INVESTMENT OBJECTIVES

The FLORIDA MUNICIPAL FUNDS seek to obtain as high a level of current income
exempt from regular federal income tax as is consistent with prudent investment
management and conservation of shareholders' capital. In addition, Fund shares
are intended to be exempt from the Florida intangibles tax.

The NATIONAL TAX-FREE FUNDS seek as high a level of current income exempt from
federal income taxes as is consistent with prudent investment management and
conservation of shareholders' capital.

The investment objective for each Fund described in this Prospectus is
fundamental and may not be changed without shareholder approval. Unless
otherwise noted, the other policies described in this Prospectus are not
fundamental and may be changed by the board of trustees. There is no guarantee
that the Funds will achieve their investment objectives.

INVESTMENT POLICIES

BENHAM FLORIDA MUNICIPAL FUNDS

Each Florida Municipal Fund is a "non-diversified company" as defined in the
Investment Company Act of 1940. However, each Fund intends to meet federal tax
requirements for qualification as a regulated investment company.

Each Fund intends to remain fully invested in municipal obligations (obligations
issued by or on behalf of a state, its political subdivisions, agencies, and
instrumentalities). As a fundamental policy, each Fund will invest at least 80%
of its total assets in obligations with interest exempt from regular federal
income tax, including the alternative minimum tax.

In addition, each Fund will invest at least 65% of its net assets in Florida
municipal obligations (obligations issued by or on behalf of Florida, its
political subdivisions, agencies, and instrumentalities, or U.S. possessions or
territories such as Puerto Rico). The remaining 35% of net assets may be
invested in (i) obligations issued by other states and their political
subdivisions and (ii) U.S. government securities. Under exceptional market or
economic conditions, each Fund may invest more than 35% of its net assets in
these securities.


10
<PAGE>

Each Fund is authorized under normal conditions to invest as much as 100% of its
net assets in municipal obligations for which the interest is a tax preference
item for purposes of the federal alternative minimum tax (AMT). If you are or
become subject to the AMT, a portion of your income distributions that are
exempt from the regular federal income tax may not be exempt from the AMT.
Interest from AMT bonds is considered to be exempt from federal income tax for
purposes of the 80% policy noted above.

As discussed more fully on page 39, a Fund may need to sell certain investments
near the end of each calendar year so that on January 1 of each year, its
portfolio consists only of investments that are exempt from the Florida
intangibles tax. As a result, a Fund could incur additional costs or taxable
income or gains.

BENHAM NATIONAL TAX-FREE FUNDS

Each Fund is a "diversified company" as defined in the Investment Company Act of
1940. This means that, with respect to 75% of its total assets, each Fund will
not invest more than 5% of its total assets in the securities of a single
issuer.  This policy is fundamental.

Each Fund intends to remain fully invested in municipal obligations, although
for temporary defensive purposes, each may invest a portion of its assets in
U.S. government securities, the interest income on which is subject to federal
income tax. Each Fund may invest up to 20% of its assets in securities issued by
U.S. territories or possessions, such as Puerto Rico, provided that the interest
on these securities is exempt from the regular federal income tax.

Fund-specific investment policies are set forth in the following pages.

In selecting investments for the MONEY MARKET FUNDS, BMC adheres to regulatory
guidelines concerning the quality and maturity of money market fund investments
as well as to internal guidelines designed to minimize credit risk. In
particular, each Fund

(1)  Buys only U.S. dollar-denominated obligations with remaining maturities of
     13 months or less (and variable- and floating-rate obligations with demand

- -------------------
[information in right margin of page]
The Florida and National Intermediate-Term Funds invest primarily in municipal
obligations with maturities of four or more years.
- -------------------

                                                                              11
<PAGE>

     features that effectively shorten their maturities to 13 months or less);

(2)  Maintains a dollar-weighted average maturity of 60 days or less (90 days or
     less for Florida Money Market Fund); and

(3)  Restricts its investments to high-quality obligations determined by BMC,
     pursuant to procedures established by the board of trustees, to present
     minimal credit risks.

To be considered high quality, an obligation must be

(1)  A U.S. government obligation;

(2)  Rated, or issued by an issuer rated with respect to a class of comparable
     short-term debt obligations, in one of the two highest rating categories
     for short-term obligations by at least two rating agencies (or one if only
     one has rated the obligation); or

(3)  An unrated obligation judged by BMC, pursuant to guidelines established by 
     the board of trustees, to be of comparable quality.

The VARIABLE-PRICE FUNDS have similar policies governing the quality of
securities in which they may invest, as described below. The Funds differ in
their maturity criteria as follows:

The FLORIDA INTERMEDIATE-TERM FUND invests primarily in intermediate-term
Florida municipal obligations with maturities of four or more years. The
weighted average portfolio maturity is five to ten years.

The NATIONAL INTERMEDIATE-TERM FUND invests primarily in municipal obligations
with maturities of four or more years. Its weighted average maturity ranges from
five to ten years.

The NATIONAL LONG-TERM FUND invests primarily in long-term municipal
obligations. It maintains a weighted average maturity of ten or more years.

In terms of quality, each Variable-Price Fund restricts its investments to

(1)  Municipal bonds rated, when acquired, within the three highest (four
     highest for Florida Intermediate-Term Fund) categories designated by a
     rating agency;


12
<PAGE>

(2)  Municipal notes (including variable-rate demand obligations) and tax-exempt
     commercial paper rated, when acquired, within the two highest categories
     designated by a rating agency; and

(3)  Unrated obligations judged by BMC, under the direction of the board of 
     trustees, to be of comparable quality.

SUITABILITY

The Florida Municipal Funds are designed for individuals in upper tax brackets
seeking income free from regular federal income tax, although the Funds may
generate some taxable income. The Funds also provide an investment that is
intended to be exempt from the Florida intangibles tax. Because of this emphasis
on tax-exempt income, the Funds by themselves do not constitute balanced
investment plans.

The Money Market Funds may be appropriate for investors seeking share price
stability who can accept the lower yields that short-term obligations typically
provide. To offer investors the potential for higher yields, the Florida and
National Intermediate-Term Funds invest in obligations with longer maturities.
The National Long-Term Fund generally offers the highest current yields but, of
all the Funds, is also the most susceptible to share price fluctuations.

Each Fund described in this Prospectus offers a range of potential for income
and total return based on its maturity criteria. The market value of the
investments of each Fund will change over time in response to a number of
factors, which are summarized in the following paragraphs.

Interest Rate Risk: One feature the Funds have in common is their susceptibility
to changing interest rates. For both Money Market Funds, interest rate changes
affect the level of income the Funds generate for shareholders. For the
Variable-Price Funds, changing interest rates affect not only the level of
income the Funds generate for shareholders, but their share prices as well. In
general, when interest rates rise, the Variable-Price Funds' share prices
decline; when interest rates decline, their share prices rise.

This pattern is due to the time value of money. A bond's worth is determined by
the present value of its future

                                                                              13
<PAGE>

cash flows. Consequently, changing interest rates have a greater effect on the 
present value of a long-term bond than a short-term bond.

Credit Risk: In selecting investments for each Fund, BMC carefully considers the
creditworthiness of parties relied upon for the timely payment of interest and
their reliability for the timely payment of interest and repayment of principal.

In many cases, these parties include not only the issuer of the obligation but a
bank or other financial intermediary who offers a letter of credit or other form
of guarantee on the obligation.

Liquidity Risk: Securities ratings reflect the opinions of the rating agencies
that issue them and are not absolute standards of quality. Because of the cost
of obtaining credit ratings, some issuers forego them. Under the direction of
the board of trustees, BMC may buy unrated bonds for the Funds if these
securities are judged to be of a quality consistent with the Funds' investment
policies. Similarly, on behalf of the Variable-Price Funds, BMC may purchase
securities whose ratings are not consistent with the Funds' rating criteria but
which BMC judges under the direction of the board of trustees to present credit
risks consistent with the Funds' quality standards.

The Florida Intermediate-Term Fund may invest up to 15% of its net assets in
unrated securities. Each of the other Funds described in this Prospectus may
invest up to 10% of its assets in unrated securities. Unrated securities may be
less liquid than rated securities.

The Florida Intermediate-Term Fund may invest in securities rated Baa or BBB-
(the lowest investment grade category). Such securities are medium-grade
investment obligations that may have speculative characteristics. Changes in
economic conditions or other circumstances are more likely to lead to a weakened
capacity for such obligations to make principal and interest payments.

Concentration Risk: Each of the Funds described in this Prospectus may invest
25% or more of its assets in obligations that generate income from similar types
of projects (in particular, projects in health care, electric, water/sewer,
education, and transportation). Political or economic developments affecting a
single issuer or industry or similar types of projects may have a significant
effect on Fund performance.

14
<PAGE>

Call Risk: Many municipal obligations are issued with a call feature (features
include a date on which the issuer has reserved the right to redeem the
obligation prior to maturity). An obligation may be called for redemption before
BMC would otherwise choose to eliminate it from a Fund's holdings. A call may
also reduce an obligation's yield to maturity.

FLORIDA OBLIGATIONS (FLORIDA MUNICIPAL FUNDS ONLY)

Because the Florida Municipal Funds invest primarily in Florida municipal
securities, Fund yields and share prices are affected by political and economic
conditions and developments within the state of Florida. The following summary
is derived from independent municipal credit reports but has not been
independently verified by the Funds and does not purport to be a complete
description of the conditions and developments in Florida that may affect the
Funds.

Historically, the Florida economy has been dependent upon agriculture and
seasonal tourism. These industries are vulnerable to widespread crop failures,
severe weather conditions and other agriculture-related problems, and trends and
difficulties in the tourism industry. In recent years, the economy has broadened
into a service and trade economy with substantial insurance, banking, and export
participation as well as a tourism industry that operates less seasonally.

Population growth was significant in the 1980s but is expected to continue at
reduced rates. The retiree component of the population is expected to continue
to be a major factor. The population growth and expanding economy have brought
pressures for more infrastructure, educational facilities, and other needs.
Therefore, construction is very important to the Florida economy but is
vulnerable to declines in economic and population growth and has been weak in
recent years.

In August 1992, Hurricane Andrew struck southern Florida, with consequent
hurricane damage estimated to be $20-30 billion, about $10.2 billion of which
was insured. Although the state and federal governments have pledged funds to
help rebuild the area, the impact of this event on the fiscal resources of the
state and on local governments is difficult to assess.


                                                                              15
<PAGE>

Florida is heavily dependent upon sales tax revenues, making the state's general
fund vulnerable to recession and presenting difficulties in expanding the tax
base in an economy increasingly geared to services. This dependence on sales tax
has resulted in budgetary shortfalls in the past; Florida has reacted to
preserve an adequate financial position primarily through expenditure reductions
and by doubling the intangibles tax.

For further information about the risks associated with investing in Florida
obligations, please see the Florida Municipal Funds' Statement of Additional
Information.

MUNICIPAL SECURITIES

Municipal securities are issued to raise money for a variety of public purposes,
including general financing for state and local governments as well as financing
for specific projects and public facilities. Municipal securities may be backed
by the full taxing power of a municipality, the revenues from a specific
project, or the credit of a private organization. The following pages provide a
brief description of some securities the Funds may buy. The Funds are not
limited by this discussion, and they may buy other types of securities and enter
into other types of transactions that meet their respective quality, maturity,
and liquidity requirements.

MUNICIPAL NOTES typically have maturities of 13 months or less and are used to
provide short-term capital or to meet cash flow needs.

GENERAL OBLIGATION BONDS are backed by the taxing power of the issuer. REVENUE
BONDS are backed by the revenues derived from a specific project, system, or
facility. Industrial development bonds are a type of revenue bond backed by the
credit of a private issuer.

VARIABLE- AND FLOATING-RATE DEMAND OBLIGATIONS have interest rate adjustment
formulas designed to stabilize their market values. These obligations normally
have maturities in excess of one year but carry demand features permitting the
holders to demand repayment of principal at any time or at specified intervals.
With respect to the Money Market Funds, such intervals may not exceed 13 months.


16
<PAGE>

TENDER OPTION BONDS are created by combining an intermediate- or long-term
fixed-rate tax-exempt bond with a tender agreement that gives the holder the
option to tender the bond at face value. Tender option bonds purchased by the
Funds are structured with rates that are reset weekly or at other regular
intervals.

A sponsor may terminate a tender option agreement if, for example, the issuer of
the underlying bond defaults on interest payments, or the underlying bond is
downgraded or becomes taxable. Under such circumstances, a Fund might then own a
bond that does not meet its quality or maturity criteria.

BMC monitors the credit quality of bonds underlying the Funds' tender option
bond holdings and will sell or put back a tender option bond if the rating on
the underlying bond falls below the second-highest rating designated by a rating
agency. In addition, each Fund limits its investments in tender option bonds to
15% of net assets.

MUNICIPAL LEASE OBLIGATIONS are issued by state and local governments to acquire
land and a wide variety of equipment and facilities. These obligations typically
are not fully backed by the issuing municipality's ability to assess taxes to
meet its debt obligations. If the state or local government does not make
appropriations for the following year's lease payments, the lease may terminate,
with the possibility of default on the lease obligation and loss to investors.

Prior to purchasing a municipal lease obligation (or a participation interest in
such obligations) and on a regular basis thereafter, pursuant to guidelines
adopted by the board of trustees, BMC evaluates the credit quality and liquidity
of the obligation. In making this evaluation, BMC considers various credit
factors, such as the necessity of the project; the issuer's credit quality,
future borrowing plans, and sources of revenue pledged for lease repayment;
general economic conditions in the region where the security is issued;
liquidity indicators such as dealer activity; and with regard to unrated
obligations, the likelihood such lease will not be cancelled.

<PAGE>

ZERO-COUPON MUNICIPAL SECURITIES do not make regular interest payments. Instead,
they are sold at a deep discount to their face value. In calculating daily
dividends, the Funds take into account, as income, a portion of the difference
between these securities' purchase prices and face values. Because zero-coupon
securities do not pay current income, their prices can be very volatile when
interest rates change.

The Variable-Price Funds may invest in INVERSE FLOATERS to generate higher
tax-exempt yields than are offered by other instruments. Inverse floaters bear
interest rates that move inversely to market interest rates. Generally, the
interest rate on the inverse floater is computed as the difference between an
above-market fixed rate of interest and a floating rate determined by reference
to a market-based or bond-specific interest rate.

Since inverse floaters are long-term bonds, the value of these securities may be
volatile when market interest rates change. In addition, there is no guarantee
that BMC will find a ready buyer for inverse floaters. The Money Market Funds
may not invest in inverse floaters.

AMT BONDS (FLORIDA MUNICIPAL FUNDS ONLY) typically are tax-exempt "private
activity" bonds issued after August 7, 1986, whose proceeds are directed at
least in part to a private, for-profit organization. Although the interest
income from AMT bonds is exempt from regular federal income tax, that income is
a tax preference item for purposes of the AMT.

In addition, corporate investors should note that all income from a Fund may be
part of an adjustment to AMT under Internal Revenue Code Section 55 and the
environmental tax under Internal Revenue Code Section 59A. The AMT is a special
separate tax that applies to certain taxpayers who have certain adjustments to
income or tax preference items. The Florida Municipal Funds are authorized to
invest as much as 100% of their assets in AMT bonds.

INVESTMENT PRACTICES

WHEN-ISSUED AND FORWARD-COMMITMENT AGREEMENTS

When-issued securities and forward-commitment agreements fix a security's price
and yield for future payment and delivery. The market value of a security may
change during this period, or a party to the agreement may fail to pay for the
security. Either of these situations could affect the market value of a Fund's
assets.

FUTURES AND OPTIONS CONTRACTS (VARIABLE-PRICE FUNDS ONLY)

The Variable-Price Funds may use futures and options transactions to maintain
cash reserves while remaining fully invested, to facilitate trading, to reduce
transaction costs, or to pursue higher investment returns when a futures
contract is priced more attractively than its underlying security or index.

Some futures contract strategies present a substantial risk of loss, due to both
the low margin deposits required and the high degree of leverage involved in
futures pricing. A relatively small movement in a futures contract may result in
immediate, substantial gains or losses to the contract holder. Gains from
futures and options transactions are not exempt from federal income tax when
distributed to shareholders.

RESTRICTED AND ILLIQUID SECURITIES

A portion of each Fund's assets may be invested in obligations that are subject
to restrictions on resale (restricted securities). Certain restricted securities
may be deemed liquid pursuant to guidelines established by the board of
trustees. No more than 10% (15% for Florida Intermediate-Term Fund) of a Fund's
net assets may be invested in illiquid securities.

CASH MANAGEMENT (VARIABLE-PRICE FUNDS ONLY)

For cash management purposes, each of the Variable-Price Funds may invest up to
an aggregate total of 5% of its assets in any Benham money market fund advised
by BMC, provided that the investment is consistent with the Fund's investment
policies and restrictions. 

                                                                              19

OTHER INVESTMENT MANAGEMENT TECHNIQUES 

BMC may buy other types of securities or employ other portfolio management
techniques on behalf of the Funds. When SEC guidelines require it to do so, a
Fund will set aside cash or appropriate liquid assets in a segregated account to
cover portfolio obligations. The Funds are subject to a number of fundamental
investment restrictions, which are set forth in the Funds' respective Statements
of Additional Information.

PERFORMANCE

Mutual Fund performance is commonly measured as yield or total return. It is
based on historical fund performance and may be quoted in advertising and sales
literature. Past performance is no guarantee of future results.

The MONEY MARKET FUNDS' yield is based on the income generated by investments in
the Funds over a seven-day period, expressed as an annual percentage rate. The
Funds' EFFECTIVE YIELDS are calculated similarly, although these figures will be
slightly higher than the Funds' yields because they assume that income earned
from the Funds' investments is reinvested.

YIELD CALCULATIONS FOR VARIABLE-PRICE FUNDS show the rate of income a Fund earns
on its investments as a percentage of its share price. To calculate yield, each
Variable-Price Fund takes the interest it earned from its portfolio of
investments for a 30-day period (net of expenses), divides it by the average
number of shares entitled to receive dividends, and expresses the result as an
annualized percentage rate based on the Fund's share price at the end of the
30-day period.

EACH FUND MAY QUOTE TAX-EQUIVALENT YIELDS, which show the taxable yields an
investor would have to earn before taxes to equal the Fund's tax-free yields.

For the Florida Municipal Funds, the tax-equivalent yield is based on each
Fund's current tax-free yield, your federal income tax bracket, and the Florida
intangibles tax applicable to a taxable investment. The formula is:

    Fund's Tax-Free Yield           Florida         Your Tax-
 --------------------------   +   Intangibles  =   Equivalent
 100% - Federal Tax Bracket        Tax Rate          Yield  
                                    

20
<PAGE>

For instance, if you are a Florida resident in a federal tax bracket of 36%, are
subject to the intangibles tax rate of two mills, and the Fund's tax-free yield
is 5%, your calculation would be as follows:

  .05    
- -------   +  .002  = .078   + .002   = .080  =  8.0%
1 - .36

In this example, your return on a tax-free investment yielding 5% would be
higher than on a taxable investment with comparable quality and maturity
characteristics yielding less than 8.00%.

You can calculate your tax-equivalent yield for a NATIONAL TAX-FREE FUND (taking
into account only federal income taxes and not any applicable state taxes) using
the following equation:

        Fund's Tax-Free Yield        
   -------------------------------    =       Your Tax- 
   100% - Your Federal Tax Bracket        Equivalent Yield

For example, if you were in the 36% federal income tax bracket, and the fund's
federally tax-free yield was 5%, your calculation would be as follows:

        .05      =    .078    =    7.8%
      -------
      1 - .36

In this example, your return on a federally tax-free investment yielding 5%
would be higher than on a taxable investment with comparable quality and
maturity characteristics yielding less than 7.8%.

If only a portion of a Fund's income was tax-exempt, only that portion would be
adjusted in the calculation.

TOTAL RETURN represents the Fund's changes over a specified time period,
assuming reinvestment of dividends and capital gains, if any. CUMULATIVE TOTAL
RETURN illustrates the Fund's actual performance over a stated period of time.
AVERAGE ANNUAL TOTAL RETURN is a hypothetical rate of return that illustrates
the annually compounded return that would have produced the same cumulative
total return if the Fund's performance had been constant over a entire period.
Average annual total returns smooth out variations in the Fund's performance;
they are not the same as year-by-year results.

Each Fund may quote tax-equivalent yields, which show the taxable yields an
investor would have to earn before taxes to equal the Fund's tax-free yields.

Shares may be purchased and redeemed without any sales charge, commission,
redemption fee, 12b-1 fee, or contingent deferred sales load.

Performance data and a discussion of factors that affected performance during

SHARE PRICE

The price of your shares is their net asset value next determined after receipt
of your instruction to purchase, convert or redeem. Net asset value is
determined by calculating the total value of a Fund's assets, deducting total
liabilities and dividing the result by the number of shares outstanding. Net
asset value is determined on each day that the New York Stock Exchange is open.

Investments and requests to redeem shares will receive the share price next
determined after receipt by Benham of the investment or redemption request. For
example, investments and requests to redeem shares received by Benham before the
close of business on the New York Stock Exchange are effective on, and will
receive the price determined, that day as of the close of the Exchange.
Redemption requests received thereafter are effective on, and receive the price
determined as of the close of the Exchange on, the next day the Exchange is
open.

22
<PAGE>

Investments are considered received only when your check or wired funds are
received by Benham. Wired funds are considered received on the day they are
deposited in Benham's bank account if they are deposited before the close of
business on the Exchange, usually 1:00 p.m. Pacific Time.

Investments by telephone pursuant to your prior authorization to Benham to draw
on your bank account are considered received at the time of your telephone call.

Investment and transaction instructions received by Benham on any business day
by mail at its office prior to the close of business on the Exchange, usually
1:00 p.m. Pacific Time, will receive that day's price. Investments and
instructions received after that time, will receive the price determined on the
next business day.

SECURITIES HELD BY THE MONEY MARKET FUNDS are valued at amortized cost. This
method involves initially valuing a security at its cost and thereafter assuming
a constant amortization to maturity of any discount or premium paid at the time
of purchase, rather than determining the security's market value from day to
day.

MOST SECURITIES HELD BY THE VARIABLE-PRICE FUNDS are priced at fair market value
using prices obtained daily from an independent pricing service. Other
securities are priced at fair market value as determined in good faith pursuant
to guidelines established by the Funds' board of trustees.


                                                                              23

                 If you do not have a preprinted investment slip, send your
                 check with separate written instructions indicating the fund
                 name and the account number. If the payee information provided

PROCESSING YOUR PURCHASE

Shares will be purchased at the next NAV calculated after your investment is
received and accepted by Benham or an authorized subtransfer agent. Investments
received and accepted before the close of business day of the NYSE, normally
1:00 p.m. Pacific Time, will be included in your account balance the same day.
After 1:00 p.m. Pacific Time, they will be credited the following business day.
The Funds reserve the right to refuse any investment.

TELEPHONE TRANSACTIONS

Shareholders may order certain transactions (e.g., exchanges, wires, some types
of redemptions) by telephone. This privilege is granted to Benham fund
shareholders automatically; you need not specifically request this service, and
you may not specifically decline it.

The Benham Group will not be liable for losses resulting from unauthorized or
fraudulent instructions if it follows procedures designed to verify the caller's
identity. BMC will request personal identification, record telephone calls, and
send confirmation statements for every telephone transaction to the
shareholder's record address. The Funds reserve the right to revise or terminate
telephone transaction privileges at any time.

CONFIRMATION AND QUARTERLY STATEMENTS

All transactions are summarized on quarterly account statements. In addition,
for every transaction that you request, a confirmation statement will be mailed
to your record address. Please review these statements carefully. If you believe
we have processed the transaction you requested incorrectly, please notify us as
soon as possible. If you fail to notify us of an error with reasonable
promptness, i.e., within 30 days of the date of your confirmation statement, we
will deem you to have ratified the transaction.


                                                                              27

The free exchange privilege is a convenient way to buy shares in other Benham
funds if your investment goals change.
- ------------------- 

SHAREHOLDER SERVICES

EXCHANGE PRIVILEGE

You may exchange your shares for shares of equivalent value in any other Benham
fund registered for sale in your state. An exchange request will be processed
the same day if it is received before the funds' NAVs are calculated (one hour
prior to the close of the NYSE, usually 12:00 noon Pacific Time, for Benham
Target Maturities Trust, and at the close of the NYSE, usually 1:00 p.m. Pacific
Time, for all other Benham funds).

The Benham Group discourages trading in response to short-term market
fluctuations. Such activity may encumber BMC's ability to invest the funds'
assets in accordance with their respective investment objectives and policies
and may be disadvantageous to other shareholders. In addition, an exchange out
of variable-price funds generally will generate taxable gains or losses to the
shareholder. More than six exchanges per calendar year out of a variable-price
fund may be deemed an abuse of the exchange privilege. For purposes of
determining the number of exchanges made, accounts under common ownership or
control will be aggregated.

Currently there are no restrictions on exchanges out of either Money Market
Fund. However, each Benham fund reserves the right to modify or revoke the
exchange privilege of any shareholder or to limit or reject any exchange.
Although each fund will attempt to give shareholders prior notice whenever it is
reasonably able to do so, it may impose these restrictions at any time.

OPEN ORDER SERVICE

The Benham Group's Open Order Service allows you to designate a price at which
to buy or sell shares of a variable-price fund by exchange from a money market
fund. To place a "buy" order, you designate a purchase price that is equal to or
lower than the current NAV. To place a "sell" order, designate a sales price
that is equal to or higher than the current NAV. If the designated price is met
within 90 calendar days, we will automatically execute your order. If you are
buying shares of a variable-price fund, we will exchange money from your money
market account to purchase them. If you are selling shares of a variable-price
fund, we will transfer 


28
<PAGE>

the proceeds of that sale to your money market account. If you do not have a
money market account, we will open one for you when we execute your Open Order.

If the fund you have selected deducts a distribution from its share price, your
order price will be adjusted accordingly so that the distribution does not
inadvertently trigger an Open Order transaction on your behalf. If you close or
reregister the account from which shares are to be redeemed, your Open Order
will be cancelled. Because of their time-sensitive nature, Open Order
transactions may be made by telephone or in person. These transactions are
subject to the exchange limitations described in each fund's prospectus, except
that all orders and cancellations received before 12:00 p.m. Pacific Time are
effective the same day. After 12:00 p.m. Pacific Time, they are effective the
following business day.

If you hold shares in certificate form, redemption requests must be accompanied
by properly endorsed certificates.

If you want to keep your account open, please maintain a balance of shares worth
at least $1,000. If your account balance falls to less than $1,000 due to
redemption, your account may be closed, but not without at least 30 days' notice
and an opportunity to increase your account balance to the $1,000 minimum. Your
shares will be redeemed at the NAV calculated on the day your account is closed.
Proceeds will be mailed to the record address.

This policy applies to Benham's Individual Retirement Accounts (IRAs), excluding
SEP-IRAs, except that shareholders will receive at least 120 days' written
notice and an opportunity to increase their account balance before their
accounts are closed. Investors wishing to open a Benham-sponsored retirement
account should see pages 34 and 35 for details.

UNCASHED CHECKS

We may reinvest at a Fund's current NAV any distribution or redemption check
that remains uncashed for six months. Until we receive instructions to the
contrary, subsequent distributions will be reinvested in the original account.
Uncashed redemption checks may be reinvested in an identically registered
account.

ABOUT BENHAM-SPONSORED RETIREMENT PLANS

Retirement plans offer investors a number of benefits, including the chance to
reduce current taxable income and to take advantage of tax-deferred compounding.
Retirement plan accounts require a special application; please let our
Shareholder Relations Department know if you want to establish this type of
account. We suggest that you consult your tax advisor before establishing a
retirement plan account. The minimum account balance for all Benham Individual
Retirement Accounts (IRAs), excluding SEP-IRAs, is $1,000. If your balance falls
below the $1,000 per fund account (continued on the next page)

[information in left margin of page]
Each January you will be informed of the tax status of dividends and capital
gain distributions for the previous year.
- -------------------

DISTRIBUTIONS AND TAXES

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

MONEY MARKET FUNDS: Dividends are declared and credited daily and distributed as
of the last business day of the month.

VARIABLE-PRICE FUND: Dividends are declared daily, accrued throughout the month,
and distributed on the last business day of the month.

ALL FUNDS: Net capital gains, if any, are declared and distributed once a year
in December.

DISTRIBUTION OPTIONS. You may choose to receive dividends and capital gain
distributions in cash or to reinvest them in additional shares. (See "Directed
Dividends" on page 29 for further information.) Please indicate your choice on
your account application or contact our Shareholder Relations Department. See
page 31 for a description of our policy regarding uncashed checks.

TAXES

Each Fund intends to qualify annually as a regulated investment company under
Subchapter M of the Internal Revenue Code of 1986 (Code), as amended, by
distributing all or substantially all of its net investment income and net
realized capital gains to shareholders each year.

Interest earned by a Fund from municipal and other tax-exempt obligations
generally is exempt from the regular federal income tax. Each Fund intends to
invest a sufficient portion of its assets in state and municipal obligations so
that it will qualify to pay "exempt-interest dividends" to shareholders. Such
exempt-interest dividends are generally excludable from a shareholder's gross
income for federal tax purposes. If a Fund earned federally taxable income from
any of its investments, the income would be distributed to shareholders as a
taxable dividend.

Exempt-interest dividends of a Fund, although exempt from regular federal income
tax, are includable in the tax base for determining the extent to which social
security or railroad retirement benefits will be subject to federal income tax.


36
<PAGE>

Distributions from net short-term capital gains and all or a portion of gains
realized upon the disposition of market discount bonds are federally taxable as
ordinary income. Long-term capital gain distributions designated as capital gain
dividends are federally taxable as long-term capital gains, regardless of how
long you have held your shares. Distributions generally are subject to the same
tax treatment, whether they are received in cash or in additional shares.
Distributions declared to record shareholders in October, November, or December
and paid in January of the following year are treated as if paid on December 31.

You may realize a taxable gain or loss when you redeem (sell) or exchange shares
of a Variable-Price Fund. For most types of accounts, proceeds from your
redemption transactions will be reported to the IRS annually. However, because
the tax treatment depends on your purchase price and your personal tax
situation, you should keep your regular account statements to use in determining
your taxes.

If you hold Fund shares for six months or less, the deduction of any loss
realized upon redemption is disallowed to the extent that you received
"exempt-interest dividends" on those shares. All shareholders are required to
report the receipt of dividends and distributions, including exempt-interest
dividends, on their federal income tax returns.

Shareholders should be aware that redeeming shares of a Fund after tax-exempt
interest income has been accrued by a Fund but before that income has been
distributed as a dividend may be disadvantageous. Any gain on such redemption
will be taxable, even though the gain may be attributable in part to the accrued
tax-exempt interest that might have qualified as an exempt-interest dividend if
distributed as a dividend rather than as redemption proceeds.

BUYING A DIVIDEND. The timing of your investment could have undesirable tax
consequences. If you open a new account or buy more shares for your current
account just before the day a dividend or distribution is reflected in your
Fund's share price, you will receive a portion of your investment back as a
taxable dividend or distribution.


                                                                              37
<PAGE>

Deductions for interest expense incurred (or deemed to be incurred) to acquire
or carry shares of a Fund may be subject to limitations that reduce or eliminate
the deductions.

Opinions relating to the validity of municipal securities and the exemptions of
interest thereon from federal income tax are rendered by bond counsel to the
issuers. The Funds, BMC, and the Funds' counsel rely on the opinion of bond
counsel, and do not undertake any independent investigation of proceedings
relating to the issuance of state or municipal securities. The Funds may invest
in various instruments that are not traditional state and local obligations and
that are believed to generate interest excludable from taxable income under Code
Section 103, including, but not limited to, municipal lease obligations and
inverse floaters. Although the Funds may invest in these instruments, they
cannot guarantee the tax-exempt status of the income earned thereon or from any
other investment.

BACKUP WITHHOLDING. The Funds are required by federal law to withhold 31% of
reportable dividends and capital gain distributions (as well as redemptions from
Variable-Price Funds) payable to shareholders who have not complied with IRS
regulations. These regulations require you to certify on your account
application or on IRS Form W-9 that your social security or taxpayer
identification number (TIN) is correct and that you are not subject to backup
withholding from previous underreporting to the IRS, or that you are exempt from
backup withholding.

The Benham Group may refuse to sell shares to investors who have not complied
with this requirement, either before or at the time of purchase. Until we
receive your certified tax certification, we may redeem your shares in the Funds
at any time.

AMT LIABILITY. To the extent that the Florida Municipal Funds invest in
municipal obligations (private activity bonds) whose interest is treated as a
tax-preference item in calculating AMT liability, shareholders who calculate AMT
liability will be required to include a portion of the Florida Municipal Fund's
dividends as a tax-preference 

38
<PAGE>

item in making this calculation. In addition, corporate shareholders may be
required to include all Fund dividends and distributions by the Funds in an
adjustment to alternative minimum taxable income for purposes of the AMT and the
environmental tax imposed under Code Sections 55 and 59A, respectively.

Florida currently does not have a personal income tax, so Fund dividends and
distributions earned by Florida residents will not be subject to such a tax.
However, if you are domiciled outside of Florida, Fund dividends and
distributions may be subject to your state's taxes. Fund dividends and
distributions earned by corporate shareholders that are subject to the Florida
corporate income tax may be taxable by Florida; these shareholders should
consult their tax advisors regarding the application of the Florida corporate
income tax to Fund dividends and distributions.

The Florida Municipal Funds may apply for rulings from the Florida Department of
Revenue (FDR) to the effect that shares of a Fund be exempt from the Florida
intangibles tax each year if the Fund's portfolio of investments on January 1 of
that year consists of qualifying investments.

Investments exempt from the Florida intangibles tax include but are not limited
to (i) notes, bonds and other obligations issued by Florida or its
municipalities, counties, and other taxing districts and (ii) notes, bonds, and
other obligations issued by the U.S. government and its agencies. Obligations
issued by the governments of Puerto Rico, Guam, and the Virgin Islands are also
exempt if permitted by ruling.

If a Florida Municipal Fund's portfolio of investments on January 1 of each year
includes investments that are not exempt from the Florida intangibles tax, the
Fund's shares could be subject to the Florida intangibles tax. The Funds intend
that on January 1 of each year, each Fund's portfolio of investments will
consist solely of investments exempt from the Florida intangibles tax.
Shareholders who are domiciled outside of Florida may be subject to income,
personal property, intangibles, or similar taxes in their respective states.

                                                                              39

MANAGEMENT INFORMATION

ABOUT THE TRUST

Benham Municipal Trust is a registered open-end management investment company
that was organized as a Massachusetts business trust on May 1, 1984. (The Trust
was formerly known as "Benham National Tax-Free Trust".) Five of the Trust's
eight series are described in this Prospectus; additional series may be created
from time to time.

A board of trustees oversees the Funds' activities and is responsible for
protecting shareholders' interests in the Funds. The Trust is neither required
nor expected to hold annual meetings, although special meetings may be called
for purposes such as electing or removing trustees or amending a series'
advisory agreement or investment policies. The number of votes you are entitled
to is based upon the dollar value of your investment. Each series votes
separately on matters that pertain to it exclusively. Voting rights are not
cumulative.

THE BENHAM GROUP

Benham Management Corporation (BMC) is investment advisor to the funds in The
Benham Group, which currently constitute more than $11 billion in assets. BMC,
incorporated in California in 1971, became a wholly owned subsidiary of
Twentieth Century Companies, Inc. (TCC), a Delaware corporation, on June 1,
1995, upon the merger of Benham Management International, Inc., BMC's former
parent, into TCC. TCC is a holding company that owns the operating companies
that provide the investment management, transfer agency, shareholder service,
and other services for the Twentieth Century family of funds, which now includes
the Benham Group. The combined company offers 62 mutual funds and has combined
assets of more than $41 billion.

Benham Management Corporation (BMC) supervises and manages the investment
portfolios of The Benham Group and directs the purchase and sale of its
investment securities. BMC utilizes teams of portfolio managers, assistant
portfolio managers and analysts acting together to manage the assets of the
funds. The teams meet regularly to review portfolio holdings and to discuss
purchase and sale activity. The teams adjust 

40
<PAGE>

holdings in the funds' portfolios as deemed appropriate in pursuit of the Funds'
investment objectives. Individual portfolio manager members of the team may also
adjust portfolio holdings of the funds as necessary between team meetings.

Mr. G. David MacEwen, Senior Portfolio Manager, has primary responsibility for
the day-to-day operations of all series of the Trust. He also manages the
following Benham California Tax-Free and Municipal Funds: Tax-Free Short-Term
Fund, Tax-Free Intermediate-Term Fund, Tax-Free Long-Term Fund, and Tax-Free
Insured Fund. Before joining BMC in 1991, Mr. MacEwen was Vice
President-Municipal Portfolio Manager at Provident Institutional Management
Corporation in Wilmington, Delaware (1986 to 1991).

ADVISORY AND SERVICE FEES

For investment advice and portfolio management services, each Fund pays BMC a
monthly investment advisory fee equal to its pro rata share of the dollar amount
derived from applying the Trust's average daily net assets to an investment
advisory fee schedule. The investment advisory fee rate cannot exceed .50% of
average daily net assets, and it drops to a marginal rate of .19% of average
daily net assets as Trust assets increase.

The following table illustrates each Fund's investment advisory fees for the
fiscal year ended May 31, 1995, as a percentage of the Fund's average daily net
assets and as a dollar amount per $1,000 of the Fund's average daily net assets.

National Long-Term Fund                    .33%      $3.30

*Net of expense limitation agreement, as described on pages 4 and 42.

To avoid duplicative investment advisory fees, the variable-price funds do not
pay BMC investment advisory fees with respect to assets invested in shares of a
money market fund advised by BMC.

The administrative fee rate ranges from .11% to .08% of average daily net
assets, dropping as Benham Group assets increase. For transfer agent services,
each Fund pays BFS a monthly fee for each shareholder account maintained and for
each shareholder transaction executed during that month.

INVESTMENT POLICIES AND TECHNIQUES

The following pages provide a more detailed description of the securities and
investment practices identified in the Prospectus. Unless otherwise noted, the
policies described in this Statement of Additional Information are not
fundamental and may be changed by the board of trustees.

MUNICIPAL NOTES

Municipal notes are issued by state and local governments or government entities
to provide short-term capital or to meet cash flow needs.

TAX ANTICIPATION NOTES (TANS) are issued in anticipation of seasonal tax
revenues, such as ad valorem property, income, sales, use, and business taxes,
and are payable from these future taxes. Tax anticipation notes usually are
general obligations of the issuer. General obligations are secured by the
issuer's pledge of its full faith and credit (i.e., taxing power) for the
payment of principal and interest.

REVENUE ANTICIPATION NOTES (RANS) are issued with the expectation that receipt
of future revenues, such as federal revenue sharing or state aid payments, will
be used to repay the notes. Typically, these notes also constitute general
obligations of the issuer.

BOND ANTICIPATION NOTES (BANS) are issued to provide interim financing until
long-term financing can be arranged. In most cases, the long-term bonds provide
the money for repayment of the notes.

TAX-EXEMPT COMMERCIAL PAPER is an obligation with a stated maturity of 365 days
or less issued to finance seasonal cash flow needs or to provide short-term
financing in anticipation of longer-term financing.

MUNICIPAL BONDS

Municipal bonds, which generally have maturities of more than one year when
issued, are designed to meet longer-term capital needs. These securities have
two principal classifications: general obligation bonds and revenue bonds.

GENERAL OBLIGATION (GO) BONDS are issued by states, counties, cities, towns, and
regional districts to fund a variety of public projects, including construction
of and improvements to schools, highways, and water and sewer systems. General
obligation bonds are backed by the issuer's full faith and credit based on its
ability to levy taxes for the timely payment of interest and repayment of
principal, although such levies may be constitutionally or statutorily limited
as to rate or amount.

REVENUE BONDS are not backed by an issuer's taxing authority; rather, interest
and principal are secured by the net revenues from a project or facility.
Revenue bonds are issued to finance a variety of capital projects, including
construction or refurbishment of utility and waste disposal systems, highways,
bridges, tunnels, air and sea port facilities, schools, and hospitals. Many
revenue bond issuers provide additional security in the form of a debt service
reserve fund that may be used to make payments of interest and repayments of
principal on the issuer's obligations. Some revenue bond financings are further
protected by a state's assurance (without obligation) that it will make up
deficiencies in the debt-service reserve fund.

INDUSTRIAL DEVELOPMENT BONDS (IDBs), a type of revenue bond, are issued by or on
behalf of public authorities to finance privately operated facilities. These
bonds are used to finance business, 

                                       2
<PAGE>

manufacturing, housing, athletic, and pollution control projects as well as
public facilities, such as mass transit systems, air and sea port facilities,
and parking garages. Payment of interest and repayment of principal on an IDB
depends solely on the ability of the facility's user to meet its financial
obligations and on the pledge, if any, of the real or personal property
financed. The interest earned on IDBs may be subject to the federal alternative
minimum tax.

VARIABLE- AND FLOATING-RATE DEMAND OBLIGATIONS

The Funds may buy variable- and floating-rate demand obligations (VRDOs and
FRDOs). These obligations carry rights that permit holders to demand payment of
the unpaid principal, plus accrued interest, from the issuers or from financial
intermediaries. Floating-rate securities have interest rates that change
whenever there is a change in a designated base rate; variable-rate instruments
provide for a specified, periodic adjustment in the interest rate, which
typically is based on an index. These rate formulas are designed to result in a
market value for the VRDO or FRDO that approximates par value.

OBLIGATIONS WITH TERM PUTS ATTACHED

Each Fund may invest in fixed-rate bonds subject to third party puts and in
participation interests in such bonds held by a bank in trust or otherwise.
These bonds and participation interests have tender options or demand features
that permit the Funds to tender (or put) their bonds to an institution at
periodic intervals and to receive the principal amount thereof.

Benham Management Corporation (BMC), the Funds' investment advisor, expects that
the Funds will pay more for securities with puts attached than for securities
without these liquidity features. BMC may buy securities with puts attached to
keep a Fund fully invested in municipal securities while maintaining sufficient
portfolio liquidity to meet redemption requests or to facilitate management of
the Funds' investments. To ensure that the interest on municipal securities
subject to puts is tax-exempt to the Funds, BMC limits the Funds' use of puts in
accordance with applicable interpretations and rulings of the Internal Revenue
Service (IRS).

Because it is difficult to evaluate the likelihood of exercise or the potential
benefit of a put, puts normally will be determined to have a value of zero,
regardless of whether any direct or indirect consideration is paid. Accordingly,
puts as separate securities are not expected to affect the Funds' weighted
average maturities. Where a Fund has paid for a put, the cost will be reflected
as unrealized depreciation on the underlying security for the period the put is
held. Any gain on the sale of the underlying security will be reduced by the
cost of the put.

There is a risk that the seller of a put will not be able to repurchase the
underlying obligation when, or if, a Fund attempts to exercise the put. To
minimize such risks, the Funds will purchase obligations with puts attached only
from sellers deemed creditworthy by BMC.

TENDER OPTION BONDS

Tender option bonds (TOBs) were created to increase the supply of high-quality,
short-term tax-exempt obligations, and thus they are of particular interest to
the Money Market Fund. However, either Fund may purchase these instruments.

TOBs are created by municipal bond dealers who purchase long-term tax-exempt
bonds in the secondary market, place the certificates in trusts, and sell
interests in the trusts with puts or other 

                                       3
<PAGE>

liquidity guarantees attached. The credit quality of the resulting synthetic
short-term instrument is based on the guarantor's short-term rating and the
underlying bond's long-term rating.

There is some risk that a remarketing agent will renege on a tender option
agreement if the underlying bond is downgraded or defaults. Because of this, BMC
monitors the credit quality of bonds underlying the Funds' TOB holdings and
intends to sell or put back any TOB if the rating on its underlying bond falls
below the second-highest rating category designated by a rating agency.

BMC also takes steps to minimize the risk that the Fund may realize taxable
income as a result of holding TOBs. These steps may include consideration of (i)
legal opinions relating to the tax-exempt status of the underlying municipal
bonds, (ii) legal opinions relating to the tax ownership of the underlying
bonds, and (iii) other elements of the structure that could result in taxable
income or other adverse tax consequences.

After purchase, BMC monitors factors related to the tax-exempt status of the
Fund's TOB holdings in order to minimize the risk of generating taxable income.

WHEN-ISSUED AND FORWARD-COMMITMENTS

The Funds may engage in securities transactions on a when-issued or
forward-commitment basis in which the transaction price and yield are each fixed
at the time the commitment is made, but payment and delivery occur at a future
date (typically 15 to 45 days later).

When purchasing securities on a when-issued or forward-commitment basis, each
Fund assumes the rights and risks of ownership, including the risk of price and
yield fluctuations. While the Funds will make commitments to purchase or sell
securities with the intention of actually receiving or delivering them, it may
nevertheless sell the securities before the settlement date if deemed advisable
as a matter of investment strategy.

In purchasing securities on a when-issued or forward-commitment basis, each Fund
will establish and maintain until the settlement date a segregated account
consisting of cash, U.S. government securities, or other high-quality liquid
debt securities in an amount sufficient to meet the purchase price. When the
time comes to pay for when-issued securities, the Fund will meet its obligations
with available cash, through the sale of securities, or, although it would not
normally expect to do so, through sales of when-issued securities themselves
(which may have a market value greater or less than the Fund's payment
obligation). Selling securities to meet when-issued or forward-commitment
obligations may generate taxable capital gains or losses.

The Funds may sell a security and at the same time make a commitment to purchase
the same security at a future date and specified price. Conversely, the Funds
may purchase a security and at the same time make a commitment to sell the same
security at a future date and specified price. These types of transactions are
executed simultaneously in what are known as "dollar-roll" or "cash-and-carry"
transactions. For example, a broker-dealer may seek to purchase a particular
security that the Funds own. The Funds will sell that security to the
broker-dealer and simultaneously enter into a forward-commitment agreement to
buy it back at a future date. This type of transaction generates income for the
Funds if the dealer is willing to execute the transaction at a favorable price
in order to acquire a specific security.

                                       4
<PAGE>

As an operating policy, each Fund will not commit greater than 50% of its total
assets to when-issued or forward-commitment agreements. If fluctuations in the
value of securities held cause more than 50% of a Fund's total assets to be
committed under when-issued or forward-commitment agreements, BMC need not sell
such agreements, but it will be restricted from entering into further agreements
on behalf of the Fund until the percentage of assets committed to such
agreements is below 50% of total assets.

MUNICIPAL LEASE OBLIGATIONS

Each Fund may invest in municipal lease obligations. These obligations, which
may take the form of a lease, an installment purchase, or a conditional sale
contract, are issued by state and local governments and authorities to acquire
land and a wide variety of equipment and facilities. Generally, the Funds will
not hold such obligations directly as a lessor of the property but will purchase
a participation interest in a municipal lease obligation from a bank or other
third party.

Municipal leases frequently carry risks distinct from those associated with
general obligation or revenue bonds. State constitutions and statutes set forth
requirements that states and municipalities must meet to incur debt. These may
include voter referenda, interest rate limits, or public sale requirements.
Leases, installment purchases, and conditional sale contracts (which normally
provide for the title to the leased asset to pass to the government issuer) have
evolved as a way for government issuers to acquire property and equipment
without meeting their constitutional and statutory requirements for the issuance
of debt.

Many leases and contracts include nonappropriation clauses providing that the
governmental issuer has no obligation to make future payments under the lease or
contract unless money is appropriated for such purposes by the appropriate
legislative body on a yearly or other periodic basis. Municipal lease
obligations also may be subject to abatement risk. For example, construction
delays or destruction of a facility as a result of an uninsurable disaster that
prevents occupancy could result in all or a portion of a lease payment not being
made.

INVERSE FLOATERS (INTERMEDIATE-TERM FUND)

The Intermediate-Term Fund may buy or sell inverse floaters. An inverse floater
is a type of derivative that bears an interest rate that moves inversely to
market interest rates. As market interest rates rise, the interest rate on
inverse floaters goes down, and vice versa. Generally, this is accomplished by
expressing the interest rate on the inverse floater as an above-market fixed
rate of interest, reduced by an amount determined by reference to a market-based
or bond-specific floating interest rate (as well as by any fees associated with
administering the inverse floater program).

Inverse floaters may be issued in conjunction with an equal amount of Dutch
Auction floating-rate bonds (floaters), or a market-based index may be used to
set the interest rate on these securities. Floaters and inverse floaters may be
brought to market by a broker-dealer who purchases fixed-rate bonds and places
them in a trust or by an issuer seeking to reduce interest expenses by using a
floater/inverse floater structure in lieu of fixed-rate bonds.

In the case of a broker-dealer structured offering (where underlying fixed-rate
bonds have been placed in a trust), distributions from the underlying bonds are
allocated to floater and inverse floater holders in the following manner:


                                       5
<PAGE>

(i)  Floater holders receive interest based on rates set at a Dutch Auction,
     which is typically held every 28 to 35 days. Current and prospective
     floater holders bid the minimum interest rate that they are willing to
     accept on the floaters, and the interest rate is set just high enough to
     ensure that all of the floaters are sold.

(ii) Inverse floater holders receive all of the interest that remains on the
     underlying bonds after floater interest and auction fees are paid.

Procedures for determining the interest payment on floaters and inverse floaters
brought to market directly by the issuer are comparable, although the interest
paid on the inverse floaters is based on a presumed coupon rate that would have
been required to bring fixed-rate bonds to market at the time the floaters and
inverse floaters were issued.

Where inverse floaters are issued in conjunction with floaters, inverse floater
holders may be given the right to acquire the underlying security (or to create
a fixed-rate bond) by calling an equal amount of corresponding floaters. The
underlying security may then be held or sold. However, typically, there are time
constraints and other limitations associated with any right to combine interests
and claim the underlying security.

Floater holders subject to a Dutch Auction procedure generally do not have the
right to "put back" their interests to the issuer or to a third party. If a
Dutch Auction fails, the floater holder may be required to hold its position
until the underlying bond matures, during which time interest on the floater is
capped at a predetermined rate.

The secondary market for floaters and inverse floaters may be limited. The
market value of inverse floaters tends to be significantly more volatile than
fixed-rate bonds. The interest rates on inverse floaters may be significantly
reduced, even to zero, if interest rates rise.

SHORT-TERM SECURITIES (INTERMEDIATE-TERM FUND)

Under certain circumstances, the Intermediate-Term Fund may invest in short-term
municipal or U.S. government securities, including money market instruments
(short-term securities). Except as otherwise required for temporary defensive
purposes, BMC does not expect the Funds' investments in short-term securities to
exceed 35% of total assets. If the Fund invests in U.S. government securities, a
portion of dividends paid to shareholders will be taxable at the federal level
and may be taxable at the state level, as ordinary income. BMC intends to
minimize such investments, however, and may allow the Fund to hold cash to avoid
generating taxable dividends when suitable short-term municipal securities are
unavailable.

Pursuant to an exemptive order that BMC received from the Securities and
Exchange Commission (SEC), for liquidity purposes, the Intermediate-Term Fund
may invest up to 5% of its total assets in shares of a money market fund advised
by BMC, provided that the investment is consistent with the Fund's investment
policies and restrictions.

CONCENTRATION OF ASSETS IN OBLIGATIONS ISSUED TO FINANCE SIMILAR PROJECTS OR 
FACILITIES

From time to time, a significant portion of a Fund's assets may be invested in
municipal obligations related to the extent that economic, business, or
political developments affecting one of these obligations could affect the other
obligations in a similar manner. For example, if a Fund invested a 

                                       6
<PAGE>

significant portion of its assets in utility bonds and a state or federal
government agency or legislative body promulgated or enacted new environmental
protection requirements for utility providers, projects financed by utility
bonds could suffer as a class. Additional financing might be required to comply
with the new environmental requirements, and outstanding debt might be
downgraded in the interim. Among other factors that could negatively affect
bonds issued to finance similar types of projects are state and federal
legislation regarding financing for municipal projects, pending court decisions
relating to the validity or means of financing municipal projects, material or
manpower shortages, and declining demand for the projects or facilities financed
by the municipal bonds.

FUTURES AND OPTIONS (INTERMEDIATE-TERM FUND)

The Intermediate-Term Fund may enter into futures contracts, options, or options
on futures contracts. Some futures and options strategies, such as selling
futures, buying puts, and writing calls, hedge the Fund's investments against
price fluctuations. Other strategies, such as buying futures, writing puts, and
buying calls, tend to increase market exposure.
The Fund does not use futures and options transactions for speculative purposes.

Although other techniques may be used to control the Fund's exposure to market
fluctuations, the use of futures contracts may be a more effective means of
hedging this exposure. While a Fund pays brokerage commissions in connection
with opening and closing out futures positions, these costs are lower than the
transaction costs incurred in the purchase and sale of the underlying
securities.

FUTURES CONTRACTS provide for the sale by one party and purchase by another
party of a specific security at a specified future time and price. Futures
contracts are traded on national futures exchanges. Futures exchanges and
trading are regulated under the Commodity Exchange Act by the Commodity Futures
Trading Commission (CFTC), a U.S. government agency. The Fund may engage in
futures and options transactions based on securities indexes, such as the Bond
Buyer Index of Municipal Bonds, that are consistent with the Funds' investment
objectives. The Fund may also engage in futures and options transactions based
on specific securities, such as U.S. Treasury bonds or notes.

Bond Buyer Municipal Bond Index futures contracts differ from traditional
futures contracts in that when delivery takes place, no bonds change hands.
Instead, these contracts settle in cash at the spot market value of the
Municipal Bond Index. Although other types of futures contracts, by their terms,
call for actual delivery or acceptance of the underlying securities, in most
cases the contracts are closed out before the settlement date. A futures
position may be closed by taking an opposite position in an identical contract
(i.e., buying a contract that has previously been sold or selling a contract
that has previously been bought).

To initiate and maintain open positions in a futures contract, a Fund would be
required to make a good faith margin deposit in cash or government securities
with a futures broker or custodian. A margin deposit is intended to assure
completion of the contract (delivery or acceptance of the underlying security)
if it is not terminated prior to the specified delivery date. Minimum initial
margin requirements are established by the futures exchanges and may be revised.
In addition, brokers may establish deposit requirements that are higher than the
exchange minimums.

Once a futures contract position is opened, the value of the contract is marked
to market daily. If the futures contract price changes to the extent that the
margin on deposit does not satisfy margin requirements, the contract holder is
required to pay additional "variation" margin. Conversely, changes in the
contract value may reduce the required margin, resulting in a repayment of
excess 

                                       7
<PAGE>

margin to the contract holder. Variation margin payments are made to or from the
futures broker for as long as the contract remains open and do not constitute
margin transactions for purposes of the Funds' investment restrictions.

RISKS RELATED TO FUTURES AND OPTIONS TRANSACTIONS. Futures and options prices
can be volatile, and trading in these markets involves certain risks. If BMC
applies a hedge at an inappropriate time or judges interest rate trends
incorrectly, futures and options strategies may lower a Fund's return. A Fund
could suffer losses if it were unable to close out its position because of an
illiquid secondary market.

Futures contracts may be closed out only on an exchange that provides a
secondary market for these contracts, and there is no assurance that a liquid
secondary market will exist for any particular futures contract at any
particular time. Consequently, it may not be possible to close a futures
position when BMC considers it appropriate or desirable to do so. In the event
of adverse price movements, the Fund would be required to continue making daily
cash payments to maintain its required margin. If the Fund had insufficient
cash, it might have to sell portfolio securities to meet daily margin
requirements at a time when BMC would not otherwise elect to do so. In addition,
the Fund may be required to deliver or take delivery of instruments underlying
futures contracts it holds. BMC will seek to minimize these risks by limiting
the contracts it enters into on behalf of the Fund to those traded on national
futures exchanges and for which there appears to be a liquid secondary market.

The Fund could suffer losses if the prices of its futures and options positions
were poorly correlated with its other investments or if securities underlying
futures contracts purchased by the Fund had different maturities than those of
the portfolio securities being hedged. Such imperfect correlation may give rise
to circumstances in which the Fund loses money on a futures contract at the same
time that it experiences a decline in the value of its hedged portfolio
securities. The Fund could also lose margin payments it has deposited with a
margin broker if, for example, the broker becomes bankrupt.

Most futures exchanges limit the amount of fluctuation permitted in futures
contract prices during a single trading day. The daily limit establishes the
maximum amount that the price of a futures contract may vary either up or down
from the previous day's settlement price at the end of the trading session. Once
the daily limit has been reached in a particular type of contract, no trades may
be made on that day at a price beyond the limit. However, the daily limit
governs only price movement during a particular trading day and, therefore, does
not limit potential losses. In addition, the daily limit may prevent liquidation
of unfavorable positions. Futures contract prices have occasionally moved to the
daily limit for several consecutive trading days with little or no trading,
thereby preventing prompt liquidation of futures positions and subjecting some
futures traders to substantial losses.

OPTIONS ON FUTURES. By purchasing an option on a futures contract, the Fund
obtains the right, but not the obligation, to sell the futures contract (a put
option) or to buy the contract (a call option) at a fixed "strike" price. The
Fund can terminate its position in a put option by allowing it to expire or by
exercising the option. If the option is exercised, the Fund completes the sale
of the underlying security at the strike price. Purchasing an option on a
futures contract does not require the Fund to make margin payments unless the
option is exercised.

Although it does not currently intend to do so, the Fund may write (or sell)
call options that obligate them to sell (or deliver) the option's underlying
instrument upon exercise of the option. While the receipt of option premiums
would mitigate the effects of price declines, the Fund would give up 

                                       8
<PAGE>

some ability to participate in a price increase on the underlying security. If
the Fund were to engage in options transactions, it would own the futures
contract at the time a call were written and would keep the contract open until
the obligation to deliver it pursuant to the call expired.

RESTRICTIONS ON THE USE OF FUTURES CONTRACTS AND OPTIONS. The Intermediate-Term
Fund may enter into futures contracts, options, or options on futures contracts,
provided that such obligations represent no more than 20% of the Fund's net
assets. Under the Commodity Exchange Act, a fund may enter into futures and
options transactions (i) for hedging purposes without regard to the percentage
of assets committed to initial margin and option premiums or (ii) for other than
hedging purposes, provided that assets committed to initial margin and option
premiums do not exceed 5% of the fund's net assets. To the extent required by
law, the Fund will set aside cash and appropriate liquid assets in a segregated
account to cover its obligations related to futures contracts and options.

The Fund intends to comply with tax rules applicable to regulated investment
companies, including a requirement that gains from the sales of securities and
certain other instruments held less than three months constitute less than 30%
of a Fund's gross income for each fiscal year. Gains on some futures contracts
and options are included in this 30% calculation, which may limit the Fund's
investments in such instruments.

SPECIAL CONSIDERATIONS REGARDING FLORIDA MUNICIPAL SECURITIES

As briefly discussed in the Prospectus, the Funds are susceptible to political,
economic, and regulatory events that affect issuers of Florida municipal
obligations. The following information about risk factors is provided in view of
the Funds' policies of concentrating their assets in Florida municipal
securities. This information is based on independent municipal credit reports
relating to securities offerings of Florida issuers and other publicly available
sources. It does not constitute a complete description of the risk associated
with investing in securities of these issuers. While BMC has not independently
verified this information, it has no reason to believe the information is
inaccurate.

Because the Funds invest primarily in Florida municipal securities, the Funds
will be affected by political and economic conditions and developments within
the state of Florida. In general, the credit quality and credit risk of any
issuer's debt depend on the state and local economy, the health of the issuer's
finances, the amount of the issuer's debt, the quality of management, and the
strength of legal provisions in debt documents that protect debt holders. Credit
risk is usually lower whenever the economy is strong, growing and diversified,
financial operations are sound, and the debt burden is reasonable.

The state of Florida's economy is characterized by a large service sector, a
dependence on the tourism and construction industries, and a large retirement
population. The management of rapid growth has been the major challenge facing
state and local governments. Florida's population has grown rapidly and is now
the fourth largest state; this growth is expected to continue, but at reduced
rates. The retiree component is expected to continue to be a major factor. As
this growth continues, particularly within the retirement population, the demand
for both public and private services will increase, which may strain the service
sector's capacity and impede the state's budget balancing efforts.

In recent years, the Florida economy has been transforming from a narrow base of
agriculture and seasonal tourism into a service and trade economy, with
substantial insurance, banking, and export participation as well as greater
year-round attraction. The outlook for the Florida economy is continued
expansion fueled by population growth but at a slower rate than that of the
1980s.


                                       9
<PAGE>

Debt levels in the state of Florida are moderate to high, reflecting the
tremendous capital demands associated with rapid population growth. Florida is
unusual among states in that all general obligation full faith and credit debt
issues of municipalities must be approved by public referendum and are,
therefore, relatively rare. Most debt instruments issued by local municipalities
and authorities have a narrower pledge of security, such as a sales tax stream,
special assessment revenue, user fees, utility taxes, or fuel taxes. Credit
quality of such debt instruments tends to be somewhat lower than that of general
obligation debt. The state of Florida issues general obligation debt for a
variety of purposes; however, the state constitution requires a specific revenue
stream to be pledged to state general obligation bonds as well.

The state of Florida is heavily dependent upon sales tax, which makes the
state's general fund vulnerable to recession and presents difficulties in
expanding the tax base in an economy increasingly geared to services. This
dependence upon sales tax, combined with economic recession, has resulted in
budgetary shortfalls in the past; Florida has reacted to preserve an adequate
financial position primarily through expenditure reductions. State officials,
however, still face tremendous capital and operating pressures due to the growth
that will continue to strain the state's narrow revenue base. Future budgets may
require a wider revenue base to meet such demands; the most likely candidate for
such revenue enhancement is a tax on consumer services. The creation of a
Florida personal income tax is a remote possibility because it would require an
amendment to the state's constitution. However, there can be no assurance that a
personal income tax will not be implemented in the future if such a tax were to
be imposed, there is no assurance that interest earned on Florida municipal
obligations would be exempt from this tax.

INVESTMENT RESTRICTIONS

Each of the Fund's investment restrictions are set forth below. Except for those
designated as operating policies, these restrictions are fundamental and may not
be changed without approval of "a majority of the outstanding voting securities"
of the Fund as defined in the Investment Company Act of 1940.

A FUND MAY NOT

(1)  Borrow money, except from a bank as a temporary measure to satisfy
     redemption requests or for extraordinary or emergency purposes and provided
     that the Fund maintains asset coverage of at least 300% for all such
     borrowings. A Fund may borrow money for temporary or emergency purposes
     from other funds or portfolios for which BMC is the investment advisor or
     from a joint account of such funds or portfolios as permitted by federal
     regulatory agencies. Before such borrowing from another fund would be
     permissible, the Fund would need to obtain exemptive relief from the staff
     of the SEC. The Fund has no current intent of obtaining such relief.

(2)  Act as an underwriter of securities issued by others, except to the extent
     that the Fund may be considered an underwriter within the meaning of the
     Securities Act of 1933 in the disposition of restricted securities, and
     except to the extent that the purchase of municipal securities or other
     permitted investments directly from the issuer thereof or from an
     underwriter for an issuer and the later disposition of such securities in
     accordance with the Fund's investment policies and techniques may be deemed
     to be an underwriting.

(3)  Purchase or sell real estate, unless acquired as a result of ownership of
     securities or other instruments (but this shall not prevent a Fund from
     investing in securities or other instruments backed by real estate or
     securities of issuers engaged in the real estate business); physical


                                       10
<PAGE>

     commodities or contracts relating to physical commodities; or interests in
     oil, gas and/or mineral exploration or development programs or leases. This
     restriction shall not be deemed to prohibit a Fund from purchasing or
     selling currencies; entering into futures contracts on securities,
     currencies, or on indexes of such securities or currencies, or any other
     financial instruments; and purchasing and selling options on such futures
     contracts.

(4)  Make loans to others, except in accordance with the Fund's investment 
     objective and policies.

(5)  Issue senior securities, except as permitted under the Investment Company
     Act of 1940.

The Funds are also subject to the following restrictions, which are not
fundamental and may therefore be changed by the board of trustees without
shareholder approval.

A FUND MAY NOT

(a)  Purchase equity securities in any companies, including warrants or bonds
     with warrants attached, or any preferred stocks, convertible bonds, or
     convertible debentures.

(b)  Sell securities short, unless it owns or has the right to obtain securities
     equivalent in kind and amount to the securities sold short, and provided
     that transactions in options and futures contracts are not deemed to
     constitute short sales of securities.

(c)  Purchase securities on margin, except that the Fund may obtain such
     short-term credits as are necessary for the clearance of transactions, and
     provided that margin payments in connection with futures contracts and
     options on futures contracts shall not constitute the purchase of
     securities on margin.

(d)  Invest in securities that are not readily marketable or the disposition of
     which is restricted under federal securities laws (collectively, illiquid
     securities) if, as a result, more than 10% of the Florida Municipal Money
     Market Fund's net assets or more than 15% of the Intermediate-Term Fund's
     net assets would be invested in illiquid securities.

(e)  Acquire or retain the securities of any other investment company if, as a
     result, more than 3% of such investment company's outstanding shares would
     be held by the Fund, more than 5% of the value of the Fund's assets would
     be invested in shares of such investment company, or more than 10% of the
     value of the Fund's assets would be invested in shares of investment
     companies in the aggregate, or except in connection with a merger,
     consolidation, acquisition, or reorganization.

(f)  Invest in securities of an issuer that, together with any predecessor or
     unconditional guarantor, has been in operation for less than three years
     if, as a result, more than 5% of the total assets of the Fund would then be
     invested in such securities, except obligations issued or guaranteed by the
     U.S. government or its agencies and municipal securities.

(g)  Purchase any security if, as a result, 25% or more of the value of the
     Fund's total assets would be invested in the securities of issuers having
     their principal business activities in the same industry. However, this
     limitation does not apply to securities issued or guaranteed by the U.S.
     government or any of its agencies or instrumentalities or to municipal
     securities of any type.

Unless otherwise indicated, with the exception of the percentage limitations on
borrowing, the restrictions apply at the time transactions are entered into.
Accordingly, any later increase or 

                                       11
<PAGE>

decrease beyond the specified limitation resulting from a change in the Fund's
net assets will not be considered in determining whether it has complied with
its investment restrictions.

For purposes of the Funds' investment restrictions, the party identified as the
"issuer" of a municipal security depends on the form and conditions of the
security. When the assets and revenues of a political subdivision are separate
from those of the government that created the subdivision, and the security is
backed only by the assets and revenues of the subdivision, the subdivision is
deemed the sole issuer. Similarly, in the case of an IDB, if the bond is backed
only by the assets and revenues of a nongovernmental user, the nongovernmental
user would be deemed the sole issuer. If, in either case, the creating
government or some other entity were to guarantee the security, the guarantee
would be considered a separate security and would be treated as an issue of the
guaranteeing entity.

PORTFOLIO TRANSACTIONS

Each Fund's assets are invested by BMC in a manner consistent with the Fund's
investment objectives, policies, and restrictions, and with any instructions the
board of trustees may issue from time to time. Within this framework, BMC is
responsible for making all determinations as to the purchase and sale of
portfolio securities and for taking all steps necessary to implement securities
transactions on behalf of the Funds. In placing orders for the purchase and sale
of portfolio securities, BMC will use its best possible price and execution and
will otherwise place orders with broker-dealers subject to and in accordance
with any instructions the board of trustees may issue from time to time. BMC
will select broker-dealers to execute portfolio transactions on behalf of the
Funds solely on the basis of best price and execution.

Under normal conditions, the Intermediate-Term Fund's annual portfolio turnover
rate is not expected to exceed 100%. Because a higher turnover rate increases
transaction costs and may increase taxable capital gains, BMC carefully weighs
the potential benefits of short-term investing against these considerations.

The Intermediate-Term Fund's portfolio turnover rate for the fiscal year ended
May 31, 1995, was 36.63%.

Investment decisions are made for each Fund independently from those made for
other funds advised by BMC. From time to time, however, two or more funds
advised by BMC may hold the same security. When two or more funds are
simultaneously engaged in purchasing or selling a security, the prices and
amounts are allocated in a manner believed by BMC to be equitable to each of the
funds involved. In some instances, simultaneous transactions could have a
detrimental effect on the price or value of a security as far as the
participating funds are concerned. In other instances, however, the ability to
participate in volume transactions will produce better prices and executions for
the funds.

VALUATION OF PORTFOLIO SECURITIES

Each Fund's net asset value per share (NAV) is determined by Benham Financial
Services, Inc. (BFS) at 1:00 p.m. Pacific Time each day the New York Stock
Exchange (NYSE) is open for business. The NYSE has designated the following
holiday closings for 1996: New Year's Day (observed), Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving Day, and Christmas Day (observed).
Although BFS expects the same holiday schedule to be observed in the future, the
NYSE may modify its holiday schedule at any time.


                                       12
<PAGE>

BMC typically completes its trading on behalf of each Fund in various markets
before the NYSE closes for the day. Each Fund's share price is calculated by
adding the value of all portfolio securities and other assets, deducting
liabilities, and dividing the result by the number of shares outstanding.
Expenses and interest on portfolio securities are accrued daily.

MONEY MARKET FUND. Securities held by the Money Market Fund are valued at
amortized cost. This method involves valuing an instrument at its cost and
thereafter assuming a constant amortization to maturity of any discount or
premium paid at the time of purchase. While this method provides certainty in
valuation, it generally disregards the effect of fluctuating interest rates on
an instrument's market value. Consequently, the instrument's amortized cost
value may be higher or lower than its market value, and this discrepancy may be
reflected in the Fund's yield. During periods of declining interest rates, for
example, the daily yield on Fund shares computed as described above may be
higher than that of a fund with identical investments priced at market value.
The converse would apply in a period of rising interest rates.

The amortized cost method of valuation is permitted in accordance with Rule 2a-7
under the Investment Company Act of 1940. Under the Rule, a fund holding itself
out as a money market fund must adhere to certain quality and maturity criteria.
In particular, such a fund must limit its investments to U.S. dollar-denominated
instruments determined by its directors or trustees to present minimal credit
risks and that are (i) high-grade obligations rated in accordance with
applicable rules in one of the two highest rating categories for short-term
obligations by at least two rating agencies (or by one if only one has rated the
obligation) or (ii) unrated obligations judged by the advisor, under the
direction of the fund's directors or trustees, to be of comparable quality.
Further, pursuant to Rule 2a-7, a money market fund must maintain a
dollar-weighted average portfolio maturity of 90 days or less and purchase
instruments with remaining maturities of 397 days or less.

The trustees have established procedures designed to stabilize, to the extent
reasonably possible, the Florida Municipal Money Market Fund's NAV at $1.00 per
share. These procedures require the Trust's chief financial officer to notify
the trustees immediately if, at any time, a Fund's weighted average maturity
exceeds 90 days or its NAV, as determined by using available market quotations,
deviates from its amortized cost per share by .25% or more. If such deviation
exceeds .40%, a meeting of the board of trustees' audit committee will be called
to consider what actions, if any, should be taken. If such deviation exceeds
 .50%, the Trust's chief financial officer is instructed to adjust daily dividend
distributions immediately to the extent necessary to reduce the deviation to
 .50% or lower and to call a meeting of the board of trustees to consider further
action.

The board of trustees monitors the levels of illiquid securities, however if the
levels are exceeded, they will take action to rectify these levels.

Actions the board may consider under these circumstances include: (i) selling
portfolio securities prior to maturity, (ii) withholding dividends or
distributions from capital, (iii) authorizing a one-time dividend adjustment,
(iv) discounting share purchases and initiating redemptions in kind, or (v)
valuing portfolio securities at market for purposes of calculating NAV.

INTERMEDIATE-TERM FUND. Securities held by the Intermediate-Term Fund are
normally priced by an independent pricing service, provided that such prices are
believed by BMC to reflect the fair market value of portfolio securities.

Because there are hundreds of thousands of municipal issues outstanding, and the
majority of them do not trade daily, the prices provided by pricing services are
generally determined without regard to 

                                       13
<PAGE>

bid or last sale prices. In valuing securities, the pricing services generally
take into account institutional trading activity, trading in similar groups of
securities, and any developments related to specific securities. The methods
used by the pricing service and the valuations so established are reviewed by
BMC under the general supervision of the board of trustees. There are a number
of pricing services available, and BMC, on the basis of ongoing evaluation of
these services, may use other pricing services or discontinue the use of any
pricing service in whole or in part.

Securities not priced by a pricing service are valued at the mean between the
most recently quoted bid and ask prices provided by broker-dealers. The
municipal bond market is typically a "dealer market"; that is, dealers buy and
sell bonds for their own accounts rather than for customers. As a result, the
spread, or difference between bid and asked prices, for certain municipal bonds
may differ substantially among dealers.

Securities maturing within 60 days of the valuation date may be valued at cost,
plus or minus any amortized discount or premium, unless the trustees determine
that this would not result in fair valuation of a given security. Other assets
and securities for which quotations are not readily available are valued in good
faith at their fair value using methods approved by the board of trustees.

PERFORMANCE

The Funds may quote performance in various ways. Historical performance
information will be used in advertising and sales literature and is not
indicative of future results. The Funds share price, yield, and return will vary
with changing market conditions.

For the MONEY MARKET FUND, yield quotations are based on the change in the value
of a hypothetical investment (excluding realized gains and losses from the sale
of securities and unrealized appreciation and depreciation of securities) over a
seven-day period (base period) and stated as a percentage of the investment at
the start of the base period (base-period return). The base-period return is
then annualized by multiplying by 365/7 with the resulting yield figure carried
to at least the nearest hundredth of one percent.

Calculations of effective yield begin with the same base-period return used to
calculate yield, but the return is then annualized to reflect weekly compounding
according to the following formula:
                                                         365/7
              Effective Yield = [(Base-Period Return + 1)     ] - 1

For the seven-day period ended May 31, 1995, the Money Market Fund's yield was
4.25%, and its effective yield was 4.34%.

For the INTERMEDIATE-TERM FUND, yield quotations are based on the investment
income per share earned during a particular 30-day period, less expenses accrued
during the period (net investment income), and are computed by dividing the
Fund's net investment income by its share price on the last day of the period
according to the following formula:
                                                6
                          YIELD = 2 [(a - b + 1)  - 1]
                                      -----
                                       cd

where a = dividends and interest earned during the period, b = expenses accrued
for the period (net of reimbursements), c = the average daily number of shares
outstanding during the period that were entitled to receive dividends, and d =
the maximum offering price per share on the last day of the period. 

                                       14
<PAGE>

For the 30-day period ended May 31, 1995, the Intermediate-Term Fund's yield was
4.96%.

Total returns quoted in advertising and sales literature reflect all aspects of
a Fund's return, including the effect of reinvesting dividends and capital gain
distributions and any change in the Fund's NAV during the period.

Average annual total returns are calculated by determining the growth or decline
in value of a hypothetical historical investment in a fund over a stated period,
and then calculating the annually compounded percentage rate that would have
produced the same result if the rate of growth or decline in value had been
constant throughout the period. For example, a cumulative total return of 100%
over ten years would produce an average annual total return of 7.18%, which is
the steady annual rate that would equal 100% growth on a compounded basis in ten
years. While average annual total returns are a convenient means of comparing
investment alternatives, investors should realize that the Funds' performance is
not constant over time but changes from year to year and that average annual
total returns represent averaged figures as opposed to actual year-to-year
performance.

Performance for the fiscal year ended May 31, 1995 is listed in the chart below:

                            MONEY MARKET FUND            INTERMEDIATE-TERM FUND

One Year                          3.71%                           7.31%
Since Inception                   3.62                            8.07 

In addition to average annual total returns, each Fund may quote unaveraged or
cumulative total returns reflecting the simple change in value of an investment
over a stated period. Average annual and cumulative total returns may be quoted
as percentages or as a dollar amount and may be calculated for a single
investment, a series of investments, or a series of redemptions over any time
period. Performance information may be quoted numerically or in a table, graph,
or similar illustration.

The Funds' performance may be compared with the performance of other mutual
funds tracked by mutual fund rating services or with other indexes of market
performance. This may include comparisons with funds that, unlike Benham funds,
are sold with a sales charge or deferred sales charge. Sources of economic data
that may be used for making such comparisons may include, but are not limited
to, U.S. Treasury bill, note, and bond yields, money market fund yields, U.S.
government debt and percentage held by foreigners, the U.S. money supply, net
free reserves, and yields on current-coupon GNMAs (source: Board of Governors of
the Federal Reserve System); the federal funds and discount rates (source:
Federal Reserve Bank of New York); yield curves for U.S. Treasury securities and
AA/AAA-rated corporate securities (source: Bloomberg Financial Markets); yield
curves for AAA-rated tax-free municipal securities (source: Telerate); yield
curves for foreign government securities (sources: Bloomberg Financial Markets
and Data Resources, Inc.); total returns on foreign bonds (source: J.P. Morgan
Securities Inc.); various U.S. and foreign government reports; the junk bond
market (source: Data Resources, Inc.); the CRB Futures Index (source: Commodity
Index Report); the price of gold (sources: London a.m./p.m. fixing and New York
Comex Spot Price); rankings of any mutual fund or mutual fund category tracked
by Lipper Analytical Services, Inc. or Morningstar, Inc.; mutual fund rankings
published in major nationally distributed periodicals; data provided by the
Investment Company Institute; Ibbotson Associates, Stocks, Bonds, Bills, and
Inflation; major indexes of stock market performance; and indexes and historical
data supplied by major securities brokerage or investment advisory firms. The
Fund may also utilize reprints from newspapers and magazines furnished by third
parties to illustrate historical performance.


                                       15
<PAGE>

The Funds' shares are sold without a sales charge (or "load"). No-load funds
offer an advantage to investors when compared to load funds with comparable
investment objectives and strategies. For example, if you invest $10,000 in a
no-load fund, 100% of your investment is used to buy shares. If you invest
$10,000 in a fund with a 5.5% load, only $9,450 ($10,000 minus $550) is used to
buy shares. Over time, this difference can have a significant effect on total
return. Assuming a compounded annual growth rate of 10% for both investments,
the no-load fund investment would be worth $25,937 after 10 years, whereas the
load fund investment would be worth only $24,511.

The Benham Group has distinguished itself as an innovative provider of low-cost
true no-load mutual funds. Among other innovations, The Benham Group established
the first no-load fund that invests primarily in zero-coupon U.S. Treasury
securities, the first no-load double tax-free California money market and
short-term bond fund, the first no-load adjustable rate government securities
fund, and the first no-load utilities fund designed to pay monthly dividends.

BMC may obtain fund ratings on the safety of Fund shares from one or more
nationally recognized statistical rating organizations (rating agencies) and may
publish these ratings in advertisements and sales literature.

TAXES

FEDERAL INCOME TAX

Each Fund intends to qualify annually as a "regulated investment company" under
Subchapter M of the Internal Revenue Code of 1986 (the Code), as amended. By so
qualifying, each Fund will not incur federal income and state taxes on its net
investment income and on net realized capital gains to the extent distributed to
shareholders.

It is intended that each Fund's assets will be sufficiently invested in
municipal securities to qualify to pay "exempt-interest dividends" (as defined
in the Code) to shareholders. Each Fund's dividends payable from net tax-exempt
interest earned from municipal securities will qualify as exempt-interest
dividends if, at the close of each quarter of its taxable year, at least 50% of
the value of its total assets consists of municipal securities. Exempt-interest
dividends distributed to shareholders are not included in shareholders' gross
income for purposes of the regular federal income tax. The percentage of income
that is tax-exempt is applied uniformly to all distributions made during each
calendar year. This percentage may differ from the actual percentage of
tax-exempt income received during any particular month.

Each Fund will determine periodically which distributions will be designated as
exempt-interest dividends. If a Fund earns income that is not eligible to be so
designated, the Fund, nonetheless, intends to distribute such income. Such
distributions will be subject to federal, state, and local taxes, as applicable,
in the hands of shareholders.

Distributions of net investment income received by each Fund from investment in
debt securities other than municipal securities, of ordinary income realized
upon the disposition of market discount bonds (including tax-exempt market
discount bonds), and of any net realized short-term capital gains will be
taxable to shareholders as ordinary income. Because the Funds' investment income
is derived from interest rather than dividends, no portion of such distributions
is eligible for the dividends-received deduction available to corporations.


                                       16
<PAGE>

The timing of an investment could have undesirable tax consequences. If a
shareholder opens an account or buys shares for an account before the day a
dividend or distribution is declared, the shareholder may receive a portion of
the investment back as taxable income if that dividend or distribution is not an
exempt-interest dividend.

Under the Code, any distribution designated as being made from a fund's net
realized long-term capital gains is taxable to shareholders as long-term capital
gains, regardless of the length of time shares have been held.

The Funds intend to comply with tax rules applicable to regulated investment
companies, including a requirement that capital gains from the sale of
securities held less than three months constitute less than 30% of a Fund's
gross income for each fiscal year. Gains on some futures contracts and options
are included in this 30% calculation, which may limit the Fund's investments in
such instruments.

Upon the sale or exchange of shares, a shareholder generally will realize a
taxable gain or loss depending upon his or her basis in the shares. Such gain or
loss will be treated as a capital gain or loss if the shares are capital assets
in the shareholder's hands and will be long term if the shareholder's holding
period for the shares is more than one year and, generally, will otherwise be
short term. However, any loss realized upon a sale or redemption of shares
within six months of their purchase will be treated as long-term capital loss to
the extent of capital gain dividends received on such gains.

Any loss realized from a disposition of a Fund's shares held for six months or
less will be disallowed to the extent that dividends received from the Fund have
been designated as exempt-interest dividends. Any loss realized on a sale or
exchange of the Fund's shares also will be disallowed to the extent that the
shares disposed of are replaced (including replacement through reinvesting of
dividends and capital gain distributions in the Fund) within a period of 61
days, beginning 30 days before and ending 30 days after the disposition of the
shares. In such a case, the basis of the shares acquired will be adjusted to
reflect the disallowed loss.

Interest on certain types of industrial development bonds is not exempt from
federal income tax when received by "substantial users" or persons related to
substantial users as defined in the Code. The term "substantial user" includes
any "nonexempt person" who regularly uses in trade or business part of a
facility financed from the proceeds of industrial development bonds. The Funds
may invest periodically in industrial development bonds and, therefore, may not
be appropriate investments for entities that are substantial users of facilities
financed by industrial development bonds or "related persons" of substantial
users. Generally, an individual will not be a related person of a substantial
user under the Code unless he/she or his/her immediate family (spouse, brothers,
sisters, and lineal descendants) owns directly or indirectly in aggregate more
than 50% in the equity value of the substantial user.

Certain options, futures contracts, and forward contracts in which the Funds may
invest are "section 1256 contracts." Gains or losses on section 1256 contracts
generally are considered 60% long-term and 40% short-term capital gains or
losses (60-40). Also, section 1256 contracts held by a Fund at the end of each
taxable year (and, in some cases, for purposes of the 4% excise tax, on October
31 of each year) are marked to market with the result that unrealized gains or
losses are treated as though they were realized.


                                       17
<PAGE>

The hedging transactions undertaken by the Funds may result in straddles for
federal income tax purposes. The straddle rules may affect the character of
gains (or losses) realized by a fund. In addition, losses realized by a fund on
positions that are part of a straddle may be deferred under the straddle rules,
rather than being taken into account in calculating the taxable income for the
taxable year in which such losses are realized. Because only a few regulations
implementing the straddle rules have been promulgated, the tax consequences to
the Funds of hedging transactions are not entirely clear. The hedging
transactions may increase the amount of short-term capital gains realized by the
Funds, which are taxed as ordinary income when distributed to shareholders.

Each Fund may make one or more of the elections available under the Code that
are applicable to straddles. If the Fund makes any of the elections, the amount,
character, and timing of the recognition of gains or losses from the affected
straddle positions will be determined under rules that vary according to the
elections made. The rules applicable under certain of the elections may operate
to accelerate the recognition of gains or losses from the affected straddle
positions.

Because application of the straddle rules may affect the character of gains or
losses, defer losses, and/or accelerate the recognition of gains or losses from
the affected straddle positions, the amount that must be distributed to
shareholders and that will be taxed to shareholders as ordinary income or as a
long-term capital gain may be increased or decreased substantially as compared
to a fund that did not engage in such hedging transactions.

Opinions relating to the tax status of interest derived from individual
municipal securities are rendered by bond counsel to the issuer. The Funds, the
investment manager, and the Fund's counsel do not review the proceedings
relating to the issuance of state or municipal securities on the basis of bond
counsel opinions.

From time to time, proposals have been introduced in Congress for the purpose of
restricting or eliminating the federal income tax exemption for interest on
municipal securities, and similar proposals may be introduced in the future. If
such a proposal were enacted, the availability of municipal securities for
investment by the Funds, and the Funds' NAVs would be adversely affected. Under
these circumstances, the trustees would reevaluate the Funds' investment
objectives and policies and would consider either changes in the structure of
the Trust or its dissolution.

ALTERNATIVE MINIMUM TAX

While the interest on bonds issued to finance essential state and local
government operations is generally tax-exempt, interest on certain nonessential
or private activity securities issued after August 7, 1986, while tax-exempt,
constitutes a tax-preference item for taxpayers in determining alternative
minimum tax liability under the Code and income tax provisions of several
states. The interest on private activity securities could subject a shareholder
to, or increase liability under, the federal alternative minimum tax, depending
on the shareholder's tax situation.

All distributions derived from interest exempt from regular federal income tax
may subject corporate shareholders to, or increase their liability under, the
alternative minimum tax because these distributions are included in the
corporation's adjusted current earnings.

The Trust will inform shareholders annually as to the dollar amount of
distributions derived from interest payments on private activity securities.


                                       18
<PAGE>

STATE AND LOCAL TAXES

Dividends and distributions paid by the Funds to individuals who are Florida
residents will not be subject to personal income taxation by Florida because
Florida does not have a personal income tax. Corporate shareholders that are
subject to the Florida corporate income tax should consult with their tax
advisor regarding the application of the Florida corporate income tax to
dividends and distributions paid by the Funds.

The Funds may apply for rulings from the Florida Department of Revenue (FDR) to
the effect that shares of a Fund will be exempt from the Florida intangibles tax
each year if the Fund's portfolio of investments on January 1 of that year
consists of investments exempt from the Florida intangibles tax. Investments
exempt from the Florida intangibles tax include, but are not limited to, (i)
notes, bonds and other obligations issued by the state of Florida or its
municipalities, counties, and other taxing districts and (ii) notes, bonds, and
other obligations issued by the U.S. government and its agencies. Obligations
issued by the government of Puerto Rico are also exempt if permitted by ruling.
If a Fund's portfolio of investments on January 1 of each year includes
investments that are not exempt from the Florida intangibles tax, the Fund's
shares could be wholly or partially subject to the Florida intangibles tax. The
Funds intend that on January 1 of each year, each Fund's portfolio of
investments will consist solely of investments exempt from the Florida
intangibles tax.

The Funds' dividends may not qualify for exemption under income or other tax
laws of state or local taxing authorities outside of Florida. Shareholders
should consult their tax advisors or state or local tax authorities about the
status of distributions from the Funds in this regard.

The information above is only a summary of some of the tax considerations
affecting the Funds and their shareholders. No attempt has been made to discuss
individual tax consequences. To determine whether the Funds are a suitable
investment based on his or her tax situation, a prospective investor may wish to
consult a tax advisor.

ABOUT THE TRUST

Benham Municipal Trust is a registered open-end management investment company
that was organized as a Massachusetts business trust on May 1, 1984 (the Trust
was formerly known as "Benham National Tax-Free Trust"). Two of the Trust's
eight series are described in this Statement of Additional Information. The
board of trustees may create additional series from time to time.

The Declaration of Trust permits the trustees to issue an unlimited number of
full and fractional shares of beneficial interest without par value, which may
be issued in series (Funds). Shares issued are fully paid and nonassessable and
have no preemptive, conversion, or similar rights.

Each series votes separately on matters affecting that series exclusively.
Voting rights are not cumulative; investors holding more than 50% of the Trust's
(i.e., all series') outstanding shares may elect a board of trustees. The Trust
has instituted dollar-based voting, meaning that the number of votes you are
entitled to is based upon the dollar value of your investment. The election of
trustees is determined by the votes received from all Trust shareholders without
regard to whether a majority of shareholders of any one series voted in favor of
a particular nominee or all nominees as a group. Shares of each series have
equal voting rights, although each series votes separately on matters affecting
that series exclusively.


                                       19
<PAGE>

The shareholders of a Massachusetts business trust could, under certain
circumstances, be held personally liable for its obligations. However, the
Declaration of Trust contains an express disclaimer of shareholder liability for
acts or obligations of the Trust. The Declaration of Trust also provides for
indemnification and reimbursement of expenses of any shareholder held personally
liable for obligations of the Trust. The Declaration of Trust provides that the
Trust will, upon request, assume the defense of any claim made against any
shareholder for any act or obligation of the Trust and satisfy any judgment
thereon. The Declaration of Trust further provides that the Trust may maintain
appropriate insurance (for example, fidelity, bonding, and errors and omissions
insurance) for the protection of the Trust, its shareholders, trustees,
officers, employees, and agents to cover possible tort and other liabilities.
Thus, the risk of a shareholder incurring financial loss on account of
shareholder liability is limited to circumstances in which both inadequate
insurance exists and the Trust itself is unable to meet its obligations.

CUSTODIAN BANK: State Street Bank and Trust Company, 225 Franklin Street,
Boston, Massachusetts 02101, is custodian of the Trust's assets. Services
provided by the custodian bank include (i) settling portfolio purchases and
sales, (ii) reporting failed trades, (iii) identifying and collecting portfolio
income, and (iv) providing safekeeping of securities. The custodian takes no
part in determining the Fund's investment policies or in determining which
securities are sold or purchased by the Fund.

INDEPENDENT AUDITORS: KPMG Peat Marwick LLP, 3 Embarcadero Center, San
Francisco, CA 94111, serves as the Trust's independent auditors. KPMG audits the
annual report and provides tax and other services.

</TABLE>

As of August 31, 1995, the Trust's officers and trustees, as a group, owned less
than 1% of the each Fund's outstanding shares.

INVESTMENT ADVISORY SERVICES

Each Fund has an investment advisory agreement with Benham Management
Corporation (BMC) dated June 1, 1995, that was approved by shareholders on May
31, 1995.

BMC is a California corporation and a wholly owned subsidiary of Twentieth
Century Companies (TCC), a Delaware corporation. BMC, as well as BFS and BDI,
became wholly owned subsidiaries of TCC on June 1, 1995, upon the merger of
Benham Management International (BMI), the former parent of BFS and BDI, into
TCC. BMC has served as investment advisor to the Fund since the Fund's
inception. TCC is a holding company that owns all of the stock of the operating
companies that provide the investment management, transfer agency, shareholder
service, and other services for the Twentieth Century funds. James E. Stowers,
Jr., controls TCC by virtue of his ownership of a majority of its common stock.
BMC has been a registered investment advisor since 1971 and is investment
advisor to other funds in The Benham Group.

Each Fund's agreement with BMC continues for an initial period of two years and
thereafter from year to year provided that, after the initial two-year period,
it is approved at least annually by vote of a majority of the Fund's outstanding
shares or by vote of a majority of the Fund's directors, including a majority of
those directors who are neither parties to the agreement nor interested persons
of any such party, cast in person at a meeting called for the purpose of voting
on such approval.

Each Fund's agreement is terminable on sixty days' written notice, either by the
Fund or by BMC, to the other party, and terminates automatically in the event of
its assignment.


                                       22
<PAGE>

Pursuant to the investment advisory agreement, BMC provides the Fund with
investment advice and portfolio management services in accordance with the
Fund's investment objectives, policies, and restrictions. BMC determines what
securities will be purchased and sold by the Fund and assists the Fund's
officers in carrying out decisions made by the board of directors.

For these services, each Fund pays BMC a monthly investment advisory fee based
on its pro rata share of the dollar amount derived from applying the Fund's
average daily net assets to the following investment advisory fee rate schedule:

         .50% of the first $100 million 
         .45% of the next $100 million       
         .40% of the next $100 million       
         .35% of the next $100 million       
         .30% of the next $100 million       
         .25% of the next $1 billion         
         .24% of the next $1 billion         
         .23% of the next $1 billion         
         .22% of the next $1 billion         
         .21% of the next $1 billion         
         .20% of the next $1 billion         
         .19% of net assets over $6.5 billion
         
Due to reimbursements, the Funds paid no investment advisory fees to BMC during
the fiscal period from April 11, 1994 (commencement of operations), through May
31, 1995.

ADMINISTRATIVE AND TRANSFER AGENT SERVICES

Benham Financial Services, Inc., a wholly owned subsidiary of TCC, is the
Trust's agent for transfer and administrative services. For administrative
services, each Fund pays BFS a monthly fee based on its pro rata share of the
dollar amount derived from applying the average daily net assets of all of the
funds in The Benham Group to the following administrative fee schedule:

GROUP ASSETS                        ADMINISTRATIVE FEE RATE

up to $4.5 billion                           .11%
up to $6 billion                             .10
up to $9 billion                             .09
over $9 billion                              .08

For transfer agent services, each Fund pays BFS monthly fees of $1.3958 for each
shareholder account maintained and $1.35 for each shareholder transaction
executed during the month.

Due to reimbursements, the Funds paid no administrative services or transfer
agent fees to BFS during the fiscal period from April 11, 1994 (commencement of
operations), through May 31, 1994, and for the year ended May 31, 1995.

DIRECT FUND EXPENSES

Each Fund pays certain operating expenses that are not assumed by BMC or BFS.
These include fees and expenses of the independent trustees; custodian, audit,
and pricing fees; fees of outside counsel and counsel employed directly by the
Trust; costs of printing and mailing prospectuses, statements of 

                                       23
<PAGE>

additional information, proxy statements, notices, confirmations, and reports to
shareholders; fees for registering the Fund's shares under federal and state
securities laws; brokerage fees and commissions; trade association dues; costs
of fidelity and liability insurance policies covering the Fund; costs for
incoming WATS lines maintained to receive and handle shareholder inquiries; and
organizational costs.

EXPENSE LIMITATION AGREEMENTS

BMC may recover amounts absorbed on behalf of the Fund during the preceding 11
months if, and to the extent that, for any given month, the Fund's expenses were
less than the expense limit in effect at that time. BMC has agreed to limit each
Fund's expenses to a specified percentage of average daily net assets for a
limited amount of time as listed below.

FUND                                 EXPENSE LIMIT

Money Market Fund                        .65%
Intermediate-Term Fund                   .69%

The Funds' contractual expense limit is subject to annual renewal. The expense
limit for each Fund for the year ended May 31, 1995 was .66% of average daily
net assets.

Net reimbursements paid by BMC for the year ended May 31, 1995, were $201,445
and $70,638 for the Money Market Fund and Intermediate-Term Fund, respectively.

ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

The Funds' shares are available only to residents of California, Florida,
Georgia, Illinois, Michigan, New Jersey, and Pennsylvania. The Funds' shares are
continuously offered at net asset value. Certificates are issued (without
charge) only when requested in writing. Certificates are not issued for
fractional shares. Dividend and voting rights are not affected by the issuance
of certificates.

The Benham Group may reject or limit the amount of an investment to prevent any
one shareholder or affiliated group from controlling the Trust or one of its
series; to avoid jeopardizing a series' tax status; or whenever, in management's
opinion, such rejection is in the Trust's or a series' best interest. The matrix
below shows the names, addresses, and holdings of all shareholders of record who
owned more than 5% of a Fund's outstanding shares.

The Benham Group charges neither fees nor commissions on the purchase and sale
of Benham fund shares. However, BFS may charge fees for special services
requested by a shareholder or necessitated by acts or omissions of a
shareholder. For example, BFS may charge a fee for processing dishonored
investment checks or stop-payment requests. BFS charges $10 per hour for account
research requested by investors. This charge will be assessed, for example, when
a shareholder request requires more than one hour of research on historical
account records. The fees charged are based on the estimated costs of performing
shareholder-requested services and are not intended to increase income to BFS.

Share purchases and redemptions are governed by California law.

MUNICIPAL SECURITIES RATINGS

Securities rating descriptions provided under this heading are excerpted from
publications of Moody's Investors Service, Inc. and Standard & Poor's
Corporation.

DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S MUNICIPAL BOND RATINGS:

Aaa: Bonds that are rated "Aaa" are judged to be of the highest quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edge." Interest payments are protected by a large or exceptionally stable
margin, and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.

Aa: Bonds that are rated "Aa" are judged to be of high quality by all standards.
Together with the Aaa group, they comprise what are generally known as
high-grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities, or fluctuation of
protective elements may be of greater amplitude, or there may be other elements
present that make long-term risks appear somewhat larger than in Aaa securities.

A: Bonds that are rated "A" possess many favorable investment attributes and are
considered to be upper medium-grade obligations. Factors giving security to
principal and interest are considered adequate, but elements may be present that
suggest a susceptibility to impairment sometime in the future.


                                       25
<PAGE>

Baa: Bonds that are rated "Baa" are considered medium-grade obligations, i.e.,
they are neither highly protected nor poorly secured. Interest payments and
principal security appear adequate for the present, but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and, in
fact, have speculative characteristics as well.

Ba: Bonds that are rated "Ba" are judged to have speculative elements; their
future cannot be considered as well assured. Often the protection of interest
and principal payments may be very moderate and thereby not well safeguarded
during both good and bad times in the future. Uncertainty of position
characterizes bonds in this class.

B: Bonds that are rated "B" generally lack characteristics of a desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be limited.

Caa: Bonds that are rated "Caa" are of poor standing. Such issues may be in
default, or there may be elements of danger present with respect to principal or
interest.

Ca: Bonds that are rated "Ca" represent obligations that are speculative to a
high degree. Such issues are often in default or have other marked shortcomings.

C: Bonds that are rated "C" are the lowest-rated class of bonds, and issues so
rated can be regarded as having extremely poor prospects of ever attaining any
real investment standing.

NOTE: Moody's may apply the numerical modifier "1" for municipally backed bonds
and modifiers "1," "2," and "3" for corporate-backed municipal bonds. The
modifier "1" indicates that the security ranks in the higher end of its generic
rating category; the modifier "2" indicates a mid-range ranking; and the
modifier "3" indicates that the issue ranks in the lower end of its generic
rating category.

DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S RATINGS OF NOTES AND
VARIABLE-RATE DEMAND OBLIGATIONS:

Moody's ratings for state and municipal short-term obligations are designated
Moody's Investment Grade or MIG. Such ratings recognize the differences between
short-term credit and long-term risk. Short-term ratings on issues with demand
features (variable-rate demand obligations) are differentiated by the use of the
VMIG symbol to reflect such characteristics as payment upon periodic demand
rather than on fixed maturity dates and payments relying on external liquidity.

MIG 1/VMIG 1: This designation denotes best quality. There is strong protection
present through established cash flows, superior liquidity support, or
demonstrated broad-based access to the market for refinancing.

MIG 2/VMIG 2: This denotes high quality. Margins of protection are ample,
although not as large as in the preceding group.

DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S TAX-EXEMPT COMMERCIAL PAPER
RATINGS:

Moody's commercial paper ratings are opinions of the ability of issuers to
punctually repay those promissory obligations that have an original maturity not
exceeding nine months. Moody's makes no representation that such obligations are
exempt from registration under the Securities Act of 1933, 

                                       26
<PAGE>

nor does it represent that any specific note is a valid obligation of a rated
issuer or issued in conformity with any applicable law. The following
designations, all judged to be investment grade, indicate the relative repayment
ability of rated issuers of securities in which the Funds may invest.

PRIME - 1: Issuers rated "Prime - 1" (or supporting institutions) have a
superior ability for repayment of senior short-term promissory obligations.

PRIME - 2: Issuers rated "Prime - 2" (or supporting institutions) have a strong
ability for repayment of senior short-term promissory obligations.

DESCRIPTION OF STANDARD & POOR'S CORPORATION'S RATINGS FOR MUNICIPAL BONDS:

INVESTMENT GRADE

AAA: Debt rated "AAA" has the highest rating assigned by Standard & Poor's.
Capacity to pay interest and repay principal is extremely strong.

AA: Debt rated "AA" has a very strong capacity to pay interest and repay
principal and differs from the highest-rated issues only in a small degree.

A: Debt rated "A" has a strong capacity to pay interest and repay principal,
although it is somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than debt in higher-rated categories.

BBB: Debt rated "BBB" is regarded as having an adequate capacity to pay interest
and repay principal. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than in higher-rated categories.

SPECULATIVE

BB, B, CCC, CC: Debt rated in these categories is regarded as having
predominantly speculative characteristics with respect to capacity to pay
interest and repay principal. While such debt will likely have some quality and
protective characteristics, these are outweighed by large uncertainties or major
risk exposures to adverse conditions.

BB: Debt rated "BB" has less near-term vulnerability to default than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse business, financial, or economic conditions that could lead to
inadequate capacity to meet timely interest and principal payments. The "BB"
rating category is also used for debt subordinated to senior debt that is
assigned an actual or implied "BBB-" rating.

B: Debt rated "B" has a greater vulnerability to default but currently has the
capacity to meet interest payments and principal repayments. Adverse business,
financial, or economic conditions will likely impair capacity or willingness to
pay interest and repay principal. The "B" rating category is also used for debt
subordinated to senior debt that is assigned an actual or implied "BB" or "BB-"
rating.

CCC: Debt rated "CCC" has a currently identifiable vulnerability to default and
is dependent upon favorable business, financial, and economic conditions to meet
timely payment of interest and repayment of principal. In the event of adverse
business, financial or economic conditions, it is not 

                                       27
<PAGE>

likely to have the capacity to pay interest and repay principal. The "CCC"
rating category is also used for debt subordinated to senior debt that is
assigned an actual or implied "B" or "B-" rating.

CC: The rating "CC" typically is applied to debt subordinated to senior debt
that is assigned an actual or implied "CCC" debt rating.

C: The "C" rating is typically applied to debt subordinated to senior debt that
is assigned an actual or implied "CCC-" debt rating. The "C" rating may be used
to cover a situation where a bankruptcy petition has been filed, but debt
service payments are continued. 
CI: The "CI" rating is reserved for income bonds on which no interest is being 
paid.

D: Debt rated "D" is in default, and payment of interest and/or repayment of
principal is in arrears.

PLUS (+) OR MINUS (-): The ratings from "AA" to "CCC" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.

DESCRIPTION OF STANDARD & POOR'S CORPORATION'S RATINGS FOR INVESTMENT GRADE
MUNICIPAL NOTES AND SHORT-TERM DEMAND OBLIGATIONS:

SP-1: Issues carrying this designation have a very strong or strong capacity to
pay principal and interest. Those issues determined to possess overwhelming
safety characteristics will be given a plus (+) designation.

SP-2: Issues carrying this designation have a satisfactory capacity to pay
principal and interest.

DESCRIPTION OF STANDARD & POOR'S CORPORATION'S RATINGS FOR DEMAND OBLIGATIONS
AND TAX-EXEMPT COMMERCIAL PAPER:

A Standard & Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days. The two rating categories for securities in which the Funds may invest
are as follows:

A-1: This highest category indicates that the degree of safety regarding timely
payment is strong. Those issues determined to possess extremely strong safety
characteristics are denoted with a plus (+) designation.

A-2: Capacity for timely payment on issues with this designation is
satisfactory. However, the relative degree of safety is not as high as for
issues designated "A-1."
