 ------------------- ------------------------------------------------------------------ 
THE FUND             The Fund is organized as a Trust, commonly known as a Massachusetts 
                     business trust, and is an open-end, non-diversified management investment 
                     company investing primarily in common stocks and other equity securities 
                     of lesser-known, smaller capitalization companies. 
- -------------------  ------------------------------------------------------------------ 
SHARES OFFERED       Shares of beneficial interest with $0.01 par value (see page 25). The 
                     Fund offers four Classes of shares, each with a different combination 
                     of sales charges, ongoing fees and other features (see pages 13-21). 
- -------------------  ------------------------------------------------------------------ 
MINIMUM PURCHASE     The minimum initial investment for each Class is $1,000 ($100 if the 
                     account is opened through EasyInvest (Service Mark) ). 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) 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 multiple class funds for which Dean Witter 
                     Services Company Inc. serves as manager and TCW Funds Management, Inc. 
                     serves as investment adviser will be aggregated. The minimum subsequent 
                     investment is $100 (see page 13). 
- -------------------  ------------------------------------------------------------------

OBJECTIVE 
- -------------------  ------------------------------------------------------------------ 
MANAGER              Dean Witter Services Company Inc. (the "Manager"), a wholly-owned 
                     subsidiary of Dean Witter InterCapital Inc. ("InterCapital"), is the 
                     Fund's manager. The Manager serves as Manager to ten other investment 
                     companies which are advised by TCW Funds Management, Inc. (the "TCW/DW 
                     Funds"). The Manager and InterCapital serve in various investment 
                     management, advisory, management and administrative capacities to a 
                     total of 101 investment companies and other portfolios with assets of 
                     approximately $113.6 billion at March 31, 1998. 
- -------------------  ------------------------------------------------------------------ 
ADVISER              TCW Funds Management, Inc. (the "Adviser") is the Fund's investment 
                     adviser. In addition to the Fund, the Adviser serves as investment adviser 
                     to ten other TCW/DW Funds. As of March 31, 1998, the Adviser and its 
                     affiliates had over $50 billion under management or committed to management 
                     in various fiduciary or advisory capacities, primarily from institutional 
                     investors. 
- -------------------  ------------------------------------------------------------------ 
MANAGEMENT           The Manager receives a monthly fee at the annual rate of 0.60% of daily 
AND ADVISORY         net assets. The Adviser receives a monthly fee at an annual rate of 
FEES                 0.40% of daily net assets (see page 8). 
- -------------------  ------------------------------------------------------------------ 
DISTRIBUTOR AND      Dean Witter Distributors Inc. (the "Distributor"). The Fund has adopted 
DISTRIBUTION         a distribution plan pursuant to Rule 12b-1 under the Investment Company 
FEE                  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 13 and 
                     19). 
- -------------------  ------------------------------------------------------------------ 
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 13, 16 and 19).

                     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 13, 17 and 19).

- --------------------------------------------------------------------------------------- 
                     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 13 and 19).

                     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 13 and 19).
- -------------------  ------------------------------------------------------------------ 
DIVIDENDS AND        Dividends from net investment income and distributions from net capital 
CAPITAL GAINS        gains, if any, are paid at least once each year. The Fund may, however, 
DISTRIBUTIONS        determine to retain all or part of any net long-term capital 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 with changes 
CONSIDERATIONS       in the market value of the Fund's portfolio securities. Investing in 
                     lesser known, smaller capitalization companies may involve greater risk 
                     of volatility in the Fund's net asset value than is customarily associated 
                     with larger, more established companies. The Fund is a non-diversified 
                     investment company and, as such, is not subject to the diversification 
                     requirements of the Investment Company Act of 1940, as amended. As a 
                     result, a relatively high percentage of the Fund's assets may be invested 
                     in a limited number of issuers. However, the Fund intends to continue 
                     to qualify as a regulated investment company under the federal income 
                     tax laws and, as such, is subject to the diversification requirements 
                     of the Internal Revenue Code. The Fund may invest in lower rated or 
                     unrated convertible securities, may invest in foreign securities, may 
                     engage in options and futures transactions, and may purchase securities 
                     on a when-issued, delayed delivery or "when, as and if issued" basis, 
                     which may involve certain special risks (see pages 9-13). In addition, 
                     the Fund's portfolio turnover rate may exceed 100%, which may result 
                     in increased brokerage expenses (see page 13). 
</TABLE>

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."

various costs and expenses that an investor in the Fund will bear directly or 
indirectly. For a more complete description of these costs and expenses, see 
"The Fund and its Management," "Purchase of Fund Shares--Plan of 
Distribution" and "Repurchases and Redemptions." 

   Long-term shareholders of Class B and Class C may pay more in sales 
charges, including distribution fees, than the economic equivalent of the 
maximum front-end sales charges permitted by the NASD.

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

   TCW/DW Small Cap Growth Fund (the "Fund") is an open-end, non-diversified 
management investment company. The Fund is a trust of the type commonly known 
as a "Massachusetts business trust" and was organized under the laws of 
Massachusetts on March 11, 1992. 

   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 & Co., a preeminent global financial services firm that maintains 
leading market positions in each of its three primary businesses--securities, 
asset management and credit services. 

   The Manager acts as manager to ten other TCW/DW Funds. The Manager and 
InterCapital act in various investment management, advisory, management and 
administrative capacities to a total of 101 investment companies, 28 of which 
are listed on the New York Stock Exchange, with combined assets of 
approximately $109.5 billion as of March 31, 1998. InterCapital also manages 
and advises portfolios of pension plans, other institutions and individuals 
which aggregated approximately $4.1 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 The TCW 
Group, Inc. The Adviser serves as investment adviser to ten other TCW/DW 
Funds in addition to the Fund. As of March 31, 1998, the Adviser and its 
affiliated companies had over $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 February 28, 1998, the Fund accrued total compensation to the Manager 
and the Adviser amounting to 0.60% and 0.40%, respectively, of the Fund's 
average daily net assets. During that period, the total expenses of Class B 
amounted to 2.25% of the average daily net assets. Shares of Class A, Class C 
and Class D were first issued on July 28, 1997. The expenses of the Fund 
include: the fee of the Manager and the 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 and the Adviser under their respective Agreements with the Fund. 

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

   The investment objective of the Fund is 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 invests primarily in common stocks and other equity securities of 
lesser known, smaller capitalization companies. The Fund seeks to achieve its 
investment objective by investing under normal circumstances at least 65% of 
its total assets in common stocks and securities convertible into common 
stock of companies with market capitalizations at the time of purchase 
(calculated by multiplying the number of outstanding shares of a company by 
the current market price) of less than $1 billion. Generally, no more than 
25% of the Fund's total assets will be invested in securities of companies 
with market capitalizations of less than $100 million, at the time of 
purchase. Investing in lesser-known, smaller capitalization companies may 
involve greater risk of volatility of the Fund's net asset value than is 
customarily associated with larger, more established companies. The Fund may 
invest up to 35% of its net assets in convertible securities. There are no 
minimum rating or quality requirements with respect to convertible securities 
in which the Fund may 

                                8           
<PAGE>
invest. See the Appendix to the Statement of Additional Information for a 
discussion of ratings of fixed-income securities. 

   The Adviser invests the Fund's assets by pursuing its small cap growth 
investment philosophy. That philosophy consists of fundamental 
company-by-company financial analysis used in conjunction with technical and 
quantitative market analysis to screen potential investments and to 
continuously monitor securities in the Fund's portfolio. Under normal 
circumstances it is expected that the Fund's portfolio will generally contain 
securities of more than 100 separate issuers. Dividend income is not a 
consideration in the selection of stocks for purchase by the Fund. 

   While the Fund invests primarily in common stocks and securities 
convertible into common stock of small capitalization companies, under 
ordinary circumstances it may invest up to 35% of its total assets in (i) 
equity securities of companies with a market capitalization of more than $1 
billion at the time of purchase as long as such investments are consistent 
with the Fund's objective of capital appreciation and (ii) money market 
instruments, which are short-term (maturities of up to thirteen months) 
fixed-income securities issued by private and governmental institutions. 
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 
Investors Service, Inc. ("Moody's") or Standard & Poor's Corporation ("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 greater than 35% of its total assets is invested in money 
market instruments or cash. 

   The Fund is classified as a non-diversified investment company under the 
Investment Company Act of 1940, as amended (the "Act"), and as such is not 
limited by the Act in the proportion of its assets that it may invest in the 
obligations of a single issuer. However, the Fund intends to conduct its 
operations so as to qualify as a "regulated investment company" under 
Subchapter M of the Internal Revenue Code. See "Dividends, Distributions and 
Taxes." In order to qualify, among other requirements, the Fund will limit 
its investments so that at the close of each quarter of the taxable year: (i) 
not more than 25% of the market value of the Fund's total assets will be 
invested in the securities of a single issuer, and (ii) with respect to 50% 
of the market value of its total assets not more than 5% will be invested in 
the securities of a single issuer and the Fund will not own more than 10% of 
the outstanding voting securities of a single issuer. To the extent that a 
relatively high percentage of the Fund's assets may be invested in the 
obligations of a limited number of issuers, the Fund's portfolio securities 
may be more susceptible to any single economic, political or regulatory 
occurrence than the portfolio securities of a diversified investment company. 
The limitations described in this paragraph are not fundamental policies and 
may be revised to theextent applicable Federal income tax requirements are 
revised. 

RISK CONSIDERATIONS AND INVESTMENT PRACTICES 

   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. 

   Small Cap Stocks. As stated above, investing in lesser-known, smaller 
capitalization companies may involve greater risk of volatility of the Fund's 
net asset value than is customarily associated with larger, more established 
companies. Often small capitalization companies and the industries in which 
they are focused are still evolving and while this may offer better growth 
potential than larger, more established companies, it also may make them more 
sensitive to changing market conditions. 

   Foreign securities. The Fund may invest up to 25% of the value of its 
total assets in foreign securities (other than securities of Canadian issuers 
registered under the Securities Exchange Act of 1934 or American Depository 
Receipts, on which there is no such limit). The Fund's investment in unlisted 
foreign securities is subject to the Fund's overall policy limiting its 
investment in illiquid securities to 15% or less of its net assets. 

   When purchasing foreign securities the Fund will generally enter into 
foreign currency exchange transactions or forward foreign exchange contracts 
to facilitate settlement. The Fund will utilize forward foreign exchange 
contracts in these instances as an attempt to limit the effect of changes in 
the relationship between the U.S. dollar and the foreign currency during the 
period between the trade date and settlement date for the transaction. 

   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. 

                                9           
<PAGE>
   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 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. 

   Convertible Securities. A convertible security is a bond, debenture, note, 
preferred stock or other security that may be converted into or exchanged for 
a prescribed amount of common stock of the same or a different issuer within 
a particular period of time at a specified price or formula. Convertible 
securities rank senior to common stocks in a corporation's capital structure 
and, therefore, entail less risk than the corporation's common stock. The 
value of a convertible security is a function of its "investment value" (its 
value as if it did not have a conversion privilege), and its "conversion 
value" (the security's worth if it were to be exchanged for the underlying 
security, at market value, pursuant to its conversion privilege). 

   To the extent that a convertible security's investment value is greater 
than its conversion value, its price will be primarily a reflection of such 
investment value and its price will be likely to increase when interest rates 
fall and decrease when interest rates rise, as with a fixed-income security 
(the credit standing of the issuer and other factors may also have an effect 
on the convertible security's value). If the conversion value exceeds the 
investment value, the price of the convertible security will rise above its 
investment value and, in addition, 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. 

   Because of the special nature of the Fund's permitted investments in lower 
rated convertible securities, the Adviser must take account of certain 
special considerations in assessing the risks associated with such 
investments. (Lower rated convertible and fixed-income securities are 
commonly known as "junk bonds.") The prices of lower rated securities have 
been found to be less sensitive to changes in prevailing interest rates than 
higher rated investments, but are likely to be more sensitive to adverse 
economic changes or individual 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 lower rated securities and a corresponding volatility in 
the net asset value of a share of the Fund. 

   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 such 
risks. These procedures include effecting 

                               10           
<PAGE>
repurchase transactions only with large, well-capitalized and 
well-established financial institutions and maintaining adequate 
collateralization. 

   When-Issued and Delayed Delivery Securities and Forward Commitments. From 
time to time, in the ordinary course of business, the Fund may purchase 
securities on a when-issued or delayed delivery basis or may purchase or sell 
securities on a forward commitment basis. When such transactions are 
negotiated, the price is fixed at the time of the commitment, but delivery 
and payment can take place a month or more after the date of the commitment. 
An increase in the percentage of the Fund's assets committed to the purchase 
of securities on a when-issued, delayed delivery or forward commitment basis 
may increase the volatility of the Fund's net asset value. 

   When, As and If Issued Securities. The Fund may purchase securities on a 
"when, as and if issued" basis under which the issuance of the security 
depends upon the occurrence of a subsequent event, such as approval of a 
merger, corporate reorganization, leveraged buyout or debt restructuring. If 
the anticipated event does not occur and the securities are not issued, the 
Fund will have lost an investment opportunity. 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. 

   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. 

   Private Placements. The Fund may invest up to 5% of its total assets in 
securities which are subject to restrictions on resale because they have not 
been registered under the Securities Act of 1933, as amended (the "Securities 
Act"), or which are otherwise not readily marketable. (Securities eligible 
for resale pursuant to Rule 144A under the Securities Act, and determined to 
be liquid pursuant to the procedures discussed in the following paragraph, 
are not subject to the foregoing restriction.) These securities are generally 
referred to as private placements or restricted securities. Limitations on 
the resale of such securities may have an adverse effect on their 
marketability, and may prevent the Fund from disposing of them promptly at 
reasonable prices. The Fund may have to bear the expense of registering such 
securities for resale and the risk of substantial delays in effecting such 
registration. 

   The Securities and Exchange Commission has adopted Rule 144A under the 
Securities Act, which permits the Fund to sell restricted securities to 
qualified institutional buyers without limitation. The Adviser, pursuant to 
procedures adopted by the Trustees of the Fund, will make a determination as 
to the liquidity of each restricted security purchased by the Fund. If a 
restricted security is determined to be "liquid," such security will not be 
included within the category "illiquid securities," which under current 
policy may not exceed 15% of the Fund's net assets. However, investing in 
Rule 144A securities could have the effect of increasing the level of Fund 
illiquidity to the extent the Fund, at a particular period of time, may be 
unable to find qualified institutional buyers interested in purchasing such 
securities. 

OPTIONS AND FUTURES TRANSACTIONS 

   The Fund may purchase and sell (write) call and put options on portfolio 
securities and on the U.S. dollar which are or may in the future be listed on 
securities exchanges or are written in over-the-counter transactions ("OTC 
options"). Listed options are issued or guaranteed by the exchange on which 
they trade or by a clearing corporation such as the Options Clearing 
Corporation. OTC options are purchased from or sold (written) to dealers or 
financial institutions which have entered into direct agreements with the 
Fund. 
<PAGE>
   The Fund may purchase listed and OTC call and put options in amounts 
equalling up to 5% of its net assets. The Fund may purchase put options on 
securities which it holds in its portfolio only to protect itself against a 
decline in the value of the security. The Fund may also purchase 

                               11           
<PAGE>
put options to close out written put positions. The aggregate value of the 
obligations underlying the puts determined as of the date the options are 
sold will not exceed 50% of the Fund's net assets. There are no other limits 
on the Fund's ability to purchase call and put options. The Fund may write 
covered call and put options on portfolio securities and on the U.S. dollar 
without limit. The Fund may also purchase and write options on stock indexes. 
See "Risks of Options on Indexes" in the Statement of Additional Information. 

   The Fund may purchase and sell futures contracts that are currently 
traded, or may in the future be traded, on commodity exchanges on underlying 
portfolio securities, on fixed-income securities ("interest rate" futures) 
and on such indexes of equity or fixed-income securities as may exist or come 
into being ("index" futures). The Fund will purchase or sell interest rate 
futures contracts for the purpose of hedging some or all of the value of its 
portfolio securities (or anticipated portfolio securities) against changes in 
prevailing interest rates. The Fund will purchase or sell index futures 
contracts for the purpose of hedging some or all of its portfolio (or 
anticipated portfolio) securities against changes in their prices. 

   The Fund also may purchase and write call and put options on futures 
contracts which are traded on an exchange and enter into closing transactions 
with respect to such options to terminate an existing position. 

   New futures contracts, options and other financial products and various 
combinations thereof continue to be developed. The Fund may invest in any 
such futures, options or products as may be developed, to the extent 
consistent with its investment objective and applicable regulatory 
requirements. 

   Risks of Options and Futures Transactions. The Fund may close out its 
position as writer of an option, or as a buyer or seller of a futures 
contract, only if a liquid secondary market exists for options or futures 
contracts of that series. There is no assurance that such a market will 
exist, particularly in the case of OTC options, as such options may generally 
only be closed out by entering into a closing purchase transaction with the 
purchasing dealer. Also, exchanges may limit the amount by which the price of 
many futures contracts may move on any day. If the price moves equal the 
daily limit on successive days, then it may prove impossible to liquidate a 
futures position until the daily limit moves have ceased. 

   While the futures contracts and options transactions to be engaged in by 
the Fund for the purpose of hedging the Fund's portfolio securities are not 
speculative in nature, there are risks inherent in the use of such 
instruments. One such risk is that the Adviser could be incorrect in its 
expectations as to the direction or extent of various interest rate or price 
movements or the time span within which the movements take place. For 
example, if the Fund sold futures contracts for the sale of securities in 
anticipation of an increase in interest rates, and then interest rates went 
down instead, causing bond prices to rise, the Fund would lose money on the 
sale. Another risk which will arise in employing futures contracts to protect 
against the price volatility of portfolio securities is that the prices of 
securities, currencies and indexes subject to futures contracts (and thereby 
the futures contract prices) may correlate imperfectly with the behavior of 
the dollar cash prices of the Fund's portfolio securities and their 
denominated currencies. 

   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 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. 

   In addition, it is possible that the markets for securities in which the 
Fund invests may be detrimentally affected by computer failures throughout 
the financial services industry beginning January 1, 2000. Improperly 
functioning trading systems may result in settlement problems and liquidity 
issues. In addition, corporate and governmental data processing errors may 
result in production problems for individual companies and overall economic 
uncertainties. Earnings of individual issuers will be affected by remediation 
costs, which may be substantial and may be reported inconsistently in U.S. 
and foreign financial statements. Accordingly, the Fund's investments may be 
adversely affected. 

PORTFOLIO MANAGEMENT 

   The Fund's portfolio is actively managed by its Adviser with a view to 
achieving the Fund's investment objective. Charles Larsen, Douglas S. Foreman 
and Christopher J. Ainley, Managing Directors of the Adviser, are the primary 
portfolio managers of the Fund. Mr. Larsen, who has been a primary portfolio 
manager of the Fund since September, 1994, has been a portfolio manager of 
affiliates of The TCW Group, Inc. since 1984. Mr. Foreman and Mr. Ainley, who 
have been primary portfolio managers of the Fund since September, 1994 and 
April, 1998, respectively, have been portfolio managers with affiliates of 
The TCW Group, Inc. since May, 1994, prior to which they were portfolio 
managers with Putnam Investments. 

                               12           
<PAGE>
   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 brokers and dealers that are affiliates 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. The Fund may incur brokerage commissions on transactions 
conducted through DWR, Morgan Stanley & Co. Incorporated and other brokers 
and dealers that are affiliates of the Manager. It is not anticipated that 
the portfolio trading will result in the Fund's portfolio turnover rate 
exceeding 150% in any one year. The Fund will incur 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. See "Dividends, Distributions and Taxes" for a discussion of the 
tax implications of the Fund's trading policy. 

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

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

   The investment restrictions listed below are among the restrictions which 
have been adopted by the Fund as fundamental policies. Under the Act, a 
fundamental policy may not be changed without the vote of a majority of the 
outstanding voting securities of the Fund, as defined in the Act. For 
purposes of the following limitations: (i) all percentage limitations apply 
immediately after a purchase or initial investment, and (ii) any subsequent 
change in any applicable percentage resulting from market fluctuations or 
other changes in total or net assets does not require elimination of any 
security from the portfolio. 

   The Fund may not: 

     1. Invest 25% or more of the value of its total assets in securities of 
    issuers in any one industry. This restriction does not apply to 
    obligations issued or guaranteed by the United States Government, its 
    agencies or instrumentalities. 

     2. Invest more than 5% of the value of its total assets in securities of 
    issuers having a record, together with predecessors, of less than three 
    years of continuous operation. This restriction does not apply to 
    obligations issued or guaranteed by the United States Government, its 
    agencies or instrumentalities. 

   In addition, as a non-fundamental policy, the Fund may not, as to 75% of 
its total assets, purchase more than 10% of the voting securities of any 
issuer. 

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

GENERAL 

   The Fund offers each class of its shares for sale to the public on a 
continuous basis. Pursuant to a Distribution Agreement between the Fund and 
Dean Witter Distributors Inc. (the "Distributor"), an affiliate of the 
Manager, shares of the Fund are distributed by the Distributor and offered by 
DWR and others (which may include TCW Brokerage Services, an affiliate of the 
Adviser) which have entered into selected dealer agreements with the 
Distributor ("Selected Broker-Dealers"). The principal executive office of 
the Distributor is located at Two World Trade Center, New York, New York 
10048. 

   The Fund offers four classes of shares (each, a "Class"). Class A shares 
are sold to investors with an initial sales charge that declines to zero for 
larger purchases; however, Class A shares sold without an initial sales 
charge are subject to a contingent deferred sales charge ("CDSC") of 1.0% if 
redeemed within one year of purchase, except for certain specific 
circumstances. Class B shares are sold without an initial sales charge but 
are subject to a CDSC (scaled down from 5.0% to 1.0%) payable upon most 
redemptions within six years after purchase. (Class B shares purchased by 
certain qualified 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 

                               13           
<PAGE>
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 Small Cap Growth Fund, directly to Morgan Stanley Dean Witter Trust 
FSB (the "Transfer Agent" or "MSDW Trust") at P.O. Box 1040, Jersey City, NJ 
07303, or by contacting an account executive of DWR or any 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 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, administrative 
and/or brokerage 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 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 

                               14           
<PAGE>
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 significantly 
lower CDSC upon redemptions, they do not, unlike Class B shares, convert into 
Class A shares after approximately ten years, and, therefore, are subject to 
an ongoing 12b-1 fee of 1.0% (rather than the 0.25% fee applicable to Class A 
shares) for an indefinite period of time. Thus, Class B shares may be more 
attractive than Class C shares to investors with longer term investment 
outlooks. Other investors, however, may elect to purchase Class C shares if, 
for example, they determine that they do not wish to be subject to a 
front-end sales charge and they are uncertain as to the length of time they 
intend to hold their shares. 

   For the purpose of meeting the $5 million (or $25 million) minimum 
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 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 

                               16           
<PAGE>
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 MSDW Trust (an affiliate of the Manager) provides 
discretionary trustee services; 

   (2) persons participating in a fee-based program approved by the 
Distributor, pursuant to which such persons pay an asset based fee for 
services in the nature of investment advisory, administrative and/or 
brokerage services (such investments are subject to all of the terms and 
conditions of such programs, which may include termination fees, mandatory 
redemption upon termination and such other circumstances as specified in the 
programs' agreements, and restrictions on transferability of Fund shares); 

   (3) 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 MSDW Trust 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 MSDW Trust 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 

   (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 MSDW Trust 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 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 investment companies managed by the 
Manager or its parent, Dean Witter InterCapital Inc., as self-directed 
investment alternatives and for which MSDW Trust 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 MSDW Trust serves as Trustee or 
DWR's Retirement Plan Services serves as recordkeeper pursuant 

                               18           
<PAGE>
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 MSDW Trust serves as Trustee or 
DWR's Retirement Plan services serves as 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, administrative and/or brokerage services (subject to all 
of the terms and conditions of such programs, referred to in (i) and (ii) 
above, which may include termination fees, mandatory redemption upon 
termination and such other circumstances as specified in the programs' 
agreements, and restrictions on transferability of Fund shares); (iii) 
certain Unit Investment Trusts sponsored by DWR; (iv) certain other open-end 
investment companies whose shares are distributed by the Distributor; and (v) 
other categories of investors, at the discretion of the Board, as disclosed 
in the then current prospectus of the Fund. Investors who require a $5 
million (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 

                               19           
<PAGE>
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 February 28, 1998, Class B shares of the Fund 
accrued payments under the Plan amounting to $2,989,560, which amount is 
equal to 0.98% of the average daily net assets of Class B for the fiscal 
year. These payments were calculated pursuant to clause (a) of the 
compensation formula under the Plan. All shares held prior to July 28, 1997 
have been designated Class B shares. For the fiscal period July 28 through 
January 31, 1998, Class A and Class C shares of the Fund accrued payments 
under the Plan amounting to $260 and $3,535, respectively, which amounts on 
an annualized basis are equal to 0.23% 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 $13,685,501 at February 28, 1998, which was equal to 4.02% of the 
net assets of Class B on such date. Because there is no requirement under the 
Plan that the Distributor be reimbursed for all distribution expenses or any 
requirement that the Plan be continued from year to year, such excess amount 
does not constitute a liability of the Fund. Although there is no legal 
obligation for the Fund to pay expenses incurred in excess of payments made 
to the Distributor under the Plan, and the proceeds of CDSCs paid by 
investors upon redemption of shares, if for any reason the Plan is terminated 
the Trustees will consider at that time the manner in which to treat such 
expenses. Any cumulative expenses incurred, but not yet recovered through 
distribution fees or CDSCs, may or may not be recovered through future 
distribution fees or CDSCs. 

   In the case of Class A and Class C shares, expenses incurred pursuant to 
the Plan in any calendar year in excess of 0.25% or 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 $4,948 in the case of Class C at December 31, 1997, which amount was 
equal to 0.68% 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 

                               20           
<PAGE>
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 
stock exchange is valued at its latest sale price on that exchange; if there 
were no sales that day, the security is valued at the latest bid price (in 
cases where a security is traded on more than one exchange, the security is 
valued on the exchange designated as the primary market pursuant to 
procedures adopted by the Trustees), and (2) all other portfolio securities 
for which over-the-counter market quotations are readily available are valued 
at the latest bid price. When market quotations are not readily available, 
including circumstances under which it is determined by the 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 
proce dures established by and under the general supervision of the Board of 
Trustees. 

   Short-term debt securities with remaining maturities of sixty days or less 
at the time of purchase are valued at amortized cost, unless the Trustees 
determine such does not reflect the securities' market value, in which case 
these securities will be valued at their fair value as determined by the 
Trustees. 

   Certain 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 and evaluations by its 
staff, including review of broker-dealer market price quotations, in 
determining what it believes is the fair valuation of the portfolio 
securities valued by such pricing service. 

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

   Automatic Investment of Dividends and Distributions. All income dividends 
and capital gains distributions are automatically paid in full and fractional 
shares of the applicable Class of the Fund (or, if specified by the 
shareholder, in shares of any other open-end 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 may invest such dividend or distribution in shares of the 
applicable Class at the net asset value per share next determined after 
receipt by the Transfer Agent, by returning the check or the proceeds to the 
Transfer Agent within thirty days after the payment date. Shares so acquired 
are acquired at net asset value and are not subject to the imposition of a 
front-end sales charge or a CDSC (see "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 Fund's Transfer Agent for investment in 
shares of the Fund. (See "Purchases 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 further information about any of 
the above services. 

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

   For further information regarding plan administration, custodial fees and 
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 

                               21           
<PAGE>
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 of the 
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 isbased 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"). However, 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 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 

                               22           
<PAGE>
exchange instructions communicated over the telephone are genuine. The 
procedures may include requiring various forms of personal identification 
such as name, mailing address, social security or other tax identification 
number and DWR or other Selected Broker-Dealer account number (if any). 
Telephone instructions will also be recorded. If such procedures are not 
employed, the Fund may be liable for any losses due to unauthorized or 
fraudulent transactions. 

   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 account executive or the Transfer Agent 
for further information about the Exchange Privilege. 

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

   Repurchases. DWR and other Selected Broker-Dealers are authorized to 
repurchase, as agent for the Fund, shares represented by a share certificate 
which is delivered to any of their offices. Shares held in a shareholder's 
account without a share certificate may also be repurchased by DWR and other 
Selected Broker-Dealers upon the telephonic or telegraphic request of the 
shareholder. The repurchase price is the net asset value next computed (see 
"Purchase of Fund Shares") after such repurchase order is received by DWR or 
other Selected Broker-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 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. 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 their net asset value next determined after a 
reinstatement request, together with the proceeds, is received by the 
Transfer Agent and receive a pro rata credit for any CDSC paid in connection 
with such 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. 

                               23           
<PAGE>
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 realized 
short-term and long-term capital gains, if any, at least once each year. The 
Fund may, however, determine either to distribute or to retain all or part of 
any 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 continue to 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 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 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. Dividend payments will generally not be eligible for the 
federal dividends received deduction. 

   Distributions of net long-term capital gains, if any, are taxable to 
shareholders as long-term capital gains regardless of how long a shareholder 
has held the Fund's shares and regardless of whether the distribution is 
received in additional shares or in cash. Capital gains distributions are not 
eligible for the corporate dividends received deduction. 

   The Fund may at times make payments from sources other than income or net 
capital gains. Payments from such sources, in effect, represent a return of a 
portion of each shareholder's investment. All, or a portion, of such payments 
will not be taxable to shareholders. 

   After the end of the calendar year, shareholders will be sent full 
information on their dividends and capital gains distributions for tax 
purposes. 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. To avoid being subject to a 31% 
federal backup withholding tax on taxable dividends, capital gains 
distributions and the proceeds of redemptions and repurchases, shareholders' 
taxpayer identification numbers must be furnished and certified as to their 
accuracy. 

   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 periods of one, five 
and ten years, as well as over 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, for the stated periods. It also assumes 
reinvestment of all dividends and distributions paid by the Fund. 

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

ADDITIONAL INFORMATION 
- ----------------------------------------------------------------------------- 

   Voting Rights. All shares of beneficial interest of the Fund are of $0.01 
par value and are equal as to earnings, assets and voting privileges except 
that each Class will have exclusive voting privileges with respect to matters 
relating to distribution expenses borne solely by such Class or any other 
matter in which the interests of one Class differ from the interests of any 
other Class. In addition, Class B shareholders will have the right to vote on 
any proposed material increase in Class A 's expenses, if such proposal is 
submitted separately to Class A shareholders. Also, as discussed herein, 
Class A, Class B and Class C bear the expenses related to the distribution of 
their respective shares. 

   The Fund is not required to hold Annual Meetings of Shareholders and in 
ordinary circumstances the Fund does not intend to hold such meetings. The 
Trustees may call Special Meetings of Shareholders for action by shareholder 
vote as may be required by the Act or the Declaration of Trust. Under certain 
circumstances the Trustees may be removed by action of the Trustees or by the 
shareholders. 

   Under Massachusetts law, shareholders of a business trust may, under 
certain circumstances, be held personally liable as partners for obligations 
of the Fund. However, the Declaration of Trust contains an express disclaimer 
of shareholder liability for acts or obligations of the Fund, requires that 
Fund obligations include such disclaimer, and provides for indemnification 
and reimbursement of expenses out of the Fund's property for any shareholder 
held personally liable for the obligations of the Fund. Thus, the risk of a 
shareholder incurring financial loss on account of shareholder liability is 
limited to circumstances in which the Fund itself would be unable to meet its 
obligations. Given the above limitations on shareholder personal liability, 
and the nature of the Fund's assets and operations, the possibility of the 
Fund being unable to meet its obligations is remote and 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 "black out period" prior or subsequent to
