THE FUND
 
ICON                INVESTMENT OBJECTIVE
- --------------------------------------------------------------------------------
                    Morgan Stanley Dean Witter California Tax-Free Income Fund
                    is a mutual fund that seeks to provide a high level of
                    current income exempt from federal and California income
                    tax, consistent with the preservation of capital. There is
                    no guarantee that the Fund will achieve this objective.
 
ICON                PRINCIPAL INVESTMENT STRATEGIES
- --------------------------------------------------------------------------------
                    The Fund will normally invest at least 80% of its assets in
                    securities that pay interest exempt from federal and
                    California state income taxes. The Fund's "Investment
                    Manager," Morgan Stanley Dean Witter Advisors Inc.,
                    generally invests the Fund's assets in investment grade,
                    California municipal obligations. Municipal obligations are
                    bonds, notes or short-term commercial paper issued by state
                    and local governments, or their respective agencies. The
                    municipal obligations may be rated investment grade by
                    Moody's Investors Service Inc. or Standard & Poor's
                    Corporation Fitch Investors Service L.P. or, if unrated,
                    judged to be of comparable quality by the Investment Manager
                    at the time of purchase.
 
                    The Fund may invest up to 20% of its assets in taxable money
                    market instruments, tax-exempt securities of other states
                    and municipalities, futures, and securities that pay
                    interest income subject to the "alternative minimum tax",
                    and some taxpayers may have to pay tax on a Fund
                    distribution of this income. The Fund, therefore, may not be
                    a suitable investment for these investors. See the "Tax
                    Consequences" section for more details.
 
                    Municipal obligations typically are "general obligation" or
                    "revenue" bonds, notes or commercial paper. The general
                    obligation securities are secured by the issuer's faith and
                    credit, as well as its taxing power, for payment of
                    principal and interest. Revenue bonds, however, are
                    generally payable from a specific revenue source. They are
                    issued for a wide variety of projects such as financing
                    public utilities, housing units, airports, highways, and
                    schools. Included in the revenue bonds category are
                    participations in lease obligations. The Fund's municipal
                    obligation investments may include zero coupon securities,
                    which are purchased at a discount and make no interest
                    payments until maturity.
 
                    In pursuing the Fund's investment objective, the Investment
                    Manager has considerable leeway in deciding which
                    investments it buys, holds or sells on a day-to-day basis --
                    and which investment strategies it uses. For example, the
                    Investment Manager in its discretion may determine to use
                    some permitted investment strategies while not using others.
 
ICON                PRINCIPAL RISKS
- --------------------------------------------------------------------------------
                    The Fund's share price will fluctuate with changes in the
                    market value of the Fund's portfolio securities. When you
                    sell Fund shares, they may be worth less than what you paid
                    for them and, accordingly, you can lose money investing in
                    this Fund.
 
                    CREDIT AND INTEREST RATE RISKS. Principal risks of investing
                    in the Fund are associated with its municipal investments,
                    particularly its concentration in municipal obligations of a
                    single state. Municipal obligations, as with other debt
                    securities, are
 
                                                                               1
<PAGE>
                    subject to two types of risks: credit risk and interest rate
                    risk. Credit risk refers to the possibility that the issuer
                    of a security will be unable or unwilling to make interest
                    payments and/or repay the principal on its debt. In the case
                    of revenue bonds, notes or commercial paper, for example,
                    the credit risk is the possibility that the user fees from a
                    project or other specified revenue sources are insufficient
                    to meet interest and/or principal payment obligations. The
                    issuers of private activity bonds, used to finance such
                    projects as health care facilities and water treatment
                    facilities, also may be negatively impacted by the general
                    credit of the user of the project.
 
                    Interest rate risk refers to fluctuations in the value of a
                    fixed-income security resulting from changes in the general
                    level of interest rates. When the general level of interest
                    rates goes up, the prices of most fixed-income securities go
                    down. When the general level of interest rates goes down,
                    the prices of most fixed-income securities go up. (Zero
                    coupon securities are typically subject to greater price
                    fluctuations than comparable securities that pay interest.)
                    As merely illustrative of the relationship between
                    fixed-income securities and interest rates, the following
                    table shows how interest rates affect bond prices.

</TABLE>
 
                    Coupons reflect yields on AAA-rated municipals as of
                    December 31, 1998. In addition, the table is an illustration
                    and does not represent expected yields or share price
                    changes of any Morgan Stanley Dean Witter mutual fund.
 
                    The Fund is not limited as to the maturities of the
                    municipal securities in which it may invest. Thus, a rise in
                    the general level of interest rates may cause the price of
                    the Fund's portfolio securities to fall substantially. In
                    addition, while the Fund invests in investment grade
                    fixed-income securities, these securities may have
                    speculative characteristics.
 
                    OTHER RISKS. The performance of the Fund also will depend on
                    whether the Investment Manager is successful in pursuing the
                    Fund's investment strategy. The Fund is also subject to
                    other risks from its permissible investments including the
                    risks associated with its futures and lease obligations
                    investments.
 
                    Shares of the Fund are not bank deposits and are not
                    guaranteed or insured by any bank, governmental entity, or
                    the FDIC.

                    The bar chart reflects the performance of Class B shares;
                    the performance of the other Classes will differ because the
                    Classes have different ongoing fees. The performance
                    information in the bar chart does not reflect the deduction
                    of sales charges; if these amounts were reflected, returns
                    would be less than shown.
 
                    During the periods shown in the bar chart, the highest
                    return for a calendar quarter was 6.11% (quarter ended March
                    31, 1995) and the lowest return for a calendar quarter was
                    -5.10% (quarter ended March 31, 1994). Year-to-date total
                    return as of March 31, 1999 was    %.

     purchase are subject to a contingent deferred sales charge ("CDSC") of
     1.00% that will be imposed on sales made within one year after purchase,
     except for certain specific circumstances.
(3)  The CDSC is scaled down to 1.00% during the sixth year, reaching zero

                    EXAMPLE
                    This example is intended to help you compare the cost of
                    investing in the Fund with the cost of investing in other
                    mutual funds.
 
                    The example assumes that you invest $10,000 in the Fund,
                    your investment has a 5% return each year, and the Fund's
                    operating expenses remain the same. Although your actual
                    costs may be higher or lower, the tables below show your
                    costs at the end of each period based on these assumptions
                    depending upon whether or not you sell your shares at the
                    end of each period.

ICON                ADDITIONAL INVESTMENT STRATEGY INFORMATION
- --------------------------------------------------------------------------------
                    This section provides additional information concerning the
                    Fund's principal investments.
 
                    The Fund's policy of investing at least eighty percent of
                    its assets in securities the interest on which is exempt
                    from federal income taxes and California state income taxes,
                    except for "defensive" investing discussed below, is
                    fundamental. This fundamental policy may not be changed
                    without shareholder approval. In addition, the Fund will
                    only purchase California tax-exempt securities that satisfy
                    the following standards: (a) California municipal bonds that
                    are rated investment grade by Moody's Investors Service or
                    Standard & Poor's, (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 an
                    outstanding issue of California investment grade municipal
                    bonds, (c) California municipal commercial paper rated in
                    the highest category by Moody's or S&P, (d) and unrated
                    securities judged by the Investment Manager to be of
                    comparable quality at the time of purchase.
 
                    BOND INSURANCE RISK. Many of the municipal obligations the
                    Fund invests in will be covered by insurance at the time of
                    issuance or at a later date. Such insurance covers the
                    remaining term of the security. Insured municipal
                    obligations would generally be assigned a lower rating if
                    the rating were based primarily on the credit quality of the
                    issuer without regard to the insurance feature. If the
                    claims-paying ability of the insurer were downgraded, the
                    ratings on the municipal obligations it insures may also be
                    downgraded.
 
                    LEASE OBLIGATIONS. Included within the revenue bonds
                    category are participations in lease obligations or
                    installment purchase contracts of municipalities. Generally,
                    state and local agencies or authorities issue lease
                    obligations to acquire equipment and facilities.
 
                    FUTURES. The Fund may purchase or sell futures contracts
                    with respect to financial instruments and municipal bond
                    indexes. Futures may be used to seek to hedge against
                    interest rate changes.
 
                    DEFENSIVE INVESTING. The Fund may take temporary "defensive"
                    positions in attempting to respond to adverse market
                    conditions. The Fund may invest any amount of its assets in
                    taxable money market securities and non-California tax-
                    exempt securities when the Investment Manager believes it is
                    advisable to do so. The Fund will only purchase municipal
                    obligations of other states that satisfy the same standards
                    as set forth for the California tax-exempt securities.
                    Although taking a defensive posture is designed to protect
                    the Fund from an anticipated market downturn, it could have
                    the effect of reducing the Fund's ability to provide tax-
                    exempt income.
 
ICON                ADDITIONAL RISK INFORMATION
- --------------------------------------------------------------------------------
                    As discussed in the "Principal Risks" section, principal
                    risks of investing in the Fund are associated with its
                    fixed-income securities investments. This section provides
                    additional information regarding the principal risks of
                    investing in the Fund.
 
                                                                               5
<PAGE>
                    LEASE OBLIGATIONS. 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 that 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 these legislative actions do
                    not occur, the holders of the lease obligation may
                    experience difficulty in exercising their rights, including
                    disposition of the property.
 
                    FUTURES. If the Fund purchases and sells futures contracts,
                    its participation in these markets would subject the Fund's
                    portfolio to certain risks. The Investment Manager's
                    predictions of movements in the direction of interest rate
                    markets may be inaccurate, and the adverse consequences to
                    the Fund (e.g., a reduction in the Fund's net asset value or
                    a reduction in the amount of income available for
                    distribution) may leave the Fund in a worse position than if
                    these strategies were not used. Other risks inherent in the
                    use of futures include, for example, the possible imperfect
                    correlation between the price of futures contracts and
                    movements in the prices of the securities being hedged, and
                    the possible absence of a liquid secondary market for any
                    particular instrument. The risk of imperfect correlations
                    may be increased by the fact that futures contracts in which
                    the Fund may invest are taxable securities rather than
                    tax-exempt securities. The prices of taxable securities may
                    not move in a similar manner to prices of tax-exempt
                    securities.
 
                    YEAR 2000. The Fund could be adversely affected if the
                    computer systems necessary for the efficient operation of
                    the Investment Manager, the Fund's other service providers
                    and the markets and individual and governmental issuers in
                    which the Fund invests do not properly process and calculate
                    date-related information from and after January 1, 2000.
                    While year 2000-related computer problems could have a
                    negative effect on the Fund, the Investment Manager and
                    affiliates are working hard to avoid any problems and to
                    obtain assurances from their service providers that they are
                    taking similar steps.

                    Joseph R. Arcieri, Vice President of the Investment Manager
                    and a member of the Investment Manager'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 with the
                    Investment Manager for over five years.
 
                    The Fund pays the Investment Manager a monthly management
                    fee as full compensation for the services and facilities
                    furnished to the Fund, and for Fund expenses assumed by the
                    Investment Manager. The fee is based on the Fund's average
                    daily net assets. For the fiscal year ended December 31,
                    1998, the Fund accrued total compensation to the Investment
                    Manager amounting to 0.53% of the Fund's average daily net
                    assets.
 
                                                                               7

SHAREHOLDER INFORMATION
 
                    PRICING FUND SHARES
- --------------------------------------------------------------------------------
                    The price of Fund shares (excluding sales charges), called
                    "net asset value," is based on the value of the Fund's
                    portfolio securities. While the assets of each Class are
                    invested in a single portfolio of securities, the net asset
                    value of each Class will differ because the Classes have
                    different ongoing distribution fees.
 
                    The net asset value per share of the Fund is determined once
                    daily at 4:00 p.m. Eastern time on each day that the New
                    York Stock Exchange is open (or, on days when the New York
                    Stock Exchange closes prior to 4:00 p.m., at such earlier
                    time). Shares will not be priced on days that the New York
                    Stock Exchange is closed.
 
                    The value of the Fund's portfolio securities (except for
                    short-term taxable debt securities and certain other
                    investments) are valued by an outside independent pricing
                    service. The service uses a computerized grid matrix of
                    tax-exempt securities and its evaluations in determining
                    what it believes is the fair value of the portfolio
                    securities. The Fund's Board of Trustees believes that
                    timely and reliable market quotations are generally not
                    readily available to the Fund to value tax-exempt securities
                    and the valuations that the pricing service supplies are
                    more likely to approximate the fair value of the securities.
 
                    An exception to the Fund's general policy of using market
                    prices concerns its short-term debt portfolio securities.
                    Debt securities with remaining maturities of sixty days or
                    less at the time of purchase are valued at amortized cost.
                    However, if the cost does not reflect the securities' market
                    value, these securities will be valued at their fair value.
 
                    HOW TO BUY SHARES
- --------------------------------------------------------------------------------
                    You may open a new account to buy Fund shares or buy
                    additional Fund shares for an existing account by contacting
                    your Morgan Stanley Dean Witter Financial Advisor or other
                    authorized financial representative. Your Financial Advisor
                    will assist you, step-by-step, with the procedures to invest
                    in the Fund. You may also purchase shares directly by
                    calling the Fund's transfer agent and requesting an
                    application.
 
                    Because every investor has different immediate financial
                    needs and long-term investment goals, the Fund offers
                    investors four Classes of shares: Classes A, B, C and D.
                    Class D shares are only offered to a limited group of
                    investors. Each Class of shares offers a distinct structure
                    of sales charges, distribution and service fees, and other
                    features that are designed to address a variety of needs.
                    Your Financial Advisor or other authorized financial
                    representative can help you decide which Class may be most
                    appropriate for you. When purchasing Fund shares, you must
                    specify which Class of shares you wish to purchase.
 
                    When you buy Fund shares, the shares are purchased at the
                    next share price calculated, less any applicable front-end
                    sales charge, after we receive your investment order in
                    proper form. We reserve the right to reject any order for
                    the purchase of Fund shares.

                    Class of the Fund for the same Class of any other
                    continuously offered Multi-Class Fund, or for shares of a
                    No-Load Fund, Money Market Fund or Short-Term U.S. Treasury
                    Trust, without the imposition of an exchange fee. See the
                    inside back cover of this PROSPECTUS for each Morgan Stanley
                    Dean Witter Fund's designation as a Multi-Class Fund, No-
                    Load Fund or Money Market Fund. If a Morgan Stanley Dean
                    Witter Fund is not listed, consult the inside back cover of
                    that Fund's PROSPECTUS for its designation. For purposes of
                    exchanges, shares of FSC Funds (subject to a front-end sales
                    charge) are treated as Class A shares of a Multi-Class Fund.
 
                                                                               9
<PAGE>
                    Exchanges may be made after shares of the Fund acquired by
                    purchase have been held for thirty days. There is no waiting
                    period for exchanges of shares acquired by exchange or
                    dividend reinvestment. The current PROSPECTUS for each fund
                    describes its investment objective and policies and should
                    be read before investment.
 
                    EXCHANGE PROCEDURES. You can process an exchange by
                    contacting your Morgan Stanley Dean Witter Financial Advisor
                    or other authorized financial representative. Otherwise, you
                    must forward an exchange privilege authorization form to the
                    Fund's transfer agent - Morgan Stanley Dean Witter Trust FSB
                    - and then write the transfer agent or call (800) 869-NEWS
                    to place an exchange order. You can obtain an exchange
                    privilege authorization form by contacting your Financial
                    Advisor or other authorized financial representative, or by
                    calling (800) 869-NEWS. If you hold share certificates, no
                    exchanges may be processed until we have received all
                    applicable share certificates.
 
                    An exchange to any Morgan Stanley Dean Witter Fund (except a
                    Money Market Fund) is made on the basis of the next
                    calculated net asset values of the Funds involved after the
                    exchange instructions are accepted. When exchanging into a
                    Money Market Fund, the Fund's shares are sold at their next
                    calculated net asset value and the Money Market Fund's
                    shares are purchased at their net asset value on the
                    following business day.
 
                    The Fund may terminate or revise the exchange privilege upon
                    required notice. Certain services normally available to
                    shareholders of Money Market Funds, including the check
                    writing privilege, are not available for Money Market Fund
                    shares you acquire in an exchange.
 
                    TELEPHONE EXCHANGES. For your protection when calling Morgan
                    Stanley Dean Witter Trust FSB, we will employ reasonable
                    procedures to confirm that exchange instructions
                    communicated over the telephone are genuine. These
                    procedures may include requiring various forms of personal
                    identification such as name, mailing address, social
                    security or other tax identification number. Telephone
                    instructions also may be recorded.
 
                    Telephone instructions will be accepted if received by the
                    Fund's transfer agent between 9:00 a.m. and 4:00 p.m.
                    Eastern time, on any day the New York Stock Exchange is open
                    for business. 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 Fund in the past.
 
                    MARGIN ACCOUNTS. If you have pledged your Fund shares in a
                    margin account, contact your Morgan Stanley Dean Witter
                    Financial Advisor or other authorized financial
                    representative regarding restrictions on the exchange of
                    such shares.
 
                    TAX CONSIDERATIONS OF EXCHANGES. If you exchange shares of
                    the Fund for shares of another Morgan Stanley Dean Witter
                    Fund there are important tax considerations. For tax
                    purposes, the exchange out of the Fund is considered a sale
                    of Fund shares - and the exchange into the other Fund is
                    considered a purchase. As a result, you may realize a
                    capital gain or loss.
 
                    You should review the "Tax Consequences" section and consult
                    your own tax professional about the tax consequences of an
                    exchange.
 
                    FREQUENT EXCHANGES. A pattern of frequent exchanges may
                    result in the Fund limiting or prohibiting, at its
                    discretion, additional purchases and/or exchanges. The Fund
                    will notify you in advance of limiting your exchange
                    privileges.

 Systematic         If your investment in all of the Morgan Stanley Dean Witter
 Withdrawal Plan    Family of Funds has a total market value of at least
 ICON               $10,000, you may elect to withdraw amounts of $25 or more,
                    or in any whole percentage of a Fund's balance (provided the
                    amount is at least $25), on a monthly, quarterly,
                    semi-annual or annual basis, from any Fund with a balance of
                    at least $1,000. Each time you add a Fund to the plan, you
                    must meet the plan requirements.
                    ------------------------------------------------------------
                    Amounts withdrawn are subject to any applicable CDSC. A CDSC
                    may be waived under certain circumstances. See the Class B
                    waiver categories listed in the "Share Class Arrangements"
                    section of this PROSPECTUS.
                    ------------------------------------------------------------
                    To sign up for the Systematic Withdrawal Plan, contact your
                    Morgan Stanley Dean Witter Financial Advisor or call (800)
                    869-NEWS. You may terminate or suspend your plan at any
                    time. Please remember that withdrawals from the plan are
                    sales of shares, not Fund "distributions," and ultimately
                    may exhaust your account balance. The Fund may terminate or
                    revise the plan at any time.

                    PAYMENT FOR SOLD SHARES. After we receive your complete
                    instructions to sell as described above, a check will be
                    mailed to you within seven days, although we will attempt to
                    make payment within one business day. Payment may also be
                    sent to your brokerage account.
 
                    Payment may be postponed or the right to sell your shares
                    suspended under unusual circumstances. If you request to
                    sell shares that were recently purchased by check, payment
                    of the sale proceeds may be delayed for the minimum time
                    needed to verify that the check has been honored (not more
                    than fifteen days from the time we receive the check).
 
                    REINSTATEMENT PRIVILEGE. If you sell Fund shares and have
                    not previously exercised the reinstatement privilege, you
                    may, within 35 days after the date of sale, invest any
                    portion of the proceeds in the same Class of Fund shares at
                    their net asset value and receive a pro rata credit for any
                    CDSC paid in connection with the sale.
 
                    INVOLUNTARY SALES. The Fund reserves the right, on sixty
                    days' notice, to sell the shares of any shareholder (other
                    than shares held in an IRA or 403(b) Custodial Account)
                    whose shares, due to sales by the shareholder, have a value
                    below $100, or in the case of an account opened through
                    EASYINVEST-SM-, if after 12 months the shareholder has
                    invested less than $1,000 in the account.
 
                    However, before the Fund sells your shares in this manner,
                    we will notify you and allow you sixty days to make an
                    additional investment in an amount that will increase the
                    value of your account to at least the required amount before
                    the sale is processed. No CDSC will be imposed on any
                    involuntary sale.
 
                    MARGIN ACCOUNTS. Certain restrictions may apply to Fund
                    shares pledged in margin accounts with Dean Witter Reynolds
                    or another authorized broker-dealer of Fund shares. If you
                    hold Fund shares in this manner, please contact your Morgan
                    Stanley Dean Witter Financial Advisor or other authorized
                    financial representative for more details.

                    DISTRIBUTIONS
- --------------------------------------------------------------------------------
                    The Fund passes substantially all of its earnings from
                    income and capital gains along to its investors as
                    "distributions." The Fund earns interest from fixed-income
                    investments. These amounts are passed along to Fund
                    shareholders as "income dividend distributions." The Fund
                    realizes capital gains whenever it sells securities for a
                    higher price than it paid for them. These amounts may be
                    passed along as "capital gain distributions."
 
                    The Fund declares income dividends separately for each
                    Class. Distributions paid on Class A and Class D shares will
                    be higher than for Class B and Class C because distribution
                    fees that Class B and Class C pay are higher. Normally,
                    income dividends are distributed to shareholders monthly and
                    capital gains are distributed annually in December. The
                    Fund, however, may retain and reinvest any long-term capital
                    gains. The Fund may at times make payments from sources
                    other than income or capital gains that represent a return
                    of a portion of your investment.
 
                    Distributions are reinvested automatically in additional
                    shares of the same Class and automatically credited to your
                    account, unless you request in writing that all
                    distributions be paid in cash. If you elect the cash option,
                    the Fund will mail a check to you no later than seven
                    business days after the distribution is declared. No
                    interest will accrue on uncashed checks. If you wish to
                    change how your distributions are paid, your request should
                    be received by the Fund's transfer agent, Morgan Stanley
                    Dean Witter Trust FSB, at least five business days prior to
                    the record date of the distributions.
 
                    TAX CONSEQUENCES
- --------------------------------------------------------------------------------
                    As with any investment, you should consider how your Fund
                    investment will be taxed. The tax information in this
                    PROSPECTUS is provided as general information. You should
                    consult your own tax professional about the tax consequences
                    of an investment in the Fund.
 
                    You need to be aware of the possible tax consequences when:
 
                    - The Fund makes distributions; and
 
                    - You sell Fund shares, including an exchange to another
                      Morgan Stanley Dean Witter Fund.
 
                    TAXES ON DISTRIBUTIONS. Your income dividend distributions
                    are normally exempt from federal and California's personal
                    income taxes -- to the extent they are derived from
                    California's municipal obligations. Income derived from
                    other portfolio securities may be subject to federal, state
                    and/or local income taxes.
 
                    Income derived from some municipal securities is subject to
                    the federal "alternative minimum tax." Certain tax-exempt
                    securities whose proceeds are used to finance private,
                    for-profit organizations are subject to this special tax
                    system that ensures that individuals pay at least some
                    federal taxes. Although interest on these securities is
                    generally exempt from federal income tax, some taxpayers who
                    have many tax deductions or exemptions nevertheless may have
                    to pay tax on the income.
 
                                                                              13
<PAGE>
                    If you borrow money to purchase shares of the Fund, the
                    interest on the borrowed money is generally not deductible
                    for personal income tax purposes.
 
                    If the Fund makes any capital gain distributions, those
                    distributions will normally be subject to federal and
                    California income tax when they are paid, whether you take
                    them in cash or reinvest them in the Fund shares. Any
                    long-term capital gain distributions are taxable to you as
                    long-term capital gains, no matter how long you have owned
                    shares in the Fund.
 
                    Every January, you will be sent a statement (IRS Form
                    1099-DIV) showing the taxable distributions paid to you in
                    the previous year. The statement provides full information
                    on your dividends and capital gains for tax purposes.
 
                    TAXES ON SALES. Your sale of Fund shares normally is subject
                    to federal and state income tax and may result in a taxable
                    gain or loss to you. A sale also may be subject to local
                    income tax. Your exchange of Fund shares for shares of
                    another Morgan Stanley Dean Witter Fund is treated for tax
                    purposes like a sale of your original shares and a purchase
                    of your new shares. Thus, the exchange may, like a sale,
                    result in a taxable gain or loss to you and will give you a
                    new tax basis for your new shares.
 
                    When you open your Fund account, you should provide your
                    social security or tax identification number on your
                    investment application. By providing this information, you
                    will avoid being subject to a federal backup withholding tax
                    of 31% on taxable distributions and redemption proceeds. Any
                    withheld amount would be sent to the IRS as an advance tax
                    payment.
 
                    SHARE CLASS ARRANGEMENTS
- --------------------------------------------------------------------------------
                    The Fund offers several Classes of shares having different
                    distribution arrangements designed to provide you with
                    different purchase options according to your investment
                    needs. Your Morgan Stanley Dean Witter Financial Advisor or
                    other authorized financial representative can help you
                    decide which Class may be appropriate for you.
 
                    The general public is offered three Classes: Class A shares,
                    Class B shares and Class C shares, which differ principally
                    in terms of sales charges and ongoing expenses. A fourth
                    Class, Class D shares, is offered only to a limited category
                    of investors. Shares that you acquire through reinvested
                    distributions will not be subject to any front-end sales
                    charge or CDSC - contingent deferred sales charge. Sales
                    Personnel may receive different compensation for selling
                    each Class of shares. The sales charges applicable to each
                    Class provide for the distribution financing of shares of
                    that Class.

FRONT-END SALES CHARGE OR FSC
An initial sales charge you pay when purchasing Class A shares that is based on
a percentage of the offering price. The percentage declines based upon the
dollar value of Class A shares you purchase. We offer three ways to reduce your
Class A sales charges - the COMBINED PURCHASE PRIVILEGE, RIGHT OF ACCUMULATION
and LETTER OF INTENT.

</TABLE>
 
                     CLASS A SHARES  Class A shares are sold at net asset value
                    plus an initial sales charge of up to 4.25%. The initial
                    sales charge is reduced for purchases of $25,000 or more
                    according to the schedule below. Investments of $1 million
                    or more are not subject to an initial sales charge, but are
                    generally subject to a contingent deferred sales charge, or
                    CDSC, of 1.0% on sales made within one year after the last
                    day of the month of purchase. The CDSC will be assessed in
                    the same manner and with the same CDSC waivers as with Class
                    B shares. Class A shares are also subject to a distribution
                    (12b-1) fee of up to 0.25% of the average daily net assets
                    of the Class.
 
                    The offering price of Class A shares includes a sales charge

                    of sales charges if the cumulative net asset value of Class
                    A shares of the Fund purchased in a single transaction,
                    together with shares of other Funds you currently own which
                    were previously purchased at a price including a front-end
                    sales charge (including shares acquired through reinvestment
                    of distributions), amounts to $25,000 or more. Also, if you
                    have a cumulative net asset value of all your Class A and
                    Class D shares equal to at least $5 million (or $25 million
                    for certain employee benefit plans), you are eligible to
                    purchase Class D shares of any Fund subject to the Fund's
                    minimum initial investment requirement.
 
                    You must notify your Morgan Stanley Dean Witter Financial
                    Advisor or other authorized financial representative (or
                    Morgan Stanley Dean Witter Trust FSB if you purchase
                    directly through the Fund), 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 when an order is placed by mail. The
                    reduced sales charge will not be granted if: (i)
                    notification is not furnished at the time of the order; or
                    (ii) a review of the records of Dean Witter Reynolds or
                    other authorized dealer of Fund shares or the Fund's
                    transfer agent does not confirm your represented holdings.
 
                    LETTER OF INTENT. The schedule of reduced sales charges for
                    larger purchases also will be available to you if you enter
                    into a written "letter of intent." A letter of intent
                    provides for the purchase of shares within a thirteen-month
                    period. It is available for purchases of Class A shares of
                    Multi-Class Funds and/or shares of FSC Funds. The initial
                    purchase under a letter of intent must be at least 5% of the
                    stated investment goal. To determine the applicable sales
                    charge reduction, you may also include: (1) the cost of
                    shares of other Morgan Stanley Dean Witter Funds which were
                    previously purchased at a price including a front-end sales
                    charge during the 90-day period prior to the distributor
                    receiving the letter of intent, and (2) the cost of shares
                    of other Funds you currently own acquired in exchange for
                    shares of Funds purchased during that period at a price
                    including a front-end sales charge. You can obtain a letter
                    of intent by contacting your Morgan Stanley Dean Witter
                    Financial Advisor or other authorized financial
                    representative, or by calling (800) 869-NEWS. If you do not
                    achieve the stated investment goal within the thirteen-month
                    period, you are required to pay the difference between the
                    sales charges otherwise applicable and sales charges
                    actually paid.
 
                    OTHER FRONT-END SALES CHARGE WAIVERS. In addition to
                    investments of $1 million or more, your purchase of Class A
                    shares is not subject to a front-end sales charge (or a CDSC
                    upon sale) if your account qualifies under one of the
                    following categories:
 
                    - A trust for which Morgan Stanley Dean Witter Trust FSB
                      provides discretionary trustee services.

                      proprietary mutual fund of that Financial Advisor's
                      previous firm that imposed either a front-end or deferred

                      (1) you sold the shares not more than 60 days prior to
                      purchase, and (2) the sale proceeds were maintained in the

                    value with no initial sales charge but are subject to a
                    contingent deferred sales charge, or CDSC, as set forth in
                    the table below. For the purpose of calculating the CDSC,

                    Each time you place an order to sell or exchange shares,
                    shares with no CDSC will be sold or exchanged first, then
                    shares with the lowest CDSC will be sold or exchanged next.
                    For any shares subject to a CDSC, the CDSC will be assessed
                    on an amount equal to the lesser of the current market value
                    or the cost of the shares being sold.
 
                    CDSC WAIVERS. A CDSC, if otherwise applicable, will be
                    waived in the case of:
 
                    - Sales of shares held at the time you die or become
                      disabled (within the definition in Section 72(m)(7) of the
                      Internal Revenue Code which relates to the ability to
                      engage in gainful employment), if the shares are: (i)
                      registered either in your name (not a trust) or in the
                      names of you and your spouse as joint tenants with right
                      of survivorship; or (ii) held in a qualified corporate or
                      self-employed
 
                                                                              17

                      retirement plan, IRA or 403(b) Custodial Account, provided
                      in either case that the sale is requested within one year
                      of your death or initial determination of disability.
 
                    - Sales in connection with the following retirement plan
                      "distributions": (i) 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); (ii) distributions from an IRA or 403(b) Custodial
                      Account following attainment of age 59 1/2; or (iii) a
                      tax-free return of an excess IRA contribution (a
                      "distribution" does not include a direct transfer of IRA,
                      403(b) Custodial Account or retirement plan assets to a
                      successor custodian or trustee).
 
                    - Sales of shares in connection with the Systematic
                      Withdrawal Plan of up to 12% annually of the value of each
                      Fund from which plan sales are made. The percentage is
                      determined on the date you establish the Systematic
                      Withdrawal Plan and based on the next calculated share
                      price. You may have this CDSC waiver applied in amounts up
                      to 1% per month, 3% per quarter, 6% semi-annually or 12%
                      annually. Shares with no CDSC will be sold first, followed
                      by those with the lowest CDSC. As such, the waiver benefit
                      will be reduced by the amount of your shares that are not
                      subject to a CDSC. If you suspend your participation in
                      the plan, you may later resume plan payments without
                      requiring a new determination of the account value for the
                      12% CDSC waiver.
 
                    All waivers will be granted only following the Distributor
                    receiving confirmation of your entitlement. If you believe
                    you are eligible for a CDSC waiver, please contact your
                    Financial Advisor or call (800) 869-NEWS.
 
                    DISTRIBUTION FEE. Class B shares are also subject to an
                    annual distribution (12b-1) fee of up to 0.75% of the lesser
                    of: (a) the average daily aggregate gross purchases by all
                    shareholders 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
                    sold by all shareholders since the Fund's inception upon
                    which a CDSC has been imposed or waived, or (b) the average
                    daily net assets of Class B.
 
                    CONVERSION FEATURE. After ten (10) years, Class B shares
                    will convert automatically to Class A shares of the Fund
                    with no initial sales charge. The ten year period runs 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, from the last day of the month in which the
                    original Class B shares were purchased; the shares will
                    convert to Class A shares based on their relative net asset
                    values in the month following the ten year period. At the
                    same time, an equal proportion of Class B shares acquired
                    through automatically reinvested distributions will convert
                    to Class A shares on the same basis. (Class B shares held
                    before May 1, 1997, however, will convert to Class A shares
                    in May 2007.)
 
                    Currently, the Class B share conversion is not a taxable
                    event; the conversion feature may be cancelled if it is
                    deemed a taxable event in the future by the Internal Revenue
                    Service.

<PAGE>
                    If you exchange your Class B shares for shares of a Money
                    Market Fund, No-Load Fund or Short-Term U.S. Treasury Trust,
                    the holding period for conversion is frozen as of the last
                    day of the month of the exchange and resumes on the last day
                    of the month you exchange back into Class B shares.
 
                    EXCHANGING SHARES SUBJECT TO A CDSC. There are special
                    considerations when you exchange Fund shares that are
                    subject to a CDSC. When determining the length of time you
                    held the shares and the corresponding CDSC rate, any period
                    (starting at the end of the month) during which you held
                    shares of a fund that does NOT charge a CDSC WILL NOT BE
                    COUNTED. Thus, in effect the "holding period" for purposes
                    of calculating the CDSC is frozen upon exchanging into a
                    fund that does not charge a CDSC.
 
                    For example, if you held Class B shares of the Fund for one
                    year, exchanged to Class B of another Morgan Stanley Dean
                    Witter Multi-Class Fund for another year, then sold your
                    shares, a CDSC rate of 4% would be imposed on the shares
                    based on a two year holding period -- one year for each
                    Fund. However, if you had exchanged the shares of the Fund
                    for a Money Market Fund (which does not charge a CDSC)
                    instead of the Multi-Class Fund, then sold your shares, a
                    CDSC rate of 5% would be imposed on the shares based on a
                    one year holding period. The one year in the Money Market
                    Fund would not be counted. Nevertheless, if shares subject
                    to a CDSC are exchanged for a Fund that does not charge a
                    CDSC, you will receive a credit when you sell the shares
                    equal to the distribution (12b-1) fees you paid on those
                    shares while in that Fund up to the amount of any applicable
                    CDSC.
 
                    In addition, shares that are exchanged into or from a Morgan
                    Stanley Dean Witter Fund subject to a higher CDSC rate will
                    be subject to the higher rate, even if the shares are
                    re-exchanged into a Fund with a lower CDSC rate.
 
                     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 sales made within one year after the last day of the
                    month of purchase. The CDSC will be assessed in the same
                    manner and with the same CDSC waivers as with Class B
                    shares.
 
                    DISTRIBUTION FEE. Class C shares are subject to an annual
                    distribution (12b-1) fee of 0.75% of the average daily net
                    assets of that Class. 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. Unlike Class B
                    shares, Class C shares have no conversion feature and,
                    accordingly, an investor that purchases Class C shares may
                    be subject to distribution (12b-1) fees applicable to Class
                    C shares for an indefinite period.
 
                                                                              19

                     CLASS D SHARES  Class D shares are offered without any
                    sales charge on purchases or sales and without any
                    distribution (12b-1) fee. Class D shares are offered only to
                    investors meeting an initial investment minimum of $5
                    million and the following investor categories:
 
                    - Investors participating in the Investment Manager's mutual
                      fund asset allocation program (subject to all of its terms

                    MEETING CLASS D ELIGIBILITY MINIMUMS. To meet the $5 million
                    initial investment to qualify to purchase Class D shares you
                    may combine: (1) purchases in a single transaction of Class
                    D shares of the Fund and other Morgan Stanley Dean Witter
                    Multi-Class Funds and/or (2) previous purchases of Class A
                    and Class D shares of Multi-Class Funds and shares of FSC
                    Funds you currently own, along with shares of Morgan Stanley
                    Dean Witter Funds you currently own that you acquired in
                    exchange for those shares.
 
                     NO SALES CHARGES FOR REINVESTED CASH DISTRIBUTIONS  If you
                    receive a cash payment representing an income dividend or
                    capital gain and you reinvest that amount in the applicable
                    Class of shares by returning the check within 30 days of the
                    payment date, the purchased shares would not be subject to
                    an initial sales charge or CDSC.
 
                     PLAN OF DISTRIBUTION (RULE 12B-1 FEES)  The Fund has
                    adopted a Plan of Distribution in accordance with Rule 12b-1
                    under the Investment Company Act of 1940 with respect to the
                    distribution of Class A, Class B and Class C shares. The
                    Plan allows the Fund to pay distribution fees for the sale
                    and distribution of these shares. It also allows the Fund to
                    pay for services to shareholders of Class A, Class B and
                    Class C shares. Because these fees are paid out of the
                    Fund's assets on an ongoing basis, over time these fees will
                    increase the cost of your investment in these Classes and
                    may cost you more than paying other types of sales charges.

I. FUND HISTORY
- --------------------------------------------------------------------------------
 
    The Fund was organized under the laws of the Commonwealth of Massachusetts
on April 9, 1984 as a Massachusetts business trust under the name Dean Witter
California Tax-Free Income Fund. Effective June 22, 1998, the Fund's name was
changed to Morgan Stanley Dean Witter California Tax-Free Income Fund.
 
II. DESCRIPTION OF THE FUND AND ITS INVESTMENTS AND RISKS
- --------------------------------------------------------------------------------
 
A. CLASSIFICATION
 
    The Fund is an open-end, diversified management investment company whose
investment objective is to provide a high level of current income exempt from
both federal and California income tax, consistent with the preservation of
capital.
 
B. INVESTMENT STRATEGIES AND RISKS
 
    The following discussion of the Fund's investment strategies and risks
should be read with the sections of the Fund's PROSPECTUS titled "Principal
Investment Strategies," "Principal Risks," "Additional Investment Strategy
Information" and "Additional Risk Information."
 
    TAXABLE SECURITIES.  The Fund may invest up to 20% of its total assets in
taxable money market instruments, tax-exempt securities of other states and
municipalities and 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 the sale of the Fund's
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 tax-exempt securities of other states which
satisfy the standards established for the tax-exempt securities of the state of
California 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 Investors Services, 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.
 
    VARIABLE RATE AND FLOATING RATE OBLIGATIONS.  The Fund may invest in
Municipal Bonds and Municipal Notes ("Municipal Obligations") of the type called
variable rate. 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 issue 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 an obligation prior to maturity, is
enhanced.
 
    FUTURES CONTRACTS AND OPTIONS ON FUTURES.  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 on 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.
 
                                       4
<PAGE>
    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 a loss. Similarly, the closing out of a futures contract
purchase is effected by the Fund entering into a futures contract sale. If the
offsetting sale price exceeds the purchase price, the Fund realizes a gain, and
if the offsetting sale price is less than the purchase price, the Series
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 (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 contract is lost. Since the value of the option is fixed as 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 change is reflected in the net asset value of the particular Series
holding the options.
 
    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, Bank
Certificates of Deposit and on a municipal bond index. 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.
A risk in employing 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 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 Investment 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 the 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 characteristics similar to Exchange traded 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 such a market will develop.
 
                                       5
<PAGE>
    The Fund may not enter into futures contracts or related options thereon if,
immediately thereafter, the amount committed to margin plus the amount paid for
option premiums exceeds 5% of the value of the Fund's total assets. In instances
involving the purchase of futures contracts by the Fund, an amount equal to the
market value of the futures contract will be deposited in a segregated account
of cash and cash equivalents or other liquid portfolio securities 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 the net assets of the
Fund would be hedged.
 
    MUNICIPAL BOND INDEX FUTURES.  The Fund may utilize municipal bond index
futures contracts for hedging purposes. The 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.
 
    OPTIONS.  The Fund may purchase or sell (write) options on debt securities
as a means of achieving additional return or hedging the value of a Series'
portfolio. The Fund will 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.
 
    Presently there are no options on California tax-exempt securities traded on
national securities exchanges. The Fund will not invest in options on debt
securities in the coming year or until such time as they become available on
national securities exchanges.
 
    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 listed on
national exchanges. The Fund may not write covered options in an amount
exceeding 20% of the value of the total assets of the Fund. A call option is
"covered" if the Fund owns the underlying security covered by the call or has an
absolute and immediate right to acquire that security 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
 
                                       6
<PAGE>
position by effecting a closing sale transaction. This is accomplished by
selling an option of the same fund as the option previously purchased. There can
be no assurance that either a closing purchase or sale transaction on behalf of
the Fund 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 purchase of a call
option may also be wholly or partially offset by unrealized appreciation of the
underlying security. If a put option written by the Fund is exercised, the Fund
may incur a loss equal to the difference between the exercise price of the
option and the sum of the sale price of the underlying security plus the
premiums received from the sale of the option. Other principal factors affecting
the market value of a put or a call option include supply and demand, interest
rates, the current market price and price volatility of the underlying security
and the time remaining until the expiration date.
 
    An option position may be closed out only on an exchange which provides a
secondary market for an option of the same series. Although the Fund will
generally purchase or write only those options for which there appears to be an
active secondary market, there is no assurance that a liquid secondary market on
an exchange will exist for any particular option. In such event, it might not be
possible to effect closing transactions in particular options, so that the Fund
would have to exercise its options in order to realize any profit and would
incur brokerage commission upon the exercise of call options and upon 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.
 
    REPURCHASE AGREEMENTS.  The Fund may invest in repurchase agreements. When
cash may be available for only a few days, it may be invested by the Fund in
repurchase agreements until such time as it may otherwise be invested or used
for payments of obligations of the Fund. These agreements, which may be viewed
as a type of secured lending by the Fund, typically involve the acquisition by
the Fund of debt securities from a selling financial institution such as a bank,
savings and loan association or broker-dealer. The agreement provides that the
Fund will sell back to the institution, and that the institution will
repurchase, the underlying security serving as collateral at a specified price
and at a fixed time in the future, usually not more than seven days from the
date of purchase. The collateral will be marked-to-market daily to determine
that the value of the collateral, as specified in the agreement, does not
decrease below the purchase price plus accrued interest. If such decrease
occurs, additional collateral will be requested and, when received, added to the
account to maintain full collateralization. The Fund will accrue interest form
the institution until the time when the repurchase is to occur. Although this
date is deemed by the Fund to be the maturity date of a repurchase agreement,
the maturities of securities subject to repurchase agreements are not subject to
any limits.
 
    While repurchase agreements involve certain risks not associated with direct
investments in debt securities, the Fund follows procedures designed to minimize
such risks. These procedures include effecting repurchase transactions only with
large, well-capitalized and well-established financial institutions whose
financial condition will be continually monitored by the Investment Manager
subject to procedures established by the Trustees. In addition, as described
above, the value of the collateral underlying the repurchase agreement will be
at least equal to the repurchase price, including any accrued interest earned on
the repurchase agreement. In the event of a default or bankruptcy by a selling
financial institution, the Fund will seek to liquidate such collateral. However,
the exercising of the Fund's right to liquidate such collateral could involve
certain costs or delays and, to the extent that proceeds form any sale upon a
default of the obligation to repurchase were less than the repurchase price, the
Fund could suffer a loss.
 
    LENDING PORTFOLIO SECURITIES.  The Fund may lend its portfolio securities to
brokers, dealers and other financial institutions, provided that the loans are
callable at any time by the Fund, and are at all
 
                                       7
<PAGE>
times secured by cash or cash equivalents, which are maintained in a segregated
account pursuant to applicable regulations and that are equal to at least 100%
of the market value, determined daily, of the loaned securities. The advantage
of these loans is that the Fund continues to receive the income on the loaned
securities while at the same time earning interest on the cash amounts deposited
as collateral, which will be invested in short-term obligations. The Fund will
not lend its portfolio securities if such loans are not permitted by the laws or
regulations of any state in which its shares are qualified for sale and will not
lend more than 25% of the value of its total assets.
 
    As with any extensions of credit, there are risks of delay in recovery and,
in some cases, even loss of rights in the collateral should the borrower of the
securities fail financially. However, these loans of portfolio securities will
only be made to firms deemed by the Fund's management to be creditworthy and
when the income which can be earned from such loans justifies the attendant
risks. Upon termination of the loan, the borrower is required to return the
securities to the Fund. Any gain or loss in the market price during the loan
period would inure to the Fund.
 
    When voting or consent rights which accompany loaned securities pass to the
borrower, the Fund will follow the policy of calling the loaned securities, to
be delivered within one day after notice, to permit the exercise of the rights
if the matters involved would have a material effect on the Fund's investment in
the loaned securities. The Fund will pay reasonable finder's, administrative and
custodial fees in connection with a loan of its securities.
 
    WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS.  From
time to time 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 these 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 commitment. 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. The securities so purchased or sold are subject
to market fluctuation and no interest or dividends accrue to the purchaser prior
to the settlement date.
 
    At the time the Fund makes the commitment to purchase or sell securities on
a when-issued, delayed delivery or forward commitment basis, it will record the
transaction and thereafter reflect the value, each day, of such security
purchased, or if a sale, the proceeds to be received, in determining its net
asset value. At the time of delivery of the securities, their value may be more
or less than the purchase or sale price. 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 its net
asset value. The Fund will also establish a segregated account on the Fund's
books in which it will continually maintain cash or cash equivalents or other
liquid portfolio securities equal in value to commitments to purchase securities
on a when-issued, delayed delivery or forward commitment basis.
 
    WHEN, AS AND IF ISSUED SECURITIES.  The Fund may purchase securities on a
"when, as and if issued" basis under which the issuance of the security depends
upon the occurrence of a subsequent event, such as approval of a merger,
corporate reorganization or debt restructuring. The commitment for the purchase
of any such security will not be recognized in the portfolio of the Fund until
the Investment Manager determines that issuance of the security is probable. At
that time, the Fund will record the transaction and, in determining its net
asset value, will reflect the value of the security daily. At that time, the
Fund will also establish a segregated account on the Fund's books in which it
will maintain cash or cash equivalents or other liquid portfolio securities
equal in value to recognized commitments for such securities.
 
    The value of the Fund's commitments to purchase the securities of any one
issuer, together with the value of all securities of such issuer owned by the
Fund, may not exceed 5% of the value of the Fund's total assets at the time the
initial commitment to purchase such securities is made. An increase in the
percentage of the Fund's [total or net] assets committed to the purchase of
securities on a "when, as
 
                                       8
<PAGE>
and if issued" basis may increase the volatility of its net asset value. The
Fund may also sell securities on a "when, as and if issued" basis provided that
the issuance of the security will result automatically from the exchange or
conversion of a security owned by the Fund at the time of sale.
 
    YEAR 2000.  The investment management services provided to the Fund by the
Investment Manager and the services provided to shareholders by the Distributor
and the Transfer Agent depend on the smooth functioning of their computer
systems. Many computer software systems in use today cannot recognize the year
2000, but revert to 1900 or some other date, due to the manner in which dates
were encoded and calculated. That failure could have a negative impact on the
handling of securities trades, pricing and account services. The Investment
Manager, the Distributor and the Transfer Agent have been actively working on
necessary changes to their own computer systems to prepare for the year 2000 and
expect that their systems will be adapted before that date, but there can be no
assurance that they will be successful, or that interaction with other
non-complying computer systems will not impair their services at that time.
 
    In addition, it is possible that the markets for securities in which the
Fund invests may be detrimentally affected by computer failures throughout the
financial services industry beginning January 1, 2000. Improperly functioning
trading systems may result in settlement problems and liquidity issues. In
addition, corporate and governmental data processing errors may result in
production problems for individual companies and overall economic uncertainties.
Earnings of individual issuers will be affected by remediation costs, which may
be substantial and may be reported inconsistently in U.S. and foreign financial
statements. Accordingly, the Fund's investments may be adversely affected.
 
THE STATE OF CALIFORNIA--SPECIAL INVESTMENT CONSIDERATIONS
 
    The following describes certain risks with respect to municipal obligations
of California issuers in which the Fund may invest. This summarized information
is based on information drawn from official statements and prospectuses relating
to securities offerings of the State of California and other public documents
available as of the date of this Statement of Additional Information. Although
the Investment Manager has not independently verified such information, it has
no reason to believe that such information is not correct in all material
respects.
 
    The Fund will be affected by any political, economic or regulatory
developments affecting the ability of California issuers to pay interest or
repay principal. Provisions of 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. Future California political and economic developments,
constitutional amendments, legislative measures, executive orders,
administrative regulations, litigation and voter initiatives could have an
adverse effect on the debt obligations of California issuers.
 
    Certain debt obligations held by the Fund may be obligations of issuers
which rely in whole or in substantial part on California state revenues for the
continuance of their operations and payment of their obligations. Whether and to
what extent the California Legislature will continue to appropriate a portion of
the State's General Fund to counties, cities and their various entities, is not
entirely certain. To the extent local entities do not receive money from the
State to pay for their operations and services, their ability to pay debt
service on obligations held by the Fund may be impaired.
 
    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,
 
                                       9
<PAGE>
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 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
 
                                       10
<PAGE>
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 (i) 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.
 
    Certain tax-exempt securities in which the Fund may invest may be
obligations payable solely from the revenues of specific institutions, or may be
secured by specific properties, which are subject to provisions of California
law which could adversely affect the holders of such obligations. For example,
the revenues of California health care institutions may be subject to state
laws, and California law limits the remedies of a creditor secured by a mortgage
or deed of trust on real property.
 
    California is the most populous state in the nation with a total population
estimated at 32.9 million. The State now comprises 12.3% of the nation's
population and 12.5% 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,
entertainment, real estate, and financial services. After experiencing strong
growth throughout much of the 1980s, from 1990-1993 the State suffered through a
severe recession, the worst since the 1930's, heavily influenced by large
cutbacks in defense/aerospace industries and military base closures and a major
drop in real estate construction. California's economy has been recovering and
growing steadily stronger since the start of 1994, to the point where the
State's economic growth is outpacing the rest of the nation. The unemployment
rate, while still higher than the national average, fell to an average of 5.9%
in 1998, compared to over 10% at the worst of the recession. 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 year, the increases in employment and
income may exceed those of the nation as a whole. The unsettled financial
situation occurring in certain Asian economies, and its spillover effect
elsewhere, may adversely affect the State's export-related industries and,
therefore, the State's rate of economic growth.
 
    The Governor signed the 1998-99 Budget Act on August 21, 1998. The 1998-99
Budget Act is based on projected General Fund revenues and transfers of $57.0
billion (after giving effect to various tax reductions enacted in 1997 and
1998), a 4.2% increase from the revised 1997-98 figures. Special Fund revenues
were estimated at $14.3 billion. The revenue projections were based on the
Governor's May Revision to the 1998-99 Budget and may be overstated in light of
the possible effect on California's economic growth of worsening economic
problems in various international markets.
 
    The Budget Act provides authority for expenditures of $57.3 billion from the
General Fund (a 7.3% increase from 1997-98), $14.7 billion from Special Funds,
and $3.4 billion from bond funds. The Budget Act projects a balance in the SFEU
at June 30, 1999 of $1.255 billion, a little more than 2% of General Fund
revenues. The Budget Act assumes the State will carry out its normal intra-year
cash flow borrowing in the amount of $1.7 billion of revenue anticipation notes
issued in October, 1998.
 
    The most significant feature of the 1998-99 budget was agreement on a total
of $1.4 billion of tax cuts. The central element is a bill which provides for a
phased-in reduction of the Vehicle License Fee (VLF). Since the VLF is currently
transferred to cities and counties, the bill provides for the General Fund to
replace the lost revenues. Starting on January 1, 1999, the VLF will be reduced
by 25%, at a cost to the General Fund of approximately $500 million in the
1998-99 Fiscal Year and about $1 billion annually thereafter.
 
                                       11

    The Governor's proposed budget for fiscal year 1999-2000 proposes total
State spending of $76.2 billion (excluding the expenditure of federal funds and
selected bond funds), which is up 4.1% from the 1998-1999 budget. This total
includes $60.5 billion in General Fund spending (a 3.8% increase) and $15.7
billion in special funds spending. The Governor's proposed budget anticipates a
$415 million reserve by the close of the fiscal year. The proposed budget
addresses an anticipated funding shortfall of $2.3 billion (which includes funds
to rebuild the reserve) through a combination of new state and federal
resources, the rescheduling of certain expenditures, under budgeting certain
expenditures, spending cutbacks, and savings assumptions.
 
    As of November 1, 1998, the State had over $18.6 billion aggregate amount of
its general obligation bonds outstanding. General obligation bond authorizations
in an aggregate amount of approximately $5.7 billion remained unissued as of
November 1, 1998. At the November 3, 1998 election voters approved a bond
measure totaling $9.2 billion for public school construction and renovation, and
for higher education facilities. The State also builds and acquires capital
facilities through the use of lease purchase borrowing. As of November 1, 1998,
the State had approximately $6.5 billion of outstanding Lease-Purchase Debt.
 
    In addition to the general obligation bonds, State agencies and authorities
had approximately $24.6 billion aggregate principal amount of revenue bonds and
notes outstanding as of September 30, 1998. Revenue bonds represent both
obligations payable from State revenue-producing enterprises and projects, which
are not payable from the General Fund, and conduit obligations payable only from
revenues paid by private users of facilities financed by such revenue bonds.
Such enterprises and projects include transportation projects, various public
works and exposition projects, educational facilities (including the California
State University and University of California systems), housing, health
facilities, and pollution control facilities.
 
    Because of the State of California's budget problems, the State's General
Obligation bonds were downgraded in July 1994 to A1 from Aa by Moody's, to A
from A+ by S&P, and to A from AA by Fitch. Moody's, Fitch and S&P expressed
uncertainty in the State's ability to balance its budget by 1996. However, in
1996, citing California's improving economy and budget situation, both Fitch and
S&P raised their ratings from A to A+. In October, 1997, Fitch raised its rating
from A+ to AA- referring to the State's fundamental strengths, the extent of its
economic recovery and the return of financial stability. In October 1998,
Moody's raised its rating from A1 to Aa3 citing the State's continuing economic
recovery and a number of actions taken to improve the State's credit condition,
including the rebuilding of cash and budget reserves.
 
    The State is a party to numerous legal proceedings, many of which normally
occur in governmental operations and which, if decided against the State, might
require the State to make significant future expenditures or impair future
revenue sources.
 
    YEAR 2000.  In October 1997 the Governor issued Executive Order W-163-97
stating that Year 2000 solutions would be a State priority and requiring each
agency of the State, no later than December 31, 1998, to address Year 2000
problems in their essential systems and protect those systems from corruption by
non-compliant systems, in accordance with the Department of Information
Technology's California 2000 Program. There can be no assurance that steps being
taken by state or local government agencies with respect to the Year 2000
problem will be sufficient to avoid any adverse impact upon the budgets or
operations of those agencies.
 
    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%. In December, 1997, Moody's raised its ratings on $325
million of Orange County pension obligation bonds to Baa3 from Ba. In February
1998, Fitch assigned outstanding Orange County pension obligation bonds a BBB
rating.
 
                                       12
<PAGE>
    Los Angeles County, the nation's largest county, has also experienced
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, and among
other things, severe operating deficits for the county's health care system. In
addition, the county was affected by an ongoing loss of revenue caused by state
property tax shift initiatives in 1993 through 1995. In April 1998, the Los
Angeles County Chief Administrative Officer proposed an approximately $13.2
billion 1998-99 budget, which would be 5.3% larger than the 1997-98 budget, and
which would not require cuts in services and jobs to close a projected deficit.
In June 1998, the Los Angeles County Board of Supervisors approved an
approximately $13.6 billion 1998-99 budget, reserving the right to make further
changes to reflect revenue allocation decisions in the final State budget. In
December 1998, Moody's raised the ratings on the County's general obligation
bonds to A1 from A2. The City of Los Angeles is the largest city in the county
and its general obligation bonds are rated AA by S&P and Aa by Moody's.
 
    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.
 
C. FUND POLICIES/INVESTMENT RESTRICTIONS
 
    The investment objective, policies and restrictions listed below have been
adopted by the Fund as fundamental policies. Under the Investment Company Act of
1940 (the "Investment Company Act"), a fundamental policy may not be changed
without the vote of a majority of the outstanding voting securities of the Fund.
The Investment Company Act defines a majority as the lesser of (a) 67% or more
of the shares present at a meeting of shareholders, if the holders of 50% of the
outstanding shares of the Fund are present or represented by proxy; or (b) more
than 50% of the outstanding shares of the Fund.
 
    In addition, for purposes of the following restrictions: (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
guarantee of a security 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 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 will:
 
         1.  Seek to provide a high level of current income which is exempt from
    both federal and California income tax, consistent with the preservation of
    Capital.
 
    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 are
    in the securities of any one 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 (industrial development and
    pollution control bonds are grouped into industries based upon the business
    in which the issuers of such obligations are engaged). This restriction does
    not apply to obligations issued or guaranteed by the United States
    Government, its agencies or instrumentalities or to municipal obligations,
    including those issued by the State of California or its political
    subdivisions.
 
         4.  Invest in common stock.
 
                                       13
<PAGE>
         5.  Write, purchase or sell puts, calls, or combinations thereof,
    except for options on futures contracts or options on debt securities.
 
         6.  Invest in securities of any issuer, if, to the knowledge of the
    Fund, any officer or trustee of the Fund or of the Investment Manager owns
    more than 1/2 of 1% of the outstanding securities of the issuer, and the
    officers and trustees who own more than 1/2 of 1% own in the aggregate more
    than 5% of the outstanding securities of the issuer.
 
         7.  Purchase or sell real estate or interests therein, although it may
    purchase securities secured by real estate or interests therein.
 
         8.  Purchase or sell commodities except that the Fund may purchase
    financial futures contracts and related options.
 
         9.  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).
 
        10.  Pledge its assets or assign or otherwise encumber them except to
    secure permitted borrowing. However, 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 11.
 
        11.  Issue senior securities as defined in the Investment Company Act,
    except insofar as the Fund may be deemed to have issued a senior security by

III. MANAGEMENT OF THE FUND
- --------------------------------------------------------------------------------
 
A. BOARD OF TRUSTEES
 
    The Board of Trustees of the Fund oversees the management of the Fund but
does not itself manage the Fund. The Trustees review various services provided
by or under the direction of the Investment Manager to ensure that the Fund's
general investment policies and programs are properly carried out. The Trustees
also conduct their review to ensure that administrative services are provided to
the Fund in a satisfactory manner.
 
                                       14
<PAGE>
    Under state law, the duties of the Trustees are generally characterized as a
duty of loyalty and a duty of care. The duty of loyalty requires a Trustee to
exercise his or her powers in the interest of the Fund and not the Trustee's own
interest or the interest of another person or organization. A Trustee satisfies
his or her duty of care by acting in good faith with the care of an ordinarily
prudent person and in a manner the Trustee reasonably believes to be in the best
interest of the Fund and its shareholders.
 
B. MANAGEMENT INFORMATION
 
    TRUSTEES AND OFFICERS.  The Board of the Fund consists of nine (9) Trustees.
These same individuals also serve as directors or trustees for all of the Morgan
Stanley Dean Witter Funds. Seven Trustees (77% of the total number) have no
affiliation or business connection with the Investment Manager or any of its
affiliated persons and do not own any stock or other securities issued by the
Investment Manager's parent company, MSDW. These are the "non-interested" or
"independent" Trustees. The other two Trustees (the "management Trustees") are
affiliated with the Investment Manager. All of the Independent Trustees also
serve as Independent Trustees of "Discover Brokerage Index Series," a mutual
fund for which the Investment Manager is the investment advisor. Four of the
seven Independent Trustees are also Independent Trustees of certain other mutual
funds, referred to as the "TCW/DW Funds," for which MSDW Services Company is the
manager and TCW Funds Management, Inc. is the investment advisor.
 
    The Trustees and executive officers of the Fund, their principal business
occupations during the last five years and their affiliations, if any, with the
Investment Manager, and with the 84 Morgan Stanley Dean Witter Funds, the 11
TCW/DW Funds and Discover Brokerage Index Series, are shown below.

    INDEPENDENT TRUSTEES AND THE COMMITTEES.  Law and regulation establish both
general guidelines and specific duties for the Independent Trustees. The Morgan
Stanley 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 Independent Trustees
serve as members of the Audit Committee. In addition, three of the Trustees,
including two Independent Trustees, serve as members of the Derivatives
Committee and the Insurance Committee.
 
    The Independent Trustees are 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 Morgan Stanley Dean Witter Funds have a Rule 12b-1
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 the 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.
 
                                       18
<PAGE>
    The Board of each Fund has a Derivatives Committee to approve parameters for
and monitor the activities of the Fund with respect to derivative investments,
if any, made by the Fund.
 
    Finally, the Board of each Fund has formed an Insurance Committee to review
and monitor the insurance coverage maintained by the Fund.
 
    ADVANTAGES OF HAVING SAME INDIVIDUALS AS INDEPENDENT TRUSTEES FOR ALL MORGAN
STANLEY DEAN WITTER FUNDS.  The Independent Trustees and the Funds' management
believe that having the same Independent Trustees for each of the Morgan Stanley
Dean Witter Funds avoids the duplication of effort that would arise from having
different groups of individuals serving as Independent Trustees for each of the
Funds or even of sub-groups of Funds. They believe that having the same
individuals serve as Independent Trustees of all the Funds tends to increase
their knowledge and expertise regarding matters which affect the Fund complex
generally and enhances their ability to negotiate on behalf of each Fund with
the Fund's service providers. This arrangement also precludes the possibility of
separate groups of Independent Trustees arriving at conflicting decisions
regarding operations and management of the Funds and avoids the cost and
confusion that would likely ensue. Finally, having the same Independent Trustees
serve on all Fund Boards enhances the ability of each Fund to obtain, at modest
cost to each separate Fund, the services of Independent Trustees, of the
caliber, experience and business acumen of the individuals who serve as
Independent Trustees of the Morgan Stanley Dean Witter Funds.
 
    TRUSTEE AND OFFICER INDEMNIFICATION.  The Fund's 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, 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.
 
C. COMPENSATION
 
    The Fund pays each Independent Trustee an annual fee of $800 plus a per
meeting fee of $50 for meetings of the Board of Trustees, the Independent
Trustees or Committees of the Board of Trustees attended by the Trustee (the
Fund pays the Chairman of the Audit Committee an additional annual fee of $750).
If a Board meeting and a meeting of the Independent Trustees or a Committee
meeting, or a meeting of the Independent Trustees and/or more than one Committee
meeting, take place on a single day, the Trustees are paid a single meeting fee
by the Fund. 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 expenses
reimbursed from the Fund for their services as Trustee. Mr. Haire currently
serves as Chairman of the Audit Committee. Prior to June 1, 1998, Mr. Haire also
served as Chairman of the Independent Trustees for which services the Fund paid
him an additional annual fee of $1,200. Effective May 1, 1999, Dr. Johnson
serves as Chairman of the Audit Committee.

December 31, 1998. Effective May 1, 1999, Dr. Johnson serves as Chairman of the
Audit Committee of each Morgan Stanley Dean Witter Fund and each TCW/DW Fund.
With respect to Messrs. Johnson, Nugent and Schroeder, the TCW/DW Funds are
included solely because of a limited exchange privilege between those Funds and

the Fund's Independent Trustees by Discover Brokerage Index Series for the
calendar year ended December 31, 1998.

    As of the date of this STATEMENT OF ADDITIONAL INFORMATION, 55 of the Morgan
Stanley 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 Morgan Stanley 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 30.22% of his or her Eligible Compensation plus
0.5036667% 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 60.44% after ten years of
 
                                       20
<PAGE>
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 year ended December 31, 1998 and
by the 55 Morgan Stanley Dean Witter Funds (including the Fund) for the year
ended December 31, 1998, and the estimated retirement benefits for the
Independent Trustees, to commence upon their retirement, from the Fund as of
December 31, 1998 and from the 55 Morgan Stanley Dean Witter Funds as of
December 31, 1998.

    periodic payment of benefits will be equal to a lower percentage of the
    periodic amount when both spouses were alive. The amount estimated to be
    payable under this method, through the remainder of the later of the lives
    of the Eligible Trustee and spouse, will be the actuarial equivalent of the

V. INVESTMENT MANAGEMENT AND OTHER SERVICES
- --------------------------------------------------------------------------------
 
A. INVESTMENT MANAGER
 
    The Investment Manager to the Fund is Morgan Stanley Dean Witter Advisors
Inc., a Delaware corporation, whose address is Two World Trade Center, New York,
New York 10048. The Investment Manager is a wholly-owned subsidiary of MSDW, a
Delaware corporation. MSDW is a preeminent global financial services firm that
maintains leading market positions in each of its three primary businesses:
securities, asset management and credit services.
 
    Pursuant to an Investment Management Agreement (the "Management Agreement")
with the Investment Manager, the Fund has retained the Investment Manager to
provide administrative services and manage the investment of the Fund's assets,
including the placing of orders for the purchase and sale of portfolio
securities. The Fund pays the Investment Manager monthly compensation calculated
daily by applying the following annual rates to the net assets of the Fund
determined as of the close of each business day: 0.55% to the portion of daily
net assets not exceeding $500 million; 0.525% to the
 
                                       21
<PAGE>
portion of daily net assets exceeding $500 million but not exceeding $750
million; 0.50% to the portion of daily net assets exceeding $750 million but not
exceeding $1 billion; and 0.475% of the portion of the daily net assets
exceeding $1 billion. The management fee is allocated among the Classes pro rata
based on the net assets of the Fund attributable to each Class. For the fiscal
years ended December 31, 1996, 1997 and 1998, the Investment Manager accrued
total compensation under the Management Agreement in the amounts of $5,313,150,
$4,966,928 and $4,871,646, respectively.
 
    The Investment Manager has retained its wholly-owned subsidiary, MSDW
Services Company, to perform administrative services for the Fund.
 
B. PRINCIPAL UNDERWRITER
 
    The Fund's principal underwriter is the Distributor (which has the same
address as the Investment Manager). In this capacity, the Fund's shares are
distributed by the Distributor. The Distributor has entered into a selected
dealer agreement with Dean Witter Reynolds, which through its own sales
organization sells shares of the Fund. In addition, the Distributor may enter
into similar agreements with other selected broker-dealers. The Distributor, a
Delaware corporation, is a wholly-owned subsidiary of MSDW.
 
    The Distributor bears all expenses it may incur in providing services under
the Distribution Agreement. These expenses include the payment of commissions
for sales of the Fund's shares and incentive compensation to Financial Advisors.
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 and state 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. 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 any losses sustained by the
Fund or its shareholders.
 
C. SERVICES PROVIDED BY THE INVESTMENT MANAGER AND FUND EXPENSES PAID BY THIRD
PARTIES
 
    The Investment Manager manages 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 the 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.
 
    Under the terms of the Management 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, the 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.
 
    Expenses not expressly assumed by the Investment Manager under the
Management Agreement or by the Distributor, will be paid by the Fund. These
expenses will be allocated among the four Classes of shares pro rata based on
the net assets of the Fund attributable to each Class, except as described
 
                                       22
<PAGE>
below. Such expenses include, but are not limited to: expenses of the Plan of
Distribution pursuant to Rule 12b-1; charges and expenses of any registrar,
custodian, stock transfer and dividend disbursing agent; brokerage commissions;
taxes; engraving and printing share certificates; registration costs of the Fund
and its shares under federal and state securities laws; the cost and expense of
printing, including typesetting, and distributing prospectuses 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 employees of the Investment
Manager); fees and expenses of the Fund's 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.
 
    The Management 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 Management Agreement will remain in effect from year to year, provided
continuance of the Management Agreement is approved at least annually by the
vote of the holders of a majority, as defined in the Investment Company Act, of
the outstanding shares of the Fund, or by the Trustees; provided that in either
event such continuance is approved annually by the vote of a majority of the
Trustees.
 
D. DEALER REALLOWANCES
 
    Upon notice to selected broker-dealers, the Distributor may reallow up to
the full applicable front-end sales charge 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.
 
E. RULE 12b-1 PLAN
 
    The Fund has adopted a Plan of Distribution pursuant to Rule 12b-1 under the
Investment Company 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 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 contingent 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
("FSCs") and of contingent deferred sales charges ("CDSCs") imposed on certain
redemptions of shares, which are separate and apart from payments made pursuant
to the Plan. The Distributor has informed the Fund that it and/or
 
                                       23
<PAGE>
Dean Witter Reynolds received the proceeds of CDSCs and FSCs, for the last three
fiscal years ended December 31, in approximate amounts as provided in the table
below (the Distributor did not retain any of these amounts).

(4) FSCs apply to Class A only.
 
(5) This Class commenced operations on July 28, 1997.
 
    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 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 Rules of the Association.
 
    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. Class B shares of the Fund accrued amounts
payable to the Distributor under the Plan, during the fiscal year ended December
31, 1998, of $6,763,732. 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. The Distributor rebated a total of
3,465,883 back to the Fund. Therefore, the total amount paid by the Distributor
was $3,297,849, which amount is equal to 0.37% of the Fund's average daily net
assets for the year. For the fiscal year ended December 31, 1998, Class A and
Class C shares of the Fund accrued payments under the Plan amounting to $6,337
and $53,763, respectively, which amounts are equal to 0.25% and 0.75% of the
average daily net assets of Class A and Class C, respectively, for the fiscal
year.
 
    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, each with a different distribution arrangement.
 
    With respect to Class A shares, Dean Witter Reynolds compensates its
Financial Advisors by paying them, from proceeds of the FSC, 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 Financial Advisors 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 Financial Advisors by paying them,
from its own funds, a gross sales credit of 1.0% of the amount sold.
 
    With respect to Class B shares, Dean Witter Reynolds compensates its
Financial Advisors 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, Dean Witter Reynolds compensates its
Financial Advisors 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 up to 0.75% of the current
value of the respective accounts for which they are the Financial Advisors of
record.
 
                                       24
<PAGE>
    With respect to Class D shares other than shares held by participants in the
Investment Manager's mutual fund asset allocation program, the Investment
Manager compensates Dean Witter Reynolds's Financial Advisors 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 Dean Witter
Reynolds's Financial Advisors by paying them, from its own funds, an annual
residual commission, currently up to 0.10% of the current value of the
respective accounts for which they are the Financial Advisors of record (not
including accounts of participants in the Investment Manager's mutual fund asset
allocation program).
 
    The gross sales credit is a charge which reflects commissions paid by Dean
Witter Reynolds to its Financial Advisors and Dean Witter Reynolds's
Fund-associated distribution-related expenses, including sales compensation, and
overhead and other branch office distribution-related expenses including (a) the
expenses of operating Dean Witter Reynolds's branch offices in connection with
the sale of Fund shares, including lease costs, the salaries and employee
benefits of operations and sales support personnel, utility costs,
communications costs and the costs of stationery and supplies; (b) the costs of
client sales seminars; (c) travel expenses of mutual fund sales coordinators to
promote the sale of Fund shares; and (d) other expenses relating to branch
promotion of Fund sales.
 
    The distribution fee that the Distributor receives from the Fund under the
Plan, in effect, offsets distribution expenses incurred under the Plan on behalf
of the Fund and, in the case of Class B shares, opportunity costs, such as the
gross sales credit and an assumed interest charge thereon ("carrying charge").
In the Distributor's reporting of the distribution expenses to the Fund, in the
case of Class B shares, such assumed interest (computed at the "broker's call
rate") has been calculated on the gross credit as it is reduced by amounts
received by the Distributor under the Plan and any contingent deferred sales
charges received by the Distributor upon redemption of shares of the Fund. No
other interest charge is included as a distribution expense in the Distributor's
calculation of its distribution costs for this purpose. The broker's call rate
is the interest rate charged to securities brokers on loans secured by
exchange-listed securities.
 
    The Fund is authorized to reimburse expenses incurred or to be incurred in
promoting the distribution of the Fund's Class A and Class C shares and in
servicing shareholder accounts. Reimbursement will be made through payments at
the end of each month. The amount of each monthly payment may in no event exceed
an amount equal to a payment at the annual rate of 0.25%, in the case of Class
A, and 0.75%, 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 Financial Advisors and other authorized financial
representatives, such amounts shall be determined at the beginning of each
calendar quarter by the Trustees, including, a majority of the Independent
Trustees. Expenses representing the service fee (for Class A) or a gross sales
credit or a residual to Financial Advisors and other authorized financial
representatives (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.
 
    Each Class paid 100% of the amounts accrued under the Plan with respect to
that Class for the fiscal year ended December 31, 1998 to the Distributor. The
Distributor and Dean Witter Reynolds estimate that they have spent, pursuant to
the Plan, $85,599,795 on behalf of Class B since the inception of the Plan. It
is estimated that this amount was spent in approximately the following ways: (i)
4.43%
 
                                       25
<PAGE>
($3,792,254)--advertising and promotional expenses; (ii) 0.33% ($278,382
)--printing of prospectuses for distribution to other than current shareholders;
and (iii) 95.24% ($81,529,159)--other expenses, including the gross sales credit
and the carrying charge, of which 7.51% ($6,119,779) represents carrying
charges, 37.83% ($30,842,436) represents commission credits to Dean Witter
Reynolds branch offices and other authorized financial representatives for
payments of commissions to Financial Advisors and other authorized financial
representatives, and 54.66% ($44,566,944) represents overhead and other branch
office distribution-related expenses. The amounts accrued by Class A and Class C
for distribution during the fiscal year ended December 31, 1998 were for
expenses which relate to compensation of sales personnel and associated overhead
expenses.
 
    In the case of Class B 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 CDSCs
paid by investors upon redemption of 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 in
the case of Class B shares the excess distribution expenses, including the
carrying charge designed to approximate the opportunity costs incurred by Dean
Witter Reynolds 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, totaled ($230,396) as of December 31, 1998 (the end of
the Fund's fiscal year), which was equal to -0.03% of the net assets of Class B
on such date. Because there is no requirement under the Plan that the
Distributor be reimbursed for all distribution expenses 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 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 Morgan Stanley Dean Witter Financial Advisors
and other authorized financial representatives at the time of sale may be
reimbursed in the subsequent calendar year. The Distributor has advised the Fund
that unreimbursed expenses representing a gross sales commission credited to
Morgan Stanley Dean Witter Financial Advisors and other authorized financial
representatives at the time of sale totaled $20,536 in the case of Class C at
December 31, 1998 (the end of the calendar year), which amount was equal to
0.21% of the net assets of Class C on such date, and that there were no such
expenses that may be reimbursed in the subsequent year in the case of Class A on
such date. 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.
 
    No interested person of the Fund nor any Independent Trustee has any direct
financial interest in the operation of the Plan except to the extent that the
Distributor, the Investment Manager, Dean Witter Reynolds, MSDW Services Company
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.
 
    On an annual basis, the Trustees, including a majority of the Independent
Trustees, consider whether the Plan should be continued. Prior to approving the
last 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, including that: (a) the Plan is essential in order to give Fund
 
                                       26
<PAGE>
investors a choice of alternatives for payment of distribution and service
charges and to enable the Fund to continue to grow and avoid a pattern of net
redemptions which, in turn, are essential for effective investment management;
and (b) without the compensation to individual brokers and the reimbursement of
distribution and account maintenance expenses of Dean Witter Reynolds's branch
offices made possible by the 12b-1 fees, Dean Witter Reynolds could not
establish and maintain an effective system for distribution, servicing of Fund
shareholders and maintenance of shareholder accounts; 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, including each of the
Independent 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 Trustees or by a vote of a majority of the
outstanding voting securities of the Fund (as defined in the Investment Company
Act) on not more than thirty days' written notice to any other party to the
Plan. So long as the Plan is in effect, the election and nomination of
Independent Trustees shall be committed to the discretion of the Independent
Trustees.

VI. BROKERAGE ALLOCATION AND OTHER PRACTICES
- --------------------------------------------------------------------------------
 
A. BROKERAGE TRANSACTIONS
 
    Subject to the general supervision of the Trustees, the Investment Manager
is responsible for decisions to buy and sell securities for the Fund, the
selection of brokers and dealers to effect the transactions, and the negotiation
of brokerage commissions, if any. Purchases and sales of securities on a stock
exchange are effected through brokers who charge a commission for their
services. In the over-the-counter market, securities are generally traded on a
"net" basis with dealers acting as principal for their own accounts without a
stated commission, although the price of the security usually includes a
 
                                       27
<PAGE>
profit to the dealer. 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.
Options and futures transactions will usually be effected through a broker and a
commission will be charged. On occasion, the Fund may also purchase certain
money market instruments directly from an issuer, in which case no commissions
or discounts are paid.
 
    For the fiscal years ended December 31, 1996, 1997 and 1998, the Fund did
not pay any brokerage commissions.
 
B. COMMISSIONS
 
    Pursuant to an order of the SEC, the Fund may effect principal transactions
in certain money market instruments with Dean Witter Reynolds. The Fund will
limit its transactions with Dean Witter Reynolds to U.S. Government and
government agency securities, bank money instruments (i.e., certificates of
deposit and bankers' acceptances) and commercial paper. The transactions will be
effected with Dean Witter Reynolds only when the price available from Dean
Witter Reynolds is better than that available from other dealers.
 
    During the fiscal years ended December 31, 1996, 1997 and 1998, the Fund did
not effect any principal transactions with Dean Witter Reynolds.
 
    Consistent with the policy described above, brokerage transactions in
securities listed on exchanges or admitted to unlisted trading privileges may be
effected through Dean Witter Reynolds, Morgan Stanley & Co. and other affiliated
brokers and dealers. In order for an affiliated broker or dealer to effect any
portfolio transactions on an exchange for the Fund, the commissions, fees or
other remuneration received by the affiliated broker or dealer must be
reasonable and fair compared to the commissions, fees or other remuneration paid
to other brokers in connection with comparable transactions involving similar
securities being purchased or sold on an exchange during a comparable period of
time. This standard would allow the affiliated broker or dealer to receive no
more than the remuneration which would be expected to be received by an
unaffiliated broker in a commensurate arm's-length transaction. Furthermore, the
Trustees, including the Independent 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 Fund does not reduce the management fee it pays to the Investment
Manager by any amount of the brokerage commissions it may pay to an affiliated
broker or dealer.
 
C. BROKERAGE SELECTION
 
    The policy of the Fund regarding purchases and sales of securities for its
portfolio is that primary consideration will be given to obtaining the most
favorable prices and efficient executions of transactions. Consistent with this
policy, when securities transactions are effected on a stock exchange, the
Fund's policy is to pay commissions which are considered fair and reasonable
without necessarily determining that the lowest possible commissions are paid in
all circumstances. The Fund believes that a requirement always to seek the
lowest possible commission cost could impede effective portfolio management and
preclude the Fund and the Investment Manager from obtaining a high quality of
brokerage and research services. In seeking to determine the reasonableness of
brokerage commissions paid in any transaction, the Investment Manager relies
upon its experience and knowledge regarding commissions generally charged by
various brokers and on its judgment in evaluating the brokerage and research
services received from the broker effecting the transaction. These
determinations are necessarily subjective and imprecise, as in most cases an
exact dollar value for those services is not ascertainable.
 
    In seeking to implement the Fund's policies, the Investment Manager effects
transactions with those brokers and dealers who the Investment Manager believes
provide the most favorable prices and are capable of providing efficient
executions. If the Investment Manager believes the prices and executions are
obtainable from more than one broker or dealer, it may give consideration to
placing portfolio transactions with those brokers and dealers who also furnish
research and other services to the Fund or the Investment Manager. The 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
 
                                       28
<PAGE>
information or opinions pertaining to investment; wire services; and appraisals
or evaluations of portfolio securities. The information and services received by
the Investment Manager from brokers and dealers may be of benefit to the
Investment Manager in the management of accounts of some of its other clients
and may not in all cases benefit the Fund directly.
 
    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 advisor to others. It is the practice of the Investment
Manager to cause purchase and sale transactions to be allocated among the Fund
and others whose assets it manages in such manner as it deems equitable. In
making such allocations among the Fund and other client accounts, various
factors may be considered, including the respective investment objectives, the
relative size of portfolio holdings of the same or comparable securities, the
availability of cash for investment, the size of investment commitments
generally held and the opinions of the persons responsible for managing the
portfolios of the Fund and other client accounts. In the case of certain initial
and secondary public offerings, the Investment Manager utilizes a pro rata
allocation process based on the size of the Morgan Stanley Dean Witter Funds
involved and the number of shares available from the public offering.
 
D. DIRECTED BROKERAGE
 
    During the fiscal year ended December 31, 1998, the Fund did not pay any
brokerage commissions in connection with transactions to brokers because of
research services provided.
 
E. REGULAR BROKER-DEALERS
 
    During the fiscal year ended December 31, 1998, the Fund did not purchase
securities issued by brokers or dealers that were among the ten brokers or the
ten dealers which executed transactions for or with the Fund in the largest
dollar amounts during the year. At December 31, 1998, the Fund did not purchase
securities issued by any of such issuers.
 
VII. CAPITAL STOCK AND OTHER SECURITIES
- --------------------------------------------------------------------------------
 
    The shareholders of the Fund are entitled to a full vote for each full share
of beneficial interest held. The Fund is authorized to issue an unlimited number
of shares of beneficial interest. 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, Class A, Class B
and Class C bear expenses related to the distribution of their respective
shares.
 
    The Fund's 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 presently authorized any such
additional series or Classes of shares other than as set forth in the
PROSPECTUS.
 
    The Fund is not required to hold annual meetings of shareholders and in
ordinary circumstances the Fund does not intend to hold such meetings. The
Trustees may call special meetings of shareholders for action by shareholder
vote as may be required by the Investment Company Act or the Declaration of
Trust. Under certain circumstances, the Trustees may be removed by action of the
Trustees or by the shareholders.
 
    Under Massachusetts law, shareholders of a business trust may, under certain
limited circumstances, be held personally liable as partners for the obligations
of the Fund. However, the Declaration of Trust contains an express disclaimer of
shareholder liability for acts or obligations of the Fund, requires that notice
of such Fund obligations include such disclaimer, and provides for
indemnification out of the Fund's property for any shareholder held personally
liable for the obligations of the Fund. Thus, the risk of a shareholder
incurring financial loss on account of shareholder liability is limited to
circumstances in which the Fund itself would be unable to meet its obligations.
Given the above limitations on shareholder
 
                                       29
<PAGE>
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 thus,
in the opinion of Massachusetts counsel to the Fund, the risk to Fund
shareholders of personal liability is remote.
 
    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. The Trustees
themselves have the power to alter the number and the terms of office of the
Trustees (as provided for in the Declaration of Trust), and they may at any time
lengthen or shorten 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.
 
VIII. PURCHASE, REDEMPTION AND PRICING OF SHARES
- --------------------------------------------------------------------------------
 
A. PURCHASE OF SHARES
 
    Information concerning how Fund shares are offered to the public (and how
they are redeemed and exchanged) is provided in the Fund's PROSPECTUS.
 
    TRANSFER AGENT AS AGENT.  With respect to the redemption or repurchase of
Fund shares, the application of proceeds to the purchase of new shares in the
Fund or any other Morgan Stanley Dean Witter Funds and the general
administration of the exchange privilege, the Transfer Agent acts as agent for
the Distributor and for the shareholder's authorized 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 authorized broker-dealer.
 
    The Distributor and any authorized broker-dealer have 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 Morgan
Stanley Dean Witter Fund and the general administration of the exchange
privilege. No commission or discounts will be paid to the Distributor or any
authorized broker-dealer for any transaction pursuant to the exchange privilege.
 
    TRANSFERS OF SHARES.  In the event a shareholder requests a transfer of Fund
shares to a new registration, the shares will be transferred without sales
charge at the time of transfer. With regard to the status of shares which are
either subject to the CDSC or free of such charge (and with regard to the length
of time shares subject to the charge have been held), any transfer involving
less than all of the shares in an account will be made on a pro rata basis (that
is, by transferring shares in the same proportion that the transferred shares
bear to the total shares in the account immediately prior to the transfer). The
transferred shares will continue to be subject to any applicable CDSC as if they
had not been so transferred.
 
B. OFFERING PRICE
 
    The Fund's Class B, Class C and Class D shares are offered at net asset
value per share and the Class A shares are offered at net asset value per share
plus any applicable FSC which is distributed among the Fund's Distributor, Dean
Witter Reynolds and other authorized dealers as described in Section "V.
Investment Management and Other Services--E Rule 12b-1 Plan."
 
    The price of the Fund, called "net asset value," is based on the value of
the Fund's portfolio securities.
 
    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 Trustees. The pricing service has informed the Fund that in
valuing the portfolio securities for the Fund 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 portfolio securities for the
Fund 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
 
                                       30
<PAGE>
of issue, call provisions, trading characteristics and other features deemed to
be relevant. The Trustees believe 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 Trustees the use of other pricing services or
discontinuance of the use of any pricing service in whole or part. The Trustees
may determine to approve such recommendation or take other provisions for
pricing of the portfolio securities for the Fund.
 
    Short-term taxable debt securities with remaining maturities of 60 days or
less at time of purchase are valued at amortized cost, unless the Trustees
determine such does not reflect the securities' market value, in which case
these securities will be valued at their fair value as determined by the
Trustees. Other taxable short-term debt securities with maturities of more than
60 days will be valued on a mark to market basis until such time as they reach a
maturity of 60 days, whereupon they will be valued at amortized cost using their
value on the 61st day unless the 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 their latest
bid and asked price. Futures are valued at the latest sale price on the
commodities exchange on which they trade unless the Trustees determines that
such price does not reflect their fair value, in which case they will be valued
at their fair market value as determined by the Trustees. All other securities
and other assets are valued at their fair value as determined in good faith
under procedures established by and under the supervision of the Trustees.
 
IX. TAXATION OF THE FUND AND SHAREHOLDERS
- --------------------------------------------------------------------------------
 
    The Fund generally will make three basic types of distributions: tax exempt
dividends, ordinary dividends and long-term capital gain distributions. These
types of distributions are reported differently on a shareholder's income tax
return and they are also subject to different rates of tax. The tax treatment of
the investment activities of the Fund will affect the amount and timing and
character of the distributions made by the Fund. Shareholders are urged to
consult their own tax professionals regarding specific questions as to federal,
state or local taxes.
 
    INVESTMENT COMPANY TAXATION.  The Fund intends to remain qualified as a
regulated investment company under Subchapter M of the Internal Revenue Code of
1986. As such, the Fund will not be subject to federal income tax on its net
investment income and capital gains, if any, to the extent that it distributes
such income and capital gains to its shareholders.
 
    All or a portion of any gain from tax-exempt obligations purchased at a
market discount may be treated as ordinary income rather than capital gain.
 
    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. 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 that event, the Fund
would re-evaluate its investment objective and policies.
 
    TAXATION OF DIVIDENDS AND DISTRIBUTIONS.  The Fund intends to qualify to pay
"exempt-interest dividends" to its shareholders by maintaining, as of the close
of each of its taxable years, at least 50% of the value of its assets in
tax-exempt securities. An exempt-interest dividend is that part of the 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. 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.
 
                                       31
<PAGE>
    The Fund intends to invest a portion of its assets in certain "private
activity bonds". As a result, 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. 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.
 
    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 capital gains,
regardless of how long the shareholder has held the Fund shares and regardless
of whether the distribution is received in additional shares or in cash. Since
the income of the Fund is expected to be derived entirely from interest rather
than dividends, it is anticipated that no portion of such dividend distributions
will be eligible for the federal dividends received deduction available to
corporations.
 
    Shareholders are generally taxed on any ordinary dividend or capital gain
distributions from the Fund in the year they are actually distributed. However,
if any such dividends or distributions are declared in October, November or
December and paid in January then such amounts will be treated for tax purposes
as received by the shareholders on December 31, to shareholders of record of
such month.
 
    Shareholders who are not citizens or residents of the United States and
certain foreign entities may be subject to withholding of United States tax on
distributions made by the Fund of any taxable interest income and short term
capital gains.
 
    After the end of each calendar year, shareholders will be sent full
information on their dividends and capital gain distributions for tax purposes,
including the portion taxable as ordinary income, the portion taxable as
long-term capital gains and the percentage of any distributions which constitute
an item of tax preference for purposes of the alternative minimum tax.
 
    PURCHASES AND REDEMPTIONS AND EXCHANGES OF FUND SHARES.  Any dividend or
capital gains distribution received by a shareholder from the Fund will have the
effect of reducing the net asset value of the shareholder's stock in the Fund by
the exact amount of the dividend or capital gains distribution. Furthermore,
capital gains distributions and some portion of the dividends may be subject to
federal income taxes. If the net asset value of the shares should be reduced
below a shareholder's cost as a result of the payment of dividends or the
distribution of realized long-term capital gains, such payment or distribution
would be in part a return of the shareholder's investment but nonetheless would
be taxable to the shareholder. Therefore, an investor should consider the tax
implications of purchasing shares of the Fund immediately prior to a
distribution record date.
 
    In general, a sale of shares results in capital gain or loss, and for
individual shareholders, is taxable at a federal rate dependent upon the length
of time the shares were held. A redemption of a shareholder's Fund shares is
normally treated as a sale for tax purposes. Shares of the Fund held for a
period of one year or less will, for tax purposes, generally result in
short-term gains or losses and those held for more than one year generally
result in long-term gain or loss. Any loss realized by shareholders upon a
redemption of shares within six months of the date of their purchase will be
treated as a long-term capital loss to the extent of any distributions of net
long-term capital gains with respect to such shares during the six-month period.
 
    Gain or loss on the sale or redemption of shares in the Fund is measured by
the difference between the amount received and the tax basis of the shares.
Shareholders should keep records of investments made (including shares acquired
through reinvestment of dividends and distributions) so they can compute the tax
basis of their shares. Under certain circumstances a shareholder may compute and
use an average cost basis in determining the gain or loss on the sale or
redemption of shares.
 
                                       32
<PAGE>
    Exchanges of shares in the Fund for shares of other Morgan Stanley Dean
Witter Funds, are also subject to similar tax treatment. Such an exchange is
treated for tax purposes as a sale of the original shares in the Fund, followed
by the purchase of shares in the Fund.
 
    If a shareholder realizes a loss on the redemption or exchange of a shares
in the Fund and reinvests in shares of the Fund within 30 days before or after
the redemption or exchange, the transactions may be subject to the "wash sale"
rules, resulting in a postponement of the recognition of such loss for tax
purposes.
 
    Interest on indebtedness incurred by shareholders to purchase or carry
shares of the Fund is not deductible. 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.
 
    THE STATE OF CALIFORNIA--SPECIAL TAX CONSIDERATIONS.  In any year in which
the Fund qualifies as a regulated investment company under the Internal Revenue
Code as in effect on January 1, 1998, 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 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 on 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 an 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 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 shares of the Fund and regardless
of whether the distribution is received in additional shares or in cash. The
maximum federal capital gains rate for individuals is 20% with respect to
capital assets held more than 12 months. The maximum capital gains rate for
corporate shareholders is the same as the maximum tax rate for ordinary income.
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.
 
    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 federal or state personal income tax purposes. In addition, as a result of
 
                                       33
<PAGE>
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 redemption 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 long-term capital loss
to the extent of such long-term capital gains distribution. Finally, any loss
realized upon the redemption of shares within 30 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 excludable from taxable income in determining the California
corporate franchise tax for corporate shareholders. Such distributions may also
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.
 
X. UNDERWRITERS
- --------------------------------------------------------------------------------
 
    The Fund's shares are offered to the public on a continuous basis. The
Distributor, as the principal underwriter of the shares, has certain obligations
under the Distribution Agreement concerning the distribution of the shares.
These obligations and the compensation the Distributor receives are described
above in the sections titled "Principal Underwriter" and "Rule 12b-1 Plans."
 
XI. CALCULATION OF PERFORMANCE DATA
- --------------------------------------------------------------------------------
 
    From time to time, the Fund may quote its "yield" and/or "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. The yields for the 30-day
period ended December 31, 1998, calculated pursuant to the formula described
above, were 3.77%, 3.43%, 3.43% and 4.20% for Class A, Class B, Class C and
Class D, respectively.
 
    These figures are computed separately for Class A, Class B, Class C and
Class D shares. The Fund's "average annual total return" represents an
annualization of the Fund's total return over a particular period and is
computed by finding the annual percentage rate which will result in the ending
redeemable value of a hypothetical $1,000 investment made at the beginning of a
one, five or ten year period, or for the period from the date of commencement of
operations, if shorter than any of the foregoing. The ending redeemable value is
reduced by any contingent deferred sales charge ("CDSC") at the end of the one,
five, 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
(which in the case of Class A shares is reduced by the Class A initial sales
charge), 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 for Class B for the one year, five year and ten year
periods ended December 31, 1998 were 0.67%, -4.51% and 6.81%, respectively. The
average annual total returns of Class A for the fiscal year ended December 31,
1998 and for the period July 28, 1997 (inception of the Class) through December
31, 1998 were 1.02% and 2.69%, respectively. The average annual total returns of
Class C for the fiscal year ended December 31, 1998 and for the period July 28,
1997 (inception of the Class) through December 31, 1998 were 4.23% and 5.66%,
respectively. The average annual total returns of Class D for the fiscal year
ended December 31, 1998 and for the period July 28, 1997 (inception of the
Class) through December 31, 1998 were 5.77% and 6.32%, respectively.
 
                                       34
<PAGE>
    In addition, 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. These 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 above, but without deduction for any
applicable sales charge. Based on this calculation, the average annual total
returns of Class B for the one year, five year and ten year periods ended
December 31, 1998, were 5.63%, 4.83% and 6.81%, respectively. The average annual
total returns of Class A for the fiscal year ended December 31, 1998 and for the
period July 28, 1997 through December 31, 1998 were 5.50% and 5.87%,
respectively. The average annual total returns of Class C for the fiscal year
ended December 31, 1998 and for the period July 28, 1997 through December 31,
1998 were 5.22% and 5.66%, respectively. The average annual total returns of
Class D for the fiscal year ended December 31, 1998 and for the period July 28,
1997 through December 31, 1998 were 5.77% and 6.32%, respectively.
 
    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 total
returns for Class B for the one year, five year and ten year periods ended
December 31, 1998, were 5.63%, 26.61% and 93.24%, respectively. The total
returns of Class A for the fiscal year ended December 31, 1998 and for the
period July 28, 1997 through December 31, 1998 were 5.50% and 8.48%,
respectively. The total returns of Class C for the fiscal year ended December
31, 1998 and for the period July 28, 1997 through December 31, 1998 were 5.22%
and 8.17%, respectively. The total returns of Class D for the fiscal year ended
December 31, 1998 and for the period July 28, 1997 through December 31, 1998
were 5.77% and 9.13%, respectively.
 
    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 each Class at
inception of the Class would have grown to the following amounts at December 31,
1998:

XII. FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
 
    EXPERTS.  The financial statements of the Fund for the fiscal year ended
December 31, 1998 included in this STATEMENT OF ADDITIONAL INFORMATION and
incorporated by reference in the PROSPECTUS have been so included and
incorporated in reliance on the report of PricewaterhouseCoopers LLP,
independent accountants, given on the authority of said firm as experts in
auditing and accounting.

<PAGE>
    This STATEMENT OF ADDITIONAL INFORMATION and the PROSPECTUS do not contain
all of the information set forth in the REGISTRATION STATEMENT the Fund has
filed with the SEC. The complete REGISTRATION STATEMENT may be obtained from the
SEC.
 
    The Fund generally intends to distribute sufficient income and gains so that
the Fund will not pay corporate income tax on its earnings. The Fund also
generally intends to distribute to its shareholders in each calendar year a
sufficient amount of ordinary income and capital gains to avoid the imposition
of a 4% excise tax. However, the Fund may instead determine to retain all or
part of any ordinary income or capital gains in any year for reinvestment. In
such event, the Fund will pay federal income tax (and possibly excise tax) on
such retained gains.
 
    Gains or losses on sales of securities by the Fund will be long-term capital
gains or losses if the securities have a tax holding period of more than one
year. Gains or losses on the sale of securities with a tax holding period of one
year or less will be short-term gains or losses.
 
    In computing net investment income, the Fund will amortize any premiums and
original issue discounts on securities owned, if applicable. Capital gains or
losses realized upon sale or maturity of such securities will be based on their
amortized cost.

FINANCIAL HIGHLIGHTS
 
        The financial highlights table is intended to help you understand the
        Fund's financial performance for the past 5 fiscal years of the Fund.
        Certain information reflects financial results for a single Fund share.

        earned or lost on an investment in the Fund (assuming reinvestment of
        all dividends and distributions).
 
        This information has been audited by PricewaterhouseCoopers LLP,
        independent accountants, whose report, along with the Fund's financial
        statements, is included in the annual report, which is available upon

MORGAN STANLEY DEAN WITTER CALIFORNIA TAX-FREE INCOME FUND
NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1998
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Morgan Stanley Dean Witter California Tax-Free Income Fund (the "Fund"),
formerly Dean Witter California Tax-Free Income 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. On July 28, 1997, the Fund commenced offering three
additional classes of shares, with the then current shares designated as Class B
shares.
 
The Fund offers Class A shares, Class B shares, Class C shares and Class D
shares. The four classes are substantially the same except that most Class A
shares are subject to a sales charge imposed at the time of purchase and some
Class A shares, and most Class B shares and Class C shares are subject to a
contingent deferred sales charge imposed on shares redeemed within one year, six
years and one year, respectively. Class D shares are not subject to a sales
charge. Additionally, Class A shares, Class B shares and Class C shares incur
distribution expenses.
 
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.

MORGAN STANLEY DEAN WITTER CALIFORNIA TAX-FREE INCOME FUND
NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1998, CONTINUED
 
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. MULTIPLE CLASS ALLOCATIONS -- Investment income, expenses (other than
distribution fees), and realized and unrealized gains and losses are allocated
to each class of shares based upon the relative net asset value on the date such
items are recognized. Distribution fees are charged directly to the respective
class.
 
D. 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.
 
E. 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 Morgan Stanley Dean Witter
Advisors Inc. (the "Investment Manager"), formerly Dean Witter InterCapital
Inc., 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 daily
net assets not exceeding $500 million; 0.525% to the portion of daily net assets
exceeding $500 million but not exceeding $750 million; 0.50% to the portion of
daily net assets exceeding

<PAGE>
MORGAN STANLEY DEAN WITTER CALIFORNIA TAX-FREE INCOME FUND
NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1998, CONTINUED
 
$750 million but not exceeding $1 billion; 0.475% to the portion of daily net
assets exceeding $1 billion but not exceeding $1.25 billion; and 0.45% to the
portion of 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 Morgan Stanley 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. The Plan provides that the Fund will pay the Distributor a fee which is
accrued daily and paid monthly at the following annual rates: (i) Class A -- up
to 0.25% of the average daily net assets of Class A; (ii) Class B -- 0.75% of
the lesser of: (a) the average daily aggregate gross sales of the Class B shares
since the inception of the Fund (not including reinvestment of dividend or
capital gain distributions) less the average daily aggregate net asset value of
the Class B shares redeemed since the Fund's inception upon which a contingent
deferred sales charge has been imposed or waived; or (b) the average daily net
assets of Class B; and (iii) Class C -- up to 0.75% of the average daily net
assets of Class C. In the case of Class A shares, amounts paid under the Plan
are paid to the Distributor for services provided. In the case of Class B and
Class C shares, amounts paid under the Plan are paid to the Distributor for (1)
services provided and the expenses borne by it and others in the distribution of
the shares of these Classes, including the payment of commissions for sales of
these Classes and incentive compensation to, and expenses of, the Morgan Stanley
Dean Witter Financial Advisors and others who engage in or support distribution
of the shares or who service shareholder accounts, including overhead and
telephone expenses;(2) printing and distribution of prospectuses and reports
used in connection with the offering of these shares to other than current
shareholders; and (3) 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 Dean Witter
Reynolds Inc.

("DWR"), an affiliate of the Investment Manager and Distributor, and other
selected broker-dealers for their opportunity costs in advancing such amounts,
which compensation would be in the form of a carrying charge on any unreimbursed
expenses.
 
In the case of Class B shares, provided that the Plan continues in effect, any
cumulative expenses incurred by the Distributor but not yet recovered may be
recovered through the payment of future distribution fees from the Fund pursuant
to the Plan and contingent deferred sales charges paid by investors upon
redemption of Class B shares. 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 there were no excess expenses as of
December 31, 1998.
 
For the year ended December 31, 1998, the Distributor rebated a portion of the
distribution fees paid by the fund on Class B shares in the amount of
$3,465,883.
 
In the case of Class A shares 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 credit to Morgan Stanley Dean Witter Financial Advisors or other
selected broker-dealer representatives may be reimbursed in the subsequent
calendar year. For the year ended December 31, 1998, the distribution fee was
accrued for Class A shares and Class C shares at the annual rate of 0.25% and
0.75%, respectively.
 
The Distributor has informed the Fund that for the year ended December 31, 1998,
it received contingent deferred sales charges from certain redemptions of the
Fund's Class B shares and Class C shares of $694,975 and $1,943, respectively
and received $43,401 in front-end sales charges from sales of the Fund's Class A
shares. The respective shareholders pay such charges which are not an expense of
the Fund.
 
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, 1998 aggregated
$171,196,945 and $211,293,988, respectively.

MORGAN STANLEY DEAN WITTER CALIFORNIA TAX- FREE
INCOME FUND
REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND TRUSTEES
OF MORGAN STANLEY 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 Morgan Stanley Dean Witter
California Tax-Free Income Fund (the "Fund"), formerly Dean Witter California
Tax-Free Income Fund, at December 31, 1998, 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 periods
presented, 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, 1998 by correspondence with the custodian and brokers, provide a
reasonable basis for the opinion expressed above.

RATINGS OF INVESTMENTS
 
MOODY'S INVESTORS SERVICE INC. ("MOODY'S")
 
                             MUNICIPAL BOND RATINGS
 
<TABLE>
<S>        <C>
Aaa        Bonds which are rated Aaa are judged to be of the best quality. They carry the
           smallest degree of investment risk and are generally referred to as "gilt edge."
           Interest payments are protected by a large or by an exceptionally stable margin and
           principal is secure. While the various protective elements are likely to change, such
           changes as can be visualized are most unlikely to impair the fundamentally strong
           position of such issues.
 
Aa         Bonds which are rated Aa are judged to be of high quality by all standards. Together
           with the Aaa group they comprise what are generally known as high grade bonds. They
           are rated lower than the best bonds because margins of protection may not be as large
           as in Aaa securities or fluctuation of protective elements may be of greater
           amplitude or there may be other elements present which make the long-term risks
           appear somewhat larger than in Aaa securities.
 
A          Bonds which are rated A possess many favorable investment attributes and are to be
           considered as upper medium grade obligations. Factors giving security to principal
           and interest are considered adequate, but elements may be present which suggest a
           susceptibility to impairment sometime in the future.
 
Baa        Bonds which are rated Baa are considered as medium grade obligation; 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 a 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.
</TABLE>
 
    CONDITIONAL RATING:  Bonds for which the security depends upon the
completion of some act of 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.
 
                                       54
<PAGE>
    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.
 
                             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.
Issuers 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 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.
 
                                       55
<PAGE>
 
<TABLE>
<S>        <C>
AAA        Debt rated "AAA" has the highest rating assigned by Standard & Poor's. Capacity to
           pay interest and repay principal is extremely strong.
 
AA         Debt rated "AA" has a very strong capacity to pay interest and repay principal and
           differs from the highest-rated issues only in small degree.
 
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.
 
Cl         The rating "Cl" 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.
</TABLE>
 
                                       56
<PAGE>
<TABLE>
<S>        <C>
           The foregoing ratings are sometimes followed by a "p" which indicates that the rating
           is provisional. A provisional rating assumes the successful completion of the project
           being financed by the bonds being rated and indicates that payment of debt service
           requirements is largely or entirely dependent upon the successful and timely
           completion of the project. This rating, however, while addressing credit quality
           subsequent to completion of the project, makes no comment on the likelihood or risk
           of default upon failure of such completion.
</TABLE>
 
                             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 commerical 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 payments 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.

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


<PAGE>

their undertakings to repay the Registrant unless their conduct is later
determined to permit indemnification.

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

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

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

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

              Amendment dated June 22, 1998 to the Declaration of Trust
               (the "Declaration") of Dean Witter California Tax-Free
                           Daily Income Fund (the "Trust")
                                 dated April 9, 1984


     WHEREAS, the Trust was established by the Declaration on the date
hereinabove set forth under the laws of the Commonwealth of Massachusetts; and

     WHEREAS, the Trustees of the Trust have deemed it advisable to change the
name of the Trust to " Morgan Stanley Dean Witter California Tax-Free  Income
Fund," such change to be effective on June 22,1998;

NOW, THEREFORE:

     1.  Section 1.1 of Article I of the Declaration is hereby amended so that
that Section shall read in its entirety as follows:

           "Section 1.1  NAME.  The name of the Trust created hereby is the
           Morgan Stanley Dean Witter California Tax-Free Income Fund
           and so far as may be practicable the Trustees shall conduct the
           Trust's activities, execute all documents and sue or be sued under
           that name, which name (and the word "Trust" whenever herein used)
           shall refer to the Trustees as Trustees, and not as individuals, or
           personally, and shall not refer to the officers, agents, employees
           or Shareholders of the Trust.  Should the Trustees determine that
           the use of such name is not advisable, they may use such other name
           for the Trust as they deem proper and the Trust may hold its
           property and conduct its activities under such other name."

     2.  Subsection (n) of Section 1.2 of Article I of the Declaration is hereby
amended so that that Subsection shall read in its entirety as follows:

           "Section 1.2  DEFINITIONS...

           "(n) "TRUST" means the Morgan Stanley Dean Witter California
           Tax-Free Income Fund."

     3.  Section 11.7 of Article XI of the Declaration is hereby amended so that
that Section shall read as follows:

           "Section 11.7  USE OF THE NAME "MORGAN STANLEY DEAN WITTER."  Morgan
           Stanley Dean Witter & Co. ("MSDW") has consented to the use by the
           Trust of the identifying name "Morgan Stanley Dean Witter," which is
           a property right of MSDW.  The Trust will only use the name "Morgan
           Stanley Dean Witter" as a component of its name and for no other
           purpose, and will not purport to grant to any third party the right
           to use the name "Morgan Stanley Dean Witter" for any purpose.  MSDW,
           or any

<PAGE>

           corporate affiliate of MSDW, may use or grant to others the right to
           use the name "Morgan Stanley Dean Witter," or any combination or
           abbreviation thereof, as all or a portion of a corporate or business
           name or for any commercial purpose, including a grant of such right
           to any other investment company.  At the request of MSDW or any
           corporate affiliate of MSDW, the Trust will take such action as may
           be required to provide its consent to the use of the name "Morgan
           Stanley Dean Witter," or any combination or abbreviation thereof, by
           MSDW or any corporate affiliate of MSDW, or by any person to whom
           MSDW or a corporate affiliate of MSDW shall have granted the right
           to such use.  Upon the termination of any investment advisory
           agreement into which a corporate affiliate of MSDW and the Trust may
           enter, the Trust shall, upon request of MSDW or any corporate
           affiliate of MSDW, cease to use the name "Morgan Stanley Dean
           Witter" as a component of its name, and shall not use the name, or
           any combination or abbreviation thereof, as 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 MSDW or any
           corporate affiliate of MSDW may request to effect the foregoing and
           to reconvey to MSDW any and all rights to such name."

     4. The Trustees of the Trust hereby reaffirm the Declaration, as amended,
in all respects.

     5.  This Amendment 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 the same document.

whenever called by the Trustees or the President of the Trust and whenever
election of a Trustee or Trustees by Shareholders is required by the provisions
of Section 16(a) of the 1940 Act, for that purpose. Meetings of Shareholders
shall also be called by the Secretary upon the written request of the holders of
Shares entitled to vote not less than twenty-five percent (25%) of all the votes
entitled to be cast at such meeting. Such request shall state the purpose or
purposes of such meeting and the matters proposed to be acted on thereat. The
Secretary shall inform such Shareholders of the reasonable estimated cost of
preparing and mailing such notice of the meeting, and upon payment to the Trust
of such costs, the Secretary shall give notice stating the purpose or purposes
of the meeting to all entitled to vote at such meeting. No meeting need be
called upon the request of the holders of Shares entitled to cast less than a
majority of all votes entitled to be cast at such meeting, to consider any
matter which is substantially the same as a matter voted upon at any meeting of
Shareholders held during the preceding twelve months.

   SECTION 3.3. NOTICE OF MEETINGS. Written or printed notice of every
Shareholders' meeting stating the place, date, and purpose or purposes thereof,
shall be given by the Secretary not less than ten (10) nor more than ninety (90)
days before such meeting to each Shareholder entitled to vote at such meeting.
Such notice shall be deemed to be given when deposited in the United States
mail, postage prepaid, directed to the Shareholder at his address as it appears
on the records of the Trust.

   SECTION 3.4 QUORUM AND ADJOURNMENT OF MEETINGS. Except as otherwise provided
by law, by the Declaration or by these By-Laws, at all meetings of Shareholders,
the holders of a majority of the Shares issued and outstanding and entitled to
vote thereat, present in person or represented by proxy, shall be requisite and
shall constitute a quorum for the transaction of business. In the absence of a
quorum, the Shareholders present or represented by proxy and entitled to vote
thereat shall have the power to adjourn the meeting from time to time. The
Shareholders present in person or represented by proxy at any meeting and
entitled to vote thereat also shall have the power to adjourn the meeting from
time to time if the vote required to approve or reject any proposal described in
the original notice of such meeting is not obtained (with proxies being voted
for or against adjournment consistent with the votes for and against the
proposal for which the required vote has not been obtained). The affirmative
vote of the holders of a majority of the Shares then present in person or
represented by proxy shall be required to adjourn any meeting. Any adjourned
meeting may be reconvened without further notice or change in record date. At
any reconvened meeting at which a quorum shall be present, any business may be
transacted that might have been transacted at the meeting as originally called.

   SECTION 3.5. VOTING RIGHTS, PROXIES. At each meeting of Shareholders, each
holder of record of Shares entitled to vote thereat shall be entitled to one
vote in person or by proxy for each Share of beneficial interest of the Trust
and for the fractional portion of one vote for each fractional Share entitled to
vote so registered in his or her name on the records of the Trust on the date
fixed as the record date for the determination of Shareholders entitled to vote
at such meeting. Without limiting the manner in which a Shareholder may
authorize another person or persons to act for such Shareholder as proxy
pursuant hereto, the following shall constitute a valid means by which a
Shareholder may grant such authority:

       (i) A Shareholder may execute a writing authorizing another person or
       persons to act for such Shareholder as proxy. Execution may be
       accomplished by the Shareholder or such Shareholder's authorized officer,
       director, employee, attorney-in-fact or another agent signing such
       writing or causing such person's signature to be affixed to such writing
       by any reasonable means including, but not limited to, by facsimile or
       telecopy signature. No written evidence of authority of a Shareholder's
       authorized officer, director, employee, attorney-in-fact or other agent
       shall be required; and

       (ii) A Shareholder may authorize another person or persons to act for
       such Shareholder as proxy by transmitting or authorizing the transmission
       of a telegram or cablegram or by other means of telephonic, electronic or
       computer transmission to the person who will be the holder of the proxy
       or to a proxy solicitation firm, proxy support service organization or
       like agent duly authorized by the person who will be the holder of the
       proxy to receive such transmission, provided that any such telegram or
       cablegram or other means of telephonic, electronic or computer
       transmission must either set forth or be submitted with information from
       which it can be determined that the telegram, cablegram or other
       transmission was authorized by the Shareholder.

No proxy shall be valid after eleven months from its date, unless otherwise
provided in the proxy. At all meetings of Shareholders, unless the voting is
conducted by inspectors, all questions relating to the qualification of voters
and the validity of proxies and the acceptance or rejection of votes shall be
decided by the chairman of the meeting. In determining whether a telegram,
cablegram or other electronic transmission is valid, the chairman or inspector,
as the case may be, shall specify the information upon which he or she relied.
Pursuant to a resolution of a majority of the Trustees, proxies may be solicited
in the name of one or more Trustees or Officers of the Trust. Proxy
solicitations may be made in writing or by using telephonic or other electronic
solicitation procedures that include appropriate methods of verifying the
identity of the Shareholder and confirming any instructions given thereby.

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

   SECTION 3.7. INSPECTORS OF ELECTION. In advance of any meeting of
Shareholders, the Trustees may appoint Inspectors of Election to act at the
meeting or any adjournment thereof. If Inspectors of Election are not so
appointed, the chairman of any meeting of Shareholders may, and on the
request of any

                                        2
<PAGE>

Shareholder or his proxy shall, appoint Inspectors of Election of the meeting.
In case any person appointed as Inspector fails to appear or fails or refuses to
act, the vacancy may be filled by appointment made by the Trustees in advance of
the convening of the meeting or at the meeting by the person acting as chairman.
The Inspectors of Election shall determine the number of Shares outstanding, the
Shares represented at the meeting, the existence of a quorum, the authenticity,
validity and effect of proxies, shall receive votes, ballots or consents, shall
hear and determine all challenges and questions in any way arising in connection
with the right to vote, shall count and tabulate all votes or consents,
determine the results, and do such other acts as may be proper to conduct the
election or vote with fairness to all Shareholders. On request of the chairman
of the meeting, or of any Shareholder or his proxy, the Inspectors of Election
shall make a report in writing of any challenge or question or matter determined
by them and shall execute a certificate of any facts found by them.

   SECTION 3.8. INSPECTION OF BOOKS AND RECORDS. Shareholders shall have such
rights and procedures of inspection of the books and records of the Trust as are
granted to Shareholders under Section 32 of the Business Corporation Law of the
Commonwealth of Massachusetts.

   SECTION 3.9. ACTION BY SHAREHOLDERS WITHOUT MEETING. Except as otherwise
provided by law, the provisions of these By-Laws relating to notices and
meetings to the contrary notwithstanding, any action required or permitted to be
taken at any meeting of Shareholders may be taken without a meeting if a
majority of the Shareholders entitled to vote upon the action consent to the
action in writing and such consents are filed with the records of the Trust.
Such consent shall be treated for all purposes as a vote taken at a meeting of
Shareholders.

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

                                   ARTICLE IV
                                    TRUSTEES

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

   SECTION 4.2. NOTICE OF SPECIAL MEETINGS. Written notice of special meetings
of the Trustees, stating the place, date and time thereof, shall be given not
less than two (2) days before such meeting to each Trustee, personally, by
telegram, by mail, or by leaving such notice at his place of residence or usual
place of business. If mailed, such notice shall be deemed to be given when
deposited in the United States mail, postage prepaid, directed to the Trustee at
his address as it appears on the records of the Trust. Subject to the provisions
of the 1940 Act, notice or waiver of notice need not specify the purpose of any
special meeting.

   SECTION 4.3. TELEPHONE MEETINGS. Subject to the provisions of the 1940 Act,
any Trustee, or any member or members of any committee designated by the
Trustees, may participate in a meeting of the Trustees, or any such committee,
as the case may be, by means of a conference telephone or similar communications
equipment if all persons participating in the meeting can hear each other at the
same time. Participation in a meeting by these means constitutes presence in
person at the meeting.

   SECTION 4.4. QUORUM, VOTING AND ADJOURNMENT OF MEETINGS. At all meetings of
the Trustees, a majority of the Trustees shall be requisite to and shall
constitute a quorum for the transaction of business. If a quorum is present, the
affirmative vote of a majority of the Trustees present shall be the act of the
Trustees, unless the concurrence of a greater proportion is expressly required
for such action by law, the Declaration or these By-Laws. If at any meeting of
the Trustees there be less than a quorum present, the Trustees present thereat
may adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum shall have been obtained.

                                        3
<PAGE>

   SECTION 4.5. ACTION BY TRUSTEES WITHOUT MEETING. The provisions of these
By-Laws covering notices and meetings to the contrary notwithstanding, and
except as required by law, any action required or permitted to be taken at any
meeting of the Trustees may be taken without a meeting if a consent in writing
setting forth the action shall be signed by all of the Trustees entitled to vote
upon the action and such written consent is filed with the minutes of
proceedings of the Trustees.

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

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

   SECTION 4.8. INDEMNIFICATION OF TRUSTEES, OFFICERS, EMPLOYEES AND AGENTS. (a)
The Trust shall indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending, or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of the Trust) by reason of the fact that he is or
was a Trustee, officer, employee, or agent of the Trust. The indemnification
shall be against expenses, including attorneys' fees, judgments, fines, and
amounts paid in settlement, actually and reasonably incurred by him in
connection with the action, suit, or proceeding, if he acted in good faith and
in a manner he reasonably believed to be in or not opposed to the best interests
of the Trust, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the Trust,
and, with respect to any criminal action or proceeding, had reasonable cause to
believe that his conduct was unlawful.

   (b) The Trust shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or on behalf of the Trust to obtain a judgment or decree in its favor by
reason of the fact that he is or was a Trustee, officer, employee, or agent of
the Trust. The indemnification shall be against expenses, including attorneys'
fees actually and reasonably incurred by him in connection with the defense or
settlement of the action or suit, if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the Trust;
except that no indemnification shall be made in respect of any claim, issue, or
matter as to which the person has been adjudged to be liable for negligence or
misconduct in the performance of his duty to the Trust, except to the extent
that the court in which the action or suit was brought, or a court of equity in
the county in which the Trust has its principal office, determines upon
application that, despite the adjudication of liability but in view of all
circumstances of the case, the person is fairly and reasonably entitled to
indemnity for those expenses which the court shall deem proper, provided such
Trustee, officer, employee or agent is not adjudged to be liable by reason of
his willful misfeasance, bad faith, gross negligence or reckless disregard of
the duties involved in the conduct of his office.

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

                                        4
<PAGE>

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

       (2) The determination shall be made:

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

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

         (iii) By the Shareholders.

     (3) Notwithstanding any provision of this Section 4.8, no person shall be
    entitled to indemnification for any liability, whether or not there is an
    adjudication of liability, arising by reason of willful misfeasance, bad
    faith, gross negligence, or reckless disregard of duties as described in
    Section 17(h) and (i) of the Investment Company Act of 1940 ("disabling
    conduct"). A person shall be deemed not liable by reason of disabling
    conduct if, either:

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

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

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

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

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

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

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

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

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

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

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

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

   (f) The indemnification provided by this Section shall not be deemed
exclusive of any other rights to which a person may be entitled under any
by-law, agreement, vote of Shareholders or disinterested Trustees or otherwise,
both as to action in his official capacity and as to action in another capacity
while holding the office, and shall continue as to a person who has ceased to be
a Trustee, officer, employee, or agent and inure to the benefit of the heirs,
executors and administrators of such person; provided that no

                                        5
<PAGE>

person may satisfy any right of indemnity or reimbursement granted herein or to
which he may be otherwise entitled except out of the property of the Trust, and
no Shareholder shall be personally liable with respect to any claim for
indemnity or reimbursement or otherwise.

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

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

                                    ARTICLE V

of the Trust and may delegate to such committees, in the intervals between
meetings of the Trustees, any or all of the powers of the Trustees in the
management of the business and affairs of the Trust. In the absence of any
member of any such committee, the members thereof present at any meeting,
whether or not they constitute a quorum, may appoint a Trustee to act in place
of such absent member. Each such committee shall keep a record of its
proceedings.

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

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

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

   SECTION 5.3. COMMITTEE ACTION WITHOUT MEETING. The provisions of these
By-Laws covering notices and meetings to the contrary notwithstanding, and
except as required by law, any action required or permitted to be taken at any
meeting of any Committee of the Trustees appointed pursuant to Section 5.1 of
these By-Laws may be taken without a meeting if a consent in writing setting
forth the action shall be signed by all members of the Committee entitled to
vote upon the action and such written consent is filed with the records of the
proceedings of the Committee.

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

                           DIVIDENDS AND DISTRIBUTIONS

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

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

                                  ARTICLE VIII

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

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

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

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

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

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

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

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

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

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

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

                                    ARTICLE X
                                WAIVER OF NOTICE

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

   SECTION 11.1. LOCATION OF BOOKS AND RECORDS. The books and records of the
Trust may be kept outside the Commonwealth of Massachusetts at such place or
places as the Trustees may from time to time determine, except as otherwise
required by law.

   SECTION 11.2 RECORD DATE. The Trustees may fix in advance a date as the
record date for the purpose of determining the Shareholders entitled to (i)
receive notice of, or to vote at, any meeting of Shareholders, or (ii) receive
payment of any dividend or the allotment of any rights, or in order to make a
determination of Shareholders for any other proper purpose. The record date, in
any case, shall not be more than one hundred eighty (180) days, and in the case
of a meeting of Shareholders not less than ten (10) days, prior to the date on
which such meeting is to be held or the date on which such other particular
action requiring determination of Shareholders is to be taken, as the case may
be. In the case of a meeting of Shareholders, the meeting date set forth in the
notice to Shareholders accompanying the proxy statement shall be the date used
for purposes of calculating the 180 day or 10 day period, and any adjourned
meeting may be reconvened without a change in record date. In lieu of fixing a
record date, the Trustees may provide that the transfer books shall be closed
for a stated period but not to exceed, in any case, twenty (20) days. If the
transfer books are closed for the purpose of determining Shareholders entitled
to notice of a vote at a meeting of Shareholders, such books shall be closed for
at least ten (10) days immediately preceding the meeting.

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

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

   SECTION 11.5. ORDERS FOR PAYMENT OF MONEY. All orders or instructions for the
payment of money of the Trust, and all notes or other evidences of indebtedness
issued in the name of the Trust, shall be signed by such officer or officers or
such other person or persons as the Trustees may from time to time designate, or
as may be specified in or pursuant to the agreement between the Trust and the
bank or trust company appointed as Custodian of the securities and funds of the
Trust.

                                   ARTICLE XII
                       COMPLIANCE WITH FEDERAL REGULATIONS

   The Trustees are hereby empowered to take such action as they may deem to be
necessary, desirable or appropriate so that the Trust is or shall be in
compliance with any federal or state statute, rule or regulation with which
compliance by the Trust is required.

                                  ARTICLE XIII
                                   AMENDMENTS

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

    AGREEMENT made as of the 31st day of May, 1997, and amended as of April 30,
1998, 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

    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,

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

     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

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 who are also directors, officers or employees of
the Investment Manager, and provide such office space, facilities and equipment
and such clerical help and
<PAGE>
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 & Co., or any corporate affiliate of the Investment
Manager's parent, may use or grant to others the right to use the name "Dean
Witter," or any combination or abbreviation thereof, as all or a portion of a
corporate or business name or
 
                                       3
<PAGE>
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.

Agreement, as amended, on April 30, 1998 in New York, New York.

                             DISTRIBUTION AGREEMENT
 
    AGREEMENT made as of this 28th day of July, 1997, and amended as of June 22,

    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

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

    (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

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 Financial Advisors, 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 remain in force until April 30, 1999, 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 amended, on June 22, 1998 in New York, New York.

                  MORGAN STANLEY DEAN WITTER DISTRIBUTORS INC.
                       OMNIBUS SELECTED DEALER AGREEMENT
 
Dear Sir or Madam:
 
    We,  Morgan Stanley Dean Witter Distributors Inc. (the "Distributor") have a
distribution agreement (the "Distribution Agreement") with each of the  open-end
investment  companies listed  in Schedule  A attached  hereto (each,  a "Fund"),
pursuant to which we act as the  Distributor for the sale of each Fund's  shares
of  common stock  or beneficial  interest, as the  case may  be, (the "Shares").
Under the Distribution  Agreement, we have  the right to  distribute Shares  for
resale.
 
    Each  Fund is an open-end management investment company registered under the
Investment Company Act of 1940, as amended, and the Shares being offered to  the
public  are  registered  under  the  Securities Act  of  1933,  as  amended (the
"Securities Act").  You have  received  a copy  of the  Distribution  Agreements
between  us and each Fund and reference  is made herein to certain provisions of
such Distribution Agreements. The terms used herein, including "Prospectus"  and
"Registration  Statement" of each Fund and "Selected Dealer" shall have the same
meaning in this Agreement  as in the Distribution  Agreements. As principal,  we
offer to sell Shares to your customers, upon the following terms and conditions:
 
    1.  In all sales  of Shares to  the public you  shall act on  behalf of your
customers which for  purposes of  this Agreement  are limited  to customers  for
which  Nations  Banc Investments,  Inc.  is the  Introducing  Broker, and  in no
transaction shall you have any authority to act  as agent for a Fund, for us  or
for any Selected Dealer.
 
    2.  Orders received from  you will be  accepted through us  or on our behalf
only at the public offering price applicable to each order, as set forth in  the
applicable  current Prospectus. The procedure relating to the handling of orders
shall be subject to written instructions  which we or the applicable Fund  shall
forward  from  time to  time to  you. All  orders are  subject to  acceptance or
rejection by us or a Fund in  the sole discretion of either. The Distributor  of
the Fund will promptly notify you in writing of any such rejection.
 
    3.  You  shall not  place  orders for  any  Shares unless  you  have already
received purchase orders for such Shares at the applicable public offering price
and subject to the terms hereof and of the applicable Distribution Agreement and
Prospectus. In  connection herewith,  you agree  to abide  by the  terms of  the
applicable   Distribution  Agreement  and  Prospectus  to  the  extent  required
hereunder. Furthermore, you agree  that (i) you  will offer or  sell any of  the
Shares  only  under  circumstances  that  will  result  in  compliance  with all
applicable Federal and state securities laws; (ii) you will not furnish or cause
to be furnished to any  person any information relating  to the Shares which  is
inconsistent  in any  respect with the  information contained  in the applicable
Prospectus (as then amended or supplemented)  or cause any advertisements to  be
published  by radio or  television or in  any newspaper or  posted in any public
place or use any sales promotional material without our consent and the  consent
of  the applicable  Fund; and  (iii) you  will endeavor  to obtain  proxies from
purchasers of Shares. You also agree that you will be liable to Distributor  for
payment  of the purchase  price for Shares  purchased by customers  and that you
shall make payment for such shares when due.
 
    4. We will  compensate you for  sales of  shares of the  Funds and  personal
services  to  Fund  shareholders  by  paying you  a  sales  charge  and/or other
commission (which may be in  the form of a gross  sales credit and/or an  annual
residual  commission) and/or a service fee, each as separately agreed by you and
us with respect to each Fund.
 
    5. If any Shares sold  to your customers under  the terms of this  Agreement
are  repurchased by us for the account of  a Fund or are tendered for redemption
within seven business days  after the date of  the confirmation of the  original
purchase  by you, it is agreed that you  shall forfeit your right to, and refund
to us, any commission received by you with respect to such Shares.
 
    6. No person is authorized to make any representations concerning the Shares
or the Funds except those contained in the current applicable Prospectus and  in
such  printed information  subsequently issued  by us  or a  Fund as information
supplemental to such Prospectus. In selling Shares, you shall rely solely on the
representations  contained  in  the   applicable  Prospectus  and   supplemental
information  mentioned above. Any printed information which we furnish you other
than the Prospectus and the Funds' periodic reports and
<PAGE>
proxy  solicitation  materials   are  our  sole   responsibility  and  not   the
responsibility  of  the  Funds, and  you  agree  that the  Funds  shall  have no
liability or responsibility to you in these respects unless expressly assumed in
connection therewith.
 
    7. You are hereby authorized (i) to place orders directly with a Fund or its
agent for shares of the  Fund to be sold by  us subject to the applicable  terms
and  conditions  governing the  placement  of orders  for  the purchase  of Fund
Shares, as set forth  in the Distribution Agreement,  and (ii) to tender  Shares
directly to the Fund or its agent for redemption subject to the applicable terms
and conditions set forth in the Distribution Agreement. We will provide you with
copies of any updates to the Distribution Agreement.
 
    8.  We reserve the right in our discretion, without notice, to suspend sales
or withdraw the offering of Shares entirely. Each party hereto has the right  to
cancel  this agreement with respect to one or more Funds upon fifteen days prior
written notice to the other party.
 
    9. I. You shall indemnify and hold us harmless from and against any and  all
losses,  costs,  (including  reasonable  attorney's  fees)  claims,  damages and
liabilities which arise  as a result  of action taken  pursuant to  instructions
from  you, or on your behalf  to: (a)(i) place orders for  Shares of a Fund with
the Fund's transfer agent or direct  the transfer agent to receive  instructions
for  the order  of Shares, and  (ii) accept  monies or direct  that the transfer
agent accept monies as payment for the order of such Shares, all as contemplated
by and in accordance  with Section 3 of  the applicable Distribution  Agreement;
(b)(i)  place orders  for the  redemption of  Shares of  a Fund  with the Fund's
transfer agent  or direct  the transfer  agent to  receive instruction  for  the
redemption  of such Shares and (ii) to pay redemption proceeds or to direct that
the transfer agent  pay redemption proceeds  in connection with  orders for  the
redemption of Shares, all as contemplated by and in accordance with Section 4 of
the  applicable Distribution Agreement; Distributor agrees to indemnify and hold
harmless you  and  your affiliates,  officers,  directors, control  persons  and
employees  from  and against  any and  all  losses, costs  (including reasonable
attorney's fees), claims,  damages and liabilities  which arise as  a result  of
Distributor's  failure to fulfill its obligations hereunder and from any alleged
inaccuracy, omission or  misrepresentation contained  in any  prospectus or  any
advertising,  or sales literature prepared by  Distributor or the Fund provided,
however, that in no case, (i) is this indemnity in favor of you or us and any of
other party's such controlling persons  to be deemed to  protect us or any  such
controlling  persons against any  liability to which we  or any such controlling
persons would otherwise be subject by  reason of willful misfeasance, bad  faith
or  gross negligence in the  performance of our duties  or by reason of reckless
disregard of our obligations and duties  under this Agreement or the  applicable
Distribution  Agreement;  or  (ii) are  you  to  be liable  under  the indemnity
agreement contained in this paragraph with respect to any claim made against  us
or  any such controlling persons, unless we  or any such controlling persons, as
the case may be,  shall have notified  you 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  us or such  controlling persons  (or
after  we or such controlling persons shall have received notice of such service
on any designated agent), notwithstanding the failure to notify you of any  such
claim  shall not relieve you from any liability which you may have to the person
against whom such action is brought  otherwise than on account of the  indemnity
agreement contained in this paragraph.
 
    II.  You will be entitled to participate at your own expense in the defense,
or, if you so elect, to assume the  defense, of any suit brought to enforce  any
such  liability, but if you  elect to assume the  defense, such defense shall be
conducted by counsel  chosen by you  and reasonably satisfactory  to us or  such
controlling person or persons, defendant or defendants in the suit. In the event
you  elect to assume the defense of any such suit and retain such counsel, we 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 you do not elect to assume the defense of any such suit, you will reimburse
us 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 party
shall  promptly notify the other party to  this Agreement of the commencement of
any litigation or proceedings against it or any of its officers or directors  in
connection with the issuance or sale of the Shares pursuant to this Agreement.

    III. If the indemnification provided for in this Section 9 is unavailable or
insufficient  to hold harmless the Distributor,  as provided above in respect of
any losses,  claims, damages,  liabilities or  expenses (or  actions in  respect
thereof)  referred to herein,  then you shall  contribute to the  amount paid or
payable by  us 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  you on the  one hand and  us 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 you
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 your relative fault on the one hand and our relative fault 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. You and  we 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 us
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 us  in connection  with investigating or
defending any  such claim.  Notwithstanding the  provisions of  this  subsection
(III),  you shall  not be  required to  contribute any  amount in  excess of the
amount by which the total  price at which the Shares  distributed by you to  the
public  were offered to the  public exceeds the amount  of any damages which you
have 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 Securities  Act)
shall  be entitled to  contribution from any  person who was  not guilty of such
fraudulent misrepresentation.
 
    IV. Notwithstanding the provisions  of subsections (I),  (II) and (III),  we
shall  indemnify, defend  and hold  harmless you  and your  officers, directors,
employees, affiliates, agents, successors and  assigns from and against any  and
all  claims  and all  related losses,  expenses,  damages, cost  and liabilities
including reasonable attorneys' fees and  expenses incurred in investigation  or
defense, arising out of or related to any breach of any representation, warranty
or covenant by us contained in Section 15 of this Agreement.
 
    11.  We  shall  have full  authority  to take  such  action as  we  may deem
advisable  in  respect  of  all  matters  pertaining  to  the  distribution  and
redemption  of Shares. Neither party  shall be under any  liability to the other
party except  for lack  of  good faith  and  for obligations  expressly  assumed
herein.  Nothing contained in this paragraph is  intended to operate as, and the
provisions of  this paragraph  shall not  in any  way whatsoever  constitute,  a
waiver  by you of compliance with any provision of the Securities Act, or of the
rules  and  regulations  of  the  Securities  and  Exchange  Commission   issued
thereunder.
 
    12.  Each  party represents  that it  is a  member in  good standing  of the
National Association of Securities Dealers, Inc. and, with respect to any  sales
in  the United States,  each party hereby agrees  to abide by  the Rules of Fair
Practice of  such Association  relating to  the performance  of the  obligations
hereunder.
 
    13.  We will inform you in writing as  to the states in which we believe the
Shares have been qualified for sale  under, or are exempt from the  requirements
of,   the  respective  securities  laws  of   such  states,  but  we  assume  no
responsibility  or  obligation  as  to  your   right  to  sell  Shares  in   any
jurisdiction.
 
    14.  Notwithstanding any other provision of  this Agreement to the contrary,
we represent and  warrant that  the names and  addresses of  your customers  (or
customers  of your affiliates) which have or  which may come to our attention in
connection with this Agreement are confidential and are your exclusive  property
and  shall  not  be utilized  by  us  except in  connection  with  the functions
performed  by  us  in  connection  with  this  Agreement.  Notwithstanding   the
foregoing, should a customer request, that we or an organization affiliated with
us,  provide services to such customer, we or such affiliated organization shall
in no way violate this representation and warranty, nor be considered in  breach
of this Agreement.
 
    15. We represent, warrant, and covenant to you that the marketing materials,
any  communications distributed to the public and training materials designed by
us or our agents relating to the product sold under this Agreement are true  and
accurate   and  do   not  omit   to  state   a  fact   necessary  to   make  the
 
                                       3
<PAGE>
information contained therein not misleading and comply with applicable  federal
and  state laws.  We further  represent, warrant, and  covenant to  you that the
performance by us of our obligations under this Agreement in no way  constitutes
an  infringement on  or other violation  of copyright,  trade secret, trademark,
proprietary information or non-disclosure rights of any other party.
 
    16. We shall  maintain a  contingency disaster  recovery plan,  and, in  the
event  you are so  required by any  regulatory or governmental  agency, we shall
make such plan available  to you for inspection  at your office upon  reasonable
advance  notice by you. Each party agrees that  it will at all times conduct its
activities under this Agreement in an equitable, legal and professional manner.
 
    17. We understand  that the performance  of your and  our obligations  under
this  Agreement  is  subject  to  examination  during  business  hours  by  your
authorized representatives  and auditors  and by  federal and  state  regulatory
agencies,  and  we agree  that  upon being  given  reasonable notice  and proper
identification we shall submit or furnish at a reasonable time and place to  any
such  representative or  regulatory agency  reports, information,  or other data
relating to this Agreement as may reasonably be required or requested by you. We
shall maintain and make  available to you upon  reasonable notice all  material,
data,  files, and records  relating to this  Agreement for a  period of not less
than three years after the termination of this Agreement.
 
    18. The  sales, advertising  and promotional  materials designed  by  either
party  or its agents relating to products sold under this Agreement shall comply
with applicable  federal and  state  laws. Each  party  agrees that  the  sales,
advertising and promotional materials shall be made available to the other party
prior to distribution to your employees or customers.
 
    19. Any controversy or claim between or among the parties hereto arising out
of  or relating to this Agreement, including  any claim based on or arising from
an alleged tort, shall be determined  by binding arbitration in accordance  with
the  rules of the National Association of Securities Dealers, Inc. Judgment upon
any arbitration award may be entered in any court having jurisdiction. Any party
to this  Agreement  may  bring  an action,  including  a  summary  or  expedited
proceeding,  to compel  arbitration of  any controversy  or claim  to which this
Agreement applies in any court having jurisdiction over such action.
 
    20. All notices  or other communications  under this Agreement  shall be  in
writing and given as follows:

                               SERVICES AGREEMENT
 
    AGREEMENT made as of the 17th day of April, 1995, and amended as of June 22,
1998, by and between Morgan Stanley Dean Witter Advisors Inc., a Delaware
corporation (herein referred to as "MSDW Advisors"), and Morgan Stanley Dean
Witter Services Company Inc., a Delaware corporation (herein referred to as
"MSDW Services").
 
    WHEREAS, MSDW Advisors has entered into separate agreements (each such
agreement being herein referred to as an "Investment Management Agreement") with
certain investment companies as set forth on Schedule A (each such investment
company being herein referred to as a "Fund" and, collectively, as the "Funds")
pursuant to which MSDW Advisors is to perform, or supervise the performance of,
among other services, administrative services for the Funds (and, in the case of
Funds with multiple portfolios, the Series or Portfolios of the Funds (such
Series and Portfolio being herein individually referred to as "a Series" and,
collectively, as "the Series"));
 
    WHEREAS, MSDW Advisors desires to retain MSDW Services to perform the
administrative services as described below; and
 
    WHEREAS, MSDW Services desires to be retained by MSDW Advisors to perform
such administrative services:
 
    Now, therefore, in consideration of the mutual covenants and agreements of
the parties hereto as herein set forth, the parties covenant and agree as
follows:
 
    1. MSDW Services agrees to provide administrative services to each Fund as
hereinafter set forth. Without limiting the generality of the foregoing, MSDW
Services shall (i) administer the Fund's business affairs and supervise the
overall day-to-day operations of the Fund (other than rendering investment
advice); (ii) provide the Fund with full administrative services, including the
maintenance of certain books and records, such as journals, ledger accounts and
other records required under the Investment Company Act of 1940, as amended (the
"Act"), the notification to the Fund and MSDW Advisors of available funds for
investment, the reconciliation of account information and balances among the
Fund's custodian, transfer agent and dividend disbursing agent and MSDW
Advisors, and the calculation of the net asset value of the Fund's shares; (iii)
provide the Fund with the services of persons competent to perform such
supervisory, administrative and clerical functions as are necessary to provide
effective operation of the Fund; (iv) oversee the performance of administrative
and professional services rendered to the Fund by others, including its
custodian, transfer agent and dividend disbursing agent, as well as accounting,
auditing and other services; (v) provide the Fund with adequate general office
space and facilities; (vi) assist in the preparation and the printing of the
periodic updating of the Fund's registration statement and prospectus (and, in
the case of an open-end Fund, the statement of additional information), tax
returns, proxy statements, and reports to its shareholders and the Securities
and Exchange Commission; and (vii) monitor the compliance of the Fund's
investment policies and restrictions.
 
    In the event that MSDW Advisors enters into an Investment Management
Agreement with another investment company, and wishes to retain MSDW Services to
perform administrative services hereunder, it shall notify MSDW Services in
writing. If MSDW Services is willing to render such services, it shall notify
MSDW Advisors in writing, whereupon such other Fund shall become a Fund as
defined herein.
 
    2. MSDW Services 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 MSDW Services shall be deemed to include
officers of MSDW Services and persons employed or otherwise retained by MSDW
Services (including officers and employees of MSDW Advisors, with the consent of
MSDW Advisors) to furnish services, statistical and other factual data,
information with respect to technical and scientific developments, and such
other information, advice and assistance as MSDW Services may desire. MSDW
Services shall maintain each Fund's records and books of account
 
                                       1
 
98NYC8262
<PAGE>
(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, MSDW Services shall surrender
to MSDW Advisors or to the Fund such of the books and records so requested.
 
    3. MSDW Advisors will, from time to time, furnish or otherwise make
available to MSDW Services such financial reports, proxy statements and other
information relating to the business and affairs of the Fund as MSDW Services
may reasonably require in order to discharge its duties and obligations to the
Fund under this Agreement or to comply with any applicable law and regulation or
request of the Board of Directors/Trustees of the Fund.
 
    4. For the services to be rendered, the facilities furnished, and the
expenses assumed by MSDW Services, MSDW Advisors shall pay to MSDW Services
monthly compensation calculated daily (in the case of an open-end Fund) or
weekly (in the case of a closed-end Fund) by applying the annual rate or rates
set forth on Schedule B to the net assets of each Fund. Except as hereinafter
set forth, (i) in the case of an open-end Fund, compensation under this
Agreement shall be calculated by applying 1/365th of the annual rate or rates to
the Fund's or the Series' daily net assets determined as of the close of
business on that day or the last previous business day and (ii) in the case of a
closed-end Fund, compensation under this Agreement shall be calculated by
applying the annual rate or rates to the Fund's average weekly net assets
determined as of the close of the last business day of each week. 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 on Schedule B. Subject to the
provisions of paragraph 5 hereof, payment of MSDW Services' compensation for the
preceding month shall be made as promptly as possible after completion of the
computations contemplated by paragraph 5 hereof.
 
    5. In the event the operating expenses of any open-end Fund and/or any
Series thereof, or of InterCapital Income Securities Inc., including amounts
payable to MSDW Advisors pursuant to the Investment Management Agreement, for
any fiscal year ending on a date on which this Agreement is in effect, exceed
the expense limitations applicable to the Fund and/or any Series thereof imposed
by state securities laws or regulations thereunder, as such limitations may be
raised or lowered from time to time, or, in the case of InterCapital Income
Securities Inc. or Morgan Stanley Dean Witter Variable Investment Series or any
Series thereof, the expense limitation specified in the Fund's Investment
Management Agreement, the fee payable hereunder shall be reduced on a pro rata
basis in the same proportion as the fee payable by the Fund under the Investment
Management Agreement is reduced.
 
    6. MSDW Services shall bear the cost of rendering the administrative
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
employed by MSDW Services, and such clerical help and bookkeeping services as
MSDW Services shall reasonably require in performing its duties hereunder.
 
    7. MSDW Services will use its best efforts in the performance of
administrative activitives on behalf of each Fund, but in the absence of willful
misfeasance, bad faith, gross negligence or reckless disregard of its
obligations hereunder, MSDW Services 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 MSDW Services or for any losses sustained by the Fund or its
investors. It is understood that, subject to the terms and conditions of the
Investment Management Agreement between each Fund and MSDW Advisors, MSDW
Advisors shall retain ultimate responsibility for all services to be performed
hereunder by MSDW Services. MSDW Services shall indemnify MSDW Advisors and hold
it harmless from any liability that MSDW Advisors may incur arising out of any
act or failure to act by MSDW Services in carrying out its responsibilities
hereunder.
 
    8. It is understood that any of the shareholders, Directors/Trustees,
officers and employees of the Fund may be a shareholder, director, officer or
employee of, or be otherwise interested in, MSDW Services, and in any person
controlling, controlled by or under common control with MSDW Services, and that
MSDW Services and any person controlling, controlled by or under common control
with MSDW
 
                                       2
<PAGE>
Services may have an interest in the Fund. It is also understood that MSDW
Services and any affiliated persons thereof or any persons controlling,
controlled by or under common control with MSDW Services have and may have
advisory, management, administration service or other contracts with other
organizations and persons, and may have other interests and businesses, and
further may purchase, sell or trade any securities or commodities for their own
accounts or for the account of others for whom they may be acting.
 
    9. This Agreement shall continue until April 30, 1999, and thereafter shall
continue automatically for successive periods of one year unless terminated by
either party by written notice delivered to the other party within 30 days of
the expiration of the then-existing period. Notwithstanding the foregoing, this
Agreement may be terminated at any time, by either party on 30 days' written
notice delivered to the other party. In the event that the Investment Management
Agreement between any Fund and MSDW Advisors is terminated, this Agreement will
automatically terminate with respect to such Fund.
 
    10. This Agreement may be amended or modified by the parties in any manner
by written agreement executed by each of the parties hereto.
 
    11. This Agreement may be assigned by either party with the written consent
of the other party.
 
    12. This Agreement shall be construed and interpreted in accordance with the
laws of the State of New York.
 
    IN WITNESS WHEREOF, the parties hereto have executed and delivered this
Agreement, as amended, on June 22, 1998 in New York, New York.

                        MORGAN STANLEY 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"), effective as of
July 28, 1997, and amended as of June 22, 1998. The Plan relates to shares of
the open-end investment companies to which Morgan Stanley Dean Witter Advisors
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 Morgan
Stanley 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 (Morgan Stanley Dean Witter American Value Fund, Morgan
Stanley Dean Witter Natural Resource Development Securities Inc., Morgan Stanley
Dean Witter Strategist Fund and Morgan
 
                                       1
<PAGE>
Stanley Dean Witter Dividend Growth Securities Inc.)(1), Class B 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 Morgan Stanley 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.
 
- ------------
 
(1)The payments under the 12b-1 Plan for each of Morgan Stanley Dean Witter
American Value Fund, Morgan Stanley Dean Witter Natural Resource Development
Securities Inc. and Morgan Stanley 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 Morgan
Stanley 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.
 
                                       2
<PAGE>
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
Morgan Stanley Dean Witter Balanced Growth Fund and Morgan Stanley 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 Morgan Stanley Dean
Witter American Value Fund purchased prior to April 30, 1984, shares of Morgan
Stanley Dean Witter Strategist Fund purchased prior to November 8, 1989 and
shares of Morgan Stanley Dean Witter Natural Resource Development Securities
Inc. and Morgan Stanley 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 Morgan Stanley Dean Witter Balanced Growth Fund and Morgan Stanley
Dean Witter Balanced Income Fund held prior to July 28, 1997 have been
designated Class C shares except that shares of Morgan Stanley Dean Witter
Balanced Growth Fund and Morgan Stanley 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 were purchased before July 28, 1997
by trusts for which Morgan Stanley Dean Witter Trust FSB ("MSDW Trust") provides
discretionary trustee services converted to Class A shares on August 29, 1997
(the CDSC was not 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 plan
qualified under Section 401(a) of the Internal Revenue Code (the "Code") and
 
                                       3
<PAGE>
for which MSDW Trust serves as Trustee or DWR's Retirement Plan Services serves
as recordkeeper pursuant to a written Recordkeeping Services Agreement, 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.
