- ----------------------------------------------------------------------------------------------------------------------
Management        The Investment Manager receives a monthly fee at the annual rate of 0.55% of average daily net
Fee               assets, scaled down on assets over $500 million. The fee should not be compared with fees paid by
                  other investment companies without also considering applicable sales loads and distribution fees,
                  including those noted below.
- ----------------------------------------------------------------------------------------------------------------------
Distributor       Dean Witter Distributors Inc. (the "Distributor"). The Fund has adopted a distribution plan pursuant

                  equal to 0.20% of the average daily net assets of Class B and 0.25% of the average daily net assets
                  of Class C are currently each characterized as a service fee within the meaning of the National
                  Association of Securities Dealers, Inc. guidelines. The remaining portion of the 12b-1 fee, if any,
                  is characterized as an asset-based sales charge (see pages 14 and 22).
- ----------------------------------------------------------------------------------------------------------------------

                  purchases. Investments of $1 million or more (and investments by certain other limited categories of
                  investors) are not subject to any sales charge at the time of purchase but a contingent deferred
                  sales charge ("CDSC") of 1.0% may be imposed on redemptions within one year of purchase. The Fund is
                  authorized to reimburse the Distributor for specific expenses incurred in promoting the distribution
                  of the Fund's Class A shares and servicing shareholder

                  accounts pursuant to the Fund's 12b-1 Plan. Reimbursement may in no event exceed an amount equal to
                  payments at an annual rate of 0.25% of average daily net assets of the Class (see pages 14, 17 and
                  22).
 
                  - 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. Class B shares are also subject to a 12b-1 fee
                  assessed at the annual rate of 0.75% of the lesser of: (a) the average daily net sales of the Fund's
                  Class B shares or (b) the average daily net assets of Class B. All shares of the Fund held prior to
                  July 28, 1997 have been designated Class B shares. Shares held before May 1, 1997 will convert to
                  Class A shares in May, 2007. In all other instances, Class B shares convert to Class A shares
                  approximately ten years after the date of the original purchase (see pages 14, 19 and 22).
 
                  - Class C shares are offered without a front-end sales charge, but will in most cases be subject to
                  a CDSC of 1.0% if redeemed within one year after purchase. The Fund is authorized to reimburse the
                  Distributor for specific expenses incurred in promoting the distribution of the Fund's Class C
                  shares and servicing shareholder accounts pursuant to the Fund's 12b-1 Plan. Reimbursement may in no
                  event exceed an amount equal to payments at an annual rate of 0.75% of average daily net assets of
                  the Class (see pages 14, 21 and 22).
 
                  - Class D shares are offered only to investors meeting an initial investment minimum of $5 million
                  and to certain other limited categories of investors. Class D shares are offered without a front-end
                  sales charge or CDSC and are not subject to any 12b-1 fee (see pages 14, 21 and 22).
- ----------------------------------------------------------------------------------------------------------------------
Dividends         Dividends from net investment income, are declared daily and paid monthly; capital gains, if any,
and               may be distributed at least annually or retained for reinvestment by the Fund. Dividends and capital
Capital Gains     gains distributions paid on shares of a Class are automatically reinvested in additional shares of
Distributions     the same Class at net asset value unless the shareholder elects to receive cash. Shares acquired by
                  dividend and distribution reinvestment will not be subject to any sales charge or CDSC (see pages 27
                  and 22).
- ----------------------------------------------------------------------------------------------------------------------
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).
- ----------------------------------------------------------------------------------------------------------------------
Risks             The value of the Fund's portfolio securities, and therefore the Fund's net asset value per share,
                  may increase or decrease due to various factors, principally changes in prevailing interest rates
                  and the ability of the issuers of the Fund's portfolio securities to pay interest and principal on
                  such obligations. The Fund also may invest in futures and options which may be considered
                  speculative in nature and may involve greater risks than those customarily assumed by certain other
                  investment companies which do not invest in such instruments. Since the Fund concentrates its
                  investments in California tax-exempt securities, the Fund is affected by any political, economic or
                  regulatory developments affecting the ability of California issuers to pay interest or repay
                  principal (see pages 9-13).

(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").

    THEREAFTER.
    
 
   
(4) ONLY APPLICABLE TO REDEMPTIONS MADE WITHIN ONE YEAR AFTER PURCHASE (SEE
    "PURCHASE OF FUND SHARES-- LEVEL LOAD ALTERNATIVE--CLASS C SHARES").
    
 
   
(5) THE 12B-1 FEE IS ACCRUED DAILY AND PAYABLE MONTHLY. THE ENTIRE 12B-1 FEE
    PAYABLE BY CLASS A AND A PORTION OF THE 12B-1 FEE PAYABLE BY EACH OF CLASS B
    AND CLASS C EQUAL TO 0.20% OF THE AVERAGE DAILY NET ASSETS OF CLASS B AND
    0.25% OF THE AVERAGE DAILY NET ASSETS OF CLASS C ARE CURRENTLY EACH
    CHARACTERIZED AS A SERVICE FEE WITHIN THE MEANING OF NATIONAL ASSOCIATION OF
    SECURITIES DEALERS, INC. ("NASD") GUIDELINES AND ARE PAYMENTS MADE FOR
    PERSONAL SERVICE AND/OR MAINTENANCE OF SHAREHOLDER ACCOUNTS. THE REMAINDER
    OF THE 12B-1 FEE, IF ANY, IS AN ASSET-BASED SALES CHARGE, AND IS A
    DISTRIBUTION FEE PAID TO THE DISTRIBUTOR TO COMPENSATE IT FOR THE SERVICES
    PROVIDED AND THE EXPENSES BORNE BY THE DISTRIBUTOR AND OTHERS IN THE
    DISTRIBUTION OF THE FUND'S SHARES (SEE "PURCHASE OF FUND SHARES--PLAN OF
    DISTRIBUTION").
    
 
   
(6) UPON CONVERSION OF CLASS B SHARES TO CLASS A SHARES, SUCH SHARES WILL BE
    SUBJECT TO THE LOWER 12B-1 FEE APPLICABLE TO CLASS A SHARES. NO SALES CHARGE
    IS IMPOSED AT THE TIME OF CONVERSION OF CLASS B SHARES TO CLASS A SHARES.
    CLASS C SHARES DO NOT HAVE A CONVERSION FEATURE AND, THEREFORE, ARE SUBJECT
    TO AN ONGOING 0.75% 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 California Tax-Free Income Fund (the "Fund") is an open-end,
diversified management investment company. The Fund is a trust of the type
commonly known as a "Massachusetts business trust" and was organized under the
laws of Massachusetts on April 9, 1984.
 
   
    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 a total of 100 investment companies, thirty of
which are listed on the New York Stock Exchange, with combined total assets
including this Fund 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 0.55% of the portion of the daily net assets of the Fund not exceeding $500
million, scaled down at various asset levels to 0.475% on the portion of the
Fund's assets exceeding $1 billion. For the fiscal year ended December 31, 1996,
the Fund accrued total compensation to the Investment Manager amounting to 0.53%
of the Fund's average daily net assets and the Fund's total expenses amounted to
1.32% of the Fund's average daily net assets.
 
INVESTMENT OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------
 
    The investment objective of the Fund is to provide a high level of current
income which is exempt from both federal and California income tax, consistent
with the preservation of capital. There is no assurance that this objective will
be achieved. The Fund seeks to achieve its investment objective by investing its
assets in accordance with the following policies:
 
   1. As a fundamental policy the Fund must have at least 80% of its total
assets invested in California tax-exempt securities, except as stated in
paragraph (3) below. California tax-exempt securities consist of California
Municipal Bonds and California Municipal Notes ("California Municipal
Obligations") and California Municipal Commercial Paper. Only California
tax-exempt securities which satisfy the following standards may be purchased by
the Fund: (a) California Municipal Bonds which are rated at the time of purchase
within the four highest grades by Moody's Investors Service, Inc. ("Moody's") or
Standard & Poor's Corporation ("S&P"); (b) California Municipal Notes of issuers
which at the time of purchase are rated in the two highest grades by Moody's or
S&P, or, if not rated, have outstanding one or more issues of California
Municipal Bonds rated as set forth in clause (a) of this paragraph; (c)
California Municipal Commercial
 
                                       7
<PAGE>
Paper which at the time of purchase is rated P-1 by Moody's or A-1 by S&P; and
(d) unrated securities which at the time of purchase are judged by the
Investment Manager to be of comparable quality to the securities described
above.
 
   
   2. In accordance with the current position of the staff of the Securities and
Exchange Commission, tax-exempt securities which are subject to the federal
alternative minimum tax for individual shareholders ("AMT") will not be included
in the 80% total described in paragraph 1 above. (See "Dividends, Distributions
and Taxes") As such, the remaining portion of the Fund's total assets may be
invested in tax-exempt securities subject to the AMT.
    
 
   3. Up to 20% of the Fund's total assets may be invested in taxable money
market instruments, non-California tax-exempt securities, futures and options
and tax-exempt securities subject to the AMT. However, the Fund may temporarily
invest more than 20% of its total assets in taxable money market instruments and
non-California tax exempt securities, or in tax-exempt securities subject to the
federal alternative minimum tax for individual shareholders, to maintain a
"defensive" posture when, in the opinion of the Investment Manager, it is
advisable to do so because of market conditions. Only those non-California
tax-exempt securities which satisfy the standards set forth in paragraph (1) for
California tax-exempt securities may be purchased by the Fund. The types of
taxable money market instruments in which the Fund may invest are limited to the
following short-term fixed-income securities (maturing in one year or less from
the time of purchase): (i) obligations of the United States Government, its
agencies, instrumentalities or authorities; (ii) commercial paper rated P-1 by
Moody's or A-1 by S&P; (iii) certificates of deposit of domestic banks with
assets of $1 billion or more; and (iv) repurchase agreements with respect to
portfolio securities.
 
    Municipal Obligations are debt obligations of a state, its cities,
municipalities and municipal agencies which generally have maturities, at the
time of their issuance, of either one year or more (Bonds) or from six months to
three years (Notes). Municipal Commercial Paper are short-term obligations of
municipalities. Any Municipal Bond or Municipal Note which depends directly or
indirectly on the credit of the Federal Government, its agencies or
instrumentalities shall be considered to have a rating of Aaa/AAA. An obligation
shall be considered a California Municipal Obligation or California Municipal
Commercial Paper only if, in the opinion of bond counsel, the interest payable
thereon is exempt from both federal income tax and California personal income
tax. The Fund may purchase Municipal Obligations which had originally been
issued by the same issuer as two separate series of the same issue with
different interest rates, but which are now linked together to form one series.
 
    The foregoing percentage and rating policies apply at the time of
acquisition of a security based upon the last previous determination of the
Fund's net asset value. Any subsequent change in any rating or change in
percentages resulting from market fluctuations or other changes in the Fund's
total assets will not require elimination of any security from the Fund's
portfolio until such time as the value of all such securities exceeds 5% of the
Fund's total assets and, at such time, only when the Investment Manager
determines that it is practicable to sell the security without undue market or
tax consequences to the Fund. As such, the Fund may hold Municipal Bonds rated
below investment grade by Moody's and/or S&P in its portfolio. Municipal Bonds
rated below investment grade may not currently be paying any interest and may
have extremely poor prospects of ever attaining any real investment standing.
 
    The two principal classifications of Municipal Obligations and Commercial
Paper are "general obligation" and "revenue" bonds, notes or commercial paper.
General obligation bonds, notes or commercial paper are secured by the issuer's
pledge of its faith, credit and taxing power for the payment of principal and
interest. Issuers of general obligation bonds, notes or commercial paper include
a state, its counties, cities, towns and other governmental units. Revenue
bonds, notes or commercial paper are payable from the revenues derived from a
particular facility or class of facilities or, in some cases, from specific
revenue sources.
 
                                       8
<PAGE>
Revenue bonds, notes or commercial paper are issued for a wide variety of
purposes, including the financing of electric, gas, water and sewer systems and
other public utilities; industrial development and pollution control facilities;
single and multi-family housing units; public buildings and facilities; air and
marine ports, transportation facilities such as toll roads, bridges and tunnels;
and health and educational facilities such as hospitals and dormitories. They
rely primarily on user fees to pay debt service, although the principal revenue
source is often supplemented by additional security features which are intended
to enhance the creditworthiness of the issuer's obligations. In some cases,
particularly revenue bonds issued to finance housing and public buildings, a
direct or implied "moral obligation" of a governmental unit may be pledged to
the payment of debt service. In other cases, a special tax or other charge may
augment user fees.
 
RISK CONSIDERATIONS
 
    Investments in municipal bonds rated either BBB by S&P or Baa by Moody's
(investment grade bonds--the lowest-rated permissible investments by the Fund)
may have speculative characteristics and, therefore, changes in economic
conditions or other circumstances are more likely to weaken their capacity to
make principal and interest payments than would be the case with investments in
securities with higher credit ratings.
 
    Included within the revenue bonds category of bonds described above are
participations in lease obligations or installment purchase contracts
(hereinafter collectively called "lease obligations") of municipalities. State
and local governments issue lease obligations to acquire equipment and
facilities.
 
    Lease obligations may have risks not normally associated with general
obligation or other revenue bonds. Leases and installment purchase or
conditional sale contracts (which may provide for title to the leased asset to
pass eventually to the issuer) have developed as a means for governmental
issuers to acquire property and equipment without the necessity of complying
with the constitutional and statutory requirements generally applicable for the
issuance of debt. Certain lease obligations contain "non-appropriation" clauses
that provide that the governmental issuer has no obligation to make future
payments under the lease or contract unless money is appropriated for such
purpose by the appropriate legislative body on an annual or other periodic
basis. Consequently, continued lease payments on those lease obligations
containing "non-appropriation" clauses are dependent on future legislative
actions. If such legislative actions do not occur, the holders of the lease
obligation may experience difficulty in exercising their rights, including
disposition of the property.
 
    Lease obligations represent a type of financing that may not have the depth
of marketability associated with more conventional municipal obligations, and,
as a result, certain of such lease obligations may be considered illiquid
securities. To determine whether or not the Fund will consider such securities
to be illiquid (the Fund may not invest more than ten percent of its net assets
in illiquid securities), the Trustees of the Fund have established guidelines to
be utilized by the Fund in determining the liquidity of a lease obligation. The
factors to be considered in making the determination include: 1) the frequency
of trades and quoted prices for the obligation; 2) the number of dealers willing
to purchase or sell the security and the number of other potential purchasers;
3) the willingness of dealers to undertake to make a market in the security; and
4) the nature of the marketplace trades, including, the time needed to dispose
of the security, the method of soliciting offers, and the mechanics of the
transfer.
 
    The Fund does not generally intend to invest more than 25% of its total
assets in securities of any one governmental unit. The Fund may invest more than
25% of its total assets in industrial development and pollution control bonds
(two kinds of tax-exempt Municipal Bonds) whether or not the users of facilities
financed by such bonds are in the same industry. In cases where such users are
in the same industry, there may be additional risk to the Fund in the event of
an economic downturn in such industry, which may result generally in a lowered
need for such facilities and a lowered ability of such users to pay for the use
of such facilities.
 
                                       9
<PAGE>
    The value of the Fund's portfolio securities, and therefore the Fund's net
asset value per share, may increase or decrease due to various factors,
principally changes in prevailing interest rates and the ability of the issuers
of the Fund's portfolio securities to pay interest and principal on such
obligations. Generally, a rise in interest rates will result in a decrease in
the Fund's net asset value per share, while a drop in interest rates will result
in an increase in the Fund's net asset value per share.
 
    VARIABLE RATE OBLIGATIONS.  The interest rates payable on certain securities
in which the Fund may invest are not fixed and may fluctuate based upon changes
in market rates. Obligations of this type are called "variable rate"
obligations. The interest rate payable on a variable rate obligation is adjusted
either at predesignated periodic intervals or whenever there is a change in the
market rate of interest on which the interest rate payable is based.
 
    WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS.  From
time to time, in the ordinary course of business, the Fund may purchase
securities on a when-issued or delayed delivery basis or may purchase or sell
securities on a forward commitment basis. When such transactions are negotiated,
the price is fixed at the time of the commitment, but delivery and payment can
take place a month or more after the date of the commitment. There is no overall
limit on the percentage of the Fund's assets which may be committed to the
purchase of securities on a when-issued, delayed delivery or forward commitment
basis. An increase in the percentage of the Fund's assets committed to the
purchase of securities on a when-issued, delayed delivery or forward commitment
basis may increase the volatility of the Fund's net asset value.
 
    ZERO COUPON SECURITIES.  A portion of the fixed-income securities purchased
by the Fund may be zero coupon securities. Such securities are purchased at a
discount from their face amount, giving the purchaser the right to receive their
full value at maturity. The interest earned on such securities is, implicitly,
automatically compounded and paid out at maturity. While such compounding at a
constant rate eliminates the risk of receiving lower yields upon reinvestment of
interest if prevailing interest rates decline, the owner of a zero coupon
security will be unable to participate in higher yields upon reinvestment of
interest received on interest-paying securities if prevailing interest rates
rise.
 
    A zero coupon security pays no interest to its holder during its life.
Therefore, to the extent the Fund invests in zero coupon securities, it will not
receive current cash available for distribution to shareholders. In addition,
zero coupon securities are subject to substantially greater price fluctuations
during periods of changing prevailing interest rates than are comparable
securities which pay interest on a current basis. Current federal tax law
requires that a holder (such as the Fund) of a zero coupon security accrue a
portion of the discount at which the security was purchased as income each year
even though the Fund receives no interest payments in cash on the security
during the year.
 
    The Fund may enter into financial futures contracts, options on such futures
and municipal bond index futures contracts for hedging purposes.
 
    FINANCIAL FUTURES CONTRACTS AND OPTIONS ON FUTURES.  The Fund may invest in
financial futures contracts and related options thereon. The Fund may sell a
financial futures contract or purchase a put option on such futures contract, if
the Investment Manager anticipates interest rates to rise, as a hedge against a
decrease in the value of the Fund's portfolio securities. If the Investment
Manager anticipates that interest rates will decline, the Fund may purchase a
financial futures contract or a call option thereon to protect against an
increase in the price of the securities the Fund intends to purchase. These
futures contracts and related options thereon will be used only as a hedge
against anticipated interest rate changes. A futures contract sale creates an
obligation by the Fund, as seller, to deliver the specific type of instrument
called for in the contract at a specified future time for a specified price. A
futures contract purchase would create an obligation by the Fund, as purchaser,
to take delivery of the specific type of financial instrument at a specified
future time at a specified price. The specific securities delivered or taken,
respectively, at settlement date, would not
 
                                       10
<PAGE>
be determined until or near that date. The determination would be in accordance
with the rules of the exchange on which the futures contract sale or purchase
was effected.
 
    Although the terms of financial futures contracts specify actual delivery or
receipt of securities, in most instances the contracts are closed out before the
settlement date without the making or taking of delivery of the securities.
Closing out of a futures contract is effected by entering into an offsetting
purchase or sale transaction.
 
    Unlike a financial futures contract, which requires the parties to buy and
sell a security on a set date, an option on such a futures contract entitles its
holder to decide on or before a future date whether to enter into such a
contract (a long position in the case of a call option and a short position in
the case of a put option). If the holder decides not to enter into the contract,
the premium paid for the option on the contract is lost. Since the value of the
option is fixed at the point of sale, there are no daily payments of cash to
reflect the change in the value of the underlying contract as there is by a
purchaser or seller of a futures contract. The value of the option does change
and is reflected in the net asset value of the Fund.
 
    A risk in employing futures contracts to protect against the price
volatility of portfolio securities is that the prices of securities subject to
such futures contracts may correlate imperfectly with the behavior of the cash
prices of the Fund's portfolio securities. The risk of imperfect correlation
will be increased by the fact that the financial futures contracts in which the
Fund may invest are on taxable securities rather than tax-exempt securities, and
there is no guarantee that the prices of taxable securities will move in a
similar manner to the prices of tax-exempt securities. The correlation may be
distorted by the fact that the futures market is dominated by short-term traders
seeking to profit from the difference between a contract or security price
objective and their cost of borrowed funds. Such distortions are generally minor
and would diminish as the contract approached maturity.
 
    Another risk is that the Fund's manager could be incorrect in its
expectations as to the direction or extent of various interest rate movements or
the time span within which the movements take place. For example, if the Fund
sold financial futures contracts for the sale of securities in anticipation of
an increase in interest rates, and then interest rates went down instead,
causing bond prices to rise, the Fund would lose money on the sale.
 
    In addition to the risks that apply to all options transactions (see the
Statement of Additional Information for a description of the characteristics of,
and the risks of investing in, options on debt securities), there are several
special risks relating to options on futures. In particular, the ability to
establish and close out positions on such options will be subject to the
development and maintenance of a liquid secondary market. It is not certain that
this market will develop or be maintained.
 
    MUNICIPAL BOND INDEX FUTURES.  The Fund may utilize municipal bond index
futures contracts and options thereon for hedging purposes. The Fund's
strategies in employing such contracts will be similar to that discussed above
with respect to financial futures and options thereon. A municipal bond index is
a method of reflecting in a single number the market value of many different
municipal bonds and is designed to be representative of the municipal bond
market generally. The index fluctuates in response to changes in the market
values of the bonds included within the index. Unlike futures contracts on
particular financial instruments, transactions in futures on a municipal bond
index will be settled in cash, if held until the close of trading in the
contract. However, like any other futures contract, a position in the contract
may be closed out by a purchase or sale of an offsetting contract for the same
delivery month prior to expiration of the contract.
 
    The Fund may not enter into futures contracts or related options thereon if
immediately thereafter the amount committed to margin plus the amount paid for
option premiums exceeds 5% of the value of the Fund's total assets. The Fund may
not purchase or sell futures contracts or related options if
 
                                       11
<PAGE>
immediately thereafter more than one-third of its net assets would be hedged.
 
RISK CONSIDERATIONS RELATING TO CALIFORNIA
 TAX-EXEMPT SECURITIES
 
    The Fund will be affected by any political, economic or regulatory
developments affecting the ability of California issuers to pay interest or
repay principal on their obligations. Various subsequent developments regarding
the California Constitution and State of California ("State") statutes which
limit the taxing and spending authority of California governmental entities may
impair the ability of California issuers to maintain debt service on their
obligations. Of particular impact are constitutional voter initiatives, which
have become common in recent years. The following information constitutes only a
brief summary and is not intended as a complete description.
 
    California is the most populous state in the nation with a total population
at the 1990 census of 29,976,000. Growth has been incessant since World War II,
with population gains in each decade since 1950 of between 18% and 49%. During
the last decade, the population rose 20%. The State now comprises 12.3% of the
nation's population and 12.9% of its total personal income. Its economy is broad
and diversified with major concentrations in high technology research and
manufacturing, aerospace and defense-related manufacturing, trade, real estate,
and financial services. After experiencing strong growth throughout much of the
1980s, the State was adversely affected by both the national recession and the
cutbacks in aerospace and defense spending which had a severe impact on the
economy in Southern California. Although California is still experiencing some
of the effects of the recession and its unemployment is above the national
average, the gap is narrowing and is projected to close to within 1% of the
national average in 1997. California's economic recovery from the recession is
continuing at a strong pace. Recent economic reports indicate that, while the
rate of economic growth in California is expected to moderate over the next
three years, the increases in employment and income will likely exceed those of
the nation as a whole by a significant margin.
 
    These economic difficulties have exacerbated the structural budget imbalance
which has been evident since fiscal year 1985-1986. Since that time, budget
shortfalls have become increasingly more difficult to solve and the State has
recorded in its general fund (the "General Fund") operating deficits in several
fiscal years. Many of these problems have been attributable to the fact that the
great population influx has produced increased demand for education and social
services at a far greater pace than the growth in the State's tax revenues.
Despite substantial tax increases, expenditure reductions and the shift of some
expenditure responsibilities to local government, the budget condition remains
problematic.
 
    In July 1996, the Governor signed into law a new $62.8 billion budget which,
among other things, significantly increases education spending from the previous
fiscal year, reduces taxes for corporations and banks and provides for a
balanced budget at the close of the fiscal year. At the same time, the budget
continues several funding reductions made in past years, mostly to health and
welfare programs. Although the state's budget provides for a reserve of $305
million, revenue and expenditure developments have occurred which may have the
effect of reducing the reserve. The Governor's proposed budget for fiscal year
1997-1998 indicates total spending of $66.6 billion and anticipates a $553
million reserve for economic uncertainties. As in past years, the state's budget
assumes savings which depend on future federal actions, both to fund programs
relating to MediCal and incarceration costs associated with undocumented
immigrants and to relieve the state from federally mandated spending, which may
not occur. Accordingly, the anticipated reserves may be reduced unless the
economy outperforms expectations or spending falls below planned levels.
 
   
    Because of California's continuing budget problems, the State's General
Obligation bonds were downgraded in July 1994 from Aa to A1 by Moody's and from
A+ to A by Standard & Poor's and from AA to A by Fitch Investment Service, Inc.
All three ratings companies expressed uncertainty in the State's ability to
balance its budget by 1996.
    
 
                                       12
<PAGE>
However, in 1996, citing California's improving economy and budget situation,
both Fitch and Standard & Poor's raised their ratings from A to A+.
 
    The effect of these various constitutional and statutory amendments and
budget developments upon the ability of California issuers to pay interest and
principal on their obligations remains unclear and in any event may depend upon
whether a particular California tax-exempt security is a general or limited
obligation bond and on the type of security provided for the bond. It is
possible that other measures affecting the taxing or spending authority of
California or its political subdivisions may be approved or enacted in the
future.

see the Statement of Additional Information.
 
PORTFOLIO MANAGEMENT
 
   
    The Fund is managed by the Investment Manager with a view to achieving the
Fund's investment objective. In determining which securities to purchase for the
Fund or hold in the Fund's portfolio, the Investment Manager will rely on
information from various sources, including research, analysis and appraisals of
brokers and dealers, including Dean Witter Reynolds Inc. ("DWR") and other
broker-dealer affiliates of InterCapital and others regarding economic
developments and interest rate trends; and the Investment Manager's own analysis
of factors it deems relevant. The Fund is managed within InterCapital's
Tax-Exempt Group, which manages 40 tax-exempt municipal funds and fund
portfolios, with approximately $10.5 billion in assets as of June 30, 1997.
James F. Willison, Senior Vice President of InterCapital and Manager of
InterCapital's Municipal Fixed-Income Group, and Joseph R. Arcieri, Vice
President of InterCapital and a member of InterCapital's Municipal Fixed-Income
Group, have been the primary portfolio managers of the Fund since its inception
and February 1997, respectively, and have been portfolio managers at
InterCapital for over five years.
    
 
   
    Securities are purchased and sold principally in response to the Investment
Manager's current evaluation of an issuer's ability to meet its debt obligations
in the future, and the Investment Manager's current assessment of future changes
in the levels of interest rates on tax-exempt securities of varying maturities.
Securities purchased by the Fund are, generally, sold by dealers acting as
principal for their own accounts (pursuant to an order issued by the Securities
and Exchange Commission, the Fund may effect principal transactions in certain
taxable money market instruments with DWR). In addition, the Fund may incur
brokerage commissions on transactions conducted through DWR and other brokers
and dealers that are affiliates of InterCapital.
    
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    The investment restrictions listed below are among the restrictions that
have been adopted by the Fund as fundamental policies. Under the Investment
Company Act of 1940, as amended (the "Act"), a fundamental policy may not be
changed without the vote of a majority of the outstanding voting securities of
the Fund, as defined in the Act.
 
    The Fund may not:
 
    1.  With respect to 75% of its total assets, purchase securities of any
issuer if immediately thereafter more than 5% of the Fund's total assets were
invested in securities of such issuer (other than obligations issued or
guaranteed by the United States Government, its agencies or instrumentalities or
by the State of California or its political subdivisions).
 
    2.  Purchase more than 10% of all outstanding taxable debt securities of any
one issuer (other than obligations issued, or guaranteed as to principal and
interest, by the United States Government, its agencies or instrumentalities).
 
    3.  Invest more than 25% of the value of its total assets in taxable
securities of issuers in any one industry. This restriction does not apply to
obligations issued or guaranteed by the United States
 
                                       13
<PAGE>
Government, its agencies or instrumentalities, or by the State of California or
its political subdivisions (industrial development and pollution control bonds
are grouped into industries based upon the business in which the issuers of such
obligations are engaged).
 
   
    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 are offered
by DWR and other dealers who have entered into agreements with the Distributor
("Selected Broker-Dealers"). The principal executive office of the Distributor
is located at Two World Trade Center, New York, New York 10048.
    
 
   
    The Fund offers four classes of shares (each, a "Class"). Class A shares are
sold to investors with an initial sales charge that declines to zero for larger
purchases; however, Class A shares sold without an initial sales charge are
subject to a contingent deferred sales charge ("CDSC") of 1.0% if redeemed
within one year of purchase, except for certain specific circumstances. Class B
shares are sold without an initial sales charge but are subject to a CDSC
(scaled down from 5.0% to 1.0%) payable upon most redemptions within six years
after purchase. Class C shares are sold without an initial sales charge but are
subject to a CDSC of 1.0% on most redemptions made within one year after
purchase. Class D shares are sold without an initial sales charge or CDSC and
are available only to investors meeting an initial investment minimum of $5
million, and to certain other limited categories of investors. At the discretion
of the Board of Trustees of the Fund, Class A shares may be sold to categories
of investors in addition to those set forth in this prospectus at net asset
value without a front-end sales charge, and Class D shares may be sold to
certain other categories of investors, in each case as may be described in the
then current prospectus of the Fund. See "Alternative Purchase
Arrangements--Selecting a Particular Class" for a discussion of factors to
consider in selecting which Class of shares to purchase.
    
 
   
    The minimum initial purchase is $1,000 for each Class of shares, although
Class D shares are only available to persons investing $5 million or more and to
certain other limited categories of investors. For the purpose of meeting the
minimum $5 million initial investment for Class D shares, and subject to the
$1,000 minimum initial investment for each Class of the Fund, an investor's
existing holdings of Class A shares of the Fund and other Dean Witter Funds that
are multiple class funds ("Dean Witter Multi-Class Funds") and shares of Dean
Witter Funds sold with a front-end sales charge ("FSC Funds") and concurrent
investments in Class D shares of the Fund and other Dean Witter Multi-Class
Funds will be aggregated. Subsequent purchases of $100 or more may be made by
sending a check, payable to Dean Witter California Tax-Free Income Fund,
directly to Dean Witter Trust Company ("Transfer Agent") at P.O. Box 1040,
Jersey City, New Jersey 07303 or by contacting an account executive of DWR or
other Selected Broker-Dealer. When purchasing shares of the Fund, investors must
specify whether the purchase is for Class A, Class B, Class C or Class D shares.
If no Class is specified, the Transfer Agent will not process the transaction
until the proper Class is identified. The minimum initial purchase in the case
of investments through EasyInvest-SM-, an automatic purchase plan (see
"Shareholder Services"), is $100, provided that the schedule of automatic
investments will result in investments totalling at least $1,000 within the
first twelve months. In the case of purchases made pursuant to systematic
payroll deduction plans, the Fund, in its discretion, may accept such purchases
without regard to any
    
 
                                       14
<PAGE>
   
minimum amounts which would otherwise be required if the Fund has reason to
believe that additional purchases will increase the amount of the purchase of
shares in all accounts under such plans to at least $1,000. Certificates for
shares purchased will not be issued unless a request is made by the shareholder
in writing to the Transfer Agent.
    
 
   
    Shares are sold through the Distributor on a normal three business day
settlement basis; that is, payment generally is due on or before the third
business day (settlement date) after the order is placed with the Distributor.
Shares of the Fund purchased through the Distributor or a Selected Broker-Dealer
are entitled to dividends beginning on the next business day following
settlement date. Since DWR and other Selected Broker-Dealers forward investors'
funds on settlement date, they will benefit from the temporary use of the funds
where payment is made prior thereto. Shares purchased through the Transfer Agent
are entitled to dividends beginning on the next business day following receipt
of an order. As noted above, orders placed directly with the Transfer Agent must
be accompanied by payment. Investors will be entitled to receive capital gains
distributions if their order is received by the close of business on the day
prior to the record date for such distributions. Sales personnel of a Selected
Broker-Dealer are compensated for selling shares of the Fund at the time of
their sale 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.
    
 
   
    ANALOGOUS DEAN WITTER FUNDS.  The Distributor and the Investment Manager
serve in the same capacities for Dean Witter Multi-State Municipal Series Trust,
California Series, an open-end investment company with investment objectives and
policies similar to those of the Fund. Shares of Dean Witter Multi-State
Municipal Series Trust, California Series, are offered to the public with a
sales charge imposed at the time of purchase. The Classes of the Fund and Dean
Witter Multi-State Municipal Series Trust, California Series have differing fees
and expenses, which will affect performance. Investors who would like to receive
a prospectus for Dean Witter Multi-State Municipal Series Trust, California
Series, should call the telephone numbers listed on the front cover of this
Prospectus, or may call their account executive for additional information.
    
 
   
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 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
    
 
                                       15
<PAGE>
   
4.25%. The initial sales charge is reduced for certain purchases. Investments of
$1 million or more (and investments by certain other limited categories of
investors) are not subject to any sales charges at the time of purchase but are
subject to a CDSC of 1.0% on redemptions made within one year after purchase,
except for certain specific circumstances. Class A shares are also subject to a
12b-1 fee of up to 0.25% of the average daily net assets of the Class. See
"Initial Sales Charge Alternative--Class A Shares."
    
 
   
    CLASS B SHARES.  Class B shares are offered at net asset value with no
initial sales charge but are subject to a CDSC (scaled down from 5.0% to 1.0%)
if redeemed within six years of purchase. This CDSC may be waived for certain
redemptions. Class B shares are also subject to an annual 12b-1 fee of 0.75% of
the lesser of: (a) the average daily aggregate gross sales of the Fund's Class B
shares since the inception of the Fund (not including reinvestments of dividends
or capital gains distributions), less the average daily aggregate net asset
value of the Fund's Class B shares redeemed since the Fund's inception upon
which a CDSC has been imposed or waived, or (b) the average daily net assets of
Class B. The Class B shares' distribution fee will cause that Class to have
higher expenses and pay lower dividends than Class A or Class D shares.
    
 
   
    After approximately ten (10) years, Class B shares will convert
automatically to Class A shares of the Fund, based on the relative net asset
values of the shares of the two Classes on the conversion date. In addition, a
certain portion of Class B shares that have been acquired through the
reinvestment of dividends and distributions will be converted at that time. See
"Contingent Deferred Sales Charge Alternative--Class B Shares."
    
 
   
    CLASS C SHARES.  Class C shares are sold at net asset value with no initial
sales charge but are subject to a CDSC of 1.0% on redemptions made within one
year after purchase. This CDSC may be waived for certain redemptions. They are
subject to an annual 12b-1 fee of up to 0.75% of the average daily net assets of
the Class C shares. The Class C shares' distribution fee may cause that Class to
have higher expenses and pay lower dividends than Class A or Class D shares. See
"Level Load Alternative--Class C Shares."
    
 
   
    CLASS D SHARES.  Class D shares are available only to limited categories of
investors (see "No Load Alternative--Class D Shares" below). Class D shares are
sold at net asset value with no initial sales charge or CDSC. They are not
subject to any 12b-1 fees. See "No Load Alternative--Class D Shares."
    
 
   
    SELECTING A PARTICULAR CLASS.  In deciding which Class of Fund shares to
purchase, investors should consider the following factors, as well as any other
relevant facts and circumstances:
    
 
   
    The decision as to which Class of shares is more beneficial to an investor
depends on the amount and intended length of his or her investment. Investors
who prefer an initial sales charge alternative may elect to purchase Class A
shares. Investors qualifying for significantly reduced or, in the case of
purchases of $1 million or more, no initial sales charges may find Class A
shares particularly attractive because similar sales charge reductions are not
available with respect to Class B or Class C shares. Moreover, Class A shares
are subject to lower ongoing expenses than are Class B or Class C shares over
the term of the investment. As an alternative, Class B and Class C shares are
sold without any initial sales charge so the entire purchase price is
immediately invested in the Fund. Any investment return on these additional
investment amounts may partially or wholly offset the higher annual expenses of
these Classes. Because the Fund's future return cannot be predicted, however,
there can be no assurance that this would be the case.
    
 
   
    Finally, investors should consider the effect of the CDSC period and any
conversion rights of the Classes in the context of their own investment time
frame. For example, although Class C shares are subject to a significantly lower
CDSC upon redemptions, they do not, unlike Class B shares, convert into Class A
shares after approximately ten years, and, therefore, are subject to an ongoing
12b-1 fee of 0.75% (rather than the 0.25% fee applicable to
    
 
                                       16
<PAGE>
   
Class A shares) for an indefinite period of time. Thus, Class B shares may be
more attractive than Class C shares to investors with longer term investment
outlooks. Other investors, however, may elect to purchase Class C shares if, for
example, they determine that they do not wish to be subject to a front-end sales
charge and they are uncertain as to the length of time they intend to hold their
shares.
    
 
   
    For the purpose of meeting the $5 million minimum investment amount for
Class D shares, holdings of Class A shares in all Dean Witter Multi-Class Funds,
shares of FSC Funds and shares of Dean Witter Funds for which such shares have
been exchanged will be included together with the current investment amount.
    
 
   
    Sales personnel may receive different compensation for selling each Class of
shares. Investors should understand that the purpose of a CDSC is the same as
that of the initial sales charge in that the sales charges applicable to each
Class provide for the financing of the distribution of shares of that Class.
    
 
   
    Set forth below is a chart comparing the sales charge, 12b-1 fees and
conversion options applicable to each Class of shares:

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

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

    Upon notice to all Selected Broker-Dealers, the Distributor may reallow up
to the full applicable sales charge as shown in the above schedule during
periods specified in such notice. During periods when 90% or more of the sales
charge is reallowed, such Selected Broker-Dealers may be deemed to be
underwriters as that term is defined in the Securities Act of 1933.
    
 
   
    The above schedule of sales charges is applicable to purchases in a single
transaction by, among others: (a) an individual; (b) an individual, his or her
spouse and their children under the age of 21 purchasing shares for his, her or
their own accounts; (c) a trustee or other fiduciary purchasing shares for a
single trust estate or a single fiduciary account; (d) a pension, profit-sharing
or other employee benefit plan qualified or non-qualified under Section 401 of
the Internal Revenue Code; (e) tax-exempt organizations enumerated in Section
501(c)(3) or (13) of the Internal Revenue Code; (f) employee benefit plans
qualified under Section 401 of the Internal Revenue Code of a single employer or
of employers who are "affiliated persons" of each other within the meaning of
Section 2(a)(3)(c) of the Act; and for investments in Individual Retirement
Accounts of employees of a single employer through Systematic Payroll Deduction
plans; or (g) any other organized group of persons, whether incorporated or not,
provided the organization has been in existence for at least six months and has
some purpose other than the purchase of redeemable securities of a registered
investment company at a discount.
    
 
   
    COMBINED PURCHASE PRIVILEGE.  Investors may have the benefit of reduced
sales charges in accordance with the above schedule by combining purchases of
Class A shares of the Fund in single transactions with the purchase of Class A
shares of other Dean Witter Multi-Class Funds and shares of FSC Funds. The sales
charge payable on the purchase of the Class A shares of the Fund, the Class A
shares of the other Dean Witter Multi-Class Funds and the shares of the FSC
Funds will be at their respective rates applicable to the total amount of the
combined concurrent purchases of such shares.
    
 
   
    RIGHT OF ACCUMULATION.  The above persons and entities may benefit from a
reduction of the sales charges in accordance with the above schedule if the
cumulative net asset value of Class A shares purchased in a single transaction,
together with shares of the Fund and other Dean Witter Funds previously
purchased at a price including a 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
    
 
                                       18
<PAGE>
   
furnished at the time of the order; or (b) a review of the records of the
Selected Broker-Dealer or the Transfer Agent fails to confirm the investor's
represented holdings.
    
 
   
    LETTER OF INTENT.  The foregoing schedule of reduced sales charges will also
be available to investors who enter into a written Letter of Intent providing
for the purchase, within a thirteen-month period, of Class A shares of the Fund
from DWR or other Selected Broker-Dealers. The cost of Class A shares of the
Fund or shares of other Dean Witter Funds which were previously purchased at a
price including a front-end sales charge during the 90-day period prior to the
date of receipt by the Distributor of the Letter of Intent, or of Class A shares
of the Fund or shares of other Dean Witter Funds acquired in exchange for shares
of such funds purchased during such period at a price including a front-end
sales charge, which are still owned by the shareholder, may also be included in
determining the applicable reduction.
    
 
   
    ADDITIONAL NET ASSET VALUE PURCHASE OPTIONS. In addition to investments of
$1 million or more, Class A shares also may be purchased at net asset value by
the following:
    
 
   
   (1) trusts for which Dean Witter Trust Company ("DWTC") or Dean Witter Trust
FSB ("DWTFSB") (each of which is an affiliate of the Investment Manager)
provides discretionary trustee services;
    
 
   
   (2) persons participating in a fee-based program approved by the Distributor,
pursuant to which such persons pay an asset based fee for services in the nature
of investment advisory or administrative services (such investments are subject
to all of the terms and conditions of such programs, which may include
termination fees and restrictions on transferability of Fund shares);
    
 
   
   (3) investors who are clients of a Dean Witter account executive who joined
Dean Witter from another investment firm within six months prior to the date of
purchase of Fund shares by such investors, if the shares are being purchased
with the proceeds from a redemption of shares of an open-end proprietary mutual
fund of the account executive's previous firm which imposed either a front-end
or deferred sales charge, provided such purchase was made within sixty days
after the redemption and the proceeds of the redemption had been maintained in
the interim in cash or a money market fund; and
    
 
   
   (4) other categories of investors, at the discretion of the Board, as
disclosed in the then current prospectus of the Fund.
    
 
   
    No CDSC will be imposed on redemptions of shares purchased pursuant to
paragraphs (1), (2) or (3), above.
    
 
   
    For further information concerning purchases of the Fund's shares, contact
DWR or another Selected Broker-Dealer or consult the Statement of Additional
Information.
    
 
   
CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE--
CLASS B SHARES
    
 
   
    Class B shares are sold at net asset value next determined without an
initial sales charge so that the full amount of an investor's purchase payment
may be immediately invested in the Fund. A CDSC, however, will be imposed on
most Class B shares redeemed within six years after purchase. The CDSC will be
imposed on any redemption of shares if after such redemption the aggregate
current value of a Class B account with the Fund falls below the aggregate
amount of the investor's purchase payments for Class B shares made during the
six years preceding the redemption. In addition, Class B shares are subject to
an annual 12b-1 fee of 0.75% 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.
    
 
   
    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
    
 
                                       19
<PAGE>
   
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:

    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
preceding the redemption; (ii) the current net asset value of shares purchased
more than six 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 other open-end investment
companies for which InterCapital serves as investment manager (collectively,
with the Fund, the "Dean Witter Funds") sold with a front-end sales charge 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; and
    
 
   
   (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.
    
 
   
    With reference to (1) above, for the purpose of determining disability, the
Distributor utilizes the definition of disability contained in Section 72(m)(7)
of the Internal Revenue Code, which relates to the inability to engage in
gainful employment. With reference to (2) above, the term "distribution" does
not encompass a direct transfer of IRA, 403(b) Custodial Account or retirement
plan assets to a successor custodian or trustee. All waivers will be granted
only following receipt by the Distributor of confirmation of the shareholder's
entitlement.
    
 
   
    CONVERSION TO CLASS A SHARES.  All shares of the Fund held prior to July 28,
1997 have been designated Class B shares. Shares held before May 1, 1997 will
convert to Class A shares in May, 2007. In all other instances Class B shares
will convert automatically to Class A shares, based on the relative net asset
values of the shares of the two Classes on the conversion date, which will be
approximately ten (10) years after the date of the original purchase. The ten
year period is calculated from the last day of the month in which the shares
were purchased or, in the case of Class B shares acquired through an exchange or
a series of exchanges, from the last day of the month in which the original
Class B shares were purchased, provided that shares originally purchased before
May 1, 1997 will convert to Class A shares in May, 2007. The conversion of
shares purchased on or after May 1, 1997 will take place in the month following
the tenth anniversary of the purchase. There will
    
 
                                       20
<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 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 0.75% of the average daily net assets of
the Class. Unlike Class B shares, Class C shares have no conversion feature and,
accordingly, an investor that purchases Class C shares will be subject to 12b-1
fees applicable to Class C shares for an indefinite period subject to annual
approval by the Fund's Board of Trustees and regulatory limitations.
    
 
   
NO LOAD ALTERNATIVE--CLASS D SHARES
    
 
   
    Class D shares are offered without any sales charge on purchase or
redemption and without any 12b-1 fee. Class D shares are offered only to
investors meeting an initial investment minimum of $5 million and the following
categories of investors: (i) investors participating in the InterCapital mutual
fund asset allocation program pursuant to which such persons pay an asset based
fee; (ii) persons participating in a fee-based program approved by the
Distributor, pursuant to which such persons pay an asset based fee for services
in the nature of investment advisory or administrative services (subject to all
of the terms and conditions of such programs, which may include termination fees
and restrictions on transferability of Fund shares); (iii) certain Unit
Investment Trusts sponsored by DWR; (iv) certain other open-end investment
companies whose shares are distributed by the Distributor; and (v) other
categories of investors, at the
    
dis-
 
                                       21
<PAGE>
   
cretion of the Board, as disclosed in the then current prospectus of the Fund.
Investors who require a $5 million minimum initial investment to qualify to
purchase Class D shares may satisfy that requirement by investing that amount in
a single transaction in Class D shares of the Fund and other Dean Witter
Multi-Class Funds, subject to the $1,000 minimum initial investment required for
that Class of the Fund. In addition, for the purpose of meeting the $5 million
minimum investment amount, holdings of Class A shares in all Dean Witter
Multi-Class Funds, shares of FSC Funds and shares of Dean Witter Funds for which
such shares have been exchanged will be included together with the current
investment amount. If a shareholder redeems Class A shares and purchases Class D
shares, such redemption may be a taxable event.
    
 
   
PLAN OF DISTRIBUTION
    
 
   
    Effective July 28, 1997, the Fund has adopted a Plan of Distribution
pursuant to Rule 12b-1 under the Act with respect to the distribution of Class
A, Class B and Class C shares of the Fund. In the case of Class A and Class C
shares, the Plan provides that the Fund will reimburse the Distributor and
others for the expenses of certain activities and services incurred by them
specifically on behalf of those shares. Reimbursements for these expenses will
be made in monthly payments by the Fund to the Distributor, which will in no
event exceed amounts equal to payments at the annual rates of 0.25% and 0.75% of
the average daily net assets of Class A and Class C, respectively. In the case
of Class B shares, the Plan provides that the Fund will pay the Distributor a
fee, which is accrued daily and paid monthly, at the annual rate of 0.75% of the
lesser of: (a) the average daily aggregate gross sales of the Fund's Class B
shares since the inception of the Fund (not including reinvestments of dividends
or capital gains distributions), less the average daily aggregate net asset
value of the Fund's Class B shares redeemed since the Fund's inception upon
which a CDSC has been imposed or waived, or (b) the average daily net assets of
Class B. The fee is treated by the Fund as an expense in the year it is accrued.
In the case of Class A shares, the entire amount of the fee currently represents
a service fee within the meaning of the NASD guidelines. In the case of Class B
and Class C shares, a portion of the fee payable pursuant to the Plan, equal to
0.20% and 0.25% of the average daily net assets of each of these Classes,
respectively, is currently characterized as a service fee. A service fee is a
payment made for personal service and/or the maintenance of shareholder
accounts.
    
 
   
    Additional amounts paid under the Plan in the case of Class B and Class C
shares are paid to the Distributor for services provided and the expenses borne
by the Distributor and others in the distribution of the shares of those
Classes, including the payment of commissions for sales of the shares of those
Classes and incentive compensation to and expenses of DWR's account executives
and others who engage in or support distribution of shares or who service
shareholder accounts, including overhead and telephone expenses; printing and
distribution of prospectuses and reports used in connection with the offering of
the Fund's shares to other than current shareholders; and preparation, printing
and distribution of sales literature and advertising materials. In addition, the
Distributor may utilize fees paid pursuant to the Plan in the case of Class B
shares to compensate DWR and other Selected Broker-Dealers for their opportunity
costs in advancing such amounts, which compensation would be in the form of a
carrying charge on any unreimbursed expenses.
    
 
   
    For the fiscal year ended December 31, 1996, Class B shares of the Fund
accrued payments under the Plan amounting to $7,504,744, which amount is equal
to 0.75% of the Fund's average daily net assets for the fiscal year. The
payments accrued under the Plan were calculated pursuant to clause (b) of the
compensation formula under the Plan. All shares held prior to July 28, 1997 have
been designated Class B shares.
    
 
   
    In the case of Class B shares, at any given time, the expenses in
distributing Class B shares of the Fund may be in excess of the total of (i) the
payments made by the Fund pursuant to the Plan, and (ii) the proceeds of CDSCs
paid by investors upon
    
 
                                       22
<PAGE>
   
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 $3,649,503 at December
31, 1996, which was equal to 0.37% of the net assets of the Fund on such date.
Because there is no requirement under the Plan that the Distributor be
reimbursed for all distribution expenses or any requirement that the Plan be
continued from year to year, such excess amount does not constitute a liability
of the Fund. Although there is no legal obligation for the Fund to pay expenses
incurred in excess of payments made to the Distributor under the Plan, and the
proceeds of CDSCs paid by investors upon redemption of shares, if for any reason
the Plan is terminated the Trustees will consider at that time the manner in
which to treat such expenses. Any cumulative expenses incurred, but not yet
recovered through distribution fees or CDSCs, may or may not be recovered
through future distribution fees or CDSCs.
    
 
   
    In the case of Class A and Class C shares, expenses incurred pursuant to the
Plan in any calendar year in excess of 0.25% or 0.75% 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.
    
 
    Certain of the Fund's portfolio securities may be valued for the Fund by an
outside independent pricing service approved by the Fund's Board of Trustees.
The pricing service utilizes a computerized grid matrix of tax-exempt securities
and evaluations by its staff in determining what it believes is the fair value
of the Fund's portfolio securities. The Board believes that timely and reliable
market quotations are generally not readily available to the Fund for purposes
of valuing tax-exempt securities and that the valuations supplied by the pricing
service are more likely to approximate the fair value of such securities.
 
    Short-term taxable debt securities with remaining maturities of sixty days
or less to maturity at time of purchase are valued at amortized cost, unless the
Board of Trustees determines such does not reflect the securities' market value,
in which case these securities will be valued at their fair market value as
determined by the Board of Trustees. The value of other assets will be
determined in good faith under procedures established by and under the
supervision of the Board of Trustees.
 
SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 
   
    AUTOMATIC INVESTMENT OF DIVIDENDS AND DISTRIBUTIONS.  All income dividends
and capital gains distributions are automatically paid in full and fractional
shares of the applicable Class of the Fund (or, if specified by the shareholder,
in shares of any other open-end Dean Witter Fund), unless the
    
 
                                       23
<PAGE>
   
shareholder requests 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"). Such dividends and
distributions will be paid, at the net asset value per share (without sales
charge), in shares of the applicable Class of the Fund (or in cash if the
shareholder so requests) on the monthly payment date, which will be no later
than the last business day of the month for which the dividend or distribution
is payable. Processing of dividend checks begins immediately following the
monthly payment date. Shareholders who have requested to receive dividends in
cash will normally receive their monthly dividend check during the first ten
days of the following month.
    
 
   
    INVESTMENT OF DIVIDENDS AND DISTRIBUTIONS RECEIVED IN CASH.  Any shareholder
who receives a cash payment representing a dividend or capital gains
distribution may invest such dividend or distribution in shares of the
applicable Class at the net asset value per share next determined after receipt
by the Transfer Agent, by returning the check or the proceeds to the Transfer
Agent within thirty days after the payment date. Shares so acquired are acquired
at net asset value and are not subject to the imposition of a front-end sales
charge or a CDSC (see "Redemptions and Repurchases").
    
 
   
    EASYINVEST-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 (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.
 
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
    
 
                                       24
<PAGE>
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 Funds shares were acquired), the holding
period (for the purpose of determining the rate of the CDSC) is frozen. If those
shares are subsequently re-exchanged for shares of a Dean Witter Multi-Class
Fund or shares of a CDSC Fund, the holding period previously frozen when the
first exchange was made resumes on the last day of the month in which shares of
a Dean Witter Multi-Class Fund or shares of a CDSC Fund are reacquired. Thus,
the CDSC is based upon the time (calculated as described above) the shareholder
was invested in shares of a Dean Witter Multi-Class Fund or in shares of a CDSC
Fund (see "Purchase of Fund Shares"). In the case of exchanges of Class A shares
which are subject to a CDSC, the holding period also includes the time
(calculated as described above) the shareholder was invested in shares of a FSC
Fund. However, in the case of shares of the Fund exchanged into the Exchange
Funds on or after April 23, 1990, upon a redemption of shares which results in a
CDSC being imposed, a credit (not to exceed the amount of the CDSC) will be
given in an amount equal to the Exchange Fund 12b-1 distribution fees incurred
on or after that date which are attributable to those shares. (Exchange Fund
12b-1 distribution fees are described in the prospectus for these funds.) Class
B shares of the Fund acquired in exchange for Class B shares of another Dean
Witter Multi-Class Fund or shares of a CDSC Fund having a different CDSC
schedule than that of this Fund will be subject to the higher CDSC schedule,
even if such shares are subsequently re-exchanged for shares of the fund with
the lower CDSC schedule.
    
 
   
    ADDITIONAL INFORMATION REGARDING EXCHANGES. Purchases and exchanges should
be made for investment purposes only. A pattern of frequent exchanges may be
deemed by the Investment Manager to be abusive and contrary to the best
interests of the Fund's other shareholders and, at the Investment Manager's
discretion, may be limited by the Fund's refusal to accept additional purchases
and/ or exchanges from the investor. Although the Fund does not have any
specific definition of what constitutes a pattern of frequent exchanges, and
will consider all relevant factors in determining whether a particular situation
is abusive and contrary to the best interests of the Fund and its other
shareholders, investors should be aware that the Fund and each of the other Dean
Witter Funds may in their discretion limit or otherwise restrict the number of
times this Exchange Privilege may be exercised by any investor. Any such
restriction will be made by the Fund on a prospective basis only, upon notice to
the shareholder not later than ten days following such shareholder's most recent
exchange. Also, the Exchange Privilege may be terminated or revised at any time
by the Fund and/or any of such Dean Witter Funds for which shares of the Fund
may be exchanged, upon such notice as may be required by applicable regulatory
agencies. Shareholders maintaining margin accounts with DWR or another Selected
Broker-Dealer are referred to their account executive regarding restrictions on
exchange of shares of the Fund pledged in their margin account.
    
 
    The current prospectus for each fund describes its investment objective(s)
and policies, and shareholders should obtain one and read it carefully
 
                                       25
<PAGE>
   
before investing. Exchanges are subject to the minimum investment requirement of
each Class of shares and any other conditions imposed by each fund. In the case
of a shareholder holding a share certificate or certificates, no exchanges may
be made until all applicable share certificates have been received by the
Transfer Agent and deposited in the shareholder's account. An exchange will be
treated for federal income tax purposes the same as a repurchase or redemption
of shares on which the shareholder has realized a capital gain or loss. However,
the ability to deduct capital losses on an exchange may be limited in situations
where there is an exchange of shares within ninety days after the shares are
purchased. There are also limits on the deduction of losses after the payment of
exempt-interest dividends for shares held for less than six months (see
"Dividends, Distributions and Taxes"). 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 other Selected Broker-Dealers 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 Dealer account
number (if any). Telephone instructions may also be recorded. If such procedures
are not employed, the Fund may be liable for any losses due to unauthorized or
fraudulent instructions.
 
    Telephone exchange instructions will be accepted if received by the Transfer
Agent between 9:00 a.m. and 4:00 p.m. New York time, on any day the New York
Stock Exchange is open. Any shareholder wishing to make an exchange who has
previously filed an Exchange Privilege Authorization Form and who is unable to
reach the Fund by telephone should contact his or her DWR or other Selected
Broker-Dealer account executive, if appropriate, or make a written exchange
request. Shareholders are advised that during periods of drastic economic or
market changes, it is possible that the telephone exchange procedures may be
difficult to implement, although this has not been the case with the Dean Witter
Funds in the past.
 
   
    For further information regarding the Exchange Privilege, shareholders
should contact their DWR or other Selected Broker-Dealer account executives or
the Transfer Agent.
    
 
REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 
   
    REDEMPTION.  Shares of each Class of the Fund can be redeemed for cash at
any time at the net asset value per share next determined less the amount of any
applicable CDSC in the case of Class A, Class B or Class C shares (see "Purchase
of Fund Shares"). If shares are held in a shareholder's account without a share
certificate, a written request for redemption to the Fund's Transfer Agent at
P.O. Box 983, Jersey City, New Jersey 07303 is required. If certificates are
held by the shareholder, the shares may be redeemed by surrendering the
certificates with a written request of redemption, along with any additional
information required by the Transfer Agent.
    
 
                                       26
<PAGE>
   
    REPURCHASE.  DWR and other Selected Broker-Dealers are authorized to
repurchase shares represented by a share certificate which is delivered to any
of their offices. Shares held in a shareholder's account without a share
certificate may also be repurchased by DWR or 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-Dealers, 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 or other Selected Broker-Dealers to repurchase
shares may be suspended without notice by them at any time. In that event,
shareholders may redeem their shares through the Fund's Transfer Agent as set
forth above under "Redemption."
    
 
    PAYMENT FOR SHARES REDEEMED OR REPURCHASED.  Payment for shares presented
for repurchase or redemption will be made by check within seven days after
receipt by the Transfer Agent of the certificate and/or written request in good
order. Such payment may be postponed or the right of redemption suspended under
unusual circumstances. If the shares to be redeemed have recently been purchased
by check, payment of the redemption proceeds may be delayed for the minimum time
needed to verify that the check used for investment has been honored (not more
than fifteen days from the time of receipt of the check by the Transfer Agent).
Shareholders maintaining margin accounts with DWR or other Selected
Broker-Dealers are referred to their account executive regarding restrictions on
redemption of shares of the Fund pledged in their 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 to redeem, on sixty
days' notice and at net asset value, the shares of any shareholder (other than
shares held in an Individual Retirement Account or Custodial Account under
Section 403(b)(7) of the Internal Revenue Code) whose shares due to redemptions
by the shareholder have a value of less than $100 or such lesser amount as may
be fixed by the Board of Trustees or, in the case of an account opened through
EasyInvest, if after twelve months, the shareholder has invested less than
$1,000 in the account. However, before the Fund redeems such shares and sends
the proceeds to the shareholder, it will notify the shareholder that the value
of the shares is less than the applicable amount and allow him or her sixty days
to make an additional investment in an amount which will increase the value of
his or her 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 from net investment income on each day the New York Stock
Exchange is open for business to shareholders of record as of the close of
business the preceding business day. The amount of such dividends may fluctuate
from day to day. Such dividends are paid monthly.
    
 
   
    The Fund will distribute at least once each year all net realized short-term
capital gains in excess of any realized net long-term capital losses, if any.
The
    
 
                                       27
<PAGE>
   
Fund intends to distribute all of its realized net long-term capital gains, if
any, in excess of any realized net short-term capital losses and any available
net capital loss carryovers, at least once per fiscal year, although it may
elect to retain all or part of such gains for reinvestment. Taxable capital
gains may be generated by the sale of portfolio securities and by transactions
in options and futures contracts engaged in by the Fund.
    
 
   
    All dividends and any capital gains distributions will be paid in additional
shares of the same Class and automatically credited to the shareholder's account
without issuance of a share certificate unless the shareholder requests in
writing that all dividends be paid in cash. Shares acquired by dividend and
distribution reinvestments will not be subject to any front-end sales charge or
CDSC. Class B shares acquired through dividend and distribution reinvestments
will become eligible for conversion to Class A shares on a pro rata basis.
Distributions paid on Class A and Class D shares will be higher than for Class B
and Class C shares because distribution fees paid by Class B and Class C shares
are higher. (See "Shareholder Services--Automatic Investment of Dividends and
Distributions".) Any dividends declared in the last quarter of any calendar year
which are paid in the following calendar year prior to February 1 will be deemed
received by the shareholder in the prior calendar year.
    
 
   
    TAXES.  Because the Fund intends to distribute substantially all of its net
investment income and capital gains to shareholders and intends to otherwise
comply with all the provisions of Subchapter M of the Internal Revenue Code (the
"Code") to qualify as a regulated investment company, it is not expected that
the Fund will be required to pay any federal income tax. Taxable capital gains
may be generated by transactions in options and futures contracts engaged in by
the Fund.
    
 
    The Fund intends to qualify to pay "exempt-interest dividends" to its
shareholders by maintaining, as of the close of each quarter of its taxable
year, at least 50% of the value of its total assets in tax-exempt securities. If
the Fund satisfies such requirement, then distributions from net investment
income to shareholders will be exempt from federal taxation to the extent net
investment income is represented by interest on tax-exempt securities.
Shareholders generally will not incur any federal income tax on the amount of
exempt-interest dividends received by them from the Fund, whether taken in cash
or reinvested in additional shares. Exempt-interest dividends are included,
however, in determining what portion, if any, of a person's Social Security
benefits are subject to federal income tax.
 
    The Code may subject interest received on certain otherwise tax-exempt
securities to an alternative minimum tax. This alternative minimum tax may be
incurred due to interest received on "private activity bonds" (in general, bonds
that benefit non-government entities) issued after August 7, 1986 which,
although tax-exempt, are used for purposes other than those generally performed
by governmental units (e.g., bonds used for commercial or housing purposes).
Income received on such bonds is classified as a "tax preference item", under
the alternative minimum tax, for both individual and corporate investors. A
portion of the Fund's investments may be made in such "private activity bonds,"
with the result that a portion of the exempt-interest dividends paid by the Fund
will be an item of tax preference to shareholders subject to the alternative
minimum tax. In addition, certain corporations which are subject to the
alternative minimum tax may have to include a portion of exempt-interest
dividends in calculating their alternative minimum taxable income in situations
where the "adjusted current earnings" of the corporation exceeds its alternative
minimum taxable income.
 
    Under California law, a fund which qualifies as a regulated investment
company must have at least 50% of its total assets invested in California state
and local issues (or in obligations of the United States which pay interest
excludable from income) at the end of each quarter of its taxable year in order
to be eligible to pay dividends which will be exempt from California personal
income tax. Shareholders who are California residents will not incur any federal
or California income tax on the amount of exempt-interest dividends received by
them from
 
                                       28
<PAGE>
the Fund and derived from California state and local issues, whether taken in
cash or reinvested in additional shares.
 
    After the end of the calendar year, the shareholders will be sent a
statement indicating the percentage of the dividend distributions for such
fiscal year which constitutes exempt-interest dividends and the percentage, if
any, that is taxable, and the percentage, if any, of the exempt-interest
dividends which constitutes an item of tax preference. Unlike federal law,
California law provides that no portion of the exempt-interest dividends will
constitute an item of tax preference for California personal income tax
purposes. Moreover, unlike federal law, an individual's Social Security benefits
are not subject to California personal income tax, so that the receipt of
California exempt-interest dividends will have no effect on an individual's
California personal income tax.
 
    Under the Revenue Reconciliation Act of 1993, all or a portion of the Fund's
gain from the sale or redemption of tax-exempt obligations purchased at a market
discount after April 30, 1993 will be treated as ordinary income rather than
capital gain. This rule may increase the amount of ordinary income dividends
received by shareholders.
 
    Shareholders will normally be subject to federal and California personal
income tax on dividends paid from interest income derived from taxable
securities and on distributions of net capital gains. For federal income tax and
California personal income tax purposes, distributions of 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. In
addition, unlike federal law, the shareholders of the Fund will not be subject
to tax, or receive a credit for tax paid by the Fund, on undistributed capital
gains, if any. To avoid being subject to a 31% backup withholding tax on taxable
dividends and capital gains distributions and the proceeds of redemptions and
repurchases, shareholders' taxpayer identification numbers must be furnished and
certified as to accuracy.
 
    The Fund may at times make payments from sources other than income or net
capital gains. Payments from such sources will, in effect, represent a return of
a portion of each shareholder's investment. All, or a portion, of such payments
will not be taxable to shareholders.
 
    Any loss on the sale or exchange of shares of the Fund which are held for
six months or less is disallowed to the extent of the amount of any
exempt-interest dividend paid with respect to such shares. Treasury Regulations
may provide for a reduction in such required holding periods. If a shareholder
receives a distribution that is taxed as a long-term capital gain on shares held
for six months or less and sells those shares at a loss, the loss will be
treated as a long-term capital loss.
 
    Interest on indebtedness incurred by shareholders or related parties to
purchase or carry shares of an investment company paying exempt-interest
dividends, such as the Fund, will not be deductible by the investor for federal
or state personal income tax purposes.
 
    The foregoing relates to federal income taxation and to California personal
income taxation as in effect as of the date of this Prospectus. Distributions
from investment income and capital gains, including exempt-interest dividends,
may be subject to California franchise taxes if received by a corporation doing
business in California, to state taxes in states other than California and to
local taxes.
 
    Shareholders should consult their tax adviser as to the applicability of the
above to their own tax situation.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
   
    From time to time the Fund may quote its "yield" and/or its "total return"
in advertisements and sales literature. These figures are computed separately
for Class A, Class B, Class C and Class D
    
 
                                       29
<PAGE>
   
shares. Both the yield and the total return of the Fund are based on historical
earnings and are not intended to indicate future performance. The yield of each
Class of the Fund is computed by dividing the Class's net investment income over
a 30-day period by an average value (using the average number of shares entitled
to receive dividends and the maximum offering price per share at the end of the
period), all in accordance with applicable regulatory requirements. Such amount
is compounded for six months and then annualized for a twelve-month period to
derive the Fund's yield for each Class. The Fund may also quote its
tax-equivalent yield, which is calculated by determining the pre-tax yield for
each Class which, after being taxed at a stated rate, would be equivalent to the
yield determined as described above.
    
 
   
    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 a period of one, five,
ten years, or over the life of the Fund. 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, under
ordinary circumstances, the Fund does not intend to hold such meetings. The
Trustees may call Special Meetings of Shareholders for action by shareholder
vote as may be required by the Act or the Declaration of Trust. Under certain
circumstances the Trustees may be removed by action of the Trustees or by the
Shareholders.
 
    Under Massachusetts law, shareholders of a business trust may, under certain
circumstances, be held personally liable as partners for the obligations of the
Fund. However, the Declaration of Trust contains an express disclaimer of
shareholder liability for acts or obligations of the Fund, requires that Fund
obligations include such disclaimer, and provides for indemnification and
reimbursement of expenses out of the Fund's property for any shareholder held
personally liable for the obligations of the Fund. Thus, the risk of a
shareholder incurring financial loss on account of shareholder liability is
limited to circumstances in which the Fund itself would be unable to meet its
obligations. Given the above limitations on shareholder personal liability and
the nature of the Fund's assets and operations, the possibility of the Fund
being unable to meet its obligations is remote and, in the opinion of
Massa-
 
                                       30
<PAGE>
chusetts counsel to the Fund, the risk to Fund shareholders of personal
liability is remote.
 
    CODE OF ETHICS.  Directors, officers and employees of InterCapital, Dean
Witter Services Company Inc. and the Distributor are subject to a strict Code of
Ethics adopted by those companies. The Code of Ethics is intended to ensure that
the interests of shareholders and other clients are placed ahead of any personal
interest, that no undue personal benefit is obtained from a person's employment
activities and that actual and potential conflicts of interest are avoided. To
achieve these goals and comply with regulatory requirements, the Code of Ethics
requires, among other things, that personal securities transactions by employees
of the companies be subject to an advance clearance process to monitor that no
Dean Witter Fund is engaged at the same time in a purchase or sale of the same
security. The Code of Ethics bans the purchase of securities in an initial
public offering and prohibits engaging in futures and options transactions and
profiting on short-term trading (that is, a purchase within 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

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
April 9, 1984.
 
THE INVESTMENT MANAGER
 
   
    Dean Witter InterCapital Inc., a Delaware corporation, (the "Investment
Manager" or "InterCapital"), 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 Dean Witter InterCapital Inc.
thereafter.) The daily management of the Fund and research relating to the
Fund's portfolio is conducted by or under the direction of officers of the Fund
and of the Investment Manager, subject to periodic review by the Fund's Board of
Trustees. Information as to these trustees and officers is contained under the

collectively referred to as the Dean Witter Funds. In addition, Dean Witter
Services Company Inc. ("DWSC"), a wholly-owned subsidiary of InterCapital,
serves as manager for the following companies for which TCW Funds Management,
Inc. is the investment adviser: TCW/DW Core Equity Trust, TCW/DW North American
Government Income Trust, TCW/DW Latin American Growth Fund, TCW/DW Income and
Growth Fund, TCW/DW SmallCap Growth Fund, TCW/DW Balanced Fund, TCW/DW Mid-Cap

Funds"). InterCapital also serves as: (i) administrator of The BlackRock
Strategic Term Trust Inc., a closed-end investment company; and (ii)
sub-administrator of MassMutual Participation Investors and Templeton Global
Governments Income Trust, closed-end investment companies.
    
 
    Pursuant to an Investment Management Agreement (the "Agreement") with the
Investment Manager, the Fund has retained the Investment Manager to manage the
investment of the Fund's assets, including the placing of orders for the
purchase and sale of portfolio securities. The Investment Manager obtains and
evaluates such information and advice relating to the economy, securities
markets, and specific securities as it considers necessary or useful to
continuously manage the assets of the Fund in a manner consistent with its
investment objective and policies.
 
    Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes, at its own expense, such office space, facilities,
equipment, clerical help, bookkeeping and certain legal services as the Fund may
reasonably require in the conduct of its business, including the preparation of
prospectuses, proxy statements and reports required to be filed with federal and
state securities commissions (except insofar as the participation or assistance
of independent accountants and attorneys is, in the opinion of the Investment
Manager, necessary or desirable). In addition, the Investment Manager pays the
salaries of all personnel, including officers of the Fund, who are employees of
the Investment Manager. The Investment Manager also bears the cost of telephone
service, heat, light, power and other utilities provided to the Fund.
 
    Effective December 31, 1993, pursuant to a Services Agreement between
InterCapital and DWSC, DWSC began to provide the administrative services to the
Fund which were previously performed directly by InterCapital. On April 17,
1995, DWSC was reorganized in the State of Delaware, necessitating the entry
into a new Services Agreement by InterCapital and DWSC on that date. The
foregoing internal 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: fees pursuant to any plan of distribution
(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 stock certificates; registration
costs of the Fund and its shares under federal and state securities laws; the
cost and expense of printing, including typesetting, and distributing
prospectuses and statements of additional information of the Fund and
supplements thereto to the Fund's shareholders; all expenses of shareholders'
and Trustees' meetings and of preparing, printing and mailing of proxy
statements and reports to shareholders; fees and travel expenses of Trustees or
members of any advisory board or committee who are not employees of the
Investment Manager or any corporate affiliate of the Investment Manager; all
expenses incident to any dividend, withdrawal or redemption options; charges and
expenses of any outside service used for pricing of the Fund's shares; fees and
expenses of legal counsel, including counsel to the Trustees who are not
interested persons of the Fund or of the Investment Manager (not including
compensation or expenses of attorneys who are
    
 
                                       4
<PAGE>
   
employees of the Investment Manager), and independent accountants; membership
dues of industry associations; interest on Fund borrowings; postage; insurance
premiums on property or personnel (including officers and trustees) of the Fund
which inure to its benefit; extraordinary expenses (including, but not limited
to, legal claims and liabilities and litigation costs and any indemnification
relating thereto); and all other costs of the Fund's operation. The 12b-1 fees
relating to a particular Class will be allocated directly to that Class. In
addition, other expenses associated with a particular Class (except advisory or
custodial fees) may be allocated directly to that Class, provided that such
expenses are reasonably identified as specifically attributable to that Class
and the direct allocation to that Class is approved by the Trustees.
    
 
    As full compensation for the services and facilities furnished to the Fund
and expenses of the Fund assumed by the Investment Manager, the Fund pays the
Investment Manager monthly compensation calculated daily by applying the annual
rate of 0.55% to the portion of the Fund's net assets not exceeding $500
million; 0.525% to the portion of the Fund's net assets exceeding $500 million
but not exceeding $750 million, 0.50% to the portion of the Fund's net assets
exceeding $750 million but not exceeding $1 billion; and 0.475% of the portion
of daily net assets exceeding $1 billion. Total operating expenses of the Fund
are subject to applicable limitations under rules and regulations of states
where the Fund is authorized to sell its shares, as the same may be amended from
time to time. For the fiscal years ended December 31, 1994, 1995 and 1996, the
Fund accrued to the Investment Manager total compensation under the Agreement in
the amounts of $5,824,889, $5,513,580 and $5,313,150, 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 does not restrict 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 Special Meeting of
Shareholders held on May 21, 1997. The Agreement is substantially identical to a
prior investment management agreement which was initially approved by the Board
of Trustees on October 22, 1992 and by the shareholders of the Fund at a Special
Meeting of Shareholders held on January 12, 1993. The Agreement took effect on
May 31, 1997 upon the consummation of the merger of Dean Witter, Discover & Co.
with Morgan Stanley Group Inc. The Agreement may be terminated at any time,
without penalty, on thirty days' notice by the Board of Trustees of the Fund, by
the holders of a majority, as defined in the Investment Company Act of 1940 (the
"Act"), of the outstanding shares of the Fund, or by the Investment Manager. The
Agreement will automatically terminate in the event of its assignment (as
defined in the Act).
    
 
   
    Under its terms, the Agreement has an initial term ending April 30, 1999 and
provides that it 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 Board of Trustees of the Fund; provided that in either event
such continuance is approved annually by the vote of a majority of the
Independent Trustees, which vote must be cast in person at a meeting called for
the purpose of voting on such approval. At their meeting held on April 17, 1996,
the Fund's Board of Trustees, including all of the Independent Trustees,
approved continuance of the Agreement until April 30, 1997.
    
 
    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 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 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.
    
 
                                       8
<PAGE>
   
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 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-
    
 
                                       9
<PAGE>
   
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.
    
 
   
CASH 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.
 
    The following table illustrates the compensation paid to the Fund's
Independent Trustees by the Fund for the fiscal year ended December 31, 1996.

    As of the date of this Statement of Additional Information, 57 of the Dean
Witter Funds, including the Fund, have adopted a retirement program under which
an Independent 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.
 
    The following table illustrates the retirement benefits accrued to the
Fund's Independent Trustees by the Fund for the fiscal year ended December 31,
1996 and by the 57 Dean Witter Funds (including the Fund) for the year ended
December 31, 1996, and the estimated retirement benefits for the Fund's
Independent Trustees, to commence upon their retirement, from the Fund as of
December 31, 1996 and from the 57 Dean Witter Funds as of December 31, 1996.

    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.
 
(2)  Based on current levels of compensation. Amount of annual benefits also
    varies depending on the Trustee's elections described in Footnote (1) above.
 
(3)  This number reflects the effect of the extension of Mr. Haire's term as
    Trustee until June 1, 1998.
 
    As of the date of this Statement of Additional Information, the aggregate
number of shares of beneficial interest of the Fund owned by the Fund's officers
and Trustees as a group was less than 1 percent of the Fund's shares of
beneficial interest outstanding.

INVESTMENT PRACTICES AND POLICIES
- --------------------------------------------------------------------------------
 
PORTFOLIO SECURITIES
 
    TAXABLE SECURITIES.  As discussed in the Prospectus, the Fund may invest up
to 20% of its total assets in taxable money market instruments, non-California
tax-exempt securities, futures and options. Investments in taxable money market
instruments would generally be made under any one of the following
circumstances: (a) pending investment of proceeds of sale of Fund shares or of
portfolio securities, (b) pending settlement of purchases of portfolio
securities and (c) to maintain liquidity for the purpose of meeting anticipated
redemptions. Only those non-California tax-exempt securities which satisfy the
standards established for California tax-exempt securities may be purchased by
the Fund.
 
    In addition, the Fund may temporarily invest more than 20% of its total
assets in non-California tax-exempt securities and taxable money market
instruments, or in tax-exempt securities subject to the federal alternative
minimum tax for individual shareholders, to maintain a "defensive" posture when,
in the opinion of the Investment Manager, it is advisable to do so because of
market conditions. The types of taxable money market instruments in which the
Fund may invest are limited to the following short-term fixed-income securities
(maturing in one year or less from the time of purchase): (i) obligations of the
United States Government, its agencies, instrumentalities or authorities; (ii)
commercial paper rated P-1 by Moody's Investors Service, Inc. ("Moody's") or A-1
by Standard & Poor's Corporation ("S&P"); (iii) certificates of deposit of
domestic banks with assets of $1 billion or more; and (iv) repurchase agreements
with respect to portfolio securities.
 
    TAX-EXEMPT SECURITIES.  As discussed in the Prospectus, at least 80% of the
Fund's total assets will be invested in California tax-exempt securities
(California Municipal Bonds, California Municipal Notes and California Municipal
Commercial Paper). In regard to the Moody's and S&P ratings discussed in the
Prospectus, it should be noted that the ratings represent the organizations'
opinions as to the quality of the securities which they undertake to rate and
that the ratings are general and not absolute standards of quality. For a
description of Municipal Bond, Municipal Note and Municipal Commercial Paper
ratings by Moody's and S&P, see the Appendix to this Statement of Additional
Information.
 
    The Fund does not have any minimum quality rating standard for its
downgraded investments. As such, the Fund may invest in securities rated as low
as Caa, Ca or C by Moody's or CCC, CC, C or CI by S&P. Bonds rated Caa or Ca by
Moody's may already be in default on payment of interest or principal, while
bonds rated C by Moody's, their lowest bond rating, can be regarded as having
extremely poor prospects of ever attaining any real investment standing. Bonds
rated CI by S&P, their lowest bond rating, are no longer making interest
payments.
 
    The payment of principal and interest by issuers of certain Municipal
Obligations purchased by the Fund may be guaranteed by letters of credit or
other credit facilities offered by banks or other financial institutions. Such
guarantees will be considered in determining whether a Municipal Obligation
meets the Fund's investment quality requirements. In addition, some issues may
contain provisions which permit the Fund to demand from the issuer repayment of
principal at some specified period(s) prior to maturity.
 
    MUNICIPAL BONDS.  Municipal Bonds, as referred to in the Prospectus, are
debt obligations of a state, its cities, municipalities and municipal agencies
(all of which are generally referred to as "municipalities") which generally
have a maturity at the time of issue of one year or more, and the interest from
which is, in the opinion of bond counsel, exempt from federal income tax. In
addition to these requirements, the interest from California Municipal Bonds
must be, in the opinion of bond counsel, exempt from California personal income
tax. They are issued to raise funds for various public purposes, such as
construction of a wide range of public facilities, to refund outstanding
obligations and to obtain funds for general operating expenses or to loan to
other public institutions and facilities. In addition, certain types of
industrial development bonds and pollution control bonds are issued by or on
behalf of public authorities to provide funding for various privately operated
facilities.
 
                                       12
<PAGE>
    MUNICIPAL NOTES.  Municipal Notes are short-term obligations of
municipalities, generally with a maturity at the time of issuance ranging from
six months to three years, the interest from which is, in the opinion of bond
counsel, exempt from federal income tax. In addition to those requirements, the
interest from California Municipal Notes must be, in the opinion of bond
counsel, exempt from California personal income tax. The principal types of
Municipal Notes include tax anticipation notes, bond anticipation notes, revenue
anticipation notes and project notes, although there are other types of
Municipal Notes in which the Fund may invest. Notes sold in anticipation of
collection of taxes, a bond sale or receipt of other revenues are usually
general obligations of the issuing municipality or agency. Project Notes are
issued by local agencies and are guaranteed by the United States Department of
Housing and Urban Development. Such notes are secured by the full faith and
credit of the United States Government.
 
    MUNICIPAL COMMERCIAL PAPER.  Municipal Commercial Paper refers to short-term
obligations of municipalities the interest from which is, in the opinion of bond
counsel, exempt from federal income tax. In addition to those requirements, the
interest from California Commercial Paper must be, in the opinion of bond
counsel, exempt from California personal income tax. It may be issued at a
discount and is sometimes referred to as Short-Term Discount Notes. Municipal
Commercial Paper is likely to be used to meet seasonal working capital needs of
a municipality or interim construction financing and to be paid from general
revenues of the municipality or refinanced with long-term debt. In most cases
Municipal Commercial Paper is backed by letters of credit, lending agreements,
note repurchase agreements or other credit facility agreements offered by banks
or other institutions.
 
    Issuers of Municipal Obligations are subject to the provisions of
bankruptcy, insolvency and other laws affecting the rights and remedies of
creditors, such as the Federal Bankruptcy Act, and laws, if any, which may be
enacted by Congress or any state extending the time for payment of principal or
interest, or both, or imposing other constraints upon enforcement of such
obligations or upon municipalities to levy taxes. There is also the possibility
that as a result of litigation or other conditions the power or ability of any
one or more issuers to pay, when due, principal of and interest on its, or
their, Municipal Bonds, Municipal Notes and Municipal Commercial Paper may be
materially affected.
 
RISK CONSIDERATIONS
 
    Because of the special nature of securities which are rated below investment
grade by national credit rating agencies ("lower-rated securities"), the
Investment Manager must take into account certain special considerations in
assessing the risks associated with such investments. For example, as the
lower-rated securities market is relatively new, its growth has paralleled a
long economic expansion and it has not weathered a recession in its present size
and form. Therefore, an economic downturn or increase in interest rates is
likely to have a negative effect on this market and on the value of the lower-
rated securities held by the Fund, as well as on the ability of the securities'
issuers to repay principal and interest on their borrowings.
 
    The prices of lower-rated securities have been found to be less sensitive to
changes in prevailing interest rates than higher-rated investments, but are
likely to be more sensitive to adverse economic changes or individual
issuer/debtor developments. During an economic downturn or substantial period of
rising interest rates, highly leveraged issuers may experience financial stress
which would adversely affect their ability to service their principal and
interest payment obligations, to meet their projected business goals or to
obtain additional financing. If the issuer of a fixed-income security owned by
the Fund defaults, the Fund may incur additional expenses to seek recovery. In
addition, periods of economic uncertainty and change can be expected to result
in an increased volatility of market prices of lower-rated securities and a
concomitant volatility in the net asset value of a share of the Fund. Moreover,
the market prices of certain of the Fund's portfolio securities which are
structured as zero coupon securities are affected to a greater extent by
interest rate changes and thereby tend to be more volatile than securities which
pay interest periodically and in cash (see "Dividends, Distributions and Taxes"
for a discussion of the tax ramifications of investments in such securities).
 
                                       13
<PAGE>
    The secondary market for lower-rated securities may be less liquid than the
markets for higher quality securities and, as such, may have an adverse effect
on the market prices of certain securities. The limited liquidity of the market
may also adversely affect the ability of the Fund's Trustees to arrive at a fair
value for certain lower-rated securities at certain times and should make it
difficult for the Fund to sell certain securities.
 
    New laws and proposed new laws may have a potentially negative impact on the
market for lower-rated securities. For example, recent legislation requires
federally-insured savings and loan associations to divest their investments in
lower-rated securities. This legislation and other proposed legislation may have
an adverse effect upon the value of lower-rated securities and a concomitant
negative impact upon the net asset value of a share of the Fund.
 
    VARIABLE RATE OBLIGATIONS.  As stated in the Prospectus, the Fund may invest
in obligations of the type called "variable rate obligations." The interest rate
payable on a variable rate obligation is adjusted either at predesignated
periodic intervals or whenever there is a change in the market rate of interest
on which the interest rate payable is based. Other features may include the
right whereby the Fund may demand prepayment of the principal amount of the
obligation prior to its stated maturity (a "demand feature") and the right of
the issuer to prepay the principal amount prior to maturity. The principal
benefit of a variable rate obligation is that the interest rate adjustment
minimizes changes in the market value of the obligation. The principal benefit
to the Fund of purchasing obligations with a demand feature is that liquidity,
and the ability of the Fund to obtain repayment of the full principal amount of
the obligation prior to maturity, is enhanced.
 
    LENDING OF PORTFOLIO SECURITIES.  The Fund may lend portfolio securities to
brokers, dealers and financial institutions provided that cash equal to at least
100% of the market value of the securities loaned is deposited by the borrower
with the Fund and is maintained each business day in a segregated account
pursuant to applicable regulations. While such securities are on loan, the
borrower will pay the Fund any income accruing thereon, and the Fund may invest
the cash collateral in portfolio securities, thereby earning additional income.
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. Loans
would be subject to termination by the Fund in the normal settlement time,
currently five business days after notice, or by the borrower on one day's
notice. Borrowed securities must be returned when the loan is terminated. Any
gain or loss in the market price of the borrowed securities which occurs during
the term of the loan inures to the Fund and its shareholders. The Fund may pay
reasonable finders, borrowers, administrative, and custodial fees in connection
with a loan. During the fiscal year ended December 31, 1996, the Fund did not
loan its portfolio securities and it has no current intention to loan its
portfolio securities in the forseeable future.
 
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS
 
    As discussed in the Prospectus, from time to time, in the ordinary course of
business, the Fund may purchase securities on a when-issued or delayed delivery
basis and may purchase or sell securities on a forward commitment basis. When
such transactions are negotiated, the price is fixed at the time of the
commitment, but delivery and payment can take place a month or more after the
date of the commitment. The securities so purchased are subject to market
fluctuation and no interest accrues to the purchaser during this period. While
the Fund will only purchase securities on a when-issued, delayed delivery or
forward commitment basis with the intention of acquiring the securities, the
Fund may sell the securities before the settlement date, if it is deemed
advisable. At the time the Fund makes the commitment to purchase securities on a
when-issued or delayed delivery basis, the Fund will record the transaction and
thereafter reflect the value, each day, of such security in determining the net
asset value of the Fund. At the time of delivery of the securities, the value
may be more or less than the purchase price. The Fund will also establish a
segregated account with the Fund's custodian bank in which it will continuously
maintain cash or U.S. Government securities or other liquid portfolio securities
equal in value to commitments for such when-issued or delayed delivery
securities; subject to this requirement, the Fund may purchase securities on
such basis without limit. An increase in the percentage of the Fund's assets
committed to the purchase of securities on a when-issued or delayed delivery
basis may
 
                                       14
<PAGE>
increase the volatility of the Fund's net asset value. The Investment Manager
and the Trustees do not believe that the Fund's net asset value or income will
be adversely affected by its purchase of securities on such basis.
 
HEDGING ACTIVITIES
 
    The Fund may enter financial futures contracts, options on such futures and
municipal bond index futures contracts for hedging purposes.
 
FUTURES CONTRACTS AND OPTIONS ON FUTURES
 
    As discussed in the Prospectus, the Fund may invest in financial futures
contracts ("futures contracts") and related options thereon. These futures
contracts and related options thereon will be used only as a hedge against
anticipated interest rate changes. A futures contract sale creates an obligation
by the Fund, as seller, to deliver the specific type of instrument called for in
the contract at a specified future time for a specified price. A futures
contract purchase would create an obligation by the Fund, as purchaser, to take
delivery of the specific type of financial instrument at a specified future time
at a specified price. The specific securities delivered or taken, respectively,
at settlement date, would not be determined until or near that date. The
determination would be in accordance with the rules of the exchange on which the
futures contract sale or purchase was effected.
 
    Although the terms of futures contracts specify actual delivery or receipt
of securities, in most instances the contracts are closed out before the
settlement date without the making or taking of delivery of the securities.
Closing out of a futures contract is usually effected by entering into an
offsetting transaction. An offsetting transaction for a futures contract sale is
effected by the Fund entering into a futures contract purchase for the same
aggregate amount of the specific type of financial instrument at the same
delivery date. If the price in the sale exceeds the price in the offsetting
purchase, the Fund is immediately paid the difference and thus realizes a gain.
If the offsetting purchase price exceeds the sale price, the Fund pays the
difference and realizes the loss. Similarly, the closing out of a futures
contractpurchase is effected by the Fund entering into a futures contract sale.
If the offsetting sale price exceeds the purchase price the Fund realizes a
gain, and if the offsetting sale price is less than the purchase price the Fund
realizes a loss.
 
    Unlike a futures contract, which requires the parties to buy and sell a
security on a set date, an option on a futures contract entitles its holder to
decide on or before a future date whether to enter into such a contract. If the
holder decides not to enter into the contract, the premium paid for the option
is lost. Since the value of the option is fixed at the point of sale, there are
no daily payments of cash to reflect the change in the value of the underlying
contract, as discussed below for futures contracts. The value of the option
changes and is reflected in the net asset value of the Fund.
 
    The Fund is required to maintain margin deposits with brokerage firms
through which it effects futures contracts and options thereon. The initial
margin requirements vary according to the type of the underlying security. In
addition, due to current industry practice daily variations in gains and losses
on open contracts are required to be reflected in cash in the form of variation
margin payments. The Fund may be required to make additional margin payments
during the term of the contract.
 
    Currently, futures contracts can be purchased on debt securities such as
U.S. Treasury Bills and Bonds, U.S. Treasury Notes with maturities between 6 1/2
and 10 years, Certificates of the Government National Mortgage Association and
Bank Certificates of Deposit. The Fund may invest in interest rate futures
contracts covering these types of financial instruments as well as in new types
of contracts that become available in the future.
 
    Financial futures contracts are traded in an auction environment on the
floors of several Exchanges -- principally, the Chicago Board of Trade, the
Chicago Mercantile Exchange and the New York Futures Exchange. Each Exchange
guarantees performance under contract provisions through a clearing corporation,
a nonprofit organization managed by the Exchange membership which is also
responsible for handling daily accounting of deposits or withdrawals of margin.
 
                                       15
<PAGE>
    A risk in employing futures contracts to protect against the price
volatility of portfolio securities is that the prices of securities subject to
futures contracts may correlate imperfectly with the behavior of the cash prices
of the Fund's portfolio securities. The correlation may be distorted by the fact
that the futures market is dominated by short-term traders seeking to profit
from the difference between a contract or security price objective and their
cost of borrowed funds. This would reduce their value for hedging purposes over
a short time period. The correlation may be further distorted since the futures
contracts that are being used to hedge are not based on municipal obligations.
 
    Another risk is that the Fund's manager could be incorrect in its
expectations as to the direction or extent of various interest rate movements or
the time span within which the movements take place. For example, if the Fund
sold futures contracts for the sale of securities in anticipation of an increase
in interest rates, and then interest rates went down instead, causing bond
prices to rise, the Fund would lose money on the sale.
 
    Put and call options on financial futures have similar characteristics as
Exchange-traded options. See below for a further description of options.
 
    In addition to the risks associated in investing in options on securities,
there are particular risks associated with investing in options on futures. In
particular, the ability to establish and close out positions on such options
will be subject to the development and maintenance of a liquid secondary market.
It is not certain that this market will develop.
 
    In order to assure that the Fund is entering into transactions in futures
contracts for hedging purposes as such is defined by the Commodity Futures
Trading Commission either: 1) a substantial majority (i.e., approximately 75%)
of all anticipatory hedge transactions (transactions in which the Fund does not
own at the time of the transaction, but expects to acquire, the securities
underlying the relevant futures contract) involving the purchase of futures
contracts will be completed by the purchase of securities which are the subject
of the hedge or 2) the underlying value of all long positions in futures
contracts will not exceed the total value of a) all short-term debt obligations
held by the Fund; b) cash held by the Fund; c) cash proceeds due to the Fund on
investments within thirty days; d) the margin deposited on the contracts; and e)
any unrealized appreciation in the value of the contracts.
 
    The Fund may not enter into futures contracts or related options thereon if
immediately thereafter the amount committed to margin plus the amount paid for
option premiums exceeds 5% of the value of the Fund's total assets. In instances
involving the purchase of futures contracts by the Fund, the market value of the
futures contract will be deposited in a segregated account of cash and cash
equivalents to collateralize the position and thereby ensure that the use of
such futures is unleveraged. The Fund may not purchase or sell futures contracts
or related options if immediately thereafter more than one-third of its net
assets would be hedged.
 
    MUNICIPAL BOND INDEX FUTURES.  The Fund may utilize municipal bond index
futures contracts and options thereon for hedging purposes. The Fund's
strategies in employing such contracts will be similar to that discussed above
with respect to financial futures and options thereon. A municipal bond index is
a method of reflecting in a single number the market value of many different
municipal bonds and is designed to be representative of the municipal bond
market generally. The index fluctuates in response to changes in the market
values of the bonds included within the index. Unlike futures contracts on
particular financial instruments, transactions in futures on a municipal bond
index will be settled in cash if held until the close of trading in the
contract. However, like any other futures contract, a position in the contract
may be closed out by purchase or sale of an offsetting contract for the same
delivery month prior to expiration of the contract.
 
    OPTIONS.  The Fund may purchase or sell (write) options on debt securities
as a means of achieving additional return or hedging the value of the Fund's
portfolio. The Fund would only buy options listed on national securities
exchanges. The Fund will not purchase options if, as a result, the aggregate
cost of all outstanding options exceeds 10% of the Fund's total assets.
 
                                       16
<PAGE>
    Presently there are no options on California tax-exempt securities traded on
national securities exchanges and until such time as they become available, the
Fund will not invest in options on debt securities. It is anticipated that such
instruments will not become available during the next year.
 
    A call option is a contract that gives the holder of the option the right to
buy from the writer of the call option, in return for a premium, the security
underlying the option at a specified exercise price at any time during the term
of the option. The writer of the call option has the obligation upon exercise of
the option to deliver the underlying security upon payment of the exercise price
during the option period. A put option is a contract that gives the holder of
the option the right to sell to the writer, in return for a premium, the
underlying security at a specified price during the term of the option. The
writer of the put has the obligation to buy the underlying security upon
exercise, at the exercise price during the option period.
 
    The Fund will only write covered call or covered put options. The Fund may
not write covered options in an amount exceeding 20% of the value of its total
assets. A call option is "covered" if the Fund owns the underlying security
subject to the option or has an absolute and immediate right to acquire that
security or futures contract without additional cash consideration (or for
additional cash consideration held in a segregated account by its custodian)
upon conversion or exchange of other securities held in its portfolio. A call
option is also covered if the Fund holds a call on the same security or futures
contract as the call written where the exercise price of the call held is (i)
equal to or less than the exercise price of the call written or (ii) greater
than the exercise price of the call written if the difference is maintained by
the Fund in cash, Treasury bills or other liquid portfolio securities in a
segregated account with its custodian. A put option is "covered" if the Fund
maintains cash, Treasury bills or other liquid portfolio securities with a value
equal to the exercise price in a segregated account with its custodian, or else
holds a put on the same security or futures contract as the put written where
the exercise price of the put held is equal to or greater than the exercise
price of the put written.
 
    If the Fund has written an option, it may terminate its obligation by
effecting a closing purchase transaction. This is accomplished by purchasing an
option of the same series as the option previously written. However, once the
Fund has been assigned an exercise notice, the Fund will be unable to effect a
closing purchase transaction. Similarly, if the Fund is the holder of an option
it may liquidate its position by effecting a closing sale transaction. This is
accomplished by selling an option of the same series as the option previously
purchased. There can be no assurance that either a closing purchase or sale
transaction can be effected when the Fund so desires.
 
    The Fund will realize a profit from a closing transaction if the price of
the transaction is less than the premium received from writing the option or is
more than the premium paid to purchase the option; the Fund will realize a loss
from a closing transaction if the price of the transaction is more than the
premium received from writing the option or is less than the premium paid to
purchase the option. Since call option prices generally reflect increases in the
price of the underlying security, any loss resulting from the repurchase of a
call option may also be wholly or partially offset by unrealized appreciation of
the underlying security. Other principal factors affecting the market value of a
put or a call option include supply and demand, interest rates, the current
market price and price volatility of the underlying security and the time
remaining until the expiration date.
 
    An option position may be closed out only on an exchange which provides a
secondary market for an option of the same series. Although the Fund will
generally purchase or write only those options for which there appears to be an
active secondary market, there is no assurance that a liquid secondary market on
an exchange will exist for any particular option. In such event it might not be
possible to effect closing transactions in particular options, so that the Fund
would have to exercise its options in order to realize any profit and would
incur brokerage commissions upon the exercise of call options and upon the
subsequent disposition of underlying securities for the exercise of put options.
If the Fund as a covered call option writer is unable to effect a closing
purchase transaction in a secondary market, it will not be able to sell the
underlying security until the option expires or it delivers the underlying
security upon exercise.

RISK CONSIDERATIONS RELATING TO CALIFORNIA TAX-EXEMPT SECURITIES
 
    The Trust will be affected by any political, economic or regulatory
developments affecting the ability of California issuers to pay interest or
repay principal on their obligations. Various developments regarding the
California Constitution and State statutes which limit the taxing and spending
authority of California governmental entities may impair the ability of
California issuers to maintain debt service on their obligations. The following
information constitutes only a brief summary and is not intended as a complete
description.
 
    In 1978, Proposition 13, an amendment to the California Constitution, was
approved, limiting real property valuation for property tax purposes and the
power of local governments to increase real property tax revenues and revenues
from other sources. Legislation adopted after Proposition 13 provided for
assistance to local governments, including the redistribution of the
then-existing surplus in the General Fund, reallocation of revenues to local
governments, and assumption by the State of certain local government
obligations. However, more recent legislation reduced such state assistance.
There can be no assurance that any particular level of State aid to local
governments will be maintained in future years. In NORDLINGER V. HAHN, the
United States Supreme Court upheld certain provisions of Proposition 13 against
claims that it violated the equal protection clause of the Constitution.
 
    In 1979, an amendment was passed adding Article XIIIB to the State
Constitution. As amended in 1990, Article XIIIB imposes an "appropriations
limit" on the spending authority of the State and local government entities. In
general, the appropriations limit is based on certain 1978-1979 expenditures,
adjusted annually to reflect changes in the cost of living, population and
certain services provided by State and local government entities.
"Appropriations limit" does not include appropriations for qualified capital
outlay projects, certain increases in transportation-related taxes, and certain
emergency appropriations.
 
    If a government entity raises revenues beyond its "appropriations limit" in
any year, a portion of the excess which cannot be appropriated within the
following year's limit must be returned to the entity's taxpayers within two
subsequent fiscal years, generally by a tax credit, refund or temporary
suspension of tax rates or fee schedules. "Debt service" is excluded from these
limitations, and is defined as "appropriations required to pay the cost of
interest and redemption charges, including the funding of any reserve or sinking
fund required in connection therewith, on indebtedness existing or legally
authorized as of January 1, 1979 or on bonded indebtedness thereafter approved
[by the voters]." In addition, Article XIIIB requires the State Legislature to
establish a prudent State reserve, and to require the transfer of 50% of excess
revenue to the State School Fund; any amounts allocated to the State School Fund
will increase the appropriations limit.
 
    In June 1982, the voters of California passed two initiative measures to
repeal the California gift and inheritance tax laws and to enact, in lieu
thereof, California death taxes. California voters also passed an initiative
measure to increase, for taxable years commencing on or after January 1, 1982,
the amount to account for the effects of inflation. Decreases in State and local
revenues in future fiscal years as a consequence of these initiatives may result
in reductions in allocations of State revenues to California issuers or in the
ability of California issuers to pay their obligations.
 
    In 1986, California voters approved an initiative statute known as
Proposition 62. This initiative (i) requires that any tax for general
governmental purposes imposed by local governments be approved by resolution or
ordinance adopted by a two-thirds vote of the governmental entity's legislative
body and by a majority vote of the electorate of the governmental entity, (ii)
requires that any special tax (defined as tax levied for other than general
governmental purposes) imposed by a local governmental entity be approved by a
two-thirds vote of the voters within that jurisdiction, (iii) restricts the use
of revenues from a special tax to the purposes or for the service for which the
special tax was imposed, (iv) prohibits the imposition of ad valorem taxes on
real property by local governmental entities except as permitted by the
Proposition 13 amendment, (v) prohibits the imposition of transaction taxes and
sales taxes on the sale of real property by local governments, (vi) requires
that any tax imposed by a local government on or after August 1, 1985, be
ratified by a majority vote of the electorate within two years of the adoption
of the
 
                                       18
<PAGE>
initiative or be terminated by November 15, 1989, (vii) requires that, in the
event a local government fails to comply with the provisions of this measure, a
reduction of the amount of property tax revenue allocated to such local
government occurs in an amount equal to the revenues received by such entity
attributable to the tax levied in violation of the initiative, and (viii)
permits these provisions to be amended exclusively by the voters of the State of
California.
 
    In September 1995, the California Supreme Court upheld the constitutionality
of Proposition 62, creating uncertainty as to the legality of certain local
taxes enacted by non-charter cities in California without voter approval. It is
not possible to predict the impact of the decision.
 
    In November 1996, California voters approved Proposition 218. The initiative
applied the provisions of Proposition 62 to all entities, including charter
cities. It requires that all taxes for general purposes obtain a simple majority
popular vote and that taxes for special purposes obtain a two-thirds majority
vote. Prior to the effectiveness of Proposition 218, charter cities could levy
certain taxes such as transient occupancy taxes and utility user's taxes without
a popular vote. Proposition 218 will also limit the authority of local
governments to impose property-related assessments, fees and charges, requiring
that such assessments be limited to the special benefit conferred and
prohibiting their use for general governmental services. Proposition 218 also
allows voters to use their initiative power to reduce or repeal
previously-authorized taxes, assessments, fees and charges.
 
    In 1988, State voters approved Proposition 87, which amended Article XVI of
the State Constitution to authorize the State Legislature to prohibit
redevelopment agencies from receiving any property tax revenues raised by
increased property taxes to repay bonded indebtedness of local government which
is not approved by voters on or before January 1, 1989. It is not possible to
predict whether the State Legislature will enact such a prohibition, nor is it
possible to predict the impact of Proposition 87 on redevelopment agencies and
their ability to make payments on outstanding debt obligations.
 
    In November 1988, California voters approved Proposition 98. This initiative
requires that revenues in excess of amounts permitted to be spent and which
would otherwise be returned by revision of tax rates or fee schedules, be
transferred and allocated (up to a maximum of 40%) to the State School Fund and
be expended solely for purposes of instructional improvement and accountability.
No such transfer or allocation of funds will be required if certain designated
state officials determine that annual student expenditures and class size meet
certain criteria as set forth in Proposition 98. Any funds allocated to the
State School Fund shall cause the appropriation limits to be annually increased
for any such allocation made in the prior year. Proposition 98 also requires the
State of California to provide a minimum level of funding for public schools and
community colleges. The initiative permits the enactment of legislation, by a
two-thirds vote, to suspend the minimum funding requirement for one year.
 
    The State is a party to numerous legal proceedings, many of which normally
occur in governmental operations and if decided against the State, might require
the State to make significant future expenditures or impair future revenue
sources.
 
    On December 6, 1994, Orange County (California) became the largest
municipality in the United States to file for protection under the Federal
bankruptcy laws. The filing stemmed from approximately $1.7 billion in losses
suffered by the County's investment pool due to investments in high risk
"derivative" securities. On June 12, 1996, it emerged from bankruptcy after the
successful sale of $880 million in municipal bonds allowed the county to pay off
the last of its creditors. On January 7, 1997, Orange County returned to the
municipal bond market with a $136 million bond issue maturing in 13 years at an
insured yield of 7.23%.
 
    Los Angeles County, the nation's largest county, is also experiencing
financial difficulty. In August 1995 the credit rating of the county's long-term
bonds was downgraded for the third time since 1992 as a result of, among other
things, severe operating deficits for the county's health care system. Also, the
county has not yet recovered from the ongoing loss of revenue caused by state
property tax shift
 
                                       19
<PAGE>
initiatives in 1993 through 1995. Entering the 1996-1997 fiscal year, the county
faced a budgetary shortfall of approximately $516 million. The county's
budgetary difficulties have continued with their effect on the 1997-1998 budget
still uncertain.
 
    The effect of these various constitutional and statutory amendments and
budget developments upon the ability of California issuers to pay interest and
principal on their obligations remains unclear and in any event may depend upon
whether a particular California tax-exempt security is a general or limited
obligation bond and on the type of security provided for the bond. It is
possible that other measures affecting the taxing or spending authority of
California or its political subdivisions may be approved or enacted in the
future.
 
PORTFOLIO MANAGEMENT
 
    The Fund's portfolio turnover rate during the fiscal year ended December 31,
1996 was 11%. It is anticipated that the Fund's portfolio turnover rate will not
exceed 50% during the fiscal year ending December 31, 1997. A 50% turnover rate
would occur, for example, if 50% 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. However, the Fund may engage in
short-term trading consistent with its investment objective. Securities may be
sold in anticipation of a market decline (a rise in interest rates) or purchased
in anticipation of a market rise (a decline in interest rates). In addition, a
security may be sold and another security of comparable quality purchased at
approximately the same time to take advantage of what the Investment Manager
believes to be a temporary disparity in the normal yield relationship between
the two securities. These yield disparities may occur for reasons not directly
related to the investment quality of particular issues or the general movement
of interest rates, such as changes in the overall demand for, or supply of,
various types of tax-exempt securities.
 
    In general, purchases and sales may also be made to restructure the
portfolio in terms of average maturity, quality, coupon yield, or
diversification for any one or more of the following purposes: (a) to increase
income, (b) to improve portfolio quality, (c) to minimize capital depreciation,
(d) to realize gains or losses, or for such other reasons as the Investment
Manager deems relevant in light of economic and market conditions.
 
    The Fund does not generally intend to invest more than 25% of its total
assets in securities of any one governmental unit. Subject to investment
restriction number 3 in the Prospectus, the Fund may invest more than 25% of its
total assets in industrial development and pollution control bonds (two kinds of
tax-exempt Municipal Bonds).
 
    The Fund may invest in obligations customarily sold to institutional
investors in private transactions with the issuers thereof and up to 5% of its
total assets in securities for which a BONA FIDE market does not exist at the
time of purchase. With respect to any securities as to which a BONA FIDE market
does not exist, the Fund may be unable to dispose of such securities promptly at
reasonable prices. It is the Fund's current intention not to invest in such
obligations.
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    In addition to the investment restrictions enumerated in the Prospectus, the
investment restrictions listed below have been adopted by the Fund as
fundamental policies, which may not be changed without the vote of a majority of
the outstanding voting securities of the Fund, as defined in the Act. Such a
majority is defined as the lesser of (a) 67% of the shares present at a meeting
of shareholders, if the holders of more than 50% of the outstanding shares of
the Fund are present or represented by proxy or (b) more than 50% of the
outstanding shares of the Fund. For purposes of the following restrictions and
those recited in the Prospectus: (a) an "issuer" of a security is the entity
whose assets and revenues are committed to the payment of interest and principal
on that particular security, provided that the securities guaranteed by separate
entities will be considered a separate security; (b) a "taxable security" is any
security the interest on which is subject to federal income tax; and (c) all
percentage limitations apply
 
                                       20
<PAGE>
immediately after a purchase or initial investment, and any subsequent change in
any applicable percentage resulting from market fluctuations or other changes in
total or net assets does not require elimination of any security from the
portfolio.
 
    The Fund may not:
 
         1. Invest in common stock.
 
         2. Invest in securities of any issuer if, to the knowledge of the Fund,
    any officer or trustee of the Fund or any officer or director of the
    Investment Manager owns more than 1/2 of 1% of the outstanding securities of
    such issuer, and such officers, trustees and directors who own more than 1/2
    of 1% own in the aggregate more than 5% of the outstanding securities of
    such issuer.
 
         3. Purchase or sell real estate or interests therein, although it may
    purchase securities secured by real estate or interests therein.
 
         4. Purchase or sell commodities except that the Fund may purchase
    financial futures contracts and related options in accordance with
    procedures adopted by the Trustees described in its Prospectus and Statement
    of Additional Information.
 
         5. Purchase oil, gas or other mineral leases, rights or royalty
    contracts, or exploration or development programs.
 
         6. Write, purchase or sell puts, calls, or combinations thereof except
    options on futures contracts or options on debt securities.
 
         7. Purchase securities of other investment companies, except in
    connection with a merger, consolidation, reorganization or acquisition of
    assets.
 
         8. 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 the value of its total assets (not
    including the amount borrowed).
 
         9. Pledge its assets or assign or otherwise encumber them except to
    secure permitted borrowings. (For the purpose of this restriction,
    collateral arrangements with respect to the writing of options and
    collateral arrangements with respect to initial margin for futures are not
    deemed to be pledges of assets and neither such arrangements nor the
    purchase or sale of futures are deemed to be the issuance of a senior
    security as set forth in restriction 10.)
 
        10. Issue senior securities as defined in the Act except insofar as the
    Fund may be deemed to have issued a senior security by reason of: (a)
    entering into any repurchase agreement; (b) purchasing any securities on a
    when-issued or delayed delivery basis; or (c) borrowing money in accordance
    with restrictions described above.
 
        11. Make loans of money or securities, except: (a) by the purchase of
    debt obligations in which the Fund may invest consistent with its investment
    objective and policies; (b) by investment in repurchase agreements; and (c)
    by lending its portfolio securities.
 
        12. Make short sales of securities.
 
        13. Purchase securities on margin, except for such short-term loans as
    are necessary for the clearance of purchases 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.
 
        14. 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.
 
        15. Invest for the purpose of exercising control or management of any
    other issuer.
 
                                       21
<PAGE>
   
    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
- --------------------------------------------------------------------------------
 
    The Investment Manager is responsible for decisions to buy and sell
securities and commodities for the Fund, the selection of brokers and dealers to
effect the transactions, and the negotiation of brokerage commissions, if any.
The Fund expects that the primary market for the securities in which it intends
to invest will generally be the over-the-counter market. Securities are
generally traded in the over-the-counter market on a "net" basis with dealers
acting as principal for their own accounts without charging a stated commission,
although the price of the security usually includes a profit to the dealer.
Options and futures transactions will usually be effected through a broker and a
commission will be charged. The Fund also expects that securities will be
purchased at times in underwritten offerings where the price includes a fixed
amount of compensation, generally referred to as the underwriter's concession or
discount. On occasion, the Fund may also purchase certain money market
instruments directly from an issuer, in which case no commissions or discounts
are paid. During the fiscal years ended December 31, 1994, 1995 and 1996, the
Fund did not pay any 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 are 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 be given to obtaining the most
favorable prices and efficient execution of transactions. In seeking to
implement the Fund's policies, the Investment Manager effects transactions with
those brokers and dealers who the Investment Manager believes provide the most
favorable prices and are capable of providing efficient executions. If the
Investment Manager believes such price 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 every case, 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 Fund will not reduce the management fee it
pays to the Investment Manager 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
 
                                       22
<PAGE>
   
DWR only when the price available from DWR is better than that available from
other dealers. During the fiscal years ended December 31, 1994, 1995 and 1996,
the Fund did not effect any principal transactions with DWR.
    
 
   
    Consistent with the policy described above, brokerage transactions in
securities and commodities listed on exchanges or admitted to unlisted trading
privileges may be effected through DWR and other affiliated brokers and dealers.
In order for an affiliated broker or dealer to effect portfolio transactions for
the Fund, the commissions, fees or other remuneration received by the affiliated
broker or dealer must be reasonable and fair compared to the commissions, fees
or other remuneration paid to other brokers in connection with comparable
transactions involving similar securities being purchased or sold on an exchange
during a comparable period of time. This standard would allow the affiliated
broker or dealer to receive no more than the remuneration which would be
expected to be received by an unaffiliated broker in a commensurate arms-length
transaction. Furthermore, the Trustees of the Fund, including a majority of the
Trustees who are not "interested" Trustees, 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 DISTRIBUTOR
- --------------------------------------------------------------------------------
 
   
    As discussed in the Prospectus, shares of the Fund are distributed by Dean
Witter Distributors Inc. (the "Distributor"), on a continuous basis. 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
dealers. The Distributor, a Delaware corporation, is a wholly-owned subsidiary
of MSDWD. The Trustees, 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 Board.
    
 
   
    The Distributor bears all expenses it may incur in providing services under
the Distribution Agreement. Such expenses include the payment of commissions for
sales of the Fund's shares and incentive compensation to account executives. The
Distributor also pays certain expenses in connection with the distribution of
the Fund's shares, including the costs of preparing, printing and distributing
advertising or promotional materials, and the costs of printing and distributing
prospectuses and supplements thereto used in connection with the offering and
sale of the Fund's shares. The Fund bears the costs of initial typesetting,
printing and distribution of prospectuses and supplements thereto to
shareholders. The Fund also bears the costs of registering the Fund and its
shares under federal securities laws and pays filing fees in accordance with
state securities laws. The Fund and the Distributor have agreed to indemnify
each other against certain liabilities, including liabilities under the
Securities Act of 1933, as amended. Under the Distribution Agreement, the
Distributor uses its best efforts in rendering services to the Fund, but in the
absence of willful misfeasance, bad faith, gross negligence or reckless
disregard of its obligations, the Distributor is not liable to the Fund or any
of its shareholders for any error of judgment or mistake of law or for any act
or omission or for losses sustained by the Fund or its shareholders.
    
 
   
PLAN OF DISTRIBUTION
    
 
   
    The Fund has adopted a Plan of Distribution pursuant to Rule 12b-1 under the
Act (the "Plan") pursuant to which each Class, other than Class D, pays the
Distributor compensation accrued daily and payable monthly at the following
annual rates: 0.25% and 0.75% of the average daily net assets of Class A and
Class C, respectively, and, with respect to Class B, 0.75% 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
    
 
                                       23
<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 $1,752,000, $1,540,000 and $1,325,000 in contingent
deferred sales charges for the fiscal years ended December 31, 1994, 1995 and
1996, respectively.
    
 
   
    The Distributor has informed the Fund that the entire fee payable by Class A
and a portion of the fees payable by each of Class B and Class C each year
pursuant to the Plan equal to 0.20% of the average daily net assets of Class B
and 0.25% of the average daily net assets of Class C are currently each
characterized as a "service fee" under the Rules of the Association of the
National Association of Securities Dealers, Inc. (of which the Distributor is a
member). The "service fee" is a payment made for personal service and/or the
maintenance of shareholder accounts. The remaining portion of the Plan fees
payable by a Class, if any, is characterized as an "asset-based sales charge" as
such is defined by the aforementioned Rules of the Association.
    
 
   
    The Plan was adopted by a majority vote of the Board of Trustees, including
all 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"), cast in person at a
meeting called for the purpose of voting on the Plan, on June 13, 1984, by the
then sole shareholder of the Fund on June 26, 1984 and by the shareholders
holding a majority, as defined in the Act, of the outstanding voting securities
of the Fund at a Special Meeting of Shareholders of the Fund held on October 21,
1985.
    
 
   
    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, 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 October 26, 1995, the Trustees of the
Fund, including all of the Independent 12b-1 Trustees, approved an amendment to
the Plan to permit payments to be made under the Plan with respect to certain
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. 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 receive and
review promptly after the end of each calendar quarter a written report provided
by the Distributor of the amounts expended under the Plan and the purpose for
which such expenditures were made. The Fund accrued amounts payable to the
Distributor under the Plan, during the fiscal year ended December 31, 1996, of
$7,504,744. This amount is equal to 0.75% of the Fund's average daily net assets
for the fiscal year and was calculated pursuant to clause (b) 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.
    
 
                                       24
<PAGE>
   
    The Plan was adopted in order to permit the implementation of the Fund's
method of distribution. Under this distribution method the Fund offers four
Classes of shares, each with a different distribution arrangement as set forth
in the Prospectus.
    
 
   
    With respect to Class A shares, DWR compensates its account executives by
paying them, from proceeds of the front-end sales charge, commissions for the
sale of Class A shares, currently a gross sales credit of up to 4.0% of the
amount sold (except as provided in the following sentence) and an annual
residual commission, currently a residual of up to 0.20% of the current value of
the respective accounts for which they are the account executives or dealers of
record in all cases. On orders of $1 million or more (for which no sales charge
was paid), the Investment Manager compensates DWR's account executives by paying
them, from its own funds, a gross sales credit of 1.0% of the amount sold.
    
 
   
    With respect to Class B shares, DWR compensates its account executives by
paying them, from its own funds, commissions for the sale of Class B shares,
currently a gross sales credit of up to 4.0% of the amount sold and an annual
residual commission, currently a residual of up to 0.20% of the current value
(not including reinvested dividends or distributions) of the amount sold in all
cases.
    
 
   
    With respect to Class C shares, DWR compensates its account executives by
paying them, from its own funds, commissions for the sale of Class C shares,
currently a gross sales credit of up to 1.0% of the amount sold and an annual
residual commission, currently a residual of up to 0.75% of the current value of
the respective accounts for which they are the account executives of record.
    
 
   
    With respect to Class D shares other than shares held by participants in
InterCapital's mutual fund asset allocation program, the Investment Manager
compensates DWR's account executives by paying them, from its own funds,
commissions for the sale of Class D shares, currently a gross sales credit of up
to 1.0% of the amount sold. There is a chargeback of 100% of the amount paid if
the Class D shares are redeemed in the first year and a chargeback of 50% of the
amount paid if the Class D shares are redeemed in the second year after
purchase. The Investment Manager also compensates DWR's account executives by
paying them, from its own funds, an annual residual commission, currently a
residual of up to 0.10% of the current value of the respective accounts for
which they are the account executives of record (not including accounts of
participants in the InterCapital mutual fund asset allocation program).
    
 
   
    The gross sales credit is a charge which reflects commissions paid by DWR to
its account executives and DWR's Fund-associated distribution-related expenses,
including sales compensation, and overhead and other branch office
distribution-related expenses including (a) the expenses of operating DWR's
branch offices in connection with the sale of Fund shares, including lease
costs, the salaries and employee benefits of operations and sales support
personnel, utility costs, communications costs and the costs of stationery and
supplies, (b) the costs of client sales seminars, (c) travel expenses of mutual
fund sales coordinators to promote the sale of Fund shares and (d) other
expenses relating to branch promotion of Fund sales. The distribution fee that
the Distributor receives from the Fund under the Plan, in effect, offsets
distribution expenses incurred under the Plan on behalf of the Fund and, in the
case of Class B shares, opportunity costs, such as the gross sales credit and an
assumed interest charge thereon ("carrying charge"). In the Distributor's
reporting of the distribution expenses to the Fund, in the case of Class B
shares, such assumed interest (computed at the "broker's call rate") has been
calculated on the gross credit as it is reduced by amounts received by the
Distributor under the Plan and any contingent deferred sales charges received by
the Distributor upon redemption of shares of the Fund. No other interest charge
is included as a distribution expense in the Distributor's calculation of its
distribution costs for this purpose. The broker's call rate is the interest rate
charged to securities brokers on loans secured by exchange-listed securities.
    
 
   
    The Fund paid 100% of the $7,504,744 accrued under the Plan for the fiscal
year ended December 31, 1996 to the Distributor. The Distributor and DWR
estimate that they have spent, pursuant to the Plan, $77,479,304 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) 3.91% ($3,028,056)--advertising
and promotional
    
 
                                       25
<PAGE>
   
expenses; (ii) 0.33% ($257,196)--printing of prospectuses for distribution to
other than current shareholders; and (iii) 95.76% ($74,194,052)--other expenses,
including the gross sales credit and the carrying charge, of which 8.25%
($6,118,724) represents carrying charges, 36.99% ($27,447,972) represents
commission credits to DWR branch offices for payments of commissions to account
executives and 54.76% ($40,627,356) represents overhead and other branch office
distribution-related expenses. 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 0.75%, 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 of distributing shares of the Fund may be
more or less than the total of (i) the payments made by the Fund pursuant to the
Plan and (ii) the proceeds of contingent deferred sales charges paid by
investors upon redemption of shares. The Distributor has advised the Fund that
in the case of Class B shares, the excess distribution expenses, including the
carrying charge designed to approximate the opportunity costs incurred by DWR
which arise from it having advanced monies without having received the amount of
any sales charges imposed at the time of sale of the Fund's Class B shares,
totalled $3,649,503, which was equal to 0.37% of the net assets of the Fund as
of December 31, 1996. Because there is no requirement under the Plan that the
Distributor be reimbursed for all distribution expenses with respect to Class B
shares or any requirement that the Plan be continued from year to year, this
excess amount does not constitute a liability of the Fund. Although there is no
legal obligation for the Fund to pay expenses incurred in excess of payments
made to the Distributor under the Plan and the proceeds of contingent deferred
sales charges paid by investors upon redemption of shares, if for any reason the
Plan is terminated, the Trustees will consider at that time the manner in which
to treat such expenses. Any cumulative expenses incurred, but not yet recovered
through distribution fees or contingent deferred sales charges, may or may not
be recovered through future distribution fees or contingent deferred sales
charges.
    
 
   
    No interested person of the Fund nor any Trustee of the Fund who is not an
interested person of the Fund, as defined in the Act, has any direct 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 December 31, 1984 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 continuance of the Plan for one year,
until April 30, 1998,
    
 
                                       26
<PAGE>
   
was approved by the Board of Trustees of the Fund, including a majority of the
Independent 12b-1 Trustees, at a Board meeting held on April 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 by the shareholders of the
affected Class or Classes of the Fund, and all material amendments to the Plan
must also be approved by the 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 12b-1 Trustees
shall be committed to the discretion of the Independent 12b-1 Trustees.
    
 
   
DETERMINATION OF NET ASSET VALUE
    
- --------------------------------------------------------------------------------
 
    As discussed in the Prospectus, portfolio securities (other than short-term
debt securities and futures and options) are valued for the Fund by an outside
independent pricing service approved by the Board of Trustees. The pricing
service has informed the Fund that in valuing the Fund's portfolio securities it
uses both a computerized grid matrix of tax-exempt securities and evaluations by
its staff, in each case based on information concerning market transactions and
quotations from dealers which reflect the bid side of the market each day. The
Fund's portfolio securities are thus valued by reference to a combination of
transactions and quotations for the same or other securities believed to be
comparable in quality, coupon, maturity, type of issue, call provisions, trading
characteristics and other features deemed to be relevant. The Board of Trustees
believes that timely and reliable market quotations are generally not readily
available to the Fund for purposes of valuing tax-exempt securities and that the
valuations supplied by the pricing service, using the procedures outlined above
and subject to periodic review, are more likely to approximate the fair value of
such securities.
 
    The Investment Manager will periodically review and evaluate the procedures,
methods and quality of services provided by the pricing service then being used
by the Fund and may, from time to time, recommend to the Board of Trustees the
use of other pricing services or discontinuance of the use of any pricing
service in whole or part. The Board may determine to approve such recommendation
or to make other provisions for pricing of the Fund's portfolio securities.
Short-term taxable debt securities with sixty days or less remaining to maturity
at time of purchase are valued at amortized cost, unless the Board determines
such does not reflect the securities' fair value, in which case these securities
will be valued at their fair value as determined by the Board of Trustees. Other
short-term taxable debt securities will be valued on a mark to market basis
until such time as they have 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' fair value, in which
case these securities will be valued at their fair market value as determined by
the Trustees. Listed options on debt securities are valued at the latest sale
price on the exchange on which they are listed unless no sales of such options
have taken place that day, in which case they will be valued at the mean between
their closing bid and asked prices. Unlisted options on debt securities are
valued at the mean between the latest bid and asked price. Futures contracts and
options thereon which are traded on commodities exchanges are valued at their
last sale price on such commodities exchanges unless the Trustees determine that
such price does not
 
                                       27
<PAGE>
reflect their market value, in which case they will be valued at their fair
value as determined by the Trustees. All other securities, including illiquid
securities, and other assets are valued at their fair value as determined in
good faith under procedures established by and under the supervision of the
Board of Trustees.
 
   
    As stated in the Prospectus, the net asset value for each Class of shares of
the Fund will be computed once daily at 4:00 P.M., New York time (or, on days
when the New York Stock Exchange closes prior to 4:00 P.M., at such earlier
time), on each day that the New York Stock Exchange is open. The New York Stock
Exchange currently observes the following holidays: New Year's Day; Presidents'
Day; Reverend Dr. Martin Luther King, Jr. Day; Good Friday; Memorial Day;
Independence Day; Labor Day; Thanksgiving Day; and Christmas Day.
    
 
   
PURCHASE OF FUND SHARES
    
- --------------------------------------------------------------------------------
 
   
    As discussed in the Prospectus, the Fund offers four Classes of shares as
follows:
    
 
   
INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES
    
 
   
    Class A shares are sold to investors with an initial sales charge that
declines to zero for larger purchases; however, Class A shares sold without an
initial sales charge are subject to a contingent deferred sales charge ("CDSC")
of 1.0% if redeemed within one year of purchase, except in the circumstances
discussed in the Prospectus.
    
 
   
    RIGHT OF ACCUMULATION.  As discussed in the Prospectus, investors may
combine the current value of shares purchased in separate transactions for
purposes of benefitting from the reduced sales charges available for purchases
of shares of the Fund totalling at least $25,000 in net asset value. For
example, if any person or entity who qualifies for this privilege holds Class A
shares of the Fund and/or other Dean Witter Funds that are multiple class funds
("Dean Witter Multi-Class Funds") or shares of other Dean Witter Funds sold with
a front-end sales charge purchased at a price including a front-end sales charge
having a current value of $5,000, and purchases $20,000 of additional shares of
the Fund, the sales charge applicable to the $20,000 purchase would be 4.0% of
the offering price.
    
 
   
    The Distributor must be notified by the selected broker-dealer or the
shareholder at the time a purchase order is placed that the purchase qualifies
for the reduced charge under the Right of Accumulation. Similar notification
must be made in writing by the selected broker-dealer or shareholder when such
an order is placed by mail. The reduced sales charge will not be granted if: (a)
such notification is not furnished at the time of the order; or (b) a review of
the records of the Distributor or Dean Witter Trust Company (the "Transfer
Agent") fails to confirm the investor's represented holdings.
    
 
   
    LETTER OF INTENT.  As discussed in the Prospectus, reduced sales charges are
available to investors who enter into a written Letter of Intent providing for
the purchase, within a thirteen-month period, of Class A shares of the Fund from
the Distributor or from a single Selected Broker-Dealer.
    
 
   
    A Letter of Intent permits an investor to establish a total investment goal
to be achieved by any number of purchases over a thirteen-month period. Each
purchase of Class A shares made during the period will receive the reduced sales
commission applicable to the amount represented by the goal, as if it were a
single purchase. A number of shares equal in value to 5% of the dollar amount of
the Letter of Intent will be held in escrow by the Transfer Agent, in the name
of the shareholder. The initial purchase under a Letter of Intent must be equal
to at least 5% of the stated investment goal.
    
 
   
    The Letter of Intent does not obligate the investor to purchase, nor the
Fund to sell, the indicated amount. In the event the Letter of Intent goal is
not achieved within the thirteen-month period, the investor is required to pay
the difference between the sales charge otherwise applicable to the purchases
made during this period and sales charges actually paid. Such payment may be
made directly to the Distributor or, if not paid, the Distributor is authorized
by the shareholder to liquidate a sufficient number of his or her escrowed
shares to obtain such difference.
    
 
                                       28
<PAGE>
   
    If the goal is exceeded and purchases pass the next sales charge level, the
sales charge on the entire amount of the purchase that results in passing that
level and on subsequent purchases will be subject to further reduced sales
charges in the same manner as set forth above under "Right of Accumulation," but
there will be no retroactive reduction of sales charges on previous purchases.
For the purpose of determining whether the investor is entitled to a further
reduced sales charge applicable to purchases at or above a sales charge level
which exceeds the stated goal of a Letter of Intent, the cumulative current net
asset value of any shares owned by the investor in any other Dean Witter Funds
held by the shareholder which were previously purchased at a price including a
front-end sales charge (including shares of the Fund and other Dean Witter Funds
acquired in exchange for those shares, and including in each case shares
acquired through reinvestment of dividends and distributions) will be added to
the cost or net asset value of shares of the Fund owned by the investor.
However, shares of "Exchange Funds" (see "Shareholder Services--Exchange
Privilege") and the purchase of shares of other Dean Witter Funds will not be
included in determining whether the stated goal of a Letter of Intent has been
reached.
    
 
   
    At any time while a Letter of Intent is in effect, a shareholder may, by
written notice to the Distributor, increase the amount of the stated goal. In
that event, only shares purchased during the previous 90-day period and still
owned by the shareholder will be included in the new sales charge reduction. The
5% escrow and minimum purchase requirements will be applicable to the new stated
goal. Investors electing to purchase shares of the Fund pursuant to a Letter of
Intent should carefully read such Letter of Intent.
    
 
   
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. 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 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 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 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 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 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
    
 
                                       29
<PAGE>
   
purposes of determining the number of years from the time of any payment for the
purchase of shares, all payments made during a month will be aggregated and
deemed to have been made on the last day of the month. The following table sets
forth the rates of the CDSC applicable to Class B shares of the Fund:
    
 
   
<TABLE>
<CAPTION>
                                             YEAR SINCE                                                  CDSC AS A

                                            PAYMENT MADE                                              AMOUNT REDEEMED
- ----------------------------------------------------------------------------------------------------  ----------------
<S>                                                                                                   <C>
First...............................................................................................        5.0%

Fourth..............................................................................................        2.0%
Fifth...............................................................................................        2.0%
Sixth...............................................................................................        1.0%
Seventh and thereafter..............................................................................        None
</TABLE>
    
 
   
    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 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 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 statement
reflecting the status of such Account.
    
 
   
    AUTOMATIC INVESTMENT OF DIVIDENDS AND DISTRIBUTIONS.  As stated in the
Prospectus, all income dividends and capital gains distributions are
automatically paid in full and fractional shares of the applicable Class of the
Fund, unless the shareholder requests that they be paid in cash. Each purchase
of shares of the Fund is made upon the condition that the Transfer Agent is
thereby automatically appointed as agent of the investor to receive all
dividends and capital gains distributions on shares owned by the investor. Such
dividends and distributions will be paid, at the net asset value per share, in
shares of the applicable Class of the Fund (or in cash if the shareholder so
requests) as of the close of business on the monthly payment date, as stated in
the Prospectus. 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 payment date of the dividend or the record date of
the distribution. In the case of recently purchased shares for which
registration instructions have not been received on the payment or record date,
cash payments will be made to DWR or other selected broker-dealer, and will be
forwarded to the shareholder, upon the receipt of proper instructions.
    
 
                                       30
<PAGE>
   
    TARGETED DIVIDENDS-SM-  In states where it is legally permissible,
shareholders may also have all income dividends and capital gains distributions
automatically invested in shares of any Class of an open-end Dean Witter Fund
other than Dean Witter California Tax-Free Income Fund or in another Class of
Dean Witter California Tax-Free Income Fund. Such investment will be made as
described above for automatic investment in shares of the applicable Class of
the Fund, at the net asset value per share of the selected 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.  Any shareholder
who receives a cash payment representing a dividend or capital gains
distribution may invest such dividend or distribution in shares of the
applicable Class at net asset value, without the imposition of a CDSC upon
redemption, by returning the check or the proceeds to the Transfer Agent within
30 days after the payment date. If the shareholder returns the proceeds of a
dividend or distribution, such funds must be accompanied by a signed statement
indicating that the proceeds constitute a dividend or distribution to be
invested. Such investment will be made at the net asset value per share next
determined after receipt of the check or proceeds by the Transfer Agent.
    
 
   
    DIRECT INVESTMENTS THROUGH TRANSFER AGENT.  As discussed in the Prospectus,
a shareholder may make additional investments in any Class of shares of the Fund
for which they qualify at any time through the Shareholder Investment Account by
sending a check in any amount, not less than $100, payable to Dean Witter
California Tax-Free Income Fund, and indicating the selected Class, directly to
the Fund's Transfer Agent. In the case of Class A shares, after deduction of any
applicable sales charge, the balance will be applied to the purchase of Fund
shares, and, in the case of shares of the other Classes, the entire amount will
be applied to the purchase of Fund shares, at the net asset value per share next
computed after receipt of the check or purchase payment by the Transfer Agent.
The shares so purchased will be credited to the investor's account.
    
 
   
    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"). 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 dollar amount.
    
 
    The Transfer Agent acts as agent for the shareholder in tendering to the
Fund for redemption sufficient full and fractional shares to provide the amount
of the periodic withdrawal payment designated in the application. The shares
will be redeemed at their net asset value determined, at the shareholder's
option, on the tenth or twenty-fifth day (or next following business day) of the
relevant month or quarter
 
                                       31
<PAGE>
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 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 the sales charges which may be applicable
to purchases or redemptions of shares (see "Purchases 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 DWR or other selected broker-dealer 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.
 
   
EXCHANGE PRIVILEGE
    
 
   
    As discussed in the Prospectus, the Fund makes available to its shareholders
an Exchange Privilege whereby shareholders of each Class of shares of the Fund
may exchange their shares for shares of the same Class of shares of any other
Dean Witter Multi-Class Fund without the imposition of any exchange fee. Shares
may also be exchanged for shares of any of the following funds: Dean Witter
Short-Term U.S. Treasury Trust, Dean Witter Limited Term Municipal Trust, Dean
Witter Short-Term Bond Fund, Dean Witter Intermediate Term U.S. Treasury Trust
and five Dean Witter Funds which are money market funds (the foregoing nine
funds are hereinafter referred to as the "Exchange Funds"). Class A shares may
also be exchanged for shares of Dean Witter Multi-State Municipal Series Trust
and Dean Witter Hawaii Municipal Trust, which are Dean Witter Funds sold with a
front-end sales charge ("FSC Funds"). Class B shares may also be exchanged for
shares of Dean Witter Global Short-Term Income Fund Inc., Dean Witter High
Income Securities and Dean Witter National Municipal Trust, which are Dean
Witter Funds offered with a CDSC ("CDSC Funds"). Exchanges may be made after the
shares of the Fund acquired by purchase (not by exchange or dividend
reinvestment) have been held for thirty days. There is no waiting period for
exchanges of shares acquired by exchange or dividend reinvestment. An exchange
will be treated for federal income tax purposes the same as a repurchase or
redemption of shares, on which the shareholder may realize a capital gain or
loss.
    
 
   
    Any new account established through the Exchange Privilege will have the
same registration and cash dividend or dividend reinvestment plan as the present
account, unless the Transfer Agent receives written notification to the
contrary. For telephone exchanges, the exact registration of the existing
account and the account number must be provided.
    
 
   
    Any shares held in certificate form cannot be exchanged but must be
forwarded to the Transfer Agent and deposited into the shareholder's account
before being eligible for exchange. (Certificates mailed in for deposit should
not be endorsed.)

    As described below, and in the Prospectus under the caption "Purchase of
Fund Shares," a CDSC may be imposed upon a redemption, depending on a number of
factors, including the number of years from the time of purchase until the time
of redemption or exchange ("holding period"). When shares of a Dean Witter
Multi-Class Fund or any CDSC Fund are exchanged for shares of an Exchange Fund,
the exchange is executed at no charge to the shareholder, without the imposition
of the CDSC at the time of the exchange. During the period of time the
shareholder remains in the Exchange Fund (calculated from the last day of the
month in which the Exchange Fund shares were acquired), the holding period or
"year since purchase payment made" is frozen. When shares are redeemed out of
the Exchange Fund, they will be subject to a CDSC which would be based upon the
period of time the shareholder held shares in a Dean Witter Multi-Class Fund or
in a CDSC Fund. However, in the case of shares exchanged into an Exchange Fund
on or after April 23, 1990, upon a redemption of shares which results in a CDSC
being imposed, a credit (not to exceed the amount of the CDSC) will be given in
an amount equal to the Exchange Fund 12b-1 distribution fees incurred on or
after that date which are attributable to those shares. Shareholders acquiring
shares of an Exchange Fund pursuant to this exchange privilege may exchange
those shares back into a Dean Witter Multi-Class Fund or a CDSC Fund from the
Exchange Fund, with no CDSC being imposed on such exchange. The holding period
previously frozen when shares were first exchanged for shares of the Exchange
Fund resumes on the last day of the month in which shares of a Dean Witter
Multi-Class Fund or of a CDSC Fund are reacquired. A CDSC is imposed only upon
an ultimate redemption, based upon the time (calculated as described above) the
shareholder was invested in a Dean Witter Multi-Class Fund or in a CDSC Fund. In
the case of exchanges of Class A shares which are subject to a CDSC, the holding
period also includes the time (calculated as described above) the shareholder
was invested in a FSC Fund.
    
 
   
    When shares initially purchased in a Dean Witter Multi-Class Fund or in a
CDSC Fund are exchanged for shares of a Dean Witter Multi-Class Fund, shares of
a CDSC Fund, shares of a FSC Fund, or shares of an Exchange Fund, the date of
purchase of the shares of the fund exchanged into, for purposes of the CDSC upon
redemption, will be the last day of the month in which the shares being
exchanged were originally purchased. In allocating the purchase payments between
funds for purposes of the CDSC, the amount which represents the current net
asset value of shares at the time of the exchange which were (i) purchased more
than one, three or six years (depending on the CDSC schedule applicable to the
shares) prior to the exchange, (ii) originally acquired through reinvestment of
dividends or distributions and (iii) acquired in exchange for shares of FSC
Funds, or for shares of other Dean Witter Funds for which shares of FSC Funds
have been exchanged (all such shares called "Free Shares"), will be exchanged
first. After an exchange, all dividends earned on shares in an Exchange Fund
will be considered Free Shares. If the exchanged amount exceeds the value of
such Free Shares, an exchange is made, on a block-by-block basis, of non-Free
Shares held for the longest period of time (except that, with respect to Class B
shares, if shares held for identical periods of time but subject to different
CDSC schedules are held in the same Exchange Privilege account, the shares of
that block that are subject to a lower CDSC rate will be exchanged prior to the
shares of that block that are subject to a higher CDSC rate). Shares equal to
any appreciation in the value of non-Free Shares exchanged will be treated as
Free Shares, and the amount of the purchase payments for the non-Free Shares of
the fund exchanged into will be equal to the lesser of (a) the purchase payments
for, or (b) the current net asset value of, the exchanged non-Free Shares. If an
exchange between funds would result in exchange of only part of a particular
block of non-Free Shares, then shares equal to any appreciation in the value of
the block (up to the amount of the exchange) will be treated as Free Shares and
exchanged first, and the purchase payment for that block will be allocated on a
pro rata basis between the non-Free Shares of that block to be retained and the
non-Free Shares to be exchanged. The prorated amount of such purchase payment
attributable to the retained non-Free Shares will remain as the purchase payment
for such shares, and the amount of purchase payment for the exchanged non-Free
Shares will be equal to the lesser of (a) the prorated amount of the purchase
payment for, or (b) the current net asset value of, those exchanged non-Free
Shares. Based upon the procedures described in the Prospectus under the
    
 
                                       33
<PAGE>
   
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, in 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, in its discretion, may accept initial purchases of as low as
$5,000. The minimum initial investment for the Exchange Privilege account of
each Class is $5,000 for 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
whichshares of the Fund have been exchanged, upon such notice as may be required
by applicable regulatory agencies (presently sixty days' prior written notice
for termination or material revision), provided that six months' prior written
notice of termination will be given to the shareholders who hold shares of
Exchange Funds pursuant to the Exchange Privilege, and provided further that the
Exchange Privilege may be terminated or materially revised without notice at
times (a) when the New York Stock Exchange is closed for other than customary
weekends and holidays, (b) when trading on that Exchange is restricted, (c) when
an emergency exists as a result of which disposal by the Fund of securities
owned by it is not reasonably practicable or it is not reasonably practicable
for the Fund fairly to determine the value of its net assets, (d) during any
other period when the Securities and Exchange Commission by order so permits
(provided that applicable rules and regulations of the Securities and Exchange
Commission shall govern as to whether the conditions prescribed in (b) or (c)
exist) or (e) if the Fund would be unable to invest amounts effectively in
accordance with its investment objective, policies and restrictions.
    
 
   
    For further information regarding the Exchange Privilege, shareholders
should contact their 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 acceptable to the Transfer Agent (shareholders should contact the
Transfer Agent for a determination as to whether a particular institution is
such an eligible guarantor). A stock power may be obtained from any dealer or
commercial bank. The Fund may change the signature guarantee requirements from
time to time upon notice to shareholders, which may be by means of a supplement
to the prospectus or a revised prospectus.
 
   
    REPURCHASE.  As stated in the Prospectus, DWR and other selected
broker-dealers are authorized to repurchase shares represented by a share
certificate which is delivered to any of their offices. Shares held in a
shareholder's account without a share certificate may also be repurchased by DWR
and other selected broker-dealers upon the telephonic request of the
shareholder. The repurchase price is the net asset value next computed after
such purchase order is received by DWR or other selected broker-dealer reduced
by any applicable CDSC.
    
 
   
    PAYMENT FOR SHARES REDEEMED OR REPURCHASED.  As discussed in the Prospectus,
payment for shares of any Class presented for repurchase or redemption will be
made by check within seven days after receipt by the Transfer Agent of the
certificate and/or written request in good order. The term "good order" means
that the share certificate, if any, and request for redemption, are properly
signed, accompanied by any documentation required by the Transfer Agent, and
bear signature guarantees when required by the Fund or the Transfer Agent. Such
payment may be postponed or the right of redemption suspended at times (a) when
the New York Stock Exchange is closed for other than customary weekends and
holidays, (b) when trading on that Exchange is restricted, (c) when an emergency
exists as a result of which disposal by the Fund of securities owned by it is
not reasonably practicable or it is not reasonably practicable for the Fund
fairly to determine the value of its net assets, or (d) during any other period
when the Securities and Exchange Commission by order so permits; provided that
applicable rules and regulations of the Securities and Exchange Commission shall
govern as to whether the conditions prescribed in (b) or (c) exist. If the
shares to be redeemed have recently been purchased by check (including a
certified or bank cashier's check), payment of redemption proceeds may be
delayed for the minimum time needed to verify that the check used for investment
has been honored (not more than fifteen days from the time of receipt of the
check by the Transfer Agent). Shareholders maintaining margin accounts with DWR
or another selected broker-dealer are referred to their account executive
regarding restrictions on redemption of shares of the Fund pledged in the margin
account.
    
 
   
    TRANSFERS OF SHARES.  In the event a shareholder requests a transfer of any
shares to a new registration, such shares will be transferred without sales
charge at the time of transfer. With regard to the status of shares which are
either subject to a CDSC or free of such charge (and with regard to the length
of time shares subject to the charge have been held), any transfer involving
less than all of the shares in
    
 
                                       35
<PAGE>
   
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 redemption
or repurchase, reinstate any portion or all of the proceeds of such redemption
or repurchase in shares of the Fund in the same Class at the net asset value
next determined after a reinstatement request, together with the proceeds, is
received by the Transfer Agent.
    
 
    Exercise of the reinstatement privilege will not affect the federal income
tax and California personal income tax treatment of any gain or loss realized
upon the redemption or repurchase, except that if the redemption or repurchase
resulted in a loss and reinstatement is made in shares of the Fund, some or all
of the loss, depending on the amount reinstated, will not be allowed as a
deduction for federal income tax and California personal income tax purposes but
will be applied to adjust the cost basis of the shares acquired upon
reinstatement.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
    As stated in the Prospectus, the Fund intends to distribute all of its net
investment income and all of its net short-term capital gains, if any, and will
determine whether to retain all or part of any net long-term capital gains for
reinvestment.
 
    As discussed in the Prospectus, the Fund may invest a portion of its assets
in certain "private activity bonds" issued after August 7, 1986. As a result, a
portion of the exempt-interest dividends paid by the Fund may be an item of tax
preference to shareholders subject to the federal alternative minimum tax.
Certain corporations which are subject to the alternative minimum tax may also
have to include exempt-interest dividends in calculating their alternative
minimum taxable income in situations where the "adjusted current earnings" of
the corporation exceeds its alternative minimum taxable income.
 
    Each shareholder will be sent at least a quarterly summary of his or her
account, including information as to reinvested dividends and capital gains
distributions. Share certificates for dividends or distributions will not be
issued unless a shareholder requests in writing that a certificate be issued for
a specific number of shares.
 
    In computing interest income, the Fund will amortize any premiums and
original issue discounts on securities owned. Capital gains or losses realized
upon sale or maturity of such securities will be based on their amortized cost.
 
    Gains or losses on the sales of securities by the Fund will be long-term
capital gains or losses if the securities have been held by the Fund for more
than twelve months. Gains or losses on the sale of securities held for twelve
months or less will be short-term capital gains or losses. Gains and losses on
the sale, expiration or other termination of options on securities will
generally be treated as gains and losses from the sale of securities. Pursuant
to present federal income tax laws, futures contracts held by the Fund at the
end of each fiscal year will be required to be "marked to market", that is,
treated as having been sold at their fair market value at such date. Sixty
percent of any gain or loss recognized on these deemed sales will be treated as
long-term capital gain or loss, and the remainder will be treated as short-term
capital gain or loss. Gains or losses from options on futures and listed options
on debt instruments will similarly be treated as part short-term and part
long-term capital gains or losses, unless such gains or losses were incurred as
part of a securities "straddle," in which case the appropriate straddle rules of
the Internal Revenue Code (the "Code") would apply.
 
    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
 
                                       36
<PAGE>
tax. Shareholders will normally have to pay federal income taxes, and any
applicable state and/or local income taxes, on the dividends and distributions
they receive from the Fund. Such dividends and distributions, to the extent that
they are derived from net investment income or short-term capital gains, are
taxable to the shareholder as ordinary income regardless of whether the
shareholder receives such payments in additional shares or in cash. Any
dividends declared in the last quarter of any year which are paid in the
following calendar year prior to February 1 will be deemed received by the
shareholder in the prior calendar year.
 
    With respect to the Fund's investments in zero coupon bonds, the Fund
accrues income prior to any actual cash payments by their issuers. In order to
continue to comply with Subchapter M of the Code and remain able to forego
payment of Federal income tax on its income and capital gains, the Fund must
distribute all of its net investment income, including income accrued from zero
coupon bonds. As such, the Fund may be required to dispose of some of its
portfolio securities under disadvantageous circumstances to generate the cash
required for distribution.
 
    One of the requirements for regulated investment company status is that at
least 90% of a Fund's gross income be derived from dividends, interest, gains
from the sale or other disposition of securities and certain other related
income. Another requirement for regulated investment company status is that less
than 30% of the Fund's gross income can be derived from, among other sources,
gains from the sale or other disposition of securities held less than three
months. Accordingly, the Fund may be restricted in the writing of options on
securities held for less than three months, in the writing of options which
expire in less than three months, and in effecting closing transactions with
respect to call or put options which have been written or purchased less than
three months prior to such transactions. The Fund may also be restricted in its
ability to engage in transactions involving futures contracts.
 
    Under the Revenue Reconciliation Act of 1993, all or a portion of the Fund's
gain from the sale or redemption of tax-exempt obligations purchased at a market
discount after April 30, 1993 will be treated as ordinary income rather than
capital gain. This rule may increase the amount of ordinary income dividends
received by shareholders.
 
    As discussed in the Prospectus, the Fund intends to qualify to pay
"exempt-interest dividends" to its shareholders by maintaining, as of the close
of each quarter of its taxable year, at least 50% of the value of its total
assets in tax-exempt securities. An exempt-interest dividend is that part of
dividend distributions made by the Fund which consists of interest received by
the Fund on tax-exempt securities upon which the shareholder incurs no federal
income taxes.
 
    Within sixty days after the end of its fiscal year, the Fund will mail to
shareholders a statement indicating the percentage of the dividend distributions
for such fiscal year which constitutes exempt-interest dividends and the
percentage, if any, that is taxable, and the percentage, if any, of the exempt-
interest dividends which constitutes an item of tax preference, and to what
extent the taxable portion is long-term capital gain, short-term capital gain or
ordinary income. These percentages should be applied uniformly to all monthly
distributions made during the fiscal year to determine the proportion of
dividends that is tax-exempt. The percentages may differ from the percentage of
tax-exempt dividend distributions for any particular month.
 
    Shareholders will be subject to federal income tax on dividends paid from
interest income derived from taxable securities and on distributions of net
short-term capital gains. Such dividends and distributions are taxable to the
shareholder as ordinary dividend income regardless of whether the shareholder
receives such distributions in additional shares or in cash. Distributions of
long-term capital gains, if any, are taxable as long-term gains, regardless of
how long the shareholder has held Fund shares and whether the distribution is
received in additional shares or in cash. Since the Fund's income is expected to
be derived entirely from interest rather than dividends, none of such dividend
distributions will be eligible for the 70% dividends received deduction
generally available to corporations. Net long-term capital gains distributions
are not eligible for the dividends received deduction.
 
                                       37
<PAGE>
    Any loss on the sale or exchange of shares of the Fund which are held for
six months or less is disallowed to the extent of the amount of any
exempt-interest dividends paid with respect to such shares. Treasury Regulations
may provide for a reduction in such required holding period. If a shareholder
receives a distribution that is taxed as long-term capital gain on shares held
for six months or less and sells those shares at a loss, the loss will be
treated as a long-term capital loss to the extent of the capital gains
distribution.
 
    Interest on indebtedness incurred or continued by a shareholder to purchase
or carry shares of the Fund is not deductible to the extent allocable to
exempt-interest dividends of the Fund (which allocation does not take into
account capital gain dividends of the Fund). Furthermore, entities or persons
who are "substantial users" (or related persons) of facilities financed by
industrial development bonds should consult their tax advisers before purchasing
shares of the Fund. "Substantial user" is defined generally by Income Tax
Regulation 1.103-11 (b) as including a "non-exempt person" who regularly uses in
a trade or business a part of a facility financed from the proceeds of
industrial development bonds.
 
    From time to time, proposals have been introduced before Congress for the
purpose of restricting or eliminating the federal income tax exemption for
interest on municipal securities. It can be expected that similar proposals may
be introduced in the future. If such a proposal were enacted, the availability
of municipal securities for investment by the Fund could be affected. In such
event, the Fund would re-evaluate its investment objective and policies.
 
    In any year in which the Fund qualifies as a regulated investment company
under the Internal Revenue Code and is exempt from federal income tax, (i) the
Fund will also be exempt from the California corporate income and franchise
taxes to the extent it distributes its income and (ii), provided 50% or more of
the value of the total assets of the Fund at the close of each quarter of its
taxable year consists of obligations the interest on which (when held by an
individual) is exempt from personal income taxation under California law, the
Fund will be qualified under California law to pay "exempt-interest" dividends
which will be exempt from the California personal income tax.
 
    The portion of dividends constituting exempt-interest dividends is that
portion derived from interest on obligations which pay interest excludable from
California personal income under California law. The total amount of California
exempt-interest dividends paid by the Fund to all of its shareholders with
respect to any taxable year cannot exceed the amount of interest received by the
Fund during such year on such obligations less any expenses and expenditures
(including dividends paid to corporate shareholders) deemed to have been paid
from such interest. Any dividends paid to corporate shareholders subject to the
California franchise or corporate income tax will be taxed as ordinary dividends
to such shareholders.
 
    Individual shareholders of the Fund who reside in California will not be
subject to California personal income tax on distributions received from the
Fund to the extent such distributions are attributable to interest received by
the Fund during its taxable year on obligations, the interest from which (when
held by an individual) is exempt from taxation under California law.
 
    Because, unlike federal law, California law does not impose personal income
tax on an individual's Social Security benefits, the receipt of California
exempt-interest dividends will have no effect on an individual's California
personal income tax.
 
    Individual shareholders will normally be subject to federal and California
personal income tax on dividends paid from interest income derived from taxable
securities and distributions of net capital gains. In addition, distributions
other than exempt-interest dividends to such shareholders are includable in
income subject to the California alternative minimum tax. For federal and
California personal income tax purposes, distributions of long-term capital
gains, if any, are taxable to shareholders as long-term capital gains,
regardless of how long a shareholder has held shares of the Fund, and regardless
of whether the distributions are received in additional shares or in cash. In
addition, unlike federal law, California law provides that the shareholders of
the Fund will not be subject to tax, or receive a credit for tax paid by the
Fund, on undistributed capital gains, if any.
 
                                       38
<PAGE>
    Interest on indebtedness incurred by shareholders or related parties to
purchase or carry shares of an investment company paying exempt-interest
dividends, such as the Fund, generally will not be deductible by the investor
for California personal income tax purposes. In addition, as a result of
California's incorporation of certain provisions of the Code, a loss realized by
a shareholder upon the sale of shares held for six months or less may be
disallowed to the extent of any exempt-interest dividends received with respect
to such shares. Moreover, any loss realized upon the sale of shares within six
months from the date of purchase of such shares and following receipt of a
long-term capital gains distribution will be treated as a long-term capital loss
to the extent of such long-term capital gains distribution. Finally, any loss
realized upon the sale of shares within thirty days before or after the
acquisition of other shares of the Fund may be disallowed under the "wash sale"
rules.
 
    Distributions from investment income and long-term and short-term capital
gains will not be excluded from taxable income in determining the California
corporate franchise tax for corporate shareholders. Such distributions also may
be includable in income subject to the alternative minimum tax. In addition,
distributions from investment income and long-term and short-term capital gains
may be subject to state taxes in states other than California and to local
taxes.
 
    The foregoing is only a summary of some of the important California income
tax considerations generally affecting the Fund and its shareholders. No attempt
is made to present a detailed explanation of the California personal income tax
treatment of the Fund or its shareholders, and this discussion is not intended
as a substitute for careful planning. Shareholders should consult their tax
advisers regarding specific questions as to federal, state or local taxes and
how these relate to their own tax situation.
 
    The Fund is organized as a Massachusetts business trust. Under current law,
so long as it qualifies as a "regulated investment company" under the Internal
Revenue Code, the Fund itself is not liable for any income or franchise tax in
The Commonwealth of Massachusetts.
 
    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 fund by the exact amount of the dividend or
capital gains distribution. Furthermore, capital gains distributions are, and
some portion of the dividends may be, subject to income tax. If the net asset
value of the shares should be reduced below a shareholder's cost as a result of
the payment of taxable dividends or the distribution of realized long-term
capital gains, such payment or distribution would be in part a return of capital
but nonetheless taxable to the shareholder. Therefore, an investor should
consider the tax implications of purchasing Fund shares immediately prior to a
distribution record date.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
   
    As discussed in the Prospectus, from time to time the Fund may quote its
"yield" and/or its "total return" in advertisements and sales literature. These
figures are computed separately for Class A, Class B, Class C and Class D
shares. Yield is calculated for any 30-day period as follows: the amount of
interest income for each security in the Fund's portfolio is determined in
accordance with regulatory requirements; the total for the entire portfolio
constitutes the Fund's gross income for the period. Expenses accrued during the
period are subtracted to arrive at "net investment income" of each Class. The
resulting amount is divided by the product of the maximum offering price per
share on the last day of the period multiplied by the average number of shares
of the applicable Class outstanding during the period that were entitled to
dividends. This amount is added to 1 and raised to the sixth power. 1 is then
subtracted from the result and the difference is multiplied by 2 to arrive at
the annualized yield. For the 30-day period ended December 31, 1996, the Fund's
yield, calculated pursuant to the formula described above, was 4.07%. This yield
is for Class B only; there were no other Classes of shares outstanding on such
date.
    
 
   
    The Fund may also quote a "tax-equivalent yield" determined by dividing the
tax-exempt portion of the quoted yield by 1 minus the stated income tax rate and
adding the result to the portion of the yield
    
 
                                       39
<PAGE>
   
that is not tax-exempt. The Fund's tax-equivalent yield, based upon a combined
Federal and California personal income tax bracket of 46.24% (the highest
current individual marginal tax rate), for the 30-day period ending December 31,
1996, was 7.57% based upon the yield quoted above.
    
 
   
    The Fund's "average annual total return" represents an annualization of the
Fund's total return over a specified period and is computed by finding the
annual percentage rate which will result in the ending redeemable value of a
hypothetical $1,000 investment made at the beginning of a one, five or ten year
period, or for the period from the date of commencement of the Fund's
operations, if shorter than any of the foregoing. The ending redeemable value is
reduced by any CDSC at the end of the one, five or ten year or other period. For
the purpose of this calculation, it is assumed that all dividends and
distributions are reinvested. The formula for computing the average annual total
return involves a percentage obtained by dividing the ending redeemable value by
the amount of the initial investment, taking a root of the quotient (where the
root is equivalent to the number of years in the period) and subtracting 1 from
the result. The average annual total returns of the Fund for the one, five and
ten year periods ended December 31, 1996 were -1.74%, 5.61% and 6.30%,
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 return of the Fund may be calculated in the manner described in the
preceding paragraph, but without deduction for any applicable sales charge.
Based on this calculation, the average annual total returns of the Fund for the
one, five and ten year periods ended December 31, 1996 were 3.13%, 5.93% and
6.30%, 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 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 one, five and ten year periods ended December 31,
1996 were 3.13%, 33.40% and 84.15%, respectively. 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
$9,575, $48,250 and $97,250 in the case of Class A (investments of $10,000,
$50,000 and $100,000 adjusted for the initial sales charge) or by $10,000,
$50,000 and $100,000 in the case of each of Class B, 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 $27,792, $138,960 and $277,920, respectively, at
December 31, 1996. 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 a Special Meeting of Shareholders held on May 21, 1997. On that
date, Wayne E. Hedien was also elected as a Trustee of the Fund, with his term
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. 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 provides that no Trustee, officer, employee or
agent of the Fund is liable to the Fund or to a shareholder, nor is any Trustee,
officer, employee or agent liable to any third persons in connection with the
affairs of the Fund, except as such liability may arise from his/her or its own
bad faith, willful misfeasance, gross negligence, or reckless disregard of
his/her or its duties. It also provides that all third persons shall look solely
to the Fund property for satisfaction of claims arising in connection with the
affairs of the Fund. With the exceptions stated above, 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.

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

DEAN WITTER CALIFORNIA TAX-FREE INCOME FUND
NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1996
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter California Tax-Free Income Fund (the "Fund") is registered under the
Investment Company Act of 1940, as amended (the "Act"), as a diversified,
open-end management investment company. The Fund's investment objective is to
provide a high level of current income which is exempt from federal and
California income tax, consistent with the preservation of capital. The Fund was
organized as a Massachusetts business trust on April 9, 1984 and commenced
operations on July 11, 1984.
 
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 -- Portfolio securities are valued for the Fund by
an outside independent pricing service approved by the Trustees. The pricing
service has informed the Fund that in valuing the Fund's portfolio securities,
it uses both a computerized matrix of tax-exempt securities and evaluations by
its staff, in each case based on information concerning market transactions and
quotations from dealers which reflect the bid side of the market each day. The
Fund's portfolio securities are thus valued by reference to a combination of
transactions and quotations for the same or other securities believed to be
comparable in quality, coupon, maturity, type of issue, call provisions, trading
characteristics and other features deemed to be relevant. 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.
The Fund amortizes premiums and accretes discounts over the life of the
respective securities. Interest income is accrued daily.
 
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 and nontaxable income to its
shareholders. Accordingly, no federal income tax provision is required.

DEAN WITTER CALIFORNIA TAX-FREE INCOME FUND
NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1996, CONTINUED
 
D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends and
distributions to its shareholders on the record date. The amount of dividends
and distributions from net investment income and net realized capital gains are
determined in accordance with federal income tax regulations which may differ
from generally accepted accounting principles. These "book/tax" differences are
either considered temporary or permanent in nature. To the extent these
differences are permanent in nature, such amounts are reclassified within the
capital accounts based on their federal tax-basis treatment; temporary
differences do not require reclassification. Dividends and distributions which
exceed net investment income and net realized capital gains for financial
reporting purposes but not for tax purposes are reported as dividends in excess
of net investment income or distributions in excess of net realized capital
gains. To the extent they exceed net investment income and net realized capital
gains for tax purposes, they are reported as distributions of paid-in-capital.
 
2. INVESTMENT MANAGEMENT AGREEMENT
 
Pursuant to an Investment Management Agreement with Dean Witter InterCapital
Inc. (the "Investment Manager"), the Fund pays the Investment Manager a
management fee, accrued daily and payable monthly, by applying the following
annual rates to the Fund's net assets determined as of the close of each
business day: 0.55% to the portion of average daily net assets not exceeding
$500 million; 0.525% to the portion of average daily net assets exceeding $500
million but not exceeding $750 million; 0.50% to the portion of average daily
net assets exceeding $750 million but not exceeding $1 billion; and 0.475% to
the portion of average daily net assets exceeding $1 billion. Effective May 1,
1996, the annual rate was reduced to 0.45% to the portion of average daily net
assets in excess of $1.25 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 0.75% 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, account executives of Dean Witter Reynolds Inc., an affiliate of
the Investment Manager and Distributor, and other employees and selected
broker-dealers, 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 be compensated under the Plan for
its opportunity costs in advancing such amounts, which compensation would be in
the form of a carrying charge on any unreimbursed expenses by the Distributor.
 
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, totaled $3,649,503 at
December 31, 1996.
 
The Distributor has informed the Fund that for the year ended December 31, 1996,
it received approximately $1,325,000 in contingent deferred sales charges from
certain redemptions of the Fund's shares.
 
4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES
 
The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the year ended December 31, 1996 aggregated
$105,636,105 and $197,934,653, respectively.

Dean Witter Trust Company, an affiliate of the Investment Manager and
Distributor, is the Fund's transfer agent. At December 31, 1996, the Fund had
transfer agent fees and expenses payable of approximately $23,000.
 
The Fund has an unfunded noncontributory defined benefit pension plan covering
all independent Trustees of the Fund who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on years of service and compensation during the last five years
of service. Aggregate pension costs for the year ended December 31, 1996
included in Trustees' fees and expenses in the Statement of Operations amounted
to $933. At December 31, 1996, the Fund had an accrued pension liability of
$48,878 which is included in accrued expenses in the Statement of Assets and
Liabilities.

RATINGS OF INVESTMENTS
MOODY'S INVESTORS SERVICE INC. ("MOODY'S")
                             MUNICIPAL BOND RATINGS
 
Aaa   Bonds which are rated Aaa are judged to be of the best quality. They carry
      the smallest degree of investment risk and are generally referred to as
      "gilt edge." Interest payments are protected by a large or by an
      exceptionally stable margin and principal is secure. While the various
      protective elements are likely to change, such changes as can be
      visualized are most unlikely to impair the fundamentally strong position
      of such issues.
 
Aa    Bonds which are rated Aa are judged to be of high quality by all
      standards. Together with the Aaa group they comprise what are generally
      known as high grade bonds. They are rated lower than the best bonds
      because margins of protection may not be as large as in Aaa securities or
      fluctuation of protective elements may be of greater amplitude or there
      may be other elements present which make the long-term risks appear
      somewhat larger than in Aaa securities.
 
A     Bonds which are rated A possess many favorable investment attributes and
      are to be considered as upper medium grade obligations. Factors giving
      security to principal and interest are considered adequate, but elements
      may be present which suggest a susceptibility to impairment sometime in
      the future.
 
Baa   Bonds which are rated Baa are considered as medium grade obligations;
      i.e., they are neither highly protected nor poorly secured. Interest
      payments and principal security appear adequate for the present but
      certain protective elements may be lacking or may be characteristically
      unreliable over any great length of time. Such bonds lack outstanding
      investment characteristics and in fact have speculative characteristics as
      well.
 
      Bonds rated Aaa, Aa, A and Baa are considered investment grade bonds.
 
Ba    Bonds which are rated Ba are judged to have speculative elements; their
      future cannot be considered as well assured. Often the protection of
      interest and principal payments may be very moderate, and therefore not
      well safeguarded during both good and bad times over the future.
      Uncertainty of position characterizes bonds in this class.
 
B     Bonds which are rated B generally lack characteristics of the desirable
      investment. Assurance of interest and principal payments or of maintenance
      of other terms of the contract over any long period of time may be small.
 
Caa   Bonds which are rated Caa are of poor standing. Such issues may be in
      default or there may be present elements of danger with respect to
      principal or interest.
 
Ca    Bonds which are rated Ca present obligations which are speculative in a
      high degree. Such issues are often in default or have other marked
      shortcomings.
 
C     Bonds which are rated C are the lowest rated class of bonds, and issues so
      rated can be regarded as having extremely poor prospects of ever attaining
      any real investment standing.
 
    CONDITIONAL RATING:  Bonds for which the security depends upon the
completion of some act or the fulfillment of some condition are rated
conditionally. These are bonds secured by (a) earnings of projects under
construction, (b) earnings of projects unseasoned in operation experience, (c)
rentals which begin when facilities are completed, or (d) payments to which some
other limiting condition attaches. Parenthetical rating denotes probable credit
stature upon completion of construction or elimination of basis of condition.
 
    RATING REFINEMENTS:  Moody's may apply numerical modifiers, 1, 2 and 3 in
each generic rating classification from Aa through B in its municipal bond
rating system. The modifier 1 indicates a mid-range ranking; and a modifier 3
indicates that the issue ranks in the lower end of its generic rating category.

<PAGE>
                             MUNICIPAL NOTE RATINGS
 
    Moody's ratings for state and municipal notes and other short-term loans are
designated Moody's Investment Grade (MIG). MIG 1 denotes best quality and means
there is present strong protection from established cash flows, superior
liquidity support or demonstrated broad-based access to the market for
refinancing. MIG 2 denotes high quality and means that margins of protection are
ample although not as large as in MIG 1. MIG 3 denotes favorable quality and
means that all security elements are accounted for but that the undeniable
strength of the previous grades, MIG 1 and MIG 2, is lacking. MIG 4 denotes
adequate quality and means that the protection commonly regarded as required of
an investment security is present and that while the notes are not distinctly or
predominantly speculative, there is specific risk.
 
                        VARIABLE RATE DEMAND OBLIGATIONS
 
    A short-term rating, in addition to the Bond or MIG ratings, designated VMIG
may also be assigned to an issue having a demand feature. The assignment of the
VMIG symbol reflects such characteristics as payment upon periodic demand rather
than fixed maturity dates and payment relying on external liquidity. The VMIG
rating criteria are identical to the MIG criteria discussed above.
 
                            COMMERCIAL PAPER RATINGS
 
    Moody's Commercial Paper ratings are opinions of the ability to repay
punctually promissory obligations not having an original maturity in excess of
nine months. These ratings apply to Municipal Commercial Paper as well as
taxable Commercial Paper. Moody's employs the following three designations, all
judged to be investment grade, to indicate the relative repayment capacity of
rated issuers: Prime-1, Prime-2, Prime-3.
 
    Issuers rated Prime-1 have a superior capacity for repayment of short-term
promissory obligations. Issuers rated Prime-2 have a strong capacity for
repayment of short-term promissory obligations; and Issuers rated Prime-3 have
an acceptable capacity for repayment of short-term promissory obligations.
lssuers rated Not Prime do not fall within any of the Prime rating categories.
 
STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S")
 
                             MUNICIPAL BOND RATINGS
 
    A Standard & Poor's municipal bond rating is a current assessment of the
creditworthiness of an obligor with respect to a specific obligation. This
assessment may take into consideration obligors such as guarantors, insurers, or
lessees.
 
    The ratings are based on current information furnished by the issuer or
obtained by Standard & Poor's from other sources it considers reliable. The
ratings are based, in varying degrees, on the following considerations: (1)
likelihood of default-capacity and willingness of the obligor as to the timely
payment of interest and repayment of principal in accordance with the terms of
the obligation; (2) nature of and provisions of the obligation; and (3)
protection afforded by, and relative position of, the obligation in the event of
bankruptcy, reorganization or other arrangement under the laws of bankruptcy and
other laws affecting creditors' rights.
 
    Standard & Poor's does not perform an audit in connection with any rating
and may, on occasion, rely on unaudited financial information. The ratings may
be changed, suspended or withdrawn as a result of changes in, or unavailability
of, such information, or for other reasons.
 
AAA   Debt rated "AAA" has the highest rating assigned by Standard & Poor's.
      Capacity to pay interest and repay principal is extremely strong.
 
AA    Debt rated "AA" has a very strong capacity to pay interest and repay
      principal and differs from the highest-rated issues only in small degree.
 
                                       59
<PAGE>
A     Debt rated "A" has a strong capacity to pay interest and repay principal
      although they are somewhat more susceptible to the adverse effects of
      changes in circumstances and economic conditions than debt in higher-rated
      categories.
 
BBB   Debt rated "BBB" is regarded as having an adequate capacity to pay
      interest and repay principal. Whereas it normally exhibits adequate
      protection parameters, adverse economic conditions or changing
      circumstances are more likely to lead to a weakened capacity to pay
      interest and repay principal for debt in this category than for debt in
      higher-rated categories.
 
      Bonds rated AAA, AA, A and BBB are considered investment grade bonds.
 
BB    Debt rated "BB" has less near-term vulnerability to default than other
      speculative grade debt. However, it faces major ongoing uncertainties or
      exposure to adverse business, financial or economic conditions which could
      lead to inadequate capacity to meet timely interest and principal payment.
 
B     Debt rated "B" has a greater vulnerability to default but presently has
      the capacity to meet interest payments and principal repayments. Adverse
      business, financial or economic conditions would likely impair capacity or
      willingness to pay interest and repay principal.
 
CCC   Debt rated "CCC" has a current identifiable vulnerability to default, and
      is dependent upon favorable business, financial and economic conditions to
      meet timely payments of interest and repayments of principal. In the event
      of adverse business, financial or economic conditions, it is not likely to
      have the capacity to pay interest and repay principal.
 
CC    The rating "CC" is typically applied to debt subordinated to senior debt
      which is assigned an actual or implied "CCC" rating.
 
C     The rating "C" is typically applied to debt subordinated to senior debt
      which is assigned an actual or implied "CCC" debt rating.
 
CI    The rating "CI" is reserved for income bonds on which no interest is being
      paid.
 
D     Debt rated "D" is in payment default. The 'D' rating category is used when
      interest payments or principal payments are not made on the date due even
      if the applicable grace period has not expired, unless S&P believes that
      such payments will be made during such grace period. The "D" rating also
      will be used upon the filing of a bankruptcy petition if debt service
      payments are jeopardized.
 
NR    Indicates that no rating has been requested, that there is insufficient
      information on which to base a rating or that Standard & Poor's does not
      rate a particular type of obligation as a matter of policy.
 
      Bonds rated "BB", "B", "CCC", "CC" and "C" are regarded as having
      predominantly speculative characteristics with respect to capacity to pay
      interest and repay principal. "BB" indicates the least degree of
      speculation and "C" the highest degree of speculation. While such debt
      will likely have some quality and protective characteristics, these are
      outweighed by large uncertainties or major risk exposures to adverse
      conditions.
 
      PLUS (+) OR MINUS (-): The ratings from "AA" to "CCC" may be modified by
      the addition of a plus or minus sign to show relative standing within the
      major ratings categories.
 
      The foregoing ratings are sometimes followed by a "p" which indicates that
      the rating is provisional. A provisional rating assumes the successful
      completion of the project being financed by the bonds being rated and
      indicates that payment of debt service requirements is largely or entirely
      dependent upon the successful and timely completion of the project. This
      rating, however, while addressing credit quality subsequent to completion
      of the project, makes no comment on the likelihood or risk of default upon
      failure of such completion.

                             MUNICIPAL NOTE RATINGS
 
    Commencing on July 27, 1984, Standard & Poor's instituted a new rating
category with respect to certain municipal note issues with a maturity of less
than three years. The new note ratings denote the following:
 
    SP-1  denotes a very strong or strong capacity to pay principal and
          interest. Issues determined to possess overwhelming safety
          characteristics are given a plus (+) designation (SP-1+).
 
    SP-2  denotes a satisfactory capacity to pay principal and interest.
 
    SP-3  denotes a speculative capacity to pay principal and interest.
 
                            COMMERCIAL PAPER RATINGS
 
    Standard and Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days. The commercial paper rating is not a recommendation to purchase or
sell a security. The ratings are based upon current information furnished by the
issuer or obtained by S&P from other sources it considers reliable. The ratings
may be changed, suspended, or withdrawn as a result of changes in or
unavailability of such information. Ratings are graded into group categories,
ranging from "A" for the highest quality obligations to "D" for the lowest.
Ratings are applicable to both taxable and tax-exempt commercial paper. The
categories are as follows:
 
    Issues assigned A ratings are regarded as having the greatest capacity for
timely payment. Issues in this category are further refined with the designation
1, 2 and 3 to indicate the relative degree of safety.
 
A-1 indicates that the degree of safety regarding timely payment is very strong.
 
A-2 indicates capacity for timely payment on issues with this designation is
strong. However, the relative degree of safety is not as overwhelming as for
issues designated "A-1".
 
A-3 indicates a satisfactory capacity for timely payment. Obligations carrying
this designation are, however, somewhat more vulnerable to the adverse effects
of changes in circumstances than obligations carrying the higher designations.

Item 27. INDEMNIFICATION

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

<PAGE>


         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.

                     INSTRUMENT ESTABLISHING AND DESIGNATING
                          ADDITIONAL CLASSES OF SHARES

WHEREAS, Dean Witter California Tax-Free Income Fund (the "Trust") was
established by the Declaration of Trust dated April 9, 1984, as amended from
time to time (the "Declaration"), under the laws of the Commonwealth of
Massachusetts;

WHEREAS, Section 6.9(g) of the Declaration provides that the establishment and
designation of any additional class of shares shall be effective upon the
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
instrument shall have the status of an amendment to the Declaration; and

WHEREAS, the Trustees of the Trust have deemed it advisable to establish and

NOW, THEREFORE, BE IT RESOLVED, pursuant to Section 6.9(g) of the Declaration,
there are hereby established and designated three additional classes of shares,

and the Additional Classes; and be it further

RESOLVED, pursuant to Section 6.9(g) of the Declaration, all shares of the Trust
held prior to July 28, 1997 are hereby designated as Class B shares of the
Trust.

This instrument may be executed in more than one counterpart, each of which
shall be deemed an original, but all of which together shall constitute one and

                               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.

    AGREEMENT made as of the 31st day of May, 1997 by and between Dean Witter
California Tax-Free Income Fund, an unincorporated business trust organized
under the laws of the Commonwealth of Massachusetts (hereinafter called the
"Fund"), and Dean Witter InterCapital Inc., a Delaware corporation (hereinafter
called the "Investment Manager"):
 
    WHEREAS, The Fund is engaged in business as an open-end management
investment company and is registered as such under the Investment Company Act of
1940, as amended (the "Act"); and
 
    WHEREAS, The Investment Manager is registered as an investment adviser under
the Investment Advisers Act of 1940, and engages in the business of acting as
investment adviser; and
 
    WHEREAS, The Fund desires to retain the Investment Manager to render
management and investment advisory services in the manner and on the terms and
conditions hereinafter set forth; and
 
    WHEREAS, The Investment Manager desires to be retained to perform services
on said terms and conditions:
 
    Now, Therefore, this Agreement
 
                              W I T N E S S E T H:
 
that in consideration of the premises and the mutual covenants hereinafter
contained, the Fund and the Investment Manager agree as follows:
 
     1. The Fund hereby retains the Investment Manager to act as investment
manager of the Fund and, subject to the supervision of the Trustees, to
supervise the investment activities of the Fund as hereinafter set forth.
Without limiting the generality of the foregoing, the Investment Manager shall
obtain and evaluate such information and advice relating to the economy,
securities and commodities markets and securities and commodities as it deems
necessary or useful to discharge its duties hereunder; shall continuously manage
the assets of the Fund in a manner consistent with the investment objectives and
policies of the Fund; shall determine the securities and commodities to be
purchased, sold or otherwise disposed of by the Fund and the timing of such
purchases, sales and dispositions; and shall take such further action, including
the placing of purchase and sale orders on behalf of the Fund, as the Investment
Manager shall deem necessary or appropriate. The Investment Manager shall also
furnish to or place at the disposal of the Fund such of the information,
evaluations, analyses and opinions formulated or obtained by the Investment
Manager in the discharge of its duties as the Fund may, from time to time,
reasonably request.
 
     2. The Investment Manager shall, at its own expense, maintain such staff
and employ or retain such personnel and consult with such other persons as it
shall from time to time determine to be necessary or useful to the performance
of its obligations under this Agreement. Without limiting the generality of the
foregoing, the staff and personnel of the Investment Manager shall be deemed to
include persons employed or otherwise retained by the Investment Manager to
furnish statistical and other factual data, advice regarding economic factors
and trends, information with respect to technical and scientific developments,
and such other information, advice and assistance as the Investment Manager may
desire. The Investment Manager shall, as agent for the Fund, maintain the Fund's
records and books of account (other than those maintained by the Fund's transfer
agent, registrar, custodian and other agencies). All such books and records so
maintained shall be the property of the Fund and, upon request therefor, the
Investment Manager shall surrender to the Fund such of the books and records so
requested.
 
     3. The Fund will, from time to time, furnish or otherwise make available to
the Investment Manager such financial reports, proxy statements and other
information relating to the business and affairs of the Fund as the Investment
Manager may reasonably require in order to discharge its duties and obligations
hereunder.
 
     4. The Investment Manager shall bear the cost of rendering the investment
management and supervisory services to be performed by it under this Agreement,
and shall, at its own expense, pay the compensation of the officers and
employees, if any, of the Fund, and provide such office space, facilities and
equipment
<PAGE>
and such clerical help and bookkeeping services as the Fund shall reasonably
require in the conduct of its business. The Investment Manager shall also bear
the cost of telephone service, heat, light, power and other utilities provided
to the Fund.
 
     5. The Fund assumes and shall pay or cause to be paid all other expenses of
the Fund, including without limitation: fees pursuant to any plan of
distribution that the Fund may adopt; the charges and expenses of any registrar,
any custodian or depository appointed by the Fund for the safekeeping of its
cash, portfolio securities or commodities and other property, and any stock
transfer or dividend agent or agents appointed by the Fund; brokers' commissions
chargeable to the Fund in connection with portfolio transactions to which the
Fund is a party; all taxes, including securities or commodities issuance and
transfer taxes, and fees payable by the Fund to federal, state or other
governmental agencies; the cost and expense of engraving or printing
certificates representing shares of the Fund; all costs and expenses in
connection with the registration and maintenance of registration of the Fund and
its shares with the Securities and Exchange Commission and various states and
other jurisdictions (including filing fees and legal fees and disbursements of
counsel); the cost and expense of printing, including typesetting, and
distributing prospectuses and statements of additional information of the Fund
and supplements thereto to the Fund's shareholders; all expenses of
shareholders' and Trustees' meetings and of preparing, printing and mailing
proxy statements and reports to shareholders; fees and travel expenses of
Trustees or members of any advisory board or committee who are not employees of
the Investment Manager or any corporate affiliate of the Investment Manager; all
expenses incident to the payment of any dividend, distribution, withdrawal or
redemption, whether in shares or in cash; charges and expenses of any outside
service used for pricing of the Fund's shares; charges and expenses of legal
counsel, including counsel to the Trustees of the Fund who are not interested
persons (as defined in the Act) of the Fund or the Investment Manager, and of
independent accountants, in connection with any matter relating to the Fund;
membership dues of industry associations; interest payable on Fund borrowings;
postage; insurance premiums on property or personnel (including officers and
Trustees) of the Fund which inure to its benefit; extraordinary expenses
(including but not limited to legal claims and liabilities and litigation costs
and any indemnification related thereto); and all other charges and costs of the
Fund's operation unless otherwise explicitly provided herein.
 
     6. For the services to be rendered, the facilities furnished, and the
expenses assumed by the Investment Manager, the Fund shall pay to the Investment
Manager monthly compensation determined by applying the following annual rates
to the Fund's daily net assets: 0.55% of daily net assets up to $500 million;
0.525% of the next $250 million; 0.50% of the next $250 million; 0.475% of the
next $250 million; and 0.45% of daily net assets over $1.25 billion. Except as
hereinafter set forth, compensation under this Agreement shall be calculated and
accrued daily and the amounts of the daily accruals shall be paid monthly. Such
calculations shall be made by applying 1/365ths of the annual rates to the
Fund's net assets each day determined as of the close of business on that day or
the last previous business day. If this Agreement becomes effective subsequent
to the first day of a month or shall terminate before the last day of a month,
compensation for that part of the month this Agreement is in effect shall be
prorated in a manner consistent with the calculation of the fees as set forth
above.
 
    Subject to the provisions of paragraph 7 hereof, payment of the Investment
Manager's compensation for the preceding month shall be made as promptly as
possible after completion of the computations contemplated by paragraph 7
hereof.
 
     7. In the event the operating expenses of the Fund, including amounts
payable to the Investment Manager pursuant to paragraph 6 hereof, for any fiscal
year ending on a date on which this Agreement is in effect, exceed the expense
limitations applicable to the Fund imposed by state securities laws or
regulations thereunder, as such limitations may be raised or lowered from time
to time, the Investment Manager shall reduce its management fee to the extent of
such excess and, if required, pursuant to any such laws or regulations, will
reimburse the Fund for annual operating expenses in excess of any expense
limitation that may be applicable; provided, however, there shall be excluded
from such expenses the amount of any interest, taxes, brokerage commissions,
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 the Fund. Such reduction, if any, shall be computed
and accrued daily, shall be settled on a monthly basis, and shall be based upon
the expense limitation applicable to the Fund as at the end of the last
 
                                       2
<PAGE>
business day of the month. Should two or more such expense limitations be
applicable as at the end of the last business day of the month, that expense
limitation which results in the largest reduction in the Investment Manager's
fee shall be applicable.
 
    For purposes of this provision, should any applicable expense limitation be
based upon the gross income of the Fund, such gross income shall include, but
not be limited to, interest on debt securities in the Fund's portfolio accrued
to and including the last day of the Fund's fiscal year, and dividends declared
on equity securities in the Fund's portfolio, the record dates for which fall on
or prior to the last day of such fiscal year, but shall not include gains from
the sale of securities.
 
     8. The Investment Manager will use its best efforts in the supervision and
management of the investment activities of the Fund, but in the absence of
willful misfeasance, bad faith, gross negligence or reckless disregard of its
obligations hereunder, the Investment Manager shall not be liable to the Fund or
any of its investors for any error of judgment or mistake of law or for any act
or omission by the Investment Manager or for any losses sustained by the Fund or
its investors.
 
     9. Nothing contained in this Agreement shall prevent the Investment Manager
or any affiliated person of the Investment Manager from acting as investment
adviser or manager for any other person, firm or corporation and shall not in
any way bind or restrict the Investment Manager or any such affiliated person
from buying, selling or trading any securities or commodities for their own
accounts or for the account of others for whom they may be acting. Nothing in
this Agreement shall limit or restrict the right of any Trustee, officer or
employee of the Investment Manager to engage in any other business or to devote
his or her time and attention in part to the management or other aspects of any
other business whether of a similar or dissimilar nature.
 
    10. This Agreement shall remain in effect until April 30, 1999 and from year
to year thereafter provided such continuance is approved at least annually by
the vote of holders of a majority, as defined in the Investment Company Act of
1940, as amended (the "Act"), of the outstanding voting securities of the Fund
or by the Trustees of the Fund; provided that in either event such continuance
is also approved annually by the vote of a majority of the Trustees of the Fund
who are not parties to this Agreement or "interested persons" (as defined in the
Act) of any such party, which vote must be cast in person at a meeting called
for the purpose of voting on such approval; provided, however, that (a) the Fund
may, at any time and without the payment of any penalty, terminate this
Agreement upon thirty days' written notice to the Investment Manager, either by
majority vote of the Trustees of the Fund or by the vote of a majority of the
outstanding voting securities of the Fund; (b) this Agreement shall immediately
terminate in the event of its assignment (to the extent required by the Act and
the rules thereunder) unless such automatic terminations shall be prevented by
an exemptive order of the Securities and Exchange Commission; and (c) the
Investment Manager may terminate this Agreement without payment of penalty on
thirty days' written notice to the Fund. Any notice under this Agreement shall
be given in writing, addressed and delivered, or mailed post-paid, to the other
party at the principal office of such party.
 
    11. This Agreement may be amended by the parties without the vote or consent
of the shareholders of the Fund to supply any omission, to cure, correct or
supplement any ambiguous, defective or inconsistent provision hereof, or if they
deem it necessary to conform this Agreement to the requirements of applicable
federal laws or regulations, but neither the Fund nor the Investment Manager
shall be liable for failing to do so.
 
    12. This Agreement shall be construed in accordance with the laws of the
State of New York and the applicable provisions of the Act. To the extent the
applicable law of the State of New York, or any of the provisions herein,
conflicts with the applicable provisions of the Act, the latter shall control.
 
    13. The Investment Manager and the Fund each agree that the name "Dean
Witter," which comprises a component of the Fund's name, is a property right of
Dean Witter Reynolds Inc. The Fund agrees and consents that (i) it will only use
the name "Dean Witter" as a component of its name and for no other purpose, (ii)
it will not purport to grant to any third party the right to use the name "Dean
Witter" for 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
 
                                       3
<PAGE>
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 California Tax-Free
Income Fund, dated April 9, 1984, 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 California
Tax-Free Income Fund refers to the Trustees under the Declaration collectively
as Trustees, but not as individuals or personally; and no Trustee, shareholder,
officer, employee or agent of Dean Witter California Tax-Free Income Fund shall
be held to any personal liability, nor shall resort be had to their private
property for the satisfaction of any obligation or claim or otherwise, in
connection with the affairs of said Dean Witter California Tax-Free Income Fund,
but the Trust Estate only shall be liable.
 
    IN WITNESS WHEREOF, the parties hereto have executed and delivered this
Agreement on the day and year first above written in New York, New York.

                             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.

                               DEAN WITTER FUNDS

                             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 CALIFORNIA TAX-FREE INCOME FUND

   WHEREAS, Dean Witter California Tax-Free Income Fund (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 October 26, 1995, 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 June 26, 1984, 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 June 26, 1984, 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 0.75%, 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

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) 0.75% 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) 0.75% per annum of
the average daily net assets of Class B. Such compensation shall be
calculated and accrued daily and paid monthly or at such other intervals as
the 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, provided that, with respect to Class B, carryover expenses as
a percentage of Fund assets will not be materially increased thereby. It is

                                2
<PAGE>

contemplated that, with respect to Class A shares, the entire fee set forth
in paragraph 1(a) will be characterized as a service fee within the meaning
of the National Association of Securities Dealers, Inc. guidelines and that,
with respect to Class B shares, payments at the annual rate of 0.20% will be
so characterized and that, with respect to Class C shares, payments at the
annual rate of 0.25% will be so characterized.

   3. This Plan, 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 California Tax-Free
Income Fund, dated April 9, 1984, 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 California Tax-Free Income Fund refers to the Trustees under the
Declaration collectively as Trustees but not as individuals or personally;
and no Trustee, shareholder, officer, employee or agent of Dean Witter
California Tax-Free Income Fund 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 California Tax-Free Income Fund, but the Trust Estate only shall be
liable.

                              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.
