Dean Witter Developing Growth Securities Trust (the "Fund") is an open-end 
diversified management investment company whose investment objective is 
long-term capital growth. While the Fund may invest in all types of equity 
and debt securities, it invests primarily in common stocks of smaller and 
medium-sized companies that, in the opinion of the Investment Manager, have 
the potential for growing more rapidly than the economy and which may benefit 
from new products or services, technological developments or changes in 
management. (See "Investment Objective and Policies.") 

   
The Fund offers four classes of shares (each, a "Class"), each with a 
different combination of sales charges, ongoing fees and other features. The 
different distribution arrangements permit an investor to choose the method 
of purchasing shares that the investor believes is most beneficial given the 
amount of the purchase, the length of time the investor expects to hold the 
shares and other relevant circumstances. Shares of the Fund held prior to 
July 28, 1997 have been designated Class B shares. (See "Purchase of Fund 
Shares--Alternative Purchase Arrangements.") 

This Prospectus sets forth concisely the information you should know before

Alternative       Four classes of shares are offered: 
Purchase          o Class A shares are offered with a front-end sales charge, starting at 5.25% and reduced for 
Arrangements      larger purchases. Investments of $1 million or more (and investments by certain other limited 
                  categories of investors) are not subject to any sales charge at the time of purchase but a 
                  contingent deferred sales charge ("CDSC") of 1.0% may be imposed on redemptions within one year 
                  of purchase. The Fund is authorized to reimburse the Distributor for specific expenses incurred 
                  in promoting the distribution of the Fund's Class A shares and servicing shareholder accounts 
                  pursuant to the Fund's 12b-1 Plan. Reimbursement may in no event exceed an amount equal to 
                  payments at an annual rate of 0.25% of average daily net assets of the Class (see pages 14, 17 
                  and 23). 

                  o Class B shares are offered without a front-end sales charge, but will in most cases be subject 
                  to a CDSC (scaled down from 5.0% to 1.0%) if redeemed within six years after purchase. The CDSC 
                  will be imposed on any redemption of shares if after such redemption the aggregate current value 
                  of a Class B account with the Fund falls below the aggregate amount of the investor's purchase 
                  payments made during the six years preceding the redemption. A different CDSC schedule applies 
                  to investments by certain qualified plans. Class B shares are also subject to a 12b-1 fee 
                  assessed at the annual rate of 1.0% of the lesser of: (a) the average daily net sales of the 
                  Fund's Class B shares or (b) the average daily net assets of Class B. All shares of the Fund 
                  held prior to July 28, 1997 have been designated Class B shares. Shares held before May 1, 1997 
                  will convert to Class A shares in May, 2007. In all other instances, Class B shares convert to 
                  Class A shares approximately ten years after the date of the original purchase (see pages 14, 19 
                  and 23). 

                  o Class C shares are offered without a front-end sales charge, but will in most cases be subject 
                  to a CDSC of 1.0% if redeemed within one year after purchase. The Fund is authorized to 
                  reimburse the Distributor for specific expenses incurred in promoting the distribution of the 
                  Fund's Class C shares and servicing shareholder accounts pursuant to the Fund's 12b-1 Plan. 
                  Reimbursement may in no event exceed an amount equal to payments at an annual rate of 1.0% of 
                  average daily net assets of the Class (see pages 14, 22 and 23). 

                  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 14, 22 and 23).

Dividends and     Dividends from net investment income and distributions from net capital gains, if any, are paid 
Capital Gains     at least once per year. Dividends and capital gains distributions are automatically reinvested 
Distributions     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 24 and 28). 
- ----------------- ------------------------------------------------------------------------------------------------ 
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 27). 
- ----------------- ------------------------------------------------------------------------------------------------ 
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 9-12).

SUMMARY OF FUND EXPENSES 
- -----------------------------------------------------------------------------

- ------------ 
(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 annually 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 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. 

                                8           
<PAGE>
   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 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 on foreign markets than in the U.S. In 
addition, differences in clearance and settlement procedures in 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 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 

                               10           
<PAGE>
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 

                               11           
<PAGE>
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 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 empha- 

                               12           
<PAGE>
   
sis 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, 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 

                               13           
<PAGE>

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 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 
    

                               14           
<PAGE>
   
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." 
    

                               15           
<PAGE>
   
   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 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 theFund'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 
    

                               16           
<PAGE>
   
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:

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

INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES 

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

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

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

   The above schedule of sales charges is applicable to purchases in a single 
transaction by, among others: (a) an individual; (b) an individual, his or 
her spouse and their children under the age of 21 purchasing shares for his, 
her or their own accounts; (c) a trustee or other fiduciary purchasing shares 
for a single trust estate or a single fiduciary account; (d) a pension, 
profit-sharing or other employee benefit plan qualified or non-qualified 
under Section 401 of the Internal Revenue Code; (e) tax-exempt organizations 
enumerated in Section 501(c)(3) or (13) of the Internal Revenue Code; (f) 
employee benefit plans qualified under Section 401 of the Internal Revenue 
Code of a single employer or of employers who are "affiliated persons" of 
each other within the meaning of Section 2(a)(3)(c) of the Act; and for 
investments in Individual Retirement Accounts of employees of a single 
employer through Systematic Payroll Deduction plans; or (g) any other 
organized group of persons, whether incorporated or not, provided the 
organization has been in existence for at least six months and has some 
purpose other than the purchase of redeemable securities of a registered 
investment company at a discount. 

   Combined Purchase Privilege. Investors may have the benefit of reduced 
sales charges in accordance with the above schedule by combining purchases of 
Class A shares of the Fund in single transactions with the purchase of Class 
A shares of other 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. 
    

                               18           
<PAGE>
   
   Letter of Intent. The foregoing schedule of reduced sales charges will 
also be available to investors who enter into a written Letter of Intent 
providing for the purchase, within a thirteen-month period, of Class A shares 
of the Fund from DWR or other Selected Broker-Dealers. The cost of Class A 
shares of the Fund or shares of other Dean Witter Funds which were previously 
purchased at a price including a front-end sales charge during the 90-day 
period prior to the date of receipt by the Distributor of the Letter of 
Intent, or of Class A shares of the Fund or shares of other Dean Witter Funds 
acquired in exchange for shares of such funds purchased during such period at 
a price including a front-end sales charge, which are still owned by the 
shareholder, may also be included in determining the applicable reduction. 

   Additional Net Asset Value Purchase Options. In addition to investments of 
$1 million or more, Class A shares also may be purchased at net asset value 
by the following: 

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

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

   (3) retirement plans qualified under Section 401(k) of the Internal 
Revenue Code ("401(k) plans") and other employer-sponsored plans qualified 
under Section 401(a) of the Internal Revenue Code with at least 200 eligible 
employees and for which DWTC or DWTFSB serves as Trustee or the 401(k) 
Support Services Group of DWR serves as recordkeeper; 

   (4) 401(k) plans and other employer-sponsored plans qualified under 
Section 401(a) of the Internal Revenue Code for which DWTC or DWTFSB serves 
as Trustee or the 401(k) Support Services Group of DWR serves as recordkeeper 
whose Class B shares have converted to Class A shares, regardless of the 
plan's asset size or number of eligible employees; 

   (5) investors who are clients of a Dean Witter account executive who 
joined Dean Witter from another investment firm within six months prior to 
the date of purchase of Fund shares by such investors, if the shares are 
being purchased with the proceeds from a redemption of shares of an open-end 
proprietary mutual fund of the account executive's previous firm which 
imposed either a front-end or deferred sales charge, provided such purchase 
was made within sixty days after the redemption and the proceeds of the 
redemption had been maintained in the interim in cash or a money market fund; 
and 

   (6) other categories of investors, at the discretion of the Board, as 
disclosed in the then current prospectus of the Fund. 

   No CDSC will be imposed on redemptions of shares purchased pursuant to 
paragraphs (1), (2) or (5), above. 

   For further information concerning purchases of the Fund's shares, contact 
DWR or another Selected Broker-Dealer or consult the Statement of Additional 
Information. 

CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE--CLASS B SHARES 

   Class B shares are sold at net asset value next determined without an 
initial sales charge so that the full amount of an investor's purchase 
payment may be immediately invested in the Fund. A CDSC, however, will be 
imposed on most Class B shares redeemed within six years after purchase. The 
CDSC will be imposed on any redemption of shares if after such redemption the 
aggregate current value of a Class B account with the Fund falls below the 
aggregate amount of the investor's purchase payments for Class B shares made 
during the six years (or, in the case of shares held by certain 
employer-sponsored benefit plans, three years) preceding the 
    

                               19           
<PAGE>
   
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 which will depend on how long the shares have been 
held, as set forth in the following table:

   CDSC Waivers. A CDSC will not be imposed on: (i) any amount which 
represents an increase in value of shares purchased within the six years (or, 
in the case of shares held by certain 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 
    

                               20

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. 

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

                               21           
<PAGE>
   
   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 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, 
    

                               23           
<PAGE>
   
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). 

   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 
share- 
    

                               24           
<PAGE>
   
holder 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 
    

                               25           
<PAGE>
reinvestment) have been held for thirty days. There is no waiting period for 
exchanges of shares acquired by exchange or dividend reinvestment. 

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

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

   Additional Information Regarding Exchanges. Purchases and exchanges should 
be made for investment purposes only. A pattern of frequent exchanges may be 
deemed by the Investment Manager to be abusive and contrary to the best 
interests of the Fund's other shareholders and, at the Investment Manager's 
discretion, may be limited by the Fund's refusal to accept additional 
purchases and/or exchanges from the investor. Although the Fund does not have 
any specific definition of what constitutes a pattern of frequent exchanges, 
and will consider all relevant factors in determining whether a particular 
situation is abusive and contrary to the best interests of the Fund and its 
other shareholders, investors should be aware that the Fund and each of the 
other Dean Witter Funds may in their discretion limit or otherwise restrict 
the number of times this Exchange Privilege may be exercised by any investor. 
Any such restriction will be made by 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 care- 

                               26           
<PAGE>
   
fully 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). 
    

   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") 

                               27           
<PAGE>
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 

                               28           
    
<PAGE>
   
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.

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

THE FUND 

   The Fund was organized under the laws of the Commonwealth of Massachusetts 
on December 28, 1982 and is a trust of the type commonly known as a 
"Massachusetts Business Trust." 

THE INVESTMENT MANAGER 

   
   Dean Witter InterCapital Inc. (the "Investment Manager" or 
"InterCapital"), a Delaware corporation, whose address is Two World Trade 
Center, New York, New York, 10048, is the Fund's investment manager. 
InterCapital is a wholly-owned subsidiary of Morgan Stanley, Dean Witter, 
Discover & Co. ("MSDWD"), a Delaware corporation. In an internal 
reorganization which took place in January, 1993, InterCapital assumed the 
investment advisory, administrative and management activities previously 
performed by the InterCapital Division of Dean Witter Reynolds Inc. ("DWR"), 
a broker-dealer affiliate of InterCapital. (As hereinafter used in this 
Statement of Additional Information, the terms "InterCapital" and "Investment 
Manager" refer to DWR's InterCapital Division prior to the internal 
reorganization and Dean Witter InterCapital Inc. thereafter.) The daily 
management of the Fund and research relating to the Fund's portfolio are 
conducted by or under the direction of officers of the Fund and of the 
Investment Manager, subject to review by the Fund's Board of Trustees. In 
addition, Trustees of the Fund provide guidance on economic factors and 
interest rate trends. Information as to these Trustees and officers is 
contained under the caption "Trustees and Officers."

Municipal Income Opportunities Trust III, Municipal Premium Income Trust and 
Prime Income Trust. The foregoing investment companies, together with the 
Fund, are collectively referred to as the Dean Witter Funds. 

   
   In addition, Dean Witter Services Company Inc. ("DWSC"), a wholly-owned 
subsidiary of InterCapital, serves as manager for the following companies for 
which TCW Funds Management, Inc. is the investment adviser: TCW/DW Core 
Equity Trust, TCW/DW North American Government Income Trust, TCW/DW Latin 
American Growth Fund, TCW/DW Income and Growth Fund, TCW/DW Small Cap Growth 
Fund, TCW/DW Balanced Fund, TCW/DW Total Return Trust, TCW/DW Mid-Cap Equity 
Trust, TCW/DW Global Telecom Trust, TCW/DW Strategic Income Trust, TCW/DW 
Emerging Markets Opportunities Trust, TCW/DW Term Trust 2000, TCW/DW Term 
Trust 2002 and TCW/DW Term Trust 2003 (the "TCW/DW Funds"). InterCapital also 
serves as: (i) administrator of The BlackRock Strategic Term Trust Inc., a 
closed-end investment company; and (ii) sub-administrator of MassMutual 
Participation Investors and Templeton Global Governments Income Trust, 
closed-end investment companies. 
    

   Pursuant to an Investment Management Agreement (the "Agreement") with the 
Investment Manager, the Fund has retained the Investment Manager to manage 
the investment of the Fund's assets, including the placing of orders for the 
purchase and sale of portfolio securities. The Investment Manager obtains and 
evaluates such information and advice relating to the economy, securities 
markets, and specific securities as it considers necessary or useful to 
continuously manage the assets of the Fund in a manner consistent with its 
investment objective and policies. 

   Under the terms of the Agreement, in addition to managing the Fund's 
investments, the Investment Manager maintains certain of the Fund's books and 
records and furnishes, at its own expense, such office space, facilities, 
equipment, clerical help, bookkeeping and certain legal services as the Fund 
may reasonably require in the conduct of its business, including the 
preparation of prospectuses, proxy statements and reports required to be 
filed with federal and state securities commissions (except insofar as the 
participation or assistance of independent accountants and attorneys is, in 
the opinion of the Investment Manager, necessary or desirable). In addition, 
the Investment Manager pays the salaries of all personnel, including officers 
of the Fund, who are employees of the Investment Manager. The Investment 
Manager also bears the cost of telephone service, heat, light, power and 
other utilities provided to the Fund. 

   Effective December 31, 1993, pursuant to a Services Agreement between 
InterCapital and DWSC, DWSC began to provide the administrative services to 
the Fund which were previously performed directly by InterCapital. On April 
17, 1995, DWSC was reorganized in the State of Delaware, necessitating the 
entry into a new Services Agreement by InterCapital and DWSC on that date. 
The foregoing internal reorganizations did not result in any change in the 
nature or scope of the administrative services being provided to the Fund or 
any of the fees being paid by the Fund for the overall services being 
performed under the terms of the existing Agreement. 

   
   Expenses not expressly assumed by the Investment Manager under the 
Agreement or by the Distributor of the Fund's shares, Dean Witter 
Distributors Inc. ("Distributors" or the "Distributor") (see "The 
Distributor"), will be paid by the Fund. These expenses will be allocated 
among the four classes of shares of the Fund (each, a "Class") pro rata based 
on the net assets of the Fund attributable to each Class, except as described 
below. The expenses borne by the Fund include, but are not limited to: 
expenses of the Plan of Distribution pursuant to Rule 12b-1 (the "12b-1 fee") 
(see "The Distributor"); charges and expenses of any registrar, custodian, 
share transfer and dividend disbursing agent; brokerage commissions; taxes; 
engraving and printing share certificates; registration costs of the Fund and 
its shares under federal and state securities laws; the cost and expenses of 
printing, including typesetting, and distributing prospectuses of the Fund 
and supplements thereto to the Fund's shareholders; all expenses of 
shareholders' and Trustees' meetings and of preparing, printing and mailing 
proxy statements and reports to shareholders; fees and travel expenses of 
Trustees or members of any advisory board or committee who are not employees 
of the Investment Manager or any corporate affiliate of the Investment 
Manager; all expenses incident to any dividend, withdrawal or redemption 
options; charges and expenses of any outside service used for pricing of the 
Fund's shares; fees and 
    

                                4           
<PAGE>
   
expenses of legal counsel, including counsel to the Trustees who are not 
interested persons of the Fund or of the Investment Manager (not including 
compensation or expenses of attorneys who are employees of the Investment 
Manager) and independent accountants; membership dues of industry 
associations; interest on Fund borrowings; postage; insurance premiums on 
property or personnel (including officers and Trustees) of the Fund which 
inure to its benefit; extraordinary expenses (including, but not limited to, 
legal claims and liabilities and litigation costs and any indemnification 
relating thereto); and all other costs of the Fund's operation. The 12b-1 
fees relating to a particular Class will be allocated directly to that Class. 
In addition, other expenses associated with a particular Class (except 
advisory or custodial fees) may be allocated directly to that Class, provided 
that such expenses are reasonably identified as specifically attributable to 
that Class and the direct allocation to that Class is approved by the 
Trustees. 
    

   As full compensation for the services and facilities furnished to the Fund 
and expenses of the Fund assumed by the Investment Manager, the Fund pays the 
Investment Manager monthly compensation calculated daily by applying the 
following annual rates to the Fund's daily net assets: 0.50% of the portion 
of the daily net assets not exceeding $500 million and 0.475% of the portion 
of the daily net assets exceeding $500 million. For the fiscal years ended 
September 30, 1994, 1995 and 1996, the Fund accrued to the Investment Manager 
total compensation in the amounts of $1,515,547, $1,916,827 and $3,194,151, 
respectively. 

   The Agreement provides that in the absence of willful misfeasance, bad 
faith, gross negligence or reckless disregard of its obligations thereunder, 
the Investment Manager is not liable to the Fund or any of its investors for 
any act or omission by the Investment Manager or for any losses sustained by 
the Fund or its investors. The Agreement in no way restricts the Investment 
Manager from acting as investment manager or adviser to others. 

   
   The Agreement was initially approved by the Board of Trustees on February 
21, 1997 and by the shareholders of the Fund at a Special Meeting of 
Shareholders held on May 21, 1997. The Agreement is substantially identical 
to a prior investment management agreement which was initially approved by 
the Board of Trustees on October 30, 1992 and by the shareholders of the Fund 
at a Special Meeting of Shareholders held on January 12, 1993. The Agreement 
took effect on May 31, 1997 upon the consummation of the merger of Dean 
Witter, Discover & Co. with Morgan Stanley Group Inc. The Agreement may be 
terminated at any time, without penalty, on thirty days' notice by the Board 
of Trustees of the Fund, by the holders of a majority, as defined in the 
Investment Company Act of 1940 (the "Act"), of the outstanding shares of the 
Fund, or by the Investment Manager. The Agreement will automatically 
terminate in the event of its assignment (as defined in the Act). 

   Under its terms, the Agreement has an initial term ending April 30, 1999, 
and will remain in effect from year to year thereafter, provided continuance 
of the Agreement is approved at least annually by the vote of the holders of 
a majority, as defined in the Act, of the outstanding shares of the Fund, or 
by the Board of Trustees of the Fund; provided that in either event such 
continuance is approved annually by the vote of a majority of the Trustees of 
the Fund who are not parties to the Agreement or "interested persons" (as 
defined in the Act) of any such party (the "Independent Trustees"), which 
vote must be cast in person at a meeting called for the purpose of voting on 
such approval. 
    

   The Fund has acknowledged that the name "Dean Witter" is a property right 
of DWR. The Fund has agreed that DWR or its parent company may use or, at any 
time, permit others to use, the name "Dean Witter." The Fund has also agreed 
that in the event the Agreement is terminated, or if the affiliation between 
InterCapital and its parent company is terminated, the Fund will eliminate 
the name "Dean Witter" from its name if DWR or its parent company shall so 
request.

THE BOARD OF TRUSTEES, THE INDEPENDENT TRUSTEES, AND THE COMMITTEES 

   
   The Board of Trustees currently consists of eight (8) trustees; as noted 
above, Mr. Hedien's term will commence on September 1, 1997. These same 
individuals also serve as directors or trustees for all of the Dean Witter 
Funds, and are referred to in this section as Trustees. As of the date of 
this Statement of Additional Information, there are a total of 83 Dean Witter 
Funds, comprised of 126 portfolios. As of June 30, 1997, the Dean Witter 
Funds had total net assets of approximately $87.9 billion and more than six 
million shareholders. 

   Six Trustees and Mr. Hedien (77% of the total number) have no affiliation 
or business connection with InterCapital or any of its affiliated persons and 
do not own any stock or other securities issued by InterCapital's parent 
company, MSDWD. These are the "disinterested" or "independent" Trustees. The 
other two Trustees (the "management Trustees") are affiliated with 
InterCapital. Four of the six independent Trustees are also Independent 
Trustees of the TCW/DW Funds. 
    

                                8           
<PAGE>
   Law and regulation establish both general guidelines and specific duties 
for the Independent Trustees. The Dean Witter Funds seek as Independent 
Trustees individuals of distinction and experience in business and finance, 
government service or academia; these are people whose advice and counsel are 
in demand by others and for whom there is often competition. To accept a 
position on the Funds' Boards, such individuals may reject other attractive 
assignments because the Funds make substantial demands on their time. Indeed, 
by serving on the Funds' Boards, certain Trustees who would otherwise be 
qualified and in demand to serve on bank boards would be prohibited by law 
from doing so. 

   
   All of the current Independent Trustees serve as members of the Audit 
Committee and the Committee of the Independent Trustees. Three of them also 
serve as members of the Derivatives Committee. During the calendar year ended 
December 31, 1996, the three Committees held a combined total of sixteen 
meetings. The Committees hold some meetings at InterCapital's offices and 
some outside InterCapital. Management Trustees or officers do not attend 
these meetings unless they are invited for purposes of furnishing information 
or making a report. 
    

   The Committee of the Independent Trustees is charged with recommending to 
the full Board approval of management, advisory and administration contracts, 
Rule 12b-1 plans and distribution and underwriting agreements; continually 
reviewing Fund performance; checking on the pricing of portfolio securities, 
brokerage commissions, transfer agent costs and performance, and trading 
among Funds in the same complex; and approving fidelity bond and related 
insurance coverage and allocations, as well as other matters that arise from 
time to time. The Independent Trustees are required to select and nominate 
individuals to fill any Independent Trustee vacancy on the Board of any Fund 
that has a Rule 12b-1 plan of distribution. Most of the Dean Witter Funds 
have such a plan. 

   The Audit Committee is charged with recommending to the full Board the 
engagement or discharge of the Fund's independent accountants; directing 
investigations into matters within the scope of the independent accountants' 
duties, including the power to retain outside specialists; reviewing with the 
independent accountants the audit plan and results of the auditing 
engagement; approving professional services provided by the independent 
accountants and other accounting firms prior to the performance of such 
services; reviewing the independence of the independent accountants; 
considering the range of audit and non-audit fees; reviewing the adequacy of 
the Fund's system of internal controls; and preparing and submitting 
Committee meeting minutes to the full Board. 

   Finally, the Board of each Fund has formed a Derivatives Committee to 
establish parameters for and oversee the activities of the Fund with respect 
to derivative investments, if any, made by the Fund. 

DUTIES OF CHAIRMAN OF COMMITTEE OF THE INDEPENDENT TRUSTEES AND AUDIT 
COMMITTEE 

   The Chairman of the Committee of the Independent Trustees and the Audit 
Committee maintains an office at the Funds' headquarters in New York. He is 
responsible for keeping abreast of regulatory and industry developments and 
the Funds' operations and management. He screens and/or prepares written 
materials and identifies critical issues for the Independent Trustees to 
consider, develops agendas for Committee meetings, determines the type and 
amount of information that the Committees will need to form a judgment on 
various issues, and arranges to have that information furnished to Committee 
members. He also arranges for the services of independent experts and 
consults with them in advance of meetings to help refine reports and to focus 
on critical issues. Members of the Committees believe that the person who 
serves as Chairman of both Committees and guides their efforts is pivotal to 
the effective functioning of the Committees. 

   The Chairman of the Committees also maintains continuous contact with the 
Funds' management, with independent counsel to the Independent Trustees and 
with the Funds' independent auditors. He arranges for a series of special 
meetings involving the annual review of investment advisory, management and 
other operating contracts of the Funds and, on behalf of the Committees, 
conducts negotiations with the Investment Manager and other service 
providers. In effect, the Chairman of the Committees serves as a combination 
of chief executive and support staff of the Independent Trustees. 

   The Chairman of the Committee of the Independent Trustees and the Audit 
Committee is not employed by any other organization and devotes his time 
primarily to the services he performs as

<PAGE>
Committee Chairman and Independent Trustee of the Dean Witter Funds and as an 
Independent Trustee and, since July 1, 1996, as Chairman of the Committee of 
the Independent Trustees and the Audit Committee of the TCW/DW Funds. The 
current Committee Chairman has had more than 35 years experience as a senior 
executive in the investment company industry. 

ADVANTAGES OF HAVING SAME INDIVIDUALS AS INDEPENDENT TRUSTEES FOR ALL DEAN 
WITTER FUNDS 

   The Independent Trustees and the Funds' management believe that having the 
same Independent Trustees for each of the Dean Witter Funds avoids the 
duplication of effort that would arise from having different groups of 
individuals serving as Independent Trustees for each of the Funds or even of 
sub-groups of Funds. They believe that having the same individuals serve as 
Independent Trustees of all the Funds tends to increase their knowledge and 
expertise regarding matters which affect the Fund complex generally and 
enhances their ability to negotiate on behalf of each Fund with the Fund's 
service providers. This arrangement also precludes the possibility of 
separate groups of Independent Trustees arriving at conflicting decisions 
regarding operations and management of the Funds and avoids the cost and 
confusion that would likely ensue. Finally, having the same Independent 
Trustees serve on all Fund Boards enhances the ability of each Fund to 
obtain, at modest cost to each separate Fund, the services of Independent 
Trustees, and a Chairman of their Committees, of the caliber, experience and 
business acumen of the individuals who serve as Independent Trustees of the 
Dean Witter Funds. 

COMPENSATION OF INDEPENDENT TRUSTEES 

   The Fund pays each Independent Trustee an annual fee of $1,000 plus a per 
meeting fee of $50 for meetings of the Board of Trustees or committees of the 
Board of Trustees attended by the Trustee (the Fund pays the Chairman of the 
Audit Committee an annual fee of $750 and pays the Chairman of the Committee 
of the Independent Trustees an additional annual fee of $1,200). The Fund 
also reimburses such Trustees for travel and other out-of-pocket expenses 
incurred by them in connection with attending such meetings. Trustees and 
officers of the Fund who are or have been employed by the Investment Manager 
or an affiliated company receive no compensation or expense reimbursement 
from the Fund. 

   The following table illustrates the compensation paid to the Fund's 
Independent Trustees by the Fund for the fiscal year ended September 30, 
1996.

   As of the date of this Statement of Additional Information, 57 of the Dean 
Witter Funds, including the Fund, have adopted a retirement program under 
which an Independent Trustee who retires after serving for at least five 
years (or such lesser period as may be determined by the Board) as an 
Independent Director or Trustee of any Dean Witter Fund that has adopted the 
retirement program (each such Fund referred to as an "Adopting Fund" and each 
such Trustee referred to as an "Eligible Trustee") is entitled to retirement 
payments upon reaching the eligible retirement age (normally, after attaining 
age 72). Annual payments are based upon length of service. Currently, upon 
retirement, each Eligible Trustee is entitled to receive from the Adopting 
Fund, commencing as of his or her retirement date and continuing for the 
remainder of his or her life, an annual retirement benefit (the "Regular 
Benefit") equal to 25.0% of his or her Eligible Compensation plus 0.4166666% 
of such Eligible Compensation for each full month of service as an 
Independent Director or Trustee of any Adopting Fund in excess of five years 
up to a maximum of 50.0% after ten years of service. The foregoing 
percentages may be changed by the Board.(1) "Eligible Compensation" is 
one-fifth of the total compensation earned by such Eligible Trustee for 
service to the Adopting Fund in the five year period prior to the date of the 
Eligible Trustee's retirement. Benefits under the retirement program are not 
secured or funded by the Adopting Funds. 

- ------------ 
(1)    An Eligible Trustee may elect alternate payments of his or her 
       retirement benefits based upon the combined life expectancy of such 
       Eligible Trustee and his or her spouse on the date of such Eligible 
       Trustee's retirement. The amount estimated to be payable under this 
       method, through the remainder of the later of the lives of such 
       Eligible Trustee and spouse, will be the actuarial equivalent of the 
       Regular Benefit. In addition, the Eligible Trustee may elect that the 
       surviving spouse's periodic payment of benefits will be equal to either 
       50% or 100% of the previous periodic amount, an election that, 
       respectively, increases or decreases the previous periodic amount so 
       that the resulting payments will be the actuarial equivalent of the 
       Regular Benefit.

(2)    Based on current levels of compensation. Amount of annual benefits also 
       varies depending on the Trustee's elections described in Footnote (1) 
       above. 
    
   As of the date of this Statement of Additional Information, the aggregate 
number of shares of beneficial interest of the Fund owned by the Fund's 
officers and Trustees as a group was less than 1 percent of the Fund's shares 
of beneficial interest outstanding. 

INVESTMENT PRACTICES AND POLICIES 
- ----------------------------------------------------------------------------- 

   Leveraging. As discussed in the Prospectus, 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), in an effort to enhance 
capital appreciation by leveraging its investments through purchasing 
securities with the borrowed funds. Such borrowings 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 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. 

   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 Act. 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 restoring the 300% asset coverage, the Fund may have to sell a portion of 
its investments at a time when it may be disadvantageous to do so. 

   The investment policy provides that the Fund may not purchase or sell a 
security on margin. The margin and bank borrowing restrictions will prevent 
the ordinary purchase of a security which involves a cash borrowing from a 
broker of any part of the purchase price of a security. 

                               12           
<PAGE>
   In addition to borrowings for leverage, the Fund may also borrow from 
banks an additional amount as a temporary measure for extraordinary or 
emergency purposes, and for these purposes, in no event an amount greater 
than 5% of the value of the Fund's total assets. The Fund did not borrow any 
money during its fiscal year ended September 30, 1996. 

   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, and are at all times secured by cash or cash 
equivalents, which are maintained in a segregated account pursuant to 
applicable regulations and that are at least equal to the market value, 
determined daily, of the loaned securities. The advantage of such loans is 
that the Fund continues to receive the income on the loaned securities while 
at the same time earning interest on the cash amounts deposited as 
collateral, which will be invested in short-term obligations. The Fund will 
not lend its portfolio securities if such loans are not permitted by the laws 
or regulations of any state in which its shares are qualified for sale and 
will not lend more than 25% of the value of its total assets. 

   A loan may be terminated by the borrower on one business day's notice, or 
by the Fund on four business days' notice. If the borrower fails to deliver 
the loaned securities within four days after receipt of notice, the Fund 
could use the collateral to replace the securities while holding the borrower 
liable for any excess of replacement cost over the value of the collateral. 
As with any extensions of credit, there are risks of delay in recovery and in 
some cases even loss of rights in the collateral should the borrower of the 
securities fail financially. However, these loans of portfolio securities 
will only be made to firms deemed by the Fund's management to be creditworthy 
and when the income which can be earned from such loans justifies the 
attendant risks. Upon termination of the loan, the borrower is required to 
return the securities to the Fund. Any gain or loss in the value of the 
securities during the period would inure to the Fund. The creditworthiness of 
firms to which the Fund lends its portfolio securities will be monitored on 
an ongoing basis by the Investment Manager pursuant to procedures adopted and 
reviewed, on an ongoing basis, by the Board of Trustees of the Fund. The Fund 
will pay reasonable finder's, administrative and custodial fees in connection 
with a loan of its securities. 

   When voting or consent rights which accompany loaned securities pass to 
the borrower, the Fund will follow the policy of calling the loaned 
securities, to be delivered within one day after notice, to permit the 
exercise of such rights if the matters involved would have a material effect 
on the Fund's investment in such loaned securities. The Fund has not to date 
lent any of its portfolio securities. 

   Repurchase Agreements. As discussed in the Prospectus, when cash may be 
available for only a few days, it may be invested by the Fund in repurchase 
agreements until such time as it may otherwise be invested or used for 
payments of obligations of the Fund. These agreements, which may be viewed as 
a type of secured lending by the Fund, typically involve the acquisition by 
the Fund of debt securities from a selling financial institution such as a 
bank, savings and loan association or broker-dealer. The agreement provides 
that the Fund will sell back to the institution, and that the institution 
will repurchase, the underlying security ("collateral") at a specified price 
and at a fixed time in the future, usually not more than seven days from the 
date of purchase. The collateral will be maintained in a segregated account 
and will be marked to market daily to determine that the value of the 
collateral, as specified in the agreement, does not decrease below the 
purchase price plus accrued interest. If such decrease occurs, additional 
collateral will be requested and, when received, added to the account to 
maintain full collateralization. The Fund will accrue interest from the 
institution until the time when the repurchase is to occur. Although such 
date is deemed by the Fund to be the maturity date of a repurchase agreement, 
the maturities of securities subject to repurchase agreements are not subject 
to any limits. 

   While repurchase agreements involve certain risks not associated with 
direct investments in debt securities, the Fund follows procedures designed 
to minimize such risks. These procedures include effecting repurchase 
transactions only with large, well-capitalized and well-established financial 
institutions whose financial condition will be continually monitored by the 
Investment Manager subject to procedures established by the Board of Trustees 
of the Fund. In addition, as described above, the value of the collateral 
underlying the repurchase agreement will always 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 

                               13           
<PAGE>
repurchase price, the Fund could suffer a loss. It is the current policy of 
the Fund not to invest in repurchase agreements that do not mature within 
seven days if any such investment, together with any other illiquid assets 
held by the Fund, amounts to more than 15% of its total assets. The Fund's 
investments in repurchase agreements may at times be substantial when, in the 
view of the Investment Manager, liquidity, tax or other considerations 
warrant. 

   Warrants. The Fund may invest in warrants, which are, in effect, an option 
to purchase equity securities at a specific price, generally valid for a 
specific period of time, and have no voting rights, pay no dividends and have 
no rights with respect to the corporation issuing them. If warrants remain 
unexercised at the end of the exercise period, they will lapse and the Fund's 
investment in them will be lost. The prices of warrants do not necessarily 
move parallel to the prices of the underlying securities. 

   When-Issued and Delayed Delivery Securities and Forward Commitments. As 
discussed in the Prospectus, from time to time the Fund may purchase 
securities on a when-issued or delayed delivery basis or may purchase or sell 
securities on a forward commitment basis. When such transactions are 
negotiated, the price is fixed at the time of the commitment, but delivery 
and payment can take place a month or more after the date of the commitment. 
While the Fund will only purchase securities on a when-issued, delayed 
delivery or forward commitment basis with the intention of acquiring the 
securities, the Fund may sell the securities before the settlement date, if 
it is deemed advisable. The securities so purchased or sold are subject to 
market fluctuation and no interest or dividends accrue to the purchaser prior 
to the settlement date. At the time the Fund makes the commitment to purchase 
or sell securities on a when-issued, delayed delivery or forward commitment 
basis, it will record the transaction and thereafter reflect the value, each 
day, of such security purchased or, if a sale, the proceeds to be received, 
in determining its net asset value. At the time of delivery of the 
securities, their value may be more or less than the purchase or sale price. 
The Fund will also establish a segregated account with its custodian bank in 
which it will continually maintain cash or U.S. Government securities or 
other liquid portfolio securities equal in value to commitments to purchase 
securities on a when-issued, delayed delivery or forward commitment basis. It 
is anticipated that the aggregate amount of the Fund's commitments to 
purchase securities on a when-issued, delayed delivery or forward commitment 
basis will not exceed 5% of the Fund's total assets. 

   When, As and If Issued Securities. As discussed in the Prospectus, the 
Fund may purchase securities on a "when, as and if issued" basis under which 
the issuance of the security depends upon the occurrence of a subsequent 
event, such as approval of a merger, corporate reorganization, leveraged 
buy-out or debt restructuring. The commitment for the purchase of any such 
security will not be recognized in the portfolio of the Fund until the 
Investment Manager determines that issuance of the security is probable. At 
such time, the Fund will record the transaction and, in determining its net 
asset value, will reflect the value of the security daily. At such time, the 
Fund will also establish a segregated account with its custodian bank in 
which it will maintain cash or U.S. Government securities or other liquid 
portfolio securities equal in value to recognized commitments for such 
securities. Once a segregated account has been established, if the 
anticipated event does not occur and the securities are not issued the Fund 
will have lost an investment opportunity. It is anticipated that the 
aggregate amount of the Fund's commitments to purchase securities on a "when, 
as and if issued" basis at any one time will not exceed 5% of the Fund's 
total assets. An increase in the percentage of the Fund's assets committed to 
the purchase of securities on a "when, as and if issued" basis may increase 
the volatility of its net asset value. The Investment Manager and the 
Trustees do not believe that the net asset value of the Fund will be 
adversely affected by its purchase of securities on such basis. In addition, 
the value of the Fund's commitments to purchase the securities of any one 
issuer, together with the value of all securities of such issuer owned by the 
Fund, may not exceed 5% of the value of the Fund's total assets at the time 
the initial commitment to purchase such securities is made (see "Investment 
Restrictions"). The Fund may also sell securities on a "when, as and if 
issued" basis provided that the issuance of the security will result 
automatically from the exchange or conversion of a security owned by the Fund 
at the time of the sale. 

   Portfolio Trading. It is anticipated that the Fund's portfolio turnover 
rate will not exceed 300% in any one year. A 300% turnover rate would occur, 
for example, if 300% of the securities held in the Fund's portfolio 
(excluding all securities whose maturities at acquisition were one year or 
less) were sold and replaced within one year.

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

   In addition to the investment restrictions enumerated in the Prospectus, 
the investment restrictions listed below have been adopted by the Fund as 
fundamental policies, except as otherwise indicated. Under the Act, a 
fundamental policy may not be changed without the vote of a majority of the 
outstanding voting securities of the Fund, as defined in the Act. Such a 
majority is defined as the lesser of (a) 67% or more of the shares present at 
a meeting of shareholders of the Fund, if the holders of more than 50% of the 
outstanding shares are present or represented by proxy, or (b) more than 50% 
of the outstanding shares of the Fund. 

   The Fund may not: 

    1. Invest in securities of any issuer if, to the knowledge of the Fund, 
   any officer or trustee of the Fund or any officer or director of the 
   Investment Manager owns more than 1/2 of 1% of the outstanding securities 
   of such issuer, and such officers, trustees and directors who own more 
   than 1/2 of 1% own in the aggregate more than 5% of the outstanding 
   securities of such issuer. 

    2. Purchase or sell real estate or interests therein, although the Fund 
   may purchase securities of issuers which engage in real estate operations 
   and securities which are secured by real estate or interests therein. 

     3. Purchase or sell commodities or commodity futures contracts. 

     4. Purchase oil, gas or other mineral leases, rights or royalty 
    contracts, or exploration or development programs, except that the Fund 
    may invest in the securities of companies which operate, invest in, or 
    sponsor such programs. 

     5. Write, purchase or sell puts, calls, or combinations thereof. 

     6. Purchase securities of other investment companies, except in 
    connection with a merger, consolidation, reorganization or acquisition of 
    assets. 

     7. Invest more than 5% of its total assets in warrants, including not 
    more than 2% of such assets in warrants not listed on either the New York 
    or American Stock Exchange. However, the acquisition of warrants attached 
    to other securities is not subject to this restriction. 

     8. Pledge its assets or assign or otherwise encumber them except to 
    secure borrowings effected within the limitations set forth in restriction 
    (5) in the Prospectus. To meet the requirements of regulations in certain 
    states, the Fund, as a matter of operating policy but not as a fundamental 
    policy, will limit any pledge of its assets to 5% of its net assets so 
    long as shares of the Fund are being sold in those states. 

     9. Issue senior securities as defined in the Act except insofar as the 
    Fund may be deemed to have issued a senior security by reason of: (a) 
    entering into any repurchase agreement; (b) borrowing money in accordance 
    with restrictions described above and in the Prospectus; or (c) lending 
    portfolio securities. 

     10. Make loans of money or securities, except: (a) by the purchase of 
    debt obligations in which the Fund may invest consistent with its 
    investment objective and policies; (b) by investment in repurchase 
    agreements; or (c) by lending its portfolio securities. 

     11. Make short sales of securities. 

     12. Purchase securities on margin, except for such short-term loans as 
    are necessary for the clearance of purchases of portfolio securities. 

     13. Engage in the underwriting of securities, except insofar as the Fund 
    may be deemed an underwriter under the Securities Act of 1933 in disposing 
    of a portfolio security. 

     14. Invest for the purpose of exercising control or management of any 
    other issuer. 

   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. 

                               15           
<PAGE>
   
   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. 
    

PORTFOLIO TRANSACTIONS AND BROKERAGE 
- ----------------------------------------------------------------------------- 

   Subject to the general supervision of the Board of Trustees, the 
Investment Manager is responsible for decisions to buy and sell securities 
for the Fund, the selection of brokers and dealers to effect the 
transactions, and the negotiation of brokerage commissions, if any. Purchases 
and sales of securities on a stock exchange are effected through brokers who 
charge a commission for their services. In the over-the-counter market, 
securities are generally traded on a "net" basis with dealers acting as 
principal for their own accounts without a stated commission, although the 
price of the security usually includes a profit to the dealer. The Fund also 
expects that securities will be purchased at times in underwritten offerings 
where the price includes a fixed amount of compensation, generally referred 
to as the underwriter's concession or discount. On occasion, the Fund may 
also purchase certain money market instruments directly from an issuer, in 
which case no commissions or discounts are paid. During the fiscal years 
ended September 30, 1994, 1995 and 1996, the Fund paid a total of $938,464, 
$662,758 and $1,361,260, respectively, in brokerage commissions. 

   
   The Investment Manager currently serves as investment manager to a number 
of clients, including other investment companies, and may in the future act 
as investment manager or adviser to others. It is the practice of the 
Investment Manager to cause purchase and sale transactions to be allocated 
among the Fund and others whose assets it manages in such manner as it deems 
equitable. In making such allocations among the Fund and other client 
accounts, various factors are considered, including the respective investment 
objectives, the relative size of portfolio holdings of the same or comparable 
securities, the availability of cash for investment, the size of investment 
commitments generally held and the opinions of the persons responsible for 
managing the portfolios of the Fund and other client accounts. In the case of 
certain initial and secondary public offerings, the Investment Manager may 
utilize a pro rata allocation process based on the size of the Dean Witter 
Funds involved and the number of shares available from the public offering. 
    

   The policy of the Fund regarding purchases and sales of securities for its 
portfolio is that primary consideration will be given to obtaining the most 
favorable prices and efficient execution of transactions. Consistent with 
this policy, when securities transactions are effected on a stock exchange, 
the Fund's policy is to pay commissions which are considered fair and 
reasonable without necessarily determining that the lowest possible 
commissions are paid in all circumstances. The Fund believes that a 
requirement always to seek the lowest commission cost could impede effective 
portfolio management and preclude the Fund and the Investment Manager from 
obtaining a high quality of brokerage and research services. In seeking to 
determine the reasonableness of brokerage commissions paid in any 
transaction, the Investment Manager relies upon its experience and knowledge 
regarding commissions generally charged by various brokers and on its 
judgment in evaluating the brokerage and research services received from the 
broker effecting the transaction. Such determinations are necessarily 
subjective and imprecise, as in most cases an exact dollar value for those 
services is not ascertainable. 

   In seeking to implement the Fund's policies, the Investment Manager 
effects transactions with those brokers and dealers who the Investment 
Manager believes provide the most favorable prices and are capable of 
providing efficient executions. If the Investment Manager believes such price 
and execution are obtainable from more than one broker or dealer, it may give 
consideration to placing portfolio transactions with those brokers and 
dealers who also furnish research and other services to the Fund or the 
Investment Manager. Such services may include, but are not limited to, any 
one or more of the following: information as to the availability of 
securities for purchase or sale; statistical or factual information or 
opinions pertaining to investment; wire services; and appraisals or 
evaluations of portfolio securities. During the fiscal year ended September 
30, 1996, the Fund directed the payment of $1,041,291 in brokerage 
commissions in connection with transactions in the aggregate amount of 
$469,988,319 to brokers because of research services provided. 

                               16           
<PAGE>
   The information and services received by the Investment Manager from 
brokers and dealers may be of benefit to the Investment Manager in the 
management of accounts of some of its other clients and may not in all cases 
benefit the Fund directly. While the receipt of such information and services 
is useful in varying degrees and would generally reduce the amount of 
research or services otherwise performed by the Investment Manager and thus 
reduce its expenses, it is of indeterminable value and the management fee 
paid to the Investment Manager is not reduced by any amount that may be 
attributable to the value of such services. 

   Pursuant to an order of the Securities and Exchange Commission, the Fund 
may effect principal transactions in certain money market instruments with 
DWR. The Fund will limit its transactions with DWR to U.S. Government and 
Government Agency Securities, Bank Money Instruments (i.e., Certificates of 
Deposit and Bankers' Acceptances) and Commercial Paper. Such transactions 
will be effected with DWR only when the price available from DWR is better 
than that available from other dealers. During the fiscal years ended 
September 30, 1994, 1995 and 1996, the Fund did not effect any principal 
transactions with DWR. 

   
   Consistent with the policy described above, brokerage transactions in 
securities listed on exchanges or admitted to unlisted trading privileges may 
be effected through DWR and other affiliated brokers and dealers. In order 
for an affiliated broker or dealer to effect any portfolio transactions for 
the Fund, the commissions, fees or other remuneration received by the 
affiliated broker or dealer must be reasonable and fair compared to the 
commissions, fees or other remuneration paid to other brokers in connection 
with comparable transactions involving similar securities being purchased or 
sold on an exchange during a comparable period of time. This standard would 
allow the affiliated broker or dealer to receive no more than the 
remuneration which would be expected to be received by an unaffiliated broker 
in a commensurate arm's-length transaction. Furthermore, the Trustees of the 
Fund, including a majority of the Trustees who are not interested persons of 
the Fund, as defined in the Act, have adopted procedures which are reasonably 
designed to provide that any commissions, fees or other remuneration paid to 
an affiliated broker or dealer are consistent with the foregoing standard. 
The Fund does not reduce the management fee it pays to the Investment Manager 
by any amount of the brokerage commissions it may pay to an affiliated broker 
or dealer. During the fiscal years ended September 30, 1994, 1995 and 1996, 
the Fund paid a total of $118,670, $91,840 and $133,555, respectively, in 
brokerage commissions to DWR. For the fiscal year ended September 30, 1996, 
the brokerage commissions paid to DWR represented approximately 9.81% of the 
total brokerage commissions paid by the Fund for the year and were paid on 
account of transactions having an aggregate dollar value equal to 
approximately 11.26% of the aggregate dollar value of all portfolio 
transactions of the Fund during the year for which commissions were paid. 
    

   During the fiscal year ended September 30, 1996, the Fund did not acquire 
any securities of the ten brokers who executed the largest dollar amounts of 
the Fund's portfolio transactions or of the ten dealers who executed the 
largest dollar amounts of principal transactions with the Fund during the 
period, or securities of the parents of those broker-dealers. 

THE DISTRIBUTOR 
- ----------------------------------------------------------------------------- 

   
   As discussed in the Prospectus, shares of the Fund are distributed by Dean 
Witter Distributors Inc. (the "Distributor"). The Distributor has entered 
into a selected dealer agreement with DWR, which through its own sales 
organization sells shares of the Fund. In addition, the Distributor may enter 
into selected dealer agreements with other selected broker-dealers. The 
Distributor, a Delaware corporation, is a wholly-owned subsidiary of MSDWD. 
The Trustees of the Fund, including a majority of the Trustees who are not, 
and were not at the time they voted, interested persons of the Fund, as 
defined in the Act (the "Independent Trustees"), approved, at their meeting 
held on June 30, 1997, the current Distribution Agreement appointing the 
Distributor as exclusive distributor of the Fund's shares and providing for 
the Distributor to bear distribution expenses not borne by the Fund. By its 
terms, the Distribution Agreement has an initial term ending April 30, 1998 
and will remain in effect from year to year thereafter if approved by the 
Board. 
    

   The Distributor bears all expenses it may incur in providing services 
under the Distribution Agreement. Such expenses include the payment of 
commissions for sales of the Fund's shares and incentive compensation to 
account executives. The Distributor also pays certain expenses in connection 

                               17           
<PAGE>
   
with the distribution of the Fund's shares, including the costs of preparing, 
printing and distributing advertising or promotional materials, and the costs 
of printing and distributing prospectuses and supplements thereto used in 
connection with the offering and sale of the Fund's shares. The Fund bears 
the costs of initial typesetting, printing and distribution of prospectuses 
and supplements thereto to shareholders. The Fund also bears the costs of 
registering the Fund and its shares under federal securities laws and pays 
filing fees in accordance with state securities laws. The Fund and the 
Distributor have agreed to indemnify each other against certain liabilities, 
including liabilities under the Securities Act of 1933, as amended. Under the 
Distribution Agreement, the Distributor uses its best efforts in rendering 
services to the Fund, but in the absence of willful misfeasance, bad faith, 
gross negligence or reckless disregard of its obligations, the Distributor is 
not liable to the Fund or any of its shareholders for any error of judgment 
or mistake of law or for any act or omission or for losses sustained by the 
Fund or its shareholders. 
    

PLAN OF DISTRIBUTION 

   
   The Fund has adopted a Plan of Distribution pursuant to Rule 12b-1 under 
the Act (the "Plan") pursuant to which each Class, other than Class D, pays 
the Distributor compensation accrued daily and payable monthly at the 
following annual rates: 0.25% and 1.0% of the average daily net assets of 
Class A and Class C, respectively, and, with respect to Class B, 1.0% of the 
lesser of: (a) the average daily aggregate gross sales of the Fund's Class B 
shares since the inception of the Fund (not including reinvestments of 
dividends or capital gains distributions), less the average daily aggregate 
net asset value of the Fund's Class B shares redeemed since the Fund's 
inception upon which a contingent deferred sales charge has been imposed or 
upon which such charge has been waived, or (b) the average daily net assets 
of Class B. The Distributor also receives the proceeds of front-end sales 
charges and of contingent deferred sales charges imposed on certain 
redemptions of shares, which are separate and apart from payments made 
pursuant to the Plan (see "Purchase of Fund Shares" in the Prospectus). The 
Distributor has informed the Fund that it and/or DWR received approximately 
$450,000, $991,000 and $810,000 in contingent deferred sales charges for the 
fiscal years ended September 30, 1994, 1995 and 1996, respectively. 

   The Distributor has informed the Fund that the entire fee payable by Class 
A and a portion of the fees payable by each of Class B and Class C each year 
pursuant to the Plan equal to 0.25% of such Class's average daily net assets 
are currently each characterized as a "service fee" under the Rules of the 
Association of the National Association of Securities Dealers, Inc. (of which 
the Distributor is a member). The "service fee" is a payment made for 
personal service and/or the maintenance of shareholder accounts. The 
remaining portion of the Plan fees payable by a Class, if any, is 
characterized as an "asset-based sales charge" as such is defined by the 
aforementioned Rules of the Association. 
    

   The Plan was adopted by a majority vote of the Board of Trustees, 
including all of the Trustees of the Fund who are not "interested persons" of 
the Fund (as defined in the Act) and who have no direct or indirect financial 
interest in the operation of the Plan (the "Independent 12b-1 Trustees"), 
cast in person at a meeting called for the purpose of voting on the Plan, on 
January 18, 1983, by DWR as the then sole shareholder of the Fund on March 1, 
1983 and by the shareholders holding a majority, as defined in the Act, of 
the outstanding voting securities of the Fund at a Special Meeting of 
Shareholders of the Fund held on July 16, 1984. 

   
   At their meeting held on October 30, 1992, the Trustees of the Fund, 
including all of the Independent 12b-1 Trustees, approved certain amendments 
to the Plan which took effect in January, 1993 and were designed to reflect 
the fact that upon an internal reorganization the share distribution 
activities theretofore performed for the Fund by DWR were assumed by the 
Distributor and DWR's sales activities are now being performed pursuant to 
the terms of a selected dealer agreement between the Distributor and DWR. The 
amendments provide that payments under the Plan will be made to the 
Distributor rather than to DWR as before the amendment, and that the 
Distributor in turn is authorized to make payments to DWR, its affiliates or 
other selected broker-dealers (or direct that the Fund pay such entities 
directly). The Distributor is also authorized to retain part of such fee as 
compensation for its own distribution-related expenses. At their meeting held 
on April 28, 1993, the Trustees, including a majority of the 
    

                               18           
<PAGE>
   
Independent 12b-1 Trustees, approved certain technical amendments to the Plan 
in connection with amendments adopted by the National Association of Securities
Dealers, Inc. to its Rules of the Association. At their meeting held on 
October 26, 1995, the Trustees of the Fund, including all of the Independent 
12b-1 Trustees, approved an amendment to the Plan to permit payments to be made
under the Plan with respect to certain distribution expenses incurred in 
connection with the distribution of shares, including personal services to 
shareholders with respect to holdings of such shares, of an investment company 
whose assets are acquired by the Fund in a tax-free reorganization. At their 
meeting held on June 30, 1997, the Trustees, including a majority of the 
Independent 12b-1 Trustees, approved amendments to the Plan to reflect the 
multiple-class structure for the Fund, which took effect on July 28, 1997. 

   Under the Plan and as required by Rule 12b-1, the Trustees receive and 
review promptly after the end of each calendar quarter a written report 
provided by the Distributor of the amounts expended under the Plan and the 
purpose for which such expenditures were made. The Fund accrued amounts 
payable to the Distributor under the Plan, during the fiscal year ended 
September 30, 1996, of $6,461,408. This amount is equal to 1.0% of the Fund's 
average daily net assets for the fiscal year and was calculated pursuant to 
clause (b) of the compensation formula under the Plan. This amount is treated 
by the Fund as an expense in the year it is accrued. This amount represents 
amounts paid by Class B only; there were no Class A or Class C shares 
outstanding on such date. 

   The Plan was adopted in order to permit the implementation of the Fund's 
method of distribution. Under this distribution method the Fund offers four 
Classes of shares, each with a different distribution arrangement as set 
forth in the Prospectus. 

   With respect to Class A shares, DWR compensates its account executives by 
paying them, from proceeds of the front-end sales charge, commissions for the 
sale of Class A shares, currently a gross sales credit of up to 5.0% of the 
amount sold (except as provided in the following sentence) and an annual 
residual commission, currently a residual of up to 0.25% of the current value 
of the respective accounts for which they are the account executives or 
dealers of record in all cases. On orders of $1 million or more (for which no 
sales charge was paid) or net asset value purchases by 401(k) plans or other 
employer-sponsored plans qualified under Section 401(a) of the Internal 
Revenue Code for which Dean Witter Trust Company ("DWTC") or Dean Witter 
Trust FSB ("DWTFSB") serves as Trustee or the 401(k) Support Services Group 
of DWR serves as recordkeeper, the Investment Manager compensates DWR's 
account executives by paying them, from its own funds, a gross sales credit 
of 1.0% of the amount sold. 

   With respect to Class B shares, DWR compensates its account executives by 
paying them, from its own funds, commissions for the sale of Class B shares, 
currently a gross sales credit of up to 5.0% of the amount sold (except as 
provided in the following sentence) and an annual residual commission, 
currently a residual of up to 0.25% of the current value (not including 
reinvested dividends or distributions) of the amount sold in all cases. In 
the case of retirement plans qualified under Section 401(k) of the Internal 
Revenue Code and other employer-sponsored plans qualified under Section 
401(a) of the Internal Revenue Code for which DWTC or DWTFSB serves as 
Trustee or the 401(k) Support Services Group of DWR serves as recordkeeper, 
and which plans are opened on or after July 28, 1997, DWR compensates its 
account executives by paying them, from its own funds, a gross sales credit 
of 3.0% of the amount sold. 

   With respect to Class C shares, DWR compensates its account executives by 
paying them, from its own funds, commissions for the sale of Class C shares, 
currently a gross sales credit of up to 1.0% of the amount sold and an annual 
residual commission, currently a residual of up to 1.0% of the current value 
of the respective accounts for which they are the account executives of 
record. 

   With respect to Class D shares other than shares held by participants in 
the InterCapital mutual fund asset allocation program, the Investment Manager 
compensates DWR's account executives by paying them, from its own funds, 
commissions for the sale of Class D shares, currently a gross sales credit of 
up to 1.0% of the amount sold. There is a chargeback of 100% of the amount 
paid if the Class D shares are redeemed in the first year and a chargeback of 
50% of the amount paid if the Class D shares are 
    

                               19           
<PAGE>
   
redeemed in the second year after purchase. The Investment Manager also 
compensates DWR's account executives by paying them, from its own funds, an 
annual residual commission, currently a residual of up to 0.10% of the current 
value of the respective accounts for which they are the account executives of 
record (not including accounts of participants in the InterCapital mutual fund 
asset allocation program). 

   The gross sales credit is a charge which reflects commissions paid by DWR 
to its account executives and DWR's Fund-associated distribution-related 
expenses, including sales compensation, and overhead and other branch office 
distribution-related expenses including (a) the expenses of operating DWR's 
branch offices in connection with the sale of Fund shares, including lease 
costs, the salaries and employee benefits of operations and sales support 
personnel, utility costs, communications costs and the costs of stationery 
and supplies, (b) the costs of client sales seminars, (c) travel expenses of 
mutual fund sales coordinators to promote the sale of Fund shares and (d) 
other expenses relating to branch promotion of Fund sales. The distribution 
fee that the Distributor receives from the Fund under the Plan, in effect, 
offsets distribution expenses incurred under the Plan on behalf of the Fund 
and, in the case of Class B shares, opportunity costs, such as the gross 
sales credit and an assumed interest charge thereon ("carrying charge"). In 
the Distributor's reporting of the distribution expenses to the Fund, in the 
case of Class B shares, such assumed interest (computed at the "broker's call 
rate") has been calculated on the gross credit as it is reduced by amounts 
received by the Distributor under the Plan and any contingent deferred sales 
charges received by the Distributor upon redemption of shares of the Fund. No 
other interest charge is included as a distribution expense in the 
Distributor's calculation of its distribution costs for this purpose. The 
broker's call rate is the interest rate charged to securities brokers on 
loans secured by exchange-listed securities. 

   The Fund paid 100% of the $6,461,408 accrued under the Plan for the fiscal 
year ended September 30, 1996 to the Distributor. The Distributor and DWR 
estimate that they have spent, pursuant to the Plan, $66,280,910 on behalf of 
the Fund since the inception of the Plan. It is estimated that this amount 
was spent in approximately the following ways: (i) 6.42% 
($4,258,503)--advertising and promotional expenses; (ii) 0.51% 
($334,858)--printing of prospectuses for distribution to other than current 
shareholders; and (iii) 93.07% ($61,687,549)--other expenses, including the 
gross sales credit and the carrying charge, of which 18.84% ($11,624,343) 
represents carrying charges, 33.58% ($20,716,155) represents commission 
credits to DWR branch offices for payments of commissions to account 
executives and 47.58% ($29,347,051) represents overhead and other branch 
office distribution-related expenses. These amounts represent amounts paid by 
Class B only; there were no Class A or Class C shares outstanding on such 
date. 

   The Fund is authorized to reimburse expenses incurred or to be incurred in 
promoting the distribution of the Fund's Class A and Class C shares and in 
servicing shareholder accounts. Reimbursement will be made through payments 
at the end of each month. The amount of each monthly payment may in no event 
exceed an amount equal to a payment at the annual rate of 0.25%, in the case 
of Class A, and 1.0%, in the case of Class C, of the average net assets of 
the respective Class during the month. No interest or other financing 
charges, if any, incurred on any distribution expenses on behalf of Class A 
and Class C will be reimbursable under the Plan. With respect to Class A, in 
the case of all expenses other than expenses representing the service fee, 
and, with respect to Class C, in the case of all expenses other than expenses 
representing a gross sales credit or a residual to account executives, such 
amounts shall be determined at the beginning of each calendar quarter by the 
Trustees, including, a majority of the Independent 12b-1 Trustees. Expenses 
representing the service fee (for Class A) or a gross sales credit or a 
residual to account executives (for Class C) may be reimbursed without prior 
determination. In the event that the Distributor proposes that monies shall 
be reimbursed for other than such expenses, then in making quarterly 
determinations of the amounts that may be reimbursed by the Fund, the 
Distributor will provide and the Trustees will review a quarterly budget of 
projected distribution expenses to be incurred on behalf of the Fund, 
together with a report explaining the purposes and anticipated benefits of 
incurring such expenses. The Trustees will determine which particular 
expenses, and the portions thereof, that may be borne by the Fund, and in 
making such a determination shall consider the scope of the Distributor's 
commitment to promoting the distribution of the Fund's Class A and Class C 
shares. 
    

                               20           
<PAGE>
   
   At any given time, the expenses of distributing shares of the Fund may be 
more or less than the total of (i) the payments made by the Fund pursuant to 
the Plan and (ii) the proceeds of contingent deferred sales charges paid by 
investors upon redemption of shares. The Distributor has advised the Fund 
that in the case of Class B shares the excess distribution expenses, 
including the carrying charge designed to approximate the opportunity costs 
incurred by DWR which arise from it having advanced monies without having 
received the amount of any sales charges imposed at the time of sale of the 
Fund's Class B shares, totalled $28,270,501 as of September 30, 1996. Because 
there is no requirement under the Plan that the Distributor be reimbursed for 
all distribution expenses with respect to Class B shares or any requirement 
that the Plan be continued from year to year, this excess amount does not 
constitute a liability of the Fund. Although there is no legal obligation for 
the Fund to pay expenses incurred in excess of payments made to the 
Distributor under the Plan and the proceeds of contingent deferred sales 
charges paid by investors upon redemption of shares, if for any reason the 
Plan is terminated, the Trustees will consider at that time the manner in 
which to treat such expenses. Any cumulative expenses incurred, but not yet 
recovered through distribution fees or contingent deferred sales charges, may 
or may not be recovered through future distribution fees or contingent 
deferred sales charges. 

   No interested person of the Fund nor any Trustee of the Fund who is not an 
interested person of the Fund, as defined in the Act, has any direct 
financial interest in the operation of the Plan except to the extent that the 
Distributor, InterCapital, DWR, DWSC or certain of their employees may be 
deemed to have such an interest as a result of benefits derived from the 
successful operation of the Plan or as a result of receiving a portion of the 
amounts expended thereunder by the Fund. 

   Under its terms, the Plan had an initial term ending December 31, 1983 and 
will continue from year to year thereafter, provided such continuance is 
approved annually by a vote of the Trustees in the manner described above. 
Prior to the Board's approval of amendments to the Plan to reflect the 
multiple class structure for the Fund, the most recent continuance of the 
Plan for one year, until April 30, 1998, was approved by the Board of 
Trustees of the Fund, including a majority of the Independent 12b-1 Trustees, 
at a Board meeting held on April 24, 1997. Prior to approving the 
continuation of the Plan, the Trustees requested and received from the 
Distributor and reviewed all the information which they deemed necessary to 
arrive at an informed determination. In making their determination to 
continue the Plan, the Trustees considered: (1) the Fund's experience under 
the Plan and whether such experience indicates that the Plan is operating as 
anticipated; (2) the benefits the Fund had obtained, was obtaining and would 
be likely to obtain under the Plan; and (3) what services had been provided 
and were continuing to be provided under the Plan to the Fund and its 
shareholders. Based upon their review, the Trustees of the Fund, including 
each of the Independent 12b-1 Trustees, determined that continuation of the 
Plan would be in the best interest of the Fund and would have a reasonable 
likelihood of continuing to benefit the Fund and its shareholders. In the 
Trustees' quarterly review of the Plan, they will consider its continued 
appropriateness and the level of compensation provided therein. 

   The Plan may not be amended to increase materially the amount to be spent 
for the services described therein without approval by the shareholders of 
the affected Class or Classes of the Fund, and all material amendments to the 
Plan must also be approved by the Trustees in the manner described above. The 
Plan may be terminated at any time, without payment of any penalty, by vote 
of a majority of the Independent 12b-1 Trustees or by a vote of a majority of 
the outstanding voting securities of the Fund (as defined in the Act) on not 
more than thirty days' written notice to any other party to the Plan. So long 
as the Plan is in effect, the election and nomination of Independent 12b-1 
Trustees shall be committed to the discretion of the Independent 12b-1 
Trustees. 
    

DETERMINATION OF NET ASSET VALUE 
- ----------------------------------------------------------------------------- 

   As stated in the Prospectus, short-term securities with remaining 
maturities of sixty days or less at the time of purchase are valued at 
amortized cost, unless the Trustees determine such does not reflect the 
securities' market value, in which case these securities will be valued at 
their fair value as determined by the Trustees. Other short-term debt 
securities will be valued on a mark-to-market basis until such time as they 
reach a remaining maturity of sixty days, whereupon they will be valued at 
amortized cost using their value on the 61st day unless the Trustees 
determine such does not reflect the securities' market 

                               21           
<PAGE>
value, in which case these securities will be valued at their fair value as 
determined by the Trustees. All other securities and other assets are valued 
at their fair value as determined in good faith under procedures established 
by and under the supervision of the Trustees. 

   
   The net asset value per share for each Class of shares of the Fund is 
determined once daily as of 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. The New York Stock 
Exchange currently observes the following holidays: New Year's Day; 
Presidents' Day; Good Friday; Memorial Day; Independence Day; Labor Day; 
Thanksgiving Day; and Christmas Day. 

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

   As discussed in the Prospectus, the Fund offers four Classes of shares as 
follows: 

INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES 

   Class A shares are sold to investors with an initial sales charge that 
declines to zero for larger purchases; however, Class A shares sold without 
an initial sales charge are subject to a contingent deferred sales charge 
("CDSC") of 1.0% if redeemed within one year of purchase, except in the 
circumstances discussed in the Prospectus. 

   Right of Accumulation. As discussed in the Prospectus, investors may 
combine the current value of shares purchased in separate transactions for 
purposes of benefiting from the reduced sales charges available for purchases 
of shares of the Fund totalling at least $25,000 in net asset value. For 
example, if any person or entity who qualifies for this privilege holds Class 
A shares of the Fund and/or other Dean Witter Funds that are multiple class 
funds ("Dean Witter Multi-Class Funds") or shares of other Dean Witter Funds 
sold with a front-end sales charge purchased at a price including a front-end 
sales charge having a current value of $5,000, and purchases $20,000 of 
additional shares of the Fund, the sales charge applicable to the $20,000 
purchase would be 4.75% of the offering price. 

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

   Letter of Intent. As discussed in the Prospectus, reduced sales charges 
are available to investors who enter into a written Letter of Intent 
providing for the purchase, within a thirteen-month period, of Class A shares 
of the Fund from the Distributor or from a single Selected Broker-Dealer. 

   A Letter of Intent permits an investor to establish a total investment 
goal to be achieved by any number of purchases over a thirteen-month period. 
Each purchase of Class A shares made during the period will receive the 
reduced sales commission applicable to the amount represented by the goal, as 
if it were a single purchase. A number of shares equal in value to 5% of the 
dollar amount of the Letter of Intent will be held in escrow by the Transfer 
Agent, in the name of the shareholder. The initial purchase under a Letter of 
Intent must be equal to at least 5% of the stated investment goal. 

   The Letter of Intent does not obligate the investor to purchase, nor the 
Fund to sell, the indicated amount. In the event the Letter of Intent goal is 
not achieved within the thirteen-month period, the investor is required to 
pay the difference between the sales charge otherwise applicable to the 
purchases made during this period and sales charges actually paid. Such 
payment may be made directly to the Distributor or, if not paid, the 
Distributor is authorized by the shareholder to liquidate a sufficient number 
of his or her escrowed shares to obtain such difference. 

   If the goal is exceeded and purchases pass the next sales charge level, 
the sales charge on the entire amount of the purchase that results in passing 
that level and on subsequent purchases will be subject to further reduced 
sales charges in the same manner as set forth above under "Right of 
Accumulation," but there will be no retroactive reduction of sales charges on 
previous purchases. For the 
    

                               22           
<PAGE>
   
purpose of determining whether the investor is entitled to a further reduced 
sales charge applicable to purchases at or above a sales charge level which 
exceeds the stated goal of a Letter of Intent, the cumulative current net 
asset value of any shares owned by the investor in any other Dean Witter 
Funds held by the shareholder which were previously purchased at a price 
including a front-end sales charge (including shares of the Fund and other 
Dean Witter Funds acquired in exchange for those shares, and including in 
each case shares acquired through reinvestment of dividends and 
distributions) will be added to the cost or net asset value of shares of the 
Fund owned by the investor. However, shares of "Exchange Funds" (see 
"Shareholder Services--Exchange Privilege") and the purchase of shares of 
other Dean Witter Funds will not be included in determining whether the 
stated goal of a Letter of Intent has been reached. 

   At any time while a Letter of Intent is in effect, a shareholder may, by 
written notice to the Distributor, increase the amount of the stated goal. In 
that event, only shares purchased during the previous 90-day period and still 
owned by the shareholder will be included in the new sales charge reduction. 
The 5% escrow and minimum purchase requirements will be applicable to the new 
stated goal. Investors electing to purchase shares of the Fund pursuant to a 
Letter of Intent should carefully read such Letter of Intent. 

CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE--CLASS B SHARES 

   Class B shares are sold without an initial sales charge but are subject to 
a CDSC payable upon most redemptions within six years after purchase. As 
stated in the Prospectus, a CDSC will be imposed on any redemption by an 
investor if after such redemption the current value of the investor's Class B 
shares of the Fund is less than the dollar amount of all payments by the 
shareholder for the purchase of Class B shares during the preceding six years 
(or, in the case of shares held by certain employer-sponsored benefit plans, 
three years). However, no CDSC will be imposed to the extent that the net 
asset value of the shares redeemed does not exceed: (a) the current net asset 
value of shares purchased more than six years (or, in the case of shares held 
by certain employer-sponsored benefit plans, three years) prior to the 
redemption, plus (b) the current net asset value of shares purchased through 
reinvestment of dividends or distributions of the Fund or another Dean Witter 
Fund (see "Shareholder Services--Targeted Dividends"), plus (c) the current 
net asset value of shares acquired in exchange for (i) shares of Dean Witter 
front-end sales charge funds, or (ii) shares of other Dean Witter Funds for 
which shares of front-end sales charge funds have been exchanged (see 
"Shareholder Services--Exchange Privilege"), plus (d) increases in the net 
asset value of the investor's shares above the total amount of payments for 
the purchase of Fund shares made during the preceding six (three) years. The 
CDSC will be paid to the Distributor. In 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 determining the applicability of the CDSC to each redemption, the 
amount which represents an increase in the net asset value of the investor's 
shares above the amount of the total payments for the purchase of shares 
within the last six years (or, in the case of shares held by certain 
employer-sponsored benefit plans, three years) will be redeemed first. In the 
event the redemption amount exceeds such increase in value, the next portion 
of the amount redeemed will be the amount which represents the net asset 
value of the investor's shares purchased more than six (three) years prior to 
the redemption and/or shares purchased through reinvestment of dividends or 
distributions and/or shares acquired in exchange for shares of Dean Witter 
front-end sales charge funds, or for shares of other Dean Witter funds for 
which shares of front-end sales charge funds have been exchanged. A portion 
of the amount redeemed which exceeds an amount which represents both such 
increase in value and the value of shares purchased more than six years (or, 
in the case of shares held by certain employer-sponsored benefit plans, three 
years) prior to the redemption and/or shares purchased through reinvestment 
of dividends or distributions and/or shares acquired in the above-described 
exchanges will be subject to a CDSC. 

   The amount of the CDSC, if any, will vary depending on the number of years 
from the time of payment for the purchase of Class B shares of the Fund until 
the time of redemption of such shares. For purposes of determining the number 
of years from the time of any payment for the purchase of shares, all 
payments made during a month will be aggregated and deemed to have been made 
on the last day 
    

                               23

of the month. The following table sets forth the rates of the CDSC applicable 
to most Class B shares of the Fund:

as recordkeeper and whose accounts are opened on or after July 28, 1997:

   In determining the rate of the CDSC, it will be assumed that a redemption 
is made of shares held by the investor for the longest period of time within 
the applicable six-year or three-year period. This will result in any such 
CDSC being imposed at the lowest possible rate. The CDSC will be imposed, in 
accordance with the table shown above, on any redemptions within six years 
(or, in the case of shares held by certain employer-sponsored benefit plans, 
three years) of purchase which are in excess of these amounts and which 
redemptions do not qualify for waiver of the CDSC, as described in the 
Prospectus. 

LEVEL LOAD ALTERNATIVE--CLASS C SHARES 

   Class C shares are sold without a sales charge but are subject to a CDSC 
of 1.0% on most redemptions made within one year after purchase, except in 
the circumstances discussed in the Prospectus. 

NO LOAD ALTERNATIVE--CLASS D SHARES 

   Class D shares are offered without any sales charge on purchase or 
redemption. Class D shares are offered only to those persons meeting the 
qualifications set forth in the Prospectus. 
    

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

   
   Upon the purchase of shares of the Fund, a Shareholder Investment Account 
is opened for the investor on the books of the Fund and maintained by the 
Transfer Agent. This is an open account in which shares owned by the investor 
are credited by the Transfer Agent in lieu of issuance of a share 
certificate. If a share certificate is desired, it must be requested in 
writing for each transaction. Certificates are issued only for full shares 
and may be redeposited in the account at any time. There is no charge to the 
investor for issuance of a certificate. Whenever a shareholder instituted 
transaction takes place in the Shareholder Investment Account, the 
shareholder will be mailed a confirmation of the transaction from the Fund or 
from DWR or other selected broker-dealer. 

   Automatic Investment of Dividends and Distributions. As stated in the 
Prospectus, all income dividends and capital gains distributions are 
automatically paid in full and fractional shares of the applicable Class of 
the Fund, unless the shareholder requests that they be paid in cash. Each 
purchase of shares of the Fund is made upon the condition that the Transfer 
Agent is thereby automatically 
    

                               24           
<PAGE>
   
appointed as agent of the investor to receive all dividends and capital gains 
distributions on shares owned by the investor. Such dividends and 
distributions will be paid, at the net asset value per share, in shares of 
the applicable Class of the Fund (or in cash if the shareholder so requests) 
as of the close of business on the record date. At any time an investor may 
request the Transfer Agent, in writing, to have subsequent dividends and/or 
capital gains distributions paid to him or her in cash rather than shares. To 
assure sufficient time to process the change, such request should be received 
by the Transfer Agent at least five business days prior to the record date of 
the dividend or distribution. In the case of recently purchased shares for 
which registration instructions have not been received on the record date, 
cash payments will be made to DWR or other selected broker-dealer, and will 
be forwarded to the shareholder, upon the receipt of proper instructions. 

   Targeted Dividends. (Service Mark)  In states where it is legally 
permissible, shareholders may also have all income dividends and capital 
gains distributions automatically invested in shares of any Class of an 
open-end Dean Witter Fund other than Dean Witter Developing Growth Securities 
Trust or in another Class of Dean Witter Developing Growth Securities Trust. 
Such investment will be made as described above for automatic investment in 
shares of the applicable Class of the Fund, at the net asset value per share 
of the selected Dean Witter Fund as of the close of business on the payment 
date of the dividend or distribution and will begin to earn dividends, if 
any, in the selected Dean Witter Fund the next business day. To participate 
in the Targeted Dividends program, shareholders should contact their DWR or 
other selected broker-dealer account executive or the Transfer Agent. 
Shareholders of the Fund must be shareholders of the selected Class of the 
Dean Witter Fund targeted to receive investments from dividends at the time 
they enter the Targeted Dividends program. Investors should review the 
prospectus of the targeted Dean Witter Fund before entering the program. 

   EasyInvest. (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. Shares purchased through EasyInvest will be added to the 
shareholder's existing account at the net asset value calculated the same 
business day the transfer of funds is effected. For further information or to 
subscribe to EasyInvest, shareholders should contact their DWR or other 
selected broker-dealer account executive or the Transfer Agent. 

   Investment of Dividends or Distributions Received in Cash. As discussed in 
the Prospectus, any shareholder who receives a cash payment representing a 
dividend or distribution may invest such dividend or distribution in shares 
of the applicable Class at net asset value, without the imposition of a CDSC 
upon redemption, by returning the check or the proceeds to the Transfer Agent 
within thirty days after the payment date. If the shareholder returns the 
proceeds of a dividend or distribution, such funds must be accompanied by a 
signed statement indicating that the proceeds constitute a dividend or 
distribution to be invested. Such investment will be made at the net asset 
value per share next determined after receipt of the check or the proceeds by 
the Transfer Agent. 

   Systematic Withdrawal Plan. As discussed in the Prospectus, a systematic 
withdrawal plan (the "Withdrawal Plan") is available for shareholders who own 
or purchase shares of the Fund having a minimum value of $10,000 based upon 
the then current net asset value. The Withdrawal Plan provides for monthly or 
quarterly (March, June, September and December) checks in any dollar amount, 
not less than $25, or in any whole percentage of the account balance, on an 
annualized basis. Any applicable contingent deferred sales charge will be 
imposed on shares redeemed under the Withdrawal Plan (see "Purchase of Fund 
Shares"). Therefore, any shareholder participating in the Withdrawal Plan 
will have sufficient shares redeemed from his or her account so that the 
proceeds (net of any applicable CDSC) to the shareholder will be the 
designated monthly or quarterly amount. 
    

   The Transfer Agent acts as agent for the shareholder in tendering to the 
Fund for redemption sufficient full and fractional shares to provide the 
amount of the periodic withdrawal payment designated in the application. The 
shares will be redeemed at their net asset value determined, at the 
shareholder's option, on the tenth or twenty-fifth day (or next following 
business day) of the relevant month or quarter 

                               25           
<PAGE>
and normally a check for the proceeds will be mailed by the Transfer Agent, 
or amounts credited to a shareholder's DWR or other selected broker-dealer 
brokerage account, within five business days after the date of redemption. 
The Withdrawal Plan may be terminated at any time by the Fund. 

   Withdrawal Plan payments should not be considered as dividends, yields or 
income. If periodic withdrawal plan payments continuously exceed net 
investment income and net capital gains, the shareholder's original 
investment will be correspondingly reduced and ultimately exhausted. 

   
   Each withdrawal constitutes a redemption of shares and any gain or loss 
realized must be recognized for federal income tax purposes. Although the 
shareholder may make additional investments of $2,500 or more under the 
Withdrawal Plan, withdrawals made concurrently with purchases of additional 
shares may be inadvisable because of sales charges which may be applicable to 
purchases or redemptions of shares (see "Purchase of Fund Shares"). 
    

   Any shareholder who wishes to have payments under the Withdrawal Plan made 
to a third party or sent to an address other than the one listed on the 
account must send complete written instructions to the Transfer Agent to 
enroll in the Withdrawal Plan. The shareholder's signature on such 
instructions must be guaranteed by an eligible guarantor acceptable to the 
Transfer Agent (shareholders should contact the Transfer Agent for a 
determination as to whether a particular institution is such an eligible 
guarantor). A shareholder may, at any time, change the amount and interval of 
withdrawal payments through his or her account executive or by written 
notification to the Transfer Agent. In addition, the party and/or the address 
to which checks are mailed may be changed by written notification to the 
Transfer Agent, with signature guarantees required in the manner described 
above. The shareholder may also terminate the Withdrawal Plan at any time by 
written notice to the Transfer Agent. In the event of such termination, the 
account will be continued as a regular shareholder investment account. The 
shareholder may also redeem all or part of the shares held in the Withdrawal 
Plan account (see "Redemptions and Repurchases" in the Prospectus) at any 
time. 

   
   Direct Investments through Transfer Agent. As discussed in the Prospectus, 
shareholders may make additional investments in any Class of shares of the 
Fund for which they qualify at any time by sending a check in any amount, not 
less than $100, payable to Dean Witter Developing Growth Securities Trust, 
and indicating the selected Class, directly to the Fund's Transfer Agent. In 
the case of Class A shares, after deduction of any applicable sales charge, 
the balance will be applied to the purchase of Fund shares, and, in the case 
of shares of the other Classes, the entire amount will be applied to the 
purchase of Fund shares, at the net asset value per share next computed after 
receipt of the check or purchase payment by the Transfer Agent. The shares so 
purchased will be credited to the investor's account. 
    

EXCHANGE PRIVILEGE 

   
   As discussed in the Prospectus, the Fund makes available to its 
shareholders an Exchange Privilege whereby shareholders of the Fund may 
exchange their shares for shares of the same Class of shares of any other 
Dean Witter Multi-Class Fund without the imposition of any exchange fee. 
Shares may also be exchanged for shares of any of the following funds: Dean 
Witter Short-Term U.S. Treasury Trust, Dean Witter Limited Term Municipal 
Trust, Dean Witter Short-Term Bond Fund, Dean Witter Intermediate Term U.S. 
Treasury Trust and five Dean Witter Funds which are money market funds (the 
foregoing nine funds are hereinafter referred to as the "Exchange Funds"). 
Class A shares may also be exchanged for shares of Dean Witter Multi-State 
Municipal Series Trust and Dean Witter Hawaii Municipal Trust, which are Dean 
Witter Funds sold with a front-end sales charge ("FSC Funds"). Class B shares 
may also be exchanged for shares of Dean Witter Global Short-Term Income Fund 
Inc., Dean Witter High Income Securities and Dean Witter National Municipal 
Trust, which are Dean Witter Funds offered with a CDSC ("CDSC Funds"). 
Exchanges may be made after the shares of the Fund acquired by purchase (not 
by exchange or dividend reinvestment) have been held for thirty days. There 
is no waiting period for exchanges of shares acquired by exchange or dividend 
reinvestment. An exchange will be treated for federal income tax purposes the 
same as a repurchase or redemption of shares, on which the shareholder may 
realize a capital gain or loss. 
    

                               26           
<PAGE>
   Any new account established through the Exchange Privilege will have the 
same registration and cash dividend or dividend reinvestment plan as the 
present account, unless the Transfer Agent receives written notification to 
the contrary. For telephone exchanges, the exact registration of the existing 
account and the account number must be provided. 

   Any shares held in certificate form cannot be exchanged but must be 
forwarded to the Transfer Agent and deposited into the shareholder's account 
before being eligible for exchange. (Certificates mailed in for deposit 
should not be endorsed.) 

   
   As described below, and in the Prospectus under the caption ''Purchase of 
Fund Shares," a CDSC may be imposed upon a redemption, depending on a number 
of factors, including the number of years from the time of purchase until the 
time of redemption or exchange ("holding period"). When shares of a Dean 
Witter Multi-Class Fund or any CDSC fund are exchanged for shares of an 
Exchange Fund, the exchange is executed at no charge to the shareholder, 
without the imposition of the CDSC at the time of the exchange. During the 
period of time the shareholder remains in the Exchange Fund (calculated from 
the last day of the month in which the Exchange Fund shares were acquired), 
the holding period or "year since purchase payment made" is frozen. When 
shares are redeemed out of the Exchange Fund, they will be subject to a CDSC 
which would be based upon the period of time the shareholder held shares in a 
Dean Witter Multi-Class Fund or in a CDSC Fund. However, in the case of 
shares exchanged into an Exchange Fund on or after April 23, 1990, upon a 
redemption of shares which results in a CDSC being imposed, a credit (not to 
exceed the amount of the CDSC) will be given in an amount equal to the 
Exchange Fund 12b-1 distribution fees incurred on or after that date which 
are attributable to those shares. Shareholders acquiring shares of an 
Exchange Fund pursuant to this exchange privilege may exchange those shares 
back into a Dean Witter Multi-Class Fund or a CDSC Fund from the Exchange 
Fund, with no CDSC being imposed on such exchange. The holding period 
previously frozen when shares were first exchanged for shares of the Exchange 
Fund resumes on the last day of the month in which shares of a Dean Witter 
Multi-Class Fund or of a CDSC Fund are reacquired. A CDSC is imposed only 
upon an ultimate redemption, based upon the time (calculated as described 
above) the shareholder was invested in a Dean Witter Multi-Class Fund or in a 
CDSC Fund. In the case of exchanges of Class A shares which are subject to a 
CDSC, the holding period also includes the time (calculated as described 
above) the shareholder was invested in a FSC Fund. 

   When shares initially purchased in a Dean Witter Multi-Class Fund or in a 
CDSC Fund are exchanged for shares of a Dean Witter Multi-Class Fund, shares 
of a CDSC Fund, shares of a FSC Fund, or shares of an Exchange Fund, the date 
of purchase of the shares of the fund exchanged into, for purposes of the 
CDSC upon redemption, will be the last day of the month in which the shares 
being exchanged were originally purchased. In allocating the purchase 
payments between funds for purposes of the CDSC, the amount which represents 
the current net asset value of shares at the time of the exchange which were 
(i) purchased more than one, three or six years (depending on the CDSC 
schedule applicable to the shares) prior to the exchange, (ii) originally 
acquired through reinvestment of dividends or distributions and (iii) 
acquired in exchange for shares of FSC Funds, or for shares of other Dean 
Witter Funds for which shares of FSC Funds have been exchanged (all such 
shares called "Free Shares"), will be exchanged first. After an exchange, all 
dividends earned on shares in an Exchange Fund will be considered Free 
Shares. If the exchanged amount exceeds the value of such Free Shares, an 
exchange is made, on a block-by-block basis, of non-Free Shares held for the 
longest period of time (except that, with respect to Class B shares, if 
shares held for identical periods of time but subject to different CDSC 
schedules are held in the same Exchange Privilege account, the shares of that 
block that are subject to a lower CDSC rate will be exchanged prior to the 
shares of that block that are subject to a higher CDSC rate). Shares equal to 
any appreciation in the value of non-Free Shares exchanged will be treated as 
Free Shares, and the amount of the purchase payments for the non-Free Shares 
of the fund exchanged into will be equal to the lesser of (a) the purchase 
payments for, or (b) the current net asset value of, the exchanged non-Free 
Shares. If an exchange between funds would result in exchange of only part of 
a particular block of non-Free Shares, then shares equal to any appreciation 
in the value of the block (up to the amount of the exchange) will be treated 
as Free Shares and exchanged first, and the purchase payment for that block 
will be allocated on a pro rata basis between the non-Free Shares of that 
block 
    

                               27           
<PAGE>
   
to be retained and the non-Free Shares to be exchanged. The prorated amount 
of such purchase payment attributable to the retained non-Free Shares will 
remain as the purchase payment for such shares, and the amount of purchase 
payment for the exchanged non-Free Shares will be equal to the lesser of (a) 
the prorated amount of the purchase payment for, or (b) the current net asset 
value of, those exchanged non-Free Shares. Based upon the procedures 
described in the Prospectus under the caption "Purchase of Fund Shares," any 
applicable CDSC will be imposed upon the ultimate redemption of shares of any 
fund, regardless of the number of exchanges since those shares were 
originally purchased. 
    

   With respect to the redemption or repurchase of shares of the Fund, the 
application of proceeds to the purchase of new shares in the Fund or any 
other of the funds and the general administration of the Exchange Privilege, 
the Transfer Agent acts as agent for the Distributor and for the 
shareholder's selected broker-dealer, if any, in the performance of such 
functions. With respect to exchanges, redemptions or repurchases, the 
Transfer Agent shall be liable for its own negligence and not for the default 
or negligence of its correspondents or for losses in transit. The Fund shall 
not be liable for any default or negligence of the Transfer Agent, the 
Distributor or any selected broker-dealer. 

   The Distributor and any selected broker-dealer have authorized and 
appointed the Transfer Agent to act as their agent in connection with the 
application of proceeds of any redemption of Fund shares to the purchase of 
shares of any other fund and the general administration of the Exchange 
Privilege. No commission or discounts will be paid to the Distributor or any 
selected broker-dealer for any transactions pursuant to this Exchange 
Privilege. 

   
   Exchanges are subject to the minimum investment requirement and any other 
conditions imposed by each fund. (The minimum initial investment for the 
Exchange Privilege account of each Class is $5,000 for Dean Witter Liquid 
Asset Fund Inc., Dean Witter Tax-Free Daily Income Trust, Dean Witter 
California Tax-Free Daily Income Trust and Dean Witter New York Municipal 
Money Market Trust, although those funds may, in their discretion, accept 
initial investments of as low as $1,000. The minimum initial investment for 
the Exchange Privilege account of each Class is $10,000 for Dean Witter 
Short-Term U.S. Treasury Trust, although that fund, in its discretion, may 
accept initial purchases of as low as $5,000. The minimum initial investment 
for the Exchange Privilege account of each Class is $5,000 for Dean Witter 
Special Value Fund. The minimum initial investment for the Exchange Privilege 
account of each Class of all other Dean Witter Funds for which the Exchange 
Privilege is available is $1,000.) Upon exchange into an Exchange Fund, the 
shares of that fund will be held in a special Exchange Privilege Account 
separately from accounts of those shareholders who have acquired their shares 
directly from that fund. As a result, certain services normally available to 
shareholders of those funds, including the check writing feature, will not be 
available for funds held in that account. 
    

   The Fund and each of the other Dean Witter Funds may limit the number of 
times this Exchange Privilege may be exercised by any investor within a 
specified period of time. Also, the Exchange Privilege may be terminated or 
revised at any time by the Fund and/or any of the Dean Witter funds for 
which shares of the Fund have been exchanged, upon such notice as may be 
required by applicable regulatory agencies (presently sixty days' prior 
written notice for termination or material revision), provided that six 
months' prior written notice of termination will be given to the shareholders 
who hold shares of Exchange Funds pursuant to the Exchange Privilege, and 
provided further that the Exchange Privilege may be terminated or materially 
revised without notice at times (a) when the New York Stock Exchange is 
closed for other than customary weekends and holidays, (b) when trading on 
that Exchange is restricted, (c) when an emergency exists as a result of 
which disposal by the Fund of securities owned by it is not reasonably 
practicable or it is not reasonably practicable for the Fund fairly to 
determine the value of its net assets, (d) during any other period when the 
Securities and Exchange Commission by order so permits (provided that 
applicable rules and regulations of the Securities and Exchange Commission 
shall govern as to whether the conditions prescribed in (b) or (c) exist) or 
(e) if the Fund would be unable to invest amounts effectively in accordance 
with its investment objective, policies and restrictions. 

   For further information regarding the Exchange Privilege, shareholders 
should contact their DWR or other selected broker-dealer account executive or 
the Transfer Agent.

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

   
   Redemption. As stated in the Prospectus, shares of each Class of the Fund 
can be redeemed for cash at any time at the net asset value per share next 
determined; however, such redemption proceeds will be reduced by the amount 
of any applicable CDSC (see below). If shares are held in a shareholder's 
account without a share certificate, a written request for redemption to the 
Fund's Transfer Agent at P.O. Box 983, Jersey City, NJ 07303 is required. If 
certificates are held by the shareholder, the shares may be redeemed by 
surrendering the certificates with a written request for redemption. The 
share certificate, or an accompanying stock power, and the request for 
redemption, must be signed by the shareholder or shareholders exactly as the 
shares are registered. Each request for redemption, whether or not 
accompanied by a share certificate, must be sent to the Fund's Transfer 
Agent, which will redeem the shares at their net asset value next computed 
(see "Purchase of Fund Shares" in the Prospectus) after it receives the 
request, and certificate, if any, in good order. Any redemption request 
received after such computation will be redeemed at the next determined net 
asset value. The term "good order" means that the share certificate, if any, 
and request for redemption are properly signed, accompanied by any 
documentation required by the Transfer Agent, and bear signature guarantees 
when required by the Fund or the Transfer Agent. If redemption is requested 
by a corporation, partnership, trust or fiduciary, the Transfer Agent may 
require that written evidence of authority acceptable to the Transfer Agent 
be submitted before such request is accepted. 
    

   Whether certificates are held by the shareholder or shares are held in a 
shareholder's account, if the proceeds are to be paid to any person other 
than the record owner, or if the proceeds are to be paid to a corporation 
(other than the Distributor or a selected broker-dealer for the account of 
the shareholder), partnership, trust or fiduciary, or sent to the shareholder 
at an address other than the registered address, signatures must be 
guaranteed by an eligible guarantor acceptable to the Transfer Agent 
(shareholders should contact the Transfer Agent for a determination as to 
whether a particular institution is such an eligible guarantor). A stock 
power may be obtained from any dealer or commercial bank. The Fund may change 
the signature guarantee requirements from time to time upon notice to 
shareholders, which may be by means of a new prospectus. 

   
   Repurchase. As stated in the Prospectus, DWR and other selected 
broker-dealers are authorized to repurchase shares represented by a share 
certificate which is delivered to any of their offices. Shares held in a 
shareholder's account without a share certificate may also be repurchased by 
DWR and other selected broker-dealers upon the telephonic request of the 
shareholder. The repurchase price is the net asset value next computed after 
such purchase order is received by DWR or other selected broker-dealer 
reduced by any applicable CDSC. 

   Payment for Shares Redeemed or Repurchased. As discussed in the 
Prospectus, payment for shares of any Class presented for repurchase or 
redemption will be made by check within seven days after receipt by the 
Transfer Agent of the certificate and/or written request in good order. The 
term good order means that the share certificate, if any, and request for 
redemption are properly signed, accompanied by any documentation required by 
the Transfer Agent, and bear signature guarantees when required by the Fund 
or the Transfer Agent. Such payment may be postponed or the right of 
redemption suspended at times (a) when the New York Stock Exchange is closed 
for other than customary weekends and holidays, (b) when trading on that 
Exchange is restricted, (c) when an emergency exists as a result of which 
disposal by the Fund of securities owned by it is not reasonably practicable 
or it is not reasonably practicable for the Fund fairly to determine the 
value of its net assets, or (d) during any other period when the Securities 
and Exchange Commission by order so permits; provided that applicable rules 
and regulations of the Securities and Exchange Commission shall govern as to 
whether the conditions prescribed in (b) or (c) exist. If the shares to be 
redeemed have recently been purchased by check (including a certificate or 
bank cashier's check), payment of redemption proceeds may be delayed for the 
minimum time needed to verify that the check used for investment has been 
honored (not more than fifteen days from the time of receipt of the check by 
the Transfer Agent). Shareholders maintaining margin accounts with DWR or 
another selected broker-dealer are referred to their account executive 
regarding restrictions on redemption of shares of the Fund pledged in the 
margin account. 
    

                               29           
<PAGE>
   
   Transfers of Shares. In the event a shareholder requests a transfer of any 
shares to a new registration, such shares will be transferred without sales 
charge at the time of transfer. With regard to the status of shares which are 
either subject to the CDSC or free of such charge (and with regard to the 
length of time shares subject to the charge have been held), any transfer 
involving less than all the shares in an account will be made on a pro rata 
basis (that is, by transferring shares in the same proportion that the 
transferred shares bear to the total shares in the account immediately prior 
to the transfer). The transferred shares will continue to be subject to any 
applicable CDSC as if they had not been so transferred. 

   Reinstatement Privilege. As discussed in the Prospectus, a shareholder who 
has had his or her shares redeemed or repurchased and has not previously 
exercised this reinstatement privilege may, within 35 days after the 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 at the 
net asset value next determined after a reinstatement request, together with 
such proceeds, is received by the Transfer Agent. 
    

   Exercise of the reinstatement privilege will not affect the federal income 
tax treatment of any gain or loss realized upon the redemption or repurchase, 
except that if the redemption or repurchase resulted in a loss and 
reinstatement is made in shares of the Fund, some or all of the loss, 
depending on the amount reinstated, will not be allowed as a deduction for 
federal income tax purposes but will be applied to adjust the cost basis of 
the shares acquired upon reinstatement. 

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

   As discussed in the Prospectus, the Fund will determine either to 
distribute or to retain all or part of any net long-term capital gains in any 
year for reinvestment. If any such gains are retained, the Fund will pay 
federal income tax thereon, and will notify shareholders that, following an 
election by the Fund, the shareholders will be required to include such 
undistributed gains in determining their taxable income and may claim their 
share of the tax paid by the Fund as a credit against their individual 
federal income tax. 

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

   Gains or losses on the sales of securities by the Fund will be long-term 
capital gains or losses if the securities have been held by the Fund for more 
than one year. Gains or losses on the sale of securities held for one year or 
less will be short-term capital gains or losses. 

   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 dividends received deduction. 

   Any ordinary income dividends or capital gains distributions received by a 
shareholder from any investment company will have the effect of reducing the 
net asset value of the shareholder's shares in that company by the exact 
amount of the dividend or capital gains distribution. Furthermore, capital 
gains distributions and ordinary income dividends are subject to federal 
income taxes. If the net asset value of the shares should be reduced below a 
shareholder's cost as a result of the payment of dividends or realized 
long-term capital gains, such payment would be in part a return of the 
shareholder's investment to the extent of such reduction below the 
shareholder's cost, but nonetheless would be taxable to the shareholder. 
Therefore, an investor should consider the tax implications of purchasing 
Fund shares immediately prior to a dividend or distribution record date. 

                               30           
<PAGE>
   Dividend payments will be eligible for the federal dividends received 
deduction available to the Fund's corporate shareholders only to the extent 
the aggregate dividends received by the Fund would be eligible for the 
deduction if the Fund were the shareholder claiming the dividends received 
deduction. The amount of dividends paid by the Fund which may qualify for the 
dividends received deduction is limited to the aggregate amount of qualifying 
dividends which the Fund derives from its portfolio investments which the 
Fund has held for a minimum period, usually 46 days. Any distributions made 
by the Fund will not be eligible for the dividends received deduction with 
respect to shares which are held by the shareholder for 45 days or less. Any 
long-term capital gain distributions will also not be eligible for the 
dividends received deduction. The ability to take the dividends received 
deduction will also be limited in the case of a Fund shareholder which incurs 
or continues indebtedness which is directly attributable to its investment in 
the Fund. 

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

   Shareholders are urged to consult their attorneys or tax advisers 
regarding specific questions as to federal, state or local taxes. 

PERFORMANCE INFORMATION 
- ----------------------------------------------------------------------------- 

   
   As discussed in the Prospectus, from time to time the Fund may quote its 
"total return" in advertisements and sales literature. These figures are 
computed separately for Class A, Class B, Class C and Class D shares. The 
Fund's "average annual total return" represents an annualization of the 
Fund's total return over a specified period and is computed by finding the 
annual percentage rate which will result in the ending redeemable value of a 
hypothetical $1,000 investment made at the beginning of a one, five or ten 
year period, or for the period from the date of commencement of the Fund's 
operations, if shorter than any of the foregoing. The ending redeemable value 
is reduced by any CDSC at the end of the one, five or ten year or other 
period. For the purpose of this calculation, it is assumed that all dividends 
and distributions are reinvested. The formula for computing the average 
annual total return involves a percentage obtained by dividing the ending 
redeemable value by the amount of the initial investment, taking a root of 
the quotient (where the root is equivalent to the number of years in the 
period) and subtracting 1 from the result. The average annual total returns 
of the Fund for the one, five and ten year periods ended September 30, 1996 
were 12.53%, 17.86% and 14.24%, respectively. These returns are for Class B 
only; there were no other Classes of shares outstanding on such date. 

   In addition to the foregoing, the Fund may advertise its total return 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 imposition of the maximum front-end sales charge for 
Class A or the deduction of the CDSC for each of Class B and Class C which, 
if reflected, would reduce the performance quoted. For example, the average 
annual total return of the Fund may be calculated in the manner described in 
the preceding paragraph, but without deduction for any applicable sales 
charge. Based on this calculation, the average annual total returns of the 
Fund for the one, five and ten year periods ended September 30, 1996 were 
17.53%, 18.06% and 14.24%, respectively. These returns are for Class B only; 
there were no other Classes of shares outstanding on such date. 

   In addition, the Fund may compute its aggregate total return for each 
Class for specified periods by determining the aggregate percentage rate 
which will result in the ending value of a hypothetical $1,000 investment 
made at the beginning of the period. For the purpose of this calculation, it 
is assumed that all dividends and distributions are reinvested. The formula 
for computing aggregate total return involves a percentage obtained by 
dividing the ending value (without reduction for any sales charge) by the 
initial $1,000 investment and subtracting 1 from the result. Based on the 
foregoing calculation, the Fund's total return for the year ended September 
30, 1996 was 17.53%, the total return for the five-year period ended 
    

                               31           
<PAGE>
   
September 30, 1996 was 129.38%, and the total return for the ten-year period 
ended September 30, 1996 was 278.50%. These returns are for Class B only; 
there were no other Classes of shares outstanding on such date. 

   The Fund may also advertise the growth of hypothetical investments of 
$10,000, $50,000 and $100,000 in each Class of shares of the Fund by adding 1 
to the Fund's aggregate total return to date (expressed as a decimal and 
without taking into account the effect of any applicable CDSC) and 
multiplying by $9,475, $48,000 and $97,000 in the case of Class A 
(investments of $10,000, $50,000 and $100,000 adjusted for the initial sales 
charge) or by $10,000, $50,000 and $100,000 in the case of each of Class B, 
Class C and Class D, as the case may be. Investments of $10,000, $50,000 and 
$100,000 in the Fund at inception would have grown to $33,935, $169,675 and 
$339,350, respectively, at September 30, 1996. This information is for Class 
B only; there were no other Classes of shares outstanding on such date. 
    

   The Fund from time to time may also advertise its performance relative to 
certain performance rankings and indexes compiled by independent 
organizations. 

DESCRIPTION OF SHARES OF THE FUND 
- ----------------------------------------------------------------------------- 

   
   The shareholders of the Fund are entitled to a full vote for each full 
share held. All of the Trustees have been elected by the shareholders of the 
Fund, most recently at a Special Meeting of Shareholders held on May 21, 
1997. On that date, Wayne E. Hedien was also elected as a Trustee of the 
Fund, with his term to commence on September 1, 1997. The Trustees themselves 
have the power to alter the number and the terms of office of the Trustees, 
and they may at any time lengthen their own terms or make their terms of 
unlimited duration and appoint their own successors, provided that always at 
least a majority of the Trustees has been elected by the shareholders of the 
Fund. Under certain circumstances the Trustees may be removed by action of 
the Trustees. The shareholders also have the right under certain 
circumstances to remove the Trustees. The voting rights of shareholders are 
not cumulative, so that holders of more than 50 percent of the shares voting 
can, if they choose, elect all Trustees being selected, while the holders of 
the remaining shares would be unable to elect any Trustees. 

   The Declaration of Trust permits the Trustees to authorize the creation of 
additional series of shares (the proceeds of which would be invested in 
separate, independently managed portfolios) and additional classes of shares 
within any series (which would be used to distinguish among the rights of 
different categories of shareholders, as might be required by future 
regulations or other unforeseen circumstances). The Trustees have not 
authorized any such additional series or classes of shares other than as set 
forth in the Prospectus. 
    

   The Declaration of Trust provides that no Trustee, officer, employee or 
agent of the Fund is liable to the Fund or to a shareholder, nor is any 
Trustee, officer, employee or agent liable to any third persons in connection 
with the affairs of the Fund, except as such liability may arise from his/her 
or its own bad faith, willful misfeasance, gross negligence, or reckless 
disregard of his/her or its duties. It also provides that all third persons 
shall look solely to the Fund property for satisfaction of claims arising in 
connection with the affairs of the Fund. With the exceptions stated above, 
the Declaration of Trust provides that a Trustee, officer, employee or agent 
is entitled to be indemnified against all liability in connection with the 
affairs of the Fund. 

   The Fund is authorized to issue an unlimited number of shares of 
beneficial interest. The Fund shall be of unlimited duration, subject to the 
provisions in the Declaration of Trust concerning termination by action of 
the shareholders.

DEAN WITTER DEVELOPING GROWTH SECURITIES TRUST 
NOTES TO FINANCIAL STATEMENTS September 30, 1996 

1. ORGANIZATION AND ACCOUNTING POLICIES 

Dean Witter Developing Growth Securities Trust (the "Fund") is registered 
under the Investment Company Act of 1940, as amended (the "Act"), as a 
diversified, open-end management investment company. The Fund's investment 
objective is long-term capital growth. The Fund was organized as a 
Massachusetts business trust on December 28, 1982 and commenced operations on 
April 29, 1983. 

The preparation of financial statements in accordance with generally accepted 
accounting principles requires management to make estimates and assumptions 
that affect the reported amounts and disclosures. Actual results could differ 
from those estimates. The following is a summary of significant accounting 
policies: 

A. VALUATION OF INVESTMENTS --  -- (1) an equity security listed or traded on 
the New York or American Stock Exchange is valued at its latest sale price on 
that exchange prior to the time when assets are valued; if there were no 
sales that day, the security is valued at the latest bid price; (2) all other 
portfolio securities for which over-the-counter market quotations are readily 
available are valued at the latest available bid price prior to the time of 
valuation; (3) when market quotations are not readily available, including 
circumstances under which it is determined by the Investment Manager that 
sale or bid prices are not reflective of a security's market value, portfolio 
securities are valued at their fair value as determined in good faith under 
procedures established by and under the general supervision of the Trustees 
(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); and (4) short-term debt securities having a maturity date 
of more than sixty days at time of purchase are valued on a mark-to-market 
basis until sixty days prior to maturity and thereafter at amortized cost 
based on their value on the 61st day. Short-term debt securities having a 
maturity date of sixty days or less at the time of purchase are valued at 
amortized cost. 

B. ACCOUNTING FOR INVESTMENTS --  -- Security transactions are accounted for 
on the trade date (date the order to buy or sell is executed). Realized gains 
and losses on security transactions are determined by the identified cost 
method. Dividend income and other distributions are recorded on the 
ex-dividend date. Discounts are accreted over the life of the respective 
securities. Interest income is accrued daily. 

C. FEDERAL INCOME TAX STATUS --  -- It is the Fund's policy to comply with 
the requirements of the Internal Revenue Code applicable to regulated 
investment companies and to distribute all of its taxable income to its 
shareholders. Accordingly, no federal income tax provision is required. 

                               41

NOTES TO FINANCIAL STATEMENTS September 30, 1996, continued 

D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS --  -- The Fund records 
dividends and distributions to its shareholders on the record date. The 
amount of dividends and distributions from net investment income and net 
realized capital gains are determined in accordance with federal income tax 
regulations which may differ from generally accepted accounting principles. 
These "book/tax" differences are either considered temporary or permanent in 
nature. To the extent these differences are permanent in nature, such amounts 
are reclassified within the capital accounts based on their federal tax-basis 
treatment; temporary differences do not require reclassification. Dividends 
and distributions which exceed net investment income and net realized capital 
gains for financial reporting purposes but not for tax purposes are reported 
as dividends in excess of net investment income or distributions in excess of 
net realized capital gains. To the extent they exceed net investment income 
and net realized capital gains for tax purposes, they are reported as 
distributions of paid-in-capital. 

2. INVESTMENT MANAGEMENT AGREEMENT 

Pursuant to an Investment Management Agreement with Dean Witter InterCapital 
Inc. (the "Investment Manager"), the Fund pays the Investment Manager a 
management fee, accrued daily and payable monthly, by applying the following 
annual rates to the net assets of the Fund determined as of the close of each 
business day: 0.50% to the portion of the daily net assets not exceeding $500 
million and 0.475% to the portion of the daily net assets exceeding $500 
million. 

Under the terms of the Agreement, in addition to managing the Fund's 
investments, the Investment Manager maintains certain of the Fund's books and 
records and furnishes, at its own expense, office space, facilities, 
equipment, clerical, bookkeeping and certain legal services and pays the 
salaries of all personnel, including officers of the Fund who are employees 
of the Investment Manager. The Investment Manager also bears the cost of 
telephone services, heat, light, power and other utilities provided to the 
Fund. 

3. PLAN OF DISTRIBUTION 

Shares of the Fund are distributed by Dean Witter Distributors Inc. (the 
"Distributor"), an affiliate of the Investment Manager. The Fund has adopted 
a Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the Act 
pursuant to which the Fund pays the Distributor compensation, accrued daily 
and payable monthly, at an annual rate of 1.0% of the lesser of: (a) the 
average daily aggregate gross sales of the Fund's shares since the Fund's 
inception (not including reinvestment of dividend or capital gain 
distributions) less the average daily aggregate net asset value of the Fund's 
shares redeemed since the Fund's inception upon which a contingent deferred 
sales charge has been imposed or upon which such 

                               42           
<PAGE>
DEAN WITTER DEVELOPING GROWTH SECURITIES TRUST 
NOTES TO FINANCIAL STATEMENTS September 30, 1996, continued 

charge has been waived; or (b) the Fund's average daily net assets. Amounts 
paid under the Plan are paid to the Distributor to compensate it for the 
services provided and the expenses borne by it and others in the distribution 
of the Fund's shares, including the payment of commissions for sales of the 
Fund's shares and incentive compensation to, and expenses of, the account 
executives of Dean Witter Reynolds Inc. ("DWR"), an affiliate of the 
Investment Manager and Distributor, and other employees or selected 
broker-dealers who engage in or support distribution of the Fund's shares or 
who service shareholder accounts, including overhead and telephone expenses, 
printing and distribution of prospectuses and reports used in connection with 
the offering of the Fund's shares to other than current shareholders and 
preparation, printing and distribution of sales literature and advertising 
materials. In addition, the Distributor may be compensated under the Plan for 
its opportunity costs in advancing such amounts, which compensation would be 
in the form of a carrying charge on any unreimbursed expenses incurred by the 
Distributor. 

Although there is no legal obligation for the Fund to pay expenses incurred 
in excess of payments made to the Distributor under the Plan and the proceeds 
of contingent deferred sales charges paid by investors upon redemption of 
shares, if for any reason the Plan is terminated, the Trustees will consider 
at that time the manner in which to treat such expenses. The Distributor has 
advised the Fund that such excess amount, including carrying charges, totaled 
$28,270,501 at September 30, 1996. 

Provided that the Plan continues in effect, any cumulative expenses incurred 
by the Distributor but not yet recovered may be recovered through future 
distribution fees from the Fund and contingent deferred sales charges from 
the Fund's shareholders. 

The Distributor has informed the Fund that for the year ended September 30, 
1996, it received approximately $810,000 in contingent deferred sales charges 
from certain redemptions of the Fund's shares. 

4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES 

The cost of purchases and proceeds from sales of portfolio securities, 
excluding short-term investments, for the year ended September 30, 1996 
aggregated $1,095,944,214 and $881,579,783, respectively. 

For the year ended September 30, 1996, the Fund incurred $133,555 in 
brokerage commissions with DWR for portfolio transactions executed on behalf 
of the Fund. 

The Fund has an unfunded noncontributory defined benefit pension plan 
covering all independent Trustees of the Fund who will have served as 
independent Trustees for at least five years at the time of retirement. 
Benefits under this plan are based on years of service and compensation 
during the last five years of service. Aggregate pension costs for the year 
ended September 30, 1996 included in Trustees' 

                               43

September 30, 1996, the Fund had an accrued pension liability of $39,122 
which is included in accrued expenses in the Statement of Assets and 
Liabilities.

6. FEDERAL INCOME TAX STATUS 

As of September 30, 1996, the Fund had temporary book/tax differences 
primarily attributable to capital loss deferrals on wash sales and permanent 
book/tax differences primarily attributable to a net operating loss. To 
reflect reclassifications arising from permanent book/tax differences for the 
year ended September 30, 1996, accumulated undistributed net realized gain 
was charged $6,660,503, paid-in-capital was credited $36,253 and accumulated 
net investment loss was credited $6,624,250.

REPORT OF INDEPENDENT ACCOUNTANTS 

TO THE SHAREHOLDERS AND TRUSTEES 
OF DEAN WITTER DEVELOPING GROWTH SECURITIES TRUST 

In our opinion, the accompanying statement of assets and liabilities, 
including the portfolio of investments, and the related statements of 
operations and of changes in net assets and the financial highlights present 
fairly, in all material respects, the financial position of Dean Witter 
Developing Growth Securities Trust (the "Fund") at September 30, 1996, the 
results of its operations for the year then ended, the changes in its net 
assets for each of the two years in the period then ended and the financial 
highlights for each of the ten years in the period then ended, in conformity 
with generally accepted accounting principles. These financial statements and 
financial highlights (hereafter referred to as "financial statements") are 
the responsibility of the Fund's management; our responsibility is to express 
an opinion on these financial statements based on our audits. We conducted 
our audits of these financial statements in accordance with generally 
accepted auditing standards which require that we plan and perform the audit 
to obtain reasonable assurance about whether the financial statements are 
free of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements, 
assessing the accounting principles used and significant estimates made by 
management, and evaluating the overall financial statement presentation. We 
believe that our audits, which included confirmation of securities at 
September 30, 1996 by correspondence with the custodian and brokers and the 
application of alternative auditing procedures where confirmations from 
brokers were not received, provide a reasonable basis for the opinion 
expressed above.

DEAN WITTER DEVELOPING GROWTH SECURITIES TRUST 
NOTES TO FINANCIAL STATEMENTS March 31, 1997 (unaudited) 

1. ORGANIZATION AND ACCOUNTING POLICIES 

Dean Witter Developing Growth Securities Trust (the "Fund") is registered 
under the Investment Company Act of 1940, as amended (the "Act"), as a 
diversified, open-end management investment company. The Fund's investment 
objective is long-term capital growth. The Fund was organized as a 
Massachusetts business trust on December 28, 1982 and commenced operations on 
April 29, 1983. 

The preparation of financial statements in accordance with generally accepted 
accounting principles requires management to make estimates and assumptions 
that affect the reported amounts and disclosures. Actual results could differ 
from those estimates. 

The following is a summary of significant accounting policies: 

A. VALUATION OF INVESTMENTS -- (1) an equity security listed or traded on the 
New York, American or other domestic or foreign stock exchange is valued at 
its latest sale price on that exchange prior to the time when assets are 
valued; if there were no sales that day, the security is valued at the latest 
bid price; (2) all other portfolio securities for which over-the-counter 
market quotations are readily available are valued at the latest available 
bid price prior to the time of valuation; (3) when market quotations are not 
readily available, including circumstances under which it is determined by 
Dean Witter InterCapital Inc. (the "Investment Manager") that sale or bid 
prices are not reflective of a security's market value, portfolio securities 
are valued at their fair value as determined in good faith under procedures 
established by and under the general supervision of the Trustees (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); and (4) short-term debt securities having a maturity date of more 
than sixty days at time of purchase are valued on a mark-to-market basis 
until sixty days prior to maturity and thereafter at amortized cost based on 
their value on the 61st day. Short-term debt securities having a maturity 
date of sixty days or less at the time of purchase are valued at amortized 
cost. 

B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on 
the trade date (date the order to buy or sell is executed). Realized gains 
and losses on security transactions are determined by the identified cost 
method. Dividend income and other distributions are recorded on the 
ex-dividend date. Discounts are accreted over the life of the respective 
securities. Interest income is accrued daily. 

C. FEDERAL INCOME TAX STATUS -- It is the Fund's policy to comply with the 
requirements of the Internal Revenue Code applicable to regulated investment 
companies and to distribute all of its taxable income to its shareholders. 
Accordingly, no federal income tax provision is required. 

                               55

NOTES TO FINANCIAL STATEMENTS March 31, 1997 (unaudited) continued 

D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends 
and distributions to its shareholders on the record date. The amount of 
dividends and distributions from net investment income and net realized 
capital gains are determined in accordance with federal income tax 
regulations which may differ from generally accepted accounting principles. 
These "book/tax" differences are either considered temporary or permanent in 
nature. To the extent these differences are permanent in nature, such amounts 
are reclassified within the capital accounts based on their federal tax-basis 
treatment; temporary differences do not require reclassification. Dividends 
and distributions which exceed net investment income and net realized capital 
gains for financial reporting purposes but not for tax purposes are reported 
as dividends in excess of net investment income or distributions in excess of 
net realized capital gains. To the extent they exceed net investment income 
and net realized capital gains for tax purposes, they are reported as 
distributions of paid-in-capital. 

2. INVESTMENT MANAGEMENT AGREEMENT 

Pursuant to an Investment Management Agreement, the Fund pays the Investment 
Manager a management fee, accrued daily and payable monthly, by applying the 
following annual rates to the net assets of the Fund determined as of the 
close of each business day: 0.50% to the portion of the daily 
net assets not exceeding $500 million and 0.475% to the portion of the daily 
net assets exceeding 
$500 million. 

Under the terms of the Agreement, in addition to managing the Fund's 
investments, the Investment Manager maintains certain of the Fund's books and 
records and furnishes, at its own expense, office space, facilities, 
equipment, clerical, bookkeeping and certain legal services and pays the 
salaries of all personnel, including officers of the Fund who are employees 
of the Investment Manager. The Investment Manager also bears the cost of 
telephone services, heat, light, power and other utilities provided to the 
Fund. 

3. PLAN OF DISTRIBUTION 

Shares of the Fund are distributed by Dean Witter Distributors Inc. (the 
"Distributor"), an affiliate of the Investment Manager. The Fund has adopted 
a Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the Act 
pursuant to which the Fund pays the Distributor compensation, accrued daily 
and payable monthly, at an annual rate of 1.0% of the lesser of: (a) the 
average daily aggregate gross sales of the Fund's shares since the Fund's 
inception (not including reinvestment of dividend or capital gain 
distributions) less the average daily aggregate net asset value of the Fund's 
shares redeemed since the Fund's inception upon which a contingent deferred 
sales charge has been imposed or upon which such

DEAN WITTER DEVELOPING GROWTH SECURITIES TRUST 
NOTES TO FINANCIAL STATEMENTS March 31, 1997 (unaudited) continued 

charge has been waived; or (b) the Fund's average daily net assets. Amounts 
paid under the Plan are paid to the Distributor to compensate it for the 
services provided and the expenses borne by it and others in the distribution 
of the Fund's shares, including the payment of commissions for sales of the 
Fund's shares and incentive compensation to, and expenses of, the account 
executives of Dean Witter Reynolds Inc. ("DWR"), an affiliate of the 
Investment Manager and Distributor, and other employees or selected 
broker-dealers who engage in or support distribution of the Fund's shares or 
who service shareholder accounts, including overhead and telephone expenses, 
printing and distribution of prospectuses and reports used in connection with 
the offering of the Fund's shares to other than current shareholders and 
preparation, printing and distribution of sales literature and advertising 
materials. In addition, the Distributor may be compensated under the Plan for 
its opportunity costs in advancing such amounts, which compensation would be 
in the form of a carrying charge on any unreimbursed expenses incurred by the 
Distributor. 

Provided that the Plan continues in effect, any cumulative expenses incurred 
by the Distributor but not yet recovered may be recovered through future 
distribution fees from the Fund and contingent deferred sales charges from 
the Fund's shareholders. 

Although there is no legal obligation for the Fund to pay expenses incurred 
in excess of payments made to the Distributor under the Plan and the proceeds 
of contingent deferred sales charges paid by investors upon redemption of 
shares, if for any reason the Plan is terminated, the Trustees will consider 
at that time the manner in which to treat such expenses. The Distributor has 
advised the Fund that such excess amounts, including carrying charges, 
totaled $28,825,782 at March 31, 1997. 

The Distributor has informed the Fund that for the six months ended March 31, 
1997, it received approximately $638,000 in contingent deferred sales charges 
from certain redemptions of the Fund's shares. 

4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES 

The cost of purchases and proceeds from sales of portfolio securities, 
excluding short-term investments, for the six months ended March 31, 1997 
aggregated $551,762,905 and $634,925,811, respectively. 

For the six months ended March 31, 1997, the Fund incurred $28,599 in 
brokerage commissions with DWR for portfolio transactions executed on behalf 
of the Fund. At March 31, 1997, the Fund's receivable for investments sold 
included unsettled trades with DWR of $1,298,375. 

The Fund has an unfunded noncontributory defined benefit pension plan 
covering all independent Trustees of the Fund who will have served as 
independent Trustees for at least five years at the time of retirement. 
Benefits under this plan are based on years of service and compensation 
during the last five

Item 27. Indemnification.

     Pursuant to Section 5.3 of the Registrant's Declaration of Trust and under
Section 4.8 of the Registrant's By-Laws, the indemnification of the Registrant's
trustees, officers, employees and agents is permitted if it is determined that
they acted under the belief that their actions were in or not opposed to the
best interest of the Registrant, and, with respect to any criminal proceeding,
they had reasonable cause to believe their conduct was not unlawful. In
addition, indemnification is permitted only if it is determined that the actions
in question did not render them liable by reason of willful misfeasance, bad
faith or gross negligence in the performance of their duties or by reason of
reckless disregard of their obligations and duties to the Registrant. Trustees,
officers, employees and agents will be indemnified for the expense of litigation
if it is determined that they are entitled to indemnification against any
liability established in such litigation. The Registrant may also advance money
for these expenses provided that they give their undertakings to repay the
Registrant unless their conduct is later determined to permit indemnification.

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

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

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

                                       3

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

                            PURSUANT TO RULE 18F-3 

   INTRODUCTION

   This plan (the "Plan") is adopted pursuant to Rule 18f-3(d) of the 
Investment Company Act of 1940, as amended (the "1940 Act"), and will be 
effective as of July 28, 1997. The Plan relates to shares of the open-end 
investment companies to which Dean Witter InterCapital Inc. acts as 
investment manager, that are listed on Schedule A, as may be amended from 
time to time (each, a "Fund" and collectively, the "Funds"). The Funds are 
distributed pursuant to a system (the "Multiple Class System") in which each 
class of shares (each, a "Class" and collectively, the "Classes") of a Fund 
represents a pro rata interest in the same portfolio of investments of the 
Fund and differs only to the extent outlined below. 

I. DISTRIBUTION ARRANGEMENTS 

   One or more Classes of shares of the Funds are offered for purchase by 
investors with the sales load structures described below. In addition, 
pursuant to Rule 12b-1 under the 1940 Act, the Funds have each adopted a Plan 
of Distribution (the "12b-1 Plan") under which shares of certain Classes are 
subject to the service and/or distribution fees ("12b-1 fees") described 
below. 

   1. Class A Shares 

   Class A shares are offered with a front-end sales load ("FESL"). The 
schedule of sales charges applicable to a Fund and the circumstances under 
which the sales charges are subject to reduction are set forth in each Fund's 
current prospectus. As stated in each Fund's current prospectus, Class A 
shares may be purchased at net asset value (without a FESL): (i) in the case 
of certain large purchases of such shares; and (ii) by certain limited 
categories of investors, in each case, under the circumstances and conditions 
set forth in each Fund's current prospectus. Class A shares purchased at net 
asset value may be subject to a contingent deferred sales charge ("CDSC") on 
redemptions made within one year of purchase. Further information relating to 
the CDSC, including the manner in which it is calculated, is set forth in 
paragraph 6 below. Class A shares are also subject to payments under each 
Fund's 12b-1 Plan to reimburse Dean Witter Distributors Inc., Dean Witter 
Reynolds Inc. ("DWR"), its affiliates and other broker-dealers for 
distribution expenses incurred by them specifically on behalf of the Class, 
assessed at an annual rate of up to 0.25% of average daily net assets. The 
entire amount of the 12b-1 fee represents a service fee within the meaning of 
National Association of Securities Dealers, Inc. ("NASD") guidelines. 

   2. Class B Shares 

   Class B shares are offered without a FESL, but will in most cases be 
subject to a six-year declining CDSC which is calculated in the manner set 
forth in paragraph 6 below. Class B shares purchased by certain qualified 
employer-sponsored benefit plans are subject to a three-year declining CDSC 
which is calculated in the manner set forth in paragraph 6 below. The 
schedule of CDSC charges applicable to each Fund is set forth in each Fund's 
current prospectus. With the exception of certain of the Funds which have a 
different formula described below (Dean Witter American Value Fund, Dean 
Witter Natural Resource Development Securities Inc., Dean Witter Strategist 
Fund and Dean Witter Dividend Growth Securities 

                                1           
<PAGE>

Inc.) (1), Class B shares are also subject to a fee under each Fund's 
respective 12b-1 Plan, assessed at the annual rate of up to 1.0% of either: 
(a) the lesser of (i) the average daily aggregate gross sales of the Fund's 
Class B shares since the inception of the Fund (not including reinvestment of 
dividends or capital gains distributions), less the average daily aggregate 
net asset value of the Fund's Class B shares redeemed since the Fund's 
inception upon which a CDSC has been imposed or waived, or (ii) the average 
daily net assets of Class B; or (b) the average daily net assets of Class B. 
A portion of the 12b-1 fee equal to up to 0.25% of the Fund's average daily 
net assets is characterized as a service fee within the meaning of the NASD 
guidelines and the remaining portion of the 12b-1 fee, if any, is 
characterized as an asset-based sales charge. Also, Class B shares have a 
conversion feature ("Conversion Feature") under which such shares convert to 
Class A shares after a certain holding period. Details of the Conversion 
Feature are set forth in Section IV below. 

   3. Class C Shares 

   Class C shares are offered without imposition of a FESL, but will in most 
cases be subject to a CDSC of 1.0% on redemptions made within one year after 
purchase. Further information relating to the CDSC is set forth in paragraph 
6 below. In addition, Class C shares, under each Fund's 12b-1 Plan, are 
subject to 12b-1 payments to reimburse Dean Witter Distributors Inc., DWR, 
its affiliates and other broker-dealers for distribution expenses incurred by 
them specifically on behalf of the Class, assessed at the annual rate of up 
to 1.0% of the average daily net assets of the Class. A portion of the 12b-1 
fee equal to up to 0.25% of the Fund's average daily net assets is 
characterized as a service fee within the meaning of NASD guidelines. Unlike 
Class B shares, Class C shares do not have the Conversion Feature. 

   4. Class D Shares 

   Class D shares are offered without imposition of a FESL, CDSC or a 12b-1 
fee for purchases of Fund shares by (i) investors meeting an initial minimum 
investment requirement and (ii) certain other limited categories of 
investors, in each case, as may be approved by the Boards of 
Directors/Trustees of the Funds and as disclosed in each Fund's current 
prospectus. 

   5. Additional Classes of Shares 

   The Boards of Directors/Trustees of the Funds have the authority to create 
additional Classes, or change existing Classes, from time to time, in 
accordance with Rule 18f-3 under the 1940 Act. 

   6. Calculation of the CDSC 

   Any applicable CDSC is calculated based upon the lesser of net asset value 
of the shares at the time of purchase or at the time of redemption. The CDSC 
does not apply to amounts representing an increase in share value due to 
capital appreciation and shares acquired through the reinvestment of 
dividends or 

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

(1)The payments under the 12b-1 Plan for each of Dean Witter American Value 
Fund, Dean Witter Natural Resource Development Securities Inc. and Dean 
Witter Dividend Growth Securities Inc. are assessed at the annual rate of 
1.0% of the lesser of: (a) the average daily aggregate gross sales of the 
Fund's Class B shares since the inception of the Fund's Plan (not including 
reinvestment of dividends or capital gains distributions), less the average 
daily aggregate net asset value of the Fund's Class B shares redeemed since 
the Plan's inception upon which a contingent deferred sales charge has been 
imposed or waived, or (b) the average daily net assets of Class B 
attributable to shares issued, net of related shares redeemed, since 
inception of the Plan. The payments under the 12b-1 Plan for the Dean Witter 
Strategist Fund are assessed at the annual rate of: (i) 1% of the lesser of 
(a) the average daily aggregate gross sales of the Fund's Class B shares 
since the effectiveness of the first amendment of the Plan on November 8, 
1989 (not including reinvestment of dividends or capital gains 
distributions), less the average daily aggregate net asset value of the 
Fund's Class B shares redeemed since the effectiveness of the first amended 
Plan, upon which a contingent deferred sales charge has been imposed or 
waived, or (b) the average daily net assets of Class B attributable to shares 
issued, net of related shares redeemed, since the effectiveness of the first 
amended Plan; plus (ii) 0.25% of the average daily net assets of Class B 
attributable to shares issued, net of related shares redeemed, prior to 
effectiveness of the first amended Plan. 


                                2           
<PAGE>
capital gains distributions. The CDSC schedule applicable to a Fund and the 
circumstances in which the CDSC is subject to waiver are set forth in each 
Fund's prospectus. 

II. EXPENSE ALLOCATIONS 

   Expenses incurred by a Fund are allocated among the various Classes of 
shares pro rata based on the net assets of the Fund attributable to each 
Class, except that 12b-1 fees relating to a particular Class are allocated 
directly to that Class. In addition, other expenses associated with a 
particular Class (except advisory or custodial fees), may be allocated 
directly to that Class, provided that such expenses are reasonably identified 
as specifically attributable to that Class and the direct allocation to that 
Class is approved by the Fund's Board of Directors/Trustees. 

III. CLASS DESIGNATION 

   All shares of the Funds held prior to July 28, 1997 (other than the shares 
held by certain employee benefit plans established by DWR and its affiliate, 
SPS Transaction Services, Inc., shares of Funds offered with a FESL, and 
shares of Dean Witter Balanced Growth Fund and Dean Witter Balanced Income 
Fund) have been designated Class B shares. Shares held prior to July 28, 1997 
by such employee benefit plans have been designated Class D shares. Shares 
held prior to July 28, 1997 of Funds offered with a FESL have been designated 
Class D shares. In addition, shares of Dean Witter American Value Fund 
purchased prior to April 30, 1984, shares of Dean Witter Strategist Fund 
purchased prior to November 8, 1989 and shares of Dean Witter Natural 
Resource Development Securities Inc. and Dean Witter Dividend Growth 
Securities Inc. purchased prior to July 2, 1984 (with respect to such shares 
of each Fund, including such proportion of shares acquired through 
reinvestment of dividends and capital gains distributions as the total number 
of shares acquired prior to each of the preceding dates in this sentence 
bears to the total number of shares purchased and owned by the shareholder of 
that Fund) have been designated Class D shares. Shares of Dean Witter 
Balanced Growth Fund and Dean Witter Balanced Income Fund held prior to July 
28, 1997 have been designated Class C shares except that shares of Dean 
Witter Balanced Growth Fund and Dean Witter Balanced Income Fund held prior 
to July 28, 1997 that were acquired in exchange for shares of an investment 
company offered with a CDSC have been designated Class B shares and those 
that were acquired in exchange for shares of an investment company offered 
with a FESL have been designated Class A shares. 

IV. THE CONVERSION FEATURE 

   Class B shares held before May 1, 1997 will convert to Class A shares in 
May, 2007, except that Class B shares which are purchased before July 28, 
1997 by trusts for which Dean Witter Trust Company ("DWTC") or Dean Witter 
Trust FSB ("DWTFSB") provides discretionary trustee services will convert to 
Class A shares on or about August 29, 1997 (the CDSC will not be applicable 
to such shares upon the conversion). In all other instances, Class B shares 
of each Fund will automatically convert to Class A shares, based on the 
relative net asset values of the shares of the two Classes on the conversion 
date, which will be approximately ten (10) years after the date of the 
original purchase. Conversions will be effected once a month. The 10 year 
period will be calculated from the last day of the month in which the shares 
were purchased or, in the case of Class B shares acquired through an exchange 
or a series of exchanges, from the last day of the month in which the 
original Class B shares were purchased, provided that shares originally 
purchased before May 1, 1997 will convert to Class A shares in May, 2007. 
Except as set forth below, the conversion of shares purchased on or after May 
1, 1997 will take place in the month following the tenth anniversary of the 
purchase. There will also be converted at that time such proportion of Class 
B shares acquired through automatic reinvestment of dividends owned by the 
shareholder as the total number of his or her Class B shares converting at 
the time bears to the total number of outstanding Class B shares purchased 
and owned by the shareholder. In the case of Class B shares held by a 401(k) 
plan or other employer-sponsored plan qualified under Section 401(a) of the 
Internal Revenue Code (the "Code") and for which DWTC or DWTFSB serves as 
Trustee or the 401(k) Support Services Group of DWR serves as recordkeeper, 
all Class B shares will convert to Class A shares on the conversion date of 
the first shares of a Fund purchased by that plan. In the case of Class B 
shares previously exchanged 

                                3           
<PAGE>
for shares of an "Exchange Fund" (as such term is defined in the prospectus 
of each Fund), the period of time the shares were held in the Exchange Fund 
(calculated from the last day of the month in which the Exchange Fund shares 
were acquired) is excluded from the holding period for conversion. If those 
shares are subsequently re-exchanged for Class B shares of a Fund, the 
holding period resumes on the last day of the month in which Class B shares 
are reacquired. 

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

V. EXCHANGE PRIVILEGES 

   Shares of each Class may be exchanged for shares of the same Class of the 
other Funds and for shares of certain other investment companies without the 
imposition of an exchange fee as described in the prospectuses and statements 
of additional information of the Funds. The exchange privilege of each Fund 
may be terminated or revised at any time by the Fund upon such notice as may 
be required by applicable regulatory agencies as described in each Fund's 
prospectus. 

VI. VOTING 

   Each Class shall have exclusive voting rights on any matter that relates 
solely to its 12b-1 Plan, except that Class B shareholders will have the 
right to vote on any proposed material increase in Class A's expenses, 
including payments under the Class A 12b-1 Plan, if such proposal is 
submitted separately to Class A shareholders. If the amount of expenses, 
including payments under the Class A 12b-1 Plan, is increased materially 
without the approval of Class B shareholders, the Fund will establish a new 
Class A for Class B shareholders whose shares automatically convert on the 
same terms as applied to Class A before the increase. In addition, each Class 
shall have separate voting rights on any matter submitted to shareholders in 
which the interests of one Class differ from the interests of any other 
Class.

                       INVESTMENT MANAGEMENT AGREEMENT 

   AGREEMENT made as of the 31st day of May, 1997 by and between Dean Witter 
Developing Growth Securities Trust, an unincorporated business trust 
organized under the laws of the Commonwealth of Massachusetts (hereinafter 
called the "Fund"), and Dean Witter InterCapital Inc., a Delaware corporation 
(hereinafter called the "Investment Manager"): 

   WHEREAS, The Fund is engaged in business as an open-end management 
investment company and is registered as such under the Investment Company Act 
of 1940, as amended (the "Act"); and 

   WHEREAS, The Investment Manager is registered as an investment adviser 
under the Investment Advisers Act of 1940, and engages in the business of 
acting as investment adviser; and 

   WHEREAS, The Fund desires to retain the Investment Manager to render 
management and investment advisory services in the manner and on the terms 
and conditions hereinafter set forth; and 

   WHEREAS, The Investment Manager desires to be retained to perform services 
on said terms and conditions: 

   Now, Therefore, this Agreement 

                             W I T N E S S E T H: 

that in consideration of the premises and the mutual covenants hereinafter 
contained, the Fund and the Investment Manager agree as follows: 

   1. The Fund hereby retains the Investment Manager to act as investment 
manager of the Fund and, subject to the supervision of the Trustees, to 
supervise the investment activities of the Fund as hereinafter set forth. 
Without limiting the generality of the foregoing, the Investment Manager 
shall obtain and evaluate such information and advice relating to the 
economy, securities and commodities markets and securities and commodities as 
it deems necessary or useful to discharge its duties hereunder; shall 
continuously manage the assets of the Fund in a manner consistent with the 
investment objectives and policies of the Fund; shall determine the 
securities and commodities to be purchased, sold or otherwise disposed of by 
the Fund and the timing of such purchases, sales and dispositions; and shall 
take such further action, including the placing of purchase and sale orders 
on behalf of the Fund, as the Investment Manager shall deem necessary or 
appropriate. The Investment Manager shall also furnish to or place at the 
disposal of the Fund such of the information, evaluations, analyses and 
opinions formulated or obtained by the Investment Manager in the discharge of 
its duties as the Fund may, from time to time, reasonably request. 

   2. The Investment Manager shall, at its own expense, maintain such staff 
and employ or retain such personnel and consult with such other persons as it 
shall from time to time determine to be necessary or useful to the 
performance of its obligations under this Agreement. Without limiting the 
generality of the foregoing, the staff and personnel of the Investment 
Manager shall be deemed to include persons employed or otherwise retained by 
the Investment Manager to furnish statistical and other factual data, advice 
regarding economic factors and trends, information with respect to technical 
and scientific developments, and such other information, advice and 
assistance as the Investment Manager may desire. The Investment Manager 
shall, as agent for the Fund, maintain the Fund's records and books of 
account (other than those maintained by the Fund's transfer agent, registrar, 
custodian and other agencies). All such books and records so maintained shall 
be the property of the Fund and, upon request therefor, the Investment 
Manager shall surrender to the Fund such of the books and records so 
requested. 

   3. The Fund will, from time to time, furnish or otherwise make available 
to the Investment Manager such financial reports, proxy statements and other 
information relating to the business and affairs of the Fund as the 
Investment Manager may reasonably require in order to discharge its duties 
and obligations hereunder. 

   4. The Investment Manager shall bear the cost of rendering the investment 
management and supervisory services to be performed by it under this 
Agreement, and shall, at its own expense, pay the compensation of the 
officers and employees, if any, of the Fund, and provide such office space, 
facilities and equipment 



<PAGE>

and such clerical help and bookkeeping services as the Fund shall reasonably 
require in the conduct of its business. The Investment Manager shall also bear 
the cost of telephone service, heat, light, power and other utilities provided 
to the Fund. 

   5. The Fund assumes and shall pay or cause to be paid all other expenses 
of the Fund, including without limitation: fees pursuant to any plan of 
distribution that the Fund may adopt; the charges and expenses of any 
registrar, any custodian or depository appointed by the Fund for the 
safekeeping of its cash, portfolio securities or commodities and other 
property, and any stock transfer or dividend agent or agents appointed by the 
Fund; brokers' commissions chargeable to the Fund in connection with 
portfolio transactions to which the Fund is a party; all taxes, including 
securities or commodities issuance and transfer taxes, and fees payable by 
the Fund to federal, state or other governmental agencies; the cost and 
expense of engraving or printing certificates representing shares of the 
Fund; all costs and expenses in connection with the registration and 
maintenance of registration of the Fund and its shares with the Securities 
and Exchange Commission and various states and other jurisdictions (including 
filing fees and legal fees and disbursements of counsel); the cost and 
expense of printing, including typesetting, and distributing prospectuses and 
statements of additional information of the Fund and supplements thereto to 
the Fund's shareholders; all expenses of shareholders' and Trustees' meetings 
and of preparing, printing and mailing proxy statements and reports to 
shareholders; fees and travel expenses of Trustees or members of any advisory 
board or committee who are not employees of the Investment Manager or any 
corporate affiliate of the Investment Manager; all expenses incident to the 
payment of any dividend, distribution, withdrawal or redemption, whether in 
shares or in cash; charges and expenses of any outside service used for 
pricing of the Fund's shares; charges and expenses of legal counsel, 
including counsel to the Trustees of the Fund who are not interested persons 
(as defined in the Act) of the Fund or the Investment Manager, and of 
independent accountants, in connection with any matter relating to the Fund; 
membership dues of industry associations; interest payable on Fund 
borrowings; postage; insurance premiums on property or personnel (including 
officers and Trustees) of the Fund which inure to its benefit; extraordinary 
expenses (including but not limited to legal claims and liabilities and 
litigation costs and any indemnification related thereto); and all other 
charges and costs of the Fund's operation unless otherwise explicitly 
provided herein. 

   6. For the services to be rendered, the facilities furnished, and the 
expenses assumed by the Investment Manager, the Fund shall pay to the 
Investment Manager monthly compensation determined by applying the following 
annual rates to the Fund's daily net assets: 0.50% of daily net assets up to 
$500 million; and 0.475% of daily net assets over $500 million. Except as 
hereinafter set forth, compensation under this Agreement shall be calculated 
and accrued daily and the amounts of the daily accruals shall be paid 
monthly. Such calculations shall be made by applying 1/365ths of the annual 
rates to the Fund's net assets each day determined as of the close of 
business on that day or the last previous business day. If this Agreement 
becomes effective subsequent to the first day of a month or shall terminate 
before the last day of a month, compensation for that part of the month this 
Agreement is in effect shall be prorated in a manner consistent with the 
calculation of the fees as set forth above. 

   Subject to the provisions of paragraph 7 hereof, payment of the Investment 
Manager's compensation for the preceding month shall be made as promptly as 
possible after completion of the computations contemplated by paragraph 7 
hereof. 

   7. In the event the operating expenses of the Fund, including amounts 
payable to the Investment Manager pursuant to paragraph 6 hereof, for any 
fiscal year ending on a date on which this Agreement is in effect, exceed the 
expense limitations applicable to the Fund imposed by state securities laws 
or regulations thereunder, as such limitations may be raised or lowered from 
time to time, the Investment Manager shall reduce its management fee to the 
extent of such excess and, if required, pursuant to any such laws or 
regulations, will reimburse the Fund for annual operating expenses in excess 
of any expense limitation that may be applicable; provided, however, there 
shall be excluded from such expenses the amount of any interest, taxes, 
brokerage commissions, distribution fees and extraordinary expenses 
(including but not limited to legal claims and liabilities and litigation 
costs and any indemnification related thereto) paid or payable by the Fund. 
Such reduction, if any, shall be computed and accrued daily, shall be settled 
on a monthly basis, and shall be based upon the expense limitation applicable 
to the Fund as at the end of the last 

                                2
<PAGE>

business day of the month. Should two or more such expense limitations be 
applicable as at the end of the last business day of the month, that expense 
limitation which results in the largest reduction in the Investment Manager's 
fee shall be applicable. 

   For purposes of this provision, should any applicable expense limitation 
be based upon the gross income of the Fund, such gross income shall include, 
but not be limited to, interest on debt securities in the Fund's portfolio 
accrued to and including the last day of the Fund's fiscal year, and 
dividends declared on equity securities in the Fund's portfolio, the record 
dates for which fall on or prior to the last day of such fiscal year, but 
shall not include gains from the sale of securities. 
                                
   8. The Investment Manager will use its best efforts in the supervision and 
management of the investment activities of the Fund, but in the absence of 
willful misfeasance, bad faith, gross negligence or reckless disregard of its 
obligations hereunder, the Investment Manager shall not be liable to the Fund 
or any of its investors for any error of judgment or mistake of law or for 
any act or omission by the Investment Manager or for any losses sustained by 
the Fund or its investors. 

   9. Nothing contained in this Agreement shall prevent the Investment 
Manager or any affiliated person of the Investment Manager from acting as 
investment adviser or manager for any other person, firm or corporation and 
shall not in any way bind or restrict the Investment Manager or any such 
affiliated person from buying, selling or trading any securities or 
commodities for their own accounts or for the account of others for whom they 
may be acting. Nothing in this Agreement shall limit or restrict the right of 
any Trustee, officer or employee of the Investment Manager to engage in any 
other business or to devote his or her time and attention in part to the 
management or other aspects of any other business whether of a similar or 
dissimilar nature. 

   10. This Agreement shall remain in effect until April 30, 1999 and from 
year to year thereafter provided such continuance is approved at least 
annually by the vote of holders of a majority, as defined in the Investment 
Company Act of 1940, as amended (the "Act"), of the outstanding voting 
securities of the Fund or by the Trustees of the Fund; provided that in 
either event such continuance is also approved annually by the vote of a 
majority of the Trustees of the Fund who are not parties to this Agreement or 
"interested persons" (as defined in the Act) of any such party, which vote 
must be cast in person at a meeting called for the purpose of voting on such 
approval; provided, however, that (a) the Fund may, at any time and without 
the payment of any penalty, terminate this Agreement upon thirty days' 
written notice to the Investment Manager, either by majority vote of the 
Trustees of the Fund or by the vote of a majority of the outstanding voting 
securities of the Fund; (b) this Agreement shall immediately terminate in the 
event of its assignment (to the extent required by the Act and the rules 
thereunder) unless such automatic terminations shall be prevented by an 
exemptive order of the Securities and Exchange Commission; and (c) the 
Investment Manager may terminate this Agreement without payment of penalty on 
thirty days' written notice to the Fund. Any notice under this Agreement 
shall be given in writing, addressed and delivered, or mailed post-paid, to 
the other party at the principal office of such party. 

   11. This Agreement may be amended by the parties without the vote or 
consent of the shareholders of the Fund to supply any omission, to cure, 
correct or supplement any ambiguous, defective or inconsistent provision 
hereof, or if they deem it necessary to conform this Agreement to the 
requirements of applicable federal laws or regulations, but neither the Fund 
nor the Investment Manager shall be liable for failing to do so. 

   12. This Agreement shall be construed in accordance with the laws of the 
State of New York and the applicable provisions of the Act. To the extent the 
applicable law of the State of New York, or any of the provisions herein, 
conflicts with the applicable provisions of the Act, the latter shall 
control. 

   13. The Investment Manager and the Fund each agree that the name "Dean 
Witter," which comprises a component of the Fund's name, is a property right 
of Dean Witter Reynolds Inc. The Fund agrees and consents that (i) it will 
only use the name "Dean Witter" as a component of its name and for no other 
purpose, (ii) it will not purport to grant to any third party the right to

                              DEAN WITTER FUNDS 

                            DISTRIBUTION AGREEMENT 

   AGREEMENT made as of this 31st day of May, 1997 between each of the 
open-end investment companies to which Dean Witter InterCapital Inc. acts as 
investment manager, that are listed on Schedule A, as may be amended from 
time to time (each, a "Fund" and collectively, the "Funds"), and Dean Witter 
Distributors Inc., a Delaware corporation (the "Distributor"). 

                             W I T N E S S E T H: 

   WHEREAS, each Fund is registered as an open-end investment company under 
the Investment Company Act of 1940, as amended (the "1940 Act"), and it is in 
the interest of each Fund to offer its shares for sale continuously, and 

   WHEREAS, each Fund and the Distributor wish to enter into an agreement 
with each other with respect to the continuous offering of each Fund's 
transferable shares, of $0.01 par value (the "Shares"), to commence on the 
date listed above, in order to promote the growth of each Fund and facilitate 
the distribution of its shares. 

   NOW, THEREFORE, the parties agree as follows: 

   SECTION 1. Appointment of the Distributor. 

   (a) Each Fund hereby appoints the Distributor as the principal underwriter 
and distributor of the Fund to sell Shares to the public on the terms set 
forth in this Agreement and that Fund's prospectus and the Distributor hereby 
accepts such appointment and agrees to act hereunder. Each Fund, during the 
term of this Agreement, shall sell Shares to the Distributor upon the terms 
and conditions set forth herein. 

   (b) The Distributor agrees to purchase Shares, as principal for its own 
account, from each Fund and to sell Shares as principal to investors, and 
securities dealers, including Dean Witter Reynolds Inc. ("DWR"), an affiliate 
of the Distributor, upon the terms described herein and in that Fund's 
prospectus (the "Prospectus") and statement of additional information 
included in the Fund's registration statement (the "Registration Statement") 
most recently filed from time to time with the Securities and Exchange 
Commission (the "SEC") and effective under the Securities Act of 1933, as 
amended (the "1933 Act"), and the 1940 Act or as the Prospectus may be 
otherwise amended or supplemented and filed with the SEC pursuant to Rule 497 
under the 1933 Act. 

   SECTION 2 Exclusive Nature of Duties. The Distributor shall be the 
exclusive principal underwriter and distributor of each Fund, except that the 
exclusive rights granted to the Distributor to sell the Shares shall not 
apply to Shares issued by each Fund: (i) in connection with the merger or 
consolidation of any other investment company or personal holding company 
with the Fund or the acquisition by purchase or otherwise of all (or 
substantially all) the assets or the outstanding shares of any such company 
by the Fund; (ii) pursuant to reinvestment of dividends or capital gains 
distributions; or (iii) pursuant to the reinstatement privilege afforded 
redeeming shareholders. 

   SECTION 3. Purchase of Shares from each Fund. 

   (a) The Distributor shall have the right to buy from each Fund the Shares 
needed, but not more than the Shares needed (except for clerical errors in 
transmission), to fill unconditional orders for Shares placed with the 
Distributor by investors or securities dealers. The price which the 
Distributor shall pay for the Shares so purchased from the Fund shall be the 
net asset value, determined as set forth in the Prospectus, used in 
determining the public offering price on which such orders were based. 

   (b) The Shares are to be resold by the Distributor at the public offering 
price of Shares as set forth in the Prospectus, to investors or to securities 
dealers, including DWR, who have entered into selected dealer agreements with 
the Distributor upon the terms and conditions set forth in Section 7 hereof 
("Selected Dealers"). 

   (c) Each Fund shall have the right to suspend the sale of the Shares at 
times when redemption is suspended pursuant to the conditions set forth in 
Section 4(f) hereof. Each Fund shall also have the right 

                                1           
<PAGE>
to suspend the sale of the Shares if trading on the New York Stock Exchange 
shall have been suspended, if a banking moratorium shall have been declared 
by federal or New York authorities, or if there shall have been some other 
extraordinary event which, in the judgment of a Fund, makes it impracticable 
to sell its Shares. 

   (d) Each Fund, or any agent of a Fund designated in writing by the Fund, 
shall be promptly advised of all purchase orders for Shares received by the 
Distributor. Any order may be rejected by a Fund; provided, however, that a 
Fund will not arbitrarily or without reasonable cause refuse to accept orders 
for the purchase of Shares. The Distributor will confirm orders upon their 
receipt, and each Fund (or its agent) upon receipt of payment therefor and 
instructions will deliver share certificates for such Shares or a statement 
confirming the issuance of Shares. Payment shall be made to the Fund in New 
York Clearing House funds. The Distributor agrees to cause such payment and 
such instructions to be delivered promptly to the Fund (or its agent). 

   (e) With respect to Shares sold by any Selected Dealer, the Distributor is 
authorized to direct each Fund's transfer agent to receive instructions 
directly from the Selected Dealer on behalf of the Distributor as to 
registration of Shares in the names of investors and to confirm issuance of 
the Shares to such investors. The Distributor is also authorized to instruct 
the transfer agent to receive payment directly from the Selected Dealer on 
behalf of the Distributor, for prompt transmittal to each Fund's custodian, 
of the purchase price of the Shares. In such event the Distributor shall 
obtain from the Selected Dealer and maintain a record of such registration 
instructions and payments. 

   SECTION 4. Repurchase or Redemption of Shares. 

   (a) Any of the outstanding Shares of a Fund may be tendered for redemption 
at any time, and each Fund agrees to redeem its Shares so tendered in 
accordance with the applicable provisions set forth in its Prospectus. The 
price to be paid to redeem the Shares shall be equal to the net asset value 
determined as set forth in the Prospectus less, in the case of a Fund whose 
Shares are offered with a contingent deferred sales charge ("CDSC"), any 
applicable CDSC. Upon any redemption of Shares the Fund shall pay the total 
amount of the redemption price in New York Clearing House funds in accordance 
with applicable provisions of the Prospectus. 

   (b) In the case of a Fund whose Shares are offered with a front-end sales 
charge, the redemption by a Fund of any of its Shares purchased by or through 
the Distributor will not affect the applicable front-end sales charge secured 
by the Distributor or any Selected Dealer in the course of the original sale, 
except that if any Shares are tendered for redemption within seven business 
days after the date of the confirmation of the original purchase, the right 
to the applicable front-end sales charge shall be forfeited by the 
Distributor and the Selected Dealer which sold such Shares. 

   (c) In the case of a Fund whose Shares are offered with a CDSC, the 
proceeds of any redemption of Shares shall be paid by each Fund as follows: 
(i) any applicable CDSC shall be paid to the Distributor or to the Selected 
Dealer, or, when applicable, pursuant to the Rules of the Association of the 
National Association of Securities Dealers, Inc. ("NASD"), retained by the 
Fund and (ii) the balance shall be paid to the redeeming shareholders, in 
each case in accordance with applicable provisions of its Prospectus in New 
York Clearing House funds. The Distributor is authorized to direct a Fund to 
pay directly to the Selected Dealer any CDSC payable by a Fund to the 
Distributor in respect of Shares sold by the Selected Dealer to the redeeming 
shareholders. 

   (d) The Distributor is authorized, as agent for the Fund, to repurchase 
Shares, represented by a share certificate which is delivered to any office 
of the Distributor in accordance with applicable provisions set forth in each 
Fund's Prospectus. The Distributor shall promptly transmit to the transfer 
agent of the Fund for redemption all Shares so delivered. The Distributor 
shall be responsible for the accuracy of instructions transmitted to the 
Fund's transfer agent in connection with all such repurchases. 

   (e) The Distributor is authorized, as agent for each Fund, to repurchase 
Shares held in a shareholder's account with a Fund for which no share 
certificate has been issued, upon the telephonic request of the shareholders, 
or at the discretion of the Distributor. The Distributor shall promptly 
transmit to the 

                                2           
<PAGE>
transfer agent of the Fund, for redemption, all such orders for repurchase of 
Shares. Payment for Shares repurchased may be made by a Fund to the 
Distributor for the account of the shareholder. The Distributor shall be 
responsible for the accuracy of instructions transmitted to the Fund's 
transfer agent in connection with all such repurchases. 

   (f) Redemption of its Shares or payment by a Fund may be suspended at 
times when the New York Stock Exchange is closed, when trading on said 
Exchange is restricted, when an emergency exists as a result of which 
disposal by a Fund of securities owned by it is not reasonably practicable or 
it is not reasonably practicable for a Fund fairly to determine the value of 
its net assets, or during any other period when the SEC, by order, so 
permits. 

   (g) With respect to its Shares tendered for redemption or repurchase by 
any Selected Dealer on behalf of its customers, the Distributor is authorized 
to instruct the transfer agent of a Fund to accept orders for redemption or 
repurchase directly from the Selected Dealer on behalf of the Distributor and 
to instruct the Fund to transmit payments for such redemptions and 
repurchases directly to the Selected Dealer on behalf of the Distributor for 
the account of the shareholder. The Distributor shall obtain from the 
Selected Dealer, and shall maintain, a record of such orders. The Distributor 
is further authorized to obtain from the Fund, and shall maintain, a record 
of payment made directly to the Selected Dealer on behalf of the Distributor. 

   SECTION 5. Duties of the Fund. 

   (a) Each Fund shall furnish to the Distributor copies of all information, 
financial statements and other papers which the Distributor may reasonably 
request for use in connection with the distribution of its Shares, including 
one certified copy, upon request by the Distributor, of all financial 
statements prepared by the Fund and examined by independent accountants. Each 
Fund shall, at the expense of the Distributor, make available to the 
Distributor such number of copies of its Prospectus as the Distributor shall 
reasonably request. 

   (b) Each Fund shall take, from time to time, but subject to the necessary 
approval of its shareholders, all necessary action to fix the number of its 
authorized Shares and to register Shares under the 1933 Act, to the end that 
there will be available for sale such number of Shares as investors may 
reasonably be expected to purchase. 

   (c) Each Fund shall use its best efforts to pay the filing fees for an 
appropriate number of its Shares to be sold under the securities laws of such 
states as the Distributor and the Fund may approve. Any qualification to sell 
its Shares in a state may be withheld, terminated or withdrawn by a Fund at 
any time in its discretion. As provided in Section 8(c) hereof, such filing 
fees shall be paid by the Fund. The Distributor shall furnish any information 
and other material relating to its affairs and activities as may be required 
by a Fund in connection with the sale of its Shares in any state. 

   (d) Each Fund shall, at the expense of the Distributor, furnish, in 
reasonable quantities upon request by the Distributor, copies of its annual 
and interim reports. 

   SECTION 6. Duties of the Distributor. 

   (a) The Distributor shall sell shares of each Fund through DWR and may 
sell shares through other securities dealers and its own Account Executives, 
and shall devote reasonable time and effort to promote sales of the Shares, 
but shall not be obligated to sell any specific number of Shares. The 
services of the Distributor hereunder are not exclusive and it is understood 
that the Distributor may act as principal underwriter for other registered 
investment companies, so long as the performance of its obligations hereunder 
is not impaired thereby. It is also understood that Selected Dealers, 
including DWR, may also sell shares for other registered investment 
companies. 

   (b) Neither the Distributor nor any Selected Dealer shall give any 
information or make any representations, other than those contained in the 
Registration Statement or related Prospectus and any sales literature 
specifically approved by the appropriate Fund. 

   (c) The Distributor agrees that it will at all times comply with the 
applicable terms and limitations of the Rules of the Association of the NASD. 

                                3           
<PAGE>
   SECTION 7. Selected Dealers Agreements. 

   (a) The Distributor shall have the right to enter into selected dealer 
agreements with Selected Dealers for the sale of Shares. In making agreements 
with Selected Dealers, the Distributor shall act only as principal and not as 
agent for a Fund. Shares sold to Selected Dealers shall be for resale by such 
dealers only at the public offering price set forth in the Prospectus. With 
respect to Funds whose Shares are offered with a front-end sales charge, in 
such agreement the Distributor shall have the right to fix the portion of the 
applicable front-end sales charge which may be allocated to the Selected 
Dealers. 

   (b) Within the United States, the Distributor shall offer and sell Shares 
only to Selected Dealers that are members in good standing of the NASD. 

   (c) The Distributor shall adopt and follow procedures, as approved by each 
Fund, for the confirmation of sales of its Shares to investors and Selected 
Dealers, the collection of amounts payable by investors and Selected Dealers 
on such sales, and the cancellation of unsettled transactions, as may be 
necessary to comply with the requirements of the NASD, as such requirements 
may from time to time exist. 

   SECTION 8. Payment of Expenses. 

   (a) Each Fund shall bear all costs and expenses of the Fund, including 
fees and disbursements of legal counsel including counsel to the 
Directors/Trustees of each Fund who are not interested persons (as defined in 
the 1940 Act) of the Fund or the Distributor, and independent accountants, in 
connection with the preparation and filing of any required Registration 
Statements and Prospectuses and all amendments and supplements thereto, and 
the expense of preparing, printing, mailing and otherwise distributing 
prospectuses and statements of additional information, annual or interim 
reports or proxy materials to shareholders. 

   (b) The Distributor shall bear all expenses incurred by it in connection 
with its duties and activities under this Agreement including the payment to 
Selected Dealers of any sales commissions, service fees and other expenses 
for sales of a Fund's Shares (except such expenses as are specifically 
undertaken herein by a Fund) incurred or paid by Selected Dealers, including 
DWR. The Distributor shall bear the costs and expenses of preparing, printing 
and distributing any supplementary sales literature used by the Distributor 
or furnished by it for use by Selected Dealers in connection with the 
offering of the Shares for sale. Any expenses of advertising incurred in 
connection with such offering will also be the obligation of the Distributor. 
It is understood and agreed that, so long as a Fund's Plan of Distribution 
pursuant to Rule 12b-1 under the 1940 Act ("Rule 12b-1 Plan") continues in 
effect, any expenses incurred by the Distributor hereunder may be paid in 
accordance with the terms of such Rule 12b-1 Plan. 

   (c) Each Fund shall pay the filing fees, and, if necessary or advisable in 
connection therewith, bear the cost and expense of qualifying each Fund as a 
broker or dealer, in such states of the United States or other jurisdictions 
as shall be selected by the Fund and the Distributor pursuant to Section 5(c) 
hereof and the cost and expenses payable to each such state for continuing to 
offer Shares therein until the Fund decides to discontinue selling Shares 
pursuant to Section 5(c) hereof. 

   SECTION 9. Indemnification. 

   (a) Each Fund shall indemnify and hold harmless the Distributor and each 
person, if any, who controls the Distributor against any loss, liability, 
claim, damage or expense (including the reasonable cost of investigating or 
defending any alleged loss, liability, claim, damage or expense and 
reasonable counsel fees incurred in connection therewith) arising by reason 
of any person acquiring any Shares, which may be based upon the 1933 Act, or 
on any other statute or at common law, on the ground that the Registration 
Statement or related Prospectus and Statement of Additional Information, as 
from time to time amended and supplemented, or the annual or interim reports 
to shareholders of a Fund, includes an untrue statement of a material fact or 
omits to state a material fact required to be stated therein or necessary in 
order to make the statements therein not misleading, unless such statement or 
omission was made in reliance upon, and in conformity with, information 
furnished to the Fund in connection therewith by or on behalf of the 
Distributor; provided, however, that in no case (i) is the indemnity of a 
Fund in 

                                4           
<PAGE>
favor of the Distributor and any such controlling persons to be deemed to 
protect the Distributor or any such controlling persons thereof against any 
liability to a Fund or its security holders to which the Distributor or any 
such controlling persons would otherwise be subject by reason of willful 
misfeasance, bad faith or gross negligence in the performance of its duties 
or by reason of reckless disregard of its obligations and duties under this 
Agreement; or (ii) is a Fund to be liable under its indemnity agreement 
contained in this paragraph with respect to any claim made against the 
Distributor or any such controlling persons, unless the Distributor or any 
such controlling persons, as the case may be, shall have notified the Fund in 
writing within a reasonable time after the summons or other first legal 
process giving information of the nature of the claim shall have been served 
upon the Distributor or such controlling persons (or after the Distributor or 
such controlling persons shall have received notice of such service on any 
designated agent), but failure to notify the Fund of any such claim shall not 
relieve it from any liability which it may have to the person against whom 
such action is brought otherwise than on account of its indemnity agreement 
contained in this paragraph. Each Fund will be entitled to participate at its 
own expense in the defense, or, if it so elects, to assume the defense, of 
any such suit brought to enforce any such liability, but if a Fund elects to 
assume the defense, such defense shall be conducted by counsel chosen by it 
and satisfactory to the Distributor or such controlling person or persons, 
defendant or defendants in the suit. In the event the Fund elects to assume 
the defense of any such suit and retain such counsel, the Distributor or such 
controlling person or persons, defendant or defendants in the suit, shall 
bear the fees and expenses of any additional counsel retained by them, but, 
in case the Fund does not elect to assume the defense of any such suit, it 
will reimburse the Distributor or such controlling person or persons, 
defendant or defendants in the suit, for the reasonable fees and expenses of 
any counsel retained by them. Each Fund shall promptly notify the Distributor 
of the commencement of any litigation or proceedings against it or any of its 
officers or Directors/Trustees in connection with the issuance or sale of the 
Shares. 

   (b)   (i) The Distributor shall indemnify and hold harmless each Fund and 
each of its Directors/ Trustees and officers and each person, if any, who 
controls the Fund against any loss, liability, claim, damage, or expense 
described in the indemnity contained in subsection (a) of this Section, but 
only with respect to statements or omissions made in reliance upon, and in 
conformity with, information furnished to a Fund in writing by or on behalf 
of the Distributor for use in connection with the Registration Statement or 
related Prospectus and Statement of Additional Information, as from time to 
time amended, or the annual or interim reports to shareholders. 

        (ii) The Distributor shall indemnify and hold harmless each Fund and 
each Fund's transfer agent, individually and in its capacity as the Fund's 
transfer agent, from and against any claims, damages and liabilities which 
arise as a result of actions taken pursuant to instructions from, or on 
behalf of, the Distributor to: (1) redeem all or a part of shareholder 
accounts in the Fund pursuant to Section 4(g) hereof and pay the proceeds to, 
or as directed by, the Distributor for the account of each shareholder whose 
Shares are so redeemed; and (2) register Shares in the names of investors, 
confirm the issuance thereof and receive payment therefor pursuant to Section 
3(e) hereof. 

       (iii) In case any action shall be brought against a Fund or any person 
so indemnified by this Section 9(b) in respect of which indemnity may be 
sought against the Distributor, the Distributor shall have the rights and 
duties given to a Fund, and the Fund and each person so indemnified shall 
have the rights and duties given to the Distributor, by the provisions of 
subsection (a) of this Section 9. 

   (c) If the indemnification provided for in this Section 9 is unavailable 
or insufficient to hold harmless an indemnified party under subsection (a) or 
(b) above in respect of any losses, claims, damages, liabilities or expenses 
(or actions in respect thereof) referred to herein, then each indemnifiying 
party shall contribute to the amount paid or payable by such indemnified 
party as a result of such losses, claims, damages, liabilities or expenses 
(or actions in respect thereof) in such proportion as is appropriate to 
reflect the relative benefits received by a Fund on the one hand and the 
Distributor on the other from the offering of the Shares. If, however, the 
allocation provided by the immediately preceding sentence is not permitted by 
applicable law, then each indemnifying party shall contribute to such amount 
paid or payable by such indemnified party in such proportion as is 
appropriate to reflect not only such relative benefits but also the relative 
fault of a Fund on the one hand and the Distributor on the other in 
connection with the statements or omissions which resulted in such losses, 
claims, damages, liabilities or expenses (or actions 

                                5           
<PAGE>
in respect thereof), as well as any other relevant equitable considerations. 
The relative benefits received by a Fund on the one hand and the Distributor 
on the other shall be deemed to be in the same proportion as the total net 
proceeds from the offering (before deducting expenses) received by the Fund 
bear to the total compensation received by the Distributor, in each case as 
set forth in the Prospectus. The relative fault shall be determined by 
reference to, among other things, whether the untrue or alleged untrue 
statement of a material fact or the omission or alleged omission to state a 
material fact relates to information supplied by a Fund or the Distributor 
and the parties' relative intent, knowledge, access to information and 
opportunity to correct or prevent such statement or omission. Each Fund and 
the Distributor agree that it would not be just and equitable if contribution 
were determined by pro rata allocation or by any other method of allocation 
which does not take into account the equitable considerations referred to 
above. The amount paid or payable by an indemnified party as a result of the 
losses, claims, damages, liabilities or expenses (or actions in respect 
thereof) referred to above shall be deemed to include any legal or other 
expenses reasonably incurred by such indemnified party in connection with 
investigating or defending any such claim. Notwithstanding the provisions of 
this subsection (c), the Distributor shall not be required to contribute any 
amount in excess of the amount by which the total price at which the Shares 
distributed by it to the public were offered to the public exceeds the amount 
of any damages which it has otherwise been required to pay by reason of such 
untrue or alleged untrue statement or omission or alleged omission. No person 
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) 
of the 1933 Act) shall be entitled to contribution from any person who was 
not guilty of such fraudulent misrepresentation. 

   SECTION 10. Duration and Termination of this Agreement. This Agreement 
shall become effective with respect to a Fund as of the date first above 
written and shall remain in force until April 30, 1998, and thereafter, but 
only so long as such continuance is specifically approved at least annually 
by (i) the Board of Directors/Trustees of each Fund, or by the vote of a 
majority of the outstanding voting securities of the Fund, cast in person or 
by proxy, and (ii) a majority of those Directors/Trustees who are not parties 
to this Agreement or interested persons of any such party and who have no 
direct or indirect financial interest in this Agreement or in the operation 
of the Fund's Rule 12b-1 Plan or in any agreement related thereto, cast in 
person at a meeting called for the purpose of voting upon such approval. 

   This Agreement may be terminated at any time without the payment of any 
penalty, by the Directors/Trustees of a Fund, by a majority of the 
Directors/Trustees of a Fund who are not interested persons of the Fund and 
who have no direct or indirect financial interest in this Agreement, or by 
vote of a majority of the outstanding voting securities of a Fund, or by the 
Distributor, on sixty days' written notice to the other party. This Agreement 
shall automatically terminate in the event of its assignment. 

   The terms "vote of a majority of the outstanding voting securities," 
"assignment" and "interested person," when used in this Agreement, shall have 
the respective meanings specified in the 1940 Act. 

   SECTION 11. Amendments of this Agreement. This Agreement may be amended by 
the parties only if such amendment is specifically approved by (i) the 
Directors/Trustees of a Fund, or by the vote of a majority of outstanding 
voting securities of a Fund, and (ii) a majority of those Directors/Trustees 
of a Fund who are not parties to this Agreement or interested persons of any 
such party and who have no direct or indirect financial interest in this 
Agreement or in any Agreement related to the Fund's Rule 12b-1 Plan, cast in 
person at a meeting called for the purpose of voting on such approval. 

   SECTION 12. Additional Funds. If at any time another Fund desires to 
appoint the Distributor as its principal underwriter and distributor under 
this Agreement, it shall notify the Distributor in writing. If the 
Distributor is willing to serve as the Fund's principal underwriter and 
distributor under this Agreement, it shall notify the Fund in writing, 
whereupon such other Fund shall become a Fund hereunder. 

   SECTION 13. Governing Law. This Agreement shall be construed in accordance 
with the law of the State of New York and the applicable provisions of the 
1940 Act. To the extent the applicable law of the State of New York, or any 
of the provisions herein, conflicts with the applicable provisions of the 
1940 Act, the latter shall control.

   SECTION 14. Personal Liability. With respect to any Fund that is organized

under the Declaration collectively as Trustees, but not as individuals or 
personally; and no Trustee, shareholder, officer, employee or agent of any 
Fund shall be held to any personal liability, nor shall resort be had to 
their private property for the satisfaction of any obligation or claim or 
otherwise, in connection with the affairs of any Fund, but the Trust Estate 
only shall be liable. 

   IN WITNESS WHEREOF, the parties hereto have executed and delivered this 
Agreement as of the day and year first written in New York, New York.

                              DEAN WITTER FUNDS 

                            DISTRIBUTION AGREEMENT 

   AGREEMENT made as of this 28th day of July, 1997 between each of the 
open-end investment companies to which Dean Witter InterCapital Inc. acts as 
investment manager, that are listed on Schedule A, as may be amended from 
time to time (each, a "Fund" and collectively, the "Funds"), and Dean Witter 
Distributors Inc., a Delaware corporation (the "Distributor"). 

                             W I T N E S S E T H: 

   WHEREAS, each Fund is registered as an open-end investment company under 
the Investment Company Act of 1940, as amended (the "1940 Act"), and it is in 
the interest of each Fund to offer its shares for sale continuously, and 

   WHEREAS, each Fund and the Distributor wish to enter into an agreement 
with each other with respect to the continuous offering of each Fund's 
transferable shares, of $0.01 par value (the "Shares"), to commence on the 
date listed above, in order to promote the growth of each Fund and facilitate 
the distribution of its shares. 

   NOW, THEREFORE, the parties agree as follows: 

   SECTION 1. Appointment of the Distributor. 

   (a) Each Fund hereby appoints the Distributor as the principal underwriter 
and distributor of the Fund to sell Shares to the public on the terms set 
forth in this Agreement and that Fund's prospectus and the Distributor hereby 
accepts such appointment and agrees to act hereunder. Each Fund, during the 
term of this Agreement, shall sell Shares to the Distributor upon the terms 
and conditions set forth herein. 

   (b) The Distributor agrees to purchase Shares, as principal for its own 
account, from each Fund and to sell Shares as principal to investors, and 
securities dealers, including Dean Witter Reynolds Inc. ("DWR"), an affiliate 
of the Distributor, upon the terms described herein and in that Fund's 
prospectus (the "Prospectus") and statement of additional information 
included in the Fund's registration statement (the "Registration Statement") 
most recently filed from time to time with the Securities and Exchange 
Commission (the "SEC") and effective under the Securities Act of 1933, as 
amended (the "1933 Act"), and the 1940 Act or as the Prospectus may be 
otherwise amended or supplemented and filed with the SEC pursuant to Rule 497 
under the 1933 Act. 

   SECTION 2 Exclusive Nature of Duties. The Distributor shall be the 
exclusive principal underwriter and distributor of each Fund, except that the 
exclusive rights granted to the Distributor to sell the Shares shall not 
apply to Shares issued by each Fund: (i) in connection with the merger or 
consolidation of any other investment company or personal holding company 
with the Fund or the acquisition by purchase or otherwise of all (or 
substantially all) the assets or the outstanding shares of any such company 
by the Fund; (ii) pursuant to reinvestment of dividends or capital gains 
distributions; or (iii) pursuant to the reinstatement privilege afforded 
redeeming shareholders. 

   SECTION 3. Purchase of Shares from each Fund. The Shares are offered in 
four classes (each, a "Class"), as described in the Prospectus, as amended or 
supplemented from time to time. 

   (a) The Distributor shall have the right to buy from each Fund the Shares 
of the particular class needed, but not more than the Shares needed (except 
for clerical errors in transmission), to fill unconditional orders for Shares 
of the applicable class placed with the Distributor by investors or 
securities dealers. The price which the Distributor shall pay for the Shares 
so purchased from the Fund shall be the net asset value, determined as set 
forth in the Prospectus, used in determining the public offering price on 
which such orders were based. 

   (b) The Shares are to be resold by the Distributor at the public offering 
price of Shares of the applicable class as set forth in the Prospectus, to 
investors or to securities dealers, including DWR, who have entered into 
selected dealer agreements with the Distributor upon the terms and conditions 
set forth in Section 7 hereof ("Selected Dealers"). 

                                1           
<PAGE>
   (c) Each Fund shall have the right to suspend the sale of the Shares at 
times when redemption is suspended pursuant to the conditions set forth in 
Section 4(f) hereof. Each Fund shall also have the right to suspend the sale 
of the Shares if trading on the New York Stock Exchange shall have been 
suspended, if a banking moratorium shall have been declared by federal or New 
York authorities, or if there shall have been some other extraordinary event 
which, in the judgment of a Fund, makes it impracticable to sell its Shares. 

   (d) Each Fund, or any agent of a Fund designated in writing by the Fund, 
shall be promptly advised of all purchase orders for Shares received by the 
Distributor. Any order may be rejected by a Fund; provided, however, that a 
Fund will not arbitrarily or without reasonable cause refuse to accept orders 
for the purchase of Shares. The Distributor will confirm orders upon their 
receipt, and each Fund (or its agent) upon receipt of payment therefor and 
instructions will deliver share certificates for such Shares or a statement 
confirming the issuance of Shares. Payment shall be made to the Fund in New 
York Clearing House funds. The Distributor agrees to cause such payment and 
such instructions to be delivered promptly to the Fund (or its agent). 

   (e) With respect to Shares sold by any Selected Dealer, the Distributor is 
authorized to direct each Fund's transfer agent to receive instructions 
directly from the Selected Dealer on behalf of the Distributor as to 
registration of Shares in the names of investors and to confirm issuance of 
the Shares to such investors. The Distributor is also authorized to instruct 
the transfer agent to receive payment directly from the Selected Dealer on 
behalf of the Distributor, for prompt transmittal to each Fund's custodian, 
of the purchase price of the Shares. In such event the Distributor shall 
obtain from the Selected Dealer and maintain a record of such registration 
instructions and payments. 

   SECTION 4. Repurchase or Redemption of Shares. 

   (a) Any of the outstanding Shares of a Fund may be tendered for redemption 
at any time, and each Fund agrees to redeem its Shares so tendered in 
accordance with the applicable provisions set forth in its Prospectus. The 
price to be paid to redeem the Shares shall be equal to the net asset value 
determined as set forth in the Prospectus less any applicable contingent 
deferred sales charge ("CDSC"). Upon any redemption of Shares the Fund shall 
pay the total amount of the redemption price in New York Clearing House funds 
in accordance with applicable provisions of the Prospectus. 

   (b) The redemption by a Fund of any of its Class A Shares purchased by or 
through the Distributor will not affect the applicable front-end sales charge 
secured by the Distributor or any Selected Dealer in the course of the 
original sale, except that if any Class A Shares are tendered for redemption 
within seven business days after the date of the confirmation of the original 
purchase, the right to the applicable front-end sales charge shall be 
forfeited by the Distributor and the Selected Dealer which sold such Shares. 

   (c) The proceeds of any redemption of Class A, Class B or Class C Shares 
shall be paid by each Fund as follows: (i) any applicable CDSC shall be paid 
to the Distributor or to the Selected Dealer, or, when applicable, pursuant 
to the Rules of the Association of the National Association of Securities 
Dealers, Inc. ("NASD"), retained by the Fund and (ii) the balance shall be 
paid to the redeeming shareholders, in each case in accordance with 
applicable provisions of its Prospectus in New York Clearing House funds. The 
Distributor is authorized to direct a Fund to pay directly to the Selected 
Dealer any CDSC payable by a Fund to the Distributor in respect of Class A, 
Class B, or Class C Shares sold by the Selected Dealer to the redeeming 
shareholders. 

   (d) The Distributor is authorized, as agent for the Fund, to repurchase 
Shares, represented by a share certificate which is delivered to any office 
of the Distributor in accordance with applicable provisions set forth in each 
Fund's Prospectus. The Distributor shall promptly transmit to the transfer 
agent of the Fund for redemption all Shares so delivered. The Distributor 
shall be responsible for the accuracy of instructions transmitted to the 
Fund's transfer agent in connection with all such repurchases. 

   (e) The Distributor is authorized, as agent for each Fund, to repurchase 
Shares held in a shareholder's account with a Fund for which no share 
certificate has been issued, upon the telephonic request of the shareholders, 
or at the discretion of the Distributor. The Distributor shall promptly 
transmit to the 

                                2           
<PAGE>
transfer agent of the Fund, for redemption, all such orders for repurchase of 
Shares. Payment for Shares repurchased may be made by a Fund to the 
Distributor for the account of the shareholder. The Distributor shall be 
responsible for the accuracy of instructions transmitted to the Fund's 
transfer agent in connection with all such repurchases. 

   (f) Redemption of its Shares or payment by a Fund may be suspended at 
times when the New York Stock Exchange is closed, when trading on said 
Exchange is restricted, when an emergency exists as a result of which 
disposal by a Fund of securities owned by it is not reasonably practicable or 
it is not reasonably practicable for a Fund fairly to determine the value of 
its net assets, or during any other period when the SEC, by order, so 
permits. 

   (g) With respect to its Shares tendered for redemption or repurchase by 
any Selected Dealer on behalf of its customers, the Distributor is authorized 
to instruct the transfer agent of a Fund to accept orders for redemption or 
repurchase directly from the Selected Dealer on behalf of the Distributor and 
to instruct the Fund to transmit payments for such redemptions and 
repurchases directly to the Selected Dealer on behalf of the Distributor for 
the account of the shareholder. The Distributor shall obtain from the 
Selected Dealer, and shall maintain, a record of such orders. The Distributor 
is further authorized to obtain from the Fund, and shall maintain, a record 
of payment made directly to the Selected Dealer on behalf of the Distributor. 

   SECTION 5. Duties of the Fund. 

   (a) Each Fund shall furnish to the Distributor copies of all information, 
financial statements and other papers which the Distributor may reasonably 
request for use in connection with the distribution of its Shares, including 
one certified copy, upon request by the Distributor, of all financial 
statements prepared by the Fund and examined by independent accountants. Each 
Fund shall, at the expense of the Distributor, make available to the 
Distributor such number of copies of its Prospectus as the Distributor shall 
reasonably request. 

   (b) Each Fund shall take, from time to time, but subject to the necessary 
approval of its shareholders, all necessary action to fix the number of its 
authorized Shares and to register Shares under the 1933 Act, to the end that 
there will be available for sale such number of Shares as investors may 
reasonably be expected to purchase. 

   (c) Each Fund shall use its best efforts to pay the filing fees for an 
appropriate number of its Shares to be sold under the securities laws of such 
states as the Distributor and the Fund may approve. Any qualification to sell 
its Shares in a state may be withheld, terminated or withdrawn by a Fund at 
any time in its discretion. As provided in Section 8(c) hereof, such filing 
fees shall be paid by the Fund. The Distributor shall furnish any information 
and other material relating to its affairs and activities as may be required 
by a Fund in connection with the sale of its Shares in any state. 

   (d) Each Fund shall, at the expense of the Distributor, furnish, in 
reasonable quantities upon request by the Distributor, copies of its annual 
and interim reports. 

   SECTION 6. Duties of the Distributor. 

   (a) The Distributor shall sell shares of each Fund through DWR and may 
sell shares through other securities dealers and its own Account Executives, 
and shall devote reasonable time and effort to promote sales of the Shares, 
but shall not be obligated to sell any specific number of Shares. The 
services of the Distributor hereunder are not exclusive and it is understood 
that the Distributor may act as principal underwriter for other registered 
investment companies, so long as the performance of its obligations hereunder 
is not impaired thereby. It is also understood that Selected Dealers, 
including DWR, may also sell shares for other registered investment 
companies. 

   (b) Neither the Distributor nor any Selected Dealer shall give any 
information or make any representations, other than those contained in the 
Registration Statement or related Prospectus and any sales literature 
specifically approved by the appropriate Fund. 

   (c) The Distributor agrees that it will at all times comply with the 
applicable terms and limitations of the Rules of the Association of the NASD. 

                                3           
<PAGE>
   SECTION 7. Selected Dealers Agreements. 

   (a) The Distributor shall have the right to enter into selected dealer 
agreements with Selected Dealers for the sale of Shares. In making agreements 
with Selected Dealers, the Distributor shall act only as principal and not as 
agent for a Fund. Shares sold to Selected Dealers shall be for resale by such 
dealers only at the public offering price set forth in the Prospectus. With 
respect to Class A Shares, in such agreement the Distributor shall have the 
right to fix the portion of the applicable front-end sales charge which may 
be allocated to the Selected Dealers. 

   (b) Within the United States, the Distributor shall offer and sell Shares 
only to Selected Dealers that are members in good standing of the NASD. 

   (c) The Distributor shall adopt and follow procedures, as approved by each 
Fund, for the confirmation of sales of its Shares to investors and Selected 
Dealers, the collection of amounts payable by investors and Selected Dealers 
on such sales, and the cancellation of unsettled transactions, as may be 
necessary to comply with the requirements of the NASD, as such requirements 
may from time to time exist. 

   SECTION 8. Payment of Expenses. 

   (a) Each Fund shall bear all costs and expenses of the Fund, including 
fees and disbursements of legal counsel including counsel to the 
Directors/Trustees of each Fund who are not interested persons (as defined in 
the 1940 Act) of the Fund or the Distributor, and independent accountants, in 
connection with the preparation and filing of any required Registration 
Statements and Prospectuses and all amendments and supplements thereto, and 
the expense of preparing, printing, mailing and otherwise distributing 
prospectuses and statements of additional information, annual or interim 
reports or proxy materials to shareholders. 

   (b) The Distributor shall bear all expenses incurred by it in connection 
with its duties and activities under this Agreement including the payment to 
Selected Dealers of any sales commissions, service fees and other expenses 
for sales of a Fund's Shares (except such expenses as are specifically 
undertaken herein by a Fund) incurred or paid by Selected Dealers, including 
DWR. The Distributor shall bear the costs and expenses of preparing, printing 
and distributing any supplementary sales literature used by the Distributor 
or furnished by it for use by Selected Dealers in connection with the 
offering of the Shares for sale. Any expenses of advertising incurred in 
connection with such offering will also be the obligation of the Distributor. 
It is understood and agreed that, so long as a Fund's Plan of Distribution 
pursuant to Rule 12b-1 under the 1940 Act ("Rule 12b-1 Plan") continues in 
effect, any expenses incurred by the Distributor hereunder may be paid in 
accordance with the terms of such Rule 12b-1 Plan. 

   (c) Each Fund shall pay the filing fees, and, if necessary or advisable in 
connection therewith, bear the cost and expense of qualifying each Fund as a 
broker or dealer, in such states of the United States or other jurisdictions 
as shall be selected by the Fund and the Distributor pursuant to Section 5(c) 
hereof and the cost and expenses payable to each such state for continuing to 
offer Shares therein until the Fund decides to discontinue selling Shares 
pursuant to Section 5(c) hereof. 

   SECTION 9. Indemnification. 

   (a) Each Fund shall indemnify and hold harmless the Distributor and each 
person, if any, who controls the Distributor against any loss, liability, 
claim, damage or expense (including the reasonable cost of investigating or 
defending any alleged loss, liability, claim, damage or expense and 
reasonable counsel fees incurred in connection therewith) arising by reason 
of any person acquiring any Shares, which may be based upon the 1933 Act, or 
on any other statute or at common law, on the ground that the Registration 
Statement or related Prospectus and Statement of Additional Information, as 
from time to time amended and supplemented, or the annual or interim reports 
to shareholders of a Fund, includes an untrue statement of a material fact or 
omits to state a material fact required to be stated therein or necessary in 
order to make the statements therein not misleading, unless such statement or 
omission was made in reliance upon, and in conformity with, information 
furnished to the Fund in connection therewith by or on behalf of the 
Distributor; provided, however, that in no case (i) is the indemnity of a 
Fund in 

                                4           
<PAGE>
favor of the Distributor and any such controlling persons to be deemed to 
protect the Distributor or any such controlling persons thereof against any 
liability to a Fund or its security holders to which the Distributor or any 
such controlling persons would otherwise be subject by reason of willful 
misfeasance, bad faith or gross negligence in the performance of its duties 
or by reason of reckless disregard of its obligations and duties under this 
Agreement; or (ii) is a Fund to be liable under its indemnity agreement 
contained in this paragraph with respect to any claim made against the 
Distributor or any such controlling persons, unless the Distributor or any 
such controlling persons, as the case may be, shall have notified the Fund in 
writing within a reasonable time after the summons or other first legal 
process giving information of the nature of the claim shall have been served 
upon the Distributor or such controlling persons (or after the Distributor or 
such controlling persons shall have received notice of such service on any 
designated agent), but failure to notify the Fund of any such claim shall not 
relieve it from any liability which it may have to the person against whom 
such action is brought otherwise than on account of its indemnity agreement 
contained in this paragraph. Each Fund will be entitled to participate at its 
own expense in the defense, or, if it so elects, to assume the defense, of 
any such suit brought to enforce any such liability, but if a Fund elects to 
assume the defense, such defense shall be conducted by counsel chosen by it 
and satisfactory to the Distributor or such controlling person or persons, 
defendant or defendants in the suit. In the event the Fund elects to assume 
the defense of any such suit and retain such counsel, the Distributor or such 
controlling person or persons, defendant or defendants in the suit, shall 
bear the fees and expenses of any additional counsel retained by them, but, 
in case the Fund does not elect to assume the defense of any such suit, it 
will reimburse the Distributor or such controlling person or persons, 
defendant or defendants in the suit, for the reasonable fees and expenses of 
any counsel retained by them. Each Fund shall promptly notify the Distributor 
of the commencement of any litigation or proceedings against it or any of its 
officers or Directors/Trustees in connection with the issuance or sale of the 
Shares. 

   (b)   (i) The Distributor shall indemnify and hold harmless each Fund and 
each of its Directors/ Trustees and officers and each person, if any, who 
controls the Fund against any loss, liability, claim, damage, or expense 
described in the indemnity contained in subsection (a) of this Section, but 
only with respect to statements or omissions made in reliance upon, and in 
conformity with, information furnished to a Fund in writing by or on behalf 
of the Distributor for use in connection with the Registration Statement or 
related Prospectus and Statement of Additional Information, as from time to 
time amended, or the annual or interim reports to shareholders. 

        (ii) The Distributor shall indemnify and hold harmless each Fund and 
each Fund's transfer agent, individually and in its capacity as the Fund's 
transfer agent, from and against any claims, damages and liabilities which 
arise as a result of actions taken pursuant to instructions from, or on 
behalf of, the Distributor to: (1) redeem all or a part of shareholder 
accounts in the Fund pursuant to Section 4(g) hereof and pay the proceeds to, 
or as directed by, the Distributor for the account of each shareholder whose 
Shares are so redeemed; and (2) register Shares in the names of investors, 
confirm the issuance thereof and receive payment therefor pursuant to Section 
3(e) hereof. 

       (iii) In case any action shall be brought against a Fund or any person 
so indemnified by this Section 9(b) in respect of which indemnity may be 
sought against the Distributor, the Distributor shall have the rights and 
duties given to a Fund, and the Fund and each person so indemnified shall 
have the rights and duties given to the Distributor, by the provisions of 
subsection (a) of this Section 9. 

   (c) If the indemnification provided for in this Section 9 is unavailable 
or insufficient to hold harmless an indemnified party under subsection (a) or 
(b) above in respect of any losses, claims, damages, liabilities or expenses 
(or actions in respect thereof) referred to herein, then each indemnifiying 
party shall contribute to the amount paid or payable by such indemnified 
party as a result of such losses, claims, damages, liabilities or expenses 
(or actions in respect thereof) in such proportion as is appropriate to 
reflect the relative benefits received by a Fund on the one hand and the 
Distributor on the other from the offering of the Shares. If, however, the 
allocation provided by the immediately preceding sentence is not permitted by 
applicable law, then each indemnifying party shall contribute to such amount 
paid or payable by such indemnified party in such proportion as is 
appropriate to reflect not only such relative benefits but also the relative 
fault of a Fund on the one hand and the Distributor on the other in 
connection with the statements or omissions which resulted in such losses, 
claims, damages, liabilities or expenses (or actions 

                                5           
<PAGE>
in respect thereof), as well as any other relevant equitable considerations. 
The relative benefits received by a Fund on the one hand and the Distributor 
on the other shall be deemed to be in the same proportion as the total net 
proceeds from the offering (before deducting expenses) received by the Fund 
bear to the total compensation received by the Distributor, in each case as 
set forth in the Prospectus. The relative fault shall be determined by 
reference to, among other things, whether the untrue or alleged untrue 
statement of a material fact or the omission or alleged omission to state a 
material fact relates to information supplied by a Fund or the Distributor 
and the parties' relative intent, knowledge, access to information and 
opportunity to correct or prevent such statement or omission. Each Fund and 
the Distributor agree that it would not be just and equitable if contribution 
were determined by pro rata allocation or by any other method of allocation 
which does not take into account the equitable considerations referred to 
above. The amount paid or payable by an indemnified party as a result of the 
losses, claims, damages, liabilities or expenses (or actions in respect 
thereof) referred to above shall be deemed to include any legal or other 
expenses reasonably incurred by such indemnified party in connection with 
investigating or defending any such claim. Notwithstanding the provisions of 
this subsection (c), the Distributor shall not be required to contribute any 
amount in excess of the amount by which the total price at which the Shares 
distributed by it to the public were offered to the public exceeds the amount 
of any damages which it has otherwise been required to pay by reason of such 
untrue or alleged untrue statement or omission or alleged omission. No person 
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) 
of the 1933 Act) shall be entitled to contribution from any person who was 
not guilty of such fraudulent misrepresentation. 

   SECTION 10. Duration and Termination of this Agreement. This Agreement 
shall become effective with respect to a Fund as of the date first above 
written and shall remain in force until April 30, 1998, and thereafter, but 
only so long as such continuance is specifically approved at least annually 
by (i) the Board of Directors/Trustees of each Fund, or by the vote of a 
majority of the outstanding voting securities of the Fund, cast in person or 
by proxy, and (ii) a majority of those Directors/Trustees who are not parties 
to this Agreement or interested persons of any such party and who have no 
direct or indirect financial interest in this Agreement or in the operation 
of the Fund's Rule 12b-1 Plan or in any agreement related thereto, cast in 
person at a meeting called for the purpose of voting upon such approval. 

   This Agreement may be terminated at any time without the payment of any 
penalty, by the Directors/Trustees of a Fund, by a majority of the 
Directors/Trustees of a Fund who are not interested persons of the Fund and 
who have no direct or indirect financial interest in this Agreement, or by 
vote of a majority of the outstanding voting securities of a Fund, or by the 
Distributor, on sixty days' written notice to the other party. This Agreement 
shall automatically terminate in the event of its assignment. 

   The terms "vote of a majority of the outstanding voting securities," 
"assignment" and "interested person," when used in this Agreement, shall have 
the respective meanings specified in the 1940 Act. 

   SECTION 11. Amendments of this Agreement. This Agreement may be amended by 
the parties only if such amendment is specifically approved by (i) the 
Directors/Trustees of a Fund, or by the vote of a majority of outstanding 
voting securities of a Fund, and (ii) a majority of those Directors/Trustees 
of a Fund who are not parties to this Agreement or interested persons of any 
such party and who have no direct or indirect financial interest in this 
Agreement or in any Agreement related to the Fund's Rule 12b-1 Plan, cast in 
person at a meeting called for the purpose of voting on such approval. 

   SECTION 12. Additional Funds. If at any time another Fund desires to 
appoint the Distributor as its principal underwriter and distributor under 
this Agreement, it shall notify the Distributor in writing. If the 
Distributor is willing to serve as the Fund's principal underwriter and 
distributor under this Agreement, it shall notify the Fund in writing, 
whereupon such other Fund shall become a Fund hereunder. 

   SECTION 13. Governing Law. This Agreement shall be construed in accordance 
with the law of the State of New York and the applicable provisions of the 
1940 Act. To the extent the applicable law of the State of New York, or any 
of the provisions herein, conflicts with the applicable provisions of the 
1940 Act, the latter shall control.

personally; and no Trustee, shareholder, officer, employee or agent of any 
Fund shall be held to any personal liability, nor shall resort be had to

only shall be liable.

Agreement as of the day and year first written in New York, New York.

       AMENDED AND RESTATED PLAN OF DISTRIBUTION PURSUANT TO RULE 12B-1 
                                      OF 
                DEAN WITTER DEVELOPING GROWTH SECURITIES TRUST 

   WHEREAS, Dean Witter Developing Growth Securities Trust (the "Fund") is 
engaged in business as an open-end management investment company and is 
registered as such under the Investment Company Act of 1940, as amended (the 
"Act"); and 

   WHEREAS, on October 26, 1995, the Fund most recently amended and restated 
a Plan of Distribution pursuant to Rule 12b-1 under the Act which had 
initially been adopted on March 1, 1983, and the Trustees then determined 
that there was a reasonable likelihood that adoption of the Plan of 
Distribution, as then amended and restated, would benefit the Fund and its 
shareholders; and 

   WHEREAS, the Trustees believe that continuation of said Plan of 
Distribution, as amended and restated herein, is reasonably likely to 
continue to benefit the Fund and its shareholders; and 

   WHEREAS, on March 1, 1983, the Fund and Dean Witter Reynolds Inc. ("DWR") 
entered into a Distribution Agreement pursuant to which the Fund employed DWR 
as distributor of the Fund's shares; and 

   WHEREAS, on January 4, 1993, the Fund and DWR substituted Dean Witter 
Distributors Inc. (the "Distributor") in the place of DWR as distributor of 
the Fund's shares; and 

   WHEREAS, the Fund, DWR and the Distributor intend that DWR will continue 
to promote the sale of Fund shares and provide personal services to Fund 
shareholders with respect to their holdings of Fund shares; and 

   WHEREAS, the Fund and the Distributor entered into a separate Distribution 
Agreement dated as of July 28, 1997 (which superseded a Distribution 
Agreement dated May 31, 1997, which Agreement in turn superseded an Agreement 
dated June 30, 1993), pursuant to which the Fund has employed the Distributor 
in such capacity during the continuous offering of shares of the Fund. 

   NOW, THEREFORE, the Fund hereby amends the Plan of Distribution previously 
adopted and amended and restated, and the Distributor hereby agrees to the 
terms of said Plan of Distribution (the "Plan"), as amended herein, in 
accordance with Rule 12b-1 under the Act on the following terms and 
conditions with respect to the Class A, Class B and Class C shares of the 
Fund: 

   1(a)(i). With respect to Class A and Class C shares of the Fund, the 
Distributor hereby undertakes to directly bear all costs of rendering the 
services to be performed by it under this Plan and under the Distribution 
Agreement, except for those specific expenses that the Trustees determine to 
reimburse as hereinafter set forth. 

   1(a)(ii). The Fund is hereby authorized to reimburse the Distributor, DWR, 
its affiliates and other broker-dealers for distribution expenses incurred by 
them specifically on behalf of Class A and Class C shares of the Fund. 
Reimbursement will be made through payments at the end of each month. The 
amount of each monthly payment may in no event exceed an amount equal to a 
payment at the annual rate of 0.25%, in the case of Class A, and 1.0%, in the 
case of Class C, of the average net assets of the respective Class during the 
month. With respect to Class A, in the case of all expenses other than 
expenses representing the service fee and, with respect to Class C, in the 
case of all expenses other than expenses representing a gross sales credit or 
a residual to account executives, such amounts shall be determined at the 
beginning of each calendar quarter by the Trustees, including a majority of 
the Trustees who are not "interested persons" of the Fund, as defined in the 
Act. Expenses representing the service fee (for Class A) or a gross sales 
credit or a residual to account executives (for Class C) may be reimbursed 
without prior determination. In the event that the Distributor proposes that 
monies shall be reimbursed for other than such expenses, then in making the 
quarterly determinations of the amounts that may be expended by the Fund, the 
Distributor shall provide, and the Trustees shall review, a quarterly budget 
of projected distribution expenses to be incurred by the Distributor, DWR, 
its affiliates or other broker-dealers on behalf of the Fund together with a 
report explaining the purposes and anticipated benefits of incurring 


<PAGE>
such expenses. The Trustees shall determine the particular expenses, and the 
portion thereof that may be borne by the Fund, and in making such 
determination shall consider the scope of the Distributor's commitment to 
promoting the distribution of the Fund's Class A and Class C shares directly 
or through DWR, its affiliates or other broker-dealers. 

   1(a)(iii). If, as of the end of any calendar year, the actual expenses 
incurred by the Distributor, DWR, its affiliates and other broker-dealers on 
behalf of Class A or Class C shares of the Fund (including accrued expenses 
and amounts reserved for incentive compensation and bonuses) are less than 
the amount of payments made by such Class pursuant to this Plan, the 
Distributor shall promptly make appropriate reimbursement to the appropriate 
Class. If, however, as of the end of any calendar year, the actual expenses 
(other than expenses representing a gross sales credit) of the Distributor, 
DWR, its affiliates and other broker-dealers are greater than the amount of 
payments made by Class A or Class C shares of the Fund pursuant to this Plan, 
such Class will not reimburse the Distributor, DWR, its affiliates or other 
broker-dealers for such expenses through payments accrued pursuant to this 
Plan in the subsequent fiscal year. Expenses representing a gross sales 
credit may be reimbursed in the subsequent calendar year. 

   1(b). With respect to Class B shares of the Fund, the Fund shall pay to 
the Distributor, as the distributor of securities of which the Fund is the 
issuer, compensation for distribution of its Class B shares at the rate of 
the lesser of (i) 1.0% per annum of the average daily aggregate sales of the 
Fund's Class B shares since the Fund's inception (not including reinvestment 
of dividends and capital gains distributions from the Fund) less the average 
daily aggregate net asset value of the Fund's Class B shares redeemed since 
the Fund's inception upon which a contingent deferred sales charge has been 
imposed or upon which such charge has been waived, or (ii) 1.0% per annum of 
the average daily net assets of Class B. Such compensation shall be 
calculated and accrued daily and paid monthly or at such other intervals as 
the Trustees shall determine. 

   The Distributor may direct that all or any part of the amounts receivable 
by it under this Plan be paid directly to DWR, its affiliates or other 
broker-dealers who provide distribution and shareholder services. All 
payments made hereunder pursuant to the Plan shall be in accordance with the 
terms and limitations of the Rules of the Association of the National 
Association of Securities Dealers, Inc. 

   2. With respect to expenses incurred by each Class, the amount set forth 
in paragraph 1 of this Plan shall be paid for services of the Distributor, 
DWR its affiliates and other broker-dealers it may select in connection with 
the distribution of the Fund's shares, including personal services to 
shareholders with respect to their holdings of Fund shares, and may be spend 
by the Distributor, DWR, its affiliates and such broker-dealers on any 
activities or expenses related to the distribution of the Fund's shares or 
services to shareholders, including, but not limited to: compensation to, and 
expenses of, account executives or other employees of the Distributor, DWR, 
its affiliates or other broker-dealers; overhead and other branch office 
distribution-related expenses and telephone expenses of persons who engage in 
or support distribution of shares or who provide personal services to 
shareholders; printing of prospectuses and reports for other than existing 
shareholders; preparation, printing and distribution of sales literature and 
advertising materials and, with respect to Class B, opportunity costs in 
incurring the foregoing expenses (which may be calculated as a carrying 
charge on the excess of the distribution expenses incurred by the 
Distributor, DWR, its affiliates or other broker-dealers over distribution 
revenues received by them, such excess being hereinafter referred to as 
"carryover expenses"). The overhead and other branch office 
distribution-related expenses referred to in this paragraph 2 may include: 
(a) the expenses operating the branch offices of the Distributor or other 
broker-dealers, including DWR, in connection with the sale of the Fund 
shares, including lease costs, the salaries and employee benefits of 
operations and sales support personnel, utility costs, communications costs 
and the costs of stationery and supplies; (b) the costs of client sales 
seminars; (c) travel expenses of mutual fund sales coordinators to promote 
the sale of Fund shares; and (d) other expenses relating to branch promotion 
of Fund sales. Payments may also be made with respect to distribution 
expenses incurred in connection with the distribution of shares, including 
personal services to shareholders with respect to holdings of such shares, of 
an investment company whose assets are acquired by the Fund in a tax-free 
reorganization, provided that, with respect to Class B, carryover expenses as 
a percentage of Fund assets will not be materially increased thereby. It is 

                                2           
<PAGE>
contemplated that, with respect to Class A shares, the entire fee set forth 
in paragraph 1(a) will be characterized as a service fee within the meaning 
of the National Association of Securities Dealers, Inc. guidelines and that, 
with respect to Class B and Class C shares, payments at the annual rate of 
0.25% will be so characterized. 

   3. This Plan, as amended and restated, shall not take effect with respect 
to any particular Class until it has been approved, together with any related 
agreements, by votes of a majority of the Board of Trustees of the Fund and 
of the Trustees who are not "interested persons" of the Fund (as defined in 
the Act) and have no direct financial interest in the operation of this Plan 
or any agreements related to it (the "Rule 12b-1 Trustees"), cast in person 
at a meeting (or meetings) called for the purpose of voting on this Plan and 
such related agreements. 

   4. This Plan shall continue in effect with respect to each Class until 
April 30, 1998, and from year to year thereafter, provided such continuance 
is specifically approved at least annually in the manner provided for 
approval of this Plan in paragraph 3 hereof. 

   5. The Distributor shall provide to the Trustees of the Fund and the 
Trustees shall review, at least quarterly, a written report of the amounts so 
expended and the purposes for which such expenditures were made. In this 
regard, the Trustees shall request the Distributor to specify such items of 
expenses as the Trustees deem appropriate. The Trustees shall consider such 
items as they deem relevant in making the determinations required by 
paragraph 4 hereof. 

   6. This Plan may be terminated at any time with respect to a Class by vote 
of a majority of the Rule 12b-1 Trustees, or by vote of a majority of the 
outstanding voting securities of the Fund. The Plan may remain in effect with 
the respect to a particular Class even if the Plan has been terminated in 
accordance with this paragraph 6 with respect to any other Class. In the 
event of any such termination or in the event of nonrenewal, the Fund shall 
have no obligation to pay expenses which have been incurred by the 
Distributor, DWR, its affiliates or other broker-dealers in excess of 
payments made by the Fund pursuant to this Plan. However, with respect to 
Class B, this shall not preclude consideration by the Trustees of the manner 
in which such excess expenses shall be treated. 

   7. This Plan may not be amended with respect to any Class to increase 
materially the amount each Class may spend for distribution provided in 
paragraph 1 hereof unless such amendment is approved by a vote of at least a 
majority (as defined in the Act) of the outstanding voting securities of that 
Class, and no material amendment to the Plan shall be made unless approved in 
the manner provided for approval in paragraph 3 hereof. Class B shares will 
have the right to vote on any material increase in the fee set forth in 
paragraph 1(a) above affecting Class A shares. 

   8. While this Plan is in effect, the selection and nomination of Trustees 
who are not interested persons (as defined in the Act) of the Fund shall be 
committed to the discretion of the Trustees who are not interested persons. 

   9. The Fund shall preserve copies of this Plan and any related agreements 
and all reports made pursuant to paragraph 5 hereof, for a period of not less 
than six years from the date of this Plan, any such agreement or any such 
report, as the case may be, the first two years in an easily accessible 
place. 

   10. The Declaration of Trust establishing Dean Witter Developing Growth 
Securities Trust, dated December 28, 1982, a copy of which, together with all 
amendments thereto (the "Declaration"), is on file in the office of the 
Secretary of the Commonwealth of Massachusetts, provides that the name Dean 
Witter Developing Growth Securities Trust refers to the Trustees under the 
Declaration collectively as Trustees but not as individuals or personally; 
and no Trustee, shareholder, officer, employee or agent of Dean Witter 
Developing Growth Securities Trust shall be held to any personal liability, 
nor shall resort be had to their private property for this satisfaction of 
any obligation or claim or otherwise, in connection with the affairs of said 
Dean Witter Developing Growth Securities Trust, but the Trust Estate only 
shall be liable. 

                                3

                             MULTIPLE CLASS PLAN 
                            PURSUANT TO RULE 18F-3 

   INTRODUCTION 

   This plan (the "Plan") is adopted pursuant to Rule 18f-3(d) of the 
Investment Company Act of 1940, as amended (the "1940 Act"), and will be 
effective as of July 28, 1997. The Plan relates to shares of the open-end 
investment companies to which Dean Witter InterCapital Inc. acts as 
investment manager, that are listed on Schedule A, as may be amended from 
time to time (each, a "Fund" and collectively, the "Funds"). The Funds are 
distributed pursuant to a system (the "Multiple Class System") in which each 
class of shares (each, a "Class" and collectively, the "Classes") of a Fund 
represents a pro rata interest in the same portfolio of investments of the 
Fund and differs only to the extent outlined below. 

I. DISTRIBUTION ARRANGEMENTS 

   One or more Classes of shares of the Funds are offered for purchase by 
investors with the sales load structures described below. In addition, 
pursuant to Rule 12b-1 under the 1940 Act, the Funds have each adopted a Plan 
of Distribution (the "12b-1 Plan") under which shares of certain Classes are 
subject to the service and/or distribution fees ("12b-1 fees") described 
below. 

   1. Class A Shares 

   Class A shares are offered with a front-end sales load ("FESL"). The 
schedule of sales charges applicable to a Fund and the circumstances under 
which the sales charges are subject to reduction are set forth in each Fund's 
current prospectus. As stated in each Fund's current prospectus, Class A 
shares may be purchased at net asset value (without a FESL): (i) in the case 
of certain large purchases of such shares; and (ii) by certain limited 
categories of investors, in each case, under the circumstances and conditions 
set forth in each Fund's current prospectus. Class A shares purchased at net 
asset value may be subject to a contingent deferred sales charge ("CDSC") on 
redemptions made within one year of purchase. Further information relating to 
the CDSC, including the manner in which it is calculated, is set forth in 
paragraph 6 below. Class A shares are also subject to payments under each 
Fund's 12b-1 Plan to reimburse Dean Witter Distributors Inc., Dean Witter 
Reynolds Inc. ("DWR"), its affiliates and other broker-dealers for 
distribution expenses incurred by them specifically on behalf of the Class, 
assessed at an annual rate of up to 0.25% of average daily net assets. The 
entire amount of the 12b-1 fee represents a service fee within the meaning of 
National Association of Securities Dealers, Inc. ("NASD") guidelines. 

   2. Class B Shares 

   Class B shares are offered without a FESL, but will in most cases be 
subject to a six-year declining CDSC which is calculated in the manner set 
forth in paragraph 6 below. Class B shares purchased by certain qualified 
employer-sponsored benefit plans are subject to a three-year declining CDSC 
which is calculated in the manner set forth in paragraph 6 below. The 
schedule of CDSC charges applicable to each Fund is set forth in each Fund's 
current prospectus. With the exception of certain of the Funds which have a 
different formula described below (Dean Witter American Value Fund, Dean 
Witter Natural Resource Development Securities Inc., Dean Witter Strategist 
Fund and Dean Witter Dividend Growth Securities 

                                1           
<PAGE>

Inc.) (1), Class B shares are also subject to a fee under each Fund's 
respective 12b-1 Plan, assessed at the annual rate of up to 1.0% of either: 
(a) the lesser of (i) the average daily aggregate gross sales of the Fund's 
Class B shares since the inception of the Fund (not including reinvestment of 
dividends or capital gains distributions), less the average daily aggregate 
net asset value of the Fund's Class B shares redeemed since the Fund's 
inception upon which a CDSC has been imposed or waived, or (ii) the average 
daily net assets of Class B; or (b) the average daily net assets of Class B. 
A portion of the 12b-1 fee equal to up to 0.25% of the Fund's average daily 
net assets is characterized as a service fee within the meaning of the NASD 
guidelines and the remaining portion of the 12b-1 fee, if any, is 
characterized as an asset-based sales charge. Also, Class B shares have a 
conversion feature ("Conversion Feature") under which such shares convert to 
Class A shares after a certain holding period. Details of the Conversion 
Feature are set forth in Section IV below. 

   3. Class C Shares 

   Class C shares are offered without imposition of a FESL, but will in most 
cases be subject to a CDSC of 1.0% on redemptions made within one year after 
purchase. Further information relating to the CDSC is set forth in paragraph 
6 below. In addition, Class C shares, under each Fund's 12b-1 Plan, are 
subject to 12b-1 payments to reimburse Dean Witter Distributors Inc., DWR, 
its affiliates and other broker-dealers for distribution expenses incurred by 
them specifically on behalf of the Class, assessed at the annual rate of up 
to 1.0% of the average daily net assets of the Class. A portion of the 12b-1 
fee equal to up to 0.25% of the Fund's average daily net assets is 
characterized as a service fee within the meaning of NASD guidelines. Unlike 
Class B shares, Class C shares do not have the Conversion Feature. 

   4. Class D Shares 

   Class D shares are offered without imposition of a FESL, CDSC or a 12b-1 
fee for purchases of Fund shares by (i) investors meeting an initial minimum 
investment requirement and (ii) certain other limited categories of 
investors, in each case, as may be approved by the Boards of 
Directors/Trustees of the Funds and as disclosed in each Fund's current 
prospectus. 

   5. Additional Classes of Shares 

   The Boards of Directors/Trustees of the Funds have the authority to create 
additional Classes, or change existing Classes, from time to time, in 
accordance with Rule 18f-3 under the 1940 Act. 

   6. Calculation of the CDSC 

   Any applicable CDSC is calculated based upon the lesser of net asset value 
of the shares at the time of purchase or at the time of redemption. The CDSC 
does not apply to amounts representing an increase in share value due to 
capital appreciation and shares acquired through the reinvestment of 
dividends or 

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

(1)The payments under the 12b-1 Plan for each of Dean Witter American Value 
Fund, Dean Witter Natural Resource Development Securities Inc. and Dean 
Witter Dividend Growth Securities Inc. are assessed at the annual rate of 
1.0% of the lesser of: (a) the average daily aggregate gross sales of the 
Fund's Class B shares since the inception of the Fund's Plan (not including 
reinvestment of dividends or capital gains distributions), less the average 
daily aggregate net asset value of the Fund's Class B shares redeemed since 
the Plan's inception upon which a contingent deferred sales charge has been 
imposed or waived, or (b) the average daily net assets of Class B 
attributable to shares issued, net of related shares redeemed, since 
inception of the Plan. The payments under the 12b-1 Plan for the Dean Witter 
Strategist Fund are assessed at the annual rate of: (i) 1% of the lesser of 
(a) the average daily aggregate gross sales of the Fund's Class B shares 
since the effectiveness of the first amendment of the Plan on November 8, 
1989 (not including reinvestment of dividends or capital gains 
distributions), less the average daily aggregate net asset value of the 
Fund's Class B shares redeemed since the effectiveness of the first amended 
Plan, upon which a contingent deferred sales charge has been imposed or 
waived, or (b) the average daily net assets of Class B attributable to shares 
issued, net of related shares redeemed, since the effectiveness of the first 
amended Plan; plus (ii) 0.25% of the average daily net assets of Class B 
attributable to shares issued, net of related shares redeemed, prior to 
effectiveness of the first amended Plan. 

                                2

capital gains distributions. The CDSC schedule applicable to a Fund and the 
circumstances in which the CDSC is subject to waiver are set forth in each 
Fund's prospectus. 

II. EXPENSE ALLOCATIONS 

   Expenses incurred by a Fund are allocated among the various Classes of 
shares pro rata based on the net assets of the Fund attributable to each 
Class, except that 12b-1 fees relating to a particular Class are allocated 
directly to that Class. In addition, other expenses associated with a 
particular Class (except advisory or custodial fees), may be allocated 
directly to that Class, provided that such expenses are reasonably identified 
as specifically attributable to that Class and the direct allocation to that 
Class is approved by the Fund's Board of Directors/Trustees. 

III. CLASS DESIGNATION 

   All shares of the Funds held prior to July 28, 1997 (other than the shares 
held by certain employee benefit plans established by DWR and its affiliate, 
SPS Transaction Services, Inc., shares of Funds offered with a FESL, and 
shares of Dean Witter Balanced Growth Fund and Dean Witter Balanced Income 
Fund) have been designated Class B shares. Shares held prior to July 28, 1997 
by such employee benefit plans have been designated Class D shares. Shares 
held prior to July 28, 1997 of Funds offered with a FESL have been designated 
Class D shares. In addition, shares of Dean Witter American Value Fund 
purchased prior to April 30, 1984, shares of Dean Witter Strategist Fund 
purchased prior to November 8, 1989 and shares of Dean Witter Natural 
Resource Development Securities Inc. and Dean Witter Dividend Growth 
Securities Inc. purchased prior to July 2, 1984 (with respect to such shares 
of each Fund, including such proportion of shares acquired through 
reinvestment of dividends and capital gains distributions as the total number 
of shares acquired prior to each of the preceding dates in this sentence 
bears to the total number of shares purchased and owned by the shareholder of 
that Fund) have been designated Class D shares. Shares of Dean Witter 
Balanced Growth Fund and Dean Witter Balanced Income Fund held prior to July 
28, 1997 have been designated Class C shares except that shares of Dean 
Witter Balanced Growth Fund and Dean Witter Balanced Income Fund held prior 
to July 28, 1997 that were acquired in exchange for shares of an investment 
company offered with a CDSC have been designated Class B shares and those 
that were acquired in exchange for shares of an investment company offered 
with a FESL have been designated Class A shares. 

IV. THE CONVERSION FEATURE 

   Class B shares held before May 1, 1997 will convert to Class A shares in 
May, 2007, except that Class B shares which are purchased before July 28, 
1997 by trusts for which Dean Witter Trust Company ("DWTC") or Dean Witter 
Trust FSB ("DWTFSB") provides discretionary trustee services will convert to 
Class A shares on or about August 29, 1997 (the CDSC will not be applicable 
to such shares upon the conversion). In all other instances, Class B shares 
of each Fund will automatically convert to Class A shares, based on the 
relative net asset values of the shares of the two Classes on the conversion 
date, which will be approximately ten (10) years after the date of the 
original purchase. Conversions will be effected once a month. The 10 year 
period will be calculated from the last day of the month in which the shares 
were purchased or, in the case of Class B shares acquired through an exchange 
or a series of exchanges, from the last day of the month in which the 
original Class B shares were purchased, provided that shares originally 
purchased before May 1, 1997 will convert to Class A shares in May, 2007. 
Except as set forth below, the conversion of shares purchased on or after May 
1, 1997 will take place in the month following the tenth anniversary of the 
purchase. There will also be converted at that time such proportion of Class 
B shares acquired through automatic reinvestment of dividends owned by the 
shareholder as the total number of his or her Class B shares converting at 
the time bears to the total number of outstanding Class B shares purchased 
and owned by the shareholder. In the case of Class B shares held by a 401(k) 
plan or other employer-sponsored plan qualified under Section 401(a) of the 
Internal Revenue Code (the "Code") and for which DWTC or DWTFSB serves as 
Trustee or the 401(k) Support Services Group of DWR serves as recordkeeper, 
all Class B shares will convert to Class A shares on the conversion date of 
the first shares of a Fund purchased by that plan. In the case of Class B 
shares previously exchanged 

                                3           
<PAGE>
for shares of an "Exchange Fund" (as such term is defined in the prospectus 
of each Fund), the period of time the shares were held in the Exchange Fund 
(calculated from the last day of the month in which the Exchange Fund shares 
were acquired) is excluded from the holding period for conversion. If those 
shares are subsequently re-exchanged for Class B shares of a Fund, the 
holding period resumes on the last day of the month in which Class B shares 
are reacquired. 

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

V. EXCHANGE PRIVILEGES 

   Shares of each Class may be exchanged for shares of the same Class of the 
other Funds and for shares of certain other investment companies without the 
imposition of an exchange fee as described in the prospectuses and statements 
of additional information of the Funds. The exchange privilege of each Fund 
may be terminated or revised at any time by the Fund upon such notice as may 
be required by applicable regulatory agencies as described in each Fund's 
prospectus. 

VI. VOTING 

   Each Class shall have exclusive voting rights on any matter that relates 
solely to its 12b-1 Plan, except that Class B shareholders will have the 
right to vote on any proposed material increase in Class A's expenses, 
including payments under the Class A 12b-1 Plan, if such proposal is 
submitted separately to Class A shareholders. If the amount of expenses, 
including payments under the Class A 12b-1 Plan, is increased materially 
without the approval of Class B shareholders, the Fund will establish a new 
Class A for Class B shareholders whose shares automatically convert on the 
same terms as applied to Class A before the increase. In addition, each Class 
shall have separate voting rights on any matter submitted to shareholders in 
which the interests of one Class differ from the interests of any other 
Class.
