts are
translated at the exchange rates prevailing at the end of the period; and (2)
purchases, sales, income and expenses are translated at the exchange rates
prevailing on the respective dates of such transactions. The resultant exchange
gains and losses are included in the Statement of Operations as realized and
unrealized gain/loss on foreign exchange transactions. Pursuant to U.S. Federal
income tax regulations, certain foreign exchange gains/losses included in
realized and unrealized gain/loss are included in or are a reduction of ordinary
income for federal income tax purposes. The Fund does not isolate that portion
of the results of operations arising as a result of changes in the foreign
exchange rates from the changes in the market prices of the securities.
 
E. FORWARD FOREIGN CURRENCY CONTRACTS -- The Fund may enter into forward foreign
currency contracts which are valued daily at the appropriate exchange rates. The
resultant unrealized exchange gains and losses are included in the Statement of
Operations as unrealized foreign currency gain or loss. The Fund records
realized gains or losses on delivery of the currency or at the time the forward
contract is extinguished (compensated) by entering into a closing transaction
prior to delivery.

F. 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 income to its shareholders.
Accordingly, no federal income tax provision is required.
 
G. 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 net assets of the Fund determined as of the close of each
business day: 0.75% to the portion of daily net assets not exceeding $250
million; 0.60% to the portion of daily net assets exceeding $250 million but not
exceeding $500 million; 0.50% to the portion of daily net assets exceeding $500
million but not exceeding $750 million; 0.40% to the portion of daily net assets
exceeding $750 million but not exceeding $1 billion; and 0.30% to the portion of
daily net assets exceeding $1 billion.
 
Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes, at its own expense, office space, facilities, equipment,
clerical, bookkeeping and certain legal services and pays the salaries of all
personnel, including officers of the Fund who are employees of the Investment
Manager. The Investment Manager also bears the cost of telephone services, heat,
light, power and other utilities provided to the Fund.

3. PLAN OF DISTRIBUTION
 
Shares of the Fund are distributed by 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 pursuant
to which the Fund pays the Distributor compensation, accrued daily and payable
monthly, at an annual rate of 0.85% of the lesser of: (a) the average daily
aggregate gross sales of the Fund's shares since the Fund's inception (not
including reinvestment of dividend or capital gains distributions) less the
average daily aggregate net asset value of the Fund's shares redeemed since the
Fund's inception upon which a contingent deferred sales charge has been imposed
or upon which such charge has been waived; or (b) the Fund's average daily net
assets. Amounts paid under the Plan are paid to the Distributor to compensate it
for the services provided and the expenses borne by it and others in the
distribution of the Fund's shares, including the payment of commissions for
sales of the Fund's shares and incentive compensation to, and expenses of,
account executives of Dean Witter Reynolds Inc., an affiliate of the Investment
Manager and Distributor, and other employees and selected broker-dealers, who
engage in or support distribution of the Fund's 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 be compensated under the Plan for its opportunity costs in
advancing such amounts, which compensation would be in the form of a carrying
charge on any unreimbursed expenses incurred by the Distributor.
 
Provided that the Plan continues in effect, any cumulative expenses incurred but
not yet recovered may be recovered through future distribution fees from the
Fund and contingent deferred sales charges from the Fund's shareholders.
 
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 $8,308,200 at
October 31, 1996.
 
The Distributor has informed the Fund that for year ended October 31, 1996, it
received approximately $110,000 in contingent deferred sales charges from
certain redemptions of the Fund's shares.

DEAN WITTER WORLD WIDE INCOME TRUST
NOTES TO FINANCIAL STATEMENTS OCTOBER 31, 1996, CONTINUED
 
As of October 31, 1996, the Fund had temporary book/tax differences primarily
attributable to the mark-to-market of open forward foreign currency exchange
contracts and compensated forward foreign currency exchange contracts and
permanent book/tax differences primarily attributable to foreign currency gains.
To reflect reclassifications arising from permanent book/tax differences for the
year ended October 31, 1996, accumulated net realized loss was charged and
accumulated undistributed net investment income was credited $2,601,781.
 
7. PURPOSES OF AND RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS
 
The Fund may enter into forward foreign currency contracts ("forward contracts")
to facilitate settlement of foreign currency denominated portfolio transactions
or to manage its foreign currency exposure or to sell, for a fixed amount of
U.S. dollars or other currency, the amount of foreign currency approximating the
value of some or all of its holdings denominated in such foreign currency or an
amount of foreign currency other than the currency in which the securities to be
hedged are denominated approximating the value of some or all of its holdings to
be hedged. Additionally, when the Investment Manager anticipates purchasing
securities at some time in the future, the Fund may enter into a forward
contract to purchase an amount of currency equal to some or all the value of the
anticipated purchase for a fixed amount of U.S. dollars or other currency.
 
To hedge against adverse interest rate, foreign currency and market risks, the
Fund may enter into written options on interest rate futures and interest rate
futures contracts ("derivative investments").
 
At October 31, 1996, there were no outstanding forward contracts other than
those used to facilitate settlement of foreign currency denominated portfolio
transactions and to manage foreign currency exposure.
 
These derivative instruments involve elements of market risk in excess of the
amount reflected in the Statement of Assets and Liabilities. The Fund bears the
risk of an unfavorable change in the foreign exchange rates underlying the
forward contracts. Risks may also arise upon entering into these contracts from
the potential inability of the counterparties to meet the terms of their
contracts.
 
At October 31, 1996 investments in securities of issuers in Spain and Italy
represented 48.1% of the Fund's net assets. These investments, which involve
risks and considerations not present with respect to U.S. securities, may be
affected by economic or political developments in these regions.

these estimates.
 
The following is a summary of significant accounting policies:
 
A. VALUATION OF INVESTMENTS -- (1) all portfolio securities for which
over-the-counter market quotations are readily available are valued at the
latest available bid price prior to the time of valuation; (2) futures contracts
are valued at the latest sale price on the commodities exchange on which they
trade unless the Trustees determine that such price does not reflect their
market value, in which case it will be valued at fair value as determined by the
Trustees; (3) when market quotations are not readily available, including
circumstances under which it is determined by Dean Witter InterCapital Inc. (the
"Investment Manager") that sale or bid prices are not reflective of a security's
market value, portfolio securities are valued at their fair value as determined
in good faith under procedures established by and under the general supervision
of the Trustees (valuation of debt securities for which market quotations are
not readily available may be based upon current market prices of securities
which are comparable in coupon, rating and maturity or an appropriate matrix
utilizing similar factors); (4) certain portfolio securities may be valued by an
outside pricing service approved by the Trustees. The pricing service may
utilize a matrix system incorporating security quality, maturity and coupon as
the evaluation model parameters, and/or research and evaluations by its staff,
including review of broker-dealer market price quotations, if available, in
determining what it believes is the fair valuation of the securities valued by
such pricing service; and (5) short-term debt securities having a maturity date
of more than sixty days at time of purchase are valued on a mark-to-market basis
until sixty days prior to maturity and thereafter at amortized cost based on
their value on the 61st day. Short-term debt securities having a maturity date
of sixty days or less at the time of purchase are valued at amortized cost.

B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Discounts are accreted over the life of the respective securities. Interest
income is accrued daily.
 
C. FUTURE CONTRACTS -- A futures contract is an agreement between two parties to
buy and sell financial instruments at a set price on a future date. Upon
entering into such a contract, the Fund is required to pledge to the broker cash
or U.S. Government securities equal to the minimum initial margin requirements
of the applicable futures exchange. Pursuant to the contract, the Fund agrees to
receive from or pay to the broker an amount of cash equal to the daily
fluctuation in the value of the contract which is known as variation margin.
Such receipts or payments are recorded by the Fund as unrealized gains or
losses. Upon closing of the contract, the Fund realizes a gain or loss equal to
the difference between the value of the contract at the time it was opened and
the value at the time it was closed.
 
D. FOREIGN CURRENCY TRANSLATION -- The books and records of the Fund are
maintained in U.S. dollars as follows: (1) the foreign currency market value of
investment securities, other assets and liabilities and forward foreign currency
contracts are translated at the exchange rates prevailing at the end of the
period; and (2) purchases, sales, income and expenses are translated at the
exchange rates prevailing on the respective dates of such transactions. The
resultant exchange gains and losses are included in the Statement of Operations
as realized and unrealized gain/loss on foreign exchange transactions. Pursuant
to U.S. Federal income tax regulations, certain foreign exchange gains/losses
included in realized and unrealized gain/loss are included in or are a reduction
of ordinary income for federal income tax purposes. The Fund does not isolate
that portion of the results of operations arising as a result of changes in the
foreign exchange rates from the changes in the market prices of the securities.
 
E. FORWARD FOREIGN CURRENCY CONTRACTS -- The Fund may enter into forward foreign
currency contracts which are valued daily at the appropriate exchange rates. The
resultant unrealized exchange gains and losses are included in the Statement of
Operations as unrealized foreign currency gain or loss. The Fund records
realized gains or losses on delivery of the currency or at the time the forward
contract is extinguished (compensated) by entering into a closing transaction
prior to delivery.

F. 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 income to its shareholders.
Accordingly, no federal income tax provision is required.
 
G. 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 the Investment Manager the
Fund pays a management fee, accrued daily and payable monthly, by applying the
following annual rates to the net assets of the Fund determined as of the close
of each business day: 0.75% to the portion of daily net assets not exceeding
$250 million; 0.60% to the portion of daily net assets exceeding $250 million
but not exceeding $500 million; 0.50% to the portion of daily net assets
exceeding $500 million but not exceeding $750 million; 0.40% to the portion of
daily net assets exceeding $750 million but not exceeding $1 billion; and 0.30%
to the portion of daily net assets exceeding $1 billion.
 
Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes, at its own expense, office space, facilities, equipment,
clerical, bookkeeping and certain legal services and pays the salaries of all
personnel, including officers of the Fund who are employees of the Investment
Manager. The Investment Manager also bears the cost of telephone services, heat,
light, power and other utilities provided to the Fund.

3. PLAN OF DISTRIBUTION
 
Shares of the Fund are distributed by 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 pursuant
to which the Fund pays the Distributor compensation, accrued daily and payable
monthly, at an annual rate of 0.85% of the lesser of: (a) the average daily
aggregate gross sales of the Fund's shares since the Fund's inception (not
including reinvestment of dividend or capital gains distributions) less the
average daily aggregate net asset value of the Fund's shares redeemed since the
Fund's inception upon which a contingent deferred sales charge has been imposed
or upon which such charge has been waived; or (b) the Fund's average daily net
assets. Amounts paid under the Plan are paid to the Distributor to compensate it
for the services provided and the expenses borne by it and others in the
distribution of the Fund's shares, including the payment of commissions for
sales of the Fund's shares and incentive compensation to, and expenses of,
account executives of Dean Witter Reynolds Inc., an affiliate of the Investment
Manager and Distributor, and others, who engage in or support distribution of
the Fund's shares or who service shareholder accounts, including overhead and
telephone expenses, 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 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 distribution expenses.
 
Provided that the Plan continues in effect, any cumulative expenses incurred but
not yet recovered may be recovered through future distribution fees from the
Fund and contingent deferred sales charges from the Fund's shareholders.
 
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 $8,311,248 at
April 30, 1997.
 
The Distributor has informed the Fund that for the six months ended April 30,
1997, it received approximately $33,000 in contingent deferred sales charges
from certain redemptions of the Fund's shares. The Fund's 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 six months ended April 30, 1997 aggregated
$91,473,208 and $101,796,587, respectively. Included in the aforementioned are
purchases and sales of U.S. Government securities of $38,000,133 and
$11,470,670, respectively.
 
Dean Witter Trust Company, an affiliate of the Investment Manager and
Distributor, is the Fund's transfer agent. At April 30, 1997, the Fund had
transfer agent fees and expenses payable of approximately $16,000.
 
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 six months ended April 30, 1997
included in Trustees' fees and expenses in the Statement of Operations amounted
to $838. At April 30, 1997, the Fund had an accrued pension liability of $48,634
which is included in accrued expenses in the Statement of Assets and
Liabilities.

DEAN WITTER WORLD WIDE INCOME TRUST
NOTES TO FINANCIAL STATEMENTS APRIL 30, 1997 (UNAUDITED) CONTINUED
 
As of October 31, 1996, the Fund had temporary book/tax differences primarily
attributable to the mark-to-market of open forward foreign currency exchange
contracts and compensated forward foreign currency exchange contracts.
 
7. PURPOSES OF AND RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS
 
The Fund may enter into forward foreign currency contracts ("forward contracts")
to facilitate settlement of foreign currency denominated portfolio transactions
or to manage its foreign currency exposure or to sell, for a fixed amount of
U.S. dollars or other currency, the amount of foreign currency approximating the
value of some or all of its holdings denominated in such foreign currency or an
amount of foreign currency other than the currency in which the securities to be
hedged are denominated approximating the value of some or all of its holdings to
be hedged. Additionally, when the Investment Manager anticipates purchasing
securities at some time in the future, the Fund may enter into a forward
contract to purchase an amount of currency equal to some or all the value of the
anticipated purchase for a fixed amount of U.S. dollars or other currency.
 
To hedge against adverse interest rate, foreign currency and market risks, the
Fund may enter into written options on interest rate futures and interest rate
futures contracts ("derivative instruments").
 
These derivative instruments involve elements of market risk in excess of the
amount reflected in the Statement of Assets and Liabilities. The Fund bears the
risk of an unfavorable change in the foreign exchange rates underlying the
forward contracts. Risks may also arise upon entering into these contracts from
the potential inability of the counterparties to meet the terms of their
contracts.
 
At April 30, 1997, there were no outstanding forward contracts other than those
used to facilitate settlement of foreign currency denominated portfolio
transactions and to manage foreign currency exposure.

RATINGS
 
MOODY'S INVESTORS SERVICE INC. ("MOODY'S")
 
                                  BOND RATINGS
 
<TABLE>
<S>        <C>
Aaa        Bonds which are rated Aaa are judged to be of the best quality. They carry the
           smallest degree of investment risk and are generally referred to as "gilt edge."
           Interest payments are protected by a large or by an exceptionally stable margin and
           principal is secure. While the various protective elements are likely to change,
           such changes as can be visualized are most unlikely to impair the fundamentally
           strong position of such issues.
 
Aa         Bonds which are rated Aa are judged to be of high quality by all standards.
           Together with the Aaa group they comprise what are generally known as high grade
           bonds. They are rated lower than the best bonds because margins of protection may
           not be as large as in Aaa securities or fluctuation of protective elements may be
           of greater amplitude or there may be other elements present which make the
           long-term risks appear somewhat larger than in Aaa securities.
 
A          Bonds which are rated A possess many favorable investment attributes and are to be
           considered as upper medium grade obligations. Factors giving security to principal
           and interest are considered adequate, but elements may be present which suggest a
           susceptibility to impairment sometime in the future.
 
Baa        Bonds which are rated Baa are considered as medium grade obligations; i.e., they
           are neither highly protected nor poorly secured. Interest payments and principal
           security appear adequate for the present but certain protective elements may be
           lacking or may be characteristically unreliable over any great length of time. Such
           bonds lack outstanding investment characteristics and in fact have speculative
           characteristics as well.
 
           Bonds rated Aaa, Aa, A and Baa are considered investment grade bonds.
 
Ba         Bonds which are rated Ba are judged to have speculative elements; their future
           cannot be considered as well assured. Often the protection of interest and
           principal payments may be very moderate, and therefore not well safeguarded during
           both good and bad times over the future. Uncertainty of position characterizes
           bonds in this class.
 
B          Bonds which are rated B generally lack characteristics of desirable investments.
           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 represent 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.

    RATING REFINEMENTS: Moody's may apply numerical modifiers, 1, 2, and 3 in
each generic rating classification from Aa through B in its corporate and
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.

                            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. 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 catagories.
 
STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S")
 
                                  BOND RATINGS
 
    A Standard & Poor's 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.
 
<TABLE>
<S>        <C>
AAA        Debt rated AAA has the highest rating assigned by Standard & Poor's. Capacity to
           pay interest and repay principal is extremely strong.
 
AA         Debt rated AA has a very strong capacity to pay interest and repay principal and
           differs from the highest-rated issues only in small degree.
 
A          Debt rated A has a strong capacity to pay interest and repay principal although
           they are somewhat more susceptible to the adverse effects of changes in
           circumstances and economic conditions than debt in higher-rated categories.
 
BBB        Debt rated BBB is regarded as having an adequate capacity to pay interest and repay
           principal. Whereas it normally exhibits adequate protection parameters, adverse
           economic conditions or changing circumstances are more likely to lead to a weakened
           capacity to pay interest and repay principal for debt in this category than for
           debt in higher-rated categories.
 
           Bonds rated AAA, AA, A and BBB are considered investment grade bonds.
 
BB         Debt rated BB has less near-term vulnerability to default than other speculative
           grade debt. However, it faces major ongoing uncertainties or exposure to adverse
           business, financial or economic conditions which could lead to inadequate capacity
           to meet timely interest and principal payment.
 
B          Debt rated B has a greater vulnerability to default but presently has the capacity
           to meet interest payments and principal repayments. Adverse business, financial or
           economic conditions would likely impair capacity or willingness to pay interest and
           repay principal.

<PAGE>
<TABLE>
<S>        <C>
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 default. The D rating is assigned on the day an interest or
           principal payment is missed.
 
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.
</TABLE>
 
                            COMMERCIAL PAPER RATINGS
 
    Standard and Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days. The commercial paper rating is not a recommendation to purchase or
sell a security. The ratings are based upon current information furnished by the
issuer or obtained by S&P from other sources it considers reliable. The ratings
may be changed, suspended, or withdrawn as a result of changes in or
unavailability of such information. Ratings are graded into group categories,
ranging from "A" for the highest quality obligations to "D" for the lowest. The
categories are as follows:
 
    Issues assigned A ratings are regarded as having the greatest capacity for
timely payment. Issues in this category are further refined with the designation
1, 2 and 3 to indicate the relative degree of safety.
 
<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.
   
         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 


                                          3
<PAGE>

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.

execution by a majority of the then Trustees of an instrument setting forth such
establishment and designation and the relative rights, preferences, voting

and the Additional Classes; and be it further

RESOLVED, pursuant to Section 6.9(h) of the Declaration, all shares of the Trust
held prior to July 28, 1997 are hereby designated as Class B shares of the

                               DEAN WITTER FUNDS
                              MULTIPLE CLASS PLAN
                             PURSUANT TO RULE 18f-3
 
INTRODUCTION
 
    This plan (the "Plan") is adopted pursuant to Rule 18f-3(d) of the
Investment Company Act of 1940, as amended (the "1940 Act"), and will be
effective as of July 28, 1997. The Plan relates to shares of the open-end
investment companies to which Dean Witter InterCapital Inc. acts as investment
manager, that are listed on Schedule A, as may be amended from time to time
(each, a "Fund" and collectively, the "Funds"). The Funds are distributed
pursuant to a system (the "Multiple Class System") in which each class of shares
(each, a "Class" and collectively, the "Classes") of a Fund represents a pro
rata interest in the same portfolio of investments of the Fund and differs only
to the extent outlined below.
 
I.  DISTRIBUTION ARRANGEMENTS
 
    One or more Classes of shares of the Funds are offered for purchase by
investors with the sales load structures described below. In addition, pursuant
to Rule 12b-1 under the 1940 Act, the Funds have each adopted a Plan of
Distribution (the "12b-1 Plan") under which shares of certain Classes are
subject to the service and/or distribution fees ("12b-1 fees") described below.
 
    1.  CLASS A SHARES
 
    Class A shares are offered with a front-end sales load ("FESL"). The
schedule of sales charges applicable to a Fund and the circumstances under which
the sales charges are subject to reduction are set forth in each Fund's current
prospectus. As stated in each Fund's current prospectus, Class A shares may be
purchased at net asset value (without a FESL): (i) in the case of certain large
purchases of such shares; and (ii) by certain limited categories of investors,
in each case, under the circumstances and conditions set forth in each Fund's
current prospectus. Class A shares purchased at net asset value may be subject
to a contingent deferred sales charge ("CDSC") on redemptions made within one
year of purchase. Further information relating to the CDSC, including the manner
in which it is calculated, is set forth in paragraph 6 below. Class A shares are
also subject to payments under each Fund's 12b-1 Plan to reimburse Dean Witter
Distributors Inc., Dean Witter Reynolds Inc. ("DWR"), its affiliates and other
broker-dealers for distribution expenses incurred by them specifically on behalf
of the Class, assessed at an annual rate of up to 0.25% of average daily net
assets. The entire amount of the 12b-1 fee represents a service fee within the
meaning of National Association of Securities Dealers, Inc. ("NASD") guidelines.
 
    2.  CLASS B SHARES
 
    Class B shares are offered without a FESL, but will in most cases be subject
to a six-year declining CDSC which is calculated in the manner set forth in
paragraph 6 below. Class B shares purchased by certain qualified
employer-sponsored benefit plans are subject to a three-year declining CDSC
which is calculated in the manner set forth in paragraph 6 below. The schedule
of CDSC charges applicable to each Fund is set forth in each Fund's current
prospectus. With the exception of certain of the Funds which have a different
formula described below (Dean Witter American Value Fund, Dean Witter Natural
Resource Development Securities Inc., Dean Witter Strategist Fund and Dean
Witter Dividend Growth Securities Inc.)(1), Class B
 
- ------------
 
(1)The payments under the 12b-1 Plan for each of Dean Witter American Value
Fund, Dean Witter Natural Resource Development Securities Inc. and Dean Witter
Dividend Growth Securities Inc. are assessed at the annual rate of 1.0% of the
lesser of: (a) the average daily aggregate gross sales of the Fund's Class B
shares since the inception of the Fund's Plan (not including reinvestment of
dividends or capital gains distributions), less the average daily aggregate net
asset value of the Fund's Class B shares redeemed since the Plan's inception
upon which a contingent deferred sales charge has been imposed or waived, or (b)
the average daily net assets of Class B attributable to shares issued, net of
related shares redeemed, since inception of the Plan. The payments under the
12b-1 Plan for the Dean Witter Strategist Fund are assessed at the annual rate
of: (i) 1% of the lesser of (a) the average daily aggregate gross sales of the
Fund's Class B shares since the effectiveness of the first amendment of the Plan
on November 8, 1989 (not including reinvestment of dividends or capital gains
distributions), less the average daily aggregate net asset value of the Fund's
Class B shares redeemed since the effectiveness of the first amended Plan, upon
which a contingent deferred sales charge has been imposed or waived, or (b) the
average daily net assets of Class B attributable to shares issued, net of
related shares redeemed, since the effectiveness of the first amended Plan; plus
(ii) 0.25% of the average daily net assets of Class B attributable to shares
issued, net of related shares redeemed, prior to effectiveness of the first
amended Plan.
 
                                       1
<PAGE>
shares are also subject to a fee under each Fund's respective 12b-1 Plan,
assessed at the annual rate of up to 1.0% of either: (a) the lesser of (i) the
average daily aggregate gross sales of the Fund's Class B shares since the
inception of the Fund (not including reinvestment 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 (ii) the average daily net assets of Class B; or (b) the
average daily net assets of Class B. A portion of the 12b-1 fee equal to up to
0.25% of the Fund's average daily net assets is characterized as a service fee
within the meaning of the NASD guidelines and the remaining portion of the 12b-1
fee, if any, is characterized as an asset-based sales charge. Also, Class B
shares have a conversion feature ("Conversion Feature") under which such shares
convert to Class A shares after a certain holding period. Details of the
Conversion Feature are set forth in Section IV below.
 
    3.  CLASS C SHARES
 
    Class C shares are offered without imposition of a FESL, but will in most
cases be subject to a CDSC of 1.0% on redemptions made within one year after
purchase. Further information relating to the CDSC is set forth in paragraph 6
below. In addition, Class C shares, under each Fund's 12b-1 Plan, are subject to
12b-1 payments to reimburse Dean Witter Distributors Inc., DWR, its affiliates
and other broker-dealers for distribution expenses incurred by them specifically
on behalf of the Class, assessed at the annual rate of up to 1.0% of the average
daily net assets of the Class. A portion of the 12b-1 fee equal to up to 0.25%
of the Fund's average daily net assets is characterized as a service fee within
the meaning of NASD guidelines. Unlike Class B shares, Class C shares do not
have the Conversion Feature.
 
    4.  CLASS D SHARES
 
    Class D shares are offered without imposition of a FESL, CDSC or a 12b-1 fee
for purchases of Fund shares by (i) investors meeting an initial minimum
investment requirement and (ii) certain other limited categories of investors,
in each case, as may be approved by the Boards of Directors/Trustees of the
Funds and as disclosed in each Fund's current prospectus.
 
    5.  ADDITIONAL CLASSES OF SHARES
 
    The Boards of Directors/Trustees of the Funds have the authority to create
additional Classes, or change existing Classes, from time to time, in accordance
with Rule 18f-3 under the 1940 Act.
 
    6.  CALCULATION OF THE CDSC
 
    Any applicable CDSC is calculated based upon the lesser of net asset value
of the shares at the time of purchase or at the time of redemption. The CDSC
does not apply to amounts representing an increase in share value due to capital
appreciation and shares acquired through the reinvestment of dividends or
capital gains distributions. The CDSC schedule applicable to a Fund and the
circumstances in which the CDSC is subject to waiver are set forth in each
Fund's prospectus.
 
II.  EXPENSE ALLOCATIONS
 
    Expenses incurred by a Fund are allocated among the various Classes of
shares pro rata based on the net assets of the Fund attributable to each Class,
except that 12b-1 fees relating to a particular Class are 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 Fund's Board of Directors/Trustees.
 
III.  CLASS DESIGNATION
 
    All shares of the Funds held prior to July 28, 1997 (other than the shares
held by certain employee benefit plans established by DWR and its affiliate, SPS
Transaction Services, Inc., shares of Funds offered with a FESL, and shares of
Dean Witter Balanced Growth Fund and Dean Witter Balanced Income Fund) have been
designated Class B shares. Shares held prior to July 28, 1997 by such employee
benefit plans have been designated Class D shares. Shares held prior to July 28,
1997 of Funds offered with a FESL have been designated Class D shares. In
addition, shares of Dean Witter American Value Fund purchased prior to April 30,
1984, shares of Dean Witter Strategist Fund purchased prior to November 8, 1989
and shares of Dean Witter Natural Resource Development Securities Inc. and Dean
Witter Dividend Growth Securities Inc. purchased prior to July 2, 1984 (with
respect to such shares of each Fund, including such proportion of shares
acquired through reinvestment of dividends and capital gains distributions as
the total number of shares acquired prior to each of the preceding dates in this
sentence bears to the total number of shares purchased and owned by the
shareholder of that Fund) have been designated Class D shares. Shares of Dean
Witter Balanced Growth Fund and Dean Witter Balanced Income Fund held prior to
July 28, 1997 have
 
                                       2
<PAGE>
been designated Class C shares except that shares of Dean Witter Balanced Growth
Fund and Dean Witter Balanced Income Fund held prior to July 28, 1997 that were
acquired in exchange for shares of an investment company offered with a CDSC
have been designated Class B shares and those that were acquired in exchange for
shares of an investment company offered with a FESL have been designated Class A
shares.
 
IV.  THE CONVERSION FEATURE
 
    Class B shares held before May 1, 1997 will convert to Class A shares in
May, 2007, except that Class B shares which are purchased before July 28, 1997
by trusts for which Dean Witter Trust Company ("DWTC") or Dean Witter Trust FSB
("DWTFSB") provides discretionary trustee services will convert to Class A
shares on or about August 29, 1997 (the CDSC will not be applicable to such
shares upon the conversion). In all other instances, Class B shares of each Fund
will automatically convert 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.
Conversions will be effected once a month. The 10 year period will be 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. Except as set forth below, 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 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 held by a 401(k) plan or other employer-sponsored plan
qualified under Section 401(a) of the Internal Revenue Code (the "Code") and for
which DWTC or DWTFSB serves as Trustee or the 401(k) Support Services Group of
DWR serves as recordkeeper, all Class B shares will convert to Class A shares on
the conversion date of the first shares of a Fund purchased by that plan. In the
case of Class B shares previously exchanged for shares of an "Exchange Fund" (as
such term is defined in the prospectus of each Fund), 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 Fund, the holding period resumes on the last day of the month in
which Class B shares are reacquired.
 
    Effectiveness of the Conversion Feature is subject to the continuing
availability of a ruling of the Internal Revenue Service or an opinion of
counsel to the effect that (i) the conversion of shares does not constitute a
taxable event under the 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 fees under the applicable Fund's 12b-1 Plan.
 
V.  EXCHANGE PRIVILEGES
 
    Shares of each Class may be exchanged for shares of the same Class of the
other Funds and for shares of certain other investment companies without the
imposition of an exchange fee as described in the prospectuses and statements of
additional information of the Funds. The exchange privilege of each Fund may be
terminated or revised at any time by the Fund upon such notice as may be
required by applicable regulatory agencies as described in each Fund's
prospectus.
 
VI.  VOTING
 
    Each Class shall have exclusive voting rights on any matter that relates
solely to its 12b-1 Plan, except that Class B shareholders will have the right
to vote on any proposed material increase in Class A's expenses, including
payments under the Class A 12b-1 Plan, if such proposal is submitted separately
to Class A shareholders. If the amount of expenses, including payments under the
Class A 12b-1 Plan, is increased materially without the approval of Class B
shareholders, the Fund will establish a new Class A for Class B shareholders
whose shares automatically convert on the same terms as applied to Class A
before the increase. In addition, each Class shall have separate voting rights
on any matter submitted to shareholders in which the interests of one Class
differ from the interests of any other Class.

                        INVESTMENT MANAGEMENT AGREEMENT
 
    AGREEMENT made as of the 31st day of May, 1997 by and between Dean Witter
World Wide Income Trust, an unincorporated business trust organized under the
laws of the Commonwealth of Massachusetts (hereinafter called the "Fund"), and
Dean Witter InterCapital Inc., a Delaware corporation (hereinafter called the
"Investment Manager"):

investment company and is registered as such under the Investment Company Act of
1940, as amended (the "Act"); and
 
    WHEREAS, The Investment Manager is registered as an investment adviser under
the Investment Advisers Act of 1940, and engages in the business of acting as

contained, the Fund and the Investment Manager agree as follows:
 
    1. The Fund hereby retains the Investment Manager to act as investment

of its obligations under this Agreement. Without limiting the generality of the
foregoing, the staff and personnel of the Investment Manager shall be deemed to
include persons employed or otherwise retained by the Investment Manager to
furnish statistical and other factual data, advice regarding economic factors
and trends, information with respect to technical and scientific developments,
and such other information, advice and assistance as the Investment Manager may
desire. The Investment Manager shall, as agent for the Fund, maintain the Fund's
records and books of account (other than those maintained by the Fund's transfer
agent, registrar, custodian and other agencies). All such books and records so
maintained shall be the property of the Fund and, upon request therefor, the
Investment Manager shall surrender to the Fund such of the books and records so
requested.
 
    3. The Fund will, from time to time, furnish or otherwise make available to
the Investment Manager such financial reports, proxy statements and other
information relating to the business and affairs of the Fund as the Investment
Manager may reasonably require in order to discharge its duties and obligations
hereunder.
 
    4. The Investment Manager shall bear the cost of rendering the investment
management and supervisory services to be performed by it under this
Agreement, and shall, at its own expense, pay the compensation of the officers
and employees, if any, of the Fund, and provide such office space, facilities
and equipment
<PAGE>
and such clerical help and bookkeeping services as the Fund shall reasonably
require in the conduct of its business. The Investment Manager shall also bear
the cost of telephone service, heat, light, power and other utilities provided
to the Fund.
 
    5. The Fund assumes and shall pay or cause to be paid all 
other expenses of the Fund, including without limitation: fees pursuant to 
any plan of distribution that the Fund may adopt; the charges and expenses of 
any registrar, any custodian or depository appointed by the Fund for the 
safekeeping of its cash, portfolio securities or commodities and other 
property, and any stock transfer or dividend agent or agents appointed by the 
Fund; brokers' commissions chargeable to the Fund in connection with 
portfolio transactions to which the Fund is a party; all taxes, including 
securities or commodities issuance and transfer taxes, and fees payable by 
the Fund to federal, state or other governmental agencies; the cost and 
expense of engraving or printing certificates representing shares of the 
Fund; all costs and expenses in connection with the registration and 
maintenance of registration of the Fund and its shares with the Securities 
and Exchange Commission and various states and other jurisdictions (including 
filing fees and legal fees and disbursements of counsel); 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 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 the 
payment of any dividend, distribution, withdrawal or redemption, whether in 
shares or in cash; charges and expenses of any outside service used for 
pricing of the Fund's shares; charges and expenses of legal counsel, 
including counsel to the Trustees of the Fund who are not interested persons 
(as defined in the Act) of the Fund or the Investment Manager, and of 
independent accountants, in connection with any matter relating to the Fund; 
membership dues of industry associations; interest payable 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 related thereto); and all other 
charges and costs of the Fund's operation unless otherwise explicitly 
provided herein.
 
    6. For the services to be rendered, the facilities furnished, and the 
expenses assumed by the Investment Manager, the Fund shall pay to the 
Investment Manager monthly compensation determined by applying the following 
annual rates to the Fund's daily net assets: 0.75% of daily net assets up to 
$250 million; 0.60% of the next $250 million; 0.50% of the next $250 million; 
0.40% of the next $250 million; and 0.30% of daily net assets over $1 
billion. Except as hereinafter set forth, compensation under this Agreement 
shall be calculated and accrued daily and the amounts of the daily accruals 
shall be paid monthly. Such calculations shall be made by applying 1/365ths 
of the annual rates to the Fund's net assets each day determined as of the 
close of business on that day or the last previous business day. If this 
Agreement becomes effective subsequent to the first day of a month or shall 
terminate before the last day of a month, compensation for that part of the 
month this Agreement is in effect shall be prorated in a manner consistent 
with the calculation of the fees as set forth above.
 
    Subject to the provisions of paragraph 7 hereof, payment of the Investment
Manager's compensation for the preceding month shall be made as promptly as
possible after completion of the computations contemplated by paragraph 7
hereof.
 
    7. In the event the operating expenses of the Fund, including amounts
payable to the Investment Manager pursuant to paragraph 6 hereof, for any
fiscal year ending on a date on which this Agreement is in effect, exceed the
expense limitations applicable to the Fund imposed by state securities laws or
regulations thereunder, as such limitations may be raised or lowered from time
to time, the Investment Manager shall reduce its management fee to the extent of
such excess and, if required, pursuant to any such laws or regulations, will
reimburse the Fund for annual operating expenses in excess of any expense
limitation that may be applicable; provided, however, there shall be excluded
from such expenses the amount of any interest, taxes, brokerage commissions,
distribution fees and extraordinary expenses (including but not limited to legal
claims and liabilities and litigation costs and any indemnification related
thereto) paid or
 
                                       2
<PAGE>
payable by the Fund. Such reduction, if any, shall be computed and accrued
daily, shall be settled on a monthly basis, and shall be based upon the expense
limitation applicable to the Fund as at the end of the last business day of the
month. Should two or more such expense limitations be applicable as at the end
of the last business day of the month, that expense limitation which results in
the largest reduction in the Investment Manager's fee shall be applicable.
 
    For purposes of this provision, should any applicable expense limitation be
based upon the gross income of the Fund, such gross income shall include, but
not be limited to, interest on debt securities in the Fund's portfolio accrued
to and including the last day of the Fund's fiscal year, and dividends declared
on equity securities in the Fund's portfolio, the record dates for which fall on
or prior to the last day of such fiscal year, but shall not include gains from
the sale of securities.
 
    8. The Investment Manager will use its best efforts in the supervision and
management of the investment activities of the Fund, but in the absence
of willful misfeasance, bad faith, gross negligence or reckless disregard of its
obligations hereunder, the Investment Manager shall not be liable to the Fund or
any of its investors for any error of judgment or mistake of law or for any act
or omission by the Investment Manager or for any losses sustained by the Fund or
its investors.
 
    9. Nothing contained in this Agreement shall prevent the Investment Manager
or any affiliated person of the Investment Manager from acting as
investment adviser or manager for any other person, firm or corporation and
shall not in any way bind or restrict the Investment Manager or any such
affiliated person from buying, selling or trading any securities or commodities
for their own accounts or for the account of others for whom they may be acting.
Nothing in this Agreement shall limit or restrict the right of any Trustee,
officer or employee of the Investment Manager to engage in any other business or
to devote his or her time and attention in part to the management or other
aspects of any other business whether of a similar or dissimilar nature.
 
    10. This Agreement shall remain in effect until April 30, 1999 and from year
to year thereafter provided such continuance is approved at least
annually by the vote of holders of a majority, as defined in the Investment
Company Act of 1940, as amended (the "Act"), of the outstanding voting
securities of the Fund or by the Trustees of the Fund; provided that in either
event such continuance is also approved annually by the vote of a majority of
the Trustees of the Fund who are not parties to this 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; provided,
however, that (a) the Fund may, at any time and without the payment of any
penalty, terminate this Agreement upon thirty days' written notice to the
Investment Manager, either by majority vote of the Trustees of the Fund or by
the vote of a majority of the outstanding voting securities of the Fund; (b)
this Agreement shall immediately terminate in the event of its assignment (to
the extent required by the Act and the rules thereunder) unless such automatic
terminations shall be prevented by an exemptive order of the Securities and
Exchange Commission; and (c) the Investment Manager may terminate this Agreement
without payment of penalty on thirty days' written notice to the Fund. Any
notice under this Agreement shall be given in writing, addressed and delivered,
or mailed post-paid, to the other party at the principal office of such party.
 
    11. This Agreement may be amended by the parties without the vote or consent
of the shareholders of the Fund to supply any omission, to cure, correct
or supplement any ambiguous, defective or inconsistent provision hereof, or if
they deem it necessary to conform this Agreement to the requirements of
applicable federal laws or regulations, but neither the Fund nor the Investment
Manager shall be liable for failing to do so.
 
    12. This Agreement shall be construed in accordance with the laws of the
State of New York and the applicable provisions of the Act. To the extent
the applicable law of the State of New York, or any of the provisions herein,
conflicts with the applicable provisions of the Act, the latter shall control.
 
    13. The Investment Manager and the Fund each agree that the name "Dean
Witter," which comprises a component of the Fund's name, is a property
right of Dean Witter Reynolds Inc. The Fund agrees and consents that (i) it will
only use the name "Dean Witter" as a component of its name and for no other
 
                                       3
<PAGE>
purpose, (ii) it will not purport to grant to any third party the right to use
the name "Dean Witter" for any purpose, (iii) the Investment Manager or its
parent, Morgan Stanley, Dean Witter, Discover & Co., or any corporate affiliate
of the Investment Manager's parent, may use or grant to others the right to use
the name "Dean Witter," or any combination or abbreviation thereof, as all or a
portion of a corporate or business name or for any commercial purpose, including
a grant of such right to any other investment company, (iv) at the request of
the Investment Manager or its parent, the Fund will take such action as may be
required to provide its consent to the use of the name "Dean Witter," or any
combination or abbreviation thereof, by the Investment Manager or its parent or
any corporate affiliate of the Investment Manager's parent, or by any person to
whom the Investment Manager or its parent or any corporate affiliate of the
Investment Manager's parent shall have granted the right to such use, and (v)
upon the termination of any investment advisory agreement into which the
Investment Manager and the Fund may enter, or upon termination of affiliation of
the Investment Manager with its parent, the Fund shall, upon request by the
Investment Manager or its parent, cease to use the name "Dean Witter" as a
component of its name, and shall not use the name, or any combination or
abbreviation thereof, as a part of its name or for any other commercial purpose,
and shall cause its officers, Trustees and shareholders to take any and all
actions which the Investment Manager or its parent may request to effect the
foregoing and to reconvey to the Investment Manager or its parent any and all
rights to such name.
 
    14. The Declaration of Trust establishing Dean Witter World Wide Income
Trust, dated October 13, 1988, a copy of which, together with all
amendments thereto (the "Declaration"), is on file in the office of the
Secretary of the Commonwealth of Massachusetts, provides that the name Dean
Witter World Wide Income Trust refers to the Trustees under the Declaration
collectively as Trustees, but not as individuals or personally; and no Trustee,
shareholder, officer, employee or agent of Dean Witter World Wide Income Trust
shall be held to any personal liability, nor shall resort be had to their
private property for the satisfaction of any obligation or claim or otherwise,
in connection with the affairs of said Dean Witter World Wide Income Trust, but
the Trust Estate only shall be liable.
 
    IN WITNESS WHEREOF, the parties hereto have executed and delivered this
Agreement on the day and year first above written in New York, New York.

                               DEAN WITTER FUNDS

                             DISTRIBUTION AGREEMENT
 
    AGREEMENT made as of this 31st day of May, 1997 between each of the open-end
investment  companies to which Dean Witter  InterCapital Inc. acts as investment
manager, that are  listed on Schedule  A, as may  be amended from  time to  time
(each,  a "Fund"  and collectively, the  "Funds"), and  Dean Witter Distributors
Inc., a Delaware corporation (the "Distributor").
 
                              W I T N E S S E T H:
 
    WHEREAS, each Fund is registered as an open-end investment company under the
Investment Company Act of 1940,  as amended (the "1940 Act"),  and it is in  the
interest of each Fund to offer its shares for sale continuously, and
 
    WHEREAS,  each Fund and the Distributor wish to enter into an agreement with
each other with respect to the  continuous offering of each Fund's  transferable
shares, of $0.01 par value (the "Shares"), to commence on the date listed above,
in  order to promote the growth of  each Fund and facilitate the distribution of
its shares.
 
    NOW, THEREFORE, the parties agree as follows:
 
    SECTION 1.  APPOINTMENT OF THE DISTRIBUTOR.
 
    (a) Each Fund hereby appoints  the Distributor as the principal  underwriter
and  distributor of the Fund to sell Shares to the public on the terms set forth
in this Agreement and that Fund's prospectus and the Distributor hereby  accepts
such appointment and agrees to act hereunder. Each Fund, during the term of this
Agreement,  shall sell Shares  to the Distributor upon  the terms and conditions
set forth herein.
 
    (b) The Distributor  agrees to  purchase Shares,  as principal  for its  own
account,  from  each Fund  and to  sell  Shares as  principal to  investors, and
securities dealers, including Dean Witter Reynolds Inc. ("DWR"), an affiliate of
the Distributor, upon the terms described  herein and in that Fund's  prospectus
(the  "Prospectus")  and statement  of  additional information  included  in the
Fund's registration statement (the "Registration Statement") most recently filed
from time to time  with the Securities and  Exchange Commission (the "SEC")  and
effective under the Securities Act of 1933, as amended (the "1933 Act"), and the
1940 Act or as the Prospectus may be otherwise amended or supplemented and filed
with the SEC pursuant to Rule 497 under the 1933 Act.
 
    SECTION  2.   EXCLUSIVE  NATURE OF  DUTIES.   The  Distributor shall  be the
exclusive principal underwriter and  distributor of each  Fund, except that  the
exclusive  rights granted to the Distributor to  sell the Shares shall not apply
to  Shares  issued  by  each  Fund:  (i)  in  connection  with  the  merger   or
consolidation  of any other investment company  or personal holding company with
the Fund or the  acquisition by purchase or  otherwise of all (or  substantially
all)  the assets or the outstanding shares of any such company by the Fund; (ii)
pursuant to reinvestment of dividends  or capital gains distributions; or  (iii)
pursuant to the reinstatement privilege afforded redeeming shareholders.
 
    SECTION 3.  PURCHASE OF SHARES FROM EACH FUND.
 
    (a)  The Distributor shall have  the right to buy  from each Fund the Shares
needed, but  not more  than the  Shares needed  (except for  clerical errors  in
transmission),   to  fill  unconditional  orders  for  Shares  placed  with  the
Distributor by investors or securities dealers. The price which the  Distributor
shall  pay for  the Shares  so purchased from  the Fund  shall be  the net asset
value, determined as set forth in the Prospectus, used in determining the public
offering price on which such orders were based.
 
    (b) The Shares are to  be resold by the  Distributor at the public  offering
price  of Shares as set  forth in the Prospectus,  to investors or to securities
dealers, including DWR, who  have entered into  selected dealer agreements  with
the  Distributor upon  the terms  and conditions set  forth in  Section 7 hereof
("Selected Dealers").
 
                                       1
<PAGE>
    (c) Each Fund  shall have the  right to suspend  the sale of  the Shares  at
times  when  redemption is  suspended pursuant  to the  conditions set  forth in
Section (f) hereof. Each Fund shall also  have the right to suspend the sale  of
the  Shares if trading on the New York Stock Exchange shall have been suspended,
if a  banking  moratorium  shall have  been  declared  by federal  or  New  York
authorities,  or if there shall have  been some other extraordinary event which,
in the judgment of a Fund, makes it impracticable to sell its Shares.
 
    (d) Each Fund, or  any agent of  a Fund designated in  writing by the  Fund,
shall  be promptly  advised of  all purchase orders  for Shares  received by the
Distributor. Any order may be rejected by a Fund; provided, however, that a Fund
will not arbitrarily or without reasonable cause refuse to accept orders for the
purchase of Shares. The Distributor will confirm orders upon their receipt,  and
each  Fund (or its agent) upon receipt of payment therefor and instructions will
deliver share  certificates  for  such  Shares or  a  statement  confirming  the
issuance of Shares. Payment shall be made to the Fund in New York Clearing House
funds.  The Distributor agrees to cause such payment and such instructions to be
delivered promptly to the Fund (or its agent).
 
    (e) With respect to Shares sold  by any Selected Dealer, the Distributor  is
authorized to direct each Fund's transfer agent to receive instructions directly
from  the Selected  Dealer on  behalf of the  Distributor as  to registration of
Shares in the names of investors and  to confirm issuance of the Shares to  such
investors.  The Distributor is also authorized to instruct the transfer agent to
receive payment directly from the Selected Dealer on behalf of the  Distributor,
for  prompt transmittal to each  Fund's custodian, of the  purchase price of the
Shares. In such event the Distributor shall obtain from the Selected Dealer  and
maintain a record of such registration instructions and payments.
 
    SECTION 4.  REPURCHASE OR REDEMPTION OF SHARES.
 
    (a)  Any of the outstanding Shares of  a Fund may be tendered for redemption
at any time, and each Fund agrees to redeem its Shares so tendered in accordance
with the applicable provisions set forth in its Prospectus. The price to be paid
to redeem the Shares  shall be equal  to the net asset  value determined as  set
forth  in the Prospectus  less, in the case  of a Fund  whose Shares are offered
with a contingent deferred sales charge ("CDSC"), any applicable CDSC. Upon  any
redemption of Shares the Fund shall pay the total amount of the redemption price
in New York Clearing House funds in accordance with applicable provisions of the
Prospectus.
 
    (b)  In the case of  a Fund whose Shares are  offered with a front-end sales
charge, the redemption by a  Fund of any of its  Shares purchased by or  through
the Distributor will not affect the applicable front-end sales charge secured by
the  Distributor or  any Selected  Dealer in  the course  of the  original sale,
except that if any Shares are tendered for redemption within seven business days
after the date of the  confirmation of the original  purchase, the right to  the
applicable  front-end sales charge shall be forfeited by the Distributor and the
Selected Dealer which sold such Shares.
 
    (c) In the case of a Fund whose Shares are offered with a CDSC, the proceeds
of any redemption  of Shares  shall be  paid by each  Fund as  follows: (i)  any
applicable  CDSC shall be paid to the Distributor or to the Selected Dealer, or,
when applicable,  pursuant to  the  Rules of  the  Association of  the  National
Association  of Securities Dealers, Inc. ("NASD"), retained by the Fund and (ii)
the balance  shall  be paid  to  the redeeming  shareholders,  in each  case  in
accordance  with applicable  provisions of its  Prospectus in  New York Clearing
House funds. The Distributor is authorized to  direct a Fund to pay directly  to
the  Selected Dealer any CDSC payable by a Fund to the Distributor in respect of
Shares sold by the Selected Dealer to the redeeming shareholders.
 
    (d) The Distributor  is authorized,  as agent  for the  Fund, to  repurchase
Shares,  represented by a share certificate which  is delivered to any office of
the Distributor  in accordance  with  applicable provisions  set forth  in  each
Fund's Prospectus. The Distributor shall promptly transmit to the transfer agent
of  the Fund for  redemption all Shares  so delivered. The  Distributor shall be
responsible for the accuracy of instructions transmitted to the Fund's  transfer
agent in connection with all such repurchases.
 
    (e)  The Distributor  is authorized, as  agent for each  Fund, to repurchase
Shares held  in  a  shareholder's  account  with  a  Fund  for  which  no  share
certificate   has   been   issued,   upon   the   telephonic   request   of  the
 
                                       2
<PAGE>
shareholders, or at  the discretion  of the Distributor.  The Distributor  shall
promptly  transmit to the transfer  agent of the Fund,  for redemption, all such
orders for repurchase of Shares. Payment for Shares repurchased may be made by a
Fund to the  Distributor for  the account  of the  shareholder. The  Distributor
shall  be responsible for the accuracy of instructions transmitted to the Fund's
transfer agent in connection with all such repurchases.
 
    (f) Redemption of its Shares or payment by a Fund may be suspended at  times
when  the New York  Stock Exchange is  closed, when trading  on said Exchange is
restricted, when an emergency exists as a result of which disposal by a Fund  of
securities  owned by it  is not reasonably  practicable or it  is not reasonably
practicable for a  Fund fairly  to determine  the value  of its  net assets,  or
during any other period when the SEC, by order, so permits.
 
    (g)  With respect to its Shares tendered for redemption or repurchase by any
Selected Dealer on  behalf of its  customers, the Distributor  is authorized  to
instruct  the  transfer agent  of  a Fund  to  accept orders  for  redemption or
repurchase directly from the Selected Dealer on behalf of the Distributor and to
instruct the  Fund to  transmit payments  for such  redemptions and  repurchases
directly  to the Selected Dealer on behalf of the Distributor for the account of
the shareholder.  The Distributor  shall obtain  from the  Selected Dealer,  and
shall  maintain, a record of such  orders. The Distributor is further authorized
to obtain from the Fund, and shall  maintain, a record of payment made  directly
to the Selected Dealer on behalf of the Distributor.
 
    SECTION 5.  DUTIES OF THE FUND.
 
    (a)  Each Fund shall  furnish to the Distributor  copies of all information,
financial statements  and  other papers  which  the Distributor  may  reasonably
request for use in connection with the distribution of its Shares, including one
certified  copy, upon  request by the  Distributor, of  all financial statements
prepared by the Fund and examined  by independent accountants. Each Fund  shall,
at the expense of the Distributor, make available to the Distributor such number
of copies of its Prospectus as the Distributor shall reasonably request.
 
    (b)  Each Fund shall take,  from time to time,  but subject to the necessary
approval of its  shareholders, all  necessary action to  fix the  number of  its
authorized  Shares and to  register Shares under  the 1933 Act,  to the end that
there will  be  available  for sale  such  number  of Shares  as  investors  may
reasonably be expected to purchase.
 
    (c)  Each Fund  shall use  its best efforts  to pay  the filing  fees for an
appropriate number of its Shares  to be sold under  the securities laws of  such
states  as the Distributor and  the Fund may approve.  Any qualification to sell
its Shares in a state may be withheld, terminated or withdrawn by a Fund at  any
time  in its discretion.  As provided in  Section 8(c) hereof,  such filing fees
shall be paid  by the Fund.  The Distributor shall  furnish any information  and
other  material relating to its  affairs and activities as  may be required by a
Fund in connection with the sale of its Shares in any state.
 
    (d) Each  Fund  shall,  at  the expense  of  the  Distributor,  furnish,  in
reasonable  quantities upon request by the Distributor, copies of its annual and
interim reports.
 
    SECTION 6.  DUTIES OF THE DISTRIBUTOR.
 
    (a) The Distributor shall sell shares of each Fund through DWR and may  sell
shares  through other  securities dealers  and its  own Account  Executives, and
shall devote reasonable  time and  effort to promote  sales of  the Shares,  but
shall  not be obligated to  sell any specific number  of Shares. The services of
the Distributor  hereunder are  not  exclusive and  it  is understood  that  the
Distributor  may act  as principal  underwriter for  other registered investment
companies, so  long as  the  performance of  its  obligations hereunder  is  not
impaired  thereby. It is  also understood that  Selected Dealers, including DWR,
may also sell shares for other registered investment companies.
 
    (b)  Neither  the  Distributor  nor  any  Selected  Dealer  shall  give  any
information  or  make any  representations, other  than  those contained  in the
Registration  Statement  or   related  Prospectus  and   any  sales   literature
specifically approved by the appropriate Fund.
 
                                       3
<PAGE>
    (c)  The  Distributor agrees  that  it will  at  all times  comply  with the
applicable terms and limitations of the Rules of the Association of the NASD.
 
    SECTION 7.  SELECTED DEALERS AGREEMENTS.
 
    (a) The  Distributor shall  have the  right to  enter into  selected  dealer
agreements  with Selected Dealers  for the sale of  Shares. In making agreements
with Selected Dealers, the  Distributor shall act only  as principal and not  as
agent  for a Fund. Shares  sold to Selected Dealers shall  be for resale by such
dealers only at  the public  offering price set  forth in  the Prospectus.  With
respect to Funds whose Shares are offered with a front-end sales charge, in such
agreement  the  Distributor shall  have  the right  to  fix the  portion  of the
applicable front-end  sales  charge  which  may be  allocated  to  the  Selected
Dealers.
 
    (b)  Within the United  States, the Distributor shall  offer and sell Shares
only to Selected Dealers that are members in good standing of the NASD.
 
    (c) The Distributor shall adopt and  follow procedures, as approved by  each
Fund,  for the  confirmation of  sales of its  Shares to  investors and Selected
Dealers, the collection of amounts payable by investors and Selected Dealers  on
such  sales, and the cancellation of unsettled transactions, as may be necessary
to comply with the requirements of the NASD, as such requirements may from  time
to time exist.
 
    SECTION 8.  PAYMENT OF EXPENSES.
 
    (a)  Each Fund shall bear all costs and expenses of the Fund, including fees
and disbursements of legal counsel  including counsel to the  Directors/Trustees
of  each Fund who are not interested persons (as defined in the 1940 Act) of the
Fund or the  Distributor, and  independent accountants, in  connection with  the
preparation  and filing of any required Registration Statements and Prospectuses
and all  amendments  and supplements  thereto,  and the  expense  of  preparing,
printing,  mailing  and otherwise  distributing  prospectuses and  statements of
additional  information,  annual  or  interim  reports  or  proxy  materials  to
shareholders.
 
    (b)  The Distributor  shall bear all  expenses incurred by  it in connection
with its duties  and activities under  this Agreement including  the payment  to
Selected  Dealers of any sales commissions,  service fees and other expenses for
sales of a Fund's  Shares (except such expenses  as are specifically  undertaken
herein  by a  Fund) incurred  or paid  by Selected  Dealers, including  DWR. The
Distributor shall  bear  the  costs  and expenses  of  preparing,  printing  and
distributing  any  supplementary sales  literature  used by  the  Distributor or
furnished by it for use by Selected  Dealers in connection with the offering  of
the  Shares for  sale. Any expenses  of advertising incurred  in connection with
such offering will also be the  obligation of the Distributor. It is  understood
and agreed that, so long as a Fund's Plan of Distribution pursuant to Rule 12b-1
under  the  1940  Act ("Rule  12b-1  Plan")  continues in  effect,  any expenses
incurred by the Distributor hereunder may  be paid in accordance with the  terms
of such Rule 12b-1 Plan.
 
    (c)  Each Fund shall pay the filing  fees, and, if necessary or advisable in
connection therewith, bear  the cost and  expense of qualifying  each Fund as  a
broker  or dealer, in such states of the United States or other jurisdictions as
shall be  selected by  the Fund  and the  Distributor pursuant  to Section  5(c)
hereof  and the cost and  expenses payable to each  such state for continuing to
offer Shares  therein  until the  Fund  decides to  discontinue  selling  Shares
pursuant to Section 5(c) hereof.
 
    SECTION 9.  INDEMNIFICATION.
 
    (a)  Each Fund  shall indemnify and  hold harmless the  Distributor and each
person, if any, who controls the Distributor against any loss, liability, claim,
damage or expense (including the  reasonable cost of investigating or  defending
any  alleged loss,  liability, claim, damage  or expense  and reasonable counsel
fees incurred in connection therewith) arising by reason of any person acquiring
any Shares, which may be based upon the 1933 Act, or on any other statute or  at
common  law, on the ground that the Registration Statement or related Prospectus
and Statement  of Additional  Information,  as from  time  to time  amended  and
supplemented,  or  the annual  or  interim reports  to  shareholders of  a Fund,
includes an untrue statement  of a material  fact or omits  to state a  material
fact  required to be stated therein or necessary in order to make the statements
therein not misleading, unless such statement  or omission was made in  reliance
upon, and in
 
                                       4
<PAGE>
conformity with, information furnished to the Fund in connection therewith by or
on  behalf of  the Distributor; provided,  however, that  in no case  (i) is the
indemnity of a Fund in favor of the Distributor and any such controlling persons
to be deemed to protect the Distributor or any such controlling persons  thereof
against any liability to a Fund or its security holders to which the Distributor
or  any such controlling persons would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence  in the performance of its duties  or
by  reason  of  reckless disregard  of  its  obligations and  duties  under this
Agreement; or  (ii)  is  a Fund  to  be  liable under  its  indemnity  agreement
contained  in  this  paragraph  with  respect  to  any  claim  made  against the
Distributor or any such controlling persons, unless the Distributor or any  such
controlling persons, as the case may be, shall have notified the Fund in writing
within  a reasonable time after the summons  or other first legal process giving
information of  the  nature  of  the  claim shall  have  been  served  upon  the
Distributor  or  uch  controlling  persons (or  after  the  Distributor  or such
controlling persons shall have received notice of such service on any designated
agent), but failure to notify  the Fund of any such  claim shall not relieve  it
from  any liability which it may have to  the person against whom such action is
brought otherwise than on account of  its indemnity agreement contained in  this
paragraph.  Each Fund will be entitled to  participate at its own expense in the
defense, or, if it so elects, to assume the defense, of any such suit brought to
enforce any such liability,  but if a  Fund elects to  assume the defense,  such
defense  shall be  conducted by  counsel chosen  by it  and satisfactory  to the
Distributor or such controlling  person or persons,  defendant or defendants  in
the  suit. In the event the  Fund elects to assume the  defense of any such suit
and retain such counsel, the Distributor or such controlling person or  persons,
defendant  or defendants in  the suit, shall  bear the fees  and expenses of any
additional counsel retained by  them, but, in  case the Fund  does not elect  to
assume  the defense of any such suit,  it will reimburse the Distributor or such
controlling person or  persons, defendant  or defendants  in the  suit, for  the
reasonable  fees and expenses of  any counsel retained by  them. Each Fund shall
promptly notify  the  Distributor  of  the commencement  of  any  litigation  or
proceedings  against  it  or  any  of  its  officers  or  Directors/Trustees  in
connection with the issuance or sale of the Shares.
 
    (b)  (i)  The Distributor shall  indemnify and hold  harmless each Fund  and
each  of  its Directors/ Trustees and  officers  and each  person, if  any, who
controls the  Fund  against  any  loss, liability,  claim,  damage,  or  expense
described in the indemnity contained in subsection (a) of this Section, but only
with respect to statements or omissions made in reliance upon, and in conformity
with,  information  furnished  to a  Fund  in writing  by  or on  behalf  of the
Distributor for use  in connection  with the Registration  Statement or  related
Prospectus  and  Statement  of  Additional Information,  as  from  time  to time
amended, or the annual or interim reports to shareholders.
 
        (ii) The Distributor  shall indemnify  and hold harmless  each Fund  and
each  Fund's  transfer agent,  individually and  in its  capacity as  the Fund's
transfer agent, from and against any claims, damages and liabilities which arise
as a result of actions taken pursuant to instructions from, or on behalf of, the
Distributor to: (1) redeem  all or a  part of shareholder  accounts in the  Fund
pursuant  to Section 4(g) hereof and pay the proceeds to, or as directed by, the
Distributor for the account  of each shareholder whose  Shares are so  redeemed;
and  (2) register Shares in the names of investors, confirm the issuance thereof
and receive payment therefor pursuant to Section 3(e) hereof.
 
       (iii) In case any action shall be brought against a Fund or any person so
indemnified by this  Section 9(b) in  respect of which  indemnity may be  sought
against  the Distributor, the Distributor shall have the rights and duties given
to a Fund, and the Fund and each person so indemnified shall have the rights and
duties given to  the Distributor, by  the provisions of  subsection (a) of  this
Section 9.
 
    (c)  If the indemnification provided for in this Section 9 is unavailable or
insufficient to hold harmless an indemnified  party under subsection (a) or  (b)
above  in respect  of any losses,  claims, damages, liabilities  or expenses (or
actions in respect thereof)  referred to herein,  then each indemnifiying  party
shall  contribute to the amount  paid or payable by  such indemnified party as a
result of such losses, claims, damages,  liabilities or expenses (or actions  in
respect  thereof) in such  proportion as is appropriate  to reflect the relative
benefits received by a  Fund on the  one hand and the  Distributor on the  other
from  the offering of  the Shares. If,  however, the allocation  provided by the
immediately preceding sentence  is not  permitted by applicable  law, then  each
indemnifying  party  shall contribute  to such  amount paid  or payable  by such
indemnified party in
 
                                       5
<PAGE>
such proportion as is appropriate to reflect not only such relative benefits but
also the relative fault  of a Fund on  the one hand and  the Distributor on  the
other  in connection  with the  statements or  omissions which  resulted in such
losses,  claims,  damages,  liabilities  or  expenses  (or  actions  in  respect
thereof),  as well as any other  relevant equitable considerations. The relative
benefits received by a  Fund on the  one hand and the  Distributor on the  other
shall  be deemed to be in the same proportion as the total net proceeds from the
offering (before deducting  expenses) received  by the  Fund bear  to the  total
compensation  received by  the Distributor,  in each  case as  set forth  in the
Prospectus. The relative fault shall be determined by reference to, among  other
things, whether the untrue or alleged untrue statement of a material fact or the
omission  or alleged  omission to state  a material fact  relates to information
supplied by  a  Fund  or  the Distributor  and  the  parties'  relative  intent,
knowledge,  access to  information and  opportunity to  correct or  prevent such
statement or omission. Each Fund and the Distributor agree that it would not  be
just  and equitable if contribution were determined by pro rata allocation or by
any other method of  allocation which does not  take into account the  equitable
considerations  referred to above. The amount  paid or payable by an indemnified
party as a result  of the losses, claims,  damages, liabilities or expenses  (or
actions  in respect thereof)  referred to above  shall be deemed  to include any
legal or  other  expenses  reasonably  incurred by  such  indemnified  party  in
connection  with investigating or defending  any such claim. Notwithstanding the
provisions of this  subsection (c),  the Distributor  shall not  be required  to
contribute  any amount in excess of the amount by which the total price at which
the Shares distributed by it  to the public were  offered to the public  exceeds
the  amount of any damages which it has otherwise been required to pay by reason
of such untrue or alleged untrue  statement or omission or alleged omission.  No
person  guilty of  fraudulent misrepresentation  (within the  meaning of Section
11(f) of the 1933 Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation.
 
    SECTION 10.   DURATION AND TERMINATION  OF THIS AGREEMENT.   This  Agreement
shall become effective with respect to a Fund as of the date first above written
and shall remain in force until April 30, 1998, and thereafter, but only so long
as  such continuance is specifically approved at least annually by (i) the Board
of Directors/Trustees  of  each Fund,  or  by the  vote  of a  majority  of  the
outstanding  voting securities of the Fund, cast in person or by proxy, and (ii)
a majority of those Directors/Trustees who are not parties to this Agreement  or
interested  persons  of  any such  party  and  who have  no  direct  or indirect
financial interest in  this Agreement  or in the  operation of  the Fund's  Rule
12b-1  Plan or  in any agreement  related thereto,  cast in person  at a meeting
called for the purpose of voting upon such approval.
 
    This Agreement may  be terminated  at any time  without the  payment of  any
penalty,   by  the   Directors/Trustees  of  a  Fund,   by  a  majority  of  the
Directors/Trustees of a Fund who are not interested persons of the Fund and  who
have no direct or indirect financial interest in this Agreement, or by vote of a
majority  of the outstanding voting securities of a Fund, or by the Distributor,
on sixty  days'  written  notice  to  the  other  party.  This  Agreement  shall
automatically terminate in the event of its assignment.
 
    The  terms  "vote  of  a majority  of  the  outstanding  voting securities,"
"assignment" and "interested person,"  when used in  this Agreement, shall  have
the respective meanings specified in the 1940 Act.
 
    SECTION 11.  AMENDMENTS OF THIS AGREEMENT.  This Agreement may be amended by
the  parties  only  if  such  amendment  is  specifically  approved  by  (i) the
Directors/Trustees of a Fund, or by the vote of a majority of outstanding voting
securities of a Fund, and (ii) a majority of those Directors/Trustees of a  Fund
who  are not parties to  this Agreement or interested  persons of any such party
and who have no direct  or indirect financial interest  in this Agreement or  in
any Agreement related to the Fund's Rule 12b-1 Plan, cast in person at a meeting
called for the purpose of voting on such approval.
 
    SECTION  12.   ADDITIONAL FUNDS.   If  at any  time another  Fund desires to
appoint the Distributor as its principal underwriter and distributor under  this
Agreement,  it shall  notify the Distributor  in writing. If  the Distributor is
willing to serve as the Fund's principal underwriter and distributor under  this
Agreement,  it shall notify the Fund in writing, whereupon such other Fund shall
become a Fund hereunder.
 
                                       6
<PAGE>
    SECTION 13.  GOVERNING LAW.  This Agreement shall be construed in accordance
with the law of the State of New York and the applicable provisions of the  1940
Act.  To the extent the applicable  law of the State of  New York, or any of the
provisions herein, conflicts with the applicable provisions of the 1940 Act, the
latter shall control.
 
    SECTION 14.  PERSONAL LIABILITY.  With respect to any Fund that is organized
as an  unincorporated business  trust  under the  laws  of the  Commonwealth  of
Massachusetts,  its Declaration of the Trust  (each, a "Declaration") is on file
in the  office of  the  Secretary of  the  Commonwealth of  Massachusetts.  Each
Declaration  provides that the name of the Fund refers to the Trustees under the
Declaration collectively as Trustees, but not as individuals or personally;  and
no Trustee, shareholder, officer, employee or agent of any Fund shall be held to
any  personal liability, nor shall  resort be had to  their private property for
the satisfaction of any obligation or claim or otherwise, in connection with the
affairs of any Fund, but the Trust Estate only shall be liable.
 
    IN WITNESS  WHEREOF, the  parties hereto  have executed  and delivered  this
Agreement as of the day and year first written in New York, New York.

                               DEAN WITTER FUNDS

                             DISTRIBUTION AGREEMENT
 
    AGREEMENT made as of this 28th day of July, 1997 between each of the
open-end investment companies to which Dean Witter InterCapital Inc. acts as
investment manager, that are listed on Schedule A, as may be amended from time
to time (each, a "Fund" and collectively, the "Funds"), and Dean Witter
Distributors Inc., a Delaware corporation (the "Distributor").
 
                              W I T N E S S E T H:
 
    WHEREAS, each Fund is registered as an open-end investment company under the
Investment Company Act of 1940, as amended (the "1940 Act"), and it is in the
interest of each Fund to offer its shares for sale continuously, and
 
    WHEREAS, each Fund and the Distributor wish to enter into an agreement with
each other with respect to the continuous offering of each Fund's transferable
shares, of $0.01 par value (the "Shares"), to commence on the date listed above,
in order to promote the growth of each Fund and facilitate the distribution of
its shares.
 
    NOW, THEREFORE, the parties agree as follows:
 
    SECTION 1.  APPOINTMENT OF THE DISTRIBUTOR.
 
    (a) Each Fund hereby appoints the Distributor as the principal underwriter
and distributor of the Fund to sell Shares to the public on the terms set forth
in this Agreement and that Fund's prospectus and the Distributor hereby accepts
such appointment and agrees to act hereunder. Each Fund, during the term of this
Agreement, shall sell Shares to the Distributor upon the terms and conditions
set forth herein.
 
    (b) The Distributor agrees to purchase Shares, as principal for its own
account, from each Fund and to sell Shares as principal to investors, and
securities dealers, including Dean Witter Reynolds Inc. ("DWR"), an affiliate of
the Distributor, upon the terms described herein and in that Fund's prospectus
(the "Prospectus") and statement of additional information included in the
Fund's registration statement (the "Registration Statement") most recently filed
from time to time with the Securities and Exchange Commission (the "SEC") and
effective under the Securities Act of 1933, as amended (the "1933 Act"), and the
1940 Act or as the Prospectus may be otherwise amended or supplemented and filed
with the SEC pursuant to Rule 497 under the 1933 Act.
 
    SECTION 2.  EXCLUSIVE NATURE OF DUTIES.  The Distributor shall be the
exclusive principal underwriter and distributor of each Fund, except that the
exclusive rights granted to the Distributor to sell the Shares shall not apply
to Shares issued by each Fund: (i) in connection with the merger or
consolidation of any other investment company or personal holding company with
the Fund or the acquisition by purchase or otherwise of all (or substantially
all) the assets or the outstanding shares of any such company by the Fund; (ii)
pursuant to reinvestment of dividends or capital gains distributions; or (iii)
pursuant to the reinstatement privilege afforded redeeming shareholders.
 
    SECTION 3.  PURCHASE OF SHARES FROM EACH FUND.  The Shares are offered in
four classes (each, a "Class"), as described in the Prospectus, as amended or
supplemented from time to time.
 
    (a) The Distributor shall have the right to buy from each Fund the Shares of
the particular class needed, but not more than the Shares needed (except for
clerical errors in transmission), to fill unconditional orders for Shares of the
applicable class placed with the Distributor by investors or securities dealers.
The price which the Distributor shall pay for the Shares so purchased from the
Fund shall be the net asset value, determined as set forth in the Prospectus,
used in determining the public offering price on which such orders were based.
 
    (b) The Shares are to be resold by the Distributor at the public offering
price of Shares of the applicable class as set forth in the Prospectus, to
investors or to securities dealers, including DWR, who
 
                                       1
<PAGE>
have entered into selected dealer agreements with the Distributor upon the terms
and conditions set forth in Section 7 hereof ("Selected Dealers").
 
    (c) Each Fund shall have the right to suspend the sale of the Shares at
times when redemption is suspended pursuant to the conditions set forth in
Section 4(f) hereof. Each Fund shall also have the right to suspend the sale of
the Shares if trading on the New York Stock Exchange shall have been suspended,
if a banking moratorium shall have been declared by federal or New York
authorities, or if there shall have been some other extraordinary event which,
in the judgment of a Fund, makes it impracticable to sell its Shares.
 
    (d) Each Fund, or any agent of a Fund designated in writing by the Fund,
shall be promptly advised of all purchase orders for Shares received by the
Distributor. Any order may be rejected by a Fund; provided, however, that a Fund
will not arbitrarily or without reasonable cause refuse to accept orders for the
purchase of Shares. The Distributor will confirm orders upon their receipt, and
each Fund (or its agent) upon receipt of payment therefor and instructions will
deliver share certificates for such Shares or a statement confirming the
issuance of Shares. Payment shall be made to the Fund in New York Clearing House
funds. The Distributor agrees to cause such payment and such instructions to be
delivered promptly to the Fund (or its agent).
 
    (e) With respect to Shares sold by any Selected Dealer, the Distributor is
authorized to direct each Fund's transfer agent to receive instructions directly
from the Selected Dealer on behalf of the Distributor as to registration of
Shares in the names of investors and to confirm issuance of the Shares to such
investors. The Distributor is also authorized to instruct the transfer agent to
receive payment directly from the Selected Dealer on behalf of the Distributor,
for prompt transmittal to each Fund's custodian, of the purchase price of the
Shares. In such event the Distributor shall obtain from the Selected Dealer and
maintain a record of such registration instructions and payments.
 
    SECTION 4.  REPURCHASE OR REDEMPTION OF SHARES.
 
    (a) Any of the outstanding Shares of a Fund may be tendered for redemption
at any time, and each Fund agrees to redeem its Shares so tendered in accordance
with the applicable provisions set forth in its Prospectus. The price to be paid
to redeem the Shares shall be equal to the net asset value determined as set
forth in the Prospectus less any applicable contingent deferred sales charge
("CDSC"). Upon any redemption of Shares the Fund shall pay the total amount of
the redemption price in New York Clearing House funds in accordance with
applicable provisions of the Prospectus.
 
    (b) The redemption by a Fund of any of its Class A Shares purchased by or
through the Distributor will not affect the applicable front-end sales charge
secured by the Distributor or any Selected Dealer in the course of the original
sale, except that if any Class A Shares are tendered for redemption within seven
business days after the date of the confirmation of the original purchase, the
right to the applicable front-end sales charge shall be forfeited by the
Distributor and the Selected Dealer which sold such Shares.
 
    (c) The proceeds of any redemption of Class A, Class B or Class C Shares
shall be paid by each Fund as follows: (i) any applicable CDSC shall be paid to
the Distributor or to the Selected Dealer, or, when applicable, pursuant to the
Rules of the Association of the National Association of Securities Dealers, Inc.
("NASD"), retained by the Fund and (ii) the balance shall be paid to the
redeeming shareholders, in each case in accordance with applicable provisions of
its Prospectus in New York Clearing House funds. The Distributor is authorized
to direct a Fund to pay directly to the Selected Dealer any CDSC payable by a
Fund to the Distributor in respect of Class A, Class B, or Class C Shares sold
by the Selected Dealer to the redeeming shareholders.
 
    (d) The Distributor is authorized, as agent for the Fund, to repurchase
Shares, represented by a share certificate which is delivered to any office of
the Distributor in accordance with applicable provisions set forth in each
Fund's Prospectus. The Distributor shall promptly transmit to the transfer agent
of the Fund for redemption all Shares so delivered. The Distributor shall be
responsible for the accuracy of instructions transmitted to the Fund's transfer
agent in connection with all such repurchases.
 
                                       2
<PAGE>
    (e) The Distributor is authorized, as agent for each Fund, to repurchase
Shares held in a shareholder's account with a Fund for which no share
certificate has been issued, upon the telephonic request of the shareholders, or
at the discretion of the Distributor. The Distributor shall promptly transmit to
the transfer agent of the Fund, for redemption, all such orders for repurchase
of Shares. Payment for Shares repurchased may be made by a Fund to the
Distributor for the account of the shareholder. The Distributor shall be
responsible for the accuracy of instructions transmitted to the Fund's transfer
agent in connection with all such repurchases.
 
    (f) Redemption of its Shares or payment by a Fund may be suspended at times
when the New York Stock Exchange is closed, when trading on said Exchange is
restricted, when an emergency exists as a result of which disposal by a Fund of
securities owned by it is not reasonably practicable or it is not reasonably
practicable for a Fund fairly to determine the value of its net assets, or
during any other period when the SEC, by order, so permits.
 
    (g) With respect to its Shares tendered for redemption or repurchase by any
Selected Dealer on behalf of its customers, the Distributor is authorized to
instruct the transfer agent of a Fund to accept orders for redemption or
repurchase directly from the Selected Dealer on behalf of the Distributor and to
instruct the Fund to transmit payments for such redemptions and repurchases
directly to the Selected Dealer on behalf of the Distributor for the account of
the shareholder. The Distributor shall obtain from the Selected Dealer, and
shall maintain, a record of such orders. The Distributor is further authorized
to obtain from the Fund, and shall maintain, a record of payment made directly
to the Selected Dealer on behalf of the Distributor.
 
    SECTION 5.  DUTIES OF THE FUND.
 
    (a) Each Fund shall furnish to the Distributor copies of all information,
financial statements and other papers which the Distributor may reasonably
request for use in connection with the distribution of its Shares, including one
certified copy, upon request by the Distributor, of all financial statements
prepared by the Fund and examined by independent accountants. Each Fund shall,
at the expense of the Distributor, make available to the Distributor such number
of copies of its Prospectus as the Distributor shall reasonably request.
 
    (b) Each Fund shall take, from time to time, but subject to the necessary
approval of its shareholders, all necessary action to fix the number of its
authorized Shares and to register Shares under the 1933 Act, to the end that
there will be available for sale such number of Shares as investors may
reasonably be expected to purchase.
 
    (c) Each Fund shall use its best efforts to pay the filing fees for an
appropriate number of its Shares to be sold under the securities laws of such
states as the Distributor and the Fund may approve. Any qualification to sell
its Shares in a state may be withheld, terminated or withdrawn by a Fund at any
time in its discretion. As provided in Section 8(c) hereof, such filing fees
shall be paid by the Fund. The Distributor shall furnish any information and
other material relating to its affairs and activities as may be required by a
Fund in connection with the sale of its Shares in any state.
 
    (d) Each Fund shall, at the expense of the Distributor, furnish, in
reasonable quantities upon request by the Distributor, copies of its annual and
interim reports.
 
    SECTION 6.  DUTIES OF THE DISTRIBUTOR.
 
    (a) The Distributor shall sell shares of each Fund through DWR and may sell
shares through other securities dealers and its own Account Executives, and
shall devote reasonable time and effort to promote sales of the Shares, but
shall not be obligated to sell any specific number of Shares. The services of
the Distributor hereunder are not exclusive and it is understood that the
Distributor may act as principal underwriter for other registered investment
companies, so long as the performance of its obligations hereunder is not
impaired thereby. It is also understood that Selected Dealers, including DWR,
may also sell shares for other registered investment companies.
 
                                       3
<PAGE>
    (b) Neither the Distributor nor any Selected Dealer shall give any
information or make any representations, other than those contained in the
Registration Statement or related Prospectus and any sales literature
specifically approved by the appropriate Fund.
 
    (c) The Distributor agrees that it will at all times comply with the
applicable terms and limitations of the Rules of the Association of the NASD.
 
    SECTION 7.  SELECTED DEALERS AGREEMENTS.
 
    (a) The Distributor shall have the right to enter into selected dealer
agreements with Selected Dealers for the sale of Shares. In making agreements
with Selected Dealers, the Distributor shall act only as principal and not as
agent for a Fund. Shares sold to Selected Dealers shall be for resale by such
dealers only at the public offering price set forth in the Prospectus. With
respect to Class A Shares, in such agreement the Distributor shall have the
right to fix the portion of the applicable front-end sales charge which may be
allocated to the Selected Dealers.
 
    (b) Within the United States, the Distributor shall offer and sell Shares
only to Selected Dealers that are members in good standing of the NASD.
 
    (c) The Distributor shall adopt and follow procedures, as approved by each
Fund, for the confirmation of sales of its Shares to investors and Selected
Dealers, the collection of amounts payable by investors and Selected Dealers on
such sales, and the cancellation of unsettled transactions, as may be necessary
to comply with the requirements of the NASD, as such requirements may from time
to time exist.
 
    SECTION 8.  PAYMENT OF EXPENSES.
 
    (a) Each Fund shall bear all costs and expenses of the Fund, including fees
and disbursements of legal counsel including counsel to the Directors/Trustees
of each Fund who are not interested persons (as defined in the 1940 Act) of the
Fund or the Distributor, and independent accountants, in connection with the
preparation and filing of any required Registration Statements and Prospectuses
and all amendments and supplements thereto, and the expense of preparing,
printing, mailing and otherwise distributing prospectuses and statements of
additional information, annual or interim reports or proxy materials to
shareholders.
 
    (b) The Distributor shall bear all expenses incurred by it in connection
with its duties and activities under this Agreement including the payment to
Selected Dealers of any sales commissions, service fees and other expenses for
sales of a Fund's Shares (except such expenses as are specifically undertaken
herein by a Fund) incurred or paid by Selected Dealers, including DWR. The
Distributor shall bear the costs and expenses of preparing, printing and
distributing any supplementary sales literature used by the Distributor or
furnished by it for use by Selected Dealers in connection with the offering of
the Shares for sale. Any expenses of advertising incurred in connection with
such offering will also be the obligation of the Distributor. It is understood
and agreed that, so long as a Fund's Plan of Distribution pursuant to Rule 12b-1
under the 1940 Act ("Rule 12b-1 Plan") continues in effect, any expenses
incurred by the Distributor hereunder may be paid in accordance with the terms
of such Rule 12b-1 Plan.
 
    (c) Each Fund shall pay the filing fees, and, if necessary or advisable in
connection therewith, bear the cost and expense of qualifying each Fund as a
broker or dealer, in such states of the United States or other jurisdictions as
shall be selected by the Fund and the Distributor pursuant to Section 5(c)
hereof and the cost and expenses payable to each such state for continuing to
offer Shares therein until the Fund decides to discontinue selling Shares
pursuant to Section 5(c) hereof.
 
    SECTION 9.  INDEMNIFICATION.
 
    (a) Each Fund shall indemnify and hold harmless the Distributor and each
person, if any, who controls the Distributor against any loss, liability, claim,
damage or expense (including the reasonable cost of investigating or defending
any alleged loss, liability, claim, damage or expense and reasonable counsel
fees incurred in connection therewith) arising by reason of any person acquiring
any Shares, which may be based upon the 1933 Act, or on any other statute or at
common law, on the ground that the Registration Statement or related Prospectus
and Statement of Additional Information, as from time to time amended
 
                                       4
<PAGE>
and supplemented, or the annual or interim reports to shareholders of a Fund,
includes an untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary in order to make the statements
therein not misleading, unless such statement or omission was made in reliance
upon, and in conformity with, information furnished to the Fund in connection
therewith by or on behalf of the Distributor; provided, however, that in no case
(i) is the indemnity of a Fund in favor of the Distributor and any such
controlling persons to be deemed to protect the Distributor or any such
controlling persons thereof against any liability to a Fund or its security
holders to which the Distributor or any such controlling persons would otherwise
be subject by reason of willful misfeasance, bad faith or gross negligence in
the performance of its duties or by reason of reckless disregard of its
obligations and duties under this Agreement; or (ii) is a Fund to be liable
under its indemnity agreement contained in this paragraph with respect to any
claim made against the Distributor or any such controlling persons, unless the
Distributor or any such controlling persons, as the case may be, shall have
notified the Fund in writing within a reasonable time after the summons or other
first legal process giving information of the nature of the claim shall have
been served upon the Distributor or uch controlling persons (or after the
Distributor or such controlling persons shall have received notice of such
service on any designated agent), but failure to notify the Fund of any such
claim shall not relieve it from any liability which it may have to the person
against whom such action is brought otherwise than on account of its indemnity
agreement contained in this paragraph. Each Fund will be entitled to participate
at its own expense in the defense, or, if it so elects, to assume the defense,
of any such suit brought to enforce any such liability, but if a Fund elects to
assume the defense, such defense shall be conducted by counsel chosen by it and
satisfactory to the Distributor or such controlling person or persons, defendant
or defendants in the suit. In the event the Fund elects to assume the defense of
any such suit and retain such counsel, the Distributor or such controlling
person or persons, defendant or defendants in the suit, shall bear the fees and
expenses of any additional counsel retained by them, but, in case the Fund does
not elect to assume the defense of any such suit, it will reimburse the
Distributor or such controlling person or persons, defendant or defendants in
the suit, for the reasonable fees and expenses of any counsel retained by them.
Each Fund shall promptly notify the Distributor of the commencement of any
litigation or proceedings against it or any of its officers or
Directors/Trustees in connection with the issuance or sale of the Shares.
 
    (b) (i) The Distributor shall indemnify and hold harmless each Fund and each
of its Directors/ Trustees and officers and each person, if any, who controls
the Fund against any loss, liability, claim, damage, or expense described in the
indemnity contained in subsection (a) of this Section, but only with respect to
statements or omissions made in reliance upon, and in conformity with,
information furnished to a Fund in writing by or on behalf of the Distributor
for use in connection with the Registration Statement or related Prospectus and
Statement of Additional Information, as from time to time amended, or the annual
or interim reports to shareholders.
 
        (ii) The Distributor shall indemnify and hold harmless each Fund and
each Fund's transfer agent, individually and in its capacity as the Fund's
transfer agent, from and against any claims, damages and liabilities which arise
as a result of actions taken pursuant to instructions from, or on behalf of, the
Distributor to: (1) redeem all or a part of shareholder accounts in the Fund
pursuant to Section 4(g) hereof and pay the proceeds to, or as directed by, the
Distributor for the account of each shareholder whose Shares are so redeemed;
and (2) register Shares in the names of investors, confirm the issuance thereof
and receive payment therefor pursuant to Section 3(e) hereof.
 
        (iii) In case any action shall be brought against a Fund or any person
so indemnified by this Section 9(b) in respect of which indemnity may be sought
against the Distributor, the Distributor shall have the rights and duties given
to a Fund, and the Fund and each person so indemnified shall have the rights and
duties given to the Distributor, by the provisions of subsection (a) of this
Section 9.
 
    (c) If the indemnification provided for in this Section 9 is unavailable or
insufficient to hold harmless an indemnified party under subsection (a) or (b)
above in respect of any losses, claims, damages, liabilities or expenses (or
actions in respect thereof) referred to herein, then each indemnifiying party
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages, liabilities or expenses (or actions in
respect thereof) in such proportion as is appropriate to reflect the relative
benefits received by a Fund on the one hand and the Distributor on the other
from the
 
                                       5
<PAGE>
offering of the Shares. If, however, the allocation provided by the immediately
preceding sentence is not permitted by applicable law, then each indemnifying
party shall contribute to such amount paid or payable by such indemnified party
in such proportion as is appropriate to reflect not only such relative benefits
but also the relative fault of a Fund on the one hand and the Distributor on the
other in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or expenses (or actions in respect
thereof), as well as any other relevant equitable considerations. The relative
benefits received by a Fund on the one hand and the Distributor on the other
shall be deemed to be in the same proportion as the total net proceeds from the
offering (before deducting expenses) received by the Fund bear to the total
compensation received by the Distributor, in each case as set forth in the
Prospectus. The relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by a Fund or the Distributor and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. Each Fund and the Distributor agree that it would not be
just and equitable ifcontribution were determined by pro rata allocation or by
any other method of allocation which does not take into account the equitable
considerations referred to above. The amount paid or payable by an indemnified
party as a result of the losses, claims, damages, liabilities or expenses (or
actions in respect thereof) referred to above shall be deemed to include any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such claim. Notwithstanding the
provisions of this subsection (c), the Distributor shall not be required to
contribute any amount in excess of the amount by which the total price at which
the Shares distributed by it to the public were offered to the public exceeds
the amount of any damages which it has otherwise been required to pay by reason
of such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the 1933 Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation.
 
    SECTION 10.  DURATION AND TERMINATION OF THIS AGREEMENT.  This Agreement
shall become effective with respect to a Fund as of the date first above written
and shall remain in force until April 30, 1998, and thereafter, but only so long
as such continuance is specifically approved at least annually by (i) the Board
of Directors/Trustees of each Fund, or by the vote of a majority of the
outstanding voting securities of the Fund, cast in person or by proxy, and (ii)
a majority of those Directors/Trustees who are not parties to this Agreement or
interested persons of any such party and who have no direct or indirect
financial interest in this Agreement or in the operation of the Fund's Rule
12b-1 Plan or in any agreement related thereto, cast in person at a meeting
called for the purpose of voting upon such approval.
 
    This Agreement may be terminated at any time without the payment of any
penalty, by the Directors/ Trustees of a Fund, by a majority of the
Directors/Trustees of a Fund who are not interested persons of the Fund and who
have no direct or indirect financial interest in this Agreement, or by vote of a
majority of the outstanding voting securities of a Fund, or by the Distributor,
on sixty days' written notice to the other party. This Agreement shall
automatically terminate in the event of its assignment.
 
    The terms "vote of a majority of the outstanding voting securities,"
"assignment" and "interested person," when used in this Agreement, shall have
the respective meanings specified in the 1940 Act.
 
    SECTION 11.  AMENDMENTS OF THIS AGREEMENT.  This Agreement may be amended by
the parties only if such amendment is specifically approved by (i) the
Directors/Trustees of a Fund, or by the vote of a majority of outstanding voting
securities of a Fund, and (ii) a majority of those Directors/Trustees of a Fund
who are not parties to this Agreement or interested persons of any such party
and who have no direct or indirect financial interest in this Agreement or in
any Agreement related to the Fund's Rule 12b-1 Plan, cast in person at a meeting
called for the purpose of voting on such approval.
 
    SECTION 12.  ADDITIONAL FUNDS.  If at any time another Fund desires to
appoint the Distributor as its principal underwriter and distributor under this
Agreement, it shall notify the Distributor in writing. If the Distributor is
willing to serve as the Fund's principal underwriter and distributor under this
Agreement, it shall notify the Fund in writing, whereupon such other Fund shall
become a Fund hereunder.
 
    SECTION 13.  GOVERNING LAW.  This Agreement shall be construed in accordance
with the law of the State of New York and the applicable provisions of the 1940
Act. To the extent the applicable law of the
 
                                       6
<PAGE>
State of New York, or any of the provisions herein, conflicts with the
applicable provisions of the 1940 Act, the latter shall control.
 
    SECTION 14.  PERSONAL LIABILITY.  With respect to any Fund that is organized
as an unincorporated business trust under the laws of the Commonwealth of
Massachusetts, its Declaration of the Trust (each, a "Declaration") is on file
in the office of the Secretary of the Commonwealth of Massachusetts. Each
Declaration provides that the name of the Fund refers to the Trustees under the
Declaration collectively as Trustees, but not as individuals or personally; and
no Trustee, shareholder, officer, employee or agent of any Fund shall be held to
any personal liability, nor shall resort be had to their private property for
the satisfaction of any obligation or claim or otherwise, in connection with the
affairs of any Fund, but the Trust Estate only shall be liable.
 
    IN WITNESS WHEREOF, the parties hereto have executed and delivered this
Agreement as of the day and year first written in New York, New York.

       AMENDED AND RESTATED PLAN OF DISTRIBUTION PURSUANT TO RULE 12b-1
                                      OF
                    DEAN WITTER WORLD WIDE INCOME TRUST

   WHEREAS, Dean Witter WORLD WIDE INCOME TRUST (the "Fund") is engaged in
business as an open-end management investment company and is registered as
such under the Investment Company Act of 1940, as amended (the "Act"); and

   WHEREAS, on October 26, 1995, the Fund most recently amended and restated a
Plan of Distribution pursuant to Rule 12b-1 under the Act which had initially
been adopted on February 1, 1989, and the Trustees then determined that there
was a reasonable likelihood that adoption of the Plan of Distribution, as
then amended and restated, would benefit the Fund and its shareholders; and

   WHEREAS, the Trustees believe that continuation of said Plan of
Distribution, as amended and restated herein, is reasonably likely to
continue to benefit the Fund and its shareholders; and

   WHEREAS, on February 1, 1989, the Fund and Dean Witter Reynolds Inc.
("DWR") entered into a Distribution Agreement pursuant to which the Fund
employed DWR as distributor of the Fund's shares; and

   WHEREAS, on January 4, 1993, the Fund and DWR substituted Dean Witter
Distributors Inc. (the "Distributor") in the place of DWR as distributor of
the Fund's shares; and

   WHEREAS, the Fund, DWR and the Distributor intend that DWR will continue
to promote the sale of Fund shares and provide personal services to Fund
shareholders with respect to their holdings of Fund shares; and

   WHEREAS, the Fund and the Distributor entered into a separate Distribution
Agreement dated as of July 28, 1997 (which superseded a Distribution
Agreement dated May 31, 1997, which Agreement in turn superseded an Agreement
dated June 30, 1993), pursuant to which the Fund has employed the Distributor
in such capacity during the continuous offering of shares of the Fund.

   NOW, THEREFORE, the Fund hereby amends the Plan of Distribution previously
adopted and amended and restated, and the Distributor hereby agrees to the
terms of said Plan of Distribution (the "Plan"), as amended herein, in
accordance with Rule 12b-1 under the Act on the following terms and
conditions with respect to the Class A, Class B and Class C shares of the
Fund:

   1(a)(i). With respect to Class A and Class C shares of the Fund, the
Distributor hereby undertakes to directly bear all costs of rendering the
services to be performed by it under this Plan and under the Distribution
Agreement, except for those specific expenses that the Trustees determine to
reimburse as hereinafter set forth.

   1(a)(ii). The Fund is hereby authorized to reimburse the Distributor, DWR,
its affiliates and other broker-dealers for distribution expenses incurred by
them specifically on behalf of Class A and Class C shares of the Fund.
Reimbursement will be made through payments at the end of each month. The
amount of each monthly payment may in no event exceed an amount equal to a
payment at the annual rate of 0.25%, in the case of Class A, and 0.85%, in the
case of Class C, of the average net assets of the respective Class during the
month. 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 Trustees who are not "interested persons" of the Fund, as defined in the
Act. 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 the
quarterly determinations of the amounts that may be expended by the Fund, the
Distributor shall provide, and the Trustees shall review, a quarterly budget
of projected distribution expenses to be incurred by the Distributor, DWR,
its affiliates or other broker-dealers on behalf of the Fund together with a
report explaining the purposes and anticipated benefits of incurring

                                1

<PAGE>

such expenses. The Trustees shall determine the particular expenses, and the
portion thereof that may be borne by the Fund, and in making such
determination shall consider the scope of the Distributor's commitment to
promoting the distribution of the Fund's Class A and Class C shares directly
or through DWR, its affiliates or other broker-dealers.

   1(a)(iii). If, as of the end of any calendar year, the actual expenses
incurred by the Distributor, DWR, its affiliates and other broker-dealers on
behalf of Class A or Class C shares of the Fund (including accrued expenses
and amounts reserved for incentive compensation and bonuses) are less than
the amount of payments made by such Class pursuant to this Plan, the
Distributor shall promptly make appropriate reimbursement to the appropriate
Class. If, however, as of the end of any calendar year, the actual expenses
(other than expenses representing a gross sales credit) of the Distributor,
DWR, its affiliates and other broker-dealers are greater than the amount of
payments made by Class A or Class C shares of the Fund pursuant to this Plan,
such Class will not reimburse the Distributor, DWR, its affiliates or other
broker-dealers for such expenses through payments accrued pursuant to this
Plan in the subsequent fiscal year. Expenses representing a gross sales
credit may be reimbursed in the subsequent calendar year.

   1(b). With respect to Class B shares of the Fund, the Fund shall pay to
the Distributor, as the distributor of securities of which the Fund is the
issuer, compensation for distribution of its Class B shares at the rate of
the lesser of (i) 0.85% per annum of the average daily aggregate sales of the
Fund's Class B shares since the Fund's inception (not including reinvestment
of dividends and capital gains distributions from the Fund) 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 deferred sales charge has been
imposed or upon which such charge has been waived, or (ii) 0.85% per annum of
the average daily net assets of Class B. Such compensation shall be
calculated and accrued daily and paid monthly or at such other intervals as
the Trustees shall determine.

   The Distributor may direct that all or any part of the amounts receivable
by it under this Plan be paid directly to DWR, its affiliates or other
broker-dealers who provide distribution and shareholder services. All
payments made hereunder pursuant to the Plan shall be in accordance with the
terms and limitations of the Rules of the Association of the National
Association of Securities Dealers, Inc.

   2. With respect to expenses incurred by each Class, the amount set forth
in paragraph 1 of this Plan shall be paid for services of the Distributor,
DWR its affiliates and other broker-dealers it may select in connection with
the distribution of the Fund's shares, including personal services to
shareholders with respect to their holdings of Fund shares, and may be spend
by the Distributor, DWR, its affiliates and such broker-dealers on any
activities or expenses related to the distribution of the Fund's shares or
services to shareholders, including, but not limited to: compensation to, and
expenses of, account executives or other employees of the Distributor, DWR,
its affiliates or other broker-dealers; overhead and other branch office
distribution-related expenses and telephone expenses of persons who engage in
or support distribution of shares or who provide personal services to
shareholders; printing of prospectuses and reports for other than existing
shareholders; preparation, printing and distribution of sales literature and
advertising materials and, with respect to Class B, opportunity costs in
incurring the foregoing expenses (which may be calculated as a carrying
charge on the excess of the distribution expenses incurred by the
Distributor, DWR, its affiliates or other broker-dealers over distribution
revenues received by them, such excess being hereinafter referred to as
"carryover expenses"). The overhead and other branch office
distribution-related expenses referred to in this paragraph 2 may include:
(a) the expenses operating the branch offices of the Distributor or other
broker-dealers, including DWR, in connection with the sale of the 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. Payments may also be made with respect to 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, provided that, with respect to Class B, carryover expenses as 
a percentage of Fund assets will not be materially increased there by. It is 

                                2

<PAGE>

contemplated that, with respect to Class A shares, the entire fee set forth 
in paragraph 1(a) will be characterized as a service fee within the meaning 
of the National Association of Securities Dealers, Inc. guidelines and that, 
with respect to Class B Shares, payments at the annual rate of 0.20% will be 
so characterized and that, with respect to Class C shares, payments at the 
annual rate of 0.25% will be so characterized.

   3. This Plan, as amended and restated, shall not take effect with respect
to any particular Class until it has been approved, together with any related
agreements, by votes of a majority of the Board of Trustees of the Fund and
of the Trustees who are not "interested persons" of the Fund (as defined in
the Act) and have no direct financial interest in the operation of this Plan
or any agreements related to it (the "Rule 12b-1 Trustees"), cast in person
at a meeting (or meetings) called for the purpose of voting on this Plan and
such related agreements.

   4. This Plan shall continue in effect with respect to each Class until
April 30, 1998, and from year to year thereafter, provided such continuance
is specifically approved at least annually in the manner provided for
approval of this Plan in paragraph 3 hereof.

   5. The Distributor shall provide to the Trustees of the Fund and the
Trustees shall review, at least quarterly, a written report of the amounts so
expended and the purposes for which such expenditures were made. In this
regard, the Trustees shall request the Distributor to specify such items of
expenses as the Trustees deem appropriate. The Trustees shall consider such
items as they deem relevant in making the determinations required by
paragraph 4 hereof.

   6. This Plan may be terminated at any time with respect to a Class by vote
of a majority of the Rule 12b-1 Trustees, or by vote of a majority of the
outstanding voting securities of the Fund. The Plan may remain in effect with
the respect to a particular Class even if the Plan has been terminated in
accordance with this paragraph 6 with respect to any other Class. In the
event of any such termination or in the event of nonrenewal, the Fund shall
have no obligation to pay expenses which have been incurred by the
Distributor, DWR, its affiliates or other broker-dealers in excess of
payments made by the Fund pursuant to this Plan. However, with respect to
Class B, this shall not preclude consideration by the Trustees of the manner
in which such excess expenses shall be treated.

   7. This Plan may not be amended with respect to any Class to increase
materially the amount each Class may spend for distribution provided in
paragraph 1 hereof unless such amendment is approved by a vote of at least a
majority (as defined in the Act) of the outstanding voting securities of that
Class, and no material amendment to the Plan shall be made unless approved in
the manner provided for approval in paragraph 3 hereof. Class B shares will
have the right to vote on any material increase in the fee set forth in
paragraph 1(a) above affecting Class A shares.

   8. While this Plan is in effect, the selection and nomination of Trustees
who are not interested persons (as defined in the Act) of the Fund shall be
committed to the discretion of the Trustees who are not interested persons.

   9. The Fund shall preserve copies of this Plan and any related agreements
and all reports made pursuant to paragraph 5 hereof, for a period of not less
than six years from the date of this Plan, any such agreement or any such
report, as the case may be, the first two years in an easily accessible
place.

   10. The Declaration of Trust establishing Dean Witter World Wide Income 
Trust, dated October 14, 1988, a copy of which, together with all amendments
thereto (the "Declaration"), is on file in the office of the Secretary of the
Commonwealth of Massachusetts, provides that the name Dean Witter World Wide 
Income Trust refers to the Trustees under the Declaration collectively as
Trustees but not as individuals or personally; and no Trustee, shareholder,
officer, employee or agent of Dean Witter World Wide Income Trust shall be
held to any personal liability, nor shall resort be had to their private
property for this satisfaction of any obligation or claim or otherwise, in
connection with the affairs of said Dean Witter World Wide Income Trust,
but the Trust Estate only shall be liable.

                               DEAN WITTER FUNDS

                              MULTIPLE CLASS PLAN
                             PURSUANT TO RULE 18f-3
 
INTRODUCTION
 
    This plan (the "Plan") is adopted pursuant to Rule 18f-3(d) of the
Investment Company Act of 1940, as amended (the "1940 Act"), and will be
effective as of July 28, 1997. The Plan relates to shares of the open-end
investment companies to which Dean Witter InterCapital Inc. acts as investment
manager, that are listed on Schedule A, as may be amended from time to time
(each, a "Fund" and collectively, the "Funds"). The Funds are distributed
pursuant to a system (the "Multiple Class System") in which each class of shares
(each, a "Class" and collectively, the "Classes") of a Fund represents a pro
rata interest in the same portfolio of investments of the Fund and differs only
to the extent outlined below.
 
I.  DISTRIBUTION ARRANGEMENTS
 
    One or more Classes of shares of the Funds are offered for purchase by
investors with the sales load structures described below. In addition, pursuant
to Rule 12b-1 under the 1940 Act, the Funds have each adopted a Plan of
Distribution (the "12b-1 Plan") under which shares of certain Classes are
subject to the service and/or distribution fees ("12b-1 fees") described below.
 
    1.  CLASS A SHARES
 
    Class A shares are offered with a front-end sales load ("FESL"). The
schedule of sales charges applicable to a Fund and the circumstances under which
the sales charges are subject to reduction are set forth in each Fund's current
prospectus. As stated in each Fund's current prospectus, Class A shares may be
purchased at net asset value (without a FESL): (i) in the case of certain large
purchases of such shares; and (ii) by certain limited categories of investors,
in each case, under the circumstances and conditions set forth in each Fund's
current prospectus. Class A shares purchased at net asset value may be subject
to a contingent deferred sales charge ("CDSC") on redemptions made within one
year of purchase. Further information relating to the CDSC, including the manner
in which it is calculated, is set forth in paragraph 6 below. Class A shares are
also subject to payments under each Fund's 12b-1 Plan to reimburse Dean Witter
Distributors Inc., Dean Witter Reynolds Inc. ("DWR"), its affiliates and other
broker-dealers for distribution expenses incurred by them specifically on behalf
of the Class, assessed at an annual rate of up to 0.25% of average daily net
assets. The entire amount of the 12b-1 fee represents a service fee within the
meaning of National Association of Securities Dealers, Inc. ("NASD") guidelines.
 
    2.  CLASS B SHARES
 
    Class B shares are offered without a FESL, but will in most cases be subject
to a six-year declining CDSC which is calculated in the manner set forth in
paragraph 6 below. Class B shares purchased by certain qualified
employer-sponsored benefit plans are subject to a three-year declining CDSC
which is calculated in the manner set forth in paragraph 6 below. The schedule
of CDSC charges applicable to each Fund is set forth in each Fund's current
prospectus. With the exception of certain of the Funds which have a different
formula described below (Dean Witter American Value Fund, Dean Witter Natural
Resource Development Securities Inc., Dean Witter Strategist Fund and Dean
Witter Dividend Growth Securities Inc.)(1), Class B
 
- ------------
 
(1)The payments under the 12b-1 Plan for each of Dean Witter American Value
Fund, Dean Witter Natural Resource Development Securities Inc. and Dean Witter
Dividend Growth Securities Inc. are assessed at the annual rate of 1.0% of the
lesser of: (a) the average daily aggregate gross sales of the Fund's Class B
shares since the inception of the Fund's Plan (not including reinvestment of
dividends or capital gains distributions), less the average daily aggregate net
asset value of the Fund's Class B shares redeemed since the Plan's inception
upon which a contingent deferred sales charge has been imposed or waived, or (b)
the average daily net assets of Class B attributable to shares issued, net of
related shares redeemed, since inception of the Plan. The payments under the
12b-1 Plan for the Dean Witter Strategist Fund are assessed at the annual rate
of: (i) 1% of the lesser of (a) the average daily aggregate gross sales of the
Fund's Class B shares since the effectiveness of the first amendment of the Plan
on November 8, 1989 (not including reinvestment of dividends or capital gains
distributions), less the average daily aggregate net asset value of the Fund's
Class B shares redeemed since the effectiveness of the first amended Plan, upon
which a contingent deferred sales charge has been imposed or waived, or (b) the
average daily net assets of Class B attributable to shares issued, net of
related shares redeemed, since the effectiveness of the first amended Plan; plus
(ii) 0.25% of the average daily net assets of Class B attributable to shares
issued, net of related shares redeemed, prior to effectiveness of the first
amended Plan.
 
                                       1
<PAGE>
shares are also subject to a fee under each Fund's respective 12b-1 Plan,
assessed at the annual rate of up to 1.0% of either: (a) the lesser of (i) the
average daily aggregate gross sales of the Fund's Class B shares since the
inception of the Fund (not including reinvestment 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 (ii) the average daily net assets of Class B; or (b) the
average daily net assets of Class B. A portion of the 12b-1 fee equal to up to
0.25% of the Fund's average daily net assets is characterized as a service fee
within the meaning of the NASD guidelines and the remaining portion of the 12b-1
fee, if any, is characterized as an asset-based sales charge. Also, Class B
shares have a conversion feature ("Conversion Feature") under which such shares
convert to Class A shares after a certain holding period. Details of the
Conversion Feature are set forth in Section IV below.
 
    3.  CLASS C SHARES
 
    Class C shares are offered without imposition of a FESL, but will in most
cases be subject to a CDSC of 1.0% on redemptions made within one year after
purchase. Further information relating to the CDSC is set forth in paragraph 6
below. In addition, Class C shares, under each Fund's 12b-1 Plan, are subject to
12b-1 payments to reimburse Dean Witter Distributors Inc., DWR, its affiliates
and other broker-dealers for distribution expenses incurred by them specifically
on behalf of the Class, assessed at the annual rate of up to 1.0% of the average
daily net assets of the Class. A portion of the 12b-1 fee equal to up to 0.25%
of the Fund's average daily net assets is characterized as a service fee within
the meaning of NASD guidelines. Unlike Class B shares, Class C shares do not
have the Conversion Feature.
 
    4.  CLASS D SHARES
 
    Class D shares are offered without imposition of a FESL, CDSC or a 12b-1 fee
for purchases of Fund shares by (i) investors meeting an initial minimum
investment requirement and (ii) certain other limited categories of investors,
in each case, as may be approved by the Boards of Directors/Trustees of the
Funds and as disclosed in each Fund's current prospectus.
 
    5.  ADDITIONAL CLASSES OF SHARES
 
    The Boards of Directors/Trustees of the Funds have the authority to create
additional Classes, or change existing Classes, from time to time, in accordance
with Rule 18f-3 under the 1940 Act.
 
    6.  CALCULATION OF THE CDSC
 
    Any applicable CDSC is calculated based upon the lesser of net asset value
of the shares at the time of purchase or at the time of redemption. The CDSC
does not apply to amounts representing an increase in share value due to capital
appreciation and shares acquired through the reinvestment of dividends or
capital gains distributions. The CDSC schedule applicable to a Fund and the
circumstances in which the CDSC is subject to waiver are set forth in each
Fund's prospectus.
 
II.  EXPENSE ALLOCATIONS
 
    Expenses incurred by a Fund are allocated among the various Classes of
shares pro rata based on the net assets of the Fund attributable to each Class,
except that 12b-1 fees relating to a particular Class are 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 Fund's Board of Directors/Trustees.
 
III.  CLASS DESIGNATION
 
    All shares of the Funds held prior to July 28, 1997 (other than the shares
held by certain employee benefit plans established by DWR and its affiliate, SPS
Transaction Services, Inc., shares of Funds offered with a FESL, and shares of
Dean Witter Balanced Growth Fund and Dean Witter Balanced Income Fund) have been
designated Class B shares. Shares held prior to July 28, 1997 by such employee
benefit plans have been designated Class D shares. Shares held prior to July 28,
1997 of Funds offered with a FESL have been designated Class D shares. In
addition, shares of Dean Witter American Value Fund purchased prior to April 30,
1984, shares of Dean Witter Strategist Fund purchased prior to November 8, 1989
and shares of Dean Witter Natural Resource Development Securities Inc. and Dean
Witter Dividend Growth Securities Inc. purchased prior to July 2, 1984 (with
respect to such shares of each Fund, including such proportion of shares
acquired through reinvestment of dividends and capital gains distributions as
the total number of shares acquired prior to each of the preceding dates in this
sentence bears to the total number of shares purchased and owned by the
shareholder of that Fund) have been designated Class D shares. Shares of Dean
Witter Balanced Growth Fund and Dean Witter Balanced Income Fund held prior to
July 28, 1997 have
 
                                       2
<PAGE>
been designated Class C shares except that shares of Dean Witter Balanced Growth
Fund and Dean Witter Balanced Income Fund held prior to July 28, 1997 that were
acquired in exchange for shares of an investment company offered with a CDSC
have been designated Class B shares and those that were acquired in exchange for
shares of an investment company offered with a FESL have been designated Class A
shares.
 
IV.  THE CONVERSION FEATURE
 
    Class B shares held before May 1, 1997 will convert to Class A shares in
May, 2007, except that Class B shares which are purchased before July 28, 1997
by trusts for which Dean Witter Trust Company ("DWTC") or Dean Witter Trust FSB
("DWTFSB") provides discretionary trustee services will convert to Class A
shares on or about August 29, 1997 (the CDSC will not be applicable to such
shares upon the conversion). In all other instances, Class B shares of each Fund
will automatically convert 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.
Conversions will be effected once a month. The 10 year period will be 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. Except as set forth below, 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 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 held by a 401(k) plan or other employer-sponsored plan
qualified under Section 401(a) of the Internal Revenue Code (the "Code") and for
which DWTC or DWTFSB serves as Trustee or the 401(k) Support Services Group of
DWR serves as recordkeeper, all Class B shares will convert to Class A shares on
the conversion date of the first shares of a Fund purchased by that plan. In the
case of Class B shares previously exchanged for shares of an "Exchange Fund" (as
such term is defined in the prospectus of each Fund), 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 Fund, the holding period resumes on the last day of the month in
which Class B shares are reacquired.
 
    Effectiveness of the Conversion Feature is subject to the continuing
availability of a ruling of the Internal Revenue Service or an opinion of
counsel to the effect that (i) the conversion of shares does not constitute a
taxable event under the 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 fees under the applicable Fund's 12b-1 Plan.
 
V.  EXCHANGE PRIVILEGES
 
    Shares of each Class may be exchanged for shares of the same Class of the
other Funds and for shares of certain other investment companies without the
imposition of an exchange fee as described in the prospectuses and statements of
additional information of the Funds. The exchange privilege of each Fund may be
terminated or revised at any time by the Fund upon such notice as may be
required by applicable regulatory agencies as described in each Fund's
prospectus.
 
VI.  VOTING
 
    Each Class shall have exclusive voting rights on any matter that relates
solely to its 12b-1 Plan, except that Class B shareholders will have the right
to vote on any proposed material increase in Class A's expenses, including
payments under the Class A 12b-1 Plan, if such proposal is submitted separately
to Class A shareholders. If the amount of expenses, including payments under the
Class A 12b-1 Plan, is increased materially without the approval of Class B
shareholders, the Fund will establish a new Class A for Class B shareholders
whose shares automatically convert on the same terms as applied to Class A
before the increase. In addition, each Class shall have separate voting rights
on any matter submitted to shareholders in which the interests of one Class
differ from the interests of any other Class.
