Fee               scaled down on assets over $500 million (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 0.25% of the average daily net assets of the Class are currently each characterized as a
                  service fee within the meaning of the National Association of Securities Dealers, Inc. guidelines.
                  The remaining portion of the 12b-1 fee, if any, is characterized as an asset-based sales charge (see
                  pages 16 and 24).
- ----------------------------------------------------------------------------------------------------------------------
Alternative       Four classes of shares are offered:
Purchase
Arrangements      - Class A shares are offered with a front-end sales charge, starting at 5.25% and reduced for larger
                  purchases. Investments of $1 million or more (and investments by certain other limited categories of
                  investors) are not subject to any sales charge at the time of purchase but a contingent deferred
                  sales charge ("CDSC") of 1.0% may be imposed on redemptions within one year of purchase. The Fund is
                  authorized to reimburse the Distributor for specific expenses incurred in promoting the distribution
                  of the Fund's Class A shares and servicing shareholder accounts pursuant to the Fund's 12b-1 Plan.
                  Reimbursement may in no event exceed an amount equal to payments at an annual rate of 0.25% of
                  average daily net assets of the Class (see pages 16, 19 and 24).

<TABLE>
<S>               <C>
                  - Class B shares are offered without a front-end sales charge, but will in most cases be subject to
                  a CDSC (scaled down from 5.0% to 1.0%) if redeemed within six years after purchase. The CDSC will be
                  imposed on any redemption of shares if after such redemption the aggregate current value of a Class
                  B account with the Fund falls below the aggregate amount of the investor's purchase payments made
                  during the six years preceding the redemption. 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 1.0% of the lesser of: (a) the average daily net sales of the Fund's Class B shares or (b) the
                  average daily net assets of Class B. All shares of the Fund held prior to July 28, 1997 have been
                  designated Class B shares. Shares held before May 1, 1997 will convert to Class A shares in May,
                  2007. In all other instances, Class B shares convert to Class A shares approximately ten years after
                  the date of the original purchase (see pages 16, 21 and 24).
 
                  - Class C shares are offered without a front-end sales charge, but will in most cases be subject to
                  a CDSC of 1.0% if redeemed within one year after purchase. The Fund is authorized to reimburse the
                  Distributor for specific expenses incurred in promoting the distribution of the Fund's Class C
                  shares and servicing shareholder accounts pursuant to the Fund's 12b-1 Plan. Reimbursement may in no
                  event exceed an amount equal to payments at an annual rate of 1.0% of average daily net assets of
                  the Class (see pages 16 and 24).
 
                  - Class D shares are offered only to investors meeting an initial investment minimum of $5 million
                  and to certain other limited categories of investors. Class D shares are offered without a front-end
                  sales charge or CDSC and are not subject to any 12b-1 fee (see pages 16 and 24).
- ----------------------------------------------------------------------------------------------------------------------
Dividends         Dividends from net investment income are paid quarterly and distributions from net capital gains, if
and               any, are paid at least once per year. The Fund may, however, determine to retain all or part of any
Capital Gains     net long-term capital gains in any year for reinvestment. Dividends and capital gains distributions
Distributions     paid on shares of a Class are automatically reinvested in additional shares of the same Class at net
                  asset value unless the shareholder elects to receive cash. Shares acquired by dividend and
                  distribution reinvestment will not be subject to any sales charge or CDSC (see pages 27 and 31).
- ----------------------------------------------------------------------------------------------------------------------
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 30).
- ----------------------------------------------------------------------------------------------------------------------
Risks             The net asset value of the Fund's shares will fluctuate with changes in market value of portfolio
                  securities. The utilities industry has certain characteristics and risks, and developments within
                  that industry will affect the Fund's portfolio. The value of debt securities (and, to a lesser
                  extent, equity securities) issued by utilities industry issuers tends to have an inverse
                  relationship to movement of interest rates. It should be recognized that the foreign securities and
                  markets in which the Fund will invest pose different and greater risks than those customarily
                  associated with domestic securities and their markets (see page 8).

    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.

    "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 0.25% OF THE AVERAGE DAILY NET ASSETS OF THE CLASS 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 1.00% 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 Global Utilities Fund (the "Fund") is an open-end 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 The
Commonwealth of Massachusetts on October 22, 1993.
 
   
    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 (the "Dean Witter Funds"),
thirty of which are listed on the New York Stock Exchange, with combined assets
of approximately $93.1 billion at 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
Board of Trustees reviews the various services provided by the Investment
Manager to ensure that the Fund's general investment policies and programs are
being properly carried out and that administrative services are being provided
to the Fund in a satisfactory manner.
 
   
    As full compensation for the services and facilities furnished to the Fund
and for expenses of the Fund assumed by the Investment Manager, the Fund pays
the Investment Manager monthly compensation calculated daily by applying a
percentage rate to the Fund's daily net assets which declines as net assets of
the Fund reach levels over $500 million. For the fiscal year ended February 28,
1997, the Fund accrued total compensation to the Investment Manager amounting to
0.65% of the Fund's average daily net assets and the Fund's total expenses
amounted to 1.82% of the Fund's average daily net assets.
    
 
INVESTMENT OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------
 
    The investment objective of the Fund is to seek both capital appreciation
and current income. The objective is a fundamental policy of the Fund and may
not be changed without shareholder approval. There is no assurance that the
objective will be achieved.
 
    The Fund will attempt to meet its investment objective by investing (at
least 65% of its total assets) in equity and fixed-income securities of issuers
worldwide, which are primarily engaged in the utilities industry. The Fund's
investment portfolio will be invested in at least three separate countries.
 
    The term "utilities industry" describes companies engaged in the
manufacture, production, generation, transmission, sale and distribution of
water, gas and electric energy, or who manufacture or supply equipment for such
companies, as well as companies engaged in the communications field and the
companies which manufacture or supply equipment for such companies, including
telephone, telegraph, satellite, cable, microwave, radio-telephone, computer,
mobile communication and cellular paging, electronic mail, videotext and
teletext and other new or emerging technology companies. A
com-
 
                                       7
<PAGE>
pany will be considered to be in the utilities industry if, during the most
recent twelve month period, at least 50% of the company's gross revenues, on a
consolidated basis, are derived from the utilities industry. Under ordinary
circumstances, at least 65% of the Fund's total assets will be invested in
securities of companies in the utilities industry.
 
    The principal currencies in which securities held in the Fund's portfolio
will be denominated are: the U.S. dollar; Australian dollar; Deutsche mark;
Japanese yen; French franc; British pound; Canadian dollar; Mexican peso; Swiss
franc; Dutch guilder; Hong Kong dollar; New Zealand dollar; Spanish Peseta;
Swedish Krona; and European Currency Unit.
 
    The Investment Manager believes the Fund's investment policies are suited to
benefit from certain characteristics and historical performance of the
securities of utility companies. Many of these companies have historically set a
pattern of paying regular dividends over time, and the average common stock
dividend yield of utilities historically has substantially exceeded that of
industrial stocks. The Investment Manager believes that these factors may not
only provide current income but also generally tend to moderate risk and thus
may enhance the opportunity for appreciation of securities owned by the Fund,
although the potential for capital appreciation has historically been lower for
many utility stocks compared with most industrial stocks. There can be no
assurance that the historical investment performance of the utilities industry
will be indicative of future events and performance.
 
    The Fund invests in both equity securities (common stock and securities
convertible into common stock) and fixed-income securities (bonds and preferred
stock) in the utilities industry. The Fund will shift its asset allocation
without restriction between types of utilities, among nationalities of issuers
and between equity and fixed-income securities, based upon the Investment
Manager's determination of how to achieve the Fund's investment objective in
light of prevailing market, economic and financial conditions.
 
    Criteria utilized by the Investment Manager in the selection of equity
securities include the following considerations: earnings and dividend growth;
book value; dividend discount; and price/earnings relationships. In addition,
the Investment Manager makes continuing assessments of management, the
prevailing regulatory framework and industry trends. The Investment Manager may
also utilize computer-based equity selection models. In keeping with the Fund's
objective, if in the opinion of the Investment Manager favorable conditions for
capital growth of equity securities are not prevalent at a particular time, the
Fund may allocate its assets predominantly or exclusively in debt securities
with the aim of obtaining current income and thus benefitting long term growth
of capital.
 
    The Fund may purchase equity securities sold on the New York, American and
other domestic and foreign stock exchanges and in the over-the-counter market.
Fixed-income securities in which the Fund may invest are debt securities and
preferred stocks which are rated at the time of purchase Baa or better by
Moody's Investors Service, Inc. ("Moody's") or BBB or better by Standard &
Poor's Corporation ("S&P") or which, if unrated, are deemed to be of comparable
quality by the Fund's Investment Manager. Under normal circumstances, the
average weighted maturity of the fixed-income securities held by the Fund is
expected to be in excess of seven years. A description of corporate bond ratings
is contained in the Appendix to the Statement of Additional Information.
 
    Investments in fixed-income securities rated either BBB by S&P or Baa by
Moody's (the lowest credit ratings designated "investment grade") have
speculative characteristics and, therefore, changes in economic conditions or
other circumstances are more likely to weaken their capacity to make principal
and interest payments than would be the case with investments in securities with
higher credit ratings. If a fixed-income security held by the Fund is rated BBB
or Baa and is subsequently downgraded by a rating agency, the Fund will retain
such security in its portfolio until the Investment Manager
deter-
 
                                       8
<PAGE>
mines that it is practicable to sell the security without undue market or tax
consequences to the Fund. In the event that such downgraded securities
constitute 5% or more of the Fund's net assets, the Investment Manager will sell
such securities as soon as is practicable, in sufficient amounts to reduce the
total to below 5%.
 
    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 arrangement.
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 net assets are invested in cash or
money market instruments. Money market instruments in which the Fund may invest
are securities issued or guaranteed by the U.S. Government (Treasury bills,
notes and bonds, including zero coupon securities); bank obligations (such as
certificates of deposit and bankers' acceptances); Yankee instruments;
Eurodollar certificates of deposit; obligations of savings institutions; fully
insured certificates of deposit; and commercial paper 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 AND INVESTMENT PRACTICES
 
    UTILITIES INDUSTRY.  The utilities industry as a whole has certain
characteristics and risks particular to that industry. Unlike industrial
companies, the rates which utility companies may charge their customers
generally are subject to review and limitation by governmental regulatory
commissions. Although rate changes of a utility usually fluctuate in approximate
correlation with financing costs, due to political and regulatory factors, rate
changes ordinarily occur only following a delay after the changes in financing
costs. This factor will tend to favorably affect a utility company's earnings
and dividends in times of decreasing costs, but conversely will tend to
adversely affect earnings and dividends when costs are rising. In addition, the
value of utility debt securities (and, to a lesser extent, equity securities)
tends to have an inverse relationship to the movement of interest rates.
 
    Among the risks affecting the utilities industry are the following: risks of
increases in fuel and other operating costs; the high cost of borrowing to
finance capital construction during inflationary periods; restrictions on
operations and increased costs and delays associated with compliance with
environmental and nuclear safety regulations; the difficulties involved in
obtaining natural gas for resale or fuel for generating electricity at
reasonable prices; the risks in connection with the construction and operation
of nuclear power plants; the effects of energy conservation and the effects of
regulatory changes, such as the possible adverse effects on profits of recent
increased competition among telecommunications companies and the uncertainties
resulting from such companies' diversification into new domestic and
international businesses, as well as agreements by many such companies linking
future rate increases to inflation or other factors not directly related to the
actual operating profits of the enterprise.
 
    FOREIGN SECURITIES.  Foreign securities investments may be affected by
changes in currency rates or exchange control regulations, changes in
governmental administration or economic or monetary policy (in the United States
and abroad) or changed circumstances in dealings between nations. Fluctuations
in the relative rates of
 
                                       9
<PAGE>
exchange between the currencies of different nations will affect the value of
the Fund's investments denominated in foreign currency. 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 total return on such assets.
 
    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 foreign currency
exchange contracts (described below). The Fund will 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 subject to uniform
accounting, auditing and financial reporting 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 the Fund's trades effected in such markets. As such, the
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 the extent the Fund purchases Eurodollar
certificates of deposit issued by foreign branches of domestic United States
banks, consideration will be given to their domestic marketability, the lower
reserve requirements normally mandated for overseas banking operations, the
possible impact of interruptions in the flow of international currency
transactions and future international political and economic developments which
might adversely affect the payment of principal or interest.
 
    Certain of the foreign markets in which the Fund may invest will be emerging
markets. These new and incompletely formed markets will have increased risk
levels above those occasioned by investing in foreign markets generally. The
types of these risks are set forth above. The Fund's management will take
cognizance of these risks in allocating any of the Fund's investments in either
fixed-income or equity securities issued by issuers in emerging market
countries.
 
    FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS. The Fund may enter into forward
foreign currency exchange contracts ("forward contracts") in connection with its
foreign securities investments.
 
    A 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.
 
                                       10
<PAGE>
    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 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 (by the Fund or the
counterparty) 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, the Fund 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 securities holdings (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.
This method of hedging, called "cross-hedging," will be selected by the
Investment Manager when it is determined that the foreign currency in which the
portfolio securities are denominated has insufficient liquidity or is 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, the Fund 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.
 
    In all of the above circumstances, if the currency in which the Fund
securities holdings (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. The Fund may be limited in
its ability to enter into hedging transactions involving forward contracts by
the Internal Revenue Code requirements relating to qualification as a regulated
investment company (see "Dividends, Distributions and Taxes").
 
    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 government securities or other securities
 
                                       11
<PAGE>
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 to minimize such risks. These
procedures include effecting repurchase transactions only with large, well-
capitalized and well-established financial institutions and maintaining adequate
collateralization.
 
    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 or delayed delivery 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.
 
    REVERSE REPURCHASE AGREEMENTS AND DOLLAR ROLLS.  The Fund may also use
reverse repurchase agreements and dollar rolls 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. The Fund may enter into dollar rolls in which
the Fund sells securities and simultaneously contracts to repurchase
substantially similar (same type and coupon) securities on a specified future
date. Reverse repurchase agreements and dollar rolls 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 or dollar roll files for
bankruptcy or becomes insolvent, the Fund's use of 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 and dollar rolls are speculative techniques
involving leverage (which may increase investment risk), and are considered
borrowings by the Fund.
 
    PRIVATE PLACEMENTS.  The Fund may invest up to 5% 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 under 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
 
                                       12
<PAGE>
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 security is determined to be "liquid," such security will
not be included within the category "illiquid securities," which under current
policy may not exceed 15% of the Fund's net assets. However, investing in Rule
144A securities could have the effect of increasing the level of Fund
illiquidity to the extent the Fund, at a particular point in time, may be unable
to find qualified institutional buyers interested in purchasing such securities.
 
    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.
 
OPTIONS AND FUTURES TRANSACTIONS
 
    The Fund may purchase and sell (write) call and put options on portfolio
securities which are denominated in either U.S. dollars or foreign currencies
and on the U.S. dollar and foreign currencies, which are or may in the future be
listed on several U.S. and foreign securities exchanges or are written in
over-the-counter transactions ("OTC options"). OTC options are purchased from or
sold (written) to dealers or financial institutions which have entered into
direct agreements with the Fund.
 
    The Fund is permitted to write covered call options on portfolio securities
and the U.S. dollar and foreign currencies, without limit, in order to hedge
against the decline in the value of a security or currency in which such
security is denominated (although such hedge is limited to the value of the
premium received), to close out long call option positions and to generate
income. The Fund may write covered put options, under which 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.
 
    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 covered 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. The Fund may also
purchase put options
 
                                       13
<PAGE>
to close out written put positions in a manner similar to call option closing
purchase transactions. There are no other limits on the Fund's ability to
purchase call and put options.
 
    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
underlying portfolio securities, on any currency ("currency" futures), on U.S.
and foreign fixed-income securities ("interest rate" futures) and on such
indexes of U.S. or foreign equity or fixed-income securities as may exist or
come into being ("index" futures). The Fund may purchase or sell interest rate
futures contracts for the purpose of hedging some or all of the value of its
portfolio securities (or anticipated portfolio securities) against changes in
prevailing interest rates. The Fund may purchase or sell index futures contracts
for the purpose of hedging some or all of its portfolio securities (or
anticipated portfolio securities) against changes in their prices (or the
currency in which they are denominated.) 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 also 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.
 
    New futures contracts, options and other financial products and various
combinations thereof continue to be developed. The Fund may invest in any such
futures, options or products as may be developed, to the extent consistent with
its investment objective and applicable regulatory requirements.
 
    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 may generally only be closed out by
entering into a closing purchase transaction with the purchasing dealer. Also,
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.
 
    Futures contracts and options transactions may be considered speculative in
nature and may involve greater risks than those customarily assumed by other
investment companies which do not invest in 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 will 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. See the Statement of
Additional Information for a further discussion of risks.
 
PORTFOLIO MANAGEMENT
 
   
    The Fund's portfolio is actively managed by its Investment Manager with a
view to achieving the Fund's investment objective. In determining which
securities to purchase for the Fund or hold in the Fund's portfolio, the
Investment Manager will rely on information from various sources, including
research, analysis and appraisals of brokers and dealers, including Dean Witter
Reynolds Inc. ("DWR"), and other broker-dealer affiliates of Inter-
    
 
                                       14
<PAGE>
   
Capital, and others regarding economic developments and interest rate trends,
and the Investment Manager's own analysis of factors it deems relevant. The
Fund's portfolio is managed within InterCapital's Income and Growth Group, which
manages twenty-two funds and fund portfolios with approximately $23.9 billion in
assets as of March 31, 1997. Edward F. Gaylor, Senior Vice President of
InterCapital and a member of InterCapital's Income and Growth Group, has been
the primary portfolio manager of the Fund since its inception. Mr. Gaylor has
been managing portfolios comprised of equity and fixed-income securities at
InterCapital for over five years.
    
 
   
    Although the Fund does not engage in substantial short-term trading as a
means of achieving its investment objective, it may sell portfolio securities
without regard to the length of time they have been held, in accordance with the
investment policies described earlier. Pursuant to an order of the Securities
and Exchange Commission, the Fund may effect principal transactions in certain
money market instruments with DWR. Orders for transactions in portfolio
securities and commodities are placed for the Fund with a number of brokers and
dealers including DWR and other brokers and dealers that are affiliates of
InterCapital. The Fund may incur brokerage commissions on transactions conducted
through such affiliates. Under normal circumstances, it is not anticipated that
the portfolio trading will result in the Fund's portfolio turnover rate
exceeding 100% in any one year.
    
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    The investment restrictions listed below are among the restrictions which
have been adopted by the Fund as fundamental policies. Under the Investment
Company Act of 1940, as amended (the "Act"), a fundamental policy may not be
changed without the vote of a majority of the outstanding voting securities of
the Fund, as defined in the Act. 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. As to 75% of its total assets, invest more than 5% of the value of its
total assets in the securities of any one issuer (other than obligations issued
or guaranteed by the United States Government, its agencies or
instrumentalities).
 
   2. Invest 25% or more of the value of its total assets in securities of
issuers in any one industry, with the exception of the utilities industry. This
restriction does not apply to obligations issued or guaranteed by the United
States Government, its agencies or instrumentalities.
 
   3. 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.
 
   4. As to 75% of its total assets, purchase more than 10% of the voting
securities, or more than 10% of any class of securities, of any issuer.
 
   
    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 "Distributors"), an affiliate of the Investment
Manager, shares of the Fund are distributed by the Distributor and offered by
DWR and other dealers who have entered into 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 Global Utilities Fund, 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
purchases pursuant to Systematic Payroll Deduction Plans (including Individual
Retirement Plans), the Fund, in its discretion, may accept such purchases
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 pur-
    
 
                                       16
<PAGE>
   
chased will not be issued 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
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 at the time of their sale by the Distributor or any of its affiliates
and/or the Selected Broker-Dealer. In addition, some sales personnel of the
Selected Broker-Dealer will receive 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 5.25%. 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 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 (not including
reinvestments of divi-
    
 
                                       17
<PAGE>
   
dends 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 1.0% 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 1.0% (rather than the 0.25% fee applicable to Class A shares) for
an indefinite period of time. Thus, Class B shares may be more attractive than
Class C shares to investors with longer term investment outlooks. Other
investors, however, may elect to purchase Class C shares if, for example, they
determine that they do not wish to be subject to a front-end sales charge and
they are uncertain as to the length of time they intend to hold their shares.
    
 
   
    For the purpose of meeting the $5 million minimum investment amount for
Class D shares, holdings of Class A shares in all Dean Witter Multi-Class Funds,
shares of FSC Funds and shares of Dean Witter Funds for which such shares have
been exchanged will be included together with the current investment amount.
    
 
   
    Sales personnel may receive different compensation for selling each Class of
shares. Investors should understand that the purpose of a CDSC is
    
 
                                       18

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

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

    Upon notice to all Selected Broker-Dealers, the Distributor may reallow up
to the full applicable sales charge as shown in the above schedule during
periods specified in such notice. During periods when 90% or more of the sales
charge is reallowed, such Selected Broker-Dealers may be deemed to be
underwriters as that term is defined in the Securities Act of 1933.
    
 
                                       19

    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
sales charge, which are still owned by the shareholder, may also be included in
determining the applicable reduction.

    ADDITIONAL NET ASSET VALUE PURCHASE OPTIONS. In addition to investments of
$1 million or more, Class A shares also may be purchased at net asset value by
the following:
    
 
   
   (1) trusts for which 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
of investment advisory or administrative services (such investments are subject
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
Code ("401(k) plans") and other employer-sponsored plans qualified under Section
401(a) of the Internal Revenue Code with at least 200 eligible employees and for
which DWTC or DWTFSB serves as Trustee or the 401(k) Support Services Group of
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
or the 401(k) Support Services Group of DWR serves as recordkeeper whose Class B
shares have converted to Class A shares, regardless of the plan's asset size or
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
disclosed in the then current prospectus of the Fund.
    
 
   
    No CDSC will be imposed on redemptions of shares purchased pursuant to
paragraphs (1), (2) or (5), above.
    
 
   
    For further information concerning purchases of the Fund's shares, contact
DWR or another Selected Broker-Dealer or consult the Statement of Additional
Information.
    
 
   
CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE-- CLASS B SHARES
    
 
   
    Class B shares are sold at net asset value next determined without an
initial sales charge so that the full amount of an investor's purchase payment
may be immediately invested in the Fund. A CDSC, however, will be imposed on
most Class B shares redeemed within six years after purchase. The CDSC will be
imposed on any redemption of shares if after such redemption the aggregate
current value of a Class B account with the Fund falls below the aggregate
amount of the investor's purchase payments for Class B shares made during the
six years (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 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 (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 subject to any CDSC upon redemption.
Shares redeemed earlier than six years after purchase may,
    
 
                                       21
<PAGE>
   
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:

    In the case of Class B shares of the Fund held by 401 (k) plans or other

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
redemption. However, shares redeemed earlier than three years after purchase may
be subject to a CDSC (calculated as described in the paragraph above), the
percentage of which will depend on how long the shares have been held, as set

    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
other open-end investment companies for which InterCapital serves as investment
manager (collectively, with the Fund, the "Dean Witter Funds") sold with a
front-end sales charge or of other Dean Witter Funds acquired in exchange for
such shares. Moreover, in determining whether a CDSC is applicable it will be
assumed that amounts described in (i), (ii) and (iii) above (in that order) are
redeemed first.
    
 
   
    In addition, the CDSC, if otherwise applicable, will be waived in the case
of:
    
 
   
   (1) redemptions of shares held at the time a shareholder dies or becomes
disabled, only if the shares are:  (a) registered either in the name of an
individual shareholder (not a trust), or in the names of such shareholder and
his or her spouse as joint tenants with right of survivorship; or  (b) held in a
qualified corporate or self-employed retirement plan, Individual Retirement
Account ("IRA") or Custodial Account under Section 403(b)(7) of the Internal
Revenue Code ("403(b) Custodial Account"), provided in either case that the
redemption is requested within one year of the death or initial determination of
disability;
    
 
   
   (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
    
 
                                       22
<PAGE>
   
the Internal Revenue Code which offers investment 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
conver-
    
 
                                       23
<PAGE>
   
sion will have a holding period that includes the holding period of the
converted Class B shares. The conversion feature may be suspended if the ruling
or opinion is no longer available. In such event, Class B shares would continue
to be subject to Class B 12b-1 fees.
    
 
   
    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 1.0% 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 1.0% of the average daily net assets of Class A
and Class C, respectively. In the case of Class B shares, the Plan
    
 
                                       24
<PAGE>
   
provides that the Fund will pay the Distributor a fee, which is accrued daily
and paid monthly, 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 (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 0.25% of the
average daily net assets of each of these Classes, 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 February 28, 1997, Class B shares of the Fund
accrued payments under the Plan amounting to $3,227,912, which amount is equal
to 0.91% of the Fund's average daily net assets for the fiscal year. The
payments accrued under the Plan were calculated pursuant to clause (a) 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
$11,326,626 at February 28, 1997, which was equal to 3.22% 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 1.0% of the average daily net
assets of Class A or Class C, respectively, will not be reimbursed by the Fund
through
    
 
                                       25
<PAGE>
   
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; if there were no sales that day, the security is valued at the latest
bid price (in cases where a security is traded on more than one exchange, the
security is 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 bid price. 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 Board of
Trustees.
 
    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 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 some Trustees.
 
    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.

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").
    
 
   
    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").
    
 
   
    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").
    
 
   
    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, custody fees and
other details, investors should contact their account executive or the Transfer
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
    
 
                                       27
<PAGE>
   
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 EXCHANGES. Purchases and exchanges should
be made for investment purposes only. A pattern of frequent exchanges may be
deemed by the Investment Manager to be abusive and contrary to the best
interests of the Fund's other shareholders and, at the Investment Manager's
discretion, may be limited by the Fund's refusal to accept additional purchases
and/ or exchanges from the investor. Although the Fund does not have any
specific definition of what constitutes a pattern of frequent exchanges, and
will consider all relevant factors in determining whether a particular situation
is abusive and contrary to the best interests of the Fund and its other
shareholders, investors should be aware that the Fund and each of the other Dean
Witter Funds may in their discretion limit or otherwise restrict the number of
times this Exchange Privilege may be exercised by any investor. Any such
restriction will be made by
    
 
                                       28
<PAGE>
   
the Fund on a prospective basis only, upon notice of 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 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-Dealers but who wish to make
exchanges directly by writing or telephoning the Transfer Agent) must complete
and forward to the Transfer Agent an Exchange Privilege Authorization Form,
copies of which may be obtained from the Transfer Agent, to initiate an
exchange. If the Authorization Form is used, exchanges may be made in writing or
by contacting the Transfer Agent at (800) 869-NEWS (toll-free).
    
 
    The Fund will employ reasonable procedures to confirm that exchange
instructions communicated over the telephone are genuine. Such procedures may
include requiring various forms of personal identification such as name, mailing
address, social security or other tax identification number and DWR or other
Selected Broker-Dealer account number (if any). Telephone instructions may also
be recorded. If such procedures are not employed, the Fund may be liable for any
losses due to unauthorized or fraudulent instructions.
 
    Telephone exchange instructions will be accepted if received by the Transfer
Agent between 9:00 a.m. and 4:00 p.m., New York time, on any day the New York
Stock Exchange is open. Any shareholder wishing to make an exchange who has
previously filed an Exchange Privilege Authorization Form and who is unable to
reach the Fund by telephone should contact his or her DWR or other Selected
Broker-Dealer account executive, if appropriate, 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 experience 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.

<PAGE>
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 upon redemption by either the
Fund or the Distributor. The offer by DWR and other Selected Broker-Dealers to
repurchase shares may be suspended without notice by the Distributor 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; E.G., when normal trading is not taking place on the New York
Stock Exchange. If the shares to be redeemed have recently been purchased by
check, payment of the redemption proceeds may be delayed for the minimum time
needed to verify that the check used for investment has been honored (not more
than fifteen days from the time of receipt of the check by the Transfer Agent).
Shareholders maintaining margin accounts with DWR or another Selected Broker-
Dealer are referred to their account executive regarding restrictions on
redemption of shares of the Fund pledged in the margin account.
 
   
    REINSTATEMENT PRIVILEGE.  A shareholder who has had his or her shares
redeemed or repurchased and has not previously exercised this reinstatement
privilege may, within 35 days after the date of the redemption or repurchase,
reinstate any portion or all of the proceeds of such redemption or repurchase in
shares of the Fund in the same Class from which such shares were redeemed or
repurchased, at their net asset value next determined after a reinstatement
request, together with the proceeds, is received by the Transfer Agent and
receive a pro rata credit for any CDSC paid in connection with such redemption
or repurchase.
    
 
    INVOLUNTARY REDEMPTION.  The Fund reserves the right to redeem, on sixty
days' notice and at net asset value, the shares of any shareholder (other than
shares held in an Individual Retirement Account or Custodial Account under
Section 403(b)(7) of the Internal Revenue Code) whose shares 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-SM-, if after twelve months the shareholder has invested less than
$1,000 in the account. However, before the Fund redeems such shares and sends
the proceeds to the shareholder, it will notify the shareholder that the value
of the shares is less than the applicable amount and allow him or her sixty days
to make an additional investment in an amount which will increase the value of
his or her account to at least the applicable amount before the redemption is
processed. No CDSC will be imposed on any involuntary redemption.

<PAGE>
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
   
    DIVIDENDS AND DISTRIBUTIONS.  The Fund declares dividends separately for
each Class of shares and intends to pay quarterly 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 to retain all or part of any net
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 capital gains to shareholders and otherwise remain
qualified as a regulated investment company under Subchapter M of the Internal
Revenue Code, it is not expected that the Fund will be required to pay any
Federal income tax on any such income and capital gains. Shareholders will
normally have to pay Federal income taxes, and any state and local income taxes,
on the dividends and distributions they receive from the Fund.
 
   
    Distributions of 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. Capital gains distributions are not eligible for
the corporate dividends received deduction. Some part of such dividends and
distributions may be eligible for the Federal dividends received deduction
available to the Fund's corporate shareholders.
    
 
    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.
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 makes 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.
 
    Shareholders should consult their tax advisers as to the applicability of
the foregoing to their current situation.

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
   
    From time to time the Fund may quote its "total return" in advertisements
and sales literature. These figures are computed separately for Class A, Class
B, Class C and Class D shares. The total return of the Fund is based upon
historical earnings and is not intended to indicate future performance. The
"average annual total return" of the Fund refers to a figure reflecting the
average annualized percentage increase (or decrease) in the value of an initial
investment in a Class of the Fund of $1,000 over periods of one, five and ten
years, as well as over the life of the Class if less than any of the foregoing.
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 of the Fund and all sales charges 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. 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. Such calculations may or may not reflect the
deduction of any sales charge which, if reflected, would reduce the performance
quoted. The Fund from time to time may also advertise its performance relative
to certain performance rankings and indexes compiled by independent
organizations, such as mutual fund performance rankings of Lipper Analytical
Services, Inc.
    
 
ADDITIONAL INFORMATION
- --------------------------------------------------------------------------------
 
   
    VOTING RIGHTS.  All shares of beneficial interest of the Fund are of $0.01
par value and are equal as to earnings, assets and voting privileges except that
each Class will have exclusive voting privileges with respect to matters
relating to distribution expenses borne solely by such Class or any other matter
in which the interests of one Class differ from the interests of any other
Class. In addition, Class B shareholders will have the right to vote on any
proposed material increase in Class A's expenses, if such proposal is submitted
separately to Class A shareholders. Also, as discussed herein, Class A, Class B
and Class C bear the expenses related to the distribution of their respective
shares.
    
 
    The Fund is not required to hold Annual Meetings of Shareholders and 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, in the opinion of Massachusetts
counsel to the Fund, the risk to shareholders of personal liability is remote.
 
    CODE OF ETHICS.  Directors, officers and employees of InterCapital, Dean

Company Inc. and the Distributor are subject to a strict Code of Ethics adopted
by those companies. The Code of Ethics is intended to ensure that the interests
of shareholders and other clients are placed ahead of any personal interest,
that no undue personal benefit is obtained from a person's employment activities
and that actual and potential conflicts of interest are avoided. To achieve
these goals and comply with regulatory requirements, the Code of Ethics
requires, among other things, that personal securities transactions by employees
of the companies be subject to an advance clearance process to monitor that no
Dean Witter Fund is engaged at the same time in a purchase or sale of the same
security. The Code of Ethics bans the purchase of securities in an initial
public offering, and also prohibits engaging in futures and options transactions
and profiting on short-term trading (that is, a purchase within sixty days of a
sale or a sale within sixty days of a purchase) of a security. In addition,
investment personnel may not purchase or sell a security for their personal
account within thirty days before or after any transaction in any Dean Witter
Fund managed by them. Any violations of the Code of Ethics are subject to
sanctions, including reprimand, demotion or suspension or termination of
employment. The Code of Ethics comports with regulatory requirements and the
recommendations in the 1994 report by the Investment Company Institute Advisory
Group on Personal Investing.
 
   
    MASTER/FEEDER CONVERSION.  The Fund reserves the right to seek to achieve
its investment objectives by investing all of its investable assets in a
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

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
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
October 22, 1993.
 
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
corporation. In an internal reorganization which took place in January, 1993,
InterCapital assumed the advisory, administrative and management activities
previously performed by the InterCapital Division of Dean Witter Reynolds Inc.
("DWR"), a broker-dealer affiliate of InterCapital. (As hereinafter used in this
Statement of Additional Information, the terms "InterCapital" and "Investment
Manager" refer to DWR's InterCapital Division prior to the internal
reorganization and to Dean Witter InterCapital Inc. thereafter.) The daily
management of the Fund and research relating to the Fund's portfolio are
conducted by or under the direction of officers of the Fund and of the
Investment Manager, subject to review by the Fund's Trustees. Information as to
these Trustees and officers is contained under the caption "Trustees and
Officers."

Fund, Dean Witter Financial Services Trust and Dean Witter Market Leader Trust.
The foregoing investment companies, together with the Fund, are collectively
referred to as the Dean Witter Funds.
 
   
    In addition, Dean Witter Services Company Inc. ("DWSC"), a wholly-owned
subsidiary of InterCapital, serves as manager for the following investment
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 Growth Fund, TCW/DW Term Trust 2002, TCW/DW Income and Growth
Fund, TCW/DW Small Cap Growth Fund, TCW/DW Balanced Fund, TCW/DW Emerging
Markets Opportunities Trust, TCW/DW Total Return Trust, TCW/DW Mid-Cap Equity
Trust, TCW/DW Global Telecom Trust, TCW/DW Strategic Income Fund, TCW/DW Term
Trust 2000 and TCW/DW Term Trust 2003 (the "TCW/DW Funds"). InterCapital also
serves as: (i) administrator of the BlackRock Strategic Term Trust Inc., a
closed-end investment company; and (ii) sub-administrator of MassMutual
Participation Investors and Templeton Global Governments Income Trust,
closed-end investment companies.
    
 
    Pursuant to an Investment Management Agreement (the "Agreement") with the
Investment Manager, the Fund has retained the Investment Manager to manage the
investment of the Fund's assets, including the placing of orders for the
purchase and sale of portfolio securities. The Investment Manager obtains and
evaluates such information and advice relating to the economy, securities
markets, and specific securities as it considers necessary or useful to
continuously manage the assets of the Fund in a manner consistent with its
investment objective.
 
    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. The Investment Manager
has retained DWSC to perform its administrative services under the Agreement.
 
   
    The Fund pays all expenses incurred in its operation. 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 "Purchase of Fund Shares") 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 of proxy
statements and reports to shareholders; fees and travel expenses of trustees or
members of any advisory board or committee who are not employees of the
Investment Manager or any corporate affiliate of the Investment Manager; all
expenses incident to any dividend, withdrawal or redemption options; charges and
expenses of any outside service used for pricing of the Fund's shares; fees and
expenses of legal counsel, including counsel to the trustees who are not
interested persons of the Fund or of the Investment Manager (not including
compensation or expenses of attorneys who are employees of the Investment
Manager) and independent accountants; membership dues of industry associations;
interest on the Fund's 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
    
 
                                       4
<PAGE>
   
(depending upon the nature of the legal claim, liability or lawsuit) and all
other costs of the Fund's operations properly payable by the Fund. The 12b-1
fees relating to a particular Class will be allocated directly to that Class. In
addition, other expenses associated with a particular Class (except advisory or
custodial fees) may be allocated directly to that Class, provided that such
expenses are reasonably identified as specifically attributable to that Class
and the direct allocation to that Class is approved by the Trustees.
    
 
   
    As full compensation for the services and facilities furnished to the Fund
and expenses of the Fund assumed by the Investment Manager, the Fund pays the
Investment Manager monthly compensation calculated daily by applying the
following annual rates to the daily net assets of the Fund: 0.65% of the portion
of daily net assets not exceeding $500 million and 0.625% on assets over $500
million. The Fund accrued total compensation to the Investment Manager of
$1,449,676, $2,282,675 and $2,295,007, during the period May 31, 1994
(commencement of operations) through February 28, 1995 and the fiscal years
ended February 29, 1996 and February 28, 1997, 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.
 
    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 between 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.
 
    The Investment Manager paid the organizational expenses of the Fund incurred
prior to the offering of the Fund's shares. The Fund has reimbursed the
Investment Manager for such expenses in accordance with the terms of the
Underwriting Agreement between the Fund and Distributors. The Fund will defer
and will amortize the reimbursed expenses on the straight line method over a
period not to exceed five years from the date of commencement of the Fund's
operations.
 
   
    The Agreement was initially approved by the Trustees of the Fund 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 December 2, 1993 and by InterCapital as the then sole shareholder
on February 24, 1994 and subsequently amended by the Trustees at their meeting
held on April 24, 1997 to provide a breakpoint in the management fee that
reduced the compensation received by the Investment Manager under the agreement
on assets exceeding $500 million. 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 Trustees of the Fund, by the holders of a majority
of the outstanding shares of the Fund, as defined in the Investment Company Act
of 1940, as amended (the "Act"), or by the Investment Manager. The Agreement
will automatically terminate in the event of its assignment (as defined in the
Act).
    
 
   
    Under its terms, the Agreement has an initial term ending April 30, 1999,
and provides that it will continue from year to year thereafter, provided
continuance of the Agreement is approved at least annually by the vote of the
holders of a majority of the outstanding shares of the Fund, as defined in the
Act, 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 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
    
 
                                       8
<PAGE>
   
June 30, 1997, the Dean Witter Funds had total net assets of approximately $87.9
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 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.
    
 
                                       9
<PAGE>
   
    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 February 28, 1997.

    As of the date of this Statement of Additional Information, 57 of the Dean
Witter Funds, not 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.
 
- ------------------------
(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
- --------------------------------------------------------------------------------
 
    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 (usually large, commercial and
investment banks) and their customers. Such forward contracts will only be
entered into with United States banks and their foreign branches 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 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 management of the Fund 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 or other appropriate liquid portfolio
securities in a segregated account of the
 
                                       12
<PAGE>
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 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 (however, the ability of the Fund to terminate a contract is
contingent upon the willingness of the currency trader with whom the contract
has been entered into to permit an offsetting transaction). 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 option on a 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 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 appropriate 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, 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.
 
                                       13
<PAGE>
    REPURCHASE AGREEMENTS.  As discussed in the Prospectus, when cash may be
available for only a few days, it may be invested by the Fund in repurchase
agreements until such time as it may otherwise be invested or used for payments
of obligations of the Fund. These agreements, which may be viewed as a type of
secured lending by the Fund, typically involve the acquisition by the Fund of
debt securities from a selling financial institution such as a bank, savings and
loan association or broker-dealer. The agreement provides that the Fund will
sell back to the institution, and that the institution will repurchase, the
underlying security ("collateral") at a specified price and at a fixed time in
the future, usually not more than seven days from the date of purchase. The
collateral will be maintained in a segregated account and will be marked to
market daily to determine that the value of the collateral, as specified in the
agreement, does not decrease below the purchase price plus accrued interest. If
such decrease occurs, additional collateral will be requested and, when
received, added to the account to maintain full collateralization. The Fund will
accrue interest from the institution until the time when the repurchase is to
occur. Although 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.
 
    While repurchase agreements involve certain risks not associated with direct
investments in debt securities, the Fund follows procedures designed to minimize
such risks. These procedures include effecting repurchase transactions only with
large, well-capitalized and well-established financial institutions whose
financial condition will be continually monitored by the Investment Manager
subject to procedures established by the Board of Trustees of the Fund. In
addition, as described above, the value of the collateral underlying the
repurchase agreement will be at least equal to the repurchase price, including
any accrued interest earned on the repurchase agreement. In the event of a
default or bankruptcy by a selling financial institution, the Fund will seek to
liquidate such collateral. However, the exercising of the Fund's right to
liquidate such collateral could involve certain costs or delays and, to the
extent that proceeds from any sale upon a default of the obligation to
repurchase were less than the repurchase price, the Fund could suffer a loss. It
is the current policy of the Fund not to invest in repurchase agreements that do
not mature within seven days if any such investment, together with any other
illiquid assets held by the Fund, amounts to more than 15% of its net assets.
The Fund's investments in repurchase agreements may at times be substantial
when, in the view of the Investment Manager, liquidity, tax or other
considerations warrant.
 
    REVERSE REPURCHASE AGREEMENTS AND DOLLAR ROLLS.  As discussed in the
Prospectus, the Fund may also use reverse repurchase agreements and dollar rolls
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.
 
    The Fund may enter into dollar rolls in which the Fund sells securities for
delivery in the current months and simultaneously contracts to repurchase
substantially similar (same type and coupon) securities on a specified future
date. During the roll period, the Fund forgoes principal and interest paid on
the securities. The Fund is compensated by the difference between the current
sales price and the lower forward price for the future purchase (often referred
to as the "drop") as well as by the interest earned on the cash proceeds of the
initial sale.
 
    The Fund will establish a segregated account with its custodian bank in
which it will maintain cash, U.S. Government Securities or other liquid
portfolio securities equal in value to its obligations in respect of reverse
repurchase agreements and dollar rolls. Reverse repurchase agreements and dollar
rolls 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
or dollar roll files for bankruptcy or becomes insolvent, the Fund's use of
proceeds of the agreement may be restricted pending a determination by the other
party, or its trustee or
 
                                       14
<PAGE>
receiver, whether to enforce the Fund's obligation to repurchase the securities.
Reverse repurchase agreements and dollar rolls are speculative techniques
involving leverage, and are considered borrowings by the Fund.
 
    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 cash equivalents, which are maintained in a segregated
account pursuant to applicable regulations and that are equal to at least 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 day's notice, or by the Fund on four business days'
notice. If the borrower fails to deliver the loaned securities within four 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 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. However, the
Fund has not to date and has no intention of lending any of its portfolio
securities during its fiscal year ending February 28, 1998.
 
    WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS.  As
discussed in the Prospectus, from time to time the Fund may purchase securities
on a when-issued or delayed delivery basis or may purchase or sell securities on
a forward commitment basis. When 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 commitment. While the Fund will only purchase
securities on a when-issued, delayed delivery or forward commitment basis with
the intention of acquiring the securities, the Fund may sell the securities
before the settlement date, if it is deemed advisable. The securities so
purchased or sold are subject to market fluctuation and no interest or dividends
accrue to the purchaser prior to the settlement date. At the time the Fund makes
the commitment to purchase or sell securities on a when-issued, delayed delivery
or forward commitment basis, it will record the transaction and thereafter
reflect the value, each day, of such security purchased, or if a sale, the
proceeds to be received, in determining its net asset value. At the time of
delivery of the securities, the value may be more or less than the purchase or
sale price. The Fund will also establish a segregated account with its custodian
bank in which it will continually maintain cash or cash equivalents or other
liquid portfolio securities equal in value to commitments to purchase securities
on a when-issued, delayed delivery or forward commitment basis. Subject to the
foregoing restrictions, the Fund may purchase securities on such basis without
limit. The Investment Manager and the Board of Trustees do not believe that the
Fund's net asset value will be adversely affected by the 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,
lever-
 
                                       15
<PAGE>
aged 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
maintain cash or cash equivalents or other liquid portfolio securities equal in
value to recognized commitments for such securities. Once a segregated account
has been established, if the anticipated event does not occur and the securities
are not issued, the Fund will have lost an investment opportunity. 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.
 
    PRIVATE PLACEMENTS.  As discussed in the Prospectus, the Fund may invest up
to 5% 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.)
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 ("SEC") 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. The procedures require that the following factors be taken into account in
making a liquidity determination: (1) the frequency of trades and price quotes
for the security; (2) the number of dealers and other potential purchasers who
have issued quotes on the security; (3) any dealer undertakings to make a market
in the security; and (4) the nature of the security and the nature of the
marketplace trades (the time needed to dispose of the security, the method of
soliciting offers, and the mechanics of transfer). If a restricted security is
determined to be "liquid," such security will not be included within the
category "illiquid securities," which under the SEC's current policies may not
exceed 15% of the Fund's net assets, and will not be subject to the 5%
limitation set out in the preceding paragraph.
 
    The Rule 144A marketplace of sellers and qualified institutional buyers is
new and still developing and may take a period of time to develop into a mature
liquid market. As such, the market for certain private placements purchased
pursuant to Rule 144A may be initially small or may, subsequent to purchase,
become illiquid. Furthermore, the Investment Manager may not posses all the
information concerning an issue of securities that it wishes to purchase in a
private placement to which it would normally have had access, had the
registration statement necessitated by a public offering been filed with the
Securities and Exchange Commission.
 
OPTIONS AND FUTURES TRANSACTIONS
 
    As stated 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
 
                                       16
<PAGE>
eligible portfolio) securities and engaging in transactions involving futures
contracts and options on such contracts. The Fund may also hedge against
potential changes in the market value of the currencies in which its investments
(or anticipated investments) are denominated by purchasing put and call options
on currencies and engage in transactions involving currency 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 and are written in over-the-counter
transactions ("OTC options"). Listed options are issued by the Options Clearing
Corporation ("OCC") and other clearing entities including foreign exchanges.
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 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 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 a
security 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. The Fund may also write options to close out long call
option positions.
 
                                       17
<PAGE>
    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 opinion of the management of the
Fund, 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 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. The Fund will engage in OTC option
transactions only with primary U.S. Government securities dealers recognized by
the Federal Reserve Bank of New York.
 
    COVERED CALL WRITING.  The Fund is permitted to write covered call options
on portfolio securities and the U.S. dollar and foreign currencies, without
limit, in order to aid in achieving its investment objective. 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 securities (currency) deliverable under the call option. A call option is
also covered if the Fund holds a call on the same security (currency) 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 achieve a greater total return than would be
realized from holding the underlying securities (currency) alone. Moreover, the
income received from the premium will offset a portion of the potential loss
incurred by the Fund if the securities
 
                                       18
<PAGE>
(currency) 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 less 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. Also, effecting a closing purchase transaction will
permit the cash or proceeds from the concurrent sale of any securities subject
to the option to be used for other investments by the Fund. 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 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 on the option less the commission paid.
 
    Options written by a Fund normally have expiration dates of from up to nine
months (equity securities) to eighteen months (fixed-income securities) 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 (currency) at the time
the option is written. See "Risks of Options and Futures Transactions," below.
 
    COVERED PUT WRITING.  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 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 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 at its Custodian. In writing puts,
the Fund assumes the risk of loss should the market value of the underlying
security 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
 
                                       19
<PAGE>
against delivery of the underlying security. 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 two purposes: (1) to receive the income
derived from the premiums paid by purchasers; and (2) when the Investment
Manager wishes to purchase the security 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. 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
difference between the exercise price of the option and the current market price
of the underlying securities when the put is exercised, offset by the premium
received (less the commissions paid on the transaction).
 
    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 (currency) 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
sold. Any 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.
 
    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 call options 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. 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 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 and currencies (or related
currencies) which it holds (or has the right to acquire) in its portfolio only
to protect itself against a decline in the value of the security (currency). 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. Any 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.  The successful use of options depends on the
ability of the Investment Manager to forecast correctly interest rates and
market movements. 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. 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 currency in which it is denominated) increase, but has retained
the risk of loss should the price of the underlying security (currency) decline.
The covered put writer also retains the risk of loss should the market value of
the underlying security (currency) decline below the exercise price of the
option less the premium
 
                                       20
<PAGE>
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 (currency) 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 over-the-counter 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 (exchange) an underlying security
(currency) at a time when it might otherwise be advantageous to do so. A covered
put option writer who is unable to effect a closing purchase transaction or to
purchase an offsetting over-the-counter option would continue to bear the risk
of decline in the market price of the underlying security (currency) until the
option expires or is exercised. In addition, a covered 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.
 
    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
(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
exercisable in accordance with their terms.
 
    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.
 
    In the event of the bankruptcy of a broker through which the Fund engages in
transactions in options, 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
 
                                       21
<PAGE>
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.
 
    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 which may arise in employing futures contracts to protect against
the price volatility of portfolio securities 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. 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.
 
    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.
 
    STOCK INDEX OPTIONS.  Options on stock indexes are similar to options on
stock except that, rather than the right to take or make delivery of stock at a
specified price, an option on a stock index gives the holder the right to
receive, upon exercise of the option, an amount of cash if the closing level of
the stock index upon which the option is based is greater than, in the case of a
call, or less than, in the case of a put, the exercise price of the option. This
amount of cash is equal to such difference between the closing price of the
index and the exercise price of the option expressed in dollars times a
specified multiple (the "multiplier"). The multiplier for an index option
performs a function similar to the unit of trading for a stock option. It
determines the total dollar value per contract of each point in the difference
between the exercise price of an option and the current level of the underlying
index. A multiplier of 100 means that a one-point difference will yield $100.
Options on different indexes may have different multipliers. The writer of the
option is obligated, in return for the premium received, to make delivery of
this amount. Unlike stock options, all settlements are in cash and a gain or
loss depends on price movements in the stock market generally (or in a
particular segment of the market) rather than the price movements in individual
stocks. Currently, options are traded on the S&P 100 Index and the S&P 500 Index
on the Chicago Board Options Exchange, the Major Market Index and the Computer
Technology Index, Oil Index and Institutional Index on the American Stock
Exchange and the NYSE Index and NYSE Beta Index on the New York Stock Exchange,
The Financial News Composite Index on the Pacific Stock Exchange and the Value
Line Index, National O-T-C Index and Utilities Index on the Philadelphia Stock
Exchange, each of which and any similar index on which options are traded in the
future which include stocks that are not limited to any particular industry or
segment of the market is referred to as a "broadly based stock market index."
Options on stock indexes provide the Fund with a means of protecting the Fund
against the risk of market wide price movements. If the Investment Manager
anticipates a market decline, the Fund could purchase a stock index put option.
If the expected market decline materialized, the resulting decrease in the value
of the Fund's portfolio would be offset to the extent of the increase in the
value of the put option. If the Investment Manager anticipates a market rise,
the Fund may purchase a stock index call option to enable the Fund to
participate in such rise until completion of anticipated
 
                                       22
<PAGE>
common stock purchases by the Fund. Purchases and sales of stock index options
also enable the Investment Manager to more speedily achieve changes in the
Fund's equity positions.
 
    The Fund will write put options on stock indexes only if such positions are
covered by cash, U.S. Government securities or other liquid portfolio securities
equal to the aggregate exercise price of the puts, which cover is held for the
Fund in a segregated account maintained for it by the Fund's Custodian. All call
options on stock indexes written by the Fund will be covered either by a
portfolio of stocks substantially replicating the movement of the index
underlying the call option or by holding a separate call option on the same
stock index with a strike price no higher than the strike price of the call
option sold by the Fund.
 
    RISKS OF OPTIONS ON INDEXES.  Because exercises of stock index options are
settled in cash, call writers such as the Fund cannot provide in advance for
their potential settlement obligations by acquiring and holding the underlying
securities. A call writer can offset some of the risk of its writing position by
holding a diversified portfolio of stocks similar to those on which the
underlying index is based. However, most investors cannot, as a practical
matter, acquire and hold a portfolio containing exactly the same stocks as the
underlying index, and, as a result, bear a risk that the value of the securities
held will vary from the value of the index. Even if an index call writer could
assemble a stock portfolio that exactly reproduced the composition of the
underlying index, the writer still would not be fully covered from a risk
standpoint because of the "timing risk" inherent in writing index options. When
an index option is exercised, the amount of cash that the holder is entitled to
receive is determined by the difference between the exercise price and the
closing index level on the date when the option is exercised. As with other
kinds of options, the writer will not learn that it has been assigned until the
next business day, at the earliest. The time lag between exercise and notice of
assignment poses no risk for the writer of a covered call on a specific
underlying security, such as a common stock, because there the writer's
obligation is to deliver the underlying security, not to pay its value as of a
fixed time in the past. So long as the writer already owns the underlying
security, it can satisfy its settlement obligations by simply delivering it, and
the risk that its value may have declined since the exercise date is borne by
the exercising holder. In contrast, even if the writer of an index call holds
stocks that exactly match the composition of the underlying index, it will not
be able to satisfy its assignment obligations by delivering those stocks against
payment of the exercise price. Instead, it will be required to pay cash in an
amount based on the closing index value on the exercise date; and by the time it
learns that it has been assigned, the index may have declined, with a
corresponding decrease in the value of its stock portfolio. This "timing risk"
is an inherent limitation on the ability of index call writers to cover their
risk exposure by holding stock positions.
 
    A holder of an index option who exercises it before the closing index value
for that day is available runs the risk that the level of the underlying index
may subsequently change. If such a change causes the exercised option to fall
out-of-the-money, the exercising holder will be required to pay the difference
between the closing index value and the exercise price of the option (times the
applicable multiplier) to the assigned writer.
 
    If dissemination of the current level of an underlying index is interrupted,
or if trading is interrupted in stocks accounting for a substantial portion of
the value of an index, the trading of options on that index will ordinarily be
halted. If the trading of options on an underlying index is halted, an exchange
may impose restrictions prohibiting the exercise of such options.
 
    FUTURES CONTRACTS.  The Fund may purchase and sell interest rate and stock
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 ("interest rate" futures), on the U.S. dollar and foreign
currencies, and such indexes as the S&P 500 Index, the Moody's Investment-Grade
Corporate Bond Index and the New York Stock Exchange Composite 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
 
                                       23
<PAGE>
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 and bond
index futures contracts for the purpose of hedging its fixed-income portfolio
(or anticipated portfolio) securities against changes in prevailing interest
rates. If the Investment Manager anticipates that interest rates may rise and,
concomitantly, the price of fixed-income securities fall, the Fund may sell an
interest rate futures contract or a bond index futures contract. If declining
interest rates are anticipated, 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.
 
    The Fund will purchase or sell futures contracts on the U.S. dollar and on
foreign currencies to hedge against an anticipated rise or decline in the value
of the U.S. dollar or foreign currency in which a portfolio security of the Fund
is denominated vis-a-vis another currency.
 
    The Fund will purchase or sell stock index futures contracts for the purpose
of hedging its equity portfolio (or anticipated portfolio) securities against
changes in their prices. If the Investment Manager anticipates that the prices
of stock held by the Fund may fall, the Fund may sell a stock index futures
contract. Conversely, if the Investment Manager wishes to hedge against
anticipated price rises in those stocks which the Fund intends to purchase, the
Fund may purchase stock index futures contracts. In addition, interest rate and
stock index futures contracts will be bought or sold in order to close out a
short or long position in a corresponding futures contract.
 
    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. Index futures
contracts provide for the delivery of an amount of cash equal to a specified
dollar amount times the difference between the stock index value at the open or
close of the last trading day of the contract and the futures contract price. A
futures contract sale is closed out by effecting a futures contract purchase for
the same aggregate amount of the specific type of equity security 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 equity security and the same delivery date. If the offsetting 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 2% 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 called "variation margin," with
the Fund's Custodian, in the account in the name of the broker, which are
reflective of price fluctuations in the futures contract. Currently, interest
rates 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.
 
                                       24

    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 in its foreign currency transactions and hedging strategy. Currently,
currency futures exist for, among other foreign currencies, the Japanese yen,
German mark, Canadian dollar, 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 of
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 currency in
accordance with any U.S. or foreign restrictions or regulations 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.
 
    INDEX FUTURES CONTRACTS.  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.
 
    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 requirement is approximately 5% 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 a gain.
 
    Currently, index futures contracts can be purchased or sold with respect to,
among others, the Standard & Poor's 500 Stock Price Index and the Standard &
Poor's 100 Stock Price Index on the Chicago Mercantile Exchange, the New York
Stock Exchange Composite Index on the New York Futures Exchange, the Major
Market Index on the American Stock Exchange, the Moody's Investment-Grade
Corporate Bond Index on the Chicago Board of Trade and the Value Line Stock
Index on the Kansas City Board of Trade.
 
    OPTIONS ON FUTURES CONTRACTS.  The Fund may purchase and write call and put
options on futures contracts 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), and the writer
the obligation, to assume a position in a futures contract (a long position if
the option is a
 
                                       25
<PAGE>
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
in accordance with the limitation described above. If the CFTC changes its
regulations so that the Fund would be permitted more latitude 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.  The
successful use of futures and related options depends on the ability of the
Investment Manager to accurately predict market, interest rate and currency
movements. 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 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 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.
 
                                       26
<PAGE>
    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.
 
    If the Fund maintains a short position in a futures contract or has sold a
call option on 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 underlying
the futures contract or the exercise price of the option. Such a position may
also be covered by owning the securities underlying the futures contract (in the
case of a stock index futures contract a portfolio of securities substantially
replicating the relevant index), or by holding a call option permitting the Fund
to purchase the same contract at a price no higher than the price at which the
short position was established.
 
    Exchanges may limit the amount by which the price of 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. In the event of adverse price movements, the Fund would
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 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.
 
    The extent to which the Fund may enter into transactions involving options
and futures contracts 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 and
the Statement of Additional Information.
 
    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 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 (a) temporarily, by short-term traders seeking to profit
from the difference between a contract or security price objective and their
cost of borrowed funds; (b) by investors in futures contracts electing to close
out their contracts through offsetting transactions rather than meet margin
deposit requirements; (c) by investors in futures contracts opting to make or
take delivery of underlying securities rather than engage in closing
transactions, thereby reducing liquidity of the futures market; and (d)
temporarily, by speculators who view the deposit requirements in the futures
markets as less onerous than margin requirements in the cash market. Due to the
possibility
 
                                       27
<PAGE>
of price distortion 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 may
still not result in a successful hedging transaction.
 
    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 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 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 at a time when it may be
disadvantageous to do so.
 
    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.
 
    The Investment Manager has 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.
 
    NEW INSTRUMENTS.  New futures contracts, options and other financial
products and various combinations thereof continue to be developed. The Fund may
invest in any such futures, options or products as may be developed, to the
extent consistent with its investment objective and applicable regulatory
requirements.
 
PORTFOLIO TURNOVER
 
    It is anticipated that the Fund's portfolio turnover rate will not exceed
100%. A 100% turnover rate would occur, for example, if 100% 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%
 
                                       28
<PAGE>
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. 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.
 
         2. 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.
 
         3. Borrow money, except that the Fund may borrow from a bank for
    temporary or emergency purposes in amounts not exceeding 5% (taken at the
    lower of cost or current value) of its total assets (not including the
    amount borrowed).
 
         4. Pledge its assets or assign or otherwise encumber them except to
    secure borrowings effected within the limitations set forth in restriction
    (3). 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. 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.
 
         6. 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 objective and policies; (b) by investment in
    repurchase agreements; or (c) by lending its portfolio securities.
 
         7. Make short sales of securities.
 
         8. 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.
 
         9. 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.
 
        10. Invest for the purpose of exercising control or management of any
    other issuer.
 
        11. Purchase securities of other investment companies, except in
    connection with a merger, consolidation, reorganization or acquisition of
    assets or in accordance with the provisions of Section 12(d) of the Act and
    any Rules promulgated thereunder.
 
        12. Purchase or sell commodities or commodities contracts except that
    the Fund may purchase or sell futures contracts or options on futures.
 
    In addition, as a nonfundamental policy, the Fund may not 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.
 
                                       29
<PAGE>
   
    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.
    
 
    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.
 
PORTFOLIO TRANSACTIONS AND BROKERAGE
- --------------------------------------------------------------------------------
 
    Subject to the general supervision of the 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. 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.
 
   
    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 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, and 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 foreign 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
 
                                       30
<PAGE>
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 period from commencement of operations (May 31, 1994)
through February 28, 1995, and the fiscal years ended February 29, 1996, and
February 28, 1997, the Fund paid $579,923, $497,963 and $242,887, respectively,
in brokerage commissions.
 
    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. During the fiscal year ended February 28, 1997, the Fund directed
the payment of $232,875 in brokerage commissions in connection with transactions
in the aggregate amount of $92,139,345 to brokers because of research services
provided.
 
    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 or 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 broker in a commensurate arm's-length transaction.
Furthermore, the Board of 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 the affiliated broker or dealer
are consistent with the foregoing standard. The Fund does not reduce the
management fee it pays to the Investment Manager by any amount of the brokerage
commissions it may pay to an affiliated broker or dealer. During the period
ended February 28, 1995 and the fiscal years ended February 29, 1996 and
February 28, 1997, the Fund paid a total of $36,000, $28,405 and $6,236,
respectively, in brokerage commissions to DWR. During the fiscal year ended
February 28, 1997, the brokerage commissions paid to DWR represented
approximately 2.57% of the total brokerage commissions paid by the Fund during
the fiscal year and were paid on account of transactions having an aggregate
dollar value equal to approximately 4.23% of the aggregate dollar value of all
portfolio transactions of the Fund during the period for which commissions were
paid.
    
 
   
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
dealer agreement with DWR, which through its own sales organization sells shares
of the Fund. In addition, the Distributor may enter into similar agreements with
other selected dealers ("Selected Broker-Dealers"). The Distributor, a Delaware
corporation, is a
 
                                       31
<PAGE>
   
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 (the "Distribution Agreement") appointing the Distributor exclusive
distributor of the Fund's shares and providing for the Distributor to bear
distribution expenses not borne by the Fund. By its terms, the Distribution
Agreement has an initial term ending April 30, 1998, and provides that it will
remain in effect from year to year thereafter if approved by the Board.
    
 
   
    The Distributor bears all expenses it may incur in providing services under
the Distribution Agreement. Such expenses include the payment of commissions for
sales of the Fund's shares and incentive compensation to account executives. The
Distributor also pays certain expenses in connection with the distribution of
the Fund's shares, including the costs of preparing, printing and distributing
advertising or promotional materials, and the costs of printing and distributing
prospectuses and supplements thereto used in connection with the offering and
sale of the Fund's shares. The Fund bears the costs of initial typesetting,
printing and distribution of prospectuses and supplements thereto to
shareholders. The Fund also bears the costs of registering the Fund and its
shares under federal 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 1.0% of the average daily net assets of Class A and
Class C, respectively, and, with respect to Class B, 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 (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 received
approximately $487,000, $1,102,431 and $801,650, in contingent deferred sales
charges for the period May 31, 1994 through February 28, 1995 and the fiscal
years ended February 29, 1996 and February 28, 1997, respectively, none of which
was retained by the Distributor.
    
 
   
    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 0.25% of such Class's average daily net assets 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 vote of the Trustees of the Fund on December 2,
1993, at a meeting of the Trustees called for the purpose of voting on such
Plan. The vote included the vote of a majority 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"). In making their decision to adopt the Plan, the
Trustees requested from the Distributor and received such information as they
deemed necessary to make an informed determination as to whether or not adoption
 
                                       32
<PAGE>
of the Plan was in the best interests of the shareholders of the Fund. After due
consideration of the information received, the Trustees, including the
Independent 12b-1 Trustees, determined that adoption of the Plan would benefit
the shareholders of the Fund. InterCapital, as sole shareholder of the Fund,
approved the Plan on February 24, 1994, whereupon the Plan went into effect.
 
    Under its terms, the Plan will remain in effect from year to year, provided
such continuance is approved annually by a vote of the Trustees in the manner
described above. Under the Plan and as required by Rule 12b-1, the Trustees will
receive and review promptly after the end of each fiscal 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.
 
   
    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 Trustees of the Fund,
including a majority of the Independent 12b-1 Trustees, at their meeting held on
April 24, 1997. Prior to approving the continuation of the Plan, the Trustees
requested and received from the Distributor and reviewed all the information
which they deemed necessary to arrive at an informed determination. In making
their determination to continue the Plan, the Trustees considered: (1) the
Fund's experience under the Plan and whether such experience indicates that the
Plan is operating as anticipated; (2) the benefits the Fund had obtained, was
obtaining and would be likely to obtain under the Plan; and (3) what services
had been provided and were continuing to be provided under the Plan by the
Distributor 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. 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 will receive and
review promptly after the end of each fiscal 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 $2,230,263,
$3,341,620 and $3,227,912, respectively, payable to the Distributor pursuant to
the Plan, for the period ended February 28, 1995 and the fiscal years ended
February 29, 1996 and February 28, 1997. This is an accrual at an annual rate of
0.95% of the average daily aggregate gross sales of the Fund's 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
shares redeemed since the Fund's inception upon which a contingent deferred
sales charge has been imposed or waived. This amount is treated by the Fund as
an expense in the year it is accrued.
 
   
    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 5.0% of the
amount sold (except as provided in the following sentence) and an annual
residual commission, currently a residual of up to 0.25% 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 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 5.0% of the
    
 
                                       33
<PAGE>
   
amount sold (except as provided in the following sentence) and an annual
residual commission, currently a residual of up to 0.25% 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 1.0% 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 Fund associated distribution-related expenses,
including sales compensation and overhead. The distribution fee that the
Distributor receives from the Fund under the Plan, in effect, offsets
distribution expenses incurred 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 sales 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 term "overhead and other branch office distribution-related expenses"
represents (a) the expenses of operating DWR's branch offices 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 share sales.
    
 
   
    The Fund paid 100% of the $3,227,912 accrued under the Plan for the fiscal
year ended February 28, 1997, to the Distributor. The Distributor and DWR
estimate that they have spent, pursuant to the Plan, $22,546,836 on behalf of
the Fund since the inception of the Plan. It is estimated that this amount was
spent in approximately the following ways: (i) 7.04% ($1,587,048) -- advertising
and promotional expenses; (ii) 1.05% ($236,994) -- printing of prospectuses for
distribution to other than current shareholders; and (iii) 91.91% ($20,722,794)
- -- other expenses, including the gross sales credit and the carrying charge, of
which 7.99% ($1,654,760) represents carrying charges, 36.74% ($7,613,866)
represents commission credits to DWR branch offices for payments of commissions
to account executives and 55.27% ($11,454,168) 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.
    
 
                                       34
<PAGE>
   
    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 1.0%, 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 in 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 shares, totalled
$11,326,626 as of February 28, 1997, which amount constitutes 3.22% of the
Fund's net assets on such date. 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 distribution expenses in excess of
payments made 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 or indirect
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.
 
   
    The Plan may not be amended to increase materially the amount to be spent
for the services described therein without approval of the shareholders of the
affected Class or Classes of the Fund, and all material amendments of 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 Trustees shall be
committed to the discretion of the Independent Trustees.

DETERMINATION OF NET ASSET VALUE
- --------------------------------------------------------------------------------
 
   
    As stated in the Prospectus, the net asset value per share for each Class of
shares of the Fund 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 and dividing by the number of shares outstanding and
adjusting to the nearest cent. 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.
    
 
   
    As stated in the Prospectus, short-term securities with remaining maturities
of 60 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 60
days, whereupon they will be valued at amortized cost using their value on the
61st day unless the Trustees determine such does not reflect the securities'
market value, in which case these securities will be valued at their fair value
as determined by the Trustees. Listed options on debt securities are valued at
the latest sale price on the exchange on which they are listed unless no sales
of such options have taken place that day, in which case they will be valued at
the mean between their latest bid and asked prices. Unlisted options on debt
securities and all options on equity securities 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
that such price does not reflect their market value, in which case they will be
valued at their fair value as determined by the Trustees. All other securities
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.
    
 
    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 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.
 
   
PURCHASE OF FUND SHARES
    
- --------------------------------------------------------------------------------
 
   
    As discussed in the Prospectus, the Fund offers four Classes of shares as
follows:
    
 
   
INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES
    
 
   
    Class A shares are sold to investors with an initial sales charge that
declines to zero for larger purchases; however, Class A shares sold without an
initial sales charge are subject to a contingent deferred sales charge ("CDSC")
of 1.0% if redeemed within one year of purchase, except in the circumstances
discussed in the Prospectus.
    
 
   
    RIGHT OF ACCUMULATION.  As discussed in the Prospectus, investors may
combine the current value of shares purchased in separate transactions for
purposes of benefitting from the reduced sales charges available for purchases
of shares of the Fund totalling at least $25,000 in net asset value. For
example, if any person or entity who qualifies for this privilege holds Class A
shares of the Fund and/or other Dean Witter Funds that are multiple class funds
("Dean Witter Multi-Class Funds") or shares of other Dean Witter Funds sold with
a front-end sales charge purchased at a price including a front-end sales charge
having a current value of $5,000, and purchases $20,000 of additional shares of
the Fund, the sales charge applicable to the $20,000 purchase would be 4.75% of
the offering price.
    
 
                                       36
<PAGE>
   
    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.
    
 
   
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
    
 
                                       37
<PAGE>
   
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:

    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 charge, 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 the Distributor, which 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 open-end Dean Witter Fund
other than Dean Witter Global Utilities Fund or in another Class of Dean Witter
Global Utilities Fund. Such investment will be made as described above for
automatic investment in shares of the applicable Class of the Fund, at the net
asset value per share of the 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.
Shareholders of Dean Witter Global Utilities 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
 
                                       39
<PAGE>
   
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 the net asset value next determined after receipt by the
Transfer Agent, without the imposition of a CDSC upon redemption, by returning
the check or the proceeds to the Transfer Agent within thirty days after the
payment date. If the shareholder returns the proceeds of a dividend or
distribution, such funds must be accompanied by a signed statement indicating
that the proceeds constitute a dividend or distribution to be invested. Such
investment will be made at the net asset value per share next determined after
receipt of the check or proceeds by the Transfer Agent.
    
 
   
    SYSTEMATIC WITHDRAWAL PLAN.  As discussed in the Prospectus, a systematic
withdrawal plan (the "Withdrawal Plan") is available for shareholders who own or
purchase shares of the Fund having a minimum value of $10,000 based upon the
then current net asset value. The Withdrawal Plan provides for monthly or
quarterly (March, June, September and December) checks in any dollar amount, not
less than $25, or in any whole percentage of the account balance, on an
annualized basis. Any applicable CDSC will be imposed on shares redeemed under
the Withdrawal Plan (see "Purchase of Fund 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 an 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").
    
 
    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 nomination to the Transfer Agent. In
addition, the party and/or the address to which the 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
share-
 
                                       40
<PAGE>
holder 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 Global Utilities Fund, and indicating the
selected Class, directly to the Fund's Transfer Agent. In the case of Class A
shares, after deduction of any applicable sales charge, the balance will be
applied to the purchase of Fund shares, and, in the case of shares of the other
Classes, the entire amount will be applied to the purchase of Fund shares, at
the net asset value per share next computed after receipt of the check or
purchase payment by the Transfer Agent. The shares so purchased will be credited
to the investor's account.
    
 
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 caption "Purchase of
Fund Shares," a CDSC may be imposed upon a redemption, depending on a number of
factors, including the number of years from the time of purchase until the time
of redemption or exchange ("holding period"). When shares of a Dean Witter
Multi-Class Fund or 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 the last day of the
month in which the Exchange Fund shares were acquired), the holding period or
"year since purchase payment made" is frozen. When shares are redeemed out of
the Exchange Fund, they will be subject to a CDSC which would be based upon the
period of time the shareholder held shares in a Dean Witter Multi-Class Fund or
in a CDSC 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, if any, incurred
on or after that date which are attributable to those shares. Shareholders
acquiring shares of an Exchange Fund pursuant to this exchange privilege may
exchange those shares back into a Dean Witter Multi-Class Fund or a CDSC Fund
from the Exchange Fund, with no CDSC being imposed on such exchange. The holding
period previously frozen
    
 
                                       41
<PAGE>
   
when shares were first exchanged for shares of the Exchange Fund resumes on the
last day of the month in which shares of a Dean Witter Multi-Class Fund or of 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 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 for shares of an Exchange Fund, the date
of purchase of the shares of the fund exchanged into, for purposes of the CDSC
upon redemption, will be the last day of the month in which the shares being
exchanged were originally purchased. In allocating the purchase payments between
funds for purposes of the CDSC, the amount which represents the current net
asset value of shares at the time of the exchange which were (i) purchased more
than one, three or six years (depending on the CDSC schedule applicable to the
shares) prior to the exchange, (ii) originally acquired through reinvestment of
dividends or distributions and (iii) acquired in exchange for shares of FSC
Funds, or for shares of other Dean Witter Funds for which shares of FSC Funds
have been exchanged (all such shares called "Free Shares"), will be exchanged
first. After an exchange, all dividends earned on shares in an Exchange Fund
will be considered Free Shares. If the exchanged amount exceeds the value of
such Free Shares, an exchange is made, on a block-by-block basis, of non-Free
Shares held for the longest period of time (except that, with respect to Class B
shares, if shares held for identical periods of time but subject to different
CDSC schedules are held in the same Exchange Privilege account, the shares of
that block that are subject to a lower CDSC rate will be exchanged prior to the
shares of that block that are subject to a higher CDSC rate). Shares equal to
any appreciation in the value of non-Free Shares exchanged will be treated as
Free Shares, and the amount of the purchase payments for the non-Free Shares of
the fund exchanged into will be equal to the lesser of (a) the purchase payments
for, or (b) the current net asset value of, the exchanged non-Free Shares. If an
exchange between funds would result in exchange of only part of a particular
block of non-Free Shares, then shares equal to any appreciation in the value of
the block (up to the amount of the exchange) will be treated as Free Shares and
exchanged first, and the 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.
    
 
    The Transfer Agent acts as agent for shareholders of the Fund in effecting
redemptions of Fund shares and in applying the proceeds to the purchase of other
fund shares. In the absence of negligence on its part, neither the Transfer
Agent nor the Fund shall be liable for any redemption of Fund shares caused by
unauthorized telephone instructions. Accordingly, in such an event the investor
shall bear the risk of loss. The staff of the Securities and Exchange Commission
is currently considering the propriety of such a policy.
 
    With respect to the redemption or repurchase of shares of the Fund, the
application of proceeds to the purchase of new shares in the Fund or any other
of the funds and the general administration of the Exchange Privilege, the
Transfer Agent acts as agent for the Distributor and for the shareholder's
selected broker-dealer, if any, in the performance of such functions. With
respect to exchanges, redemptions or repurchases, the Transfer Agent shall be
liable for its own negligence and not for the default or negligence of its
correspondents or for losses in transit. The Fund shall not be liable for any
default or negligence of the Transfer Agent, the Distributor or any selected
broker-dealer.
 
                                       42
<PAGE>
    The Distributor and any selected broker-dealer have authorized and appointed
the Transfer Agent to act as their agent in connection with the application of
proceeds of any redemption of Fund shares to the purchase of shares of any other
fund and the general administration of the Exchange Privilege. No commission or
discounts will be paid to the Distributor or any selected broker-dealer for any
transactions pursuant to this Exchange Privilege.
 
   
    Exchanges are subject to the minimum investment requirement and any other
conditions imposed by each fund. (The minimum initial investment for the
Exchange Privilege account of each Class is $5,000 for Dean Witter Liquid Asset
Fund Inc., Dean Witter Tax-Free Daily Income Trust, Dean Witter California
Tax-Free Daily Income Trust and Dean Witter New York Municipal Money Market
Trust, although those funds may, at their discretion, accept initial investments
of as low as $1,000. The minimum investment for the Exchange Privilege account
of each Class is $10,000 for Dean Witter Short-Term U.S. Treasury Trust,
although that fund, in its discretion, may accept initial purchases as low as
$5,000. The minimum initial investment for the Exchange Privilege account of
each Class for Dean Witter Special Value Fund is $5,000. 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
Exchange Funds, pursuant to the Exchange Privilege, and provided further that
the Exchange Privilege may be terminated or materially revised without notice at
times (a) when the New York Stock Exchange is closed for other than customary
weekends and holidays, (b) when trading on that Exchange is restricted, (c) when
an emergency exists as a result of which disposal by the Fund of securities
owned by it is not reasonably practicable or it is not reasonably practicable
for the Fund fairly to determine the value of its net assets, (d) during any
other period when the Securities and Exchange Commission by order so permits
(provided that applicable rules and regulations of the Securities and Exchange
Commission shall govern as to whether the conditions prescribed in (b) or (c)
exist) or (e) if the Fund would be unable to invest amounts effectively in
accordance with its investment objective, policies and restrictions.
 
    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. 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.
 
    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 (see below). 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
    
 
                                       43
<PAGE>
   
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 accompanied by a share certificates, 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
acceptance 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. 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 a 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 any Class of 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. 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 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 certified
check or bank cashier 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.
    
 
   
    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
    
 
                                       44
<PAGE>
   
transfer). The transferred shares will continue to be subject to any applicable
CDSC as if they had not been so transferred.
    
 
   
    REINSTATEMENT PRIVILEGE.  As discussed in the Prospectus, a shareholder who
has had his or her shares redeemed or repurchased and has not previously
exercised this reinstatement privilege may, within 35 days after the redemption
or repurchase, reinstate any portion or all of the proceeds of such redemption
or repurchase in shares of the Fund in the same Class held by the shareholder at
the net asset value next determined after a reinstatement request, together with
the proceeds, is received by the Transfer Agent.
    
 
    Exercise of the reinstatement privilege will not affect the federal income
tax and state 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 and state personal 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.
 
    Any dividends declared in the last quarter of any calendar year which are
paid in the following calendar year prior to February 1 will be deemed received
by the shareholder in the prior calendar year.
 
    Gains or losses on sales of securities by the Fund will generally 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 generally short-term capital gains or losses.
 
    The Fund intends 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. In addition, the
Fund intends to distribute to its shareholders each calendar year a sufficient
amount of ordinary income and capital gains to avoid the imposition of a 4%
excise tax.
 
    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, the portion
taxable as long-term capital gains, and the amount of dividends eligible for the
Federal dividends received deduction available to corporations. 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.
 
    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.
 
                                       45
<PAGE>
    The Fund may elect to retain net capital gains and pay corporate income tax
thereon. In such event, each shareholder of record on the last day of the Fund's
taxable year would be required to include in income for tax purposes such
shareholder's proportionate share of the Fund's undistributed net capital gain.
In addition, each shareholder would be entitled to credit such shareholder's
proportionate share of the tax paid by the Fund against federal income tax
liabilities, to claim refunds to the extent that the credit exceeds such
liabilities, and to increase the basis of his shares held for federal income tax
purposes by an amount equal to 65% of such shareholder's proportionate share of
the undistributed net capital gain.
 
    Any loss realized by shareholders upon a redemption of shares within six
months of the date of their purchase will be treated as a long-term capital loss
to the extent of any distributions of net long-term capital gains during the
six-month period.
 
    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 or
deductions 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 rata portions in computing their taxable income 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 are currently considered to 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 certain foreign currency instruments 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 or losses derived with respect to foreign fixed-income
securities are also subject to Section 988 treatment. In general, therefore,
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.
 
    If the Fund invests in an entity which is classified as a "passive foreign
investment company" ("PFIC") for U.S. tax purposes, the application of certain
technical tax provisions applying to such companies could result in the
imposition of federal income tax with respect to such investments at the Fund
level which could not be eliminated by distributions to shareholders. In any
event, it is not anticipated that any taxes on the Fund with respect to
investments in PFIC's would be significant.
 
    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
"total return" in advertisements and sales literature. These figures are
computed separately for Class A, Class B, Class C and Class D shares. 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 total return of the Fund for the fiscal year ended February 28, 1997 and
for the period from May 31, 1994 (commencement of the Fund's operations) through
February 28, 1997 was 7.91% and 9.99%, respectively. These returns are for Class
B only; there were no other Classes of shares outstanding on such date.
    
 
   
    In addition to the foregoing, the Fund may advertise its total return over
for each Class 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 returns of the Fund may be calculated in the manner described above, but
without deduction for any applicable contingent deferred sales charge. Based
upon this calculation, the average annual total return of the Fund for the
fiscal year ended February 28, 1997 and for the period May 31, 1994
(commencement of operations) through February 28, 1997 was 12.91% and 10.91%,
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 February 28, 1997
and for the period May 31, 1994 (commencement of operations) through February
28, 1997 was 12.91% and 32.93%, respectively. 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 total aggregate total return to date (expressed as a decimal and
without taking into account the effect of applicable CDSC) and multiplying by
$9,475, $48,000 and $97,000 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 $13,293, $66,465 and $132,930, respectively, at
February 28, 1997. 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 to remove the Trustees following a meeting
called for that purpose requested in writing by the record holders of not less
than ten percent of the Fund's outstanding shares. The voting rights of
shareholders are not cumulative, so that holders of more than 50 percent of the
shares voting can, if they choose, elect all Trustees being selected, while the
holders of the remaining shares would be unable to elect any Trustees.
    
 
   
    The Declaration of Trust permits the Trustees to authorize the creation of
additional series of shares (the proceeds of which would be invested in
separate, independently managed portfolios) and additional classes of shares
within any series. The Trustees have not presently authorized any such
additional series or classes of shares other than as set forth in the
Prospectus.
    
 
    The Declaration of Trust provides that no Trustee, officer, employee or
agent of the Fund is liable to the Fund or to a shareholder, nor is any Trustee,
officer, employee or agent liable to any third persons in connection with the
affairs of the Fund, except as such liability may arise from his or her own bad
faith, willful misfeasance, gross negligence, or reckless disregard of his or
her 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.
 
    The Fund is authorized to issue an unlimited number of shares of beneficial
interest. The Fund shall be of unlimited duration subject to the provisions in
the Declaration of Trust concerning termination by action of the shareholders.

DEAN WITTER GLOBAL UTILITIES FUND
REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND TRUSTEES
OF DEAN WITTER GLOBAL UTILITIES FUND
 
In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Dean Witter Global Utilities Fund
(the "Fund") at February 28, 1997, the results of its operations for the year
then ended, the changes in its net assets for each of the two years in the
period then ended and the financial highlights for each of the two years in the
period then ended and for the period May 31, 1994 (commencement of operations)
through February 28, 1995, 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 February 28, 1997 by correspondence with the
custodian and brokers, provide a reasonable basis for the opinion expressed
above.

1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter Global Utilities Fund (the "Fund") is registered under the
Investment Company Act of 1940, as amended (the "Act"), as a diversified,
open-end management investment company. The Fund's investment objective is to
seek both capital appreciation and current income. The Fund seeks to achieve its
objective by investing in equity and fixed income securities of companies,
issued by issuers worldwide, which are engaged in the utilities industry. The
Fund was organized as a Massachusetts business trust on October 22, 1993 and
commenced operations on May 31, 1994.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual results could differ from
those estimates.
 
The following is a summary of significant accounting policies:
 
A. VALUATION OF INVESTMENTS -- (1) an equity security listed or traded on the
New York, American 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); (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; (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; (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.
Dividend income and other distributions are recorded on the ex-dividend date
except for certain dividends on foreign securities which are recorded as soon as
the Fund is informed after the ex-dividend date. Discounts are accreted over the
life of the respective securities. Interest income is accrued daily.
 
C. 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.
 
D. 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 and in the Statement of
Assets and Liabilities as part of the related foreign currency denominated asset
or liability. 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.
 
E. 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.
 
F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends and
distributions to its shareholders on the ex-dividend 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

NOTES TO FINANCIAL STATEMENTS FEBRUARY 28, 1997, CONTINUED
 
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.
 
G. ORGANIZATIONAL EXPENSES -- The Investment Manager paid the organizational
expenses of the Fund in the amount of approximately $174,000 which have been
reimbursed for the full amount thereof. Such expenses have been deferred and are
being amortized on the straight-line method over a period not to exceed five
years from the commencement of operations.
 
2. INVESTMENT MANAGEMENT AGREEMENT
 
Pursuant to an Investment Management Agreement, the Fund pays the Investment
Manager a management fee, accrued daily and payable monthly, by applying the
annual rate of 0.65% to the net assets of the Fund determined as of the close of
each business day.
 
Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes, 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 1.0% of the lesser of: (a) the average
daily aggregate gross sales of the Fund's shares since the inception of the Fund
(not including reinvestment of dividend or capital gain distributions) less the
average daily aggregate net asset value of the 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, the account executives of Dean
Witter Reynolds Inc. ("DWR"), an affiliate of the Investment Manager and
Distributor, and other employees or 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 $11,326,626
at February 28, 1997.
 
The Distributor has informed the Fund that for the year ended February 28, 1997,
it received approximately $802,000 in contingent deferred sales charges from
certain redemptions of the Fund's shares.
 
4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES
 
The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the year ended February 28, 1997 aggregated
$35,728,415 and $70,884,641, respectively.
 
For the year ended February 28, 1997, the Fund incurred brokerage commissions of
$6,236 with DWR for portfolio transactions executed on behalf of the Fund.
 
Dean Witter Trust Company, an affiliate of the Investment Manager and
Distributor, is the Fund's transfer agent. At February 28, 1997, the Fund had
transfer agent fees and expenses payable of approximately $39,000.

6. FEDERAL INCOME TAX STATUS
 
As of February 28, 1997, the Fund had temporary book/tax differences primarily
attributable to capital loss deferrals on wash sales and permanent book/tax
differences primarily attributable to foreign currency losses. To reflect
reclassifications arising from the permanent differences, accumulated
undistributed net investment income was charged and accumulated undistributed
net realized gain was credited $56,746.
 
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 foreign currency exposure associated with foreign currency
denominated securities.
 
Forward contracts involve elements of market risk in excess of the amounts
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 February 28, 1997, there were outstanding forward contracts to facilitate
settlement of foreign currency denominated portfolio transactions.

RATINGS OF CORPORATE DEBT INSTRUMENTS INVESTMENTS
MOODY'S INVESTORS SERVICE INC. ("MOODY'S")
 
                         FIXED-INCOME SECURITY RATINGS
 
<TABLE>
<S>        <C>
Aaa        Fixed-income securities 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         Fixed-income securities 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 fixed-income securities. They are rated lower than the best fixed-income
           securities 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
           other elements present which make the long-term risks appear somewhat larger than
           in Aaa securities.
A          Fixed-income securities 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        Fixed-income securities 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 fixed-income securities lack outstanding investment
           characteristics and in fact have speculative characteristics as well.
           Fixed-income securities rated Aaa, Aa, A and Baa are considered investment grade.
Ba         Fixed-income securities which are rated Ba are judged to have speculative elements;
           their future cannot be considered as well assured. Often the protection of interest
           and principal payments may be very moderate, and therefore not well safeguarded
           during both good and bad times in the future. Uncertainty of position characterizes
           bonds in this class.
B          Fixed-income securities which are rated B generally lack characteristics of the
           desirable investment. Assurance of interest and principal payments or of
           maintenance of other terms of the contract over any long period of time may be
           small.
Caa        Fixed-income securities 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         Fixed-income securities which are rated Ca present obligations which are
           speculative in a high degree. Such issues are often in default or have other marked
           shortcomings.
C          Fixed-income securities which are rated C are the lowest rated class of fixed
           income securities, and issues so rated can be regarded as having extremely poor
           prospects of ever attaining any real investment standing.
</TABLE>
 
    RATING REFINEMENTS: Moody's may apply numerical modifiers, 1, 2, and 3 in
each generic rating classification from Aa through B in its municipal
fixed-income security 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.

<PAGE>
                            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. The ratings apply to Municipal Commercial Paper as well as taxable
Commercial Paper. Moody's employs the following three designations, all judged
to be investment grade, to indicate the relative repayment capacity of rated
issuers: Prime-1, Prime-2, Prime-3.
 
    Issuers rated Prime-1 have a superior capacity for repayment of short-term
promissory obligations. Issuers rated Prime-2 have a strong capacity for
repayment of short-term promissory obligations; and Issuers rated Prime-3 have
an acceptable capacity for repayment of short-term promissory obligations.
Issuers rated Not Prime do not fall within any of the Prime rating categories.
 
STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S")
 
                         FIXED-INCOME SECURITY RATINGS
 
    A Standard & Poor's fixed-income security 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        Fixed-income securities rated "AAA" have the highest rating assigned by Standard &
           Poor's. Capacity to pay interest and repay principal is extremely strong.
AA         Fixed-income securities rated "AA" have a very strong capacity to pay interest and
           repay principal and differs from the highest-rate issues only in small degree.
A          Fixed-income securities rated "A" have 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 fixed-income securities in
           higher-rated categories.
BBB        Fixed-income securities rated "BBB" are 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 fixed-income
           securities in this category than for fixed-income securities in higher-rated
           categories.
           Fixed-income securities rated AAA, AA, A and BBB are considered investment grade.
BB         Fixed-income securities rated "BB" have less near-term vulnerability to default
           than other speculative grade fixed-income securities. However, it faces major
           ongoing uncertainties or exposures to adverse business, financial or economic
           conditions which could lead to inadequate capacity or willingness to pay interest
           and repay principal.
B          Fixed-income securities rated "B" have a greater vulnerability to default but
           presently have 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.

<TABLE>
<S>        <C>
CCC        Fixed-income securities rated "CCC" have a current identifiable vulnerability to
           default, and are 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, they are not likely to
           have the capacity to pay interest and repay principal.
CC         The rating "CC" is typically applied to fixed-income securities subordinated to
           senior debt which is assigned an actual or implied "CCC" rating.
C          The rating "C" is typically applied to fixed-income securities subordinated to
           senior debt which is assigned an actual or implied "CCC-" rating.
CI         The rating "CI" is reserved for fixed-income securities on which no interest is
           being paid.
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.
           Fixed-income securities rated "BB," "B," "CCC," "CC" and "C" are regarded as having
           predominantly speculative characteristics with respect to capacity to pay interest
           and repay principal. "BB" indicates the least degree of speculation and "C" the
           highest degree of speculation. While such fixed-income securities will likely have
           some quality and protective characteristics, these are outweighed by large
           uncertainties or major risk exposures to adverse conditions.
           Plus (+) or minus (-): The rating from "AA" to "CCC" may be modified by the
           addition of a plus or minus sign to show relative standing with the major ratings
           categories.
</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.
Ratings are applicable to both taxable and tax-exempt commercial paper. The
categories are as follows:
 
    Issues assigned A ratings are regarded as having the greatest capacity for
timely payment. Issues in this category are further refined with the designation
1, 2, and 3 to indicate the relative degree of safety.
 
<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.


                                          2
<PAGE>

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

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

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

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

                     INSTRUMENT ESTABLISHING AND DESIGNATING
                          ADDITIONAL CLASSES OF SHARES


WHEREAS, Dean Witter Global Utilities Fund (the "Trust") was established by the
Declaration of Trust dated October 21, 1993, as amended from time to time (the
"Declaration"), under the laws of the Commonwealth of Massachusetts;

WHEREAS, Section 6.9(h) of the Declaration provides that the establishment and
designation of any additional class of shares shall be effective upon the
execution by a majority of the then Trustees of an instrument setting forth such
establishment and designation and the relative rights, preferences, voting
powers, restrictions, limitations as to dividends, qualifications, and terms and
conditions of such class, or as otherwise provided in such instrument, which
instrument shall have the status of an amendment to the Declaration; and

WHEREAS, the Trustees of the Trust have deemed it advisable to establish and
designate three additional classes of shares and to designate classes for the
existing shares held prior to July 28, 1997 ("Existing Class") as provided
herein.

NOW, THEREFORE, BE IT RESOLVED, pursuant to Section 6.9(h) of the Declaration,
there are hereby established and designated three additional classes of shares,
to be known as:  Class A, Class C and Class D (the "Additional Classes"), each
of which shall be subject to the relative rights, preferences, voting powers,
restrictions, limitations as to dividends, qualifications, and terms and
conditions of redemption set forth in the Declaration with respect to the
Existing Class, except to the extent the DEAN WITTER FUNDS MULTIPLE CLASS PLAN
PURSUANT TO RULE 18f-3 attached hereto as EXHIBIT A sets forth differences (i)
between each of the Additional Classes, or (ii) among each of the Existing Class
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
Trust.

This instrument may be executed in more than one counterpart, each of which
shall be deemed an original, but all of which together shall constitute one and
the same document.

IN WITNESS THEREOF, the undersigned, the Trustees of the Trust, have executed
this instrument this 30th day of June, 1997.

                               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.

    AGREEMENT  made as of the  31st day of May, 1997  by and between Dean Witter

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  facilties  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: 0.65% of daily  net assets up  to
$500  million;  and 0.625%  of daily  net  assets over  $500 million.  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 litigations  costs and  any indemnification related
thereto) paid or 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
 
                                       2
<PAGE>
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 Director,
officer or employee of the Investment Manager to engage in any other business or
to devote his 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,
conflict 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
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
 
                                       3
<PAGE>
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 Global Utilities  
Fund, dated  October 21,  1993, a copy  of which, together  with all amendments

Utilities Fund  refers to  the Trustees  under the  Declaration collectively  as

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 Global Utilities  Fund, but the  Trust Estate only
shall be liable.

                               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.

                             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 GLOBAL UTILITIES FUND

   WHEREAS, Dean Witter Global Utilities Fund (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 amended and restated a Plan of 
Distribution pursuant to Rule 12b-1 under the Act which had initially been 
adopted on February 24, 1994, 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, the Fund and Dean Witter Distributors Inc. (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 February 24, 1994), 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, Dean 
Witter Reynolds Inc. ("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 1.0%, 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 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 


                                        1
<PAGE>


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) 1.0% 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) 1.0% 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 thereby.  It 
is 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 and 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.


                                2
<PAGE>

   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

                               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.
