                         SUPPLEMENT TO PROSPECTUS FOR
                             NORTH AMERICAN FUNDS
                 DATED MARCH 1, 1999, AS REVISED MAY 13, 1999

The investment objective of the International Equity Fund (the "International 
Fund") as stated on page 3 of the Prospectus has been approved by the Board of  
Trustees of North American Funds("Trustees"), but is subject to approval by the 
international Fund's shareholders. A meeting of the International Fund's 
shareholders has been called for June 2, 1999 for the purpose of voting on such 
approval. Until this approval is obtained, the investment objective of the Fund 
is to seek long-term growth of capital and income. In addition to the investment
strategies described on page 25 of the Prospectus, MSAM presently also considers
an additional dividend yield factor when making country and sector weightings. 
This additional factor will be eliminated if shareholders approve the proposed 
investment objective stated on page 3 of the Prospectus, which does not include 
an income component.

                                                                    May 13, 1999

Section I:

Fund Summaries

North American Funds (the "Trust") is a group of mutual funds that includes
fifteen separate investment portfolios, or Funds. Each Fund has a specific,
unique investment objective. Each Fund has a subadvisor, a firm responsible for
making investment decisions for the Fund.

The summaries on the next 15 pages describe each Fund's investment objective and
principal investment strategies, list the main risks of investing in the Fund,
and show the Fund's past investment performance. Explanations of the main risks
of investing in each Fund starts on page 17.

Below most of the Funds' descriptions are a chart and a table (the newer
Tax-Sensitive Equity and Emerging Growth Funds do not have charts and tables
because they were less than one year old as of December 31, 1998).

The bar chart shows how the investment returns of one class of each Fund's
shares have varied in the past ten years, or in the years since the Fund began
if it is less than ten years old. The bar chart does not reflect sales charges;
if it did, performance would be less than shown.

The Table (the Average Annual Total Return Table) following each bar chart shows
how that Fund's average annual returns for each Class of shares for the last
one, five and ten years (or since the Fund began, for newer Funds) compared to
returns of a broad-based securities market index. The table reflects sales
charges, including the maximum initial sales charge for Class A shares, and the
maximum applicable Deferred Sales Charge for Class B and Class C shares. Each
Fund's bar chart and Average Annual Total Return Table provides an indication of
the historical risk/return of an investment in the Fund.

It is important to remember that past performance does not predict future
performance, and that as with any investment, it is possible for investors to
lose money on investments in the Funds. An investment in any of the Funds is not
a deposit of a bank and is not insured by the Federal Deposit Insurance
Corporation or any other government agency.

International Equity Fund
Investment Goal and Strategies

The investment objective of the International Equity Fund is to seek long-term
capital appreciation. Morgan Stanley Asset Management ("MSAM"), the Fund's
subadvisor, pursues this objective by investing primarily in accordance with
country and sector weightings determined by MSAM in equity securities of
non-U.S. issuers which, in the aggregate, replicate broad market indices.

MSAM seeks to maintain a diversified portfolio of international equity
securities based on a top-down approach that emphasizes country and sector
selection and weighting rather than individual stock selection. MSAM capitalizes
on the significance of country and sector selection in international equity
portfolio returns by over- and underweighting countries based on three factors:
(i) valuation, (ii) fundamental change, and (iii) short-term market momentum/
technicals.

The Fund may use various instruments that derive their values from those of
specified securities, indices, currencies or other points of reference for both
hedging and non-hedging purposes, Derivatives may include futures, options,
forward contracts, swaps, and structured notes. These derivatives, including
those used to manage risk, are themselves subject to risks of the different
markets in which they trade and, therefore, may not serve their intended
purposes.

Main Investing Risks
o  Currency Risk
o  Derivatives Risk
o  Equity Risk
o  Foreign Investment Risk
o  Liquidity Risk
o  Management Risk

The bar chart and table provide an indication of risk by showing the variability

Global Equity Fund
Investment Goal and Strategies

The investment objective of the Global Equity Fund is long-term capital
appreciation. To achieve this objective, Morgan Stanley Asset Management Inc.
("MSAM"), the Fund's subadvisor, invests in a globally diversified portfolio of
equity securities.

MSAM's investment focus is the selection of individual stocks, with an eye
toward value. To choose stocks for the Fund, MSAM identifies stocks that it
believes to be undervalued in relation to the issuer's assets, cash flow,
earnings and revenues. To decide whether or not these stocks are suitable for
investment, MSAM estimates the future value of these stocks using a mathematical
model.

Under normal circumstances, at least 65% of the Fund's total assets will be
invested in equity securities and at least 20% of the Fund's total assets will
be invested in the common stocks of U.S. issuers. The Fund may invest up to 80%
of its total assets in foreign securities. Although the Fund expects to invest
primarily in securities listed on stock exchanges, it will also invest in equity
securities that are traded over-the-counter or that are not admitted to listing
on a stock exchange or dealt in on a regulated market. The Fund may invest in
derivatives.

Main Investing Risks
o  Currency Risk
o  Derivatives Risk
o  Equity Risk, particularly the risk associated with investments in value
   stocks
o  Foreign Investment Risk
o  Management Risk

The bar chart and table provide an indication of risk by showing the variability

Emerging Growth Fund
Investment Goal and Strategies

The investment objective of the Emerging Growth Fund is maximum capital
appreciation. Warburg Pincus Asset Management, Inc. ("Warburg"), the Fund's
subadvisor, pursues this objective by investing primarily in equity securities
of U.S. companies. The focus of the Fund is emerging growth companies, which
often are small or medium-size companies that reflect growth characteristics
such as positive earnings comparisons and potential for accelerated growth.

The Fund may also invest in high-quality bonds, and to a certain extent, foreign
securities. The Fund may invest in derivatives.

The Fund is not "diversified," which means that it may invest in a relatively
small number of issuers of securities, and its value may be affected very
significantly by the change in value of a single security.

Main Investing Risks
o  Concentration Risk
o  Credit Risk
o  Currency Risk
o  Derivatives Risk
o  Equity Risk, particularly the risks associated with investing in smaller
   companies

value of outstanding securities) between $500 million and $5 billion.

Tax-Sensitive Equity Fund
Investment Goal and Strategies

The Fund's investment objective is to maximize after-tax total return, with
emphasis on long-term growth of capital, primarily through investment in equity
securities of companies that appear to be undervalued. Standish, Ayer & Wood,
Inc., ("Standish"), the Fund's subadvisor, uses tax-sensitive strategies
designed to reduce the impact of federal income tax on the after-tax returns
actually achieved by the Fund's shareholders. The Fund focuses on medium to
large capitalization companies with above-average capital growth potential.
Standish emphasizes individual stock selection rather than attempting to time
which industries or sectors may perform best. Standish selects stocks for the
Fund's portfolio by:

o  Using a mathematical model to identify companies that have strong and
   consistent historic earnings, are valued attractively by the market, and have
   improving growth prospects.

o  Using fundamental research and qualitative analysis to evaluate the stocks
   identified by the mathematical model. Standish looks for companies with
   sustainable profit growth, proven management teams, attractive businesses,
   and strong financial characteristics. To reduce the impact of federal and
   state income taxes on the Fund's after-tax returns, the Fund:

o  Minimizes sales of securities that result in capital gains. If this cannot be
   avoided, the Fund will sell the securities with the smallest capital gains,
   and will sell securities with long-term gains first.

o  Sells securities to create capital losses, which can offset realized capital
   gains.

o  Favors low yield stocks and limits income-producing investments.

The Fund may invest in derivatives.

Main Investing Risks
o  Derivatives Risk
o  Equity Risk, including particular risks associated value stocks
o  Foreign Investment Risk
o  Management Risk


                                                                               8

Growth and Income Fund
Investment Goal and Strategies

The investment objective of the Growth and Income Fund is to provide long-term
growth of capital and income consistent with prudent investment risk. Wellington
Management Company, LLP ("Wellington Management"), the Fund's subadvisor,

stocks of U.S. issuers which Wellington Management believes are of high quality.
The Fund will typically invest in dividend-paying stocks of larger companies.
The Fund may invest up to 20% of its total assets in foreign securities.

To select stocks for the Fund, Wellington Management assesses a company and its
business environment, management, balance sheet, income statement, anticipated
earnings and dividends, and other related measures of Wellington Management will
also monitor and evaluate the economic and political climate and the principal
securities markets of the country in which each company is located. The Fund may
invest in derivatives.

The value of your investment in a Fund can change for many reasons, and may
decrease. The primary reasons for possible decreases in a Fund's value are
called "Main Investing Risks," and are explained in this section. Because the
types of investments a Fund makes change over time, the types of risks affecting
the Fund will change as well. Section II of the Prospectus includes more
information about other risks that might affect the Funds' values.

Concentration Risk
Investment professionals believe that investment risk can be reduced through
diversification, which is simply the practice of choosing more than one type of
investment. On the other hand, concentrating investments in a smaller number of
securities increases risk.

Credit Risk
Credit risk is the risk that the issuer or the guarantor (the entity that agrees
to pay the debt if the issuer cannot) of a debt or fixed income security, or the
counterparty to a derivatives contract or a securities loan, will not repay the
principal and interest owed to the investors or otherwise honor its obligations.
There are different levels of credit risk. Funds that invest in lower-rated
securities have higher levels of credit risk. Lower-rated or unrated securities
of equivalent quality (generally known as junk bonds) have very high levels of
credit risk. Securities that are highly rated have lower levels of credit risk.

Funds may be subject to greater credit risk because they may invest in debt
securities issued in connection with corporate restructurings by highly
leveraged (indebted) issuers and in debt securities not current in the payment
of interest or principal, or in default.

Funds that invest in foreign securities are also subject to increased credit
risk because of the difficulties of requiring foreign entities, including
issuers of sovereign (national) debt, to honor their contractual commitments,
and because a number of foreign governments and other issuers are already in
default.

Currency Risk
Funds that invest in securities denominated in and/or are receiving revenues in
foreign currencies are subject to currency risk. Currency risk is the risk that
foreign currencies will decline in value relative to the U.S. dollar. In the
case of hedging positions, this is the risk that the U.S. dollar will decline in
value relative to the currency hedged.

Derivatives Risk
Derivatives are financial contracts between two parties whose value depends on,
or is derived from, the change in value of an underlying asset, reference rate
or index. When the value of the underlying security or index changes, the value
of the derivative changes as well. As a result, derivatives can lose all of
their value very quickly. Derivatives also offer the opportunity for great
increases in value. Because derivatives are contracts between parties, there is
also some credit risk associated with using derivatives. Additional risks
associated with derivatives include mispricing and improper valuation.
Derivatives risk for some Funds will be increased by their investments in
structured securities.

Equity Risk
Equity securities, such as a company's common stock, may fall in value in
response to factors relating to the issuer, such as management decisions or
falling demand for a company's goods or services. Factors affecting a company's
particular industry, such as increased production costs, may affect the value of
its equity securities. Equity securities also rise and fall in value as a result
of factors affecting entire financial markets, such as political or economic
developments, or changes in investor psychology.

Growth stocks are the stocks of companies that have earnings that are expected
to grow relatively rapidly. As a result, the values of growth stocks may be more
sensitive to changes in current or expected earnings than the values of other
stocks.

Value stocks are the stocks of companies that are not expected to experience
significant earnings growth, but that are undervalued, or are cheap relative to
the value of the company and its business as a whole. These companies may have
experienced some recent troubles that have caused their stocks to be out of
favor. If the market does not recognize the value of the company over time, the
price of its stock may fall, or simply may not increase as expected.

Market capitalization refers to the total value of a company's outstanding
stock. Smaller companies with market capitalizations of less than $1 billion or
so are more likely than larger companies to have limited product lines, smaller
markets for their products and services, and they may depend on a small or
inexperienced management group. Small company stocks may not trade very
actively, and their prices may fluctuate more than stocks of other companies.
Stocks of smaller companies may be more vulnerable to negative changes than
stocks of larger companies.

Foreign Investment Risk
Funds investing in foreign securities may experience rapid changes in value. One
reason for this volatility is that the securities markets of many foreign
countries are relatively small, with a limited number of companies representing
a small number of industries. Also, foreign securities issuers are usually not
subject to the same degree of regulation as U.S. issuers. Reporting, accounting
and auditing standards of foreign countries differ, in some cases significantly,
from U.S. standards.

The possibility of political instability or diplomatic developments in foreign
countries could trigger nationalization of companies and industries,
expropriation (confiscation of property), extremely high levels of taxation, and
other negative developments. In the event of nationalization, expropriation or
other confiscation, a Fund could lose its entire investment. Funds that invest
in sovereign debt obligations are exposed to the risks of political, social and
economic change in the countries that issued the bonds.

Interest Rate Risk or Market Risk
Interest rate risk or market risk is the risk that a change in interest rates
will negatively affect the value of a security. This risk applies primarily to
debt securities such as bonds, notes and asset backed securities. Debt
securities are obligations of the issuer to make payments of principal and/ or
interest on future dates. As interest rates rise, an investment in a Fund can
lose value, because the value of the securities the Fund holds may fall.

Market risk is generally greater for Funds that invest in debt securities with
longer maturities. This risk may be increased for Funds that invest in
mortgage-backed or other types of asset-backed securities that are often
prepaid. Even Funds that invest in the highest quality debt securities are
subject to interest rate risk.

Liquidity Risk
Liquidity risk is the risk that a Fund will not be able to sell a security
because there are too few people who actively buy and sell, or trade, that
security on a regular basis. A Fund holding an illiquid security may not be able
to sell the security at a fair price. Liquidity risk increases for Funds
investing with derivatives, foreign investments and restricted securities, which
all involve increased liquidity risk.

Management Risk
Management risk is the risk that the management of a Fund, despite using various
investment and risk analysis techniques, may not produce the desired investment
results.

*     For purchases of $1 million or more.
**    5% first and second year; 4% third year; 3% fourth year; 2% fifth year; 1%
      sixth year and 0% thereafter.

****  Reflects terms of the Advisory Agreement which may not be changed without
      a shareholder vote.

The higher Distribution Fees borne by Class B and Class C shares may cause
long-term shareholders to pay more in sales charges than the maximum permitted
front-end sales charge on Class A shares.

By translating "Total Annual Fund Operating Expenses" into dollar amounts, these
examples help you compare the costs of investing in a particular Fund, or a
particular class of shares, with the costs of investing in other mutual funds.

The examples assume that you:
o  Invest $10,000 in a Fund for the time period indicated and then redeem all of
   your shares at the end of those periods.
o  Your investment earns a 5% return each year and that each Fund's operating
   expenses remain the same.

More Information About
Investment Objectives,
Strategies and Risks

This Prospectus does not attempt to disclose all of the different investment
techniques that the Funds might use, or all of the types of securities in which
the Funds might invest. As with any mutual fund, investors must rely on the
professional judgment and skill of the Funds' management. A subadvisor may
choose not to use some or all of the investment techniques available to a Fund,
and these choices may cause the Fund to lose money or not achieve its goal.

Each Fund has a unique investment goal (see the Fund Summaries) that it tries to
achieve through its investment strategies. The investment goals, or objectives,
of the Funds cannot be changed without the approval of the holders of a majority
of the outstanding shares of each Fund. However, except for certain investment
restrictions, the strategies a Fund uses to achieve its investment objective may
be changed by the Trustees without approval of the shareholders. Because each
Fund is different, they have different investment policies and risks, and will
also have different returns over time. This section provides additional
information about the Funds, and should be read in conjunction with the Fund
Summaries.

International Small Cap Fund
The Fund may invest without limit in American Depositary Receipts and American
Depositary Shares (collectively, "ADRs"). ADRs are receipts representing shares
of a foreign corporation held by a U.S. bank that entitle the holder to all
dividends and capital gains on the underlying foreign shares. ADRs are
denominated in U.S. dollars and trade in the U.S. securities markets.

The Fund may invest a significant portion of its assets in the securities of
small companies. Small companies are still in the developing stages of their
life cycles and have limited product lines, markets or financial resources
and/or lack management depth. The securities of small companies may have limited
marketability and may experience more abrupt or erratic movements in price than
securities of larger companies or the market averages in general. Because of
this, the net asset value of the International Small Cap Fund may fluctuate more
widely than popular market averages.

The Fund may also invest in convertible securities, preferred stocks, bonds,
debentures and other corporate obligations when Founders believes that these
investments offer opportunities for capital appreciation.

The Fund may invest in investment-grade bonds, debt securities and corporate
obligations (Baa or higher by Moody's, or BBB or higher by S&P). The Fund may
choose to invest in lower-rated (Ba or lower by Moody's and BB or lower by S&P)
convertible securities and preferred stocks. The Fund may also invest in unrated
convertible securities and preferred stocks if Founders believes they are
equivalent in quality to the rated securities that the Fund may buy.

The Fund will not invest more than 5% of its total assets in unrated or below
investment grade fixed-income securities, with the exception of preferred
stocks. If the Fund holds securities that are downgraded after they are
purchased, the Fund does not have to sell them unless the total Fund assets in
unrated and below investment grade securities reach 5% of assets.

Since the Fund's assets will be invested primarily in foreign securities and
since substantially all of the Fund's revenues will be received in foreign
currencies, the Fund's net asset values will be affected by changes in currency
exchange rates. The Fund will pay dividends in dollars and will incur currency
conversion costs.


                                                                              24

International Equity Fund
MSAM's Active International Allocation team analyzes both the global economic
environment and the economies of the industrialized countries comprising the
MSCI Europe, Australasia, Far East (EAFE) Index. EAFE countries include Japan,
most nations in Western Europe, Australia, New Zealand, Hong Kong and Singapore.
MSAM views each EAFE country and major sectors as unique investment
opportunities and evaluates prospects for value, growth, inflation, interest
rates, corporate earnings, dividend yield, liquidity and risk characteristics,
investor sentiment and currency outlook. After determining to invest in an EAFE
country, MSAM establishes overweight, underweight or neutral positions relative
to the EAFE Index. Within the EAFE countries or sectors selected for investment,
MSAM purchases optimized baskets of equity securities designed to track the
local market index within a specified tolerance. The Fund does not invest in
securities of U.S. issuers. MSAM considers an issuer to be from a particular
EAFE country if (i) its principal securities trading market is in that country;
(ii) alone or on a consolidated basis it derives 50% or more of its annual
revenue from either goods produced, sales made or services performed in that
country; or (iii) it is organized under the laws of, and has a principal office
in, that country.

The Fund will limit its use of derivatives for non-hedging purposes to 33 1/3%
of its total assets measured by the aggregate notional amount of outstanding
derivatives. While the use of derivatives may be advantageous to the Fund, if
MSAM is not successful in employing them, the Fund's performance may be worse
than if it did not make such investments.

Emerging market countries are countries that major international financial
institutions, such as the World Bank, generally consider to be less economically
mature than developed nations, such as the United States or most nations in
Western Europe. Emerging market countries can include every nation in the world
except the United States, Canada, Japan, Australia, New Zealand and most
countries located in Western Europe. Emerging market countries may be more
likely to experience political turmoil or rapid changes in economic conditions
than more developed countries, and the financial condition of issuers in
emerging market countries may be more precarious than in other countries. The
characteristics result in greater risk of price volatility in emerging market
countries, which may be heightened by currency fluctuations relative to the U.S.
dollar.

Global Equity Fund
The Fund invests primarily in common and preferred stocks, convertible
securities, rights and warrants to purchase common stocks, American and Global
Depositary Receipts and other equity securities of issuers throughout the world,
including issuers in the U.S. and emerging market countries.

Under normal circumstances, at least 65% of the value of the total assets of the
Fund will be invested in equity securities and at least 20% of the value of the
Fund's total assets will be invested in the common stocks of U.S. issuers. The
Fund may also invest in money market instruments. Although the Fund intends to
invest primarily in securities listed on stock exchanges, it will also invest in
equity securities that are traded over-the-counter or that are not admitted to
listing on a stock exchange or dealt in on a regulated market. Privately traded
securities may have additional liquidity risks. The Fund may also engage in
forward foreign currency transactions and purchase when-issued or delayed
delivery securities.

MSAM's investment focus is the selection of individual stocks, with an eye
toward value. To choose stocks for the Fund, MSAM identifies stocks that it
believes to be undervalued in relation to the issuer's assets, cash flow,
earnings and revenues. To decide whether or not these stocks are suitable for
investment, MSAM estimates the future value of these stocks using a mathematical
model, called a dividend discount model. MSAM uses research from a number of
sources, including Morgan Stanley Capital International, an affiliate located in
Geneva, Switzerland. Fund holdings are reviewed regularly, and analyzed to be
sure they continue to conform to MSAM's value criteria. Equity securities that
stop conforming to the Fund's investment criteria will be sold. Although the
Fund will not invest for short-term trading purposes, securities may be sold
that were held only for a short time.

Emerging Growth Fund
The Fund will usually invest at least 65% of its total assets in common stocks
or warrants of emerging growth companies that represent attractive opportunities
for maximum capital appreciation. Emerging growth companies are small- or
medium-sized companies beyond their start-up phase showing positive earnings or
the potential for accelerated earnings growth.

Although the Fund will typically invest in small and mid-sized companies, the
Fund may invest in emerging growth companies of any size. Emerging growth
companies generally benefit from new products or services, technological
developments, changes in management or other factors. The Fund may also invest
in companies experiencing unusual developments affecting their market value,
called "special situation" companies. These companies may be involved in
acquisitions or consolidations, reorganization, recapitalization, mergers,
liquidation, or distribution of cash, securities or other assets, tender or
exchange offers, a breakup or workout of a holding company, lawsuits which, if
resolved favorably, would improve the value of the company's stock, or a change
in corporate control.

The Fund may invest up to 20% of its total assets in investment grade debt
securities (other than money market obligations) and preferred stocks that are
not convertible into common stock. The Fund may also invest up to 20% of its
total assets in the securities of foreign issuers, which have certain risks
associated with them. The Fund's status is non-diversified , although its
portfolio managers have typically diversified the Fund's investments.

The interest income to be derived may be considered as one factor in selecting
debt securities for investment. Because the market value of debt obligations can
be expected to vary inversely with changes in prevailing interest rates,
investing in debt obligations may provide an opportunity for capital
appreciation when interest rates are expected to decline. The success of such a
strategy is dependent upon Warburg's ability to accurately forecast changes in
interest rates.

A security will be considered investment grade if it is rated within the four
highest grades by Moody's or S&P or, if unrated, is determined by Warburg to be
of comparable quality. Bonds rated in the fourth highest grade may have
speculative characteristics. If a security held by the Fund is no longer rated,
or is rated below the Fund's minimum allowed rating, Warburg factors this
information into the decision about whether the Fund should continue to hold the
securities. The Fund can normally invest up to 20% of its total assets in
domestic and foreign short-term money market obligations.

Investing in securities of emerging growth and small-sized companies can involve
greater risks because these securities may have limited marketability. Because
small and medium-sized companies normally have fewer shares outstanding than
larger companies, it may be more difficult for the Fund to buy or sell large
numbers of shares without affecting current prices. Small- and medium-sized
companies are typically subject to a greater degree of changes in earnings and
business prospects than are larger, more established companies. There is
typically less publicly available information concerning small- and medium-sized
companies than for larger, more established ones. And companies with small
market capitalizations may also be dependent upon a single proprietary product
or market niche, may have limited product lines, markets or financial resources,
or may depend on a limited management group.


                                                                              26
<PAGE>
 
Small/Mid Cap Fund
The Fund invests in equity securities, including common and preferred stocks,
and securities that can be converted into or exchanged for equity securities,
including warrants and rights. The Fund will typically invest in companies whose
securities are traded on domestic stock exchanges or in the over-the-counter
market.

Small companies are still in the developing stages of their life cycles and are
attempting to achieve rapid growth in both sales and earnings. The securities of
small companies may have limited marketability and may experience more abrupt or
erratic movements in price than securities of larger companies or the market
averages in general. Because of this, the net asset value of the Small/Mid Cap
Fund may fluctuate more widely than those of the popular market averages.

To give the Fund the flexibility to take advantage of new opportunities that can
help to meet the Fund's investment objectives, the Fund can invest up to 15% of
its net assets in money market instruments, bank and thrift obligations,
obligations issued or guaranteed by the U.S. Government or by its agencies or
instrumentalities, foreign bank obligations and obligations of foreign branches
of domestic banks, variable rate master demand notes and repurchase agreements.

The Fund may invest up to 20% of its total assets in foreign securities and will
be subject to certain risks as a result of these investments. The Fund may also
purchase American Depositary Receipts ("ADRs") or U.S. dollar-denominated
securities of foreign issuers that are not included in the 20% foreign
securities limitation.

Growth Equity Fund
At least 65% of the Fund's total assets will be invested in common stocks of
well-established, high-quality growth companies. The Fund may also invest in
convertible securities, preferred stocks, debentures and other corporate
obligations when Founders believes that these investments offer opportunities
for capital appreciation. Although these securities may produce current income,
income will not be a substantial factor in selecting these securities.

The Fund may invest in investment grade bonds, debentures and corporate
obligations rated Baa or higher by Moody's or BBB or higher by S&P. The Fund may
choose to invest in lower-rated (Ba or lower by Moody's and BB or lower by S&P)
convertible and preferred stocks but not rated below B. The Fund may also invest
in unrated convertible securities and preferred stocks if Founders believes that
they are equivalent in quality to the rated securities the Fund may buy.

The Fund will never have more than 5% of its total assets invested in unrated or
below-investment-grade fixed income securities, with the exception of preferred
stocks. If the Fund holds securities that are downgraded after they are
purchased, the Fund does not have to sell them unless the Fund assets in unrated
and blow investment-grade securities reaches 5% of total assets.

The Fund is also permitted to use forward foreign currency contracts and futures
contracts. The Fund may also purchase and/or write options on securities and on
indices, and may invest in Rule 144A securities.

Tax-Sensitive Equity Fund
This Fund is designed for investors in all but the lowest federal income tax
bracket seeking the highest long-term after-tax total return. The Fund tries to
minimize taxable dividend income by emphasizing securities with low dividend
yields and minimizing investments in income producing securities.

Usually, at least 80% of the Fund's total assets will be invested in equity and
equity-related securities, such as common stocks and preferred stocks. The Fund
may invest in equity securities of foreign issuers that are listed on a U.S.
securities exchange or traded in the U.S. over-the-counter market, but will not
invest more than 10% of its total assets in securities that are not listed or
traded. The Fund currently intends to limit its investments in foreign
securities to those that are denominated or quoted in U.S. dollars.

When selling portfolio securities, the Fund will generally select the highest
cost shares of the specific security (and/or, if gains will be realized, shares
that will produce long-term capital gains) in order to reduce the realization of
capital gains, short-term gains in particular. To help achieve its investment
objective, the Fund may sell securities in order to realize capital losses.
Realized capital losses can be used to offset realized capital gains, reducing
the amount of capital gains the Fund would distribute.

The Fund generally expects to have relatively low annual portfolio turnover
under normal circumstances, which is one way to help minimize taxable gains to
investors. For taxpayers in all but the lowest tax brackets, ordinary income is
taxed at a higher tax rate than capital gains on securities held for more than
one year ("long-term capital gains"). Ordinary income includes dividends from
the Fund's net investment income and net short-term capital gains. Net long-term
capital gains realized and distributed by the Fund are subject to federal taxes
as long-term capital gains. The Fund expects generally to hold appreciated
portfolio securities for more than one year. This holding period will reduce the
realization and distribution to shareholders of short-term capital gains, which
are taxed at higher ordinary income rates.

Although the Fund will always consider the impact of federal and state income
taxes on a shareholder's investment returns, portfolio management decisions may
be made based on other criteria, including actual or anticipated economic,
market or issuer-specific developments. In this case, the Fund may produce
taxable ordinary income. The Fund may occasionally need to sell securities it
would otherwise have held to generate cash, pay expenses or meet shareholder
redemption requests. Certain investments by the Fund may produce ordinary
taxable income on a regular basis.

As part of the strategy of reducing the impact of federal and state income taxes
paid by shareholders on Fund distributions, the Fund will follow a disciplined
investment strategy, emphasizing stocks that Standish believes to offer
above-average potential for capital growth while offering low dividend yields.
Although the precise application of the strategy will vary according to market
conditions, to identify attractive equity securities Standish intends to use
statistical modeling techniques that look at stock-specific factors. These
factors include: Current price/earnings ratios; stability of earnings growth;
forecasted changes in earnings growth; trends in consensus analysts' estimates;
and measures of earnings results relative to expectations. Once securities are
identified, fundamental analysis will be completed before they are included in
the Fund's holdings. Securities selected for inclusion in the Fund's portfolio
will represent various industries and sectors.


                                                                              28

Growth and Income Fund
Wellington Management seeks to achieve the Fund's objective by investing
primarily in a diversified portfolio of common stocks of U.S. issuers which
Wellington Management believes are of high quality. Wellington Management
believes that high quality companies is evidenced by a leadership position
within an industry, a strong or improving balance sheet, relatively high return
on equity, steady or increasing dividend payout, and strong management skills.
The Fund's investments will emphasize primarily dividend paying stocks of larger
companies The Fund may invest in securities that can be converted into, or that
include the right to buy common stocks, including convertible securities issued
in the Euromarket and preferred stocks. The Fund may also invest in marketable
debt securities of domestic issuers and of foreign issuers (payable in U.S.
dollars) rated at the time of purchase "A" or better by Moody's or S&P, or
unrated securities considered to be of equivalent quality in Wellington
Management's judgment. Under normal market conditions, the subadvisor expects
that the Fund's portfolio will consist primarily of equity securities.

Equity-Income Fund
The Fund will generally consider companies with the following characteristics:

o  established operating histories;
o  above-average current dividend yield relative to the average yield of the S&P
   500 Stock Index;
o  low price/earnings ratios relative to the S&P 500 Stock Index;
o  sound balance sheets and other financial characteristics; and
o  low stock price relative to a company's underlying value as measured by
   assets, earnings, cash flow, or business franchises.

The Fund will tend to take a "value" approach and invest in stocks and other
securities that appear to be temporarily undervalued by various measures, such
as price/earnings ratios. Value investors seek to buy a stock (or other
security) when its price is low in relation to what they believe to be its real
worth or future prospects. By identifying companies whose stocks are currently
out of favor, value investors hope to realize significant appreciation as other
investors recognize the stock's real value and the price rises accordingly.

The Fund may also buy bonds of any quality, including "junk bonds," preferred
stocks, convertible securities, and warrants, and may hold U.S.
dollar-denominated money market securities, including repurchase agreements, in
the two highest rating categories that mature in one year or less.

Balanced Fund
The Fund may invest in convertible securities, preferred stocks, bonds,
debentures, and other corporate obligations when Founders believes that these
investments offer opportunities for capital appreciation. Current income is also
a factor in the selection of these securities. The Fund may purchase convertible
securities and preferred stocks rated above B in medium and lower categories by
Moody's or S&P (Ba or lower by Moody's and BB or lower by S&P).

The Fund may invest without limit in ADRs and up to 30% of its total assets in
foreign securities (other than ADRs). The Fund will not invest more than 25% of
its total assets in the securities of any one foreign country. The Fund will be
subject to special risks as a result of its ability to invest up to 30% of its
total assets in foreign securities, excluding ADRs.

Strategic Income Fund
SBAM has entered into a subadvisory consulting agreement with its London-based
affiliate, Salomon Brothers Asset Management Limited ("SBAM Limited") under
which SBAM Limited provides certain advisory services to SBAM relating to
currency transactions and investments in non-dollar denominated debt securities.

The Fund may invest up to 100% of Fund assets in lower-rated securities usually
called "junk bonds." Junk bonds are rated "B" or below by Moody's (Moody's
lowest rating is C), or "BB" or below by S&P (S&P's lowest rating is D). If they
are unrated, SBAM will determine that they are of similar quality to rated
securities.

In addition to fundamental analysis, SBAM relies in part on mathematical,
quantitative analytical techniques that measure relative risks and opportunities
of each type of security. The techniques consider current and historical
economic, market, political and technical data for each type of security. SBAM
also assesses economic and market conditions on a global and local (country)
basis, including include current and projected levels of growth and inflation,
balance of payment status and monetary policy. SBAM also uses sophisticated
fixed income analysis tools, including prepayment analysis and option adjusted
spread technology to evaluate mortgage securities, mean variance optimization
models to evaluate international debt securities, and total rate of return
analysis to measure relative risks and opportunities in other fixed-income
markets.

Currency relationships and politics also impact the selection of international
debt securities. If the Fund is concerned about preserving capital, it may
choose to invest in securities that do not offer the highest possible yields.
SBAM continuously reviews how the Fund's assets are invested, and make s
appropriate adjustments. The Fund will invest in securities that range in
maturity.

The Fund may also invest in debt obligations issued or guaranteed by a foreign
sovereign government or one of its agencies or political subdivisions, and debt
obligations issued or guaranteed by international organizations designated or
supported by governmental entities to promote economic reconstruction or
development and international banking institutions and related government
agencies. Examples include the International Bank for Reconstruction and
Development (the "World Bank"), the European Coal and Steel Community, the Asian
Development Bank and the Inter-American Development Bank. These securities may
be denominated in multi-national currency units.

As discussed above, the Fund may invest in U.S. dollar-denominated securities
issued by domestic issuers that are rated below investment grade or, if unrated,
determined by SBAM to be of comparable quality Although SBAM does not plan to
invest more than 75% of the Fund's assets in below investment-grade domestic and
developing country debt securities, the Fund may choose to invest more than that
if SBAM feels that the yield available from such securities outweighs their
additional risks.

The purpose of investing a portion of the Fund's assets in below investment
grade, mortgage, and international debt securities, is to provide investors with
a higher yield than a high-quality domestic corporate bond fund, and with less
risk than a fund that invests principally in below investment grade securities.
Some of the debt securities the Fund may select may considered comparable to
securities having, the lowest ratings for non-subordinated debt instruments
assigned by Moody's or S&P (i.e., rated C by Moody's or CCC or lower by S&P).


                                                                              30

Investment Quality Bond Fund
The investment objective of the Fund is to provide a high level of current
income consistent with the maintenance of principal and liquidity. The Fund
invests primarily in a diversified portfolio of fixed income securities.

Credit research on corporate bonds includes examining both quantitative
(mathematical) and qualitative criteria established by Wellington Management.
These criteria include an issuer's industry, operating and financial profiles,
business strategy, management quality, and projected financial and business
conditions.

At least 65% of the Fund's assets will be invested in high quality debt
securities. "High quality" debt securities are those rated (at the time of
purchase) "A" or better by Moody's or S&P (in the three highest rating tiers),
or unrated debt securities considered to be of comparable quality by Wellington
Management. The Fund may only invest up to 20% of its total assets in debt
securities rated below "Baa" by Moody's or "BBB" by S&P, or unrated debt
securities considered to be of comparable quality by Wellington Management. The
Fund will not be required to sell any downgraded bonds that cause the Fund to
exceed this 20% minimum.

The Fund may invest up to 20% of its assets in domestic and foreign high yield
corporate and government debt securities, commonly referred to as "high
yield/high risk" or "junk" bonds. These bonds may be rated "B" or below by
Moody's (Moody's lowest rating is "C"), or "BB" or below by S&P (S&P's lowest
rating is "D"), or they may be unrated but considered to be of comparable
quality by Wellington Management. There is no minimum rating required by the
Fund. Domestic and foreign high yield debt securities involve greater risks than
higher quality securities, including price volatility and risk of default in the
payment of interest and principal.

National Municipal Bond Fund
The Fund's portfolio may include "moral obligation" securities, which are
normally issued by special purpose public authorities. If the issuer of moral
obligation securities cannot make its interest and principal payments from
current revenues, it may rely on a reserve fund. The availability of the reserve
fund is a moral commitment, but not a legal obligation, of the state or
municipality that created the issuer.

In addition, the Fund may invest in municipal lease obligations ("MLOs"). MLOs
are not fully backed by the municipality's credit and their interest may become
taxable if the lease is assigned, or sold to another lender. If timely lease
payments are not made, the lease will end, and it is possible that the MLO will
default and that the Fund will suffer a loss. Because SBAM plans to invest more
than 5% of the Fund's net assets in MLOs the Trustees of the Fund have
established procedures for SBAM to use in considering an investment in MLOs. The
factors SBAM must examine include:

o  the frequency of trades and quotes for the MLO
o  the number of dealers willing to purchase or sell such MLO and the number of
   other potential purchasers
o  the willingness of dealers to undertake to make a market in the MLO
o  the nature of the MLO and the nature of the marketplace trades (e.g., the
   time needed to dispose of the security and the method of soliciting offers)
o  the nature of the offering of such MLO (e.g., the size of the issue and the
   number of anticipated holders)
o  the ability of the MLO to maintain its marketability throughout the time the
   instrument is held in the Fund
o  other factors, if any, which SBAM deems relevant to determining the existence
   of a trading market for such MLO.

The Fund also may invest in resource recovery bonds, which may be general
obligations of the issuing municipality or supported by corporate or bank
guarantees. The viability of the resource recovery project, environmental
protection regulations and project operator tax incentives may affect the value
and credit quality of resource recovery bonds.

In order to maintain liquidity, the Fund may invest up to 20% of its total
assets in taxable obligations, including taxable high-quality short-term money
market instruments, including:

o  Obligations of the U.S. Government or its agencies or instrumentalities
o  Commercial paper of issuers rated at the time of purchase "A-2" or better by
   S&P, "P-2" or better by Moody's, or "F-2" or better by Fitch Investors
   Services, Inc., ("Fitch"), or unrated securities of similar quality
o  Certificates of deposit, bankers' acceptances or time deposits of U.S. banks
   with total assets of at least $1 billion (including obligations of foreign
   branches of such banks) and of the 75 largest foreign commercial banks in
   terms of total assets (including domestic branches of such banks), and
   repurchase agreements with respect to such obligations.

If at some point, SBAM determines that the market to securities exempt from
federal income taxes is troubled, the Fund may invest up to 100% of its net
assets taxable high-quality short-term money market instruments. Of course,
dividends paid by the Fund that are generated by taxable money market
instruments will be taxable to investors. From time to time, the Fund may invest
more than 25% of its total assets in obligations whose interest payments are
from revenues of similar projects (such as utilities or hospitals) or whose
issuers share the same geographic location. As a result, the Fund may be more
susceptible to a single economic, political or regulatory development than would
a Fund of securities with a greater variety of issuers.


                                                                              32

U.S. Government
Securities Fund
The Fund may invest in:

o  Mortgage-backed securities guaranteed by the Government National Mortgage
   Association ("GNMA"), popularly known as "Ginnie Maes," that are backed by
   the full faith and credit of the U.S.Government. These are known as a
   "modified pass through" type of mortgage-backed security ("GNMA
   Certificates"). These securities entitle the holder to receive all interest
   and principal payments due whether or not payments are actually made on the
   underlying mortgages
o  U.S. Treasury obligations
o  Obligations issued or guaranteed by agencies or instrumentalities of the U.S.
   Government. These securities are backed by their own credit, and may not be
   backed by the full faith and credit of the U.S. Government
o  Mortgage-backed securities guaranteed by agencies or instrumentalities of the
   U.S. Government which are supported by their own credit but not the full
   faith and credit of the U.S. Government, such as the Federal Home Loan
   Mortgage Corporation and the Federal National Mortgage Association;
o  Collateralized mortgage obligations issued by private issuers for which the
   underlying mortgage-backed securities serving as collateral are backed (i) by
   the credit alone of the U.S. Government agency or instrumentality which
   issues or guarantees the mortgage backed securities, or (ii) by the full
   faith and credit of the U.S. Government; and
o  Repurchase agreements collateralized by any of the foregoing.

Money Market Fund
The Fund invests in high quality, U.S. dollar-denominated money market
instruments including:

o  Obligations that are issued by or whose principal or interest is guaranteed
   by the U.S. Government. Obligations of any agency or authority controlled or
   supervised by and acting as an instrumentality of the U.S. Government under
   authority granted by Congress. These are called '"U.S. Government
   securities."'

o  Certificates of deposit, bank notes, time deposits, Eurodollars, Yankee
   obligations and bankers' acceptances of U.S. banks, foreign branches of U.S.
   banks, foreign banks and U.S. savings and loan associations which at the date
   of investment have capital, surplus and undivided profits as of the date of
   their most recent published financial statements in excess of $100,000,000
   (or less than $100,000,000 if the principal amount of such bank obligations
   is insured by the Federal Deposit Insurance Corporation ("FDIC") or the
   Savings Association Insurance Fund ("SAIF"))

o  Commercial paper which at the date of investment is rated (or guaranteed by a
   company whose commercial paper is rated) within the two highest rating
   categories by any nationally recognized statistical rating organization
   ("NRSRO") (such as "P-1" or "P-2" by Moody's or "A-1" or "A-2" by S&P) or, if
   not rated, is issued by a company which MAC, acting pursuant to guidelines
   established by the Trustees, has determined to be of minimal credit risk and
   comparable quality

o  Corporate obligations maturing in 397 days or less which at the date of
   investment are rated within the two highest rating categories by any NRSRO
   (such as "Aa" or higher by Moody's or "AA" or higher by S&P)

o  Short-term obligations issued by state and local governmental issuers

o  Obligations of foreign governments, including Canadian and Provincial
   Government and Crown Agency Obligations

o  Securities that have been structured to be eligible money market instruments
   such as participation interests in special purpose trusts that meet the
   quality and maturity requirements in whole or in part due to arrangements for
   credit enhancement or for shortening effective maturity

o  Repurchase agreements with respect to any of the foregoing obligations


                                                                              34

Other Risks of Investing in the North American Funds

Although a Fund may have the flexibility to use some or all of the investments
or strategies described in this Prospectus and the Statement of Additional
Information, its subadvisor may choose not to use these investments or
strategies for a variety of reasons. These choices may cause a Fund to miss
opportunities, lose money or not achieve its goal.

High Yield/High Risk Securities
High yield securities (often known as "junk bonds") include debt instruments
that have an equity security attached to them. Securities rated below investment
grade and comparable unrated securities offer yields that fluctuate over time,
but generally offer higher yields than do higher rated securities. However,
securities rated below investment grade also involve greater risks than higher
rated securities. Under rating agency guidelines, medium- and lower-rated
securities and comparable unrated securities will likely have some quality and
protective characteristics that are outweighed by large uncertainties or major
risk exposures to adverse conditions.

Some of the debt securities in which the Funds may choose to invest may be, or
may be similar to the lowest rated, (C by Moody's or CCC or lower by S&P)
non-subordinated debt. This type of security is very risky, as issuers may not
have the ability to repay principal and interest, and may even default. If this
should occur, the value of shares of the Fund holding them could fall.

Foreign Securities
There are risks associated with investing in foreign securities. These risks
include unforeseen changes in tax laws, political changes, and changes in
foreign currency values and exchange rates.

There may be less publicly available information about foreign issuers. Foreign
issuers, including foreign branches of U.S. banks, are subject to different
accounting and reporting requirements, which are generally less extensive than
the requirements for domestic issuers. Foreign stock markets generally have
substantially less volume than the U.S. exchanges and securities of foreign
issuers are generally less liquid and more volatile, relative to U.S. issuers.
For emerging markets, these risks can be more extreme.

There is frequently less governmental regulation of foreign exchanges,
broker-dealers and issuers than in the United States, and brokerage costs may be
higher. In addition, investments in foreign companies may be subject to the
possibility of nationalization or other changes in policy. Policy changes may
allow foreign governments to withhold dividends, expropriate (confiscate, or
keep) investment returns, or raise taxes to extremely high levels, among other
things. Also, should a foreign issuer default, it may be difficult to recover
anything in a bankruptcy proceeding.

Lending Fund Securities
Each Fund may lend up to 33% of its total portfolio assets, or securities, to
brokers, dealers and other financial institutions. These loans must be callable
(the Fund may ask that the loan be repaid in full) at any time by the Fund. The
loans must be at all times fully secured by cash, cash equivalents or securities
issued or guaranteed by the U.S. government or its agencies or
instrumentalities, and marked to market (priced at market value) to the value of
loaned securities on a daily basis. As with any extensions of credit, there may
be risks of delay in recovery and in some cases even loss of rights in the
collateral should the borrower of the securities fail financially. However,
these loans of Fund securities will only be made to firms deemed by the
subadvisors to be creditworthy.

Leverage Risk
Funds that borrow money to buy securities are using leverage. Leverage risk is
the risk that leverage, or debt, will enable a Fund to buy more of a security
that falls in value. In this case, the Fund's investment could fall, and the
Fund would still need to repay the money it borrowed. Funds can create leverage,
or borrow money, by using different types of techniques including reverse
repurchase agreements, dollar rolls, and derivatives including inverse floating
rate instruments.

Hedging and Other Strategic Transactions
Individual Funds may be authorized to use a variety of investment strategies
described below for hedging purposes only, including hedging various market
risks (such as interest rates, currency exchange rates and broad or specific
market movements), and managing the effective maturity or duration of debt
instruments held by the Fund. Hedging is simply believing that certain
securities will fall, or rise, in value, and structuring transactions that take
advantage of those changes. These transactions are generally used to protect
against possible changes in the market value of securities a Fund already owns
or plans to buy, to protect unrealized gains or to improve the Fund's return in
some way.

Where allowed, individual Funds may purchase and sell (or write) exchange-listed
and over-the-counter put and call options on securities, index futures
contracts, financial futures contracts and fixed-income indices and other
financial instruments, enter into financial futures contracts, enter into
interest rate transactions, and enter into currency transactions. This category
includes derivative transactions. A "derivative" is generally defined as an
instrument whose value is based upon, or derived from, some underlying index or
rate. Interest rate transactions may include swaps, caps, floors and collars,
and currency transactions may include currency forward contracts, currency
futures contracts, currency swaps and options on currencies or currency futures
contracts.

Year 2000
Year 2000 computer problems involve the inability of some computer systems to
properly process data-related information in respect to the end of this century.
While this problem could have a negative effect on the Funds, the advisor is
working to avoid this problem and obtain assurances from the subadvisors and
other service providers that they are adequately addressing any possible year
2000 problems. The year 2000 problem could also have a negative effect on
issuers whose securities are owned by the Funds, potentially decreasing the
value of such securities.

Euro Conversion
The conversion of certain European currencies to the Euro may present additional
risks to those Funds exposed to such currencies.

Frequent Trading
A Fund may buy or sell investments extremely frequently, increasing brokerage
commissions and other expenses of the Fund. Frequent trading may also increase
the amount of capital gains realized by a Fund, including short-term capital
gains, which are generally taxable to shareholders at ordinary income tax rates.

Temporary Defensive Strategies
A Fund's subadvisor may at certain times decide that pursuing the Fund's
investment strategies is inconsistent with market conditions. A subadvisor may
then employ defensive strategies designed mostly to limit losses. However, the
subadvisor may choose not to use defensive strategies, even in volatile or
unsettled market conditions. Such defensive strategies may cause the Fund to
miss opportunities or to not achieve its goal.

Class C Shares*
Class C shares are offered for sale at net asset value and are offered for
purchases of less than $1 million. Class C shares are sold without a front end
sales charge. Class C shares are subject to a deferred sales charge of 1% of the
dollar amount subject thereto during the first year after purchase.

Redemption in Kind
The Funds reserve the right to redeem proceeds in whole or in part by a
distribution in kind of marketable securities held by the Fund.

Payment Following Redemption
Each Fund will normally send the proceeds from a redemption (less any applicable
deferred sales charge) on the next business day, but may delay payment for up to
seven days.

Payment may be delayed if the shares to be redeemed were purchased by a check
that has not cleared. Each Fund may suspend the right of redemption and may
postpone payment for more than seven days when the New York Stock Exchange is
closed for other than weekends or holidays, or if permitted by the rules of, or
action by, the SEC.

* Any shares in the redeeming shareholder's account that can be redeemed without
  charge will be redeemed prior to those subject to a charge. Only time of
  ownership spent in Funds other than the Money Market Fund counts towards
  determining the applicable deferred sales charge.

value per share (next determined following receipt of an order) plus, in the
case of all Funds except the Money Market Fund, a front end sales charge, if
applicable. The share price for Class B shares and Class C shares is the net
asset value per share (next determined following receipt of an order).

The net asset value of the shares of each class of each Fund is calculated
separately and, except as described below, is determined once daily as of the
close of regularly scheduled trading on the New York Stock Exchange. Net asset
value per share of each class of each Fund (other than the Money Market Fund, as
described below) is calculated by dividing the value of the portion of the
Fund's securities and other assets attributable to that class, less the
liabilities attributable to that class, by the number of shares of that class
outstanding. No determination is required on (i) days on which changes in the
value of such Fund's securities holdings will not materially affect the current
net asset value of the shares of the Fund, (ii) days when the New York Stock
Exchange is closed (for example, national holidays). Generally, trading in
non-U.S. securities, as well as U.S.

Government securities and money market instruments, is substantially completed
each day at various times prior to the close of regularly scheduled trading on
the New York Stock Exchange. The values of such securities used in computing the
net asset value of the shares of a class of a Fund are generally determined as
of such times. Occasionally, events which affect the values of such securities
may occur between the times at which they are generally determined and the close
of regularly scheduled trading on the Exchange and would therefore not be
reflected in the computation of a class's net asset value. If events materially
affecting the value of such securities occur during such period, then these
securities will be valued at their fair value as determined in good faith by the
subadvisors under procedures established and regularly reviewed by the Trustees.

Shares of the Fund are available at the net asset value to investors purchasing
shares of the Funds with redemption proceeds from other mutual fund complexes on
which the investor has paid for front end sales charge or was subject to a
deferred sales charge, whether or not paid, if such redemption occurred more
than 60 days prior to such purchase. The Distributor will require satisfactory
evidence of your qualification of this waiver. Please call for more information.
The redemption of the shares from the other mutual fund is, for federal income
tax purposes, a sale upon which a gain or loss may be realized.

All instruments held by the Money Market Fund and short-term debt instruments
with a remaining maturity of 60 days or less held by the other Funds are valued
on an amortized cost basis.

Unless you request cash payment, all dividends and distributions will be
reinvested. All Funds except the Money Market Fund declare and pay capital gains
annually.

Taxes

It is expected that each Fund of the Trust will qualify as a "regulated
investment company" under the Code. If it so qualifies, a Fund will not be
subject to United States federal income taxes on its net investment income and
net capital gain, if any, that it distributes to its shareholders in each
taxable year, provided that it distributes to its shareholders (i) at least 90%
of its net investment income for such taxable year, and (ii) with respect to the
National Municipal Bond Fund at least 90% of its net tax-exempt interest income
for such taxable year. If in any year a Fund fails to qualify as a regulated
investment company, such Fund would incur regular corporate federal income tax
on its taxable income for that year and be subject to certain additional
distribution requirements upon re-qualification. Each Fund will be subject to a
4% nondeductible excise tax on its taxable income to the extent it does not meet
certain distribution requirements by the end of each calendar year. Each Fund
intends to make sufficient distributions to avoid application of the corporate
income and excise taxes. Funds investing in foreign securities or currencies may
be required to pay withholding or other taxes to foreign governments on
dividends and interest. The investment yield of the Funds investing in foreign
securities or currencies will be reduced by these foreign taxes. Shareholders
will bear the cost of any foreign taxes, but may not be able to claim a foreign
tax

credit or deduction for these foreign taxes. If a Fund is eligible for and makes
an election to allow the shareholders of that Fund to claim a foreign tax credit
or deduction for these taxes for any taxable year, the shareholders will be
notified. The ability of the shareholders to utilize such a foreign tax credit
is subject to a holding period requirement. In addition, Funds investing in
securities of passive foreign investment companies may be subject to U.S.
federal income taxes (and interest on such taxes) as a result of such
investments. The investment yield of the Funds making such investments will be
reduced by these taxes and interest. Shareholders will bear the cost of these
taxes and interest, but will not be able to claim a deduction for these amounts.

The redemption, sale or exchange of Fund shares (including the exchange of
shares of one Fund for shares of another) is a taxable event and may result in a
gain or loss. Gain or loss, if any, recognized on the sale or other disposition
of shares of the Fund will be taxed as capital gain or loss if the shares are
capital assets in the shareholder's hands. Generally, a shareholder's gain or
loss will be a long-term gain or loss if the shares have been held for more than
one year. Pursuant to the Taxpayer Relief Act of 1997, long-term capital gains
generally are subject to a maximum tax rate of 20%.

If a shareholder sells or otherwise disposes of a share of the Fund before
holding it for more than six months, any loss on the sale or other disposition
of such share shall be (i) treated as a long-term capital loss to the extent of
any capital gain dividends received by the shareholder with respect to such
share or (ii) in the case of the National Municipal Bond Fund, disallowed to the
extent of any exempt-interest dividend received by the shareholder with respect
to such shares. A loss realized on a sale or exchange of shares may be
disallowed if other shares are acquired within a 61-day period beginning 30 days
before and ending 30 days after the date on which the shares are disposed.

Generally, unless a shareholder of any Fund includes his or her taxpayer
identification number (social security number for individuals) in the
Shareholder Application and certifies that he or she is not subject to backup
withholding, the Fund is required to withhold and remit to the U.S. Treasury 31%
from dividends other than exempt-interest dividends and other reportable
payments to the shareholder.


                                                                              48

Depending on the residence of the shareholder for tax purposes, distributions
may also be subject to state and local taxes or withholding taxes. Most states
provide that a regulated investment company may pass through (without
restriction) to its shareholders state and local income tax exemptions available
to direct owners of certain types of U.S. government securities. Thus, for
residents of these states, distributions derived from a Fund's investment in
certain types of U.S. government securities should be free from state and local
income taxes to the extent that the interest income from such investments would
have been exempt from state and local income taxes if such securities had been
held directly by the respective shareholders themselves.

National Municipal Bond Fund--Taxation
The National Municipal Bond Fund also intends to satisfy conditions under the
Code that will enable interest from municipal obligations, which is exempt from
regular federal income taxes in the hands of each Fund, to qualify as
"exempt-interest dividends" when distributed to such Fund's shareholders. Except
as discussed below, such dividends are exempt from regular federal income taxes.
Although exempt-interest dividends paid by the National Municipal Bond Fund will
be excluded by shareholders of the Funds from their gross income for regular
federal income tax purposes, under the Code all or a portion of such dividends
may be (i) a preference item for purposes of the alternative minimum tax, (ii) a
component of the "ACE" adjustment for purposes of determining the amount of
corporate alternative minimum tax or (iii) a factor in determining the extent to
which a shareholder's Social Security or railroad retirement benefits are
taxable. Moreover, the receipt of exempt-interest dividends from each of the
Funds affect the federal tax liability of certain foreign corporations, S
Corporations and insurance companies. Furthermore, under the Code, interest on
indebtedness incurred or continued to purchase or carry Fund shares, which
interest is deemed to relate to exempt-interest dividends, will not be
deductible by shareholders of the Fund for federal income tax purposes.

The exemption of exempt-interest dividend income from regular federal income
taxation does not necessarily result in similar exemptions for such income under
tax laws of state or local taxing authorities. In general, states exempt from
state income tax only that portion of any exempt-interest dividend that is
derived from interest received by a regulated investment company on its holdings
of obligations issued by that state or its political subdivisions and
instrumentalities.

A notice detailing the tax status of dividends and distributions paid by the
National Municipal Bond Fund will be mailed annually to its shareholders. As
part of this notice, the Fund will report to its shareholders the percentage of
interest income earned by the Fund during the preceding year on tax-exempt
obligations indicating, on a state-by-state basis, the source of such income.

Descriptions of tax consequences set forth in this Prospectus and in the
Statement of Additional Information are intended to be a general guide.
Investors should consult their tax advisers with respect to the specific tax
consequences of an investment in a Fund, including the effect and applicability
of state, local, foreign, and other tax laws and the possible effects of changes
in federal or other tax laws. This discussion is not intended as a substitute
for careful tax planning.

Rule 12b-1 Fees

The Trust has adopted a distribution plan under Rule 12b-1 of the Investment
Company Act of 1940, as amended, that allows the Funds to pay distribution fees
for the sale and distribution of Fund shares. Portions of the fees are used to
provide payments for services provided to shareholders ("service fees"), as
indicated below.

Class A shares of each Fund, except the Money Market Fund and the National
Municipal Bond Fund, are subject to a fee of up to .35% of average daily net
assets, five-sevenths of which (.25%) is a "service fee." There are no Rule
12b-1 fees on the Money Market Fund, and the Rule 12b-1 fee paid by Class A
shares, or for the National Municipal Bond Fund is up to .15% of average annual
net assets, all of which is a "service fee." 

Class B shares of each Fund except the Money Market Fund are subject to a Rule
12b-1 fee of up to 1.00% of average annual net assets, one-fourth (.25%) of this
is a "service fee."

Class C shares of each Fund except the Money Market Fund are subject to a fee of
up to 1.00% of average annual net assets, one-fourth (.25%) of this is a
"service fee."

Because these fees are paid out of the Fund's assets on an ongoing basis, over
time they will increase the cost of your investment and may cost you more than
paying other types of sales charges. The higher fees for Class B and Class C
shares may therefore cost you more than paying the maximum permitted front-end
sales charge on Class A Shares.


                                                                              50

Account Services

To use any of these programs, simply fill out the appropriate section of your
account application, or request the appropriate form.

Automatic Dividend Diversification
With this program, you can have all dividends and other distributions from one
Fund automatically invested in the same class of shares of another Fund.

Automatic Investment Plan
Shareholders can set up an Automatic Investment Plan. Once each month the
shareholder's account will be debited the amount (at least $50) specified by the
shareholder.

Checkwriting
Checkwriting is available to Class A and Class C shareholders of the U.S.
Government Securities, National Municipal Bond and Money Market Funds. Simply
request this on your account application, and complete a signature card, and you
will receive a book of blank checks. The minimum amount of a check is $250. When
a check is presented for payment, enough shares will be redeemed to cover the
amount of the check and any applicable deferred sales charge. If the amount of
the check plus the sales charge is more than the account value, the check will
be returned unpaid.

Exchange Privilege
Shareholders may make free unlimited exchanges by mail or telephone within
classes of shares without any sales charge. Shares of one class may not be
exchanged for shares of any other class of any Fund. Be aware that exchanges are
regarded as sales for federal and state income tax purposes and could result in
a gain or loss, depending on the original cost of shares exchanged. Exchanges
usually occur on the same day they are requested. The terms of the exchange
privilege may change and the privilege may be revoked at any time without
notice.

The Fund will not be responsible for any losses resulting from unauthorized
telephone transactions if it follows reasonable procedures designed to varify
the identify of the caller. The Fund will request personal or other information
from the caller, and will record calls. By establishing an account with the
Fund, you consent to all recording of telephone calls.

You may make exchanges over the phone by calling 1-800-872-8037.

Reinstatement Privilege
If you redeem Class A shares (under $1 million) and reinvest within 90 days, you
will not have to pay a sales charge. If you redeem A shares over $1 million, or
Class B or C shares and pay a deferred sales charge and then reinvest within 90
days, your account will be credited the amount of the deferred sales charge.

Systematic Investing
Your shares of any class of the Money Market, U.S. Government Securities or
National Municipal Bond Fund can be exchanged monthly for shares of the same
class of other Funds. An exchange of at least $50 per exchange will be made
around the 15th of each month in accordance with your instructions. This program
takes advantage of dollar cost averaging.

Systematic Withdrawal Plan
If you have an account balance of at least $10,000, you can set up a plan to
have redemptions paid to you, or someone you designate, on a monthly, quarterly,
semi-annual or annual basis. You can withdraw up to 12% of the account value
annually, if a monthly plan, up to 1% per month, without a deferred sales
charge. If you request this service after completing your application and
payments are to be made to someone other than yourself, you will have to provide
a signature guarantee. Redemption checks are generally mailed within two days
after redemption. The availability of this service may end, and a fee of up to
$5 per withdrawal may be charged with 30 days written notice to you.

Transfer of Shares
You may transfer Fund shares to family members and others at any time without a
sales charge. Consult your tax adviser concerning such transfers.

Financial Highlights

The financial highlights tables are intended to help you understand each Fund's
financial performance for the past five years or, if shorter, the period of a
Fund's operations. Certain information reflects financial results for a single
Fund share. The Total returns in the tables represent the return that an
investor would have earned or lost on an investment in a Fund (assuming
reinvestment of all dividends and distributions). This information has been
audited by PricewaterhouseCoopers LLP, whose report, along with each Fund's
financial statements, is included in the Trust's annual report, which is
available upon request.
