PROSPECTUS SUMMARY
- --------------------------------------------------------------------------------
 
<TABLE>
<S>             <C>

- -------------------------------------------------------------------------------------------------------
 
OFFERING        At net asset value without sales charge (see page 8). Shares redeemed within six years
PRICE           of purchase are subject to a contingent deferred sales charge under most circumstances
                (see pages 12-13).
- -------------------------------------------------------------------------------------------------------
 
MINIMUM         The minimum initial investment is $1,000 ($100 if the account is opened through
PURCHASE        EasyInvest -SM-) the minimum subsequent investment is $100 (see page 8).
- -------------------------------------------------------------------------------------------------------
 
INVESTMENT      The investment objective of the Fund is to provide current income and long-term growth
OBJECTIVE       of income and capital (see page 5).
- -------------------------------------------------------------------------------------------------------
 
INVESTMENT      Dean Witter InterCapital Inc., the Investment Manager of the Fund, and its wholly-owned
MANAGER         subsidiary, Dean Witter Services Company Inc., serve in various investment management,
                advisory, management and administrative capacities to 102 investment companies and other
                portfolios with assets of approximately $93 billion at February 28, 1997.
- -------------------------------------------------------------------------------------------------------
 
MANAGEMENT FEE  The Investment Manager receives a monthly fee at the annual rate of 0.65% of daily net
                assets up to $500 million, scaled down at various asset levels to 0.425% of the Fund's
                daily net assets on assets exceeding $5 billion (see page 5).
- -------------------------------------------------------------------------------------------------------
 
DIVIDENDS       Dividends from net investment income are declared and paid quarterly. Distributions from
                net short-term and long-term capital gains are paid at least annually. Dividends and
                capital gains distributions are automatically reinvested in additional shares at net
                asset value unless the shareholder elects to receive cash (see pages 13-14).
- -------------------------------------------------------------------------------------------------------
 
DISTRIBUTOR     Dean Witter Distributors Inc. (the "Distributor"). For its services as Distributor,
AND DISTRIBU-   which include payment of sales commissions to account executives and various other
TION FEE        promotional and sales related expenses, the Distributor receives from the Fund a
                distribution fee accrued daily and payable monthly at the rate of 1% per annum of the
                lesser of (i) the Fund's average daily aggregate net sales or (ii) the Fund's average
                daily net assets. This fee compensates the Distributor for services provided in
                distributing shares of the Fund and for sales related expenses. The Distributor also
                receives the proceeds of any contingent deferred sales charges (see pages 12-13).
- -------------------------------------------------------------------------------------------------------
 
REDEMPTION-     At net asset value; redeemable involuntarily if total value of the account is less than
CONTINGENT      $100 or, if the account was opened through EasyInvest, if after twelve months the
DEFERRED        shareholder has invested less than $1,000 in the account. Although no commission or
SALES CHARGE    sales load is imposed upon the purchase of shares, a contingent deferred sales charge
                (scaled down from 5% to 1%) is imposed on any redemption of shares if after such
                redemption the aggregate current value of an account with the Fund falls below the
                aggregate amount of the investor's purchase payments made during the six years preceding
                the redemption. However, there is no charge imposed on redemption of shares purchased
                through reinvestment of dividends or distributions (see pages 12-13).
- -------------------------------------------------------------------------------------------------------
 
SPECIAL RISK    The net asset value of the Fund's shares will fluctuate with changes in the market value
CONSIDERATIONS  of its portfolio securities. The public utilities industry has certain characteristics
                and risks, and developments within that industry will affect the Fund's portfolio (see
                pages 7-8). The Fund may invest up to 20% of its assets in foreign securities which
                entail additional risks (see page 7). The value of public utility debt securities (and,
                to a lesser extent, equity securities) tends to have an inverse relationship to the
                movement of interest rates.

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
Dean Witter 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 Massachusetts
on December 8, 1987.
 
    Dean Witter InterCapital Inc. ("InterCapital" or the "Investment Manager"),
whose address is Two World Trade Center, New York, New York 10048, is the Fund's
Investment Manager. The Investment Manager, which was incorporated in July,
1992, is a wholly-owned subsidiary of Dean Witter Discover & Co. ("DWDC"), a
balanced financial services organization providing a broad range of nationally
marketed credit and investment products.
 
    InterCapital and its wholly-owned subsidiary, Dean Witter Services Company
Inc., serve in various investment management, advisory, management and
administrative capacities to 102 investment companies, 30 of which are listed on
the New York Stock Exchange, with combined total assets of approximately $89.8
billion at February 28, 1997. The Investment Manager also manages and advises
portfolios of pension plans, other institutions and individuals which aggregated
approximately $3.2 billion at such date.
 
    On February 5, 1997, DWDC and Morgan Stanley Group Inc. announced that they
had entered into an Agreement and Plan of Merger, with the combined company to
be named Morgan Stanley, Dean Witter, Discover & Co. The business of Morgan
Stanley Group Inc. and its affiliated companies is providing a wide range of
financial services for sovereign governments, corporations, institutions and
individuals throughout the world. DWDC is the direct parent of InterCapital and
Dean Witter Distributors Inc., the Fund's distributor. It is currently
anticipated that the transaction will close in mid-1997. Thereafter,
InterCapital and Dean Witter Distributors Inc. will be direct subsidiaries of
Morgan Stanley, Dean Witter, Discover & Co.
 
    The Fund has retained the Investment Manager to provide administrative
services, manage its business affairs and manage the investment of the Fund's
assets. InterCapital has retained Dean Witter Services Company Inc. to perform
the aforementioned administrative services for the Fund.
 
    The Fund's Trustees review the various services provided by or under the
direction of the Investment Manager to ensure that the Fund's general investment
policies and programs are being properly carried out and that administrative
services are being provided to the Fund in a satisfactory manner.
 
    As full compensation for the services and facilities furnished to the Fund
and for expenses of the Fund assumed by the Investment Manager, the Fund pays
the Investment Manager monthly compensation calculated daily by applying the
following annual rates to the net assets of the Fund as of the close of each
business day: 0.65% of the portion of the daily net assets not exceeding $500
million, scaled down at various asset levels to 0.425% of the portion of daily
net assets exceeding $5 billion. For the fiscal year ended December 31, 1996,
the Fund accrued total compensation to the Investment Manager amounting to 0.53%
of the Fund's average daily net assets and the Fund's total expenses amounted to
1.64% of the Fund's average daily net assets.
 
INVESTMENT OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------
 
The investment objective of the Fund is to provide current income and long-term
growth of income and capital. This objective is fundamental and may not be
changed without shareholder approval. There can be no assurance that the
investment objective will be achieved. The Fund seeks to achieve its investment
objective by investing primarily in equity and fixed-income securities of
companies engaged in the public utilities industry. The term "public utilities
industry" consists of companies engaged in the manufacture, production,
generation, transmission, sale and distribution of gas and electric energy, as
well as companies engaged in the communications field, including telephone,
telegraph, satellite, microwave and other companies providing communication
facilities for the public, but excluding public broadcasting companies.
 
    The Fund invests in both equity securities (common stocks and securities
convertible into common stock) and fixed income securities (bonds and preferred
stock) in the public utilities industry. The Fund does not have any set policies
to concentrate within any particular segment of the utilities industry.
 
    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 Trustees. The Fund may also purchase equity and
fixed-income securities issued by foreign issuers.
 
    Investments in fixed-income securities rated either BBB by S&P or Baa by
Moody's (the lowest credit ratings designated "investment grade") may have
speculative characteristics and, therefore, changes in economic conditions or
other circumstances are more likely to weaken their capacity to make principal
and interest payments than would be the case with investments in securities with
higher credit ratings. If a fixed-income security held by the Fund is rated BBB
or Baa and is subsequently downgraded
 
                                                                               5
<PAGE>
by a rating agency, the Fund will retain such security in its portfolio until
the Investment Manager determines 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 total assets, the
Investment Manager will sell immediately securities sufficient to reduce the
total to below 5%.
 
    While the Fund will invest primarily in the securities of public utility
companies, under ordinary circumstances it may invest up to 35% of its total
assets in U.S. Government securities (securities issued or guaranteed as to
principal and interest by the United States or its agencies and
instrumentalities), money market instruments and repurchase agreements, as
described below. U.S. Government securities in which the Fund may invest include
zero coupon securities.
 
    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.
 
RISK CONSIDERATIONS
 
REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements, which may
be viewed as a type of secured lending by the Fund, and which typically involve
the acquisition by the Fund of debt securities from a selling financial
institution such as a bank, savings and loan association or broker-dealer. The
agreement provides that the Fund will sell back to the institution, and that the
institution will repurchase the underlying security at a specified price and at
a fixed time in the future, usually not more than seven days from the date of
purchase. While repurchase agreements involve certain risks not associated with
direct investments in debt securities, the Fund follows procedures designed to
minimize those risks. These procedures include effecting repurchase transactions
only with large, well-capitalized and well-established financial institutions
whose financial condition will be continually monitored by the Investment
Manager subject to procedures established by the Board of Trustees of the Fund.
 
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 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 10% 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 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.
 
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,
 
6
<PAGE>
delayed delivery or forward commitment basis may increase the volatility of the
Fund's net asset value.
 
WHEN, AS AND IF ISSUED SECURITIES.  The Fund may purchase securities on a "when,
as and if issued" basis under which the issuance of the security depends upon
the occurrence of a subsequent event, such as approval of a merger, corporate
reorganization, leveraged buyout or debt restructuring. If the anticipated event
does not occur and the securities are not issued, the Fund will have lost an
investment opportunity. There is no overall limit on the percentage of the
Fund's assets which may be committed to the purchase of securities on a "when,
as and if issued" basis. An increase in the percentage of the Fund's assets
committed to the purchase of securities on a "when, as and if issued" basis may
increase the volatility of the Fund's net asset value.
 
FOREIGN SECURITIES.  The Fund may invest up to 20% of the value of its total
assets, at the time of purchase, in securities issued by foreign issuers, with a
maximum of 10% of the value of its total assets, at the time of purchase,
invested in such securities that are not American Depository Receipts (see
below). 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
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.
 
    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. Finally, in the event of a
default of any foreign debt obligations, it may be more difficult for the Fund
to obtain or enforce a judgment against the issuers of such securities.
 
    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. Investments in certain issuers may be speculative due
to certain political risks and may be subject to substantial price fluctuations.
 
AMERICAN DEPOSITORY RECEIPTS.  The Fund may invest in securities of foreign
issuers in the form of American Depository Receipts (ADRs), including ADRs
sponsored by persons other than the underlying issuers ("unsponsored ADRs").
ADRs are receipts typically issued by a United States bank or trust company
evidencing ownership of the underlying securities. Generally, ADRs, in
registered form, are designed for use in the United States securities markets.
Generally, issuers of the stock of unsponsored ADRs are not obligated to
distribute material information in the United States and, therefore, there may
not be a correlation between such information and the market value of such ADRs.
 
PUBLIC UTILITIES INDUSTRY
 
The public 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 public 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
 
                                                                               7
<PAGE>
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.
 
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"),
a broker-dealer affiliate of InterCapital, the views of Trustees of the Fund 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 Growth and Income Group, which
manages 22 equity funds and fund portfolios with approximately $24.4 billion in
assets as of January 31, 1997. Edward F. Gaylor, Senior Vice President of
InterCapital and a member of InterCapital's Growth and Income Group, has been
the primary portfolio manager of the Fund since its inception and has been a
portfolio manager at InterCapital for over five years.
 
    Orders for transactions in portfolio securities and commodities are placed
for the Fund with a number of brokers and dealers, including DWR. Pursuant to an
order of the Securities and Exchange Commission, the Fund may effect principal
transactions in certain money market instruments with DWR. In addition, the Fund
may incur brokerage commissions on transactions conducted through DWR.
 
    Except as specifically noted, the Fund's investment policies and practices
discussed above are not fundamental policies of the Fund and, as such, may be
changed without shareholder approval.
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
The investment restrictions listed below are among the restrictions which have
been adopted by the Fund as fundamental policies. A fundamental policy may not
be changed without the vote of the Fund's shareholders.
 
    The Fund may not:
 
        1. Invest more than 5% of the value of its total assets in the
    securities of any one issuer (other than obligations issued or guaranteed by
    the United States Government, its agencies or instrumentalities).
 
        2. Purchase more than 10% of all outstanding voting securities or any
    class of securities of any one issuer.
 
        3. Invest 25% or more of the value of its total assets in securities of
    issuers in any one industry, except that the Fund will concentrate in the
    public utilities industry. This restriction does not apply to obligations
    issued or guaranteed by the United States Government or its agencies or
    instrumentalities.
 
        4. Invest more than 10% of its total assets in "illiquid securities"
    (securities for which market quotations are not readily available) and
    repurchase agreements which have a maturity of longer than seven days.
 
        5. 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.
 
PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
The Fund offers its shares for sale to the public on a continuous basis.
Pursuant to a Distribution Agreement between the Fund and Dean Witter
Distributors Inc. (the "Distributor"), an affiliate of the Investment Manager,
shares of the Fund are distributed by the Distributor and offered by DWR and
other brokers and dealers who have entered into agreements with the Distributor
("Selected Broker-Dealers"). The principal executive office of the Distributor
is located at Two World Trade Center, New York, New York 10048.
 
    The minimum initial purchase is $1,000. Subsequent purchases of $100 or more
may be made by sending a check, payable to Dean Witter Utilities Fund, directly
to Dean Witter Trust Company (the "Transfer Agent") at P.O. Box 1040, Jersey
City, NJ 07303 or by contacting a DWR or other Selected Broker-Dealer account
executive. The minimum initial purchase, in the case of investments through
EasyInvest, an automatic purchase plan (see "Shareholder Services"), is $100,
provided that the schedule of automatic investments will result in investments
totalling at least $1,000 within the first twelve months. In the case of
investments pursuant to Systematic Payroll Deduction Plans (including Individual
Retirement Plans), the Fund, in its discretion, may accept investments without
regard to any minimum amounts which would otherwise be required if the Fund has
reason to believe that additional investments will increase the investment in
all accounts under such Plans to at least $1,000. Certificates for shares
purchased
 
8
<PAGE>
will not be issued unless a request is made by the shareholder in writing to the
Transfer Agent.
 
    Shares of the Fund are sold through the Distributor on a normal three
business day settlement basis; that is, payment is due on the third business day
(settlement date) after the order is placed with the Distributor. Shares of the
Fund purchased through the Distributor are entitled to any dividends declared
beginning on the next business day following settlement date. Since DWR and
other Selected Broker-Dealers forward investors' funds on settlement date, they
will benefit from the temporary use of the funds 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.
 
    While no sales charge is imposed at the time shares are purchased, a
contingent deferred sales charge may be imposed at the time of redemption (see
"Redemptions and Repurchases"). Sales personnel are compensated for selling
shares of the Fund at the time of their sale by the Distributor and/or other
Selected Broker-Dealer. In addition, some sales personnel of the Selected
Broker-Dealer will receive various types of non-cash compensation as special
sales incentives, including trips, educational and/or business seminars and
merchandise. The Fund and the Distributor reserve the right to reject any
purchase orders.
 
PLAN OF DISTRIBUTION
 
The Fund has adopted a Plan of Distribution pursuant to Rule 12b-1 under the Act
(the "Plan"), under which the Fund pays the Distributor a fee, which is accrued
daily and payable monthly, at an annual rate of 1% of the lesser of: (a) 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; or (b) the Fund's average daily net
assets. This fee is treated by the Fund as an expense in the year it is accrued.
A portion of the fee payable pursuant to the Plan, equal to 0.25% of the Fund's
average daily net assets, is characterized as a service fee within the meaning
of NASD guidelines. The service fee is a payment made for personal service
and/or the maintenance of shareholder accounts.
 
    Amounts paid under the Plan are 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, including the payment of commissions for
sales of the Fund's shares 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 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 incurred.
 
    For the fiscal year ended December 31, 1996, the Fund accrued payments under
the Plan amounting to $29,551,784, which amount is equal to 1.00% of the Fund's
average daily net assets for the fiscal year. The payments accrued under the
Plan were calculated pursuant to clause (b) of the compensation formula under
the Plan.
 
    At any given time, the Distributor may incur expenses in distributing shares
of the Fund which may be in excess of 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 the redemption of shares (see "Redemptions and
Repurchases--Contingent Deferred Sales Charge"). For example, if $1 million in
expenses in distributing 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 the excess
distribution expenses, including the carrying charge described above, totalled
$79,638,749 at December 31, 1996, which equalled 2.97% of the Fund's net assets
at such date.
 
    Because there is no requirement under the Plan that the Distributor be
reimbursed for all expenses or any requirement that the Plan be continued from
year to year, such excess amount, if any, does not constitute a liability of the
Fund. Although there is no legal obligation for the Fund to pay expenses
incurred in excess of payments made to the Distributor under the Plan and the
proceeds of contingent deferred sales charges paid by investors upon redemption
of shares, if for any reason the Plan is terminated, the Trustees will consider
at that time the manner in which to treat such expenses. Any cumulative expenses
incurred, but not yet recovered through distribution fees or contingent deferred
sales charges, may or may not be recovered through future distribution fees or
contingent deferred sales charges.
 
DETERMINATION OF NET ASSET VALUE
 
The net asset value per share 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 value of all assets of the Fund, subtracting all its
liabilities, dividing by the number of shares outstanding and adjusting to the
nearest cent. The
 
                                                                               9
<PAGE>
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 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 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 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 Board of 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 securities in the Fund's portfolio 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 Fund (or, if specified by the shareholder, any other open-end investment
company for which InterCapital serves as investment manager (collectively, with
the Fund, the "Dean Witter Funds")), unless the shareholder requests that they
be paid in cash. Shares so acquired are not subject to the imposition of a
contingent deferred sales charge upon their redemption (see "Redemptions and
Repurchases").
 
INVESTMENT OF DISTRIBUTIONS RECEIVED IN CASH.  Any shareholder who receives a
cash payment representing a dividend or capital gains distribution may invest
such dividend or distribution 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 not subject to the imposition of a contingent deferred sales charge upon
their redemption (see "Redemptions and Repurchases").
 
EASYINVESTSM.  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, 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 amount, not less than $25, or in any whole
percentage of the account balance, on an annualized basis. Any applicable
contingent deferred sales charge will be imposed on shares redeemed under the
Withdrawal Plan (See "Redemptions and Repurchases--Contingent Deferred Sales
Charge"). 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 contingent deferred sales charge) to the shareholder will
be the designated monthly or quarterly amount.
 
    Shareholders should contact their DWR or other Selected Broker-Dealer
account executive or the Transfer Agent.
 
EXCHANGE PRIVILEGE
 
The Fund makes available to its shareholders an "Exchange Privilege" allowing
the exchange of shares of the Fund for shares of other Dean Witter Funds sold
with a contingent deferred sales charge ("CDSC funds"), and for shares of Dean
Witter Short-Term U.S. Treasury Trust, Dean Witter Limited Term Municipal Trust,
Dean Witter Short-Term Bond Fund, Dean Witter Balanced Growth Fund, Dean Witter
Balanced Income Fund, Dean Witter Intermediate Term U.S. Treasury Trust and five
Dean Witter Funds which are money market funds (the foregoing eleven non-CDSC
funds are hereinafter referred to as the "Exchange 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.
 
10
<PAGE>
    An exchange to another 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 CDSC funds can be effected on the same basis.
No contingent deferred sales charge ("CDSC") is imposed at the time of any
exchange, although any applicable CDSC will be imposed upon ultimate redemption.
Shares of the Fund acquired in exchange for shares of another CDSC Fund having a
different CDSC schedule than that of this Fund will be subject to the CDSC
schedule of this Fund, even if such shares are subsequently re-exchanged for
shares of the CDSC fund originally purchased. 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 (for
the purpose of determining the rate of the CDSC) is frozen. If those shares are
subsequently reexchanged for 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 CDSC fund are reacquired. Thus, the CDSC is based
upon the time (calculated as described above) the shareholder was invested in a
CDSC fund (see "Redemptions and Repurchases--Contingent Deferred Sales Charge").
However, in the case of shares of the Fund exchanged into an Exchange Fund, 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 the date which are
attributable to those shares. (Exchange Fund 12b-1 distribution fees, if any,
are described in the prospectuses for those funds.)
 
    In addition, shares of the Fund may be acquired in exchange for shares of
Dean Witter Funds sold with a front-end sales charge ("front-end sales charge
funds"), but shares of the Fund, however acquired, may not be exchanged for
shares of front-end sales charge funds. Shares of a CDSC fund acquired in
exchange for shares of a front-end sales charge fund (or in exchange for shares
of other Dean Witter Funds for which shares of a front-end sales charge fund
have been exchanged) are not subject to any CDSC upon their redemption.
 
    Purchases and exchanges should be made for investment purposes only. A
pattern of frequent exchanges may be deemed by the Investment Manager to be
abusive and contrary to the best interests of the Fund's other shareholders and,
at the Investment Manager's discretion, may be limited by the Fund's refusal to
accept additional purchases and/or exchanges from the investor. Although the
Fund does not have any specific definition of what constitutes a pattern of
frequent exchanges, and will consider all relevant factors in determining
whether a particular situation is abusive and contrary to the best interests of
the Fund and its other shareholders, investors should be aware that the Fund and
each of the other Dean Witter Funds may in their discretion limit or otherwise
restrict the number of times this Exchange Privilege may be exercised by any
investor. Any such restriction will be made by the Fund on a prospective basis
only, upon notice to the shareholder not later than ten days following such
shareholder's most recent exchange.
 
    The Exchange Privilege may be terminated or revised at any time by the Fund
and/or any of such Dean Witter Funds for which shares of the Fund have been
exchanged, upon such notice as may be required by applicable regulatory
agencies. Shareholders maintaining margin accounts with DWR or another Selected
Broker-Dealer are referred to their account executive regarding restrictions on
exchange of shares of the Fund pledged in the margin account.
 
    The current prospectus for each fund describes its investment objective(s)
and policies, and shareholders should obtain a copy and examine it carefully
before investing. Exchanges are subject to the minimum investment requirement
and any other conditions imposed by each fund. 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 DWR or other Selected Broker-Dealer account
executive (no Exchange Privilege Authorization Form is required). Other
shareholders (and those shareholders who are clients of DWR or another Selected
Broker-Dealer but who wish to make exchanges directly by writing or telephoning
the Transfer Agent) must complete and forward to the Transfer Agent an Exchange
Privilege Authorization Form, copies of which may be obtained from the Transfer
Agent, to initiate an exchange. If the Authorization Form is used, exchanges may
be made 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
 
                                                                              11

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 case with the Dean Witter
Funds in the past.
 
    Shareholders should contact their DWR or other Selected Broker-Dealer
account executive or the Transfer Agent for further information about the
Exchange Privilege.
 
REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 
REDEMPTION.  Shares of the Fund can be redeemed for cash at any time at the net
asset value per share next determined; however, such redemption proceeds may be
reduced by the amount of any applicable contingent deferred sales charges (see
below). If shares are held in a shareholder's account without a share
certificate, a written request for redemption sent to the Fund's Transfer Agent
at P.O. Box 983, Jersey City, NJ 07303 is required. If certificates are held by
the shareholders, the shares may be redeemed by surrendering the certificates
with a written request for redemption, along with any additional documentation
required by the Transfer Agent.
 
CONTINGENT DEFERRED SALES CHARGE.  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 charge upon redemption.
Shares redeemed sooner than six years after purchase may, however, be subject to
a charge upon redemption. This charge is called a "contingent deferred sales
charge" ("CDSC"), and it 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 table below:

              PAYMENT MADE                     AMOUNT REDEEMED
- -----------------------------------------  -----------------------

First....................................               5.0%
Second...................................               4.0%
Third....................................               3.0%
Fourth...................................               2.0%
Fifth....................................               2.0%
Sixth....................................               1.0%
Seventh and thereafter...................           None
</TABLE>
 
    A CDSC will not be imposed on (i) any amount which represents an increase in
value of shares purchased within the six years preceding the redemption; (ii)
the current net asset value of shares purchased more than six years prior to the
redemption; and (iii) the current net asset value of shares purchased through
reinvestment of dividends or distributions and/or shares acquired in exchange
for shares of 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, no CDSC
will be imposed on redemptions of shares which were purchased by the employee
benefit plans established by DWR and SPS Transaction Services, Inc. (an
affiliate of DWR) for their employees as qualified under Section 401(k) of the
Internal Revenue Code.
 
    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.
 
    (3) all redemptions of shares held for the benefit of a participant in a
corporate or self-employed retirement plan qualified under Section 401(k) of the
Internal Revenue Code which offers investment companies managed by the
Investment Manager or its subsidiary, Dean Witter Services Company Inc., as
seslf-directed investment alternatives and for which Dean Witter Trust Company
or Dean Witter Trust FSB, each of which is an affiliate of the Investment
Manager, serves as Trustee ("Eligible 401(k) Plan"),
 
12
<PAGE>
provided that either;  (A) the plan continues to be an Eligibile 401(k) 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.
 
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
or telegraphic request of the shareholder. The repurchase price is the net asset
value next computed (see "Purchase of Fund Shares") after such repurchase order
is received by DWR or other Selected Broker-Dealers, reduced by any applicable
CDSC.
 
    The CDSC, if any, will be the only fee imposed by the Fund, the Distributor,
DWR or other Selected Broker-Dealers. The offers by DWR and other Selected
Broker-Dealers to repurchase shares may be suspended without notice by them at
any time. In that event, shareholders may redeem their shares through the Fund's
Transfer Agent as set forth above under "Redemption."
 
PAYMENT FOR SHARES REDEEMED OR REPURCHASED.  Payment for shares presented for
repurchase or redemption will be made by check within seven days after receipt
by the Transfer Agent of the certificate and/or written request in good order.
Such payment may be postponed or the right of redemption suspended under unusual
circumstances. If the shares to be redeemed have recently been purchased by
check, payment of the redemption proceeds may be delayed for the minimum time
needed to verify that the check used for investment has been honored (not more
than fifteen days from the time of receipt of the check by the Transfer Agent).
Shareholders maintaining margin accounts with DWR or another Selected
Broker-Dealer are referred to their account executive regarding restrictions on
redemption of shares of the Fund pledged in the margin account.
 
REINSTATEMENT PRIVILEGE.  A shareholder who has had his or her shares redeemed
or repurchased and has not previously exercised this reinstatement privilege
may, within thirty 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 at net asset value next determined after a reinstatement
request, together with the proceeds, is received by the Transfer Agent and
receive a pro-rata credit for any CDSC paid in connection with such redemption
or repurchase.
 
INVOLUNTARY REDEMPTION.  The Fund reserves the right, on sixty days' notice, to
redeem, at their net asset value, the shares of any shareholder (other than
shares held in an Individual Retirement Account or Custodial Account under
Section 403(b)(7) of the Internal Revenue Code) whose shares due to redemptions
by the shareholder have a value of less than $100 as a result of redemptions or
repurchases or such lesser amount as may be fixed by the Trustees or, in the
case of an account opened through EasyInvest, if after twelve months the
shareholder has invested less than $1,000 in the account. However, before the
Fund redeems such shares and sends the proceeds to the shareholder, it will
notify the shareholder that the value of the shares is less than the applicable
amount and allow him or her sixty days to make an additional investment in an
amount which will increase the value of his or her account to at least the
applicable amount before the redemption is processed. No CDSC will be imposed on
any involuntary redemption.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
DIVIDENDS AND DISTRIBUTIONS.  The Fund 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 either to distribute or
to retain all or part of any long-term capital gains in any year for
reinvestment.
 
    All dividends and any capital gains distributions will be paid in additional
Fund shares 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. (See "Shareholder
Services--Automatic Investment of Dividends and Distributions".)
 
TAXES.  Because the Fund intends to distribute all of its net investment income
and 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.
Shareholders who are required to pay taxes on their income will normally have to
pay federal income taxes, and any state income taxes, on the dividends and
distributions they receive from the Fund. Such dividends and distributions, to
the extent that they are derived from net investment income or net short-term
capital gains, are taxable to the shareholder as ordinary income regardless of
whether the shareholder receives such payments in additional shares or in cash.
 
                                                                              13
<PAGE>
    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 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.
 
    Long-term and short-term capital gains may be generated by the sale of
portfolio securities by the Fund. 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.
 
    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.
 
    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 "yield" and/or its "total return" in
advertisements and sales literature. Both the yield and the total return of the
Fund are based on historical earnings and are not intended to indicate future
performance. The yield of the Fund is computed by dividing the Fund's net
investment income over a 30-day period by an average value (using the average
number of shares entitled to receive dividends and the net asset value per share
at the end of the period), all in accordance with applicable regulatory
requirements. Such amount is compounded for six months and then annualized for a
twelve-month period to derive the Fund's yield.
 
    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 the Fund of $1,000 over periods of one and five years, as
well as over the life of the Fund. Average annual total return reflects all
income earned by the Fund, any appreciation or depreciation of the Fund's
assets, all expenses incurred by the Fund and all sales charges which would be
incurred by redeeming shareholders, for the period. 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 over
different periods of time by means of aggregate, average, 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 shares of the Fund.
Such calculations may or may not reflect the deduction of the contingent
deferred 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.,
the S&P 500 Stock Index and the Dow Jones Industrial Average).
 
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.
 
    The Fund is not required to hold Annual Meetings of Shareholders for action
by shareholder vote as may be required by the Act or the Declaration of Trust.
Under ordinary 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
limited 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 notice
of such 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 Fund shareholders of personal
liability is remote.
 
CODE OF ETHICS.  Directors, officers and employees of InterCapital, Dean Witter
Services Company Inc. and the Distributor are subject to a strict Code of Ethics
adopted by those companies. The Code of Ethics is intended to ensure that the
interests of shareholders and other clients are
 
14
<PAGE>
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.
 
SHAREHOLDER INQUIRIES.  All inquiries regarding the Fund should be directed to
