                   three groupings of fixed-income securities.
- -------------------------------------------------------------------------------
Shares Offered     Shares of beneficial interest with $0.01 par value (see page
                   31). The Fund offers four Classes of shares, each with a
                   different combination of sales charges, ongoing fees and

                   securities, U.S. Treasury securities and U.S. Government
                   Agency securities; and 3. high yield, high risk fixed-income
                   securities, primarily rated Baa/BBB or lower, and non-rated
                   securities of comparable quality. (see pages 6-18).
- -------------------------------------------------------------------------------
Investment         Dean Witter InterCapital Inc. ("InterCapital"), the
Manager            Investment Manager of the Fund, and its wholly-owned
                   subsidiary, Dean Witter Services Company Inc., serve in
                   various investment management, advisory, management and
                   administrative capacities to 100 investment companies and
                   other portfolios with assets of approximately $96.6 billion
                   at June 30, 1997 (see page 6).
- -------------------------------------------------------------------------------
Management Fee     The Investment Manager receives a monthly fee at the annual
                   rate of 0.40% of daily net assets (see page 6).
- -------------------------------------------------------------------------------
Distributor and    Dean Witter Distributors Inc. (the "Distributor"). The Fund
Distribution Fee   has adopted a distribution plan pursuant to Rule 12b-1 under
                   the Investment Company Act (the "12b-1 Plan") with respect
                   to the distribution fees paid by the Class A, Class B and
                   Class C shares of the Fund to the Distributor. The entire
                   12b-1 fee payable by Class A and a portion of the 12b-1 fee
                   payable by each of Class B and Class C equal to 0.20% of the
                   average daily net assets of Class B and 0.25% of the average
                   daily net assets of Class C 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 25).
- -------------------------------------------------------------------------------
Alternative        Four classes of shares are offered: 
Purchase             
Arrangements       o Class A shares are offered with a front-end sales charge,
                   starting at 4.25% 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, 21 and 25).

                   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 0.85% of the lesser of: (a) the average
                   daily net sales of the Fund's Class B shares or (b) the
                   average daily net assets of Class B. All shares of the Fund
                   held prior to July 28, 1997 have been designated Class B
                   shares. Shares held before May 1, 1997 will convert to Class
                   A shares in May, 2007. In all other instances, Class B
                   shares convert to Class A shares approximately ten years
                   after the date of the original purchase (see pages 18, 23
                   and 25).

                   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 0.85% of average daily net assets of the Class (see pages
                   18, 24 and 25).

                   o Class D shares are offered only to investors meeting an
                   initial investment minimum of $5 million and to certain
                   other limited categories of investors. Class D shares are
                   offered without a front-end sales charge or CDSC and are not
                   subject to any 12b-1 fee (see pages 18 and 25). Dividends
                   and Dividends from net investment income are declared and
                   paid monthly. Capital gains distributions, if any, are paid
                   Capital Gains at least once a year or are retained for
                   reinvestment by the Fund. Dividends and capital gains
                   distributions paid Distributions on shares of a Class are
                   automatically invested 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 27 and 30).
- -------------------------------------------------------------------------------
Redemption         Shares are redeemable by the shareholder at net asset value
                   less any applicable CDSC on Class A, Class B or Class C
                   shares. An account may be involuntarily redeemed if the
                   total value of the account is less than $100 or, if the
                   account was opened through EasyInvest(Service Mark), if
                   after twelve months the shareholder has invested less than
                   $1,000 in the account. (see page 29).
- -------------------------------------------------------------------------------
Risks              The value of the Fund's portfolio securities, and therefore
                   the net asset value of the Fund's shares, may increase or
                   decrease due to various factors, principally changes in
                   prevailing interest rates. Generally, a rise in interest
                   rates will result in a decrease in net asset value, while a
                   drop in interest rates will result in an increase in net
                   asset value. Mortgage-backed securities are subject to
                   prepayments or refinancings of the mortgage pools underlying
                   such securities which may have an impact upon the yield and
                   the net asset value of the Fund's shares. Asset-backed
                   securities involve risks resulting mainly from the fact that
                   such securities do not usually contain the complete benefit
                   of a security interest in the related collateral. Certain of
                   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 the higher rated lower yielding
                   fixed-income securities. The foreign securities and markets
                   in which the Fund will invest pose different and generally
                   greater risks than those risks customarily associated with
                   domestic securities and markets including fluctuations in
                   foreign currency exchange rates, foreign tax rates and
                   foreign securities exchange controls. The Fund may enter
                   into repurchase agreements and reverse repurchase
                   agreements, may purchase securities on a when-issued and
                   delayed delivery basis and may utilize certain investment
                   techniques including options and futures for hedging
                   purposes all of which involve certain special risks (see
                   pages 6 through 18).

  The above is qualified in its entirety by the detailed information appearing
  elsewhere in the Prospectus and in the Statement of Additional Information.

- --------------
(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 0.20% of the average daily net assets 
       of Class B and 0.25% of the average daily net assets of Class C 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 0.85% distribution fee (see 
       "Purchase of Fund Shares--Alternative Purchase Arrangements"). 
(7)    There were no outstanding shares of Class A, Class C or Class D prior 
       to the date of this Prospectus. Accordingly, "Total Fund Operating 
       Expenses," as shown above with respect to those Classes, are based upon 
       the sum of 12b-1 Fees, Management Fees and estimated "Other Expenses."

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

Dean Witter Diversified Income Trust (the "Fund") is an open-end diversified
management investment company. The Fund is a trust of the type commonly known
as a "Massachusetts business trust" and was organized under the laws of The
Commonwealth of Massachusetts on December 20, 1991.

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

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

   The Fund has retained the Investment Manager to provide administrative 
services, manage its business affairs and manage the investment of the Fund's 
assets, including the placing of orders for the purchase and sale of 
portfolio securities. InterCapital has retained Dean Witter Services Company 
Inc. to perform the aforementioned administrative services for the Fund. The 
Fund's 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 0.40% to the Fund's net assets determined as of the close of 
each business day. For the fiscal year ended October 31, 1996, the Fund 
accrued total compensation to the Investment Manager amounting to 0.40% of 
the Fund's average daily net assets and the Fund's total expenses amounted to 
1.42% of the Fund's average daily net assets. 

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

The primary investment objective of the Fund is to provide a high level of
current income. As a secondary objective the Fund seeks to maximize total
return but only to the extent consistent with its primary objective. The
investment objectives of the Fund are fundamental policies and may not be
changed without the approval of the holders of a majority of the Fund's shares.
There is no assurance that the Fund's investment objectives will be achieved.

   The Fund will seek to achieve its investment objectives by investing at 
least 65% of its total assets in fixed-income securities and by equally 
allocating, under normal circumstances, an approximately one-third portion of 
its total assets among three separate groupings of various types of 
fixed-income securities. The Investment Manager will adjust the Fund's assets 
not less than quarterly to reflect any changes in the relative values of the 
securities in each grouping so that following the adjustment the value of the 
Fund's investments in each grouping will be equal to the extent practicable. 

   The three groupings in which the Fund will invest its total assets are as 
follows: 

   1. High quality fixed-income securities issued or guaranteed by the U.S. 
Government, its agencies or instrumentalities (including zero coupon 
securities) or high quality fixed income securities issued or guaranteed by a 
foreign government or supranational organization or any of their political 
subdivisions, authorities, agencies or instrumentalities or fixed income 
securities issued by a corporation, all of which are rated AAA or AA by 
Standard & Poor's Corporation ("S&P") or Aaa or Aa by Moody's Investors 
Service, Inc. ("Moody's") or, if unrated, are determined by the Investment 
Manager to be of equivalent quality; in certificates of deposit and bankers' 
acceptances issued or guaranteed by, or time deposits maintained at, banks 
(including foreign branches of U.S. banks or U.S. or foreign branches of 
foreign banks) having total assets of more than $500 million and determined 
by the Investment Manager to be of high creditworthiness; commercial paper 
rated A-1 or A-2 by S&P, Prime-1 or Prime-2 by Moody's or Duff 1 or Duff 2 by 
Duff & Phelps Inc. or, if unrated, issued by U.S. or foreign companies having 
outstanding debt securities rated A or higher by S&P or Moody's; and in loan 
participation interests 

6

<PAGE>

having a remaining term not exceeding one year in loans extended by banks to 
such companies. Certain foreign securities purchased by the Fund will not 
have received ratings by a recognized U.S. rating agency. In such cases the 
Investment Manager will review the issuers of such securities with respect to 
the quality of their management, balance sheet and financial ratios, cash 
flows and earnings to establish that the securities purchased by the Fund are 
of a comparable quality to issuers receiving high quality ratings by a 
recognized U.S. rating agency. All of the securities described above will 
have remaining maturities, at the time of purchase, of not more than three 
years. 

   The Investment Manager will actively manage the Fund's assets in this 
grouping in accordance with a global market strategy (see "Investment 
Objective and Policies--Portfolio Management," in the Prospectus). Consistent 
with such a strategy, the Investment Manager intends to allocate the Fund's 
investments among securities denominated in the currencies of a number of 
foreign countries and, within each such country, among different types of 
debt securities. The Investment Manager will adjust the Fund's exposure to 
different currencies based on its perception of the most favorable markets 
and issuers. In allocating the Fund's assets among various markets, the 
Investment Manager will assess the relative yield and anticipated direction 
of interest rates in particular markets, the level of inflation, liquidity 
and financial soundness of each market, and the general market and economic 
conditions existing in each market as well as the relationship of currencies 
of various countries to the U.S. dollar and to each other. In its 
evaluations, the Investment Manager will utilize its internal financial, 
economic and credit analysis resources as well as information obtained from 
other sources. 

   A portion of the Fund's investments in securities of U.S. issuers are 
likely to be in commercial paper, bankers acceptances and other short-term 
debt instruments issued by U.S. corporations. However, at times during which 
there exists large-scale political or economic uncertainty, the Fund is 
likely to increase its investments in U.S. Government securities (including 
zero coupon securities). In such cases, the securities which the Fund is most 
likely to purchase are U.S. Treasury bills and U.S. Treasury notes with 
remaining maturities of under three years, both of which are direct 
obligations of the U.S. Government. The Fund may also purchase securities 
issued by various agencies and instrumentalities of the U.S. Government. 
These will include obligations backed by the full faith and credit of the 
United States (such as those issued by the Government National Mortgage 
Association); obligations whose issuing agency or instrumentality has the 
right to borrow, to meet its obligations, from an existing line of credit 
with the U.S. Treasury (such as those issued by the Federal National Mortgage 
Association); and obligations backed by the credit of the issuing agency or 
instrumentality (such as those issued by the Federal Farm Credit System). 

   The securities in which the Fund will be investing may be denominated in 
any currency or multinational currency, including the U.S. dollar. In 
addition to the U.S. dollar, such currencies will include, among others: the 
Australian dollar; Deutsche mark; Japanese yen; French franc; British pound; 
Canadian dollar; Swiss franc; Dutch guilder; Austrian schilling; Spanish 
peseta; Swedish krona; and European Currency Unit ("ECU"). 

   The Fund may invest, without limitation in this grouping, in notes and 
commercial paper, the principal amount of which is indexed to certain 
specific foreign currency exchange rates. Indexed notes and commercial paper 
typically provide that their principal amount is adjusted upwards or 
downwards (but not below zero) at maturity to reflect fluctuations in the 
exchange rate between two currencies during the period the obligation is 
outstanding, depending on the terms of the specific security. In selecting 
the two currencies, the Investment Manager will consider the correlation and 
relative yields of various currencies. The Fund will purchase an indexed 
obligation using the currency in which it is denominated and, at maturity, 
will receive interest and principal payments thereon in that currency. The 
amount of principal payable by the issuer at maturity, however, will vary 
(i.e., increase or decrease) in response to the change (if any) in the 
exchange rates between the two specified currencies during the period from 
the date the instrument is issued to its maturity date. The potential for 
realizing gains as a result of changes in foreign currency exchange rates may 
enable the Fund to hedge the currency in which the obligation is denominated 
(or to effect cross-hedges against other currencies) against a decline in the 
U.S. dollar value of investments denominated in foreign currencies, while 
providing an attractive money market rate of return. The Fund will purchase 
such indexed obligations to generate current income or for hedging purposes 
and will not speculate in such obligations. 

   As indicated above, the Fund may invest in securities denominated in a 
multi-national currency unit. An illustration of a multi-national currency 
unit is the ECU, which is a "basket" consisting of specified amounts of the 
currencies of the member states of the European Community, a Western European 
economic cooperative organization that includes, among other countries, 
France, West Germany, The Netherlands and the United Kingdom. The specific 
amounts of currencies comprising the ECU may be adjusted by the Council of 
Ministers of the European Community to reflect changes in relative values of 
the underlying currencies. The Investment Manager does not believe that such 
adjustments will adversely 

                                                                              7

<PAGE>

affect holders of ECU-denominated obligations or the marketability of such 
securities. European supranational entities, in particular, issue 
ECU-denominated obligations. The Fund may invest in securities denominated in 
the currency of one nation although issued by a governmental entity, 
corporation or financial institution of another nation. For example, the Fund 
may invest in a British pound-denominated obligation issued by a United 
States corporation. Such investments involve credit risks associated with the 
issuer and currency risks associated with the currency in which the 
obligation is denominated. 

   2. (i) Fixed-rate and adjustable rate mortgage-backed securities 
("Mortgage-Backed Securities") which are issued or guaranteed by the United 
States Government, its agencies or instrumentalities or by private issuers 
which are rated Aaa by Moody's or AAA by S&P or, if not rated, are determined 
to be of comparable quality by the Investment Manager; (ii) securities backed 
by other assets such as automobile or credit card receivables and home equity 
loans ("Asset-Backed Securities") which are rated Aaa by Moody's or AAA by 
S&P or, if not rated are determined to be of comparable quality by the 
Investment Manager; (iii) U.S Treasury securities (bills, notes, bonds and 
zero coupon securities) (without restrictions as to remaining maturity at 
time of purchase) and (iv) U.S. Government agency securities (discount notes, 
medium-term notes, debentures and zero coupon securities) (without 
restrictions as to remaining maturity at time of purchase). The term 
Mortgage-Backed Securities as used herein includes adjustable rate mortgage 
securities and derivative mortgage products such as collateralized mortgage 
obligations and stripped mortgage-backed securities, all as described below. 

   There are currently three basic types of Mortgage-Backed Securities: (i) 
those issued or guaranteed by the United States Government or one of its 
agencies or instrumentalities, such as the Government National Mortgage 
Association ("GNMA"), the Federal National Mortgage Association ("FNMA") and 
the Federal Home Loan Mortgage Corporation ("FHLMC") (securities issued by 
GNMA, but not those issued by FNMA or FHLMC, are backed by the "full faith 
and credit" of the United States); (ii) those issued by private issuers that 
represent an interest in or are collateralized by Mortgage-Backed Securities 
issued or guaranteed by the United States Government or one of its agencies 
or instrumentalities; and (iii) those issued by private issuers that 
represent an interest in or are collateralized by whole mortgage loans or 
Mortgage-Backed Securities without a government guarantee but usually having 
some form of private credit enhancement. 

   The Fund will invest in mortgage pass-through securities representing 
participation interests in pools of residential mortgage loans originated by 
United States governmental or private lenders such as banks, broker-dealers 
and financing corporations and guaranteed, to the extent provided in such 
securities, by the United States Government or one of its agencies or 
instrumentalities. Such securities, which are ownership interests in the 
underlying mortgage loans, differ from conventional debt securities, which 
provide for periodic payment of interest in fixed amounts (usually 
semiannually) and principal payments at maturity or on specified call dates. 
Mortgage pass-through securities provide for monthly payments that are a 
"pass-through" of the monthly interest and principal payments (including any 
prepayments) made by the individual borrowers on the pooled mortgage loans, 
net of any fees paid to the guarantor of such securities and the servicer of 
the underlying mortgage loans. 

   The guaranteed mortgage pass-through securities in which the Fund may 
invest include those issued or guaranteed by GNMA, FNMA and FHLMC. GNMA 
certificates are direct obligations of the U.S. Government and, as such, are 
backed by the "full faith and credit" of the United States. FNMA is a 
federally chartered, privately owned corporation and FHLMC is a corporate 
instrumentality of the United States. FNMA and FHLMC certificates are not 
backed by the full faith and credit of the United States, but the issuing 
agency or instrumentality has the right to borrow, to meet its obligations, 
from an existing line of credit with the U.S. Treasury. The U.S. Treasury has 
no legal obligation to provide such line of credit and may choose not to do 
so. 

   Certificates for Mortgage-Backed Securities evidence an interest in a 
specific pool of mortgages. These certificates are, in most cases, "modified 
pass-through" instruments, wherein the issuing agency guarantees the payment 
of principal and interest on mortgages underlying the certificates, whether 
or not such amounts are collected by the issuer on the underlying mortgages. 

ADJUSTABLE RATE MORTGAGE SECURITIES. The Fund may also invest in adjustable 
rate mortgage securities ("ARMs"), which are pass-through mortgage securities 
collateralized by mortgages with adjustable rather than fixed rates. ARMs 
eligible for inclusion in a mortgage pool generally provide for a fixed 
initial mortgage interest rate for either the first three, six, twelve or 
thirteen scheduled monthly payments. Thereafter, the interest rates are 
subject to periodic adjustment based on changes to a designated benchmark 
index. 

   ARMs contain maximum and minimum rates beyond which the mortgage interest 
rate may not vary over the lifetime of the security. In addition, certain 
ARMs provide for additional limitations on the maximum amount by which the 
mortgage interest rate may adjust for any single adjustment period. 
Alternatively, certain ARMs 

8

<PAGE>

contain limitations on changes in the required monthly payment. In the event 
that a monthly payment is not sufficient to pay the interest accruing on an 
ARM, any such excess interest is added to the principal balance of the 
mortgage loan, which is repaid through future monthly payments. If the 
monthly payment for such an instrument exceeds the sum of the interest 
accrued at the applicable mortgage interest rate and the principal payment 
required at such point to amortize the outstanding principal balance over the 
remaining term of the loan, the excess is utilized to reduce the then 
outstanding principal balance of the ARM. 

PRIVATE MORTGAGE PASS-THROUGH SECURITIES. Private mortgage pass-through 
securities are structured similarly to the GNMA, FNMA and FHLMC mortgage 
pass-through securities and are issued by originators of and investors in 
mortgage loans, including savings and loan associations, mortgage banks, 
commercial banks, investment banks and special purpose subsidiaries of the 
foregoing. These securities usually are backed by a pool of conventional 
fixed rate or adjustable rate mortgage loans. Since private mortgage 
pass-through securities typically are not guaranteed by an entity having the 
credit status of GNMA, FNMA and FHLMC, such securities generally are 
structured with one or more types of credit enhancement. 

COLLATERALIZED MORTGAGE OBLIGATIONS AND MULTICLASS PASS-THROUGH 
SECURITIES. Collateralized mortgage obligations or "CMOs" are debt 
obligations collateralized by mortgage loans or mortgage pass-through 
securities. Typically, CMOs are collateralized by GNMA, FNMA or FHLMC 
Certificates, but also may be collateralized by whole loans or private 
mortgage pass-through securities (such collateral collectively hereinafter 
referred to as "Mortgage Assets"). Multiclass pass-through securities are 
equity interests in a trust composed of Mortgage Assets. Payments of 
principal of and interest on the Mortgage Assets, and any reinvestment income 
thereon, provide the funds to pay debt service on the CMOs or make scheduled 
distributions on the multiclass pass-through securities. CMOs may be issued 
by agencies or instrumentalities of the United States government, or by 
private originators of, or investors in, mortgage loans, including savings 
and loan associations, mortgage banks, commercial banks, investment banks and 
special purpose subsidiaries of the foregoing. The issuer of a series of CMOs 
may elect to be treated as a Real Estate Mortgage Investment Conduit 
("REMIC"). REMICs include governmental and/or private entities that issue a 
fixed pool of mortgages secured by an interest in real property. REMICs are 
similar to CMOs in that they issue multiple classes of securities, but unlike 
CMOs, which are required to be structured as debt securities, REMICs may be 
structured as indirect ownership interests in the underlying assets of the 
REMICs themselves. However, there are no effects on the Fund from investing 
in CMOs issued by entities that have elected to be treated as REMICs, and all 
future references to CMOs shall also be deemed to include REMICs. In 
addition, in reliance upon a recent interpretation by the staff of the 
Securities and Exchange Commission, the Fund may invest without limitation in 
CMOs and other Mortgage-Backed Securities which are not by definition 
excluded from the provisions of the Investment Company Act of 1940, as 
amended, and which have obtained exemptive orders from such provisions from 
the Securities and Exchange Commission. 

   In a CMO, a series of bonds or certificates is issued in multiple classes. 
Each class of CMOs, often referred to as a "tranche", is issued at a specific 
fixed or floating coupon rate and has a stated maturity or final distribution 
date. Principal prepayments on the Mortgage Assets may cause the CMOs to be 
retired substantially earlier than their stated maturities or final 
distribution dates. Interest is paid or accrues on all classes of the CMOs on 
a monthly, quarterly or semi-annual basis. Certain CMOs may have variable or 
floating interest rates and others may be stripped (securities which provide 
only the principal or interest feature of the underlying security). 

   The principal of and interest on the Mortgage Assets may be allocated 
among the several classes of a CMO series in a number of different ways. 
Generally, the purpose of the allocation of the cash flow of a CMO to the 
various classes is to obtain a more predictable cash flow to the individual 
tranches than exists with the underlying collateral of the CMO. As a general 
rule, the more predictable the cash flow is on a CMO tranche, the lower the 
anticipated yield will be on that tranche at the time of issuance relative to 
prevailing market yields on Mortgage-Backed Securities. As part of the 
process of creating more predictable cash flows on most of the tranches in a 
series of CMOs, one or more tranches generally must be created that absorb 
most of the volatility in the cash flows on the underlying mortgage loans. 
The yields on these tranches are generally higher than prevailing market 
yields on Mortgage-Backed Securities with similar maturities. As a result of 
the uncertainty of the cash flows of these tranches, the market prices of and 
yield on these tranches generally are more volatile. 

   The Fund also may invest in, among other things, parallel pay CMOs and 
Planned Amortization Class CMOs ("PAC Bonds"). Parallel pay CMOs are 
structured to provide payments of principal on each payment date to more than 
one class. These simultaneous payments are taken into account in calculating 
the stated maturity date 

                                                                              9

<PAGE>

or final distribution date of each class, which, as with other CMO 
structures, must be retired by its stated maturity date or final distribution 
date but may be retired earlier. PAC Bonds generally require payments of a 
specified amount of principal on each payment date. PAC Bonds always are 
parallel pay CMOs with the required principal payment on such securities 
having the highest priority after interest has been paid to all classes. 

STRIPPED MORTGAGE-BACKED SECURITIES.  Stripped Mortgage-Backed Securities are 
derivative multiclass mortgage securities. Stripped Mortgage-Backed 
Securities may be issued by agencies or instrumentalities of the United 
States Government, or by private originators of, or investors in, mortgage 
loans, including savings and loan associations, mortgage banks, commercial 
banks, investment banks and special purpose subsidiaries of the foregoing. 

   Stripped Mortgage-Backed Securities usually are structured with two 
classes that receive different proportions of the interest and principal 
distribution on a pool of Mortgage Assets. A common type of Stripped 
Mortgage-Backed Securities will have one class receiving some of the interest 
and most of the principal from the Mortgage Assets, while the other class 
will receive most of the interest and the remainder of the principal. In the 
most extreme case, one class will receive all of the interest (the 
interest-only or "IO" class), while the other class will receive all of the 
principal (the principal-only or "PO" class). PO classes generate income 
through the accretion of the deep discount at which such securities are 
purchased, and, while PO classes do not receive periodic payments of 
interest, they receive monthly payments associated with scheduled 
amortization and principal prepayment from the Mortgage Assets underlying the 
PO class. The yield to maturity on an IO class is extremely sensitive to the 
rate of principal payments (including prepayments) on the related underlying 
Mortgage Assets, and a rapid rate of principal repayments may have a material 
adverse effect on the Fund's yield to maturity. If the underlying Mortgage 
Assets experience greater than anticipated prepayments of principal, the Fund 
may fail to fully recoup its initial investment in these securities even if 
the securities are rated Aaa by Moody's or AAA by S&P. 

   The Fund may purchase Stripped Mortgage-Backed Securities for income, or 
for hedging purposes to protect the Fund's portfolio against interest rate 
fluctuations. For example, since an IO class will tend to increase in value 
as interest rates rise, it may be utilized to hedge against a decrease in 
value of other fixed-income securities in a rising interest rate environment. 
The Fund understands that the staff of the Securities and Exchange Commission 
considers Stripped Mortgage-Backed Securities representing interest only or 
principal only components of U.S. Government or other debt securities to be 
illiquid securities. The Fund will treat such securities as illiquid so long 
as the staff maintains such a position. The Fund may not invest more than 10% 
of its total assets in illiquid securities. 

ASSET-BACKED SECURITIES. The securitization techniques used to develop 
Mortgage-Backed Securities are also applied to a broad range of other assets. 
Through the use of trusts and special purpose corporations, various types of 
assets, primarily automobile and credit card receivables and home equity 
loans, are being securitized in pass-through structures similar to the 
mortgage pass-through structures described above or in a pay-through 
structure similar to the CMO structure. 

   New instruments and variations of existing Mortgage-Backed Securities and 
Asset-Backed Securities continue to be developed. The Fund may invest in any 
such instruments or variations as may be developed, to the extent consistent 
with its investment objectives and policies and applicable regulatory 
requirements. 

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 generally 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. 

   3. High yield, high risk fixed-income securities rated Baa or lower by 
Moody's or BBB or lower by S&P or, if not rated, are determined by the 
Investment Manager to be of comparable quality. The high yield, high risk 
fixed-income securities in this grouping may include both convertible and 
nonconvertible debt securities and preferred stock. Fixed-income securities 
rated Baa by 

10

<PAGE>

Moody's or BBB by S&P 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. Furthermore, the Fund does not have any minimum 
quality rating standard for its investments. As such, the Fund may invest in 
securities rated as low as Caa, Ca or C by Moody's or CCC, CC, C or C1 by 
Standard & Poor's. Fixed-income securities rated Caa or Ca by Moody's may 
already be in default on payment of interest or principal, while bonds rated 
C by Moody's, their lowest bond rating, can be regarded as having extremely 
poor prospects of ever attaining any real investment standing. Bonds rated C1 
by S&P, their lowest bond rating, are no longer making interest payments. 

   During temporary defensive periods when market conditions warrant 
reduction of some or all of the Fund's securities holdings or when 
temporarily holding cash pending investment, this portion of the Fund may 
invest in U.S. Treasury securities or other money market instruments. Under 
such circumstances the money market instruments in which this portion of the 
Fund may invest, in addition to U.S. Treasury securities (bills, notes, bonds 
and zero coupons securities), are American bank obligations, such as 
certificates of deposit; Eurodollar certificates of deposit; obligations of 
American savings institutions; and commercial paper of American issuers rated 
within the two highest grades by Moody's or S&P or, if not rated, are issued 
by a company having an outstanding debt issue rated at least AA by S&P or Aa 
by Moody's. 

   A description of corporate bond ratings is contained in the Appendix. 
Non-rated securities will also be considered for investment by the Fund when 
the terms of the securities themselves makes them appropriate investments for 
the Fund. 

   The ratings of fixed-income securities by Moody's and S&P 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 objectives 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. 

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. 

   All fixed-income securities are subject to two types of risks: the credit 
risk and the interest rate risk. The credit risk relates to the ability of 
the issuer to meet interest or principal payments or both as they come due. 
Generally, higher yielding fixed-income securities are subject to a credit 
risk to a greater extent than lower yielding fixed-income securities. The 
interest rate risk refers to the fluctuations in the net asset value of any 
portfolio of fixed-income securities resulting from the inverse relationship 
between price and yield of fixed-income securities; that is, when the general 
level of interest rates rises, the prices of outstanding fixed-income 
securities decline, and when interest rates fall, prices rise. 

FOREIGN SECURITIES. Investors should carefully consider the risks of 
investing in securities of foreign issuers and securities denominated in 
non-U.S. currencies. Fluctuations in the relative rates of exchange between 
the currencies of different nations may affect the value of the Fund's 
investments. 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 yield on such assets and the 
net asset value of a share of the Fund as well as the value of the Fund's 
distributions. For example, if a substantial portion of the Fund's assets are 
denominated in Japanese yen and the relative exchange rate of the yen falls 
with respect to the U.S. dollar (i.e., a yen is worth a smaller fraction of a 
dollar than it had been) then the Fund will be receiving a lesser amount of 
interest on its fixed-income securities denominated in yen (when converted 
into U.S. dollars) and when the Fund's assets are valued for purposes of 
determining the net asset value per share of the Fund, the net assets of the 
Fund reflected by the yen-denominated securities will have declined in U.S. 
dollar value and the net asset value of the Fund (always stated in U.S. 
dollars) may have also declined. 

   Foreign currency exchange rates are determined by forces of supply and 
demand on the foreign exchange markets. These forces are themselves affected 
by the international balance of payments and other economic and financial 
conditions, government intervention, speculation and other factors. Moreover, 
foreign currency exchange rates may be affected by the regulatory control of 
the exchanges on which the currencies trade. The foreign currency 
transactions of the Fund will be conducted on a spot basis or through forward 
contracts or futures contracts (see below). The Fund may incur certain costs 
in connection with these currency transactions. 

                                                                             11

<PAGE>

   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 generally 
not subject to uniform accounting, auditing and financial standards and 
requirements comparable to those applicable to U.S. companies. 

   Securities of foreign issuers may be less liquid than comparable 
securities of U.S. issuers and, as such, their price changes may be more 
volatile. Furthermore, foreign exchanges and broker-dealers are generally 
subject to less government and exchange scrutiny and regulation than their 
American counterparts. Brokerage commissions, dealer concessions and other 
transaction costs may be higher on foreign markets than the U.S. In addition, 
differences in clearance and settlement procedures on foreign markets may 
occasion delays in settlements of Fund trades effected in such markets. 
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. 

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

MORTGAGE-BACKED AND ASSET-BACKED SECURITIES. Mortgage-Backed and Asset-Backed 
Securities have certain different characteristics than traditional debt 
securities. Among the major differences are that interest and principal 
payments are made more frequently, usually monthly, and that principal may be 
prepaid at any time because the underlying mortgage loans or other assets 
generally may be prepaid at any time. As a result, if the Fund purchases such 
a security at a premium, a prepayment rate that is faster than expected may 
reduce yield to maturity, while a prepayment rate that is slower than 
expected may have the opposite effect of increasing yield to maturity. 
Alternatively, if the Fund purchases these securities at a discount, faster 
than expected prepayments will increase, while slower than expected 
prepayments may reduce, yield to maturity. The Fund may invest a portion of 
its assets in derivative Mortgage-Backed Securities such as Stripped 
Mortgage-Backed Securities which are highly sensitive to changes in 
prepayment and interest rates. The Investment Manager will seek to manage 
these risks (and potential benefits) by investing in a variety of such 
securities and through hedging techniques. 

   Mortgage-Backed and Asset-Backed Securities, like all fixed income 
securities, generally decrease in value as a result of increases in interest 
rates. In addition, although generally the value of fixed-income securities 
increases during periods of falling interest rates and, as stated above, 
decreases during periods of rising interest rates, as a result of prepayments 
and other factors, this is not always the case with respect to 
Mortgage-Backed and Asset-Backed Securities. 

   Although the extent of prepayments on a pool of mortgage loans depends on 
various economic and other factors, as a general rule prepayments on fixed 
rate mortgage loans will increase during a period of falling interest rates 
and decrease during a period of rising interest rates. Accordingly, amounts 
available for reinvestment by the Fund are likely to be greater during a 
period of declining interest rates and, as a result, likely to be reinvested 
at lower interest rates than during a period of rising interest rates. 
Asset-Backed Securities, although less likely to experience the same 
prepayment rates as Mortgage-Backed Securities, may respond to certain of the 
same factors influencing prepayments, while at other times different factors, 
such as changes in credit use and payment patterns resulting from social, 
legal and economic factors, will predominate. Mortgage-Backed and 
Asset-Backed Securities generally decrease in value as a result of increases 
in interest rates and may benefit less than other fixed income securities 
from declining interest rates because of the risk of prepayment. 

   There are certain risks associated specifically with CMOs. CMOs issued by 
private entities are not U.S. Government securities and are not guaranteed by 
any government agency, although the securities underlying a CMO may be 
subject to a guarantee. Therefore, if the collateral securing the CMO, as 
well as any third party credit support or guarantees, is insufficient to make 
payment, the holder could sustain a loss. However, as stated above, the Fund 
will invest only in CMOs which are rated AAA by S&P or Aaa by Moody's or, if 
unrated, are determined to be of comparable quality. Also, a number of 
different factors, including the extent of prepayment of principal of the 
Mortgage Assets, affect the availability of cash for principal payments by 
the CMO issuer on any payment date and, accordingly, affect the timing of 
principal payments on each CMO class. 

   Asset-Backed Securities involve certain risks that are not posed by 
Mortgage-Backed Securities, resulting mainly from the fact that Asset-Backed 
Securities do not usually contain the complete benefit of a security interest 
in the related collateral. For example, credit card receivables generally are 
unsecured and the debtors are entitled to the protection of a number of state 
and federal consumer credit laws, some of which may reduce the 

12

<PAGE>

ability to obtain full payment. In the case of automobile receivables, due to 
various legal and economic factors, proceeds from repossessed collateral may 
not always be sufficient to support payments on these securities. 

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

HIGH YIELD SECURITIES. Because of the special nature of the Fund's investment 
in high yield securities, commonly known as "junk bonds", the Investment 
Manager must take account of certain special considerations in assessing the 
risks associated with such investments. Although the growth of the high yield 
securities market in the 1980s had paralleled a long economic expansion, 
recently many issuers have been affected by adverse economic and market 
conditions. It should be recognized that an economic downturn or increase in 
interest rates is likely to have a negative effect on the high yield bond 
market and on the value of the high yield securities held by the Fund, as 
well as on the ability of the securities' issuers to repay principal and 
interest on their borrowings. 

   The prices of high yield 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 high yield 
securities and a concomitant volatility in the net asset value of a share of 
the Fund. Moreover, the market prices of certain of the Fund's portfolio 
securities which are structured as zero coupon and payment-in-kind securities 
are affected to a greater extent by interest rate changes and thereby tend to 
be more volatile than securities which pay interest periodically and in cash 
(see "Dividends, Distributions and Taxes" for a discussion of the tax 
ramifications of investments in such securities). 

   The secondary market for high yield securities may be less liquid than the 
markets for higher quality securities and, as such, may have an adverse 
effect on the market prices of certain securities. The limited liquidity of 
the market may also adversely affect the ability of the Fund's Trustees to 
arrive at a fair value for certain high yield securities at certain times and 
could make it difficult for the Fund to sell certain securities. 

   New laws and proposed new laws may have a potentially negative impact on 
the market for high yield bonds. For example, present legislation requires 
federally-insured savings and loan associations to divest their investments 
in high yield bonds. This legislation and other proposed legislation may have 
an adverse effect upon the value of high yield securities and a concomitant 
negative impact upon the net asset value of a share of the Fund. 

   During the fiscal year ended October 31, 1996, 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:

OTHER INVESTMENT POLICIES 

REPURCHASE AGREEMENTS. The Fund may enter into repurchase agreements, which 
may be viewed as a type of secured lending by the Fund, and which typically 
involve the acquisition by the Fund of debt securities from a selling 
financial institution such as a bank, savings and loan association or 
broker-dealer. The agreement provides that the Fund will sell back to the 
institution, and that the institution will repurchase, the underlying 
security at a specified price and at a fixed time in the future, usually not 
more than seven days from the date of purchase. While repurchase agreements 
involve certain risks not associated with direct investments in debt 
securities, the Fund follows procedures designed to minimize those risks. 
These procedures include effecting repurchase transactions only with large, 
well-capitalized and well-established financial institutions whose financial 
condition will be continually monitored by the Investment Manager subject to 
procedures established by the Board of Trustees of the Fund. In addition, the 
value of the collateral underlying the repurchase agreement will be at least 
equal to the repurchase price, including any accrued interest earned on the 
repurchase agreement. 
<PAGE>
REVERSE REPURCHASE AGREEMENTS AND DOLLAR ROLLS. The Fund may also use reverse 
repurchase agreements and dollar rolls as part of its investment strategy. 
Reverse repurchase agreements involve sales by the Fund of portfolio assets 
concurrently with an agreement by the Fund to repurchase the same assets at a 
later date at a fixed price. During the reverse repurchase agreement period, 
the Fund continues to receive principal and interest payments on these 
securities. Generally, the 

                                                                             13

<PAGE>

effect of such a transaction is that the Fund can recover all or most of the 
cash invested in the portfolio securities involved during the term of the 
reverse repurchase agreement, while it will be able to keep the interest 
income associated with those portfolio securities. Such transactions are only 
advantageous if the interest cost to the Fund of the reverse repurchase 
transaction is less than the cost of obtaining the cash otherwise. 

   The Fund may enter into dollar rolls in which the Fund sells securities 
for delivery in the current month and simultaneously contracts to repurchase 
substantially similar (same type and coupon) securities on a specified future 
date. During the roll period, the Fund foregoes principal and interest paid 
on the securities. The Fund is compensated by the difference between the 
current sales price and the lower forward price for the future purchase 
(often referred to as the "drop") as well as by the interest earned on the 
cash proceeds of the initial sale. 

   The Fund will establish a segregated account with its custodian bank in 
which it will maintain cash, U.S. Government securities or other liquid 
portfolio securities equal in value to its obligations in respect of reverse 
repurchase agreements and dollar rolls. Reverse repurchase agreements and 
dollar rolls involve the risk that the market value of the securities the 
Fund is obligated to repurchase under the agreement may decline below the 
repurchase price. In the event the buyer of securities under a reverse 
repurchase agreement or dollar roll files for bankruptcy or becomes 
insolvent, the Fund's use of the proceeds of the agreement may be restricted 
pending a determination by the other party, or its trustee or receiver, 
whether to enforce the Fund's obligation to repurchase the securities. 
Reverse repurchase agreements and dollar rolls are speculative techniques 
involving leverage, and are considered borrowings by the Fund. Under the 
requirements of the Investment Company Act of 1940, as amended (the "Act"), 
the Fund is required to maintain an asset coverage (including the proceeds of 
the borrowings) of at least 300% of all borrowings. The Fund does not expect 
to engage in reverse repurchase agreements and dollar rolls with respect to 
greater than 25% of the Fund's total assets. 

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. 
The securities so purchased are subject to market fluctuation and no interest 
accrues to the purchaser during this period. At the time of delivery of the 
securities, the value may be more or less than the purchase price. There is 
no overall limit on the percentage of the Fund's assets which may be 
committed to the purchase of securities on a when-issued, delayed delivery or 
forward commitment basis. An increase in the percentage of the Fund's assets 
committed to the purchase of securities on a when-issued, delayed delivery or 
forward commitment basis may increase the volatility of the Fund's net asset 
value. 

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

RESTRICTED SECURITIES. The Fund may invest up to 5% of its total assets in 
securities for which there is no readily available market including certain 
of those 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 of 1933, which permits the Fund to sell restricted securities 
to qualified institutional buyers without limitation. The Investment Manager, 
pursuant to procedures adopted by the Trustees of the Fund, will make a 
determination as to the liquidity of each restricted security purchased by 
the Fund. If a restricted security is determined to be "liquid," such 
security will not be included within the category "illiquid securities," 
which under current policy may not exceed 15% of the Fund's total 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 

14

<PAGE>

particular point in time, may be unable to find qualified institutional 
buyers interested in purchasing such securities. 

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 
cash equivalents such as money market instruments, which are maintained in a 
segregated account pursuant to applicable regulations and that are at least 
equal to the market value, determined daily, of the loaned securities. In the 
event the borrower defaults on its obligation to return the loaned 
securities, as a result of bankruptcy or otherwise, the Fund will seek to 
sell the collateral, which action could involve costs or delays. In such case 
the Fund's ability to recover its investment may be restricted or delayed. 

COMMON STOCKS. The Fund may invest in common stocks in an amount up to 20% of 
its total assets in the circumstances described below when consistent with 
the Fund's investment objectives. 

   The Fund may acquire common stocks when attached to or included in a unit 
with fixed-income securities, or when acquired upon conversion of 
fixed-income securities or upon exercise of warrants attached to fixed-income 
securities and may purchase common stocks directly when such acquisitions are 
determined by the Investment Manager to further the Fund's investment 
objectives. 

   For example, the Fund may purchase the common stock of companies involved 
in takeovers or recapitalizations where the issuer, or a controlling 
stockholder, has offered, or pursuant to a "going private" transaction is 
effecting, an exhange of its common stock for newly-issued fixed-income 
securities. By purchasing the common stock of the company issuing the 
fixed-income securities prior to the consummation of the transaction or 
exchange offer, the Fund will be able to obtain the fixed-income securities 
directly from the issuer at their face value, eliminating the payment of a 
dealer's mark-up otherwise payable when fixed-income securities are acquired 
from third parties, thereby increasing the net yield to the shareholders of 
the Fund. While the Fund will incur brokerage commissions in connection with 
its purchase of common stocks, it is anticipated that the amount of such 
commissions will be significantly less than the amount of such mark-up. 

   Fixed-income securities acquired by the Fund through the purchase of 
common stocks under the circumstances described in the preceding paragraph 
are subject to the general credit risks and interest rate risks to which all 
fixed-income securities purchased by the Fund are subject. Such securities 
generally will be rated Baa/BBB or lower as are the other high yield, high 
risk fixed income securities in which the Fund may invest. In addition, since 
corporations involved in takeover situations are often highly leveraged, that 
factor will be evaluated by the Investment Manager as part of its credit risk 
determination with respect to the purchase of particular common stocks for 
the Fund's investment portfolio. In the event the Fund purchases common stock 
of a corporation in anticipation of a transaction (pursuant to which the 
common stock is to be exchanged for fixed-income securities) which fails to 
take place, the Investment Manager will continue to hold such common stocks 
for the Fund's portfolio only if it determines that continuing to hold such 
common stock under those circumstances is consistent with the Fund's 
investment objectives. 

OPTIONS AND FUTURES TRANSACTIONS 

The Fund is permitted to enter into call and put options on its portfolio 
securities, including U.S. Government securities and mortgage-backed 
securities and on various foreign currencies which are listed on several U.S. 
and foreign securities exchanges and are written in over-the-counter 
transactions ("OTC options"). Listed options are issued or guaranteed by the 
exchange on which they trade or by a clearing corporation such as the Options 
Clearing Corporation ("OCC"). The Fund is permitted to write covered call 
options on portfolio securities which are denominated in either U.S. dollars 
or foreign currencies, without limit, in order to hedge against the decline 
in the value of a security or currency in which such security is denominated 
and to close out long call option positions. The Fund may purchase listed and 
OTC call and put options in amounts equalling up to 5% of its total assets. 
The Fund may purchase call options only to close out a covered call position 
or to protect against an increase in the price of a security it anticipates 
purchasing or, in the case of call options on a foreign currency, to hedge 
against an adverse exchange rate change of the currency in which the security 
it anticipates purchasing is denominated vis-a-vis the currency in which the 
exercise price is denominated. The Fund may purchase put options on 
securities which it holds in its portfolio only to protect itself against a 
decline in the value of the security. The Fund may also purchase put options 
to close out written put positions. There are no other limits on the Fund's 
ability to purchase call and put options. 

   The Fund may purchase and sell financial futures contracts that are 
currently traded, or may in the future be traded, on U.S. and foreign 
commodity exchanges on such underlying fixed-income securities as U.S. 
Treasury 

                                                                             15

<PAGE>

bonds, notes, bills, and zero coupon securities, mortgage-backed securities 
and/or any foreign government fixed-income security ("interest rate" 
futures), on various currencies ("currency" futures) and on such indexes of 
U.S. or foreign fixed-income securities as may exist or come into being, such 
as the Moody's Investment Grade Corporate Bond Index ("index" futures). The 
Fund will purchase or sell interest rate futures contracts for the purpose of 
hedging some or all of the value of its portfolio securities (or anticipated 
portfolio securities) against changes in prevailing interest rates. The Fund 
will purchase or sell index futures contracts for the purpose of hedging some 
or all of its portfolio (or anticipated portfolio) securities against changes 
in their prices. 

   The Fund may also purchase and write call and put options on futures 
contracts which are traded on an exchange and enter into closing transactions 
with respect to such options to terminate an existing position. The Fund will 
purchase and write options on futures contracts for identical purposes to 
those set forth above for the purchase of a futures contract and the sale of 
a futures contract or to close out a long or short position in futures 
contracts. 

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

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

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS 

In order to hedge against adverse price movements in the securities held in 
its portfolio and the currencies in which they are denominated (as well as 
the securities it might wish to purchase and their denominated currencies) 
the Fund may engage in transactions in forward foreign currency contracts. A 
forward foreign currency exchange contract ("forward contract") involves an 
obligation to purchase or sell a currency at a future date, which may be any 
fixed number of days from the date of the contract agreed upon by the 
parties, at a price set at the time of the contract. The Fund may enter into 
forward contracts as a hedge against fluctuations in future foreign exchange 
rates. 

   The Fund will enter into forward contracts under various circumstances. 
When the Fund enters into a contract for the purchase or sale of a security 
denominated in a foreign currency, it may, for example, desire to "lock in" 
the price of the security in U.S. dollars or some other foreign currency 
which the Fund is temporarily holding in its portfolio. By entering into a 
forward contract for the purchase or sale, for a fixed amount of dollars or 
other currency, of the amount of foreign currency involved in the underlying 
security transactions, the Fund will be able to protect itself against a 
possible loss resulting from an adverse change in the relationship between 
the U.S. dollar or other currency which is being used for the security 
purchase and the foreign currency in which the security is denominated during 
the period between the date on which the security is purchased or sold and 
the date on which payment is made or received. 

   At other times, when, for example, the Investment Manager believes that 
the currency of a particular foreign country may suffer a substantial decline 
against the U.S. dollar or some other foreign currency, the Fund may enter 
into a forward contract to sell, for a fixed amount of dollars or other 
currency, the amount of foreign currency approximating the value of some or 
all of the Fund's portfolio securities (or securities which the Fund has 
purchased for its portfolio) denominated in such foreign currency. Under 
identical circumstances, the Fund may enter into a forward contract to sell, 
for a fixed amount of U.S. dollars or other currency, an amount of foreign 

16

<PAGE>

currency other than the currency in which the securities to be hedged are 
denominated approximating the value of some or all of the portfolio 
securities to be hedged. This method of hedging, called "cross-hedging," will 
be selected by the Investment Manager when it is determined that the foreign 
currency in which the portfolio securities are denominated has insufficient 
liquidity or are trading at a discount as compared with some other foreign 
currency with which it tends to move in tandem. 

   In addition, when the Fund's Investment Manager anticipates purchasing 
securities at some time in the future, and wishes to lock in the current 
exchange rate of the currency in which those securities are denominated 
against the U.S. dollar or some other foreign currency, the Fund may enter 
into a forward contract to purchase an amount of currency equal to some or 
all of the value of the anticipated purchase, for a fixed amount of U.S. 
dollars or other currency. The Fund may, however, close out the forward 
contract prior to purchasing the security which was the subject of the 
anticipatory hedge. 

   Lastly, the Fund is permitted to enter into forward contracts with respect 
to currencies in which certain of its portfolio securities are denominated 
and on which options have been written (see "Options and Futures 
transactions"). 

   In all of the above circumstances, if the currency in which the Fund's 
portfolio securities (or anticipated portfolio securities) are denominated 
rises in value with respect to the currency which is being purchased (or 
sold), then the Fund will have realized fewer gains than had the Fund not 
entered into the forward contracts. Moreover, the precise matching of the 
forward contract amounts and the value of the securities involved will not 
generally be possible, since the future value of such securities in foreign 
currencies will change as a consequence of market movements in the value of 
those securities between the date the forward contract is entered into and 
the date it matures. The successful use of the foregoing investment practices 
draws upon the Investment Manager's special skills and experience with 
respect to such instruments and usually depends upon the Investment Manager's 
ability to forecast currency exchange rate movements correctly. Should 
exchange rates move in an unexpected manner, the Fund may not achieve the 
anticipated benefits of forward contracts or may realize losses and thus be 
in a worse position than if such strategies had not been used. Unlike many 
exchange-traded futures contracts and options on futures contracts, there are 
no daily price fluctuation limits with respect to options on currencies and 
forward contracts, and adverse market movements could therefore continue to 
an unlimited extent over a period of time. In addition, the correlation 
between movements in the prices of such instruments and movements in the 
price of currencies hedged or used for cover will not be perfect and could 
produce unanticipated losses. 

   The Fund is not required to enter into such transactions with regard to 
its foreign currency-denominated securities and will not do so unless deemed 
appropriate by the Investment Manager. The Fund generally will not enter into 
a forward contract with a term of greater than one year, although it may 
enter into forward contracts for periods of up to five years. The Fund may be 
limited in its ability to enter into hedging transactions involving forward 
contracts by the Internal Revenue Code requirements relating to 
qualifications as a regulated investment company (see "Dividends, 
Distributions and Taxes"). 

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

PORTFOLIO MANAGEMENT 

The Fund's portfolio is actively managed by its Investment Manager with a 
view to achieving the Fund's investment objectives. 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 
the rating of the security, research, analysis and appraisals of brokers and 
dealers, including Dean Witter Reynolds Inc. ("DWR"), and other broker-dealer 
affiliates of InterCapital and others regarding economic developments and 
interest rate trends, and the Investment Manager's own analysis of factors 
they deem relevant. The Fund is managed within InterCapital's Taxable Income 
Group, which manages 24 funds and fund portfolios, with approximately $13 
billion in assets at June 30, 1997. Peter M. Avelar, Rajesh K. Gupta and Vinh 
Q. Tran have been the primary portfolio managers of the Fund since its 
inception. Peter M. Avelar, Senior Vice President of InterCapital, has been 
managing portfolios comprised of high yield fixed-income securities at 
InterCapital for over five years. Rajesh K. Gupta, Senior Vice President of 
InterCapital, has been managing portfolios comprised of government securities 
at InterCapital for over five years. Vinh Q. Tran, Vice President of 
InterCapital, has been managing portfolios comprised of worldwide 
fixed-income securities at InterCapital for over five years. 

   Securities purchased by the Fund are generally sold by dealers acting as 
principal for their own accounts. Brokerage commissions are not normally 
charged but such transactions generally involve costs in the form of spreads 
between bid and asked prices. Orders for transactions in other portfolio 
securities and commodities 

                                                                             17

<PAGE>

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

   The Fund may sell portfolio securities without regard to the length of 
time that they have been held, in order to take advantage of new investment 
opportunities or yield differentials, or because the Fund desires to preserve 
gains or limit losses due to changing economic conditions, interest rate 
trends, or the financial condition of the issuer. 

   The expenses of the Fund relating to its portfolio management are likely 
to be greater than those incurred by other investment companies investing 
primarily in securities issued by domestic issuers such as custodial costs, 
brokerage commissions and other transaction charges related to investing on 
foreign markets are generally higher than in the United States. Short-term 
gains and losses may result from the aforementioned portfolio transactions. 
See "Dividends, Distributions and Taxes" for a discussion of the tax 
implications of the Fund's trading policy. 

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

   The investment restrictions listed below are among the restrictions which 
have been adopted by the Fund as fundamental policies. Under the Act, a 
fundamental policy may not be changed without the vote of a majority of the 
outstanding voting securities of the Fund, as defined in the Act. For 
purposes of the following limitations (with the exception of Restriction 4): 
(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 more than 5% of its total assets in the securities of any one
   issuer (other than obligations of, or guaranteed by, the United States
   Government, its agencies or instrumentalities).

      2. Invest more than 5% of the value of its total assets in securities of
   issuers having a record, together with predecessors, of less than three
   years of continuous operation. This restriction shall not apply to
   Mortgage-Backed and Asset-Backed Securities or to any obligation issued or
   guaranteed by the United States Government, its agencies or
   instrumentalities.

      3. Invest 25% or more of the value of its total assets in securities of
   issuers in any one industry, except that the Fund will invest at least 25%
   of its total assets in Mortgage-Backed Securities under normal market
   conditions. For the purpose of this restriction, gas, electric, water and
   telephone utilities will be treated as being a separate industry. This
   restriction does not apply to obligations issued or guaranteed by the United
   States Government or its agencies or instrumentalities.

      4. Borrow money in excess of 33 1/3% of the Fund's total assets
   (including the proceeds of the borrowings).

      5. Purchase more than 10% of the voting securities, or more than 10% of
   any class of securities, of any issuer. For purposes of this restriction,
   all outstanding debt securities of an issuer are considered as one class and
   all preferred stocks of an issuer are considered as one class.

   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 Dean Witter
Distributors Inc. (the "Distributor"), an affiliate of the Investment Manager,
shares of the Fund are distributed by the Distributor and offered by DWR and
other dealers who have entered into selected dealer agreements with the
Distributor ("Selected Broker-Dealers"). The principal executive office of the
Distributor is located at Two World Trade Center, New York, New York 10048.

   The Fund offers four classes of shares (each, a "Class"). Class A shares 
are sold to investors with an 

18

<PAGE>

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

   The minimum initial purchase is $1,000 for each Class of shares, although 
Class D shares are only available to persons investing $5 million or more and 
to certain other limited categories of investors. For the purpose of meeting 
the minimum $5 million initial investment for Class D shares, and subject to 
the $1,000 minimum initial investment for each Class of the Fund, an 
investor's existing holdings of Class A shares of the Fund and other Dean 
Witter Funds that are multiple class funds ("Dean Witter Multi-Class Funds") 
and shares of Dean Witter Funds sold with a front-end sales charge ("FSC 
Funds") and concurrent investments in Class D shares of the Fund and other 
Dean Witter Multi-Class Funds will be aggregated. Subsequent purchases of 
$100 or more may be made by sending a check, payable to Dean Witter 
Diversified Income Trust, directly to Dean Witter Trust Company (the 
"Transfer Agent") at P.O. Box 1040, Jersey City, NJ 07303 or by contacting an 
account executive of DWR or other Selected-Broker Dealer. When purchasing 
shares of the Fund, investors must specify whether the purchase is for Class 
A, Class B, Class C or Class D shares. If no Class is specified, the Transfer 
Agent will not process the transaction until the proper Class is identified. 
The minimum initial purchase in the case of investments through EasyInvest, 
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. In the case of 
investments pursuant to Systematic Payroll Deduction Plans (including 
Individual Retirement Plans), the Fund, in its discretion, may accept 
investments without regard to any minimum amounts which would otherwise be 
required if the Fund has reason to believe that additional investments will 
increase the investment in all accounts under such Plans to at least $1,000. 
Certificates for shares purchased will not be issued unless a request is made 
by the shareholder in writing to the Transfer Agent. 

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

ALTERNATIVE PURCHASE ARRANGEMENTS 

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

   Each Class A, Class B, Class C or Class D share of the Fund represents an 
identical interest in the investment portfolio of the Fund except that Class 
A, Class B and Class C shares bear the expenses of the ongoing shareholder 
service fees, Class B and Class C shares bear the expenses of the ongoing 
distribution fees and Class A, Class B and Class C shares which are redeemed 
subject to a CDSC bear the expense of the additional incremental distribution 
costs resulting from the CDSC 

                                                                             19

<PAGE>

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

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

CLASS A SHARES. Class A shares are sold at net asset value plus an initial 
sales charge of up to 4.25%. The initial sales charge is reduced for certain 
purchases. Investments of $1 million or more (and investments by certain 
other limited categories of investors) are not subject to any sales charges 
at the time of purchase but are subject to a CDSC of 1.0% on redemptions made 
within one year after purchase, except for certain specific circumstances. 
Class A shares are also subject to a 12b-1 fee of up to 0.25% of the average 
daily net assets of the Class. See "Initial Sales Charge Alternative--Class A 
Shares." 

CLASS B SHARES. Class B shares are offered at net asset value with no initial 
sales charge but are subject to a CDSC (scaled down from 5.0% to 1.0%) if 
redeemed within six years of purchase. (Class B shares purchased by certain 
qualified employer-sponsored benefit plans are subject to a CDSC scaled down 
from 2.0% to 1.0% if redeemed within three years after purchase.) This CDSC 
may be waived for certain redemptions. Class B shares are also subject to an 
annual 12b-1 fee of 0.85% 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 0.85% of the average daily net 
assets of the Class C shares. The Class C shares' distribution fee may cause 
that Class to have higher expenses and pay lower dividends than Class A or 
Class D shares. See "Level Load Alternative--Class C Shares." 

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

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

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

   Finally, investors should consider the effect of the CDSC period and any 
conversion rights of the Classes in the context of their own investment time 
frame. For example, although Class C shares are subject to a significantly 
lower CDSC upon redemptions, they do not, unlike Class B shares, convert into 
Class A shares after approximately ten years, and, therefore, are subject to 
an ongoing 12b-1 fee of 0.85% (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 

20

<PAGE>

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

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

   Sales personnel may receive different compensation for selling each Class 
of shares. Investors should understand that the purpose of a CDSC is the same 
as that of the initial sales charge in that the sales charges applicable to 
each Class provide for the financing of the distribution of shares of that 
Class. 

   Set forth below is a chart comparing the sales charge, 12b-1 fees and 
conversion options applicable to each Class of shares:

for each Class of shares and "Determination of Net Asset Value," "Dividends, 
Distributions and Taxes" and "Shareholder Services--Exchange Privilege" for 
other differences between the Classes of shares. 

INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES 

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

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

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

   The above schedule of sales charges is applicable to purchases in a single 
transaction by, among others: (a) an individual; (b) an individual, his or 
her spouse and their children under the age of 21 purchasing shares for his, 
her or their own accounts; (c) a trustee or other fiduciary purchasing shares 
for a single trust estate or a single fiduciary account; (d) a pension, 
profit-sharing or other employee benefit plan qualified or non-qualified 
under Section 401 of the Internal Revenue Code; (e) tax-exempt organizations 
enumerated in Section 501(c)(3) or (13) of the Internal Revenue Code; (f) 
employee benefit plans qualified under Section 401 of the Internal Revenue 
Code 

                                                                             21

of a single employer or of employers who are "affiliated persons" of each 
other within the meaning of Section 2(a)(3)(c) of the Act; and for 
investments in Individual Retirement Accounts of employees of a single 
employer through Systematic Payroll Deduction plans; or (g) any other 
organized group of persons, whether incorporated or not, provided the 
organization has been in existence for at least six months and has some 
purpose other than the purchase of redeemable securities of a registered 
investment company at a discount. 

COMBINED PURCHASE PRIVILEGE. Investors may have the benefit of reduced sales 
charges in accordance with the above schedule by combining purchases of Class 
A shares of the Fund in single transactions with the purchase of Class A 
shares of other Dean Witter Multi-Class Funds and shares of FSC Funds. The 
sales charge payable on the purchase of the Class A shares of the Fund, the 
Class A shares of other Dean Witter Multi-Class Funds and the shares of the 
FSC Funds will be at their respective rates applicable to the total amount of 
the combined concurrent purchases of such shares. 

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

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

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

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

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

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

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

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

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

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

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

DWR or another Selected Broker-Dealer or consult the Statement of Additional 
Information. 

CONTINGENT DEFERRED SALES 
CHARGE ALTERNATIVE--CLASS B SHARES 

Class B shares are sold at net asset value next determined without an initial 
sales charge so that the full amount of an investor's purchase payment may be 
immediately invested in the Fund. A CDSC, however, will be imposed on most 
Class B shares redeemed within six years after purchase. The CDSC will be 
imposed on any redemption of shares if after such redemption the aggregate 
current value of a Class B account with the Fund falls below the aggregate 
amount of the investor's purchase payments for Class B shares made during the 
six years (or, in the case of shares held by certain employer-sponsored 
benefit plans, three years) preceding the redemption. In addition, Class B 
shares are subject to an annual 12b-1 fee of 0.85% of the lesser of: (a) the 
average daily aggregate gross sales of the Fund's Class B shares since the 
inception of the Fund (not including reinvestments of dividends or capital 
gains distributions), less the average daily aggregate net asset value of the 
Fund's Class B shares redeemed since the Fund's inception upon which a CDSC 
has been imposed or waived, or (b) the average daily net assets of Class B. 

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

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

CDSC WAIVERS. A CDSC will not be imposed on: (i) any amount which represents 
an increase in value of shares purchased within the six years (or, in the 
case of shares held by certain employer-sponsored benefit plans, three years) 
preceding the redemption; (ii) the current net asset value of shares 
purchased more than six years (or, in the case of shares held by certain 
employer-sponsored benefit plans, three years) prior to the redemption; and 
(iii) the current net asset value of shares purchased through reinvestment of 
dividends or distributions and/or shares acquired in exchange for shares of 
FSC Funds or of other Dean Witter Funds acquired in exchange for such shares. 
Moreover, in determining whether a CDSC is applicable it will be assumed that 
amounts described in (i), (ii) and (iii) above (in that order) are redeemed 
first. 

   In addition, the CDSC, if otherwise applicable, will be waived in the case 
of: 
<PAGE>
   (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 

                                                                             23

<PAGE>

retirement plan following retirement (or, in the case of a "key employee" of 
a "top heavy" plan, following attainment of age 59 1/2);   (B) distributions 
from an IRA or 403(b) Custodial Account following attainment of age 59 1/2; 
or   (C) a tax-free return of an excess contribution to an IRA; and 

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

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

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

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

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

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

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 

24

<PAGE>

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 0.85% of the average daily net assets of the Class. Unlike Class B 
shares, Class C shares have no conversion feature and, accordingly, an 
investor that purchases Class C shares will be subject to 12b-1 fees 
applicable to Class C shares for an indefinite period subject to annual 
approval by the Fund's Board of Trustees and regulatory limitations. 

NO LOAD ALTERNATIVE--CLASS D SHARES 

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

PLAN OF DISTRIBUTION 

The Fund has adopted a Plan of Distribution pursuant to Rule 12b-1 under the 
Act with respect to the distribution of Class A, Class B and Class C shares 
of the Fund. In the case of Class A and Class C shares, the Plan provides 
that the Fund will reimburse the Distributor and others for the expenses of 
certain activities and services incurred by them specifically on behalf of 
those shares. Reimbursements for these expenses will be made in monthly 
payments by the Fund to the Distributor, which will in no event exceed 
amounts equal to payments at the annual rates of 0.25% and 0.85% 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 0.85% 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 0.20% and 0.25% of the average 
daily net assets of each of these Classes, respectively, is currently 
characterized as a service fee. A service fee is a payment made for personal 
service and/or the maintenance of shareholder accounts. 

   Additional amounts paid under the Plan in the case of Class B and Class C 
shares are paid to the Distributor for services provided and the expenses 
borne by the Distributor and others in the distribution of the shares of 
those Classes, including the payment of commissions for sales of the shares 
of those Classes and incentive compensation to and expenses of DWR's account 
executives and others who engage in or support distribution of shares or who 
service shareholder accounts, including overhead and telephone expenses; 
printing and distribution of prospectuses and reports used in connection with 
the offering of the Fund's shares to other than current shareholders; and 
preparation, printing and distribution of sales literature and advertising 
materials. In addition, the Distributor may utilize fees paid pursuant to the 
Plan in the case of Class B shares to compensate DWR and other Selected 
Broker-Dealers for their opportunity costs in advancing such amounts, which 
compensation would be in the form of a carrying charge on any unreimbursed 
expenses. 

   For the fiscal year ended October 31, 1996, Class B shares of the Fund 
accrued payments under the Plan amounting to $5,383,849, which amount is 
equal to 0.85% of the Fund's average daily net assets for the fiscal year. 

                                                                             25

<PAGE>

The payments accrued under the Plan were calculated pursuant to clause (b) of 
the compensation formula under the Plan. All shares held prior to July 28, 
1997 have been designated Class B shares. 

   In the case of Class B shares, at any given time, the expenses 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 $12,284,935 at October 31, 1996, which was equal to 1.65% of the net 
assets of the Fund 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 0.85% of the average 
daily net assets of Class A or Class C, respectively, will not be reimbursed 
by the Fund through payments in any subsequent year, except that expenses 
representing a gross sales commission credited to account executives at the 
time of sale may be reimbursed in the subsequent calendar year. No interest 
or other financing charges will be incurred on any Class A or Class C 
distribution expenses incurred by the Distributor under the Plan or on any 
unreimbursed expenses due to the Distributor pursuant to the Plan. 

DETERMINATION OF NET ASSET VALUE 

The net asset value per share is determined by taking the net assets of the 
Fund, dividing by the number of shares outstanding and adjusting the result 
to the nearest cent. The assets belonging to the Class A, Class B, Class C 
and Class D shares will be invested together in a single portfolio. The net 
asset value of each Class, however, will be determined separately by 
subtracting each Class's accrued expenses and liabilities. The net asset 
value per share is determined by the Investment Manager as of 4:00 P.M. New 
York time (or, on days when the New York Stock Exchange closes prior to 4:00 
P.M., at such earlier time) on each day that the New York Stock Exchange is 
open. The 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 
securities are traded on more than one exchange, the securities are valued on 
the exchange designated as the primary market pursuant to procedures adopted 
by the Trustees); and (2) all other portfolio securities for which 
over-the-counter market quotations are readily available are valued at the 
latest bid price. When market quotations are not readily available, including 
circumstances under which it is determined by the Investment Manager that 
sale 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. For valuation purposes, quotations of foreign portfolio securities, 
other assets and liabilities and forward contracts stated in foreign currency 
are translated into U.S. dollar equivalents at the prevailing market rates 
prior to the close of the New York Stock Exchange. 

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

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

   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 regular close 
of the New York Stock Exchange. The values of such securities 

26

<PAGE>

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 regular close of the New York Stock Exchange. Occasionally, 
events which 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 materially affecting the value of such 
securities occur during such period, then these securities will be valued at 
their fair value as determined in good faith under procedures established by 
and under the supervision of the 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 Dean Witter Fund), unless the
shareholder requests that they be paid in cash. Shares so acquired are acquired
at net asset value and are not subject to the imposition of a front-end sales
charge or a CDSC (see "Redemptions and Repurchases").

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

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

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

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

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

   For further information regarding plan administration, custodial fees and 
other details, investors should contact their account executive or the 
Transfer Agent. 

EXCHANGE PRIVILEGE 

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

                                                                             27

<PAGE>

Municipal Trust, which are Dean Witter Funds offered with a CDSC ("CDSC 
Funds"). Exchanges may be made after the shares of the Fund acquired by 
purchase (not by exchange or dividend reinvestment) have been held for thirty 
days. There is no waiting period for exchanges of shares acquired by exchange 
or dividend reinvestment. 

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

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

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

   The current prospectus for each fund describes its investment objective(s) 
and policies, and shareholders should obtain a copy and examine it carefully 
before investing. Exchanges are subject to the minimum investment requirement 
of each Class of shares and any other conditions imposed by each fund. In the 
case of a Shareholder holding a share certificate or certificates, no 
exchanges may be made until all applicable share certificates have been 
received by the Transfer Agent and deposited in the Shareholder's account. An 
exchange will be treated for federal income tax purposes the same as a 
repurchase or redemption of shares, on which the shareholder may realize a 
capital gain or loss. However, the ability to deduct capital losses on an 
exchange may be limited in situations where there is an exchange of shares 
wihin 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 other Selected Broker-Dealer is the current dealer of record and 
its account numbers are part of the account information, shareholders may 
initiate an exchange of shares of the Fund for shares of any of the Dean 
Witter Funds (for which the Exchange Privilege is 

28

<PAGE>

available) pursuant to this Exchange Privilege by contacting their account 
executive (no Exchange Privilege Authorization Form is required). Other 
shareholders (and those shareholders who are clients of DWR or another 
Selected Broker-Dealer but who wish to make exchanges directly by writing or 
telephoning the Transfer Agent) must complete and forward to the Transfer 
Agent an Exchange Privilege Authorization Form, copies of which may be 
obtained from the Transfer Agent, to initiate an exchange. If the 
Authorization Form is used, exchanges may be made in writing or by contacting 
the Transfer Agent at (800) 869-NEWS (toll free). The Fund will employ 
reasonable procedures to confirm that exchange instructions communicated over 
the telephone are genuine. Such procedures may include requiring various 
forms of personal identification such as name, mailing address, social 
security or other tax identification number and DWR or other Selected 
Broker-Dealer account number (if any). Telephone instructions may also be 
recorded. If such procedures are not employed, the Fund may be liable for any 
losses due to unauthorized or fraudulent instructions. Telephone exchange 
instructions will be accepted if received by the Transfer Agent between 9:00 
and 4:00 p.m., New York time, on any day the New York Stock Exchange is open. 
Any shareholder wishing to make an exchange who has previously filed an 
Exchange Privilege Authorization Form and who is unable to reach the Fund by 
telephone should contact his or her DWR or other Selected Broker-Dealer 
account executive, if appropriate, or make a written exchange request. 
Shareholders are advised that during periods of drastic economic or market 
changes it is possible that the telephone exchange procedures may be 
difficult to implement, although this has not been the experience of the Dean 
Witter Funds in the past. 

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

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

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

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

   The CDSC, if any, will be the only fee imposed by the Fund or the 
Distributor. The 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. If the shares to be redeemed have 
recently been purchased by check, payment of the redemption proceeds may be 
delayed for the minimum time needed to verify that the check used for 
investment has been honored (not more than fifteen days from the time of 
receipt of the check by the Transfer Agent). Shareholders maintaining margin 
accounts with DWR or another Selected Broker-Dealer are referred to their 
account executive regarding restrictions on redemption of shares of the Fund 
pledged in the margin account. 

REINSTATEMENT PRIVILEGE. A shareholder who has had his or her shares 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, on sixty days' notice, 
to redeem at their net asset value 

                                                                             29

<PAGE>

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 
EasyInvest(Service Mark), if after twelve months the shareholder has 
invested less than $1,000 in the account. However, before the Fund redeems 
such shares and sends the proceeds to the shareholder, it will notify the 
shareholder that the value of the shares is less than the applicable amount 
and allow the shareholder sixty days to make an additional investment in an 
amount which will increase the value of 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 declare and pay monthly income dividends and to
distribute net realized short-term and net long-term capital gains, if any, at
least once each year. The Fund may, however, determine either to distribute or
to retain all or a portion of any long-term capital gains in any year for
reinvestment.

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

TAXES. Because the Fund intends to distribute all of its net investment 
income and net capital gains to 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 on such income and capital gains. 

   Gains or losses on the Fund's transactions in certain listed options on 
and futures and options on futures traded on U.S. exchanges generally are 
treated as 60% long-term gain or loss and 40% short-term gain or loss. When 
the Fund engages in options and futures transactions, various tax regulations 
applicable to the Fund may have the effect of causing the Fund to recognize a 
gain or loss for tax purposes before that gain or loss is realized, or to 
defer recognition of a realized loss for tax purposes. Recognition, for tax 
purposes, of an unrealized loss may result in a lesser amount of the Fund's 
realized net gains being available for distribution. 

   Shareholders who are required to pay taxes on their income will normally 
have to pay federal income taxes, and any applicable state and/or 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 and net 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. 

   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. Since the Fund's income is expected 
to be derived primarily from interest rather than dividends, only a small 
portion, if any, of the Fund's dividends and distributions is expected to be 
eligible for the dividends received deduction to corporation shareholders. 

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

   After the end of the calendar year, shareholders will receive full 
information on their dividends and capital gains distributions for tax 
purposes. 

   To avoid being subject to a 31% federal backup withholding tax on taxable 
dividends, capital gains distributions and the proceeds of redemptions and 
repurchases, shareholders' taxpayer identification numbers must be furnished 
and certified as to their accuracy. Shareholders who are not citizens or 
residents of, or entities organized in, the United States may be subject to 
withholding taxes of up to 30% on certain payments received from the Fund.

<PAGE>

   Dividends, interest and gains received by the Fund may give rise to 
withholding and other taxes imposed by foreign countries. If it qualifies for 
and has made the appropriate election with the Internal Revenue Service, the 
Fund will report annually to its shareholders the amount per share of such 
taxes, to enable shareholders to claim United States foreign tax credits or 
deductions with respect to such taxes. In the absence of such an election, 
the Fund would deduct foreign tax in computing the amount of its 
distributable income. 

   The foregoing discussion relates solely to the federal income tax 
consequences of an investment in the Fund. Distributions may also be subject 
to state and local taxes; therefore, each shareholder is advised to consult 
his or her own tax adviser. 

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
maximum offering price 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 Fund's yield
for each Class.

   The "average annual total return" of the Fund refers to a figure 
reflecting the average annualized percentage increase (or decrease) in the 
value of an initial investment in a Class of the Fund of $1,000 over periods 
of one, five and ten years, or over the life of the Fund if less than any of 
the foregoing. Average annual total return reflects all income earned by the 
Fund, any appreciation or depreciation of the Fund's assets, all expenses 
incurred by the applicable Class, and all sales charges which 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, and 
year-by-year or other types of total return figures. Such calculations may or 
may not reflect the deduction of any sales charge which, if reflected, would 
reduce the performance quoted. The Fund may also advertise the growth of 
hypothetical investments of $10,000, $50,000 and $100,000 in each Class of 
shares of the Fund. The Fund from time to time may also advertise its 
performance relative to certain performance rankings and indexes compiled by 
independent organizations (such as mutual fund performance rankings of Lipper 
Analytical Services, Inc.). 

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

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

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

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

                                                                             31

Massachusetts counsel to the Fund, the risk to Fund shareholders of personal 
liability is remote. 

CODE OF ETHICS. Directors, officers and employees of InterCapital, Dean 
Witter Services Company Inc. and the Distributor are subject to a strict Code 
of Ethics adopted by those companies. The Code of Ethics is intended to 
ensure that the interests of shareholders and other clients are placed ahead 
of any personal interest, that no undue personal benefit is obtained from a 
person's employment activities and that actual and potential conflicts of 
interest are avoided. To achieve these goals and comply with regulatory 
requirements, the Code of Ethics requires, among other things, that personal 
securities transactions by employees of the companiesbe subject to an advance 
clearance process to monitor that no Dean Witter Fund is engaged at the same 
time in a purchase or sale of the same security. The Code of Ethics bans the 
purchase of securities in an initial public offering, and also prohibits 
engaging in futures and options transactions and profiting on short-term 
trading (that is, a purchase within sixty days of a sale or a sale within 
sixty days of a purchase) of a security. In addition, investment personnel 
may not purchase or sell a security for their personal account within thirty 
days before or after any transaction in any Dean Witter Fund managed by them. 
Any violations of the Code of Ethics are subject to sanctions, including 
reprimand, demotion or suspension or termination of employment. The Code of 
Ethics comports with regulatory requirements and the recommendations in the 
1994 report by the Investment Company Institute Advisory Group on Personal 
Investing. 

MASTER/FEEDER CONVERSION. The Fund reserves the right to seek to achieve its 
investment 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 cover of 
this Prospectus.

APPENDIX--RATINGS OF INVESTMENTS 
- -------------------------------------------------------------------------------

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

                                 BOND RATINGS 

Aaa      Bonds 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       Bonds 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 bonds. They are rated lower than the
         best bonds 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        Bonds 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      Bonds 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
         bonds lack outstanding investment characteristics and in fact have
         speculative characteristics as well.

         Bonds rated Aaa, Aa, A and Baa are considered investment grade bonds. 

Ba       Bonds 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 over
         the future. Uncertainty of position characterizes bonds in this class.

B        Bonds which are rated B generally lack characteristics of desirable
         investments. 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      Bonds 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       Bonds 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        Bonds which are rated C are the lowest rated class of bonds, and
         issues so rated can be regarded as having extremely poor prospects of
         ever attaining any real investment standing.

   CONDITIONAL RATING: Municipal bonds for which the security depends upon 
the completion of some act or the fulfillment of some condition are rated 
conditionally. These are bonds secured by (a) earnings of projects under 
construction, (b) earnings of projects unseasoned in operation experience, 
(c) rentals which begin when facilities are completed, or (d) payments to 
which some other limiting condition attaches. Parenthetical rating denotes 
probable credit stature upon completion of construction or elimination of 
basis of condition. 

   RATING REFINEMENTS: Moody's may apply numerical modifiers, 1, 2 and 3 in 
each generic rating classification from Aa through B in its corporate and 
municipal bond 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. 

                                                                             33

                           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. 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") 

                                 BOND RATINGS 

   A Standard & Poor's bond 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. 

AAA      Debt rated AAA has the highest rating assigned by Standard & Poor's.
         Capacity to pay interest and repay principal is extremely strong.

AA       Debt rated AA has a very strong capacity to pay interest and repay
         principal and differs from the highest-rated issues only in small
         degree.

A        Debt rated A has 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 debt in
         higher-rated categories.

BBB      Debt rated BBB is 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 debt in this category than for debt
         in higher-rated categories.

         Bonds rated AAA, AA, A and BBB are considered investment grade bonds. 

BB       Debt rated BB has less near-term vulnerability to default than other
         speculative grade debt. However, it faces major ongoing uncertainties
         or exposure to adverse business, financial or economic conditions
         which could lead to inadequate capacity to meet timely interest and
         principal payment.

B        Debt rated B has a greater vulnerability to default but presently has
         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      Debt rated CCC has a current identifiable vulnerability to default,
         and is 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, it is not likely to have the capacity to pay interest and
         repay principal.

CC       The rating CC is typically applied to debt subordinated to senior debt
         which is assigned an actual or implied CCC rating.

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

34

<PAGE>

CI       The rating CI is reserved for income bonds 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.

         Bonds 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 debt 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 ratings 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.

         In the case of municipal bonds, the foregoing ratings are sometimes
         followed by a "p" which indicates that the rating is provisional. A
         provisional rating assumes the successful completion of the project
         being financed by the bonds being rated and indicates that payment of
         debt service requirements is largely or entirely dependent upon the
         successful and timely completion of the project. This rating, however,
         while addressing credit quality subsequent to completion of the
         project, makes no comment on the likelihood or risk of default upon
         failure of such completion.

                           COMMERCIAL PAPER RATINGS 

   Standard and 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 S&P 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 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. 

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.

                                                                             35
