TCW/DW     MID-CAP EQUITY TRUST

           PROSPECTUS
           JANUARY 30, 1998

TCW/DW Mid-Cap Equity Trust (the "Fund") is an open-end, diversified management
investment company, whose investment objective is long-term capital 
appreciation. The Fund seeks to achieve its investment objective by investing
primarily in equity securities issued by medium-sized companies whose market
capitalizations, at the time of acquisition, are in the $300 million to $5
billion range and that, in the opinion of the Fund's Adviser, exhibit superior
earnings growth prospects and attractive stock market valuations. See
"Investment Objective and Policies."

The Fund offers four classes of shares (each, a "Class"), each with a different
combination of sales charges, ongoing fees and other features. The different
distribution arrangements permit an investor to choose the method of purchasing
shares that the investor believes is most beneficial given the amount of the
purchase, the length of time the investor expects to hold the shares and other
relevant circumstances. See "Purchase of Fund Shares--Alternative Purchase
Arrangements."

investing in the Fund. It should be read and retained for future reference.
Additional information about the Fund is contained in the Statement of

- -------------------------------------------------------------------------------
DISTRIBUTOR AND     Dean Witter Distributors Inc. (the "Distributor"). The Fund 
DISTRIBUTION        has adopted a distribution plan pursuant to Rule 12b-1  
FEE                 under the Investment Company Act (the "12b-1 Plan") with
                    respect to the distribution fees paid by the Class A, Class
                    B and Class C shares of the Fund to the Distributor. The
                    entire 12b-1 fee payable by Class A and a portion of the
                    12b-1 fee payable by each of Class B and Class C equal to
                    0.25% 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 14 and 20).
- -------------------------------------------------------------------------------
ALTERNATIVE         Four classes of shares are offered:
PURCHASE  
ARRANGEMENTS        o Class A shares are offered with a front-end sales charge,
                    starting at 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 14, 16 and 20).

- -------------------------------------------------------------------------------
                    o Class B shares are offered without a front-end sales
                    charge, but will in most cases be subject to a CDSC (scaled
                    down from 5.0% to 1.0%) if redeemed within six years after
                    purchase. The CDSC will be imposed on any redemption of
                    shares if after such redemption the aggregate current value
                    of a Class B account with the Fund falls below the
                    aggregate amount of the investor's purchase payments made
                    during the six years preceding the redemption. 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
                    14, 18 and 20).

                    o Class C shares are offered without a front-end sales
                    charge, but will in most cases be subject to a CDSC of 1.0%
                    if redeemed within one year after purchase. The Fund is
                    authorized to reimburse the Distributor for specific
                    expenses incurred in promoting the distribution of the
                    Fund's Class C shares and servicing shareholder accounts
                    pursuant to the Fund's 12b-1 Plan. Reimbursement may in no
                    event exceed an amount equal to payments at an annual rate
                    of 1.0% of average daily net assets of the Class (see pages
                    14, 19 and 20).

                    o Class D shares are offered only to investors meeting an
                    initial investment minimum of $5 million ($25 million for
                    certain qualified plans) 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 14, 19 and 20).
- -------------------------------------------------------------------------------
DIVIDENDS AND       Income dividends and capital gains, if any, will be 
CAPITAL GAINS       distributed no less than annually. The Fund may, however,  
DISTRIBUTIONS       determine to retain all or part of any net long-term gains
                    in any year for reinvestment. Dividends and capital gains
                    distributions paid on shares of a Class are automatically
                    reinvested in additional shares of the same Class at net
                    asset value unless the shareholder elects to receive cash.
                    Shares acquired by dividend and distribution reinvestment
                    will not be subject to any sales charge or CDSC (see pages
                    21 and 24).
- -------------------------------------------------------------------------------
REDEMPTION          Shares are redeemable by the shareholder at net asset value
                    less any applicable CDSC on Class A, Class B or Class C
                    shares. An account may be involuntarily redeemed if the
                    total value of the account is less than $100 or, if the
                    account was opened through EasyInvest (Service Mark), if
                    after twelve months the shareholder has invested less than
                    $1,000 in the account (see page 23).
- -------------------------------------------------------------------------------
RISK                The net asset value of the Fund's shares will fluctuate 
CONSIDERATIONS      with changes in the market value of the Fund's portfolio
                    securities. The market value of the Fund's portfolio
                    securities will increase or decrease due to a variety of
                    economic, market or political factors which cannot be
                    predicted. The Fund is intended for long-term investors who
                    can accept the risks involved in seeking long-term capital
                    appreciation through the investment in securities of
                    medium-sized companies whose equity capitalizations are in
                    the $300 million to $5 billion range which involve greater
                    risk of volatility in the Fund's net asset value than is
                    associated with the investment in larger, more established
                    companies. The Fund may invest in foreign securities and
                    may purchase securities on a when-issued, delayed delivery
                    or "when, as and if issued" basis, which may involve
                    certain special risks. An investment in shares of the Fund
                    should not be considered a complete investment program and
                    is not appropriate for all investors. Investors should
                    carefully consider their ability to assume these risks and
                    the risks outlined under the heading "Risk Considerations
                    and Investment Practices," (see pages 10-13) before making
                    an investment in the Fund.

 The above is qualified in its entirety by the detailed information appearing
  elsewhere in this Prospectus and in the Statement of Additional Information.

</TABLE>

- ------------
(1)    Reduced for purchases of $25,000 and over (see "Purchase of Fund
       Shares--Initial Sales Charge Alternative--Class A Shares").
(2)    Investments that are not subject to any sales charge at the time of
       purchase are subject to a CDSC of 1.00% that will be imposed on
       redemptions made within one year after purchase, except for certain
       specific circumstances (see "Purchase of Fund Shares--Initial Sales
       Charge Alternative--Class A Shares").
(3)    The CDSC is scaled down to 1.00% during the sixth year, reaching zero
       thereafter.
(4)    Only applicable to redemptions made within one year after purchase (see
       "Purchase of Fund Shares--Level Load Alternative--Class C Shares").
(5)    The 12b-1 fee is accrued daily and payable monthly. The entire 12b-1
       fee payable by Class A and a portion of the 12b-1 fee payable by each
       of Class B and Class C equal to 0.25% 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
       July 28, 1997. Accordingly, "Total Fund Operating Expenses," as shown
       above with respect to those Classes, are estimates based upon the sum of
       12b-1 Fees, Management Fees and estimated "Other Expenses."

THE FUND AND ITS MANAGEMENT
- -------------------------------------------------------------------------------

   TCW/DW Mid-Cap Equity Trust (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 October 17, 1995.

   Dean Witter Services Company Inc. (the "Manager"), whose address is Two
World Trade Center, New York, New York 10048, is the Fund's Manager. The
Manager is a wholly-owned subsidiary of Dean Witter InterCapital Inc.
("InterCapital"). InterCapital is a wholly-owned subsidiary of Morgan Stanley,
Dean Witter, Discover & Co., a preeminent global financial services firm that
maintains leading market portions in each of its three primary
businesses--securities, asset management and credit services.

   The Manager acts as manager to thirteen other TCW/DW Funds. The Manager and
InterCapital serve in various investment management, advisory, management and
administrative capacities to a total of 103 investment companies, thirty of
which are listed on the New York Stock Exchange, with combined assets of
approximately $98.9 billion as of December 31, 1997. InterCapital also manages
and advises portfolios of pension plans, other institutions and individuals
which aggregated approximately $4 billion at such date.

   The Fund has retained the Manager to manage its business affairs, supervise
its overall day-to-day operations (other than providing investment advice) and
provide all administrative services.

   TCW Funds Management, Inc. (the "Adviser"), whose address is 865 South
Figueroa Street, Suite 1800, Los Angeles, California 90017, is the Fund's
investment adviser. The Adviser was organized in 1987 as a wholly-owned
subsidiary of The TCW Group, Inc. ("TCW"), whose subsidiaries, including Trust
Company of the West and TCW Asset Management Company, provide a variety of
trust, investment management and investment advisory services. Robert A. Day,
who is Chairman of the Board of Directors of TCW, may be deemed to be a control
person of the Adviser by virtue of the aggregate ownership by Mr. Day and his
family of more than 25% of the outstanding voting stock of TCW. The Adviser
serves as investment adviser to thirteen other TCW/DW Funds in addition to the
Fund. As of December 31, 1997, the Adviser and its affiliated companies had
approximately $50 billion under management or committed to management,
primarily from institutional investors.

   The Fund has retained the Adviser to invest the Fund's assets.

   The Fund's Trustees review the various services provided by the Manager and
the Adviser 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 Manager, the Fund pays the Manager
monthly compensation calculated daily by applying the annual rate of 0.60% to
the Fund's net assets. As compensation for its investment advisory services,
the Fund pays the Adviser monthly compensation calculated daily by applying an
annual rate of 0.40% to the Fund's net assets. The total fees paid by the Fund
to the Manager and the Adviser are higher than the fees paid by most other
investment companies for similar services. For the fiscal year ended November
30, 1997, the Fund accrued to the Manager and the Adviser total compensation
amounting to an annualized rate of 0.60% and 0.40%, respectively, of the Fund's
average daily net assets. During the period, the Fund's total expenses of Class
B amounted to an annualized rate of 2.29% of the Fund's average daily net
assets of Class B. Shares of Class A, Class C and Class D were first issued on
July 28, 1997. The expenses of the Fund include: the fees of the Manager and
Adviser; the fee pursuant to the Plan of Distribution (see "Purchase of Fund
Shares"); taxes; transfer agent, custodian and auditing fees; certain legal
fees; and printing and other expenses relating to the Fund's operations which
are not expressly assumed by the Manager under its Management Agreement with
the Fund or by the Adviser under its Investment Advisory Agreement with the
Fund.

INVESTMENT OBJECTIVE AND POLICIES
- -------------------------------------------------------------------------------

   The investment objective of the Fund is long-term capital appreciation. This
objective is fundamental and may not be changed without shareholder approval.
There is no assurance that the objective will be achieved.

   The Fund seeks to achieve its investment objective by investing under normal
circumstances at least 65% of its total assets in equity securities issued by
medium-sized companies whose market capitalizations, at the time of
acquisition, are in the $300 million to $5 billion range and that, in the
opinion of the Adviser, exhibit superior earnings growth prospects and
attractive stock market valuations. The Fund may purchase securities with
market capitalizations not within the $300 million to $5 billion range, but
such securities will not apply to the 65% requirement described above. The
equity securities in which the Fund may invest include common stocks and
convertible securities such as investment grade convertible bonds, notes,
debentures, preferred stocks or other securities convertible into common stock.

                                       8
<PAGE>

   The Adviser pursues a "bottom-up" investment philosophy in investing the
Fund's assets. The "bottom-up" investment process is characterized by the
Adviser's proprietary research process which is to be used in the selection of
investments. Quantitative and qualitative criteria also will be used to screen
the more than 1,000 medium-sized companies within the $300 million to $5
billion market capitalization range thereby providing the Adviser with a list
of potential investment securities. This list of securities is then subjected
to fundamental analysis. The Adviser will consider certain criteria which
include, amongst other things, a demonstrated record of consistent earnings
growth or the potential to grow earnings; an ability to earn an attractive
return on equity; the Adviser's expectation that earnings will exceed Wall
Street research analysts' earnings estimates (i.e., potential for earnings
surprises); a price/earnings ratio which is less than the Adviser's internally
estimated three-year earnings growth rate; a large and growing market share; a
strong balance sheet (i.e., low debt to capitalization ratio); a significant
ownership interest by management and a strong management team. Under normal
market conditions, the Fund intends to hold a portfolio generally containing
approximately 40 to 60 issues. Subject to the Fund's investment objective, the
Adviser may modify the foregoing criteria and analysis without notice.

   Up to 25% of the Fund's total assets may be invested in equity securities of
foreign issuers. Such foreign investments may be in the form of direct
investments in securities of foreign issuers or 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. The Fund's investments in unlisted foreign securities are
subject to the Fund's overall policy limiting its investment in illiquid
securities to 15% or less of its net assets.

   Up to 35% of the Fund's total assets may be invested in equity securities
whose market capitalization at the time of acquisition is not within the $300
million to $5 billion range, as well as in investment grade fixed-income
securities consisting of securities issued or guaranteed by the U.S.
Government, its agencies or instrumentalities, corporate debt securities and
money market instruments. With respect to corporate debt securities, the term
"investment grade" means securities which are rated Baa or higher by Moody's
Investors Services, Inc. ("Moody's") or BBB or higher by Standard & Poor's
Corporation ("S&P") or, if not rated, are deemed by the Adviser to be of
comparable quality. See the Appendix to the Statement of Additional Information
for a discussion of ratings of fixed-income securities.

   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 or convertible security held by
the Fund is rated BBB or Baa and is subsequently downgraded by a rating agency,
or otherwise falls below investment grade, the Fund will sell such security as
soon as is practicable without undue market or tax consequences to the Fund.

   The Fund may also invest up to 5% of its assets in convertible securities
and other fixed-income securities rated below investment grade. Securities
below investment grade are the equivalent of high yield, high risk bonds
(commonly known as "junk bonds"). However, the Fund will not invest in
convertible and other fixed-income securities that are rated lower than B by
S&P or Moody's or, if not rated, determined to be of comparable quality by the
Adviser. The Fund will not invest in fixed-income securities that are in
default in payment of principal or interest. A description of fixed-income
securities ratings is contained in the Appendix to the Statement of Additional
Information. A convertible security is a bond, debenture, note, preferred stock
or other security that may be converted into or exchanged for a prescribed
amount of common stock of the same or a different issuer within a particular
period of time at a specified price or formula. Convertible securities rank
senior to common stocks in a corporation's capital structure and, therefore,
entail less risk than the corporation's common stock. The value of a
convertible security is a function of its "investment value" (its value as if
it did not have a conversion privilege), and its "conversion value" (the
security's worth if it were to be exchanged for the underlying security, at
market value, pursuant to its conversion privilege). To the extent that a
convertible security's investment value is greater than its conversion value,
its price will be primarily a reflection of such investment value and its price
will be likely to increase when interest rates fall and decrease when interest
rates rise, as with a fixed-income security (the credit standing of the issuer
and other factors may also have an effect on the convertible security's value).
If the conversion value exceeds the investment value, the price of the
convertible security will rise above its investment value and, in addition, may
sell at some premium over its conversion value. (This premium represents the
price investors are willing to pay for the privilege of purchasing a
fixed-income security with a possibility of capital appreciation due to the
conversion privilege). At such times the price of the convertible security will
tend to fluctuate directly with the price of the underlying equity security.

                                       9
<PAGE>

   Money market instruments in which the Fund may invest are securities issued
or guaranteed by the U.S. Government or its agencies (Treasury Bills, Notes and
Bonds); obligations of banks subject to regulation by the U.S. Government and
having total assets of $1 billion or more; Eurodollar certificates of deposit;
obligations of savings banks and savings and loan associations having total
assets of $1 billion or more; fully insured certificates of deposit; and
commercial paper rated within the two highest grades by Moody's or S&P or, if
not rated, issued by a company having an outstanding debt issue rated AAA by
S&P or Aaa by Moody's.

   There may be periods during which, in the opinion of the Adviser, 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 up to 100% of its total assets may be invested in money market
instruments or cash.

   The Fund will not invest in options and futures contracts.

RISK CONSIDERATIONS AND
INVESTMENT PRACTICES

   Given the investment risks described below, an investment in shares of the
Fund should not be considered a complete investment program and is not
appropriate for all investors. Investors should carefully consider their
ability to assume these risks before making an investment in the Fund.

   The net asset value of the Fund's shares will fluctuate with changes in the
market value of the Fund's portfolio securities. The market value of the Fund's
portfolio securities will increase or decrease due to a variety of economic,
market or political factors which cannot be predicted. Additionally, the net
asset value of the Fund's shares may increase or decrease due to changes in
prevailing interest rates. Generally, a rise in interest rates will result in a
decrease in the value of the Fund's fixed-income securities, while a drop in
interest rates will result in an increase in the value of those securities.

   Mid-Cap Stocks. The Fund is intended for long-term investors who can accept
the risks involved in seeking long-term capital appreciation through the
investment in securities of medium-sized companies whose market
capitalizations, at the time of acquisition, are in the $300 million to $5
billion range which may involve greater risk of volatility of the Fund's net
asset value than is customarily associated with investing in larger, more
established companies. Often mid-size companies and the industries in which
they are focused are still evolving and while this may offer better growth
potential than larger, established companies, it also may make them more
sensitive to changing market conditions. Because prices of stocks, including
mid-cap stocks, fluctuate from day to day, the value of an investment in the
Fund will vary based upon the Fund's investment performance.

   Convertible Securities. The Fund may acquire, through purchase or a
distribution by the issuer of a security held in its portfolio, a fixed-income
security which is convertible into common stock of the issuer. Convertible
securities rank senior to common stocks in a corporation's capital structure
and, therefore, entail less risk than the corporation's common stock. The value
of a convertible security is a function of its "investment value" (its value as
if it did not have a conversion privilege), and its "conversion value" (the
security's worth if it were to be exchanged for the underlying security, at
market value, pursuant to its conversion privilege).

   To the extent that a convertible security's investment value is greater than
its conversion value, its price will be primarily a reflection of such
investment value and its price will be likely to increase when interest rates
fall and decrease when interest rates rise, as with a fixed-income security
(the credit standing of the issuer and other factors may also have an effect on
the convertible security's value). If the conversion value exceeds the
investment value, the price of the convertible security will rise above its
investment value and, in addition, may sell at some premium over its conversion
value. (This premium represents the price investors are willing to pay for the
privilege of purchasing a fixed-income security with a possibility of capital
appreciation due to the conversion privilege.) At such times the price of the
convertible security will tend to fluctuate directly with the price of the
underlying equity security. In addition, see "High Yield, High Risk Securities"
below for a discussion of the risks of investing in convertible and other
fixed-income securities below investment grade.

   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 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.

   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

                                       10
<PAGE>

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.

   Repurchase Agreements. The Fund may enter into repurchase agreements, which
may be viewed as a type of secured lending by the Fund, and which typically
involve the acquisition by the Fund of debt securities from a selling financial
institution such as a bank, savings and loan association or broker-dealer. The
agreement provides that the Fund will sell back to the institution, and that
the institution will repurchase, the underlying security at a specified price
and at a fixed time in the future, usually not more than seven days from the
date of purchase. While repurchase agreements involve certain risks not
associated with direct investments in debt securities, including the risks of
default or bankruptcy of the selling financial institution, the Fund follows
procedures designed to minimize those risks. These procedures include effecting
repurchase transactions only with large, well-capitalized and well-established
financial institutions and maintaining adequate collateralization. See the
Statement of Additional Information for a further discussion of such
investments.

   Private Placements. The Fund may invest up to 15% 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 Adviser, pursuant to
procedures adopted by the Trustees of the Fund, will make a determination as to
the liquidity of each such restricted security purchased by the Fund. If such
Rule 144A 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.

   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. An
increase in the percentage of the Fund's assets committed to the purchase of
securities on a when-issued, delayed delivery or forward commitment basis may
increase the volatility of the Fund's net asset value. See the Statement of
Additional Information for a further discussion of such investments.

   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. 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. See the
Statement of Additional Information for a further discussion of such
investments.

                                       11
<PAGE>

   Zero Coupon Securities. A portion of the fixed-income securities purchased
by the Fund may be zero coupon securities. Such securities are purchased at a
discount from their face amount, giving the purchaser the right to receive
their full value at maturity. The interest earned on such securities is,
implicitly, automatically compounded and paid out at maturity. While such
compounding at a constant rate eliminates the risk of receiving lower yields
upon reinvestment of interest if prevailing interest rates decline, the owner
of a zero coupon security will be unable to participate in higher yields upon
reinvestment of interest received on interest-paying securities if prevailing
interest rates rise.

   A zero coupon security pays no interest to its holder during its life.
Therefore, to the extent the Fund invests in zero coupon securities, it will
not receive current cash available for distribution to shareholders. In
addition, zero coupon securities are subject to substantially greater price
fluctuations during periods of changing prevailing interest rates than are
comparable securities which pay interest on a current basis. Current federal
tax law requires that a holder (such as the Fund) of a zero coupon security
accrue a portion of the discount at which the security was purchased as income
each year even though the Fund receives no interest payments in cash on the
security during the year.

   Investment in Real Estate Investment Trusts. The Fund may invest in real
estate investment trusts, which pool investors' funds for investments primarily
in commercial real estate properties. Investment in real estate investment
trusts may be the most practical available means for the Fund to invest in the
real estate industry (the Fund is prohibited from investing in real estate
directly). As a shareholder in a real estate investment trust, the Fund would
bear its ratable share of the real estate investment trust's expenses,
including its advisory and administration fees. At the same time the Fund would
continue to pay its own investment management fees and other expenses, as a
result of which the Fund and its shareholders in effect will be absorbing
duplicate levels of fees with respect to investments in real estate investment
trusts.

   Lending of Portfolio Securities. Consistent with applicable regulatory
requirements, the Fund may lend its portfolio securities to brokers, dealers
and other financial institutions, provided that such loans are callable at any
time by the Fund (subject to certain notice provisions described in the
Statement of Additional Information), and are at all times secured by cash or
money market instruments, 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. As with any extensions of credit,
there are risks of delay in recovery and in some cases even loss of rights in
the collateral should the borrower of the securities fail financially. However,
loans of portfolio securities will only be made to firms deemed by the Adviser
to be creditworthy and when the income which can be earned from such loans
justifies the attendant risks.

   High Yield, High Risk Securities. Because of the ability of the Fund to
invest in certain high yield, high risk convertible and other fixed-income
securities (commonly known as "junk bonds"), the Adviser must take into account
the special nature of such securities and certain special considerations in
assessing the risks associated with such investments. Although the growth of
the high yield securities market in the 1980s had paralleled a long economic
expansion, since that time many issuers have been affected by adverse economic
and market conditions. It should be recognized that an economic downturn or
increase in interest rates is likely to have a negative effect on the high
yield bond market and on the value of the high yield securities held by the
Fund, as well as on the ability of the securities' issuers to repay principal
and interest on their borrowings.

   The prices of high yield securities have been found to be less sensitive to
changes in prevailing interest rates than higher-rated investments but more
sensitive to adverse economic changes or individual corporate developments.
During an economic downturn or substantial period of rising interest rates,
highly leveraged issuers may experience financial stress which would adversely
affect their ability to service their principal and interest payment
obligations, to meet their projected business goals or to obtain additional
financing. If the issuer of a fixed-income security owned by the Fund defaults,
the Fund may incur additional expenses to seek recovery. In addition, periods
of economic uncertainty and change can be expected to result in an increased
volatility of market prices of high yield securities and a concomitant
volatility in the net asset value of a share of the Fund.

   The secondary market for high yield securities may be less liquid than the
markets for higher quality securities and, as such, may have an adverse effect
on the market prices of certain securities. The limited liquidity of the market
may also adversely affect the ability of the Fund's Trustees to arrive at a
fair value for certain high yield securities at certain times and could make it
difficult for the Fund to sell certain securities. In addition, new laws and
potential new laws may have an adverse effect upon the value of high yield
securities and a concomitant negative impact upon the net asset value of a
share of the Fund.

   Year 2000. The management services provided to the Fund by the Manager, the
investment advisory services provided to the Fund by the Adviser and the
services provided to shareholders by the Distributor and the Transfer Agent
depend on the smooth functioning of their computer systems. Many computer
software systems in use today cannot recognize the year 2000, but revert to
1900 or some other date, due to the manner in which dates were encoded and
calculated. That failure could have a negative

                                       12
<PAGE>

impact on the handling of securities trades, pricing and account services. The
Manager, the Adviser, the Distributor and the Transfer Agent have been actively
working on necessary changes to their own computer systems to prepare for the
year 2000 and expect that their systems will be adapted before that date, but
there can be no assurance that they will be successful, or that interaction
with other non-complying computer systems will not impair their services at
that time.

PORTFOLIO MANAGEMENT

   The Fund's portfolio is actively managed by its Adviser with a view to
achieving the Fund's investment objective. Douglas S. Foreman, Group Managing
Director of the Adviser, is the Fund's primary portfolio manager and
Christopher J. Ainley, Managing Director of the Adviser, assists Mr. Foreman
in managing the Fund's assets. Mr. Foreman and Mr. Ainley have been portfolio
managers with affiliates of The TCW Group, Inc. since 1994, prior to which
they were portfolio managers with Putnam Investments.

   In determining which securities to purchase for the Fund or hold in the
Fund's portfolio, the Adviser will rely on information from various sources,
including research, analysis and appraisals of brokers and dealers, including
Dean Witter Reynolds Inc. ("DWR"), Morgan Stanley & Co. Incorporated and other
affiliated broker-dealers of the Manager, and others regarding economic
developments and interest rate trends, and the Adviser's own analysis of
factors it deems relevant.

   Orders for transactions in portfolio securities and commodities are placed
for the Fund with a number of brokers and dealers, including DWR, Morgan
Stanley & Co. Incorporated and other brokers and dealers that are affiliates of
the Manager or Adviser. The Fund may incur brokerage commissions on
transactions conducted through such affiliates. The Fund intends to buy and
hold securities for capital appreciation. Although the Fund does not intend to
engage in substantial short-term trading as a means of achieving its investment
objective, the Fund may sell portfolio securities without regard to the length
of time that they have been held, in order to take advantage of new investment
opportunities or yield differentials, or because the Fund desires to preserve
gains or limit losses due to changing economic conditions, interest rate
trends, or the financial condition of the issuer. It is not anticipated that
the Fund's portfolio turnover rate will exceed 150% in any one year. The Fund
will incur underwriting discount costs (on underwritten securities) and
brokerage costs commensurate with its portfolio turnover rate, and thus a
higher level (over 100%) of portfolio transactions will increase the Fund's
overall brokerage expenses. Short term gains and losses may result from such
portfolio transactions. See "Dividends, Distributions and Taxes" for a
discussion of the tax implications of the Fund's transactions.

   The expenses of the Fund relating to its portfolio management are likely to
be greater than those incurred by other investment companies investing only in
securities issued by domestic issuers, as custodial costs, brokerage
commissions and other transaction charges related to investing on foreign
markets are generally higher than in the United States.

   Except as specifically noted, all investment policies and practices
discussed above are not fundamental policies of the Fund and thus may be
changed without shareholder approval.

INVESTMENT RESTRICTIONS
- -------------------------------------------------------------------------------

   The investment restrictions listed below are among the restrictions which
have been adopted by the Fund as fundamental policies. Under the Investment
Company Act of 1940, as amended, (the "Act"), a fundamental policy may not be
changed without the vote of a majority of the outstanding voting securities of
the Fund, as defined in the Act. 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 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. As to 75% of its assets, purchase more than 10% of all outstanding
   voting securities or more than 10% of 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. This restriction does not apply to obligations
   issued or guaranteed by the United States Government, its agencies or
   instrumentalities.

       4. 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 does not apply to
   obligations issued or guaranteed by the United States Government, its
   agencies or instrumentalities.

PURCHASE OF FUND SHARES
- -------------------------------------------------------------------------------

GENERAL

   The Fund offers each class of its shares 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 Manager, shares of
the Fund are distributed by the Distributor and offered by DWR and other
dealers (which may include TCW Brokerage Services, an affiliate of the Adviser)
who have entered into selected broker-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 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 ($25 million for certain qualified plans), 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 ($25 million
for certain qualified plans) or more and to certain other limited categories of
investors. For the purpose of meeting the minimum $5 million (or $25 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 and concurrent investments in Class D shares of the Fund and
other TCW/DW Funds which are multiple class funds ("TCW/DW Multi-Class Funds")
will be aggregated. Subsequent purchases of $100 or more may be made by sending
a check, payable to TCW/DW Mid-Cap Equity Trust, directly to Dean Witter Trust
FSB (the "Transfer Agent" or "DWT") 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 (Service Mark), an automatic purchase plan (see "Shareholder
Services"), is $100, provided that the schedule of automatic investments will
result in investments totalling at least $1,000 within the first twelve months.
The minimum initial investment in the case of an "Education IRA" is $500, if
the Distributor has reason to believe that additional investments will increase
the investment in the account to $1,000 within three years. In the case of
investments pursuant to (i) Systematic Payroll Deduction Plans (including
Individual Retirement Plans), (ii) the InterCapital mutual fund asset
allocation program and (iii) fee-based programs approved by the Distributor,
pursuant to which participants pay an asset based fee for services in the
nature of investment advisory or administrative services, the Fund, in its
discretion, may accept investments without regard to any minimum amounts which
would otherwise be required provided, in the case of Systematic Payroll
Deduction Plans, that the Distributor has reason to believe that additional
investments will increase the investment in all accounts under such Plans to at
least $1,000. Certificates for shares purchased will not be issued unless a
request is made by the shareholder in writing to the Transfer Agent.

   Shares of the Fund are sold through the Distributor on a normal three
business day settlement basis; that is, payment is due on the third business
day (settlement date) after the order is placed with the Distributor. Since DWR
and other Selected Broker-Dealers forward investors' funds on settlement date,
they will benefit from the temporary use of the funds if payment is made prior
thereto. As noted above, orders placed directly with the Transfer Agent must be
accompanied by payment. Investors will be entitled to receive income dividends
and capital gains distributions if their order is received by the close of
business on the day prior to the record date for such dividends and
distributions. Sales personnel of a Selected Broker-Dealer are compensated for
selling shares of the Fund at the time of their sale by the Distributor or any
of its affiliates and/or the Selected Broker-Dealer. In addition, some sales
personnel of the Selected Broker-Dealer will receive various types of non-cash
compensation as special sales incentives, including trips, educational and/or
business seminars and merchandise. The Fund and the Distributor reserve the
right to reject any purchase orders.

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 "Repurchases and
Redemptions."

   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 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
dividends or capital gains distributions), less the average daily aggregate net
asset value of the Fund's Class B shares redeemed since the Fund's inception
upon which a CDSC has been imposed or waived, or (b) the average daily net
assets of Class B. The Class B shares' distribution fee will cause that Class
to have higher expenses and pay lower dividends than Class A or Class D shares.

   After approximately ten (10) years, Class B shares will convert
automatically to Class A shares of the Fund, based on the relative net asset
values of the shares of the two Classes on the conversion date. In addition, a
certain portion of Class B shares that have been acquired through the
reinvestment of dividends and distributions will be converted at that time. See
"Contingent Deferred Sales Charge Alternative--Class B Shares."

   Class C Shares. Class C shares are sold at net asset value with no initial
sales charge but are subject to a CDSC of 1.0% on redemptions made within one
year after purchase. This CDSC may be waived for certain redemptions. They are
subject to an annual 12b-1 fee of up to 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 signifi-

                                      15
<PAGE>

cantly 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 (or $25 million)
investment amount for Class D shares, holdings of Class A shares in all TCW/DW
Multi-Class Funds, and holdings of shares of "Exchange Funds" (see "Shareholder
Services--Exchange Privilege") for which Class A shares have been exchanged,
will be included together with the current investment amount.

   Sales personnel may receive different compensation for selling each Class of
shares. Investors should understand that the purpose of a CDSC is the same as
that of the initial sales charge in that the sales charges applicable to each
Class provide for the financing of the distribution of shares of that Class.

   Set forth below is a chart comparing the sales charge, 12b-1 fees and
conversion options applicable to each Class of shares:

   See "Purchase of Fund Shares" and "The Fund and its Management" for a
complete description of the sales charges and service and distribution fees for
each Class of shares and "Determination of Net Asset Value," "Dividends,
Distributions and Taxes" and "Shareholder Services--Exchange Privilege" for
other differences between the Classes of shares.

INITIAL SALES CHARGE ALTERNATIVE--
CLASS A SHARES

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

   The offering price of Class A shares will be the net asset value per share
next determined following receipt of an order (see "Determination of Net Asset
Value" below), plus a sales charge (expressed as a percentage of the offering
price) on a single transaction as shown in the following table:

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

   The above schedule of sales charges is applicable to purchases in a single
transaction by, among others: (a) an individual; (b) an individual, his or her
spouse and their children under the age of 21 purchasing shares for his, her or
their own accounts; (c) a trustee or other fiduciary purchasing shares for a
single trust estate or a single fiduciary account; (d) a pension,
profit-sharing or other employee benefit plan qualified or non-qualified under
Section 401 of the Internal Revenue Code; (e) tax-exempt

                                       16
<PAGE>

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 TCW/DW Multi-Class Funds. The sales charge payable on the purchase of
the Class A shares of the Fund and the Class A shares of the other TCW/DW
Multi-Class 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 TCW/DW Multi-Class Funds previously
purchased at a price including a front-end sales charge (including shares of
the Fund, other TCW/DW Multi-Class Funds or "Exchange Funds" (see "Shareholder
Services--Exchange Privilege") 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 Class A
and Class D shares that, together with the current investment amount, is equal
to at least $5 million ($25 million for certain qualified plans), 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 Class A shares of other TCW/DW Multi-Class 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 other TCW/DW Multi-Class Funds or shares of
"Exchange Funds" (see "Shareholder Services--Exchange Privilege") acquired in
exchange for Class A 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 "DWT" or Dean Witter Trust FSB ("DWTFSB") (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, mandatory redemption upon termination and
such other circumstances as specified in the program's agreements and
restrictions on transferability of Fund shares);

   (3) employer-sponsored 401(k) and other plans qualified under Section 401(a)
of the Internal Revenue Code ("Qualified Retirement Plans") with at least 200
eligible employees and for which DWT serves as Trustee or DWR's Retirement Plan
Services serves as recordkeeper pursuant to a written Recordkeeping Services
Agreement;

   (4) Qualified Retirement Plans for which DWT serves as Trustee or DWR's
Retirement Plan Services serves as recordkeeper pursuant to a written
Recordkeeping Services Agreement 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

                                       17
<PAGE>

   (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 Qualified Retirement
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, 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 purchased on or after July 28,
1997 by Qualified Retirement Plans for which DWT serves as Trustee or DWR's
Retirement Plan Services serves as recordkeeper pursuant to a written
Recordkeeping Services Agreement, 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 forth in the following table:

   CDSC Waivers. A CDSC will not be imposed on: (i) any amount which represents
an increase in value of shares purchased within the six years (or, in the case
of shares held by certain Qualified Retirement 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 Qualified Retirement
Plans, three years) prior to the redemption; and (iii) the current net asset
value of shares purchased through reinvestment of dividends or distributions.
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
Qualified Retirement Plan which offers

                                       18
<PAGE>

investment companies managed by the Manager or its parent, Dean Witter
InterCapital Inc., as self-directed investment alternatives and for which DWT
serves as Trustee or DWR's Retirement Plan Services serves as recordkeeper
pursuant to a written Recordkeeping Services Agreement ("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 Qualified Retirement Plan for which DWT serves as
Trustee or DWR's Retirement Plan Services serves as recordkeeper pursuant to a
written Recordkeeping Services Agreement, 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 TCW/DW 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 TCW/DW Multi-Class Fund, the holding period resumes on
the last day of the month in which Class B shares are reacquired.

   If a shareholder has received share certificates for Class B shares, such
certificates must be delivered to the Transfer Agent at least one week prior to
the date for conversion. Class B shares evidenced by share certificates that
are not received by the Transfer Agent at least one week prior to any
conversion date will be converted into Class A shares on the next scheduled
conversion date after such certificates are received.

   Effectiveness of the conversion feature is subject to the continuing
availability of a ruling of the Internal Revenue Service or an opinion of
counsel that (i) the conversion of shares does not constitute a taxable event
under the Internal Revenue Code, (ii) Class A shares received on conversion
will have a basis equal to the shareholder's basis in the converted Class B
shares immediately prior to the conversion, and (iii) Class A shares received
on conversion will have a holding period that includes the holding period of
the converted Class B shares. The conversion feature may be suspended if the
ruling or opinion is no longer available. In such event, Class B shares would
continue to be subject to Class B 12b-1 fees.

LEVEL LOAD ALTERNATIVE--CLASS C SHARES

   Class C shares are sold at net asset value next determined without an
initial sales charge but are subject to a CDSC of 1.0% on most redemptions made
within one year after purchase (calculated from the last day of the month in
which the shares were purchased). The CDSC will be assessed on an amount equal
to the lesser of the current market value or the cost of the shares being
redeemed. The CDSC will not be imposed in the circumstances set forth above in
the section "Contingent Deferred Sales Charge Alternative--Class B Shares--CDSC
Waivers," except that the references to six years in the first paragraph of
that section shall mean one year in the case of Class C shares. Class C shares
are subject to an annual 12b-1 fee of up to 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 ($25 million for
Qualified Retirement Plans for which DWT serves as Trustee or DWR's Retirement
Plan Services serves as

                                       19
<PAGE>

recordkeeper pursuant to a written Recordkeeping Services Agreement) 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, referred to in (i) and (ii) above, which may include termination
fees, mandatory redemption upon termination and such other circumstances as
specified in the programs' agreements, and restrictions on transferability of
Fund shares); (iii) certain Unit Investment Trusts sponsored by DWR; (iv)
certain other open-end investment companies whose shares are distributed by the
Distributor; and (v) other categories of investors, at the discretion of the
Board, as disclosed in the then current prospectus of the Fund. Investors who
require a $5 million (or $25 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 TCW/DW
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 (or $25 million) minimum investment amount, holdings of Class A shares
in all TCW/DW Multi-Class Funds, and holdings of shares of "Exchange Funds"
(see "Shareholder Services--Exchange Privilege") for which Class A 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
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 November 30, 1997, Class B shares of the Fund
accrued payments under the Plan amounting to $1,802,459, which amount is equal
to the annualized rate of 1.00% of the average daily net assets of Class B for
the fiscal period. These payments accrued under the Plan were calculated
pursuant to clause (b) of the compensation formula under the Plan. All shares
held prior to July 28, 1997 have been designated Class B shares. For the fiscal
period July 28 through November 30, 1997, Class A and Class B shares of the
Fund accrued payments under the Plan amounting to $46 and $178, respectively,
which amounts on an annualized basis are equal to .25% and 1.00% of the average
daily net assets of Class A and Class C, respectively, for such period.

   In the case of Class B shares, at any given time, the expenses in
distributing Class B shares of the Fund may be in excess of the total of (i)
the payments made by the Fund pursuant to the Plan, and (ii) the proceeds of
CDSCs paid by investors upon the redemption of Class B shares. For example, if
$1 million in expenses in distributing Class B shares of the Fund had been
incurred and $750,000 had been received as described in (i) and (ii) above, the
excess expense would amount to $250,000. The Distributor has advised the Fund
that such excess amounts, including the carrying charge described above,
totalled $9,313,194 at November 30, 1997, which was equal to 5.34% of the net
assets of Class B on such date. Because there is no requirement under the Plan
that the Distributor be reimbursed for all distribution expenses or any
requirement

                                       20
<PAGE>

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 payments in any subsequent year, except that expenses representing a
gross sales commission credited to account executives at the time of sale may
be reimbursed in the subsequent calendar year. The Distributor has advised the
Fund that unreimbursed expenses representing a gross sales commission credited
to account executives at the time of sale totalled $469 in the case of Class C
at December 31, 1997, which amount was equal to 53% of the net assets of Class
C on such date, and that there were no such expenses that may be reimbursed in
the subsequent year in the case of Class A on such date. No interest or other
financing charges will be incurred on any Class A or Class C distribution
expenses incurred by the Distributor under the Plan or on any unreimbursed
expenses due to the Distributor pursuant to the Plan.

DETERMINATION OF NET ASSET VALUE

   The net asset value per share is determined once daily at 4:00 p.m., New
York time (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; 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 Adviser 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. For valuation
purposes, quotations of foreign portfolio securities, other assets and
liabilities and forward contracts stated in foreign currency are translated
into U.S. dollar equivalents at the prevailing market rates prior to the close
of the New York Stock Exchange. Dividends receivable are accrued as of the
ex-dividend date or as of the time that the relevant ex-dividend date and
amounts become known.

   Short-term debt 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.

   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
the pricing service believes is the fair valuation of such portfolio
securities.

SHAREHOLDER SERVICES
- -------------------------------------------------------------------------------

   Automatic Investment of Dividends and Distribu tions. 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 TCW/DW 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 "Repurchases and Redemptions").

   Investment of Dividends or Distributions Received in Cash. Any shareholder
who receives a cash payment representing a dividend or capital gains
distribution in shares of the applicable Class 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 30 days after the payment date. Shares so acquired are acquired at
net asset value and are not subject to the

                                       21
<PAGE>

imposition of a front-end sales charge or a CDSC (see "Repurchases and
Redemptions").

   EasyInvest (Service Mark) . Shareholders may subscribe to EasyInvest, an
automatic purchase plan which provides for any amount from $100 to $5,000 to be
transferred automatically from a checking or savings account, or following
redemption of shares of a Dean Witter money market fund, on a semi-monthly,
monthly or quarterly basis, to the Transfer Agent for investment in shares of
the Fund (see "Purchase of Fund Shares" and "Repurchases and
Redemptions--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 information about any of the above
services.

   Tax Sheltered Retirement Plans. Retirement plans are available for use by
corporations, the self-employed, Individual Retirement Accounts and Custodial
Accounts under Section 403(b)(7) of the Internal Revenue Code. Adoption of such
plans should be on advice of legal counsel or tax adviser.

   For further information regarding plan administration, custodial fees and
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 TCW/DW Multi-Class Fund without the imposition of any exchange fee.
Shares may also be exchanged for shares of TCW/DW North American Government
Income Trust and for shares of five money market funds for which InterCapital
serves as investment manager: Dean Witter Liquid Asset Fund Inc., Dean Witter
U.S. Government Money Market Trust, Dean Witter Tax-Free Daily Income Trust,
Dean Witter California Tax-Free Daily Income Trust and Dean Witter New York
Municipal Money Market Trust (the foregoing six funds are hereinafter
collectively referred to as "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.

   An exchange to another TCW/DW Multi-Class 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 TCW/DW Multi-Class 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 TCW/DW Multi-Class
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 TCW/DW Multi-Class
Fund are reacquired. Thus, the CDSC is based upon the time (calculated as
described above) the shareholder was invested in shares of a TCW/DW Multi-Class
Fund (see "Purchase of Fund Shares"). In the case of shares 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 which are
attributable to those shares. (Exchange Fund 12b-1 distribution fees are
described in the prospectuses for those funds.)

   Additional Information Regarding Exchanges. Purchases and exchanges should
be made for investment purposes only. A pattern of frequent exchanges may be
deemed by the Manager to be abusive and contrary to the best interests of the
Fund's other shareholders and, at the 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

                                       22
<PAGE>

shareholders, investors should be aware that the Fund, each of the other TCW/DW
Funds and each of the money market funds may in its discretion limit or
otherwise restrict the number of times this Exchange Privilege may be exercised
by any investor. Any such restriction will be made by the Fund on a prospective
basis only, upon notice to the shareholder not later than ten days following
such shareholder's most recent exchange. Also, the Exchange Privilege may be
terminated or revised at any time by the Fund and/or any of such TCW/DW Funds
or money market funds for which shares of the Fund have been exchanged, upon
such notice as may be required by applicable regulatory agencies. Shareholders
maintaining margin accounts with DWR or another Selected Broker-Dealer are
referred to their account executive regarding restrictions on exchange of
shares of the Fund pledged in the margin account.

   The current prospectus for each fund describes its investment objective(s)
and policies, and shareholders should obtain a copy and examine it carefully
before investing. Exchanges are subject to the minimum investment requirement
of each Class of shares and any other conditions imposed by each fund. In the
case of a shareholder holding a share certificate or certificates, no exchanges
may be made until all applicable share certificates have been received by the
Transfer Agent and deposited in the shareholder's account. An exchange will be
treated for federal income tax purposes the same as a repurchase or redemption
of shares, on which the shareholder may realize a capital gain or loss.
However, the ability to deduct capital losses on an exchange may be limited in
situations where there is an exchange of shares within ninety days after the
shares are purchased. The Exchange Privilege is only available in states where
an exchange may legally be made.

   If DWR or another Selected Broker-Dealer is the current dealer of record and
its account numbers are part of the account information, shareholders may
initiate an exchange of shares of the Fund for shares of any of the 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
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
will 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 in the past with
other funds managed by the Manager.

   Shareholders should contact their DWR or other Selected Broker-Dealer
account executive or the Transfer Agent for further information about the
Exchange Privilege.

REPURCHASES AND REDEMPTIONS
- -------------------------------------------------------------------------------

   Repurchases. DWR and other Selected 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 per share next computed (see "Purchase of Fund Shares")
after such repurchase order is received by DWR or other Selected Broker-Dealer,
reduced by any applicable CDSC.

   The CDSC, if any, will be the only fee imposed by the Fund or the
Distributor. The 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 below under "Redemptions."

   Redemptions. 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

                                       23
<PAGE>

redeemed by surrendering the certificates with a written request for
redemption, along with any additional information required by the Transfer
Agent.

   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
repurchased or redeemed and has not previously exercised this reinstatement
privilege may, within 35 days after the date of the repurchase or redemption,
reinstate any portion or all of the proceeds of such repurchase or redemption
in shares of the Fund in the same Class from which such shares were redeemed or
repurchased, at net asset value next determined after a reinstatement request,
together with the proceeds, is received by the Transfer Agent and receive a pro
rata credit for any CDSC paid in connection with such repurchase or redemption.

   Involuntary Redemption. The Fund reserves the right, on 60 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 or such lesser amount as may
be fixed by the Trustees or, in the case of an account opened through
EasyInvest (Service Mark), if after twelve months the shareholder has invested
less than $1,000 in the account. However, before the Fund redeems such shares
and sends the proceeds to the shareholder, it will notify the shareholder that
the value of the shares is less than the applicable amount and allow the
shareholder 60 days to make an additional investment in an amount which will
increase the value of his or her account to at least the applicable amount
before the redemption is processed. No CDSC will be imposed on any involuntary
redemption.

DIVIDENDS, DISTRIBUTIONS AND TAXES
- -------------------------------------------------------------------------------

   Dividends and Distributions. The Fund declares dividends separately for each
Class of shares and intends to pay dividends and to distribute substantially
all of the Fund's net investment income and 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 capital gains to shareholders and otherwise qualify as a regulated
investment company under Subchapter M of the Internal Revenue Code, it is not
expected that the Fund will be required to pay any federal income tax.
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.
Any dividends declared with a record date 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. Some part of such dividends and
distributions may be eligible for the Federal dividend received deduction
available to the Fund's corporate shareholders. The Fund may be subject to
foreign withholding taxes and thepass through of such taxes may not be
available to 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

                                       24
<PAGE>

gains distributions for tax purposes. Shareholders will also be notified of
their proportionate share of long-term capital gains distributions that are
eligible for a reduced rate of tax under the Taxpayer Relief Act of 1997.

   Shareholders 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 on
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 one, five and ten years or the
life of the Fund, 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 and all
sales charges which would be incurred by shareholders, forthe stated periods.
It also assumes reinvestment of all dividends and distributions paid by the
Fund.

   In addition to the foregoing, the Fund may advertise its total return for
each Class over different periods of time by means of aggregate, average, and
year-by-year or other types of total return figures. Such calculations may or
may not reflect the deduction of any sales charge which, if reflected, would
reduce the performance quoted. The Fund may also advertise the growth of
hypothetical investments of $10,000, $50,000 and $100,000 in each Class of
shares of the Fund. The Fund from time to time may also advertise its
performance relative to certain performance rankings and indexes compiled by
independent organizations (such as mutual fund performance rankings of Lipper
Analytical Services, Inc.).

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 limitation on shareholder personal liability, and
the nature of the Fund's assets and operations, the possibility of the Fund
being unable to meet its obligations is remote and thus, in the opinion of
Massachusetts counsel to the Fund, the risk to Fund shareholders of personal
liability is remote.

   Code of Ethics. The Adviser is subject to a Code of Ethics with respect to
investment transactions in which the Adviser's officers, directors and certain
other persons have a beneficial interest to avoid any actual or potential
conflict or abuse of their fiduciary position. The Code of Ethics, as it
pertains to the TCW/DW Funds, contains several restrictions and procedures
designed to eliminate conflicts of interest including: (a) pre-clearance of
personal investment transactions to ensure that personal transactions by
employees are not being conducted at the same time as the Adviser's clients;
(b) quarterly reporting of personal securities transactions; (c) a prohibition
against personally acquiring securities in an initial public offering, entering
into uncovered short sales and writing uncovered options; (d) a seven day
"blackout period" prior or subsequent to a TCW/DW Fund transaction during which
portfolio managers are prohibited from making certain transactions in
securities which are being purchased or sold by a TCW/DW Fund; (e) a
prohibition, with respect to certain investment personnel, from profiting in
the purchase and sale, or sale and purchase, of the same (or

                                       25
<PAGE>

equivalent) securities within 60 calendar days; and (f) a prohibition against
acquiring any security which is subject to firm wide or, if applicable, a
department restriction of the Adviser. The Code of Ethics provides that
exemptive relief may be given from certain of its requirements, upon
application. The Adviser's Code of Ethics complies with regulatory requirements
and, insofar as it relates to persons associated with registered investment
companies, the 1994 Report of the Advisory Group on Personal Investing of the
Investment Company Institute.

   Shareholder Inquiries. All inquiries regarding the Fund should be directed
to the Fund at the telephone numbers or address set forth on the front cover
of this Prospectus.
