                         Morgan Stanley 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

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. (See "Purchase of
Fund Shares--Alternative Purchase Arrangements.")

   
                         This Prospectus sets forth concisely the information
you should know before investing in the Fund. It should be read and retained

Arrangements   o Class A shares are offered with a front-end sales charge, starting at 5.25% and reduced for larger      
               purchases. Investments of $1 million or more (and investments by certain other limited categories         
               of investors) are not subject to any sales charge at the time of purchase but a contingent                
               deferred sales charge ("CDSC") of 1.0% may be imposed on redemptions within one year of purchase.         
               The Fund is authorized to reimburse the Distributor for specific expenses incurred in                     
               promoting the distribution of the Fund's Class A shares and servicing shareholder accounts pursuant       
               to the Fund's 12b-1 Plan. Reimbursement may in no event exceed an amount equal to                         
               payments at an annual rate of 0.25% of average daily net assets of the Class (see pages 17, 20 and 26).   
                                                                                                                         
               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 17, 23 and 26).                                                          
                                                                                                                         
               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 17, 25 and 26).                                                                                
                                                                                                                         
               o Class D shares are offered only to investors meeting an initial investment minimum of $5 million        
               ($25 million for certain qualified plans) and to certain other limited categories of investors.           
               Class D shares are offered without a front-end sales charge or CDSC and are not subject to any 12b-1 fee  
               (see pages 17, 25 and 26).

                    redeemed if the total value of the account is less than $100 or, if the account     
                    was opened through EasyInvestSM, if after twelve months the shareholder has         
                    invested less than $1,000 in the account (see page 32).                             
- --------------------------------------------------------------------------------------------------------------------
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 10-16).

- ----------
(1)   Reduced for purchases of $25,000 and over (see "Purchase of Fund
      Shares--Initial Sales Charge Alternative--Class A Shares").

(2)   Investments that are not subject to any sales charge at the time of
      purchase are subject to a CDSC of 1.00% that will be imposed on
      redemptions made within one year after purchase, except for certain
      specific circumstances (see "Purchase of Fund Shares--Initial Sales
      Charge Alternative--Class A Shares").

(3)   The CDSC is scaled down to 1.00% during the sixth year, reaching zero
      thereafter.

(4)   Only applicable to redemptions made within one year after purchase (see
     "Purchase of Fund Shares--Level Load Alternative--Class C Shares").
   
(5)   The 12b-1 fee is accrued daily and payable monthly. The entire 12b-1 fee
      payable by Class A and a portion of the 12b-1 fee payable by each of
      Class B and Class C equal to 0.25% of the average daily net assets of the
      Class are currently each characterized as a service fee within the
      meaning of National Association of Securities Dealers, Inc. ("NASD")
      guidelines and are payments made for personal service and/or maintenance
      of shareholder accounts. The remainder of the 12b-1 fee, if any, is an
      asset-based sales charge, and is a distribution fee paid to the
      Distributor to compensate it for the services provided and the expenses
      borne by the Distributor and others in the distribution of the Fund's
      shares (see "Purchase of Fund Shares--Plan of Distribution").

(6)   Upon conversion of Class B shares to Class A shares, such shares will be
      subject to the lower 12b-1 fee applicable to Class A shares. No sales
      charge is imposed at the time of conversion of Class B shares to Class A
      shares. Class C shares do not have a conversion feature and, therefore,
      are subject to an ongoing 1.00% distribution fee (see "Purchase of Fund
      Shares--Alternative Purchase Arrangements").

  Class D ......................................................      $ 7        $22         $ 39        $ 86
You would pay the following expenses on the same $1,000
investment assuming no redemption at the end of the period:
  Class A ......................................................      $62        $81         $102        $162

  Class D ......................................................      $ 7        $22         $ 39        $ 86
</TABLE>
    

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


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


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

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

   
       Morgan Stanley Dean Witter Developing Growth Securities Trust (formerly
named 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.

       Morgan Stanley Dean Witter Advisors Inc. ("MSDW Advisors" 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 is a
wholly-owned subsidiary of Morgan Stanley Dean Witter & Co., a preeminent
global financial services firm that maintains leading market positions in each
of its three primary businesses--securities, asset management and credit
services. The Investment Manager, which was incorporated in July, 1992 under
the name Dean Witter InterCapital Inc., changed its name to Morgan Stanley Dean
Witter Advisors Inc. on June 22, 1998.

       MSDW Advisors and its wholly-owned subsidiary, Morgan Stanley Dean
Witter Services Company Inc. ("MSDW Services"), serve in various investment
management, advisory, management and administrative capacities to 100
investment companies, 28 of which are listed on the New York Stock Exchange,
with combined total assets of approximately $112.9 billion as of October 31,
1998. The Investment Manager also manages portfolios of pension plans, other
institutions and individuals which aggregated approximately $4.4 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. MSDW Advisors has retained MSDW Services 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, 1998, the Fund accrued total compensation to the Investment
Manager amounting to 0.49% of the Fund's average daily net assets and the total
expenses of each Class amounted to 0.94%, 1.69%, 1.69% and 0.69% of the average
daily net assets of Class A, Class B, Class C and Class D, respectively.
    

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



                                       10
<PAGE>

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

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

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

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

       The Fund may invest up to 35% of its total assets in fixed-income
securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities, 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 (including zero coupon
securities), 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
U.S. 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


                                       11
<PAGE>

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

       Foreign securities investments may be affected by changes in currency
rates or exchange control regulations, changes in governmental administration
or economic or monetary policy (in the United States and abroad) or changed
circumstances in dealings between nations. Fluctuations in the relative rates
of exchange between different currencies 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.

   
       Many European countries are about to adopt a single European currency,
the euro (the "Euro Conversion"). The consequences of the Euro Conversion for
foreign exchange rates, interest rates and the value of European securities
eligible for purchase by the Fund are presently unclear. Such consequences may
adversely affect the value and/or increase the volatility of securities held by
the Fund.
    


                                       12
<PAGE>

       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 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-


                                       13
<PAGE>

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.

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

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

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

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


                                       14
<PAGE>

ings) 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.

   
       Year 2000. The investment management services provided to the Fund by
the Investment Manager and the services provided to shareholders by the
Distributor and the Transfer Agent depend on the smooth functioning of their
computer systems. Many computer software systems in use today cannot recognize
the year 2000, but revert to 1900 or some other date, due to the manner in
which dates were encoded and calculated. That failure could have a negative
impact on the handling of securities trades, pricing and account services. The
Investment Manager, the Distributor and the Transfer Agent have been actively
working on necessary changes to their own computer systems to prepare for the
year 2000 and expect that their systems will be adapted before that date, but
there can be no assurance that they will be successful, or that interaction
with other non-complying computer systems will not impair their services at
that time.

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

                                      15

tial and may be reported inconsistently in U.S. and foreign financial
statements. Accordingly, the Fund's investments may be adversely affected.

Objective and Policies" section of the Prospectus and to the "Investment
Practices and Policies" section of the Statement of Additional Information.


PORTFOLIO MANAGEMENT

   
       The Fund's portfolio is actively managed by its Investment Manager with
a view to achieving the Fund's investment objective. No particular emphasis is
given to investments in securities for the purpose of earning current income.
In determining which securities to purchase for the Fund or hold in the Fund's
portfolio, the Investment Manager will rely on information from various
sources, including research, analysis and appraisals of brokers and dealers,
including Dean Witter Reynolds Inc., Morgan Stanley & Co. Incorporated and
other broker-dealers that are affiliates of the Investment Manager, and the
Investment Manager's own analysis of factors it deems relevant. The Fund is
managed within MSDW Advisors' Growth Group, which manages 31 funds and fund
portfolios, with approximately $11.6 billion in assets at October 31, 1998.
Jayne Stevlingson, Senior Vice President of MSDW Advisors and a member of MSDW
Advisors' 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 MSDW Advisors for over five years.

       Pursuant to an order of the Securities and Exchange Commission, the Fund
may effect principal transactions in certain money market instruments with Dean
Witter Reynolds Inc. In addition, the Fund may incur brokerage commissions on
transactions conducted through Dean Witter Reynolds Inc., Morgan Stanley & Co.
Incorporated and other brokers and dealers that are affiliates of MSDW
Advisors.
    

       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,


                                       16
<PAGE>

together with predecessors, of less than three years of continuous operation.
This restriction shall not apply to any obligation of the United States
Government, its agencies or instrumentalities.

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

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

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

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

GENERAL

   
       The Fund offers each class of its shares for sale to the public on a
continuous basis. Pursuant to a Distribution Agreement between the Fund and
Morgan Stanley Dean Witter Distributors Inc. ("MSDW Distributors" or the
"Distributor"), an affiliate of the Investment Manager, shares of the Fund are
distributed by the Distributor and offered by Dean Witter Reynolds Inc.
("DWR"), a selected dealer and subsidiary of Morgan Stanley Dean Witter & Co.,
and other dealers who have entered into selected dealer agreements with the
Distributor ("Selected Broker-Dealers"). It is anticipated that DWR will
undergo a change of corporate name which is expected to incorporate the brand
name of "Morgan Stanley Dean Witter," pending approval of various regulatory
authorities. The principal executive office of the Distributor is located at
Two World Trade Center, New York, New York 10048.

       The Fund offers four classes of shares (each, a "Class"). Class A shares
are sold to investors with an initial sales charge that declines to zero for
larger purchases; however, Class A shares sold without an initial sales charge
are subject to a contingent deferred sales charge ("CDSC") of 1.0% if redeemed
within one year of purchase, except for certain specific circumstances. Class B
shares are sold without an initial sales charge but are subject to a CDSC
(scaled down from 5.0% to 1.0%) payable upon most redemptions within six years
after purchase. (Class B shares purchased by certain qualified plans are
subject to a CDSC scaled down from 2.0% to 1.0% if redeemed within three years
after purchase.) Class C shares are sold without an initial sales charge but
are subject to a CDSC of 1.0% on most redemptions made within one year after
purchase. Class D shares are sold without an initial sales charge or CDSC and
are available only to investors meeting an initial investment minimum of $5
million ($25 million for certain qualified plans), and to certain other limited
categories of investors. At the discretion of the Board of Trustees of the
Fund, Class A shares may be sold to categories of investors in addition to
those set forth in this prospectus at net asset value without a front-end sales
charge, and Class D shares may be sold to certain other categories of
investors, in each case as may be described in the then current prospectus of
the Fund. See "Alternative Purchase Arrangements--Selecting a Particular Class"
for a discussion of factors to consider in selecting which Class of shares to
purchase.

       The minimum initial purchase is $1,000 for each Class of shares,
although Class D shares are only available to persons investing $5 million ($25
million for certain qualified plans) or more and to certain other limited
categories of investors. For the purpose of meeting the minimum $5 million (or
$25 million) initial investment for Class D shares, and subject to the $1,000
minimum initial investment for each Class of the Fund, an investor's existing
holdings of Class A and Class D shares of the Fund and other Morgan Stanley
Dean Witter Funds that
    


                                       17
<PAGE>

   
are multiple class funds ("Morgan Stanley Dean Witter Multi-Class Funds") and
shares of Morgan Stanley Dean Witter Funds sold with a front-end sales charge
("FSC Funds") and concurrent investments in Class D shares of the Fund and
other Morgan Stanley Dean Witter Multi-Class Funds will be aggregated.
Subsequent purchases of $100 or more may be made by sending a check, payable to
Morgan Stanley Dean Witter Developing Growth Securities Trust, directly to
Morgan Stanley Dean Witter Trust FSB (the "Transfer Agent" or "MSDW Trust") at
P.O. Box 1040, Jersey City, NJ 07303 or by contacting a Morgan Stanley Dean
Witter Financial Advisor or other Selected Broker-Dealer representative. When
purchasing shares of the Fund, investors must specify whether the purchase is
for Class A, Class B, Class C or Class D shares. If no Class is specified, the
Transfer Agent will not process the transaction until the proper Class is
identified. The minimum initial purchase in the case of investments through
EasyInvestSM, 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. The minimum initial purchase
in the case of an "Education IRA" is $500, if the Distributor has reason to
believe that additional investments will increase the investment in the account
to $1,000 within three years. In the case of investments pursuant to (i)
Systematic Payroll Deduction Plans (including Individual Retirement Plans),
(ii) the MSDW Advisors mutual fund asset allocation program and (iii) fee-based
programs approved by the Distributor, pursuant to which participants pay an
asset based fee for services in the nature of investment advisory or
administrative services, the Fund, in its discretion, may accept investments
without regard to any minimum amounts which would otherwise be required,
provided, in the case of Systematic Payroll Deduction Plans, that the
Distributor has reason to believe that additional investments will increase the
investment in all accounts under such Plans to at least $1,000. Certificates
for shares purchased will not be issued unless 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. 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


                                       18
<PAGE>

applicable to shares of those Classes. The ongoing distribution fees that are
imposed on Class A, Class B and Class C shares will be imposed directly against
those Classes and not against all assets of the Fund and, accordingly, such
charges against one Class will not affect the net asset value of any other
Class or have any impact on investors choosing another sales charge option. See
"Plan of Distribution" and "Redemptions and Repurchases."

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

       Class A Shares. Class A shares are sold at net asset value plus an
initial sales charge of up to 5.25%. The initial sales charge is reduced for
certain purchases. Investments of $1 million or more (and investments by
certain other limited categories of investors) are not subject to any sales
charges at the time of purchase but are subject to a CDSC of 1.0% on
redemptions made within one year after purchase, except for certain specific
circumstances. Class A shares are also subject to a 12b-1 fee of up to 0.25% of
the average daily net assets of the Class. See "Initial Sales Charge
Alternative--Class A Shares."
   
       Class B Shares. Class B shares are offered at net asset value with no
initial sales charge but are subject to a CDSC (scaled down from 5.0% to 1.0%)
if redeemed within six years of purchase. (Class B shares purchased by certain
qualified 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


                                       19
<PAGE>

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 determine that they do not wish to be subject to a front-end
sales charge and they are uncertain as to the length of time they intend to
hold their shares.

   
       For the purpose of meeting the $5 million (or $25 million) minimum
investment amount for Class D shares, holdings of Class A and Class D shares in
all Morgan Stanley Dean Witter Multi-Class Funds, shares of FSC Funds and
shares of Morgan Stanley 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:

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


                                       20
<PAGE>

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 Morgan Stanley 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 Morgan Stanley 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 Morgan Stanley Dean Witter Funds
previously purchased at a price including a front-end sales charge (including
shares of the Fund and other Morgan Stanley 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
    


                                       21
<PAGE>

   
$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 that, together with the current
investment amount, is equal to at least $5 million ($25 million for certain
qualified plans), such investor is eligible to purchase Class D shares subject
to the $1,000 minimum initial investment requirement of that Class of the Fund.
See "No Load Alternative--Class D Shares" below.
    

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

   
       Letter of Intent. The foregoing schedule of reduced sales charges will
also be available to investors who enter into a written Letter of Intent
providing for the purchase, within a thirteen-month period, of Class A shares
of the Fund from DWR or other Selected Broker-Dealers. The cost of Class A
shares of the Fund or shares of other Morgan Stanley 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 Morgan Stanley
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 MSDW Trust (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, administrative and/or brokerage services
(such investments are subject to all of the terms and conditions of such
programs, which may include termination fees, mandatory redemption upon
termination and such other circumstances as specified in the programs'
agreements, and restrictions on transferability of Fund shares);

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

       (4) Qualified Retirement Plans for which MSDW Trust serves as Trustee or
DWR's Retirement Plan Services serves as recordkeeper pursuant to a written
Recordkeeping Services Agreement whose Class B shares have converted to Class A
shares, regardless of the plan's asset size or number of eligible employees;

       (5) investors who are clients of a Morgan Stanley Dean Witter Financial
Advisor who joined Morgan Stanley 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 Financial
Advisor'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.

CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE--
CLASS B SHARES


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

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

       In the case of Class B shares of the Fund purchased on or after July 28,
1997 by Qualified Retirement Plans for which MSDW Trust serves as Trustee or
DWR's Retirement Plan Services serves as recordkeeper pursuant to a written
Recordkeeping Services Agreement, shares held for three years or more after
purchase (calculated as described in the paragraph above) will not be subject
to any CDSC upon redemption. However, shares redeemed earlier than three years
after purchase may be subject to a CDSC (calculated as described in the
paragraph above), the percentage of which will depend on how long the shares
have been held, as set forth in the following table:

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


                                       23
<PAGE>

   
dividends or distributions and/or shares acquired in exchange for shares of FSC
Funds or of other Morgan Stanley Dean Witter Funds acquired in exchange for
such shares. Moreover, in determining whether a CDSC is applicable it will be
assumed that amounts described in (i), (ii) and (iii) above (in that order) are
redeemed first. In addition, no CDSC will be imposed on redemptions of shares
which are attributable to reinvestment of dividends or distributions from, or
the proceeds of, certain Unit Investment Trusts.
    

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

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

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

   
       (3) all redemptions of shares held for the benefit of a participant in a
Qualified Retirement Plan which offers investment companies managed by the
Investment Manager or its subsidiary, MSDW Services, as self-directed
investment alternatives and for which MSDW Trust serves as Trustee or DWR's
Retirement Plan Services serves as recordkeeper pursuant to a written
Recordkeeping Services Agreement ("Eligible Plan"), provided that either: (A)
the plan continues to be an Eligible Plan after the redemption; or (B) the
redemption is in connection with the complete termination of the plan involving
the distribution of all plan assets to participants; and

       (4) certain redemptions pursuant to the Fund's Systematic Withdrawal
Plan (see "Shareholder Services--Systematic Withdrawal Plan").
    

       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


                                       24
<PAGE>

   
and owned by the shareholder. In the case of Class B shares held by a Qualified
Retirement Plan for which MSDW Trust serves as Trustee or DWR's Retirement Plan
Services serves as recordkeeper pursuant to a written Recordkeeping Services
Agreement, the plan is treated as a single investor and all Class B shares will
convert to Class A shares on the conversion date of the first shares of a
Morgan Stanley 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 Morgan Stanley Dean Witter Multi-Class Fund, the holding period resumes on
the last day of the month in which Class B shares are reacquired.
    

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

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

LEVEL LOAD ALTERNATIVE--CLASS C SHARES

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

NO LOAD ALTERNATIVE--CLASS D SHARES

   
       Class D shares are offered without any sales charge on purchase or
redemption and without any 12b-1 fee. Class D shares are offered only to
investors meeting an initial investment minimum of $5 million ($25 million for
Qualified Retirement Plans for which MSDW Trust serves as Trustee or DWR's
Retirement Plan Services serves as recordkeeper pursuant to a written
Recordkeeping Services Agreement) and the following categories of investors:
(i) investors participating in the MSDW Advisors mutual fund asset allocation
program pursuant to which such persons pay an asset based fee; (ii) persons
participating in a fee-based program approved by the Distributor, pursuant to
which such persons pay an asset based fee for services in the nature of
investment advisory, administrative and/or brokerage services (subject to all
of the terms and conditions of such programs referred to in (i) and (ii) above,
which may include termination fees, mandatory redemption upon termination and
such other
    


                                       25
<PAGE>

   
circumstances as specified in the programs' agreements, and restrictions on
transferability of Fund shares); (iii) employee benefit plans maintained by
Morgan Stanley Dean Witter & Co. or any of its subsidiaries for the benefit of
certain employees of Morgan Stanley Dean Witter & Co. and its subsidiaries;
(iv) certain Unit Investment Trusts sponsored by DWR; (v) certain other
open-end investment companies whose shares are distributed by the Distributor;
(vi) investors who were shareholders of Dean Witter Retirement Series on
September 11, 1998 (with respect to additional purchases for their former Dean
Witter Retirement Series accounts); and (vii) other categories of investors, at
the discretion of the Board, as disclosed in the then current prospectus of the
Fund. Investors who require a $5 million (or $25 million) minimum initial
investment to qualify to purchase Class D shares may satisfy that requirement
by investing that amount in a single transaction in Class D shares of the Fund
and other Morgan Stanley 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 (or $25 million) minimum investment
amount, holdings of Class A and Class D shares in all Morgan Stanley Dean
Witter Multi-Class Funds, shares of FSC Funds and shares of Morgan Stanley 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 Morgan Stanley Dean
Witter Financial Advisors 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.
    


                                       26
<PAGE>

   
       For the fiscal year ended September 30, 1998, Class B shares of the Fund
accrued payments under the Plan amounting to $7,916,623, which amount is equal
to 1.0% of the average daily net assets of Class B for the fiscal year. These
payments were calculated pursuant to clause (b) of the compensation formula
under the Plan. For the fiscal year ended September 30, 1998, Class A and Class
C shares of the Fund accrued payments under the Plan amounting to $10,097 and
$21,641, respectively, which amounts are equal to 0.25% and 1.0% of the average
daily net assets of Class A and Class C, respectively, for the fiscal year.

       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. 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 $24,581,350 at September 30, 1998, which was equal to 4.12% of the net
assets of Class B on such date. Because there is no requirement under the Plan
that the Distributor be reimbursed for all distribution expenses or any
requirement that the Plan be continued from year to year, this excess amount
does not constitute a liability of the Fund. Although there is no legal
obligation for the Fund to pay expenses incurred in excess of payments made to
the Distributor under the Plan and the proceeds of CDSCs paid by investors upon
redemption of shares, if for any reason the Plan is terminated the Trustees
will consider at that time the manner in which to treat such expenses. Any
cumulative expenses incurred, but not yet recovered through distribution fees
or CDSCs, may or may not be recovered through future distribution fees or
CDSCs.

       In the case of Class A and Class C shares, expenses incurred pursuant to
the Plan in any calendar year in excess of 0.25% or 1.0% of the average daily
net assets of Class A or Class C, respectively, will not be reimbursed by the
Fund through payments in any subsequent year, except that expenses representing
a gross sales commission credited to Morgan Stanley Dean Witter Financial
Advisors and other Selected Broker-Dealer representatives at the time of sale
may be reimbursed in the subsequent calendar year. The Distributor has advised
the Fund that unreimbursed expenses representing a gross sales commission
credited to Morgan Stanley Dean Witter Financial Advisors and other Selected
Broker-Dealer representatives at the time of sale totalled $14,710 in the case
of Class C at December 31, 1997, which amount was equal to 0.72% of the net
assets of Class C on such date, and that there were no such expenses that may
be reimbursed in the subsequent year in the case of Class A on such date. No
interest or other financing charges will be incurred on any Class A or Class C
distribution expenses incurred by the Distributor under the Plan or on any
unreimbursed expenses due to the Distributor pursuant to the Plan.
    

DETERMINATION OF NET ASSET VALUE

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

       In the calculation of the Fund's net asset value: (1) an equity
portfolio security listed or traded on the New York or American Stock Exchange
or other domestic or foreign exchange is valued at its latest sale price on
that exchange prior to the time assets


                                       27
<PAGE>

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 Morgan Stanley Dean Witter Fund),
unless the shareholder requests that they be paid in cash. Shares so acquired
are acquired at net asset value and are not subject to the imposition of a
front-end sales charge or a CDSC (see "Redemptions and Repurchases").

       EasyInvestSM. Shareholders may subscribe to EasyInvest, an automatic
purchase plan which provides for any amount from $100 to $5,000 to be
transferred automatically from a checking or savings account or following
redemption of shares of a Morgan Stanley 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").

       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").

       Systematic Withdrawal Plan. A systematic withdrawal plan (the
"Withdrawal Plan") is available for shareholders whose shares of Morgan Stanley
Dean Witter Funds have an aggregate value of $10,000 or more. Shares of any
Fund from which redemptions will be made pursuant to the Plan must have a value
of $1,000 or more (referred to as a "SWP Fund"). The required share values are
determined on the date the shareholder establishes the Withdrawal Plan. The
Withdrawal Plan provides for monthly, quarterly, semi-annual or annual payments
in any amount not less than $25, or in any whole
    

                                       28
<PAGE>

   
percentage of the value of the SWP Funds' shares, on an annualized basis. Any
applicable CDSC will be imposed on shares redeemed under the Withdrawal Plan
(see "Purchase of Fund Shares"), except that the CDSC, if any, will be waived
on redemptions under the Withdrawal Plan of up to 12% annually of the value of
each SWP Fund account, based on the share values next determined after the
shareholder establishes the Withdrawal Plan. Redemptions for which this CDSC
waiver policy applies may be in amounts up to 1% per month, 3% per quarter, 6%
semi-annually or 12% annually. Under this CDSC waiver policy, amounts withdrawn
each period will be paid by first redeeming shares not subject to a CDSC
because the shares were purchased by the reinvestment of dividends or capital
gains distributions, the CDSC period has elapsed or some other waiver of the
CDSC applies. If shares subject to a CDSC must be redeemed, shares held for the
longest period of time will be redeemed first and continuing with shares held
the next longest period of time until shares held the shortest period of time
are redeemed. 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,
quarterly, semi-annual or annual amount.

       A shareholder may suspend or terminate participation in the Withdrawal
Plan at any time. A shareholder who has suspended participation may resume
payments under the Withdrawal Plan, without requiring a new determination of
the account value for the 12% CDSC waiver. The Withdrawal Plan may be
terminated or revised at any time by the Fund.

       Prior to adding an additional SWP Fund to an existing Withdrawal Plan,
the required $10,000/  $1,000 share values must be met, to be calculated on the
date the shareholder adds the additional SWP Fund. However, the addition of a
new SWP Fund will not change the account value for the 12% CDSC waiver for the
SWP Funds already participating in the Withdrawal Plan.

       Withdrawal Plan payments should not be considered 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 Morgan Stanley Dean Witter Financial
Advisor or other Selected Broker-Dealer representative 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 advisor.

       For further information regarding plan administration, custodial fees
and other details, investors should contact their Morgan Stanley Dean Witter
Financial Advisor or other Selected Broker-Dealer representative or the
Transfer Agent.
    
EXCHANGE PRIVILEGE

   
       Shares of each Class may be exchanged for shares of the same Class of
any other Morgan Stanley Dean Witter Multi-Class Fund without the imposition of
any exchange fee. Shares may also be exchanged for shares of the following
funds: Morgan Stanley Dean Witter Short-Term U.S. Treasury Trust, Morgan
Stanley Dean Witter Limited Term Municipal Trust, Morgan Stanley Dean Witter
Short-Term Bond Fund and five Morgan Stanley Dean Witter Funds which are money
market funds (the "Exchange Funds"). Class A shares may also be exchanged for
shares of Morgan Stanley Dean Witter Multi-State Municipal Series Trust and
Morgan Stanley Dean Witter Hawaii Municipal Trust, which are Morgan Stanley
Dean Witter Funds sold with a front-end sales charge ("FSC Funds"). Exchanges
may be made after the shares of the Fund acquired by
    


                                       29
<PAGE>

purchase (not by exchange or dividend reinvestment) have been held for thirty
days. There is no waiting period for exchanges of shares acquired by exchange
or dividend reinvestment.

   
       An exchange to another Morgan Stanley Dean Witter Multi-Class Fund, any
FSC 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 Morgan Stanley Dean Witter Multi-Class Funds, FSC 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 Morgan Stanley Dean
Witter Multi-Class Fund, the holding period previously frozen when the first
exchange was made resumes on the last day of the month in which shares of a
Morgan Stanley Dean Witter Multi-Class Fund are reacquired. Thus, the CDSC is
based upon the time (calculated as described above) the shareholder was
invested in shares of a Morgan Stanley Dean Witter Multi-Class 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. 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 Morgan Stanley Dean Witter
Multi-Class 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 Morgan Stanley 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 Morgan Stanley
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 mar-
    


                                       30
<PAGE>

   
gin accounts with DWR or another Selected Broker-Dealer are referred to their
Morgan Stanley Dean Witter Financial Advisor or other Selected Broker-Dealer
representative regarding restrictions on exchange of shares of the Fund pledged
in the margin account.
    

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

   
       If DWR or another Selected Broker-Dealer is the current dealer of record
and its account numbers are part of the account information, shareholders may
initiate an exchange of shares of the Fund for shares of any of the Morgan
Stanley Dean Witter Funds (for which the Exchange Privilege is available)
pursuant to this Exchange Privilege by contacting their Morgan Stanley Dean
Witter Financial Advisor or other Selected Broker-Dealer representative (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 Morgan Stanley
Dean Witter Financial Advisor or other Selected Broker-Dealer representative,
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 Morgan Stanley Dean Witter Funds in the past.

       Shareholders should contact their Morgan Stanley Dean Witter Financial
Advisor or other Selected Broker-Dealer representative or the Transfer Agent
for further information about the Exchange Privilege.

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

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

Repurchase. DWR and other Selected Broker-Dealers are authorized to repurchase
shares represented by a share certificate which is delivered to any of their
offices. Shares held in a shareholder's account without a share certificate may
also be repurchased by DWR and other Selected Broker-Dealers upon the
telephonic request of the shareholder. The repurchase price is the net asset
value next computed (see "Purchase of Fund Shares") after such purchase order
is received by DWR or other Selected Broker-Dealer, reduced by any applicable
CDSC.

       The CDSC, if any, will be the only fee imposed by the Fund or the
Distributor. 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 Morgan Stanley Dean Witter Financial
Advisor or other Selected Broker-Dealer representative 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 EasyInvestSM, if after twelve months the shareholder has
invested less than $1,000 in the account. However, before the Fund redeems such
shares and sends the proceeds to the shareholder, it will notify the
shareholder that the value of the shares is less than the applicable amount and
allow the shareholder sixty days to make an additional investment in an amount
which will increase the value of his or her account to at least the applicable
amount before the redemption is processed. No CDSC will be imposed on any
involuntary redemption.

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

       Dividends and Distributions. The Fund declares dividends separately for
each Class of shares and intends to distribute substantially all of its net
investment income and net realized short-term and long-term capital gains, if
any, at least once each year. The Fund may, however, determine to retain all or
part of any net long-term capital gains in any year for reinvestment.

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

   
       Taxes. Because the Fund intends to distribute all of its net investment
income and net capital gains (to the extent not offset by capital loss
carryovers) to shareholders and remain qualified as a regulated investment
company under Subchapter M of the Internal Revenue Code, it is not expected
that the Fund will be required to pay any federal income tax. Shareholders who
are required to pay taxes on their income will normally have to pay federal
income taxes, and any state and local 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. Shareholders will also be notified of their proportionate share of
long-term capital gains distributions that are eligible for a reduced rate of
tax under the Taxpayer Relief Act of 1997. To avoid being subject to a 31%
federal backup withholding tax on taxable dividends, capital gains
distributions and the proceeds of redemptions and repurchases, shareholders'
taxpayer identification numbers must be furnished and certified as to accuracy.
 

       Shareholders should consult their tax advisors as to the applicability
of the foregoing to their current situation.
    


                                       33

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 MSDW Advisors, MSDW
Services and MSDW Distributors are subject to a strict Code of Ethics adopted
by those companies. The Code of Ethics is intended to ensure that the interests
of
    


                                       34
<PAGE>

   
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 Morgan
Stanley 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
Morgan Stanley 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.

     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. The Investment Manager
has retained MSDW Services to provide its administrative services under the
Agreement.

     Expenses not expressly assumed by the Investment Manager under the
Agreement or by the Distributor of the Fund's shares, Morgan Stanley Dean
Witter Distributors Inc. ("MSDW Distributors" or
    


                                       5
<PAGE>

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. Such expenses 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 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. The management fee is allocated
among the Classes pro rata based on the net assets of the Fund attributable to
each Class. For the fiscal years ended September 30, 1996, 1997 and 1998, the
Fund accrued to the Investment Manager total compensation in the amounts of
$3,194,151, $3,729,759 and $3,924,618, 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 BOARD OF TRUSTEES, THE INDEPENDENT TRUSTEES, AND THE COMMITTEES

     The Board of Trustees consists of nine (9) trustees. These same
individuals also serve as directors or trustees for all of the Morgan Stanley
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 85
Morgan Stanley Dean Witter Funds, comprised of 121 portfolios. As of October
31, 1998, the Morgan Stanley Dean Witter Funds had total net assets of
approximately $109.2 billion and more than six million shareholders.

     Seven Trustees (77% of the total number) have no affiliation or business
connection with MSDW Advisors or any of its affiliated persons and do not own
any stock or other securities issued by MSDW Advisors' parent company, MSDW.
These are the "disinterested" or "independent" Trustees. Four of the seven
independent Trustees are also Independent Trustees of the TCW/DW Funds.

     Law and regulation establish both general guidelines and specific duties
for the Independent Trustees. The Morgan Stanley 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 Independent Trustees serve as members of the Audit Committee.
Three of them also serve as members of the Derivatives Committee. In addition,
three of the Trustees, including two Independent Trustees, serve as members of
the Insurance Committee. During the calendar year ended December 31, 1997, the
Audit Committee, the Derivatives Committee and the Independent Trustees held a
combined total of seventeen meetings.

     The Independent Trustees are 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 Morgan Stanley 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; and 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.

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

     Finally, the Board of each Fund has formed an Insurance Committee to
review and monitor the insurance coverage maintained by the Fund.

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


     The Independent Trustees and the Funds' management believe that having the
same Independent Trustees for each of the Morgan Stanley 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 of the caliber, experience
and business acumen of the individuals who serve as Independent Trustees of the
Morgan Stanley Dean Witter Funds.

COMPENSATION OF INDEPENDENT TRUSTEES

     The Fund pays each Independent Trustee an annual fee of $800 plus a per
meeting fee of $50 for meetings of the Board of Trustees, the Independent
Trustees or Committees of the Board of Trustees attended by the Trustee (the
Fund pays the Chairman of the Audit Committee an additional annual fee of
$750). If a Board meeting and a meeting of the Independent Trustees or a
Committee meeting, or a meeting of the Independent Trustees and/or more than
one Committee meeting, take place on a single day, the Trustees are paid a
single meeting fee by the Fund. The Fund also reimburses such Trustees for
travel and other out-of-pocket expenses incurred by them in connection with
attending such meetings. Trustees who are or have been employed by the
Investment Manager or an affiliated company receive no compensation or expense
reimbursement from the Fund for their services as Trustee. Mr. Haire currently
serves as Chairman of the Audit Committee. Prior to June 1, 1998, Mr. Haire
also served as Chairman of the Independent Trustees, for which services the
Fund paid him an additional annual fee of $1,200.

     The following table illustrates the compensation paid to the Fund's
Independent Trustees by the Fund for the fiscal year ended September 30, 1998.

     As of the date of this Statement of Additional Information, 57 of the
Morgan Stanley 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 Morgan Stanley 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 29.41% of his or her Eligible Compensation plus
0.4901667% 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 58.82% 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.


     The following table illustrates the retirement benefits accrued to the
Fund's Independent Trustees by the Fund for the fiscal year ended September 30,
1998 and by the 57 Morgan Stanley Dean Witter Funds (including the Fund) for
the year ended December 31, 1997, and the estimated retirement benefits for the
Fund's Independent Trustees, to commence upon their retirement, from the Fund
as of September 30, 1998 and from the 57 Morgan Stanley Dean Witter Funds as of
December 31, 1997.

- --------------------
(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.

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

     U.S. Government Securities. As discussed in the Prospectus, the Fund may
invest in, among other securities, securities issued by the U.S. Government,
its agencies or instrumentalities. Such securities include:

     (1) U.S. Treasury bills (maturities of one year or less), U.S. Treasury
   notes (maturities of one to ten years) and U.S. Treasury bonds (generally
   maturities of greater than ten years), all of which are direct obligations
   of the U.S. Government and, as such, are backed by the "full faith and
   credit" of the United States.

     (2) Securities issued by agencies and instrumentalities of the U.S.
   Government which are backed by the full faith and credit of the United
   States. Among the agencies and instrumentalities issuing such obligations
   are the Federal Housing Administration, the Government National Mortgage
   Association ("GNMA"), the Department of Housing and Urban Development, the
   Export-Import Bank, the Farmers Home Administration, the General Services
   Administration, the Maritime Administration and the Small Business
   Administration. The maturities of such obligations range from three months
   to 30 years.

     (3) Securities issued by agencies and instrumentalities which are not
   backed by the full faith and credit of the United States, but whose issuing
   agency or instrumentality has the right to borrow, to meet its obligations,
   from an existing line of credit with the U.S. Treasury. Among the agencies
   and instrumentalities issuing such obligations are the Tennessee Valley
   Authority, the Federal National Mortgage Association ("FNMA"), the Federal
   Home Loan Mortgage Corporation ("FHLMC") and the U.S. Postal Service.

     (4) Securities issued by agencies and instrumentalities which are not
   backed by the full faith and credit of the United States, but which are
   backed by the credit of the issuing agency or instrumentality. Among the
   agencies and instrumentalities issuing such obligations are the Federal
   Farm Credit System and the Federal Home Loan Banks.

     Neither the value nor the yield of the U.S. Government securities which
may be invested in by the Fund are guaranteed by the U.S. Government. Such
values and yields will fluctuate with changes in


                                       13
<PAGE>

prevailing interest rates and other factors. Generally, as prevailing interest
rates rise, the value of any U.S. Government securities held by the Fund will
fall. Such securities with longer maturities generally tend to produce higher
yields and are subject to greater market fluctuation as a result of changes in
interest rates rather than debt securities with shorter maturities. The Fund is
not limited as to the maturities of the U.S. Government securities in which it
may invest.

     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.

   
     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, 1998.
    

     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.


                                       14
<PAGE>

     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 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 net
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 in which it will continually maintain cash or U.S.
Government securities or other liquid portfolio securities equal in
    


                                       15
<PAGE>

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 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 Turnover. 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.


                                       16
<PAGE>

     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.

     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, 1996, 1997 and
1998, the Fund paid a total of $1,361,260, $1,739,634 and $2,210,633,
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


                                       17
<PAGE>

   
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 utilizes a pro rata allocation process based
on the size of the Morgan Stanley 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, 1998, the Fund paid $1,884,151 in brokerage
commissions in connection with transactions in the aggregate amount of
$717,843,386 to brokers because of research services provided.

     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.

     Consistent with the policy described above, brokerage transactions in
securities listed on exchanges or admitted to unlisted trading privileges may
be effected through DWR, Morgan Stanley & Co. Incorporated ("MS & Co.") 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, 1996,
1997 and 1998, the Fund paid a total of $133,555, $39,264 and $100,032,
respectively, in brokerage commissions to DWR. For the fiscal year
    


                                       18
<PAGE>

   
ended September 30, 1998, the brokerage commissions paid to DWR represented
approximately 4.53% 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 6.68% of the aggregate dollar value of all portfolio
transactions of the Fund during the year for which commissions were paid.
During the period June 1, 1997 through September 30, 1997 and during the fiscal
year ended September 30, 1998, the Fund paid a total of $23,533 and $125,345,
respectively, in brokerage commissions to MS & Co., which broker-dealer became
an affiliate of the Investment Manager on May 31, 1997 upon consummation of the
merger of Dean Witter, Discover & Co. with Morgan Stanley Group Inc. During the
fiscal year ended September 30, 1998, the brokerage commissions paid to MS &
Co. represented approximately 5.67% of the total brokerage commissions paid by
the Fund during the year and were paid on account of transactions having an
aggregate dollar value equal to approximately 5.80% of the aggregate dollar
value of all portfolio transactions of the Fund during the year for which
commissions were paid.

     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, 1996, 1997 and
1998, the Fund did not effect any principal transactions with DWR.

     During the fiscal year ended September 30, 1998, 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
Morgan Stanley 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 MSDW. 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 had an initial term ending April
30, 1998 and will remain in effect from year to year thereafter if approved by
the Board. At their meeting held on April 30, 1998, the Trustees of the Fund,
including a majority of the Independent Trustees, approved the continuation of
the Distribution Agreement until April 30, 1999.

     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 Morgan
Stanley Dean Witter Financial Advisors and other selected broker-dealer
representatives. The Distributor also pays certain expenses in connection 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
    


                                       19

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 (a) approximately $810,000, $1,278,000 and $1,202,000 in
contingent deferred sales charges from Class B for the fiscal years ended
September 30, 1996, 1997 and 1998, respectively, (b) approximately $2,700 in
contingent deferred sales charges from Class C for the fiscal year ended
September 30, 1998, (c) approximately $40 in contingent deferred sales charges
from Class A for the fiscal year ended September 30, 1998, and (d)
approximately $56,000 in front-end sales charges from Class A for the fiscal
year ended September 30, 1998, none of which was retained by the Distributor.
No front-end sales charges were received from Class A during the fiscal year
ended September 30, 1997, and no contingent deferred sales charges were
received from Class A or Class C during the fiscal year ended September 30,
1997.
    

     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 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


                                       20
<PAGE>

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. Class B shares of the Fund
accrued amounts payable to the Distributor under the Plan, during the fiscal
year ended September 30, 1998, of $7,916,623. This amount is equal to 1.0% of
the average daily net assets of Class B for the fiscal year and was calculated
pursuant to clause (b) of the compensation formula under the Plan. For the
fiscal year ended September 30, 1998, Class A and Class C shares of the Fund
accrued payments under the Plan amounting to $10,097 and $21,641, respectively,
which amounts are equal to 0.25% and 1.0% of the average daily net assets of
Class A and Class C, respectively, for the fiscal year.
    

     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 Financial Advisors 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 Financial Advisors 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 employer sponsored 401(k) and
other plans qualified under Section 401(a) of the Internal Revenue Code
("Qualified Retirement Plans") for which Morgan Stanley Dean Witter Trust FSB
("MSDW Trust") serves as Trustee or DWR's Retirement Plan Services serves as
recordkeeper pursuant to a written Recordkeeping Services Agreement, the
Investment Manager compensates DWR's Financial Advisors 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 Financial Advisors 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 Class B shares purchased on or after July 28, 1997 by Qualified
Retirement Plans for which MSDW Trust serves as Trustee or DWR's Retirement
Plan Services serves as recordkeeper pursuant to a written Recordkeeping
Services Agreement, DWR compensates its Financial Advisors 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 Financial Advisors 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 Financial Advisors of record.

     With respect to Class D shares other than shares held by participants in
the MSDW Advisors mutual fund asset allocation program, the Investment Manager
compensates DWR's Financial Advisors 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 redeemed in the second year after
purchase. The Investment Manager also compensates DWR's Financial Advisors 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 Financial Advisors of record (not including accounts of
participants in the MSDW Advisors mutual fund asset allocation program).
    


                                       21
<PAGE>

   
     The gross sales credit is a charge which reflects commissions paid by DWR
to its Financial Advisors 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 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 Morgan Stanley Dean Witter
Financial Advisors and other selected broker-dealer representatives, 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 Morgan Stanley Dean Witter Financial Advisors and other selected
broker-dealer representatives (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.

     Each Class paid 100% of the amounts accrued under the Plan with respect to
that Class for the fiscal year ended September 30, 1998 to the Distributor. The
Distributor and DWR estimate that they have spent, pursuant to the Plan,
$80,707,944 on behalf of Class B since the inception of the Plan. It is
estimated that this amount was spent in approximately the following ways: (i)
6.32% ($5,101,908)--advertising and promotional expenses; (ii) 0.63%
($510,811)--printing of prospectuses for distribution to other than current
shareholders; and (iii) 93.05% ($75,095,225)--other expenses, including the
gross sales credit and the carrying charge, of which 18.68% ($14,025,358)
represents carrying charges, 33.26% ($24,977,576) represents commission credits
to DWR branch offices and other selected broker-dealers for payments of
commissions to Morgan Stanley Dean Witter Financial Advisors and other selected
broker-dealer representatives, and 48.06% ($36,092,291) represents overhead and
other branch office distribution-related expenses. The amounts accrued by Class
A and Class C for distribution during the fiscal year ended September 30, 1998
were for expenses which relate to compensation of sales personnel and
associated overhead expenses.
    

     In the case of Class B shares, 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


                                       22
<PAGE>

   
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 $24,581,350 as of
September 30, 1998. 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, MSDW Advisors, MSDW Services, DWR 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. The
most recent continuance of the Plan for one year, until April 30, 1999, 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 30, 1998. 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 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.


                                       23
<PAGE>

   
     Generally, trading in foreign securities, as well as corporate bonds,
United States government securities and money market instruments, is
substantially completed each day at various times prior to the close of the New
York Stock Exchange. The values of such securities used in computing the net
asset value of the Fund's shares are determined as of such times. Foreign
currency exchange rates are also generally determined prior to the close of the
New York Stock Exchange. Occasionally, events which may affect the values of
such securities and such exchange rates may occur between the times at which
they are determined and the close of the New York Stock Exchange and will
therefore not be reflected in the computation of the Fund's net asset value. If
events that may affect the value of such securities occur during such period,
then these securities may be 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, Reverend Dr. Martin
Luther King, Jr. 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 Morgan Stanley Dean Witter Funds that are
multiple class funds ("Morgan Stanley Dean Witter Multi-Class Funds") or shares
of other Morgan Stanley 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 Morgan Stanley Dean Witter Trust
FSB (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.


                                       24
<PAGE>

     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 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 Morgan
Stanley 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 Morgan Stanley 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 Morgan Stanley 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 Qualified Retirement 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 Qualified
Retirement 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 Morgan Stanley Dean Witter Fund (see
"Shareholder Services--Targeted Dividends"), plus (c) the current net asset
value of shares acquired in exchange for (i) shares of Morgan Stanley Dean
Witter front-end sales charge funds, or (ii) shares of other Morgan Stanley
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 Qualified
Retirement 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
    


                                       25
<PAGE>

   
for shares of Morgan Stanley Dean Witter front-end sales charge funds, or for
shares of other Morgan Stanley 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
Qualified Retirement 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 of the month. The following table sets forth the rates of the CDSC
applicable to most Class B shares of the Fund:

     The following table sets forth the rates of the CDSC applicable to Class B
shares of the Fund purchased on or after July 28, 1997 by Qualified Retirement
Plans for which MSDW Trust serves as Trustee or DWR's Retirement Plan Services
serves as recordkeeper pursuant to a written Recordkeeping Services Agreement:

     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 Qualified Retirement 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 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. It has been and remains the Fund's policy and practice
that, if checks for dividends or distributions paid in cash remain uncashed, no
interest will accrue on amounts represented by such uncashed checks.

   
     Targeted Dividends.SM 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 Morgan Stanley
Dean Witter Fund other than Morgan Stanley Dean Witter Developing Growth
Securities Trust or in another Class of Morgan Stanley 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 Morgan Stanley 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 Morgan Stanley Dean Witter
Fund the next business day. To participate in the Targeted Dividends program,
shareholders should contact their Morgan Stanley Dean Witter Financial Advisor
or other selected broker-dealer representative or the Transfer Agent.
Shareholders of the Fund must be shareholders of the selected Class of the
Morgan Stanley 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 Morgan Stanley Dean Witter Fund before entering
the program.

     EasyInvest.SM 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 Morgan Stanley 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 (subject to any applicable sales
charges). Shares of the Morgan Stanley Dean Witter money market funds redeemed
in connection with EasyInvest are redeemed on the business day preceding the
transfer of funds. For further information or to subscribe to EasyInvest,
shareholders should contact their Morgan Stanley Dean Witter Financial Advisor
or other selected broker-dealer representative 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


                                       27
<PAGE>

   
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 whose
shares of Morgan Stanley Dean Witter Funds have an aggregate value of $10,000
or more. Shares of any Fund from which redemptions will be made pursuant to the
Plan must have a value of $1,000 or more (referred to as a "SWP Fund"). The
required share values are determined on the date the shareholder establishes
the Withdrawal Plan. The Withdrawal Plan provides for monthly, quarterly,
semi-annual or annual payments in any amount not less than $25, or in any whole
percentage of the value of the SWP Funds' shares, on an annualized basis. Any
applicable Contingent Deferred Sales Charge ("CDSC") will be imposed on shares
redeemed under the Withdrawal Plan (see "Purchase of Fund Shares"), except that
the CDSC, if any, will be waived on redemptions under the Withdrawal Plan of up
to 12% annually of the value of each SWP Fund account, based on the share
values next determined after the shareholder establishes the Withdrawal Plan.
Redemptions for which this CDSC waiver policy applies may be in amounts up to
1% per month, 3% per quarter, 6% semi-annually or 12% annually. Under this CDSC
waiver policy, amount withdrawn each period will be paid by first redeeming
shares not subject to a CDSC because the shares were purchased by the
reinvestment of dividends or capital gains distributions, the CDSC period has
elapsed or some other waiver of the CDSC applies. If shares subject to a CDSC
must be redeemed, shares held for the longest period of time will be redeemed
first and continuing with shares held the next longest period of time until
shares held the shortest period of time are redeemed. 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, quarterly, semi-annual or annual
amount.

     A shareholder may suspend or terminate participation in the Withdrawal
Plan at any time. A shareholder who has suspended participation may resume
payments under the Withdrawal Plan, without requiring a new determination of
the account value for the 12% CDSC waiver. The Withdrawal Plan may be
terminated or revised at any time by the Fund.

     Prior to adding an additional SWP Fund to an existing Withdrawal Plan, the
required $10,000/$1,000 share values must be met, to be calculated on the date
the shareholder adds the additional SWP Fund. However, the addition of a new
SWP Fund will not change the account value for the 12% CDSC waiver for the SWP
Funds already participating in the Withdrawal Plan.

     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, quarter, or semi-annual or annual period and normally a
check for the proceeds will be mailed by the Transfer Agent, or amounts
credited to a shareholder's Dean Witter Reynolds Inc. or other selected
broker-dealer brokerage account, or amounts deposited electronically into the
shareholder's bank account via the Automated Clearing House, within five
business days after the date of redemption.

     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 a shareholder may make additional
investments while participating in the Withdrawal Plan, withdrawals made
concurrently with purchases of additional shares are inadvisable because of
sales charges applicable to purchases or redemptions of shares (see "Purchase
of Fund Shares" in the Prospectus).
    


                                       28
<PAGE>

   
     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 Morgan Stanley Dean Witter Financial Advisor or other selected
broker-dealer representative 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 Morgan Stanley 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
Morgan Stanley 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: Morgan Stanley Dean Witter Short-Term U.S. Treasury Trust, Morgan
Stanley Dean Witter Limited Term Municipal Trust, Morgan Stanley Dean Witter
Short-Term Bond Fund and five Morgan Stanley Dean Witter Funds which are money
market funds (the foregoing eight funds are hereinafter referred to as the
"Exchange Funds"). Class A shares may also be exchanged for shares of Morgan
Stanley Dean Witter Multi-State Municipal Series Trust and Morgan Stanley Dean
Witter Hawaii Municipal Trust, which are Morgan Stanley Dean Witter Funds sold
with a front-end sales charge ("FSC 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.
    

     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 Morgan Stanley
Dean Witter Multi-Class 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
    


                                       29
<PAGE>

   
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 Morgan Stanley Dean Witter Multi-Class 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
Morgan Stanley Dean Witter Multi-Class 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 Morgan Stanley Dean Witter Multi-Class
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
Morgan Stanley Dean Witter Multi-Class 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 Morgan Stanley Dean Witter
Multi-Class Fund are exchanged for shares of a Morgan Stanley Dean Witter
Multi-Class 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 Morgan Stanley 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 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.


                                       30
<PAGE>

     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 Morgan Stanley Dean
Witter Liquid Asset Fund Inc., Morgan Stanley Dean Witter Tax-Free Daily Income
Trust, Morgan Stanley Dean Witter California Tax-Free Daily Income Trust and
Morgan Stanley 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 Morgan Stanley 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 Morgan Stanley Dean Witter Special Value
Fund. The minimum initial investment for the Exchange Privilege account of each
Class of all other Morgan Stanley 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 Morgan Stanley 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 Morgan Stanley
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 Morgan Stanley Dean Witter Financial Advisor or other
selected broker-dealer representative 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. 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


                                       31
<PAGE>

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. 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). It has been and remains the
Fund's policy and practice that, if checks for redemption proceeds remain
uncashed, no interest will accrue on amounts represented by such uncashed
checks. Shareholders maintaining margin accounts with DWR or another selected
broker-dealer are referred to their Morgan Stanley Dean Witter Financial
Advisor or other selected broker-dealer representative regarding restrictions
on redemption of shares of the Fund pledged in the margin account.
    

     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.


                                       32
<PAGE>

     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. 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. The
Taxpayer Relief Act reduced the maximum tax rate on long-term capital gains
from 28% to 20%. It also lengthened the required holding period to obtain the
lower rate from more than twelve months to more than eighteen months. However,
the IRS Restructuring and Reform Act of 1998 reduced the holding period
requirement for the lower capital gain rate to more than twelve months for
transactions occurring after January 1, 1998. The lower rates do not apply to
collectibles and certain other assets. Additionally, the maximum capital gain
rate for assets that are held more than five years and that are acquired after
December 31, 2000 is 18%.
    

     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.

   
     Any loss realized by shareholders upon a redemption of shares within six
months of the date of their purchase will be treated as a long-term capital
loss to the extent of any distributions of net long-term capital gains during
the six-month period.
    

     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


                                       33
<PAGE>

   
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
within a 90-day period beginning 45 days before the ex-dividend date of each
qualifying dividend. Shareholders must meet a similar holding period
requirement with respect to their shares to claim the dividends received
deduction with respect to any distribution of qualifying dividends. 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.

     Shareholders are urged to consult their attorneys or tax advisors
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 Class B for
the one, five and ten year periods ended September 30, 1998 were --22.56%,
7.94% and 12.20%, respectively. The average annual total returns of Class A for
the fiscal year ended September 30, 1998 and for the period July 28, 1997
(inception of the Class) through September 30, 1998 were --22.55% and --11.61%,
respectively. The average annual total returns of Class C for the fiscal year
ended September 30, 1998 and for the period July 28, 1997 (inception of the
Class) through September 30, 1998 were --19.61% and --8.17%, respectively. The
average annual total returns of Class D for the fiscal year ended September 30,
1998 and for the period July 28, 1997 (inception of the Class) through
September 30, 1998 were --18.05% and --7.23%, respectively.

     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 Class B for the
one, five and ten year periods ended September 30, 1998 were --18.88%, 8.23%
and 12.20%, respectively. Based on this calculation, the average annual total
returns of Class A for the fiscal year ended September 30, 1998 and for the
period July 28, 1997 through September 30, 1998 were --18.26% and --7.45%,
respectively, the average annual total returns of Class C for the fiscal year
ended September 30, 1998 and for the period July 28, 1997 through September 30,
1998 were --18.88% and --8.17%, respectively, and the average annual total
returns of Class D for the fiscal year ended September 30, 1998 and for the
period July 28, 1997 through September 30, 1998 were --18.05% and --7.23%,
respectively.
    

     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


                                       34
<PAGE>

   
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 total returns for Class B for
the year ended September 30, 1998, for the five-year period ended September 30,
1998 and for the ten-year period ended September 30, 1998 were --18.88%, 48.49%
and 216.24%, respectively. Based on the foregoing calculations, the total
returns for Class A for the fiscal year ended September 30, 1998 and for the
period July 28, 1997 through September 30, 1998 were --18.26% and --8.70%,
respectively, the total returns of Class C for the fiscal year ended September
30, 1998 and for the period July 28, 1997 through September 30, 1998 were
- --18.88% and --9.52%, respectively, and the total returns of Class D for the
fiscal year ended September 30, 1998 and for the period July 28, 1997 through
September 30, 1998 were --18.05% and --8.44%, respectively.

     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 each Class at
inception of the Class would have grown (or declined) to the following amounts
at September 30, 1998:

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.
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.


                                       35

MORGAN STANLEY DEAN WITTER DEVELOPING GROWTH SECURITIES TRUST
NOTES TO FINANCIAL STATEMENTS September 30, 1998

1. ORGANIZATION AND ACCOUNTING POLICIES

Morgan Stanley Dean Witter Developing Growth Securities Trust (the "Fund"),
formerly Dean Witter Developing Growth Securities Trust, 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. On July
28, 1997, the Fund commenced offering three additional classes of shares, with
the then current shares designated as Class B shares.

The Fund offers Class A shares, Class B shares, Class C shares and Class D
shares. The four classes are substantially the same except that most Class A
shares are subject to a sales charge imposed at the time of purchase and some
Class A shares, and most Class B shares and Class C shares are subject to a
contingent deferred sales charge imposed on shares redeemed within one year,
six years and one year, respectively. Class D shares are not subject to a sales
charge. Additionally, Class A shares, Class B shares and Class C shares incur
distribution expenses.

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 Morgan Stanley Dean
Witter Advisors Inc. (the "Investment Manager"), formerly Dean Witter
InterCapital Inc., 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.

MORGAN STANLEY DEAN WITTER DEVELOPING GROWTH SECURITIES TRUST
NOTES TO FINANCIAL STATEMENTS September 30, 1998, continued

   
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. MULTIPLE CLASS ALLOCATIONS -- Investment income, expenses (other than
distribution fees), and realized and unrealized gains and losses are allocated
to each class of shares based upon the relative net asset value on the date
such items are recognized. Distribution fees are charged directly to the
respective class.

D. 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.

E. 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 Morgan Stanley 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. The Plan provides that the Fund will pay the Distributor a fee which is
accrued daily and paid monthly at the following annual rates: (i) Class A - up
to 0.25% of the average daily net assets of Class A; (ii) Class B - 1.0% of the
lesser of: (a) the average daily aggregate gross sales of the Class B shares
since the inception of the Fund (not including reinvestment of dividend or
capital gain distributions) less the average daily aggregate net asset value of
the Class B shares redeemed since the Fund's inception upon which a contingent
deferred sales charge has been imposed or waived; or (b) the average daily net
assets of Class B; and (iii) Class C - up to 1.0% of the average daily net
assets of
Class C. In the case of Class A shares, amounts paid under the Plan are paid to
the Distributor for services provided. In the case of Class B and Class C
shares, amounts paid under the Plan are paid to the Distributor for (1)
services provided and the expenses borne by it and others in the distribution
of the shares of these Classes, including the payment of commissions for sales
of these Classes and incentive compensation to, and expenses of, Morgan Stanley
Dean Witter Financial Advisors and others who engage in or support distribution
of the shares or who service shareholder accounts, including overhead and
telephone expenses; (2) printing and distribution of prospectuses and reports
used in connection with the offering of these shares to other than current
shareholders; and (3) 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
Dean Witter Reynolds Inc. ("DWR"), an affiliate of the Investment Manager and
Distributor, 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.

In the case of Class B shares, provided that the Plan continues in effect, any
cumulative expenses incurred by the Distributor but not yet recovered may be
recovered through the payment of future distribution fees from the Fund
pursuant to the Plan and contingent deferred sales charges paid by investors
upon redemption of Class B shares. 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 $24,581,350 at September 30, 1998.

In the case of Class A shares 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 credit to Morgan Stanley Dean Witter Financial Advisors or other
selected broker-dealer representatives may be reimbursed in the subsequent
calendar year. For the year ended September 30, 1998, the distribution fee was
accrued for Class A shares and Class C shares at the annual rate of 0.25% and
1.0%, respectively.

The Distributor has informed the Fund that for the year ended September 30,
1998, it received contingent deferred sales charges from certain redemptions of
the Fund's Class A shares, Class B shares and Class C shares of $40, $1,202,521
and $2,697, respectively, and received $56,314, in front-end sales charges from
sales of the Fund's Class A shares. The respective shareholders pay such
charges which are not an expense of the Fund.

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, 1998
aggregated $1,293,443,813, and $1,487,259,823, respectively.

For the year ended September 30, 1998, the Fund incurred $100,032 in brokerage
commissions with DWR for portfolio transactions executed on behalf of the Fund.

Co., Inc., of $2,785,935 and $1,589,947, respectively.

Morgan Stanley Dean Witter Trust FSB, an affiliate of the Investment Manager
and Distributor, is the Fund's transfer agent. At September 30, 1998, the Fund
had transfer agent fees and expenses payable of approximately $8,000.

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

MORGAN STANLEY DEAN WITTER DEVELOPING GROWTH SECURITIES TRUST
REPORT OF INDEPENDENT ACCOUNTANTS


TO THE SHAREHOLDERS AND TRUSTEES
OF MORGAN STANLEY 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 Morgan Stanley Dean Witter
Developing Growth Securities Trust (the "Fund"), formerly Dean Witter
Developing Growth Securities Trust, at September 30, 1998, 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 periods presented, 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, 1998 by correspondence with the
custodian and brokers, provide a reasonable basis for the opinion expressed
above.

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 

                                       2
<PAGE>

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.

      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.

         WHEREAS, the Trust was established by the Declaration on the date

              and the Trust may hold its property and conduct its activities
              under such other name."

         2. Subsection (n) of Section 1.2 of Article I of the Declaration is
hereby amended so that that subsection shall read in its entirety as follows:

              "Section 1.2. Definitions...

              "(n) "Trust" means the Morgan Stanley Dean Witter Developing
              Growth Securities Trust."

         3. Section 11.7 of Article XI of the Declaration is hereby amended so
that that section shall read as follows:

              "Section 11.7. Use of the name "Morgan Stanley Dean Witter."
              Morgan Stanley Dean Witter & Co. ("MSDW") has consented to the
              use by the Trust of the identifying name "Morgan Stanley Dean
              Witter," which is a property right of MSDW. The Trust will only
              use 

<PAGE>

              the name "Morgan Stanley Dean Witter" as a component of its name
              and for no other purpose, and will not purport to grant to any
              third party the right to use the name "Morgan Stanley Dean
              Witter" for any purpose. MSDW, or any corporate affiliate of
              MSDW, may use or grant to others the right to use the name
              "Morgan Stanley Dean Witter," or any combination or abbreviation
              thereof, as all or a portion of a corporate or business name or
              for any commercial purpose, including a grant of such right to
              any other investment company. At the request of MSDW or any
              corporate affiliate of MSDW, the Trust will take such action as
              may be required to provide its consent to the use of the name
              "Morgan Stanley Dean Witter," or any combination or abbreviation
              thereof, by MSDW or any corporate affiliate of MSDW, or by any
              person to whom MSDW or a corporate affiliate of MSDW shall have
              granted the right to such use. Upon the termination of any
              investment advisory agreement into which a corporate affiliate of
              MSDW and the Trust may enter, the Trust shall, upon request of
              MSDW or any corporate affiliate of MSDW, cease to use the name
              "Morgan Stanley Dean Witter" as a component of its name, and
              shall not use the name, or any combination or abbreviation
              thereof, as part of its name or for any other commercial purpose,
              and shall cause its officers, Trustees and Shareholders to take
              any and all actions which MSDW or any corporate affiliate of MSDW
              may request to effect the foregoing and to reconvey to MSDW any
              and all rights to such name."

         4. The Trustees of the Trust hereby reaffirm the Declaration, as
amended, in all respects.

         5. This Amendment may be executed in more than one counterpart, each
of which shall be deemed an original, but all of which together shall
constitute one and the same document.

                        INVESTMENT MANAGEMENT AGREEMENT
 
    AGREEMENT made as of the 31st day of May, 1997, and amended as of April 30,
1998, 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 who are also directors, officers or employees of
the Investment Manager, and provide such office space, facilities and equipment
and such clerical help and

<PAGE>

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 use the name "Dean
Witter" for any purpose, (iii) the Investment Manager or its parent, Morgan
Stanley Dean Witter & Co., or any corporate affiliate of the Investment
Manager's parent, may use or grant to others the right to use the name "Dean
 
                                       3
<PAGE>

Witter," or any combination or abbreviation thereof, as all or a portion of a
corporate or business name or for any commercial purpose, including a grant of
such right to any other investment company, (iv) at the request of the
Investment Manager or its parent, the Fund will take such action as may be
required to provide its consent to the use of the name "Dean Witter," or any
combination or abbreviation thereof, by the Investment Manager or its parent or
any corporate affiliate of the Investment Manager's parent, or by any person to
whom the Investment Manager or its parent or any corporate affiliate of the
Investment Manager's parent shall have granted the right to such use, and (v)
upon the termination of any investment advisory agreement into which the
Investment Manager and the Fund may enter, or upon termination of affiliation of
the Investment Manager with its parent, the Fund shall, upon request by the
Investment Manager or its parent, cease to use the name "Dean Witter" as a
component of its name, and shall not use the name, or any combination or
abbreviation thereof, as a part of its name or for any other commercial purpose,
and shall cause its officers, Trustees and shareholders to take any and all
actions which the Investment Manager or its parent may request to effect the
foregoing and to reconvey to the Investment Manager or its parent any and all
rights to such name.
 
    14. 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 the 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.
 
    IN WITNESS WHEREOF, the parties hereto have executed and delivered this
Agreement, as amended, on April 30, 1998 in New York, New York.

                        MORGAN STANLEY DEAN WITTER FUNDS

                             DISTRIBUTION AGREEMENT

     AGREEMENT made as of this 28th day of July, 1997, and amended as of June
22, 1998, between each of the open-end investment companies to which Morgan
Stanley Dean Witter Advisors 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 Morgan Stanley 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

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 Financial Advisors,
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 remain in force until April 30, 1999, 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.

                                       6
<PAGE>

     SECTION 14. Personal Liability. With respect to any Fund that is organized
as an unincorporated business trust under the laws of the Commonwealth of
Massachusetts, its Declaration of the Trust (each, a "Declaration") is on file
in the office of the Secretary of the Commonwealth of Massachusetts. Each
Declaration provides that the name of the Fund 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 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 amended, on June 22, 1998 in New York, New York.

                 MORGAN STANLEY DEAN WITTER DISTRIBUTORS INC.
                       OMNIBUS SELECTED DEALER AGREEMENT

Dear Sir or Madam:

     We, Morgan Stanley Dean Witter Distributors Inc. (the "Distributor") have
a distribution agreement (the "Distribution Agreement") with each of the
open-end investment companies listed in Schedule A attached hereto (each, a
"Fund"), pursuant to which we act as the Distributor for the sale of each
Fund's shares of common stock or beneficial interest, as the case may be, (the
"Shares"). Under the Distribution Agreement, we have the right to distribute
Shares for resale.

     Each Fund is an open-end management investment company registered under
the Investment Company Act of 1940, as amended, and the Shares being offered to
the public are registered under the Securities Act of 1933, as amended (the
"Securities Act"). You have received a copy of the Distribution Agreements
between us and each Fund and reference is made herein to certain provisions of
such Distribution Agreements. The terms used herein, including "Prospectus" and
"Registration Statement" of each Fund and "Selected Dealer" shall have the same
meaning in this Agreement as in the Distribution Agreements. As principal, we
offer to sell Shares to your customers, upon the following terms and
conditions:

     1. In all sales of Shares to the public you shall act on behalf of your
customers which for purposes of this Agreement are limited to customers for
which Nations Banc Investments, Inc. is the Introducing Broker, and in no
transaction shall you have any authority to act as agent for a Fund, for us or
for any Selected Dealer.

     2. Orders received from you will be accepted through us or on our behalf
only at the public offering price applicable to each order, as set forth in the
applicable current Prospectus. The procedure relating to the handling of orders
shall be subject to written instructions which we or the applicable Fund shall
forward from time to time to you. All orders are subject to acceptance or
rejection by us or a Fund in the sole discretion of either. The Distributor of
the Fund will promptly notify you in writing of any such rejection.

     3. You shall not place orders for any Shares unless you have already
received purchase orders for such Shares at the applicable public offering
price and subject to the terms hereof and of the applicable Distribution
Agreement and Prospectus. In connection herewith, you agree to abide by the
terms of the applicable Distribution Agreement and Prospectus to the extent
required hereunder. Furthermore, you agree that (i) you will offer or sell any
of the Shares only under circumstances that will result in compliance with all
applicable Federal and state securities laws; (ii) you will not furnish or
cause to be furnished to any person any information relating to the Shares
which is inconsistent in any respect with the information contained in the
applicable Prospectus (as then amended or supplemented) or cause any
advertisements to be published by radio or television or in any newspaper or
posted in any public place or use any sales promotional material without our
consent and the consent of the applicable Fund; and (iii) you will endeavor to
obtain proxies from purchasers of Shares. You also agree that you will be
liable to Distributor for payment of the purchase price for Shares purchased by
customers and that you shall make payment for such shares when due.

     4. We will compensate you for sales of shares of the Funds and personal
services to Fund shareholders by paying you a sales charge and/or other
commission (which may be in the form of a gross sales credit and/or an annual
residual commission) and/or a service fee, each as separately agreed by you and
us with respect to each Fund.

     5. If any Shares sold to your customers under the terms of this Agreement
are repurchased by us for the account of a Fund or are tendered for redemption
within seven business days after the date of the confirmation of the original
purchase by you, it is agreed that you shall forfeit your right to, and refund
to us, any commission received by you with respect to such Shares.

     6. No person is authorized to make any representations concerning the
Shares or the Funds except those contained in the current applicable Prospectus
and in such printed information subsequently issued


                                       1
<PAGE>

by us or a Fund as information supplemental to such Prospectus. In selling
Shares, you shall rely solely on the representations contained in the
applicable Prospectus and supplemental information mentioned above. Any printed
information which we furnish you other than the Prospectus and the Funds'
periodic reports and proxy solicitation materials are our sole responsibility
and not the responsibility of the Funds, and you agree that the Funds shall
have no liability or responsibility to you in these respects unless expressly
assumed in connection therewith.

     7. You are hereby authorized (i) to place orders directly with a Fund or
its agent for shares of the Fund to be sold by us subject to the applicable
terms and conditions governing the placement of orders for the purchase of Fund
Shares, as set forth in the Distribution Agreement, and (ii) to tender Shares
directly to the Fund or its agent for redemption subject to the applicable
terms and conditions set forth in the Distribution Agreement. We will provide
you with copies of any updates to the Distribution Agreement.

     8. We reserve the right in our discretion, without notice, to suspend
sales or withdraw the offering of Shares entirely. Each party hereto has the
right to cancel this agreement with respect to one or more Funds upon fifteen
days prior written notice to the other party.

     9. I. You shall indemnify and hold us harmless from and against any and
all losses, costs, (including reasonable attorney's fees) claims, damages and
liabilities which arise as a result of action taken pursuant to instructions
from you, or on your behalf to: (a)(i) place orders for Shares of a Fund with
the Fund's transfer agent or direct the transfer agent to receive instructions
for the order of Shares, and (ii) accept monies or direct that the transfer
agent accept monies as payment for the order of such Shares, all as
contemplated by and in accordance with Section 3 of the applicable Distribution
Agreement; (b)(i) place orders for the redemption of Shares of a Fund with the
Fund's transfer agent or direct the transfer agent to receive instruction for
the redemption of such Shares and (ii) to pay redemption proceeds or to direct
that the transfer agent pay redemption proceeds in connection with orders for
the redemption of Shares, all as contemplated by and in accordance with Section
4 of the applicable Distribution Agreement; Distributor agrees to indemnify and
hold harmless you and your affiliates, officers, directors, control persons and
employees from and against any and all losses, costs (including reasonable
attorney's fees), claims, damages and liabilities which arise as a result of
Distributor's failure to fulfill its obligations hereunder and from any alleged
inaccuracy, omission or misrepresentation contained in any prospectus or any
advertising, or sales literature prepared by Distributor or the Fund provided,
however, that in no case, (i) is this indemnity in favor of you or us and any
of other party's such controlling persons to be deemed to protect us or any
such controlling persons against any liability to which we or any such
controlling persons would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence in the performance of our duties or
by reason of reckless disregard of our obligations and duties under this
Agreement or the applicable Distribution Agreement; or (ii) are you to be
liable under the indemnity agreement contained in this paragraph with respect
to any claim made against us or any such controlling persons, unless we or any
such controlling persons, as the case may be, shall have notified you 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 us or
such controlling persons (or after we or such controlling persons shall have
received notice of such service on any designated agent), notwithstanding the
failure to notify you of any such claim shall not relieve you from any
liability which you may have to the person against whom such action is brought
otherwise than on account of the indemnity agreement contained in this
paragraph.

     II. You will be entitled to participate at your own expense in the
defense, or, if you so elect, to assume the defense, of any suit brought to
enforce any such liability, but if you elect to assume the defense, such
defense shall be conducted by counsel chosen by you and reasonably satisfactory
to us or such controlling person or persons, defendant or defendants in the
suit. In the event you elect to assume the defense of any such suit and retain
such counsel, we 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 you do not elect to assume the defense of any
such suit, you will reimburse us 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 party shall promptly notify the other party
to this Agreement of the commencement of any litigation or proceedings against
it or any of its officers or directors in connection with the issuance or sale
of the Shares pursuant to this Agreement.


                                       2

     III. If the indemnification provided for in this Section 9 is unavailable
or insufficient to hold harmless the Distributor, as provided above in respect
of any losses, claims, damages, liabilities or expenses (or actions in respect
thereof) referred to herein, then you shall contribute to the amount paid or
payable by us 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 you on the one hand and us 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 you
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 your relative fault on the one hand and our relative fault on the
other, in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or expenses (or actions in respect
thereof), as well as any other relevant equitable considerations. You and we
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 us 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 us in connection
with investigating or defending any such claim. Notwithstanding the provisions
of this subsection (III), you shall not be required to contribute any amount in
excess of the amount by which the total price at which the Shares distributed
by you to the public were offered to the public exceeds the amount of any
damages which you have 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
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

     IV. Notwithstanding the provisions of subsections (I), (II) and (III), we
shall indemnify, defend and hold harmless you and your officers, directors,
employees, affiliates, agents, successors and assigns from and against any and
all claims and all related losses, expenses, damages, cost and liabilities
including reasonable attorneys' fees and expenses incurred in investigation or
defense, arising out of or related to any breach of any representation,
warranty or covenant by us contained in Section 15 of this Agreement.

     11. We shall have full authority to take such action as we may deem
advisable in respect of all matters pertaining to the distribution and
redemption of Shares. Neither party shall be under any liability to the other
party except for lack of good faith and for obligations expressly assumed
herein. Nothing contained in this paragraph is intended to operate as, and the
provisions of this paragraph shall not in any way whatsoever constitute, a
waiver by you of compliance with any provision of the Securities Act, or of the
rules and regulations of the Securities and Exchange Commission issued
thereunder.

     12. Each party represents that it is a member in good standing of the
National Association of Securities Dealers, Inc. and, with respect to any sales
in the United States, each party hereby agrees to abide by the Rules of Fair
Practice of such Association relating to the performance of the obligations
hereunder.

     13. We will inform you in writing as to the states in which we believe the
Shares have been qualified for sale under, or are exempt from the requirements
of, the respective securities laws of such states, but we assume no
responsibility or obligation as to your right to sell Shares in any
jurisdiction.

     14. Notwithstanding any other provision of this Agreement to the contrary,
we represent and warrant that the names and addresses of your customers (or
customers of your affiliates) which have or which may come to our attention in
connection with this Agreement are confidential and are your exclusive property
and shall not be utilized by us except in connection with the functions
performed by us in connection with this Agreement. Notwithstanding the
foregoing, should a customer request, that we or an organization affiliated
with us, provide services to such customer, we or such affiliated organization
shall in no way violate this representation and warranty, nor be considered in
breach of this Agreement.

     15. We represent, warrant, and covenant to you that the marketing
materials, any communications distributed to the public and training materials
designed by us or our agents relating to the product sold under this Agreement
are true and accurate and do not omit to state a fact necessary to make the
information contained therein not misleading and comply with applicable federal
and state laws. We


                                       3
<PAGE>

further represent, warrant, and covenant to you that the performance by us of
our obligations under this Agreement in no way constitutes an infringement on
or other violation of copyright, trade secret, trademark, proprietary
information or non-disclosure rights of any other party.

     16. We shall maintain a contingency disaster recovery plan, and, in the
event you are so required by any regulatory or governmental agency, we shall
make such plan available to you for inspection at your office upon reasonable
advance notice by you. Each party agrees that it will at all times conduct its
activities under this Agreement in an equitable, legal and professional manner.

     17. We understand that the performance of your and our obligations under
this Agreement is subject to examination during business hours by your
authorized representatives and auditors and by federal and state regulatory
agencies, and we agree that upon being given reasonable notice and proper
identification we shall submit or furnish at a reasonable time and place to any
such representative or regulatory agency reports, information, or other data
relating to this Agreement as may reasonably be required or requested by you.
We shall maintain and make available to you upon reasonable notice all
material, data, files, and records relating to this Agreement for a period of
not less than three years after the termination of this Agreement.

     18. The sales, advertising and promotional materials designed by either
party or its agents relating to products sold under this Agreement shall comply
with applicable federal and state laws. Each party agrees that the sales,
advertising and promotional materials shall be made available to the other
party prior to distribution to your employees or customers.

     19. Any controversy or claim between or among the parties hereto arising
out of or relating to this Agreement, including any claim based on or arising
from an alleged tort, shall be determined by binding arbitration in accordance
with the rules of the National Association of Securities Dealers, Inc. Judgment
upon any arbitration award may be entered in any court having jurisdiction. Any
party to this Agreement may bring an action, including a summary or expedited
proceeding, to compel arbitration of any controversy or claim to which this
Agreement applies in any court having jurisdiction over such action.

     20. All notices or other communications under this Agreement shall be in
writing and given as follows:

         NOW THEREFORE, in consideration of the mutual covenants herein
contained, the parties hereto agree as follows:

Article 1  Terms of Appointment; Duties of MSDW TRUST

           1.1 Subject to the terms and conditions set forth in this Agreement,

Fund, whether now or hereafter authorized or issued ("Shares"), dividend
disbursing agent and shareholder servicing agent in

Fund agrees to pay MSDW TRUST an annual maintenance fee for each Shareholder
account and certain transactional fees, if applicable, as set out in the
respective fee schedule attached hereto as Schedule A. Such fees and
out-of-pocket expenses and advances identified under Section 2.2 below may be

                               SERVICES AGREEMENT

     AGREEMENT made as of the 17th day of April, 1995, and amended as of June
22, 1998, by and between Morgan Stanley Dean Witter Advisors Inc., a Delaware
corporation (herein referred to as "MSDW Advisors"), and Morgan Stanley Dean
Witter Services Company Inc., a Delaware corporation (herein referred to as
"MSDW Services").

     WHEREAS, MSDW Advisors has entered into separate agreements (each such
agreement being herein referred to as an "Investment Management Agreement")
with certain investment companies as set forth on Schedule A (each such
investment company being herein referred to as a "Fund" and, collectively, as
the "Funds") pursuant to which MSDW Advisors is to perform, or supervise the
performance of, among other services, administrative services for the Funds
(and, in the case of Funds with multiple portfolios, the Series or Portfolios
of the Funds (such Series and Portfolio being herein individually referred to
as "a Series" and, collectively, as "the Series"));

     WHEREAS, MSDW Advisors desires to retain MSDW Services to perform the
administrative services as described below; and

     WHEREAS, MSDW Services desires to be retained by MSDW Advisors to perform
such administrative services:

     Now, therefore, in consideration of the mutual covenants and agreements of
the parties hereto as herein set forth, the parties covenant and agree as
follows:

     1. MSDW Services agrees to provide administrative services to each Fund as
hereinafter set forth. Without limiting the generality of the foregoing, MSDW
Services shall (i) administer the Fund's business affairs and supervise the
overall day-to-day operations of the Fund (other than rendering investment
advice); (ii) provide the Fund with full administrative services, including the
maintenance of certain books and records, such as journals, ledger accounts and
other records required under the Investment Company Act of 1940, as amended
(the "Act"), the notification to the Fund and MSDW Advisors of available funds
for investment, the reconciliation of account information and balances among
the Fund's custodian, transfer agent and dividend disbursing agent and MSDW
Advisors, and the calculation of the net asset value of the Fund's shares;
(iii) provide the Fund with the services of persons competent to perform such
supervisory, administrative and clerical functions as are necessary to provide
effective operation of the Fund; (iv) oversee the performance of administrative
and professional services rendered to the Fund by others, including its
custodian, transfer agent and dividend disbursing agent, as well as accounting,
auditing and other services; (v) provide the Fund with adequate general office
space and facilities; (vi) assist in the preparation and the printing of the
periodic updating of the Fund's registration statement and prospectus (and, in
the case of an open-end Fund, the statement of additional information), tax
returns, proxy statements, and reports to its shareholders and the Securities
and Exchange Commission; and (vii) monitor the compliance of the Fund's
investment policies and restrictions.

     In the event that MSDW Advisors enters into an Investment Management
Agreement with another investment company, and wishes to retain MSDW Services
to perform administrative services hereunder, it shall notify MSDW Services in
writing. If MSDW Services is willing to render such services, it shall notify
MSDW Advisors in writing, whereupon such other Fund shall become a Fund as
defined herein.

     2. MSDW Services 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 MSDW Services shall be deemed to include
officers of MSDW Services and persons employed or otherwise retained by MSDW
Services (including officers and employees of MSDW Advisors, with the consent
of MSDW Advisors) to furnish services, statistical and other factual data,
information with respect to technical and scientific developments, and such
other information, advice and assistance as MSDW Services may desire. MSDW
Services shall maintain each 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, MSDW Services shall surrender to MSDW
Advisors or to the Fund such of the books and records so requested.

                                       1

     3.  MSDW Advisors will, from time to time, furnish or otherwise make
available to MSDW Services such financial reports, proxy statements and other
information relating to the business and affairs of the Fund as MSDW Services
may reasonably require in order to discharge its duties and obligations to the
Fund under this Agreement or to comply with any applicable law and regulation
or request of the Board of Directors/Trustees of the Fund.

     4. For the services to be rendered, the facilities furnished, and the
expenses assumed by MSDW Services, MSDW Advisors shall pay to MSDW Services
monthly compensation calculated daily (in the case of an open-end Fund) or
weekly (in the case of a closed-end Fund) by applying the annual rate or rates
set forth on Schedule B to the net assets of each Fund. Except as hereinafter
set forth, (i) in the case of an open-end Fund, compensation under this
Agreement shall be calculated by applying 1/365th of the annual rate or rates
to the Fund's or the Series' daily net assets determined as of the close of
business on that day or the last previous business day and (ii) in the case of
a closed-end Fund, compensation under this Agreement shall be calculated by
applying the annual rate or rates to the Fund's average weekly net assets
determined as of the close of the last business day of each week. 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 on Schedule B. Subject to the
provisions of paragraph 5 hereof, payment of MSDW Services' compensation for
the preceding month shall be made as promptly as possible after completion of
the computations contemplated by paragraph 5 hereof.

     5. In the event the operating expenses of any open-end Fund and/or any
Series thereof, or of InterCapital Income Securities Inc., including amounts
payable to MSDW Advisors pursuant to the Investment Management Agreement, for
any fiscal year ending on a date on which this Agreement is in effect, exceed
the expense limitations applicable to the Fund and/or any Series thereof
imposed by state securities laws or regulations thereunder, as such limitations
may be raised or lowered from time to time, or, in the case of InterCapital
Income Securities Inc. or Morgan Stanley Dean Witter Variable Investment Series
or any Series thereof, the expense limitation specified in the Fund's
Investment Management Agreement, the fee payable hereunder shall be reduced on
a pro rata basis in the same proportion as the fee payable by the Fund under
the Investment Management Agreement is reduced.

     6. MSDW Services shall bear the cost of rendering the administrative
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 employed by MSDW Services, and such clerical help and bookkeeping services
as MSDW Services shall reasonably require in performing its duties hereunder.

     7. MSDW Services will use its best efforts in the performance of
administrative activitives on behalf of each Fund, but in the absence of
willful misfeasance, bad faith, gross negligence or reckless disregard of its
obligations hereunder, MSDW Services 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 MSDW Services or for any losses sustained by the Fund or its
investors. It is understood that, subject to the terms and conditions of the
Investment Management Agreement between each Fund and MSDW Advisors, MSDW
Advisors shall retain ultimate responsibility for all services to be performed
hereunder by MSDW Services. MSDW Services shall indemnify MSDW Advisors and
hold it harmless from any liability that MSDW Advisors may incur arising out of
any act or failure to act by MSDW Services in carrying out its responsibilities
hereunder.

     8. It is understood that any of the shareholders, Directors/Trustees,
officers and employees of the Fund may be a shareholder, director, officer or
employee of, or be otherwise interested in, MSDW Services, and in any person
controlling, controlled by or under common control with MSDW Services, and that
MSDW Services and any person controlling, controlled by or under common control
with MSDW Services may have an interest in the Fund. It is also understood that
MSDW Services and any affiliated persons thereof or any persons controlling,
controlled by or under common control with MSDW Services have and may have
advisory, management, administration service or other contracts with other
organizations and persons, and may have other interests and businesses, and
further may purchase, sell or trade any securities or commodities for their own
accounts or for the account of others for whom they may be acting.

                                       2

     9. This Agreement shall continue until April 30, 1999, and thereafter
shall continue automatically for successive periods of one year unless
terminated by either party by written notice delivered to the other party
within 30 days of the expiration of the then-existing period. Notwithstanding
the foregoing, this Agreement may be terminated at any time, by either party on
30 days' written notice delivered to the other party. In the event that the
Investment Management Agreement between any Fund and MSDW Advisors is
terminated, this Agreement will automatically terminate with respect to such
Fund.

by written agreement executed by each of the parties hereto.

consent of the other party.

                       MORGAN STANLEY DEAN WITTER FUNDS
                              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"), effective as of
July 28, 1997, and amended as of June 22, 1998. The Plan relates to shares of
the open-end investment companies to which Morgan Stanley Dean Witter Advisors
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 Morgan Stanley 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 (Morgan Stanley Dean Witter American Value Fund, Morgan
Stanley Dean Witter Natural Resource Development Securities Inc., Morgan
Stanley Dean Witter

                                       1
<PAGE>

Strategist Fund and Morgan Stanley Dean Witter Dividend Growth Securities
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 Morgan Stanley 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

- --------------
(1)  The payments under the 12b-1 Plan for each of Morgan Stanley Dean Witter
     American Value Fund, Morgan Stanley Dean Witter Natural Resource
     Development Securities Inc. and Morgan Stanley 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 Morgan
     Stanley 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>

in share value due to capital appreciation and shares acquired through the
reinvestment of dividends or 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 Morgan Stanley Dean Witter Balanced Growth Fund and Morgan Stanley 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 Morgan Stanley Dean
Witter American Value Fund purchased prior to April 30, 1984, shares of Morgan
Stanley Dean Witter Strategist Fund purchased prior to November 8, 1989 and
shares of Morgan Stanley Dean Witter Natural Resource Development Securities
Inc. and Morgan Stanley 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 Morgan Stanley Dean Witter Balanced Growth Fund and Morgan Stanley
Dean Witter Balanced Income Fund held prior to July 28, 1997 have been
designated Class C shares except that shares of Morgan Stanley Dean Witter
Balanced Growth Fund and Morgan Stanley 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 were purchased before July 28, 1997
by trusts for which Dean Witter Trust FSB ("MSDW Trust") provides discretionary
trustee services converted to Class A shares on August 29, 1997 (the CDSC was
not 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 plan
qualified under Section 401(a) of the Internal Revenue Code (the "Code") and
for which MSDW Trust serves as Trustee or DWR's Retirement Plan Services serves
as recordkeeper pursuant to a written Recordkeeping Services Agreement, all
Class B

                                       3
<PAGE>

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 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.
