Section I:
Fund Summaries



North American Funds (the "Trust") is 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 follow starting 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 are less than one year old).

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 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.

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 Dean Witter Investment
Management Inc. ("MSDW Investment Management"), the Fund's subadvisor, invests
in a globally diversified portfolio of equity securities.

MSDW Investment Management's investment focus is the selection of individual
stocks, with an eye toward value. To choose stocks for the Fund, MSDW Investment
Management 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, MSDW Investment Management 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.

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

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.

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:

 .  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.

 .  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:

 .  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.

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

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

The Fund may invest in derivatives.

Main Investing Risks
 . Derivatives Risk
 . Equity Risk, including particular risks associated Value stocks
 . Foreign Investment Risk
 . Management Risk

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,
pursues this objective by investing mostly in a diversified portfolio of common
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.

Equity-Income Fund
Investment Goal and Strategies



The investment objective of the Equity-Income Fund is to provide substantial
dividend income and also long term capital appreciation. To achieve this
objective, T. Rowe Price Associates, Inc. ("T. Rowe Price"), the Fund's

companies with favorable prospects for both increasing dividends and capital
appreciation.

Under normal circumstances, the Fund will invest at least 65% of total assets in
the common stocks of established companies paying above-average dividends. T.
Rowe Price believes that income can be a significant contributor to total return
over time and expects the Fund's dividend yield to be above that of the S&P 500
Stock Index. The Fund may invest in derivatives.

National Municipal Bond Fund
Investment Goal and Strategies


The investment objective of the National Municipal Bond Fund is to achieve a
high level of current income that is exempt from regular federal income taxes.
The Fund is also particularly concerned with preserving capital. To achieve
these goals, the Fund invests primarily in municipal debt. Salomon Brothers
Asset Management Inc. ("SBAM"), the Fund's subadvisor, manages the National
Municipal Bond Fund. Under normal circumstances, at least 80% of the Fund's net
assets will be invested in municipal debt securities whose interest payments are
exempt from regular federal income tax. Some of the Fund's dividends may be
subject to the federal alternative minimum tax.

The Fund will not purchase below investment-grade securities. Because the Fund
focuses on securities with long-term maturities, the average Fund maturity will
probably be 20 to 30 years, with an average duration of 8 to 11 years. The
Fund's portfolio may also include securities issued by municipalities that are
exempt from federal income tax. 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.

Descriptions of Main Investing Risks


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.



                                       17

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.

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:
 .  Invest $10,000 in a Fund for the time period indicated and then redeem all of
   your shares at the end of those periods.
 .  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, "ADR's"). ADR's 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. ADR's 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.

International Growth and Income Fund
The Fund is designed for investors with a long-term investment horizon who want
to take advantage of investment opportunities outside the United States.

The Fund invests primarily in the common stock of companies based in developed
markets other than the United States. However, the Fund may invest up to 15% of
its total assets in companies from emerging markets. The Fund may also invest in
other foreign securities with equity characteristics such as preferred stock,
warrants, rights and convertible securities.

The Fund invests in securities listed on foreign or domestic
securities exchanges and over-the-counter markets, and can invest
in certain restricted or unlisted securities. For the purposes of the Fund's
investments, developed countries include Australia, Canada, Japan, New Zealand,
the United Kingdom and most of the countries in eastern Europe. Emerging markets
include most other countries in the world.

In pursuing the Fund's objective, J.P. Morgan will actively manage the assets of
the Fund primarily through stock valuation and selection. Using fundamental
analysis as well as macro-economic models, J.P. Morgan develops proprietary
research on companies, countries and currencies. Using its fundamental stock
research, J.P. Morgan produces a ranking of companies in each industry group
according to their relative value. J.P. Morgan then buys and sells stocks, using
the research and valuation rankings as well as its assessment of other factors
it believes could affect a stock's price. The Fund emphasizes those stocks
ranked as undervalued, while underweighting or avoiding those that appear
overvalued. The Fund's country weightings primarily result from its stock
selection decisions and may differ significantly from it's benchmark, the MSCI
All Country World Index Free (ex-U.S.)

J.P. Morgan manages currency exposure, in conjunction with country and stock
allocation, in an attempt to protect and possibly enhance the Fund's market
value. Through the use of forward foreign currency exchange contracts, the Fund
may reduce its exposure to foreign currencies that J.P. Morgan deems
unattractive by selling the foreign currency in exchange for the U.S. dollar.
However, the Fund does not typically hedge its emerging markets equity exposure.

The Fund may make money market investments while seeking suitable investments,
waiting for settlement, or for liquidity purposes.

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.

MSDW Investment Management's investment focus is the selection of individual
stocks, with an eye toward value. To choose stocks for the Fund, MSDW Investment
Management 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, MSDW Investment Management estimates
the future value of these stocks using a mathematical model, called a dividend
discount model. MSDW Investment Management 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 MSDW Investment Management'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.

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 my 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.

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:
 . established operating histories;
 . above-average current dividend yield relative to the average yield of the S&P
  500 Stock Index;
 . low price/earnings ratios relative to the S&P 500 Stock Index;
 . sound balance sheets and other financial characteristics; and
 . 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," foreign
securities, preferred stocks, convertible securities, and warrants, and it will
hold some highly-rated U.S. and foreign dollar-denominated money market
securities, including repurchase agreements, in the two highest rating
categories, maturing 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 makes
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).

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.


                                       31
<PAGE>
 
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:

 .  the frequency of trades and quotes for the MLO
 .  the number of dealers willing to purchase or sell such MLO and the number of
   other potential purchasers
 .  the willingness of dealers to undertake to make a market in the MLO
 .  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)
 .  the nature of the offering of such MLO (e.g., the size of the issue and the
   number of anticipated holders)
 .  the ability of the MLO to maintain its marketability throughout the time
   the instrument is held in the Fund
 .  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:

 . Obligations of the U.S. Government or its agencies or instrumentalities
 . 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
 . 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.

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

 .  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
 .  U.S. Treasury obligations
 .  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
 .  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;
 .  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
 .  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:

 .  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."'
 .  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"))
 .  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
 .  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)
 .  Short-term obligations issued by state and local governmental issuers
 .  Obligations of foreign governments, including Canadian and Provincial
   Government and Crown Agency Obligations
 .  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
 .  Repurchase agreements with respect to any of the foregoing obligations

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.
Theloans 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.



                                       35

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.

Under an order granted to the Funds by the Securities and Exchange Commission,
CAM is permitted to appoint a subadvisor, to create a subadvisory agreement and
to terminate or amend a subadvisory agreement, in each case without shareholder
approval. This "Manager of Managers" structure permits the Funds to change
subadvisors or the fees paid to subadvisors without the expense and delays
associated with obtaining shareholder approval. CAM has ultimate responsibility
under the Manager of Managers structure to oversee the subadvisors, including
making recommendations to the Trust regarding the hiring, termination and
replacement of subadvisors.

Subadvisory Arrangements


CAM contracts with and compensates ten investment subadvisors which provide
portfolio management services to all of the Funds:


Wellington Management Company, LLP
Wellington Management Company, LLP, the subadvisor to the Growth and Income and
Investment Quality Bond Funds, ("Wellington Management"), whose principal
business address is 75 State Street, Boston, Massachusetts 02109.

Wellington Management and its predecessor organizations have provided investment
management services to investment companies, employee benefit plans, endowments,
foundations and other institutions and individuals since 1928. As of September
30, 1998, Wellington Management had investment management authority with respect
to approximately $186.5 billion of assets.

Matthew E. Megargel, Senior Vice President of Wellington Management, has served
as fund manager to the Growth and Income Fund since February 1992. Mr. Megargel
joined Wellington Management in 1983 as a research analyst and took on

   Distributor. Purchases of $1 million or more for each shareholder account
   will be aggregated over a 12 month period (commencing from the date of the
   first such purchase) for purposes of determining the level of commission to
   be paid during that period with respect to such account.

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 CDSC 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
Back End 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.

Pricing of Fund Shares

The public offering price of the Class A shares of each Fund is the net asset
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.

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
and dividends 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 28% or 20% depending on the
shareholder's holding period in shares of a Fund. 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.

<PAGE>
 
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 to it 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.

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 use all dividends and other distributions from one
Fund automatically invested in another Fund of the same class of shares.

Automatic Investment Plan
Shareholders can set up an Automatic Investment Plan. Once each month the
transfer agent will debit the shareholder's bank account the amount (at least
$50) specified by the shareholder. To stop the plan, give 30 days written notice
to the Transfer Agent. The program will stop if a shareholder's bank does not
honor a debit.

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 back end load. If the amount of the check
plus the load 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.

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 back end load and then reinvest within 90 days,
your account will be credited the amount of the back end load.

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, up to 1% per month, without a back end load. 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.

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 Fund's annual report, which is
available upon request.

                          HISTORY AND CLASSIFICATION

     The Fund is an open-end, management investment company organized as a
business trust under the laws of the Commonwealth of Massachusetts on September
28, 1988.

     All of the Funds, except the Emerging Growth Fund, are "diversified" for
purposes of the Investment Company Act of 1940.

     None of the Funds is a "commodity pool" (i.e., a pooled investment vehicle
which trades in commodity futures contracts and options thereon and the operator
of which is registered with the Commodity Futures Trading Commission (the
"CFTC")). Futures contracts and options on futures contracts will be purchased,
sold or entered into only for bona fide hedging to the extent permitted by CFTC
regulations. The use of certain Hedging and Other Strategic Transactions will
require that a Fund segregate cash or other liquid assets to the extent a Fund's
obligations are not otherwise "covered" through ownership of the underlying
security, financial instrument or currency.

                         INVESTMENT POLICIES AND RISKS

     The following discussion supplements the descriptions of certain of the
Funds and their possible investments and associated risks, as set forth in the
Prospectus. Although the Funds may have the flexibility to use some or all of
the investments and strategies described in the Prospectus and in this SAI, the
subadvisers may choose not to use such investments or strategies for a variety
of reasons. These choices may cause a Fund to miss opportunities, lose money or
not achieve its objective.

TAX-SENSITIVE EQUITY FUND

     Although the Fund will prefer long-term capital gains to taxable dividend
income and interest income, the Fund may to a limited extent invest in debt
securities and preferred stocks that are convertible into, or exchangeable for,
common stocks. Generally, such securities will be rated, at the time of
investment, Aaa, Aa or A by Moody's of AAA, AA or A by S&P or, if not rated, are
determined by Standish to be of comparable credit quality. Up to 5% of the
Fund's total assets invested in convertible debt securities and preferred stocks
may be rated, at the time of investment, Baa by Moody's or BBB by S&P or, if not
rated, determined by Standish to be of comparable credit quality. As a temporary
matter and for defensive purposes, the Fund may purchase investment grade short-
term debt securities, the amount of which will depend on market conditions and
the needs of the Fund. The Fund will attempt to reduce risk by diversifying its
investments within the investment policy set forth above.

     The Fund may, but is not required to, utilize various investment strategies
and techniques to seek to hedge various market risks (such as broad or specific
equity market movements and currency exchange rate risks) or to seek to enhance
potential gain. Such strategies and techniques are generally accepted as part of
modern portfolio management and are regularly utilized by many mutual funds. In
the course of pursuing its investment objective, the Fund may: (i) purchase and
write (sell) put and call options on securities, equity indices and other
financial instruments; (ii) purchase and sell financial futures contracts on
U.S. equity indices and options thereon; (iii) enter into repurchase agreements;
(iv) enter into various currency transactions, such as currency forward
contracts, currency futures contracts, currency swaps or options on currencies
or currency futures (the Fund has no current intention to engage in such
transactions); and (v) make short sales. These techniques may produce taxable
ordinary income and/or short-term or long-term capital gains. Although the Fund
does not normally invest in equity securities that are restricted as to
disposition by federal securities laws or are otherwise illiquid, the Fund may
so invest up to 15% of its net assets when, in the opinion of Standish,
investment opportunities presented by such securities are particularly
attractive.

INTERNATIONAL SMALL CAP FUND

     The Fund may invest in securities issued by companies located in countries
not considered to be major industrialized nations. Such countries are subject to
more economic, political and business risk than major industrialized nations,
and the securities issued by those companies may be more volatile, less liquid
and more uncertain as to payment of dividends, interest and principal.
Additionally, investments of the Fund may include securities created through the
Brady Plan, a program under which heavily indebted countries have restructured
their bank debt into bonds.

GROWTH EQUITY FUND

     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 that 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 total Fund assets in
unrated and below investment-grade securities reaches 5% of assets.

                                      -3-
<PAGE>
 
     The Fund is also permitted to use forward foreign currency contracts and
futures contracts.  The Fund may also purchase and/or write option on securities
and on indices, and may invest in Rule 144A securities.

INVESTMENT QUALITY BOND

     Subject to the investment quality limitations discussed in the Prospectus,
the Fund is authorized to invest in domestic and foreign debt securities rated
(at the time of purchase) below "A" by Moody's or S&P (or unrated debt
securities considered to be of comparable quality by Wellington Management). The
Fund is also authorized to invest in preferred stocks, convertible securities
(including those issued in the Euro market) and securities carrying warrants to
purchase equity securities, privately placed debt securities, asset-backed
securities and privately issued mortgage securities.

INTERNATIONAL GROWTH AND INCOME FUND

     The Fund intends to manage its portfolio actively in pursuit of its
investment objective. The Fund does not expect to trade in securities for short-
term profits; however, when circumstances warrant, securities may be sold
without regard to the length of time held.

     The Fund may invest in securities on a when-issued or delayed delivery
basis, enter into repurchase and reverse repurchase agreements, loan its Fund
securities and purchase certain privately placed securities.

EQUITY-INCOME FUND

     The Fund may invest in debt securities of any type including municipal
securities without regard to quality or rating. The total return and yield of
lower-quality (high-yield/high-risk) bonds, commonly referred to as "junk"
bonds, can be expected to fluctuate more than the total return and yield of
higher-quality, shorter-term bonds, but not as much as common stocks. Junk bonds
(those rated below BBB or in default) are regarded as predominantly speculative
with respect to the issuer's continuing ability to meet principal and interest
payments. The Fund will not purchase a noninvestment-grade debt security (or
junk bond) if immediately after such purchase the Fund would have more than 10%
of its total assets invested in such securities.

     The Fund may also engage in a variety of investment management practices,
such as buying and selling futures and options. The Fund may invest up to 10% of
its total assets in hybrid instruments, which are a type of high-risk derivative
which can combine the characteristics of securities, futures and options. For
example, the principal amount, redemption or conversion terms of a security
could be related to the market price of some commodity, currency or securities
index. Such securities may bear interest or pay dividends at below market (or
even relatively nominal) rates.

BALANCED FUND

     The Fund may invest in unrated convertible securities and preferred stocks
in instances in which the subadviser believes that the financial condition of
the issuer or the protection afforded by the terms of the securities limits risk
to a level similar to that of securities eligible for purchase by the Fund rated
in categories no lower than B. At no time will the Fund have more than 5% of its
total assets invested in any fixed-income securities which are unrated or are
rated below investment grade either at the time of purchase or as a result of a
reduction in rating after purchase. Preferred stocks are not subject to this 5%
limitation. The Fund is not required to dispose of debt securities whose ratings
are downgraded below these ratings subsequent to the Fund's purchase of the
securities, unless such a disposition is necessary to reduce the Fund's holdings
of such securities to less than 5% of its total assets.

STRATEGIC INCOME FUND

     In light of the risks associated with high yield corporate and sovereign
debt securities, the subadviser will take various factors into consideration in
evaluating the creditworthiness of an issuer. For corporate debt securities,
these will typically include the issuer's financial resources, its sensitivity
to economic conditions and trends, the operating history of the issuer, and the
experience and track record of the issuer's management. For sovereign debt
instruments, these will typically include the economic and political conditions
within the issuer's country, the issuer's overall and external debt levels and
debt service ratios, the issuer's access to capital markets and other sources of
funding, and the issuer's debt service payment history. The subadviser will also
review the ratings, if any, assigned to the security by any recognized rating
agencies, although the subadviser's judgment as to the quality of a debt
security may differ from that suggested by the rating published by a rating
service. The Fund's ability to achieve its investment objective may be more
dependent on the subadviser's credit analysis than would be the case if it
invested in higher quality debt securities.

     The high yield sovereign debt securities in which the Fund may invest are
U.S. dollar-denominated and non-dollar-denominated debt securities, including
Brady Bonds, that are issued or guaranteed by governments or governmental
entities of developing and emerging countries. The subadviser expects that these
countries will consist primarily of those which have issued or have announced
plans to issue Brady Bonds, but the Fund is not limited to investing in the debt
of such countries. The subadviser anticipates that the Fund's initial
investments in sovereign debt will be concentrated in Latin American countries,
including Mexico 

                                      -4-
<PAGE>
 
and Central and South American and Caribbean countries. The subadviser expects
to take advantage of additional opportunities for investment in the debt of
North African countries, such as Nigeria and Morocco, Eastern European
countries, such as Poland and Hungary, and Southeast Asian countries, such as
the Philippines. Sovereign governments may include national, provincial, state,
municipal or other foreign governments with taxing authority. Governmental
entities may include the agencies and instrumentalities of such governments, as
well as state-owned enterprises.

NATIONAL MUNICIPAL BOND FUND

     The types of obligations in which the Fund may invest include the
following:

     MUNICIPAL BONDS. The Fund may invest in municipal bonds that are rated at
the time of purchase within the four highest ratings assigned by Moody's, S&P or
Fitch, or determined by SBAM to be of comparable quality. The four highest
ratings currently assigned by Moody's to municipal bonds are "Aaa", "Aa", "A"
and "Baa"; the four highest ratings assigned by S&P and Fitch to municipal bonds
are "AAA", "AA", "A" and "BBB". A more complete description of the debt security
ratings used by the Fund assigned by Moody's, S&P and Fitch is included in
Appendix I to this Prospectus.

     Although municipal obligations rated in the fourth highest rating category
by Moody's (i.e., "Baa") or S&P or Fitch (i.e., "BBB") are considered investment
grade, they may be subject to greater risks than other higher rated investment
grade securities. Municipal obligations rated "Baa" by Moody's, for example, are
considered medium grade obligations that lack outstanding investment
characteristics and have speculative characteristics as well. Municipal
obligations rated "BBB" by S&P and Fitch are regarded as having an adequate
capacity to pay principal and interest.

     Municipal bonds are debt obligations that are typically issued to obtain
funds for various public purposes, such as construction of public facilities
(e.g., airports, highways, bridges and schools). Municipal bonds at the time of
issuance are generally long-term securities with maturities of as much as twenty
years or more, but may have remaining maturities of shorter duration at the time
of purchase by the Fund.

     MUNICIPAL NOTES. The Fund may invest in municipal notes rated at the time
of purchase "MIG1", "MIG2" (or "VMIG-1" or "VMIG-2", in the case of variable
rate demand notes), "P-2" or better by Moody's, "SP-2", "A-2" or better by S&P,
or "F-2" or better by Fitch, or if not rated, determined by SBAM to be of
comparable quality.

     Municipal notes are issued to meet the short-term funding requirements of
local, regional and state governments. Municipal notes generally have maturities
at the time of issuance of three years or less. Municipal notes that may be
purchased by the Fund include, but are not limited to:

     TAX ANTICIPATION NOTES. Tax anticipation notes ("TANs") are sold as interim
financing in anticipation of collection of taxes. An uncertainty in a municipal
issuer's capacity to raise taxes as a result of such factors as a decline in its
tax base or a rise in delinquencies could adversely affect the issuer's ability
to meet its obligations on outstanding TANs.

     BOND ANTICIPATION NOTES.   Bond anticipation notes ("BANs") are sold as
interim financing in anticipation of a bond sale. The ability of a municipal
issuer to meet its obligations on its BANs is primarily dependent on the
issuer's adequate access to the longer term municipal bond market and the
likelihood that the proceeds of such bond sales will be used to pay the
principal of, and interest on, BANs.

     REVENUE ANTICIPATION NOTES.   Revenue anticipation notes ("RANs") are sold
as interim financing in anticipation of receipt of other revenues. A decline in
the receipt of certain revenues, such as anticipated revenues from another level
of government, could adversely affect an issuer's ability to meet its
obligations on outstanding RANs.

     TANs, BANs and RANs are usually general obligations of the issuer.

     MUNICIPAL COMMERCIAL PAPER. The Fund may also purchase municipal commercial
paper that is rated at the time of purchase "P-2" or better by Moody's, "A-2" or
better by S&P, or "F-2" or better by Fitch, or if not rated, determined by SBAM
to be of comparable quality.

     Municipal commercial paper that may be purchased by the Fund consists of
short term obligations of a municipality. Such paper is likely to be issued to
meet seasonal working capital needs of a municipality or as interim construction
financing. Municipal commercial paper, in many cases, is backed by a letter of
credit lending agreement, note repurchase agreement or other credit facility
agreement offered by banks or other institutions.

     MUNICIPAL LEASE OBLIGATIONS

                                      -5-
<PAGE>
 
     The Fund may invest in municipal lease obligations. Municipal lease
obligations are secured by revenues derived from the lease of property to state
and local government units. The underlying leases typically are renewable
annually by the governmental user, although the lease may have a term longer
than one year. If the governmental user does not appropriate sufficient funds
for the following year's lease payments, the lease will terminate, with the
possibility of default on the lease obligations and significant loss to the
Fund. In the event of a termination, assignment or sublease by the governmental
user, the interest paid on the municipal lease obligation could become taxable,
depending upon the identity of the succeeding user.

     MUNICIPAL BOND INDEX FUTURES CONTRACTS

     The Fund may enter into municipal bond index futures contracts. A municipal
bond index futures contract is an agreement to take or make delivery of an
amount of cash equal to the difference between the value of the index at the
beginning and at the end of the contract period. The Fund may enter into short
municipal bond index futures contracts in anticipation of or during a market
decline to attempt to offset the decrease in market value of securities in its
respective portfolio that might otherwise result. When the Fund is not fully
invested in securities and anticipates a significant market advance, it may
enter into long municipal bond index futures contracts in order to gain rapid
market exposure that may wholly or partially offset increases in the costs of
securities that it intends to purchase. In a substantial majority of these
transactions, the Fund will purchase such securities upon termination of the
futures position but, under unusual market conditions, a futures position may be
terminated without the corresponding purchase of securities.

     CHARACTERISTICS OF MUNICIPAL OBLIGATIONS.   Municipal obligations are debt
obligations issued by or on behalf of states, cities, municipalities and other
public authorities. The two principal classifications of municipal obligations
that may be held by the Fund are "general obligation" securities and "revenue"
securities. General obligation securities are secured by the issuer's pledge of
its full faith, credit and taxing power for the payment of principal and
interest. Revenue securities are payable only from the revenues derived from a
particular facility or class of facilities or, in some cases, from the proceeds
of a special excise tax or other specific revenue source such as the user of a
facility being financed. Revenue securities may include private activity bonds.
Such bonds may be issued by or on behalf of public authorities to finance
various privately operated facilities and are not payable from the unrestricted
revenues of the issuer. As a result, the credit quality of private activity
bonds is frequently related directly to the credit standing of private
corporations or other entities. In addition, the interest on private activity
bonds issued after August 7, 1986 is subject to the federal alternative minimum
tax. The Fund will not be restricted with respect to the proportion of its
assets that may be invested in such obligations. Accordingly, the Fund may not
be a suitable investment vehicle for individuals or corporations that are
subject to the federal alternative minimum tax.

     Opinions relating to the validity of municipal obligations and to the
exemption of interest thereon from regular federal income tax are rendered by
bond counsel to the respective issuers at the time of issuance. Neither the Fund
nor SBAM will review the proceedings relating to the issuance of municipal
obligations or the basis for such opinions.

     ADDITIONAL INVESTMENT ACTIVITIES.   Floating and Variable Rate Obligations.
Certain of the obligations that the Fund may purchase may have a floating or
variable rate of interest. Floating or variable rate obligations bear interest
at rates that are not fixed, but vary with changes in specified market rates or
indices, such as the prime rate, and at specified intervals. Certain of the
floating or variable rate obligations that may be purchased by the Fund may
carry a demand feature that would permit the holder to tender them back to the
issuer of the underlying instrument or to a third party at par value prior to
maturity. Such obligations include variable rate demand notes, which are
instruments issued pursuant to an agreement between the issuer and the holder
that permit the indebtedness thereunder to vary and provide for periodic
adjustments in the interest rate.

     PARTICIPATION CERTIFICATES. The instruments that may be purchased by the
Fund include participation certificates issued by a bank, insurance company or
other financial institution in obligations owned by such institutions or
affiliated organizations that may otherwise be purchased by the Fund. A
participation certificate gives the Fund an undivided interest in the underlying
obligations in the proportion that the Fund's interest bears to the total
principal amount of such obligations. Certain of such participation certificates
may carry a demand feature that would permit the holder to tender them back to
the issuer or to a third party prior to maturity.

     VARIABLE RATE AUCTION SECURITIES AND INVERSE FLOATERS. The Fund may invest
in variable rate auction securities and inverse floaters which are instruments
created when an issuer or dealer separates the principal portion of a long-term,
fixed-rate municipal bond into two long-term, variable-rate instruments. The
interest rate on the variable rate auction portion reflects short-term interest
rates, while the interest rate on the inverse floater portion is typically
higher than the rate available on the original fixed-rate bond. Changes in the
interest rate paid on the portion of the issue relative to short-term interest
rates inversely affect the interest rate paid on the latter portion of the
issue. The latter portion therefore is subject to greater price volatility than
the original fixed-rate bond. Since the market for these instruments is new, the
holder of one portion may have difficulty finding a ready purchaser. Depending
on market availability, the two portions may be recombined to form a fixed-rate
municipal bond.

     USE OF HEDGING AND OTHER STRATEGIC TRANSACTIONS. The Fund is currently
authorized to use only certain hedging and other strategic transactions.
Specifically, the Fund may purchase or sell futures contracts on (a) debt
securities that are backed by the full faith and credit of the U.S. Government,
such as long-term U.S. Treasury Bonds and Treasury Notes and (b) municipal bond
indices. 

                                      -6-
<PAGE>
 
Currently, at least one exchange trades futures contracts on an index of long-
term municipal bonds, and the Fund reserves the right to conduct futures
transactions based on an index which may be developed in the future to correlate
with price movements in municipal obligations. It is not presently anticipated
that any of these strategies will be used to a significant degree by the Fund.

U.S. GOVERNMENT SECURITIES FUND

     The mortgage-backed securities in which the Fund invests represent
participating interests in pools of residential mortgage loans which are
guaranteed by the U.S. Government, its agencies or instrumentalities of the U.S.
Government. However, the guarantee of these types of securities runs only to the
principal and interest payments and not to the market value of such securities.
In addition, the guarantee only runs to the Fund securities held by the U.S.
Government Securities Fund and not to the purchase of shares of the Fund.

     Mortgage-backed securities are issued by lenders such as mortgage bankers,
commercial banks, and savings and loan associations. Such securities differ from
conventional debt securities which provide for periodic payment of interest in
fixed amounts (usually semiannually) with principal payments at maturity or
specified call dates. Mortgage-backed securities provide monthly payments which
are, in effect, a "pass-through" of the monthly interest and principal payments
(including any prepayments) made by the individual borrowers on the pooled
mortgage loans. Principal prepayments result from the sale of the underlying
property or the refinancing or foreclosure of underlying mortgages.

     The yield of mortgage-backed securities is based on the average life of the
underlying pool of mortgage loans, which is computed on the basis of the
maturities of the underlying instruments. The actual life of any particular pool
may be shortened by unscheduled or early payments of principal and interest. The
occurrence of prepayments is affected by a wide range of economic, demographic
and social factors and, accordingly, it is not possible to accurately predict
the average life of a particular pool. For pools of fixed rate 30-year
mortgages, it has been common practice to assume that prepayments will result in
a 12-year average life. The actual prepayment experience of a pool of mortgage
loans may cause the yield realized by the Fund to differ from the yield
calculated on the basis of the average life of the pool. In addition, if any of
these mortgage-backed securities are purchased at a premium, the premium may be
lost in the event of early prepayment which may result in a loss to the Fund.

     Prepayments tend to increase during periods of falling interest rates,
while during periods of rising interest rates prepayments will most likely
decline. Reinvestment by the Fund of scheduled principal payments and
unscheduled prepayments may occur at higher or lower rates than the original
investment, thus affecting the yield of the Fund. Monthly interest payments
received by the Fund have a compounding effect which will increase the yield to
shareholders as compared to debt obligations that pay interest semiannually.
Because of the reinvestment of prepayments of principal at current rates,
mortgage-backed securities may be less effective than Treasury bonds of similar
maturity at maintaining yields during periods of declining interest rates. Also,
although the value of debt securities may increase as interest rates decline,
the value of these pass-through type of securities may not increase as much due
to the prepayment feature.

     While the Fund seeks a high level of current income, it cannot invest in
instruments such as lower grade corporate obligations which offer higher yields
but are subject to greater risks. The Fund will not knowingly invest in a high
risk mortgage security. The term "high risk mortgage security" is defined
generally as any mortgage security that exhibits greater price volatility than a
benchmark security, the Federal National Mortgage Association current coupon 30-
year mortgage-backed pass through security. Shares of the Fund are neither
insured nor guaranteed by the U.S. Government, its agencies or
instrumentalities.

     In order to make the Fund an eligible investment for federal credit unions
("FCUs"), federal savings and loan institutions and national banks, the Fund
will invest in U.S. Government securities that are eligible for investment by
such institutions without limitation, and will also generally be managed so as
to qualify as an eligible investment for such institutions. The Fund will comply
with all investment limitations applicable to FCUs including (i) the requirement
that a FCU may only purchase collateralized mortgage obligations which would
meet the high risk securities test of Part 703 of the National Credit Union
Administration Rules and Regulations or would be held solely to reduce interest
rate risk and (ii) the requirement that a FCU may not purchase zero coupon
securities having maturities greater than ten years.

MONEY MARKET FUND

     Commercial paper may include variable amount master demand notes, which are
obligations that permit investment of fluctuating amounts at varying rates of
interest. Such notes are direct lending arrangements between the Fund and the
note issuer, and MAC will monitor the creditworthiness of the issuer and its
earning power and cash flow, and will also consider situations in which all
holders of such notes would redeem at the same time. Variable amount master
demand notes are redeemable on demand.

     The Fund will invest only in U.S. dollar-denominated instruments. All of
the Fund's investments will mature in 397 days or less and the Fund will
maintain a dollar-weighted average fund maturity of 90 days or less. By limiting
the maturity of its investments, the Fund seeks to lessen the changes in the
value of its assets caused by fluctuations in short-term interest rates. Due to
the short maturities of its investments, the Fund will tend to have a lower
yield than, and the value of its underlying investments will be less 

                                      -7-
<PAGE>
 
volatile than the investments of, funds that invest in longer-term securities.
In addition, the Fund will invest only in securities the Trustees determine to
present minimal credit risks and which at the time of purchase are "eligible
securities" as defined by Rule 2a-7 under the 1940 Act. Generally, eligible
securities must be rated by a NRSRO in one of the two highest rating categories
for short-term debt obligations or be of comparable quality.

           INVESTMENTS AND RISK FACTORS APPLICABLE TO MULTIPLE FUNDS

MONEY MARKET INSTRUMENTS

     The Money Market Fund will be invested in the types of money market
instruments described below. Certain of the instruments listed below may also be
purchased by the other Funds in accordance with their investment policies and
certain Funds may purchase such instruments to invest otherwise idle cash or for
defensive purposes.

     1.   U.S. Government and Government Agency Obligations. U.S. Government
obligations are debt securities issued or guaranteed as to principal or interest
by the U.S. Treasury. These securities include treasury bills, notes and bonds.
U.S. Government agency obligations are debt securities issued or guaranteed as
to principal or interest by an agency or instrumentality of the U.S. Government
pursuant to authority granted by Congress. U.S. Government agency obligations
include, but are not limited to, the Student Loan Marketing Association, Federal
Home Loan Banks, Federal Intermediate Credit Banks and the Federal National
Mortgage Association. U.S. instrumentality obligations include, but are not
limited to, the Export-Import Bank and Farmers Home Administration. Some
obligations issued or guaranteed by U.S. Government agencies or
instrumentalities are supported by the right of the issuer to borrow from the
U.S. Treasury or the Federal Reserve Banks, such as those issued by Federal
Intermediate Credit Banks; others, such as those issued by the Federal National
Mortgage Association, are supported by discretionary authority of the U.S.
Government to purchase certain obligations of the agency or instrumentality; and
others, such as those issued by the Student Loan Marketing Association, are
supported only by the credit of the agency or instrumentality. There are also
separately traded interest components of securities issued or guaranteed by the
U.S. Treasury. No assurance can be given that the U.S. Government will provide
financial support to such U.S. Government sponsored agencies or
instrumentalities in the future, since it is not obligated to do so by law. The
foregoing types of instruments are hereafter collectively referred to as "U.S.
Government securities."

     2.   Certificates of Deposit and Bankers' Acceptances. Certificates of
deposit are certificates issued against funds deposited in a bank or a savings
and loan association. They are for a definite period of time and earn a
specified rate of return. Bankers' acceptances are short-term credit instruments
evidencing the obligation of a bank to pay a draft which has been drawn on it by
a customer. These instruments reflect the obligation both of the bank and of the
drawer to pay the face amount of the instrument upon maturity. They are
primarily used to finance the import, export, transfer or storage of goods. They
are termed "accepted" when a bank guarantees their payment at maturity.

     Fund Portfolios may acquire obligations of foreign banks and foreign
branches of U.S. banks. These obligations are not insured by the Federal Deposit
Insurance Corporation.

     3.   Commercial Paper. Commercial paper consists of unsecured promissory
notes issued by corporations to finance short-term credit needs. Commercial
paper is issued in bearer form with maturities generally not exceeding nine
months. Commercial paper obligations may include variable amount master demand
notes. Variable amount master demand notes are obligations that permit the
investment of fluctuating amounts at varying rates of interest pursuant to
direct arrangements between a Fund, as lender, and the borrower. These notes
permit daily changes in the amounts borrowed. A Fund has the right to increase
the amount under the note at any time up to the full amount provided by the note
agreement, or to decrease the amount, and the borrower may prepay up to the full
amount of the note without penalty. Because variable amount master demand notes
are direct lending arrangements between the lender and borrower, it is not
generally contemplated that such instruments will be traded, and there is no
secondary market for these notes, although they are redeemable (and thus
immediately repayable by the borrower) at face value, plus accrued interest, at
any time. A Fund will only invest in variable amount master demand notes issued
by companies which at the date of investment have an outstanding debt issue
rated "Aaa" or "Aa" by Moody's or "AAA" or "AA" by S&P and which the applicable
Subadviser has determined present minimal risk of loss to the Fund. A Subadviser
will look generally at the financial strength of the issuing company as
"backing" for the note and not to any security interest or supplemental source
such as a bank letter of credit. A variable amount master demand note will be
valued each day as a Fund's net asset value is determined, which value will
generally be equal to the face value of the note plus accrued interest unless
the financial position of the issuer is such that its ability to repay the note
when due is in question.

     4.   Corporate Obligations. Corporate obligations include bonds and notes
issued by corporations to finance longer-term credit needs than those supported
by commercial paper. While such obligations generally have maturities of ten
years or more, the Money Market Fund will only purchase obligations which have
remaining maturities of thirteen months or less from the date of purchase and
which are rated "AA" or higher by S&P or "Aa" or higher by Moody's.

     5.   Repurchase Agreements. Repurchase agreements are arrangements
involving the purchase of obligations by a Fund and the simultaneous agreement
to resell the same obligations on demand or at a specified future date and at an
agreed upon price. The 

                                      -8-
<PAGE>
 
majority of repurchase transactions run from day to day and delivery pursuant to
the resale provision typically will occur within one to five business days of
the purchase. A repurchase agreement can be viewed as a loan made by a Fund to
the seller of the obligation with such obligation serving as collateral for the
seller's agreement to repay the amount borrowed with interest. Such transactions
afford an opportunity for a Fund to earn a return on cash which is only
temporarily available. Repurchase agreements entered into by the Fund will be
with banks, brokers or dealers. However, a Fund will enter into a repurchase
agreement with a broker or dealer only if the broker or dealer agrees to deposit
additional collateral should the value of the obligation purchased by the Fund
decrease below the resale price.

     The Trustees have adopted procedures that establish certain
creditworthiness, asset and collateralization requirements for the
counterparties to a Fund's repurchase agreements. These procedures limit the
counterparties to repurchase transactions to those financial institutions which
are members of the Federal Reserve System and/or a primary government securities
dealer reporting to the Federal Reserve Bank of New York's Market Reports
Division or a broker/dealer which meet certain creditworthiness criteria or
which report U.S. Government securities positions to the Federal Reserve Board.
However, the Trustees reserve the right to change the criteria used to select
such financial institutions and broker/dealers. The Trustees will regularly
monitor the use of repurchase agreements and the Subadvisers will, pursuant to
procedures adopted by the Trustees, continuously monitor the amount of
collateral held with respect to a repurchase transaction so that it equals or
exceeds the amount of the obligations.

     Should an issuer of a repurchase agreement fail to repurchase the
underlying obligation, the losses to the Fund, if any, would be the difference
between the repurchase price and the underlying obligation's market value.  A
Fund might also incur certain costs in liquidating the underlying obligation.
Moreover, if bankruptcy or other insolvency proceedings should be commenced with
respect to the seller, realization upon the underlying obligation by the Fund
might be delayed or limited.  Generally, repurchase agreements are of a short
duration, often less than one week but on occasion for longer periods.

     6.   Canadian and Provincial Government and Crown Agency Obligations.
Canadian Government obligations are debt securities issued or guaranteed as to
principal or interest by the Government of Canada pursuant to authority granted
by the Parliament of Canada and approved by the Governor in Council, where
necessary.  These securities include treasury bills, notes, bonds, debentures
and marketable Government of Canada loans.  Canadian Crown agency obligations
are debt securities issued or guaranteed by a Crown corporation, company or
agency ("Crown agencies") pursuant to authority granted by the Parliament of
Canada and approved by the Governor in Council, where necessary.  Certain Crown
agencies are by statute agents of Her Majesty in right of Canada, and their
obligations, when properly authorized, constitute direct obligations of the
Government of Canada.  Such obligations include, but are not limited to, those
issued or guaranteed by the Export Development Corporation, Farm Credit
Corporation, Federal Business Development Bank and Canada Post Corporation.  In
addition, certain Crown agencies which are not by law agents of Her Majesty may
issue obligations which by statute the Governor in Council may authorize the
Minister of Finance to guarantee on behalf of the Government of Canada.  Other
Crown agencies which are not by law agents of Her Majesty may issue or guarantee
obligations not entitled to be guaranteed by the Government of Canada.  No
assurance can be given that the Government of Canada will support the
obligations of Crown agencies which are not agents of Her Majesty, which it has
not guaranteed, since it is not obligated to do so by law.

     Provincial Government obligations are debt securities issued or guaranteed
as to principal or interest by the government of any province of Canada pursuant
to authority granted by the Legislature of any such province and approved by the
Lieutenant Governor in Council of any such province, where necessary.  These
securities include treasury bills, notes, bonds and debentures.  Provincial
Crown agency obligations are debt securities issued or guaranteed by a
provincial Crown corporation, company or agency ("provincial Crown agencies")
pursuant to authority granted by a provincial Legislature and approved by the
Lieutenant Governor in Council of such province, where necessary.  Certain
provincial Crown agencies are by statute agents of Her Majesty in right of a
particular province of Canada, and their obligations, when properly authorized,
constitute direct obligations of such province.  Other provincial Crown agencies
which are not by law agents of Her Majesty in right of a particular province of
Canada may issue obligations which by statute the Lieutenant Governor in Council
of such province may guarantee, or may authorize the Treasurer thereof to
guarantee, on behalf of the government of such province.  Finally, other
provincial Crown agencies which are not by law agencies of Her Majesty may issue
or guarantee obligations not entitled to be guaranteed by a provincial
government.  No assurance can be given that the government of any province of
Canada will support the obligations of provincial Crown agencies which are not
agents of Her Majesty, which it has not guaranteed, as it is not obligated to do
so by law.  Provincial Crown agency obligations described above include, but are
not limited to, those issued or guaranteed by a provincial railway corporation,
a provincial hydroelectric or power commission or authority, a provincial
municipal financing corporation or agency and a provincial telephone commission
or authority.

     Any Canadian obligation acquired by the Money Market Fund will be
denominated in U.S. dollars.

PREFERRED STOCK AND CONVERTIBLE SECURITIES

     Preferred stock is a class of capital stock that pays dividends at a
specified rate and that has preference over common stock in the payment of
dividends and the liquidation of assets.  Preferred stock does not ordinarily
carry voting rights.  Convertible securities are securities (usually preferred
shares or bonds) that are exchangeable for a set number of another form of
securities (usually common stock) at a prestated price.  The convertible feature
is usually designed as a sweetener to enhance the marketability of the security.

                                      -9-
<PAGE>
 
MORTGAGE SECURITIES

     Mortgage securities differ from conventional bonds in that principal is
paid over the life of the securities rather than at maturity. As a result, a
Fund receives monthly scheduled payments of principal and interest, and may
receive unscheduled principal payments representing prepayments on the
underlying mortgages. When a Fund reinvests the payments and any unscheduled
prepayments of principal it receives, it may receive a rate of interest which is
higher or lower than the rate on the existing mortgage securities. For this
reason, mortgage securities may be less effective than other types of debt
securities as a means of locking in long-term interest rates.

     In addition, because the underlying mortgage loans and assets may be
prepaid at any time, if a Fund purchases mortgage securities at a premium, a
prepayment rate that is faster than expected will reduce yield to maturity,
while a prepayment rate that is slower than expected will have the opposite
effect of increasing yield to maturity. Conversely, if a Fund purchases these
securities at a discount, faster than expected prepayments will increase, while
slower than expected payments will reduce, yield to maturity.

     Adjustable rate mortgage securities are similar to the mortgage securities
discussed above, except that unlike fixed rate mortgage securities, adjustable
rate mortgage securities are collateralized by or represent interests in
mortgage loans with variable rates of interest. These variable rates of interest
reset periodically to align themselves with market rates. Most adjustable rate
mortgage securities provide for an initial mortgage rate that is in effect for a
fixed period, typically ranging from three to twelve months. Thereafter, the
mortgage interest rate will reset periodically in accordance with movements in a
specified published interest rate index. The amount of interest due to an
adjustable rate mortgage holder is determined in accordance with movements in a
specified published interest rate index by adding a pre-determined increment or
"margin" to the specified interest rate index. Many adjustable rate mortgage
securities reset their interest rates based on changes in the one-year, three-
year and five-year constant maturity Treasury rates, the three-month or six-
month Treasury Bill rate, the 11th District Federal Home Loan Bank Cost of
Funds, the National Median Cost of Funds, the one-month, three-month, six-month
or one-year London Interbank Offered Rate ("LIBOR") and other market rates.

     A Fund will not benefit from increases in interest rates to the extent that
interest rates rise to the point where they cause the current coupon of
adjustable rate mortgages held as investments to exceed any maximum allowable
annual or lifetime reset limits (or "cap rates") for a particular mortgage. In
this event, the value of the mortgage securities in a Fund would likely
decrease. Also, the Fund's net asset value could vary to the extent that current
yields on adjustable rate mortgage securities are different than market yields
during interim periods between coupon reset dates. During periods of declining
interest rates, income to a Fund derived from adjustable rate mortgages which
remain in a mortgage pool will decrease in contrast to the income on fixed rate
mortgages, which will remain constant. Adjustable rate mortgages also have less
potential for appreciation in value as interest rates decline than do fixed rate
investments.

     PRIVATELY-ISSUED MORTGAGE SECURITIES. Privately-issued pass through
securities provide for the monthly principal and interest payments made by
individual borrowers to pass through to investors on a corporate basis, and in
privately-issued collateralized mortgage obligations, as further described
below. Privately-issued mortgage securities are issued by private originators
of, or investors in, mortgage loans, including mortgage bankers, commercial
banks, investment banks, savings and loan associations and special purpose
subsidiaries of the foregoing. Since privately-issued mortgage certificates are
not guaranteed by an entity having the credit status of GNMA or FHLMC, such
securities generally are structured with one or more types of credit
enhancement. For a description of the types of credit enhancements that may
accompany privately-issued mortgage securities, see "Asset-Backed Securities--
Types of Credit Support" below. A Fund will not limit its investments to asset-
backed securities with credit enhancements.

     COLLATERALIZED MORTGAGE OBLIGATIONS ("CMOS"). CMOs generally are bonds or
certificates issued in multiple classes that are collateralized by or represent
an interest in mortgages. CMOs may be issued by single-purpose, stand-alone
finance subsidiaries or trusts of financial institutions, government agencies,
investment banks or other similar institutions. Each class of CMOs, often
referred to as a "tranche", may be issued with a specific fixed coupon rate
(which may be zero) or a floating coupon rate, and has a stated maturity or
final distribution date. Principal prepayments on the underlying mortgages may
cause the CMOs to be retired substantially earlier than their stated maturities
or final distribution dates. Interest is paid or accrued on CMOs on a monthly,
quarterly or semiannual basis. The principal of and interest on the underlying
mortgages may be allocated among the several classes of a series of a CMO in
many ways. The general goal sought to be achieved in allocating cash flows on
the underlying mortgages to the various classes of a series of CMOs is to create
tranches on which the expected cash flows have a higher degree of predictability
than the underlying mortgages. As a general matter, the more predictable the
cash flow is on a CMO tranche, the lower the anticipated yield will be on that
tranche at the time of issuance. As part of the process of creating more
predictable cash flows on most of the tranches in a series of CMOs, one or more
tranches generally must be created that absorb most of the volatility in the
cash flows on the underlying mortgages. The yields on these tranches are
relatively higher than on tranches with more predictable cash flows. Because of
the uncertainty of the cash flows on these tranches, and the sensitivity thereof
to changes in prepayment rates on the underlying mortgages, the market prices of
and yield on these tranches tend to be highly volatile.

                                      -10-
<PAGE>
 
     CMOs purchased may be:

     (1)  collateralized by pools of mortgages in which each mortgage is
guaranteed as to payment of principal and interest by an agency or
instrumentality of the U.S. Government;

     (2)  collateralized by pools of mortgages in which payment of principal and
interest is guaranteed by the issuer and the guarantee is collateralized by U.S.
Government securities; or

     (3)  securities for which the proceeds of the issuance are invested in
mortgage securities and payment of the principal and interest is supported by
the credit of an agency or instrumentality of the U.S. Government.

     STRIPS. In addition to the U.S. Government securities discussed above,
certain Funds may invest in separately traded interest components of securities
issued or guaranteed by the U.S. Treasury. The interest components of selected
securities are traded independently under the Separate Trading of Registered
Interest and Principal of Securities program ("STRIPS"). Under the STRIPS
program, the interest components are individually numbered and separately issued
by the U.S. Treasury at the request of depository financial institutions, which
then trade the component parts independently.

     STRIPPED MORTGAGE SECURITIES. Stripped mortgage securities are derivative
multiclass mortgage securities. Stripped mortgage securities may be issued by
agencies or instrumentalities of the U.S. Government, or by private issuers,
including savings and loan associations, mortgage banks, commercial banks,
investment banks and special purpose subsidiaries of the foregoing. Stripped
mortgage securities have greater volatility than other types of mortgage
securities in which a Fund invests. Although stripped mortgage securities are
purchased and sold by institutional investors through several investment banking
firms acting as brokers or dealers, the market for such securities has not yet
been fully developed. Accordingly, stripped mortgage securities are generally
illiquid and to such extent, together with any other illiquid investments, will
not exceed 10% (or 15% with respect to the Emerging Growth Fund and the Tax-
Sensitive Equity Fund) of a Fund's net assets.

     Stripped mortgage securities are usually structured with two classes that
receive different proportions of the interest and principal distributions on a
pool of mortgage assets. A common type of stripped mortgage security will have
one class receiving some of the interest and most of the principal from the
mortgage assets, while the other class will receive most of the interest and the
remainder of the principal. In the most extreme case, one class will receive all
of the interest (the interest-only or "IO" class), while the other class will
receive all of the principal (the principal-only or "PO" class). The yield to
maturity on an IO class is extremely sensitive not only to changes in prevailing
interest rates but also the rate of principal payments (including prepayments)
on the related underlying mortgage assets, and a rapid rate of principal
payments may have a material adverse effect on a Fund's yield to maturity. If
the underlying mortgage assets experience greater than anticipated prepayments
of principal, a Fund may fail to fully recoup its initial investment in these
securities even if the securities have received the highest rating by a
nationally recognized statistical rating organization.

     As interest rates rise and fall, the value of IOs tends to move in the same
direction as interest rates. The value of the other mortgage securities
described in this Statement of Additional Information, like other debt
instruments, will tend to move in the opposite direction of interest rates.
Accordingly, the Fund believes that investing in IOs, in conjunction with the
other mortgage securities described herein, will contribute to a Fund's
relatively stable net asset value.

     In addition to the stripped mortgage securities described above, the
Strategic Income may invest in similar securities such as Super POs and Levered
IOs which are more volatile than POs or IOs. Risks associated with instruments
such as Super POs are similar in nature to those risks related to investments in
POs. Risks connected with Levered IOs and IOettes are similar in nature to those
associated with IOs. The Strategic Income Fund may also invest in other similar
instruments developed in the future that are deemed consistent with the
investment objective, policies and restrictions of the Fund.

     Under the Internal Revenue Code of 1986, as amended (the "Code"), POs may
generate taxable income from the current accrual of original issue discount,
without a corresponding distribution of cash to a Fund. See "Taxes -- Pay-in-
kind Bonds, Zero Coupon Bonds and Discount Obligations."

     INVERSE FLOATERS.  The Strategic Income and National Municipal Bond Funds
may invest in inverse floaters, which are also derivative mortgage securities.
Inverse floaters may be issued by agencies or instrumentalities of the U.S.
Government, or by private issuers, including savings and loan associations,
mortgage banks, commercial banks, investment banks and special purpose
subsidiaries of the foregoing. Inverse floaters have greater volatility than
other types of mortgage securities in which a Fund invests (with the exception
of stripped mortgage securities). Although inverse floaters are purchased and
sold by institutional investors through several investment banking firms acting
as brokers or dealers, the market for such securities has not yet been fully
developed. Accordingly, inverse floaters are generally illiquid and to such
extent, together with any other illiquid investments, will not exceed 10% of the
Fund's net assets.

                                      -11-
<PAGE>
 
     Inverse floaters are structured as a class of security that receives
distributions on a pool of mortgage assets and whose yields move in the opposite
direction of short-term interest rates and at an accelerated rate.  Such
securities have the effect of providing a degree of investment leverage since
they will generally increase or decrease in value in response to changes in
market interest rates at a rate which is a multiple (typically two) of the rate
at which fixed-rate long-term debt obligations increase or decrease in response
to such changes.  As a result, the market values of such securities will
generally be more volatile than the market value of fixed-rate obligations.

ASSET-BACKED SECURITIES

     The securitization techniques used to develop mortgage securities are also
being applied to a broad range of other assets. Through the use of trusts and
special purpose corporations, automobile and credit card receivables are being
securitized in pass-through structures similar to mortgage pass-through
structures or in a pay-through structure similar to the CMO structure. Generally
the issuers of asset-backed bonds, notes or pass-through certificates are
special purpose entities and do not have any significant assets other than the
receivables securing such obligations. In general, the collateral supporting
asset-backed securities is of a shorter maturity than mortgage loans. As a
result, investment in these securities should result in greater price stability
for a Fund's shares. Instruments backed by pools of receivables are similar to
mortgage-backed securities in that they are subject to unscheduled prepayments
of principal prior to maturity. When the obligations are prepaid, a Fund must
reinvest the prepaid amounts in securities the yields of which reflect interest
rates prevailing at the time. Therefore, a Fund's ability to maintain a
portfolio which includes high-yielding asset-backed securities will be adversely
affected to the extent that prepayments of principal must be reinvested in
securities which have lower yields than the prepaid obligations. Moreover,
prepayments of securities purchased at a premium could result in a realized
loss. A Fund will only invest in asset-backed securities rated, at the time of
purchase, "AA" or better by S&P or "Aa" or better by Moody's or which, in the
opinion of the applicable Subadviser, are of comparable quality.

     As with mortgage securities, asset-backed securities are often backed by a
pool of assets representing the obligations of a number of different parties and
use similar credit enhancement techniques. For a description of the types of
credit enhancement that may accompany privately-issued mortgage securities, see
"Types of Credit Support" below. A Fund will not limit its investments to asset-
backed securities with credit enhancements. Although asset-backed securities are
not generally traded on a national securities exchange, such securities are
widely traded by brokers and dealers, and to such extent will not be considered
illiquid securities.

     TYPES OF CREDIT SUPPORT. Mortgage securities and asset-backed securities
are often backed by a pool of assets representing the obligations of a number of
different parties. To lessen the effect of failure by obligors on underlying
assets to make payments, such securities may contain elements of credit support.
Such credit support falls into two categories: (i) liquidity protection and (ii)
protection against losses resulting from ultimate default by an obligor on the
underlying assets. Liquidity protection refers to the provision of advances,
generally by the entity administering the pool of assets, to ensure that the
pass-through of payments due on the underlying pool occurs in a timely fashion.
Protection against losses resulting from ultimate default enhances the
likelihood of ultimate payment of the obligations on at least a portion of the
assets in the pool. Such protection may be provided through guarantees,
insurance policies or letters of credit obtained by the issuer or sponsor from
third parties, through various means of structuring the transaction or through a
combination of such approaches. The Funds will not pay any additional fees for
such credit support, although the existence of credit support may increase the
price of a security.

     The ratings of mortgage securities and asset-backed securities for which
third-party credit enhancement provides liquidity protection or protection
against losses from default are generally dependent upon the continued
creditworthiness of the provider of the credit enhancement. The ratings of such
securities could be subject to reduction in the event of deterioration in the
creditworthiness of the credit enhancement provider even in cases where the
delinquency and loss experience on the underlying pool of assets is better than
expected.

     Examples of credit support arising out of the structure of the transaction
include "senior-subordinated securities" (multiple class securities with one or
more classes subordinate to other classes as to the payment of principal thereof
and interest thereon, with the result that defaults on the underlying assets are
borne first by the holders of the subordinated class), creation of "reserve
funds" (where cash or investments sometimes funded from a portion of the
payments on the underlying assets are held in reserve against future losses) and
"over-collateralization" (where the scheduled payments on, or the principal
amount of, the underlying assets exceed those required to make payment of the
securities and pay any servicing or other fees). The degree of credit support
provided for each issue is generally based on historical information with
respect to the level of credit risk associated with the underlying assets.
Delinquency or loss in excess of that which is anticipated could adversely
affect the return on an investment in such security.

                                      -12-

ZERO COUPON SECURITIES AND PAY-IN-KIND BONDS

     Zero coupon securities and pay-in-kind bonds involve special risk
considerations. Zero coupon securities are debt securities that do not provide
for the payment of cash income but are sold at substantial discounts from their
value at maturity. When a zero coupon security is held to maturity, its entire
return, which consists of the amortization of discount, comes from the
difference between its purchase price and its maturity value. This difference is
known at the time of purchase, so that investors holding zero coupon securities
until maturity know at the time of their investment what the return on their
investment will be. Certain zero coupon securities also are sold at substantial
discounts from their maturity value and provide for the commencement of regular
interest payments at a deferred date. The Funds also may purchase pay-in-kind
bonds. Pay-in-kind bonds are bonds that pay all or a portion of their interest
in the form of additional debt or equity securities. The U.S. Government
Securities Fund will not invest in zero coupon securities having maturities of
greater than ten years.

     Zero coupon securities and pay-in-kind bonds tend to be subject to greater
price fluctuations in response to changes in interest rates than are ordinary
interest-paying debt securities with similar maturities. The value of zero
coupon securities appreciates more during periods of declining interest rates
and depreciates more during periods of rising interest rates.

     Zero coupon securities and pay-in-kind bonds may be issued by a wide
variety of corporate and governmental issuers.  Although zero coupon securities
and pay-in-kind bonds are generally not traded on a national securities
exchange, such securities are widely traded by brokers and dealers and, to such
extent, will not be considered illiquid for the purposes of the investment
restriction under "Investment Restrictions" below.

     Current federal income tax law requires the holder of a zero coupon
security or certain pay-in-kind bonds to accrue income with respect to these
securities prior to the receipt of cash payments.  To maintain its qualification
as a regulated investment company and avoid liability for federal income and
excise taxes, a Fund may be required to distribute income accrued with respect
to these securities and may have to dispose of portfolio securities under
disadvantageous circumstances in order to generate cash to satisfy these
distribution requirements.

HIGH YIELD/HIGH RISK DOMESTIC CORPORATE DEBT SECURITIES

     High yield U.S. corporate debt securities include bonds, debentures, notes
and commercial paper and will generally be unsecured. Most of these debt
securities will bear interest at fixed rates. However, a Fund may also invest in
debt securities with variable rates of interest or which involve equity
features, such as contingent interest or participations based on revenues, sales
or profits (i.e., interest or other payments, often in addition to a fixed rate
of return, that are based on the borrower's attainment of specified levels of
revenues, sales or profits and thus enable the holder of the security to share
in the potential success of the venture).

     Because the Strategic Income and Investment Quality Bond Funds will invest
primarily in fixed-income securities, the net asset value of each Fund's shares
can be expected to change as general levels of interest rates fluctuate,
although the market values of securities rated below investment grade and
comparable unrated securities tend to react less to fluctuations in interest
rate levels than do those of higher-rated securities. Except to the extent that
values are affected independently by other factors such as developments relating
to a specific issuer, when interest rates decline, the value of a fixed-income
Fund can generally be expected to rise. Conversely, when interest rates rise,
the value of a fixed-income Fund can generally be expected to decline.

     The secondary markets for high yield corporate and sovereign debt
securities are not as liquid as the secondary markets for higher rated
securities. The secondary markets for high yield debt securities are
concentrated in relatively few market makers and participants in the market are
mostly institutional investors, including insurance companies, banks, other
financial institutions and mutual funds. In addition, the trading volume for
high yield debt securities is generally lower than that for higher-rated
securities and the secondary markets could contract under adverse market or
economic conditions independent of any specific adverse changes in the condition
of a particular issuer. These factors may have an adverse effect on a Fund's
ability to dispose of particular Fund investments and may limit the ability of
those Funds to obtain accurate market quotations for purposes of valuing
securities and calculating net asset value. If a Fund is not able to obtain
precise or accurate market quotations for a particular security, it will become
more difficult for the Trustees to value such Fund's investment Fund and the
Fund's Trustees may have to use a greater degree of judgment in making such
valuations. Less liquid secondary markets may also affect a Fund's ability to
sell securities at their fair value. In addition, each Fund may invest up to 10%
of its net assets, measured at the time of investment, in illiquid securities,
which may be more difficult to value and to sell at fair value. If the secondary
markets for high yield debt securities are affected by adverse economic
conditions, the proportion of a Fund's assets invested in illiquid securities
may increase.

     While the market values of securities rated below investment grade and
comparable unrated securities tend to react less to fluctuations in interest
rate levels than do those of higher-rated securities, the market values of
certain of these securities also tend to be more sensitive to individual
corporate developments and changes in economic conditions than higher-rated
securities. In addition, such securities generally present a higher degree of
credit risk. Issuers of these securities are often highly leveraged and may not
have more traditional methods of financing available to them, so that their
ability to service their debt obligations during an economic downturn or during
sustained periods of rising interest rates may be impaired. The risk of loss due
to default by such issuers is 

                                      -13-
<PAGE>
 
significantly greater than with investment grade securities because such
securities generally are unsecured and frequently are subordinated to the prior
payment of senior indebtedness.

HIGH YIELD/HIGH RISK FOREIGN SOVEREIGN DEBT SECURITIES

     The Strategic Income, High Yield and Investment Quality Bond Funds expect
that a significant portion of their emerging market governmental debt
obligations will consist of "Brady Bonds." In addition, the International Small
Cap, and Balanced Funds may also invest in Brady Bonds. Brady Bonds are debt
securities, generally denominated in U.S. dollars, issued under the framework of
the "Brady Plan," an initiative announced by former U.S. Treasury Secretary
Nicholas F. Brady in 1989 as a mechanism for debtor nations to restructure their
outstanding external commercial bank indebtedness. The Brady Plan framework, as
it has developed, contemplates the exchange of external commercial bank debt for
newly issued bonds (Brady Bonds). Brady Bonds may also be issued in respect of
new money being advanced by existing lenders in connection with the debt
restructuring. Investors should recognize that Brady Bonds have been issued only
recently, and accordingly do not have a long payment history. Brady Bonds issued
to date generally have maturities of between 15 and 30 years from the date of
issuance and have traded at a deep discount from their face value. The Funds may
invest in Brady Bonds of emerging market countries that have been issued to
date, as well as those which may be issued in the future. In addition to Brady
Bonds, the Funds may invest in emerging market governmental obligations issued
as a result of debt restructuring agreements outside of the scope of the Brady
Plan. A substantial portion of the Brady Bonds and other sovereign debt
securities in which the Funds invest are likely to be acquired at a discount,
which involves certain considerations discussed below under "TAXES -- Pay-in-
kind Bonds, Zero Coupon Bonds and Discount Obligations."

     Agreements implemented under the Brady Plan to date are designed to achieve
debt and debt-service reduction through specific options negotiated by a debtor
nation with its creditors. As a result, the financial packages offered by each
country differ. The types of options have included the exchange of outstanding
commercial bank debt for bonds issued at 100% of face value of such debt which
carry a below-market stated rate of interest (generally known as par bonds),
bonds issued at a discount from the face value of such debt (generally known as
discount bonds), bonds bearing an interest rate which increases over time and
bonds issued in exchange for the advancement of new money by existing lenders.
Discount bonds issued to date under the framework of the Brady Plan have
generally borne interest computed semiannually at a rate equal to 13/16 of one
percent above the then current six month LIBOR rate. Regardless of the stated
face amount and stated interest rate of the various types of Brady Bonds, the
Funds will purchase Brady Bonds in secondary markets, as described below, in
which the price and yield to the investor reflect market conditions at the time
of purchase. Brady Bonds issued to date have traded at a deep discount from
their face value. Certain sovereign bonds are entitled to "value recovery
payments" in certain circumstances, which in effect constitute supplemental
interest payments but generally are not collateralized. Certain Brady Bonds have
been collateralized as to principal due at maturity (typically 15 to 30 years
from the date of issuance) by U.S. Treasury zero coupon bonds with a maturity
equal to the final maturity of such Brady Bonds, although the collateral is not
available to investors until the final maturity of the Brady Bonds. Collateral
purchases are financed by the International Monetary Fund (the "IMF"), the World
Bank and the debtor nations' reserves. In addition, interest payments on certain
types of Brady Bonds may be collateralized by cash or high-grade securities in
amounts that typically represent between 12 and 18 months of interest accruals
on these instruments with the balance of the interest accruals being
uncollateralized. The Funds may purchase Brady Bonds with no or limited
collateralization, and will be relying for payment of interest and (except in
the case of principal collateralized Brady Bonds) principal primarily on the
willingness and ability of the foreign government to make payment in accordance
with the terms of the Brady Bonds. Brady Bonds issued to date are purchased and
sold in secondary markets through U.S. securities dealers and other financial
institutions and are generally maintained through European transnational
securities depositories.

FOREIGN SOVEREIGN DEBT SECURITIES

     Investing in foreign sovereign debt securities will expose a Fund to the
direct or indirect consequences of political, social or economic changes in the
developing and emerging countries that issue the securities. The ability and
willingness of sovereign obligors in developing and emerging countries or the
governmental authorities that control repayment of their external debt to pay
principal and interest on such debt when due may depend on general economic and
political conditions within the relevant country. Countries such as those in
which the Funds may invest have historically experienced, and may continue to
experience, high rates of inflation, high interest rates, exchange rate trade
difficulties and extreme poverty and unemployment. Many of these countries are
also characterized by political uncertainty or instability. Additional factors
which may influence the ability or willingness to service debt include, but are
not limited to, a country's cash flow situation, the availability of sufficient
foreign exchange on the date a payment is due, the relative size of its debt
service burden to the economy as a whole, and its government's policy towards
the International Monetary Fund, the World Bank and other international
agencies.

     The ability of a foreign sovereign obligor to make timely payments on its
external debt obligations will also be strongly influenced by the obligor's
balance of payments, including export performance, its access to international
credits and investments, fluctuations in interest rates and the extent of its
foreign reserves. A country whose exports are concentrated in a few commodities
or whose economy depends on certain strategic imports could be vulnerable to
fluctuations in international prices of these commodities or imports. To the
extent that a country receives payment for its exports in currencies other than
dollars, its ability to make debt payments denominated in dollars could be
adversely affected. If a foreign sovereign obligor cannot generate sufficient
earnings from foreign trade to service its external debt, it may need to depend
on continuing loans and aid from foreign governments, commercial 

                                      -14-
<PAGE>
 
banks and multilateral organizations, and inflows of foreign investment. The
commitment on the part of these foreign governments, multilateral organizations
and others to make such disbursements may be conditioned on the government's
implementation of economic reforms and/or economic performance and the timely
service of its obligations. Failure to implement such reforms, achieve such
levels of economic performance or repay principal or interest when due may
result in the cancellation of such third parties' commitments to lend funds,
which may further impair the obligor's ability or willingness to timely service
its debts. The cost of servicing external debt will also generally be adversely
affected by rising international interest rates, because many external debt
obligations bear interest at rates which are adjusted based upon international
interest rates. The ability to service external debt will also depend on the
level of the relevant government's international currency reserves and its
access to foreign exchange. Currency devaluations may affect the ability of a
sovereign obligor to obtain sufficient foreign exchange to service its external
debt.

     As a result of the foregoing, a governmental obligor may default on its
obligations. If such an event occurs, a Fund may have limited legal recourse
against the issuer and/or guarantor. Remedies must, in some cases, be pursued in
the courts of the defaulting party itself, and the ability of the holder of
foreign sovereign debt securities to obtain recourse may be subject to the
political climate in the relevant country. In addition, no assurance can be
given that the holders of commercial bank debt will not contest payments to the
holders of other foreign sovereign debt obligations in the event of default
under their commercial bank loan agreements.

     Sovereign obligors in developing and emerging countries are among the
world's largest debtors to commercial banks, other governments, international
financial organizations and other financial institutions. These obligors have in
the past experienced substantial difficulties in servicing their external debt
obligations, which led to defaults on certain obligations and the restructuring
of certain indebtedness. Restructuring arrangements have included, among other
things, reducing and rescheduling interest and principal payments by negotiating
new or amended credit agreements or converting outstanding principal and unpaid
interest to Brady Bonds, and obtaining new credit to finance interest payments.
Holders of certain foreign sovereign debt securities may be requested to
participate in the restructuring of such obligations and to extend further loans
to their issuers. There can be no assurance that the Brady Bonds and other
foreign sovereign debt securities in which the Funds may invest will not be
subject to similar restructuring arrangements or to requests for new credit
which may adversely affect a Fund's holdings. Furthermore, certain participants
in the secondary market for such debt may be directly involved in negotiating
the terms of these arrangements and may therefore have access to information not
available to other market participants.

     In addition to high yield foreign sovereign debt securities, many of the
Funds may also invest in investment grade foreign securities.

FOREIGN SECURITIES

     Securities of foreign issuers include obligations of foreign branches of
U.S. banks and of foreign banks, common and preferred stocks, debt securities
issued by foreign governments, corporations and supranational organizations, and
American Depository Receipts, European Depository Receipts and Global Depository
Receipts ("ADRs", "EDRs" and "GDRs", respectively). ADRs are U.S. dollar-
denominated securities backed by foreign securities deposited in a U.S.
securities depository. ADRs are created for trading in the U.S. markets. The
value of an ADR will fluctuate with the value of the underlying security,
reflect any changes in exchange rates and otherwise involve risks associated
with investing in foreign securities. ADRs in which the Funds may invest may be
sponsored or unsponsored. There may be less information available about foreign
issuers of unsponsored ADRs. EDRs and GDRs are receipts evidencing an
arrangement with a non-U.S. bank similar to that for ADRs and are designed for
use in non-U.S. securities markets. EDRs and GDRs are not necessarily quoted in
the same currency as the underlying security.

     Foreign markets, especially emerging markets, may have different clearance
and settlement procedures, and in certain markets there have been times when
settlements have been unable to keep pace with the volume of securities
transactions, making it difficult to conduct such transactions. Delays in
settlement could result in temporary periods when a portion of the assets of a
Fund is uninvested and no return is earned thereon. The inability of a Fund to
make intended security purchases due to settlement could cause the Fund to miss
attractive investment opportunities. Inability to dispose of Fund securities due
to settlement problems could result in losses to a Fund due to subsequent
declines in values of the Fund securities or, if the Fund has entered into a
contract to sell the security, possible liability to the purchaser. Certain
foreign markets, especially emerging markets, may require governmental approval
for the repatriation of investment income, capital or the proceeds of sales of
securities by foreign investors. A Fund could be adversely affected by delays
in, or a refusal to grant, any required governmental approval for repatriation
of capital, as well as by the application to the Fund of any restrictions on
investments.

WARRANTS

     Subject to certain restrictions, each of the Funds except the National
Municipal Bond and Money Market Funds may purchase warrants, including warrants
traded independently of the underlying securities. Warrants are rights to
purchase securities at specific prices valid for a specific period of time.
Their prices do not necessarily move parallel to the prices of the underlying
securities, and warrant holders receive no dividends and have no voting rights
or rights with respect to the assets of an issuer. Warrants cease to have value
if not exercised prior to the expiration date. It is a non-fundamental
investment restriction of each Fund (except the Emerging Growth Fund and the 
Tax-Sensitive Equity Fund) not to purchase warrants if as a result that Fund
would then 

                                      -15-
<PAGE>
 
have more than 10% of its total net assets invested in warrants, or if more than
5% of the value of the Fund's total net assets would be invested in warrants
which are not listed on a recognized United States or foreign stock exchange,
except for warrants included in units or attached to other securities.

WHEN-ISSUED SECURITIES ("FORWARD COMMITMENTS")

     In order to help ensure the availability of suitable securities, each of
the Funds may purchase debt securities on a "when-issued" or on a "forward
delivery" basis, which means that the obligations will be delivered to the Fund
at a future date, which may be a month or more after the date of commitment
(referred to as "forward commitments"). It is expected that, under normal
circumstances, a Fund purchasing securities on a when-issued or forward delivery
basis will take delivery of the securities, but the Fund may sell the securities
before the settlement date, if such action is deemed advisable. In general, a
Fund does not pay for the securities or start earning interest on them until the
purchase of the obligation is scheduled to be settled, but it does, in the
meantime, record the transaction and reflect the value each day of the
securities in determining its net asset value. At the time delivery is made, the
value of when-issued or forward delivery securities may be more or less than the
transaction price, and the yields then available in the market may be higher
than those obtained in the transaction. While awaiting delivery of the
obligations purchased on such bases, a Fund will establish a segregated account
consisting of cash or liquid high quality debt securities equal to the amount of
the commitments to purchase when-issued or forward delivery securities. The
availability of liquid assets for this purpose and the effect of asset
segregation on a Fund's ability to meet its current obligations, to honor
requests for redemption and to have its investment Fund managed properly will
limit the extent to which the Fund may purchase when-issued or forward delivery
securities. Except as may be imposed by these factors, there is no limit on the
percentage of a Fund's total assets that may be committed to such transactions.

ILLIQUID SECURITIES

     Each of the Funds (except the Tax-Sensitive Equity Fund and the Emerging
Growth Fund, which may not invest more than 15%) is precluded from investing in
excess of 10% of its net assets in securities that are not readily marketable.
Investment in illiquid securities involves the risk that, because of the lack of
consistent market demand for such securities, a Fund may be forced to sell them
at a discount from the last offer price. Excluded from the 10% limitation (or
15% with regard to the Tax-Sensitive Equity Fund and the Emerging Growth Fund)
are securities that are restricted as to resale but for which a ready market is
available pursuant to exemption provided by Rule 144A adopted under the
Securities Act of 1933, as amended (the "1933 Act") or other exemptions from
the registration requirements of the 1933 Act. Whether securities sold pursuant
to Rule 144A are readily marketable for purposes of the Fund's investment
restriction is a determination to be made by the Subadvisers, subject to the
Trustees' oversight and for which the Trustees are ultimately responsible. The
Subadvisers will also monitor the liquidity of Rule 144A securities held by the
Funds for which they are responsible. To the extent Rule 144A securities held by
a Fund should become illiquid because of a lack of interest on the part of
qualified institutional investors, the overall liquidity of the Fund could be
adversely affected. In addition, the Money Market Fund may invest in commercial
paper issued in reliance on the exemption from registration afforded by Section
4(2) of the 1933 Act. Section 4(2) commercial paper is restricted as to the
disposition under federal securities law, and is generally sold to institutional
investors, such as the Fund, who agree that they are purchasing the paper for
investment purposes and not with a view to public distribution. Any resale by
the purchaser must be made in an exempt transaction. Section 4(2) commercial
paper is normally resold to other institutional investors like the Money Market
Fund through or with the assistance of the issuer or investment dealers who make
a market in Section 4(2) commercial paper, thus providing liquidity. The Money
Market Fund's subadviser believes that Section 4(2) commercial paper meets its
criteria for liquidity and is quite liquid. The Money Market Fund intends,
therefore, to treat Section 4(2) commercial paper as liquid and not subject to
the investment limitation applicable to illiquid securities. The Money Market
Fund's subadviser will monitor the liquidity of Section 4(2) commercial paper
held by the Money Market Fund, subject to the Trustees' oversight and for which
the Trustees are ultimately responsible.

REPURCHASE AGREEMENTS AND REVERSE REPURCHASE AGREEMENTS

     Each of the Funds may enter into repurchase agreements and reverse
repurchase agreements. Repurchase agreements involve the acquisition by a Fund
of debt securities subject to an agreement to resell them at an agreed-upon
price. Under a repurchase agreement, at the time the Fund acquires a security,
it agrees to resell it to the original seller (a financial institution or
broker/dealer which meets the guidelines established by the Trustees) and must
deliver the security (and/or securities that may be added to or substituted for
it under the repurchase agreement) to the original seller on an agreed-upon date
in the future. The repurchase price is in excess of the purchase price. The
arrangement is in economic effect a loan collateralized by securities.

     A Fund's risk in a repurchase transaction is limited to the ability of the
seller to pay the agreed-upon sum on the delivery date. In the event of
bankruptcy or other default by the seller, there may be possible delays and
expenses in liquidating the instrument purchased, decline in its value and loss
of interest. Securities subject to repurchase agreements will be valued every
business day and additional collateral will be requested if necessary so that
the value of the collateral is at least equal to the value of the repurchase
obligation, including the interest accrued thereon.

                                      -16-
<PAGE>
 
     Each Fund of the Fund may enter into "reverse" repurchase agreements.
Under a reverse repurchase agreement, a Fund may sell a debt security and agree
to repurchase it at an agreed upon time and at an agreed upon price. The Fund
retains record ownership of the security and the right to receive interest and
principal payments thereon. At an agreed upon future date, the Fund repurchases
the security by remitting the proceeds previously received, plus interest. The
difference between the amount the Fund receives for the security and the amount
it pays on repurchase is deemed to be payment of interest. The Fund will
maintain in a segregated custodial account cash, Treasury bills or other U.S.
Government securities having an aggregate value equal to the amount of such
commitment to repurchase including accrued interest, until payment is made. In
certain types of agreements, there is no agreed-upon repurchase date and
interest payments are calculated daily, often based on the prevailing overnight
repurchase rate. While a reverse repurchase agreement may be considered a form
of leveraging and may, therefore, increase fluctuations in a Fund's net asset
value per share, each Fund will cover the transaction as described above.

MORTGAGE DOLLAR ROLLS

     Each of the Funds (except the Money Market Fund) may enter into mortgage
dollar rolls. Under a mortgage dollar roll, a Fund sells mortgage-backed
securities for delivery in the future (generally within 30 days) and
simultaneously contracts to repurchase substantially similar (same type, coupon
and maturity) securities on a specified future date. During the roll period, the
Fund forgoes principal and interest paid on the mortgage-backed securities. A
Fund is compensated by the difference between the current sale price and the
lower forward price for the future purchase (often referred to as the "drop")
as well as by the interest earned on the cash proceeds of the initial sale. A
Fund may also be compensated by receipt of a commitment fee. A Fund may only
enter into covered rolls. A "covered roll" is a specific type of dollar roll
for which there is an offsetting cash or cash equivalent security position which
matures on or before the forward settlement date of the dollar roll transaction.
Dollar roll transactions involve the risk that the market value of the
securities sold by the Fund may decline below the repurchase price of those
securities. While a mortgage dollar roll may be considered a form of leveraging
and may, therefore, increase fluctuations in a Fund's net asset value per share,
each Fund will cover the transaction as described above.

HYBRID INSTRUMENTS

     Hybrid instruments (a type of potentially high-risk derivative) have been
developed and combine the elements of futures contracts or options with those of
debt, preferred equity or a depository instrument (hereinafter "Hybrid
Instruments"). Generally, a Hybrid Instrument will be a debt security, preferred
stock, depository share, trust certificate, certificate of deposit or other
evidence of indebtedness on which a portion of or all interest payments, and/or
the principal or stated amount payable at maturity, redemption or retirement, is
determined by reference to prices, changes in prices, or differences between
prices, of securities, currencies, intangibles, goods, articles or commodities
(collectively "Underlying Assets") or by another objective index, economic
factor or other measure, such as interest rates, currency exchange rates,
commodity indices, and securities indices (collectively "Benchmarks"). Thus,
Hybrid Instruments may take a variety of forms, including, but not limited to,
debt instruments with interest or principal payments or redemption terms
determined by reference to the value of a currency or commodity or securities
index at a future point in time, preferred stock with dividend rates determined
by reference to the value of a currency, or convertible securities with the
conversion terms related to a particular commodity.

     Hybrid Instruments can be an efficient means of creating exposure to a
particular market, or segment of a market, with the objective of enhancing total
return. For example, a Fund may wish to take advantage of expected declines in
interest rates in several European countries, but avoid the transactions costs
associated with buying and currency-hedging the foreign bond positions. One
solution would be to purchase a U.S. dollar- denominated Hybrid Instrument whose
redemption price is linked to the average three year interest rate in a
designated group of countries. The redemption price formula would provide for
payoffs of greater than par if the average interest rate was lower than a
specified level, and payoffs of less than par if rates were above the specified
level. Furthermore, the Fund could limit the downside risk of the security by
establishing a minimum redemption price so that the principal paid at maturity
could not be below a predetermined minimum level if interest rates were to rise
significantly. The purpose of this arrangement, known as a structured security
with an embedded put option, would be to give the Fund the desired European bond
exposure while avoiding currency risk, limiting downside market risk, and
lowering transactions costs. Of course, there is no guarantee that the strategy
will be successful and the Fund could lose money if, for example, interest rates
do not move as anticipated or credit problems develop with the issuer of the
Hybrid.

     The risks of investing in Hybrid Instruments reflect a combination of the
risks of investing in securities, options, futures and currencies. Thus, an
investment in a Hybrid Instrument may entail significant risks that are not
associated with a similar investment in a traditional debt instrument that has a
fixed principal amount, is denominated in U.S. dollars or bears interest either
at a fixed rate or a floating rate determined by reference to a common,
nationally published Benchmark. The risks of a particular Hybrid Instrument
will, of course, depend upon the terms of the instrument, but may include,
without limitation, the possibility of significant changes in the Benchmarks or
the prices of Underlying Assets to which the instrument is linked. Such risks
generally depend upon factors which are unrelated to the operations or credit
quality of the issuer of the Hybrid Instrument and which may not be readily
foreseen by the purchaser, such as economic and political events, the supply and
demand for the Underlying Assets and interest rate movements.  In recent years,
various Benchmarks and prices for Underlying Assets have been highly volatile,
and 

                                      -17-
<PAGE>
 
such volatility may be expected in the future. Reference is also made to the
discussion below of futures, options, and forward contracts for a description of
certain risks associated with such investments.

     Hybrid Instruments are potentially more volatile and carry greater market
risks than traditional debt instruments.  Depending on the structure of the
particular Hybrid Instrument, changes in a Benchmark may be magnified by the
terms of the Hybrid Instrument and have an even more dramatic and substantial
effect upon the value of the Hybrid Instrument.  Also, the prices of the Hybrid
Instrument and the Benchmark or Underlying Asset may not move in the same
direction or at the same time.

     Hybrid Instruments may bear interest or pay preferred dividends at below
market (or even relatively nominal) rates. Alternatively, Hybrid Instruments may
bear interest at above market rates but bear an increased risk of principal loss
(or gain). The latter scenario may result if "leverage" is used to structure the
Hybrid Instrument. Leverage risk occurs when the Hybrid Instrument is structured
so that a given change in a Benchmark or Underlying Asset is multiplied to
produce a greater value change in the Hybrid Instrument, thereby magnifying the
risk of loss as well as the potential for gain.

     Hybrid Instruments may also carry liquidity risk since the instruments are
often "customized" to meet the portfolio needs of a particular investor, and
therefore, the number of investors that are willing and able to buy such
instruments in the secondary market may be smaller than that for more
traditional debt securities. In addition, because the purchase and sale of
Hybrid Instruments could take place in an over-the-counter market without the
guarantee of a central clearing organization or in a transaction between the
portfolio and the issuer of the Hybrid Instrument, the creditworthiness of the
counter party or issuer of the Hybrid Instrument would be an additional risk
factor which the portfolio would have to consider and monitor. Hybrid
Instruments also may not be subject to regulation of the Commodities Futures
Trading Commission ("CFTC"), which generally regulates the trading of commodity
futures by U.S. persons, the SEC, which regulates the offer and sale of
securities by and to U.S. persons, or any other governmental regulatory
authority. The various risks discussed above, particularly the market risk of
such instruments, may in turn cause significant fluctuations in the net asset
value of the Fund.

                   HEDGING AND OTHER STRATEGIC TRANSACTIONS

     A discussion of Hedging and Other Strategic Transactions follows. These
strategies will be used 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. No Fund which is authorized to use any of
these investment strategies will be obligated, however, to pursue any of such
strategies and no Fund makes any representation as to the availability of these
techniques at this time or at any time in the future. In addition, a Fund's
ability to pursue certain of these strategies may be limited by the Commodity
Exchange Act, as amended, applicable rules and regulations of the CFTC
thereunder and the federal income tax requirements applicable to regulated
investment companies which are not operated as commodity pools.

GENERAL CHARACTERISTICS OF OPTIONS

     Put options and call options typically have similar structural
characteristics and operational mechanics regardless of the underlying
instrument on which they are purchased or sold. Thus, the following general
discussion relates to each of the particular types of options discussed in
greater detail below. In addition, many Hedging and Other Strategic Transactions
involving options require segregation of Fund assets in special accounts.

     A put option gives the purchaser of the option, upon payment of a premium,
the right to sell, and the writer the obligation to buy, the underlying
security, commodity, index, currency or other instrument at the exercise price.
A Fund's purchase of a put option on a security, for example, might be designed
to protect its holdings in the underlying instrument (or, in some cases, a
similar instrument) against a substantial decline in the market value of such
instrument by giving the Fund the right to sell the instrument at the option
exercise price. A call option, upon payment of a premium, gives the purchaser of
the option the right to buy, and the seller the obligation to sell, the
underlying instrument at the exercise price. A Fund's purchase of a call option
on a security, financial futures contract, index, currency or other instrument
might be intended to protect the Fund against an increase in the price of the
underlying instrument that it intends to purchase in the future by fixing the
price at which it may purchase the instrument. An "American" style put or call
option may be exercised at any time during the option period, whereas a
"European" style put or call option may be exercised only upon expiration or
during a fixed period prior to expiration. Exchange-listed options are issued by
a regulated intermediary such as the Options Clearing Corporation ("OCC"), which
guarantees the performance of the obligations of the parties to the options. The
discussion below uses the OCC as an example, but is also applicable to other
similar financial intermediaries.

                                      -18-
<PAGE>
 
     OCC-issued and exchange-listed options, with certain exceptions, generally
settle by physical delivery of the underlying security or currency, although in
the future, cash settlement may become available. Index options and Eurodollar
instruments (which are described below under "Eurodollar Instruments") are cash
settled for the net amount, if any, by which the option is "in-the-money" (that
is, the amount by which the value of the underlying instrument exceeds, in the
case of a call option, or is less than, in the case of a put option, the
exercise price of the option) at the time the option is exercised. Frequently,
rather than taking or making delivery of the underlying instrument through the
process of exercising the option, listed options are closed by entering into
offsetting purchase or sale transactions that do not result in ownership of the
new option.

     A Fund's ability to close out its position as a purchaser or seller of an
OCC-issued or exchange-listed put or call option is dependent, in part, upon the
liquidity of the particular option market. Among the possible reasons for the
absence of a liquid option market on an exchange are: (1) insufficient trading
interest in certain options, (2) restrictions on transactions imposed by an
exchange, (3) trading halts, suspensions or other restrictions imposed with
respect to particular classes or series of options or underlying securities,
including reaching daily price limits, (4) interruption of the normal operations
of the OCC or an exchange, (5) inadequacy of the facilities of an exchange or
the OCC to handle current trading volume or (6) a decision by one or more
exchanges to discontinue the trading of options (or a particular class or series
of options), in which event the relevant market for that option on that exchange
would cease to exist, although any such outstanding options on that exchange
would continue to be exercisable in accordance with their terms.

     The hours of trading for listed options may not coincide with the hours
during which the underlying financial instruments are traded. To the extent that
the option markets close before the markets for the underlying financial
instruments, significant price and rate movements can take place in the
underlying markets that would not be reflected in the corresponding option
markets.

     Over-the-counter ("OTC") options are purchased from or sold to securities
dealers, financial institutions or other parties (collectively referred to as
"Counterparties" and individually referred to as a "Counterparty") through a
direct bilateral agreement with the Counterparty. In contrast to exchange-listed
options, which generally have standardized terms and performance mechanics, all
of the terms of an OTC option, including such terms as method of settlement,
term, exercise price, premium, guaranties and security, are determined by
negotiation of the parties. It is anticipated that any Fund authorized to use
OTC options will generally only enter into OTC options that have cash settlement
provisions, although it will not be required to do so.

     Unless the parties provide for it, no central clearing or guaranty function
is involved in an OTC option. As a result, if a Counterparty fails to make or
take delivery of the security, currency or other instrument underlying an OTC
option it has entered into with a Fund or fails to make a cash settlement
payment due in accordance with the terms of that option, the Fund will lose any
premium it paid for the option as well as any anticipated benefit of the
transaction. Thus, the Subadviser must assess the creditworthiness of each such
Counterparty or any guarantor or credit enhancement of the Counterparty's credit
to determine the likelihood that the terms of the OTC option will be met. A Fund
will enter into OTC option transactions only with U.S. Government securities
dealers recognized by the Federal Reserve Bank of New York as "primary dealers,"
or broker-dealers, domestic or foreign banks, or other financial institutions
that are deemed creditworthy by the Subadviser. In the absence of a change in
the current position of the staff of the Securities and Exchange Commission (the
"Commission"), OTC options purchased by a Fund and the amount of the Fund's
obligation pursuant to an OTC option sold by the Fund (the cost of the sell-back
plus the in-the-money amount, if any) or the value of the assets held to cover
such options will be deemed illiquid.

     If a Fund sells a call option, the premium that it receives may serve as a
partial hedge, to the extent of the option premium, against a decrease in the
value of the underlying securities or instruments held by the Fund or will
increase the Fund's income. Similarly, the sale of put options can also provide
Fund gains.

     If and to the extent authorized to do so, a Fund may purchase and sell call
options on securities and on Eurodollar instruments that are traded on U.S. and
foreign securities exchanges and in the OTC markets, and on securities indices,
currencies and futures contracts. All calls sold by a Fund must be "covered,"
that is, the Fund must own the securities subject to the call, must own an
offsetting option on a futures position, or must otherwise meet the asset
segregation requirements described below for so long as the call is outstanding.
Even though a Fund will receive the option premium to help protect it against
loss, a call sold by the Fund will expose the Fund during the term of the option
to possible loss of opportunity to realize appreciation in the market price of
the underlying security or instrument and may require the Fund to hold a
security or instrument that it might otherwise have sold.

     Each Fund reserves the right to purchase or sell options on instruments and
indices which may be developed in the future to the extent consistent with
applicable law, the Fund's investment objective and the restrictions set forth
herein.

                                      -19-
<PAGE>
 
     If and to the extent authorized to do so, a Fund may purchase and sell put
options on securities (whether or not it holds the securities in its portfolio)
and on securities indices, currencies and futures contracts. A Fund will not
sell put options if, as a result, more than 50% of the Fund's assets would be
required to be segregated to cover its potential obligations under put options
other than those with respect to futures contracts. In selling put options, a
Fund faces the risk that it may be required to buy the underlying security at a
disadvantageous price above the market price.

GENERAL CHARACTERISTICS OF FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS

     If and to the extent authorized to do so, a Fund may trade financial
futures contracts or purchase or sell put and call options on those contracts as
a hedge against anticipated interest rate, currency or market changes, for
duration management and for permissible non-hedging purposes. Futures contracts
are generally bought and sold on the commodities exchanges on which they are
listed with payment of initial and variation margin as described below. The sale
of a futures contract creates a firm obligation by a Fund, as seller, to deliver
to the buyer the specific type of financial instrument called for in the
contract at a specific future time for a specified price (or, with respect to
certain instruments, the net cash amount). Options on futures contracts are
similar to options on securities except that an option on a futures contract
gives the purchaser the right, in return for the premium paid, to assume a
position in a futures contract and obligates the seller to deliver that
position.

     A Fund's use of financial futures contracts and options thereon will in all
cases be consistent with applicable regulatory requirements and in particular
the rules and regulations of the CFTC and generally will be entered into only
for bona fide hedging, risk management (including duration management).
Maintaining a futures contract or selling an option on a futures contract will
typically require a Fund to deposit with a financial intermediary, as security
for its obligations, an amount of cash or other specified assets ("initial
margin") that initially is from 1% to 10% of the face amount of the contract
(but may be higher in some circumstances). Additional cash or assets ("variation
margin") may be required to be deposited thereafter daily as the mark-to-market
value of the futures contract fluctuates. The purchase of an option on a
financial futures contract involves payment of a premium for the option without
any further obligation on the part of a Fund. If a Fund exercises an option on a
futures contract it will be obligated to post initial margin (and potentially
variation margin) for the resulting futures position just as it would for any
futures position. Futures contracts and options thereon are generally settled by
entering into an offsetting transaction, but no assurance can be given that a
position can be offset prior to settlement or that delivery will occur.

     All of the Funds intend to comply with guidelines of  eligibility for
exclusion from the definition of the term "commodity pool operator" adopted by
the CFTC and the National Futures Association, which regulate trading in the
futures markets. A Fund will use futures contracts and related options, to the
extent otherwise permitted, primarily for bona fide hedging purposes within the
meaning of CFTC regulations. To the extent that a Fund holds positions in
futures contracts and related options that do not fall within the definition of
bona fide hedging transactions, the aggregate initial margins and premiums
required to establish such positions will not exceed 5% of the fair market value
of the Fund's net assets, after taking into account unrealized profits and
unrealized losses on any such contracts it has entered into.

     The value of all futures contracts sold by a Fund (adjusted for the
historical volatility relationship between such Fund and the contracts) will not
exceed the total market value of the Fund's securities.

OPTIONS ON SECURITIES INDICES AND OTHER FINANCIAL INDICES

     If and to the extent authorized to do so, a Fund may purchase and sell call
and put options on securities indices and other financial indices. In so doing,
the Fund can achieve many of the same objectives it would achieve through the
sale or purchase of options on individual securities or other instruments.
Options on securities indices and other financial indices are similar to options
on a security or other instrument except that, rather than settling by physical
delivery of the underlying instrument, options on indices settle by cash
settlement; that is, an option on an index gives the holder the right to
receive, upon exercise of the option, an amount of cash if the closing level of
the index upon which the option is based exceeds, in the case of a call, or is
less than, in the case of a put, the exercise price of the option (except if, in
the case of an OTC option, physical delivery is specified). This amount of cash
is equal to the excess of the closing price of the index over the exercise price
of the option, which also may be multiplied by a formula value. The seller of
the option is obligated, in return for the premium received, to make delivery of
this amount. The gain or loss on an option on an index depends on price
movements in the instruments comprising the market, market segment, industry or
other composite on which the underlying index is based, rather than price
movements in individual securities, as is the case with respect to options on
securities.

CURRENCY TRANSACTIONS

                                      -20-
<PAGE>
 
     If and to the extent authorized to do so, a Fund may engage in currency
transactions with Counterparties to hedge the value of portfolio securities
denominated in particular currencies against fluctuations in relative value.
Currency transactions include currency forward contracts, exchange-listed
currency futures contracts and options thereon, exchange-listed and OTC options
on currencies, and currency swaps.  A forward currency contract involves a
privately negotiated obligation to purchase or sell (with delivery generally
required) a specific currency at a future date, which may be any fixed number of
days from the date of the contract agreed upon by the parties, at a price set at
the time of the contract.  A currency swap is an agreement to exchange cash
flows based on the notional difference among two or more currencies and operates
similarly to an interest rate swap, which is described below under "Swaps, Caps,
Floors and Collars".  A Fund may enter into currency transactions only with
Counterparties that are deemed creditworthy by the Subadviser.

     A Fund's dealings in forward currency contracts and other currency
transactions such as futures contracts, options, options on futures contracts
and swaps will be limited to hedging and other non-speculative purposes,
including transaction hedging and position hedging.  Transaction hedging is
entering into a currency transaction with respect to specific assets or
liabilities of a Fund, which will generally arise in connection with the
purchase or sale of the Fund's portfolio securities or the receipt of income
from them.  Position hedging is entering into a currency transaction with
respect to portfolio securities positions denominated or generally quoted in
that currency.  A Fund will not enter into a transaction to hedge currency
exposure to an extent greater, after netting all transactions intended wholly or
partially to offset other transactions, than the aggregate market value (at the
time of entering into the transaction) of the securities held by the Fund that
are denominated or generally quoted in or currently convertible into the
currency, other than with respect to proxy hedging as described below.

     A Fund may cross-hedge currencies by entering into transactions to purchase
or sell one or more currencies that are expected to increase or decline in value
relative to other currencies to which the Fund has or in which the Fund expects
to have exposure.  To reduce the effect of currency fluctuations on the value of
existing or anticipated holdings of its securities, a Fund may also engage in
proxy hedging.  Proxy hedging is often used when the currency to which a Fund's
holdings is exposed is difficult to hedge generally or difficult to hedge
against the dollar.  Proxy hedging entails entering into a forward contract to
sell a currency, the changes in the value of which are generally considered to
be linked to a currency or currencies in which some or all of a Fund's
securities are or are expected to be denominated, and to buy dollars.  The
amount of the contract would not exceed the market value of the Fund's
securities denominated in linked currencies.

     Currency transactions are subject to risks different from other portfolio
transactions, as discussed below under "Risk Factors."

COMBINED TRANSACTIONS

     If and to the extent authorized to do so, a Fund may enter into multiple
transactions, including multiple options transactions, multiple futures
transactions, multiple currency transactions (including forward currency
contracts), multiple interest rate transactions and any combination of futures,
options, currency and interest rate transactions, instead of a single Hedging
and Other Strategic Transaction, as part of a single or combined strategy when,
in the judgment of the Subadviser, it is in the best interests of the Fund to do
so.  A combined transaction will usually contain elements of risk that are
present in each of its component transactions.  Although combined transactions
will normally be entered into by a Fund based on the Subadviser's judgment that
the combined strategies will reduce risk or otherwise more effectively achieve
the desired portfolio management goal, it is possible that the combination will
instead increase the risks or hinder achievement of the portfolio management
objective.

SWAPS, CAPS, FLOORS AND COLLARS

     A Fund may be authorized to enter into interest rate, currency and index
swaps, the purchase or sale of related caps, floors and collars and other
derivatives.  A Fund will enter into these transactions primarily to seek to
preserve a return or spread on a particular investment or portion of its
portfolio, to protect against currency fluctuations, as a duration management
technique or to protect against any increase in the price of securities a Fund
anticipates purchasing at a later date.  A Fund will use these transactions for
non-speculative purposes and will not sell interest rate caps or floors if it
does not own securities or other instruments providing the income the Fund may
be obligated to pay.  Interest rate swaps involve the exchange by a Fund with
another party of their respective commitments to pay or receive interest (for
example, an exchange of floating rate payments for fixed rate payments with
respect to a notional amount of principal).  A currency swap is an agreement to
exchange cash flows on a notional amount based on changes in the values of the
reference indices.  The purchase of a cap entitles the purchaser to receive
payments on a notional principal amount from the party selling the cap to the
extent that a specified index exceeds a predetermined interest rate.  The
purchase of an interest rate floor entitles the purchaser to receive payments of
interest on a notional principal amount from the party selling the interest rate
floor to the extent that a specified index falls below a predetermined interest
rate or amount. The purchase of a floor entitles the purchaser to receive
payments on a notional principal amount from the party selling

                                      -21-
<PAGE>
 
the floor to the extent that a specific index falls below a predetermined
interest rate or amount. A collar is a combination of a cap and a floor that
preserves a certain return with a predetermined range of interest rates or
values.

     A Fund will usually enter into interest rate swaps on a net basis, that is,
the two payment streams are netted out in a cash settlement on the payment date
or dates specified in the instrument, with the Fund receiving or paying, as the
case may be, only the net amount of the two payments.  Inasmuch as these swaps,
caps, floors, collars and other similar derivatives are entered into for good
faith hedging or other non-speculative purposes, they do not constitute senior
securities under the Investment Company Act of 1940, as amended (the "1940
Act"), and, thus, will not be treated as being subject to the Fund's borrowing
restrictions.  A Fund will not enter into any swap, cap, floor, collar or other
derivative transaction unless the Counterparty is deemed creditworthy by the
Subadviser.  If a Counterparty defaults, a Fund may have contractual remedies
pursuant to the agreements related to the transaction.  The swap market has
grown substantially in recent years with a large number of banks and investment
banking firms acting both as principals and as agents utilizing standardized
swap documentation.  As a result, the swap market has become relatively liquid.
Caps, floors and collars are more recent innovations for which standardized
documentation has not yet been fully developed and, for that reason, they are
less liquid than swaps.

     The liquidity of swap agreements will be determined by a Subadviser based
on various factors, including (1) the frequency of trades and quotations, (2)
the number of dealers and prospective purchasers in the marketplace, (3) dealer
undertakings to make a market, (4) the nature of the security (including any
demand or tender features), and (5) the nature of the marketplace for trades
(including the ability to assign or offset a Fund's rights and obligations
relating to the investment).  Such determination will govern whether a swap will
be deemed to be within the 10% (or 15% with respect to the Emerging Growth Fund
and the Tax-Sensitive Equity Fund) restriction on investments in securities that
are not readily marketable.

     Each Fund will maintain cash and appropriate liquid assets in a segregated
custodial account to cover its current obligations under swap agreements. If a
Fund enters into a swap agreement on a net basis, it will segregate assets with
a daily value at least equal to the excess, if any, of the Fund's accrued
obligations under the swap agreement over the accrued amount the Fund is
entitled to receive under the agreement.  If a Fund enters into a swap agreement
on other than a net basis, it will segregate assets with a value equal to the
full amount of the Fund's accrued obligations under the agreement.  See "Use of
Segregated and Other Special Accounts."

EURODOLLAR INSTRUMENTS

     If and to the extent authorized to do so, a Fund may make investments in
Eurodollar instruments, which are typically dollar-denominated futures contracts
or options on those contracts that are linked to the London Interbank Offered
Rate ("LIBOR"), although foreign currency denominated instruments are available
from time to time.  Eurodollar futures contracts enable purchasers to obtain a
fixed rate for the lending of funds and sellers to obtain a fixed rate for
borrowings.  A Fund might use Eurodollar futures contracts and options thereon
to hedge against changes in LIBOR, to which many interest rate swaps and fixed
income instruments are linked.

RISK FACTORS

     Hedging and Other Strategic Transactions have special risks associated with
them, including possible default by the Counterparty to the transaction,
illiquidity and, to the extent the Subadviser's view as to certain market
movements is incorrect, the risk that the use of the Hedging and Other Strategic
Transactions could result in losses greater than if they had not been used.  Use
of put and call options could result in losses to a Fund, force the sale or
purchase of portfolio securities at inopportune times or for prices higher than
(in the case of put options) or lower than (in the case of call options) current
market values, or cause a Fund to hold a security it might otherwise sell.

     The use of futures and options transactions entails certain special risks.
In particular, the variable degree of correlation between price movements of
futures contracts and price movements in the related securities position of a
Fund could create the possibility that losses on the hedging instrument are
greater than gains in the value of the Fund's position.  In addition, futures
and options markets could be illiquid in some circumstances and certain over-
the-counter options could have no markets.  As a result, in certain markets, a
Fund might not be able to close out a transaction without incurring substantial
losses.  Although a Fund's use of futures and options transactions for hedging
should tend to minimize the risk of loss due to a decline in the value of the
hedged position, at the same time it will tend to limit any potential gain to a
Fund that might result from an increase in value of the position.  Finally, the
daily variation margin requirements for futures contracts create a greater
ongoing potential financial risk than would purchases of options, in which case
the exposure is limited to the cost of the initial premium.

                                      -22-
<PAGE>
 
     Currency hedging involves some of the same risks and considerations as
other transactions with similar instruments.  Currency transactions can result
in losses to a Fund if the currency being hedged fluctuates in value to a degree
or in a direction that is not anticipated.  Further, the risk exists that the
perceived linkage between various currencies may not be present or may not be
present during the particular time that a Fund is engaging in proxy hedging.
Currency transactions are also subject to risks different from those of other
portfolio transactions.  Because currency control is of great importance to the
issuing governments and influences economic planning and policy, purchases and
sales of currency and related instruments can be adversely affected by
government exchange controls, limitations or restrictions on repatriation of
currency, and manipulations or exchange restrictions imposed by governments.
These forms of governmental actions can result in losses to a Fund if it is
unable to deliver or receive currency or monies in settlement of obligations and
could also cause hedges it has entered into to be rendered useless, resulting in
full currency exposure as well as incurring transaction costs.  Buyers and
sellers of currency futures contracts are subject to the same risks that apply
to the use of futures contracts generally.  Further, settlement of a currency
futures contract for the purchase of most currencies must occur at a bank based
in the issuing nation.  Trading options on currency futures contracts is
relatively new, and the ability to establish and close out positions on these
options is subject to the maintenance of a liquid market that may not always be
available.  Currency exchange rates may fluctuate based on factors extrinsic to
that country's economy.

     Losses resulting from the use of Hedging and Other Strategic Transactions
will reduce a Fund's net asset value, and possibly income, and the losses can be
greater than if Hedging and Other Strategic Transactions had not been used.

RISKS OF HEDGING AND OTHER STRATEGIC TRANSACTIONS OUTSIDE THE UNITED STATES

     When conducted outside the United States, Hedging and Other Strategic
Transactions may not be regulated as rigorously as in the United States, may not
involve a clearing mechanism and related guarantees, and will be subject to the
risk of governmental actions affecting trading in, or the prices of, foreign
securities, currencies and other instruments.  The value of positions taken as
part of non-U.S. Hedging and Other Strategic Transactions also could be
adversely affected by:  (1) other complex foreign political, legal and economic
factors, (2) lesser availability of data on which to make trading decisions than
in the United States, (3) delays in a Fund's ability to act upon economic events
occurring in foreign markets during non-business hours in the United States, (4)
the imposition of different exercise and settlement terms and procedures and
margin requirements than in the United States and (5) lower trading volume and
liquidity.

USE OF SEGREGATED AND OTHER SPECIAL ACCOUNTS

     Use of many Hedging and Other Strategic Transactions by a Fund will
require, among other things, that the Fund segregate cash or other liquid assets
with its custodian, or a designated sub-custodian, to the extent the Fund's
obligations are not otherwise "covered" through ownership of the underlying
security, financial instrument or currency.  In general, either the full amount
of any obligation by a Fund to pay or deliver securities or assets must be
covered at all times by the securities, instruments or currency required to be
delivered, or, subject to any regulatory restrictions, an amount of cash or
other liquid assets equal to the current amount of the obligation must be
segregated with the custodian or sub-custodian.  The segregated assets cannot be
sold or transferred unless equivalent assets are substituted in their place or
it is no longer necessary to segregate them.  A call option on securities
written by a Fund, for example, will require the Fund to hold the securities
subject to the call (or securities convertible into the needed securities
without additional consideration) or to segregate liquid assets sufficient to
purchase and deliver the securities if the call is exercised.  A call option
sold by a Fund on an index will require the Fund to own portfolio securities
that correlate with the index or to segregate liquid assets equal to the excess
of the index value over the exercise price on a current basis.  A put option on
securities written by a Fund will require the Fund to segregate liquid assets
equal to the exercise price.  Except when a Fund enters into a forward contract
in connection with the purchase or sale of a security denominated in a foreign
currency or for other non-speculative purposes, which requires no segregation, a
currency contract that obligates the Fund to buy or sell a foreign currency will
generally require the Fund to hold an amount of that currency, liquid securities
denominated in that currency equal to a Fund's obligations or to segregate
liquid assets equal to the amount of the Fund's obligations.

     OTC options entered into by a Fund, including those on securities,
currency, financial instruments or indices, and OCC-issued and exchange-listed
index options will generally provide for cash settlement, although a Fund will
not be required to do so.  As a result, when a Fund sells these instruments it
will segregate an amount of assets equal to its obligations under the options.
OCC-issued and exchange-listed options sold by a Fund other than those described
above generally settle with physical delivery, and the Fund will segregate an
amount of assets equal to the full value of the option.  OTC options settling
with physical delivery or with an election of either physical delivery or cash
settlement will be treated the same as other options settling with physical
delivery.

     In the case of a futures contract or an option on a futures contract, a
Fund must deposit initial margin and, in some instances, daily variation margin
in addition to segregating assets sufficient to meet its obligations to purchase
or provide securities 

                                      -23-

or currencies, or to pay the amount owed at the expiration of an index-based
futures contract. These assets may consist of cash, cash equivalents, liquid
high grade debt or equity securities or other acceptable assets. A Fund will
accrue the net amount of the excess, if any, of its obligations relating to
swaps over its entitlements with respect to each swap on a daily basis and will
segregate with its custodian, or designated sub-custodian, an amount of cash or
liquid assets having an aggregate value equal to at least the accrued excess.
Caps, floors and collars require segregation of assets with a value equal to a
Fund's net obligation, if any.

     Hedging and Other Strategic Transactions may be covered by means other than
those described above when consistent with applicable regulatory policies.  A
Fund may also enter into offsetting transactions so that its combined position,
coupled with any segregated assets, equals its net outstanding obligation in
related options and Hedging and Other Strategic Transactions.  A Fund could
purchase a put option, for example, if the strike price of that option is the
same or higher than the strike price of a put option sold by the Fund.
Moreover, instead of segregating assets if it holds a futures contracts or
forward contract, a Fund could purchase a put option on the same futures
contract or forward contract with a strike price as high or higher than the
price of the contract held.  Other Hedging and Other Strategic Transactions may
also be offset in combinations.  If the offsetting transaction terminates at the
time of or after the primary transaction, no segregation is required, but if it
terminates prior to that time, assets equal to any remaining obligation would
need to be segregated.

OTHER LIMITATIONS

     No Fund will maintain open short positions in futures contracts, call
options written on futures contracts, and call options written on securities
indices if, in the aggregate, the current market value of the open positions
exceeds the current market value of that portion of its securities portfolio
being hedged by those futures and options plus or minus the unrealized gain or
loss on those open positions, adjusted for the historical volatility
relationship between that portion of the Fund and the contracts (e.g., the Beta
volatility factor).  For purposes of the limitation stated in the immediately
preceding sentence, to the extent the Fund has written call options on specific
securities in that portion of its portfolio, the value of those securities will
be deducted from the current market value of that portion of the securities
portfolio.  If this limitation should be exceeded at any time, the Fund will
take prompt action to close out the appropriate number of open short positions
to bring its open futures and options positions within this limitation.

WARRANT TRANSACTIONS AND RISKS

     Each of the Funds (other than the Money Market Fund) may purchase warrants,
including warrants traded independently of the underlying securities. Such
transactions entail certain risks. A warrant is a security, usually issued
together with a bond or preferred stock, that entitles the holder to buy a
proportionate amount of common stock at a specified price, usually higher than
the market price at the time of issuance, for a period of years or to
perpetuity.   In contrast, rights, which also represent the right to buy common
shares, normally have a subscription price lower than the current market value
of the common stock and a life of two to four weeks.  A warrant is usually
issued as a sweetener, to enhance the marketability of the accompanying fixed
income securities. Warrants may be considered more speculative than certain
other types of investments in that prior to their exercise they do not entitle a
holder to dividends and voting rights with respect to the securities which may
be purchased by the exercise thereof, nor do they represent any rights in the
assets of the issuing company. Also, the value of the warrant does not
necessarily change with the value of the underlying security. If a warrant
expires unexercised, the Fund will lose the amount paid for the warrant and any
transaction costs.

                            INVESTMENT RESTRICTIONS

     There are two classes of investment restrictions to which the Trust is
subject in implementing the investment policies of the Funds:  fundamental and
nonfundamental.  Nonfundamental restrictions are subject to change by the
Trustees of a Fund without shareholder approval.  Fundamental restrictions may
only be changed by a shareholder vote.

     The Trust may not issue senior securities, except to the extent that the
borrowing of money in accordance with restriction  (3) may constitute the
issuance of a senior security.  (For purposes of this restriction, purchasing
securities on a when-issued or delayed delivery basis and engaging in Hedging
and Other Strategic Transactions will not be deemed to constitute the issuance
of a senior security.)  In addition, unless a Fund is specifically excepted by
the terms of a restriction, each Fund will not:

FUNDAMENTAL

     (1) Invest more than 25% of the value of its total assets in securities of
issuers having their principal activities in any particular industry, excluding
U.S. Government securities and, with respect to the Money Market Fund,
obligations of domestic branches of U.S. banks and with respect to the National
Municipal Bond Fund, obligations issued or guaranteed by the U.S. 

                                      -24-
<PAGE>
 
Government, its agencies or instrumentalities or by any state, territory or any
possession of the United States, the District of Columbia, or any of their
authorities, agencies, instrumentalities or political subdivisions, or with
respect to repurchase agreements collateralized by any of such obligations. For
purposes of this restriction (except with regard to the Emerging Growth Fund),
supranational issuers will be considered to comprise an industry as will each
foreign government that issues securities purchased by a Fund.

     (2)  Purchase the securities of any issuer if the purchase would cause more
than 5% of the value of the Fund's total assets to be invested in the securities
of any one issuer (excluding U.S. Government securities) or cause more than 10%
of the voting securities of the issuer to be held by the Fund, except that up to
25% of the value of each Fund's total assets may be invested without regard to
these restrictions.  This restriction does not apply to the Emerging Growth Fund
as a non-diversified portfolio.

     (3)  Borrow money except that each Fund may borrow (i) for temporary or
emergency purposes (not for leveraging) up to 33 1/3% of the value of the Fund's
total assets (including amounts borrowed) less liabilities (other than
borrowings) and (ii) in connection with reverse repurchase agreements, mortgage
dollar rolls and other similar transactions.

     (4)  Underwrite securities of other issuers except insofar as the Fund may
be considered an underwriter under the Securities Act of 1933 in selling
portfolio securities.

     (5)  Purchase or sell real estate, except that each Fund may invest in
securities issued by companies which invest in real estate or interests therein
and each of the Funds other than the Money Market Fund may invest in mortgages
and mortgage-backed securities.

     (6)  Purchase or sell commodities or commodity contracts except that each
Fund other than the Investment Quality Bond and Money Market Funds may purchase
and sell futures contracts on financial instruments and indices and options on
such futures contracts.  The Tax-Sensitive Equity, Emerging Growth, Equity-
Income, Small/Mid Cap, International Small Cap, Growth Equity, Global Equity,
Strategic Income and International Growth and Income Funds may purchase and sell
futures contracts on foreign currencies and options on such futures contracts.
The U.S. Government Securities Fund has elected for the present to not engage in
the purchase or sale of commodities or commodity contracts to the extent
permitted by this restriction, but it reserves the right to engage in such
transactions at a future time.

     (7)  Lend money to other persons except by the purchase of obligations in
which the Fund is authorized to invest and by entering into repurchase
agreements.  For purposes of this restriction, collateral arrangements with
respect to options, forward currency and futures transactions will not be deemed
to involve the lending of money.

     (8)  Lend securities in excess of 33% of the value of its total non-cash
assets.  For purposes of this restriction, collateral arrangements with respect
to options, forward currency and futures transactions will not be deemed to
involve loans of securities.

NONFUNDAMENTAL

     (9)  Knowingly invest more than 10% of the value of its net assets in
securities or other investments not readily marketable, including repurchase
agreements maturing in more than seven days but excluding variable amount master
demand notes, except that the  Tax-Sensitive Equity Fund and the Emerging Growth
Fund may so invest up to 15% its net assets.

     (10) Purchase securities for the purpose of exercising control or
management.

     (11) Purchase securities of foreign issuers, except that (A) the Tax-
Sensitive Equity Fund, International Small Cap, Global Equity, International
Growth and Income and Strategic Income Funds may each, without limitation,
invest up to 100% of its assets in securities issued by foreign entities and/or
denominated in foreign currencies, (B) the Balanced Fund and Growth Equity Fund
may each invest up to 30% of its assets in such securities, (C) the Emerging
Growth Fund and the Equity-Income Fund may invest up to 25% of its assets in
such securities, and (D) each of the other portfolios (other than the U.S.
Government Securities and National Municipal Bond Funds) may invest up to 20% of
its assets in securities issued by foreign entities and/or denominated in
foreign currencies.  (In the case of the Small/Mid Cap, Growth Equity and
Balanced Funds, ADRs and U.S. dollar denominated securities are not included in
the percentage limitation.)

     In addition to the above policies, the Money Market Fund is subject to
certain restrictions required by Rule 2a-7 under the 1940 Act.

     For the purposes of the investment limitations applicable to the National
Municipal Bond Fund, the identification of the issuer of a municipal obligation
depends on the terms and conditions of the obligation.  If the assets and
revenues of an agency, 

                                      -25-
<PAGE>
 
authority, instrumentality, or other political subdivision are separate from
those of the government creating the subdivision and the obligation is backed
only by the assets and revenues of the subdivision, such subdivision would be
regarded as the sole issuer. Similarly, in the case of a private activity bond,
if the bond is backed only by the assets and revenues of the non-governmental
user, such non-governmental user would be regarded as the sole issuer. If in
either case the creating government or another entity guarantees an obligation,
the guarantee would be considered a separate security and treated as an issue of
such government or entity.

     If a percentage restriction is adhered to at the time of an investment, a
later increase or decrease in the investment's percentage of the value of a
Fund's total assets resulting from a change in such values or assets will not
constitute a violation of the percentage restriction, except in the case of the
Money Market Fund where the percentage limitation of restriction (9) must be met
at all times.


                              PORTFOLIO TURNOVER

     The annual rate of portfolio turnover will normally differ for each Fund
and may vary from year to year.  Portfolio turnover is calculated by dividing
the lesser of purchases or sales of portfolio securities during the fiscal year
by the monthly average of the value of the Fund's securities (excluding from the
computation all securities, including options, with maturities at the time of
acquisition of one year or less).  A high rate of portfolio turnover generally
involves correspondingly greater brokerage commission expenses, which must be
borne directly by the Fund.  No portfolio turnover rate can be calculated for
the Money Market Fund due to the short maturities of the instruments purchased.
The portfolio turnover rates for the periods shown below were as follows:

     Prior rates of portfolio turnover do not provide an accurate guide as to
what the rate will be in any future year, and prior rates and estimated rates
are not a limiting factor when it is deemed appropriate to purchase or sell
securities for a Fund.

                      INVESTMENT MANAGEMENT ARRANGEMENTS

     The following information supplements the material appearing in the
Prospectus.

ADVISORY ARRANGEMENTS

     CypressTree Investments, Inc. is a subsidiary of Cypress Holding Company,
Inc., which is controlled by its management and by Berkshire Partners IV, L.P.
CypressTree Investments Inc. and its affiliates, CypressTree Asset Management
Corporation, Inc. ("CAM") and CypressTree Funds Distributors, Inc. ("CFD"), were
formed in 1996 to acquire, advise and distribute mutual funds through broker
dealers, banks and other intermediaries. CAM acts as the Fund's investment
adviser (the "Adviser"), while CFD acts as the Fund's distributor (the
"Distributor"). Until August 1, 1998, CFD was party to a promotional agent
agreement with Wood Logan Associates, Inc. ("Wood Logan") to provide marketing
services in connection with the sales of Fund's shares.

     Prior to October 1, 1997, NASL Financial Services, Inc. was both the
investment adviser and the distributor for the Fund (in such capacity, the
"Former Distributor"). Standish, Ayer & Wood, Inc., subadviser to the Tax-
Sensitive Equity Fund, owns 20% of CypressTree Investments, Inc.

     The Adviser oversees all aspects of the Fund's business and affairs. In
that connection, the Adviser permits its directors, officers and employees to
serve as Trustees or President, Vice President, Treasurer or Secretary of the
Fund, without cost to the Fund. The Adviser also provides certain services, and
the personnel to perform such services, to the Fund for which the Fund
reimburses the Adviser's costs of providing such services and personnel. Such
services include maintaining certain records of the Fund and performing all
administrative, financial, accounting, bookkeeping and recordkeeping functions
of the Fund, except for any of those functions performed by the Fund's custodian
or transfer and shareholder servicing agents. The reimbursement paid by the Fund
to the Adviser for personnel costs include employee compensation and allocated
portions of the Adviser's related personnel expenses of office space, utilities,
office equipment and miscellaneous office expenses.

     As compensation for its services, the Adviser receives a fee from the Trust
computed separately for each Fund. The fee for each Fund is stated as an annual
percentage of the current value of the net assets of the Fund. The fee, which is
accrued daily and payable monthly, is calculated for each day by multiplying the
fraction of one over the number of calendar days in the year by the annual
percentage prescribed for a Fund, and multiplying this product by the value of
the net assets of the Fund at the close of business on the previous business day
of the Fund.

     The Advisory Agreement, each Subadvisory Agreement and the Salomon Brothers
Asset Management Limited Consulting Agreement, each dated October 1, 1997, were
approved by the Trustees on June 27, 1997 and by the shareholders of the Funds
on September 24, 1997, in connection with the acquisition (the "Acquisition") of
the business of NASL Financial Services, Inc. relating to acting as investment
adviser and distributor of the Fund by CypressTree Investments, Inc., with the
exceptions of the Subadvisory Agreements for the Tax-Sensitive Equity Fund and
the Emerging Growth Fund. Subadvisory Agreements between the Advisor and
Standish, Ayer & Wood, Inc. and Warburg Pincus Asset Management, Inc. were
approved by the Trustees on December 16, 1997 in conjunction with the addition
of the Tax-Sensitive Equity Fund and Emerging Growth Fund, respectively.

     The following is a schedule of the management fees each Fund currently is
obligated to pay CAM under the Advisory Agreement (prior to the application of
any fee waivers):

     CAM has agreed to reduce each Fund's advisory fee, or if necessary to
reimburse the Trust, in order to prevent the expenses of a Fund from exceeding a
fixed expense limitation contained in the Advisory Agreement. The fixed
limitation may be terminated by CAM at any time on 30 days' written notice. The
fixed limitation contained in the Advisory Agreement, which is the operative
limitation on the Fund's expenses, limits each Fund's annual expenses, excluding
taxes, Fund brokerage commissions, interest, certain litigation and
indemnification expenses, extraordinary expenses and all of the Fund's
distribution fees as a percentage of average net assets to the following:

SUBADVISORY ARRANGEMENTS

     Under the terms of each of the Subadvisory agreements between the Adviser
and a Subadviser (the "Subadvisory Agreements"), the Subadviser assigned to a
Fund manages the investment and reinvestment of the assets of such Fund, subject
to the supervision of the Trustees. The Subadviser formulates a continuous
investment program for such Fund consistent with its investment objectives and
policies outlined in this Prospectus. The Subadviser implements such programs by
purchases and sales of securities and regularly reports to the Adviser and the
Trustees with respect to their implementation.

     As compensation for their services, the Subadvisers receive fees from the
Adviser computed separately for each Fund. The fee for each Fund is stated as an
annual percentage of the current value of the net assets of the Fund. The fee,
which is accrued daily and payable monthly, is calculated for each day by
multiplying the fraction of one over the number of calendar days in the year by
the annual percentage prescribed for a Fund, and multiplying this product by the
value of the net assets of the Fund at the close of business on the previous
business day of the Fund. Once the average net assets of a Fund exceed specified
amounts, the fee is reduced with respect to the excess. Absent any applicable
fee waivers, the following is a schedule of the management fees the Adviser is
obligated to pay the Subadvisers for each Fund under the Subadvisory Agreements.
THESE FEES ARE PAID BY THE ADVISER AND ARE NOT ADDITIONAL CHARGES TO THE FUNDS
OR THEIR SHAREHOLDERS.

     The following is a schedule of fees paid by the Adviser to the Subadvisers.

     The Advisory Agreement and each Subadvisory Agreement, including the SBAM
Limited Consulting Agreement (collectively, the "Agreements") will continue in
effect as to a Fund for a period no more than two years from the date of its
execution or the execution of an amendment making the agreement applicable to
that Fund only so long as such continuance is specifically approved at least
annually either by the Trustees or by the vote of a majority of the outstanding
voting securities of each of the Funds of the Fund, provided that in either
event such continuance shall also be approved by the vote of the majority of the
Trustees who are not interested persons of any party to the Agreements, cast in
person at a meeting called for the purpose of voting on such approval.  The
required shareholder approval of any continuance of any of the Agreements shall
be effective with respect to any Fund if a majority of the outstanding voting
securities of the class of capital stock of that Fund vote to approve such
continuance, notwithstanding that such continuance may not have been approved by
a majority of the outstanding voting securities of the Fund.

     If the shareholders of any Fund fail to approve any continuance of any
Agreement, the Adviser or Subadviser (including SBAM Limited), as applicable,
will continue to act as such with respect to such Fund pending the required
approval of the continuance of such Agreement, of a new contract with the
Adviser or Subadviser or different investment adviser or subadviser, or other
definitive action.  In the case of the Adviser, the compensation received in
respect of such a Fund during such period will be no more than its actual costs
incurred in furnishing investment advisory and management services to such Fund
or the amount it would have received under the Agreement in respect of such
Fund, whichever is less.  In the case of the Subadvisers, the compensation
received by them in respect of such a Fund during such a period will be no more
than that permitted by Rule 15a-4 under the 1940 Act.

                                      -40-

     The Agreements may be terminated at any time, without the payment of
penalty, by the Trustees or by the vote of a majority of the outstanding voting
securities of the applicable Fund of the Trust, with respect to any Fund by the
vote of a majority of the outstanding shares of such Fund, or by the Adviser or
applicable Subadviser on 60 days' written notice to the other party or parties
to the Agreement and, in the case of the Subadvisory Agreements, to the Fund.
Each of the Agreements will automatically terminate in the event of its
assignment.

     The Agreements may be amended by the parties provided that such amendment
is specifically approved by the vote of a majority of the outstanding voting
securities of the Trust or applicable Fund(s), as the case may be, and by the
vote of a majority of the Trustees who are not interested persons of the Trust,
of the Adviser or of the applicable Subadviser or of SBAM Limited, cast in
person at a meeting called for the purpose of voting upon such approval. The
required shareholder approval of any amendment shall be effective with respect
to any Fund if a majority of the outstanding voting securities of that Fund vote
to approve the amendment, notwithstanding that the amendment may not be approved
by a majority of the outstanding voting securities of (i) any other Fund
affected by the amendment or (ii) all the Funds of the Trust.

     Each Subadvisory Agreement, except the J.P. Morgan Subadvisory Agreement
and the SBAM Limited Consulting Agreement, provides that the Subadviser or SBAM
Limited will not be liable to the Trust or the Adviser for any losses resulting
from any matters to which the agreement relates other than losses resulting from
the Subadviser's or SBAM Limited's willful misfeasance, bad faith or gross
negligence in the performance of, or from reckless disregard of, its duties. The
J.P. Morgan Subadvisory Agreement provides that the subadviser will not be
liable to the Trust or CAM for any losses resulting from any error of judgment
made in the good faith exercise of the Subadviser's investment discretion in
connection with selecting investments, except for losses resulting from willful
misfeasance, bad faith or gross negligence of, or from reckless disregard of, it
duties, and that it shall not be liable for any losses resulting from any other
matters except for losses resulting from willful misfeasance, bad faith or
negligence in the performance of, or from disregard of, its duties.

obligation to indemnify its Trustees, officers and agents. All expenses are
accrued daily and deducted from total income before dividends are paid.

                              DISTRIBUTION PLANS

     The Trust currently offers three classes of shares in each Fund: "Class A"
shares, "Class B" shares and "Class C" shares.

     In addition to the front end sales charge which may be deducted at the time
of purchase of Class A shares and the CDSC which may apply on redemption of
Class B shares, each class of shares of each Fund is authorized under the
Distribution Plan applicable to that class of shares (the "Class A Plan," the
"Class B Plan" and the "Class C Plan," collectively, the "Plans") adopted
pursuant to Rule 12b-1 under the 1940 Act to use the assets attributable to such
class of shares of the Fund to finance certain activities relating to the
distribution of shares to investors. The Plans are "compensation" plans
providing for the payment of a fixed percentage of average net assets to finance
distribution expenses. The Plans provide for the payment by each class of shares
of each Fund of the Trust, other than the Money Market Fund, of a monthly
distribution and service fee to the Distributor, as principal underwriter for
the Fund. Portions of the fees prescribed

                                      -41-

below are used to provide payments to the Distributor, to promotional agents, to
brokers, dealers or financial institutions (collectively, "Selling Agents") and
to Service Organizations for ongoing account services to shareholders and are
deemed to be "service fees" as defined in paragraph (b)(9) of Section 2830 of
the Conduct Rules of the National Association of Securities Dealers, Inc.

     Under the Class A Plan, Class A shares of each Fund (except as described in
the next sentence) are subject to a fee of up to .35% of their respective
average annual net assets, five-sevenths of which (.25%) constitutes a "service
fee."  Class A shares of the National Municipal Bond Fund are subject to a fee
of up to .15% of Class A average annual net assets, the entire amount of which
constitutes a "service fee," and Class A shares of the Money Market Fund bear no
such fees.  Under the Class B Plan, Class B shares of each Fund (with the
exception of the Money Market Fund) are subject to a fee of up to 1.00% of their
respective average annual net assets, one-fourth (.25%) of which constitutes a
"service fee."  Under the Class C Plan, Class C shares of each Fund (with the
exception of the Money Market Fund) are subject to a fee of up to 1.00% of their
respective average annual net assets, one-fourth (.25%) of which constitutes a
"service fee."

     Payments under the Plans are used primarily to compensate the Distributor
for distribution services provided by it in connection with the offering and
sale of the applicable class of shares, and related expenses incurred, including
payments by the Distributor to compensate or reimburse Selling Agents for sales
support services provided and related expenses incurred by such Selling Agents.
Such services and expenses may include the development, formulation and
implementation of marketing and promotional activities, the preparation,
printing and distribution of prospectuses and reports to recipients other than
existing shareholders, the preparation, printing and distribution of sales
literature, expenditures for support services such as telephone facilities and
expenses and shareholder services as the Trust may reasonably request, provision
to the Trust of such information, analyses and opinions with respect to
marketing and promotional activities as the Trust may, from time to time,
reasonably request, commissions, incentive compensation or other compensation
to, and expenses of, account executives or other employees of the Distributor or
Selling Agents, attributable to distribution or sales support activities,
respectively, overhead and other office expenses of the Distributor or Selling
Agents, attributable to distribution or sales support activities, respectively,
and any other costs and expenses relating to distribution or sales support
activities.  The Distributor may pay directly Selling Agents and may provide
directly the distribution services described above (prior to August 1, 1998, it
arranged for such payment or the performance of some or all of such services by
Wood Logan, the Trust's promotional agent, at such level of compensation as had
been agreed to by the Distributor and Wood Logan).

     The distribution and service fees attributable to the Class B shares and
Class C shares are designed to permit an investor to purchase shares without the
assessment of a front end sales charge, and, with respect to the Class C shares,
without the assessment of a front end sales charge or a CDSC, and at the same
time permit the Distributor to compensate securities dealers with respect to
sales of such shares.

     The Distributor is authorized by each Plan to retain any excess of the fees
it receives thereunder over its payments to selected dealers and its expenses
incurred in connection with providing distribution services.  Thus, payments
under a Plan may result in a profit to the Distributor.

     The Distributor may from time to time assist dealers by, among other
things, providing sales literature to, and holding educational programs for the
benefit of, dealers' registered representatives. Participation of registered
representatives in such informational programs may require the sale of minimum
dollar amounts of shares of the Funds of the Trust. The Distributor will also
provide additional promotional incentives to dealers in connection with sales of
shares of all classes of the Funds of the Trust. These incentives shall include
payment for travel expenses, including lodging (which may be at a luxury
resort), incurred in connection with trips taken by qualifying registered
representatives and members of their families within or outside the United
States. Incentive payments will be provided for out of the front end sales
charges and CDSCs retained by the Distributor, any applicable Distribution Plan
payments or the Distributor's other resources. Other than Distribution Plan
payments, the Fund does not bear distribution expenses. The staff of the
Securities and Exchange Commission has indicated that dealers who receive more
than 90% of the sales charge may be considered underwriters.

     Each of the Distributor and, with respect to shares purchased before
October 1, 1997, the Former Distributor currently pays a trail commission to
securities dealers, with respect to accounts that such dealers continue to
service for shares sold after April 1, 1994 as follows: Class A shares -- .25%
annually, commencing from the date the purchase order is accepted, for all Funds
(except the National Municipal Bond Fund, for which the trail commission is
 .15%, and the Money Market Fund, for which no trail commission is paid); Class B
shares -- .25% annually, for all Funds (except the National Municipal Bond Fund,
for which the trail commission is .15%, and the Money Market Fund, for which no
trail commission is paid); and Class C shares -- 1.0% annually, for all Funds
other than the Investment Quality Bond, U.S. Government Securities, National
Municipal Bond and Money Market Funds and .90% annually, for the Investment
Quality Bond, U.S. Government Securities and National Municipal Bond Fund (no
trail commission is paid on the Money Market Fund).

                                      -42-
<PAGE>
 
The trail commission payable following conversion of Class B and Class C shares
to Class A shares will be in accordance with the amounts paid for Class A
shares. For Class B and Class C shares sold on or after May 1, 1995, trail
commissions commence 13 months after purchase. For Class B and Class C shares
sold prior to May 1, 1995, trail commissions commence the date the purchase
order is accepted. Trail commissions for shares sold prior to April 1, 1994 will
be paid as noted below.

     In the case of Class B shares and Class C shares sold on or after May 1,
1995, the Distributor and, with respect to shares purchased before October 1,
1997, the Former Distributor, will advance to securities dealers the first year
service fee at a rate equal to 0.25% of the purchase price of such shares and,
as compensation therefor, the Distributor may retain the service fee paid by the
Fund with respect to such shares for the first year after purchase. In the case
of sales of Class B shares, the Distributor will pay each dealer a fee of 4% of
the amount of Class B shares purchased (0.25% is the advancement of the first
year service fee and the remainder is a commission or transaction fee). No
commission or transaction fee is paid for sales of shares of Class B of the
Money Market Fund. In the case of sales of Class C shares, the Distributor will
pay each securities dealer a fee of 1% (0.90% in the case of the Investment
Quality Bond, U.S. Government Securities and National Municipal Bond Fund of the
purchase price of Class C shares purchased through such securities dealer (0.25%
is the advancement of the first year service fee and the remainder is a
commission or transaction fee). No commission or transaction fee is paid for
sales of shares of Class C of the Money Market Fund.

     In adopting the Plans, the Trustees determined that the adoption of the
Plans is in the best interests of the Trust and its shareholders, that there is
a reasonable likelihood that the Plans will benefit the Trust and its
shareholders, and that the Plans are essential to, and an integral part of, the
Trust's program for financing the sale of shares of the various Funds of the
Trust to the public.

     The Distributor is a broker/dealer registered under the Securities Exchange
Act of 1934, as amended ("1934 Act") and a member of the NASD. The Distributor's
address is the same as that of the Trust.

     Neither a Plan nor any related agreements can take effect until approved by
a majority vote of both all the Trustees and those Trustees who are not
interested persons of the Trust and who have no direct or indirect financial
interest in the operation of a Plan or in any agreements related to it (the
"Qualified Trustees"), cast in person at a meeting called for the purpose of
voting on such Plan and the related agreements.

     The Plans will continue in effect only so long as their continuance is
specifically approved at least annually by the Trustees in the manner.  The
Trustees will receive quarterly and annual statements concerning distribution
and shareholder servicing expenditures.  In such statements, only expenditures
properly attributable to the sale or servicing of a particular class of shares
will be used to justify any distribution or servicing fee charged to that class.
Expenditures not related to the sale or servicing of a particular class will not
be presented to the Trustees to justify any fee attributable to that class.  The
statements, including the allocations upon which they are based, will be subject
to the review and approval of the Qualified Trustees in the exercise of their
fiduciary duty.  Each Plan may be terminated at any time with respect to any one
or more Funds by a majority vote of the Qualified Trustees or by vote of a
majority of the outstanding voting securities attributable to Class A, Class B
and Class C shares, as applicable, of such Portfolio or Funds.  If a Plan is
terminated by the Trustees or is otherwise discontinued with respect to one or
more Funds, no further payments would be made by the Trust in respect of the
Class A, Class B and Class C shares, as applicable, of such Fund or Funds under
that Plan.  A Plan may remain in effect with respect to Class A, Class B, Class
C or shares, as applicable, of a Fund even if it has been terminated with
respect to the Class A, Class B and Class C shares, as applicable, of one or
more other Funds.

     A Plan may not be amended with respect to any class of any Fund so as to
materially increase the amount of the fees payable thereunder unless the
amendment is approved by a vote of at least a majority of the outstanding voting
securities of such class of such Fund.  In addition, no material amendment to a
Plan may be made unless approved by the Trustees in the manner described above
for Trustee approval of the Plans.

                              PORTFOLIO BROKERAGE

     Pursuant to the Subadvisory Agreements, the Subadvisers are responsible for
placing all orders for the purchase and sale of portfolio securities of the
Fund, the portfolio transactions for which are the responsibility of the
Adviser.  The Subadvisers have no formula for the distribution of the Fund's
brokerage business, their intention being to place orders for the purchase and
sale of securities with the primary objective of obtaining the most favorable
overall results for the Fund.  The cost of securities transactions for each Fund
will consist primarily of brokerage commissions or dealer or underwriter
spreads.  Bonds and money market instruments are generally traded on a net basis
and do not normally involve either brokerage commissions or transfer taxes.

     Occasionally, securities may be purchased directly from the issuer.  For
securities traded primarily in the over-the-counter market, the Subadvisers
will, where possible, deal directly with dealers who make a market in the
securities unless better prices and execution are available elsewhere.  Such
dealers usually act as principals for their own account.

                                      -45-
<PAGE>
 
     The Subadvisers consider various factors in selecting brokers through which
orders for client accounts are executed. The Subadvisers' primary consideration
is the broker's ability to provide the best execution of the trade (including
both trade price and commission).  Assuming equal execution capabilities, the
Subadvisers also take other factors into account.

     In determining which brokers provide best execution, the Subadvisers look
primarily to the stock price quoted by the broker, and normally place orders
with the broker through which they can obtain the most favorable price.  If the
same price is available from more than one broker, a Subadviser's judgment as to
the following factors may influence the selection of a broker for a particular
trade: the execution, clearance and settlement capabilities of the brokers under
consideration; the nature of the security being traded; the difficulty of
execution; the size of the transaction; the desired timing of the trade; the
activity existing and expected in the market for the particular security;
confidentiality; the financial stability of the brokers under consideration;
actual or apparent operational problems of any broker under consideration; and
the negotiated commission rates available at the time of the trade.  The
Subadvisers may also consider the willingness of particular brokers to sell
shares of the Fund, subject to best execution and difficulty of execution.

     The Subadvisers also consider the nature and extent of research services
provided when they select brokers.  Assuming equal execution capabilities as
described above, the Subadvisers may direct commission business to brokers who
provide research services.  Such services include, but are not limited to:
analyses and reports concerning economic factors and trends, industries,
specific securities, portfolio strategy, and valuation and performance of
accounts; advice regarding critical factors supporting research recommendations
and special reports or information based on the specific requests of a
Subadviser's portfolio manager/analysts.  The Subadvisers may also from time to
time obtain research services prepared by third parties and provided by brokers
in exchange for a predetermined amount of commission business.  These services
include portfolio monitoring, analysis and performance measurement systems,
various economic forecasting and research services covering stocks and bonds,
research and trading conferences, and a source of information as to block
trading opportunities.  Some third party arrangements are cancelable at any time
while others require notice.  Such third party arrangements do not involve a
substantial amount of the Subadvisers' commission business on behalf of clients.

     In accordance with industry practice, commission rates are normally
determined through negotiations with brokers conducted by the Subadvisers'
traders.  These negotiations take into account industry norms for particular
transactions, the size and type of trades, the size and expertise of the
brokerage firm involved and the nature of brokerage and research services
provided, including special services in connection with a particular trade.
(Such special services could include, among other things, the assumption of
market risk in connection with a trade or series of trades or the facilitation
of trades in a thin or volatile market.)  Commission rates paid by the
Subadvisers in those cases may be higher than those charged by brokers for
execution of similar trades without the provision of research and/or special
services.

     No precise monetary value can be assigned to research and special execution
services furnished to the Subadvisers by brokers.  The Subadvisers will review
all research services and will determine if the amounts of commissions directed
to brokers are reasonable in relation to the value of the brokerage and research
services provided, viewed in terms of both particular transactions and the
Subadvisers' overall responsibilities with respect to the accounts over which
they exercise investment discretion.  Each Subadviser will maintain an internal
allocation procedure to identify those brokers who provide them with research
services and the amount of research services they provide, and will endeavor to
direct sufficient commissions to them to ensure the continued receipt of such
services as the Subadviser believes to be valuable.

     Research services furnished by brokers will generally be used in servicing
all of the Portfolios of the Fund advised by a Subadviser and any other accounts
over which that Subadviser exercises investment discretion, although not all of
such services may be used in connection with any particular Fund that paid
commissions to the brokers providing such services.

     The Subadvisers' practices in selecting brokers will be reviewed
periodically by the Trustees of the Fund.

     The Subadvisers and/or their affiliates currently manage portfolios and
accounts other than those of the Fund.  Although investment recommendations or
determinations for the Fund's Portfolios will be made by the Subadvisers
independently from the investment recommendations and determinations made by
them for any other portfolio or account or by the Subadvisers' affiliates for
the portfolios or accounts they manage, investments deemed appropriate for the
Fund's Portfolios by the Subadvisers may also be deemed appropriate by them or
affiliated advisers for other portfolios or accounts, so that the same security
may be purchased or sold at or about the same time for both the Fund's
Portfolios and such other portfolios or accounts.  In such circumstances, the
Subadvisers may determine that orders for the purchase or sale of the same
security for the Fund's Portfolios and one or more other portfolios or accounts
should be combined, in which event the transactions will be priced and allocated
in a manner deemed by the Subadvisers to be equitable and in the best interests
of the Fund's Portfolios and such other portfolios or accounts.  While in some
instances combined orders could adversely affect the price or volume of a
security, the Subadvisers and the Fund believe that its participation in such
transactions on balance will produce better overall results for the Fund.

                            MULTIPLE PRICING SYSTEM

     The Trust's Multiple Pricing System permits an investor to choose the
method of purchasing shares that is most beneficial given the amount of the
purchase and the length of time the investor expects to hold the shares.

     CLASS A SHARES.  Purchases of Class A shares of less than $1 million are
offered for sale at net asset value per share plus a front end sales charge of
up to 4.75% payable at the time of purchase (with the exception of Class A
shares of the Money Market Fund, which are offered without such a charge).
Purchases of Class A shares of $1 million or more are offered for sale at net
asset value without a front end sales charge but are subject to a contingent
deferred sales charge ("CDSC") of 1% of the dollar amount subject thereto
during the first year after purchase.  In addition, Class A shares are subject
to a distribution fee of up to .10% of their respective average annual net
assets and a service fee of up to .25% of their respective average annual net
assets (with the exception of Class A shares of the Money Market Fund, which
bear no such fees, and Class A shares of the National Municipal Bond Fund, which
are subject to a service fee of up to .15% of Class A average annual net assets
and are not subject to any distribution fee). Certain purchases of Class A
shares qualify for reduced front end sales charges.

     CLASS B SHARES.  Class B shares are offered for sale for purchases of
$250,000 or less. Class B shares are offered for sale at net asset value without
a front end sales charge, but are subject to a CDSC of 5% of the dollar amount
subject thereto during the first and second year after purchase, and declining
by 1% each year thereafter to 0% after the sixth year.  In addition, Class B
shares are subject to a distribution fee of up to .75% of their respective
average annual net assets and a service fee of up to .25% of their respective
average annual net assets (with the exception of Class B shares of the Money
Market Fund, which bear no such fees). The Class B shares enjoy the benefit of
permitting all of the investor's dollars to work from the time the investment is
made. The higher ongoing distribution and service fees paid by Class B shares
will cause such shares to have a higher expense ratio and to pay lower dividends
than Class A shares.  Class B shares purchased on or after October 1, 1997 will
automatically convert to Class A shares eight years after the end of the
calendar month in which the shareholder's order to purchase was accepted.

                                      -50-
<PAGE>
 
     CLASS C SHARES. Class C shares are offered for purchases of less than $1
million, at net asset value without a front end sales charge. Class C shares are
subject to a CDSC of 1% of the dollar amount subject thereto during the first
year after purchase. Class C shares are subject to a distribution fee of up to
 .75% of their respective average annual net assets and a service fee of up to
 .25% of their respective average annual net assets (with the exception of Class
C shares of the Money Market Fund, which bear no such fees). Class C shares,
like Class B shares, enjoy the benefit of permitting all of the investor's
dollars to work from the time the investment is made. The higher ongoing
distribution and service fees paid by Class C shares will cause such shares to
have a higher expense ratio and to pay lower dividends than Class A shares.
Class C shares will automatically convert to Class A shares ten years after the
end of the calendar month in which the shareholder's order to purchase was
accepted.

     CONTINGENT DEFERRED SALES CHARGE. Purchases of $1 million or more of Class
A shares are subject to a CDSC of 1% if redeemed within one year of purchase;
purchases of Class B shares are subject to a CDSC of 5% during the first and
second year after purchase declining by 1% each year thereafter to 0% after the
sixth year; and Class C shares are subject to a CDSC of 1% if redeemed within
one year of purchase. The applicable percentage is assessed on an amount equal
to the lesser of the original purchase price or the redemption price of the
shares redeemed. The CDSC is not applicable with respect to redemption of shares
of the Money Market Fund which were initially purchased as such and which were
never exchanged for shares of the same class of another Fund. However, in the
case of shares of the Money Market Fund which were obtained through an exchange,
such shares are subject to any applicable CDSC due at redemption. Similarly,
shares initially purchased as shares of the Money Market Fund which are
subsequently exchanged for shares of the same class of other Funds will be
subject to any applicable CDSC due at redemption.

     CONVERSION FEATURE. Class B shares (purchased on or after October 1, 1997)
and Class C shares will automatically convert to Class A shares eight years and
ten years, respectively, after the end of the calendar month in which the
shareholder's order to purchase was accepted and will thereafter no longer be
subject to the higher distribution and service fees. Such conversion will be on
the basis of the relative net asset values per share, without the imposition of
any sales charge, fee or other charge. (For Class B shares purchased prior to
October 1, 1997 such conversion will take place six years after purchase.) The
purpose of the conversion feature is to relieve the holders of Class B shares
and Class C shares from most of the burden of distribution-related expenses at
such time as when the shares have been outstanding for a duration sufficient for
the Distributor to have been substantially compensated for distribution-related
expenses incurred in connection with Class B shares or Class C shares, as the
case may be. Accordingly, Class B and Class C shares of the Money Market Fund do
not convert to Class A shares of the Money Market Fund at any time, as shares of
all classes of the Money Market Fund do not bear any distribution or service
fees. In addition, because Class B and Class C shares of the Money Market Fund
are not subject to any distribution or service fees, the applicable conversion
period is tolled for any period of time in which Class B or Class C shares are
held in that Fund. For example, if Class B shares of a Fund other than the Money
Market Fund are exchanged for Class B shares of the Money Market Fund two years
after purchase and are subsequently exchanged one year later for Class B shares
of a Fund other than the Money Market Fund, the one year of ownership in the
Money Market Fund does not count in the determination of the time of conversion
to Class A shares.

     For purposes of the conversion of Class B and Class C shares to Class A
shares, shares purchased through the reinvestment of dividends and distributions
paid on Class B shares or Class C shares, as the case may be, in a shareholder's
Fund account will be considered to be held in a separate sub-account. Each time
any Class B shares or Class C shares in the shareholder's Fund account (other
than those in the sub-account) convert to Class A shares, a pro rata portion of
the Class B shares or Class C shares, as the case may be, in the sub-account
will also convert to Class A shares.

     The Trust believes that the conversion of either Class B or Class C shares
to Class A shares does not constitute a taxable event under Federal income tax
law. If the Trust's view on this matter changes, it may suspend conversion of
Class B or Class C shares. In that event, which the Trust considers unlikely, no
further conversions of Class B or Class C shares would occur, and those shares
might continue to be subject to higher distribution and service fees for an
indefinite period that may extend beyond the period ending eight years or ten
years, respectively, after the end of the calendar month in which the
shareholder's order to purchase was accepted.

     FACTORS FOR CONSIDERATION. The Trust's Multiple Pricing System is designed
to provide investors with the option of choosing the class of shares which is
best suited to their individual circumstances and objectives. The different
sales charges, distribution and service fees and conversion features applicable
to each class, as outlined above, should all be taken into consideration by
investors in making the determination of which alternative is best suited for
them. To assist investors in evaluating the costs and benefits of purchasing
shares of each class, the information provided above under the caption "Fee
Table and

                                      -51-
<PAGE>
 
Example" sets forth the charges applicable to each class of shares and
illustrates an example of a hypothetical investment in each class of shares of
each Fund.

     There are several key distinctions among the classes of shares that
investors should understand and evaluate in comparing the options presented by
the Multiple Pricing System. Class A shares are subject to lower distribution
and service fees than are Class B and Class C shares, and, accordingly, pay
correspondingly higher dividends per share. However, because a front end sales
charge is deducted at the time of purchase for purchases of less than $1 million
of Class A shares, investors purchasing Class A shares do not have all of their
funds invested initially and, therefore, initially own fewer shares than they
would own if they had invested the identical sum in Class B shares or Class C
shares instead. In addition, Class C shares are subject to the same ongoing
distribution and service fees as Class B shares but are subject to a CDSC for a
shorter period of time (one year as opposed to six years) than Class B shares.
However, Class B shares convert to Class A shares, and lower ongoing
distribution and service fees, in a shorter time frame than do Class C shares.

     In light of these distinctions among the classes of shares, investors
should weigh such factors as (i) whether they qualify for a reduced front end
sales load for a purchase of Class A shares; (ii) whether, at the time of
purchase, they anticipate being subject to a CDSC upon redemption if they
purchase Class A shares (purchases of $1 million or more), Class B shares or
Class C shares; (iii) the differential in the relative amounts that would be
paid during the anticipated life of investments (which are made at the same time
and in the same amount) in each class which are attributable to (a) the front
end sales charge (for purchases of less than $1 million) and any applicable CDSC
(for purchases of $1 million or more) and accumulated distribution and service
fees payable with respect to Class A shares and (b) the accumulated distribution
and service fees (and any applicable CDSC) payable with respect to Class B
shares or Class C shares prior to their conversion to Class A shares; and (iv)
to what extent the differential referred to above might be offset by the higher
yield of Class A shares. Investors should also weigh these considerations
against the fact that the higher continued distribution and service fees
associated with Class B shares and Class C shares will be offset to the extent
any return is realized on the additional funds initially invested and that there
can be no assurance as to the return, if any, which will be realized on such
additional funds. Class A shares are, in general, the most beneficial for the
investor who qualifies for reduced front end sales charges. For this reason,
Class B shares are not offered for purchases in excess of $250,000 and Class C
shares are not offered for purchases of $1 million or more. Investors should
consult their investment representative for assistance in evaluating the
relative benefits of the different classes of shares.

     Dividends paid by a Fund with respect to each class of shares will be
calculated in substantially the same manner at the same time on the same day,
except that distribution and service fees and any other costs specifically
attributable to a particular class of shares will be borne solely by the
applicable class. Shares of a Fund may be exchanged for shares of the same class
of any other Fund, but not for shares of other classes of any Fund.

     Taxable dividends from any source, other than long-term capital gains,
distributed to individuals by mutual funds are currently taxed at federal income
tax rates of up to 39.6%, and the effective tax rate may be higher due to
limitations at higher income levels on allowable deductions and exemptions. 
Long-term capital gains distributed to individuals by mutual funds are currently
taxed at a federal income tax rate of 20%. Taxable dividends from any source,
including long-term capital gains, distributed to corporations by mutual funds
are currently taxed at federal income tax rates of up to 35%. Additionally,
state taxes on mutual fund distributions reduce after-tax returns.

                                 CAPITAL STOCK

     All shares of beneficial interest, $.001 par value per share, of each Fund
have equal voting rights (except as described below with respect to matters
specifically affecting a class of shares) and have no preemptive or conversion
rights. The Trust's Declaration of Trust permits the issuance of multiple
classes of shares pursuant to the Multiple Pricing System. Shares of each class
of a Fund represent interests in that Fund in proportion to each share's net
asset value. The per share net asset value of each class of shares in a Fund is
calculated separately and may differ as between classes as a result of the
differences in distribution and service fees payable by the classes and the
allocation of certain incremental class-specific expenses to the appropriate
class to which such expenses apply.

     All shares of the Trust have equal voting rights and will be voted in the
aggregate, and not by series (Fund) or class, except where voting by series or
class is required by law or where the matter involved affects only one series or
class (for example, matters pertaining to the plan of distribution relating to
Class A shares will only be voted on by Class A shares). Matters required

                                      -52-
<PAGE>
 
by the 1940 Act to be voted upon by each affected series include changes to (i)
the Advisory Agreement, (ii) a Subadvisory Agreement and (iii) fundamental
investment objectives and policies.

     The Trust is not generally required to hold annual meetings of
shareholders. However, the Trustees may call special meetings of shareholders
for action by shareholder vote as may be requested in writing by the holders of
25% or more of the outstanding shares of the Trust (10% in the case of a meeting
requested for the purpose of removing a Trustee) or as may be required by
applicable laws. Shareholders seeking to call a meeting for the purpose of
removing a Trustee will be assisted by the Trust in communicating with other
shareholders, provided the shareholders seeking to call a meeting are at least
ten in number, have been shareholders for at least six months and hold in the
aggregate at least one percent of the outstanding shares or shares having a
value of at least $25,000, whichever is less. Also, Trustees may be removed by
action of the holders of two-thirds or more of the outstanding shares of the
Fund. The Trustees are authorized to create additional series and classes of
shares at any time without approval by shareholders.

     Under Massachusetts law, shareholders of a business trust may, in certain
circumstances, be held personally liable as partners for the obligations of the
Trust. However, the Trust's Declaration of Trust contains an express disclaimer
of shareholder liability for acts or obligations of each Fund of the Trust and
requires that notice of such disclaimer be given in each instrument entered into
or executed by the Trust. The Declaration of Trust also provides for
indemnification out of a Fund's property for any shareholder of such Fund held
personally liable for any of the Fund's obligations. Thus, the risk of a
shareholder being personally liable as a partner for obligations of a Fund is
limited to the unlikely circumstance in which the Fund itself would be unable to
meet its obligations.

                       PURCHASE, REDEMPTION AND PRICING

     Certain Qualified Purchasers. No front end sales charge or CDSC is
applicable to any sale of Class A shares to a Trustee or officer of the Fund, or
to the immediate families (i.e., the spouse, children, mother or father) of such
persons, or any full-time employee or registered representative of
broker/dealers having Dealer Agreements with the Distributor ("Selling
Broker") and their immediate families (or any trust, pension, profit sharing or
other benefit plan for the benefit of such persons), or any full-time employee
of a bank, savings and loan, credit union or other financial institution that
utilizes a Selling Broker to clear purchases of Fund shares, and their immediate
families. In addition, no front end sales charge or CDSC is applicable on any
sale to CypressTree or any of its affiliates, the Subadvisers or Wood Logan, or
to a director, officer, full-time employee or sales representative of
CypressTree or any of its affiliates, the Subadvisers or any of their affiliates
or of Wood Logan, or to the immediate families of such persons, or any trust,
pension, profit-sharing or other benefit plan for the benefit of such persons.

     No front end sales charge or CDSC on Class A shares is applicable to
continuing purchase payments made in connection with Code Section 401 qualified
plans that were invested in the Fund prior to April 1, 1994.

     A qualified retirement plan that is currently a shareholder of the Fund may
make additional purchases of Class A shares at net asset value (i.e., without
the imposition of a front end sales load or CDSC). A commission or transaction
fee of 1.00% will be paid by the Distributor to broker-dealers, banks and other
financial service firms subject to a chargeback to the firm for redemptions made
within one year from the date of purchase.

     Shares may be sold at net asset value to certain categories of investors,
including to shareholders of other investment companies, who invest in North
American Funds in response to certain promotional activities.

     Class A shares may be purchased at net asset value by certain broker-
dealers and other financial institutions which have entered into an agreement
with the Distributor, which includes a requirement that such shares be sold for
the benefit of clients participating in a "wrap account" or a similar account
program under which such clients pay a fee to such broker-dealer or other
financial institution. Class A shares may also be purchased at net asset value
by registered investment advisers for the benefit of client accounts if the
adviser charges a fee (other than brokerage commissions) for his services.

                                      -53-

DETERMINATION OF NET ASSET VALUE

     The following supplements the discussion set forth in the Prospectus. The
assets belonging to each class of shares of a Fund will, in each case, be
invested together in a single portfolio. The net asset value of each class will
be determined separately by subtracting the expenses and liabilities allocated
to that class from the assets belonging to that class.

     The Trustees have authorized the Funds to value certain debt securities by
reference to valuations obtained from pricing services which take into account
appropriate factors such as institution-size trading in similar groups of
securities, yield, quality, coupon rate, maturity, type of issue, trading
characteristics and other market data in determining valuations of such
securities, without extensive reliance upon quoted prices, since such valuations
are believed by the Trustees to more accurately reflect the fair value of such
securities.

     Securities held by each of the Funds other than the Money Market Fund,
except for money market instruments with remaining maturities of 60 days or
less, are valued as follows: securities which are traded on stock exchanges are
valued at the last sales price as of the close of the Exchange, or lacking any
sales, at the closing bid prices. Securities traded only in the "over-the-
counter" market are valued at the last bid prices quoted by brokers that make
markets in the securities at the close of trading on the Exchange. Securities
and assets for which market quotations are not readily available or not obtained
from a pricing service are valued at fair value as determined in good faith by
the Trustees, although the actual calculations may be made by persons acting
pursuant to the direction of the Trustees. If approved by the Trustees, the Fund
may make use of a pricing service or services in determining the net asset value
of the classes of the Funds.

     All instruments held by the Money Market Fund and money market instruments
with a remaining maturity of 60 days or less held by the other Funds will be
valued on an amortized cost basis. Under this method of valuation, the
instrument is initially valued at cost (or in the case of instruments initially
valued at market value, at the market value on the day before its remaining
maturity is such that it qualifies for amortized cost valuation); thereafter,
the Fund assumes a constant proportionate amortization in value until maturity
of any discount or premium, regardless of the impact of fluctuating interest
rates on the market value of the instrument. While this method provides
certainty in valuation, it may result in periods during which value, as
determined by amortized cost, is higher or lower than the price that would be
received upon sale of the instrument.

     The Money Market Fund uses the amortized cost valuation method in reliance
upon Rule 2a-7 under the 1940 Act. As required by Rule 2a-7, the Money Market
Fund will maintain a dollar weighted average maturity of 90 days or less. The
Trustees have established procedures designed to stabilize, to the extent
reasonably possible, the Money Market Fund's price per share (for each class) as
computed for the purposes of sales and redemptions at $1.00.

REDEMPTION IN KIND

     Although it is each of the Funds' present policy to make payment of
redemption proceeds in cash, if the Trustees determine it appropriate,
redemption proceeds may be paid in whole or in part by a distribution in kind of
marketable securities held by that Fund subject to the limitation that each Fund
is obligated to redeem shares solely in cash up to the lesser of $250,000 or 1%
of the net asset value of the Fund during any 90-day period for any one account.
If a redemption in kind is made, a shareholder might be required to bear
transaction costs, including brokerage commissions, to dispose of such
securities. The Fund will endeavor to only distribute securities for which there
is an active trading market.

REPURCHASE OF SHARES

     The Distributor is authorized to repurchase Fund shares through certain
securities dealers who have entered into dealer agreements with the Distributor.
The offer to repurchase may be suspended by the Distributor at any time. Dealers
may charge for their services in connection with a repurchase, but neither the
Fund nor the Distributor makes any such charge. Repurchase arrangements differ
from redemptions in that the dealer buys the shares as principal from his
customer in lieu of tendering shares to the Fund for redemption as agent for the
customer. The proceeds to the shareholder will be the net asset value of the
shares repurchased as next determined after receipt of the repurchase order by
the dealer. By a repurchase, the customer should be able to receive the sale
proceeds from the dealer more quickly. Shareholders should contact their dealers
for further information as to how to effect a repurchase and the dealer's
charges applicable thereto.

PAYMENT FOR THE SHARES PRESENTED

                                      -54-
<PAGE>
 
     Payment for shares presented for redemption will be based on the net asset
value of the applicable class of the applicable Fund next computed after a
request is received in proper form at the Transfer Agent's office. Certain
redemptions of Class A, B and C shares may be subject to a CDSC, which will be
deducted from the redemption proceeds. Payment proceeds will be mailed within
seven days following receipt of all required documents. However, payment may be
postponed or the right of redemption suspended (i) for any period during which
the New York Stock Exchange is closed for other than customary weekend and
holiday closing or during which trading on the New York Stock Exchange is
restricted; (ii) for any period during which an emergency exists as a result of
which disposal by the Fund of securities owned by it is not reasonably
practicable or it is not reasonably practicable for the Fund fairly to determine
the value of its net assets; or (iii) for such other periods as the Commission
may by order permit for the protection of shareholders, provided that applicable
rules and regulations of the Commission shall govern as to whether the
conditions described in (i) and (ii) exist. Payment of proceeds may also be
delayed if the shares to be redeemed or repurchased were purchased by check and
that check has not cleared (which may be up to 15 days or more).

CUSTODIAN AND TRANSFER AND DIVIDEND DISBURSING AGENTS

     State Street Bank and Trust Company ("State Street"), 225 Franklin
Street, Boston, Massachusetts 02110, currently acts as Custodian of all the
Fund's assets, as well as the bookkeeping, transfer and dividend disbursing
agent for all of the Funds of the Fund. State Street has selected various banks
and trust companies in foreign countries to maintain custody of certain foreign
securities. State Street is authorized to use the facilities of the Depository
Trust Company, the Participants Trust Company and the book-entry system of the
Federal Reserve Banks.


                            PERFORMANCE INFORMATION

     From time to time the Trust may advertise certain information about the
performance of all classes of one or more of the Funds. Such performance
information may include time periods prior to the establishment of the multi-
class distribution system. Information about performance of a class of shares of
a Fund is not intended to indicate future performance. The Trust's annual report
to shareholders, which is available without charge upon request, contains
further discussions of Fund performance.

     The Funds may advertise the yield and/or total return performance for all
classes of one or more of the Funds in accordance with the rules of the
Commission. The National Municipal Bond Fund may also present from time to time
yield, tax-equivalent yield and standardized and nonstandardized total return in
advertisements. When yield is used in sales literature, the total return figures
will also be included. The Commission has issued rules setting forth the uniform
calculation of both yield and total return, but shareholders' actual experience
may be more or less than the figures produced by these formulas.

     Each Fund may include the total return for all classes of shares in
advertisements or other written material. Each such piece will include at least
the average annual total return quotations for one year, five years, ten years
(if available) and/or from the commencement of operations. Total return is
measured by comparing the value of an investment at the beginning of the
relevant period to the redemption value of the investment at the end of the
period; the calculation assumes the initial investment is made at the current
maximum net offering price, assumes immediate reinvestment of any dividends or
capital gains distributions and adjusts for the current maximum sales charge of
4.75% for Class A shares and the applicable CDSC imposed on a redemption of
Class B shares or Class C shares held for the period indicated. Yield and total
return are calculated separately for each class of a Fund.

     Each of the Funds may advertise yield for all classes, accompanied by total
return. The yield will be computed by dividing the net investment income per
share earned during a recent one month period (after deducting expenses net of
reimbursements applicable to each class) by the maximum offering price
(including the maximum front end sales charge or applicable CDSC) on the last
day of the period, and annualizing the result (assuming compounding of interest)
in order to arrive at annual percentage rate. The National Municipal Bond Fund
may also present from time to time the tax-equivalent yield of all classes. The
tax-equivalent yield is calculated by determining the portion of yield which is
tax-exempt and calculating the equivalent taxable yield and adding to such
amount any fully taxable yield.

     The Money Market Fund may advertise yield and effective yield for all
classes. The yield is based upon the income earned by the Fund over a seven-day
period and is then annualized, i.e., the income earned in the period is assumed
to be earned every seven days over a 365 day period and is stated as a
percentage of the investment. Effective yield is calculated similarly, but when
annualized the income earned by the investment is assumed to be reinvested
weekly in shares of the same class and thus compounded in the course of a 365
day period. The effective yield will be higher than the yield because of the
compounding effect of this assumed reinvestment.

                                      -55-

     All performance information may be compared with data published by Lipper
Analytical Services, Inc. or to unmanaged indices of performance, including, but
not limited to, the Dow Jones Industrial Average, S&P 500, S&P MidCap 400 Index,
Value Line Composite, Lehman Brothers Bond, Government Corporate, Municipal,
Corporate and Aggregate Indices, Merrill Lynch Government & Agency and
Intermediate Agency Indices, the Salomon Brothers Non-Dollar WGBI 10 Index,
Russell 2000 Growth Index, the EAFE Index or the Morgan Stanley Capital
International World Index. In addition, during certain time periods the yield
and total return of a class and/or a Fund may be affected by expense waivers
and/or expense reimbursements. When so affected, the yield and total return
figures will be accompanied by a statement regarding such waiver and/or
reimbursement. While performance information may be helpful in evaluating
whether a Fund may be fulfilling its objective, past performance should not be
regarded as representative of future results. Yields and net asset values will
fluctuate with market conditions and the value of shares redeemed may be more or
less than their cost. The Money Market Fund operates under procedures designed
to stabilize the net asset value of all classes at $1.00 per share. A Fund will
include performance data for each class of a Fund in any advertisement or
information including performance data of such Fund. The Fund may also utilize
performance information in hypothetical illustrations provided in narrative
form.

     A Fund may advertise its yield and/or total return performance for all
classes of shares of one or more of the Funds, calculated in accordance with the
rules of the Commission. Such performance information may include time periods
prior to the implementation of the Multiple Pricing System on April 1, 1994, and
will be calculated as described below. For purposes of quoting and comparing the
performance of the classes of the Funds to that of other mutual funds and to
stock or other relevant indices in advertisements or in reports to shareholders,
performance will be stated in terms of total return and yield. Both "total
return" and "yield" figures are based on historical performance, show the
performance of a hypothetical investment and are not intended to indicate future
performance.

     Under the rules of the Commission, funds advertising performance must
include total return quotes, "T" below, calculated according to the following
formula:

P(1 + T)/n/  = ERV

Where:

                P =   a hypothetical initial payment of $1,000

                T =   average annual total return

                n =   number of years (1, 5 or 10)

               ERV =  ending redeemable value of a hypothetical $1,000 payment
                      made at the beginning of the "n" year period (or
                      fractional portion thereof) at the end of such period.

     The average annual total return will be calculated under the foregoing
formula and the time periods used in advertising will be based on rolling
calendar quarters, updated to the last day of the most recent quarter prior to
submission of the advertising for publication, and will cover one, five, and ten
year periods (if available) plus the time period since the effective date of the
Fund's registration statement. When the period since inception for a Fund is
less than one year, the total return quoted will be the aggregate return for the
period. In calculating the ending redeemable value, for Class A shares, the
current maximum front end sales charge of 4.75% (as a percentage of the offering
price) is deducted from the initial $1,000 payment, and for Class B shares, the
applicable CDSC imposed on a redemption of shares held for the period is
deducted. The formula also assumes that all dividends and distributions have
been reinvested at net asset value as described in the Prospectus on the
reinvestment dates during the period. Total return, or "T" in the formula above,
is computed by finding the average annual compounded rates of return over the 1,
5 and 10 year periods (or fractional portions thereof) that would equate the
initial amount invested to the ending redeemable value. Any sales charges that
might in the future be made applicable to reinvestments would be included as
would any recurring account charges that might be imposed by the Trust.

     The figures shown in the table below are, for all classes, restated to
reflect front end sales charges and CDSCs currently payable by each class of
shares under the Multiple Pricing System (as described above), and (for all of
the tables presented below) are based on the distribution and service fees and
other expenses actually paid by each Fund for the periods presented, rather than
the distribution and service fees and other expenses currently payable by each
class of shares under the Multiple Pricing System, which in certain cases are
different. Until April 1, 1994, each Fund paid distribution and service fees
under the Prior Plan.

     The following tables set forth the average annual total returns for each
class of shares of each Fund for certain

     The Funds have been and still are subject to certain fee reimbursements.
Absent such reimbursement, the returns shown above would be lower.

     The performance data quoted represents past performance; investment returns
and principal value of an investment will fluctuate so that an investor's
shares, when redeemed, may be worth more or less than their original cost. On
July 10, 1992, the former Aggressive, Moderate and Conservative Asset Allocation
Trusts were reorganized into the Balanced Fund. The Balanced Fund's investment
objectives, policies and restrictions are identical to the old Moderate Asset
Allocation Trust. The performance figures shown above for the Balanced Fund
therefore are based on the past performance of the former Moderate Asset
Allocation Trust for the period prior to July 10, 1992.

     A Fund's yield is a way of showing the rate of income the Fund earns on its
investments as a percentage of the Fund's share price. Under the rules of the
Commission, yield must be calculated according to the following formula:

                 a-b    6
        YIELD     = 2[(--- + 1)  - 1]
                  cd
Where:
                  a = dividends and interest earned during the period.

                  b = expenses accrued for the period (net of
                    reimbursement).

                  c = the average daily number of shares outstanding
                    during the period that were entitled to receive
                    dividends.

                  d = the maximum offering price per share on the last
                    day of the period.

Yields for the classes of the Funds used in advertising are computed by dividing
the class of the Fund's interest and dividend income for a given 30 day period,
net of expenses, by the average number of shares entitled to receive
distributions during the period, dividing this figure by the offering price
(including the applicable front end sales charge or CDSC) at the end of the
period and annualizing the result (assuming compounding of income) in order to
arrive at an annual percentage rate. Income is calculated for purposes of yield
quotations in accordance with standardized methods applicable to all stock and
bond mutual funds. Dividends from equity investments are treated as if they were
accrued on a daily basis, solely for the purposes of yield

                                      -58-
<PAGE>
 
calculations. In general, interest income is reduced with respect to bonds
trading at a premium over their par value by subtracting a portion of the
premium from income on a daily basis, and is increased with respect to bonds
trading at a discount by adding a portion of the discount to daily income.
Capital gains and losses generally are excluded from the calculation. Income
calculated for the purposes of calculating the Fund's yield differs from income
as determined for other accounting purposes. Because of the different accounting
methods used, and because of the compounding assumed in yield calculations, the
yield quoted for a class of a Fund may differ from the rate of distributions
paid over the same period or the rate of income reported in the Fund's financial
statements. The yields for Classes A, B and C of the Investment Quality Bond
Fund for the thirty day period ended October 31, 1998 were 5.43% and 5.04%,
5.04% respectively. The yields for Classes A, B and C of the U.S. Government
Securities Fund for the thirty day period ended October 31, 1998 were 4.31%,
3.87% and 3.87%, respectively. The yields for Classes A, B and C of the
Strategic Income Fund for the thirty day period ended October 31, 1998 were
6.78%, 6.46% and 6.46%, respectively.

     Yield quotations for the Investment Quality Bond and U.S. Government
Securities and Strategic Income Funds will reflect the fact that such Funds will
have paid no advisory fees during certain periods of their operations.
Therefore, the yield for those Funds encompassing the periods during which no
advisory fees were paid will be higher than the yields the Funds would have
realized had the suspension of advisory fees not been in effect.

     The yields for Classes A, B and C of the National Municipal Bond Fund for
the thirty day period ended October 31, 1998 were 3.65%, 2.98% and 2.98%,
respectively. With respect to the National Municipal Bond Fund, tax-equivalent
yields are computed by dividing that portion of yield that is tax-exempt by one,
minus a stated income tax rate and adding the quotient to that portion, if any,
of the yield that is not tax-exempt.
                     ---

     Yields for the Money Market Fund will be computed on the basis of seven-day
periods, and such quotations will be in lieu of total return quotations for the
one, five and ten year periods described above. Yields will be computed by
dividing the net change, exclusive of capital changes, in the value of a
hypothetical account having a balance of one share at the beginning of the 
seven-day period by the value of the account at the beginning of the period and
multiplying the return so determined ("base period return") by 365/7. Effective
yields will be computed by compounding the base period return in accordance with
the following formula:

      Effective yield = [(Base period return +1)365/7] - 1

     For the seven-day period ended October 31, 1998, yields for Classes A, B
and C of the Money Market Fund were 4.55%, 4.55% and 4.55%, respectively. For
the seven-day period ended October 31, 1997, the effective yields for Classes A,
B and C of the Money Market Fund were 5.15%, 5.15% and 5.15%, respectively.

     Yield and total return are calculated separately for each class of shares
of a Fund. As discussed above, these calculations adjust for the different front
end sales charges and CDSCs currently payable with respect to each class, and
are based on distribution and service fees and other expenses actually paid by
each Fund for the periods presented.

     The Trust may also from time to time include in advertising a total
aggregate return figure or an average annual total return figure that is not
calculated according to the formula set forth above in order to compare
performance more accurately with other measures of investment return. Each class
of a Fund may quote an aggregate total return figure in comparing total return
with data published by Lipper Analytical Services, Inc. or with the performance
of various indices including, but not limited to, the Dow Jones Industrial
Average, the Standard & Poor's 500 Stock Index, the Value Line Composite Index,
the Lehman Brothers Bond, Government Corporate, Corporate and Aggregate Indices,
Merrill Lynch Government & Agency Index, Merrill Lynch Intermediate Agency
Index, Morgan Stanley Capital International Europe, Australia, Far East Index or
the Morgan Stanley Capital International World Index. For such purposes,
aggregate total return is calculated for the specified periods of time by
assuming the investment of $1,000 in shares of a class of a Fund and assuming
the reinvestment of each dividend or other distribution at net asset value on
the reinvestment date. Percentage increases are determined by subtracting the
initial value of the investment from the ending value and by dividing the
remainder by the beginning value. The Trust does not, for these purposes, deduct
from the initial value invested any amount representing front end sales charges
or CDSCs applicable to a class. To calculate its average annual total return,
the aggregate return is then annualized according to the Commission's formula
for total return quotes, outlined above. When the period since inception is less
than one year, the total return quoted will be the aggregate return for the
period. The Trust will, however, disclose the maximum front end sales charge or
CDSC applicable to each class and will also disclose that the performance data
does not reflect sales charges and that the inclusion of sales charges would
reduce

                                      -59-
<PAGE>
 
the performance quoted. Such alternative total return information will be given
no greater prominence in such advertising than the information prescribed under
Commission rules and all advertisements containing performance data will include
a legend disclosing that such performance data represent past performance and
that the investment return and principal value of an investment will fluctuate
so that an investor's shares, when redeemed, may be worth more or less than
their original cost. The Trust may also advertise the performance rankings
assigned certain Funds (or classes thereof) or their investment subadvisers by
various publications and statistical services, including but not limited to SEI,
Lipper Analytical Services, Inc.'s Mutual Fund Performance Analysis, Intersec
Research Survey of Non-U.S. Equity Fund Returns, Frank Russell International
Universe, and any other data which may be presented from time to time by such
analysis as Dow Jones, Morningstar, Chase Investment Performance, Wilson
Associates, Stanger, CDA Investment Technology, the Consumer Price Index
("CPI"), The Bank Rate Monitor National Index, IBC/Donaghue's Average/U.S.
Government and Agency, or as they appear in various publications including but
not limited to The Wall Street Journal, Forbes, Barrons, Fortune, Money
Magazine, The New York Times, Financial World and Financial Services Week.

     Calculated in the manner set forth immediately above, the average annual
total returns for each class of shares of each Fund for the one and five year
periods ended October 31, 1998 and since inception to October 31, 1998 are as
follows:

* Certain taxpayers may, to the extent such taxpayers itemize deductions or
claim personal exemptions, be subject to a higher marginal rate. In addition,
the tax rate on net capital gains of individuals may not exceed 28%.

**Taxable Income amounts apply for taxable years beginning in 1996. The amounts
are indexed annually for inflation.

                                     TAXES

     The following information supplements the disclosure contained in the
Prospectus under the heading "Taxes." No attempt is made to present a detailed
explanation of all federal, state, local and foreign tax concerns, and the
discussion set forth here and in the Prospectus do not constitute tax advice.
Investors are urged to consult their own tax advisers with specific questions
relating to federal, state, local and foreign taxes.

     Each Fund intends to qualify as a regulated investment company (a "RIC")
under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code")
and to continue to so qualify. Qualification as a RIC requires, among other
things, that each Fund: (a) derive at least 90% of its gross income in each
taxable year from dividends, interest, payments with respect to securities loans
and gains from the sale or other disposition of stock, securities or foreign
currencies, or other income (including gains from options, futures or forward
contracts) derived with respect to its business of investing in such stocks or
securities (b) diversify its holdings so that, at the end of each quarter of
each taxable year, (i) at least 50% of the total value of a Fund's assets is
represented by cash, cash items, U.S. government securities, securities of other
regulated investment companies and other securities with such other securities
limited, in respect of any issuer, to an amount not greater than 5% of the total
value of a Fund's assets and 10% of the outstanding voting securities of such
issuer, and (ii) not more than 25% of the value of its assets is invested in the
securities (other than U.S. government securities or the securities of other
regulated investment companies) of any one issuer.

     As a RIC, a Fund will not be subject to federal income tax on its net
investment income (i.e., its investment company taxable income, as that term is
defined in the Code, determined without regard to the deduction for dividends
paid) and "net capital gains" (the excess of a Fund's net long-term capital
gains over net short-term capital Losses), if any, that it distributes in each
taxable year to its shareholders, provided that it distributes with respect to
each taxable year at least 90% of the sum of its net investment income, its net
tax-exempt income and the excess, if any, of net short term capital gains over
net long-term capital losses for such year. Each Fund expects to designate
amounts retained as undistributed net capital gains in a notice to its
shareholders who (i) will be required to include in income for United States
federal income tax purposes, as long-term capital gains, their proportionate
shares of the undistributed amount, (ii) will be entitled to credit their
proportionate shares of the 35% tax paid by a Fund on the undistributed amount
against their federal income tax liabilities and to claim refunds to the extent
such 

                                      -62-
<PAGE>
 
credits exceed their liabilities and (iii) will be entitled to increase their
tax basis, for federal income tax purposes, in their shares by an amount equal
to 65% of the amount of undistributed net capital gains included in the
shareholder's income.

     A Fund will be subject to a nondeductible 4% excise tax on the amount by
which the aggregate income it distributes in any calendar year is less than the
sum of: (a) 98% of a Fund's ordinary income for such calendar year; (b) 98% of
its capital gain net income (the excess of capital gains over capital losses,
both long- and short-term) for the one-year period ending on October 31 of each
year; and (c) 100% of the undistributed ordinary income and gains from prior
years. For this purpose, any income or gains retained by a Fund subject to
corporate income tax will be considered to have been distributed by year-end.
Each Fund expects to distribute substantially all of its net income and gain,
and, assuming that it does so, it will not be subject to this excise tax.

     Pay-in-kind Bonds, Zero Coupon Bonds and Discount Obligations. Certain
Funds may make investments that produce income that is not matched by a
corresponding cash distribution to the Fund, such as investments in pay-in-kind
bonds or in discount obligations such as zero coupon securities, certain
sovereign debt securities and stripped mortgage securities having original issue
discount or market discount (if a Fund elects to accrue the market discount on a
current basis with respect to such instruments). Such income would be treated as
income earned by the Fund and therefore would be subject to the distribution
requirements of the Code. Because such income may not be matched by a
corresponding cash distribution to the Fund, the Fund may be required to borrow
money or dispose of other securities to be able to make distributions to its
investors. For example, pursuant to a provision of the Code governing the
treatment of securities such as the stripped mortgage securities described in
this Statement of Additional Information, a principal-only ("PO") class will be
treated as having been issued with original issue discount and, consequently,
will result in income to the Fund without a corresponding distribution of cash
to the Fund. A portion of the amount received on a PO class will constitute a
return of the Fund's investment and as such will not be income.

     Special Rules for Certain Foreign Currency Transactions.

     Investments in Passive Foreign Investment Companies. Investment by a Fund
in certain "passive foreign investment companies" could subject the Fund to a
U.S. federal income tax (including interest charges) on distributions received
from the company or on proceeds received from the disposition of shares in the
company, which tax cannot be eliminated by making distributions to Fund
shareholders. However, the Fund may elect to treat a passive foreign investment
company as a "qualified electing fund," in which case the Fund will be required
to include its share of the company's income and net capital gain annually,
regardless of whether it receives any distribution from the company. The Fund
also may make an election to mark the gains (and to a limited extent losses) in
such holdings "to the market" as though it had sold and repurchased its holdings
in those PFICs on the last day of the Fund's taxable year. Such gains and losses
are treated as ordinary income and loss. The qualified electing fund and 
mark-to-market elections may have the effect of accelerating the recognition of
income (without the receipt of cash) and increase the amount required to be
distributed for the Fund to avoid taxation. Making either of these elections
therefore may require a Fund to liquidate other investments (including when it
is not advantageous to do so) to meet its distribution requirement, which also
may accelerate the recognition of gain and affect a Fund's total return.

     Foreign Withholding Taxes. Certain dividends and interest received by a
Fund may be subject to foreign withholding taxes. If more than 50% in value of a
Fund's total assets at the close of any taxable year consists of stocks or
securities of foreign corporations, the Fund may elect to treat any foreign
income taxes paid by it as paid by its shareholders. If eligible, the Fund(s)
intend to make this election. If a Fund makes this election, its shareholders
will be required to include in income their respective pro rata portions of
foreign income taxes paid by the Fund(s) and, if they itemize their deductions,
will be entitled to deduct such respective pro rata portions in computing their
taxable income or, alternatively, to claim foreign tax credits (subject to the
limitations discussed below). A shareholder's ability to claim a foreign tax
credit or deduction in respect of eligible foreign taxes paid by a Fund may be
subject to certain limitations imposed by the Code, as a result of which a
shareholder may not get a full credit or deduction for the amount of such taxes
(including a holding period requirement). Each year that a Fund makes this
election, it will report to its shareholders the amount per share of foreign
income taxes it has elected to have treated as paid by its shareholders.

     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 RIC may pass through to its shareholders state and
local income tax exemptions available to direct owners of certain types of U.S.
government securities. For residents of these states, distributions derived from
a Fund's interest income from these securities should be free from state and
local income taxes. Certain states, however, do not permit RICs to pass through
to their shareholders the state and local income tax exemptions available to
direct owners of certain types of U.S. government securities unless the RIC owns
a required amount of those securities. The Trust believes that the non-pass
through provisions in these states are questionable. Shareholder's dividends
attributable to a Fund's income from repurchase agreement involving U.S.
government securities generally are subject to state and local income taxes,
although states and regulations vary in their treatment of such income. The
exemption from state and local income taxes does not preclude states

                                      -63-
<PAGE>
 
from asserting other taxes on the ownership of U.S. government securities. To
the extent that a Fund invests to a substantial degree in U.S. government
securities that are subject to favorable state and local tax treatment,
shareholders of such a Fund will be notified as to the extent to which
distributions from the Fund are attributable to interest on such securities.

NATIONAL MUNICIPAL BOND FUND

     The National Municipal Bond Fund intends to qualify to pay "exempt-interest
dividends," as that term is defined in the Code, by holding at the end of each
quarter of its taxable year at least 50% of the value of its total assets in the
form of municipal obligations described in section 103(a) of the Code. Because
the National Municipal Bond Fund will primarily invest in municipal obligations,
dividends from the Fund will generally be exempt from regular federal income tax
in the hands of shareholders subject to the possible application of the
alternative minimum tax. Further, gain from a sale of redemption of shares of
the National Municipal Bond Fund will be taxable to shareholders as capital gain
even though the increase in value of such shares is attributable to tax-exempt
income. Thus, it will normally be advantageous for the National Municipal Bond
Fund to declare exempt-interest dividends frequently.

     Federal tax law imposes an alternative minimum tax with respect to both
corporations and individuals based on certain items of tax preference. Interest
on certain municipal obligations, such as bonds issued to make loans for housing
purposes or to private entities (but not to certain tax-exempt organizations
such as universities and non-profit hospitals) is included as an item of tax
preference in determining the amount of a taxpayer's alternative minimum taxable
income. To the extent that the Fund receives income from municipal obligations
treated as a tax preference item for purposes of the alternative minimum tax, a
portion of the dividends paid by it, although otherwise exempt from federal
income tax, will be taxable to shareholders to the extent that their tax
liability will be determined under the alternative minimum tax. The Fund will
annually supply shareholders with a report indicating the percentage of
portfolio income attributable to municipal obligations subject to the
alternative minimum tax. Additionally, taxpayers must disclose to the Internal
Revenue Service on their tax returns the entire amount of tax-exempt interest
(including exempt-interest dividends on shares of the Fund) received or accrued
during the year.

     In addition, for corporations, the alternative minimum taxable income is
increased by a percentage of the amount by which an alternative measure of
income ("adjusted current earnings", referred to as "ACE") exceeds the amount
otherwise determined to be the alternative minimum taxable income. Interest on
all municipal obligations, and therefore all exempt-interest dividends paid by
the Fund, is included in calculating ACE. Taxpayers that may be subject to the
alternative minimum tax should consult their tax advisers before investing in
the Fund.

     Under the Omnibus Budget Reconciliation Act of 1993, all or a portion of
the National Municipal Bond Fund's gain from the sale or redemption of tax-
exempt obligations acquired after April 30, 1993 attributable to market discount
will be treated as ordinary income rather than capital gain. This rule may
increase the amount of ordinary income dividends received by shareholders.

     Shares of the Fund would not be a suitable investment for tax-exempt
institutions and may not be a suitable investment for retirement plans qualified
under Section 401 of the Code, H.R. 10 plans and individual retirement accounts,
because such plans and accounts are generally tax-exempt and, therefore, would
not gain any additional benefit from the receipt of exempt-interest dividends
from the Fund. Moreover, subsequent distributions of such dividends to the
beneficiaries will be taxable.

     In addition, the Fund may not be an appropriate investment for entities
that are "substantial users" of facilities financed by private activity bonds or
"related persons" thereof. A "substantial user" is defined under United States
Treasury Regulations to include a non-exempt person who regularly uses a part of
such facilities in his trade or business and, unless such facility, or part
thereof, is constructed, reconstructed or acquired specifically for the non-
exempt person, whose gross revenue derived with respect to the facilities
financed by the issuance of bonds is more than 5% of the total revenue derived
by all users of such facilities. "Related persons" include certain related
natural persons, affiliated corporations, partnerships and their partners and S
Corporations and their shareholders. The foregoing is not a complete statement
of all of the provisions of the Code covering the definitions of "substantial
user" and "related person". For additional information, investors should consult
their tax advisers before investing in the Fund.

     In addition, 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. The Code may also require shareholders
that receive exempt-interest dividends to treat as taxable income a portion of
certain otherwise nontaxable social security and railroad retirement benefit
payments.

                             DEBT SECURITY RATINGS

Standard & Poor's Ratings Service ("S&P")

Commercial Paper:

A-1

              The rating A-1 is the highest rating assigned by S&P to commercial
              paper. This designation indicates that the degree of safety
              regarding timely payment is either overwhelming or very strong.
              Those issues determined to possess overwhelming safety
              characteristics are denoted with a plus (+) sign designation.

A-2

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

Bonds:

AAA

              Debt rated AAA has the highest rating assigned by S&P. 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 higher rated issues only in 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.

BB-B- CCC-CC

              Bonds rated BB, B, CCC and CC are regarded, on balance, as
              predominantly speculative with respect to the issuer's capacity to
              pay interest and repay principal in accordance with the terms of
              the obligations. BB indicates the lowest degree of speculation and
              CC the highest degree of speculation. While such bonds will likely
              have some quality and protective characteristics, these are
              outweighed by large uncertainties or major risk exposures to
              adverse conditions.

D

              Bonds rated D are in default. The D category is used when interest
              payments or principal payments are not made on the date due even
              if the applicable grace period has not expired. The D rating is
              also used upon the filing of a bankruptcy petition if debt service
              payments are jeopardized.

The ratings set forth above may be modified by the addition of a plus or minus
to show relative standing within the major rating categories.

Moody's Investors Service, Inc. ("Moody's")

Commercial Paper:

P-1

              The rating P-1 is the highest commercial paper rating assigned by
              Moody's. Issuers rated P-1 (or related supporting institutions)
              have a superior capacity for repayment of short-term promissory
              obligations. P-1 repayment capacity will normally be evidenced by
              the following characteristics: (1) leading market positions in
              established industries; (2) high rates of return on funds
              employed; (3) conservative capitalization structures with moderate
              reliance on debt and ample asset protection; (4) broad margins in
              earnings coverage of fixed financial charges and high internal
              cash generation; and (5) well established access to a range of
              financial markets and assured sources of alternate liquidity.

P-2

              Issuers rated P-2 (or related supporting institutions) have a
              strong capacity for repayment of short-term promissory
              obligations. This will normally be evidenced by many of the
              characteristics cited above but to a lesser degree. Earnings
              trends and coverage ratios, while sound, will be more subject to
              variation. Capitalization characteristics, while still
              appropriate, may be more affected by external conditions. Ample
              alternative liquidity is maintained.

Bonds:

Aaa

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

Aa

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

A

              Bonds which are rated A by Moody's possess many favorable
              investment attributes and are to be considered as upper medium
              grade obligations. Factors giving security to principal and
              interest are considered adequate but elements may be present which
              suggest a susceptibility to impairment sometime in the future.

Baa

              Bonds which are rated Baa by Moody's are considered as medium
              grade obligations, that is, 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 which are rated Ba are judged to have speculative elements;
              their future cannot be considered as well assured. Often the
              protection of interest and principal payments may be very moderate
              and thereby not well safeguarded during other good and bad times
              over the future. Uncertainty of position characterizes bond in
              this class.

                                      -67-
<PAGE>
 
B

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

Caa

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

Ca

              Bonds which are rated Ca represent obligations which are
              speculative in high degree. Such issues are often in default or
              have other marked shortcomings.

C

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

Moody's applies numerical modifiers "1", "2" and "3" to certain of its
rating classifications. 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.


Fitch Investors Service, Inc. ("Fitch")

Commercial Paper:

F-1+

              Exceptionally strong credit quality. Issues assigned this rating
              are regarded as having the strongest degree of assurance for
              timely payment.

F-1

              Very strong credit quality. Issues assigned this rating reflect an
              assurance of timely payment only slightly less in degree than
              issues rated "F -1+".

F-2

              Issues assigned this rating have a satisfactory degree of
              assurance for timely payment but the margin of safety is not as
              great as for issues assigned "F-1+" or "F-1".
              Bonds:

AAA

              Bonds considered to be investment grade and of the highest credit
              quality. The obligor has an exceptionally strong ability to pay
              interest and repay principal, which is unlikely to be affected by
              reasonably foreseeable events.

AA

              Bonds considered to be investment grade and of very high credit
              quality. The obligor's ability to pay interest and repay principal
              is very strong, although not quite as strong as bonds rated
              "AAA". Because bonds rated in the "AAA" and "AA" categories
              are not significantly vulnerable to foreseeable future
              developments, short-term debt of these issuers is generally rated
              "F-1+".

                                      -68-
<PAGE>
 
A

              Bonds considered to be investment grade and of high credit
              quality. The obligor's ability to pay interest and repay principal
              is considered to be strong, but may be more vulnerable to adverse
              changes in economic conditions and circumstances than bonds with
              higher ratings.

BBB

              Bonds considered to be investment grade and of satisfactory credit
              quality. The obligor's ability to pay interest and repay principal
              is considered to be adequate. Adverse changes in economic
              conditions and circumstances, however, are more likely to have
              adverse impact on these bonds, and therefore impair timely
              payment. The likelihood that the ratings of these bonds will fall
              below investment grade is higher than for bonds with higher
              ratings.

BB

              Bonds are considered speculative. The obligor's ability to pay
              interest and repay principal may be affected over time by adverse
              economic changes. However, business and financial alternatives can
              be identified which could assist the obligor in satisfying its
              debt service requirements.

B

              Bonds are considered highly speculative. While bonds in this class
              are currently meeting debt service requirements, the probability
              of continued timely payment of principal and interest reflects the
              obligor's limited margin of safety and the need for reasonable
              business and economic activity throughout the life of the issue.

CCC

              Bonds have certain identifiable characteristics which, if not
              remedied, may lead to default. The ability to meet obligations
              requires an advantageous business and economic environment.

CC

              Bonds are minimally protected. Default in payment of interest
              and/or principal seems probable over time.

C

              Bonds are in imminent default in payment of interest or principal.

DDD-DD-

              Bonds are in default on interest and/or principal payments. Such
              bonds are extremely speculative and should be valued on

and D

              the basis of their ultimate recovery value in liquidation or
              reorganization of the obligor. "DDD" represents the highest
              potential for recovery on these bonds, and "D" represents the
              lowest potential for recovery.

Plus and minus signs are used with a rating symbol to indicate the relative
position of a credit within the rating category. Plus and minus signs, however,
are not used in the "AAA" category.
