                                  INTRODUCTION

                  The Trust is an open-end management investment company
registered under the Investment Company Act of 1940, as amended (the "1940
Act"). Each Fund consists of a separate pool of assets with separate investment
objectives and policies as described below under "Investment Objectives and
Policies." Each of the Treasury Plus Money Market, Mid Cap Growth, Aggressive
Allocation, Conservative Allocation and U.S. Government Income Funds is
classified as a diversified investment fund under the 1940 Act. The Michigan
Municipal Bond Fund is classified as a non-diversified investment fund under the
1940 Act.

                  Shares of each Fund have been classified into three separate
classes - A shares, B shares and I shares - except for the Treasury Plus Money
Market Fund, which has been classified into two separate classes - A shares and
I shares. A shares, B shares and I shares represent equal pro rata interests in
the investments held in a Fund and are identical in all respects, except that
shares of each class bear separate distribution and/or shareholder
administrative servicing fees and enjoy certain exclusive voting rights on
matters relating to these fees. See "Distribution and Servicing Arrangements,"
"Dividends and Distributions" and "Description of the Trust and Its Shares."
Except as provided below, A shares and B shares are sold through selected
broker-dealers and other financial intermediaries to individual or institutional
customers. A shares are sold with a front-end sales charge. B shares are sold
with a contingent deferred sales charge (back-end charge) imposed on a sliding
schedule when such shares are redeemed.

- ---------------------

(1) The Trust has implemented a plan imposing shareholder servicing fees with
respect to A shares of the Fund. Pursuant to such plan, the Trust enters into
shareholder servicing agreements with certain financial institutions under which
they agree to provide shareholder administrative services to their customers who
beneficially own A shares in consideration for the payment of up to .15% (on an
annualized basis) of the net asset value of such A shares of the Funds. For
further information concerning these plans, see "Distribution and Servicing
Arrangements" below.

(2) The Trust has in effect a 12b-1 Plan for the A and I classes of shares
pursuant to which the Fund's A and I shares may bear fees in an amount of up to
 .10% per annum of such classes' average net assets. As a result of the payment
of sales charges and 12b-1 fees, long-term shareholders may pay more than the
economic equivalent of the maximum sales charges permitted by the National
Association of Securities Dealers, Inc. ("NASD"). The NASD has adopted rules
which generally limit the aggregate sales charges and payment under the Trust's
12b-1 Plans to a certain percentage of total new gross share sales, plus
interest. The Trust would stop accruing 12b-1 and related fees if, to the
extent, and for as long as, such limit would otherwise be exceeded.

(1) The Trust has implemented plans imposing shareholder servicing fees with
respect to A shares and B shares of the Funds. Pursuant to such plans, the Trust
enters into shareholder servicing agreements with certain financial institutions
under which they agree to provide shareholder administrative services to their
customers who beneficially own A shares or B shares in consideration for the
payment of up to .25% (on an annualized basis) of the net asset value of such A
shares or B shares of the Funds. For further information concerning these plans,
see "Distribution and Servicing Arrangements" below.

(2) A reduced sales charge may be available. A contingent deferred sales charge
of 1% may be assessed on certain redemptions of A shares purchased without an
initial sales charge as part of an investment of $1 million or more. See "How to
Purchase and Redeem Shares - Reduced Sales Charges Applicable to Purchases of A
Shares."

(3) This amount applies to redemptions during the first and second years. The
deferred sales charge decreases in subsequent years. For more information, see
"How to Purchase and Redeem Shares - Sales Charges Applicable to Purchases of B
Shares."

(4) The Trust has in effect a 12b-1 Plan for the A and I classes of shares
pursuant to which a Fund's A and I shares may bear fees in an amount of up to
 .10% per annum of such classes' average net assets. A separate 12b-1 Plan exists
with respect to a Fund's B class of shares, pursuant to which a Fund's B shares
may bear fees in an amount of up to .75% of average daily net assets. As a
result of the payment of sales charges and 12b-1 fees, long-term shareholders
may pay more than the economic equivalent of the maximum sales charges permitted
by the National Association of Securities Dealers, Inc. ("NASD"). The NASD has
adopted rules which generally limit the aggregate sales charges and payment
under the Trust's 12b-1 Plans to a certain percentage of total new gross share
sales, plus interest. The Trust would stop accruing 12b-1 and related fees if,
to the extent, and for as long as, such limit would otherwise be exceeded.

(1) The Trust has implemented plans imposing shareholder servicing fees with
respect to A shares and B shares of the Funds. Pursuant to such plans, the Trust
enters into shareholder servicing agreements with certain financial institutions
under which they agree to provide shareholder administrative services to their
customers who beneficially own A shares or B shares in consideration for the
payment of up to .25% (on an annualized basis) of the net asset value of such A
shares or B shares of the Funds. For further information concerning these plans,
see "Distribution and Servicing Arrangements" below.

(2) A reduced sales charge may be available. A contingent deferred sales charge
of 1% may be assessed on certain redemptions of A shares purchased without an
initial sales charge as part of an investment of $1 million or more. See "How to
Purchase and Redeem Shares - Reduced Sales Charges Applicable to Purchases of A
Shares."

(3) This amount applies to redemptions during the first and second years. The
deferred sales charge decreases in subsequent years. For more information, see
"How to Purchase and Redeem Shares - Sales Charges Applicable to Purchases of B
Shares."

(4) The Trust has in effect a 12b-1 Plan for the A and I classes of shares
pursuant to which a Fund's A and I shares may bear fees in an amount of up to
 .10% per annum of such classes' average net assets. A separate 12b-1 Plan exists
with respect to a Fund's B class of shares, pursuant to which a Fund's B shares
may bear fees in an amount of up to .75% of average daily net assets. As a
result of the payment of sales charges and 12b-1 fees, long-term shareholders
may pay more than the economic equivalent of the maximum sales charges permitted
by the National Association of Securities Dealers, Inc. ("NASD"). The NASD has
adopted rules which generally limit the aggregate sales charges and payment
under the Trust's 12b-1 Plans to a certain percentage of total new gross share
sales, plus interest. The Trust would stop accruing 12b-1 and related fees if,
to the extent, and for as long as, such limit would otherwise be exceeded.

                       INVESTMENT OBJECTIVES AND POLICIES

                  The investment objective of each Fund, except the Treasury
Plus Money Market Fund, may be changed without a vote of shareholders, although
the Board of Trustees would only change a Fund's objective upon 30 days' notice
to shareholders. The investment objective of the Treasury Plus Money Market Fund
is fundamental and may not be changed without a vote of the holders of a
majority of the outstanding shares of the Fund. There can be no assurance that a
Fund will achieve its objective. See "Investment Objectives and Policies" in the
Statement of Additional Information for further information on the investments
in which a Fund may invest.

                  During temporary defensive periods as determined by the
Adviser, each of the Funds may hold up to 100% of its total assets in short-term
obligations including domestic bank certificates of deposit, bankers'
acceptances and repurchase agreements secured by bank instruments. However, to
the extent that a Fund is so invested, its investment objective may not be
achieved during that time. Uninvested cash reserves will not earn income.

TREASURY PLUS MONEY MARKET FUND

                  The investment objective of the Treasury Plus Money Market
Fund is to seek current income with liquidity and stability of principal. Under
normal conditions, the Fund invests exclusively in obligations issued or
guaranteed by the U.S. Treasury, its agencies or instrumentalities and in
repurchase agreements related to such securities.

                  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. See "Investment Objectives and
Policies" in the Statement of Additional Information for a more complete
description of eligible securities. 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.

MID CAP GROWTH FUND

                  The investment objective of the Mid Cap Growth Fund is to seek
growth of capital by investing primarily in a diversified portfolio of common
stocks and securities convertible into common stocks.

                  Under normal market conditions, the Fund will invest at least
80% of the value of its total assets in common stocks and securities convertible
into common stocks of companies 



                                      -12-
<PAGE>   18

believed by the Adviser to be characterized by sound management and the ability
to finance expected long-term growth. Under normal market conditions, the Fund
will invest at least 65% of the value of its total assets in common stocks and
securities convertible into common stocks of companies with market
capitalizations between $1 billion and $5 billion. 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 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 between $1 billion and $5 billion. 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.

AGGRESSIVE ALLOCATION FUND AND CONSERVATIVE ALLOCATION FUND

                  The investment objective of the Aggressive Allocation Fund is
to seek capital appreciation and income growth. The investment objective of the
Conservative Allocation Fund is to seek current income and conservation of
capital, with a secondary objective of long-term capital growth.

                  Each Fund may invest in any type or class of security. Under
normal market conditions, each Fund will invest in common stocks, fixed-income
securities, securities convertible into common stocks (i.e., warrants,
convertible preferred stock, fixed-rate preferred stock, convertible fixed
income securities, options and rights). The Aggressive Allocation Fund expects
to invest between 50% and 90% of its net assets in common stocks and securities
convertible into common stocks, between 15% and 40% of its net assets in
fixed-income 



                                      -13-
<PAGE>   19

securities and up to 25% of its net assets in cash and any highly liquid
security with a known market value and a maturity, when issued, of less than
three months ("cash equivalents"). The Aggressive Allocation Fund may invest up
to 25% in foreign securities. The Conservative Allocation Fund anticipates
investing between 25% and 35% of its net assets in common stocks and securities
convertible into common stocks, between 35% and 75% of its net assets in
fixed-income securities and up to 45% of its net assets in cash and cash
equivalents. No more than 15% of the Conservative Allocation Fund's investments
will be in foreign securities.

                  The Conservative Allocation Fund holds common stocks primarily
for the purpose of providing long-term growth of capital. The primary basis for
selecting such stocks will be their potential for long-term capital
appreciation. The Aggressive Allocation Fund will primarily invest in common
stocks for capital appreciation and growth. Each Fund will invest in the common
and preferred stocks of companies with market capitalizations of at least $100
million and which are traded either in established over-the-counter markets or
on national exchanges.

                  Fixed income securities held by the Funds will consist of
bonds, debentures, notes, zero-coupon securities, mortgage-related securities,
asset-backed securities, state, municipal or 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.
Some of the fixed income securities in which the Funds invest may have warrants
or options attached. The Funds may also invest in repurchase agreements.

                  The Funds expect to invest in a variety of U.S. Treasury
obligations, differing in their interest rates, maturities and times of
issuance, as well as "stripped" U.S. Treasury obligations, such as Treasury
receipts issued by the U.S. Treasury representing either future interest or
principal payments, and other obligations issued or guaranteed by the U.S.
government or its agencies or instrumentalities ("Stripped Treasury
Obligations"). See "Other Investment Policies of the Funds-U.S. Treasury
Obligations and Receipts" below.

                  The Funds also expect to invest in bonds, notes and debentures
of a wide range of U.S. corporate issuers. Such obligations, in the case of
debentures, will represent unsecured promises to pay, and in the case of notes
and bond, may be secured by mortgages on real property or security interests in
personal property and will in most cases differ in their interest rates,
maturities and times of issuance.

                  The Funds will invest only in corporate fixed-income
securities which are rated at the time of purchase within the four highest
rating categories assigned by a Rating Agency or, if unrated, which the Adviser
deems present attractive opportunities and are of comparable quality. See "Other
Investment Policies of the Funds-Ratings Criteria" and Appendix A in the
Statement of Additional Information.

                                      -14-
<PAGE>   20

                  The cash equivalent securities in which the Funds normally
invest are short-term obligations (with maturities of 12 months or less)
consisting of domestic and foreign commercial paper, variable amount master
demand notes, bankers' acceptances, certificates of deposit and time deposits of
domestic and foreign branches of U.S. banks and foreign banks and repurchase
agreements. The Funds may also invest in the securities of other investment
companies.

                  The Funds may also invest in obligations of the Export-Import
Bank of the United States, in U.S. dollar-denominated international bonds for
which the primary trading market is in the United States ("Yankee Bonds"), or
for which the primary trading market is abroad ("Eurodollar Bonds"), and in
Canadian bonds and bonds issued by institutions, such as the World Bank and the
European Economic Community, organized for a specific purpose by two or more
sovereign governments ("Supranational Agency Bonds"). The Funds' investments in
foreign securities may be made either directly or through the purchase of ADRs,
EDRs, GDRs and other similar global instruments. The Funds may also invest in
securities issued by foreign branches of U.S. banks and foreign banks, in
Canadian commercial paper, and in Europaper.

                  The amounts invested in equity, fixed income and cash
equivalent securities will vary from time to time, depending on the Adviser's
assessment of business, economic and market conditions, including any potential
advantage of price shifts between the equity markets and the fixed income
markets.

U.S. GOVERNMENT INCOME FUND

                  The investment objective of the U.S. Government Income Fund is
to provide shareholders with a high level of current income and preservation of
capital.

                  Under normal market conditions, the Fund will invest at least
65% of its total assets in obligations issued or guaranteed by the U.S.
government or its agencies or instrumentalities, although up to 35% of the value
of its total assets may be invested in debt securities and preferred stocks of
non-governmental issuers. Consistent with the foregoing, under current market
conditions, the Fund intends to invest up to 80% of the value of its total
assets in mortgage-related securities issued or guaranteed by the U.S.
government or its agencies or instrumentalities. The Fund also may invest up to
35% of its total assets in mortgage-related securities issued by
non-Governmental entities and in other securities described below.

                  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 



                                      -15-
<PAGE>   21

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.

MICHIGAN MUNICIPAL BOND FUND

                  The investment objective of the Michigan Municipal Bond Fund
is to seek income which is exempt from federal income tax and Michigan state
income and intangibles taxes, although such income may be subject to the federal
alternative minimum tax when received by certain shareholders, and preservation
of capital.

                  Under normal market conditions and as a fundamental policy, at
least 80% of the net assets of the Michigan Municipal Bond Fund will be invested
in a portfolio of securities exempt from Michigan State taxes.

                  "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 and intangibles
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 and intangibles taxes.

                  Under normal market conditions, at least 65% of the net assets
of the Fund will be invested in Michigan Municipal Securities consisting of
bonds and notes with remaining maturities at the time of purchase of one year or
more. Quality is the primary consideration in selecting Michigan Municipal
Securities for investment by the Fund.

                  The Fund intends that, under normal market conditions, it will
be invested in long-term Michigan Municipal Securities and that the average
weighted maturity of such investments will be 5 to 12 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 to the Statement of Additional Information.

                                      -16-
<PAGE>   22

                  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 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.

   Special Risk Considerations Applicable to the Michigan Municipal Bond Fund

                                      -17-
<PAGE>   23

                  The economy of the State of Michigan is heavily dependent upon
the automobile manufacturing industry, a highly cyclical industry. This factor
affects the revenue streams of the State of Michigan and its political
subdivisions because it impacts on tax sources, particularly sales taxes, income
taxes and Michigan single business taxes.

                  In 1993 and 1994, Michigan adopted complex statutory and
constitutional changes which, among several other changes in tax methods and
rates, have the effect of imposing limits on annual assessment increases and of
transferring a significant part of the operating cost of public education from
locally based property tax sources to state based sources, including increased
sales tax. These changes will affect state and local revenues of Michigan
governmental units in future years in differing ways, not all of which can be
presently known with certainty.

SPECIAL RISK FACTORS AND CONSIDERATIONS

         Foreign Securities and Currencies

                  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 Funds may be subject to greater
fluctuation in price than securities of domestic companies.

                  To the extent the Mid Cap Growth, Aggressive Allocation,
Conservative Allocation and U.S. Government Income Funds invest 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 those Funds. 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, 



                                      -18-
<PAGE>   24

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 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); 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 Mid Cap Growth, Aggressive Allocation, Conservative Allocation or
U.S. Government Income 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 investing in foreign securities
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 a 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.


OTHER INVESTMENT POLICIES OF THE FUNDS

         Derivative Instruments

                  The Mid Cap Growth, Aggressive Allocation, Conservative
Allocation and U.S. Government Income Funds may purchase certain "derivative"
instruments. Derivative 



                                      -19-
<PAGE>   25

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 a 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 due to the use of derivatives in the equity portion
of each of the Aggressive Allocation and Conservative Allocation Fund's
portfolio of investments will be limited to 33-1/3% of such investments at the
time of the derivative transaction.

                  With respect to the U.S. Government Income Fund and the fixed
income portion of each of the Aggressive Allocation and Conservative Allocation
Fund's investments, the Adviser has determined that the risk features that most
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.

                  The Adviser has adopted the following internal policies
concerning management of the structural risk inherent in derivative instruments.
The risk to a Fund due to the use of such derivatives will be limited to the
principal invested in such instruments. When a 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 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.

                                      -20-
<PAGE>   26

                  The Treasury Plus Money Market Fund and the cash equivalent
portion of each of the Aggressive Allocation and Conservative Allocation Fund's
portfolio of investments are 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 the Treasury Plus
Money Market Fund and the cash equivalent portion of each of the Aggressive
Allocation and Conservative Allocation Fund's assets.

                  The following types of derivative instruments ARE NOT
permitted investments for the Treasury Plus Money Market Fund and the cash
equivalent portion of each of the Aggressive Allocation and Conservative
Allocation Fund's respective 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 Treasury Plus Money Market Fund's assets and
the cash equivalent portion of each of the Aggressive Allocation and
Conservative Allocation 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 Treasury Plus Money Market Fund and the
cash equivalent portion of each of the Aggressive Allocation and Conservative
Allocation Fund's portfolios are:

                  -        securities based on short-term, fixed-rate contracts;
                           and

                  -        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; and

                  -        U.S. Treasury receipts that evidence ownership in
                           either the future interest payments or the future
                           principal payments on U.S. Government obligations.

                           -21-
<PAGE>   27

                  The risk to the Treasury Plus Money Market Fund's assets and
to the cash equivalent portion of the assets of each of the Aggressive
Allocation and Conservative Allocation Funds due to the use of derivatives will
be limited to the principal invested in such instruments.

                  The Adviser will evaluate the risks presented by the
derivative instruments purchased by the Funds, and will determine, in connection
with day-to-day management of the Funds, how they will be used in furtherance of
each Fund's investment objective.

         Futures Contracts and Related Options

                  The Mid Cap Growth Fund 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
U.S. Government Income Fund may invest in futures contracts on U.S. Treasury
obligations. The Aggressive Allocation and Conservative Allocation Funds may
invest in stock index, interest rate, bond index and foreign currency futures
contracts and options on these futures contracts. 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 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.

                  The Mid Cap Growth, Aggressive Allocation, Conservative
Allocation 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.

                  Each of the Mid Cap Growth, Aggressive Allocation,
Conservative Allocation and U.S. Government Income Funds intend to comply with
the regulations of the Commodity 



                                      -22-
<PAGE>   28

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 primary risks associated with the use of futures contracts
and options are:

                    (i) an imperfect correlation between the change in market
value of the securities held by a Fund and the price of the futures contracts
and options;

                   (ii) possible lack of a liquid secondary market for a futures
contract and the resulting inability to close a futures contract when desired;

                  (iii) losses greater than the amount of the principal invested
as initial margin due to unanticipated market movements which are potentially
unlimited; and

                   (iv) the Adviser's ability to predict correctly the direction
of securities prices, interest rates and other economic factors.

         Options

                  Each Fund, other than the Treasury Plus Money Market Fund, 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 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 



                                      -23-
<PAGE>   29

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 other than the Treasury Plus Money Market 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 other than the Treasury Plus Money
Market 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 covered call and
secured put options will not be a primary investment technique of a Fund.

         Foreign Securities and Currencies

                  Each of the Mid Cap Growth, Aggressive Allocation,
Conservative Allocation and U.S. Government Income Funds may invest in
securities issued by foreign issuers either directly or indirectly through
investments in instruments such as ADRs, EDRs and similar instruments (defined
below) as permitted by their respective investment policies. The Funds also may
invest in securities of domestic issuers denominated in foreign currencies and
foreign currencies. See "Special Risk Factors and Consideration - Foreign
Securities and Currencies" above.

         American, Standard & Poor's, MidCap Standard & Poor's, European and 
Global Depository Receipts

                  Each of the Mid Cap Growth, Aggressive Allocation,
Conservative Allocation and U.S. Government Income Funds may invest in ADRs. The
Mid Cap Growth, Aggressive Allocation and Conservative Allocation 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
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.

         Forward Currency Exchange Contracts

                  The Aggressive Allocation and Conservative Allocation Funds
may enter into forward currency exchange contracts in an effort to reduce the
level of volatility caused by changes in foreign currency exchange rates or
where such transactions are deemed economically appropriate for the reduction of
risks inherent in the ongoing management of such Funds. The 

                                      -25-
<PAGE>   31

Funds may not enter into such contracts for speculative purposes. A forward
currency exchange contract is an obligation to purchase or sell a specific
currency at a future date, which may be any fixed number of days from the date
of the contract agreed upon by the parties, at a price set at the time of
contract. Although such contracts tend to minimize the risk of loss due to a
decline in the value of the hedged currency, at the same time they tend to limit
any potential gain that might be realized should the value of such currency
increase. Consequently, a Fund may choose to refrain from entering into such
contracts. In connection with forward currency exchange contracts, a Fund will
create a segregated account of liquid assets or otherwise cover its positions in
accordance with applicable SEC requirements.

         Exchange Rate-Related Securities

                  The Aggressive Allocation and Conservative Allocation 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
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.

         Debt Securities

                  The Aggressive Allocation and Conservative Allocation Funds
may invest in debt securities which may include: equipment lease and trust
certificates; corporate issues; 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, 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 Aggressive Allocation
and Conservative Allocation Funds invest may have warrants or options attached.

                  Fund 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 a 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 


                                      -26-
<PAGE>   32


temporarily reduce the value of the floating rate debt instruments
held by a Fund; conversely, a decline in the level of interest rates may
temporarily increase the value of those investments.

         Ratings Criteria

                  Each of the Aggressive Allocation, Conservative Allocation and
Michigan Municipal Bond Funds 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 Investors Service, Inc. ("Moody's") (Aaa, Aa, A and Baa),
Standard & Poor's Ratings Group ("S&P") (AAA, AA, A and BBB), Fitch Investors
Service, Inc. ("Fitch") (AAA, AA, A and BBB), Duff & Phelps Credit Rating Co.
("Duff") (AAA, AA, A and BBB) or IBCA (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,
Duff or IBCA) 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.

                  Rating symbols are more fully described in Appendix A to the
Statement of Additional Information.

         Mortgage-Backed Securities

                  The Aggressive Allocation, Conservative Allocation and U.S.
Government Income Funds may purchase securities that are secured or backed by
mortgages and are issued by entities such as the 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 a 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 



                                      -27-
<PAGE>   33

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 issuers, whether or not such obligations are subject to guarantees by
the private issuer, 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. If a
mortgage-backed security is purchased at a discount, faster than expected
prepayments will increase the expected yield to maturity and shorten the average
life. Slower than expected prepayments of this kind of mortgage-backed security
will decrease the expected yield to maturity and extend the 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 a Fund, 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.

         Asset-Backed Securities

                  The Aggressive Allocation, Conservative Allocation and U.S.
Government Income Funds may also invest in asset-backed securities including
interests in pools of receivables, such as motor vehicle installment purchase
obligations and credit card receivables. 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 



                                      -28-
<PAGE>   34

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.

                  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. Most
issuers of motor vehicle 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 motor vehicle 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
motor vehicle 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.

         Corporate Debt Obligations

                  Each Fund 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.


         Interest Rate and Total Return Swaps

                  In order to protect its value from interest rate fluctuations,
the Aggressive Allocation, Conservative Allocation and U.S. Government Income
Funds may enter into interest rate swaps. The Aggressive Allocation and
Conservative Allocation Funds may also enter into total return swaps. A Fund
expects to enter into these hedging transactions primarily to preserve a return
or spread of a particular investment or portion of its holdings and to protect
against an increase in the price of securities the Fund anticipates purchasing
at a later date. Swaps involve the exchange by a Fund with another party of
their respective commitments to pay or receive interest (i.e., an exchange of
floating rate payments for fixed rate payments). The net amount of the excess,
if any, of a Fund's obligations over its 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. A Fund will not
enter into any swap unless the unsecured commercial paper, senior debt, or
claims paying ability of the other party is rated either "A" or "A-1" or better
by S&P, Duff or Fitch, or "A" or "P-1" or better by Moody's or the claims paying
ability of the other party is deemed creditworthy and any such obligation the
Fund may have under such an arrangement will be covered by setting aside liquid
high grade securities in a segregated account.

                                      -29-
<PAGE>   35

         U.S. Government Obligations

                  Each Fund may purchase obligations issued or guaranteed by the
U.S. government, its agencies and instrumentalities. Obligations of certain
agencies and instrumentalities of the U.S. government, such as the GNMA, are
supported by the full faith and credit of the U.S. Treasury; 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 Treasury; others, such as those of the FNMA,
are supported by the discretionary authority of the U.S. government to purchase
the agency's obligations; still others, such as those of the Student Loan
Marketing Association, are supported only by the credit of the instrumentality.
No assurance can be given that the U.S. government would provide financial
support to U.S. Government-sponsored 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."

         U.S. Treasury Obligations and Receipts

                  Each Fund may invest in obligations issued or guaranteed by
the U.S. government or its agencies. The Funds 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).

                  The Funds 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.

         Dollar Rolls

                  The Aggressive Allocation, Conservative 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 a Fund for delivery in 



                                      -30-
<PAGE>   36

the current month and a 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 a 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 a Fund to buy a
security. If the broker-dealer to which a Fund sells the security becomes
insolvent, a 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 a Fund is required to repurchase may be worth less than the security
that the Fund originally held.

         Short Sales

                  Each of the Aggressive Allocation, Conservative Allocation and
U.S. Government Income 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.

                  A Fund may only sell securities short "against the box." A
short sale is "against the box" if, at all times during which the short position
is open, the Fund owns at least an equal amount of the securities or securities
convertible into, or exchangeable without further consideration for, securities
of the same issuer as the securities that are sold short.

         Variable and Floating Rate Obligations

                  Each Fund, other than the Treasury Plus Money Market Fund, may
purchase variable and floating rate instruments (including variable amount
master demand notes and adjustable rate mortgages) which are unsecured
instruments that permit the indebtedness thereunder to vary in addition to
providing for periodic adjustments in the interest rate. The absence of an
active secondary market with respect to particular variable and floating rate
instruments could make it difficult for a Fund to dispose of instruments if the
issuer defaulted on its payment obligation or during periods that the Fund is
not entitled to exercise its demand rights, and the Fund could, for these or
other reasons, suffer a loss with respect to such instruments.

                  With respect to the Michigan Municipal Bond Fund, although
there may be no active secondary market in the obligations in which the Fund
invests, the Fund may demand payment of principal and accrued interest at a time
specified in the instruments or may resell them to a third party. Such
obligations may be backed by bank letters of credit, guarantees or other forms
of credit and/or liquidity enhancements issued by banks, other financial
institutions 



                                      -31-
<PAGE>   37

or the U.S. government, its agencies or instrumentalities. The quality of any
credit or liquidity enhancement 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,
the 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.

         When-Issued Securities

                  Each Fund other than the Treasury Plus Money Market Fund may
purchase securities on a "when-issued" or delayed delivery basis. These
transactions are arrangements in which a Fund purchases securities with payment
and delivery scheduled for a future time. Each Fund expects that commitments to
purchase when-issued securities will not exceed 25% of the value of its total
assets under normal market conditions. None of the Funds intends 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 it to miss a price or yield considered to be
attractive.

                  One form of when-issued or delayed delivery security that the
U.S. Government Income Fund 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 the GNMA pass-through security to be
announced on a future settlement date.

         Lending Portfolio Securities

                  In order to generate additional income, each of the Mid Cap
Growth, Aggressive Allocation, Conservative Allocation and U.S. Government
Income Funds may, from time to time, lend its portfolio securities to
broker-dealers, banks or other institutional borrowers. A Fund must receive at
least 100% collateral in the form of cash or U.S. government securities. This
collateral must be valued daily by the 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 any dividends or interest paid on such securities. Loans
are subject to termination by a 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 the Adviser has determined are
creditworthy under guidelines established by the Trust's Board of Trustees.

         Illiquid Securities

                  Each Fund will not invest more than 15% (10% with respect to
the Treasury Plus Money Market Fund) of its net assets in securities that are
illiquid. Illiquid securities would generally include repurchase agreements,
interest rate swaps, guaranteed investment contracts ("GICs") and other
instruments with notice/termination dates in excess of seven days, illiquid


                                      -32-
<PAGE>   38

certificates of participation 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").

                  A 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
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.

         Short-Term Obligations

                  The Mid Cap Growth, Aggressive Allocation, Conservative
Allocation and U.S. Government Income Funds 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.

         Bank Obligations

                  Each Fund other than the Treasury Plus Money Market Fund may
invest in certain bank obligations. 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 of domestic and foreign branches of U.S. banks and
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.

         Commercial Paper

                  Each Fund other than the Treasury Plus Money Market Fund may
invest in commercial paper. 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 "A2" or better by IBCA 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, Aggressive Allocation and Conservative Allocation Funds may invest in
Canadian commercial paper, which is U.S. dollar denominated commercial paper
issued by a Canadian corporation or a Canadian counterpart of a U.S.
corporation. The Aggressive Allocation and Conservative Allocation Funds may
also invest in Europaper, which is U.S. dollar denominated commercial paper of a
foreign issuer.

                                      -33-
<PAGE>   39

         Repurchase Agreements

                  Securities held by each Fund 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 Adviser deems creditworthy under guidelines approved by the Trust's 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 a 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, a Fund 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 agreements, or to the extent that the disposition of such
securities by a 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 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 the Fund under the
1940 Act.

         Reverse Repurchase Agreements

                  Each Fund may borrow funds for temporary purposes by entering
into reverse repurchase agreements in accordance with their respective
investment restrictions. Pursuant to such agreements, a Fund would sell its
portfolio securities to financial institutions such as banks and broker-dealers,
and agree to repurchase them at a mutually agreed upon date and price. Each 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 equal to the repurchase price (including accrued
interest), and will subsequently monitor the account to ensure that 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 a Fund under the 1940 Act.

         Securities of Other Investment Companies

                  Subject to 1940 Act limitations and pursuant to applicable SEC
requirements, each Fund other than the Treasury Plus Money Market Fund may
invest in securities issued by other investment companies which invest in high
quality, short-term debt securities and which 



                                      -34-
<PAGE>   40

determine their net asset value per share based on the amortized cost or
penny-rounding method. The Treasury Plus Money Market Fund may invest in
securities issued by other investment companies which invest exclusively in
direct obligations of the U.S. government, its agencies or instrumentalities and
which determine their net asset value per share based on the amortized cost of
penny-rounding method. As a shareholder of another investment company, each 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 each Fund bears directly in connection
with its own operations. Investment companies in which each 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.

         Municipal Securities

                  The two principal classifications of Michigan Municipal
Securities which may be held by the Michigan Municipal Bond Fund are "general
obligation" securities and "revenue" securities. General obligation securities
are secured by the issuer's pledge of its full faith, credit and taxing power
for the payment of principal and interest. Revenue securities are payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from proceeds of a special excise tax or other specific revenue
source such as the user of the facility being financed. Private activity bonds
held by the Fund are in most cases revenue securities and are not payable from
the unrestricted revenues of the issuer. Consequently, the credit quality of
private activity bonds is usually directly related to the credit standing of the
corporate user of the facility involved.

                  The Fund may also invest in "moral obligation" securities,
which are normally issued by special purpose public authorities. If the issuer
of moral obligation securities is unable to meet its debt service obligations
from current revenues, it may draw on a reserve fund, the restoration of which
is a moral commitment but not a legal obligation of the state or municipality
which created the issuer.

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

                  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. Neither the
Funds nor the Adviser will review the proceedings relating to the issuance of
municipal securities or the basis for such opinions.

                                      -35-
<PAGE>   41

                  Michigan Municipal Securities purchased by the Michigan
Municipal Bond Fund may include rated and unrated variable and floating rate
tax-exempt notes. A variable rate note is one whose terms provide for the
adjustment of its interest rate on set dates and which, upon such adjustment,
can reasonably be expected to have a market value that approximates its par
value. A floating rate note is one whose terms provide for the adjustment of its
interest rate whenever a specified interest rate changes and which, at any time,
can reasonably be expected to have a market value that approximates its par
value. Such notes are frequently not rated by credit rating agencies; however,
unrated variable and floating rate notes purchased by the Fund will be
determined by the Adviser, under guidelines established by the Trust's Board of
Trustees, to be of comparable quality at the time of purchase to rated
instruments eligible for purchase under the Fund's investment policies. In
making such determinations, the Adviser will consider the earning power, cash
flow and other liquidity ratios of the issuers of such notes (such issuers
include financial, merchandising, bank holding and other companies) and will
continuously monitor their financial condition. There may be no active secondary
market with respect to a particular variable or floating rate note.
Nevertheless, the periodic readjustments of their interest rates tend to assure
that their value to the Fund and will approximate their par value. The Fund will
not purchase variable and floating rate notes or any other securities which in
the Adviser's opinion are illiquid if, as a result, more than 15% of the Fund's
total assets will be illiquid.

         Private Activity Bonds

                  The Michigan Municipal Bond Fund may invest in private
activity bonds. It should be noted that the Tax Reform Act of 1986 substantially
revised provisions of prior federal law affecting the issuance and use of
proceeds of certain tax-exempt obligations. A new definition of private activity
bonds applies to many types of bonds, including those which were industrial
development bonds under prior law. Any reference herein to private activity
bonds includes industrial development bonds. Interest on private activity bonds
is tax-exempt (and such bonds will be considered municipal securities for
purposes of this Prospectus) only if the bonds fall within certain defined
categories of qualified private activity bonds and meet the requirements
specified in those respective categories. If the Fund invests in private
activity bonds which fall outside these categories, shareholders may become
subject to the federal alternative minimum tax on that part of the Fund's
distributions derived from interest on such bonds. The Tax Reform Act generally
did not change the federal tax treatment of bonds issued to finance government
operations. For further information relating to the types of private activity
bonds which will be included in income subject to the federal alternative
minimum tax, see "ADDITIONAL INFORMATION CONCERNING TAXES--Additional Tax
Information Concerning the Michigan Municipal Bond Fund" in the Statement of
Additional Information.


         Zero Coupon Obligations

                  The Mid Cap Growth, Aggressive Allocation, Conservative
Allocation, 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


                                      -36-
<PAGE>   42

periodically. The Adviser will consider the liquidity needs of the Fund when any
investment in zero coupon obligations is made.


         Stand-by Commitments

                  The Michigan Municipal Bond Fund may acquire stand-by
commitments with respect to Michigan Municipal Securities held in its portfolio.
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.


         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 municipal leases underlying the certificates of
participation in which the Fund invests will be subject to the same quality
rating standards applicable to Michigan 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.

         Portfolio Turnover

                  The 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 Adviser believes is a temporary disparity in
the normal yield relationship between two securities. Any such trading would
increase a Fund's turnover rate and its transaction costs. Higher portfolio
turnover may result in increased taxable gains to 



                                      -37-
<PAGE>   43

shareholders (see "Taxes" below) and increased expenses paid by the Fund due to
transaction costs. Because the Treasury Plus Money Market Fund intends to invest
primarily in securities with maturities of less than one year (although it may
invest in securities with maturities of up to 13 months) and because the SEC
requires such securities to be excluded from the calculation of portfolio
turnover rate, the portfolio turnover rate with respect to the Treasury Plus
Money Market Fund is expected to be zero for regulatory purposes. Under normal
market conditions, the annual portfolio turnover rate is not expected to exceed
100%, 200%, 200%, 200% and 100% for the Mid Cap Growth, Aggressive Allocation,
Conservative Allocation, U.S. Government Income and Michigan Municipal Bond
Funds, respectively.


                             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 particular Fund's outstanding shares (as defined under "Miscellaneous").
(Other fundamental investment limitations, as well as non-fundamental investment
limitations, are contained in the Statement of Additional Information under
"Investment Objectives and Policies.")

                  The following investment restrictions apply to each Fund
except the Treasury Plus Money Market Fund:

                  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, or in the case of the
                  Michigan Municipal Bond Fund, domestic bank obligations and
                  repurchase agreements secured by such obligations;

                                    (b)   wholly-owned finance companies will be
                  considered to be in the industries of their parents if their
                  activities are primarily related to financing 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; and

                                    (d)   personal credit and business credit
                  businesses will be considered separate industries.

                                      -38-
<PAGE>   44

                  2.   Make loans, except that each 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.

                  None of the Mid Cap Growth, Aggressive Allocation,
Conservative Allocation or U.S. Government Income Funds may:

                                    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.

                  The Treasury Plus Money Market Fund may not:

                                    Purchase securities of any one issuer, other
                  than obligations issued or guaranteed by the U.S. government
                  or its agencies or instrumentalities, if, immediately after
                  such purchase, more than 50% of the value of the Fund's total
                  assets would be invested in such issuer, or the Fund would
                  hold more than 10% of the outstanding voting securities of the
                  issuer, except that 25% or less of the value of such Fund's
                  total assets may be invested without regard to such
                  limitations. There is no limit to the percentage of assets
                  that may be invested in U.S. Treasury bills, notes, or other
                  obligations issued or guaranteed by the U.S. government or its
                  agencies or instrumentalities.

                  Irrespective of the investment restriction above, and pursuant
to Rule 2a-7 under the 1940 Act, the Treasury Plus Money Market Fund will, with
respect to 100% of its total assets, limit its investment in the securities of
any one issuer in the manner provided by such Rule, which limitations are
referred to above under the caption "INVESTMENT OBJECTIVES AND POLICIES -
Treasury Plus Money Market Fund."

                  For purposes of the investment limitations above, a security
is considered to be issued by the governmental entity (or entities) whose assets
and revenues back the security and, with respect to a private activity bond that
is backed only by the assets and revenues of a non-governmental user, a security
is considered to be issued by such non-governmental user.

                  The Treasury Plus Money Market Fund will not:

                                      -39-
<PAGE>   45

                  1.   Purchase any securities which would cause more than 25% 
of the value of the Fund's 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 or its
                  agencies or instrumentalities and repurchase agreements
                  secured by obligations of the U.S. government or its agencies
                  or instrumentalities;

                                    (b)   wholly-owned finance companies will be
                  considered to be in the industries of their parents if their
                  activities are primarily related to financing activities of
                  the parents; and

                                    (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.

                  2.                (a)   Borrow money (not including reverse 
                  repurchase agreements or dollar roll agreements), except that
                  the Fund may borrow from banks for temporary or emergency
                  purposes and then only in amounts up to 10% of its total
                  assets at the time of borrowing (and provided that such bank
                  borrowings, reverse repurchase agreements and dollar roll
                  agreements do not exceed in the aggregate one-third of the
                  Fund's total assets less liabilities other than the
                  obligations represented by the bank borrowings, reverse
                  repurchase agreements and dollar roll agreements), or
                  mortgage, pledge or hypothecate any assets except in
                  connection with a bank borrowing, in amounts not to exceed 30%
                  of the Fund's net assets at the time of borrowing;

                                    (b)   enter into reverse repurchase
                  agreements, dollar roll agreements and other permitted
                  borrowings in amounts exceeding in the aggregate one-third of
                  the Fund's total assets less liabilities other than the
                  obligations represented by such reverse repurchase and dollar
                  roll agreements; and

                                    (c)   issue senior securities except as
                  permitted by the 1940 Act or any rule, order or interpretation
                  thereunder.

                  3.                Make loans, except that the Fund may 
purchase or hold debt instruments and lend portfolio securities in accordance
with its investment objective and policies, make time deposits with financial
institutions and enter into repurchase agreements.

                  For purposes of investment limitation number 1 above only,
such limitation shall not apply to municipal securities or governmental
guarantees of municipal securities, and industrial development bonds or private
activity bonds that are backed only by the assets and revenues of a
non-governmental user shall not be deemed to be municipal securities.

                                      -40-
<PAGE>   46

                  The following additional investment restriction may be changed
without the vote of a majority of the outstanding shares of a Fund.

                  Each Fund will not:

                  Purchase or otherwise acquire any securities if, as a result,
more than 15% (10% in the case of the Treasury Plus Money Market Fund) of the
Fund's net assets would be invested in securities that are illiquid. In addition
to the above investment restrictions, the Funds are subject to certain other
investment restrictions set forth under "INVESTMENT OBJECTIVES AND POLICIES -
Investment Restrictions" in the Statement of Additional Information.

                  For purposes of the above investment limitations, the Funds
treat all supranational organizations as a single industry and each foreign
government (and all of its agencies) as a separate industry. In addition, a
security is considered to be issued by the government entity (or entities) whose
assets and revenues back the security.

                  Except for the Fund's policy on illiquid securities, 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.

                  In addition to the above investment restrictions, the Funds
are subject to certain other investment restrictions set forth under "INVESTMENT
OBJECTIVES AND POLICIES - Investment Restrictions" in the Statement of
Additional Information.


                        YIELD AND PERFORMANCE INFORMATION

                  From time to time, the Trust may quote in advertisements or in
reports to shareholders the "yield" and "effective yield" of the Treasury Plus
Money Market Fund for each class of shares. The "yield" quoted in advertisements
refers to the income generated by an investment in a class of shares of the
Treasury Plus Money Market Fund over a seven-day period identified in the
advertisement. This income is then "annualized." The amount of income so
generated by the investment during that week is assumed to be generated each
week over a 52-week period and is shown as a percentage of the investment. The
"effective yield" for a class of shares is calculated similarly but, when
annualized, then income earned by an investment in the class is assumed to be
reinvested. An effective yield for a class of shares will be slightly higher
than its yield because of the compounding effect of the assumed reinvestment.

                  From time to time, the Trust may quote in advertisements or in
reports to shareholders the Mid Cap Growth, Aggressive Allocation, Conservative
Allocation, U.S. Government Income and Michigan Municipal Bond Fund's yield and
total return data for its A shares, B shares and I shares. The "yield" quoted in
advertisements refers to the income generated by an investment in a class of
shares of a Fund over a 30-day period identified in the advertisement. This
income is then "annualized." The amount of income so generated by the investment
during the 30-day period is assumed to be earned and reinvested at a constant
rate and 



                                      -41-
<PAGE>   47

compounded semi-annually; the annualized income is then shown as a percentage of
the investment.

                  The Michigan Municipal Bond Fund's "tax-equivalent" yield for
a class of shares, which shows the level of taxable yield necessary to produce
an after-tax equivalent to the Michigan Municipal Bond Fund's tax-free yield for
that class, may also be quoted from time to time. It is calculated by increasing
the yield (calculated as above) for a class of shares by the amount necessary to
reflect the payment of federal and Michigan income tax at stated tax rates. The
Michigan Municipal Bond Fund's tax-equivalent yield for a class of shares will
always be higher than its yield.

                  A Fund calculates the total returns for each class of shares
on an "average annual total return" basis for various periods from the date they
commenced investment operations and for other periods as permitted under the
rules of the SEC. Average annual total return reflects the average annual
percentage change in value of an investment in the class over the measuring
period. Total returns for each class of shares may also be calculated on an
"aggregate total return" basis for various periods. Aggregate total return
reflects the total percentage change in value over the measuring period.

                  Both methods of calculating total return reflect changes in
the price of the shares and assume that any dividends and capital gain
distributions made by a Fund with respect to a class during the period are
reinvested in shares of that class. When considering average total return
figures for periods longer than one year, it is important to note that the
annual total return of a class for any one year in the period might have been
greater or less than the average for the entire period. A Fund may also
advertise, from time to time, the total returns of one or more classes of shares
on a year-by-year or other basis for various specified periods by means of
quotations, charts, graphs or schedules.

                  Investors may compare the performance of each class of shares
of a Fund to the performance of other mutual funds with comparable investment
objectives, to various mutual fund or market indices, such as the S&P 500, and
to data or rankings prepared by independent services such as Lipper Analytical
Services, Inc. or other financial or industry publications that monitor the
performance of mutual funds. Comparisons may also be made to indices or data
published in IBC's Money Fund Report, a nationally recognized money market fund
reporting service, Money Magazine, Forbes, Barron's, The Wall Street Journal,
The New York Times, Business Week, U.S.A. Today, CDA/Weisenberger, The American
Banker, Morningstar, Incorporated and other publications of a local, regional or
financial industry nature.

                  The performance of each class of shares of a Fund is based on
historical earnings and will fluctuate and is not intended to indicate future
performance. The investment return and principal value of an investment in a
class will fluctuate so that an investor's shares, when redeemed, may be worth
more or less than their original cost. Performance data may not provide a basis
for comparison with bank deposits and other investments which provide a fixed
yield for a stated period of time. Changes in net asset value of a class should
be considered in ascertaining the total return to shareholders for a given
period. Yield and total return data should also be considered in light of the
risks associated with a Fund's composition, quality, maturity, operating


                                      -42-
<PAGE>   48

expenses and market conditions. Any fees charged by financial institutions (as
described in "How to Purchase and Redeem Shares") are not included in the
computation of performance data but will reduce a shareholder's net return on an
investment in a Fund.

                  Shareholders should note that the yields, effective yields and
total returns of A shares and B shares will be lower than those of the I shares
of a Fund because of the different distribution and/or servicing fees. The total
returns of the B shares will be lower than those of the A shares of a Fund due
to the different distribution fees of the classes. See "Distribution and
Servicing Arrangements."

                  Further information about the performance of a Fund is
available in the annual and semi-annual reports to shareholders. Shareholders
may obtain these materials from the Trust free of charge by calling
1-800-622-FUND(3863).


                                PRICING OF SHARES

                  For processing purchase and redemption orders, the net asset
values per share of each Fund are calculated on each business day as of the
close of trading of the New York Stock Exchange (the "Exchange"), generally 4:00
p.m. Eastern time, with the exception of the Treasury Plus Money Market Fund,
whose net asset value is calculated on each business day first at 1:00 p.m.
Eastern time then as of the close of trading of the Exchange, generally 4:00
p.m. Eastern time. Net asset value per share is determined on each business day,
except those holidays which the Exchange, or banks and trust companies which are
affiliated with National City Corporation (the "Banks"), observe (currently New
Year's Day, Dr. Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day, Christmas Day and,
with respect to the Treasury Plus Money Market Fund, only, Columbus Day and
Veterans Day) ("Business Day").

                  Net asset value per share is calculated by dividing the value
of all securities and other assets allocable to a particular class, less
liabilities charged to that class, by the number of outstanding shares of the
respective class.

                  The assets in the Treasury Plus Money Market Fund are valued
based upon the amortized cost method, which has been determined by the Trust's
Board of Trustees to represent the fair value of the Treasury Plus Money Market
Fund's investments. Amortized cost valuation involves valuing an instrument at
its cost initially and, thereafter, assuming a constant amortization to maturity
of any discount or premium. Although the Trust seeks to maintain the net asset
value per share of the Treasury Plus Money Market Fund at $1.00, there can be no
assurance that the net asset value will not vary.

                  With respect to the Mid Cap Growth, Aggressive Allocation,
Conservative Allocation, U.S. Government Income and Michigan Municipal Bond
Funds, investments in securities traded on an exchange are valued at the last
quoted sale price for a given day, or if a sale is not reported for that day, at
the mean between the most recent quoted bid and asked prices. Other securities
and temporary cash investments acquired more than 60 days from 



                                      -43-
<PAGE>   49

maturity are valued at the mean between the most recent bid and asked prices.
Such valuations are provided by one or more independent pricing services when
such valuations are believed to reflect fair market value. When valuing
securities, pricing services consider institutional size trading in similar
groups of securities and any developments related to specific issues, among
other things. Securities and other assets for which no quotations are readily
available are valued at their fair value under procedures approved by the Board
of Trustees. Absent unusual circumstances, short-term investments having
maturities of 60 days or less are valued on the basis of amortized cost unless
the Trust's Board of Trustees determines that this does not represent fair
value. The net asset value per share of each class of shares of the Mid Cap
Growth, Aggressive Allocation, Conservative Allocation, U.S. Government Income
and Michigan Municipal Bond Funds will fluctuate as the value of their
portfolios change.


                        HOW TO PURCHASE AND REDEEM SHARES

DISTRIBUTOR

                  Shares in the Funds are sold on a continuous basis by the
Trust's sponsor and distributor. The Distributor is a registered broker/dealer
with principal offices located at One Freedom Valley Drive, Oaks, Pennsylvania
19456.

                  The Distributor, Adviser and/or their affiliates, at their own
expense, may provide compensation to dealers and employees of National City
Corporation affiliates in connection with the sale and/or servicing of shares of
the funds of the Trust. Compensation may include financial assistance to dealers
in connection with conferences, sales or training programs for their employees,
seminars for the public, advertising campaigns regarding one or more funds of
the Trust, and/or other dealer-sponsored special events. In some instances, this
compensation may be made available only to certain dealers whose representatives
have sold or are expected to sell a significant amount of such shares.
Compensation may include payment for travel expenses, including lodging,
incurred in connection with trips taken by invited registered representatives
and members of their families to exotic locations within or outside of the
United States for meetings or seminars of a business nature. The Distributor, at
its expense, currently conducts sales contests for dealers in connection with
their sales of shares of the Fund. Dealers may not use sales of the Fund's
shares to qualify for this compensation to the extent such may be prohibited by
the laws of any state or any self-regulatory agency, such as the National
Association of Securities Dealers, Inc.

PURCHASE OF A SHARES AND B SHARES

                  A shares of the Funds are sold with a front-end sales charge
(except that A shares of the Treasury Plus Money Market Fund are sold without a
front-end sales charge). B shares of the Funds are sold subject to a back-end
sales charge. This back-end sales charge declines over time and is known as a
"contingent deferred sales charge." Before choosing between A shares 



                                      -44-
<PAGE>   50

and B shares of a Fund, investors should read "Characteristics of A Shares and B
Shares" and "Factors to Consider When Selecting A Shares or B Shares" below.

                  A shares and B shares are sold to the public ("Investors")
primarily through financial institutions such as banks, brokers and dealers.
Investors may purchase A or B shares directly in accordance with the procedures
set forth below or through procedures established by their financial
institutions in connection with the requirements of their accounts. Investors
purchasing shares of a Fund must specify at the time of investment whether they
are purchasing A shares or B shares.

                  Financial institutions may charge certain account fees
depending on the type of account the Investor has established with the
institution. Investors may be charged a fee if they effect transactions in fund
shares through a broker or agent. (For information on such fees, the Investor
should review his or her agreement with the institution or contact it directly.)
For direct purchases of shares, Investors should call 1-800-622-FUND(3863) or to
speak with a NatCity Investments professional, call 1-888-4NATCTY (462-8289).

                  Shares may be purchased in conjunction with an individual
retirement account ("IRA") and rollover IRAs where a designated custodian acts
as custodian. Investors should contact NatCity Investments, Inc., the
Distributor or their financial institutions for information as to applications
and annual fees. Investors should also consult their tax advisers to determine
whether the benefits of an IRA are available or appropriate.

                  The minimum investment is $500 for the initial purchase of A
shares or B shares in a Fund; there is no minimum for subsequent investments.
All purchases made by check should be in U.S. dollars. Please make the check
payable to Armada Funds (fund name), or, in the case of a retirement account,
the custodian or trustee for the account. When purchases are made by check,
redemptions will not be allowed until the investment being redeemed has been in
the account 15 days. The Trust will not accept third-party checks under any
circumstance.

                  Investments made in A shares or B shares through the Planned
Investment Program ("PIP"), a savings program described below, are not subject
to the minimum initial investment requirements or any minimum account balance
requirements described under "Other Redemption Information." Purchases for an
IRA through the PIP will be considered as contributions for the year in which
the purchases are made.

                  Under a PIP, Investors may add to their investment in A shares
or B shares of a Fund, in a consistent manner each month or quarter, with a
minimum amount of $50. Monies may be automatically withdrawn from a checking or
savings account available through an Investor's financial institution and
invested in additional A shares at the Public Offering Price or B shares at the
net asset value next determined after an order is received by the Trust. An
Investor may apply for participation in a PIP by completing an application
obtained through a financial institution, such as banks, brokers, or dealers
selling A shares or B shares of a Fund, or by calling 1-800-622-FUND(3863). The
program may be modified or terminated by an Investor on 30 days written notice
or by the Trust at any time.

                  All shareholders of record will receive confirmations of share
purchases and redemptions. Financial institutions will be responsible for
transmitting purchase and redemption orders to the Trust's transfer agent, State
Street Bank and Trust Company (the "Transfer Agent"), on a timely basis.

                  The Trust reserves the right to reject any purchase order.

SALES CHARGES APPLICABLE TO PURCHASES OF A SHARES

                  The Public Offering Price for A shares of a Fund is the sum of
the net asset value of the shares being purchased plus any applicable sales
charge per account, which is assessed as follows:

                  With respect to each of the above-mentioned Funds, a 1% sales
charge 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. 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% of the amount invested to the financial institution placing
the purchase order.

                  Under the 1933 Act, the term "underwriter" includes persons
who offer or sell for an issuer in connection with the distribution of a
security or have a direct or indirect participation in such undertaking, but
excludes persons whose interest is limited to a commission from an underwriter
or dealer not in excess of the usual and customary distributors' or sellers'
commission. The Staff of the SEC has expressed the view that persons who receive
90% or more of a sales load may be deemed to be underwriters within the meaning
of this definition. The Dealers' Reallowance may be changed from time to time.

                  No sales charge will be assessed on purchases of A shares made

                  (h)      qualified orders placed by broker-dealers, investment
advisers or financial planners that place trades for their own accounts or the
accounts of their clients and that charge a management consulting or other fee
for their services; and clients of such broker-dealers, investment advisers or
financial planners that place trades for their own accounts if the accounts are
linked to the master account of such broker-dealer, investment adviser or
financial planner on the books and records of the broker or agent.

REDUCED SALES CHARGES APPLICABLE TO PURCHASES OF A SHARES

                  The applicable sales charge may be reduced on purchases of A
shares of each Fund made under the Right of Accumulation or Letter of Intent, as
described below. To qualify for a reduced sales charge, Investors must so notify
their financial institutions or the Trust directly by calling
1-800-622-FUND(3863) at the time of purchase. Reduced sales charges may be
modified or terminated at any time and are subject to confirmation of an
Investor's holdings.

         Concurrent Purchases

                  For purposes of qualifying for a lower sales charge, Investors
have the privilege of combining "concurrent purchases" of A shares of one or
more of the investment funds of the Trust that are sold with a sales charge
(each a "load fund"). The Investor's "concurrent purchases" described above
shall include the combined purchases of the Investor, the Investor's spouse and
children under the age of 21 and the Investor's retirement plan accounts. To
receive the applicable public offering price pursuant to this privilege,
Investors must, at the time of purchase, give the Transfer Agent or the
Distributor sufficient information to permit confirmation of qualification. This
privilege, however, may be modified or eliminated at any time or from time to
time by the Trust without notice.


                                      -48-
<PAGE>   54

         Right of Accumulation

                  Investors may use their aggregate investments in A shares in
determining the applicable sales charge. The investor's "aggregate investments"
may include investments of the Investor, the Investor's spouse and children
under the age of 21 and the Investor's retirement plan accounts. An Investor's
aggregate investment in A shares is the total value (based on the higher of
current net asset value or any Public Offering Price originally paid) of:

                  (a)      current purchases

                  (b)      A shares that are already beneficially owned by the 
Investor for which a sales charge has been paid

                  (c)      A shares that are already beneficially owned by the
Investor which were purchased prior to July 22, 1990

                  (d)      A shares purchased by dividends or capital gains that
are reinvested

                  If, for example, an Investor beneficially owns A shares of the
Conservative Allocation Fund with an aggregate current value of $90,000 and
subsequently purchases A shares of that Fund having a current value of $10,000,
the sales charge applicable to the subsequent purchase would be reduced to 3.75%
of the Public Offering Price.

         Letter of Intent

                  An Investor may qualify for a reduced sales charge immediately
upon signing a nonbinding Letter of Intent stating the Investor's intention to
invest during the next 13-months a specified amount which, if made at one time,
would qualify for a reduced sales charge. The Letter of Intent option is
included on the account application which may be obtained from the Investor's
financial institution or directly from the Trust by calling
1-800-622-FUND(3863). If an Investor so elects, the 13-month period may begin up
to 30 days prior to the Investor's signing the Letter of Intent. The initial
investment under the Letter of Intent must be equal to at least 4.0% of the
amount indicated in the Letter of Intent. During the term of a Letter of Intent,
the Transfer Agent will hold A shares representing 4.0% of the amount indicated
in the Letter of Intent in escrow for payment of a higher sales charge if the
entire amount is not purchased.

                  Upon completing the purchase of the entire amount indicated in
the Letter of Intent, the escrowed shares will be released. If the entire amount
is not purchased within the 13 month period or is redeemed within one year from
the time of fulfillment, the Investor will be required to pay an amount equal to
the difference in the dollar amount of sales charge actually paid and the amount
of sales charge the Investor would have had to pay on the aggregate purchases if
the total of such purchases had been made at a single time.

SALES CHARGES APPLICABLE TO PURCHASES OF B SHARES

                  B shares of a Fund are sold at their net asset value next
determined after a purchase order is received in good form by the Trust's
Distributor. Although Investors pay no front-end sales charge on purchases of B
shares, such shares are subject to a deferred sales charge at the rates set
forth in the chart below if they are redeemed within five years of purchase.
Broker-dealers and other organizations selling B shares to Investors will
receive commissions from the Distributor in connection with sales of B shares.
These commissions may be different than the reallowances or placement fees, if
any, paid to dealers in connection with sales of A shares.

                  The deferred sales charge on B shares is based on the lesser
of the net asset value of the shares on the redemption date or the original cost
of the shares being redeemed. As a result, no sales charge is charged on any
increase in the principal value of an Investor's shares. In addition, a
contingent deferred sales charge will not be assessed on B shares purchased
through reinvestment of dividends or capital gain distributions.

                  The amount of any contingent deferred sales charge an Investor
must pay on B shares depends on the number of years that elapse between the
purchase date and the date such B shares are redeemed. Solely for purposes of
determining the number of years from the time of payment for an Investor's share
purchase, all payments during a month will be aggregated and deemed to have been
made on the first day of the month.

</TABLE>

                  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, 



                                      -50-
<PAGE>   56

unless otherwise designated by the shareholder, from the B shares that have been
held the longest.

                  For example, assume an Investor purchased 100 B shares of the
Mid Cap Growth, Aggressive Allocation, Conservative Allocation, U.S. Government
Income or Michigan Municipal Bond Fund at $10 a share (for a total cost of
$1,000), three years later the shares have a net asset value of $12 per share
and during that time the investor acquired 10 additional shares through dividend
reinvestment. If the Investor then makes one redemption of 50 shares (resulting
in proceeds of $600, 50 shares x $12 per share), the first 10 shares redeemed
will not be subject to the contingent deferred sales charge because they were
acquired through reinvestment of dividends. With respect to the remaining 40
shares redeemed, the contingent deferred sales charge is charged at $10 per
share (because the original purchase price of $10 per share is lower than the
current net asset value of $12 per share). Therefore, only $400 of the $600 the
Investor received from selling his or her shares will be subject to the
contingent deferred sales charge, at a rate of 4.0% (the applicable rate in the
third year after purchase).

                  The proceeds from the contingent deferred sales charge that
the Investor may pay upon redemption go to the Distributor, which may use such
amounts to defray the expenses associated with the distribution-related services
involved in selling B shares. The contingent deferred sales charge, along with
ongoing distribution fees paid with respect to B shares, enables those shares to
be purchased without the imposition of a front-end sales charge.

         Exemptions From Contingent Deferred Sales Charge

                  The following types of redemptions qualify for an exemption
from the contingent deferred sales charge:

                  (a)      exchanges described under "Exchange Privilege 
Applicable to A shares and B shares" below

                  (b)      redemptions in connection with required (or, in some
cases, discretionary) distributions to participants or beneficiaries of an
employee pension, profit-sharing or other trust or qualified retirement or Keogh
plan, individual retirement account or custodial account maintained pursuant to
Section 403(b)(7) of the Internal Revenue Code due to death, disability or the
attainment of a specified age

                  (c)      redemptions effected pursuant to a Fund's right to
liquidate a shareholder's account if the aggregate net asset value of shares
held in the account is less than the minimum account size

                  (d)      redemptions in connection with the death or 
disability of a shareholder

                  (e)      redemptions by a settlor of a living trust

                  (f)      redemptions resulting from a tax-free return of an 
excess contribution pursuant to Section 408(d)(4) or (5) of the Internal Revenue
Code.

CHARACTERISTICS OF A SHARES AND B SHARES

                  The primary difference between A shares and B shares lies in
their sales charge structures and distribution arrangements. An Investor should
understand that the purpose and function of the sales charge structures and
distribution arrangements for both A shares and B shares are the same.

                  A shares are sold at their net asset value plus a front-end
sales charge. This front-end sales charge may be reduced or waived in some
cases. A and I shares are subject to ongoing distribution fees at an annual rate
of up to 0.10% of a Fund's average daily net assets attributable to its A and I
shares.

                  B shares are sold at net asset value without an initial sales
charge. Normally, however, a deferred sales charge is paid if the shares are
redeemed within five years of investment. B shares are subject to ongoing
distribution fees at an annual rate of up to .75% of a Fund's average daily net
assets attributable to its B shares. These ongoing fees, which are higher than
those charged on A shares, will cause B shares to have a higher expense ratio
and pay lower dividends than A shares.

                  B shares which have been outstanding for eight years after the
end of the month in which the shares were initially purchased will automatically
convert to A shares. The purpose of the conversion is to relieve a holder of B
shares of the higher ongoing expenses charged to those shares, after enough time
has passed to allow the Distributor to recover approximately the amount it would
have received if a front-end sales charge had been charged. The conversion from
B shares to A shares takes place at net asset value, as a result of which an
Investor receives dollar-for-dollar the same value of A shares as he or she had
of B shares. As a result of the conversion, the converted shares are relieved of
the distribution and service fees borne by B shares, although they are subject
to the distribution and service fees borne by A shares.

                  B shares acquired through a reinvestment of dividends or
distributions are also converted at the earlier of two dates - eight years after
the beginning of the calendar month in which the reinvestment occurred or the
date of conversion of the most recently purchased B shares that were not
acquired through reinvestment of dividends or distributions. For example, if an
Investor makes a one-time purchase of B shares of a Fund, and subsequently
acquires additional B shares of the Fund only through reinvestment of dividends
and/or distributions, all of such Investor's B shares in the Fund, including
those acquired through reinvestment, will convert to A shares of the Fund on the
same date.

FACTORS TO CONSIDER WHEN SELECTING A SHARES OR B SHARES

                  Before purchasing Shares of a Fund, Investors should consider
whether, during the anticipated life of their investment in the Fund, the
accumulated distribution fees and potential contingent deferred sales charges on
B shares prior to conversion would be less than the initial sales charge and
accumulated distribution fees on A shares purchased at the same time, and to
what extent such differential would be offset by the higher yield of A shares.
In this regard, to the extent that the sales charge for A shares is waived or
reduced by one of the methods described above, investments in A shares become
more desirable. The Trust will refuse all purchase orders for B shares of over
$250,000.

                  Although A shares are subject to a distribution fee, they are
not subject to the higher distribution fee applicable to B shares. For this
reason, A shares can be expected to pay correspondingly higher dividends per
share. However, because initial sales charges are deducted at the time of
purchase, purchasers of A shares that do not qualify for waivers of or
reductions in the initial sales charge would have less of their purchase price
initially invested in a Fund than purchasers of B shares of the Fund.

                  As described above, purchasers of B shares will have more of
their initial purchase price invested. Any positive investment return on this
additional invested amount would partially or wholly offset the expected higher
annual expenses borne by B shares. Because a Fund's future returns cannot be
predicted, there can be no assurance that this will be the case. Holders of B
shares would, however, own shares that are subject to higher annual expenses
and, for a five-year period, such shares would be subject to a contingent
deferred sales charge of up to 5.00% upon redemption, depending upon the year of
redemption. Investors expecting to redeem during this five-year period should
compare the cost of the contingent deferred sales charge plus the aggregate
annual B shares' distribution fees to the cost of the initial sales charge and
distribution fees on the A shares. Over time, the expense of the annual
distribution fees on the B shares may equal or exceed the initial sales charge,
if any, and annual distribution fees applicable to A shares. For example, if net
asset value remains constant, the aggregate distribution fees with respect to B
shares of a Fund would equal or exceed the initial sales charge and aggregate
distribution fees of A shares of the Fund approximately eight years after the
purchase. In order to reduce such fees of Investors that hold B shares for more
than eight years, B shares will be automatically converted to A shares as
described above at the end of such eight-year period.

PURCHASE OF I SHARES

                  I shares are sold primarily to banks and trust companies on
behalf of their trust customers which are affiliated with National City
Corporation (the "Banks"), National Asset Management Corporation ("NAM"),
customers that are large institutions and registered investment advisers and
financial planners affiliated with National City Corporation ("Financial
Advisers") who charge an advisory, consulting or other fee for their services
and buy shares for their own accounts or the accounts of their clients
("Customers"). I shares are sold without a sales charge imposed by the Trust or
the Distributor. However, depending on the terms 



                                      -53-
<PAGE>   59

governing the particular account, the Banks, NAM, or Financial Advisers may
impose account charges such as account maintenance fees, compensating balance
requirements or other charges based upon account transactions, assets or income
which will have the effect of reducing the shareholder's net return on his or
her investment in a Fund. There is no minimum investment.

                  With respect to the Treasury Plus Money Market Fund, Customers
may purchase I shares through procedures established by the Banks, NAM or
Financial Advisers in connection with the requirements of their Customer
accounts. These procedures may include instructions under which a Bank, NAM or
Financial Adviser may automatically "sweep" a Customer's account not less
frequently than weekly and invest amounts in excess of a minimum balance agreed
to by the Bank, NAM or Financial Advisers and the Customer in additional I
shares of a Fund. Customers should obtain information relating to the
requirements of such accounts from their Banks, NAM or Financial Advisers.

                  It is the responsibility of the Banks, NAM and Financial
Advisers to transmit their Customers' purchase orders to the Transfer Agent and
to deliver required funds on a timely basis, in accordance with the procedures
stated above. I shares will normally be held of record by the Banks, NAM, or
Financial Advisers. Confirmations of share purchases and redemptions will be
sent to the Banks, NAM, or Financial Advisers. Beneficial ownership of I shares
will be recorded by the Banks, NAM, or Financial Advisers and reflected in the
account statements provided by them to their Customers.

                  The Trust reserves the right to reject any purchase order.

EFFECTIVE TIME OF PURCHASES

                  Purchase orders for shares of a Fund, other than the Treasury
Plus Money Market Fund, which are received by the Transfer Agent prior to 4:00
p.m. (Eastern Time) on any business day are priced according to the net asset
value per share next determined after receipt of the order plus any applicable
sales charge (the "Public Offering Price"). With respect to each Fund, other
than the Treasury Plus Money Market Fund, immediately available funds must be
received by the Trust's custodian prior to 2:00 p.m. (Eastern Time) on the third
business day following the receipt of such order, at which time the order will
be executed. If funds are not received by such date, the order will not be
accepted and notice thereof will be given to the Bank or financial institution
placing the order. Purchase orders for which payment has not been received or
accepted will be returned after prompt inquiry to the sending Bank or
institution.

                  Purchase orders for shares of the Treasury Plus Money Market
Fund which are received by the Transfer Agent by 1:00 p.m. Eastern time are
processed that day. Purchase orders received after 1:00 p.m. Eastern time are
processed the following business day. Purchases for the Treasury Plus Money
Market Fund will be effected only when federal funds or other funds are
immediately available to the Trust's custodian to make the purchase on the day
the Transfer Agent receives the purchase order. Orders for which funds have not
been received by the Transfer Agent by the prescribed deadline on a given day
will not be accepted and notice thereof will be given promptly to the Bank or
financial institution. In accordance with this 



                                      -54-
<PAGE>   60

policy, purchase orders which are accompanied by a check will be executed on the
second Business Day following receipt of the order at the previous day's net
asset value per share.

REDEMPTION OF A SHARES AND B SHARES

                  Redemption orders received in good order are effected at a
Fund's net asset value per share next determined after receipt of the order by a
Fund. Redemption orders must be placed in writing or by telephone to the same
financial institution that placed the original purchase order. Written requests
for redemptions from an account must be received in good order by the Fund's
Transfer Agent in order to constitute a valid tender for redemption by mail. It
is the responsibility of the financial institutions to transmit redemption
orders to the Transfer Agent. Investors who purchased shares directly from the
Trust may redeem shares in any amount by calling 1-800-622-FUND(3863).
Redemption proceeds are paid by check or credited to the Investor's account with
his or her financial institution. Proceeds from the redemptions of B shares will
be reduced by the amount of any applicable contingent deferred sales charge.

                  In order to arrange for redemption by wire or telephone after
an account has been opened, or to change the bank or account designated to
receive redemption proceeds, a written request must be sent to the Transfer
Agent with a signature guarantee at the address listed under "Written Redemption
Procedures," below.

REDEMPTION OF I SHARES

                  Customers may redeem all or part of their I shares in
accordance with instructions and limitations pertaining to their accounts at the
Banks, NAM or Financial Advisers. It is the responsibility of the Banks, NAM or
Financial Advisers to transmit redemption orders to the Transfer Agent and
credit their Customers' accounts with the redemption proceeds on a timely basis.
Redemption orders are effected at the net asset value per share next determined
after receipt of the order by the Transfer Agent. No charge for wiring
redemption payments is imposed by the Trust, although the Banks, NAM or
Financial Advisers may charge their Customers' accounts for services.
Information relating to such services and charges, if any, is available from the
Banks, NAM or Financial Advisers.

                  If a Customer has agreed with a particular Bank, NAM or
Financial Adviser to maintain a minimum balance in his or her account and the
balance in such account falls below that minimum, the Customer may be obliged to
redeem all or part of his or her I shares to the extent necessary to maintain
the required minimum balance. Customers who have instructed that automatic
purchases and redemptions be made for their accounts receive monthly
confirmations of share transactions.

WRITTEN REDEMPTION PROCEDURES

                  A shareholder who purchased shares directly from the Trust may
redeem shares in any amount by sending a written request to Armada Funds, P.O.
Box 8421, Boston, Massachusetts 02266-8421. Redemption requests must be signed
by each shareholder, including each joint owner on redemption requests for joint
accounts, in the exact manner as the Fund 



                                      -55-
<PAGE>   61

account is registered, and must state the number of shares or the amount to be
redeemed and identify the shareholder account number and tax identification
number.

                  Signature guarantees will be required if: (a) the redemption
request is an amount in excess of $10,000; (b) redemption proceeds are to be
sent to a name/or address that differs from the registered name or address of
record; or (c) a transfer of registration is requested. Otherwise, written
redemption requests by mail may be accepted without a signature guarantee.

                  The Trust may require additional supporting documents for
redemptions made by corporations, fiduciaries, executors, administrators,
trustees, guardians and institutional investors.

TELEPHONE REDEMPTION PROCEDURES

                  A shareholder who purchased shares directly from the Trust may
redeem shares in any amount by calling 1-800-622-FUND(3863) provided the
appropriate election was made on the shareholder's account application.

                  During periods of unusual economic or market changes,
telephone redemptions may be difficult to implement. In such event, shareholders
should mail their redemption requests to their financial institutions or Armada
Funds at the address shown above. Neither the Trust nor its Transfer Agent will
be responsible for the authenticity of instructions received by telephone that
are reasonably believed to be genuine. In attempting to confirm that telephone
instructions are genuine, the Trust and its Transfer Agent will use such
procedures as are considered reasonable, including recording those instructions
and requesting information as to account registration (such as the name in which
an account is registered, the account number and recent transactions in the
account).

                  To the extent that the Trust and its Transfer Agent fail to
use reasonable procedures to verify the genuineness of telephone instructions,
they may be liable for such instructions that prove to be fraudulent and
unauthorized. In all other cases, shareholders will bear the risk of loss for
fraudulent telephone transactions. The Trust reserves the right to refuse a
telephone redemption if it believes it is advisable to do so. Procedures for
redeeming A shares or B shares by telephone may be modified or terminated at any
time by the Trust or the Transfer Agent.

OPTION TO MAKE SYSTEMATIC WITHDRAWALS

                  The Trust has available a Systematic Withdrawal Plan (the
"Plan") for a shareholder who owns shares of any Fund held on the Transfer
Agent's system. The Plan allows the shareholder to have a fixed minimum sum of
$100 distributed at regular intervals. The shareholder's account must have a
minimum value of $1,000 to be eligible for the Plan.

         Withdrawals will be reduced by any applicable contingent deferred sales
charge. Because automatic withdrawals of B shares will be subject to the
contingent deferred sales charge, it may not be in the best interest of B shares
shareholders to make systematic withdrawals. Additional 



                                      -56-
<PAGE>   62

information regarding this service may be obtained from an Investor's financial
institution or the Transfer Agent at 1-800-622-FUND(3863).

CHECKWRITING APPLICABLE TO A SHARES OF THE TREASURY PLUS MONEY MARKET FUND

                  Checkwriting is available from certain institutions with
respect to A shares of the Treasury Plus Money Market Fund. No charge for the
use of the checkwriting privilege is currently imposed by the Trust, although a
charge may be imposed in the future. With this service, a shareholder may write
a check in an amount of $100 or more. To obtain checks, a shareholder must
complete the signature card that accompanies the account application. To
establish this checkwriting service after opening an account in the Treasury
Plus Money Market Fund, the shareholder must contact the Trust by calling
1-800-622-FUND(3863) or by sending a written request to the Armada Funds, P.O.
Box 8421, Boston, Massachusetts 02266-8421 to obtain an application. A signature
guarantee may be required.

                  A shareholder will receive daily dividends declared on the
shares to be redeemed up to the day that a check is presented to the Custodian
for payment. Upon 30 days written notice to shareholders, the checkwriting
privilege may be modified or terminated. An investor cannot close an account in
the Treasury Plus Money Market Fund by writing a check.

OTHER REDEMPTION INFORMATION

                  Payment for redemption orders received by the Transfer Agent
before 1:00 p.m. Eastern time for the Treasury Plus Money Market Fund will be
wired the same day to the Bank or financial institution placing the order.
Payment for redemption orders received after such time will normally be wired
the next business day. The Trust reserves the right to wire redemption proceeds
within seven days after receiving the redemption orders if, in the judgment of
the Adviser, an earlier payment could adversely affect the Trust.

                  Redemption orders in good order are processed at the net asset
value per share next determined after receipt of the order by the Transfer
Agent.

                  WHEN REDEEMING SHARES IN A FUND, SHAREHOLDERS SHOULD INDICATE
WHETHER THEY ARE REDEEMING A SHARES OR B SHARES. In the event a redeeming
shareholder owns both A shares and B shares in a Fund, the A shares will be
redeemed first unless the shareholder indicates otherwise. Due to the relatively
high cost of maintaining small accounts, the Trust reserves the right to redeem,
at net asset value, any account maintained by a shareholder (with the exception
of a Planned Investment Program account) that has a value of less than $500 due
to redemptions (including exchanges as described below) where the shareholder
does not increase the amount in the account to at least $500 upon 60 days
notice.

                  When purchases are made by check, redemptions will not be
allowed until the investment being redeemed has been in the account 15 days. A
shareholder who anticipates the need for more immediate access to his or her
investment should purchase shares by Federal 



                                      -57-
<PAGE>   63

funds, bank wire, certified or cashier's check. Financial institutions normally
impose a charge in connection with the use of bank wires, as well as certified
checks, cashier's checks and Federal funds.

                  The Trust may also redeem shares involuntarily or make payment
for redemption in securities if it appears appropriate to do so in light of the
Trust's responsibilities under the 1940 Act. See "Additional Purchase and
Redemption Information" in the Statement of Additional Information.

                  Payment to Shareholders for shares redeemed will be made
within seven days after receipt of the request for redemption.

EXCHANGE PRIVILEGE APPLICABLE TO A SHARES AND B SHARES

                  Subject to the conditions described below, the Trust offers an
exchange program whereby Investors who have paid a front-end sales charge to
purchase A shares of a Fund offered by the Trust which is sold with a front-end
sales charge (a "load Fund") may exchange those A shares for A shares of another
load Fund, offered by the Trust without the imposition of a front-end sales
charge (each a "no load Fund"), at the net asset value per share on the date of
exchange subject to the following. If a shareholder paid a sales charge on the
previously exchanged A shares that is less than the sales charge applicable to
the A shares sought to be acquired through the exchange, he or she must pay a
sales charge on the exchange equal to such difference. Shareholders may also
exchange A shares of a no load Fund for A shares of another no load Fund at the
net asset value per share without payment of a sales charge.

                  In addition, shareholders of a no load Fund may exchange A
shares for A shares of a load Fund subject to payment of the applicable sales
charge. However, shareholders exchanging A shares of a no load Fund which were
received in a previous exchange transaction involving A shares of a load Fund
will not be required to pay an additional sales charge upon the reinvestment of
the equivalent amount into the A shares of a load Fund except to the extent of
any difference in the applicable sales loads.

                  Shareholders who have purchased B shares of one or more of the
Funds or another investment fund offered by the Trust (including shares acquired
through reinvestment of dividends or distributions on such shares) may exchange
those shares for B shares of another fund without the payment of any contingent
deferred sales charge at the time the exchange is made.

                  No exchange fee is imposed by the Trust. Shareholders
contemplating an exchange should carefully review the Prospectus of the fund
into which the exchange is being considered. An Armada Funds Prospectus may be
obtained from NatCity Investments, Inc., an Investor's financial institution or
by calling 1-800-622-FUND(3863).

                                      -58-
<PAGE>   64

                  Any A shares or B shares exchanged must have a value at least
equal to the minimum initial investment required by the particular investment
fund into which the exchange is being made. Investors should make their exchange
requests in writing or by telephone to the financial institutions through which
they purchased their original A shares or B shares. It is the responsibility of
financial institutions to transmit exchange requests to the Transfer Agent.
Investors who purchased shares directly from the Trust should transmit exchange
requests directly to the Transfer Agent. Exchange requests received by the
Transfer Agent prior to 4:00 p.m. Eastern Time (1:00 p.m. Eastern time for the
Treasury Plus Money Market Fund) will be processed as of the close of business
on the day of receipt. Requests received by the Transfer Agent after the
above-listed times will be processed on the next Business Day.

                  The Trust reserves the right to reject any exchange request.
During periods of unusual economic or market changes, telephone exchanges may be
difficult to implement. In such event, an Investor should mail the exchange
request to his or her financial institution, and an Investor who directly
purchased shares from the Trust should mail the exchange request to the Transfer
Agent. The exchange privilege may be modified or terminated at any time upon 60
days' notice to shareholders.

                  The exchange privilege is a convenient way to respond to
changes in investment goals or in market conditions. This privilege is not
designed for frequent trading in response to short-term market fluctuations.
Management of the Trust reserves the right to limit, amend, impose charges upon,
terminate or otherwise modify the exchange privilege upon 60 days' notice to
shareholders. Except for the Systematic Exchange Program described below, as of
the date of this Prospectus, an Investor is limited to one exchange every two
months during a given 12-month period beginning upon the date of the first
exchange transaction.

SYSTEMATIC EXCHANGE PROGRAM APPLICABLE TO A SHARES AND B SHARES

                  Shares of a Fund may also be purchased through automatic
monthly or quarterly deductions from a shareholder's account from any Armada
money market fund. Under a systematic exchange program, a shareholder enters an
agreement to purchase shares of one or more specified funds over a specified
period of time, and initially purchases shares of one Armada money market fund
in an amount equal to the total amount of the investment. On a monthly or
quarterly basis, a specified dollar amount of shares of the Armada money market
fund is exchanged for shares of the Fund specified.

                  The systematic exchange program of investing a fixed dollar
amount at regular intervals over time has the effect of reducing the average
cost per share of the non-money market funds. This effect also can be achieved
through the Planned Investment Program described previously in this Prospectus.
Because purchases of A shares of non-money market funds may be subject to an
initial sales charge, it may be beneficial for an Investor to execute a Letter
of Intent in indicating an intent to purchase A shares in connection with the
systematic exchange program. Upon exchange into another fund, such shares will
convert to B shares of that fund, and, while the Investor will not pay a
front-end sales load for such purchase, the shares will bear the regular
expenses borne by B shares of such fund. A shareholder may apply for
participation in this program through his or her financial institution or by
calling 1-800-622-FUND(3863).

                                      -59-
<PAGE>   65


                     DISTRIBUTION AND SERVICING ARRANGEMENTS

                  Pursuant to the Trust's Distribution Agreement and Rule 12b-1
under the 1940 Act, the Trust adopted a Service and Distribution Plan For A and
I Share Classes ("A and I Plan") and a separate B Shares Distribution and
Servicing Plan ("B Shares Plan"). Under the A and I Plan, the Trust reimburses
the Distributor for direct and indirect costs and expenses incurred in
connection with advertising, marketing and other distribution services related
to the A and I shares of each of the Trust's investment funds and in preparing
and distributing such shares' prospectus. In the case of each Fund, such
reimbursement shall not exceed .10% per annum of the average aggregate net
assets of its A and I shares. Under the B Shares Plan, the Trust pays the
Distributor up to .75% annually of the average daily net assets of each fund's B
shares for the same types of services provided and expenses assumed as in the A
and I Shares Plan. Such compensation is payable monthly and accrued daily by the
Fund's B shares only.

                  Although B shares are sold without an initial sales charge,
the Distributor pays a sales commission equal to 4.25% of the amount invested
(including a prepaid service fee of 0.25% of the amount invested) to dealers who
sell B shares. These commissions are not paid on exchanges from other Armada
funds or on sales to investors exempt from the contingent deferred sales charge.

                  Under the Shareholder Services Plan relating to each Fund's A
shares and the B Shares Plan, the Trust enters into shareholder servicing
agreements with certain financial institutions. Pursuant to these agreements,
the institutions agree to render shareholder administrative services to their
customers who are the beneficial owners of A or B shares in consideration for
the payment of up to .15% with respect to the Treasury Plus Money Market Fund,
and up to .25% with respect to each other Fund (on an annualized basis) of the
average daily net asset value of such shares.

                  Persons entitled to receive compensation for servicing A or B
shares may receive different compensation with respect to those shares than with
respect to I shares in the same Fund. Shareholder administrative services may
include aggregating and processing purchase and redemption orders, processing
dividend payments from a Fund on behalf of customers, providing information
periodically to customers showing their position in A or B shares, and providing
sub-transfer agent services or the information necessary for sub-transfer agent
services, with respect to A or B shares beneficially owned by customers. Since
financial institutions may charge their customers fees depending on the type of
customer account the Investor has established, beneficial owners of A or B
shares should read this Prospectus in light of the terms and fees governing
their accounts with financial institutions.


                           DIVIDENDS AND DISTRIBUTIONS

                  On each day that the net asset value per share of the Treasury
Plus Money Market Fund is determined, the Fund declares a dividend from net
investment income as of the close of 



                                      -60-
<PAGE>   66

business on the day of declaration. Net investment income for the Treasury Plus
Money Market Fund consists of (a) interest accrued and discount earned
(including both original issue and market discount) on the Fund's assets, (b)
less amortization of market premium on such assets, and the accrued expenses of
the Fund. Fund shares begin earning dividends on the day the purchase order is
executed and continue earning dividends through and including the day before the
redemption order for the shares is executed.

                  Dividends are paid monthly by check, or by wire transfer if
requested in writing by the shareholder to his or her Bank or financial
institution, within five Business Days after the end of each calendar month or
within five Business Days after a shareholder's complete redemption of his or
her shares in the Treasury Plus Money Market Fund.

                  Dividends from the net investment income of the Mid Cap
Growth, Aggressive Allocation and Conservative Allocation Funds are declared and
paid quarterly. Dividends from the net investment income of the U.S. Government
Income and Michigan Municipal Bond Funds are declared daily and paid monthly.
With respect to such Funds, net income for dividend purposes consists of
dividends, distributions and other income on the Fund's assets, less the accrued
expenses of the Fund. Any net realized capital gains will be distributed at
least annually. Dividends and distributions will reduce the Fund's net asset
value per share by the per share amount thereof.

                  Shareholders may elect to have their dividends reinvested in
additional full and fractional Fund shares of the same class of any Armada Funds
at the net asset value of such shares on the ex-dividend date. Shareholders must
make such election, or any revocation thereof, in writing to their Banks or
financial institutions. The election will become effective with respect to
dividends and distributions paid after its receipt.


                                      TAXES
FEDERAL TAXES

                  Each Fund intends to qualify as a separate "regulated
investment company" under the Internal Revenue Code of 1986, as amended (the
"Code"). Such qualification generally relieves the Fund of liability for federal
income taxes to the extent its earnings are distributed in accordance with the
Code.

                  Qualification as a regulated investment company under the Code
for a taxable year requires, among other things, that the Funds distribute to
its shareholders an amount equal to at least the sum of 90% of its investment
company taxable income and 90% of its net tax-exempt interest income, if any,
for such year. In general, a Fund's investment company taxable income will be
the sum of its net investment income and the excess of any net short-term
capital gain for the taxable year over the net long-term capital loss, if any,
for such year. Each Fund intends to distribute substantially all of its
investment company taxable income and net tax-exempt income (such distributions
are known as "exempt-interest dividends") each taxable year. Such distributions
by the Funds will be taxable as ordinary income to their respective shareholders


                                      -61-
<PAGE>   67

who are not currently exempt from federal income taxes, whether such income is
received in cash or reinvested in additional shares. (Federal income taxes for
distributions to an IRA or to a qualified retirement plan are deferred under the
Code.) For corporate shareholders, the dividends received deduction will apply
to such distributions to the extent of the gross amount of qualifying dividends
received by the distributing Fund from domestic corporations for the taxable
year.

                  Exempt-interest dividends may be treated by shareholders as
items of interest excludable from their gross income under Section 103(a) of the
Code unless under the circumstances applicable to the particular shareholder the
exclusion would be disallowed. See the Statement of Additional Information under
"Additional Information Concerning Taxes." The Michigan Municipal Bond Fund does
not intend to earn any investment company taxable income or net long-term
capital gains. To the extent, if any, dividends paid to shareholders of such
Fund are derived from taxable income or from net long-term capital gains, such
dividends will not be exempt from federal income tax and may also be subject to
state and local taxes. None of the distributions by the Michigan Municipal Bond
Fund are expected to be eligible for the dividends received deduction for
corporations.

                  Substantially all of a Fund's net realized long-term capital
gains, if any, will be distributed at least annually to Fund shareholders. Each
Fund will generally have no tax liability with respect to such gains and the
distributions will be taxable to Fund shareholders who are not currently exempt
from federal income taxes as long-term capital gains, regardless of how long the
shareholders have held Fund shares and whether such gains are received in cash
or reinvested in additional shares.

                  Dividends declared in October, November or December of any
year payable to shareholders of record on a specified date before the end of the
year will be deemed to have been received by shareholders and paid by a Fund on
December 31 of such year in the event such dividends are actually paid during
January of the following year.

                  Prior to purchasing Fund shares, the impact of dividends or
distributions which are expected to be declared or have been declared, but not
paid, should be carefully considered. Any dividend or distribution declared
shortly after a purchase of shares prior to the record date will have the effect
of reducing the per share net asset value by the per share amount of the
dividend or distribution. All or a portion of such dividend or distribution,
although in effect a return of capital, may be subject to tax.

                  If the Michigan Municipal Bond Fund holds certain private
activity bonds, shareholders must include as an item of tax preference for
purposes of the federal alternative minimum tax that portion of dividends paid
by such Fund derived from interest on such bonds. Shareholders receiving Social
Security or certain other retirement payments should note that all
exempt-interest dividends will be taken into account in determining the
taxability of such benefits.

                  Interest on indebtedness incurred by a shareholder to purchase
or carry shares of the Michigan Municipal Bond Fund generally will not be
deductible for federal income tax purposes.

                                      -62-
<PAGE>   68

                  A taxable gain or loss may be realized by a shareholder upon
his or her redemption, transfer or exchange of Fund shares depending upon the
tax basis of such shares and their price at the time of redemption, transfer or
exchange. If a shareholder has held shares for six months or less and during
that time received a distribution taxable as a long-term capital gain, then any
loss the shareholder might realize on the sale of those shares will be treated
as a long-term loss to the extent of the earlier capital gain distribution.
Generally, a shareholder may include sales charges incurred upon the purchase of
Fund shares in his or her tax basis for such shares for the purpose of
determining gain or loss on a redemption, transfer or exchange of such shares.
However, if the shareholder effects an exchange of such shares for shares of
another Fund within 90 days of the purchase and is able to reduce the sales
charge applicable to the new shares (by virtue of the Trust's exchange
privilege), the amount equal to such reduction may not be included in the tax
basis of the shareholder's exchanged shares but may be included (subject to this
limitation) in the tax basis of the new shares.

MICHIGAN TAXES

                  Distributions by the Michigan Municipal Bond Fund to holders
of shares who are subject to the Michigan personal income tax and/or single
business tax will not be subject to the Michigan personal income tax, single
business tax or any Michigan city income tax to the extent that the
distributions are attributable to income received by the Fund as interest from
Michigan Municipal Securities or to the extent that the distributions are
attributable to interest income and gains from the sale or disposal of United
States obligations exempted from state taxation by the United States
Constitution, treaties, and statutes. However, some or all of the other
distributions by the Fund may be taxable by the State of Michigan or subject to
applicable city income taxes, even if the distributions are attributable to
income of the Fund derived from obligations of the United States or its agencies
and instrumentalities. In addition, to the extent that a shareholder of the
Municipal Bond Fund is obligated to pay state or local taxes outside of
Michigan, dividends earned by an investment in the Fund may represent taxable
income. Investments held in the Fund by a Michigan resident are not subject to
the Michigan intangible personal property tax to the extent that the investments
are attributable to bonds or other similar obligations of the State of Michigan
or a political subdivision thereof, or obligations of the United States.

                  The Michigan Department of Treasury in a 1986 Revenue
Administrative Bulletin has taken the position that the tax attributes of the
securities held by a mutual fund flow through to the investors. Based on this
position, the Michigan Department of Treasury has stated that mutual fund
distributions attributable to interest from a fund's investment in direct U.S.
government securities, as well as municipal securities, will not be subject to
the Michigan personal income tax. The Michigan Department of Treasury also has
stated that an owner of a share of a mutual fund will not be subject to
intangible personal property tax to the extent that the pro rata share of the
securities underlying the mutual fund would be exempt.

                  For Michigan personal income tax and intangible personal
property tax purposes, taxable distributions from investment income and
short-term capital gains, if any, are taxable as ordinary income, whether
received in cash or additional shares, and are subject to the Michigan
intangible personal property tax and to applicable Michigan city income taxes.
Business tax, a 



                                      -63-

modified value added tax, is computed by applying the tax rate to a tax base
determined by making certain adjustments to federal taxable income. Taxable
distributions from investment income and gains, if any, may be included in
federal taxable income or may comprise one of the adjustments made to the tax
base. Distributions of cash, other property or additional shares by the Michigan
Municipal Bond Fund to a Michigan single business taxpayer attributable to any
gain realized from the sale, exchange or other disposition of Michigan Municipal
Securities may be included in the Michigan single business taxpayer's adjusted
tax base for purposes of the Michigan single business tax to the extent included
in federal taxable income. Distributions of cash, other property or additional
shares by the Michigan Municipal Bond Fund to a Michigan single business
taxpayer are not subject to the Michigan single business tax to the extent that
the distributions are attributable to interest income from and any gain realized
from the sale, exchange or other disposition of U.S. securities. Taxable
long-term capital gain distributions are taxable as long-term capitals gains for
Michigan purposes irrespective of how long a shareholder has held the shares,
except that such distributions reinvested in shares of the Michigan Municipal
Bond Fund are exempt from the Michigan intangible personal property tax.

MISCELLANEOUS

                  Shareholders of the Funds will be advised at least annually as
to the federal income tax consequences and, in the case of the Michigan
Municipal Bond Fund, Michigan income tax consequences, of distributions made to
them each year. Shareholders are advised to consult their tax advisers
concerning the application of state and local taxes, other than Michigan taxes,
which may differ from federal tax consequences described above.

                  The foregoing discussion is based on tax laws and regulations
which were in effect as of the date of this Prospectus; such laws and
regulations may be changed by legislative or administrative actions. The
foregoing summarizes some of the important tax considerations generally
affecting the Funds and their shareholders and is not intended as a substitute
for careful tax planning. Accordingly, potential investors should consult their
tax advisers with specific reference to their own tax situation.


                             MANAGEMENT OF THE TRUST

BOARD OF TRUSTEES

                  The business and affairs of the Trust are managed under the
direction of the Trust's Board of Trustees. The trustees of the Trust, their
addresses, principal occupations during the past five years, other affiliations,
and the compensation paid by the Trust and the fees and reimbursed expenses they
receive in connection with each meeting of the Board of Trustees they attend are
included in the Statement of Additional Information.

INVESTMENT ADVISER

                  IMC serves as the investment adviser to the Funds. IMC is a
registered investment adviser and an indirect, wholly owned subsidiary of
National City Corporation 



                                      -64-
<PAGE>   70

("NCC"). On September 30, 1998, IMC had approximately $16.6 billion in assets
under management. The principal office of the Adviser is:

                             1900 East Ninth Street
                             Cleveland, Ohio 44114.

                  Subject to the general supervision of the Trust's Board of
Trustees and in accordance with each Fund's investment policies, the Adviser has
agreed to manage the Funds, make decisions with respect to and place orders for
all purchases and sales of each Fund's securities, and maintain each Fund's
records relating to such purchases and sales.

                  The Adviser manages the Funds, makes decisions with respect to
and places orders for all purchases and sales of each Fund's securities and
maintains each Fund's records relating to such purchases and sales. IMC utilizes
a team management approach with professionals working to ensure a disciplined
investment process designed to result in long-term performance consistent with
the Funds' investment objectives. No one person is responsible for a Fund's
management.

                  Mid Cap Growth Fund. IMC's Mid Cap Growth Style Team manages
the Mid Cap Growth Fund.

                  Aggressive Allocation and Conservative Allocation Funds. The
investment management teams within IMC share the management duties of these
Funds. Each team manages its respective segment allocation within the Funds,
according to its area of specialization.

                  U.S. Government Income and Michigan Municipal Bond Funds.
IMC's Fixed Income Team makes the investment decisions for the U.S. Government
Income and Michigan Municipal Bond Funds.

                  For the services provided and expenses assumed pursuant to the
Advisory Agreement relating to the Funds, the Adviser is entitled to receive an
advisory fee, computed daily and payable monthly, at the annual rate of .40%,
1.00% , 1.00%, 1.00%, .55% and .55% of the average net assets of the Treasury
Plus Money Market, Mid Cap Growth, Aggressive Allocation, Conservative
Allocation, U.S. Government Income and Michigan Municipal Bond Funds,
respectively. The Trust believes that the fees are within the range of fees
payable by investment funds with comparable investment objectives and policies.
The Adviser may from time to time waive all or a portion of their advisory fees
to increase the net income of the Funds available for distribution as dividends.

YEAR 2000 RISKS

                  Like other investment companies, financial and business
organizations and individuals around the world, the Funds could be adversely
affected if the computer systems used by the Adviser and a Fund's other service
providers do not properly process and calculate date-related information and
data from and after January 1, 2000. This is commonly known as the 



                                      -65-
<PAGE>   71

"Year 2000 Problem." The Adviser is taking steps to address the Year 2000
Problem with respect to the computer systems that it uses and to obtain
assurance that comparable steps are being taken by a Fund's other major service
providers. At this time, however, there can be no assurance that these steps
will be sufficient to avoid any adverse impact on a Fund as a result of the Year
2000 Problem.

ADMINISTRATOR AND SUB-ADMINISTRATOR

                  SEI Investments Mutual Funds Services (the "Administrator"),
located at One Freedom Valley Drive, Oaks, Pennsylvania 19456, serves as the
administrator to the Funds. The Administrator is an indirect, wholly-owned
subsidiary of SEI Investments Company ("SEI Investments").

                  Under its Administration Agreement with the Trust relating to
the Fund, the Administrator provides the Funds with administrative services,
including fund accounting, regulatory reporting, necessary office space,
equipment, personnel and facilities. The Administrator also acts as shareholder
servicing agent of the Funds. The Administrator is entitled to receive with
respect to the Trust an administrative fee, computed daily and paid monthly, at
the annual rate of .07% of the aggregate average daily net assets of all the
investment funds of the Trust up to the first $18 billion, and .06% of the
aggregate average daily net assets over $18 billion. In addition, the
Administrator is entitled to be reimbursed for its out-of-pocket expenses
incurred on behalf of the Funds.

                  IMC serves as Sub-Administrator for the Funds and provides
certain services as may be requested by the Administrator from time to time. For
its services as Sub-Administrator, IMC receives, from the Administrator,
pursuant to its Sub-Administration Agreement with the Administrator, a fee,
computed daily and paid monthly, at the annual rate of .01% of the aggregate
average daily net assets of all of the investment funds of the Trust up to the
first $15 billion, and .015% of the aggregate average daily net assets over $15
billion.

                     DESCRIPTION OF THE TRUST AND ITS SHARES

                           AA-Special Series 2)

                  Each share has no par value, represents an equal proportionate
interest in the investment fund with other shares of the same class or series
outstanding, and is entitled to such dividends and distributions out of the
income earned on the assets belonging to such Fund as are declared in the
discretion of the Trust's Board of Trustees. The Trust's Declaration of Trust
authorizes the Board of Trustees to classify or reclassify any unissued shares
into any number of additional classes of shares and to classify or reclassify
any class of shares into one or more series of shares.

                  Shareholders are entitled to one vote for each full share
held, and a proportionate fractional vote for each fractional share held.
Shareholders will vote in the aggregate and not by investment fund, except as
otherwise expressly required by law or when the Board of Trustees determines
that the matter to be voted on affects only the interests of shareholders of a
particular investment fund. The Statement of Additional Information gives
examples of situations in which the law requires voting by investment fund. In
addition, shareholders of each of the investment Funds will vote in the
aggregate and not by class or series, except as otherwise expressly required by
law or when the Board of Trustees determines the matter to be voted on 



                                      -68-
<PAGE>   74

affects only the interests of the holders of a particular class or series of
shares. Under the I and A Plan and B Shares Plan, only the holders of A and I
shares (with respect to the I and A Plan) or B shares (with respect to the B
Shares Plan) in an investment fund are, or would be entitled to vote on matters
submitted to a vote of shareholders (if any) concerning their respective plans.
Voting rights are not cumulative, and accordingly, the holders of more than 50%
of the aggregate shares of the Trust may elect all of the trustees irrespective
of the vote of the other shareholders.

                  As stated above, the Trust is organized as a trust under the
laws of Massachusetts. Shareholders of such a trust may, under certain
circumstances, be held personally liable (as if they were partners) for the
obligations of the trust. The Declaration of Trust of the Trust provides for
indemnification out of the trust property for 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 Trust does not presently intend to hold annual meetings of
shareholders except as required by the 1940 Act or other applicable law. The
Trust's Code of Regulations provides that special meetings of shareholders shall
be called at the written request of shareholders entitled to cast at least 10%
of the votes entitled to be cast at such meeting. Such meeting may be called by
shareholders to consider the removal of one or more trustees. Shareholders will
receive shareholder communication assistance with respect to such matter as
required by the 1940 Act.


                          CUSTODIAN AND TRANSFER AGENT

                   National City Bank, an affiliate of IMC, serves as the
custodian of the Trust's assets. With respect to each fund, the Trust pays
National City Bank an annual custody fee, calculated daily and paid monthly, of
 .02% of each fund's first $100 million of average daily net assets, .01% of each
fund's next $650 million of average daily net assets and .008% of the average
daily net assets of each fund which exceed $750 million, exclusive of
out-of-pocket expenses and transaction charges. The Trust reimburses the
custodian for its out-of-pocket expenses including, but not limited to, postage,
telephone, telex, interest claim fee ($50.00 per claim), transfer and
registration fees, Federal Express charges, Federal Reserve and wire fees, as
well as its out-of-pocket costs in providing any foreign custody services and/or
precious metal custody services. The transaction charges are a bundled fee which
will not exceed .25% of the total monthly asset based fee payable by the Trust.

                  State Street Bank and Trust Company serves as the Trust's
transfer and dividend disbursing agent. Communications to the Transfer Agent
should be directed to P.O. Box 8421, Boston, Massachusetts 02266-8421. The fees
payable by the Trust for these services are described in the Statement of
Additional Information.

                                    EXPENSES

                  Except as noted below, the Adviser bears all expenses in
connection with the performance of its services. Each Fund bears its own
expenses incurred in its operations including: taxes; interest; fees (including
fees paid to its trustees and officers); SEC fees; state securities
qualification fees; costs of preparing and printing prospectuses for regulatory
purposes and for distribution to existing shareholders; expenses related to the
distribution and servicing plans; advisory fees; administration fees and
expenses; charges of the custodian and Transfer Agent; certain insurance
premiums; outside auditing and legal expenses; costs of shareholders' reports
and shareholder meetings; and any extraordinary expenses. Each Fund also pays
for brokerage fees and commissions in connection with the purchase of its
portfolio securities.


                                  MISCELLANEOUS

                  Shareholders will receive unaudited semi-annual reports and
annual financial statements audited by independent auditors.

                  Pursuant to Rule 17f-2, since National City Bank serves the
Trust as its custodian and is affiliated with IMC, the Trust's investment
adviser, a procedure has been established requiring three annual verifications,
two of which are to be unannounced, of all investments held pursuant to the
Custodian Services Agreement, to be conducted by the Trust's independent
auditors.

                  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.

                  The portfolio managers of the Funds and other investment
professionals may from time to time discuss in advertising, sales literature or
other material, including periodic publications, various topics of interest to
shareholders and prospective investors. The topics may include, but are not
limited to, the advantages and disadvantages of investing in tax-deferred and
taxable investments; Fund performance and how such performance may compare to
various market indices; shareholder profiles and hypothetical investor
scenarios; the economy; the financial and capital markets; investment strategies
and techniques; investment products and tax, retirement and investment planning.

                  Inquiries regarding the Trust or any of its investment funds
may be directed to 1-800-622-FUND(3863).

                       STATEMENT OF ADDITIONAL INFORMATION
                       -----------------------------------

                  This Statement of Additional Information should be read in
conjunction with the Prospectus of Armada Funds (the "Trust") that describes the
Treasury Plus Money Market Fund, Mid Cap Growth Fund, Aggressive Allocation
Fund, Conservative Allocation Fund, U.S. Government Income Fund and Michigan
Municipal Bond Fund (collectively, the "Funds" and each, a "Fund"). The
information contained in this Statement of Additional Information expands upon
matters discussed in the Prospectus. No investment in shares of the Funds should
be made without first reading the Prospectus.


                      INVESTMENT OBJECTIVES AND POLICIES
                      ----------------------------------

ADDITIONAL INFORMATION ON FUND MANAGEMENT
- -----------------------------------------

                  Further information on the Adviser's investment management
strategies, techniques, policies and related matters may be included from time
to time in advertisements, sales literature, communications to shareholders and
other materials. See also "Yield and Performance Information" below.

                  Attached to this Statement of Additional Information is
Appendix A which contains descriptions of the rating symbols used by Standard &
Poor's Rating Group ("S&P"), Fitch IBCA, Inc. ("Fitch IBCA"), Duff & Phelps
Credit Rating Co. ("Duff"), and Moody's Investors Service, Inc. ("Moody's") for
securities which may be held by the Funds.

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

                  The Treasury Plus Money Market Fund 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 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 Treasury Plus
Money Market Fund 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.

FOREIGN SECURITIES
- ------------------

                  Unanticipated political or social developments may affect the
value of a Fund's investments in emerging market countries and the availability
to a Fund of additional investments in those countries. The small size,
relatively unseasoned nature of the securities markets and limited volume of
trading in securities in certain of these countries may make a Fund's
investments there illiquid and more volatile than investments in Japan or most
Western European countries. In addition, a Fund may be required to establish
special custodial or other arrangements before making certain investments.
Moreover, there may be little financial or accounting information available with
respect to issuers located in certain emerging market countries, and it may be
difficult as a result to assess the value or prospects of an investment in such
issuers.

FOREIGN GOVERNMENT OBLIGATIONS
- ------------------------------

                  The Mid Cap Growth, Aggressive Allocation and Conservative
Allocation 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 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 Mid Cap Growth, Aggressive Allocation, Conservative Allocation 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 a Fund 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, a Fund 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.

                  When the 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, a 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 a Fund's securities denominated in such foreign currency.
Similarly, when the obligations held by a Fund create a short position in a
foreign currency, a Fund 



                                      -3-
<PAGE>   83

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 cash or liquid securities
equal to the amount of a Fund's 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 Fund. A forward contract to sell a foreign currency is "covered" if a
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 a Fund
holds a forward contract (or call option) permitting the Fund to sell the same
currency at a price as high as or higher than the Fund's price to buy the
currency.

CONVERTIBLE SECURITIES
- ----------------------

                  The Mid Cap Growth, Aggressive Allocation and Conservative
Allocation Funds may invest in convertible securities. Convertible securities
entitle 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 for a Fund, the 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 a
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 will consider whether such issuers will
have sufficient cash 



                                      -4-
<PAGE>   84

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.

WARRANTS
- --------

                  The Mid Cap Growth, Aggressive Allocation and Conservative
Allocation 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 CONTRACTS AND RELATED OPTIONS
- -------------------------------------

                  The Mid Cap Growth, Aggressive Allocation, Conservative
Allocation and U.S. Government Income Funds may invest in futures contracts and
related options. For a detailed description of these investments and related
risks, see Appendix B attached to this Statement of Additional Information.

"COVERED CALL" OPTIONS
- ----------------------

                  As described in the Prospectus, the Mid Cap Growth, Aggressive
Allocation, Conservative Allocation, U.S. Government Income and Michigan
Municipal Bond Funds may write covered call options. A Fund will write call
options only if they are "covered." The option is "covered" if a Fund owns the
security underlying the call or has an absolute and immediate right to acquire
that security without additional cash consideration (or, if additional cash
consideration is required, liquid assets of equal value are held in a segregated
account by its custodian) upon conversion or exchange of other securities held
by it. For a call option on an index, the option is covered if a Fund maintains
with its custodian a portfolio of securities substantially replicating the
movement of the index, or liquid assets equal to the contract value. A call
option is also covered if a Fund holds a call on the same security or index as
the call written where the exercise price of the call held is (i) equal to or
less than the exercise price of the call written, or (ii) greater than the
exercise price of the call written provided the difference is maintained by a
Fund in liquid assets in a segregated account with its custodian.

                  A Fund's obligation to sell a security subject to a covered
call option written by it may be terminated prior to the expiration date of the
option by a Fund's execution of a closing purchase transaction, which is
effected by purchasing on an exchange an option of the same series (i.e., same
underlying security, exercise price and expiration date) as the option
previously written. Such a purchase does not result in the ownership of an
option. A closing purchase transaction will



                                      -5-
<PAGE>   85

ordinarily be effected to realize a profit on an outstanding option, to prevent
an underlying security from being called, to permit the sale of the underlying
security or to permit the writing of a new option containing different terms on
such underlying security. The cost of such a liquidation purchase plus
transaction costs may be greater than the premium received upon the original
option, in which event a Fund will have incurred a loss on the transaction.
There is no assurance that a liquid secondary market will exist for any
particular option. An option writer, unable to effect a closing purchase
transaction, will not be able to sell the underlying security until the option
expires or the optioned security is delivered upon exercise with the result that
the writer in such circumstances will be subject to the risk of market decline
or appreciation in the security during such period.

                  When a Fund writes an option, an amount equal to the net
premium (the premium less the commission) received by a Fund is included in the
liability section of a Fund's statement of assets and liabilities as a deferred
credit. The amount of this deferred credit will be subsequently marked-to-market
to reflect the current value of the option written. The current value of the
traded option is the last sale price or, in the absence of a sale, the current
bid price. If an option written by a Fund expires on the stipulated expiration
date or if a Fund enters into a closing purchase transaction, it will realize a
gain (or loss if the cost of a closing purchase transaction exceeds the net
premium received when the option is sold) and the deferred credit related to
such option will be eliminated. If an option written by a Fund is exercised, the
proceeds of the sale will be increased by the net premium originally received
and the Fund will realize a gain or loss.

                  There are several risks associated with transactions in
certain options. For example, there are significant differences between the
securities and options markets that could result in an imperfect correlation
between these markets, causing a given transaction not to achieve its
objectives. In addition, a liquid secondary market for particular options,
whether traded over-the-counter or on a securities exchange may be absent for
reasons which include the following: there may be insufficient trading interest
in certain options; restrictions may be imposed by an exchange on opening
transactions or closing transactions or both; trading halts, suspensions or
other restrictions may be imposed with respect to particular classes or series
of options or underlying securities or currencies; unusual or unforeseen
circumstances may interrupt normal operations on an exchange; the facilities of
an exchange or the Options Clearing Corporation may not at all times be adequate
to handle current trading volume; or one or more exchanges could, for economic
or other reasons, decide or be compelled at some future date to discontinue the
trading of options (or a particular class or series of options), in which event
the secondary market on that exchange (or in that class or series of options)
would cease to exist, although outstanding options that had been issued by the
Options Clearing Corporation as a result of trades on that exchange would
continue to be exercisable in accordance with their terms.

ASSET-BACKED SECURITIES
- -----------------------

                  As described in the Prospectus, the Aggressive Allocation,
Conservative Allocation and U.S. Government 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 



                                      -6-
<PAGE>   86

the securities are made periodically, thus in effect "passing through" periodic
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 a Fund may include collateralized
mortgage obligations ("CMOs") issued by private companies.

                  The Aggressive Allocation, Conservative Allocation, U.S.
Government Income and Michigan Municipal Bond Funds may invest in securities the
timely payment of principal and interest on which are guaranteed by the
Government National Mortgage Association ("GNMA") a wholly-owned U.S. Government
corporation within the Department of Housing and Urban Development. The market
value and interest yield of these 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 



                                      -7-
<PAGE>   87

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 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.

                  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 Aggressive Allocation, Conservative Allocation and U.S.
Government Income Funds may enter into interest rate or total return swaps. The
Aggressive Allocation and Conservative Allocation Funds may also enter into
total return swaps. A Fund expects to enter into these transactions for hedging
purposes and not for speculation. It 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 a 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.

                  A Fund will only enter into swaps on a net basis, (i.e., the
two payment streams are netted out, with a 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, each Fund and the 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 a Fund's
obligations over its entitlements with



                                      -8-
<PAGE>   88

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, a Fund 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.

INCOME PARTICIPATION LOANS
- --------------------------

                  The Aggressive Allocation and Conservative Allocation 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 a 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.

SHORT-TERM OBLIGATIONS
- ----------------------

                  The Mid Cap Growth, Aggressive Allocation, Conservative
Allocation and U.S. Government Income Funds may invest directly in various
short-term obligations including those described below.

                  Investments include commercial paper and other short-term
promissory notes issued by corporations (including variable and floating rate
instruments). The Mid Cap Growth, Aggressive Allocation and Conservative
Allocation 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. The Aggressive Allocation and Conservative Allocation Funds
may also invest in Europaper, which is U.S. dollar denominated commercial paper
of a foreign issuer. The Aggressive Allocation, Conservative Allocation and
Michigan Municipal Bond Funds



                                      -9-
<PAGE>   89

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
Aggressive Allocation, Conservative Allocation and Michigan Municipal Bond 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 Mid Cap Growth, Aggressive Allocation, Conservative
Allocation and U.S. Government Income 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 the 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 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 addition, because a 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% of the Fund's net assets.

WHEN-ISSUED SECURITIES
- ----------------------

                  The Mid Cap Growth, Aggressive Allocation, Conservative
Allocation, U.S. Government Income and Michigan Municipal Bond Funds may
purchase securities on a "when-issued" basis (i.e., for delivery beyond the
normal settlement date at a stated price and yield). 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 the 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 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.

                                      -10-
<PAGE>   90

                  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.

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

                  Securities held by each of the 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 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 a 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 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.

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

                  Each of the Funds may borrow funds for temporary purposes by
entering 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. Each 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 equal to the repurchase price (including accrued interest), and
will subsequently monitor the account to ensure that 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 a Fund under the Investment Company Act of 1940.

                                      -11-
<PAGE>   91

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

                  Each of the Mid Capitalization, Aggressive Allocation,
Conservative Allocation and U.S. Government Income Funds may lend securities
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. 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.

U.S. GOVERNMENT OBLIGATIONS
- ---------------------------

                  As described in the Prospectus, each of the Funds may purchase
obligations issued or guaranteed by the U.S. government, its agencies or
instrumentalities. 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.

VARIABLE AMOUNT MASTER DEMAND NOTES
- -----------------------------------

                  Variable amount master demand notes in which the Mid Cap
Growth, Aggressive Allocation, Conservative Allocation, U.S. Government Income
and Michigan Municipal Bond Funds may invest are unsecured demand notes that
permit the indebtedness thereunder to vary and provide for periodic adjustments
in the interest rate according to the terms of the instrument. Because master
demand notes are direct lending arrangements between a Fund and the issuer, they
are not normally traded. Although there is no secondary market in the notes, a
Fund may demand payment of principal and accrued interest at any time. While the
notes are not typically rated by credit rating agencies, issuers of variable
amount master demand notes (which are normally manufacturing, retail, financial,
and other business concerns) must satisfy the same criteria as set forth above
for commercial paper. The Adviser will consider the earning power, cash flow,
and other liquidity ratios of such notes and will continuously monitor the
financial 



                                      -12-
<PAGE>   92

status and ability to make payment on demand. In determining dollar average
maturity, a variable amount master demand note will be deemed to have a maturity
equal to the longer of the period of time remaining until the next interest rate
adjustment or the period of time remaining until the principal amount can be
recovered from the issuer through demand.

VARIABLE AND FLOATING RATE OBLIGATIONS
- --------------------------------------

                  The Mid Cap Growth, Aggressive Allocation, Conservative
Allocation, U.S. Government Income and Michigan Municipal Bond 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 a 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.

SECURITIES OF OTHER INVESTMENT COMPANIES
- ----------------------------------------

                  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 a 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 a Fund or by the Trust as a whole. 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 a Fund and, therefore,
will be borne indirectly by its shareholders.

MICHIGAN MUNICIPAL SECURITIES
- -----------------------------

         The assets of the Michigan Municipal Bond Fund will be invested in
obligations consisting of bonds, notes, commercial paper, and certificates of
indebtedness, issued by or on 



                                      -13-
<PAGE>   93

behalf of the State of Michigan, its political subdivisions, municipalities and
public authorities, the interest on which is exempt from federal income tax and
Michigan state income and intangibles taxes (but may be treated as a preference
item for purposes of the federal alternative minimum tax) and in 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 and intangible taxes ("Michigan
Municipal Securities"). Under normal market conditions, at least 80% of the net
assets of the Fund will be invested in Michigan Municipal Securities, and at
least 65% of the net assets of the Fund will be invested in Michigan Municipal
Securities issued by or on behalf of the State of Michigan, its political
subdivisions, municipalities and public authorities.

         Michigan Municipal Securities include debt obligations issued by
governmental entities to obtain funds for various public purposes, such as the
construction of a wide range of public facilities, the refunding of outstanding
obligations, the payment of general operating expenses, and the extension of
loans to other public institutions and facilities. Private activity bonds that
are issued by or on behalf of public authorities to finance various
privately-operated facilities are included within the term Michigan Municipal
Securities if the interest paid thereon is exempt from both federal and Michigan
state income and intangibles taxes although such interest may be treated as a
preference item for purposes of the federal alternative minimum tax.

         Other types of Michigan Municipal Securities which the Michigan
Municipal Bond Fund may purchase are short-term general obligation notes, tax
anticipation notes, bond anticipation notes, revenue anticipation notes,
tax-exempt commercial paper, construction loan notes and other forms of
short-term tax-exempt loans. Such instruments are issued with a short-term
maturity in anticipation of the receipt of tax funds, the proceeds of bond
placements or other revenues.

         The two principal classifications of Michigan Municipal Securities
consist of "general obligation" and "revenue" issues. The Michigan Municipal
Bond Fund may also acquire "moral obligation" issues, which are normally issued
by special purpose authorities. There are, of course, variations in the quality
of Michigan Municipal Securities, both within a particular classification and
between classifications, and the yields on Michigan Municipal Securities depend
upon a variety of factors, including general money market conditions, the
financial condition of the issuer, 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 a Rating Agency represent its opinion as
to the quality of Michigan Municipal Securities. It should be emphasized,
however, that ratings are general and are not absolute standards of quality, and
Michigan Municipal Securities with the same maturity, interest rate and rating
may have different yields, while Michigan Municipal Securities of the same
maturity and interest rate with different ratings may have the same yield.
Subsequent to purchase, an issue of Michigan Municipal Securities may cease to
be rated or its rating may be reduced below the minimum rating required for
purchase. The Adviser will consider such an event in determining whether the
Fund should continue to hold the obligation.

                                      -14-
<PAGE>   94

An issuer's obligations under Michigan 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, and laws, if any,
which may be enacted by Congress or state legislatures extending the time for
payment of principal or interest, or both, or imposing other constraints upon
the 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 on and principal of Michigan Municipal Securities may be
materially adversely affected by litigation or other conditions.


                  SPECIAL CONSIDERATIONS REGARDING INVESTMENT IN MICHIGAN
MUNICIPAL SECURITIES. The following information is drawn from various Michigan
governmental publications 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 1.5% in 1997. The rate of unemployment is estimated to have been 4.1%
in 1997, below the national average for the fourth consecutive year. Personal
income grew at an estimated 4.7% annual rate in 1997, up from the 4.2% growth
reported for 1996.

                  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, 1997 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 




                                      -15-
<PAGE>   95

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, 1997,
the State had approximately $677 million of general obligation bonds
outstanding.

                  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.

                  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.

                                      -16-
<PAGE>   96

                  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 activity bonds or other
"revenue" securities to make periodic payments for the use of those facilities.

OTHER TAX-EXEMPT INSTRUMENTS
- ----------------------------

                  Investments by the Michigan Municipal Bond Fund in tax-exempt
commercial paper will be limited to investments in obligations which are rated
at least A-2 by S&P, F-2 by Fitch IBCA or Prime-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 rate of interest is set as a
specific percentage of a designated base rate (such as the prime rate) at a
major commercial bank, and that the 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. The 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 long-term bond or 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.

STAND-BY COMMITMENTS
- --------------------

                  The Michigan Municipal Bond Fund may acquire stand-by
commitments (also known as put options) with respect to Michigan Municipal
Securities held in its portfolio. The Fund expects that stand-by commitments
will generally be available without the payment of any direct or indirect
consideration. However, if necessary or advisable, the Fund may pay for a
stand-by commitment either separately in cash or by paying a higher price for
portfolio securities which are acquired subject to the commitment (thus reducing
the yield to maturity otherwise available for the same securities). The Fund
will not acquire a stand-by commitment unless immediately after the acquisition,
not more than 5% of its total assets will be invested in instruments subject to
a demand feature, or in stand-by commitments, with the same institution.

                  The Fund's right to exercise stand-by commitments will be
unconditional and unqualified. A stand-by commitment will be transferable only
with the underlying Michigan



                                      -17-
<PAGE>   97

Municipal Securities which may be sold to a third party at any time. Until the
Fund exercises its stand-by commitment, it owns the securities in its portfolio
which are subject to the commitment.

                  The amount payable to the Fund upon its exercise of a stand-by
commitment will normally be (i) the Fund's acquisition cost of the Michigan
Municipal Securities (excluding any accrued interest which the Fund paid on its
acquisition), less any amortized market premium or plus any amortized market or
original issue discount during the period the Fund owned the securities, plus
(ii) all interest accrued on the securities since the last interest payment date
during that period. Under normal market conditions, in determining net asset
value, the Fund values the underlying Michigan Municipal Securities on an
amortized cost basis. Accordingly, the amount payable by a dealer upon exercise
of a stand-by commitment will normally be substantially the same as the
portfolio value of the underlying Michigan Municipal Securities.

                  The Fund intends to enter into stand-by commitments only with
dealers, banks and broker-dealers which, in the Adviser's opinion, present
minimal credit risks. The Fund's reliance upon the credit of these dealers,
banks and broker-dealers will be secured by the value of the underlying Michigan
Municipal Securities subject to the commitment. Thus, the risk of loss to the
Fund in connection with a stand-by commitment will not be qualitatively
different from the risk of loss faced by a person that is holding securities
pending settlement after having agreed to sell the securities in the ordinary
course of business.

PORTFOLIO TURNOVER
- ------------------

                  The portfolio turnover rate for each of the Funds is
calculated by dividing the lesser of a Fund's purchases or sales of portfolio
securities for the year by the monthly average value of the securities. The
Securities and Exchange Commission (the "SEC") requires that the calculation
exclude all securities whose remaining maturities at the time of acquisition are
one year or less.

                  Because the Treasury Plus Money Market Fund intends to invest
entirely in securities with maturities of less than one year and because the SEC
requires such securities to be excluded from the calculation of portfolio
turnover rate, the portfolio turnover rate with respect to the Treasury Plus
Money Market Fund is expected to be zero for regulatory purposes.

                  The portfolio turnover rates for the Funds 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, in the case of the Michigan
Municipal Bond Fund, by requirements which enable the Fund to receive certain
favorable tax treatments. With respect to the Conservative Allocation Fund, the
Adviser anticipates that the annual portfolio turnover rate may be as high as
200%. With respect to the Aggressive Allocation Fund, the Adviser anticipates
that the annual portfolio turnover rate may be as high as 200%. High portfolio
turnover rates will generally result in higher transaction costs to a Fund,
including brokerage commissions, and may result in additional tax consequences
to a Fund's shareholders. Portfolio turnover will not be a limiting factor in
making investment decisions.

                                      -18-
<PAGE>   98

                  For the U.S. Government Income Fund, changes in portfolio
turnover rates occurred in connection with changes in opportunities perceived by
the Adviser to be profitable to the Fund and its shareholders.

ADDITIONAL INVESTMENT LIMITATIONS
- ---------------------------------

                  In addition to the investment limitations disclosed in the
Prospectus, 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 a 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 a 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; and (c) purchase publicly traded securities of companies engaging in
whole or in part in such activities. For purposes of this investment limitation,
"commodities" will include commodity contracts.

                  3. Act as an underwriter of securities within the meaning of
the Securities Act of 1933 except insofar as a Fund might be deemed to be an
underwriter upon the disposition of portfolio securities acquired within the
limitation on purchases of illiquid 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, each Fund is 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 each 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 each
Fund's investment objective and policies, (a)



                                      -19-
<PAGE>   99

this investment limitation shall not apply to a Fund's transactions in futures
contracts and related options, options on securities or indices of securities
and similar instruments, and (b) a Fund 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% for the Treasury Plus Money
Market Fund) of its net assets in illiquid securities.

                  A Fund does not intend to purchase securities while its
outstanding borrowings (including reverse repurchase agreements) are in excess
of 5% of its assets. Securities held in escrow or in separate accounts in
connection with a Fund's investment practices are not deemed to be pledged for
purposes of this limitation.

                  With respect to the Michigan Municipal Bond Fund, 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).


              NET ASSET VALUE - TREASURY PLUS MONEY MARKET FUND
              -------------------------------------------------

                  The Trust uses the amortized cost method to value shares in
the Treasury Plus Money Market Fund. 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 the Fund would receive if it sold the security. The value of the
portfolio securities held by the 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 Treasury Plus Money Market Fund invests 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 the 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 



                                      -20-
<PAGE>   100

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 the 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 the 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 the 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 the Fund's
outstanding shares without monetary consideration; or utilizing a net asset
value per share determined by using available market quotations.


                   DIVIDENDS - TREASURY PLUS MONEY MARKET FUND
                   -------------------------------------------

                  As stated, the Trust uses its best efforts to maintain the net
asset value per share of the Treasury Plus Money Market Fund at $1.00. As a
result of a significant expense or realized or unrealized loss incurred by the
Fund, it is possible that the 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
the Fund for a particular period, the Board of Trustees would at that time
consider whether to adhere to the present dividend policy with respect to the
Fund 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. Such
expense or loss may result in a shareholder's receiving no dividends for the
period in which he or she holds shares of the 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. 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.

                                      -21-
<PAGE>   101

                  As stated in the Prospectus, the public offering price of A
shares of the Treasury Plus Money Market Fund is its net asset value per share
which it will seek to maintain at $1.00. 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 shares of the Funds are sold
to certain qualified investors at their net asset value without a sales charge.
A shares of the Funds are sold to public investors at the public offering price
based on a Fund's net asset value plus a front-end load or sales charge as
described in the Prospectus. B shares of the Funds 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.

                  Automatic investment programs such as the Planned Investment
Program ("PIP") described in the Prospectus offered by the Funds permit an
investor to use "dollar cost averaging" in making investments. Through PIP, 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 PIP 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.

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 the
Fund's 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 to act on telephonic 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 



                                      -22-
<PAGE>   102

Agent of his or her prior ownership of A 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
setting or changing in any one or more respects their respective preferences,
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
or series of shares set forth in the Prospectus, including seventeen classes or
series, which represent interests in the Treasury Plus Money Market, U.S.
Government Income, Aggressive Allocation, Conservative Allocation, Mid Cap
Growth and Michigan Municipal Bond Funds (Class CC, Class CC - Special Series 1,
Class DD, Class DD - Special Series 1, Class DD - Special Series 2, Class EE,
Class EE Special Series 1, Class EE - Special Series 2, Class FF, Class FF -
Special Series 1, Class FF - Special Series 2, Class GG, Class GG - Special
Series 1, Class GG - Special Series 2, Class HH, Class HH - Special Series 1 and
Class HH - Special Series 2) are 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, 



                                      -23-
<PAGE>   103

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 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 will be treated as a separate corporate entity under
the Code and each Fund intends to qualify as a regulated investment company. In
order to qualify for tax treatment as a regulated investment company under the
Code, each 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 each 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 a 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 a Fund's principal business of investing in stock or
securities, or options and futures with respect to stock or securities. Any
income derived by a Fund from a partnership or trust is treated as derived with


                                      -24-
<PAGE>   104

respect to a 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 a Fund in the same manner as by
the partnership or trust.

                  Some investments held by a Fund may be subject to special
rules which govern the federal income tax treatment of certain transactions
denominated in terms of a currency other than the U.S. dollar or determined by
reference to the value of one or more currencies other than the U.S. dollar. The
types of transactions covered by the special rules include the following: (1)
the acquisition of, or becoming the obligor under, a bond or other debt
instrument (including, to the extent provided in Treasury regulations, preferred
stock); (2) the accruing of certain trade receivables and payables; and (3) the
entering into or acquisition of any forward contract, futures contract, option
and similar financial instrument. The disposition of a currency other than the
U.S. dollar by a U.S. taxpayer is also treated as a transaction subject to the
special currency rules. With respect to transactions covered by the special
rules, foreign currency gain or loss is calculated separately from any gain or
loss on the underlying transaction and is normally taxable as ordinary gain or
loss. The Treasury Department has issued regulations under which certain
transactions subject to the special currency rules that are part of a "section
988 hedging transaction" are not subject to the mark-to-market or loss deferral
rules under the Code. Gain or loss attributable to the foreign currency
component of transactions engaged in by a Fund which are not subject to the
special currency rules (such as foreign equity investments other than certain
preferred stocks) will be treated as capital gain or loss and will not be
segregated from the gain or loss on the underlying transaction.

                  The Trust will designate any distribution of long-term capital
gains of a Fund as a capital gain dividend in a written notice mailed to
shareholders within 60 days after the close of the Trust's taxable year.
Shareholders should note that, upon the sale or exchange of Fund shares, if the
shareholder has not held such shares for at least six months, any loss on the
sale or exchange of those shares will be treated as long-term capital loss to
the extent of the capital gain dividends received with respect to the shares.

                  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). The Funds intend 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.

                  If for any taxable year a 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 a Fund's shareholders to the extent of a
Fund's current and accumulated earnings and profits, and would be eligible for
the dividends received deduction for corporations.

                                      -25-
<PAGE>   105

                  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."

                  Depending upon the extent of a Fund's 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, such Fund may be subject to the tax laws of such states or
localities. In addition, in those states and localities which have income tax
laws, the treatment of a Fund and its shareholders under such laws may differ
from their treatment under federal income tax laws. Under state or local law,
distributions of net investment income may be taxable to shareholders as
dividend income even though a substantial portion of such distributions may be
derived from interest on U.S. Government obligations which, if realized
directly, would be exempt from such income taxes. Shareholders are advised to
consult their tax advisers concerning the application of state and local taxes.

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, 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 



                                      -26-
<PAGE>   106

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.

         Under the Code, dividends attributable to interest on certain private
activity bonds issued after August 7, 1986, must be included in alternative
minimum taxable income for the purpose of determining liability (if any) for the
24% alternative minimum tax for individuals and the 20% alternative minimum tax
for corporations. These private activity bonds include: certain bonds issued to
obtain funds to provide certain water, sewage and solid waste facilities,
qualified residential rental projects, certain local electric, gas and other
heating or cooling facilities, qualified hazardous waste facilities, and
government-owned airports, docks and wharves and mass commuting facilities;
certain qualified mortgage, student loan and redevelopment bonds; and certain
bonds issued as part of "small issues" for industrial facilities. In the case of
corporations, alternative minimum taxable income will also include an item of
tax preference consisting of 75% of the excess of the corporation's "adjusted
current earnings" over the corporation's other alternative minimum taxable
income, and for this purpose all tax-exempt interest dividends will be included
in the corporation's "adjusted current earnings." In addition, tax-exempt
interest dividends paid to corporate investors may be subject to an
environmental tax which is imposed at the rate of 0.12% on the excess of the
modified alternative minimum taxable income of a corporation over $2 million.

         While the Michigan Municipal Bond Fund does not expect to earn any
investment company taxable income, taxable income earned by the Fund will be
distributed. In general, the investment company taxable income will be the
taxable income of the Fund (for example, short-term capital gains) subject to
certain adjustments and excluding the excess of any net long-term capital gains
for the taxable year over the net short-term capital loss, if any, for such
year. The Fund would be taxed on any undistributed investment company taxable
income. Since any such income will be distributed, it will be taxable to
shareholders as ordinary income (whether paid in cash or additional shares).
While the Fund does not expect to realize long-term capital gains, any net
realized long-term capital gains will be distributed annually. The Fund will
have no federal tax liability and will have no state tax liability with respect
to such gains and the distributions will be taxable to shareholders as long-term
capital gains regardless of how long a shareholder has held the Fund's shares.
Such distributions will be designated as a capital gains dividend in a written
notice mailed by the Fund to shareholders after the close of the Fund's taxable
year.

         As indicated in the Prospectus, the Michigan Municipal Bond Fund may
acquire rights regarding specified portfolio securities under puts. The policy
of the Fund is to limit its acquisition of puts to those under which it will be
treated for federal income tax purposes as the owner of the securities acquired
subject to the put and the interest on such securities will be tax-exempt to it.
The Internal Revenue Service has issued a published ruling that provides some
guidance regarding the tax consequences of the purchase of puts that the Fund
could acquire 



                                      -27-
<PAGE>   107

under the 1940 Act. Although the Fund will only acquire a put after concluding
that it will have the tax consequences described above, the Internal Revenue
Service could reach a different conclusion.

         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.

         Income itself exempt from federal income taxation may be considered in
addition to taxable income when determining whether social security payments
received by a shareholder are subject to federal income taxation.

         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 or intangible taxes 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.

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

- -------------
*        The "Fund Complex" consists of Armada Funds, The Parkstone Group of
         Funds and The Parkstone Advantage Fund. 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.

**       Messrs. Benua and Tullis resigned as Trustees effective July 17, 1997
         and November 19, 1997, respectively.

***      Messrs. Farling, Gherlein and Martens became Trustees as of November
         19, 1997, July 17, 1997 and November 19, 1997, respectively.

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.

ADVISORY AGREEMENTS
- -------------------

                  IMC serves as investment adviser to the Funds under an
Advisory Agreement dated August 5, 1998. The Adviser is an affiliate of National
City Corporation, a bank holding company with $81 billion in assets, and
headquarters in Cleveland, Ohio and nearly 1,000 branch offices in six states.
From time to time, the Adviser may voluntarily waive fees or reimburse the Trust
for expenses.

                  The Advisory Agreement provides that the Adviser shall not be
liable for any error of judgment or mistake of law or for any loss suffered by
the Trust in connection with the performance of the Advisory Agreement, except a
loss resulting from a breach of fiduciary duty with respect to the receipt of
compensation for services or a loss resulting from willful misfeasance, bad
faith or gross negligence on the part of the Adviser in the performance of its
duties or from reckless disregard by the Adviser of its duties and obligations
thereunder.

                  The Advisory Agreement with IMC was approved by the sole
shareholder of each Fund on the date it commenced operations. Unless sooner
terminated, the Advisory Agreement 



                                      -33-
<PAGE>   113

will continue in effect with respect to the Funds until September 30, 1999 and
from year to year thereafter, subject to annual approval by the Trust's Board of
Trustees, or by a vote of a majority of the outstanding shares of the Funds (as
defined in the Fund's 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 Agreement may be terminated by the Trust or the Advisers on 60 days
written notice, and will terminate immediately in the event of its assignment.

ADMINISTRATION AGREEMENT AND SUB-ADMINISTRATION AGREEMENT
- ---------------------------------------------------------

                  The Trust and SEI Investments Mutual Funds Services (the
"Administrator") have entered into an administration agreement (the
"Administration Agreement") effective May 1, 1998.

                  The Administration Agreement provides that the Administrator
shall not be liable for any error of judgment or mistake of law or for any loss
suffered by the Trust in connection with the matters to which the Administration
Agreement relates, except a loss resulting from willful misfeasance, bad faith
or negligence on the part of the Administrator in the performance of its duties
or from reckless disregard by it of its duties and obligations thereunder.

                  The Administrator, a Delaware business trust, has its
principal business offices at One Freedom Valley Drive, Oaks, Pennsylvania
19456. SEI Investments Management Corporation ("SIMC"), a wholly-owned
subsidiary of SEI Investments Company ("SEI Investments"), is the owner of all
beneficial interests in the Administrator. SEI Investments and its affiliates,
including the Administrator, are leading providers of fund evaluation services,
trust accounting systems, and brokerage and information services to financial
institutions, institutional investors, and money managers. The Administrator and
its affiliates also serve as administrator or sub-administrator to the following
other mutual funds: The Achievement Funds Trust, The Advisors' Inner Circle
Fund, The Arbor Fund, ARK Funds, Bishop Street Funds, Boston 1784 Funds(R),
CrestFunds, Inc., CUFUND, The Expedition Funds, First American Funds, Inc.,
First American Investment Funds, Inc., First American Strategy Funds, Inc.,
HighMark Funds, Monitor Funds, Morgan Grenfell Investment Trust, Oak Associates
Funds, The PBHG Funds, Inc., PBHG Advisor Funds, Inc., PBHG Insurance Series
Fund, Inc., The Pillar Funds, SEI Asset Allocation Trust, SEI Daily Income
Trust, SEI Index Funds, SEI Institutional Investments Trust, SEI Institutional
Managed Trust, SEI Liquid Asset Trust, SEI Tax Exempt Trust, STI Classic Funds,
STI Classic Variable Trust, TIP Funds and TIP Institutional Funds.

                  The Administrator is entitled to receive with respect to the
Funds, an administrative fee, computed daily and paid monthly, at an annual rate
of .07% of the aggregate average daily net assets of all of the investment funds
of Armada up to the first eighteen (18) billion dollars in assets, and .06% of
the aggregate average daily net assets of over eighteen (18) billion dollars in
assets, and is entitled to be reimbursed for its out-of-pocket expenses incurred
on behalf of the Funds.

                  IMC serves as sub-administrator for the Funds and provides
certain services as may be requested by the Administrator from time to time. For
its services as Sub-Administrator, IMC receives, from the Administrator,
pursuant to its Sub-Administration Agreement with the 

                                      -34-
<PAGE>   114

Administrator, a fee, computed daily and paid monthly, at the annual rate of
 .01% of the aggregate average daily net assets of all of the investment funds of
Armada up to the first $15 billion, and .015% of the aggregate average daily net
assets over $15 billion.

DISTRIBUTION PLANS AND RELATED AGREEMENT
- ----------------------------------------

                  The Distributor acts as distributor of each 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 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
the 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 

                                      -35-

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.

                  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 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.

CUSTODIAN SERVICES AND TRANSFER AGENCY AGREEMENTS
- -------------------------------------------------

                  National City Bank serves as the Trust's custodian with
respect to the Funds. Under its Custodian Services Agreement, National City Bank
has agreed to: (i) maintain a separate account or accounts in the name of each
Fund; (ii) hold and disburse portfolio securities on account of the Funds; (iii)
collect and make disbursements of money on behalf of the Funds; (iv) collect and
receive all income and other payments and distributions on account of each
Fund's portfolio securities; (v) respond to correspondence by security brokers
and others relating to its duties; and (vi) make periodic reports to the Board
of Trustees concerning each Fund's operations. National City Bank is authorized
to select one or more banks or trust companies to serve as sub-custodian on
behalf of the Funds, provided that it shall remain responsible for the
performance of all of its duties under the Custodian Services Agreement and
shall hold the Funds harmless from the acts and omissions of any bank or trust
company serving as sub-custodian.

                  State Street Bank and Trust Company (the "Transfer Agent")
serves as the Trust's transfer agent and dividend disbursing agent with respect
to the Funds. Under its Transfer Agency Agreement, it has agreed to: (i) issue
and redeem shares of the Funds; (ii) transmit all communications by the Funds to
its shareholders of record, including reports to shareholders, dividend and
distribution notices and proxy materials for meetings of shareholders; (iii)
respond to correspondence by security brokers and others relating to its duties;
(iv) maintain shareholder accounts; and (v) make periodic reports to the Board
of Trustees concerning each Fund's operations. The Transfer Agent sends each
shareholder of record a monthly statement showing the total number of shares
owned as of the last business day of the month (as well as the dividends paid
during the current month and year), and provides each shareholder of record with
a daily transaction report for each day on which a transaction occurs in the
shareholder's account with a Fund.


                           SHAREHOLDER SERVICES PLANS
                           --------------------------

                  As stated in the Prospectus, the Trust has implemented the
Shareholder Services Plan for A shares and the B Shares Plan for each Fund's
shares. Pursuant to these plans, the Trust may enter into agreements with
financial institutions pertaining to the provision of administrative services to

                             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 Funds. The 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.

                  While the 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 Funds. 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 Funds. Such
information may be useful to the Adviser in serving both the Trust and other
clients, and, similarly, supplemental information obtained by the 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, a Fund will not give preference to its
Adviser's correspondents with respect to such transactions, securities, savings
deposits, repurchase agreements and reverse repurchase agreements.

<PAGE>   117


                  Investment decisions for the Funds 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 Funds. When a purchase or
sale of the same security is made at substantially the same time on behalf of
the Funds 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 Funds and such other
investment company or account. In some instances, this investment procedure may
adversely affect the price paid or received by the Funds or the size of the
position obtained or sold by the Funds. 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 Funds with those to be
sold or purchased for other investment companies or advisory clients.


                                    AUDITORS
                                    --------

                  Ernst & Young LLP, independent auditors, with offices at Two
Commerce Square, 2001 Market Street, Suite 4000, Philadelphia, Pennsylvania
19103, serve as independent auditors of the Trust.


                                     COUNSEL
                                     -------

                  Drinker Biddle & Reath LLP (of which Mr. McConnel, Secretary
of the Trust, is a partner), with offices at 1345 Chestnut Street, Philadelphia,
Pennsylvania 19107, are counsel to the Trust and will pass upon the legality of
the shares offered hereby.


                        YIELD AND PERFORMANCE INFORMATION
                        ---------------------------------

                  A Fund's "yield" as described in the Prospectus is calculated
according to formulas prescribed by the SEC. The standardized seven-day yield
for a class of Treasury Plus Money Market Fund shares is computed by determining
the net change, exclusive of capital changes and income other than investment
income, 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 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 Treasury Plus Money Market
Fund shares is computed by compounding the unannualized base 

                                      -38-
<PAGE>   118

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 Michigan Municipal Bond Fund's "tax-equivalent yield" is
computed by dividing the portion of the Fund's yield (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
Fund's yield that is not exempt from federal income tax.

                  The current yield for each class of shares in the Treasury
Plus Money Market 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 Treasury Plus
Money Market Fund's expenses and the types of instruments held by the Fund.

                  The "yield" for each of the Mid Cap Growth, Aggressive
Allocation, Conservative Allocation, U.S. Government Income and Michigan
Municipal Bond Funds described in the Prospectus is calculated by dividing each
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. Each 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(6)
                                    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.

                  Each of the Mid Cap Growth, Aggressive Allocation,
Conservative Allocation, U.S. Government Income and Michigan Municipal Bond
Funds calculate interest earned on debt obligations held in its portfolio 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

                                      -39-
<PAGE>   119

30-day period that the obligation is in the respective 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 a 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-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.

                  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.

                  Expenses accrued for the period (variable "b" in the formula)
include all recurring fees charged by a 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.

                  Each of the Mid Cap Growth, Aggressive Allocation,
Conservative Allocation, U.S. Government Income and Michigan Municipal Bond
Funds 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(1/n)
                               T = [(-----) - 1]
                                       P

                                      -40-
<PAGE>   120

   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 of the Mid Cap Growth, Aggressive Allocation,
Conservative Allocation, U.S. Government Income and Michigan Municipal Bond
Funds computes its aggregate total return 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 respective 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.

                  Each of the Mid Cap Growth, Aggressive Allocation,
Conservative Allocation, U.S. Government Income and Michigan Municipal Bond
Funds 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 reinvestment date, (2) all
recurring fees charged to all shareholder accounts are included, and (3) for

                                      -41-
<PAGE>   121

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 Mid Cap Growth, Aggressive Allocation, Conservative
Allocation, U.S. Government Income and Michigan Municipal Bond Funds may 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 a 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, a 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. Each Fund does not, for these purposes, deduct
from the initial value invested or the ending value redeemed any amount
representing sales charges. A 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 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, 

                                      -42-

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.

                                  -------------

                  The Trust bears all costs in connection with its organization,
including the fees and expenses of registering and qualifying its shares for
distribution under federal and state securities regulations. All organization
expenses are recorded as expenses as incurred in accordance with generally
accepted accounting principles.

                  As used in the Prospectus, "assets belonging to the Fund"
means the consideration received by the Trust upon the issuance of shares in
that Fund, together with all income, earnings, profits, and proceeds derived
from the investment thereof, including any proceeds from the sale of such
investments, any funds or payments derived from any reinvestment of such
proceeds, and a portion of any general assets of the Trust not belonging to the
Fund. In determining a Fund's net asset value, assets belonging to the Fund are
charged with the liabilities in respect of that Fund.

                                   ----------


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>   124

                  "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. The "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 symbol is attached to the ratings of instruments
with significant noncredit risks. It highlights risks to principal or volatility
of expected returns which are not addressed in the credit rating. Examples
include: obligations linked or indexed to equities, commodities, or currencies;
obligations exposed to severe prepayment risk, such as interest only and
principal-only mortgage securities; and obligations with unusually risking
interest terms, such as inverse floaters.

         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 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 operating 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.

                  Note: Moody's applies numerical modifiers 1, 2 and 3 in each
generic rating classification from "Aa" through "Caa." The modifier 1 indicates
that the obligation ranks in the higher end of its generic rating category; the
modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking
in the lower end of its generic rating category.

                  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 in periods of greater 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 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 IBCA for
corporate and municipal bonds:

                  "AAA" - Bonds considered to be investment grade and of the
highest credit quality. These ratings denote the lowest expectation of credit
risk and are assigned only in case of exceptionally strong capacity for timely
payment of financial commitments. This capacity is highly unlikely to be
adversely affected by foreseeable events.

                  "AA" - Bonds considered to be investment grade and of very
high credit quality. These ratings denote a very low expectation of credit risk
and indicate very strong capacity for timely payment of financial commitments.
This capacity is not significantly vulnerable to foreseeable events.

                  "A" - Bonds considered to be investment grade and of high
credit quality. These ratings denote a low expectation of credit risk and
indicate strong capacity for timely payment of financial commitments. This
capacity may, nevertheless, be more vulnerable to changes in circumstances or in
economic conditions than is the case for higher ratings.

                  "BBB" - Bonds considered to be investment grade and of good
credit quality. These ratings denote that there is currently a low expectation
of credit risk. The capacity for timely payment of financial commitments is
considered adequate, but adverse changes in circumstances and in economic
conditions are more likely to impair this capacity.

                  "BB" - Bonds considered to be speculative. These ratings
indicate that there is a possibility of credit risk developing, particularly as
the result of adverse economic changes over time; however, business or financial
alternatives may be available to allow financial commitments to be met.
Securities rated in this category are not investment grade.

                  "B" - Bonds are considered highly speculative. These ratings
indicate that significant credit risk is present, but a limited margin of safety
remains. Financial commitments are currently being met; however, capacity for
continued payment is contingent upon a sustained, favorable business and
economic environment.

                  "CCC", "CC", "C" - Bonds have high default risk. Default is a
real possibility, and capacity for meeting financial commitments is solely
reliant upon sustained, favorable business or economic developments. "CC"
ratings indicate that default of some kind appears probable, and "C" ratings
signal imminent default.

                  "DDD," "DD" and "D" - Bonds are in default. Securities are not
meeting obligations and are extremely speculative. "DDD" designates the highest
potential for recovery of amounts outstanding on any securities involved and "D"
represents the lowest potential for recovery.

                  To provide more detailed indications of credit quality, the
Fitch IBCA ratings from and including "AA" to "B" may be modified by the
addition of a plus (+) or minus (-) sign to show relative standing within these
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-5
<PAGE>   128

                  "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, 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 S&P 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-6
<PAGE>   129

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-7
<PAGE>   130

                  "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 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.

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 that are 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 margins of protection.

                  Fitch IBCA and Duff & Phelps use the short-term ratings
described under Commercial Paper Ratings for municipal notes.

                                   APPENDIX B
                                   ----------

                  As stated in the Prospectus, the Mid Cap Growth Fund,
Aggressive Allocation Fund, Conservative Allocation Fund and U.S. Government
Income Fund (the "Funds") may enter into certain futures transactions and
options for hedging purposes. Such transactions are described in this Appendix.

I. 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 Funds 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 Funds presently could accomplish a similar result to that
which each Fund 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 Funds, through using
futures contracts.

                  DESCRIPTION OF INTEREST RATE FUTURES CONTRACTS. An interest
rate futures contract sale would create an obligation by a 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 a 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 a 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 realizes
a 

                                      B-1
<PAGE>   133

loss. Similarly, the closing out of a futures contract purchase is effected by
a 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
Funds 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 Funds 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. A 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 Funds 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 an
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.

                                      B-2
<PAGE>   134

                  EXAMPLE OF FUTURES CONTRACT PURCHASE. A 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 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. A 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 a 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 a 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 a 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.

II. 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 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.

                  A 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. A Fund may do so either to hedge the value of its portfolio 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 index
futures contracts in anticipation of purchases of securities. In a substantial
majority of these transactions, a Fund will purchase such securities upon
termination of the long futures position, but long futures position may be
terminated without a corresponding purchase of securities.

                  In addition, a Fund may utilize index futures contracts in
anticipation of changes in the composition of its fund holdings. For example, in
the event that a 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 Funds 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.


III. FUTURES CONTRACTS ON FOREIGN CURRENCIES.

                  A futures contract on foreign currency creates a binding
obligation on one party to deliver, and a corresponding obligation on another
party to accept delivery of, a stated quantity of a foreign currency, for an
amount fixed in U.S. dollars. Foreign currency futures may be used by a Fund to
hedge against exposure to fluctuations in exchange rates between the U.S. dollar
and other currencies arising from multinational transactions.

IV. MARGIN PAYMENTS

                  Unlike when a Fund purchase or sells a security, no price is
paid or received by a Fund upon the purchase or sale of a futures contract.
Initially, a 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, the value of which may vary but is generally equal to 10% of less
of the value of the contract. This amount is known as initial margin. 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 a 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 instrument fluctuates making the long
and short positions in the futures contract more or less valuable, a process
known as "marking-to-market". For example, when a 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 a Fund has purchased a futures
contract and the price of the futures 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.


V. RISKS OF TRANSACTIONS IN FUTURES CONTRACTS

                  There are several risks in connection with the use of futures
by a 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, a 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,
a 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, a 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, a 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

                                      B-5
<PAGE>   137

such time period of the futures contract being used, or if otherwise deemed to
be appropriate by the Adviser. It is also possible that, where a Fund has sold
futures to hedge its portfolio against a decline in the market, the market may
advance and the value of securities held by the Fund may decline. If this
occurred, the Fund would lose money on the futures and also experience a decline
in value of its portfolio securities.

                  Where futures are purchased to hedge against a possible
increase in the price of securities or a currency before a Fund is able to
invest its cash (or cash equivalents) in securities (or options) in an orderly
fashion, it is possible that the market may decline instead; if a Fund then
concludes not to invest in securities or options 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 rate movements by the Adviser 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
Funds intend 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 Funds would continue to be required to make daily cash
payments of variation margin. However, in the event futures contracts have been
used to hedge portfolio 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.

                                      B-6
<PAGE>   138

                  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 Funds is also subject to the
Adviser's ability to predict correctly movements in the direction of the market.
For example, if a 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 a 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. A Fund may have to sell
securities at a time when it may be disadvantageous to do so.


VI. OPTIONS ON FUTURES CONTRACTS

                  The Funds 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 Funds 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 

                                      B-7
<PAGE>   139

put options on futures contracts may frequently involve less potential risk to
the Funds 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.

VII. OTHER MATTERS

                  Accounting for futures contracts will be in accordance with
generally accepted accounting principles.

                  reckless disregard of duty, or the matter of bad faith had
                  been adjudicated, it would in the opinion of such counsel have
                  been adjudicated in favor of such person. The rights accruing
                  to any person under these provisions shall not exclude any
                  other right to which he may be lawfully entitled, provided
                  that no person may satisfy any right of indemnity or
                  reimbursement hereunder except out of the property of the
                  Trust. The Trustees may make advance payments in connection
                  with the indemnification under this Section 9.3, provided that
                  the indemnified person shall have provided a secured written
                  undertaking to reimburse the Trust in the event it is
                  subsequently determined that he is not entitled to such
                  indemnification.

                  The Trustees shall indemnify representatives and employees of
                  the Trust to the same extent that Trustees are entitled to
                  indemnification pursuant to this Section 9.3.

                  Section 12 of Registrant's Custodian Services Agreement
                  provides as follows:

                  12. INDEMNIFICATION. The Trust, on behalf of each of the
                  Funds, agrees to indemnify and hold harmless the Custodian and
                  its nominees from all taxes, charges, expenses, assessments,
                  claims and liabilities (including, without limitation,
                  liabilities arising under the 1933 Act, the 1934 Act, the 1940
                  Act, the CEA, and any state and foreign securities and blue
                  sky laws, and amendments thereto), and expenses, including
                  (without limitation) reasonable attorneys' fees and
                  disbursements, arising directly or indirectly from any action
                  which the Custodian takes or does not take (i) at the request
                  or on the direction of or in reliance on the advice of the
                  Fund or (ii) upon Oral or Written Instructions. Neither the
                  Custodian, nor any of its nominees, shall be indemnified
                  against any liability to the Trust or to its shareholders (or
                  any expenses incident to such liability) arising out of the
                  Custodian's or its nominees' own willful misfeasance, bad
                  faith, negligence or reckless disregard of its duties and
                  obligations under this Agreement.

                  In the event of any advance of cash for any purpose made by
                  the Custodian resulting from Oral or Written Instructions of
                  the Trust, or in the event that the Custodian or its

                  nominee shall incur or be assessed any taxes, charges,
                  expenses, assessments, claims or liabilities in respect of the
                  Trust or any Fund in connection with the performance of this
                  Agreement, except such as may arise from its or its nominee's
                  own negligent action, negligent failure to act or willful
                  misconduct, any Property at any time held for the account of
                  the relevant Fund or the Trust shall be security therefor.

                  Section 6 of Registrant's Transfer Agency Agreement provides
                  as follows:

                  6.       Indemnification
                           ---------------

                  6.1      The Bank shall not be responsible for, and the Fund
                           shall on behalf of the applicable Portfolio indemnify
                           and hold the Bank harmless from and against, any and
                           all losses, damages, costs, charges, counsel fees,
                           payments, expenses and liability arising out of or
                           attributable to:

                           (a)      All actions of the Bank or its agents or

                                    to this Agreement, provided that such
                                    actions are taken in good faith and without
                                    negligence or willful misconduct.

                           (b)      The Fund's lack of good faith, negligence or
                                    willful misconduct which arise out of the
                                    breach of any representation or warranty of
                                    the Fund hereunder.

                           (c)      The reliance on or use by the Bank or its
                                    agents or subcontractors of information,
                                    records, documents or services which (i) are
                                    received by the Bank or its agents or
                                    subcontractors, and (ii) have been prepared,
                                    maintained or performed by the Fund or any
                                    other person or firm on behalf of the Fund
                                    including but not limited to any previous
                                    transfer agent or registrar.

                           (d)      The reliance on, or the carrying out by the
                                    Bank or its agents or subcontractors of any
                                    instructions or requests of the Fund on
                                    behalf of the applicable Portfolio.

                           (e)      The offer or sale of Shares in violation of
                                    any requirement under the federal securities
                                    laws or regulations or the securities laws
                                    or regulations of any state that such Shares
                                    be registered in such state or in violation
                                    of any stop order or other determination or
                                    ruling by any federal agency or any state
                                    with respect to the offer or sale of such
                                    Shares in such state.

                           (f)      The negotiations and processing of checks
                                    made payable to prospective or existing
                                    Shareholders tendered to the Bank for the
                                    purchase of Shares, such checks are commonly
                                    known as "third party checks."

                  6.2      At any time the Bank may apply to any officer of the
                           Fund for instructions, and may consult with legal
                           counsel with respect to any matter arising in
                           connection

                           with the services to be performed by the Bank tinder
                           this Agreement, and the Bank and its agents or
                           subcontractors shall not be liable and shall be
                           indemnified by the Fund oil behalf of the applicable
                           Portfolio for any action taken or omitted by it in
                           reliance upon such instructions or upon the opinion
                           of such counsel (provided such counsel is reasonably
                           satisfactory to the Fund). The Bank, its agents and
                           subcontractors shall be protected and indemnified in
                           acting upon any paper or document, reasonably
                           believed to be genuine and to have been signed by the
                           proper person or persons, or upon any instruction,
                           information, data, records or documents provided the
                           Bank or its agents or subcontractors by machine
                           readable input, telex, CRT data entry or other
                           similar means authorized by the Fund, and shall not
                           be held to have notice of any change of authority of
                           any person, until receipt of written notice thereof
                           from the Fund. The Bank, its agents and
                           subcontractors shall also be protected and
                           indemnified in recognizing stock certificates which
                           are reasonably believed to bear the proper manual or
                           facsimile signatures of the officers of the Fund, and
                           the proper countersignature of any former transfer
                           agent or former registrar, or of a co-transfer agent
                           or co-registrar.

                  6.3      In the event either party is unable to perform its
                           obligations under the terms of this Agreement because
                           of acts of God, strikes, equipment or transmission
                           failure or damage reasonably beyond its control, or
                           other causes reasonably beyond its control, such
                           party shall not be liable for damages to the other
                           for any damages resulting from such failure to
                           perform or otherwise from such causes.

                  6.4      In order that the indemnification provisions
                           contained in this Section 6 shall apply, upon the
                           assertion of a claim for which the Fund may be
                           required to indemnify the Bank, the Bank shall
                           promptly notify the Fund of such assertion, and shall
                           keep the Fund advised with respect to all
                           developments concerning such claim. The Fund shall
                           have the option to participate with the Bank in the
                           defense of such claim or to defend against said claim
                           in its own name or in the name of the Bank. The Bank
                           shall in no case confess any claim or make any
                           compromise in any case in which the Fund may be
                           required to indemnify the Bank except with the Fund's
                           prior written consent.

                  Registrant has obtained from a major insurance carrier a
directors' and officers' liability policy covering certain types of errors and
omissions. In no event will Registrant indemnify any of its trustees, officers,
employees or agents against any liability to which such person would otherwise
be subject by reason of his willful misfeasance, bad faith or gross negligence
in the performance of his duties, or by reason of his reckless disregard of the
duties involved in the conduct of his office or under his agreement with
Registrant. Registrant will comply with Rule 484 under the Securities Act of
1933 and Release No. 11330 under the Investment Company Act of 1940 in
connection with any indemnification.

                  Insofar as indemnification for liability arising under the
Securities Act of 1933 may be permitted to directors, officers, and controlling
persons of Registrant pursuant to the foregoing provisions, or otherwise,
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, 


                                      C-14
<PAGE>   154



unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by Registrant of expenses incurred or paid
by a trustee, officer, or controlling person of Registrant in the successful
defense of any action, suit, or proceeding) is asserted by such trustee,
officer, or controlling person in connection with the securities being
registered, Registrant will, unless in the opinion of its counsel the matter has
been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
