                         NOVEMBER 25, 1998

                         Morgan Stanley Dean Witter Income Builder Fund (the
"Fund") is an open-end, diversified management investment company whose primary
investment objective is to seek reasonable income. Growth of capital is the
secondary objective. The Fund seeks to achieve its objectives by investing,
under normal market conditions, at least 65% of its total assets in a
diversified portfolio of income-producing equity securities, including common
stock, preferred stock and convertible securities. Up to 35% of the Fund's
assets may be invested in fixed-income securities or common stocks that do not
pay a regular dividend but are expected to contribute to the Fund's ability to
meet its investment objectives.
    


   
                         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

- --------------------------------------------------------------------------------------------------------------------------
Distributor and     Morgan Stanley Dean Witter Distributors Inc. is the Distributor of the Fund's shares. The Fund has
Distribution        adopted a distribution plan pursuant to Rule 12b-1 under the Investment Company Act (the "12b-1

                    Fund to the Distributor. The entire 12b-1 fee payable by Class A and a portion of the 12b-1 fee
                    payable by each of Class B and Class C equal to 0.25% of the average daily net assets of the
                    Class are currently each characterized as a service fee within the meaning of the National
                    Association of Securities Dealers, Inc. guidelines. The remaining portion of the 12b-1 fee, if any,
                    is characterized as an asset-based sales charge (see pages 18 and 27).
- --------------------------------------------------------------------------------------------------------------------------
Alternative         Four classes of shares are offered:
Purchase
Arrangements        o  Class A shares are offered with a front-end sales charge, starting at 5.25% and reduced for
                    larger purchases. Investments of $1 million or more (and investments by certain other limited
                    categories of investors) are not subject to any sales charge at the time of purchase but a
                    contingent deferred sales charge ("CDSC") of 1.0% may be imposed on redemptions within one
                    year of purchase. The Fund is authorized to reimburse the Distributor for specific expenses
                    incurred in promoting the distribution of the Fund's Class A shares and servicing shareholder
                    accounts pursuant to the Fund's 12b-1 Plan. Reimbursement may in no event exceed an amount
                    equal to payments at an annual rate of 0.25% of average daily net assets of the Class (see pages
                    18, 22 and 27).

                   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
                   that have been designated Class B shares 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 18, 24 and 27).

                   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 18, 26 and 27).

                   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
                   fees (see pages 18, 26 and 27).
- --------------------------------------------------------------------------------------------------------------------------
Dividends and      The Fund pays quarterly income dividends and distributes substantially all of any net short-term
Capital Gains      and net long-term capital gains at least once each year. The Fund may, however, determine to
Distributions      retain all or part of any net long-term capital gains in any year for reinvestment. Dividends and
                   capital gains distributions paid on shares of a Class are automatically reinvested in additional
                   shares of the same Class at net asset value unless the shareholder elects to receive cash. Shares
                   acquired by dividend and distribution reinvestment will not be subject to any sales charge or
                   CDSC (see pages 29 and 33).
- --------------------------------------------------------------------------------------------------------------------------
Redemption         Shares are redeemable by the shareholder at net asset value less any applicable CDSC on Class
                   A, Class B or Class C shares. An account may be involuntarily redeemed if the total value of the
                   account is less than $100 or, if the account was opened through EasyInvestSM, if after twelve
                   months the shareholder has invested less than $1,000 in the account (see page 32).
- --------------------------------------------------------------------------------------------------------------------------
Risk               The net asset value of the Fund's shares will fluctuate with changes in market value of portfolio
Considerations     securities. Dividends payable by the Fund will vary in relation to the amounts of dividends earned
                   on common stock and interest earned on fixed-income securities. The value of the Fund's
                   convertible and fixed-income portfolio securities and, therefore, the Fund's net asset value per
                   share, may increase or decrease due to various factors, including changes in prevailing interest
                   rates. Generally, a rise in interest rates will result in a decrease in the Fund's net asset value per
                   share, while a drop in interest rates will result in an increase in the Fund's net asset value per
                   share. The high yield, high risk fixed-income securities in which the Fund may invest are subject
                   to greater risk of loss of income and principal than higher rated, lower yielding fixed-income
                   securities. The prices of high yield, high risk securities have been found to be less sensitive to
                   changes in prevailing interest rates than higher rated investments, but are likely to be more
                   sensitive to adverse economic changes or individual corporate developments. The Fund may
                   enter into repurchase agreements, may purchase foreign securities; securities on a when-issued
                   and delayed delivery basis and may utilize certain investement techniques, all of which involve
                   certain special risks (see pages 13-17).

</TABLE>
    

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

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

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

(4)   Only applicable to redemptions made within one year after purchase (see
      "Purchase of Fund Shares--Level Load Alternative--Class C Shares").

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

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

  Class D ...............................................................      $ 9        $29         $ 51        $113
You would pay the following expenses on the same $1,000 investment
assuming no redemption at the end of the period:
  Class A ...............................................................      $64        $88         $113        $187
  Class B ...............................................................      $18        $57         $ 97        $212
  Class C ...............................................................      $19        $60         $104        $224
  Class D ...............................................................      $ 9        $29         $ 51        $113
</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 charge permitted by the NASD.

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

   
       Morgan Stanley Dean Witter Income Builder Fund (formerly named Dean
Witter Income Builder Fund) (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 The
Commonwealth of Massachusetts on March 21, 1996.

       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 assets of approximately $112.8 billion at 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 Trustees review 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 0.75% to the Fund's net assets. Effective May 1, 1998, the
Investment Manager's compensation was scaled down to 0.725% on assets over $500
million. For the fiscal year ended September 30, 1998, the Fund accrued total
compensation to the Investment Manager amounting to 0.75% of the Fund's average
daily net assets and the total expenses of each Class amounted to 1.17%, 1.80%,
1.92% and 0.92% of the average daily net assets of Class A, Class B, Class C
and Class D, respectively.

INVESTMENT OBJECTIVES AND POLICIES
- --------------------------------------------------------------------------------
    

       The primary investment objective of the Fund is to seek reasonable
income. Growth of capital is the secondary objective. The objectives are
fundamental policies of the Fund and may not be changed without a vote of a
majority of the outstanding voting securities of the Fund. There is no
assurance that the objectives will be achieved.

       The Fund seeks to achieve its objectives by investing, under normal
market conditions, at least 65% of its total assets in income-producing equity
securities, including common stock, preferred stock and convertible securities.
Up to 35% of the Fund's assets may be invested in fixed-income securities or
common stocks that do not pay a regular dividend


                                       9
<PAGE>

but are expected to contribute to the Fund's ability to meet its investment
objectives.

       Common Stocks, Preferred Stocks and Securities Convertible into Common
Stocks. The Fund will invest, under normal market conditions, primarily in
common stocks of large-cap companies which have a record of paying dividends
and, in the opinion of the Investment Manager, have the potential for
maintaining dividends, in preferred stock and in securities convertible into
common stocks of small and mid-cap companies. The Investment Manager intends to
use a value-oriented investment style in the selection of securities for the
Fund's portfolio. 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 based on a specified 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).

       Lower Rated Fixed-Income Securities. The Fund also may invest up to 20%
in fixed-income securities rated below investment grade. Securities below
investment grade are the equivalent of high yield, high risk bonds (commonly
known as "junk bonds"). Investment grade is generally considered to be debt
securities rated BBB or higher by Standard & Poor's Corporation ("S&P") or Baa
or higher by Moody's Investors Service, Inc. ("Moody's"). (Fixed-income
securities rated BBB by S&P or Baa by Moody's which generally are regarded as
having an adequate capacity to pay interest and repay principal, have
speculative characteristics.) However, the Fund will not invest in fixed-income
securities that are rated lower than B by S&P or Moody's or, if not rated,
determined to be of comparable quality by the Investment Manager. The Fund will
not invest in fixed-income securities that are in default in payment of
principal or interest. The 20% limitation on securities rated below investment
grade in which the Fund may invest does not include securities convertible into
common stock. A description of fixed-income securities ratings is contained in
the appendix to the Prospectus.

       Foreign Securities. The Fund may invest in equity securities of foreign
issuers. However, the Fund will not invest more than 25% of the value of its
total assets, at the time of purchase, in securities of foreign issuers (other
than securities of Canadian issuers registered under the Securities Exchange
Act of 1934 or American Depository Receipts, on which there is no such limit).
The Fund may invest in American Depository Receipts (ADRs), European Depository
Receipts (EDRs) or other similar securities convertible into securities of
foreign issuers. These securities may not necessarily be denominated in the
same currency as the securities into which they may be converted. ADRs are
receipts typically issued by a United States bank or trust company evidencing
ownership of the underlying securities. EDRs are European receipts evidencing a
similar arrangement. Generally, ADRs, in registered form, are designed for use
in the United States securities markets and EDRs, in bearer form, are designed
for use in European securities markets. The Fund's investments in unlisted
foreign securities are subject to the Fund's overall policy limiting its
investment in illiquid securities to 15% or less of its net assets.

       Corporate Notes and Bonds and U.S. Government Securities. A portion of
the Fund's assets may be invested in investment grade fixed income (fixed-rate
and adjustable rate) securities such as corporate notes and bonds and
obligations issued or guaranteed by the U.S. Government, its agencies and
instrumentalities.

       The non-governmental debt securities in which the Fund will invest will
include: (a) corporate debt securities, including bonds, notes and commercial
paper, rated in the four highest categories by a nationally recognized
statistical rating organization


                                       10
<PAGE>

("NRSRO") including Moody's Investors Service, Inc., Standard & Poor's
Corporation, Duff and Phelps, Inc. and Fitch Investors Service, Inc.; and (b)
bank obligations, including CDs, banker's acceptances and time deposits, issued
by banks with a long-term CD rating in one of the four highest categories by a
NRSRO. Investments in securities rated within the four highest rating
categories by a NRSRO are considered "investment grade." However, such
securities rated within the fourth highest rating category by a NRSRO have
speculative characteristics and, therefore, changes in economic conditions or
other circumstances are more likely to weaken their capacity to make principal
and interest payments than would be the case with investments in securities
with higher credit ratings. Where a fixed-income security is not rated by a
NRSRO (as may be the case with a foreign security) the Investment Manager will
make a determination of its creditworthiness and may deem it to be investment
grade. A description of fixed-income security ratings is contained in the
appendix to the Prospectus.

       The U.S. Government Securities in which the Fund may invest include
securities which are direct obligations of the United States Government, such
as United States treasury bills, notes and bonds, and which are backed by the
full faith and credit of the United States; securities which are backed by the
full faith and credit of the United States but which are obligations of a
United States agency or instrumentality (e.g., obligations of the Government
National Mortgage Association); securities issued by a United States agency or
instrumentality which has the right to borrow, to meet its obligations, from an
existing line of credit with the United States Treasury (e.g., obligations of
the Federal National Mortgage Association); securities issued by a United
States agency or instrumentality which is backed by the credit of the issuing
agency or instrumentality (e.g., obligations of the Federal Farm Credit
System).

       Money market instruments in which the Fund may invest include securities
issued or guaranteed by the U.S. Government, its agencies and instrumentalities
(Treasury bills, notes and bonds, including zero coupon securities); bank
obligations; Eurodollar certificates of deposit; obligations of savings
institutions; fully insured certificates of deposit; and commercial paper rated
within the four highest grades by Moody's or Standard & Poor's or, if not
rated, issued by a company having an outstanding debt issue rated at least AA
by Standard & Poor's or Aa by Moody's. Such securities may be used to invest
uncommitted cash balances.

       There may be periods during which, in the opinion of the Investment
Manager, market conditions warrant reduction of some or all of the Fund's
securities holdings. During such periods, the Fund may adopt a temporary
"defensive" posture in which up to 100% of its total assets is invested in
money market instruments or cash.

       In addition to the securities noted above, the Fund may invest in the
following:

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

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


                                       11
<PAGE>

basis may increase the volatility of its net asset value. See the Statement of
Additional Information for additional risk disclosure.

       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.

       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.

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

       The Securities and Exchange Commission has adopted Rule 144A under the
Securities Act, which permits the Fund to buy securities restricted as to


                                       12
<PAGE>

resale 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. However, investing
in Rule 144A securities could have the effect of increasing the level of Fund
illiquidity to the extent the Fund, at a particular point in time, may be
unable to find qualified institutional buyers interested in purchasing such
securities.

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


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's yield will
also vary based on the yield of the Fund's portfolio securities.

       Common Stocks, Preferred Stocks and Securities Convertible into Common
Stocks. The net asset value of the Fund's shares will fluctuate with changes in
market values of portfolio securities. 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).

       The Investment Manager intends to follow a "bottom-up" approach in the
selection of convertible securities. Beginning with a universe of about 500
companies, the Investment Manager will narrow the focus to small and mid-cap
companies and review the issues to determine if the convertible is trading with
the underlying equity security. The yield of the underlying equity security
will be evaluated and company fundamentals will be studied to evaluate cash
flow, risk/reward balance, valuation and the prospects for growth. The
Investment Manager intends to select convertible securities that, in its
judgment, are issued by companies with sound management practices and that
represent good value.

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

       The Fund may invest up to 25% of its total assets in "enhanced"
convertible securities. En-


                                       13

hanced convertible securities offer holders the opportunity to obtain higher
current income than would be available from a traditional equity security
issued by the same company, in return for reduced participation or a cap on
appreciation in the underlying common stock of the issuer which the holder can
realize. In addition, in many cases, enhanced convertible securities are
convertible into the underlying common stock of the issuer automatically at
maturity, unlike traditional convertible securities which are convertible only
at the option of the security holder. Enhanced convertible securities may be
more volatile than traditional convertible securities due to the mandatory
conversion feature.

       The Fund also may invest up to 10% in "synthetic" convertible
securities. Unlike traditional convertible securities whose conversion values
are based on the common stock of the issuer of the convertible security,
"synthetic" convertible securities are preferred stocks or debt obligations of
an issuer which are combined with an equity component whose conversion value is
based on the value of the common stock of a different issuer or a particular
benchmark (which may include a foreign issuer or basket of foreign stocks, or a
company whose stock is not yet publicly traded). In many cases, "synthetic"
convertible securities are not convertible prior to maturity, at which time the
value of the security is paid in cash by the issuer.

       "Synthetic" convertible securities may be less liquid than traditional
convertible securities and their price changes may be more volatile. Reduced
liquidity may have an adverse impact on the Fund's ability to sell particular
synthetic securities promptly at favorable prices and may also make it more
difficult for the Fund to obtain market quotations based on actual trades, for
purposes of valuing the Fund's portfolio securities.

       The Fund may invest without limitation in "exchangeable" convertible
bonds and convertible preferred stock which are issued by one company, but
convertible into the common stock of a different publicly traded company. These
securities generally have liquidity trading and risk characteristics similar to
traditional convertible securities noted above.

   
       Foreign securities. Foreign securities investments may be affected by
changes in currency rates or exchange control regulations, changes in
governmental administration or economic or monetary policy (in the United
States and abroad) or changed circumstances in dealings between nations.
Fluctuations in the relative rates of exchange between 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.
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 currency exchange rates are determined by forces of supply and
demand on the foreign exchange markets. These forces are themselves affected by
the international balance of payments and other economic and financial
conditions, government intervention, speculation and other factors. Moreover,
foreign currency exchange rates may be affected by the regulatory control of
the exchanges on which the currencies trade.

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


                                       14
<PAGE>

       Securities of foreign issuers may be less liquid than comparable
securities of U.S. issuers and, as such, their price changes may be more
volatile. Furthermore, foreign exchanges and broker-dealers are generally
subject to less government and exchange scrutiny and regulation than their
American counterparts. Brokerage commissions, dealer concessions and other
transaction costs may be higher on foreign markets than in the U.S. In
addition, differences in clearance and settlement procedures on foreign markets
may occasion delays in settlements of the Fund's trades effected in such
markets. As such, the inability to dispose of portfolio securities due to
settlement delays could result in losses to the Fund due to subsequent declines
in value of such securities and the inability of the Fund to make intended
security purchases due to settlement problems could result in a failure of the
Fund to make potentially advantageous investments. To the extent the Fund
purchases Eurodollar certificates of deposit issued by foreign branches of
domestic United States banks, consideration will be given to their domestic
marketability, the lower reserve requirements normally mandated for overseas
banking operations, the possible impact of interruptions in the flow of
international currency transactions and future international political and
economic developments which might adversely affect the payment of principal or
interest.

   
       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.
    

       Lower Rated Convertible and Fixed-Income Securities. A portion of the
fixed-income and convertible securities in which the Fund may invest will
generally be below investment grade. Securities below investment grade are the
equivalent of high yield, high risk bonds, commonly known as "junk bonds."
Investment grade is generally considered to be debt securities rated BBB or
higher by Standard & Poor's Corporation ("S&P") or Baa or higher by Moody's
Investors Service, Inc. ("Moody's"). Fixed-income securities rated Baa by
Moody's or BBB by Standard & Poor's have speculative characteristics greater
than those of more highly rated bonds, while fixed-income securities rated Ba
or BB or lower by Moody's and Standard & Poor's, respectively, are considered
to be speculative investments. The Fund will not invest in convertibles and
fixed-income securities that are rated lower than B by S&P or Moody's or, if
not rated, determined to be of comparable quality by the Investment Manager.
The Fund will not invest in debt securities that are in default in payment of
principal or interest. The ratings of fixed-income securities by Moody's and
Standard & Poor's are a generally accepted barometer of credit risk. However,
as the creditworthiness of issuers of lower-rated fixed-income securities is
more problematical than that of issuers of higher-rated fixed-income
securities, the achievement of the Fund's investment objective will be more
dependent upon the Investment Manager's own credit analysis than would be the
case with a mutual fund investing primarily in higher quality bonds. The
Investment Manager will utilize a security's credit rating as simply one
indication of an issuer's creditworthiness and will principally rely upon its
own analysis of any security currently held by the Fund or potentially
purchasable by the Fund for its portfolio.

   
       During the fiscal year ended September 30, 1998, the monthly dollar
weighted average ratings of the debt obligations held by the Fund, expressed as
a percentage of the Fund's total investments, were as follows:
    



   
<TABLE>
<CAPTION>
                             PERCENTAGE OF
RATINGS                    TOTAL INVESTMENTS

<S>                       <C>
  AAA/Aaa .............           0.7%
  AA/Aa ...............           0.0%
  A/A .................           2.2%
  BBB/Baa .............           7.1%
  BB/Ba ...............           6.4%
  B/B .................          13.9%
  CCC/Caa .............           0.0%
  CC/Ca ...............           0.0%
  C/C .................           0.0%
  Unrated .............           4.9%
</TABLE>
    

                                       15
<PAGE>

   
       Because of the special nature of the Fund's permitted investments in
lower rated debt securities, the Investment Manager must take account of
certain special considerations in assessing the risks associated with such
investments. Historically, the prices of lower rated securities have been found
to be less sensitive to changes in prevailing interest rates than higher rated
investments, but are likely to be more sensitive to adverse economic changes or
individual corporate developments. During an economic downturn or substantial
period of rising interest rates, highly leveraged issuers may experience
financial stress which would adversely affect their ability to service their
principal and interest payment obligations, to meet their projected business
goals or to obtain additional financing. If the issuer of a fixed-income
security owned by the Fund defaults, the Fund may incur additional expenses to
seek recovery. In addition, periods of economic uncertainty and change can be
expected to result in an increased volatility of market prices of lower rated
securities and a corresponding volatility in the net asset value of a share of
the Fund.
    

       Corporate Notes and Bonds and U.S. Government Securities. Payments of
interest and principal of U.S. Government securities are guaranteed by the U.S.
Government, however, neither the value nor the yield of corporate notes and
bonds and U.S. Government securities which may be invested in by the Fund are
guaranteed by the U.S. Government. Values and yield of corporate and government
bonds will fluctuate with changes in prevailing interest rates and other
factors. Generally, as prevailing interest rates rise, the value of corporate
notes and bonds and government bonds held by the Fund will fall. 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 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.

       Real Estate Investment Trusts. Real estate investment trusts are not
diversified and are subject to the risk of financing projects. They are also
subject to heavy cash flow dependency, defaults by borrowers or tenants,
self-liquidation, and the possibility of failing to qualify for tax-free status
under the Internal Revenue Code and failing to maintain exemption from the Act.
The Fund currently intends to invest up to 10%, but may invest up to 20% of its
assets in real estate investment trusts.

       Repurchase Agreements. While repurchase agreements involve certain risks
not associated with direct investments in debt securities, including the risks
of default or bankruptcy of the selling financial institution, the Fund follows
procedures designed to minimize such risks. These procedures include effecting
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 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.

   
       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
    


                                       16
<PAGE>

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

Objectives 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. 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 Investment Manager also may use
quantitative screens in the process of selecting portfolio securities.

       The Fund's portfolio is managed within MSDW Advisors' Growth and Income
Group, which manages 20 equity funds and fund portfolios with approximately
$32.9 billion in assets as of October 31, 1998. Paul D. Vance and Peter M.
Avelar, Senior Vice Presidents of MSDW Advisors and members of MSDW Advisors'
Growth and Income Group, have been the primary portfolio co-managers of the
Fund since its inception and January 1998, respectively, and have been
portfolio managers with MSDW Advisors for over five years.

       Although the Fund does not intend to engage in short-term trading of
portfolio securities as a means of achieving its investment objective, it may
sell portfolio securities without regard to the length of time they have been
held whenever such sale will in the Investment Manager's opinion strengthen the
Fund's position and contribute to its investment objective. The portfolio
turnover rate is not expected to exceed 90%. Brokerage commissions are not
normally charged on the purchase or sale of U.S. Government obligations, but
such transactions may involve costs in the form of spreads between bid and
asked prices. 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.
    

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

       The investment restrictions listed below are among the restrictions
which have been adopted by the Fund as fundamental policies. Under the
Investment Company Act of 1940, as amended (the "Act"), a fundamental policy
may not be changed without the vote of a majority of the outstanding voting
securities of the Fund, as defined in the Act. For purposes of the following
limitations: (i) all percentage limitations apply immediately after a purchase
or initial investment; and (ii) any subse-


                                       17
<PAGE>

quent change in any applicable percentage resulting from market fluctuations or
other changes in total or net assets does not require elimination of any
security from the portfolio.

       The Fund may not:

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


           4. Invest more than 5% of the value of its total assets in
       securities of issuers having a record, together with predecessors, of
       less than three years of continuous operation. This restriction shall
       not apply to any obligation of the United States Government, its
       agencies or instrumentalities. (See the Statement of Addi-tional
       Information for additional investment restrictions.)


       Notwithstanding any other investment policy or restriction, the Fund may
seek to achieve its investment objectives by investing all or substantially all
of its assets in another investment company having substantially the same
investment objectives 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 which 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
    


                                       18
<PAGE>

be described in the then current prospectus of the Fund. See "Alternative
Purchase Arrange-ments--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 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 Income Builder Fund, directly to
Morgan Stanley Dean Witter Trust FSB (the "Transfer Agent" or "MSDW Trust") at
P.O. Box 1040, Jersey City, NJ 07303 or by contacting a Morgan Stanley Dean
Witter Financial Advisor or other Selected Broker-Dealer representative of DWR
or other Selected Broker-Dealer. When purchasing shares of the Fund, investors
must specify whether the purchase is for Class A, Class B, Class C or Class D
shares. If no Class is specified, the Transfer Agent will not process the
transaction until the proper Class is identified. The minimum initial purchase
in the case of investments through EasyInvestSM, an automatic purchase plan
(see "Shareholder Services"), is $100, provided that the schedule of automatic
investments will result in investments totalling at least $1,000 within the
first twelve months. The minimum initial 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, administrative and/or brokerage services,
the Fund, in its discretion, may accept investments without regard to any
minimum amounts which would otherwise be required, provided, in the case of
Systematic Payroll Deduction Plans, that the Distributor has reason to believe
that additional investments will increase the investment in all accounts under
such Plans to at least $1,000. Certificates for shares purchased will not be
issued unless a request is made by the shareholder in writing to the Transfer
Agent.
    

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


ALTERNATIVE PURCHASE ARRANGEMENTS

       The Fund offers several Classes of shares to investors designed to
provide them with the flexibil-


                                       19
<PAGE>

ity 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."

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

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

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

   
       Class B Shares. Class B shares are offered at net asset value with no
initial sales charge but are subject to a CDSC (scaled down from 5.0% to 1.0%)
if redeemed within six years of purchase. (Class B shares purchased by certain
qualified 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."


                                       20
<PAGE>

       Selecting a Particular Class. In deciding which Class of Fund shares to
purchase, investors should consider the following factors, as well as any other
relevant facts and circumstances:

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

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

   
       For the purpose of meeting the $5 million (or $25 million) minimum
investment amount for Class D shares, holdings of Class A 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:

INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES

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

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

</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.
    


                                       22
<PAGE>

   
       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 $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
    


                                       23
<PAGE>

   
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.

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

CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE--
CLASS B SHARES

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

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

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

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


                                       25
<PAGE>

   
converted at that time such proportion of Class B shares acquired through
automatic reinvestment of dividends and distributions owned by the shareholder
as the total number of his or her Class B shares converting at the time bears
to the total number of outstanding Class B shares purchased and owned by the
shareholder. In the case of Class B shares held by a Qualified Retirement Plan
for which MSDW Trust serves as Trustee or DWR's Retirement Plan Services serves
as recordkeeper pursuant 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
    


                                       26
<PAGE>

   
the Distributor, pursuant to which such persons pay an asset based fee for
services in the nature of investment advisory or administrative services
(subject to all of the terms and conditions of such programs, referred to in
(i) and (ii) above, which may include termination fees, mandatory redemption
upon termination and such other circumstances as specified in the programs'
agreements, and restrictions on transferability of Fund shares); (iii) 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
sharehold-
    


                                       27
<PAGE>

ers; and preparation, printing and distribution of sales literature and
advertising materials. In addition, the Distributor may utilize fees paid
pursuant to the Plan in the case of Class B shares to compensate DWR and other
Selected Broker-Dealers for their opportunity costs in advancing such amounts,
which compensation would be in the form of a carrying charge on any
unreimbursed expenses.

   
       For the fiscal year ended September 30, 1998, Class B shares of the Fund
accrued payments under the Plan amounting to $3,886,869, which amount is equal
to 0.88% of the average daily net assets of Class B for the fiscal year. These
payments were calculated pursuant to clause (a) of the compensation formula
under the Plan. For the fiscal year ended September 30, 1998, Class A and Class
C shares of the Fund accrued payments under the Plan amounting to $18,844 and
$41,480, respectively, which amounts are equal to 0.25% and 1.00% 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 in
distributing Class B shares of the Fund may be in excess of the total of (i)
the payments made by the Fund pursuant to the Plan, and (ii) the proceeds of
CDSCs paid by investors upon the redemption of Class B shares. For example, if
$1 million in expenses in distributing Class B shares of the Fund had been
incurred and $750,000 had been received as described in (i) and (ii) above, the
excess expense would amount to $250,000. The Distributor has advised the Fund
that such excess amounts, including the carrying charge described above,
totalled $18,378,964 at September 30, 1998, which was equal to 4.41% of the net
assets of Class B on such date. Because there is no requirement under the Plan
that the Distributor be reimbursed for all distribution expenses or any
requirement that the Plan be continued from year to year, such excess amount
does not constitute a liability of the Fund. Although there is no legal
obligation for the Fund to pay expenses incurred in excess of payments made to
the Distributor under the Plan, and the proceeds of CDSCs paid by investors
upon redemption of shares, if for any reason the Plan is terminated the
Trustees will consider at that time the manner in which to treat such expenses.
Any cumulative expenses incurred, but not yet recovered through distribution
fees or CDSCs, may or may not be recovered through future distribution fees or
CDSCs.

       In the case of Class A and Class C shares, expenses incurred pursuant to
the Plan in any calendar year in excess of 0.25% or 1.0% of the average daily
net assets of Class A or Class C, respectively, will not be reimbursed by the
Fund through payments in any subsequent year, except that expenses representing
a gross sales commission credited to Morgan Stanley Dean Witter Financial
Advisor or other Selected Broker-Dealer representative 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 $16,788 in the case
of Class C at December 31, 1997, which was equal to 0.72% of the net assets of
Class C on such date, and that there were no such expenses which 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, on each day that the New York Stock Exchange is open (or, on days
when the New York Stock Exchange closes prior to 4:00 p.m., at such earlier
time), 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


                                       28
<PAGE>

liabilities. The net asset value per share will not be determined on Good
Friday and on such other federal and non-federal holidays as are observed by
the New York Stock Exchange.

       In the calculation of the Fund's net asset value: (1) an equity
portfolio security listed or traded on the New York or American Stock Exchange
or other domestic or foreign stock exchange is valued at its latest sale price
on that exchange prior to the time assets are valued; if there were no sales
that day, the security is valued at the latest bid price (in cases where a
security is traded on more than one exchange, the security is valued on the
exchange designated as the primary market pursuant to procedures adopted by the
Trustees); (2) all other portfolio securities for which over-the-counter market
quotations are readily available are valued at the latest bid price; (3) when
market quotations are not readily available, including circumstances under
which it is determined by the Investment Manager that sale or bid prices are
not reflective of a security's market value, portfolio securities are valued at
their fair value as determined in good faith under procedures established by
and under the general supervision of the Fund's 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); (4) the value
of short-term debt securities which mature at a date less than sixty days
subsequent to valuation date will be determined on an amortized cost or
amortized value basis; and (5) the value of other assets will be determined in
good faith at fair value under procedures established by and under the general
supervision of the Fund's Trustees. Dividends receivable are accrued as of the
ex-dividend date. Interest income is accrued daily. Certain securities in the
Fund's portfolio may be valued by an outside pricing service approved by the
Fund's Trustees.

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").
    

       Investment of Dividends or Distributions Received in Cash. Any
shareholder who receives a cash payment representing a dividend or capital
gains distribution may invest such dividend or distribution in shares of the
applicable Class at the net asset value 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").

   
       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").

       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
    


                                       29
<PAGE>

   
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 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-annually 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.

       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.

       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.
    


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 purchase (not by exchange
or dividend reinvestment) have been held for thirty days. There
    


                                       30
<PAGE>

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 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 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 exchange of
shares of the Fund pledged in the margin account.
    


                                       31
<PAGE>

       The current prospectus for each fund describes its investment
objective(s) and policies, and shareholders should obtain a copy and read 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 has realized 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 who are clients of DWR or other 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 Fund, 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.

       Additional information on the above is available from a Morgan Stanley
Dean Witter Financial Advisor or other Selected Broker-Dealer representative or
from the Transfer Agent.
    

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 documentation required by the Transfer Agent.


                                       32
<PAGE>

       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 or telegraphic request of the shareholder. The repurchase
price is the net asset value per share next determined (see "Purchase of Fund
Shares") after such purchase order is received by DWR or another Selected
Broker-Dealer.

       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 the 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 to redeem, upon
sixty days' notice and at 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 have a value of
less than $100 as a result of redemptions or repurchases, 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 to make an additional investment in an amount which will increase
the value of the account to at least the applicable amount before the
redemption is processed. No CDSC will be imposed on any involuntary redemption.
 

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

       Dividends and Distributions. The Fund declares dividends separately for
each Class of shares and intends to pay quarterly income dividends and to
distribute substantially all of the Fund's net short-term and net long-term
capital gains, if there are any, at least once each year. The Fund may,
however, determine either to distribute or to retain all or part of any net
long-term capital gains in any year for reinvestment.

       All dividends and any capital gains distributions will be paid in
additional shares of the same Class and automatically credited to the
shareholder's account without issuance of a share certificate unless


                                       33
<PAGE>

the shareholder requests in writing that all dividends 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 short-term capital gains to shareholders and otherwise 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 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 dividend income regardless of whether the shareholder receives such
distributions in additional shares or in cash. Any dividends declared in the
last quarter of any calendar year which are paid in the following year prior to
February 1 will be deemed, for tax purposes, to have been received by the
shareholder in the prior year.
    

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


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


   
       After the end of the calendar year, shareholders will be sent full
information on their dividends and capital gains distributions for tax
purposes. Shareholders will also be notified of their proportionate share of
long-term capital gains distributions that are eligible for a reduced rate of
tax under the Taxpayer Relief Act of 1997. To avoid being subject to a 31%
federal backup withholding tax on taxable dividends, capital gains
distributions and the proceeds of redemptions and repurchases, shareholders'
taxpayer identification numbers must be furnished and certified as to their
accuracy.


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

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

       From time to time the Fund may quote its "yield" and/or its "total
return" in advertisements and sales literature. These figures are computed
separately for Class A, Class B, Class C and Class D shares. Both the yield and
the total return of the Fund are based on historical earnings and are not
intended to indicate future performance. The yield of each Class of the Fund is
computed by dividing the Class's net investment income over a 30-day period by
an average value (using the average number of shares entitled to receive
dividends and the net asset value per share at the end of the period), all in
accordance with applicable regulatory requirements. Such amount is compounded
for six months and then annualized for a twelve-month period to derive the
yield for each Class.

       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 "aver-


                                       34
<PAGE>

age 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, or over the life of the Fund, if less than any of the foregoing. Total
return and average annual total return reflect 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. 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. Such calculations may or may not
reflect the deduction of any sales charge which, if reflected, would reduce the
performance quoted. 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., the S&P 500 Index and the Lehman Brothers
Government/  Corporate Bond Index).

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 limited 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 notice of such Fund obligations include such disclaimer, and
provides for indemnification out of the Fund's property for any shareholder
held personally liable for the obligations of the Fund. Thus, the risk of a
shareholder incurring financial loss on account of shareholder liability is
limited to circumstances in which the Fund itself would be unable to meet its
obligations. Given the above limitations on shareholder personal liability, and
the nature of the Fund's assets and operations, 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 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 ad-

vance 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
prohibits engaging in futures and options transactions and profiting on
short-term trading (that is, a purchase within 60 days of a sale or a sale
within 60 days of a purchase) of a security. In addition, investment personnel
may not purchase or sell a security for their personal account within 30 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 objectives by investing all of its investable assets in a
diversified, open-end management investment company having the same investment
objectives 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

RATINGS OF CORPORATE DEBT INSTRUMENTS INVESTMENTS

MOODY'S INVESTORS SERVICE INC. ("MOODY'S")

                         FIXED-INCOME SECURITY RATINGS

<TABLE>
<S>     <C>
Aaa     Fixed-income securities which are rated Aaa are judged to be of the best quality. They carry the
        smallest degree of investment risk and are generally referred to as "gilt edge." Interest payments
        are protected by a large or by an exceptionally stable margin and principal is secure. While the
        various protective elements are likely to change, such changes as can be visualized are most
        unlikely to impair the fundamentally strong position of such issues.

Aa      Fixed-income securities which are rated Aa are judged to be of high quality by all standards.
        Together with the Aaa group they comprise what are generally known as high grade fixed-
        income securities. They are rated lower than the best fixed-income securities because margins
        of protection may not be as large as in Aaa securities or fluctuation of protective elements may
        be of greater amplitude or there may be other elements present which make the long-term risks
        appear somewhat larger than in Aaa securities.

A       Fixed-income securities which are rated A possess many favorable investment attributes and are
        to be considered as upper medium grade obligations. Factors giving security to principal and
        interest are considered adequate, but elements may be present which suggest a susceptibility
        to impairment sometime in the future.

Baa     Fixed-income securities which are rated Baa are considered as medium grade obligations; i.e.,
        they are neither highly protected nor poorly secured. Interest payments and principal security
        appear adequate for the present but certain protective elements may be lacking or may be
        characteristically unreliable over any great length of time. Such fixed-income securities lack
        outstanding investment characteristics and in fact have speculative characteristics as well.

        Fixed-income securities rated Aaa, Aa, A and Baa are considered investment grade.

Ba      Fixed-income securities which are rated Ba are judged to have speculative elements; their future
        cannot be considered as well assured. Often the protection of interest and principal payments
        may be very moderate, and therefore not well safeguarded during both good and bad times in
        the future. Uncertainty of position characterizes bonds in this class.

B       Fixed-income securities which are rated B generally lack characteristics of a desirable
        investment. Assurance of interest and principal payments or of maintenance of other terms of the
        contract over any long period of time may be small.

Caa     Fixed-income securities which are rated Caa are of poor standing. Such issues may be in default
        or there may be present elements of danger with respect to principal or interest.

Ca      Fixed-income securities which are rated Ca present obligations which are speculative in a high
        degree. Such issues are often in default or have other marked shortcomings.

C       Fixed-income securities which are rated C are the lowest rated class of fixed-income securities,
        and issues so rated can be regarded as having extremely poor prospects of ever attaining any
        real investment standing.
</TABLE>


                                       37
<PAGE>

     Rating Refinements: Moody's may apply numerical modifiers, 1, 2, and 3 in
each generic rating classification from Aa through B in its municipal
fixed-income security rating system. The modifier 1 indicates that the security
ranks in the higher end of its generic rating category; the modifier 2
indicates a mid-range ranking; and a modifier 3 indicates that the issue ranks
in the lower end of its generic rating category.


                           COMMERCIAL PAPER RATINGS


     Moody's Commercial Paper ratings are opinions of the ability to repay
punctually promissory obligations not having an original maturity in excess of
nine months. The ratings apply to Municipal Commercial Paper as well as taxable
Commercial Paper. Moody's employs the following three designations, all judged
to be investment grade, to indicate the relative repayment capacity of rated
issuers: Prime-1, Prime-2, Prime-3.


     Issuers rated Prime-1 have a superior capacity for repayment of short-term
promissory obligations. Issuers rated Prime-2 have a strong capacity for
repayment of short-term promissory obligations; and issuers rated Prime-3 have
an acceptable capacity for repayment of short-term promissory obligations.
Issuers rated Not Prime do not fall within any of the Prime rating categories.


STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S")


                         FIXED-INCOME SECURITY RATINGS


     A Standard & Poor's fixed-income security rating is a current assessment
of the creditworthiness of an obligor with respect to a specific obligation.
This assessment may take into consideration obligors such as guarantors,
insurers, or lessees.


     The ratings are based on current information furnished by the issuer or
obtained by Standard & Poor's from other sources it considers reliable. The
ratings are based, in varying degrees, on the following considerations: (1)
likelihood of default-capacity and willingness of the obligor as to the timely
payment of interest and repayment of principal in accordance with the terms of
the obligation; (2) nature of and provisions of the obligation; and (3)
protection afforded by, and relative position of, the obligation in the event
of bankruptcy, reorganization or other arrangement under the laws of bankruptcy
and other laws affecting creditors' rights.


     Standard & Poor's does not perform an audit in connection with any rating
and may, on occasion, rely on unaudited financial information. The ratings may
be changed, suspended or withdrawn as a result of changes in, or unavailability
of, such information, or for other reasons.



<TABLE>
<S>     <C>
AAA     Fixed-income securities rated "AAA" have the highest rating assigned by Standard & Poor's.
        Capacity to pay interest and repay principal is extremely strong.

AA      Fixed-income securities rated "AA" have a very strong capacity to pay interest and repay
        principal and differs from the highest-rate issues only in small degree.

A       Fixed-income securities rated "A" have a strong capacity to pay interest and repay principal
        although they are somewhat more susceptible to the adverse effects of changes in
        circumstances and economic conditions than fixed-income securities in higher-rated categories.
</TABLE>


                                       38
<PAGE>

<TABLE>
<S>     <C>
BBB     Fixed-income securities rated "BBB" are regarded as having an adequate capacity to pay
        interest and repay principal. Whereas it normally exhibits adequate protection parameters,
        adverse economic conditions or changing circumstances are more likely to lead to a weakened
        capacity to pay interest and repay principal for fixed-income securities in this category than for
        fixed-income securities in higher-rated categories.

        Fixed-income securities rated AAA, AA, A and BBB are considered investment grade.

BB      Fixed-income securities rated "BB" have less near-term vulnerability to default than other
        speculative grade fixed-income securities. However, it faces major ongoing uncertainties or
        exposures to adverse business, financial or economic conditions which could lead to
        inadequate capacity or willingness to pay interest and repay principal.

B       Fixed-income securities rated "B" have a greater vulnerability to default but presently have the
        capacity to meet interest payments and principal repayments. Adverse business, financial or
        economic conditions would likely impair capacity or willingness to pay interest and repay
        principal.

CCC     Fixed-income securities rated "CCC" have a current identifiable vulnerability to default, and are
        dependent upon favorable business, financial and economic conditions to meet timely
        payments of interest and repayments of principal. In the event of adverse business, financial
        or economic conditions, they are not likely to have the capacity to pay interest and repay
        principal.

CC      The rating "CC" is typically applied to fixed-income securities subordinated to senior debt which
        is assigned an actual or implied "CCC" rating.

C       The rating "C" is typically applied to fixed-income securities subordinated to senior debt which
        is assigned an actual or implied "CCC-" rating.

Cl      The rating "Cl" is reserved for fixed-income securities on which no interest is being paid.

NR      Indicates that no rating has been requested, that there is insufficient information on which to
        base a rating or that Standard & Poor's does not rate a particular type of obligation as a matter
        of policy.

        Fixed-income securities rated "BB," "B," "CCC," "CC" and "C" are regarded as having
        predominantly speculative characteristics with respect to capacity to pay interest and repay
        principal. "BB" indicates the least degree of speculation and "C" the highest degree of
        speculation. While such fixed-income securities will likely have some quality and protective
        characteristics, these are outweighed by large uncertainties or major risk exposures to adverse
        conditions.

        Plus (+) or minus (-): The rating from "AA" to "CCC" may be modified by the addition of a plus
        or minus sign to show relative standing within the major ratings categories.
</TABLE>

                           COMMERCIAL PAPER RATINGS

     Standard & Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more
than 365 days. The commercial paper rating is not a recommendation to purchase
or sell a security. The ratings are based upon current information furnished by
the issuer or obtained by Standard & Poor's from other sources it considers
reliable. The ratings may be changed, suspended, or withdrawn as a result of
changes in or unavailability of such information. Ratings are


                                       39
<PAGE>

graded into group categories, ranging from "A" for the highest quality
obligations to "D" for the lowest. Ratings are applicable to both taxable and
tax-exempt commercial paper. The categories are as follows:


     Issues assigned A ratings are regarded as having the greatest capacity for
timely payment. Issues in this category are further refined with the
designation 1, 2, and 3 to indicate the relative degree of safety.



<TABLE>
<S>     <C>
A-1     indicates that the degree of safety regarding timely payment is very strong.

A-2     indicates capacity for timely payment on issues with this designation is strong. However, the
        relative degree of safety is not as overwhelming as for issues designated "A-1."

A-3     indicates a satisfactory capacity for timely payment. Obligations carrying this designation are,
        however, somewhat more vulnerable to the adverse effects of changes in circumstances than
        obligations carrying the higher designations.
</TABLE>

                                 BOND RATINGS

FITCH INVESTORS SERVICE, INC. ("FITCH")


     The Fitch Bond Ratings provides a guide to investors in determining the
investment risk associated with a particular security. The rating represents
its assessment of the issuer's ability to meet the obligations of a specific
debt issue or class of debt in a timely manner. Fitch bond ratings are not
recommendations to buy, sell or hold securities since they incorporate no
information on market price or yield relative to other debt instruments.


     The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the record of the issuer and
of any guarantor, as well as the political and economic environment that might
affect the future financial strength and credit quality of the issuer.


     Bonds which have the same rating are of similar but not necessarily
identical investment quality since the limited number of rating categories
cannot fully reflect small differences in the degree of risk. Moreover, the
character of the risk factor varies from industry to industry and between
corporate, health care and municipal.


     In assessing credit risk, Fitch Investors Service relies on current
information furnished by the issuer and/or guarantor and other sources which it
considers reliable. Fitch does not perform an audit of the financial statements
used in assigning a rating.


     Ratings may be changed, withdrawn or suspended at any time to reflect
changes in the financial condition of the issuer, the status of the issue
relative to other debt of the issuer, or any other circumstances that Fitch
considers to have a material effect on the credit of the obligor.



<TABLE>
<S>     <C>
AAA     rated bonds are considered to be investment grade and of the highest credit quality. The obligor
        has an exceptionally strong ability to pay interest and repay principal, which is unlikely to be
        affected by reasonably foreseeable events.

AA      rated bonds are considered to be investment grade and of very high credit quality. The obligor's
        ability to pay interest and repay principal, while very strong, is somewhat less than for AAA
        rated securities or more subject to possible change over the term of the issue.

<PAGE>


<TABLE>
<S>     <C>
A       rated bonds are considered to be investment grade and of high credit quality. The obligor's
        ability to pay interest and repay principal is considered to be strong, but may be more
        vulnerable to adverse changes in economic conditions and circumstances than bonds with
        higher ratings.

BBB     rated bonds are considered to be investment grade and of satisfactory credit quality. The
        obligor's ability to pay interest and repay principal is considered to be adequate. Adverse
        changes in economic conditions and circumstances, however, are more likely to weaken this
        ability than bonds with higher ratings.

BB      rated bonds are considered speculative and of low investment grade. The obligor's ability to
        pay interest and repay principal is not strong and is considered likely to be affected over time
        by adverse economic changes.

B       rated bonds are considered highly speculative. Bonds in this class are lightly protected as to
        the obligor's ability to pay interest over the life of the issue and repay principal when due.

CCC     rated bonds may have certain identifiable characteristics which, if not remedied, could lead to
        the possibility of default in either principal or interest payments.

CC      rated bonds are minimally protected. Default in payment of interest and/or principal seems
        probable.

C       rated bonds are in imminent default in payment of interest and/or principal.
</TABLE>

                              SHORT-TERM RATINGS

   
     Fitch's short-term ratings apply to debt obligations that are payable on
demand or have original maturities of generally up to three years, including
commercial paper, certificates of deposit, medium-term notes, and municipal and
investment notes. Although the credit analysis is similar to Fitch's bond
rating analysis, the short-term rating places greater emphasis on the existence
of liquidity necessary to meet the issuer's obligations in a timely manner.
Fitch's short-term ratings are as follows:
    



   
<TABLE>
<S>          <C>
Fitch-1+     (Exceptionally Strong Credit Quality) Issues assigned this rating are regarded as having the
             strongest degree of assurance for timely payment.

Fitch-1      (Very Strong Credit Quality) Issues assigned this rating reflect an assurance of timely
             payment only slightly less in degree than issues rated Fitch-1+.

Fitch-2      (Good Credit Quality) Issues assigned this rating have a satisfactory degree of assurance for
             timely payment but the margin of safety is not as great as the two higher categories.

Fitch-3      (Fair Credit Quality) Issues assigned this rating have characteristics suggesting that the
             degree of assurance for timely payment is adequate, however, near-term adverse change is
             likely to cause these securities to be rated below investment grade.

Fitch-S      (Weak Credit Quality) Issues assigned this rating have characteristics suggesting a minimal
             degree of assurance for timely payment and are vulnerable to near term adverse changes in
             financial and economic conditions.

D            (Default) Issues assigned this rating are in actual or imminent payment default.

LOC          This symbol LOC indicates that the rating is based on a letter of credit issued by a commercial
             bank.

                               LONG-TERM RATINGS

DUFF & PHELPS, INC.


     These ratings represent a summary opinion of the issuer's long-term
fundamental quality. Rating determination is based on qualitative and
quantitative factors which may vary according to the basic economic and
financial characteristics of each industry and each issuer. Important
considerations are vulnerability to economic cycles as well as risks related to
such factors as competition, government action, regulation, technological
obsolescence, demand shifts, cost structure, and management depth and
expertise. The projected viability of the obligor at the trough of the cycle is
a critical determination.


     Each rating also takes into account the legal form of the security, (e.g.,
first mortgage bonds, subordinated debt, preferred stock, etc.). The extent of
rating dispersion among the various classes of securities is determined by
several factors including relative weightings of the different security classes
in the capital structure, the overall credit strength of the issuer, and the
nature of covenant protection. Review of indenture restrictions is important to
the analysis of a company's operating and financial constraints.


     The Credit Rating Committee formally reviews all ratings once per quarter
(more frequently, if necessary).



<TABLE>
<CAPTION>
RATING SCALE     DEFINITION
<S>              <C>
AAA              Highest credit quality. The risk factors are negligible, being only slightly more than risk-free
                 U.S. Treasury debt.

AA+              High credit quality. Protection factors are strong. Risk is modest, but may vary slightly from

AA               time to time because of economic conditions.

AA-

A+               Protection factors are average but adequate. However, risk factors are more variable and

A                greater in periods of economic stress.

A-

BBB+             Below average protection factors but still considered sufficient for prudent investment.

BBB              Considerable variability in risk during economic cycles.

BBB-

BB+              Below investment grade but deemed likely to meet obligations when due. Present or

BB               prospective financial protection factors fluctuate according to industry conditions or

BB-              company fortunes. Overall quality may move up or down frequently within this category.

B+               Below investment grade and possessing risk that obligations will not be met when due.

B                Financial protection factors will fluctuate widely according to economic cycles, industry

B-               conditions and/or company fortunes. Potential exists for frequent changes in the quality
                 rating within this category or into a higher or lower quality rating grade.

CCC              Well below investment grade securities. May be in default or considerable uncertainty
                 exists as to timely payment of principal, interest or preferred dividends. Protection factors
                 are narrow and risk can be substantial with unfavorable economic/ industry conditions,
                 and/or with unfavorable company developments.

DD               Defaulted debt obligations. Issuer failed to meet scheduled principal and/or interest
                 payments.

DP               Preferred stock with dividend arrearages.

                              SHORT-TERM RATINGS


     Duff & Phelps' short-term ratings are consistent with the rating criteria
utilized by money market participants. The ratings apply to all obligations
with maturities of under one year, including commercial paper, the uninsured
portion of certificates of deposit, unsecured bank loans, master notes, bankers
acceptances, irrevocable letters of credit, and current maturities of long-term
debt. Asset-backed commercial paper is also rated according to this scale.


     Emphasis is placed on liquidity which is defined as not only cash from
operations, but also access to alternative sources of funds, including trade
credit, bank lines, and the capital markets. An important consideration is the
level of an obligor's reliance on short-term funds on an ongoing basis.


<TABLE>
<C>              <C>
A. CATEGORY 1:   HIGH GRADE

Duff 1+          Highest certainty of timely payment. Short-term liquidity, including internal
                 operating factors and/or access to alternative sources of funds, is outstanding,
                 and safety is just below risk-free U.S. Treasury short-term obligations.

Duff 1           Very high certainty of timely payment. Liquidity factors are excellent and
                 supported by good fundamental protection factors. Risk factors are minor.

Duff-            High certainty of timely payment. Liquidity factors are strong and supported by
                 good fundamental protection factors. Risk factors are very small.

B. CATEGORY 2:   GOOD GRADE

Duff 2           Good certainty of timely payment. Liquidity factors and company fundamentals
                 are sound. Although ongoing funding needs may enlarge total financing
                 requirements, access to capital markets is good. Risk factors are small.

C. CATEGORY 3:   SATISFACTORY GRADE

Duff 3           Satisfactory liquidity and other protection factors qualify issue as to investment
                 grade. Risk factors are larger and subject to more variation. Nevertheless,
                 timely payment is expected.

D. CATEGORY 4:   NON-INVESTMENT GRADE

Duff 4           Speculative investment characteristics. Liquidity is not sufficient to insure
                 against disruption in debt service. Operating factors and market access may be
                 subject to a high degree of variation.

E. CATEGORY 5:   DEFAULT

Duff 5           Issuer failed to meet scheduled principal and/or interest payments.

     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.


   
     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 and bookkeeping and certain legal services as the Fund
may reasonably require in the conduct of its business, including the
preparation of prospectuses, statements of additional information, 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.
    


                                       5
<PAGE>

   
     Expenses not expressly assumed by the Investment Manager under the
Agreement or by Morgan Stanley Dean Witter Distributiors Inc., the Distributor
of the Fund's shares ("MSDW Distributors" or "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, stock transfer and dividend disbursing agent; brokerage
commissions; taxes; engraving and printing of share certificates; registration
costs of the Fund and its shares under federal and state securities laws; 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 of 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 annual
rate of 0.75% to the Fund's daily net assets. Effective May 1, 1998, the
Investment Manager's compensation was scaled down to 0.725% on assets over $500
million. For the fiscal period June 26, 1996 (commencement of operations)
through September 30, 1996, and for the fiscal years ended September 30, 1997
and 1998, the Fund accrued total compensation to the Investment Manager in the
amount of $242,252, $1,868,871 and $3,387,158, 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 Investment Manager paid the organizational expenses of the Fund, in
the amount of $163,660, incurred prior to the offering of the Fund's shares.
The Fund has reimbursed the Investment Manager for such expenses. The
organizational expenses of the Fund have been deferred by the Fund and are
being amortized on the straight line method over a period not to exceed five
years from the date of commencement of the Fund's operations.

   
     The Agreement was initially approved by the 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
April 17, 1996 and by MSDW Advisors, as the then sole shareholder, on April 17,
1996. 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 of the outstanding shares of the Fund, as defined in the Act, or by
the 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. At their
meeting held on April 30, 1998, the Trustees of the Fund amended the Agreement
to lower the management fees charged on the Fund's average daily net assets in
excess of $500 million.

     The following owned 5% or more of the outstanding shares of Class A on
October 31, 1998: Morgan Stanley Dean Witter Trust FSB, custodian for FBO
Chattanooga Housing Authority Retirement Plan, PO Box 957, Jersey City, NJ
07303-0957--5.7%. The following owned 25% or more of the outstanding shares of
Class D on October 31, 1998: Morgan Stanley Dean Witter Trust FSB, agent for
American Baptist Homes Foundation of the West Inc., TTEE FBO Gift Annuity,
Jersey City, New Jersey 07311--61%.

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

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
    


                                       10
<PAGE>

   
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 and officers of the Fund who are or have been
employed by the Investment Manager or an affiliated company receive no
compensation or expense reimbursement from the Fund 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.

Independent Trustees by the Fund for the fiscal year ended September 30, 1998.

Independent Trustees for the calendar year ended December 31, 1997 for services
to the 84 Morgan Stanley Dean Witter Funds and, in the case of Messrs. Haire,

December 31, 1997. Mr. Haire serves as Chairman of the Audit Committee of each
Morgan Stanley Dean Witter Fund and each TCW/DW Fund and, prior to June 1,
1998, also served as Chairman of the Independent Directors or Trustees of those
Funds. With respect to Messrs. Haire, Johnson, Nugent and Schroeder, the TCW/DW
Funds are included solely because of a limited exchange privilege between those
Funds and five Morgan Stanley Dean Witter Money Market Funds. Mr. Hedien's term
as Director or Trustee of each Morgan Stanley Dean Witter Fund commenced on
September 1, 1997.

     As of the date of this Statement of Additional Information, 57 of the
Morgan Stanley Dean Witter Funds, not 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.


- --------------------
(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
- --------------------------------------------------------------------------------

   
     As discussed in the Prospectus, the Fund offers investors an opportunity
to participate in a diversified portfolio of securities, consisting, under
normal market conditions of at least 65% of its total assets in
income-producing equity securities, in preferred stocks and securities
convertible into common stock. Up to 35% of the Fund's assets may be invested
in fixed-income securities or common stocks that do not pay a regular dividend
but are expected to contribute to the Fund's ability to meet its investment
objectives. The Fund has no intention of investing in excess of 50% of its net
assets in lower rated convertibles and fixed-income securities for the fiscal
year ending September 30, 1999.
    

REPURCHASE AGREEMENTS

     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 the collateral are not subject to any limits.


                                       13
<PAGE>

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS

     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 commitment. While the Fund will only purchase securities
on a when-issued, delayed delivery or forward commitment basis with the
intention of acquiring the securities, the Fund may sell the securities before
the settlement date, if it is deemed advisable. The securities so purchased or
sold are subject to market fluctuation and no interest or dividends accrue to
the purchaser prior to the settlement date. At the time the Fund makes the
commitment to purchase or sell securities on a when-issued, delayed delivery or
forward commitment basis, it will record the transaction and thereafter reflect
the value, each day, of such security purchased, or if a sale, the proceeds to
be received, in determining its net asset value. At the time of delivery of the
securities, their value may be more or less than the purchase or sale price.
The Fund will also establish a segregated account with its custodian bank in
which it will continually maintain cash or cash equivalents or other liquid
portfolio securities equal in value to commitments to purchase securities on a
when-issued, delayed delivery or forward commitment basis.


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 or debt
restructuring. The commitment for the purchase of any such security will not be
recognized in the portfolio of the Fund until the Investment Manager determines
that issuance of the security is probable. At such time, the Fund will record
the transaction and, in determining its net asset value, will reflect the value
of the security daily. At such time, the Fund will also establish a segregated
account with its custodian bank in which it will maintain cash or cash
equivalents or other liquid portfolio securities equal in value to recognized
commitments for such securities. 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"). 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 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 sale.
    


RULE 144A 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. The procedures require that the following factors be taken into account
in making a liquidity determination: (1) the frequency of trades and price
quotes for the security; (2) the number of dealers and other potential
purchasers who have issued quotes on the security; (3) any dealer undertakings
to make a market in the security; and (4) the nature of the security and the
nature of the marketplace trades (the time needed to dispose of the security,
the method of soliciting offers, and the mechanics of transfer). 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.

     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 notice provisions described below), 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 equal to at least 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


                                       14
<PAGE>

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
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 loan 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 market price during
the loan 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.

     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 will pay reasonable finder's,
administrative and custodial fees in connection with a loan of its securities.

     New Instruments. New financial products and various combinations thereof
continue to be developed. The Fund may invest in any such products as may be
developed, to the extent conistent with its investment objective and applicable
regulatory requirements.


PORTFOLIO TURNOVER

   
     The Fund's portfolio turnover rate for the fiscal years ended September
30, 1997 and 1998 was approximately 74% and 58%, respectively. A 100% turnover
rate would occur, for example, if 100% 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, if the holders of 50% of the outstanding shares of the
Fund are present or represented by proxy or (b) more than 50% of the
outstanding shares of the Fund. For purposes of the following restrictions: (i)
all percentage limitations apply immediately after a purchase or initial
investment; and (ii) any subsequent change in any applicable percentage
resulting from market fluctuations or other changes in total or net assets does
not require elimination of any security from the portfolio.

     The Fund may not:

     1. Invest in securities of any issuer if in the exercise of reasonable
   diligence, the Fund has determined that any officer or trustee/director of
   the Fund or of the Investment Manager owns more than 1/2 of 1% of the
   outstanding securities of such issuer, and such officers and
   trustees/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 (including limited
   partnership interests), although the Fund may purchase securities of
   issuers which engage in real estate operations and securities secured by
   real estate or interests therein.

     3. Purchase or sell commodities.

                                       15
<PAGE>

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

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

     6. Borrow money, except that the Fund may borrow from a bank for
   temporary or emergency purposes in amounts not exceeding 5% (taken at the
   lower of cost or current value) of its total assets (not including the
   amount borrowed).

     7.  Pledge its assets or assign or otherwise encumber them except to
   secure borrowings effected within the limitations set forth in restriction
   (6).

     8. 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; (c) purchasing any securities on a
   when-issued or delayed delivery basis; or (d) lending portfolio securities.
    

     9. 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.

     10. Make short sales of securities.

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

     12. 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.

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

     In addition, the Fund, as non-fundamental policies, will not invest in
options or futures contracts or in more than 5% of the value of its net assets
in warrants, including not more than 2% of such assets in warrants not listed
on the New York or American Stock Exchange. However, the acquisition of
warrants attached to other securities is not subject to this restriction.

     Notwithstanding any other investment policy or restriction, the Fund may
seek to achieve its investment objectives by investing all or substantially all
of its assets in another investment company having substantially the same
investment objectives 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. Options and futures transactions will usually be
effected through a broker and a commission will be charged. 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
period June 26, 1996 (commencement of operations) through September 30, 1996
and the fiscal years ended September 30, 1997 and 1998, the Fund paid $100,337,
$224,501 and $314,715, respectively, in brokerage commissions.
    

     Many of the Fund's portfolio transactions will occur primarily with
issuers, underwriters or major dealers in U.S. Government Securities acting as
principals. Such transactions are normally on a net


                                       16
<PAGE>

basis which do not involve payment of brokerage commissions. The cost of
securities purchased from an underwriter usually includes a commission paid by
the issuer to the underwriters; transactions with dealers normally reflect the
spread between bid and asked prices.

   
     The Investment Manager currently serves as investment manager to a number
of clients, including other investment companies, and may in the future act as
investment manager or adviser to others. It is the practice of the Investment
Manager to cause purchase and sale transactions to be allocated among the Fund
and others whose assets it manages in such manner as it deems equitable. In
making such allocations among the Fund and other client accounts, various
factors may be 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 executions 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 possible 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 prices and
executions 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 investments;
wire services; and appraisals or evaluations of portfolio securities. During
the fiscal year ended September 30, 1998, the Fund paid $160,575 in brokerage
commissions in connection with transactions in the aggregate amount of
$88,677,861, 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 thereby 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
    


                                       17
<PAGE>

   
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 Board of 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 period June 26,
1996 (commencement of operations) through September 30, 1996 and the fiscal
years ended September 30, 1997 and 1998, the Fund paid a total of $24,548,
$82,810 and $141,296, respectively, in brokerage commissions to DWR. The
brokerage commissions paid to DWR represented approximately 44.90% of the total
brokerage commissions paid by the Fund for the fiscal year ended September 30,
1998 and were paid on account of transactions having an aggregate dollar value
equal to approximately 53.7% of the aggregate dollar value of all portfolio
transactions of the Fund during the fiscal year for which commissions were
paid. During the period June 1, 1997 through September 30, 1997 the Fund did
not pay any brokerage commissions to MS & Co. and during the fiscal year ended
September 30, 1998, the Fund paid a total of $6,600 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 2.10% 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 2.73% 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 period June 26, 1996 (commencement of
operations) through September 30, 1996 and the fiscal years ended September 30,
1997 and 1998, the Fund did not effect any principal transactions with DWR.

     During the fiscal year ended September 30, 1998, the Fund purchased
preferred stock of Merrill Lynch & Co., which issuer was among the ten brokers
or the ten dealers which executed transactions for or with the Fund in the
largest dollar amounts during the period. At September 30, 1998, the Fund held
preferred stock of two companies, each issued by Merrill Lynch & Co. with a
market value of $1,991,250 and $1,886,625, respectively.
    

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 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 Trustees. 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.
    


                                       18
<PAGE>

   
     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 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
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 $25,720, $618,040 and $1,076,184 in contingent
deferred sales charges from Class B for the period June 26, 1996 (commencement
of operations) through September 30, 1996 and for the fiscal years ended
September 30, 1997 and 1998, respectively, (b) approximately $12 and $4,960 in
contingent deferred sales charges from Class C for the fiscal years ended
September 30, 1997 and 1998, respectively, and (c) approximately $14,418 and
$99,718 in front-end sales charges from Class A for the fiscal years ended
September 30, 1997 and 1998, respectively, none of which was retained by the
Distributor. No contingent deferred sales charges were received from Class A
during the fiscal years ended September 30, 1997 and 1998.
    

     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 vote of the Trustees of the Fund on April 17,
1996 at a meeting of the Trustees called for the purpose of voting on such
Plan. The vote included the vote of a majority 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"). In making their decision to adopt the Plan, the
Trustees requested from the Distributor and received such information as they
deemed necessary to make an informed determination as to whether or not
adoption of the Plan was in the best interests of the shareholders of the Fund.
After due consideration of the information received, the Trustees, including
the Independent 12b-1 Trustees, determined that adoption of the Plan would
benefit the shareholders of the Fund. MSDW Advisors, as then sole shareholder
of the
    


                                       19
<PAGE>

Fund, approved the Plan on April 17, 1996, whereupon the Plan went into effect.
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.

   
     Pursuant to the Plan and as required by Rule 12b-1, the Trustees will
receive and review promptly after the end of each calendar quarter a written
report provided by the Distributor of the amounts expended by the Distributor
under the Plan and the purpose for which such expenditures were made. The Fund
accrued amounts payable to the Distributor under the Plan, during the fiscal
year ended September 30, 1998 of $3,886,869. This is an accrual at an annual
rate of 0.88% of the Fund's average daily net assets and was calculated
pursuant to clause (a) of the compensation formula of the plan. This amount is
treated by the Fund as an expense in the year it is accrued. For the fiscal
year ended September 30, 1998, Class A and Class C shares of the Fund accrued
payments under the Plan amounting to $18,844 and $41,480, respectively, which
amounts are equal to 0.25% and 1.00% 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).
    


                                       20
<PAGE>

   
     The gross sales credit is a charge which reflects commissions paid by DWR
to its Financial Advisors and 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 shares sales. Payments may also
be made with respect to distribution expenses incurred in connection with the
distribution of shares, including personal services to shareholders with
respect to holdings of such shares, of an investment company whose assets are
acquired by the Fund in a tax-free reorganization. The distribution fee that
the Distributor receives from the Fund under the Plan, in effect, offsets
distribution expenses incurred 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 sales 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 or 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 or 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,
$26,595,881 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)
8.56% ($2,277,144)--advertising and promotional expenses; (ii) 0.89%
($236,404)--printing of prospectuses for distribution to other than current
shareholders; and (iii) 90.55% ($24,082,333)--other expenses, including the
gross sales credit and the carrying charge, of which 5.54% ($1,334,253)
represents carrying charges, 38.63% ($9,303,965) represents commission credits
to DWR branch offices for payments of commissions to Morgan Stanley Dean Witter
Financial Advisors or other selected broker-dealer representatives and 55.83%
($13,444,115) represents overhead and other branch office distribution-related
expenses. The term "overhead and other branch office distribution-related
expenses" represents (a) the expenses of operating DWR's branch offices in
connection with the sale of Fund shares, including lease costs, the
    


                                       21
<PAGE>

   
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 share sales. 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 in
distribution shares of the Fund may be more or less than the total of (i) the
payments made by the Fund pursuant to the Plan and (ii) the proceeds of
contingent deferred sales charges paid by investors upon redemption of shares.
The Distributor has advised the Fund that in the case of Class B shares the
excess distribution expenses, including the carrying charge designed to
approximate the opportunity costs incurred by DWR which arise from it having
advanced monies without having received the amount of any sales charges imposed
at the time of sale of the Fund's Class B shares, totalled $18,378,964 at
September 30, 1998. Because there is no requirement under the Plan that the
Distributor be reimbursed for all 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 distribution expenses in excess of payments made
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 or
indirect 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 April 30, 1997 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 of the shareholders of the
affected Class or Classes of the Fund, and all material amendments of 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) or 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


                                       22
<PAGE>

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.

   
     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 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 value of all assets of
the Fund, subtracting its liabilities, dividing by the number of shares
outstanding and adjusting to the nearest cent. 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.
    


                                       23
<PAGE>

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

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

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

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


                                       24
<PAGE>

   
     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 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:

     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 the Distributor 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 Income Builder Fund or
in another Class of Morgan Stanley Dean Witter Income Builder Fund. 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.
    


                                       26
<PAGE>

   
     Investment of Dividends or Distributions Received in Cash. As discussed in
the Prospectus, any shareholder who receives a cash payment representing a
dividend or distribution may invest such dividend or distribution in shares of
the applicable Class at net asset value, without the imposition of a CDSC upon
redemption, by returning the check or the proceeds to the Transfer Agent within
30 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 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, 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.

     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).
    


                                       27
<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 in 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 Income Builder Fund, 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 each Class of shares
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
    


                                       28
<PAGE>

   
of the exchange. During the period of time the shareholder remains in the
Exchange Fund (calculated from the last day of the month in which the Exchange
Fund shares were acquired), the holding period or "year since purchase payment
made" is frozen. When shares are redeemed out of the Exchange Fund, they will
be subject to a CDSC which would be based upon the period of time the
shareholder held shares in a 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,


                                       29
<PAGE>

redemptions or repurchases, the Transfer Agent shall be liable for its own
negligence and not for the default or negligence of its correspondents or for
losses in transit. The Fund shall not be liable for any default or negligence
of the Transfer Agent, the Distributor or any selected broker-dealer.

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

   
     Exchanges are subject to the minimum investment requirement and any other
conditions imposed by each fund. (The minimum initial investment for the
Exchange Privilege account of each Class is $5,000 for 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, at their discretion, accept initial investments of as low as $1,000.
The minimum 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


                                       30
<PAGE>

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") after it receives the request, and
certificate, if any, in good order. Any redemption request received after such
computation will be redeemed at the next determined net asset value. The term
good order means that the share certificate, if any, and request for redemption
are properly signed, accompanied by any documentation required by the Transfer
Agent, and bear signature guarantees when required by the Fund or 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 supplement to the 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,
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). 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 of 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.


                                       31
<PAGE>

     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 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 the proceeds, is
received by the Transfer Agent.

     Exercise of the reinstatement privilege will not affect the federal income
tax and state 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 and state personal 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 under "Dividends, Distributions and Taxes,"
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 shareholders at
year-end will be able to claim their share of the tax paid by the Fund as a
credit against their individual federal income tax. Shareholders will increase
their tax basis of Fund shares owned by an amount equal, under current law, to
65% of the amount of undistributed capital gains.

     Because the Fund intends to distribute substantially all of its net
investment income and net capital gains to shareholders and otherwise qualify
as a regulated investment company under Subchapter M of the Internal Revenue
Code it is not expected that the Fund will be required to pay any federal
income tax. Shareholders 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 the 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. Dividend payments will be eligible for the federal dividends received
deduction available to the Fund's corporate shareholders only to the extent the
aggregate dividends received by the Fund would be eligible for the deduction if
the Fund were the shareholder claiming the dividends received deduction. The
amount of dividends paid by the Fund which may qualify for the dividends
received deduction is limited to the aggregate amount of qualifying dividends
which the Fund derives from its portfolio investments which the Fund has held
for a minimum period, usually 46 days 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.

     Gains or losses on sales of securities by the Fund will be long-term
capital gains or losses if the securities have a tax holding period of more
than twelve months. Gains or losses on the sale of securities with a tax
holding period of twelve months or less will be short-term gains or losses.

   
     Distributions of net long-term capital gains, if any, are taxable to
shareholders as long-term capital gains regardless of how long a shareholder
has held the Fund's shares and regardless of whether the distribution is
received in additional shares or in cash. Capital gains distributions are not
eligible for the dividends received deduction. It is expected that the Treasury
will issue regulations or other guidance to permit shareholders to take into
account their proportionate share of the Fund's capital gains distributions
that will be subject to a reduced rate under the Taxpayer Relief Act of 1997.
The Taxpayer Relief Act reduced the maximum tax rate on long term capital gains
from 28% to 20%; however, it also lengthened the required holding period to
obtain the lower rate from more than 12 months to more than
    


                                       32
<PAGE>

   
18 months. However, the IRS Restructuring and Reform Act of 1998 reduces 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%.
    

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

     Under current federal tax law, the Fund will receive net investment income
in the form of interest by virtue of holding Treasury bills, notes and bonds,
and will recognize income attributable to it from holding zero coupon Treasury
securities. 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 payment in cash on the security during the year. As an investment
company, the Fund must pay out substantially all of its net investment income
each year. Accordingly, the Fund, to the extent it invests in zero coupon
Treasury securities, may be required to pay out as an income distribution each
year an amount which is greater than the total amount of cash receipts of
interest the Fund actually received. Such distributions will be made from the
available cash of the Fund or by liquidation of portfolio securities if
necessary. If a distribution of cash necessitates the liquidation of portfolio
securities, the Investment Manager will select which securities to sell. The
Fund may realize a gain or loss from such sales. In the event the Fund realizes
net capital gains from such transactions, its shareholders may receive a larger
capital gain distribution, if any, than they would in the absence of such
transactions.

     Any dividend or capital gains distribution received by a shareholder from
any investment company will have the effect of reducing the net asset value of
the shareholder's stock in that company by the exact amount of the dividend or
capital gains distribution. Furthermore, capital gains distributions and some
portion of the 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 the distribution of realized long-term capital
gains, such payment or distribution would be in part a return of capital but
nonetheless would be taxable to the shareholder. Therefore, an investor should
consider the tax implications of purchasing Fund shares immediately prior to a
distribution record date.

   
     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 fiscal year ended September 30, 1998 and for the period June 26, 1996
(commencement of operations) through
    


                                       33
<PAGE>

   
September 30, 1998 were -9.66% and 9.89%, 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 -9.67% and -3.67%, 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 -6.25% and 0.09%,
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 -4.46% and 1.06%, 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
fiscal year ended September 30, 1998 and for the period June 26, 1996
(commencement of operations) through September 30, 1998 were -5.29% and 11.06%,
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 -4.67% and 0.86%, 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 -5.38%
and 0.09%, 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 -4.46% and 1.06%, 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 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 fiscal year ended September 30, 1998 and for
the period June 26, 1996 (commencement of operations) through September 30,
1998 were -5.29% and 26.78%, 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 -4.67% and 1.01%,
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
- -5.38% and 0.10%, 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 -4.46% and 1.25%, 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 to the following amounts at September
30, 1998:

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

     The shareholders of the Fund are entitled to a full vote for each full
share of beneficial interest held. The Fund is authorized to issue an unlimited
number of shares of beneficial interest. 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 (as provided for in
the Declaration of Trust), and they may at any time lengthen or shorten 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. 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 further 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,
the Declaration of Trust provides that a Trustee, officer, employee or agent is
entitled to be indemnified against all liability in connection with the affairs
of the Fund.

     The Fund is authorized to issue an unlimited number of shares of
beneficial interest.

     The Fund shall be of unlimited duration subject to the provisions in the
Declaration of Trust concerning termination by action of the shareholders or
the Trustees.

MORGAN STANLEY DEAN WITTER INCOME BUILDER FUND
NOTES TO FINANCIAL STATEMENTS September 30, 1998
    

1. ORGANIZATION AND ACCOUNTING POLICIES

Morgan Stanley Dean Witter Income Builder Fund (the "Fund"), formerly Dean
Witter Income Builder Fund, is registered under the Investment Company Act of
1940, as amended (the "Act"), as a diversified, open-end management investment
company. The Fund's primary investment objective is to seek reasonable income
and, as a secondary objective, growth of capital. The Fund seeks to achieve its
objective by investing primarily in income-producing equity securities,
including common and preferred stocks as well as convertible securities. The
Fund was organized as a Massachusetts business trust on March 21, 1996 and
commenced operations on June 26, 1996. 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
(in cases where securities are 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); (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); (4) certain portfolio
securities may be valued by an outside pricing service approved by


                                       47

NOTES TO FINANCIAL STATEMENTS September 30, 1998, continued

the Trustees. The pricing service may utilize a matrix system incorporating
security quality, maturity and coupon as the evaluation model parameters,
and/or research and evaluations by its staff, including review of broker-dealer
market price quotations, if available, in determining what it believes is the
fair valuation of the securities valued by such pricing service; and (5)
short-term debt securities having a maturity date of more than sixty days at
time of purchase are valued on a mark-to-market basis until sixty days prior to
maturity and thereafter at amortized cost based on their value on the 61st day.
Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.


B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Dividend income and other distributions are recorded on the ex-dividend date
except for certain dividends on foreign securities which are recorded as soon
as the Fund is informed after 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 ex-dividend date. The amounts 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.

F. ORGANIZATIONAL EXPENSES -- The Investment Manager paid the organizational
expenses of the Fund in the amount of approximately $164,000 which have been
reimbursed for the full amount thereof. Such expenses have been deferred and
are being amortized on the straight-line method over a period not to exceed
five years from the commencement of operations.


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
annual rate of 0.75% to the net assets of the Fund determined as of the close
of each business day. Effective May 1, 1998 the Agreement was amended to reduce
the annual rate to 0.725% of the portion of daily net assets in excess of $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 $18,378,964 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 B and Class C shares of $1,076,184 and $4,960, respectively
and received $99,718 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 year the ended September 30, 1998
aggregated $370,672,491 and $254,895,716, respectively.

For the year ended September 30, 1998, the Fund incurred $141,296 in brokerage
commissions with DWR for portfolio transactions executed on behalf of the Fund.
At September 30, 1998, the Fund's receivable for investments sold and payable
for investments purchased included unsettled trades with DWR of $1,671,518 and
$889,375, respectively.

commissions with Morgan Stanley & Co., Inc., an affiliate of the Investment

Fund.

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 $5,100.

As of September 30, 1998, the Fund had temporary book/tax differences primarily
attributable to capital loss deferrals on wash sales and permanent book/tax
differences attributable to nondeductible expenses. To reflect
reclassifications arising from the permanent differences, paid-in-capital was
charged and accumulated undistributed net investment income was credited
$38,752.

MORGAN STANLEY DEAN WITTER INCOME BUILDER FUND
REPORT OF INDEPENDENT ACCOUNTANTS
    


TO THE SHAREHOLDERS AND TRUSTEES
OF MORGAN STANLEY DEAN WITTER INCOME BUILDER FUND

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 Income
Builder Fund (the "Fund"), formerly Dean Witter Income Builder, 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 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.

           Amendment dated June 22, 1998 to the Declaration of Trust
     (the "Declaration") of Dean Witter Income Builder Fund (the "Trust")
                              dated March 20, 1996


         WHEREAS, the Trust was established by the Declaration on the date
hereinabove set forth under the laws of the Commonwealth of Massachusetts; and

         WHEREAS, the Trustees of the Trust have deemed it advisable to change
the name of the Trust to "Morgan Stanley Dean Witter Income Builder Fund," such
change to be effective on June 22, 1998;

NOW, THEREFORE:

         1. Section 1.1 of Article I of the Declaration is hereby amended so
that that Section shall read in its entirety as follows:

              "Section 1.1. Name. The name of the Trust created hereby is the
              Morgan Stanley Dean Witter Income Builder Fund and so far as may
              be practicable the Trustees shall conduct the Trust's activities,
              execute all documents and sue or be sued under that name, which
              name (and the word "Trust" whenever herein used) shall refer to
              the Trustees as Trustees, and not as individuals, or personally,
              and shall not refer to the officers, agents, employees or
              Shareholders of the Trust. Should the Trustees determine that the
              use of such name is not advisable, they may use such other name
              for the Trust as they deem proper and the Trust may hold its
              property and conduct its activities under such other name."

         2. Subsection (o) 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...

              "(o) "Trust" means the Morgan Stanley Dean Witter Income Builder
              Fund."

         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 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

<PAGE>

              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.

IN WITNESS WHEREOF, the undersigned, the Trustees of the Trust, have executed
this instrument this 22nd day of June, 1998.

                        INVESTMENT MANAGEMENT AGREEMENT

     AGREEMENT made as of the 31st day of May, 1997, and amended as of May 1,
1998, by and between Dean Witter Income Builder Fund, 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

<PAGE>

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 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: 0.75% of daily net assets up to
$500 million and 0.725% 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

                                       2
<PAGE>

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
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

                                       3
<PAGE>

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 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 Income Builder Fund,
dated March 20, 1996, 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 Income
Builder 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 Dean Witter Income Builder 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 said Dean Witter Income Builder Fund, but the Trust Estate only
shall be liable.

     IN WITNESS WHEREOF, the parties hereto have executed and delivered this
Agreement, as amended, on May 1, 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
in this Agreement and that Fund's prospectus and the Distributor hereby accepts
such appointment and agrees to act hereunder. Each Fund, during the term of
this Agreement, shall sell Shares to the Distributor upon the terms and
conditions set forth herein.

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

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

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

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

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


                                       1
<PAGE>

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

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

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

     SECTION 4. Repurchase or Redemption of Shares.

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

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

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

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

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

                                       2
<PAGE>

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

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

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

     SECTION 5. Duties of the Fund.

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

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

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

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

     SECTION 6. Duties of the Distributor.

     (a) The Distributor shall sell shares of each Fund through DWR and may
sell shares through other securities dealers and its own 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 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

<PAGE>

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

              1.1 Subject to the terms and conditions set forth in this
Agreement, the Fund hereby employs and appoints MSDW TRUST to act as, and MSDW

connection with any accumulation, open-account or similar plans provided to the
holders of such Shares ("Shareholders") and set out in the currently effective
prospectus and statement of additional information ("prospectus") of the Fund,

              (viii) Maintain records of account for and advise the Fund and
its Shareholders as to the foregoing; and

              (ix) Record the issuance of Shares of the Fund and maintain

                               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
<PAGE>

     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

                       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

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.
