Alternative      Four classes of shares are offered:
Purchase
Arrangements     - Class A shares are offered with a front-end sales charge, starting at 5.25% and reduced
                 for larger purchases. Investments of $1 million or more (and investments by certain other
                 limited categories of investors) are not subject to any sales charge at the time of
                 purchase but a contingent deferred sales charge ("CDSC") of 1.0% may be imposed on
                 redemptions within one year of purchase. The Fund is authorized to reimburse the
                 Distributor for specific expenses incurred in promoting the distribution of the Fund's
                 Class A shares and servicing shareholder accounts pursuant to the Fund's 12b-1 Plan.
                 Reimbursement may in no event exceed an amount equal to payments at an annual rate of
                 0.25% of average daily net assets of the Class (see pages 12, 15 and 21).
                 - Class B shares are offered without a front-end sales charge, but will in most cases be
                 subject to a CDSC (scaled down from 5.0% to 1.0%) if redeemed within six years after
                 purchase. The CDSC will be imposed on any redemption of shares if after such redemption
                 the aggregate current value of a Class B account with the Fund falls below the aggregate
                 amount of the investor's purchase payments made during the six years preceding the
                 redemption. A different CDSC schedule applies to investments by certain qualified plans.
                 Class B shares are also subject to a 12b-1 fee assessed at the annual rate of 1.0% of the
                 lesser of: (a) the average daily net sales of the Fund's Class B shares or (b) the average
                 daily net assets of Class B. All shares of the Fund held prior to July 28, 1997 (other
                 than the shares held by certain employee benefit plans established by Dean Witter Reynolds
                 Inc. and its affiliate, SPS Transaction Services, Inc.) have been designated Class B
                 shares. Shares held by those employee benefit plans prior to July 28, 1997 have been
                 designated Class D shares. Shares held before May 1, 1997 that have been designated Class
                 B shares will convert to Class A shares in May, 2007. In all other instances, Class B
                 shares convert to Class A shares approximately ten years after the date of the original
                 purchase (see pages 12, 18 and 21).
                 - Class C shares are offered without a front-end sales charge, but will in most cases be
                 subject to a CDSC of 1.0% if redeemed within one year after purchase. The Fund is
                 authorized to reimburse the Distributor for specific expenses incurred in promoting the
                 distribution of the Fund's Class C shares and servicing shareholder accounts pursuant to
                 the Fund's 12b-1 Plan. Reimbursement may in no event exceed an amount equal to payments at
                 an annual rate of 1.0% of average daily net assets of the Class (see pages 12, 20 and 21).
                 - 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
                 12, 20 and 21).

- ----------------------------------------------------------------------------------------------------------
Dividends        Dividends from net investment income and distributions from net capital gains, if any, are
and              paid at least once per year. The Fund may, however, determine to retain all or part of any
Capital Gains    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 23 and 27).
- ----------------------------------------------------------------------------------------------------------
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 26).
- ----------------------------------------------------------------------------------------------------------
Special Risk     The net asset value of the Fund's shares will fluctuate with changes in the market value
Considerations   of its portfolio securities. Dividends payable by the Fund will vary in relation to the
                 amount of income earned on portfolio securities. The Fund may engage in transactions
                 involving stock index futures contracts (see pages 8-12).

(1) REDUCED FOR PURCHASES OF $25,000 AND OVER (SEE "PURCHASE OF FUND
    SHARES--INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES").
    
 
   
(2) INVESTMENTS THAT ARE NOT SUBJECT TO ANY SALES CHARGE AT THE TIME OF PURCHASE
    ARE SUBJECT TO A CDSC OF 1.00% THAT WILL BE IMPOSED ON REDEMPTIONS MADE
    WITHIN ONE YEAR AFTER PURCHASE, EXCEPT FOR CERTAIN SPECIFIC CIRCUMSTANCES
    (SEE "PURCHASE OF FUND SHARES--INITIAL SALES CHARGE ALTERNATIVE--CLASS A
    SHARES").
    
 
   
(3) THE CDSC IS SCALED DOWN TO 1.00% DURING THE SIXTH YEAR, REACHING ZERO
    THEREAFTER.
    
 
   
(4) ONLY APPLICABLE TO REDEMPTIONS MADE WITHIN ONE YEAR AFTER PURCHASE (SEE
    "PURCHASE OF FUND SHARES-- LEVEL LOAD ALTERNATIVE--CLASS C SHARES").
    
 
   
(5) THE 12B-1 FEE IS ACCRUED DAILY AND PAYABLE MONTHLY. THE ENTIRE 12B-1 FEE
    PAYABLE BY CLASS A AND A PORTION OF THE 12B-1 FEE PAYABLE BY EACH OF CLASS B
    AND CLASS C EQUAL TO 0.25% OF THE AVERAGE DAILY NET ASSETS OF THE CLASS ARE
    CURRENTLY EACH CHARACTERIZED AS A SERVICE FEE WITHIN THE MEANING OF NATIONAL
    ASSOCIATION OF SECURITIES DEALERS, INC. ("NASD") GUIDELINES AND ARE PAYMENTS
    MADE FOR PERSONAL SERVICE AND/OR MAINTENANCE OF SHAREHOLDER ACCOUNTS. THE
    REMAINDER OF THE 12B-1 FEE, IF ANY, IS AN ASSET-BASED SALES CHARGE, AND IS A
    DISTRIBUTION FEE PAID TO THE DISTRIBUTOR TO COMPENSATE IT FOR THE SERVICES
    PROVIDED AND THE EXPENSES BORNE BY THE DISTRIBUTOR AND OTHERS IN THE
    DISTRIBUTION OF THE FUND'S SHARES (SEE "PURCHASE OF FUND SHARES--PLAN OF
    DISTRIBUTION").
    
 
   
(6) UPON CONVERSION OF CLASS B SHARES TO CLASS A SHARES, SUCH SHARES WILL BE
    SUBJECT TO THE LOWER 12B-1 FEE APPLICABLE TO CLASS A SHARES. NO SALES CHARGE
    IS IMPOSED AT THE TIME OF CONVERSION OF CLASS B SHARES TO CLASS A SHARES.
    CLASS C SHARES DO NOT HAVE A CONVERSION FEATURE AND, THEREFORE, ARE SUBJECT
    TO AN ONGOING 1.00% DISTRIBUTION FEE (SEE "PURCHASE OF FUND
    SHARES--ALTERNATIVE PURCHASE ARRANGEMENTS").
    
 
   
(7) THERE WERE NO OUTSTANDING SHARES OF CLASS A, CLASS C OR CLASS D PRIOR TO THE
    DATE OF THIS PROSPECTUS. ACCORDINGLY, "TOTAL FUND OPERATING EXPENSES," AS
    SHOWN ABOVE WITH RESPECT TO THOSE CLASSES, ARE BASED UPON THE SUM OF 12B-1
    FEES, MANAGEMENT FEES AND ESTIMATED "OTHER EXPENSES."

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
    Dean Witter Value-Added Market Series (the "Fund") is an open-end
diversified management investment company. The Fund is a trust of the type
commonly known as a "Massachusetts business trust" and was organized under the
laws of Massachusetts on May 27, 1987. The Fund currently consists of a single
portfolio, the Equity Portfolio. References herein to the Fund also refer to the
Equity Portfolio if the context so indicates.
 
   
    Dean Witter InterCapital Inc. ("InterCapital" or the "Investment Manager"),
whose address is Two World Trade Center, New York, New York 10048, is the Fund's
Investment Manager. The Investment Manager, which was incorporated in July,
1992, is a wholly-owned subsidiary of Morgan Stanley, Dean Witter, Discover &
Co, a preeminent global financial services firm that maintains leading market
positions in each of its three primary businesses--securities, asset management
and credit services.
    
 
   
    InterCapital and its wholly-owned subsidiary, Dean Witter Services Company
Inc., serve in various investment management, advisory, management and
administrative capacities to 100 investment companies, thirty of which are
listed on the New York Stock Exchange, with combined assets of approximately
$93.1 billion as of June 30, 1997. The Investment Manager also manages
portfolios of pension plans, other institutions and individuals which aggregated
approximately $3.5 billion at such date.
    
 
    The Fund has retained the Investment Manager to provide administrative
services, manage its business affairs and manage the investment of the Fund's
assets, including the placing of orders for the purchase and sale of portfolio
securities. InterCapital has retained Dean Witter Services Company Inc. to
perform the aforementioned administrative services for the Fund.
 
    The Fund's Trustees review the various services provided by or under the
direction of the Investment Manager to ensure that the Fund's general investment
policies and programs are being properly carried out and that administrative
services are being provided to the Fund in a satisfactory manner.
 
   
    As full compensation for the services and facilities furnished to the Fund
and for expenses of the Fund assumed by the Investment Manager, the Fund pays
the Investment Manager monthly compensation calculated daily at an annual rate
of 0.50% of the daily net assets of the Fund up to $500 million, scaled down at
various asset levels to 0.425% on assets over $1 billion. For the fiscal year
ended June 30, 1997, the Fund accrued total compensation to the Investment
Manager amounting to 0.47% of the Fund's average daily net assets and the Fund's
total expenses amounted to 1.45% of the Fund's average daily net assets.
    
 
INVESTMENT OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------
 
    The investment objective of the Equity Portfolio, currently the Fund's
single investment portfolio, is to achieve a high level of total return on its
assets through a combination of capital appreciation and current income. This is
a fundamental policy and cannot be changed without the approval of the
shareholders of the Equity Portfolio. There can be no assurance that the Equity
Portfolio's investment objective will be achieved.
 
    The Fund will seek to attain the Equity Portfolio's investment objective by
investing on an equally-weighted basis in a diversified portfolio of common
stocks of the companies which are included in the Standard & Poor's 500
Composite Stock Price Index (the "S&P Index"). The S&P Index consists of 500
common stocks selected by Standard & Poor's Corporation, most of which are
listed on the New York Stock Exchange. Inclusion of a
 
                                       8
<PAGE>
stock in the S&P Index implies no opinion by Standard & Poor's Corporation
("S&P") as to the quality of the stock as an investment. The S&P Index is
determined, composed and calculated by S&P without regard to the Fund. S&P is
neither a sponsor of, nor in any way affiliated with, the Fund, and S&P makes no
representation or warranty, express or implied, on the advisability of investing
in the Fund or as to the ability of the S&P Index to track general stock market
performance, and S&P disclaims all warranties of merchantability or fitness for
a particular purpose or use with respect to the S&P Index or any data included
therein. S&P has no connection with the Fund other than the licensing to the
Investment Manager of the use of the S&P Index in connection with the Fund.
 
    The Fund invests in the stocks included in the S&P Index on an
equally-weighted basis; that is, to the extent practicable and subject to the
specific investment policies and restrictions described below, an equal portion
of the Fund's assets is invested in each of the 500 securities in the S&P Index.
This differs from the S&P Index and nearly all other major indexes, which
generally are weighted on a market-capitalization basis. For example, the 50
largest capitalization issuers in the S&P Index represent approximately 45% of
the S&P Index. However, in accordance with its investment policies, the Fund
will strive to maintain each stock holding equally, so that, subject to the
specific investment policies and investment restrictions described below,
approximately 0.20 of 1% of the Fund's total invested assets will be invested in
each of the 500 companies included in the S&P Index. The equal-weighting
technique is based on the Investment Manager's statistical analysis that most
portfolio performance is usually generated by only one-quarter to one-third of
the portfolio. Since there is no certainty that any specific company or industry
selection, even within a broad-based index such as the S&P Index, will achieve
superior performance, the Investment Manager believes equal-weighting may
benefit the Fund in seeking to attain its investment objective.
 
    The holdings of the Fund will be adjusted by the Investment Manager not less
than quarterly to reflect changes in the Fund's asset levels and in the relative
values of the common stocks in the Fund's portfolio so that following each
adjustment the value of the Fund's investment in each security will be equal to
the extent practicable. In addition, whenever a company is eliminated from or
added to the S&P Index, the Fund will sell or purchase the stock of such
company, as the case may be, as soon as practicable. Accordingly, securities may
be purchased and sold by the Fund when such purchases and sales would not be
made under traditional investment criteria.
 
    In addition, the Investment Manager may eliminate one or more securities (or
elect not to increase the Fund's position in such securities), notwithstanding
the continued listing of such securities in the S&P Index, in the following
circumstances: (a) the stock is no longer publicly traded, such as in the case
of a leveraged buyout or merger; (b) an unexpected adverse development with
respect to a company, such as bankruptcy or insolvency; (c) in the view of the
Investment Manager, there is a high degree of risk with respect to a company
that bankruptcy or insolvency will occur; or (d) in the view of the Investment
Manager, based on its consideration of the price of a company's securities, the
depth of the market in those securities and the amount of those securities held
or to be held by the Fund, retaining shares of a company or making any
additional purchases would be inadvisable because of liquidity risks. The
Investment Manager will monitor on an ongoing basis all companies falling within
any of the circumstances described in this paragraph, and will return such
company's shares to the Fund's portfolio, or recommence purchases, when and if
those conditions cease to exist.
 
    The investment policies of the Fund are not fundamental and may be changed
by the Trustees without shareholder approval.
 
    STOCK INDEX FUTURES TRANSACTIONS.  The Fund may purchase futures contracts
on stock indexes
 
                                       9
<PAGE>
such as the S&P Index and the New York Stock Exchange Composite Index. Purchase
of a futures contract by the Fund serves as a temporary substitute for the
purchase of individual stocks which may then be purchased in orderly fashion.
The Fund will not enter into futures contracts on stock indexes for speculative
purposes. The Fund may not enter into futures contracts if immediately
thereafter the amount committed to margin exceeds 5% of the value of the Fund's
total assets. There is no overall limitation on the percentage of the Fund's
portfolio securities with respect to which the Fund may purchase or sell futures
contracts. For a discussion of the risks of stock index futures transactions,
see "Risk Considerations" below.
 
    FOREIGN SECURITIES.  The Fund may purchase common stock, including American
Depository Receipts, of foreign corporations represented in the S&P Index (such
securities are listed on the New York Stock Exchange, the American Stock
Exchange or the NASDAQ Market System). For a discussion of the risks of
investing in foreign securities, see "Risk Considerations" below.
 
    TEMPORARY INVESTMENTS  A portion of the Fund's assets, not exceeding 25% of
its total assets, may be invested temporarily in money market instruments under
any one or more of the following circumstances: (a) pending investment of
proceeds of sale of shares of the Fund; (b) pending settlement of purchases of
portfolio securities; or (c) to maintain liquidity for the purposes of meeting
anticipated redemptions. The money market instruments in which the Fund may
invest are certificates of deposit of U.S. domestic banks with assets of $1
billion or more; bankers' acceptances; time deposits; U.S. Government and U.S.
Government agency securities; or commercial paper rated within the two highest
grades by S&P or Moody's Investors Service, Inc., or, if not rated, are of
comparable quality as determined by the Trustees, and which mature within one
year from the date of purchase.
 
    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. For a discussion of the risks of investing in repurchase agreements,
see "Risk Considerations" below.
 
    PRIVATE PLACEMENTS.  The Fund may purchase securities which are sold without
registration under the federal securities laws. Such securities may be held by
the Fund as liquid investments pursuant to procedures adopted by the Fund's
Trustees.
 
RISK CONSIDERATIONS
 
    The net asset value of the Fund's shares will fluctuate with changes in the
market value of its portfolio securities. Dividends payable by the Fund will
vary in relation to the amount of income earned on portfolio securities.
 
    STOCK INDEX FUTURES TRANSACTIONS.  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. This risk is
enhanced for the Fund because no existing index correlates perfectly with both
the composition and equal-weighting policy of the Equity Portfolio. Also, 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. Such distortions are
generally minor and would diminish as the contract approached maturity.
 
    The extent to which the Fund may enter into transactions involving futures
contracts may be limited by the Internal Revenue Code's requirements for
qualification as a regulated investment company
 
                                       10
<PAGE>
and the Fund's intention to qualify as such. See "Dividends, Distributions and
Taxes."
 
    REPURCHASE AGREEMENTS.  While repurchase agreements involve certain risks
not associated with direct investments in debt securities, the Fund follows
procedures designed to minimize those risks. These procedures include effecting
repurchase transactions only with large, well-capitalized and well-established
financial institutions whose financial condition will be continually monitored
by the Investment Manager subject to procedures established by the Board of
Trustees of the Fund. In addition, as described above, the value of the
collateral underlying the repurchase agreement will be at least equal to the
repurchase price, including any accrued interest earned on the repurchase
agreement. In the event of a default or bankruptcy by a selling financial
institution, the Fund will seek to liquidate such collateral. However, the
exercising of the Fund's right to liquidate such collateral could involve
certain costs or delays and, to the extent that proceeds from any sale upon a
default of the obligation to repurchase were less than the repurchase price, the
Fund could suffer a loss. The Fund may not invest in repurchase agreements that
do not mature within seven days if any such investment, together with any other
illiquid assets held by the Fund, amounts to more than 10% of its total assets.
 
    FOREIGN SECURITIES.  Foreign securities investments may be affected by
changes in governmental administration or economic policy (in the United States
and abroad) or changed circumstances in dealings between nations. Foreign
companies may be subject to less governmental regulation than U.S. companies.
Securities of foreign companies may be more volatile than securities of U.S.
companies. As noted above, the Fund's investment in common stock of foreign
corporations represented in the S&P Index may also be in the form of American
Depository Receipts (ADRs). ADRs are receipts typically issued by a United
States bank or trust company evidencing ownership of the underlying securities
and are designed for use in the U.S. securities markets.
 
    For additional risk disclosure, please refer to the "Investment Objective
and Policies" section of the Prospectus and to the "Investment Practices and
Policies" section of the Statement of Additional Information.
 
PORTFOLIO MANAGEMENT
 
   
    The Fund's portfolio is managed by its Investment Manager with a view to
achieving the Fund's investment objective. The Fund's portfolio is managed
within InterCapital's Growth Group, which manages 31 funds and fund portfolios,
with approximately $13.5 billion in assets as of June 30, 1997. Kenton J.
Hinchliffe, Senior Vice President of InterCapital, and Alice S. Weiss, Vice
President of InterCapital, each a member of InterCapital's Growth Group, have
been the primary portfolio managers of the Fund since July, 1993 and July, 1997,
respectively, and have been portfolio managers at InterCapital for over five
years. Since the Fund does not intend generally to engage in short-term trading,
it is anticipated that the Fund's portfolio turnover rate will not exceed 100%.
    
 
   
    Pursuant to an order of the Securities and Exchange Commission, the Fund may
effect principal transactions in certain money market instruments with Dean
Witter Reynolds Inc. ("DWR"), a broker-dealer affiliate 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.
    
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    The investment restrictions listed below are among the restrictions which
have been adopted by the Fund as fundamental policies. Under the Investment
Company Act of 1940, as amended (the "Act"), a fundamental policy may not be
changed without the vote of a majority of the outstanding
 
                                       11
<PAGE>
voting securities of the Fund, as defined in the Act. For purposes of the
following limitations: (i) all percentage limitations apply immediately after a
purchase or initial investment, and (ii) any subsequent change in any applicable
percentage resulting from market fluctuations or other changes in total or net
assets does not require elimination of any security from the portfolio.
 
    The Fund may not:
 
   1. Invest more than 5% of the value of its total assets in the securities of
any one issuer (other than obligations issued or guaranteed by the United States
Government, its agencies or instrumentalities).
 
   2. Purchase more than 10% of all outstanding voting securities or any class
of securities of any one issuer.
 
   3. Invest 25% or more of the value of its total assets in securities of
issuers in any one industry. This restriction does not apply to obligations
issued or guaranteed by the United States Government or its agencies or
instrumentalities.
 
   4. Invest more than 5% of the value of its total assets in securities of
issuers having a record, together with predecessors, of less than three years of
continuous operation. This restriction shall not apply to any obligation issued
or guaranteed by the United States Government, its agencies or
instrumentalities.
 
   
    Notwithstanding any other investment policy or restriction, the Fund may
seek to achieve its investment objective by investing all or substantially all
of its assets in another investment company having substantially the same
investment objective and policies as the Fund.
    
 
PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
   
GENERAL
    
 
   
    The Fund offers each class of its shares for sale to the public on a
continuous basis. Pursuant to a Distribution Agreement between the Fund and Dean
Witter Distributors Inc. (the "Distributor"), an affiliate of the Investment
Manager, shares of the Fund are distributed by the Distributor and offered by
DWR and other dealers who have entered into selected dealer agreements with the
Distributor ("Selected Broker-Dealers"). The principal executive office of the
Distributor is located at Two World Trade Center, New York, New York 10048.
    
 
   
    The Fund offers four classes of shares (each, a "Class"). Class A shares are
sold to investors with an 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.
    
 
                                       12
<PAGE>
   
    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 Value-Added Market Series, Equity
Portfolio, directly to Dean Witter Trust Company (the "Transfer Agent") at P.O.
Box 1040, Jersey City, NJ 07303 or by contacting an account executive of DWR or
other Selected Broker-Dealer. When purchasing shares of the Fund, investors must
specify whether the purchase is for Class A, Class B, Class C or Class D shares.
If no Class is specified, the Transfer Agent will not process the transaction
until the proper Class is identified. The minimum initial purchase in the case
of investments through EasyInvest-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 investments pursuant to Systematic Payroll
Deduction Plans (including Individual Retirement Plans), the Fund, in its
discretion, may accept investments without regard to any minimum amounts which
would otherwise be required if the Fund has reason to believe that additional
investments will increase the investment in all accounts under such Plans to at
least $1,000. Certificates for shares purchased will not be issued unless a
request is made by the shareholder in writing to the Transfer Agent.
    
 
   
    Shares of the Fund are sold through the Distributor on a normal three
business day settlement basis; that is, payment is due on the third business day
(settlement date) after the order is placed with the Distributor. Since DWR and
other Selected Broker-Dealers forward investors' funds on settlement date, they
will benefit from the temporary use of the funds if payment is made prior
thereto. As noted above, orders placed directly with the Transfer Agent must be
accompanied by payment. Investors will be entitled to receive dividends and
capital gains distributions if their order is received by the close of business
on the day prior to the record date for such dividends and distributions. Sales
personnel of a Selected Broker-Dealer are compensated for selling shares of the
Fund by the Distributor or any of its affiliates and/or the Selected Broker-
Dealer. In addition, some sales personnel of the Selected Broker-Dealer will
receive various types of non-cash compensation as special sales incentives,
including trips, educational and/or business seminars and merchandise. The Fund
and the Distributor reserve the right to reject any purchase orders.
    
 
   
ALTERNATIVE PURCHASE ARRANGEMENTS
    
 
   
    The Fund offers several Classes of shares to investors designed to provide
them with the flexibility of selecting an investment best suited to their needs.
The general public is offered three Classes of shares: Class A shares, Class B
shares and Class C shares, which differ principally in terms of sales charges
and rate of expenses to which they are subject. A fourth Class of shares, Class
D shares, is offered only to limited categories of investors (see "No Load
Alternative--Class D Shares" below).
    
 
   
    Each Class A, Class B, Class C or Class D share of the Fund represents an
identical interest in the investment portfolio of the Fund except that Class A,
Class B and Class C shares bear the expenses of the ongoing shareholder service
fees, Class B and Class C shares bear the expenses of the ongoing distribution
fees and Class A, Class B and Class C shares which are redeemed subject to a
CDSC bear the expense of the additional incremental distribution costs resulting
from the CDSC
    
 
                                       13
<PAGE>
   
applicable to shares of those Classes. The ongoing distribution fees that are
imposed on Class A, Class B and Class C shares will be imposed directly against
those Classes and not against all assets of the Fund and, accordingly, such
charges against one Class will not affect the net asset value of any other Class
or have any impact on investors choosing another sales charge option. See "Plan
of Distribution" and "Redemptions and Repurchases."
    
 
   
    Set forth below is a summary of the differences between the Classes and the
factors an investor should consider when selecting a particular Class. This
summary is qualified in its entirety by detailed discussion of each Class that
follows this summary.
    
 
   
    CLASS A SHARES.  Class A shares are sold at net asset value plus an initial
sales charge of up to 5.25%. The initial sales charge is reduced for certain
purchases. Investments of $1 million or more (and investments by certain other
limited categories of investors) are not subject to any sales charges at the
time of purchase but are subject to a CDSC of 1.0% on redemptions made within
one year after purchase, except for certain specific circumstances. Class A
shares are also subject to a 12b-1 fee of up to 0.25% of the average daily net
assets of the Class. See "Initial Sales Charge Alternative--Class A Shares."
    
 
   
    CLASS B SHARES.  Class B shares are offered at net asset value with no
initial sales charge but are subject to a CDSC (scaled down from 5.0% to 1.0%)
if redeemed within six years of purchase. (Class B shares purchased by certain
qualified employer-sponsored benefit plans are subject to a CDSC scaled down
from 2.0% to 1.0% if redeemed within three years after purchase.) This CDSC may
be waived for certain redemptions. Class B shares are also subject to an annual
12b-1 fee of 1.0% of the lesser of: (a) the average daily aggregate gross sales
of the Fund's Class B shares since the inception of the Fund (not including
reinvestments of dividends or capital gains distributions), less the average
daily aggregate net asset value of the Fund's Class B shares redeemed since the
Fund's inception upon which a CDSC has been imposed or waived, or (b) the
average daily net assets of Class B. The Class B shares' distribution fee will
cause that Class to have higher expenses and pay lower dividends than Class A or
Class D shares.
    
 
   
    After approximately ten (10) years, Class B shares will convert
automatically to Class A shares of the Fund, based on the relative net asset
values of the shares of the two Classes on the conversion date. In addition, a
certain portion of Class B shares that have been acquired through the
reinvestment of dividends and distributions will be converted at that time. See
"Contingent Deferred Sales Charge Alternative--Class B Shares."
    
 
   
    CLASS C SHARES.  Class C shares are sold at net asset value with no initial
sales charge but are subject to a CDSC of 1.0% on redemptions made within one
year after purchase. This CDSC may be waived for certain redemptions. They are
subject to an annual 12b-1 fee of up to 1.0% of the average daily net assets of
the Class C shares. The Class C shares' distribution fee may cause that Class to
have higher expenses and pay lower dividends than Class A or Class D shares. See
"Level Load Alternative--Class C Shares."
    
 
   
    CLASS D SHARES.  Class D shares are available only to limited categories of
investors (see "No Load Alternative--Class D Shares" below). Class D shares are
sold at net asset value with no initial sales charge or CDSC. They are not
subject to any 12b-1 fees. See "No Load Alternative--Class D Shares."
    
 
   
    SELECTING A PARTICULAR CLASS.  In deciding which Class of Fund shares to
purchase, investors should consider the following factors, as well as any other
relevant facts and circumstances:
    
 
   
    The decision as to which Class of shares is more beneficial to an investor
depends on the amount and intended length of his or her investment. Investors
who prefer an initial sales charge alternative may elect to purchase Class A
shares. Investors qualifying for significantly reduced or, in the case of
purchases of $1 million or more, no
    
 
                                       14
<PAGE>
   
initial sales charges may find Class A shares particularly attractive because
similar sales charge reductions are not available with respect to Class B or
Class C shares. Moreover, Class A shares are subject to lower ongoing expenses
than are Class B or Class C shares over the term of the investment. As an
alternative, Class B and Class C shares are sold without any initial sales
charge so the entire purchase price is immediately invested in the Fund. Any
investment return on these additional investment amounts may partially or wholly
offset the higher annual expenses of these Classes. Because the Fund's future
return cannot be predicted, however, there can be no assurance that this would
be the case.
    
 
   
    Finally, investors should consider the effect of the CDSC period and any
conversion rights of the Classes in the context of their own investment time
frame. For example, although Class C shares are subject to a significantly lower
CDSC upon redemptions, they do not, unlike Class B shares, convert into Class A
shares after approximately ten years, and, therefore, are subject to an ongoing
12b-1 fee of 1.0% (rather than the 0.25% fee applicable to Class A shares) for
an indefinite period of time. Thus, Class B shares may be more attractive than
Class C shares to investors with longer term investment outlooks. Other
investors, however, may elect to purchase Class C shares if, for example, they
determine that they do not wish to be subject to a front-end sales charge and
they are uncertain as to the length of time they intend to hold their shares.
    
 
   
    For the purpose of meeting the $5 million minimum investment amount for
Class D shares, holdings of Class A shares in all Dean Witter Multi-Class Funds,
shares of FSC Funds and shares of Dean Witter Funds for which such shares have
been exchanged will be included together with the current investment amount.
    
 
   
    Sales personnel may receive different compensation for selling each Class of
shares. Investors should understand that the purpose of a CDSC is the same as
that of the initial sales charge in that the sales charges applicable to each
Class provide for the financing of the distribution of shares of that Class.
    
 
   
    Set forth below is a chart comparing the sales charge, 12b-1 fees and
conversion options applicable to each Class of shares:

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
    
 
                                       15
<PAGE>
   
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
    
 
                                       16
<PAGE>
   
Funds previously purchased at a price including a front-end sales charge
(including shares of the Fund and other Dean Witter Funds acquired in exchange
for those shares, and including in each case shares acquired through
reinvestment of dividends and distributions), which are held at the time of such
transaction, amounts to $25,000 or more. If such investor has a cumulative net
asset value of shares of FSC Funds and Class A and Class D shares equal to at
least $5 million, such investor is eligible to purchase Class D shares subject
to the $1,000 minimum initial investment requirement of that Class of the Fund.
See "No Load Alternative-- Class D Shares" below.
    
 
   
    The Distributor must be notified by DWR or a Selected Broker-Dealer or the
shareholder at the time a purchase order is placed that the purchase qualifies
for the reduced charge under the Right of Accumulation. Similar notification
must be made in writing by the dealer or shareholder when such an order is
placed by mail. The reduced sales charge will not be granted if: (a) such
notification is not furnished at the time of the order; or (b) a review of the
records of the Selected Broker-Dealer or the Transfer Agent fails to confirm the
investor's represented holdings.
    
 
   
    LETTER OF INTENT.  The foregoing schedule of reduced sales charges will also
be available to investors who enter into a written Letter of Intent providing
for the purchase, within a thirteen-month period, of Class A shares of the Fund
from DWR or other Selected Broker-Dealers. The cost of Class A shares of the
Fund or shares of other Dean Witter Funds which were previously purchased at a
price including a front-end sales charge during the 90-day period prior to the
date of receipt by the Distributor of the Letter of Intent, or of Class A shares
of the Fund or shares of other Dean Witter Funds acquired in exchange for shares
of such funds purchased during such period at a price including a front-end
sales charge, which are still owned by the shareholder, may also be included in
determining the applicable reduction.
    
 
   
    ADDITIONAL NET ASSET VALUE PURCHASE OPTIONS. In addition to investments of
$1 million or more, Class A shares also may be purchased at net asset value by

   (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

CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE-- CLASS B SHARES
    
 
   
    Class B shares are sold at net asset value next determined without an
initial sales charge so that the full amount of an investor's purchase payment
may be immediately invested in the Fund. A CDSC, however, will be imposed on
most Class B shares redeemed within six years after purchase. The CDSC will be
imposed on any redemption of shares if after such redemption the aggregate
current value of a Class B account with the Fund falls below the aggregate
amount of the investor's purchase payments for Class B shares made during the
six years (or, in the case of shares held by certain employer-sponsored benefit
plans, three years) preceding the redemption. In addition, Class B shares are
subject to an annual 12b-1 fee of 1.0% of the lesser of: (a) the average daily
aggregate gross sales of the Fund's Class B shares since the inception of the
Fund (not including reinvestments of dividends or capital gains distributions),
less the average daily aggregate net asset value of the Fund's Class B shares
redeemed since the Fund's inception upon which a CDSC has been imposed or
waived, or (b) the average daily net assets of Class B.
    
 
   
    Except as noted below, Class B shares of the Fund which are held for six
years or more after purchase (calculated from the last day of the month in which
the shares were purchased) will not be subject to any CDSC upon redemption.
Shares redeemed earlier than six years after purchase may, however, be subject
to a CDSC which will be a percentage of the dollar amount of shares redeemed and
will be assessed on an amount equal to the lesser of the current market value or
the cost of the shares being redeemed. The size of this percentage will depend
upon how long the shares have been held, as set forth in the following table:

Code for which DWTC or DWTFSB serves as Trustee or the 401(k) Support Services
Group of DWR serves as recordkeeper and whose accounts are opened on or after
July 28, 1997, shares held for three years or more after purchase (calculated as
described in the paragraph above) will not be subject to any CDSC upon
redemption. However, shares redeemed earlier than three years after purchase may
be subject to a CDSC (calculated as described in the paragraph above), the
percentage of which will depend on how long the shares have been held, as set

    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-spon-
    
 
                                       18

sored benefit plans, three years) preceding the redemption; (ii) the current net
asset value of shares purchased more than six years (or, in the case of shares
held by certain employer-sponsored benefit plans, three years) prior to the
redemption; and (iii) the current net asset value of shares purchased through
reinvestment of dividends or distributions and/or shares acquired in exchange
for shares of FSC Funds or of other Dean Witter Funds acquired in exchange for
such shares. Moreover, in determining whether a CDSC is applicable it will be
assumed that amounts described in (i), (ii) and (iii) above (in that order) are
redeemed first.
    
 
   
    In addition, the CDSC, if otherwise applicable, will be waived in the case
of:
    
 
   
   (1) redemptions of shares held at the time a shareholder dies or becomes
disabled, only if the shares are:  (a) registered either in the name of an
individual shareholder (not a trust), or in the names of such shareholder and
his or her spouse as joint tenants with right of survivorship; or  (b) held in a
qualified corporate or self-employed retirement plan, Individual Retirement
Account ("IRA") or Custodial Account under Section 403(b)(7) of the Internal
Revenue Code ("403(b) Custodial Account"), provided in either case that the
redemption is requested within one year of the death or initial determination of
disability;
    
 
   
   (2) redemptions in connection with the following retirement plan
distributions:  (a) lump-sum or other distributions from a qualified corporate
or self-employed retirement plan following retirement (or, in the case of a "key
employee" of a "top heavy" plan, following attainment of age 59 1/2); (b)
distributions from an IRA or 403(b) Custodial
Account following attainment of age 59 1/2; or  (c) a tax-free return of an
excess contribution to an IRA; and
    
 
   
   (3) all redemptions of shares held for the benefit of a participant in a
401(k) plan or other employer-sponsored plan qualified under Section 401(a) of
the Internal Revenue Code which offers investment companies managed by the
Investment Manager or its subsidiary, Dean Witter Services Company Inc., as
self-directed investment alternatives and for which DWTC or DWTFSB serves as
Trustee or the 401(k) Support Services Group of DWR serves as recordkeeper
("Eligible Plan"), provided that either:  (a) the plan continues to be an
Eligible Plan after the redemption; or  (b) the redemption is in connection with
the complete termination of the plan involving the distribution of all plan
assets to participants.
    
 
   
    With reference to (1) above, for the purpose of determining disability, the
Distributor utilizes the definition of disability contained in Section 72(m)(7)
of the Internal Revenue Code, which relates to the inability to engage in
gainful employment. With reference to (2) above, the term "distribution" does
not encompass a direct transfer of IRA, 403(b) Custodial Account or retirement
plan assets to a successor custodian or trustee. All waivers will be granted
only following receipt by the Distributor of confirmation of the shareholder's
entitlement.
    
 
   
    CONVERSION TO CLASS A SHARES.  All shares of the Fund held prior to July 28,
1997 (other than shares held by certain employee benefit plans established by
DWR and its affiliate, SPS Transaction Services, Inc.) have been designated
Class B shares. Shares held before May 1, 1997 that have been designated Class B
shares will convert to Class A shares in May, 2007. In all other instances Class
B shares will convert automatically to Class A shares, based on the relative net
asset values of the shares of the two Classes on the conversion date, which will
be approximately ten (10) years after the date of the original purchase. The ten
year period is calculated from the last day of the month in which the shares
were purchased or, in the case of Class B shares acquired through an exchange or
a series of exchanges, from the last day of the month in which the original
Class B shares were purchased, provided that shares originally purchased before
May 1, 1997 will convert to Class A shares in May, 2007. The conversion of
shares purchased on or after May 1, 1997 will take place in the month following
the tenth anniversary of the purchase. There will
    
 
                                       19
<PAGE>
   
also be converted at that time such proportion of Class B shares acquired
through automatic reinvestment of dividends and distributions owned by the
shareholder as the total number of his or her Class B shares converting at the
time bears to the total number of outstanding Class B shares purchased and owned
by the shareholder. In the case of Class B shares held by a 401(k) plan or other
employer-sponsored plan qualified under Section 401(a) of the Internal Revenue
Code and for which DWTC or DWTFSB serves as Trustee or the 401(k) Support
Services Group of DWR serves as recordkeeper, the plan is treated as a single
investor and all Class B shares will convert to Class A shares on the conversion
date of the first shares of a Dean Witter Multi-Class Fund purchased by that
plan. In the case of Class B shares previously exchanged for shares of an
"Exchange Fund" (see "Shareholder Services--Exchange Privilege"), the period of
time the shares were held in the Exchange Fund (calculated from the last day of
the month in which the Exchange Fund shares were acquired) is excluded from the
holding period for conversion. If those shares are subsequently re-exchanged for
Class B shares of a Dean Witter Multi-Class Fund, the holding period resumes on
the last day of the month in which Class B shares are reacquired.
    
 
   
    If a shareholder has received share certificates for Class B shares, such
certificates must be delivered to the Transfer Agent at least one week prior to
the date for conversion. Class B shares evidenced by share certificates that are
not received by the Transfer Agent at least one week prior to any conversion
date will be converted into Class A shares on the next scheduled conversion date
after such certificates are received.
    
 
   
    Effectiveness of the conversion feature is subject to the continuing
availability of a ruling of the Internal Revenue Service or an opinion of
counsel that (i) the conversion of shares does not constitute a taxable event
under the Internal Revenue Code, (ii) Class A shares received on conversion will
have a basis equal to the shareholder's basis in the converted Class B shares
immediately prior to the conversion, and (iii) Class A shares received on
conversion will have a holding period that includes the holding period of the
converted Class B shares. The conversion feature may be suspended if the ruling
or opinion is no longer available. In such event, Class B shares would continue
to be subject to Class B 12b-1 fees.
    
 
   
    Class B shares purchased before July 28, 1997 by trusts for which DWTC or
DWTFSB provides discretionary trustee services will convert to Class A shares on
or about August 29, 1997. The CDSC will not be applicable to such shares.
    
 
   
LEVEL LOAD ALTERNATIVE--CLASS C SHARES
    
 
   
    Class C shares are sold at net asset value next determined without an
initial sales charge but are subject to a CDSC of 1.0% on most redemptions made
within one year after purchase (calculated from the last day of the month in
which the shares were purchased). The CDSC will be assessed on an amount equal
to the lesser of the current market value or the cost of the shares being
redeemed. The CDSC will not be imposed in the circumstances set forth above in
the section "Contingent Deferred Sales Charge Alternative--Class B Shares--CDSC
Waivers," except that the references to six years in the first paragraph of that
section shall mean one year in the case of Class C shares. Class C shares are
subject to an annual 12b-1 fee of up to 1.0% of the average daily net assets of
the Class. Unlike Class B shares, Class C shares have no conversion feature and,
accordingly, an investor that purchases Class C shares will be subject to 12b-1
fees applicable to Class C shares for an indefinite period subject to annual
approval by the Fund's Board of Trustees and regulatory limitations.
    
 
   
NO LOAD ALTERNATIVE--CLASS D SHARES
    
 
   
    Class D shares are offered without any sales charge on purchase or
redemption and without any 12b-1 fee. Class D shares are offered only to
investors meeting an initial investment minimum of $5 million and the following
categories of investors: (i) investors participating in the InterCapital mutual
fund asset allocation program pursuant to which such persons pay an asset based
fee; (ii) persons participating in a fee-based program approved by the
Distributor, pursuant
    
 
                                       20
<PAGE>
   
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. Shares of the Fund held by the employee
benefit plans referred to in clause (iii) above prior to July 28, 1997 have been
designated Class D shares. Investors who require a $5 million minimum initial
investment to qualify to purchase Class D shares may satisfy that requirement by
investing that amount in a single transaction in Class D shares of the Fund and
other Dean Witter Multi-Class Funds, subject to the $1,000 minimum initial
investment required for that Class of the Fund. In addition, for the purpose of
meeting the $5 million minimum investment amount, holdings of Class A shares in
all Dean Witter Multi-Class Funds, shares of FSC Funds and shares of Dean Witter
Funds for which such shares have been exchanged will be included together with
the current investment amount. If a shareholder redeems Class A shares and
purchases Class D shares, such redemption may be a taxable event.
    
 
   
PLAN OF DISTRIBUTION
    
 
   
    The Fund has adopted a Plan of Distribution pursuant to Rule 12b-1 under the
Act with respect to the distribution of Class A, Class B and Class C shares of
the Fund. In the case of Class A and Class C shares, the Plan provides that the
Fund will reimburse the Distributor and others for the expenses of certain
activities and services incurred by them specifically on behalf of those shares.
Reimbursements for these expenses will be made in monthly payments by the Fund
to the Distributor, which will in no event exceed amounts equal to payments at
the annual rates of 0.25% and 1.0% of the average daily net assets of Class A
and Class C, respectively. In the case of Class B shares, the Plan provides that
the Fund will pay the Distributor a fee, which is accrued daily and paid
monthly, at the annual rate of 1.0% of the lesser of: (a) the average daily
aggregate gross sales of the Fund's Class B shares since the inception of the
Fund (not including reinvestments of dividends or capital gains distributions),
less the average daily aggregate net asset value of the Fund's Class B shares
redeemed since the Fund's inception upon which a CDSC has been imposed or
waived, or (b) the average daily net assets of Class B. The fee is treated by
the Fund as an expense in the year it is accrued. In the case of Class A shares,
the entire amount of the fee currently represents a service fee within the
meaning of the NASD guidelines. In the case of Class B and Class C shares, a
portion of the fee payable pursuant to the Plan, equal to 0.25% of the average
daily net assets of each of these Classes, is currently characterized as a
service fee. A service fee is a payment made for personal service and/or the
maintenance of shareholder accounts.
    
 
   
    Additional amounts paid under the Plan in the case of Class B and Class C
shares are paid to the Distributor for services provided and the expenses borne
by the Distributor and others in the distribution of the shares of those
Classes, including the payment of commissions for sales of the shares of those
Classes and incentive compensation to and expenses of DWR's account executives
and others who engage in or support distribution of shares or who service
shareholder accounts, including overhead and telephone expenses; printing and
distribution of prospectuses and reports used in connection with the offering of
the Fund's shares to other than current shareholders; and preparation, printing
and distribution of sales literature and advertising materials. In addition, the
Distributor may utilize fees paid pursuant to the Plan in the case of Class B
shares to compensate DWR and other Selected Broker-Dealers for their opportunity
costs in advancing such amounts, which compensation would be in the form of a
carrying charge on any unreimbursed expenses.
    
 
   
    For the fiscal year ended June 30, 1997, the Fund accrued payments under the
Plan amounting to $9,411,862, which amount is equal to 0.84% of
    
 
                                       21
<PAGE>
   
the Fund's average daily net assets for the fiscal year. These payments accrued
under the Plan were calculated pursuant to clause (a) of the compensation
formula under the Plan. All shares held prior to July 28, 1997 (other than
shares held by certain employee benefit plans established by DWR and its
affiliate, SPS Transaction Services, Inc.) have been designated Class B shares.
    
 
   
    In the case of Class B shares, at any given time, the expenses in
distributing Class B shares of the Fund may be in excess of the total of (i) the
payments made by the Fund pursuant to the Plan, and (ii) the proceeds of CDSCs
paid by investors upon the redemption of Class B shares. For example, if $1
million in expenses in distributing Class B shares of the Fund had been incurred
and $750,000 had been received as described in (i) and (ii) above, the excess
expense would amount to $250,000. The Distributor has advised the Fund that such
excess amounts, including the carrying charge described above, totalled
$61,114,557 at June 30, 1997, which was equal to 4.46% of the Fund's net assets
on such date. Of this amount, $28,379,160 represents excess distribution
expenses of Dean Witter Equity Income Trust, the net assets of which were
combined with those of the Fund on April 18, 1994 pursuant to an Agreement and
Plan of Reorganization. Because there is no requirement under the Plan that the
Distributor be reimbursed for all distribution expenses or any requirement that
the Plan be continued from year to year, such excess amount does not constitute
a liability of the Fund. Although there is no legal obligation for the Fund to
pay expenses incurred in excess of payments made to the Distributor under the
Plan and the proceeds of CDSCs paid by investors upon redemption of shares, if
for any reason the Plan is terminated, the Trustees will consider at that time
the manner in which to treat such expenses. Any cumulative expenses incurred,
but not yet recovered through distribution fees or CDSCs, may or may not be
recovered through future distribution fees or CDSCs.
    
 
   
    In the case of Class A and Class C shares, expenses incurred pursuant to the
Plan in any calendar year in excess of 0.25% or 1.0% of the average daily net
assets of Class A or Class C, respectively, will not be reimbursed by the Fund
through payments in any subsequent year, except that expenses representing a
gross sales commission credited to account executives at the time of sale may be
reimbursed in the subsequent calendar year. No interest or other financing
charges will be incurred on any Class A or Class C distribution expenses
incurred by the Distributor under the Plan or on any unreimbursed expenses due
to the Distributor pursuant to the Plan.
    
 
DETERMINATION OF NET ASSET VALUE
 
   
    The net asset value per share is determined once daily at 4:00 p.m., New
York time (or, on days when the New York Stock Exchange closes prior to 4:00
p.m., at such earlier time), on each day that the New York Stock Exchange is
open by taking the net assets of the Fund, dividing by the number of shares
outstanding and adjusting to the nearest cent. The assets belonging to the Class
A, Class B, Class C and Class D shares will be invested together in a single
portfolio. The net asset value of each Class, however, will be determined
separately by subtracting each Class's accrued expenses and liabilities. The net
asset value per share will not be determined on Good Friday and on such other
federal and non-federal holidays as are observed by the New York Stock Exchange.
    
 
   
    In the calculation of the Fund's net asset value: (1) an equity portfolio
security listed or traded on the New York or American Stock Exchange is valued
at its latest sale price on that exchange prior to the time assets are valued;
if there were no sales that day, the security is valued at the latest bid price
(in cases where a security is traded on more than one exchange, the security is
valued on the exchange designated as the primary market pursuant to procedures
adopted by the Trustees); and (2) all other portfolio securities for which
over-the-counter market quotations are readily available are valued at the
latest bid price. When market quotations are not readily available, including
circumstances under which it is determined by the Investment Manager that sale
and bid prices are not reflective of a security's market value, portfolio
securities are valued at
    
 
                                       22
<PAGE>
their fair value as determined in good faith under procedures established by and
under the general supervision of the Fund's Trustees.
 
    Short-term debt securities with remaining maturities of sixty days or less
at the time of purchase are valued at amortized cost, unless the Trustees
determine such does not reflect the securities' market value, in which case
these securities will be valued at their fair value as determined by the
Trustees.
 
    Certain debt securities in the Fund's portfolio may be valued by an outside
pricing service approved by the Fund's Trustees. The pricing service may utilize
a matrix system incorporating security quality, maturity and coupon as the
evaluation model parameters, and/or research evaluations by its staff, including
review of broker-dealer market price quotations, in determining what it believes
is the fair valuation of the portfolio securities valued by such pricing
service.
 
SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 
   
    AUTOMATIC INVESTMENT OF DIVIDENDS AND DISTRIBUTIONS.  All income dividends
and capital gains distributions are automatically paid in full and fractional
shares of the applicable Class of the Fund (or, if specified by the shareholder,
in shares of any other open-end Dean Witter Fund), unless the shareholder
requests that they be paid in cash. Shares so acquired are acquired at net asset
value and are not subject to the imposition of a front-end sales charge or a
CDSC (see "Redemptions and Repurchases").
    
   
    INVESTMENT OF DIVIDENDS OR DISTRIBUTIONS RECEIVED IN CASH.  Any shareholder
who receives a cash payment representing a dividend or capital gains
distribution may invest such dividend or distribution in shares of the
applicable Class at the net asset value per share next determined after receipt
by the Transfer Agent, by returning the check or the proceeds to the Transfer
Agent within thirty days after the payment date. Shares so acquired are acquired
at net asset value and are not subject to the imposition of a front-end sales
charge or a CDSC (see "Redemptions and Repurchases").
    
 
   
    EASYINVEST-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 systematic withdrawal plan (the "Withdrawal
Plan") is available for shareholders who own or purchase shares of the Fund
having a minimum value of $10,000 based upon the then current net asset value.
The Withdrawal Plan provides for monthly or quarterly (March, June, September
and December) checks in any dollar amount, not less than $25, or in any whole
percentage of the account balance, on an annualized basis. Any applicable CDSC
will be imposed on shares redeemed under the Withdrawal Plan (see "Purchase of
Fund Shares"). Therefore, any shareholder participating in the Withdrawal Plan
will have sufficient shares redeemed from his or her account so that the
proceeds (net of any applicable CDSC) to the shareholder will be the designated
monthly or quarterly amount. Withdrawal plan payments should not be considered
as dividends, yields or income. If periodic withdrawal plan payments
continuously exceed net investment income and net capital gains, the
shareholder's original investment will be correspondingly reduced and ultimately
exhausted. Each withdrawal constitutes a redemption of shares and any gain or
loss realized must be recognized for federal income tax purposes.
    
 
    Shareholders should contact their DWR or other Selected Broker-Dealer
account executive or the Transfer Agent for further information about any of the
above services.
 
    TAX SHELTERED RETIREMENT PLANS.  Retirement plans are available for use by
corporations, the self-
 
                                       23
<PAGE>
employed, Individual Retirement Accounts and Custodial Accounts under Section
403(b)(7) of the Internal Revenue Code. Adoption of such plans should be on
advice of legal counsel or tax adviser.
 
    For further information regarding plan administration, custodial fees and
other details, investors should contact their DWR or other Selected Broker-
Dealer account executive or the Transfer Agent.
 
EXCHANGE PRIVILEGE
 
   
    Shares of each Class may be exchanged for shares of the same Class of any
other Dean Witter Multi-Class Fund without the imposition of any exchange fee.
Shares may also be exchanged for shares of the following funds: Dean Witter
Short-Term U.S. Treasury Trust, Dean Witter Limited Term Municipal Trust, Dean
Witter Short-Term Bond Fund, Dean Witter Intermediate Term U.S. Treasury Trust
and five Dean Witter funds which are money market funds (the "Exchange Funds").
Class A shares may also be exchanged for shares of Dean Witter Multi-State
Municipal Series Trust and Dean Witter Hawaii Municipal Trust, which are Dean
Witter Funds sold with a front-end sales charge ("FSC Funds"). Class B shares
may also be exchanged for shares of Dean Witter Global Short-Term Income Fund
Inc., Dean Witter High Income Securities and Dean Witter National Municipal
Trust, which are Dean Witter Funds offered with a CDSC ("CDSC Funds"). Exchanges
may be made after the shares of the fund acquired by purchase (not by exchange
or dividend reinvestment) have been held for thirty days. There is no waiting
period for exchanges of shares acquired by exchange or dividend reinvestment.
    
 
   
    An exchange to another Dean Witter Multi-Class Fund, any FSC Fund, any CDSC
Fund or any Exchange Fund that is not a money market fund is on the basis of the
next calculated net asset value per share of each fund after the exchange order
is received. When exchanging into a money market fund from the Fund, shares of
the Fund are redeemed out of the Fund at their next calculated net asset value
and the proceeds of the redemption are used to purchase shares of the money
market fund at their net asset value determined the following business day.
Subsequent exchanges between any of the money market funds and any of the Dean
Witter Multi-Class Funds, FSC Funds or CDSC Funds or any Exchange Fund that is
not a money market fund can be effected on the same basis.
    
 
   
    No CDSC is imposed at the time of any exchange of shares, although any
applicable CDSC will be imposed upon ultimate redemption. During the period of
time the shareholder remains in an Exchange Fund (calculated from the last day
of the month in which the Exchange Fund shares were acquired), the holding
period (for the purpose of determining the rate of the CDSC) is frozen. If those
shares are subsequently re-exchanged for shares of a Dean Witter Multi-Class
Fund or shares of a CDSC Fund, the holding period previously frozen when the
first exchange was made resumes on the last day of the month in which shares of
a Dean Witter Multi-Class Fund or shares of a CDSC Fund are reacquired. Thus,
the CDSC is based upon the time (calculated as described above) the shareholder
was invested in shares of a Dean Witter Multi-Class Fund or in shares of a CDSC
Fund (see "Purchase of Fund Shares"). In the case of exchanges of Class A shares
which are subject to a CDSC, the holding period also includes the time
(calculated as described above) the shareholder was invested in shares of a FSC
Fund. However, in the case of shares 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, if any, 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 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
    
 
                                       24
<PAGE>
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
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 account executive (no Exchange Privilege
Authorization Form is required). Other shareholders (and those shareholders who
are clients of DWR or another Selected Broker-Dealer but who wish to make
exchanges directly by writing or telephoning the Transfer Agent) must complete
and forward to the Transfer Agent an Exchange Privilege Authorization Form,
copies of which may be obtained from the Transfer Agent, to initiate an
exchange. If the Authorization Form is used, exchanges may be made in writing or
by contacting the Transfer Agent at (800) 869-NEWS (toll-free).
 
    The Fund will employ reasonable procedures to confirm that exchange
instructions communicated over the telephone are genuine. Such procedures may
include requiring various forms of personal identification such as name, mailing
address, social security or other tax identification number and DWR or other
Selected Broker-Dealer account number (if any). Telephone instructions may also
be recorded. If such procedures are not employed, the Fund may be liable for any
losses due to unauthorized or fraudulent instructions.
 
    Telephone exchange instructions will be accepted if received by the Transfer
agent between 9:00 a.m. and 4:00 p.m., New York time, on any day the New York
Stock Exchange is open. Any shareholder wishing to make an exchange who has
previously filed an Exchange Privilege Authorization Form and who is unable to
reach the Fund by telephone should contact his or her DWR or other Selected
Broker-Dealer account executive, if appropriate, or make a written exchange
request. Shareholders are advised that during periods of drastic economic or
market changes, it is possible that the telephone exchange procedures may be
difficult to
 
                                       25
<PAGE>
implement, although this has not been the case with the Dean Witter Funds in the
past.
 
    Shareholders should contact their DWR or other Selected Broker-Dealer
account executive or the Transfer Agent for further information about the
Exchange Privilege.
 
REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 
   
    REDEMPTION.  Shares of each Class of the Fund can be redeemed for cash at
any time at the net asset value per share next determined less the amount of any
applicable CDSC in the case of Class A, Class B or Class C shares (see "Purchase
of Fund Shares"). If shares are held in a shareholder's account without a share
certificate, a written request for redemption to the Fund's Transfer Agent at
P.O. Box 983, Jersey City, NJ 07303 is required. If certificates are held by the
shareholder, the shares may be redeemed by surrendering the certificates with a
written request for redemption along with any additional documentation required
by the Transfer Agent.
    
 
   
    REPURCHASE.  DWR and other Selected Broker-Dealers are authorized to
repurchase shares represented by a share certificate which is delivered to any
of their offices. Shares held in a shareholder's account without a share
certificate may also be repurchased by DWR and other Selected Broker-Dealers
upon the telephonic request of the shareholder. The repurchase price is the net
asset value next computed (see "Purchase of Fund Shares") after such repurchase
order is received by DWR or other Selected Broker-Dealer, reduced by any
applicable CDSC.
    
 
   
    The CDSC, if any, will be the only fee imposed by the Fund or the
Distributor. The offer by DWR and other Selected Broker-Dealers to repurchase
shares may be suspended without notice by them at any time. In that event,
shareholders may redeem their shares through the Fund's Transfer Agent as set
forth above under "Redemption."
    
 
   
    PAYMENT FOR SHARES REDEEMED OR REPURCHASED.  Payment for shares presented
for repurchase or redemption will be made by check within seven days after
receipt by the Transfer Agent of the certificate and/or written request in good
order. Such payment may be postponed or the right of redemption suspended under
unusual circumstances, e.g., when normal trading is not taking place on the New
York Stock Exchange. If the shares to be redeemed have recently been purchased
by check, payment of the redemption proceeds may be delayed for the minimum time
needed to verify that the check used for investment has been honored (not more
than fifteen days from the time of receipt of the check by the Transfer Agent).
Shareholders maintaining margin accounts with DWR or another Selected
Broker-Dealer are referred to their account executive regarding restrictions on
redemption of shares of the Fund pledged in the margin account.
    
 
   
    REINSTATEMENT PRIVILEGE.  A shareholder who has had his or her shares
redeemed or repurchased and has not previously exercised this reinstatement
privilege may, within 35 days after the date of the redemption or repurchase,
reinstate any portion or all of the proceeds of such redemption or repurchase in
shares of the Fund in the same Class from which such shares were redeemed or
repurchased, at their net asset value next determined after a reinstatement
request, together with the proceeds, is received by the Transfer Agent and
receive a pro rata credit for any CDSC paid in connection with such redemption
or repurchase.
    
 
    INVOLUNTARY REDEMPTION.  The Fund reserves the right, on sixty days' notice,
to redeem, at their net asset value, the shares of any shareholder (other than
shares held in an Individual Retirement Account or custodial account under
Section 403(b)(7) of the Internal Revenue Code) whose shares due to redemptions
by the shareholder have a value of less than $100 or such lesser amount as may
be fixed by the Trustees or, in the case of an account opened through
EasyInvest-SM-, if after twelve
 
                                       26
<PAGE>
   
months the shareholder has invested less than $1,000 in the account. However,
before the Fund redeems such shares and sends the proceeds to the shareholder it
will notify the shareholder that the value of the shares is less than the
applicable amount and allow the shareholder sixty days to make an additional
investment in an amount which will increase the value of the account to at least
the applicable amount before the redemption is processed. No CDSC will be
imposed on any involuntary redemption.
    
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
   
    DIVIDENDS AND DISTRIBUTIONS.  The Fund declares dividends separately for
each Class of shares and intends to distribute all of its net investment income
and net realized short-term and long-term capital gains, if any, at least once
per year. The Fund may, however, determine either to distribute or to retain all
or part of any net long-term capital gains in any year for reinvestment.
    
 
   
    All dividends and any capital gains distributions will be paid in additional
shares of the same Class and automatically credited to the shareholder's account
without issuance of a share certificate unless the shareholder requests in
writing that all dividends and/or distributions be paid in cash. Shares acquired
by dividend and distribution reinvestments will not be subject to any front-end
sales charge or CDSC. Class B shares acquired through dividend and distribution
reinvestments will become eligible for conversion to Class A shares on a pro
rata basis. Distributions paid on Class A and Class D shares will be higher than
for Class B and Class C shares because distribution fees paid by Class B and
Class C shares are higher. (See "Shareholder Services -- Automatic Investment of
Dividends and Distributions.")
    
 
   
    TAXES.  Because the Fund intends to distribute all of its net investment
income and net short-term capital gains to shareholders and otherwise continue
to qualify as a regulated investment company under Subchapter M of the Internal
Revenue Code, it is not expected that the Fund will be required to pay any
federal income tax. Shareholders who are required to pay taxes on their income
will normally have to pay federal income taxes, and any state income taxes, on
the dividends and distributions they receive from the Fund. Such dividends and
distributions, to the extent that they are derived from net investment income or
net short-term capital gains, are taxable to the shareholder as ordinary income
regardless of whether the shareholder receives
such payments in additional shares or in cash. Any dividends declared in the
last quarter of any calendar year which are paid in the following year prior to
February 1 will be deemed, for tax purposes, to have been received by the
shareholder in the prior year.
    
 
    One of the requirements for the Fund to remain qualified as a regulated
investment company is that less than 30% of the Fund's gross income be derived
from gains from the sale or other disposition of securities held for less than
three months. Accordingly, the Fund may be restricted in its ability to engage
in transactions involving futures contracts.
 
    Distributions of net long-term capital gains, if any, are taxable to
shareholders as long-term capital gains regardless of how long a shareholder has
held the Fund's shares and regardless of whether the distribution is received in
additional shares or in cash. Capital gains distributions are not eligible for
the corporate dividends received deduction.
 
   
    The Fund may at times make payments from sources other than income or net
capital gains. Payments from such sources would, in effect, represent a return
of a portion of each shareholder's investment. All, or a portion, of such
payments would not be taxable to shareholders.
    
 
    After the end of the calendar year, shareholders will be sent full
information on their dividends and capital gains distributions for tax purposes.
To avoid being subject to a 31% federal backup withholding tax on taxable
dividends, capital gains distributions and the proceeds of redemptions and
repurchases,
 
                                       27
<PAGE>
shareholders' taxpayer identification numbers must be furnished and certified as
to their accuracy.
 
    Shareholders should consult their tax advisers as to the applicability of
the foregoing to their current situation.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
   
    From time to time the Fund may quote its "total return" in advertisements
and sales literature. These figures are computed separately for Class A, Class
B, Class C and Class D shares. The total return of the Fund is based on
historical earnings and is not intended to indicate future performance. The
"average annual total return" of the Fund refers to a figure reflecting the
average annualized percentage increase (or decrease) in the value of an initial
investment in a Class of the Fund of $1,000 over periods of one, five and ten
years, or over the life of the Fund, if less than any of the foregoing. Average
annual total return reflects all income earned by the Fund, any appreciation or
depreciation of the Fund's assets, all expenses incurred by the applicable Class
and all sales charges which would be incurred by shareholders, for the stated
periods. It also assumes reinvestment of all dividends and distributions paid by
the Fund.
    
 
   
    In addition to the foregoing, the Fund may advertise its total return for
each Class over different periods of time by means of aggregate, average,
year-by-year or other types of total return figures. Such calculations may or
may not reflect the deduction of any sales charge which, if reflected, would
reduce the performance quoted. The Fund may also advertise the growth of
hypothetical investments of $10,000, $50,000 and $100,000 in each Class of
shares of the Fund. The Fund from time to time may also advertise its
performance relative to certain performance rankings and indexes compiled by
independent organizations, such as mutual fund performance rankings of Lipper
Analytical Services, Inc.
    
 
ADDITIONAL INFORMATION
- --------------------------------------------------------------------------------
 
   
    VOTING RIGHTS.  All shares of beneficial interest of the Fund are of $0.01
par value and are equal as to earnings, assets and voting privileges except that
each Class will have exclusive voting privileges with respect to matters
relating to distribution expenses borne solely by such Class or any other matter
in which the interests of one Class differ from the interests of any other
Class. In addition, Class B shareholders will have the right to vote on any
proposed material increase in Class A's expenses, if such proposal is submitted
separately to Class A shareholders. Also, as discussed herein, Class A, Class B
and Class C bear the expenses related to the distribution of their respective
shares.
    
 
    The Fund is not required to hold Annual Meetings of Shareholders and in
ordinary circumstances the Fund does not intend to hold such meetings. The
Trustees may call Special Meetings of Shareholders for action by shareholder
vote as may be required by the Act or the Declaration of Trust. Under certain
circumstances, the Trustees may be removed by action of the Trustees or by the
Shareholders.
 
    Under Massachusetts law, shareholders of a business trust may, under certain
limited circumstances, be held personally liable as partners for obligations of
the Fund. However, the Declaration of Trust contains an express disclaimer of
shareholder liability for acts or obligations of the Fund, requires that Fund
obligations include such disclaimer, and provides for indemnification and
reimbursement of expenses out of the Fund's property for any shareholder held
personally liable for the obligations of the Fund. Thus, the risk of a
shareholder incurring financial loss on account of shareholder liability is
limited to circumstances in which the Fund itself would be unable to meet its
obligations. Given the above limitations on shareholder personal liability, and
the nature of the Fund's assets and operations, the possibility of the Fund
being unable to meet its
 
                                       28
<PAGE>
obligations is remote and thus, in the opinion of Massachusetts counsel to the
Fund, the risk to Fund shareholders of personal liability is remote.
 
    CODE OF ETHICS.  Directors, officers and employees of 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 sixty days of a
sale or a sale within sixty days of a purchase) of a security. In addition,
investment personnel may not purchase or sell a security for their personal
account within thirty days before or after any transaction in any Dean Witter
Fund managed by them. Any violations of the Code of Ethics are subject to
sanctions, including reprimand, demotion or suspension or termination of
employment. The Code of Ethics comports with regulatory requirements and the
recommendations in the 1994 report by the Investment Company Institute Advisory
Group on Personal Investing.
 
   
    MASTER/FEEDER CONVERSION.  The Fund reserves the right to seek to achieve
its investment objective by investing all of its investable assets in a
diversified, open-end management investment company having the same investment
objective and policies and substantially the same investment restrictions as
those applicable to the Fund.
    
 
    SHAREHOLDER INQUIRIES.  All inquiries regarding the Fund should be directed

this Prospectus.

    Dean Witter Value-Added Market Series (the "Fund") is an open-end
diversified management investment company presently consisting of a single
investment portfolio, the Equity Portfolio, whose investment objective is to

Portfolio's investment objective by investing on an equally-weighted basis in a

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
THE FUND
 
    The Fund is a Trust of the type commonly known as a "Massachusetts business
trust" and was organized under the laws of the Commonwealth of Massachusetts on
May 27, 1987.
 
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 Trustees.

    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

    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. Under the terms of the Agreement, in
addition to managing the Fund's investments, the Investment Manager maintains
certain of the Fund's books and records and furnishes, at its own expense, such
office space, facilities, equipment, clerical help, bookkeeping and certain
legal services as the Fund may reasonably require in the conduct of its
business, including the preparation of prospectuses, 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 such date. The
foregoing internal reorganizations 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 net 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 share
certificates; registration costs of the Fund and its shares under federal and
state securities laws; the cost and expense of printing, including typesetting,
and distributing Prospectuses and Statements of Additional Information of the
Fund and supplements thereto to the Fund's shareholders; all expenses of
shareholders' and Trustees' meetings and of preparing, printing and mailing of
proxy statements and reports to shareholders; fees and travel expenses of
Trustees or members of any advisory board or committee who are not employees of
the Investment Manager or any corporate affiliate of the Investment Manager; all
expenses incident to any dividend, withdrawal or redemption options; charges and
expenses of any outside service used for pricing of the Fund's shares; fees and
expenses of legal counsel, including counsel to the Trustees who are not
interested persons of the Fund or of the Investment Manager (not including
compensation or
    
 
                                       4
<PAGE>
   
expenses of attorneys who are employees of the Investment Manager) and
independent accountants; membership dues of industry associations; interest on
Fund borrowings; postage; insurance premiums on property or personnel (including
officers and Trustees) of the Fund which inure to its benefit; extraordinary
expenses (including, but not limited to, legal claims and liabilities and
litigation costs and any indemnification relating thereto); and all other costs
of the Fund's operation. The 12b-1 fees relating to a particular Class will be
allocated directly to that Class. In addition, other expenses associated with a
particular Class (except advisory or custodial fees) may be allocated directly
to that Class, provided that such expenses are reasonably identified as
specifically attributable to that Class and the direct allocation to that Class
is approved by the Trustees.
    
 
   
    As full compensation for the services and facilities furnished to the Fund
and expenses of the Fund assumed by the Investment Manager, the Fund pays the
Investment Manager monthly compensation calculated daily by applying the
following annual rates to the Fund's net assets determined as of the close of
each business day: 0.50% of the portion of daily net assets not exceeding $500
million; 0.45% of the portion exceeding $500 million but not exceeding $1
billion; and 0.425% of the portion of daily net assets exceeding $1 billion. For
the fiscal years ended June 30, 1995, 1996 and 1997, the Fund accrued to the
Investment Manager total compensation of $2,603,517, $3,897,002 and $5,253,245,
respectively.
    
 
    The Agreement provides that in the absence of willful misfeasance, bad
faith, gross negligence or reckless disregard of its obligations thereunder, the
Investment Manager is not liable to the Fund or any of its investors for any act
or omission by the Investment Manager or for any losses sustained by the Fund or
its investors. The Agreement in no way restricts the Investment Manager from
acting as investment manager or adviser to others.
 
   
    The Agreement was initially approved by the Board of Trustees on February
21, 1997 and by the shareholders of the Fund at a Meeting of Shareholders held
on May 21, 1997. The Agreement is substantially identical to a prior investment
management agreement which was initially approved by the Board of Trustees on
October 30, 1992 and by the shareholders of the Fund at a Special Meeting of
Shareholders held on January 12, 1993, as such prior agreement had been amended
by the Board of Trustees at their meetings held on April 8, 1994 and April 17,
1996 to provide breakpoints in the management fee that reduced the compensation
received by the Investment Manager under the agreement on assets exceeding $500
million and $1 billion. 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 Trustees 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 continue in effect from year to year thereafter, provided continuance of
the Agreement is approved at least annually by the vote of the holders of a
majority, as defined in the Act, of the outstanding shares of the Fund, or by
the Trustees of the Fund; provided that in either event such continuance is
approved annually by the vote of a majority of the Trustees of the Fund who are
not parties to the Agreement or "interested persons" (as defined in the Act) or
any such party (the "Independent Trustees"), which vote must be cast in person
at a meeting called for the purpose of voting on such approval.
    
 
   
    The 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 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 TRUSTEES, THE INDEPENDENT TRUSTEES, AND THE COMMITTEES
    
 
   
    The Board of Trustees currently consists of eight (8) trustees; 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 Trustees. 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 $87.9 billion and more than six million
shareholders.
    
 
   
    Six Trustees 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
    
 
                                       8
<PAGE>
   
InterCapital's parent company, MSDWD. These are the "disinterested" or
"independent" Trustees. The other two Trustees (the "management Trustees") are
affiliated with InterCapital. Four of the six independent Trustees are also
Independent Trustees of the TCW/DW Funds.
    
 
    Law and regulation establish both general guidelines and specific duties for
the Independent Trustees. The Dean Witter Funds seek as Independent Trustees
individuals of distinction and experience in business and finance, government
service or academia; these are people whose advice and counsel are in demand by
others and for whom there is often competition. To accept a position on the
Funds' Boards, such individuals may reject other attractive assignments because
the Funds make substantial demands on their time. Indeed, by serving on the
Funds' Boards, certain Trustees who would otherwise be qualified and in demand
to serve on bank boards would be prohibited by law from doing so.
 
   
    All of the current Independent Trustees serve as members of the Audit
Committee and the Committee of the Independent Trustees. 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 Trustees 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 Trustees is charged with recommending to
the full Board approval of management, advisory and administration contracts,
Rule 12b-1 plans and distribution and underwriting agreements; continually
reviewing Fund performance; checking on the pricing of portfolio securities,
brokerage commissions, transfer agent costs and performance, and trading among
Funds in the same complex; and approving fidelity bond and related insurance
coverage and allocations, as well as other matters that arise from time to time.
The Independent Trustees are required to select and nominate individuals to fill
any Independent Trustee vacancy on the Board of any Fund that has a Rule 12b-1
plan of distribution. Most of the 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 TRUSTEES AND AUDIT COMMITTEE
 
    The Chairman of the Committee of the Independent Trustees 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 Trustees 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 Trustees and with
the Funds' independent auditors. He
 
                                       9
<PAGE>
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 Trustees.
 
    The Chairman of the Committee of the Independent Trustees 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
Trustee of the Dean Witter Funds and as an Independent Trustee 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 TRUSTEES FOR ALL DEAN
WITTER FUNDS
 
    The Independent Trustees and the Funds' management believe that having the
same Independent Trustees for each of the Dean Witter Funds avoids the
duplication of effort that would arise from having different groups of
individuals serving as Independent Trustees for each of the Funds or even of
sub-groups of Funds. They believe that having the same individuals serve as
Independent Trustees of all the Funds tends to increase their knowledge and
expertise regarding matters which affect the Fund complex generally and enhances
their ability to negotiate on behalf of each Fund with the Fund's service
providers. This arrangement also precludes the possibility of separate groups of
Independent Trustees arriving at conflicting decisions regarding operations and
management of the Funds and avoids the cost and confusion that would likely
ensue. Finally, having the same Independent Trustees serve on all Fund Boards
enhances the ability of each Fund to obtain, at modest cost to each separate
Fund, the services of Independent Trustees, and a Chairman of their Committees,
of the caliber, experience and business acumen of the individuals who serve as
Independent Trustees of the Dean Witter Funds.
 
COMPENSATION OF INDEPENDENT TRUSTEES
 
    The Fund pays each Independent Trustee an annual fee of $1,000 plus a per
meeting fee of $50 for meetings of the Board of Trustees or committees of the
Board of Trustees attended by the Trustee (the Fund pays the Chairman of the
Audit Committee an annual fee of $750 and pays the Chairman of the Committee of
the Independent Trustees an additional annual fee of $1,200). The Fund also
reimburses such Trustees for travel and other out-of-pocket expenses incurred by
them in connection with attending such meetings. Trustees and officers of the
Fund who are or have been employed by the Investment Manager or an affiliated
company receive no compensation or expense reimbursement from the Fund.

Independent Trustees by the Fund for the fiscal year ended June 30, 1997.

    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 Trustee who retires after serving for at least five years (or
such lesser period as may be determined by the Board) as an Independent Director
or Trustee of any Dean Witter Fund that has adopted the retirement program (each
such Fund referred to as an "Adopting Fund" and each such Trustee referred to as
an "Eligible Trustee") is entitled to retirement payments upon reaching the
eligible retirement age (normally, after attaining age 72). Annual payments are
based upon length of service. Currently, upon retirement, each Eligible Trustee
is entitled to receive from the Adopting Fund, commencing as of his or her
retirement date and continuing for the remainder of his or her life, an annual
retirement benefit (the "Regular Benefit") equal to 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 Trustee for service to the
Adopting Fund in the five year period prior to the date of the Eligible
Trustee's retirement. Benefits under the retirement program are not secured or
funded by the Adopting Funds.
 
- ------------------------
 
   
(1) An Eligible Trustee may elect alternate payments of his or her retirement
    benefits based upon the combined life expectancy of such Eligible Trustee
    and his or her spouse on the date of such Eligible Trustee's retirement. The
    amount estimated to be payable under this method, through the remainder of
    the later of the lives of such Eligible Trustee and spouse, will be the
    actuarial equivalent of the Regular Benefit. In addition, the Eligible
    Trustee may elect that the surviving spouse's periodic payment of benefits
    will be equal to either 50% or 100% of the previous periodic amount, an
    election that, respectively, increases or decreases the previous periodic
    amount so that the resulting payments will be the actuarial equivalent of
    the Regular Benefit.

INVESTMENT PRACTICES AND POLICIES
- --------------------------------------------------------------------------------
 
LENDING OF PORTFOLIO SECURITIES
 
    Consistent with applicable regulatory requirements, the Fund may lend its
portfolio securities to brokers, dealers and other financial institutions,
provided that such loans are callable at any time by the Fund (subject to notice
provisions described below), and are at all times secured by cash or cash
equivalents, which are maintained in a segregated account pursuant to applicable
regulations and that are equal to at least the market value, determined daily,
of the loaned securities. The advantage of such loans is that the Fund continues
to receive the income on the loaned securities while at the same time earning
interest on the cash amounts deposited as collateral, which will be invested in
short-term obligations. The Fund will not lend its portfolio securities if such
loans are not permitted by the laws or regulations of any state in which its
shares are qualified for sale and will not lend more than 25% of the value of
its total assets. A loan may be terminated by the borrower on one business day's
notice, or by the Fund on four business days' notice. If the borrower fails to
deliver the loaned securities within four days after receipt of notice, the Fund
could use the collateral to replace the securities while holding the borrower
liable for any excess of replacement cost over collateral. As with any
extensions of credit, there are risks of delay in recovery and in some cases
even loss of rights in the collateral should the borrower of the securities fail
financially. However, these loans of portfolio securities will only be made to
firms deemed by the Fund's management to be creditworthy and when the income
which can be earned from such 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
 
                                       12
<PAGE>
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 Fund's
Trustees.
 
    When voting or consent rights which accompany loaned securities pass to the
borrower, however, the Fund will follow the policy of calling the loaned
securities, to be delivered within one day after notice, to permit the exercise
of such rights if the matters involved would have a material effect on the
Fund's investment in such loaned securities. The Fund will pay reasonable
finder's, administrative and custodial fees in connection with a loan of its
securities. However, the Fund does not presently intend to lend any of its
portfolio securities in the forseeable future.
 
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. A repurchase agreement may be
viewed as a type of secured lending by the Fund which typically involves the
acquisition by the Fund of government securities from a selling financial
institution such as a bank, savings and loan association or broker-dealer. The
agreement provides that the Fund will sell back to the institution, and that the
institution will repurchase, the underlying security ("collateral") at a
specified price and at a fixed time in the future, usually not more than seven
days from the date of purchase. The collateral will be maintained in a
segregated account and will be marked to market daily to determine that the
value of the collateral, as specified in the agreement, does not decrease below
the purchase price plus accrued interest. If such decrease occurs, additional
collateral will be requested and, when received, added to the account to
maintain full collateralization. The Fund will accrue interest from the
institution until the time when the repurchase is to occur. Although such date
is deemed by the Fund to be the maturity date of a repurchase agreement, the
maturities of securities subject to repurchase agreements are not subject to any
limits.
 
    While repurchase agreements involve certain risks not associated with direct
investments in debt securities, the Fund follows procedures designed to minimize
such risks. These procedures include effecting repurchase transactions only with
large, well-capitalized and well-established financial institutions whose
financial condition will be continually monitored by the Investment Manager
subject to procedures established by the Board of Trustees of the Fund. In
addition, as described above, the value of the collateral underlying the
repurchase agreement will 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.
 
FUTURES CONTRACTS
 
    As discussed in the Prospectus, the Fund may invest in stock index futures
contracts. A stock index futures contract is a bilateral agreement pursuant to
which two parties agree to take or make delivery of an amount of cash equal to a
specified dollar amount times the difference between the stock index value at
the close of the last trading day of the contract and the futures contract
price. Futures contracts on stock indexes do not involve the physical delivery
of securities, but provide for a final cash settlement on the expiration date
which reflects accumulated profits and losses credited or debited to each
party's account. It should be recognized that the use of futures contracts
involves skills different from those used in selecting portfolio securities.
 
    The Fund is required to maintain margin deposits with brokerage firms
through which it effects index futures contracts. 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.
 
                                       13
<PAGE>
    At any time prior to expiration of the futures contract, the Fund may elect
to close the position by taking an opposite position which will operate to
terminate the Fund's position in the futures contract. A final determination of
variation margin is then made, additional cash is required to be paid by or
released to the Fund and the Fund realizes a loss or a gain.
 
    Currently, stock index futures contracts can be purchased or sold with
respect to, among others, the Standard & Poor's 500 Composite Stock Price Index
and the Standard & Poor's 100 Composite Stock Price Index on the Chicago
Mercantile Exchange, the New York Stock Exchange Composite Index on the New York
Futures Exchange, the Major Market Index on the American Stock Exchange and the
Value Line Stock Index on the Kansas City Board of Trade.
 
PRIVATE PLACEMENTS
 
    The Fund may invest up to 10% 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. 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 Trustees of the Fund, will make a
determination as to the liquidity of each restricted security purchased by the
Fund. If a restricted security is determined to be "liquid," such security will
not be included within the category "illiquid securities," which is limited by
the Fund's investment restrictions to 10% of the Fund's total assets.
 
PORTFOLIO TURNOVER
 
    It is anticipated that the Fund's portfolio turnover rate will not exceed
100%. A 100% turnover rate would occur, for example, if 100% of the securities
held in the Fund's portfolio (excluding all securities whose maturities at
acquisition were one year or less) were sold and replaced within one year.
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    In addition to the investment restrictions enumerated in the Prospectus, the
investment restrictions listed below have been adopted by the Fund as
fundamental policies, except as otherwise indicated. Under the Act, a
fundamental policy may not be changed without the vote of a majority of the
outstanding voting securities of the Fund, as defined in the Act. Such a
majority is defined as the lesser of (a) 67% or more of the shares present at a
meeting of shareholders, if the holders of 50% of the outstanding shares of the
Fund are present or represented by proxy or (b) more than 50% of the outstanding
shares of the Fund.
 
    The Fund may not:
 
         1. Invest in securities of any issuer if, to the knowledge of the Fund,
    any officer or trustee/ director of the Fund or of the Investment Manager
    owns more than 1/2 of 1% of the outstanding securities of such issuer, and
    such officers and trustees/directors who own more than 1/2 of 1% own in the
    aggregate more than 5% of the outstanding securities of such issuers.
 
         2. Purchase or sell real estate or interests therein, although the Fund
    may purchase securities of issuers which engage in real estate operations
    and securities secured by real estate or interests therein.
 
         3. Purchase or sell commodities except that the Fund may purchase or
    sell (write) futures contracts and related options.
 
                                       14
<PAGE>
         4. Purchase oil, gas or other mineral leases, rights or royalty
    contracts or exploration or development programs, except that the Fund may
    invest in the securities of companies which operate, invest in, or sponsor
    such programs.
 
         5. Purchase securities of other investment companies, except in
    connection with a merger, consolidation, reorganization or acquisition of
    assets.
 
         6. Borrow money, except that the Fund may borrow from a bank for
    temporary or emergency purposes in amounts not exceeding 5% (taken at the
    lower of cost or current value) of its total assets (not including the
    amount borrowed).
 
         7. Pledge its assets or assign or otherwise encumber them except to
    secure borrowings effected within the limitations set forth in restriction
    (6). For the purpose of this restriction, collateral arrangements with
    respect to the writing of options and collateral arrangements with respect
    to initial or variation margin for futures are not deemed to be pledges of
    assets.
 
         8. Issue senior securities as defined in the Act except insofar as the
    Fund may be deemed to have issued a senior security by reason of borrowing
    money in accordance with restrictions described above.
 
         9. Make loans of money or securities, except: (a) by the purchase of
    publicly distributed debt obligations in which the Fund may invest
    consistent with its investment objective and policies; (b) by investment in
    repurchase agreements; or (c) by lending its portfolio securities.
 
        10. Make short sales of securities.
 
        11. Purchase securities on margin, except for such short-term loans as
    are necessary for the clearance of portfolio securities. The deposit or
    payment by the Fund of initial or variation margin in connection with
    futures contracts or related options thereon is not considered the purchase
    of a security on margin.
 
        12. Invest more than 10% of its total assets in "illiquid securities"
    (securities for which market quotations are not readily available),
    restricted securities and repurchase agreements which have a maturity of
    longer than seven days.
 
        13. Engage in the underwriting of securities, except insofar as the Fund
    may be deemed an underwriter under the Securities Act of 1933 in disposing
    of a portfolio security.
 
        14. Invest for the purpose of exercising control or management of any
    other issuer.
 
    If a percentage restriction is adhered to at the time of investment, a later
increase or decrease in percentage resulting from a change in values of
portfolio securities or amount of total or net assets will not be considered a
violation of any of the foregoing restrictions.
 
   
    Notwithstanding any other investment policy or restriction, the Fund may
seek to achieve its investment objective by investing all or substantially all
of its assets in another investment company having substantially the same
investment objective and policies as the Fund.
    
 
PORTFOLIO TRANSACTIONS AND BROKERAGE
- --------------------------------------------------------------------------------
 
    Subject to the general supervision of the Trustees, the Investment Manager
is responsible for decisions to buy and sell securities for the Fund, the
selection of brokers and dealers to effect the transactions, and the negotiation
of brokerage commissions, if any. Purchases and sales of securities on a stock
exchange are effected through brokers who charge a commission for their
services. In the over-the-counter market, securities are generally traded on a
"net" basis with dealers acting as principal for their own accounts without a
stated commission, although the price of the security usually includes a profit
to the dealer. Futures transactions are usually effected through a broker and a
commission will be charged. On occasion, the Fund may also purchase certain
money market instruments directly from an
 
                                       15
<PAGE>
   
issuer, in which case no commissions or discounts are paid. During the fiscal
years ended June 30, 1995, 1996 and 1997, the Fund paid a total of $204,236,
$311,923 and $343,521, respectively, in brokerage commissions.
    
 
   
    The Investment Manager currently serves as investment manager to a number of
clients, including other investment companies, and may in the future act as
investment manager or adviser to others. It is the practice of the Investment
Manager to cause purchase and sale transactions to be allocated among the Fund
and others whose assets it manages in such manner as it deems equitable. In
making such 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 for its
portfolio is that primary consideration will be given to obtaining the most
favorable prices and efficient executions of transactions. Consistent with this
policy, when securities transactions are effected on a stock exchange, the
Fund's policy is to pay commissions which are considered fair and reasonable
without necessarily determining that the lowest possible commissions are paid in
all circumstances. The Fund believes that a requirement always to seek the
lowest possible commission cost could impede effective portfolio management and
preclude the Fund and the Investment Manager from obtaining a high quality of
brokerage and research services. In seeking to determine the reasonableness of
brokerage commissions paid in any transaction, the Investment Manager relies
upon its experience and knowledge regarding commissions generally charged by
various brokers and on its judgment in evaluating the brokerage and research
services received from the broker effecting the transaction. Such determinations
are necessarily subjective and imprecise, as in most cases an exact dollar value
for those services is not ascertainable.
 
    In seeking to implement the Fund's policies, the Investment Manager effects
transactions with those brokers and dealers who the Investment Manager believes
provide the most favorable prices and are capable of providing efficient
executions. If the Investment Manager believes such prices and executions are
obtainable from more than one broker or dealer, it may give consideration to
placing portfolio transactions with those brokers and dealers who also furnish
research and other services to the Fund or the Investment Manager. Such services
may include, but are not limited to, any one or more of the following:
information as to the availability of securities for purchase or sale;
statistical or factual information or opinions pertaining to 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 the Investment Manager and thereby reduce its expenses,
it is of indeterminable value and the management fee paid to the Investment
Manager is not reduced by any amount that may be attributable to the value of
such services.
 
   
    Pursuant to an order of the Securities and Exchange Commission, the Fund may
effect principal transactions in certain money market instruments with DWR. The
Fund will limit its transactions with DWR to U.S. Government and Government
Agency Securities, Bank Money Instruments (i.e., Certificates of Deposit and
Bankers' Acceptances) and Commercial Paper. Such transactions will be effected
with DWR only when the price available from DWR is better than that available
from other dealers. During the fiscal years ended June 30, 1995, 1996 and 1997,
the Fund did not effect any principal transactions with DWR.
    
 
                                       16
<PAGE>
   
    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 any portfolio transactions for the Fund,
the commissions, fees or other remuneration received by the affiliated broker or
dealer must be reasonable and fair compared to the commissions, fees or other
remuneration paid to other brokers in connection with comparable transactions
involving similar securities being purchased or sold on an exchange during a
comparable period of time. This standard would allow the affiliated broker or
dealer to receive no more than the remuneration which would be expected to be
received by an unaffiliated broker in a commensurate arm's-length transaction.
Furthermore, the Board of Trustees of the Fund, including a majority of the
Trustees who are not "interested" persons of the Fund, as defined in the Act,
have adopted procedures which are reasonably designed to provide that any
commissions, fees or other remuneration paid to an affiliated broker or dealer
are consistent with the foregoing standard. The Fund does not reduce the
management fee it pays to the Investment Manager by the amount of any brokerage
commissions it may pay to an affiliated broker or dealer. During the fiscal year
ended June 30, 1995, the Fund paid a total of $1,540 in brokerage commissions to
DWR. The Fund did not pay any brokerage commissions to any affiliated brokers or
dealers during the fiscal years ended June 30, 1996 and 1997.
    
 
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 selected
dealer agreements with other selected broker-dealers. The Distributor, a
Delaware corporation, is a wholly-owned subsidiary of MSDWD. The Trustees of the
Fund, including a majority of the Trustees who are not, and were not at the time
they voted, "interested persons" of the Fund, as defined in the Act (the
"Independent Trustees"), approved, at their meeting held on June 30, 1997, the
current Distribution Agreement appointing the Distributor exclusive distributor
of the Fund's shares and providing for the Distributor to bear distribution
expenses not borne by the Fund. By its terms, the Distribution Agreement has an
initial term ending April 30, 1998 and will remain in effect from year to year
thereafter if approved by the Trustees.
    
 
   
    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 will also pay 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 will bear the costs of registering the Fund and
its shares under federal securities laws and pays filing fees in accordance with
state securities laws. The Fund and the Distributor have agreed to indemnify
each other against certain liabilities, including liabilities under the
Securities Act of 1933, as amended. Under the Distribution Agreement, the
Distributor uses its best efforts in rendering services to the Fund, but in the
absence of willful misfeasance, bad faith, gross negligence or reckless
disregard of its obligations, the Distributor is not liable to the Fund or any
of its shareholders for any error of judgment or mistake of law or any act or
omission or for any losses sustained by the Fund or its shareholders.
    
 
PLAN OF DISTRIBUTION
 
   
    The Fund has adopted a Plan of Distribution pursuant to Rule 12b-1 under the
Act (the "Plan") pursuant to which each Class, other than Class D, pays the
Distributor compensation accrued daily and payable monthly at the following
annual rates: 0.25% and 1.0% of the average daily net assets of Class A and
Class C, respectively, and, with respect to Class B, 1.0% of the lesser of: (a)
the average daily aggregate gross sales of the Fund's Class B shares since the
inception of the Fund (not including reinvestments of dividends or capital gains
distributions), less the average daily aggregate net asset value of the Fund's
Class B shares redeemed since the Fund's inception upon which a contingent
    
 
                                       17
<PAGE>
   
deferred sales charge has been imposed or upon which such charge has been
waived; or (b) the average daily net assets of Class B. The Distributor also
receives the proceeds of front-end sales charges and of contingent deferred
sales charges imposed on certain redemptions of shares, which are separate and
apart from payments made pursuant to the Plan (see "Purchase of Fund Shares" in
the Prospectus). The Distributor has informed the Fund that it and/or DWR
received approximately $716,000, $831,000 and $1,243,000 in contingent deferred
sales charges for the fiscal years ended June 30, 1995, 1996 and 1997,
respectively, none of which was retained by the Distributor.
    
 
   
    The Distributor has informed the Fund that the entire fee payable by Class A
and a portion of the fees payable by each of Class B and Class C each year
pursuant to the Plan equal to 0.25% of such Class's average daily net assets are
currently each characterized as a "service fee" under the Rules of the
Association of the National Association of Securities Dealers, Inc. (of which
the Distributor is a member). The "service fee" is a payment made for personal
service and/or the maintenance of shareholder accounts. The remaining portion of
the Plan fees payable by a Class, if any, is characterized as an "asset-based
sales charge" as such is defined by the aforementioned Rules of the Association.
    
 
   
    The Plan was adopted by a vote of the Trustees of the Fund on July 29, 1987,
at a Meeting of the Trustees called for the purpose of voting on such Plan. The
vote included the vote of a majority of the Trustees of the Fund who are not
"interested persons" of the Fund (as defined in the Act) and who have no direct
or indirect financial interest in the operation of the Plan (the "Independent
12b-1 Trustees"). DWR, as the then sole shareholder of the Fund, approved the
Plan on September 21, 1987, whereupon the Plan went into effect. The Plan was
approved by shareholders of the Fund at a Meeting of Shareholders on December
29, 1988.
    
 
   
    At their meeting held on October 30, 1992, the Trustees of the Fund,
including all of the Independent 12b-1 Trustees, approved certain amendments to
the Plan which took effect in January, 1993 and were designed to reflect the
fact that upon an internal reorganization the share distribution activities
theretofore performed for the Fund by DWR were assumed by the Distributor and
DWR's sales activities are now being performed pursuant to the terms of a
selected dealer agreement between the Distributor and DWR. The amendments
provide that payments under the Plan will be made to the Distributor rather than
to DWR as before the amendment, and that the Distributor in turn is authorized
to make payments to DWR, its affiliates or other selected broker-dealers (or
direct that the Fund pay such entities directly). The Distributor is also
authorized to retain part of such fee as compensation for its own
distribution-related expenses. At their meeting held on April 28, 1993, the
Trustees, including a majority of the Independent 12b-1 Trustees, also approved
certain technical amendments to the Plan in connection with amendments adopted
by the National Association of Securities Dealers, Inc. to its Rules of the
Association. At their meeting held on April 14, 1994, the shareholders of the
Fund approved an amendment to the Plan to permit payments to be made under the
Plan with respect to distribution expenses incurred in connection with the
distribution of shares of an investment company whose assets are acquired by the
Fund in a tax-free reorganization. At their meeting held on June 30, 1997, the
Trustees, including a majority of the Independent 12b-1 Trustees, approved
amendments to the Plan to reflect the multiple-class structure for the Fund,
which took effect on July 28, 1997.
    
 
   
    Under the Plan and as required by Rule 12b-1, the Trustees will receive and
review promptly after the end of each fiscal quarter a written report provided
by the Distributor of the amounts expended by the Distributor under the Plan and
the purpose for which such expenditures were made. The Fund accrued amounts
payable to the Distributor under the Plan, during the fiscal year ended June 30,
1997, of $9,411,862. This amount is equal to 0.84% of the Fund's average daily
net assets for the fiscal year and was calculated pursuant to clause (a) of the
compensation formula under the Plan. This amount is treated by the Fund as an
expense in the year it is accrued. This amount represents amounts paid by Class
B only; there were no Class A or Class C shares outstanding on such date.
    
 
   
    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.
    
 
                                       18
<PAGE>
   
    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 5.0% of the
amount sold (except as provided in the following sentence) and an annual
residual commission, currently a residual of up to 0.25% of the current value of
the respective accounts for which they are the 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 5.0% of the amount sold (except as
provided in the following sentence) and an annual residual commission, currently
a residual of up to 0.25% of the current value (not including reinvested
dividends or distributions) of the amount sold in all cases. In the case of
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 1.0% 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 share sales. The distribution fee
that the Distributor receives from the Fund under the Plan, in effect, offsets
distribution expenses incurred on behalf of the Fund and, in the case of Class B
shares, opportunity costs, such as the gross sales credit and an assumed
interest charge thereon ("carrying charge"). In the Distributor's reporting of
the distribution expenses to the Fund, in the case of Class B shares, such
assumed interest (computed at the "broker's call rate") has been calculated on
the gross sales credit as it is reduced by amounts received by the Distributor
under the Plan and any contingent deferred sales charges received by the
Distributor upon redemption of shares of the Fund.
    
 
                                       19
<PAGE>
No other interest charge is included as a distribution expense in the
Distributor's calculation of 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 paid 100% of the $9,411,862 accrued under the Plan for the fiscal
year ended June 30, 1997 to the Distributor. The Distributor and DWR estimate
that they have spent, pursuant to the Plan, $97,963,119 on behalf of the Fund
since the inception of the Plan. It is estimated that this amount was spent in
approximately the following ways: (i) 4.73% ($4,630,793) -- advertising and
promotional expenses; (ii) 0.24% ($235,216) -- printing of prospectuses for
distribution to other than current shareholders; and (iii) 95.03% ($93,097,110)
- -- other expenses, including the gross sales credit and the carrying charge, of
which 9.98% ($9,291,308) represents carrying charges, 23.77% ($22,131,858)
represents commission credits to DWR branch offices for payments of commissions
to account executives, 35.77% ($33,294,784) represents overhead and other branch
office distribution-related expenses, and 30.48% ($28,379,160) represents excess
distribution expenses of Dean Witter Equity Income Trust, the net assets of
which were combined with those of the Fund on April 18, 1994 pursuant to an
Agreement and Plan of Reorganization. These amounts represent amounts paid by
Class B only; there were no Class A or Class C shares outstanding on such date.
    
 
   
    The Fund is authorized to reimburse expenses incurred or to be incurred in
promoting the distribution of the Fund's Class A and Class C shares and in
servicing shareholder accounts. Reimbursement will be made through payments at
the end of each month. The amount of each monthly payment may in no event exceed
an amount equal to a payment at the annual rate of 0.25%, in the case of Class
A, and 1.0%, in the case of Class C, of the average net assets of the respective
Class during the month. No interest or other financing charges, if any, incurred
on any distribution expenses on behalf of Class A and Class C will be
reimbursable under the Plan. With respect to Class A, in the case of all
expenses other than expenses representing the service fee, and, with respect to
Class C, in the case of all expenses other than expenses representing a gross
sales credit or a residual to account executives, such amounts shall be
determined at the beginning of each calendar quarter by the Trustees, including
a majority of the Independent 12b-1 Trustees. Expenses representing the service
fee (for Class A) or a gross sales credit or a residual to 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 quarterly determinations of the amounts that may be
reimbursed by the Fund, the Distributor will provide and the Trustees will
review a quarterly budget of projected distribution expenses to be incurred on
behalf of the Fund, together with a report explaining the purposes and
anticipated benefits of incurring such expenses. The Trustees will determine
which particular expenses, and the portions thereof, that may be borne by the
Fund, and in making such a determination shall consider the scope of the
Distributor's commitment to promoting the distribution of the Fund's Class A and
Class C shares.
    
 
   
    At any given time the expenses in 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. The Distributor has advised the Fund that
in the case of Class B shares such excess amount, including the carrying charge
designed to approximate the opportunity costs incurred by DWR which arise from
it having advanced monies without having received the amount of any sales
charges imposed at the time of sale of the Fund's Class B shares, totalled
$61,114,557 as of June 30, 1997. Of this amount, $28,379,160 represents excess
distribution expenses of Dean Witter Equity Income Trust, the net assets of
which, as noted above, have been combined with those of the Fund. 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
distribution expenses in excess of payments made to the Distributor under the
Plan and the proceeds of contingent deferred sales charges paid by investors
upon redemption of shares, if for any reason the Plan is terminated, the
Trustees will consider at that time the
    
 
                                       20
<PAGE>
manner in which to treat such expenses. Any cumulative expenses incurred, but
not yet recovered through distribution fees or contingent deferred sales
charges, may or may not be recovered through future distribution fees or
contingent deferred sales charges.
 
   
    No interested person of the Fund, nor any Trustee of the Fund who is not an
interested person of the Fund, as defined in the Act, had any direct or indirect
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.
    
 
   
    Under its terms, the Plan had an initial term ending April 30, 1988 and will
continue from year to year thereafter, provided such continuance is approved
annually by a vote of the Trustees in the manner described above. Prior to the
Board's approval of amendments to the Plan to reflect the multiple-class
structure for the Fund, the most recent continuation of the Plan for one year,
until April 30, 1998, was approved by the Trustees of the Fund, including all of
the Independent 12b-1 Trustees, at a meeting held on April 24, 1997. Prior to
approving the continuation of the Plan, the Trustees requested and received from
the Distributor and reviewed all the information which they deemed necessary to
arrive at an informed determination. In making their determination to continue
the Plan, the Trustees considered: (1) the Fund's experience under the Plan and
whether such experience indicates that the Plan is operating as anticipated; (2)
the benefits the Fund had obtained, was obtaining and would be likely to obtain
under the Plan; and (3) what services had been provided and were continuing to
be provided under the Plan to the Fund and its shareholders. Based upon their
review, the Trustees of the Fund, including each of the Independent 12b-1
Trustees, determined that continuation of the Plan would be in the best interest
of the Fund and would have a reasonable likelihood of continuing to benefit the
Fund and its shareholders. In the Trustees' quarterly review of the Plan, they
will consider its continued appropriateness and the level of compensation
provided therein.
    
 
   
    The Plan may not be amended to increase materially the amount to be spent
for the services described therein without approval of the shareholders of the
affected Class or Classes of the Fund, and all material amendments of the Plan
must also be approved by the Trustees in the manner described above. The Plan
may be terminated at any time, without payment of any penalty, by vote of a
majority of the Independent 12b-1 Trustees or by a vote of a majority of the
outstanding voting securities of the Fund (as defined in the Act) 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 Trustees shall be
committed to the discretion of the Independent 12b-1 Trustees.
    
 
   
DETERMINATION OF NET ASSET VALUE
    
- --------------------------------------------------------------------------------
 
    As stated in the Prospectus, short-term securities with remaining maturities
of sixty days or less at the time of purchase are valued at amortized cost,
unless the Trustees determine such does not reflect the securities' market
value, in which case these securities will be valued at their fair value as
determined by the Trustees. Other short-term debt securities will be valued on a
mark-to-market basis until such time as they reach a remaining maturity of sixty
days, whereupon they will be valued at amortized cost using their value on the
61st day unless the Trustees determine such does not reflect the securities'
market value, in which case these securities will be valued at their fair value
as determined by the Trustees. Futures are valued at the latest sale price on
the commodities exchange on which they trade unless the Trustees determine such
price does not reflect their market value, in which case they will be valued at
their fair value as determined by the Trustees. All other securities and other
assets are valued at their fair value as determined in good faith under
procedures established by and under the supervision of the Trustees.
 
   
    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

PURCHASE OF FUND SHARES
    
- --------------------------------------------------------------------------------
 
   
    As discussed in the Prospectus, the Fund offers four Classes of shares as
follows:
    
 
   
INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES
    
 
   
    Class A shares are sold to investors with an initial sales charge that
declines to zero for larger purchases; however, Class A shares sold without an
initial sales charge are subject to a contingent deferred sales charge ("CDSC")
of 1.0% if redeemed within one year of purchase, except in the circumstances
discussed in the Prospectus.
    
 
   
    RIGHT OF ACCUMULATION.  As discussed in the Prospectus, investors may
combine the current value of shares purchased in separate transactions for
purposes of 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 4.75% of
the offering price.
    
 
   
    The Distributor must be notified by the selected broker-dealer or the
shareholder at the time a purchase order is placed that the purchase qualifies
for the reduced charge under the Right of Accumulation. Similar notification
must be made in writing by the selected broker-dealer or shareholder when such
an order is placed by mail. The reduced sales charge will not be granted if: (a)
such notification is not furnished at the time of the order; or (b) a review of
the records of the Distributor or 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
    
 
                                       22
<PAGE>
   
(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.
    
 
   
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,
    
 
                                       23
<PAGE>
   
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 and maintained by the Transfer
Agent. This is an open account in which shares owned by the investor are
credited by the Transfer Agent in lieu of issuance of a share certificate. If a
share certificate is desired, it must be requested in writing for each
transaction. Certificates are issued only for full shares and may be redeposited
in the account at any time. There is no charge to the investor for issuance of a
certificate. Whenever a shareholder-instituted transaction takes place in the
Shareholder Investment Account, the shareholder will be mailed a confirmation of
the transaction from the Fund or from DWR or other selected broker-dealer.
    
 
    AUTOMATIC INVESTMENT OF DIVIDENDS AND DISTRIBUTIONS.  As stated in the
Prospectus, all income dividends and capital gains distributions are
automatically paid in full and fractional shares of the
 
                                       24
<PAGE>
   
applicable Class of the Fund, unless the shareholder requests that they be paid
in cash. Each purchase of shares of the Fund is made upon the condition that the
Transfer Agent is thereby automatically appointed as agent of the investor to
receive all dividends and capital gains distributions on shares owned by the
investor. Such dividends and distributions will be paid, at the net asset value
per share, in shares of the applicable Class of the Fund (or in cash if the
shareholder so requests) as of the close of business on the record date. At any
time an investor may request the Transfer Agent, in writing, to have subsequent
dividends and/or capital gains distributions paid to him or her in cash rather
than shares. To assure sufficient time to process the change, such request
should be received by the Transfer Agent at least five business days prior to
the record date of the dividend or distribution. In the case of recently
purchased shares for which registration instructions have not been received on
the record date, cash payments will be made to the Distributor, which 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 a Dean Witter Fund other than
Dean Witter Value-Added Market Series or in another Class of Dean Witter Value-
Added Market Series. Such investment will be made as described above for
automatic investment in shares 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 DIVIDENDS OR DISTRIBUTIONS RECEIVED IN CASH.  As discussed in
the Prospectus, any shareholder who receives a cash payment representing a
dividend or distribution may invest such dividend or distribution in shares of
the applicable Class at net asset value, without the imposition of a CDSC upon
redemption, by returning the check or the proceeds to the Transfer Agent within
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 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 net asset value. The Withdrawal Plan provides for monthly or
quarterly (March, June, September and December) checks in any dollar amount, not
less than $25, or in any whole percentage of the account balance, on an
annualized basis. Any applicable CDSC will be imposed on shares redeemed under
the Withdrawal Plan (see "Purchase of Fund Shares" in the Prospectus).
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
 
                                       25
<PAGE>
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").
    
 
    Any shareholder who wishes to have payments under the Withdrawal Plan made
to a third party or sent to an address other than the one listed on the account
must send complete written instructions to the Transfer Agent to enroll in the
Withdrawal Plan. The shareholder's signature on such instructions must be
guaranteed by an eligible guarantor acceptable to the Transfer Agent
(shareholders should contact the Transfer Agent for a determination as to
whether a particular institution is such an eligible guarantor). A shareholder
may, at any time, change the amount and interval of withdrawal payments through
his or her 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. Shareholders wishing to enroll in
the Withdrawal Plan should contact their account executive or the Transfer
Agent.
 
   
    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 Value-Added Market Series, 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 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 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
    
 
                                       26
<PAGE>
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 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, if any, 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 charge 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
    
 
                                       27
<PAGE>
   
value of, the exchanged non-Free Shares. If an exchange between funds would
result in exchange of only part of a particular block of non-Free Shares, then
shares equal to any appreciation in the value of the block (up to the amount of
the exchange) will be treated as Free Shares and exchanged first, and the
purchase payment for that block will be allocated on a pro rata basis between
the non-Free Shares of that block to be retained and the non-Free Shares to be
exchanged. The prorated amount of such purchase payment attributable to the
retained non-Free Shares will remain as the purchase payment for such shares,
and the amount of purchase payment for the exchanged non-Free Shares will be
equal to the lesser of (a) the prorated amount of the purchase payment for, or
(b) the current net asset value of, those exchanged non-Free Shares. Based upon
the procedures described in the Prospectus under the caption "Purchase of Fund
Shares," any applicable CDSC will be imposed upon the ultimate redemption of
shares of any fund, regardless of the number of exchanges since those shares
were originally purchased.
    
 
    With respect to the redemption or repurchase of shares of the Fund, the
application of proceeds to the purchase of new shares in the Fund or any other
of the funds and the general administration of the Exchange Privilege, the
Transfer Agent acts as agent for the Distributor and for the shareholder's
selected broker-dealer, if any, in the performance of such functions. With
respect to exchanges, redemptions or repurchases, the Transfer Agent shall be
liable for its own negligence and not for the default or negligence of its
correspondents or for losses in transit. The Fund shall not be liable for any
default or negligence of the Transfer Agent, the Distributor or any selected
broker-dealer.
 
    The Distributor and any selected broker-dealer have authorized and appointed
the Transfer Agent to act as their agent in connection with the application of
proceeds of any redemption of Fund shares to the purchase of shares of any other
fund and the general administration of the Exchange Privilege. No commission or
discounts will be paid to the Distributor or any selected broker-dealer for any
transactions pursuant to this Exchange Privilege.
 
   
    Exchanges are subject to the minimum investment requirement and any other
conditions imposed by each fund. (The minimum initial investment for the
Exchange Privilege account of each Class is $5,000 for Dean Witter Liquid Asset
Fund Inc., Dean Witter Tax-Free Daily Income Trust, Dean Witter California
Tax-Free Daily Income Trust and Dean Witter New York Municipal Money Market
Trust although those funds may, at their discretion, accept initial investments
of as low as $1,000. The minimum 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, in its discretion, accept initial purchases 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 agencies (presently sixty days' prior written notice for
termination or material revision), provided that six months' prior written
notice of termination will be given to 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
 
                                       28
<PAGE>
permits (provided that applicable rules and regulations of the Securities and
Exchange Commission shall govern as to whether the conditions prescribed in (b)
or (c) exist) or (e) if the Fund would be unable to invest amounts effectively
in accordance with its investment objective, policies and restrictions.
 
    For further information regarding the Exchange Privilege, shareholders
should contact their DWR or other selected broker-dealer account executive or
the Transfer Agent.
 
REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 
   
    REDEMPTION.  As stated in the Prospectus, shares of each Class of the Fund
can be redeemed for cash at any time at the net asset value per share next
determined; however, such redemption proceeds will be reduced by the amount of
any applicable CDSC. If shares are held in a shareholder's account without a
share certificate, a written request for redemption to the Fund's Transfer Agent
at P.O. Box 983, Jersey City, NJ 07303 is required. If certificates are held by
the shareholder, the shares may be redeemed by surrendering the certificates
with a written request for redemption. The share certificate, or an accompanying
stock power, and the request for redemption, must be signed by the shareholder
or shareholders exactly as the shares are registered. Each request for
redemption, whether or not accompanied by a share certificate, must be sent to
the Fund's Transfer Agent, which will redeem the shares at their net asset value
next computed (see "Purchase of Fund Shares" in the Prospectus) after it
receives the request, and certificate, if any, in good order. Any redemption
request received after such 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. 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, payment of the
redemption proceeds may be delayed for the minimum time needed to verify that
the check used for investment has been honored (not more than fifteen days from
the time of receipt of the check by the Transfer Agent). Shareholders
maintaining margin accounts with DWR or another selected broker-dealer are
referred to their account executive regarding restrictions on redemption of
shares of the Fund pledged in the margin account.
    
 
                                       29
<PAGE>
   
    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 times shares subject to the charge have been held), any transfer involving
less than all of the shares in an account will be made on a pro rata basis (that
is, by transferring shares in the same proportion that the transferred shares
bear to the total shares in the account immediately prior to the transfer). The
transferred shares will continue to be subject to any applicable CDSC as if they
had not been so transferred.
    
 
   
    REINSTATEMENT PRIVILEGE.  As discussed in the Prospectus, a shareholder who
has had his or her shares redeemed or repurchased and has not previously
exercised this reinstatement privilege may within 35 days after the date of
redemption or repurchase reinstate any portion or all of the proceeds of such
redemption or repurchase in shares of the Fund in the same Class at the net
asset value next determined after a reinstatement request, together with the
proceeds, is received by the Transfer Agent.
    
 
    Exercise of the reinstatement privilege will not affect the federal income
tax treatment of any gain or loss realized upon the redemption or repurchase,
except that if the redemption or repurchase resulted in a loss and reinstatement
is made in shares of the Fund, some or all of the loss, depending on the amount
reinstated, will not be allowed as a deduction for federal income tax purposes,
but will be applied to adjust the cost basis of the shares acquired upon
reinstatement.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
    As discussed in the Prospectus, the Fund will determine either to distribute
or to retain all or part of any net long-term capital gains in any year for
reinvestment. If any such gains are retained, the Fund will pay federal income
tax thereon, and will notify shareholders that, following an election by the
Fund, the shareholders will be required to include such undistributed gains in
determining their taxable income and may claim their share of the tax paid by
the Fund as a credit against their individual federal income tax.
 
    Because the Fund intends to distribute all of its net investment income and
capital gains to shareholders and otherwise continue to qualify as a regulated
investment company under Subchapter M of the Internal Revenue Code, it is not
expected that the Fund will be required to pay any federal income tax.
Shareholders will normally have to pay federal income taxes, and any state
income taxes, on the dividends and distributions they receive from the Fund.
Such dividends and distributions, to the extent that they are derived from net
investment income or net short-term capital gains, are taxable to the
shareholder as ordinary income regardless of whether the shareholder receives
such payments in additional shares or in cash. Any dividends declared in the
last quarter of any calendar year which are paid in the following year prior to
February 1 will be deemed received by the shareholder in the prior calendar
year.
 
    Gains or losses on 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.
 
    Gains or losses on the Fund's transactions, if any, in futures generally are
treated as 60% long-term and 40% short-term capital gains or losses. When the
Fund engages in futures transactions, various tax regulations applicable to the
Fund may have the effect of causing the Fund to recognize a gain or loss for tax
purposes before that gain or loss is realized, or to defer recognition of a
realized loss for tax purposes. Recognition, for tax purposes, of an unrealized
loss may result in a lesser amount of the Fund's realized net gains being
available for distribution.
 
    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.
 
                                       30
<PAGE>
    Any dividend or capital gains distribution received by a shareholder from
any investment company will have the effect of reducing the net asset value of
the shareholder's stock in that company by the exact amount of the dividend or
capital gains distribution. Furthermore, capital gains distributions and
dividends are subject to federal income taxes. If the net asset value of the
shares should be reduced below a shareholder's cost as a result of the payment
of dividends or the distribution of realized net long-term capital gains, such
payment or distribution 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 fully taxable. Therefore, an investor should consider the
tax implications of purchasing Fund shares immediately prior to a dividend or
distribution record date.
 
    Dividend payments will be eligible for the federal dividends received
deduction available to the Fund's corporate shareholders only to the extent the
aggregate dividends received by the Fund would be eligible for the deduction if
the Fund were the shareholder claiming the dividends received deduction. The
amount of dividends paid by the Fund which may qualify for the dividends
received deduction is limited to the aggregate amount of qualifying dividends
which the Fund derives from its portfolio investments which the Fund has held
for a minimum period, usually 46 days. Any distributions made by the Fund will
not be eligible for the dividends received deduction with respect to shares
which are held by the shareholder for 45 days or less. Any long-term capital
gain distributions will also not be eligible for the dividends received
deduction. The ability to take the dividends received deduction will also be
limited in the case of a Fund shareholder which incurs or continues indebtedness
which is directly attributable to its investment in the Fund.
 
    After the end of the year, shareholders will be sent full information on
their dividends and capital gains distributions for tax purposes, including
information as to the portion taxable as ordinary income, the portion taxable as
long-term capital gains and the portion eligible for the dividends received
deduction. 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 indentification numbers must be
furnished and certified as to their accuracy.
 
    Shareholders are urged to consult their attorneys or tax advisers regarding
specific questions as to federal, state or local taxes.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
   
    As discussed in the Prospectus, from time to time the Fund may quote its
"total return" in advertisements and sales literature. These figures are
computed separately for Class A, Class B, Class C and Class D shares. The Fund's
"average annual total return" represents an annualization of the Fund's total
return over a 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 average
annual total returns of the Fund for the fiscal year ended June 30, 1997, for
the five year period ended June 30, 1997 and for the period from December 1,
1987 (commencement of operations) through June 30, 1997, were 19.71%, 16.74% and
15.67%, respectively. These returns are for Class B only; there were no other
Classes of shares outstanding on such date.
    
 
   
    In addition to the foregoing, the Fund may advertise its total return for
each Class over different periods of time by means of aggregate, average,
year-by-year or other types of total return figures. Such calculations may or
may not reflect the imposition of the maximum front-end sales charge for Class A
or the deduction of the CDSC for each of Class B and Class C which, if
reflected, would reduce the performance quoted. For example, the average annual
total returns of the Fund may be calculated in the
    
 
                                       31
<PAGE>
   
manner described above, but without deduction for any applicable sales charge.
Based on this calculation, the average annual total return of the Fund for the
fiscal year ended June 30, 1997, for the five year period ended June 30, 1997
and for the period from December 1, 1987 through June 30, 1997, were 24.71%,
16.96% and 15.67%, respectively. These returns are for Class B only; there were
no other Classes of shares outstanding on such date.
    
 
   
    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 the 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 total return for the fiscal year ended June 30, 1997 was
24.71%, the total return for the five year period ended June 30, 1997 was
118.83%, and the total return for the period from December 1, 1987 through June
30, 1997 was 303.46%. These returns are for Class B only; there were no other
Classes of shares outstanding on such date.
    
 
   
    The Fund may also advertise the growth of hypothetical investments of
$10,000, $50,000 and $100,000 in each Class of shares of the Fund by adding 1 to
the Fund's aggregate total return to date (expressed as a decimal and without
taking into account the effect of any applicable CDSC) and multiplying by
$9,475, $48,000 and $97,000 in the case of Class A (investments of $10,000,
$50,000 and $100,000 adjusted for the initial sales charge) or by $10,000,
$50,000 and $100,000 in the case of each of Class B, Class C and Class D, as the
case may be. Investments of $10,000, $50,000 and $100,000 in the Fund at
inception would have grown to $40,346, $201,730 and $403,460, respectively, at
June 30, 1997. This information is for Class B only; there were no other Classes
of shares outstanding on such date.
    
 
    The Fund from time to time may also advertise its performance relative to
certain performance rankings and indexes compiled by independent organizations.
 
   
DESCRIPTION OF SHARES OF THE FUND
    
- --------------------------------------------------------------------------------
 
   
    The shareholders of the Fund are entitled to a full vote for each full share
held. All of the Trustees have been elected by the shareholders of the Fund,
most recently at Special Meetings of Shareholders held on May 21, 1997. On that
date, Wayne E. Hedien was also elected as a Trustee of the Fund, with his team
to commence on September 1, 1997. The Trustees themselves have the power to
alter the number and the terms of office of the Trustees, and they may at any
time lengthen their own terms or make their terms of unlimited duration and
appoint their own successors, provided that always at least a majority of the
Trustees has been elected by the shareholders of the Fund. Under certain
circumstances the Trustees may be removed by action of the Trustees. The
shareholders also have the right under certain circumstances to remove the
Trustees. The voting rights of shareholders are not cumulative, so that holders
of more than 50 percent of the shares voting can, if they choose, elect all
Trustees being selected, while the holders of the remaining shares would be
unable to elect any Trustees.
    
 
   
    The Declaration of Trust permits the Trustees to authorize the creation of
additional series of shares (the proceeds of which would be invested in
separate, independently managed portfolios) and additional classes of shares
within any series (which would be used to distinguish among the rights of
different categories of shareholders, as might be required by future regulations
or other unforeseen circumstances). The Trustees have not authorized any such
additional series or classes of shares other than as set forth in the
Prospectus.
    
 
    The Declaration of Trust further provides that no Trustee, officer, employee
or agent of the Fund is liable to the Fund or to a shareholder, nor is any
Trustee, officer, employee or agent liable to any third persons in connection
with the affairs of the Fund, except as such liability may arise from his/her or
its own bad faith, willful misfeasance, gross negligence, or reckless disregard
of his/her or its duties. It also
 
                                       32
<PAGE>
provides that all third persons shall look solely to the Fund's property for
satisfaction of claims arising in connection with the affairs of the Fund. With
the exceptions stated, the Declaration of Trust provides that a Trustee,
officer, employee or agent is entitled to be indemnified against all liability
in connection with the affairs of the Fund.
 
    The Fund is authorized to issue an unlimited number of shares of beneficial
interest. The Fund shall be of unlimited duration subject to the provisions in
the Declaration of Trust concerning termination by action of the shareholders.

LEGAL COUNSEL

DEAN WITTER VALUE-ADDED MARKET SERIES -- EQUITY PORTFOLIO
NOTES TO FINANCIAL STATEMENTS JUNE 30, 1997
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter Value-Added Market Series -- Equity Portfolio (the "Fund") is
registered under the Investment Company Act of 1940, amended (the "Act"), as a
diversified, open-end management investment company. The Fund's investment
objective is to achieve a high level of total return on its assets through a
combination of capital appreciation and current income. The Fund seeks to
achieve its objective by investing, on an equally-weighted basis, in a
diversified portfolio of common stocks of the companies which are included in
the Standard & Poor's 500 Composite Stock Price Index. The Fund was organized as
a Massachusetts business trust on May 27, 1987 and commenced operations on
December 1, 1987.
 
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 a security is traded on more than one exchange, the security is
valued on the exchange designated as the primary market pursuant to procedures
adopted by the Trustees); (2) all other portfolio securities for which
over-the-counter market quotations are readily available are valued at the
latest 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 Trustees; and
(4) short-term debt securities having a maturity date of more than sixty days at
time of purchase are valued on a mark-to-market basis until sixty days prior to
maturity and thereafter at amortized cost based on their value on the 61st day.
Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.
 
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 respective life of the securities. Interest
income is accrued daily.

DEAN WITTER VALUE-ADDED MARKET SERIES -- EQUITY PORTFOLIO
NOTES TO FINANCIAL STATEMENTS JUNE 30, 1997, 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 ex-dividend 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 the Investment Manager, the
Fund pays the Investment Manager a management fee, accrued daily and payable
monthly, by applying the following annual rates to the net assets of the Fund
determined as of the close of each business day: 0.50% to the portion of daily
net assets not exceeding $500 million; 0.45% to the portion of daily net assets
exceeding $500 million but not exceeding $1 billion; and 0.425% to the portion
of daily net assets exceeding $1 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 all
personnel, including officers of the Fund who are employees of the Investment
Manager. The Investment Manager also bears the cost of telephone services, heat,
light, power and other utilities provided to the Fund.
 
3. PLAN OF DISTRIBUTION
 
Shares of the Fund are distributed by Dean Witter Distributors Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Fund has adopted a
Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the Act pursuant
to which the Fund pays the Distributor compensation, accrued daily

and payable monthly, at an annual rate of 1.0% of the lesser of: (a) the average
daily aggregate gross sales of the Fund's shares since the Fund's inception (not
including reinvestment of dividend or capital gain distributions) less the
average daily aggregate net asset value of the Fund's shares redeemed since the
Fund's inception upon which a contingent deferred sales charge has been imposed
or upon which such charge has been waived; or (b) the Fund's average daily net
assets. Amounts paid under the Plan are paid to the Distributor to compensate it
for the services provided and the expenses borne by it and others in the
distribution of the Fund's shares, including the payment of commissions for
sales of the Fund's shares and incentive compensation to, and expenses of, the
account executives of Dean Witter Reynolds Inc. ("DWR"), an affiliate of the
Investment Manager and Distributor, and others who engage in or support
distribution of the Fund's 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 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
distribution expenses.
 
Provided that the Plan continues in effect, any cumulative expenses incurred but
not yet recovered may be recovered through future distribution fees from the
Fund and contingent deferred sales charges from the Fund's shareholders.
 
Although there is no legal obligation for the Fund to pay expenses incurred in
excess of payments made to the Distributor under the Plan and the proceeds of
contingent deferred sales charges paid by investors upon redemption of shares,
if for any reason the Plan is terminated, the Trustees will consider at that
time the manner in which to treat such expenses. The Distributor has advised the
Fund that such excess amounts, including carrying charges, total $61,114,557 at
June 30, 1997.
 
The Distributor has informed the Fund that for the year ended June 30, 1997, it
received approximately $1,243,000 in contingent deferred sales charges from
certain redemptions of the Fund's shares.

DEAN WITTER VALUE-ADDED MARKET SERIES -- EQUITY PORTFOLIO
REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND TRUSTEES
OF DEAN WITTER VALUE-ADDED MARKET SERIES -- EQUITY PORTFOLIO
 
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 Value-Added Market
Series -- Equity Portfolio (the "Fund") at June 30, 1997, 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 nine years in the period then ended and for the period December 1, 1987
(commencement of operations) through June 30, 1988, 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 June 30, 1997 by
correspondence with the custodian and brokers and the application of alternative
auditing procedures where confirmations from brokers were not received, provide
a reasonable basis for the opinion expressed above.

Item 27. INDEMNIFICATION.

     Pursuant to Section 5.3 of the Registrant's Declaration of Trust and 
under Section 4.8 of the Registrant's By-Laws, the indemnification of the 
Registrant's trustees, officers, employees and agents is permitted if it is 
determined that they acted under the belief that their actions were in or not 
opposed to the best interest of the Registrant, and, with respect to any 
criminal proceeding, they had reasonable cause to believe their conduct was 
not unlawful.  In addition, indemnification is permitted only if it is 
determined that the actions in question did not render them liable by reason 
of willful misfeasance, bad faith or gross negligence in the performance of 
their duties or by reason of reckless disregard of their obligations and 
duties to the Registrant.  Trustees, officers, employees and agents will be 
indemnified for the expense of litigation if it is determined that they are 
entitled to 


                                          2
<PAGE>

indemnification against any liability established in such litigation.  The 
Registrant may also advance money for these expenses provided that they give 
their undertakings to repay the Registrant unless their conduct is later 
determined to permit indemnification.

    Pursuant to Section 5.2 of the Registrant's Declaration of Trust and 
paragraph 8 of the Registrant's Investment Management Agreement, neither the 
Investment Manager nor any trustee, officer, employee or agent of the 
Registrant shall be liable for any action or failure to act, except in the 
case of bad faith, willful misfeasance, gross negligence or reckless 
disregard of duties to the Registrant.

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

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

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

execution by a majority of the then Trustees of an instrument setting forth such
establishment and designation and the relative rights, preferences, voting
powers, restrictions, limitations as to dividends, qualifications, and terms and
conditions of such class, or as otherwise provided in such instrument, which

between each of the Additional Classes, or (ii) among each of the Existing Class
and the Additional Classes; and be it further

RESOLVED, pursuant to Section 6.9(h) of the Declaration, all shares of the Trust

                               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.

                    DEAN WITTER VALUE-ADDED MARKET SERIES 

                 AMENDED AND RESTATED AS OF OCTOBER 25, 1996

ADVISER", "MAJORITY SHAREHOLDER VOTE", "1940 ACT", "SHAREHOLDER", "SHARES",

                            SHAREHOLDERS' MEETINGS 

   SECTION 3.1. PLACE OF MEETINGS. Meetings of Shareholders shall be held at 
such place, within or without the Commonwealth of Massachusetts, as may be 
designated from time to time by the Trustees. 

   SECTION 3.2. MEETINGS. Meetings of Shareholders of the Trust shall be held 
whenever called by the Trustees or the President of the Trust and whenever 
election of a Trustee or Trustees by Shareholders is required by the 
provisions of Section 16(a) of the 1940 Act, for that purpose. Meetings of 
Shareholders 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, except to the 
extent otherwise required by Section 16(c) of the 1940 Act, as made 
applicable to the Trust by the provisions of Section 2.3 of the Declaration. 
Such request shall state the purpose or purposes of such meeting and the 
matters proposed to be acted on thereat. Except to the extent otherwise 
required by Section 16(c) of the 1940 Act, as made applicable to the Trust by 
the provisions of Section 2.3 of the Declaration, the Secretary shall inform 
such Shareholders of the reasonable estimated cost of preparing and mailing 
such notice of the meeting, and upon payment to the Trust of such costs, the 
Secretary shall give notice stating the purpose or purposes of the meeting to 
all entitled to vote at such meeting. No meeting need be called upon the 
request of the holders of Shares entitled to cast less than a majority of all 
votes entitled to be cast at such meeting, to consider any matter which is 
substantially the same as a matter voted upon at any meeting of Shareholders 
held during the preceding twelve months. 

   SECTION 3.3. NOTICE OF MEETINGS. Written or printed notice of every 
Shareholders' meeting stating the place, date, and purpose or purposes 
thereof, shall be given by the Secretary not less than ten (10) nor more than

such meeting. Such notice shall be deemed to be given when deposited in the 
United States mail, postage prepaid, directed to the Shareholder at his 
address as it appears on the records of the Trust.

   SECTION 3.4. QUORUM AND ADJOURNMENT OF MEETINGS. Except as otherwise 
provided by law, by the Declaration or by these By-Laws, at all meetings of 
Shareholders 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 Shareholders present or represented 
by proxy and entitled to vote thereat shall have power to adjourn the meeting 
from time to time. Any adjourned meeting may be held as adjourned without 
further notice. At any adjourned meeting at which a quorum shall be present, 
any business may be transacted as if the meeting had been held as originally 
called. 

   SECTION 3.5. VOTING RIGHTS, PROXIES. At each meeting of Shareholders, each 
holder of record of Shares entitled to vote thereat shall be entitled to one 
vote in person or by proxy, executed in writing by the Shareholder or his 
duly authorized attorney-in-fact, for each Share of beneficial interest of 
the Trust and for the fractional portion of one vote for each fractional 
Share entitled to vote so registered in his name on the records of the Trust 
on the date fixed as the record date for the determination of Shareholders 
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 
Shareholders, 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. Pursuant to a resolution of a majority of the Trustees, proxies may 
be solicited in the name of one or more Trustees or Officers of the Trust. 

   SECTION 3.6. VOTE REQUIRED. Except as otherwise provided by law, by the 
Declaration of Trust, or by these By-Laws, at each meeting of Shareholders at 
which a quorum is present, all matters shall be decided by Majority 
Shareholder Vote. 

   SECTION 3.7. INSPECTORS OF ELECTION. In advance of any meeting of 
Shareholders, the Trustees may appoint Inspectors of Election to act at the 
meeting or any adjournment thereof. If Inspectors of Election are not so 
appointed, the chairman of any meeting of Shareholders may, and on the 
request of any Shareholder or his proxy shall, appoint Inspectors of Election 
of the meeting. In case any person appointed as Inspector fails to appear or 
fails or refuses to act, the vacancy may be filled by appointment made by the 
Trustees in advance of the convening of the meeting or at the meeting by the 
person acting as chairman. The Inspectors of Election shall determine the 
number of Shares outstanding, the Shares represented at the meeting, the 
existence of a quorum, the authenticity, validity and effect of proxies, 
shall receive votes, ballots or consents, shall hear and determine all 
challenges and questions in any way arising in connection with the right to 
vote, shall count and tabulate all votes or consents, determine the results, 
and do such other acts as may be proper to conduct the election or vote with 
fairness to all Shareholders. On request of the chairman of the meeting, or 
of any Shareholder or his proxy, the Inspectors of Election shall make a 
report in writing of any challenge or question or matter determined by them 
and shall execute a certificate of any facts found by them. 

   SECTION 3.8. INSPECTION OF BOOKS AND RECORDS. Shareholders shall have such 
rights and procedures of inspection of the books and records of the Trust as 
are granted to Shareholders under the Corporations and Associations Law of 
the State of Maryland. 

   SECTION 3.9. ACTION BY SHAREHOLDERS 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 Shareholders may be taken without a meeting if a 
majority of the Shareholders entitled to vote upon the action consent to the 
action in writing and such consents are filed with the records of the Trust. 
Such consent shall be treated for all purposes as a vote taken at a meeting 
of Shareholders. 

   SECTION 3.10. PRESENCE AT MEETINGS. Presence at meetings of shareholders 
requires physical attendance by the shareholder or his or her proxy at the 
meeting site and does not encompass attendance by telephonic or other 
electronic means.

<PAGE> 

                                  ARTICLE IV 

                                   TRUSTEES 

   SECTION 4.1. MEETINGS OF THE TRUSTEES. The Trustees may in their 
discretion provide for regular or special meetings of the Trustees. Regular 
meetings of the Trustees may be held at such time and place as shall be 
determined from time to time by the Trustees without further notice. Special 
meetings of the Trustees may be called at any time by the President and shall 
be called by the President or the Secretary upon the written request of any 
two (2) Trustees. 

   SECTION 4.2. NOTICE OF SPECIAL MEETINGS. Written notice of special 
meetings of the Trustees, stating the place, date and time thereof, shall be 
given not less than two (2) days before such meeting to each Trustee, 
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 Trustee at his address as it appears on the records of the 
Trust. Subject to the provisions of the 1940 Act, notice or waiver of notice 
need not specify the purpose of any special meeting. 

   SECTION 4.3. TELEPHONE MEETINGS. Subject to the provisions of the 1940 
Act, any Trustee, or any member or members of any committee designated by the 
Trustees, may participate in a meeting of the Trustees, 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 4.4. QUORUM, VOTING AND ADJOURNMENT OF MEETINGS. At all meetings 
of the Trustees, a majority of the Trustees 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 Trustees present shall be the act 
of the Trustees, unless the concurrence of a greater proportion is expressly 
required for such action by law, the Declaration or these By-Laws. If at any 
meeting of the Trustees there be less than a quorum present, the Trustees 
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 4.5. ACTION BY TRUSTEES 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 Trustees may be taken without a meeting if a consent in 
writing setting forth the action shall be signed by all of the Trustees 
entitled to vote upon the action and such written consent is filed with the 
minutes of proceedings of the Trustees. 

   SECTION 4.6. EXPENSES AND FEES. Each Trustee may be allowed expenses, if 
any, for attendance at each regular or special meeting of the Trustees, and 
each Trustee who is not an officer or employee of the Trust or of its 
investment manager or underwriter or of any corporate affiliate of any of 
said persons shall receive for services rendered as a Trustee of the Trust 
such compensation as may be fixed by the Trustees. Nothing herein contained 
shall be construed to preclude any Trustee from serving the Trust in any 
other capacity and receiving compensation therefor. 

   SECTION 4.7.  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 Trust and all 
checks, notes, drafts and other obligations for the payment of money by the 
Trust shall be signed, and all transfer of securities standing in the name of 
the Trust shall be executed, by the Chairman, the President, any Vice 
President or the Treasurer or by any one or more officers or agents of the 
Trust as shall be designated for that purpose by vote of the Trustees; 
notwithstanding the above, nothing in this Section 4.7 shall be deemed to 
preclude the electronic authorization, by designated persons, of the Trust's 
Custodian (as described herein in Section 9.1) to transfer assets of the 
Trust, as provided for herein in Section 9.1. 

   SECTION 4.8. INDEMNIFICATION OF TRUSTEES, OFFICERS, EMPLOYEES AND 
AGENTS. (a) The Trust 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 

                                3           

<PAGE>

(other than an action by or in the right of the Trust) by reason of the fact 
that he is or was a Trustee, officer, employee, or agent of the Trust. 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 Trust, and, with respect to any criminal 
action or proceeding, had no reasonable cause to believe his conduct was 
unlawful. 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 Trust, and, with respect to any 
criminal action or proceeding, had reasonable cause to believe that his 
conduct was unlawful. 

   (b) The Trust 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 Trust to obtain a judgment or decree in its 
favor by reason of the fact that he is or was a Trustee, officer, employee, 
or agent of the Trust. The indemnification shall be against expenses, 
including attorneys' 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 interests of the Trust; 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 Trust, 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 
Trust 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 Trustee, officer, employee 
or agent 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 Trustee, officer, employee, or agent of the Trust 
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 
subsections (a) or (b) of this section may be made by the Trust only as 
authorized in the specific case after a determination that indemnification of 
the Trustee, officer, employee, or agent is proper in the circumstances 
because he has met the applicable standard of conduct set forth in 
subsections (a) or (b). 

       (2) The determination shall be made: 

       (i) By the Trustees, by a majority vote of a quorum which consists of 
    Trustees who were not parties to the action, suit or proceeding; or 

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

     (iii) By the Shareholders. 

     (3) Notwithstanding any provision of this Section 4.8, 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 Section 17(h) and (i) of the Investment Company Act of 1940 
    ("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-- 

                                4           

<PAGE>

          (A) a majority of a quorum of Trustees who are neither "interested 
         persons" of the Trust, as defined in Section 2(a)(19) of the 
         Investment Company Act of 1940, 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 Trustee, officer, 
employee or agent of the Trust in defending a civil or criminal action, suit 
or proceeding may be paid by the Trust in advance of the final disposition 
thereof if: 

        (1) authorized in the specific case by the Trustees; and 

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

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

           (ii) the Trust 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 Trustees who are 
             neither "interested persons" of the Trust, as defined in Section 
             2(a)(19) of the 1940 Act, 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 Shareholders or disinterested Trustees 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 Trustee, officer, employee, or agent and inure to the 
benefit of the heirs, executors and administrators of such person; provided 
that no person may satisfy any right of indemnity or reimbursement granted 
herein or to which he may be otherwise entitled except out of the property of 
the Trust, and no Shareholder shall be personally liable with respect to any 
claim for indemnity or reimbursement or otherwise. 

   (g) The Trust may purchase and maintain insurance on behalf of any person 
who is or was a Trustee, officer, employee, or agent of the Trust, 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 Trust 
purchase insurance to indemnify any officer or Trustee against liability for 
any act for which the Trust itself is not permitted to indemnify him. 

   (h) Nothing contained in this Section shall be construed to protect any 
Trustee or officer of the Trust against any liability to the Trust 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. 

                                  ARTICLE V

   SECTION 5.1. EXECUTIVE AND OTHER COMMITTEES. The Trustees, by resolution 
adopted by a majority of the Trustees, may designate an Executive Committee 
and/or committees, each committee to consist of two (2) or more of the 
Trustees of the Trust and may delegate to such committees, in the intervals 
between meetings of the Trustees, any or all of the powers of the Trustees in 
the management of the business and affairs of the Trust. In the absence of 
any member of any such committee, the members thereof present at any meeting, 
whether or not they constitute a quorum, may appoint a Trustee to act in 
place of such absent member. Each such committee shall keep a record of its 
proceedings. 

                                5           

<PAGE>

   The Executive Committee and any other committee shall fix its own rules or 
procedure, but the presence of at least fifty percent (50%) of the members of 
the whole committee shall in each case be necessary to constitute a quorum of 
the committee and the affirmative vote of the majority of the members of the 
committee present at the meeting shall be necessary to take action. 

   All actions of the Executive Committee shall be reported to the Trustees 
at the meeting thereof next succeeding to the taking of such action. 

   SECTION 5.2. ADVISORY COMMITTEE. The Trustees may appoint an advisory 
committee which shall be composed of persons who do not serve the Trust in 
any other capacity and which shall have advisory functions with respect to 
the investments of the Trust but which shall have no power to determine that 
any security or other investment shall be purchased, sold or otherwise 
disposed of by the Trust. The number of persons constituting any such 
advisory committee shall be determined from time to time by the Trustees. 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 Trustees may from time to time determine to be appropriate. 

   SECTION 5.3. COMMITTEE ACTION 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 any Committee of the Trustees appointed pursuant to Section 
5.1 of these By-Laws may be taken without a meeting if a consent in writing 
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. 

                                  ARTICLE VI

such removal shall be without prejudice to the contractual rights, if any, of 
the person so removed.

                         DIVIDENDS AND DISTRIBUTIONS 

   Subject to any applicable provisions of law and the Declaration, dividends 
and distributions upon the Shares may be declared at such intervals as the 
Trustees may determine, in cash, in securities or other property, or in 
Shares, from any sources permitted by law, all as the Trustees shall from 
time to time determine. 

                                7           

<PAGE>

   Inasmuch as the computation of net income and net profits from the sales 
of securities or other properties for federal income tax purposes may vary 
from the computation thereof on the records of the Trust, the Trustees shall 
have power, in their discretion, to distribute as income dividends and as 
capital gain distributions, respectively, amounts sufficient to enable the 
Trust to avoid or reduce liability for federal income taxes. 

                                 ARTICLE VIII 

                            CERTIFICATES OF SHARES 

   SECTION 8.1. CERTIFICATES OF SHARES. Certificates for Shares of each 
series or class of Shares shall be in such form and of such design as the 
Trustees shall approve, subject to the right of the Trustees to change such 
form and design at any time or from time to time, and shall be entered in the 
records of the Trust as they are issued. Each such certificate shall bear a 
distinguishing number; shall exhibit the holder's name and certify the number 
of full Shares owned by such holder; shall be signed by or in the name of the 
Trust by the President, or a Vice President, and countersigned by the 
Secretary or an Assistant Secretary or the Treasurer and an Assistant 
Treasurer of the Trust; shall be sealed with the seal; and shall contain such 
recitals as may be required by law. Where any certificate is signed by a 
Transfer Agent or by a Registrar, the signature of such officers and the seal 
may be facsimile, printed or engraved. The Trust may, at its option, 
determine not to issue a certificate or certificates to evidence Shares owned 
of record by any Shareholder. 

   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 Trust, whether because of 
death, resignation or otherwise, before such certificate or certificates 
shall have been delivered by the Trust, such certificate or certificates 
shall, nevertheless, be adopted by the Trust and be issued and delivered as 
though the person or persons who signed such certificate or certificates or 
whose facsimile signature or signatures shall appear therein had not ceased 
to be such officer or officers of the Trust. 

   No certificate shall be issued for any share until such share is fully 
paid. 

   SECTION 8.2. LOST, STOLEN, DESTROYED AND MUTILATED CERTIFICATES. The 
Trustees may direct a new certificate or certificates to be issued in place 
of any certificate or certificates theretofore issued by the Trust alleged to 
have been lost, stolen or destroyed, upon satisfactory proof of such loss, 
theft, or destruction; and the Trustees may, in their discretion, require the 
owner of the lost, stolen or destroyed certificate, or his legal 
representative, to give to the Trust 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 they may direct, as 
indemnity against any claim that may be against them or any of them on 
account of or in connection with the alleged loss, theft or destruction of 
any such certificate. 

                                  ARTICLE IX 

                                  CUSTODIAN 

   SECTION 9.1. APPOINTMENT AND DUTIES. The Trust shall at times employ a 
bank or trust company having capital, surplus and undivided profits of at 
least five million dollars ($5,000,000) as custodian with authority as its 
agent, but subject to such restrictions, limitations and other requirements, 
if any, as may be contained in these By-Laws and the 1940 Act: 

     (1) to receive and hold the securities owned by the Trust and deliver 
    the same upon written or electronically transmitted order; 

     (2) to receive and receipt for any moneys due to the Trust and deposit 
    the same in its own banking department or elsewhere as the Trustees may 
    direct; 

     (3) to disburse such funds upon orders or vouchers; 

                                8           

<PAGE>

all upon such basis of compensation as may be agreed upon between the 
Trustees and the custodian. If so directed by a Majority Shareholder Vote, 
the custodian shall deliver and pay over all property of the Trust held by it 
as specified in such vote. 

   The Trustees may also authorize the custodian to employ one or more 
sub-custodians from time to time to perform such of the acts and services of 
the custodian and upon such terms and conditions as may be agreed upon 
between the custodian and such sub-custodian and approved by the Trustees. 

   SECTION 9.2. CENTRAL CERTIFICATE SYSTEM.  Subject to such rules, 
regulations and orders as the Commission may adopt, the Trustees may direct 
the custodian to deposit all or any part of the securities owned by the Trust 
in a system for the central handling of securities established by a national 
securities exchange or a national securities association registered with the 
Commission under the Securities Exchange Act of 1934, or such other person as 
may be permitted by the Commission, or otherwise in accordance with the 1940 
Act, pursuant to which system all securities of any particular class or 
series of any issuer deposited within the system are treated as fungible and 
may be transferred or pledged by bookkeeping entry without physical delivery 
of such securities, provided that all such deposits shall be subject to 
withdrawal only upon the order of the Trust. 

                                  ARTICLE X 

                               WAIVER OF NOTICE 

   Whenever any notice of the time, place or purpose of any meeting of 
Shareholders, Trustees, or of any committee is required to be given in 
accordance with law or under the provisions of the Declaration or these 
By-Laws, a waiver thereof in writing, signed by the person or persons 
entitled to such notice and filed with the records of the meeting, whether 
before or after the holding thereof, or actual attendance at the meeting of 
Shareholders, Trustees or committee, as the case may be, in person, shall be 
deemed equivalent to the giving of such notice to such person. 

                                  ARTICLE XI 

                                MISCELLANEOUS

Trust may be kept outside the Commonwealth of Massachusetts at such place or 
places as the Trustees may from time to time determine, except as otherwise 
required by law. 

   SECTION 11.2. RECORD DATE. The Trustees may fix in advance a date as the 
record date for the purpose of determining Shareholders entitled to notice 
of, or to vote at, any meeting of Shareholders, or Shareholders entitled to 
receive payment of any dividend or the allotment of any rights, or in order 
to make a determination of Shareholders for any other proper purpose. Such 
date, in any case, shall be not more than ninety (90) days, and in case of a 
meeting of Shareholders not less than ten (10) days, prior to the date on 
which particular action requiring such determination of Shareholders is to be 
taken. In lieu of fixing a record date the Trustees may provide that the 
transfer books shall be closed for a stated period but not to exceed, in any 
case, twenty (20) days. If the transfer books are closed for the purpose of 
determining Shareholders entitled to notice of a vote at a meeting of 
Shareholders, such books shall be closed for at least ten (10) days 
immediately preceding such meeting. 

   SECTION 11.3. SEAL. The Trustees shall adopt a seal, which shall be in 
such form and shall have such inscription thereon as the Trustees may from 
time to time provide. The seal of the Trust may be affixed to any document, 
and the seal and its attestation may be lithographed, engraved or otherwise 
printed on any document with the same force and effect as if it had been 
imprinted and attested manually in the same manner and with the same effect 
as if done by a Massachusetts business corporation under Massachusetts law. 

   SECTION 11.4. FISCAL YEAR. The fiscal year of the Trust shall end on such 
date as the Trustees may by resolution specify, and the Trustees may by 
resolution change such date for future fiscal years at any time and from time 
to time.

   SECTION 11.5. ORDERS FOR PAYMENT OF MONEY. All orders or instructions for 
the payment of money of the Trust, and all notes or other evidences of 
indebtedness issued in the name of the Trust, shall be signed by such officer

time designate, or as may be specified in or pursuant to the agreement 
between the Trust and the bank or trust company appointed as Custodian of the 
securities and funds of the Trust. 

                                 ARTICLE XII 

                     COMPLIANCE WITH FEDERAL REGULATIONS

compliance with any federal or state statute, rule or regulation with which 
compliance by the Trust is required.

   These By-Laws may be amended, altered, or repealed, or new By-Laws may be 
adopted, (a) by a Majority Shareholder Vote, or (b) by the Trustees; 
provided, however, that no By-Law may be amended, adopted or repealed by the 
Trustees if such amendment, adoption or repeal requires, pursuant to law, the 
Declaration, or these By-Laws, a vote of the Shareholders. The Trustees shall 
in no event adopt By-Laws which are in conflict with the Declaration, and any 
apparent inconsistency shall be construed in favor of the related provisions 
in the Declaration. 

                                 ARTICLE XIV

                        INVESTMENT MANAGEMENT AGREEMENT
 
    AGREEMENT  made as of the  31st day of May, 1997  by and between Dean Witter
Value-Added Market Series, an unincorporated business trust organized under  the
laws  of the Commonwealth of Massachusetts  (hereinafter called the "Fund"), and
Dean Witter InterCapital  Inc., a Delaware  corporation (hereinafter called  the
"Investment Manager"):
 
    WHEREAS,  The  Fund  is  engaged  in  business  as  an  open-end  management
investment company and is registered as such under the Investment Company Act of
1940, as amended (the "Act"); and
 
    WHEREAS, The Investment Manager is registered as an investment adviser under
the Investment Advisers Act of  1940, and engages in  the business of acting  as
investment adviser; and
 
    WHEREAS,  The Fund is  authorized to issue shares  of beneficial interest in
separate portfolios  (the "Portfolios")  with each  such Portfolio  representing
interests in a separate portfolio of securities and other assets; and
 
    WHEREAS, The Fund presently offers shares in one Portfolio designated as the
Equity Portfolio, such Portfolio together with all other Portfolios subsequently
established  by the Fund  with respect to  which the Fund  desires to retain the
Investment Manager to render management and investment advisory services in  the
manner  and on the terms and conditions hereinafter set forth being collectively
referred to as the "Portfolios"; and
 
    WHEREAS, The Investment Manager desires  to be retained to perform  services
on said terms and conditions:
 
    Now, Therefore, this Agreement
 
                              W I T N E S S E T H:
 
that  in  consideration of  the premises  and  the mutual  covenants hereinafter
contained, the Fund and the Investment Manager agree as follows:
 
 
   1.  The Fund  hereby retains  the  Investment Manager  to act  as  investment
manager   of   the   Portfolios  and,  subject  to  the   supervision   of   the
Trustees,  to  supervise  the  investment   activities  of  the  Portfolios   as
hereinafter  set forth.  Without limiting the  generality of  the foregoing, the
Investment Manager  shall  obtain  and  evaluate  such  information  and  advice
relating  to the economy, securities and  commodities markets and securities and
commodities as it deems necessary or  useful to discharge its duties  hereunder;
shall  continuously manage the  assets of the Portfolios  in a manner consistent
with the investment objectives and  policies of the Portfolios; shall  determine
the securities and commodities to be purchased, sold or otherwise disposed of by
the  Portfolios and  the timing of  such purchases, sales  and dispositions; and
shall take  such further  action, including  the placing  of purchase  and  sale
orders  on  behalf  of the  Portfolios,  as  the Investment  Manager  shall deem
necessary or appropriate. The Investment Manager shall also furnish to or  place
at  the disposal of the Fund such  of the information, evaluations, analyses and
opinions formulated or obtained  by the Investment Manager  in the discharge  of
its duties as the Fund may, from time to time, reasonably request.
 
    In  the event  the Fund  establishes one or  more Portfolios  other than the
Equity Portfolio  with respect  to which  it desires  to retain  the  Investment
Manager  to render investment  advisory services hereunder,  it shall notify the
Investment Manager in writing.  If the Investment Manager  is willing to  render
such  services, it  shall notify the  Fund in writing,  whereupon such Portfolio
shall become a Portfolio hereunder.
 
 
   2.  The Investment Manager shall, at its own expense, maintain such staff and
employ  or  retain  such  personnel  and  consult  with such other persons as it
shall from time to time determine to  be necessary or useful to the  performance
of  its obligations under this Agreement. Without limiting the generality of the
foregoing, the staff and personnel of the Investment Manager shall be deemed  to
include  persons employed  or otherwise  retained by  the Investment  Manager to
furnish statistical and  other factual data,  advice regarding economic  factors
and  trends, information with respect  to technical and scientific developments,
and such other information, advice and assistance as the Investment Manager  may
desire. The Investment Manager shall, as agent for the Fund, maintain the Fund's
records and books of account (other than those
<PAGE>
maintained  by  the  Fund's  transfer  agent,  registrar,  custodian  and  other
agencies). All such books and records so maintained shall be the property of the
Fund and, upon request therefor, the  Investment Manager shall surrender to  the
Fund such of the books and records so requested.
 
   3.  The Fund will, from time to time, furnish or otherwise  make available to
the  Investment  Manager  such  financial  reports, proxy  statements  and other
information relating to the business and  affairs of the Fund as the  Investment
Manager  may reasonably require in order to discharge its duties and obligations
hereunder.
 
 
   4.  The Investment Manager shall  bear the cost  of rendering the  investment
management  and  supervisory  services  to  be   performed   by  it  under  this
Agreement, and shall, at its own  expense, pay the compensation of the  officers
and  employees, if any, of  the Fund, and provide  such office space, facilities
and equipment and such clerical help and bookkeeping services as the Fund  shall
reasonably  require in the conduct of its business. The Investment Manager shall
also bear the cost of telephone service, heat, light, power and other  utilities
provided to the Fund.
 
   5.  The Fund assumes and shall  pay or cause to be paid all other expenses of
the  Fund,  including   without   limitation:  fees  pursuant  to  any  plan  of
distribution that the Fund may adopt; the charges and expenses of any registrar,

connection with the registration and maintenance of registration of the Fund and

distributing  prospectuses and statements of  additional information of the Fund

   6.  For the  services  to be  rendered,  the facilities  furnished,  and  the
expenses  assumed   by  the  Investment  Manager, each  Portfolio  of  the  Fund
shall pay to the Investment Manager monthly compensation determined by  applying
an  annual rate or  rates to the  daily net assets  of the respective Portfolios
determined as of the  close of each  business day; the rates  so applied to  the
Equity Portfolio shall be 0.50% of daily net assets up to $500 million; 0.45% of
the next $500 million; and 0.425% of daily net assets over $1 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  net
assets  of the  respective Portfolios  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.
 
                                       2
<PAGE>
    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 a  Portfolio, 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 such  Portfolio 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 in
respect of  such  Portfolio to  the  extent of  such  excess and,  if  required,
pursuant  to any  such laws  or regulations,  will reimburse  such Portfolio for
annual operating  expenses in  excess  of any  expense  limitation that  may  be
applicable;  provided, however, there  shall be excluded  from such expenses the
amount of  any interest,  taxes, brokerage  commissions, distribution  fees  and
extraordinary   expenses  (including  but  not   limited  to  legal  claims  and
liabilities and litigation costs and  any indemnification related thereto)  paid
or  payable by  such Portfolio.  Such reduction, if  any, shall  be computed and
accrued daily, shall be settled on a monthly basis, and shall be based upon  the
expense  limitation  applicable to  such Portfolio  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 Portfolio, such gross income shall  include,
but  not be  limited to,  interest on  debt securities  in the  portfolio of the
Portfolio accrued to and including the last  day of the Fund's fiscal year,  and
dividends  declared on equity securities in  the portfolio of the Portfolio, the
record dates for which fall on or prior to the last day of such fiscal year, but
shall not include gains from the sale of securities.
 
 
   8.  The Investment Manager will use its  best efforts in the supervision  and
management  of  the  investment  activities  of  the  Fund,  but in  the absence
of willful misfeasance, bad faith, gross negligence or reckless disregard of its
obligations hereunder, the Investment Manager shall not be liable to the Fund or
any of its investors for any error of judgment or mistake of law or for any  act
or omission by the Investment Manager or for any losses sustained by the Fund or
its investors.
 
 
   9.  Nothing  contained in this Agreement shall prevent the Investment Manager
or  any   affiliated  person   of   the   Investment   Manager  from  acting  as
investment  adviser or  manager for  any other  person, firm  or corporation and
shall not  in any  way  bind or  restrict the  Investment  Manager or  any  such
affiliated  person from buying, selling or trading any securities or commodities
for their own accounts or for the account of others for whom they may be acting.
Nothing in this  Agreement shall  limit or restrict  the right  of any  Trustee,
officer or employee of the Investment Manager to engage in any other business or
to  devote his  or her  time and attention  in part  to the  management or other
aspects of any other business whether of a similar or dissimilar nature.
 
 
  10.  This Agreement shall remain in effect until April 30, 1999 and from  year
to   year   thereafter   with   respect   to   each   Portfolio   provided  such
continuance with respect  to a Portfolio  is approved at  least annually by  the
vote  of holders of a majority (as defined in the Act) of the outstanding voting
securities of such Portfolio or  by the Trustees of  the Fund; provided that  in
either  event  such continuance  is  also approved  annually  by the  vote  of a
majority of the Trustees of  the Fund who are not  parties to this Agreement  or
"interested  persons" (as defined in the Act) of any such party, which vote must
be cast  in person  at  a meeting  called  for the  purpose  of voting  on  such
approval;  provided, however, that (a) the Fund may, at any time and without the
payment of  any penalty,  terminate  this Agreement  upon thirty  days'  written
notice to the Investment Manager, either by majority vote of the Trustees of the
Fund  or,  with  respect to  a  Portfolio, by  the  vote  of a  majority  of the
outstanding voting  securities  of  such Portfolio;  (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
 
                                       3
<PAGE>
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.
 
    Any  approval  of  this  Agreement  by the  holders  of  a  majority  of the
outstanding voting securities of  any Portfolio shall  be effective to  continue
this  Agreement with  respect to  such Portfolio  notwithstanding (a)  that this
Agreement has not been approved by the holders of a majority of the  outstanding
voting securities of any other Portfolio or (b) that this Agreement has not been
approved  by the vote of a majority  of the outstanding voting securities of the
Fund, unless such  approval shall  be required by  any other  applicable law  or
otherwise.
 
 
  11.  This  Agreement may be amended by the parties without the vote or consent
of the  shareholders of  the  Fund  to  supply  any  omission, to cure,  correct
or  supplement any ambiguous, defective or  inconsistent provision hereof, or if
they deem  it  necessary  to  conform this  Agreement  to  the  requirements  of
applicable  federal laws or regulations, but neither the Fund nor the Investment
Manager shall be liable for failing to do so.
 
 
  12.  This Agreement shall  be construed  in accordance  with the  laws of  the
State  of  New York  and  the  applicable  provisions  of the Act. To the extent
the  applicable law of the  State of New York, or  any of the provisions herein,
conflicts with the applicable provisions of the Act, the latter shall control.
 
 
  13.  The Investment  Manager and  the  Fund each  agree  that the  name  "Dean
Witter,"  which  comprises  a  component  of  the  Fund's  name, is  a  property
right of Dean Witter Reynolds Inc. The Fund agrees and consents that (i) it will
only use the  name "Dean Witter"  as a component  of its name  and for no  other
purpose,  (ii) it will not purport to grant  to any third party the right to use
the name "Dean  Witter" for  any purpose, (iii)  the Investment  Manager or  its
parent,  Morgan Stanley, Dean Witter, 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,  Trustees and shareholders  to take  any and all
actions which the  Investment Manager or  its parent may  request to effect  the
foregoing  and to reconvey to  the Investment Manager or  its parent any and all
rights to such name.
 
 
  14.  The Declaration  of Trust  establishing  Dean Witter  Value-Added  Market
Series, dated  May 27, 1987,  a  copy  of  which,  together  with all amendments
thereto  (the "Declaration"), is on  file in the office  of the Secretary of the
Commonwealth of Massachusetts,  provides that the  name Dean Witter  Value-Added
Market  Series  refers to  the Trustees  under  the Declaration  collectively as
Trustees, but not  as individuals  or personally; and  no Trustee,  shareholder,

property  for  the satisfaction  of  any obligation  or  claim or  otherwise, in
connection with the affairs of said  Dean Witter Value-Added Market Series,  but
the Trust Estate only shall be liable.

                             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.

       AMENDED AND RESTATED PLAN OF DISTRIBUTION PURSUANT TO RULE 12B-1 
                                      OF 
                    DEAN WITTER VALUE-ADDED MARKET SERIES 

   WHEREAS, Dean Witter Value-Added Market Series (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, on April 14, 1994, the Fund most recently amended and restated a 
Plan of Distribution pursuant to Rule 12b-1 under the Act which had initially 
been adopted on October 6, 1987, and the Trustees then determined that there 
was a reasonable likelihood that adoption of the Plan of Distribution, as 
then amended and restated, would benefit the Fund and its shareholders; and 

   WHEREAS, the Trustees believe that continuation of said Plan of 
Distribution, as amended and restated herein, is reasonably likely to 
continue to benefit the Fund and its shareholders; and 

   WHEREAS, on October 6, 1987, the Fund and Dean Witter Reynolds Inc. 
("DWR") entered into a Distribution Agreement pursuant to which the Fund 
employed DWR as distributor of the Fund's shares; and 

   WHEREAS, on January 4, 1993, the Fund and DWR substituted Dean Witter 
Distributors Inc. (the "Distributor") in the place of DWR as distributor of 
the Fund's shares; and 

   WHEREAS, the Fund, DWR and the Distributor intend that DWR will continue 
to promote the sale of Fund shares and provide personal services to Fund 
shareholders with respect to their holdings of Fund shares; and 

   WHEREAS, the Fund and the Distributor entered into a separate Distribution 
Agreement dated as of July 28, 1997 (which superseded a Distribution 
Agreement dated May 31, 1997, which Agreement in turn superseded an Agreement 
dated June 30, 1993), 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 amends the Plan of Distribution previously 
adopted and amended and restated, and the Distributor hereby agrees to the 
terms of said Plan of Distribution (the "Plan"), as amended herein, 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 Trustees determine to 
reimburse as hereinafter set forth. 

   1(a)(ii). The Fund is hereby authorized to reimburse the Distributor, 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 1.0%, 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 Trustees, including a majority of 
the Trustees 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 Trustees 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 

                                1           
<PAGE>
such expenses. The Trustees 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(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 
the lesser of (i) 1.0% per annum of the average daily aggregate sales of the 
Fund's Class B shares since the Fund's inception (not including reinvestment 
of dividends and capital gains distributions from the Fund) less the average 
daily aggregate net asset value of the Fund's Class B shares redeemed since 
the Fund's inception upon which a contingent deferred sales charge has been 
imposed or upon which such charge has been waived, or (ii) 1.0% 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 Trustees 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, including 
personal services to shareholders with respect to holdings of such shares, of 
an investment company whose assets are acquired by the Fund in a tax-free 
reorganization. It is contemplated that, with respect to 

                                2           
<PAGE>
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 and 
Class C shares, payments at the annual rate of 0.25% will be so 
characterized. 

   3. This Plan, as amended and restated, 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 Trustees of the Fund and 
of the Trustees 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 Trustees"), 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 Trustees of the Fund and the 
Trustees 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 Trustees shall request the Distributor to specify such items of 
expenses as the Trustees deem appropriate. The Trustees 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 Trustees, or by vote of a majority of the 
outstanding voting securities of the Fund. The Plan 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 Trustees 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 Trustees 
who are not interested persons (as defined in the Act) of the Fund shall be 
committed to the discretion of the Trustees 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. 

   10. The Declaration of Trust establishing Dean Witter Value-Added Market 
Series, dated May 27, 1987, a copy of which, together with all amendments 
thereto (the "Declaration"), is on file in the office of the Secretary of the 
Commonwealth of Massachusetts, provides that the name Dean Witter Value-Added 
Market Series refers to the Trustees under the Declaration collectively as 
Trustees but not as individuals or personally; and no Trustee, shareholder, 
officer, employee or agent of Dean Witter Value-Added Market Series shall be 
held to any personal liability, nor shall resort be had to their private 
property for this satisfaction of any obligation or claim or otherwise, in 
connection with the affairs of said Dean Witter Value-Added Market Series, 
but the Trust Estate only shall be liable.

                               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.
