INCOME BUILDER FUND 
PROSPECTUS -- NOVEMBER 26, 1997 
- ------------------------------------------------------------------------------ 

DEAN WITTER INCOME BUILDER FUND (THE "FUND") IS AN OPEN-END, DIVERSIFIED 
MANAGEMENT INVESTMENT COMPANY WHOSE PRIMARY INVESTMENT OBJECTIVE IS TO SEEK 
REASONABLE INCOME. GROWTH OF CAPITAL IS THE SECONDARY OBJECTIVE. THE FUND 
SEEKS TO ACHIEVE ITS OBJECTIVES BY INVESTING, UNDER NORMAL MARKET CONDITIONS, 
AT LEAST 65% OF ITS TOTAL ASSETS IN A DIVERSIFIED PORTFOLIO OF 
INCOME-PRODUCING EQUITY SECURITIES, INCLUDING COMMON STOCK, PREFERRED STOCK 
AND CONVERTIBLE SECURITIES. UP TO 35% OF THE FUND'S ASSETS MAY BE INVESTED IN 
FIXED-INCOME SECURITIES OR COMMON STOCKS THAT DO NOT PAY A REGULAR DIVIDEND 
BUT ARE EXPECTED TO CONTRIBUTE TO THE FUND'S ABILITY TO MEET ITS INVESTMENT 
OBJECTIVES. 

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

                     management, advisory, management and administrative
                     capacities to 100 investment companies and other
                     portfolios with net assets under management of
                     approximately $100.7 billion at October 31, 1997.
- ------------------------------------------------------------------------------
MANAGEMENT           The Investment Manager receives a monthly fee at the
FEE                  annual rate of 0.75% of the Fund's average daily net
                     assets (see page 8).
- ------------------------------------------------------------------------------
DISTRIBUTOR AND      Dean Witter Distributors Inc. (the "Distributor"). The
DISTRIBUTION         Fund has adopted a distribution plan pursuant to Rule
FEE                  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 0.25% of the average daily net assets of
                     the Class are currently each characterized as a service
                     fee within the meaning of the National Association of
                     Securities Dealers, Inc. guidelines. The remaining
                     portion of the 12b-1 fee, if any, is characterized as an
                     asset-based sales charge (see pages 15 and 21).
- ------------------------------------------------------------------------------
ALTERNATIVE          Four classes of shares are offered: 
PURCHASE
ARRANGEMENTS         o Class A shares are offered with a front-end sales
                     charge, starting at 5.25% and reduced for larger
                     purchases. Investments of $1 million or more (and
                     investments by certain other limited categories of
                     investors) are not subject to any sales charge at the
                     time of purchase but a contingent deferred sales charge
                     ("CDSC") of 1.0% may be imposed on redemptions within one
                     year of purchase. The Fund is authorized to reimburse the
                     Distributor for specific expenses incurred in promoting
                     the distribution of the Fund's Class A shares and
                     servicing shareholder accounts pursuant to the Fund's
                     12b-1 Plan. Reimbursement may in no event exceed an
                     amount equal to payments at an annual rate of 0.25% of
                     average daily net assets of the Class (see pages 15, 17
                     and 21).

                     o Class B shares are offered without a front-end sales
                     charge, but will in most cases be subject to a CDSC
                     (scaled down from 5.0% to 1.0%) if redeemed within six
                     years after purchase. The CDSC will be imposed on any
                     redemption of shares if after such redemption the
                     aggregate current value of a Class B account with the
                     Fund falls below the aggregate amount of the investor's
                     purchase payments made during the six years preceding the
                     redemption. A different CDSC schedule applies to
                     investments by certain qualified plans. Class B shares
                     are also subject to a 12b-1 fee assessed at the annual
                     rate of 1.0% of the lesser of: (a) the average daily net
                     sales of the Fund's Class B shares or (b) the average
                     daily net assets of Class B. All shares of the Fund held
                     prior to July 28, 1997 have been designated Class B
                     shares. Shares held before May 1, 1997 that have been
                     designated Class B shares will convert to Class A shares
                     in May, 2007. In all other instances, Class B shares
                     convert to Class A shares approximately ten years after
                     the date of the original purchase (see pages 15, 19 and
                     20).

                     o Class C shares are offered without a front-end sales
                     charge, but will in most cases be subject to a CDSC of
                     1.0% if redeemed within one year after purchase. The Fund
                     is authorized to reimburse the Distributor for specific
                     expenses incurred in promoting the distribution of the
                     Fund's Class C shares and servicing shareholder accounts
                     pursuant to the Fund's 12b-1 Plan. Reimbursement may in
                     no event exceed an amount equal to payments at an annual
                     rate of 1.0% of average daily net assets of the Class
                     (see pages 15 and 21).

                     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 fees (see pages 15 and 21).
- ------------------------------------------------------------------------------
DIVIDENDS AND        The Fund pays quarterly income dividends and distributes
CAPITAL GAINS        substantially all of any net short-term and net long-term
DISTRIBUTIONS        capital gains at least once each year. The Fund may,
                     however, determine to retain all or part of any net
                     long-term capital gains in any year for reinvestment.
                     Dividends and capital gains distributions paid on shares
                     of a Class are automatically reinvested in additional
                     shares of the same Class at net asset value unless the
                     shareholder elects to receive cash. Shares acquired by
                     dividend and distribution reinvestment will not be
                     subject to any sales charge or CDSC (see pages 23 and
                     26).
- ------------------------------------------------------------------------------
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 25).
- ------------------------------------------------------------------------------
RISK                 The net asset value of the Fund's shares will fluctuate
CONSIDERATIONS       with changes in market value of portfolio securities.
                     Dividends payable by the Fund will vary in relation to
                     the amounts of dividends earned on common stock and
                     interest earned on fixed-income securities. The value of
                     the Fund's convertible and fixed-income portfolio
                     securities and, therefore, the Fund's net asset value per
                     share, may increase or decrease due to various factors,
                     including changes in prevailing interest rates.
                     Generally, a rise in interest rates will result in a
                     decrease in the Fund's net asset value per share, while a
                     drop in interest rates will result in an increase in the
                     Fund's net asset value per share. The high yield, high
                     risk fixed-income securities in which the Fund may invest
                     are subject to greater risk of loss of income and
                     principal than higher rated, lower yielding fixed-income
                     securities. The prices of high yield, high risk
                     securities have been found to be less sensitive to
                     changes in prevailing interest rates than higher rated
                     investments, but are likely to be more sensitive to
                     adverse economic changes or individual corporate
                     developments. The Fund may enter into repurchase
                     agreements, may purchase foreign securities; securities
                     on a when-issued and delayed delivery basis and may
                     utilize certain investement techniques, all of which
                     involve certain special risks (see pages 11-14).

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

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

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

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

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

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

(7)    There were no outstanding shares of Class A, Class C or Class D prior 
       to July 28, 1997. Accordingly, "Total Fund Operating Expenses," as 
       shown above with respect to those Classes, are estimates based upon the 
       sum of 12b-1 Fees, Management Fees and estimated "Other Expenses."

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

Dean Witter Income Builder Fund (the "Fund") is an open-end, diversified 
management investment company. The Fund is a trust of the type commonly known 
as a "Massachusetts business trust" and was organized under the laws of The 
Commonwealth of Massachusetts on March 21, 1996. 

   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 assets of approximately 
$97 billion at October 31, 1997. The Investment Manager also manages 
portfolios of pension plans, other institutions and individuals which 
aggregated approximately $3.7 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 incurred by the Investment Manager, the Fund 
pays the Investment Manager monthly compensation calculated daily by applying 
the annual rate of 0.75% to the Fund's net assets. For the fiscal year ended 
September 30, 1997, the Fund accrued total compensation to the Investment 
Manager amounting to 0.75% of the Fund's average daily net assets and the 
total expenses of Class B amounted to 1.85% of the average daily net assets 
of Class B. Shares of Class A, Class C and Class D were first issued on July 
28, 1997. 

   The expenses of the Fund include: the fee of the Investment Manager; the 
fee pursuant to the Plan of Distribution (see "Purchase of Fund Shares"); 
taxes; transfer agent, custodian, auditing fees; certain legal fees; and 
printing and other expenses relating to the Fund's operations which are not 
expressly assumed by the Investment Manager under its Investment Management 
Agreement with the Fund. 

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

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

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

COMMON STOCKS, PREFERRED STOCKS AND SECURITIES CONVERTIBLE INTO COMMON 
STOCKS. The Fund will invest, under normal market conditions, primarily in 
common stocks of large-cap companies which have a record of paying dividends 
and, in the opinion of the Investment Manager, have the potential for 
maintaining dividends, in preferred stock and in securities convertible into 
common stocks of small and mid-cap companies. The Investment Manager intends 
to use a value-oriented investment style in the selection of securities for 
the Fund's portfolio. A convertible security is a bond, debenture, note, 
preferred stock or other security that may be converted into or exchanged for 
a prescribed amount of common stock of the same or a different issuer within 
a particular period of time at a specified price or based on a specified 
formula. Convertible securities rank senior to common stocks in a 
corporation's capital structure and, therefore, entail less risk than the 
corporation's common stock. The value of a convertible security is a function 
of its "investment value" (its value as if it did not have a conversion 
privilege), and its "conversion value" (the security's worth if it were to 

8
<PAGE>
be exchanged for the underlying security, at market value, pursuant to its 
conversion privilege). 

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

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

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

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

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

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

                                                                             9
<PAGE>
Aa by Moody's. Such securities may be used to invest uncommitted cash 
balances. 

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

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

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

WHEN, AS AND IF ISSUED SECURITIES. The Fund may purchase securities on a 
"when, as and if issued" basis under which the issuance of the security 
depends upon the occurrence of a subsequent event, such as approval of a 
merger, corporate reorganization, leveraged buyout or debt restructuring. If 
the anticipated event does not occur and the securities are not issued, the 
Fund will have lost an investment opportunity. An increase in the percentage 
of the Fund's assets committed to the purchase of securities on a "when, as 
and if issued" basis may increase the volatility of its net asset value. See 
the Statement of Additional Information for additional risk disclosure. 

INVESTMENT IN REAL ESTATE INVESTMENT TRUSTS. The Fund may invest in real 
estate investment trusts, which pool investors' funds for investments 
primarily in commercial real estate properties. Investment in real estate 
investment trusts may be the most practical available means for the Fund to 
invest in the real estate industry (the Fund is prohibited from investing in 
real estate directly). As a shareholder in a real estate investment trust, 
the Fund would bear its ratable share of the real estate investment trust's 
expenses, including its advisory and administration fees. At the same time 
the Fund would continue to pay its own investment management fees and other 
expenses, as a result of which the Fund and its shareholders in effect will 
be absorbing duplicate levels of fees with respect to investments in real 
estate investment trusts. 

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

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

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

RULE 144A SECURITIES. The Fund may invest up to 5% of its total assets in 
securities which are subject to restrictions on resale because they have not 
been registered under the Securities Act of 1933, as amended (the "Securities 
Act"), or which are otherwise not readily 

10
<PAGE>
marketable. (Securities eligible for resale pursuant to Rule 144A under the 
Securities Act, and determined to be liquid pursuant to the procedures 
discussed in the following paragraph, are not subject to the foregoing 
restriction.) These securities are generally referred to as private 
placements or restricted securities. Limitations on the resale of such 
securities may have an adverse effect on their marketability, and may prevent 
the Fund from disposing of them promptly at reasonable prices. The Fund may 
have to bear the expense of registering such securities for resale and the 
risk of substantial delays in effecting such registration. 

   The Securities and Exchange Commission has adopted Rule 144A under the 
Securities Act, which permits the Fund to buy securities restricted as to 
resale to qualified institutional buyers without limitation. The Investment 
Manager, pursuant to procedures adopted by the Trustees of the Fund, will 
make a determination as to the liquidity of each restricted security 
purchased by the Fund. If a restricted security is determined to be "liquid," 
such security will not be included within the category "illiquid securities," 
which under current policy may not exceed 15% of the Fund's net assets. 
However, investing in Rule 144A securities could have the effect of 
increasing the level of Fund illiquidity to the extent the Fund, at a 
particular point in time, may be unable to find qual ified institutional 
buyers interested in purchasing such securities. 

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

RISK CONSIDERATIONS 

The net asset value of the Fund's shares will fluctuate with changes in the 
market value of its portfolio securities. The market value of the Fund's 
portfolio securities will increase or decrease due to a variety of economic, 
market or political factors which cannot be predicted. The Fund's yield will 
also vary based on the yield of the Fund's portfolio securities. 

COMMON STOCKS, PREFERRED STOCKS AND SECURITIES CONVERTIBLE INTO COMMON 
STOCKS. The net asset value of the Fund's shares will fluctuate with changes 
in market values of portfolio securities. Convertible securities rank senior 
to common stocks in a corporation's capital structure and, therefore, entail 
less risk than the corporation's common stock. The value of a convertible 
security is a function of its "investment value" (its value as if it did not 
have a conversion privilege), and its "conversion value" (the security's 
worth if it were to be exchanged for the underlying security, at market 
value, pursuant to its conversion privilege). 

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

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

   The Fund may invest up to 25% of its total assets in "enhanced" 
convertible securities. Enhanced convertible securities offer holders the 
opportunity to obtain higher current income than would be available from a 
traditional equity security issued by the same company, in return for reduced 
participation or a cap on appreciation in the underlying common stock of the 
issuer which the holder 

                                                                            11
<PAGE>
can realize. In addition, in many cases, enhanced convertible securities are 
convertible into the underlying common stock of the issuer automatically at 
maturity, unlike traditional convertible securities which are convertible 
only at the option of the security holder. Enhanced convertible securities 
may be more volatile than traditional convertible securities due to the 
mandatory conversion feature. 

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

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

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

FOREIGN SECURITIES. Foreign securities investments may be affected by changes 
in currency rates or exchange control regulations, changes in governmental 
administration or economic or monetary policy (in the United States and 
abroad) or changed circumstances in dealings between nations. Fluctuations in 
the relative rates of exchange between the currencies of different nations 
will affect the value of the Fund's investments denominated in foreign 
currency. Changes in foreign currency exchange rates relative to the U.S. 
dollar will affect the U.S. dollar value of the Fund's assets denominated in 
that currency and thereby impact upon the Fund's total return on such assets. 

   Foreign currency exchange rates are determined by forces of supply and 
demand on the foreign exchange markets. These forces are themselves affected 
by the international balance of payments and other economic and financial 
conditions, government intervention, speculation and other factors. Moreover, 
foreign currency exchange rates may be affected by the regulatory control of 
the exchanges on which the currencies trade. 

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

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

LOWER RATED CONVERTIBLE AND FIXED-INCOME SECURITIES. A portion of the 
fixed-income and convertible securities in which the Fund may invest will 
generally be below investment grade. Securities below investment grade are 
the equivalent of high yield, high risk bonds, commonly known as "junk 
bonds." Investment grade is generally considered to be debt securities rated 
BBB or higher by Standard & Poor's Corporation ("S&P") or Baa or higher by 
Moody's Investors Service, Inc. ("Moody's"). Fixed- 

12
<PAGE>
income securities rated Baa by Moody's or BBB by Standard & Poor's have 
speculative characteristics greater than those of more highly rated bonds, 
while fixed-income securities rated Ba or BB or lower by Moody's and Standard 
& Poor's, respectively, are considered to be speculative investments. The 
Fund will not invest in convertibles and fixed-income securities that are 
rated lower than B by S&P or Moody's or, if not rated, determined to be of 
comparable quality by the Investment Manager. The Fund will not invest in 
debt securities that are in default in payment of principal or interest. The 
ratings of fixed-income securities by Moody's and Standard & Poor's are a 
generally accepted barometer of credit risk. However, as the creditworthiness 
of issuers of lower-rated fixed-income securities is more problematical than 
that of issuers of higher-rated fixed-income securities, the achievement of 
the Fund's investment objective will be more dependent upon the Investment 
Manager's own credit analysis than would be the case with a mutual fund 
investing primarily in higher quality bonds. The Investment Manager will 
utilize a security's credit rating as simply one indication of an issuer's 
creditworthiness and will principally rely upon its own analysis of any 
security currently held by the Fund or potentially purchasable by the Fund 
for its portfolio. 

   During the fiscal year ended September 30, 1997, the monthly dollar 
weighted average ratings of the debt obligations held by the Fund, expressed 
as a percentage of the Fund's total investments, were as follows: 

<TABLE>
<CAPTION>
                  PERCENTAGE OF 
   RATINGS      TOTAL INVESTMENTS 
- ------------  --------------------- 
<S>           <C>
AAA/Aaa .....           2.7% 
AA/Aa .......           0.0% 
A/A .........           0.6% 
BBB/Baa .....          18.7% 
BB/Ba .......          20.8% 
B/B .........          36.0% 
CCC/Caa .....           0.0% 
CC/Ca .......           0.0% 
C/C .........           0.0% 
Unrated .....          21.2% 
</TABLE>

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

CORPORATE NOTES AND BONDS AND U.S. GOVERNMENT SECURITIES. Payments of 
interest and principal of U.S. Government securities are guaranteed by the 
U.S. Government, however, neither the value nor the yield of corporate notes 
and bonds and U.S. Government securities which may be invested in by the Fund 
are guaranteed by the U.S. Government. Values and yield of corporate and 
government bonds will fluctuate with changes in prevailing interest rates and 
other factors. Generally, as prevailing interest rates rise, the value of 
corporate notes and bonds and government bonds held by the Fund will fall. 
Securities with longer maturities generally tend to produce higher yields and 
are subject to greater market fluctuation as a result of changes in interest 
rates than debt securities with shorter maturities. The Fund is not limited 
as to the maturities of the U.S. Government securities in which it may 
invest. 

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

REPURCHASE AGREEMENTS. While repurchase agreements involve certain risks not 
associated with direct investments in debt securities, including the risks of 
default or bankruptcy of the selling financial institution, the Fund follows 
procedures designed to minimize such risks. These procedures include 
effecting repurchase transactions only with large, well-capitalized and 
well-established financial institutions whose financial condition will be 
continually monitored by the Investment Manager subject to procedures 
established by the Board of Trustees of the Fund. In addition, as described 
above, the value of the collateral underlying the repurchase agreement will 
be at least equal to the repurchase price, including any accrued interest 
earned on the repurchase agreement. In the event of a default or bankruptcy 
by a selling financial institution, the Fund will seek to liquidate such 
collateral. However, the exercising of the Fund's right to liquidate such 
collateral could involve certain costs or delays and, 

                                                                            13
<PAGE>
to the extent that proceeds from any sale upon a default of the obligation to 
repurchase were less than the repurchase price, the Fund could suffer a loss. 
It is the current policy of the Fund not to invest in repurchase agreements 
that do not mature within seven days if any such investment, together with 
any other illiquid assets held by the Fund, amounts to more than 15% of its 
net assets. 

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

PORTFOLIO MANAGEMENT 

The Fund's portfolio is actively managed by its Investment Manager with a 
view to achieving the Fund's investment objective. In determining which 
securities to purchase for the Fund or hold in the Fund's portfolio, the 
Investment Manager will rely on information from various sources, including 
research, analysis and appraisals of brokers and dealers, including Dean 
Witter Reynolds Inc. ("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 it deems 
relevant. The Investment Manager also may use quantitative screens in the 
process of selecting portfolio securities. 

PORTFOLIO MANAGERS. The assets of the Fund are managed within InterCapital's 
Growth and Income Group, which manages 23 equity funds and fund portfolios 
with approximately $28.4 billion in assets as of October 31, 1997. Paul D. 
Vance, Senior Vice President and Michael G. Knox, Vice President of 
InterCapital, are members of InterCapital's Growth and Income Group. Mr. 
Vance has been a portfolio manager at InterCapital for over five years. Mr. 
Knox has been managing portfolios at InterCapital since August 1993. Prior to 
joining InterCapital, Mr. Knox was with Eagle Asset Management, Inc. Mr. 
Vance and Mr. Knox are portfolio managers with primary responsibility for the 
day-to-day management of the Fund's portfolio. 

   Although the Fund does not intend to engage in short-term trading of 
portfolio securities as a means of achieving its investment objective, it may 
sell portfolio securities without regard to the length of time they have been 
held whenever such sale will in the Investment Manager's opinion strengthen 
the Fund's position and contribute to its investment objective. The portfolio 
turnover rate is not expected to exceed 90%. Brokerage commissions are not 
normally charged on the purchase or sale of U.S. Government obligations, but 
such transactions may involve costs in the form of spreads between bid and 
asked prices. Pursuant to an order of the Securities and Exchange Commission, 
the Fund may effect principal transactions in certain money market 
instruments with DWR. In addition, the Fund may incur brokerage commissions 
on transactions conducted through DWR and other brokers and dealers that are 
affiliates of InterCapital. 

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

The investment restrictions listed below are among the restrictions which 
have been adopted by the Fund as fundamental policies. Under the Investment 
Company Act of 1940, as amended (the "Act"), a fundamental policy may not be 
changed without the vote of a majority of the outstanding voting securities 
of the Fund, as defined in the Act. For purposes of the following 
limitations: (i) all percentage limitations apply immediately after a 
purchase or initial investment; and (ii) any 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 the value of its total assets in the securities 
of any one issuer (other than obligations issued, or guaranteed by, the 
United States Government, its agencies or instrumentalities). 

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

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

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

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

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

GENERAL 

The Fund offers each Class of its shares for sale to the public on a continuous 
basis. Pursuant to a Distribution Agreement between the Fund and 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 which have entered into selected dealer agreements with the 
Distributor ("Selected Broker-Dealers"). The principal executive office of the 
Distributor is located at Two World Trade Center, New York, New York 10048. 

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

   The minimum initial purchase is $1,000 for each Class of shares, although 
Class D shares are only available to persons investing $5 million or more and 
to certain other limited categories of investors. For the purpose of meeting 
the minimum $5 million initial investment for Class D shares, and subject to 
the $1,000 minimum initial investment for each Class of the Fund, an 
investor's existing holdings of Class A shares of the Fund and other Dean 
Witter Funds that are multiple class funds ("Dean Witter Multi-Class Funds") 
and shares of Dean Witter Funds sold with a front-end sales charge ("FSC 
Funds") and concurrent investments in Class D shares of the Fund and other 
Dean Witter Multi-Class Funds will be aggregated. Subsequent purchases of 
$100 or more may be made by sending a check, payable to Dean Witter Income 
Builder Fund, directly to Dean Witter Trust FSB (the "Transfer Agent" or 
"DWT") 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 
(Service Mark), an automatic purchase plan (see "Shareholder Services"), is 
$100, provided that the schedule of automatic investments will result in 
investments totalling at least $1,000 within the first twelve months. The 
minimum initial purchase in the case of an "Education IRA" is $500, if the 
Distributor has reason to believe that additional investments will increase 
the investment in the account to $1,000 within three years. In the case of 
investments pursuant to (i) Systematic Payroll Deduction Plans (including 
Individual Retirement Plans), (ii) the InterCapital mutual fund asset 
allocation program and (iii) fee-based programs approved by the Distributor, 
pursuant to which participants pay an asset based fee for services in the 
nature of investment advisory or administrative services, the Fund, in its 
discretion, may accept investments without regard to any minimum amounts 
which would otherwise be required, provided, in the case of Systematic 
Payroll Deduction Plans, that the Distributor has reason to believe that 
additional investments will increase the investment in all accounts under 
such Plans to at least $1,000. Certificates for shares purchased will not be 
issued unless 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 

                                                                            15
<PAGE>
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." 

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

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

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

CLASS B SHARES. Class B shares are offered at net asset value with no initial 
sales charge but are subject to a CDSC (scaled down from 5.0% to 1.0%) if 
redeemed within six years of purchase. (Class B shares purchased by certain 
qualified employer-sponsored benefit plans are subject to a CDSC scaled down 
from 2.0% to 1.0% if redeemed within three years after purchase.) This CDSC 
may be waived for certain redemptions. Class B shares are also subject to an 
annual 12b-1 fee of 1.0% of the lesser of: (a) the average daily aggregate 
gross sales of the Fund's Class B shares since the inception of the Fund (not 
including reinvestments of dividends or capital gains distributions), less 
the average daily aggregate net asset value of the Fund's Class B shares 
redeemed since the Fund's inception upon which a CDSC has been imposed or 
waived, or (b) the average daily net assets of Class B. The Class B shares' 
distribution fee will cause that Class to have higher expenses and pay lower 
dividends than Class A or Class D shares. 

   After approximately ten (10) years, Class B shares will convert 
automatically to Class A shares of the Fund, based on the relative net asset 
values of the shares of the two Classes on the conversion date. In addition, 
a certain portion of Class B shares that have been acquired through the 
reinvestment of dividends and distributions will be converted at that time. 
See "Contingent Deferred Sales Charge Alternative--Class B Shares." 

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

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

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

16
<PAGE>
   The decision as to which Class of shares is more beneficial to an investor 
depends on the amount and intended length of his or her investment. Investors 
who prefer an initial sales charge alternative may elect to purchase Class A 
shares. Investors qualifying for significantly reduced or, in the case of 
purchases of $1 million or more, no initial sales charges may find Class A 
shares particularly attractive because similar sales charge reductions are 
not available with respect to Class B or Class C shares. Moreover, Class A 
shares are subject to lower ongoing expenses than are Class B or Class C 
shares over the term of the investment. As an alternative, Class B and Class 
C shares are sold without any initial sales charge so the entire purchase 
price is immediately invested in the Fund. Any investment return on these 
additional investment amounts may partially or wholly offset the higher 
annual expenses of these Classes. Because the Fund's future return cannot be 
predicted, however, there can be no assurance that this would be the case. 

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

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

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

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

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

INITIAL SALES CHARGE ALTERNATIVE-- 
CLASS A SHARES 

Class A shares are sold at net asset value plus an initial sales charge. In 
some cases, reduced sales charges may be available, as described below. 
Investments of $1 million or more (and investments by certain other limited 
categories of investors) are not subject to any sales charges at the time of 
purchase but are subject to a CDSC 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. 

                                                                            17

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

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

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

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

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

   The Distributor must be notified by DWR or a Selected Broker-Dealer or the 
shareholder at the time a purchase order is placed that the purchase 
qualifies for the reduced charge under the Right of Accumulation. Similar 
notification must be made in writing by the dealer or shareholder when such 
an order is placed by mail. The reduced sales charge will not be granted if: 
(a) such notification is not furnished at the time of the order; or (b) a 
review of the records of the Selected Broker-Dealer or the Transfer Agent 
fails to confirm the investor's represented holdings. 
<PAGE>
LETTER OF INTENT. The foregoing schedule of reduced sales charges will also 
be available to investors who enter into a written Letter of Intent providing 
for the purchase, within a thirteen-month period, of Class A shares of the 
Fund from DWR or other Selected Broker-Dealers. The cost of Class A shares of 
the Fund or shares of other Dean Witter Funds which were previously purchased 
at a price including a front-end sales charge during the 90-day period prior 
to the date of receipt by the Distributor of the Letter of Intent, or of 
Class A shares of the Fund or shares of other Dean Witter Funds acquired in 
exchange for shares of such funds purchased during such period at a price 
including a front-end sales charge, which are still owned by the shareholder, 
may also be included in determining the applicable reduction. 

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

18
<PAGE>
   (1) trusts for which DWT (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, mandatory redemption upon 
termination and such other circumstances as specified in the programs' 
agreements, 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 DWT 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 DWT serves as Trustee 
or the 401(k) Support Services Group of DWR serves as recordkeeper whose 
Class B shares have converted to Class A shares, regardless of the plan's 
asset size or number of eligible employees; 

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

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

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

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

CONTINGENT DEFERRED SALES CHARGE 
ALTERNATIVE--CLASS B SHARES 

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

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

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

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: 

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

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

   (3) all redemptions of shares held for the benefit of a participant in a 
401(k) plan or other employer-sponsored plan qualified under Section 401(a) 
of the Internal Revenue Code which offers investment companies managed by the 
Investment Manager or its subsidiary, Dean Witter Services Company Inc., as 
self-directed investment alternatives and for which DWT 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 DWT 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

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. 

LEVEL LOAD ALTERNATIVE--CLASS C SHARES 

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

NO LOAD ALTERNATIVE--CLASS D SHARES 

Class D shares are offered without any sales charge on purchase or redemption 
and without any 12b-1 fee. Class D shares are offered only to investors 
meeting an initial investment minimum of $5 million and the following 
categories of investors: (i) investors participating in the InterCapital 
mutual fund asset allocation program pursuant to which such persons pay an 
asset based fee; (ii) persons participating in a fee-based program approved 
by the Distributor, pursuant to which such persons pay an asset based fee for 
services in the nature of investment advisory or administrative services 
(subject to all of the terms and conditions of such programs, referred to in 
(i) and (ii) above, which may include termination fees, mandatory redemption 
upon termination and such other circumstances as specified in the programs' 
agreements, and restrictions on transferability of Fund shares); (iii) 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. Reimburse- 

                                                                            21
<PAGE>
ments for these expenses will be made in monthly payments by the Fund to the 
Distributor, which will in no event exceed amounts equal to payments at the 
annual rates of 0.25% and 1.0% of the average daily net assets of Class A and 
Class C, respectively. In the case of Class B shares, the Plan provides that 
the Fund will pay the Distributor a fee, which is accrued daily and paid 
monthly, at the annual rate of 1.0% of the lesser of: (a) the average daily 
aggregate gross sales of the Fund's Class B shares since the inception of the 
Fund (not including reinvestments of dividends or capital gains 
distributions), less the average daily aggregate net asset value of the 
Fund's Class B shares redeemed since the Fund's inception upon which a CDSC 
has been imposed or waived, or (b) the average daily net assets of Class B. 
The fee is treated by the Fund as an expense in the year it is accrued. In 
the case of Class A shares, the entire amount of the fee currently represents 
a service fee within the meaning of the NASD guidelines. In the case of Class 
B and Class C shares, a portion of the fee payable pursuant to the Plan, 
equal to 0.25% of the average daily net assets of each of these Classes, is 
currently characterized as a service fee. A service fee is a payment made for 
personal service and/or the maintenance of shareholder accounts. 

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

   For the fiscal year ended September 30, 1997, Class B shares of the Fund 
accrued payments under the Plan amounting to $2,268,574, which amount is 
equal to 0.91% of the average daily net assets of Class B for the fiscal 
year. These payments were calculated pursuant to clause (a) of the 
compensation formula under the Plan. All shares held prior to July 28, 1997 
have been designated Class B shares. For the period July 28 through September 
30, 1997, Class A and Class C shares of the Fund accrued payments under the 
Plan amounting to $175 and $869, respectively, which amounts on an annualized 
basis are equal to 0.25% and 1.00% of the average daily net assets of Class A 
and Class C, respectively, for such period. 

   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 $13,633,538 at September 30, 1997, which was equal to 3.80% of the 
net assets of Class B on such date. Because there is no requirement under the 
Plan that the Distributor be reimbursed for all distribution expenses or any 
requirement that the Plan be continued from year to year, such excess amount 
does not constitute a liability of the Fund. Although there is no legal 
obligation for the Fund to pay expenses incurred in excess of payments made 
to the Distributor under the Plan, and the proceeds of CDSCs paid by 
investors upon redemption of shares, if for any reason the Plan is terminated 
the Trustees will consider at that time the manner in which to treat such 
expenses. Any cumulative expenses incurred, but not yet recovered through 
distribution fees or CDSCs, may or may not be recovered through future 
distribution fees or CDSCs. 

   In the case of Class A and Class C shares, expenses incurred pursuant to 
the Plan in any calendar year in excess of 0.25% or 1.0% of the average daily 
net assets of Class A or Class C, respectively, will not be reimbursed by the 
Fund through payments in any subsequent year, except that expenses 
representing a gross sales commission credited to account executives at the 
time of sale may be reimbursed in the subsequent calendar year. No interest 
or other financing charges will be incurred on any Class A or Class C 
distribution expenses incurred by the Distributor under the Plan or on any 
unreimbursed expenses due to the Distributor pursuant to the Plan. 

DETERMINATION OF NET ASSET VALUE 

The net asset value per share is determined once daily at 4:00 p.m., New York 
time, on each day that the New York Stock Exchange is open (or, on days when 
the New York Stock Exchange closes prior to 4:00 p.m., at such earlier time), 
by taking the net assets of the Fund, dividing by the number of shares 
outstanding and adjusting to the 

22
<PAGE>
nearest cent. The assets belonging to the Class A, Class B, Class C and Class 
D shares will be invested together in a single portfolio. The net asset value 
of each Class, however, will be determined separately by subtracting each 
Class's accrued expenses and liabilities. The net asset value per share will 
not be determined on Good Friday and on such other federal and non-federal 
holidays as are observed by the New York Stock Exchange. 

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

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

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

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


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

SYSTEMATIC WITHDRAWAL PLAN. A systematic withdrawal plan (the "Withdrawal 
Plan") is available for shareholders who own or purchase shares of the Fund 
having a minimum value of $10,000 based upon the then current net asset 
value. The Withdrawal Plan provides for monthly or quarterly (March, June, 
September and December) checks in any 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 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. 

   Withdrawal Plan payments should not be considered as dividends, yields or 
income. If periodic withdrawal plan payments continuously exceed net 
investment 

                                                                            23
<PAGE>
income and net capital gains, the shareholder's original investment will be 
correspondingly reduced and ultimately exhausted. 

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

   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. 

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. ("Global Short-Term"), which is a Dean 
Witter Fund offered with a CDSC. 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, Global 
Short-Term or any Exchange Fund that is not a money market fund is on the 
basis of the next calculated net asset value per share of each fund after the 
exchange order is received. When exchanging into a money market fund from the 
Fund, shares of the Fund are redeemed out of the Fund at their next 
calculated net asset value and the proceeds of the redemption are used to 
purchase shares of the money market fund at their net asset value determined 
the following day. Subsequent exchanges between any of the money market funds 
and any of the Dean Witter Multi-Class Funds, FSC Funds, Global Short-Term 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 Global Short-Term, 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 
Global Short-Term 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 Global Short-Term (see "Purchase 
of Fund Shares"). In the case of exchanges of Class A shares which are 
subject to a CDSC, the holding period also includes the time (calculated as 
described above) the shareholder was invested in shares of a FSC Fund. In the 
case of shares exchanged into an Exchange Fund on or after April 23, 1990, 
upon a redemption of shares which results in a CDSC being imposed, a credit 
(not to exceed the amount of the CDSC) will be given in an amount equal to 
the Exchange Fund 12b-1 distribution fees incurred on or after that date 
which are attributable to those shares. (Exchange Fund 12b-1 distribution 
fees are described in the prospectuses for those funds.) Class B shares of 
the Fund acquired in exchange for shares of Global Short-Term or Class B 
shares of another Dean Witter Multi-Class Fund having a different CDSC 
schedule than that of this Fund will be subject to the higher CDSC schedule, 
even if such shares are subsequently re-exchanged for shares of the fund with 
the lower CDSC schedule. 

ADDITIONAL INFORMATION REGARDING EXCHANGES. Purchases and exchanges should be 
made for investment purposes only. A pattern of frequent exchanges may be 
deemed by the Investment Manager to be abusive and contrary to the best 
interests of the Fund's other shareholders and, at the Investment Manager's 
discretion, may be limited by the Fund's refusal to accept additional 
purchases and/or exchanges from the investor. Although the Fund does not have 
any specific definition of what constitutes a pattern of frequent exchanges, 
and will consider all relevant factors in determining whether a particular 
situation is abusive and contrary to the best interests of the Fund and its 
other shareholders, investors should be aware that the Fund and each of the 
other 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 

24
<PAGE>
such shareholder's most recent exchange. Also, the Exchange Privilege may be 
terminated or revised at any time by the Fund and/or any of such Dean Witter 
Funds for which shares of the Fund have been exchanged, upon such notice as 
may be required by applicable regulatory agencies. Shareholders maintaining 
margin accounts with DWR or another Selected Broker-Dealer are referred to 
their account executive regarding restrictions on exchange of shares of the 
Fund pledged in the margin account. 

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

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

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

   Telephone exchange instructions will be accepted if received by the 
Transfer Agent between 9:00 a.m. and 4:00 p.m., New York time, on any day the 
New York Stock Exchange is open. Any shareholder wishing to make an exchange 
who has previously filed an Exchange Privilege Authorization Form and who is 
unable to reach the Fund by telephone should contact his or her 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 other Dean Witter Funds in the past. 

   Additional information on the above is available from an account executive 
of DWR or another Selected Broker-Dealer or from the Transfer Agent. 

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

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

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

   The CDSC, if any, will be the only fee imposed by the Fund or the 
Distributor. The offer by DWR and other 

                                                                            25
<PAGE>
Selected Broker-Dealers to repurchase shares may be suspended without notice 
by them at any time. In that event, shareholders may redeem their shares 
through the Fund's Transfer Agent as set forth above under "Redemption." 

PAYMENT FOR SHARES REDEEMED OR REPURCHASED. Payment for shares presented for 
repurchase or redemption will be made by check within seven days after 
receipt by the Transfer Agent of the certificate and/or written request in 
good order. Such payment may be postponed or the right of redemption 
suspended under unusual circumstances, e.g., when normal trading is not 
taking place on the New York Stock Exchange. If the shares to be redeemed 
have recently been purchased by check, payment of the redemption proceeds may 
be delayed for the minimum time needed to verify that the check used for 
investment has been honored (not more than fifteen days from the time of 
receipt of the check by the Transfer Agent). Shareholders maintaining margin 
accounts with DWR or another Selected Broker-Dealer are referred to their 
account 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 to redeem, upon sixty 
days' notice and at net asset value, the shares of any shareholder (other 
than shares held in an Individual Retirement Account or Custodial Account 
under Section 403(b)(7) of the Internal Revenue Code) whose shares have a 
value of less than $100 as a result of redemptions or repurchases, or such 
lesser amount as may be fixed by the Board of Trustees or, in the case of an 
account opened through 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 to make an additional investment 
in an amount which will increase the value of the account to at least the 
applicable amount before the redemption is processed. No CDSC will be imposed 
on any involuntary redemption. 

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

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

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

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

   Distributions of net long-term capital gains, if any, are taxable to 
shareholders as long-term capital gains regardless of how long a shareholder 
has held the Fund's 

26
<PAGE>
shares and regardless of whether the distribution is received in additional 
shares or in cash. Capital gains distributions are not eligible for the 
dividends received deduction. 

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

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

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

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

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

   From time to time the Fund may quote its "total return" in advertisements 
and sales literature. These figures are computed separately for Class A, 
Class B, Class C and Class D shares. The total return of the Fund is based on 
historical earnings and is not intended to indicate future performance. The 
"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. Total return and average annual total return reflect all income 
earned by the Fund, any appreciation or depreciation of the Fund's assets, 
all expenses incurred by the applicable Class and all sales charges which 
will be incurred by shareholders, for the stated periods. It also assumes 
reinvestment of all dividends and distributions paid by the Fund. 

   In addition to the foregoing, the Fund may advertise its total return for 
each Class over different periods of time by means of aggregate, average, 
year-by-year or other types of total return figures. The Fund may also 
advertise the growth of hypothetical investments of $10,000, $50,000 and 
$100,000 in each Class of shares of the Fund. Such calculations may or may 
not reflect the deduction of any sales charge which, if reflected, would 
reduce the performance quoted. The Fund from time to time may also advertise 
its performance relative to certain performance rankings and indexes compiled 
by independent organizations (such as mutual fund performance rankings of 
Lipper Analytical Services, Inc., the S&P 500 Index and the Lehman Brothers 
Government/Corporate Bond Index). 

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

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

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

                                                                            27

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

CODE OF ETHICS. Directors, officers and employees of InterCapital, Dean 
Witter Services Company Inc. and the Distributor are subject to a strict Code 
of Ethics adopted by those companies. The Code of Ethics is intended to 
ensure that the interests of shareholders and other clients are placed ahead 
of any personal interest, that no undue personal benefit is obtained from a 
person's employment activities and that actual and potential conflicts of 
interest are avoided. To achieve these goals and comply with regulatory 
requirements, the Code of Ethics requires, among other things, that personal 
securities transactions by employees of the companies be subject to an 
advance clearance process to monitor that no Dean Witter Fund is engaged at 
the same time in a purchase or sale of the same security. The Code of Ethics 
bans the purchase of securities in an initial public offering and prohibits 
engaging in futures and options transactions and profiting on short-term 
trading (that is, a purchase within 60 days of a sale or a sale within 60 
days of a purchase) of a security. In addition, investment personnel may not 
purchase or sell a security for their personal account within 30 days before 
or after any transaction in any 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.
