  management services provided in connection with investment in the Fund. (See
  "HOW TO PURCHASE AND REDEEM INVESTOR SHARES--Purchases of Shares.")
2 The Group has adopted a Distribution and Shareholder Service Plan (the "Plan")
  pursuant to which a Fund is authorized to pay or reimburse the Distributor a
  periodic amount calculated at an annual rate not to exceed 0.25% of the
  average daily net assets of such Fund. Currently, however, it is intended that
  no such amounts will be paid under the Plan by any of the Funds. Shareholders
  will be given at least 30 days' notice prior to the payment of any fees under
  the Plan. As a result of expenses payable in connection with the Plan, it is
  possible that long-term shareholders may pay more than the economic equivalent
  of the maximum front-end sales charges permitted by the National Association
  of Securities Dealers.
3 Absent the reduction of distribution fees, "Total Fund Operating Expenses" as
  a percentage of average daily net assets would have been 1.26% for the U.S.
  Government Fund, 1.48% for the Fixed Income Fund, 1.58% for the Tax-Free Fund
  and 1.61% for the Equity Fund.

  The purpose of the above table is to assist a potential purchaser of a Fund's
Shares in understanding the various costs and expenses that an investor in a
Fund will bear directly or indirectly. Such expenses do not include any fees
charged by AMCORE Bank N.A., Rockford ("AMCORE Bank"), AMCORE Trust Company or
any of their affiliates to customer accounts which may have invested in Shares
of the Fund. During the current fiscal year, AMCORE and the Administrator
anticipate voluntarily reducing a portion of the fees payable to them which may
result in lower total operating expenses. See "MANAGEMENT OF THE GROUP" and
"GENERAL INFORMATION" for a more complete discussion of the Shareholder
transaction expenses and annual operating expenses for the Fund. THE FOREGOING
EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES.
ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

1 A Participating Organization (as defined in this Prospectus) or a Bank (as
  defined in this Prospectus) may charge a Customer's (as defined in the
  Prospectus) account fees for automatic investment and other investment
  management services provided in connection with investment in the Fund. (See
  "HOW TO PURCHASE AND REDEEM INVESTOR SHARES--Purchases of Shares.")
2 The Group has adopted a Distribution and Shareholder Service Plan (the "Plan")
  pursuant to which a Fund is authorized to pay or reimburse the Distributor a
  periodic amount calculated at an annual rate not to exceed 0.25% of the
  average daily net assets of such Fund. Currently, however, it is intended that
  no such amounts will be paid under the Plan by any of the Funds. Shareholders
  will be given at least 30 days' notice prior to the payment of any fees under
  the Plan. As a result of expenses payable in connection with the Plan, it is
  possible that long-term shareholders may pay more than the economic equivalent
  of the maximum front-end sales charges permitted by the National Association
  of Securities Dealers.
3 "Other Expenses" for the Balanced Fund, the Aggressive Growth Fund and the
  Fixed Total Return Fund are based on estimated amounts for the current fiscal
  year.
4 Absent the waiver of the full amount of distribution fees during the current
  fiscal year, it is estimated that "Total Fund Operating Expenses," as a
  percentage of average daily net assets, would have been 1.84% for the Balanced
  Fund, 2.00% for the Aggressive Growth Fund and 1.71% for the Fixed Total
  Return Fund.

         INVESTMENT OBJECTIVES, POLICIES AND RISK FACTORS OF THE FUNDS
 
  Each Fund has its own investment objective and policies, which are described
below. There is no assurance that a Fund will be successful in achieving its
investment objectives. The investment objective of each Fund is a fundamental
policy and, as such, may not be changed without a vote of the holders of a
majority of the outstanding Shares of a Fund (as described in the Statement of
Additional Information). The other policies of a Fund may be changed without a
vote of the holders of a majority of Shares unless (1) the policy is expressly
deemed to be a fundamental policy of the Fund or (2) the policy is expressly
deemed to be changeable only by such majority vote.
 
AMCORE VINTAGE U.S. GOVERNMENT OBLIGATIONS FUND.
 
  The investment objective of the U.S. Government Fund is to seek current income
consistent with maintaining liquidity and stability of principal. The Fund seeks
to maintain a stable net asset value of $1.00 per Share.
 
  The U.S. Government Fund invests exclusively in U.S. Treasury bills, notes and
other obligations issued or guaranteed by the U.S. Government or its agencies or
instrumentalities ("U.S. Government Obligations") which have remaining
maturities of 397 calendar days (thirteen months) or less, and in repurchase
agreements with respect to U.S. Government Obligations. The short-term U.S.
Government Obligations in the Fund's portfolio will differ only in their
interest rates, maturities and times of issuance. The dollar-weighted average
maturity of the obligations held by the U.S. Government Fund will not exceed 90
days.
 
AMCORE VINTAGE FIXED INCOME FUND.
 
  The investment objective of the Fixed Income Fund is to seek total return
consistent with the production of current income and the preservation of
capital. Total return will consist of interest from underlying securities and
capital appreciation reflected in unrealized increases in the value of portfolio
securities (realized by the Shareholder only if the Shareholder has sold its
Shares) or realized from the purchase and sale of securities. Because the market
value of fixed income securities can be expected to vary inversely to changes in
prevailing interest rates, investing in such fixed income securities can provide
an opportunity for capital appreciation when interest rates are expected to
decline.
 
  Under normal conditions, the Fixed Income Fund will invest substantially all,
but in no event less than 75%, of the value of its total assets in fixed income
securities with stated or in remaining maturities of 15 years or less or
securities with a stated or remaining maturity in excess of 15 years if such
securities have an unconditional put to sell or redeem the security within 15
years from the date of purchase. Such securities will include but not be limited
to, corporate debt securities (including notes, bonds and debentures) and U.S.
Government Obligations. The Fixed Income Fund expects to maintain a
dollar-weighted average portfolio maturity of four to six years.
 
  The remainder of the Fixed Income Fund's assets may be comprised of U.S.
Government Obligations and mortgage-related securities with stated or remaining
maturities that exceed 15 years, high quality money market instruments
(commercial paper, certificates of deposit and bankers' acceptances), variable
amount master demand notes, variable and floating rate notes, taxable municipal
bonds, leasing instruments and trust certificates and asset backed securities.
In addition, the Fixed Income Fund may engage in certain loans of portfolio
securities, repurchase agreements and reverse repurchase agreements. The Fixed
Income Fund may also invest in securities of other investment companies and in
other investment portfolios advised by AMCORE.
 
  The Fixed Income Fund expects 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, in the case of notes and
bonds, may be secured by mortgages on real property or security interests in
 
                                       11
<PAGE>   18
 
personal property and will in most cases differ in their interest rates,
maturities and times of issuance. The Fixed Income Fund will invest in such
corporate debt securities only if they are rated within the three highest rating
categories at the time of purchase by a nationally recognized statistical rating
organization (an "NRSRO") or, if unrated, found by AMCORE to be of comparable
quality. The respective rating services apply classifications in each rating
category to indicate the security's ranking within the category. The Fixed
Income Fund may invest in securities within any of the classifications in a
category. For a description of the rating symbols of certain NRSROs, see the
Appendix to the Statement of Additional Information.
 
  Subject to the foregoing limitations, the Fixed Income Fund may invest in U.S.
dollar-denominated international certificates of deposit, banker's acceptances
and foreign fixed income issues for which the primary trading market is in the
United States ("Yankee Obligations").
 
  The Fixed Income Fund will purchase commercial paper rated at the time of
purchase within the two highest rating categories by an NRSRO or, if not rated,
found by AMCORE to be of comparable quality. See the Appendix to the Statement
of Additional Information for a description of these ratings.
 
  For temporary defensive purposes, the Fixed Income Fund may invest all or any
portion of its assets in the money market instruments and repurchase agreements
described above when, in the opinion of AMCORE, it is in the best interests of
the Fund to do so.
 
AMCORE VINTAGE INTERMEDIATE TAX-FREE FUND.
 
  The Tax-Free Fund seeks to produce current income, consistent with the
preservation of capital, that is exempt from federal income taxes to the extent
described below. The Tax- Free Fund invests primarily in a diversified portfolio
of intermediate-term tax-free fixed income securities.
  Under normal market conditions at least 80% of the net assets of the Tax-Free
Fund will be invested in a diversified portfolio of obligations (such as bonds,
notes, and debentures) issued by or on behalf of states, territories and
possessions of the United States, the District of Columbia and other political
subdivisions, agencies, instrumentalities and authorities, the interest on which
is both exempt from regular federal income taxes and not treated as a preference
item for individuals for purposes of the federal alternative minimum tax
("Municipal Securities"). It should be noted that interest on such bonds will
nonetheless be part of an adjustment to the alternative minimum taxable income
for purposes of the alternative minimum tax imposed on corporations as well as
the environmental tax imposed on corporations under Section 59A of the Internal
Revenue Code of 1986, as amended. Under normal market conditions, the Tax-Free
Fund will invest in Municipal Securities that have a stated or remaining
maturity of 25 years or less or in Municipal Securities with a stated or
remaining maturity in excess of 25 years if such securities have an
unconditional put to sell or redeem the securities within 25 years from the date
of purchase. The Tax-Free Fund expects to maintain a dollar-weighted average
portfolio maturity of five to nine years.
 
  Under normal market conditions, the Tax-Free Fund may invest up to 20% of its
net assets in obligations the interest on which is either subject to regular
federal income taxation or treated as a preference item for purposes of the
federal alternative minimum tax ("Taxable Obligations"). At times, AMCORE may
determine that, because of unstable conditions in the markets for Municipal
Securities, pursuing the Tax-Free Fund's basic investment strategies is
inconsistent with the best interests of the Shareholders of the Tax-Free Fund.
At such times, AMCORE may use temporary defensive strategies differing from
those designed to achieve the Tax-Free Fund's investment objective, by
increasing the Tax-Free Fund's holdings in Taxable Obligations to over 20% of
the Tax-Free Fund's total assets and by holding uninvested cash reserves pending
investment. Taxable Obligations may include U.S. Government Obligations (some of
which may be subject to repurchase agreements), certificates of deposit, demand
and time deposits, and bankers' acceptances of selected banks, and com-
 
                                       12
<PAGE>   19
 
mercial paper meeting the Tax-Free Fund's quality standards (as described below)
for tax-exempt commercial paper. These obligations are described further in the
Statement of Additional Information.
 
  The Tax-Free Fund may also invest in private activity bonds. Interest on
private activity bonds is exempt from the regular federal income tax only if the
bonds fall within certain defined categories of qualified private activity bonds
and meet the requirements specified in those respective categories. Even if
private activity bonds so qualify, interest on private activity bonds may be
subject to the alternative minimum tax, and, in the case of corporate investors,
to the environmental tax under Code Section 59A. However, private activity bonds
will only be considered Municipal Securities for the purposes of this Prospectus
if the interest thereon is not an item of tax preference for individuals. For
additional information on the federal alternative minimum tax, see "DIVIDENDS
AND TAXES."
 
  The Tax-Free Fund invests in Municipal Securities that are rated within the
three highest rating categories at the time of purchase by an NRSRO in the case
of bonds and rated within the two highest rating categories in the case of
notes, tax-exempt commercial paper, and variable rate demand obligations. The
respective rating services apply classifications in each rating category to
indicate the security's ranking within the category. The Tax-Free Fund may
invest in securities within any of the classifications in a category. The Fund
may also invest up to 10% of the Tax-Free Fund's total assets in Municipal
Securities that are unrated at the time of purchase but are determined to be of
comparable quality by AMCORE pursuant to guidelines approved by the Group's
Board of Trustees. Municipal Securities may be purchased in reliance upon a
rating only when the rating organization is not affiliated with the issuer or
guarantor of the Municipal Securities. The applicable Municipal Securities
ratings are described in the Appendix to the Statement of Additional
Information.
 
  The two principal classifications of Municipal Securities that may be held by
the Tax-Free Fund are "general obligation" securities and "revenue" securities.
General obligation securities are secured by the issuer's pledge of its full
faith, credit and taxing power for the payment of principal and interest.
Revenue securities are payable only from the revenues derived from a particular
facility or class of facilities, or, in some cases, from the proceeds of a
special excise tax or other specific revenue source such as the user of the
facility being financed. Private activity bonds held by the Tax-Free 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.
 
  Municipal Securities in which the Tax-Free Fund may invest may also include
"moral obligation" bonds, which are normally issued by special purpose public
authorities. If the issuer of moral obligation bonds 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 that created the issuer.
 
  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 Tax-Free Fund, AMCORE,
nor legal counsel to either will review the proceedings relating to the issuance
of Municipal Securities or the basis for such opinions.
 
  The Tax-Free Fund does not intend to invest more than 25% of its total assets
in Municipal Securities which are related in such a way that an economic,
business, or political development or change affecting one such security would
likewise affect the other Municipal Securities. Examples of such securities are
obligations the repayment of which is dependent upon similar types of projects
or projects located in the same state. Such investments would be made only if
deemed necessary or appropriate by AMCORE. To the extent that the Tax-Free
Fund's assets are concentrated in Municipal Securities that are so related, the
Tax-Free Fund will be subject to the peculiar risks presented by
 
                                       13
<PAGE>   20
 
such Municipal Securities, such as negative developments in a particular
industry or state, to a greater extent than it would be if the Tax-Free Fund's
assets were not so concentrated.
 
  Municipal Securities purchased by the Tax-Free Fund may include rated and
unrated variable and floating rate tax-exempt notes. 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 Tax-Free Fund will approximate their par value. Variable
and floating rate notes for which no readily available market exists will be
purchased in an amount which, together with other securities which are not
readily marketable, exceeds 15% of the Tax-Free Fund's net assets only if such
notes are subject to a demand feature that will permit the Fund to receive
payment of the principal within seven days after demand by the Tax-Free Fund.
 
  The Tax-Free Fund may also invest in master demand notes in order to satisfy
short-term needs or, if warranted, as part of its temporary defensive investment
strategy. Such notes are demand obligations that permit the investment of
fluctuating amounts at varying market rates of interest pursuant to arrangements
between the issuer and a United States commercial bank acting as agent for the
payees of such notes. Master demand notes are direct lending arrangements
between the Tax-Free Fund and the issuer of such notes. Master demand notes are
callable on demand by the Tax-Free Fund, but are not marketable to third
parties. The quality of master demand notes will be reviewed by AMCORE at least
quarterly, which review will consider the earning power, cash flow and debt-to-
equity ratios indicating the borrower's ability to pay principal together with
accrued interest on demand. While master demand notes are not typically rated by
credit rating agencies, issuers of such notes must satisfy the same criteria for
the Tax-Free Fund set forth above for commercial paper.
 
AMCORE VINTAGE EQUITY FUND.
 
  The investment objective of the Equity Fund is long term capital appreciation.
The Equity Fund will invest primarily in equity securities of large
capitalization companies with strong earnings potential and will strive for high
over-all return while minimizing risk through the selection of quality dividend
paying equity securities.
 
  Under normal market conditions, the Equity Fund will invest substantially all,
but in no event less than 75%, of its total assets in equity securities, which
are defined as common stocks, preferred stocks, securities convertible into
common stocks, warrants and any rights to purchase common stocks. The remainder
of the Equity Fund's assets may be invested in U.S. Government Obligations and
repurchase agreements with respect thereto. The Equity Fund may also use call
options on equity securities, as described below. Because the market value of
fixed income securities, such as U.S. Government Obligations, can be expected to
vary inversely to changes in prevailing interest rates, investing in such fixed
income securities can provide an opportunity for capital appreciation when
interest rates are expected to decline.
 
  The Equity Fund may, for daily cash management purposes, also invest in high
quality money market securities (commercial paper, certificates of deposit and
bankers' acceptances), as well as the repurchase agreements referred to above.
In addition, the Equity Fund may invest, without limit, in any combination of
the U.S. Government Obligations, money market instruments and repurchase
agreements referred to above when, in the opinion of AMCORE, it is determined
that a temporary defensive position is warranted based upon current market
conditions. The Equity Fund may also invest in securities of other investment
companies including the other investment portfolios advised by AMCORE, as
described more fully under "Other Investment Policies."
 
  Subject to the foregoing limitations, the Equity Fund may invest in foreign
securities through the purchase of American Depository Receipts ("ADRs").
Ownership of unsponsored ADRs may
 
                                       14
<PAGE>   21
 
not entitle the Equity Fund to financial or other reports from the issuer, to
which it would be entitled as the owner of sponsored ADRs. Investment in foreign
securities is subject to special risks that differ in some respects from those
related to investments in securities of U.S. domestic issuers. Such risks
include trade balances and imbalances, and related economic policies, future
adverse political, economic and social developments, the possible imposition of
withholding taxes on interest and dividend income and other taxes, possible
seizure, nationalization, or expropriation of foreign investments or deposits,
currency blockage, less stringent disclosure requirements, the possible
establishment of exchange controls or taxation at the source, or the adoption of
other foreign governmental restrictions. For additional information regarding
the special risks associated with investments in foreign securities, see
"Foreign Investments" in the Statement of Additional Information.
 
AMCORE VINTAGE BALANCED FUND.
 
  The investment objective of the Balanced Fund is to seek long-term growth of
capital and income. The Balanced Fund will invest in a diversified portfolio of
equity securities and high quality fixed income securities. The investment
manager will allocate holdings within established ranges to best take advantage
of economic conditions, general market trends, interest rate levels, and changes
in fiscal and monetary policies.
 
  To the extent that the Balanced Fund invests in equity securities, it will
invest in the same types of equity securities identified above as permissible
investments for the Equity Fund, which consist of common stocks, preferred
stocks, securities convertible into common stocks, warrants and any rights to
purchase common stocks. Under normal market conditions, the Balanced Fund may
invest up to 75% of its total assets in equity securities. The Balanced Fund may
invest in foreign securities through the purchase of ADRs, as described above in
connection with the Equity Fund.
 
  To the extent that the Balanced Fund invests in fixed income securities, it
will invest in the same types of fixed income securities identified as
permissible investments for the Fixed Total Return Fund, which consist of
corporate debt securities (including notes, bonds and debentures), and U.S.
Government Obligations, as well as money market instruments. The fixed income
portion of the Balanced Fund will be subject to the same investment parameters
applicable to the Fixed Total Return Fund as regards security maturity
limitations (15 years or less maximum maturity) and dollar-weighted average
portfolio maturity (four to six years).
 
  Under normal market conditions the Balanced Fund will invest at least 25% of
its total assets in fixed income securities. In addition, the Balanced Fund may
invest, without limit, in any combination of U.S. Government Obligations, money
market instruments and repurchase agreements when, in the opinion of AMCORE, it
is determined that a temporary defensive position is warranted based upon
current market conditions.
 
AMCORE VINTAGE AGGRESSIVE GROWTH FUND.
 
  The investment objective of the Aggressive Growth Fund is long-term capital
growth. The Aggressive Growth Fund will invest primarily in equity securities of
companies that exhibit a strong potential for price appreciation relative to the
general equity markets. Dividend income is not a factor in selecting investment
securities. The Aggressive Growth Fund is managed without regard to tax
ramifications.
 
  The Aggressive Growth Fund may invest in the same types of equity securities
identified above as permissible investments for the Equity Fund, which consist
of common stocks, preferred stocks, securities convertible into common stocks,
warrants and any rights to purchase common stocks. The Aggressive Growth Fund
may invest in foreign securities through the purchase of ADRs, as described
above in connection with the Equity Fund.
 
  The manager will consider numerous factors in a company, among them; quality
of management over time, the company's leadership in its field, distinctive
marketing capabilities, return on equity over the past 3-5 years, cash flows,
debt levels, and earnings
 
                                       15
<PAGE>   22
 
growth. The Fund will seek positions in high growth industries, firms with
products in niche markets, and stocks which are perceived to be temporarily
undervalued. Positions may be accumulated in industry sectors or firms which are
felt to be particularly attractive; positions may be decreased or eliminated in
industry sectors or firms which are less attractive.
 
  The Aggressive Growth Fund may invest, without limit, in any combination of
U.S. Government Obligations, money market instruments and repurchase agreements
when, in the opinion of AMCORE, it is determined that a temporary defensive
position is warranted based upon current market conditions.
 
AMCORE VINTAGE FIXED TOTAL RETURN FUND.
 
  The investment objective of the Fixed Total Return Fund is to seek long-term
total return by investing in a diversified portfolio of fixed income securities.
Total return includes a combination of interest income from the Fund's
underlying fixed income securities, appreciation in the value of these fixed
income securities and gains realized upon the sale of such securities. Because
the market value of fixed income securities can be expected to vary inversely to
changes in prevailing interest rates, investing in such fixed income securities
provides an opportunity for appreciation when interest rates decline and risk
when interest rates rise. It is anticipated that the Fund will place primary
emphasis on capital appreciation as well as capital preservation through
periodic adjustment of the average maturity or duration of the Fund's portfolio
with the level of current income being a secondary consideration and that
investments will be made without regard to tax ramifications.
 
  Under normal market conditions, the Fixed Total Return Fund will invest in the
same types of fixed income securities having the same average maturities
identified above as permissible investments for the Fixed Income Fund (i.e.,
four to six years dollar-weighted average portfolio maturity and 15 years or
less maximum security limitation), which consist of corporate debt securities
(including notes, bonds and debentures) and U.S. Government Obligations, as well
as money market instruments.
 
  The Fixed Total Return Fund may invest in corporate debt securities rated
within the four highest rating categories at the time of purchase by an NRSRO,
or if unrated, found by AMCORE to be of comparable quality. Securities rated in
the fourth highest rating category have speculative characteristics, even though
they are of investment-grade quality, and in recognition of this fact, no more
than 15% of the Fund's total assets will be invested in securities rated in the
fourth rating category. The Fixed Total Return Fund, unlike the Fixed Income
Fund, may invest in Treasury Zero Coupon securities but it will not invest more
than 10% of its total assets in such securities.
 
U.S. GOVERNMENT OBLIGATIONS
 
  The types of U.S. Government Obligations invested in by a 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, bonds
and certificates of indebtedness, and obligations issued or guaranteed by the
agencies or instrumentalities of the U.S. Government, but not supported by such
full faith and credit. Obligations of certain agencies and instrumentalities of
the U.S. Government, such as the Government National Mortgage Association and
the Export-Import Bank of the United States, are supported by the full faith and
credit of the U.S. Treasury; others, such as those of the Federal National
Mortgage Association, are supported by the right of the issuer to borrow from
the Treasury; others are supported by the discretionary authority of the U.S.
Government to purchase the agency's obligations; still others, such as those of
the Federal Farm Credit Banks or the Federal Home Loan Mortgage Corporation, 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 agencies or instrumentalities if it is not obligated to do so by law.
A Fund will invest in the obligations of such agencies or instrumentalities only
when AMCORE believes that the credit risk with respect thereto is minimal. The
U.S. Government does not guarantee the market value of any security; there-
 
                                       16

fore, the market value of the U.S. Government Obligations in a Fund's portfolio
and of the Shares of a Fund can be expected to fluctuate as interest rates
change.
 
MORTGAGE-RELATED AND ASSET-BACKED SECURITIES
 
  Mortgage-related securities in which the Fixed Income Fund may invest
represent pools of mortgage loans assembled for sale to investors by various
governmental agencies (such as the Government National Mortgage Association) and
government-related organizations (such as the Federal National Mortgage
Association and the Federal Home Loan Mortgage Corporation), as well as by
private issuers (such as commercial banks, savings and loan institutions,
mortgage bankers and private mortgage insurance companies). Collateralized
mortgage obligations structured as pools of mortgage pass-through certificates
or mortgage loans ("CMOs") will be purchased only if they meet the rating
requirements set forth above with respect to the Fixed Income Fund's investments
in debt securities of U.S. corporations. For additional information on the Fixed
Income Fund's investments in mortgage-related securities, see the Statement of
Additional Information.
 
  Although certain mortgage-related securities may be guaranteed by a third
party or otherwise similarly secured, the market value of the security, which
may fluctuate, is not so secured. Thus, for example, if the Fund purchases a
mortgage-related security at a premium, that portion may be lost if there is a
decline in the market value of the security whether due to changes in interest
rates or prepayments of the underlying mortgage collateral. As with other
interest-bearing securities, the prices of mortgage-related securities are
inversely affected by changes in interest rates. However, although the value of
a mortgage-related security may decline when interest rates rise, the converse
is not necessarily true since, in periods of declining interest rates, the
mortgages underlying the securities are prone to prepayment. For this and other
reasons, the stated maturity of a mortgage-related security may be shortened by
unscheduled prepayments on the underlying mortgages and, accordingly, it is not
possible to predict accurately the security's return to the Fund. In addition,
regular payments received in respect to mortgage-related securities include both
interest and principal. No assurance can be given to the return the Fund will
receive when these amounts are reinvested.
 
  Asset-backed securities (unrelated to first mortgage loans) in which the Fixed
Income Fund may invest represent fractional interests in pools or leases, retail
installment loans or revolving credit receivables, both secured (such as
Certificates for Automobile Receivables or "CARSSM") and unsecured (such as
Credit Card Receivable Securities or "CARDSSM"). These assets are generally held
by a trust and payments of principal and interest or interest only are passed
through monthly or quarterly to certificate holders and may be guaranteed up to
certain amounts by letters of credit issued by a financial institution
affiliated or unaffiliated with the trustee or originator of the trust.
Asset-backed securities will be purchased only if they meet the rating
requirements set forth above with respect to the Fixed Income Fund's investments
in debt securities of U.S. corporations.
 
  Like mortgages underlying mortgage-backed securities, underlying automobile
sales contracts or credit card receivables are subject to prepayment, which may
reduce the overall return to certificate holders. Nevertheless, principal
repayment rates tend not to vary much with interest rates and the short-term
nature of the underlying car loans or other receivables tend to dampen the
impact of any change in the prepayment level. Certificate holders may also
experience delays in payment on the certificates if the full amounts due on
underlying sales contracts or receivables are not realized by the trust because
of unanticipated legal or administrative costs or enforcing the contracts or
because of depreciation or damage to the collateral (usually automobiles)
securing certain contracts, or other factors. If consistent with its investment
objective and policies, the Fixed Income Fund may invest in other asset-backed
securities that may be developed in the future.
 
                                       17
<PAGE>   24
 
  Issuers of mortgage-backed and asset-backed securities often issue one or more
classes of which one (the "Residual") is in the nature of equity. The Fixed
Income Fund will not invest in any Residual.
 
REPURCHASE AGREEMENTS
 
  Securities held by a Fund may be subject to repurchase agreements. Under the
terms of a repurchase agreement, a Fund would acquire securities from member
banks of the Federal Deposit Insurance Corporation and from registered
broker-dealers which AMCORE deems creditworthy under guidelines approved by the
Group's Board of Trustees. The seller agrees to repurchase such securities at a
mutually agreed-upon date and price. The repurchase price would generally equal
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. Securities subject to repurchase agreements must be of the
same type and quality although, for the U.S. Government Fund, not subject to the
same maturity requirements as those in which a Fund may invest directly. The
seller under a repurchase agreement will be required to maintain at all times
the value of collateral held pursuant to the agreement at not less than the
repurchase price (including accrued interest). This requirement will be
continually monitored by AMCORE. In addition, securities subject to a repurchase
agreement will be held in a segregated account. If the seller were to default on
its repurchase obligation or become insolvent, a Fund would suffer a loss if the
proceeds from a sale of the underlying portfolio securities were less than the
repurchase price under the agreement, or the disposition of such securities by a
Fund were delayed pending court action. Repurchase agreements are considered to
be loans collateralized by the underlying security under the Investment Company
Act of 1940 (the "1940 Act"). For further information about repurchase
agreements, see "INVESTMENT OBJECTIVE AND POLICIES-- Additional Information on
Portfolio Instruments-- Repurchase Agreements" in the Statement of Additional
Information.
 
REVERSE REPURCHASE AGREEMENTS
 
  Each Fund may borrow funds for temporary purposes by entering into reverse
repurchase agreements in accordance with the investment restrictions described
below. Pursuant to such agreements, a Fund would sell certain of its securities
to financial institutions such as banks and broker-dealers, and agree to
repurchase them at a mutually agreed upon date and price. At the time a Fund
enters into a reverse repurchase agreement, it will place in a segregated
custodial account liquid high grade debt securities, such as U.S. Government
Obligations, consistent with its investment restrictions having a value equal to
the repurchase price (including accrued interest), and will subsequently
continually monitor the account to ensure that such equivalent value is
maintained at all times. Reverse repurchase agreements involve the risk that the
market value of 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 an investment company under the 1940 Act. For
further information about reverse repurchase agreements, see "INVESTMENT
OBJECTIVES AND POLICIES--Additional Information on Portfolio
Instruments--Reverse Repurchase Agreements" in the Statement of Additional
Information.
 
CALL OPTIONS
 
  The Equity Fund, the Balanced Fund and the Aggressive Growth Fund may write
covered call options on securities owned by the Fund. Such instruments may also
be referred to as equity derivatives. Derivatives generally are instruments
whose value is derived from or related to the value of some other instrument,
asset or specified benchmark, such as a specific stock or stock index. A call
option gives the purchaser of the option the right to buy, and obligates the
seller of the option 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. When a Fund writes a covered call option and such
option is exercised, it will forgo the appreciation, if any, on the underlying
security in excess of the exercise
 
                                       18
<PAGE>   25
 
price. In order to close out a call option it has written, a Fund may enter into
a "closing purchase transaction"--the purchase of a call option on the same
security with the same exercise price and expiration date as the call option
which the Fund previously wrote on any particular securities. When a portfolio
security subject to a call option is sold, the Fund may effect a closing
purchase transaction to close out any existing call option on that security. If
a Fund is unable to effect a closing purchase transaction, it will not be able
to sell the underlying security until the option expires or the Fund delivers
the underlying security upon exercise. Under normal conditions, it is not
expected that these Funds would permit the underlying value of their portfolio
securities subject to such options to exceed 15% of net assets.
 
PUTABLE SECURITIES
 
  The Fixed Income Fund, the Fixed Total Return Fund, the Balanced Fund and the
Tax-Free Fund may acquire puts with respect to fixed income securities or
Municipal Securities as described above. Under a put, a Fund would have the
right to sell or redeem a specified security at a certain time or within a
certain period of time at a specified price. The security is sold to a third
party or redeemed by the issuer as provided contractually. The put may be an
independent feature or may be combined with a reset feature that is designed to
reduce downward price volatility as interest rates rise by enabling the holder
to liquidate the investment prior to maturity. The Funds may acquire putable
securities to facilitate portfolio liquidity, shorten the maturity of the
underlying security, or to permit the investment of funds at a more favorable
rate of return. The price of a putable security may be higher than the price
which otherwise would be paid for the security without such put feature, thereby
increasing the security's cost and reducing its yield. The time remaining to the
put date will apply for purposes of determining the maximum maturity of such
securities.
 
LENDING OF PORTFOLIO SECURITIES
 
  From time to time in order to generate additional income, a Fund may lend its
portfolio securities, provided such action is consistent with its investment
objective, policies, and restrictions. During the time portfolio securities are
on loan, the borrower will pay a Fund any dividends or interest paid on the
securities. In addition, loans will be subject to termination by a Fund or the
borrower at any time.
 
  A Fund will enter into loan arrangements only with broker-dealers, banks or
other institutions that are not affiliated directly or indirectly with the Group
and which AMCORE has determined are creditworthy under guidelines established by
the Group's Board of Trustees. While the lending of securities may subject a
Fund to certain risks, such as delays or an inability to regain the securities
in the event the borrower defaults on its lending agreement or enters into
bankruptcy, a Fund will receive 100% collateral on loaned securities in the form
of cash or U.S. Government Obligations. This collateral will be valued daily by
AMCORE and, should the market value of the loaned securities increase, the
borrower will be required to furnish additional collateral to the Fund. Although
each of the Funds does not expect to do so on a regular basis, it may lend
portfolio securities in amounts representing up to 15% of the value of the
Fund's total assets. Fees earned by the Tax-Free Fund from lending its
securities will constitute taxable income to the Fund which, when distributed to
shareholders, will likewise generally be treated as taxable income.
 
WHEN-ISSUED AND DELAYED-DELIVERY TRANSACTIONS
 
  A Fund may purchase securities on a when-issued or delayed-delivery basis. A
Fund will engage in when-issued and delayed-delivery transactions only for the
purpose of acquiring portfolio securities consistent with its investment
objectives and policies, not for investment leverage. When-issued securities are
securities purchased for delivery beyond the normal settlement date at a stated
price and yield and thereby involve a risk that the yield obtained in the
transaction will be less than those available in the market when delivery takes
place. A
 
                                       19
<PAGE>   26
 
Fund will generally not pay for such securities or start earning interest on
them until they are received. When a Fund agrees to purchase such securities,
however, the Fund's custodian will set aside cash or liquid securities equal to
the amount of the commitment in a separate account. Securities purchased on a
when-issued basis are recorded as an asset and are subject to changes in the
value based upon changes in the general level of interest rates. In when-issued
and delayed-delivery transactions, a Fund relies on the seller to complete the
transaction; the seller's failure to do so may cause a Fund to miss a price or
yield considered to be advantageous.
 
  The Fixed Income Fund's, the Fixed Total Return Fund's, the Tax-Free Fund's
and the U.S. Government Fund's commitments to purchase when-issued securities
will not exceed 25%, and the Equity Fund's, the Balanced Fund's and the
Aggressive Growth Fund's commitments will not exceed 5%, of the value of its
total assets absent unusual market conditions. Each of the Funds does not intend
to purchase when-issued securities for speculative purposes but only in
furtherance of its investment objectives.
 
OTHER INVESTMENT POLICIES
 
  Each of the Funds, except the U.S. Government Fund, may also invest up to 5%
of its total assets in another investment company, including the U.S. Government
Fund, not to exceed 10% of the value of its total assets in the securities of
other investment companies. In order to avoid the imposition of additional fees
as a result of investing in Shares of the U.S. Government Fund, AMCORE and the
Administrator (see "MANAGEMENT OF THE GROUP--Investment Adviser", "MANAGEMENT OF
THE GROUP--Administrator and Distributor") will waive any portion of their usual
service fees from that Fund that are attributable to investments therein by
another Fund. A Fund will incur additional expenses due to the duplication of
expenses as a result of investing in mutual funds other than the Funds.
Additional restrictions on a Fund's investments in the securities of other
mutual funds are contained in the Statement of Additional Information.
 
  The Funds will not execute portfolio transactions through, acquire portfolio
securities issued by, make savings deposits in, or enter into repurchase
agreements or reverse repurchase agreements with AMCORE, the Distributor or
their affiliates, and will not give preference to AMCORE Bank's correspondents
with respect to such transactions, securities, savings deposits, and agreements.
 
                            INVESTMENT RESTRICTIONS
 
  A Fund is subject to a number of investment restrictions that may be changed
only by a vote of a majority of the outstanding Shares of such a Fund (as
defined in the Statement of Additional Information).
 
  Each of the Fixed Income Fund, the Tax-Free Fund, the Equity Fund, the
Balanced Fund, the Aggressive Growth Fund and the Fixed Total Return Fund will
not:
 
    1. 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, with respect to 75% of its portfolio, more
  than 5% of the value of the total assets of the Fund 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.
 
  Each of the Fixed Income Fund, the Equity Fund, the Balanced Fund, the
Aggressive Growth Fund and the Fixed Total Return Fund will not:
 
    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 securities
  of one or more issuers conducting their
 
                                       20
<PAGE>   27
 
  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 the activities of their 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.
 
  The Tax-Free Fund will not:
 
    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 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) there is no limitation
  with respect to Municipal Securities, which, for purposes of this limitation
  only, do not include private activity bonds that are backed only by the assets
  and revenues of a non-governmental user; (c) wholly-owned finance companies
  will be considered to be in the industries of their parents if their
  activities are primarily related to financing the activities of their parents;
  and (d) 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. Write or sell puts, calls, straddles, spreads or combinations thereof
  except that the Fund may acquire puts with respect to Municipal Obligations in
  its portfolio and sell those puts in conjunction with a sale of those
  Municipal Obligations.
 
  Each of the Funds will not:
 
    1. Borrow money or issue senior securities, except that the Fund may borrow
  from banks or enter into reverse repurchase agreements for temporary purposes
  in amounts up to 10% of the value of its total assets at the time of such
  borrowing; or mortgage, pledge, or hypothecate any assets, except in
  connection with any such borrowing and in amounts not in excess of the lesser
  of the dollar amounts borrowed or 10% of the value of the Fund's total assets
  at the time of its borrowing. The Fund will not purchase securities while
  borrowings (including reverse repurchase agreements) in excess of 5% of its
  total assets are outstanding.
 
    2. Make loans, except that the Fund may purchase or hold debt securities and
  lend portfolio securities in accordance with its investment objective and
  policies, and may enter into repurchase agreements.
 
  In addition to the above investment restrictions, each Fund is subject to
certain other investment restrictions set forth under "INVESTMENT OBJECTIVES AND
POLICIES--Investment Restrictions" in the Funds' Statement of Additional
Information.
 
                              VALUATION OF SHARES
 
  The net asset value of each of the Funds, except the U.S. Government Fund, is
 determined and its Shares are priced as of the close of regular trading on the
  New York Stock Exchange ("NYSE") (generally 4:00 p.m. Eastern Time) on each
Business Day. The net asset value of the U.S. Government Fund is determined and
  its Shares are priced as of 12:00 noon Central Time and the close of regular
trading on the NYSE on each Business Day ("Valuation Times"). As used herein, a
 "Business Day" constitutes any day on which the NYSE is open for trading, the
Federal Reserve Bank of Chicago is open, and any other day except days on which
                 there are not sufficient changes in the value
 
                                       21
<PAGE>   28
 
of the Fund's portfolio securities that the Fund's net asset value might be
materially affected and days during which no Shares are tendered for redemption
and no orders to purchase Shares are received. Currently, either the NYSE or
Federal Reserve Bank of Chicago are closed on New Year's Day, Martin Luther
King, Jr. Day, President's Day, Good Friday, Memorial Day, Independence Day,
Labor Day, Columbus Day, Veteran's Day, Thanksgiving Day and Christmas Day. Net
asset value per Share for purposes of pricing sales and redemptions is
calculated by dividing the value of all securities and other assets of the Fund
less the liabilities charged to the Fund by the number of its outstanding
Shares.
 
  For the Fixed Income Fund, the Tax-Free Fund, the Equity Fund, The Balanced
Fund, the Aggressive Growth Fund and the Fixed Total Return Fund (the "Variable
NAV Funds"), the net asset value per share will fluctuate as the value of the
Variable NAV Fund's investment portfolio changes.
 
  The securities in the Variable NAV Funds will be valued at market value. If
market quotations are not available, the securities will be valued by a method
which the Board of Trustees believes accurately reflects fair value. For further
information about valuation of investments, see "NET ASSET VALUE" in the
Statement of Additional Information.
 
  The assets in the U.S. Government Fund are valued based upon the amortized
cost method, which the Trustees of the Group believe fairly reflect the
market-based net asset value per Share. Pursuant to rules and regulations of the
Commission regarding the use of the amortized cost method, the U.S. Government
Fund will maintain a dollar-weighted average portfolio maturity of 90 days or
less. Although the Group seeks to maintain the U.S. Government Fund's net asset
value per share at $1.00, there can be no assurance that the net asset value
will not vary.
 
                       HOW TO PURCHASE AND REDEEM SHARES
 
DISTRIBUTOR
 
  Shares of the Funds are sold on a continuous basis by the Group's Distributor,
The Winsbury Company. The principal office of the Distributor is 1900 East
Dublin-Granville Road, Columbus, Ohio 43229. If you wish to purchase Shares,
contact the Funds at (800) 438-6375.
 
PURCHASES OF SHARES
 
  Shares of the Funds are continuously offered and may be purchased directly
either by mail, by telephone or by electronic transfer. Shares may also be
purchased through a broker-dealer who has established a dealer agreement with
the Distributor. The minimum investment is generally $1,000 for the initial
purchase of Shares and $50 for subsequent purchases. For purchases that are made
in connection with 401(k) plans, 403(b) plans and other similar plans or payroll
deduction plans, the minimum investment amount for initial and subsequent
purchases is $25. In the case of such retirement plan investments, the minimum
purchase amounts are not restricted to the purchase of Shares of one Fund. Thus,
the $25 minimum amount may be spread among any of the Funds. (But, see "HOW TO
PURCHASE AND REDEEM SHARES-- Auto Invest Plan" below for minimum investment
requirements under the Auto Invest Plan).
 
  Purchasers of Shares of the Funds will pay the sum of the next calculated net
asset value per Share after the Distributor's receipt of an order to purchase
Shares in good form ("public offering price") (see "HOW TO PURCHASE AND REDEEM
SHARES" below).
 
  In the case of orders for the purchase of Shares placed through a
broker-dealer, the public offering price will be the net asset value as so
determined, but only if the broker-dealer receives the order prior to the
Valuation Time for that day and transmits it to the Funds by the Valuation Time.
The broker-dealer is responsible for transmitting such orders promptly. If the
broker-dealer fails to do so, the
 
                                       22
<PAGE>   29
 
investor's right to that day's closing price must be settled between the
investor and the broker-dealer. If the broker-dealer receives the order after
the Valuation Time for that day, the price will be based on the net asset value
determined as of the Valuation Time for the next Business Day.
 
Purchases By Mail
 
  To purchase Shares of a Fund, complete an Account Application and return it
along with a check (or other negotiable bank draft or money order) in at least
the minimum initial purchase amount, made payable to the appropriate Fund to:
 
                              AMCORE Vintage Funds
                                  Dept. L-1392
                           Columbus, Ohio 43260-1392
 
  An Account Application form can be obtained by calling the Funds at (800)
438-6375. Subsequent purchases of Shares of a Fund may be made at any time by
mailing a check payable to a Fund, to the above address.
 
Purchases by Telephone
 
  Shares of a Fund may be purchased by calling the Funds at (800) 438-6375, if
your Account Application has been previously received by the Distributor.
Payment for Shares ordered by telephone is made by electronic transfer to the
Funds' custodian. Prior to wiring funds and in order to ensure that wire orders
are invested promptly, investors must call the Funds at the number above to
obtain instructions regarding the bank account number to which the funds should
be wired and other pertinent information.
 
Other Information Regarding Purchases
  Shares may also be purchased through procedures established by the Distributor
in connection with the requirements of qualified accounts maintained by or on
behalf of certain persons ("Customers") by AMCORE Bank, its related companies or
their correspondents ("Banks"). Shares of a Fund sold to the Banks acting in a
fiduciary, advisory, custodial, or other similar capacity on behalf of Customers
will normally be held of record by the Banks. With respect to Shares sold, it is
the responsibility of the holder of record to transmit purchase or redemption
orders to the Distributor and to deliver funds for the purchase thereof by the
Fund's custodian within the settlement requirements defined in the Securities
Exchange Act of 1934. If payment is not received within the prescribed time
periods or a check timely received does not clear, the purchase will be canceled
and the investor could be liable for any losses or fees incurred. Any questions
regarding current settlement requirements or electronic payment instructions
should be directed to the Group at (800) 438-6375.
 
  Purchases of Shares in a Fund will be effected only on a Business Day (as
defined in "VALUATION OF SHARES"). The public offering price of the Variable NAV
Funds will be the net asset value per Share (see "VALUATION OF SHARES") as
determined on the Business Day the order is received by the Distributor, but
only if the Distributor receives the order by the Valuation Time. Otherwise, the
price will be determined as of the Valuation Time on the next Business Day. In
the case of an order for the purchase of Shares placed through a broker-dealer,
it is the responsibility of the broker-dealer to transmit the order to the
Distributor promptly.
 
  Shares of the U.S. Government Fund are purchased at the net asset value per
Share (see "VALUATION OF SHARES") next determined after receipt by the
Distributor of an order to purchase Shares. An order to purchase Shares of the
U.S. Government Fund will be deemed to have been received by the Distributor
only when federal funds with respect thereto are available to the Funds'
custodian for investment. Federal funds are monies credited to a bank's account
with a Federal Reserve Bank. Payment for an order to purchase Shares of the U.S.
Government Fund which is transmitted by federal funds wire will be available the
same day for investment by the Funds' custodian, if received prior to the last
Valuation Time (see "VALUATION OF SHARES"). Payments transmitted by other means
(such as by check drawn on a member of the Federal Reserve System) will normally
be converted into federal funds within two banking
 
                                       23
<PAGE>   30
 
days after receipt. The U.S. Government Fund strongly recommends that investors
of substantial amounts use federal funds to purchase Shares.
 
  An order received prior to a Valuation Time on any Business Day for the U.S.
Government Fund will be executed at the net asset value determined as of the
next Valuation Time on the date of receipt. An order received after the last
Valuation Time on any Business Day will be executed at the net asset value
determined as of the next Valuation Time on the next Business Day of the U.S.
Government Fund. Shares purchased before 11:00 a.m., Central Time, begin earning
dividends on the same Business Day. Shares purchased after 11:00 a.m., Central
Time, begin earning dividends on the next Business Day. All Shares of the U.S.
Government Fund continue to earn dividends through the day before their
redemption.
 
  Depending upon the terms of the particular Customer account, a Bank may charge
a Customer account fees for services provided in connection with investments in
a Fund. Information concerning these services and any charges will be provided
by the Bank. This Prospectus should be read in conjunction with any such
information so received from a Bank.
 
  The Group reserves the right to reject any order for the purchase of a Fund's
Shares in whole or in part including purchases made with foreign and third party
checks.
 
  Every Shareholder of record will receive a confirmation of each transaction in
his or her account, which will also show the total number of Shares of a Fund
owned by the Shareholder. Sending confirmations for purchases and redemptions of
Shares held by a Bank on behalf of its Customer will be the responsibility of
the Bank. Shareholders may rely on these statements in lieu of certificates.
Certificates representing Shares of the Funds will not be issued.
 
  The Distributor, at its expense, will also provide other compensation to
dealers in connection with sales of Shares of a Fund. 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 of the Funds, and 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 Shares. Compensation will also include payment for travel
expenses, including lodging, incurred in connection with trips taken by invited
registered representatives and members of their families to locations within or
outside of the United States for meetings or seminars of a business nature.
Compensation will also include the following types of non-cash compensation
offered through sales contests: (1) vacation trips, including the provision of
travel arrangements and lodging at luxury resorts at exotic locations; (2)
tickets for entertainment events (such as concerts, cruises and sporting events)
and (3) merchandise (such as clothing, trophies, clocks and pens). Dealers may
not use sales of 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. None of the aforementioned
compensation is paid for by the Funds or their Shareholders.
 
AMCORE INDIVIDUAL RETIREMENT ACCOUNT ("IRA")
 
  An AMCORE IRA enables individuals, even if they participate in an
employer-sponsored retirement plan, to establish their own retirement program.
AMCORE IRA contributions may be tax-deductible and earnings are tax-deferred.
Under the Tax Reform Act of 1986, the tax deductibility of IRA contributions is
restricted or eliminated for individuals who participate in certain employer
pension plans and whose annual income exceeds certain limits. Existing IRAs and
future contributions up to the IRA maximums, whether deductible or not, still
earn income on a tax-deferred basis.
 
  All AMCORE IRA distribution requests must be made in writing to the
Distributor. Any additional deposits to an AMCORE IRA must distinguish the type
and year of the contribution.

  For more information on an AMCORE IRA call the Funds at (800) 438-6375.
Investment in Shares of the Tax-Free Fund would not be appropriate for any IRA.
Shareholders are advised to consult a tax adviser on AMCORE IRA contribution and
withdrawal requirements and restrictions.
 
AUTO INVEST PLAN
 
  The Auto Invest Plan enables Shareholders of the Funds to make regular monthly
or quarterly purchases of Shares through automatic deductions from their bank
accounts (which must be with a domestic member of the Automatic Clearing House).
With Shareholder authorization, the Transfer Agent will deduct the amount
specified from the Shareholder's bank account which will automatically be
invested in Shares at the public offering price on the dates of the deduction.
The required minimum initial investment when opening an account using the Auto
Invest Plan is $250; the minimum amount for subsequent investments in a Fund is
$25. To participate in the Auto Invest Plan, Shareholders should complete the
appropriate section of the account application which can be acquired by calling
(800) 438-6375. For a Shareholder to change the Auto Invest instructions, the
request must be made in writing to the Distributor.
 
EXCHANGE PRIVILEGE
 
  The Funds offer an exchange program whereby Shareholders are entitled to
exchange their Shares for Shares of the other Funds. Such exchanges will be
executed on the basis of the relative net asset values of the Shares exchanged.
The Shares exchanged must have a current value that equals or exceeds the
minimum investment that is required (either the minimum amount required for
initial or subsequent investments as the case may be) for the Fund whose Shares
are being acquired. Share exchanges will only be permitted where the Shares to
be acquired may legally be sold in the investor's state of residence. An
exchange is considered to be a sale of Shares for federal income tax purposes on
which a Shareholder may realize a taxable gain or loss. A Shareholder may make
an exchange request by calling the Funds at (800) 438-6375 or by providing
written instructions to the Funds. An investor should consult the Funds for
further information regarding exchanges. During periods of significant economic
or market change, telephone exchanges may be difficult to complete. If a
Shareholder is unable to contact the Funds by telephone, a Shareholder may also
mail the exchange request to the Funds at the address listed under "HOW TO
PURCHASE AND REDEEM SHARES--Redemption By Mail." The Funds reserve the right to
modify or terminate the exchange privilege described above at any time and to
reject any exchange request. If an exchange request in good order is received by
the Distributor by the last Valuation Time, on any Business Day, the exchange
usually will occur on that day. Any Shareholder who wishes to make an exchange
should obtain and review the current prospectus of the Fund in which he or she
wishes to invest before making the exchange. Shareholders wishing to make use of
the Funds' exchange program must so indicate on the Account Application.
 
AUTO EXCHANGE
 
  Auto Exchange enables Shareholders to make regular, automatic withdrawals from
the U.S. Government Fund and use those proceeds to benefit from dollar-cost
averaging by automatically making purchases of shares of another AMCORE Fund.
With shareholder authorization, the Group's transfer agent will withdraw the
amount specified (subject to the applicable minimums) from the shareholder's
U.S. Government Fund account and will automatically invest that amount in the
AMCORE Fund designated by the Shareholder at the public offering price on the
date of such deduction. In order to participate in the Auto Exchange,
Shareholders must have a minimum initial purchase of $10,000 in their U.S.
Government Fund account and maintain a minimum account balance of $1,000. To
participate in the Auto Exchange, Shareholders should complete the appropriate
section of the Account Registration Form, which can be acquired by calling the
Distributor. To change the Auto Exchange instructions or to discontinue
 
                                       25
<PAGE>   32
 
the feature, a Shareholder must send a written request to the AMCORE Vintage
Funds, Department L-1392, Columbus, OH 43260-1392. The Auto Exchange may be
amended or terminated without notice at any time by the Distributor.
 
REDEMPTION OF SHARES
 
  Shareholders may redeem their Shares on any day that net asset value is
calculated (see "VALUATION OF SHARES"). Redemptions will be effected at the net
asset value per share next determined after receipt of a redemption request in
good order. Redemptions may ordinarily be requested by mail or by telephone.
 
  All or part of a Customer's Shares may be required to be redeemed in
accordance with instructions and limitations pertaining to his or her account
held by a Bank. For example, if a Customer has agreed to maintain a minimum
balance in his or her account, and the balance in that account falls below that
minimum, the Customer may be obliged to redeem, or the Bank may redeem for and
on behalf of the Customer, all or part of the Customer's Shares to the extent
necessary to maintain the required minimum balance. There may be no notice
period affording Shareholders an opportunity to increase the account balance in
order to avoid an involuntary redemption under these circumstances.
 
REDEMPTION BY MAIL
 
  A written request for redemption must be received by the Funds in order to
honor the request. The Funds' address is: 1900 East Dublin-Granville Road,
Columbus, Ohio 43229. The Transfer Agent may require a signature guarantee by an
eligible guarantor institution. For purposes of this policy, the term "eligible
guarantor institution" shall include banks, brokers, dealers, credit unions,
securities exchanges and associations, clearing agencies and savings
associations as those terms are defined in Rule 17Ad-15 under the Securities
Exchange Act of 1934. The Transfer Agent reserves the right to reject any
signature guarantee if (1) it has reason to believe that the signature is not
genuine, (2) it has reason to believe that the transaction would otherwise be
improper, or (3) the guarantor institution is a broker or dealer that is neither
a member of a clearing corporation nor maintains net capital of at least
$100,000. The signature guarantee requirement will be waived if all of the
following conditions apply: (1) the redemption check is payable to the
Shareholder(s) of record and (2) the redemption check is mailed to the
Shareholder(s) at the address of record or the proceeds are either mailed or
wired to a commercial bank account previously designated on the Account
Application. There is no charge for having redemption requests mailed to a
designated bank account.
 
  If the Group receives a redemption order but a shareholder has not clearly
indicated the amount of money or number of shares involved, the Group cannot
execute the order. In such cases, the Group will request the missing information
and process the order on the day such information is received.
 
REDEMPTION BY TELEPHONE
 
  Shares may be redeemed by telephone if the Shareholder selected that option on
the Account Application. The Shareholder may have the proceeds mailed to his or
her address or mailed or sent electronically to a commercial bank account
previously designated on the Account Application. Electronic payment requests
may be made by the Shareholder by telephone to the Funds at (800) 438-6375. For
a wire redemption, the then-current wire redemption charge may be deducted from
the proceeds of a wire redemption. This charge, if applied, is presently $7.50
for each wire redemption. It is not necessary for Shareholders to confirm
telephone redemption requests in writing. During periods of significant economic
or market change, telephone redemptions may be difficult to complete. If a
Shareholder is unable to contact the Funds by telephone, a Shareholder may also
mail the redemption request to the Distributor at the address listed above under
"HOW TO PURCHASE AND REDEEM SHARES--Redemption by Mail". Neither the
Distributor, the Transfer Agent, AMCORE nor the Group will be liable for any
losses, damages, expense or cost arising out of any telephone transaction
(including
 
                                       26
<PAGE>   33
 
exchanges and redemptions) effected in accordance with the Funds' telephone
transaction procedures, upon instructions reasonably believed to be genuine. The
Fund will employ procedures designed to provide reasonable assurance that
instructions by telephone are genuine; if these procedures are not followed, the
Fund or its service contractors may be liable for any losses due to unauthorized
or fraudulent instructions. These procedures include recording all phone
conversations, sending confirmations to shareholders within 72 hours of the
telephone transaction, verification of account name and account number or tax
identification number, and sending redemption proceeds only to the address of
record or to a previously authorized bank account.
 
REDEMPTION BY CHECK
 
  Free check writing is available for the U.S. Government Fund. With this
service, a Shareholder may write up to five checks a month in amounts of $250 or
more. To establish this service and to obtain checks at the time the account is
opened, a Shareholder must complete the Signature Card that accompanies the
Account Application Form. To establish this service and obtain checks after
opening an account in the U.S. Government Fund, the Shareholder must contact the
Funds by telephone or mail to obtain an Account Application Form and complete
and return the signature card. A Shareholder will receive the dividends and
distributions declared on the Shares to be redeemed up to the day that a check
is presented for payment. Upon 30 days' prior written notice to Shareholders,
the check writing privilege may be modified or terminated. An investor may not
close a Fund account by writing a check.
 
AUTO WITHDRAWAL PLAN
 
  The Auto Withdrawal Plan enables Shareholders of a Fund to make regular
monthly or quarterly redemptions of Shares. With Shareholder authorization, the
Transfer Agent will automatically redeem Shares at the net asset value on the
dates of the withdrawal and have a check in the amount specified mailed to the
Shareholder. The required minimum withdrawal is $100. To participate in the Auto
Withdrawal Plan, Shareholders should call (800) 438-6375 for more information.
Purchases of additional Shares concurrent with withdrawals may be
disadvantageous to certain Shareholders because of tax liabilities. For a
Shareholder to change the Auto Withdrawal instructions the request must be made
in writing to the Distributor.
 
DIRECTED DIVIDEND OPTION
 
  A Shareholder may elect to have all income dividends and capital gains
distributions paid by check or reinvested in any of the Group's other funds,
(provided the other Fund is maintained at the minimum required balance).
 
  The Directed Dividend Option may be modified or terminated by the Group at any
time after notice to participating Shareholders. Participation in the Directed
Dividend Option may be terminated or changed by the Shareholder at any time by
writing the Distributor. The Directed Dividend Option is not available to
participants in an AMCORE IRA.
 
PAYMENTS TO SHAREHOLDERS
 
  Redemption orders are effected at the net asset value per Share next
determined after the Shares are properly tendered for redemption, as described
above. Payment to Shareholders for Shares redeemed will be made within the
settlement requirements defined in the Securities Exchange Act of 1934 after
receipt by the Distributor of the request for redemption. However, to the
greatest extent possible, the Group will attempt to honor requests from
Shareholders for (a) same day payments upon redemption of U.S. Government Fund
Shares if the request for redemption is received by the Distributor before 12:00
noon Central Time on a Business Day or, if the request for redemption is
received after 12:00 noon Central Time, to honor requests for payment on the
next Business Day, or (b) next day payments upon redemption of the Variable NAV
Funds if received by the Distributor before the last Valuation Time on a
Business Day or if the request for redemption is received after the last
Valuation Time, to honor requests for payment within two Business Days, unless
it would be disadvantageous
 
                                       27
<PAGE>   34
 
to the Fund or the Shareholders of the Fund to sell or liquidate portfolio
securities in an amount sufficient to satisfy requests for payments in that
manner.
 
  At various times, a Fund may be requested to redeem Shares for which it has
not yet received good payment. In such circumstances, a Fund may delay the
forwarding of proceeds until payment has been collected for the purchase of such
Shares, which delay may be for up to 10 days or more. A Fund intends to pay cash
for all Shares redeemed, but under abnormal conditions which make payment in
cash unwise, a Fund may make payment wholly or partly in portfolio securities at
their then-current market value equal to the redemption price. In such cases, an
investor may incur brokerage costs in converting such securities to cash.
 
  Due to the relatively high cost of handling small investments, the Funds
reserve the right to redeem, at net asset value, the Shares of any Shareholder
if, because of redemptions of Shares by or on behalf of the Shareholder (but not
as a result of a decrease in the market price of such Shares), the account of
such Shareholder has a value of less than $500. Before the Funds exercise their
right to redeem such Shares and to send the proceeds to the Shareholder, the
Shareholder will be given notice that the value of the Shares in his or her
account is less than the minimum amount and will be allowed 60 days to make an
additional investment in an amount which will increase the value of the account
to at least $500.
 
  See "ADDITIONAL PURCHASE AND REDEMPTION INFORMATION--Matters Affecting
Redemption" in the Statement of Additional Information for examples of when the
Group may, under applicable law and regulation, suspend the right of redemption
if it appears appropriate to do so in light of the Group's responsibilities
under the 1940 Act.
 
                              DIVIDENDS AND TAXES
 
DIVIDENDS
 
  The Fixed Income Fund and Tax-Free Fund each intend to declare their net
investment income monthly as a dividend to Shareholders at the close of business
on the day of declaration. The U.S. Government Fund intends to declare its net
investment income daily as a dividend to Shareholders at the close of business
on the day of declaration. These Funds will generally pay such dividends
monthly. Each Fund also intends to distribute its capital gains, if any, at
least annually, normally in December of each year. The Equity Fund, the Balanced
Fund, the Aggressive Growth Fund and the Fixed Total Return Fund intend to
declare their net investment income quarterly as a dividend to Shareholders at
the close of business on the day of declaration, and generally will pay such
dividends quarterly. A Shareholder will automatically receive all income
dividends and capital gains distributions in additional full and fractional
Shares of a Fund at net asset value as of the date of payment, unless the
Shareholder elects to receive dividends or distributions in cash. Such election
must be made on the Account Application; any change in such election must be
made in writing to the Funds at 1900 East Dublin-Granville Road, Columbus, Ohio
43229, and will become effective with respect to dividends and distributions
having record dates after its receipt by the Transfer Agent. Dividends are paid
in cash not later than seven business days after a Shareholder's complete
redemption of his or her Shares.
 
FEDERAL TAXES
 
  The following discussion is intended for general information only. Investors
should consult with their tax adviser as to the tax consequences of an
investment in the Funds, including the status of distributions from the Funds
under applicable state or local law.
 
  Each Fund intends to qualify annually and elect to be treated as a regulated
investment company under the Internal Revenue Code of 1986, as
 
                                       28
<PAGE>   35
 
amended (the "Code"). To qualify, each Fund must meet certain income,
distribution and diversification requirements. In any year in which a Fund
qualifies as a regulated investment company and timely distributes all of its
income and substantially all of its net tax-exempt interest income, the Fund
generally will not pay any U.S. federal income or excise tax.
 
  Dividends that are distributed by a Fund that are derived from interest income
exempt from federal income tax and are designated by the Fund as
"exempt-interest dividends" will be exempt from regular federal income taxation.
However, if tax exempt interest earned by the Fund constitutes an item of tax
preference for purposes of the alternative minimum tax, then a portion of the
exempt-interest dividends paid by the Fund may likewise constitute an item of
tax preference. In addition, any exempt-interest dividends received by corporate
shareholders may constitute an adjustment to alternative minimum taxable income
for purposes of the alternative minimum tax and the environmental tax imposed
under Code Sections 55 and 59A, respectively. Only the Tax-Free Fund is expected
to be eligible to designate certain of its dividends as "exempt-interest
dividends."
 
  Exempt-interest dividends of a Fund, although exempt from regular federal
income tax, are includible in the tax base for determining the extent to which
Social Security and railroad benefits will be subject to federal income tax. All
shareholders are required to report the receipt of dividends and distributions,
including exempt-interest dividends, on their federal income tax returns.
 
  Dividends paid out of a Fund's investment company taxable income (including
dividends, taxable interest and net short-term capital gains) will be taxable to
a U.S. Shareholder as ordinary income. A portion of the Equity Fund, Balanced
Fund and Aggressive Growth Fund's income may consist of dividends paid by U.S.
corporations. Therefore, a portion of the dividends paid by these Funds may be
eligible for the corporate dividends-received deduction. Because no portion of
the other Funds' income is expected to consist of dividends paid by U.S.
corporations, no portion of the dividends paid by those Funds is expected to be
eligible for the corporate dividends-received deduction. Distributions of net
capital gains (the excess of net long-term capital gains over net short-term
capital losses), if any, designated by a Fund as capital gain dividends are
taxable as long-term capital gains, regardless of the length of time the
Shareholder has held a Fund's Shares. Dividends are generally treated in the
same manner whether received in cash or reinvested in additional Fund Shares.
 
  A distribution will be treated as paid on December 31 of the current calendar
year if it is declared by a Fund in October, November or December of that year
to shareholders of record on a date in such a month and paid by a Fund during
January of the following calendar year. Such distributions will be treated as
received by Shareholders in the calendar year in which the distributions are
declared, rather than the calendar year in which the distributions are received.
 
  Each year the Funds will notify Shareholders of the tax status of dividends
and distributions.
 
  Investments in securities that are issued at a discount will result each year
in income to a Fund equal to a portion of the excess of the face value of the
securities over their issue price, even though the Fund receives no cash
interest payments from the securities. Such income generally will, however, have
to be distributed to shareholders on a timely basis.
 
  A portion of the income earned by the Tax-Free Fund may be taxable rather than
tax-exempt. Accordingly, a portion of the dividends paid by the Tax-Free Fund
may be taxable to Shareholders.
 
  Any gain or loss realized by a Shareholder upon the sale or other disposition
of Shares of a Fund, or upon receipt of a distribution in complete liquidation
of a Fund, generally will be a taxable capital gain or loss which will be
long-term or short-term, generally depending upon the Shareholder's holding
period for the Shares. In some cases, Shareholders will not be permitted to take
sales charges into account in determining the amount of gain or loss
 
                                       29
<PAGE>   36
 
realized on the disposition of their shares. See "Additional Tax Information" in
the Statement of Additional Information.
 
  Shareholders should be aware that redeeming shares of the Tax-Free Fund after
tax-exempt interest income has been accrued by the Fund but before that income
has been declared as a dividend may be disadvantageous. This is because the
gain, if any, on the redemption will be taxable, even though such gain may be
attributable in part to the accrued tax-exempt interest which, if distributed to
the shareholder as a dividend rather than as redemption proceeds, might have
qualified as an exempt-interest dividend.
 
  The Funds may be required to withhold U.S. federal income tax at the rate of
31% of all reportable dividends (which does not include exempt-interest
dividends) and capital gain distributions (as well as redemptions for all Funds
except the U.S. Government Fund), payable to Shareholders who fail to provide
the Fund with their correct taxpayer identification number or to make required
certifications, or who have been notified by the IRS that they are subject to
backup withholding. Backup withholding is not an additional tax. Any amounts
withheld may be credited against the Shareholder's U.S. federal income tax
liability.
 
  Further information relating to tax consequences is contained in the Statement
of Additional Information.
 
STATE AND LOCAL TAXES
 
  The Group is organized as a Massachusetts business trust and, under current
law, neither the Group nor any Fund is liable for any income or franchise tax in
the Commonwealth of Massachusetts as long as each Fund qualifies as a regulated
investment company under the Code.
 
  Distributions from all of the Funds may be subject to state and local taxes.
Distributions of a Fund which are derived from interest on obligations of the
U.S. Government and certain of its agencies and instrumentalities may be exempt
from state and local taxes in certain states. In certain states, distributions
of the Tax-Free Fund which are derived from interest on obligations of that
state or its municipalities or any political subdivisions thereof may be exempt
from state and local taxes. Shareholders should consult their tax advisers
regarding the possible exclusion for state and local income tax
purposes of the portion of dividends paid by a Fund which is attributable to
interest from obligations of the U.S. Government and its agencies, authorities
and instrumentalities, and the particular tax consequences to them of an
investment in a Fund, including the application of state and local tax laws.
 
                            MANAGEMENT OF THE GROUP
 
TRUSTEES OF THE GROUP
 
  Overall responsibility for management of the Group rests with its Board of
Trustees, who are elected by the shareholders of the Group's funds. There are
currently five Trustees, of whom two are "interested persons" of the Group
within the meaning of that term under the 1940 Act. The Group will be managed by
the Trustees in accordance with the laws of Massachusetts governing business
trusts. The Trustees, in turn, elect the officers of the Group to supervise
actively its day-to-day operations.
 
  The Trustees receive fees and are reimbursed for their expenses in connection
with each meeting of the Board of Trustees they attend. However, no officer or
employee of Winsbury or BISYS Fund Services Ohio, Inc. receives any compensation
from the Group for acting as a Trustee of the Group. The officers of the Group
(see the Statement of Additional Information) receive no compensation directly
from the Group for performing the duties of their offices. Winsbury receives
fees from the Funds for acting as administrator. BISYS Fund Services Ohio, Inc.
receives fees from the Funds for acting as Transfer Agent and for providing
certain fund accounting services.

                       inception.
</TABLE>
 
  Subject to the general supervision of the Group's Board of Trustees and in
accordance with a Fund's investment objective and restrictions, AMCORE manages
the investments of a Fund, makes decisions with respect to and places orders for
all purchases and sales of a Fund's portfolio securities, and maintains a Fund's
records relating to such purchases and sales.
 
  For the services provided and expenses assumed pursuant to its investment
advisory agreement with the Group, AMCORE receives a fee computed daily and paid
monthly, at the annual rate of sixty one-hundredths of one percent (.60%) of
each of the Fixed Income Fund and the Tax-Free Fund's average daily net assets,
at the annual rate of forty one-hundredths of one percent (.40%) of the U.S.
Government Fund's average daily net assets, at the annual rate of seventy-five
one-hundredths of one percent (.75%) of each of the Equity Fund, the Fixed Total
Return Fund and the Balanced Fund's average daily net assets and at the annual
rate of ninety-five one-hundredths of one percent (.95%) of the Aggressive
Growth Fund's average daily net assets. Unlike advisory fees paid by most other
investment companies, these fees do not change as a result of the amount of
assets in a Fund. The investment advisory fees and administrative fees paid by
the Fixed Income Fund, Tax-Free Fund, Equity Fund, Balanced Fund, Aggressive
Growth Fund and Fixed Total Return Fund, absent fee waivers, are higher than
those paid by most other
 
                                       31
<PAGE>   38
 
investment companies. AMCORE may periodically waive all or a portion of its
advisory fee to increase the net income of a Fund available for distribution as
dividends. AMCORE may not seek reimbursement of such waived fees at a later
date. The waiver of such fee will cause the yield of a Fund to be higher than it
would otherwise be in the absence of such a waiver.
 
ADMINISTRATOR AND DISTRIBUTOR
 
  Winsbury is the administrator for the Funds and also acts as the Funds'
principal underwriter and distributor (the "Administrator" or the "Distributor,"
as the context indicates). Winsbury is wholly-owned by The BISYS Group, Inc. 150
Clove Road, Little Falls, New Jersey 07424, a publicly owned company engaged in
information processing, loan servicing and 401(k) administration and
recordkeeping services to and through banking and other financial organizations.
 
  The Administrator generally assists in all aspects of the Funds'
administration and operation. For expenses assumed and services provided as
administrator pursuant to its management and administration agreement with the
Funds, the Administrator receives a fee computed daily and paid periodically,
calculated at an annual rate of twenty one-hundredths of one percent (.20%) of
the Fund's average daily net assets. The Administrator may periodically waive
all or a portion of its administrative fee to increase the net income of a Fund
available for distribution as dividends. The Administrator may not seek
reimbursement of such waived fees at a later date. The waiver of such fee will
cause the yield of a Fund to be higher than it would otherwise be in the absence
of such a waiver.
 
  The Distributor acts as agent for the Funds in the distribution of their
Shares and, in such capacity, solicits orders for the sale of Shares,
advertises, and pays the costs of advertising, office space and its personnel
involved in such activities.
 
EXPENSES AND PORTFOLIO TRANSACTIONS
 
  AMCORE and the Administrator each bear all expenses in connection with the
performance of their services as investment adviser and general manager and
administrator, respectively, other than the cost of securities (including
brokerage commissions, if any) purchased for the Funds.
 
  The policy of each of the Funds, regarding purchases and sales of securities
for its portfolio, is that primary consideration be given to obtaining the most
favorable prices and efficient execution of transactions. In seeking to
implement the Fund's policies, AMCORE effects transactions with those brokers
and dealers whom AMCORE believes provide the most favorable prices and are
capable of providing efficient executions. If AMCORE believes such price and
executions are obtainable from more than one broker or dealer, it may give
consideration to placing portfolio transactions with those brokers and dealers
who also furnish research and other services to the Fund or AMCORE. Such
services may include, but are not limited to, any one or more of the following:
information as to the availability of securities for purchase or sale;
statistical or factual information or opinions pertaining to investments; wire
services; and appraisals or evaluations of portfolio securities. Such
information may be useful to AMCORE in serving both the Funds and other clients
and, conversely, supplemental information obtained by the placement of business
of other clients may be useful to AMCORE in carrying out its obligations to the
Funds.
 
  Subject to applicable limitations of the federal securities laws,
broker-dealers may receive commissions for agency transactions that are in
excess of the amount of commission charged by other broker-dealers in
recognition of their research or execution services. In order to cause the Funds
to pay such higher commissions, AMCORE must determine in good faith that such
commissions are reasonable in relation to the value of the brokerage and/or
research services provided by such executing broker-dealers, viewed in terms of
a particular transaction or AMCORE's overall responsibilities to the Funds. In
reaching this determination, AMCORE will not attempt to place a specific dollar
value on the brokerage and/or research services provided, or to determine what
portion of the compensation should be related to those services.

DISTRIBUTION PLAN
 
  Pursuant to Rule 12b-1 under the 1940 Act, the Group has adopted a
Distribution and Shareholder Service Plan (the "Plan"), under which each Fund is
authorized to pay or reimburse The Winsbury Company, as Distributor, a periodic
amount calculated at an annual rate not to exceed twenty-five one hundredths of
one percent (.25%) of the average daily net assets of the Fund. Such amount may
be used to pay banks (including AMCORE Bank) for administrative and shareholder
services and to pay broker-dealers and other institutions for similar services,
including distribution services (each such bank, broker-dealer and other
institution is hereafter referred to as a "Participating Organization"),
pursuant to an agreement between The Winsbury Company and the Participating
Organization. Under the Plan, a Participating Organization may include The
Winsbury Company, its subsidiaries and its affiliates.
 
  As authorized by the Plan, the Distributor has entered into a Rule 12b-1
Agreement with AMCORE Bank pursuant to which AMCORE Bank has agreed to provide
certain administrative and shareholder support services in connection with
Shares of a Fund purchased and held by AMCORE Bank for the accounts of its
Customers and Shares of a Fund purchased and held by Customers of AMCORE Bank
directly, including, but not limited to, processing automatic investments of
AMCORE Bank's Customer account cash balances in Shares of a Fund and
establishing and maintaining the systems, accounts and records necessary to
accomplish this service, establishing and maintaining Customer accounts and
records, processing purchase and redemption transactions for Customers,
answering routine Customer questions concerning the Funds and providing such
office space, equipment, telephone facilities and personnel as is necessary and
appropriate to accomplish such matters. In consideration of such services,
AMCORE Bank may receive a monthly fee, computed at the annual rate of
twenty-five one-hundredths of one percent (.25%) of the average aggregate net
asset value of the Shares of the Fund held during the period in Customer
accounts for which AMCORE Bank has provided services under this Agreement. The
Winsbury Company will be compensated by a Fund in an amount equal to any
payments it makes to AMCORE Bank under the Rule 12b-1 Agreement. Currently, it
is intended that no such amounts will be paid under the Plan or the Rule 12b-1
Agreement by any of the Funds.
 
ADMINISTRATIVE SERVICES PLAN
 
  The Group has adopted an Administrative Services Plan (the "Services Plan")
pursuant to which each Fund is authorized to pay compensation to banks and other
financial institutions (each a "Service Organization"), which may include the
Adviser, its correspondent and affiliated banks, and Winsbury, which agree to
provide certain ministerial, recordkeeping and/or administrative support
services for their customers or account holders (collectively, "customers") who
are the beneficial or record owner of Shares of that Fund. In consideration for
such services, a Service Organization receives a fee from a Fund, computed daily
and paid monthly, at an annual rate of up to .25% of the average daily net asset
value of Shares of that Fund owned beneficially or of record by such Service
Organization's customers for whom the Service Organization provides such
services.
 
  The servicing agreements adopted under the Services Plan (the "Servicing
Agreements") require the Service Organizations receiving such compensation to
perform certain ministerial, recordkeeping and/or administrative support
services with respect to the beneficial or record owners of Shares of the Funds,
such as processing dividend and distribution payments from the Fund on behalf of
customers, providing periodic statements to customers showing their positions in
the Shares of the Fund, providing sub-accounting with respect to Shares
beneficially owned by such customers and providing customers with a service that
invests the assets of their accounts in Shares of the Fund pursuant to specific
or pre-authorized instructions.
 
  As authorized by the Services Plan, the Group has entered into a Servicing
Agreement with an affiliate of the Adviser pursuant to which the affiliate has
agreed to provide certain administrative
 
                                       33
<PAGE>   40
 
support services in connection with Shares of the Funds owned of record or
beneficially by its customers. Such administrative support services may include,
but are not limited to, (i) processing dividend and distribution payments from a
Fund on behalf of customers, (ii) providing periodic statements to its customers
showing their positions in the Shares; (iii) arranging for bank wires; (iv)
responding to routine customer inquiries relating to services performed by the
affiliate; (v) providing sub-accounting with respect to the Shares beneficially
owned by the affiliate's customers or the information necessary for
sub-accounting; (vi) if required by law, forwarding shareholder communications
from a Fund (such as proxies, shareholder reports, annual and semi-annual
financial statements and dividend, distribution and tax notices) to its
customers; (vii) aggregating and processing purchase, exchange, and redemption
requests from customers and placing net purchase, exchange, and redemption
orders for customers; and (viii) providing customers with a service that invests
the assets of their account in the Shares pursuant to specific or pre-authorized
instructions. In consideration of such services, the Group, on behalf of each
Fund, has agreed to pay the affiliate a monthly fee, computed at an annual rate
of twenty-five one-hundredths of one percent (.25%) of the average aggregate net
asset value of Shares of that Fund held during the period by customers for whom
the affiliate has provided services under the Servicing Agreement.
 
CUSTODIAN
 
  The First National Bank of Chicago, One First National Plaza, Chicago,
Illinois 60670 (the "Custodian") serves as custodian for the Funds. Pursuant to
the Custodian Agreement with the Group, the Custodian receives compensation from
each Fund for such services in an amount equal to a designated annual fee plus
fixed fees charged for certain portfolio transactions and out-of-pocket
expenses.
 
TRANSFER AGENCY AND FUND ACCOUNTING SERVICES
 
  BISYS Fund Services Ohio, Inc. ("BISYS Fund Services" or the "Transfer
Agent"), an affiliate of Winsbury, 1900 East Dublin-Granville Road, Columbus,
Ohio 43229, serves as the Funds' transfer agent pursuant to a Transfer Agency
Agreement for the Funds and receives a fee for such services. BISYS Fund
Services also provides certain accounting services for the Funds pursuant to a
Fund Accounting Agreement and receives a fee for such services. See "MANAGEMENT
OF THE COMPANY--Transfer Agency and Fund Accounting Services" in the Statement
of Additional Information for further information.
 
  While BISYS Fund Services is a distinct legal
entity from The Winsbury Company (the Funds' Administrator and Distributor),
BISYS Fund Services is considered to be an affiliated person of The Winsbury
Company under the 1940 Act due to, among other things, the fact that BISYS Fund
Services is owned by substantially the same persons that directly or indirectly
own Winsbury.
 
BANKING LAWS
 
  AMCORE and AMCORE Bank believe that they possess the legal authority to
perform the advisory services and the administrative and shareholder support
services for the Funds contemplated by the investment advisory agreement and the
Rule 12b-1 Agreement, as described in this Prospectus, without violation of
applicable banking laws and regulations. Future changes in Federal or state
statutes and regulations relating to permissible activities of banks or bank
holding companies and their subsidiaries and affiliates as well as further
judicial or administrative decisions or interpretations of present and future
statutes and regulations could change the manner in which AMCORE or AMCORE Bank
could continue to perform such services for the Funds. It is not anticipated,
however, that any change in the Funds' method of operations would affect its net
asset value per share or result in financial losses to any Shareholder. See
"MANAGEMENT OF THE GROUP--Banking Laws" in the Statement of Additional
Information for further discussion of applicable law and regulations.

                              GENERAL INFORMATION
 
DESCRIPTION OF THE GROUP AND ITS SHARES
 
  The Group was organized as a Massachusetts business trust on January 8, 1992.
The Group consists of several funds organized as separate series of shares. Each
share represents an equal proportionate interest in a fund with other shares of
the same fund, and is entitled to such dividends and distributions out of the
income earned on the assets belonging to that fund as are declared at the
discretion of the Trustees (see "Miscellaneous" below).
 
  Shareholders are entitled to one vote for each full share held and a
proportionate fractional vote for any fractional shares held, and will vote in
the aggregate and not by series except as otherwise expressly required by law.
For example, shareholders of each fund will vote in the aggregate with other
shareholders of the Group with respect to the election of Trustees and
ratification of the selection of independent auditors. However, shareholders of
a particular fund will vote as a fund, and not in the aggregate with other
shareholders of the Group, for purposes of approval of that fund's investment
advisory agreement and the Plan.
 
  Overall responsibility for the management of the Funds is vested in the Board
of Trustees of the Group. See "MANAGEMENT OF THE GROUP--Trustees of the Group."
Individual Trustees are elected by the shareholders of the Group and may be
removed by the Board of Trustees or shareholders in accordance with the
provisions of the Declaration of Trust and By-Laws of the Group and
Massachusetts law. See "ADDITIONAL INFORMATION--Miscellaneous" in the Statement
of Additional Information for further information.
 
  An annual or special meeting of shareholders is not generally required by the
Declaration of Trust, the 1940 Act or other applicable authority. To the extent
that such a meeting is not required, the Group may elect not to have an annual
or special meeting.
 
  The Group has undertaken that the Trustees will call a special meeting of
shareholders for purposes of considering the removal of one or more Trustees
upon written request therefor from shareholders holding not less than 10% of the
outstanding votes of the Group. The Group will, to the extent required under the
1940 Act, assist Shareholders in calling such a meeting. At such a meeting, a
quorum of shareholders (constituting a majority of votes attributable to all
outstanding shares of the Group), by majority vote, has the power to remove one
or more Trustees.
 
  As of May 31, 1995, the Funds believe that AMCORE Trust Company indirectly
possessed or shared power to dispose of or vote with respect to more than 25% of
the outstanding shares of each of the Funds, except the U.S. Government Fund,
and therefore may be considered to be a controlling person of those Funds for
purposes of the Investment Company Act of 1940.
 
PERFORMANCE INFORMATION
 
  From time to time the Funds may advertise their average annual total return,
aggregate total return, yield and effective yield in advertisements, sales
literature and shareholder reports. SUCH PERFORMANCE FIGURES ARE BASED ON
HISTORICAL EARNINGS AND ARE NOT INTENDED TO INDICATE FUTURE PERFORMANCE. Average
annual total return will be calculated for the period since the establishment of
the Fund and will reflect the imposition of the maximum sales charge. Average
annual total return is measured by comparing the value of an investment in the
Fund at the beginning of the relevant period to the redemption value of the
investment at the end of the period (assuming immediate reinvestment of any
dividends or capital gains distributions) and annualizing the difference.
Aggregate total return is calculated similarly to average annual total return
except that the return figure is aggregated over the relevant period instead of
annualized. Yield for each of the Variable NAV Funds will be computed by
dividing the Fund's net investment
 
                                       35
<PAGE>   42
 
income per share earned during a recent one-month period by the Fund's per share
maximum offering price (reduced by any undeclared earned income expected to be
paid shortly as a dividend) on the last day of the period and annualizing the
result.
 
  The yield of the U.S. Government Fund refers to the income generated by an
investment therein over a seven-day period (which period will be stated in the
advertisement). This income is then "annualized." That is, the amount of income
generated by the investment during that week is assumed to be generated each
week over an annual period and is shown as a percentage of the investment. The
effective yield is calculated similarly but, when annualized, the income earned
by an investment in the U.S. Government Fund is assumed to be reinvested weekly.
The effective yield is slightly higher than the yield because of the compounding
effect of this assumed reinvestment.
 
  Distribution rates will be computed by dividing the distribution per share
made by the Fund over a twelve-month period by the maximum offering price per
share. The distribution rate includes both income and capital gain dividends and
does not reflect unrealized gains or losses. The distribution rate differs from
the yield, because it includes capital items which are often non-recurring in
nature, whereas yield does not include such items.
 
  The Tax-Free Fund may also present its tax equivalent yield and tax equivalent
effective yield which reflect the amount of income subject to federal income
taxation that a taxpayer would have to earn in order to obtain the same
after-tax income as that derived from the yield and effective yield,
respectively, of the Tax-Free Fund. The tax equivalent yield and tax equivalent
effective yield will be significantly higher than the yield and effective yield
of the Tax-Free Fund.
 
  Investors may also judge the performance of the Fund by comparing its
performance to the performance of other mutual funds or mutual fund portfolios
with comparable investment objectives and policies through various mutual fund
or market indices and to data prepared by various services which may be
published by such services or by other services or publications. In addition to
performance information, general information about the Fund that appears in such
publications may be included in advertisements, sales literature and in reports
to Shareholders.
 
  Yield and total return are functions of the type and quality of instruments
held in the portfolio, operating expenses, and market conditions. Consequently,
current yields and total return will fluctuate and are not necessarily
representative of future results. Any fees charged by AMCORE Bank or any of its
affiliates with respect to customer accounts for investing in shares of the
Funds will not be included in performance calculations; such fees, if charged,
will reduce the actual performance from that quoted.
 
  Additional information regarding the investment performance of the Funds is
contained in the annual report of the Funds which may be obtained without charge
by writing or calling the Funds.
 
MISCELLANEOUS
 
  Shareholders will receive unaudited semi-annual reports and annual reports
audited by independent auditors.
 
  As used in this Prospectus and in the Statement of Additional Information,
"assets belonging to a fund" means the consideration received by the fund upon
the issuance or sale of shares in that fund, together with all income, earnings,
profits, and proceeds derived from the investment thereof, including any
proceeds from the sale, exchange, or liquidation of such investments, and any
funds or amounts derived from any reinvestment of such proceeds, and any general
assets of the Group not readily identified as belonging to a particular fund
that are allocated to the Fund by the Group's Board of Trustees. The Board of
Trustees may allocate such general assets in any manner it deems fair and
equitable. Determinations by the Board of Trustees of the Group as to the timing
of the allocation of general liabilities and expenses and as to the timing and
allocable portion of any general assets with respect to the Fund are conclusive.

  As used in this Prospectus and in the Statement of Additional Information, a
"vote of a majority of the outstanding Shares" of a Fund means the affirmative
vote, at a meeting of Shareholders duly called, of the lesser of (a) 67% or more
of the votes of Shareholders of a Fund present at a meeting at which the holders
of more than 50% of the votes attributable to Shareholders of record of the Fund
are represented in person or by proxy, or (b) the holders of more than 50% of
the outstanding votes of Shareholders of a Fund.
 
  Inquiries regarding the Funds may be directed in writing to the Funds at 1900

               The Coventry Group (the "Group") is an open-end management
          investment company  which issues its Shares in separate series.
          Each series of Shares relates to a separate portfolio of assets.
          The portfolios advised by AMCORE Capital Management, Inc.
          ("AMCORE") are each referred to generally as a "Fund".  This

          upon subjects discussed in the Prospectus of the Funds.
          Capitalized terms not defined herein are defined in such
          Prospectus.  No investment in Shares of a Fund should be made
          without first reading the Prospectus.  References to the
          "Variable NAV Funds" shall mean all of the Funds except the U.S.
          Government Fund.

                          INVESTMENT OBJECTIVE AND POLICIES

          Additional Information on Portfolio Instruments
          -----------------------------------------------

               The following policies supplement the investment objective
          and policies of the Funds as set forth in their respective

               BANK OBLIGATIONS.  The Fixed Income Fund, Tax-Free Fund and
          the Balanced Fund may invest in bank obligations such as bankers'
          acceptances, certificates of deposit, and time deposits.

               Bankers' acceptances are negotiable drafts or bills of
          exchange typically drawn by an importer or exporter to pay for
          specific merchandise, which are "accepted" by a bank, meaning, in
          effect, that the bank unconditionally agrees to pay the face
          value of the instrument on maturity.  Bankers' acceptances
          invested in by the Funds will be those guaranteed by domestic and
          foreign banks having, at the time of investment, capital,
          surplus, and undivided profits in excess of $100,000,000 (as of
          the date of their most recently published financial statements).

               Certificates of deposit are negotiable certificates issued
          against funds deposited in a commercial bank or a savings and
          loan association for a definite period of time and earning a
          specified return.  Certificates of deposit and time deposits will
          be those of domestic and foreign banks and savings and loan
          associations, if (a) at the time of investment the depository
          institution has capital, surplus, and undivided profits in excess
          of $100,000,000 (as of the date of its most recently published
<PAGE>   50





          financial statements), or (b) the principal amount of the
          instrument is insured in full by the Federal Deposit Insurance
          Corporation.

               COMMERCIAL PAPER.  Commercial paper consists of unsecured
          promissory notes issued by corporations.  Issues of commercial
          paper normally have maturities of less than nine months and fixed
          rates of return.

               The Fixed Income Fund and the Tax-Free Fund may purchase
          commercial paper consisting of issues rated at the time of
          purchase within the two highest rating categories by a nationally
          recognized statistical rating organization (an "NRSRO").  The
          Balanced Fund may purchase commercial paper consisting of issues
          rated at the time of purchase within the three highest rating
          categories by an NRSRO.  The Fixed Total Return Fund may purchase
          commercial paper consisting of issues rated at the time of
          purchase within the four highest rating categories by an NRSRO.
          These Funds may also invest in commercial paper that is not rated
          but is determined by AMCORE under guidelines established by the
          Group's Board of Trustees, to be of comparable quality.

               VARIABLE AMOUNT MASTER DEMAND NOTES.  Variable amount master
          demand notes, in which the Fixed Income Fund, the Fixed Total
          Return Fund, the Balanced Fund and the Tax-Free Fund may invest,
          are unsecured demand notes that permit the indebtedness
          thereunder to vary and provide for periodic readjustments in the
          interest rate according to the terms of the instrument.  They are
          also referred to as variable rate demand notes.  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 or during specified
          periods not exceeding one year, depending upon the instrument
          involved, and may resell the note at any time to a third party.
          AMCORE will consider the earning power, cash flow, and other
          liquidity ratios of the issuers of such notes and will continu-
          ously monitor their financial status and ability to meet payment
          on demand.  In determining dollar-weighted average portfolio
          maturity, a variable amount master demand note will be deemed to
          have a maturity equal to the longer of the period of time remain-
          ing 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 NOTES.  The Tax-Free Fund, the
          Fixed Total Return Fund, the Balanced Fund and the Fixed Income
          Fund may acquire variable and floating rate notes, subject to
          such Fund's investment objective, policies and restrictions.  A
          variable rate note is one whose terms provide for the



                                        - 2 -

          readjustment of its interest rate on set dates and which, upon
          such readjustment, 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 readjustment 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 a Fund will be determined by AMCORE under
          guidelines approved by the Group'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, AMCORE 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.  Although there may be no active secondary
          market with respect to a particular variable or floating rate
          note purchased by a Fund, the Fund may resell the note any time
          to a third party.  The absence of an active secondary market,
          however, could make it difficult for the Fund to dispose of a
          variable or floating rate note in the event the issuer of the
          note defaulted on its payment obligations and the Fund could, as
          a result or for other reasons, suffer a loss to the extent of the
          default.  Variable or floating rate notes may be secured by bank
          letters of credit.

               U.S. GOVERNMENT OBLIGATIONS.  The U.S. Government Fund will
          invest exclusively in short-term U.S. Treasury bills, notes and
          other obligations issued or guaranteed by the U.S. Government or
          its agencies or instrumentalities subject to its investment
          objective and policies (collectively, "U.S. Government
          Obligations").  The Variable NAV Funds may also invest in U.S.
          Government Obligations.  Obligations of certain agencies and
          instrumentalities of the U.S. Government are supported by the
          full faith and credit of the U.S. Treasury; others are supported
          by the right of the issuer to borrow from the Treasury; others
          are supported by the discretionary authority of the U.S.
          Government to purchase the agency's obligations; and still others
          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 agencies or
          instrumentalities if it is not obligated to do so by law.  A Fund
          will invest in the obligations of such agencies or
          instrumentalities only when AMCORE believes that the credit risk
          with respect thereto is minimal.

               STRIPPED TREASURY SECURITIES.  The Variable NAV Funds may
          invest in certain U.S. Government Obligations referred to as
          "Stripped Treasury Securities."  Stripped Treasury Securities are



                                    - 3 -
<PAGE>   52





          U.S. Treasury securities that have been stripped of their
          unmatured interest coupons (which typically provide for interest
          payments semi-annually), interest coupons that have been stripped
          from such U.S. Treasury securities, and receipts and certificates
          for such stripped debt obligations and stripped coupons.
          Stripped bonds and stripped coupons are sold at a deep discount
          because the buyer of those securities receives only the right to
          receive a future fixed payment on the security and does not
          receive any rights to periodic interest payments on the security.

               Stripped Treasury Securities will include coupons that have
          been stripped from U.S. Treasury bonds, which may be held through
          the Federal Reserve Bank's book-entry system called "Separate
          Trading of Registered Interest and Principal of Securities"
          ("STRIPS") or through a program entitled "Coupon Under Book-Entry
          Safekeeping" ("CUBES").

               The U.S. Government does not issue Stripped Treasury
          Securities directly.  The STRIPS program, which is ongoing, is
          designed to facilitate the secondary market in the stripping of
          selected U.S. Treasury notes and bonds into separate interest and
          principal components.  Under the program, the U.S. Treasury
          continues to sell its notes and bonds through its customary
          auction process.  A purchaser of those specified notes and bonds
          who has access to a book-entry account at a Federal Reserve bank,
          however, may separate the Treasury notes and bonds into interest
          and principal components.  The selected Treasury securities
          thereafter may be maintained in the book-entry system operated by
          the Federal Reserve in a manner that permits the separate trading
          and ownership of the interest and principal payments.

               CUBES, like STRIPS, are direct obligations of the U.S.
          Government.  CUBES are coupons that have previously been
          physically stripped from U.S. Treasury notes and bonds, but which
          were deposited with the Federal Reserve Bank's book-entry system
          and are now carried and transferable in book-entry form only.
          Only stripped U.S. Treasury coupons maturing on or after January
          15, 1988, that were stripped prior to January 5, 1987, were
          eligible for conversion to book-entry form under the CUBES
          program.

               By agreement, the underlying debt obligations will be held
          separate from the general assets of the custodian and nominal
          holder of such securities, and will not be subject to any right,
          charge, security interest, lien or claim of any kind in favor of
          or against the custodian or any person claiming through the
          custodian, and the custodian will be responsible for applying all
          payments received on those underlying debt obligations to the
          related receipts or certificates without making any deductions
          other than applicable tax withholding.  The custodian is required



                                        - 4 -
<PAGE>   53





          to maintain insurance for the protection of holders of receipts
          or certificates in customary amounts against losses resulting
          from the custody arrangement due to dishonest or fraudulent
          action by the custodian's employees.  The holders of receipts or
          certificates, as the real parties in interest, are entitled to
          the rights and privileges of the underlying debt obligations,
          including the right, in the event of default in payment of
          principal or interest to proceed individually against the issuer
          without acting in concert with other holders of those receipts or
          certificates or the custodian.

               FOREIGN INVESTMENTS.  The Equity Fund, the Fixed Income
          Fund, the Fixed Total Return Fund, the Balanced Fund and the
          Aggressive Growth Fund may, subject to their respective
          investment objectives and policies, invest in certain obligations
          or securities of foreign issuers.  Permissible investments
          include American Depository Receipts ("ADRs") for the Equity
          Fund, the Balanced Fund and the Aggressive Growth Fund and Yankee
          Obligations (as described in the Prospectus) for the Fixed Income
          Fund, the Fixed Total Return Fund, the Balanced Fund and the
          Aggressive Growth Fund.  Investment in securities issued by
          foreign branches of U.S. banks, foreign banks, or other foreign
          issuers, including ADRs may subject such Funds to investment
          risks that differ in some respects from those related to
          investment in obligations of U.S. domestic issuers.  Such risks
          include future adverse political and economic developments,
          possible seizure, nationalization, or expropriation of foreign
          investments, less stringent disclosure requirements, the possible
          establishment of exchange controls or taxation at the source or
          other taxes, and the adoption of other foreign governmental
          restrictions.

               Additional risks include less publicly available
          information, the risk that companies may not be subject to the
          accounting, auditing and financial reporting standards and
          requirements of U.S. companies, the risk that foreign securities
          markets may have less volume and therefore many securities traded
          in these markets may be less liquid and their prices more
          volatile than U.S. securities, and the risk that custodian and
          brokerage costs may be higher.  Foreign issuers of securities or
          obligations are often subject to accounting treatment and engage
          in business practices different from those respecting domestic
          issuers of similar securities or obligations.  Foreign branches
          of U.S. banks and foreign banks may be subject to less stringent
          reserve requirements than those applicable to domestic branches
          of U.S. banks.

               CALL OPTIONS.  The Equity Fund, the Balanced Fund and the
          Aggressive Growth Fund may write (sell) "covered" call options
          and purchase options to close out options previously written by



                                        - 5 -
<PAGE>   54





          them.  Such options must be listed on a National Securities
          Exchange and issued by the Options Clearing Corporation.  The
          purpose of writing covered call options is to generate additional
          premium income for a Fund.  This premium income will serve to
          enhance the Fund's total return and will reduce the effect of any
          price decline of the security involved in the option.  Covered
          call options will generally be written on securities which, in
          AMCORE's opinion, are not expected to make any major price moves
          in the near future but which, over the long term, are deemed to
          be attractive investments for a Fund.

               A call option gives the holder (buyer) the "right to
          purchase" a security at a specified price (the exercise price) at
          any time until a certain date (the expiration date).  So long as
          the obligation of the writer of a call option continues, he may
          be assigned an exercise notice by the broker-dealer through whom
          such option was sold, requiring him to deliver the underlying
          security against payment of the exercise price.  This obligation
          terminates upon the expiration of the call option, or such
          earlier time at which the writer effects a closing purchase
          transaction by repurchasing an option identical to that
          previously sold.  To secure his obligation to deliver the
          underlying security in the case of a call option, a writer is
          required to deposit in escrow the underlying security or other
          assets in accordance with the rules of the Options Clearing
          Corporation.  A Fund will write only covered call options.  (In
          order to comply with the requirements of the securities laws in
          several states, a Fund will not write a covered call option if,
          as a result, the aggregate market value of all portfolio
          securities covering all call options exceeds 15% of the market
          value of its net assets.)

               Fund securities on which call options may be written will be
          purchased solely on the basis of investment considerations
          consistent with a Fund's investment objective.  The writing of
          covered call options is a conservative investment technique
          believed to involve relatively little risk (in contrast to the
          writing of naked or uncovered options, which the Funds will not
          do), but capable of enhancing a Fund's total return.  When
          writing a covered call option, a Fund, in return for the premium,
          gives up the opportunity for profit from a price increase in the
          underlying security above the exercise price, but retains the
          risk of loss should the price of the security decline.  Unlike
          one who owns securities not subject to an option, a Fund has no
          control over when it may be required to sell the underlying
          securities, since it may be assigned an exercise notice at any
          time prior to the expiration of its obligation as a writer.  If a
          call option which a Fund has written expires, the Fund will
          realize a gain in the amount of the premium; however, such gain
          may be offset by a decline in the market value of the underlying



                                        - 6 -
<PAGE>   55





          security during the option period.  If the call option is
          exercised, the Fund will realize a gain or loss from the sale of
          the underlying security.  The security covering the call will be
          maintained in a segregated account of a Fund's Custodian.  The
          Funds do not consider a security covered by a call to be
          "pledged" as that term is used in each Fund's policy which limits
          the pledging or mortgaging of its assets.

               The premium received is the market value of an option.  The
          premium a Fund will receive from writing a call option will
          reflect, among other things, the current market price of the
          underlying security, the relationship of the exercise price to
          such market price, the historical price volatility of the
          underlying security, and the length of the option period.  Once
          the decision to write a call option has been made, AMCORE, in
          determining whether a particular call option should be written on
          a particular security, will consider the reasonableness of the
          anticipated premium and the likelihood that a liquid secondary
          market will exist for such option.  The premium received by a
          Fund for writing covered call options will be recorded as a
          liability in the Fund's statement of assets and liabilities.
          This liability will be adjusted daily to the option's current
          market value, which will be the latest sale price at the time at
          which the net asset value per share of a Fund is computed (close
          of the New York Stock Exchange), or, in the absence of such sale,
          the latest asked price.  The liability will be extinguished upon
          expiration of the option, the purchase of an identical option in
          a closing transaction, or delivery of the underlying security
          upon the exercise of the option.

               Closing transactions will be effected in order to realize a
          profit on an outstanding call option, to prevent an underlying
          security from being called, or to permit the sale of the
          underlying security.  Furthermore, effecting a closing
          transaction will permit a Fund to write another call option on
          the underlying security with either a different exercise price or
          expiration date or both.  If a Fund desires to sell a particular
          security from its portfolio on which it has written a call
          option, it will seek to effect a closing transaction prior to, or
          concurrently with, the sale of the security.  There is, of
          course, no assurance that a Fund will be able to effect such
          closing transactions at a favorable price.  If a Fund cannot
          enter into such a transaction, it may be required to hold a
          security that it might otherwise have sold, in which case it
          would continue to be at market risk on the security.  This could
          result in higher transaction costs.  The Funds will pay
          transaction costs in connection with the writing of options to
          close out previously written options.  Such transaction costs are
          normally higher than those applicable to purchases and sales of
          portfolio securities.



                                        - 7 -
<PAGE>   56





               Call options written by a Fund will normally have expiration
          dates of less than nine months from the date written.  The
          exercise price of the options may be below, equal to, or above
          the current market values of the underlying securities at the
          time the options are written.  From time to time, a Fund may
          purchase an underlying security for delivery in accordance with
          an exercise notice of a call option assigned to it, rather than
          delivering such security from its portfolio.  In such cases,
          additional costs will be incurred.

               A Fund will realize a profit or loss from a closing purchase
          transaction if the cost of the transaction is less or more than
          the premium received from the writing of the option.  Because
          increases in the market price of a call option will generally
          reflect increases in the market price of the underlying security,
          any loss resulting from the repurchase of a call option is likely
          to be offset in whole or in part by appreciation of the
          underlying security owned by the Fund.

               PUT OPTIONS.  The Tax-Free Fund may acquire "puts" with
          respect to Municipal Securities held in its portfolio and the
          Fixed Income Fund, the Fixed Total Return Fund and the Balanced
          Fund may acquire "puts" with respect to debt securities held in
          their portfolio.  A put is a right to sell or redeem a specified
          security (or securities) at a certain time or within a certain
          period of time at a specified exercise price.  The put may be an
          independent feature or may be combined with a reset feature that
          is designed to reduce downward price volatility as interest rates
          rise by enabling the holder to liquidate the investment prior to
          maturity.

               The amount payable to a Fund upon its exercise of a "put" is
          normally (i) the Fund's acquisition cost of the securities
          subject to the put (excluding any accrued interest which the Fund
          paid on the 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.

               Puts may be acquired by a Fund to facilitate the liquidity
          of the portfolio assets.  Puts may also be used to facilitate
          that reinvestment of assets at a rate of return more favorable
          than that of the underlying security.  Puts may, under certain
          circumstances, also be used to shorten the maturity of underlying
          variable rate or floating rate securities for purposes of
          calculating the remaining maturity of those securities and the
          dollar-weighted average portfolio maturity of a Fund's assets.

               The Tax-Free Fund, the Fixed Income Fund, the Fixed Total
          Return Fund and the Balanced Fund will, if necessary or
          advisable, pay for puts either separately in cash or by paying a
          higher price for portfolio securities which are acquired subject
          to the puts (thus reducing the yield to maturity otherwise
          available for the same securities).

               WHEN-ISSUED SECURITIES.  As discussed in the Prospectuses of
          the Funds, each of the Funds may purchase securities on a when-
          issued or delayed-delivery basis.  When-issued securities are
          securities purchased for delivery beyond the normal settlement
          date at a stated price and yield and thereby involve a risk that
          the yield obtained in the transaction will be less than those
          available in the market when delivery takes place.  A Fund will
          generally not pay for such securities or start earning interest
          on them until they are received.  When a Fund agrees to purchase
          securities on a when-issued basis, the Custodian will set 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 the purchase
          commitment, and in such a case, the Fund may be required subse-
          quently to place additional assets in the separate account in
          order to assure that the value of the account remains equal to
          the amount of the Fund's commitment.  It may be expected that the
          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.  In addition, because a Fund will
          set aside cash or liquid portfolio securities to satisfy its
          purchase commitments in the manner described above, the Fund's
          liquidity and the ability of AMCORE to manage it might be
          affected in the event its commitments to purchase when-issued
          securities ever exceeded 25% of the value of its total assets.

               When a Fund engages in when issued transactions, it relies
          on the seller to consummate the trade.  Failure of the seller to
          do so may result in the Fund incurring a loss or missing the
          opportunity to obtain a price considered to be advantageous.  The
          Funds will engage in when issued delivery transactions only for
          the purpose of acquiring portfolio securities consistent with the
          Funds' investment objectives and policies, not for investment
          leverage.

               MORTGAGE-RELATED SECURITIES.  The Fixed Income Fund, the
          Fixed Total Return Fund and the Balanced Fund may, consistent
          with their respective investment objectives and policies, invest
          in mortgage-related securities issued or guaranteed by the U.S.
          Government or its agencies or instrumentalities.  Mortgage-
          related securities, for purposes of the Prospectus and this
          Statement of Additional Information, represent pools of mortgage
          loans assembled for sale to investors by various governmental



                                        - 9 -

          agencies such as the Government National Mortgage Association and
          government-related organizations such as the Federal National
          Mortgage Association and the Federal Home Loan Mortgage
          Corporation, as well as by nongovernmental issuers such as
          commercial banks, savings and loan institutions, mortgage bankers
          and private mortgage insurance companies.  Although certain
          mortgage-related securities are guaranteed by a third party or
          otherwise similarly secured, the market value of the security,
          which may fluctuate, is not so secured.  If a Fund purchases a
          mortgage-related security at a premium, that portion may be lost
          if there is a decline in the market value of the security whether
          resulting from changes in interest rates or prepayments in the
          underlying mortgage collateral.  As with other interest-bearing
          securities, the prices of such securities are inversely affected
          by changes in interest rates.  However, though the value of a
          mortgage-related security may decline when interest rates rise,
          the converse is not necessarily true, since in periods of
          declining interest rates the mortgages underlying the securities
          are prone to prepayment, thereby shortening the average life of
          the security and shortening the period of time over which income
          at the higher rate is received.  Conversely, when interest rates
          are rising, the rate of prepayment tends to decrease, thereby
          lengthening the average life of the security and lengthening the
          period of time over which income at the lower rate is received.
          For these and other reasons, a mortgage-related security's
          average maturity may be shortened or lengthened as a result of
          interest rate fluctuations and, therefore, it is not possible to
          predict accurately the security's return to the Fund.  In
          addition, regular payments received in respect of mortgage-
          related securities include both interest and principal.  No
          assurance can be given as to the return a Fund will receive when
          these amounts are reinvested.

               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 issued by the Government
          National Mortgage Association ("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 Develop-
          ment.  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-related securities issued by the
          Federal National Mortgage Association ("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



                                        - 10 -
<PAGE>   59





          United States.  The FNMA is a government-sponsored organization
          owned entirely by private stockholders.  Fannie Maes are
          guaranteed as to timely payment of the principal and interest by
          FNMA.  Mortgage-related securities issued by the Federal Home
          Loan Mortgage Corporation ("FHLMC") include FHLMC Mortgage
          Participation Certificates (also known as "Freddie Macs" or
          "PCs").  The FHLMC is a corporate instrumentality of the United
          States, created pursuant to an Act of Congress, which is owned
          entirely by Federal Home Loan Banks.  Freddie Macs are not
          guaranteed by the United States or by any Federal Home Loan Banks
          and do not constitute a debt or obligation of the United States
          or of any Federal Home Loan Bank.  Freddie Macs entitle the
          holder to timely payment of interest, which is guaranteed by the
          FHLMC.  The FHLMC guarantees either ultimate collection or timely
          payment of all principal payments on the underlying mortgage
          loans.  When the 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.

               The Fixed Income Fund, the Fixed Total Return Fund and the
          Balanced Fund may also invest in mortgage-related securities
          which are collateralized mortgage obligations ("CMOs") structured
          on pools of mortgage pass-through certificates or mortgage loans.
          The CMOs in which these Funds may invest represent securities
          issued by a private corporation or a U.S. Government
          instrumentality that are backed by a portfolio of mortgages or
          mortgage-backed securities held under an indenture.  The issuer's
          obligations to make interest and principal payments is secured by
          the underlying portfolio of mortgages or mortgage-backed
          securities.  CMOs are issued with a number of classes or series
          which have different maturities and which may represent interests
          in some or all of the interest or principal on the underlying
          collateral or a combination thereof.  CMOs of different classes
          are generally retired in sequence as the underlying mortgage
          loans in the mortgage pool are repaid.  In the event of
          sufficient early prepayments on such mortgages, the class or
          series of a CMO first to mature generally will be retired prior
          to its maturity.  Thus, the early retirement of a particular
          class or series of a CMO held by a Fund would have the same
          effect as the prepayment of mortgages underlying a mortgage-
          backed pass-through security.  Mortgage-related securities will
          be purchased only if rated within the three highest bond rating
          categories assigned by an NRSRO or, if unrated, which AMCORE
          deems to present attractive opportunities and are of comparable
          quality.

               OTHER ASSET-BACKED SECURITIES.  The Fixed Income Fund and
          the Fixed Total Return Fund may also invest in interests in pools



                                        - 11 -
<PAGE>   60





          of receivables, such as motor vehicle installment purchase
          obligations (known as Certificates of Automobile Receivables or
          CARSSM) and credit card receivables (known as Certificates of
          Amortizing Revolving Debts or CARDSSM).  Such securities are
          generally issued as pass-through certificates, which represent
          undivided fractional ownership interests in the underlying pools
          of assets.  Such securities may also be debt instruments which
          are also known as collateralized obligations and are generally
          issued as the debt of a special purpose entity organized solely
          for the purpose of owning such assets and issuing such debt.

               Such securities are not issued or guaranteed by the U.S.
          Government or its agencies or instrumentalities; however, the
          payment of principal and interest on such obligations may be
          guaranteed up to certain amounts and for a certain time period by
          a letter of credit issued by a financial institution (such as a
          bank or insurance company) unaffiliated with the issuers of such
          securities.  Non-mortgage backed securities will be purchased by
          the Fixed Income Fund only when rated within the three highest
          rating categories by an NRSRO at the time of purchase.  In
          addition, such securities generally will have remaining estimated
          lives at the time of purchase of 7 years or less.

               SECURITIES OF OTHER INVESTMENT COMPANIES.  Each Fund, except
          the U.S. Government Fund, may invest in securities issued by the
          other investment companies, including Shares of the U.S.
          Government Fund.  Each of these Funds currently intends to limit
          its investments so that, as determined immediately after a
          securities purchase is made:  (a) not more than 5% of the value
          of its total assets will be invested in the securities of any one
          investment company; (b) 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; (c) not more than 3% of the
          outstanding voting stock of any one investment company will be
          owned by any of the Funds; and (d) not more than 10% of the
          outstanding voting stock of any one investment company will be
          owned in the aggregate by the Funds.  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 the Fund bears directly in
          connection with its own operations.  In order to avoid the
          imposition of additional fees as a result of investing in Shares
          of the U.S. Government Fund, AMCORE and the Administrator will
          waive any portion of their usual service fees that are
          attributable to investments therein by another Fund.  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




                                        - 12 -

          charges will be payable by the Funds and, therefore, will be
          borne directly by Shareholders.

               REPURCHASE AGREEMENTS.  Securities held by each Fund may be
          subject to repurchase agreements.  Under the terms of a
          repurchase agreement, a Fund would acquire securities from member
          banks of the Federal Deposit Insurance Corporation and registered
          broker-dealers which AMCORE deems creditworthy under guidelines
          approved by the Group'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 would generally
          equal the price paid by the Fund plus interest negotiated on the
          basis of current short-term rates, which may be more or less than
          the rate on the underlying portfolio securities.  The seller
          under a repurchase agreement will be required to maintain
          continually the value of collateral held pursuant to the
          agreement at not less than the repurchase price (including
          accrued interest).  If the seller were to default on its
          repurchase obligation or become insolvent, the Fund holding such
          obligation would suffer a loss to the extent that the proceeds
          from a sale of the underlying portfolio securities were less than
          the repurchase price under the agreement, or to the extent that
          the disposition of such securities by the Fund were delayed
          pending court action.  Additionally, 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, although the
          Board of Trustees of the Group 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 Group if
          presented with the question.  Securities subject to repurchase
          agreements will be held by that Fund'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.  As discussed in the
          Prospectuses, each Fund may borrow funds for temporary purposes
          by entering into reverse repurchase agreements in accordance with
          that Fund's 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 the securities at a mutually agreed-upon date and
          price.  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 continually



                                        - 13 -
<PAGE>   62





          monitor the account to ensure that such equivalent value is
          maintained at all times.  Reverse repurchase agreements involve
          the risk that the market value of the securities sold by a Fund
          may decline below the price at which a Fund is obligated to
          repurchase the securities.  Reverse repurchase agreements are
          considered to be borrowings by a Fund under the 1940 Act.

               MUNICIPAL SECURITIES.  Under normal market conditions, at
          least 80% of the net assets of the Tax-Free Fund will be invested
          in Municipal Securities, the interest on which is exempt from the
          regular federal income tax and not treated as a preference item
          for purposes of the federal alternative minimum tax imposed on
          non-corporate taxpayers.

               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 Municipal Securities if the interest paid thereon is exempt
          from regular federal individual income taxes and is not treated
          as a preference item for purposes of the federal alternative
          minimum tax.

               Other types of Municipal Securities which the Tax-Free Fund
          may purchase are short-term General Obligation Notes, Tax
          Anticipation Notes, Bond Anticipation Notes, Revenue Anticipation
          Notes, Tax-Exempt Commercial Paper, Project Notes, 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 Tax-Free Fund will not purchase municipal
          lease obligations.

               Project Notes are issued by a state or local housing agency
          and are sold by the Department of Housing and Urban Development.
          While the issuing agency has the primary obligation with respect
          to its Project Notes, they are also secured by the full faith and
          credit of the United States through agreements with the issuing
          authority which provide that, if required, the federal government
          will lend the issuer an amount equal to the principal of and
          interest on the Project Notes.

               As described in the Prospectus, the two principal
          classifications of Municipal Securities consist of "general
          obligation" and "revenue" issues.  The Tax-Free Fund may also
          acquire "moral obligation" issues, which are normally issued by



                                        - 14 -
<PAGE>   63





          special purpose authorities.  There are, of course, variations in
          the quality of Municipal Securities, both within a particular
          classification and between classifications, and the yields on
          Municipal Securities depend upon a variety of factors, including
          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 Moody's and S&P represent
          their opinions as to the quality of Municipal Securities.  It
          should be emphasized, however, that ratings are general and are
          not absolute standards of quality, and securities with the same
          maturity, interest rate and rating may have different yields,
          while securities of the same maturity and interest rate with
          different ratings may have the same yield.  Subsequent to
          purchase, an issue of Municipal Securities may cease to be rated
          or its rating may be reduced below the minimum rating required
          for purchase by the Tax-Free Fund.  AMCORE will consider such an
          event in determining whether the Fund should continue to hold the
          obligation.

               An issuer's obligations for 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 for the payment of interest on
          and principal of its Municipal Securities may be materially
          adversely affected by litigation or other conditions.

          Investment Restrictions
          -----------------------

               The following are fundamental investment restrictions and
          are in addition to the investment restrictions set forth in the
          Prospectus.  Under these restrictions a Fund may not:

               1.   Underwrite securities issued by other persons, except
          to the extent that a Fund may be deemed to be an underwriter
          under certain securities laws in the disposition of "restricted
          securities";

               2.   Purchase or sell commodities or commodities contracts,
          except to the extent disclosed in the current Prospectus of the
          Funds;

               3.   Purchase or sell real estate (although investments by
          the Equity Fund and the Fixed Income Fund in marketable




                                        - 15 -
<PAGE>   64





          securities of companies engaged in such activities are not
          prohibited by this restriction);

               The following additional investment restrictions are not
          fundamental and may be changed with respect to a particular Fund
          without the vote of a majority of the outstanding Shares of that
          Fund.  A Fund may not:

               1.   Enter into repurchase agreements with maturities in
          excess of seven days if such investments, together with other
          instruments in that Fund that are not readily marketable or are
          otherwise illiquid, exceed 15% of that Fund's total assets.

               2.   Purchase securities on margin, except for use of short-
          term credit necessary for clearance of purchases of portfolio
          securities;

               3.   Engage in any short sales;

               4.   Purchase participation or direct interests in oil, gas
          or other mineral exploration or development programs (although
          investments by the Equity Fund and the Fixed Income Fund in
          marketable securities of companies engaged in such activities are
          not prohibited in this restriction);

               5.   Purchase securities of other investment companies,
          except (a) in connection with a merger, consolidation,
          acquisition or reorganization, and (b) a Fund may invest in other
          investment companies, including other Funds for which AMCORE acts
          as adviser, as specified in the Prospectus subject to such
          restrictions as may be imposed by the 1940 Act or any state laws.

               6.   Invest more than 5% of total assets in puts, calls,
          straddles, spreads or any combination thereof.

               7.   With respect to the Equity Fund, the Balanced Fund, the
          Aggressive Growth Fund, the Fixed Total Return Fund, and the
          Fixed Income Fund, invest more than 5% of total assets in
          securities of issuers which together with any predecessors have a
          record of less than three years continuous operation.

               If any percentage restriction described above is satisfied
          at the time of investment, a later increase or decrease in such
          percentage resulting from a change in asset value will not
          constitute a violation of such restriction.

          Portfolio Turnover
          ------------------

               The portfolio turnover rate for each of the Funds is
          calculated by dividing the lesser of a Fund's purchases or sales



                                        - 16 -
<PAGE>   65





          of portfolio securities for the year by the monthly average value
          of the portfolio securities.  The calculation excludes all
          securities whose remaining maturities at the time of acquisition
          were one year or less.

               For the fiscal year ended March 31, 1995 the annual turnover
          rate of the Equity Fund was 20.54%, the annual turnover rate of
          the Fixed Income Fund was 32.38%, and the annual turnover rate of
          the Tax-Free Fund was 5.77%.  It is presently estimated that the
          annual turnover rate of the Balanced Fund will generally not
          exceed 80%, that the annual turnover rate of the Aggressive
          Growth Fund will generally not exceed 75%, and that the annual
          turnover rate of the Fixed Total Return Fund will generally not
          exceed 100%.  However, portfolio turnover for any of the Funds
          may vary greatly from year to year as well as within a particular
          year.  High turnover rates will generally result in higher
          transaction costs to a Fund.  Portfolio turnover will not be a
          limiting factor in making investment decisions.

               Because the U.S. Government Fund intends to invest entirely
          in securities with maturities of less than one year and because
          the Commission requires such securities to be excluded from the
          calculation of the portfolio turnover rate, the portfolio
          turnover with respect to the U.S. Government Fund is expected to
          be zero percent for regulatory purposes.

                                   NET ASSET VALUE

               As indicated in the Prospectuses, the net asset value of
          each Fund is determined and the Shares of each Fund are priced as
          of the Valuation Times applicable to such Fund on each Business
          Day of the Company.  A "Business Day" constitutes any day on
          which the New York Stock Exchange (the "NYSE") is open for
          trading, the Federal Reserve Bank of Chicago is open, and any
          other day except days on which there are not sufficient changes
          in the value of the Fund's portfolio securities that the Fund's
          net asset value might be materially affected and days during
          which no Shares are tendered for redemption and no orders to
          purchase Shares are received.  Currently, either the NYSE or
          Federal Reserve Bank of Chicago are closed on New Year's Day,
          Martin Luther King, Jr. Day, President's Day, Good Friday,
          Memorial Day, Independence Day, Labor Day, Columbus Day,
          Veteran's Day, Thanksgiving Day and Christmas Day.

          Valuation of the U.S. Government Fund
          -------------------------------------

               The U.S. Government Fund has elected to use the amortized
          cost method of valuation pursuant to Rule 2a-7 under the 1940
          Act.  This involves valuing an instrument at its cost initially
          and thereafter assuming a constant amortization to maturity of



                                        - 17 -
<PAGE>   66





          any discount or premium, regardless of the impact of fluctuating
          interest rates on the market value of the instrument.  This
          method may result in periods during which value, as determined by
          amortized cost, is higher or lower than the price the U.S.
          Government Fund would receive if it sold the instrument.  The
          value of securities in the U.S. Government Fund can be expected
          to vary inversely with changes in prevailing interest rates.

               Pursuant to Rule 2a-7, the U.S. Government Fund will
          maintain a dollar-weighted average portfolio maturity appropriate
          to the Fund's objective of maintaining a stable net asset value
          per share, provided that the Fund will not purchase securities
          with a remaining maturity of more than 397 days (thirteen months)
          (securities subject to repurchase agreements may bear longer
          maturities) nor maintain a dollar-weighted average portfolio
          maturity which exceeds 90 days.  The Group's Board of Trustees
          has also undertaken to establish procedures reasonably designed,
          taking into account current market conditions and the investment
          objective of the Fund, to 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 Trustees, at such
          intervals as they deem 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, Rule 2a-7 requires that the Board of Trustees
          promptly consider what action, if any, should be initiated.  If
          the Trustees believe 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 new or existing
          investors, they will take such steps as they consider 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, reducing
          the number of the U.S. Government Fund's outstanding Shares
          without monetary consideration, or utilizing a net asset value
          per share determined by using available market quotations.

          Valuation of the Variable NAV Funds
          -----------------------------------

               Portfolio securities for which market quotations are readily
          available are valued based upon their current available bid
          prices in the principal market (closing sales prices if the
          principal market is an exchange) in which such securities are
          normally traded.  Unlisted securities for which market quotations
          are readily available will be valued at the current quoted bid
          prices.  Other securities and assets for which quotations are not
          readily available, including restricted securities and securities
          purchased in private transactions, are valued at their fair value



                                        - 18 -

          in AMCORE's best judgement under the supervision of the Group's
          Board of Trustees.

               Among the factors that will be considered, if they apply, in
          valuing portfolio securities held by the Variable NAV Funds are
          the existence of restrictions upon the sale of the security by
          the Fund, the absence of a market for the security, the extent of
          any discount in acquiring the security, the estimated time during
          which the security will not be freely marketable, the expenses of
          registering or otherwise qualifying the security for public sale,
          underwriting commissions if underwriting would be required to
          effect a sale, the current yields on comparable securities for
          debt obligations traded independently of any equity equivalent,
          changes in the financial condition and prospects of the issuer,
          and any other factors affecting fair value.  In making
          valuations, opinions of counsel may be relied upon as to whether
          or not securities are restricted securities and as to the legal
          requirements for public sale.

               The Group may use a pricing service to value certain
          portfolio securities where the prices provided are believed to
          reflect the fair market value of such securities.  A pricing
          service would normally consider such factors as yield, risk,
          quality, maturity, type of issue, trading characteristics,
          special circumstances and other factors it deems relevant in
          determining valuations of normal institutional trading units of
          debt securities and would not rely exclusively on quoted prices.
          The methods used by the pricing service and the valuations so
          established will be reviewed by the Group under the general
          supervision of the Group's Board of Trustees.  Several pricing
          services are available, one or more of which may be used by the
          Adviser from time to time.

                    ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

          Matters Affecting Redemption
          ----------------------------
   

               Shares in each of the Group's Funds are sold on a continuous
          basis by BISYS Fund Services Limited Partnership d/b/a BISYS Fund
          Services (the "Distributor") and BISYS Fund Services has agreed
          to use appropriate efforts to solicit all purchase orders.  In
          addition to purchasing Shares directly from the Distributor,
          Shares may be purchased through procedures established by BISYS
          Fund Services in connection with the requirements of accounts at
          AMCORE Bank, N.A., ("AMCORE Bank") or AMCORE Bank's affiliated
          entities (collectively, "Banks").  Customers purchasing Shares of
          the Funds may include officers, directors, or employees of the
          Banks.

               The Group may suspend the right of redemption or postpone
          the date of payment for Shares during any period when (a) trading
          on the New York Stock Exchange (the "Exchange") is restricted by
          applicable rules and regulations of the Commission, (b) the
          Exchange is closed for other than customary weekend and holiday
          closings, (c) the Commission has by order permitted such
          suspension for the protection of security holders of the Group,
          or (d) the Commission has determined that an emergency exists as
          a result of which (i) disposal by the Group of securities owned
          by it is not reasonably practical, or (ii) it is not reasonably
          practical for the Group to determine the fair value of its net
          assets.

               The Group may redeem Shares of each of the Funds
          involuntarily if redemption appears appropriate in light of the
          Group's responsibilities under the 1940 Act.  See "NET ASSET
          VALUE" in this Statement of Additional Information.

Investment Adviser
- ------------------

        Investment advisory services are provided by AMCORE Capital Management,
Inc., Rockford, Illinois, pursuant to an Investment Advisory Agreement dated as
of December 1, 1992 (the "Investment Advisory Agreement").

        Under the Investment Advisory Agreement, the Adviser has agreed to
provide investment advisory services as described in the Prospectus of the
Funds.  For the services provided pursuant to the Investment Advisory Agreement,
each of the Funds pays AMCORE a fee computed daily and paid monthly, at an
annual rate, calculated as a percentage of the average daily net assets of that
Fund, of sixty one-hundredths of one percent (.60%) for both the Fixed Income
Fund and the Tax-Free Fund, of forty one- hundredths of one percent (.40%) for
the U.S. Government Fund, of seventy-five one-hundredths of one percent (.75%)
for the Equity Fund and the Balanced Fund and ninety-five one-hundredths of one
percent (.95%) for the Aggressive Growth Fund.  AMCORE may periodically waive
all or a portion of its advisory fee with respect to any Fund to increase the
net income of the Fund available for distribution as dividends.

        The total investment advisory fees paid to AMCORE for the last three
fiscal years is as follows:

         U.S. Government Fund - for the fiscal year ended March 31, 1993
(covering the period from the commencement of operations on December 21, 1992
through March 31, 1993), AMCORE earned investment advisory fees of $21,111 and
AMCORE waived or assumed advisory fees in the amount of $65,897; for the fiscal

               Tax-Free Fund - for the fiscal year ended March 31, 1993
          (covering the period from commencement of operations on February
          16, 1993 through March 31, 1993), AMCORE earned investment
          advisory fees of $0 and AMCORE waived or assumed advisory fees in
          the amount of $8,400; for the fiscal year ended March 31, 1994

               Equity Fund - for the fiscal year ended March 31, 1993
          (covering the period from commencement of operations on December

               Unless sooner terminated, the Investment Advisory Agreement
          will continue in effect as to each Fund until January 31, 1996
          and from year to year thereafter, if such continuance is approved
          at least annually by the Group's Board of Trustees or by vote of
          a majority of the outstanding Shares of the relevant Fund (as
          defined under "GENERAL INFORMATION - Miscellaneous" in the Funds'
          Prospectus), and a majority of the Trustees who are not parties
          to the Investment Advisory Agreement or interested persons (as
          defined in the 1940 Act) of any party to the Investment Advisory
          Agreement by votes cast in person at a meeting called for such
          purpose.  The Investment Advisory Agreement is terminable as to a

                                        - 25 -
<PAGE>   74





          Fund at any time on 60 days' written notice without penalty by
          the Trustees, by vote of a majority of the outstanding Shares of
          that Fund, or by AMCORE.  The Investment Advisory Agreement also
          terminates automatically in the event of any assignment, as
          defined in the 1940 Act.

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

          Portfolio Transactions
          ----------------------

               Pursuant to the Investment Advisory Agreement, AMCORE
          determines, subject to the general supervision of the Board of
          Trustees of the Group and in accordance with each Fund's
          investment objective and restrictions, which securities are to be
          purchased and sold by a Fund, and which brokers are to be
          eligible to execute such Fund's portfolio transactions.
          Purchases and sales of portfolio securities with respect to the
          Funds usually are principal transactions in which portfolio
          securities are normally purchased directly from the issuer or
          from an underwriter or market maker for the securities.
          Purchases from underwriters of portfolio securities generally
          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.  Transac-
          tions on stock exchanges involve the payment of negotiated
          brokerage commissions.  Transactions in the over-the-counter
          market are generally principal transactions with dealers.  With
          respect to the over-the-counter market, AMCORE, where possible,
          will deal directly with dealers who make a market in the securi-
          ties involved except in those circumstances where better price
          and execution are available elsewhere.
   
               The Group, on behalf of the Funds, will not execute
          portfolio transactions through, acquire portfolio securities
          issued by, make savings deposits in, or enter into repurchase or
          reverse repurchase agreements with AMCORE, AMCORE Bank, the
          Distributor, or their affiliates, and will not give preference to
          AMCORE's correspondents with respect to such transactions,
          securities, savings deposits, repurchase agreements, and reverse
          repurchase agreements.

               Investment decisions for each Fund are made independently
          from those for the other Funds or any other investment company or
          account managed by AMCORE.  Any such other Fund, investment
          company or account may also invest in the same securities as the
          Group on behalf of the Funds.  When a purchase or sale of the
          same security is made at substantially the same time on behalf of
          more than one Fund or a Fund and another investment company or
          account, the transaction will be averaged as to price, and avail-
          able investments will be allocated as to amount in a manner which
          AMCORE believes to be equitable to the Fund(s) and such other
          investment company or account.  In some instances, this
          investment procedure may adversely affect the price paid or
          received by a Fund or the size of the position obtained by a
          Fund.  To the extent permitted by law, AMCORE may aggregate the
          securities to be sold or purchased for a Fund with those to be
          sold or purchased for the other Funds or for other investment
          companies or accounts in order to obtain best execution.  As
          provided by the Investment Advisory Agreement, in making invest-
          ment recommendations for the Funds, AMCORE will not inquire or
          take into consideration whether an issuer of securities proposed
          for purchase or sale by the Funds is a customer of AMCORE its
          parent or its subsidiaries or affiliates and, in dealing with its
          customers, AMCORE, its parent, subsidiaries, and affiliates will
          not inquire or take into consideration whether securities of such
          customers are held by the Funds.

               For the fiscal years ended March 31, 1993, 1994 and 1995,
          only the Equity Fund paid any brokerage commissions, which
          commissions amounted to $44,302, $126,766 and $132,486,
          respectively.  None of such commissions were paid to any
          affiliate of the Funds, AMCORE or AMCORE Bank.

          Banking Laws
          ------------

               AMCORE and AMCORE Bank believe that it possesses the legal
          authority to perform the services for the Funds contemplated by
          the Prospectus, this Statement of Additional Information, the
          Investment Advisory Agreement, and Rule 12b-1 Agreement described
          below without violation of applicable statutes and regulations.
          AMCORE and AMCORE Bank have been advised by its counsel that,
          while the question is not free from doubt, such laws should not
          prevent AMCORE and AMCORE Bank from providing the services
          required of it under the Investment Advisory Agreement and Rule
          12b-1 Agreement.  Future changes in either federal or state
          statutes and regulations relating to the permissible activities
          of banks or bank holding companies and the subsidiaries or
          affiliates of those entities, as well as further judicial or
          administrative decisions or interpretations of present and future
          statutes and regulations, could prevent or restrict AMCORE or
          AMCORE Bank from continuing to perform such services for the



                                        - 27 -
<PAGE>   76





          Funds.  Depending upon the nature of any changes in the services
          which could be provided by AMCORE or AMCORE Bank the Board of
          Trustees of the Group would review the Funds' relationship with
          AMCORE or AMCORE Bank and consider taking all action necessary in
          the circumstances.

               Should future legislative, judicial, or administrative
          action prohibit or restrict the proposed activities of AMCORE and
          AMCORE Bank and/or its affiliated and correspondent banks in
          connection with Customer purchases of Shares of the Funds, those
          banks might be required to alter materially or discontinue the
          services offered by them to Customers.  It is not anticipated,
          however, that any change in the Group's method of operations
          would affect its net asset value per share or result in financial
          losses to any Customer.

          Administrator
          -------------
   
               BISYS Fund Services serves as administrator (the
          "Administrator") to the Funds pursuant to a Management and
          Administration Agreement dated November 10, 1992 (the
          "Administration Agreement").  The Administrator assists in
          supervising all operations of each Fund (other than those per-
          formed by the Adviser under the Investment Advisory Agreement,
          the Custodian under the Custodian Agreement and by BISYS Fund
          Services Ohio under the Transfer Agency Agreement and Fund
          Accounting Agreement).  The Administrator is a broker-dealer
          registered with the Commission, and is a member of the National
          Association of Securities Dealers, Inc.  The Administrator
          provides financial services to institutional clients.
    
               Under the Administration Agreement, the Administrator has
          agreed to maintain office facilities; furnish statistical and
          research data, clerical, certain bookkeeping services and
          stationery and office supplies; prepare the periodic reports to
          the Commission on Form N-SAR or any replacement forms therefor;
          compile data for, prepare for execution by the Funds and file all
          of the Funds' federal and state tax returns and required tax
          filings other than those required to be made by the Funds'
          Custodian and Transfer Agent; prepare compliance filings pursuant
          to state securities laws with the advice of the Group's counsel;
          assist to the extent requested by the Funds with the Fund's
          preparation of its Annual and Semi-Annual Reports to Shareholders
          and its Registration Statement; compile data for, prepare and
          file timely Notices to the Commission required pursuant to Rule
          24f-2 under the 1940 Act; keep and maintain the financial
          accounts and records of each Fund, including calculation of daily
          expense accruals; and generally assists in all aspects of the
          Funds' operations other than those performed by AMCORE under the
          Investment Advisory Agreement, by the Custodian under the



                                        - 28 -
<PAGE>   77





          Custodian Agreement and by BISYS Fund Services Ohio, Inc. under
          the Transfer Agency Agreement and Fund Accounting Agreement.
          Under the Administration Agreement, the Administrator may
          delegate all or any part of its responsibilities thereunder.

               The Administrator receives a fee from each Fund for its
          services as Administrator and expenses assumed pursuant to the
          Administration Agreement, equal to the lesser of (1) a fee
          calculated daily and paid periodically, at the annual rate equal
          to twenty one-hundredths of one percent (.20%) of that Fund's
          average daily net assets or (2) such other fee as may be agreed
          upon in writing by the Group and the Administrator.  The
          Administrator may periodically waive all or a portion of its fee
          with respect to any Fund in order to increase the net income of

          renewed automatically for successive five-year terms, unless
          written notice not to renew is given by the non-renewing party to
          the other party at least 60 days prior to the expiration of the
          then-current term.  The Administration Agreement is terminable
          with respect to a particular Fund only upon mutual agreement of
          the parties to the Administration Agreement and for cause (as
          defined in the Administration Agreement) by the party alleging

          matters to which the Administration Agreement relates, except a
          loss resulting from willful misfeasance, bad faith, or gross
          negligence in the performance of its duties, or from the reckless
          disregard by the Administrator of its obligations and duties
          thereunder.

          Expenses
          --------

               If total expenses borne by any of the Funds in any fiscal
          year exceed expense limitations imposed by applicable state
          securities regulations, AMCORE and the Administrator will
          reimburse that Fund by the amount of such excess in proportion to
          their respective fees.  As of the date of this Statement of
          Additional Information, the only expense limitation applicable to
          each of the Funds limits its aggregate annual expenses, including
          management and advisory fees but excluding interest, taxes,
          distribution fees, brokerage commissions, and certain other



                                        - 30 -

          expenses, to 2 1/2% of the first $30 million of that Fund's
          average net assets, 2% of the next $70 million of that Fund's
          average net assets, and 1/2% of that Fund's remaining average net
          assets.  Any expense exceeding applicable limitations will be
          estimated daily and reconciled and waived or returned on a
          monthly basis.  Fees imposed upon customer accounts by AMCORE or
          its affiliated or correspondent banks for cash management
          services are not included within Fund expenses for purposes of
          any such expense limitation.

          Distributor
          -----------
   
               BISYS Fund Services serves as distributor to the Funds
          pursuant to the Distribution Agreement dated April 3, 1992, (the
          "Distribution Agreement").  Unless otherwise terminated, the
          Distribution Agreement will continue in effect until January 31,
          1996, and from year to year thereafter if such continuance is
          approved at least annually (i) by the Group's Board of Trustees
          or by the vote of a majority of the outstanding Shares of the
          Funds and (ii) by the vote of a majority of the Trustees of the
          Group who are not parties to the Distribution Agreement or
          interested persons (as defined in the 1940 Act) of any party to
          the Distribution Agreement, cast in person at a meeting called
          for the purpose of voting on such approval.  The Distribution
          Agreement may be terminated in the event of any assignment, as
          defined in the 1940 Act.

               In its capacity as Distributor, BISYS Fund Services solicits
          orders for the sale of Shares, advertises and pays the costs of
          advertising, office space and the personnel involved in such
          activities.  The Distributor receives no compensation under the
          Distribution Agreement with the Group, but may receive
          compensation under the Distribution and Shareholder Service Plan
          described below.
    
               The Distributor received $4,459 in commissions on the Equity
          Fund for the period from December 15, 1992 (commencement of
          operations) to March 31, 1993, of which it retained $423 after
          dealer allowances.  The Distributor received no commissions on
          sales of the Fixed Income or Tax-Free Fund for the period from
          commencement of operations to March 31, 1993.  The Distributor
          received $23,750 in commissions on the Equity Fund for the fiscal
          year ended March 31, 1994, of which it retained $4,541 after
          dealer reallowances.  The Distributor received no commissions on
          sales of the Fixed Income or Tax-Free Fund for the fiscal year
          ended March 31, 1994.  The Distributor received $30,080 in
          commissions on the Equity Fund for the fiscal year ended
          March 31, 1995, of which it retained $5,751 after dealer
          reallowances.  The distributor received no commissions on sales

          of the Fixed Income or Tax-Free Fund for the fiscal year ended
          March 31, 1995.
   
               As described in the Prospectus, the Group has adopted a
          Distribution and Shareholder Service Plan (the "Plan") pursuant
          to Rule 12b-1 under the 1940 Act under which the Funds are
          authorized to pay the Distributor for payments it makes to banks,
          including AMCORE Bank, other institutions and broker-dealers, and
          for expenses the Distributor and any of its affiliates or
          subsidiaries incur (with all of the foregoing organizations being
          referred to as "Participating Organizations") for providing
          administration, distribution or shareholder service assistance.
          Payments to such Participating Organizations may be made pursuant
          to agreements entered into with the Distributor.  The Plan
          authorizes the Funds to make payments to the Distributor in an
          amount not to exceed, on an annual basis, 0.25% of the average
          daily net assets of a Fund.  As required by Rule 12b-1, the Plan
          was approved by the sole Shareholder of each Fund and by the
          Board of Trustees, including a majority of the Trustees who are
          not interested persons of the Funds and who have no direct or
          indirect financial interest in the operation of the Plan (the
          "Independent Trustees").  The Plan may be terminated with respect
          to a Fund by vote of a majority of the Independent Trustees, or
          by vote of a majority of the outstanding Shares of the Fund.  The
          Trustees review quarterly a written report of such costs and the
          purposes for which such costs have been incurred.  The Plan may
          be amended by vote of the Trustees including a majority of the
          Independent Trustees, cast in person at a meeting called for that
          purpose.  However, any change in the Plan that would materially
          increase the distribution cost to a Fund requires Shareholder
          approval.  For so long as the Plan is in effect, selection and
          nomination of the Independent Trustees shall be committed to the
          discretion of such disinterested persons.  All agreements with
          any person relating to the implementation of the Plan may be
          terminated, with respect to a Fund, at any time on 60 days'
          written notice without payment of any penalty, by vote of a
          majority of the Independent Trustees or by vote of a majority of
          the outstanding Shares of the Fund.  The Plan will continue in
          effect for successive one-year periods, provided that each such
          continuance is specifically approved (i) by the vote of a
          majority of the Independent Trustees, and (ii) by the vote of a
          majority of the entire Board of Trustees cast in person at a
          meeting called for that purpose.  The Board of Trustees has a
          duty to request and evaluate such information as may be
          reasonably necessary for it to make an informed determination of
          whether the Plan should be implemented or continued.  In addition
          the Trustees in approving the Plan must determine that there is a
          reasonable likelihood that the Plan will benefit each Fund and
          its Shareholders.

               The Board of Trustees of the Group believes that the Plan is
          in the best interests of each of the Funds since it encourages
          Fund growth.  As a Fund grows in size, certain expenses, and
          therefore total expenses per Share, may be reduced and overall
          performance per Share may be improved.

               As authorized by the Plan, the Distributor has entered into
          a Rule 12b-1 Agreement with AMCORE Bank pursuant to which AMCORE
          Bank has agreed to provide certain administrative and shareholder
          support services in connection with Shares of the Funds purchased
          and held by AMCORE Bank for the accounts of its Customers and
          Shares of the Fund purchased and held by Customers of AMCORE Bank
          directly, including, but not limited to, processing automatic
          investments of AMCORE Bank's Customer account cash balances in
          Shares of a Fund and establishing and maintaining the systems,
          accounts and records necessary to accomplish this service,
          establishing and maintaining Customer accounts and records,
          processing purchase and redemption transactions for Customers,
          answering routine Customer questions concerning the Funds and
          providing such office space, equipment, telephone and personnel
          as is necessary and appropriate to accomplish such matters.  In
          consideration of such services the Distributor has agreed to pay
          AMCORE Bank a monthly fee, computed at the annual rate of .25% of
          the average aggregate net asset value of Shares of the Funds held
          during the period in Customer accounts for which AMCORE Bank has
          provided services under this Agreement.  The Distributor will be
          compensated by each Fund in an amount equal to its payments to
          AMCORE Bank with respect to each Fund's Shares under the Rule
          12b-1 Agreement.

               For the fiscal year ended March 31, 1995, as the result of a
          voluntary fee waiver by the Distributor, no distribution fees
          were paid by the Funds.

          Administrative Services Plan
          ----------------------------
   
               The Group has adopted an Administrative Services Plan (the
          "Services Plan") pursuant to which each Fund is authorized to pay
          compensation to banks and other financial institutions (each a
          "Service Organization"), which may include the Adviser, its
          correspondent and affiliated banks, and the Distributor, which
          agree to provide certain ministerial, recordkeeping and/or
          administrative support services for their customers or account
          holders (collectively, "customers") who are the beneficial or
          record owner of Shares of that Fund.  In consideration for such
          services, a Service Organization receives a fee from a Fund,
          computed daily and paid monthly, at an annual rate of up to .25%
          of the average daily net asset value of Shares of that Fund owned
          beneficially or of record by such Service Organization's
    



                                        - 33 -
<PAGE>   82





          customers for whom the Service Organization provides such
          services.

               The servicing agreements adopted under the Services Plan
          (the "Servicing Agreements") require the Service Organizations
          receiving such compensation to perform certain ministerial,
          recordkeeping and/or administrative support services with respect
          to the beneficial or record owners of Shares of the Funds, such
          as processing dividend and distribution payments from the Fund on
          behalf of customers, providing periodic statements to customers
          showing their positions in the Shares of the Fund, providing sub-
          accounting with respect to Shares beneficially owned by such
          customers and providing customers with a service that invests the
          assets of their accounts in Shares of the Fund pursuant to
          specific or pre-authorized instructions.

               As authorized by the Services Plan, the Group has entered
          into Servicing Agreements with the Adviser pursuant to which the
          Adviser has agreed to provide certain administrative support
          services in connection with Shares of the Funds owned of record
          or beneficially by its customers.  Such administrative support
          services may include, but are not limited to, (i) processing
          dividend and distribution payments from a Fund on behalf of
          customers, (ii) providing periodic statements to its customers
          showing their positions in the Shares; (iii) arranging for bank
          wires; (iv) responding to routine customer inquiries relating to
          services performed by the Adviser; (v) providing sub-accounting
          with respect to the Shares beneficially owned by the Adviser's
          customers or the information necessary for sub-accounting; (vi)
          if required by law, forwarding shareholder communications from a
          Fund (such as proxies, shareholder reports, annual and semi-
          annual financial statements and dividend, distribution and tax
          notices) to its customers; (vii) aggregating and processing
          purchase, exchange, and redemption requests from customers and
          placing net purchase, exchange, and redemption orders for
          customers; and (viii) providing customers with a service that
          invests the assets of their account in the Shares pursuant to
          specific or pre-authorized instructions.  In consideration of
          such services, the Group, on behalf of each Fund, has agreed to
          pay the Adviser a monthly fee, computed at an annual rate of
          twenty-five one-hundredths of one percent (.25%) of the average
          aggregate net asset value of Shares of that Fund held during the
          period by customers for whom the Adviser has provided services
          under the Servicing Agreement.

          Custodian
          ---------

               The First National Bank of Chicago serves as custodian (the
          "Custodian") to the Funds pursuant to the Custodian Agreement
          dated as of July 15, 1994, between the Group and the Custodian



                                        - 34 -

          include safeguarding and controlling each Fund's cash and
          securities, handling the receipt and delivery of securities, and
          collecting interest on each Fund's investments.  In consideration
          of such services, each of the Funds pays the Custodian an annual
          fee plus fixed fees charged for certain portfolio transactions
          and out-of-pocket expenses.

               Unless sooner terminated, the Custodian Agreement will
          continue in effect until terminated by either party upon 60 days'
          advance written notice to the other party.  Notwithstanding the
          foregoing, the Custodian Agreement, with respect to a Fund, must
          be approved at least annually by the Group's Board of Trustees or
          by vote of a majority of the outstanding Shares of that Fund (as
          defined under "GENERAL INFORMATION - Miscellaneous" in the
          Prospectus), and a majority of the Trustees who are not parties
          to the Custodian Agreement or interested persons (as defined in
          the 1940 Act) of any party to the Custodian Agreement
          ("Disinterested Persons") by votes cast in person at a meeting
          called for such purpose.

          Independent Auditors
          --------------------

                                ADDITIONAL INFORMATION

          Description of Shares
          ---------------------

               The Group is a Massachusetts business trust, organized on
          January 8, 1992.  The Group's Declaration of Trust is on file
          with the Secretary of State of Massachusetts.  The Declaration of
          Trust authorizes the Board of Trustees to issue an unlimited
          number of shares, which are shares of beneficial interest, with a
          par value of $0.01 per share.  The Group consists of several
          funds organized as separate series of shares.  The Group's
          Declaration of Trust authorizes the Board of Trustees to divide
          or redivide any unissued shares of the Group into one or more
          additional series by setting or changing in any one or more
          respects their respective preferences, conversion or other
          rights, voting power, restrictions, limitations as to dividends,
          qualifications, and terms and conditions of redemption.

               Shares have no subscription or 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 Prospectuses and this Statement of Additional Information,
          the shares will be fully paid and non-assessable.  In the event
          of a liquidation or dissolution of the Group, shareholders of a
          fund are entitled to receive the assets available for
          distribution belonging to that fund, and a proportionate
          distribution, based upon the relative asset values of the
          respective funds, of any general assets not belonging to any
          particular fund which are available for distribution.

               Rule 18f-2 under the 1940 Act provides that any matter
          required to be submitted to the holders of the outstanding voting
          securities of an investment company such as the Group shall not
          be deemed to have been effectively acted upon unless approved by
          the holders of a majority of the outstanding Shares of each Fund
          affected by the matter.  For purposes of determining whether the
          approval of a majority of the outstanding Shares of a Fund will
          be required in connection with a matter, a Fund will be deemed to
          be affected by a matter unless it is clear that the interests of
          each Fund in the matter are identical, or that the matter does
          not affect any interest of the Fund.  Under Rule 18f-2, the
          approval of an investment advisory agreement or any change in
          investment policy would be effectively acted upon with respect to
          a Fund only if approved by a majority of the outstanding Shares
          of such Fund.  However, Rule 18f-2 also provides that the
          ratification of independent public accountants, the approval of
          principal underwriting contracts, and the election of Trustees
          may be effectively acted upon by Shareholders of the Group voting
          without regard to series.

               Under Massachusetts law, shareholders could, under certain
          circumstances, be held personally liable for the obligations of
          the Group.  However, the Declaration of Trust disclaims liability
          of the Shareholders, Trustees or officers of the Group for acts
          or obligations of the Group, which are binding only on the assets
          and property of the Group, and requires that notice of the
          disclaimer be given in each contract or obligation entered into
          or executed by the Group or the Trustees.  The Declaration of
          Trust provides for indemnification out of Group property for all
          loss and expense of any shareholder held personally liable for
          the obligations of the Group.  The risk of a shareholder
          incurring financial loss on account of shareholder liability is
          limited to circumstances in which the Group itself would be
          unable to meet its obligations, and thus should be considered
          remote.

          Vote of a Majority of the Outstanding Shares
          --------------------------------------------

               As used in the Prospectus and this Statement of Additional
          Information, a "vote of a majority of the outstanding Shares" of
          a Fund means the affirmative vote, at a meeting of Shareholders
          duly called, of the lesser of (a) 67% or more of the votes of
          Shareholders of that Fund present at a meeting at which the
          holders of more than 50% of the votes attributable to
          Shareholders of record of that Fund are represented in person or
          by proxy, or (b) the holders of more than 50% of the outstanding
          votes of Shareholders of that Fund.

          Additional Tax Information
          --------------------------

               TAXATION OF THE FUNDS.  Each Fund intends to qualify
          annually and to elect to be treated as a regulated investment
          company under the Internal Revenue Code of 1986, as amended (the
          "Code").

               To qualify as a regulated investment company, each Fund
          must, among other things, (a) derive in each taxable year at
          least 90% of its gross income from dividends, interest, payments
          with respect to securities loans and gains from the sale or other
          disposition of stock, securities or foreign currencies or other
          income derived with respect to its business of investing in such
          stock, securities or currencies; (b) derive less than 30% of its
          gross income from the sale or other disposition of certain assets
          (namely, in the case of a Fund, (i) stock or securities, (ii)
          options, futures, and forward contracts (other than those on
          foreign currencies), and (iii) foreign currencies (including
          options, futures, and forward contracts on such currencies) not
          directly related to the Fund's principal business of investing in
          stock or securities (or options and futures with respect to
          stocks or securities)) held less than 3 months (the "30%
          Limitation"); (c) diversify its holdings so that, at the end of
          each quarter of the taxable year, (i) at least 50% of the market
          value of the Fund's assets is represented by cash and cash items
          (including receivables), U.S. Government securities, the
          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 not greater
          than 10% of the outstanding voting securities of such issuer, and
          (ii) not more than 25% of the value of its total assets is
          invested in the securities (other than U.S. Government securities
          or the securities of other regulated investment companies) of any
          one issuer, or of two or more issuers which a Fund controls and
          which are determined to be engaged in the same or similar trades
          or businesses or related trades or businesses; and (d) distribute
          at least 90% of its investment company taxable income (which



                                        - 38 -
<PAGE>   87





          includes, among other items, dividends, interest and net short-
          term capital gains in excess of net long-term capital losses) and
          its net tax-exempt interest income each taxable year.

               As a regulated investment company, each Fund generally will
          not be subject to U.S. federal income tax on its investment
          company taxable income and net capital gains (the excess of net
          long-term capital gains over net short-term capital losses), if
          any, that it distributes to Shareholders.  Each Fund intends to
          distribute to its Shareholders, at least annually, substantially
          all of its investment company taxable income and net capital
          gains.  Amounts, other than tax-exempt interest, not distributed
          on a timely basis in accordance with a calendar year distribution
          requirement are subject to a nondeductible 4% excise tax.  To
          prevent imposition of the excise tax, each Fund must distribute
          during each calendar year an amount equal to the sum of (1) at
          least 98% of its ordinary income (not taking into account any
          capital gains or losses) for the calendar year, (2) at least 98%
          of its capital gains in excess of its capital losses (adjusted
          for certain ordinary losses, as prescribed by the Code) for the
          one-year period ending on October 31 of the calendar year, and
          (3) any ordinary income and capital gains for previous years that
          were not distributed during those years.  A distribution,
          including an "exempt-interest dividend," will be treated as paid
          on December 31 of the current calendar year if it is declared by
          a Fund in October, November or December to shareholders of record
          on a date in such a month and paid by the Fund during January of
          the following calendar year.  Such distributions will be treated
          as received by Shareholders in the calendar year in which the
          distributions are declared, rather than the calendar year in
          which the distributions are received.  To prevent application of
          the excise tax, each Fund intends to make its distributions in
          accordance with the calendar year distribution requirement.

               DISTRIBUTIONS.  Dividends paid out of a Fund's investment
          company taxable income generally will be taxable to a U.S.
          Shareholder as ordinary income.  Because no portion of the income
          derived by the U.S. Government Fund, the Fixed Income Fund and
          the Tax-Free Fund is expected to consist of dividends paid by
          U.S. corporations, no portion of the dividends paid by those
          Funds is expected to be eligible for the corporate dividends-
          received deduction.  A portion of the income of the Equity Fund,
          Balanced Fund and Aggressive Growth Fund may, however, consist of
          dividends paid by U.S. corporations and, accordingly, a portion
          of the dividends paid by that Fund may be eligible for the
          corporate dividends-received deduction.  Distributions of net
          capital gains, if any, designated as capital gain dividends are
          taxable as long-term capital gains, regardless of how long the
          Shareholder has held the Fund's Shares, and are not eligible for
          the dividends-received deduction.  The U.S. Government Fund is



                                        - 39 -
<PAGE>   88





          not expected to realize any long-term capital gains or losses.
          Shareholders receiving distributions in the form of additional
          Shares, rather than cash, generally will have a cost basis in
          each such Share equal to the net asset value of a Share of the
          Fund on the reinvestment date.  Shareholders will be notified
          annually as to the U.S. federal tax status of distributions, and
          Shareholders receiving distributions in the form of additional
          Shares will receive a report as to the net asset value of those
          Shares.

               Distributions by a Fund reduce the net asset value of Fund
          shares.  Should a taxable distribution reduce the net asset value
          below a Shareholder's cost basis, the distribution nevertheless
          would be taxable to the Shareholder as ordinary income or capital
          gain as described above, even though, from an investment
          standpoint, it may constitute a partial return of capital.  In
          particular, investors should be careful to consider the tax
          implications of buying shares just prior to a distribution by a
          Fund.  The price of shares purchased at that time includes the
          amount of the forthcoming distribution, but the distribution will
          generally be taxable to them.

               DISCOUNT SECURITIES.  Investments by a Fund in securities
          that are issued at a discount will result in income to the Fund
          equal to a portion of the excess of the face value of the
          securities over their issue price (the "original issue discount")
          each year that the securities are held, even though the Fund
          receives no cash interest payments.  This income is included in
          determining the amount of income which the Fund must distribute
          to maintain its status as a regulated investment company and to
          avoid the payment of federal income tax and the 4% excise tax.

               Some of the debt securities may be purchased by a Fund at a
          discount which exceeds the original issue discount on such debt
          securities, if any.  This additional discount represents market
          discount for federal income tax purposes.  Generally, the gain
          realized on the disposition of any debt security acquired after
          April 30, 1993 or any taxable debt security acquired prior to May
          1, 1993 having market discount will be treated as ordinary income
          to the extent it does not exceed the accrued market discount on
          such debt security.

               OPTIONS AND HEDGING TRANSACTIONS.  The taxation of equity
          options and over-the-counter options on debt securities is
          governed by Code section 1234.  Pursuant to Code section 1234,
          the premium received by a Fund for selling a put or call option
          is not included in income at the time of receipt.  If the option
          expires, the premium is short-term capital gain to the Fund.  If
          the Fund enters into a closing transaction, the difference
          between the amount paid to close out its position and the premium



                                        - 40 -
<PAGE>   89





          received is short-term capital gain or loss.  If a call option
          written by a Fund is exercised, thereby requiring the Fund to
          sell the underlying security, the premium will increase the
          amount realized upon the sale of such security and any resulting
          gain or loss will be a capital gain or loss, and will be long-
          term or short-term depending upon the holding period of the
          security.  With respect to a put or call option that is purchased
          by a Fund, if the option is sold, any resulting gain or loss will
          be a capital gain or loss, and will be long-term or short-term,
          depending upon the holding period of the option.  If the option
          expires, the resulting loss is a capital loss and is long-term or
          short-term, depending upon the holding period of the option.  If
          the option is exercised, the cost of the option, in the case of a
          call option, is added to the basis of the purchased security and,
          in the case of a put option, reduces the amount realized on the
          underlying security in determining gain or loss.

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

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

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

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

               The 30% Limitation and the diversification requirements
          applicable to each Fund's assets may limit the extent to which
          each Fund will be able to engage in transactions in options.

               The Equity Fund may invest in shares of foreign corporations
          (through ADRs) which may be classified under the Code as passive
          foreign investment companies ("PFICs").  In general, a foreign
          corporation is classified as a PFIC if at least one-half of its
          assets constitute investment-type assets, or 75% or more of its
          gross income is investment-type income.  If the Fund receives a
          so-called "excess distribution" with respect to PFIC stock, the
          Fund itself may be subject to a tax on a portion of the excess
          distribution, whether or not the corresponding income is
          distributed by the Fund to Shareholders.  In general, under the
          PFIC rules, an excess distribution is treated as having been
          realized ratably over the period during which the Fund held the
          PFIC shares.  The Fund itself will be subject to tax on the
          portion, if any, of an excess distribution that is so allocated
          to prior Fund taxable years and an interest factor will be added
          to the tax, as if the tax had been payable in such prior taxable
          years.  Certain distributions from a PFIC as well as gain from
          the sale of PFIC shares are treated as excess distributions.
          Excess distributions are characterized as ordinary income even
          though, absent application of the PFIC rules, certain excess
          distributions might have been classified as capital gain.

               The Equity Fund may be eligible to elect alternative tax
          treatment with respect to PFIC shares.  Under an election that
          currently is available in some circumstances, the Fund generally
          would be required to include in its gross income its share of the
          earnings of a PFIC on a current basis, regardless of whether
          distributions are received from the PFIC in a given year.  If
          this election were made, the special rules, discussed above,
          relating to the taxation of excess distributions, would not
          apply.  In addition, another election may be available that would
          involve marking to market the Fund's PFIC shares at the end of
          each taxable year (and on certain other dates prescribed in the
          Code), with the result that unrealized gains are treated as
          though they were realized.  If this election were made, tax at
          the Fund level under the PFIC rules would generally be
          eliminated, but the Fund could, in limited circumstances, incur
          nondeductible interest charges.  The Fund's intention to qualify



                                        - 42 -
<PAGE>   91





          annually as a regulated investment company may limit its
          elections with respect to PFIC shares.

               Because the application of the PFIC rules may affect, among
          other things, the character of gains, the amount of gain or loss
          and the timing of the recognition of income with respect to PFIC
          shares, as well as subject the Fund itself to tax on certain
          income from PFIC shares, the amount that must be distributed to
          Shareholders, and which will be taxed to Shareholders as ordinary
          income or long-term capital gain, may be increased or decreased
          substantially as compared to a fund that did not invest in PFIC
          shares.

               SALE OF SHARES.  Upon the sale or other disposition of
          Shares of a Fund, or upon receipt of a distribution in complete
          liquidation of a Fund, a Shareholder generally will realize a
          taxable capital gain or loss which will be long-term or short-
          term, generally depending upon the Shareholder's holding period
          for the Shares.  Any loss realized on a sale or exchange will be
          disallowed to the extent the Shares disposed of are replaced
          (including Shares acquired pursuant to a dividend reinvestment
          plan) within a period of 61 days beginning 30 days before and
          ending 30 days after disposition of the Shares.  In such a case,
          the basis of the Shares acquired will be adjusted to reflect the
          disallowed loss.  Any loss realized by a Shareholder on a
          disposition of Fund Shares held by the Shareholder for six months
          or less will be treated as a long-term capital loss to the extent
          of any distributions of net capital gains received by the
          Shareholder with respect to such Shares.  Furthermore, a loss
          realized by a Shareholder on the redemption, sale or exchange of
          Shares of a Fund with respect to which exempt-interest dividends
          have been paid will, to the extent of such exempt-interest
          dividends, be disallowed if such Shares have been held by the
          Shareholder for less than six months.

               In some cases, Shareholders will not be permitted to take
          sales charges into account for purposes of determining the amount
          of gain or loss realized on the disposition of their Shares.
          This prohibition generally applies where (1) the Shareholder
          incurs a sales charge in acquiring the stock of a regulated
          investment company, (2) the stock is disposed of before the 91st
          day after the date on which it was acquired, and (3) the
          Shareholder subsequently acquires Shares of the same or another
          regulated investment company and the otherwise applicable sales
          charge is reduced or eliminated under a "reinvestment right"
          received upon the initial purchase of Shares of stock.  In that
          case, the gain or loss recognized will be determined by excluding
          from the tax basis of the Shares exchanged all or a portion of
          the sales charge incurred in acquiring those Shares.  This
          exclusion applies to the extent that the otherwise applicable



                                        - 43 -
<PAGE>   92





          sales charge with respect to the newly acquired Shares is reduced
          as a result of having incurred a sales charge initially.  Sales
          charges affected by this rule are treated as if they were
          incurred with respect to the stock acquired under the
          reinvestment right.  This provision may be applied to successive
          acquisitions of stock.

               FOREIGN WITHHOLDING TAXES.  Income received by a Fund from
          sources within foreign countries may be subject to withholding
          and other taxes imposed by such countries.

               BACKUP WITHHOLDING.  Each Fund may be required to withhold
          U.S. federal income tax at the rate of 31% of all reportable
          dividends (which does not include exempt-interest dividends) and
          capital gain distributions (as well as redemptions for all Funds
          except the U.S. Government Fund) payable to Shareholders who fail
          to provide the Fund with their correct taxpayer identification
          number or to make required certifications, or who have been
          notified by the IRS that they are subject to backup withholding.
          Corporate Shareholders and certain other Shareholders specified
          in the Code generally are exempt from such backup withholding.
          Backup withholding is not an additional tax.  Any amounts
          withheld may be credited against the Shareholder's U.S. federal
          income tax liability.

               FOREIGN SHAREHOLDERS.  The tax consequences to a foreign
          Shareholder of an investment in a Fund may be different from
          those described herein.  Foreign Shareholders are advised to
          consult their own tax advisers with respect to the particular tax
          consequences to them of an investment in a Fund.

               OTHER TAXATION.  The Group is organized as a Massachusetts
          business trust and, under current law, neither the Group nor any
          Fund is liable for any income or franchise tax in the
          Commonwealth of Massachusetts, provided that each Fund continues
          to qualify as a regulated investment company under Subchapter M
          of the Code.

               Fund Shareholders may be subject to state and local taxes on
          their Fund distributions.  In certain states, Fund distributions
          which are derived from interest on obligations of that state or
          any municipality or political subdivision thereof may be exempt
          from taxation.  Also, in many states, Fund distributions which
          are derived from interest on certain U.S. Government obligations
          may be exempt from taxation.

          Additional Tax Information Concerning the Tax-Free Fund
          -------------------------------------------------------

               The Tax-Free Fund intends to qualify under the Code to pay
          "exempt-interest dividends" to its Shareholders.  The Tax-Free



                                        - 44 -
<PAGE>   93





          Fund will be so qualified if, at the close of each quarter of its
          taxable year, at least 50% of the value of its total assets
          consists of securities on which the interest payments are exempt
          from the regular federal income tax.  To the extent that
          dividends distributed by the Tax-Free Fund to its Shareholders
          are derived from interest income exempt from federal income tax
          and are designated as "exempt-interest dividends" by the Fund,
          they will be excludable from the gross incomes of the
          Shareholders for regular federal income tax purposes.  "Exempt-
          interest dividends," however, must be taken into account by
          Shareholders in determining whether their total incomes are large
          enough to result in taxation of up to eighty-five percent of
          their social security benefits and certain railroad retirement
          benefits.  It should also be noted that tax-exempt interest on
          private activity bonds in which the Tax-Free Fund may invest
          generally is treated as a tax preference item for purposes of the
          alternative minimum tax for corporate and individual
          Shareholders.  Exempt interest dividends also may be part of an
          adjustment to alternative minimum taxable income of corporations
          and are included in the base of the environmental tax on
          corporations imposed under Code section 59A.  The Tax-Free Fund
          will inform Shareholders annually as to the portion of the
          distributions from the Fund which constituted "exempt-interest
          dividends."

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

               Under the Code, a Shareholder may not deduct that portion of
          interest on indebtedness incurred or continued to purchase or
          carry shares of an investment company paying exempt-interest
          dividends (such as those of the Tax-Free Fund) which bears the
          same ratio to the total of such interest as the exempt-interest
          dividends bear to the total dividends (excluding net capital gain
          dividends) received by the Shareholder.  In addition, under rules
          issued by the Internal Revenue Service for determining when
          borrowed funds are considered to be used to purchase or carry
          particular assets, the purchase of Shares may be considered to
          have been made with borrowed funds even though the borrowed funds
          are not directly traceable to such purchase.

               Shareholders are advised to consult their own tax advisers
          with respect to the particular tax consequences to them of an
          investment in a Fund.  Persons who may be "substantial users" (or
          "related persons" of substantial users) of facilities financed by
          industrial development bonds or private activity bonds should



                                        - 45 -
<PAGE>   94





          consult their tax advisers before purchasing shares of the Tax-
          Free Fund.  The term "substantial user" generally includes any
          "non-exempt person" who regularly uses in his or her trade or
          business a part of a facility financed by industrial development
          bonds or private activity bonds.  Generally, an individual will
          not be a "related person" of a substantial user under the Code
          unless the person or his or her immediate family owns directly or
          indirectly in the aggregate more than a 50% equity interest in
          the substantial user.

               The Tax-Free Fund may acquire rights regarding specified
          portfolio securities under puts.  See "Put Options."  The policy
          of the Tax-Free Fund is to limit its acquisition of puts to those
          under which the Fund will be treated for federal income tax
          purposes as the owner of the Municipal Securities acquired
          subject to the put and the interest on the Municipal Securities
          will be tax-exempt to the Fund.  Although the Internal Revenue
          Service has issued a published ruling that provides some guidance
          regarding the tax consequences of the purchase of puts, there is
          currently no guidance available from the Internal Revenue Service
          that definitively establishes the tax consequences of many of the
          types of puts that the Fund could acquire under the Investment
          Company Act of 1940.  Therefore, although the Tax-Free 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 from that of the Fund.

               The foregoing is only a summary of some of the important
          federal tax considerations generally affecting purchasers of
          Shares of the Tax-Free Fund.  Additional tax information
          concerning all of the Funds is contained in the immediately
          preceding section of this Statement of Additional Information.
          No attempt is made to present a detailed explanation of the
          income tax treatment of the Tax-Free Fund or its Shareholders,
          and this discussion is not intended as a substitute for careful
          tax planning.  Accordingly, potential purchasers of shares of the
          Tax-Free Fund are urged to consult their tax advisers with
          specific reference to their own tax situation.

          Yields and Total Returns of the U.S. Government Fund
          ----------------------------------------------------

               As summarized in the Prospectus of the U.S. Government Fund
          under the heading "Performance Information," the yield of the
          U.S. Government Fund for a seven-day period (the "base period")
          will be computed by determining the net change in value
          (calculated as set forth below) of a hypothetical account having
          a balance of one share at the beginning of the period, dividing
          the net change in account value by the value of the account at
          the beginning of the base period to obtain the base period
          return, and multiplying the base period return by 365/7 with the



                                        - 46 -
<PAGE>   95





          resulting yield figure carried to the nearest hundredth of one
          percent.  Net changes in value of a hypothetical account will
          include 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, but will not
          include realized gains or losses or unrealized appreciation or
          depreciation on portfolio investments.  Yield may also be
          calculated on a compound basis (the "effective yield") which
          assumes that net income is reinvested in Fund Shares at the same
          rate as net income is earned for the base period.

               The yield and effective yield of the U.S. Government Fund
          will vary in response to fluctuations in interest rates and in
          the expenses of the Fund.  For comparative purposes the current
          and effective yields should be compared to current and effective
          yields offered by competing financial institutions for the same
          base period and calculated by the methods described below.

               The current and effective seven-day average yields as of
          March 31, 1995 for the U.S. Government Fund were 5.53% and 5.68%,
          respectively.

               The U.S. Government Fund may wish to publish total return
          figures in its sales literature and other advertising materials.
          For a discussion of the manner in which such total return figures
          are calculated, see "Yields and Total Returns of the Variable NAV
          Funds--Total Return Calculations" below.

          Yields and Total Returns of the Variable NAV Funds
          --------------------------------------------------

               YIELD CALCULATIONS.  As summarized in the Prospectuses of
          the Funds under the heading "PERFORMANCE INFORMATION", yields of
          each of the Funds except the U.S. Government Fund will be
          computed by dividing the net investment income per share (as
          described below) earned by the Fund during a 30-day (or one
          month) period by the maximum offering price 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.  A 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:





                                        - 47 -
<PAGE>   96





                                       a - b
                         Yield = 2 [(------- + 1)6 - 1]
                                       cd

          Where:    a    =    dividends and interest earned during the
                              period.

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

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

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

               For the purpose of determining net investment income earned
          during the period (variable "a" in the formula), dividend income
          on equity securities held by a Fund is recognized by accruing
          1/360 of the stated dividend rate of the security each day that
          the security is in that Fund.  Interest earned on any debt
          obligations held by a Fund is calculated by computing the yield
          to maturity of each obligation held by that Fund based on the
          market value of the obligation (including actual accrued
          interest) at the close of business on the last Business Day of
          each month, or, with respect to obligations purchased during the
          month, 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 month that the
          obligation is held by that Fund.  For purposes of this
          calculation, it is assumed that each month contains 30 days.  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 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.

               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 base period, has not been declared as a dividend, but is
          reasonably expected to be and is declared as a dividend shortly
          thereafter.

               For the 30-day period ended March 31, 1995, the yield for
          the Fixed Income Fund, Tax-Free Fund and the Equity Fund was
          5.84%, 4.19% and 1.09%, respectively.
   
               For the 30-day period ended September 30, 1995, the yield
          for the Balanced Fund was 2.73% and the yield for the Fixed Total
          Return Fund was 5.42%.
    
               During any given 30-day period, AMCORE or the Administrator
          may voluntarily waive all or a portion of their fees with respect
          to a Fund.  Such waiver would cause the yield of that Fund to be
          higher than it would otherwise be in the absence of such a
          waiver.

               From time to time, the tax equivalent 30-day yield of the
          Tax-Free Fund may be presented in advertising and sales
          literature.  The tax equivalent 30-day yield will be computed by
          dividing that portion of the Fund's yield which is tax-exempt by
          one minus a stated tax rate and adding the product to that
          portion, if any, of the yield of the Fund that is not tax-exempt.

               TOTAL RETURN CALCULATIONS.  As summarized in the
          Prospectuses of the Funds under the heading "PERFORMANCE
          INFORMATION", average annual total return is a measure of the
          change in value of an investment in a Fund over the period
          covered, which assumes any dividends or capital gains
          distributions are reinvested in the Fund immediately rather than
          paid to the investor in cash.  The Funds compute their average
          annual total returns by determining the average annual compounded
          rates of return during specified periods that equate the initial
          amount invested to the ending redeemable value of such
          investment.  This is done 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:

               Average Annual         ERV
                 Total Return =    [(------)1/n - 1]
                                       P

          Where:    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.





                                        - 49 -
<PAGE>   98





                      n       =    period covered by the computation,
                                   expressed in terms of years.

               The Funds compute their aggregate total returns 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:

               Aggregate Total        ERV
                  Return      =    [(------] - 1]
                                       P

                    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.


               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.  The ending redeemable value (variable "ERV" in each
          formula) is determined by assuming complete redemption of the
          hypothetical investment and the deduction of all nonrecurring
          charges at the end of the period covered by the computations.
   
               In the case of the Fixed Income Fund, the Tax-Free Fund and
          the Equity Fund, based upon the period beginning with each such
          Fund's commencement of operations (December 21, 1992) through
          March 31, 1995, the average annual total return for each Fund,
          assuming the imposition of the maximum applicable sales charge,
          was as follows:  2.39% for the Fixed Income Fund, 1.84% for the
          Tax-Free Fund, and 5.44% for the Equity Fund.  Assuming that the
          maximum applicable sales charge had not been imposed, the average
          annual total return for this same period would have been as
          follows:  4.57% for the Fixed Income Fund, 4.24% for the Tax-Free
          Fund, and 7.92% for the Equity Fund.  The Funds no longer impose
          sales charges upon their purchase.

               In the case of the Balanced Fund, based upon the Fund's
          commencement of operations (June 1, 1995) through September 30,
          1995, the aggregate total return for the Fund was 6.26%.  In the
          case of the Fixed Total Return Fund, based upon the Fund's
          commencement of operations (June 15, 1995) through September 30,
          1995, the aggregate total return for the Fund was 1.59%.

          Performance Comparisons
          -----------------------

               Investors may judge the performance of the Funds by
          comparing them to the performance of other mutual funds or mutual
          fund portfolios with comparable investment objectives and
          policies through various mutual fund or market indices such as
          those prepared by Dow Jones & Co., Inc. and Standard & Poor's
          Corporation and to data prepared by Lipper Analytical Services,
          Inc., a widely recognized independent service which monitors the
          performance of mutual funds or Ibbotson Associates, Inc.
          Comparisons may also be made to indices or data published in
          IBC/Donaghue'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, and
          U.S.A. Today.  In addition to performance information, general
          information about the Funds that appears in a publication such as
          those mentioned above may be included in advertisements and in
          reports to Shareholders.  The Funds may also include in
          advertisements and reports to Shareholders information comparing
          the performance of AMCORE or its predecessors to other investment
          advisers; such comparisons may be published by or included in
          Nelsons Directory of Investment Managers, Roger's, Casey/PIPER
          Manager Database or CDA/Cadence.

               Current yields or performance will fluctuate from time to
          time and are not necessarily representative of future results.
          Accordingly, a Fund's yield or performance may not provide for
          comparison with bank deposits or other investments that pay a
          fixed return for a stated period of time.  Yield and performance
          are functions of a Fund's quality, composition and maturity, as
          well as expenses allocated to the Fund.  Fees imposed upon
          Customer accounts by the Adviser or its affiliated or
          correspondent banks for cash management services will reduce a
          Fund's effective yield to Customers.

               From time to time, the Fund may include general comparative
          information, such as statistical data regarding inflation,
          securities indices or the features or performance of alternative
          investments, in advertisements, sales literature and reports to
          shareholders.  The Funds may also include calculations, such as
          hypothetical compounding examples, which describe hypothetical
          investment results in such communications.  Such performance
          examples will be based on an express set of assumptions and are
          not indicative of the performance of any Fund.

          recent fiscal year or half-year and to provide the views of
          AMCORE and/or Group officers regarding expected trends and
          strategies.

               Individual Trustees are elected by the Shareholders and,
          subject to removal by the vote of two-thirds of the Board of
          Trustees, serve for a term lasting until the next meeting of
          Shareholders at which Trustees are elected.  Such meetings are
          not required to be held at any specific intervals.  Shareholders
          owning not less than 10% of the outstanding Shares of the Group
          entitled to vote may cause the Trustees to call a special
          meeting, including for the purpose of considering the removal of
          one or more Trustees.  Any Trustee may be removed at any meeting
          of Shareholders by vote of two-thirds of the Group's outstanding
          shares.  The Declaration of Trust provides that the Trustees will
          assist shareholder communications to the extent required by
          Section 16(c) of the 1940 Act in the event that a shareholder
          request to hold a special meeting is made.

               The nationally recognized statistical rating organizations
          (individually, an "NRSRO") that may be utilized by the Adviser
          with regard to portfolio investments for the Funds include
          Moody's Investors Service, Inc. ("Moody's") and Standard & Poor's
          Corporation ("S&P") and Duff & Phelps, Inc. ("D&F").  Set forth
          below is a description of the relevant ratings of each such
          NRSRO.  The NRSROs that may be utilized by the Adviser and the
          description of each NRSRO's ratings is as of the date of this
          Statement of Additional Information, and may subsequently change.

          LONG TERM DEBT RATINGS (may be assigned, for example, to
          corporate and municipal bonds)

          Description of the three highest long-term debt ratings by
          Moody's (Moody's applies numerical modifiers (1, 2, and 3) in
          each rating category to indicate the security's ranking within
          the category):

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

               A    Bonds which are rated A 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 some time in the future.

          Description of the three highest long-term debt ratings by S&P
          (S&P may apply a plus (+) or minus (-) to a particular rating
          classification to show relative standing within that
          classification):
<PAGE>   103





               AAA  Debt rated AAA has the highest rating assigned by S&P.
                    Capacity to pay interest and repay principal is
                    extremely strong.

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

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

          Description of the three highest long-term debt ratings by D&P;

               AAA  Highest credit quality.  The risk factors are
                    negligible being only slightly more than for risk-free
                    U.S. Treasury debt.

               AA+  High credit quality Protection factors are strong.
               AA   Risk is modest but may vary slightly from time to time
               AA-  because of economic conditions.

               A+   Protection factors are average but adequate.  However,
               A    risk factors are more variable and greater in periods
          of
               A-   economic stress.

          SHORT-TERM DEBT RATINGS (may be assigned, for example, to
          commercial paper, master demand notes, bank instruments, and
          letters of credit)

          Moody's description of its three highest short-term debt ratings:

               Prime-1   Issuers rated Prime-1 (or supporting institutions)
                         have a superior capacity for repayment of senior
                         short-term promissory obligations.  Prime-1
                         repayment capacity will normally be evidenced by
                         many of the following characteristics:

                         -    Leading market positions in well-established
                              industries.

                         -    High rates of return on Funds employed.

                         -    Conservative capitalization structures with
                              moderate reliance on debt and ample asset
                              protection.




                                         A-2
<PAGE>   104





                         -    Broad margins in earnings coverage of fixed
                              financial charges and high internal cash
                              generation.

                         -    Well-established access to a range of
                              financial markets and assured sources of
                              alternate liquidity.

               Prime-2   Issuers rated Prime-2 (or supporting institutions)
                         have a strong capacity 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, 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 rated Prime-3 (or supporting institutions)
                         have an acceptable ability for repayments of
                         senior short-term obligations.  The effect 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.

          S&P's description of its three highest short-term debt ratings:

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

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

               A-3  Issues carrying this designation have adequate capacity
                    for timely payment.  They are, however, more vulnerable
                    to the adverse effects of changes in circumstances than
                    obligations carrying the higher designations.

               D&P's description of the short-term debt ratings (D&P
          incorporates gradations of "1+" (one plus) and "1-" (one minus)
          to assist investors in recognizing quality differences within the
          highest rating category);



                                         A-3
<PAGE>   105





               Duff 1+   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.

               Duff 1    Very high certainty of timely payment.  Liquidity
                         factors are excellent and supported by good
                         fundamental protection factors.  Risk factors are
                         minor.

               Duff 1-   High certainty of timely payment.  Liquidity
                         factors are strong and supported by good
                         fundamental protection factors.  Risk factors are
                         very small.

               Duff 2    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.

          Short-Term Loan/Municipal Note Ratings
          --------------------------------------

          Moody's description of its two highest short-term loan/municipal
          note ratings:

          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.  Margins of
                         protection are ample although not so large as in
                         the preceding group.

          S&P's description of its two highest municipal note ratings:

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

               SP-2 Satisfactory capacity to pay principal and interest.

          Definitions of Certain Money Market Instruments
          -----------------------------------------------

          Commercial Paper





                                         A-4
<PAGE>   106





               Commercial paper consists of unsecured promissory notes
          issued by corporations.  Issues of commercial paper normally have
          maturities of less than nine months and fixed rates of return.

          Certificates of Deposit

               Certificates of Deposit are negotiable certificates issued
          against funds deposited in a commercial bank or a savings and
          loan association for a definite period of time and earning a
          specified return.

          Bankers' Acceptances

               Bankers' acceptances are negotiable drafts or bills of
          exchange, normally drawn by an importer or exporter to pay for
          specific merchandise, which are "accepted" by a bank, meaning, in
          effect, that the bank unconditionally agrees to pay the face
          value of the instrument on maturity.

          U.S. Treasury Obligations

               U.S. Treasury Obligations are obligations issued or guaran-
          teed as to payment of principal and interest by the full faith
          and credit of the U.S. Government.  These obligations may include
          Treasury bills, notes and bonds, and issues of agencies and
          instrumentalities of the U.S. Government, provided such obliga-
          tions are guaranteed as to payment of principal and interest by
          the full faith and credit of the U.S. Government.

          U.S. Government Agency and Instrumentality Obligations

               Obligations of the U.S. Government include Treasury bills,
          certificates of indebtedness, notes and bonds, and issues of
          agencies and instrumentalities of the U.S. Government, such as
          the Government National Mortgage Association, the Export-Import
          Bank of the United States, the Tennessee Valley Authority, the
          Farmers Home Administration, the Federal Home Loan Banks, the
          Federal Intermediate Credit Banks, the Federal Farm Credit Banks,
          the Federal Land Banks, the Federal Housing Administration, the
          Federal National Mortgage Association, the Federal Home Loan
          Mortgage Corporation, and the Student Loan Marketing Association.
          Some of these obligations, such as those of the Government
          National Mortgage Association and the Export-Import Bank of the
          United States, are supported by the full faith and credit of the
          U.S. Treasury; others, such as those of the Federal National
          Mortgage Association are supported by the right of the issuer to
          borrow from the Treasury; others, such as those of the Student
          Loan Marketing Association, are supported by the discretionary
          authority of the U.S. Government to purchase the agency's
          obligations; still others, such as those of the Federal Farm

          Credit Banks, 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.

                               SEPTEMBER 30, 1995
                                  (UNAUDITED)

1.   ORGANIZATION:

         The Coventry Group ("Group") was organized on January 8, 1992 as a
         Massachusetts business trust, and is registered under the Investment
         Company Act of 1940, as amended ("the 1940 Act"), as a diversified,
         open-end management investment company.  Between the date of
         organization and the date of commencement of operations of the AMCORE
         Vintage Balanced Fund and the AMCORE Vintage Fixed Total Return Fund,
         (individually, a "Fund"; collectively, the "Funds"), each a series of
         the Group, the Funds earned no investment income and had no operations
         other than incurring organizational expenses.  The Aggressive Growth
         Fund, which commenced operations October 3, 1995, is not presented in
         these financial statements.

         The Group is authorized to issue an unlimited number of shares which
         are units of beneficial interest with a par value of $0.01 per share.
         Sales of shares of the Funds may be made to the general public.

2.   SIGNIFICANT ACCOUNTING PRINCIPLES:

         The following is a summary of significant accounting policies followed
         by the Funds in the preparation of their financial statements.  The
         policies are in conformity with generally accepted accounting
         principles.

         SECURITIES VALUATION:

         Investments in common and preferred stocks, commercial paper,
         corporate bonds, municipal bonds, U.S. Government securities and U.S.
         Government agency securities of the Funds are valued at their market
         values determined on the basis of the latest available bid quotation
         in the principal market (closing sales prices if the principal market
         is an exchange) in which such securities are normally traded.
         Investments in investment companies are valued at their respective net
         asset values as reported by such companies. Securities, including
         restricted securities, for which market quotations are not readily
         available, are valued at fair market value by the investment adviser
         under the supervision of the Group's Board of Trustees.  The
         differences between the cost and market values of investments held by
         the Funds are reflected as either unrealized appreciation or
         depreciation.

         SECURITY TRANSACTIONS AND RELATED INCOME:

         Security transactions are accounted for on the date the security is
         purchased or sold (trade date).  Interest income is recognized on the
         accrual basis and includes, where applicable, the prorata amortization
         of premium or discount.  Dividend income is recorded on the
         ex-dividend date.  Gains or losses realized on sales of securities are
         determined by comparing the identified cost of the security lot sold
         with the net sales proceeds.

         REPURCHASE AGREEMENTS:

         The Funds may acquire repurchase agreements from member banks of the
         Federal Deposit Insurance Corporation and from financial institutions
         such as banks and broker dealers which the investment adviser, AMCORE
         Capital Management, Inc. ("AMCORE"), 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, is required to maintain the value of collateral
         held pursuant to the agreement at not less than the repurchase price
         (including accrued interest). Securities subject to repurchase
         agreements are held by the Fund'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.

         DIVIDENDS TO SHAREHOLDERS:

         Dividends from net investment income are declared and paid quarterly
         for the Funds.  Distributable net realized capital gains, if any, are
         declared and distributed at least annually for each Fund.  These
         dividends are determined in accordance with income tax regulations
         which may differ from generally accepted accounting principles.  These
         differences are primarily due to deferrals of certain losses.

         FEDERAL INCOME TAXES:

         It is the policy of each Fund to continue to qualify as a regulated
         investment company by complying with the provisions available to

                                  (UNAUDITED)


The Winsbury Company Limited Partnership d/b/a The Winsbury Company
("Winsbury") is an Ohio limited partnership.  The sole general partner of
Winsbury is BISYS Fund Services, Inc.  The sole limited partner of Winsbury is
WC Subsidiary Corporation.  BISYS Fund Services, Inc., BISYS Fund Services
Ohio, Inc., and WC Subsidiary Corporation are all subsidiaries of The BISYS
Group, Inc.  On October 10, 1995, Winsbury changed its name to BISYS Fund
Services Limited Partnership d/b/a BISYS Fund Services.

Winsbury, with whom certain officers and trustees of the Group are affiliated,
serves the Funds as administrator.  Such officers and trustees are paid no fees
directly by the Funds for serving as officers and trustees of the Group.  Under
the terms of the administration agreement, Winsbury's fees are computed daily
as a percentage of the average net assets of each Fund.

BISYS Fund Services Ohio, Inc., (the "Company") serves the Funds as Transfer
Agent and Fund Accountant. Under the terms of the Transfer Agent and Fund
Accountant Agreements, the Company's fees are computed on the basis of number
of shareholders and average net assets, respectively.

The Group has adopted a Distribution and Shareholder Service Plan in accordance
with Rule 12b-1 under the 1940 Act, pursuant to which the Funds are authorized
to pay or reimburse Winsbury, as distributor, a periodic amount, calculated at
an annual rate not to exceed 0.25% of the average daily net asset value of each
of the Funds.  These fees are used by Winsbury to pay banks, including
affiliates of AMCORE, broker dealers and other institutions, or to reimburse
Winsbury or its affiliates, for administration, distribution and shareholder
services in connection with the distribution of Fund shares.  No amounts were
paid under the terms of this plan during the period ended September 30, 1995.

AMCORE has agreed that if the aggregate expenses of any of the Funds, as
defined, for any fiscal year exceed the expense limitation of any State having
jurisdiction over the Fund, AMCORE will reimburse to the Fund, or otherwise
bear, such excess.  Such limitation did not affect the calculation of the
investment advisory fees during the six months ended September 30, 1995.
Further, fees may be voluntarily reduced to assist the Funds in maintaining
competitive expense ratios.

Information regarding these transactions is as follows for the period ended
September 30, 1995:

Item 27.  Indemnification
- -------   ---------------

          Article IV of the Registrant's Declaration of Trust states as follows:
 
     Section 4.3.  Mandatory Indemnification.
     -----------   -------------------------

     (a)  Subject to the exceptions and limitations contained in paragraph (b)
     below:

          (i)  every person who is, or has been, a Trustee or officer of the
          Trust shall be indemnified by the Trust to the fullest extent
          permitted by law against all liability and against all expenses
          reasonably incurred or paid by him in connection with any claim,
          action, suit or proceeding in which he becomes involved as a party or
          otherwise by virtue of his being or having been a Trustee or officer
          and against amounts paid or incurred by him in the settlement
          thereof; and
        
          (ii)  the words "claim," "action," "suit," or "proceeding" shall
          apply to all claims, actions, suits or proceedings (civil, criminal,
          administrative or other, including appeals), actual or threatened;
          and the words "liability" and "expenses" shall include, without
          limitation, attorneys fees, costs, judgments, amounts paid in
          settlement, fines, penalties and other liabilities.
        
     (b)  No indemnification shall be provided hereunder to a Trustee or 
     officer:





                                      C-6
<PAGE>   126
          (i)  against any liability to the Trust, a Series thereof, or the
          Shareholders by reason of a final adjudication by a court or other
          body before which a proceeding was brought that he engaged in willful
          misfeasance, bad faith, gross negligence or reckless disregard of the
          duties involved in the conduct of his office;
        
          (ii)  with respect to any matter as to which he shall have been
          finally adjudicated not to have acted in good faith in the reasonable
          belief that his action was in the best interest of the Trust; or
        
          (iii)  in the event of a settlement or other disposition not
          involving a final adjudication as provided in paragraph (b)(i) or
          (b)(ii) resulting in a payment by a Trustee or officer, unless there
          has been a determination that such Trustee or officer did not engage
          in willful misfeasance, bad faith, gross negligence or reckless
          disregard of the duties involved in the conduct of his office:
        
               (A)  by the court or other body approving the settlement or other
               disposition; or

               (B)  based upon a review of readily available facts (as opposed
               to a full trial-type inquiry) by (1) vote of a majority of the
               Disinterested Trustees acting on the matter (provided that a
               majority of the Disinterested Trustees then in office acts on
               the matter) or (2) written opinion of independent legal counsel.
        
     (c)  The rights of indemnification herein provided may be insured against
     by policies maintained by the Trust, shall be severable, shall not affect
     any other rights to which any Trustee or officer may now or hereafter be
     entitled, shall continue as to a person who has ceased to be such Trustee
     or officer and shall inure to the benefit of the heirs, executors,
     administrators and assigns of such person.  Nothing contained herein shall
     affect any rights to indemnification to which personnel of the Trust other
     than Trustees and  officers may be entitled by contract or otherwise under
     law.      
        
     (d)  Expenses of preparation and presentation of a defense to any claim,
     action, suit or proceeding of the character described in paragraph (a) of
     this Section 4.3 may be advanced by the Trust prior to final disposition   
     thereof upon receipt of an undertaking by or on behalf of the
        




                                      C-7
<PAGE>   127
     recipient to repay such amount if it is ultimately determined that he is
     not entitled to indemnification under this Section 4.3, provided that
     either:
        
          (i)  such undertaking is secured by a surety bond or some other
          appropriate security provided by the recipient, or the Trust shall be
          insured against losses arising out of any such advances; or         
        
          (ii)  a majority of the Disinterested Trustees acting on the matter
          (provided that a majority of the Disinterested Trustees acts on the
          matter) or an independent legal counsel in a written opinion shall
          determine, based upon a review of readily available facts (as opposed
          to a full trial-type inquiry), that there is reason to believe that
          the recipient ultimately will be found entitled to indemnification.
        
     As used in this Section 4.3, a "Disinterested Trustee" is one who is not
     (i) an Interested Person of the Trust (including anyone who has been
     exempted from being an Interested Person by any rule, regulation or order
     of the Commission), or (ii) involved in the claim, action, suit or
     proceeding.
        
          Insofar as indemnification for liabilities arising under the
          Securities Act of 1933 may be permitted to trustees, officers and
          controlling persons of the Registrant by the Registrant pursuant to
          the Declaration of Trust or otherwise, the Registrant is aware that
          in the opinion of the Securities and Exchange Commission, such
          indemnification is against public policy as expressed in the Act and,
          therefore, is unenforceable.  In the event that a claim for
          indemnification against such liabilities (other than the payment by
          the Registrant of expenses incurred or paid by trustees, officers or
          controlling persons of the Registrant in connection with the
          successful defense of any act, suit or proceeding) is asserted by
          such trustees, officers or controlling persons in connection with the
          shares being registered, the 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 
          issues.
