THE FUND

ICON INVESTMENT OBJECTIVE
- --------------------------------------------------------------------------------
Morgan Stanley Dean Witter Utilities Fund is a mutual fund
that seeks to provide current income and long-term growth of
income and capital. There is no guarantee that the Fund will
achieve these objectives.

On April 22, 1999, the Fund's Board of Trustees unanimously
recommended that the Fund's shareholders approve changing
the Fund's investment objective to: "seek both capital
appreciation and current income." This change would have the
effect of eliminating long-term growth of income as an
objective of the Fund.

ICON PRINCIPAL INVESTMENT STRATEGIES
- --------------------------------------------------------------------------------

The Fund will normally invest at least 65% of its assets in
the common stock, other equity and investment grade
fixed-income securities (including zero coupon securities)
of companies that are engaged in the utilities industry. A
company will be considered to be in the utilities industry
if it derives at least 50% of its revenues or earnings from
the utilities industry or devotes at least 50% of its assets
to activities in the industry. These may include companies
involved in, among other areas: telecommunications, gas and
electric energy, water distribution, the Internet and
Internet related services. The companies may be
traditionally regulated public utilities as well as fully or
partially deregulated utility companies. The Fund's
"Investment Manager," Morgan Stanley Dean Witter Advisors
Inc., will shift the Fund's asset between different types of
utilities and between equity and fixed-income securities,
based on prevailing market, economic and financial
conditions. The Fund does not have any set policies to
concentrate its assets in any particular segment of the
utilities industry or any particular type of security.
However, the Fund's policy to concentrate its assets in the
public utility industry is fundamental, and may not be
changed without shareholder approval. In selecting common
stock and other equity securities, the Investment Manager
considers earnings and dividend growth, book value, dividend
discount and price/earnings relationships. In addition, the
Investment Manager makes continuing assessments of
management, the prevailing regulator's framework and
industry trends. Computer-based equity selection models also
may be used. If the Investment Manager believes favorable
conditions for capital growth of equity securities are not
prevalent at a particular time, it may allocate the Fund's
assets predominantly or exclusively to debt securities with
the aim of obtaining current income and thus benefitting
long-term growth of capital.

Common stock is a share ownership or equity interest in a
corporation. It may or may not pay dividends, as some
companies reinvest all of their profits back into their
businesses, while others pay out some of their profits to
shareholders as dividends. Fixed-income securities, however,
are debt securities such as bonds, notes and commercial
paper. The issuer of a debt security borrows money from the
investor who buys the security. Most debt securities either
pay fixed or adjustable rates of interest at regular
intervals until they mature, at which point investors get
their principal back.

In pursuing the Fund's investment objectives, the Investment
Manager has considerable leeway in deciding which
investments it buys, holds or sells on a day-to-day basis --
and which trading strategies it uses. For example, the
Investment Manager in its discretion may determine to use
some permitted trading strategies while not using others. In
addition to the securities discussed above, the Fund may
make investments in foreign securities and other
investments. For more information about the Fund's
investments, see the "Additional Investment Strategy
Information" section.

<PAGE>
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.

UTILITIES INDUSTRY. The Fund's investments in the utilities
industry are impacted by risks particular to that industry.
Changing regulation constitutes one of the key
industry-specific risks for the Fund, especially with
respect to its investments in traditionally regulated public
utilities and partially regulated utility companies. State
and other regulators monitor and control utility revenues
and costs, and therefore may limit utility profits and
dividends paid to investors. Regulatory authorities also may
restrict a company's access to new markets, thereby
diminishing the company's long-term prospects. Individual
sectors of the utility market are subject to additional
risks. These risks apply to all utility companies --
regulated or fully or partially deregulated. For example,
telecommunications companies have been affected by
technological developments leading to increased competition,
as well as changing regulation of local and long-distance
telephone service and other telecommunications businesses.
Certain telecommunications companies have not benefitted
from the new competitive climate.

Electric utilities may incur unexpected increases in fuel
and other operating costs. They are adversely affected when
long-term interest rates rise. Long-term borrowings are used
to finance most utility investment, and rising interest
rates lead to higher financing costs and reduced earnings.
There are also the considerable costs associated with
environmental compliance, nuclear waste clean-up, and safety
regulation. Increasingly, regulators are calling upon
electric utilities to bear these added costs, and there is a
risk that these costs will not be fully recovered through an
increase in revenues.

Among gas companies, there has been a move to diversify into
oil and gas exploration and development, making investment
returns more sensitive to energy prices. In the case of the
water utility sector, the industry is highly fragmented, and
most water supply companies find themselves in mature
markets, with little potential for growth.

COMMON STOCKS AND OTHER EQUITY SECURITIES. In general, stock
and other equity security values fluctuate in response to
activities specific to the company as well as general
market, economic and political conditions. The prices can
fluctuate widely in response to these factors. This can
especially be the case for fully or partially deregulated
utility companies.

FIXED-INCOME SECURITIES. All fixed-income securities are
subject to two types of risk: credit risk and interest rate
risk. Credit risk refers to the possibility that the issuer
of a security will be unable to make interest payments
and/or repay the principal on its debt. 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.)

FOREIGN SECURITIES. The Fund's investments in foreign
securities (including depository receipts) involve risks in
addition to the risks associated with domestic securities.
See the "Additional Risk Information" section for a
description of these risks.
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. For more
information about these risks, see the "Additional Risk
Information" section.
Shares of the Fund are not bank deposits and are not
guaranteed or insured by any bank, governmental entity, or
the FDIC.

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
- --------------------------------------------------------------------------------
The Fund seeks to provide current income and long-term
growth of income and capital. There is no guarantee that the
Fund will achieve these objectives.

This section provides additional information concerning the
Fund's principal strategies.

FOREIGN SECURITIES. The Fund may invest up to 25% of its
assets in foreign securities, including common stock, other
equity and investment grade fixed-income securities.
However, this percentage limitation does not apply to
securities of foreign companies that are listed in the U.S.
on a national securities exchange.

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
cash or money market instruments in a defensive posture when
the Investment Manager believes it is advisable to do so.
Although taking a defensive posture is designed to protect
the Fund from an anticipated market downturn, it could have
the effect of reducing the benefit from any upswing in the
market.

The percentage limitations relating to the composition of
the Fund's portfolio referenced in "Principal Investment
Strategies" apply at the time the Fund acquires an
investment. Subsequent percentage changes that result from
market fluctuations or changes in assets will not require
the Fund to sell any portfolio security. The Fund may change
its principal investment strategies without shareholder
approval; however, you would be notified of any changes.

ICON ADDITIONAL RISK INFORMATION
- --------------------------------------------------------------------------------
As discussed in the "Principal Risks" section, a principal
risk of investing in the Fund is associated with its common
stock, other equity and fixed-income investments. This
section provides additional information regarding the
principal risks of investing in the Fund.

FOREIGN SECURITIES. The Fund's investments in foreign
securities (including depository receipts) involve risks
that are in addition to the risks associated with domestic
securities. One additional risk is currency risk. While the
price of Fund shares is quoted in U.S. dollars, the Fund
generally converts U.S. dollars to a foreign market's local
currency to purchase a security in that market. If the value
of that local currency falls relative to the U.S. dollar,
the U.S. dollar value of the foreign security will decrease.
This is true even if the foreign security's local price
remains unchanged.

Foreign securities also have risks related to economic and
political developments abroad, including expropriations,
confiscatory taxation, exchange control regulation,
limitations on the use or transfer of Fund assets and any
effects of foreign social, economic or political
instability. In particular, adverse political or economic
developments in the Pacific region and/or a particular
country in which the Fund invests could cause a substantial
decline in value of the portfolio. Foreign companies, in
general, are not subject to the regulatory requirements of
U.S.

MORGAN STANLEY DEAN WITTER ADVISORS INC.

The Investment Manager is widely recognized as a leader in the mutual fund
industry and together with Morgan Stanley Dean Witter Services Company Inc., its
wholly-owned subsidiary, has more than $129 billion in assets under management
or administration as of March 31, 1999.
(End Sidebar)
companies and, as such, there may be less publicly available
information about these companies. Moreover, foreign
accounting, auditing and financial reporting standards
generally are different from those applicable to U.S.
companies. Finally, in the event of a default of any foreign
debt obligations, it may be more difficult for the Fund to
obtain or enforce a judgment against the issuers of the
securities.

Securities of foreign issuers may be less liquid than
comparable securities of U.S. issuers and, as such, their
price changes may be more volatile. Furthermore, foreign
exchanges and broker-dealers are generally subject to less
government and exchange scrutiny and regulation than their
U.S. counterparts.

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 its
affiliates are working hard to avoid any problems and to
obtain assurances from their service providers that they are
taking similar steps.

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. Corporate and governmental data processing errors
also 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.

ICON FUND MANAGEMENT
- --------------------------------------------------------------------------------
The Fund has retained the Investment Manager -- Morgan
Stanley Dean Witter Advisors Inc. -- to provide
administrative services, manage its business affairs and
invest its assets, including the placing of orders for the
purchase and sale of portfolio securities. The Investment
Manager is a wholly-owned subsidiary of Morgan Stanley Dean
Witter & Co., a preeminent global financial services firm
that maintains leading market positions in each of its three
primary businesses: securities, asset management and credit
services. Its main business office is located at Two World
Trade Center, New York, New York 10048.

The Fund's portfolio is managed within the Investment
Manager's Income and Growth Group. Edward F. Gaylor, a
Senior Vice President of the Investment Manager, has been
the primary portfolio manager of the Fund since it commenced
operations and a portfolio manager 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 fiscal year ended December 31, 1998,
the Fund accrued total compensation to the Investment
Manager amounting to 0.54% of the Fund's average daily net
assets.

SHAREHOLDER INFORMATION

ICON 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 is based on the
securities' market price when available. When a market price
is not readily available, including circumstances under
which the Investment Manager determines that a security's
market price is not accurate, a portfolio security is valued
at its fair value, as determined under procedures
established by the Fund's Board of Trustees. In these cases,
the Fund's net asset value will reflect certain portfolio
securities' fair value rather than their market price. In
addition, if the Fund holds securities primarily listed on
foreign exchanges, the value of the Fund's portfolio
securities may change on days when you will not be able to
purchase or sell your shares.

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.

ICON 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.

ICON HOW TO EXCHANGE SHARES
- --------------------------------------------------------------------------------
PERMISSIBLE FUND EXCHANGES. You may exchange shares of any
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.

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(s), policies and
investment minimums, 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.

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.

CDSC CALCULATIONS ON EXCHANGES. See the "Share Class
Arrangements" section of this PROSPECTUS for a discussion of
how applicable contingent deferred sales charges (CDSCs) are
calculated for shares of one Morgan Stanley Dean Witter Fund
that are exchanged for shares of another.

FOR FURTHER INFORMATION REGARDING EXCHANGE PRIVILEGES, YOU
SHOULD CONTACT YOUR MORGAN STANLEY DEAN WITTER FINANCIAL
ADVISOR OR CALL (800) 869-NEWS.

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.

may exhaust your account balance. The Fund may terminate or
revise the plan at any time.
- --------------------------------------------------------------------------------
</TABLE>

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).

TAX CONSIDERATIONS. Normally, your sale of Fund shares is
subject to federal and state income tax. You should review
the "Tax Consequences" section of this PROSPECTUS and
consult your own tax professional about the tax consequences
of a sale.

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.

TARGETED DIVIDENDS-SM-
You may select to have your Fund distributions automatically invested in other
Classes of Fund shares or Classes of another Morgan Stanley Dean Witter Fund
that you own. Contact your Morgan Stanley Dean Witter Financial Advisor for
further information about this service.
(End Sidebar)

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.

ICON DISTRIBUTIONS
- --------------------------------------------------------------------------------
The Fund passes substantially all of its earnings from
income and capital gains along to its investors as
"distributions." The Fund earns income from stocks and
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
usually 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
quarterly 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.

ICON 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.

12
<PAGE>
Unless your investment in the Fund is through a tax-deferred
retirement account, such as a 401(k) plan or IRA, 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 distributions are normally
subject to federal and state income tax when they are paid,
whether you take them in cash or reinvest them in Fund
shares. A distribution also may be subject to local income
tax. Any income dividend distributions and any short-term
capital gain distributions are taxable to you as ordinary
income. Any long-term capital gain distributions are taxable
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.

ICON 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.

13
<PAGE>
(Sidebar)
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.
(End Sidebar)
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.

The chart below compares the sales charge and maximum annual
12b-1 fee applicable to each Class:

</TABLE>

CLASS A SHARES Class A shares are sold at net asset value
plus an initial sales charge of up to 5.25%. The initial
sales charge is reduced for 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
(expressed as a percentage of the offering price) on a
single transaction as shown in the following table:

<TABLE>
<CAPTION>
FRONT-END SALES CHARGE

- ----------------------------------------------------------------------------------------
</TABLE>

The reduced sales charge schedule is applicable to purchases
of Class A shares in a single transaction by:

- A single account (including an individual, trust or
fiduciary account).

- Family member accounts (limited to husband, wife and
children under the age of 21).

- Pension, profit sharing or other employee benefit plans of
companies and their affiliates.

- Tax-exempt organizations.

- Groups organized for a purpose other than to buy mutual
fund shares.

14
<PAGE>
COMBINED PURCHASE PRIVILEGE. You also will have the benefit
of reduced sales charges by combining purchases of Class A
shares of the Fund in a single transaction with purchases of
Class A shares of other Multi-Class Funds and shares of FSC
Funds.

RIGHT OF ACCUMULATION. You also may benefit from a reduction
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 Class A shares of the Fund or
other Multi-Class Funds or shares of FSC Funds within a
thirteen-month period. 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.

CONTINGENT DEFERRED SALES CHARGE OR CDSC
A fee you pay when you sell shares of certain Morgan Stanley Dean Witter Funds
purchased without an initial sales charge. This fee declines the longer you hold
your shares as set forth in the table.
(End Sidebar)

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 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.

- Persons participating in a fee-based investment program
(subject to all of its terms and conditions, including
mandatory sale or transfer restrictions on termination)
approved by the Fund's distributor pursuant to which they
pay an asset-based fee for investment advisory,
administrative and/or brokerage services.

- Employer-sponsored employee benefit plans, whether or not
qualified under the Internal Revenue Code, for which
Morgan Stanley Dean Witter Trust FSB serves as trustee or
Dean Witter Reynolds' Retirement Plan Services serves as
recordkeeper under a written Recordkeeping Services
Agreement ("MSDW Eligible Plans") which have at least 200
eligible employees.

- A MSDW Eligible Plan whose Class B shares have converted
to Class A shares, regardless of the plan's asset size or
number of eligible employees.

- A client of a Morgan Stanley Dean Witter Financial Advisor
who joined us from another investment firm within six
months prior to the date of purchase of Fund shares, and
you used the proceeds from the sale of shares of a
proprietary mutual fund of that Financial Advisor's
previous firm that imposed either a front-end or deferred
sales charge to purchase Class A shares, provided that:
(1) you sold the shares not more than 60 days prior to the
purchase of Fund shares, and (2) the sale proceeds were
maintained in the interim in cash or a money market fund.

- Current or retired Directors/Trustees of the Morgan
Stanley Dean Witter Funds, such persons' spouses and
children under the age of 21, and trust accounts for which
any of such persons is a beneficiary.

- Current or retired directors, officers and employees of
Morgan Stanley Dean Witter & Co. and any of its
subsidiaries, such persons' spouses and children under the
age of 21, and trust accounts for which any of such
persons is a beneficiary.

CLASS B SHARES Class B shares are offered at net asset
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,
shares are deemed to have been purchased on the last day of
the month during which they were purchased.

</TABLE>

16
<PAGE>
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 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 held for you as a participant in a MSDW
Eligible Plan.

- 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 subject to an annual
12b-1 fee of 1.0% 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 reinvestments 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.

17
<PAGE>
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.)
In the case of Class B shares held in a MSDW Eligible Plan,
the plan is treated as a single investor and all Class B
shares will convert to Class A shares on the conversion date
of the Class B shares of a Morgan Stanley Dean Witter Fund
purchased by that plan.

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.
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, if any, 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.

18
<PAGE>
CLASS C SHARES Class C shares are sold at net asset value
with no initial sales charge but are subject to a CDSC of up
to 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 up to 1.0% 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.

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 ($25 million for MSDW Eligible Plans) and the
following investor categories:

- Investors participating in the Investment Manager's mutual
fund asset allocation program (subject to all of its terms
and conditions, including mandatory sale or transfer
restrictions on termination) pursuant to which they pay an
asset-based fee.

- Employee benefit plans maintained by Morgan Stanley Dean
Witter & Co. or any of its subsidiaries for the benefit of
certain employees of Morgan Stanley Dean Witter & Co. and
its subsidiaries.

- Certain unit investment trusts sponsored by Dean Witter
Reynolds.

- Certain other open-end investment companies whose shares
are distributed by the Fund's distributor.

- Investors who were shareholders of the Dean Witter
Retirement Series on September 11, 1998 for additional
purchases for their former Dean Witter Retirement Series
accounts.

MEETING CLASS D ELIGIBILITY MINIMUMS. To meet the $5 million
($25 million for certain MSDW Eligible Plans) 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.

19
<PAGE>
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 as a "Massachusetts business trust" under the laws of
the Commonwealth of Massachusetts on December 8, 1987 under the name Dean Witter
Utilities Fund. Effective June 22, 1998, the Fund's name was changed to Morgan
Stanley Dean Witter Utilities 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 seek to provide current income and long-term growth
of income and 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."

OPTION AND FUTURES TRANSACTIONS. The Fund may engage in transactions in
listed and OTC options. Listed options are issued or guaranteed by the exchange
on which they are traded or by a clearing corporation such as the Options
Clearing Corporation ("OCC"). Ownership of a listed call option gives the Fund
the right to buy from the OCC (in the U.S.) or other clearing corporation or
exchange, the underlying security or currency covered by the option at the
stated exercise price (the price per unit of the underlying security) by filing
an exercise notice prior to the expiration date of the option. The writer
(seller) of the option would then have the obligation to sell to the OCC (in the
U.S.) or other clearing corporation or exchange, the underlying security or
currency at that exercise price prior to the expiration date of the option,
regardless of its then current market price. Ownership of a listed put option
would give the Fund the right to sell the underlying security or currency to the
OCC (in the U.S.) or other clearing corporation or exchange, at the stated
exercise price. Upon notice of exercise of the put option, the writer of the put
would have the obligation to purchase the underlying security or currency from
the OCC (in the U.S.) or other clearing corporation or exchange, at the exercise
price.

COVERED CALL WRITING. The Fund is permitted to write covered call options
on portfolio securities, without limit.

The Fund will receive from the purchaser, in return for a call it has
written, a "premium;" i.e., the price of the option. Receipt of these premiums
may better enable the Fund to earn a higher level of current income than it
would earn from holding the underlying securities alone. Moreover, the premium
received will offset a portion of the potential loss incurred by the Fund if the
securities underlying the option decline in value.

The Fund may be required, at any time during the option period, to deliver
the underlying security against payment of the exercise price on any calls it
has written. This obligation is terminated upon the expiration of the option
period or at such earlier time when the writer effects a closing purchase
transaction. A closing purchase transaction 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.

Options written by the Fund normally have expiration dates of from up to
eighteen months from the date written. The exercise price of a call option may
be below, equal to or above the current market value of the underlying security
at the time the option is written.

COVERED PUT WRITING. As a writer of a covered put option, the Fund incurs
an obligation to buy the security underlying the option from the purchaser of
the put, at the option's exercise price at any time during the option period, at
the purchaser's election. Through the writing of a put option, the Fund would
receive income from the premium paid by purchasers. The potential gain on a
covered put option is limited to the premium received on the option (less the
commissions paid on the transaction). During the

4
<PAGE>
option period, the Fund may be required, at any time, to make payment of the
exercise price against delivery of the underlying security. The operation of and
limitations on covered put options in other respects are substantially identical
to those of call options.

PURCHASING CALL AND PUT OPTIONS. The Fund may purchase listed and OTC call
and put options in amounts equaling up to 5% of its total assets. The purchase
of a call option would enable the Fund, in return for the premium paid to lock
in a purchase price for a security or currency during the term of the option.
The purchase of a put option would enable the Fund, in return for a premium
paid, to lock in a price at which it may sell a security or currency during the
term of the option.

OTC OPTIONS. OTC options are purchased from or sold (written) to dealers or
financial institutions which have entered into direct agreements with the Fund.
With OTC options, such variables as expiration date, exercise price and premium
will be agreed upon between the Fund and the transacting dealer, without the
intermediation of a third party such as the OCC. The Fund will engage in OTC
option transactions only with member banks of the Federal Reserve Bank System or
primary dealers in U.S. Government securities or with affiliates of such banks
or dealers.

RISKS OF OPTIONS TRANSACTIONS. The successful use of options depends on the
ability of the Investment Manager to forecast correctly interest rates and/or
market movements. If the market value of the portfolio securities upon which
call options have been written increases, the Fund may receive a lower total
return from the portion of its portfolio upon which calls have been written than
it would have had such calls not been written. During the option period, the
covered call writer has, in return for the premium on the option, given up the
opportunity for capital appreciation above the exercise price should the market
price of the underlying security increase, but has retained the risk of loss
should the price of the underlying security decline. The covered put writer also
retains the risk of loss should the market value of the underlying security
decline below the exercise price of the option less the premium received on the
sale of the option. In both cases, the writer has no control over the time when
it may be required to fulfill its obligation as a writer of the option. Prior to
exercise or expiration, an option position can only be terminated by entering
into a closing purchase or sale transaction. Once an option writer has received
an exercise notice, it cannot effect a closing purchase transaction in order to
terminate its obligation under the option and must deliver or receive the
underlying securities at the exercise price.

The Fund's ability to close out its position as a writer of an option is
dependent upon the existence of a liquid secondary market on option exchanges.
There is no assurance that such a market will exist, particularly in the case of
OTC options.

In the event of the bankruptcy of a broker through which the Fund engages in
transactions in options, the Fund could experience delays and/or losses in
liquidating open positions purchased or sold through the broker and/or incur a
loss of all or part of its margin deposits with the broker. In the case of OTC
options, if the transacting dealer fails to make or take delivery of the
securities underlying an option it has written, in accordance with the terms of
that option, due to insolvency or otherwise, the Fund would lose the premium
paid for the option as well as any anticipated benefit of the transaction.

Each of the exchanges has established limitations governing the maximum
number of call or put options on the same underlying security which may be
written by a single investor, whether acting alone or in concert with others
(regardless of whether such options are written on the same or different
exchanges or are held or written on one or more accounts or through one or more
brokers). An exchange may order the liquidation of positions found to be in
violation of these limits and it may impose other sanctions or restrictions.
These position limits may restrict the number of listed options which the Fund
may write.

The hours of trading for options may not conform to the hours during which
the underlying securities are traded. To the extent that the option markets
close before the markets for the underlying securities, significant price and
rate movements can take place in the underlying markets that cannot be reflected
in the option markets.

5
<PAGE>
The value of a foreign currency option depends upon the value of the
underlying currency relative to the U.S. dollar. As a result, the price of the
option position may vary with changes in the value of either or both currencies
and have no relationship to the investment merits of a foreign security. Because
foreign currency transactions occurring in the interbank market involve
substantially larger amounts than those that may be involved in the use of
foreign currency options, investors may be disadvantaged by having to deal in an
odd lot market (generally consisting of transactions of less than $1 million)
for the underlying foreign currencies at prices that are less favorable than for
round lots.

There is no systematic reporting of last sale information for foreign
currencies or any regulatory requirement that quotations available through
dealers or other market sources be firm or revised on a timely basis. Quotation
information available is generally representative of very large transactions in
the interbank market and thus may not reflect relatively smaller transactions
(i.e., less than $1 million) where rates may be less favorable. The interbank
market in foreign currencies is a global, around-the-clock market. To the extent
that the U.S. options markets are closed while the markets for the underlying
currencies remain open, significant price and rate movements may take place in
the underlying markets that are not reflected in the options market.

STOCK INDEX OPTIONS. The Fund may invest in options on broadly based
indexes. Options on stock indexes are similar to options on stock except that,
rather than the right to take or make delivery of stock at a specified price, an
option on a stock index gives the holder the right to receive, upon exercise of
the option, an amount of cash if the closing level of the stock index upon which
the option is based is greater than, in the case of a call, or less than, in the
case of a put, the exercise price of the option. This amount of cash is equal to
such difference between the closing price of the index and the exercise price of
the option expressed in dollars times a specified multiple. The writer of the
option is obligated, in return for the premium received, to make delivery of
this amount.

RISKS OF OPTIONS ON INDEXES. Because exercises of stock index options are
settled in cash, the Fund could not, if it wrote a call option, provide in
advance for its potential settlement obligations by acquiring and holding the
underlying securities. A call writer can offset some of the risk of its writing
position by holding a diversified portfolio of stocks similar to those on which
the underlying index is based. However, most investors cannot, as a practical
matter, acquire and hold a portfolio containing exactly the same stocks as the
underlying index, and, as a result, bear a risk that the value of the securities
held will vary from the value of the index. Even if an index call writer could
assemble a stock portfolio that exactly reproduced the composition of the
underlying index, the writer still would not be fully covered from a risk
standpoint because of the "timing risk" inherent in writing index options.

When an index option is exercised, the amount of cash that the holder is
entitled to receive is determined by the difference between the exercise price
and the closing index level on the date when the option is exercised. As with
other kinds of options, the writer will not learn that it had been assigned
until the next business day, at the earliest. The time lag between exercise and
notice of assignment poses no risk for the writer of a covered call on a
specific underlying security, such as a common stock, because there the writer's
obligation is to deliver the underlying security, not to pay its value as of a
fixed time in the past. So long as the writer already owns the underlying
security, it can satisfy its settlement obligations by simply delivering it, and
the risk that its value may have declined since the exercise date is borne by
the exercising holder. In contrast, even if the writer of an index call holds
stocks that exactly match the composition of the underlying index, it will not
be able to satisfy its assignment obligations by delivering those stocks against
payment of the exercise price. Instead, it will be required to pay cash in an
amount based on the closing index value on the exercise date; and by the time it
learns that it has been assigned, the index may have declined, with a
corresponding decrease in the value of its stock portfolio. This "timing risk"
is an inherent limitation on the ability of index call writers to cover their
risk exposure by holding stock positions.

A holder of an index option who exercises it before the closing index value
for that day is available runs the risk that the level of the underlying index
may subsequently change. If a change causes the

6
<PAGE>
exercised option to fall out-of-the-money, the exercising holder will be
required to pay the difference between the closing index value and the exercise
price of the option (times the applicable multiplier) to the assigned writer.

If dissemination of the current level of an underlying index is interrupted,
or if trading is interrupted in stocks accounting for a substantial portion of
the value of an index, the trading of options on that index will ordinarily be
halted. If the trading of options on an underlying index is halted, an exchange
may impose restrictions prohibiting the exercise of such options.

FUTURES CONTRACTS. The Fund may purchase and sell interest rate and index
futures contracts that are traded on U.S. and foreign commodity exchanges on
such underlying securities as U.S. Treasury bonds, notes, bills and GNMA
Certificates and/or any foreign government fixed-income security, and on such
indexes of U.S. and foreign securities as may exist or come into existence.

A futures contract purchaser incurs an obligation to take delivery of a
specified amount of the obligation underlying the contract at a specified time
in the future for a specified price. A seller of a futures contract incurs an
obligation to deliver the specified amount of the underlying obligation at a
specified time in return for an agreed upon price. The purchase of a futures
contract enables the Fund, during the term of the contract, to lock in a price
at which it may purchase a security and protect against a rise in prices pending
purchase of portfolio securities. The sale of a futures contract enables the
Fund to lock in a price at which it may sell a security and protect against
declines in the value of portfolio securities.

Although most futures contracts call for actual delivery or acceptance of
securities, the contracts usually are closed out before the settlement date
without the making or taking of delivery. Index futures contracts provide for
the delivery of an amount of cash equal to a specified dollar amount times the
difference between the index value at the open or close of the last trading day
of the contract and the futures contract price. A futures contract sale is
closed out by effecting a futures contract purchase for the same aggregate
amount of the specific type of security and the same delivery date. If the sale
price exceeds the offsetting purchase price, the seller would be paid the
difference and would realize a gain. If the offsetting purchase price exceeds
the sale price, the seller would pay the difference and would realize a loss.
Similarly, a futures contract purchase is closed out by effecting a futures
contract sale for the same aggregate amount of the specific type of security and
the same delivery date. If the offsetting sale price exceeds the purchase price,
the purchaser would realize a gain, whereas if the purchase price exceeds the
offsetting sale price, the purchaser would realize a loss. There is no assurance
that the Fund will be able to enter into a closing transaction.

MARGIN. If the Fund enters into a futures contract, it is initially
required to deposit an "initial margin" of cash or U.S. Government securities or
other liquid portfolio securities ranging from approximately 2% to 5% of the
contract amount. Initial margin requirements are established by the exchanges on
which futures contracts trade and may, from time to time, change. In addition,
brokers may establish margin deposit requirements in excess of those required by
the exchanges.

Initial margin in futures transactions is different from margin in
securities transactions in that initial margin does not involve the borrowing of
funds by a broker's client but is, rather, a good faith deposit on the futures
contract which will be returned to the Fund upon the proper termination of the
futures contract. The margin deposits made are marked to market daily and the
Fund may be required to make subsequent deposits of cash or U.S. Government
securities, called "variation margin," which are reflective of price
fluctuations in the futures contract.

OPTIONS ON FUTURES CONTRACTS. The Fund may purchase and write call and put
options on futures contracts and enter into closing transactions with respect to
such options to terminate an existing position. An option on a futures contract
gives the purchaser the right (in return for the premium paid), and the writer
the obligation, to assume a position in a futures contract (a long position if
the option is a call and a short position if the option is a put) at a specified
exercise price at any time during the term of the option. Upon exercise of the
option, the delivery of the futures position by the writer of the option to the
holder of the option is accompanied by delivery of the accumulated balance in
the writer's futures

7
<PAGE>
margin account, which represents the amount by which the market price of the
futures contract at the time of exercise exceeds, in the case of a call, or is
less than, in the case of a put, the exercise price of the option on the futures
contract.

The writer of an option on a futures contract is required to deposit initial
and variation margin pursuant to requirements similar to those applicable to
futures contracts. Premiums received from the writing of an option on a futures
contract are included in initial margin deposits.

LIMITATIONS ON FUTURES CONTRACTS AND OPTIONS ON FUTURES. The Fund may not
enter into futures contracts or purchase related options thereon if, immediately
thereafter, the amount committed to margin plus the amount paid for premiums for
unexpired options on futures contracts exceeds 5% of the value of the Fund's
total assets, after taking into account unrealized gains and unrealized losses
on such contracts it has entered into, provided, however, that in the case of an
option that is in-the-money (the exercise price of the call (put) option is less
(more) than the market price of the underlying security) at the time of
purchase, the in-the-money amount may be excluded in calculating the 5%.
However, there is no overall limitation on the percentage of the Fund's net
assets which may be subject to a hedge position.

RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS. The prices
of securities and indexes subject to futures contracts (and thereby the futures
contract prices) may correlate imperfectly with the behavior of the cash prices
of the Fund's portfolio securities. Also, prices of futures contracts may not
move in tandem with the changes in prevailing interest rates and/or market
movements against which the Fund seeks a hedge. A correlation may also be
distorted (a) temporarily, by short-term traders' seeking to profit from the
difference between a contract or security price objective and their cost of
borrowed funds; (b) by investors in futures contracts electing to close out
their contracts through offsetting transactions rather than meet margin deposit
requirements; (c) by investors in futures contracts opting to make or take
delivery of underlying securities rather than engage in closing transactions,
thereby reducing liquidity of the futures market; and (d) temporarily, by
speculators who view the deposit requirements in the futures markets as less
onerous than margin requirements in the cash market. Due to the possibility of
price distortion in the futures market and because of the possible imperfect
correlation between movements in the prices of securities and movements in the
prices of futures contracts, a correct forecast of interest rate, currency
exchange rate and/or market movement trends by the Investment Manager may still
not result in a successful hedging transaction.

There is no assurance that a liquid secondary market will exist for futures
contracts and related options in which the Fund may invest. In the event a
liquid market does not exist, it may not be possible to close out a futures
position and, in the event of adverse price movements, the Fund would continue
to be required to make daily cash payments of variation margin. In addition,
limitations imposed by an exchange or board of trade on which futures contracts
are traded may compel or prevent the Fund from closing out a contract which may
result in reduced gain or increased loss to the Fund. The absence of a liquid
market in futures contracts might cause the Fund to make or take delivery of the
underlying securities at a time when it may be disadvantageous to do so.

Exchanges limit the amount by which the price of a futures contract may move
on any day. If the price moves equal the daily limit on successive days, then it
may prove impossible to liquidate a futures position until the daily limit moves
have ceased. In the event of adverse price movements, the Fund would continue to
be required to make daily cash payments of variation margin on open futures
positions. In these situations, if the Fund has insufficient cash, it may have
to sell portfolio securities to meet daily variation margin requirements at a
time when it may be disadvantageous to do so. In addition, the Fund may be
required to take or make delivery of the instruments underlying interest rate
futures contracts it holds at a time when it is disadvantageous to do so. The
inability to close out options and futures positions could also have an adverse
impact on the Fund's ability to effectively hedge its portfolio.

Futures contracts and options thereon which are purchased or sold on foreign
commodities exchanges may have greater price volatility than their U.S.
counterparts. Furthermore, foreign commodities exchanges may be less regulated
and under less governmental scrutiny than U.S. exchanges.

8
<PAGE>
Brokerage commissions, clearing costs and other transaction costs may be higher
on foreign exchanges. Greater margin requirements may limit the Fund's ability
to enter into certain commodity transactions on foreign exchanges. Moreover,
differences in clearance and delivery requirements on foreign exchanges may
occasion delays in the settlement of the Fund's transactions effected on foreign
exchanges.

In the event of the bankruptcy of a broker through which the Fund engages in
transactions in futures or options thereon, the Fund could experience delays
and/or losses in liquidating open positions purchased or sold through the broker
and/or incur a loss of all or part of its margin deposits with the broker.

MONEY MARKET SECURITIES. In addition to the short-term fixed-income
securities in which the Fund may otherwise invest, the Fund may invest in
various money market securities for cash management purposes or when assuming a
temporary defensive position, which among others may include commercial paper,
bank acceptances, bank obligations, corporate debt securities certificates of
deposit, U.S. Government securities and obligations of savings institutions.
Such securities are limited to:

U.S. GOVERNMENT SECURITIES. Obligations issued or guaranteed as to
principal and interest by the United States or its agencies (such as the
Export-Import Bank of the United States, Federal Housing Administration and
Government National Mortgage Association) or its instrumentalities (such as the
Federal Home Loan Bank), including Treasury bills, notes and bonds;

BANK OBLIGATIONS. Obligations (including certificates of deposit, time
deposits and bankers' acceptances) of banks subject to regulation by the U.S.
Government and having total assets of $1 billion or more, and instruments
secured by such obligations, not including obligations of foreign branches of
domestic banks except to the extent below;

EURODOLLAR CERTIFICATES OF DEPOSIT. Eurodollar certificates of deposit
issued by foreign branches of domestic banks having total assets of $1 billion
or more;

OBLIGATIONS OF SAVINGS INSTITUTIONS. Certificates of deposit of savings
banks and savings and loan associations, having total assets of $1 billion or
more;

FULLY INSURED CERTIFICATES OF DEPOSIT. Certificates of deposit of banks and
savings institutions, having total assets of less than $1 billion. If the
principal amount of the obligation is federally insured by the Bank Insurance
Fund or the Savings Association Insurance Fund (each of which is administered by
the FDIC), limited to $100,000 principal amount per certificate and to 10% or
less of the Fund's total assets in all such obligations and in all illiquid
assets, in the aggregate;

COMMERCIAL PAPER. Commercial paper rated within the two highest grades by
Standard & Poor's Corporation ("S&P") or the two highest grades by Moody's
Investors Service, Inc. ("Moody's") or, if not rated, issued by a company having
an outstanding debt issue rated at least AA by S&P or Aa by Moody's; and

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 from
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.

9
<PAGE>
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 from 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 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 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. 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

10
<PAGE>
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 assets committed to the purchase of securities on a
"when, as and if issued" basis may increase the volatility of its net asset
value. The 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.

PRIVATE PLACEMENTS. The Fund may invest up to 10% of its total assets in
securities which are subject to restrictions on resale because they have not
been registered under the Securities Act of 1933 (the "SECURITIES ACT"), or
which are otherwise not readily marketable. (Securities eligible for resale
pursuant to Rule 144A under the Securities Act, and determined to be liquid
pursuant to the procedures discussed in the following paragraph, are not subject
to the foregoing restriction.) These securities are generally referred to as
private placements or restricted securities. Limitations on the resale of these
securities may have an adverse effect on their marketability, and may prevent
the Fund from disposing of them promptly at reasonable prices. The Fund may have
to bear the expense of registering the securities for resale and the risk of
substantial delays in effecting the registration.

Rule 144A permits the Fund to sell restricted securities to qualified
institutional buyers without limitation. The Investment Manager, pursuant to
procedures adopted by the Trustees, will make a determination as to the
liquidity of each restricted security purchased by the Fund. If a restricted
security is determined to be "liquid," the security will not be included within
the category "illiquid securities," which is limited by the Fund's investment
restrictions to 10% of the Fund's net assets.

WARRANTS AND SUBSCRIPTION RIGHTS. The Fund may acquire warrants and
subscription rights attached to other securities. A warrant is, in effect, an
option to purchase equity securities at a specific price, generally valid for a
specific period of time, and has no voting rights, pays no dividends and has no
rights with respect to the corporation issuing it.

A subscription right is a privilege granted to existing shareholders of a
corporation to subscribe to shares of a new issue of common stock before it is
offered to the public. A subscription right normally has a life of two to four
weeks and a subscription price lower than the current market value of the common
stock. A subscription right is freely transferable.

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS. The Fund may enter into
forward U.S. dollar and foreign currency exchange contracts ("FORWARD
CONTRACTS") as a hedge against fluctuations in future foreign exchange rates.
The Fund may conduct its currency exchange transactions either on a spot (i.e.,
cash) basis at the spot rate prevailing in the foreign currency exchange market,
or through entering into forward contracts to purchase or sell foreign
currencies. A forward contract involves an obligation to purchase or sell a
specific currency at a future date, which may be any fixed number of days from
the date of the contract agreed upon by the parties, at a price set at the time
of the contract. These contracts are traded in the interbank market conducted
directly between currency traders (usually large, commercial and investment
banks) and their customers. Forward contracts only will be entered into with
United States banks and their foreign branches, insurance companies and other
dealers whose assets total $1 billion or more, or foreign banks whose assets
total $1 billion or more. A forward contract generally has no deposit
requirement, and no commissions are charged at any stage for trades.

The Fund may enter into forward contracts under various circumstances. The
typical use of a forward contract is to "lock in" the price of a security in
U.S. dollars or some other foreign currency which the Fund is holding in its
portfolio. By entering into a forward contract for the purchase or sale, for a
fixed

11
<PAGE>
amount of dollars or other currency, of the amount of foreign currency involved
in the underlying security transactions, the Fund may be able to protect itself
against a possible loss resulting from an adverse change in the relationship
between the U.S. dollar or other currency which is being used for the security
purchase and the foreign currency in which the security is denominated during
the period between the date on which the security is purchased or sold and the
date on which payment is made or received.

The Investment Manager also may from time to time utilize forward contracts
for other purposes. For example, they may be used to hedge a foreign security
held in the portfolio or a security which pays out principal tied to an exchange
rate between the U.S. dollar and a foreign currency, against a decline in value
of the applicable foreign currency. They also may be used to lock in the current
exchange rate of the currency in which those securities anticipated to be
purchased are denominated. At times, the Fund may enter into "cross-currency"
hedging transactions involving currencies other than those in which securities
are held or proposed to be purchased are denominated.

The Fund will not enter into forward currency contracts or maintain a net
exposure to these contracts where the consummation of the contracts would
obligate the Fund to deliver an amount of currency in excess of the value of the
Fund's portfolio securities.

Although the Fund values its assets daily in terms of U.S. dollars, it does
not intend to convert its holdings of foreign currencies into U.S. dollars on a
daily basis. It will, however, do so from time to time, and investors should be
aware of the costs of currency conversion. Although foreign exchange dealers do
not charge a fee for conversion, they do realize a profit based on the spread
between the prices at which they are buying and selling various currencies.
Thus, a dealer may offer to sell a foreign currency to the Fund at one rate,
while offering a lesser rate of exchange should the Fund desire to resell that
currency to the dealer.

The Fund may be limited in its ability to enter into hedging transactions
involving forward contracts by the Internal Revenue Code requirements relating
to qualification as a regulated investment company.

Forward currency contracts may limit gains on portfolio securities that
could otherwise be realized had they not been utilized and could result in
losses. The contracts also may increase the Fund's volatility and may involve a
significant amount of risk relative to the investment of cash.

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.
Corporate and governmental data processing errors also 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.

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

12
<PAGE>
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. For purposes of the following
restrictions: (i) all percentage limitations apply immediately after a purchase
or initial investment; and (ii) any subsequent change in any applicable
percentage resulting from market fluctuations or other changes in total or net
assets does not require elimination of any security from the portfolio.

The Fund will:

1. Seek to provide current income and long-term growth of income and
capital.
The Fund MAY NOT:

1. Invest more than 5% of the value of its total assets in the securities
of any one issuer (other than obligations issued, or guaranteed by, the United
States Government, its agencies or instrumentalities).

2. Purchase more than 10% of the voting securities, or more than 10% of any
class of securities, of any one issuer.

3. Invest 25% or more of the value of its total assets in securities of
issuers in any one industry, except that the Fund will concentrate in the public
utilities industry. The restriction does not apply to obligations issued or
guaranteed by the United States Government, its agencies or instrumentalities.

On April 22, 1999, the Board of Trustees unanimously recommended that
the Fund's shareholders approve (at their meeting scheduled for August 4, 1999)
eliminating the word "public" from this restriction. This change would require
the Fund to concentrate investments in the entire utilities industry, as opposed
to the more limited "public" utilities industry.

4. Purchase securities of other investment companies, except in connection
with a merger, consolidation, reorganization or acquisition of assets.

5. Invest more than 5% of the value of its total assets in securities of
issuers having a record, together with predecessors, of less than 3 years of
continuous operation. This restriction shall not apply to any obligation issued
or guaranteed by the United States Government, its agencies or
instrumentalities.

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 that 1/2
of 1% of the outstanding securities of such issuer, and such officers and
Trustees who own more than 1/2 of 1% own in the aggregate more than 5% of the
outstanding securities of such issuers.

7. Purchase or sell real estate or interests therein (including limited
partnership interests), although the Fund may purchase securities of issuers
which engage in real estate operations and securities secured by real estate or
interests therein.

8. Purchase oil, gas or other mineral leases, rights or royalty contracts
or exploration or development programs, except that the Fund may invest in the
securities of companies which operate, invest in, or sponsor these programs.

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 its total assets (not including the amount borrowed).

10. Pledge its assets or assign or otherwise encumber them except to secure
permitted borrowings. For the purpose of this restriction, collateral
arrangements with respect to the writing of options and collateral arrangements
with respect to initial or variation margin for futures are not deemed to be
pledges of assets.

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 reason of
borrowing money.

13
<PAGE>
12. Make loans of money or securities, except: (a) by the purchase of
publicly distributed debt obligations; (b) by investment in repurchase
agreements; or (c) by lending its portfolio securities.

13. Make short sales of securities.

14. Purchase securities on margin, except for short-term loans as are
necessary for the clearance of portfolio securities. The deposit or payment by
the Fund of initial or variation margin in connection with futures contracts or
related options thereon is not considered the purchase of a security on margin.

15. Engage in the underwriting of securities, except insofar as the Fund may
be deemed an underwriter under the Securities Act in disposing of a portfolio
security.

16. Invest for the purpose of exercising control or management of any other
issuer.

17. Invest more than 10% of its total assets in "illiquid securities"
(securities for which market quotations are not readily available) and
repurchase agreements which have a maturity of longer than seven days.

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

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.

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 eight (8)
Trustees. These same individuals also serve as directors or trustees for all of
the Morgan Stanley Dean Witter Funds. Six Trustees (75% 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. Three of the
six 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.

INDEPENDENT DIRECTORS/TRUSTEES AND THE COMMITTEES. Law and regulation
establish both general guidelines and specific duties for the independent
directors/trustees. The Morgan Stanley Dean Witter Funds seek as independent
directors/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.
All of the independent directors/trustees serve as members of the Audit
Committee. In addition, three of the directors/trustees, including two
independent directors/trustees, serve as members of the Derivatives Committee
and the Insurance Committee.

The independent directors/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 directors/trustees are required to select and nominate individuals
to fill any independent directors 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.

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 DIRECTORS/TRUSTEES FOR
ALL MORGAN STANLEY DEAN WITTER FUNDS. The independent directors/trustees and
the Funds' management believe that having the same independent
directors/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 directors/trustees for each of the Funds or
even of sub-groups of Funds. They believe that having the same individuals serve
as independent directors/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 directors/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
directors/trustees serve on all Fund Boards

18
<PAGE>
enhances the ability of each Fund to obtain, at modest cost to each separate
Fund, the services of independent directors/trustees, of the caliber, experience
and business acumen of the individuals who serve as independent
directors/trustees of the Morgan Stanley Dean Witter Funds.

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
and the Chairmen of the Derivatives and Insurance Committees additional annual
fees of $500). 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 expense
reimbursement from the Fund for their services as Trustee.

The following table illustrates the compensation that the Fund paid to its
Independent Trustees for the fiscal 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 director/ 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/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 director/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 29.41% 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 58.82% after ten years of service. The foregoing percentages may
be changed by the Board.(1) "ELIGIBLE COMPENSATION" is one-fifth of the total
compensation earned by such Eligible Trustee for service to the Adopting Fund in
the five year period prior to the date of the Eligible Trustee's retirement.
Benefits under the retirement program are not secured or funded by the Adopting
Funds.
The following table illustrates the retirement benefits accrued to the
Fund's Independent Trustees by the Fund for the fiscal year ended December 31,
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 55 Morgan

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

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, manage its business affairs and supervise the
investment of the Fund's assets. 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: As full
compensation for the services and facilities furnished to the Fund and expenses
of the Fund assumed by the Investment Manager, the Fund pays the Investment
Manager monthly compensation calculated daily by applying the following annual
rates to the daily net assets of the Fund: 0.65% of the portion of the daily net
assets not exceeding $500 million, 0.55% of the portion of the daily net assets
exceeding $500 million but not exceeding $1 billion; 0.525% of the portion of
the daily net assets exceeding $1 billion but not exceeding $1.5 billion; 0.50%
of the portion of the daily net assets exceeding $1.5 billion but not exceeding

but not exceeding $3.5 billion; 0.45% of the portion of the daily net assets
exceeding $3.5 billion but not exceeding $5 billion; and 0.425% of the portion
of the net assets exceeding $5 billion. The management fee is allocated among
the Classes pro rata based on the net assets of the Fund attributable to each
Class. The Fund accrued total compensation to the Investment Manager of
$15,787,095, $13,037,906 and $13,749,432, during the fiscal years ended December
31, 1996, 1997 and 1998, 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

21
<PAGE>
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 supervises the investment of the Fund's assets. 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 oversee the management of the assets of the
Fund in a manner consistent with its investment objectives.

Under the terms of the Management Agreement, the Investment Manager also
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
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

22
<PAGE>
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 who are not parties to the Management Agreement or are "Independent
Trustees," which votes must be cast in person at a meeting called for the
purpose of voting on such approval.

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 1.0% of the average daily net assets of
Class A and Class C, respectively, and, with respect to Class B, 1.0% of the
lesser of: (a) the average daily aggregate gross sales of the Fund's Class B
shares since the inception of the Fund (not including 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 Fund's 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 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 0.25% of such Class' average daily net assets are
currently each characterized as a "service fee" under the Rules of the

23
<PAGE>
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 $24,988,369. This amount is equal to 1.00% of the average daily net
assets of Class B and was calculated pursuant to clause (a) of the compensation
formula under the Plan. For the fiscal year ended December 31, 1998, Class A and
Class C shares of the Fund accrued payments under the Plan amounting to $14,369
and $33,092, respectively, which amounts are equal to 0.25% and 1.00% 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 5.0% of the
amount sold (except as provided in the following sentence) and an annual
residual commission, currently a residual of up to 0.25% of the current value of
the respective accounts for which they are the Financial Advisors or dealers of
record in all cases. On orders of $1 million or more (for which no sales charge
was paid) or net asset value purchases by employer-sponsored employee benefit
plans, whether or not qualified under the Internal Revenue Code, for which the
Transfer Agent serves as Trustee or Dean Witter Reynolds Retirement Plan
Services serves as recordkeeper pursuant to a written Recordkeeping Services
Agreement ("MSDW ELIGIBLE PLANS"), 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 5.0% of the amount
sold (except as provided in the following sentence) and an annual residual
commission, currently a residual of up to 0.25% of the current value (not
including reinvested dividends or distributions) of the amount sold in all
cases. In the case of Class B shares purchased by MSDW Eligible Plans, Dean
Witter Reynolds compensates its Financial Advisors by paying them, from its own
funds, a gross sales credit of 3.0% of the amount sold.

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 1.0% of the current
value of the respective accounts for which they are the Financial Advisors of
record.

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).

24
<PAGE>
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 1.0%, in the case of Class C, of the average net assets of the respective
Class during the month. No interest or other financing charges, if any, incurred
on any distribution expenses on behalf of Class A and Class C will be
reimbursable under the Plan. With respect to Class A, in the case of all
expenses other than expenses representing the service fee, and, with respect to
Class C, in the case of all expenses other than expenses representing a gross
sales credit or a residual to 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, $324,078,035 on behalf of Class B since the inception of the Fund. It
is estimated that this amount was spent in approximately the following ways: (i)
1.56% ($5,051,698)--advertising and promotional expenses; (ii) 0.16%
($505,149)--printing of prospectuses for distribution to other than current
shareholders; and (iii) 98.28% ($318,521,188)--other expenses, including the
gross sales credit and the carrying charge, of which 11.19% ($35,650,403)
represents carrying charges, 36.32% ($115,694,151) represents commission credits
to Dean Witter Reynolds branch offices and other selected broker-dealers for
payments of commissions to Financial Advisors and other selected broker-dealer
representatives, and 52.49% ($167,176,634) 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.

25
<PAGE>
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 $53,504,895 as of December 31, 1998 (the end of
the Fund's fiscal year), which was equal to 1.9% 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 1.0% of the average daily net
assets of Class A or Class C, respectively, will not be reimbursed by the Fund
through payments in any subsequent year, except that expenses representing a
gross sales commission credited to Morgan Stanley Dean Witter Financial Advisors
and other authorized broker-dealer 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 broker-dealer
representatives at the time of sale totaled $13,403 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
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,

26
<PAGE>
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 non-affiliated dealers acting as principal for their own
accounts without a stated commission, although the price of the security usually
includes a profit to the dealer. 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.

27
<PAGE>
For the fiscal years ended December 31, 1996, 1997 and 1998, the Fund paid a
total of $522,394, $834,417 and $476,585, respectively, in 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.

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.

During the fiscal years ended December 31, 1996, 1997 and 1998, the Fund
paid a total of $162,125, $279,015 and $79,500, respectively, in brokerage
commissions to Dean Witter Reynolds. During the fiscal year ended December 31,
1998, the brokerage commissions paid to Dean Witter Reynolds represented
approximately 17% of the total brokerage commissions paid by the Fund during the
year and were paid on account of transactions having an aggregate dollar value
equal to approximately 21% of the aggregate dollar value of all portfolio
transactions of the Fund during the year for which commissions were paid.

During the period June 1 through December 31, 1997 and during the fiscal
year ended December 31, 1998, the Fund paid a total of $2,000 and $3,250,
respectively, in brokerage commissions to Morgan Stanley & Co., which
broker-dealer became an affiliate of the Investment Manager on May 31, 1997 upon
consummation of the merger of Dean Witter, Discover & Co. with Morgan Stanley
Group Inc. During the fiscal year ended December 31, 1998, the brokerage
commissions paid to Morgan Stanley & Co. represented approximately 1% of the
total brokerage commissions paid by the Fund for this period and were paid on
account of transactions having an aggregate dollar value equal to approximately
1% of the aggregate dollar value of all portfolio transactions of the Fund
during the year for which commissions were paid.

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

28
<PAGE>
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 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 serve as advisors 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 paid $381,585 in
brokerage commissions in connection with transactions in the aggregate amount of
$240,309,703 to brokers because of research services provided.

E. REGULAR BROKER-DEALERS

During the fiscal year ended December 31, 1998, the Fund has not purchased
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.

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.

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

29
<PAGE>
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 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.

30
<PAGE>
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 Fund shares, called "NET ASSET VALUE," is based on the value of
the Fund's portfolio securities. Net asset value per share of each Class is
calculated by dividing the value of the portion of the Fund's securities and
other assets attributable to that Class, less the liabilities attributable to
that Class, by the number of shares of that Class outstanding. The assets of
each Class of shares are invested in a single portfolio. The net asset value of
each Class, however, will differ because the Classes have different ongoing
fees.

In the calculation of the Fund's net asset value: (1) an equity portfolio
security listed or traded on the New York or American Stock Exchange or other
stock exchange is valued at its latest sale price on that exchange, prior to the
time when assets are valued; if there were no sales that day, the security is
valued at the latest bid price (in cases where a security is traded on more than
one exchange, the security is valued on the exchange designated as the primary
market pursuant to procedures adopted by the Trustees); and (2) all other
portfolio securities for which over-the-counter market quotations are readily
available are valued at the latest bid price. When market quotations are not
readily available, including circumstances under which it is determined by the
Investment Manager that sale or bid prices are not reflective of a security's
market value, portfolio securities are valued at their fair value as determined
in good faith under procedures established by and under the general supervision
of the Fund's Trustees. For valuation purposes, quotations of foreign portfolio
securities, other assets and liabilities and forward contracts stated in foreign
currency are translated into U.S. dollar equivalents at the prevailing market
rates prior to the close of the New York Stock Exchange.

Short-term debt securities with remaining maturities of sixty days or less
at the time of purchase are valued at amortized cost, unless the Trustees
determine such does not reflect the securities' market value, in which case
these securities will be valued at their fair value as determined by the
Directors.

Certain of the Fund's portfolio securities may be valued by an outside
pricing service approved by the Fund's Trustees. The pricing service may utilize
a matrix system incorporating security quality, maturity and coupon as the
evaluation model parameters, and/or research evaluations by its staff, including
review of broker-dealer market price quotations in determining what it believes
is the fair valuation of the portfolio securities valued by such pricing
service.

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
latest bid and asked prices. Unlisted options on debt securities and all options
on equity securities are valued at the mean between their latest bid and asked
prices. Futures are valued at the latest sale price on the commodities exchange
on which they trade unless the Trustees determine such price does not reflect
their market value, in which case they will be valued at their fair value as
determined in good faith under procedures established by and under the
supervision of the Trustees.

Generally, trading in foreign securities, as well as corporate bonds, U.S.
Government securities and money market instruments, is substantially completed
each day at various times prior to the close of the New York Stock Exchange. The
values of such securities used in computing the net asset value of the Fund's
shares are determined as of such times. Foreign currency exchange rates are also
generally determined prior to the close of the New York Stock Exchange.
Occasionally, events which may affect the values of such securities and such
exchange rates may occur between the times at which they are determined and the
close of the New York Stock Exchange and will therefore not be reflected in the
computation of the Fund's net asset value. If events that may affect the value
of such securities occur during such period, then these securities may be 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 two basic types of distributions: ordinary
dividends and long-term capital gain distributions. These two 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. Tax issues relating to the Fund
are not generally a consideration for shareholders such as tax exempt entities
and tax-advantaged retirement vehicles such as an IRA or 401(k) plan.
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.

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 net long-term 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.

Gains or losses on the Fund's transactions in listed non-equity options,
futures and options on futures generally are treated as 60% long-term and 40%
short-term. When the Fund engages in options and futures transactions, various
tax rules may accelerate or defer recognition of certain gains and losses,
change the character of certain gains or losses, or alter the holding period of
other investments held by the Fund. The application of these rules would
therefore also affect the amount, timing and character of distributions made by
the Fund.

Under certain tax rules, the Fund may be required to accrue a portion of any
discount at which certain securities are purchased as income each year even
though the Fund receives no payments in cash on the security during the year. To
the extent that the Fund invests in such securities, it would be required to pay
out such accrued discount as an income distribution in each year in order to
avoid taxation at the Fund level. Such distributions will be made from the
available cash of the Fund or by liquidation of portfolio securities if
necessary. If a distribution of cash necessitates the liquidation of portfolio
securities, the Investment Manager will select which securities to sell. The
Fund may realize a gain or loss from such sales. In the event the Fund realizes
net capital gains from such transactions, its shareholders may receive a larger
capital gain distribution, if any, than they would in the absence of such
transactions.

TAXATION OF DIVIDENDS AND DISTRIBUTIONS. Shareholders normally will have to
pay federal income taxes, and any state and/or local income taxes, on the
dividends and other distributions they receive from the Fund. Such dividends and
distributions, to the extent that they are derived from net investment income or
short-term capital gains, are taxable to the shareholder as ordinary income
regardless of whether the shareholder receives such payments in additional
shares or in cash.

Distributions of net long-term capital gains, if any, are taxable to
shareholders as long-term capital gains regardless of how long a shareholder has
held the Fund's shares and regardless of whether the distribution is received in
additional shares or in cash. The Taxpayer Relief Act of 1997 reduced the
maximum tax on long-term capital gains applicable to individuals from 28% to
20%.

32
<PAGE>
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 investment 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 amount of any dividends eligible for the federal
dividends received deduction for corporations.

PURCHASES AND REDEMPTIONS AND EXCHANGES OF FUND SHARES. Any dividend or
capital gains distribution received by a shareholder from any investment company
will have the effect of reducing the net asset value of the shareholder's stock
in that company by the exact amount of the dividend or capital gains
distribution. Furthermore, such dividends and capital gains distributions are
subject to federal income taxes. If the net asset value of the shares should be
reduced below a shareholder's cost as a result of the payment of dividends or
the distribution of realized 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 Fund shares 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. Fund shares 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.

Exchanges of Fund shares for shares of another fund, including 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 first fund, followed by the purchase of shares in the
second fund.

If a shareholder realizes a loss on the redemption or exchange of a fund's
shares and reinvests in that fund's shares 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.

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."

33
<PAGE>
XI. CALCULATION OF PERFORMANCE DATA
- --------------------------------------------------------------------------------

From time to time, the Fund may quote its "total return" in advertisements
and sales literature. These figures are computed separately for Class A, Class
B, Class C and Class D shares. The Fund's "average annual total return"
represents an annualization of the Fund's total return over a particular period
and is computed by finding the annual percentage rate which will result in the
ending redeemable value of a hypothetical $1,000 investment made at the
beginning of a one, five or ten year period, or for the period from the date of
commencement of 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 16.95%, 13.02% and 12.93%,
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 16.41% and 24.97%, 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 20.92% and 28.79%, 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 23.21% and
30.11%, respectively.

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 21.95%, 13.26% and 12.93%, 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 22.86% and 29.79%,
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 21.92% and 28.79%, 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 23.21% and 30.11%, 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
aggregate total returns for Class B for the one year, five year and ten year
periods ended December 31, 1998, were 21.95%, 86.37 and 237.50%, 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 22.86% and 45.05%,
respectively, and 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 21.92%
and 43.47%, respectively. The aggregate 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 23.21% and 45.56%, 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

34
<PAGE>
multiplying by $9,475, $48,000 and $97,000 in the case of Class A (investments
of $10,000, $50,000 and $100,000 adjusted for the initial sales charge) or by
$10,000, $50,000 and $100,000 in the case of each of Class B, Class C and Class
D, as the case may be. Investments of $10,000, $50,000 and $100,000 in each
Class at inception of the Class would have grown to the following amounts at
December 31, 1998:

certain performance rankings and indexes compiled by recognized organizations.

NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1998

1. ORGANIZATION AND ACCOUNTING POLICIES

Morgan Stanley Dean Witter Utilities Fund (the "Fund"), formerly Dean Witter
Utilities 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 current income and long-term
growth of income and capital. The Fund seeks to achieve its objective by
investing primarily in equity and fixed income securities of companies engaged
in the public utilities industry. The Fund was organized as a Massachusetts
business trust on December 8, 1987 and commenced operations on April 29, 1988.
On July 28, 1997, the Fund commenced offering three additional classes of
shares, with the then current shares, other than shares held by certain employee
benefit plans established by Dean Witter Reynolds Inc. and its affiliate, SPS
Transaction Services, Inc., designated as Class B shares. Shares held by those
employee benefit plans prior to July 28, 1997 have been designated Class D
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 -- (1) an equity security listed or traded on the
New York, American or other domestic or foreign stock exchange is valued at its
latest sale price on that exchange prior to the time when assets are valued; if
there were no sales that day, the security is valued at the latest bid price (in
cases where securities are traded on more than one exchange; the securities are
valued on the exchange designated as the primary market pursuant to the
procedures adopted by the Trustees); (2) all other portfolio securities for
which over-the-counter market quotations are readily available are valued at the
latest available bid price prior to the time of valuation; (3) when market
quotations are not readily available, including circumstances under which it is
determined by Morgan Stanley Dean Witter Advisors, Inc. (the "Investment
Manager"), formerly Dean Witter InterCapital

44
<PAGE>
MORGAN STANLEY DEAN WITTER UTILITIES FUND
NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1998, CONTINUED

Inc., that sale or bid prices are not reflective of a security's market value,
portfolio securities are valued at their fair value as determined in good faith
under procedures established by and under the general supervision of the
Trustees (valuation of debt securities for which market quotations are not
readily available may be based upon current market prices of securities which
are comparable in coupon, rating and maturity or an appropriate matrix utilizing
similar factors); (4) certain of the Fund's portfolio securities may be valued
by an outside pricing service approved by the Trustees. The pricing service may
utilize a matrix system incorporating security quality, maturity and coupon as
the evaluation model parameters, and/or research and evaluations by its staff,
including review of broker-dealer market price quotations, if available, in
determining what it believes is the fair valuation of the portfolio securities
valued by such pricing service; and (5) short-term debt securities having a
maturity date of more than sixty days at time of purchase are valued on a
mark-to-market basis until sixty days prior to maturity and thereafter at
amortized cost based on their value on the 61st day. Short-term debt securities
having a maturity date of sixty days or less at the time of purchase are valued
at amortized cost.

B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Discounts are amortized over the life of the respective securities. Dividend
income and other distributions are recorded on the ex-dividend date. 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 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

45
<PAGE>
MORGAN STANLEY DEAN WITTER UTILITIES FUND
NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1998, CONTINUED

are permanent in nature, such amounts are reclassified within the capital
accounts based on their federal tax-basis treatment; temporary differences do
not require reclassification. Dividends and distributions which exceed net
investment income and net realized capital gains for financial reporting
purposes but not for tax purposes are reported as dividends in excess of net
investment income or distributions in excess of net realized capital gains. To
the extent they exceed net investment income and net realized capital gains for
tax purposes, they are reported as distributions of paid-in-capital.

2. INVESTMENT MANAGEMENT AGREEMENT

Pursuant to an Investment Management Agreement with the Investment Manager, the
Fund pays the Investment Manager a management fee, accrued daily and payable
monthly, by applying the annual rate of 0.65% to the portion of daily net assets
not exceeding $500 million; 0.55% to the portion of daily net assets exceeding
$500 million but not exceeding $1 billion; 0.525% to the portion of daily net
assets exceeding $1 billion but not exceeding $1.5 billion; 0.50% to the portion
of daily net assets exceeding $1.5 billion but not exceeding $2.5 billion;
0.475% to the portion of daily net assets exceeding $2.5 billion but not
exceeding $3.5 billion; 0.45% to the portion of daily net assets exceeding $3.5
billion but not exceeding $5 billion; and 0.425% to the portion of daily net
assets exceeding $5 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 -- 1.0% 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

46
<PAGE>
MORGAN STANLEY DEAN WITTER UTILITIES FUND
NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1998, CONTINUED

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 1.0% 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 such excess amounts, including
carrying charges, totaled $53,504,895 at December 31, 1998.

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 1.0% of the average daily
net assets of Class A or Class C, respectively, will not be reimbursed by the
Fund through payments in any subsequent year, except that expenses representing
a gross sales 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
1.0%, respectively.

47
<PAGE>
MORGAN STANLEY DEAN WITTER UTILITIES FUND
NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1998, CONTINUED

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 A shares, Class B shares and Class C shares of $45, $1,585,359 and
$4,685, respectively and received $55,642 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
$156,377,720 and $374,661,253, respectively. Included in the aforementioned are
purchases and sales of U.S. Government securities of $22,804,464 and
$20,347,391, respectively.

For the year ended December 31, 1998, the Fund incurred $79,500 in brokerage
commissions with DWR for portfolio transactions executed on behalf of the Fund.

For the year ended December 31, 1998, the Fund incurred brokerage commissions of
$3,250 with Morgan Stanley & Co., Inc., an affiliate of the Investment Manager
and Distributor, for portfolio transactions executed on behalf of the Fund.

Morgan Stanley Dean Witter Trust FSB, an affiliate of the Investment Manager and
Distributor, is the Fund's transfer agent. At December 31, 1998, the Fund had
transfer agent fees and expenses payable of approximately $15,000.

The Fund has an unfunded noncontributory defined benefit pension plan covering
all independent Trustees of the Fund who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on years of service and compensation during the last five years
of service. Aggregate pension costs for the year ended December 31, 1998
included in Trustees' fees and expenses in the Statement of Operations amounted
to $6,162. At December 31, 1998, the Fund had an accrued pension liability of
$52,195 which is included in accrued expenses in the Statement of Assets and
Liabilities.

MORGAN STANLEY DEAN WITTER UTILITIES FUND
REPORT OF INDEPENDENT ACCOUNTANTS

TO THE SHAREHOLDERS AND TRUSTEES
OF MORGAN STANLEY DEAN WITTER UTILITIES 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
Utilities Fund (the "Fund"), formerly Dean Witter Utilities 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.
