THE FUND

[GRAPHIC OMITTED]

INVESTMENT OBJECTIVE
- --------------------------------
Morgan Stanley Dean Witter Income Builder Fund seeks reasonable
income as a primary investment objective. As a secondary objective,
the Fund seeks growth of capital.

[GRAPHIC OMITTED]

[sidebar]
GROWTH & INCOME
An investment objective having the goal of selecting securities with the
potential to rise in price and pay out income.
[end sidebar]

PRINCIPAL INVESTMENT STRATEGIES
- --------------------------------------------
The Fund will normally invest at least 65% of its total assets in
income-producing equity securities, including common stock, preferred
stock and convertible securities. The "Investment Manager," Morgan
Stanley Dean Witter Advisors Inc., uses a value-oriented style in the
selection of securities. Investments are normally made primarily in
(i) common stocks of large capitalization companies with a record of
paying dividends and which, in the opinion of the Investment Manager,
have the potential for maintaining dividends, (ii) preferred stock and
(iii) securities convertible into common stocks of small and midcap
companies -- including synthetic and enhanced convertibles. The Fund's
investments also include "Rule 144A" securities, which are subject to
resale restrictions.

The Investment Manager follows a "bottom-up" approach in the
selection of convertible securities for the Fund. Beginning with a
universe of about 500 companies, the Investment Manager narrows the
focus to small and midcap companies and reviews the issues to
determine if the convertible is trading with the underlying equity
security. The yield of the underlying equity security is evaluated
and company fundamentals are studied to evaluate cash flow,
risk/reward balance, valuation and the prospects for growth.

The Fund may invest up to 25% of its total assets in "enhanced"
convertible securities. Enhanced convertible securities offer holders
the opportunity to obtain higher current income than would be
available from a traditional equity security issued by the same
company, in return for reduced participation or a cap on appreciation
in the underlying common stock of the issuer which the holder can
realize. In addition, in many cases, enhanced convertible securities
are convertible into the underlying common stock of the issuer
automatically at maturity, unlike traditional convertible securities
which are convertible only at the option of the security holder.

The Fund may invest up to 10% of its total assets in "synthetic"
convertible securities. Unlike traditional convertible securities
whose conversion values are based on the common stock of the issuer
of the convertible security, "synthetic" convertible securities are
preferred stocks or debt obligations of an issuer which are combined
with an equity component whose conversion value is based on the value
of the common stock of a different issuer or a particular benchmark
(which may include a foreign issuer or basket of foreign stocks, or a
company whose stock is not yet publicly traded). In many cases,
"synthetic" convertible securities are not convertible prior to
maturity, at which time the value of the security is paid in cash by
the issuer.

<PAGE>

In addition, the Fund may invest in fixed-income securities, common
stocks that do not pay dividends, real estate investment trusts
("REITs") and foreign securities, including depository receipts.

The Fund also may invest up to 20% of its assets in fixed-income
securities rated lower than investment grade by S&P or Moody's (but
not below B) or if unrated of comparable quality as determined by the
Investment Manager (commonly known as "junk bonds"). The 20%
limitation is not applicable to convertible securities.

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.
Preferred stock pays dividends at a specified rate and has preference
over common stock in the payment of dividends. A convertible security
is a bond, preferred stock or other security that may be converted
into a prescribed amount of common stock at a prestated price.

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.

[GRAPHIC OMITTED]

PRINCIPAL RISKS
- --------------------------
There is no assurance that the Fund will achieve its investment
objectives. The Fund's share price will fluctuate with changes in the
market value of its 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.

Common and Preferred Stock. A principal risk of investing in the Fund
is associated with its investment in stocks. In particular the prices
of stocks can fluctuate widely in response to activities specific to
the issuer as well as general market, economic and political
conditions.

Fixed-Income Securities. Principal risks of investing in the Fund are
associated with its fixed-income investments. 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.)

<PAGE>

Convertible Securities. The Fund is also subject to the risks of
investing in convertible securities. These securities may carry risks
associated with both common stock and fixed-income securities. In
addition, because the convertible securities in which the Fund
invests are convertible into the common stocks of small and midcap
companies, the Fund is subject to the specific risks associated with
investing in small and midcap companies.

There are also special risks associated with the Fund's investments
in "enhanced" and "synthetic" convertible securities. These
securities may be more volatile and less liquid than traditional
convertible securities.

Small & Medium Capitalization Companies. The Fund's investments in
smaller and medium-sized companies carry more risk than investments
in larger companies. While some of the Fund's holdings in these
companies may be listed on a national securities exchange, such
securities are more likely to be traded in the over-the-counter
market. The low market liquidity of these securities may have an
adverse impact on the Fund's ability to sell certain securities at
favorable prices and may also make it difficult for the Fund to
obtain market quotations based on actual trades, for purposes of
valuing the Fund's securities. Investing in lesser-known, smaller and
medium capitalization companies involves greater risk of volatility
of the Fund's net asset value than is customarily associated with
larger, more established companies. Often smaller and medium
capitalization companies and the industries in which they are focused
are still evolving and, while this may offer better growth potential
than larger, more established companies, it also may make them more
sensitive to changing market conditions.

Junk Bonds. The Fund's investments in fixed-income securities rated
lower than investment grade, or if unrated, of comparable quality as
determined by the Investment Manager (commonly known as "junk bonds")
pose significant risks. The prices of junk bonds are likely to be
more sensitive to adverse economic changes or individual corporate
developments than higher rated securities. During an economic
downturn or substantial period of rising interest rates, junk bond
issuers and, in particular, highly leveraged issuers may experience
financial stress that would adversely affect their ability to service
their principal and interest payment obligations, to meet their
projected business goals or to obtain additional financing. In the
event of a default, the Fund may incur additional expenses to seek
recovery. The secondary market for junk bonds may be less liquid than
the market for higher quality securities and, as such, may have an
adverse effect on the market prices of certain securities. Rule 144A
securities could have the effect of increasing the level of Fund
illiquidity to the extent the Fund may be unable to find qualified
institutional buyers interested in purchasing the securities. The
illiquidity of the market may also adversely affect the ability of
the Fund's Trustees to arrive at a fair value for certain junk bonds
at certain times and could make it difficult for the Fund to sell
certain securities. In addition, periods of economic uncertainty and
change probably would result in an increased volatility of market
prices of high yield securities and a corresponding volatility in the
Fund's net asset value.

<PAGE>

Other Risks. The performance of the Fund also will depend on whether
the Investment Manager is successful in pursuing the Fund's
investment strategy. The Fund is also subject to other risks from its
permissible investments, including the risks associated with its
investments in real estate investment trusts (commonly known as
"REITs") and foreign securities, including depository receipts. 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 the FDIC or any other government agency.

(2) Investments that are not subject to any sales charge at the time of
purchase are subject to a contingent deferred sales charge ("CDSC") of
1.00% that will be imposed if you sell your shares within one year after
purchase, except for certain specific circumstances.

(3) The CDSC is scaled down to 1.00% during the sixth year, reaching zero
thereafter. See "Share Class Arrangements" for a complete discussion of the
CDSC.

(4) Only applicable if you sell your shares within one year after purchase.

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
(redeem) your shares at the end of each period.

ADDITIONAL INVESTMENT STRATEGY INFORMATION
- ---------------------------------------------------------
This section provides additional information relating to the Fund's
principal investment strategies.

Other Securities and Real Estate Investment Trusts. Up to 35% of the
Fund's total assets may be invested in U.S. government securities
issued or guaranteed as to principal and interest by the U.S.
government or its agencies or instrumentalities and investment grade
fixed-income securities (including zero coupon securities), common
stocks that do not pay a regular dividend and real estate investment
trusts (commonly known as "REITs").

Foreign Securities. The Fund may invest up to 25% of its total assets
in foreign securities (including depository receipts). This
percentage limitation, however, 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 of an
upswing in the market. When the Fund takes a defensive position, it
may not achieve its investment objective.

The percentage limitations relating to the composition of the Fund's
portfolio apply at the time the Fund acquires an investment and refer
to the Fund's net assets, unless otherwise noted. Subsequent
percentage changes that result from market fluctuations 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.

[GRAPHIC OMITTED]

ADDITIONAL RISK INFORMATION
- ----------------------------------------
This section provides additional information relating to the
principal risks of investing in the Fund.

Real Estate Investment Trusts ("REITs"). REITs pool investors funds
for investments primarily in commercial real estate properties. Like
mutual funds, REITs have

<PAGE>

expenses, including advisory and administration fees that are paid by
its shareholders. As a result, you will absorb duplicate levels of
fees when the Fund invests in REITs. The performance of any Fund REIT
holdings ultimately depends on the types of real property in which
the REITs invest and how well the property is managed. A general
downturn in real estate values also can hurt REIT performance.

Foreign Securities. Foreign securities (including depository
receipts) involve risks 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 effects of foreign social, economic or
political instability. Foreign companies, in general, are not subject
to the regulatory requirements of U.S. 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.

Many European countries have adopted or are in the process of
adopting a single European currency, referred to as the "euro." The
long-term consequences of the euro conversion for foreign exchange
rates, interest rates and the value of European securities the Fund
may purchase are unclear. The consequences may adversely affect the
value and/or increase the volatility of securities held by the Fund.

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
corporate 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.

<PAGE>

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.

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 $ billion in assets under
management or administration as of October 31, 1999.
[end sidebar]

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 Growth and Income Group. Paul D. Vance and
Peter M. Avelar, Senior Vice Presidents of the
Investment Manager, and Catherine Maniscalco, a Vice
President of the Investment Manager, have been the
primary portfolio co-managers of the Fund since its
inception in June 1996, January 1998 and July 1999,
respectively. Messrs. Vance and Avelar have been
portfolio managers with the Investment Manager for
over five years. Prior to joining the Investment
Manager in March 1995, Ms. Maniscalco was a portfolio
management software product specialist at National
Investor Data Services (April 1994-March 1995).

The Fund pays the Investment Manager a monthly
management fee as full compensation for the services
and facilities furnished to the Fund, and for Fund
expenses assumed by the Investment Manager. The fee is
based on the Fund's average daily net assets. For the
fiscal year ended September 30, 1999, the Fund accrued
total compensation to the Investment Manager amounting
to % of the Fund's average daily net assets.

<PAGE>

SHAREHOLDER INFORMATION

[GRAPHIC OMITTED]

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 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 may be valued at amortized cost. However, if the cost does
not reflect the securities' market value, these securities will be
valued at their fair value.

Financial Advisor or other authorized financial representative can
help you decide which Class may be most appropriate for you. When
purchasing Fund shares, you must specify which Class of shares you
wish to purchase.

When you buy Fund shares, the shares are purchased at the next share
price calculated (less any applicable front-end sales charge for
Class A shares) after we receive your purchase order. Your payment is
due on the third business day after you place your purchase order. We
reserve the right to reject any order for the purchase of Fund
shares.

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, a Money Market
Fund, North American Government Income Trust 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. Since exchanges are available only into
continuously offered Morgan Stanley Dean Witter Funds, exchanges are
not available into any new Morgan Stanley Dean Witter Fund during its
initial offering period, or when shares of a particular Morgan
Stanley Dean Witter Fund are not being offered for purchase.

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. The check writing privilege is 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

<PAGE>

requiring various forms of personal identification such as name,
mailing address, social security or other tax identification number.
Telephone instructions also may be recorded.

Telephone instructions will be accepted if received by the Fund's
transfer agent between 9:00 a.m. and 4:00 p.m. Eastern time, on any
day the New York Stock Exchange is open for business. During periods
of drastic economic or market changes, it is possible that the
telephone exchange procedures may be difficult to implement, although
this has not been the case with the Fund in the past.

Margin Accounts. If you have pledged your Fund shares in a margin
account, contact your Morgan Stanley Dean Witter Financial Advisor or
other authorized financial representative regarding restrictions on
the exchange of such shares.

Tax Considerations of Exchanges. If you exchange shares of the Fund
for shares of another Morgan Stanley Dean Witter Fund there are
important tax considerations. For tax purposes, the exchange out of
the Fund is considered a sale of Fund shares -- and the exchange into
the other Fund is considered a purchase. As a result, you may realize
a capital gain or loss.

You should review the "Tax Consequences" section and consult your own
tax professional about the tax consequences of an exchange.

Frequent Exchanges. A pattern of frequent exchanges may result in the
Fund limiting or prohibiting, at its discretion, additional purchases
and/or exchanges. The Fund will notify you in advance of limiting
your exchange privileges.

CDSC Calculations on Exchanges. See the "Share Class Arrangements"
section of this Prospectus for a further 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.

Withdrawal Plan market value of at least $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
[GRAPHIC OMITTED] a monthly, quarterly, semi-annual or annual basis, from any Fund with a balance of at least
$1,000. Each time you add a Fund to the plan, you must meet the plan requirements.

Amounts withdrawn are subject to any applicable CDSC. A CDSC may be waived
under certain circumstances. See the Class B waiver categories listed in the "Share Class
Arrangements" section of this Prospectus.
--------------------------------------------------------------------------------------------
To sign up for the Systematic Withdrawal Plan, contact your Morgan Stanley Dean
Witter Financial Advisor or call (800) 869-NEWS. You may terminate or suspend your
plan at any time. Please remember that withdrawals from the plan are sales of shares,
not Fund "distributions," and ultimately may exhaust your account balance. The Fund
may terminate or revise the plan at any time.
</TABLE>

<PAGE>

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.

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.

DISTRIBUTIONS
- ------------------------
[sidebar]
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]

The Fund passes substantially all of its earnings from income and
capital gains along to its investors as "distributions." The Fund
earns interest from fixed-income investments and income from stocks.
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
usually will be higher than for Class B and Class C because
distribution fees that Class B and Class C pay are higher.
Normally, income dividends are distributed to shareholders
quarterly. Capital gains, if any, are usually distributed 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.

[GRAPHIC OMITTED]

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.

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:

o The Fund makes distributions; and
o 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

<PAGE>

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.

[GRAPHIC OMITTED]

SHARE CLASS ARRANGEMENTS
- -------------------------------------
The Fund offers several Classes of shares having different
distribution arrangements designed to provide you with different
purchase options according to your investment needs. Your Morgan
Stanley Dean Witter Financial Advisor or other authorized financial
representative can help you decide which Class may be appropriate for
you.

The general public is offered three Classes: Class A shares, Class B
shares and Class C shares, which differ principally in terms of sales
charges and ongoing expenses. A fourth Class, Class D shares, is
offered only to a limited category of investors. Shares that you
acquire through reinvested distributions will not be subject to any
front-end sales charge or CDSC -- contingent deferred sales charge.
Sales personnel may receive different compensation for selling each
Class of shares. The sales charges applicable to each Class provide
for the distribution financing of shares of that Class.

<PAGE>

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

<TABLE>
<CAPTION>
MAXIMUM
CLASS SALES CHARGE ANNUAL 12B-1 FEE
- ----- ------------ ----------------
<S> <C> <C>

B Maximum 5.0% CDSC during the first year decreasing to 0% after six years 1.00%
C 1.0% CDSC during the first year 1.00%
D None None
</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:

[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.

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

o A single account (including an individual, trust or fiduciary
account).
o Family member accounts (limited to husband, wife and children
under the age of 21).
o Pension, profit sharing or other employee benefit plans of
companies and their affiliates.
o Tax-exempt organizations.
o Groups organized for a purpose other than to buy mutual fund
shares.

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

<PAGE>

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, which may be deducted
from your investment.

Other Sales Charge Waivers. In addition to investments of $1 million
or more, your purchase of Class A shares is not subject to a
front-end sales charge (or a CDSC upon sale) if your account
qualifies under one of the following categories:

o A trust for which Morgan Stanley Dean Witter Trust FSB provides
discretionary trustee services.

o 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.

o 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.

o An 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.

o 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.

o 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.

o 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.

<PAGE>

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.

[sidebar]
CONTINGENT DEFERRED SALES

Seventh and thereafter None
</TABLE>

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:

o 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.

o 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).

o Sales of shares held for you as a participant in an MSDW Eligible
Plan.

o 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

<PAGE>

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 Fund's distributor
receiving confirmation of your entitlement. If you believe you are
eligible for a CDSC waiver, please contact your Financial Advisor or
call (800) 869-NEWS.

Distribution Fee. Class B shares are also subject to an annual 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.

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 an 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, a No-Load Fund, North American Government Income Trust 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

<PAGE>

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.

CLASS C SHARES Class C shares are sold at net asset value with no
initial sales charge but are subject to a CDSC of 1.0% on sales made
within one year after the last day of the month of purchase. The CDSC
will be assessed in the same manner and with the same CDSC waivers as
with Class B shares.

Distribution Fee. Class C shares are subject to an annual
distribution (12b-1) fee of 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 certain MSDW Eligible Plans)
and the following investor categories:

o 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.

<PAGE>

o 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.

o Certain unit investment trusts sponsored by Dean Witter Reynolds.

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

o 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 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.

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 a
Declaration of Trust, on March 21, 1996, with the name Dean Witter Income
Builder Fund. On June 22, 1998, the Fund's name was changed to Morgan Stanley
Dean Witter Income Builder Fund.

II. DESCRIPTION OF THE FUND AND ITS INVESTMENTS AND RISKS
- --------------------------------------------------------------------------------

A. CLASSIFICATION

The Fund is an open-end, diversified management investment company whose
primary investment objective is to seek reasonable income. As a secondary
objective, the Fund seeks growth of capital.

B. INVESTMENT STRATEGIES AND RISKS

The following discussion of the Fund's investment strategies and risks
should be read with the sections of the Fund's Prospectus titled "Principal
Investment Strategies," "Principal Risks," "Additional Investment Strategy
Information," and "Additional Risk Information."

MONEY MARKET SECURITIES. The Fund may invest in various money market
securities for cash management purposes, which among others may include
commercial paper, bank acceptances, bank obligations, corporate debt
securities, certificates of deposit, U.S. Government securities, obligations of
savings institutions and repurchase agreements. Such securities include:

U.S. or Foreign 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

4
<PAGE>

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.

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. From
time to time the Fund may purchase securities on a when-issued or delayed
delivery basis or may purchase or sell securities on a forward commitment
basis. When these transactions are negotiated, the price is fixed at the time
of the commitment, but delivery and payment can take place a month or more
after the date of commitment. While the Fund will only purchase securities on a
when-issued, delayed delivery or forward commitment basis with the intention of
acquiring the securities, the Fund may sell the securities before the
settlement date, if it is deemed advisable. The securities so purchased or sold
are subject to market fluctuation and no interest or dividends accrue to the
purchaser prior to the settlement date.

At the time the Fund makes the commitment to purchase or sell securities
on a when-issued, delayed delivery or forward commitment basis, it will record
the transaction and thereafter reflect the value, each day, of such security
purchased, or if a sale, the proceeds to be received, in determining its net
asset value. At the time of delivery of the securities, their value may be more
or less than the purchase or sale price. An increase in the percentage of the
Fund's assets committed to the purchase of securities on a when-issued, delayed
delivery or forward commitment basis may increase the volatility of its net
asset value. The Fund will also establish a segregated account on the Fund's
books in which it will continually maintain cash or cash equivalents or other
liquid portfolio securities equal in value to commitments to purchase
securities on a when-issued, delayed delivery or forward commitment basis.

5
<PAGE>

WHEN, AS AND IF ISSUED SECURITIES. The Fund may purchase securities on a
"when, as and if issued" basis under which the issuance of the security depends
upon the occurrence of a subsequent event, such as approval of a merger,
corporate reorganization or debt restructuring. The commitment for the purchase
of any such security will not be recognized in the portfolio of the Fund until
the Investment Manager determines that issuance of the security is probable. At
that time, the Fund will record the transaction and, in determining its net
asset value, will reflect the value of the security daily. At that time, the
Fund will also establish a segregated account on the Fund's books in which it
will maintain cash or cash equivalents or other liquid portfolio securities
equal in value to recognized commitments for such securities.

The value of the Fund's commitments to purchase the securities of any one
issuer, together with the value of all securities of such issuer owned by the
Fund, may not exceed 5% of the value of the Fund's total assets at the time the
initial commitment to purchase such securities is made. An increase in the
percentage of the Fund's 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.

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 objectives, policies and restrictions listed below have
been adopted by the Fund as fundamental policies. Under the Investment Company
Act of 1940 (the "Investment Company Act"), a fundamental policy may not be
changed without the vote of a majority of the outstanding voting securities of
the Fund. The Investment Company Act defines a majority as the lesser of (a)
67% or more of the shares present at a meeting of shareholders, if the holders
of 50% of the outstanding shares of the Fund are present or represented by
proxy; or (b) more than 50% of the outstanding shares of the Fund. 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. As a primary objective, seek reasonable income.

2. As a secondary objective, seek growth of capital.

6
<PAGE>

The Fund may not:

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

2. Purchase more than 10% of all outstanding voting securities or any
class of securities of any one issuer.

3. Invest 25% or more of the value of its total assets in securities of
issuers in any one industry. This restriction does not apply to
obligations issued or guaranteed by the United States Government, its
agencies or instrumentalities.

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

5. Invest in securities of any issuer if in the exercise of reasonable
diligence, the Fund has determined that any officer or trustee/director
of the Fund or of the Investment Manager owns more than 1/2 of 1% of the
outstanding securities of such issuer, and such officers and
trustees/directors who own more than 1/2 of 1% own in the aggregate more
than 5% of the outstanding securities of such issuer.

6. 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.

7. Purchase or sell commodities.

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 such
programs.

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

10. 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).

11. Pledge its assets or assign or otherwise encumber them except to secure
permitted borrowings.

12. 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: (a) entering into any repurchase agreement; (b) borrowing
money; (c) purchasing any securities on a when-issued or delayed delivery
basis; or (d) lending portfolio securities.

13. Make loans of money or securities, except by: (a) the purchase of debt
obligations in which the Fund may invest consistent with its investment
objective and policies; (b) investment in repurchase agreements; and (c)
lending its portfolio securities.

14. Make short sales of securities.

15. Purchase securities on margin, except for such short-term loans as are
necessary for the clearance of portfolio securities.

16. Engage in the underwriting of securities, except insofar as the Fund
may be deemed an underwriter under the Securities Act of 1933 in
disposing of a portfolio security.

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

7
<PAGE>

In addition, as non-fundamental policies, the Fund will not invest in
options or futures contracts or in more than 5% of the value of its net assets
in warrants, including not more than 2% of such assets in warrants not listed
on the New York or American Stock Exchange. However, the acquisition of
warrants attached to other securities is not subject to this restriction.

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
Trustees also serve as Trustees of "Discover Brokerage Index Series," a mutual
fund for which the Investment Manager is the investment advisor.

The Trustees and executive officers of the Fund, their principal business
occupations during the last five years and their affiliations, if any, with the

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

11
<PAGE>

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/trustees 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 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.

TRUSTEE AND OFFICER INDEMNIFICATION. The Fund's Declaration of Trust
provides that no Trustee, officer, employee or agent of the Fund is liable to
the Fund or to a shareholder, nor is any Trustee, officer, employee or agent
liable to any third persons in connection with the affairs of the Fund, except
as such liability may arise from his/her or its own bad faith, willful
misfeasance, gross negligence or reckless disregard of his/her or its duties.
It also provides that all third persons shall look solely to the Fund property
for satisfaction of claims arising in connection with the affairs of the Fund.
With the exceptions stated, the Declaration of Trust provides that a Trustee,
officer, employee or agent is entitled to be indemnified against all liability
in connection with the affairs of the Fund.

C. COMPENSATION

The Fund pays each Independent Trustee an annual fee of $800 plus a per
meeting fee of $50 for meetings of the Board of Trustees, the Independent
Trustees or Committees of the Board of Trustees

12
<PAGE>

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 September 30, 1999.

As of the date of this Statement of Additional Information, 55 of the
Morgan Stanley Dean Witter Funds, not 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 Trustee referred to as an
"Eligible Trustee") is entitled to retirement payments upon reaching the
eligible retirement age (normally, after attaining age 72). Annual payments are
based upon length of service.

Currently, upon retirement, each Eligible Trustee is entitled to receive
from the Adopting Fund, commencing as of his or her retirement date and
continuing for the remainder of his or her life, an annual retirement benefit
(the "Regular Benefit") equal to 30.22% of his or her Eligible Compensation
plus

13
<PAGE>

0.5036667% of such Eligible Compensation for each full month of service as an
Independent Director/Trustee of any Adopting Fund in excess of five years up to
a maximum of 60.44% 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 accrued as expenses on the books of
the Adopting Funds. Such benefits 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 55 Morgan Stanley Dean Witter Funds (not
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 Stanley Dean Witter Funds as of December 31,
1998.

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

- --------------
(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. In
addition, the Eligible Trustee may elect that the surviving spouse's
periodic payment of benefits will be equal to a lower percentage of the
periodic amount when both spouses were alive. The amount estimated to be
payable under this method, through the remainder of the later of the lives
of the Eligible Trustee and spouse, will be the actuarial equivalent of the
Regular Benefit.

(2) Based on current levels of compensation. Amount of annual benefits also
varies depending on the Trustee's elections described in Footnote (1) on
page 13.

14
<PAGE>

and manage the investment of the Fund's assets, including the placing of orders
for the purchase and sale of portfolio securities. The Fund pays the Investment
Manager monthly compensation calculated daily by applying the following annual
rates to the net assets of the Fund determined as of the close of each business
day: 0.75% to the portion of daily net assets not exceeding $500 million; and
0.725% to the portion of daily net assets exceeding $500 million. The
management fee is allocated among the Classes pro rata based on the net assets
of the Fund attributable to each Class. For the fiscal years ended September
30, 1997, 1998 and 1999, the Investment Manager accrued total compensation
under the Management Agreement in the amounts of $1,868,871, $3,387,158 and
$ , respectively.

The Investment Manager has retained its wholly-owned subsidiary, MSDW
Services Company, to perform administrative services for the Fund.

B. PRINCIPAL UNDERWRITER

The Fund's principal underwriter is the Distributor (which has the same
address as the Investment Manager). In this capacity, the Fund's shares are
distributed by the Distributor. The Distributor has entered into a selected
dealer agreement with Dean Witter Reynolds, which through its own sales
organization sells shares of the Fund. In addition, the Distributor may enter
into similar agreements with other selected broker-dealers. The Distributor, a
Delaware corporation, is a wholly-owned subsidiary of MSDW.

The Distributor bears all expenses it may incur in providing services
under the Distribution Agreement. These expenses include the payment of
commissions for sales of the Fund's shares and incentive compensation to
Financial Advisors. The Distributor also pays certain expenses in connection
with the distribution of the Fund's shares, including the costs of preparing,
printing and distributing advertising or promotional materials, and the costs
of printing and distributing prospectuses and supplements thereto used in
connection with the offering and sale of the Fund's shares. The Fund bears the
costs of initial typesetting, printing and distribution of prospectuses and
supplements thereto to shareholders. The Fund also bears the costs of
registering the Fund and its shares under federal and state securities laws and
pays filing fees in accordance with state securities laws.

The Fund and the Distributor have agreed to indemnify each other against
certain liabilities, including liabilities under the Securities Act. Under the
Distribution Agreement, the Distributor uses its best efforts in rendering
services to the Fund, but in the absence of willful misfeasance, bad faith,
gross negligence or reckless disregard of its obligations, the Distributor is
not liable to the Fund or any of its shareholders for any error of judgment or
mistake of law or for any act or omission or for any losses sustained by the
Fund or its shareholders.

C. SERVICES PROVIDED BY THE INVESTMENT MANAGER AND FUND EXPENSES PAID BY THIRD
PARTIES

The Investment Manager manages the investment of the Fund's assets,
including the placing of orders for the purchase and sale of portfolio
securities. The Investment Manager obtains and evaluates the information and
advice relating to the economy, securities markets, and specific securities as
it considers necessary or useful to continuously manage the assets of the Fund
in a manner consistent with its investment objective.

Under the terms of the Management Agreement, in addition to managing the
Fund's investments, the Investment Manager maintains certain of the Fund's
books and records and furnishes, at its own expense, the office space,
facilities, equipment, clerical help, bookkeeping and certain legal services as
the Fund may reasonably require in the conduct of its business, including the
preparation of prospectuses, proxy statements and reports required to be filed
with federal and state securities commissions (except insofar as the
participation or assistance of independent accountants and attorneys is, in the
opinion of the Investment Manager, necessary or desirable). In addition, the
Investment Manager pays the salaries of all personnel, including officers of
the Fund, who are employees of the Investment Manager. The Investment Manager
also bears the cost of telephone service, heat, light, power and other
utilities provided to the Fund.

15
<PAGE>

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 or personnel (including officers and Trustees)
of the Fund which inure to its benefit; extraordinary expenses (including, but
not limited to, legal claims and liabilities and litigation costs and any
indemnification relating thereto); and all other costs of the Fund's operation.
The 12b-1 fees relating to a particular Class will be allocated directly to
that Class. In addition, other expenses associated with a particular Class
(except advisory or custodial fees) may be allocated directly to that Class,
provided that such expenses are reasonably identified as specifically
attributable to that Class and the direct allocation to that Class is approved
by the Trustees.

The Management Agreement provides that in the absence of willful
misfeasance, bad faith, gross negligence or reckless disregard of its
obligations thereunder, the Investment Manager is not liable to the Fund or any
of its investors for any act or omission by the Investment Manager or for any
losses sustained by the Fund or its investors.

The Management Agreement will remain in effect from year to year, provided
continuance of the Management Agreement is approved at least annually by the
vote of the holders of a majority, as defined in the Investment Company Act, of
the outstanding shares of the Fund, or by the Trustees; provided that in either
event such continuance is approved annually by the vote of a majority of the
Trustees.

D. DEALER REALLOWANCES

Upon notice to selected broker-dealers, the Distributor may reallow up to
the full applicable front-end sales charge during periods specified in such
notice. During periods when 90% or more of the sales charge is reallowed, such
selected broker-dealers may be deemed to be underwriters as that term is
defined in the Securities Act.

E. RULE 12b-1 PLAN

The Fund has adopted a Plan of Distribution pursuant to Rule 12b-1 under
the Investment Company Act (the "Plan") pursuant to which each Class, other
than Class D, pays the Distributor compensation accrued daily and payable
monthly at the following annual rates: 0.25% and 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 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

16
<PAGE>

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 September 30, in approximate
amounts as provided in the table below (the Distributor did not retain any of
these amounts).

(1) FSCs apply to Class A only.

(2) 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 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 September 30, 1999, of $ . This amount is equal to % of
the average daily net assets of Class B for the fiscal year and was calculated
pursuant to clause ( ) of the compensation formula under the Plan. For the
fiscal year ended September 30, 1999, Class A and Class C shares of the Fund
accrued payments under the Plan amounting to $ and $ , respectively,
which amounts are equal to % and % 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

17
<PAGE>

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).

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.

18
<PAGE>

Each Class paid 100% of the amounts accrued under the Plan with respect to
that Class for the fiscal year ended September 30, 1999 to the Distributor. The
Distributor and Dean Witter Reynolds estimate that they have spent, pursuant to
the Plan, $ on behalf of Class B since the inception of the Plan. It
is estimated that this amount was spent in approximately the following ways:
(i) % ($ )--advertising and promotional expenses; (ii) %
($ )--printing of prospectuses for distribution to other than current
shareholders; and (iii) % ($ )--other expenses, including the
gross sales credit and the carrying charge, of which % ($ )
represents carrying charges, % ($ ) represents commission credits
to Dean Witter Reynolds branch offices and other selected broker-dealers for
payments of commissions to Financial Advisors and other authorized financial
representatives, and % ($ ) represents overhead and other branch
office distribution-related expenses. The amounts accrued by Class A and a
portion of the amounts accrued by Class C under the Plan during the fiscal year
ended September 30, 1999 were service fees. The remainder of the amounts
accrued by Class C were for expenses which relate to compensation of sales
personnel and associated overhead expenses.

In the case of Class B shares, at any given time, the expenses of
distributing shares of the Fund may be more or less than the total of (i) the
payments made by the Fund pursuant to the Plan; and (ii) the proceeds of CDSCs
paid by investors upon redemption of shares. For example, if $1 million in
expenses in distributing Class B shares of the Fund had been incurred and
$750,000 had been received as described in (i) and (ii) above, the excess
expense would amount to $250,000. The Distributor has advised the Fund that in
the case of Class B shares the excess distribution expenses, including the
carrying charge designed to approximate the opportunity costs incurred by Dean
Witter Reynolds which arise from it having advanced monies without having
received the amount of any sales charges imposed at the time of sale of the
Fund's Class B shares, totaled $ as of September 30, 1999 (the end of
the Fund's fiscal year), which was equal to % 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 financial representatives at the time of sale may
be reimbursed in the subsequent calendar year. The Distributor has advised the
Fund that there were no such expenses that may be reimbursed in the subsequent
year in the case of Class A or Class C at December 31, 1998 (the end of the
calendar year). No interest or other financing charges will be incurred on any
Class A or Class C distribution expenses incurred by the Distributor under the
Plan or on any unreimbursed expenses due to the Distributor pursuant to the
Plan.

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

19
<PAGE>

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, 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 Board of Trustees, the
Investment Manager is responsible for decisions to buy and sell securities for
the Fund, the selection of brokers and dealers to effect the transactions, and
the negotiation of brokerage commissions, if any. Purchases and sales of
securities on a stock exchange are effected through brokers who charge a
commission for their services. In the over-the-counter market, securities are
generally traded on a "net" basis with dealers acting as principal for their
own accounts without a stated commission, although the price of the security
usually includes a profit to the dealer. The Fund expects that securities will
be purchased at times in underwritten offerings where the price includes a
fixed amount of compensation, generally referred to as the underwriter's
concession or discount. Options and futures transactions will usually be
effected through a broker and a commission will be charged. On occasion, the
Fund may also purchase certain money market instruments directly from an
issuer, in which case no commissions or discounts are paid.

For the fiscal years ended September 30, 1997, 1998 and 1999, the Fund
paid a total of $224,501, $314,715 and $ , 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 September 30, 1997, 1998 and 1999, 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 September 30, 1997, 1998 and 1999, the Fund
paid a total of $82,810, $141,296 and $ , respectively, in brokerage
commissions to Dean Witter Reynolds. During the fiscal year ended September 30,
1999, the brokerage commissions paid to Dean Witter Reynolds represented
approximately % of the total commissions paid by the Fund during the year
and were paid on account of transactions having an aggregate dollar value equal
to approximately % 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 September 30, 1997 and during the fiscal
years ended September 30, 1998 and 1999, the Fund paid a total of $0, $6,600
and $ , 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 September 30, 1999, the
brokerage

21
<PAGE>

commissions paid to Morgan Stanley & Co. represented approximately % 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
% 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
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.

The Fund anticipates that certain of its transactions involving foreign
securities will be effected on securities exchanges. Fixed commissions on such
transactions are generally higher than negotiated commissions on domestic
transactions. There is also generally less government supervision and
regulation of foreign securities exchanges and brokers than in the United
States.

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 serves as investment manager to a number
of clients, including other investment companies, and may in the future act as
investment manager or advisor to others. It is the practice of the Investment
Manager to cause purchase and sale transactions to be allocated among the Fund
and others whose assets it manages in such manner as it deems equitable. In
making such allocations among the Fund and other client accounts, various
factors may be considered, including the respective investment objectives, the
relative size of portfolio holdings of the same or comparable securities, the
availability of cash for investment, the size of investment commitments
generally held and the opinions of the persons responsible for managing the
portfolios of the Fund and other client accounts. In the case of certain
initial and secondary public offerings, the Investment Manager utilizes a pro
rata allocation process based on the size of the Morgan Stanley Dean Witter
Funds involved and the number of shares available from the public offering.

D. DIRECTED BROKERAGE

During the fiscal year ended September 30, 1999, the Fund paid $ in
brokerage commissions in connection with transactions in the aggregate amount
of $ to brokers because of research services provided.

22
<PAGE>

E. REGULAR BROKER-DEALERS

During the fiscal year ended September 30, 1999, the Fund did not purchase
securities issued by brokers or dealers that were among the ten brokers or the
ten dealers that 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 except that each Class will have exclusive voting privileges with
respect to matters relating to distribution expenses borne solely by such Class
or any other matter in which the interests of one Class differ from the
interests of any other Class. In addition, Class B shareholders will have the
right to vote on any proposed material increase in Class A's expenses, if such
proposal is submitted separately to Class A shareholders. Also, Class A, Class
B and Class C bear expenses related to the distribution of their respective
shares.

The Fund's Declaration of Trust permits the Trustees to authorize the
creation of additional series of shares (the proceeds of which would be
invested in separate, independently managed portfolios) and additional Classes
of shares within any series. The Trustees have not presently authorized any
such additional series or Classes of shares other than as set forth in the
Prospectus.

The Fund is not required to hold annual meetings of shareholders and in
ordinary circumstances the Fund does not intend to hold such meetings. The
Trustees may call special meetings of shareholders for action by shareholder
vote as may be required by the Investment Company Act or the Declaration of
Trust. Under certain circumstances, the Trustees may be removed by action of
the Trustees. The voting rights of shareholders are not cumulative, so that
holders of more than 50 percent of the shares voting can, if they choose, elect
all Trustees being selected, while the holders of the remaining shares would be
unable to elect any Trustees. In addition, under certain circumstances, the
shareholders may call a meeting to remove Trustees and the Fund is required to
provide assistance in communicating with shareholders about such a meeting.

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/REDEMPTION OF SHARES

Information concerning how Fund shares are offered to the public (and how
they are redeemed and exchanged) is provided in the Fund's Prospectus.

TRANSFER AGENT AS AGENT. With respect to the redemption or repurchase of
Fund shares, the application of proceeds to the purchase of new shares in the
Fund or any other Morgan Stanley Dean Witter Funds and the general
administration of the exchange privilege, the Transfer Agent acts as agent for
the Distributor and for the shareholder's authorized broker-dealer, if any, in
the performance of such functions. With respect to exchanges, redemptions or
repurchases, the Transfer Agent shall be liable for its own negligence and not
for the default or negligence of its correspondents or for losses in transit.
The Fund shall not be liable for any default or negligence of the Transfer
Agent, the Distributor or any authorized broker-dealer.

The Distributor and any authorized broker-dealer have appointed the
Transfer Agent to act as their agent in connection with the application of
proceeds of any redemption of Fund shares to the purchase of shares of any
other Morgan Stanley Dean Witter Fund and the general administration of the
exchange privilege. No commission or discounts will be paid to the Distributor
or any authorized broker-dealer for any transaction pursuant to the exchange
privilege.

TRANSFERS OF SHARES. In the event a shareholder requests a transfer of
Fund shares to a new registration, the shares will be transferred without sales
charge at the time of transfer. With regard to the status of shares which are
either subject to the CDSC or free of such charge (and with regard to the
length of time shares subject to the charge have been held), any transfer
involving less than all of the shares in an account will be made on a pro rata
basis (that is, by transferring shares in the same proportion that the
transferred shares bear to the total shares in the account immediately prior to
the transfer). The transferred shares will continue to be subject to any
applicable CDSC as if they had not been so transferred.

B. OFFERING PRICE

The Fund's Class B, Class C and Class D shares are offered at net asset
value per share and the Class A shares are offered at net asset value per share
plus any applicable FSC which is distributed among the Fund's Distributor, Dean
Witter Reynolds and other authorized dealers as described in Section "V.
Investment Management and Other Services--E. Rule 12b-1 Plan."

The price of 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.

24
<PAGE>

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

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 maximum tax on long-term capital
gains applicable to individuals is 20%.

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 and the portion taxable as
long-term capital gains.

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. Under current law, the maximum tax on long-term capital gains is
20%. Any loss realized by shareholders upon a sale or 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."

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. Based on this calculation, the average annual total returns for Class B
for the one year period ended September 30, 1999 and for the period June 26,
1996 (commencement of operations) through September 30, 1999 were % and
%, respectively. The average annual total returns of Class A for the fiscal
year ended September 30, 1999 and for the period July 28, 1997 (inception of
the Class) through September 30, 1999 were % and %, respectively. The
average annual total returns of Class C for the fiscal year ended September 30,
1999 and for the period July 28, 1997 (inception of the Class) through
September 30, 1999 were % and %, respectively. The average annual total
returns of Class D for the fiscal year ended September 30, 1999 and for the
period July 28, 1997 (inception of the Class) through September 30, 1999 were
% and %, 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 period ended September 30, 1999 and
for the period June 26, 1996 (commencement of operations) through September 30,
1999 were % and %, respectively. The average annual total returns of
Class A for the fiscal year ended September 30, 1999 and for the period July
28, 1997 through September 30, 1999 were % and %, respectively. The
average annual total returns of Class C for the fiscal year ended September 30,
1999 and for the period July 28, 1997 through September 30, 1999 were % and
%, respectively. The average annual total returns of Class D for the fiscal
year ended September 30, 1999 and for the period July 28, 1997 through
September 30, 1999 were % and %, 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 this calculation, the total returns
for Class B for the one year period ended September 30, 1999 and for the period
June 26, 1996 (commencement of operations) through September 30, 1999 were
% and %, respectively. The total returns of Class A for the fiscal year
ended September 30, 1999 and for the period July 28, 1997

27
<PAGE>

through September 30, 1999 were % and %, respectively. The total
returns of Class C for the fiscal year ended September 30, 1999 and for the
period July 28, 1997 through September 30, 1999 were % and %,
respectively. The total returns of Class D for the fiscal year ended September
30, 1999 and for the period July 28, 1997 through September 30, 1999 were %
and %, respectively.

The Fund may also advertise the growth of hypothetical investments of
$10,000, $50,000 and $100,000 in each Class of shares of the Fund by adding 1
to the Fund's aggregate total return to date (expressed as a decimal and
without taking into account the effect of any applicable CDSC) and multiplying
by $9,475, $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 September
30, 1999:

Item 25. Indemnification.
----------------

Pursuant to Section 5.3 of the Registrant's Declaration of Trust and under
Section 4.8 of the Registrant's By-Laws, the indemnification of the Registrant's
trustees, officers, employees and agents is permitted if it is determined that
they acted under the belief that their actions were in or not opposed to the
best interest of the Registrant, and, with respect to any criminal proceeding,
they had reasonable cause to believe their conduct was not unlawful. In
addition, indemnification is permitted only if it is

<PAGE>

determined that the actions in question did not render them liable by reason of
willful misfeasance, bad faith or gross negligence in the performance of their
duties or by reason of reckless disregard of their obligations and duties to the
Registrant. Trustees, officers, employees and agents will be indemnified for the
expense of litigation if it is determined that they are entitled to
indemnification against any liability established in such litigation. The
Registrant may also advance money for these expenses provided that they give
their undertakings to repay the Registrant unless their conduct is later
determined to permit indemnification.

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

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

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

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

<PAGE>

BY-LAWS

MORGAN STANLEY DEAN WITTER INCOME BUILDER FUND

AMENDED AND RESTATED AS OF MAY 1, 1999

ARTICLE I

DEFINITIONS

The terms "Commission," "Declaration," "Distributor," "Investment Adviser,"
"Majority Shareholder Vote," "1940 Act," "Shareholder," "Shares," "Transfer
Agent," "Trust," "Trust Property," and "Trustees" have the respective meanings
given them in the Declaration of Trust of Morgan Stanley Dean Witter Income
Builder Fund dated March 20, 1996, as amended from time to time.

ARTICLE II

OFFICES

SECTION 2.1. Principal Office. Until changed by the Trustees, the
principal office of the Trust in the Commonwealth of Massachusetts shall be in
the City of Boston, County of Suffolk.

SECTION 2.2. Other Offices. In addition to its principal office in the
Commonwealth of Massachusetts, the Trust may have an office or offices in the
City of New York, State of New York, and at such other places within and
without the Commonwealth as the Trustees may from time to time designate or the
business of the Trust may require.

ARTICLE III

SHAREHOLDERS' MEETINGS

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

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

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

<PAGE>

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

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

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

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

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

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

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

2
<PAGE>

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

SECTION 3.8. Inspection of Books and Records. Shareholders shall have such
rights and procedures of inspection of the books and records of the Trust as
are granted to Shareholders under Section 32 of the Business Corporation Law of
the Commonwealth of Massachusetts.

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

ARTICLE IV

TRUSTEES

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

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

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

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

SECTION 4.5. Action by Trustees Without Meeting. The provisions of these
By-Laws covering notices and meetings to the contrary notwithstanding, and
except as required by law, any action required or permitted to be taken at any
meeting of the Trustees may be taken without a meeting if a consent in

3
<PAGE>

writing setting forth the action shall be signed by all of the Trustees
entitled to vote upon the action and such written consent is filed with the
minutes of proceedings of the Trustees.

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

SECTION 4.7. Execution of Instruments and Documents and Signing of Checks
and Other Obligations and Transfers. All instruments, documents and other
papers shall be executed in the name and on behalf of the Trust and all checks,
notes, drafts and other obligations for the payment of money by the Trust shall
be signed, and all transfer of securities standing in the name of the Trust
shall be executed, by the President, any Vice President or the Treasurer or by
any one or more officers or agents of the Trust as shall be designated for that
purpose by vote of the Trustees.

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

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

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

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

4
<PAGE>

(2) The determination shall be made:

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

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

(iii) By the Shareholders.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

COMMITTEES

SECTION 5.1. Executive and Other Committees. The Trustees, by resolution
adopted by a majority of the Trustees, may designate an Executive Committee
and/or committees, each committee to consist of two (2) or more of the Trustees
of the Trust and may delegate to such committees, in the intervals between
meetings of the Trustees, any or all of the powers of the Trustees in the
management of the business and affairs of the Trust. In the absence of any

whether or not they constitute a quorum, may appoint a Trustee to act in place
of such absent member. Each such committee shall keep a record of its

at the meeting thereof next succeeding to the taking of such action.

by the Trust. The number of persons constituting any such advisory committee
shall be determined from time to time by the Trustees. The members of any such

allowed such fees and expenses for the attendance at meetings as the Trustees
may from time to time determine to be appropriate.

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

DIVIDENDS AND DISTRIBUTIONS

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

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

CERTIFICATES OF SHARES

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

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

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

SECTION 8.2. Lost, Stolen, Destroyed and Mutilated Certificates. The
Trustees may direct a new certificate or certificates to be issued in place of

<PAGE>

of such loss, theft, or destruction; and the Trustees may, in their discretion,
require the owner of the lost, stolen or destroyed certificate, or his legal
representative, to give to the Trust and to such Registrar, Transfer Agent
and/or Transfer Clerk as may be authorized or required to countersign such new
certificate or certificates, a bond in such sum and of such type as they may
direct, and with such surety or sureties, as they may direct, as indemnity
against any claim that may be against them or any of them on account of or in
connection with the alleged loss, theft or destruction of any such certificate.

ARTICLE IX

CUSTODIAN

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

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

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

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

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

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

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

ARTICLE X

WAIVER OF NOTICE

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

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

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

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

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

ARTICLE XII

compliance by the Trust is required.

ARTICLE XIII

AMENDMENTS

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