PROSPECTUS SUMMARY 
- ----------------------------------------------------------------------- 
<TABLE>
<CAPTION>
<S>            <C>
 THE FUND       The Fund is organized as a Trust, commonly known as a Massachusetts 
                business trust, and is an open-end diversified management investment 
                company investing primarily in securities of smaller and medium-sized 
                companies that have the potential to grow much more rapidly than the 
                economy (see page 6). 
- --------------- ----------------------------------------------------------------------- 
SHARES OFFERED  Shares of beneficial interest with $0.01 par value (see page 22). The 
                Fund offers four Classes of shares, each with a different combination 
                of sales charges, ongoing fees and other features (see pages 10-17). 
- --------------- ----------------------------------------------------------------------- 
MINIMUM         The minimum initial investment for each Class is $1,000 ($100 if the 
PURCHASE        account is opened through EasyInvest (Service Mark) ). Class D shares 
                are only available to persons investing $5 million or more and to 
                certain other limited categories of investors. For the purpose of 
                meeting the minimum $5 million 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 shares of 
                funds for which Dean Witter InterCapital Inc. serves as investment 
                manager ("Dean Witter Funds") that are sold with a front-end sales 
                charge, and concurrent investments in Class D shares of the Fund and 
                other Dean Witter Funds that are multiple class funds, will be 
                aggregated. 
- --------------- ----------------------------------------------------------------------- 
INVESTMENT      The investment objective of the Fund is long-term capital growth. 
OBJECTIVE 
- --------------- ----------------------------------------------------------------------- 
INVESTMENT      The Fund invests primarily in common stock of companies believed to 
POLICIES        have potential for significant growth. However, it may also invest in 
                convertible securities, preferred stock, bonds and warrants of such 
                companies and may engage in certain portfolio techniques, including 
                leveraging (see page 6). 
- --------------- ----------------------------------------------------------------------- 
INVESTMENT      Dean Witter InterCapital Inc. ("InterCapital"), the Investment Manager 
MANAGER         of the Fund, and its wholly-owned subsidiary, Dean Witter Services 
                Company Inc., serve in various investment management, advisory, 
                management and administrative capacities to 100 investment companies 
                and other portfolios with net assets of approximately $96.6 billion at 
                June 30, 1997 (see page 6). 
- --------------- ----------------------------------------------------------------------- 
MANAGEMENT      The Investment Manager receives a monthly fee at the annual rate of 
FEE             0.50% of the Fund's daily net assets on assets not exceeding $500 
                million and 0.475% of the Fund's daily net assets on assets exceeding 
                $500 million (see page 6). 
- --------------- ----------------------------------------------------------------------- 
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 
                10 and 16). 
- --------------- ----------------------------------------------------------------------- 
ALTERNATIVE     Four classes of shares are offered: 
PURCHASE        o Class A shares are offered with a front-end sales charge, starting at 
ARRANGEMENTS    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 10, 12 and 16). 
- --------------- ----------------------------------------------------------------------- 
                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 10, 14 and 
                16).

- --------------- ----------------------------------------------------------------------- 
                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 10 and 16). 

                o Class D shares are offered only to investors meeting an initial 
                investment minimum of $5 million and to certain other limited 
                categories of investors. Class D shares are offered without a front-end 
                sales charge or CDSC and are not subject to any 12b-1 fee (see pages 10 
                and 16). 
- --------------- ----------------------------------------------------------------------- 
DIVIDENDS AND   Dividends from net investment income and distributions from net capital 
CAPITAL GAINS   gains, if any, are paid at least once per year. Dividends and capital 
DISTRIBUTIONS   gains distributions are automatically reinvested in additional shares 
                of the Fund unless the shareholder elects to receive cash. The Fund 
                may, however, 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 18 and 21). 
- --------------- ----------------------------------------------------------------------- 
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 20). 
- --------------- ----------------------------------------------------------------------- 
RISKS           The net asset value of the Fund's shares will fluctuate with changes in 
                the market value of its portfolio securities. The Fund is intended for 
                long-term investors who can accept the risks involved in seeking 
                long-term growth of capital through investment primarily in the 
                securities of small and medium-sized growth companies. It should be 
                recognized that investing in such companies involves greater risk than 
                is customarily associated with more established companies. In addition, 
                investors should consider the risks which may be involved in certain of 
                the investment policies and techniques which the Fund may employ in its 
                operations, including leveraging and investments in foreign securities 
                (see pages 6-9).

- ------------ 
(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 the date of this Prospectus. Accordingly, "Total Fund Operating 
       Expenses," as shown above with respect to those Classes, are based upon 
       the sum of 12b-1 Fees, Management Fees and estimated "Other Expenses."

THE ABOVE EXAMPLES SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR 
FUTURE EXPENSES OR PERFORMANCE. ACTUAL EXPENSES OF EACH CLASS MAY BE GREATER 
OR LESS THAN THOSE SHOWN. 

The purpose of this table is to assist the investor in understanding the 
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 "Redemptions and Repurchases." 

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 
- ----------------------------------------------------------------------------- 

   Dean Witter Developing Growth Securities Trust (the "Fund") is an open-end 
diversified management investment company. The Fund is a trust of the type 
commonly known as a "Massachusetts business trust" and was organized under 
the laws of Massachusetts on December 28, 1982. 

   Dean Witter InterCapital Inc. ("InterCapital" or the "Investment 
Manager"), whose address is Two World Trade Center, New York, New York 10048, 
is the Fund's Investment Manager. The Investment Manager, which was 
incorporated in July, 1992, is a wholly-owned subsidiary of Morgan Stanley, 
Dean Witter, Discover & Co., a preeminent global financial services firm that 
maintains leading market positions in each of its three primary 
businesses--securities, asset management and credit services. 

   InterCapital and its wholly-owned subsidiary, Dean Witter Services Company 
Inc., serve in various investment management, advisory, management and 
administrative capacities to 100 investment companies, thirty of which are 
listed on the New York Stock Exchange, with combined total assets of 
approximately $93.1 billion as of June 30, 1997. The Investment Manager also 
manages portfolios of pension plans, other institutions and individuals which 
aggregated approximately $3.5 billion at such date. 

   The Fund has retained the Investment Manager to provide administrative 
services, manage its business affairs and manage the investment of the Fund's 
assets including the placing of orders for the purchase and sale of portfolio 
securities. InterCapital has retained Dean Witter Services Company Inc. to 
perform the aforementioned administrative services for the Fund. 

   The Fund's Board of Trustees reviews the various services provided by or 
under the direction of the Investment Manager to ensure that the Fund's 
general investment policies and programs are being properly carried out and 
that administrative services are being provided to the Fund in a satisfactory 
manner. 

   As full compensation for the services and facilities furnished to the Fund 
and for expenses of the Fund assumed by the Investment Manager, the Fund pays 
the Investment Manager monthly compensation calculated daily by applying the 
annual rate of 0.50% to the Fund's net assets not exceeding $500 million and 
0.475% to the Fund's net assets exceeding $500 million. For the fiscal year 
ended September 30, 1996, the Fund accrued total compensation to the 
Investment Manager amounting to 0.49% of the Fund's average daily net assets 
and the Fund's total expenses amounted to 1.69% of the Fund's average daily 
net assets. 

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

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

   The Fund seeks to achieve capital growth which significantly exceeds the 
historical total return of common stocks as measured by the Standard & Poor's 
500 index. The primary emphasis is on the securities of smaller and 
medium-sized companies that, in the opinion of the Investment Manager, have 
the potential to grow much more rapidly than the economy; at times, 
investments may also be made in the securities of larger, established 
companies which also have such growth potential. The Fund will normally 
invest at least 65% of its total assets in the securities of such companies. 
In addition to common stock, this portion of the portfolio may also include 
convertible securities, preferred stocks and warrants. 

   The Investment Manager attempts to identify companies whose earnings 
growth will be significantly higher than the average. Dividend income is not 
generally a consideration in the selection of stocks for purchase. 

   The Investment Manager focuses its stock selection for the Fund upon a 
diversified group of emerging growth companies which have moved beyond the 
difficult and extremely risky "start-up" phase and which at the time of 
selection show positive earnings with the prospects of achieving significant 
further profit gains in at least the next two-to-three years after 
acquisition. New technologies, techniques, products or services, 
cost-reducing measures, changes in management, capitalization or asset 
deployment, changes in government regulations or favorable shifts in other 
external circumstances may all contribute to the anticipated phase of growth. 

   The application of the Fund's investment policies is basically dependent 
upon the judgment of the Investment Manager. The proportions of the Fund's 
assets invested in particular industries will shift from time to time in 
accordance with the judgment of the Investment Manager. 

   The Fund may invest up to 35% of its total assets in corporate debt 
securities which are rated at the time of purchase Baa or better by Moody's 
Investors Service Inc. or BBB or better by Standard & Poor's Corporation or 
which, if not rated, are deemed to be of comparable quality by the Investment 
Manager, and money market instruments. There may be periods during which, in 
the opinion of the Investment Manager, general market conditions warrant 
reduction of some or all of the Fund's 

                                6           
<PAGE>
securities holdings. During such periods, the Fund may adopt a temporary 
"defensive" posture in which greater than 35% of its total assets are 
invested in cash or money market instruments, including obligations issued or 
guaranteed as to principal or interest by the United States Government, its 
agencies or instrumentalities, certificates of deposit, bankers' acceptances 
and other obligations of domestic banks having total assets of $1 billion or 
more, and short-term commercial paper of corporations organized under the 
laws of any state or political subdivision of the United States. 

   The securities in which the Fund invests may or may not be listed on a 
national stock exchange, but if they are not so listed, will generally have 
an established over-the-counter market. 

   The Fund may invest in foreign securities, real estate investment trusts 
and private placements, enter into repurchase agreements, borrow money for 
the purpose of leveraging its investments, purchase securities on a 
when-issued or delayed delivery basis, purchase or sell securities on a 
forward commitment basis, purchase securities on a "when, as and if issued" 
basis, and lend its portfolio securities, as discussed under "Risk 
Considerations" below. 

RISK CONSIDERATIONS 

The net asset value of the Fund's shares will fluctuate with changes in the 
market value of its portfolio securities. The market value of the Fund's 
portfolio securities will increase or decrease due to a variety of economic, 
market or political factors which cannot be predicted. The Fund is intended 
for long-term investors who can accept the risks involved in seeking 
long-term growth of capital through investment primarily in the securities of 
small and medium-sized growth companies. It should be recognized that 
investing in such companies involves greater risk than is customarily 
associated with investing in more established companies. 

FOREIGN SECURITIES. The Fund may invest in securities of foreign companies. 
However, the Fund will not invest more than 10% of the value of its total 
assets, at the time of purchase, 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). Foreign 
securities investments may be affected by changes in currency rates or 
exchange control regulations, changes in governmental administration or 
economic or monetary policy (in the United States and abroad) or changed 
circumstances in dealings between nations. Fluctuations in the relative rates 
of exchange between the currencies of different nations will affect the value 
of the Fund's investments denominated in foreign currency. Changes in foreign 
currency exchange rates relative to the U.S. dollar will affect the U.S. 
dollar value of the Fund's assets denominated in that currency and thereby 
impact upon the Fund's total return on such assets. 

   Foreign currency exchange rates are determined by forces of supply and 
demand on the foreign exchange markets. These forces are themselves affected 
by the international balance of payments and other economic and financial 
conditions, government intervention, speculation and other factors. Moreover, 
foreign currency exchange rates may be affected by the regulatory control of 
the exchanges on which the currencies trade. The Fund will incur costs in 
connection with conversions between various currencies. 

   Investments in foreign securities will also occasion risks relating to 
political and economic developments abroad, including the possibility of 
expropriations or confiscatory taxation, limitations on the use or transfer 
of Fund assets and any effects of foreign social, economic or political 
instability. Foreign companies are not subject to the regulatory requirements 
of U.S. companies and, as such, there may be less publicly available 
information about such companies. Moreover, foreign companies are not subject 
to uniform accounting, auditing and financial reporting standards and 
requirements comparable to those applicable to U.S. companies. Finally, in 
the event of a default of any foreign debt obligations, it may be more 
difficult for the Fund to obtain or enforce a judgment against the issuers of 
such securities. 

   Securities of foreign issuers may be less liquid than comparable 
securities of U.S. issuers and, as such, their price changes may be more 
volatile. Furthermore, foreign exchanges and broker-dealers are generally 
subject to less government and exchange scrutiny and regulation than their 
American counterparts. Brokerage commissions, dealer concessions and other 
transaction costs may be higher in foreign markets than in the U.S. In 
addition, differences in clearance and settlement procedures on foreign 
markets may occasion delays in settlements of the Fund's trades effected in 
such markets. As such, the inability to dispose of portfolio securities due 
to settlement delays could result in losses to the Fund due to subsequent 
declines in value of such securities and the inability of the Fund to make 
intended security purchases due to settlement problems could result in a 
failure of the Fund to make potentially advantageous investments. Investments 
in certain Canadian issuers may be speculative due to certain political risks 
and may be subject to substantial price fluctuations. 

REPURCHASE AGREEMENTS. The Fund may enter into repurchase agreements, which 
may be viewed as a type of secured lending by the Fund, and which typically 
involve the acquisition by the Fund of debt securities from a selling 
financial institution such as a bank, savings and loan association or 
broker-dealer. The agreement provides that the Fund will sell back to the 
institution, and that the institution will repurchase, the underlying 
security at a specified price and at a fixed time in the future, usually not 
more than seven days from the date of purchase. While repurchase agreements 
involve certain risks not associated with direct investments in debt 
securities, the Fund follows procedures designed to 

                                7           
<PAGE>
minimize those risks. These procedures include effecting repurchase 
transactions only with large, well-capitalized and well-established financial 
institutions whose financial condition will be continually monitored by the 
Investment Manager subject to procedures established by the Board of Trustees 
of the Fund. In addition, the value of the collateral underlying the 
repurchase agreement will be at least equal to the repurchase price, 
including any accrued interest earned on the repurchase agreement. In the 
event of a default or bankruptcy by a selling financial institution, the Fund 
will seek to liquidate such collateral. However, the exercising of the Fund's 
right to liquidate such collateral could involve certain costs or delays and, 
to the extent that proceeds from any sale upon a default of the obligation to 
repurchase were less than the repurchase price, the Fund could suffer a loss. 
The Fund may not invest in repurchase agreements that do not mature within 
seven days if any such investment, together with any other illiquid assets 
held by the Fund, amounts to more than 15% of its net assets. 

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 below, are not subject to the 
foregoing restriction.) These securities are generally referred to as private 
placements or restricted securities. The Securities and Exchange Commission 
has adopted Rule 144A under the Securities Act, which permits the Fund to 
sell restricted securities to qualified institutional buyers without 
limitation. The Investment Manager, pursuant to procedures adopted by the 
Trustees of the Fund, will make a determination as to the liquidity of each 
restricted security purchased by the Fund. If a restricted security is 
determined to be "liquid," such security will not be included within the 
category "illiquid securities", which under current policy may not exceed 15% 
of the Fund's net assets. Limitations on the resale of private placements 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. In the case of restricted 
securities determined to be "liquid" pursuant to Rule 144A under the 
Securities Act, the Fund's illiquidity could increase if qualified 
institutional buyers become unavailable. 

CONVERTIBLE SECURITIES. A convertible security is a bond, debenture, note, 
preferred stock or other security that may be converted into or exchanged for 
a prescribed amount of common stock of the same or a different issuer within 
a particular period of time at a specified price or formula. Convertible 
securities rank senior to common stocks in a corporation's capital structure 
and, therefore, entail less risk than the corporation's common stock. The 
value of a convertible security is a function of its "investment value" (its 
value as if it did not have a conversion privilege), and its "conversion 
value" (the security's worth if it were to be exchanged for the underlying 
security, at market value, pursuant to its conversion privilege). To the 
extent that a convertible security's investment value is greater than its 
conversion value, its price will be primarily a reflection of such investment 
value and its price will be likely to increase when interest rates fall and 
decrease when interest rates rise, as with a fixed-income security (the 
credit standing of the issuer and other factors may also have an effect on 
the convertible security's value). If the conversion value exceeds the 
investment value, the price of the convertible security will rise above its 
investment value and, in addition, the convertible security will sell at some 
premium over its conversion value. (This premium represents the price 
investors are willing to pay for the privilege of purchasing a fixed-income 
security with a possibility of capital appreciation due to the conversion 
privilege.) At such times the price of the convertible security will tend to 
fluctuate directly with the price of the underlying equity security. 

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. 

LEVERAGING. The Fund may borrow money, but only from a bank and in an amount 
up to 25% of the value of the Fund's total assets (including the amount 
borrowed) less its liabilities (not including any borrowings but including 
the fair market value at the time of computation of any other senior 
securities then outstanding). When the Fund borrows it will be because it 
seeks to enhance capital appreciation by leveraging its investments through 
purchasing securities with the borrowed funds. The Fund will be required to 
maintain an asset coverage (including the proceeds of borrowings) of at least 
300% of such borrowings in accordance with the provisions of the Investment 
Company Act of 1940 (the "Act"). The investment policy also provides that the 
Fund may not purchase or sell a security on margin. 

   Borrowings for leveraging will be subject to current margin requirements 
of the Federal Reserve Board and where necessary the Fund may use any or all 
of its securities as collateral for such borrowings. Any investment gains 
made with the additional monies in 

                                8           
<PAGE>
excess of interest paid will cause the net asset value of the Fund's shares 
to rise to a greater extent than would otherwise be the case. Conversely, if 
the investment performance of the additional monies fails to cover their cost 
to the Fund, net asset value will decrease to a greater extent than would 
otherwise be the case. This is the speculative factor involved in leverage. 
If, due to market fluctuations or other reasons, the value of the Fund's 
assets (including the proceeds of borrowings) becomes at any time less than 
three times the amount of any outstanding bank debt, the Fund, within three 
business days, will reduce its bank debt to the extent necessary to meet the 
required 300% asset coverage. In doing this, the Fund may have to sell a 
portion of its investments at a time when it may be disadvantageous to do so. 

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS. From 
time to time, in the ordinary course of business, the Fund may purchase 
securities on a when-issued or delayed delivery basis or may purchase or sell 
securities on a forward commitment basis. When such transactions are 
negotiated, the price is fixed at the time of the commitment, but delivery 
and payment can take place a month or more after the date of the commitment. 
There is no overall limit on the percentage of the Fund's assets which may be 
committed to the purchase of securities on a when-issued, delayed delivery or 
forward commitment basis. An increase in the percentage of the Fund's assets 
committed to the purchase of securities on a when-issued, delayed delivery or 
forward commitment basis may increase the volatility of the Fund's net asset 
value. 

WHEN, AS AND IF ISSUED SECURITIES. The Fund may purchase securities on a 
"when, as and if issued" basis under which the issuance of the security 
depends upon the occurrence of a subsequent event, such as approval of a 
merger, corporate reorganization, leveraged buyout or debt restructuring. If 
the anticipated event does not occur and the securities are not issued, the 
Fund will have lost an investment opportunity. There is no overall limit on 
the percentage of the Fund's assets which may be committed to the purchase of 
securities on a "when, as and if issued" basis. An increase in the percentage 
of the Fund's assets committed to the purchase of securities on a "when, as 
and if issued" basis may increase the volatility of the Fund's net asset 
value. 

LENDING OF PORTFOLIO SECURITIES. Consistent with applicable regulatory 
requirements, the Fund may lend its portfolio securities to brokers, dealers 
and other financial institutions, provided that such loans are callable at 
any time by the Fund (subject to certain notice provisions described in the 
Statement of Additional Information), and are at all times secured by cash or 
money market instruments, which are maintained in a segregated account 
pursuant to applicable regulations and that are equal to at least the market 
value, determined daily, of the loaned securities. As with any extensions of 
credit, there are risks of delay in recovery and in some cases even loss of 
rights in the collateral should the borrower of the securities fail 
financially. However, loans of portfolio securities will only be made to 
firms deemed by the Investment Manager to be creditworthy and when the income 
which can be earned from such loans justifies the attendant risks. 

   For additional risk disclosure, please refer to the "Investment Objective 
and Policies" section of the Prospectus and to the "Investment Practices and 
Policies" section of the Statement of Additional Information. 

PORTFOLIO MANAGEMENT 

The Fund's portfolio is actively managed by its Investment Manager with a 
view to achieving the Fund's investment objective. No particular emphasis is 
given to investments in securities for the purpose of earning current income. 
In determining which securities to purchase for the Fund or hold in the 
Fund's portfolio, the Investment Manager will rely on information from 
various sources, including research, analysis and appraisals of brokers and 
dealers, including Dean Witter Reynolds Inc. ("DWR") and other broker-dealer 
affiliates of InterCapital, the views of others regarding economic 
developments and interest rate trends, and the Investment Manager's own 
analysis of factors it deems relevant. The Fund is managed within 
InterCapital's Growth Group, which manages 31 funds and fund portfolios, with 
approximately $13.5 billion in assets at June 30, 1997. Jayne Stevlingson, 
Senior Vice President of InterCapital and a member of InterCapital's Growth 
Group, is the primary portfolio manager of the Fund. Ms. Stevlingson has been 
a portfolio manager of the Fund since September, 1994 and has been the sole 
portfolio manager of the Fund since November, 1995. She has been a portfolio 
manager with InterCapital since October, 1992, prior to which time she was an 
analyst with Bankers Trust New York Corp. 

   Orders for transactions in portfolio securities are placed for the Fund 
with a number of brokers, including DWR and other broker-dealer affiliates of 
InterCapital. Pursuant to an order of the Securities and Exchange Commission, 
the Fund may effect principal transactions in certain money market 
instruments with DWR. In addition, the Fund may incur brokerage commissions 
on transactions conducted through DWR and other brokers and dealers that are 
affiliates of InterCapital. 

   The portfolio trading engaged in by the Fund may result in its portfolio 
turnover rate exceeding 200%, although it is not anticipated that this rate 
will exceed 300%. 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. A more extensive discussion of the Fund's 
portfolio brokerage policies is set forth in the Statement of Additional 
Information.

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

   The investment restrictions listed below have been adopted by the Fund as 
fundamental policies, along with certain other investment restrictions. 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. 

   The Fund may not: 

   1. Invest more than 5% of the value of its total assets in the securities 
of any one issuer (other than obligations issued, or guaranteed, by the 
United States Government, its agencies or instrumentalities). 

   2. Purchase more than 10% of all outstanding voting securities or any 
class of securities of any one issuer. 

   3. Concentrate its investments in any particular industry, but if deemed 
appropriate for attainment of its investment objective, up to 25% of its 
total assets (valued at the time of investment) may be invested in any one 
industry classification used by the Fund for investment purposes. This 
restriction does not apply to obligations issued or guaranteed by the United 
States Government or its agencies or instrumentalities. 

   4. Invest more than 5% of the value of its total assets in securities of 
issuers having a record, together with predecessors, of less than three years 
of continuous operation. This restriction shall not apply to any obligation 
of the United States Government, its agencies or instrumentalities. 

   5. Borrow money, except from banks for investment purposes or as a 
temporary measure for extraordinary or emergency purposes, within the limits 
set forth in the Act (see "Leveraging," above). 

   If a percentage restriction is adhered to at the time of investment, a 
later increase or decrease in percentage resulting from a change in values of 
portfolio securities or amount of total or net assets will not be considered 
a violation of any of the foregoing restrictions. 

   Notwithstanding any other investment policy or restriction, the Fund may 
seek to achieve its investment objective by investing all or substantially 
all of its assets in another investment company having substantially the same 
investment objective and policies as the Fund. 

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

GENERAL 

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

   The Fund offers four classes of shares (each, a "Class"). Class A shares 
are sold to investors with an initial sales charge that declines to zero for 
larger purchases; however, Class A shares sold without an initial sales 
charge are subject to a contingent deferred sales charge ("CDSC") of 1.0% if 
redeemed within one year of purchase, except for certain specific 
circumstances. Class B shares are sold without an initial sales charge but 
are subject to a CDSC (scaled down from 5.0% to 1.0%) payable upon most 
redemptions within six years after purchase. (Class B shares purchased by 
certain qualified employer-sponsored benefit plans are subject to a CDSC 
scaled down from 2.0% to 1.0% if redeemed within three years after purchase.) 
Class C shares are sold without an initial sales charge but are subject to a 
CDSC of 1.0% on most redemptions made within one year after purchase. Class D 
shares are sold without an initial sales charge or CDSC and are available 
only to investors meeting an initial investment minimum of $5 million, and to 
certain other limited categories of investors. At the discretion of the Board 
of Trustees of the Fund, Class A shares may be sold to categories of 
investors in addition to those set forth in this prospectus at net asset 
value without a front-end sales charge, and Class D shares may be sold to 
certain other categories of investors, in each case as may be described in 
the then current prospectus of the Fund. See "Alternative Purchase 
Arrangements--Selecting a Particular Class" for a discussion of factors to 
consider in selecting which Class of shares to purchase. 

   The minimum initial purchase is $1,000 for each Class of shares, although 
Class D shares are only available to persons investing $5 million or more and 
to certain other limited categories of investors. For the purpose of meeting 
the minimum $5 million initial investment for Class D shares, and subject to 
the $1,000 minimum initial investment for each Class of the Fund, an 
investor's existing holdings of Class A shares of the Fund and other Dean 
Witter Funds that are multiple class funds ("Dean Witter Multi-Class Funds") 
and shares of Dean Witter Funds sold with a front-end sales charge ("FSC 
Funds") and concurrent investments in Class D shares of the Fund and other 
Dean Witter Multi-Class Funds will be aggregated. Subsequent purchases of 
$100 or more may be made by sending a check, payable to Dean Witter 
Developing Growth Securities Trust, directly to Dean Witter Trust Company 
(the "Transfer Agent") at P.O. Box 1040, Jersey City, NJ 07303 or by 
contacting an account 

                               10           
<PAGE>
executive of DWR or other Selected Broker-Dealer. When purchasing shares of 
the Fund, investors must specify whether the purchase is for Class A, Class 
B, Class C or Class D shares. If no Class is specified, the Transfer Agent 
will not process the transaction until the proper Class is identified. The 
minimum initial purchase in the case of investments through EasyInvest 
(Service Mark), an automatic purchase plan (see "Shareholder Services"), is 
$100, provided that the schedule of automatic investments will result in 
investments totalling $1,000 within the first twelve months. In the case of 
investments pursuant to Systematic Payroll Deduction Plans (including 
Individual Retirement Plans), the Fund, in its discretion, may accept 
investments without regard to any minimum amounts which would otherwise be 
required, if the Fund has reason to believe that additional investments will 
increase the investment in all accounts under such Plans to at least $1,000. 
Certificates for shares purchased will not be issued unless requested by the 
shareholder in writing to the Transfer Agent. 

   Shares of the Fund are sold through the Distributor on a normal three 
business day settlement basis; that is, payment is due on the third business 
day (settlement date) after the order is placed with the Distributor. Since 
DWR and other Selected Broker-Dealers forward investors' funds on settlement 
date, they will benefit from the temporary use of the funds if payment is 
made prior thereto. As noted above, orders placed directly with the Transfer 
Agent must be accompanied by payment. Investors will be entitled to receive 
income dividends and capital gains distributions if their order is received 
by the close of business on the day prior to the record date for such 
dividends and distributions. While no sales charge is imposed at the time 
shares are purchased, a contingent deferred sales charge may be imposed at 
the time of redemption (see "Redemptions and Repurchases"). Sales personnel 
of a Selected Broker-Dealer are compensated for selling shares of the Fund by 
the Distributor or any of its affiliates and/or the Selected Broker-Dealer. 
In addition, some sales personnel of the Selected Broker-Dealer will receive 
various types of non-cash compensation as special sales incentives, including 
trips, educational and/or business seminars and merchandise. The Fund and the 
Distributor reserve the right to reject any purchase orders. 

ALTERNATIVE PURCHASE ARRANGEMENTS 

The Fund offers several Classes of shares to investors designed to provide 
them with the flexibility of selecting an investment best suited to their 
needs. The general public is offered three Classes of shares: Class A shares, 
Class B shares and Class C shares, which differ principally in terms of sales 
charges and rate of expenses to which they are subject. A fourth Class of 
shares, Class D shares, is offered only to limited categories of investors 
(see "No Load Alternative--Class D Shares" below). 

   Each Class A, Class B, Class C or Class D share of the Fund represents an 
identical interest in the investment portfolio of the Fund except that Class 
A, Class B and Class C shares bear the expenses of the ongoing shareholder 
service fees, Class B and Class C shares bear the expenses of the ongoing 
distribution fees and Class A, Class B and Class C shares which are redeemed 
subject to a CDSC bear the expense of the additional incremental distribution 
costs resulting from the CDSC applicable to shares of those Classes. The 
ongoing distribution fees that are imposed on Class A, Class B and Class C 
shares will be imposed directly against those Classes and not against all 
assets of the Fund and, accordingly, such charges against one Class will not 
affect the net asset value of any other Class or have any impact on investors 
choosing another sales charge option. See "Plan of Distribution" and 
"Redemptions and Repurchases." 

   Set forth below is a summary of the differences between the Classes and 
the factors an investor should consider when selecting a particular Class. 
This summary is qualified in its entirety by detailed discussion of each 
Class that follows this summary. 

CLASS A SHARES. Class A shares are sold at net asset value plus an initial 
sales charge of up to 5.25%. The initial sales charge is reduced for certain 
purchases. Investments of $1 million or more (and investments by certain 
other limited categories of investors) are not subject to any sales charges 
at the time of purchase but are subject to a CDSC of 1.0% on redemptions made 
within one year after purchase, except for certain specific circumstances. 
Class A shares are also subject to a 12b-1 fee of up to 0.25% of the average 
daily net assets of the Class. See "Initial Sales Charge Alternative--Class A 
Shares." 

CLASS B SHARES. Class B shares are offered at net asset value with no initial 
sales charge but are subject to a CDSC (scaled down from 5.0% to 1.0%) if 
redeemed within six years of purchase. (Class B shares purchased by certain 
qualified employer-sponsored benefit plans are subject to a CDSC scaled down 
from 2.0% to 1.0% if redeemed within three years after purchase.) This CDSC 
may be waived for certain redemptions. Class B shares are also subject to an 
annual 12b-1 fee of 1.0% of the lesser of: (a) the average daily aggregate 
gross sales of the Fund's Class B shares since the inception of the Fund (not 
including reinvestments of 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 

                               11           
<PAGE>
two Classes on the conversion date. In addition, a certain portion of Class B 
shares that have been acquired through the reinvestment of dividends and 
distributions will be converted at that time. See "Contingent Deferred Sales 
Charge Alternative--Class B Shares." 

CLASS C SHARES. Class C shares are sold at net asset value with no initial 
sales charge but are subject to a CDSC of 1.0% on redemptions made within one 
year after purchase. This CDSC may be waived for certain redemptions. They 
are subject to an annual 12b-1 fee of up to 1.0% of the average daily net 
assets of the Class C shares. The Class C shares' distribution fee may cause 
that Class to have higher expenses and pay lower dividends than Class A or 
Class D shares. See "Level Load Alternative--Class C Shares." 

CLASS D SHARES. Class D shares are available only to limited categories of 
investors (see "No Load Alternative--Class D Shares" below). Class D shares 
are sold at net asset value with no initial sales charge or CDSC. They are 
not subject to any 12b-1 fees. See "No Load Alternative--Class D Shares." 

SELECTING A PARTICULAR CLASS. In deciding which Class of Fund shares to 
purchase, investors should consider the following factors, as well as any 
other relevant facts and circumstances: 

   The decision as to which Class of shares is more beneficial to an investor 
depends on the amount and intended length of his or her investment. Investors 
who prefer an initial sales charge alternative may elect to purchase Class A 
shares. Investors qualifying for significantly reduced or, in the case of 
purchases of $1 million or more, no initial sales charges may find Class A 
shares particularly attractive because similar sales charge reductions are 
not available with respect to Class B or Class C shares. Moreover, Class A 
shares are subject to lower ongoing expenses than are Class B or Class C 
shares over the term of the investment. As an alternative, Class B and Class 
C shares are sold without any initial sales charge so the entire purchase 
price is immediately invested in the Fund. Any investment return on these 
additional investment amounts may partially or wholly offset the higher 
annual expenses of these Classes. Because the Fund's future return cannot be 
predicted, however, there can be no assurance that this would be the case. 

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

   For the purpose of meeting the $5 million minimum investment amount for 
Class D shares, holdings of Class A shares in all Dean Witter Multi-Class 
Funds, shares of FSC Funds and shares of Dean Witter Funds for which such 
shares have been exchanged will be included together with the current 
investment amount. 

   Sales personnel may receive different compensation for selling each Class 
of shares. Investors should understand that the purpose of a CDSC is 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:

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 

                               12           
<PAGE>
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 Dean Witter Multi-Class Funds and shares of FSC Funds. The 
sales charge payable on the purchase of the Class A shares of the Fund, the 
Class A shares of the other Dean Witter Multi-Class Funds and the shares of 
the FSC Funds will be at their respective rates applicable to the total 
amount of the combined concurrent purchases of such shares. 

RIGHT OF ACCUMULATION. The above persons and entities may benefit from a 
reduction of the sales charges in accordance with the above schedule if the 
cumulative net asset value of Class A shares purchased in a single 
transaction, together with shares of the Fund and other Dean Witter Funds 
previously purchased at a price including a front-end sales charge (including 
shares of the Fund and other Dean Witter Funds acquired in exchange for those 
shares, and including in each case shares acquired through reinvestment of 
dividends and distributions), which are held at the time of such transaction, 
amounts to $25,000 or more. If such investor has a cumulative net asset value 
of shares of FSC Funds and Class A and Class D shares equal to at least $5 
million, such investor is eligible to purchase Class D shares subject to the 
$1,000 minimum initial investment requirement of that Class of the Fund. See 
"No Load Alternative--Class D Shares" below. 

   The Distributor must be notified by DWR or a Selected Broker-Dealer or the 
shareholder at the time a purchase order is placed that the purchase 
qualifies for the reduced charge under the Right of Accumulation. Similar 
notification must be made in writing by the dealer or shareholder when such 
an order is placed by mail. The reduced sales charge will not be granted if: 
(a) such notification is not furnished at the time of the order; or (b) a 
review of the records of the Selected Broker-Dealer or the Transfer Agent 
fails to confirm the investor's represented holdings. 

LETTER OF INTENT. The foregoing schedule of reduced sales charges will also 
be available to investors who enter into a written Letter of Intent providing 
for the purchase, within a thirteen-month period, of Class A shares of the 
Fund from DWR or other Selected Broker-Dealers. The cost of Class A shares of 
the Fund or shares of other Dean Witter Funds which were previously purchased 
at a price including a front-end sales charge during the 90-day period prior 
to the date of receipt by the Distributor of the Letter of Intent, or of 
Class A shares of the Fund or shares of other Dean Witter Funds acquired in 
exchange 

                               13           
<PAGE>
for shares of such funds purchased during such period at a price including a 
front-end sales charge, which are still owned by the shareholder, may also be 
included in determining the applicable reduction. 

ADDITIONAL NET ASSET VALUE PURCHASE OPTIONS. In addition to investments of $1 
million or more, Class A shares also may be purchased at net asset value by 
the following: 

   (1) trusts for which Dean Witter Trust Company ("DWTC") or Dean Witter 
Trust FSB ("DWTFSB") (each of which is an affiliate of the Investment 
Manager) provides discretionary trustee services; 

   (2) persons participating in a fee-based program approved by the

CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE--CLASS B SHARES 

Class B shares are sold at net asset value next determined without an initial 
sales charge so that the full amount of an investor's purchase payment may be 
immediately invested in the Fund. A CDSC, however, will be imposed on most 
Class B shares redeemed within six years after purchase. The CDSC will be 
imposed on any redemption of shares if after such redemption the aggregate 
current value of a Class B account with the Fund falls below the aggregate 
amount of the investor's purchase payments for Class B shares made during the 
six years (or, in the case of shares held by certain employer-sponsored 
benefit plans, three years) preceding the redemption. In addition, Class B 
shares are subject to an annual 12b-1 fee of 1.0% of the lesser of: (a) the 
average daily aggregate gross sales of the Fund's Class B shares since the 
inception of the Fund (not including reinvestments of dividends or capital 
gains distributions), less the average daily aggregate net asset value of the 
Fund's Class B shares redeemed since the Fund's inception upon which a CDSC 
has been imposed or waived, or (b) the average daily net assets of Class B. 

   Except as noted below, Class B shares of the Fund which are held for six 
years or more after purchase (calculated from the last day of the month in 
which the shares were purchased) will not be subject to any CDSC upon 
redemption. Shares redeemed earlier than six years after purchase may, 
however, be subject to a CDSC which will be a percentage of the dollar amount 
of shares redeemed and will be assessed on an amount equal to the lesser of 
the current market value or the cost of the shares being redeemed. The size 
of this percentage will depend upon how long the shares have been held, as 
set forth in the following table:

   In the case of Class B shares of the Fund held by 401 (k) plans or other 
employer-sponsored plans qualified under Section 401(a) of the Internal 
Revenue Code for which DWTC or DWTFSB serves as Trustee or the 401(k) Support 
Services Group of DWR serves as recordkeeper and whose accounts are opened on 
or after July 28, 1997, shares held for three years or more after purchase 
(calculated as described in the paragraph above) will not be subject to any 
CDSC upon redemption. However, shares redeemed earlier than three years after 
purchase may be subject to a CDSC (calculated as described in the paragraph 
above), the percentage of 

                               14

CDSC WAIVERS. A CDSC will not be imposed on: (i) any amount which represents 
an increase in value of shares purchased within the six years (or, in the 
case of shares held by certain employer-sponsored benefit plans, three years) 
preceding the redemption; (ii) the current net asset value of shares 
purchased more than six years (or, in the case of shares held by certain 
employer-sponsored benefit plans, three years) prior to the redemption; and 
(iii) the current net asset value of shares purchased through reinvestment of 
dividends or distributions and/or shares acquired in exchange for shares of 
FSC Funds or of other Dean Witter Funds acquired in exchange for such shares. 
Moreover, in determining whether a CDSC is applicable it will be assumed that 
amounts described in (i), (ii) and (iii) above (in that order) are redeemed 
first. In addition, no CDSC will be imposed on redemptions of shares which 
are attributable to reinvestment of dividends or distributions from, or the 
proceeds of, certain Unit Investment Trusts. 

   In addition, the CDSC, if otherwise applicable, will be waived in the case 
of: 

   (1) redemptions of shares held at the time a shareholder dies or becomes 
disabled, only if the shares are:   (A) registered either in the name of an 
individual shareholder (not a trust), or in the names of such shareholder and 
his or her spouse as joint tenants with right of survivorship; or   (B) held 
in a qualified corporate or self-employed retirement plan, Individual 
Retirement Account ("IRA") or Custodial Account under Section 403(b)(7) of 
the Internal Revenue Code ("403(b) Custodial Account"), provided in either 
case that the redemption is requested within one year of the death or initial 
determination of disability; 

   (2) redemptions in connection with the following retirement plan 
distributions:   (A) lump-sum or other distributions from a qualified 
corporate or self-employed retirement plan following retirement (or, in the 
case of a "key employee" of a "top heavy" plan, following attainment of age 
59 1/2);   (B) distributions from an IRA or 403(b) Custodial Account following 
attainment of age 59 1/2; or   (C) a tax-free return of an excess contribution 
to an IRA; and 

   (3) all redemptions of shares held for the benefit of a participant in a 
401(k) plan or other employer-sponsored plan qualified under Section 401(a) 
of the Internal Revenue Code which offers investment companies managed by the 
Investment Manager or its subsidiary, Dean Witter Services Company Inc., as 
self-directed investment alternatives and for which DWTC or DWTFSB serves as 
Trustee or the 401(k) Support Services Group of DWR serves as recordkeeper 
("Eligible Plan"), provided that either: (A) the plan continues to be an 
Eligible Plan after the redemption; or (B) the redemption is in connection 
with the complete termination of the plan involving the distribution of all 
plan assets to participants. 

   With reference to (1) above, for the purpose of determining disability, 
the Distributor utilizes the definition of disability contained in Section 
72(m)(7) of the Internal Revenue Code, which relates to the inability to 
engage in gainful employment. With reference to (2) above, the term 
"distribution" does not encompass a direct transfer of IRA, 403(b) Custodial 
Account or retirement plan assets to a successor custodian or trustee. All 
waivers will be granted only following receipt by the Distributor of 
confirmation of the shareholder's entitlement. 

<PAGE>

CONVERSION TO CLASS A SHARES. All shares of the Fund held prior to July 28, 
1997 have been designated Class B shares. Shares held before May 1, 1997 will 
convert to Class A shares in May, 2007. In all other instances Class B shares 
will convert automatically to Class A shares, based on the relative net asset 
values of the shares of the two Classes on the conversion date, which will be 
approximately ten (10) years after the date of the original purchase. The ten 
year period is calculated from the last day of the month in which the shares 
were purchased or, in the case of Class B shares acquired through an exchange 
or a series of exchanges, from the last day of the month in which the 
original Class B shares were purchased, provided that shares originally 
purchased before May 1, 1997 will convert to Class A shares in May, 2007. The 
conversion of shares purchased on or after May 1, 1997 will take place in the 
month following the tenth anniversary of the purchase. There will also be 
converted at that time such proportion of Class B shares acquired through 
automatic reinvestment of dividends and distributions owned by the 
shareholder as the total number of his or her Class B shares converting at 
the time bears to the total number of outstanding Class B shares purchased 
and owned by the shareholder. In the case of Class B shares held by a 401(k) 
plan or other employer-sponsored plan qualified under Section 401(a) of the 
Internal Revenue Code and for which DWTC or DWTFSB serves as Trustee or the 
401(k) Support Services Group of DWR serves as recordkeeper, the plan is 
treated as a single investor and all Class B shares will convert to Class A 
shares on the conversion date of the first shares of a Dean Witter 
Multi-Class Fund purchased by that plan. In the case of Class B shares 
previously exchanged for shares of an "Exchange Fund" (see "Shareholder 
Services--Exchange Privilege"), the period of time the shares were held in 
the Exchange Fund (calculated from the last day of the month in which the 
Exchange Fund shares were acquired) is excluded from the holding period for 
conversion. If those shares are 

                               15           
<PAGE>
subsequently re-exchanged for Class B shares of a Dean Witter Multi-Class 
Fund, the holding period resumes on the last day of the month in which Class 
B shares are reacquired. 

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

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

   Class B shares purchased before July 28, 1997 by trusts for which DWTC or 
DWTFSB provides discretionary trustee services will convert to Class A shares 
on or about August 29, 1997. The CDSC will not be applicable to such shares. 

LEVEL LOAD ALTERNATIVE--CLASS C SHARES 

Class C shares are sold at net asset value next determined without an initial 
sales charge but are subject to a CDSC of 1.0% on most redemptions made 
within one year after purchase (calculated from the last day of the month in 
which the shares were purchased). The CDSC will be assessed on an amount 
equal to the lesser of the current market value or the cost of the shares 
being redeemed. The CDSC will not be imposed in the circumstances set forth 
above in the section "Contingent Deferred Sales Charge Alternative--Class B 
Shares--CDSC Waivers," except that the references to six years in the first 
paragraph of that section shall mean one year in the case of Class C shares. 
Class C shares are subject to an annual 12b-1 fee of up to 1.0% of the 
average daily net assets of the Class. Unlike Class B shares, Class C shares 
have no conversion feature and, accordingly, an investor that purchases Class 
C shares will be subject to 12b-1 fees applicable to Class C shares for an 
indefinite period subject to annual approval by the Fund's Board of Trustees 
and regulatory limitations. 

NO LOAD ALTERNATIVE--CLASS D SHARES 

Class D shares are offered without any sales charge on purchase or redemption 
and without any 12b-1 fee. Class D shares are offered only to investors 
meeting an initial investment minimum of $5 million and the following 
categories of investors: (i) investors participating in the InterCapital 
mutual fund asset allocation program pursuant to which such persons pay an 
asset based fee; (ii) persons participating in a fee-based program approved 
by the Distributor, pursuant to which such persons pay an asset based fee for 
services in the nature of investment advisory or administrative services 
(subject to all of the terms and conditions of such programs, which may 
include termination fees and restrictions on transferability of Fund shares); 
(iii) 401(k) plans established by DWR and SPS Transaction Services, Inc. (an 
affiliate of DWR) for their employees; (iv) certain Unit Investment Trusts 
sponsored by DWR; (v) certain other open-end investment companies whose 
shares are distributed by the Distributor; and (vi) other categories of 
investors, at the discretion of the Board, as disclosed in the then current 
prospectus of the Fund. Investors who require a $5 million minimum initial 
investment to qualify to purchase Class D shares may satisfy that requirement 
by investing that amount in a single transaction in Class D shares of the 
Fund and other Dean Witter Multi-Class Funds, subject to the $1,000 minimum 
initial investment required for that Class of the Fund. In addition, for the 
purpose of meeting the $5 million minimum investment amount, holdings of 
Class A shares in all Dean Witter Multi-Class Funds, shares of FSC Funds and 
shares of Dean Witter Funds for which such shares have been exchanged will be 
included together with the current investment amount. If a shareholder 
redeems Class A shares and purchases Class D shares, such redemption may be a 
taxable event. 

PLAN OF DISTRIBUTION 

The Fund has adopted a Plan of Distribution pursuant to Rule 12b-1 under the 
Act with respect to the distribution of Class A, Class B and Class C shares 
of the Fund. In the case of Class A and Class C shares, the Plan provides 
that the Fund will reimburse the Distributor and others for the expenses of 
certain activities and services incurred by them specifically on behalf of 
those shares. Reimbursements for these expenses will be made in monthly 
payments by the Fund to the Distributor, which will in no event exceed 
amounts equal to payments at the annual rates of 0.25% and 1.0% of the 
average daily net assets of Class A and Class C, respectively. In the case of 
Class B shares, the Plan 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 

                               16           
<PAGE>
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 September 30, 1996, the Fund accrued payments 
under the Plan amounting to $6,461,408, which amount is equal to 1.0% of the 
Fund's average daily net assets for the fiscal year. The payments accrued 
under the Plan were calculated pursuant to clause (b) of the compensation 
formula under the Plan. All shares held prior to July 28, 1997 have been 
designated Class B shares. 

   In the case of Class B shares, at any given time, the expenses of 
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 redemption of Class B shares (see "Redemptions 
and Repurchases--Contingent Deferred Sales Charge"). 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 $28,270,501 at September 30, 1996, which was equal to 3.54% of the 
Fund's net assets on such date. Because there is no requirement under the 
Plan that the Distributor be reimbursed for all distribution expenses or any 
requirement that the Plan be continued from year to year, this excess amount 
does not constitute a liability of the Fund. Although there is no legal 
obligation for the Fund to pay expenses incurred in excess of payments made 
to the Distributor under the Plan and the proceeds of 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. No interest 
or other financing charges will be incurred on any Class A or Class C 
distribution expenses incurred by the Distributor under the Plan or on any 
unreimbursed expenses due to the Distributor pursuant to the Plan. 

DETERMINATION OF NET ASSET VALUE 

The net asset value per share is determined once daily at 4:00 p.m., New York 
time (or, on days when the New York Stock Exchange closes prior to 4:00 p.m., 
at such earlier time), on each day that the New York Stock Exchange is open 
by taking the net assets of the Fund, dividing by the number of shares 
outstanding and adjusting to the nearest cent. The assets belonging to the 
Class A, Class B, Class C and Class D shares will be invested together in a 
single portfolio. The net asset value of each Class, however, will be 
determined separately by subtracting each Class's accrued expenses and 
liabilities. The net asset value per share will not be determined on Good 
Friday and on such other federal and non-federal holidays as are observed by 
the New York Stock Exchange. 

   In the calculation of the Fund's net asset value: (1) an equity portfolio 
security listed or traded on the New York or American Stock Exchange or other 
domestic or foreign exchange is valued at its latest sale price on that 
exchange prior to the time assets are valued; if there were no sales that 
day, the security is valued at the latest bid price (in cases where a 
security is traded on more than one exchange, the security is valued on the 
exchange designated as the primary market pursuant to procedures adopted by 
the Trustees), and (2) all other portfolio securities for which 
over-the-counter market quotations are readily available are valued at the 
latest bid price. When market quotations are not readily available, including 
circumstances under which it is determined by the Investment Manager that 
sale and bid prices are not reflective of a security's market value, 
portfolio securities are valued at their fair value as determined in good 
faith under procedures established by and under the general supervision of 
the Board of Trustees (valuation of debt securities for which market 
quotations are not readily available may be based upon current market prices 
of securities which are comparable in coupon, rating and maturity or an 
appropriate matrix utilizing similar factors). 

                               17           
<PAGE>
   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 securitieswill be valued at their fair value as determined by the 
Trustees. 

   Certain of the Fund's portfolio securities may be valued by an outside 
pricing service approved by the Fund's Trustees. The pricing service may 
utilize a matrix system incorporating security quality, maturity and coupon 
as the evaluation model parameters, and/or research evaluations by its staff, 
including review of broker-dealer market price quotations, in determining 
what it believes is the fair valuation of the portfolio securities valued by 
such pricing service. 

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

AUTOMATIC INVESTMENT OF DIVIDENDS AND DISTRIBUTIONS. All income dividends and 
capital gains distributions are automatically paid in full and fractional 
shares of the applicable Class of the Fund (or, if specified by the 
shareholder, in shares of any other open-end Dean Witter Fund), unless the 
shareholder requests that they be paid in cash. Shares so acquired are 
acquired at net asset value and are not subject to the imposition of a 
front-end sales charge or a CDSC (see "Redemptions and Repurchases"). 

INVESTMENT OF DIVIDENDS AND DISTRIBUTIONS RECEIVED IN CASH. Any shareholder 
who receives a cash payment representing a dividend or capital gains 
distribution may invest such dividend or distribution in shares of the 
applicable Class at the net asset value per share next determined after 
receipt by the Transfer Agent, by returning the check or the proceeds to the 
Transfer Agent within thirty days after the payment date. Shares so acquired 
are acquired at net asset value and are not subject to the imposition of a 
front-end sales charge or a CDSC (see "Redemptions and Repurchases"). 

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

SYSTEMATIC WITHDRAWAL PLAN. A systematic withdrawal plan (the "Withdrawal 
Plan") is available for shareholders who own or purchase shares of the Fund 
having a minimum value of $10,000 based upon the then current net asset 
value. The Withdrawal Plan provides for monthly or quarterly (March, June, 
September and December) checks in any dollar amount, not less than $25, or in 
any whole percentage of the account balance, on an annualized basis. Any 
applicable CDSC will be imposed on shares redeemed under the Withdrawal Plan 
(see "Purchase of Fund Shares"). Therefore, any shareholder participating in 
the Withdrawal Plan will have sufficient shares redeemed from his or her 
account so that the proceeds (net of any applicable CDSC) to the shareholder 
will be the designated monthly or quarterly amount. Withdrawal plan payments 
should not be considered as dividends, yields or income. If periodic 
withdrawal plan payments continuously exceed net investment income and net 
capital gains, the shareholder's original investment will be correspondingly 
reduced and ultimately exhausted. Each withdrawal constitutes a redemption of 
shares and any gain or loss realized must be recognized for federal income 
tax purposes. 

   Shareholders should contact their DWR or other Selected Broker-Dealer 
account executive or the Transfer Agent for further information about any of 
the above services. 

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

   For further information regarding plan administration, 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 Dean Witter Multi-Class Fund without the imposition of any exchange 
fee. Shares may also be exchanged for shares of the following funds: Dean 
Witter Short-Term U.S. Treasury Trust, Dean Witter Limited Term Municipal 
Trust, Dean Witter Short-Term Bond Fund, Dean Witter Intermediate Term U.S. 
Treasury Trust and five Dean Witter funds which are money market funds (the 
"Exchange Funds"). Class A shares may also be exchanged for shares of Dean 
Witter Multi-State Municipal Series Trust and Dean Witter Hawaii Municipal 
Trust, which are Dean Witter Funds sold with a front-end sales charge ("FSC 
Funds"). Class B shares may also be exchanged for shares of Dean Witter 
Global Short-Term Income Fund Inc., Dean Witter High Income Securities and 
Dean Witter National Municipal Trust, which are Dean Witter Funds offered 
with a CDSC ("CDSC Funds"). Exchanges may be made after the shares of the 
Fund acquired by purchase (not by exchange or dividend reinvestment) have 
been held for 

                               18           
<PAGE>
thirty days. There is no waiting period for exchanges of shares acquired by 
exchange or dividend reinvestment. 

     An exchange to another Dean Witter Multi-Class Fund, any FSC Fund, any 
CDSC Fund or any Exchange Fund that is not a money market fund is on the 
basis of the next calculated net asset value per share of each fund after the 
exchange order is received. When exchanging into a money market fund from the 
Fund, shares of the Fund are redeemed out of the Fund at their next 
calculated net asset value and the proceeds of the redemption are used to 
purchase shares of the money market fund at their net asset value determined 
the following business day. Subsequent exchanges between any of the money 
market funds and any of the Dean Witter Multi-Class Funds, FSC Funds or CDSC 
Funds or any Exchange Fund that is not a money market fund can be effected on 
the same basis. 

   No CDSC is imposed at the time of any exchange of shares, although any 
applicable CDSC will be imposed upon ultimate redemption. During the period 
of time the shareholder remains in an Exchange Fund (calculated from the last 
day of the month in which the Exchange Fund shares were acquired), the 
holding period (for the purpose of determining the rate of the CDSC) is 
frozen. If those shares are subsequently re-exchanged for shares of a Dean 
Witter Multi-Class Fund or shares of a CDSC Fund, the holding period 
previously frozen when the first exchange was made resumes on the last day of 
the month in which shares of a Dean Witter Multi-Class Fund or shares of a 
CDSC Fund are reacquired. Thus, the CDSC is based upon the time (calculated 
as described above) the shareholder was invested in shares of a Dean Witter 
Multi-Class Fund or in shares of a CDSC Fund (see "Purchase of Fund Shares"). 
In the case of exchanges of Class A shares which are subject to a CDSC, the 
holding period also includes the time (calculated as described above) the 
shareholder was invested in shares of a FSC Fund. However, in the case of 
shares exchanged into an Exchange Fund on or after April 23, 1990, upon a 
redemption of shares which results in a CDSC being imposed, a credit (not to 
exceed the amount of the CDSC) will be given in an amount equal to the 
Exchange Fund 12b-1 distribution fees incurred on or after that date which 
are attributable to those shares. (Exchange Fund 12b-1 distribution fees are 
described in the prospectuses for those funds.) Class B shares of the Fund 
acquired in exchange for Class B shares of another Dean Witter Multi-Class 
Fund or shares of a CDSC Fund having a different CDSC schedule than that of 
this Fund will be subject to the higher CDSC schedule, even if such shares 
are subsequently re-exchanged for shares of the fund with the lower CDSC 
schedule. 

ADDITIONAL INFORMATION REGARDING EXCHANGES. Purchases and exchanges should be 
made for investment purposes only. A pattern of frequent exchanges may be 
deemed by the Investment Manager to be abusive and contrary to the best 
interests of the Fund's other shareholders and, at the Investment Manager's 
discretion, may be limited by the Fund's refusal to accept additional 
purchases and/or exchanges from the investor. Although the Fund does not have 
any specific definition of what constitutes a pattern of frequent exchanges, 
and will consider all relevant factors in determining whether a particular 
situation is abusive and contrary to the best interests of the Fund and its 
other shareholders, investors should be aware that the Fund and each of the 
other Dean Witter Funds may in their discretion limit or otherwise restrict 
the number of times this Exchange Privilege may be exercised by any investor. 
Any such restriction will be made by the Fund on a prospective basis only, 
upon notice to the shareholder not later than ten days following such 
shareholder's most recent exchange. Also, the Exchange Privilege may be 
terminated or revised at any time by the Fund and/or any of such Dean Witter 
Funds for which shares of the Fund have been exchanged, upon such notice as 
may be required by applicable regulatory agencies. Shareholders maintaining 
margin accounts with DWR or another Selected Broker-Dealer are referred to 
their account executive regarding restrictions on exchange of shares of the 
Fund pledged in the margin account. 

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

   If DWR or another Selected Broker-Dealer is the current dealer of record 
and its account numbers are part of the account information, shareholders may 
initiate an exchange of shares of the Fund for shares of any of the Dean 
Witter Funds (for which the Exchange Privilege is available) pursuant to this 
Exchange Privilege by contacting their account executive (no Exchange 
Privilege Authorization Form is required). Other shareholders (and those 
shareholders who are clients of DWR or another Selected Broker-Dealer but who 
wish to make exchanges directly by writing or telephoning the Transfer Agent) 
must complete and forward to the Transfer Agent an Exchange Privilege 
Authorization Form, copies of which may be obtained from the Transfer Agent, 
to initiate an exchange. If the Authorization Form is used, exchanges may be 
made in writing or by contacting the Transfer Agent at (800) 869-NEWS 
(toll-free). 

                               19

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

   Telephone exchange instructions will be accepted if received by the 
Transfer Agent between 9:00 a.m. and 4:00 p.m., New York time, on any day the 
New York Stock Exchange is open. Any shareholder wishing to make an exchange 
who has previously filed an Exchange Privilege Authorization Form and who is 
unable to reach the Fund by telephone should contact his or her DWR or other 
Selected Broker-Dealer account executive, if appropriate, or make a written 
exchange request. Shareholders are advised that during periods of drastic 
economic or market changes, it is possible that the telephone exchange 
procedures may be difficult to implement, although this has not been the case 
with the Dean Witter Funds in the past. 

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

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

REDEMPTION. Shares of each Class of the Fund can be redeemed for cash at any 
time at the net asset value per share next determined less the amount of any 
applicable CDSC in the case of Class A, Class B or Class C shares (see 
"Purchase of Fund Shares"). If shares are held in a shareholder's account 
without a share certificate, a written request for redemption to the Fund's 
Transfer Agent at P.O. Box 983, Jersey City, NJ 07303 is required. If 
certificates are held by the shareholder, the shares may be redeemed by 
surrendering the certificates with a written request for redemption, along 
with any additional information required by the Transfer Agent. 

REPURCHASE. DWR and other Selected Broker-Dealers are authorized to 
repurchase shares represented by a share certificate which is delivered to 
any of their offices. Shares held in a shareholder's account without a share 
certificate may also be repurchased by DWR and other Selected Broker-Dealers 
upon the telephonic request of the shareholder. The repurchase price is the 
net asset value next computed (see "Purchase of Fund Shares") after such 
purchase 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, the 
Distributor, DWR or other Selected Broker-Dealers. The offer by DWR and other 
Selected Broker-Dealers to repurchase shares may be suspended without notice 
by them at any time. In that event, shareholders may redeem their shares 
through the Fund's Transfer Agent as set forth above under "Redemption." 

PAYMENT FOR SHARES REDEEMED OR REPURCHASED. Payment for shares presented for 
repurchase or redemption will be made by check within seven days after 
receipt by the Transfer Agent of the certificate and/or written request in 
good order. Such payment may be postponed or the right of redemption 
suspended under unusual circumstances, e.g., when normal trading is not 
taking place on the New York Stock Exchange. If the shares to be redeemed 
have recently been purchased by check, payment of the redemption proceeds may 
be delayed for the minimum time needed to verify that the check used for 
investment has been honored (not more than fifteen days from the time of 
receipt of the check by the Transfer Agent). Shareholders maintaining margin 
accounts with DWR or another Selected Broker-Dealer are referred to their 
account executives regarding restrictions on redemption of shares of the Fund 
pledged in the margin account. 

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

INVOLUNTARY REDEMPTION. The Fund reserves the right, on sixty days' notice, 
to redeem, at their net asset value, the shares of any shareholder (other 
than shares held in an Individual Retirement Account or custodial account 
under Section 403(b)(7) of the Internal Revenue Code) whose shares due to 
redemptions by the shareholder have a value of less than $100, or such lesser 
amount as may be fixed by the Board of 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 sixty days to make an additional 
investment in an amount which will increase the value of his or her account 
to at least the applicable amount before the redemption is processed. No CDSC 
will be imposed on any involuntary redemption.

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

DIVIDENDS AND DISTRIBUTIONS. The Fund declares dividends separately for each 
Class of shares and intends to distribute substantially all of its 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 to retain all 
or part of any net long-term capital gains in any year for reinvestment. 

   All dividends and any capital gains distributions will be paid in 
additional shares of the same Class and automatically credited to the 
shareholder's account without issuance of a share certificate unless the 
shareholder requests in writing that all dividends and/or distributions be 
paid in cash. Shares acquired by dividend and distribution reinvestments will 
not be subject to any front-end sales charge or CDSC. Class B shares acquired 
through dividend and distribution reinvestments will become eligible for 
conversion to Class A shares on a pro rata basis. Distributions paid on Class 
A and Class D shares will be higher than for Class B and Class C shares 
because distribution fees paid by Class B and Class C shares are higher. (See 
"Shareholder Services-- Automatic Investment of Dividends and 
Distributions.") 

TAXES. Because the Fund intends to distribute all of its net investment 
income and net capital gains (to the extent not offset by capital loss 
carryovers) to shareholders and remain qualified as a regulated investment 
company under Subchapter M of the Internal Revenue Code, it is not expected 
that the Fund will be required to pay any federal income tax. Shareholders 
who are required to pay taxes on their income will normally have to pay 
federal income taxes, and any state income taxes, on any dividends and 
distributions they receive from the Fund. Such dividends and distributions, 
to the extent they are derived from net investment income and net short-term 
capital gains, are taxable to the shareholder as ordinary dividend income 
regardless of whether the shareholder receives such payments in additional 
shares or in cash. All dividends declared in the last quarter of any calendar 
year which are paid in the following year prior to February 1 will be deemed, 
for tax purposes, to have been received by the shareholder in the prior year. 

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

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

   After the end of the calendar year, shareholders will receive full 
information on their dividends and capital gains distributions for tax 
purposes. To avoid being subject to a 31% federal backup withholding tax on 
taxable dividends, capital gains distributions and the proceeds of 
redemptions and repurchases, shareholders' taxpayer identification numbers 
must be furnished and certified as to 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. 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 will 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, 
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 the 
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 property of the 
Fund 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. Directors, officers and employees of InterCapital, Dean 
Witter Services Company Inc. and the Distributor are subject to a strict Code 
of Ethics adopted by those companies. The Code of Ethics is intended to 
ensure that the interests of shareholders and other clients are placed ahead 
of any personal interest, that no undue personal benefit is obtained from a 
person's employment activities and that actual and potential conflicts of 
interest are avoided. To achieve these goals and comply with regulatory 
requirements, the Code of Ethics requires, among other things, that personal 
securities transactions by employees of the companies be subject to an 
advance clearance process to monitor that no Dean Witter Fund is engaged at 
the same time in a purchase or sale of the same security. The Code of Ethics 
bans the purchase of securities in an initial public offering, and also 
prohibits engaging in futures and options transactions and profiting on 
short-term trading (that is, a purchase within sixty days of a sale or a sale 
within sixty days of a purchase) of a security. In addition, investment 
personnel may not purchase or sell a security for their personal account 
within thirty days before or after any transaction in any Dean Witter Fund 
managed by them. Any violations of the Code of Ethics are subject to 
sanctions, including reprimand, demotion or suspension or termination of 
employment. The Code of Ethics comports with regulatory requirements and the 
recommendations in the 1994 report by the Investment Company Institute 
Advisory Group on Personal Investing. 

MASTER/FEEDER CONVERSION. The Fund reserves the right to seek to achieve its 
investment objective by investing all of its investable assets in a 
diversified, open-end management investment company having the same 
investment objective and policies and substantially the same investment 
restrictions as those applicable to the Fund. 

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