INTRODUCTION

Each Fund is a mutual fund. A mutual fund pools shareholders' money and, using
professional investment managers, invests it in securities.

Fund performance is measured against an index.
An index measures the market prices of a specific group of securities in a
particular market or securities in a market sector. You cannot invest directly
in an index. Unlike a mutual fund, an index does not have an investment adviser
and does not pay any commissions or expenses. If an index had expenses, its
performance would be lower.

Class A and Class B Shares have different expenses and other characteristics,
allowing you to choose the class that best suits your needs. You should consider
the amount you want to invest, how long you plan to have it invested, and
whether you plan to make additional investments.

      Class A Shares
      - Front-end sales charge
      - 12b-1 fees
      - $500 minimum initial investment

      Class B Shares
      - Contingent deferred sales charge
      - Higher 12b-1 fees
      - $500 minimum initial investment

RISK/RETURN SUMMARY

Each Fund has its own investment goal and strategies for reaching that goal. The
investment managers invest Fund assets in a way that they believe will help a
Fund achieve its goal. Still, investing in each Fund involves risk and there is
no guarantee that a Fund will achieve its goal. An investment manager's
judgments about the markets, the economy, or companies may not anticipate actual
market movements, economic conditions or company performance, and these
judgments may affect the return on your investment.

No matter how good a job an investment manager does, you could lose money on
your investment in a Fund, just as you could with other investments.

An investment in a Fund is not a bank deposit and it is not insured or
guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any government
agency.

Although a money market fund seeks to keep a constant price per share of $1.00,
there is no guarantee that a money market fund will achieve this goal and it is
possible that you may lose money by investing in the fund.

The value of your investment in a Fund (other than a money market fund) is based
primarily on the market value of the securities the Fund holds. These prices
change daily due to economic and other events that affect particular companies
and other issuers. These price movements, sometimes called volatility, may be
greater or lesser depending on the types of securities a Fund owns and the
markets in which they trade. The effect on a Fund of a change in the value of a
single security will depend on how widely the Fund diversifies its holdings.

FUND SUMMARY

INVESTMENT GOAL
Capital appreciation

INVESTMENT FOCUS
Equity securities of foreign issuers

SHARE PRICE VOLATILITY
(RELATIVE TO MUTUAL FUNDS GENERALLY)
High

PRINCIPAL INVESTMENT STRATEGY
Investing in equity securities of issuers located in at least three foreign
countries


INVESTOR PROFILE
Investors seeking capital appreciation, who are willing to accept the risks of
foreign investing


PRINCIPAL INVESTMENT STRATEGIES

The Armada International Equity Fund's investment objective is to provide
capital appreciation by investing in a portfolio of equity securities of foreign
issuers. Equity securities of foreign issuers includes common stock, preferred
stock and convertible bonds, of companies headquartered outside the United
States. The investment objective may be changed without a shareholder vote. The
Fund will normally invest at least 80% of its total assets in the equity
securities of foreign issuers. The Fund focuses on issuers included in the
Morgan Stanley Capital International Europe, Australasia, Far East (World EAFE)
Index. The World EAFE is an unmanaged index which represents the performance of
more than 1,000 equity securities of companies located in those regions. The
Adviser makes judgements about the attractiveness of countries based upon a
collection of criteria. The relative valuation, growth prospects, fiscal,
monetary and regulatory government policies are considered jointly and generally
in making these judgements. The percentage of the Fund in each country is
determined by its relative attractiveness and weight in the World EAFE Index.
More than 25% of the Fund's assets may be invested in the equity securities of
issuers located in the same country. Within foreign markets, the Adviser buys
and sells securities based on its analysis of competitive position and
valuation. The Adviser sells securities whose competitive position is
deteriorating or whose valuation is unattractive relative to industry peers.
Likewise, companies with strong and durable competitive advantages and
attractive valuation are considered for purchase.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity
securities may fluctuate from day-to-day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by such companies may decline in
response. These factors contribute to price volatility, which is the principal
risk of investing in the Fund.

Investing in foreign countries poses additional risks since political and
economic events unique to a country or region will affect those markets and
their issuers. These events will not necessarily affect the U.S. economy or
similar issuers located in the United States. In addition, investments in
foreign countries are generally denominated in a foreign currency. As a result,
changes in the value of those currencies compared to the U.S. dollar may affect
(positively or negatively) the value of a Fund's investments. These currency
movements may happen separately from and in response to events that do not
otherwise affect the value of the security in the issuer's home country.

Companies making up the World EAFE Index are generally issuers of larger cap
securities of multi-national companies who are affected by risks worldwide.

Investment in a particular country of 25% or more of the Fund's total assets
will make the Fund's performance more dependent upon the political and economic
circumstances of that country than a mutual fund more widely diversified among
issuers in different countries.

The Fund is also subject to the risk that its market segment, international
equity securities, may underperform other equity market segments or the equity
market as a whole. For additional information about risks, see "More Information
About Risk."

PERFORMANCE INFORMATION

The bar chart and the performance table below illustrate the volatility of an
investment in the Fund. Of course, the Fund's past performance does not
necessarily indicate how the Fund will perform in the future.

There is no performance information for Class B Shares because it has not
completed a full calendar year of operations.

The performance of Class A and Class B Shares will differ due to differences in
expenses.

The chart does not reflect sales charges. If sales charges had been reflected,
returns would be less than those shown below would.

(2) This amount applies to redemptions during the first and second years.
    The deferred sales charge decreases to 4.0%, 3.0% and 2.0% for redemptions
    made during the third through fifth years, respectively. No deferred sales
    charge is charged after the fifth year. For more information see "Selling
    Fund Shares."

(3) The Fund's total actual annual operating expenses for the most recent
    fiscal year were less than the amount shown above because the Distributor is
    waiving a portion of the fees in order to keep total operating expenses at a
    specified level. The Distributor may discontinue all or part of these
    waivers at any time. With these fee waivers, the Fund's actual total
    operating expenses are 1.67%.

For more information about these fees, see "Investment Adviser, Sub-Adviser and
Investment Team" and "Distribution of Fund Shares."

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds. The Example assumes that you
invest $10,000 in the Fund for the time periods indicated and that you sell your
shares at the end of the period.

The Example also assumes that each year your investment has a 5% return and Fund
expenses remain the same. Although your actual costs and returns might be
different, your approximate costs of investing $10,000 in the Fund would be:

If you sell your shares at the end of the period:
                     1 YEAR    3 YEARS    5 YEARS   10 YEARS

Class A Shares       $716      $1,065     $1,437    $2,479

FUND SUMMARY

INVESTMENT GOAL
Capital appreciation

INVESTMENT FOCUS
Small cap equity securities

SHARE PRICE VOLATILITY
(RELATIVE TO MUTUAL FUNDS GENERALLY)
High

PRINCIPAL INVESTMENT STRATEGY
Investing in value-oriented equity securities of smaller issuers


INVESTOR PROFILE
Investors seeking capital appreciation, who are willing to accept the risk of
share price volatility that may accompany small cap investing

PRINCIPAL INVESTMENT STRATEGIES

The Armada Small Cap Value Fund's investment objective is to provide capital
appreciation by investing in a diversified portfolio of publicly traded small
cap equity securities. The investment objective may be changed without a
shareholder vote. The Fund will normally invest at least 80% of its total assets
in the common stocks of small capitalization companies. The Fund may invest up
to 20% of its total assets at the time of purchase in foreign equity securities.
In buying and selling securities for the Fund, the Adviser uses a value-oriented
approach. The Adviser generally seeks to invest in equity securities based upon
price/earnings, price/book and price/cash flow ratios which are lower than the
market averages. The Adviser generally sells securities based upon
price/earnings, price/book and price/cash flow ratios which rise above market
averages or when a company no longer has a small capitalization.

The Fund considers a small capitalization or "small cap" company to be one that
has a comparable market capitalization to the companies in the Russell 2000
Value Index. The Russell 2000 Value Index is an unmanaged index comprised of
securities in the Russell 2000 Index which have a less than average growth
orientation.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may increase transaction costs and capital gains tax liabilities, and will
lower Fund performance.

PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity
securities may fluctuate from day-to-day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by such companies may decline in
response. These factors contribute to price volatility, which is the principal
risk of investing in the Fund.

Smaller capitalization companies may be more vulnerable to adverse business
or economic events than larger, more established companies. In particular, these
companies may have limited product lines, markets and financial resources, and
may depend upon a relatively small management group. Therefore, small cap stocks
may be more volatile than those of larger companies. These securities may be
traded over-the-counter or listed on an exchange and may or may not pay
dividends.

Investing in foreign countries poses additional risks since political and
economic events unique to a country or region will affect those markets and
their issuers. These events will not necessarily affect the U.S. economy or
similar issuers located in the United States. In addition, investments in
foreign countries are generally denominated in a foreign currency. As a result,
changes in the value of those currencies compared to the U.S. dollar may affect
(positively or negatively) the value of a Fund's investments. These currency
movements may happen separately from and in response to events that do not
otherwise affect the value of the security in the issuer's home country.

The Fund is also subject to the risk that its market segment, small cap equity
securities, may underperform other equity market segments or the equity market
as a whole. For additional information about risks, see "More Information About
Risk."

PRINCIPAL INVESTMENT STRATEGIES

The Armada Small Cap Growth Fund's investment objective is to provide capital
appreciation by investing in a diversified portfolio of publicly traded small
cap equity securities. The investment objective may be changed without a
shareholder vote. The Fund normally invests at least 80% of its total assets in
the common stocks of companies with small stock market capitalizations. The Fund
may invest up to 20% of its total assets at the time of purchase in foreign
equity securities. The Adviser seeks to invest in small capitalization companies
with strong growth in revenue, earnings, and cash flow. Purchase decisions are
also based on the security's valuation relative to the company's expected growth
rate, earnings quality and competitive position, valuation compared to similar
securities, and the security's trading liquidity. Reasons for selling securities
include disappointing fundamentals, negative industry developments, evidence of
management's inability to execute a sound business plan, capitalization
exceeding the Adviser's definition of "small capitalization", desire to reduce
exposure to an industry or sector, and valuation levels which cannot be
justified by the company's fundamental growth prospects.

The Fund considers a small capitalization or "small cap" company to be one that
has a comparable market capitalization to the companies in the Russell 2000
Growth Index. The Russell 2000 Growth Index is an unmanaged index comprised of
securities in the Russell 2000 Index which have a less than average growth
orientation.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity
securities may fluctuate from day-to-day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by such companies may decline in
response. These factors contribute to price volatility, which is the principal
risk of investing in the Fund.

The smaller capitalization companies the Fund invests in may be more vulnerable
to adverse business or economic events than larger, more established companies.
In particular, these small companies may have limited product lines, markets and
financial resources, and may depend upon a relatively small management group.
Therefore, small cap stocks may be more volatile than those of larger companies
may. These securities may be traded over-the-counter or listed on an exchange
and may or may not pay dividends.

Investing in foreign countries poses additional risks since political and
economic events unique to a country or region will affect those markets and
their issuers. These events will not necessarily affect the U.S. economy or
similar issuers located in the United States. In addition, investments in
foreign countries are generally denominated in a foreign currency. As a result,
changes in the value of those currencies compared to the U.S. dollar may affect
(positively or negatively) the value of a Fund's investments. These currency
movements may happen separately from and in response to events that do not
otherwise affect the value of the security in the issuer's home country.

The Fund is also subject to the risk that its market segment, small cap equity
securities, may underperform other equity market segments or the equity market
as a whole. For additional information about risks, see "More Information About
Risk."

PRINCIPAL INVESTMENT STRATEGIES

The Armada Equity Growth Fund's investment objective is to provide capital
appreciation by investing in a diversified portfolio of publicly traded larger
cap equity securities. The investment objective may be changed without
shareholder vote. The Fund will normally invest at least 80% of its total assets
in a diversified portfolio of common stocks and securities convertible into
common stocks of companies with large stock market capitalization. The Fund may
invest up to 20% of its total assets at the time of purchase in foreign equity
securities. In buying and selling securities for the Fund, the Adviser considers
factors such as historical and projected earnings growth, earnings quality and
liquidity. The Fund generally purchases common stocks that are listed on a
national securities exchange or unlisted securities with an established
over-the-counter market.

The Fund considers a large capitalization or "large cap" company to be one that
has a comparable market capitalization to the companies in the S&P 500 Composite
Index. The S&P 500 Composite Index is a widely recognized, unmanaged index of
500 common stocks which are generally representative of the U.S. stock market as

INVESTOR PROFILE
Investors who are seeking capital appreciation while minimizing the impact of
taxes and who are willing to accept the risk of investing in equity securities

PRINCIPAL INVESTMENT STRATEGIES

The Armada Tax Managed Equity Fund's investment objective is to provide capital
appreciation while minimizing the impact of taxes on shareholders' returns. The
investment objective may be changed without a shareholder vote. The Fund
normally invests at least 80% of the Fund's total assets in common stocks. The
Fund may invest up to 20% of its total assets at the time of purchase in foreign
equity securities. Equity securities of foreign issuers include common,
preferred and convertible bonds, of companies headquartered outside the United
States. The Adviser buys and sells common stocks based on factors such as
historical and projected long-term earnings growth, earnings quality and
liquidity. The Adviser attempts to minimize the realization of taxable gains by
investing in the securities of companies with above average earnings
predictability and stability which the Fund expects to hold for several years.
This generally results in a low level of portfolio turnover. In addition, the
Fund seeks to distribute relatively low levels of taxable investment income by
investing in stocks with low dividend yields. When the Fund sells appreciated
securities, it will attempt to select the share lots with the highest cost basis
in order to hold realized capital gains to a minimum. The Fund may, when
consistent with its overall investment approach, sell depreciated securities to
offset realized capital gains. The Fund may make in-kind redemptions consistent
with its investment objective. An in-kind redemption may serve to minimize any
tax impact on the remaining shareholders, because the Fund generally recognizes
no taxable gain (or loss) on the securities used to make an in-kind redemption.
The Fund is not a tax exempt fund, and it expects to distribute taxable
dividends and capital gains from time to time.

PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity
securities may fluctuate from day-to-day. Individual companies may report poor

The performance of the Armada Tax Managed Equity Fund for the period prior to
May 11, 1998 is represented by the performance of a common trust fund ("common
trust fund") which operated prior to the effectiveness of the registration
statement of the Tax Managed Equity Fund. The common trust fund was advised by
National City Bank, an affiliate of the Adviser. At the time of the Tax Managed
Equity Fund's inception, the common trust fund was operated using materially
equivalent investment objectives, policies, guidelines and restrictions as the
Fund. In connection with the Tax Managed Equity Fund's commencement of
operations, on May 11, 1998, the common trust fund transferred its assets to the
Fund. At the time of the transfer, the Adviser did not manage any other
collective investment or common trust funds using materially equivalent
investment objectives, policies, guidelines and restrictions to those of the Tax
Managed Equity Fund.

The common trust fund was not open to the public generally, nor registered under
the Investment Company Act of 1940 (the "1940 Act") or subject to certain
restrictions that are imposed by the 1940 Act and the Internal Revenue Code. If
the common trust fund had been registered under the 1940 Act, performance may
have been adversely affected. Performance quotations of the common trust fund
represent past performance of the Adviser managed common trust fund, which are
separate and distinct from the Tax Managed Equity Fund; do not represent past
performance of the Fund; and should not be considered as representative of
future results of the Fund.

PRINCIPAL INVESTMENT STRATEGY
Investing in large capitalization common stocks

INVESTOR PROFILE
Investors seeking capital appreciation, who are willing to accept the risk of
investing in equity securities

PRINCIPAL INVESTMENT STRATEGIES

The Armada Core Equity Fund's investment objective is to provide capital
appreciation by blending value and growth investment styles. The investment
objective may be changed without a shareholder vote. The Fund normally invests
at least 80% of its total assets in a diversified portfolio of common stocks and
securities convertible into common stocks of companies with large stock market
capitalizations. The Sub-Adviser will normally invest between 20% and 50% of its
assets in the following three types of equity securities: (1) common stocks that
meet the Sub-Adviser's criteria for five-year annual earnings-per-share rate
during the last five years; (2) common stocks with price-to-earnings ratios
below the average of the companies included in the S&P 500 Composite Index; and
(3) common stocks that pay dividends at a rate above the average of the
companies included in the S&P Composite Index.

The Sub-Adviser utilizes a systematic, discipline investment process when
selecting individual securities. This includes: (1) screening a database for
liquidity and the criteria listed above; (2) scoring each issue emphasizing
fundamental, valuation and technical indicators; and (3) security analysis that
further evaluates the company and the stock, which includes an analysis of
company fundamentals such as earnings, profitability and management, valuation
such as price/earnings, price/book and yield, and technical analysis emphasizing
individual stock price trends.

The sell discipline involves the monitoring of each company's fundamental,
valuation, and technical measures. If one of these measures is unfavorable, an
immediate review of that company is performed. If two of these three measures
are unfavorable, that stock is sold. The Fund may invest up to 20% of its total
assets at the time of purchase in foreign equity securities.

The Fund considers a large capitalization or "large cap" company to be one that
has a comparable market capitalization to the companies in the S&P 500 Composite
Index. The S&P 500 Composite Index is a widely recognized, unmanaged index of
500 common stocks which are generally representative of the U.S. stock market as
a whole.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity
securities may fluctuate from day-to-day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by such companies may decline in
response. These factors contribute to price volatility, which is the principal
risk of investing in the Fund.

Investing in foreign countries poses additional risks since political and
economic events unique to a country or region will affect those markets and
their issuers. These events will not necessarily affect the U.S. economy or
similar issuers located in the United States. In addition, investments in
foreign countries are generally denominated in a foreign currency. As a result,
changes in the value of those currencies compared to the U.S. dollar may affect
(positively or negatively) the value of a Fund's investments. These currency
movements may happen separately from and in response to events that do not
otherwise affect the value of the security in the issuer's home country.

The Fund is also subject to the risk that its market segment, large cap equity
securities, may underperform other equity market segments or the equity market
as a whole. For additional information about risks, see "More Information About
Risk."

PRINCIPAL INVESTMENT STRATEGY

INVESTOR PROFILE
Investors seeking returns similar to the S&P 500 Composite Index, who are
willing to accept the risk of investing in equity securities

PRINCIPAL INVESTMENT STRATEGIES

The Armada Equity Index Fund's investment objective is to provide investment
results that, before Fund expenses, approximate the aggregate price and dividend
performance of the securities included in the S&P 500 Composite Index by
investing in securities comprising the S&P 500 Composite Index. The investment
objective may be changed without a shareholder vote. The S&P 500 Composite Index
is made up of common stocks of 500 large, publicly traded companies. The Fund
buys and holds all stocks included in the S&P 500 Composite Index in exactly the
same proportion as those stocks are held in the Index. Stocks are eliminated
from the Fund when removed from the S&P 500 Composite Index. The Adviser makes
no attempt to "manage" the Fund in the traditional sense (i.e., by using
economic, financial or market analyses).

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity
securities may fluctuate from day-to-day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by such companies may decline in
response. These factors contribute to price volatility, which is the principal
risk of investing in the Fund.

The Fund is also subject to the risk that its market segment, the S&P 500
Composite Index of common stocks, may underperform other equity market segments
or the equity market as a whole.

The Fund's ability to duplicate the performance of the S&P 500 Composite Index
will depend to some extent on the size and timing of cash flows into and out of
the Fund, as well as on the level of the Fund's expenses. For additional
information about risks, see "More Information About Risk."

INVESTOR PROFILE
Investors seeking an income component as well as capital appreciation and who
are willing to accept the risk of investing in equity securities

PRINCIPAL INVESTMENT STRATEGIES

The Armada Equity Income Fund's investment objective is to provide capital
appreciation by investing in a diversified portfolio of publicly traded equity
securities which, in the aggregate, provide a premium current yield. Equity
securities include public and privately issued equity securities, common and
preferred stocks, warrants, rights to subscribe to common stock and convertible
securities, as well as instruments that attempt to track the price movement of
equity indices. The investment objective may be changed without a shareholder
vote.

The Fund normally invests at least 80% of its total assets in common stocks and
securities convertible into common stocks of companies that have the ability to
pay dividends with a yield above the S&P 500 Composite Index. The Fund may
invest up to 20% of its total assets at the time of purchase in foreign equity
securities. In buying and selling securities for the Fund, the Adviser
emphasizes equity securities and convertible securities that provide a higher
yield than the general market. The Fund will generally sell securities when
their yields approach a market yield or they otherwise fail to satisfy
investment criteria.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity
securities may fluctuate from day-to-day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by such companies may decline in
response. These factors contribute to price volatility, which is the principal
risk of investing in the Fund.

Investing in foreign countries poses additional risks since political and
economic events unique to a country or region will affect those markets and
their issuers. These events will not necessarily affect the U.S. economy or
similar issuers located in the United States. In addition, investments in
foreign countries are generally denominated in a foreign currency. As a result,
changes in the value of those currencies compared to the U.S. dollar may affect
(positively or negatively) the value of a Fund's investments. These currency
movements may happen separately from and in response to events that do not
otherwise affect the value of the security in the issuer's home country.

The Fund is also subject to the risk that its market segment, income producing
equity securities, may underperform other equity market segments or the equity
market as a whole. For additional information about risks, see "More Information
About Risk."

(RELATIVE TO MUTUAL FUNDS GENERALLY)
Medium

PRINCIPAL INVESTMENT STRATEGY
Investing in a diversified portfolio of growth-oriented common stocks,
investment grade fixed income securities and cash equivalents with varying asset
allocations depending on the Adviser's assessment of market conditions

INVESTOR PROFILE
Investors seeking a broad diversification by asset class and style to manage
risk and provide the potential for above-average total returns (as gauged by the
returns of the S&P 500 Composite Index and the Lehman Brothers Aggregate Bond
Index)

PRINCIPAL INVESTMENT STRATEGIES

The Armada Balanced Allocation Fund's investment objective is to provide
long-term capital appreciation and current income. The investment objective may
be changed without a shareholder vote. The Fund intends to invest 50% to 70% of
its net assets in common stocks and convertible securities, 25% to 55% of its
net assets in investment grade fixed income securities such as corporate bonds
and U.S. Government securities, and up to 30% of its net assets in cash and cash
equivalent securities. The Fund may invest up to 20% of its total assets at the
time of purchase in foreign securities (which include common stock, preferred
stock and convertible bonds of companies headquartered outside the United
States). The Fund also invests in the common stock of small capitalization
companies. The Adviser buys and sells equity securities based on their potential
for long-term capital appreciation. The Fund invests the fixed income portion of
its portfolio of investments in a broad range of investment grade debt
securities (which are those rated at the time of investment in one of the four
highest rating categories by a major rating agency) for current income. If a
fixed income security is downgraded, the Adviser will re-evaluate the holding to
determine whether it is in the best interests of investors to sell. The Adviser
buys and sells fixed income securities and cash equivalents based on a number of
factors, including yield to maturity, maturity, quality and the outlook for
particular issuers and market sectors. The Fund invests in cash equivalent,
short-term obligations for stability and liquidity.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity
securities may fluctuate from day-to-day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by such companies may decline in
response. These factors contribute to price volatility, which is the principal
risk of investing in the Fund.

The prices of the Fund's fixed income securities respond to economic
developments, particularly interest rate changes, as well as to perceptions
about the creditworthiness of individual issuers, including governments.
Generally, the Fund's fixed income securities will decrease in value if interest
rates rise and vice versa, and the volatility of lower rated securities is even
greater than that of higher rated securities. Also, longer-term securities are
generally more volatile, so the average maturity or duration of these securities
affects risk.

The Fund is also subject to the risk that the Adviser's asset allocation
decisions will not anticipate market trends successfully. For example, weighting
common stocks too heavily during a stock market decline may result in a failure
to preserve capital. Conversely, investing too heavily in fixed income
securities during a period of stock market appreciation may result in lower
total return.

The smaller capitalization companies the Fund invests in may be more vulnerable
to adverse business or economic events than larger, more established companies.
In particular, these small companies may have limited product lines, markets and
financial resources, and may depend upon a relatively small management group.
Therefore, small cap stocks may be more volatile than those of larger companies
may. These securities may be traded over-the-counter or listed on an exchange
and may or may not pay dividends.

Investing in foreign countries poses additional risks since political and
economic events unique to a country or region will affect those markets and
their issuers. These events will not necessarily affect the U.S. economy or
similar issuers located in the United States. In addition, investments in
foreign countries are generally denominated in a foreign currency. As a result,
changes in the value of those currencies compared to the U.S. dollar may affect
(positively or negatively) the

value of a Fund's investments. These currency movements may happen separately
from and in response to events that do not otherwise affect the value of the
security in the issuer's home country.

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

Although the Fund's U.S. Government securities are considered to be among the
safest investments, they are not guaranteed against price movements due to
changing interest rates. Obligations issued by some U.S. Government agencies and
instrumentalities are backed by the U.S. Treasury, while others are backed
solely by the ability of the agency to borrow from the U.S. Treasury or by the
agency's own resources.

The Fund is also subject to the risk that its market segments, investment grade
fixed income and growth-oriented equity securities, may underperform other fixed
income or equity market segments or the fixed income or equity markets as a
whole. For additional information about risks, see "More Information About
Risk."

PRINCIPAL INVESTMENT STRATEGY
Investing in investment grade fixed income securities, while maintaining an

INVESTOR PROFILE
Investors seeking total return with less price volatility than would be the case
if the Fund were to invest in equity securities, and who are willing to accept
the risks of investing in fixed income securities

PRINCIPAL INVESTMENT STRATEGIES

The Armada Total Return Advantage Fund's investment objective is to provide
current income as well as preservation of capital by investing primarily in a
portfolio of high- and medium-grade fixed income securities. The investment
objective may be changed without a shareholder vote. The Fund normally invests
at least 80% of the value of its total assets in investment grade fixed income
securities of all types, including asset-backed securities and mortgage-backed
securities and obligations of corporate and U.S. Government issuers. Corporate
obligations may include bonds, notes and debentures. U.S. Government securities
may include U.S. Treasury obligations and obligations of certain U.S. Government
agencies or instrumentalities. Fixed income securities are designed to provide a
fixed rate of interest at maturity and return the principal value at the end of
the term. High and medium-grade fixed income securities are those rated in one
of the four highest rating categories by a major rating agency, or determined by
the Adviser to be of equivalent quality. If a security is downgraded, the
Adviser will re-evaluate whether continuing to hold the security is in the best
interest of shareholders. In buying and selling securities for the Fund, the
Adviser uses a number of strategies, including duration/maturity management,
sector allocation and individual security selection. The Fund may invest up to
15% of its assets in fixed income securities that are non-rated or rated below
investment grade, sometimes known as "junk bonds". The Fund does not invest in
junk bonds rated below C.

The Fund generally maintains an average dollar-weighted maturity of between four
and twelve years.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

The prices of the Fund's fixed income securities respond to economic
developments, particularly interest rate changes, as well as to perceptions
about the creditworthiness of individual issuers, including governments.
Generally, the Fund's fixed income securities will decrease in value if interest
rates rise and vice versa, and the volatility of lower rated securities is even
greater than that of higher rated securities. Also, longer-term securities are
generally more volatile, so the average maturity or duration of these securities
affects risk.

Junk bonds involve greater risks of default or downgrade and are more volatile
than investment grade securities. Junk bonds involve greater risk of default or
price declines than investment grade securities due to actual or perceived
changes in an issuer's creditworthiness. In addition, issuers of junk bonds may
be more susceptible than other issuers to economic downturns. Junk bonds are
subject to the risk that the issuer may not be able to pay interest or dividends
on a timely basis and ultimately to repay principal upon maturity.
Discontinuation of these payments could substantially adversely affect the
market value of the security.

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

                 ARMADA TOTAL RETURN ADVANTAGE FUND (CONTINUED)

PRINCIPAL RISKS OF INVESTING (continued)

The mortgages underlying mortgage-backed securities may
be paid off early, which makes it difficult to determine their actual maturity
and therefore calculate how they will respond to changes in interest rates. The
Fund may have to reinvest prepaid amounts at lower interest rates. This risk of
prepayment is an additional risk of mortgage-backed securities.

Debt extension risk is the risk that an issuer will exercise its right to pay
principal on an obligation held by the Fund (such as an asset-backed security)
later than expected. This may happen during a period of rising interest rates.
Under these circumstances, the value of the obligation will decrease and the
Fund will suffer from the inability to invest in higher yielding securities.

Although the Fund's U.S. Government securities are considered to be among the
safest investments, they are not guaranteed against price movements due to
changing interest rates. Obligations issued by some U.S. Government agencies and
instrumentalities are backed by the full faith and credit of the United States,
while others are backed solely by the ability of the agency to borrow from the
U.S. Treasury or by the agency's own resources.

The Fund is also subject to the risk that its market segment, high and
medium-grade fixed income securities, may underperform other fixed income market
segments or the fixed income market as a whole. For additional information about
risks, see "More Information About Risk."

PRINCIPAL INVESTMENT STRATEGIES

The Armada Intermediate Bond Fund's investment objective is to provide current
income as well as preservation of capital by investing in a portfolio of high-
and medium-grade fixed income securities. The investment objective may be
changed without a shareholder vote. The Fund normally invests at least 80% of
the value of its total assets in domestic and foreign high and medium-grade
fixed income securities of all types, including obligations of corporate and
governmental issuers and mortgage-backed and asset-backed securities. Corporate
obligations include bonds, notes and debentures. Governmental obligations
include securities issued by the U.S. Government, its agencies and
instrumentalities, as well as obligations of foreign governments. High and
medium-grade fixed income securities are those rated in one of the four highest
rating categories by a major rating agency, or determined by the Adviser to be
of equivalent quality. If a security is downgraded, the Adviser will re-evaluate
the holding to determine whether it is in the best interests of investors to
sell. In buying and selling securities for the Fund, the Adviser considers a
number of factors, including yield to maturity, maturity, quality and the
outlook for particular issuers and market sectors. The Fund generally maintains
an average maturity of between three and ten years.

PRINCIPAL RISKS OF INVESTING

The prices of the Fund's fixed income securities respond to economic
developments, particularly interest rate changes, as well as to perceptions
about the creditworthiness of individual issuers, including governments.
Generally, the Fund's fixed income securities will decrease in value if interest
rates rise and vice versa, and the volatility of lower rated securities is even
greater than that of higher rated securities. Also, longer-term securities are
generally more volatile, so the average maturity or duration of these securities
affects risk.

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

The mortgages underlying mortgage-backed securities may be paid off early, which
makes it difficult to determine their actual maturity and therefore calculate
how they will respond to changes in interest rates. The Fund may have to
reinvest prepaid amounts at lower interest rates. This risk of prepayment is an
additional risk of mortgage-backed securities.

Debt extension risk is the risk that an issuer will exercise its right to pay
principal on an obligation held by the Portfolio (such as an asset-backed
security) later than expected. This may happen during a period of rising
interest rates. Under these circumstances, the value of the obligation will
decrease and the Portfolio will suffer from the inability to invest in higher
yielding securities.

Although the Fund's U.S. Government securities are considered to be among the
safest investments, they are not guaranteed against price movements due to
changing interest rates. Obligations issued by some U.S. Government agencies and
instrumentalities are backed by the U.S. Treasury, while others are backed
solely by the ability of the agency to borrow from the U.S. Treasury or by the
agency's own resources.

Investing in foreign countries poses additional risks since political and
economic events unique to a country or region will affect those markets and
their issuers. These events will not necessarily affect the U.S. economy or
similar issuers located in the United States. In addition, investments in
foreign countries are generally denominated in a foreign currency. As a result,
changes in the value of those currencies compared to the U.S. dollar may affect
(positively or negatively) the value of a Fund's investments. These currency
movements may happen separately from and in response to events that do not
otherwise affect the value of the security in the issuer's home country. These
various risks will be even greater for investments in emerging market countries
since political turmoil and rapid

changes in economic conditions are more likely to occur in these countries.

The Fund is also subject to the risk that its market segment, investment grade

the fixed income market as a whole. For additional information about risks, see

INVESTOR PROFILE
Investors seeking current income, and who are willing to accept the risks of
investing in mortgage-backed securities

PRINCIPAL INVESTMENT STRATEGIES

The Armada GNMA Fund's investment objective is to provide current income as well
as preservation of capital by investing primarily in mortgage-backed securities
guaranteed by GNMA. The investment objective may be changed without a
shareholder vote. The Fund normally invests at least 80% of the value of its
total assets in mortgage-backed securities guaranteed by GNMA, which is an
agency of the U.S. Government established to supervise and finance certain types
of mortgages. In addition to mortgage-backed securities, the Fund invests in
other types of investment grade fixed income securities such as U.S. Treasury
obligations, U.S. Government agencies, asset-backed securities and commercial
paper.

In buying and selling securities for the Fund, the Adviser assesses current and
projected market conditions by considering a number of factors including yield
to maturity, maturity, quality and the outlook for particular issuers and market
sectors.

The Fund's dollar-weighted average portfolio maturity will be between three and
ten years. Investment grade fixed income securities are those rated in one of
the four highest rating categories by a major rating agency, or determined by
the Adviser to be of equivalent quality.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

The prices of the Fund's fixed income securities respond to economic
developments, particularly interest rate changes, as well as to perceptions
about the creditworthiness of individual issuers, including governments.
Generally, the Fund's fixed income securities will decrease in value if interest
rates rise and vice versa. Also, longer-term securities are generally more
volatile, so the average maturity or duration of these securities affects risk.

Mortgage-backed securities are fixed income securities representing an interest
in a pool of underlying mortgage loans. They are sensitive to changes in
interest rates, but may respond to these changes differently from other fixed
income securities due to the possibility of prepayment of the underlying
mortgage loans. As a result, it may not be possible to determine in advance the
actual maturity date or average life of a mortgage-backed security. Rising
interest rates tend to discourage refinancings, with the result that the average
life and volatility of the security will increase, exacerbating its decrease in
market price. When interest rates fall, however, mortgage-backed securities may
not gain as much in market value because of the expectation of additional
mortgage prepayments that must be reinvested at lower interest rates. Prepayment
risk may make it difficult to calculate the average maturity of the Fund of
mortgage-backed securities and, therefore, to assess the volatility risk of the
Fund.

Debt extension risk is the risk that an issuer will exercise its right to pay
principal on an obligation held by the Fund (such as an asset-backed security)
later than expected. This may happen during a period of rising interest rates.
Under these circumstances, the value of the obligation will decrease and the
Fund will suffer from the inability to invest in higher yielding securities.

The Fund is also subject to the risk that its market segment, mortgage-backed
securities, may underperform other fixed income market segments or the fixed
income market as a whole.

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

Although the Fund's U.S. Government securities are considered to be among the
safest investments, they are not guaranteed against price movements due to
changing interest rates. Obligations issued by some U.S. Government agencies and
instrumentalities are backed by the U.S. Treasury, while others are backed
solely by the ability of the agency to borrow from the U.S. Treasury or by the
agency's own resources.

PRINCIPAL INVESTMENT STRATEGIES

The Armada Enhanced Income Fund's investment objective is to provide current
income as well as preservation of capital by investing in a portfolio of high-
and medium-grade fixed income securities. The investment objective may be
changed without a shareholder vote. The Fund normally invests at least 80% of
the value of its total assets in high and medium-grade debt securities of all
types, including obligations of corporate and U.S. Government issuers,
mortgage-backed and asset-backed securities. Corporate obligations may include
bonds, notes and debentures. U.S. Government securities may include U.S.
Treasury obligations and obligations of certain U.S. Government agencies or
instrumentalities. High- and medium-grade fixed income securities are those
rated in one of the four highest rating categories by a major rating agency, or
determined by the Adviser to be of equivalent quality. If a security is
downgraded, the Adviser will re-evaluate whether continuing to hold the security
is in the best interest of shareholders. In buying and selling securities for
the Fund, the Adviser considers a number of factors, including yield to
maturity, maturity, quality and the outlook for particular issuers and market
sectors. The Fund generally maintains an average dollar-weighted portfolio
maturity of between one and five years.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

The prices of the Fund's fixed income securities respond to economic
developments, particularly interest rate changes, as well as to perceptions
about the creditworthiness of individual issuers, including governments.
Generally, the Fund's fixed income securities will decrease in value if interest
rates rise and vice versa. Also, longer-term securities are generally more
volatile, so the average maturity or duration of these securities affects risk.

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

The mortgages underlying mortgage-backed securities may be paid off early, which
makes it difficult to determine their actual maturity and therefore calculate
how they will respond to changes in interest rates. The Fund may have to
reinvest prepaid amounts at lower interest rates. This risk of prepayment is an
additional risk of mortgage-backed securities.

Debt extension risk is the risk that an issuer will exercise its right to pay
principal on an obligation held by the Fund (such as an asset-backed security)
later than expected. This may happen during a period of rising interest rates.
Under these circumstances, the value of the obligation will decrease and the
Fund will suffer from the inability to invest in higher yielding securities.

Although the Fund's U.S. Government securities are considered to be among the
safest investments, they are not guaranteed against price movements due to
changing interest rates. Obligations issued by some U.S. Government agencies and
instrumentalities are backed by the U.S. Treasury, while others are backed
solely by the ability of the agency to borrow from the U.S. Treasury or by the
agency's own resources.

The Fund is also subject to the risk that its market segment, investment grade
fixed income securities, may underperform other fixed income market segments or
the fixed income market as a whole. For additional information about risks, see
"More Information About Risk."

PERFORMANCE INFORMATION

The bar chart and the performance table below illustrate the volatility of an
investment in the Fund. Of course, the Fund's past performance does not
necessarily indicate how the Fund will perform in the future.

There is no performance information for Class B Shares because it has not
completed a full calendar year of operations.

The performance of Class A and Class B Shares will differ due to differences in
expenses.

This bar chart shows changes in the performance of the Fund's Class A
Shares from year to year.

PRINCIPAL INVESTMENT STRATEGIES

The Armada Ohio Tax Exempt Bond Fund's investment objective is to provide
current income exempt from federal income tax and, to the extent possible, from
Ohio personal income tax, as is consistent with the conservation of capital. The
investment objective may be changed without a shareholder vote. The Fund
normally invests at least 80% of its total assets in debt securities issued by
the State of Ohio, its political subdivisions and their agencies and
instrumentalities that generate income exempt from federal income and Ohio
personal income taxes (Ohio municipal securities). However, some Fund dividends
will be taxable, such as dividends that are derived from occasional taxable
investments and distributions of short and long-term capital gains. Also, Fund
dividends will generally be subject to state and local income taxes for any
shareholders who are not Ohio residents. The Fund may invest up to 20% of its
total assets in private activity bonds which may be treated as a specific tax
preference item under the federal alternative minimum tax. In selecting
securities for the Fund to buy and sell, the Adviser considers each security's
yield and total return potential relative to other available municipal
securities.

The Fund invests primarily in investment grade securities, which are those rated
in one of the four highest rating categories by a major rating agency, or
determined by the Adviser to be of equivalent quality. If a security is
downgraded, the Adviser will re-evaluate whether continuing to hold the security
is in the best interest of its shareholders. The Fund ordinarily will maintain
an average weighted portfolio maturity of between three and ten years.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and capital gains tax liabilities,
and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

The prices of the Fund's fixed income securities respond to economic
developments, particularly interest rate changes, as well as to perceptions
about the creditworthiness of individual issuers, including governments.
Generally, the Fund's fixed income securities will decrease in value if interest
rates rise and vice versa. Also, longer-term securities are generally more
volatile, so the average maturity or duration of these securities affects risk.

The Fund is also subject to the risk that its market segment, tax exempt
municipal securities, may underperform other fixed income market segments or the
fixed income market as a whole.

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

There may be economic or political changes that impact the ability of municipal
issuers to repay principal and to make interest payments on municipal
securities. Changes in the financial condition or credit rating of municipal
issuers also may adversely affect the value of the Fund's securities.

The Fund's focus of investing in securities of issuers located in a Ohio
subjects the Fund to economic and government policies of that state.

The Fund is non-diversified, which means that it may invest in the securities of
relatively few issuers. As a result, the Fund may be more susceptible than a
diversified fund to a single adverse economic or political and regulatory
occurrences affecting one or more of these issuers, and may experience increased
volatility due to its investments in those securities. For additional
information about risks, see "More Information About Risk."

FUND SUMMARY

conservation of capital

INVESTMENT FOCUS
Municipal securities

SHARE PRICE VOLATILITY
(RELATIVE TO MUTUAL FUNDS GENERALLY)
Medium

PRINCIPAL INVESTMENT STRATEGY
Investing in municipal obligations that pay interest that is exempt from federal
income tax

INVESTOR PROFILE
Investors seeking tax exempt current income, and who are willing to accept
moderate share price volatility

PRINCIPAL INVESTMENT STRATEGIES

The Armada National Tax Exempt Bond Fund's investment objective is to provide
current income exempt from federal income tax as is consistent with conservation
of capital. The investment objective may be changed without a shareholder vote.
The Fund normally invests at least 80% of its net assets in debt securities that
generate income exempt from federal income tax. However, Fund dividends will
generally be taxable for state and local income tax purposes. Also, some Fund
dividends will be taxable for federal income tax purposes, such as those derived
from occasional taxable investments and distributions of short and long-term
capital gains. The Fund may invest up to 20% of its total assets in private
activity bonds, the income of which may be treated as a specific tax preference
item under the federal alternative minimum tax. The Fund invests in municipal
securities issued by or on behalf of states, territories and possessions of the
United States, the District of Columbia and their political subdivisions,
agencies, instrumentalities and authorities. In selecting securities for the
Fund to buy and sell, the Adviser considers each security's yield and total
return potential relative to other available municipal securities.

The Fund primarily invests only in investment grade securities. Investment grade
municipal securities are those rated in one of the four highest rating
categories as determined by a major rating agency. If a security is downgraded,
the Adviser will re-evaluate whether continuing to hold the security is in the
best interest of shareholders. The Fund ordinarily will maintain a
dollar-weighted average portfolio maturity of between three and ten years.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and capital gains tax liabilities,
and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

The prices of the Fund's fixed income securities respond to economic
developments, particularly interest rate changes, as well as to perceptions
about the creditworthiness of individual issuers, including governments.
Generally, the Fund's fixed income securities will decrease in value if interest
rates rise and vice versa. Also, longer-term securities are generally more
volatile, so the average maturity or duration of these securities affects risk.

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

There may be economic or political changes that impact the ability of municipal
issuers to repay principal and to make interest payments on municipal
securities. Changes in the financial condition or credit rating of municipal
issuers also may adversely affect the value of the Fund's securities.

The Fund is also subject to the risk that its market segment, tax exempt
securities, may underperform other fixed income market segments or the fixed
income market as a whole. For additional information about risks, see "More
Information About Risk."

PERFORMANCE INFORMATION

The bar chart and the performance table below illustrate the volatility of an
investment in the Fund. Of course, the Fund's past performance does not
necessarily indicate how the Fund will perform in the future.

There is no performance information for Class B Shares because it has not
completed a full calendar year of operations.

The performance of Class A and Class B Shares will differ due to differences in
expenses.

This bar chart shows changes in the performance of the
Fund's Class A Shares from year to year.

This bar chart does not reflect sales charges. If sales charges had been
reflected, returns would be less than those shown below.

return index. The bonds are all investment grade, fixed rate
with maturities of 9-12 years and are selected from issues
larger than $50 million dated since January 1984.

The performance of the National Tax Exempt Bond Fund for the period prior to
June 22, 1998 is represented by the performance of a common trust fund ("common
trust fund") which operated prior to the effectiveness of the registration
statement of the National Tax Exempt Bond Fund. The common Trust fund was
advised by National City Bank, an affiliate of the Adviser. At the time of the
National Tax Exempt Bond Fund's inception, the common trust fund was operated
using materially equivalent investment objectives, policies, guidelines and
restrictions as the Fund. In connection with the National Tax Exempt Bond Fund's
commencement of operations, on June 22, 1998, the common trust fund transferred
its assets to the Fund. At the time of the transfer, the Adviser did not manage
any other collective investment or common trust funds using materially
equivalent investment objectives, policies, guidelines and restrictions to those
of the National Tax Exempt Bond Fund.

The common trust fund was not open to the public generally, nor registered under
the Investment Company Act of 1940 (the "1940 Act") or subject to certain
restrictions that are imposed by the 1940 Act and the Internal Revenue Code. If
the common trust fund had been registered under the 1940 Act, performance may
have been adversely affected. Performance quotations of the common trust fund
represent past performance of the Adviser managed common trust fund, which are
separate and distinct from the National Tax Exempt Bond Fund; do not represent
past performance of the Fund; and should not be considered as representative of
future results of the Fund.

allow the Fund to maintain a stable net asset value of $1.00 per share


INVESTOR PROFILE
Conservative taxable investors in higher tax brackets seeking current income
exempt from federal and Ohio income taxes


PRINCIPAL INVESTMENT STRATEGIES

The Armada Ohio Municipal Money Market Fund's investment objective is to provide
current income exempt from regular federal income tax and Ohio personal income
tax, consistent with stability of principal. The investment objective may be
changed without a shareholder vote. The Fund invests exclusively in high quality
money market instruments issued by or on behalf of the State of Ohio, political
subdivisions thereof or agencies or instrumentalities of Ohio or its political
subdivisions, the income from which is exempt from regular federal income tax
and Ohio personal income tax (Ohio money market instruments). However, some Fund
dividends may be taxable if the Fund, as it is permitted to do, invests some of
its assets in taxable instruments. Also, Fund dividends will generally be
subject to state and local income taxes for any shareholders who are not Ohio
residents. High quality money market instruments are securities that present
minimal credit risks as determined by the Adviser and generally include
securities that are rated at the time of purchase by a major rating agency in
the two highest rating categories for such securities, and certain securities
that are not rated but are of comparable quality as determined by the Adviser.

The Fund may invest 100% of its assets in private activity bonds, the interest
from which is a preference item for the federal alternative minimum tax. Under
normal market conditions, at least 80% of the value of the Fund's total assets
will be invested in Ohio money market instruments. This policy is fundamental
and may not be changed without the affirmative vote of the holders of a majority
of the Fund's outstanding shares.

In managing the Fund, the Adviser assesses current and projected market
conditions, particularly interest rates. Based on this assessment and a separate
credit analysis, the Adviser uses gradual shifts in portfolio maturity to
respond to expected changes and selects securities that it believes offer the
most attractive risk/return trade off.

As a money market fund, the Fund invests only in instruments with remaining
maturities of 397 days or less that the Adviser believes present minimal credit
risk. The Fund maintains an average weighted maturity of 90 days or less.


PRINCIPAL RISKS OF INVESTING

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

The Fund is also subject to the risk that its market segment, Ohio municipal
money market securities, may underperform other fixed income market segments or
the fixed income market as a whole.

There may be economic or political changes that impact the ability of municipal
issuers to repay principal and to make interest payments on municipal
securities. Changes in the financial condition or credit rating of municipal
issuers also may adversely affect the value of the Fund's securities.

The Fund's focus of investments in securities of issuers located in Ohio
subjects the Fund to economic and government policies of that state. For
additional information about risks, see "More Information About Risk."

The Armada Pennsylvania Tax Exempt Money Market Fund's investment objective is

FUND SUMMARY


INVESTMENT GOAL

High current interest income exempt from federal income tax consistent with
stability of principal while maintaining liquidity


INVESTMENT FOCUS
Municipal money market instruments


SHARE PRICE VOLATILITY
(RELATIVE TO MUTUAL FUNDS GENERALLY)
Very low


PRINCIPAL INVESTMENT STRATEGY
Investing in a portfolio of high quality short-term debt securities designed to
allow the Fund to maintain a stable net asset value of $1.00 per share


INVESTOR PROFILE
Conservative taxable investors in higher tax brackets seeking current income
exempt from federal income taxes


PRINCIPAL INVESTMENT STRATEGIES

The Armada Tax Exempt Money Market Fund's investment objective is to provide as
high a level of current interest income exempt from federal income tax as is
consistent with liquidity and stability of principal. The investment objective
may be changed without a shareholder vote. The Fund invests primarily in high
quality money market instruments issued by or on behalf of states, territories
and possessions of the United States, the District of Columbia and their
political subdivisions, agencies, instrumentalities and authorities that pay
interest exempt from federal taxes (municipal money market instruments).
However, Fund dividends will generally be taxable for state and local income tax
purposes. Also, some Fund dividends may be taxable for federal income tax
purposes if the Fund, as it is permitted to do, invests some of its assets in
taxable instruments. High quality money market instruments are securities that
present minimal credit risks as determined by the Adviser and generally include
securities that are rated at the time of purchase by a major rating agency in
the highest two rating categories for such securities, and certain securities
that are not rated but are of comparable quality as determined by the Adviser.
As a matter of fundamental policy, the Fund invests its assets so that at least
80% of its annual interest income is not only exempt from regular federal income
tax, but is not considered a preference item for purposes of the federal
alternative minimum tax.

In managing the Fund, the Adviser assesses current and projected market
conditions, particularly interest rates. Based on this assessment and a separate
credit analysis, the Adviser uses gradual shifts in portfolio maturity to
respond to expected changes and selects securities that it believes offer the
most attractive risk/return trade off.

As a money market fund, the Fund invests only in money market instruments with
remaining maturities of 397 days or less that the Adviser believes present
minimal credit risk. The Fund maintains an average weighted maturity of 90 days
or less.


PRINCIPAL RISKS OF INVESTING

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

There may be economic or political changes that impact the ability of municipal
issuers to repay principal and to make interest payments on municipal
securities. Changes in the financial condition or credit rating of municipal
issuers also may adversely affect the value of the Fund's securities.

The Fund is also subject to the risk that its market segment, tax exempt money
market instruments, may underperform other fixed income market segments or the
fixed income market as a whole. For additional information about risks, see
"More Information About Risk."

PRINCIPAL INVESTMENT STRATEGIES

The Armada Money Market Fund's investment objective is to provide as high a
level of current income as is consistent with liquidity and stability of
principal. The investment objective may be changed without a shareholder vote.
The Fund invests in a variety of high quality money market securities, including
certificates of deposit and other obligations issued by domestic and foreign
banks, as well as commercial paper. Foreign government obligations are U.S.
dollar-denominated obligations (limited to commercial paper and other notes)
issued or guaranteed by a foreign government or other entity located or
organized in a foreign country that maintains a short-term foreign currency
rating in the highest short-term ratings category by the requisite number of
Nationally Recognized Statistical Rating Organizations (NRSROs). The Adviser
also invests in securities issued or guaranteed by the U.S. Government or its
agencies (government obligations) and repurchase agreements collateralized by
government obligations and issued by financial institutions such as banks and
broker-dealers. High quality money market instruments are securities that
present minimal credit risks as determined by the Adviser and generally include
securities that are rated at the time of purchase by a major rating agency in
the highest two rating categories for such securities, and certain securities
that are not rated but are of comparable quality as determined by the Adviser.

In selecting investments for the Fund, the Adviser actively buys throughout the
money market curve, laddering maturities to meet or exceed shareholder liquidity
needs while seeking the highest possible yield consistent with the Fund's risk
profile.

As a money market fund, the Fund invests only in money market instruments with
remaining maturities of 397 days or less that the Adviser believes present
minimal credit risk. The Fund maintains an average weighted maturity of 90 days
or less.

INVESTOR PROFILE
Conservative investors seeking current income through a liquid investment


PRINCIPAL INVESTMENT STRATEGIES

The Armada Government Money Market Fund's investment objective is to provide as
high a level of current income as is consistent with liquidity and stability of
principal. The investment objective may be changed without a shareholder vote.
The Fund invests exclusively in obligations issued or guaranteed as to payment
of principal and interest by the U.S. Government, its agencies and
instrumentalities and repurchase agreements. U.S. Government securities include
direct obligations of the U.S. Treasury, and obligations of certain agencies
such as GNMA and FNMA.

In managing the Fund, the Adviser actively buys throughout the money market
curve, laddering maturities to meet or exceed shareholder liquidity needs while
seeking the highest possible yield consistent with the Fund's risk profile.

As a money market fund, the Fund invests only in money market instruments with
remaining maturities of 397 days or less and maintains an average weighted
maturity of 90 days or less.


PRINCIPAL RISKS OF INVESTING

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

Although the Fund's U.S. Government securities are considered to be among the
safest investments, they are not guaranteed against price movements due to
changing interest rates. Obligations issued by some U.S. Government agencies and
instrumentalities are backed by the U.S. Treasury, while others are backed
solely by the ability of the agency to borrow from the U.S. Treasury or by the
agency's own resources.

The Fund is also subject to the risk that its market segment, money market
instruments issued or guaranteed by the U.S. Government, may underperform other
fixed income market segments or the fixed income market as a whole. For
additional information about risks, see "More Information About Risk."

                       ARMADA TREASURY MONEY MARKET FUND



FUND SUMMARY


INVESTMENT GOAL
High current income consistent with stability of principal while maintaining
liquidity


INVESTMENT FOCUS
U.S. Treasury securities


SHARE PRICE VOLATILITY
(RELATIVE TO MUTUAL FUNDS GENERALLY)
Very low


PRINCIPAL INVESTMENT STRATEGY
Investing in a portfolio of high quality short-term obligations of the U.S.
Treasury designed to allow the Fund to maintain a stable net asset value of
$1.00 per share


INVESTOR PROFILE
Conservative investors seeking current income through a liquid investment


PRINCIPAL INVESTMENT STRATEGIES

The Armada Treasury Money Market Fund's investment objective is to provide as
high a level of current income as is consistent with liquidity and stability of
principal. The investment objective may be changed without a shareholder vote.
The Fund invests exclusively in direct obligations of the U.S. Treasury, such as
Treasury bills and notes, and in other money market funds that invest
exclusively in such obligations.

In managing the Fund, the Adviser actively buys throughout the money market
curve, laddering maturities to meet or exceed shareholder liquidity needs while
seeking the highest possible yield consistent with the Fund's risk profile.

As a money market fund, the Fund invests only in money market instruments with
remaining maturities of 397 days or less and maintains an average weighted
maturity of 90 days or less.


PRINCIPAL RISKS OF INVESTING

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

The Fund is also subject to the risk that its market segment, U.S. Treasury
securities, may underperform other fixed income market segments or the fixed
income market as a whole. For additional information about risks, see "More
Information About Risk."

                           ARMADA MID CAP GROWTH FUND

FUND SUMMARY

INVESTMENT GOAL
Capital appreciation


INVESTMENT FOCUS
Mid-cap equity securities


SHARE PRICE VOLATILITY
(RELATIVE TO MUTUAL FUNDS GENERALLY)
High


PRINCIPAL INVESTMENT STRATEGY
Investing in growth-oriented equity securities of medium-sized issuers


INVESTOR PROFILE
Investors seeking capital growth, and who are willing to accept the risks of
investing in equity securities

PRINCIPAL INVESTMENT STRATEGIES

The Armada Mid Cap Growth Fund's investment objective is to provide capital
appreciation by investing in a diversified portfolio of publicly traded mid cap
equity securities. The investment objective may be changed without a shareholder
vote. The Fund will normally invest at least 80% of its total assets in the
common stock of companies with mid cap stock market capitalization. The Fund may
invest up to 20% of its total assets at the time of purchase in foreign equity
securities. In selecting investments for the Fund to buy and sell, the Adviser
invests in companies that have typically exhibited consistent, above-average
growth in revenues and earnings, strong management, sound and improving
financial fundamentals and presently exhibit the potential for growth.

The Fund considers a "mid-capitalization (mid cap)" company to be one that has a
comparable market capitalization as the companies in the Russell Mid Cap Growth
Index. The Russell MidCap Growth Index is an unmanaged index which reflects a
medium-sized universe of growth-oriented stocks.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity
securities may fluctuate from day-to-day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by such companies may decline in
response. These factors contribute to price volatility, which is the principal
risk of investing in the Fund.

Investing in foreign countries poses additional risks since political and
economic events unique to a country or region will affect those markets and
their issuers. These events will not necessarily affect the U.S. economy or
similar issuers located in the United States. In addition, investments in
foreign countries are generally denominated in a foreign currency. As a result,
changes in the value of those currencies compared to the U.S. dollar may affect
(positively or negatively) the value of a Fund's investments. These currency
movements may happen separately from and in response to events that do not
otherwise affect the value of the security in the issuer's home country.

The Fund is also subject to the risk that its market segment, mid cap equity
securities, may underperform other equity market segments or the equity market
as a whole. For additional information about risks, see "More Information About
Risk."

PRINCIPAL INVESTMENT STRATEGIES

The Armada Large Cap Ultra Fund's investment objective is to provide capital
appreciation by investing in a diversified portfolio of publicly traded larger
cap equity securities. The investment objective may be changed without a

in the common stock of companies with large market capitalizations.

The Adviser takes a long-term approach to managing the Fund and typically
invests in companies that have exhibited consistent, above-average growth in

Low


PRINCIPAL INVESTMENT STRATEGY
Investing in mortgage-related securities issued or guaranteed by the U.S.
Government


INVESTOR PROFILE
Investors seeking current income, and who are willing to accept the risks of
investing in fixed income securities

PRINCIPAL INVESTMENT STRATEGIES

The Armada U.S. Government Income Fund's investment objective is to provide
current income as well as preservation of capital by investing primarily in U.S.
Government securities. The investment objective may be changed without a
shareholder vote. The Fund invests normally at least 80% of its total assets in
obligations issued or guaranteed by the U.S. Government or its agencies or
instrumentalities. The types of U.S. Government securities include
mortgage-related securities, and Treasury bills, notes and bonds. The Fund may
invest up to 20% of the value of its total assets in mortgage-related debt
securities and preferred stock of non-governmental issuers and the same
proportion of its total assets in non-governmental asset backed securities. In
buying and selling securities for the Fund, the Adviser considers a number of
factors, including yield to maturity, maturity, quality and the outlook for
particular issuers and market sectors. The Fund generally maintains a
dollar-weighted average maturity of between three and ten years.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

The prices of the Fund's fixed income securities respond to economic
developments, particularly interest rate changes, as well as to perceptions
about the creditworthiness of individual issuers, including governments.
Generally, the Fund's fixed income securities will decrease in value if interest
rates rise and vice versa. Also, longer-term securities are generally more
volatile, so the average maturity or duration of these securities affects risk.

The Fund is also subject to the risk that its market segment, U.S. Government
securities, may underperform other fixed income market segments or the fixed
income market as a whole.

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

The mortgages underlying mortgage-backed securities may be paid off early, which
makes it difficult to determine their actual maturity and therefore calculate
how they will respond to changes in interest rates. The Fund may have to
reinvest prepaid amounts at lower interest rates. This risk of prepayment is an
additional risk of mortgage-backed securities.

Debt extension risk is the risk that an issuer will exercise its right to pay
principal on an obligation held by the Fund (such as an asset-backed security)
later than expected. This may happen during a period of rising interest rates.
Under these circumstances, the value of the obligation will decrease and the
Fund will suffer from the inability to invest in higher yielding securities.

Although the Fund's U.S. Government securities are considered to be among the
safest investments, they are not guaranteed against price movements due to
changing interest rates. Obligations issued by some U.S. Government agencies and
instrumentalities are backed by the U.S. Treasury, while others are backed
solely by the ability of the agency to borrow from the U.S. Treasury or by the
agency's own resources. For additional information about risks, see "More
Information About Risk."

FUND SUMMARY

INVESTMENT GOAL
Current income exempt from federal income tax and, to the extent possible, from
Michigan personal income tax, as is consistent with conservation of capital


INVESTMENT FOCUS
Michigan tax exempt securities


SHARE PRICE VOLATILITY
(RELATIVE TO MUTUAL FUNDS GENERALLY)
Medium


PRINCIPAL INVESTMENT STRATEGY
Investing in municipal obligations that pay interest that is exempt from federal
and Michigan state income taxes


INVESTOR PROFILE
Investors seeking tax exempt current income, and who are willing to accept
moderate share price volatility

PRINCIPAL INVESTMENT STRATEGIES

The Armada Michigan Municipal Bond Fund's investment objective is to provide
current income exempt from federal income tax and, to the extent possible, from
Michigan personal income tax, as is consistent with conservation of capital.
Such income may be subject to the federal alternative minimum tax when received
by certain shareholders. The investment objective may be changed without a
shareholder vote. The Fund invests primarily in debt securities issued by or on
behalf of the State of Michigan, its political subdivisions and its agencies and
instrumentalities that generate income exempt from federal and Michigan state
income, but may be treated as a preference item for individuals for purposes of
the federal alternative minimum tax (Michigan municipal securities). The Fund
also invests in municipal securities issued by or on behalf of territories and
possessions of the United States, the District of Columbia and their political
subdivisions, agencies, instrumentalities and authorities. In selecting
securities for the Fund to buy and sell, the Adviser considers each security's
yield and total return potential relative to other available municipal
securities. The Fund will normally invest at least 80% of the value of its total
assets in Michigan municipal securities. However, some Fund dividends will be
taxable, such as dividends that are derived from occasional taxable investments
and distributions of short and long-term capital gains. Also, Fund dividends
will generally be subject to state and local income taxes for any shareholders
who are not Michigan residents. The Fund may invest up to 100% of its total
assets in private activity bonds which may be treated as a specific tax
preference item under the federal alternative minimum tax.

The Fund invests in investment grade securities, which are those rated in one of
the four highest rating categories by a major rating agency, or determined by
the Adviser to be of equivalent quality. If a security is downgraded, the
Adviser will re-evaluate whether continuing to hold the security is in the best
interest of its shareholders. The Fund ordinarily will maintain a
dollar-weighted average portfolio maturity of between three and ten years.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

The prices of the Fund's fixed income securities respond to economic
developments, particularly interest rate changes, as well as to perceptions
about the creditworthiness of individual issuers, including governments.
Generally, the Fund's fixed income securities will decrease in value if interest
rates rise and vice versa. Also, longer-term securities are generally more
volatile, so the average maturity or duration of these securities affects risk.

The Fund is also subject to the risk that its market segment, tax free municipal
securities, may underperform other fixed income market segments or the fixed
income market as a whole.

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

There may be economic or political changes that impact the ability of municipal
issuers to repay principal and to make interest payments on municipal
securities. Changes in the financial condition or credit rating of municipal
issuers also may adversely affect the value of the Fund's securities.

               ARMADA MICHIGAN MUNICIPAL BOND FUND (CONTINUED)

PRINCIPAL RISKS OF INVESTING (continued)

The Fund's focus of investments in securities of issuers located in Michigan
subjects the Fund to economic and government policies of that state.

The Fund is non-diversified, which means that it may invest in the securities of
relatively few issuers. As a result, the Fund may be more susceptible than a
diversified fund to a single adverse economic or political and regulatory
occurrences affecting one or more of these issuers, and may experience increased
volatility due to its investments in those securities. For additional
information about risks, see "More Information About Risk."

PERFORMANCE INFORMATION

There is no bar chart or performance table for the Class A and B Shares because
they are not yet operating.

The performance of Class A and Class B Shares will differ due to differences in
expenses.

FUND SUMMARY

INVESTMENT GOAL
Current income consistent with liquidity and stability of principal


INVESTMENT FOCUS
U.S. Treasury securities and repurchase agreements related to such securities


SHARE PRICE VOLATILITY
(RELATIVE TO MUTUAL FUNDS GENERALLY)
Very low


PRINCIPAL INVESTMENT STRATEGY
Investing in a portfolio of high quality short-term obligations of the U.S.
Treasury designed to allow the Fund to maintain a stable net asset value of
$1.00 per share


INVESTOR PROFILE
Investors seeking current income through a liquid and stable investment

PRINCIPAL INVESTMENT STRATEGIES

The Armada Treasury Plus Money Market Fund's investment objective is to provide
current income with liquidity and stability of principal. The investment
objective may be changed without a shareholder vote. The Fund invests
exclusively in obligations issued or guaranteed by the U.S. Treasury and
repurchase agreements related to such securities.

In managing the Fund, the Adviser assesses current and projected market
conditions. Based on this assessment, the Adviser uses gradual shifts in
portfolio maturity to respond to expected changes and selects securities that it
believes offer the most attractive trade off between risk and return.

As a money market fund, the Fund invests only in money market instruments with
remaining maturities of 397 days or less and maintains an average weighted
maturity of 90 days or less.

PRINCIPAL RISKS OF INVESTING

The prices of the Fund's fixed income securities respond to economic
developments, particularly interest rate changes. Generally, the Fund's fixed
income securities will decrease in value if interest rates rise and vice versa.

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

Although the Fund's U.S. Treasury securities are considered to be among the
safest investments, they are not guaranteed against price movements due to
changing interest rates. Obligations issued by the U.S. Treasury are backed by
the U.S. Treasury.

The Fund is also subject to the risk that its market segment, U.S. treasury
securities, may underperform other fixed income segments or the fixed income
market as a whole. For additional information about risks, see "More Information
About Risk."

EQUITY RISK -- Equity securities include public and privately issued equity
securities, common and preferred stocks, warrants, rights to subscribe to common
stock and convertible securities, as well as instruments that attempt to track
the price movement of equity indices. Investments in equity securities and
equity derivatives in general are subject to market risks that may cause their
prices to fluctuate over time. The value of securities convertible into equity
securities, such as warrants or convertible debt, is also affected by prevailing
interest rates, the credit quality of the issuer and any call provision.
Fluctuations in the value of equity securities in which a mutual fund invests
will cause a fund's net asset value to fluctuate. An investment in a portfolio
of equity securities may be more suitable for long-term investors who can bear
the risk of these share price fluctuations.

     CONVERTIBLE SECURITIES -- Convertible securities have characteristics of
     both fixed income and equity securities. The value of the convertible
     security tends to move with the market value of the underlying stock, but
     may also be affected by interest rates, credit quality of the issuer and
     any call provisions.

FIXED INCOME RISK -- The market value of fixed income investments change in
response to interest rate changes and other factors. During periods of falling
interest rates, the values of outstanding fixed income securities generally
rise. Moreover, while securities with longer maturities tend to produce higher
yields, the prices of longer maturity securities are also subject to greater
market fluctuations as a result of changes in interest rates. In addition to
these fundamental risks, different types of fixed income securities may be
subject to the following additional risks:

     CALL RISK -- During periods of falling interest rates, certain debt
     obligations with high interest rates may be prepaid (or "called") by the
     issuer prior to maturity. This may cause a Fund's average weighted maturity
     to fluctuate, and may require a Fund to invest the resulting proceeds at
     lower interest rates.

     CREDIT RISK -- The possibility that an issuer will be unable to make timely
     payments of either principal or interest.

     EVENT RISK -- Securities may suffer declines in credit quality and market
     value due to issuer restructurings or other factors. This risk should be
     reduced because of the diversification provided by the Fund's multiple
     holdings.

     HIGH-YIELD, LOWER RATED SECURITIES (or "junk bonds") are subject to
     additional risks associated with investing in high-yield securities,
     including:

     - High-yield, lower rated securities involve greater risk of default or
       price declines than investments in investment grade securities (e.g.,
       securities rated BBB or higher by S&P or Baa or higher by Moody's) due to
       changes in the issuer's creditworthiness.

     - The market for high-yield, lower rated securities may be thinner and less
       active, causing market price volatility and limited liquidity in the
       secondary market. This may limit the ability of a Fund to sell these
       securities at their fair market values either to meet redemption
       requests, or in response to changes in the economy or the financial
       markets.

     - Market prices for high-yield, lower rated securities may also be affected
       by investors' perception of the issuer's credit quality and the outlook
       for economic growth. Thus, prices for high-yield, lower rated securities
       may move independently of interest rates and the overall bond market.

     - The market for high-yield, lower rated securities may be adversely
       affected by legislative and regulatory developments.

     MUNICIPAL ISSUER RISK -- There may be economic or political changes that
     impact the ability of municipal issuers to repay principal and to make
     interest payments on municipal securities. Changes to the financial
     condition or credit rating of municipal issuers may also adversely affect
     the value of the Fund's municipal securities. Constitutional or legislative
     limits on borrowing by municipal issuers may result in reduced supplies of
     municipal securities. Moreover, certain municipal securities are backed
     only by a municipal issuer's ability to levy and collect taxes.

     In addition, the Fund's concentration of investments in issuers located in
     a single state makes the Fund more susceptible to adverse political or
     economic developments affecting that state. The Fund also may be riskier
     than mutual funds that buy securities of issuers in numerous states.

     MORTGAGE-BACKED SECURITIES -- Mortgage-backed securities are fixed income
     securities representing an interest in a pool of underlying mortgage loans.
     They are sensitive to changes in interest rates, but may respond to these
     changes differently from other fixed income securities due to the
     possibility of prepayment of the underlying mortgage loans. As a result, it
     may not be possible to determine in advance the actual maturity date or
     average life of a mortgage-backed security. Rising interest rates tend to
     discourage refinancings, with the result that the average life and
     volatility of the security will increase exacerbating its decrease in
     market price. When interest rates fall, however, mortgage-backed securities
     may not gain as much in market value because of the expectation of
     additional mortgage prepayments that must be reinvested at lower interest
     rates. Prepayment risk may make it difficult to calculate the average
     maturity of a portfolio of mortgage-backed securities and, therefore, to
     assess the volatility risk of that portfolio.

FOREIGN SECURITY RISKS -- Investments in securities of foreign companies or
governments can be more volatile than investments in U.S. companies or
governments. Diplomatic, political, or economic developments, including
nationalization or appropriation, could affect investments in foreign countries.
Foreign securities markets generally have less trading volume and less liquidity
than U.S. markets. In addition, the value of securities denominated in foreign
currencies, and of dividends from such securities, can change significantly when
foreign currencies strengthen or weaken relative to the U.S. dollar. Foreign
companies or governments generally are not subject to uniform accounting,
auditing, and financial reporting standards comparable to those applicable to
domestic U.S. companies or governments. Transaction costs are generally higher
than those in the U.S. and expenses for custodial arrangements of foreign
securities may be somewhat greater than typical expenses for custodial
arrangements of similar U.S. securities. Investment in sovereign debt
obligations by certain Funds involves risks not present in debt obligations of
corporate issuers. The issuer of the debt or the governmental authorities that
control the repayment of the debt may be unable or unwilling to repay principal
or interest when due in accordance with the terms of such debt, and a Fund may
have limited recourse to compel payment in the event of a default. Periods of
economic uncertainty may result in volatility of market prices of sovereign
debt, and in turn a Fund's NAV, to a greater extent than the volatility inherent
in debt obligations of U.S. issuers. Some foreign governments levy withholding
taxes against dividend and interest income. Although in some countries a portion
of these taxes are recoverable, the non-recovered portion will reduce the income
received from the securities comprising the portfolio.

In addition to these risks, certain foreign securities may be subject to the
following additional risks factors:

     CURRENCY RISK -- Investments in foreign securities denominated in foreign
     currencies involve additional risks, including:

     - The value of a Fund's assets measured in U.S. dollars may be affected by
       changes in currency rates and in exchange control regulations.

     - A Fund may incur substantial costs in connection with conversions between
       various currencies.

     - A Fund may be unable to hedge against possible variations in foreign
       exchange rates or to hedge a specific security transaction or portfolio
       position.

     - Only a limited market currently exists for hedging transactions relating
       to currencies in certain emerging markets.

     HEDGING RISK -- Hedging is a strategy designed to offset investment risks.
     Hedging activities include, among other things, the use of forwards,
     options and futures. There are risks associated with hedging activities,
     including:

     - The success of a hedging strategy may depend on an ability to predict
       movements in the prices of individual securities, fluctuations in
       markets, and movements in interest and currency exchange rates.

     - There may be an imperfect or no correlation between the changes in market
       value of the securities held by the Fund or the currencies in which those
       securities are denominated and the prices of forward contracts, futures
       and options on futures.

     - There may not be a liquid secondary market for a futures contract or
       option.

     - Trading restrictions or limitations may be imposed by an exchange, and
       government regulations may restrict trading in currencies, futures
       contracts and options.

<PAGE>   81

     LEVERAGING RISK -- Leveraging activities include, among other things,
     borrowing and the use of short sales, options and futures. There are risks
     associated with leveraging activities, including:

     - A fund experiencing losses over certain ranges in the market that exceed
       losses experienced by a non-leveraged Fund.

     - There may be an imperfect or no correlation between the changes in market
       value of the securities held by a fund and the prices of futures and
       options on futures.

     - Although the funds will only purchase exchange-traded futures and
       options, due to market conditions there may not be a liquid secondary
       market for a futures contract or option. As a result, the funds may be
       unable to close out their futures or options contracts at a time which is
       advantageous.

     - Trading restrictions or limitations may be imposed by an exchange, and
       government regulations may restrict trading in futures contracts and
       options.

     In addition, the following leveraged instruments are subject to certain
     specific risks:

     DERIVATIVES RISK -- The Funds use derivatives to attempt to achieve their
     investment objectives, while at the same time maintaining liquidity. To
     collateralize (or cover) these derivatives transactions, the Funds hold
     cash or U.S. Government securities.

     FUTURES -- Futures contracts and options on futures contracts provide for
     the future sale by one party and purchase by another party of a specified
     amount of a specific security at a specified future time and at a specified
     price. An option on a futures contract gives the purchaser the right, in
     exchange for a premium, to assume a position in a futures contract at a
     specified exercise price during the term of the option. Index futures are
     futures contracts for various indices that are traded on registered
     securities exchanges.

     The Funds may use futures contracts and related options for bona fide
     hedging purposes to offset changes in the value of securities held or
     expected to be acquired. They may also be used to gain exposure to a
     particular market or instrument, to create a synthetic money market
     position, and for certain other tax-related purposes. The Funds will only
     enter into futures contracts traded on a national futures exchange or board
     of trade.

     OPTIONS -- The buyer of an option acquires the right to buy (a call option)
     or sell (a put option) a certain quantity of a security (the underlying
     security) or instrument at a certain price up to a specified point in time.
     The seller or writer of an option is obligated to sell (a call option) or
     buy (a put option) the underlying security. When writing (selling) call
     options on securities, the Funds may cover its position by owning the
     underlying security on which the option is written or by owning a call
     option on the underlying security. Alternatively, the Funds may cover its
     position by maintaining in a segregated account cash or liquid securities
     equal in value to the exercise price of the call option written by the
     Funds.

     Because option premiums paid or received by the Funds are small in relation
     to the market value of the investments underlying the options, buying and
     selling put and call options can be more speculative than investing
     directly in securities.

     SHORT SALES -- Short sales are transactions in which a Fund sells a
     security it does not own. To complete a short sale, a Fund must borrow the
     security to deliver to the buyer. The Fund is then obligated to replace the
     borrowed security by purchasing the security at the market price at the
     time of replacement. This price may be more or less than the price at which
     the security was sold by the Fund.

REAL ESTATE INVESTING -- The Fund's investments in the securities of real estate
investment trusts (REITs) and companies principally engaged in the real estate
industry may subject the Fund to the risks associated with the direct ownership
of real estate. Risks commonly associated with the direct ownership of real
estate include fluctuations in the value of underlying properties and defaults
by borrowers or tenants. In addition to these risks, REITs are dependent on
specialized management skills and some REITs may have investments in relatively
few properties, or in a small geographic area or a single type of property.
These factors may increase the volatility of the Fund's investments in REITs.

REGIONAL RISK -- To the extent that a Fund's investments are focused in a
specific geographic region, the Fund may be subject to the political and other
developments affecting that region. Regional economies are often closely
interrelated, and political and economic developments affecting one region,
country or state often affect other regions, countries or states, thus
subjecting a Fund to additional risks.

TRACKING ERROR RISK -- Factors such as Fund expenses, imperfect correlation
between the Fund's investments and those of their benchmarks, rounding of share
prices, changes to the benchmark, regulatory policies, and leverage, may affect
their ability to achieve perfect correlation. The magnitude of any tracking
error may be affected by a higher portfolio turnover rate. Because an index is
just a composite of the prices of the securities it represents rather than an
actual portfolio of those securities, an index will have no expenses. As a
result, a Fund, which will have expenses such as taxes, custody, management fees
and other operational costs, and brokerage, may not achieve its investment
objective of accurately correlating to an index.

YEAR 2000 RISK -- The Funds depend on the smooth functioning of computer systems
in almost every aspect of their business. Like other mutual funds, businesses
and individuals around the world, the Funds could be adversely affected if the
computer systems used by its service providers do not properly process dates on
and after January 1, 2000, and distinguish between the year 2000 and the year
1900. The Funds have asked their service providers whether they expect to have
their computer systems adjusted for the year 2000 transition, and is seeking
assurances from each service provider that they are devoting significant
resources to prevent material adverse consequences to the Funds. While it is
likely that such assurances will be obtained, the Funds and their shareholders
may experience losses if these assurances prove to be incorrect or as a result
of year 2000 computer difficulties experienced by issuers of portfolio
securities or third parties, such as custodians, banks, broker-dealers or others
with which the Funds do business. In addition, to the extent that the operations
of issuers of securities held by a Fund are impaired by the year 2000
transition, or prices of securities held by a Fund decline as a result of real
or perceived problems relating to the year 2000, the value of such Fund's shares
may be materially affected.

Furthermore, many foreign countries are not as prepared as the U.S. for the year
2000 transition. As a result, computer difficulties in foreign markets and with
foreign institutions as a result of the year 2000 may add to the possibility of
losses to the Funds and their shareholders.

EACH FUND'S OTHER INVESTMENTS

In addition to the investments and strategies described in this prospectus, each
Fund also may invest in other securities, use other strategies and engage in
other investment practices. These investments and strategies, as well as those
described in this prospectus, are described in detail in our Statement of
Additional Information. Of course, the Trust cannot guarantee that any Fund will
achieve its investment goal.

The investments and strategies described in this prospectus are those that we
use under normal conditions. During unusual economic, market, political or other
conditions, or for temporary defensive or liquidity purposes, each Fund (except
for the money market funds) may invest up to 100% of its assets in short-term
high quality debt instruments that would not ordinarily be consistent with a
Fund's principal investment strategies. A Fund will do so only if the Adviser or
Sub-Adviser believes that the risk of loss outweighs the opportunity for
achieving a Fund's investment objective.


INVESTMENT ADVISER, SUB-ADVISER AND INVESTMENT TEAM

The Investment Adviser makes investment decisions for the Funds and continuously
reviews, supervises and administers each Fund's respective investment program.

The Investment Adviser oversees the Sub-Adviser to ensure compliance with the
Funds' investment policies and guidelines, and monitors the Sub-Adviser's
adherence to its investment style. The Adviser pays the Sub-Adviser out of the
Investment Advisory fees it receives (described below).

The Board of Trustees of the Trust supervises the Adviser and establishes
policies that the Adviser must follow in its management activities.

National City Investment Management Company ("IMC"), with its principal offices
at 1900 East Ninth Street, Cleveland, Ohio 44114, serves as Adviser to the
Funds. On June 30, 1999, IMC had approximately $25.4 billion in assets under
management.

IMC utilizes a team approach for management of the Funds. No one person is
primarily responsible for making investment recommendations to the team. In the
case of the Armada Core Equity and the Armada Total Return Advantage Funds,
National Asset Management Corporation ("NAM") serves as Sub-Adviser and manages
these funds on a day-to-day basis; NAM selects, buys and sells the securities of
these Funds under the supervision of the Adviser and the Board of Trustees.

PURCHASING, SELLING AND EXCHANGING FUND SHARES

This section tells you how to buy, sell (sometimes called "redeem") or exchange
Class A and Class B Shares of the Funds.

The classes have different expenses and other characteristics.

      CLASS A SHARES

       - Front-end sales charge
       - 12b-1 fees
       - $500 minimum initial investment

      CLASS B SHARES

       - Contingent deferred sales charge
       - Higher 12b-1 fees
       - $500 minimum initial investment


For investors purchasing shares through a Planned Investment Program, the
minimum initial investment is $50.

Class A and Class B Shares are for individual and corporate investors.


HOW TO PURCHASE FUND SHARES

You may purchase shares directly by:

- - Mail,
- - Telephone,
- - Internet,
- - Wire, or
- - Automated Clearing House (ACH).

To purchase shares directly from us, please call 1-800-622-FUND (3863), log on
to our website at www.armadafunds.com or complete and send in the enclosed
application. Unless you arrange to pay by wire or ACH, write your check, payable
in U.S. dollars, to "Armada Funds (Fund name)." The Trust cannot accept
third-party checks, credit cards, credit card checks or cash.

To purchase shares by wire, you must indicate this option on your application.
Call 1-800-622-FUND to request a wire transfer. If you call by 4 p.m. Eastern
time, your payment will normally be wired to your bank on the next business day.
The Fund may charge a wire transfer fee. Note: Your financial institution may
charge a wire transfer fee.

BUYING OR SELLING SHARES THROUGH A FINANCIAL INTERMEDIARY

You may also buy shares through accounts with brokers and other institutions
that are authorized to place trades in Fund shares for their customers. If you
invest through an authorized institution, you will have to follow its
procedures. Your institution may charge a fee for its services, in addition to
the fees charged by the Trust. You will also generally have to address your
correspondence or questions regarding a Fund to your institution.

Your investment representative is responsible for transmitting all subscription
and redemption requests, investment information, documentation and money to the
Fund on time. Certain investment representatives have agreements with the Funds
that allow them to enter confirmed purchase or redemption orders on behalf of
clients and customers. Under this arrangement, the investment representative
must send your payment to the funds by the time they price their shares on the
following day. If your investment representative fails to do so, it may be
responsible for any resulting fees or losses.

GENERAL INFORMATION

You may purchase shares on any day that the New York Stock Exchange is open for
business (a "Business Day").

The Trust may reject any purchase order if it is determined that accepting the
order would not be in the best interests of the Fund or its shareholders.

The price per share (the offering price) will be the net asset value per share
(NAV) next determined after a Fund receives your purchase order plus, in the
case of Class A Shares, the applicable front-end sales charge. The NAV per share
of the Armada Money Market and Government Money Market Funds is calculated first
at 3:00 p.m. (Eastern time), then as of the close of trading of the New York
Stock Exchange. The NAV per share of the Armada Treasury Money Market, Tax
Exempt Money Market, Pennsylvania Tax Exempt Money Market, Ohio Municipal Money
Market and Treasury Plus Money Market Funds are calculated on each business day
first at 1:00 p.m. (Eastern time), then as of the close of trading of the New
York Stock Exchange.

Each bond and equity fund calculates its NAV once each Business Day at the
regularly-scheduled close of normal trading on the New York Stock Exchange
(normally, 4:00 p.m. (Eastern time)). So, for you to receive the current
Business Day's NAV, generally a Fund must receive your purchase order before
4:00 p.m. (Eastern time).

So, for you to be eligible to receive dividends declared on the day you submit
your purchase order, generally a

                                 82 PROSPECTUS

<PAGE>   85


Fund must receive your order before 4:00 p.m. (Eastern time) and federal funds
(readily available funds) before 2:00 p.m. (Eastern time) the following business
day.

Purchase orders for shares of the Armada Money Market and Government Money
Market Funds which are received by the Transfer Agent by 3:00 p.m. (Eastern
time) are processed that day. Purchase orders for shares of the Armada Treasury
Money Market, Tax Exempt Money Market, Pennsylvania Tax Exempt Money Market,
Ohio Municipal Money Market and Treasury Plus Money Market Funds which are
received by the Transfer Agent by 1:00 p.m. (Eastern time) are also processed
that day.

HOW WE CALCULATE NAV

NAV for one Fund share is the value of that share's portion of all of the assets
in the Fund less liabilities and class expenses.

NON-MONEY MARKET FUNDS

In calculating NAV, a non-money market fund generally values its investment
portfolio at market price. In the event that a sale of a particular fixed income
security is not reported for that day, fixed income securities are priced at the
mean between the most recent quoted bid and asked prices. Unlisted securities
and securities traded on a national securities market for which market
quotations are readily available are valued at the mean between the most recent
bid and asked prices. In the event that a sale of a particular equity security
is not reported for that day, shares are priced at the last bid quotation. If
market prices are unavailable or a Fund thinks that they are unreliable, fair
value prices may be determined in good faith using methods approved by the Board
of Trustees.

MONEY MARKET FUNDS

In calculating NAV for the money market funds, we generally value a Fund's
investment portfolio using the amortized cost valuation method, which is
described in detail in our Statement of Additional Information. If this method
is determined to be unreliable during certain market conditions or for other
reasons, a Fund may value its portfolio at market price or fair value prices may
be determined in good faith using methods approved by the Board of Trustees.

Some Funds hold securities that are listed on foreign exchanges. These
securities may trade on weekends or other days when the Funds do not calculate
NAV. As a result, the market value of these Fund's investments may change on
days when you cannot buy and hold Fund shares.

MINIMUM PURCHASES

To purchase shares for the first time, you must invest in any Fund at least:

Class                                      Dollar Amount
- -------------------------------------------------------------------------------
Class A Shares                                 $500
Class B Shares                                 $500
- -------------------------------------------------------------------------------

There is no minimum for subsequent investments.

PLANNED INVESTMENT PROGRAM

If you have a checking or savings account with a bank, you may purchase Class A
or Class B Shares automatically through regular deductions from your account in
amounts of at least $50 per month.

With a $50 minimum initial investment, you may begin regularly scheduled
investments on a monthly or quarterly basis.


SALES CHARGES

FRONT-END SALES CHARGES -- CLASS A SHARES

The offering price of Class A Shares is the NAV next calculated after a Fund
receives your request, plus the front-end sales load.

The amount of any front-end sales charge included in your offering price varies,
depending on the amount of your investment:

INTERNATIONAL EQUITY, SMALL CAP VALUE, SMALL CAP GROWTH, EQUITY GROWTH, TAX
MANAGED EQUITY, CORE EQUITY, EQUITY INCOME AND MID CAP GROWTH FUNDS

With respect to purchases of $1,000,000 or more of a Fund, the Adviser may pay
from its own funds a fee of 1% (0.25% for the Enhanced Income Fund) of the
amount invested to the financial institution placing the purchase order. A 1%
sales charge (0.25% for the Enhanced Income Fund) will be assessed against a
shareholder's fund account if its value falls below $1,000,000 due to a
redemption by the shareholder within the first year following the initial
investment of $1,000,000 or more.

WAIVER OF FRONT-END SALES CHARGE -- CLASS A SHARES

The front-end sales charge will be waived on Class A Shares purchased:

- - by Trustees and Officers of the Trust and their immediate families (spouse,
  parents, siblings, children and grandchildren);

- - by directors and retired directors of National City Corporation (NCC) or any
  of its affiliates and their immediate families, employees and retired
  employees of NCC or any of its affiliates and their immediate families and
  participants in employee benefit/retirement plans of NCC or any of its
  affiliates and their immediate families;

- - by direct transfer of rollover from a qualified plan for which affiliates of
  NCC serve as trustee or agent (or certain institutions having relationships
  with affiliates of NCC);

- - by investors purchasing through payroll deduction, investors in Armada Plus
  account through NCC's Retirement Plan Services or investors investing though
  "one stop" networks;

- - by orders placed by qualified broker-dealers, investment advisers or financial
  planners who charge a management fee for their services and place trades for
  their own account or accounts of clients; and

- - by exchanges from Parkstone B Shares to the Trust's Class A Shares or by
  exchanges from Parkstone A Shares to the Trust's Class A Shares. If sales
  charge for new shares would be greater than sales charge paid on the previous
  shares, the shareholder is responsible for paying the difference.

REPURCHASE OF CLASS A SHARES

You may repurchase any amount of Class A Shares of any Fund at NAV without the
normal front-end sales charge, up to the limit of the value of any amount of
Class A Shares (other than those which were purchased with reinvested dividends
and distributions) that you redeemed within the past 180 days. In effect, this
allows you to reacquire shares that you may have had to redeem, without
re-paying the front-end sales charge. To exercise this privilege, the Fund must
receive your purchase order within 180 days of your redemption. In addition, you
must notify the Fund when you send in your purchase order that you are
repurchasing shares.

REDUCED SALES CHARGES -- CLASS A SHARES

RIGHTS OF ACCUMULATION. In calculating the appropriate sales charge rate, this
right allows you to add the value of the Class A Shares you already own to the
amount that you are currently purchasing. The Fund will combine the value of
your current purchases with the current value of any Class A Shares you
purchased previously for (i) your account, (ii) your spouse's account, (iii) a
joint account with your spouse, or (iv) your minor children's trust or custodial
accounts. A fiduciary purchasing shares for the same fiduciary account, trust or
estate may also use this right of accumulation. The Fund will only consider the
value of Class A Shares purchased previously that were sold subject to a sales
charge. To be entitled to a reduced sales charge based on shares already owned,
you must ask us for the reduction at the time of purchase. You must provide the
Fund with your account number(s) and, if applicable, the account numbers for
your spouse and/or children (and provide the children's ages). The Fund may
amend or terminate this right of accumulation at any time.

LETTER OF INTENT. You may purchase Class A Shares at the sales charge rate
applicable to the total amount of the purchases you intend to make over a
13-month period. In other words, a Letter of Intent allows you to purchase Class
A Shares of a Fund over a 13-month period and receive the same sales charge as
if you had purchased all the shares at the same time. The Fund will only
consider the value of Class A Shares sold subject to a sales charge. As a
result, shares of the Class A Shares purchased with dividends or distributions
will not be included in the calculation. To be entitled to a reduced sales
charge based on shares you intend to purchase over the 13-month period, you must
send the Fund a Letter of Intent. In calculating the total amount of purchases
you may include in your letter purchases made up to 90 days before the date of
the Letter. The 13-month period begins on the date of the first purchase,
including those purchases made in the 90-day period before the date of the
Letter. Please note that the purchase price of these prior purchases will not be
adjusted.

If you do not purchase the amount of shares indicated in the Letter, the Letter
authorizes the Fund to hold in escrow 4% of the total amount you intend to
purchase. If you do not complete the total intended purchase at the end of the
13-month period or you redeem the entire amount within one year from the time of
fulfillment, the Fund's transfer agent will redeem the necessary portion of the
escrowed shares to make up the difference between the reduced rate sales charge
(based on the amount you intended to purchase) and the sales charge that would
normally apply (based on the actual amount you purchased).

COMBINED PURCHASE/QUANTITY DISCOUNT PRIVILEGE. When calculating the appropriate
sales charge rate, the Fund will combine same day purchases of Class A Shares
(that are subject to a sales charge) made by you, your spouse and your minor
children (under age 21). This combination also applies to Class A Shares you
purchase with a Letter of Intent. You must notify the Fund of the purchases that
qualify for this discount.

CONTINGENT DEFERRED SALES CHARGES -- CLASS B SHARES

You do not pay a sales charge when you purchase Class B Shares. The offering
price of Class B Shares is simply the next calculated NAV. But if you sell your
shares within five years after your purchase, you will pay a contingent deferred
sales charge as described in the table below for either (1) the NAV of the
shares at the time of purchase, or (2) NAV of the shares next calculated after
the Fund receives your sale request in good order, whichever is less. The sales
charge does not apply to shares you purchase through reinvestment of dividends
or distributions. So, you never pay a deferred sales charge on any increase in
your investment above the initial offering price. This sales charge does not
apply to exchanges of Class B Shares of one Fund for Class B Shares of another
Fund. After eight years, your Class B Shares are converted to Class A Shares.

When an Investor redeems his or her B shares the redemption order is processed
to minimize the amount of the contingent deferred sales charge that will be
charged. B shares are redeemed first from those B shares that are not subject to
the deferred sales load (i.e. B shares that were acquired through reinvestment
of dividends or capital gain distributions) and thereafter, unless otherwise
designated by the shareholder, from the B shares that have held the longest.

The contingent deferred sales charge will be waived if you sell your Class B
Shares for the following reasons:

- - redemptions following the death or disability of a shareholder;

- - redemptions representing a minimum required distribution from an IRA or a
  custodial account to a shareholder who has reached 701/2 years of age;

- - minimum required distributions from an IRA or a custodial account to a
  shareholder who has died or become disabled;

- - redemptions by participants in a qualified plan for retirement loans,
  financial hardship, certain participant expenses and redemptions due to
  termination of employment with plan sponsor;

- - redemptions by a settlor of a living trust;

- - redemptions effected pursuant to a Fund's right to liquidate a shareholder's
  account if the value of shares held in the account is less than the minimum
  account size;

- - return of excess contributions;

- - redemptions following the death or disability of both shareholders in the case
  of joint accounts;

- - exchanges of B Shares between funds of the Trust; and

- - distributions of less than 10% of the annual account value under a Systematic
  Withdrawal Plan.

GENERAL INFORMATION ABOUT SALES CHARGES

Your securities dealer is paid a commission when you buy your shares and is paid
a servicing fee as long as you hold your shares. Your securities dealer or
servicing agent may receive different levels of compensation depending on which
Class of shares you buy.

From time to time, some financial institutions may be reallowed up to the entire
sales charge. Firms that receive a reallowance of the entire sales charge may be
considered underwriters for the purpose of federal securities law.


HOW TO SELL YOUR FUND SHARES

Holders of Class A or B Shares may sell shares by following procedures
established when they opened their account or accounts. If you have questions,
call 1-800-622-FUND (3863).

If you own your shares through an account with a broker or other institution,
contact that broker or institution to sell your shares.

If you own your shares directly, you may sell (sometimes called "redeem") your
shares on any Business Day by contacting a Fund directly by mail, Internet
(www.armadafunds.com) or telephone at 1-800-622-FUND (3863). The minimum amount
for telephone and Internet redemptions is $100.

If you would like to sell $10,000 or more of your shares, please notify the Fund
in writing and include a signature guarantee by a bank or other financial
institution (a notarized signature is not sufficient).

The sale price of each share for redemption requests received in good order by
the Fund will be the next NAV determined less, in the case of Class B Shares,
any applicable deferred sales charge. Good order means that your request
includes complete information on your purchase, exchange or redemption and that
the Fund has received the appropriate assets.

When an Investor redeems his or her B shares, the redemption order is processed
to minimize the amount of the contingent deferred sales charge that will be
charged. B shares are redeemed first from those B shares that are not subject to
the deferred sales load (i.e., B shares that were acquired through reinvestment
of dividends or capital gain distributions) and thereafter, unless otherwise
designated by the shareholder, from the B shares that have been held the
longest.

SYSTEMATIC WITHDRAWAL PLAN

If you have at least $1,000 in your account, you may use the systematic
withdrawal plan. Under the plan you may arrange monthly, quarterly, semi-annual
or annual automatic withdrawals of at least $100 from any Fund. The proceeds of
each withdrawal will be mailed to you by check or, if you have a checking or
savings account with a bank, electronically transferred to your account. There
will be no CDSC on Investor B Shares, as long as the amounts withdrawn do not
exceed 10% annually of the account value.

RECEIVING YOUR MONEY

Normally, we will send your sale proceeds within seven days after we receive
your request. Your proceeds can be wired to your bank account or sent to you by
check. Armada Funds does not charge a fee to wire your funds; however, your
institution may charge a fee. IF YOU RECENTLY PURCHASED YOUR SHARES BY CHECK,
REDEMPTION PROCEEDS MAY NOT BE AVAILABLE UNTIL YOUR CHECK HAS CLEARED (WHICH MAY
TAKE UP TO 15 DAYS FROM YOUR DATE OF PURCHASE).

REDEMPTIONS IN KIND

We generally pay sale (redemption) proceeds in cash. However, under unusual
conditions that make the payment of cash unwise (and for the protection of the
Fund's remaining shareholders) we might pay all or part of your redemption
proceeds in liquid securities with a market value equal to the redemption price
(redemption in kind). It is highly unlikely that your shares would ever be
redeemed in kind, but if they were you would probably have to pay transaction
costs to sell the securities distributed to you, as well as taxes on any capital
gains from the sale as with any redemption. The Armada Tax Managed Equity Fund
may fund redemptions of $1 million or more with appreciated securities rather
than cash.

INVOLUNTARY SALES OF YOUR SHARES

If your account balance drops below $500 because of redemptions, you may be
required to sell your shares. But, we will always give you at least 60 days'
written notice to give you time to add to your account and avoid the sale of
your shares.

SUSPENSION OF YOUR RIGHT TO SELL YOUR SHARES

The Fund may suspend your right to sell your shares if the New York Stock
Exchange restricts trading, the SEC declares an emergency or for other reasons.
More information about this is in our Statement of Additional Information.


HOW TO EXCHANGE YOUR SHARES

You may exchange your shares on any Business Day by contacting us directly by
mail, Internet or telephone.

You may also exchange shares through your financial institution by mail or
telephone. Exchange requests must be for an amount of at least $500.

The exchange privilege is a convenient way to respond to changes in investment
goals or in market conditions. This privilege is not designed for market-timing
- - switching money into investments in anticipation of rising prices or taking
money out in anticipation of the market falling. As money is shifted in and out,
a fund incurs expenses for buying and selling securities. These costs are borne
by all fund shareholders, including the long-term investors who do not generate
the costs. Therefore, the Fund discourages short-term trading by, among other
things, limiting the number of exchanges to one exchange every two months during
a given 12-month period beginning upon the date of the first exchange
transaction. Management of the Trust reserves the right to limit, amend or
impose charges upon, terminate or otherwise modify the exchange privilege. You
will be provided 60 days' notice before any material action is taken.

IF YOU RECENTLY PURCHASED SHARES BY CHECK, YOU MAY NOT BE ABLE TO EXCHANGE YOUR
SHARES UNTIL YOUR CHECK HAS CLEARED (WHICH MAY TAKE UP TO 15 DAYS FROM YOUR DATE
OF PURCHASE).

When you exchange shares, you are really selling your shares and buying other
Fund shares. So, your sale price and purchase price will be based on the NAV
next calculated after the Fund receives your exchange request.

CLASS A SHARES

You may exchange Class A Shares of any Fund for Class A Shares of any other
Fund. If you exchange shares that you purchased without a sales charge or with a
lower sales charge into a Fund with a sales charge or with a higher sales
charge, the exchange is subject to an incremental sales charge (e.g., the
difference between the lower and higher applicable sales charges). If you
exchange shares into a Fund with the same, lower or no sales charge there is no
incremental sales charge for the exchange.

CLASS B SHARES

You may exchange Class B Shares of any Fund for Class B Shares of any other
Fund. No contingent deferred sales charge is imposed on redemptions of shares
you acquire in an exchange, provided you hold your shares for at least five
years from your initial purchase.

TELEPHONE AND INTERNET TRANSACTIONS

Purchasing, selling and exchanging Fund shares over the telephone or online is
extremely convenient, but not without risk. Although the Trust has certain
safeguards and procedures to confirm the authenticity of instructions, the Trust
is not responsible for any losses or costs incurred by following telephone or
on-line instructions we reasonably believe to be genuine. If you or your
financial institution transact with the Fund over the telephone or on-line, you
will generally bear the risk of any loss.

DISTRIBUTION OF FUND SHARES

Each Fund has adopted a distribution plan under Rule 12b-1, pursuant to the 1940
Act, as amended that allows each Fund to pay distribution and service fees for
the sale and distribution of its shares, and for services provided to
shareholders. Because these fees are paid out of a Fund's assets continuously,
over time these fees will increase the cost of your investment and may cost you
more than paying other types of sales charges.

Distribution fees, as a percentage of average daily net assets are as follows:

* As of the printing of this prospectus, these Funds have not yet commenced
operations.

Each Fund makes distributions of capital gains, if any, at least annually. If
you own Fund shares on a Fund's record date, you will be entitled to receive the
distribution.

You will receive dividends and distributions in the form of additional Fund
shares unless you elect to receive payment in cash. To elect cash payment, you
must notify the Fund in writing prior to the date of the distribution.

Your election will be effective for dividends and distributions paid after the
Fund receives your written notice. To cancel your election, simply send the Fund
written notice.

FEDERAL TAXES

Each Fund contemplates declaring as dividends each year all or substantially all
of its taxable income, including its net capital gain (the excess of long-term
capital gain over short-term capital loss). Distributions attributable to the
net capital gain of a Fund will be taxable to you as long-term capital gain,
regardless of how long you have held your shares. Other Fund distributions
(other than exempt-interest dividends, discussed below) will generally be
taxable as ordinary income. You will be subject to income tax on Fund
distributions regardless of whether they are paid in cash or reinvested in
additional shares. You will be notified annually of the tax status of
distributions to you.

In the case of any Fund other than a money-market Fund, you should note that if
you purchase shares just before a distribution, the purchase price will reflect
the amount of the upcoming distribution, but you will be taxable on the entire
amount of the distribution received, even though, as an economic matter, the
distribution simply constitutes a return of capital. This is known as "buying
into a dividend."

You will recognize taxable gain or loss on a sale, exchange or redemption of
your shares, including an exchange for shares of another Fund (or an in-kind
redemption), based on the difference between your tax basis in the shares and
the amount you receive for them. (To aid in computing your tax basis, you
generally should retain your account statements for the periods during which you
held shares.) Any loss realized on shares held for six months or less will be
treated as a long-term capital loss to the extent of any capital gain dividends
that were received on the shares.

The one major exception to these tax principles is that distributions on, and
sales, exchanges and redemptions of, shares held in an IRA (or other
tax-qualified plan) will not be currently taxable.

It is expected that the Armada International Equity Fund will be subject to
foreign withholding taxes with respect to dividends or interest received from
sources in foreign countries. The Armada International Equity Fund may make an
election to treat a proportionate amount of such taxes as constituting a
distribution to each shareholder, which would allow each shareholder either (1)
to credit such proportionate amount of taxes against U.S. federal income tax
liability or (2) to take such amount as an itemized deduction.

The Armada Tax Exempt Money Market Fund, Armada Pennsylvania Tax Exempt Money
Market Fund, Armada Ohio Municipal Money Market Fund, Armada Ohio Tax Exempt
Bond Fund, Armada Pennsylvania Municipal Bond Fund, Armada National Tax Exempt
Bond Fund, and Armada Michigan Municipal Bond Fund (the "Tax exempt Funds")
anticipate that substantially all of their income dividends will be "exempt
interest dividends," which are exempt from federal income taxes. However, some
dividends will be taxable, such as dividends that are derived from occasional
taxable investments, and in the case of other than money market Funds,
distributions of short and long-term capital gains. Interest on indebtedness
incurred by a shareholder to purchase or carry shares of any Tax exempt Fund
generally will not be deductible for federal income tax purposes.

You should note that a portion of the exempt-interest dividends paid by the Tax
Exempt Funds may constitute an item of tax preference for purposes of
determining federal alternative minimum tax liability. Exempt-interest dividends
will also be considered along with other adjusted gross income in determining
whether any Social Security or railroad retirement payments received by you are
subject to federal income taxes.

If you receive an exempt-interest dividend with respect to any share and the
share is held by you for six months or less, any loss on the sale or exchange of
the share will be disallowed to the extent of such dividend amount.

The foregoing is only a summary of certain tax considerations under current law,
which may be subject to change in the future. Shareholders who are nonresident
aliens, foreign trusts or estates, or foreign corporations or partnerships, may
be subject to different United States federal income tax treatment. You should
consult your tax adviser for further information regarding federal, state, local
and/or foreign tax consequences relevant to your specific situation.

STATE AND LOCAL TAXES

Shareowners may also be subject to state and local taxes on distributions and
redemptions. State income taxes may not apply, however, to the portions of each
Fund's distributions, if any, that are attributable to interest on federal
Securities or interest on securities of the particular state or localities
within the state. The Armada Pennsylvania Tax Exempt Money Market Fund and
Armada Pennsylvania Municipal Bond Fund intend to distribute income that is
exempt from Pennsylvania personal income taxes. The Armada Ohio Tax Exempt Bond
Fund and Armada Ohio Municipal Money Market Fund intend to distribute income
that is exempt from Ohio personal income taxes. The Armada Michigan Municipal
Bond Fund intends to distribute income that is exempt from Michigan income
taxes. Shareowners should consult their tax advisers regarding the tax status of
distributions in their state and locality.

Each Fund may invest a portion of its assets in securities that generate taxable
income for federal or state income taxes. Income exempt from federal tax may be
subject to state and local taxes. Any capital gains distributed by these Funds
may be taxable.

The Funds use a tax management technique known as "highest in, first out." Using
this technique, the portfolio holdings that have experienced the smallest gain
or largest loss are sold first in an effort to minimize capital gains and
enhance after-tax returns.

MORE INFORMATION ABOUT TAXES IS IN THE STATEMENT OF ADDITIONAL INFORMATION.

INTRODUCTION

Each Fund is a mutual fund. A mutual fund pools shareholders' money and, using
professional investment managers, invests it in securities.

Fund performance is measured against an index. An index measures the market
prices of a specific group of securities in a particular market or securities in
a market sector. You cannot invest directly in an index. Unlike a mutual fund,
an index does not have an investment adviser and does not pay any commissions or
expenses. If an index had expenses, its performance would be lower.

RISK/RETURN SUMMARY

Each Fund has its own investment goal and strategies for reaching that goal. The
investment managers invest Fund assets in a way that they believe will help a
Fund achieve its goal. Still, investing in each Fund involves risk and there is
no guarantee that a Fund will achieve its goal. An investment manager's
judgments about the markets, the economy, or companies may not anticipate actual
market movements, economic conditions or company performance, and these
judgments may affect the return on your investment.

No matter how good a job an investment manager does, you could lose money on
your investment in a Fund, just as you could with other investments.

An investment in a Fund is not a bank deposit and it is not insured or
guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any government
agency.

Although a money market fund seeks to keep a constant price per share of $1.00,
there is no guarantee that a money market fund will achieve this goal and it is
possible that you may lose money by investing in the fund.

The value of your investment in a Fund (other than a money market fund) is based
primarily on the market value of the securities the Fund holds. These prices
change daily due to economic and other events that affect particular companies
and other issuers. These price movements, sometimes called volatility, may be
greater or lesser depending on the types of securities a Fund owns and the
markets in which they trade. The effect on a Fund of a change in the value of a
single security will depend on how widely the Fund diversifies its holdings.

The Armada International Equity Fund's investment objective is to provide
capital appreciation by investing in a portfolio of equity securities of foreign
issuers. Equity securities of foreign issuers includes common stock, preferred
stock and convertible bonds, of companies headquartered outside the United
States. The investment objective may be changed without a shareholder vote. The
Fund will normally invest at least 80% of its total assets in the equity
securities of foreign issuers. The Fund focuses on issuers included in the
Morgan Stanley Capital International Europe, Australasia, Far East (World EAFE)
Index. The World EAFE is an unmanaged index which represents the performance of
more than 1,000 equity securities of companies located in those regions. The
Adviser makes judgements about the attractiveness of countries based upon a
collection of criteria. The relative valuation, growth prospects, fiscal,
monetary and regulatory government policies are considered jointly and generally
in making these judgements. The percentage of the Fund in each country is
determined by its relative attractiveness and weight in the World EAFE Index.
More than 25% of the Fund's assets may be invested in the equity securities of
issuers located in the same country. Within foreign markets, the Adviser buys
and sells securities based on its analysis of competitive position and
valuation. The adviser sells securities whose competitive position is
deteriorating or whose valuation is unattractive relative to industry peers.
Likewise, companies with strong and durable competitive advantages and
attractive valuation are considered for purchase.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity
securities may fluctuate from day-to-day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by such companies may decline in
response. These factors contribute to price volatility, which is the principal
risk of investing in the Fund.

Investing in foreign countries poses additional risks since political and
economic events unique to a country or region will affect those markets and
their issuers. These events will not necessarily affect the U.S. economy or
similar issuers located in the United States. In addition, investments in
foreign countries are generally denominated in a foreign currency. As a result,
changes in the value of those currencies compared to the U.S. dollar may affect
(positively or negatively) the value of a Fund's investments. These currency
movements may happen separately from and in response to events that do not
otherwise affect the value of the security in the issuer's home country.

Companies making up the World EAFE Index are generally issuers of larger cap
securities of multi-national companies who are affected by risks worldwide.

Investment in a particular country of 25% or more of the Fund's total assets
will make the Fund's performance more dependent upon the political and economic
circumstances of that country than a mutual fund more widely diversified among
issuers in different countries.

The Fund is also subject to the risk that its market segment, international
equity securities, may underperform other equity market segments or the equity
market as a whole. For additional information about risks, see "More Information
About Risk."

PRINCIPAL INVESTMENT STRATEGIES

The Armada Small Cap Value Fund's investment objective is to provide capital
appreciation by investing in a diversified portfolio of publicly traded small
cap equity securities. The investment objective may be changed without a
shareholder vote. The Fund will normally invest at least 80% of its total assets
in the common stocks of small capitalization companies. The Fund may invest up
to 20% of its total assets at the time of purchase in foreign equity securities.
In buying and selling securities for the Fund, the Adviser uses a value-oriented
approach. The Adviser generally seeks to invest in equity securities based upon
price/earnings, price/book and price/cash flow ratios which are lower than the
market averages. The Adviser generally sells securities based upon
price/earnings, price/book and price/cash flow ratios which rise above market
averages or when a company no longer has a small capitalization.

The Fund considers a small capitalization or "small cap" company to be one that
has a comparable market capitalization to the companies in the Russell 2000
Value Index. The Russell 2000 Value Index is an unmanaged index comprised of
securities in the Russell 2000 Index which have less than average growth
orientation.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may increase transaction costs and capital gains tax liabilities, and will
lower Fund performance.

PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity
securities may fluctuate from day-to-day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by such companies may decline in
response. These factors contribute to price volatility, which is the principal
risk of investing in the Fund.

Smaller capitalization companies may be more vulnerable to adverse business or
economic events than larger, more established companies. In particular, these
companies may have limited product lines, markets and financial resources, and
may depend upon a relatively small management group. Therefore, small cap stocks
may be more volatile than those of larger companies. These securities may be
traded over-the-counter or listed on an exchange and may or may not pay
dividends.

Investing in foreign countries poses additional risks since political and
economic events unique to a country or region will affect those markets and
their issuers. These events will not necessarily affect the U.S. economy or
similar issuers located in the United States. In addition, investments in
foreign countries are generally denominated in a foreign currency. As a result,
changes in the value of those currencies compared to the U.S. dollar may affect
(positively or negatively) the value of a Fund's investments. These currency
movements may happen separately from and in response to events that do not
otherwise affect the value of the security in the issuer's home country.

The Fund is also subject to the risk that its market segment, small cap equity
securities, may underperform other equity market segments or the equity market
as a whole. For additional information about risks, see "More Information About
Risk."

PRINCIPAL INVESTMENT STRATEGIES

The Armada Small Cap Growth Fund's investment objective is to provide capital
appreciation by investing in a diversified portfolio of publicly traded small
cap equity securities. The investment objective may be changed without a
shareholder vote. The Fund normally invests at least 80% of its total assets in
the common stocks of companies with small stock market capitalizations. The Fund
may invest up to 20% of its total assets at the time of purchase in foreign
equity securities. The Adviser seeks to invest in small capitalization companies
with strong growth in revenue, earnings, and cash flow. Purchase decisions are
also based on the security's valuation relative to the company's expected growth
rate, earnings quality and competitive position, valuation compared to similar
securities and the security's trading liquidity. Reasons for selling securities
include disappointing fundamentals, negative industry developments, evidence of
management's inability to execute a sound business plan, capitalization
exceeding the Adviser's definition of "small capitalization," desire to reduce
exposure to an industry or sector, and valuation levels which cannot be
justified by the company's fundamental growth prospects.

The Fund considers a small capitalization or "small cap" company to be one that
has a comparable market capitalization to the companies in the Russell 2000
Growth Index. The Russell 2000 Growth Index is an unmanaged index comprised of
securities in the Russell 2000 Index which have less than average growth

Due to its investment strategy, the Fund may buy and sell securities frequently.

The smaller capitalization companies the Fund invests in may be more vulnerable

PRINCIPAL INVESTMENT STRATEGIES

The Armada Equity Growth Fund's investment objective is to provide capital
appreciation by investing in a diversified portfolio of publicly traded larger
cap equity securities. The investment objective may be changed without
shareholder vote. The Fund will normally invest at least 80% of its total assets
in a diversified portfolio of common stocks and securities convertible into
common stocks of companies with large stock market capitalization. The Fund may
invest up to 20% of its total assets at the time of purchase in foreign equity
securities. In buying and selling securities for the Fund, the Adviser considers
factors such as historical and projected earnings growth, earnings quality and
liquidity. The Fund generally purchases common stocks that are listed on a
national securities exchange or unlisted securities with an established
over-the-counter market.

The Fund considers a large capitalization or "large cap" company to be one
that has a comparable market capitalization to the companies in the S&P 500
Composite Index. The S&P 500 Composite Index is a widely recognized, unmanaged
index of 500 common stocks which are generally representative of the U.S. stock
market as a whole.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity
securities may fluctuate from day-to-day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and

invest $10,000 in the Fund for the time periods indicated.

The Example also assumes that each year your investment has a 5% return and Fund
expenses remain the same. Although your actual costs and returns might be
different, your approximate costs of investing $10,000 in the Fund would be:

INVESTOR PROFILE
Investors who are seeking capital appreciation while minimizing the impact of
taxes and who are willing to accept the risk of investing in equity securities


PRINCIPAL INVESTMENT STRATEGIES

The Armada Tax Managed Equity Fund's investment objective is to provide capital
appreciation while minimizing the impact of taxes on shareholders' returns. The
investment objective may be changed without a shareholder vote. The Fund
normally invests at least 80% of its total assets in common stocks. The Fund may
invest up to 20% of its total assets at the time of purchase in foreign equity
securities. Equity securities of foreign issuers include common, preferred and
convertible bonds, of companies headquartered outside the United States. The
Adviser buys and sells common stocks based on factors such as historical and
projected long-term earnings growth, earnings quality and liquidity. The Adviser
attempts to minimize the realization of taxable gains by investing in the
securities of companies with above average earnings predictability and stability
which the Fund expects to hold for several years. This generally results in a
low level of portfolio turnover. In addition, the Fund seeks to distribute
relatively low levels of taxable investment income by investing in stocks with
low dividend yields. When the Fund sells appreciated securities, it will attempt
to select the share lots with the highest cost basis in order to hold realized
capital gains to a minimum. The Fund may, when consistent with its overall
investment approach, sell depreciated securities to offset realized capital
gains. The Fund may make in-kind redemptions consistent with its investment
objective. An in-kind redemption may serve to minimize any tax impact on the
remaining shareholders, because the Fund generally recognizes no taxable gain
(or loss) on the securities used to make an in-kind redemption. The Fund is not
a tax exempt fund, and it expects to distribute taxable dividends and capital
gains from time to time.

PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity
securities may fluctuate from day-to-day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by such companies may decline in
response. These factors contribute to price volatility, which is the principal
risk of investing in the Fund.

Investing in foreign countries poses additional risks since political and
economic events unique to a country or region will affect those markets and
their issuers. These events will not necessarily affect the U.S. economy or
similar issuers located in the United States. In addition, investments in
foreign countries are generally denominated in a foreign currency. As a result,
changes in the value of those currencies compared to the U.S. dollar may affect
(positively or negatively) the value of a Fund's investments. These currency
movements may happen separately from and in response to events that do not
otherwise affect the value of the security in the issuer's home country. For
additional information about risks, see "More Information About Risk."

The performance of the Armada Tax Managed Equity Fund for the period prior to
April 9, 1998 is represented by the performance of a common trust fund ("common
trust fund") which operated prior to the effectiveness of the registration
statement of the Tax Managed Equity Fund. The common trust fund was advised by
National City Bank, an affiliate of the Adviser. At the time of the Tax Managed
Equity Fund's inception, the common trust fund was operated using materially
equivalent investment objectives, policies, guidelines and restrictions as the
Fund. In connection with the Tax Managed Equity Fund's commencement of
operations, on April 9 1998, the common trust fund transferred its assets to the
Fund. At the time of the transfer, the Adviser did not manage any other
collective investment or common trust funds using materially equivalent
investment objectives, policies, guidelines and restrictions to those of the Tax
Managed Equity Fund. The common trust fund was not open to the public generally,
nor registered under the Investment Company Act of 1940 (the "1940 Act") or
subject to certain restrictions that are imposed by the 1940 Act and the
Internal Revenue Code. If the common trust fund had been registered under the
1940 Act, performance may have been adversely affected. Performance quotations
of the common trust fund represent past performance of the Adviser managed
common trust fund, which are separate and distinct from the Tax Managed Equity
Fund; do not represent past performance of the Fund; and should not be
considered as representative of future results of the Fund.

INVESTOR PROFILE
Investors seeking capital appreciation, who are willing to accept the risk of
investing in equity securities


PRINCIPAL INVESTMENT STRATEGIES

The Armada Core Equity Fund's investment objective is to provide capital
appreciation by blending value and growth investment styles. The investment
objective may be changed without a shareholder vote. The Fund normally invests
at least 80% of its total assets in a diversified portfolio of common stocks and
securities convertible into common stocks of companies with large stock market
capitalizations. The Sub-Adviser will normally invest between 20% and 50% of its
assets in the following three types of equity securities: (1) common stocks that
meet the Sub-Adviser's criteria for five-year annual earnings-per-share growth
rates and which exhibit no decline in the normalized annual earnings-per-share
rate during the last five years; (2) common stocks with price-to-earnings ratios
below the average of the companies included in the S&P 500 Composite Index; and
(3) common stocks that pay dividends at a rate above the average of the
companies included in the S&P 500 Composite Index.

The Sub-Adviser utilizes a systematic, disciplined investment process when
selecting individual securities. This includes: (1) screening a database for
liquidity and the criteria listed above; (2) scoring each issue emphasizing
fundamental, valuation and technical indicators; and (3) security analysis that
further evaluates the company and the stock, which includes an analysis of
company fundamentals such as earnings, profitability and management, valuation
such as price/earnings, price/book and yield, and technical analysis emphasizing
individual stock price trends.

The sell discipline involves the monitoring of each company's fundamental,
valuation, and technical measures. If one of these measures is unfavorable, an
immediate review of that company is performed. If two of these three measures
are unfavorable, that stock is sold. The Fund may invest up to 20% of its total
assets at the time of purchase in foreign equity securities.

The Fund considers a large capitalization or "large cap" company to be one that
has a comparable market capitalization to the companies in the S&P 500 Composite
Index. The S&P 500 Composite Index is a widely recognized, unmanaged index of
500 common stocks which are generally representative of the U.S. stock market as
a whole.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity

INVESTOR PROFILE
Investors seeking returns similar to the S&P 500 Composite Index, who are

PRINCIPAL INVESTMENT STRATEGIES

The Armada Equity Index Fund's investment objective is to provide investment
results that, before Fund expenses, approximate the aggregate price and dividend
performance of the securities included in the S&P 500 Composite Index by
investing in securities comprising the S&P 500 Composite Index. The investment
objective may be changed without a shareholder vote. The S&P 500 Composite Index
is made up of common stocks of 500 large, publicly traded companies. The Fund
buys and holds all stocks included in the S&P 500 Composite Index in exactly the
same proportion as those stocks are held in the Index. Stocks are eliminated
from the Fund when removed from the S&P 500 Composite Index. The Adviser makes
no attempt to "manage" the Fund in the traditional sense (i.e., by using
economic, financial or market analyses).

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity
securities may fluctuate from day-to-day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by such companies may decline in
response. These factors contribute to price volatility, which is the principal
risk of investing in the Fund.

The Fund is also subject to the risk that its market segment, the S&P 500
Composite Index of common stocks, may underperform other equity market segments
or the equity market as a whole.

The Fund's ability to duplicate the performance of the S&P 500 Composite Index
will depend to some extent on the size and timing of cash flows into and out of
the Fund, as well as on the level of the Fund's expenses. For additional
information about risks, see "More Information About Risk."

INVESTOR PROFILE
Investors seeking an income component as well as capital appreciation and who
are willing to accept the risk of investing in equity securities

PRINCIPAL INVESTMENT STRATEGIES

The Armada Equity Income Fund's investment objective is to provide capital
appreciation by investing in a diversified portfolio of publicly traded equity
securities which, in the aggregate, provide a premium current yield. Equity
securities include public and privately issued equity securities, common and
preferred stocks, warrants, rights to subscribe to common stock and convertible
securities, as well as instruments that attempt to track the price movement of
equity indices. The investment objective may be changed without a shareholder
vote.

The Fund normally invests at least 80% of its total assets in common stocks and
securities convertible into common stocks of companies that have the ability to
pay dividends with a yield above the s&p 500 composite index. The Fund May
invest up to 20% of its total assets at the time of purchase in foreign equity
securities. In buying and selling securities for the Fund, the Adviser
Emphasizes equity securities and convertible securities that provide a higher
yield than the general market. The Fund will generally sell securities when
their yields approach a market yield or they otherwise fail to satisfy
investment criteria.

Due to its investment strategy, the Fund may buy and sell
securities frequently. This may result in higher transaction costs and
additional capital gains tax liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity
securities may fluctuate from day-to-day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by such companies may decline in
response. These factors contribute to price volatility, which is the principal
risk of investing in the Fund.

Investing in foreign countries poses additional risks since political and
economic events unique to a country or region will affect those markets and
their issuers. These events will not necessarily affect the U.S. economy or
similar issuers located in the United States. In addition, investments in
foreign countries are generally denominated in a foreign currency. As a result,
changes in the value of those currencies compared to the U.S. dollar may affect
(positively or negatively) the value of a Fund's investments. These currency
movements may happen separately from and in response to events that do not
otherwise affect the value of the security in the issuer's home country.

The Fund is also subject to the risk that its market segment, income producing
equity securities, may underperform other equity market segments or the equity

A combination of growth-oriented common stocks, fixed income securities and cash

(RELATIVE TO MUTUAL FUNDS GENERALLY)
Medium

PRINCIPAL INVESTMENT STRATEGY
Investing in a diversified portfolio of growth-oriented common stocks,
investment grade fixed income securities and cash equivalents with varying asset
allocations depending on the Adviser's assessment of market conditions

INVESTOR PROFILE
Investors seeking a broad diversification by asset class and style to manage
risk and provide the potential for above-average total returns (as gauged by the
returns of the S&P 500 Composite Index and the Lehman Brothers Aggregate Bond
Index)

PRINCIPAL INVESTMENT STRATEGIES

The Armada Balanced Allocation Fund's investment objective is to provide
long-term capital appreciation and current income. The investment objective may
be changed without a shareholder vote. The Fund intends to invest 50% to 70% of
its net assets in common stocks and convertible securities, 25% to 55% of its
net assets in investment grade fixed income securities such as corporate bonds
and U.S. Government securities, and up to 30% of its net assets in cash and cash
equivalent securities (which include common stock, preferred stock and
convertible bonds of companies head-quartered outside the United States). The
Fund may invest up to 20% of its total assets at the time of purchase in foreign
securities (which include common stock, preferred stock and convertible bonds of
companies headquartered outside the United States). The Fund also invests in the
common stock of small capitalization companies. The Adviser buys and sells
equity securities based on their potential for long-term capital appreciation.
The Fund invests the fixed income portion of its portfolio of investments in a
broad range of investment grade debt securities (which are those rated at the
time of investment in one of the four highest rating categories by a major
rating agency) for current income. If a fixed income security is downgraded, the
Adviser will re-evaluate the holding to determine whether it is in the best
interests of investors to sell. The Adviser buys and sells fixed income
securities and cash equivalents based on a number of factors, including yield to
maturity, quality and the outlook for particular issuers and market sectors. The
Fund invests in cash equivalent, short-term obligations for stability and
liquidity.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity
securities may fluctuate from day-to-day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by such companies may decline in
response. These factors contribute to price volatility, which is the principal
risk of investing in the Fund.

The prices of the Fund's fixed income securities respond to economic
developments, particularly interest rate changes, as well as to perceptions
about the creditworthiness of individual issuers, including governments.
Generally, the Fund's fixed income securities will decrease in value if interest
rates rise and vice versa, and the volatility of lower rated securities is even
greater than that of higher rated securities. Also, longer-term securities are
generally more volatile, so the average maturity or duration of these securities
affects risk.

The Fund is also subject to the risk that the Adviser's asset allocation
decisions will not anticipate market trends successfully. For example, weighting
common stocks too heavily during a stock market decline may result in a failure
to preserve capital. Conversely, investing too heavily in fixed income
securities during a period of stock market appreciation may result in lower
total return.

The smaller capitalization companies the Fund invests in may be more vulnerable
to adverse business or economic events than larger, more established companies.
In particular, these small companies may have limited product lines, markets and
financial resources, and may depend upon a relatively small management group.
Therefore, small cap stocks may be more volatile than those of larger companies

may. These securities may be traded over-the-counter or listed on an exchange
and may or may not pay dividends.

Investing in foreign countries poses additional risks since political
and economic events unique to a country or region will affect those markets and
their issuers. These events will not necessarily affect the U.S. economy or
similar issuers located in the United States. In addition, investments in
foreign countries are generally denominated in a foreign currency. As a result,
changes in the value of those currencies compared to the U.S. dollar may affect
(positively or negatively) the value of a Fund's investments. These currency
movements may happen separately from and in response to events that do not
otherwise affect the value of the security in the issuer's home country.

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

Although the Fund's U.S. Government securities are considered to be among the
safest investments, they are not guaranteed against price movements due to
changing interest rates. Obligations issued by some U.S. Government agencies and
instrumentalities are backed by the U.S. Treasury, while others are backed
solely by the ability of the agency to borrow from the U.S. Treasury or by the
agency's own resources.

The Fund is also subject to the risk that its market segments, investment grade
fixed income and growth-oriented equity securities, may underperform other fixed
income or equity market segments or the fixed income or equity markets as a
whole. For additional information about risks, see "More Information About
Risk."

PRINCIPAL INVESTMENT STRATEGIES

The Armada Total Return Advantage Fund's investment objective is to provide
current income as well as preservation of capital by investing primarily in a
portfolio of high and medium-grade fixed income securities. The investment
objective may be changed without a shareholder vote. The Fund normally invests
at least 80% of the value of its total assets in investment grade fixed income
securities of all types, including asset-backed securities and mortgage-backed
securities and obligations of corporate and U.S. Government issuers. Corporate
obligations may include bonds, notes and debentures. U.S. Government securities
may include U.S. Treasury obligations and obligations of certain U.S. Government
agencies or instrumentalities. Fixed income securities are designed to provide a
fixed rate of interest at maturity and return the principal value at the end of
the term. High and medium-grade fixed income securities are those rated in one
of the four highest rating categories by a major rating agency, or determined by
the Adviser to be of equivalent quality. If a security is downgraded, the
Adviser will re-evaluate whether continuing to hold the security is in the best
interest of shareholders. In buying and selling securities for the Fund, the
Adviser uses a number of strategies, including duration/maturity management,
sector allocation and individual security selection. The Fund may invest up to
15% of its assets in fixed income securities that are non-rated or rated below
investment grade, sometimes known as "junk bonds." The Fund does not intend to
invest in junk bonds rated below C.

The Fund generally maintains an average dollar-weighted maturity of between four
and twelve years.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.

PRINCIPAL RISKS OF INVESTING

The prices of the Fund's fixed income securities respond to economic
developments, particularly interest rate changes, as well as to perceptions
about the creditworthiness of individual issuers, including governments.
Generally, the Fund's fixed income securities will decrease in value if interest
rates rise and vice versa, and the volatility of lower rated securities is even
greater than that of higher rated securities. Also, longer-term securities are
generally more volatile, so the average maturity or duration of these securities
affects risk.

Junk bonds involve greater risks of default or downgrade and are more volatile
than investment grade securities. Junk bonds involve greater risk of default or
price declines than investment grade securities due to actual or perceived
changes in an issuer's creditworthiness. In addition, issuers of junk bonds may
be more susceptible than other issuers to economic downturns. Junk bonds are
subject to the risk that the issuer may not be able to pay interest or dividends
on a timely basis and ultimately to repay principal upon maturity.
Discontinuation of these payments could substantially adversely affect the
market value of the security.

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

The mortgages underlying mortgage-backed securities may be paid off early, which
makes it difficult to determine their actual maturity and therefore calculate
how they will respond to changes in interest rates. The Fund may have to
reinvest prepaid amounts at lower interest rates. This risk of prepayment is an
additional risk of mortgage-backed securities.

Debt extension risk is the risk that an issuer will exercise its right to pay
principal on an obligation held by the Fund (such as an asset-backed security)
later than expected. This may happen during a period of rising interest rates.
Under these circumstances, the value of the obligation will decrease and the
Fund will suffer from the inability to invest in higher yielding securities.

Although the Fund's U.S. Government securities are considered to be among the
safest investments, they are not guaranteed against price movements due to

instrumentalities are backed by the full faith and credit of the United States,
while others are backed solely by the ability of the agency to borrow from the
U.S. Treasury or by the agency's own resources.

investing in fixed income securities


PRINCIPAL INVESTMENT STRATEGIES

The Armada Intermediate Bond Fund's investment objective is to provide current
income as well as preservation of capital by investing in a portfolio of high
and medium-grade fixed income securities. The investment objective may be
changed without a shareholder vote. The Fund normally invests at least 80% of
the value of its total assets in domestic and foreign high and medium-grade
fixed income securities of all types, including obligations of corporate and
governmental issuers and mortgage-backed and asset-backed securities. Corporate
obligations include bonds, notes and debentures. Governmental obligations
include securities issued by the U.S. Government, its agencies or
instrumentalities, as well as obligations of foreign governments. High and
medium-grade fixed income securities are those rated in one of the four highest
rating categories by a major rating agency, or determined by the Adviser to be
of equivalent quality. If a security is downgraded, the Adviser will re-evaluate
the holding to determine whether it is in the best interest of investors to
sell. In buying and selling securities for the Fund, the Adviser considers a
number of factors, including yield to maturity, maturity, quality and the
outlook for particular issuers and market sectors. The Fund generally maintains
an average maturity of between three and ten years.


PRINCIPAL RISKS OF INVESTING

The prices of the Fund's fixed income securities respond to economic
developments, particularly interest rate changes, as well as to perceptions
about the creditworthiness of individual issuers, including governments.
Generally, the Fund's fixed income securities will decrease in value if interest
rates rise and vice versa, and the volatility of lower rated securities is even
greater than that of higher rated securities. Also, longer-term securities are
generally more volatile, so the average maturity or duration of these securities
affects risk.

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

The mortgages underlying mortgage-backed securities may be paid off early, which
makes it difficult to determine their actual maturity and therefore calculate
how they will respond to changes in interest rates. The Fund may have to
reinvest prepaid amounts at lower interest rates. This risk of prepayment is an
additional risk of mortgage-backed securities.

Debt extension risk is the risk that an issuer will exercise its right to pay
principal on an obligation held by the Fund (such as an asset-backed security)
later than expected. This may happen during a period of rising interest rates.
Under these circumstances, the value of the obligation will decrease and the
Fund will suffer from the inability to invest in higher yielding securities.

Although the Fund's U.S. Government securities are considered to be among the
safest investments, they are not guaranteed against price movements due to
changing interest rates. Obligations issued by some U.S. Government agencies and
instrumentalities are backed by the U.S. Treasury, while others are backed
solely by the ability of the agency to borrow from the U.S. Treasury or by the
agency's own resources.

Investing in foreign countries poses additional risks since political and
economic events unique to a country or region will affect those markets and
their issuers. These events will not necessarily affect the U.S. economy or
similar issuers located in the United States. In addition, investments in
foreign countries are generally denominated in a foreign currency. As a result,
changes in the value of those currencies compared to the U.S. dollar may affect
(positively or negatively) the value of a Fund's investments. These currency
movements may happen separately from and in response to events that do not
otherwise affect the value of the security

in the issuer's home country. These various risks will be even greater for
investments in emerging market countries since political turmoil and rapid
changes in economic conditions are more likely to occur in these countries.

The Fund is also subject to the risk that its market segment, investment grade
fixed income securities, may underperform other fixed income market segments or
the fixed income market as a whole. For additional information about risks, see

investing in mortgage-backed securities


PRINCIPAL INVESTMENT STRATEGIES

The Armada GNMA Fund's investment objective is to provide current income as well
as preservation of capital by investing primarily in mortgage-backed securities
guaranteed by GMNA. The investment objective may be changed without a
shareholder vote. The Fund normally invests at least 80% of the value of its
total assets in mortgage-backed securities guaranteed by GNMA, which is an
agency of the U.S. Government established to supervise and finance certain types
of mortgages. In addition to mortgage-backed securities, the Fund invests in
other types of investment grade fixed income securities such as U.S. Treasury
obligations, U.S. Government agencies, asset-backed securities and commercial
paper.

In buying and selling securities for the Fund, the Adviser assesses current and
projected market conditions by considering a number of factors, including yield
to maturity, maturity, quality and the outlook for particular issuers and market
sectors.

The Fund's dollar-weighted average portfolio maturity will be between three and
ten years. Investment grade fixed income securities are those rated in one of
the four highest rating categories by a major rating agency, or determined by
the Adviser to be of equivalent quality.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.


PRINCIPAL RISKS OF INVESTING

The prices of the Fund's fixed income securities respond to economic
developments, particularly interest rate changes, as well as to perceptions
about the creditworthiness of individual issuers, including governments.
Generally, the Fund's fixed income securities will decrease in value if interest
rates rise and vice versa. Also, longer-term securities are generally more
volatile, so the average maturity or duration of these securities affects risk.

Mortgage-backed securities are fixed income securities representing an interest
in a pool of underlying mortgage loans. They are sensitive to changes in
interest rates, but may respond to these changes differently from other fixed
income securities due to the possibility of prepayment of the underlying
mortgage loans. As a result, it may not be possible to determine in advance the
actual maturity date or average life of a mortgage-backed security. Rising
interest rates tend to discourage refinancings, with the result that the average
life and volatility of the security will increase, exacerbating its decrease in
market price. When interest rates fall, however, mortgage-backed securities may
not gain as much in market value because of the expectation of additional
mortgage prepayments that must be reinvested at lower interest rates. Prepayment
risk may make it difficult to calculate the average maturity of the fund of
mortgage-backed securities and, therefore, to assess the volatility risk of the
Fund.


Debt extension risk is the risk that an issuer will exercise its right to pay
principal on an obligation held by the Fund (such as an asset-backed security)
later than expected. This may happen during a period of rising interest rates.
Under these circumstances, the value of the obligation will decrease and the
Fund will suffer from the inability to invest in higher yielding securities.

The Fund is also subject to the risk that its market segment, mortgage-backed
securities, may underperform other fixed income market segments or the fixed
income market as a whole.

FUND SUMMARY

INVESTMENT GOAL
Current income exempt from federal income and, to the extent possible, Ohio
personal income taxes, consistent with conservation of capital

INVESTMENT FOCUS
Ohio municipal securities

SHARE PRICE VOLATILITY
(RELATIVE TO MUTUAL FUNDS GENERALLY)
Medium

PRINCIPAL INVESTMENT STRATEGY
Investing in municipal obligations that pay interest that is exempt from Federal
income and Ohio personal income taxes

INVESTOR PROFILE Investors seeking total return and who are willing to accept
some risks of price volatility

PRINCIPAL INVESTMENT STRATEGIES

The Armada Ohio Tax Exempt Bond Fund's investment objective is to provide
current income exempt from federal income tax and, to the extent possible, from
Ohio personal income tax, as is consistent with the conservation of capital. The
investment objective may be changed without a shareholder vote. The Fund
normally invests at least 80% of its total assets in debt securities issued by
the State of Ohio, its political subdivisions and their agencies and
instrumentalities that generate income exempt from federal income and Ohio
personal income taxes (Ohio municipal securities). However, some Fund dividends
will be taxable, such as dividends that are derived from occasional taxable
investments and distributions of short and long-term capital gains. Also, Fund
dividends will generally be subject to state and local income taxes for any
shareholders who are not Ohio residents. The Fund may invest up to 20% of its
total assets in private activity bonds which may be treated as a specific tax
preference item under the federal alternative minimum tax. In selecting
securities for the Fund to buy and sell, the Adviser considers each security's
yield and total return potential relative to other available municipal
securities.

The Fund primarily invests in investment grade securities, which are those rated
in one of the four highest rating categories by a major rating agency, or deter-
mined by the Adviser to be of equivalent quality. If a security is downgraded,
the Adviser will re-evaluate whether continuing to hold the security is in the
best interest of its shareholders. The Fund ordinarily will maintain an average
weighted portfolio maturity of between three and ten years.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and capital gains tax liabilities,
and will lower Fund performance.


PRINCIPAL RISKS OF INVESTING

The prices of the Fund's fixed income securities respond to economic
developments, particularly interest rate changes, as well as to perceptions
about the creditworthiness of individual issuers, including governments.
Generally, the Fund's fixed income securities will decrease in value if interest
rates rise and vice versa. Also, longer-term securities are generally more
volatile, so the average maturity or duration of these securities affects risk.

The Fund is also subject to the risk that its market segment, tax exempt
municipal securities, may underperform other fixed income market segments or the
fixed income market as a whole.

An investment in the Fund is subject to interest risk, which is the possibility
that the Fund's yield will decline due to falling interest rates.

There may be economic or political changes that impact the ability of municipal
issuers to repay principal and to make interest payments on municipal
securities. Changes in the financial condition or credit rating of municipal
issuers also may adversely affect the value of the Fund's securities.

The Fund's focus of investing in securities of issuers located in Ohio subjects
the Fund to economic and government policies of that state.

The Fund is non-diversified, which means that it may invest in the securities of
relatively few issuers. As a result, the Fund may be more susceptible than a
diversified fund to a single adverse economic or political and regulatory
occurrences affecting one or more of these issuers, and may experience increased
volatility due to its investments in those securities. For additional
information about risks, see "More Information About Risk."

PRINCIPAL INVESTMENT STRATEGIES

The Armada Pennsylvania Municipal Bond Fund's investment objective is to provide
current income exempt from regular federal income tax and, to the extent
possible, from Pennsylvania personal income tax, as is consistent with
conservation of capital. The investment objective may be changed without a
shareholder vote. The Fund normally invests at least 80% of its net assets in
debt securities issued by the Commonwealth of Pennsylvania, its political
subdivisions and their agencies and instrumentalities that generate income
exempt from federal income and Pennsylvania personal income taxes (Pennsylvania
municipal securities). However, some Fund dividends will be taxable, such as
dividends that are derived from occasional taxable investments and distributions
of short and long-term capital gains. Also, Fund dividends will generally be
subject to state and local income taxes for any shareholders who are not
Pennsylvania residents. The Fund may invest up to 100% of its total assets in
private activity bonds which may be treated as a specific tax preference item
under the federal alternative minimum tax. In selecting securities for the Fund
to buy and sell, the Adviser considers each security's yield and total return
potential relative to other available municipal securities.

The Fund invests primarily in investment grade securities, which are those rated

operated using materially equivalent investment objectives, policies, guidelines
and restrictions as the Fund. In connection with the National Tax Exempt Bond
Fund's commencement of operations, on April 19, 1998, the common trust fund
transferred its assets to the Fund. At the time of the transfer, the Adviser did
not manage any other collective investment or common trust funds using
materially equivalent investment objectives, policies, guidelines and
restrictions to those of the National Tax Exempt Bond Fund.

The common trust fund was not open to the public generally, nor registered under
the Investment Company Act of 1940 (the "1940 Act") or subject to certain
restrictions that are imposed by the 1940 Act and the Internal Revenue Code. If
the common trust fund had been registered under the 1940 Act, performance may
have been adversely affected. Performance quotations of the common trust fund
represent past performance of the Adviser managed common trust fund, which are
separate and distinct form the National Tax Exempt Bond Fund; do not represent
past performance of the Fund; and should not be considered as representative of
future results of the Fund.

FUND SUMMARY

INVESTMENT GOAL
Current income exempt from regular federal income tax and Ohio personal income
tax consistent with stability of principal

INVESTMENT FOCUS
Ohio municipal money market instruments

SHARE PRICE VOLATILITY
(RELATIVE TO MUTUAL FUNDS GENERALLY)
Very low

PRINCIPAL INVESTMENT STRATEGY
Investing in a portfolio of high quality short-term debt securities designed to
allow the Fund to maintain a stable net asset value of $1.00 per share

INVESTOR PROFILE
Conservative taxable investors in higher tax brackets seeking current income
exempt from federal and Ohio income taxes


PRINCIPAL INVESTMENT STRATEGIES

The Armada Ohio Municipal Money Market Fund's investment objective is to provide
current income exempt from regular federal income tax and Ohio personal income
taxes, consistent with stability of principal. The investment objective may be
changed without a shareholder vote. The Fund invests exclusively in high quality
money market instruments issued by or on behalf of the State of Ohio, political
subdivisions thereof or agencies or instrumentalities of Ohio or its political
subdivisions, the income from which is exempt from regular federal income tax
and Ohio personal income tax (Ohio money market instruments). However, some Fund
dividends may be taxable if the Fund, as it is permitted to do, invests some of
its assets in taxable instruments. Also, Fund dividends will generally be
subject to state and local income taxes for any shareholders who are not Ohio
residents. High quality money market instruments are securities that present
minimal credit risks as determined by the Adviser and generally include
securities that are rated at the time of purchase by a major rating agency in
the two highest rating categories for such securities, and certain securities
that are not rated but are of comparable quality as determined by the Adviser.

The Fund may invest 100% of its assets in private activity bonds, the interest
from which is a preference item for the federal alternative minimum tax. Under
normal market conditions, at least 80% of the value of the Fund's total assets
will be invested in Ohio money market instruments. This policy is fundamental
and may not be changed without the affirmative vote of the holders of a majority
of the Fund's outstanding shares.

In managing the Fund, the Adviser assesses current and projected market
conditions, particularly interest rates. Based on this assessment and a separate
credit analysis, the Adviser uses gradual shifts in portfolio maturity to
respond to expected changes and selects securities that it believes offer the
most attractive risk/return trade off.

As a money market fund, the Fund invests only in instruments with remaining
maturities of 397 days or less that the Adviser believes present minimal credit
risk. The Fund maintains an average weighted maturity of 90 days or less.

PRINCIPAL RISKS OF INVESTING

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

The Fund is also subject to the risk that its market segment, Ohio municipal
money market securities, may underperform other fixed income market segments or
the fixed income market as a whole.

There may be economic or political changes that impact the ability of municipal
issuers to repay principal and to make interest payments on municipal
securities. Changes in the financial condition or credit rating of municipal
issuers also may adversely affect the value of the Fund's securities.

The Fund's focus of investments in securities of issuers located in Ohio
subjects the Fund to economic and government policies of that state. For
additional information about risks, see "More Information About Risk."

PRINCIPAL INVESTMENT STRATEGIES

The Armada Pennsylvania Tax Exempt Money Market Fund's investment objective is
to provide current income exempt from regular federal income tax and
Pennsylvania personal income tax, consistent with stability of principal. The
investment objective may be changed without a shareholder vote. The Fund invests
exclusively in high quality money market instruments issued by or on behalf of
the Commonwealth of Pennsylvania and its political subdivisions and financing
authorities, and obligations of the United States, including territories and
possessions of the United States, the income from which is exempt from regular
federal income tax and Pennsylvania income taxes (Pennsylvania municipal money
market instruments). However, some Fund dividends may be taxable if the Fund, as
it is permitted to do, invests some of its assets in taxable instruments. Also,
Fund dividends will generally be subject to state and local income taxes for any
shareholders who are not Pennsylvania residents. High quality money market
instruments are securities that present minimal credit risks as determined by
the Adviser and generally include securities that are rated at the time of
purchase by a major rating agency in the two highest rating categories for such
securities, and certain securities that are not rated but are of comparable
quality as determined by the Adviser. As a matter of fundamental policy, the
Fund invests its assets so that at least 80% of its annual interest income is
not only exempt from regular federal income tax and Pennsylvania personal income
tax, but it is not considered a preference item for purposes of the federal
alternative minimum tax.

In managing the Fund, the Adviser assesses current and projected market
conditions, particularly interest rates. Based on this assessment and a separate
credit analysis, the Adviser uses gradual shifts in portfolio maturity to
respond to expected changes and selects securities that it believes offer the

PRINCIPAL INVESTMENT STRATEGIES

The Armada Money Market Fund's investment objective is to provide as high a
level of current income as is consistent with liquidity and stability of
principal. The investment objective may be changed without a shareholder vote.
The Fund invests in a variety of high quality money market securities, including
certificates of deposit and other obligations issued by domestic and foreign
banks, as well as commercial paper. Foreign government obligations are U.S.
dollar-denominated obligations (limited to commercial paper and other notes)
issued or guaranteed by a foreign government or other entity located or
organized in a foreign country that maintains a short-term foreign currency
rating in the highest short-term ratings category by the requisite number of
Nationally Recognized Statistical Rating Organizations (NRSROs). The Adviser
also invests in securities issued or guaranteed by the U.S. Government or its
agencies (government obligations) and repurchase agreements collateralized by
government obligations and issued by financial institutions such as banks and
broker-dealers. High quality money market instruments are securities that
present minimal credit risks as determined by the Adviser and generally include
securities that are rated at the time of purchase by a major rating agency in
the highest two rating categories for such securities, and certain securities
that are not rated but are of comparable quality as determined by the Adviser.

In selecting investments for the Fund, the Adviser actively buys throughout
the money market curve, laddering maturities to meet or exceed shareholder
liquidity needs while seeking the highest possible yield consistent with the
Fund's risk profile.

As a money market fund, the Fund invests only in money market instruments with
remaining maturities of 397 days or less that the Adviser believes present
minimum credit risk. The Fund maintains an average weighted maturity of 90 days
or less.


PRINCIPAL RISKS OF INVESTING

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

The Fund is also subject to the risk that its market segment, money market
securities, may underperform other fixed income market segments or the fixed
income market as a whole. For additional information about risks, see "More
Information About Risk."

FUND SUMMARY

INVESTMENT GOAL
High current income consistent with stability of principal while maintaining
liquidity

INVESTMENT FOCUS
Money market instruments issued or guaranteed by the U.S. Government, its
agencies and instrumentalities and repurchase agreements

SHARE PRICE VOLATILITY
(RELATIVE TO MUTUAL FUNDS GENERALLY)
Very low

PRINCIPAL INVESTMENT STRATEGY
Investing in a portfolio of high quality short-term debt securities issued by
the U.S. Government, its agencies and instrumentalities and repurchase
agreements related to such securities designed to allow the Fund to maintain a
stable net asset value of $1.00 per share

INVESTOR PROFILE
Conservative investors seeking current income through a liquid investment

PRINCIPAL INVESTMENT STRATEGIES

The Armada Government Money Market Fund's investment objective is to provide as
high a level of current income as is consistent with liquidity and stability of
principal. The investment objective may be changed without a shareholder vote.
The Fund invests exclusively in obligations issued or guaranteed as to the
payment of principal and interest by the U.S. Government, its agencies and
instrumentalities and repurchase agreements. U.S. Government securities include
direct obligations of the U.S. Treasury, and obligations of certain agencies
such as GNMA and FNMA.

In managing the Fund, the Adviser actively buys throughout the money market
curve, laddering maturities to meet or exceed shareholder liquidity needs while
seeking the highest possible yield consistent with the Fund's risk profile.

As a money market fund, the Fund invests only in money market instruments with
remaining maturities of 397 days or less and maintains an average weighted
maturity of 90 days or less.


PRINCIPAL RISKS OF INVESTING

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

Although the Fund's U.S. Government securities are considered to be among the
safest investments, they are not guaranteed against price movements due to
changing interest rates. Obligations issued by some U.S. Government agencies and
instrumentalities are backed by the U.S. Treasury, while others are backed
solely by the ability of the agency to borrow from the U.S. Treasury or by the
agency's own resources.

The Fund is also subject to the risk that its market segment, money market
instruments issued or guaranteed by the U.S. Government, may underperform other
fixed income market segments or the fixed income market as a whole.

                           ARMADA MID CAP GROWTH FUND

FUND SUMMARY

INVESTMENT GOAL
Capital appreciation

INVESTMENT FOCUS
Mid-cap equity securities

Share Price Volatility
(relative to mutual funds generally)
High

PRINCIPAL INVESTMENT STRATEGY
Investing in growth-oriented equity securities of medium-sized issuers

INVESTOR PROFILE

Investors seeking capital growth, and who are willing to accept the risks of
investing in equity securities


PRINCIPAL INVESTMENT STRATEGIES

The Armada Mid Cap Growth Fund's investment objective is to provide capital
appreciation by investing in a diversified portfolio of publicly traded mid cap
equity securities. The investment objective may be changed without a shareholder
vote. The Fund will normally invest at least 80% of its total assets in the
common stock of companies with mid stock market capitalizations. The Fund may
invest up to 20% of its total assets at the time of purchase in foreign equity
securities. In selecting investments for the Fund to buy and sell, the Adviser
invests in companies that have typically exhibited consistent, above-average
growth in revenues and earnings, strong management, sound and improving
financial fundamentals and presently exhibit the potential for growth.

The Fund considers a "mid-capitalization (mid cap)" company to be one that has a
comparable market capitalization within the range as the companies in the
Russell Mid Cap Growth Index. The Russell MidCap Growth Index is an unmanaged
index which reflects a medium-sized universe of growth-oriented securities.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.


PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity
securities may fluctuate from day-to-day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by such companies may decline in
response. These factors contribute to price volatility, which is the principal
risk of investing in the Fund.

Investing in foreign countries poses additional risks since political and
economic events unique to a country or region will affect those markets and
their issuers. These events will not necessarily affect the U.S. economy or
similar issuers located in the United States. In addition, investments in
foreign countries are generally denominated in a foreign currency. As a result,
changes in the value of those currencies compared to the U.S. dollar may affect
(positively or negatively) the value of a Fund's investments. These currency
movements may happen separately from and in response to events that do not
otherwise affect the value of the security in the issuer's home country.

The Fund is also subject to the risk that its market segment, mid cap equity
securities, may underperform other equity market segments or the equity market
as a whole. For additional information about risks, see "More Information About
Risk."

INVESTOR PROFILE

Investors seeking growth of capital, and who are willing to accept the risks of

PRINCIPAL INVESTMENT STRATEGIES

The Armada Large Cap Ultra Fund's investment objective is to provide capital
appreciation by investing in a diversified portfolio of publicly traded larger
cap equity securities. The investment objective may be changed without a
shareholder vote. The Fund will normally invest at least 80% of its total assets
in the common stock of companies with large market capitalizations.

The Adviser takes a long-term approach to managing the Fund and typically
invests in companies that have exhibited consistent, above-average growth in
revenues and earnings, strong management, and sound and improving financial
fundamentals.

The Fund considers a large capitalization or "large cap" company to be one that
has a comparable market capitalization as the companies in the S&P 500/Barra
Growth Index. The S&P 500/Barra Growth Index is an unmanaged index comprised of
common stocks which are capitalization-weighted and have higher price-to-book
ratios.


PRINCIPAL RISKS OF INVESTING

Since it purchases equity securities, the Fund is subject to the risk that stock
prices will fall over short or extended periods of time. Historically, the
equity markets have moved in cycles, and the value of the Fund's equity
securities may fluctuate from day-to-day. Individual companies may report poor
results or be negatively affected by industry and/or economic trends and
developments. The prices of securities issued by such companies may decline in
response. These factors contribute to price volatility, which is the principal
risk of investing in the Fund.

The Fund is also subject to the risk that its market segment, large cap equity
securities, may underperform other equity market segments or the equity market

FUND SUMMARY

Current income as well as preservation of capital

INVESTMENT FOCUS
Mortgage backed securities

SHARE PRICE VOLATILITY
(RELATIVE TO MUTUAL FUNDS GENERALLY)
Low

PRINCIPAL INVESTMENT STRATEGY
Investing in mortgage-related securities issued or guaranteed by
the U.S. Government

INVESTOR PROFILE
Investors seeking current income, and who are willing to accept the risks of
investing in fixed income securities

PRINCIPAL INVESTMENT STRATEGIES

The Armada U.S. Government Income Fund's investment objective is to provide
current income as well as preservation of capital by investing primarily in U.S.
Government securities. The investment objective may be changed without a
shareholder vote. The Fund normally invests at least 80% of its total assets in
obligations issued or guaranteed by the U.S. Government or its agencies or
instrumentalities. The types of U.S. Government securities include
mortgage-related securities, and Treasury bills, notes and bonds. The Fund may
invest up to 20% of the value of its total assets in mortgage-related debt
securities and preferred stock of non-governmental issuers and the same
proportion of its total assets in non-governmental asset backed securities. In
buying and selling securities for the Fund, the Adviser considers a number of
factors, including yield to maturity, maturity, quality and the outlook for
particular issuers and market sectors. The Fund generally maintains a
dollar-weighted average maturity of between three and ten years.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.


PRINCIPAL RISKS OF INVESTING


The prices of the Fund's fixed income securities respond to economic
developments, particularly interest rate changes, as well as to perceptions
about the creditworthiness of individual issuers, including governments.
Generally, the Fund's fixed income securities will decrease in value if interest
rates rise and vice versa. Also, longer-term securities are generally more
volatile, so the average maturity or duration of these securities affects risk.

The Fund is also subject to the risk that its market segment, U.S. Government
securities, may underperform other fixed income market segments or the fixed
income market as a whole.

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

The mortgages underlying mortgage-backed securities may be paid off early, which
makes it difficult to determine their actual maturity and therefore calculate
how they will respond to changes in interest rates. The Fund may have to
reinvest prepaid amounts at lower interest rates. This risk of prepayment is an
additional risk of mortgage-backed securities.

Debt extension risk is the risk that an issuer will exercise its right to pay
principal on an obligation held by the Fund (such as an asset-backed security)
later than expected. This may happen during a period of rising interest rates.
Under these circumstances, the value of the obligation will decrease and the
Fund will suffer from the inability to invest in higher yielding securities.

Although the Fund's U.S. Government securities are considered to be among the
safest investments, they are not guaranteed against price movements due to
changing interest rates. Obligations issued by some U.S. Government agencies and
instrumentalities are backed by the U.S. Treasury, while others are backed
solely by the ability of the agency to borrow from the U.S. Treasury or by the
agency's own resources. For additional information about risks, see "More
Information About Risk."

FUND SUMMARY

Current income exempt from federal income tax and, to the extent possible, from
Michigan personal income tax, as is consistent with conservation of capital

INVESTMENT FOCUS
Michigan tax exempt securities

SHARE PRICE VOLATILITY
(RELATIVE TO MUTUAL FUNDS GENERALLY)
Medium

PRINCIPAL INVESTMENT STRATEGY
Investing in municipal obligations that pay interest that is exempt from federal
and Michigan state income taxes

INVESTOR PROFILE
Investors seeking tax exempt current income, and who are willing to accept
moderate share price volatility

PRINCIPAL INVESTMENT STRATEGIES

The Armada Michigan Municipal Bond Fund's investment objective is to provide
current income exempt from federal income tax and, to the extent possible, from
Michigan personal income tax, as is consistent with conservation of capital.
Such income may be subject to the federal alternative minimum tax when received
by certain shareholders. The investment objective may be changed without a
shareholder vote. The Fund invests primarily in debt securities issued by or on
behalf of the State of Michigan, its political subdivisions and its agencies and
instrumentalities that generate income exempt from federal and Michigan state
income, but may be treated as a preference item for individuals for purposes of
the federal alternative minimum tax (Michigan municipal securities). The Fund
also invests in municipal securities issued by or on behalf of territories and
possessions of the United States, the District of Columbia and their political
subdivisions, agencies, instrumentalities and authorities. In selecting
securities for the Fund to buy and sell, the Adviser considers each security's
yield and total return potential relative to other available municipal
securities. The Fund will normally invest at least 80% of the value of its total
assets in Michigan municipal securities. However, some Fund dividends will be
taxable, such as dividends that are derived from occasional taxable investments
and distributions of short and long-term capital gains. Also, Fund dividends
will generally be subject to state and local income taxes for any shareholders
who are not Michigan residents. The Fund may invest up to 100% of its total
assets in private activity bonds which may be treated as a specific tax
preference item under the federal alternative minimum tax.

The Fund invests in investment grade securities, which are those rated in one of
the four highest rating categories by a major rating agency, or determined by
the Adviser to be of equivalent quality. If a security is downgraded, the
Adviser will re-evaluate whether continuing to hold the security is in the best
interest of its shareholders. The Fund ordinarily will maintain a
dollar-weighted average portfolio maturity of between three and ten years.

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs and additional capital gains tax
liabilities, and will lower Fund performance.


PRINCIPAL RISKS OF INVESTING

The prices of the Fund's fixed income securities respond to economic
developments, particularly interest rate changes, as well as to perceptions
about the creditworthiness of individual issuers, including governments.
Generally, the Fund's fixed income securities will decrease in value if interest
rates rise and vice versa. Also, longer-term securities are generally more
volatile, so the average maturity or duration of these securities affects risk.

The Fund is also subject to the risk that its market segment, tax free municipal
securities, may underperform other fixed income market segments or the fixed
income market as a whole.

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

There may be economic or political changes that impact the ability of municipal
issuers to repay principal and to make interest payments on municipal
securities. Changes in the financial condition or credit rating of municipal
issuers also may adversely affect the value of the Fund's securities.

               ARMADA MICHIGAN MUNICIPAL BOND FUND (CONTINUED)

PRINCIPAL RISKS OF INVESTING (continued)

The Fund's focus of investments in securities of issuers located in Michigan
subjects the Fund to economic and government policies of that state.

The Fund is non-diversified, which means that it may invest in the securities of
relatively few issuers. As a result, the Fund may be more susceptible than a
diversified fund to a single adverse economic or political and regulatory
occurrences affecting one or more of these issuers, and may experience increased
volatility due to its investments in those securities. For additional
information about risks, see "More Information About Risk."

PRINCIPAL INVESTMENT STRATEGY
Investing in a portfolio of high quality short-term obligations of the U.S.
Treasury designed to allow the Fund to maintain a stable net asset value of

INVESTOR PROFILE
Investors seeking current income through a liquid and stable investment


PRINCIPAL INVESTMENT STRATEGIES

The Armada Treasury Plus Money Market Fund's investment objective is to provide
current income with liquidity and stability of principal. The investment
objective may be changed without a shareholder vote. The Fund invests
exclusively in obligations issued or guaranteed by the U.S. Treasury and
repurchase agreements related to such securities.

In managing the Fund, the Adviser assesses current and projected market
conditions. Based on this assessment, the Adviser uses gradual shifts in
portfolio maturity to respond to expected changes and selects securities that it
believes offer the most attractive trade off between risk and return.

As a money market fund, the Fund invests only in money market instruments
with remaining maturities of 397 days or less and maintains an average weighted
maturity of 90 days or less.

PRINCIPAL RISKS OF INVESTING

The prices of the Fund's fixed income securities respond to economic develop-
ments, particularly interest rate changes.  Generally, the Fund's fixed income
securities will decrease in value if interest rates rise and vice versa.

An investment in the Fund is subject to interest rate risk, which is the
possibility that the Fund's yield will decline due to falling interest rates.

Although the Fund's U.S. Treasury securities are considered to be among the
safest investments, they are not guaranteed against price movements due to
changing interest rates.  Obligations issued by the U.S. Treasury are backed by
the U.S. Treasury.

The Fund is also subject to the risk that its market segment, U.S. Treasury
securities, may underperform other fixed income market segments or the fixed
income market as a whole.  For additional information about risks, see "More
Information About Risk."

60 PROSPECTUS

<PAGE>   183


EQUITY RISK -- Equity securities include public and privately issued equity
securities, common and preferred stocks, warrants, rights to subscribe to common
stock and convertible securities, as well as instruments that attempt to track
the price movement of equity indices. Investments in equity securities and
equity derivatives in general are subject to market risks that may cause their
prices to fluctuate over time. The value of securities convertible into equity
securities, such as warrants or convertible debt, is also affected by prevailing
interest rates, the credit quality of the issuer and any call provision.
Fluctuations in the value of equity securities in which a mutual fund invests
will cause a fund's net asset value to fluctuate. An investment in a portfolio
of equity securities may be more suitable for long-term investors who can bear
the risk of these share price fluctuations.

     CONVERTIBLE SECURITIES -- Convertible securities have characteristics of
     both fixed income and equity securities. The value of the convertible
     security tends to move with the market value of the underlying stock, but
     may also be affected by interest rates, credit quality of the issuer and
     any call provisions.

FIXED INCOME RISK -- The market value of fixed income investments change in
response to interest rate changes and other factors. During periods of falling
interest rates, the values of outstanding fixed income securities generally
rise. Moreover, while securities with longer maturities tend to produce higher
yields, the prices of longer maturity securities are also subject to greater
market fluctuations as a result of changes in interest rates. In addition to
these fundamental risks, different types of fixed income securities may be
subject to the following additional risks:

     CALL RISK --During periods of falling interest rates, certain debt
     obligations with high interest rates may be prepaid (or "called") by the
     issuer prior to maturity. This may cause a Fund's average weighted maturity
     to fluctuate, and may require a Fund to invest the resulting proceeds at
     lower interest rates.

     CREDIT RISK --The possibility that an issuer will be unable to make timely
     payments of either principal or interest.

     EVENT RISK --Securities may suffer declines in credit quality and market
     value due to issuer restructurings or other factors. This risk should be
     reduced because of the diversification provided by the Fund's multiple
     holdings.

HIGH-YIELD, LOWER RATED SECURITIES(or "junk bonds") are subject to additional
risks associated with investing in high-yield securities, including:

- -    High-yield, lower rated securities involve greater risk of default or price
     declines than investments in investment grade securities (e.g., securities
     rated BBB or higher by S&Por Baa or higher by Moody's) due to changes in
     the issuer's creditworthiness.

- -    The market for high-yield, lower rated securities may be thinner and less
     active, causing market price volatility and limited liquidity in the
     secondary market. This may limit the ability of a Fund to sell these
     securities at their fair market values either to meet redemption requests,
     or in response to changes in the economy or the financial markets.

- -    Market prices for high-yield, lower rated securities may also be affected
     by investors' perception of the issuer's credit quality and the outlook for
     economic growth. Thus, prices for high-yield, lower rated securities may
     move independently of interest rates and the overall bond market.

- -    The market for high-yield, lower rated securities may be adversely affected
     by legislative and regulatory developments.

MUNICIPAL ISSUER RISK --There may be economic or political changes that impact
the ability of municipal issuers to repay principal and to make interest
payments on municipal securities. Changes to the financial condition or credit
rating of municipal issuers may also adversely affect the value of the Fund's
municipal securities. Constitutional or legislative limits on borrowing by
municipal issuers may result in reduced supplies of municipal securities.
Moreover, certain municipal securities are backed only by a municipal issuer's
ability to levy and collect taxes.

In addition, the Fund's concentration of investments in issuers located in a
single state makes the Fund more susceptible to adverse political or economic
developments affecting that state. The Fund also may be riskier than mutual
funds that buy securities of issuers in numerous states.


                                                                   61 PROSPECTUS

<PAGE>   184


     MORTGAGE-BACKED SECURITIES -- Mortgage-backed securities are fixed income
     securities representing an interest in a pool of underlying mortgage loans.
     They are sensitive to changes in interest rates, but may respond to these
     changes differently from other fixed income securities due to the
     possibility of prepayment of the underlying mortgage loans. As a result, it
     may not be possible to determine in advance the actual maturity date or
     average life of a mortgage-backed security. Rising interest rates tend to
     discourage refinancings, with the result that the average life and
     volatility of the security will increase exacerbating its decrease in
     market price. When interest rates fall, however, mortgage-backed securities
     may not gain as much in market value because of the expectation of
     additional mortgage prepayments that must be reinvested at lower interest
     rates. Prepayment risk may make it difficult to calculate the average
     maturity of a portfolio of mortgage-backed securities and, therefore, to
     assess the volatility risk of that portfolio.

FOREIGN SECURITY RISKS --Investments in securities of foreign companies or
governments can be more volatile than investments in U.S. companies or
governments. Diplomatic, political, or economic developments, including
nationalization or appropriation, could affect investments in foreign countries.
Foreign securities markets generally have less trading volume and less liquidity
than U.S. markets. In addition, the value of securities denominated in foreign
currencies, and of dividends from such securities, can change significantly when
foreign currencies strengthen or weaken relative to the U.S. dollar. Foreign
companies or governments generally are not subject to uniform accounting,
auditing, and financial reporting standards comparable to those applicable to
domestic U.S. companies or governments. Transaction costs are generally higher
than those in the U.S. and expenses for custodial arrangements of foreign
securities may be somewhat greater than typical expenses for custodial
arrangements of similar U.S. securities. Investment in sovereign debt
obligations by certain Funds involves risks not present in debt obligations of
corporate issuers. The issuer of the debt or the governmental authorities that
control the repayment of the debt may be unable or unwilling to repay principal
or interest when due in accordance with the terms of such debt, and a Fund may
have limited recourse to compel payment in the event of a default. Periods of
economic uncertainty may result in volatility of market prices of sovereign
debt, and in turn a Fund's NAV, to a greater extent than the volatility inherent
in debt obligations of U.S. issuers. Some foreign governments levy withholding
taxes against dividend and interest income. Although in some countries a portion
of these taxes are recoverable, the non-recovered portion will reduce the income
received from the securities comprising the portfolio.

In addition to these risks, certain foreign securities may be subject to the
following additional risks factors:

     CURRENCY RISK --Investments in foreign securities denominated in foreign
     currencies involve additional risks, including:

     -   The value of a Fund's assets measured in U.S. dollars may be affected
         by changes in currency rates and in exchange control regulations.

     -   A Fund may incur substantial costs in connection with conversions
         between various currencies.

     -   A Fund may be unable to hedge against possible variations in foreign
         exchange rates or to hedge a specific security transaction or portfolio
         position.

     -   Only a limited market currently exists for hedging transactions
         relating to currencies in certain emerging markets.

HEDGING RISK --Hedging is a strategy designed to offset investment risks.
Hedging activities include, among other things, the use of forwards, options and
futures. There are risks associated with hedging activities, including:

- -    The success of a hedging strategy may depend on an ability to predict
     movements in the prices of individual securities, fluctuations in markets,
     and movements in interest and currency exchange rates.

- -    There may be an imperfect or no correlation between the changes in market
     value of the securities held by the Fund or the currencies in which those
     securities are denominated and the prices of forward contracts, futures and
     options on futures.

- -    There may not be a liquid secondary market for a futures contract or
     option.

- -    Trading restrictions or limitations may be imposed by an exchange, and
     government regulations may restrict trading in currencies, futures
     contracts and options.

LEVERAGING RISK --Leveraging activities include, among other things, borrowing
and the use of short sales, options and futures. There are risks associated with
leveraging activities, including:

- -    A fund experiencing losses over certain ranges in the market that exceed
     losses experienced by a non-leveraged Fund.

- -    There may be an imperfect or no correlation between the changes in market
     value of the securities held by a fund and the prices of futures and
     options on futures.

- -    Although the funds will only purchase exchange-traded futures and options,
     due to market conditions there may not be a liquid secondary market for a
     futures contract or option. As a result, the funds may be unable to close
     out their futures or options contracts at a time which is advantageous.

- -    Trading restrictions or limitations may be imposed by an exchange, and
     government regulations may restrict trading in futures contracts and
     options.

In addition, the following leveraged instruments are subject to certain specific
risks:

     DERIVATIVES RISK --The Funds use derivatives to attempt to achieve their
     investment objectives, while at the same time maintaining liquidity. To
     collateralize (or cover) these derivatives transactions, the Funds hold
     cash or U.S. government securities.

     FUTURES -- Futures contracts and options on futures contracts provide for
     the future sale by one party and purchase by another party of a specified
     amount of a specific security at a specified future time and at a specified
     price. An option on a futures contract gives the purchaser the right, in
     exchange for a premium, to assume a position in a futures contract at a
     specified exercise price during the term of the option. Index futures are
     futures contracts for various indices that are traded on registered
     securities exchanges.

     The Funds may use futures contracts and related options for bona fide
     hedging purposes to offset changes in the value of securities held or
     expected to be acquired. They may also be used to gain exposure to a
     particular market or instrument, to create a synthetic money market
     position, and for certain other tax-related purposes. The Funds will only
     enter into futures contracts traded on a national futures exchange or board
     of trade.

     OPTIONS -- The buyer of an option acquires the right to buy (a call option)
     or sell (a put option) a certain quantity of a security (the underlying
     security) or instrument at a certain price up to a specified point in time.
     The seller or writer of an option is obligated to sell (a call option) or
     buy (a put option) the underlying security. When writing (selling) call
     options on securities, the Funds may cover its position by owning the
     underlying security on which the option is written or by owning a call
     option on the underlying security. Alternatively, the Funds may cover its
     position by maintaining in a segregated account cash or liquid securities
     equal in value to the exercise price of the call option written by the
     Funds.

     Because option premiums paid or received by the Funds are small in relation
     to the market value of the investments underlying the options, buying and
     selling put and call options can be more speculative than investing
     directly in securities.

     SHORT SALES -- Short sales are transactions in which a Fund sells a
     security it does not own. To complete a short sale, a Fund must borrow the
     security to deliver to the buyer. The Fund is then obligated to replace the
     borrowed security by purchasing the security at the market price at the
     time of replacement. This price may be more or less than the price at which
     the security was sold by the Fund.

REAL ESTATE INVESTING -- The Fund's investments in the securities of real estate
investment trusts (REITs) and companies principally engaged in the real estate
industry may subject the Fund to the risks associated with the direct ownership
of real estate. Risks commonly associated with the direct ownership of real
estate include fluctuations in the value of underlying properties and defaults
by borrowers or tenants. In addition to these risks, REITs are dependent on
specialized management skills and some REITs may have investments in relatively
few properties, or in a small geographic area or a single type of property.
These factors may increase the volatility of the Fund's investments in REITs.

REGIONAL RISK -- To the extent that a Fund's investments are focused in a
specific geographic region, the Fund may be subject to the political and other
developments affecting that region. Regional economies are often closely
interrelated, and political and economic developments affecting one region,
country or state often affect other regions, countries or states, thus
subjecting a Fund to additional risks.

TRACKING ERROR RISK -- Factors such as Fund expenses, imperfect correlation
between the Fund's investments and those of their benchmarks, rounding of share
prices, changes to the benchmark, regulatory policies, and leverage, may affect
their ability to achieve perfect correlation. The magnitude of any tracking
error may be affected by a higher portfolio turnover rate. Because an index is
just a composite of the prices of the securities it represents rather than an
actual portfolio of those securities, an index will have no expenses. As a
result, a Fund, which will have expenses such as taxes, custody, management fees
and other operational costs, and brokerage, may not achieve its investment
objective of accurately correlating to an index.


                                                                   63 PROSPECTUS

<PAGE>   186



YEAR 2000 RISK -- The Funds depend on the smooth functioning of computer systems
in almost every aspect of their business. Like other mutual funds, businesses
and individuals around the world, the Funds could be adversely affected if the
computer systems used by its service providers do not properly process dates on
and after January 1, 2000, and distinguish between the year 2000 and the year
1900. The Funds have asked their service providers whether they expect to have
their computer systems adjusted for the year 2000 transition, and is seeking
assurances from each service provider that they are devoting significant
resources to prevent material adverse consequences to the Funds. While it is
likely that such assurances will be obtained, the Funds and their shareholders
may experience losses if these assurances prove to be incorrect or as a result
of year 2000 computer difficulties experienced by issuers of portfolio
securities or third parties, such as custodians, banks, broker-dealers or others
with which the Funds do business. In addition, to the extent that the operations
of issuers of securities held by a Fund are impaired by the year 2000
transition, or prices of securities held by a Fund decline as a result of real
or perceived problems relating to the year 2000, the value of such Fund's shares
may be materially affected.

Furthermore, many foreign countries are not as prepared as the U.S. for the year
2000 transition. As a result, computer difficulties in foreign markets and with
foreign institutions as a result of the year 2000 may add to the possibility of
losses to the Funds and their shareholders.

EACH FUND'S OTHER INVESTMENTS

In addition to the investments and strategies described in this prospectus, each
Fund also may invest in other securities, use other strategies and engage in
other investment practices. These investments and strategies, as well as those
described in this prospectus, are described in detail in our Statement of
Additional Information. Of course, the Trust cannot guarantee that any Fund will
achieve its investment goal.

The investments and strategies described in this prospectus are those that we
use under normal conditions. During unusual economic, market, political or other
conditions, or for temporary defensive or liquidity purposes, each Fund (except
for the money market funds) may invest up to 100% of its assets in short-term
high quality debt instruments that would not ordinarily be consistent with a
Fund's principal investment strategies. AFund will do so only if the Adviser or
Sub-Adviser believes that the risk of loss outweighs the opportunity for
achieving a Fund's investment objective.

INVESTMENT ADVISER, SUB-ADVISER AND INVESTMENT TEAM

The Investment Adviser makes investment decisions for the Funds and continuously
reviews, supervises and administers each Fund's respective investment program.

The Investment Adviser oversees the Sub-Adviser to ensure compliance with the
Funds' investment policies and guidelines, and monitors the Sub-Adviser's
adherence to its investment style. The Adviser pays the Sub-Adviser out of the
Investment Advisory fees it receives (described below).

The Board of Trustees of the Trust supervises the Adviser and establishes
policies that the Adviser must follow in its management activities.

National City Investment Management Company ("IMC"), with its principal offices
at 1900 East Ninth Street, Cleveland, Ohio 44114, serves as Adviser to the
Funds. On June 30, 1999, IMC had approximately $25.4 billion in assets under
management.

IMC utilizes a team approach for management of the Funds. No one person is
primarily responsible for making investment recommendations to the team. In the
case of the Armada Core Equity and the Armada Total Return Advantage Funds,
National Asset Management Corporation ("NAM") serves as Sub-Adviser and manages
these funds on a day-to-day basis; NAM selects, buys and sells the securities of
these Funds under the supervision of the Adviser and the Board of Trustees.

PURCHASING, SELLING AND EXCHANGING FUND SHARES

This section tells you how to buy, sell (sometimes called "redeem") or exchange
Class I Shares of the Funds.

Class I Shares have no sales charge and no minimum initial investment.

Class I Shares are for financial institutions investing for their own or their
customers' accounts. For information on how to open an account and set up
procedures for placing transactions call 1-800-622-FUND (3863).

HOW TO PURCHASE FUND SHARES

You may buy shares through accounts with brokers and other institutions that are
authorized to place trades in Fund shares for their customers. If you invest
through an authorized institution, you will have to follow its procedures. Your
institution may charge a fee for its services, in addition to the fees charged
by the Trust. You will also generally have to address your correspondence or
questions regarding a Fund to your institution.

GENERAL INFORMATION

You may purchase shares on any day that the New York Stock Exchange is open for
business (a "Business Day").

The Trust may reject any purchase order if it is determined that accepting the
order would not be in the best interests of the Fund or its shareholders.

The price per share (the offering price) will be the net asset value of $1.00
per share (NAV) next determined after a Fund receives your purchase order. The
NAV per share of the Armada Money Market and Government Money Market Funds is
calculated first at 3:00 p.m. (Eastern time), then as of the close of trading of
the New York Stock Exchange. The NAV per share of the Armada Treasury Money
Market, Tax Exempt Money Market, Pennsylvania Tax Exempt Money Market, Ohio
Municipal Money Market and Treasury Plus Money Market Funds are calculated on
each business day first at 1:00 p.m. (Eastern time), then as of the close of
trading of the New York Stock Exchange.

Each bond and equity fund calculates its NAV once each Business Day at the
regularly-scheduled close of normal trading on the New York Stock Exchange
(normally, 4:00 p.m. (Eastern time)). So, for you to receive the current
Business Day's NAV, generally a Fund must receive your purchase order before
4:00 p.m. (Eastern time).

So, for you to be eligible to receive dividends declared on the day you submit
your purchase order, generally a Fund must receive your order before 4:00 p.m.
(Eastern time) and federal funds (readily available funds) before 2:00 p.m.
(Eastern time) the following business day.

Purchase orders for shares of the Armada Money Market and Government Money
Market Funds which are received by the Transfer Agent by 3:00 p.m. (Eastern
time) are processed that day. Purchase orders for shares of the Armada Treasury
Money Market, Tax Exempt Money Market, Pennsylvania Tax Exempt Money Market,
Ohio Municipal Money Market and Treasury Plus Money Market Funds which are
received by the Transfer Agent by 1:00 p.m. (Eastern time) are also processed
that day.

HOW WE CALCULATE NAV

NAV for one Fund share is the value of that share's portion of all of the assets
in the Fund less liabilities and class expenses.

NON-MONEY MARKET FUNDS

In calculating NAV, a non-money market fund generally values its investment
portfolio at market price. In the event that a sale of a particular fixed income
security is not reported for that day, fixed income securities are priced at the
mean between the most recent quoted bid and asked prices. Unlisted securities
and securities traded on a national securities market for which market
quotations are readily available are valued at the mean between the most recent
bid and asked prices. In the event that a sale of a particular equity security
is not reported for that day, shares are priced at the last bid quotation. If
market prices are unavailable or a Fund thinks that they are unreliable, fair
value prices may be determined in good faith using methods approved by the Board
of Trustees.

MONEY MARKET FUNDS

In calculating NAV for the money market funds, we generally value a Fund's
investment portfolio using the amortized cost valuation method, which is
described in detail in our Statement of Additional Information. If this method
is determined to be unreliable during certain market conditions or for other
reasons, a Fund may value its portfolio at market price or fair value prices may
be determined in good faith using methods approved by the Board of Trustees.

Some Funds hold securities that are listed on foreign exchanges. These
securities may trade on weekends or other days when the Funds do not calculate
NAV. As a result, the market value of these Fund's investments may change on
days when you cannot purchase or sell Fund shares.

HOW TO SELL YOUR FUND SHARES

Holders of Class I Shares may sell shares by following procedures established
when they opened their account or accounts. If you have questions, call
1-800-622-FUND (3863).

If you own your shares through an account with a broker or other institution,
contact that broker or institution to sell your shares.

The sale price of each share will be the next NAV determined after the Fund
receives your request.

RECEIVING YOUR MONEY

Normally, we will send your sale proceeds within seven Business Days after we
receive your request in good order. Good order means that your request includes
complete information on your purchase, exchange or redemption and that the Fund
has received the appropriate assets. Your proceeds can be wired to your bank
account. Armada Funds do not charge a fee to wire your funds; however, your
institution may charge a fee. IF YOU RECENTLY PURCHASED YOUR SHARES BY CHECK,
REDEMPTION PROCEEDS MAY NOT BE AVAILABLE UNTIL YOUR CHECK HAS CLEARED (WHICH MAY
TAKE UP TO 15 DAYS FROM YOUR DATE OF PURCHASE).

REDEMPTIONS IN KIND

We generally pay sale (redemption) proceeds in cash. However, under unusual
conditions that make the payment of cash unwise (and for the protection of the
Fund's remaining shareholders) we might pay all or part of your redemption
proceeds in liquid securities with a market value equal to the redemption price
(redemption in kind). It is highly unlikely that your shares would ever be
redeemed in kind, but if they were you would probably have to pay transaction
costs to sell the securities distributed to you, as well as taxes on any capital
gains from the sale as with any redemption. The Armada Tax Managed Equity Fund
may fund redemptions of $1 million or more with appreciated securities rather
than cash.

SUSPENSION OF YOUR RIGHT TO SELL YOUR SHARES

A Fund may suspend your right to sell your shares if the New York Stock Exchange
restricts trading, the SEC declares an emergency or for other reasons. More
information about this is in our Statement of Additional Information.

DISTRIBUTION OF FUND SHARES

Each Fund has adopted a distribution plan under Rule 12b-1, pursuant to the 1940
Act, that allows each Fund to pay distribution and service fees for the sale and
distribution of its shares, and for services provided to shareholders. Because
these fees are paid out of a Fund's assets continuously, over time these fees
will increase the cost of your investment and may cost you more than paying
other types of sales charges.

Distribution fees, as a percentage of average daily net assets are as follows:

* As of the printing of this prospectus, these Funds have not yet commenced
operations.

Each Fund makes distributions of capital gains, if any, at least annually. If
you own Fund shares on a Fund's record date, you will be entitled to receive the
distribution.

You will receive dividends and distributions in the form of additional Fund
shares unless you elect to receive payment in cash. To elect cash payment, you
must notify the Fund in writing prior to the date of the distribution. Your
election will be effective for dividends and distributions paid after the Fund
receives your written notice. To cancel your election, simply send the Fund
written notice.

FEDERAL TAXES

Each Fund contemplates declaring as dividends each year all or substantially all
of its taxable income, including its net capital gain (the excess of long-term
capital gain over short-term capital loss). Distributions attributable to the
net capital gain of a Fund will be taxable to you as long-term capital gain,
regardless of how long you have held your shares. Other Fund distributions
(other than exempt-interest dividends, discussed below) will generally be
taxable as ordinary income. You will be subject to income tax on Fund
distributions regardless of whether they are paid in cash or reinvested in
additional shares. You will be notified annually of the tax status of
distributions to you.

In the case of any Fund other than a money-market Fund, you should note that if
you purchase shares just before a distribution, the purchase price will reflect
the amount of the upcoming distribution, but you will be taxable on the entire
amount of the distribution received, even though, as an economic matter, the
distribution simply constitutes a return of capital. This is known as "buying
into a dividend."

You will recognize taxable gain or loss on a sale, exchange or redemption of
your shares, including an exchange for shares of another Fund, or an in-kind
redemption, based on the difference between your tax basis in the shares and the
amount you receive for them. (To aid in computing your tax basis, you generally
should retain your account statements for the periods during which you held
shares.) Any loss realized on shares held for six months or less will be treated
as a long-term capital loss to the extent of any capital gain dividends that
were received on the shares.

The one major exception to these tax principles is that distributions on, and
sales, exchanges and redemptions of, shares held in an IRA(or other
tax-qualified plan) will not be currently taxable.

It is expected that the Armada International Equity Fund will be subject to
foreign withholding taxes with respect to dividends or interest received from
sources in foreign countries. The Armada International Equity Fund may make an
election to treat a proportionate amount of such taxes as constituting a
distribution to each shareholder, which would allow each shareholder either (1)
to credit such proportionate amount of taxes against U.S. federal income tax
liability or (2) to take such amount as an itemized deduction.

The Armada Tax Exempt Money Market Fund, Armada Pennsylvania Tax Exempt Money
Market Fund, Armada Ohio Municipal Money Market Fund, Armada Ohio Tax Exempt
Bond Fund, Armada Pennsylvania Municipal Bond Fund, Armada National Tax Exempt
Bond Fund, and Armada Michigan Municipal Bond Fund (the "Tax Exempt Funds")
anticipate that substantially all of their income dividends will be "exempt
interest dividends," which are exempt from federal income taxes. However, some
dividends will be taxable, such as dividends that are derived from occasional
taxable investments, and in the case of other than money market Funds,
distributions of short and long-term capital gains. Interest on indebtedness
incurred by a shareholder to purchase or carry shares of any Tax Exempt Fund
generally will not be deductible for federal income tax purposes.

You should note that a portion of the exempt-interest dividends paid by the Tax
Exempt Funds may constitute an item of tax preference for purposes of
determining federal alternative minimum tax liability. Exempt-interest dividends
will also be considered along with other adjusted gross income in determining
whether any Social Security or railroad retirement payments received by you are
subject to federal income taxes.

If you receive an exempt-interest dividend with respect to any share and the
share is held by you for six months or less, any loss on the sale or exchange of
the share will be disallowed to the extent of such dividend amount.

The foregoing is only a summary of certain tax considerations under current law,
which may be subject to change in the future. Shareholders who are nonresident
aliens, foreign trusts or estates, or foreign corporations or partnerships, may
be subject to different United States federal income tax treatment. You should
consult your tax adviser for further information regarding federal, state, local
and/or foreign tax consequences relevant to your specific situation.

STATE AND LOCAL TAXES

Shareowners may also be subject to state and local taxes on distributions and
redemptions. State income taxes may not apply, however, to the portions of each
Fund's distributions, if any, that are attributable to interest on Federal
Securities or interest on securities of the particular state or localities
within the state. The Armada Pennsylvania Tax Exempt Money Market Fund and
Armada Pennsylvania Municipal Bond Fund intend to distribute income that is
exempt from Pennsylvania personal income taxes. The Armada Ohio Tax Exempt Bond
Fund and Armada Ohio Municipal Money Market Fund intend to distribute income
that is exempt from Ohio personal income taxes. The Armada Michigan Municipal
Bond Fund intends to distribute income that is exempt from Michigan income
taxes. Shareowners should consult their tax advisers regarding the tax status of
distributions in their state and locality.

Each Fund may invest a portion of its assets in securities that generate taxable
income for federal or state income taxes. Income exempt from federal tax may be
subject to state and local taxes. Any capital gains distributed by these Funds
may be taxable.

The Funds use a tax management technique known as "highest in, first out." Using
this technique, the portfolio holdings that have experienced the smallest gain
or largest loss are sold first in an effort to minimize capital gains and
enhance after-tax returns.

MORE INFORMATION ABOUT TAXES IS IN THE STATEMENT OF ADDITIONAL INFORMATION.

ADDITIONAL INFORMATION ABOUT THE FUNDS
- --------------------------------------

                  The following information supplements and should be read in
conjunction with the principal strategies and risk disclosure relating to the
Fund in the Prospectuses.

ARMADA INTERNATIONAL EQUITY FUND

                  The Fund seeks to achieve its investment objective by
investing, under normal market conditions, at least 80% of its total assets in
equity securities of foreign issuers. The Fund's assets normally will be
invested in the securities of issuers located in at least three foreign
countries. Foreign investments may also include debt obligations issued or
guaranteed by foreign governments or their agencies, authorities,
instrumentalities or political subdivisions, including a foreign state, province
or municipality. The Adviser does not presently intend to invest in common stock
of domestic companies.

                  The Fund will invest primarily in equity securities, including
common and preferred stocks, rights, warrants, securities convertible into
common stocks and American Depository Receipts ("ADRs") of companies included in
the Morgan Stanley Capital International Europe, Australia, Far East ("EAFE")
Index, a broadly diversified international index consisting of more than 1,000
equity securities of companies located in Australia, Austria, Belgium, Denmark,
Finland, France, Germany, Hong Kong, Ireland, Italy, Japan, Malaysia, the
Netherlands, New Zealand, Norway, Singapore, Spain, Sweden, Switzerland, and the
United Kingdom. The Fund, however, is not an "index" fund, and is neither
sponsored by nor affiliated with Morgan Stanley Capital International. The Fund
does not anticipate making investments in markets where, in the judgment of the
Adviser, property rights are not defined and supported by adequate legal
infrastructure.

                  More than 25% of the Fund's assets may be invested in the
securities of issuers located in the same country. Investment in a particular
country of 25% or more of the Fund's total assets will make the Fund's
performance more dependent upon the political and economic circumstances of that
country than a mutual fund more widely diversified among issuers in

                                      -2-

different countries. Criteria for determining the appropriate distribution of
investments among countries may include relative valuation, growth prospects,
and fiscal, monetary, and regulatory government policies. See "Additional
Information about Portfolio Instruments - Foreign Securities and Currencies"
below.

ARMADA SMALL CAP VALUE FUND

                  Under normal conditions, at least 80% of the value of the
Fund's total assets will be invested in equity securities of companies with
market capitalizations comparable to those of companies in the Russell 2000
Value Index. The Fund will be managed with a value approach, exhibiting
aggregate valuation characteristics such as price/earnings, price/book, and
price cash/flow ratios which are at a discount to the market averages.
Additional factors such as private market value, balance sheet strength, and
long term earnings potential are also considered in stock selection. See
"Special Risk Factors -- Small Capitalization Stocks" below.

ARMADA SMALL CAP GROWTH FUND

                  The Fund will normally invest at least 80% of its total assets
in equity securities of companies with stock market capitalizations comparable
to that of companies in the Russell 2000 Growth Index. The Adviser will seek
companies with above-average growth prospects. Factors considered in selecting
such issuers include participation in a fast growing industry, a strategic niche
position in a specialized market, and fundamental value. The Adviser will also
consider the relationship between price and book value, and other factors such
as trading volume and bid-ask spreads in an effort to allow the Fund to achieve
diversification. See "Special Risk Factors -- Small Capitalization Stocks"
below.

         Special Risk Factors for Small Capitalization Stocks

                  Securities held by the Small Cap Value and Small Cap Growth
Funds generally will be issued by public companies with small capitalizations
relative to those which predominate the major market indices, such as the S&P's
500 or the Dow Jones Industrial Average. Securities of these small companies may
at times yield greater returns on investment than stocks of larger, more
established companies as a result of inefficiencies in the marketplace. Small
capitalization companies are generally not as well-known to investors and have
less of an investor following than larger companies.

                  However, the positions of small capitalization companies in
the market may be more tenuous because they typically are subject to a greater
degree of change in earnings and business prospects than larger, more
established companies. In addition, securities of small capitalization companies
are traded in lower volume than those of larger companies and may be more
volatile. As a result, the Funds may be subject to greater price volatility than
a fund consisting of large capitalization stocks. By maintaining a broadly
diversified portfolio, the sub-adviser will attempt to reduce this volatility.

ARMADA EQUITY GROWTH FUND

                  Under normal conditions, at least 80% of the Fund's total
assets will be invested in a diversified portfolio of common stocks and
securities convertible into common stocks with large stock market
capitalizations comparable to that of companies in the S&P 500. The Fund's
Adviser selects common stocks based on a number of factors, including
historical and projected earnings growth, earnings quality and liquidity, each
in relation to the market price of the stock. Stocks purchased for the Fund
generally will be listed on a national securities exchange or will be unlisted
securities with an established over-the-counter market.

ARMADA TAX MANAGED EQUITY FUND

                  The Fund invests primarily in common stocks. The Fund will use
several methods to reduce the impact of federal and state income taxes on
investment income and realized capital gains distributed by the Fund.

                  The Fund will seek to distribute relatively low levels of
taxable investment income by investing in stocks with low dividend yields.

                  The Fund will endeavor to hold taxes on realized capital gains
to a minimum by investing primarily in the securities of companies with above
average earnings predictability and stability which the Fund expects to hold for
several years. The Fund will generally seek to avoid realizing short-term
capital gains, and expects to have a relatively low overall portfolio turnover
rate. When the Fund sells appreciated securities, it will attempt to select the
share lots with the highest cost basis in order to hold realized capital gains
to a minimum. The Fund may, when consistent with its overall investment
approach, sell depreciated securities to offset realized capital gains.

                  Although the Fund expects to use some or all of the foregoing
methods in seeking to reduce the impact of federal and state income taxes on the
Fund's dividends and distributions, portfolio management decisions will also be
based on non-tax considerations when appropriate. Certain equity and other
securities held by the Fund will produce ordinary taxable income on a regular
basis. The Fund may also sell a particular security, even though it may realize
a short-term capital gain, if the value of that security is believed to have
reached its peak or is expected to decline before the Fund would have held it
for the long-term holding period. The Fund may also be required to sell
securities in order to generate cash to pay expenses or satisfy shareholder
redemptions.

                  Accordingly, while the Fund seeks to minimize the effect of
taxes on its dividends and distributions, the Fund is not a tax-exempt fund, and
may be expected to distribute taxable income and realize capital gains from time
to time.

                  The Fund will normally invest at least 80% of its total
assets in common stocks and other equity securities. The Fund's Adviser
selects common stocks based on a number of factors, including historical and
projected long-term earnings growth, earnings



                                      -4-
<PAGE>   227

quality and liquidity, each in relation to the market price of the stock. Stocks
purchased for the Fund generally will be listed on a national securities
exchange or will be unlisted securities with an established over-the-counter
market. The Fund may invest up to 5% of its net assets in each of the following
types of equity securities: preferred stocks; securities convertible into common
stocks; rights; and warrants.

                  The Fund's long-term investment horizon is reflected in its
low portfolio turnover investment approach. The portfolio turnover rate reflects
the frequency with which securities are purchased and sold within the Fund's
portfolio. The Fund's annual portfolio turnover is not expected to exceed 25%
under normal market conditions. (A rate of turnover of 100% could occur, for
example, if all the securities held by the Fund are replaced within a period of
one year.) When a Fund sells securities realizing gains, tax laws require that
such gains be distributed to investors every year. As a result, such investors
are taxed on their pro-rata shares of the gains. By attempting to minimize
portfolio turnover, the Fund will generally have a low turnover rate. It is
impossible to predict the impact of such a strategy on the realization of gains
or losses for the Fund. For example, the Fund may forego the opportunity to
realize gains or reduce losses as a result of this policy.

                  The Fund may be appropriate for investors who seek capital
appreciation and whose tax status under federal and state regulations increase
the importance of such strategies.

ARMADA CORE EQUITY FUND

                  The Fund seeks to achieve its objective by investing in a
diversified portfolio of common stocks of issuers with large capitalizations
comparable to that of companies in the S&P 500. The Fund normally invests in
three types of equity securities: (i) growth securities, defined as common
stocks having a five-year annual earnings-per-share growth rate of 10% or more,
with no decline in the annual earnings-per-share rate during the last five
years; (ii) securities with low price-to-earnings ratios (i.e., at least 20%
below the average of the companies included in the S&P 500); and (iii)
securities that pay high dividend yields (i.e., at least 20% above such
average). The Fund will normally invest 20% to 50% of its total assets in each
of these three types of equity securities. The Fund is fully invested at all
times.

                  The S&P 500 is an index composed of approximately 500 common
stocks, most of which are listed on the New York Stock Exchange (the "NYSE").
The Sub-adviser believes that the S&P 500 is an appropriate benchmark for the
Fund because it is diversified, familiar to many investors and widely accepted
as a reference for common stock investments.

                  Standard & Poor's Ratings Group is not a sponsor of, or in any
way affiliated with, the Fund.

ARMADA EQUITY INDEX FUND

                  The S&P 500 is composed of approximately 500 common stocks,
most of which are listed on the NYSE. S&P selects the stocks for the S&P 500 on
a statistical basis. As of



                                      -5-
<PAGE>   228

May 31, 1999, the stocks in the S&P 500 had an average market capitalization of
94.1 billion and the total market capitalization of all U.S. common stocks was
10.7 trillion. "Market capitalization" of a company is the market price per
share of stock multiplied by the number of shares outstanding. The Adviser
believes that the S&P 500 is an appropriate benchmark for the Fund because it is
diversified, familiar to many investors and widely accepted as a reference for
common stock investments.

                  The Fund will normally invest substantially all of its total
assets in the stocks that comprise the S&P 500 in approximately the same
percentages as the stocks represent in the index. The Fund may also acquire
derivative instruments designed to replicate the performance of the S&P 500,
such as S&P 500 stock index futures contracts or Standard & Poor's Depository
Receipts. The Fund may invest in all the approximately 500 stocks comprising the
S&P 500, or it may use a statistical sampling technique by selecting
approximately 90% of the stocks listed in the index. The Fund will only purchase
a security that is included in the S&P 500 at the time of such purchase. The
Fund, may, however, temporarily continue to hold a security that has been
deleted from the S&P 500 pending the rebalancing of the Fund's portfolio. The
Fund is not required to buy or sell securities solely because the percentage of
its assets invested in index stocks changes when the market value of its
holdings increases or decreases. In addition, the Fund may omit or remove an
index stock from its portfolio if the Adviser believes the stock to be
insufficiently liquid or believes the merit of the investment has been
substantially impaired by extraordinary events or financial conditions. With
respect to the remaining portion of its net assets, the Fund may hold temporary
cash balances which may be invested in U.S. government obligations and money
market investments. In extraordinary circumstances, the Fund may exclude a stock
listed on the index from its holdings or include a similar stock in its place if
it believes that doing so will help achieve its investment objective. The Fund
also may enter into repurchase agreements, reverse repurchase agreements, and
lend its portfolio securities.

                  While there can be no guarantee that the Fund's investment
results will precisely match the results of the S&P 500, the Adviser believes
that, before deduction of operating expenses, there will be a very high
correlation between the returns generated by the Fund and the S&P 500. The Fund
will attempt to achieve a correlation between the performance of its asset
portfolio and that of the S&P 500 of at least 95% before deduction of operating
expenses. A correlation of 100% would indicate perfect correlation, which would
be achieved when the Fund's net asset value, including the value of its dividend
and capital gains distributions, increases or decreases in exact proportion to
changes in the index. The Fund's ability to correlate its performance with the
S&P 500, however, may be affected by, among other things, changes in securities
markets, the manner in which S&P calculates its index, and the timing of
purchases and redemptions. The Adviser monitors the correlation of the
performance of the Fund in relation to the index under the supervision of the
Board of Trustees. The Fund intends to actively rebalance its portfolio to
achieve high correlation of performance with the S&P 500. To reduce transaction
costs and minimize shareholders' current capital gains liability, the Fund's
investment portfolio will not be automatically rebalanced to reflect changes in
the S&P 500. In the unlikely event that a high correlation is not achieved, the
Board of Trustees will take appropriate steps based on the reasons for the lower
than expected correlation.

         The Indexing Approach

                  The Fund is not managed in a traditional sense, that is, by
making discretionary judgments based on analysis of economic, financial and
market conditions. Under ordinary circumstances, stocks will only be eliminated
from or added to the Fund to reflect additions to or deletions from the S&P 500
(including mergers or changes in the composition of the index), to raise cash to
meet withdrawals, or to invest cash contributions. Accordingly, sales may result
in losses that may not have been realized if the Fund were actively managed and
purchases may be made that would not have been made if the Fund were actively
managed. Adverse events, such as reported losses, dividend cuts or omissions,
legal proceedings and defaults will not normally result in the sale of a common
stock. The Fund will remain substantially fully invested in common stocks and
equity derivative instruments whether stock prices are rising or falling.

                  The Adviser believes that the indexing approach should involve
less portfolio turnover, notwithstanding periodic additions to and deletions
from the S&P 500, and thus lower brokerage costs, transfer taxes and operating
expenses, than in more traditionally managed funds, although there is no
assurance that this will be the case. The costs and other expenses incurred in
securities transactions, apart from any difference between the investment
results of the Fund and those of the S&P 500, may cause the return of the Fund
to be lower than the return of the index.

                  The inclusion of a security in the S&P 500 in no way implies
an opinion by S&P as to its attractiveness as an investment. S&P is not a
sponsor of, or in any way affiliated with, the Fund.

                  The common stock of National City Corporation, the parent
company of the Adviser, is included in the S&P 500. Like the other stocks in the
S&P 500, the Fund will invest in the common stock of National City Corporation
in approximately the same proportion as the percentage National City Corporation
common stock represents in the S&P 500. As of May 31, 1999, National City
Corporation common stock represented 1.7% of the index.

ARMADA EQUITY INCOME FUND

                  The Fund will normally invest at least 80% of the value of its
total assets in income-producing common stocks and securities convertible into
common stocks assigned a rating of Ba/BB or higher by Moody's, S&P, Fitch or
Duff. The Fund's Adviser will generally attempt to select securities that
provide a higher yield than that of the general market and will generally
dispose of securities whose yields approach a market yield or that otherwise
fail to satisfy investment criteria.

ARMADA BALANCED ALLOCATION FUND

                  The Fund may invest in any type or class of security. The Fund
normally invests in common stocks, fixed income securities, securities
convertible into common stocks (i.e., warrants, convertible preferred stock,
fixed rate preferred stock,



                                      -7-
<PAGE>   230

convertible fixed income securities, options and rights) and cash equivalent
securities. The Fund intends to invest 50% to 70% of its net assets in common
stocks and securities convertible into common stocks, 25% to 55% of its net
assets in fixed income securities and up to 30% of its net assets in cash and
cash equivalents. Of these investments, no more than 20% of the Fund's total
assets will be invested in foreign securities.

                  The Fund holds common stocks primarily for the purpose of
providing long-term growth of capital. When selecting stocks for the Fund, the
Adviser will consider primarily their potential for long-term capital
appreciation. The Fund intends to invest predominantly in those companies which
are growth-oriented and have exhibited consistent, above-average growth in
revenues and earnings.

                  The Fund invests the fixed income portion of its portfolio of
investments in a broad range of investment grade debt securities which are rated
at the time of purchase within the four highest rating categories assigned by
Moody's, S&P, Fitch or Duff (defined under "Ratings Criteria" below). These
fixed income securities will consist of bonds, debentures, notes, zero coupon
securities, asset-backed securities, state, municipal and industrial revenue
bonds, obligations issued or guaranteed by the U.S. government or its agencies
or instrumentalities, certificates of deposit, time deposits, high quality
commercial paper, bankers' acceptances and variable amount master demand notes.
In addition, a portion of the Fund's assets may be invested from time to time in
first mortgage loans and participation certificates in pools of mortgages issued
or guaranteed by the U.S. government or its agencies or instrumentalities. Some
fixed income securities may have warrants or options attached.

ARMADA TOTAL RETURN ADVANTAGE FUND

                  The Fund will normally invest at least 80% of the value of its
total assets in debt securities of all types, although up to 20% of the value of
its total assets may be invested in preferred stocks and other investments.
Under normal market conditions, the Fund maintains an average dollar-weighted
portfolio maturity of four to twelve years.

                  Although the Total Return Advantage Fund normally invests
substantially all of its assets in investment grade debt securities, it may
invest up to 15% of its net assets in non-rated securities and securities rated
below investment grade (commonly referred to as "junk bonds"). For a discussion
of risk factors relating to such securities, see "Risks Related to Lower Rated
Securities Which May Be Purchased by the Total Return Advantage Fund." See
"Additional Information about Portfolio Instruments - Risks Related to Lower
Rated Securities Which May Be Purchased by the Total Return Advantage Fund."

ARMADA BOND FUND

                  The Fund seeks to achieve its objective by normally investing
at least 80% of its total assets in investment grade fixed-income securities.
The Fund uses the Lehman Aggregate Bond


                                      -8-
<PAGE>   231

Index ("Lehman Aggregate") as its performance benchmark. The average maturity of
the Fund will be from four to twelve years.

ARMADA INTERMEDIATE BOND FUND

                  The Fund normally invests at least 80% of the value of its
total assets in debt securities of all types, although up to 20% of the value of
its total assets may be invested in preferred stocks and other investments. The
Fund normally maintains an average dollar-weighted portfolio maturity of three
to ten years. The Fund uses the Lehman Intermediate Government/Corporate Bond
Index as its performance benchmark.

ARMADA GNMA FUND

                  The Fund seeks to achieve its objective by normally investing
primarily (at least 80% of its total assets under normal conditions) in mortgage
pass-through securities guaranteed by the Government National Mortgage
Association (GNMA). Any remaining assets may consist of other investment grade
fixed income securities. GNMA was established as an instrumentality of the U.S.
government to supervise and finance certain types of activities. Under normal
market conditions, the estimated average life of the GNMA Fund's holdings of
mortgage pass-through and mortgage-backed securities will range between three
and 10 years. The Fund employs the Lehman GNMA Index as its performance
benchmark.

ARMADA ENHANCED INCOME FUND

                  The Fund will normally invest at least 80% of the value of its
total assets in investment grade debt securities of all types. However, up to
20% of the value of its total assets may be invested in preferred stocks and
other investments. In making investment decisions, the Fund's adviser will focus
on a number of factors, including yield to maturity, maturity, quality and the
outlook for specific issuers and market sectors. The Fund normally intends to
maintain an average dollar-weighted portfolio maturity for its debt securities
of from 1 to 5 years. The two components of total rate of return are current
income and change in the value of portfolio securities. The Merrill Lynch 1-3
Year Government/Corporate Bond Index is composed of U.S. Treasury and Agency
Bonds and U.S. fixed coupon investment grade corporate bonds that mature in one
to three years. The average dollar-weighted maturity of the Index is generally
from 2-1/2 to 3 years. The Index is unmanaged, and its total rate of return does
not reflect the expenses that a mutual fund normally incurs. The Fund's
objective refers to a return after deduction of Fund expenses.

ARMADA OHIO TAX EXEMPT BOND FUND

                  The Fund seeks to achieve its objective by investing
substantially all of its assets in a portfolio of obligations issued by or on
behalf of states, territories and possessions of the United States, the District
of Columbia and their political subdivisions, agencies, instrumentalities and
authorities, the interest on which, in the opinion of counsel issued on the date
of the issuance thereof, is exempt from regular federal income tax (Municipal
Securities).



                                      -9-
<PAGE>   232
                  The Fund normally will invest at least 80% of the value of its
total assets in Municipal Securities. This policy is fundamental and may not be
changed without the affirmative vote of the holders of a majority of the Fund's
outstanding shares (as defined under "Shareholder Vote" below). In addition, the
Fund will normally invest at least 80% of the value of its total assets in
Municipal Securities issued by or on behalf of the State of Ohio, political
subdivisions thereof, or agencies or instrumentalities of the State or its
political subdivisions (Ohio Municipal Securities). Dividends paid by the Fund
which are derived from interest properly attributable to Ohio Municipal
Securities will be exempt from regular federal income tax and Ohio personal
income tax. Dividends derived from interest on Municipal Securities of other
governmental issuers will be exempt from regular federal income tax but may be
subject to Ohio personal income tax. See "Additional Tax Information Concerning
the Ohio Tax Exempt Bond Fund."

ARMADA PENNSYLVANIA MUNICIPAL BOND FUND

                  The Fund seeks to achieve its objective by investing
substantially all of its assets in Municipal Securities issued by or on behalf
of the Commonwealth of Pennsylvania and its political subdivisions and financing
authorities, obligations of the United States, including territories and
possessions of the United States, the income from which is, in the opinion of
counsel, exempt from regular federal income tax and Pennsylvania state income
tax imposed upon non-corporate taxpayers, and securities of money market
investment companies that invest primarily in such securities (Pennsylvania
Municipal Securities).

                  The Fund will normally be fully invested in Pennsylvania
Municipal Securities. This policy is fundamental and may not be changed without
the affirmative vote of the holders of a majority of the Fund's outstanding
shares (as defined under "Shareholder Vote"). Dividends paid by the Fund which
are derived from interest properly attributable to Pennsylvania Municipal
Securities will be exempt from regular federal income tax and Pennsylvania
personal income tax. Dividends derived from interest on Municipal Securities of
other governmental issuers will be exempt from regular federal income tax but
may be subject to Pennsylvania personal income tax. See "Additional Tax
Information concerning the Pennsylvania Municipal Bond Fund."

ARMADA NATIONAL TAX EXEMPT BOND FUND

                  The Fund will normally invest at least 80% of the value of its
total assets will be invested in Municipal Securities. This policy is
fundamental and may not be changed without the affirmative vote of the holders
of a majority of the Fund's outstanding shares (as defined under "Shareholder
Vote").

         Armada Ohio Tax Exempt Bond, Pennsylvania Municipal Bond and National
Tax Exempt Bond Funds

                  Although each Fund's average weighted maturity will vary in
light of current market and economic conditions, the comparative yields on
instruments with different maturities, and other factors, the Ohio Tax Exempt
Bond and Pennsylvania Municipal Bond and National Tax Exempt Bond Funds
anticipate that they will maintain a dollar-weighted average portfolio maturity
of three to ten years.



                                      -10-
<PAGE>   233

                  For temporary defensive or liquidity purposes when, in the
opinion of the Funds' adviser, Ohio Municipal Securities or Pennsylvania
Municipal Securities of sufficient quality, as the case may be, are not readily
available, the Ohio Tax Exempt Bond and Pennsylvania Municipal Bond Funds may
invest up to 100% of their assets in other Municipal Securities and in taxable
securities.

                  All Funds may hold up to 100% of their assets in uninvested
cash reserves, pending investment, during temporary defensive periods; however,
uninvested cash reserves will not earn income.

                  Each Fund may invest in other investments as described below
under "Other Investment Policies" including stand-by commitments, variable and
floating rate obligations, certificates of participation, other investment
companies, illiquid securities, Taxable Money Market Instruments (as defined
below), zero coupon obligations and repurchase agreements and engage in
when-issued transactions.

         Special Risk Considerations

         Armada Ohio Tax Exempt Bond, Pennsylvania Municipal Bond, National Tax
Exempt Bond Funds

                  The Ohio Tax Exempt and Pennsylvania Tax Exempt Bond Funds are
classified as non-diversified under the 1940 Act. Investment return on a
non-diversified portfolio typically is dependent upon the performance of a
smaller number of securities relative to the number held in a diversified
portfolio. Consequently, the change in value of any one security may affect the
overall value of a non-diversified portfolio more than it would a diversified
portfolio, and thereby subject the market-based net asset value per share of the
non-diversified portfolio to greater fluctuations. In addition, a
non-diversified portfolio may be more susceptible to economic, political and
regulatory developments than a diversified investment portfolio with similar
objectives may be.

                  Although (i) all of the Funds may invest 25% or more of their
respective net assets in Municipal Securities the interest on which is paid
solely from revenues of similar projects, (ii) the Ohio Tax Exempt Bond and
National Tax Exempt Bond Funds may invest up to 20% of their respective total
assets in private activity bonds (described below) and taxable investments,
(iii) the Pennsylvania Municipal Bond Fund may invest up to 100% of its total
assets in Pennsylvania private activity bonds and (iv) the National Tax Exempt
Bond Fund may invest 25% or more of its net assets in Municipal Securities whose
issues are in the same state, the Funds do not presently intend to do so unless,
in the opinion of the adviser, the investment is warranted. To the extent that a
Fund's assets are invested in such investments, the Fund will be subject to the
peculiar risks presented by the laws and economic conditions relating to such
projects and private activity bonds to a greater extent than it would be if its
assets were not so invested.

                  See "Municipal Securities," "Special Considerations Regarding
Investment in Ohio Municipal Securities," and "Special Considerations Regarding
Investment in Pennsylvania Municipal Securities" below.

ARMADA OHIO MUNICIPAL MONEY MARKET FUND

                  The Fund seeks to achieve its objective by investing
substantially all of its assets in Municipal Securities (defined below) issued
by or on behalf of the State of Ohio, political subdivisions thereof or agencies
or instrumentalities of the State or its political subdivisions (Ohio Municipal
Securities).

                  The Fund will normally invest at least 80% of the value of its
total assets in Ohio Municipal Securities. This policy is fundamental and may
not be changed without the affirmative vote of the holders of a majority of the
Fund's outstanding shares (as defined under "Shareholder Vote"). Dividends paid
by the Fund which are derived from interest properly attributable to Ohio
Municipal Securities will be exempt from regular federal income tax and Ohio
personal income tax. Dividends derived from interest on Municipal Securities of
other governmental issuers will be exempt from regular federal income tax but
may be subject to Ohio personal income tax. The Fund may invest up to 100% of
its assets in Municipal Securities known as private activity bonds (described
below) the interest on which is an item of tax preference for purposes of the
federal alternative minimum tax ("AMT Paper"). The Fund may also invest up to
100% of its assets in non-Ohio Municipal Securities and in taxable securities,
during temporary defensive periods when, in the opinion of the Adviser, Ohio
Municipal Securities of sufficient quality are unavailable.

                  The Ohio Municipal Money Market Fund is concentrated in
securities issued by the State of Ohio or entities within the State of Ohio, and
therefore, investment in the Fund may be riskier than an investment in other
types of money market funds.

                  See "Special Risk Considerations of the Ohio Municipal Money
Market Fund" below.

ARMADA PENNSYLVANIA TAX EXEMPT MONEY MARKET FUND

                  The Fund seeks to achieve its objective by investing
substantially all of its assets in Municipal Securities defined below issued by
or on behalf of the Commonwealth of Pennsylvania and its political subdivisions
and financing authorities, and obligations of the United States, including
territories and possessions of the United States, the income from which, in the
opinion of bond counsel, is exempt from regular federal income tax and
Pennsylvania income tax imposed upon non-corporate taxpayers (Pennsylvania
Municipal Securities).

                  As a matter of fundamental policy, the Fund normally invests
its assets so that at least 80% of its annual interest income is not only exempt
from regular federal income tax and Pennsylvania personal income taxes, but is
not considered a preference item for purposes of the federal alternative minimum
tax. However, the Fund may invest up to 100% of its assets in non-Pennsylvania
Municipal Securities and in taxable securities, during temporary defensive
periods when, in the opinion of the Adviser, Pennsylvania Municipal Securities
of sufficient quality are unavailable.

                  The Pennsylvania Tax Exempt Money Market Fund is concentrated
in securities issued by the Commonwealth of Pennsylvania or entities within the

         Special Risk  Considerations -- Ohio Municipal Money Market,
Pennsylvania Tax Exempt Money Market and the Tax Exempt Money Market Funds

         Although the Tax Exempt Money Market Fund may invest 25% or more of its
net assets in Municipal Securities whose issuers are in the same state and the
Ohio Municipal Money Market, Pennsylvania Tax Exempt Money Market and Tax Exempt
Money Market Funds may invest 25% or more of their respective net assets in
Municipal Securities the interest on which is paid solely from revenues of
similar projects, the Funds do not presently intend to do so unless in the
opinion of the Adviser the investment is warranted. The Ohio Municipal Money
Market Fund may invest up to 100% of its assets in private activity bonds. In
addition, although the Pennsylvania Tax Exempt Money Market and Tax Exempt Money
Market Funds may invest up to 20% of their respective total assets in private
activity bonds (described below) and taxable investments, these Funds do not
currently intend to do so unless in the opinion of the Adviser the investment is
warranted. To the extent that a Fund's assets are invested in Municipal
Securities that are payable from the revenues of similar projects or are issued
by issuers located in the same state or are invested in private activity bonds,
the Fund will be subject to the peculiar risks presented by the laws and
economic conditions relating to such states, projects and bonds to a greater
extent than it would be if its assets were not so invested.

ARMADA MONEY MARKET FUND

                  The Fund seeks to achieve its objective by investing in "money
market" instruments such as certificates of deposit and other obligations issued
by domestic and foreign banks, and commercial paper (including variable and
floating rate instruments) rated high quality by an unaffiliated Rating Agency,
or determined to be of comparable quality by the Adviser. The Money Market Fund
may also invest in obligations issued or guaranteed by the U.S. government, its
agencies or instrumentalities, and repurchase agreements issued by financial
institutions such as banks and broker-dealers.

ARMADA GOVERNMENT MONEY MARKET FUND

                  The Fund seeks to achieve its objective by investing in
obligations issued or guaranteed as to payment of principal and interest by the
U.S. government, its agencies or instrumentalities, and repurchase agreements
issued by financial institutions such as banks and broker-dealers. The Fund is
currently rated by S&P.

ARMADA TREASURY MONEY MARKET FUND

         The Fund seeks to achieve its objective by investing exclusively in
direct obligations of the U.S. Treasury, such as Treasury bills and notes, and
investment companies that invest exclusively in such obligations. The Fund is
currently rated by S&P.

ARMADA MID CAP GROWTH FUND

                  The Fund normally will invest at least 80% of the value of its
total assets in common stocks and securities convertible into common stocks of
companies believed by the Adviser to be characterized by sound management and
the ability to finance expected long-term growth.  The Fund normally will invest
at least 80% of the value of its total assets in common stocks and securities
convertible into common stocks of companies with market capitalizations
comparable to companies in the Russell Mid Cap Growth Index. The Fund may also
invest up to 20% of the value of its total assets in preferred stocks, corporate
bonds, notes, units of real estate investment trusts, warrants, and short-term
obligations (with maturities of 12 months or less) consisting of commercial
paper (including variable amount master demand notes), bankers' acceptances,
certificates of deposit, repurchase agreements, obligations issued or guaranteed
by the U.S. government or, its agencies or instrumentalities, and demand and
time deposits of domestic and foreign banks and savings and loan associations.
The Fund may also hold securities of other investment companies and depository
or custodial receipts representing beneficial interests in any of the foregoing
securities.

                  Subject to the foregoing policies, the Fund may also invest up
to 25% of its net assets in foreign securities either directly or through the
purchase of American Depository Receipts ("ADRs"), European Depository Receipts
("EDRs"), Global Depository Receipts ("GDRs") and other similar global
instruments, and may also invest in securities issued by


                                      -14-
<PAGE>   237

foreign branches of U.S. banks and foreign banks, Canadian commercial paper and
in U.S. dollar-denominated commercial paper of a foreign issuer.

                  The Fund anticipates investing in growth-oriented,
medium-sized companies. Medium-sized companies are considered to be those with a
market capitalization comparable to companies in the Russell Mid Cap Growth
Index. Investments will be in companies that have typically exhibited
consistent, above-average growth in revenues and earnings, strong management,
and sound and improving financial fundamentals. Often, these companies are
market or industry leaders, have excellent products and/or services, and exhibit
the potential for growth. Primary holdings of the Fund are in companies that
participate in long-term growth industries, although these will be supplemented
by holdings in non-growth industries that exhibit the desired characteristics.

                  Consistent with the foregoing, the Fund will focus its
investments in those companies and types of companies that the Adviser believes
will enable the Fund to achieve its investment objective.

ARMADA LARGE CAP ULTRA FUND

                  The Large Cap Ultra Fund normally will invest at least 80% of
the value of its total assets in common stocks and securities convertible into
common stocks of companies believed by the Investment Adviser to be
characterized by sound management and the ability to finance expected long-term
growth and with market capitalizations comparable to companies in the Standard &
Poor's Barra Growth Index. The Large Cap Ultra Fund may also invest up to 20% of
the value of its total assets in preferred stocks, corporate bonds, notes, units
of real estate investment trusts, warrants, and short-term obligations (with
maturities of 12 months or less) consisting of commercial paper (including
variable amount master demand notes), bankers' acceptances, certificates of
deposit, repurchase agreements, obligations issued or guaranteed by the U.S.
Government or its agencies or instrumentalities, and demand and time deposits of
domestic and foreign banks and savings and loan associations. The Large Cap
Ultra Fund may also hold securities of other investment companies and depository
or custodial receipts representing beneficial interests in any of the foregoing
securities.

                  Subject to the foregoing policies, the Large Cap Ultra Fund
may also invest up to 25% of its net assets in foreign securities either
directly or through the purchase of American depository receipts ("ADRs") or
European depository receipts ("EDRs") and may also invest in securities issued
by foreign branches of U.S. banks and foreign banks, CCP, and in U.S.
dollar-denominated commercial paper of a foreign issuer.

                  The Large Cap Ultra Fund anticipates investing in
growth-oriented companies with large market capitalization, defined as
capitalization comparable to companies in the Standard & Poor's Barra Growth
Index. The Large Cap Ultra Fund will invest in companies that have typically
exhibited consistent, above-average growth in revenues and earnings, strong
management, and sound and improving financial fundamentals. Often, these
companies are



                                      -15-
<PAGE>   238

market or industry leaders, have excellent products and/or services, and exhibit
the potential for growth. Core holdings of the Large Cap Ultra Fund are in
companies that participate in long-term growth industries, although these will
be supplemented by holdings in non-growth industries that exhibit the desired
characteristics.

                  Consistent with the foregoing, the Large Cap Ultra Fund will
focus its investments in those companies and types of companies that the
Investment Adviser believes will enable such Fund to achieve its investment
objective.

ARMADA U.S. GOVERNMENT INCOME FUND

                  The Fund will normally invest at least 80% of its total assets
in obligations issued or guaranteed by the U.S. government or its agencies or
instrumentalities, although up to 20% of the value of its total assets may be
invested in debt securities and preferred stocks of non-governmental issuers.
The Fund also may invest up to 20% of its total assets in mortgage-related
securities issued by non-Governmental entities and in other securities described
below. The Fund anticipates that it will acquire securities with average
remaining maturities of 3 to 10 years.

                  The types of U.S. government obligations, including
mortgage-related securities, invested in by the Fund will include obligations
issued or guaranteed as to payment of principal and interest by the full faith
and credit of the U.S. Treasury, such as Treasury bills, notes and bonds,
Stripped Treasury Obligations and government securities.

                  The Fund may also hold short-term obligations (with maturities
of 12 months or less) consisting of domestic and foreign commercial paper
(including variable amount master demand notes), rated at the time of purchase
within the top two rating categories assigned by a Rating Agency or, if unrated,
which the Adviser deems present attractive opportunities and are of comparable
quality, bankers' acceptances, certificates of deposit and time deposits of
domestic and foreign branches of U.S. banks and foreign banks, and repurchase
and reverse repurchase agreements. The Fund may also invest in corporate debt
securities which are rated at the time of purchase within the top four rating
categories assigned by a Rating Agency or, if unrated, which the Adviser deems
present attractive opportunities and are of comparable quality.

ARMADA MICHIGAN MUNICIPAL BOND FUND

                  As a fundamental policy, the Fund will normally invest at
least 80% of its net assets in a portfolio of securities exempt from Michigan
state taxes. The Fund may invest up to 100% of its assets in private activity
bonds which may be treated as a special tax preference item under the federal
alternative minimum tax.



                                      -16-
<PAGE>   239

                  "Michigan Municipal Securities" include debt obligations,
consisting of notes, bonds and commercial paper, issued by or on behalf of the
State of Michigan, its political subdivisions, municipalities and public
authorities, the interest on which is, in the opinion of bond counsel to the
issuer, exempt from federal income tax and Michigan state income taxes (but may
be treated as a preference item for individuals for purposes of the federal
alternative minimum tax) and debt obligations issued by the government of Puerto
Rico, the U.S. territories and possessions of Guam, the U.S. Virgin Islands or
such other governmental entities whose debt obligations, either by law or
treaty, generate interest income which is exempt from federal and Michigan state
income taxes.

                  The Fund normally will be invested in long-term Michigan
Municipal Securities and the average weighted maturity of such investments will
be 2 to 10 years, although the Fund may invest in Michigan Municipal Securities
of any maturity and the Adviser may extend or shorten the average weighted
maturity of its portfolio depending upon anticipated changes in interest rates
or other relevant market factors. In addition, the average weighted rating of
the Fund's portfolio may vary depending upon the availability of suitable
Michigan Municipal Securities or other relevant market factors.

                  The Fund invests in Michigan Municipal Securities which are
rated at the time of purchase within the four highest rating categories assigned
by a Rating Agency or, in the case of notes, tax-exempt commercial paper or
variable rate demand obligations, rated within the two highest rating categories
assigned by a Rating Agency. The Fund may also purchase Michigan Municipal
Securities which are unrated at the time of purchase but are determined to be of
comparable quality by the Adviser pursuant to guidelines approved by the Trust's
Board of Trustees. The applicable Michigan Municipal Securities ratings are
described in Appendix A.

                  Interest income from certain types of municipal securities may
be subject to federal alternative minimum tax. The Fund will not treat these
bonds as "Michigan Municipal Securities" for purposes of measuring compliance
with the 80% and 65% tests described above. To the extent the Fund invests in
these bonds, individual shareholders, depending on their own tax status, may be
subject to alternative minimum tax on that part of the Fund's distributions
derived from these bonds.

                  The Fund may invest in taxable obligations if, for example,
suitable tax-exempt obligations are unavailable or if acquisition of U.S.
government or other taxable securities is deemed appropriate for temporary
defensive purposes as determined by the Adviser to be warranted due to market
conditions. Such taxable obligations consist of government securities,
certificates of deposit, time deposits and bankers' acceptances of selected
banks, commercial paper meeting the Fund's quality standards for tax-exempt
commercial paper (as described above), and such taxable obligations as may be
subject to repurchase agreements. These



                                      -17-
<PAGE>   240

obligations are described further in the Statement of Additional Information.
Under such circumstances and during the period of such investment, the Fund may
not achieve its stated investment objective.

                  Because the Fund invests primarily in securities issued by the
State of Michigan and its political subdivisions, municipalities and public
authorities, the Fund's performance is closely tied to the general economic
conditions within the state as a whole and to the economic conditions within
particular industries and geographic areas represented or located within the
state. However, the Fund attempts to diversify, to the extent the Adviser deems
appropriate, among issuers and geographic areas in the State of Michigan.

                  The Fund is classified as a "non-diversified" investment
company, which means that the amount of assets of the Fund that may be invested
in the securities of a single issuer is not limited by the 1940 Act.
Nevertheless, the Fund intends to conduct its operations so as to qualify as a
"regulated investment company" for purposes of the Internal Revenue Code of
1986, as amended (the "Code"). The Code requires that, at the end of each
quarter of a fund's taxable year, (i) at least 50% of the market value of its
total assets be invested in cash, U.S. government securities, securities of
other regulated investment companies and other securities, with such other
securities of any one issuer limited for the purposes of this calculation to an
amount not greater than 5% of the value of the fund's total assets and 10% of
the outstanding voting securities of such issuer, and (ii) not more than 25% of
the value of its total assets be invested in the securities of any one issuer
(other than U.S. government securities or the securities of other regulated
investment companies). Since a relatively high percentage of the Fund's assets
may be invested in the obligations of a limited number of issuers, some of which
may be within the same economic sector, the Fund's portfolio securities may be
more susceptible to any single economic, political or regulatory occurrence than
the portfolio securities of a diversified investment company.

         See "Special Considerations Regarding Investment in Michigan Municipal
Securities" below.

ARMADA TREASURY PLUS MONEY MARKET FUND

         The Fund will only purchase "eligible securities" that present minimal
credit risks as determined by the Adviser pursuant to guidelines established by
the Trust's Board of Trustees. Eligible securities generally include (i) U.S.
government obligations, (ii) securities that are rated (at the time of purchase)
by nationally recognized statistical rating organizations ("Rating Agencies") in
the two highest rating categories for such securities, and (iii) certain
securities that are not so rated but are of comparable quality to rated
securities as determined by the Adviser. A description of ratings is also
contained in the Statement of Additional Information.

         The Fund's assets have remaining maturities of 397 calendar days or
less (except for certain variable and floating rate instruments and securities
underlying certain repurchase agreements) as defined by the SEC, and the Fund's
dollar-weighted average portfolio maturity may not exceed 90 days.



                                      -18-
<PAGE>   241

         RATINGS CRITERIA
         ----------------

                  The Balanced Allocation and Michigan Municipal Bonds Fund may
invest in investment grade debt securities which are rated at the time of
purchase within the four highest ratings groups assigned by Moody's (Aaa, Aa, A
and Baa), S&P (AAA, AA, A and BBB), Fitch (AAA, AA, A and BBB) or Duff (AAA, AA,
A and BBB), or, if unrated, which are determined by the Adviser to be of
comparable quality pursuant to guidelines approved by the Trust's Board of
Trustees. Debt securities rated in the lowest investment grade debt category
(Baa by Moody's or BBB by S&P, Fitch or Duff) have speculative characteristics;
changes in economic conditions or other circumstances are more likely to lead to
a weakened capacity to make principal and interest payments than is the case
with higher grade securities.

                  In the event that, subsequent to its purchase by a Fund, a
rated security ceases to be rated or its rating is reduced below investment
grade, the Adviser will consider whether the Fund should continue to hold the
security. The Adviser expects, however, to sell promptly any securities that are
non-investment grade as a result of such events that exceed 5% of a Fund's net
assets where the Adviser has determined that such sale is in the best interest
of the particular Fund.

SHAREHOLDER VOTE
- ----------------

                  As used in this prospectus, a "vote of the holders of a
majority of the outstanding shares" of the Trust or a particular investment fund
means, with respect to the approval of an investment advisory agreement, a
distribution plan or a change in a fundamental investment policy, the
affirmative vote of the lesser of (a) 50% or more of the outstanding shares of
the Trust or such fund or (b) 67% or more of the shares of the Trust or such
fund present at a meeting if more than 50% of the outstanding shares of the
Trust or such fund are represented at the meeting in person or by proxy.

ADDITIONAL INFORMATION ABOUT PORTFOLIO INSTRUMENTS
- --------------------------------------------------

ELIGIBLE SECURITIES
- -------------------

                  The Money Market Funds may purchase "eligible securities" that
present minimal credit risks as determined by the Adviser pursuant to guidelines
established by the Trust's Board of Trustees. Eligible securities generally
include: (1) securities that are rated by two or more Rating Agencies (or the
only Rating Agency which has issued a rating) in one of the two highest rating
categories for short term debt securities; (2) securities that have no short
term rating, if the issuer has other outstanding short term obligations that are
comparable in priority and security as determined by the Adviser ("Comparable
Obligations") and that have been rated in accordance with (1) above; (3)
securities that have no short term rating, but are determined to be of
comparable quality to a security satisfying (1) or (2) above, and the issuer
does not have Comparable Obligations rated by a Rating Agency; and (4)
securities with credit supports that meet specified rating criteria similar to
the foregoing and other criteria in accordance with applicable Securities



                                      -19-
<PAGE>   242

and Exchange Commission ("SEC") regulations. Securities issued by a money market
fund and securities issued by the U.S. Government may constitute eligible
securities if permitted under applicable SEC regulations and Trust procedures.
The Board of Trustees will approve or ratify any purchases by the Money Market
Funds of securities that are rated by only one Rating Agency or that qualify
under (3) above as long as required by applicable regulations or Trust
procedures.

VARIABLE AND FLOATING RATE INSTRUMENTS
- --------------------------------------

                  Each Fund (other than the Equity Index, Treasury Money Market
and Treasury Plus Money Market Funds) may purchase variable and floating rate
obligations (including variable amount master demand notes) which are unsecured
instruments that permit the indebtedness thereunder to vary and provide for
periodic adjustments in the interest rate. Because variable and floating rate
obligations are direct lending arrangements between the Fund and the issuer,
they are not normally traded although certain variable and floating rate
obligations, such as Student Loan Marketing Association variable rate
obligations, may have a more active secondary market because they are issued or
guaranteed by the U.S. Government or its agencies or instrumentalities. Even
though there may be no active secondary market in such instruments, a Fund may
demand payment of principal and accrued interest at a time specified in the
instrument or may resell them to a third party. Such obligations may be backed
by bank letters of credit or guarantees issued by banks, other financial
institutions or the U.S. Government, its agencies or instrumentalities. The
quality of any letter of credit or guarantee will be rated high quality or, if
unrated, will be determined to be of comparable quality by the Adviser. In the
event an issuer of a variable or floating rate obligation defaulted on its
payment obligation, a Fund might be unable to dispose of the instrument because
of the absence of a secondary market and could, for this or other reasons,
suffer a loss to the extent of the default.

                  The Funds may purchase variable rate and floating rate
obligations as described in the Prospectus. The Adviser will consider the
earning power, cash flows and other liquidity ratios of the issuers and
guarantors of such notes and will continuously monitor their financial status to
meet payment on demand. In determining average weighted portfolio maturity, a
variable or floating rate instrument issued or guaranteed by the U.S. government
or an agency or instrumentality thereof will be deemed to have a maturity equal
to the period remaining until the obligation's next interest rate adjustment.
Other variable and floating rate obligations will be deemed to have a maturity
equal to the longer or shorter of the periods remaining to the next interest
rate adjustment or the demand notice period in accordance with applicable
regulations or Trust procedures.

                  Variable and floating rate obligations held by a Fund may have
maturities of more than 397 days, provided: (a) (i) the Fund is entitled to
payment of principal and accrued interest upon not more than 30 days' notice or
at specified intervals not exceeding one year (upon not more than 30 days'
notice) and (ii) the rate of interest on such instrument is adjusted
automatically at periodic intervals which normally will not exceed 31 days, but
may extend up to one year, or (b) if the obligation is an asset-backed security,
and if permitted under Trust procedures and applicable regulations, the security
has a feature permitting the holder unconditionally to receive principal and
interest within 13 months of making demand.

GUARANTEED INVESTMENT CONTRACTS
- -------------------------------

                  The International Equity, Small Cap Value, Small Cap Growth,
Equity Growth, Tax Managed Equity, Core Equity, Equity Income, Balanced
Allocation, Total Return Advantage, Intermediate Bond and Enhanced Income Funds
and the Money Market Funds may make limited investments in "GICs" issued by U.S.
insurance companies. When investing in "GICs" a Fund makes cash contributions to
a deposit fund or an insurance company's general account. The insurance company
then credits to that Fund monthly a guaranteed minimum interest which is based
on an index. The GICs provide that this guaranteed interest will not be less
than a certain minimum rate. The insurance company may assess periodic charges
against a GIC for expense and service costs allocable to it, and the charges
will be deducted from the value of the deposit fund. A Fund will purchase a GIC
only when its Adviser or Sub-Adviser has determined, under guidelines
established by the Board of Trustees, that the GIC presents minimal credit risks
to the Fund and is of comparable quality to instruments that are rated high
quality by one or more rating agencies. For the Money Market Fund, the Fund's
investments in GICs will not exceed 10% of the Fund's net assets. In addition,
because each Fund may not receive the principal amount of a GIC from the
insurance company on seven days' notice or less, the GIC is considered an
illiquid investment, and, together with other instruments in the Fund which are
not readily marketable, will not exceed 15%, 10% in the case of the Money Market
Fund of the Fund's net assets.

                  The term of a GIC will be one year or less. In determining
average weighted portfolio maturity, a GIC will be deemed to have a maturity
equal to the period of time remaining until the next readjustment of the
guaranteed interest rate.

BANK OBLIGATIONS AND COMMERCIAL PAPER
- -------------------------------------

                  The Ohio Municipal Money Market, Pennsylvania Tax Exempt Money
Market, Money Market, Mid Cap Growth and Michigan Municipal Bond Funds may
invest in bank obligations. Bank obligations include bankers' acceptances
generally having a maturity of six months or less and negotiable certificates of
deposit. Bank obligations also include U.S. dollar denominated bankers'
acceptances and certificates of deposit. Investment in bank obligations is
limited to the obligations of financial institutions having more than $1 billion
in total assets at the time of purchase. For purposes of the Money Market Fund's
investment policy with respect to bank obligations, the assets of a bank or
savings institution will be deemed to include the assets of its domestic and
foreign branches.

                  Investments by the Ohio Municipal, Pennsylvania Tax Exempt
Fund, Mid Cap Growth and Michigan Tax Exempt Bond Funds in commercial paper and
other short term promissory notes issued by corporations, municipalities and
other entities (including variable and floating rate instruments) must be rated
at the time of purchase "A-2" or better by S&P, "Prime-2" or better by Moody's,
"F-2" or better by Fitch, "Duff 2" or better by Duff, or if not rated,
determined by the adviser to be of comparable quality pursuant to guidelines
approved by the Trust's Board of Trustees. Investments may also include
corporate notes. In addition, the Mid Cap Growth Fund may invest in Canadian
commercial paper, which is U.S. dollar denominated



                                      -21-
<PAGE>   244

commercial paper issued by a Canadian corporation or a Canadian counterpart of a
U.S. corporation.

REPURCHASE AGREEMENTS
- ---------------------

                  Securities held by the International Equity, Small Cap Growth,
Tax Managed Equity, Core Equity, Equity Index, Balanced Allocation, Total Return
Advantage, Bond, Intermediate Bond, GNMA, Enhanced Income, Ohio Municipal Money
Market, Pennsylvania Tax-Exempt Money Market, Money Market, Government Money
Market, Treasury Plus Money Market, Mid Cap Growth, U.S. Government Income and
Michigan Municipal Bond Funds may be subject to repurchase agreements. Under the
terms of a repurchase agreement, a Fund purchases securities from financial
institutions such as banks and broker-dealers which the Fund's Adviser or Sub
Adviser deems creditworthy under guidelines approved by the Board of Trustees,
subject to the seller's agreement to repurchase such securities at a mutually
agreed-upon date and price. The repurchase price generally equals the price paid
by the Fund plus interest negotiated on the basis of current short term rates,
which may be more or less than the rate on the underlying portfolio securities.

                  The seller under a repurchase agreement will be required to
maintain the value of collateral held pursuant to the agreement at not less than
the repurchase price (including accrued interest). If the seller were to default
on its repurchase obligation or become insolvent, the Fund holding such
obligation would suffer a loss to the extent that the proceeds from a sale of
the underlying portfolio securities were less than the repurchase price under
the agreement, or to the extent that the disposition of such securities by the
Fund were delayed pending court action. Although there is no controlling legal
precedent confirming that a Fund would be entitled, as against a claim by such
seller or its receiver or trustee in bankruptcy, to retain the underlying
securities, the Board of Trustees of the Trust believes that, under the regular
procedures normally in effect for custody of a Fund's securities subject to
repurchase agreements and under federal laws, a court of competent jurisdiction
would rule in favor of the Trust if presented with the question. Securities
subject to repurchase agreements will be held by the Trust's custodian or
another qualified custodian or in the Federal Reserve/Treasury book-entry
system. Repurchase agreements are considered to be loans by a Fund under the
1940 Act.

                  With respect to the Ohio Municipal Money Market, Pennsylvania
Tax Exempt Money Market, Tax Exempt Money Market, Money Market, Government Money
Market and Treasury Plus Money Market Funds, although the securities subject to
repurchase agreements may bear maturities exceeding 397 days, the Funds
presently intend to enter only into repurchase agreements which terminate within
seven days after notice by the Funds. If a Fund were to enter into repurchase
agreements which provide for a notice period greater than seven days in the
future, the Fund would do so only if such investment, together with other
illiquid securities, did not exceed 10% of the Fund's net assets.



                                      -22-
<PAGE>   245

REVERSE REPURCHASE AGREEMENTS
- -----------------------------

                  The International Equity, Small Cap Value, Small Cap Growth,
Equity Growth, Tax Managed Equity, Core Equity, Equity Index, Equity Income,
Balanced Allocation, Total Return Advantage, Ohio Municipal Money Market,
Pennsylvania Tax Exempt Money Market, Money Market, Government Money Market and
Mid Cap Growth Funds may enter into reverse repurchase agreements in accordance
with its investment restrictions. Pursuant to such agreements, a Fund would sell
portfolio securities to financial institutions such as banks and broker-dealers,
and agree to repurchase them at a mutually agreed-upon date and price. A Fund
intends to enter into reverse repurchase agreements only to avoid otherwise
selling securities during unfavorable market conditions to meet redemptions. At
the time a Fund enters into a reverse repurchase agreement, it will place in a
segregated custodial account assets such as U.S. Government securities or other
liquid, high grade debt securities consistent with the Fund's investment
restrictions having a value at least equal to the repurchase price (including
accrued interest), and will subsequently monitor the account to ensure that such
equivalent value is maintained. Whenever the Ohio Municipal Money Market,
Pennsylvania Tax-Exempt Money Market, Money Market and Government Money Market
Funds enter into a reverse repurchase agreement as described in the Prospectus,
it will place in a segregated custodial account liquid assets at least equal to
the repurchase price marked to market daily (including accrued interest) and
will subsequently monitor the account to ensure such equivalent value is
maintained. Reverse repurchase agreements involve the risk that the market value
of the securities sold by a Fund may decline below the price at which it is
obligated to repurchase the securities. Reverse repurchase agreements are
considered to be borrowings by the Fund under the 1940 Act.

LENDING OF PORTFOLIO SECURITIES
- -------------------------------

                  The International Equity, Small Cap Value, Small Cap Growth,
Equity Growth, Tax Managed Equity, Core Equity, Equity Index, Equity Income,
Balanced Allocation, Total Return Advantage, Bond, Intermediate Bond, GNMA,
Enhanced Income, Money Market, Government Money Market, Treasury Plus Money
Market, Mid Cap Growth and U.S. Government Income Funds may lend securities to
broker-dealers, banks or other institutional borrowers pursuant to agreements
requiring that the loans be continuously secured by cash, securities of the U.S.
government or its agencies, or any combination of cash and such securities, as
collateral equal to 100% of the market value at all times of the securities
lent. Such loans will not be made if, as a result, the aggregate amount of all
outstanding securities loans for a Fund exceed one-third of the value of its
total assets taken at fair market value. Collateral must be valued daily by the
Fund's Adviser or Sub-adviser and the borrower will be required to provide
additional collateral should the market value of the loaned securities increase.
During the time portfolio securities are on loan, the borrower pays the Fund
involved any dividends or interest paid on such securities. Loans are subject to
termination by the Fund or the borrower at any time. While a Fund does not have
the right to vote securities on loan, it intends to terminate the loan and
regain the right to vote if this is considered important with respect to the
investment. A Fund will only enter into loan arrangements with broker-dealers,
banks or other institutions which its Adviser or Sub-adviser has determined are
creditworthy under guidelines established by the Trust's Board of Trustees.



                                      -23-
<PAGE>   246

                  A Fund will continue to receive interest on the securities
lent while simultaneously earning interest on the investment of the cash
collateral in U.S. government securities. However, a Fund will normally pay
lending fees to such broker-dealers and related expenses from the interest
earned on invested collateral. There may be risks of delay in receiving
additional collateral or risks of delay in recovery of the securities or even
loss of rights in the collateral should the borrower of the securities fail
financially. However, loans are made only to borrowers deemed by the Adviser to
be of good standing and when, in the judgment of the adviser, the consideration
which can be earned currently from such securities loans justifies the attendant
risk. Any loan may be terminated by either party upon reasonable notice to the
other party.

ILLIQUID SECURITIES
- -------------------

                  The International Equity, Small Cap Value, Small Cap Growth,
Equity Growth, Tax Managed Equity, Core Equity, Equity Index, Equity Income,
Total Return Advantage, Bond, Intermediate Bond, GNMA, Enhanced Income, Ohio Tax
Exempt Bond, Pennsylvania Municipal Bond, National Tax Exempt Bond, Mid Cap
Growth, U.S. Government Income and Michigan Municipal Bond Funds will not invest
more than 15% of their respective net assets in securities that are illiquid.
The Money Market Funds will not knowingly invest more than 10% of the value of
their respective net assets in securities that are illiquid. Illiquid securities
would generally include repurchase agreements and GICs with notice/termination
dates in excess of seven days and certain securities which are subject to
trading restrictions because they are not registered under the Securities Act of
1933, as amended (the "1933 Act").

                  Each Fund may purchase securities which are not registered
under the 1933 Act but which can be sold to "qualified institutional buyers" in
accordance with Rule 144A under the 1933 Act. Any such security will not be
considered illiquid so long as it is determined by the Board of Trustees or the
Fund's Adviser or Sub-adviser, acting under guidelines approved and monitored by
the Board, that an adequate trading market exists for that security. This
investment practice could have the effect of increasing the level of illiquidity
in a Fund during any period that qualified institutional buyers become
uninterested in purchasing these restricted securities.

TAXABLE MONEY MARKET INSTRUMENTS
- --------------------------------

                  The Ohio Tax Exempt Bond, Pennsylvania Municipal, National Tax
Exempt Bond and Michigan Municipal Bond Funds may invest, from time to time, a
portion of its assets for temporary defensive or liquidity purposes in
short-term money market instruments, the income from which is subject to federal
income tax ("Taxable Money Market Instruments"). Taxable Money Market
Instruments may include: obligations of the U.S. government and its agencies and
instrumentalities; debt securities (including commercial paper) of issuers
having, at the time of purchase, a quality rating within the highest rating
category of S&P, Fitch, Duff, or Moody's; certificates of deposit; bankers'
acceptances; and repurchase agreements with respect to such obligations.

FOREIGN SECURITIES AND CURRENCIES
- ---------------------------------

                  The International Equity, Small Cap Value, Small Cap Growth,
Equity Growth, Tax Managed Equity, Core Equity, Equity Income, Balanced
Allocation and Mid Cap Growth Funds may invest up to 20% (100% in the case of
the International Equity Fund) of its total assets at the time of purchase in
securities issued by foreign entities and ADRs, EDRs and GDRs (defined below).

                  The Total Return Advantage, Intermediate Bond, Enhanced Income
and U.S. Government Income Funds may also invest in securities issued by foreign
issuers either directly or indirectly through investments in American, European
or Global Depository Receipts (see "American, European and Global Depository
Receipts" below). Such securities may or may not be listed on foreign or
domestic stock exchanges.

                  Investments in foreign securities involve certain inherent
risks, such as political or economic instability of the issuer or the country of
issue, the difficulty of predicting international trade patterns, changes in
exchange rates of foreign currencies and the possibility of adverse changes in
investment or exchange control regulations. There may be less publicly available
information about a foreign company than about a domestic company. Foreign
companies generally are not subject to uniform accounting, auditing and
financial reporting standards comparable to those applicable to domestic
companies. Further, foreign stock markets are generally not as developed or
efficient as those in the U.S., and in most foreign markets, volume and
liquidity are less than in the U.S. Fixed commissions on foreign stock exchanges
are generally higher than the negotiated commissions on U.S. exchanges, and
there is generally less government supervision and regulation of foreign stock
exchanges, brokers and companies than in the U.S.

                  With respect to certain foreign countries, there is a
possibility of expropriation or confiscatory taxation, limitations on the
removal of funds or other assets, or diplomatic developments that could affect
investment within those countries. Because of these and other factors,
securities of foreign companies acquired by the Fund may be subject to greater
fluctuation in price than securities of domestic companies.

                  Since the Funds will invest substantially in securities
denominated in or quoted in currencies other than the U.S. dollar, changes in
currency exchange rates (as well as changes in market values) will affect the
value in U.S. dollars of securities held by the Fund. Foreign exchange rates are
influenced by trade and investment flows, policy decisions of governments, and
investor sentiment about these and other issues. In addition, costs are incurred
in connection with conversions between various currencies.

                  The conversion of the eleven member states of the European
Union to a common currency, the "euro," is scheduled to occur on January 1,
1999. As a result of the conversion, securities issued by the member states will
be subject to certain risks, including competitive implications of increased
price transparency of European Union markets (including labor markets) resulting
from adoption of a common currency and issuers' plans for pricing their own


                                      -25-
<PAGE>   248

products and services in euro; an issuer's ability to make any required
information technology updates on a timely basis, and costs associated with the
conversion (including costs of dual currency operations through January 1,
2002); currency exchange rate risk and derivatives exposure (including the
disappearance of price sources, such as certain interest rate indices) and
continuity of material contracts and potential tax consequences. Other risks
include whether the payment and operational systems of banks and other financial
institutions will be ready by the scheduled launch date; the creation of
suitable clearing and settlement payment systems for the new currency; the legal
treatment of certain outstanding financial contracts after January 1, 1999 that
refer to existing currencies rather than the euro; the establishment and
maintenance of exchange rates for currencies being converted into the euro; the
fluctuation of the euro relative to non-euro currencies during the transition
period from January 1, 1999 to December 31, 2000 and beyond; whether the
interest rate, tax and labor regimes of participating European countries will
converge over time; and whether the conversion of the currencies of other EU
countries such as the United Kingdom, Denmark and Greece into the euro and the
possible admission of other non-EU countries such as Poland, Latvia and
Lithuania as members of the EU may have an impact on the euro.

                  These or other factors, including political and economic
risks, could cause market disruptions before or after the introduction of the
euro, and could adversely affect the value of securities and foreign currencies
held by the Funds. Commissions on transactions in foreign securities may be
higher than those for similar transactions on domestic stock markets. In
addition, clearance and settlement procedures may be different in foreign
countries and, in certain markets, such procedures have been unable to keep pace
with the volume of securities transactions, thus making it difficult to conduct
such transactions.

                  The expense ratio of a Fund can be expected to be higher than
that of funds investing in domestic securities. The costs of investing abroad
are generally higher for several reasons, including the cost of investment
research, increased costs of custody for foreign securities, higher commissions
paid for comparable transactions involving foreign securities, and costs arising
from delays in settlements of transactions involving foreign securities.

                  Interest and dividends payable on the Fund's foreign portfolio
securities may be subject to foreign withholding taxes. To the extent such taxes
are not offset by tax credits or deductions allowed to investors under U.S.
federal income tax provisions, they may reduce the return to the Fund's
shareholders.

                  The Funds may invest in ADRs. Some of the Funds may also
invest in SPDRs, EDRs, GDRs and other similar global instruments. The Mid Cap
Growth Fund may also invest in MidCap SPDRs. ADRs are receipts issued in
registered form by a U.S. bank or trust company evidencing ownership of
underlying securities issued by a foreign issuer. ADRs may be listed on a
national securities exchange or may be traded in the over-the-counter markets.
ADR prices are denominated in U.S. dollars although the underlying securities
may be denominated in a foreign currency. SPDRs are receipts designed to
replicate the performance of the S&P 500. MidCap SPDRs represent ownership in
the MidCap SPDR Trust, a unit investment trust which holds a portfolio of common
stocks that closely tracks the price performance and dividend yield of the S&P


                                      -26-
<PAGE>   249

MidCap 400 Index. EDRs, which are sometimes referred to as Continental
Depository Receipts, are receipts issued in Europe typically by non-U.S. banks
or trust companies and foreign branches of U.S. banks that evidence ownership of
foreign or U.S. securities. EDRs are designed for use in European exchange and
over-the-counter markets. GDRs are receipts structured similarly to EDRs and are
marketed globally. GDRs are designed for trading in non-U.S. securities markets.
Investments in ADRs, EDRs and GDRs involve risks similar to those accompanying
direct investments in foreign securities, but those that are traded in the
over-the-counter market which do not have an active or substantial secondary
market will be considered illiquid and, therefore, will be subject to a Fund's
limitation with respect to illiquid securities.

                  The principal difference between sponsored and unsponsored
ADR, EDR and GDR programs is that unsponsored ones are organized independently
and without the cooperation of the issuer of the underlying securities.
Consequently, available information concerning the issuer may not be as current
as for sponsored ADRs, EDRs and GDRs, and the prices of unsponsored ADRs, EDRs
and GDRs may be more volatile.

FOREIGN GOVERNMENT OBLIGATIONS
- ------------------------------

                  The International Equity, Balanced Allocation, Mid Cap Growth
and U.S. Government Income Funds may purchase debt obligations issued or
guaranteed by governments (including states, provinces or municipalities) of
countries other than the United States, or by their agencies, authorities or
instrumentalities. The percentage of assets invested in securities of a
particular country or denominated in a particular currency will vary in
accordance with the Adviser's or Sub-Adviser's assessment of gross domestic
product in relation to aggregate debt, current account surplus or deficit, the
trend of the current account, reserves available to defend the currency, and the
monetary and fiscal policies of the government.

FOREIGN CURRENCY TRANSACTIONS
- -----------------------------

                  In order to protect against a possible loss on investments
resulting from a decline or appreciation in the value of a particular foreign
currency against the U.S. dollar or another foreign currency or for other
reasons, the International Equity, Equity Income, Balanced Allocation, Total
Return Advantage, Enhanced Income, Mid Cap Growth and U.S. Government Income
Funds are authorized to enter into forward currency exchange contracts. These
contracts involve an obligation to purchase or sell a specified currency at a
future date at a price set at the time of the contract. Forward currency
contracts do not eliminate fluctuations in the values of portfolio securities
but rather allow the Funds to establish a rate of exchange for a future point in
time.

                  When entering into a contract for the purchase or sale of a
security, these Funds may enter into a forward foreign currency exchange
contract for the amount of the purchase or sale price to protect against
variations, between the date the security is purchased or sold and the date on
which payment is made or received, in the value of the foreign currency relative
to the U.S. dollar or other foreign currency.



                                      -27-
<PAGE>   250

                  When the Adviser or Sub-Adviser anticipates that a particular
foreign currency may decline substantially relative to the U.S. dollar or other
leading currencies, in order to reduce risk, the Fund may enter into a forward
contract to sell, for a fixed amount, the amount of foreign currency
approximating the value of some or all of the Fund's securities denominated in
such foreign currency. Similarly, when the obligations held by the Fund create a
short position in a foreign currency, the Fund may enter into a forward contract
to buy, for a fixed amount, an amount of foreign currency approximating the
short position. With respect to any forward foreign currency contract, it will
not generally be possible to match precisely the amount covered by that contract
and the value of the securities involved due to the changes in the values of
such securities resulting from market movements between the date the forward
contract is entered into and the date it matures. In addition, while forward
contracts may offer protection from losses resulting from declines or
appreciation in the value of a particular foreign currency, they also limit
potential gains which might result from changes in the value of such currency. A
Fund will also incur costs in connection with forward foreign currency exchange
contracts and conversions of foreign currencies and U.S. dollars.

                  A separate account consisting of liquid assets, such as cash,
U.S. Government securities or other liquid high grade debt obligations equal to
the amount of the International Equity, Equity Income, Balanced Allocation,
Total Return Advantage and Enhanced Income Funds' assets that could be required
to consummate forward contracts will be established with the Trust's custodian
except to the extent the contracts are otherwise "covered." For the purpose of
determining the adequacy of the securities in the account, the deposited
securities will be valued at market or fair value. If the market or fair value
of such securities declines, additional cash or liquid securities will be placed
in the account daily so that the value of the account will equal the amount of
such commitments by the Funds. A forward contract to sell a foreign currency is
"covered" if the Fund owns the currency (or securities denominated in the
currency) underlying the contract, or holds a forward contract (or call option)
permitting the Fund to buy the same currency at a price no higher than the
Fund's price to sell the currency. A forward contract to buy a foreign currency
is "covered" if the Fund holds a forward contract (or call option) permitting
the Funds to sell the same currency at a price as high as or higher than the
Fund's price to buy the currency.

EXCHANGE RATE-RELATED SECURITIES
- --------------------------------

                  The International Equity, Equity Income, Balanced Allocation,
Total Return Advantage and Enhanced Income Funds may invest in debt securities
for which the principal due at maturity, while paid in U.S. dollars, is
determined by reference to the exchange rate between the U.S. dollar and the
currency of one or more foreign countries ("Exchange Rate-Related Securities").
The interest payable on these securities is also denominated in U.S. dollars and
is not subject to foreign currency risk and, in most cases, is paid at rates
higher than most other similarly rated securities in recognition of the risks
associated with these securities. There is the possibility of significant
changes in rates of exchange between the U.S. dollar and any foreign currency to
which an Exchange Rate-Related Security is linked. In addition, there is no
assurance that sufficient trading interest to create a liquid secondary market
will exist for a particular Exchange Rate-Related Security due to conditions in
the debt and foreign currency markets. Illiquidity in the forward foreign
exchange market and the high volatility of the foreign


                                      -28-
<PAGE>   251

exchange market may, from time to time, combine to make it difficult to sell an
Exchange Rate-Related Security prior to maturity without incurring a significant
price loss.

CONVERTIBLE SECURITIES
- ----------------------

                  The Equity Growth, Balanced Allocation and Mid Cap Growth
Funds may invest in convertible securities entitling the holder to receive
interest paid or accrued on debt or the dividend paid on preferred stock until
the securities mature or are redeemed, converted or exchanged. Prior to
conversion, convertible securities have characteristics similar to ordinary debt
securities in that they normally provide a stable stream of income with
generally higher yields than those of common stock of the same or similar
issuers. Convertible securities rank senior to common stock in a corporation's
capital structure and therefore generally entail less risk than the
corporation's common stock. The value of the convertibility feature depends in
large measure upon the degree to which the convertible security sells above its
value as a fixed income security.

                  In selecting convertible securities, the Adviser or
Sub-Adviser will consider, among other factors, the creditworthiness of the
issuers of the securities; the interest or dividend income generated by the
securities; the potential for capital appreciation of the securities and the
underlying common stocks; the prices of the securities relative to other
comparable securities and to the underlying common stocks; whether the
securities are entitled to the benefits of sinking funds or other protective
conditions; diversification of the Fund's portfolio as to issuers; and the
ratings of the securities. Since credit rating agencies may fail to timely
change the credit ratings of securities to reflect subsequent events, the
Adviser or Sub-Adviser will consider whether such issuers will have sufficient
cash flow and profits to meet required principal and interest payments. A Fund
may retain a portfolio security whose rating has been changed if the Adviser
deems that retention of such security is warranted.

CORPORATE DEBT OBLIGATIONS
- --------------------------

                  The Balanced Allocation, Total Return Advantage, Bond,
Intermediate Bond, GNMA, Enhanced Income, Mid Cap Growth, U.S. Government
Income, Michigan Municipal Bond and the Money Market Funds may invest in
corporate debt obligations. In addition to obligations of corporations,
corporate debt obligations include securities issued by banks and other
financial institutions. Corporate debt obligations are subject to the risk of an
issuer's inability to meet principal and interest payments on the obligations.

OTHER DEBT SECURITIES
- ---------------------

                  The Balanced Allocation, Total Return Advantage, Intermediate
Bond and Enhanced Income Funds may also invest in debt securities which may
include: equipment lease and trust certificates; collateralized mortgage
obligations; state, municipal and private activity bonds; obligations issued or
guaranteed by the U.S. government, its agencies or instrumentalities; securities
of supranational organizations such as the World Bank; participation
certificates in pools of mortgages, including mortgages issued or guaranteed by
the U.S. government, its agencies or instrumentalities; asset-backed securities
such as mortgage backed securities,



                                      -29-
<PAGE>   252

Certificates of Automobile Receivables ("CARS") and Certificates of Amortizing
Revolving Debts ("CARDS"); private placements; and income participation loans.
Some of the securities in which the Fund invests may have warrants or options
attached.

                  The Balanced Allocation, Total Return Advantage, Intermediate
Bond and Enhanced Income Funds' appreciation may result from an improvement in
the credit standing of an issuer whose securities are held or a general decline
in the level of interest rates or a combination of both. An increase in the
level of interest rates generally reduces the value of the fixed rate debt
instruments held by the Fund; conversely, a decline in the level of interest
rates generally increases the value of such investments. An increase in the
level of interest rates may temporarily reduce the value of the floating rate
debt instruments held by the Fund; conversely, a decline in the level of
interest rates may temporarily increase the value of those investments.

                  The Balanced Allocation, Total Return Advantage, Intermediate
Bond, and Enhanced Income Funds invest only in investment grade debt securities
which are rated at the time of purchase within the four highest ratings groups
assigned by Moody's (Aaa, Aa, A and Baa), S&P (AAA, AA, A and BBB), Fitch (AAA,
AA, A and BBB), or Duff (AAA, AA, A and BBB) or, if unrated, which are
determined by the Fund's adviser to be of comparable quality pursuant to
guidelines approved by the Trust's Board of Trustees. Debt securities rated in
the lowest investment grade debt category (Baa by Moody's or BBB by S&P, Fitch
or Duff or IBCA) may have speculative characteristics; changes in economic
conditions or other circumstances are more likely to lead to a weakened capacity
to make principal and interest payments than is the case with higher grade
securities.

                  In the event that subsequent to its purchase by the Fund, a
rated security ceases to be rated or its rating is reduced below investment
grade, the adviser will consider whether the Fund should continue to hold the
security. The adviser expects, however, to sell promptly any securities that are
non-investment grade as a result of such events that exceed 5% of the Fund's net
assets where the adviser has determined that such sale is in the best interest
of the Fund.

RISKS RELATED TO LOWER RATED SECURITIES WHICH MAY BE PURCHASED BY THE TOTAL
- ---------------------------------------------------------------------------
RETURN ADVANTAGE FUND
- ---------------------

                  While any investment carries some risk, certain risks
associated with lower rated securities (commonly referred to as "junk bonds")
are different than those for investment grade securities. The risk of loss
through default is greater because lower rated securities are usually unsecured
and are often subordinate to an issuer's other obligations. Additionally, the
issuers of these securities frequently have high debt levels and are thus more
sensitive to difficult economic conditions, individual corporate developments
and rising interest rates. Consequently, the market price of these securities
may be quite volatile and may result in wider fluctuations in the Total Return
Advantage Fund's net asset value per share.

                  In addition, an economic downturn or increase in interest
rates could have a negative impact on both the markets for lower rated
securities (resulting in a greater number of bond defaults) and the value of
lower rated securities held by the Total Return Advantage Fund.



                                      -30-
<PAGE>   253

Current laws, such as those requiring federally insured savings and loan
associations to remove investments in lower rated securities from their funds,
as well as other pending proposals, may also have a material adverse effect on
the market for lower rated securities.

                  The economy and interest rates may affect lower rated
securities differently than other securities. For example, the prices of lower
rated securities are more sensitive to adverse economic changes or individual
corporate developments than are the prices of higher rated investments. In
addition, during an economic downturn or period in which interest rates are
rising significantly, highly leveraged issuers may experience financial
difficulties, which, in turn, would adversely affect their ability to service
their principal and interest payment obligations, meet projected business goals
and obtain additional financing.

                  If an issuer of a security held by the Total Return Advantage
Fund defaults, the Fund may incur additional expenses to seek recovery. In
addition, periods of economic uncertainty would likely result in increased
volatility for the market prices of lower rated securities as well as the Fund's
net asset value. In general, both the prices and yields of lower rated
securities will fluctuate.

                  In certain circumstances it may be difficult to determine a
security's fair value due to a lack of reliable objective information. Such
instances occur where there is no established secondary market for the security
or the security is lightly traded. As a result, the Total Return Advantage
Fund's valuation of a security and the price it is actually able to obtain when
it sells the security could differ.

                  Adverse publicity and investor perceptions, whether or not
based on fundamental analysis, may decrease the value and liquidity of lower
rated securities held by the Total Return Advantage Fund, especially in a thinly
traded market. Illiquid or restricted securities held by the Fund may involve
special registration responsibilities, liabilities and costs, and could involve
other liquidity and valuation difficulties.

                  The ratings of Moody's, S&P, Fitch and Duff evaluate the
safety of a lower rated security's principal and interest payments, but do not
address market value risk. Because the ratings of the rating agencies may not
always reflect current conditions and events, in addition to using recognized
rating agencies and other sources, the Sub-adviser performs its own analysis of
the issuers of lower rated securities purchased by the Fund. Because of this,
the Fund's performance may depend more on its own credit analysis than is the
case for mutual funds investing in higher rated securities.

                  The Sub-adviser continuously monitors the issuers of lower
rated securities held by the Total Return Advantage Fund for their ability to
make required principal and interest payments, as well as in an effort to
control the liquidity of the Fund so that it can meet redemption requests.

WARRANTS
- --------

                  The International Equity, Small Cap Value, Small Cap Growth,
Equity Growth, Tax Managed Equity, Core Equity, Equity Income, Balanced
Allocation and Mid Cap Growth Funds may invest in warrants. Warrants enable the
owner to subscribe to and purchase a specified number of shares of the issuing
corporation at a specified price during a specified period of time. The prices
of warrants do not necessarily correlate with the prices of the underlying
securities. The purchase of warrants involves the risk that the purchaser could
lose the purchase value of the warrant if the right to subscribe to additional
shares is not exercised prior to the warrant's expiration. Also, the purchase of
warrants involves the risk that the effective price paid for the warrant added
to the subscription price of the related security may exceed the value of the
subscribed security's market price such as when there is no movement in the
level of the underlying security.

FUTURES AND RELATED OPTIONS
- ---------------------------

                  The International Equity, Small Cap Value, Small Cap Growth,
Equity Growth, Tax Managed Equity, Core Equity, Equity Index, Equity Income and
Mid Cap Growth Funds may invest in stock index futures contracts and options of
futures contracts in attempting to hedge against changes in the value of
securities that it holds or intends to purchase. The Balanced Allocation Fund
may invest in stock index, interest rate, bond index and foreign currency
futures contracts and options on these futures contracts. The Total Return
Advantage, Bond and Enhanced Income Funds may invest in interest rate and Bond
index futures contracts and options on futures contracts and the Bond and GNMA
Funds may invest in futures contracts on U.S. Treasury Obligations in order to
offset an expected decrease in the value of their respective portfolios that
might otherwise result from a market decline. The International Equity, Small
Cap Value, Small Cap Growth, Equity Growth, Tax Managed Equity, Equity Index and
Equity Income Funds may invest in stock index futures contracts in attempting to
hedge against changes in the value of securities that it holds or intends to
purchase or to maintain liquidity. The International Equity Fund may also invest
in foreign current futures contract and options in anticipation of changes in
currency exchange rates. The U.S. Government Income Fund may invest in futures
contracts on U.S. Treasury obligations. A Fund might sell a futures contract in
order to offset an expected decrease in the value of its portfolio that might
otherwise result from a market decline. Each of these Funds may invest in the
instruments described either to hedge the value of their respective portfolio
securities as a whole, or to protect against declines occurring prior to sales
of securities in the value of the securities to be sold. Conversely, a Fund may
purchase a futures contract in anticipation of purchases of securities. In
addition, each of these Funds may utilize futures contracts in anticipation of
changes in the composition of its holdings for hedging purposes or to maintain
liquidity.

                  Futures contracts obligate a Fund, at maturity, to take or
make delivery of certain securities or the cash value of an index or the cash
value of a stated amount of a foreign currency. When interest rates are rising,
futures contracts can offset a decline in value of the securities held



                                      -32-
<PAGE>   255

by a Fund. When rates are falling or prices of securities are rising, these
contracts can secure higher yields for securities a Fund intends to purchase.

                  Each of the International Equity, Small Cap Value, Small Cap
Growth, Equity Growth, Tax Managed Equity, Equity Index, Equity Income, Balanced
Allocation, Total Return Advantage, Bond, GNMA, Enhanced Income, Mid Cap Growth
and U.S. Government Income Funds intend to comply with the regulations of the
Commodity Futures Trading Commission (CFTC) exempting it from registration as a
"commodity pool operator." A Fund's commodities transactions must constitute
bona fide hedging or other permissible transactions pursuant to such
regulations. In addition, a Fund may not engage in such transactions if the sum
of the amount of initial margin deposits and premiums paid for unexpired
commodity options, other than for bona fide hedging transactions, would exceed
5% of the liquidation value of its assets, after taking into account unrealized
profits and unrealized losses on such contracts it has entered into; provided,
however, that in the case of an option that is in-the-money at the time of
purchase, the in-the-money amount may be excluded in calculating the percentage
limitation. In connection with a Fund's position in a futures contract or option
thereon, it will create a segregated account of liquid assets, such as cash,
U.S. government securities or other liquid high grade debt obligations, or will
otherwise cover its position in accordance with applicable requirements of the
SEC.

                  The International Equity, Small Cap Value, Small Cap Growth,
Equity Growth, Tax Managed Equity, Equity Index, Equity Income, Balanced
Allocation, Total Return Advantage, Enhanced Income, Mid Cap Growth and U.S.
Government Income Funds may purchase and sell call and put options on futures
contracts traded on an exchange or board of trade. When a Fund purchases an
option on a futures contract, it has the right to assume a position as a
purchaser or seller of a futures contract at a specified exercise price at any
time during the option period. When a Fund sells an option on a futures
contract, it becomes obligated to purchase or sell a futures contract if the
option is exercised. In anticipation of a market advance, a Fund may purchase
call options on futures contracts as a substitute for the purchase of futures
contracts to hedge against a possible increase in the price of securities which
the Fund intends to purchase. Similarly, if the value of a Fund's securities is
expected to decline, it might purchase put options or sell call options on
futures contracts rather than sell futures contracts.

                  The Funds may write covered call options, buy put options, buy
call options and sell or "write" secured put options on a national securities
exchange and issued by the Options Clearing Corporation for hedging purposes.
Such transactions may be effected on a principal basis with primary reporting
dealers in U.S. government securities in an amount not exceeding 5% of a Fund's
net assets. Such options may relate to particular securities, stock or bond
indices, financial instruments or foreign currencies. Purchasing options is a
specialized investment technique which entails a substantial risk of a complete
loss of the amounts paid as premiums to the writer of the option.

                  A call option for a particular security gives the purchaser of
the option the right to buy, and a writer the obligation to sell, the underlying
security at the stated exercise price at any



                                      -33-
<PAGE>   256

time prior to or only at the expiration of the option, regardless of the market
price of the security. The premium paid to the writer is the consideration for
undertaking the obligations under the option contract. A put option for a
particular security gives the purchaser the right to sell the underlying
security at the stated exercise price at any time prior to the expiration date
of the option, regardless of the market price of the security. In contrast to an
option on a particular security, an option on a securities index provides the
holder with the right to make or receive a cash settlement upon exercise of the
option.

                  Each Fund may purchase and sell put options on portfolio
securities at or about the same time that it purchases the underlying security
or at a later time. By buying a put, a Fund limits its risk of loss from a
decline in the market value of the security until the put expires. Any
appreciation in the value of and yield otherwise available from the underlying
security, however, will be partially offset by the amount of the premium paid
for the put option and any related transaction costs. Call options may be
purchased by a Fund in order to acquire the underlying security at a later date
at a price that avoids any additional cost that would result from an increase in
the market value of the security. A Fund may also purchase call options to
increase its return to investors at a time when the call is expected to increase
in value due to anticipated appreciation of the underlying security. Prior to
its expiration, a purchased put or call option may be sold in a closing sale
transaction (a sale by a Fund, prior to the exercise of an option that it has
purchased, of an option of the same series), and profit or loss from the sale
will depend on whether the amount received is more or less than the premium paid
for the option plus the related transaction costs.

                  In addition, each Fund may write covered call and secured put
options. A covered call option means that a Fund owns or has the right to
acquire the underlying security subject to call at all times during the option
period. A secured put option means that a Fund maintains in a segregated account
with its custodian cash or U.S. government securities in an amount not less than
the exercise price of the option at all times during the option period. Such
options will be listed on a national securities exchange and issued by the
Options Clearing Corporation and may be effected on a principal basis with
primary reporting dealers in the U.S.

                  The aggregate value of the securities subject to options
written by a Fund will not exceed 25% of the value of its net assets. In order
to close out an option position prior to maturity, a Fund may enter into a
"closing purchase transaction" by purchasing a call or put option (depending
upon the position being closed out) on the same security with the same exercise
price and expiration date as the option which it previously wrote.

                  Options trading is a highly specialized activity and carries
greater than ordinary investment risk. Purchasing options may result in the
complete loss of the amounts paid as premiums to the writer of the option. In
writing a covered call option, a Fund gives up the opportunity to profit from an
increase in the market price of the underlying security above the exercise price
(except to the extent the premium represents such a profit). Moreover, it will
not be able to sell the underlying security until the covered call option
expires or is exercised or a Fund closes out the option. In writing a secured
put option, a Fund assumes the risk that the market value of the security will
decline below the exercise price of the option. The use of



                                      -34-
<PAGE>   257

covered call and secured put options will not be a primary investment technique
of a Fund. For a detailed description of these investments and related risks,
see Appendix B attached to this Statement of Additional Information.

         Risk Factors Associated with Futures and Related Options

                  To the extent the Total Return Advantage, Bond, GNMA and
Enhanced Income Funds are engaging in a futures transaction as a hedging device,
due to the risk of an imperfect correlation between securities in their funds
that are the subject of a hedging transaction and the futures contract used as a
hedging device, it is possible that the hedge will not be fully effective in
that, for example, losses on the portfolio securities may be in excess of gains
on the futures contract or losses on the futures contract may be in excess of
gains on the portfolio securities that were the subject of the hedge. In futures
contracts based on indices, the risk of imperfect correlation increases as the
composition of the Funds varies from the composition of the index. In an effort
to compensate for the imperfect correlation of movements in the price of the
securities being hedged and movements in the price of futures contracts, the
Funds may buy or sell futures contracts in a greater or lesser dollar amount
than the dollar amount of the securities being hedged if the historical
volatility of the futures contract has been less or greater than that of the
securities. Such "over hedging" or "under hedging" may adversely affect a Fund's
net investment results if market movements are not as anticipated when the hedge
is established.

                  Successful use of futures by the Funds also are subject to the
Adviser's or Sub-adviser's ability to predict correctly movements in the
direction of securities prices, interest rates and other economic factors. For
example, if the Funds have hedged against the possibility of a decline in the
market adversely affecting the value of securities held in their funds and
prices increase instead, the Funds will lose part or all of the benefit of the
increased value of securities which they have hedged because they will have
offsetting losses in their futures positions. In addition, in such situations,
if a Fund has insufficient cash, it may have to sell securities to meet daily
variation margin requirements. Such sales of securities may, but will not
necessarily, be at increased prices which reflect the rising market. The Funds
may have to sell securities at a time when it may be disadvantageous to do so.

                  Although the Total Return Advantage, Bond, GNMA and Enhanced
Income Funds intend to enter into futures contracts and the Total Return
Advantage and Enhanced Income Funds into options transactions only if there is
an active market for such investments, no assurance can be given that a liquid
market will exist for any particular contract or transaction at any particular
time. See "Illiquid Securities." Many futures exchanges and boards of trade
limit the amount of fluctuation permitted in futures contract prices during a
single trading day. Once the daily limit has been reached in a particular
contract, no trades may be made that day at a price beyond that limit or trading
may be suspended for specified periods during the trading day. Futures contracts
prices could move to the limit for several consecutive trading days with little
or no trading, thereby preventing prompt liquidation of futures positions and
potentially subjecting the Funds to substantial losses. If it is not possible,
or a Fund determines not, to close a futures position in anticipation of adverse
price movements, it will be required to make daily cash



                                      -35-
<PAGE>   258

payments of variation margin. In such circumstances, an increase in the value of
the portion of the Fund being hedged, if any, may offset partially or completely
losses on the futures contract.

                  The primary risks associated with the use of futures contracts
and options are:

                  1. the imperfect correlation between the change in market
value of the securities held by a Fund and the price of the futures contract or
option;

                  2. possible lack of a liquid secondary market for a futures
contract and the resulting inability to close a futures contract when desired;


                  3. losses greater than the amount of the principal invested as
initial margin due to unanticipated market movements which are potentially
unlimited; and


                  4. the Adviser's or Sub-adviser's, in the case of the Total
Return Advantage Fund, ability to predict correctly the direction of securities
prices, interest rates and other economic factors.


MORTGAGE-BACKED SECURITIES
- --------------------------

                  The Balanced Allocation, Total Return Advantage, Bond,
Intermediate Bond, GNMA, Enhanced Income and U.S. Government Income Funds may
purchase securities that are secured or backed by mortgages and are issued by
entities such as Government National Mortgage Association (GNMA), Federal
National Mortgage Association (FNMA), Federal Home Loan Mortgage Corporation
(FHLMC), or private mortgage conduits.

                  Mortgage-backed securities represent an ownership interest in
a pool of mortgages, the interest and principal payments on which may be
guaranteed by an agency or instrumentality of the U.S. government, although not
necessarily by the U.S. government itself. Mortgage-backed securities include
CMOs and mortgage pass-through certificates.

                  Mortgage pass-through certificates, which represent interests
in pools of mortgage loans, provide the holder with a pro rata interest in the
underlying mortgages. One type of such certificate in which the Fund may invest
is a GNMA Certificate which is backed as to the timely payment of principal and
interest by the full faith and credit of the U.S. government. Another type is a
FNMA Certificate, the principal and interest of which are guaranteed only by
FNMA itself, not by the full faith and credit of the U.S. government. Another
type is a FHLMC Participation Certificate which is guaranteed by FHLMC as to
timely payment of principal and interest. However, like a FNMA security it is
not guaranteed by the full faith and credit of the U.S. government. Privately
issued mortgage backed securities will carry an investment grade rating at the
time of purchase by S&P or by Moody's or, if unrated, will be in the adviser's
opinion equivalent in credit quality to such rating. Mortgage-backed securities
issued by private



                                      -36-
<PAGE>   259

issuers, whether or not such obligations are subject to guarantees by the
private issuer, may entail greater risk than obligations directly or indirectly
guaranteed by the U.S. government.

                  The yield and average life characteristics of mortgage-backed
securities differ from traditional debt securities. A major difference is that
the principal amount of the obligations may be prepaid at any time because the
underlying assets (i.e., loans) generally may be prepaid at any time. As a
result, if a mortgage-backed security is purchased at a premium, a prepayment
rate that is faster than expected will reduce the expected yield to maturity and
average life, while a prepayment rate that is slower than expected will have the
opposite effect of increasing yield to maturity and average life. Conversely, if
a mortgage-backed security is purchased at a discount, faster than expected
prepayments will increase, while slower than expected prepayments will decrease,
the expected yield to maturity and average life. There can be no assurance that
the Trust's estimation of the duration of mortgage-backed securities it holds
will be accurate or that the duration of such instruments will always remain
within the maximum target duration. In calculating the average weighted maturity
of the Funds, the maturity of mortgage-backed securities will be based on
estimates of average life.

                  Prepayments on mortgage-backed securities generally increase
with falling interest rates and decrease with rising interest rates;
furthermore, prepayment rates are influenced by a variety of economic and social
factors. Like other fixed income securities, when interest rates rise, the value
of mortgage-backed securities generally will decline; however, when interest
rates decline, the value of mortgage-backed securities may not increase as much
as that of other similar duration fixed income securities, and, as noted above,
changes in market rates of interest may accelerate or retard prepayments and
thus affect maturities.

                  These characteristics may result in a higher level of price
volatility for these assets under certain market conditions. In addition, while
the market for Mortgage-backed securities is ordinarily quite liquid, in times
of financial stress the market for these securities can become restricted.

DOLLAR ROLLS
- ------------

                  The Balanced Allocation, U.S. Government Income and Michigan
Municipal Bond Funds may invest in reverse repurchase agreements in the form of
Dollar Rolls. Dollar Rolls are transactions in which securities are sold by the
Fund for delivery in the current month and the Fund simultaneously contracts to
repurchase substantially similar securities on a specified future date. Any
difference between the sale price and the purchase price is netted against the
interest income foregone on the securities sold to arrive at an implied
borrowing rate. Alternatively, the sale and purchase transactions can be
executed at the same price, with the Fund being paid a fee as consideration for
entering into the commitment to purchase. Dollar Rolls may be renewed prior to
cash settlement and initially may involve only a firm commitment agreement by
the Fund to buy a security. If the broker-dealer to which the Fund sells the
security becomes insolvent, the Fund's right to repurchase the security may be
restricted. Other risks involved in entering into Dollar Rolls include the risk
that the value of the security may change adversely over the term of the Dollar
Roll and that the security the Fund is required to repurchase



                                      -37-
<PAGE>   260

may be worth less than the security that the Fund originally held. At the time a
Fund enters into a Dollar Roll, it will place in a segregated custodial account
assets such as U.S. government securities or other liquid, high grade debt
securities consistent with the Fund's investment restrictions having a value
equal to the repurchase price (including accrued interest), and will
subsequently monitor the account to ensure that such equivalent value is
maintained.

SHORT SALES
- -----------

                  The Tax Managed Equity, Balanced Allocation, GNMA, Mid Cap
Growth, U.S. Government Income and Michigan Municipal Bond Funds may engage in
short sales of its securities. Selling securities short involves selling
securities the seller does not own (but has borrowed) in anticipation of a
decline in the market price of such securities. To deliver the securities to the
buyer, the seller must arrange through a broker to borrow the securities and, in
so doing, the seller becomes obligated to replace the securities borrowed at
their market price at the time of replacement. In a short sale, the proceeds the
seller receives from the sale are retained by a broker until the seller replaces
the borrowed securities. The seller may have to pay a premium to borrow the
securities and must pay any dividends or interest payable on the securities
until they are replaced.

ASSET-BACKED SECURITIES
- -----------------------

                  As described in the Prospectus, the Balanced Allocation, Total
Return Advantage and the Fixed Income Funds may purchase asset-backed
securities, which are securities backed by mortgages, installment contracts,
credit card receivables or other assets. Asset-backed securities represent
interests in "pools" of assets in which payments of both interest and principal
on the securities are made monthly, thus in effect "passing through" monthly
payments made by the individual borrowers on the assets that underlie the
securities, net of any fees paid to the issuer or guarantor of the securities.
The average life of asset-backed securities varies with the maturities of the
underlying instruments, and the average life of a mortgage-backed instrument, in
particular, is likely to be substantially less than the original maturity of the
mortgage pools underlying the securities as a result of mortgage prepayments.
For this and other reasons, an asset-backed security's stated maturity may be
shortened, and the security's total return may be difficult to predict
precisely. Asset-backed securities acquired by the Fund may include
collateralized mortgage obligations (CMOs) issued by private companies.

                  In general, the collateral supporting non-mortgage,
asset-backed securities is of shorter maturity than mortgage loans and is less
likely to experience substantial prepayments. Such securities may also be debt
instruments, which are also known as collateralized obligations and are
generally issued as the debt of a special purpose entity organized solely for
the purpose of owning such assets and issuing such debt. Asset-backed securities
are not issued or guaranteed by the U.S. government or its agencies or
instrumentalities.

                  Each Fund may invest in securities the timely payment of
principal and interest on which are guaranteed by the GNMA a wholly-owned U.S.
Government corporation within the Department of Housing and Urban Development.
The market value and interest yield of these



                                      -38-
<PAGE>   261

instruments can vary due to market interest rate fluctuations and early
prepayments of underlying mortgages. These securities represent ownership in a
pool of federally insured mortgage loans. GNMA certificates consist of
underlying mortgages with a maximum maturity of 30 years. However, due to
scheduled and unscheduled principal payments, GNMA certificates have a shorter
average maturity and, therefore, less principal volatility than a comparable
30-year bond. Since prepayment rates vary widely, it is not possible to predict
accurately the average maturity of a particular GNMA pool. GNMA securities
differ from conventional bonds in that principal is paid back to the certificate
holders over the life of the loan rather than at maturity. The scheduled monthly
interest and principal payments relating to mortgages in the pool are "passed
through" to investors. In addition, there may be unscheduled principal payments
representing prepayments on the underlying mortgages. Although GNMA certificates
may offer yields higher than those available from other types of U.S. Government
securities, GNMA certificates may be less effective than other types of
securities as a means of "locking in" attractive long-term rates because of the
prepayment feature. For instance, when interest rates decline, the value of a
GNMA certificate likely will not rise as much as comparable debt securities due
to the prepayment feature. In addition, these prepayments can cause the price of
a GNMA certificate originally purchased at a premium to decline in price to its
par value, which may result in a loss.

                  There are a number of important differences among the agencies
and instrumentalities of the U.S. Government that issue mortgage-related
securities and among the securities that they issue. Mortgage-related securities
guaranteed by the GNMA include GNMA Mortgage Pass-Through Certificates (also
known as Ginnie Maes) which are guaranteed as to the timely payment of principal
and interest by GNMA and such guarantee is backed by the full faith and credit
of the United States. GNMA is a wholly-owned U.S. Government corporation within
the Department of Housing and Urban Development. GNMA certificates also are
supported by the authority of GNMA to borrow funds from the U.S. Treasury to
make payments under its guarantee. Mortgage-backed securities issued by the FNMA
include FNMA Guaranteed Mortgage Pass-Through Certificates (also known as
"Fannie Maes") which are solely the obligations of the FNMA and are not backed
by or entitled to the full faith and credit of the United States, but are
supported by the right of the issuer to borrow from the Treasury. FNMA is a
government-sponsored organization owned entirely by private stockholders. Fannie
Maes are guaranteed as to timely payment of the principal and interest by FNMA.
Mortgage-related securities issued by the FHLMC include FHLMC Mortgage
Participation Certificates (also known as "Freddie Macs" or "Pcs"). FHLMC is a
corporate instrumentality of the United States, created pursuant to an Act of
Congress, which is owned entirely by Federal Home Loan Banks. Freddie Macs are
not guaranteed by the United States or by any Federal Home Loan Banks and do not
constitute a debt or obligation of the United States or of any Federal Home Loan
Bank. Freddie Macs entitle the holder to timely payment of interest, which is
guaranteed by the FHLMC. FHLMC guarantees either ultimate collection or timely
payment of all principal payments on the underlying mortgage loans. When FHLMC
does not guarantee timely payment of principal, FHLMC may remit the amount due
on account of its guarantee of ultimate payment of principal at any time after
default on an underlying mortgage, but in no event later than one year after it
becomes payable.



                                      -39-
<PAGE>   262

                  Non-mortgage asset-backed securities involve certain risks
that are not presented by mortgage-backed securities. Primarily, these
securities may not have the benefit of the same security interest in the
underlying collateral. Credit card receivables are generally unsecured and the
debtors are entitled to the protection of a number of state and federal consumer
credit laws, many of which have given debtors the right to set off certain
amounts owed on the credit cards, thereby reducing the balance due. Most issuers
of automobile receivables permit the servicers to retain possession of the
underlying obligations. If the servicer were to sell these obligations to
another party, there is a risk that the purchaser would acquire an interest
superior to that of the holders of the related automobile receivables. In
addition, because of the large number of vehicles involved in a typical issuance
and technical requirements under state laws, the trustee for the holders of the
automobile receivables may not have an effective security interest in all of the
obligations backing such receivables. Therefore, there is a possibility that
recoveries on repossessed collateral may not, in some cases, be able to support
payments on these securities.

INTEREST RATE AND TOTAL RETURN SWAPS
- ------------------------------------

                  The Balanced Allocation, Total Return Advantage, GNMA,
Enhanced Income and U.S. Government Income Funds may enter into interest rate
swaps for hedging purposes and not for speculation. The Balance Allocation Fund
may also use total return swaps for the same purposes. The Fund will typically
use interest rate or total return swaps to preserve a return on a particular
investment or portion of its portfolio or to shorten the effective duration of
its investments. Swaps involve the exchange by the Fund with another party of
their respective commitments to pay or receive interest or the total return of a
predefined "index," such as an exchange of fixed rate payments for floating rate
payments or an exchange of a floating rate payment for the total return on an
index.

                  The net amount of the excess, if any, of a Fund's obligations
over its entitlements with respect to each interest rate swap will be accrued on
a daily basis and an amount of liquid assets, such as cash, U.S. government
securities or other liquid high grade debt securities, having an aggregate net
asset value at least equal to such accrued excess will be maintained in a
segregated account by the Fund's custodian. A Fund will not enter into any
interest rate swap unless the unsecured commercial paper, senior debt, or claims
paying ability of the other party is rated, with respect to the Enhanced Income
and Total Return Advantage Funds, either "A" or "A-1" or better by S&P, Duff or
Fitch, or "A" or "P-1" or better by Moody's or, with respect to the GNMA Fund,
the claims paying ability of the other party is deemed creditworthy and any such
obligation the GNMA Fund may have under such an arrangement will be covered by
setting aside liquid high grade securities in a segregated account.

                  The Balanced Allocation, Total Return Advantage, GNMA, and
Enhanced Income Fund will only enter into swaps on a net basis, (i.e., the two
payment streams are netted out, with the Fund receiving or paying, as the case
may be, only the net amount of the two payments). Inasmuch as these transactions
are entered into for good faith hedging purposes, the Funds and their respective
Adviser or Sub-adviser believe that such obligations do not constitute senior
securities as defined in the 1940 Act and, accordingly, will not treat them as
being subject to the Fund's borrowing restrictions. The net amount of the
excess, if any, of the Fund's obligations over their



                                      -40-
<PAGE>   263

entitlements with respect to each swap will be accrued on a daily basis and an
amount of liquid assets, such as cash, U.S. government securities or other
liquid high grade debt securities, having an aggregate net asset value at least
equal to such accrued excess will be maintained in a segregated account by the
Fund's custodian.

                  If there is a default by the other party to a swap
transaction, the Fund involved will 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 in comparison with markets
for other similar instruments which are traded in the Interbank market.

ZERO COUPON OBLIGATIONS
- -----------------------

                  The Ohio Tax Exempt Bond, U.S. Government Income and Michigan
Municipal Bond Funds may invest in zero coupon obligations. Zero coupon
obligations are discount debt obligations that do not make periodic interest
payments although income is generally imputed to the holder on a current basis.
Such obligations may have higher price volatility than those which require the
payment of interest periodically. The Adviser will consider the liquidity needs
of the Fund when any investment in zero coupon obligations is made.

INCOME PARTICIPATION LOANS
- --------------------------

                  The Balanced Allocation, Total Return Advantage, Intermediate
Bond, and Enhanced Income Funds may make or acquire participations in privately
negotiated loans to borrowers. Frequently, such loans have variable interest
rates and may be backed by a bank letter of credit; in other cases they may be
unsecured. Such transactions may provide an opportunity to achieve higher yields
than those that may be available from other securities offered and sold to the
general public.

                  Privately arranged loans, however, will generally not be rated
by a credit rating agency and will normally be liquid, if at all, only through a
provision requiring repayment following demand by the lender. Such loans made by
a Fund may have a demand provision permitting the Fund to require repayment
within seven days. Participations in such loans, however, may not have such a
demand provision and may not be otherwise marketable. Recovery of an investment
in any such loan that is illiquid and payable on demand will depend on the
ability of the borrower to meet an obligation for full repayment of principal
and payment of accrued interest within the demand period, normally seven days or
less (unless the Fund determines that a particular loan issue, unlike most such
loans, has a readily available market). As it deems appropriate, the Board of
Trustees of the Trust will establish procedures to monitor the credit standing
of each such borrower, including its ability to honor contractual payment
obligations.



                                      -41-
<PAGE>   264

CERTIFICATES OF PARTICIPATION
- -----------------------------

                  The Michigan Municipal Bond Fund may purchase Michigan
Municipal Securities in the form of "certificates of participation" which
represent undivided proportional interests in lease payments by a governmental
or nonprofit entity. The Tax-Exempt Funds may also purchase certificates of
participation. The municipal leases underlying the certificates of participation
in which the Fund invests will be subject to the same quality rating standards
applicable to Municipal Securities. Certificates of participation may be
purchased from a bank, broker-dealer or other financial institution. The lease
payments and other rights under the lease provide for and secure the payments on
the certificates.

                  Lease obligations may be limited by law, municipal charter or
the duration or nature of the appropriation for the lease and may be subject to
periodic appropriation. In particular, lease obligations, may be subject to
periodic appropriation. If the entity does not appropriate funds for future
lease payments, the entity cannot be compelled to make such payments.
Furthermore, a lease may provide that the certificate trustee cannot accelerate
lease obligations upon default; in such event, the trustee would only be able to
enforce lease payments as they became due. In the event of a default or failure
of appropriation, it is unlikely that the trustee would be able to obtain an
acceptable substitute source of payment. In addition, certificates of
participation are less liquid than other bonds because there is a limited
secondary trading market for such obligations.

WHEN-ISSUED SECURITIES
- ----------------------

The International Equity, Small Cap Value, Small Cap Growth, Equity Growth, Tax
Managed Equity, Core Equity, Equity Income, Balanced Allocation, Total Return
Advantage, Bond, Intermediate Bond, GNMA, Enhanced Income, Ohio Municipal Money
Market, Pennsylvania Tax Exempt Money Market, Tax Exempt Money Market, Mid Cap
Growth and U.S. Government Income Funds may purchase securities (Municipal
Securities in the case of the Ohio Tax Exempt Bond, Pennsylvania Municipal Bond,
National Tax Exempt Bond and Michigan Municipal Funds) on a "when-issued" basis
(i.e., for delivery beyond the normal settlement date at a stated price and
yield). The Funds do not intend to purchase when-issued securities for
speculative purposes but only for the purpose of acquiring portfolio securities.
In when-issued and delayed delivery transactions, a Fund relies on the seller to
complete the transaction; its failure to do so may cause the Fund to miss a
price or yield considered to be attractive. One form of when-issued or delayed
delivery security that the GNMA and Bond Funds may purchase is a "to be
announced" (TBA) mortgage-backed security. A TBA transaction arises when a
mortgage-backed security, such as a GNMA pass-through security, is purchased or
sold with the specific pools that will constitute that GNMA pass-through
security to be announced on a future settlement date.

                  When a Fund agrees to purchase when-issued securities, the
custodian sets aside cash or liquid portfolio securities equal to the amount of
the commitment in a separate account. Normally, the custodian will set aside
portfolio securities to satisfy a purchase commitment, and in such a case a Fund
may be required subsequently to place additional assets in the separate account
in order to ensure that the value of the account remains equal to the amount of
the Fund's



                                      -42-
<PAGE>   265

commitment, marked to market daily. It is likely that a Fund's net assets will
fluctuate to a greater degree when it sets aside portfolio securities to cover
such purchase commitments than when it sets aside cash. Because a Fund will set
aside cash or liquid assets to satisfy its purchase commitments in the manner
described, the Fund's liquidity and ability to manage its portfolio might be
affected in the event its commitments to purchase when-issued securities ever
exceeded 25% of the value of its total assets.

                  When a Fund engages in when-issued transactions, it relies on
the seller to consummate the trade. Failure of the seller to do so may result in
the Fund's incurring a loss or missing an opportunity to obtain a price
considered to be advantageous. A Fund receives no income from when-issued or
delayed settlement securities prior to delivery of such securities.

SHORT-TERM OBLIGATIONS
- ----------------------

                  The International Equity, Small Cap Value, Small Cap Growth,
Equity Growth, Tax Managed Equity, Core Equity, Equity Index, Equity Income,
Balanced Allocation, Total Return Advantage, Bond, Intermediate Bond, GNMA,
Enhanced Income, and U.S. Government Income Funds may hold temporary cash
balances which may be invested in various short-term obligations (with
maturities of 18 months or less, 12 months in the case of the U.S. Government
Income Fund) such as domestic and foreign commercial paper, bankers'
acceptances, certificates of deposit and demand and time deposits of domestic
and foreign branches of U.S. banks and foreign banks, U.S. government
securities, repurchase agreements, reverse repurchase agreements and (GICs). The
Equity Index Fund cannot invest in foreign commercial paper and GICs. A Fund may
invest no more than 5% of its net assets in variable and floating rate
obligations. During temporary defensive periods, each Fund may hold up to 100%
of its total assets in these types of obligations.

                  In the case of repurchase agreements, default or bankruptcy of
the seller may expose a Fund to possible loss because of adverse market action
or delays connected with the disposition of the underlying obligations. Further,
it is uncertain whether a Fund would be entitled, as against a claim by such
seller or its receiver or trustee in bankruptcy, to retain the underlying
securities. Reverse repurchase agreements involve the risk that the market value
of the securities held by a Fund may decline below the price of the securities
it is obligated to repurchase.

                  Investments include commercial paper and other short-term
promissory notes issued by corporations (including variable and floating rate
instruments) must be rated at the time of purchase "A-2" or better by S&P,
"Prime-2" or better by Moody's, "F-2" or better by Fitch, "Duff 2" or better by
Duff or, determined by the adviser to be of comparable quality pursuant to
guidelines approved by the Trust's Board of Trustees. In addition, the
International Equity, Small Cap Growth, Tax Managed Equity, Core Equity,
Balanced Allocation, Total Return Advantage, Intermediate Bond and Enhanced
Income Funds may invest in Canadian Commercial Paper (CCP), which is commercial
paper issued by a Canadian corporation or a Canadian counterpart of a U.S.
corporation, and in Europaper, which is U.S. dollar denominated commercial paper
of a foreign



                                      -43-
<PAGE>   266

issuer. Each Fund may also acquire zero coupon obligations, which have greater
price volatility than coupon obligations and which will not result in the
payment of interest until maturity.

                  Bank obligations include bankers' acceptances and negotiable
certificates of deposit, and non-negotiable demand and time deposits issued for
a definite period of time and earning a specified return by a U.S. bank which is
a member of the Federal Reserve System. Bank obligations also include U.S.
dollar denominated bankers' acceptances and certificates of deposit and time
deposits issued by foreign branches of U.S. banks or foreign banks. Investment
in bank obligations is limited to the obligations of financial institutions
having more than $1 billion in total assets at the time of purchase. The
International Equity, Small Cap Growth, Tax Managed Equity, Core Equity,
Balanced Allocation, Total Return Advantage, Intermediate Bond and Enhanced
Income Funds may also make interest bearing savings deposits in commercial and
savings banks not in excess of 5% of its total assets. Investment in
non-negotiable time deposits is limited to no more than 5% of the Fund's total
assets at the time of purchase.

                  The Balanced Allocation, Total Return Advantage, Intermediate
Bond and Enhanced Income Funds may also make limited investments in (GIC) issued
by U.S. insurance companies. When investing in GICs, a Fund makes cash
contributions to a deposit fund or an insurance company's general account. The
insurance company then credits to that Fund monthly a guaranteed minimum
interest which is based on an index. The insurance company may assess periodic
charges against a GIC for expense and service costs allocable to it, and the
charges will be deducted from the value of the deposit fund. A Fund will
purchase a GIC only when its Adviser or Sub-adviser has determined, under
guidelines established by the Board of Trustees, that the GIC presents minimal
credit risks to the Fund and is of comparable quality to instruments that are
rated high quality by one or more rating agencies. In the case of the Balanced
Allocation Fund, because the Fund may not receive the principal amount of a GIC
from the insurance company on sixty days' notice or less, the GIC is considered
an illiquid investment, and, together with other instruments in the Fund which
are not readily marketable will not exceed 15% of the Fund's net assets.

                  The Mid Cap Growth Fund may hold temporary cash balances which
may be invested in various short-term obligations (with maturities of 12 months
or less) such as domestic and foreign commercial paper, bankers' acceptances,
certificates of deposit and demand and time deposits of domestic and foreign
branches of U.S. banks and foreign banks, U.S. government securities, repurchase
agreements, reverse repurchase agreements and GICs.

                  The Balanced Allocation and U.S. Government Income Funds may
engage in short-term trading and may sell securities which have been held for
periods ranging from several months to less than a day. The object of such
short-term trading is to increase the potential for capital appreciation and/or
income by making portfolio changes in anticipation of expected movements in
interest rates or security prices or in order to take advantage of what the
Fund's Adviser believes is a temporary disparity in the normal yield
relationship between two securities. Any such trading would increase the Fund's
turnover rate and its transaction costs. Higher portfolio turnover may result in
increased taxable gains to shareholders (see "Additional Information Concerning
Taxes" below) and increased expenses paid by the Fund due to



                                      -44-
<PAGE>   267

transaction costs. Under normal market conditions, the Balanced Allocation and
U.S. Government Income's portfolio turnover are not expected to exceed 200%.

MONEY MARKET INSTRUMENTS
- ------------------------

                  The Money Market Fund may invest in "money market"
instruments, including bank obligations and commercial paper. The Ohio Municipal
Money Market and Pennsylvania Tax Exempt Money Market Funds may also invest,
from time to time, a portion of their assets for temporary defensive or other
purposes in such taxable money market instruments.

                  Bank obligations include bankers' acceptances, negotiable
certificates of deposit, and non-negotiable time deposits issued for a definite
period of time and earning a specified return by a U.S. bank which is a member
of the Federal Reserve System. Bank obligations also include U.S. dollar
denominated bankers' acceptances, certificates of deposit and time deposits
issued by foreign branches of U.S. banks or foreign banks. Investment in bank
obligations is limited to the obligations of financial institutions having more
than $1 billion in total assets at the time of purchase. The Money Market Fund
may also make interest bearing savings deposits in commercial and savings banks
not in excess of 5% of its total assets. Investment in non-negotiable time
deposits is limited to no more than 5% of the Fund's total assets at the time of
purchase.

                  Investments in commercial paper and other short-term
promissory notes issued by corporations (including variable and floating rate
instruments) must be rated at the time of purchase "A-2" or better by S&P,
"Prime-2" or better by Moody's, "F-2" or better by Fitch, "Duff 2" or better by
Duff or, if not rated, determined by the Adviser to be of comparable quality
pursuant to guidelines approved by the Trust's Board of Trustees. Investments
may also include corporate notes. In addition, the Money Market Fund may invest
in Canadian Commercial Paper ("CCP"), which is U.S. dollar denominated
commercial paper issued by a Canadian corporation or a Canadian counterpart of a
U.S. corporation, and in Europaper, which is U.S. dollar denominated commercial
paper of a foreign issuer. The Money Market Fund may acquire zero coupon
obligations, which have greater price volatility than coupon obligations and
which will not result in the payment of interest until maturity.

                  Investments in the obligations of foreign branches of U.S.
banks, foreign banks and other foreign issuers may subject the Money Market Fund
to additional investment risks, including future political and economic
developments, the possible imposition of withholding taxes on interest income,
possible seizure or nationalization of foreign deposits, the possible
establishment of exchange controls, or the adoption of other foreign
governmental restrictions which might adversely affect the payment of principal
and interest on such obligations. In addition, foreign branches of U.S. banks
and foreign banks may be subject to less stringent reserve requirements and to
different accounting, auditing, reporting, and recordkeeping standards than
those applicable to domestic branches of U.S. banks. The Money Market Fund will
invest in the obligations of foreign banks or foreign branches of U.S. banks
only when the Adviser believes that the credit risk with respect to the
instrument is minimal.



                                      -45-
<PAGE>   268

                  The Money Market Fund may also make limited investments in
GICs issued by U.S. insurance companies. The Fund will purchase a GIC only when
the Adviser has determined, under guidelines established by the Board of
Trustees, that the GIC presents minimal credit risks to the Fund and is of
comparable quality to instruments that are rated high quality by certain
nationally recognized statistical rating organizations.

GOVERNMENT SECURITIES
- ---------------------

                  The Treasury Money Market and Treasury Plus Money Market Funds
may only invest in direct obligations of the U.S. Treasury and investment
companies that invest only in such obligations. Examples of the types of U.S.
government obligations that may be held by the Balanced Allocation, Total Return
Advantage, Bond, Intermediate Bond, GNMA, Enhanced Income, Ohio Municipal Money
Market, Pennsylvania Tax Exempt Money Market, Tax Exempt Money Market, Money
Market, Government Money Market, Mid Cap Growth, U.S. Government Income, and
Michigan Municipal Bond Funds include, in addition to Treasury Bills, the
obligations of Federal Home Loan Banks, Federal Farm Credit Banks, Federal Land
Banks, the Federal Housing Administration, Farmers Home Administration,
Export-Import Bank of the United States, Small Business Administration,
Government National Mortgage Association, General Services Administration,
Student Loan Marketing Association, Central Bank for Cooperatives, Federal Home
Loan Mortgage Corporation, Federal Intermediate Credit Banks and Maritime
Administration. Some of these obligations are supported by the full faith and
credit of the U.S. Treasury, such as obligations issued by the Government
National Mortgage Association. Others, such as those of the Export-Import Bank
of the United States, are supported by the right of the issuer to borrow from
the U.S. Treasury; others, such as those of the Federal National Mortgage
Association, are supported by the discretionary authority of the U.S. Government
to purchase the agency's obligations; and still others, such as those of the
Student Loan Marketing Association, are supported only by the credit of the
agency or instrumentality issuing the obligation. No assurance can be given that
the U.S. Government would provide financial support to U.S. Government-sponsored
agencies or instrumentalities if it is not obligated to do so by law. Some of
these investments may be variable or floating rate instruments. See "Variable
and Floating Rate Obligations." The Ohio Municipal Money Market, Pennsylvania
Tax Exempt Money Market, Tax Exempt Money Market, Money Market and Government
Money Market Funds will invest in the obligations of such agencies or
instrumentalities only when the Adviser believes that their credit risk with
respect thereto is minimal.

U.S. TREASURY OBLIGATIONS AND RECEIPTS
- --------------------------------------

                  The Balanced Allocation, Total Return Advantage, Bond,
Intermediate Bond, GNMA, Enhanced Income, Money Market, Mid Cap Growth, U.S.
Government Income and Michigan Municipal Bond Funds may invest in obligations
issued or guaranteed by the U.S. government or its agencies. The Fund may invest
in U.S. Treasury obligations consisting of bills, notes and bonds issued by the
U.S. Treasury, and separately traded interest and principal component parts of
such obligations that are transferable through the Federal book-entry system
known as STRIPS (Separately Traded Registered Interest and Principal
Securities).



                                      -46-
<PAGE>   269

                  The Fund may invest in separately traded interest and
principal component parts of the U.S. Treasury obligations that are issued by
banks or brokerage firms and are created by depositing U.S. Treasury obligations
into a special account at a custodian bank. The custodian holds the interest and
principal payments for the benefit of the registered owners of the certificates
of receipts. The custodian arranges for the issuance of the certificates or
receipts evidencing ownership and maintains the register. Receipts include
Treasury Receipts (TRs), Treasury Investment Growth Receipts (TIGRs), Liquid
Yield Option Notes (LYONs), and Certificates of Accrual on Treasury Securities
(CATS). TIGRs, LYONs and CATS are interests in private proprietary accounts
while TR's are interests in accounts sponsored by the U.S. Treasury.

                  Securities denominated as TRs, TIGRs, LYONs and CATS are sold
as zero coupon securities which means that they are sold at a substantial
discount and redeemed at face value at their maturity date without interim cash
payments of interest or principal. This discount is accreted over the life of
the security, and such accretion will constitute the income earned on the
security for both accounting and tax purposes. Because of these features, such
securities may be subject to greater interest rate volatility than interest
paying investments.

STAND-BY COMMITMENTS
- --------------------

                  The Tax-Exempt Funds, Ohio Municipal Money Market,
Pennsylvania Tax Exempt Money Market, and Tax Exempt Money Market Funds may
acquire stand-by commitments. Under a stand-by commitment, a dealer agrees to
purchase at a Fund's option specified Michigan Municipal Securities at a
specified price. Stand-by commitments acquired by the Fund must be of high
quality as determined by any Rating Agency, or, if not rated, must be of
comparable quality as determined by the Adviser. The Fund acquires stand-by
commitments solely to facilitate portfolio liquidity and does not intend to
exercise its rights thereunder for trading purposes.

DERIVATIVE INSTRUMENTS
- ----------------------

                  The International Equity, Small Cap Value, Small Cap Growth,
Equity Growth, Tax Managed Equity, Core Equity, Equity Index, Equity Income,
Balanced Allocation, Total Return Advantage, Bond, Intermediate Bond, GNMA,
Enhanced Income, Money Market, Mid Cap Growth, and U.S. Government Income Funds
may purchase certain "derivative" instruments. Derivative instruments are
instruments that derive value from the performance of underlying securities,
interest or currency exchange rates, or indices, and include (but are not
limited to) futures contracts, options, forward currency contracts and
structured debt obligations (including collateralized mortgage obligations
("CMOs"), various floating rate instruments and other types of securities).

                  Like all investments, derivative instruments involve several
basic types of risks which must be managed in order to meet investment
objectives. The specific risks presented by derivatives include, to varying
degrees, market risk in the form of underperformance of the underlying
securities, exchange rates or indices; credit risk that the dealer or other
counterparty to the transaction will fail to pay its obligations; volatility and
leveraging risk that, if interest or exchange rates change adversely, the value
of the derivative instrument will decline more than the securities, rates or
indices on which it is based; liquidity risk that the Fund will be unable to
sell a derivative instrument when it wants because of lack of market depth or
market disruption; pricing risk that the value of a derivative instrument (such
as an option) will not correlate exactly to the value of the underlying
securities, rates or indices on which it is based; extension risk that the
expected duration of an instrument may increase or decrease; and operations risk
that loss will occur as a result of inadequate systems and controls, human error
or otherwise. Some derivative instruments are more complex than others, and for
those instruments that have been developed recently, data are lacking regarding
their actual performance over complete market cycles.

                  The risk to the International Equity, Small Cap Value, Small
Cap Growth, Equity Growth, Tax Managed Equity, Core Equity, Equity Index, Equity
Income, Mid Cap Growth and U.S. Government Income Funds due to the use of
derivatives in the equity portion of the Fund's portfolio of investments will be
limited to 10% of such investments at the time of the derivative transaction.

                  With respect to the fixed income portion of the Fund's
investments, the Fund's Adviser has determined that the risk features that must
distinguish derivatives from other investment instruments (and which heavily
influence the market, volatility and leveraging, liquidity, and pricing risks
referred to above) can be described generally as "structural risk." Structural
risk refers to the contractual features of an investment that can cause its
total return to vary with changes in interest rates or other variables.
Structural risk is not unique to derivatives, but because derivatives often are
created through the intricate division of the cash flows of the underlying
security, they can (but do not necessarily) present a high degree of structural
risk. Structural risk can arise from variations in coupon levels, principal,
and/or average life.



                                      -48-
<PAGE>   271

                  The Adviser has adopted the following internal policies
concerning management of the structural risk inherent in derivative instruments
in the fixed income portion of the Fund's portfolio. The risk to the Fund due to
the use of such derivatives will be limited to the principal invested in such
instruments. When the Fund engages in short sales "against the box," risk of
loss will be limited to the value of the securities "in the box." The adviser
does NOT presently intend to invest in the following types of derivatives which
are structured instruments, such as range notes, dual index notes, leveraged or
deleveraged bonds, inverse floaters, index amortizing notes and other structured
instruments having similar cash flow characteristics.

                  The cash equivalent portion of the Fund's portfolio of
investments is managed with an emphasis on safety and high credit quality. This
requires that liquidity risk and market risk or interest rate risk, as well as
credit risk, be held to minimal levels. The Adviser has determined that many
types of floating rate and variable rate instruments, commonly referred to as
"derivatives," are considered to be potentially volatile. These derivative
instruments are structured in a way that may not allow them to reset to par at
an interest rate adjustment date. Accordingly, the Adviser has adopted the
following policies with respect to this portion of the Fund's assets.

                  The following types of derivative instruments ARE NOT
permitted investments for the cash equivalent portion of the Fund's portfolio of
investments:

                  - leveraged or deleveraged floaters (whose interest rate reset
provisions are based on a formula that magnifies the effect of changes in
interest rates);

                  - range floaters (which do not pay interest if market interest
rates move outside of a specified range);

                  - dual index floaters (whose interest rate reset provisions
are tied to more than one index so that a change in the relationship between
these indices may result in the value of the instrument falling below face
value);

                  - inverse floaters (which reset in the opposite direction of
their index); and

                  - any other structured instruments having cash flow
characteristics that can create potential market volatility similar to the
instruments listed above.

Additionally, the cash equivalent portion of the Fund's portfolio will not be
invested in instruments indexed to longer than one-year rates, or in instruments
whose interest rate reset provisions are tied to an index that materially lags
short-term interest rates, such as "COFI floaters."

                  At the present time, the only derivative investments that have
been determined to be suitable for the cash equivalent portion of the Fund's
portfolio are:

                  - securities based on short-term, fixed-rate contracts; and



                                      -49-
<PAGE>   272

                  - floating-rate or variable-rate securities whose interest
rates reset based on changes in standard money market rate indices such as U.S.
government Treasury bills, London Interbank Offered Rate, published commercial
paper rates, or federal funds rates.

                  The risk to the Fund due to the use of derivatives in the cash
equivalent portion of its assets will be limited to the principal invested in
such instruments.

                  The Adviser will evaluate the risks presented by the
derivative instruments purchased by the Fund, and will determine, in connection
with day-to-day management of the Fund, how they will be used in furtherance of
the Fund's investment objective.

                  The Intermediate Bond Fund may invest in moderate structural
risk derivatives containing features which can modestly or moderately alter the
timing and/or amount of principal return and/or amount of income return. This
would include, for example, investments that are subject to normal prepayment
variances experienced in mortgage pass-through securities. Periodic occurrence
of this degree of structural risk would not be expected to materially impact
overall Fund returns relative to its investment objective.

                  The Intermediate Bond Fund will NOT invest in high structural
risk derivatives whose duration (and hence return) can vary widely depending on
moves in interest rates or other contractual variables. Generally, these are
instruments which are deemed to have a high sensitivity to changes in interest
rates, which could materially alter the effective duration or coupon and return
of the instruments.

                  The Intermediate Bond Fund may invest in mortgage-backed
derivative securities, including CMOs, provided that they are not identified by
the advisers as "high risk securities" by certain quantitative tests that are
generally accepted standards in the investment industry.

                  Other derivative instruments that are suitable for investment
include: asset-backed securities such as those backed by automobile loans or
credit card receivables. All such securities, however, must conform to the
structural risk standards stated above (i.e. not present high structural risk).

                  The Adviser does NOT presently intend to invest in the
following types of derivatives on behalf of the Fund:

- -        exchange rate-related securities

- -        forward currency exchange contracts

- -        interest rate swaps

- -        futures contracts and related options

                                      -50-
<PAGE>   273

- -        structured instruments, such as range notes, dual index notes,
         leveraged or deleveraged bonds, inverse floaters, index amortizing
         notes and other structured instruments having similar cash flow
         characteristics

         The Total Return Advantage and Enhanced Income Funds may invest in
derivative instruments having either moderate structural risk or high structural
risk characteristics (as described above in the section pertaining to the
Intermediate Bond Fund). There are no policy restrictions on specific types of
derivative instruments in which the Funds are permitted to invest. However,
structural risk is controlled by adherence to specific overall Fund parameters.
The Funds are managed in accordance with a policy goal that constrains the
potential variability of overall Fund duration and total return in relation to
specified investment performance benchmarks. Fund exposure to derivative
instruments having high structural risk characteristics is targeted at a maximum
of 5.0% of each Fund's net assets with no individual position greater than 1.0%
of each Fund. Variability in total Fund duration caused by these securities is
targeted not to exceed 0.1 years in any one calendar year.

                  The Adviser of the Bond Fund does NOT presently intend to
invest in the following types of derivatives which are structured instruments,
such as range notes, dual index notes, leveraged or deleveraged bonds, inverse
floaters, index amortizing notes and other structured instruments having similar
cash flow characteristics.

         The Adviser has adopted the following internal policy concerning
management of the structural risk inherent in derivative instruments on behalf
of the GNMA Fund:

                  The Adviser does not presently intend to invest in the
following types of derivatives on behalf of the GNMA Fund:

- -        exchange rate-related securities

- -        forward currency exchange contracts

- -        structured instruments, such as range notes, dual index notes,
         leveraged or deleveraged bonds, inverse floaters, index amortizing
         notes and other structured instruments having similar cash flow
         characteristics

TAX-EXEMPT DERIVATIVES AND OTHER MUNICIPAL SECURITIES
- -----------------------------------------------------

                  The Ohio Municipal Money Market, Pennsylvania Tax Exempt Money
Market and Tax Exempt Money Market Funds may invest in tax-exempt derivative
securities relating to Municipal Securities, including tender option bonds,
participations, beneficial interests in trusts and partnership interests. (See
generally "Derivative Instruments" above.)

                  Opinions relating to the validity of Municipal Securities and
to the exemption of interest thereon from federal income tax are rendered by
bond counsel to the respective issuers at the time of issuance, and opinions
relating to the validity of and the tax-exempt status of



                                      -51-
<PAGE>   274

payments received by the Ohio Municipal Money Market, Pennsylvania Tax Exempt
Money Market and Tax Exempt Money Market Funds from tax-exempt derivative
securities are rendered by counsel to the respective sponsors of such
securities. The Funds and the Adviser will rely on such opinions and will not
review independently the underlying proceedings relating to the issuance of
Municipal Securities, the creation of any tax-exempt derivative securities, or
the bases for such opinions.

SECURITIES OF OTHER INVESTMENT COMPANIES
- ----------------------------------------

                  Subject to 1940 Act limitations and pursuant to applicable SEC
requirements, the Funds may invest in securities issued by other investment
companies which invest in high quality, short-term debt securities and which
determine their net asset value per share based on the amortized cost or
penny-rounding method. As a shareholder of another investment company, the Fund
would bear, along with other shareholders, its pro rata portion of that
company's expenses, including advisory fees. These expenses would be in addition
to the advisory and other expenses that the Fund bears directly in connection
with its own operations. Investment companies in which the Fund may invest may
also impose a sales or distribution charge in connection with the purchase or
redemption of their shares and other types of commissions or charges. Such
charges will be payable by a Fund and, therefore, will be borne indirectly by
its shareholders.

                  Each Fund may invest in securities issued by other investment
companies as described in the Prospectus. Each Fund currently intends to limit
its investments in securities issued by other investment companies so that, as
determined immediately after a purchase of such securities is made: (i) not more
than 5% of the value of the Fund's total assets will be invested in the
securities of any one investment company; (ii) not more than 10% of the value of
its total assets will be invested in the aggregate in securities of investment
companies as a group; and (iii) not more than 3% of the outstanding voting stock
of any one investment company will be owned by the Fund or by the Trust as a
whole.

                  With regard to the Tax-Exempt Funds and the Money Market
Funds, not more than 10% of the outstanding voting stock of any one investment
company will be owned in the aggregate by the Fund and other investment
companies advised by the Adviser.

                  In addition, the International Equity Fund may purchase shares
of investment companies investing primarily in foreign securities, including
"country funds" which have portfolios consisting exclusively of securities of
issuers located in one foreign country. Such "country funds" may be either
open-end or closed-end investment companies, and may include a portfolio or
portfolios of The CountryBaskets Index Fund, Inc. (CountryBaskets), a
registered, open-end management investment company that, through its portfolios,
seeks to provide investment results that substantially correspond to the price
and yield performance of a broad-based index of publicly traded equity
securities in a particular country, geographic region or industry sector.

                  The International Equity Fund may also purchase World Equity
Benchmark Shares issued by The Foreign Fund, Inc. (WEBS) and similar securities
of other issuers. WEBS



                                      -52-
<PAGE>   275

are shares of an investment company that invests substantially all of its assets
in securities included in the Morgan Stanley Capital International indices for
specific countries. Because the expense associated with an investment in WEBS
can be substantially lower than the expense of small investments directly in the
securities comprising the indices it seeks to track, the Adviser believes that
investments in WEBS of countries that are included in the EAFE Index can provide
a cost-effective means of diversifying the Fund's assets across a broader range
of equity securities.

                  WEBS are listed on the American Stock Exchange (AMEX), and
were initially offered to the public in 1996. The market prices of WEBS are
expected to fluctuate in accordance with both changes in the net asset values of
their underlying indices and supply and demand of WEBS on the AMEX. To date,
WEBS have traded at relatively modest discounts and premiums to their net asset
values. However, WEBS have a limited operating history, and information is
lacking regarding the actual performance and trading liquidity of WEBS for
extended periods or over complete market cycles. In addition, there is no
assurance that the requirements of the AMEX necessary to maintain the listing of
WEBS will continue to be met or will remain unchanged.

                  In the event substantial market or other disruptions affecting
WEBS or CountryBaskets should occur in the future, the liquidity and value of
the International Equity Fund's shares could also be substantially and adversely
affected, and the Fund's ability to provide investment results approximating the
performance of securities in the EAFE could be impaired. If such disruptions
were to occur, the Fund could be required to reconsider the use of WEBS,
CountryBaskets or other "country funds" as part of its investment strategy.

                  As a shareholder of another investment company, a Fund would
bear, along with other shareholders, its pro rata portion of that company's
expenses, including advisory fees. These expenses would be in addition to the
advisory and other expenses that a Fund bears directly in connection with its
own operations. Investment companies in which a Fund may invest may also impose
a sales or distribution charge in connection with the purchase or redemption of
their shares and other types of commissions or charges. Such charges will be
payable by the Fund and, therefore, will be borne indirectly by its
shareholders.

MUNICIPAL SECURITIES
- --------------------

                  The Ohio Tax Exempt Bond, Pennsylvania Municipal Bond and
National Tax Exempt Bond and Michigan Municipal Bond Funds may invest in
Municipal Securities. The two principal classifications of Municipal Securities
consist of "general obligation" and "revenue" issues. Municipal Bonds include
debt obligations issued by governmental entities to obtain funds for various
public purposes, including the construction of a wide range of public
facilities, the refunding of outstanding obligations, and the extension of
loans to public institutions and facilities.



                                      -53-
<PAGE>   276

                  Municipal Securities that are payable only from the revenues
derived from a particular facility may be adversely affected by federal or state
laws, regulations or court decisions which make it more difficult for the
particular facility to generate revenues sufficient to pay such interest and
principal, including, among others, laws, decisions and regulations which limit
the amount of fees, rates or other charges which may be imposed for use of the
facility or which increase competition among facilities of that type or which
limit or otherwise have the effect of reducing the use of such facilities
generally, thereby reducing the revenues generated by the particular facility.
Municipal Securities, the payment of interest and principal on which is insured
in whole or in part by a governmentally created fund, may be adversely affected
by laws or regulations which restrict the aggregate proceeds available for
payment of principal and interest in the event of a default on such municipal
securities. Similarly, the payment of interest and principal on Municipal
Securities may be adversely affected by respective state laws which limit the
availability of remedies or the scope of remedies available in the event of a
default on such municipal securities. Because of the diverse nature of such laws
and regulations and the impossibility of either predicting in which specific
Municipal Securities the Funds will invest from time to time or predicting the
nature or extent of future judicial interpretations or changes in existing laws
or regulations or the future enactment or adoption of additional laws or
regulations, it is not presently possible to determine the impact of such laws,
regulations and judicial interpretations on the securities in which the Funds
may invest and, therefore, on the shares of the Fund.

                  There are, of course, variations in the quality of Municipal
Securities both within a particular classification and between classifications,
and the yields on Municipal Securities depend upon a variety of factors,
including the financial condition of the issuer, the general conditions of the
municipal bond market, the size of a particular offering, the maturity of the
obligation and the rating of the issue. The ratings of rating agencies represent
their opinions as to the quality of Municipal Securities. It should be
emphasized, however, that ratings are general and are not absolute standards of
quality, and Municipal Securities with the same maturity, interest rate and
rating may have different yields while Municipal Securities of the same maturity
and interest rate with different ratings may have the same yield. Subsequent to
its purchase by a Fund, an issue of Municipal Securities may cease to be rated
or its rating may be reduced below the minimum rating required for purchase by
the Funds. The Funds' adviser will consider such an event in determining whether
they should continue to hold the obligation.

                  The payment of principal and interest on most Municipal
Securities purchased by the Funds will depend upon the ability of the issuers to
meet their obligations. An issuer's obligations under its Municipal Securities
are subject to the provisions of bankruptcy, insolvency and other laws affecting
the rights and remedies of creditors, such as the Federal Bankruptcy Code,



                                      -54-
<PAGE>   277

and laws, if any, which may be enacted by federal or state legislatures
extending the time for payment of principal or interest, or both, or imposing
other constraints upon enforcement of such obligations or upon the ability of
municipalities to levy taxes. The power or ability of an issuer to meet its
obligations for the payment of interest or the principal of its Municipal
Securities may be materially adversely affected by litigation or other
conditions.

                  Certain Municipal Securities held by the Funds may be insured
at the time of issuance as to the timely payment of principal and interest. The
insurance policies will usually be obtained by the issuer or original purchaser
of the Municipal Securities at the time of their original issuance. In the event
that the issuer defaults on interest or principal payments, the insurer of the
obligation is required to make payment to the bondholders upon proper
notification. There is, however, no guarantee that the insurer will meet its
obligations. In addition, such insurance will not protect against market
fluctuations caused by changes in interest rates and other factors.

                  Municipal notes in which the Funds may invest include, but are
not limited to, general obligation notes, tax anticipation notes (notes sold to
finance working capital or capital facilities needs of the issuer in
anticipation of receiving taxes on a future date), revenue anticipation notes
(notes sold to provide needed cash prior to receipt of expected non-tax revenues
from a specific source), bond anticipation notes, certificates of indebtedness,
demand notes and construction loan notes.

                  The Funds invest in Municipal Securities which at the time of
purchase are rated in one of the four highest rating categories by an NRSRO for
bonds and in one of the two highest rating categories by an NRSRO for money
market securities.

                  Securities that are unrated at the time of purchase will be
determined to be of comparable quality by the Funds' adviser pursuant to
guidelines approved by the Trust's Board of Trustees. If the rating of an
obligation held by a Fund is reduced below its rating requirements, the Fund
will sell the obligation when the adviser believes that it is in the best
interests of the Fund to do so. The applicable ratings are more fully described
in the Appendix.

Special Considerations Regarding Investment in Ohio Municipal Securities

                  As described in the Prospectus, the Ohio Tax Exempt Bond Fund
and Ohio Municipal Money Market Fund will invest most of its net assets in
securities issued by or on behalf of (or in certificates of participation in
lease-purchase obligations of) the State of Ohio, political subdivisions of the
State, or agencies or instrumentalities of the State or its political
subdivisions (Ohio Obligations). The Ohio Tax Exempt Bond Fund is therefore
susceptible to general or particular economic, political or regulatory factors
that may affect issuers of Ohio Obligations. The following information
constitutes only a brief summary of some of the many complex factors that may
have an effect. The information does not apply to "conduit" obligations on
which the public issuer itself has no financial responsibility. This
information is derived from official statements of certain Ohio issuers
published in connection



                                      -55-
<PAGE>   278

with their issuance of securities and from other publicly available information,
and is believed to be accurate. No independent verification has been made of any
of the following information.

                  Generally, the creditworthiness of Ohio Obligations of local
issuers is unrelated to that of obligations of the State itself, and the State
has no responsibility to make payments on those local obligations.

                  There may be specific factors that at particular times apply
in connection with investment in particular Ohio Obligations or in those
obligations of particular Ohio issuers. It is possible that the investment may
be in particular Ohio Obligations, or in those of particular issuers, as to
which those factors apply. However, the information below is intended only as a
general summary, and is not intended as a discussion of any specific factors
that may affect any particular obligation or issuer.

                  While diversifying more into the service and other
non-manufacturing areas, the Ohio economy continues to rely in part on durable
goods manufacturing largely concentrated in motor vehicles and equipment, steel,
rubber products and household appliances. As a result, general economic
activity, as in many other industrially-developed states, tends to be more
cyclical than in some other states and in the nation as a whole. Agriculture is
an important segment of the economy, with over half the State's area devoted to
farming and approximately 16% of total employment in agribusiness.

                  In prior years, the State's overall unemployment rate was
commonly somewhat higher than the national figure. For example, the reported
1990 average monthly State rate was 5.7%, compared to the 5.5% national figure.
However, in recent years the State rates were below the national rates (4.3%
versus 4.5% in 1998). The unemployment rate and its effects vary among
geographic areas of the State.

                  There can be no assurance that future national, regional or
state-wide economic difficulties, and the resulting impact on State or local
government finances generally, will not adversely affect the market value of
Ohio Obligations held in the Ohio Tax Exempt Bond Fund or the ability of
particular obligors to make timely payments of debt service on (or lease
payments relating to) those Obligations.

                  The State operates on the basis of a fiscal biennium for its
appropriations and expenditures, and is precluded by law from ending its July 1
to June 30 fiscal year (FY) or fiscal biennium in a deficit position. Most State
operations are financed through the General Revenue Fund (GRF), for which the
personal income and sales-use taxes are the major sources. Growth and depletion
of GRF ending fund balances show a consistent pattern related to national
economic conditions, with the ending FY balance reduced during less favorable
and increased during more favorable economic periods. The State has
well-established procedures for, and has timely taken,



                                      -56-
<PAGE>   279

necessary actions to ensure resource/expenditure balances during less favorable
economic periods. Those procedures included general and selected reductions in
appropriations spending.

                  The 1992-93 biennium presented significant challenges to State
finances, successfully addressed. To allow time to resolve certain budget
differences an interim appropriations act was enacted effective July 1, 1991; it
included GRF debt service and lease rental appropriations for the entire
biennium, while continuing most other appropriations for a month. Pursuant to
the general appropriations act for the entire biennium, passed on July 11, 1991,
$200 million was transferred from the Budget Stabilization Fund (BSF, a cash and
budgetary management fund) to the GRF in FY 1992.

                  Based on updated results and forecasts in the course of that
FY, both in light of a continuing uncertain nationwide economic situation, there
was projected, and then timely addressed, an FY 1992 imbalance in GRF resources
and expenditures. In response, the Governor ordered most State agencies to
reduce GRF spending in the last six months of FY 1992 by a total of
approximately $184 million; the $100.4 million BSF balance and additional
amounts from certain other funds were transferred late in the FY to the GRF, and
adjustments were made in the timing of certain tax payments.

                  A significant GRF shortfall (approximately $520 million) was
then projected for FY 1993. It was addressed by appropriate legislative and
administrative actions, including the Governor's ordering $300 million in
selected GRF spending reductions and subsequent executive and legislative action
(a combination of tax revisions and additional spending reductions). The June
30, 1993 ending GRF fund balance was approximately $111 million, of which, as a
first step to replenishment, $21 million was deposited in the BSF.

                  None of the spending reductions were applied to appropriations
needed for debt service on or lease rentals relating to any State obligations.

                  The 1994-95 biennium presented a more affirmative financial
picture. Based on June 30, 1994 balances, an additional $260 million was
deposited in the BSF. The biennium ended June 30, 1995 with a GRF ending fund
balance of $928 million, of which $535.2 million was transferred into the BSF.
The significant GRF fund balance, after leaving in the GRF an unreserved and
undesignated balance of $70 million, was transferred to the BSF and other funds
including school assistance funds and, in anticipation of possible federal
program changes, a human services stabilization fund.

                  From a higher than forecast 1996-97 mid-biennium GRF fund
balance, $100 million was transferred for elementary and secondary school
computer network purposes and $30 million to a new State transportation
infrastructure fund. Approximately $400.8 million served as a basis for
temporary 1996 personal income tax reductions aggregating that amount. The
1996-97 biennium-ending GRF fund balance was $834.9 million. Of that, $250
million went to school building construction and renovation, $94 million to the
school computer network, $44.2 million for school textbooks and instructional
materials and a distance learning program, and $34 million to the BSF and the
$263 million balance to a State income tax reduction fund.



                                      -57-
<PAGE>   280

                  The GRF appropriations act for the 1998-99 biennium was passed
on June 25, 1997 and promptly signed (after selective vetoes) by the Governor.
All necessary GRF appropriations for State debt service and lease rental
payments then projected for the biennium were included in that act (and are
included in the pending House and Senate-passed appropriation bills for FY
2000-01). Subsequent legislation increased the FY 1999 GRF appropriation level
for elementary and secondary education, with the increase funded in part by
mandated small percentage reductions in State appropriations for various State
agencies and institutions. Expressly exempt from those reductions are all
appropriations for debt service, including lease rental payments.

                  The BSF had a June 8, 1999 balance of more than $906 million.

                  The State's incurrence or assumption of debt without a vote of
the people is, with limited exceptions, prohibited by current State
constitutional provisions. The State may incur debt, limited in amount to
$750,000, to cover casual deficits or failures in revenues or to meet expenses
not otherwise provided for. The Constitution expressly precludes the State from
assuming the debts of any local government or corporation. (An exception is made
in both cases for any debt incurred to repel invasion, suppress insurrection or
defend the State in war.)

                  By 15 constitutional amendments approved from 1921 to date
(the latest adopted in 1995) Ohio voters authorized the incurrence of State debt
and the pledge of taxes or excises to its payment. At June 8, 1999, almost $1.14
billion (excluding certain highway bonds payable primarily from highway use
receipts) of this debt was outstanding or awaiting delivery. The only such State
debt at that date still authorized to be incurred were portions of the highway
bonds, and the following: (a) up to $100 million of obligations for coal
research and development may be outstanding at any one time ($23.9 million
outstanding); (b) $240 million of obligations previously authorized for local
infrastructure improvements, no more than $120 million of which may be issued in
any calendar year (over $1 billion outstanding) and (c) up to $200 million in
general obligation bonds for parks, recreation and natural resources purposes
which may be outstanding at any one time ($112.7 million outstanding or awaiting
delivery, with no more than $50 million to be issued in any one year).

                  The electors in 1995 approved a constitutional amendment
extending the local infrastructure bond program (authorizing an additional $1.2
billion of State full faith and credit obligations to be issued over 10 years
for the purpose), and authorizing additional highway bonds (expected to be
payable primarily from highway use receipts). The latter supersedes the prior
$500 million outstanding authorization, and authorizes not more than $1.2
billion to be outstanding at any time and not more than $220 million to be
issued in a fiscal year.

                  The Constitution also authorizes the issuance of State
obligations for certain purposes, the owners of which do not have the right to
have excises or taxes levied to pay debt service. Those special obligations
include obligations issued by the Ohio Public Facilities Commission and the Ohio
Building Authority, and certain obligations issued by the State Treasurer, over
$5.2 billion of which were outstanding at June 8, 1999.



                                      -58-
<PAGE>   281

                  The General Assembly has placed on the November 1999 general
election ballot a proposed constitutional amendment relating to State debt. If
approved by the voters, it will authorize State general obligation debt to pay
costs of facilities for a system of common schools throughout the State and
facilities for state supported and assisted institutions of higher education.
That, and other debt represented by direct obligations of the State (such as
that authorized by the Ohio Public Facilities Commission and Ohio Building
Authority, and some authorized by the Treasurer), may not be issued if future FY
total debt service on those direct obligations to be paid from the GRF or net
lottery proceeds exceeds 5% of total estimated revenues of the State for the GRF
and from net State lottery proceeds during the FY of issuance.

                  Aggregate FY 1998 rental payments under various capital lease
and lease purchase agreements were approximately $9.1 million. In recent years,
State agencies have also participated in transportation and office building
projects that may have some local as well as State use and benefit, in
connection with which the State enters into lease purchase agreements with terms
ranging from 7 to 20 years. Certificates of participation, or special obligation
bonds of the State or a local agency, are issued that represent fractionalized
interests in or are payable from the State's anticipated payments. The State
estimates highest future FY payments under those agreements (as of June 8, 1999)
to be approximately $25.8 million (of which $22 million is payable from sources
other than the GRF, such as federal highway money distributions). State payments
under all those agreements are subject to biennial appropriations, with the
lease terms being two years subject to renewal if appropriations are made.

                  A 1990 constitutional amendment authorizes greater State and
political subdivision participation (including financing) in the provision of
housing. The General Assembly may for that purpose authorize the issuance of
State obligations secured by a pledge of all or such portion as it authorizes of
State revenues or receipts (but not by a pledge of the State's full faith and
credit).

                  A 1994 constitutional amendment pledges the full faith and
credit and taxing power of the State to meeting certain guarantees under the
State's tuition credit program which provides for purchase of tuition credits,
for the benefit of State residents, guaranteed to cover a specified amount when
applied to the cost of higher education tuition. (A 1965 constitutional
provision that authorized student loan guarantees payable from available State
moneys has never been implemented, apart from a "guarantee fund" approach funded
essentially from program revenues.)

                  State and local agencies issue obligations that are payable
from revenues from or relating to certain facilities (but not from taxes). By
judicial interpretation, these obligations are not "debt" within constitutional
provisions. In general, payment obligations under lease-purchase agreements of
Ohio public agencies (in which certificates of participation may be issued) are
limited in duration to the agency's fiscal period, and are renewable only upon
appropriations being made available for the subsequent fiscal period.

                  Local school districts in Ohio receive a major portion
(state-wide aggregate approximately 46% in recent years) of their operating
moneys from State subsidies, but are dependent on local property taxes, and in
123 districts (as of June 8, 1999) from voter-authorized income taxes, for
significant portions of their budgets. Litigation, similar to that in other
states, has



                                      -59-
<PAGE>   282

been pending questioning the constitutionality of Ohio's system of school
funding. The Ohio Supreme Court has concluded that aspects of the system
(including basic operating assistance and the loan program referred to below)
are unconstitutional, and ordered the State to provide for and fund a system
complying with the Ohio Constitution, staying its order to permit time for
responsive corrective actions. After a further hearing, the trial court has
decided that steps taken to date by the State to enhance school funding have not
met the requirements of the Supreme Court decision; the State has filed a notice
of appeal with the Supreme Court, and that Court has issued a stay, pending
appeal, of the implementation of the trial court's order. A small number of the
State's 612 local school districts have in any year required special assistance
to avoid year-end deficits. A program has provided for school district cash need
borrowing directly from commercial lenders, with diversion of State subsidy
distributions to repayment if needed. Recent borrowings under this program
totaled $71.1 million for 29 districts in FY 1995 (including $29.5 million for
one), $87.2 million for 20 districts in FY 1996 (including $42.1 million for
one), $113.2 million for 12 districts in FY 1997 (including $90 million to one
for restructuring its prior loans), and $23.4 million for 10 districts in FY
1998.

                  Ohio's 943 incorporated cities and villages rely primarily on
property and municipal income taxes for their operations. With other
subdivisions, they also receive local government support and property tax relief
moneys distributed by the State.

                  For those few municipalities and school districts that on
occasion have faced significant financial problems, there are statutory
procedures for a joint State/local commission to monitor the fiscal affairs and
for development of a financial plan to eliminate deficits and cure any defaults.
(Similar procedures have recently been extended to counties and townships.)
Since inception for municipalities in 1979, these "fiscal emergency" procedures
have been applied to 26 cities and villages; for 20 of them the fiscal situation
was resolved and the procedures terminated (one city is in preliminary "fiscal
watch" status). As of June 8, 1999, a school district "fiscal emergency"
provision was applied to nine districts, and ten were on preliminary "fiscal
watch" status.

                  At present the State itself does not levy ad valorem taxes on
real or tangible personal property. Those taxes are levied by political
subdivisions and other local taxing districts. The Constitution has since 1934
limited to 1% of true value in money the amount of the aggregate levy (including
a levy for unvoted general obligations) of property taxes by all overlapping
subdivisions, without a vote of the electors or a municipal charter provision,
and statutes limit the amount of that aggregate levy to 10 mills per $1 of
assessed valuation (commonly referred to as the "ten-mill limitation"). Voted
general obligations of subdivisions are payable from property taxes that are
unlimited as to amount or rate.

Special Risk Considerations Regarding Investment in Pennsylvania Securities

                  Potential shareholders should consider the fact that the
Pennsylvania Municipal Bond Fund's portfolio consists primarily of securities
issued by the Commonwealth of Pennsylvania (the "Commonwealth"), its
municipalities and authorities and should realize that the Fund's performance is
closely tied to general economic conditions within the Commonwealth as a



                                      -60-
<PAGE>   283

whole and to economic conditions within particular industries and geographic
areas located within the Commonwealth.

                  Although the General Fund of the Commonwealth (the principal
operating fund of the Commonwealth) experienced deficits in fiscal 1990 and
1991, tax increases and spending decreases have resulted in surpluses the last
six years; as of June 30, 1998, the General Fund had a surplus of $1,364.9
million.

                  Pennsylvania's economy historically has been dependent upon
heavy industry, but has diversified recently into various services, particularly
into medical and health services, education and financial services. Agricultural
industries continue to be an important part of the economy, including not only
the production of diversified food and livestock products, but substantial
economic activity in agribusiness and food-related industries. Service
industries currently employ the greatest share of non-agricultural workers,
followed by the categories of trade and manufacturing. Future economic
difficulties in any of these industries could have an adverse impact on the
finances of the Commonwealth or its municipalities, and could adversely affect
the market value of the Bonds in the Pennsylvania Trust or the ability of the
respective obligors to make payments of interest and principal due on such
Bonds.

                  Certain litigation is pending against the Commonwealth that
could adversely affect the ability of the Commonwealth to pay debt service on
its obligations including as of June 1, 1999, suits relating to the following
matters: (i) In February 1999, a taxpayer filed a petition for review in the
Commonwealth Court of Pennsylvania asking the court to declare that Chapter 5
(relating to Sports Facilities Financing) of the Capital Facilities Debt
Enabling Act is in violation of the Pennsylvania Constitution. Commonwealth
Court denied the taxpayer's motion for a preliminary injunction and the Supreme
Court denied an appeal of such denial. The respondents have filed preliminary
objections in the nature of a demurrer, requesting the Court dismiss the case
with prejudice. Oral arguments before the Commonwealth Court regarding the
preliminary objections were scheduled for May 19, 1999, (ii) The American Civil
Liberties Union ("ACLU") filed suit in federal court demanding additional
funding for child welfare services; the Commonwealth settled a similar suit in
the Commonwealth Court of Pennsylvania and is seeking the dismissal of the
federal suit, among other things, because of that settlement. After its earlier
denial of class certification was reversed by the Third Circuit Court of
Appeals, the district court granted class certification to the ACLU, and the
parties are proceeding with discovery. In July 1998, a settlement agreement was
reached with the City of Philadelphia. The Commonwealth has agreed to pay
$100,000 to settle plaintiffs' $1.4 million claim for attorney's fees and to
take other actions in exchange for a full and final release and dismissal of the
case against the Commonwealth parties. The settlement was approved by the
district court on February 1, 1999, and the case was dismissed; (iii) In 1987,
the Supreme Court of Pennsylvania held the statutory scheme for county funding
of the judicial system to be in conflict with the constitution of the
Commonwealth, but it stayed judgment pending enactment by the legislature of
funding consistent with the opinion, and the legislature has yet to consider
legislation implementing the judgment. In 1992, a new action in mandamus was
filed seeking to compel the Commonwealth to comply with the original decision.
The Court issued a writ in mandamus and appointed a special master in 1996 to
submit a plan for implementation, which it intended to require by January 1,
1998. In January 1997, the Court

                                      -61-
<PAGE>   284

established a committee, consisting of the special master and representatives of
the Executive and Legislative branches, to develop an implementation plan; an
implementation plan was filed in July 1997. In April 1998 the General Assembly
appropriated approximately $12 million for the funding of county court
administrator, under the implementation plan. However, no legislation has been
approved for the payment of Commonwealth compensation county court
administrators. In May 1998, an action was filed by the Administrative Governing
Board of the First Judicial District claiming the city government has failed to
provide adequate Funds for the Operation of the courts of the First Judicial
District. In November 1998, the First Judicial District Governing Board filed
with the Supreme Court a renewed motion for entry of an order providing
emergency relief, which requests the City of Philadelphia to provide funds to
the First Judicial District Courts, in order to maintain necessary judicial
operations throughout the end of the fiscal year. Although the Supreme Court
issued no order, the City is apparently continuing its funding of the courts;
(iv) Litigation was filed in both state and federal court by an association of
rural and small schools and several individual school districts and parents
challenging the constitutionality of the Commonwealth's system for funding local
school districts -- the federal case has been stayed pending the resolution of
the state case; a trial in the state case commenced in January 1997 and has
recessed; no briefing schedule or date for oral argument has yet been set; On
July 9, 1998 the state court issued an opinion dismissing the petitioners' claim
in its entirety. On July 20, 1998 the petitioner filed a timely motion for
post-trial relief, taking exception to the state court's findings of fact and
conclusions of law. The Supreme Court, after assuming jurisdiction in the case
directed that all parties submit briefs on all issues presented in the
petitioners' motion for post-trial relief; and (v) In 1995, the Commonwealth,
the Governor of Pennsylvania, the City of Philadelphia and the Mayor of
Philadelphia were joined as additional respondents in an enforcement action
commenced in Commonwealth Court in 1973 by the Pennsylvania Human Relations
Commission against the School District of Philadelphia pursuant to the
Pennsylvania Human Relations Act. The Commonwealth and the City were joined to
determine their liability, if any, to pay additional costs necessary to remedy
segregation-related conditions found to exist in Philadelphia public schools. In
January 1997, the Pennsylvania Supreme Court ordered the parties to brief
certain issues. The Supreme Court heard oral argument on the issues in February
1998 but no decision has been issued, (vi) In February 1997, five residents of
the City of Philadelphia, joined by the City, the School District and others,
filed a civil action in the Commonwealth Court for declaratory judgment against
the Commonwealth and certain Commonwealth officers and officials that the
defendants had failed to provide an adequate quality of education in
Philadelphia, as required by the Pennsylvania Constitution. In March 1998, the
Commonwealth Court dismissed the case on the grounds that the issues prescribed
are not justifiable. An appeal to the Supreme Court of Pennsylvania is pending,
(vii) In April 1995, the Commonwealth reached a settlement agreement with
Fidelity Bank and certain other banks with respect to the constitutional
validity of the Amended Bank Shares Act and related legislation; although this
settlement agreement did not require expenditure of Commonwealth funds, the
petitions of other banks are currently pending with the Commonwealth Court; In
January 1998 a panel of the Commonwealth Court ruled in favor of the
Commonwealth, finding no constitutional violation. Royal Bank filed exceptions,
which the Commonwealth Court EN BANC denied. Royal Bank appealed to the Supreme
Court and briefing has been completed. The Court has not yet scheduled oral
arguments. (viii) Suit has been filed in state court against the State
Employees' Retirement Board claiming that the use of gender district actuarial
factors to compute benefits received before August 1, 1983 violates the
Pennsylvania

                                      -62-
<PAGE>   285

Constitution (gender-neutral factors have been used since August 1, 1983, the
date on which the U.S. Supreme Court held in ARIZONA GOVERNING COMMITTEE V.
NORRIS that the use of such factors violated the Federal Constitution); in 1996,
the Commonwealth Court heard oral argument EN BLANC, and in 1997 denied the
plaintiff's motion for judgement on the pleading. The case is currently in
discovery. (ix) In March 1997, Rite Aid of Pennsylvania, Inc. filed in the
United States District Court for the Eastern District of Pennsylvania, a civil
action against the Secretary of Public Welfare alleging that regulations
promulgated in October 1995 governing payment rates for prescription drugs and
related services provided to recipients of benefits under the Pennsylvania
Medical Assistance Program violated provisions of Title XIX of the Social
Security Act and regulations of the U.S. Department of Health and Human
Services, as well as provisions of State law and Federal constitutional due
process. In August 1998, the court declared that certain pharmacy reimbursement
rates were in violation of the Medicaid Act and enjoined the Secretary from
using these rates to reimburse for any prescription drugs and related services
provided to Medicaid recipients on and after October 1, 1998. The Secretary
filed motions for appeal and in March 1999, the U.S. Court of Appeals for the
Third Circuit reversed the district court's order and remanded the case for
further proceedings. The plaintiffs on April 5, 1999 filed an application for
rehearing. (x) On March 9, 1998 several residents of the City of Philadelphia
along with the School District of Philadelphia and others brought suit in the
United States District Court for the Eastern District of Pennsylvania against
the Governor, the Secretary of Education and others alleging that the defendants
are violating a regulation of the U.S. Department of Education promulgated under
Title VI of the Civil Rights Act of 1964 in that the Commonwealth's system for
funding public schools has the effect of discrimination on the basis of race. On
November 18, 1998, the district court dismissed the action with prejudice. An
appeal by the plaintiffs was filed and the parties are awaiting the scheduling
of oral argument.

                  Although there can be no assurance that such conditions will
continue, the Commonwealth's general obligation bonds are currently rated AA by
S&P and A3 and A1 by Moody's and Philadelphia's and Pittsburgh's general
obligation bonds are currently rated BBB and BBB, respectively, by S&P and Baa2
and Baa1, respectively, by Moody's.

                  The City of Philadelphia (the "City") experienced a series of
General Fund deficits for fiscal years 1988 through 1992 and, while its general
financial situation has improved, the City is still seeking a long-term solution
for its economic difficulties. The audited balance of the City's General Fund as
of June 30, 1998 was a surplus of $169.2 million.

                  In recent years an authority of the Commonwealth, the
Pennsylvania Intergovernmental Cooperation Authority ("PICA"), has issued
approximately $1.76 billion of special revenue bonds on behalf of the City to
cover budget shortfalls, to eliminate projected deficits and to fund capital
spending. As one of the conditions of issuing bonds on behalf of the City, PICA
exercises oversight of the City's finances. The City is currently operating
under a five year plan approved by PICA in 1996. PICA's power to issue further
bonds to finance capital projects expired on December 31, 1994. PICA's authority
to issue bonds to finance cash flow deficits expired on December 31, 1996, but
its authority to refund existing debt will not expire. PICA had approximately
$1.1 billion in special revenue bonds outstanding as of April 15, 1999.

                  SPECIAL CONSIDERATIONS REGARDING INVESTMENT IN MICHIGAN
MUNICIPAL SECURITIES. The following information is drawn from various Michigan
governmental publications, particularly the Governor's Executive Budget for
fiscal year 1999-2000, and from official statements relating to securities
offerings of the State and its political subdivisions. While the Trust has not
independently verified such information, it has no reason to believe that it is
not correct in all material respects.

                  The State of Michigan's economy is principally dependent on
manufacturing (particularly automobiles, office equipment and other durable
goods), tourism and agriculture, and historically has been highly cyclical.

                  Total State wage and salary employment is estimated to have
grown by 1.9% in 1998. The rate of unemployment is estimated to have been 3.8%
in 1998, below the national average for the fifth consecutive year. Personal
income grew at an estimated 5.1% annual rate in 1998, up from the 4.6% growth
reported for 1997.

                  During the past five years, improvements in the Michigan
economy have resulted in increased revenue collections which, together with
restraints on the expenditure side of the budget, have resulted in State General
Fund budget surpluses, most of which were transferred to the State's
Counter-Cyclical Budget and Economic Stabilization Fund. The balance of that
Fund as of September 30, 1998 is estimated to have been in excess of $1.1
billion.

                  The Michigan Constitution limits the amount of total State
revenues that can be raised from taxes and certain other sources. State revenues
(excluding federal aid and revenues for payment of principal and interest on
general obligation bonds) in any fiscal year are limited to a fixed percentage
of State personal income in the prior calendar year or the average of the prior
three calendar years, whichever is greater, and this fixed percentage equals the
percentage of the 1978-79 fiscal year state government revenues to total
calendar year 1977 State personal income (which was 9.49%).

                  The Michigan Constitution also provides that the proportion of
State spending paid to all units of local government to total State spending may
not be reduced below the proportion in effect in the 1978-79 fiscal year. The
State originally determined that portion to be 41.6%. If such spending does not
meet the required level in a given year, an additional appropriation for local
governmental units is required by the following fiscal year; which means the
year following the determinations of the shortfall, according to an opinion
issued by the State's Attorney General. Spending for local units met this
requirement for fiscal years 1986-87 through 1991-92. As the result of
litigation, the State agreed to reclassify certain expenditures, beginning with
fiscal year 1992-93, and has recalculated the required percentage of spending
paid to local government units to be 48.97%.

                  The State has issued and has outstanding general obligation
full faith and credit bonds for Water Resources, Environmental Protection
Program, Recreation Program and School Loan purposes. As of September 30, 1998,
the State had approximately $874 million of general obligation bonds
outstanding.



                                      -64-
<PAGE>   287

                  The State may issue notes or bonds without voter approval for
the purposes of making loans to school districts. The proceeds of such notes or
bonds are deposited in the School Bond Loan Fund maintained by the State
Treasurer and used to make loans to school districts for payment of debt on
qualified general obligation bonds issued by local school districts.

                  The State is a party to various legal proceedings seeking
damages or injunctive or other relief. In addition to routine litigation,
certain of these proceedings could, if unfavorably resolved from the point of
view of the State, substantially affect State programs or finances. As of early
1998, these lawsuits involved programs generally in the areas of corrections,
tax collection, commerce, and proceedings involving budgetary reductions to
school districts and governmental units, and court funding. Notable among these
legal proceedings are lawsuits brought by a number of school districts
challenging the constitutionality of certain state-mandated special education
services without corresponding state funding.

                  The State Constitution limits the extent to which
municipalities or political subdivisions may levy taxes upon real and personal
property through a process that regulates assessments.

                  On March 15, 1994, Michigan voters approved a property tax and
school finance reform measure commonly known as Proposal A. Under Proposal A, as
approved, effective May 1, 1994, the State sales and use tax increased from 4%
to 6%, the State income tax decreased from 4.6% to 4.4%, the cigarette tax
increased from $.25 to $.75 per pack and an additional tax of 16% of the
wholesale price began to be imposed on certain other tobacco products. A .75%
real estate transfer tax became effective January 1, 1995. Beginning in 1994, a
state property tax of 6 mills began to be imposed on all real and personal
property currently subject to the general property tax. All local school boards
are authorized, with voter approval, to levy up to the lesser of 18 mills or the
number of mills levied in 1993 for school operating purposes on nonhomestead
property and nonqualified agricultural property. Proposal A contains additional
provisions regarding the ability of local school districts to levy taxes, as
well as a limit on assessment increases for each parcel of property, beginning
in 1995. Such increases for each parcel of property are limited to the lesser of
5% or the rate of inflation. When property is subsequently sold, its assessed
value will revert to the current assessment level of 50% of true cash value.
Under Proposal A, much of the additional revenue generated by the new taxes will
be dedicated to the State School Aid Fund.

                  Proposal A and its implementing legislation shifted
significant portions of the cost of local school operations from local school
districts to the State and raised additional State revenues to fund these
additional State expenses. These additional revenues will be included within the
State's constitutional revenue limitations and may impact the State's ability to
raise additional revenues in the future.

         A state economy during a recessionary cycle would also, as a separate
matter, adversely affect the capacity of users of facilities constructed or
acquired through the proceeds of private



                                      -65-
<PAGE>   288

activity bonds or other "revenue" securities to make periodic payments for the
use of those facilities.

OTHER TAX-EXEMPT INSTRUMENTS
- ----------------------------

                  Investments by the Ohio Tax Exempt Bond, Pennsylvania
Municipal Bond, National Tax Exempt Bond, Ohio Municipal Money Market,
Pennsylvania Tax Exempt Money Market and Tax Exempt Money Market Funds in
tax-exempt commercial paper will be limited to investments in obligations which
are rated at least A-2 or SP-2 by S&P, F-2 by Fitch or Prime-2, MIG-2 or VMIG-2
by Moody's at the time of investment or which are of equivalent quality as
determined by the Adviser. Investments in floating rate instruments will
normally involve industrial development or revenue bonds which provide that the
investing Fund can demand payment of the obligation at all times or at
stipulated dates on short notice (not to exceed 30 days) at par plus accrued
interest. A Fund must use the shorter of the period required before it is
entitled to prepayment under such obligations or the period remaining until the
next interest rate adjustment date for purposes of determining the maturity.
Such obligations are frequently secured by letters of credit or other credit
support arrangements provided by banks. The quality of the underlying credit or
of the bank, as the case may be, must, in the opinion of the Adviser be
equivalent to the commercial paper ratings stated above. The Adviser will
monitor the earning power, cash flow and liquidity ratios of the issuers of such
instruments and the ability of an issuer of a demand instrument to pay principal
and interest on demand. Other types of tax-exempt instruments may also be
purchased as long as they are of a quality equivalent to the bond or commercial
paper ratings stated above.


PORTFOLIO TURNOVER
- ------------------

                  The portfolio turnover rate for each Fund is calculated by
dividing the lesser of purchases or sales of portfolio securities for the year
by the monthly average value of the portfolio securities. The calculation
excludes U.S. Government securities and all securities whose maturities at the
time of acquisition were one year or less. Portfolio turnover may vary greatly
from year to year as well as within a particular year, and may also be affected
by cash requirements for redemptions of shares and by requirements which enable
the Trust to receive certain favorable tax treatment. Portfolio turnover will
not be a limiting factor in making decisions.

         The annual portfolio turnover rate for the International Equity, Small
Cap Value, Small Cap Growth, Equity Growth, Core Equity and Equity Income Funds
is not expected to exceed 100% under normal market conditions. Portfolio
turnover for the Tax Managed Equity and Equity Index Funds is not expected to
exceed 25% and 10%, respectively, under normal market conditions. The annual
portfolio turnover rate is not expected to exceed 100%, 200% and 100% for the
Mid Cap Growth, U.S. Government Income and Michigan Municipal Bond Funds,
respectively, under normal market conditions. The annual rate for the Total
Return Advantage, Intermediate Term Bond, GNMA, and Enhanced Income Funds is not
expected to exceed 100% under normal market conditions. Annual portfolio
turnover for the Treasury Plus Money Market Fund is expected to be zero percent
for regulatory purposes.

                             INVESTMENT LIMITATIONS

                  Each Fund is subject to a number of investment limitations.
The following investment limitations are matters of fundamental policy and may
not be changed with respect to a particular Fund without the affirmative vote of
the holders of a majority of the Fund's outstanding shares.

                  No Fund may:

                  1. Purchase any securities which would cause 25% or more of
the value of its total assets at the time of purchase to be invested in the
securities of one or more issuers conducting their principal business activities
in the same industry, provided that:

                       (a) there is no limitation with respect to obligations
                           issued or guaranteed by the U.S. government, any
                           state, territory or possession of the United States,
                           the District of Columbia or any of their authorities,
                           agencies, instrumentalities or political
                           subdivisions, and repurchase agreements secured by
                           such instruments;

                       (b) wholly-owned finance companies will be considered to
                           be in the industries of their parents if their
                           activities are primarily related to financing the
                           activities of the parents;

                       (c) utilities will be divided according to their
                           services, for example, gas, gas transmission,
                           electric and gas, electric, and telephone will each
                           be considered a separate industry;

                       (d) personal credit and business credit businesses will
                           be considered separate industries.

                  2. Make loans, except that the Fund may purchase and hold debt
instruments and enter into repurchase agreements in accordance with its
investment objective and policies and may lend portfolio securities in an amount
not exceeding one-third of its total assets.

                  3. Borrow money, issue senior securities or mortgage, pledge
or hypothecate its assets except to the extent permitted under the 1940 Act.

                  In addition, the National Tax Exempt Bond Fund may not
purchase securities of any one issuer, other than securities issued or
guaranteed by the U.S. government or its agencies or instrumentalities if,
immediately after such purchase, more than 5% of the value of the Fund's total
assets would be invested in such issuer or the Fund would hold more than 10% of
any class of securities of the issuer or more than 10% of the outstanding voting
securities of the issuer, except that up to 25% of the value of the Fund's total
assets may be invested without regard to such limitations.



                                      -67-
<PAGE>   290

                  The Equity, Balanced Allocation and Fixed Income Funds may not
purchase securities of any one issuer, other than securities issued or
guaranteed by the U.S. government or its agencies or instrumentalities or, in
the case of the International Equity Fund, securities issued or guaranteed by
any foreign government, if, immediately after such purchase, more than 5% of the
value of the Fund's total assets would be invested in such issuer or the Fund
would hold more than 10% of any class of securities of the issuer or more than
10% of the outstanding voting securities of the issuer, except that up to 25% of
the value of the Fund's total assets may be invested without regard to such
limitations.

                  For purposes of the above investment limitations, a security
is considered to be issued by the governmental entity (or entities) whose assets
and revenues back the security, or, with respect to a private activity bond that
is backed only by the assets and revenues of a nongovernmental user, a security
is considered to be issued by such nongovernmental user.

                  Except for the Funds' policy on illiquid securities and
borrowing, if a percentage limitation is satisfied at the time of investment, a
later increase or decrease in such percentage resulting from a change in the
value of a Fund's portfolio securities will not constitute a violation of such
limitation for purposes of the 1940 Act.

                  Opinions relating to the validity of Municipal Securities and
to the exemption of interest thereon from federal and state income taxes are
rendered by qualified legal counsel to the respective issuers at the time of
issuance. Neither the Funds nor their adviser will review the proceedings
relating to the issuance of Municipal Securities or the basis for such opinions.

                  In addition to the investment limitations disclosed above, the
Funds are subject to the following investment limitations which may be changed
with respect to a particular Fund only by a vote of the holders of a majority of
such Fund's outstanding shares (as defined under "Miscellaneous" in the
Prospectus).

                  No Fund may:

                  1. Purchase or sell real estate, except that the Fund may
purchase securities of issuers which deal in real estate and may purchase
securities which are secured by interests in real estate.

                  2. Invest in commodities, except that as consistent with its
investment objective and policies the Fund may: (a) purchase and sell options,
forward contracts, futures contracts, including without limitation, those
relating to indices; (b) purchase and sell options on futures contracts or
indices; (c) purchase publicly traded securities of companies engaging in whole
or in part in such activities. For purposes of this investment limitation,
"Commodities" includes Commodity Contracts.

                  3. Act as an underwriter of securities within the meaning of
the Securities Act of 1933 except insofar as the Fund might be deemed to be an
underwriter upon the disposition of portfolio securities acquired within the
limitation on purchases of illiquid



                                      -68-
<PAGE>   291

securities and except to the extent that the purchase of obligations directly
from the issuer thereof in accordance with its investment objective, policies
and limitations may be deemed to be underwriting.

                  In addition, the Funds are subject to the following
non-fundamental limitations, which may be changed without the vote of
shareholders:

                  No Fund may:

                  1. Acquire any other investment company or investment company
security except in connection with a merger, consolidation, reorganization or
acquisition of assets or where otherwise permitted under the 1940 Act.

                  2. Write or sell put options, call options, straddles,
spreads, or any combination thereof, except as consistent with the Fund's
investment objective and policies for transactions in options on securities or
indices of securities, futures contracts and options on futures contracts and in
similar investments.

                  3. Purchase securities on margin, make short sales of
securities or maintain a short position, except that, as consistent with a
Fund's investment objective and policies, (a) this investment limitation shall
not apply to the Fund's transactions in futures contracts and related options,
options on securities or indices of securities and similar instruments, and (b)
it may obtain short-term credit as may be necessary for the clearance of
purchases and sales of portfolio securities.

                  4. Purchase securities of companies for the purpose of
exercising control.

                  5. Invest more than 15% (10% in the case of the Money Market
Funds) of its net assets in illiquid securities.

                  6. Purchase securities while its outstanding borrowings
(including reverse repurchase agreements) are in excess of 5% of its total
assets. Securities held in escrow or in separate accounts in connection with a
Fund's investment practices described in its Prospectus or Statement of
Additional Information are not deemed to be pledged for purposes of this
limitation.

                  With respect to each of the Ohio Tax Exempt and Pennsylvania
Municipal Bond Funds, at the end of each quarter of its taxable year, (i) at
least 50% of the market value of its total assets will be invested in cash, U.S.
Government securities, securities of other regulated investment companies and
other securities, with such other securities of any one issuer limited for the
purposes of this calculation to an amount not greater than 5% of the value of
its total assets and 10% of the outstanding voting securities of such issuer,
and (ii) not more than 25% of the value of its total assets will be invested in
the securities of any one issuer (other than U.S. Government securities or the
securities of other regulated investment companies).


                                      -69-
<PAGE>   292


                                 NET ASSET VALUE
                                 ---------------

                  The Trust uses the amortized cost method to value shares in
the Money Market Funds. Pursuant to this method, a security is valued at its
cost initially and thereafter a constant amortization to maturity of any
discount or premium is assumed, regardless of the impact of fluctuating interest
rates on the market value of the security. Where it is not appropriate to value
a security by the amortized cost method, the security will be valued either by
market quotations, or by fair value as determined by the Board of Trustees.
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 each respective Fund would receive if it sold the security. The value of
the portfolio securities held by each respective Fund will vary inversely to
changes in prevailing interest rates. Thus, if interest rates have increased
from the time a security was purchased, such security, if sold, might be sold at
a price less than its cost. Similarly, if interest rates have declined from the
time a security was purchased, such security, if sold, might be sold at a price
greater than its purchase cost. In either instance, if the security is held to
maturity, no gain or loss will be realized.

                  The Money Market Funds invest only in high-quality instruments
and maintains a dollar-weighted average portfolio maturity appropriate to its
objective of maintaining a stable net asset value per share, provided that a
Fund will neither purchase any security deemed to have a remaining maturity of
more than 397 calendar days within the meaning of the 1940 Act nor maintain a
dollar-weighted average portfolio maturity which exceeds 90 days. The Trust's
Board of Trustees has established procedures pursuant to rules promulgated by
the SEC, that are intended to help stabilize the net asset value per share of
each Fund for purposes of sales and redemptions at $1.00. These procedures
include review by the Board of Trustees, at such intervals as it deems
appropriate, to determine the extent, if any, to which the net asset value per
share of each Fund calculated by using available market quotations deviates from
$1.00 per share. In the event such deviation exceeds one-half of one percent,
the Board of Trustees will promptly consider what action, if any, should be
initiated. If the Board of Trustees believes that the extent of any deviation
from a Fund's $1.00 amortized cost price per share may result in material
dilution or other unfair results to investors or existing shareholders, it has
agreed to take such steps as it considers appropriate to eliminate or reduce, to
the extent reasonably practicable, any such dilution or unfair results. These
steps may include selling portfolio instruments prior to maturity; shortening
the average portfolio maturity; withholding or reducing dividends; redeeming
shares in kind; reducing the number of a Fund's outstanding shares without
monetary consideration; or utilizing a net asset value per share determined by
using available market quotations.


                                    DIVIDENDS
                                    ---------

                  As stated, the Trust uses its best efforts to maintain the net
asset value per share of Money Market Funds at $1.00. As a result of a
significant expense or realized or unrealized loss incurred by the Funds, it is
possible that a Fund's net asset value per share may fall below $1.00. Should
the Trust incur or anticipate any unusual or unexpected significant expense or
loss which would affect disproportionately the income of a Fund for a particular
period, the Board of Trustees



                                      -70-
<PAGE>   293

would at that time consider whether to adhere to the present dividend policy
with respect to the Funds or to revise it in order to ameliorate to the extent
possible the disproportionate effect of such expense or loss on the income of
the Fund experiencing such effect. Such expense or loss may result in a
shareholder's receiving no dividends for the period in which he or she holds
shares of a Fund and/or in his or her receiving upon redemption a price per
share lower than the price he or she paid.


                  ADDITIONAL PURCHASE AND REDEMPTION INFORMATION
                  ----------------------------------------------

                  Shares in the Trust are sold on a continuous basis by SEI
Investments Distribution Co. (the "Distributor"), which has agreed to use
appropriate efforts to solicit all purchase orders. The issuance of shares is
recorded on the books of the Trust. To change the commercial bank or account
designated to receive redemption proceeds, a written request must be sent to an
investor's financial institution at its principal office or directly to the Fund
at P.O. Box 8421, Boston, MA 02266-8421. Such requests must be signed by each
shareholder, with each signature guaranteed by a U.S. commercial bank or trust
company or by a member firm of a national securities exchange. Guarantees must
be signed by an authorized signatory and "Signature Guaranteed" must appear with
the signature. An investor's financial institution may request further
documentation from corporations, executors, administrators, trustees or
guardians, and will accept other suitable verification arrangements from foreign
investors, such as consular verification.

                  The Trust may suspend the right of redemption or postpone the
date of payment for shares for more than seven days during any period when (a)
trading on the Exchange is restricted by applicable rules and regulations of the
SEC; (b) the Exchange is closed for other than customary weekend and holiday
closings; (c) the SEC has by order permitted such suspension; or (d) an
emergency exists as determined by the SEC.

                  As described in the Prospectus, I (formerly, Institutional)
shares of the Fund are sold to certain qualified investors at their net asset
value without a sales charge. A (formerly, Retail) shares of the Fund are sold
to public investors at the public offering price based on the Fund's net asset
value plus a front-end load or sales charge as described in the Prospectus. B
shares of the Money Market and Tax Exempt Funds are available only to the
holders of B shares of another Fund who wish to exchange their B shares of such
other Fund for B shares of the Money Market and/or Tax Exempt Funds. B shares of
the Fund are sold to public investors at net asset value but are subject to a
contingent deferred sales charge which is payable upon redemption of such shares
as described in the Prospectus. There is no sales load or contingent deferred
sales charge imposed for shares acquired through the reinvestment of dividends
or distributions on such shares.

         *The Class A Shares of the Equity Index Fund commenced operations on
October 15, 1998. The figure shown represents sales loads paid since this date.

Government Income, Michigan Municipal Bond and Treasury Plus Money Market Funds
have not commenced operations.

                  Automatic investment programs such as the monthly savings
program ("Program") described in the Prospectus offered by the Funds permit an
investor to use "dollar cost averaging" in making investments. Under this
Program, an agreed upon fixed dollar amount is invested in Fund shares at
predetermined intervals. This may help investors to reduce their average cost
per share because the Program results in more shares being purchased during
periods of lower share prices and fewer shares during periods of higher share
prices. In order to be effective, dollar cost averaging should usually be
followed on a sustained, consistent basis. Investors should be aware, however,
that dollar cost averaging results in purchases of shares regardless of their
price on the day of investment or market trends and does not ensure a profit,
protect against losses in a declining market, or prevent a loss if an investor
ultimately redeems his or her shares at a price which is lower than their
purchase price. An investor may want to consider his or her financial ability to
continue purchases through periods of low price levels. From time to time, in
advertisements, sales literature, communications to shareholders and other
materials ("Materials"), the Trust may illustrate the effects of dollar cost
averaging through use of or comparison to an index such as the S&P 500 Index or
Lehman Intermediate Government Index.

EXCHANGE PRIVILEGE
- ------------------

                  Investors may exchange all or part of their A or B shares as
described in the Prospectus. Any rights an Investor may have (or have waived) to
reduce the sales load applicable to an exchange, as may be provided in a Fund
Prospectus, will apply in connection with any such exchange. The exchange
privilege may be modified or terminated at any time upon 60 days' notice to
shareholders.

                  By use of the exchange privilege, the Investor authorizes the
Transfer Agent's financial institution or his or her financial institution to
act on telephonic, website or written instructions from any person representing
himself or herself to be the shareholder and believed by the Transfer Agent or
the financial institution to be genuine. The Investor or his or her financial
institution must notify the Transfer Agent of his or her prior ownership of A or
B shares and account number. The Transfer Agent's records of such instructions
are binding.


                              DESCRIPTION OF SHARES
                              ---------------------

                  The Trust is a Massachusetts business trust. The Trust's
Declaration of Trust authorizes the Board of Trustees to issue an unlimited
number of shares of beneficial interest and to classify or reclassify any
unissued shares of the Trust into one or more additional classes or series by

conversion or other rights, voting powers, restrictions, limitations as to
dividends, qualifications, and terms and conditions of redemption. Pursuant to
such authority, the Board of Trustees has authorized the issuance of the classes

Series 1 and Class L-Special Series 2); Ohio Municipal Money Market Fund (Class
BB and Class BB - Special Series 1); Pennsylvania Tax Exempt Money Market Fund
(Class Q and Class Q - Special Series 1), Tax Exempt Money Market Fund (Class D,
Class D - Special Series 1 and Class D - Special Series 2), Money Market Fund
(Class A, Class A -Special Series 1 and Class A - Special Series 2), Government

Market Fund (Class C and Class C - Special Series 1), Mid Cap Growth Fund (Class

Special Series 1 and Class HH Special Series 2) and the Treasury Plus Money
Market Fund (Class CC and Class CC - Special Series 1), as described in this
Statement of Additional Information and the related Prospectus.

                  Shares have no preemptive rights and only such conversion or
exchange rights as the Board of Trustees may grant in its discretion. When
issued for payment as described in the Prospectus, the Trust's shares will be
fully paid and non-assessable. In the event of a liquidation or dissolution of
the Trust or an individual Fund, shareholders of a Fund are entitled to receive
the assets available for distribution belonging to the particular Fund, and a
proportionate distribution, based upon the relative asset values of the
respective Funds, of any general assets of the Trust not belonging to any
particular Fund which are available for distribution.

                  Rule 18f-2 under the 1940 Act provides that any matter
required by the 1940 Act, applicable state law, or otherwise, to be submitted to
the holders of the outstanding voting securities of an investment company such
as the Trust shall not be deemed to have been effectively acted upon unless
approved by the holders of a majority of the outstanding shares of each
investment fund affected by such matter. Rule 18f-2 further provides that an
investment fund is affected by a matter unless the interests of each fund in the
matter are substantially identical or the matter does not affect any interest of
the fund. Under the Rule, the approval of an investment advisory agreement or
any change in a fundamental investment policy would be effectively acted upon
with respect to an investment fund only if approved by a majority of the
outstanding shares of such fund. However, the Rule also provides that the
ratification of the appointment of independent public accountants, the approval
of principal underwriting contracts, and the election of trustees may be
effectively acted upon by shareholders of the Trust voting together in the
aggregate without regard to a particular fund. In addition, shareholders of each
class in a particular investment fund have equal voting rights except that only
I and A shares of an investment fund will be entitled to vote on matters
submitted to a vote of shareholders (if any) relating to a distribution plan for
such shares, and only B shares of a Fund will be entitled to vote on matters
relating to a distribution plan with respect to B shares.

                  Although the following types of transactions are normally
subject to shareholder approval, the Board of Trustees may, under certain
limited circumstances, (a) sell and convey the assets of an investment fund to
another management investment company for consideration which may include
securities issued by the purchaser and, in connection therewith, to cause all
outstanding shares of such fund involved to be redeemed at a price which is
equal to their net asset value and which may be paid in cash or by distribution
of the securities or other consideration



                                      -81-
<PAGE>   304

received from the sale and conveyance; (b) sell and convert an investment fund's
assets into money and, in connection therewith, to cause all outstanding shares
of such fund involved to be redeemed at their net asset value; or (c) combine
the assets belonging to an investment fund with the assets belonging to another
investment fund of the Trust, if the Board of Trustees reasonably determines
that such combination will not have a material adverse effect on shareholders of
any fund participating in such combination, and, in connection therewith, to
cause all outstanding shares of any fund to be redeemed at their net asset value
or converted into shares of another class of the Trust shares at net asset
value. In the event that shares are redeemed in cash at their net asset value, a
shareholder may receive in payment for such shares an amount that is more or
less than his or her original investment due to changes in the market prices of
the fund's securities. The exercise of such authority by the Board of Trustees
will be subject to the provisions of the 1940 Act, and the Board of Trustees
will not take any action described in this paragraph unless the proposed action
has been disclosed in writing to the fund's shareholders at least 30 days prior
thereto.


                     ADDITIONAL INFORMATION CONCERNING TAXES
                     ---------------------------------------

                  The following summarizes certain additional tax considerations
generally affecting the Trust and its shareholders that are not described in the
Prospectus. No attempt is made to present a detailed explanation of the tax
treatment of the Trust or its shareholders or possible legislative changes, and
the discussion here and in the Prospectus is not intended as a substitute for
careful tax planning. Potential investors should consult their tax advisers with
specific reference to their own tax situation.

                  Each Fund of the Trust will be treated as a separate corporate
entity under the Code and intends to qualify as a regulated investment company.
In order to qualify for tax treatment as a regulated investment company under
the Code, the Fund must satisfy, in addition to the distribution requirement
described in the Prospectus, certain requirements with respect to the source of
its income during a taxable year. At least 90% of the gross income of the Fund
must be derived from dividends, interest, payments with respect to securities
loans, gains from the sale or other disposition of stocks, securities or foreign
currencies, and other income (including but not limited to gains from options,
futures, or forward contracts) derived with respect to the Fund's business of
investing in such stock, securities or currencies. The Treasury Department may
by regulation exclude from qualifying income foreign currency gains which are
not directly related to the Fund's principal business of investing in stock or
securities, or options and futures with respect to stock or securities. Any
income derived by the Fund from a partnership or trust is treated as derived
with respect to the Fund's business of investing in stock, securities or
currencies only to the extent that such income is attributable to items of
income which would have been qualifying income if realized by the Fund in the
same manner as by the partnership or trust.

                  A 4% non-deductible excise tax is imposed on regulated
investment companies that fail to currently distribute an amount equal to
specified percentages of their ordinary taxable income and capital gain net
income (excess of capital gains over capital losses). Each Fund intends to make
sufficient distributions or deemed distributions of its ordinary taxable income
and capital gain net income each calendar year to avoid liability for this
excise tax.



                                      -82-
<PAGE>   305

                  If for any taxable year the Fund does not qualify for federal
tax treatment as a regulated investment company, all of the Fund's taxable
income will be subject to federal income tax at regular corporate rates without
any deduction for distributions to its shareholders. In such event, dividend
distributions (including amounts derived from interest on Municipal Securities)
would be taxable as ordinary income to the Fund's shareholders to the extent of
the Fund's current and accumulated earnings and profits, and would be eligible
for the dividends received deduction for corporations.

                  A Fund may be required in certain cases to withhold and remit
to the U.S. Treasury 31% of taxable dividends or gross proceeds realized upon
sale paid to shareholders who have failed to provide a correct tax
identification number in the manner required, or who are subject to withholding
by the Internal Revenue Service for failure to properly include on their return
payments of taxable interest or dividends, or who have failed to certify to the
Fund that they are not subject to backup withholding when required to do so or
that they are "exempt recipients."

                  The tax principles applicable to transactions in financial
instruments and futures contacts and options that may be engaged in by a Fund,
and investments in passive foreign investment companies ("PFICs"), are complex
and, in some cases, uncertain. Such transactions and investments may cause a
Fund to recognize taxable income prior to the receipt of cash, thereby requiring
the Fund to liquidate other positions, or to borrow money, so as to make
sufficient distributions to shareholders to avoid corporate-level tax. Moreover,
some or all of the taxable income recognized may be ordinary income or
short-term capital gain, so that the distributions may be taxable to
shareholders as ordinary income.

                  In addition, in the case of any shares of a PFIC in which a
Fund invests, the Fund may be liable for corporate-level tax on any ultimate
gain or distributions on the shares if the Fund fails to make an election to
recognize income annually during the period of its ownership of the shares.

ADDITIONAL TAX INFORMATION CONCERNING THE OHIO TAX EXEMPT BOND, PENNSYLVANIA
- ----------------------------------------------------------------------------
MUNICIPAL BOND, NATIONAL TAX EXEMPT BOND AND TAX EXEMPT MONEY MARKET FUNDS
- --------------------------------------------------------------------------

                  As described above and in the Prospectus, the Ohio Tax Exempt
Bond, Pennsylvania Municipal Bond, National Tax Exempt Bond, Ohio Municipal
Money Market, Pennsylvania Tax Exempt Money Market and Tax Exempt Money Market
Funds are designed to provide investors with tax-exempt interest income. The
Funds are not intended to constitute a balanced investment program and are not
designed for investors seeking capital appreciation or maximum tax-exempt income
irrespective of fluctuations in principal. Shares of the Funds would not be
suitable for tax-exempt institutions and may not be suitable for retirement
plans qualified under Section 401 of the Code, H.R. 10 plans and IRAs since such
plans and accounts are generally tax-exempt and, therefore, would not gain any
additional benefit from the Funds' dividends being tax-exempt.

                  The policy of the Funds is to pay each year as federal
exempt-interest



                                      -83-
<PAGE>   306

dividends substantially all the Funds' Municipal Securities interest income net
of certain deductions. In order for the Funds to pay federal exempt-interest
dividends with respect to any taxable year, at the close of each taxable quarter
at least 50% of the aggregate value of their respective portfolios must consist
of tax-exempt obligations. An exempt-interest dividend is any dividend or part
thereof (other than a capital gain dividend) paid by a Fund and designated as an
exempt-interest dividend in a written notice mailed to shareholders not later
than 60 days after the close of the Fund's taxable year. However, the aggregate
amount of dividends so designated by the Funds cannot exceed the excess of the
amount of interest exempt from tax under Section 103 of the Code received by the
Funds during the taxable year over any amounts disallowed as deductions under
Sections 265 and 171(a)(2) of the Code. The percentage of total dividends paid
by the Funds with respect to any taxable year which qualifies as federal
exempt-interest dividends will be the same for all shareholders receiving
dividends from the Funds with respect to such year.

                  Shareholders are advised to consult their tax advisers with
respect to whether exempt-interest dividends would retain the exclusion under
Section 103(a) if the shareholder would be treated as a "substantial user" or a
"related person" to such user with respect to facilities financed through any of
the tax-exempt obligations held by the Funds. A "substantial user" is defined
under U.S. Treasury Regulations to include a non-exempt person who regularly
uses a part of such facilities in his or her trade or business and whose gross
revenues derived with respect to the facilities financed by the issuance of
bonds are more than 5% of the total revenues derived by all users of such
facilities, or who occupies more than 5% of the usable area of such facilities
or for whom such facilities or a part thereof were specifically constructed,
reconstructed or acquired. A "related person" includes certain related natural
persons, affiliated corporations, partners and partnerships, and S corporations
and their shareholders.

ADDITIONAL TAX INFORMATION CONCERNING THE MICHIGAN MUNICIPAL BOND FUND
- ----------------------------------------------------------------------

         As indicated in the Prospectus, the Michigan Municipal Bond Fund is
designed to provide shareholders with current tax-exempt interest income. The
Fund is not intended to constitute a balanced investment program and is not
designed for investors seeking capital appreciation or maximum tax-exempt income
irrespective of fluctuations in principal. Shares of the Fund would not be
suitable for tax-exempt institutions and may not be suitable for retirement
plans qualified under Section 401 of the Code, H.R. 10 plans and individual
retirement accounts, since such plans and accounts are generally tax-exempt and,
therefore, would not gain any additional benefit from the Fund's dividends being
tax-exempt; furthermore, such dividends would be ultimately taxable to the
beneficiaries when distributed to them. In addition, the Fund may not be
appropriate investments for entities which are "substantial users," or "related
persons" thereof, of facilities financed by private activity bonds held by the
Fund. "Substantial user" is defined under U.S. Treasury Regulations to include a
non-exempt person who regularly uses a part of such facilities in his or her
trade or business and whose gross revenues derived with respect to the
facilities financed by the issuance of bonds represent more than 50% of the
total revenues derived by any users of such facilities, or who occupies more
than 5% of the usable area of such facilities or for whom such facilities or a
part thereof were specifically constructed,



                                      -84-
<PAGE>   307

reconstructed or acquired. "Related persons" include certain related natural
persons, affiliated corporations, a partnership and its partners and an S
Corporation and its shareholders.

         The percentage of total dividends paid by the Michigan Municipal Bond
Fund with respect to any taxable year which qualifies as federal exempt interest
dividends will be the same for all shareholders receiving dividends during such
year. In order for the Fund to pay exempt-interest dividends during any taxable
year, at the close of each fiscal quarter, at least 50% of the aggregate value
of the Fund must consist of exempt-interest obligations. In addition, the Fund
must distribute 90% of the aggregate exempt-interest income and 90% of the
investment company taxable income earned by it during the taxable year. After
the close of the Fund's taxable year, the Fund will notify each shareholder of
the portion of the dividends paid by the Fund to the shareholder with respect to
such taxable year which constitutes an exempt-interest dividend. However, the
aggregate amount of dividends as designated cannot exceed the excess of the
amount of interest exempt from tax under Section 103 of the Code received by the
Fund during the taxable year over any amounts disallowed as deductions under
Section 265 and 171(a)(2) of the Code.

         Although the Michigan Municipal Bond Fund expects to qualify as a
regulated investment company and to be relieved of all or substantially all
federal income taxes, depending upon the extent of its activities in states and
localities in which its offices are maintained, in which its agents or
independent contractors are located, or in which it is otherwise deemed to be
conducting business, the Michigan Municipal Bond Fund may be subject to the tax
laws of such states or localities. In addition, if for any taxable year the Fund
does not qualify for the special tax treatment afforded a regulated investment
company, all of its taxable income will be subject to federal tax at regular
corporate rates (without any deduction for distributions to its shareholders).
In such event, dividend distributions would be taxable to shareholders to the
extent of earnings and profits, and would be eligible for the dividends received
deduction for corporations.

         The foregoing is only a summary of some of the important federal tax
considerations generally affecting purchasers of shares of the Michigan
Municipal Bond Fund. No attempt has been made to present a detailed explanation
of the federal income tax treatment of the Fund or its shareholders or of
Michigan state income tax treatment of the Fund or its shareholders, and this
discussion is not intended as a substitute for careful tax planning. Accordingly
potential purchasers of shares of the Fund are urged to consult their own tax
advisers with specific reference to their own tax situation. In addition, the
foregoing discussion is based on tax laws and regulations which are in effect on
the date of this Statement of Additional Information; such laws and regulations
may be changed by legislative or administrative action.

ADDITIONAL TAX INFORMATION CONCERNING THE OHIO TAX EXEMPT BOND FUND
- -------------------------------------------------------------------

         The Ohio Tax Exempt Bond Fund is not subject to the Ohio personal
income or school district or municipal income taxes in Ohio. The Ohio Tax Exempt
Bond Fund is not subject to the Ohio corporation franchise tax or the Ohio
dealers in intangibles tax, provided that, if there is a sufficient nexus
between the State of Ohio and such entity that would enable the State to tax
such entity, the Fund timely files the annual report required by Section 5733.09
of the Ohio Revised Code. The Ohio Tax Commissioner has waived the annual filing
requirement for every tax year since 1990, the first year to which such
requirement applied.

                  Shareholders of the Fund otherwise subject to Ohio personal
income tax or municipal or school district income taxes in Ohio imposed on
individuals and estates will not be subject to such taxes on distributions with
respect to shares of the Fund ("Distributions") to the extent that such
Distributions are properly attributable to interest on or gain from the sale of
obligations issued by or an behalf of Ohio, political subdivisions thereof or
agencies or instrumentalities of Ohio or its political subdivisions (Ohio
Obligations).

                  Shareholders otherwise subject to the Ohio corporation
franchise tax will not be required to include Distributions in their tax base
for purposes of calculating the Ohio corporation franchise tax on the net income
basis to the extent that such distributions either (a) are properly attributable
to interest on or gain from the sale of Ohio Obligations, (b) represent
"exempt-interest dividends" for federal income tax purposes, or (c) are
described in both (a) and (b). Shares of the Fund will be included in a
Shareholder's tax base for purposes of computing the Ohio corporation franchise
tax on the net worth basis.

                  Distributions that consist of interest on obligations of the
United States or its territories or possessions or of any authority, commission,
or instrumentality of the United States that is exempt from state income taxes
under the laws of the United States (including obligations issued by the
governments of Puerto Rico, the Virgin Islands or Guam and their authorities or
municipalities) ("Territorial Obligations") are exempt from the Ohio personal
income tax, and municipal and school district income taxes in Ohio, and,
provided, in the case of Territorial Obligations, such interest is excluded from
gross income for federal income tax purposes, are excluded from the net income
base of the Ohio corporation franchise tax.

                  It is assumed for purposes of this discussion of State and
Local Taxes that the Fund will continue to qualify as a regulated investment
company under the Internal Revenue Code of 1986, as amended, and that at all
times at least 50% of the value of the total assets of the Fund consists of Ohio
Obligations or similar obligations of other states or their subdivisions.

*        The "Fund Complex" consists of Armada Funds, The Parkstone Group of
         Funds and The Parkstone Advantage Funds. Each of the Trustees serves as
         Trustee to all three investment companies. The Trustees became trustees
         of The Parkstone Group of Funds and the Parkstone Advantage Fund
         effective August 14, 1998.

                  The Trustees may elect to defer payment of 25% to 100% of the
fees they receive in accordance with a Trustee Deferred Compensation Plan (the
"Plan"). Under the Plan, a Trustee may elect to have his or her deferred fees
treated as if they had been invested by the



                                      -90-
<PAGE>   313

Trust in the shares of one or more portfolios of the Trust and the amount paid
to the Trustee under the Plan will be determined based on the performance of
such investments. Distributions are generally of equal installments over a
period of 2 to 15 years. The Plan will remain unfunded for federal income tax
purposes under the Internal Revenue Code of 1986, as amended (the "Code").
Deferral of Trustee fees in accordance with the Plan will have a negligible
impact on portfolio assets and liabilities and will not obligate the Trust to
retain any trustee or pay any particular level of compensation.

SHAREHOLDER AND TRUSTEE LIABILITY
- ---------------------------------

                  Under Massachusetts law, shareholders of a business trust may,
under certain circumstances, be held personally liable as partners for the
obligations of the trust. However, the Trust's Declaration of Trust provides
that shareholders shall not be subject to any personal liability for the acts or
obligations of the Trust, and that every note, bond, contract, order, or other
undertaking made by the Trust shall contain a provision to the effect that the
shareholders are not personally liable thereunder. The Declaration of Trust
provides for indemnification out of the trust property of any shareholder held
personally liable solely by reason of his or her being or having been a
shareholder and not because of his or her acts or omissions or some other
reason. The Declaration of Trust also provides that the Trust shall, upon
request, assume the defense of any claim made against any shareholder for any
act or obligation of the Trust, and shall satisfy any judgment thereon. Thus,
the risk of a shareholder incurring financial loss on account of shareholder
liability is limited to circumstances in which the Trust itself would be unable
to meet its obligations.

                  The Declaration of Trust states further that no trustee,
officer, or agent of the Trust shall be personally liable for or on account of
any contract, debt, tort, claim, damage, judgment or decree arising out of or
connected with the administration or preservation of the trust estate or the
conduct of any business of the Trust; nor shall any trustee be personally liable
to any person for any action or failure to act except by reason of his or her
own bad faith, willful misfeasance, gross negligence, or reckless disregard of
his or her duties as trustee. The Declaration of Trust also provides that all
persons having any claim against the trustees or the Trust shall look solely to
the trust property for payment. With the exceptions stated, the Declaration of
Trust provides that a trustee is entitled to be indemnified against all
liabilities and expense, reasonably incurred by him in connection with the
defense or disposition of any proceeding in which he or she may be involved or
with which he or she may be threatened by reason of his or her being or having
been a trustee, and that the trustees, have the power, but not the duty, to
indemnify officers and employees of the Trust unless any such person would not
be entitled to indemnification had he or she been a trustee.

by the Trust's Board of Trustees, or by a vote of a majority of the outstanding
shares of such Funds (as defined in the Funds' Prospectus) and a majority of the
trustees who are not parties to the Agreement or interested persons (as defined
in the 1940 Act) of any party by votes cast in person at a meeting called for
such purpose. The Advisory Agreements and Sub-Advisory Agreement may be
terminated by the Trust or the Adviser or sub-advisers on 60 days written
notice, and will terminate immediately in the event of its assignment.

AUTHORITY TO ACT AS INVESTMENT ADVISER
- --------------------------------------

                  Banking laws and regulations, including the Glass-Steagall Act
as presently interpreted by the Board of Governors of the Federal Reserve
System, (a) prohibit a bank holding company registered under the Federal Bank
Holding Company Act of 1956 or any affiliate thereof from sponsoring,
organizing, or controlling a registered, open-end investment company
continuously engaged in the issuance of its shares, but (b) do not prohibit such
a bank holding company or affiliate from acting as investment adviser, transfer
agent, or custodian to such an investment company. The Adviser believes that it
may perform the services for the Fund



                                      -95-
<PAGE>   318

contemplated by its Advisory Agreement with the Trust as described in such
agreement without violation of applicable banking laws or regulations. However,
there are no controlling judicial precedents and future changes in legal
requirements relating to the permissible activities of banks and their
affiliates, as well as future interpretations of present requirements, could
prevent the Adviser from continuing to perform services for the Trust. If the
Adviser were prohibited from providing services to the Fund, the Board of
Trustees would consider selecting another qualified firm. Any new investment
advisory agreement would be subject to shareholder approval.

                  Should future legislative, judicial, or administrative action
prohibit or restrict the proposed activities of the Adviser, or its affiliated
and correspondent banks in connection with shareholder purchases of Fund shares,
the Adviser and its affiliated and correspondent banks might be required to
alter materially or discontinue the services offered by them to shareholders. It
is not anticipated, however, that any resulting change in the Trust's method of
operations would affect its net asset value per share or result in financial
losses to any shareholder.

                  If current restrictions preventing a bank or its affiliates
from legally sponsoring, organizing, controlling, or distributing shares of an
investment company were relaxed, the Adviser, or an affiliate of the Adviser,
would consider the possibility of offering to perform additional services of the
Trust. Legislation modifying such restrictions has been proposed in past
sessions in Congress. It is not possible, of course, to predict whether or in
what form such legislation might be enacted or the terms upon which the Adviser,
or such an affiliate, might offer to provide such services.

ADMINISTRATION AGREEMENT AND SUB-ADMINISTRATION AGREEMENT
- ---------------------------------------------------------

                  The Trust and SEI Investment Mutual Fund Services (the

                  The Administration Agreement provides that the Administrator
shall not be liable for any error of judgment or mistake of law or for any loss

DISTRIBUTION PLANS AND RELATED AGREEMENT
- ----------------------------------------

                  The Distributor acts as distributor of the Fund's shares
pursuant to its Distribution Agreement with the Trust as described in the
Prospectus. Shares are sold on a continuous basis.

                  Pursuant to Rule 12b-1 of the 1940 Act, the Trust has adopted
a Service and Distribution Plan for A and I shares (the "A and I Shares Plan")
and a B Shares Distribution and Servicing Plan ("B Shares Plan," and,
collectively, the "Distribution Plans") which permit the Trust to bear certain
expenses in connection with the distribution of I and A shares, or B shares,
respectively. As required by Rule 12b-1, the Trust's Distribution Plans and
related Distribution Agreements have been approved, and are subject to annual
approval by, a majority of the Trust's Board of Trustees, and by a majority of
the trustees who are not interested persons of the Trust and



                                      -99-
<PAGE>   322

have no direct or indirect interest in the operation of the Distribution Plans
or any agreement relating to the Distribution Plans, by vote cast in person at a
meeting called for the purpose of voting on the Distribution Plans and related
agreements. In compliance with the Rule, the trustees requested and evaluated
information they thought necessary to an informed determination of whether the
Distribution Plans and related agreements should be implemented, and concluded,
in the exercise of reasonable business judgment and in light of their fiduciary
duties, that there is a reasonable likelihood that the Distribution Plans and
related agreements will benefit the Trust and its shareholders.

                  Rule 12b-1 also requires that persons authorized to direct the
disposition of monies payable by a fund (in the Trust's case, the Distributor)
provide for the trustees' review of quarterly reports on the amounts expended
and the purposes for the expenditures.

                  Any change in either Distribution Plan that would materially
increase the distribution expenses of a class would require approval by the
shareholders of such class, but otherwise, such Distribution Plan may be amended
by the trustees, including a majority of the disinterested trustees who do not
have any direct or indirect financial interest in the particular Plan or related
agreement. The Distribution Plans and related agreement may be terminated as to
a particular Fund or class by a vote of the Trust's disinterested trustees or by
vote of the shareholders of the Fund or class in question, on not more than 60
days written notice. The selection and nomination of disinterested trustees has
been committed to the discretion of such disinterested trustees as required by
the Rule.

                  The A and I Shares Plan provides that each fund will reimburse
the Distributor for distribution expenses related to the distribution of A and I
shares in an amount not to exceed .10% per annum of the average aggregate net
assets of such shares. The B Shares Plan provides that each B share class will
compensate the Distributor for distribution of B shares in an amount not to
exceed .75% of the average net assets of such class. Distribution expenses
reimbursable by the Distributor pursuant to each Distribution Plan include
direct and indirect costs and expenses incurred in connection with advertising
and marketing a fund's shares, and direct and indirect costs and expenses of
preparing, printing and distribution of its prospectuses to other than current
shareholders.

                  Under the former A and I Shares Plan and related distribution
agreement (effective for the period from June 1, 1997 to May 1, 1998) each fund
compensated the Distributor for distribution expenses related to the
distribution of I and A shares in an amount not to exceed .10% per annum of the
average aggregate net assets of such shares. This former Plan provided that the
Trust pay the Distributor an annual base fee of $1,250,000 plus incentive fees
based upon asset growth payable monthly and accrued daily by all of the Trusts'
investment funds with respect to the I and A shares.

                  The Distribution Plans have been approved by the Board of
Trustees, and will continue in effect for successive one year periods provided
that such continuance is specifically approved by (1) the vote of a majority of
the trustees who are not parties to either Plan or interested



                                     -100-
<PAGE>   323


persons of any such party and who have no direct or indirect financial interest
in either Plan and (2) the vote of a majority of the entire Board of Trustees.

                  For the fiscal years ended May 31, 1999, the Trust paid the
Distributor the following approximate amounts under the A and I Shares Plan and
B Shares Plan for its distribution services and shareholder service assistance:

                             PORTFOLIO TRANSACTIONS
                             ----------------------

                  Pursuant to its Advisory Agreement with the Trust, IMC is
responsible for making decisions with respect to and placing orders for all
purchases and sales of portfolio securities for the Fund. The Adviser or
Sub-Adviser purchases portfolio securities either directly from the issuer or
from an underwriter or dealer making a market in the securities involved.
Purchases from an underwriter of portfolio securities include a commission or
concession paid by the issuer to the underwriter and purchases from dealers
serving as market makers may include the spread between the bid and asked price.
Transactions on stock exchanges involve the payment of negotiated brokerage
commissions. There is generally no stated commission in the case of securities
traded in the over-the-counter market, but the price includes an undisclosed
commission or mark-up.

                  For the fiscal years ended May 31, 1999, 1998 and 1997, the
Small Cap Value, Equity Growth, Equity Income and Total Return Advantage Funds
paid $1,102,442, $780,933 and

                                     -103-
<PAGE>   326


$421,322; $1,271,614, $1,398,444, and $803,733; $249,890, $86,349 and $102,856;
$0, $0 and $0 in brokerage commissions, respectively. For the same periods, the
Intermediate Bond and Enhanced Income Funds did not pay any brokerage

1, 1997 (commencement of operations) to May 31, 1998, the International Equity,
Small Cap Growth and Core Equity Funds paid $726,464 and $290,141; $503,450 and
$51,366; and $0 and $0, in brokerage commissions, respectively. For the fiscal
year ending May 31, 1999 and the period from April 9, 1998 (commencement of
operations) to May 31, 1998, the Tax Managed Equity Fund paid $26,801 and $0 in
brokerage commissions. For the period from commencement of operations (July 10,
1998) to May 31, 1999, the Equity Index Fund paid brokerage commissions of
$93,484. For the period from commencement of operations (July 10, 1998) to May
31, 1999, the Balanced Allocation Fund paid brokerage commissions of $33,019. As
of May 31, 1999, the Mid Cap Growth, Large Cap Ultra, U.S. Government Income,
Michigan Municipal Bond and Treasury Plus Money Market Funds had not yet
commenced operations.

                  For the fiscal years ended May 31, 1999, 1998, and the period
from September 9, 1996 (date of reorganization of the Predecessor Funds) until
May 31, 1997, the Bond and GNMA Funds paid no brokerage commissions. For the
period from June 1, 1996 until September 9, 1996, the one-month fiscal period
ended May 31, 1996, the Predecessor Bond and GNMA Funds did not pay any
brokerage commissions.

                  For the fiscal years ended May 31, 1999, 1998, 1997, the Ohio

fiscal year 1999 and the period from April 9, 1998 (date of commencement of
operations) until May 31, 1998, the National Tax Exempt Bond Fund paid brokerage
commissions of $0 and $0.

                  While the Adviser (including the Sub-Adviser) generally seeks
competitive spreads or commissions, it may not necessarily allocate each
transaction to the underwriter or dealer charging the lowest spread or
commission available on the transaction. Allocation of transactions, including
their frequency, to various dealers is determined by the Adviser in its best
judgment and in a manner deemed fair and reasonable to shareholders. Under the
Advisory Agreement, pursuant to Section 28(e) of the Securities Exchange Act of
1934, as amended, the Adviser is authorized to negotiate and pay higher
brokerage commissions in exchange for research services rendered by
broker-dealers. Subject to this consideration, broker-dealers who provide
supplemental investment research to the Adviser may receive orders for
transactions by the Fund. Information so received is in addition to and not in
lieu of services required to be performed by the Adviser and does not reduce the
fees payable to the Adviser by the Fund. Such information may be useful to the
Adviser in serving both the Trust and other clients, and, similarly,
supplemental information obtained by the

                                     -104-
<PAGE>   327


placement of business of other clients may be useful to the Adviser in carrying
out its obligations to the Trust.

                  Portfolio securities will not be purchased from or sold to the
Trust's Adviser, Distributor, or any "affiliated person" (as such term is
defined under the 1940 Act) of any of them acting as principal, except to the
extent permitted by the SEC. In addition, the Fund will not give preference to
its Adviser's correspondents with respect to such transactions, securities,
savings deposits, repurchase agreements and reverse repurchase agreements.

                  The Trust is required to identify any securities of its
"regular brokers or dealers" that it has acquired during its most recent fiscal
year. At May 31, 1999, (a) the International Equity Fund had entered into
repurchase transactions with: Goldman Sachs; (b) the Small Cap Growth Fund had
entered into repurchase transactions with: Goldman Sachs; (c) the Tax Managed
Equity Fund had entered into repurchase transactions with: Goldman Sachs; (d)
the Core Equity Fund had entered into repurchase transactions with: Goldman
Sachs; (e) the Bond Fund had entered into repurchase transactions with Goldman
Sachs; (f) the GNMA Fund had entered into repurchase transactions with: Goldman
Sachs; (g) the Tax Exempt Fund had entered into repurchase transactions with
Goldman Sachs; (h) the Money Market Fund had entered into repurchase
transactions with: Prudential Bache Securities; (i) the Government Fund had
entered into repurchase transactions with: Prudential Bache Securities and
Goldman Sachs; and (j) the Treasury Fund had entered into repurchase
transactions with Goldman Sachs; and .

                  While serving as Adviser to the Fund, National City has agreed
to maintain its policy and practice of conducting its Trust Department
independently of its Commercial Department. In making investment recommendations
for the Trust, Trust Department personnel will not inquire or take into
consideration whether the issuer of securities proposed for purchase or sale for
the Trust's account are customers of the Commercial Department. In dealing with
commercial customers, the Commercial Department will not inquire or take into
consideration whether securities of those customers are held by the Trust.

                  Investment decisions for the Fund are made independently from
those for the other Funds and for other investment companies and accounts
advised or managed by the Adviser. Such other Funds, investment companies and
accounts may also invest in the same securities as the Fund. When a purchase or
sale of the same security is made at substantially the same time on behalf of
the Fund and another investment company or account, the transaction will be
averaged as to price, and available investments allocated as to amount, in a
manner which the Adviser believes to be equitable to the Fund and such other
investment company or account. In some instances, this investment procedure may
adversely affect the price paid or received by the Fund or the size of the
position obtained or sold by the Fund. In connection therewith, and to the
extent permitted by law, and by the Advisory Agreement, the Adviser may
aggregate the securities to be sold or purchased for the Fund with those to be
sold or purchased for other investment companies or advisory clients.

         During the last fiscal year, the following Funds engaged in the
directed brokerage transactions in the following amounts and for the following
commissions: the Equity Growth Fund, $304,941,120 in transactions and $253,608
in commissions; the Small Cap Value Fund,

                        YIELD AND PERFORMANCE INFORMATION
                        ---------------------------------

                  Each Fund's "yield" described in the Prospectus is calculated
by dividing the Fund's net investment income per share earned during a 30-day
period (or another period permitted by the rules of the SEC) by the net asset
value per share on the last day of the period and annualizing the result on a
semi-annual basis by adding one to the quotient, raising the sum to the power of
six, subtracting one from the result and then doubling the difference. The
Fund's net investment income per share earned during the period is based on the
average daily number of shares outstanding during the period entitled to receive
dividends and includes dividends and interest earned during the period minus
expenses accrued for the period, net of reimbursements. This calculation can be
expressed as follows:

                                                  a-b   to the 6th power
                                    Yield = 2 [(------)                  - 1]
                                                cd + 1

         Where:            a =   dividends and interest earned during the
                                 period.

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

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

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

                  The Equity Income, Balanced Allocation, Total Return
Advantage, Bond, Intermediate Bond, GNMA, Enhanced Income, the Tax-Exempt Funds,
Mid Cap Growth and U.S. Government Income calculate interest earned on debt
obligations held in their portfolios by computing the yield to maturity of each
obligation held by it based on the market value of the obligation (including
actual accrued interest) at the close of business on the last business day of
each 30-day period, or, with respect to obligations purchased during the 30-day
period, the purchase price (plus actual accrued interest) and dividing the
result by 360 and multiplying the quotient by the market value of the obligation
(including actual accrued interest) in order to determine the interest income on
the obligation for each day of the subsequent 30-day period that the obligation
is in the Fund. The maturity of an obligation with a call provision is the next
call date on which the obligation reasonably may be expected to be called or, if
none, the maturity date. With respect to debt obligations purchased by the Fund
at a discount or premium, the formula generally calls for amortization of the
discount or premium. The amortization schedule will be adjusted monthly to
reflect changes in the market values of such debt obligations.

                  Interest earned on tax-exempt obligations that are issued
without original issue discount and have a current market discount is calculated
by using the coupon rate of interest instead of the yield to maturity. In the
case of tax-exempt obligations that are issued with original issue discount but
which have discounts based on current market value that exceed the
then-

                                     -107-
<PAGE>   330

remaining portion of the original issue discount (market discount), the yield to
maturity is the imputed rate based on the original issue discount calculation.
On the other hand, in the case of tax-exempt obligations that are issued with
original issue discount but which have discounts based on current market value
that are less than the then-remaining portion of the original issue discount
(market premium), the yield to maturity is based on the market value.

                  Expenses accrued for the period (variable "b" in the formula)
include all recurring fees charged by the Fund to all shareholder accounts in
proportion to the length of the base period and the Fund's mean (or median)
account size. Undeclared earned income will be subtracted from the net asset
value per share (variable "d" in the formula). Undeclared earned income is the
net investment income which, at the end of the 30-day base period, has not been
declared as a dividend, but is reasonably expected to be and is declared as a
dividend shortly thereafter. For applicable sales charges, see "How to Purchase
and Redeem Shares -- Sales Charges Applicable to Purchases of A Shares" and
"Sales Charges Applicable to Purchases of B Shares" in the Prospectus.

                  The "tax-equivalent yield" is computed by dividing the portion
of a Fund's yield (calculated as above) that is exempt from federal income tax
by one minus a stated federal income tax rate and adding that figure to that
portion, if any, of the Fund's yield that is not exempt from federal income tax.

                  For the 30-day period ended May 31, 1999, the respective
yields of the A and I shares of the Ohio Tax Exempt Bond, Pennsylvania Municipal
Bond and National Tax Exempt Bond Funds were: 3.73% and 3.94%; 3.76% and 3.98%;
and 3.56% and 3.85%, respectively. The tax equivalent yields (assuming a 39.6%
federal tax rate and 6.799% Ohio tax rate for 1998) for the Ohio Tax Exempt Bond
Fund's A and I shares for the same period were 6.99% and 7.38%, respectively.
The tax equivalent yields (assuming a 39.6% federal tax rate and a 2.8%
Pennsylvania tax rate) for the Pennsylvania Tax Exempt Bond Fund's A and I
shares for the same period were 6.53% and 6.91%, respectively. The tax
equivalent yield (assuming a 39.6% federal tax rate) for the National Tax Exempt
Bond Fund's I shares for the same period was 6.37%.

                  For the 30-day period ended May 31, 1999, the yield of the
Class B Shares of the National Tax Exempt Bond Fund was 3.00%.

                  For the 30-day period ended May 31, 1999, the yields of the A
and I shares of the International Equity, Small Cap Value, Small Cap Growth,
Equity Growth, Tax Managed Equity, Core Equity and Equity Income Funds were N/A

                  Each Fund computes its "average annual total return" by
determining the average annual compounded rate of return during specified
periods that would equate the initial amount invested to the ending redeemable
value of such investment by dividing the ending redeemable value of a
hypothetical $1,000 initial payment by $1,000 and raising the quotient to a
power equal to one divided by the number of years (or fractional portion
thereof) covered by the computation and subtracting one from the result. This
calculation can be expressed as follows:

                                         ERV to the 1/nth power
                                    T = [(-----) - 1]
                                            P

         Where:            T =      average annual total return

                           ERV =    ending redeemable value at the end of the
                                    period covered by the computation of a
                                    hypothetical $1,000 payment made at the
                                    beginning of the period

                           P =      hypothetical initial payment of $1,000

                           n =      period covered by the computation,
                                    expressed in terms of years

                  Each Fund computes its aggregate total returns by determining
the aggregate rates of return during specified periods that likewise equate the
initial amount invested to the ending redeemable value of such investment. The
formula for calculating aggregate total return is as follows:

                                       ERV
                                  T = (---) - 1
                                        P

                  The calculations of average annual total return and aggregate
total return assume the reinvestment of all dividends and capital gain
distributions on the reinvestment dates during the period and include all
recurring fees charged to all shareholder accounts, assuming an account size
equal to the Fund's mean (or median) account size for any fees that vary with
the size of the account. The maximum sales load and other charges deducted from
payments are deducted from the initial $1,000 payment (variable "P" in the
formula). The ending redeemable value (variable "ERV" in the formula) is
determined by assuming complete redemption of the hypothetical investment and
the deduction of all contingent deferred sales charges and other nonrecurring
charges at the end of the measuring period covered by the computation.

                  The average annual total returns for the one year period ended
May 31, 1999 were (9.64)% (after taking the sales load into account) and (4.38)%
(without taking into account any sales load), for the Small Cap Value Fund's A

                  Each Fund may also advertise the "aggregate total return" for
its shares which is computed by determining the aggregate compounded rates of
return during specified periods that likewise equate the initial amount invested
to the ending redeemable value of such investment. The formula for calculating
aggregate total return is as follows:

                                                  ERV
                      Aggregate Total Return = [(------)] - 1
                                                   P

                  The above calculations are made assuming that (1) all
dividends and capital gain distributions are reinvested on the reinvestment
dates at the price per Share existing on the

                                     -113-
<PAGE>   336


reinvestment date, (2) all recurring fees charged to all shareholder accounts
are included, and (3) for any account fees that vary with the size of the
account, a mean (or median) account size in a Fund during the periods is
reflected. The ending redeemable value (variable "ERV" in the formula) is
determined by assuming complete redemption of the hypothetical investment after
deduction of all nonrecurring charges at the end of the measuring period.

                  The Funds may also from time to time include discussions or
illustrations of the effects of compounding in Materials. "Compounding" refers
to the fact that, if dividends or other distributions on a Fund's investments
are reinvested by being paid in additional Fund shares, any future income or
capital appreciation of a Fund would increase the value, not only of the
original Fund investment, but also of the additional Fund shares received
through reinvestment. As a result, the value of a Fund's investments would
increase more quickly than if dividends or other distributions had been paid in
cash.

                  In addition, a Fund may also include in Materials discussions
and/or illustrations of the potential investment goals of a prospective
investor, investment management strategies, techniques, policies or investment
suitability of the Fund, high-quality investments, economic conditions, the
relationship between sectors of the economy and the economy as a whole, various
securities markets, the effects of inflation and historical performance of
various asset classes, including but not limited to, stocks, bonds and Treasury
securities. From time to time, Materials may summarize the substance of
information contained in shareholder reports (including the investment
composition of a Fund), as well as the views of the Adviser as to current
market, economic, trade and interest rate trends, legislative, regulatory and
monetary developments, investment strategies and related matters believed to be
of relevance to a Fund. Each Fund may also include in Materials charts, graphs
or drawings which compare the investment objective, return potential, relative
stability and/or growth possibilities of the Fund and/or other mutual funds, or
illustrate the potential risks and rewards of investment in various investment
vehicles, including but not limited to, stocks, bonds, Treasury securities and
shares of the Fund and/or other mutual funds. Materials may include a discussion
of certain attributes or benefits to be derived by an investment in a Fund
and/or other mutual funds (such as value investing, market timing, dollar cost
averaging, asset allocation, constant ratio transfer, automatic accounting
rebalancing, the advantages and disadvantages of investing in tax-deferred and
taxable investments), shareholder profiles and hypothetical investor scenarios,
timely information on financial management, tax and retirement planning and
investment alternatives to certificates of deposit and other financial
instruments. Such Materials may include symbols, headlines or other material
which highlight or summarize the information discussed in more detail therein.


                          STANDARDIZED YIELD QUOTATIONS

                  "Yields," as described in the Prospectus, are calculated
according to formulas prescribed by the SEC. The standardized seven-day yield
for a class of Fund shares is computed by determining the net change, exclusive
of capital changes, in the value of a hypothetical pre-existing account in the
class having a balance of one share at the beginning of the period, subtracting
a hypothetical charge reflecting deductions from shareholder accounts, dividing
the difference by the

                                     -114-
<PAGE>   337


value of the account at the beginning of the base period to obtain the base
period return, and then multiplying the base period return by (365/7). The net
change in the value of an account in a class includes the value of additional
shares purchased with dividends from the original share, and dividends declared
on both the original share and any such additional shares, net of all fees,
other than nonrecurring account or sales charges, that are charged to all
shareholder accounts in proportion to the length of the base period and the
class' mean or median account size. The capital changes to be excluded from the
calculation of the net change in account value are realized gains and losses
from the sale of securities and unrealized appreciation and depreciation. The
"effective yield" for a class of Fund shares is computed by compounding the
unannualized base period return (calculated as above) by adding 1 to the base
period return, raising the sum to a power equal to 365 divided by 7, and
subtracting 1 from the result.

                  The Ohio Municipal, Pennsylvania Tax Exempt and Tax Exempt
Funds' "tax-equivalent yields" are computed by dividing the portion of those
Funds' yields (calculated as above) that is exempt from federal income tax by
one minus a stated federal income tax rate (using 39.6% tax bracket) and adding
that figure to that portion, if any, of the respective Fund's yield that is not
exempt from federal income tax.

                  For the seven-day period ended May 31, 1999, the yields of the
A and I shares of the Pennsylvania Tax Exempt Fund, Tax Exempt Fund, Money
Market Fund, Government Fund and Treasury Fund were 2.78% and 2.93%, 2.73% and
2.87%, 4.42% and 4.57%, 4.33% and 4.48%, and 3.96% and 4.11%, respectively, and
their respective effective yields were 2.82% and 2.97%, 2.76% and 2.91%, 4.52%
and 4.68%, 4.43% and 4.58%, and 4.03% and 4.19%, respectively. For the seven-day
period ended May 31, 1999, the yield of the B shares of the Money Market Fund
was 3.70%.

                  For the Pennsylvania Tax Exempt and Tax Exempt Funds, the
tax-equivalent effective yields (assuming a 39.6% federal tax rate in the case
of both Funds and a 2.8% Pennsylvania tax rate in the case of the Pennsylvania
Tax Exempt Fund) for their A and I shares for the seven-day period ended May 31,
1999 were 4.90% and 5.16%, and 4.57% and 4.82%, respectively.

                  The current yield for each class of shares in a Fund may be
obtained by calling the Trust at the telephone number provided on the cover
page. Quoted yields are not indicative of future yields. Yields will depend upon
factors such as fund maturity, the Fund's expenses and the types of instruments
held by the Fund.

                  The Funds may also from time to time include discussions or
illustrations of the effects of compounding in Materials. "Compounding" refers
to the fact that, if dividends or other distributions on a Fund investment are
reinvested by being paid in additional Fund shares, any future income or capital
appreciation of a Fund would increase the value, not only of the original Fund
investment, but also of the additional Fund shares received through
reinvestment. As a result, the value of the Fund investment would increase more
quickly than if dividends or other distributions had been paid in cash.

                  In addition, the Funds may also include in Materials
discussions and/or illustrations of the potential investment goals of a
prospective investor, investment management strategies, techniques, policies or
investment suitability of a Fund, high-quality investments, economic conditions,
the relationship between sectors of the economy and the economy as a whole,
various securities markets, the effects of inflation and historical performance
of various asset classes, including but not limited to, stocks, bonds and
Treasury securities. From time to time, Materials may summarize the substance of
information contained in shareholder reports (including the investment
composition of a Fund), as well as the views of the Adviser as to current
market, economic, trade and interest rate trends, legislative, regulatory and
monetary developments, investment strategies and related matters believed to be
of relevance to a Fund. The Funds may also include in Materials charts, graphs
or drawings which compare the investment objective, return potential, relative
stability and/or growth possibilities of the Funds and/or other mutual funds, or
illustrate the potential risks and rewards of investment in various investment
vehicles, including but not limited to, stocks, bonds, Treasury securities and
shares of a Fund and/or other mutual funds. Materials may include a discussion
of certain attributes or benefits to be derived by an investment in a Fund
and/or other mutual funds (such as value investing, market timing, dollar cost
averaging, asset allocation, constant ratio transfer, automatic accounting
rebalancing, the advantages and disadvantages of investing in tax-deferred and
taxable investments), shareholder profiles and hypothetical investor scenarios,
timely information on financial management, tax and retirement planning and
investment alternatives to certificates of deposit and other financial
instruments. Such Materials may include symbols, headlines or other material
which highlight or summarize the information discussed in more detail therein.

* Includes the history of a predecessor common trust fund which commenced
  operations July 31, 1994.

                  The Funds may also from time to time include in Materials a
total return figure that is not calculated according to the formulas set forth
above in order to compare more accurately a Fund's performance with other
measures of investment return. For example, in comparing the Fund's total return
with data published by Lipper Analytical Services, Inc., CDA Investment
Technologies, Inc. or Weisenberger Investment Company Service, or with the
performance of an index, the Fund may calculate its aggregate total return for
the period of time specified in the advertisement or communication by assuming
the investment of $10,000 in shares 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 Fund does not, for these purposes, deduct from the initial value
invested or the ending value redeemed any amount representing sales charges. The
Fund will, however, disclose the maximum sales charge and will also disclose
that the performance data do not reflect sales charges and that inclusion of
sale charges would reduce the performance quoted.

                  The Funds may also from time to time include discussions or
illustrations of the effects of compounding in Materials. "Compounding" refers
to the fact that, if dividends or other distributions on the Fund investment are
reinvested by being paid in additional Fund shares, any future income or capital
appreciation of the Fund would increase the value, not only of the original Fund
investment, but also of the additional Fund shares received through
reinvestment. As a result, the value of the Fund investment would increase more
quickly than if dividends or other distributions had been paid in cash.

                  In addition, the Funds may also include in Materials
discussions and/or illustrations of the potential investment goals of a
prospective investor, investment management strategies, techniques, policies or
investment suitability of the Fund, high-quality investments, economic
conditions, the relationship between sectors of the economy and the economy as a
whole, various securities markets, the effects of inflation and historical
performance of various asset classes, including but not limited to, stocks,
bonds and Treasury securities. From time to time, Materials may summarize the

                                   ----------


CORPORATE AND MUNICIPAL LONG-TERM DEBT RATINGS
- ----------------------------------------------

                  The following summarizes the ratings used by Standard & Poor's
for corporate and municipal debt:

                  "AAA" - This designation represents the highest rating
assigned by Standard & Poor's. The obligor's capacity to meet its financial
commitment on the obligation is extremely strong.

                  "AA" - An obligation rated "AA" differs from the highest rated
obligations only in small degree. The obligor's capacity to meet its financial
commitment on the obligation is very strong.

                  "A" - An obligation rated "A" is somewhat more susceptible to
the adverse effects of changes in circumstances and economic conditions than
obligations in higher rated categories. However, the obligor's capacity to meet
its financial commitment on the obligation is still strong.

                  "BBB" - An obligation rated "BBB" exhibits adequate protection
parameters. However, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity of the obligor to meet its financial
commitment on the obligation.

                  "BB," "B," "CCC," "CC" and "C" - Debt is regarded as having
significant speculative characteristics. "BB" indicates the least degree of
speculation and "C" the highest. While such obligations will likely have some
quality and protective characteristics, these may be outweighed by large
uncertainties or major exposures to adverse conditions.

                  "BB" - Debt is less vulnerable to non-payment than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse business, financial or economic conditions which could lead to the
obligor's inadequate capacity to meet its financial commitment on the
obligation.

                  "B" - Debt is more vulnerable to non-payment than obligations
rated "BB", but the obligor currently has the capacity to meet its financial
commitment on the obligation. Adverse business, financial or economic conditions
will likely impair the obligor's capacity or willingness to meet its financial
commitment on the obligation.

                  "CCC" - Debt is currently vulnerable to non-payment, and is
dependent upon favorable business, financial and economic conditions for the
obligor to meet its financial commitment on the obligation. In the event of
adverse business, financial or economic conditions, the obligor is not likely to
have the capacity to meet its financial commitment on the obligation.

                  "CC" - An obligation rated "CCC" is currently highly
vulnerable to non-payment.

                                      A-1
<PAGE>   377


                  "C" - The "C" rating may be used to cover a situation where a
bankruptcy petition has been filed or similar action has been taken, but
payments on this obligation are being continued.

                  "D" - An obligation rated "D" is in payment default. This
rating is used when payments on an obligation are not made on the date due, even
if the applicable grace period has not expired, unless S & P believes that such
payments will be made during such grace period. "D" rating is also used upon the
filing of a bankruptcy petition or the taking of similar action if payments on
an obligation are jeopardized.

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

                  "r" - This rating is attached to highlight derivative, hybrid,
and certain other obligations that S & P believes may experience high volatility
or high variability in expected returns due to non-credit risks. Examples of
such obligations are: securities whose principal or interest return is indexed
to equities, commodities, or currencies; certain swaps and options; and
interest-only and principal-only mortgage securities. The absence of an "r"
symbol should not be taken as an indication that an obligation will exhibit no
volatility or variability in total return.

         The following summarizes the ratings used by Moody's for corporate and
municipal long-term debt:

                  "Aaa" - Bonds are judged to be of the best quality. They carry
the smallest degree of investment risk and are generally referred to as "gilt
edged." 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 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 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 are considered as medium-grade obligations,
(i.e., they are neither highly protected nor poorly secured). Interest payments
and principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable

                                      A-2
<PAGE>   378


over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.

                  "Ba," "B," "Caa," "Ca," and "C" - Bonds that possess one of
these ratings provide questionable protection of interest and principal ("Ba"
indicates speculative elements; "B" indicates a general lack of characteristics
of desirable investment; "Caa" are of poor standing; "Ca" represents obligations
which are speculative in a high degree; and "C" represents the lowest rated
class of bonds). "Caa," "Ca" and "C" bonds may be in default.

                  Con. (---) - Bonds for which the security depends upon the
completion of some act or the fulfillment of some condition are rated
conditionally. These are bonds secured by (a) earnings of projects under
construction, (b) earnings of projects unseasoned in operation experience, (c)
rentals which begin when facilities are completed, or (d) payments to which some
other limiting condition attaches. Parenthetical rating denotes probable credit
stature upon completion of construction or elimination of basis of condition.

                  (P)... - When applied to forward delivery bonds, indicates
that the rating is provisional pending delivery of the bonds. The rating may be
revised prior to delivery if changes occur in the legal documents or the
underlying credit quality of the bonds.


                  Note: Those bonds in the Aa, A, Baa, Ba and B groups which
Moody's believes possess the strongest investment attributes are designated by
the symbols, Aa1, A1, Baa1, Ba1 and B1.

                  The following summarizes the long-term debt ratings used by
Duff & Phelps for corporate and municipal long-term debt:

                  "AAA" - Debt is considered to be of the highest credit
quality. The risk factors are negligible, being only slightly more than for
risk-free U.S. Treasury debt.

                  "AA" - Debt is considered of high credit quality. Protection
factors are strong. Risk is modest but may vary slightly from time to time
because of economic conditions.

                  "A" - Debt possesses protection factors which are average but
adequate. However, risk factors are more variable and greater in periods of
economic stress.

                  "BBB" - Debt possesses below-average protection factors but
such protection factors are still considered sufficient for prudent investment.
Considerable variability in risk is present during economic cycles.

                  "BB," "B," "CCC," "DD," and "DP" - Debt that possesses one of
these ratings is considered to be below investment grade. Although below
investment grade, debt rated "BB" is deemed likely to meet obligations when due.
Debt rated "B" possesses the risk that obligations will not be met when due.
Debt rated "CCC" is well below investment grade and has considerable

                                      A-3

<PAGE>   379

uncertainty as to timely payment of principal, interest or preferred dividends.
Debt rated "DD" is a defaulted debt obligation, and the rating "DP" represents
preferred stock with dividend arrearages.

                  To provide more detailed indications of credit quality, the
"AA," "A," "BBB," "BB" and "B" ratings may be modified by the addition of a plus
(+) or minus (-) sign to show relative standing within these major categories.

                  The following summarizes the ratings used by Fitch for
corporate and municipal 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+."

                  "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 an 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 considered to be 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
securities 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 that,
if not remedied, may lead to default. The ability to meet obligations requires
an advantageous business and economic environment.


                                      A-4

<PAGE>   380

                  "CC" - Bonds are minimally protected. Default in payments of
interest and/or principal seems probable over time.

                  "C" - Bonds are in imminent default in payment of interest or
principal.

                  "DDD," "DD" and "D" - Bonds are in default on interest and/or
principal payments. Such securities are extremely speculative and should be
valued on the basis of their ultimate recovery value in liquidation or
reorganization of the obligor. "DDD" represents the highest potential for
recovery on these securities, and "D" represents the lowest potential for
recovery.

                  To provide more detailed indications of credit quality, the
Fitch ratings from and including "AA" to "C" may be modified by the addition of
a plus (+) or minus (-) sign to show relative standing within these major rating
categories.

                  IBCA assesses the investment quality of unsecured debt with an
original maturity of more than one year which is issued by bank holding
companies and their principal bank subsidiaries. The following summarizes the
rating categories used by IBCA for long-term debt ratings:

                  "AAA" - Obligations for which there is the lowest expectation
of investment risk. Capacity for timely repayment of principal and interest is
substantial, such that adverse changes in business, economic or financial
conditions are unlikely to increase investment risk substantially.

                  "AA" - Obligations for which there is a very low expectation
of investment risk. Capacity for timely repayment of principal and interest is
substantial, such that adverse changes in business, economic or financial
conditions may increase investment risk, albeit not very significantly.

                  "A" - Obligations for which there is a low expectation of
investment risk. Capacity for timely repayment of principal and interest is
strong, although adverse changes in business, economic or financial conditions
may lead to increased investment risk.

                  "BBB" - Obligations for which there is currently a low
expectation of investment risk. Capacity for timely repayment of principal and
interest is adequate, although adverse changes in business, economic or
financial conditions are more likely to lead to increased investment risk than
for obligations in other categories.

                  "BB," "B," "CCC," "CC," and "C" - Obligations are assigned one
of these ratings where it is considered that speculative characteristics are
present. "BB" represents the lowest degree of speculation and indicates a
possibility of investment risk developing. "C" represents the highest degree of
speculation and indicates that the obligations are currently in default.

                  IBCA may append a rating of plus (+) or minus (-) to a rating
below "AAA" to denote relative status within major rating categories.

                  Thomson BankWatch assesses the likelihood of an untimely
repayment of principal or interest over the term to maturity of long term debt
and preferred stock which are issued by United States commercial banks, thrifts
and non-bank banks; non-United States banks; and broker-dealers. The following
summarizes the rating categories used by Thomson BankWatch for long-term debt
ratings:

                  "AAA" - This designation represents the highest category
assigned by Thomson BankWatch to long-term debt and indicates that the ability
to repay principal and interest on a timely basis is extremely high.

                  "AA" - This designation indicates a very strong ability to
repay principal and interest on a timely basis with limited incremental risk
compared to issues rated in the highest category.

                  "A" - This designation indicates that the ability to repay
principal and interest is strong. Issues rated "A" could be more vulnerable to
adverse developments (both internal and external) than obligations with higher
ratings.

                  "BBB" - This designation represents Thomson BankWatch's lowest
investment-grade category and indicates an acceptable capacity to repay
principal and interest. Issues rated "BBB" are, however, more vulnerable to
adverse developments (both internal and external) than obligations with higher
ratings.

                  "BB," "B," "CCC," and "CC," - These designations are assigned
by Thomson BankWatch to non-investment grade long-term debt. Such issues are
regarded as having speculative characteristics regarding the likelihood of
timely payment of principal and interest. "BB" indicates the lowest degree of
speculation and "CC" the highest degree of speculation.

                  "D" - This designation indicates that the long-term debt is in
default.

                  PLUS (+) OR MINUS (-) - The ratings from "AAA" through "CC"
may include a plus or minus sign designation which indicates where within the
respective category the issue is placed.


COMMERCIAL PAPER RATINGS
- ------------------------

                  A Standard & Poor's ("S&P") commercial paper rating is a
current assessment of the likelihood of timely payment of debt having an
original maturity of no more than 365 days. The following summarizes the rating
categories used by Standard and Poor's for commercial paper:

                  "A-1" - Obligations are rated in the highest category
indicating that the obligor's capacity to meet its financial commitment on the
obligation is strong. Within this category,

                                      A-6

<PAGE>   382

certain obligations are designated with a plus sign (+). This indicates that the
obligor's capacity to meet its financial commitment on these obligations is
extremely strong.

                  "A-2" - Obligations are somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions than
obligations in higher rating categories. However, the obligor's capacity to meet
its financial commitment on the obligation is satisfactory.

                  "A-3" - Obligations exhibit adequate protection parameters.
However, adverse economic conditions or changing circumstances are more likely
to lead to a weakened capacity of the obligor to meet its financial commitment
on the obligation.

                  "B" - Obligations are regarded as having significant
speculative characteristics. The obligor currently has the capacity to meet its
financial commitment on the obligation; however, it faces major ongoing
uncertainties which could lead to the obligor's inadequate capacity to meet its
financial commitment on the obligation.

                  "C" - Obligations are currently vulnerable to nonpayment and
are dependent upon favorable business, financial, and economic conditions for
the obligor to meet its financial commitment on the obligation.

                  "D" - Obligations are in payment default. The "D" rating
category is used when payments on an obligation are not made on the date due
even if the applicable grace period has not expired, unless Standard & Poor's
believes that such payments will be made during such grace period. The "D"
rating will be used upon the filing of a bankruptcy petition or the taking of a
similar action if payments on an obligation are jeopardized.

                  Moody's commercial paper ratings are opinions of the ability
of issuers to repay punctually senior debt obligations not having an original
maturity in excess of one year, unless explicitly noted. The following
summarizes the rating categories used by Moody's for commercial paper:

                  "Prime-1" - Issuers (or supporting institutions) have a
superior ability for repayment of senior short-term debt obligations. Prime-1
repayment ability will often be evidenced by many of the following
characteristics: leading market positions in well-established industries; high
rates of return on funds employed; conservative capitalization structure with
moderate reliance on debt and ample asset protection; broad margins in earnings
coverage of fixed financial charges and high internal cash generation; and
well-established access to a range of financial markets and assured sources of
alternate liquidity.

                  "Prime-2" - Issuers (or supporting institutions) have a strong
ability for repayment of senior short-term debt 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,

                                      A-7
<PAGE>   383

may be more subject to variation. Capitalization characteristics, while still
appropriate, may be more affected by external conditions. Ample alternate
liquidity is maintained.

                  "Prime-3" - Issuers (or supporting institutions) have an
acceptable ability for repayment of senior short-term debt obligations. The
effects of industry characteristics and market compositions may be more
pronounced. Variability in earnings and profitability may result in changes in
the level of debt protection measurements and may require relatively high
financial leverage. Adequate alternate liquidity is maintained.

                  "Not Prime" - Issuers do not fall within any of the Prime
rating categories.

                  The three rating categories of Duff & Phelps for investment
grade commercial paper and short-term debt are "D-1," "D-2" and "D-3." Duff &
Phelps employs three designations, "D-1+," "D-1" and "D-1-," within the highest
rating category. The following summarizes the rating categories used by Duff &
Phelps for commercial paper:

                  "D-1+" - Debt possesses highest certainty of timely payment.
Short-term liquidity, including internal operating factors and/or access to
alternative sources of funds, is outstanding, and safety is just below risk-free
U.S. Treasury short-term obligations.

                  "D-1" - Debt possesses very high certainty of timely payment.
Liquidity factors are excellent and supported by good fundamental protection
factors. Risk factors are minor.

                  "D-1-" - Debt possesses high certainty of timely payment.
Liquidity factors are strong and supported by good fundamental protection
factors. Risk factors are very small.

                  "D-2" - Debt possesses good certainty of timely payment.
Liquidity factors and company fundamentals are sound. Although ongoing funding
needs may enlarge total financing requirements, access to capital markets is
good. Risk factors are small.

                  "D-3" - Debt possesses satisfactory liquidity and other
protection factors qualify issues as investment grade. Risk factors are larger
and subject to more variation. Nevertheless, timely payment is expected.

                  "D-4" - Debt possesses speculative investment characteristics.
Liquidity is not sufficient to ensure against disruption in debt service.
Operating factors and market access may be subject to a high degree of
variation.

                  "D-5" - Issuer has failed to meet scheduled principal and/or
interest payments.

                  Fitch IBCA short-term ratings apply to debt obligations that
have time horizons of less than 12 months for most obligations, or up to three
years for U.S. public finance securities. The following summarizes the rating
categories used by Fitch IBCA for short-term obligations:

                                      A-8

<PAGE>   384

                  "F1" - Securities possess the highest credit quality. This
designation indicates the strongest capacity for timely payment of financial
commitments and may have an added "+" to denote any exceptionally strong credit
feature.

                  "F2" - Securities possess good credit quality. This
designation indicates a satisfactory capacity for timely payment of financial
commitments, but the margin of safety is not as great as in the case of the
higher ratings.

                  "F3" - Securities possess fair credit quality. This
designation indicates that the capacity for timely payment of financial
commitments is adequate; however, near-term adverse changes could result in a
reduction to non-investment grade.

                  "B" - Securities possess speculative credit quality. This
designation indicates minimal capacity for timely payment of financial
commitments, plus vulnerability to near-term adverse changes in financial and
economic conditions.

                  "C" - Securities possess high default risk. This designation
indicates that default is a real possibility and that the capacity for meeting
financial commitments is solely reliant upon a sustained, favorable business and
economic environment.

                  "D" - Securities are in actual or imminent payment default.


                  Thomson Financial BankWatch short-term ratings assess the
likelihood of an untimely payment of principal and interest of debt instruments
with original maturities of one year or less. The following summarizes the
ratings used by Thomson Financial BankWatch:

                  "TBW-1" - This designation represents Thomson Financial
BankWatch's highest category and indicates a very high likelihood that principal
and interest will be paid on a timely basis.

                  "TBW-2" - This designation represents Thomson Financial
BankWatch's second-highest category and indicates that while the degree of
safety regarding timely repayment of principal and interest is strong, the
relative degree of safety is not as high as for issues rated "TBW-1."

                  "TBW-3" - This designation represents Thomson Financial
BankWatch's lowest investment-grade category and indicates that while the
obligation is more susceptible to adverse developments (both internal and
external) than those with higher ratings, the capacity to service principal and
interest in a timely fashion is considered adequate.

                  "TBW-4" - This designation represents Thomson Financial
BankWatch's lowest rating category and indicates that the obligation is regarded
as non-investment grade and therefore speculative.

MUNICIPAL NOTE RATINGS
- ----------------------

                  A Standard and Poor's rating reflects the liquidity concerns
and market access risks unique to notes due in three years or less. The
following summarizes the ratings used by Standard & Poor's Ratings Group for
municipal notes:

                  "SP-1" - The issuers of these municipal notes exhibit a strong
capacity to pay principal and interest. Those issues determined to possess very
strong characteristics are given a plus (+) designation.

                  "SP-2" - The issuers of these municipal notes exhibit
satisfactory capacity to pay principal and interest, with some vulnerability to
adverse financial and economic changes over the term of the notes.

                  "SP-3" - The issuers of these municipal notes exhibit
speculative capacity to pay principal and interest.

                  Moody's ratings for state and municipal notes and other
short-term loans are designated Moody's Investment Grade ("MIG") and variable
rate demand obligations are designated Variable Moody's Investment Grade
("VMIG"). Such ratings recognize the differences between short-term credit risk
and long-term risk. The following summarizes the ratings by Moody's Investors
Service, Inc. for short-term notes:

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

                  "MIG-2"/"VMIG-2" - This designation denotes high quality, with
margins of protection ample although not so large as in the preceding group.

                  "MIG-3"/"VMIG-3" - This designation denotes favorable quality,
with all security elements accounted for but lacking the undeniable strength of
the preceding grades. Liquidity and cash flow protection may be narrow and
market access for refinancing is likely to be less well established.

                  "MIG-4"/"VMIG-4" - This designation denotes adequate quality.
Protection commonly regarded as required of an investment security is present
and although not distinctly or predominantly speculative, there is specific
risk.

                  "SG" - This designation denotes speculative quality. Debt
instruments in this category lack of margins of protection.

TAX-EXEMPT COMMERCIAL PAPER RATINGS
- -----------------------------------

                  A Standard & Poor's ("S&P") commercial paper rating is a
current assessment of the likelihood of timely payment of debt having an
original maturity of no more than 365 days. The following summarizes the rating
categories used by Standard and Poor's for commercial paper:

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

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

                  "A-3" - Issues carrying this designation have adequate
capacity for timely payment. They are, however, more vulnerable to the adverse
effects of changes in circumstances than obligations carrying the higher
designations.

                  "B" - Issues are regarded as having only a speculative
capacity for timely payment.

                  "C" - This rating is assigned to short-term debt obligations
with a doubtful capacity for payment.

                  "D" - Issues are in payment default. The "D" rating category
is used when interest payments of principal payments are not made on the date
due, even if the applicable grace period has not expired, unless S&P believes
such payments will be made during such grace period.

                  Moody's commercial paper ratings are opinions of the ability
of issuers to repay punctually senior debt obligations not having an original

characteristics cited above but to a lesser degree. Earnings trends and coverage
ratios, while sound, may be more subject to variation. Capitalization
characteristics, while still appropriate, may be more affected by external
conditions. Ample alternate liquidity is maintained.

                  "Prime-3" - Issuers (or supporting institutions) have an
acceptable ability for repayment of senior short-term debt obligations. The

Operating factors and market access may be subject to a high degree of
variation.

                  "D-5" - Issuer has failed to meet scheduled principal and/or
interest payments.

                  Fitch short-term ratings apply to debt obligations that are
payable on demand or have original maturities of generally up to three years.
The following summarizes the rating categories used by Fitch for short-term
obligations:

                                      A-12

<PAGE>   388

                  "F-1+" - Securities possess exceptionally strong credit
quality. Issues assigned this rating are regarded as having the strongest degree
of assurance for timely payment.

                  "F-1" - Securities possess 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" - Securities possess good credit quality. Issues
assigned this rating have a satisfactory degree of assurance for timely payment,
but the margin of safety is not as great as the "F-1+" and "F-1" ratings.

                  "F-3" - Securities possess fair credit quality. Issues
assigned this rating have characteristics suggesting that the degree of
assurance for timely payment is adequate; however, near-term adverse changes
could cause these securities to be rated below investment grade.

                  "F-S" - Securities possess weak credit quality. Issues
assigned this rating have characteristics suggesting a minimal degree of
assurance for timely payment and are vulnerable to near-term adverse changes in
financial and economic conditions.

                  "D" - Securities are in actual or imminent payment default.

                  "LOC" - The symbol "LOC" indicates that the rating is based on
a letter of credit issued by a commercial bank.

                  Thomson BankWatch short-term ratings assess the likelihood of
an untimely payment of principal and interest of debt instruments with original
maturities of one year or less. The following summarizes the ratings used by
Thomson BankWatch:

                  "TBW-1" - This designation represents Thomson BankWatch's
highest category and indicates a very high likelihood that principal and
interest will be paid on a timely basis.

                  "TBW-2" - This designation represents Thomson BankWatch's
second-highest category and indicates that while the degree of safety regarding
timely repayment of principal and interest is strong, the relative degree of
safety is not as high as for issues rated "TBW-1."

                  "TBW-3" - This designation represents Thomson BankWatch's
lowest investment-grade category and indicates that while the obligation is more
susceptible to adverse developments (both internal and external) than those with
higher ratings, the capacity to service principal and interest in a timely
fashion is considered adequate.

                  "TBW-4" - This designation represents Thomson BankWatch's
lowest rating category and indicates that the obligation is regarded as
non-investment grade and therefore speculative.

adverse financial and economic changes over the term of the notes.

                  "SP-3" - The issuers of these municipal notes exhibit
speculative capacity to pay principal and interest.

                  Moody's ratings for state and municipal notes and other

                                   ----------

                  As stated in the Prospectus, the Small Cap Value, Equity
Growth, Equity Income, Small Cap Growth, International Equity, Equity Index, Tax
Managed Equity and Balanced Allocation Funds (the "Funds") may enter into
certain futures transactions and options for hedging purposes. Such transactions
are described in this Appendix.

INTEREST RATE FUTURES CONTRACTS

                  USE OF INTEREST RATE FUTURES CONTRACTS. Bond prices are
established in both the cash market and the futures market. In the cash market,
bonds are purchased and sold with payment for the full purchase price of the
bond being made in cash, generally within five business days after the trade. In
the futures market, only a contract is made to purchase or sell a bond in the
future for a set price on a certain date. Historically, the prices for bonds
established in the futures markets have tended to move generally in the
aggregate in concert with the cash market prices and have maintained fairly
predictable relationships. Accordingly, the Fund may use interest rate futures
contracts as a defense, or hedge, against anticipated interest rate changes and
not for speculation. As described below, this would include the use of futures
contract sales to protect against expected increases in interest rates and
futures contract purchases to offset the impact of interest rate declines.

                  The Fund presently could accomplish a similar result to that
which it hopes to achieve through the use of futures contracts by selling bonds
with long maturities and investing in bonds with short maturities when interest
rates are expected to increase, or conversely, selling short-term bonds and
investing in long-term bonds when interest rates are expected to decline.
However, because of the liquidity that is often available in the futures market,
the protection is more likely to be achieved, perhaps at a lower cost and
without changing the rate of interest being earned by the Fund, through using
futures contracts.

                  DESCRIPTION OF INTEREST RATE FUTURES CONTRACTS. An interest
rate futures contract sale would create an obligation by the Fund, as seller, to
deliver the specific type of financial instrument called for in the contract at
a specific future time for a specified price. A futures contract purchase would
create an obligation by the Fund, as purchaser, to take delivery of the specific
type of financial instrument at a specific future time at a specific price. The
specific securities delivered or taken, respectively, at settlement date, would
not be determined until at or near that date. The determination would be in
accordance with the rules of the exchange on which the futures contract sale or
purchase was made.

                  Although interest rate futures contracts by their terms call
for actual delivery or acceptance of securities, in most cases the contracts are
closed out before the settlement date without the making or taking of delivery
of securities. Closing out a futures contract sale is effected by the Fund's
entering into a futures contract purchase for the same aggregate amount of the
specific type of financial instrument and the same delivery date. If the price
of the sale exceeds the price of the offsetting purchase, the Fund is
immediately paid the difference and thus realizes a gain. If the offsetting
purchase price exceeds the sale price, the Fund pays the difference and


<PAGE>   391


realizes a loss. Similarly, the closing out of a futures contract purchase is
effected by the Fund entering into a futures contract sale. If the offsetting
sale price exceeds the purchase price, the Fund realizes a gain, and if the
purchase price exceeds the offsetting sale price, the Fund realizes a loss.

                  Interest rate futures contracts are traded in an auction
environment on the floors of several exchanges -- principally, the Chicago Board
of Trade, the Chicago Mercantile Exchange and the New York Futures Exchange. The
Fund would deal only in standardized contracts on recognized exchanges. Each
exchange guarantees performance under contract provisions through a clearing
corporation, a nonprofit organization managed by the exchange membership.

                  A public market now exists in futures contracts covering
various financial instruments including long-term United States Treasury Bonds
and Notes; Government National Mortgage Association (GNMA) modified pass-through
mortgage backed securities; three-month United States Treasury Bills; and
ninety-day commercial paper. The Fund may trade in any interest rate futures
contracts for which there exists a public market, including, without limitation,
the foregoing instruments.

                  EXAMPLE OF FUTURES CONTRACT SALE. The Fund may engage in an
interest rate futures contract sale to maintain the income advantage from
continued holding of a long-term bond while endeavoring to avoid part or all of
the loss in market value that would otherwise accompany a decline in long-term
securities prices. Assume that the market value of a certain security held by
the Fund tends to move in concert with the futures market prices of long-term
United States Treasury bonds ("Treasury bonds"). The adviser wants to fix the
current market value of this fund security until some point in the future.
Assume the fund security has a market value of 100, and the adviser believes
that because of an anticipated rise in interest rates, the value will decline to
95. The Fund might enter into futures contract sales of Treasury bonds for a
equivalent of 98. If the market value of the fund security does indeed decline
from 100 to 95, the equivalent futures market price for the Treasury bonds might
also decline from 98 to 93.

                  In that case, the five point loss in the market value of the
fund security would be offset by the five point gain realized by closing out the
futures contract sale. Of course, the futures market price of Treasury bonds
might well decline to more than 93 or to less than 93 because of the imperfect
correlation between cash and futures prices mentioned below.

                  The adviser could be wrong in its forecast of interest rates
and the equivalent futures market price could rise above 98. In this case, the
market value of the fund securities, including the fund security being
protected, would increase. The benefit of this increase would be reduced by the
loss realized on closing out the futures contract sale.

                  If interest rate levels did not change, the Fund in the above
example might incur a loss (which might be reduced by a offsetting transaction
prior to the settlement date). In each transaction, transaction expenses would
also be incurred.

                  EXAMPLE OF FUTURES CONTRACT PURCHASE. The Fund may engage in
an interest rate futures contract purchase when it is not fully invested in
long-term bonds but wishes to defer for a

                                      B-2
<PAGE>   392

time the purchase of long-term bonds in light of the availability of
advantageous interim investments, e.g., shorter term securities whose yields are
greater than those available on long-term bonds. The Fund's basic motivation
would be to maintain for a time the income advantage from investing in the
short-term securities; the Fund would be endeavoring at the same time to
eliminate the effect of all or part of a expected increase in market price of
the long-term bonds that the Fund may purchase.

                  For example, assume that the market price of a long-term bond
that the Fund may purchase, currently yielding 10%, tends to move in concert
with futures market prices of Treasury bonds. The adviser wishes to fix the
current market price (and thus 10% yield) of the long-term bond until the time
(four months away in this example) when it may purchase the bond. Assume the
long-term bond has a market price of 100, and the adviser believes that, because
of an anticipated fall in interest rates, the price will have risen to 105 (and
the yield will have dropped to about 9 1/2%) in four months. The Fund might
enter into futures contracts purchases of Treasury bonds for an equivalent price
of 98. At the same time, the Fund would assign a pool of investments in
short-term securities that are either maturing in four months or earmarked for
sale in four months, for purchase of the long-term bond at an assumed market
price of 100. Assume these short-term securities are yielding 15%. If the market
price of the long-term bond does indeed rise from 100 to 105, the equivalent
futures market price for Treasury bonds might also rise from 98 to 103. In that
case, the 5 point increase in the price that the Fund pays for the long-term
bond would be offset by the 5 point gain realized by closing out the futures
contract purchase.

                  The adviser could be wrong in its forecast of interest rates;
long-term interest rates might rise to above 10%; and the equivalent futures
market price could fall below 98. If short-term rates at the same time fall to
10% or below, it is possible that the Fund would continue with its purchase
program for long-term bonds. The market price of available long-term bonds would
have decreased. The benefit of this price decrease, and thus yield increase,
will be reduced by the loss realized on closing out the futures contract
purchase.

                  If, however, short-term rates remained above available
long-term rates, it is possible that the Fund would discontinue its purchase
program for long-term bonds. The yield on short-term securities in the Fund,
including those originally in the pool assigned to the particular long-term
bond, would remain higher than yields on long-term bonds. The benefit of this
continued incremental income will be reduced by the loss realized on closing out
the futures contract purchase. In each transaction, expenses would also be
incurred.

INDEX FUTURES CONTRACTS

                  GENERAL. A bond or stock index assigns relative values to the
bonds or stocks included in the index which fluctuates with changes in the
market values of the bonds or stocks included. Some stock index futures
contracts are based on broad market indexes, such as the Standard & Poor's
Ratings Group 500 or the New York Stock Exchange Composite Index. In contrast,
certain exchanges offer futures contracts on narrower market indexes or indexes
based on an industry or market segment, such as oil and gas stocks.

                  Futures contracts are traded on organized exchanges regulated
by the Commodity Futures Trading Commission. Transactions on such exchanges are
cleared through a clearing corporation, which guarantees the performance of the
parties to each contract.

                  The Fund may sell index futures contracts in order to offset a
decrease in market value of its fund securities that might otherwise result from
a market decline. The Fund may do so either to hedge the value of its fund as a
whole, or to protect against declines, occurring prior to sales of securities,
in the value of the securities to be sold. Conversely, the Fund may purchase
index futures contracts in anticipation of purchases of securities. A long
futures position may be terminated without a corresponding purchase of
securities.

                  In addition, the Fund may utilize index futures contracts in
anticipation of changes in the composition of its fund holdings. For example, in
the event that the Fund expects to narrow the range of industry groups
represented in its holdings it may, prior to making purchases of the actual
securities, establish a long futures position based on a more restricted index,
such as an index comprised of securities of a particular industry group. The
Fund may also sell futures contracts in connection with this strategy, in order
to protect against the possibility that the value of the securities to be sold
as part of the restructuring of the fund will decline prior to the time of sale.

MARGIN PAYMENTS

                  Unlike purchase or sales of fund securities, no price is paid
or received by the Fund upon the purchase or sale of a futures contract.
Initially, the Fund will be required to deposit with the broker or in a
segregated account with the Custodian or a subcustodian an amount of cash or
cash equivalents, known as initial margin, based on the value of the contract.
The nature of initial margin in futures transactions is different from that of
margin in security transactions in that futures contract margin does not involve
the borrowing of funds by the customer to finance the transactions. Rather, the
initial margin is in the nature of a performance bond or good faith deposit on
the contract which is returned to the Fund upon termination of the futures
contract assuming all contractual obligations have been satisfied. Subsequent
payments, called variation margin, to and from the broker, will be made on a
daily basis as the price of the underlying instruments fluctuates making the
long and short positions in the futures contract more or less valuable, a
process known as marking-to-the-market. For example, when the Fund has purchased
a futures contract and the price of the contract has risen in response to a rise
in the underlying instruments, that position will have increased in value and
the Fund will be entitled to receive from the broker a variation margin payment
equal to that increase in value. Conversely, where the Fund has purchased a
futures contract and the price of the future contract has declined in response
to a decrease in the underlying instruments, the position would be less valuable
and the Fund would be required to make a variation margin payment to the broker.
At any time prior to expiration of the futures contract, the adviser may elect
to close the position by taking an opposite position, subject to the
availability of a secondary market, which will operate to terminate the Fund's
position in the futures contract. A final determination of variation margin is
then made, additional cash is required to be paid by or released to the Fund,
and the Fund realizes a loss or gain.

RISKS OF TRANSACTIONS IN FUTURES CONTRACTS

                  There are several risks in connection with the use of futures
by the Fund as hedging devices. One risk arises because of the imperfect
correlation between movements in the price of the futures and movements in the
price of the instruments which are the subject of the hedge. The price of the
future may move more than or less than the price of the instruments being
hedged. If the price of the futures moves less than the price of the instruments
which are the subject of the hedge, the hedge will not be fully effective but,
if the price of the instruments being hedged has moved in an unfavorable
direction, the Fund would be in a better position than if it had not hedged at
all. If the price of the instruments being hedged has moved in a favorable
direction, this advantage will be partially offset by the loss on the futures.
If the price of the futures moves more than the price of the hedged instruments,
the Fund will experience either a loss or gain on the futures which will not be
completely offset by movements in the price of the instruments which are the
subject of the hedge. To compensate for the imperfect correlation of movements
in the price of instruments being hedged and movements in the price of futures
contracts, the Fund may buy or sell futures contracts in a greater dollar amount
than the dollar amount of instruments being hedged if the volatility over a
particular time period of the prices of such instruments has been greater than
the volatility over such time period of the futures, or if otherwise deemed to
be appropriate by the advisers. Conversely, the Fund may buy or sell fewer
futures contracts if the volatility over a particular time period of the prices
of the instruments being hedged is less than the volatility over such time
period of the futures contract being used, or if otherwise deemed to be
appropriate by the adviser.

                  Where futures are purchased to hedge against a possible
increase in the price of securities before the Fund is able to invest its cash
(or cash equivalents) in an orderly fashion, it is possible that the market may
decline instead; if the Fund then concludes not to invest its cash at that time
because of concern as to possible further market decline or for other reasons,
the Fund will realize a loss on the futures contract that is not offset by a
reduction in the price of the instruments that were to be purchased.

                  In addition to the possibility that there may be an imperfect
correlation, or no correlation at all, between movements in the futures and the
instruments being hedged, the price of futures may not correlate perfectly with
movement in the cash market due to certain market distortions. Rather than
meeting additional margin deposit requirements, investors may close futures
contracts through off-setting transactions which could distort the normal
relationship between the cash and futures markets. Second, with respect to
financial futures contracts, the liquidity of the futures market depends on
participants entering into off-setting transactions rather than making or taking
delivery. To the extent participants decide to make or take delivery, liquidity
in the futures market could be reduced thus producing distortions. Third, from
the point of view of speculators, the deposit requirements in the futures market
are less onerous than margin requirements in the securities market. Therefore,
increased participation by speculators in the futures market may also cause
temporary price distortions. Due to the possibility of price distortion in the
futures market, and because of the imperfect correlation between the movements
in the cash market and movements in the price of futures, a correct forecast of
general market trends or interest

                                      B-6

<PAGE>   396

rate movements by the advisers may still not result in a successful hedging
transaction over a short time frame.

                  Positions in futures may be closed out only on an exchange or
board of trade which provides a secondary market for such futures. Although the
Fund intends to purchase or sell futures only on exchanges or boards of trade
where there appear to be active secondary markets, there is no assurance that a
liquid secondary market on any exchange or board of trade will exist for any
particular contract or at any particular time. In such event, it may not be
possible to close a futures investment position, and in the event of adverse
price movements, the Fund would continue to be required to make daily cash
payments of variation margin. However, in the event futures contracts have been
used to hedge fund securities, such securities will not be sold until the
futures contract can be terminated. In such circumstances, an increase in the
price of the securities, if any, may partially or completely offset losses on
the futures contract. However, as described above, there is no guarantee that
the price of the securities will in fact correlate with the price movements in
the futures contract and thus provide an offset on a futures contract.

                  Further, it should be noted that the liquidity of a secondary
market in a futures contract may be adversely affected by "daily price
fluctuation limits" established by commodity exchanges which limit the amount of
fluctuation in a futures contract price during a single trading day. Once the
daily limit has been reached in the contract, no trades may be entered into at a
price beyond the limit, thus preventing the liquidation of open futures
positions. The trading of futures contracts is also subject to the risk of
trading halts, suspensions, exchange or clearing house equipment failures,
government intervention, insolvency of a brokerage firm or clearing house or
other disruptions of normal activity, which could at times make it difficult or
impossible to liquidate existing positions or to recover excess variation margin
payments.

                  Successful use of futures by the Fund is also subject to the
adviser's ability to predict correctly movements in the direction of the market.
For example, if the Fund has hedged against the possibility of a decline in the
market adversely affecting securities held by it and securities prices increase
instead, the Fund will lose part or all of the benefit to the increased value of
its securities which it has hedged because it will have offsetting losses in its
futures positions. In addition, in such situations, if the Fund has insufficient
cash, it may have to sell securities to meet daily variation margin
requirements. Such sales of securities may be, but will not necessarily be, at
increased prices which reflect the rising market. The Fund may have to sell
securities at a time when it may be disadvantageous to do so.

OPTIONS ON FUTURES CONTRACTS

                  The Fund may purchase and write options on the futures
contracts described above. A futures option gives the holder, in return for the
premium paid, the right to buy (call) from or sell (put) to the writer of the
option a futures contract at a specified price at any time during the period of
the option. Upon exercise, the writer of the option is obligated to pay the
difference between the cash value of the futures contract and the exercise
price. Like the buyer or seller of a futures contract, the holder, or writer, of
an option has the right to terminate its position prior to the scheduled
expiration of the option by selling, or purchasing an option of the same series,
at which time the person entering into the closing transaction will realize a
gain or loss. The Fund will be required to deposit initial margin and variation
margin with respect to put and call options on futures contracts written by it
pursuant to brokers' requirements similar to those described above. Net option
premiums received will be included as initial margin deposits.

                  Investments in futures options involve some of the same
considerations that are involved in connection with investments in futures
contracts (for example, the existence of a liquid secondary market). In
addition, the purchase or sale of an option also entails the risk that changes
in the value of the underlying futures contract will not correspond to changes
in the value of the option purchased. Depending on the pricing of the option
compared to either the futures contract upon which it is based, or upon the
price of the securities being hedged, an option may or may not be less risky
than ownership of the futures contract or such securities. In general, the
market prices of options can be expected to be more volatile than the market
prices on the underlying futures contract. Compared to the purchase or sale of
futures contracts, however, the purchase of call or put options on futures
contracts may frequently involve less potential risk to the Fund because the
maximum amount at risk is the premium paid for the options (plus transaction
costs). The writing of an option on a futures contract involves risks similar to
those risks relating to the sale of futures contracts.

OTHER MATTERS

                  Accounting for futures contracts will be in accordance with
generally accepted accounting principles.
