JULY 28, 1997
    
 
              Dean Witter High Yield
Securities Inc. (the "Fund") is an open-end diversified management investment
company whose primary investment objective is to earn a high level of current
income. As a secondary objective, the Fund will seek capital appreciation, but
only when consistent with its primary objective. The Fund seeks high current
income by investing principally in fixed-income securities which are rated in
the lower categories by established rating services (Baa or lower by Moody's
Investors Service, Inc. or BBB or lower by Standard & Poor's Corporation) or are
non-rated securities of comparable quality.
               INVESTORS SHOULD CAREFULLY CONSIDER THE RELATIVE RISKS, INCLUDING
THE RISK OF DEFAULT, OF INVESTING IN HIGH YIELD SECURITIES, WHICH ARE COMMONLY
KNOWN AS JUNK BONDS. BONDS OF THIS TYPE ARE CONSIDERED TO BE SPECULATIVE WITH
REGARD TO THE PAYMENT OF INTEREST AND RETURN OF PRINCIPAL. INVESTORS SHOULD ALSO
BE COGNIZANT OF THE FACT THAT SUCH SECURITIES ARE NOT GENERALLY MEANT FOR SHORT-
TERM INVESTING AND SHOULD ASSESS THE RISKS ASSOCIATED WITH AN INVESTMENT IN THE
FUND. (See "Investment Objectives and Policies.")
 
   
               The Fund offers four classes of shares (each, a "Class"), each
with a different combination of sales charges, ongoing fees and other features.
The different distribution arrangements permit an investor to choose the method
of purchasing shares that the investor believes is most beneficial given the
amount of the purchase, the length of time the investor expects to hold the
shares and other relevant circumstances. Shares of the Fund held prior to July
28, 1997 have been designated Class D shares. (See "Purchase of Fund
Shares--Alternative Purchase Arrangements.")
    
 
   
               This Prospectus sets forth concisely the information you should
know before investing in the Fund. It should be read and retained for future
reference. Additional information about the Fund is contained in the Statement
of Additional Information, dated July 28, 1997, which has been filed with the
Securities and Exchange Commission, and which is available at no charge upon
request of the Fund at the address or telephone numbers listed on this page. The
Statement of Additional Information is incorporated herein by reference.

and               to Rule 12b-1 under the Investment Company Act (the "12b-1 Plan") with respect to the distribution
Distribution      fees paid by the Class A, Class B and Class C shares of the Fund to the Distributor. The entire
Fee               12b-1 fee payable by Class A and a portion of the 12b-1 fee payable by each of Class B and Class C
                  equal to 0.20% of the average daily net assets of Class B and 0.25% of the average daily net assets
                  of Class C are currently each characterized as a service fee within the meaning of the National
                  Association of Securities Dealers, Inc. guidelines. The remaining portion of the 12b-1 fee, if any,
                  is characterized as an asset-based sales charge
                  (see pages 14 and 23).
- ----------------------------------------------------------------------------------------------------------------------
Alternative       Four classes of shares are offered:
Purchase
Arrangements      - Class A shares are offered with a front-end sales charge, starting at 4.25% and reduced for larger
                  purchases. Investments of $1 million or more (and investments by certain other limited categories of
                  investors) are not subject to any sales charge at the time of purchase but a contingent deferred
                  sales charge ("CDSC") of 1.0% may be imposed on redemptions within one year of purchase. The Fund is
                  authorized to reimburse the Distributor for specific expenses incurred in promoting the distribution
                  of the Fund's Class A shares and servicing shareholder accounts pursuant to the Fund's 12b-1 Plan.
                  Reimbursement may in no event exceed an amount equal to payments at an annual rate of 0.25% of
                  average daily net assets of the Class (see pages 14, 17 and 23).

<TABLE>
<S>               <C>
                  - Class B shares are offered without a front-end sales charge, but will in most cases be subject to
                  a CDSC (scaled down from 5.0% to 1.0%) if redeemed within six years after purchase. The CDSC will be
                  imposed on any redemption of shares if after such redemption the aggregate current value of a Class
                  B account with the Fund falls below the aggregate amount of the investor's purchase payments made
                  during the six years preceding the redemption. A different CDSC schedule applies to investments by
                  certain qualified plans. Class B shares are also subject to a 12b-1 fee assessed at the annual rate
                  of 0.75% of the average daily net assets of Class B. Class B shares convert to Class A shares
                  approximately ten years after the date of the original purchase (see pages 14, 20 and 23).
                  - Class C shares are offered without a front-end sales charge, but will in most cases be subject to
                  a CDSC of 1.0% if redeemed within one year after purchase. The Fund is authorized to reimburse the
                  Distributor for specific expenses incurred in promoting the distribution of the Fund's Class C
                  shares and servicing shareholder accounts pursuant to the Fund's 12b-1 Plan. Reimbursement may in no
                  event exceed an amount equal to payments at an annual rate of 0.85% of average daily net assets of
                  the Class (see pages 14, 22 and 23).
                  - Class D shares are offered only to investors meeting an initial investment minimum of $5 million
                  and to certain other limited categories of investors. Class D shares are offered without a front-end
                  sales charge or CDSC and are not subject to any 12b-1 fee (see pages 14, 22 and 23. All shares of
                  the Fund held prior to July 28, 1997 have been designated Class D shares. Additional investments in
                  Class D shares by shareholders holding such shares may only be made if those shareholders are
                  otherwise eligible to purchase Class D shares. However, shareholders holding such shares will
                  receive the benefit of the value of such shares towards reduced sales charges on purchases of Class
                  A shares pursuant to the Fund's "Right of Accumulation" (see page 18).
- ----------------------------------------------------------------------------------------------------------------------
Dividends         Dividends from net investment income are declared and paid monthly; distributions from net capital
and               gains, if any, are paid at least annually. The Fund may, however, determine to retain all or part of
Capital Gains     any net long-term capital gains in any year for reinvestment. Dividends and capital gains
Distributions     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 25
                  and 29).
- ----------------------------------------------------------------------------------------------------------------------
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-SM-, if after twelve
                  months the shareholder has invested less than $1,000 in the account (see page 28).
- ----------------------------------------------------------------------------------------------------------------------
Risks             The net asset value of the Fund's shares will fluctuate with changes in the market value of its
                  portfolio securities. The Fund's yield will also vary based on the yield of the Fund's portfolio
                  securities. Compared with higher rated, lower yielding fixed-income securities, portfolio securities
                  of the Fund may be subject to greater risk of loss of income and principal, including the risk of
                  default, and greater risk of increases and decreases in net asset value due to market fluctuations.
                  The Fund may purchase foreign securities, when-issued and delayed delivery and when, as and if
                  issued securities and other securities subject to repurchase agreements which involve certain
                  special risks. The Fund may purchase common stock which is exchangeable for fixed-income securities
                  in circumstances involving takeovers or recapitalizations. The Fund may also invest in futures and
                  options which may be considered speculative in nature and may involve greater risks than those
                  customarily assumed by certain other investment companies which do not invest in such instruments.
                  Investors should review the investment objectives and policies of the Fund carefully and consider
                  their ability to assume the risks involved in purchasing shares of the Fund (see pages 7-14).

(2) INVESTMENTS THAT ARE NOT SUBJECT TO ANY SALES CHARGE AT THE TIME OF PURCHASE
    ARE SUBJECT TO A CDSC OF 1.00% THAT WILL BE IMPOSED ON REDEMPTIONS MADE
    WITHIN ONE YEAR AFTER PURCHASE, EXCEPT FOR CERTAIN SPECIFIC CIRCUMSTANCES
    (SEE "PURCHASE OF FUND SHARES--INITIAL SALES CHARGE ALTERNATIVE--CLASS A
    SHARES").
    
 
   
(3) THE CDSC IS SCALED DOWN ANNUALLY TO 1.00% DURING THE SIXTH YEAR, REACHING
    ZERO THEREAFTER.
    
 
   
(4) ONLY APPLICABLE TO REDEMPTIONS MADE WITHIN ONE YEAR AFTER PURCHASE (SEE
    "PURCHASE OF FUND SHARES-- LEVEL LOAD ALTERNATIVE--CLASS C SHARES").
    
 
   
(5) THE 12B-1 FEE IS ACCRUED DAILY AND PAYABLE MONTHLY. THE ENTIRE 12B-1 FEE
    PAYABLE BY CLASS A AND A PORTION OF THE 12B-1 FEE PAYABLE BY EACH OF CLASS B
    AND CLASS C EQUAL TO 0.20% OF THE AVERAGE DAILY NET ASSETS OF CLASS B AND
    0.25% OF THE AVERAGE DAILY NET ASSETS OF CLASS C ARE CURRENTLY EACH
    CHARACTERIZED AS A SERVICE FEE WITHIN THE MEANING OF NATIONAL ASSOCIATION OF
    SECURITIES DEALERS, INC. ("NASD") GUIDELINES AND ARE PAYMENTS MADE FOR
    PERSONAL SERVICE AND/OR MAINTENANCE OF SHAREHOLDER ACCOUNTS. THE REMAINDER
    OF THE 12B-1 FEE, IF ANY, IS AN ASSET-BASED SALES CHARGE, AND IS A
    DISTRIBUTION FEE PAID TO THE DISTRIBUTOR TO COMPENSATE IT FOR THE SERVICES
    PROVIDED AND THE EXPENSES BORNE BY THE DISTRIBUTOR AND OTHERS IN THE
    DISTRIBUTION OF THE FUND'S SHARES (SEE "PURCHASE OF FUND SHARES--PLAN OF

(6) UPON CONVERSION OF CLASS B SHARES TO CLASS A SHARES, SUCH SHARES WILL BE
    SUBJECT TO THE LOWER 12B-1 FEE APPLICABLE TO CLASS A SHARES. NO SALES CHARGE
    IS IMPOSED AT THE TIME OF CONVERSION OF CLASS B SHARES TO CLASS A SHARES.
    CLASS C SHARES DO NOT HAVE A CONVERSION FEATURE AND, THEREFORE, ARE SUBJECT
    TO AN ONGOING 0.85% DISTRIBUTION FEE (SEE "PURCHASE OF FUND
    SHARES--ALTERNATIVE PURCHASE ARRANGEMENTS").
    
 
   
(7) THERE WERE NO OUTSTANDING SHARES OF CLASS A, CLASS B OR CLASS C PRIOR TO THE

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
    Dean Witter High Yield Securities Inc. (the "Fund") is an open-end
diversified management investment company incorporated in Maryland on June 14,
1979.
 
   
    Dean Witter InterCapital Inc. ("InterCapital" or the "Investment Manager"),
whose address is Two World Trade Center, New York, New York 10048, is the Fund's
Investment Manager. The Investment Manager, which was incorporated in July,
1992, is a wholly-owned subsidiary of Morgan Stanley, Dean Witter, Discover &
Co., a preeminent global financial services firm that maintains leading market
positions in each of its three primary businesses--securities, asset management
and credit services.
    
 
   
    InterCapital and its wholly-owned subsidiary, Dean Witter Services Company
Inc., serve in various investment management, advisory, management and
administrative capacities to 100 investment companies, thirty of which are
listed on the New York Stock Exchange, with combined total assets of
approximately $    billion as of June 30, 1997. The Investment Manager also
manages, and advises managers of, common stock portfolios of pension plans,
other institutions and individuals which aggregated approximately $    billion
at such date.
    
 
    The Fund has retained the Investment Manager to provide administrative
services, manage its business affairs and manage the investment of the Fund's
assets, including the placing of orders for the purchase and sale of portfolio
securities. InterCapital has retained Dean Witter Services Company Inc. to
perform the aforementioned administrative services for the Fund.
 
    The Fund's Board of Directors reviews the various services provided by or
under the direction of the Investment Manager to ensure that the Fund's general
investment policies and programs are being properly carried out and that
administrative services are being provided to the Fund in a satisfactory manner.
 
    As full compensation for the services and facilities furnished to the Fund
and expenses of the Fund assumed by the Investment Manager, the Fund pays the
Investment Manager monthly compensation calculated daily by applying a
percentage rate to the daily net assets of the Fund which declines as net assets
of the Fund reach levels over $500 million (up to $3 billion). For the fiscal
year ended August 31, 1996, the Fund accrued total compensation to the
Investment Manager amounting to 0.50% of the Fund's average daily net assets and
the Fund's total expenses amounted to 0.66% of the Fund's average daily net
assets.
 
INVESTMENT OBJECTIVES AND POLICIES
- --------------------------------------------------------------------------------
 
    The primary investment objective of the Fund is to earn a high level of
current income. As a secondary objective, the Fund will seek capital
appreciation, but only when consistent with its primary objective. Capital
appreciation may result, for example, from an improvement in the credit standing
of an issuer whose securities are held in the Fund's portfolio or from a general
decline in interest rates, or a combination of both. Conversely, capital
depreciation may result, for example, from a lowered credit standing or a
general rise in interest rates, or a combination of both. There is no assurance
that the objectives will be achieved.
    The higher yields sought by the Fund are generally obtainable from
securities rated in the lower categories by recognized rating services. The Fund
seeks high current income by investing principally in fixed-income securities
rated Baa or lower by Moody's Investors Service, Inc. ("Moody's"), or BBB or
lower by Standard & Poor's Corporation ("Standard & Poor's"). Fixed-income
securities rated Baa by Moody's or BBB by Standard & Poor's
 
                                       7
<PAGE>
have speculative characteristics greater than those of more highly rated bonds,
while fixed-income securities rated Ba or BB or lower by Moody's and Standard &
Poor's, respectively, are considered to be speculative investments. Furthermore,
the Fund does not have any minimum quality rating standard for its investments.
As such, the Fund may invest in securities rated as low as Caa, Ca or C by
Moody's or CCC, CC, C or C1 by Standard & Poor's. Fixed-income securities rated
Caa or Ca by Moody's may already be in default on payment of interest or
principal, while bonds rated C by Moody's, their lowest bond rating, can be
regarded as having extremely poor prospects of ever attaining any real
investment standing. Bonds rated C1 by Standard & Poor's, their lowest bond
rating, are no longer making interest payments. For a further discussion of the
characteristics and risks associated with high yield securities, see "Special
Investment Considerations" below. A description of corporate bond ratings is
contained in the Appendix.
 
    Non-rated securities will also be considered for investment by the Fund when
the Investment Manager believes that the financial condition of the issuers of
such securities, or the protection afforded by the terms of the securities
themselves, makes them appropriate investments for the Fund.
 
    In circumstances where the Investment Manager determines that investment in
municipal obligations would facilitate the Fund's ability to accomplish its
investment objectives, it may invest up to 10% of its total assets in such
obligations, including municipal bonds issued at a discount.
 
    All fixed-income securities are subject to two types of risks: the credit
risk and the interest rate risk. The credit risk relates to the ability of the
issuer to meet interest or principal payments or both as they come due.
Generally, higher yielding bonds are subject to a credit risk to a greater
extent than higher quality bonds. The interest rate risk refers to the
fluctuations in net asset value of any portfolio of fixed-income securities
resulting solely from the inverse relationship between price and yield of
fixed-income securities; that is, when the general level of interest rates
rises, the prices of outstanding fixed-income securities generally decline, and
when interest rates fall, prices generally rise.
 
    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.
 
    In determining which securities to purchase or hold for the Fund's portfolio
and in seeking to reduce credit and interest rate risks, the Investment Manager
will rely on information from various sources, including: the rating of the
security; research, analysis and appraisals of brokers and dealers, including
DWR; the views of the Fund's directors and others regarding economic
developments and interest rate trends; and the Investment Manager's own analysis
of factors it deems relevant. The extent to which the Investment Manager is
successful in reducing depreciation or losses arising from either interest rate
or credit risks depends in part on the Investment Manager's portfolio management
skills and judgment in evaluating the factors affecting the value of securities.
No assurance can be given regarding the degree of success that will be achieved.
 
SPECIAL RISK CONSIDERATIONS
 
   
    The net asset value of the Fund's shares will fluctuate with changes in the
market value of its portfolio securities. The Fund's yield will also vary based
on the yield of the Fund's portfolio securities.

    Because of the special nature of the Fund's investment in high yield
securities, commonly known as junk bonds, the Investment Manager must take
account of certain special considerations in assessing the risks associated with
such investments. Although the growth of the high yield securities market in the
1980s had paralleled a long economic expansion, recently many issuers have been
affected by adverse economic and market conditions. It should be recognized that
an economic downturn or increase in interest rates is likely to have a negative
effect on the high yield bond market and on the value of the high yield
securities held by the Fund, as well as on the ability of the securities'
issuers to repay principal and interest on their borrowings.
 
    The prices of high yield securities have been found to be less sensitive to
changes in prevailing interest rates than higher-rated investments, but are
likely to be more sensitive to adverse economic changes or individual corporate
developments. During an economic downturn or substantial period of rising
interest rates, highly leveraged issuers may experience financial stress which
would adversely affect their ability to service their principal and interest
payment obligations, to meet their projected business goals or to obtain
additional financing. If the issuer of a fixed-income security owned by the Fund
defaults, the Fund may incur additional expenses to seek recovery. In addition,
periods of economic uncertainty and change can be expected to result in an
increased volatility of market prices of high yield securities and a concomitant
volatility in the net asset value of a share of the Fund. Moreover, the market
prices of certain of the Fund's portfolio securities which are structured as
zero coupon and payment-in-kind securities are affected to a greater extent by
interest rate changes and thereby tend to be more volatile than securities which
pay interest periodically and in cash (see "Dividends, Distributions and Taxes"
for a discussion of the tax ramifications of investments in such securities).
 
    The secondary market for high yield securities may be less liquid than the
markets for higher quality securities and, as such, may have an adverse effect
on the market prices of certain securities. The limited liquidity of the market
may also adversely affect the ability of the Fund's Directors to arrive at a
fair value for certain high yield securities at certain times and could make it
difficult for the Fund to sell certain securities. In addition, new laws and
potential new laws may have an adverse effect upon the value of high yield
securities and a concomitant negative impact upon the net asset value of a share
of the Fund.
 
    During the fiscal year ended August 31, 1996, the monthly dollar weighted
average ratings of the debt obligations held by the Fund, expressed as a
percentage of the Fund's total investments, were as follows:
 
<TABLE>

  Unrated                             6.0%
</TABLE>
 
    Consistent with its primary investment objective, the Fund anticipates that,
under normal conditions, at least 65% of the value of its total assets will be
invested in the lower-rated and non-rated fixed-income securities previously
described. However, when the difference between yields derived from such
securities and those derived from higher rated issues are relatively narrow, the
Fund may invest in the higher rated issues since they may provide similar yields
with somewhat less risk. Fixed-income securities appropriate for the Fund may
include both convertible and nonconvertible debt securities and preferred stock.
 
    Pending investment of proceeds from the sale of shares of the Fund or of its
portfolio securities or
 
                                       9
<PAGE>
at other times when market conditions dictate a more "defensive" investment
strategy, the Fund may invest without limit in money market instruments,
including commercial paper of corporations organized under the laws of any state
or political subdivision of the United States, certificates of deposit, bankers'
acceptances and other obligations of domestic banks or domestic branches of
foreign banks, or foreign branches of domestic banks, in each case having total
assets of at least $500 million, and obligations issued or guaranteed by the
United States Government (including zero coupon securities), or foreign
governments or their respective instrumentalities or agencies. The yield on
these securities will generally tend to be lower than the yield on other
securities to be purchased by the Fund. 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 economic developments which might adversely affect the payment
of principal or interest.
 
    PUBLIC UTILITIES.  The Fund's investments in public utilities, if any, may
be subject to certain risks incurred by the Fund due to Federal, State or
municipal regulatory changes, insufficient rate increases or cost overruns.
 
    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 risk of default or
bankruptcy of the selling institution, the Fund follows procedures designed to
minimize such risks.
 
    WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. The Fund may purchase
securities on a when-issued or delayed delivery basis; I.E., delivery and
payment can take place a month or more after the date of the transaction. These
securities are subject to market fluctuation and no interest accrues to the
purchaser prior to settlement. At the time the Fund makes the commitment to
purchase such securities, it will re-cord the transaction and thereafter reflect
the value, each day, of such security in determining its net asset value. An
increase in the percentage of the Fund's assets committed to the purchase of
securities on a when-issued or delayed delivery basis may increase the
volatility of the Fund's net asset value.
 
    WHEN, AS AND IF ISSUED SECURITIES.  The Fund may purchase securities on a
"when, as and if issued" basis under which the issuance of the security depends
upon the occurrence of a subsequent event, such as approval of a merger,
corporate reorganization, leveraged buyout or debt restructuring. If the
anticipated event does not occur and the securities are not issued, the Fund
will have lost an investment opportunity. There is no overall limit on the
percentage of the Fund's assets which may be committed to the purchase of
securities on a "when, as and if issued" basis. An increase in the percentage of
the Fund's assets committed to the purchase of securities on a "when, as and if
issued" basis may increase the volatility of its net asset value.
 
    FOREIGN SECURITIES.  The Fund may invest up to 20% of its total assets in
fixed-income securities issued by foreign governments and other foreign issuers
and in foreign currency issues of domestic issuers, but not more than 10% of its
total assets in such securities, whether issued by a foreign or domestic issuer,
which are denominated in foreign currency. Foreign securities investments may be
affected by changes in currency rates or exchange
 
                                       10
<PAGE>
control regulations, changes in governmental administration or economic or
monetary policy (in the United States and abroad) or changed circumstances in
dealings between nations. Costs will be incurred in connection with conversions
between various currencies held by the Fund.
 
    Investments in foreign securities will also occasion risks relating to
political and economic developments abroad, including the possibility of
expropriations or confiscatory taxation, limitations on the use or transfer of
Fund assets and any effects of foreign social, economic or political
instability. Foreign companies are not subject to the regulatory requirements of
U.S. companies and, as such, there may be less publicly available information
about such companies. Moreover, foreign companies are not subject to uniform
accounting, auditing and financial reporting standards and requirements
comparable to those applicable to U.S. companies. Finally, in the event of a
default of any foreign debt obligations, it may be more difficult for the Fund
to obtain or enforce a judgment against the issuers of such securities.
 
    Securities of foreign issuers may be less liquid than comparable securities
of U.S. issuers and, as such, their price changes may be more volatile.
Furthermore, foreign exchanges and broker-dealers are generally subject to less
government and exchange scrutiny and regulation than their American
counterparts. Brokerage commissions, dealer concessions and other transaction
costs may be higher on foreign markets than in the U.S. In addition, differences
in clearance and settlement procedures 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.
 
   
    COMMON STOCKS.  The Fund may invest in common stocks in an amount up to 20%
of its total assets. The Fund may directly purchase common stocks on the open
market. In addition, the Fund may acquire common stocks when they are included
in a unit with fixed-income securities purchased by the Fund; when fixed-income
securities held by the Fund are converted to equity issues; when the Fund
exercises a warrant; and when the Fund purchases the common stock of companies
involved in takeovers or recapitalizations, where the issuer or a stockholder
has offered, or pursuant to a "going private" transaction is effecting, a
transaction involving the issuance of newly issued fixed-income securities to
the holders of such common stock.
    
 
   
    The prices of common stock are generally more volatile than those of
fixed-income securities. Moreover, not all common stock pay dividends and those
that do generally pay lower amounts than most fixed-income securities. The Fund
will only purchase common stocks directly when the Investment Manager believes
that their purchase will assist the Fund in meeting its investment objectives.
    
 
    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
 
                                       11
<PAGE>
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.
 
    FUTURES CONTRACTS AND OPTIONS ON FUTURES. The Fund may invest in financial
futures contracts ("futures contracts") and related options thereon. The Fund
may sell a futures contract or a call option thereon or purchase a put option on
such futures contract, if the Investment Manager anticipates interest rates to
rise, as a hedge against a decrease in the value of the Fund's portfolio
securities. If the Investment Manager anticipates that interest rates will
decline, the Fund may purchase a futures contract or a call option thereon or
sell a put option on such futures contract to protect against an increase in the
price of the securities the Fund intends to purchase. These futures contracts
and related options thereon will be used only as a hedge against anticipated
interest rate changes.
 
    The Fund may not enter into futures contracts or purchase related options
thereon if immediately thereafter the amount committed to margin plus the amount
paid for premiums for unexpired options on futures contracts exceeds 5% of the
value of the Fund's total assets. The Fund may not purchase or sell futures
contracts or related options thereon if, immediately thereafter, more than
one-third of its net assets would be hedged.
 
    OPTIONS.  The Fund may purchase or sell (write) listed options on debt
securities as a means of achieving additional return or of hedging the value of
the Fund's portfolio. The Fund may only write covered options which are listed
on national securities exchanges. The Fund may not write covered options in an
amount exceeding 20% of the value of its total assets. The Fund may only buy
options which are listed on national securities exchanges. The Fund will not
purchase options if, as a result, the aggregate cost of all outstanding options
exceeds 10% of the Fund's total assets.
 
    For a discussion of futures and options, including the risks of such
transactions, see the Statement of Additional Information.
 
    PRIVATE PLACEMENTS.  The Fund may invest up to 5% of its total assets in
securities which are subject to restrictions on resale because they have not
been registered under the Securities Act of 1933, as amended (the "Securities
Act"), or which are otherwise not readily marketable. (See "Investment
Restrictions" in the Statement of Additional Information.) 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 sell restricted securities to
qualified institutional buyers without limitation. The Investment Manager,
pursuant to procedures adopted by the Board of Directors 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 considered to be "restricted" for purposes of the above-disclosed 5%
limitation and will not be included within the category "illiquid securities,"
which under current policy may not exceed 15% of the Fund's total assets.
However, investing in Rule 144A securities could have the effect of increasing
the level of Fund illiquidity to the extent the Fund, at a particular point of
time, may be unable to find qualified institutional buyers interested in
purchasing such securities.

PORTFOLIO MANAGEMENT
 
   
    The Fund is actively managed by the Investment Manager with a view to
achieving the Fund's investment objective. The Fund is managed within
InterCapital's Taxable Income Group, which managed approximately $    billion in
assets at June 30, 1997. Peter M. Avelar, Senior Vice President of InterCapital
and a member of InterCapital's Taxable Fixed-Income Group, has been the primary
portfolio manager of the Fund since January, 1991 and has been managing fixed
portfolios consisting of fixed-income and equity securities at InterCapital for
over five years.
    
 
   
    Securities purchased by the Fund are, generally, sold by dealers acting as
principal for their own accounts. Pursuant to an order issued by the Securities
and Exchange Commission, the Fund may effect principal transactions in certain
money market instruments with Dean Witter Reynolds Inc. ("DWR") and other
broker-dealer affiliates of InterCapital. In addition, the Fund may incur
brokerage commissions on transactions conducted through DWR and other brokers
and dealers that are affiliates of InterCapital.
    
 
    Although the Fund does not intend to engage in substantial short-term
trading, it may sell portfolio securities without regard to the length of time
that they have been held, in order to take advantage of new investment
opportunities or yield differentials, or because the Fund desires to preserve
gains or limit losses due to changing economic conditions, interest rate trends,
or the financial condition of the issuer. The Fund's portfolio turnover rate for
the fiscal year ended August 31, 1996 was 49%. The Fund will incur underwriting
discount costs (on underwritten securities) and brokerage costs commensurate
with its portfolio turnover rate. Short term gains and losses may result from
such portfolio transactions. See "Dividends, Distributions and Taxes" for a
discussion of the tax implications of the Fund's trading policy.
 
    Except as otherwise noted, all investment policies and practices discussed
above are not fundamental policies of the Fund and, as such may be changed
without shareholder approval.
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    The investment restrictions listed below are among the restrictions that
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.
 
    The Fund may not:
 
   1. Acquire common stocks in excess of 20% of its total assets.
 
   2. Invest more than 5% of its total assets in the securities of any one
issuer (other than obligations of, or guaranteed by, the United States
Government, its agencies or instrumentalities).
 
   3. Purchase more than 10% of the voting securities, or more than 10% of any
class of securities, of any issuer. For purposes of this restriction, all
outstanding debt securities of an issuer are considered as one class and all
preferred stocks of an issuer are considered as one class.
 
   4. Invest more than 25% of its total assets in securities of issuers in any
one industry. For purposes of this restriction, gas, electric, water and
telephone utilities will each be treated as being a separate industry. This
restriction does not apply to obligations issued or guaranteed by the United
States Government or its agencies or instrumentalities.
 
   5. Invest more than 5% of its total assets in securities of companies 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.
 
                                       13
<PAGE>
   
    Notwithstanding any other investment policy or restriction, the Fund may
seek to achieve its investment objectives by investing all or substantially all
of its assets in another investment company having substantially the same
investment objectives and policies as the Fund.
    
 
PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
   
GENERAL
    
 
   
    The Fund offers each class of its shares for sale to the public on a
continuous basis. Pursuant to a Distribution Agreement between the Fund and Dean
Witter Distributors Inc. (the "Distributor"), an affiliate of the Investment
Manager, shares of the Fund are distributed by the Distributor and offered by
DWR and other dealers who have entered into 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 High Yield Securities Inc., directly to
Dean Witter Trust Company (the "Transfer Agent") at P.O. Box 1040, Jersey City,
N.J. 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-SM-, an automatic purchase plan (see "Shareholder
Services"), is $100, provided that the schedule of automatic investments will
result in investments totalling at least $1,000 within the first twelve months.
In the case of purchases made pursuant to Systematic Payroll Deduction
    
 
                                       14
<PAGE>
   
plans (including Individual Retirement plans), the Fund, in its discretion, may
accept such Purchases without regard to any minimum amounts which would
otherwise be required if the Fund has reason to believe that additional
purchases will increase the amount of the purchase of shares 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 are sold through the Distributor on a normal three business day
settlement basis; that is, payment is due on the third business day (settlement
date) after the order is placed with the Distributor. Since DWR and other
Selected Broker-Dealers forward investors' funds on settlement date, they will
benefit from the temporary use of the funds if payment is made prior thereto. As
noted above, orders placed directly with the Transfer Agent must be accompanied
by payment. Investors will be entitled to receive income dividends and capital
gains distributions if their order is received by the close of business on the
day prior to the record date for such dividends and distributions. Sales
personnel of a Selected Broker-Dealer are compensated for selling shares of the
Fund by the Distributor or any of its affiliates and/or the Selected
Broker-Dealer. In addition, some sales personnel of the Selected Broker-Dealer
will receive various types of non-cash compensation as special sales incentives,
including trips, educational and/or business seminars and merchandise. The Fund
and the Distributor reserve the right to reject any purchase order.
    
 
   
    ANALOGOUS DEAN WITTER FUNDS.  The Distributor and the Investment Manager
serve in the same capacities for Dean Witter High Income Securities, an open-end
investment company with investment objectives and policies similar to those of
the Fund. Shares of Dean Witter High Income Securities are offered to the public
at net asset value, with a CDSC assessed upon redemptions within five years of
purchase, as well as an annual Rule 12b-1 distribution fee. The Classes of the
Fund and Dean Witter High Income Securities have differing fees and expenses,
which will affect performance. Investors who would like to receive a prospectus
for Dean Witter High Income Securities should call the telephone numbers listed
on the front cover of this Prospectus, or may call their account executive for
additional information.
    
 
   
    The Board of Directors of the Fund and the Board of Trustees of Dean Witter
High Income Securities have approved a reorganization plan whereby Dean Witter
High Income Securities would be merged into the Fund. This plan is subject to
the consent of the Dean Witter High Income Securities shareholders. If approved,
the Funds' assets would be combined and Dean Witter High Income Securities
shareholders would become shareholders of the Fund, receiving Class B shares of
the Fund equal to the value of their holdings in Dean Witter High Income
Securities. A proxy statement formally detailing the proposal will be
distributed to Dean Witter High Income Securities shareholders in August 1997.
    
 
   
ALTERNATIVE PURCHASE ARRANGEMENTS
    
 
   
    The Fund offers several Classes of shares to investors designed to provide
them with the flexibility of selecting an investment best suited to their needs.
The general public is offered three Classes of shares: Class A shares, Class B
shares and Class C shares, which differ principally in terms of sales charges
and rate of expenses to which they are subject. A fourth Class of shares, Class
D shares, is offered only to limited categories of investors (see "No Load
Alternative--Class D Shares" below).
    
 
   
    Each Class A, Class B, Class C or Class D share of the Fund represents an
identical interest in the investment portfolio of the Fund except that Class A,
Class B and Class C shares bear the expenses of the ongoing shareholder service
fees, Class B and Class C shares bear the expenses of
    
 
                                       15
<PAGE>
   
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 4.25%. The initial sales charge is reduced for certain
purchases. Investments of $1 million or more (and investments by certain other
limited categories of investors) are not subject to any sales charges at the
time of purchase but are subject to a CDSC of 1.0% on redemptions made within
one year after purchase, except for certain specific circumstances. Class A
shares are also subject to a 12b-1 fee of up to 0.25% of the average daily net
assets of the Class. See "Initial Sales Charge Alternative--Class A Shares."
    
 
   
    CLASS B SHARES.  Class B shares are offered at net asset value with no
initial sales charge but are subject to a CDSC (scaled down from 5.0% to 1.0%)
if redeemed within six years of purchase. (Class B shares purchased by certain
qualified employer-sponsored benefit plans are subject to a CDSC scaled down
from 2.0% to 1.0% if redeemed within three years after purchase.) This CDSC may
be waived for certain redemptions. Class B shares are also subject to an annual
12b-1 fee of 0.75% of the
    
 
   
average daily net assets of Class B. The Class B shares' distribution fee will
cause that Class to have higher expenses and pay lower dividends than Class A or
Class D shares.
    
 
   
    After approximately ten (10) years, Class B shares will convert
automatically to Class A shares of the Fund, based on the relative net asset
values of the shares of the two Classes on the conversion date. In addition, a
certain portion of Class B shares that have been acquired through the
reinvestment of dividends and distributions will be converted at that time. See
"Contingent Deferred Sales Charge Alternative--Class B Shares."
    
 
   
    CLASS C SHARES.  Class C shares are sold at net asset value with no initial
sales charge but are subject to a CDSC of 1.0% on redemptions made within one
year after purchase. This CDSC may be waived for certain redemptions. They are
subject to an annual 12b-1 fee of up to 0.85% of the average daily net assets of
the Class C shares. The Class C shares' distribution fee may cause that Class to
have higher expenses and pay lower dividends than Class A or Class D shares. See
"Level Load Alternative--Class C Shares."
    
 
   
    CLASS D SHARES.  Class D shares are available only to limited categories of
investors (see "No Load Alternative--Class D Shares" below). Class D shares are
sold at net asset value with no initial sales charge or CDSC. They are not
subject to any 12b-1 fees. See "No Load Alternative--Class D Shares."
    
 
   
    SELECTING A PARTICULAR CLASS.  In deciding which Class of Fund shares to
purchase, investors should consider the following factors, as well as any other
relevant facts and circumstances:
    
 
   
    The decision as to which Class of shares is more beneficial to an investor
depends on the amount and intended length of his or her investment. Investors
who prefer an initial sales charge alternative may elect to purchase Class A
shares. Investors qualifying for significantly reduced or, in
    
 
                                       16
<PAGE>
   
the case of purchases of $1 million or more, no initial sales charges may find
Class A shares particularly attractive because similar sales charge reductions
are not available with respect to Class B or Class C shares. Moreover, Class A
shares are subject to lower ongoing expenses than are Class B or Class C shares
over the term of the investment. As an alternative, Class B and Class C shares
are sold without any initial sales charge so the entire purchase price is
immediately invested in the Fund.
    
 
   
Any investment return on these additional investment amounts may partially or
wholly offset the higher annual expenses of these Classes. Because the Fund's
future return cannot be predicted, however, there can be no assurance that this
would be the case.
    
 
   
    Finally, investors should consider the effect of the CDSC period and any
conversion rights of the Classes in the context of their own investment time
frame. For example, although Class C shares are subject to a significantly lower
CDSC upon redemptions, they do not, unlike Class B shares, convert into Class A
shares after approximately ten years, and, therefore, are subject to an ongoing
12b-1 fee of 0.85% (rather than the 0.25% fee applicable to Class A shares) for
an indefinite period of time. Thus, Class B shares may be more attractive than
Class C shares to investors with longer term investment outlooks. Other
investors, however, may elect to purchase Class C shares if, for example, they
determine that they 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:

INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES
    
 
   
    Class A shares are sold at net asset value plus an initial sales charge. In
some cases, reduced sales charges may be available, as described below.
Investments of $1 million or more (and investments by certain other limited
categories of investors) are not subject to any sales charges at

the time of purchase but are subject to a CDSC of 1.0% on redemptions made
within one year after purchase (calculated from the last day of the month in
which the shares were purchased), except for certain specific circumstances. The
CDSC will be assessed on an amount equal to the lesser of the current market
value or the cost of the shares being redeemed. The CDSC will not be imposed (i)
in the circumstances set forth below in the section "Contingent Deferred Sales
Charge Alternative--Class B Shares--CDSC Waivers," except that the references to
six years in the first paragraph of that section shall mean one year in the case
of Class A shares, and (ii) in the circumstances identified in the section
"Additional Net Asset Value Purchase Options" below. Class A shares are also
subject to an annual 12b-1 fee of up to 0.25% of the average daily net assets of
the Class.
    
 
   
    The offering price of Class A shares will be the net asset value per share
next determined following receipt of an order (see "Determination of Net Asset
Value" below), plus a sales charge (expressed as a percentage of the offering
price) on a single transaction as shown in the following table:

    Upon notice to all Selected Broker-Dealers, the Distributor may reallow up
to the full applicable sales charge as shown in the above schedule during
periods specified in such notice. During periods when 90% or more of the sales
charge is reallowed, such Selected Broker-Dealers may be deemed to be
underwriters as that term is defined in the Securities Act of 1933.
    
 
   
    The above schedule of sales charges is applicable to purchases in a single
transaction by, among others: (a) an individual; (b) an individual, his or her
spouse and their children under the age of 21 purchasing shares for his, her or
their own accounts; (c) a trustee or other fiduciary purchasing shares for a
single trust estate or a single fiduciary account; (d) a pension, profit-sharing
or other employee benefit plan qualified or non-qualified under Section 401 of
the Internal Revenue Code; (e) tax-exempt organizations enumerated in Section
501(c)(3) or (13) of the Internal Revenue Code; (f) employee benefit plans
qualified under Section 401 of the Internal Revenue Code of a single employer or
of employers who are "affiliated persons" of each other within the meaning of
Section 2(a)(3)(c) of the Act; and for investments in Individual Retirement
Accounts of employees of a single employer through Systematic Payroll Deduction
plans; or (g) any other organized group of persons, whether incorporated or not,
provided the organization has been in existence for at least six months and has
some purpose other than the purchase of redeemable securities of a registered
investment company at a discount.
    
 
   
    COMBINED PURCHASE PRIVILEGE.  Investors may have the benefit of reduced
sales charges in accordance with the above schedule by combining purchases of
Class A shares of the Fund in single transactions with the purchase of Class A
shares of other Dean Witter Multi-Class Funds and shares of FSC Funds. The sales
charge payable on the purchase of the Class A shares of the Fund, the Class A
shares of the other Dean Witter Multi-Class Funds and the shares of the FSC
Funds will be at their respective rates applicable to the total amount of the
combined concurrent purchases of such shares.
    
 
   
    RIGHT OF ACCUMULATION.  The above persons and entities may benefit from a
reduction of the sales charges in accordance with the above schedule if the
cumulative net asset value of Class A shares purchased in a single transaction,
together with shares of the Fund and other Dean Witter Funds previously
purchased at a price including a
    
 
                                       18
<PAGE>
   
front-end sales charge (including shares of the Fund and other Dean Witter Funds
acquired in exchange for those shares, and including in each case shares
acquired through reinvestment of dividends and distributions), which are held at
the time of such transaction, amounts to $25,000 or more. If such investor has a
cumulative net asset value of shares of FSC Funds and Class A and Class D shares
equal to at least $5 million, such investor is eligible to purchase Class D
shares subject to the $1,000 minimum initial investment requirement of that
Class of the Fund. See "No Load Alternative-- Class D Shares" below.
    
 
   
    The Distributor must be notified by DWR or a Selected Broker-Dealer or the
shareholder at the time a purchase order is placed that the purchase qualifies
for the reduced charge under the Right of Accumulation. Similar notification
must be made in writing by the dealer or shareholder when such an order is
placed by mail. The reduced sales charge will not be granted if: (a) such
notification is not furnished at the time of the order; or (b) a review of the
records of the Selected Broker-Dealer or the Transfer Agent fails to confirm the
investor's represented holdings.
    
 
   
    LETTER OF INTENT.  The foregoing schedule of reduced sales charges will also
be available to investors who enter into a written Letter of Intent providing
for the purchase, within a thirteen-month period, of Class A shares of the Fund
from DWR or other Selected Broker-Dealers. The cost of Class A shares of the
Fund or shares of other Dean Witter Funds which were previously purchased at a
price including a front-end sales charge during the 90-day period prior to the
date of receipt by the Distributor of the Letter of Intent, or of Class A shares
of the Fund or shares of other Dean Witter Funds acquired in exchange for shares
of such funds purchased during such period at a price including a front-end
sales charge, which are still owned by the shareholder, may also be included in
determining the applicable reduction.
    
 
   
    ADDITIONAL NET ASSET VALUE PURCHASE OPTIONS. In addition to investments of
$1 million or more, Class A shares also may be purchased at net asset value by
the following:
    
 
   
   (1) trusts for which Dean Witter Trust Company ("DWTC") or Dean Witter Trust
FSB ("DWTFSB") (each of which is an affiliate of the Investment Manager)
provides discretionary trustee services;
    
 
   
   (2) persons participating in a fee-based program approved by the Distributor,
pursuant to which such persons pay an asset based fee for services in the nature
of investment advisory or administrative services (such investments are subject
to all of the terms and conditions of such programs, which may include
termination fees and restrictions on transferability of Fund shares);
    
 
   
   (3) retirement plans qualified under Section 401(k) of the Internal Revenue
Code ("401(k) plans") and other employer-sponsored plans qualified under Section
401(a) of the Internal Revenue Code with at least 200 eligible employees and for
which DWTC or DWTFSB serves as Trustee or the 401(k) Support Services Group of
DWR serves as recordkeeper;
    
 
   
   (4) 401(k) plans and other employer-sponsored plans qualified under Section
401(a) of the Internal Revenue Code for which DWTC or DWTFSB serves as Trustee
or the 401(k) Support Services Group of DWR serves as recordkeeper whose Class B
shares have converted to Class A shares, regardless of the plan's asset size or
number of eligible employees;
    
 
   
   (5) investors who are clients of a Dean Witter account executive who joined
Dean Witter from another investment firm within six months prior to the date of
purchase of Fund shares by such investors, if the shares are being purchased
with the proceeds from a redemption of shares of an open-end proprietary mutual
fund of the account executive's previous firm which imposed either a front-end
or deferred sales charge, provided such purchase was made within sixty days
after the redemption and the proceeds of the redemption had been maintained in
the interim in cash or a money market fund; and
    
 
   
   (6) other categories of investors, at the discretion of the Board, as
disclosed in the then current prospectus of the Fund.
    
 
                                       19

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

DWR or another Selected Broker-Dealer or consult the Statement of Additional
Information.
    
 
   
CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE--CLASS B SHARES
    
 
   
    Class B shares are sold at net asset value next determined without an
initial sales charge so that the full amount of an investor's purchase payment
may be immediately invested in the Fund. A CDSC, however, will be imposed on
most Class B shares redeemed within six years after purchase. The CDSC will be
imposed on any redemption of shares if after such redemption the aggregate
current value of a Class B account with the Fund falls below the aggregate
amount of the investor's purchase payments for Class B shares made during the
six years (or, in the case of shares held by certain employer-sponsored benefit
plans, three years) preceding the redemption. In addition, Class B shares are
subject to an annual 12b-1 fee of 0.75% of the 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 paragraph above), 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
    
 
                                       20
<PAGE>
   
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 DWTC or DWTFSB serves as Trustee or the 401(k)
Support Services Group of DWR serves as recordkeeper ("Eligible Plan"), provided
that either:  (a) the plan continues to be an Eligible Plan after the
redemption; or  (b) the redemption is in connection with the complete
termination of the plan involving the distribution of all plan assets to
participants.
    
 
   
    With reference to (1) above, for the purpose of determining disability, the
Distributor utilizes the definition of disability contained in Section 72(m)(7)
of the Internal Revenue Code, which relates to the inability to engage in
gainful employment. With reference to (2) above, the term "distribution" does
not encompass a direct transfer of IRA, 403(b) Custodial Account or retirement
plan assets to a successor custodian or trustee. All waivers will be granted
only following receipt by the Distributor of confirmation of the shareholder's
entitlement.
    
 
   
    CONVERSION TO CLASS A SHARES.  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. The
conversion of shares will take place in the month following the tenth
anniversary of the purchase. There will also be converted at that time such
proportion of Class B shares acquired through automatic reinvestment of
dividends and distributions owned by the shareholder as the total number of his
or her Class B shares converting at the time bears to the total number of
outstanding Class B shares purchased and owned by the shareholder. In the case
of Class B shares held by a 401(k) plan or other employer-sponsored plan
qualified under Section 401(a) of the Internal Revenue Code and for which DWTC
or DWTFSB serves as Trustee or the 401(k) Support Services Group of DWR serves
as recordkeeper, the plan is treated as a single investor and all Class B shares
will convert to Class A shares on the conversion date of the first shares of a
Dean Witter Multi-Class Fund purchased by that plan. In the case of Class B
shares previously exchanged for shares of an "Exchange Fund" (see "Shareholder
Services--Exchange Privilege"), the period of time the shares were held in the
Exchange Fund (calculated from the last day of the month in which the Exchange
Fund shares were acquired) is excluded from the holding period for conversion.
If those shares are subsequently re-exchanged for Class B shares of a Dean
Witter Multi-Class Fund, the holding period resumes on the last day of the month
in which Class B shares are reacquired.
    
 
                                       21
<PAGE>
   
    If a shareholder has received share certificates for Class B shares, such
certificates must be delivered to the Transfer Agent at least one week prior to
the date for conversion. Class B shares evidenced by share certificates that are
not received by the Transfer Agent at least one week prior to any conversion
date will be converted into Class A shares on the next scheduled conversion date
after such certificates are received.
    
 
   
    Effectiveness of the conversion feature is subject to the continuing
availability of a ruling of the Internal Revenue Service or an opinion of
counsel that (i) the conversion of shares does not constitute a taxable event
under the Internal Revenue Code, (ii) Class A shares received on conversion will
have a basis equal to the shareholder's basis in the converted Class B shares
immediately prior to the conversion, and (iii) Class A shares received on
conversion will have a holding period that includes the holding period of the
converted Class B shares. The conversion feature may be suspended if the ruling
or opinion is no longer available. In such event, Class B shares would continue
to be subject to Class B 12b-1 fees.
    
 
   
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 0.85% of the average daily net assets of
the Class. Unlike Class B shares, Class C shares have no conversion feature and,
accordingly, an investor that purchases Class C shares will be subject to 12b-1
fees applicable to Class C shares for an indefinite period subject to annual
approval by the Fund's Board of Trustees and regulatory limitations.
    
 
   
NO LOAD ALTERNATIVE--CLASS D SHARES
    
 
   
    Class D shares are offered without any sales charge on purchase or
redemption and without any 12b-1 fee. Class D shares are offered only to
investors meeting an initial investment minimum of $5 million and the following
categories of investors: (i) investors participating in the InterCapital mutual
fund asset allocation program pursuant to which such persons pay an asset based
fee; (ii) persons participating in a fee-based program approved by the
Distributor, pursuant to which such persons pay an asset based fee for services
in the nature of investment advisory or administrative services (subject to all
of the terms and conditions of such programs, which may include termination fees
and restrictions on transferability of Fund shares); (iii) 401(k) plans
established by DWR and SPS Transaction Services, Inc. (an affiliate of DWR) for
their employees; (iv) certain Unit Investment Trusts sponsored by DWR; (v)
certain other open-end investment companies whose shares are distributed by the
Distributor; and (vi) other categories of investors, at the discretion of the
Board, as disclosed in the then current prospectus of the Fund. All shares of
the Fund held prior to July 28, 1997 have been designated Class D shares.
Additional investments in Class D shares by shareholders holding such shares may
only be made if those shareholders are otherwise eligible to purchase Class D
shares. However, shareholders holding such shares will receive the benefit of
the value of such shares towards reduced sales charges on purchases of Class A
shares pursuant to the Fund's "Right of Accumulation" (see "Initial Sales Charge
Alternative--Class A Shares--Right of Accumulation"). 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
    
 
                                       22
<PAGE>
   
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
    
 
   
    Effective July 28, 1997, the Fund has adopted a Plan of Distribution
pursuant to Rule 12b-1 under the Act with respect to the distribution of Class
A, Class B and Class C shares of the Fund. In the case of Class A and Class C
shares, the Plan provides that the Fund will reimburse the Distributor and
others for the expenses of certain activities and services incurred by them
specifically on behalf of those shares. Reimbursements for these expenses will
be made in monthly payments by the Fund to the Distributor, which will in no
event exceed amounts equal to payments at the annual rates of 0.25% and 0.85% of
the average daily net assets of Class A and Class C, respectively. In the case
of Class B shares, the Plan provides that the Fund will pay the Distributor a
fee, which is accrued daily and paid monthly, at the annual rate of 0.75% of the
average daily net assets of Class B. The fee is treated by the Fund as an
expense in the year it is accrued. In the case of Class A shares, the entire
amount of the fee currently represents a service fee within the meaning of the
NASD guidelines. In the case of Class B and Class C shares, a portion of the fee
payable pursuant to the Plan, equal to 0.20% and 0.25% of the average daily net
assets of each of these Classes, respectively, is currently characterized as a
service fee. A service fee is a payment made for personal service and/or the
maintenance of shareholder accounts.
    
 
   
    Additional amounts paid under the Plan in the case of Class B and Class C
shares are paid to the Distributor for services provided and the expenses borne
by the Distributor and others in the distribution of the shares of those
Classes, including the payment of commissions for sales of the shares of those
Classes and incentive compensation to and expenses of DWR's account executives
and others who engage in or support distribution of shares or who service
shareholder accounts, including overhead and telephone expenses; printing and
distribution of prospectuses and reports used in connection with the offering of
the Fund's shares to other than current shareholders; and preparation, printing
and distribution of sales literature and advertising materials. In addition, the
Distributor may utilize fees paid pursuant to the Plan in the case of Class B
shares to compensate DWR and other Selected Broker-Dealers for their opportunity
costs in advancing such amounts, which compensation would be in the form of a
carrying charge on any unreimbursed expenses.
    
 
   
    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. 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
    
 
                                       23
<PAGE>
   
CDSCs, may or may not be recovered through future distribution fees or CDSCs.
    
 
   
    In the case of Class A and Class C shares, expenses incurred pursuant to the
Plan in any calendar year in excess of 0.25% or 0.85% of the average daily net
assets of Class A or Class C, respectively, will not be reimbursed by the Fund
through payments in any subsequent year, except that expenses representing a
gross sales commission credited to account executives at the time of sale may be
reimbursed in the subsequent calendar year. No interest or other financing
charges will be incurred on any Class A or Class C distribution expenses
incurred by the Distributor under the Plan or on any unreimbursed expenses due
to the Distributor pursuant to the Plan.
    
 
DETERMINATION OF NET ASSET VALUE
 
   
    The net asset value per share is determined once daily at 4:00 p.m., New
York time on each day that the New York Stock Exchange is open (or, on days when
the New York Stock Exchange closes prior to 4:00 p.m., at such earlier time), by
taking the net assets of the Fund, dividing by the number of shares outstanding
and adjusting to the nearest cent. The assets belonging to the Class A, Class B,
Class C and Class D shares will be invested together in a single portfolio. The
net asset value of each Class, however, will be determined separately by
subtracting each Class's accrued expenses and liabilities. The net asset value
per share will not be determined on Good Friday and on such other federal and
non-federal holidays as are observed by the New York Stock Exchange.
    
 
   
    In the calculation of the Fund's net asset value: (1) an equity portfolio
security listed or traded on the New York or American Stock Exchange or other
domestic or foreign exchange is valued at its latest sale price on that exchange
prior to the time assets are valued; (if there were no sales that day, the
security is valued at the latest bid price); and (2) all other portfolio
securities for which over-the-counter market quotations are readily available
are valued at the latest bid price. When market quotations are not readily
available, including circumstances under which it is determined by the
Investment Manager that sale or bid prices are not reflective of a security's
market value, portfolio securities are valued at their fair value as determined
in good faith under procedures established by and under the general supervision
of the Fund's Board of Directors (valuation of 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).
    
 
    Certain of the Fund's portfolio securities may be valued by an outside
pricing service approved by the Fund's Directors. The pricing service may
utilize a matrix system incorporating security quality, maturity and coupon as
the evaluation model parameters, and/or research evaluations by its staff,
including review of broker-dealer market price quotations, in determining what
it believes is the fair valuation of the portfolio securities valued by such
pricing service.
 
    Municipal securities will be valued for the Fund by an outside computer
matrix pricing service approved by the Board of Directors. Periodically, the
Investment Manager and the Board of Directors review the continued
appropriateness of the prices obtained through the service.
 
    Short-term debt securities with remaining maturities of 60 days or less at
the time of purchase are valued at amortized cost, unless the Board determines
such does not reflect the securities' fair value, in which case these securities
will be valued at their fair market value as determined by the Board of
Directors. Other short-term debt securities will be valued on a marked-to-market
basis until such time as they reach a maturity of 60 days, whereupon they will
be valued at amortized cost using their value on the 61st day unless the
Directors determine such does not reflect the securities' market value, in which
case these securities will be valued at their fair market value as determined by
the Board of Directors. Listed options on debt securities are
val-
 
                                       24
<PAGE>
ued at the latest sale price on the exchange on which they are listed unless no
sales of such options have taken place that day, in which case, they will be
valued at the mean between their closing bid and asked prices. Unlisted options
on debt securities and all options on equity securities are valued at the mean
between their latest bid and asked price. Futures are valued at the latest sale
price on the commodities exchange on which they trade unless the Directors
determine that such price does not reflect their market value, in which case
they will be valued at their fair value as determined by the Board of Directors.
All other securities and other assets are valued at their fair value as
determined in good faith under procedures established by and under the
supervision of the Board of Directors.
 
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 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-SM-.  Shareholders may subscribe to EasyInvest, an automatic
purchase plan which provides for any amount from $100 to $5,000 to be
transferred automatically from a checking or savings account or following
redemption of shares of a Dean Witter money market fund, on a semi-monthly,
monthly or quarterly basis, to the Fund's Transfer Agent for investment in
shares of the Fund (see "Purchase of Fund Shares" and "Redemptions and
Repurchases--Involuntary Redemption").
    
 
   
    SYSTEMATIC WITHDRAWAL PLAN.  A 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 plan
provides for monthly or quarterly (March, June, September, 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 (net of any applicable
CDSC) to the shareholder will be the designated monthly or quarterly amount.
Withdrawal plan payments should not be considered as dividends, yields or
income. If periodic withdrawal plan payments continuously exceed net investment
income and net capital gains, the shareholder's original investment will be
correspondingly reduced and ultimately exhausted. Each withdrawal constitutes a
redemption of shares and any gain or loss realized must be recognized for
federal income tax purposes.
    
 
   
    Shareholders should contact their DWR or other Selected Broker-Dealer
account executive or the Transfer Agent for further information about any of the
above services.
    
 
   
    TAX-SHELTERED RETIREMENT PLANS.  Retirement plans are available through the
Investment Manager for use by corporations, the self-employed, Individual
Retirement Accounts and Custodial Accounts
    
 
                                       25
<PAGE>
under Section 403(b)(7) of the Internal Revenue Code. Adoption of such plans
should be on advice of legal counsel or tax adviser.
 
    For further information regarding plan administration, custodial fees and
other details, investors should contact the Fund.
 
   
EXCHANGE PRIVILEGE
    
 
   
    Shares of each Class may be exchanged for shares of the same Class of any
other Dean Witter Multi-Class Fund without the imposition of any exchange fee.
Shares may also be exchanged for shares of the following funds: Dean Witter
Short-Term U.S. Treasury Trust, Dean Witter Limited Term Municipal Trust, Dean
Witter Short-Term Bond Fund, Dean Witter Intermediate Term U.S. Treasury Trust
and five Dean Witter funds which are money market funds (the "Exchange Funds").
Class A shares may also be exchanged for shares of Dean Witter Multi-State
Municipal Series Trust and Dean Witter Hawaii Municipal Trust, which are Dean
Witter Funds sold with a front-end sales charge ("FSC Funds"). Class B shares
may also be exchanged for shares of Dean Witter Global Short-Term Income Fund
Inc., Dean Witter High Income Securities and Dean Witter National Municipal
Trust, which are Dean Witter Funds offered with a CDSC ("CDSC Funds"). Exchanges
may be made after the shares of the Fund acquired by purchase (not by exchange
or dividend reinvestment) have been held for thirty days. There is no holding
period for exchanges of shares acquired by exchange or dividend reinvestment.
    
 
   
    An exchange to another Dean Witter Multi-Class Fund, any FSC Fund, any CDSC
Fund or any Exchange Fund that is not a money market fund is on the basis of the
next calculated net asset value per share of each fund after the exchange order
is received. When exchanging into a money market fund from the Fund, shares of
the Fund are redeemed out of the Fund at their next calculated net asset value
and the proceeds of the redemption are used to purchase shares of the money
market fund at their net asset value determined the following business day.
Subsequent exchanges between any of the money market funds and any of the Dean
Witter Multi-Class Funds, FSC Funds or CDSC Funds or any Exchange Fund that is
not a money market fund can be effected on the same basis.
    
 
   
    No CDSC is imposed at the time of any exchange of shares, although any
applicable CDSC will be imposed upon ultimate redemption. During the period of
time the shareholder remains in an Exchange Fund (calculated from the last day
of the month in which the Exchange Fund shares were acquired), the holding
period (for the purpose of determining the rate of the CDSC) is frozen. If those
shares are subsequently re-exchanged for shares of a Dean Witter Multi-Class
Fund or shares of a CDSC Fund, the holding period previously frozen when the
first exchange was made resumes on the last day of the month in which shares of
a Dean Witter Multi-Class Fund or shares of a CDSC Fund are reacquired. Thus,
the CDSC is based upon the time (calculated as described above) the shareholder
was invested in shares of a Dean Witter Multi-Class Fund or in shares of a CDSC
Fund (see "Purchase of Fund Shares"). In the case of exchanges of Class A shares
which are subject to a CDSC, the holding period also includes the time
(calculated as described above) the shareholder was invested in shares of a FSC
Fund. However, in the case of shares exchanged into an Exchange Fund on or after
April 23, 1990, upon a redemption of shares which results in a CDSC being
imposed, a credit (not to exceed the amount of the CDSC) will be given in an
amount equal to the Exchange Fund 12b-1 distribution fees incurred on or after
that date which are attributable to those shares. (Exchange Fund 12b-1
distribution fees are described in the prospectuses for those funds.) Class B
shares of the Fund acquired in exchange for Class B shares of another Dean
Witter Multi-Class Fund or shares of a CDSC Fund having a different CDSC
schedule than that of this Fund will be subject to the higher CDSC
    
 
                                       26
<PAGE>
   
schedule, even if such shares are subsequently re-exchanged for shares of the
fund with the lower CDSC schedule.
    
 
   
    ADDITIONAL INFORMATION REGARDING EXCHANGES. Purchases and exchanges should
be made for investment purposes only. A pattern of frequent exchanges may be
deemed by the Investment Manager to be abusive and contrary to the best
interests of the Fund's other shareholders and, at the Investment Manager's
discretion, may be limited by the Fund's refusal to accept additional purchases
and/ or exchanges from the investor. Although the Fund does not have any
specific definition of what constitutes a pattern of frequent exchanges, and
will consider all relevant factors in determining whether a particular situation
is abusive and contrary to the best interests of the Fund and its other
shareholders, investors should be aware that the Fund and each of the other Dean
Witter Funds may in their discretion limit or otherwise restrict the number of
times this Exchange Privilege may be exercised by any investor. Any such
restriction will be made by the Fund on a prospective basis only, upon notice to
the shareholder not later than ten days following such shareholder's most recent
exchange. Also, the Exchange Privilege may be terminated or revised at any time
by the Fund and/or any of such Dean Witter Funds for which shares of the Fund
have been exchanged, upon such notice as may be required by applicable
regulatory agencies. Shareholders maintaining margin accounts with DWR or
another Selected Broker-Dealer are referred to their account executive regarding
restrictions on exchange of shares of the Fund pledged in the margin account.
    
 
   
    The current prospectus for each fund describes its investment objective(s)
and policies, and shareholders should obtain a copy and examine it carefully
before investing. Exchanges are subject to the minimum investment requirement of
each Class of shares and any other conditions imposed by each fund. In the case
of a shareholder holding a share certificate or certificates, no exchanges may
be made until all applicable share certificates have been received by the
Transfer Agent and deposited in the shareholder's account. An exchange will be
treated for federal income tax purposes the same as a repurchase or redemption
of shares, on which the shareholder may realize a capital gain or loss. However,
the ability to deduct capital losses on an exchange may be limited in situations
where there is an exchange of shares within ninety days after the shares are
purchased. The Exchange Privilege is only available in states where an exchange
may legally be made.
    
 
    If DWR or another Selected Broker-Dealer is the current dealer of record and
its account numbers are part of the account information, shareholders may
initiate an exchange of shares of the Fund for shares of any of the Dean Witter
Funds (for which the Exchange Privilege is available) pursuant to this Exchange
Privilege by contacting their DWR or other Selected Broker-Dealer account
executive (no Exchange Privilege Authorization Form is required). Other
shareholders (and those shareholders who are clients of DWR or other Selected
Broker-Dealer but who wish to make exchanges directly by telephoning the
Transfer Agent) must complete and forward to the Transfer Agent an Exchange
Privilege Authorization form, copies of which may be obtained from the Transfer
Agent, to initiate an exchange. If the Authorization Form is used, exchanges may
be made in writing or by contacting the Transfer Agent at (800) 869-NEWS
(toll-free).
 
    The Fund will employ reasonable procedures to confirm that exchange
instructions communicated over the telephone are genuine. Such procedures may
include requiring various forms of personal identification such as name, mailing
address, social security or other tax identification number and DWR or other
Selected Broker-Dealer account number (if any). Telephone instructions may also
be recorded. If such procedures are not employed, the Fund may be liable for any
losses due to unauthorized or fraudulent instructions.
 
                                       27
<PAGE>
    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 Form and who is unable to reach the Fund
by telephone should contact his or her DWR or other Selected Broker-Dealer
account executive, if appropriate, or make a written exchange request.
Shareholders are advised that during periods of drastic economic or market
changes, it is possible that the telephone exchange procedures may be difficult
to implement, although this has not been the experience of the Dean Witter Funds
in the past.
 
    Shareholders should contact their DWR or other Selected Broker-Dealer
account executive or the Transfer Agent for further information about the
Exchange Privilege.
 
REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 
   
    REDEMPTION.  Shares of each Class of the Fund can be redeemed for cash at
any time at the current 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 stock certificate, a written request for redemption is required. If
certificates are held by the shareholder, the shares may be redeemed by
surrendering the certificates with a written request for redemption along with
any additional information requested by the Transfer Agent.
    
 
   
    REPURCHASE.  DWR and other Selected Broker-Dealers are authorized to
repurchase, as agent for the Fund, shares represented by a stock certificate
which is delivered to any of their offices. Shares held in a shareholder's
account without a stock certificate may also be repurchased by DWR and other
Selected Broker-Dealers upon the telephonic request of the shareholder. The
repurchase price is the net asset value next determined (see "Purchase of Fund
Shares") after such repurchase order is received by DWR or other Selected
Broker-Dealer reduced by any applicable CDSC.
    
 
   
    The CDSC, if any, will be the only fee imposed by the Fund, the Distributor,
DWR or other Selected Broker-Dealers. The offer by DWR and other Selected
Broker-Dealers to repurchase shares may be suspended without notice by them at
any time. In that event, shareholders may redeem their shares through the Fund's
Transfer Agent as set forth above under "Redemption."
    
 
   
    PAYMENT FOR SHARES REDEEMED OR REPURCHASED.  Payment for shares presented
for repurchase or redemption will be made by check within seven days after
receipt by the Transfer Agent of the certificate and/or written request in good
order. Such payment may be postponed or the right of redemption suspended at
times 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 and other Selected Broker Dealers 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 their net asset value next determined after a
    
rein-
 
                                       28
<PAGE>
   
statement 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
repurchase or redemption.
    
 
   
    INVOLUNTARY REDEMPTION.  The Fund reserves the right, on sixty days' notice,
to redeem, at their net asset value, the shares of any shareholder (other than
shares held in an Individual Retirement Account or custodial account under
Section 403(b)(7) of the Internal Revenue Code) whose shares due to redemptions
by the shareholder have a value of less than $100, or such lesser amount as
    
 
   
may be fixed by the Board of Directors or, in the case of an account opened
through EasyInvest, if after twelve months the shareholder has invested less
than $1,000 in the account. However, before the Fund redeems such shares and
sends the proceeds to the shareholder, it will notify the shareholder that the
value of the shares is less than the applicable amount and allow the shareholder
sixty days in which to make an additional investment in an amount which will
increase the value of the account to at least the applicable amount or more
before the redemption is processed. No CDSC will be imposed on any involuntary
redemption.
    
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
   
    DIVIDENDS AND DISTRIBUTIONS.  The Fund declares dividends separately for
each Class of shares and intends to declare and pay monthly income dividends and
to distribute net short-term and net long-term capital gains, if any, at least
once each year. The Fund may, however, determine either to distribute or to
retain all or part of any long-term capital gains in any year for reinvestment.
    
 
   
    All dividends and capital gains distributions will be paid in additional
shares of the same Class and automatically credited to the shareholder's account
without issuance of a stock 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 capital gains to shareholders and otherwise continue to qualify
as a regulated investment company under Subchapter M of the Internal Revenue
Code, it is not expected that the Fund will be required to pay any Federal
income tax on such income and capital gains.
 
    With respect to the Fund's investments in zero coupon and payment-in-kind
bonds, the Fund accrues income prior to any actual cash payments by their
issuers. In order to continue to comply with Subchapter M of the Internal
Revenue Code and remain able to forego payment of Federal income tax on its
income and capital gains, the Fund must distribute all of its net investment
income, including income accrued from zero coupon and payment-in-kind bonds. As
such, the Fund may be required to dispose of some of its portfolio securities
under disadvantageous circumstances to generate the cash required for
distribution.
 
    Shareholders will normally have to pay Federal income taxes, and any
applicable state and/or local income taxes, on the dividends and distributions
they receive from the Fund. Such dividends and distributions, to the extent they
are derived from net investment income or net short-term capital gains, are
taxable to the shareholder as ordinary dividend income regardless of whether the
shareholder receives such distributions in additional shares or in cash. Any
dividends declared in the last calendar quarter of any year to shareholders of
record for that
 
                                       29
<PAGE>
period which are paid in the following year prior to February 1 will be deemed
received by the shareholder in the prior year. Since the Fund's income is
expected to be derived primarily from interest rather than dividends, only a
small portion, if any, of such dividends and distributions is expected to be
eligible for the Federal dividends received deduction available to corporations.
 
    Distributions of net long-term capital gains, if any, are taxable to
shareholders as long-term capital gains regardless of how long a shareholder has
held the Fund's shares and regardless of whether the distribution is received in
additional shares or in cash. Capital gains distributions are not eligible for
the dividends received deduction. Capital gains may be generated by transactions
in options and futures contracts engaged in by the Fund.
 
    The Fund may at times make payments from sources other than income or net
capital gains. Payments from such sources will, in effect, represent a return of
a portion of each shareholder's investment. All, or a portion, of such payments
will not be taxable to shareholders.
 
    After the end of the calendar year, shareholders will receive a statement of
their dividends and capital gains distributions for tax purposes, including
information as to the portion taxable as ordinary income and the portion taxable
as capital gains.
 
    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 regarding specific questions
as to state or local taxes and as to the applicability of the foregoing to their
current federal tax 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 will be
computed by dividing the Class's net investment income over a 30-day period by
an average value (using the average number of shares entitled to receive
dividends and the maximum offering price per share at the end of the period),
all in accordance with applicable regulatory requirements. Such amount will be
compounded for six months and then annualized for a twelve-month period to
derive the Fund's yield for each Class.
    
 
   
    The "average annual total return" of the Fund refers to a figure reflecting
the average annualized percentage increase (or decrease) in the value of an
initial investment in a Class of the Fund of $1,000 over periods of one, five
and ten years. Average annual total return reflects all income earned by the
Fund, any appreciation or depreciation of the Fund's assets, all expenses
incurred by the applicable Class and all sales charges incurred by shareholders,
for the stated periods. It also assumes reinvestment of all dividends and
distributions paid by the Fund.
    
 
   
    In addition to the foregoing, the Fund may advertise its total return for
each Class over different periods of time by means of aggregate, average,
year-by-year or other types of total return figures. Such calculations may or
may not reflect the deduction of any sales charge which, if reflected, would
reduce the performance quoted. The Fund may advertise the growth of hypothetical
investments of $10,000, $50,000 or $100,000 in each Class of shares of the Fund
 . The Fund from time to time may also advertise its performance relative to
certain performance rankings and indexes compiled by independent organizations,
such as mutual fund performance rankings of Lipper Analytical Services, Inc.

    Prior to July 28, 1997 the Fund offered only one Class of shares. Because
the distribution arrangement for Class A most closely resembles the distribution
arrangement applicable prior to the implementation of multiple classes,
historical performance information may be restated to reflect the current
maximum sales charge applicable to Class A. In addition, because all shares of
the Fund held prior to July 28, 1997 have been designated Class D shares, the
Fund's historical performance may also be restated to reflect the absence of any
sales charge in the case of Class D shares.
    
 
ADDITIONAL INFORMATION
- --------------------------------------------------------------------------------
 
   
    VOTING RIGHTS.  All shares of the Fund are of common stock 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.
    
 
    Under ordinary circumstances, the Fund is not required, nor does it intend,
to hold Annual Meetings of Stockholders. The Directors may call Special Meetings
of Stockholders for action by stockholder vote as may be required by the Act or
the Fund's By-Laws.
 
    CODE OF ETHICS.  Directors, officers and employees of InterCapital, Dean
Witter Services Company Inc. and the Distributor are subject to a strict Code of
Ethics adopted by those companies. The Code of Ethics is intended to ensure that
the interests of shareholders and other clients are placed ahead of any personal
interest, that no undue personal benefit is obtained from a person's employment
activities and that actual and potential conflicts of interest are avoided. To
achieve these goals and comply with regulatory requirements, the Code of Ethics
requires, among other things, that personal securities transactions by employees
of the companies be subject to an advance clearance process to monitor that no
Dean Witter Fund is engaged at the same time in a purchase or sale of the same
security. The Code of Ethics bans the purchase of securities in an initial
public offering, and also prohibits engaging in futures and options transactions
and profiting on short-term trading (that is, a purchase within 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.

APPENDIX -- RATINGS OF INVESTMENTS
- --------------------------------------------------------------------------------
 
MOODY'S INVESTORS SERVICE INC. ("MOODY'S")
                                  BOND RATINGS
 
<TABLE>
<S>        <C>
Aaa        Bonds which are rated Aaa are judged to be of the best quality. They carry the
           smallest degree of investment risk and are generally referred to as "gilt edge."
           Interest payments are protected by a large or by an exceptionally stable margin
           and principal is secure. While the various protective elements are likely to
           change, such changes as can be visualized are most unlikely to impair the
           fundamentally strong position of such issues.
Aa         Bonds which are rated Aa are judged to be of high quality by all standards.
           Together with the Aaa group they comprise what are generally known as high grade
           bonds. They are rated lower than the best bonds because margins of protection
           may not be as large as in Aaa securities or fluctuation of protective elements
           may be of greater amplitude or there may be other elements present which make
           the long-term risks appear somewhat larger than in Aaa securities.
A          Bonds which are rated A possess many favorable investment attributes and are to
           be considered as upper medium grade obligations. Factors giving security to
           principal and interest are considered adequate, but elements may be present
           which suggest a susceptibility to impairment sometime in the future.
Baa        Bonds which are rated Baa are considered as medium grade obligations; i.e., they
           are neither highly protected nor poorly secured. Interest payments and principal
           security appear adequate for the present but certain protective elements may be
           lacking or may be characteristically unreliable over any great length of time.
           Such bonds lack outstanding investment characteristics and in fact have
           speculative characteristics as well.
           Bonds rated Aaa, Aa, A and Baa are considered investment grade bonds.
 
Ba         Bonds which are rated Ba are judged to have speculative elements; their future
           cannot be considered as well assured. Often the protection of interest and
           principal payments may be very moderate, and therefore not well safeguarded
           during both good and bad times over the future. Uncertainty of position
           characterizes bonds in this class.
B          Bonds which are rated B generally lack characteristics of desirable investments.
           Assurance of interest and principal payments or of maintenance of other terms of
           the contract over any long period of time may be small.
Caa        Bonds which are rated Caa are of poor standing. Such issues may be in default or
           there may be present elements of danger with respect to principal or interest.
Ca         Bonds which are rated Ca present obligations which are speculative in a high
           degree. Such issues are often in default or have other marked shortcomings.
C          Bonds which are rated C are the lowest rated class of bonds, and issues so rated
           can be regarded as having extremely poor prospects of ever attaining any real
           investment standing.

                                       32
<PAGE>
        CONDITIONAL RATING:  Municipal bonds for which the security depends
    upon the completion of some act or the fulfillment of some condition are
    rated conditionally. These are bonds secured by (a) earnings of projects
    under construction, (b) earnings of projects unseasoned in operation
    experience, (c) rentals which begin when facilities are completed, or
    (d) payments to which some other limiting condition attaches.
    Parenthetical rating denotes probable credit stature upon completion of
    construction or elimination of basis of condition.
 
        RATING REFINEMENTS:  Moody's may apply numerical modifiers, 1, 2 and
    3 in each generic rating classification from Aa through B in its
    corporate and municipal bond rating system. The modifier 1 indicates
    that the security ranks in the higher end of its generic rating
    category; the modifier 2 indicates a mid-range ranking; and a modifier 3
    indicates that the issue ranks in the lower end of its generic rating
    category.
 
                            COMMERCIAL PAPER RATINGS
 
        Moody's Commercial Paper ratings are opinions of the ability to
    repay punctually promissory obligations not having an original maturity
    in excess of nine months. Moody's employs the following three
    designations, all judged to be investment grade, to indicate the
    relative repayment capacity of rated issuers: Prime-1, Prime-2, Prime-3.
 
        Issuers rated Prime-1 have a superior capacity for repayment of
    short-term promissory obligations. Issuers rated Prime-2 have a strong
    capacity for repayment of short-term promissory obligations; and Issuers
    rated Prime-3 have an acceptable capacity for repayment of short-term
    promissory obligations. Issuers rated Not Prime do not fall within any
    of the Prime rating categories.
 
    STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S")
 
                                  BOND RATINGS
 
        A Standard & Poor's bond rating is a current assessment of the
    creditworthiness of an obligor with respect to a specific obligation.
    This assessment may take into consideration obligors such as guarantors,
    insurers, or lessees.
 
        The ratings are based on current information furnished by the issuer
    or obtained by Standard & Poor's from other sources it considers
    reliable. The ratings are based, in varying degrees, on the following
    considerations: (1) likelihood of default-capacity and willingness of
    the obligor as to the timely payment of interest and repayment of
    principal in accordance with the terms of the obligation; (2) nature of
    and provisions of the obligation; and (3) protection afforded by, and
    relative position of, the obligation in the event of bankruptcy,
    reorganization or other arrangement under the laws of bankruptcy and
    other laws affecting creditors' rights.
 
        Standard & Poor's does not perform an audit in connection with any
    rating and may, on occasion, rely on unaudited financial information.
    The ratings may be changed, suspended or withdrawn as a result of
    changes in, or unavailability of, such information, or for other
    reasons.
 
<TABLE>
<S>        <C>
AAA        Debt rated AAA has the highest rating assigned by Standard & Poor's. Capacity to
           pay interest and repay principal is extremely strong.
AA         Debt rated AA has a very strong capacity to pay interest and repay principal and
           differs from the highest-rated issues only in small degree.
</TABLE>
 
                                       33
<PAGE>
<TABLE>
<S>        <C>
A          Debt rated A has a strong capacity to pay interest and repay principal although
           they are somewhat more susceptible to the adverse effects of changes in
           circumstances and economic conditions than debt in higher-rated categories.
BBB        Debt rated BBB is regarded as having an adequate capacity to pay interest and
           repay principal. Whereas it normally exhibits adequate protection parameters,
           adverse economic conditions or changing circumstances are more likely to lead to
           a weakened capacity to pay interest and repay principal for debt in this
           category than for debt in higher-rated categories.
           Bonds rated AAA, AA, A and BBB are considered investment grade bonds.
 
BB         Debt rated BB has less near-term vulnerability to default than other speculative
           grade debt. However, it faces major ongoing uncertainties or exposure to adverse
           business, financial or economic conditions which could lead to inadequate
           capacity to meet timely interest and principal payment.
B          Debt rated B has a greater vulnerability to default but presently has the
           capacity to meet interest payments and principal repayments. Adverse business,
           financial or economic conditions would likely impair capacity or willingness to
           pay interest and repay principal.
CCC        Debt rated CCC has a current identifiable vulnerability to default, and is
           dependent upon favorable business, financial and economic conditions to meet
           timely payments of interest and repayments of principal. In the event of adverse
           business, financial or economic conditions, it is not likely to have the
           capacity to pay interest and repay principal.
CC         The rating CC is typically applied to debt subordinated to senior debt which is
           assigned an actual or implied CCC rating.
C          The rating C is typically applied to debt subordinated to senior debt which is
           assigned an actual or implied CCC- debt rating.
CI         The rating CI is reserved for income bonds on which no interest is being paid.
NR         Indicates that no rating has been requested, that there is insufficient
           information on which to base a rating or that Standard & Poor's does not rate a
           particular type of obligation as a matter of policy.
 
           Bonds rated BB, B, CCC, CC and C are regarded as having predominantly
           speculative characteristics with respect to capacity to pay interest and repay
           principal. BB indicates the least degree of speculation and C the highest degree
           of speculation. While such debt will likely have some quality and protective
           characteristics, these are outweighed by large uncertainties or major risk
           exposures to adverse conditions.
 
           Plus (+) or minus (-): The ratings from AA to CCC may be modified by the
           addition of a plus or minus sign to show relative standing within the major
           ratings categories.
 
           In the case of municipal bonds, the foregoing ratings are sometimes followed by
           a "p" which indicates that the rating is provisional. A provisional rating
           assumes the successful completion of the project being financed by the bonds
           being rated and indicates that payment of debt service requirements is largely
           or entirely dependent upon the successful and timely completion of the project.
           This rating, however, while addressing credit quality subsequent to completion
           of the project, makes no comment on the likelihood or risk of default upon
           failure of such completion.
</TABLE>

<PAGE>
                            COMMERCIAL PAPER RATINGS
 
        Standard and Poor's commercial paper rating is a current assessment
    of the likelihood of timely payment of debt having an original maturity
    of no more than 365 days. The commercial paper rating is not a
    recommendation to purchase or sell a security. The ratings are based
    upon current information furnished by the issuer or obtained by S&P from
    other sources it considers reliable. The ratings may be changed,
    suspended, or withdrawn as a result of changes in or unavailability of
    such information. Ratings are graded into group categories, ranging from
    "A" for the highest quality obligations to "D" for the lowest. Ratings
    are applicable to both taxable and tax-exempt commercial paper. The
    categories are as follows:
 
        Issues assigned A ratings are regarded as having the greatest
    capacity for timely payment. Issues in this category are further refined
    with the designation 1, 2 and 3 to indicate the relative degree of
    safety.
 
<TABLE>
<S>        <C>
    A-1 indicates that the degree of safety regarding timely payment is very strong.
    A-2 indicates capacity for timely payment on issues with this designation is strong.
        However, the relative degree of safety is not as overwhelming as for issues
        designated "A-1".
    A-3 indicates a satisfactory capacity for timely payment. Obligations carrying this
        designation are, however, somewhat more vulnerable to the adverse effects of
        changes in circumstances than obligations carrying the higher designations.

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
THE FUND
 
    The Fund was incorporated under Maryland law on June 14, 1979, under the
name InterCapital High Yield Securities Inc. On March 16, 1983, the Fund's
shareholders approved a change in the Fund's name, effective March 21, 1983, to
Dean Witter High Yield Securities Inc.
 
THE INVESTMENT MANAGER
 
   
    Dean Witter InterCapital Inc. (the "Investment Manager" or "InterCapital"),
a Delaware corporation, whose address is Two World Trade Center, New York, New
York 10048, is the Fund's Investment Manager. InterCapital is a wholly-owned
subsidiary of Morgan Stanley, Dean Witter, Discover & Co., ("MSDWD"), a Delaware
corporation. In an internal reorganization which took place in January, 1993,
InterCapital assumed the investment advisory, administrative and management
activities previously performed by the InterCapital Division of Dean Witter
Reynolds Inc. ("DWR"), a broker-dealer affiliate of InterCapital. (As
hereinafter used in this Statement of Additional Information, the terms
"InterCapital" and "Investment Manager" refer to DWR's InterCapital Division
prior to the internal reorganization and to Dean Witter InterCapital Inc.
thereafter.) The daily management of the Fund and research relating to the
Fund's portfolio are conducted by or under the direction of officers of the Fund
and of the Investment Manager, subject to review by the Fund's Board of
Directors. Information as to these Directors and officers is contained under the
caption "Directors and Officers."

    In addition, Dean Witter Services Company Inc. ("DWSC"), a wholly-owned
subsidiary of InterCapital, serves as manager for the following investment
companies for which TCW Funds Management, Inc. is the investment adviser: TCW/DW
Core Equity Trust, TCW/DW North American Government Income Trust, TCW/DW Latin
American Growth Fund, TCW/DW Income and Growth Fund, TCW/DW Small Cap Growth
Fund, TCW/DW Balanced Fund, TCW/DW Total Return Trust, TCW/DW Mid-Cap Equity
Trust, TCW/DW Global Telecom Trust, TCW/DW Strategic Income Trust, TCW/DW
Emerging Markets Opportunites Trust, TCW/DW Term Trust 2000, TCW/DW Term Trust
2002 and TCW/DW Term Trust 2003 (the "TCW/DW Funds"). InterCapital also serves
as: (i) administrator of The BlackRock Strategic Term Trust Inc., a closed-end
investment company; and (ii) sub-administrator of MassMutual Participation
Investors and Templeton Global Governments Income Trust, closed-end investment
companies.
    
 
    Pursuant to an Investment Management Agreement (the "Agreement") with the
Investment Manager, the Fund has retained the Investment Manager to manage the
investment of the Fund's assets, including the placing of orders for the
purchase and sale of portfolio securities. The Investment Manager obtains and
evaluates such information and advice relating to the economy, securities
markets, and specific securities as it considers necessary or useful to
continuously manage the assets of the Fund in a manner consistent with its
investment objectives and policies.
 
    Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes, at its own expense, such office space, facilities,
equipment, clerical help and bookkeeping and certain legal services as the Fund
may reasonably require in the conduct of its business, including the preparation
of prospectuses, statements of additional information, proxy statements and
reports required to be filed with federal and state securities commissions
(except insofar as the participation or assistance of independent accountants
and attorneys is, in the opinion of the Investment Manager, necessary or
desirable). In addition, the Investment Manager pays the salaries of all
personnel, including officers of the Fund, who are employees of the Investment
Manager. The Investment Manager also bears the cost of telephone service, heat,
light, power and other utilities provided to the Fund.
 
    Effective December 31, 1993, pursuant to a Services Agreement between
InterCapital and DWSC, DWSC began to provide the administrative services to the
Fund which were previously performed directly by InterCapital. On April 17,
1995, DWSC was reorganized in the State of Delaware, necessitating the entry
into a new Services Agreement by InterCapital and DWSC on that date. The
foregoing internal reorganization did not result in any change in the nature or
scope of the administrative services being provided to the Fund or any of the
fees being paid by the Fund for the overall services being performed under the
terms of the existing Agreement.
 
   
    Expenses not expressly assumed by the Investment Manager under the Agreement
or by the Distributor of the Fund's shares, Dean Witter Distributors Inc.
("Distributors" or the "Distributor") (see "The Distributor"), will be paid by
the Fund. These expenses will be allocated among the four classes of shares of
the Fund (each, a "Class") pro rata based on the assets of the Fund attributable
to each Class, except as described below. The expenses borne by the Fund
include, but are not limited to: expenses of the Plan of Distribution pursuant
to Rule 12b-1 (the "12b-1 fee") (see "The Distributor"); charges and expenses of
any registrar, custodian, stock transfer and dividend disbursing agent;
brokerage commissions; taxes; engraving and printing of stock certificates;
registration costs of the Fund and its shares under federal and state securities
laws; the cost and expense of printing, including typesetting, and distributing
prospectuses of the Fund and supplements thereto to the Fund's shareholders; all
expenses of shareholders' and directors' meetings and of preparing, printing and
mailing of proxy statements and reports to shareholders; fees and travel
expenses of directors or members of any advisory board or committee who are not
employees of the Investment Manager or any corporate affiliate of the Investment
    
 
                                       4

Manager; all expenses incident to any dividend, distribution, withdrawal or
redemption options; charges and expenses of any outside service used for pricing
of the Fund's shares; fees and expenses of legal counsel, including counsel to
directors who are not interested persons of the Fund or of the Investment
Manager (not including compensation or expenses of attorneys who are employees
of the Investment Manager) and independent accountants; membership dues of
industry associations; interest on Fund borrowings; postage; insurance premiums
on property or personnel (including officers and directors) of the Fund which
inure to its benefit; extraordinary expenses (including, but not limited to,
legal claims and liabilities and litigation costs and any indemnification
relating thereto); and all other costs of the Fund's operation. The 12b-1 fees
relating to a particular Class will be allocated directly to that Class. In
addition, other expenses associated with a particular Class (except advisory or
custodial fees) may be allocated directly to that Class, provided that such
expenses are reasonably identified as specifically attributable to that Class
and the direct allocation to that Class is approved by the Directors.
    
 
   
    As full compensation for the services and facilities furnished to the Fund
and expenses of the Fund assumed by the Investment Manager, the Fund pays the
Investment Manager monthly compensation calculated daily by applying the
following annual rates to the net assets of the Fund determined as of the close
of each business day: 0.50% of the portion of the daily net assets not exceeding
$500 million; 0.425% of the portion of the daily net assets exceeding $500
million but not exceeding $750 million; 0.375% of the portion of the daily net
assets exceeding $750 million but not exceeding $1 billion; 0.35% of the portion
of the daily net assets exceeding $1 billion but not exceeding $2 billion;
0.325% of the portion of daily net assets exceeding $2 billion but not exceeding
$3 billion; and 0.30% of the portion of daily net assets exceeding $3 billion.
Total compensation accrued to the Investment Manager for the Fund's fiscal years
ended August 31, 1994, 1995 and 1996 amounted to $2,690,898, $2,241,952 and
$2,271,578, respectively.
    
 
    The Agreement provides that in the absence of willful misfeasance, bad
faith, gross negligence or reckless disregard of its obligations thereunder, the
Investment Manager is not liable to the Fund or any of its investors for any act
or omission by the Investment Manager or for any losses sustained by the Fund or
its investors. The Agreement in no way restricts the Investment Manager from
acting as investment manager or adviser to others.
 
   
    The Agreement was initially approved by the Directors on February 21, 1997
and by the shareholders of the Fund at a Special Meeting of Shareholders held on
May 21, 1997. The Agreement is substantially identical to a prior investment
management agreement which was initially approved by the Board of Directors on
October 30, 1992 and by the shareholders of the Fund at a Special Meeting of
Shareholders held on January 12, 1993. The Agreement took effect on May 31, 1997
upon the consummation of the merger of Dean Witter, Discover & Co. with Morgan
Stanley Group Inc. The Agreement may be terminated at any time, without penalty,
on thirty days' notice, by the Board of Directors of the Fund, by the holders of
a majority, as defined in the Investment Company Act of 1940, as amended (the
"Act"), of the outstanding shares of the Fund, or by the Investment Manager. The
Agreement will automatically terminate in the event of its assignment (as
defined in the Act).
    
 
   
    Under its terms, the Agreement has an initial term ending April 30, 1999,
and will remain in effect from year to year thereafter, provided continuation of
the Agreement is approved at least annually by the vote of the holders of a
majority, as defined in the Act, of the outstanding shares of the Fund, or by
the Board of Directors of the Fund; provided that in either event such
continuance is approved annually by the vote of a majority of the Directors of
the Fund who are not parties to the Agreement or "interested persons" (as
defined in the Act) of any such party (the "Independent Directors"), which vote
must be cast in person at a meeting called for the purpose of voting on such
approval.
    
 
   
    The Fund has acknowledged that the name "Dean Witter" is a property right of
DWR. The Fund has agreed that DWR or its parent company may use or, at any time,
permit others to use, the name "Dean Witter." The Fund has also agreed that in
the event the Agreement between InterCapital and the Fund is terminated, or if
the affiliation between InterCapital and its parent company is terminated, the
Fund will eliminate the name "Dean Witter" from its name if DWR or its parent
company shall so request.

THE BOARD OF DIRECTORS, THE INDEPENDENT DIRECTORS, AND THE COMMITTEES
 
   
    The Board of Directors currently consists of eight (8) directors; as noted
above, Mr. Hedien's term will commence on September 1, 1997. These same
individuals also serve as directors or trustees for all of the Dean Witter
Funds, and are referred to in this section as Directors. As of the date of this
Statement of Additional Information, there are a total of 83 Dean Witter Funds,
comprised of 126 portfolios. As of June 30, 1997, the Dean Witter Funds had
total net assets of approximately $  billion and more than six million
shareholders.
    
 
   
    Six Directors and Mr. Hedien (77% of the total number) have no affiliation
or business connection with InterCapital or any of its affiliated persons and do
not own any stock or other securities issued by InterCapital's parent company,
MSDWD. These are the "disinterested" or "independent" Directors. The other two
Directors (the "management Directors") are affiliated with InterCapital. Four of
the six independent Directors are also Independent Trustees of the TCW/DW Funds.
    
 
    Law and regulation establish both general guidelines and specific duties for
the Independent Directors. The Dean Witter Funds seek as Independent Directors
or Trustees individuals of distinction and experience in business and finance,
government service or academia; these are people whose advice and counsel are in
demand by others and for whom there is often competition. To accept a position
on the Funds' Boards, such individuals may reject other attractive assignments
because the Funds make substantial demands on their time. Indeed, by serving on
the Funds' Boards, certain Directors or Trustees who would otherwise be
qualified and in demand to serve on bank boards would be prohibited by law from
doing so.
 
   
    All of the current Independent Directors serve as members of the Audit
Committee and the Committee of the Independent Directors. Three of them also
serve as members of the Derivatives Committee. During the calendar year ended
December 31, 1996, the three Committees held a combined total of sixteen
meetings. The Committees hold some meetings at InterCapital's offices and some
outside InterCapital. Management Directors or officers do not attend these
meetings unless they are invited for purposes of furnishing information or
making a report.
    
 
    The Committee of the Independent Directors is charged with recommending to
the full Board approval of management, advisory and administration contracts,
Rule 12b-1 plans and distribution and
 
                                       8
<PAGE>
underwriting agreements; continually reviewing Fund performance; checking on the
pricing of portfolio securities, brokerage commissions, transfer agent costs and
performance, and trading among Funds in the same complex; and approving fidelity
bond and related insurance coverage and allocations, as well as other matters
that arise from time to time. The Independent Directors are required to select
and nominate individuals to fill any Independent Director vacancy on the Board
of any Fund that has a Rule 12b-1 plan of distribution. Most of the Dean Witter
Funds have such a plan.
 
    The Audit Committee is charged with recommending to the full Board the
engagement or discharge of the Fund's independent accountants; directing
investigations into matters within the scope of the independent accountants'
duties, including the power to retain outside specialists; reviewing with the
independent accountants the audit plan and results of the auditing engagement;
approving professional services provided by the independent accountants and
other accounting firms prior to the performance of such services; reviewing the
independence of the independent accountants; considering the range of audit and
non-audit fees; reviewing the adequacy of the Fund's system of internal
controls; and preparing and submitting Committee meeting minutes to the full
Board.
 
    Finally, the Board of each Fund has formed a Derivatives Committee to
establish parameters for and oversee the activities of the Fund with respect to
derivative investments, if any, made by the Fund.
 
DUTIES OF CHAIRMAN OF COMMITTEE OF THE INDEPENDENT DIRECTORS AND AUDIT COMMITTEE
 
    The Chairman of the Committee of the Independent Directors and the Audit
Committee maintains an office at the Funds' headquarters in New York. He is
responsible for keeping abreast of regulatory and industry developments and the
Funds' operations and management. He screens and/or prepares written materials
and identifies critical issues for the Independent Directors to consider,
develops agendas for Committee meetings, determines the type and amount of
information that the Committees will need to form a judgment on various issues,
and arranges to have that information furnished to Committee members. He also
arranges for the services of independent experts and consults with them in
advance of meetings to help refine reports and to focus on critical issues.
Members of the Committees believe that the person who serves as Chairman of both
Committees and guides their efforts is pivotal to the effective functioning of
the Committees.
 
    The Chairman of the Committees also maintains continuous contact with the
Funds' management, with independent counsel to the Independent Directors and
with the Funds' independent auditors. He arranges for a series of special
meetings involving the annual review of investment advisory, management and
other operating contracts of the Funds and, on behalf of the Committees,
conducts negotiations with the Investment Manager and other service providers.
In effect, the Chairman of the Committees serves as a combination of chief
executive and support staff of the Independent Directors.
 
   
    The Chairman of the Committee of the Independent Directors and the Audit
Committee is not employed by any other organization and devotes his time
primarily to the services he performs as Committee Chairman and Independent
Director of the Dean Witter Funds and as an Independent Director and, since July
1, 1996, as Chairman of the Committee of the Independent Trustees and the Audit
Committee of the TCW/DW Funds. The current Committee Chairman has had more than
35 years experience as a senior executive in the investment company industry.
    
 
   
ADVANTAGES OF HAVING SAME INDIVIDUALS AS INDEPENDENT DIRECTORS FOR ALL DEAN
WITTER FUNDS
    
 
   
    The Independent Directors and the Funds' management believe that having the
same Independent Directors for each of the Dean Witter Funds avoids the
duplication of effort that would arise from having different groups of
individuals serving as Independent Directors for each of the Funds or even of
sub-groups of Funds. They believe that having the same individuals serve as
Independent Directors of all the Funds tends to increase their knowledge and
expertise regarding matters which affect the Fund complex generally and enhances
their ability to negotiate on behalf of each Fund with the Fund's service
providers. This arrangement also precludes the possibility of separate groups of
Independent Directors arriving at conflicting decisions regarding operations and
management of the Funds and avoids the cost and confusion that would likely
ensue. Finally, having the same Independent Directors serve on all Fund
    
 
                                       9
<PAGE>
   
Boards enhances the ability of each Fund to obtain, at modest cost to each
separate Fund, the services of Independent Directors, and a Chairman of their
Committees, of the caliber, experience and business acumen of the individuals
who serve as Independent Directors of the Dean Witter Funds.
    
 
   
COMPENSATION OF INDEPENDENT DIRECTORS
    
 
    The Fund pays each Independent Director an annual fee of $1,000 plus a per
meeting fee of $50 for meetings of the Board of Directors or committees of the
Board of Directors attended by the Director (the Fund pays the Chairman of the
Audit Committee an annual fee of $750 and pays the Chairman of the Committee of
the Independent Directors an additional annual fee of $1,200). The Fund also
reimburses such Directors for travel and other out-of-pocket expenses incurred
by them in connection with attending such meetings. Directors and officers of
the Fund who are or have been employed by the Investment Manager or an
affiliated company receive no compensation or expense reimbursement from the
Fund.
 
    The following table illustrates the compensation paid to the Fund's
Independent Directors by the Fund for the fiscal year ended August 31, 1996.

    As of the date of this Statement of Additional Information, 57 of the Dean
Witter Funds, including the Fund, have adopted a retirement program under which
an Independent Director who retires after serving for at least five years (or
such lesser period as may be determined by the Board) as an Independent Director
or Trustee of any Dean Witter Fund that has adopted the retirement program (each
such Fund referred to as an "Adopting Fund" and each such Director referred to
as an "Eligible Director") is entitled to retirement payments upon reaching the
eligible retirement age (normally, after attaining age 72). Annual payments are
based upon length of service. Currently, upon retirement, each Eligible Director
is entitled to receive from the Adopting Fund, commencing as of his or her
retirement date and continuing
    
 
                                       10
<PAGE>
   
for the remainder of his or her life, an annual retirement benefit (the "Regular
Benefit") equal to 25.0% of his or her Eligible Compensation plus 0.4166666% of
such Eligible Compensation for each full month of service as an Independent
Director or Trustee of any Adopting Fund in excess of five years up to a maximum
of 50.0% after ten years of service. The foregoing percentages may be changed by
the Board.(1) "Eligible Compensation" is one-fifth of the total compensation
earned by such Eligible Director for service to the Adopting Fund in the five
year period prior to the date of the Eligible Director's retirement. Benefits
under the retirement program are not secured or funded by the Adopting Funds.
    
 
   
    The following table illustrates the retirement benefits accrued to the
Fund's Independent Directors by the Fund for the fiscal year ended August 31,
1996 and by the 57 Dean Witter Funds (including the Fund) as of December 31,
1996, and the estimated retirement benefits for the Fund's Independent
Directors, to commence upon their retirement, from the Fund as of August 31,
1996 and from the 57 Dean Witter Funds as of December 31, 1996.

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

    varies depending on the Director's elections described in Footnote (1)

    As of the date of this Statement of Additional Information, the aggregate
number of shares of beneficial interest of the Fund owned by the Fund's officers
and Directors as a group was less than 1 percent of the Fund's shares of
beneficial interest outstanding.
 
INVESTMENT PRACTICES AND POLICIES
- --------------------------------------------------------------------------------
 
    As discussed in the Prospectus, the Fund will invest principally in
fixed-income securities rated Baa or lower by Moody's Investor's Service Inc.
("Moody's"), or BBB or lower by Standard & Poor's Corporation ("Standard &
Poor's"). The ratings of fixed-income securities by Moody's and Standard &
Poor's are a generally accepted barometer of credit risk. They are, however,
subject to certain limitations from an investor's standpoint.
 
    Such limitations include the following: the rating of an issuer is heavily
weighted by past developments and does not necessarily reflect probable future
conditions; there is frequently a lag between the time a rating is assigned and
the time it is updated; and there may be varying degrees of difference in credit
risk of securities in each rating category. The Investment Manager will attempt
to reduce the overall portfolio credit risk through diversification and
selection of portfolio securities based on considerations mentioned below.
 
                                       11
<PAGE>
    While the ratings provide a generally useful guide to credit risks, they do
not, nor do they purport to, offer any criteria for evaluating the interest rate
risk. Changes in the general level of interest rates cause fluctuations in the
prices of fixed-income securities already outstanding and will therefore result
in fluctuation in net asset value of the Fund's shares. The extent of the
fluctuation is determined by a complex interaction of a number of factors. The
Investment Manager will evaluate those factors it considers relevant and will
make portfolio changes when it deems it appropriate in seeking to reduce the
risk of depreciation in the value of the Fund's portfolio. However, in seeking
to achieve the Fund's primary objective, there will be times, such as during
periods of rising interest rates, when depreciation and realization of capital
losses on securities in the portfolio will be unavoidable. Moreover, medium and
lower-rated securities and non-rated securities of comparable quality tend to be
subject to wider fluctuations in yield and market values than higher rated
securities. Such fluctuations after a security is acquired do not affect the
cash income received from that security but are reflected in the net asset value
of the Fund's portfolio.
 
PORTFOLIO CHARACTERISTICS
 
    LENDING OF PORTFOLIO SECURITIES.  Consistent with applicable regulatory
requirements and subject to Investment Restriction 8 below, the Fund may lend
its portfolio securities to brokers, dealers and other financial institutions,
provided that such loans are callable at any time by the Fund (subject to notice
provisions described below), and are at all times secured by cash or cash
equivalents, which are maintained in a segregated account pursuant to applicable
regulations and that are equal to at least the market value, determined daily,
of the loaned securities. The advantage of such loans is that the Fund continues
to receive the income on the loaned securities while at the same time earning
interest on the cash amounts deposited as collateral, which will be invested in
short-term obligations. The Fund will not lend its portfolio securities if such
loans are not permitted by the laws or regulations of any state in which its
shares are qualified for sale and will not lend more than 25% of the value of
its total assets.
 
    A loan may be terminated by the borrower on one business day's notice, or by
the Fund on four business days' notice. If the borrower fails to deliver the
loaned securities within four days after receipt of notice, the Fund could use
the collateral to replace the securities while holding the borrower liable for
any excess of replacement cost over the value of the collateral. As with any
extensions of credit, there are risks of delay in recovery and, in some cases,
even loss of rights in the collateral should the borrower of the securities fail
financially. However, these loans of portfolio securities will only be made to
firms deemed by the Fund's management to be creditworthy and when the income
which can be earned from such loans justifies the attendant risks. Upon
termination of the loan, the borrower is required to return the securities to
the Fund. Any gain or loss in the market price during the loan period would
inure to the Fund. The creditworthiness of firms to which the Fund lends its
portfolio securities will be monitored on an ongoing basis by the Investment
Manager pursuant to procedures adopted and reviewed, on an ongoing basis, by the
Board of Directors of the Fund.
 
    When voting or consent rights which accompany loaned securities pass to the
borrower, the Fund will follow the policy of calling the loaned securities, in
whole or in part as may be appropriate, to be delivered within one day after
notice, to permit the exercise of such rights if the matters involved would have
a material effect on the Fund's investment in such loaned securities. The Fund
will pay reasonable finder's, administrative and custodial fees in connection
with a loan of its securities. The Fund did not lend any of its portfolio
securities during its fiscal year ended August 31, 1996.
 
    REPURCHASE AGREEMENTS.  When cash may be available for only a few days, it
may be invested by the Fund in repurchase agreements until such time as it may
otherwise be invested or used for payments of obligations of the Fund. These
agreements, which may be viewed as a type of secured lending by the Fund,
typically involve the acquisition by the Fund of debt securities from a selling
financial institution such as a bank, savings and loan association or
broker-dealer. The agreement provides that the Fund will sell back to the
institution, and that the institution will repurchase, the underlying security
("collateral"), which is held by the Fund's Custodian, at a specified price and
at a fixed time in the future, usually not more than seven days from the date of
purchase. The Fund will accrue interest from the institution until the time when
the repurchase is to occur. Although such date is deemed by the Fund to be the
 
                                       12
<PAGE>
maturity date of a repurchase agreement, the maturities of securities subject to
repurchase agreements are not subject to any limits and may exceed one year.
While repurchase agreements involve certain risks not associated with direct
investments in debt securities, the Fund follows procedures designed to minimize
such risks. These procedures include effecting repurchase transactions only with
large, well-capitalized and well-established financial institutions, whose
financial condition will be continually monitored by the Investment Manager
subject to procedures established by the Board of Directors of the Fund. In
addition, the value of the collateral underlying the repurchase agreement will
always be at least equal to the repurchase price, including any accrued interest
earned on the repurchase agreement. In the event of a default or bankruptcy by a
selling financial institution, the Fund will seek to liquidate such collateral.
However, the exercising of the Fund's right to liquidate such collateral could
involve certain costs or delays and, to the extent that proceeds from any sale
upon a default of the obligation to repurchase were less than the repurchase
price, the Fund could suffer a loss. It is the current policy of the Fund not to
invest in repurchase agreements that do not mature within seven days if any such
investment, together with any other illiquid assets held by the Fund, amounts to
more than 10% of its total assets. The Fund's investments in repurchase
agreements may at times be substantial when, in the view of the Investment
Manager, liquidity or other considerations warrant. During the fiscal year ended
August 31, 1996, the Fund's investments in repurchase agreements did not exceed
5% of its total net assets.
 
    SECURITIES OF FOREIGN ISSUERS.  The Fund may invest up to 20% of its total
assets in fixed-income securities issued by foreign governments and other
foreign issuers and in foreign currency issues of domestic issuers, but not more
than 10% of its total assets in such securities, whether issued by a foreign or
domestic issuer, which are denominated in foreign currency. The Fund believes
that in many instances such foreign fixed-income securities may provide higher
yields than similar securities of domestic issuers. With the expiration of the
Interest Equalization Tax in 1974, many of these investments currently enjoy
increased liquidity, although such securities are generally less liquid than the
securities of United States corporations, and are certainly less liquid than
securities issued by the United States Government or its agencies.
 
   
    Foreign investments involve certain risks, including the political or
economic instability of the issuer or of the country of issue, the difficulty of
predicting international trade patterns and the possibility of imposition of
exchange controls. Such securities may also be subject to greater fluctuations
in price than securities of United States corporations or of the United States
Government. In addition, there may be less publicly available information about
a foreign company than about a domestic company. Foreign companies generally are
not subject to uniform accounting, auditing and financial reporting standards
comparable to those applicable to domestic companies. There is generally less
government regulation of stock exchanges, brokers and listed companies abroad
than in the United States, and with respect to certain foreign countries, there
is a possibility of expropriation or confiscatory taxation, or diplomatic
developments which could affect investment in those countries. Finally, in the
event of a default of any such foreign debt obligations, it may be more
difficult for the Fund to obtain or to enforce a judgment against the issuers of
such securities. In addition to the above-mentioned risks, securities
denominated in foreign currency, whether issued by a foreign or a domestic
issuer, may be affected favorably or unfavorably by changes in currency rates
and in exchange control regulations, and costs may be incurred in connection
with conversions between various currencies. It may not be possible to hedge
against the risks of currency fluctuation.
    
 
    PUBLIC UTILITIES.  As stated in the Prospectus, the Fund's investments in
public utilities, if any, may be subject to certain risks. Such utilities may
have difficulty meeting environmental standards and obtaining satisfactory fuel
supplies at reasonable costs. During an inflationary period, public utilities
also face increasing fuel, construction and other costs and may have difficulty
realizing an adequate return on invested capital. There is no assurance that
regulatory authorities will grant sufficient rate increases to cover expenses
associated with the foregoing difficulties as well as debt service requirements.
In addition, with respect to utilities engaged in nuclear power generation,
there is the possibility that
 
                                       13
<PAGE>
Federal, State or municipal governmental authorities may from time to time
impose additional regulations or take other governmental action which might
cause delays in the licensing, construction, or operation of nuclear power
plants, or suspension of operation of such plants which have been or are being
financed by proceeds of the fixed income securities in the Fund's portfolio.
 
   
    WHEN-ISSUED AND DELAYED DELIVERY SECURITIES.  As discussed in the
Prospectus, from time to time, in the ordinary course of business, the Fund may
purchase securities on a when-issued or delayed delivery basis, I.E., delivery
and payment can take place a month or more after the date of the transactions.
The securities so purchased are subject to market fluctuation and no interest
accrues to the purchaser during this period. At the time the Fund makes the
commitment to purchase securities on a when-issued, delayed delivery basis or
forward commitment basis with the intention of acquiring the securities, it will
record the transaction and thereafter reflect the value, each day, of such
security in determining the net asset value of the Fund. At the time of delivery
of the securities, the value may be more or less than the purchase price. The
Fund will also establish a segregated account with its custodian bank in which
it will maintain cash or U.S. Government Securities or other liquid portfolio
securities equal in value to commitments for such when-issued or delayed
delivery securities; subject to this requirement, the Fund may purchase
securities on such basis without limit. An increase in the percentage of the
Fund's assets committed to the purchase of securities on a when-issued or
delayed delivery basis may increase the volatility of the Fund's net asset
value. The Investment Manager and the Board of Directors do not believe that the
Fund's net asset value or income will be adversely affected by its purchase of
securities on such basis. The Fund may sell securities on a when-issued or
delayed delivery basis provided that the Fund owns the security at the time of
the sale. During the fiscal year ended August 31, 1996, the Fund did not
purchase any when-issued and delayed delivery securities.
    
 
    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 buy-out or debt restructuring. The
commitment for the purchase of any such security will not be recognized in the
portfolio of the Fund until the Investment Manager determines that issuance of
the security is probable. At such time, the Fund will record the transaction
and, in determining its net asset value, will reflect the value of the security
daily. At such time, the Fund will also establish a segregated account with its
custodian bank in which it will maintain cash or U.S. Government Securities or
other liquid portfolio securities equal in value to recognized commitments for
such securities. Once a segregated account has been established, if the
anticipated event does not occur and the securities are not issued the Fund will
have lost an investment opportunity. The value of the Fund's commitments to
purchase the securities of any one issuer, together with the value of all
securities of such issuer owned by the Fund, may not exceed 5% of the value of
the Fund's total assets at the time the initial commitment to purchase such
securities is made (see "Investment Restrictions" in the Prospectus). Subject to
the foregoing restrictions, the Fund may purchase securities on such basis
without limit. An increase in the percentage of the Fund's assets committed to
the purchase of securities on a "when, as and if issued" basis may increase the
volatility of its net asset value. The Investment Manager and the Board of
Directors do not believe that the net asset value of the Fund will be adversely
affected by its purchase of securities on such basis. The Fund may also sell
securities on a "when, as and if issued" basis provided that the issuance of the
security will result automatically from the exchange or conversion of a security
owned by the Fund at the time of the sale. During the fiscal year ended August
31, 1996, the Fund did not purchase securities on a when, as and if issued basis
in an amount which exceeded 5% of its total net assets.
 
    FUTURES CONTRACTS AND OPTIONS ON FUTURES.  As discussed in the Prospectus,
the Fund may invest in financial futures contracts ("futures contracts") and
related options thereon. These futures contracts and related options thereon
will be used only as a hedge against anticipated interest rate changes. A
futures contract sale creates an obligation by the Fund, as seller, to deliver
the specific type of instrument called for in the contract at a specified future
time for a specified price. A futures contract purchase would create an
obligation by the Fund, as purchaser, to take delivery of the specific type of
financial instrument
 
                                       14
<PAGE>
at a specified future time at a specified price. The specific securities
delivered or taken, respectively, at settlement date, would not be determined
until or near that date. The determination would be in accordance with the rules
of the exchange on which the futures contract sale or purchase was effected.
 
    The Fund may sell a futures contract or a call option thereon or purchase a
put option on such futures contract, if the Investment Manager anticipates
interest rates to rise, as a hedge against a decrease in the value of the Fund's
portfolio securities. If the Investment Manager anticipates that interest rates
will decline, the Fund may purchase a futures contract or a call option thereon
or sell a put option on such futures contract to protect against an increase in
the price of the securities the Fund intends to purchase. These futures
contracts and related options thereon will be used only as a hedge against
anticipated interest rate changes.
 
    The Fund may not enter into futures contracts or purchase related options
thereon if immediately thereafter the amount committed to margin plus the amount
paid for premiums for unexpired options on futures contracts exceeds 5% of the
value of the Fund's total assets. The Fund may not purchase or sell futures
contracts or related options thereon if, immediately thereafter, more than
one-third of its net assets would be hedged. The Fund did not enter into any
futures transactions during its fiscal year ended August 31, 1996.
 
    Although the terms of futures contracts specify actual delivery or receipt
of securities, in most instances the contracts are closed out before the
settlement date without the making or taking of delivery of the securities.
Closing out of a futures contract is usually effected by entering into an
offsetting transaction. An offsetting transaction for a futures contract sale is
effected by the Fund entering into a futures contract purchase for the same
aggregate amount of the specific type of financial instrument and same delivery
date. If the price in the sale exceeds the price in the offsetting purchase, the
Fund is immediately paid the difference and thus realizes a gain. If the
offsetting purchase price exceeds the sale price, the Fund pays the difference
and realizes a loss. Similarly, the closing out of a futures contract purchase
is effected by the Fund entering into a futures contract sale. If the offsetting
sale price exceeds the purchase price, the Fund realizes a gain, and if the
offsetting sale price is less than the purchase price, the Fund realizes a loss.
 
    Unlike a futures contract, which requires the parties to buy and sell a
security on a set date, an option on a futures contract entitles its holder to
decide on or before a future date whether to enter into such a contract. If the
holder decides not to enter into the contract, the premium paid for the contract
is lost. Since the price of the option is fixed at the point of sale, there are
no daily payments of cash to reflect the change in the value of the underlying
contract, as discussed below for futures contracts. The value of the option does
change and is reflected in the net asset value of the Fund.
 
    The Fund is required to maintain margin deposits with brokerage firms
through which it effects futures contracts and options thereon. The initial
margin requirements vary according to the type of the underlying security. In
addition, due to current industry practice, daily variations in gains and losses
on open contracts are required to be reflected in cash in the form of variation
margin payments. The Fund may be required to make additional margin payments
during the term of the contract.
 
    Currently, futures contracts can be purchased on debt securities such as
U.S. Treasury Bills and Bonds, U.S. Treasury Notes with maturities between 6 1/2
and 10 years, Certificates of the Government National Mortgage Association and
Bank Certificates of Deposit. The Fund may invest in interest rate futures
contracts covering these types of financial instruments as well as in new types
of such contracts that become available in the future.
 
                                       15
<PAGE>
    Financial futures contracts are traded in an auction environment on the
floors of several Exchanges -- principally, the Chicago Board of Trade, the
Chicago Mercantile Exchange and the New York Futures Exchange. Each Exchange
guarantees performance under contract provisions through a clearing corporation,
a nonprofit organization managed by the Exchange membership which is also
responsible for handling daily accounting of deposits or withdrawals of margin.
 
    A risk in employing futures contracts to protect against the price
volatility of portfolio securities is that the prices of securities subject to
futures contracts may correlate imperfectly with the behavior of the cash prices
of the Fund's portfolio securities. The correlation may be distorted by the fact
that the futures market is dominated by short-term traders seeking to profit
from the difference between a contract or security price objective and their
cost of borrowed funds. This would reduce their value for hedging purposes over
a short time period. Such distortions are generally minor and would diminish as
the contract approached maturity.
 
    Another risk is that the Fund's manager could be incorrect in its
expectations as to the direction or extent of various interest rate movements or
the time span within which the movements take place. For example, if the Fund
sold futures contracts for the sale of securities in anticipation of an increase
in interest rates, and then interest rates went down instead, causing bond
prices to rise, the Fund would lose money on the sale.
 
    Put and call options on financial futures have similar characteristics as
Exchange traded options. For a further description of options, see below and
pages 7 and 8 of the Prospectus.
 
    In addition to the risks associated in investing in options on securities,
there are particular risks associated with investing in options on futures. In
particular, the ability to establish and close out positions on such options
will be subject to the development and maintenance of a liquid secondary market.
It is not certain that this market will develop.
 
    A substantial majority (i.e., approximately 75%) of all anticipatory hedge
transactions (transactions in which the Fund does not own at the time of the
transaction, but expects to acquire, the securities underlying the relevant
futures contract) involving the purchase of futures contracts, call options or
written put options thereon will be completed by the purchase of securities
which are the subject of the hedge.
 
    The Fund may not enter into futures contracts or related options thereon if,
immediately thereafter, the amount committed to margin plus the amount paid for
option premiums exceeds 5% of the value of the Fund's total assets. In instances
involving the purchase of futures contracts by the Fund, an amount equal to the
market value of the futures contract will be deposited in a segregated account
of cash and cash equivalents to collateralize the position and thereby ensure
that the use of such futures contract is unleveraged. The Fund may not purchase
or sell futures contracts or related options if, immediately thereafter, more
than one-third of its net assets would be hedged.
 
    OPTIONS.  As discussed in the Prospectus, the Fund may purchase or sell
options on debt securities. The Fund would only buy options listed on national
securities exchanges, except for agreements, sometimes called cash puts, which
may accompany the purchase of a new issue of bonds from a dealer.
 
    A call option is a contract that gives the holder of the option the right to
buy from the writer (seller) of the call option, in return for a premium, the
security underlying the option at a specified exercise price at any time during
the term of the option. The writer of the call option has the obligation upon
exercise of the option to deliver the underlying security upon payment of the
exercise price during the option period. A put option is a contract that gives
the holder of the option the right to sell to the writer, in return for a
premium, the underlying security at a specified price during the term of the
option. The writer of the put has the obligation to buy the underlying security
upon exercise, at the exercise price during the option period. The Fund did not
enter into any options transactions during its fiscal year ended August 31,
1995, and it has no intention of doing so during the forseeable future.
 
                                       16
<PAGE>
    The Fund will only write covered call or covered put options. The Fund may
only write covered options which are listed on national securities exchanges.
The Fund may not write covered options in an amount exceeding 20% of the value
of its total assets. A call option is "covered" if the Fund owns the underlying
security covered by the call or has an absolute and immediate right to acquire
that security without additional cash consideration (or for additional cash
consideration held in a segregated account by its custodian) upon conversion or
exchange of other securities held in its portfolio. A call option is also
covered if the Fund holds, on a share-for-share basis, a call on the same
security as the call written where the exercise price of the call held is (i)
equal to or less than the exercise price of the call written or (ii) greater
than the exercise price of the call written if the difference is maintained by
the Fund in cash, Treasury bills or other liquid portfolio securities in a
segregated account with its custodian. A put option is "covered" if the Fund
maintains cash, Treasury bills or other liquid portfolio securities with a value
equal to the exercise price in a segregated account with its custodian, or else
holds, on a share-for-share basis, a put on the same security as the put written
where the exercise price of the put held is equal to or greater than the
exercise price of the put written.
 
    If the Fund has written an option, it may terminate its obligation by
effecting a closing purchase transaction. This is accomplished by purchasing an
option of the same series as the option previously written. However, once the
Fund has been assigned an exercise notice, the Fund will be unable to effect a
closing purchase transaction. Similarly, if the Fund is the holder of an option
it may liquidate its position by effecting a closing sale transaction. This is
accomplished by selling an option of the same series as the option previously
purchased. There can be no assurance that either a closing purchase or sale
transaction can be effected when the Fund so desires. The Fund may only buy
options which are listed on national securities exchanges. The Fund will not
purchase options if, as a result, the aggregate cost of all outstanding options
exceeds 10% of the Fund's total assets.
 
    The Fund will realize a profit from a closing transaction if the price of
the transaction is less than the premium received from writing the option or is
more than the premium paid to purchase the option; the Fund will realize a loss
from a closing transaction if the price of the transaction is more than the
premium received from writing the option or is less than the premium paid to
purchase the option. Since call option prices generally reflect increases in the
price of the underlying security, any loss resulting from the repurchase of a
call option may also be wholly or partially offset by unrealized appreciation of
the underlying security. If a put option written by the Fund is exercised, the
Fund may incur a loss equal to the difference between the exercise price of the
option and the sum of the sale price of the underlying security plus the premium
received from the sale of the option. Other principal factors affecting the
market value of a put or a call option include supply and demand, interest
rates, the current market price and price volatility of the underlying security
and the time remaining until the expiration date.
 
    An option position may be closed out only on an exchange which provides a
secondary market for an option of the same series. Although the Fund will
generally purchase or write only those options for which there appears to be an
active secondary market, there is no assurance that a liquid secondary market on
an exchange will exist for any particular option. In such event, it might not be
possible to effect closing transactions in particular options, so that the Fund
would have to exercise its options in order to realize any profit and would
incur brokerage commissions upon the exercise of call options and upon the
subsequent disposition of underlying securities for the exercise of put options.
If the Fund as a covered call option writer is unable to effect a closing
purchase transaction in a secondary market, it will not be able to sell the
underlying security until the option expires or it delivers the underlying
security upon exercise.
 
    The Fund now qualifies and intends to remain qualified as a "regulated
investment company" under the Internal Revenue Code (see "Dividends,
Distributions and Taxes"). One requirement for such qualification is that less
than 30% of the Fund's gross income must be derived from the gains from the sale
or other disposition of securities held for less than three months. Therefore,
the Fund may be limited in its ability to engage in futures and options
transactions.

INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    In addition to the investment restrictions enumerated in the Prospectus, the
investment restrictions listed below have been adopted by the Fund as
fundamental policies, which may not be changed without the vote of a majority of
the outstanding voting securities of the Fund, as defined in the Act. Such a
majority is defined as the lesser of (a) 67% of the shares present at a meeting
of shareholders, if the holders of more than 50% of the outstanding shares of
the Fund are present or represented by proxy, or (b) more than 50% of the
outstanding shares of the Fund.
 
    The Fund may not:
 
        1. Make short sales of securities;
 
        2. Purchase securities on margin, except for such short-term loans as
           are necessary for the clearance of purchases of portfolio securities;
 
        3. Pledge its assets or assign or otherwise encumber them in excess of
           4.5% of its net assets (taken at market value at the time of
    pledging) and then only to secure borrowings effected within the limitations
    set forth in Restriction 14. For the purpose of this restriction, collateral
    arrangements with respect to the writing of options and collateral
    arrangements with respect to initial margin for futures are not deemed to be
    pledges of assets;
 
        4. Engage in the underwriting of securities except insofar as the Fund
           may be deemed an underwriter under the Securities Act of 1933 in
    disposing of a portfolio security;
 
        5. Purchase or sell real estate or interests therein, although it may
           purchase securities of issuers which engage in real estate operations
    and securities which are secured by real estate or interests therein;
 
        6. Purchase or sell commodities except that the Fund may purchase
           financial futures contracts and related options;
 
        7. Make loans of money or securities, except (a) by the purchase of debt
           obligations in which the Fund may invest consistent with its
    investment objectives and policies; (b) by investment in repurchase
    agreements (see "Portfolio Characteristics -- Repurchase Agreements"); or
    (c) by lending its portfolio securities, subject to limitations described
    elsewhere in this Statement of Additional Information. See "Portfolio
    Characteristics -- Lending of Portfolio Securities";
 
        8. Purchase oil, gas or other mineral leases, rights or royalty
           contracts or exploration or development programs, except that the
    Fund may invest in the securities of companies which invest in or sponsor
    such programs;
 
        9. Purchase securities of other investment companies, except in
           connection with a merger, consolidation, reorganization or
    acquisition of assets;
 
       10. Invest for the purpose of exercising control or management of another
           company;
 
       11. Invest in securities of any company if, to the knowledge of the Fund,
           any officer or director of the Fund or of the Investment Manager owns
    more than 1/2 of 1% of the outstanding securities of such company, and such
    officers and directors who own more than 1/2 of 1% own in the aggregate more
    than 5% of the outstanding securities of such company; and
 
       12. Write, purchase or sell puts, calls, or combinations thereof except
           options on futures contracts or options on debt securities.
 
       13. Borrow money, except that the Fund may borrow for temporary purposes
           in amounts not exceeding 5% (taken at the lower of cost or current
    value) of its total assets (not including the amount borrowed).
 
                                       18
<PAGE>
    As regards the above investment restrictions and those disclosed in the
Prospectus, if a percentage restriction is addressed at the time of investment,
a later increase or decrease in percentage resulting from a change in values of
portfolio securities or amount of total or net assets will not be considered a
violation of any of the foregoing restrictions.
 
   
    Notwithstanding any other investment policy or restriction, the Fund may
seek to achieve its investment objectives by investing all or substantially all
of its assets in another investment company having substantially the same
investment objectives and policies as the Fund.
    
 
PORTFOLIO TRANSACTIONS AND BROKERAGE
- --------------------------------------------------------------------------------
 
    Subject to the general supervision by the Board of Directors, the Investment
Manager is responsible for decisions to buy and sell securities and futures
contracts for the Fund, the selection of brokers and dealers to effect the
transactions, and the negotiation of brokerage commissions, if any. Purchases
and sales of securities on a stock exchange are effected through brokers who
charge a commission for their services. The Fund expects that the primary market
for the securities in which it intends to invest will generally be the
over-the-counter market. Securities are generally traded in the over-the-counter
market on a "net" basis with dealers acting as principal for their own accounts
without charging a stated commission, although the price of the security usually
includes a profit to the dealer. Options and futures transactions will usually
be effected through a broker and a commission will be charged. The Fund also
expects that securities will be purchased at times in underwritten offerings
where the price includes a fixed amount of compensation, generally referred to
as the underwriter's concession or discount. On occasion, the Fund may also
purchase certain money market instruments directly from an issuer, in which case
no commissions or discounts are paid. The Fund paid $95,014, $179,154 and
$301,392 in brokerage commissions during the fiscal years ended August 31, 1994,
1995 and 1996, respectively.
 
   
    The Investment Manager currently serves as investment manager to a number of
clients, including other investment companies, and may in the future act as
investment manager or adviser to others. It is the practice of the Investment
Manager to cause purchase and sale transactions to be allocated among the Fund
and others whose assets it manages in such manner as it deems equitable. In
making such allocations among the Fund and other client accounts, various
factors may be considered, including the respective investment objectives, the
relative size of portfolio holdings of the same or comparable securities, the
availability of cash for investment, the size of investment commitments
generally held and the opinions of the persons responsible for managing the
portfolios of the Fund and other client accounts. In the case of certain initial
and secondary public offerings, the Investment Manager may utilize a pro rata
allocation process based on the size of the Dean Witter Funds involved and the
number of shares available from the public offering.
    
 
    The policy of the Fund regarding purchases and sales of securities and
futures contracts for its portfolio is that primary consideration will be given
to obtaining the most favorable prices and efficient executions of transactions.
In seeking to implement the Fund's policies, the Investment Manager effects
transactions with those brokers and dealers who the Investment Manager believes
provide the most favorable prices and who are capable of providing efficient
executions. If the Investment Manager believes such prices and executions are
obtainable from more than one broker or dealer, it may give consideration to
placing portfolio transactions with those brokers and dealers who also furnish
research and other services to the Fund or the Investment Manager. Such services
may include, but are not limited to, any one or more of the following:
information as to the availability of securities for purchase or sale;
statistical or factual information or opinions pertaining to investment; wire
services; and appraisals or evaluations of portfolio securities.
 
    The information and services received by the Investment Manager from brokers
and dealers may be of benefit to the Investment Manager in the management of
accounts of some of its other clients and may not in all cases benefit the Fund
directly. While the receipt of such information and services is useful in
varying degrees and would generally reduce the amount of research or services
otherwise performed by
 
                                       19
<PAGE>
the Investment Manager and thus reduce its expenses, it is of indeterminable
value and the management fee paid to the Investment Manager is not reduced by
any amount that may be attributable to the value of such services.
 
   
    Pursuant to an order of the Securities and Exchange Commission, the Fund may
effect principal transactions in certain money market instruments with DWR. The
Fund will limit its transactions with DWR to U.S. Government and Government
Agency Securities, Bank Money Instruments (I.E., Certificates of Deposit and
Bankers' Acceptances) and Commercial Paper (not including Tax-Exempt Municipal
Paper). Such transactions will be effected with DWR only when the price
available from DWR is better than that available from other dealers. During the
fiscal years ended August 31, 1994, 1995 and 1996, the Fund did not effect any
principal transactions with DWR.
    
 
   
    Consistent with the policy described above, brokerage transactions in
securities listed on exchanges or admitted to unlisted trading privileges may be
effected through DWR and other affiliated brokers and dealers. In order for an
affiliated broker or dealer to effect portfolio transactions for the Fund, the
commissions, fees or other remuneration received by the affiliated broker or
dealer must be reasonable and fair compared to the commissions, fees or other
remuneration paid to other brokers in connection with comparable transactions
involving similar securities being purchased or sold on an exchange during a
comparable period of time. This standard would allow the affiliated broker or
dealer to receive no more than the remuneration which would be expected to be
received by an unaffiliated broker in a commensurate arm's-length transaction.
Furthermore, the Directors of the Fund, including a majority of the Directors
who are not "interested" Directors, have adopted procedures which are reasonably
designed to provide that any commissions, fees or other remuneration paid to an
affiliated broker or dealer are consistent with the foregoing standard. The Fund
does not reduce the management fee it pays to the Investment Manager by the
amount of the brokerage commissions it may pay to an affiliated broker or
dealer. During the fiscal years ended August 31, 1994, 1995 and 1996, the Fund
paid no brokerage commissions to any affiliated brokers or dealers.
    
 
   
THE DISTRIBUTOR
    
- --------------------------------------------------------------------------------
 
   
    As discussed in the Prospectus, shares of the Fund are distributed by Dean
Witter Distributors Inc. (the "Distributor"). The Distributor has entered into a
selected dealer agreement with DWR, which through its own sales organization
sells shares of the Fund. In addition, the Distributor may enter into agreements
with other selected broker-dealers. The Distributor, a Delaware corporation, is
a wholly-owned subsidiary of MSDWD. The Directors of the Fund, including a
majority of the Directors who are not, and were not at the time they voted,
interested persons of the Fund, as defined in the Act (the "Independent
Directors"), approved, at their meeting held on June 30, 1997, the current
Distribution Agreement appointing the Distributor exclusive distributor of the
Fund's shares and providing for the Distributor to bear distribution expenses
not borne by the Fund. By its terms, the Distribution Agreement has an initial
term ending April 30, 1998 and will remain in effect from year to year
thereafter if approved by the Board.
    
 
   
    The Distributor bears all expenses it may incur in providing services under
the Distribution Agreement. Such expenses include the payment of commissions for
sales of the Fund's shares and incentive compensation to account executives. The
Distributor also pays certain expenses in connection with the distribution of
the Fund's shares, including the costs of preparing, printing and distributing
advertising or promotional materials, and the costs of printing and distributing
prospectuses and supplements thereto used in connection with the offering and
sale of the Fund's shares. The Fund bears the costs of initial typesetting,
printing and distribution of prospectuses and supplements thereto to
shareholders. The Fund also bears the costs of registering the Fund and its
shares under federal securities laws and pays filing fees in accordance with
state securities laws. The Fund and the Distributor have agreed to indemnify
each other against certain liabilities, including liabilities under the
Securities Act of 1933, as amended. Under the Distribution Agreement, the
Distributor uses its best efforts in rendering services to
    
 
                                       20
<PAGE>
   
the Fund, but in the absence of willful misfeasance, bad faith, gross negligence
or reckless disregard of its obligations, the Distributor is not liable to the
Fund or any of its shareholders for any error of judgment or mistake of law or
for any act or omission or for losses sustained by the Fund or its shareholders.
    
 
   
PLAN OF DISTRIBUTION
    
 
   
    Effective July 28, 1997, the Fund has adopted a Plan of Distribution
pursuant to Rule 12b-1 under the Act (the "Plan") pursuant to which each Class,
other than Class D, pays the Distributor compensation accrued daily and payable
monthly at the following annual rates: 0.25% and 0.85% of the average daily net
assets of Class A and Class C, respectively, and, with respect to Class B, 0.75%
of the average daily net assets of Class B. The Distributor also receives the
proceeds of front-end sales charges and of contingent deferred sales charges
imposed on certain redemptions of shares, which are separate and apart from
payments made pursuant to the Plan (see "Purchase of Fund Shares" in the
Prospectus). The Distributor has informed the Fund that it and/or DWR received
approximately $2,208,000, $611,000 and $1,594,948 in front-end sales charges for
the fiscal years ended August 31, 1994, 1995 and 1996, respectively.
    
 
   
    The Distributor has informed the Fund that the entire fee payable by Class A
and a portion of the fees payable by each of Class B and Class C each year
pursuant to the Plan equal to 0.20% of the average daily net assets of Class B
and 0.25% of the average daily net assets of Class C are currently each
characterized as a "service fee" under the Rules of the Association of the
National Association of Securities Dealers, Inc. (of which the Distributor is a
member). The "service fee" is a payment made for personal service and/or the
maintenance of shareholder accounts. The remaining portion of the Plan fees
payable by a Class, if any, is characterized as an "asset-based sales charge" as
such is defined by the aforementioned Rules of the Association.
    
 
   
    The Plan was adopted by a majority vote of the Board of Directors, including
all of the Directors of the Fund who are not "interested persons" of the Fund
(as defined in the Act) and who have no direct or indirect financial interest in
the operation of the Plan (the "Independent 12b-1 Directors"), cast in person at
a meeting called for the purpose of voting on the Plan, on June 30, 1997.
    
 
   
    Under its terms, the Plan has an initial term ending April 30, 1998 and will
continue from year to year thereafter, provided such continuance is approved
annually by a vote of the Directors in the manner described above.
    
 
   
    Under the Plan and as required by Rule 12b-1, the Directors receive and
review promptly after the end of each calendar quarter a written report provided
by the Distributor of the amounts expended under the Plan and the purpose for
which such expenditures were made.
    
 
   
    The Plan was adopted in order to permit the implementation of the Fund's
method of distribution. Under this distribution method the Fund offers four
Classes of shares, each with a different distribution arrangement as set forth
in the Prospectus.
    
 
   
    With respect to Class A shares, DWR compensates its account executives by
paying them, from proceeds of the front-end sales charge, commissions for the
sale of Class A shares, currently a gross sales credit of up to 4.0% of the
amount sold (except as provided in the following sentence) and an annual
residual commission, currently a residual of up to 0.20% of the current value of
the respective accounts for which they are the account executives or dealers of
record in all cases. On orders of $1 million or more (for which no sales charge
was paid) or net asset value purchases by 401(k) plans or other
employer-sponsored plans qualified under Section 401(a) of the Internal Revenue
Code for which Dean Witter Trust Company ("DWTC") or Dean Witter Trust FSB
("DWTFSB") serves as Trustee or the 401(k) Support Services Group of DWR serves
as recordkeeper, the Investment Manager compensates DWR's account executives by
paying them, from its own funds, a gross sales credit of 1.0% of the amount
sold.
    
 
   
    With respect to Class B shares, DWR compensates its account executives by
paying them, from its own funds, commissions for the sale of Class B shares,
currently a gross sales credit of up to 4.0% of the amount sold (except as
provided in the following sentence) and an annual residual commission,
    
 
                                       21
<PAGE>
   
currently a residual of up to 0.20% of the current value of the respective
accounts for which they are the account executives of record in all cases. In
the case of retirement plans qualified under Section 401(k) of the Internal
Revenue Code and other employer-sponsored plans qualified under Section 401(a)
of the Internal Revenue Code for which DWTC or DWTFSB serves as Trustee or the
401(k) Support Services Group of DWR serves as recordkeeper, and which plans are
opened on or after July 28, 1997, DWR compensates its account executives by
paying them, from its own funds, a gross sales credit of 3.0% of the amount
sold.
    
 
   
    With respect to Class C shares, DWR compensates its account executives by
paying them, from its own funds, commissions for the sale of Class C shares,
currently a gross sales credit of up to 1.0% of the amount sold and an annual
residual commission, currently a residual of up to 0.85% of the current value of
the respective accounts for which they are the account executives of record.
    
 
   
    With respect to Class D shares other than shares held by participants in
InterCapital's mutual fund asset allocation program, the Investment Manager
compensates DWR's account executives by paying them, from its own funds,
commissions for the sale of Class D shares, currently a gross sales credit of up
to 1.0% of the amount sold. There is a chargeback of 100% of the amount paid if
the Class D shares are redeemed in the first year and a chargeback of 50% of the
amount paid if the Class D shares are redeemed in the second year after
purchase. The Investment Manager also compensates DWR's account executives by
paying them, from its own funds, an annual residual commission, currently a
residual of up to 0.10% of the current value of the respective accounts for
which they are the account executives of record (not including accounts of
participants in the InterCapital mutual fund asset allocation program).
    
 
   
    The gross sales credit is a charge which reflects commissions paid by DWR to
its account executives and DWR's Fund-associated distribution-related expenses,
including sales compensation, and overhead and other branch office
distribution-related expenses including (a) the expenses of operating DWR's
branch offices in connection with the sale of Fund shares, including lease
costs, the salaries and employee benefits of operations and sales support
personnel, utility costs, communications costs and the costs of stationery and
supplies, (b) the costs of client sales seminars, (c) travel expenses of mutual
fund sales coordinators to promote the sale of Fund shares and (d) other
expenses relating to branch promotion of Fund sales. The distribution fee that
the Distributor receives from the Fund under the Plan, in effect, offsets
distribution expenses incurred under the Plan on behalf of the Fund and, in the
case of Class B shares, opportunity costs, such as the gross sales credit and an
assumed interest charge thereon ("carrying charge"). In the Distributor's
reporting of the distribution expenses to the Fund, in the case of Class B
shares, such assumed interest (computed at the "broker's call rate") has been
calculated on the gross credit as it is reduced by amounts received by the
Distributor under the Plan and any contingent deferred sales charges received by
the Distributor upon redemption of shares of the Fund. No other interest charge
is included as a distribution expense in the Distributor's calculation of its
distribution costs for this purpose. The broker's call rate is the interest rate
charged to securities brokers on loans secured by exchange-listed securities.
    
 
   
    The Fund is authorized to reimburse expenses incurred or to be incurred in
promoting the distribution of the Fund's Class A and Class C shares and in
servicing shareholder accounts. Reimbursement will be made through payments at
the end of each month. The amount of each monthly payment may in no event exceed
an amount equal to a payment at the annual rate of 0.25%, in the case of Class
A, and 0.85%, in the case of Class C, of the average net assets of the
respective Class during the month. No interest or other financing charges, if
any, incurred on any distribution expenses on behalf of Class A and Class C will
be reimbursable under the Plan. With respect to Class A, in the case of all
expenses other than expenses representing the service fee, and, with respect to
Class C, in the case of all expenses other than expenses representing a gross
sales credit or a residual to account executives, such amounts shall be
determined at the beginning of each calendar quarter by the Directors, including
a majority of the Independent 12b-1 Directors. Expenses representing the service
fee (for Class A) or a gross sales credit or a residual to account executives
(for Class C) may be reimbursed without prior determination. In the event that
the Distributor proposes that monies shall be reimbursed for other than such
expenses,
    
 
                                       22
<PAGE>
   
then in making quarterly determinations of the amounts that may be reimbursed by
the Fund, the Distributor will provide and the Directors will review a quarterly
budget of projected distribution expenses to be incurred on behalf of the Fund,
together with a report explaining the purposes and anticipated benefits of
incurring such expenses. The Directors will determine which particular expenses,
and the portions thereof, that may be borne by the Fund, and in making such a
determination shall consider the scope of the Distributor's commitment to
promoting the distribution of the Fund's Class A and Class C shares.
    
 
   
    At any given time, the expenses of distributing shares of the Fund may be
more or less than the total of (i) the payments made by the Fund pursuant to the
Plan and (ii) the proceeds of contingent deferred sales charges paid by
investors upon redemption of shares. Because there is no requirement under the
Plan that the Distributor be reimbursed for all distribution expenses with
respect to Class B shares or any requirement that the Plan be continued from
year to year, this excess amount does not constitute a liability of the Fund.
Although there is no legal obligation for the Fund to pay expenses incurred in
excess of payments made to the Distributor under the Plan and the proceeds of
contingent deferred sales charges paid by investors upon redemption of shares,
if for any reason the Plan is terminated, the Directors will consider at that
time the manner in which to treat such expenses. Any cumulative expenses
incurred, but not yet recovered through distribution fees or contingent deferred
sales charges, may or may not be recovered through future distribution fees or
contingent deferred sales charges.
    
 
   
    No interested person of the Fund nor any Director of the Fund who is not an
interested person of the Fund, as defined in the Act, has any direct financial
interest in the operation of the Plan except to the extent that the Distributor,
InterCapital, DWR, DWSC or certain of their employees may be deemed to have such
an interest as a result of benefits derived from the successful operation of the
Plan or as a result of receiving a portion of the amounts expended thereunder by
the Fund.
    
 
   
    The Plan may not be amended to increase materially the amount to be spent
for the services described therein without approval by the shareholders of the
affected Class or Classes of the Fund, and all material amendments to the Plan
must also be approved by the Directors in the manner described above. The Plan
may be terminated at any time, without payment of any penalty, by vote of a
majority of the Independent 12b-1 Directors or by a vote of a majority of the
outstanding voting securities of the Fund (as defined in the Act) on not more
than thirty days' written notice to any other party to the Plan. So long as the
Plan is in effect, the election and nomination of Independent 12b-1 Directors
shall be committed to the discretion of the Independent 12b-1 Directors.
    
 
   
DETERMINATION OF NET ASSET VALUE
    
- --------------------------------------------------------------------------------
 
   
    As discussed in the Prospectus, the net asset value per share for each Class
of shares of the Fund is determined once daily at 4:00 p.m., New York time (or,
on days when the New York Stock Exchange closes prior to 4:00 p.m., at such
earlier time) on each day that the New York Stock Exchange is open. The New York
Stock Exchange currently observes the following holidays: New Year's Day;
President's Day; Good Friday; Memorial Day; Independence Day; Labor Day;
Thanksgiving Day; and Christmas Day.
    
 
   
PURCHASE OF FUND SHARES
    
- --------------------------------------------------------------------------------
 
   
    As discussed in the Prospectus, the Fund offers four Classes of shares as
follows:
    
 
   
INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES
    
 
   
    Class A shares are sold to investors with an initial sales charge that
declines to zero for larger purchases; however, Class A shares sold without an
initial sales charge are subject to a contingent deferred sales charge ("CDSC")
of 1.0% if redeemed within one year of purchase, except in the circumstances
discussed in the Prospectus.
    
 
                                       23
<PAGE>
   
    RIGHT OF ACCUMULATION.  As discussed in the Prospectus, investors may
combine the current value of shares purchased in separate transactions for
purposes of benefitting from the reduced sales charges available for purchases
of shares of the Fund totalling at least $25,000 in net asset value. For
example, if any person or entity who qualifies for this privilege holds Class A
shares of the Fund and/or other Dean Witter Funds that are multiple class funds
("Dean Witter Multi-Class Funds") or shares of other Dean Witter Funds sold with
a front-end sales charge purchased at a price including a front-end sales charge
having a current value of $5,000, and purchases $20,000 of additional shares of
the Fund, the sales charge applicable to the $20,000 purchase would be 4.0% of
the offering price.
    
 
   
    The Distributor must be notified by the selected broker-dealer or the
shareholder at the time a purchase order is placed that the purchase qualifies
for the reduced charge under the Right of Accumulation. Similar notification
must be made in writing by the selected broker-dealer or shareholder when such
an order is placed by mail. The reduced sales charge will not be granted if: (a)
such notification is not furnished at the time of the order; or (b) a review of
the records of the Distributor or Dean Witter Trust Company (the "Transfer
Agent") fails to confirm the investor's represented holdings.
    
 
   
    LETTER OF INTENT.  As discussed in the Prospectus, reduced sales charges are
available to investors who enter into a written Letter of Intent providing for
the purchase, within a thirteen-month period, of Class A shares of the Fund from
the Distributor or from a single Selected Broker-Dealer.
    
 
   
    A Letter of Intent permits an investor to establish a total investment goal
to be achieved by any number of purchases over a thirteen-month period. Each
purchase of Class A shares made during the period will receive the reduced sales
commission applicable to the amount represented by the goal, as if it were a
single purchase. A number of shares equal in value to 5% of the dollar amount of
the Letter of Intent will be held in escrow by the Transfer Agent, in the name
of the shareholder. The initial purchase under a Letter of Intent must be equal
to at least 5% of the stated investment goal.
    
 
   
    The Letter of Intent does not obligate the investor to purchase, nor the
Fund to sell, the indicated amount. In the event the Letter of Intent goal is
not achieved within the thirteen-month period, the investor is required to pay
the difference between the sales charge otherwise applicable to the purchases
made during this period and sales charges actually paid. Such payment may be
made directly to the Distributor or, if not paid, the Distributor is authorized
by the shareholder to liquidate a sufficient number of his or her escrowed
shares to obtain such difference.
    
 
   
    If the goal is exceeded and purchases pass the next sales charge level, the
sales charge on the entire amount of the purchase that results in passing that
level and on subsequent purchases will be subject to further reduced sales
charges in the same manner as set forth above under "Right of Accumulation," but
there will be no retroactive reduction of sales charges on previous purchases.
For the purpose of determining whether the investor is entitled to a further
reduced sales charge applicable to purchases at or above a sales charge level
which exceeds the stated goal of a Letter of Intent, the cumulative current net
asset value of any shares owned by the investor in any other Dean Witter Funds
held by the shareholder which were previously purchased at a price including a
front-end sales charge (including shares of the Fund and other Dean Witter Funds
acquired in exchange for those shares, and including in each case shares
acquired through reinvestment of dividends and distributions) will be added to
the cost or net asset value of shares of the Fund owned by the investor.
However, shares of "Exchange Funds" (see "Shareholder Services--Exchange
Privilege") and the purchase of shares of other Dean Witter Funds will not be
included in determining whether the stated goal of a Letter of Intent has been
reached.
    
 
   
    At any time while a Letter of Intent is in effect, a shareholder may, by
written notice to the Distributor, increase the amount of the stated goal. In
that event, only shares purchased during the previous 90-day period and still
owned by the shareholder will be included in the new sales charge reduction. The
5% escrow and minimum purchase requirements will be applicable to the new stated
goal. Investors electing to purchase shares of the Fund pursuant to a Letter of
Intent should carefully read such Letter of Intent.
    
 
                                       24
<PAGE>
   
CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE--CLASS B SHARES
    
 
   
    Class B shares are sold without an initial sales charge but are subject to a
CDSC payable upon most redemptions within six years after purchase. As stated in
the Prospectus, a CDSC will be imposed on any redemption by an investor if after
such redemption the current value of the investor's Class B shares of the Fund
is less than the dollar amount of all payments by the shareholder for the
purchase of Class B shares during the preceding six years (or, in the case of
shares held by certain employer-sponsored benefit plans, three years). However,
no CDSC will be imposed to the extent that the net asset value of the shares
redeemed does not exceed: (a) the current net asset value of shares purchased
more than six years (or, in the case of shares held by certain
employer-sponsored benefit plans, three years) prior to the redemption, plus (b)
the current net asset value of shares purchased through reinvestment of
dividends or distributions of the Fund or another Dean Witter Fund (see
"Shareholder Services-- Targeted Dividends"), plus (c) the current net asset
value of shares acquired in exchange for (i) shares of Dean Witter front-end
sales charge funds, or (ii) shares of other Dean Witter Funds for which shares
of front-end sales charge funds have been exchanged (see "Shareholder
Services--Exchange Privilege"), plus (d) increases in the net asset value of the
investor's shares above the total amount of payments for the purchase of Fund
shares made during the preceding six (three) years. The CDSC will be paid to the
Distributor.
    
 
   
    In determining the applicability of the CDSC to each redemption, the amount
which represents an increase in the net asset value of the investor's shares
above the amount of the total payments for the purchase of shares within the
last six years (or, in the case of shares held by certain employer-sponsored
benefit plans, three years) will be redeemed first. In the event the redemption
amount exceeds such increase in value, the next portion of the amount redeemed
will be the amount which represents the net asset value of the investor's shares
purchased more than six (three) years prior to the redemption and/or shares
purchased through reinvestment of dividends or distributions and/or shares
acquired in exchange for shares of Dean Witter front-end sales charge funds, or
for shares of other Dean Witter funds for which shares of front-end sales charge
funds have been exchanged. A portion of the amount redeemed which exceeds an
amount which represents both such increase in value and the value of shares
purchased more than six years (or, in the case of shares held by certain
employer-sponsored benefit plans, three years) prior to the redemption and/or
shares purchased through reinvestment of dividends or distributions and/or
shares acquired in the above-described exchanges will be subject to a CDSC.
    
 
   
    The amount of the CDSC, if any, will vary depending on the number of years
from the time of payment for the purchase of Class B shares of the Fund until
the time of redemption of such shares. For purposes of determining the number of
years from the time of any payment for the purchase of shares, all payments made
during a month will be aggregated and deemed to have been made on the last day
of the month. The following table sets forth the rates of the CDSC applicable to
most Class B shares of the Fund:

    The following table sets forth the rates of the CDSC applicable to Class B
shares of the Fund held by 401(k) plans or other employer-sponsored plans
qualified under Section 401(a) of the Internal Revenue Code for which DWTC or

    In determining the rate of the CDSC, it will be assumed that a redemption is
made of shares held by the investor for the longest period of time within the
applicable six-year or three-year period. This will result in any such CDSC
being imposed at the lowest possible rate. The CDSC will be imposed, in
accordance with the table shown above, on any redemptions within six years (or,
in the case of shares held by certain employer-sponsored benefit plans, three
years) of purchase which are in excess of these amounts and which redemptions do
not qualify for waiver of the CDSC, as described in the Prospectus.
    
 
   
LEVEL LOAD ALTERNATIVE--CLASS C SHARES
    
 
   
    Class C shares are sold without a sales charge but are subject to a CDSC of
1.0% on most redemptions made within one year after purchase, except in the
circumstances discussed in the Prospectus.
    
 
   
NO LOAD ALTERNATIVE--CLASS D SHARES
    
 
   
    Class D shares are offered without any sales charge on purchase or
redemption. Class D shares are offered only to those persons meeting the
qualifications set forth in the Prospectus.
    
 
SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 
    Upon the purchase of shares of the Fund, a Shareholder Investment Account is
opened for the investor on the books of the Fund, maintained by the Transfer
Agent. This is an open account in which shares owned by the investor are
credited by the Transfer Agent in lieu of issuance of a stock certificate. If a
stock certificate is desired, it must be requested in writing for each
transaction. Certificates are issued only for full shares and may be redeposited
in the account at any time. There is no charge to the investor for issuance of a
certificate. Whenever a shareholder instituted transaction takes place in the
Shareholder Investment Account, the shareholder will be mailed a confirmation of
the transaction from the Fund or from DWR or other selected broker-dealer.
 
   
    AUTOMATIC INVESTMENT OF DIVIDENDS AND DISTRIBUTIONS.  As stated in the
Prospectus, all income dividends and capital gains distributions are
automatically paid in full and fractional shares of the applicable Class of the
Fund, unless the shareholder requests that they be paid in cash. Each purchase
of shares of the Fund is made upon the condition that the Transfer Agent is
thereby automatically appointed as agent of the investor to receive all
dividends and capital gains distributions on shares owned by the investor. Such
dividends and distributions will be paid, at the net asset value per share, in
shares of the applicable Class of the Fund (or in cash if the shareholder so
requests) as of the close of business on the record date. At any time an
investor may request the Transfer Agent, in writing, to have subsequent
dividends and/or capital gains distributions paid to him or her in cash rather
than shares. To assure sufficient time to process the change, such request
should be received by the Transfer Agent at least five business days prior to
the record date of the dividend or distribution. In the case of recently
purchased shares for which registration instructions have not been received on
the record date, cash payments will be made to DWR or other selected
broker-dealer, and will be forwarded to the shareholder, upon the receipt of
proper instructions.
    
 
   
    TARGETED DIVIDENDS.-SM-  In states where it is legally permissible,
shareholders may also have all income dividends and capital gains distributions
automatically invested in shares of any Class of an
    
 
                                       26
<PAGE>
   
open-end Dean Witter Fund other than Dean Witter High Yield Securities Inc. or
in another Class of Dean Witter High Yield Securities Inc. Such investment will
be made as described above for automatic investment in shares of the applicable
Class of the Fund, at the net asset value per share of the selected Dean Witter
Fund as of the close of business on the payment date of the dividend or
distribution and will begin to earn dividends, if any, in the selected Dean
Witter Fund the next business day. To participate in the Targeted Dividends
program, shareholders should contact their DWR or other selected broker-dealer
account executive or the Transfer Agent. Shareholders of the Fund must be
shareholders of the selected Class of the Dean Witter Fund targeted to receive
investments from dividends at the time they enter the Targeted Dividends
program. Investors should review the prospectus of the targeted Dean Witter Fund
before entering the program.
    
 
   
    EASYINVEST.-SM-  Shareholders may subscribe to EasyInvest, an automatic
purchase plan which provides for any amount from $100 to $5,000 to be
transferred automatically from a checking or savings account or following
redemption of shares of a Dean Witter money market fund, on a semi-monthly,
monthly or quarterly basis, to the Transfer Agent for investment in shares of
the Fund. Shares purchased through EasyInvest will be added to the shareholder's
existing account at the net asset value calculated the same business day the
transfer of funds is effected. For further information or to subscribe to
EasyInvest, shareholders should contact their DWR or other selected
broker-dealer account executive or the Transfer Agent.
    
 
   
    INVESTMENT OF DISTRIBUTIONS RECEIVED IN CASH.  As discussed in the
Prospectus, 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 net asset value, without the imposition of a CDSC
upon redemption, by returning the check or the proceeds to the Transfer Agent
within thirty days after the payment date. If the shareholder returns the
proceeds of a dividend or distribution, such funds must be accompanied by a
signed statement indicating that the proceeds constitute a dividend or
distribution to be invested. Such investment will be made at the net asset value
per share next determined after receipt of the check or the proceeds by the
Transfer Agent.
    
 
   
    SYSTEMATIC WITHDRAWAL PLAN.  As discussed in the Prospectus, a systematic
withdrawal plan (the "Withdrawal Plan") is available for shareholders who own or
purchase shares of the Fund having a minimum value of $10,000 based upon the
then current offering price. The 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 (net of any applicable CDSC) to the shareholder will be the designated
monthly or quarterly amount.
    
 
   
    The Transfer Agent acts as agent for the shareholder in tendering to the
Fund for redemption sufficient full and fractional shares to provide the amount
of the periodic withdrawal payment designated in the application. The shares
will be redeemed at their net asset value determined, at the shareholder's
option, on the tenth or twenty-fifth day (or next following business day) of the
relevant month or quarter and normally a check for the proceeds will be mailed
by the Transfer Agent, or amounts credited to a shareholder's DWR or other
selected broker-dealer brokerage account, within five business days after the
date of redemption. The Withdrawal Plan may be terminated at any time by the
Fund.
    
 
   
    Withdrawal Plan payments should not be considered as dividends, yields or
income. If periodic withdrawal plan payments continuously exceed net investment
income and net capital gains, the shareholder's original investment will be
correspondingly reduced and ultimately exhausted.
    
 
   
    Each withdrawal constitutes a redemption of shares and any gain or loss
realized must be recognized for federal income tax purposes. Although the
shareholder may make additional investments of $2,500 or more under the
Withdrawal Plan, withdrawals made concurrently with purchases of additional
shares may be inadvisable because of sales charges which may be applicable to
purchases or redemptions of shares (see "Purchase of Fund Shares").
    
 
                                       27
<PAGE>
   
    Any shareholder who wishes to have payments under the Withdrawal Plan made
to a third party or sent to an address other than the one listed on the account
must send complete written instructions to the Transfer Agent to enroll in the
Withdrawal Plan. The shareholder's signature on such instructions must be
guaranteed by an eligible guarantor acceptable to the Transfer Agent
(shareholders should contact the Transfer Agent for a determination as to
whether a particular institution is an eligible guarantor). A shareholder may,
at any time, change the amount and interval of withdrawal payments through his
or her account executive or by written notification to the Transfer Agent. In
addition, the party and/or the address to which checks are mailed may be changed
by written notification to the Transfer Agent, with signature guarantees
required in the manner described above. The shareholder may also terminate the
Withdrawal Plan at any time by written notice to the Transfer Agent. In the
event of such termination, the account will be continued as a regular
shareholder investment account. The shareholder may also redeem all or part of
the shares held in the Withdrawal Plan account (see "Redemptions and
Repurchases" in the Prospectus) at any time.
    
 
   
    DIRECT INVESTMENTS THROUGH TRANSFER AGENT.  As discussed in the Prospectus,
shareholders may make additional investments in any Class of shares of the Fund
for which they qualify at any time by sending a check in any amount, not less
than $100, payable to Dean Witter High Yield Securities Inc., and indicating the
selected Class, directly to the Fund's Transfer Agent. In the case of Class A
shares, after deduction of any applicable sales charge, the balance will be
applied to the purchase of Fund shares, and, in the case of shares of the other
Classes, the entire amount will be applied to the purchase of Fund shares, at
the net asset value per share next computed after receipt of the check or
purchase payment by the Transfer Agent. The shares so purchased will be credited
to the investor's account.
    
 
   
EXCHANGE PRIVILEGE
    
 
   
    As discussed in the Prospectus, the Fund makes available to its shareholders
an Exchange Privilege whereby shareholders of each Class of shares of the Fund
may exchange their shares for shares of the same Class of shares of any other
Dean Witter Multi-Class Fund without the imposition of any exchange fee. Shares
may also be exchanged for shares of any of the following funds: Dean Witter
Short-Term U.S. Treasury Trust, Dean Witter Limited Term Municipal Trust, Dean
Witter Short-Term Bond Fund, Dean Witter Intermediate Term U.S. Treasury Trust
and five Dean Witter Funds which are money market funds (the foregoing nine
funds are hereinafter referred to as the "Exchange Funds"). Class A shares may
also be exchanged for shares of Dean Witter Multi-State Municipal Series Trust
and Dean Witter Hawaii Municipal Trust, which are Dean Witter Funds sold with a
front-end sales charge ("FSC Funds"). Class B shares may also be exchanged for
shares of Dean Witter Global Short-Term Income Fund Inc., Dean Witter High
Income Securities and Dean Witter National Municipal Trust, which are Dean
Witter Funds offered with a CDSC ("CDSC Funds"). Exchanges may be made after the
shares of the Fund acquired by purchase (not by exchange or dividend
reinvestment) have been held for thirty days. There is no waiting period for
exchanges of shares acquired by exchange or dividend reinvestment. An exchange
will be treated for federal income tax purposes the same as a repurchase or
redemption of shares, on which the shareholder may realize a capital gain or
loss.
    
 
   
    Any new account established through the Exchange Privilege will have the
same registration and cash dividend or dividend reinvestment plan as the present
account, unless the Transfer Agent receives written notification to the
contrary. For telephone exchanges, the exact registration of the existing
account and the account number must be provided.
    
 
   
    Any shares held in certificate form cannot be exchanged but must be
forwarded to the Transfer Agent and deposited into the shareholder's account
before being eligible for exchange. (Certificates mailed in for deposit should
not be endorsed.)
    
 
   
    As described below, and in the Prospectus under the caption "Purchase of
Fund Shares," a CDSC may be imposed upon a redemption, depending on a number of
factors, including the number of years from the time of purchase until the time
of redemption or exchange ("holding period"). When shares of a Dean Witter
Multi-Class Fund or any CDSC Fund are exchanged for shares of an Exchange Fund,
the exchange is executed at no charge to the shareholder, without the imposition
of the CDSC at the time of the exchange. During the period of time the
shareholder remains in the Exchange Fund (calculated from
    
 
                                       28
<PAGE>
   
the last day of the month in which the Exchange Fund shares were acquired), the
holding period or "year since purchase payment made" is frozen. When shares are
redeemed out of the Exchange Fund, they will be subject to a CDSC which would be
based upon the period of time the shareholder held shares in a Dean Witter
Multi-Class Fund or in a CDSC Fund. However, in the case of shares exchanged
into an Exchange Fund on or after April 23, 1990, upon a redemption of shares
which results in a CDSC being imposed, a credit (not to exceed the amount of the
CDSC) will be given in an amount equal to the Exchange Fund 12b-1 distribution
fees incurred on or after that date which are attributable to those shares.
Shareholders acquiring shares of an Exchange Fund pursuant to this exchange
privilege may exchange those shares back into a Dean Witter Multi-Class Fund or
a CDSC Fund from the Exchange Fund, with no CDSC being imposed on such exchange.
The holding period previously frozen when shares were first exchanged for shares
of the Exchange Fund resumes on the last day of the month in which shares of a
Dean Witter Multi-Class Fund or of a CDSC Fund are reacquired. A CDSC is imposed
only upon an ultimate redemption, based upon the time (calculated as described
above) the shareholder was invested in a Dean Witter Multi-Class Fund or in a
CDSC Fund. In the case of exchanges of Class A shares which are subject to a
CDSC, the holding period also includes the time (calculated as described above)
the shareholder was invested in a FSC Fund.
    
 
   
    When shares initially purchased in a Dean Witter Multi-Class Fund or in a
CDSC Fund are exchanged for shares of a Dean Witter Multi-Class Fund, shares of
a CDSC Fund, shares of a FSC Fund, or shares of an Exchange Fund, the date of
purchase of the shares of the fund exchanged into, for purposes of the CDSC upon
redemption, will be the last day of the month in which the shares being
exchanged were originally purchased. In allocating the purchase payments between
funds for purposes of the CDSC, the amount which represents the current net
asset value of shares at the time of the exchange which were (i) purchased more
than one, three or six years (depending on the CDSC schedule applicable to the
shares) prior to the exchange, (ii) originally acquired through reinvestment of
dividends or distributions and (iii) acquired in exchange for shares of FSC
Funds, or for shares of other Dean Witter Funds for which shares of FSC Funds
have been exchanged (all such shares called "Free Shares"), will be exchanged
first. After an exchange, all dividends earned on shares in an Exchange Fund
will be considered Free Shares. If the exchanged amount exceeds the value of
such Free Shares, an exchange is made, on a block-by-block basis, of non-Free
Shares held for the longest period of time (except that, with respect to Class B
shares, if shares held for identical periods of time but subject to different
CDSC schedules are held in the same Exchange Privilege account, the shares of
that block that are subject to a lower CDSC rate will be exchanged prior to the
shares of that block that are subject to a higher CDSC rate). Shares equal to
any appreciation in the value of non-Free Shares exchanged will be treated as
Free Shares, and the amount of the purchase payments for the non-Free Shares of
the fund exchanged into will be equal to the lesser of (a) the purchase payments
for, or (b) the current net asset value of, the exchanged non-Free Shares. If an
exchange between funds would result in exchange of only part of a particular
block of non-Free Shares, then shares equal to any appreciation in the value of
the block (up to the amount of the exchange) will be treated as Free Shares and
exchanged first, and the purchase payment for that block will be allocated on a
pro rata basis between the non-Free Shares of that block to be retained and the
non-Free Shares to be exchanged. The prorated amount of such purchase payment
attributable to the retained non-Free Shares will remain as the purchase payment
for such shares, and the amount of purchase payment for the exchanged non-Free
Shares will be equal to the lesser of (a) the prorated amount of the purchase
payment for, or (b) the current net asset value of, those exchanged non-Free
Shares. Based upon the procedures described in the Prospectus under the caption
"Purchase of Fund Shares," any applicable CDSC will be imposed upon the ultimate
redemption of shares of any fund, regardless of the number of exchanges since
those shares were originally purchased.
    
 
   
    With respect to the redemption or repurchase of shares of the Fund, the
application of proceeds to the purchase of new shares in the Fund or any other
of the funds and the general administration of the Exchange Privilege, the
Transfer Agent acts as agent for the Distributor and for the shareholder's
    
 
                                       29
<PAGE>
   
selected broker-dealer, if any, in the performance of such functions. With
respect to exchanges, redemptions or repurchases, the Transfer Agent shall be
liable for its own negligence and not for the default or negligence of its
correspondents or for losses in transit. The Fund shall not be liable for any
default or negligence of the Transfer Agent, the Distributor or any selected
broker-dealer.
    
 
   
    The Distributor and any selected broker-dealer have authorized and appointed
the Transfer Agent to act as their agent in connection with the application of
proceeds of any redemption of Fund shares to the purchase of shares of any other
fund and the general administration of the Exchange Privilege. No commission or
discounts will be paid to the Distributor or any Dealer for any transactions
pursuant to this Exchange Privilege.
    
 
   
    Exchanges are subject to the minimum investment requirement and any other
conditions imposed by each fund. (The minimum initial investment for the
Exchange Privilege account of each Class is $5,000 for Dean Witter Liquid Asset
Fund Inc., Dean Witter Tax-Free Daily Income Trust, Dean Witter New York
Municipal Money Market Trust and Dean Witter California Tax-Free Daily Income
Trust although those funds may, at their discretion, accept initial investments
of as low as $1,000. The minimum initial investment for the Exchange Privilege
account of each Class is $10,000 for Dean Witter Short-Term U.S. Treasury Trust,
although that fund may, at its discretion, accept initial investments of as low
as $5,000. The minimum initial investment for the Exchange Privilege account of
each Class is $5,000 for Dean Witter Special Value Fund. The minimum initial
investment for the Exchange Privilege account of each Class of all other Dean
Witter Funds for which the Exchange Privilege is available is $1,000.) Upon
exchange into an Exchange Fund the shares of that fund will be held in a special
Exchange Privilege Account separately from accounts of those shareholders who
have acquired their shares directly from that fund. As a result, certain
services normally available to shareholders of those funds, including the check
writing feature, will not be available for funds held in that account.
    
 
   
    The Fund and each of the other Dean Witter Funds may limit the number of
times this Exchange Privilege may be exercised by any investor within a
specified period of time. Also, the Exchange Privilege may be terminated or
revised at any time by the Fund and/or any of the Dean Witter Funds for which
shares of the Fund have been exchanged, upon such notice as may be required by
applicable regulatory authorities (presently sixty days' prior written notice
for termination or material revision), provided that six months' prior written
notice of termination will be given to the shareholders who hold shares of
Exchange Funds pursuant to this Exchange Privilege, and provided further that
the Exchange Privilege may be terminated or materially revised without notice at
times (a) when the New York Stock Exchange is closed for other than customary
weekends and holidays, (b) when trading on that Exchange is restricted, (c) when
an emergency exists as a result of which disposal by the Fund of securities
owned by it is not reasonably practicable or it is not reasonably practicable
for the Fund fairly to determine the value of its net assets, (d) during any
other period when the Securities and Exchange Commission by order so permits
(provided that applicable rules and regulations of the Securities and Exchange
Commission shall govern as to whether the conditions prescribed in (b) or (c)
exist), or (e) if the Fund would be unable to invest amounts effectively in
accordance with its investment objective(s), policies and restrictions.
    
 
    For further information regarding the Exchange Privilege, shareholders
should contact their DWR or other selected broker-dealer or the Transfer Agent.
 
REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 
   
    REDEMPTION.  As stated in the Prospectus, shares of each Class of the Fund
can be redeemed for cash at any time at the net asset value per share next
determined; however, such redemption proceeds will be reduced by the amount of
any applicable CDSC. If shares are held in a shareholder's account without a
share certificate, a written request for redemption to the Fund's Transfer Agent
at P.O. Box 983, Jersey City, NJ 07303 is required. If certificates are held by
the shareholder, the shares may be redeemed by surrendering the certificates
with a written request for redemption. The share certificate, or an accompanying
stock power, and the request for redemption, must be signed by the shareholder
or shareholders exactly as the shares are registered. Each request for
redemption, whether or not accompanied by a share certificate, must be sent to
the Fund's Transfer Agent, which will redeem the shares at
    
 
                                       30
<PAGE>
   
their net asset value next computed (see "Purchase of Fund Shares" in the
Prospectus) after it receives the request, and certificate, if any, in good
order. Any redemption request received after such computation will be redeemed
at the next determined net asset value.
    
 
   
    Whether certificates are held by the shareholder or shares are held in a
shareholder's account, if the proceeds are to be paid to any person other than
the record owner, or if the proceeds are to be paid to a corporation (other than
the Distributor or a selected broker-dealer for the account of the shareholder),
partnership, trust or fiduciary, or sent to the shareholder at an address other
than the registered address, signatures must be guaranteed by an eligible
guarantor acceptable to the Transfer Agent (shareholders should contact the
Transfer Agent for a determination as to whether a particular Institution is
such an eligible guarantor). A stock power may be obtained from any dealer or
commercial bank. The Fund may change the signature guarantee requirements from
time to time upon notice to shareholders, which may be by means of a new
prospectus.
    
 
   
    REPURCHASE.  As stated in the Prospectus, DWR and other selected
broker-dealers are authorized to repurchase shares represented by a share
certificate which is delivered to any of their offices. Shares held in a
shareholder's account without a share certificate may also be repurchased by DWR
and other selected broker-dealers upon the telephonic request of the
shareholder. The repurchase price is the net asset value next computed after
such purchase order is received by DWR or other selected broker-dealer reduced
by any applicable CDSC.
    
 
   
    PAYMENT FOR SHARES REDEEMED OR REPURCHASED.  As discussed in the Prospectus,
payment for shares of any Class presented for repurchase or redemption will be
made by check within seven days after receipt by the Transfer Agent of the
certificate and/or written request in good order. The term good order means that
the share certificate, if any, and request for redemption are properly signed,
accompanied by any documentation required by the Transfer Agent, and bear
signature guarantees when required by the Fund or the Transfer Agent. Such
payment may be postponed or the right of redemption suspended at times (a) when
the New York Stock Exchange is closed for other than customary weekends and
holidays, (b) when trading on that Exchange is restricted, (c) when an emergency
exists as a result of which disposal by the Fund of securities owned by it is
not reasonably practicable or it is not reasonably practicable for the Fund
fairly to determine the value of its net assets, or (d) during any other period
when the Securities and Exchange Commission by order so permits; provided that
applicable rules and regulations of the Securities and Exchange Commission shall
govern as to whether the conditions prescribed in (b) or (c) exist. If the
shares to be redeemed have recently been purchased by check (including a
certificate or bank cashier's check), payment of redemption proceeds may be
delayed for the minimum time needed to verify that the check used for investment
has been honored (not more than fifteen days from the time of receipt of the
check by the Transfer Agent). Shareholders maintaining margin accounts with DWR
or another selected broker-dealer are referred to their account executive
regarding restrictions on redemption of shares of the Fund pledged in the margin
account.
    
 
   
    TRANSFERS OF SHARES.  In the event a shareholder requests a transfer of any
shares to a new registration, such shares will be transferred without sales
charge at the time of transfer. With regard to the status of shares which are
either subject to the CDSC or free of such charge (and with regard to the length
of time shares subject to the charge have been held), any transfer involving
less than all the shares in an account will be made on a pro rata basis (that
is, by transferring shares in the same proportion that the transferred shares
bear to the total shares in the account immediately prior to the transfer). The
transferred shares will continue to be subject to any applicable CDSC as if they
had not been so transferred.
    
 
   
    REINSTATEMENT PRIVILEGE.  As described in the Prospectus, a shareholder who
has had his or her shares redeemed or repurchased and has not previously
exercised this reinstatement privilege may, within 35 days after the date of the
redemption or repurchase, reinstate any portion or all of the proceeds of such
redemption or repurchase in shares of the Fund in the same Class at the net
asset value next determined after a reinstatement request, together with such
proceeds, is received by the Transfer Agent.
    
 
    Exercise of the reinstatement privilege will not affect the federal income
tax treatment of any gain or loss realized upon the redemption or repurchase,
except that if the redemption or repurchase resulted in
 
                                       31
<PAGE>
   
a loss and reinstatement is made in shares of the Fund, some or all of the loss,
depending on the amount reinstated, will not be allowed as a deduction for
federal income tax purposes but will be applied to adjust the cost basis of the
shares acquired upon reinstatement.
    
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
    As discussed in the Prospectus, the Fund will determine either to distribute
or to retain all or part of any net long-term capital gains in any year for
reinvestment. If any such gains are retained, the Fund will pay federal income
tax thereon, and will notify shareholders that following an election by the
Fund, the shareholders will be required to include such undistributed gains in
determining their taxable income and may claim their share of the tax paid by
the Fund as a credit against their individual federal income tax.
 
    In computing net investment income, the Fund will not amortize premiums or
accrue discounts on fixed-income securities in the portfolio, except those
original issue discounts for which amortization is required for federal income
tax purposes. Additionally, with respect to market discounts on tax-exempt bonds
issued after July 18, 1984, and all bonds purchased after April 30, 1993, a
portion of any capital gain realized upon disposition may be re-characterized as
taxable ordinary income in accordance with the provisions of the Internal
Revenue Code. Realized gains and losses on security transactions are determined
on the identified cost method. Dividend income is recorded on the ex-dividend
date.
 
   
    Gains or losses on the sales of securities by the Fund will be long-term
capital gains or losses if the securities have been held by the Fund for more
than twelve months. Gains or losses on the sale of securities held for twelve
months or less will be short-term capital gains or losses. In determining
amounts to be distributed, capital gains will be offset by any capital loss
carryovers incurred in prior years.
    
 
    Any dividend or capital gains distribution received by a shareholder from an
investment company will have the effect of reducing the net asset value of the
shareholder's stock in that company by the exact amount of the dividend or
capital gains distribution. Furthermore, capital gains distributions and some
portion of the dividends are subject to federal income taxes. If the net asset
value of the shares should be reduced below a shareholder's cost as a result of
the payment of dividends or realized long-term capital gains, such payment would
be in part a return of the shareholder's investment to the extent of such
reduction below the shareholder's cost, but nonetheless would be taxable to the
shareholder. Therefore, an investor should consider the tax implications of
purchasing Fund shares immediately prior to a distribution record date.
 
    Shareholders should consult their attorneys or tax advisers regarding
specific questions as to state or local taxes and as to the applicability of the
foregoing to their current federal tax situation.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
   
    As discussed in the Prospectus, 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.
    
 
   
    Prior to July 28, 1997, the Fund offered only one Class of shares. Because
the distribution arrangement for Class A most closely resembles the distribution
arrangement applicable prior to the implementation of multiple classes (i.e.,
Class A is sold with a front-end sales charge), historical performance
information has been restated to reflect the actual maximum sales charge
applicable to Class A (i.e., 4.25%) as compared to the 5.5% sales charge in
effect prior to July 28, 1997. In addition, because all shares of the Fund held
prior to July 28, 1997 have been designated Class D shares, the Fund's
historical performance has also been restated to reflect the absence of any
sales charge in the case of Class D shares. In addition, Class A shares are now
subject to an ongoing 12b-1 fee which is not reflected in the restated
performance for that Class and would reduce the performance quoted below.
    
 
                                       32
<PAGE>
   
Following the restated performance information is the actual performance of the
Fund as of its last fiscal year (prior to the implementation of multiple
classes) without taking into effect the new fee and sales charge structure.
    
 
   
    Yield is calculated for any 30-day period as follows: the amount of interest
and/or dividend income for each security in the Fund's portfolio is determined
in accordance with regulatory requirements; the total for the entire portfolio
constitutes the Fund's gross income for the period. Expenses accrued during the
period are subtracted to arrive at "net investment income" of each Class. The
resulting amount is divided by the product of the maximum offering price per
share on the last day of the period multiplied by the average number of shares
of the applicable Class outstanding during the period that were entitled to
dividends. This amount is added to 1 and raised to the sixth power. 1 is then
subtracted from the result and the difference is multiplied by 2 to arrive at
the annualized yield. For the 30-day period ended August 31, 1996, the Fund's
restated yield for the Class A and Class D shares, calculated pursuant to this
formula was 11.88% and 12.43%, respectively.
    
 
   
    The Fund's "average annual total return" represents an annualization of the
Fund's total return over a particular period and is computed by finding the
annual percentage rate which will result in the ending redeemable value of a
hypothetical $1,000 investment made at the beginning of a one, five or ten year
period, or for the period from the date of commencement of the Fund's
operations, if shorter than any of the foregoing. The ending redeemable value is
reduced by any CDSC at the end of the one, five or ten year or other period. For
the purpose of this calculation, it is assumed that all dividends and
distributions are reinvested. The formula for computing the average annual total
return involves a percentage obtained by dividing the ending redeemable value by
the amount of the initial investment, taking a root of the quotient (where the
root is equivalent to the number of years in the period) and subtracting 1 from
the result. The restated average annual total returns of the Class A and Class D
shares of the Fund for the year ended August 31, 1996 were 6.35% and 11.07%,
respectively; for the five years ended August 31, 1996 were 14.77% and 15.77%,
respectively; and for the ten years ended August 31, 1996 were 6.06% and 6.53%,
respectively.
    
 
   
    In addition to the foregoing, the Fund may advertise its total return for
each Class over different periods of time by means of aggregate, average,
year-by-year or other types of total return figures. Such calculation may or may
not reflect the imposition of the maximum front end sales charge for Class A or
the deduction of the CDSC for each of Class B and Class C which, if reflected,
would reduce the performance quoted. For example, the average annual total
return of the Fund in the manner described in the preceding paragraph, but
without the deduction for any applicable sales charge. Based on the foregoing
calculation, the Fund's total return for Class A shares for the year ended
August 31, 1996 was 11.07%, the total return for the five years ended August 31,
1996 was 15.77% and the total return for the ten years ended August 31, 1996 was
6.53%. Because the Class D shares are not subject to any sales charge, the Fund
would only advertise average annual total returns as calculated in the previous
paragraph.
    
 
   
    In addition, the Fund may compute its aggregate total return for each Class
for specified periods by determining the aggregate percentage rate which will
result in the ending value of a hypothetical $1,000 investment made at the
beginning of the period. For the purpose of this calculation, it is assumed that
all dividends and distributions are reinvested. The formula for computing
aggregate total return involves a percentage obtained by dividing the ending
value (without reduction for any sales charge) by the initial $1,000 investment
and subtracting 1 from the result. Based on the foregoing calculation, the
Fund's restated total return for both Class A and Class D shares for the year
ended August 31, 1996 was 11.07%; the restated total return for the five years
ended August 31, 1996 was 107.95%; and the restated total return for the ten
years ended August 31, 1996 was 88.16%.
    
 
   
    The Fund may advertise the growth of hypothetical investments of $10,000,
$50,000 and $100,000 in each Class of shares of the Fund by adding 1 to the
Fund's aggregate total return to date (expressed as a decimal and without taking
into account the effect of any applicable CDSC) and multiplying by $9,575,
$48,250 and $97,250 in the case of Class A (investments of $10,000, $50,000 and
$100,000 adjusted for the initial sales charge) or by $10,000, $50,000 and
$100,000 in the case of each of Class B,
    
 
                                       33
<PAGE>
   
Class C and Class D, as the case may be. Investments of $10,000, $50,000 and
$100,000 in the Fund at inception would have grown to $45,959, $231,595 and
$466,790, respectively, in the case of Class A, and $47,999, $239,995 and
$479,990, respectively, in the case of Class D, at August 31, 1996.
    
 
   
    For the 30-day period ended August 31, 1996, the Fund's actual yield,
calculated pursuant to the formula described above, was 11.73%. The average
annual total returns of the Fund, calculated pursuant to the formula described
above, for the year ended August 31, 1996, for the five years ended August 31,
1996, and for the ten years ended August 31, 1996, were 4.96%, 14.47% and 5.92%,
respectively. The average annual total returns of the Fund calculated without
the deduction for any applicable sales charge for the year ended August 31,
1996, for the five years ended August 31, 1996, and for the ten years ended
August 31, 1996, were 11.07%, 15.77% and 6.53%, respectively. The Fund's
aggregate total return, calculated pursuant to the formula described above, for
the year ended August 31, 1996 was 11.07%, the total return for the five years
ended August 31, 1996 was 107.95% and the total return for the ten years ended
August 31, 1996 was 88.16%. Investments of $10,000, $50,000 and $100,000,
adjusted for the sales charges in effect at such time (5.5%, 4.25% or 3.25%,
respectively), in the Fund at inception would have grown to $45,359, $229,795
and $464,390, respectively, at August 31, 1996.

    The Fund is authorized to issue 2 billion shares of common stock of $0.01

are fully paid, non-assessable, fully transferable and redeemable at the option
of the holder. All shares are equal as to earnings, assets and voting
privileges. There are no conversion, preemptive or other subscription rights. In
the event of liquidation, each share of common stock of the Fund is entitled to
its portion of all of the Fund's assets after all debts and expenses have been
paid. Except for agreements entered into by the Fund in its ordinary course of
business within the limitations of the Fund's fundamental investment policies
(which may be modified only by shareholder vote), the Fund will not issue any
securities other than common stock.

directors can elect 100% of the directors if they choose to do so, and in such
event, the holders of the remaining less than 50% of the shares voting for the

1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter High Yield Securities Inc. (the "Fund") is registered under the
Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company. The Fund's primary investment objective is to
earn a high level of current income and, as a secondary objective, capital
appreciation, but only when consistent with its primary objective. The Fund was
incorporated in Maryland on June 14, 1979.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual results could differ from
those estimates. The following is a summary of significant accounting policies:
 
A. VALUATION OF INVESTMENTS --  (1) an equity security listed or traded on the
New York or American Stock Exchange is valued at its latest sale price on that
exchange prior to the time when assets are valued; if there were no sales that
day, the security is valued at the latest bid price; (2) all other portfolio
securities for which over-the-counter market quotations are readily available
are valued at the latest available bid price prior to the time of valuation; (3)
when market quotations are not readily available, portfolio securities are
valued at their fair value as determined in good faith under procedures
established by and under the general supervision of the Directors (valuation of
debt securities for which market quotations are not readily available may be
based upon current market prices of securities which are comparable in coupon,
rating and maturity or an appropriate matrix utilizing similar factors); (4)
certain portfolio securities may be valued by an outside pricing service
approved by the Directors. The pricing service utilizes a matrix system
incorporating security quality, maturity and coupon as the evaluation model
parameters, and/or research and evaluations by its staff, including review of
broker-dealer market price quotations, if available, in determining what it
believes is the fair valuation of the portfolio securities valued by such
pricing service; and (5) short-term debt securities having a maturity date of
more than sixty days at time of purchase are valued on a mark-to-market basis
until sixty days prior to maturity and thereafter at amortized cost based on
their value on the 61st day. Short-term debt securities having a maturity date
of sixty days or less at the time of purchase are valued at amortized cost.
 
B. ACCOUNTING FOR INVESTMENTS --  Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Dividend income and other distributions are recorded on the ex-dividend date.
Discounts are accreted over the life of the respective securities. Interest
income is accrued daily except where collection is not expected.

DEAN WITTER HIGH YIELD SECURITIES INC.
NOTES TO FINANCIAL STATEMENTS AUGUST 31, 1996, CONTINUED
 
C. FEDERAL INCOME TAX STATUS --  It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable income to its shareholders.
Accordingly, no federal income tax provision is required.
 
D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS --  The Fund records dividends
and distributions to its shareholders on the record date. The amount of
dividends and distributions from net investment income and net realized capital
gains are determined in accordance with federal income tax regulations which may
differ from generally accepted accounting principles. These "book/tax"
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the capital accounts based on their federal tax-basis treatment;
temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for financial reporting purposes but not for tax purposes are reported as
dividends in excess of net investment income or distributions in excess of net
realized capital gains. To the extent they exceed net investment income and net
realized capital gains for tax purposes, they are reported as distributions of
paid-in-capital.
 
2. INVESTMENT MANAGEMENT AGREEMENT
 
Pursuant to an Investment Management Agreement with Dean Witter InterCapital
Inc. (the "Investment Manager"), the Fund pays the Investment Manager a

REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND BOARD OF DIRECTORS
OF DEAN WITTER HIGH YIELD SECURITIES INC.
 
In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Dean Witter High Yield Securities
Inc. (the "Fund") at August 31, 1996, the results of its operations for the year
then ended, the changes in its net assets for each of the two years in the
period then ended and the financial highlights for each of the ten years in the
period then ended, in conformity with generally accepted accounting principles.
These financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities at August
31, 1996 by correspondence with the custodian and brokers, provide a reasonable
basis for the opinion expressed above.

NOTES TO FINANCIAL STATEMENTS FEBRUARY 28, 1997 (UNAUDITED)
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter High Yield Securities Inc. (the "Fund") is registered under the
Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company. The Fund's primary investment objective is to
earn a high level of current income and, as a secondary objective, capital
appreciation, but only when consistent with its primary objective. The Fund was
incorporated in Maryland on June 14, 1979 and commenced operations on September
26, 1979.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual results could differ from
those estimates.
 
The following is a summary of significant accounting policies:
 
A. VALUATION OF INVESTMENTS -- (1) an equity security listed or traded on the
New York, American or other domestic or foreign stock exchange is valued at its
latest sale price on that exchange prior to the time when assets are valued; if
there were no sales that day, the security is valued at the latest bid price (in
cases where securities are traded on more than one exchange, the securities are
valued on the exchange designated as the primary market pursuant to procedures
adopted by the Directors); (2) all other portfolio securities for which
over-the-counter market quotations are readily available are valued at the
latest available bid price prior to the time of valuation; (3) when market
quotations are not readily available, including circumstances under which it is
determined by Dean Witter InterCapital Inc. (the "Investment Manager") that sale
or bid prices are not reflective of a security's market value, portfolio
securities are valued at their fair value as determined in good faith under
procedures established by and under the general supervision of the Directors
(valuation of debt securities for which market quotations are not readily
available may be based upon current market prices of securities which are
comparable in coupon, rating and maturity or an appropriate matrix utilizing
similar factors); (4) certain portfolio securities may be valued by an outside
pricing service approved by the Directors. The pricing service may utilize a
matrix system incorporating security quality, maturity and coupon as the
evaluation model parameters, and/or research and evaluations by its staff,
including review of broker-dealer market price quotations, if available, in
determining what it believes is the fair valuation of the portfolio securities
valued by such pricing service; and (5) short-term debt securities having a
maturity date of more than sixty days at time of purchase are valued on a
mark-to-market basis until sixty days prior to maturity and thereafter at
amortized cost based on their value on the 61st day. Short-term debt securities
having a maturity date of sixty days or less at the time of purchase are valued
at amortized cost.

B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Dividend income and other distributions are recorded on the ex-dividend date.
Discounts are accreted over the life of the respective securities. Interest
income is accrued daily except where collection is not expected.
 
C. FEDERAL INCOME TAX STATUS -- It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable income to its shareholders.
Accordingly, no federal income tax provision is required.
 
D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends and
distributions to its shareholders on the record date. The amount of dividends
and distributions from net investment income and net realized capital gains are
determined in accordance with federal income tax regulations which may differ
from generally accepted accounting principles. These "book/tax" differences are
either considered temporary or permanent in nature. To the extent these
differences are permanent in nature, such amounts are reclassified within the
capital accounts based on their federal tax-basis treatment; temporary
differences do not require reclassification. Dividends and distributions which
exceed net investment income and net realized capital gains for financial
reporting purposes but not for tax purposes are reported as dividends in excess
of net investment income or distributions in excess of net realized capital
gains. To the extent they exceed net investment income and net realized capital
gains for tax purposes, they are reported as distributions of paid-in-capital.
 
2. INVESTMENT MANAGEMENT AGREEMENT
 
Pursuant to an Investment Management Agreement, the Fund pays the Investment
Manager a management fee, calculated daily and payable monthly, by applying the
following annual rates to the net assets of the Fund determined as of the close
of each business day: 0.50% to the portion of daily net assets not exceeding
$500 million; 0.425% to the portion of daily net assets exceeding $500 million
but not exceeding $750 million; 0.375% to the portion of daily net assets
exceeding $750 million but not exceeding $1 billion; 0.35% to the portion of
daily net assets exceeding $1 billion but not exceeding $2 billion; 0.325% to
the portion of daily net assets exceeding $2 billion but not exceeding $3
billion; and 0.30% to the portion of daily net assets exceeding $3 billion.
 
Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes, at its own expense, office space, facilities, equipment,
clerical, bookkeeping and certain legal services and pays the salaries of
 
                                       60

all personnel, including officers of the Fund who are employees of the
Investment Manager. The Investment Manager also bears the cost of telephone
services, heat, light, power and other utilities provided to the Fund.
 
3. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES
 
The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the six months ended February 28, 1997, aggregated
$237,747,854 and $220,427,940, respectively.
 
Dean Witter Trust Company, an affiliate of the Investment Manager, is the Fund's
transfer agent. At February 28, 1997, the Fund had transfer agent fees and
expenses payable of approximately $56,000.
 
The Fund has an unfunded noncontributory defined benefit pension plan covering
all independent Directors of the Fund who will have served as independent
Directors for at least five years at the time of retirement. Benefits under this
plan are based on years of service and compensation during the last five years
of service. Aggregate pension costs for the six months ended February 28, 1997
included in Directors' fees and expenses in the Statement of Operations amounted
to $635. At February 28, 1997, the Fund had an accrued pension liability of
$48,911 which is included in accrued expenses in the Statement of Assets and
Liabilities.
 
Shares of the Fund are distributed by Dean Witter Distributors Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Distributor has
informed the Fund that for the six months ended February 28, 1997, it received
approximately $963,000 in commissions from the sale of shares of the Fund's
capital stock. Such commissions are deducted from the proceeds of the capital
stock shares and are not an expense of the Fund.

Item 27. INDEMNIFICATION.
          

    Reference is made to Section 3.15 of the Registrant's By-Laws and Section
2-418 of the Maryland General Corporation Law.

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

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

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

                    DEAN WITTER HIGH YIELD SECURITIES INC.
                            ARTICLES OF AMENDMENT

   Dean Witter High Yield Securities Inc., a Maryland Corporation (the
"Corporation") having its principal office in Baltimore, Maryland, hereby
certifies to the State Department of Assessments and Taxation of Maryland
that:

   FIRST: The Articles of Incorporation of the Corporation (the "Articles")
are hereby amended as follows:

     Article V, Section (2) is renumbered as Section (3) and a new Section (2)
    is hereby inserted to read as follows:

        (2) The Corporation is authorized to issue its shares in two or more
       series or two or more classes, and subject to the requirements of the
       Investment Company Act of 1940, as amended, particularly Section 18(f)
       thereof and Rule 18f-2 thereunder, the different series or classes
       shall be established and designated, and the variations in the
       relative preferences, conversion and other rights, voting powers,
       restrictions, limitations as to dividends, qualifications and terms
       and conditions of redemption as between the different series or
       classes shall be fixed and determined by the Board of Directors;
       provided that the Board of Directors shall not classify or reclassify
       any of such shares into any class or series of stock which is prior to
       any class or series of stock then outstanding with respect to rights
       upon the liquidation, dissolution or winding up of the affairs of, or
       upon any distribution of the general assets of, the Corporation,
       except that there may be variations so fixed and determined between
       different series or classes as to investment objective, purchase
       price, right of redemption, special rights as to dividends and on
       liquidation with respect to assets belonging to a particular series or
       class, voting powers and conversion rights. All references to Common
       Stock in these Articles shall be deemed to be shares of any or all
       series and classes as the context may require.

        The following is a description of the preferences, conversion and
       other rights, voting powers, restrictions, limitations as to
       dividends, qualifications and terms and conditions of redemption of
       any additional class or series of Common Stock of the Corporation
       (unless provided otherwise by the Board of Directors with respect to
       any such additional class or series at the time of establishing and
       designating such additional class or series):

        (a) The number of authorized Common Stock and the number of Common
       Stock of each series or of each class that may be issued shall be in
       such number as may be determined by the Board of Directors and
       reflected in Articles Supplementary filed with the Maryland State
       Department of Assessments and Taxation. The Directors may classify or
       reclassify any unissued Common Stock or any Common Stock previously
       issued and reacquired of any series or class into one or more series
       or one or more classes that may be established and designated from
       time to time. The Directors may reissue for such consideration and on
       such terms as they may determine, or cancel, any Common Stock of any
       series or any class reacquired by the Corporation at their discretion
       from time to time.

        (b) All consideration received by the Corporation for the issue or
       sale of Common Stock of a particular series or class, together with
       all assets in which such consideration is invested or reinvested, all
       income, earnings, profits and proceeds thereof, including any proceeds
       derived from the sale, exchange or liquidation of such assets, and any
       funds or payments derived from any reinvestment of such proceeds in
       whatever form the same may be, shall irrevocably belong to that series
       or class for all purposes, subject only to the rights of creditors,
       and shall be so recorded upon the books of account of the Corporation.
       In the event that there are any assets, income, earnings, profits and
       proceeds thereof funds, or payments which are not readily identifiable
       as belonging to any particular series or class, the Directors shall
       allocate them among any one or more of the series or classes
       established and designated from time to time in such manner and on
       such basis as they, in their sole discretion, deem fair and equitable.
       Each such allocation by the Corporation shall be conclusive and
       binding upon the stockholders of all series


<PAGE>
       or classes for all purposes. The Directors shall have full discretion,
       to the extent not inconsistent with the Investment Company Act of
       1940, as amended, and the Maryland General Corporation Law, to
       determine which items shall be treated as income and which items shall
       be treated as capital; and each such determination and allocation
       shall be conclusive and binding upon the stockholders.

        (c) The assets belonging to each particular series or class shall be
       charged with the liabilities of the Corporation in respect of that
       series or class and all expenses, costs, charges and reserves
       attributable to that series, and any general liabilities, expenses,
       costs, charges or reserves of the Corporation which are not readily
       identifiable as belonging to any particular series or class shall be
       allocated and charged by the Directors to and among any one or more of
       the series or classes established and designated from time to time in
       such manner and on such basis as the Directors in their sole
       discretion deem fair and equitable. Each allocation of liabilities,
       expenses, costs, charges and reserves by the Directors shall be
       conclusive and binding upon the stockholders of all series or classes
       for all purposes.

        (d) Dividends and distributions on Common Stock of a particular
       series or class may be paid with such frequency as the Directors may
       determine, which may be daily or otherwise, pursuant to a standing
       resolution or resolutions adopted only once or with such frequency as
       the Board of Directors may determine, to the holders of Common Stock
       of that series or class, from such of the income and capital gains,
       accrued or realized, from the assets belonging to that series or
       class, as the Directors may determine, after providing for actual and
       accrued liabilities belonging to that series or class. All dividends
       and distributions on Common Stock of a particular series or class
       shall be distributed pro rata to the holders of that series or class
       in proportion to the number of Common Stock of that series or class
       held by such holders at the date and time of record established for
       the payment of such dividends or distributions except that in
       connection with any dividend or distribution program or procedure, the
       Board of Directors may determine that no dividend or distribution
       shall be payable on shares as to which the stockholder's purchase
       order and/or payment in proper form have not been received by the time
       or times established by the Board of Directors under such program or
       procedure.

        The Corporation intends to have each separate series qualify as a
       "regulated investment company" under the Internal Revenue Code of
       1986, or any successor comparable statute thereto, and regulations
       promulgated thereunder. Inasmuch as the computation of net income and
       gains for Federal income tax purposes may vary from the computation
       thereof on the books of the Corporation, the Board of Directors shall
       have the power, in its sole discretion, to distribute in any fiscal
       year as dividends, including dividends designated in whole or in part
       as capital gains distributions, amounts sufficient, in the opinion of
       the Board of Directors, to enable the respective series to qualify as
       regulated investment companies and to avoid liability of such series
       for Federal income tax in respect of that year. However, nothing in
       the foregoing shall limit the authority of the Board of Directors to
       make distributions greater than or less than the amount necessary to
       qualify the series as regulated investment companies and to avoid
       liability of such series for such tax.

        Dividends and distributions may be made in cash, property or
       additional shares of the same or another class or series, or a
       combination thereof, as determined by the Board of Directors or
       pursuant to any program that the Board of Directors may have in effect
       at the time for the election by each stockholder of the mode of the
       making of such dividend or distribution to that stockholder. Any such
       dividend or distribution paid in shares will be paid at the net asset
       value thereof as defined in section (3) below.

        (e) In the event of the liquidation or dissolution of the Corporation
       or of a particular class or series, the stockholders of each class or
       series that has been established and designated and is being
       liquidated shall be entitled to receive, as a class or series, when
       and as declared by the Board of Directors, the excess of the assets
       belonging to the class or series over the liabilities belonging to
       that class or series. The holders of shares of any particular class or
       series shall not

                                  2
<PAGE>
       be entitled thereby to any distribution upon liquidation of any other
       class or series. The assets so distributable to the stockholders of
       any particular class or series shall be distributed among such
       stockholders in proportion to the number of shares of that class or
       series held by them and recorded on the books of the Corporation. The
       liquidation of any particular class or series in which there are
       shares then outstanding may be authorized by vote of a majority of the
       outstanding securities of that class or series, as defined in the
       Investment Company Act of 1940, as amended, and without the vote of
       the holders of any other class or series. The liquidation or
       dissolution of a particular class or series may be accomplished, in
       whole or in part, by the transfer of assets of such class or series to
       another class of series or by the exchange of shares of such class or
       series for the shares of another class or series.

        (f) On each matter submitted to a vote of the stockholders, each
       holder of a share shall be entitled to one vote for each share
       standing in his name on the books of the Corporation, irrespective of
       the class or series thereof, and all shares of all classes or series
       shall vote as a single class or series ("Single Class voting");
       provided, however, that (i) as to any matter with respect to which a
       separate vote of any class or series is required by the Investment
       Company Act of 1940, as amended, or by the Maryland General
       Corporation Law, such requirement as to a separate vote by that class
       or series shall apply in lieu of Single Class voting as described
       above; (ii) in the event that the separate vote requirements referred
       to in (i) above apply with respect to one or more classes or series,
       then, subject to (iii) below, the shares of all other classes or
       series shall vote as a single class or series; and (iii) as to any
       matter which does not affect the interest of a particular class or
       series, only the holders of shares of the one or more affected classes
       shall be entitled to vote.

        (g) The establishment and designation of any series or class of
       Common Stock shall be effective upon the adoption by a majority of the
       then Directors of a resolution setting forth such establishment and
       designation and the relative rights and preferences of such series or
       class, or as otherwise provided in such instrument, and the filing
       with the proper authority of the State of Maryland of Articles
       Supplementary setting forth such establishment and designation and
       relative rights and preferences.

   SECOND: The Amendment was recommended by the Corporation's Board of
Directors and approved by the holders of a majority of the outstanding common
stock entitled to vote thereon.

                                ARTICLES SUPPLEMENTARY


          Dean Witter High Yield Securities Inc., a Maryland corporation, having
its principal office in Baltimore City, Maryland 21202 (hereinafter called the
"Corporation"), hereby certifies to the State Department of Assessments and
Taxation of Maryland that:


          FIRST:  In accordance with Section 2-105(c) of the Maryland General
Corporation Law, the Board of Directors ("Board") has increased the authorized
capital stock of the Corporation to 2,000,000,000 shares of Common Stock, par
value $.01 per share.


          SECOND:  Pursuant to authority expressly vested in the Board of
Directors of the Corporation by Article V, Section 2(g) of the Articles of
Incorporation (the "Articles"), the Board has duly established three additional
classes of the Common Stock, par value $.01 per share, of the Corporation to be
classified as Class A, Class B and Class C (the "Additional Classes") of which
500,000,000, 500,000,000 and 500,000,000 shares, respectively, have been
authorized and the Board has provided for the issuance of such Additional
Classes.


          THIRD:  The terms applicable to the Additional Classes of the Common
Shares as set by the Board of Directors, including preferences, conversion or
other rights, voting powers, restrictions, limitations as to dividends,
qualifications, or terms or conditions of redemption, are the same as the terms
of the existing class of Common Stock ("Existing Class") which are set forth in
the Articles, except that:

          (1)  The Class A, Class C, and Class D shares of capital stock 
     shall represent the same interest in the Corporation and have, except as 
     provided to the contrary in these Articles Supplementary or in any 
     subsequently filed charter document, identical voting, dividend, 
     liquidation, and other rights, terms and conditions with any other 
     shares of capital stock; provided however, that notwithstanding anything 
     in the Charter of the Corporation to the contrary, shares of the various 
     Classes of capital stock shall be subject to such different combination 
     of sales charges, ongoing fees and other features, as may be established 
     from time to time by the Board of Directors in accordance with the 
     Investment Company Act of 1940, as amended, and any rules or regulations 
     promulgated thereunder (the "1940 Act") and applicable rules and 
     regulations of the National Association of Securities Dealers, Inc. (the 
     "NASD") and as shall be set forth in the applicable prospectus for the 
     shares or the Corporation's then-current Multiple-Class Plan adopted 
     pursuant to Rule 18f-3 under the 1940 Act or any successor provision 
     thereto; and provided further that expenses paid pursuant to a plan of 
     distribution under Rule 12b-1 of the 1940 Act (and certain other 
     expenses that are related solely to a particular Class of capital stock, 
     as the Board of Directors may determine), shall be borne solely by such

<PAGE>

     Class and shall be appropriately reflected (in the manner determined by the
     Board of Directors) in the net asset value, dividends, distribution and
     liquidation rights of the shares of the Class in question;

          (2)  On each matter submitted to a vote of the stockholders, 
     including without limitation, the provisions of any distribution plan 
     adopted by the Board of Directors pursuant to Rule 12b-1 under the 1940 
     Act, each holder of a Share shall be entitled to one vote for each such 
     Share standing in his name on the books of the Corporation irrespective 
     of the Class thereof, and all Shares of all Classes shall vote as a 
     single class ("Single Class Voting"); provided, however, that (A) as to 
     any matter with respect to which a separate vote of any Class as 
     required or permitted by the 1940 Act or would be required under the 
     Maryland General Corporation Law, such requirements as to a separate 
     vote by that Class, as applicable, shall apply in lieu of Single Class 
     Voting as described above; (B) in the event that the separate vote 
     requirements referred to in (A) above apply with respect to one or more 
     Classes, then the Shares of all other Classes shall vote together as a 
     single Class, unless such Shares are not required to be voted under 
     clause (C) of this paragraph or otherwise under law; and (C) as to any 
     matter which does not materially affect the interest of a particular 
     Class, only the holders of Shares of the one or more affected Classes 
     shall be entitled to vote; and

          (3)  Shares of the Class B Common Stock shall be automatically 
     converted into shares of the Class A at such time or times, not to 
     exceed 20 years from the date of initial issuance, as shall be set forth 
     in the applicable prospectus or Multiple-Class Plan, as amended from 
     time to time, and in the event no such provision is set forth in the 
     prospectus or Multiple Class Plan, shall not be so convertible.

          FOURTH:  The Corporation is registered as an open-end investment
company under the 1940 Act.


          FIFTH:  (a)  As of immediately before the increase of authorized
shares, the total number of shares of stock of all classes which the Corporation
had authority to issue was 400,000,000 shares of Common Stock, par value $.01
per share.  As increased, the total number of shares of stock of all classes
which the Corporation has authority to issue is 2,000,000,000 shares of Common
Stock, par value $.01 per share.

          (b)  As of immediately before the increase, 400,000,000 shares of the
Existing Class with an aggregate par value of $4,000,000 were authorized.  As
increased, 500,000,000 shares of each of the Additional Classes and the Existing
Class  (each a "Class"), with an aggregate par value of $5,000,000 per Class,
are authorized.

          (c)  The aggregate par value of all shares having a par value was
$4,000,000 before the increase and $20,000,000 as increased.

such place, within or without the State of Maryland, as may be designated
from time to time by the Board of Directors.

   SECTION 2.2. ANNUAL MEETINGS. An annual meeting of stockholders, when
required, at which the stockholders shall elect a Board of Directors and
transact such other business as may properly come before the meeting, shall
be held in December of each year, the precise date in December to be fixed by
the Board of Directors. Notwithstanding anything to the contrary contained
herein, the Corporation shall not be required to hold an annual meeting in
any year in which none of the following is required to be acted upon by
stockholders under the Investment Company Act of 1940, as amended:

     (1) election of directors;

     (2) approval of an investment advisory or management agreement;

     (3) ratification of the selection of independent accountants; and

     (4) approval of a distribution plan or agreement;

provided, however, that a special meeting of stockholders shall promptly be
called when requested in writing by the recordholders of not less than 10% of
the Corporation's shares.

   SECTION 2.3. SPECIAL MEETINGS. Special meetings of stockholders of the
Corporation shall be held whenever called by the Board of Directors or the
President of the Corporation. Special meetings of stockholders shall also be
called by the Secretary upon the written request of the holders of shares
entitled to vote not less than twenty-five percent (25%) of all the votes
entitled to be cast at such meeting. Such request shall state the purpose or
purposes of such meeting and the matters proposed to be acted on thereat. The
Secretary shall inform such stockholders of the reasonable estimated cost of
preparing and mailing such notice of the meeting, and upon payment to the
Corporation of such costs, the Secretary shall give notice stating the
purpose or purposes of the meeting to all entitled to a vote at such meeting.
Unless requested by stockholders entitled to cast a majority of all the votes
entitled to be cast at the meeting, a special meeting need not be called to
consider any matter which is substantially the same as a matter voted upon at
any special meeting of stockholders held during the preceding twelve months.

stockholders' meeting stating the place, date and time, and in the case of a
special meeting the purpose or purposes thereof, shall be given by the

                                1
<PAGE>
stockholder entitled to vote at such meeting, either by mail or by presenting
it to him personally, or by leaving it at his residence or usual place of

in the United States mail, postage prepaid, directed to the stockholder at
his address as it appears on the records of the Corporation.

   SECTION 2.5. QUORUM AND ADJOURNMENT OF MEETINGS. Except as otherwise
provided by law, by the Charter of the Corporation, or by these By-Laws, at
all meetings of stockholders the holders of a majority of the shares issued
and outstanding and entitled to vote thereat, present in person or
represented by proxy, shall be requisite and shall constitute a quorum for
the transaction of business. In the absence of a quorum, the stockholders
present or represented by proxy and entitled to vote thereat shall have power
to adjourn the meeting from time to time without notice other than
announcement at the meeting, until a quorum shall be present. At any
adjourned meeting at which a quorum shall be present, any business may be
transacted if the meeting had been held as originally called.

   SECTION 2.6. VOTING RIGHTS, PROXIES. At each meeting of the stockholders
at which a quorum is present, each holder of stock entitled to vote thereat
shall be entitled to one vote in person or by proxy, executed in writing by
the stockholder or his duly authorized attorney-in-fact, for each share of
stock of the Corporation entitled to vote so registered in his name on the
books of the Corporation on the date fixed as the record date for the
determination of stockholders entitled to vote at such meeting. No proxy
shall be valid after eleven months from its date, unless otherwise provided
in the proxy. At all meetings of stockholders, unless the voting is conducted
by inspectors, all questions relating to the qualification of voters and the
validity of proxies and the acceptance or rejection of votes shall be decided
by the chairman of the meeting.

   SECTION 2.7. VOTE REQUIRED. Except as otherwise provided by law, by the
Charter of the Corporation, or by these By-Laws, at each meeting of
stockholders at which a quorum is present, any election shall be decided by a
plurality, and all other questions shall be decided by a majority of the
votes cast by the stockholders present in person or represented by proxy and
entitled to vote in such election or with respect to any such matter.

   SECTION 2.8. ACTION BY STOCKHOLDERS WITHOUT MEETING. Except as otherwise
provided by law, the provisions of these By-Laws relating to notices and
meetings to the contrary notwithstanding, any action required or permitted to
be taken at any meeting of stockholders may be taken without a meeting if a
consent in writing setting forth the action shall be signed by all the
stockholders entitled to vote upon the action and such consent shall be filed
with the records of the Corporation.

   SECTION 2.9. PRESENCE AT MEETINGS. Presence at meetings of stockholders
requires physical attendance by the stockholder or his or her proxy at the
meeting site and does not encompass attendance by telephonic or other
electronic means.

                                 ARTICLE III

                                  DIRECTORS

   SECTION 3.1. NUMBER AND TERM. The Board of Directors shall consist of not
less than three (3) and not more than fifteen (15) directors, the number of
directors to be fixed from time to time within the above-specified limits by
the affirmative vote of a majority of the whole Board of Directors. At the
first annual meeting of stockholders and at each meeting thereafter, the
stockholders shall elect directors to hold office until their successors are
elected and qualify. Directors need not be stockholders of the Corporation.

   SECTION 3.2. POWERS. The business of the Corporation shall be managed by
the Board of Directors which may exercise all powers of the Corporation and
do all lawful acts and things which are not by law or by the Charter of the
Corporation, or by these By-Laws, directed or required to be exercised or
done exclusively by the stockholders.

   SECTION 3.3. ORGANIZATIONAL MEETINGS. The first meeting of each newly
elected Board of Directors for the purposes of organization and the election
of officers and otherwise shall be held at such time and place as shall be
specified in a notice given as hereinafter provided for special meetings of
the Board of Directors, or as shall be specified in a written waiver signed
by all directors.

                                2
<PAGE>
   SECTION 3.4. REGULAR MEETINGS. Regular meetings of the Board of Directors
may be held at such time and place as shall be determined from time to time
by the Board of Directors without further notice.

   SECTION 3.5. SPECIAL MEETINGS. Special meetings of the Board of Directors
may be called at any time by the President and shall be called by such
President or the Secretary upon the written request of any two (2) directors.

   SECTION 3.6. NOTICE OF SPECIAL MEETINGS. Written notice of special
meetings of the Board of Directors, stating the place, date and time thereof,
shall be given not less than two (2) days before such meeting to each
director, personally, by telegram, by mail, or by leaving such notice at his
place of residence or usual place of business. If mailed, such notice shall
be deemed to be given when deposited in the United States mail, postage
prepaid, directed to the director at his address as it appears on the records
of the Corporation.

   SECTION 3.7. TELEPHONE MEETINGS. Any member or members of the Board of
Directors or of any committee designated by the Board, may participate in a
meeting of the Board, or any such committee, as the case may be, by means of
a conference telephone or similar communications equipment if all persons
participating in the meeting can hear each other at the same time.
Participation in a meeting by these means constitutes presence in person at
the meeting.

   SECTION 3.8. QUORUM, VOTING AND ADJOURNMENT OF MEETINGS. At all meetings
of the Board of Directors, a majority of the whole Board shall be requisite
to and shall constitute a quorum for the transaction of business. If a quorum
is present, the affirmative vote of a majority of the directors present shall
be the act of the Board of Directors, unless the concurrence of a greater
proportion is expressly required for such action by law, the Charter of the
Corporation or these By-Laws. If at any meeting of the Board there be less
than a quorum present, the directors present thereat may adjourn the meeting
from time to time, without notice other than announcement at the meeting
until a quorum shall have been obtained.

   SECTION 3.9. REMOVAL. Any one or more of the directors may be removed,
either with or without cause, at any time, by the affirmative vote of the
stockholders holding a majority of the outstanding shares entitled to vote
for the election of directors. (For purposes of determining the circumstances
and procedures under which such removal of directors may take place, the
provisions of Section 16(c) of the Investment Company Act of 1940 shall be
applicable to the same extent as if the Corporation were subject to the
provisions of that Section.) The successor or successors of any director or
directors so removed may be elected by the stockholders entitled to vote
thereon at the same meeting to fill any resulting vacancies for the unexpired
term of removed directors. Except as provided by law, pending such an
election (or in the absence of such an election), the successor or successors
of any director or directors so removed may be chosen by the Board of
Directors.

   SECTION 3.10. VACANCIES. Except as otherwise provided by law, any vacancy
occurring in the Board of Directors and newly created directorships resulting
from an increase in the authorized number of directors may be filled by the
vote of a majority of the directors then in office or, if only one director
shall then be in office, by such director. A director elected by the Board of
Directors to fill a vacancy shall be elected to hold office until the next
annual meeting of stockholders or until his successor is elected and
qualifies.

   SECTION 3.11. ACTION BY DIRECTORS WITHOUT MEETING. The provisions of these
By-Laws covering notices and meetings to the contrary notwithstanding, and
except as required by law, any action required or permitted to be taken at
any meeting of the Board of Directors may be taken without a meeting if a
consent in writing setting forth the action shall be signed by all of the
directors entitled to vote upon the action and such written consent is filed
with the minutes of proceedings of the Board of Directors.

   SECTION 3.12. EXPENSES AND FEES. Each director may be allowed expenses, if
any, for attendance at each regular or special meeting of the Board of
Directors and each director who is not an officer or employee of the
Corporation or of its investment manager or underwriter or of any corporate
affiliate of any of said persons shall receive for services rendered as a
director of the Corporation such compensation as may be fixed by the Board of
Directors. Nothing herein contained shall be construed to preclude any
director from serving the Corporation in any other capacity and receiving
compensation therefor.

                                3
<PAGE>
   SECTION 3.13. EXECUTION OF INSTRUMENTS AND DOCUMENTS AND SIGNING OF CHECKS
AND OTHER OBLIGATIONS AND TRANSFERS. All instruments, documents and other
papers shall be executed in the name and on behalf of the Corporation and all
checks, notes, drafts and other obligations for the payment of money by the
Corporation shall be signed, and all transfer of securities standing in the
name of the Corporation shall be executed, by the President, any Vice
President or the Treasurer or by any one or more officers or agents of the
Corporation as shall be designated for that purpose by vote of the Board of
Directors; notwithstanding the above, nothing in this Section 3.13 shall be
deemed to preclude the electronic authorization, by designated persons, of
the Corporation's Custodian to transfer assets of the Corporation.

   SECTION 3.14. CONTRACTS. Except as otherwise provided by law or by the
Charter of the Corporation, no contract or transaction between the
Corporation and any partnership or corporation, and no act of the
Corporation, shall in any way be affected or invalidated by the fact that any
officer or director of the Corporation is pecuniarily or otherwise interested
therein or is a member, officer or director of such interest shall be known
to the Board of Directors of the Corporation. Specifically, but without
limitation of the foregoing, the Corporation may enter into one or more
contracts appointing Dean Witter InterCapital Inc. investment manager of the
Corporation, and may otherwise do business with Dean Witter InterCapital
Inc., notwithstanding the fact that one or more of the directors of the
Corporation and some or all of its officers are, have been or may become
directors, officers, members, employees, or stockholders of Dean Witter
InterCapital Inc.; and in the absence of fraud, the Corporation and Dean
Witter InterCapital Inc. may deal freely with each other, and neither such
contract appointing Dean Witter InterCapital Inc. investment manager to the
Corporation nor any other contract or transaction between the Corporation and
Dean Witter InterCapital Inc. shall be invalidated or in any wise affected
thereby, nor shall any director or officer of the Corporation by reason
thereof be liable to the Corporation or to any stockholder or creditor of the
Corporation or to any other person for any loss incurred under or by reason
of any such contract or transaction. For purposes of this paragraph, any
reference to "Dean Witter InterCapital Inc." shall be deemed to include said
company and any parent, subsidiary or affiliate of said company and any
successor (by merger, consolidation or otherwise) to said company or any such
parent, subsidiary or affiliate.

   SECTION 3.15. INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES AND
AGENTS. (a) The Corporation shall indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending, or completed
action, suit, or proceeding, whether civil, criminal, administrative, or
investigative (other than an action by or in the right of the Corporation) by
reason of the fact that he is or was a director, officer, employee or agent
of the Corporation. The indemnification shall be against expenses, including
attorneys' fees, judgments, fines, and amounts paid in settlement, actually
and reasonably incurred by him in connection with the action, suit, or
proceeding, if he acted in good faith and in a manner he reasonably believed
to be in or not opposed to the best interests of the Corporation, and, with
respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful. Directors acting in their official capacity
must act in good faith and in a manner reasonably believed to be in the best
interest of the Corporation. The termination of any action, suit, or
proceeding by judgment, order, settlement, conviction, or upon a plea of nolo
contendere or its equivalent shall not, of itself, create a presumption that
the person did not act in good faith and in a manner which he reasonably
believed to be in or not opposed to the best interests of the Corporation,
and, with respect to any criminal action or proceeding, had reasonable cause
to believe that his conduct was unlawful. A director may not be indemnified
in respect of any proceeding charging improper personal benefit to the
director, whether or not involving action in the director's official
capacity, in which the director was adjudged to be liable on the basis that
personal benefit was improperly received.

   (b) The Corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action
or suit by or on behalf of the Corporation to obtain a judgment or decree in
its favor by reason of the fact that he is or was a director, officer,
employee, or agent of the Corporation. The indemnification shall be against
expenses, including attorney's fees actually and reasonably incurred by him
in connection with the defense or settlement of the action or suit if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best

                                4
<PAGE>
interests of the Corporation: except that no indemnification shall be made in
respect of any claim, issue, or matter as to which the person has been
adjudged to be liable for negligence or misconduct in the performance of his
duty to the Corporation, except to the extent that the court in which the
action or suit was brought, or a court of equity in the county in which the
Corporation has its principal office, determines upon application that,
despite the adjudication of liability, but in view of all circumstances of
the case, the person is fairly and reasonably entitled to indemnity for those
expenses which the court shall deem proper, provided such director or officer
is not adjudged to be liable by reason of his willful misfeasance, bad faith,
gross negligence or reckless disregard of the duties involved in the conduct
of his office.

   (c) To the extent that a director, officer, employee, or agent of the
Corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in subsection (a) or (b) or in defense
of any claim, issue or matter therein, he shall be indemnified against
expenses, including attorneys' fees, actually and reasonably incurred by him
in connection therewith.

   (d)(1) Unless a court orders otherwise, any indemnification under
subsection (a) or (b) of this section may be made by the Corporation only as
authorized in the specific case after a determination that indemnification of
the director, officer, employee, or agent is proper in the circumstances
because he has met the applicable standard of conduct set forth in subsection
(a) or (b).

      (2) The determination shall be made:

        (i) By the Board of Directors, by a majority vote of a quorum which
     consists of directors who were not parties to the action ("non-party
     directors"), suit or proceeding; or if a quorum of non-party directors
     is not obtainable by a majority vote of a committee of at least two
     non-party directors; or

       (ii) If the required quorum is not obtainable; or if a quorum of
     disinterested directors so directs, by independent legal counsel in a
     written opinion; or

      (iii) By the stockholders.

      (3) Authorization of indemnification and determination as to
reasonableness of expenses shall be made in the same manner as the
determination that indemnification is permissible. However, if the
determination that indemnification is permissible is made by independent
legal counsel, authorization of indemnification and determination as to
reasonableness of expenses shall be made by a committee of non-party
directors or by the non-party quorum of the Board, or if neither exists, by
the full Board.

      (4) Notwithstanding the provisions of paragraphs (1) and (2) of this
subsection (d), no person shall be entitled to indemnification for any
liability, whether or not there is an adjudication of liability, arising by
reason of willful misfeasance, bad faith, gross negligence, or reckless
disregard of duties as described in Sections 17(h) and (i) of the Investment
Company Act of 1940, as amended ("disabling conduct"). A person shall be
deemed not liable by reason of disabling conduct if, either:

       (i) a final decision on the merits is made by a court or other body
     before whom the proceeding was brought that the person to be indemnified
     ("indemnitee") was not liable by reason of disabling conduct; or

      (ii) in the absence of such a decision, a reasonable determination,
     based upon a review of the facts, that the indemnitee was not liable by
     reason of disabling conduct, is made by either--

          (A) a majority of a quorum of directors who are neither "interested
         persons" of the Corporation, as defined in Section 2(a)(19) of the
         Investment Company Act of 1940, as amended, nor parties to the
         action, suit or proceeding, or

          (B) an independent legal counsel in a written opinion.

   (e) Expenses, including attorneys' fees, incurred by a director, officer,
employee or agent of the Corporation in defending a civil or criminal action,
suit or proceeding may be paid by the Corporation in advance of the final
disposition thereof if:

                                5
<PAGE>
    (1) authorized in the specific case by the Board of Directors; and

    (2) the Corporation receives an undertaking by or on behalf of the
   director, officer, employee or agent of the Corporation to repay the
   advance if it is not ultimately determined that such person is entitled to
   be indemnified by the Corporation; and

    (3) either

          (i) such person provides a security for his undertaking, or

         (ii) the Corporation is insured against losses by reason of any
       lawful advances, or

        (iii) a determination, based on a review of readily available facts,
       that there is reason to believe that such person ultimately will be
       found entitled to indemnification, is made by either--

            (A) a majority of a quorum which consists of directors who are
           neither "interested persons" of the Corporation, as defined in
           Section 2(a)(19) of the Investment Company Act of 1940, as
           amended, nor parties to the action, suit or proceeding, or

            (B) an independent legal counsel in a written opinion.

   (f) The indemnification provided by this Section shall not be deemed
exclusive of any other rights to which a person may be entitled under any
by-law, agreement, vote of stockholders or disinterested directors or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding the office, and shall continue as to a person
who has ceased to be a director, officer, employee, or agent and inure to the
benefit of the heirs, executors and administrators of such person.

   (g) The Corporation may purchase and maintain insurance on behalf of any
person who is or was a director, officer, employee, or agent of the
Corporation, against any liability asserted against him and incurred by him
in any such capacity, or arising out of his status as such. However, in no
event will the Corporation pay for that portion of the premium, if any, for
insurance to indemnify any officer or director against liability for any act
for which the Corporation itself is not permitted to indemnify him.

   (h) Nothing contained in this Section shall be construed to protect any
director or officer of the Corporation against any liability to the
Corporation or to its security holders to which he would otherwise be subject
by reason of willful misfeasance, bad faith, gross negligence or reckless
disregard of the duties involved in the conduct of his office.

   (i) Any indemnification of, or advance of expenses to, a director in
accordance with this Section, if arising out of a proceeding by or in the
right of the Corporation, shall be reported in writing to the shareholders
with the notice of the next stockholders' meeting or prior to the meeting.

sold or otherwise disposed of by the Corporation. The number of persons
constituting any such advisory committee shall be determined from time to
time by the Board of Directors. The members of any such advisory committee
may receive compensation for their services and may be allowed such fees and
expenses for the attendance at meetings as the Board of Directors may from
time to time determine to be appropriate.

setting forth the action shall be signed by all members of the Committee
entitled to vote upon the action and such written consent is filed with the
records of the proceedings of the Committee.

of the capital stock of the Corporation shall be in such form and of such
design as the Board of Directors shall approve, subject to the right of the
Board of Directors to change such form and design at any time or from time to

   In case any officer or officers who shall have signed, or whose facsimile
signature or signatures shall appear on, any such certificate or certificates
shall cease to be such officer or officers of the Corporation, whether
because of death, resignation or otherwise, before such certificate or
certificates shall have been delivered by the Corporation, such certificate

fully paid.

   SECTION 6.3. TRANSFER OF STOCK. Transfers of shares of the capital stock

certificate, or his legal representative, to give to the Corporation and to
such Registrar, Transfer Agent and/or Transfer Clerk as may be authorized or
required to countersign such new certificate or certificates, a bond in such
sum and of such type as they may direct, and with such surety or sureties, as

any of them on account of or in connection with the alleged loss, theft or
destruction of any such certificate.

the

                                9
<PAGE>
owner of shares of stock, and shall not be bound to recognize any equitable
or other claim to or interest in such share or shares on the part of any
other person, whether or not it shall have express or other notice thereof,
except as otherwise provided by the laws of Maryland.

   SECTION 6.7. FRACTIONAL DENOMINATIONS. Subject to any applicable
provisions of law and the Charter of the Corporation, the Corporation may
issue shares of its capital stock in fractional denominations, provided that
the transactions in which and the terms and conditions upon which shares in

authority of the Board of Directors. Any shares so delivered or offered for

Directors in accordance with applicable laws and regulations; provided that
in no event shall such price be less than the applicable net asset value of
such shares. The Corporation shall pay redemption prices in cash.

                                 ARTICLE VIII

                         DIVIDENDS AND DISTRIBUTIONS

   Subject to any applicable provisions of law and the Charter of the
Corporation, dividends and distributions upon the Common Stock of the
Corporation may be declared at such intervals as the Board of Directors may
determine, in cash, in securities or other property, or in shares of stock of
the Corporation, from any sources permitted by law, all as the Board of
Directors shall from time to time determine.

   Inasmuch as the computation of net income and net profits from the sale of
securities or other properties for federal income tax purposes may vary from
the computation thereof on the books of the Corporation, the Board of
Directors shall have power, in its discretion, to distribute as income
dividends and as capital gain distributions, respectively, amounts sufficient
to enable the Corporation to avoid or reduce liability for federal income
taxes.

                                  ARTICLE IX

the provisions of the statute or under the provisions of the Charter of the
Corporation or these By-Laws, a waiver thereof in writing, signed by the

       5.  The Fund assumes and shall pay or cause to be paid all other 
expenses of the Fund, including without limitation: fees pursuant to any plan 
of distribution that the Fund may adopt; the charges and expenses of any 
registrar, any custodian or depository appointed by the Fund for the 
safekeeping of its cash, portfolio securities or commodities and other 
property, and any stock transfer or dividend agent or agents appointed by the 
Fund; brokers' commissions chargeable to the Fund in connection with 
portfolio transactions to which the Fund is a party; all taxes, including 
securities or commodities issuance and transfer taxes, and fees payable by 
the Fund to federal, state or other governmental agencies; the cost and 
expense of engraving or printing certificates representing shares of the 
Fund; all costs and expenses in connection with the registration and 
maintenance of registration of the Fund and its shares with the Securities 
and Exchange Commission and various states and other jurisdictions (including 
filing fees and legal fees and disbursements of counsel); the cost and 
expense of printing, including typesetting, and distributing prospectuses and 
statements of additional information of the Fund and supplements thereto to 
the Fund's shareholders; all expenses of shareholders' and Directors' 
meetings and of preparing, printing and mailing proxy statements and reports 
to shareholders; fees and travel expenses of Directors or members of any 
advisory board or committee who are not employees of the Investment Manager 
or any corporate affiliate of the Investment Manager; all expenses incident 
to the payment of any dividend, distribution, withdrawal or redemption, 
whether in shares or in cash; charges and expenses of any outside service 
used for pricing of the Fund's shares; charges and expenses of legal counsel, 
including counsel to the Directors of the Fund who are not interested persons 
(as defined in the Act) of the Fund or the Investment Manager, and of 
independent accountants, in connection with any matter relating to the Fund; 
membership dues of industry associations; interest payable on Fund 
borrowings; postage; insurance premiums on property or personnel (including 
officers and Directors) of the Fund which inure to its benefit; extraordinary 
expenses (including but not limited to legal claims and liabilities and 
litigation costs and any indemnification related thereto); and all other 
charges and costs of the Fund's operation unless otherwise explicitly 
provided herein.
 
       6.  For the services to be rendered, the facilities furnished, and the 
expenses assumed by the Investment Manager, the Fund shall pay to the 
Investment Manager monthly compensation determined by applying the following 
annual rates to the Fund's daily net assets: 0.50% of daily net assets up to 
$500 million; 0.425% of the next $250 million; 0.375% of the next $250 
million; 0.35% of the next $1 billion; 0.325% of the next $1 billion; and 
0.30% of daily net assets over $3 billion. Except as hereinafter set forth, 
compensation under this Agreement shall be calculated and accrued daily and 
the amounts of the daily accruals shall be paid monthly. Such calculations 
shall be made by applying 1/365ths of the annual rates to the Fund's net 
assets each day determined as of the close of business on that day or the 
last previous business day. If this Agreement becomes effective subsequent to 
the first day of a month or shall terminate before the last day of a month, 
compensation for that part of the month this Agreement is in effect shall be 
prorated in a manner consistent with the calculation of the fees as set forth 
above.

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

       7.  In the event the operating expenses of the Fund, including amounts
payable to the Investment Manager pursuant to paragraph 6 hereof, for any
fiscal year ending on a date on which this Agreement is in effect, exceed the
expense limitations applicable to the Fund imposed by state securities laws or
regulations thereunder, as such limitations may be raised or lowered from time
to time, the Investment Manager shall reduce its management fee to the extent of
such excess and, if required, pursuant to any such laws or regulations, will
reimburse the Fund for annual operating expenses in excess of any expense
limitation that may be applicable; provided, however, there shall be excluded
from such expenses the amount of any interest, taxes, brokerage commissions and
extraordinary expenses (including but not limited to legal claims and
liabilities and litigation costs and any indemnification related thereto) paid
or payable by the Fund. Such reduction, if any, shall be computed and accrued
daily, shall be settled on a monthly basis, and shall be based
 
                                       2
<PAGE>

upon the expense limitation applicable to the Fund as at the end of the last
business day of the month. Should two or more such expense limitations be
applicable as at the end of the last business day of the month, that expense
limitation which results in the largest reduction in the Investment Manager's
fee shall be applicable.
 
       For purposes of this provision, should any applicable expense 
limitation be based upon the gross income of the Fund, such gross income 
shall include, but not be limited to, interest on debt securities in the 
Fund's portfolio accrued to and including the last day of the Fund's fiscal 
year, and dividends declared on equity securities in the Fund's portfolio, 
the record dates for which fall on or prior to the last day of such fiscal 
year, but shall not include gains from the sale of securities.
 
        8.  The Investment Manager will use its best efforts in the 
supervision and management of the investment activities of the Fund, but in 
the absence of willful misfeasance, bad faith, gross negligence or reckless 
disregard of its obligations hereunder, the Investment Manager shall not be 
liable to the Fund or any of its investors for any error of judgment or 
mistake of law or for any act or omission by the Investment Manager or for 
any losses sustained by the Fund or its investors.
 
        9.  Nothing contained in this Agreement shall prevent the Investment 
Manager or any affiliated person of the Investment Manager from acting as 
investment adviser or manager for any other person, firm or corporation and 
shall not in any way bind or restrict the Investment Manager or any such 
affiliated person from buying, selling or trading any securities or 
commodities for their own accounts or for the account of others for whom they 
may be acting. Nothing in this Agreement shall limit or restrict the right of 
any Director, officer or employee of the Investment Manager to engage in any 
other business or to devote his or her time and attention in part to the 
management or other aspects of any other business whether of a similar or 
dissimilar nature.
 
      10.  This Agreement shall remain in effect until April 30, 1999 and 
from year to year thereafter provided such continuance is approved at least 
annually by the vote of holders of a majority, as defined in the Investment 
Company Act (the "Act"), of the outstanding voting securities of the Fund or 
by the Directors of the Fund; provided that in either event such continuance 
is also approved annually by the vote of a majority of the Directors of the 
Fund who are not parties to this Agreement or "interested persons" (as 
defined in the Act) of any such party, which vote must be cast in person at a 
meeting called for the purpose of voting on such approval; provided, however, 
that (a) the Fund may, at any time and without the payment of any penalty, 
terminate this Agreement upon thirty days' written notice to the Investment 
Manager, either by majority vote of the Directors of the Fund or by the vote 
of a majority of the outstanding voting securities of the Fund; (b) this 
Agreement shall immediately terminate in the event of its assignment (to the 
extent required by the Act and the rules thereunder) unless such automatic 
terminations shall be prevented by an exemptive order of the Securities and 
Exchange Commission; and (c) the Investment Manager may terminate this 
Agreement without payment of penalty on thirty days' written notice to the 
Fund. Any notice under this Agreement shall be given in writing, addressed 
and delivered, or mailed post-paid, to the other party at the principal 
office of such party.
 
      11.  This Agreement may be amended by the parties without the vote or 
consent of the shareholders of the Fund to supply any omission, to cure, 
correct or supplement any ambiguous, defective or inconsistent provision 
hereof, or if they deem it necessary to conform this Agreement to the 
requirements of applicable federal laws or regulations, but neither the Fund 
nor the Investment Manager shall be liable for failing to do so.
 
      12.  This Agreement shall be construed in accordance with the laws of 
the State of New York and the applicable provisions of the Act. To the extent 
the applicable law of the State of New York, or any of the provisions herein, 
conflicts with the applicable provisions of the Act, the latter shall control.
 
      13.  The Investment Manager and the Fund each agree that the name "Dean 
Witter," which comprises a component of the Fund's name, is a property right 
of Dean Witter Reynolds Inc. The Fund agrees and consents that (i) it will 
only use the name "Dean Witter" as a component of its name and for no other 
purpose, (ii) it will not purport to grant to any third party the right to 
use the name "Dean Witter" for any
 
                                       3

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

                               DEAN WITTER FUNDS
                             DISTRIBUTION AGREEMENT
 
    AGREEMENT made as of this 31st day of May, 1997 between each of the open-end
investment  companies to which Dean Witter  InterCapital Inc. acts as investment
manager, that are  listed on Schedule  A, as may  be amended from  time to  time
(each,  a "Fund"  and collectively, the  "Funds"), and  Dean Witter Distributors
Inc., a Delaware corporation (the "Distributor").
 
                              W I T N E S S E T H:
 
    WHEREAS, each Fund is registered as an open-end investment company under the
Investment Company Act of 1940,  as amended (the "1940 Act"),  and it is in  the
interest of each Fund to offer its shares for sale continuously, and
 
    WHEREAS,  each Fund and the Distributor wish to enter into an agreement with
each other with respect to the  continuous offering of each Fund's  transferable
shares, of $0.01 par value (the "Shares"), to commence on the date listed above,
in  order to promote the growth of  each Fund and facilitate the distribution of
its shares.
 
    NOW, THEREFORE, the parties agree as follows:
 
    SECTION 1.  APPOINTMENT OF THE DISTRIBUTOR.
 
    (a) Each Fund hereby appoints  the Distributor as the principal  underwriter
and  distributor of the Fund to sell Shares to the public on the terms set forth
in this Agreement and that Fund's prospectus and the Distributor hereby  accepts
such appointment and agrees to act hereunder. Each Fund, during the term of this
Agreement,  shall sell Shares  to the Distributor upon  the terms and conditions
set forth herein.
 
    (b) The Distributor  agrees to  purchase Shares,  as principal  for its  own
account,  from  each Fund  and to  sell  Shares as  principal to  investors, and
securities dealers, including Dean Witter Reynolds Inc. ("DWR"), an affiliate of
the Distributor, upon the terms described  herein and in that Fund's  prospectus
(the  "Prospectus")  and statement  of  additional information  included  in the
Fund's registration statement (the "Registration Statement") most recently filed
from time to time  with the Securities and  Exchange Commission (the "SEC")  and
effective under the Securities Act of 1933, as amended (the "1933 Act"), and the
1940 Act or as the Prospectus may be otherwise amended or supplemented and filed
with the SEC pursuant to Rule 497 under the 1933 Act.
 
    SECTION  2.   EXCLUSIVE  NATURE OF  DUTIES.   The  Distributor shall  be the
exclusive principal underwriter and  distributor of each  Fund, except that  the
exclusive  rights granted to the Distributor to  sell the Shares shall not apply
to  Shares  issued  by  each  Fund:  (i)  in  connection  with  the  merger   or
consolidation  of any other investment company  or personal holding company with
the Fund or the  acquisition by purchase or  otherwise of all (or  substantially
all)  the assets or the outstanding shares of any such company by the Fund; (ii)
pursuant to reinvestment of dividends  or capital gains distributions; or  (iii)
pursuant to the reinstatement privilege afforded redeeming shareholders.
 
    SECTION 3.  PURCHASE OF SHARES FROM EACH FUND.
 
    (a)  The Distributor shall have  the right to buy  from each Fund the Shares
needed, but  not more  than the  Shares needed  (except for  clerical errors  in
transmission),   to  fill  unconditional  orders  for  Shares  placed  with  the
Distributor by investors or securities dealers. The price which the  Distributor
shall  pay for  the Shares  so purchased from  the Fund  shall be  the net asset
value, determined as set forth in the Prospectus, used in determining the public
offering price on which such orders were based.
 
    (b) The Shares are to  be resold by the  Distributor at the public  offering
price  of Shares as set  forth in the Prospectus,  to investors or to securities
dealers, including DWR, who  have entered into  selected dealer agreements  with
the  Distributor upon  the terms  and conditions set  forth in  Section 7 hereof
("Selected Dealers").
 
                                       1
<PAGE>
    (c) Each Fund  shall have the  right to suspend  the sale of  the Shares  at
times  when  redemption is  suspended pursuant  to the  conditions set  forth in
Section (f) hereof. Each Fund shall also  have the right to suspend the sale  of
the  Shares if trading on the New York Stock Exchange shall have been suspended,
if a  banking  moratorium  shall have  been  declared  by federal  or  New  York
authorities,  or if there shall have  been some other extraordinary event which,
in the judgment of a Fund, makes it impracticable to sell its Shares.
 
    (d) Each Fund, or  any agent of  a Fund designated in  writing by the  Fund,
shall  be promptly  advised of  all purchase orders  for Shares  received by the
Distributor. Any order may be rejected by a Fund; provided, however, that a Fund
will not arbitrarily or without reasonable cause refuse to accept orders for the
purchase of Shares. The Distributor will confirm orders upon their receipt,  and
each  Fund (or its agent) upon receipt of payment therefor and instructions will
deliver share  certificates  for  such  Shares or  a  statement  confirming  the
issuance of Shares. Payment shall be made to the Fund in New York Clearing House
funds.  The Distributor agrees to cause such payment and such instructions to be
delivered promptly to the Fund (or its agent).
 
    (e) With respect to Shares sold  by any Selected Dealer, the Distributor  is
authorized to direct each Fund's transfer agent to receive instructions directly
from  the Selected  Dealer on  behalf of the  Distributor as  to registration of
Shares in the names of investors and  to confirm issuance of the Shares to  such
investors.  The Distributor is also authorized to instruct the transfer agent to
receive payment directly from the Selected Dealer on behalf of the  Distributor,
for  prompt transmittal to each  Fund's custodian, of the  purchase price of the
Shares. In such event the Distributor shall obtain from the Selected Dealer  and
maintain a record of such registration instructions and payments.
 
    SECTION 4.  REPURCHASE OR REDEMPTION OF SHARES.
 
    (a)  Any of the outstanding Shares of  a Fund may be tendered for redemption
at any time, and each Fund agrees to redeem its Shares so tendered in accordance
with the applicable provisions set forth in its Prospectus. The price to be paid
to redeem the Shares  shall be equal  to the net asset  value determined as  set
forth  in the Prospectus  less, in the case  of a Fund  whose Shares are offered
with a contingent deferred sales charge ("CDSC"), any applicable CDSC. Upon  any
redemption of Shares the Fund shall pay the total amount of the redemption price
in New York Clearing House funds in accordance with applicable provisions of the
Prospectus.
 
    (b)  In the case of  a Fund whose Shares are  offered with a front-end sales
charge, the redemption by a  Fund of any of its  Shares purchased by or  through
the Distributor will not affect the applicable front-end sales charge secured by
the  Distributor or  any Selected  Dealer in  the course  of the  original sale,
except that if any Shares are tendered for redemption within seven business days
after the date of the  confirmation of the original  purchase, the right to  the
applicable  front-end sales charge shall be forfeited by the Distributor and the
Selected Dealer which sold such Shares.
 
    (c) In the case of a Fund whose Shares are offered with a CDSC, the proceeds
of any redemption  of Shares  shall be  paid by each  Fund as  follows: (i)  any
applicable  CDSC shall be paid to the Distributor or to the Selected Dealer, or,
when applicable,  pursuant to  the  Rules of  the  Association of  the  National
Association  of Securities Dealers, Inc. ("NASD"), retained by the Fund and (ii)
the balance  shall  be paid  to  the redeeming  shareholders,  in each  case  in
accordance  with applicable  provisions of its  Prospectus in  New York Clearing
House funds. The Distributor is authorized to  direct a Fund to pay directly  to
the  Selected Dealer any CDSC payable by a Fund to the Distributor in respect of
Shares sold by the Selected Dealer to the redeeming shareholders.
 
    (d) The Distributor  is authorized,  as agent  for the  Fund, to  repurchase
Shares,  represented by a share certificate which  is delivered to any office of
the Distributor  in accordance  with  applicable provisions  set forth  in  each
Fund's Prospectus. The Distributor shall promptly transmit to the transfer agent
of  the Fund for  redemption all Shares  so delivered. The  Distributor shall be
responsible for the accuracy of instructions transmitted to the Fund's  transfer
agent in connection with all such repurchases.
 
    (e)  The Distributor  is authorized, as  agent for each  Fund, to repurchase
Shares held  in  a  shareholder's  account  with  a  Fund  for  which  no  share
certificate   has   been   issued,   upon   the   telephonic   request   of  the
 
                                       2
<PAGE>
shareholders, or at  the discretion  of the Distributor.  The Distributor  shall
promptly  transmit to the transfer  agent of the Fund,  for redemption, all such
orders for repurchase of Shares. Payment for Shares repurchased may be made by a
Fund to the  Distributor for  the account  of the  shareholder. The  Distributor
shall  be responsible for the accuracy of instructions transmitted to the Fund's
transfer agent in connection with all such repurchases.
 
    (f) Redemption of its Shares or payment by a Fund may be suspended at  times
when  the New York  Stock Exchange is  closed, when trading  on said Exchange is
restricted, when an emergency exists as a result of which disposal by a Fund  of
securities  owned by it  is not reasonably  practicable or it  is not reasonably
practicable for a  Fund fairly  to determine  the value  of its  net assets,  or
during any other period when the SEC, by order, so permits.
 
    (g)  With respect to its Shares tendered for redemption or repurchase by any
Selected Dealer on  behalf of its  customers, the Distributor  is authorized  to
instruct  the  transfer agent  of  a Fund  to  accept orders  for  redemption or
repurchase directly from the Selected Dealer on behalf of the Distributor and to
instruct the  Fund to  transmit payments  for such  redemptions and  repurchases
directly  to the Selected Dealer on behalf of the Distributor for the account of
the shareholder.  The Distributor  shall obtain  from the  Selected Dealer,  and
shall  maintain, a record of such  orders. The Distributor is further authorized
to obtain from the Fund, and shall  maintain, a record of payment made  directly
to the Selected Dealer on behalf of the Distributor.
 
    SECTION 5.  DUTIES OF THE FUND.
 
    (a)  Each Fund shall  furnish to the Distributor  copies of all information,
financial statements  and  other papers  which  the Distributor  may  reasonably
request for use in connection with the distribution of its Shares, including one
certified  copy, upon  request by the  Distributor, of  all financial statements
prepared by the Fund and examined  by independent accountants. Each Fund  shall,
at the expense of the Distributor, make available to the Distributor such number
of copies of its Prospectus as the Distributor shall reasonably request.
 
    (b)  Each Fund shall take,  from time to time,  but subject to the necessary
approval of its  shareholders, all  necessary action to  fix the  number of  its
authorized  Shares and to  register Shares under  the 1933 Act,  to the end that
there will  be  available  for sale  such  number  of Shares  as  investors  may
reasonably be expected to purchase.
 
    (c)  Each Fund  shall use  its best efforts  to pay  the filing  fees for an
appropriate number of its Shares  to be sold under  the securities laws of  such
states  as the Distributor and  the Fund may approve.  Any qualification to sell
its Shares in a state may be withheld, terminated or withdrawn by a Fund at  any
time  in its discretion.  As provided in  Section 8(c) hereof,  such filing fees
shall be paid  by the Fund.  The Distributor shall  furnish any information  and
other  material relating to its  affairs and activities as  may be required by a
Fund in connection with the sale of its Shares in any state.
 
    (d) Each  Fund  shall,  at  the expense  of  the  Distributor,  furnish,  in
reasonable  quantities upon request by the Distributor, copies of its annual and
interim reports.
 
    SECTION 6.  DUTIES OF THE DISTRIBUTOR.
 
    (a) The Distributor shall sell shares of each Fund through DWR and may  sell
shares  through other  securities dealers  and its  own Account  Executives, and
shall devote reasonable  time and  effort to promote  sales of  the Shares,  but
shall  not be obligated to  sell any specific number  of Shares. The services of
the Distributor  hereunder are  not  exclusive and  it  is understood  that  the
Distributor  may act  as principal  underwriter for  other registered investment
companies, so  long as  the  performance of  its  obligations hereunder  is  not
impaired  thereby. It is  also understood that  Selected Dealers, including DWR,
may also sell shares for other registered investment companies.
 
    (b)  Neither  the  Distributor  nor  any  Selected  Dealer  shall  give  any
information  or  make any  representations, other  than  those contained  in the
Registration  Statement  or   related  Prospectus  and   any  sales   literature
specifically approved by the appropriate Fund.
 
                                       3
<PAGE>
    (c)  The  Distributor agrees  that  it will  at  all times  comply  with the
applicable terms and limitations of the Rules of the Association of the NASD.
 
    SECTION 7.  SELECTED DEALERS AGREEMENTS.
 
    (a) The  Distributor shall  have the  right to  enter into  selected  dealer
agreements  with Selected Dealers  for the sale of  Shares. In making agreements
with Selected Dealers, the  Distributor shall act only  as principal and not  as
agent  for a Fund. Shares  sold to Selected Dealers shall  be for resale by such
dealers only at  the public  offering price set  forth in  the Prospectus.  With
respect to Funds whose Shares are offered with a front-end sales charge, in such
agreement  the  Distributor shall  have  the right  to  fix the  portion  of the
applicable front-end  sales  charge  which  may be  allocated  to  the  Selected
Dealers.
 
    (b)  Within the United  States, the Distributor shall  offer and sell Shares
only to Selected Dealers that are members in good standing of the NASD.
 
    (c) The Distributor shall adopt and  follow procedures, as approved by  each
Fund,  for the  confirmation of  sales of its  Shares to  investors and Selected
Dealers, the collection of amounts payable by investors and Selected Dealers  on
such  sales, and the cancellation of unsettled transactions, as may be necessary
to comply with the requirements of the NASD, as such requirements may from  time
to time exist.
 
    SECTION 8.  PAYMENT OF EXPENSES.
 
    (a)  Each Fund shall bear all costs and expenses of the Fund, including fees
and disbursements of legal counsel  including counsel to the  Directors/Trustees
of  each Fund who are not interested persons (as defined in the 1940 Act) of the
Fund or the  Distributor, and  independent accountants, in  connection with  the
preparation  and filing of any required Registration Statements and Prospectuses
and all  amendments  and supplements  thereto,  and the  expense  of  preparing,
printing,  mailing  and otherwise  distributing  prospectuses and  statements of
additional  information,  annual  or  interim  reports  or  proxy  materials  to
shareholders.
 
    (b)  The Distributor  shall bear all  expenses incurred by  it in connection
with its duties  and activities under  this Agreement including  the payment  to
Selected  Dealers of any sales commissions,  service fees and other expenses for
sales of a Fund's  Shares (except such expenses  as are specifically  undertaken
herein  by a  Fund) incurred  or paid  by Selected  Dealers, including  DWR. The
Distributor shall  bear  the  costs  and expenses  of  preparing,  printing  and
distributing  any  supplementary sales  literature  used by  the  Distributor or
furnished by it for use by Selected  Dealers in connection with the offering  of
the  Shares for  sale. Any expenses  of advertising incurred  in connection with
such offering will also be the  obligation of the Distributor. It is  understood
and agreed that, so long as a Fund's Plan of Distribution pursuant to Rule 12b-1
under  the  1940  Act ("Rule  12b-1  Plan")  continues in  effect,  any expenses
incurred by the Distributor hereunder may  be paid in accordance with the  terms
of such Rule 12b-1 Plan.
 
    (c)  Each Fund shall pay the filing  fees, and, if necessary or advisable in
connection therewith, bear  the cost and  expense of qualifying  each Fund as  a
broker  or dealer, in such states of the United States or other jurisdictions as
shall be  selected by  the Fund  and the  Distributor pursuant  to Section  5(c)
hereof  and the cost and  expenses payable to each  such state for continuing to
offer Shares  therein  until the  Fund  decides to  discontinue  selling  Shares
pursuant to Section 5(c) hereof.
 
    SECTION 9.  INDEMNIFICATION.
 
    (a)  Each Fund  shall indemnify and  hold harmless the  Distributor and each
person, if any, who controls the Distributor against any loss, liability, claim,
damage or expense (including the  reasonable cost of investigating or  defending
any  alleged loss,  liability, claim, damage  or expense  and reasonable counsel
fees incurred in connection therewith) arising by reason of any person acquiring
any Shares, which may be based upon the 1933 Act, or on any other statute or  at
common  law, on the ground that the Registration Statement or related Prospectus
and Statement  of Additional  Information,  as from  time  to time  amended  and
supplemented,  or  the annual  or  interim reports  to  shareholders of  a Fund,
includes an untrue statement  of a material  fact or omits  to state a  material
fact  required to be stated therein or necessary in order to make the statements
therein not misleading, unless such statement  or omission was made in  reliance
upon, and in
 
                                       4
<PAGE>
conformity with, information furnished to the Fund in connection therewith by or
on  behalf of  the Distributor; provided,  however, that  in no case  (i) is the
indemnity of a Fund in favor of the Distributor and any such controlling persons
to be deemed to protect the Distributor or any such controlling persons  thereof
against any liability to a Fund or its security holders to which the Distributor
or  any such controlling persons would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence  in the performance of its duties  or
by  reason  of  reckless disregard  of  its  obligations and  duties  under this
Agreement; or  (ii)  is  a Fund  to  be  liable under  its  indemnity  agreement
contained  in  this  paragraph  with  respect  to  any  claim  made  against the
Distributor or any such controlling persons, unless the Distributor or any  such
controlling persons, as the case may be, shall have notified the Fund in writing
within  a reasonable time after the summons  or other first legal process giving
information of  the  nature  of  the  claim shall  have  been  served  upon  the
Distributor  or  uch  controlling  persons (or  after  the  Distributor  or such
controlling persons shall have received notice of such service on any designated
agent), but failure to notify  the Fund of any such  claim shall not relieve  it
from  any liability which it may have to  the person against whom such action is
brought otherwise than on account of  its indemnity agreement contained in  this
paragraph.  Each Fund will be entitled to  participate at its own expense in the
defense, or, if it so elects, to assume the defense, of any such suit brought to
enforce any such liability,  but if a  Fund elects to  assume the defense,  such
defense  shall be  conducted by  counsel chosen  by it  and satisfactory  to the
Distributor or such controlling  person or persons,  defendant or defendants  in
the  suit. In the event the  Fund elects to assume the  defense of any such suit
and retain such counsel, the Distributor or such controlling person or  persons,
defendant  or defendants in  the suit, shall  bear the fees  and expenses of any
additional counsel retained by  them, but, in  case the Fund  does not elect  to
assume  the defense of any such suit,  it will reimburse the Distributor or such
controlling person or  persons, defendant  or defendants  in the  suit, for  the
reasonable  fees and expenses of  any counsel retained by  them. Each Fund shall
promptly notify  the  Distributor  of  the commencement  of  any  litigation  or
proceedings  against  it  or  any  of  its  officers  or  Directors/Trustees  in
connection with the issuance or sale of the Shares.
 
    (b)  (i)  The Distributor shall  indemnify and hold  harmless each Fund  and
each  of  its Directors/  Trustees and  officers  and each  person, if  any, who
controls the  Fund  against  any  loss, liability,  claim,  damage,  or  expense
described in the indemnity contained in subsection (a) of this Section, but only
with respect to statements or omissions made in reliance upon, and in conformity
with,  information  furnished  to a  Fund  in writing  by  or on  behalf  of the
Distributor for use  in connection  with the Registration  Statement or  related
Prospectus  and  Statement  of  Additional Information,  as  from  time  to time
amended, or the annual or interim reports to shareholders.
 
        (ii) The Distributor  shall indemnify  and hold harmless  each Fund  and
each  Fund's  transfer agent,  individually and  in its  capacity as  the Fund's
transfer agent, from and against any claims, damages and liabilities which arise
as a result of actions taken pursuant to instructions from, or on behalf of, the
Distributor to: (1) redeem  all or a  part of shareholder  accounts in the  Fund
pursuant  to Section 4(g) hereof and pay the proceeds to, or as directed by, the
Distributor for the account  of each shareholder whose  Shares are so  redeemed;
and  (2) register Shares in the names of investors, confirm the issuance thereof
and receive payment therefor pursuant to Section 3(e) hereof.
 
       (iii) In case any action shall be brought against a Fund or any person so
indemnified by this  Section 9(b) in  respect of which  indemnity may be  sought
against  the Distributor, the Distributor shall have the rights and duties given
to a Fund, and the Fund and each person so indemnified shall have the rights and
duties given to  the Distributor, by  the provisions of  subsection (a) of  this
Section 9.
 
    (c)  If the indemnification provided for in this Section 9 is unavailable or
insufficient to hold harmless an indemnified  party under subsection (a) or  (b)
above  in respect  of any losses,  claims, damages, liabilities  or expenses (or
actions in respect thereof)  referred to herein,  then each indemnifiying  party
shall  contribute to the amount  paid or payable by  such indemnified party as a
result of such losses, claims, damages,  liabilities or expenses (or actions  in
respect  thereof) in such  proportion as is appropriate  to reflect the relative
benefits received by a  Fund on the  one hand and the  Distributor on the  other
from  the offering of  the Shares. If,  however, the allocation  provided by the
immediately preceding sentence  is not  permitted by applicable  law, then  each
indemnifying  party  shall contribute  to such  amount paid  or payable  by such
indemnified party in
 
                                       5
<PAGE>
such proportion as is appropriate to reflect not only such relative benefits but
also the relative fault  of a Fund on  the one hand and  the Distributor on  the
other  in connection  with the  statements or  omissions which  resulted in such
losses,  claims,  damages,  liabilities  or  expenses  (or  actions  in  respect
thereof),  as well as any other  relevant equitable considerations. The relative
benefits received by a  Fund on the  one hand and the  Distributor on the  other
shall  be deemed to be in the same proportion as the total net proceeds from the
offering (before deducting  expenses) received  by the  Fund bear  to the  total
compensation  received by  the Distributor,  in each  case as  set forth  in the
Prospectus. The relative fault shall be determined by reference to, among  other
things, whether the untrue or alleged untrue statement of a material fact or the
omission  or alleged  omission to state  a material fact  relates to information
supplied by  a  Fund  or  the Distributor  and  the  parties'  relative  intent,
knowledge,  access to  information and  opportunity to  correct or  prevent such
statement or omission. Each Fund and the Distributor agree that it would not  be
just  and equitable if contribution were determined by pro rata allocation or by
any other method of  allocation which does not  take into account the  equitable
considerations  referred to above. The amount  paid or payable by an indemnified
party as a result  of the losses, claims,  damages, liabilities or expenses  (or
actions  in respect thereof)  referred to above  shall be deemed  to include any
legal or  other  expenses  reasonably  incurred by  such  indemnified  party  in
connection  with investigating or defending  any such claim. Notwithstanding the
provisions of this  subsection (c),  the Distributor  shall not  be required  to
contribute  any amount in excess of the amount by which the total price at which
the Shares distributed by it  to the public were  offered to the public  exceeds
the  amount of any damages which it has otherwise been required to pay by reason
of such untrue or alleged untrue  statement or omission or alleged omission.  No
person  guilty of  fraudulent misrepresentation  (within the  meaning of Section
11(f) of the 1933 Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation.
 
    SECTION 10.   DURATION AND TERMINATION  OF THIS AGREEMENT.   This  Agreement
shall become effective with respect to a Fund as of the date first above written
and shall remain in force until April 30, 1998, and thereafter, but only so long
as  such continuance is specifically approved at least annually by (i) the Board
of Directors/Trustees  of  each Fund,  or  by the  vote  of a  majority  of  the
outstanding  voting securities of the Fund, cast in person or by proxy, and (ii)
a majority of those Directors/Trustees who are not parties to this Agreement  or
interested  persons  of  any such  party  and  who have  no  direct  or indirect
financial interest in  this Agreement  or in the  operation of  the Fund's  Rule
12b-1  Plan or  in any agreement  related thereto,  cast in person  at a meeting
called for the purpose of voting upon such approval.
 
    This Agreement may  be terminated  at any time  without the  payment of  any
penalty,   by  the  Directors/Trustees  of  a  Fund,  by  a  majority  of  the
Directors/Trustees of a Fund who are not interested persons of the Fund and  who
have no direct or indirect financial interest in this Agreement, or by vote of a
majority  of the outstanding voting securities of a Fund, or by the Distributor,
on sixty  days'  written  notice  to  the  other  party.  This  Agreement  shall
automatically terminate in the event of its assignment.
 
    The  terms  "vote  of  a majority  of  the  outstanding  voting securities,"
"assignment" and "interested person,"  when used in  this Agreement, shall  have
the respective meanings specified in the 1940 Act.
 
    SECTION 11.  AMENDMENTS OF THIS AGREEMENT.  This Agreement may be amended by
the  parties  only  if  such  amendment  is  specifically  approved  by  (i) the
Directors/Trustees of a Fund, or by the vote of a majority of outstanding voting
securities of a Fund, and (ii) a majority of those Directors/Trustees of a  Fund
who  are not parties to  this Agreement or interested  persons of any such party
and who have no direct  or indirect financial interest  in this Agreement or  in
any Agreement related to the Fund's Rule 12b-1 Plan, cast in person at a meeting
called for the purpose of voting on such approval.
 
    SECTION  12.   ADDITIONAL FUNDS.   If  at any  time another  Fund desires to
appoint the Distributor as its principal underwriter and distributor under  this
Agreement,  it shall  notify the Distributor  in writing. If  the Distributor is
willing to serve as the Fund's principal underwriter and distributor under  this
Agreement,  it shall notify the Fund in writing, whereupon such other Fund shall
become a Fund hereunder.
 
                                       6
<PAGE>
    SECTION 13.  GOVERNING LAW.  This Agreement shall be construed in accordance
with the law of the State of New York and the applicable provisions of the  1940
Act.  To the extent the applicable  law of the State of  New York, or any of the
provisions herein, conflicts with the applicable provisions of the 1940 Act, the
latter shall control.
 
    SECTION 14.  PERSONAL LIABILITY.  With respect to any Fund that is organized
as an  unincorporated business  trust  under the  laws  of the  Commonwealth  of
Massachusetts,  its Declaration of the Trust  (each, a "Declaration") is on file
in the  office of  the  Secretary of  the  Commonwealth of  Massachusetts.  Each
Declaration  provides that the name of the Fund refers to the Trustees under the
Declaration collectively as Trustees, but not as individuals or personally;  and
no Trustee, shareholder, officer, employee or agent of any Fund shall be held to
any  personal liability, nor shall  resort be had to  their private property for
the satisfaction of any obligation or claim or otherwise, in connection with the
affairs of any Fund, but the Trust Estate only shall be liable.
 
    IN WITNESS  WHEREOF, the  parties hereto  have executed  and delivered  this
Agreement as of the day and year first written in New York, New York.

                             DISTRIBUTION AGREEMENT
 
    AGREEMENT made as of this 28th day of July, 1997 between each of the
open-end investment companies to which Dean Witter InterCapital Inc. acts as
investment manager, that are listed on Schedule A, as may be amended from time
to time (each, a "Fund" and collectively, the "Funds"), and Dean Witter
Distributors Inc., a Delaware corporation (the "Distributor").
 
                              W I T N E S S E T H:
 
    WHEREAS, each Fund is registered as an open-end investment company under the
Investment Company Act of 1940, as amended (the "1940 Act"), and it is in the
interest of each Fund to offer its shares for sale continuously, and
 
    WHEREAS, each Fund and the Distributor wish to enter into an agreement with
each other with respect to the continuous offering of each Fund's transferable
shares, of $0.01 par value (the "Shares"), to commence on the date listed above,
in order to promote the growth of each Fund and facilitate the distribution of
its shares.
 
    NOW, THEREFORE, the parties agree as follows:
 
    SECTION 1.  APPOINTMENT OF THE DISTRIBUTOR.
 
    (a) Each Fund hereby appoints the Distributor as the principal underwriter
and distributor of the Fund to sell Shares to the public on the terms set forth
in this Agreement and that Fund's prospectus and the Distributor hereby accepts
such appointment and agrees to act hereunder. Each Fund, during the term of this
Agreement, shall sell Shares to the Distributor upon the terms and conditions
set forth herein.
 
    (b) The Distributor agrees to purchase Shares, as principal for its own
account, from each Fund and to sell Shares as principal to investors, and
securities dealers, including Dean Witter Reynolds Inc. ("DWR"), an affiliate of
the Distributor, upon the terms described herein and in that Fund's prospectus
(the "Prospectus") and statement of additional information included in the
Fund's registration statement (the "Registration Statement") most recently filed
from time to time with the Securities and Exchange Commission (the "SEC") and
effective under the Securities Act of 1933, as amended (the "1933 Act"), and the
1940 Act or as the Prospectus may be otherwise amended or supplemented and filed
with the SEC pursuant to Rule 497 under the 1933 Act.
 
    SECTION 2.  EXCLUSIVE NATURE OF DUTIES.  The Distributor shall be the
exclusive principal underwriter and distributor of each Fund, except that the
exclusive rights granted to the Distributor to sell the Shares shall not apply
to Shares issued by each Fund: (i) in connection with the merger or
consolidation of any other investment company or personal holding company with
the Fund or the acquisition by purchase or otherwise of all (or substantially
all) the assets or the outstanding shares of any such company by the Fund; (ii)
pursuant to reinvestment of dividends or capital gains distributions; or (iii)
pursuant to the reinstatement privilege afforded redeeming shareholders.
 
    SECTION 3.  PURCHASE OF SHARES FROM EACH FUND.  The Shares are offered in
four classes (each, a "Class"), as described in the Prospectus, as amended or
supplemented from time to time.
 
    (a) The Distributor shall have the right to buy from each Fund the Shares of
the particular class needed, but not more than the Shares needed (except for
clerical errors in transmission), to fill unconditional orders for Shares of the
applicable class placed with the Distributor by investors or securities dealers.
The price which the Distributor shall pay for the Shares so purchased from the
Fund shall be the net asset value, determined as set forth in the Prospectus,
used in determining the public offering price on which such orders were based.
 
    (b) The Shares are to be resold by the Distributor at the public offering
price of Shares of the applicable class as set forth in the Prospectus, to
investors or to securities dealers, including DWR, who
 
                                       1
<PAGE>
have entered into selected dealer agreements with the Distributor upon the terms
and conditions set forth in Section 7 hereof ("Selected Dealers").
 
    (c) Each Fund shall have the right to suspend the sale of the Shares at
times when redemption is suspended pursuant to the conditions set forth in
Section 4(f) hereof. Each Fund shall also have the right to suspend the sale of
the Shares if trading on the New York Stock Exchange shall have been suspended,
if a banking moratorium shall have been declared by federal or New York
authorities, or if there shall have been some other extraordinary event which,
in the judgment of a Fund, makes it impracticable to sell its Shares.
 
    (d) Each Fund, or any agent of a Fund designated in writing by the Fund,
shall be promptly advised of all purchase orders for Shares received by the
Distributor. Any order may be rejected by a Fund; provided, however, that a Fund
will not arbitrarily or without reasonable cause refuse to accept orders for the
purchase of Shares. The Distributor will confirm orders upon their receipt, and
each Fund (or its agent) upon receipt of payment therefor and instructions will
deliver share certificates for such Shares or a statement confirming the
issuance of Shares. Payment shall be made to the Fund in New York Clearing House
funds. The Distributor agrees to cause such payment and such instructions to be
delivered promptly to the Fund (or its agent).
 
    (e) With respect to Shares sold by any Selected Dealer, the Distributor is
authorized to direct each Fund's transfer agent to receive instructions directly
from the Selected Dealer on behalf of the Distributor as to registration of
Shares in the names of investors and to confirm issuance of the Shares to such
investors. The Distributor is also authorized to instruct the transfer agent to
receive payment directly from the Selected Dealer on behalf of the Distributor,
for prompt transmittal to each Fund's custodian, of the purchase price of the
Shares. In such event the Distributor shall obtain from the Selected Dealer and
maintain a record of such registration instructions and payments.
 
    SECTION 4.  REPURCHASE OR REDEMPTION OF SHARES.
 
    (a) Any of the outstanding Shares of a Fund may be tendered for redemption
at any time, and each Fund agrees to redeem its Shares so tendered in accordance
with the applicable provisions set forth in its Prospectus. The price to be paid
to redeem the Shares shall be equal to the net asset value determined as set
forth in the Prospectus less any applicable contingent deferred sales charge
("CDSC"). Upon any redemption of Shares the Fund shall pay the total amount of
the redemption price in New York Clearing House funds in accordance with
applicable provisions of the Prospectus.
 
    (b) The redemption by a Fund of any of its Class A Shares purchased by or
through the Distributor will not affect the applicable front-end sales charge
secured by the Distributor or any Selected Dealer in the course of the original
sale, except that if any Class A Shares are tendered for redemption within seven
business days after the date of the confirmation of the original purchase, the
right to the applicable front-end sales charge shall be forfeited by the
Distributor and the Selected Dealer which sold such Shares.
 
    (c) The proceeds of any redemption of Class A, Class B or Class C Shares
shall be paid by each Fund as follows: (i) any applicable CDSC shall be paid to
the Distributor or to the Selected Dealer, or, when applicable, pursuant to the
Rules of the Association of the National Association of Securities Dealers, Inc.
("NASD"), retained by the Fund and (ii) the balance shall be paid to the
redeeming shareholders, in each case in accordance with applicable provisions of
its Prospectus in New York Clearing House funds. The Distributor is authorized
to direct a Fund to pay directly to the Selected Dealer any CDSC payable by a
Fund to the Distributor in respect of Class A, Class B, or Class C Shares sold
by the Selected Dealer to the redeeming shareholders.
 
    (d) The Distributor is authorized, as agent for the Fund, to repurchase
Shares, represented by a share certificate which is delivered to any office of
the Distributor in accordance with applicable provisions set forth in each
Fund's Prospectus. The Distributor shall promptly transmit to the transfer agent
of the Fund for redemption all Shares so delivered. The Distributor shall be
responsible for the accuracy of instructions transmitted to the Fund's transfer
agent in connection with all such repurchases.
 
                                       2
<PAGE>
    (e) The Distributor is authorized, as agent for each Fund, to repurchase
Shares held in a shareholder's account with a Fund for which no share
certificate has been issued, upon the telephonic request of the shareholders, or
at the discretion of the Distributor. The Distributor shall promptly transmit to
the transfer agent of the Fund, for redemption, all such orders for repurchase
of Shares. Payment for Shares repurchased may be made by a Fund to the
Distributor for the account of the shareholder. The Distributor shall be
responsible for the accuracy of instructions transmitted to the Fund's transfer
agent in connection with all such repurchases.
 
    (f) Redemption of its Shares or payment by a Fund may be suspended at times
when the New York Stock Exchange is closed, when trading on said Exchange is
restricted, when an emergency exists as a result of which disposal by a Fund of
securities owned by it is not reasonably practicable or it is not reasonably
practicable for a Fund fairly to determine the value of its net assets, or
during any other period when the SEC, by order, so permits.
 
    (g) With respect to its Shares tendered for redemption or repurchase by any
Selected Dealer on behalf of its customers, the Distributor is authorized to
instruct the transfer agent of a Fund to accept orders for redemption or
repurchase directly from the Selected Dealer on behalf of the Distributor and to
instruct the Fund to transmit payments for such redemptions and repurchases
directly to the Selected Dealer on behalf of the Distributor for the account of
the shareholder. The Distributor shall obtain from the Selected Dealer, and
shall maintain, a record of such orders. The Distributor is further authorized
to obtain from the Fund, and shall maintain, a record of payment made directly
to the Selected Dealer on behalf of the Distributor.
 
    SECTION 5.  DUTIES OF THE FUND.
 
    (a) Each Fund shall furnish to the Distributor copies of all information,
financial statements and other papers which the Distributor may reasonably
request for use in connection with the distribution of its Shares, including one
certified copy, upon request by the Distributor, of all financial statements
prepared by the Fund and examined by independent accountants. Each Fund shall,
at the expense of the Distributor, make available to the Distributor such number
of copies of its Prospectus as the Distributor shall reasonably request.
 
    (b) Each Fund shall take, from time to time, but subject to the necessary
approval of its shareholders, all necessary action to fix the number of its
authorized Shares and to register Shares under the 1933 Act, to the end that
there will be available for sale such number of Shares as investors may
reasonably be expected to purchase.
 
    (c) Each Fund shall use its best efforts to pay the filing fees for an
appropriate number of its Shares to be sold under the securities laws of such
states as the Distributor and the Fund may approve. Any qualification to sell
its Shares in a state may be withheld, terminated or withdrawn by a Fund at any
time in its discretion. As provided in Section 8(c) hereof, such filing fees
shall be paid by the Fund. The Distributor shall furnish any information and
other material relating to its affairs and activities as may be required by a
Fund in connection with the sale of its Shares in any state.
 
    (d) Each Fund shall, at the expense of the Distributor, furnish, in
reasonable quantities upon request by the Distributor, copies of its annual and
interim reports.
 
    SECTION 6.  DUTIES OF THE DISTRIBUTOR.
 
    (a) The Distributor shall sell shares of each Fund through DWR and may sell
shares through other securities dealers and its own Account Executives, and
shall devote reasonable time and effort to promote sales of the Shares, but
shall not be obligated to sell any specific number of Shares. The services of
the Distributor hereunder are not exclusive and it is understood that the
Distributor may act as principal underwriter for other registered investment
companies, so long as the performance of its obligations hereunder is not
impaired thereby. It is also understood that Selected Dealers, including DWR,
may also sell shares for other registered investment companies.
 
                                       3
<PAGE>
    (b) Neither the Distributor nor any Selected Dealer shall give any
information or make any representations, other than those contained in the
Registration Statement or related Prospectus and any sales literature
specifically approved by the appropriate Fund.
 
    (c) The Distributor agrees that it will at all times comply with the
applicable terms and limitations of the Rules of the Association of the NASD.
 
    SECTION 7.  SELECTED DEALERS AGREEMENTS.
 
    (a) The Distributor shall have the right to enter into selected dealer
agreements with Selected Dealers for the sale of Shares. In making agreements
with Selected Dealers, the Distributor shall act only as principal and not as
agent for a Fund. Shares sold to Selected Dealers shall be for resale by such
dealers only at the public offering price set forth in the Prospectus. With
respect to Class A Shares, in such agreement the Distributor shall have the
right to fix the portion of the applicable front-end sales charge which may be
allocated to the Selected Dealers.
 
    (b) Within the United States, the Distributor shall offer and sell Shares
only to Selected Dealers that are members in good standing of the NASD.
 
    (c) The Distributor shall adopt and follow procedures, as approved by each
Fund, for the confirmation of sales of its Shares to investors and Selected
Dealers, the collection of amounts payable by investors and Selected Dealers on
such sales, and the cancellation of unsettled transactions, as may be necessary
to comply with the requirements of the NASD, as such requirements may from time
to time exist.
 
    SECTION 8.  PAYMENT OF EXPENSES.
 
    (a) Each Fund shall bear all costs and expenses of the Fund, including fees
and disbursements of legal counsel including counsel to the Directors/Trustees
of each Fund who are not interested persons (as defined in the 1940 Act) of the
Fund or the Distributor, and independent accountants, in connection with the
preparation and filing of any required Registration Statements and Prospectuses
and all amendments and supplements thereto, and the expense of preparing,
printing, mailing and otherwise distributing prospectuses and statements of
additional information, annual or interim reports or proxy materials to
shareholders.
 
    (b) The Distributor shall bear all expenses incurred by it in connection
with its duties and activities under this Agreement including the payment to
Selected Dealers of any sales commissions, service fees and other expenses for
sales of a Fund's Shares (except such expenses as are specifically undertaken
herein by a Fund) incurred or paid by Selected Dealers, including DWR. The
Distributor shall bear the costs and expenses of preparing, printing and
distributing any supplementary sales literature used by the Distributor or
furnished by it for use by Selected Dealers in connection with the offering of
the Shares for sale. Any expenses of advertising incurred in connection with
such offering will also be the obligation of the Distributor. It is understood
and agreed that, so long as a Fund's Plan of Distribution pursuant to Rule 12b-1
under the 1940 Act ("Rule 12b-1 Plan") continues in effect, any expenses
incurred by the Distributor hereunder may be paid in accordance with the terms
of such Rule 12b-1 Plan.
 
    (c) Each Fund shall pay the filing fees, and, if necessary or advisable in
connection therewith, bear the cost and expense of qualifying each Fund as a
broker or dealer, in such states of the United States or other jurisdictions as
shall be selected by the Fund and the Distributor pursuant to Section 5(c)
hereof and the cost and expenses payable to each such state for continuing to
offer Shares therein until the Fund decides to discontinue selling Shares
pursuant to Section 5(c) hereof.
 
    SECTION 9.  INDEMNIFICATION.
 
    (a) Each Fund shall indemnify and hold harmless the Distributor and each
person, if any, who controls the Distributor against any loss, liability, claim,
damage or expense (including the reasonable cost of investigating or defending
any alleged loss, liability, claim, damage or expense and reasonable counsel
fees incurred in connection therewith) arising by reason of any person acquiring
any Shares, which may be based upon the 1933 Act, or on any other statute or at
common law, on the ground that the Registration Statement or related Prospectus
and Statement of Additional Information, as from time to time amended
 
                                       4
<PAGE>
and supplemented, or the annual or interim reports to shareholders of a Fund,
includes an untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary in order to make the statements
therein not misleading, unless such statement or omission was made in reliance
upon, and in conformity with, information furnished to the Fund in connection
therewith by or on behalf of the Distributor; provided, however, that in no case
(i) is the indemnity of a Fund in favor of the Distributor and any such
controlling persons to be deemed to protect the Distributor or any such
controlling persons thereof against any liability to a Fund or its security
holders to which the Distributor or any such controlling persons would otherwise
be subject by reason of willful misfeasance, bad faith or gross negligence in
the performance of its duties or by reason of reckless disregard of its
obligations and duties under this Agreement; or (ii) is a Fund to be liable
under its indemnity agreement contained in this paragraph with respect to any
claim made against the Distributor or any such controlling persons, unless the
Distributor or any such controlling persons, as the case may be, shall have
notified the Fund in writing within a reasonable time after the summons or other
first legal process giving information of the nature of the claim shall have
been served upon the Distributor or uch controlling persons (or after the
Distributor or such controlling persons shall have received notice of such
service on any designated agent), but failure to notify the Fund of any such
claim shall not relieve it from any liability which it may have to the person
against whom such action is brought otherwise than on account of its indemnity
agreement contained in this paragraph. Each Fund will be entitled to participate
at its own expense in the defense, or, if it so elects, to assume the defense,
of any such suit brought to enforce any such liability, but if a Fund elects to
assume the defense, such defense shall be conducted by counsel chosen by it and
satisfactory to the Distributor or such controlling person or persons, defendant
or defendants in the suit. In the event the Fund elects to assume the defense of
any such suit and retain such counsel, the Distributor or such controlling
person or persons, defendant or defendants in the suit, shall bear the fees and
expenses of any additional counsel retained by them, but, in case the Fund does
not elect to assume the defense of any such suit, it will reimburse the
Distributor or such controlling person or persons, defendant or defendants in
the suit, for the reasonable fees and expenses of any counsel retained by them.
Each Fund shall promptly notify the Distributor of the commencement of any
litigation or proceedings against it or any of its officers or
Directors/Trustees in connection with the issuance or sale of the Shares.
 
    (b) (i) The Distributor shall indemnify and hold harmless each Fund and each
of its Directors/ Trustees and officers and each person, if any, who controls
the Fund against any loss, liability, claim, damage, or expense described in the
indemnity contained in subsection (a) of this Section, but only with respect to
statements or omissions made in reliance upon, and in conformity with,
information furnished to a Fund in writing by or on behalf of the Distributor
for use in connection with the Registration Statement or related Prospectus and
Statement of Additional Information, as from time to time amended, or the annual
or interim reports to shareholders.
 
        (ii) The Distributor shall indemnify and hold harmless each Fund and
each Fund's transfer agent, individually and in its capacity as the Fund's
transfer agent, from and against any claims, damages and liabilities which arise
as a result of actions taken pursuant to instructions from, or on behalf of, the
Distributor to: (1) redeem all or a part of shareholder accounts in the Fund
pursuant to Section 4(g) hereof and pay the proceeds to, or as directed by, the
Distributor for the account of each shareholder whose Shares are so redeemed;
and (2) register Shares in the names of investors, confirm the issuance thereof
and receive payment therefor pursuant to Section 3(e) hereof.
 
        (iii) In case any action shall be brought against a Fund or any person
so indemnified by this Section 9(b) in respect of which indemnity may be sought
against the Distributor, the Distributor shall have the rights and duties given
to a Fund, and the Fund and each person so indemnified shall have the rights and
duties given to the Distributor, by the provisions of subsection (a) of this
Section 9.
 
    (c) If the indemnification provided for in this Section 9 is unavailable or
insufficient to hold harmless an indemnified party under subsection (a) or (b)
above in respect of any losses, claims, damages, liabilities or expenses (or
actions in respect thereof) referred to herein, then each indemnifiying party
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages, liabilities or expenses (or actions in
respect thereof) in such proportion as is appropriate to reflect the relative
benefits received by a Fund on the one hand and the Distributor on the other
from the
 
                                       5
<PAGE>
offering of the Shares. If, however, the allocation provided by the immediately
preceding sentence is not permitted by applicable law, then each indemnifying
party shall contribute to such amount paid or payable by such indemnified party
in such proportion as is appropriate to reflect not only such relative benefits
but also the relative fault of a Fund on the one hand and the Distributor on the
other in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or expenses (or actions in respect
thereof), as well as any other relevant equitable considerations. The relative
benefits received by a Fund on the one hand and the Distributor on the other
shall be deemed to be in the same proportion as the total net proceeds from the
offering (before deducting expenses) received by the Fund bear to the total
compensation received by the Distributor, in each case as set forth in the
Prospectus. The relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by a Fund or the Distributor and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. Each Fund and the Distributor agree that it would not be
just and equitable ifcontribution were determined by pro rata allocation or by
any other method of allocation which does not take into account the equitable
considerations referred to above. The amount paid or payable by an indemnified
party as a result of the losses, claims, damages, liabilities or expenses (or
actions in respect thereof) referred to above shall be deemed to include any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such claim. Notwithstanding the
provisions of this subsection (c), the Distributor shall not be required to
contribute any amount in excess of the amount by which the total price at which
the Shares distributed by it to the public were offered to the public exceeds
the amount of any damages which it has otherwise been required to pay by reason
of such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the 1933 Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation.
 
    SECTION 10.  DURATION AND TERMINATION OF THIS AGREEMENT.  This Agreement
shall become effective with respect to a Fund as of the date first above written
and shall remain in force until April 30, 1998, and thereafter, but only so long
as such continuance is specifically approved at least annually by (i) the Board
of Directors/Trustees of each Fund, or by the vote of a majority of the
outstanding voting securities of the Fund, cast in person or by proxy, and (ii)
a majority of those Directors/Trustees who are not parties to this Agreement or
interested persons of any such party and who have no direct or indirect
financial interest in this Agreement or in the operation of the Fund's Rule
12b-1 Plan or in any agreement related thereto, cast in person at a meeting
called for the purpose of voting upon such approval.
 
    This Agreement may be terminated at any time without the payment of any
penalty, by the Directors/ Trustees of a Fund, by a majority of the
Directors/Trustees of a Fund who are not interested persons of the Fund and who
have no direct or indirect financial interest in this Agreement, or by vote of a
majority of the outstanding voting securities of a Fund, or by the Distributor,
on sixty days' written notice to the other party. This Agreement shall
automatically terminate in the event of its assignment.
 
    The terms "vote of a majority of the outstanding voting securities,"
"assignment" and "interested person," when used in this Agreement, shall have
the respective meanings specified in the 1940 Act.
 
    SECTION 11.  AMENDMENTS OF THIS AGREEMENT.  This Agreement may be amended by
the parties only if such amendment is specifically approved by (i) the
Directors/Trustees of a Fund, or by the vote of a majority of outstanding voting
securities of a Fund, and (ii) a majority of those Directors/Trustees of a Fund
who are not parties to this Agreement or interested persons of any such party
and who have no direct or indirect financial interest in this Agreement or in
any Agreement related to the Fund's Rule 12b-1 Plan, cast in person at a meeting
called for the purpose of voting on such approval.
 
    SECTION 12.  ADDITIONAL FUNDS.  If at any time another Fund desires to
appoint the Distributor as its principal underwriter and distributor under this
Agreement, it shall notify the Distributor in writing. If the Distributor is
willing to serve as the Fund's principal underwriter and distributor under this
Agreement, it shall notify the Fund in writing, whereupon such other Fund shall
become a Fund hereunder.
 
    SECTION 13.  GOVERNING LAW.  This Agreement shall be construed in accordance
with the law of the State of New York and the applicable provisions of the 1940
Act. To the extent the applicable law of the
 
                                       6
<PAGE>
State of New York, or any of the provisions herein, conflicts with the
applicable provisions of the 1940 Act, the latter shall control.
 
    SECTION 14.  PERSONAL LIABILITY.  With respect to any Fund that is organized
as an unincorporated business trust under the laws of the Commonwealth of
Massachusetts, its Declaration of the Trust (each, a "Declaration") is on file
in the office of the Secretary of the Commonwealth of Massachusetts. Each
Declaration provides that the name of the Fund refers to the Trustees under the
Declaration collectively as Trustees, but not as individuals or personally; and
no Trustee, shareholder, officer, employee or agent of any Fund shall be held to
any personal liability, nor shall resort be had to their private property for
the satisfaction of any obligation or claim or otherwise, in connection with the
affairs of any Fund, but the Trust Estate only shall be liable.
 
    IN WITNESS WHEREOF, the parties hereto have executed and delivered this
Agreement as of the day and year first written in New York, New York.

                 PLAN OF DISTRIBUTION PURSUANT TO RULE 12b-1 
                                      OF 
                    DEAN WITTER HIGH YIELD SECURITIES INC. 

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

   WHEREAS, the Fund desires to adopt a Plan of Distribution pursuant to Rule 
12b-1 under the Act, and the Directors have determined that there is a 
reasonable likelihood that adoption of the Plan of Distribution will benefit 
the Fund and its shareholders; and 

   WHEREAS, the Fund and Dean Witter Distributors, Inc. (the "Distributor") 
have entered into a separate Distribution Agreement dated as of July 28, 
1997, pursuant to which the Fund has employed the Distributor in such 
capacity during the continuous offering of shares of the Fund. 

   NOW, THEREFORE, the Fund hereby adopts, and the Distributor hereby agrees 
to the terms of, this Plan of Distribution (the "Plan") in accordance with 
Rule 12b-1 under the Act on the following terms and conditions with respect 
to the Class A, Class B and Class C shares of the Fund: 

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

   1(a)(ii). The Fund is hereby authorized to reimburse the Distributor, Dean 
Witter Reynolds Inc. ("DWR"), its affiliates and other broker-dealers for 
distribution expenses incurred by them specifically on behalf of Class A and 
Class C shares of the Fund. Reimbursement will be made through payments at 
the end of each month. The amount of each monthly payment may in no event 
exceed an amount equal to a payment at the annual rate of 0.25%, in the case 
of Class A, and 0.85%, in the case of Class C, of the average net assets of 
the respective Class during the month. With respect to Class A, in the case 
of all expenses other than expenses representing the service fee and, with 
respect to Class C, in the case of all expenses other than expenses 
representing a gross sales credit or a residual to account executives, such 
amounts shall be determined at the beginning of each calendar quarter by the 
Directors, including a majority of the Directors who are not "interested 
persons" of the Fund, as defined in the Act. Expenses representing the 
service fee (for Class A) or a gross sales credit or a residual to account 
executives (for Class C) may be reimbursed without prior determination. In 
the event that the Distributor proposes that monies shall be reimbursed for 
other than such expenses, then in making the quarterly determinations of the 
amounts that may be expended by the Fund, the Distributor shall provide, and 
the Directors shall review, a quarterly budget of projected distribution 
expenses to be incurred by the Distributor, DWR, its affiliates or other 
broker-dealers on behalf of the Fund together with a report explaining the 
purposes and anticipated benefits of incurring such expenses. The Directors 
shall determine the particular expenses, and the portion thereof that may be 
borne by the Fund, and in making such determination shall consider the scope 
of the Distributor's commitment to promoting the distribution of the Fund's 
Class A and Class C shares directly or through DWR, its affiliates or other 
broker-dealers. 

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

                                1           
<PAGE>
   1(b). With respect to Class B shares of the Fund, the Fund shall pay to 
the Distributor, as the distributor of securities of which the Fund is the 
issuer, compensation for distribution of its Class B shares at the rate of 
0.75% per annum of the average daily net assets of Class B. Such compensation 
shall be calculated and accrued daily and paid monthly or at such other 
intervals as the Directors shall determine. 

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

   2. With respect to expenses incurred by each Class, the amount set forth 
in paragraph 1 of this Plan shall be paid for services of the Distributor, 
DWR its affiliates and other broker-dealers it may select in connection with 
the distribution of the Fund's shares, including personal services to 
shareholders with respect to their holdings of Fund shares, and may be spend 
by the Distributor, DWR, its affiliates and such broker-dealers on any 
activities or expenses related to the distribution of the Fund's shares or 
services to shareholders, including, but not limited to: compensation to, and 
expenses of, account executives or other employees of the Distributor, DWR, 
its affiliates or other broker-dealers; overhead and other branch office 
distribution-related expenses and telephone expenses of persons who engage in 
or support distribution of shares or who provide personal services to 
shareholders; printing of prospectuses and reports for other than existing 
shareholders; preparation, printing and distribution of sales literature and 
advertising materials and, with respect to Class B, opportunity costs in 
incurring the foregoing expenses (which may be calculated as a carrying 
charge on the excess of the distribution expenses incurred by the 
Distributor, DWR, its affiliates or other broker-dealers over distribution 
revenues received by them, such excess being hereinafter referred to as 
"carryover expenses"). The overhead and other branch office 
distribution-related expenses referred to in this paragraph 2 may include: 
(a) the expenses operating the branch offices of the Distributor or other 
broker-dealers, including DWR, in connection with the sale of the Fund 
shares, including lease costs, the salaries and employee benefits of 
operations and sales support personnel, utility costs, communications costs 
and the costs of stationery and supplies; (b) the costs of client sales 
seminars; (c) travel expenses of mutual fund sales coordinators to promote 
the sale of Fund shares; and (d) other expenses relating to branch promotion 
of Fund sales. Payments may also be made with respect to distribution 
expenses incurred in connection with the distribution of shares, 
includingpersonal services to shareholders with respect to holdings of such 
shares, of an investment company whose assets are acquired by the Fund in a 
tax-free reorganization. It is contemplated that, with respect to Class A 
shares, the entire fee set forth in paragraph 1(a) will be characterized as a 
service fee within the meaning of the National Association of Securities 
Dealers, Inc. guidelines and that, with respect to Class B shares, payments 
at the annual rate of 0.20% will be so characterized and that, with respect 
to Class C shares, payments at the annual rate of 0.25% will be so 
characterized. 

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

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

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

   6. This Plan may be terminated at any time with respect to a Class by vote 
of a majority of the Rule 12b-1 Directors, or by vote of a majority of the 
outstanding voting securities of the Fund. The Plan 

                                2           
<PAGE>
may remain in effect with the respect to a particular Class even if the Plan 
has been terminated in accordance with this paragraph 6 with respect to any 
other Class. In the event of any such termination or in the event of 
nonrenewal, the Fund shall have no obligation to pay expenses which have been 
incurred by the Distributor, DWR, its affiliates or other broker-dealers in 
excess of payments made by the Fund pursuant to this Plan. However, with 
respect to Class B, this shall not preclude consideration by the Directors of 
the manner in which such excess expenses shall be treated. 

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

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

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

   IN WITNESS WHEREOF, the Fund and the Distributor have executed this Plan

                               DEAN WITTER FUNDS
                              MULTIPLE CLASS PLAN
                             PURSUANT TO RULE 18f-3
 
INTRODUCTION
 
    This plan (the "Plan") is adopted pursuant to Rule 18f-3(d) of the
Investment Company Act of 1940, as amended (the "1940 Act"), and will be
effective as of July 28, 1997. The Plan relates to shares of the open-end
investment companies to which Dean Witter InterCapital Inc. acts as investment
manager, that are listed on Schedule A, as may be amended from time to time
(each, a "Fund" and collectively, the "Funds"). The Funds are distributed
pursuant to a system (the "Multiple Class System") in which each class of shares
(each, a "Class" and collectively, the "Classes") of a Fund represents a pro
rata interest in the same portfolio of investments of the Fund and differs only
to the extent outlined below.
 
I.  DISTRIBUTION ARRANGEMENTS
 
    One or more Classes of shares of the Funds are offered for purchase by
investors with the sales load structures described below. In addition, pursuant
to Rule 12b-1 under the 1940 Act, the Funds have each adopted a Plan of
Distribution (the "12b-1 Plan") under which shares of certain Classes are
subject to the service and/or distribution fees ("12b-1 fees") described below.
 
    1.  CLASS A SHARES
 
    Class A shares are offered with a front-end sales load ("FESL"). The
schedule of sales charges applicable to a Fund and the circumstances under which
the sales charges are subject to reduction are set forth in each Fund's current
prospectus. As stated in each Fund's current prospectus, Class A shares may be
purchased at net asset value (without a FESL): (i) in the case of certain large
purchases of such shares; and (ii) by certain limited categories of investors,
in each case, under the circumstances and conditions set forth in each Fund's
current prospectus. Class A shares purchased at net asset value may be subject
to a contingent deferred sales charge ("CDSC") on redemptions made within one
year of purchase. Further information relating to the CDSC, including the manner
in which it is calculated, is set forth in paragraph 6 below. Class A shares are
also subject to payments under each Fund's 12b-1 Plan to reimburse Dean Witter
Distributors Inc., Dean Witter Reynolds Inc. ("DWR"), its affiliates and other
broker-dealers for distribution expenses incurred by them specifically on behalf
of the Class, assessed at an annual rate of up to 0.25% of average daily net
assets. The entire amount of the 12b-1 fee represents a service fee within the
meaning of National Association of Securities Dealers, Inc. ("NASD") guidelines.
 
    2.  CLASS B SHARES
 
    Class B shares are offered without a FESL, but will in most cases be subject
to a six-year declining CDSC which is calculated in the manner set forth in
paragraph 6 below. Class B shares purchased by certain qualified
employer-sponsored benefit plans are subject to a three-year declining CDSC
which is calculated in the manner set forth in paragraph 6 below. The schedule
of CDSC charges applicable to each Fund is set forth in each Fund's current
prospectus. With the exception of certain of the Funds which have a different
formula described below (Dean Witter American Value Fund, Dean Witter Natural
Resource Development Securities Inc., Dean Witter Strategist Fund and Dean
Witter Dividend Growth Securities Inc.)(1), Class B
 
- ------------
 
(1)The payments under the 12b-1 Plan for each of Dean Witter American Value
Fund, Dean Witter Natural Resource Development Securities Inc. and Dean Witter
Dividend Growth Securities Inc. are assessed at the annual rate of 1.0% of the
lesser of: (a) the average daily aggregate gross sales of the Fund's Class B
shares since the inception of the Fund's Plan (not including reinvestment of
dividends or capital gains distributions), less the average daily aggregate net
asset value of the Fund's Class B shares redeemed since the Plan's inception
upon which a contingent deferred sales charge has been imposed or waived, or (b)
the average daily net assets of Class B attributable to shares issued, net of
related shares redeemed, since inception of the Plan. The payments under the
12b-1 Plan for the Dean Witter Strategist Fund are assessed at the annual rate
of: (i) 1% of the lesser of (a) the average daily aggregate gross sales of the
Fund's Class B shares since the effectiveness of the first amendment of the Plan
on November 8, 1989 (not including reinvestment of dividends or capital gains
distributions), less the average daily aggregate net asset value of the Fund's
Class B shares redeemed since the effectiveness of the first amended Plan, upon
which a contingent deferred sales charge has been imposed or waived, or (b) the
average daily net assets of Class B attributable to shares issued, net of
related shares redeemed, since the effectiveness of the first amended Plan; plus
(ii) 0.25% of the average daily net assets of Class B attributable to shares
issued, net of related shares redeemed, prior to effectiveness of the first
amended Plan.
 
                                       1
<PAGE>
shares are also subject to a fee under each Fund's respective 12b-1 Plan,
assessed at the annual rate of up to 1.0% of either: (a) the lesser of (i) the
average daily aggregate gross sales of the Fund's Class B shares since the
inception of the Fund (not including reinvestment of dividends or capital gains
distributions), less the average daily aggregate net asset value of the Fund's
Class B shares redeemed since the Fund's inception upon which a CDSC has been
imposed or waived, or (ii) the average daily net assets of Class B; or (b) the
average daily net assets of Class B. A portion of the 12b-1 fee equal to up to
0.25% of the Fund's average daily net assets is characterized as a service fee
within the meaning of the NASD guidelines and the remaining portion of the 12b-1
fee, if any, is characterized as an asset-based sales charge. Also, Class B
shares have a conversion feature ("Conversion Feature") under which such shares
convert to Class A shares after a certain holding period. Details of the
Conversion Feature are set forth in Section IV below.
 
    3.  CLASS C SHARES
 
    Class C shares are offered without imposition of a FESL, but will in most
cases be subject to a CDSC of 1.0% on redemptions made within one year after
purchase. Further information relating to the CDSC is set forth in paragraph 6
below. In addition, Class C shares, under each Fund's 12b-1 Plan, are subject to
12b-1 payments to reimburse Dean Witter Distributors Inc., DWR, its affiliates
and other broker-dealers for distribution expenses incurred by them specifically
on behalf of the Class, assessed at the annual rate of up to 1.0% of the average
daily net assets of the Class. A portion of the 12b-1 fee equal to up to 0.25%
of the Fund's average daily net assets is characterized as a service fee within
the meaning of NASD guidelines. Unlike Class B shares, Class C shares do not
have the Conversion Feature.
 
    4.  CLASS D SHARES
 
    Class D shares are offered without imposition of a FESL, CDSC or a 12b-1 fee
for purchases of Fund shares by (i) investors meeting an initial minimum
investment requirement and (ii) certain other limited categories of investors,
in each case, as may be approved by the Boards of Directors/Trustees of the
Funds and as disclosed in each Fund's current prospectus.
 
    5.  ADDITIONAL CLASSES OF SHARES
 
    The Boards of Directors/Trustees of the Funds have the authority to create
additional Classes, or change existing Classes, from time to time, in accordance
with Rule 18f-3 under the 1940 Act.
 
    6.  CALCULATION OF THE CDSC
 
    Any applicable CDSC is calculated based upon the lesser of net asset value
of the shares at the time of purchase or at the time of redemption. The CDSC
does not apply to amounts representing an increase in share value due to capital
appreciation and shares acquired through the reinvestment of dividends or
capital gains distributions. The CDSC schedule applicable to a Fund and the
circumstances in which the CDSC is subject to waiver are set forth in each
Fund's prospectus.
 
II.  EXPENSE ALLOCATIONS
 
    Expenses incurred by a Fund are allocated among the various Classes of
shares pro rata based on the net assets of the Fund attributable to each Class,
except that 12b-1 fees relating to a particular Class are allocated directly to
that Class. In addition, other expenses associated with a particular Class
(except advisory or custodial fees), may be allocated directly to that Class,
provided that such expenses are reasonably identified as specifically
attributable to that Class and the direct allocation to that Class is approved
by the Fund's Board of Directors/Trustees.
 
III.  CLASS DESIGNATION
 
    All shares of the Funds held prior to July 28, 1997 (other than the shares
held by certain employee benefit plans established by DWR and its affiliate, SPS
Transaction Services, Inc., shares of Funds offered with a FESL, and shares of
Dean Witter Balanced Growth Fund and Dean Witter Balanced Income Fund) have been
designated Class B shares. Shares held prior to July 28, 1997 by such employee
benefit plans have been designated Class D shares. Shares held prior to July 28,
1997 of Funds offered with a FESL have been designated Class D shares. In
addition, shares of Dean Witter American Value Fund purchased prior to April 30,
1984, shares of Dean Witter Strategist Fund purchased prior to November 8, 1989
and shares of Dean Witter Natural Resource Development Securities Inc. and Dean
Witter Dividend Growth Securities Inc. purchased prior to July 2, 1984 (with
respect to such shares of each Fund, including such proportion of shares
acquired through reinvestment of dividends and capital gains distributions as
the total number of shares acquired prior to each of the preceding dates in this
sentence bears to the total number of shares purchased and owned by the
shareholder of that Fund) have been designated Class D shares. Shares of Dean
Witter Balanced Growth Fund and Dean Witter Balanced Income Fund held prior to
July 28, 1997 have
 
                                       2
<PAGE>
been designated Class C shares except that shares of Dean Witter Balanced Growth
Fund and Dean Witter Balanced Income Fund held prior to July 28, 1997 that were
acquired in exchange for shares of an investment company offered with a CDSC
have been designated Class B shares and those that were acquired in exchange for
shares of an investment company offered with a FESL have been designated Class A
shares.
 
IV.  THE CONVERSION FEATURE
 
    Class B shares held before May 1, 1997 will convert to Class A shares in
May, 2007, except that Class B shares which are purchased before July 28, 1997
by trusts for which Dean Witter Trust Company ("DWTC") or Dean Witter Trust FSB
("DWTFSB") provides discretionary trustee services will convert to Class A
shares on or about August 29, 1997 (the CDSC will not be applicable to such
shares upon the conversion). In all other instances, Class B shares of each Fund
will automatically convert to Class A shares, based on the relative net asset
values of the shares of the two Classes on the conversion date, which will be
approximately ten (10) years after the date of the original purchase.
Conversions will be effected once a month. The 10 year period will be calculated
from the last day of the month in which the shares were purchased or, in the
case of Class B shares acquired through an exchange or a series of exchanges,
from the last day of the month in which the original Class B shares were
purchased, provided that shares originally purchased before May 1, 1997 will
convert to Class A shares in May, 2007. Except as set forth below, the
conversion of shares purchased on or after May 1, 1997 will take place in the
month following the tenth anniversary of the purchase. There will also be
converted at that time such proportion of Class B shares acquired through
automatic reinvestment of dividends owned by the shareholder as the total number
of his or her Class B shares converting at the time bears to the total number of
outstanding Class B shares purchased and owned by the shareholder. In the case
of Class B shares held by a 401(k) plan or other employer-sponsored plan
qualified under Section 401(a) of the Internal Revenue Code (the "Code") and for
which DWTC or DWTFSB serves as Trustee or the 401(k) Support Services Group of
DWR serves as recordkeeper, all Class B shares will convert to Class A shares on
the conversion date of the first shares of a Fund purchased by that plan. In the
case of Class B shares previously exchanged for shares of an "Exchange Fund" (as
such term is defined in the prospectus of each Fund), the period of time the
shares were held in the Exchange Fund (calculated from the last day of the month
in which the Exchange Fund shares were acquired) is excluded from the holding
period for conversion. If those shares are subsequently re-exchanged for Class B
shares of a Fund, the holding period resumes on the last day of the month in
which Class B shares are reacquired.
 
    Effectiveness of the Conversion Feature is subject to the continuing
availability of a ruling of the Internal Revenue Service or an opinion of
counsel to the effect that (i) the conversion of shares does not constitute a
taxable event under the Code; (ii) Class A shares received on conversion will
have a basis equal to the shareholder's basis in the converted Class B shares
immediately prior to the conversion; and (iii) Class A shares received on
conversion will have a holding period that includes the holding period of the
converted Class B shares. The Conversion Feature may be suspended if the Ruling
or opinion is no longer available. In such event, Class B shares would continue
to be subject to Class B fees under the applicable Fund's 12b-1 Plan.
 
V.  EXCHANGE PRIVILEGES
 
    Shares of each Class may be exchanged for shares of the same Class of the
other Funds and for shares of certain other investment companies without the
imposition of an exchange fee as described in the prospectuses and statements of
additional information of the Funds. The exchange privilege of each Fund may be
terminated or revised at any time by the Fund upon such notice as may be
required by applicable regulatory agencies as described in each Fund's
prospectus.
 
VI.  VOTING
 
    Each Class shall have exclusive voting rights on any matter that relates
solely to its 12b-1 Plan, except that Class B shareholders will have the right
to vote on any proposed material increase in Class A's expenses, including
payments under the Class A 12b-1 Plan, if such proposal is submitted separately
to Class A shareholders. If the amount of expenses, including payments under the
Class A 12b-1 Plan, is increased materially without the approval of Class B
shareholders, the Fund will establish a new Class A for Class B shareholders
whose shares automatically convert on the same terms as applied to Class A
before the increase. In addition, each Class shall have separate voting rights
on any matter submitted to shareholders in which the interests of one Class
differ from the interests of any other Class.
