                CARDINAL GOVERNMENT SECURITIES MONEY MARKET FUND
                     CARDINAL TAX EXEMPT MONEY MARKET FUND
 
Cardinal Government Securities Money Market Fund (the "Government Securities
Fund") and Cardinal Tax Exempt Money Market Fund (the "Tax Exempt Fund")
(together called the "Funds" or individually a "Fund") are two separate
diversified investment funds of The Cardinal Group (the "Group"), an open-end,
management investment company. The Trustees of the Group have divided each
Fund's beneficial ownership into an unlimited number of transferable units
called shares (the "Shares").
 
The Government Securities Fund's investment objectives are maximizing current
income while preserving capital and maintaining liquidity. The Government
Securities Fund seeks to attain its objectives by investing as fully as
possible, but in no event less than 80% of its total assets, in U.S. Treasury
bills, notes and bonds, other obligations issued or guaranteed by the United
States, its agencies or instrumentalities, and repurchase agreements relating to
such obligations.
 
The Tax Exempt Fund's investment objectives are maximizing current income exempt
from federal income tax while preserving capital and maintaining liquidity. The
Tax Exempt Fund seeks to attain its objectives through professional management
of a high-grade portfolio of short-term municipal bonds and notes, tax-exempt
commercial paper and tax-exempt short-term discount notes.
 
   
All obligations purchased by each of the Funds will mature, or be deemed to
mature, in 397 calendar days or less. There can be no assurance that any Fund's
investment objectives will be achieved.
    
 
THE SHARES OF THE FUNDS ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR
ENDORSED BY ANY BANK, NOR ARE SUCH SHARES FEDERALLY INSURED OR GUARANTEED BY THE
UNITED STATES GOVERNMENT, THE FEDERAL DEPOSIT INSURANCE CORPORATION, THE FEDERAL
RESERVE BOARD OR ANY OTHER GOVERNMENTAL AGENCY. AN INVESTMENT IN A FUND INVOLVES
CERTAIN INVESTMENT RISKS, INCLUDING THE POSSIBLE LOSS OF PRINCIPAL. EACH FUND
INTENDS TO MAINTAIN A CONSTANT NET ASSET VALUE OF $1.00 PER SHARE, BUT THERE CAN
BE NO ASSURANCE THAT NET ASSET VALUE WILL NOT VARY.

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
From time to time each of the Funds may advertise its "yield" or "annualized
yield" and its "effective yield". In addition, the Tax Exempt Fund may advertise
its "tax equivalent yield" and its "tax equivalent effective yield." ALL YIELD
FIGURES ARE BASED ON HISTORICAL EARNINGS AND ARE NOT INTENDED TO INDICATE FUTURE
PERFORMANCE. The "yield" or "annualized yield" of a Fund refers to the income
generated by an investment in the Fund 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 a 52-week 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 Fund is assumed to be reinvested. The
"effective yield" will be slightly higher than the "yield" or "annualized yield"
because of the compounding effect of this assumed reinvestment. The "tax-
 
                                                                               5
<PAGE>   9
 
equivalent yield" demonstrates the taxable yield necessary to produce an
after-tax yield equivalent to that of the Tax Exempt Fund. The "tax-equivalent
effective yield" is calculated similarly to the "tax-equivalent yield" but, when
annualized, the income earned by an investment in the Tax Exempt Fund is assumed
to be reinvested. The "tax-equivalent effective yield" will be slightly higher
than the "tax-equivalent yield" because of the compounding effect of this
assumed reinvestment.
 
Investors may also judge the performance of a Fund by comparing or referencing
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 such as those prepared by Dow Jones & Co., Inc.,
Morningstar, Inc. and Standard & Poor's Corporation and to data prepared by
Lipper Analytical Services, Inc. Comparisons may also be made to indices or data
published in Donoghue's MONEY FUND REPORT of Holliston, Massachusetts, a
nationally recognized money market fund reporting service, Money Magazine,
Forbes, Barron's, The Wall Street Journal, The New York Times, The Columbus
Dispatch, Business Week, Consumer Reports 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

WHAT ARE THE FUNDS?
- --------------------------------------------------------------------------------
 
Each Fund is one separate diversified investment fund of the Group, which was
organized on March 23, 1993, as an Ohio business trust. The Group is registered
and operates as an open-end management investment company as defined in the
Investment Company Act of 1940, as amended (the "1940 Act"). The Government
Securities Fund and the Tax Exempt Fund were organized for the purposes of
acquiring all of the assets and liabilities of CGST and CTEMT, respectively, to
effect a reorganization of CGST and CTEMT from separate stand alone investment
companies to separate series of the Group (the "Reorganization").
 
- --------------------------------------------------------------------------------
WHAT ARE THE INVESTMENT OBJECTIVES AND POLICIES OF THE FUNDS?
- --------------------------------------------------------------------------------
 
IN GENERAL
 
The investment objectives of the Government Securities Fund are to maximize
current income while preserving capital and maintaining liquidity. The
investment objectives of the Tax Exempt Fund are to maximize current income
exempt from federal income tax while preserving capital and maintaining
liquidity. The investment objectives with respect to each Fund are fundamental
policies and as such may not be changed without a vote of the holders of a
majority of the outstanding Shares of that Fund (as defined below under "WHAT
ARE MY RIGHTS AS A SHAREHOLDER?"). There can be no assurance that the objectives
of any Fund will be achieved.
 
Each of the Funds, as a money market funds subject to Rule 2a-7 of the 1940 Act,
must invest exclusively in United States dollar-denominated instruments which
the Trustees of the Group and the Adviser determine present minimal credit risks
and which at the time of acquisition are rated by one or more appropriate
nationally recognized statistical rating organizations ("NRSROs") (e.g. Standard
& Poor's Corporation and Moody's Investors Service, Inc.) in one of the two
highest rating categories for short-term debt obligations or, if unrated, are of
comparable quality. In addition, the dollar-weighted average maturity of the
obligations in a Fund may not exceed 90 days.
 
THE GOVERNMENT SECURITIES FUND
 
The Government Securities Fund seeks to attain its investment objectives by
investing as fully as possible, but in no event less than 80% of its total
assets, in U.S. Treasury bills, notes and bonds, other obligations issued or
guaranteed by the United States, its agencies or instrumentalities and
repurchase agreements relating to such obligations. The Government Securities
Fund will purchase only obligations which have, or
 
6
<PAGE>   10
 
   
are deemed to have, maturities, from the date of purchase, of 397 calendar days
or less. Current income earned on such securities may not be as great as current
income that could be earned on lower quality securities that have less liquidity
and/or a greater risk of non-payment or securities that have a longer term.
    
 
Subject to the foregoing limitations and in order to achieve its investment
objectives, the Government Securities Fund expects to invest in the following
types of securities.
 
   
Direct obligations issued by the U.S. Treasury include bills, notes and bonds
which differ from each other only in interest rates, maturities and times of
issuance: Treasury bills have original maturities of one year or less; Treasury
notes have original maturities of one to ten years and Treasury bonds generally
have original maturities of greater than ten years.
    
 
Examples of obligations issued by agencies or instrumentalities of the U.S.
Government include, among others, securities issued by the General Services
Administration, Federal Housing Administration, Farmers Home Administration,
Government National Mortgage Association, Federal Home Loan Banks, Federal
Intermediate Credit Banks, Federal Land Banks, Federal Home Loan Mortgage
Corporation, Central Bank for Cooperatives, Maritime Administration, The
Tennessee Valley Authority, Washington, D.C. Armory Board, Export-Import Bank of
the United States, the International Bank for Reconstruction and Development,
Federal National Mortgage Association and Student Loan Marketing Association.
 
   
Certain of such U.S. Government obligations may have variable or floating rates
of interest. The Government Securities Fund intends to invest in variable and
floating rate instruments whose market value, upon reset of the interest rate,
will approximate amortized cost because their interest rates will be tied to
short-term market rates. Some obligations issued or guaranteed by U.S.
Government agencies or instrumentalities are supported by the full faith and
credit of the U.S. Treasury; others by U.S. Treasury guarantees; and others,
such as those issued by Federal Home Loan Banks, by the right of the issuer to
borrow from the Treasury. In addition, some obligations of U.S. Government
agencies or instrumentalities, such as those issued by the Federal National
Mortgage Association, are supported by the discretionary authority of the U.S.
Government to purchase certain obligations of the agency or instrumentality, and
others, such as those issued by the Student Loan Marketing Association, are
supported solely by the credit of the issuing agency or instrumentality itself.
No assurance can be given that the U.S. Government will provide financial
support to such U.S. Government sponsored agencies or instrumentalities in the
future, since it is not obligated to do so by law. The Government Securities
Fund will invest in such securities only when it is satisfied that the credit
risk with respect to the issuer is minimal.
    
 
THE TAX EXEMPT FUND
 
   
As a matter of policy, under normal market conditions, the Tax Exempt Fund will
invest at least 80% of its net assets in a diversified portfolio of Municipal
Securities (as defined below), the interest on which is both exempt from federal
income tax and not treated as a preference item for purposes of the federal
alternative minimum tax. Subject to the foregoing limitations and in order to
achieve its investment objectives, the Tax Exempt Fund expects to invest in the
following types of securities (collectively, "Municipal Securities"): bond
anticipation notes, construction loan notes, project notes, revenue anticipation
notes and tax anticipation notes which, in each case (1) are backed by the full
faith and credit of the United States, (2) are rated in one of the two highest
rating categories by an appropriate NRSRO for short-term tax-exempt securities
(e.g., MIG-1 or MIG-2, by Moody's Investors Service, Inc.) or (3) if the notes
are not rated, are, as determined by the Adviser in accordance with guidelines
established by the Group's Board of Trustees, of a quality equivalent to
securities so rated. The Tax Exempt Fund may also invest in municipal bonds and
participation interests therein, including industrial development revenue bonds
and pollution control revenue bonds, which have, or are deemed to have,
remaining maturities of 397 calendar days or less and (1) are rated in one of
the two highest rating categories by an appropriate NRSRO for short-term tax-
exempt securities, or (2) if not rated, are, as determined by the Adviser in
accordance with guidelines established by the Group's Board of Trustees, of a
quality equivalent to securities so rated. In addition, the Tax Exempt Fund may
purchase other types of tax-exempt Municipal Securities such as short-term
discount
    
 
                                                                               7
<PAGE>   11
 
notes. These investments must (1) be rated in one of the two highest rating
categories by an appropriate NRSRO for short-term tax exempt securities, or (2)
if not rated, possess equivalent characteristics and quality to securities so
rated in the opinion of the Adviser as determined in accordance with guidelines
established by the Board of Trustees. For further information regarding the
rating categories of the NRSROs, please see the Appendix to the Funds' Statement
of Additional Information.
 
Current income earned on such Municipal Securities may not be as great as
current income that could be earned on lower quality securities that have less
liquidity and/or a greater risk of nonpayment or securities that have a longer
term.
 
RISK FACTORS AND INVESTMENT TECHNIQUES
 
   
VARIABLE RATE SECURITIES. The Tax Exempt Fund has and intends to continue to
invest more than 25% of its assets in certain variable or floating rate demand
Municipal Securities, including participation interests therein. The value of
such securities may change with changes in interest rates generally. However,
the variable or floating rate nature of such securities should reduce, to the
extent the Tax Exempt Fund is invested in such securities, the degree of
fluctuation in the value of portfolio investments. Accordingly, as interest
rates decrease or increase, the potential for capital appreciation and the risk
of potential capital depreciation is less than would be the case with a
portfolio composed entirely of fixed income securities. The Tax Exempt Fund's
portfolio may contain variable or floating rate demand securities on which
stated minimum or maximum rates set by state law limit the degree to which
interest on such securities may fluctuate; to the extent it does, increases or
decreases in value may be somewhat greater than would be the case without such
limits. Because the adjustment of interest rates on the variable or floating
rate demand securities is made in relation to movements of the applicable
indexes (e.g., the prime rate), such securities are not comparable to
longer-term fixed rate securities. Accordingly, interest rates on such
securities may be higher or lower than current market rates for fixed rate
obligations of comparable quality with similar maturities. The Tax Exempt Fund,
however, will only acquire variable or floating rate securities the interest
rates on which are determined by reference to other short-term market rates of
interest. The Tax Exempt Fund will attempt to achieve a balance of variable or
floating and fixed rate securities such that under normal circumstances the net
asset value of the Tax Exempt Fund can be maintained at $1.00 per share while
the highest possible yield can be returned to investors. To the extent the Tax
Exempt Fund's portfolio is invested in variable or floating rate securities,
yield can be expected to decline in periods of falling interest rates more
rapidly than if the Tax Exempt Fund's portfolio is invested solely in
longer-term fixed rate securities. Conversely, yield, under the same
circumstances, can be expected to increase more rapidly in periods of rising
interest rates. Such instruments may be considered to be derivatives. A
derivative is generally defined as an instrument whose value is based upon, or
derived from, some underlying index, reference rate (e.g., interest rates),
security, commodity or other asset. As stated above, the Tax Exempt Fund has no
limit as to the percentage of its total assets that may be invested in such
variable or floating rate securities.
    
 
Variable rate demand Municipal Securities in which the Tax Exempt Fund invests
may be supported by bank letters of credit or comparable guarantees of financial
institutions. To the extent that 25% or more of the Tax Exempt Fund's assets are
invested in variable rate demand Municipal Securities supported by such letters
of credit or guarantees, the Tax Exempt Fund may be deemed to be concentrated in
the banking industry. (See "Certain Factors" below.)
 
REPURCHASE AGREEMENTS. Securities held by each of the Funds may be subject to
repurchase agreements. Under the terms of a repurchase agreement, a Fund would
acquire securities from a financial institution such as a well-established
securities dealer or a bank which is a member of the Federal Reserve System
which the Adviser deems creditworthy under guidelines approved by the Group's
Board of Trustees. At the time of purchase, the bank or securities dealer agrees
to repurchase the underlying securities from the Fund at a specified time and
price. The resale price reflects the purchase price plus an agreed upon market
rate of interest which is unrelated to the coupon rate or maturity of the
underlying security. The Funds will only enter into a repurchase agreement where
(i) the underlying securities are of the type which that Fund's
 
8
<PAGE>   12
 
investment policies would allow it to purchase directly, (ii) the market value
of the underlying security, including interest accrued, will at all times be
equal to or exceed the value of the repurchase agreement, and (iii) payment for
the underlying securities is made only upon physical delivery or evidence of
book-entry transfer to the account of the Funds' custodian or a bank acting as
agent. The Adviser will be responsible for continuously monitoring such
requirements. Use of repurchase agreements may cause the Tax Exempt Fund to earn
income which would be taxable to its shareholders.
 
INVESTMENT COMPANY SECURITIES. Each Fund may also invest up to 10% of the value
of its total assets in the securities of other investment companies subject to
the limitations set forth in the 1940 Act. The Funds intend to invest in the
securities of other money market mutual funds for purposes of short-term cash
management. A Fund's investment in such other investment companies may result in
the duplication of fees and expenses, particularly investment advisory fees. For
a further discussion of the limitations on the Funds' investments in other
investment companies, see "INVESTMENT OBJECTIVES AND POLICIES -- Additional
Information on Portfolio Instruments -- Securities of Other Investment
Companies" in the Funds' Statement of Additional Information.
 
WHEN-ISSUED AND DELAYED-DELIVERY TRANSACTIONS. Each Fund may also 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, although such transactions represent a form of
leveraging. 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 not pay for such
securities or start earning interest on them until they are received, although
the payment obligation and the coupon rate have been established before the time
the Fund enters into the commitment. When a Fund agrees to purchase such
securities, its 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 the Fund to miss a price or
yield considered to be advantageous.
 
Each Fund's commitments to purchase when-issued securities will not exceed 25%
of the value of its total assets absent unusual market conditions. In the event
that its commitments to purchase when-issued securities ever exceed 25% of the
value of its assets, such Fund's liquidity and the ability of the Adviser to
manage it might be adversely affected.
 
TAXABLE MONEY MARKET SECURITIES. Under normal market conditions, the assets of
the Tax Exempt Fund will be managed with a view towards producing only income
that is exempt from federal income taxation. However, the Tax Exempt Fund may
invest up to 20% of its assets in "temporary investments," that is, money market
instruments consisting of marketable obligations issued or guaranteed by the
U.S. Government, its agencies or instrumentalities, deposit obligations of banks
and savings and loans which are members of the Federal Deposit Insurance
Corporation, bankers' acceptances, high-grade commercial paper guaranteed or
issued by domestic corporations and repurchase agreements secured by such
obligations.
 
   
CERTAIN FACTORS. Naturally, there can be no assurance that any Fund will achieve
its investment objectives or be able continuously to maintain a net asset value
per share of $1.00. Specifically, with respect to the Tax Exempt Fund, the
characteristics of short-term Municipal Securities are such that the price
stability and liquidity of the Tax Exempt Fund may not be equal to that of a
money market fund which exclusively invests in short-term taxable money market
securities.
    
 
   
In addition, the Tax Exempt Fund expects that substantially all the demand
rights of the Tax Exempt Fund with respect to variable rate demand Municipal
Securities will be supported by letters of credit of major commercial banks.
Fund investors should be aware that banks are subject to extensive governmental
regulation which may limit both the amounts and type of loans and other
financial commitments which may
    
 
                                                                               9
<PAGE>   13
 
be made and interest rates and fees which may be charged. The profitability of
this industry is largely dependent upon the availability and cost of capital
funds for the purpose of financing lending operations under prevailing money
market conditions. Also, general economic conditions play an important part in
the operations of this industry and exposure to credit losses arising from
possible financial difficulties of borrowers might affect a bank's ability to
meet its obligations under a letter of credit.
 
INVESTMENT RESTRICTIONS
 
Each of the Funds is subject to a number of investment restrictions that may be
changed only by a vote of a majority of the outstanding Shares of that Fund (as
defined below under "WHAT ARE MY RIGHTS AS A SHAREHOLDER?").
 
The Government Securities 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, more than 5% of the value of such
        Fund's total assets would be invested in such issuer, or the Fund would
        hold more than 10% of the outstanding voting securities of the issuer,
        except that up to 25% of the value of the Fund's total assets may be
        invested without regard to such limitations. There is no limit to the
        percentage of assets that may be invested in U.S. Treasury bills, notes,
        or other obligations issued or guaranteed by the U.S. Government or its
        agencies or instrumentalities.
 
     2. Purchase any securities which would cause more than 25% of the value of
        such 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) 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.
 
     3. Make loans, other than by entering into repurchase agreements to the
        extent allowed herein and through the purchase of other obligations in
        accordance with its investment objectives and policies.
 
The Tax Exempt Fund will not:
 
     1. Purchase securities, if as a result of such purchase more than 5% of its
        total assets would be invested in the securities of any one issuer
        (other than securities issued or guaranteed by the U.S. Government, its
        agencies or instrumentalities, which securities include project notes
        for purposes of this restriction), except that up to 25% of the value of
        such Fund's assets may be invested without regard to this 5% limitation
        (for purposes of this test, the non-governmental user of facilities
        financed by industrial development or pollution control revenue bonds
        and a bank issuing a letter of credit or comparable guarantee supporting
        a variable rate demand municipal security is considered to be the
        issuer).
 
     2. Purchase the securities of issuers conducting their principal business
        activity in the same industry if as a result of such purchase more than
        25% of its total assets would be invested in the securities of issuers
        in that industry; provided that such limitation shall not apply to the
        purchase of Municipal Securities, securities issued or guaranteed by the
        U.S. Government, its agencies or instrumentalities, or securities issued
        by domestic branches of domestic banks (the only securities issued by
        domestic branches of domestic banks that such Fund contemplates
        investing in are variable rate demand
 
10
<PAGE>   14
 
        Municipal Securities supported by letters of credit or guarantees issued
        by domestic branches of domestic banks).
 
     3. Make loans, other than by entering into repurchase agreements and
        through the purchase of participations in privately negotiated loans and
        portions of publicly issued debt obligations that are in accordance with
        its investment objectives and policies; provided, however, that such
        Fund may not enter into a repurchase agreement if, as a result thereof,
        more than 10% of its total assets would be subject to repurchase
        agreements maturing in more than seven days.
 
In addition, each of the Funds may not borrow money or issue senior securities,
except that a Fund may borrow from banks or enter into reverse repurchase
agreements or dollar roll agreements for temporary purposes in amounts up to 10%
of the value of such Fund's total assets at the time of such borrowing and
except as permitted pursuant to an exemption from the 1940 Act. Each Fund will
not purchase securities while its borrowings (including reverse repurchase
agreements and dollar roll agreements) exceed 5% of its total assets.
 
The following additional investment restriction may be changed without the vote
of a majority of the outstanding Shares of a Fund.
 
Each Fund may not:
 
     1. Purchase or otherwise acquire any securities, if as a result, more than
        10% of the Fund's net assets would be invested in securities that are
        illiquid.
 
- --------------------------------------------------------------------------------
HOW DO I PURCHASE SHARES OF THE FUNDS?
- --------------------------------------------------------------------------------
 
GENERAL
 
Shares of the Funds are sold on a continuing basis without a sales charge at the
net asset value next determined after an order is received by The Ohio Company,
155 East Broad Street, Columbus, Ohio 43215, the Funds' principal underwriter,
and federal funds (monies credited to a member bank's account in a Federal
Reserve Bank) are received by The Ohio Company as hereinafter provided. The
minimum initial investment for individuals is $1,000 and subsequent investments
must be in amounts of at least $100. The Group may, at its discretion, waive the
subsequent investment minimum for purchases effected through the automatic
reinvestment of distributions from unit investment trusts sponsored by The Ohio
Company, and may waive both the initial and subsequent investment minimums for
purchases effected with cash balances in brokerage accounts of customers of The
Ohio Company. Institutions may place orders for any number of individual
accounts with a minimum initial purchase of $1,000 for each individual account.
Subsequent purchases may be made in minimum amounts of $100 for each individual
account. Shares of the Funds may be purchased through a securities dealer,
investment adviser, agent or other fiduciary which may charge a fee for its
services in connection with the purchase. No sales charge is imposed by the
Group or by The Ohio Company.
 
Subsequent purchases of Shares of the Funds may be made by ACH processing as
described under "WHAT OTHER SHAREHOLDER PROGRAMS ARE PROVIDED? -- ACH
Processing" below. In addition, if an Account Information Form has previously
been received by The Ohio Company, Shares may also be purchased by wiring funds
to the Funds as described below under "Purchase by Federal Funds Wire."
 
All Shares purchased will be credited to shareholder accounts after receipt of
an order and federal funds by The Ohio Company, at the net asset value next
determined. Each Fund currently determines net asset value and enters purchases
and redemptions of its Shares as of 4:00 p.m. Eastern Time on each day that the
New York Stock Exchange is open for business and on such other days on which
there is a sufficient degree of trading in that Fund's portfolio securities that
such Fund's net asset value might be materially affected by changes in the value
of the portfolio securities ("Business Day"). If a properly completed order and
federal funds (or other immediately available funds) are received at or prior to
12:00 noon Eastern Time on a
 
                                                                              11
<PAGE>   15
 
Business Day, then the purchase will be entered as of 4:00 p.m. Eastern Time on
that day and dividends will commence on that day. If either federal funds (or
other immediately available funds) or the completed purchase order are received
after 12:00 noon Eastern Time (but prior to 4:00 p.m. Eastern Time) Shares will
be credited to the shareholder's account as of 4:00 p.m. Eastern Time on that
day but will not earn dividends until the following day.
 
The Group reserves the right to reject any order for the purchase of Shares in
whole or in part. You will receive a confirmation of each transaction in your
account, which will also show the total number of Shares being held in
safekeeping by Cardinal Management Corp., the Funds' transfer agent (the
"Transfer Agent"), for your account. Certificates representing Shares will not
be issued.
 
From time to time, The Ohio Company, from its own resources, may also provide
additional compensation to securities dealers in connection with sales of shares
of the Cardinal Funds. Such compensation will include financial assistance to
securities dealers in connection with conferences, sales or training programs
for their employees, seminars for the public, advertising, sales campaigns
and/or shareholder services and programs regarding one or more of the Cardinal
Funds and other dealer-sponsored programs or events. In some instances, this
compensation may be made available only to certain securities dealers whose
representatives have sold or are expected to sell significant amounts of shares
of the Cardinal Funds. Compensation will 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. Securities
dealers may not use sales of a Fund's Shares to qualify for this compensation to
the extent such may be prohibited by the laws of any state or any
self-regulatory agency, such as the National Association of Securities Dealers,
Inc. In addition, The Ohio Company may make ongoing payments to brokerage firms,
financial institutions (including banks) and others to facilitate the
administration and servicing of shareholder accounts. None of the aforementioned
additional compensation is paid for by the Funds or their shareholders.
 
PURCHASE BY FEDERAL FUNDS WIRE
 
   
Investments in Shares of the Funds may be made by wire transfer of federal
funds, avoiding delays of the mail and the normal check clearance process
described below. An investor may telephone the Group at (800) 282-9446, toll
free, prior to wire transfer of his or her investment to advise the Group of the
investment and, if a new investor, to obtain an account number. If an investor
does not telephone the Group for wire instructions and the investor's wire
transfer does not include sufficient information, such purchase will be delayed
until the proper information is received. An investor must instruct its bank to
"wire transfer" the investment immediately to:
    
 
       The Huntington National Bank
       Account Number 01891688407
       Routing Number 044000024
       17 South High Street
       Columbus, Ohio 43215
       Attn: [Name of Applicable Fund]
       [Include Fund Account Number and Name of Account Holder]
 
Funds transmitted by wire will be invested in Shares of the appropriate Fund at
the net asset value next computed after receipt thereof as described above under
"General." A bank may charge for its services in effecting wire transfers of
funds.
 
12
<PAGE>   16
 
PURCHASE BY MAIL
 
Investment in Shares of the Funds may be made by mail by sending a check payable
to the order of the appropriate Fund together with, in the case of an initial
purchase, an Application Form to:
       The Cardinal Group c/o [Name of Applicable Fund]
       155 East Broad Street
       Columbus, Ohio 43215
 
Money transmitted by check drawn on a member of the Federal Reserve System will
normally be converted to federal funds and invested in Shares of the applicable
Fund within one Business Day following receipt by The Ohio Company. Checks drawn
on non-member banks may take considerably longer. THE GROUP STRONGLY RECOMMENDS
THAT INVESTORS OF SUBSTANTIAL AMOUNTS USE FEDERAL FUNDS TO PURCHASE SHARES.
 
AUTOMATIC INVESTMENT PLAN
 
The Group has made arrangements to enable you to make automatic monthly or
quarterly investments, in the minimum amount of $50 per transaction, from your
checking account. Assuming the cooperation of your financial institution, your
checking account therein will be debited to purchase Shares of a Fund on the
periodic basis you select. Confirmation of your purchase of Fund Shares will be
provided by the Transfer Agent. The debit of your checking account will be
reflected in the checking account statement you receive from your financial
institution. Please contact The Ohio Company for the appropriate form.
 
- --------------------------------------------------------------------------------
WHAT DISTRIBUTIONS WILL I RECEIVE?
- --------------------------------------------------------------------------------
 
   
Each Fund's net income is declared as a dividend and accrued on each Business
Day immediately prior to the determination of such Fund's net asset value at
4:00 p.m. Eastern Time. Net investment income (from the time of the immediately
preceding declaration) consists of interest accrued on the portfolio of the Fund
(including accretion of discount and amortization of premium), plus realized net
short-term capital gains (losses) due to portfolio transactions (if any), less
the accrued expenses of that Fund applicable to that dividend period. The Funds
do not expect to realize any long-term capital gains due to their policy of
investing in securities maturing in 397 calendar days or less.
    
 
All dividends of net income are credited to each shareholder's account daily and
automatically reinvested in additional Shares of the applicable Fund at the net
asset value on the last Business Day of each month. Shareholders, however, may
elect to receive monthly dividends of $10 or more declared on their Shares in
cash by checking the appropriate box on the Account Information Form or by
otherwise notifying the Transfer Agent. In addition, investors may obtain cash
at any time without charge by redeeming Shares at net asset value. If the entire
account of a shareholder is withdrawn, all dividends accrued to the time of
withdrawal will be paid at that time.
 
Shareholders may also elect to receive dividends and distributions in cash by
using ACH processing as described under "WHAT OTHER SHAREHOLDER PROGRAMS ARE
PROVIDED? -- ACH Processing" below.
 
Should a Fund incur or anticipate any extraordinary expense, loss or
depreciation which would adversely affect its net asset value per share or
income for a particular period, the Trustees would at that time consider whether
to adhere to the present dividend policy described above or to revise it in
light of the then-prevailing circumstances. For example, if a Fund's net asset
value per share were reduced, or expected to be reduced, below $1.00, the
Trustees might suspend further dividend declarations until the net asset value
returned to $1.00. Thus, extraordinary expenses, losses or depreciation may
result in no dividends being declared for the period during which an investor
holds Shares as well as a redemption price lower than the purchase price for
such Shares.
 
                                                                              13
<PAGE>   17
 
- --------------------------------------------------------------------------------
HOW MAY I REDEEM MY SHARES?
- --------------------------------------------------------------------------------
 
Investors may redeem Shares of a Fund on any Business Day at the net asset value
per share next determined following receipt by the Transfer Agent, 215 East
Capital Street, Columbus, Ohio 43215, of a written or telephonic notice to
redeem, or by check, each as more fully described below. See "HOW IS NET ASSET
VALUE CALCULATED?" below, for a description of when net asset value is
determined.
 
As requested, The Ohio Company, on behalf of a shareholder, will forward the
foregoing notice to redeem to the Transfer Agent without charge. Other
broker-dealers may assist a shareholder in redeeming his Shares and may charge a
fee for such services.
 
Proceeds of redemption requests received by the Transfer Agent in proper form
before (1) 4:00 p.m. Eastern Time for shareholders who are customers of The Ohio
Company and who have submitted their redemption request through their broker at
The Ohio Company or (2) 12:00 noon Eastern Time for all other redemption
requests, will be sent by mail on the next Business Day or, if the expedited
redemption option is available, by federal funds wire on the next Business Day
for use on that day.
 
The Group reserves the right to delay payment for the redemption of Shares where
such Shares were purchased with other than immediately available funds, but only
until the purchase payment has cleared (which may take fifteen or more days from
the date the purchase payment is received by the Fund). The purchase of Fund
Shares by wire transfer of federal funds would avoid any such delay.
 
The Group may suspend the right of redemption or may delay payment during any
period the determination of net asset value is suspended. See "HOW IS NET ASSET
VALUE CALCULATED?".
 
Due to the high cost of maintaining accounts, the Group reserves the right to
redeem involuntarily Shares in any account at the then current net asset value
if at any time redemptions have reduced a shareholder's total investment in a
Fund to a net asset value below $500. A shareholder will be notified in writing
that the value of Fund Shares in the account is less than $500 and allowed not
less than 30 days to increase his investment in that Fund to at least $500
before the redemption is processed. Proceeds of redemptions so processed,
including dividends declared to the date of redemption, will be promptly paid to
the shareholder.
 
REDEMPTION BY MAIL
 
Shareholders may redeem Shares of a Fund by submitting a written request
therefor to the Transfer Agent, at 215 East Capital Street, Columbus, Ohio
43215. The Transfer Agent will request a signature guarantee by an eligible
guarantor institution as described below. However, a signature guarantee will
not be required if (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, provided, however, that the address of record has not been
changed within the preceding 15 days. For purposes of this policy, an "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 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 or (2) it has reason
to believe that the transaction would otherwise be improper.
 
REDEMPTION BY TELEPHONE
 
Shareholders may redeem Shares of a Fund by calling the Group at the telephone
number set forth on the front of this Prospectus. The shareholder may direct
that the redemption proceeds be mailed to the address of record.
 
Neither the Group, the Funds nor their service providers will be liable for any
loss, damages, expense or cost arising out of any telephone redemption effected
in accordance with the Group's telephone redemption procedures, acting upon
instructions reasonably believed to be genuine. The Group will
 
14
<PAGE>   18
 
employ procedures designed to provide reasonable assurances that instructions by
telephone are genuine; if these procedures are not followed, the Group, the
Funds or their service providers may be liable for any losses due to
unauthorized or fraudulent instructions. These procedures may include recording
all phone conversations, sending confirmations to shareholders within 72 hours
of the telephone transaction, and verification of account name and account
number or tax identification number. If, due to temporary adverse conditions,
investors are unable to effect telephone transactions, shareholders may also
redeem their Shares by mail as described above.
 
EXPEDITED REDEMPTION
 
Any investor may elect to use the expedited redemption procedure by designating
on the Account Information Form submitted at the time of initial investment the
name of a commercial bank and account number to receive proceeds of redemption.
If this election is made, requests for redemption may be made by mail or by
telephone as described above.
 
An investor may elect to have redemption proceeds sent by federal funds wire to
the designated U.S. bank account if the proceeds are $1,000 or more. Otherwise,
proceeds will be sent by mail. No signature guarantee will be required of
investors electing this procedure. Requests to change bank or account
designations may only be made in writing to the Group with the type of signature
guarantee and other documentation specified under "Redemption by Mail" above. To
participate in this procedure, an investor must complete the expedited
redemption portion of the Account Information Form or notify the Group at any
time after making an initial investment.
 
An investor may also elect to have redemption proceeds sent by federal funds
wire to The Ohio Company, the Funds' distributor, if the proceeds are $500 or
more. If the investor elects to have federal funds so wired, the investor may
pick up a check at The Ohio Company's main office at 155 East Broad Street,
Columbus, Ohio or The Ohio Company will mail a check to the investor's address
of record. The Group may, at its discretion, waive the minimum redemption
requirement for redemptions effected to cover debit balances in brokerage
accounts of customers of The Ohio Company.
 
AUTOMATIC WITHDRAWAL
 
Shareholders may elect to have the proceeds from redemptions of Shares
transmitted to an authorized bank account at a Federal Reserve member bank
through ACH processing as described under "WHAT OTHER SHAREHOLDER PROGRAMS ARE
PROVIDED? - ACH Processing" below.
 
SYSTEMATIC WITHDRAWAL PLAN
 
As a shareholder, you may elect to redeem your Shares monthly or quarterly in
amounts of $50 or more, pursuant to the Group's Systematic Withdrawal Plan.
Please contact The Ohio Company for the appropriate form.
 
CHECK-WRITING REDEMPTION PROCEDURE
 
   
The Transfer Agent will provide any shareholder who so requests with a supply of
checks, imprinted with the shareholder's name, which may be drawn against the
appropriate Fund's account maintained by The Fifth Third Bank (the "Bank"), for
redemption of Fund Shares. These checks may be made payable to the order of any
person in any amount. To participate in this procedure, an investor must
complete the Check-Writing Redemption Form available from the Transfer Agent.
When a check is presented to the Bank for payment, the Transfer Agent (as your
agent) will cause such Fund to redeem sufficient Shares in your account to cover
the amount of the check. Shares continue earning daily dividends until the day
on which the check is presented to the Bank for payment. Cancelled checks will
be returned to you. Due to the delay caused by the requirement that redemptions
be priced at the next computed net asset value, the Bank will
    
 
                                                                              15
<PAGE>   19
 
only accept for payment checks presented through normal bank clearing channels.
Shareholders should not attempt to withdraw the full amount of an account or to
close out an account by using this procedure.
 
No charge will be made to a shareholder for participation in the check-writing
redemption procedure or for the clearance of any checks. However, charges for
copies ($5 each), returned checks ($15 each) and returned items of deposit ($15
each) will be deducted from a shareholder's account.
 
In order to stop payment on a check, the shareholder must notify the Group in
writing before the check has been presented to the Bank for payment. A charge of
$15 will be deducted from the shareholder's account for each stop payment order.
 
- --------------------------------------------------------------------------------
WHAT OTHER SHAREHOLDER PROGRAMS ARE PROVIDED?
- --------------------------------------------------------------------------------
 
ACH PROCESSING
 
The Funds offer ACH privileges. Investors may use ACH processing to make
subsequent purchases, redeem Shares and/or electronically transfer distributions
paid on Fund Shares, in addition to the other methods described in this
Prospectus. ACH provides a method by which funds may be automatically
transferred to or from an authorized bank account at a Federal Reserve member
bank that is an ACH member. Please contact your representative if you are
interested in ACH processing.
 
EXCHANGE PRIVILEGE
 
   
Shareholders of a Fund may, provided the amount to be exchanged meets the
applicable minimum investment requirements and the exchange is made in states
where it is legally authorized, exchange Shares of a Fund for Shares of the
other Fund (without payment of any sales charge) or for Investor shares (upon
the payment of the applicable sales charge) or Institutional shares (if the
investor is otherwise eligible to acquire Institutional shares) of:
    
 
     Cardinal Aggressive Growth Fund,
     an equity fund seeking appreciation of
     capital;
 
     Cardinal Balanced Fund,
     a fund seeking current income and long-term
     growth of both capital and income;
 
     The Cardinal Fund,
     an equity fund seeking long-term growth
     of capital and income; or
 
   
     Cardinal Government Obligations Fund,
     a fund investing in securities issued
     or guaranteed by the U.S. Government.
    
 
   
Notwithstanding the foregoing and subject to the limitations contained in the
following paragraph, exchanges of Fund Shares for Investor shares of The
Cardinal Fund, Cardinal Government Obligations Fund, Cardinal Balanced Fund or
Cardinal Aggressive Growth Fund (individually, a "Cardinal Load Fund") generally
may be completed upon the payment of a sales charge equal to the sales charge
payable upon purchase of Investor shares of that Cardinal Load Fund. If,
however, the Shares of a Fund to be exchanged were acquired as a result of an
exchange of shares of a Cardinal Load Fund, the sales charge to be paid on the
present exchange may be reduced by the sales charge previously paid.
    
 
The foregoing exchange privilege must be made by written or telephonic
authorization. A shareholder should notify The Ohio Company of his desire to
make an exchange, and The Ohio Company will furnish, as necessary, a prospectus
and an application form to open the account. The Transfer Agent will require
 
16
<PAGE>   20
 
   
that any written authorization of an exchange include a signature guarantee as
described above under "HOW MAY I REDEEM MY SHARES? -- Redemption by mail."
However, a signature guarantee will not be required if the exchange is requested
to be made within the same account or into an existing account of the
shareholder held in the same name or names and in the same capacity as the
account from which the exchange is to be made. Shareholders may also authorize
an exchange of Shares of a Fund by telephone. Neither the Group, the Funds nor
any of their service providers will be liable for any loss, damages, expense or
cost arising out of any telephone exchange authorization to the extent and
subject to the requirements set forth under "HOW MAY I REDEEM MY SHARES? --
Redemption by telephone" above.
    
 
For tax purposes, an exchange is treated as a redemption and a new purchase.
 
The Group may, at any time, modify or terminate the foregoing exchange
privilege. The Group, however, will give shareholders of the Funds 60 days'
advance written notice of any such modification or termination.
 
- --------------------------------------------------------------------------------
HOW IS NET ASSET VALUE CALCULATED?
- --------------------------------------------------------------------------------
 
The Funds' net asset value per share is currently determined as of 4:00 p.m.
Eastern Time on each Business Day. Net asset value per share is computed by
dividing the total value of the assets of a Fund, less its liabilities, by the
total number of Shares outstanding. Expenses and fees of the Funds, including
the management fee, are accrued daily and taken into account for the purpose of
determining the net asset value.
 
The Board of Trustees has adopted a policy requiring each Fund to use its best
efforts, under normal circumstances, to maintain a constant net asset value of
$1.00 per share. Each Fund values its portfolio securities by the amortized cost
method which involves valuing a security at its cost and thereafter accruing any
discount or premium at a constant rate to maturity. A Fund will normally include
any accrued discount or premium in its daily dividend and will thereby keep
constant the value of the Fund's assets and, consequently, its net asset value
per share. This method does not take into account unrealized capital gains or
losses or the effect of fluctuating interest rates.
 
- --------------------------------------------------------------------------------
DO THE FUNDS PAY FEDERAL INCOME TAX?
- --------------------------------------------------------------------------------
 
   
Each of the funds of the Group, including the Funds, is treated as a separate
entity for federal income tax purposes and each intends to qualify as a
"regulated investment company" under the Internal Revenue Code of 1986, as
amended (the "Code"), for so long as such qualification is in the best interest
of that fund's shareholders. Qualification as a regulated investment company
under the Code requires, among other things, that the regulated investment
company distribute to its shareholders at least 90% of its investment company
taxable income. Each Fund contemplates declaring as dividends 100% of that
Fund's investment company taxable income (before deduction of dividends paid).
    
 
A non-deductible 4% excise tax is imposed on regulated investment companies that
do not distribute in each calendar year (regardless of whether they otherwise
have a non-calendar taxable year) an amount equal to 98% of their ordinary
income for the calendar year plus 98% of their capital gain net income for the
one-year period ending on October 31 of such calendar year. The balance of such
income must be distributed during the next calendar year. If distributions
during a calendar year were less than the required amount, the Fund would be
subject to a nondeductible excise tax equal to 4% of the deficiency.
 
- --------------------------------------------------------------------------------
WHAT ABOUT MY TAXES?
- --------------------------------------------------------------------------------
 
THE GOVERNMENT SECURITIES FUND
 
It is expected that the Government Securities Fund will distribute annually to
shareholders all or substantially all of that Fund's net ordinary income and net
realized capital gains and that such distributed net ordinary income and
distributed net realized capital gains will be taxable income to shareholders
for
 
                                                                              17
<PAGE>   21
 
federal income tax purposes, even if paid in additional Shares of the Government
Securities Fund and not in cash. Since all of the Government Securities Fund's
net investment income is expected to be derived from earned interest and
short-term capital gains, it is anticipated that no part of any distribution
will be eligible for the dividends received deduction for corporations. The
Government Securities Fund does not expect to realize any long-term capital
gains and, therefore, does not foresee paying any "capital gains dividends" as
described in the Code. However, if the Government Securities Fund were to
realize any long-term capital gains, distribution by such Fund of the excess of
any such net long-term capital gain over net short-term capital loss is taxable
to shareholders as long-term capital gain in the year in which it is received,
regardless of how long the shareholder has held the Shares. Such distributions
are not eligible for the dividends received deduction.
 
Even though a substantial portion of distributions of net income will be
attributable to interest on U.S. Government obligations, which may be exempt
from state or local tax if received directly by a shareholder, shareholders of
the Government Securities Fund may be subject to state and local taxes with
respect to their ownership of that Fund's Shares or distributions from the
Government Securities Fund.
 
THE TAX EXEMPT FUND
 
FEDERAL TAXES. The Tax Exempt Fund will distribute substantially all of its net
investment income and net capital gains to shareholders. Dividends derived from
interest earned on Municipal Securities the interest on which is excluded from
gross income for federal income tax purposes, including insurance proceeds
representing maturing interest on defaulted Municipal Securities the interest on
which would be so excluded, constitute "exempt-interest dividends" when
designated as such by the Tax Exempt Fund and will be excluded from gross income
for federal income tax purposes. However, interest excluded from gross income
for federal income tax purposes that is received by individuals and corporations
on certain municipal obligations issued on or after August 8, 1986, to finance
certain private activities will be treated as a tax preference item in computing
the alternative minimum tax. It is likely that exempt-interest dividends
received by shareholders from the Tax Exempt Fund will also be treated as tax
preference items in computing the alternative minimum tax to the extent, if any,
that distributions by the Tax Exempt Fund are attributable to interest earned by
the Tax Exempt Fund on such obligations. Also, a portion of all other interest
excluded from gross income for federal income tax purposes earned by a
corporation may be subject to the alternative minimum tax as a result of the
inclusion in alternative minimum taxable income of 75% of the excess of adjusted
current earnings over adjusted net book income.
 
Distributions, if any, derived from capital gains will generally be taxable to
shareholders as capital gains for federal income tax purposes to the extent so
designated by the Tax Exempt Fund. Dividends, if any, derived from sources other
than interest excluded from gross income for federal income tax purposes and
capital gains will be taxable to shareholders as ordinary income for federal
income tax purposes whether or not reinvested in additional Shares. Shareholders
not subject to federal income tax on their income will not, of course, be
required to pay federal income tax on any amounts distributed to them. The Tax
Exempt Fund anticipates that substantially all of its dividends will be excluded
from gross income for federal income tax purposes and will not be a preference
item for individuals for purposes of the federal alternative minimum tax.
 
   
If a shareholder receives an exempt-interest dividend with respect to any Share
and such Share is held by the shareholder for six months or less, any loss on
the sale or exchange of such Share will be disallowed to the extent of the
amount of such exempt-interest dividend. In certain limited instances, the
portion of Social Security benefits that may be subject to federal income
taxation may be affected by the amount of tax-exempt interest income, including
exempt-interest dividends, received by a shareholder.
    
 
STATE AND LOCAL TAXES. Under state or local law, distributions of net investment
income may be taxable to shareholders as dividend income even though a
substantial portion of such distribution may be derived from interest excluded
from gross income for federal income tax purposes that, if received directly,
would be exempt from such income taxes. The Tax Exempt Fund will report to its
shareholders annually after the
 
18
<PAGE>   22
 
close of its taxable year the percentage and source, on a state-by-state basis,
of interest income earned on Municipal Securities held by the Tax Exempt Fund
during the preceding year.
 
GENERAL
 
The foregoing is intended only as a brief summary of some of the important tax
considerations generally affecting the Funds and their shareholders. Potential
investors in a Fund are urged to consult their tax advisers concerning the
application of federal, state and local taxes as such laws and regulations
affect their own tax situation.
 
The Transfer Agent will inform shareholders at least annually of the amount and
nature of such income and capital gains.
 
- --------------------------------------------------------------------------------
WHO MANAGES MY INVESTMENT IN THE FUNDS?
- --------------------------------------------------------------------------------
 
   
Except where shareholder action is required by law, all of the authority of the
Group is exercised under the direction of the Group's Trustees. Unless so
required by the Group's Declaration of Trust or By-Laws or by Ohio law, at any
given time all of the Trustees may not have been elected by the shareholders of
the Group. The Trustees are empowered to elect officers and contract with and
provide for the compensation of agents, consultants and other professionals to
assist and advise it in its day-to-day operations. The Group will be managed in
accordance with its Declaration of Trust and the laws of Ohio governing business
trusts.
    
 
   
The Trustees of the Group 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 the Adviser or The Ohio Company receives any compensation
from the Group for acting as a Trustee of the Group. The officers of the Group
receive no compensation directly from the Group for performing the duties of
their offices. The Adviser receives fees from the Group for acting as investment
adviser and manager and as dividend and transfer agent and for providing certain
fund accounting services. The Ohio Company receives no fees under its
Distribution Agreement with the Group from the Funds.
    
 
INVESTMENT ADVISER AND MANAGER
 
Cardinal Management Corp. (the "Adviser"), 155 East Broad Street, Columbus, Ohio
43215, a wholly owned subsidiary of The Ohio Company, is the investment adviser
and manager of each of the Funds. The Adviser is also the investment adviser and
manager of each of the other Cardinal Funds.
 
The Ohio Company, an investment banking firm organized in 1925, is a member of
the New York and Chicago Stock Exchanges, other regional stock exchanges and the
National Association of Securities Dealers, Inc. Descendants of H.P. and R.F.
Wolfe, deceased, and members of their families, through their possession of a
majority of voting stock, may be considered controlling persons of The Ohio
Company. The Ohio Company serves as principal underwriter for each of the
Cardinal Funds.
 
In its capacity as investment adviser, and subject to the ultimate authority of
the Group's Board of Trustees, the Adviser, in accordance with the Funds'
investment objectives and policies, manages each Fund, and makes decisions with
respect to and places orders for all purchases and sales of its portfolio
securities. John R. Carle has been primarily responsible for the day-to-day
management of the portfolio of the Government Securities Fund since the date of
the Reorganization. Prior to the Reorganization and since December 22, 1995, Mr.
Carle was primarily responsible for the day-to-day management of the portfolio
of CGST, the Government Securities Fund's predecessor. Mr. Carle has been a
portfolio manager with the Adviser and/or The Ohio Company since 1971 and has
more than 28 years of management experience.
 
David C. Will has been primarily responsible for the day-to-day management of
the portfolio of the Tax Exempt Fund since the date of the Reorganization. Prior
to the Reorganization and since December 22, 1995, Mr. Will was primarily
responsible for the day-to-day management of the portfolio of CTEMT, the Tax
 
                                                                              19
<PAGE>   23
 
Exempt Fund's predecessor. Mr. Will has been a Vice President of the Adviser and
The Ohio Company since 1990 and has more than 25 years of investment management
experience.
 
In addition, pursuant to the Investment Advisory Agreement, the Adviser
generally assists in all aspects of the Funds' administration and operation.
 
For the services provided and expenses assumed pursuant to its investment
advisory agreement with the Group with respect to the Funds, the Adviser
receives a fee from each Fund, computed daily and paid monthly at the annual
rate of .50% of average net daily assets of that Fund. The Adviser may
periodically waive all or a portion of its advisory fee with respect to a Fund
to increase the net income of that Fund available for distributions as
dividends. The waiver of such fee will cause the yield of such Fund to be higher
than it would otherwise be in the absence of such waiver.
 
DIVIDEND AND TRANSFER AGENT AND FUND ACCOUNTANT
 
   
The Group has entered into a Transfer Agency and Fund Accounting Agreement with
Cardinal Management Corp. (the "Transfer Agent"), 215 East Capital Street,
Columbus, Ohio 43215, pursuant to which the Transfer Agent has agreed to act as
the Funds' transfer agent and dividend disbursing agent. In consideration of
such services, each Fund has agreed to pay the Transfer Agent an annual fee,
paid monthly, equal to $21 per shareholder account plus out-of-pocket expenses.
In addition, the Transfer Agent provides certain fund accounting services for
the Funds. The Transfer Agent receives a fee from each Fund for such services
equal to a fee computed daily and paid periodically at an annual rate of .03% of
that Fund's average daily net assets of up to $100 million and .01% of such

WHAT ARE MY RIGHTS AS A SHAREHOLDER?
- --------------------------------------------------------------------------------
 
   
The Group was organized as an Ohio business trust on March 23, 1993. The Group
currently consists of six funds. The other funds of the Group are The Cardinal
Fund, Cardinal Government Obligations Fund, Cardinal Balanced Fund and Cardinal
Aggressive Growth Fund. The shares of each fund of the Group, other than the
Funds, are currently offered in two separate classes: Investor A shares,
otherwise referred to as Investor Shares, and Investor Y shares, otherwise
referred to as Institutional Shares. The Funds each have only one class of
shares. Each share represents an equal proportional interest in a fund with
other shares of
    
 
20
<PAGE>   24
 
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.
 
Shareholders are entitled to one vote for each dollar of value invested and a
proportionate fractional vote for any fraction of a dollar invested, and will
vote in the aggregate and not by series except as otherwise expressly required
by law. For example, shareholders of the Government Securities 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 accountants.
However, shareholders of the Government Securities Fund will vote as a fund, and
not in the aggregate with other shareholders of the Group, for purposes of
approval of amendments to the investment advisory agreement as it relates to the
Government Securities Fund or any of the Government Securities Fund's
fundamental policies.
 
   
Overall responsibility for the management of the Funds is vested in the Board of
Trustees of the Group. See "WHO MANAGES MY INVESTMENT OF THE FUNDS?" Individual
Trustees are elected by the shareholders of the Group, although Trustees may
under certain circumstances fill vacancies, including vacancies created by
expanding the size of the Board. Trustees 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 Ohio law. See "ADDITIONAL INFORMATION --
Miscellaneous" in the Statement of Additional Information for further
information.
    
 
An annual or special meeting of shareholders to conduct necessary business is
not required by the Declaration of Trust, the 1940 Act or other authority
except, under certain circumstances, to elect Trustees, amend the Declaration of
Trust, approve the investment advisory agreement and to satisfy certain other
requirements. To the extent that such a meeting is not required, the Group does
not intend to have an annual or special meeting.
 
The Group has represented to the Commission 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 and that the Group will
assist in communications with other shareholders as required by Section 16(c) of
the 1940 Act. At such 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 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 a 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 the 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 the Fund.
 
Shareholders should direct all inquiries concerning such matters to the Transfer
Agent in writing to 215 East Capital Street, Columbus, Ohio 43215, or by calling
(800) 282-9446.
 
   
Shareholders will receive unaudited semi-annual reports describing the
investment operations of the Funds and annual financial reports audited by
independent auditors.

                                 will be invested in fixed income senior securities. (See

                                 equal to 4.50% of the public offering price (4.71% of net
                                 amount invested) reduced on investments of $100,000 or

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
   
From time to time each Fund may advertise its average annual total return,
cumulative total return and/or yield. SUCH TOTAL RETURN FIGURES AND YIELD
FIGURES ARE BASED UPON HISTORICAL EARNINGS AND ARE NOT INTENDED TO INDICATE
FUTURE PERFORMANCE. The average annual total return advertised by a Fund refers
to the return generated by an investment in that Fund over certain specified
periods since the establishment of such Fund. The average annual total return
over a period equates the amount of an initial investment in the Fund to the
amount redeemable at the end of that period assuming that any dividends and
distributions earned by an investment in the Fund are immediately reinvested and
the maximum applicable sales charge, if any, is deducted from the initial
investment at the time of investment. Such figure is then annualized. The
cumulative total return advertised refers to the total return on a hypothetical
investment over the relevant period and equates the amount of an initial
investment in the Fund to the amount redeemable at the end of that period
assuming that any dividends and distributions are immediately reinvested and the
maximum sales charge, if any, is deducted from the initial investment.
    
 
                                        8
<PAGE>   39
 
Yield will be computed by dividing a Fund's net investment income per share
earned during a recent one-month period by such 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.
If the sales charge were not deducted, the average annual total return,
cumulative total return and yield advertised would be higher.
 
In addition, from time to time the Balanced Fund may include in its sales
literature and shareholder reports a quote of the current "distribution" rate
for such Fund. A distribution rate is simply a measure of the level of dividends
distributed for a specified period and is computed by dividing the total amount
of dividends per share paid by the Balanced Fund during the past 12 months by a
current maximum offering price. It differs from yield, which is a measure of the
income actually earned by the Balanced Fund's investments, and from total
return, which is a measure of the income actually earned by, plus the effect of
any realized and unrealized appreciation or depreciation of, such investments
during a stated period. A distribution rate is, therefore, not intended to be a
complete measure of performance. A distribution rate may sometimes be greater
than yield since, for instance, it may include short-term and possibly long-term
gains (which may be non-recurring), may not include the effect of amortization
of bond premiums and does not reflect unrealized gains or losses.
 
   
Investors may also judge the performance of a Fund by comparing or referencing
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 such as those prepared by Dow Jones & Co., Inc.
and Standard & Poor's Corporation, and to data prepared by Lipper Analytical
Services, Inc. and Morningstar, Inc. Comparisons may also be made to indices or
data published in Money Magazine, Forbes, Barron's, The Wall Street Journal, The
New York Times, The Columbus Dispatch, Business Week, U.S.A. Today and Consumer
Reports. In addition to performance information, general information about a
Fund that appears in a publication such as those mentioned above may be included
in advertisements and in reports to shareholders.
    
 
   
Further information about the performance of each Fund is contained in that
Fund's Annual Report to Shareholders which may be obtained without charge by
contacting the Group at the telephone number set forth on the cover page of this
Prospectus. Performance quotations will be computed separately for Investor and
Institutional Shares. Because of differences in the fees and/or expenses borne
by Institutional and Investor Shares, the net yield and total return on each
class can be expected, at any given time, to differ from the net yield and total
return of the other class.

WHAT ARE THE FUNDS?
- --------------------------------------------------------------------------------
 
   
Each Fund is one separate diversified investment fund of the Group, which was
organized on March 23, 1993, as an Ohio business trust. The Group is registered
and operates as an open-end management investment company as defined in the
Investment Company Act of 1940, as amended (the "1940 Act"). The Cardinal Fund
was organized for the purposes of acquiring all of the assets and liabilities of
TCFI to effect a reorganization of TCFI from a stand alone investment company to
a separate series of the Group (the "Reorganization"). The Reorganization was
effected as of May 1, 1996.

- --------------------------------------------------------------------------------
 
IN GENERAL
 
The investment objectives of The Cardinal Fund are to achieve long-term growth
of capital and income. Current income is a secondary objective. The Cardinal
Fund seeks to achieve its objectives through selective participation in the
long-term progress of businesses and industries.
 
The investment objectives of the Balanced Fund are to seek current income and
long-term growth of both capital and income. The Balanced Fund intends to invest
based on combined considerations of risk, income and capital enhancement.

The investment objective of the Aggressive Growth Fund is to seek appreciation
of capital. The Aggressive Growth Fund will invest primarily in common stocks
and securities convertible into common stocks of growth oriented companies.
 
The investment objectives of each Fund are fundamental policies and as such may
not be changed without a vote of the holders of a majority of the outstanding
Shares of that Fund (as defined below under "WHAT ARE MY RIGHTS AS A
SHAREHOLDER?"). No Fund is intended to provide a complete and balanced
investment program for an investor. There can be no assurance that the
investment objectives of any Fund will be achieved.
 
THE CARDINAL FUND
 
The policy of The Cardinal Fund is generally to invest in equity securities of
companies which, in the opinion of the Adviser, are growth oriented. The
securities purchased by The Cardinal Fund are traded in either established
over-the-counter markets or on national exchanges and are issued by companies
having a market capitalization of at least $10 million. This policy of normally
investing in equity securities believed to have a potential for long-term
capital appreciation means that the assets of The Cardinal Fund will generally
be subject to greater risk than may be involved in securities which do not have
such growth characteristics. It is recognized, however, that there may be times
when, as a temporary, defensive measure, The Cardinal Fund's equity position
should be reduced. At such times, and otherwise for cash management purposes,
The Cardinal Fund may hold its assets in cash or invest its assets in investment
grade debt securities, U.S. Government securities, securities of other
investment companies, repurchase agreements and preferred stock.
 
THE BALANCED FUND
 
   
Under normal market conditions the Balanced Fund will invest in common stocks,
preferred stocks, fixed income securities and securities convertible into common
stocks (i.e., warrants, rights, convertible preferred stock, fixed rate
preferred stock and convertible fixed-income securities). At least 25% of the
value of the Balanced Fund's assets will be invested in fixed income senior
securities. For purposes of compliance with such 25% limitation, only that
portion of any convertible senior security attributable to its fixed income
characteristics will be used. By investing primarily in common stocks the
Balanced Fund will pursue its objectives of long-term growth of both capital and
income. However, the Balanced Fund, through its fixed-income and convertible
securities as well as the dividend attributes of certain of its common and
preferred stock holdings will place considerable emphasis on generating current
income.
    
 
   
The common and preferred stocks and securities convertible into common stocks
will be selected if the Adviser believes that such securities can contribute to
the Balanced Fund's objectives of providing current income and growth in income
and/or long-term growth of capital. The Balanced Fund will invest in the common
and preferred stocks and securities convertible into common stocks of domestic
issuers and foreign issuers (subject to the limitations described below), with
market capitalizations of not less than $10 million and which are generally
traded either in established over-the-counter markets or on national exchanges.
As described below, however, the Balanced Fund may invest in privately placed or
restricted securities.
    
 
The Adviser will select convertible securities primarily upon its evaluation
that the underlying common stocks meet the criteria for selection of common
stocks as described above. The Balanced Fund may invest up to 10% of its net
assets in non-investment grade convertible debt securities rated no lower than
"B" by an appropriate nationally recognized statistical rating organization (an
"NRSRO") or in unrated securities which are deemed by the Adviser to be of
comparable quality. Non-investment grade securities are commonly referred to as
high yield or high risk securities. High yield, high risk securities are
generally riskier than higher quality securities and are subject to more credit
risk, including risk of default, and volatility than higher quality securities.
In addition, such securities have less liquidity and experience more price
fluctuation than higher quality securities.
 
                                       10
<PAGE>   41
 
Convertible debt securities which are rated "B" by Moody's Investor Services
("Moody's") generally lack characteristics of a desirable investment, since the
assurance of interest and principal payments or maintenance of other terms of
the contract over any long period of time may be small. Debt rated "B" by
Standard & Poor's Corporation ("S&P") is regarded, on balance, as predominantly
speculative with respect to capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such debt will likely have
some quality and protective characteristics, these are outweighed by large
uncertainties or major risk exposures to adverse conditions. In the event that a
convertible debt security's rating falls below a "B" by the appropriate NRSROs,
the Adviser will reevaluate the security in order to determine whether to sell
or convert, if possible, such security. In such an event, however, the Balanced
Fund would not be required to liquidate such security if it would suffer a loss
on the sale of such security.
 
The Balanced Fund's fixed income senior securities consist of bonds, debentures,
notes, zero-coupon securities, mortgage-related securities, obligations issued
or guaranteed by the U.S. Government or its agencies or instrumentalities,
certificates of deposit, time deposits, high quality commercial paper and
bankers' acceptances. The Balanced Fund may also invest in repurchase
agreements.
 
The Balanced Fund expects to invest in a variety of bills, notes and bonds
issued by the U.S. Treasury, differing in their interest rates, maturities, and
times of issuance, as well as "stripped" U.S. Treasury obligations such as
Treasury Receipts issued by the U.S. Treasury representing either future
interest or principal payments, and other obligations issued or guaranteed by
the U.S. Government or its agencies or instrumentalities. Stripped securities
are issued at a discount to their "face value" and may exhibit greater price
volatility than ordinary debt securities because of the manner in which their
principal and interest are returned to investors. Certain of such U.S.
Government obligations may have variable or floating rates of interest, whose
value on the adjustment of its interest rate can reasonably be expected to
approximate its par value. However, in the event the interest rate of such
security is tied to an index or interest rate that may from time to time lag
behind other market interest rates, there is the risk that such security's
market value, upon adjustment of its interest rate, will not approximate its par
value. 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, 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 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. The Balanced Fund
will invest in the obligations of such agencies or instrumentalities only when
the Adviser believes that the credit risk with respect thereto is minimal.
 
   
The Balanced Fund also expects to invest in bonds, notes and debentures of a
wide range of U.S. corporate issuers. Such obligations may be secured or
unsecured promises to pay and will in most cases differ in their interest rates,
maturities and times of issuance.
    
 
   
The Balanced Fund will invest only in corporate fixed income senior securities
which are rated at the time of purchase within the four highest rating groups
assigned by an appropriate NRSRO (which are considered to be investment grade)
or, if unrated, which the Adviser deems to be of comparable quality. For a
description of the rating symbols of the NRSROs, see the Appendix to the
Statement of Additional Information. For a discussion of debt securities rated
within the fourth highest rating group assigned by an NRSRO, see "Risk Factors
and Investment Techniques -- General" below.
    
 
Under normal market conditions, the Balanced Fund may hold up to 10% of the
value of its total assets in short-term obligations (with maturities of 12
months or less) consisting of domestic commercial paper, bankers' acceptances,
certificates of deposit and time deposits of U.S. banks and repurchase
agreements.
 
                                       11
<PAGE>   42
 
The Balanced Fund may also invest in securities of other investment companies,
as further described below, and in income participation loans.
 
The Balanced Fund may invest in obligations of the Export-Import Bank of the
United States, in U.S. dollar denominated international securities for which the
primary trading market is in the United States ("Yankee Securities"), or for
which the primary trading market is abroad ("Eurodollar Securities"), and in
Canadian Bonds and bonds issued by institutions organized for a specific
purpose, such as the World Bank and the European Economic Community, by two or
more sovereign governments ("Supranational Agency Bonds").
 
   
The Balanced Fund may also invest in mortgage-related securities issued or
guaranteed by the U.S. Government or its agencies or instrumentalities or by
nongovernmental entities which are rated, at the time of purchase, within the
four highest bond rating categories assigned by an appropriate NRSRO, or, if
unrated, which the Adviser deems to be of comparable quality. Under normal
market conditions, the Balanced Fund's investment in mortgage-related securities
will not exceed 25% of the value of its total assets. Such mortgage-related
securities have mortgage obligations backing such securities, including among
others, conventional thirty year fixed rate mortgage obligations, graduated
payment mortgage obligations, fifteen year mortgage obligations and adjustable
rate mortgage obligations. All of these mortgage obligations can be used to
create pass-through securities. A pass-through security is created when mortgage
obligations are pooled together and undivided interests in the pool or pools are
sold. The cash flow from the mortgage obligations is passed through to the
holders of the securities in the form of periodic payments of interest,
principal and prepayments (net of a service fee). Prepayments occur when the
holder of an individual mortgage obligation prepays the remaining principal
before the mortgage obligation's scheduled maturity date. As a result of the
pass-through of prepayments of principal on the underlying securities,
mortgage-backed securities are often subject to more rapid prepayment of
principal than their stated maturity would indicate. Because the prepayment
characteristics of the underlying mortgage obligations vary, it is not possible
to predict accurately the realized yield or average life of a particular issue
of pass-through certificates. Prepayment rates are important because of their
effect on the yield and price of the securities. Accelerated prepayments have an
adverse impact on yields for pass-throughs purchased at a premium (i.e., a price
in excess of principal amount) and may involve additional risk of loss of
principal because the premium may not have been fully amortized at the time the
obligations are repaid. The opposite is true for pass-throughs purchased at a
discount. The Balanced Fund may purchase mortgage-related securities at a
premium or a discount. Reinvestment of principal payments may occur at higher or
lower rates than the original yield on such securities. Due to the prepayment
feature and the need to reinvest payments and prepayments of principal at
current rates, mortgage-related securities can be less effective than typical
bonds of similar maturities at maintaining yields during periods of declining
interest rates.
    
 
Also included among the mortgage-related securities that the Balanced Fund may
purchase are collateralized mortgage obligations ("CMOs") and real estate
mortgage investment conduits ("REMICs"). CMOs may be collateralized by whole
mortgage loans but are more typically collateralized by portfolios of mortgage
pass-through securities guaranteed by the Government National Mortgage
Association, the Federal Home Loan Mortgage Corporation or the Federal National
Mortgage Association, and their income streams. Certain CMOs and REMICs are
issued by private issuers. Such securities may be eligible for purchase by the
Balanced Fund if (1) the issuer has obtained an exemptive order from the
Securities and Exchange Commission regarding purchases by investment companies
of equity interests of other investment companies or (2) such purchase is within
the limitations imposed by Section 12 of the 1940 Act.
 
The Balanced Fund may also invest in asset-backed securities such as
Certificates of Automobile Receivables ("CARS") and Certificates of Amortized
Revolving Debts ("CARDS"), each of which must be rated at the time of purchase
within the four highest rating groups assigned by Moody's or S&P. For a
description of the fourth highest rating group, see "Risk Factors and Investment
Techniques" below.
 
                                       12
<PAGE>   43
 
The amount invested in stocks, bonds and short-term obligations may be varied
from time to time, depending upon the Adviser's assessment of business, economic
and market conditions, including any potential advantage of price shifts between
the stock market and the bond market. The Balanced Fund reserves the right to
hold short-term securities in whatever proportion deemed desirable for temporary
defensive periods during adverse market conditions as determined by the Adviser.
However, to the extent that the Balanced Fund is so invested, its investment
objectives may not be achieved during that time.
 
THE AGGRESSIVE GROWTH FUND
 
In determining the securities to be purchased by the Aggressive Growth Fund,
emphasis will be placed on securities of companies which, in the opinion of the
Adviser, are growth oriented and exhibit the potential for above-average growth
in earnings. The securities to be purchased by the Aggressive Growth Fund are
traded either in established over-the-counter markets or on national exchanges
and are issued by companies having a market capitalization of at least $10
million.
 
   
The Adviser will select convertible securities primarily upon its evaluation
that the underlying common stocks meet the criteria for selection of common
stocks as described above. The Aggressive Growth Fund may invest up to 10% of
its net assets in non-investment grade convertible debt securities rated no
lower than B by an appropriate NRSRO or in unrated securities which are deemed
by the Adviser to be of comparable quality. Non-investment grade securities are
commonly referred to as high yield or high risk securities. The characteristics
and risks associated with such high risk securities are discussed more fully
above under "The Balanced Fund." In the event that a convertible debt security's
rating falls below a "B" by an NRSRO, the Adviser will reevaluate the security
in order to determine whether to sell or convert, if possible, such security. In
such an event, however, the Aggressive Growth Fund would not be required to
liquidate such security if it would suffer a loss on the sale of such security.
    
 
The Aggressive Growth Fund will, under normal market conditions, be invested
fully in common stocks and securities convertible into common stocks and may
engage in the investment techniques more fully described below. However, for
cash management purposes the Adviser may invest a portion of the Aggressive
Growth Fund's assets in short-term fixed income securities, consisting of
commercial paper, bankers' acceptances, certificates of deposit, obligations
issued or guaranteed by the U.S. Government or its agencies or
instrumentalities, demand and time deposits of domestic banks, repurchase
agreements and securities of other investment companies, as described below.
During temporary defensive periods, as determined by the Adviser, the Aggressive
Growth Fund may hold up to 100% of its total assets in such short-term, fixed
income securities. However, to the extent that the Aggressive Growth Fund is so
invested, the Aggressive Growth Fund is not pursuing and may not achieve its
investment objective.
 
RISK FACTORS AND INVESTMENT TECHNIQUES
 
GENERAL. Like any investment program, an investment in any of the Funds entails
certain risks. As funds investing primarily in common stocks, each Fund is
subject to stock market risk, i.e., the possibility that stock prices in general
will decline over short or even extended periods.
 
Since the Funds, to different degrees, also invest or may invest in bonds,
investors in a Fund, to the extent so invested, are also exposed to bond market
risk, i.e., fluctuations in the market value of bonds. Bond prices are
influenced primarily by changes in the level of interest rates. When interest
rates rise, the prices of bonds generally fall; conversely, when interest rates
fall, bond prices generally rise. While bonds normally fluctuate less in price
than stock, there have been in the recent past extended periods of cyclical
increases in interest rates that have caused significant declines in bond
prices.
 
Current income by its nature always contributes positively to total return.
Therefore, the current income expected to be generated from an investment in the
Balanced Fund will counterbalance to some degree the adverse price fluctuations
of the securities held by the Balanced Fund. The effective result should
therefore be lower total return volatility for the Balanced Fund than a fund
which does not provide such current income.
 
                                       13
<PAGE>   44
 
The Aggressive Growth Fund is intended for investors who can accept the higher
risks involved in seeking potentially higher capital appreciation through
investments in growth oriented companies. A growth oriented company typically
invests most of its net income in its enterprise and does not pay out much, if
any, in dividends. Accordingly, the Aggressive Growth Fund does not anticipate
any significant distributions to shareholders from net investment income, and
potential investors should be in a financial position to forego current income
from their investment in the Aggressive Growth Fund. The securities of less
seasoned companies may have limited marketability and may be subject to more
abrupt or erratic market movements over time than securities of more seasoned
companies or the market as a whole.
 
The Balanced Fund may invest in certain variable or floating rate government
securities and, as described below, each Fund may invest in put and call options
and futures. Such instruments are considered to be "derivatives." A derivative
is generally defined as an instrument whose value is based upon, or derived
from, some underlying index, reference rate (e.g., interest rates), security,
commodity or other asset. No Fund will not invest more than 10% of its total
assets in any such derivatives at any one time.
 
REPURCHASE AGREEMENTS. Securities held by each Fund may be subject to repurchase
agreements. Under the terms of the repurchase agreement, a Fund would acquire
securities from a financial institution such as a well-established securities
dealer or a bank which is a member of the Federal Reserve System which the
Adviser deems creditworthy under guidelines approved by the Group's Board of
Trustees. At the time of purchase, the bank or securities dealer agrees to
repurchase the underlying securities from that Fund at a specified time and
price. The resale price reflects the purchase price plus an agreed upon market
rate of interest which is unrelated to the coupon rate or maturity of the
underlying security. A Fund will only enter into a repurchase agreement where
(i) the underlying securities are of the type which such Fund's investment
policies would allow it to purchase directly, (ii) the market value of the
underlying security, including interest accrued, will at all times be equal to
or exceed the value of the repurchase agreement, and (iii) payment for the
underlying securities is made only upon physical delivery or evidence of book-
entry transfer to the account of such Fund's custodian or a bank acting as
agent. The Adviser will be responsible for continuously monitoring such
requirements.
 
WHEN-ISSUED AND DELAYED-DELIVERY TRANSACTIONS. The Balanced Fund may also
purchase securities on a when-issued or delayed-delivery basis. The Balanced
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, although such transactions
represent a form of leveraging. 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. The Balanced Fund
will not pay for such securities or start earning interest on them until they
are received. When the Balanced Fund agrees to purchase such securities, its
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, the Balanced Fund relies on the seller to
complete the transaction; the seller's failure to do so may cause the Balanced
Fund to miss a price or yield considered to be advantageous.
 
   
The Balanced Fund's commitments to purchase when-issued securities will not
exceed 25% of the value of its total assets absent unusual market conditions. In
the event that its commitments to purchase when-issued securities ever exceed
25% of the value of its assets, the Balanced Fund's liquidity and the ability of
the Adviser to manage it might be adversely affected.
    
 
   
MEDIUM-GRADE SECURITIES. As described above, the Balanced Fund and the
Aggressive Growth Fund may each invest in securities within the fourth highest
rating group assigned by an NRSRO, (e.g. BBB or Baa by S&P and Moody's,
respectively) and comparable unrated securities. These types of debt securities
are considered by Moody's to have some speculative characteristics, and are more
vulnerable to changes in economic conditions, higher interest rates or adverse
issuer-specific developments which are more likely to lead to a weaker capacity
to make principal and interest payments than comparable higher rated debt
securities.
    
 
                                       14
<PAGE>   45
 
   
Should subsequent events cause the rating of a security purchased by the
Balanced Fund or the Aggressive Growth Fund to fall below BBB or Baa, as the
case may be, the Adviser will consider such an event in determining whether that
Fund should continue to hold that security. In no event, however, would such
Funds be required to liquidate any such portfolio security where the Fund would
suffer a loss on the sale of such security.
    
 
   
FOREIGN SECURITIES. Each Fund may also invest up to 25% of its net assets in
foreign securities through the purchase of sponsored and unsponsored American
Depositary Receipts ("ADRs"). ADRs are receipts typically issued by a United
States bank or trust company evidencing ownership of the underlying foreign
securities and are denominated in U.S. dollars. Institutions issuing ADRs may
not be sponsored by the issuer. Unsponsored ADRs may be less liquid than
sponsored ADRs, and there may be less information available regarding the
underlying foreign issuer for unsponsored ADRs since a non-sponsored institution
is not required to provide the same shareholder information that a sponsored
institution is required to provide under its contractual arrangements with the
issuer. Investment in foreign securities, including ADRs, is subject to special
investment 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 income, possible seizure, nationalization, or expropriation of foreign
investments or deposits, less stringent disclosure requirements, the possible
establishment of exchange controls or taxation at the source, or the adoption of
other foreign governmental restrictions. In addition, foreign issuers may be
subject to different accounting, auditing, reporting, and recordkeeping
standards than those applicable to U.S. domestic issuers, and securities markets
in foreign countries may be structured differently from and may not be as liquid
as the U.S. markets. A Fund will acquire securities issued by foreign issuers
only when the Adviser believes that the risks associated with such investments
are minimal.
    
 
   
RESTRICTED SECURITIES. Securities in which the Balanced Fund may invest include
securities issued by corporations without registration under the Securities Act
of 1933, as amended (the "1933 Act"), including securities issued in reliance on
the so-called "private placement" exemption from registration which is afforded
by Section 4(2) of the 1933 Act ("Section 4(2) securities"). Section 4(2)
securities are restricted as to disposition under the Federal securities laws,
and generally are sold to institutional investors such as the Balanced Fund who
agree that they are purchasing the securities for investment and not with a view
to public distribution. Any resale must also generally be made in an exempt
transaction. Section 4(2) securities are normally resold to other institutional
investors through or with the assistance of the issuer or investment dealers who
assist in the placement of such Section 4(2) securities, thus providing some
liquidity.
    
 
   
Pursuant to procedures adopted by the Board of Trustees of the Group, the
Adviser may determine Section 4(2) securities to be liquid if such securities
are eligible for resale under Rule 144A under the 1933 Act and are readily
saleable. Rule 144A permits the Balanced Fund to purchase securities which have
been privately placed and resell such securities to certain qualified
institutional buyers without restriction. For purposes of determining whether a
Rule 144A security is readily saleable, and therefore liquid, the Adviser must
consider, among other things, the frequency of trades and quotes for the
security, the number of dealers willing to purchase or sell the security and the
number of potential purchasers, dealer undertakings to make a market in the
security, and the nature of the security and marketplace trades of such
security. However, investing in Rule 144A securities, even if such securities
are initially determined to be liquid, could have the effect of increasing the
level of the Balanced Fund's illiquidity to the extent that qualified
institutional buyers become, for a time, uninterested in purchasing these
securities.
    
 
   
REITS. Each of the Funds may also invest in securities of equity real estate
investment trusts ("REITs"). REITs pool investors' funds for investment
primarily in commercial real estate properties. Investment in REITs may subject
a Fund to certain risks. REITs may be affected by changes in the value of the
underlying property owned by the trusts. REITs are dependent upon specialized
management skill, may not be diversified and are subject to the risks of
financing projects. REITs are also subject to heavy cash flow dependency,
defaults by borrowers, self liquidation and the possibility of failing to
qualify for the beneficial tax treatment available to REITs under the Internal
Revenue Code and to maintain its exemption from the
    
 
                                       15
<PAGE>   46
 
   
1940 Act. As a shareholder in a REIT, a Fund would bear, along with other
shareholders, its pro rata portion of the REIT's operating expenses. These
expenses would be in addition to the advisory and other expenses that the Fund
bears directly in connection with its own operations.
    
 
PUT AND CALL OPTIONS. Subject to its investment policies and for purposes of
hedging against market risks related to its portfolio securities, each Fund may
purchase put and call options on securities. Purchasing options is a specialized
investment technique that entails a substantial risk of a complete loss of the
amounts paid as premiums to writers of options. A Fund will purchase put options
only on securities in which the Fund may otherwise invest. Each Fund may also
engage in writing call options from time to time as the Adviser deems
appropriate. Each Fund will write only covered call options (options on
securities owned by that Fund). In order to close out a call option it has
written, a Fund will 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 has written. When a
portfolio security subject to a call option is sold, such Fund will effect a
closing purchase transaction to close out any existing call option on that
security. If the 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 market
conditions, it is not expected that the underlying value of portfolio securities
subject to such options would exceed 25% of the net assets of a Fund.
 
Each Fund, as part of its option transactions, also may purchase index put and
call options and write index options. As with options on individual securities,
a Fund will write only covered index call options. Through the writing or
purchase of index options a Fund can achieve many of the same objectives as
through the use of options on individual securities. Options on securities
indices are similar to options on a security except that, rather than the right
to take or make delivery of a security at a specified price, an option on a
securities index gives the holder the right to receive, upon exercise of the
option, an amount of cash if the closing level of the securities index upon
which the option is based is greater than, in the case of a call, or less than,
in the case of a put, the exercise price of the option.
 
Price movements in securities which a Fund owns or intends to purchase probably
will not correlate perfectly with movements in the level of an index and,
therefore, a Fund bears the risk of a loss on an index option that is not
completely offset by movements in the price of such securities. Because index
options are settled in cash, a call writer cannot determine the amount of its
settlement obligations in advance and, unlike call writing on specific
securities, cannot provide in advance for, or cover, its potential settlement
obligations by acquiring and holding the underlying securities. A Fund may be
required to segregate assets or provide an initial margin to cover index options
that would require it to pay cash upon exercise.
 
FUTURES CONTRACTS. Each Fund may also enter into contracts for the future
delivery of securities and futures contracts based on a specific security, class
of securities or an index, purchase or sell options on any such futures
contracts and engage in related closing transactions. A futures contract on a
securities index is an agreement obligating either party to pay, and entitling
the other party to receive, while the contract is outstanding, cash payments
based on the level of a specified securities index.
 
Each Fund may engage in such futures contracts in an effort to hedge against
market risks. For example, when interest rates are expected to rise or market
values of portfolio securities are expected to fall, a Fund can seek through the
sale of futures contracts to offset a decline in the value of its portfolio
securities. When interest rates are expected to fall or market values are
expected to rise, a Fund, through the purchase of such contracts, can attempt to
secure better rates or prices for such Fund than might later be available in the
market when it effects anticipated purchases.
 
The acquisition of put and call options on futures contracts will, respectively,
give a Fund the right (but not the obligation), for a specified price, to sell
or to purchase the underlying futures contract, upon exercise of the option, at
any time during the option period.
 
Aggregate initial margin deposits for futures contracts, and premiums paid for
related options, may not exceed five percent of a Fund's total assets, and the
value of securities that are the subject of such futures and options (both for
receipt and delivery) may not exceed one-third of the market value of a Fund's
total
 
                                       16
<PAGE>   47
 
assets. Futures transactions will be limited to the extent necessary to maintain
each Fund's qualification as a regulated investment company.
 
Futures transactions involve brokerage costs and require a Fund to segregate
assets to cover contracts that would require it to purchase securities. A Fund
may lose the expected benefit of futures transactions if interest rates or
securities prices move in an unanticipated manner. Such unanticipated changes
may also result in poorer overall performance than if the Fund had not entered
into any futures transactions. In addition, the value of a Fund's futures
positions may not prove to be perfectly or even highly correlated with the value
of its portfolio securities, limiting such Fund's ability to hedge effectively
against interest rate and/or market risk and giving rise to additional risks.
There is no assurance of liquidity in the secondary market for purposes of
closing out futures positions.
 
INVESTMENT COMPANY SECURITIES. Each Fund may also invest up to 10% of the value
of its total assets in the securities of other investment companies subject to
the limitations set forth in the 1940 Act. Each Fund intends to invest in the
securities of other investment companies which, in the opinion of the Adviser,
will assist such Fund in achieving its objectives and in money market mutual
funds for purposes of short-term cash management. A Fund's investment in such
other investment companies may result in the duplication of fees and expenses,
particularly investment advisory fees. For a further discussion of the
limitations on each Fund's investments in other investment companies, see
"INVESTMENT OBJECTIVES AND POLICIES -- Additional Information on Portfolio
Instruments -- Securities of Other Investment Companies" in the Group's
Statement of Additional Information.
 
INVESTMENT RESTRICTIONS
 
Each 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 that Fund (as defined
below under "WHAT ARE MY RIGHTS AS A SHAREHOLDER?").
 
Each 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, more than 5% of the value of the
        Fund's total assets would be invested in such issuer, or the Fund would
        hold more than 10% of the outstanding voting securities of the issuer,
        except that up to 25% of the value of the Fund's total assets may be
        invested without regard to such limitations. There is no limit to the
        percentage of assets that may be invested in U.S. Treasury bills, notes,
        or other obligations issued or guaranteed by the U.S. Government or its
        agencies or instrumentalities.
 
     2. 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) 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.
 
     3. Borrow money or issue senior securities, except that the Fund may borrow
        from banks or enter into reverse repurchase agreements or dollar roll
        agreements for temporary purposes in amounts up to 10% of the value of
        its total assets at the time of such borrowing and except as permitted
        pursuant to an exemption from the 1940 Act. The Fund will not purchase
        securities while its borrowings (including reverse repurchase agreements
        and dollar roll agreements) exceed 5% of its total assets.
 
     4. Make loans, except that the Fund may purchase or hold debt instruments
        and lend portfolio securities in accordance with its investment
        objectives and policies, make time deposits with financial institutions
        and enter into repurchase agreements.
 
                                       17
<PAGE>   48
The following additional investment restriction may be changed without the vote
of a majority of the outstanding Shares of a Fund.
 
Each Fund will not:
 
     1. Purchase or otherwise acquire any securities, if as a result, more than
        15% of the Fund's net assets would be invested in securities that are
        illiquid.
 
- --------------------------------------------------------------------------------
HOW DO I PURCHASE INVESTOR SHARES OF THE FUNDS?
- --------------------------------------------------------------------------------
 
GENERAL

   
Each Fund's Investor Shares may be purchased at the public offering price, as
described below under "Public Offering Price," through The Ohio Company,
principal underwriter of the Funds' Shares, at its address and telephone number
set forth on the cover page of this Prospectus, and through other broker-dealers
who are members of the National Association of Securities Dealers, Inc. and have
sales agreements with The Ohio Company.
    
 
Subsequent purchases of Investor Shares of a Fund may be made by ACH processing
as described under "WHAT OTHER SHAREHOLDER PROGRAMS ARE PROVIDED? -- ACH
Processing" below. In addition, if an Account Information Form has previously
been received by The Ohio Company, Investor Shares may also be purchased by
wiring funds to the Funds' custodian. Prior to wiring any such funds and in
order to ensure that wire orders are invested properly, you must call The Ohio
Company to obtain the necessary instructions and information.
 
The minimum initial investment for individuals is $1,000, except the initial
investment for an applicant investing by means of the Automatic Investment Plan,
as described below, must be at least $50. Subsequent investments must be in
amounts of at least $50.
 
The Group reserves the right to reject any order for the purchase of Investor
Shares in whole or in part. You will receive a confirmation of each new
transaction in your account, which will also show the total number of Investor
Shares owned by you and the number of Investor Shares being held in safekeeping
by Cardinal Management Corp., as the Funds' transfer agent (the "Transfer
Agent"), for your account. Certificates representing Investor Shares will not be
issued.
 
PUBLIC OFFERING PRICE
 
The public offering price of Investor Shares of each Fund is the net asset value
per share (see "HOW IS NET ASSET VALUE CALCULATED?") next determined after
receipt by The Ohio Company, its agents or broker-dealers with whom it has an
agreement, of an order and payment, plus a sales charge as follows:

<PAGE>   49
 
The above charges on investments of $100,000 or more are applicable to purchases
made at one time by an individual, or an individual, his spouse and their
children not of legal age, or a trustee, guardian or other like fiduciary of
certain single trust estates or certain single fiduciary accounts.
 
   
No sales charge is imposed on purchases of Shares by (1) officers, trustees, and
employees of the Group, or (2) full-time employees of The Ohio Company or the
Adviser who have been such for at least 90 days or by qualified retirement plans
for such persons. The Ohio Company may change or eliminate the foregoing waivers
at any time. The Ohio Company may also periodically waive all or a portion of
the sales charge for all investors with respect to a Fund.
    
 
From time to time, The Ohio Company, from its own resources, may also provide
additional compensation to securities dealers in connection with sales of shares
of the Cardinal Funds. Such compensation will include financial assistance to
securities dealers in connection with conferences, sales or training programs
for their employees, seminars for the public, advertising, sales campaigns
and/or shareholder services and programs regarding one or more of the Cardinal
Funds and other dealer-sponsored programs or events. In some instances, this
compensation may be made available only to certain securities dealers whose
representatives have sold or are expected to sell significant amounts of shares
of the Cardinal Funds. Compensation will 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. Securities
dealers may not use sales of a Fund's Shares to qualify for this compensation to
the extent such may be prohibited by the laws of any state or any
self-regulatory agency, such as the National Association of Securities Dealers,
Inc. In addition, The Ohio Company may make ongoing payments to brokerage firms,
financial institutions (including banks) and others to facilitate the
administration and servicing of shareholder accounts. None of the aforementioned
additional compensation is paid for by any Fund or its shareholders.
 
AUTOMATIC INVESTMENT PLAN
 
The Funds have made arrangements to enable you to make automatic monthly or
quarterly investments, in the minimum amount of $50 per transaction, from your
checking account. Assuming the cooperation of your financial institution, your
checking account therein will be debited to purchase Investor Shares of the Fund
specified by you on the periodic basis you select. Confirmation of your purchase
of such Fund's Investor Shares will be provided by the Transfer Agent. The debit
of your checking account will be reflected in the checking account statement you
receive from your financial institution. Please contact The Ohio Company for the
appropriate form.
 
- --------------------------------------------------------------------------------
HOW MAY I QUALIFY FOR QUANTITY DISCOUNTS?
- --------------------------------------------------------------------------------
 
LETTER OF INTENTION
 
If you (including your spouse and children not of legal age) intend to purchase
$100,000 or more of Investor Shares of a Fund and of Investor Shares of any
other Cardinal Fund sold with a sales charge (a "Cardinal Load Fund") during any
13-month period you may sign a letter of intention to that effect obtained from
The Ohio Company and pay the reduced sales charge applicable to the total amount
of Investor Shares to be so purchased. The 13-month period during which the
Letter of Intention is in effect will begin on the date of the earliest purchase
to be included. In addition, trustees, guardians or other like fiduciaries of
single trust estates or certain single fiduciary accounts may take advantage of
the quantity discounts pursuant to a letter of intention.
 
A letter of intention is not a binding obligation upon you to purchase the full
amount indicated. Investor Shares purchased with the first 5% of such amount
will be held in escrow (while remaining registered in your name) to secure
payment of the higher sales charge applicable to the Investor Shares actually
purchased. If the full amount indicated is not purchased, such escrowed Investor
Shares will be involuntarily redeemed to pay the additional sales charge, if
necessary. Dividends on escrowed Investor Shares,

 
                                       19
<PAGE>   50
whether paid in cash or reinvested in additional Investor Shares of the
applicable Cardinal Load Fund, are not subject to escrow. The escrowed Investor
Shares will not be available for disposal by you until all purchases pursuant to
the Letter of Intention have been made or the higher sales charge has been paid.
When the full amount indicated has been purchased, the escrow will be released.
To the extent that you purchase more than the dollar amount indicated on the
Letter of Intention and qualify for a further reduced sales charge, the sales
charge will be adjusted for the entire amount purchased at the end of the
13-month period. The difference in sales charge will be, as you instruct, either
delivered to you in cash or used to purchase additional Investor Shares of the
Cardinal Load Fund designated by you subject to the rate of sales charge
applicable to the actual amount of the aggregate purchases. This program,
however, may be modified or eliminated at any time or from time to time by the
Group without notice.
 
CONCURRENT PURCHASES
 
For purposes of qualifying for a lower sales charge, you have the privilege of
combining "concurrent purchases" of Investor Shares of a Fund and of one or more
of the other Cardinal Load Funds. For example, if you concurrently purchase
Investor Shares of the Balanced Fund at the total public offering price of
$50,000 and Investor Shares of another Cardinal Load Fund at the total public
offering price of $50,000, the sales charge paid by you would be that applicable
to a $100,000 purchase as shown in the table above. "Concurrent purchases," as
described above, shall include the combined purchases of Investor Shares of you,
your spouse and your children not of legal age. To receive the applicable public
offering price pursuant to this privilege, you must, at the time of purchase,
give The Ohio Company sufficient information to permit confirmation of
qualification. This privilege, however, may be modified or eliminated at any
time or from time to time by the Group without notice thereof.
 
RIGHTS OF ACCUMULATION
 
After your initial purchase of Investor Shares you may also be eligible to pay a
reduced sales charge for your subsequent purchases of Investor Shares where the
total public offering price of Investor Shares then being purchased plus the
then aggregate current net asset value of Investor Shares of such Fund and of
Investor Shares of any Cardinal Load Fund held in your account equals $100,000
or more. You would be able to purchase Investor Shares at the public offering
price applicable to the total of (a) the total public offering price of the
Investor Shares of the Fund then being purchased plus (b) the then current net
asset value of Investor Shares of such Fund and of Investor Shares of any other
Cardinal Load Fund held in your account. For purposes of determining the
aggregate current net asset value of Investor Shares held in your account, you
may include Investor Shares then owned by your spouse and children not of legal
age.
 
You may obtain additional information about the foregoing special purchase
method from The Ohio Company. You are responsible for notifying The Ohio Company
at the time of purchase when purchases may be accumulated to take advantage of
the reduced sales charge. This program, however, may be modified or eliminated
at any time or from time to time by the Group without notice thereof.
 
- --------------------------------------------------------------------------------
WHAT DISTRIBUTIONS WILL I RECEIVE?
- --------------------------------------------------------------------------------
 
Dividends and distributions shall be made with such frequency (long term capital
gains normally will be distributed only once annually) and in such amounts as
the Group from time to time shall determine and shall be paid from net income
and net realized capital gains of the Funds. It is the policy of each Fund to
distribute, at least annually, substantially all of its net investment income
and to distribute annually any net realized capital gains. Unless a shareholder
specifically requests otherwise in writing to the Transfer Agent, dividends and
distributions will be made only in additional full and fractional Investor
Shares of a Fund and not in cash. Dividends are paid in cash not later than
seven days after a shareholder's complete redemption of his Investor Shares in a
Fund.
 
Each Fund's net investment income available for distribution to the holders of
Investor Shares will be reduced by the amount of Rule 12b-1 fees paid out under
the Plan described below.

 
                                       20
<PAGE>   51
 
Shareholders may also elect to receive dividends and distributions in cash by
using ACH processing as described under "WHAT OTHER SHAREHOLDER PROGRAMS ARE
PROVIDED? -- ACH Processing" below.
 
- --------------------------------------------------------------------------------
HOW MAY I REDEEM MY INVESTOR SHARES?
- --------------------------------------------------------------------------------
 
Investors may redeem Investor Shares of a Fund on any Business Day at the net
asset value per Investor Share next determined following receipt by the Transfer
Agent, 215 East Capital Street, Columbus, Ohio 43215, of written or telephonic
notice to redeem, as described more fully below. See "HOW IS NET ASSET VALUE
CALCULATED?", below, for a description of when net asset value is determined.
 
As requested, The Ohio Company, on behalf of a shareholder, will forward the
foregoing notice to redeem to the Transfer Agent without charge. Other
broker-dealers may assist a shareholder in redeeming his Investor Shares and may
charge a fee for such services.
 
The Group will make payment for redeemed Investor Shares as promptly as
practicable but in no event more than seven days after receipt by the Transfer
Agent of the foregoing notice. The Group reserves the right to delay payment for
the redemption of Investor Shares where such Investor Shares were purchased with
other than immediately available funds, but only until the purchase payment has
cleared (which may take fifteen or more days from the date the purchase payment
is received by the applicable Fund). The purchase of Investor Shares by wire
transfer of federal funds would avoid any such delay.
 
The Group intends to pay cash for all Investor Shares redeemed, but, under
abnormal conditions which make payment in cash unwise, the Group may make
payment wholly or partly in readily marketable portfolio securities at their
then market value equal to the redemption price. In such cases, an investor may
incur brokerage costs in converting such securities to cash.

The Group may suspend the right of redemption or may delay payment during any
period the determination of net asset value is suspended. See "HOW IS NET ASSET
VALUE CALCULATED?".
 
Due to the high cost of maintaining accounts, the Group reserves the right to
redeem, at net asset value, involuntarily Shares in any account at the then
current net asset value if at any time redemptions (but not as a result of a
decrease in the market price of such Shares or the deduction of any sales
charge) have reduced a shareholder's total investment in a Fund to a net asset
value below $500. A shareholder will be notified in writing that the value of
Fund Shares in the account is less than $500 and allowed not less than 30 days
to increase his investment in such Fund to $500 before the redemption is
processed. Proceeds of redemptions so processed, including dividends declared to
the date of redemption, will be promptly paid to the shareholder.
 
REDEMPTION BY MAIL
 
Shareholders may redeem Investor Shares of a Fund by submitting a written
request therefor to the Transfer Agent, at 215 East Capital Street, Columbus,
Ohio 43215. The Transfer Agent will request a signature guarantee by an eligible
guarantor institution as described below. However, a signature guarantee will
not be required if (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, provided, however, that the address of record has not been
changed within the preceding 15 days. For purposes of this policy, an "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 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 or (2) it has reason
to believe that the transaction would otherwise be improper.

 
                                       21
<PAGE>   52
 
REDEMPTION BY TELEPHONE
 
Shareholders may redeem Investor Shares of a Fund by calling the Group at the
telephone number set forth on the front of this Prospectus. The shareholder may
direct that the redemption proceeds be mailed to the address of record.
 
Neither the Group, the Funds nor their service providers will be liable for any
loss, damages, expense or cost arising out of any telephone redemption effected
in accordance with the Group's telephone redemption procedures, acting upon
instructions reasonably believed to be genuine. The Group will employ procedures
designed to provide reasonable assurances that instructions by telephone are
genuine; if these procedures are not followed, the Group, the Funds or their
service providers may be liable for any losses due to unauthorized or fraudulent
instructions. These procedures may include recording all phone conversations,
sending confirmations to shareholders within 72 hours of the telephone
transaction, and verification of account name and account number or tax
identification number. If, due to temporary adverse conditions, investors are
unable to effect telephone transactions, shareholders may also redeem their
Investor Shares by mail as described above.
 
AUTOMATIC WITHDRAWAL
 
Shareholders may elect to have the proceeds from redemptions of Investor Shares
transmitted to an authorized bank account at a Federal Reserve member bank
through ACH processing as described under "WHAT OTHER SHAREHOLDER PROGRAMS ARE
PROVIDED? -- ACH Processing" below.
 
SYSTEMATIC WITHDRAWAL PLAN
 
If you are the owner of Investor Shares of a Fund having a total value of
$10,000 or more at the current net asset value, you may elect to redeem your
Investor Shares monthly or quarterly in amounts of $50 or more, pursuant to the
Group's Systematic Withdrawal Plan. Please contact The Ohio Company for the
appropriate form. Purchase of additional Investor Shares, using the Automatic
Investment Plan described above, concurrent with withdrawals may be
disadvantageous to certain shareholders because of tax liabilities and sales
charges.
 
- --------------------------------------------------------------------------------
WHAT OTHER SHAREHOLDER PROGRAMS ARE PROVIDED?
- --------------------------------------------------------------------------------
 
ACH PROCESSING
 
The Group offers ACH privileges. Investors may use ACH processing to make
subsequent purchases, redeem Shares and/or electronically transfer distributions
paid on Shares, in addition to the other methods described in this Prospectus.
ACH provides a method by which funds may be automatically transferred to or from
an authorized bank account at a Federal Reserve member bank that is an ACH
member. Please contact your representative if you are interested in ACH
processing.
 
EXCHANGE PRIVILEGE
 
   
Holders of Investor Shares of a Fund may, provided the amount to be exchanged
meets the applicable minimum investment requirements and the exchange is made in
states where it is legally authorized, exchange at respective net asset values,
Investor Shares of any Fund for Investor Shares of another Fund (upon the
payment of the appropriate sales charge) or for:
    
 
   
    Investor Shares of
     Cardinal Government Obligations Fund,
     a fund investing in securities issued
     or guaranteed by the U.S. Government
     (upon the payment of the appropriate
     sales charge);
    
 
                                       22
<PAGE>   53
 
   
    Shares of Cardinal Government Securities Money Market Fund,
     a U.S. Government securities money market fund
     (without payment of any sales charge); or
    
 
   
    Shares of Cardinal Tax Exempt Money Market Fund,
     a tax-free money market fund
     (without payment of any sales charge).
    
 
   
Notwithstanding the foregoing and subject to the limitations contained in the
following paragraph, (i) exchanges by holders of Investor Shares, for whom the
sales charge has been waived, for Investor Shares of a Cardinal Load Fund may be
completed without the payment of a sales charge, and (ii) exchanges of Investor
Shares by all other shareholders for Investor Shares of a Cardinal Load Fund may
be completed upon the payment of a sales charge equal to the difference, if any,
between the sales charge payable upon purchase of Investor Shares of such
Cardinal Load Fund and the sales charge previously paid on the Investor Shares
to be exchanged.
    
 
   
The foregoing exchange privilege must be made by written or telephonic
authorization. A shareholder should notify The Ohio Company of his desire to
make an exchange, and The Ohio Company will furnish, as necessary, a prospectus
and an application form to open the account. The Transfer Agent will require
that any written authorization of an exchange include a signature guarantee as
described above under "HOW MAY I REDEEM MY SHARES? -- Redemption by mail."
However, a signature guarantee will not be required if the exchange requested is
within the same account or into an existing account of the shareholder held in
the same name or names and in the same capacity as the account from which the
exchange is to be made. Shareholders may also authorize an exchange of Shares of
a Fund by telephone. Neither the Group, the Funds nor any of their service
providers will be liable for any loss, damages, expense or cost arising out of
any telephone exchange authorization to the extent and subject to the
requirements set forth under "HOW MAY I REDEEM MY SHARES? -- Redemption by
telephone" above.
    
 
For tax purposes, an exchange is treated as a redemption and a new purchase.
However, a shareholder may not include any sales charge on Investor Shares of a
Fund for purposes of calculating the gain or loss realized upon an exchange of
those Investor Shares within 90 days of their purchase.
 
The Group may, at any time, modify or terminate the foregoing exchange
privilege. The Group, however, will give shareholders of the Funds 60 days'
advance written notice of any such modification or termination.
 
- --------------------------------------------------------------------------------
HOW IS NET ASSET VALUE CALCULATED?
- --------------------------------------------------------------------------------
 
The net asset value of each Fund is determined once daily as of 4:00 P.M.
Eastern Time, on each Business Day. A "Business Day" is a day on which the New
York Stock Exchange is open for business and any other day (other than a day on
which no Shares of such Fund are tendered for redemption and no order to
purchase any Shares of that Fund is received) during which there is a sufficient
degree of trading in a Fund's portfolio securities that the net asset value
might be materially affected by changes in the value of the portfolio
securities. The net asset value per share of each class of shares of a Fund is
computed by dividing the sum of the value of that Fund's portfolio securities
plus any cash and other assets (including interest and dividends accrued but not
received) allocable to such class minus all liabilities (including estimated
accrued expenses) allocable to such class by the total number of Shares of that
class of such Fund then outstanding.
 
The net asset value per share will fluctuate as the value of the investment
portfolio of a Fund changes.
 
Portfolio securities which are traded on United States stock exchanges are
valued at the last sale price on such an exchange as of the time of valuation on
the day the securities are being valued. Securities traded in the
over-the-counter market are valued at either the mean between the bid and ask
prices or the last sale price as one or the other may be quoted by the National
Association of Securities Dealers Automated Quotation System ("NASDAQ") as of
the time of valuation on the day the securities are being valued. The
 
                                       23
<PAGE>   54
 
Group uses one or more pricing services to provide such market quotations.
Securities and other assets for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
direction of the Board of Trustees of the Group.
 
Determination of the net asset value may be suspended at times when (a) trading
on the New York Stock Exchange is restricted by applicable rules and regulations
of the Commission, (b) the New York Stock Exchange is closed for other than
customary weekend and holiday closings, (c) an emergency exists as a result of
which disposal by the Group of portfolio securities owned by the Fund or
valuation of net assets of the Fund is not reasonably practicable, or (d) the
Commission has by order permitted such suspension.
 
- --------------------------------------------------------------------------------
DO THE FUNDS PAY FEDERAL INCOME TAX?
- --------------------------------------------------------------------------------
 
Each of the funds of the Group, including the Funds, is treated as a separate
entity for federal income tax purposes and intends to qualify as a "regulated
investment company" under the Code for so long as such qualification is in the
best interest of that fund's shareholders. Qualification as a regulated
investment company under the Code requires, among other things, that the
regulated investment company distribute to its shareholders at least 90% of its
investment company taxable income. Each Fund contemplates declaring as dividends
100% of such Fund's investment company taxable income (before deduction of
dividends paid).
 
A non-deductible 4% excise tax is imposed on regulated investment companies that
do not distribute in each calendar year(regardless of whether they otherwise
have a non-calendar taxable year) an amount equal to 98% of their ordinary
income for the calendar year plus 98% of their capital gain net income for the
one-year period ending on October 31 of such calendar year. The balance of such
income must be distributed during the next calendar year. If distributions
during a calendar year were less than the required amount, the Fund would be
subject to a nondeductible excise tax equal to 4% of the deficiency.
 
- --------------------------------------------------------------------------------
WHAT ABOUT MY TAXES?
- --------------------------------------------------------------------------------
 
It is expected that each Fund will distribute annually to shareholders all or
substantially all of that Fund's net ordinary income and net realized capital
gains and that such distributed net ordinary income and distributed net realized
capital gains will be taxable income to shareholders for federal income tax
purposes, even if paid in additional Shares of the Fund and not in cash. The
dividends received deduction for corporations will apply to the aggregate of
such ordinary income distributions in the same proportion as the aggregate
dividends eligible for the dividends received deduction, if any, received by a
Fund bear to its gross income.
 
Distribution by a Fund of the excess of net long-term capital gain over net
short-term capital loss is taxable to shareholders as long-term capital gain in
the year in which it is received, regardless of how long the shareholder has
held the Shares. Such distributions are not eligible for the dividends received
deduction.
 
If the net asset value of a Share is reduced below the shareholder's cost of
that Share by the distribution of income or gain realized on the sale of
securities, the distribution is a return of invested principal, although taxable
as described above.
 
Prior to purchasing Shares, the impact of dividends or capital gains
distributions which are expected to be declared or have been declared, but have
not been paid, should be carefully considered. Any such dividends or capital
gains distributions paid shortly after a purchase of Shares prior to the record
date will have the effect of reducing the per share net asset value of the
Shares by the amount of the dividends or distributions. All or a portion of such
dividends or distributions, although in effect a return of capital, is subject
to tax.
 
Foreign taxes may be imposed on a Fund by foreign countries with respect to its
income from foreign securities. Since less than 50% in value of each Fund's
total assets at the end of its fiscal year are expected to be invested in
securities of foreign corporations, no Fund will be entitled under the Code to
pass through

 
                                       24
<PAGE>   55
 
to its shareholders their pro rata share of the foreign taxes paid by such Fund.
These taxes will be taken as a deduction by that Fund.
 
The foregoing is intended only as a brief summary of some of the important tax
considerations generally affecting the Funds and their shareholders. Potential
investors in the Funds are urged to consult their tax advisers concerning the
application of federal, state and local taxes as such laws and regulations
affect their own tax situation.
 
The Transfer Agent will inform shareholders at least annually of the amount and
nature of such income and capital gains.

WHO MANAGES MY INVESTMENT IN THE FUNDS?
- --------------------------------------------------------------------------------
 
   
Except where shareholder action is required by law, all of the authority of the
Group is exercised under the direction of the Group's Trustees. Unless so
required by the Group's Declaration of Trust or By-Laws or by Ohio law, at any
given time all of the Trustees may not have been elected by the shareholders of
the Group. The Trustees are empowered to elect officers and contract with and
provide for the compensation of agents, consultants and other professionals to
assist and advise in its day-to-day operations. The Group will be managed in
accordance with its Declaration of Trust and the laws of Ohio governing business
trusts.
    
 
   
The Trustees of the Group 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 the Adviser or The Ohio Company receives any compensation
from the Group for acting as a Trustee of the Group. The officers of the Group
receive no compensation directly from the Group for performing the duties of
their offices. The Adviser receives fees from the Group for acting as investment
adviser and manager and as dividend and transfer agent and for providing certain
fund accounting services. The Ohio Company receives no fees under its
Distribution Agreement with the Group but, with respect to Investor Shares only,
may retain all or a portion of the sales charge and receives fees under the
Distribution Plan discussed below.
    
 
INVESTMENT ADVISER AND MANAGER
 
Cardinal Management Corp. (the "Adviser"), 155 East Broad Street, Columbus, Ohio
43215, a wholly owned subsidiary of The Ohio Company, is the investment adviser
and manager of each of the Funds. The Adviser is also the investment adviser and
manager of each of the other Cardinal Funds.
 
   
The Ohio Company, an investment banking firm organized in 1925, is a member of
the New York and Chicago Stock Exchanges, other regional stock exchanges and the
National Association of Securities Dealers, Inc. Descendants of H.P. and R.F.
Wolfe, deceased, and members of their families, through their possession of a
majority of voting stock, may be considered controlling persons of The Ohio
Company. The Ohio Company serves as the principal underwriter for each of the
Cardinal Funds.
    
 
   
In its capacity as investment adviser, and subject to the ultimate authority of
the Group's Board of Trustees, the Adviser, in accordance with the Funds'
investment objectives and policies, manages each Fund, and makes decisions with
respect to and places orders for all purchases and sales of its portfolio
securities. Since the Reorganization with respect to The Cardinal Fund and since
December 22, 1995, with respect to TCFI, The Cardinal Fund's predecessor, John
Bevilacqua has been primarily responsible for the day-to-day management of the
portfolio of such Funds. Mr. Bevilacqua has been a Vice President and Portfolio
Manager for The Ohio Company since October, 1994. Prior thereto, and since
February, 1984, Mr. Bevilacqua served as Second Vice President -- Investments
for Midland Mutual Life Insurance Company, Columbus, Ohio. Since October 1,
1996, David C. Will and Joseph A. Miner have been responsible jointly for the
day-to-day management of the Balanced Fund's portfolio. Mr. Will has been a Vice
President of the Adviser and The Ohio Company since 1990 and has more than 25
years of investment management experience. Mr. Miner has been a Vice President
and Senior Portfolio Manager of the Adviser and/or The Ohio Company since
August, 1995. Prior thereto and since 1992, Mr. Miner was a Vice President and
Portfolio Manager with Key Trust Company of Ohio. From 1987 to 1992, Mr. Miner
was an investment
    
 
                                       25
<PAGE>   56
 
   
strategist and an Assistant Vice President of Citizens Fidelity Capital
Management Company, Louisville, Kentucky. Since August 12, 1996, Mr. Harold C.
Elliott has been primarily responsible for the day-to-day management of the
Aggressive Growth Fund's portfolio. Mr. Elliott has been a Vice President and
Chief Investment Officer of The Ohio Company since March 1996. Prior thereto,
from May, 1993 to March 1996, Mr. Elliott was Vice President and Chief
Investment Officer of The Bank of Tokyo Trust Company (New York City), a
wholly-owned subsidiary of The Bank of Tokyo Limited, Tokyo, Japan. Prior
thereto, from December, 1994 to May, 1993, Mr. Elliott was employed by First
Fidelity Bank, Philadelphia, Pennsylvania.
    
 
In addition, pursuant to the Investment Advisory Agreement, the Adviser
generally assists in all aspects of each Fund's administration and operation.
 
For the services provided and expenses assumed pursuant to its investment
advisory agreement with the Group with respect to the Funds, the Adviser
receives a fee from the Funds, computed daily and paid monthly at the following
annual rates: with respect to The Cardinal Fund, 0.60% of such Fund's average
daily net assets; and with respect to both the Balanced Fund and the Aggressive
Growth Fund, 0.75% of such Funds' average daily net assets. While in the opinion
of the staff of the Commission such fees with respect to the Balanced Fund and
the Aggressive Growth Fund are higher than the advisory fee paid by most mutual
funds, the Group's Board of Trustees believes them to be comparable to advisory
fees paid by many funds having similar objectives and policies.
 
The Adviser may periodically waive all or a portion of its advisory fee with
respect to a Fund to increase the net income of such Fund available for
distribution as dividends. The waiver of such fee will cause the return and/or
yield of such Fund to be higher than it would otherwise be in the absence of
such a waiver.
 
DIVIDEND AND TRANSFER AGENT AND FUND ACCOUNTANT
 
The Group has entered into a Transfer Agency and Fund Accounting Agreement with
Cardinal Management Corp. (the "Transfer Agent"), 215 East Capital Street,
Columbus, Ohio 43215, pursuant to which the Transfer Agent has agreed to act as
the Funds' transfer agent and dividend disbursing agent. In consideration of
such services, each Fund has agreed to pay the Transfer Agent an annual fee,
paid monthly, equal to $18 per shareholder account plus out-of-pocket expenses.
In addition, the Transfer Agent provides certain fund accounting services for
the Funds. The Transfer Agent receives a fee from each Fund for such services
equal to a fee computed daily and paid periodically at an annual rate of .03% of
that Fund's average daily net assets of up to $100 million and .01% of such
Fund's average daily net assets in excess of $100 million.
 
DISTRIBUTOR
 
The Group has entered into a Distributor's Contract with The Ohio Company, 155
East Broad Street, Columbus, Ohio 43215, pursuant to which Shares of the Funds
will be offered continuously on a best efforts basis by The Ohio Company and
dealers selected by The Ohio Company. H. Keith Allen is an officer and trustee
of the Group and an officer and director of The Ohio Company. Frank W. Siegel is
an officer and trustee of the Group and an officer of The Ohio Company. James M.
Schrack II is an officer of both the Group and The Ohio Company.
 
EXPENSES
 
   
The Adviser bears all expenses in connection with the performance of its
services as investment adviser, manager, transfer agent and fund accountant
other than the cost of securities (including brokerage commissions, if any)
purchased for the Funds. The Trustees reserve the right to allocate certain
other expenses, which can reasonably be identified as relating to a particular
class, solely to such class, including Investor Shares, as they deem appropriate
("Class Expenses"). Such expenses include (a) transfer agency fees identified as
being attributable to a specific class; (b) printing and postage expenses
related to preparing and distributing materials such as shareholder reports,
prospectuses and proxy statements to current shareholders of a specific class;
(c) Blue Sky registration fees incurred by a class of shares; (d) SEC
    
 
                                       26
<PAGE>   57
 
   
registration fees incurred by a class; (e) expenses of administrative personnel
and services as required to support the shareholders of a specific class; (f)
litigation or other legal expenses and audit or other accounting expenses
relating solely to one class; (g) trustees' fees or expenses incurred as a
result of issues relating to one class; and (h) shareholder meeting costs that
relate to a specific class.
    
 
DISTRIBUTION PLAN
 
   
Pursuant to Rule 12b-1 under the 1940 Act, the Group has adopted a Distribution
and Shareholder Service Plan with respect to its Investor Shares (the "Plan"),
under which each Fund is authorized to pay The Ohio Company, as such Fund's
principal underwriter, a periodic amount calculated at an annual rate not to
exceed twenty-five one-hundredths of one percent (.25%) of the average daily net
asset value of the Investor Shares of that Fund. Such amount may be used by The
Ohio Company to pay broker-dealers (including The Ohio Company), banks and other
institutions (a "Participating Organization") for distribution and/or
shareholder service assistance pursuant to an agreement between The Ohio Company
and the Participating Organization or for distribution assistance and/or
shareholder service provided by The Ohio Company pursuant to an agreement
between The Ohio Company and the Group. Under the Plan, a Participating
Organization may include The Ohio Company, its subsidiaries, and its affiliates.
The Ohio Company may from time to time waive all or a portion of the fees
payable to it pursuant to the Plan. Any such waiver will cause the total return
and yield of the Investor Shares of a Fund to be higher than they would
otherwise be absent such a waiver.
    
 
   
As authorized by the Plan, The Ohio Company has entered into a Rule 12b-1
Agreement with the Group pursuant to which The Ohio Company has agreed to
provide certain shareholder services in connection with Investor Shares of the
Funds purchased and held by The Ohio Company for the accounts of its customers
and Investor Shares of the Funds purchased and held by customers of The Ohio
Company directly, including, but not limited to, answering shareholder questions
concerning the Funds, providing information to shareholders on their investments
in Investor Shares of a Fund and providing such personnel and communication
equipment as is necessary and appropriate to accomplish such matters. In
consideration of such services the Group has agreed to pay The Ohio Company a
monthly fee, computed at the annual rate of .25% of the average aggregate net
asset value of Investor Shares held during the period in customer accounts for
which The Ohio Company has provided services under this Agreement. Such fees
paid by the Group will be borne solely by the Investor Shares of the applicable
Fund. Such fee may exceed the actual costs incurred by The Ohio Company in
providing such services.
    
 
In addition, The Ohio Company may enter into, from time to time, other Rule
12b-1 Agreements with selected dealers pursuant to which such dealers will
provide certain shareholder services such as those described above.
 
CUSTODIAN
 
The Group has appointed The Fifth Third Bank ("Fifth Third"), 38 Fountain Square
Plaza, Cincinnati, Ohio 45263, as the Funds' custodian. In such capacity, Fifth
Third will hold or arrange for the holding of all portfolio securities and other
assets acquired and owned by the Funds.
 
- --------------------------------------------------------------------------------
WHAT ARE MY RIGHTS AS A SHAREHOLDER?
- --------------------------------------------------------------------------------
 
   
The Group was organized as an Ohio business trust on March 23, 1993. The Group
currently consists of six funds. The shares of each of the funds of the Group,
other than the two money market funds, Cardinal Government Securities Money
Market Fund ("CGSMMF") and Cardinal Tax Exempt Money Market Fund ("CTEMMF"), are
currently offered in two separate classes: Investor A Shares, otherwise referred
to as Investor Shares, and Investor Y Shares, otherwise referred to as
Institutional Shares. CGSMMF and CTEMMF each only have one class of shares. Each
share represents an equal proportional 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.
    
 
                                       27
<PAGE>   58
 
Shareholders are entitled to one vote for each dollar of value invested and a
proportionate fractional vote for any fraction of a dollar invested, and will
vote in the aggregate and not by series except as otherwise expressly required
by law. For example, shareholders of The Cardinal 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 accountants. However,
shareholders of The Cardinal Fund will vote as a fund, and not in the aggregate
with other shareholders of the Group, for purposes of approval of amendments to
the investment advisory agreement as it relates to The Cardinal Fund or any of
The Cardinal Fund's fundamental policies.
 
   
Overall responsibility for the management of the Funds is vested in the Board of
Trustees of the Group. See "WHO MANAGES MY INVESTMENT OF THE FUNDS?" Individual
Trustees are elected by the shareholders of the Group, although Trustees may
under certain circumstances, fill vacancies, including vacancies created by
expanding the size of the Board. Trustees 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 Ohio law. See "ADDITIONAL INFORMATION --
Miscellaneous" in the Statement of Additional Information for further
information.
    
 
An annual or special meeting of shareholders to conduct necessary business is
not required by the Declaration of Trust, the 1940 Act or other authority
except, under certain circumstances, to elect Trustees, amend the Declaration of
Trust, approve the investment advisory agreement and to satisfy certain other
requirements. To the extent that such a meeting is not required, the Group does
not intend to have an annual or special meeting.
 
The Group has represented to the Commission 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 and that the Group will
assist in communications with other shareholders as required by Section 16(c) of
the 1940 Act. At such 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 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 a 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 that 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 the Fund.
 
Shareholders should direct all inquiries concerning such matters to the Transfer
Agent in writing to 215 East Capital Street, Columbus, Ohio 43215, or by calling
(800) 282-9446.
 
Shareholders will receive unaudited semi-annual reports describing the
investment operations of the Funds and annual financial reports audited by
independent auditors.

                              INSTITUTIONAL SHARES

         The Cardinal Fund, Cardinal Balanced Fund (the "Balanced Fund") and
Cardinal Aggressive Growth Fund (the "Aggressive Growth Fund") (together called
the "Funds" or individually a "Fund") are three separate diversified investment
funds of The Cardinal Group (the "Group"), an open-end, management investment
company. The Trustees of the Group have divided each Fund's beneficial ownership
into an unlimited number of transferable units called shares (the "Shares").
Each Fund offers multiple classes of Shares.

   
         The Cardinal Fund's investment objectives are long-term growth of
capital and income. Current income is a secondary objective. The Cardinal Fund
seeks to achieve its objectives through selective participation in the long-term
progress of businesses and industries. The policy of The Cardinal Fund is
generally to invest in equity securities.

         The Balanced Fund's investment objectives are current income and
long-term growth of both capital and income.

         The Aggressive Growth Fund's investment objective is appreciation of
capital. The Aggressive Growth Fund intends to invest primarily in common stocks
and securities convertible into common stocks.
    

         There can be no assurance that any of the Funds' investment objectives
will be achieved.

         THE SHARES OF THE FUNDS ARE NOT DEPOSITS OR OBLIGATIONS OF, OR
GUARANTEED OR ENDORSED BY ANY BANK, NOR ARE SUCH SHARES FEDERALLY INSURED BY THE
U.S. GOVERNMENT, THE FEDERAL DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE
BOARD OR ANY OTHER GOVERNMENTAL AGENCY. AN INVESTMENT IN A FUND INVOLVES CERTAIN
INVESTMENT RISKS, INCLUDING THE POSSIBLE LOSS OF PRINCIPAL.

         The information set forth in the foregoing Fee Table and Example
relates only to Institutional Shares of the Funds. Each of the Funds also offers
another class of Shares known as Investor Shares. The two classes of Shares of
the Funds are subject to the same expenses except that the Investor Shares are
not subject to an administrative services fee but are subject to a Rule 12b-1
fee and are generally sold with a front-end sales charge.

an investor in the Fund will bear directly or indirectly. See "WHO MANAGES MY
INVESTMENT IN THE FUNDS?" for a more complete discussion of the shareholder
transaction expenses and annual operating expenses of the Funds. The example and
expenses above reflect current fees. THE FOREGOING EXAMPLE SHOULD NOT BE
CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES. ACTUAL EXPENSES MAY BE
GREATER OR LESS THAN THOSE SHOWN.

    
                              FINANCIAL HIGHLIGHTS

   
         The following Financial Highlights with respect to each of the years in
the ten year period ended September 30, 1996, with respect to The Cardinal Fund,
and each of the years in the three year period ended September 30, 1996, and the
period from June 24, 1993, through September 30, 1993, with respect to the
Balanced Fund and the Aggressive Growth Fund, have been audited by KPMG Peat
Marwick LLP, independent auditors, whose report thereon, in so far as it relates
to each of the years and/or periods ended September 30, 1996, are contained in
the Funds' Statement of Additional Information and may be obtained by
shareholders and prospective investors.
    

         The following Financial Highlights for The Cardinal Fund reflect the
operations of The Cardinal Fund Inc. ("TCFI"), the Cardinal Fund's predecessor,
through April 30, 1996. On May 1, 1996, The Cardinal Fund acquired all of the
assets and liabilities of TCFI and is deemed to have succeeded to the financial
and performance history of TCFI.

   
         Effective January 2, 1997, the Board of Trustees of the Group
reclassified each Fund's outstanding Shares into Investor Shares. The financial
information provided below and in the Statement of Additional Information is for
periods prior to such reclassification.

                             PERFORMANCE INFORMATION

         From time to time each Fund may advertise its average annual total
return, cumulative total return and/or yield. SUCH TOTAL RETURN FIGURES AND
YIELD FIGURES ARE BASED UPON HISTORICAL EARNINGS AND ARE NOT INTENDED TO
INDICATE FUTURE PERFORMANCE. The average annual total return advertised by a
Fund refers to the return generated by an investment in that Fund over certain
specified periods since the establishment of such Fund. The average annual total
return over a period equates the amount of an initial investment in the Fund to
the amount redeemable at the end of that period assuming that any dividends and
distributions earned by an investment in the Fund are immediately reinvested and
the maximum applicable sales charge, if any, is deducted from the initial
investment at the time of investment. Such figure is then annualized. The
cumulative total return advertised refers to the total return on a hypothetical
investment over the relevant period and equates the amount of an initial
investment in the Fund to the amount redeemable at the end of that period
assuming that any dividends and distributions are immediately reinvested and the
maximum sales charge, if any, is deducted from the initial investment. Yield
will be computed by dividing a Fund's net investment income per share earned
during a recent one-month period by such 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.

         In addition, from time to time the Balanced Fund may include in its
sales literature and shareholder reports a quote of the current "distribution"
rate for such Fund. A distribution rate is simply a measure of the level of
dividends distributed for a specified period and is computed by dividing the
total amount of dividends per share paid by the Balanced Fund during the past 12
months by a current maximum offering price. It differs from yield, which is a
measure of the income actually earned by the Balanced Fund's investments, and
from total return, which is a measure of the income actually earned by, plus the
effect of any realized and unrealized appreciation or depreciation of, such
investments during a stated period. A distribution rate is, therefore, not
intended to be a complete measure of performance. A distribution rate may
sometimes be greater than yield since, for instance, it may include short-term
and possibly long-term gains (which may be non-recurring), may not include the
effect of amortization of bond premiums and does not reflect unrealized gains or
losses.

         Investors may also judge the performance of a Fund by comparing or
referencing 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 such as those prepared by Dow Jones & Co.,
Inc. and Standard & Poor' s Corporation, and to data prepared by Lipper
Analytical Services, Inc., Morningstar, Inc. and CDA Investment


                                      -11-

Technologies, Inc. Comparisons may also be made to indices or data published in
Money Magazine, Forbes, Barron's, The Wall Street Journal, The New York Times,
The Columbus Dispatch, Business Week, U.S.A. Today and Consumer Reports. In
addition to performance information, general information about a Fund that
appears in a publication such as those mentioned above may be included in
advertisements and in reports to shareholders.

         Further information about the performance of each Fund is contained in
that Fund's Annual Report to Shareholders which may be obtained without charge
by contacting the Group at the telephone number set forth on the cover page of
this Prospectus. Performance quotations will be computed separately for Investor
and Institutional Shares. Because of differences in the fees and/or expenses
borne by Investor and Institutional Shares, the net yield and total return on
each such class can be expected, at any given time, to differ from the net yield
and total return of such other class.

                               WHAT ARE THE FUNDS?

         Each Fund is one separate diversified investment fund of the Group,
which was organized on March 23, 1993, as an Ohio business trust. The Group is
registered and operates as an open-end management investment company as defined
in the Investment Company Act of 1940, as amended (the "1940 Act"). The Cardinal
Fund was organized for the purposes of acquiring all of the assets and
liabilities of TCFI to effect a reorganization of TCFI from a stand alone
investment company to a separate series of the Group (the "Reorganization"). The
Reorganization was effected as of May 1, 1996.

                       WHAT ARE THE INVESTMENT OBJECTIVES
                           AND POLICIES OF THE FUNDS?

IN GENERAL

         The investment objectives of The Cardinal Fund are to achieve long-term
growth of capital and income. Current income is a secondary objective. The
Cardinal Fund seeks to achieve its objectives through selective participation in
the long-term progress of businesses and industries.

         The investment objectives of the Balanced Fund are to seek current
income and long-term growth of both capital and income. The Balanced Fund
intends to invest based on combined considerations of risk, income and capital
enhancement.

         The investment objective of the Aggressive Growth Fund is to seek
appreciation of capital. The Aggressive Growth Fund will invest primarily in
common stocks and securities convertible into common stocks of growth oriented
companies.


                                      -12-
<PAGE>   75
         The investment objectives of each Fund are fundamental policies and as
such may not be changed without a vote of the holders of a majority of the
outstanding Shares of that Fund (as defined below under "WHAT ARE MY RIGHTS AS A
SHAREHOLDER?"). No Fund is intended to provide a complete and balanced
investment program for an investor. There can be no assurance that the
investment objectives of any Fund will be achieved.

THE CARDINAL FUND

         The policy of The Cardinal Fund is generally to invest in equity
securities cm companies which, in the opinion of the Adviser, are growth
oriented. The securities purchased by The Cardinal Fund are traded in either
established over-the-counter markets or on national exchanges and are issued by
companies having a market capitalization of at least $10 million. This policy of
normally investing in equity securities believed to have a potential for
long-term capital appreciation means that the assets of The Cardinal Fund will
generally be subject to greater risk than may be involved in securities which do
not have such growth characteristics. It is recognized, however, that there may
be times when, as a temporary, defensive measure, The Cardinal Fund's equity
position should be reduced. At such times, and otherwise for cash management
purposes, The Cardinal Fund may hold its assets in cash or invest its assets in
investment grade debt securities, U.S. Government securities, securities of
other investment companies, repurchase agreements and preferred stock.

THE BALANCED FUND

         Under normal market conditions the Balanced Fund will invest in common
stocks, preferred stocks, fixed income securities and securities convertible
into common stocks (i.e., warrants, rights, convertible preferred stock, fixed
rate preferred stock and convertible fixed-income securities). At least 25% of
the value of the Balanced Fund's assets will be invested in fixed income senior
securities. For purposes of compliance with such 25% limitation, only that
portion of any convertible senior security attributable to its fixed income
characteristics will be used. By investing primarily in common stocks the
Balanced Fund will pursue its objectives of long-term growth of both capital and
income. However, the Balanced Fund, through its fixed-income and convertible
securities as well as the dividend attributes of certain of its common and
preferred stock holdings will place considerable emphasis on generating current
income.

         The common and preferred stocks and securities convertible into common
stocks will be selected if the Adviser believes that such securities can
contribute to the Balanced Fund's objectives of providing current income and
growth in income and/or long-term growth of capital. The Balanced Fund will
invest in the common and preferred stocks and securities convertible into common
stocks of


                                      -13-
<PAGE>   76
domestic issuers and foreign issuers (subject to the limitations described
below), with market capitalizations of not less than $10 million and which
generally are traded either in established over-the-counter markets or on
national exchanges. As described below, however, the Balanced Fund may invest in
privately placed or restricted securities.

         The Adviser will select convertible securities primarily upon its
evaluation that the underlying common stocks meet the criteria for selection of
common stocks as described above. The Balanced Fund may invest up to 10% of its
net assets in non-investment grade convertible debt securities rated no lower
than B by an appropriate nationally recognized statistical rating organization
(an "NRSRO") or in unrated securities which are deemed by the Adviser to be of
comparable quality. Non-investment grade securities are commonly referred to as
high yield or high risk securities. High yield, high risk securities are
generally riskier than higher quality securities and are subject to more credit
risk, including risk of default, and volatility than higher quality securities.
In addition, such securities have less liquidity and experience more price
fluctuation than higher quality securities.

         Convertible debt securities which are rated B by Moody's Investor
Services ("Moody's") generally lack characteristics of a desirable investment,
since the assurance of interest and principal payments or maintenance of other
terms of the contract over any long period of time may be small. Debt rated B by
Standard & Poor's Corporation ("S&P") is regarded, on balance, as predominantly
speculative with respect to capacity to pay interest and repay principal in
accordance with the terms of the obligation. While such debt will likely have
some quality and protective characteristics, these are outweighed by large
uncertainties or major risk exposures to adverse conditions. In the event that a
convertible debt security's rating falls below a "B" by the appropriate NRSROS,
the Adviser will reevaluate the security in order to determine whether to sell
or convert, if possible, such security. In such an event, however, the Balanced
Fund would not be required to liquidate such security if it would suffer a loss
on the sale of such security.

         The Balanced Fund's fixed income senior securities consist of bonds,
debentures, notes, zero-coupon securities, mortgage-related securities,
obligations issued or guaranteed by the U.S. Government or its agencies or
instrumentalities, certificates of deposit, time deposits, high quality
commercial paper and bankers' acceptances. The Balanced Fund may also invest in
repurchase agreements.

         The Balanced Fund expects to invest in a variety of bills, notes and
bonds issued by the U.S. Treasury, differing in their interest rates,
maturities, and times of issuance, as well as "stripped" U.S. Treasury
obligations such as Treasury Receipts issued by the U.S. Treasury representing
either future interest or


                                      -14-
<PAGE>   77
   
principal payments, and other obligations issued or guaranteed by the U.S.
Government or its agencies or instrumentalities. Stripped securities are issued
at a discount to their "face value" and may exhibit greater price volatility
than ordinary debt securities because of the manner in which their principal and
interest are returned to investors. Certain of such U.S. Government obligations
may have variable or floating rates of interest, whose value on the adjustment
of its interest rate can reasonably be expected to approximate its par value.
However, in the event the interest rate of such security is tied to an index or
interest rate that may from time to time lag behind other market interest
rates, there is the risk that such security's market value, upon adjustment of
its interest rate, will not approximate its par value. 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, 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 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. The Balanced Fund will invest in the obligations of
such agencies or instrumentalities only when the Adviser believes that the
credit risk with respect thereto is minimal.
    

         The Balanced Fund also expects to invest in bonds, notes and debentures
of a wide range of U.S. corporate issuers. Such obligations may be secured or
unsecured promises to pay and will in most cases differ in their interest rates,
maturities and times of issuance.

         The Balanced Fund will invest only in corporate fixed income senior
securities which are rated at the time of purchase within the four highest
rating groups assigned by an appropriate NRSRO (which are considered to be
investment grade) or, if unrated, which the Adviser deems to be of comparable
quality. For a description of the rating symbols of the NRSROS, see the Appendix
to the Statement of Additional Information. For a discussion of debt securities
rated within the fourth highest rating group assigned by an NRSRO, see "Risk
Factors and Investment Techniques -- General" below.

         Under normal market conditions, the Balanced Fund may hold up to 10% of
the value of its total assets in short-term obligations (with maturities of 12
months or less) consisting of domestic commercial paper, bankers' acceptances,
certificates of deposit and


                                      -15-
<PAGE>   78
time deposits of U.S. banks and repurchase agreements. The Balanced Fund may
also invest in securities of other investment companies, as further described
below, and in income participation loans.

         The Balanced Fund may invest in obligations of the Export-Import Bank
of the United States, in U.S. dollar denominated international securities for
which the primary trading market is in the United States ("Yankee Securities"),
or for which the primary trading market is abroad ("Eurodollar Securities"), and
in Canadian Bonds and bonds issued by institutions organized for a specific
purpose, such as the World Bank and the European Economic Community, by two or
more sovereign governments ("Supranational Agency Bonds").

         The Balanced Fund may also invest in mortgage-related securities issued
or guaranteed by the U.S. Government or its agencies or instrumentalities or by
nongovernmental entities which are rated, at the time of purchase, within the
four highest bond rating categories assigned by an appropriate NRSRO, or, if
unrated, which the Adviser deems to be of comparable quality. Under normal
market conditions, the Balanced Fund's investment in mortgage-related securities
will not exceed 25%; of the value of its total assets. Such mortgage-related
securities have mortgage obligations backing such securities, including among
others, conventional thirty year fixed rate mortgage obligations, graduated
payment mortgage obligations, fifteen year mortgage obligations and adjustable
rate mortgage obligations. All of these mortgage obligations can be used to
create pass-through securities. A pass-through security is created when mortgage
obligations are pooled together and undivided interests in the pool or pools are
sold. The cash flow from the mortgage obligations is passed through to the
holders of the securities in the form of periodic payments of interest,
principal and prepayments (net of a service fee). Prepayments occur when the
holder of an individual mortgage obligation prepays the remaining principal
before the mortgage obligation's scheduled maturity date. As a result of the
pass-through of prepayments of principal on the underlying securities,
mortgage-backed securities are often subject to more rapid prepayment of
principal than their stated maturity would indicate. Because the prepayment
characteristics of the underlying mortgage obligations vary, it is not possible
to predict accurately the realized yield or average life of a particular issue
of pass-through certificates. Prepayment rates are important because of their
effect on the yield and price of the securities. Accelerated prepayments have an
adverse impact on yields for pass-throughs purchased at a premium (i.e., a price
in excess of principal amount) and may involve additional risk of loss of
principal because the premium may not have been fully amortized at the time the
obligations are repaid. The opposite is true for pass-throughs purchased at a
discount. The Balanced Fund may purchase mortgage-related securities at a
premium or a discount. Reinvestment of


                                      -16-
<PAGE>   79
principal payments may occur at higher or lower rates than the original yield on
such securities. Due to the prepayment feature and the need to reinvest payments
and prepayments of principal at current rates, mortgage-related securities can
be less effective than typical bonds of similar maturities at maintaining yields
during periods of declining interest rates.

         Also included among the mortgage-related securities that the Balanced
Fund may purchase are collateralized mortgage obligations ("CMOs") and real
estate mortgage investment conduits ("REMICs"). CMOs may be collateralized by
whole mortgage loans but are more typically collateralized by portfolios of
mortgage pass-through securities guaranteed by the Government National Mortgage
Association, the Federal Home Loan Mortgage Corporation or the Federal National
Mortgage Association, and their income streams. Certain CMOs and REMICs are
issued by private issuers. Such securities may be eligible for purchase by the
Balanced Fund if (1) the issuer has obtained an exemptive order from the
Securities and Exchange Commission regarding purchases by investment companies
of equity interests of other investment companies or (2) such purchase is within
the limitations imposed by Section 12 of the 1940 Act.

         The Balanced Fund may also invest in asset-backed securities such as
Certificates of Automobile Receivables ("CARS") and Certificates of Amortized
Revolving Debts ("CARDS"), each of which must be rated at the time of purchase
within the four highest rating groups assigned by Moody's or S&P. For a
description of the fourth highest rating group, see "Risk Factors and Investment
Techniques" below.

         The amount invested in stocks, bonds and short-term obligations may be
varied from time to time, depending upon the Adviser's assessment of business,
economic and market conditions, including any potential advantage of price
shifts between the stock market and the bond market. The Balanced Fund reserves
the right to hold short-term securities in whatever proportion deemed desirable
for temporary defensive periods during adverse market conditions as determined
by the Adviser. However, to the extent that the Balanced Fund is so invested,
its investment objectives may not be achieved during that time.

THE AGGRESSIVE GROWTH FUND

         In determining the securities to be purchased by the Aggressive Growth
Fund, emphasis will be placed on securities of companies which, in the opinion
of the Adviser, are growth oriented and exhibit the potential for above-average
growth in earnings. The securities to be purchased by the Aggressive Growth Fund
are traded either in established over-the-counter markets or on national
exchanges and are issued by companies having a market capitalization of at least
$10 million.


                                      -17-
<PAGE>   80
         The Adviser will select convertible securities primarily upon its
evaluation that the underlying common stocks meet the criteria for selection of
common stocks as described above. The Aggressive Growth Fund may invest up to
10% of its net assets in non-investment grade convertible debt securities rated
no lower than B by an appropriate NRSRO or in unrated securities which are
deemed by the Adviser to be of comparable quality. Non-investment grade
securities are commonly referred to as high yield or high risk securities. The
characteristics and risks associated with such high risk securities are
discussed more fully above under "The Balanced Fund." In the event that a
convertible debt security's rating falls below a "B" by an NRSRO, the Adviser
will reevaluate the security in order to determine whether to sell or convert,
if possible, such security. In such an event, however, the Aggressive Growth
Fund would not be required to liquidate such security if it would suffer a loss
on the sale of such security.

         The Aggressive Growth Fund will, under normal market conditions, be
invested fully in common stocks and securities convertible into common stocks
and may engage in the investment techniques more fully described below. However,
for cash management purposes the Adviser may invest a portion of the Aggressive
Growth Fund's assets in short-term fixed income securities, consisting of
commercial paper, bankers' acceptances, certificates of deposit, obligations
issued or guaranteed by the U.S. Government or its agencies or
instrumentalities, demand and time deposits of domestic banks, repurchase
agreements and securities of other investment companies, as described below.
During temporary defensive periods, as determined by the Adviser, the Aggressive
Growth Fund may hold up to 100% of its total assets in such short-term, fixed
income securities. However, to the extent that the Aggressive Growth Fund is so
invested, the Aggressive Growth Fund is not pursuing and may not achieve its
investment objective.

RISK FACTORS AND INVESTMENT TECHNIQUES

         GENERAL. Like any investment program, an investment in any of the Funds
entails certain risks. As funds investing primarily in common stocks, each Fund
is subject to stock market risk, i.e., the possibility that stock prices in
general will decline over short or even extended periods.

         Since the Funds, to different degrees, also invest or may invest in
bonds, investors in a Fund, to the extent so invested, are also exposed to bond
market risk, i.e., fluctuations in the market value of bonds. Bond prices are
influenced primarily by changes in the level of interest rates. When interest
rates rise, the prices of bonds generally fall; conversely, when interest rates
fall, bond prices generally rise. While bonds normally fluctuate less in price
than stock, there have been in the recent past


                                      -18-
<PAGE>   81
extended periods of cyclical increases in interest rates that have caused
significant declines in bond prices.

         Current income by its nature always contributes positively to total
return. Therefore, the current income expected to be generated from an
investment in the Balanced Fund will counterbalance to some degree the adverse
price fluctuations of the securities held by the Balanced Fund. The effective
result should therefore be lower total return volatility for the Balanced Fund
than a fund which does not provide such current income.

         The Aggressive Growth Fund is intended for investors who can accept the
higher risks involved in seeking potentially higher capital appreciation through
investments in growth oriented companies. A growth oriented company typically
invests most of its net income in its enterprise and does not pay out much, if
any, in dividends. Accordingly, the Aggressive Growth Fund does not anticipate
any significant distributions to shareholders from net investment income, and
potential investors should be in a financial position to forego current income
from their investment in the Aggressive Growth Fund. The securities of less
seasoned companies may have limited marketability and may be subject to more
abrupt or erratic market movements over time than securities of more seasoned
companies or the market as a whole.

         The Balanced Fund may invest in certain variable or floating rate
government securities and, as described below, each Fund may invest in put and
call options and futures. Such instruments are considered to be "derivatives." A
derivative is generally defined as an instrument whose value is based upon, or
derived from, some underlying index, reference rate (e.g., interest rates),
security, commodity or other asset. No Fund will not invest more than 10% of its
total assets in any such derivatives at any one time.

         REPURCHASE AGREEMENTS. Securities held by each Fund may be subject to
repurchase agreements. Under the terms of the repurchase agreement, a Fund would
acquire securities from a financial institution such as a well-established
securities dealer or a bank which is a member of the Federal Reserve System
which the Adviser deems creditworthy under guidelines approved by the Group's
Board of Trustees. At the time of purchase, the bank or securities dealer agrees
to repurchase the underlying securities from that Fund at a specified time and
price. The resale price reflects the purchase price plus an agreed upon market
rate of interest which is unrelated to the coupon rate or maturity of the
underlying security. A Fund will only enter into a repurchase agreement where
(i) the underlying securities are of the type which such Fund's investment
policies would allow it to purchase directly, (ii) the market value of the
underlying security, including interest accrued, will at all times be equal to
or exceed the value of the repurchase agreement, and (iii) payment for the
underlying securities is made only upon physical delivery or evidence of book-


                                      -19-
<PAGE>   82
entry transfer to the account of such Fund's custodian or a bank acting as
agent. The Adviser will be responsible for continuously monitoring such
requirements.

         WHEN-ISSUED AND DELAYED-DELIVERY TRANSACTIONS. The Balanced Fund may
also purchase securities on a when-issued or delayed-delivery basis. The
Balanced 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, although such transactions
represent a form of leveraging. 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. The Balanced Fund
will not pay for such securities or start earning interest on them until they
are received. When the Balanced Fund agrees to purchase such securities, its
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, the Balanced Fund relies on the seller to
complete the transaction; the seller's failure to do so may cause the Balanced
Fund to miss a price or yield considered to be advantageous.

         The Balanced Fund's commitments to purchase when-issued securities will
not exceed 25% of the value of its total assets absent unusual market
conditions. In the event that its commitments to purchase when-issued securities
ever exceed 25% of the value of its assets, the Balanced Fund's liquidity and
the ability of the Adviser to manage it might be adversely affected.

         MEDIUM-GRADE SECURITIES. As described above, the Balanced Fund and the
Aggressive Growth Fund may each invest in securities within the fourth highest
rating group assigned by an NRSRO, (e.g. BBB or Baa by S&P and Moody's,
respectively) and comparable unrated securities. These types of debt securities
are considered by Moody's to have some speculative characteristics, and are more
vulnerable to changes in economic conditions, higher interest rates or adverse
issuer-specific developments which are more likely to lead to a weaker capacity
to make principal and interest payments than comparable higher rated debt
securities.

         Should subsequent events cause the rating of a debt security purchased
by the Balanced Fund or the Aggressive Growth Fund to fall below BBB or Baa, as
the case may be, the Adviser will consider such an event in determining whether
that Fund should continue to hold that security. In no event, however, would
such Funds be required to liquidate any such portfolio security where the Fund
would suffer a loss on the sale of such security.


                                      -20-
<PAGE>   83
         FOREIGN SECURITIES. Each Fund may also invest up to 25% of its net
assets in foreign securities through the purchase of sponsored and unsponsored
American Depositary Receipts ("ADRs"). ADRs are receipts typically issued by a
United States bank or trust company evidencing ownership of the underlying
foreign securities and are denominated in U.S. dollars. Institutions issuing
ADRs may not be sponsored by the issuer. Unsponsored ADRs may be less liquid
than sponsored ADRS, and there may be less information available regarding the
underlying foreign issuer for unsponsored ADRs since a non-sponsored institution
is not required to provide the same shareholder information that a sponsored
institution is required to provide under its contractual arrangements with the
issuer.

   
         Investments in foreign securities, including ADRs, is subject to
special investment 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 or interest income, possible seizure, nationalization, or
expropriation of foreign investments or deposits, less stringent disclosure
requirements, the possible establishment of exchange controls or taxation at the
source, or the adoption of other foreign governmental restrictions. In addition,
foreign issuers may be subject to different accounting, auditing, reporting, and
recordkeeping standards than those applicable to U.S. domestic issuers, and
securities markets in foreign countries may be structured differently from and
may not be as liquid as the U.S. markets. A Fund will acquire securities issued
by foreign issuers only when the Adviser believes that the risks associated with
such investments are minimal.
    

         RESTRICTED SECURITIES. Securities in which the Balanced Fund may invest
include securities issued by corporations without registration under the
Securities Act of 1933, as amended (the "1933 Act"), including securities issued
in reliance on the so-called "private placement" exemption from registration
which is afforded by Section 4(2) of the 1933 Act ("Section 4(2) securities").
Section 4(2) securities are restricted as to disposition under the Federal
securities laws, and generally are sold to institutional investors such as the
Balanced Fund who agree that they are purchasing the securities for investment
and not with a view to public distribution. Any resale must also generally be
made in an exempt transaction. Section 4(2) securities are normally resold to
other institutional investors through or with the assistance of the issuer or
investment dealers who assist in the placement of such Section 4(2) securities,
thus providing some liquidity.

         Pursuant to procedures adopted by the Board of Trustees of the Group,
the Adviser may determine Section 4(2) securities to be liquid if such
securities are eligible for resale under Rule 144A


                                      -21-
<PAGE>   84
under the 1933 Act and are readily saleable. Rule 144A permits the Balanced Fund
to purchase securities which have been privately placed and resell such
securities to certain qualified institutional buyers without restriction. For
purposes of determining whether a Rule 144A security is readily saleable, and
therefore liquid, the Adviser must consider, among other things, the frequency
of trades and quotes for the security, the number of dealers willing to purchase
or sell the security and the number of potential purchasers, dealer undertakings
to make a market in the security, and the nature of the security and marketplace
trades of such security. However, investing in Rule 144A securities, even if
such securities are initially determined to be liquid, could have the effect of
increasing the level of the Balanced Fund's illiquidity to the extent that
qualified institutional buyers become, for a time, uninterested in purchasing
these securities.

   
         REITs. Each of the Funds may also invest in securities of equity real
estate investment trusts ("REITs"). REITs pool investors' funds for investment
primarily in commercial real estate properties. Investment in REITs may subject
a Fund to certain risks. REITs may be affected by changes in the value of the
underlying property owned by the trusts. REITs are dependent upon specialized
management skill, may not be diversified and are subject to the risks of
financing projects. REITs are also subject to heavy cash flow dependency,
defaults by borrowers, self liquidation and the possibility of failing to
qualify for the beneficial tax treatment available to REITs under the Internal
Revenue Code and to maintain its exemption from the 1940 Act. As a shareholder
in a REIT, a Fund would bear, along with other shareholders, its pro rata
portion of the REIT's operating expenses. These expenses would be in addition
to the advisory and other expenses that the Fund bears directly in connection
with its own operations.
    

         PUT AND CALL OPTIONS. Subject to its investment policies and for
purposes of hedging against market risks related to its portfolio securities,
each Fund may purchase put and call options on securities. Purchasing options is
a specialized investment technique that entails a substantial risk of a complete
loss of the amounts paid as premiums to writers of options. A Fund will purchase
put options only on securities in which the Fund may otherwise invest. Each Fund
may also engage in writing call options from time to time as the Adviser deems
appropriate. Each Fund will write only covered call options (options on
securities owned by that Fund). In order to close out a call option it has
written, a Fund will 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 has written. when a
portfolio security subject to a call option is sold, such Fund will effect a
closing purchase transaction to close out any existing call option on that
security. If the 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 market
conditions, it is not expected that the underlying value of portfolio securities
subject to such options would exceed 25% of the net assets of a Fund.

         Each Fund, as part of its option transactions, also may purchase index
put and call options and write index options. As with options on individual
securities, a Fund will write only covered index call options. Through the
writing or purchase of index options a Fund can achieve many of the same
objectives as through the use of options on individual securities. options on
securities indices are similar to options on a security except that, rather than
the right to take or make delivery of a security at a specified price, an option
on a securities index gives the holder the right to receive, upon exercise of
the option, an amount of cash if the closing level of the securities index upon
which the


                                      -22-
<PAGE>   85
option is based is greater than, in the case of a call, or less than, in the
case of a put, the exercise price of the option.

         Price movements in securities which a Fund owns or intends to purchase
probably will not correlate perfectly with movements in the level of an index
and, therefore, a Fund bears the risk of a loss on an index option that is not
completely offset by movements in the price of such securities. Because index
options are settled in cash, a call writer cannot determine the amount of its
settlement obligations in advance and, unlike call writing on specific
securities, cannot provide in advance for, or cover, its potential settlement
obligations by acquiring and holding the underlying securities. A Fund may be
required to segregate assets or provide an initial margin to cover index options
that would require it to pay cash upon exercise.

         FUTURES CONTRACTS. Each Fund may also enter into contracts for the
future delivery of securities and futures contracts based on a specific
security, class of securities or an index, purchase or sell options on any such
futures contracts and engage in related closing transactions. A futures contract
on a securities index is an agreement obligating either party to pay, and
entitling the other party to receive, while the contract is outstanding, cash
payments based on the level of a specified securities index.

         Each Fund may engage in such futures contracts in an effort to hedge
against market risks. For example, when interest rates are expected to rise or
market values of portfolio securities are expected to fall, a Fund can seek
through the sale of futures contracts to offset a decline in the value of its
portfolio securities. When interest rates are expected to fall or market values
are expected to rise, a Fund, through the purchase of such contracts, can
attempt to secure better rates or prices for such Fund than might later be
available in the market when it effects anticipated purchases.

         The acquisition of put and call options on futures contracts will,
respectively, give a Fund the right (but not the obligation), for a specified
price, to sell or to purchase the underlying futures contract, upon exercise of
the option, at any time during the option period.

         Aggregate initial margin deposits for futures contracts, and premiums
paid for related options, may not exceed five percent of a Fund' s total assets,
and the value of securities that are the subject of such futures and options
(both for receipt and delivery) may not exceed one-third of the market value of
a Fund's total assets. Futures transactions will be limited to the extent
necessary to maintain each Fund's qualification as a regulated investment
company.


                                      -23-
<PAGE>   86
         Futures transactions involve brokerage costs and require a Fund to
segregate assets to cover contracts that would require it to purchase
securities. A Fund may lose the expected benefit of futures transactions if
interest rates or securities prices move in an unanticipated manner. Such
unanticipated changes may also result in poorer overall performance than if the
Fund had not entered into any futures transactions. In addition, the value of a
Fund's futures positions may not prove to be perfectly or even highly correlated
with the value of its portfolio securities, limiting such Fund's ability to
hedge effectively against interest rate and/or market risk and giving rise to
additional risks. There is no assurance of liquidity in the secondary market for
purposes of closing out futures positions.

         INVESTMENT COMPANY SECURITIES. Each Fund may also invest up to 10% of
the value of its total assets in the securities of other investment companies
subject to the limitations set forth in the 1940 Act. Each Fund intends to
invest in the securities of other investment companies which, in the opinion of
the Adviser, will assist such Fund in achieving its objectives and in money
market mutual funds for purposes of short-term cash management. A Fund's
investment in such other investment companies may result in the duplication of
fees and expenses, particularly investment advisory fees. For a further
discussion of the limitations on each Fund's investments in other investment
companies, see "INVESTMENT OBJECTIVES AND POLICIES -- Additional Information on
Portfolio Instruments -- Securities of Other Investment Companies" in the
Group's Statement of Additional Information.

INVESTMENT RESTRICTIONS

         Each 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 that Fund (as
defined below under "WHAT ARE MY RIGHTS AS A SHAREHOLDER?").

         Each 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, more than 5%
         of the value of the Fund's total assets would be invested in such
         issuer, or the Fund would hold more than 10% of the outstanding voting
         securities of the issuer, except that up to 25% of the value of the
         Fund's total assets may be invested without regard to such limitations.
         There is no limit to the percentage of assets that may be invested in
         U.S. Treasury bills, notes, or other obligations issued or guaranteed
         by the U.S. Government or its agencies or instrumentalities.


                                      -24-
<PAGE>   87
                  2. 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) 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.

                  3. Borrow money or issue senior securities, except that the
         Fund may borrow from banks or enter into reverse repurchase agreements
         or dollar roll agreements for temporary purposes in amounts up to 10%
         of the value of its total assets at the time of such borrowing and
         except as permitted pursuant to an exemption from the 1940 Act. The
         Fund will not purchase securities while its borrowings (including
         reverse repurchase agreements and dollar roll agreements) exceed 5% of
         its total assets.

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

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

         Each Fund will not:

                  1. Purchase or otherwise acquire any securities, if as a
         result, more than 15% of the Fund's net assets would be invested in
         securities that are illiquid.

              HOW DO I PURCHASE INSTITUTIONAL SHARES OF THE FUNDS?

GENERAL

         Each Fund's Institutional Shares are continuously offered and may be
purchased through procedures established by The Ohio Company, principal
underwriter of the Funds' Shares, in connection with accounts for which banks,
broker-dealers, savings and loan associations, trust companies (including The
Ohio Company), qualified investment advisers and certain other financial
institutions serve in a fiduciary capacity on behalf of customers


                                      -25-
<PAGE>   88
or beneficiaries (collectively, "Financial Institutions"). Normally, Financial
Institutions will hold Institutional Shares of record for their customers or
beneficiaries. With respect to Institutional Shares so sold, it is the
responsibility of the holder of record to transmit purchase or redemption orders
to The Ohio Company and to deliver funds for the purchase thereof on a timely
basis. Beneficial ownership of Institutional Shares of the Funds may be recorded
by the Financial Institutions and reflected in the account statements provided
to their customers or beneficiaries.

         The Group reserves the right to reject any order for the purchase of
Institutional Shares in whole or in part. The applicable Financial Institution
will receive a confirmation of each new transaction in its account. Certificates
representing Shares will not be issued.

         Institutional Shares are purchased at the net asset value per share
(see "HOW IS NET ASSET VALUE CALCULATED?") next determined after receipt by The
Ohio Company or its agents of an order and payment. There is no sales charge
imposed in connection with the purchase of Institutional Shares of any Fund.
Depending upon the terms of a particular account, a Financial Institution may
charge customer account fees for services provided in connection with an
investment in a Fund. Information concerning these services and any charges may
be obtained from such Financial Institution. This Prospectus should be read in
conjunction with any such information so received.

         From time to time, The Ohio Company, from its own resources, may
provide compensation to securities dealers in connection with sales of shares of
the Cardinal Funds. Such compensation will include financial assistance to
securities dealers in connection with conferences, sales or training programs
for their employees, seminars for the public, advertising, sales campaigns
and/or shareholder services and programs regarding one or more of the Cardinal
Funds and other dealer-sponsored programs or events. In some instances, this
compensation may be made available only to certain securities dealers whose
representatives have sold or are expected to sell significant amounts of shares
of the Cardinal Funds. Compensation will 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. Securities
dealers may not use sales of a Fund's Shares to qualify for this compensation to
the extent such may be prohibited by the laws of any state or any self
regulatory agency, such as the National Association of Securities Dealers, Inc.
In addition, The Ohio Company may make ongoing payments to brokerage firms,
financial institutions (including banks) and others to facilitate the
administration and servicing of


                                      -26-
<PAGE>   89
shareholder accounts.  None of the aforementioned additional
compensation is paid for by any Fund or its shareholders.

                       WHAT DISTRIBUTIONS WILL I RECEIVE?

         Dividends and distributions shall be made with such frequency (long
term capital gains normally will be distributed only once annually) and in such
amounts as the Group from time to time shall determine and shall be paid from
net income and net realized capital gains of the Funds. It is the policy of each
Fund to distribute, at least annually, substantially all of its net investment
income and to distribute annually any net realized capital gains. Unless a
shareholder specifically requests otherwise in writing to the Transfer Agent,
dividends and distributions will be made only in additional full and fractional
Institutional Shares of a Fund and not in cash. Dividends are paid in cash not
later than seven days after a shareholder's complete redemption of his
Institutional Shares in a Fund.

         Each Fund's net investment income available for distribution to the
holders of Institutional Shares will be reduced by the amount of administrative
services fees paid under the Services Plan described below.

                    HOW MAY I REDEEM MY INSTITUTIONAL SHARES?

         Investors may redeem Institutional Shares of a Fund on any Business Day
at the net asset value per Institutional Share next determined following receipt
by the Transfer Agent, 215 East Capital Street, Columbus, Ohio 43215, of written
or telephonic notice to redeem, as described more fully below. See "HOW IS NET
ASSET VALUE CALCULATED?", below, for a description of when net asset value is
determined.

         As requested, The Ohio Company, on behalf of a shareholder, will
forward the foregoing notice to redeem to the Transfer Agent without charge.
Other broker-dealers may assist a shareholder in redeeming his Institutional
Shares and may charge a fee for such services.

         The Group will make payment for redeemed Institutional Shares as
promptly as practicable but in no event more than seven days after receipt by
the Transfer Agent of the foregoing notice. The Group reserves the right to
delay payment for the redemption of Institutional Shares where such
Institutional Shares were purchased with other than immediately available funds,
but only until the purchase payment has cleared (which may take fifteen or more
days from the date the purchase payment is received by the applicable Fund). The
purchase of Institutional Shares by wire transfer of federal funds would avoid
any such delay.


                                      -27-
<PAGE>   90
         The Group intends to pay cash for all Institutional Shares redeemed,
but, under abnormal conditions which make payment in cash unwise, the Group may
make payment wholly or partly in readily marketable portfolio securities at
their then market value equal to the redemption price. In such cases, an
investor may incur brokerage costs in converting such securities to cash.

         The Group may suspend the right of redemption or may delay payment
during any period the determination of net asset value is suspended. See "HOW IS
NET ASSET VALUE CALCULATED?"

         Due to the high cost of maintaining accounts, the Group reserves the
right to redeem, at net asset value, involuntarily Shares in any account at the
then current net asset value if at any time redemptions (but not as a result of
a decrease in the market price of such Shares or the deduction of any sales
charge) have reduced a shareholder's total investment in a Fund to a net asset
value below $500. A shareholder will be notified in writing that the value of
Fund Shares in the account is less than $500 and allowed not less than 30 days
to increase his investment in such Fund to $500 before the redemption is
processed. Proceeds of redemptions so processed, including dividends declared to
the date of redemption, will be promptly paid to the shareholder.

REDEMPTION BY MAIL

         Shareholders may redeem Institutional Shares of a Fund by submitting a
written request therefor to the Transfer Agent, at 215 East Capital Street,
Columbus, Ohio 43215. The Transfer Agent will request a signature guarantee by
an eligible guarantor institution as described below. However, a signature
guarantee will not be required if (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, provided, however, that the address of
record has not been changed within the preceding 15 days. For purposes of this
policy, an "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 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 or
(2) it has reason to believe that the transaction would otherwise be improper.

REDEMPTION BY TELEPHONE

         Shareholders may redeem Institutional Shares of a Fund by calling the
Group at the telephone number set forth on the front of this Prospectus. The
shareholder may direct that the redemption proceeds be mailed to the address of
record.


                                      -28-
<PAGE>   91
         Neither the Group, the Funds nor their service providers will be liable
for any loss, damages, expense or cost arising out of any telephone redemption
effected in accordance with the Group's telephone redemption procedures, acting
upon instructions reasonably believed to be genuine. The Group will employ
procedures designed to provide reasonable assurances that instructions by
telephone are genuine; if these procedures are not followed, the Group, the
Funds or their service providers may be liable for any losses due to
unauthorized or fraudulent instructions. These procedures may include recording
all phone conversations, sending confirmations to shareholders within 72 hours
of the telephone transaction, and verification of account name and account
number or tax identification number. If, due to temporary adverse conditions,
investors are unable to effect telephone transactions, shareholders may also
redeem their Institutional Shares by mail as described above.

                  WHAT OTHER SHAREHOLDER PROGRAMS ARE PROVIDED?

ACH PROCESSING

         The Group offers ACH privileges. Investors may use ACH processing to
make subsequent purchases, redeem Shares and/or electronically transfer
distributions paid on Shares, in addition to the other methods described in this
Prospectus. ACH provides a method by which funds may be automatically
transferred to or from an authorized bank account at a Federal Reserve member
bank that is an ACH member. Please contact your representative if you are
interested in ACH processing.

EXCHANGE PRIVILEGE

         Holders of Institutional Shares of a Fund may, provided the amount to
be exchanged meets the applicable minimum investment requirements and the
exchange is made in states where it is legally authorized, exchange, at
respective net asset values, Institutional Shares of any Fund for Institutional
Shares of another Fund or for:

         Institutional Shares of Cardinal
         Government Obligations Fund, a fund
         investing in securities issued or
         guaranteed by the U.S. Government;

         Shares of Cardinal Government Securities
         Money Market Fund, a U.S. Government securities
         money market fund; or

         Shares of Cardinal Tax Exempt Money Market
         Fund, a tax-free money market fund.

         The foregoing exchange privilege must be made by written or telephonic
authorization. A shareholder should notify The Ohio


                                      -29-
<PAGE>   92
Company of his desire to make an exchange, and The Ohio Company will furnish, as
necessary, a prospectus and an application form to open the account. The
Transfer Agent will require that any written authorization of an exchange
include a signature guarantee as described above under "HOW MAY I REDEEM MY
SHARES? -- Redemption by mail." However, a signature guarantee will not be
required if the exchange requested is within the same account or into an
existing account of the shareholder held in the same name or names and in the
same capacity as the account from which the exchange is to be made. Shareholders
may also authorize an exchange of Shares of a Fund by telephone. Neither the
Group, the Funds nor any of their service providers will be liable for any loss,
damages, expense or cost arising out of any telephone exchange authorization to
the extent and subject to the requirements set forth under "HOW MAY I REDEEM MY
SHARES? -- Redemption by telephone" above.

         In the event the status of a shareholder or the capacity in which a
shareholder holds his Institutional Shares changes such that he is no longer
eligible to purchase or hold Institutional Shares of a Fund, then such
Institutional Shares will be automatically exchanged for Investor Shares of such
Fund at respective net asset values.

         For tax purposes, an exchange is treated as a redemption and a new
purchase.

         The Group may, at any time, modify or terminate the foregoing exchange
privilege. The Group, however, will give shareholders of the Funds 60 days'
advance written notice of any such modification or termination.

                       HOW IS NET ASSET VALUE CALCULATED?

         The net asset value of each Fund is determined once daily as of 4:00
P.M. Eastern Time, on each Business Day. A "Business Day" is a day on which the
New York Stock Exchange is open for business and any other day (other than a day
on which no Shares of such Fund are tendered for redemption and no order to
purchase any Shares of that Fund is received) during which there is a sufficient
degree of trading in a Fund's portfolio securities that the net asset value
might be materially affected by changes in the value of the portfolio
securities. The net asset value per share of each class of shares of a Fund is
computed by dividing the sum of the value of that Fund's portfolio securities
plus any cash and other assets (including interest and dividends accrued but not
received) allocable to such class minus all liabilities (including estimated
accrued expenses) allocable to such class by the total number of Shares of that
class of such Fund then outstanding.

         The net asset value per share will fluctuate as the value of the
investment portfolio of a Fund changes.


                                      -30-
<PAGE>   93
         Portfolio securities which are traded on United States stock exchanges
are valued at the last sale price on such an exchange as of the time of
valuation on the day the securities are being valued. Securities traded in the
over-the-counter market are valued at either the mean between the bid and ask
prices or the last sale price as one or the other may be quoted by the National
Association of Securities Dealers Automated Quotation System ("NASDAQ") as of
the time of valuation on the day the securities are being valued. The Group uses
one or more pricing services to provide such market quotations. Securities and
other assets for which market quotations are not readily available are valued at
fair value as determined in good faith by or under the direction of the Board of
Trustees of the Group.

         Determination of the net asset value may be suspended at times when (a)
trading on the New York Stock Exchange is restricted by applicable rules and
regulations of the Commission, (b) the New York Stock Exchange is closed for
other than customary weekend and holiday closings, (c) an emergency exists as a
result of which disposal by the Group of portfolio securities owned by the Fund
or valuation of net assets of the Fund is not reasonably practicable, or (d) the
Commission has by order permitted such suspension.

                      DO THE FUNDS PAY FEDERAL INCOME TAX?

         Each of the funds of the Group, including the Funds, is treated as a
separate entity for federal income tax purposes and intends to qualify as a
"regulated investment company" under the Code for so long as such qualification
is in the best interest of that fund's shareholders. Qualification as a
regulated investment company under the Code requires, among other things, that
the regulated investment company distribute to its shareholders at least got of
its investment company taxable income. Each Fund contemplates declaring as
dividends 100% of such Fund's investment company taxable income (before
deduction of dividends paid).

         A non-deductible 4% excise tax is imposed on regulated investment
companies that do not distribute in each calendar year (regardless of whether
they otherwise have a non-calendar taxable year) an amount equal to 98% of their
ordinary income for the calendar year plus 98% of their capital gain net income
for the one-year period ending on October 31 of such calendar year. The balance
of such income must be distributed during the next calendar year. If
distributions during a calendar year were less than the required amount, the
Fund would be subject to a nondeductible excise tax equal to 4% of the
deficiency.

                              WHAT ABOUT MY TAXES?

         It is expected that each Fund will distribute annually to shareholders
all or substantially all of that Fund's net ordinary income and net realized
capital gains and that such distributed net


                                      -31-
<PAGE>   94
ordinary income and distributed net realized capital gains will be taxable
income to shareholders for federal income tax purposes, even if paid in
additional Shares of the Fund and not in cash. The dividends received deduction
for corporations will apply to the aggregate of such ordinary income
distributions in the same proportion as the aggregate dividends eligible for the
dividends received deduction, if any, received by a Fund bear to its gross
income.

         Distribution by a Fund of the excess of net long-term capital gain over
net short-term capital loss is taxable to shareholders as long-term capital gain
in the year in which it is received, regardless of how long the shareholder has
held the Shares. Such distributions are not eligible for the dividends received
deduction.

         If the net asset value of a Share is reduced below the shareholder's
cost of that Share by the distribution of income or gain realized on the sale of
securities, the distribution is a return of invested principal, although taxable
as described above.

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

         Foreign taxes may be imposed on a Fund by foreign countries with
respect to its income from foreign securities. Since less than 50% in value of
each Fund's total assets at the end of its fiscal year are expected to be
invested in securities of foreign corporations, no Fund will be entitled under
the Code to pass through to its shareholders their pro rata share of the foreign
taxes paid by such Fund. These taxes will be taken as a deduction by that Fund.

         The foregoing is intended only as a brief summary of some of the
important tax considerations generally affecting the Funds and their
shareholders. Potential investors in the Funds are urged to consult their tax
advisers concerning the application of federal, state and local taxes as such
laws and regulations affect their own tax situation.

         The Transfer Agent will inform shareholders at least annually of the
amount and nature of such income and capital gains.


                                      -32-
<PAGE>   95
                     WHO MANAGES MY INVESTMENT IN THE FUNDS?
   
         Except where shareholder action is required by law, all of the
authority of the Group is exercised under the direction of the Group's Trustees.
Unless so required by the Group's Declaration of Trust or By-Laws or by Ohio
law, at any given time all Trustees may not have been elected by the
shareholders of the Group. The Trustees are empowered to elect officers and
contract with and provide for the compensation of agents, consultants and other
professionals to assist and advise in its day-to-day operations. The Group will
be managed in accordance with its Declaration of Trust and the laws of Ohio
governing business trusts.
    

         The Trustees of the Group 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 the Adviser or The Ohio Company receives any
compensation from the Group for acting as a Trustee of the Group. The officers
of the Group receive no compensation directly from the Group for performing the
duties of their offices. The Adviser receives fees from the Group for acting as
investment adviser and manager and as dividend and transfer agent and for
providing certain fund accounting services. The Ohio Company receives no fees
under its Distribution Agreement with the Group with respect to Institutional
Shares of the Funds, but may receive fees under the Administrative Services Plan
discussed below.

INVESTMENT ADVISER AND MANAGER

         Cardinal Management Corp. (the "Adviser"), 155 East Broad Street,
Columbus, Ohio 43215, a wholly owned subsidiary of The Ohio Company, is the
investment adviser and manager of each of the Funds. The Adviser is also the
investment adviser and manager of each of the other Cardinal Funds.
   
         The Ohio Company, an investment banking firm organized in 1925, is a
member of the New York and Chicago Stock Exchanges, other regional stock
exchanges and the National Association of Securities Dealers, Inc. Descendants
of H. P. and R. F. Wolfe, deceased, and members of their families, through their
possession of a majority of voting stock, may be considered controlling persons
of The Ohio Company. The Ohio Company serves as the principal underwriter for
each of the Cardinal Funds.
    
         In its capacity as investment adviser, and subject to the ultimate
authority of the Group's Board of Trustees, the Adviser, in accordance with the
Funds' investment objectives and policies, manages each Fund, and makes
decisions with respect to and places orders for all purchases and sales of its
portfolio securities. Since the Reorganization with respect to The Cardinal Fund
and since December 22, 1995, with respect to TCFI, The Cardinal Fund's
predecessor, John Bevilacqua has been primarily responsible for the day-to-day
management of the portfolio of such Funds. Mr.


                                      -33-
<PAGE>   96
   
Bevilacqua has been a Vice President and Portfolio Manager for The Ohio Company
since October, 1994. Prior thereto, and since February, 1984, Mr. Bevilacqua
served as Second Vice President -- Investments for Midland Mutual Life Insurance
Company, Columbus, Ohio. Since October 1, 1996, David C. Will and Joseph A.
Miner have been responsible jointly for the day-to-day management of the
Balanced Fund's portfolio. Mr. Will has been a Vice President of the Adviser and
The Ohio Company since 1990 and has more than 25 years of investment management
experience. Mr. Miner has been a Vice President and Senior Portfolio Manager of
the Adviser and/or The Ohio Company since August, 1995. Prior thereto and since
1992, Mr. Miner was a Vice President and Portfolio Manager with Key Trust
Company of Ohio. From 1987 to 1992, Mr. Miner was an investment strategist and
an Assistant Vice President of Citizens Fidelity Capital Management Company,
Louisville, Kentucky. Since August 12, 1996, Mr. Harold C. Elliott has been
primarily responsible for the day-to-day management of the Aggressive Growth
Fund's portfolio. Mr. Elliott has been a Vice President and Chief Investment
Officer of The Ohio Company since March, 1996. Prior thereto, from May, 1993 to
March, 1996, Mr. Elliott was Vice President and Chief Investment Officer of The
Bank of Tokyo Trust Company (New York City), a wholly-owned subsidiary of The
Bank of Tokyo Limited, Tokyo, Japan. Prior thereto, from December, 1984 to May,
1993, Mr. Elliott was employed by First Fidelity Bank, Philadelphia,
Pennsylvania.
    

         In addition, pursuant to the Investment Advisory Agreement, the Adviser
generally assists in all aspects of each Fund's administration and operation.

         For the services provided and expenses assumed pursuant to its
investment advisory agreement with the Group with respect to the Funds, the
Adviser receives a fee from the Funds, computed daily and paid monthly at the
following annual rates: with respect to The Cardinal Fund, 0.60% of such Fund's
average daily net assets; and with respect to both the Balanced Fund and the
Aggressive Growth Fund, 0.75% of such Funds' average daily net assets. While in
the opinion of the staff of the Commission such fees with respect to the
Balanced Fund and the Aggressive Growth Fund are higher than the advisory fee
paid by most mutual funds, the Group's Board of Trustees believes them to be
comparable to advisory fees paid by many funds having similar objectives and
policies.

         The Adviser may periodically waive all or a portion of its advisory fee
with respect to a Fund to increase the net income of such Fund available for
distribution as dividends. The waiver of such fee will cause the return and/or
yield of such Fund to be higher than it would otherwise be in the absence of
such a waiver.


                                      -34-

DIVIDEND AND TRANSFER AGENT AND FUND ACCOUNTANT

   
         The Group has entered into a Transfer Agency and Fund Accounting
Agreement with Cardinal Management Corp. (the "Transfer Agent"), 215 East
Capital Street, Columbus, Ohio 43215, pursuant to which the Transfer Agent has
agreed to act as the Funds' transfer agent and dividend disbursing agent. In
consideration of such services, each Fund has agreed to pay the Transfer Agent
an annual fee, paid monthly, equal to $18 per shareholder account plus out-
of-pocket expenses. In addition, the Transfer Agent provides certain fund
accounting services for the Funds. The Transfer Agent receives a fee from each
Fund for such services equal to a fee computed daily and paid periodically at an
annual rate of .03% of that Fund' s average daily net assets of up to $100
million and .01% of such Fund's average daily net assets in excess of $100
million.
    

DISTRIBUTOR

         The Group has entered into a Distributor's Contract with The Ohio
Company, 155 East Broad Street, Columbus, Ohio 43215, pursuant to which Shares
of the Funds will be offered continuously on a best efforts basis by The Ohio
Company and dealers selected by The Ohio Company. H. Keith Allen is an officer
and trustee of the Group and an officer and director of The Ohio Company. Frank
W. Siegel is an officer and trustee of the Group and an officer of The Ohio
Company. James M. Schrack II is an officer of both the Group and The Ohio
Company. The Ohio Company receives no compensation under the Distributor's
Contract with respect to distribution of the Institutional Shares of the Funds.

EXPENSES

         The Adviser bears all expenses in connection with the performance of
its services as investment adviser, manager, transfer agent and fund accountant
other than the cost of securities (including brokerage commissions, if any)
purchased for the Funds. The Trustees reserve the right to allocate certain
other expenses, which can reasonably be identified as relating to a particular
class, solely to such class, including Institutional Shares, as they deem
appropriate ("Class Expenses"). Such expenses include (a) transfer agency fees
identified as being attributable to a specific class; (b) printing and postage
expenses related to preparing and distributing materials such as shareholder
reports, prospectuses and proxy statements to current shareholders of a specific
class; (c) Blue Sky registration fees incurred by a class of shares; (d) SEC
registration fees incurred by a class; (e) expenses of administrative personnel
and services as required to support the shareholders of a specific class; (f)
litigation or other legal expenses and audit or other accounting expenses
relating solely to one class; (g) trustees, fees or expenses


                                      -35-
<PAGE>   98
incurred as a result of issues relating to one class; and (h) shareholder
meeting costs that relate to a specific class.

ADMINISTRATIVE SERVICES PLAN

         The Group has adopted an Administrative Services Plan with respect to
each Fund's Institutional Shares (the "Services Plan") pursuant to which each
Fund is authorized to pay compensation to Financial Institutions, which may
include The Ohio Company, which agree to provide certain ministerial, record
keeping and/or administrative support services for their customers, account
holders or beneficiaries (collectively, "customers") who are the beneficial or
record owner of Institutional Shares of a Fund. In consideration for such
services, a Financial Institution receives a fee from such Fund, computed daily
and paid monthly, at an annual rate of up to .15% of the average daily net asset
value of Institutional Shares of that Fund owned beneficially or of record by
such Financial Institution's customers for whom the Financial Institution
provides such services.

         The servicing agreements adopted under the Services Plan (the
"Servicing Agreements") require the Financial Institutions receiving such
compensation to perform certain ministerial, record keeping and/or
administrative support services with respect to the beneficial or record owners
of Institutional 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 Institutional Shares of
that Fund, providing sub-accounting with respect to Institutional Shares
beneficially owned by such customers and providing customers with a service that
invests the assets of their accounts in Institutional Shares of a Fund pursuant
to specific or pre-authorized instructions.

         As authorized by the Services Plan, the Group has entered into a
Servicing Agreement with The Ohio Company pursuant to which The Ohio Company has
agreed to provide certain administrative support services in connection with
Institutional Shares of the Funds owned of record or beneficially by its
customers for whom The Ohio Company provides fiduciary or trust services. Such
administrative support services may include, but are not limited to, (i)
processing dividend and distribution payments from the Fund on behalf of
customers; (ii) providing periodic statements to its customers showing their
positions in the Institutional Shares; (iii) arranging for bank wires; (iv)
responding to routine customer inquiries relating to services performed by The
Ohio Company; (v) providing sub-accounting with respect to the Institutional
Shares beneficially owned by The Ohio Company'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)


                                      -36-
<PAGE>   99
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 Institutional 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 Ohio Company a monthly fee, computed
at the annual rate of .15% of the average aggregate net asset value of
Institutional Shares of that Fund held during the period by customers for whom
The Ohio Company has provided services under the Servicing Agreement. Any fees
paid by a Fund to Financial Institutions under the Services Plan will be borne
solely by the Institutional Shares of that Fund.

CUSTODIAN

         The Group has appointed The Fifth Third Bank ("Fifth Third"), 38
Fountain Square Plaza, Cincinnati, Ohio 45263, as the Funds' custodian. In such
capacity, Fifth Third will hold or arrange for the holding of all portfolio
securities and other assets acquired and owned by the Funds.

                      WHAT ARE MY RIGHTS AS A SHAREHOLDER?

         The Group was organized as an Ohio business trust on March 23, 1993.
The Group currently consists of six funds. The shares of each of the funds of
the Group, other than the two money market funds, Cardinal Government Securities
Money Market Fund ("CGSMMF") and Cardinal Tax Exempt Money Market Fund
("CTEMMF"), are currently offered in two separate classes: Investor A Shares,
otherwise referred to as Investor Shares, and Investor Y Shares, otherwise
referred to as Institutional Shares. CGSMMF and CTEMMF each only have one class
of shares. Each share represents an equal proportional 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.

         Shareholders are entitled to one vote for each dollar of value invested
and a proportionate fractional vote for any fraction of a dollar invested, and
will vote in the aggregate and not by series except as otherwise expressly
required by law. For example, shareholders of The Cardinal 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 accountants. However,
shareholders of The Cardinal Fund will vote as a fund, and not in the aggregate
with other shareholders of the Group, for purposes of approval of amendments to
the investment advisory agreement as it relates to The Cardinal Fund or any of
The Cardinal Fund's fundamental policies.

         Overall responsibility for the management of the Funds is vested in the
Board of Trustees of the Group. See "WHO MANAGES MY INVESTMENT OF THE FUNDS?"
Individual Trustees are elected by the shareholders of the Group, although
Trustees may under certain circumstances fill vacancies, including vacancies
created by expanding the size of the Board. Trustees 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 Ohio law. See "ADDITIONAL INFORMATION -
Miscellaneous" in the Statement of Additional Information for further
information.

         An annual or special meeting of shareholders to conduct necessary
business is not required by the Declaration of Trust, the 1940 Act or other
authority except, under certain circumstances, to elect Trustees, amend the
Declaration of Trust, approve the investment advisory agreement and to satisfy
certain other requirements. To the extent that such a meeting is not required,
the Group does not intend to have an annual or special meeting.

         The Group has represented to the Commission 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 and that the Group will
assist in communications with other shareholders as required by Section 16(c) of
the 1940 Act. At such 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 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
a 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 that 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 the Fund.

         Shareholders should direct all inquiries concerning such matters to the
Transfer Agent in writing to 215 East Capital Street, Columbus, Ohio 43215, or
by calling (800) 282-9446.

         Shareholders will receive unaudited semi-annual reports describing the
investment operations of the Funds and annual financial reports audited by
independent auditors.

INVESTMENT OBJECTIVES.......  The Fund seeks to maximize safety of capital and,
                              consistent with such objective, earn the highest
                              available current income obtainable from
                              government securities. (See pages 6 and 7.)
    

INVESTMENT POLICIES.........  Under normal market conditions, the Fund invests
                              substantially all but in no event less than 65% of
                              its total assets in obligations issued or
                              guaranteed by the U.S. Government, its agencies or
                              instrumentalities and repurchase agreements
                              secured by securities of the U.S. Government.
                              Under present market conditions, the Fund expects
                              to invest a substantial amount of its portfolio in
                              Ginnie Mae certificates. These investments entail
                              certain risks. (See pages 7 and 8.)

CURRENT INCOME..............  Dividends are declared daily and distributions are
                              generally made monthly as the Group shall
                              determine. Long-term capital gains, if any, are
                              distributed annually. (See page 14.)

   
RISK FACTORS AND SPECIAL
  CONSIDERATIONS............  An investment in a mutual fund such as the Fund
                              involves a certain amount of risk and may not be
                              suitable for all investors. Some investment
                              policies of the Fund may entail certain risks.
                              (See "WHAT ARE THE INVESTMENT OBJECTIVES AND
                              POLICIES OF THE FUND? -- Risk Factors and
                              Investment Techniques" on pages 8 through 10.)

PURCHASES...................  There is a minimum initial investment of $1,000
                              with subsequent minimums of $50. (See page 11.)
                              Purchases are made at the public offering price
                              which is equal to net asset value per share plus a
                              sales charge. This charge is equal to 4.50% of the
                              public offering price (4.71% of net amount
                              invested) reduced on investments of $100,000 or
                              more (see page 12).

REDEMPTIONS.................  Shares can be redeemed at net asset value per
                              share without charge if redeemed through the
                              Fund's distributor, The Ohio Company. (See page
                              14.)

  MANAGER...................  Cardinal Management Corp. (the "Adviser"), a
                              wholly-owned subsidiary of The Ohio Company, is
                              the Fund's investment adviser. The Adviser also

Additional Information.

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
   
From time to time the Fund may advertise its average annual total return,
cumulative return and/or yield. SUCH RETURN AND YIELD FIGURES ARE BASED UPON
HISTORICAL EARNINGS AND ARE NOT INTENDED TO INDICATE FUTURE PERFORMANCE. The
average annual total return advertised by the Fund refers to the return
generated by an investment in the Fund over certain specified periods since the
establishment of the Fund (including the term of CGOF's operations). The average
annual total return over a period equates the amount of an initial investment in
the Fund to the amount redeemable at the end of that period assuming that any
dividends and distributions earned by an investment in the Fund are immediately
reinvested and the maximum applicable sales charge, if any, is deducted from the
initial investment at the time of investment. Such figure is then annualized.
The cumulative return advertised refers to the total return on a hypothetical
investment over the relevant period and equates the amount of an initial
investment in the Fund to the amount redeemable at the end of that period
assuming that any dividends and distributions are immediately reinvested and the
maximum sales charge, if any, is deducted from the initial investment. Yield
will be computed by dividing the Fund's net investment 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. If the sales
charge were not deducted, the average annual total return, cumulative return and
yield advertised would be higher.
    
 
In addition, from time to time the Fund may include in its sales literature and
shareholder reports a quote of the current "distribution" rate for the Fund. A
distribution rate is simply a measure of the level of dividends distributed for
a specified period and is computed by dividing the total amount of dividends per
share paid by the Fund during the past 12 months by a current maximum offering
price. It differs from yield, which is a
 
                                                                               5

measure of the income actually earned by the Fund's investments, and from total
return, which is a measure of the income actually earned by, plus the effect of
any realized and unrealized appreciation or depreciation of, such investments
during a stated period. A distribution rate is, therefore, not intended to be a
complete measure of performance. A distribution rate may sometimes be greater
than yield since, for instance, it may include short-term and possibly long-term
gains (which may be non-recurring), may not include the effect of amortization
of bond premiums and does not reflect unrealized gains or losses.
 
   
Investors may also judge the performance of the Fund by comparing or referencing
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 such as those prepared by Dow Jones & Co., Inc.
and Standard & Poor's Corporation, and to data prepared by Lipper Analytical
Services, Inc. and Morningstar, Inc. Comparisons may also be made to indices or
data published in Money Magazine, Forbes, Barron's, The Wall Street Journal, The
New York Times, The Columbus Dispatch, Business Week, U.S.A. Today and Consumer
Reports. In addition to performance information, general information about the
Fund that appears in a publication such as those mentioned above may be included
in advertisements and in reports to shareholders.
    
 
   
Further information about the performance of the Fund is contained in an Annual
Report to Shareholders which may be obtained without charge by contacting the
Group at the telephone number set forth on the cover page of this Prospectus.
Performance quotations will be computed separately for Investor and
Institutional Shares. Because of differences in the fees and/or expenses borne
by Investor and Institutional Shares, the net yield and total return on each
class can be expected, at any given time, to differ from the net yield and total
return of the other class.

WHAT IS THE FUND?
- --------------------------------------------------------------------------------
 
The Fund is one separate diversified investment fund of the Group, which was
organized on March 23, 1993, as an Ohio business trust. The Group is registered
and operates as an open-end management investment company as defined in the
Investment Company Act of 1940, as amended (the "1940 Act"). The Fund was
organized for the purpose of acquiring all of the assets and liabilities of CGOF
to effect a reorganization of CGOF from a stand-alone investment company to a
separate series of the Group (the "Reorganization"). The Reorganization was
effected as of May 1, 1996.
 
The Fund is designed for individuals, corporations, fiduciaries, and
institutions who wish to invest for current income in a diversified,
professionally managed portfolio of securities issued by the U.S. Government and
securities directly guaranteed by the full faith and credit of the U.S.
Government -- without having to become involved in the detailed accounting and
safekeeping procedures normally associated with direct investment in these
securities.
 
- --------------------------------------------------------------------------------
WHAT ARE THE INVESTMENT OBJECTIVES AND POLICIES OF THE FUND?
- --------------------------------------------------------------------------------
 
IN GENERAL
 
The Fund's investment objectives are to maximize safety of capital and,
consistent with such objective, earn the highest available current income
obtainable from government securities. The current income earned from such
government securities may not be as great as the current income earned on lower
quality securities which have less liquidity and greater risk of nonpayment.
 
   
The Fund's investment objectives are a fundamental policy of the Fund, which
means that they may be changed only with the approval of a majority of the
outstanding Shares of the Fund (as defined below under "WHAT ARE MY RIGHTS AS A
SHAREHOLDER?"). There can be no assurance that the investment objectives of the
Fund will be achieved.
    
 
Under normal market conditions, the Fund will invest substantially all, but in
no event less than 65% of the value of its total assets, in obligations issued
or guaranteed by the U.S. Government or its agencies or
 
6
<PAGE>   113
 
instrumentalities ("U.S. Government Securities"). The Fund may also invest,
under normal market conditions, in the fixed income instruments described below
and in repurchase agreements. It may also engage in the options transactions
described below.
 
The Fund may, for daily cash management purposes, invest in high quality money
market securities and in repurchase agreements. In addition, the Fund may
invest, without limit, in any combination of U.S. Government Securities, money
market securities and repurchase agreements when, in the opinion of the Adviser,
it is determined that a temporary defensive position is warranted based upon
current market conditions. The Fund may also invest in securities of other
investment companies, as described more fully below.
 
The types of U.S. Government Securities invested in by the Fund will include
obligations issued by 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 ("Ginnie Mae") 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. The Fund will invest
in the obligations of such agencies or instrumentalities only when the Adviser
believes that the credit risk with respect thereto is minimal.
 
Certain securities held by the Fund may have mortgage obligations backing such
securities, including among others, conventional thirty year fixed rate mortgage
obligations, graduated payment mortgage obligations, fifteen year mortgage
obligations and adjustable rate mortgage obligations. All of these mortgage
obligations can be used to create pass-through securities. A pass-through
security is created when mortgage obligations are pooled together and undivided
interests in the pool or pools are sold. The cash flow from the mortgage
obligations is passed through to the holders of the securities in the form of
periodic payments of interest, principal and prepayments (net of a service fee).
Prepayments occur when the holder of an individual mortgage obligation prepays
the remaining principal before the mortgage obligation's scheduled maturity
date. As a result of the pass-through of prepayments of principal on the
underlying securities, mortgage-backed securities are often subject to more
rapid prepayment of principal than their stated maturity would indicate. Because
the prepayment characteristics of the underlying mortgage obligations vary, it
is not possible to predict accurately the realized yield or average life of a
particular issue of pass-through certificates. Prepayment rates are important
because of their effect on the yield and price of the securities. Accelerated
prepayments have an adverse impact on yields for pass-through certificates
purchased at a premium (i.e., a price in excess of principal amount) and may
involve additional risk of loss of principal because the premium may not have
been fully amortized at the time the obligation is repaid. The opposite is true
for pass-through certificates purchased at a discount. The Fund may purchase
mortgage-related securities at a premium or at a discount. Reinvestment of
principal payments may occur at higher or lower rates than the original yield on
such securities. Due to the prepayment feature and the need to reinvest payments
and prepayments of principal at current rates, mortgage-related securities can
be less effective than typical bonds of similar maturities at maintaining yields
during periods of declining interest rates.
 
Certain debt securities such as, but not limited to, mortgage backed securities,
as well as other securities subject to prepayment of principal prior to the
stated maturity date, are expected to be repaid prior to their stated maturity
dates. As a result, the effective maturity of these securities is expected to be
shorter than the stated maturity. For purposes of calculating the Fund's
weighted average portfolio maturity, the effective maturity of such securities
will be used.
 
                                                                               7
<PAGE>   114
 
Under present market conditions, the Fund expects to invest a substantial amount
of its portfolio in Ginnie Mae certificates, which are mortgage-backed
securities representing part ownership in a specific pool of mortgage loans
insured by the Federal Housing Administration or Farmers Home Administration or
guaranteed by the Veterans Administration. Should market or economic conditions
warrant, this practice may be changed at the discretion of the Adviser. Ginnie
Mae guarantees the timely payment of monthly installments of principal and
interest on its certificates, when due, whether or not payments are received on
the underlying mortgage loans, and the full faith and credit of the United
States is pledged to the timely payment by Ginnie Mae of such principal and
interest.
 
Although the mortgage loans in the pool underlying a Ginnie Mae certificate will
have maturities of up to thirty years, the actual average life of the Ginnie Mae
certificates typically will be substantially less because the mortgage loans
will be subject to normal principal amortization and may be prepaid prior to
maturity. Prepayment rates vary widely and may be affected by changes in market
interest rates and general economic conditions. In periods of falling interest
rates, the rate of prepayment tends to increase, thereby shortening the actual
average life of the Ginnie Mae certificates 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 actual average life of the Ginnie Mae certificates and extending the period
of time over which income at the lower rates is received. Accordingly, it is not
possible to accurately predict the average life of a particular pool. Standard
practice is to treat Ginnie Mae certificates as having effective maturities of
twelve years. Reinvestment of principal payments may occur at higher or lower
rates than the original yield on the certificates. Due to the prepayment feature
and the need to reinvest payments and prepayments of principal at current rates,
Ginnie Mae certificates can be less effective than typical bonds of similar
maturities at maintaining yields during periods of declining interest rates.
 
RISK FACTORS AND INVESTMENT TECHNIQUES
 
GENERAL. Like any investment program, an investment in the Fund entails certain
risks. The value of the Fund's portfolio securities, and therefore the Fund's
net asset value per share, may increase or decrease due to various factors,
principally changes in prevailing interest rates. Generally, a rise in interest
rates will result in a decrease in the Fund's net asset value per share, while a
drop in interest rates will result in an increase in the Fund's net asset value
per share.
 
The Fund may invest in put and call options and futures, as described below.
Such instruments are considered to be "derivatives." A derivative is generally
defined as an instrument whose value is based upon, or derived from, some
underlying index, reference rate (e.g., interest rates), security, commodity or
other asset. The Fund will not invest more than 10% of its total assets in such
derivatives at any one time.
 
REPURCHASE AGREEMENTS. Securities held by the Fund may be subject to repurchase
agreements. Under the terms of the repurchase agreement, the Fund would acquire
securities from a financial institution such as a well-established securities
dealer or a bank which is a member of the Federal Reserve System which the
Adviser deems creditworthy under guidelines approved by the Group's Board of
Trustees. At the time of purchase, the bank or securities dealer agrees to
repurchase the underlying securities from the Fund at a specified time and
price. The resale price reflects the purchase price plus an agreed upon market
rate of interest which is unrelated to the coupon rate or maturity of the
underlying security. The Fund will only enter into a repurchase agreement where
(i) the underlying securities are of the type which the Fund's investment
policies would allow it to purchase directly, (ii) the market value of the
underlying security, including interest accrued, will be at all times equal to
or exceed the value of the repurchase agreement, and (iii) payment for the
underlying securities is made only upon physical delivery or evidence of book-
entry transfer to the account of the Fund's custodian or a bank acting as agent.
The Adviser will be responsible for continuously monitoring such requirements.
 
WHEN-ISSUED AND DELAYED-DELIVERY TRANSACTIONS. The Fund may also purchase
securities on a when-issued or delayed-delivery basis. The Fund will engage in
when-issued and delayed-delivery transactions
 
8
<PAGE>   115
 
only for the purpose of acquiring portfolio securities consistent with its
investment objectives and policies, not for investment leverage, although such
transactions represent a form of leveraging. 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. The Fund will not pay for such securities or start earning interest on
them until they are received. When the Fund agrees to purchase such securities,
its 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, the Fund relies on the seller to complete the
transaction; the seller's failure to do so may cause the Fund to miss a price or
yield considered to be advantageous.
 
The Fund's commitments to purchase when-issued securities will not exceed 25% of
the value of its total assets absent unusual market conditions. In the event
that its commitments to purchase when-issued securities ever exceed 25% of the
value of its assets, the Fund's liquidity and the ability of the Adviser to
manage it might be adversely affected.
 
PUT AND CALL OPTIONS. Subject to its investment policies and for purposes of
hedging against market risks related to its portfolio securities, the Fund may
purchase put and call options on securities. Purchasing options is a specialized
investment technique that entails a substantial risk of a complete loss of the
amounts paid as premiums to writers of options. The Fund will purchase put
options only on securities in which the Fund may otherwise invest. The Fund may
also engage in writing call options from time to time as the Adviser deems
appropriate. The Fund will write only covered call options (options on
securities owned by the Fund). In order to close out a call option it has
written, the Fund will 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 has written. When a
portfolio security subject to a call option is sold, the Fund will effect a
closing purchase transaction to close out any existing call option on that
security. If the 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 market
conditions, it is not expected that the underlying value of portfolio securities
subject to such options would exceed 25% of the net assets of the Fund.
 
The Fund, as part of its option transactions, also may purchase index put and
call options and write index options. As with options on individual securities,
the Fund will write only covered index call options. Through the writing or
purchase of index options the Fund can achieve many of the same objectives as
through the use of options on individual securities. Options on securities
indices are similar to options on a security except that, rather than the right
to take or make delivery of a security at a specified price, an option on a
securities index gives the holder the right to receive, upon exercise of the
option, an amount of cash if the closing level of the securities index upon
which the option is based is greater than, in the case of a call, or less than,
in the case of a put, the exercise price of the option.
 
Price movements in securities which the Fund owns or intends to purchase
probably will not correlate perfectly with movements in the level of an index
and, therefore, the Fund bears the risk of a loss on an index option that is not
completely offset by movements in the price of such securities. Because index
options are settled in cash, a call writer cannot determine the amount of its
settlement obligations in advance and, unlike call writing on specific
securities, cannot provide in advance for, or cover, its potential settlement
obligations by acquiring and holding the underlying securities. The Fund may be
required to segregate assets or provide an initial margin to cover index options
that would require it to pay cash upon exercise.
 
FUTURES CONTRACTS. The Fund may also enter into contracts for the future
delivery of securities and futures contracts based on a specific security, class
of securities or an index, purchase or sell options on any such futures
contracts and engage in related closing transactions. A futures contract on a
securities index is an
 
                                                                               9
<PAGE>   116
 
agreement obligating either party to pay, and entitling the other party to
receive, while the contract is outstanding, cash payments based on the level of
a specified securities index.
 
The Fund may engage in such futures contracts in an effort to hedge against
market risks. For example, when interest rates are expected to rise or market
values of portfolio securities are expected to fall, the Fund can seek through
the sale of futures contracts to offset a decline in the value of its portfolio
securities. When interest rates are expected to fall or market values are
expected to rise, the Fund, through the purchase of such contracts, can attempt
to secure better rates or prices for the Fund than might later be available in
the market when it effects anticipated purchases.
 
The acquisition of put and call options on futures contracts will, respectively,
give the Fund the right (but not the obligation), for a specified price, to sell
or to purchase the underlying futures contract, upon exercise of the option, at
any time during the option period.
 
Aggregate initial margin deposits for futures contracts, and premiums paid for
related options, may not exceed five percent of the Fund's total assets, and the
value of securities that are the subject of such futures and options (both for
receipt and delivery) may not exceed one-third of the market value of the Fund's
total assets. Futures transactions will be limited to the extent necessary to
maintain the Fund's qualification as a regulated investment company.
 
Futures transactions involve brokerage costs and require the Fund to segregate
assets to cover contracts that would require it to purchase securities. The Fund
may lose the expected benefit of futures transactions if interest rates or
securities prices move in an unanticipated manner. Such unanticipated changes
may also result in poorer overall performance than if the Fund had not entered
into any futures transactions. In addition, the value of the Fund's futures
positions may not prove to be perfectly or even highly correlated with the value
of its portfolio securities, limiting the Fund's ability to hedge effectively
against interest rate and/or market risk and giving rise to additional risks.
There is no assurance of liquidity in the secondary market for purposes of
closing out futures positions.
 
INVESTMENT COMPANY SECURITIES. The Fund may also invest up to 10% of the value
of its total assets in the securities of other investment companies subject to
the limitations set forth in the 1940 Act. The Fund intends to invest in the
securities of other investment companies which, in the opinion of the Adviser,
will assist the Fund in achieving its objectives and in money market mutual
funds for purposes of short-term cash management. The Fund's investment in such
other investment companies may result in the duplication of fees and expenses,
particularly investment advisory fees. For a further discussion of the
limitations on the Fund's investments in other investment companies, see
"INVESTMENT OBJECTIVES AND POLICIES -- Additional Information on Portfolio
Instruments -- Securities of Other Investment Companies" in the Fund's Statement
of Additional Information.
 
INVESTMENT RESTRICTIONS
 
The 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 the Fund (as defined
below under "WHAT ARE MY RIGHTS AS A SHAREHOLDER?").
 
The 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, more than 5% of the value of the
        Fund's total assets would be invested in such issuer, or the Fund would
        hold more than 10% of the outstanding voting securities of the issuer,
        except that up to 25% of the value of the Fund's total assets may be
        invested without regard to such limitations. There is no limit to the
        percentage of assets that may be invested in U.S. Treasury bills, notes,
        or other obligations issued or guaranteed by the U.S. Government or its
        agencies or instrumentalities.
 
10
<PAGE>   117
 
     2. 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) 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.
 
     3. Borrow money or issue senior securities, except that the Fund may borrow
        from banks or enter into reverse repurchase agreements or dollar roll
        agreements for temporary purposes in amounts up to 10% of the value of
        its total assets at the time of such borrowing and except as permitted
        pursuant to an exemption from the 1940 Act. The Fund will not purchase
        securities while its borrowings (including reverse repurchase agreements
        and dollar roll agreements) exceed 5% of its total assets.
 
     4. Make loans, except that the Fund may purchase or hold debt instruments
        and lend portfolio securities in accordance with its investment
        objectives and policies, make time deposits with financial institutions
        and enter into repurchase agreements.
 
   
The following additional investment restriction may be changed without the vote
of a majority of the outstanding Shares of the Fund. The Fund shall not:
    
 
     1. Purchase or otherwise acquire any securities, if as a result, more than
15% of the Fund's net assets would be invested in securities that are illiquid.

The above charges on investments of $100,000 or more are applicable to purchases
made at one time by an individual, or an individual, his spouse and their
children not of legal age, or a trustee, guardian or other like fiduciary of
certain single trust estates or certain single fiduciary accounts.
 
   
No sales charge is imposed on purchases of Shares by (1) officers, trustees, and
employees of the Group, or (2) full-time employees of The Ohio Company or the
Adviser who have been such for at least 90 days or by qualified retirement plans
for such persons. The Ohio Company may change or eliminate the foregoing waivers
at any time. The Ohio Company may also periodically waive all or a portion of
the sales charge for all investors with respect to the Fund.
    
 
From time to time, The Ohio Company, from its own resources, may also provide
additional compensation to securities dealers in connection with sales of shares
of the Cardinal Funds. Such compensation will include financial assistance to
securities dealers in connection with conferences, sales or training programs
for their employees, seminars for the public, advertising, sales campaigns
and/or shareholder services and programs regarding one or more of the Cardinal
Funds and other dealer-sponsored programs or events. In some instances, this
compensation may be made available only to certain securities dealers whose
representatives have sold or are expected to sell significant amounts of shares
of the Cardinal Funds. Compensation will 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. Securities
dealers may not use sales of the Fund's Shares to qualify for this compensation
to the extent such may be prohibited by the laws of any state or any
self-regulatory agency, such as the National Association of Securities Dealers,
Inc. In addition, The Ohio Company may make ongoing payments to brokerage firms,
financial institutions (including banks) and others to facilitate the
administration and servicing of shareholder accounts. None of the aforementioned
additional compensation is paid for by the Fund or its shareholders.
 
AUTOMATIC INVESTMENT PLAN
 
The Fund has made arrangements to enable you to make automatic monthly or
quarterly investments, in the minimum amount of $50 per transaction, from your
checking account. Assuming the cooperation of your financial institution, your
checking account therein will be debited to purchase Investor Shares of the Fund
on the periodic basis you select. Confirmation of your purchase of the Fund's
Investor Shares will be provided by the Transfer Agent. The debit of your
checking account will be reflected in the checking

The Ohio Company for the appropriate form.
 
- --------------------------------------------------------------------------------
HOW MAY I QUALIFY FOR QUANTITY DISCOUNTS?
- --------------------------------------------------------------------------------
 
LETTER OF INTENTION
 
   
If you (including your spouse and children not of legal age) intend to purchase
$100,000 or more of Investor Shares of the Fund and of Investor Shares of any
other Cardinal Fund sold with a sales charge (a "Cardinal Load Fund") during any
13-month period you may sign a letter of intention to that effect obtained from
The Ohio Company and pay the reduced sales charge applicable to the total amount
of Investor Shares to be so purchased. The 13-month period during which the
Letter of Intention is in effect will begin on the date of the earliest purchase
to be included. In addition, trustees, guardians or other like fiduciaries of
single trust estates or certain single fiduciary accounts may take advantage of
the quantity discounts pursuant to a letter of intention.
    
 
A letter of intention is not a binding obligation upon you to purchase the full
amount indicated. Investor Shares purchased with the first 5% of such amount
will be held in escrow (while remaining registered in your name) to secure
payment of the higher sales charge applicable to the Investor Shares actually
purchased. If the full amount indicated is not purchased, such escrowed Investor
Shares will be involuntarily redeemed to pay the additional sales charge, if
necessary. Dividends on escrowed Investor Shares, whether paid in cash or
reinvested in additional Investor Shares of the applicable Cardinal Load Fund,
are not subject to escrow. The escrowed Investor Shares will not be available
for disposal by you until all purchases pursuant to the Letter of Intention have
been made or the higher sales charge has been paid. When the full amount
indicated has been purchased, the escrow will be released. To the extent that
you purchase more than the dollar amount indicated on the Letter of Intention
and qualify for a further reduced sales charge, the sales charge will be
adjusted for the entire amount purchased at the end of the 13-month period. The
difference in sales charge will be, as you instruct, either delivered to you in
cash or used to purchase additional Investor Shares of the Cardinal Load Fund
designated by you subject to the rate of sales charge applicable to the actual
amount of the aggregate purchases. This program, however, may be modified or
eliminated at any time or from time to time by the Group without notice.
 
CONCURRENT PURCHASES
 
For purposes of qualifying for a lower sales charge, you have the privilege of
combining "concurrent purchases" of Investor Shares of the Fund and of one or
more of the other Cardinal Load Funds. For example, if you concurrently purchase
Investor Shares of the Fund at the total public offering price of $50,000 and
Investor Shares of another Cardinal Load Fund at the total public offering price
of $50,000, the sales charge paid by you would be that applicable to a $100,000
purchase as shown in the table above. "Concurrent purchases," as described
above, shall include the combined purchases of Investor Shares of you, your
spouse and your children not of legal age. To receive the applicable public
offering price pursuant to this privilege, you must, at the time of purchase,
give The Ohio Company sufficient information to permit confirmation of
qualification. This privilege, however, may be modified or eliminated at any
time or from time to time by the Group without notice thereof.
 
RIGHTS OF ACCUMULATION
 
After your initial purchase of Investor Shares you may also be eligible to pay a
reduced sales charge for your subsequent purchases of Investor Shares where the
total public offering price of Investor Shares then being purchased plus the
then aggregate current net asset value of Investor Shares of the Fund and of
Investor Shares of any Cardinal Load Fund held in your account equals $100,000
or more. You would be able to purchase Investor Shares at the public offering
price applicable to the total of (a) the total public offering price of the
Investor Shares of the Fund then being purchased plus (b) the then current net
asset value of Investor Shares of the Fund and of Investor Shares of any other
Cardinal Load Fund held in your account.

 
                                                                              13
<PAGE>   120
 
   
For purposes of determining the aggregate current net asset value of Investor
Shares held in your account, you may include Investor Shares then owned by your
spouse and children not of legal age.
    
 
You may obtain additional information about the foregoing special purchase
method from The Ohio Company. You are responsible for notifying The Ohio Company
at the time of purchase when purchases may be accumulated to take advantage of
the reduced sales charge. This program, however, may be modified or eliminated
at any time or from time to time by the Group without notice thereof.
 
- --------------------------------------------------------------------------------
WHAT DISTRIBUTIONS WILL I RECEIVE?
- --------------------------------------------------------------------------------
 
   
A dividend consisting of net income is declared daily to Shareholders of the
Fund at the close of business on the day of declaration, and such dividends are
generally paid monthly. Dividends consisting of long-term capital gains normally
will be distributed only once annually. Dividends and distributions will be paid
only in additional Investor Shares and not in cash; except, however, that for
dividends and distributions of $10 or more, a shareholder may specifically
request that such amounts be paid to him in cash. Dividends are paid in cash not
later than seven days after a shareholder's complete redemption of his Investor
Shares in the Fund.
    
 
   
The Fund's net investment income available for distribution to the holders of
Investor Shares will be reduced by the amount of Rule 12b-1 fees paid out under
the Plan described below.
    
 
Shareholders may also elect to receive dividends and distributions in cash by
using ACH processing as described under "WHAT OTHER SHAREHOLDER PROGRAMS ARE
PROVIDED? - ACH Processing" below.
 
- --------------------------------------------------------------------------------
HOW MAY I REDEEM MY INVESTOR SHARES?
- --------------------------------------------------------------------------------
 
Investors may redeem Investor Shares of the Fund on any Business Day at the net
asset value per Investor Share next determined following the receipt by the
Transfer Agent, 215 East Capital Street, Columbus, Ohio 43215, of written or
telephonic notice to redeem, as described more fully below. See "HOW IS NET
ASSET VALUE CALCULATED?", below, for a description of when net asset value is
determined.
 
As requested, The Ohio Company, on behalf of a shareholder, will forward the
foregoing notice to redeem to the Transfer Agent without charge. Other
broker-dealers may assist a shareholder in redeeming his Investor Shares and may
charge a fee for such services.
 
The Group will make payment for redeemed Investor Shares as promptly as
practicable but in no event more than seven days after receipt by the Transfer
Agent of the foregoing notice. The Group reserves the right to delay payment for
the redemption of Investor Shares where such Investor Shares were purchased with
other than immediately available funds, but only until the purchase payment has
cleared (which may take fifteen or more days from the date the purchase payment
is received by the Fund). The purchase of Investor Shares by wire transfer of
federal funds would avoid any such delay.
 
The Group intends to pay cash for all Investor Shares redeemed, but, under
abnormal conditions which make payment in cash unwise, the Group may make
payment wholly or partly in readily marketable portfolio securities at their
then market value equal to the redemption price. In such cases, an investor may
incur brokerage costs in converting such securities to cash.
 
The Group may suspend the right of redemption or may delay payment during any
period the determination of net asset value is suspended. See "HOW IS NET ASSET
VALUE CALCULATED?".
 
Due to the high cost of maintaining accounts, the Group reserves the right to
redeem, at net asset value, involuntarily Shares in any account at the then
current net asset value if at any time redemptions (but not as a result of a
decrease in the market price of such Shares or the deduction of any sales
charge) have reduced a shareholder's total investment in the Fund to a net asset
value below $500. A shareholder will be notified in writing that the value of
Fund Shares in the account is less than $500 and allowed not less than 30 days
to
 
14
<PAGE>   121
 
increase his investment in the Fund to $500 before the redemption is processed.
Proceeds of redemptions so processed, including dividends declared to the date
of redemption, will be promptly paid to the shareholder.
 
REDEMPTION BY MAIL
 
   
Shareholders may redeem Investor Shares of the Fund by submitting a written
request therefor to the Transfer Agent, at 215 East Capital Street, Columbus,
Ohio 43215. The Transfer Agent will request a signature guarantee by an eligible
guarantor institution as described below. However, a signature guarantee will
not be required if (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, provided, however, that the address of record has not been
changed within the preceding 15 days. For purposes of this policy, an "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 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 or (2) it has reason
to believe that the transaction would otherwise be improper.
    
 
REDEMPTION BY TELEPHONE
 
   
Shareholders may redeem Investor Shares of the Fund by calling the Group at the
telephone number set forth on the front of this Prospectus. The shareholder may
direct that the redemption proceeds be mailed to the address of record.
    
 
Neither the Group, the Fund nor its service providers will be liable for any
loss, damages, expense or cost arising out of any telephone redemption effected
in accordance with the Group's telephone redemption procedures, acting upon
instructions reasonably believed to be genuine. The Group will employ procedures
designed to provide reasonable assurances that instructions by telephone are
genuine; if these procedures are not followed, the Group, the Fund or its
service providers may be liable for any losses due to unauthorized or fraudulent
instructions. These procedures may include recording all phone conversations,
sending confirmations to shareholders within 72 hours of the telephone
transaction, and verification of account name and account number or tax
identification number. If, due to temporary adverse conditions, investors are
unable to effect telephone transactions, shareholders may also redeem their
Investor Shares by mail as described above.
 
AUTOMATIC WITHDRAWAL
 
Shareholders may elect to have the proceeds from redemptions of Shares
transmitted to an authorized bank account at a Federal Reserve member bank
through ACH processing as described under "WHAT OTHER SHAREHOLDER PROGRAMS ARE
PROVIDED? - ACH Processing" below.
 
SYSTEMATIC WITHDRAWAL PLAN
 
   
If you are the owner of Investor Shares of the Fund having a total value of
$25,000 or more at the current net asset value, you may elect to redeem your
Investor Shares monthly or quarterly in amounts of $50 or more, pursuant to the
Fund's Systematic Withdrawal Plan. Please contact The Ohio Company for the
appropriate form. Purchase of additional Investor Shares, using the Automatic
Investment Plan described above, concurrent with withdrawals may be
disadvantageous to certain shareholders because of tax liabilities and sales
charges.
    
 
                                                                              15
<PAGE>   122
 
- --------------------------------------------------------------------------------
WHAT OTHER SHAREHOLDER PROGRAMS ARE PROVIDED?
- --------------------------------------------------------------------------------
 
ACH PROCESSING
 
   
The Fund offers ACH privileges. Investors may use ACH processing to make
subsequent purchases, redeem Shares and/or electronically transfer distributions
paid on Shares, in addition to the other methods described in this Prospectus.
ACH provides a method by which funds may be automatically transferred to or from
an authorized bank account at a Federal Reserve member bank that is an ACH
member. Please contact your representative if you are interested in ACH
processing.
    
 
EXCHANGE PRIVILEGE
 
   
Holders of Investor Shares of the Fund may, provided the amount to be exchanged
meets the applicable minimum investment requirements and the exchange is made in
states where it is legally authorized, exchange, at respective net asset values,
Investor Shares of the Fund for:
    
 
   
    Investor Shares of Cardinal Aggressive Growth Fund,
    an equity fund seeking appreciation of
    capital (upon the payment of the applicable sales charge);
    
 
   
    Investor Shares of Cardinal Balanced Fund,
    a fund seeking current income and long-term
    growth of both capital and income (upon
    the payment of the applicable sales charge);
    
 
   
    Investor Shares of The Cardinal Fund,
    an equity fund seeking long-term growth
    of capital and income (upon the payment of
    the applicable sales charge);
    
 
   
    Shares of Cardinal Government Securities Money Market Fund,
    a U.S. Government securities money market fund
    (without payment of any sales charge); or
    
 
   
    Shares of Cardinal Tax Exempt Money Market Fund,
    a tax-free money market fund
    (without payment of any sales charge).
    
 
   
Notwithstanding the foregoing and subject to the limitations contained in the
following paragraph, (i) exchanges by holders of Investor Shares, for whom the
sales charge has been waived, for Investor Shares of a Cardinal Load Fund may be
completed without the payment of a sales charge, and (ii) exchanges of Investor
Shares by all other shareholders for Investor Shares of a Cardinal Load Fund may
be completed upon the payment of a sales charge equal to the difference, if any,
between the sales charge payable upon purchase of Investor Shares of such
Cardinal Load Fund and the sales charge previously paid on the Investor Shares
to be exchanged.
    
 
   
The foregoing exchange privilege must be made by written or telephonic
authorization. A shareholder should notify The Ohio Company of his desire to
make an exchange, and The Ohio Company will furnish, as necessary, a prospectus
and an application form to open the account. The Transfer Agent will require
that any written authorization of an exchange include a signature guarantee as
described above under "HOW MAY I REDEEM MY SHARES? -- Redemption by mail."
However, a signature guarantee will not be required if the exchange requested is
within the same account or into an existing account of the shareholder held in
the same name or names and in the same capacity as the account from which the
exchange is to be made. Shareholders may also authorize an exchange of Shares of
the Fund by telephone. Neither the Group, the Fund nor any of its service
providers will be liable for any loss, damages, expense or
    
 
16
<PAGE>   123
 
cost arising out of any telephone exchange authorization to the extent and
subject to the requirements set forth under "HOW MAY I REDEEM MY SHARES? --
Redemption by telephone" above.
 
   
For tax purposes, an exchange is treated as a redemption and a new purchase.
However, a shareholder may not include any sales charge on Investor Shares of
the Fund for purposes of calculating the gain or loss realized upon an exchange
of those Investor Shares within 90 days of their purchase.
    
 
The Group may, at any time, modify or terminate the foregoing exchange
privilege. The Group, however, will give shareholders of the Fund 60 days'
advance written notice of any such modification or termination.
 
- --------------------------------------------------------------------------------
HOW IS NET ASSET VALUE CALCULATED?
- --------------------------------------------------------------------------------
 
   
The net asset value of the Fund is determined once daily as of 4:00 P.M. Eastern
Time, on each Business Day. A "Business Day" is a day on which the New York
Stock Exchange is open for business and any other day (other than a day on which
no Shares of the Fund are tendered for redemption and no order to purchase any
Shares of the Fund is received) during which there is a sufficient degree of
trading in the Fund's portfolio securities that the net asset value might be
materially affected by changes in the value of the portfolio securities. The net
asset value per share of each class of the Fund is computed by dividing the sum
of the value of the Fund's portfolio securities plus any cash and other assets
(including interest and dividends accrued but not received) allocable to such
class minus all liabilities (including estimated accrued expenses) allocable to
such class by the total number of Shares of that class then outstanding.
    
 
The net asset value per share will fluctuate as the value of the investment
portfolio of the Fund changes.
 
Portfolio securities for which over-the-counter market quotations are readily
available are valued at the bid price. The Fund uses one or more pricing
services to provide such market quotations. Securities and other assets for
which market quotations are not readily available are valued at fair value as
determined in good faith by or under the direction of the Board of Trustees of
the Group.
 
Determination of the net asset value may be suspended at times when (a) trading
on the New York Stock Exchange is restricted by applicable rules and regulations
of the Commission, (b) the New York Stock Exchange is closed for other than
customary weekend and holiday closings, (c) an emergency exists as a result of
which disposal by the Group of portfolio securities owned by the Fund or
valuation of net assets of the Fund is not reasonably practicable, or (d) the
Commission has by order permitted such suspension.
 
- --------------------------------------------------------------------------------
DOES THE FUND PAY FEDERAL INCOME TAX?
- --------------------------------------------------------------------------------
 
Each of the funds of the Group, including the Fund, is treated as a separate
entity for federal income tax purposes and intends to qualify as a "regulated
investment company" under the Code for so long as such qualification is in the
best interest of that fund's shareholders. Qualification as a regulated
investment company under the Code requires, among other things, that the
regulated investment company distribute to its shareholders at least 90% of its
investment company taxable income. The Fund contemplates declaring as dividends
100% of the Fund's investment company taxable income (before deduction of
dividends paid).
 
A non-deductible 4% excise tax is imposed on regulated investment companies that
do not distribute in each calendar year (regardless of whether they otherwise
have a non-calendar taxable year) an amount equal to 98% of their ordinary
income for the calendar year plus 98% of their capital gain net income for the
one-year period ending on October 31 of such calendar year. The balance of such
income must be distributed during the next calendar year. If distributions
during a calendar year were less than the required amount, the Fund would be
subject to a nondeductible excise tax equal to 4% of the deficiency.
 
                                                                              17
<PAGE>   124
 
- --------------------------------------------------------------------------------
WHAT ABOUT MY TAXES?
- --------------------------------------------------------------------------------
 
   
It is expected that the Fund will distribute annually to shareholders all or
substantially all of the Fund's net ordinary income and net realized capital
gains and that such distributed net ordinary income and distributed net realized
capital gains will be taxable income to shareholders for federal income tax
purposes, even if paid in additional Shares of the Fund and not in cash. Since
all of the Fund's net investment income is expected to be derived from earned
interest and short-term capital gains, it is anticipated that no part of any
distribution will be eligible for the dividends received deduction for
corporations.
    
 
   
Distribution by the Fund of the excess of net long-term capital gain over net
short-term capital loss is taxable to shareholders as long-term capital gain in
the year in which it is received, regardless of how long the shareholder has
held the Shares. Such distributions are not eligible for the dividends received
deduction.
    
 
If the net asset value of a Share is reduced below the shareholder's cost of
that Share by the distribution of income or gain realized on the sale of
securities, the distribution is a return of invested principal, although taxable
as described above.
 
Prior to purchasing Shares, the impact of dividends or capital gains
distributions which are expected to be declared or have been declared, but have
not been paid, should be carefully considered. Any such dividends or capital
gains distributions paid shortly after a purchase of Shares prior to the record
date will have the effect of reducing the per share net asset value of the
Shares by the amount of the dividends or distributions. All or a portion of such
dividends or distributions, although in effect a return of capital, is subject
to tax.
 
The foregoing is intended only as a brief summary of some of the important tax
considerations generally affecting the Fund and its shareholders. Potential
investors in the Fund are urged to consult their tax advisers concerning the
application of federal, state and local taxes as such laws and regulations
affect their own tax situation.
 
The Transfer Agent will inform shareholders at least annually of the amount and
nature of such income and capital gains.
 
- --------------------------------------------------------------------------------
WHO MANAGES MY INVESTMENT IN THE FUND?
- --------------------------------------------------------------------------------
 
   
Except where shareholder action is required by law, all of the authority of the
Group is exercised under the direction of the Group's Trustees. Unless so
required by the Group's Declaration of Trust or By-Laws or by Ohio law, at any
given time all of the Trustees may not have been elected by the shareholders of
the Group. The Trustees are empowered to elect officers and contract with and
provide for the compensation of agents, consultants and other professionals to
assist and advise it in its day-to-day operations. The Group will be managed in
accordance with its Declaration of Trust and the laws of Ohio governing business
trusts.
    
 
   
The Trustees of the Group 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 the Adviser or The Ohio Company receives any compensation
from the Group for acting as a Trustee of the Group. The officers of the Group
receive no compensation directly from the Group for performing the duties of
their offices. The Adviser receives fees from the Group for acting as investment
adviser and manager and as dividend and transfer agent and for providing certain
fund accounting services. The Ohio Company receives no fees under its
Distribution Agreement with the Group but, with respect to Investor Shares only,
may retain all or a portion of the sales charge and receives fees under the
Distribution Plan discussed below.

<PAGE>   125
 
INVESTMENT ADVISER AND MANAGER
 
   
Cardinal Management Corp. (the "Adviser"), 155 East Broad Street, Columbus, Ohio
43215, a wholly owned subsidiary of The Ohio Company, is the investment adviser
and manager of the Fund. The Adviser is also the investment adviser and manager
of each of the other Cardinal Funds.
    
 
   
The Ohio Company, an investment banking firm organized in 1925, is a member of
the New York and Chicago Stock Exchanges, other regional stock exchanges and the
National Association of Securities Dealers, Inc. Descendants of H.P. and R.F.
Wolfe, deceased, and members of their families, through their possession of a
majority of voting stock, may be considered controlling persons of The Ohio
Company. The Ohio Company serves as principal underwriter for each of the
Cardinal Funds.
    
 
In its capacity as investment adviser, and subject to the ultimate authority of
the Group's Board of Trustees, the Adviser, in accordance with the Fund's
investment objectives and policies, manages the Fund, and makes decisions with
respect to and places orders for all purchases and sales of its portfolio
securities. Since the inception of CGOF (the Fund's predecessor) and since the
Reorganization with respect to the Fund, John R. Carle has been primarily
responsible for the day-to-day management of such Funds' portfolios. Mr. Carle
has been a portfolio manager with the Adviser and/or The Ohio Company since
1971. In addition, pursuant to the Investment Advisory Agreement, the Adviser
generally assists in all aspects of the Fund's administration and operation.
 
For the services provided and expenses assumed pursuant to its investment
advisory agreement with the Group with respect to the Fund, the Adviser receives
a fee from the Fund, computed daily and paid monthly at the annual rate of .50%
of average net daily assets of the Fund. The Adviser may, however, periodically
waive all or a portion of its advisory fee with respect to the Fund to increase
the net income of the Fund available for distribution as dividends. The waiver
of such fee will cause the yield of the Fund to be higher than it would
otherwise be in the absence of such a waiver.
 
DIVIDEND AND TRANSFER AGENT AND FUND ACCOUNTANT
 
The Group has entered into a Transfer Agency and Fund Accounting Agreement with
Cardinal Management Corp. (the "Transfer Agent"), 215 East Capital Street,
Columbus, Ohio 43215, pursuant to which the Transfer Agent has agreed to act as
the Fund's transfer agent and dividend disbursing agent. In consideration of
such services, the Fund has agreed to pay the Transfer Agent an annual fee, paid
monthly, equal to $21 per shareholder account plus out-of-pocket expenses. In
addition, the Transfer Agent provides certain fund accounting services for the
Fund. The Transfer Agent receives a fee from the Fund for such services equal to
a fee computed daily and paid periodically at an annual rate of .03% of the
Fund's average daily net assets of up to $100 million and .01% of the Fund's
average daily net assets in excess of $100 million.
 
DISTRIBUTOR
 
The Group has entered into a Distributor's Contract with The Ohio Company, 155
East Broad Street, Columbus, Ohio 43215, pursuant to which Shares of the Fund
will be offered continuously on a best efforts basis by The Ohio Company and
dealers selected by The Ohio Company. H. Keith Allen is an officer and trustee
of the Group and an officer and director of The Ohio Company. Frank W. Siegel is
an officer and trustee of the Group and an officer of The Ohio Company. James M.
Schrack II is an officer of both the Group and The Ohio Company.
 
EXPENSES
 
   
The Adviser bears all expenses in connection with the performance of its
services as investment adviser, manager, transfer agent and fund accountant
other than the cost of securities (including brokerage commissions, if any)
purchased for the Fund. The Trustees reserve the right to allocate certain other
expenses, which can reasonably be identified as relating to a particular class,
solely to such class, including Investor Shares, as they deem appropriate
("Class Expenses"). Such expenses include (a) transfer agency
    
 
                                                                              19
<PAGE>   126
 
   
fees identified as being attributable to a specific class; (b) printing and
postage expenses related to preparing and distributing materials such as
shareholder reports, prospectuses and proxy statements to current shareholders
of a specific class; (c) Blue Sky registration fees incurred by a class of
shares; (d) SEC registration fees incurred by a class; (e) expenses of
administrative personnel and services as required to support the shareholders of
a specific class; (f) litigation or other legal expenses and audit or other
accounting expenses relating solely to one class; (g) trustees' fees or expenses
incurred as a result of issues relating to one class; and (h) shareholder
meeting costs that relate to a specific class.
    
 
DISTRIBUTION PLAN
 
   
Pursuant to Rule 12b-1 under the 1940 Act, the Group has adopted a Distribution
and Shareholder Service Plan with respect to its Investor Shares (the "Plan"),
under which the Fund is authorized to pay The Ohio Company, as the Fund's
principal underwriter, a periodic amount calculated at an annual rate not to
exceed twenty-five one-hundredths of one percent (.25%) of the average daily net
asset value of the Investor Shares of the Fund. Such amount may be used by The
Ohio Company to pay broker-dealers (including The Ohio Company), banks and other
institutions (a "Participating Organization") for distribution and/or
shareholder service assistance pursuant to an agreement between The Ohio Company
and the Participating Organization or for distribution assistance and/or
shareholder service provided by The Ohio Company pursuant to an agreement
between The Ohio Company and the Group. Under the Plan, a Participating
Organization may include The Ohio Company, its subsidiaries, and its affiliates.
The Ohio Company may from time to time waive all or a portion of the fees
payable to it pursuant to the Plan. Any such waiver will cause the total return
and yield of the Investor Shares of the Fund to be higher than it would
otherwise be absent such a waiver.
    
 
   
As authorized by the Plan, The Ohio Company has entered into a Rule 12b-1
Agreement with the Group pursuant to which The Ohio Company has agreed to
provide certain shareholder services in connection with Investor Shares of the
Fund purchased and held by The Ohio Company for the accounts of its customers
and Investor Shares of the Fund purchased and held by customers of The Ohio
Company directly, including, but not limited to, answering shareholder questions
concerning the Fund, providing information to shareholders on their investments
in the Investor Shares of the Fund and providing such personnel and
communication equipment as is necessary and appropriate to accomplish such
matters. In consideration of such services the Group has agreed to pay The Ohio
Company a monthly fee, computed at the annual rate of .25% of the average
aggregate net asset value of Investor Shares held during the period in customer
accounts for which The Ohio Company has provided services under this Agreement.
Such fees paid by the Group will be borne solely by the Investor Shares of the
Fund. Such fee may exceed the actual costs incurred by The Ohio Company in
providing such services.
    
 
In addition, The Ohio Company may enter into, from time to time, other Rule
12b-1 Agreements with selected dealers pursuant to which such dealers will
provide certain shareholder services such as those described above.
 
CUSTODIAN
 
The Group has appointed The Fifth Third Bank ("Fifth Third"), 38 Fountain Square
Plaza, Cincinnati, Ohio 45263, as the Fund's custodian. In such capacity, Fifth
Third will hold or arrange for the holding of all portfolio securities and other
assets acquired and owned by the Fund.
 
- --------------------------------------------------------------------------------
WHAT ARE MY RIGHTS AS A SHAREHOLDER?
- --------------------------------------------------------------------------------
 
   
The Group was organized as an Ohio business trust on March 23, 1993. The Group
currently consists of six funds. The shares of each of the funds of the Group,
other than the two money market funds, Cardinal Government Securities Money
Market Fund ("CGSMMF") and Cardinal Tax Exempt Money Market Fund ("CTEMMF"), are
currently offered in two separate classes: Investor A Shares, otherwise referred
to as Investor Shares, and Investor Y Shares, otherwise referred to as
Institutional Shares. CGSMMF and
    
 
20
<PAGE>   127
 
   
CTEMMF each have only one class of shares. Each share represents an equal
proportional 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.
    
 
   
Shareholders are entitled to one vote for each dollar of value invested and a
proportionate fractional vote for any fraction of a dollar invested, and will
vote in the aggregate and not by series except as otherwise expressly required
by law. For example, shareholders of the 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 accountants. However, shareholders
of the Fund will vote as a fund, and not in the aggregate with other
shareholders of the Group, for purposes of approval of amendments to the
investment advisory agreement as it relates to the Fund or any of the Fund's
fundamental policies.
    
 
   
Overall responsibility for the management of the Fund is vested in the Board of
Trustees of the Group. See "WHO MANAGES MY INVESTMENT OF THE FUND?" Individual
Trustees are elected by the shareholders of the Group, although Trustees may
under certain circumstances fill vacancies, including vacancies created by
expanding the size of the Board. Trustees 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 Ohio law. See "ADDITIONAL INFORMATION -
Miscellaneous" in the Statement of Additional Information for further
information.
    
 
An annual or special meeting of shareholders to conduct necessary business is
not required by the Declaration of Trust, the 1940 Act or other authority
except, under certain circumstances, to elect Trustees, amend the Declaration of
Trust, approve the investment advisory agreement and to satisfy certain other
requirements. To the extent that such a meeting is not required, the Group does
not intend to have an annual or special meeting.
 
The Group has represented to the Commission 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 and that the Group will
assist in communications with other shareholders as required by Section 16(c) of
the 1940 Act. At such 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 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 the 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 the 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 the Fund.
 
Shareholders should direct all inquiries concerning such matters to the Transfer
Agent in writing to 215 East Capital Street, Columbus, Ohio 43215, or by calling
(800) 282-9446.
 
Shareholders will receive unaudited semi-annual reports describing the
investment operations of the Fund and annual financial reports audited by
independent auditors.

                      CARDINAL GOVERNMENT OBLIGATIONS FUND

                              INSTITUTIONAL SHARES

         Cardinal Government Obligations Fund (the "Fund") is a diversified
investment fund of The Cardinal Group (the "Group"), an open-end, management
investment company. The Trustees of the Group have divided the Fund's beneficial
ownership into an unlimited number of transferable units called shares (the
"Shares"). The Fund offers multiple classes of Shares.

         The Fund's investment objectives are to maximize safety of capital and,
consistent with such objective, earn the highest available current income
obtainable from government securities. The current income earned from such
government securities may not be as great as the current income earned on lower
quality securities which have less liquidity and greater risk of nonpayment.
There can be no assurance that the Fund's investment objectives will be
achieved.

         THE SHARES OF THE FUND ARE NOT DEPOSITS OR OBLIGATIONS OF, OR
GUARANTEED OR ENDORSED BY ANY BANK, NOR ARE SUCH SHARES FEDERALLY INSURED BY THE
U.S. GOVERNMENT, THE FEDERAL DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE
BOARD OR ANY OTHER GOVERNMENTAL AGENCY. AN INVESTMENT IN THE FUND INVOLVES
CERTAIN INVESTMENT RISKS, INCLUDING THE POSSIBLE LOSS OF PRINCIPAL.

to an administrative services fee but are subject to a Rule 12b-1 fee and are
generally sold with a front-end sales charge.

         The purpose of the above table is to assist a potential purchaser of
the Fund's Institutional Shares in understanding the various costs and expenses
that an investor in the Fund will bear directly or indirectly. See "WHO MANAGES
MY INVESTMENT IN THE FUND?" for a more complete discussion of the shareholder
transaction expenses and annual operating expenses of the Fund. The example and
expenses above reflect current fees. THE FOREGOING EXAMPLE SHOULD NOT BE

                             PERFORMANCE INFORMATION

         From time to time the Fund may advertise its average annual total
return, cumulative return and/or yield. SUCH RETURN AND YIELD FIGURES ARE BASED
UPON HISTORICAL EARNINGS AND ARE NOT INTENDED TO INDICATE FUTURE PERFORMANCE.
The average annual total return advertised by the Fund refers to the return
generated by an investment in the Fund over certain specified periods since the
establishment of the Fund (including the term of CGOF's operations). The average
annual total return over a period equates the amount of an initial investment in
the Fund to the amount redeemable at the end of that period assuming that any
dividends and distributions earned by an investment in the Fund are immediately
reinvested and the maximum applicable sales charge, if any, is deducted from the
initial investment at the time of investment. Such figure is then annualized.
The cumulative return advertised refers to the total return on a hypothetical
investment over the relevant period and equates the amount of an initial
investment in the Fund to the amount redeemable at the end of that period
assuming that any dividends and distributions are immediately reinvested and the
maximum sales charge, if any, is deducted from the initial investment. Yield
will be computed by dividing the Fund's net investment 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.

         In addition, from time to time the Fund may include in its sales
literature and shareholder reports a quote of the current "distribution" rate
for the Fund. A distribution rate is simply a measure of the level of dividends
distributed for a specified period and is computed by dividing the total amount
of dividends per share paid by the Fund during the past 12 months by a current
maximum offering price. It differs from yield, which is a measure of the income
actually earned by the Fund's investments, and from total return, which is a
measure of the income actually earned by, plus the effect of any realized and
unrealized appreciation or depreciation of, such investments during a stated
period. A distribution rate is, therefore, not intended to be a complete measure
of performance. A distribution rate may sometimes be greater than yield since,
for instance, it may include short-term and possibly long-term gains (which may
be non-recurring), may not include the effect of amortization of bond premiums
and does not reflect unrealized gains or losses.

         Investors may also judge the performance of any class of Shares of the
Fund by comparing or referencing its performance to the performance of other
mutual funds or mutual fund portfolios with comparable investment objectives and
policies through various


                                      - 8 -

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., Morningstar, Inc. and CDA Investment Technologies, Inc.
Comparisons may also be made to indices or data published in Money Magazine,
Forbes, Barron's, The Wall Street Journal, The New York Times, The Columbus
Dispatch, Business Week, U.S.A. Today and Consumer Reports. In addition to
performance information, general information about the Fund that appears in a
publication such as those mentioned above may be included in advertisements and
in reports to shareholders.

         Further information about the performance of the Fund is contained in
an Annual Report to Shareholders which may be obtained without charge by
contacting the Group at the telephone number set forth on the cover page of this
Prospectus. Performance quotations will be computed separately for Investor and
Institutional Shares. Because of differences in the fees and/or expenses borne
by Investor and Institutional Shares, the net yield and total return on each
such class can be expected, at any given time, to differ from the net yield and
total return of such other class.

                                WHAT IS THE FUND?

         The Fund is one separate diversified investment fund of the Group,
which was organized on March 23, 1993, as an Ohio business trust. The Group is
registered and operates as an open-end management investment company as defined
in the Investment Company Act of 1940, as amended (the "1940 Act"). The Fund was
organized for the purpose of acquiring all of the assets and liabilities of CGOF
to effect a reorganization of CGOF from a stand-alone investment company to a
separate series of the Group (the "Reorganization"). The Reorganization was
effected as of May 1, 1996.

         The Fund is designed for individuals, corporations, fiduciaries, and
institutions who wish to invest for current income in a diversified,
professionally managed portfolio of securities issued by the U.S. Government and
securities directly guaranteed by the full faith and credit of the U.S.
Government -- without having to become involved in the detailed accounting and
safekeeping procedures normally associated with direct investment in these
securities.

                       WHAT ARE THE INVESTMENT OBJECTIVES
                            AND POLICIES OF THE FUND?

IN GENERAL

         The Fund's investment objectives are to maximize safety of capital and,
consistent with such objective, earn the highest available current income
obtainable from government securities. The current income earned from such
government securities may not be as great as the current income earned on lower
quality securities which have less liquidity and greater risk of nonpayment.

         The Fund's investment objectives are a fundamental policy of the Fund,
which means that they may be changed only with the approval of a majority of the
outstanding Shares of the Fund (as defined below under "WHAT ARE MY RIGHTS AS A
SHAREHOLDER?). There can be no assurance that the investment objectives of the
Fund will be achieved.

         Under normal market conditions, the Fund will invest substantially all,
but in no event less than 65% of the value of its total assets, in obligations
issued or guaranteed by the U.S. Government or its agencies or instrumentalities
("U.S. Government Securities"). The Fund may also invest, under normal market
conditions, in the fixed income instruments described below and in repurchase
agreements. It may also engage in the options transactions described below.

         The Fund may, for daily cash management purposes, invest in high
quality money market securities and in repurchase agreements. In addition, the
Fund may invest, without limit, in any combination of U.S. Government
Securities, money market securities and repurchase agreements when, in the
opinion of the Adviser, it is determined that a temporary defensive position is
warranted based upon current market conditions. The Fund may also invest in
securities of other investment companies, as described more fully below.

         The types of U.S. Government Securities invested in by the Fund will
include obligations issued by 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 ("Ginnie Mae") 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


                                     - 10 -
<PAGE>   142
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. The Fund will invest in the obligations of such
agencies or instrumentalities only when the Adviser believes that the credit
risk with respect thereto is minimal.

          Certain securities held by the Fund may have mortgage obligations
backing such securities, including among others, conventional thirty year fixed
rate mortgage obligations, graduated payment mortgage obligations, fifteen year
mortgage obligations and adjustable rate mortgage obligations. All of these
mortgage obligations can be used to create pass-through securities. A
pass-through security is created when mortgage obligations are pooled together
and undivided interests in the pool or pools are sold. The cash flow from the
mortgage obligations is passed through to the holders of the securities in the
form of periodic payments of interest, principal and prepayments (net of a
service fee). Prepayments occur when the holder of an individual mortgage
obligation prepays the remaining principal before the mortgage obligation's
scheduled maturity date. As a result of the pass-through of prepayments of
principal on the underlying securities, mortgage-backed securities are often
subject to more rapid prepayment of principal than their stated maturity would
indicate. Because the prepayment characteristics of the underlying mortgage
obligations vary, it is not possible to predict accurately the realized yield or
average life of a particular issue of pass-through certificates. Prepayment
rates are important because of their effect on the yield and price of the
securities. Accelerated prepayments have an adverse impact on yields for
pass-through certificates purchased at a premium (i.e., a price in excess of
principal amount) and may involve additional risk of loss of principal because
the premium may not have been fully amortized at the time the obligation is
repaid. The opposite is true for pass-through certificates purchased at a
discount. The Fund may purchase mortgage-related securities at a premium or at a
discount. Reinvestment of principal payments may occur at higher or lower rates
than the original yield on such securities. Due to the prepayment feature and
the need to reinvest payments and prepayments of principal at current rates,
mortgage-related securities can be less effective than typical bonds of similar
maturities at maintaining yields during periods of declining interest rates.


                                     - 11 -
<PAGE>   143
         Certain debt securities such as, but not limited to, mortgage backed
securities, as well as other securities subject to prepayment of principal prior
to the stated maturity date, are expected to be repaid prior to their stated
maturity dates. As a result, the effective maturity of these securities is
expected to be shorter than the stated maturity. For purposes of calculating the
Fund's weighted average portfolio maturity, the effective maturity of such
securities will be used.

         Under present market conditions, the Fund expects to invest a
substantial amount of its portfolio in Ginnie Mae certificates, which are
mortgage-backed securities representing part ownership in a specific pool of
mortgage loans insured by the Federal Housing Administration or Farmers Home
Administration or guaranteed by the Veterans Administration. Should market or
economic conditions warrant, this practice may be changed at the discretion of
the Adviser. Ginnie Mae guarantees the timely payment of monthly installments of
principal and interest on its certificates, when due, whether or not payments
are received on the underlying mortgage loans, and the full faith and credit of
the United States is pledged to the timely payment by Ginnie Mae of such
principal and interest.

         Although the mortgage loans in the pool underlying a Ginnie Mae
certificate will have maturities of up to thirty years, the actual average life
of the Ginnie Mae certificates typically will be substantially less because the
mortgage loans will be subject to normal principal amortization and may be
prepaid prior to maturity. Prepayment rates vary widely and may be affected by
changes in market interest rates and general economic conditions. In periods of
falling interest rates, the rate of prepayment tends to increase, thereby
shortening the actual average life of the Ginnie Mae certificates 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 actual average life of the Ginnie Mae certificates and
extending the period of time over which income at the lower rates is received.
Accordingly, it is not possible to accurately predict the average life of a
particular pool. Standard practice is to treat Ginnie Mae certificates as having
effective maturities of twelve years. Reinvestment of principal payments may
occur at higher or lower rates than the original yield on the certificates. Due
to the prepayment feature and the need to reinvest payments and prepayments of
principal at current rates, Ginnie Mae certificates can be less effective than
typical bonds of similar maturities at maintaining yields during periods of
declining interest rates.

RISK FACTORS AND INVESTMENT TECHNIQUES

         GENERAL. Like any investment program, an investment in the Fund entails
certain risks. The value of the Fund's portfolio securities, and therefore the
Fund's net asset value per share, may increase or decrease due to various
factors, principally changes in prevailing interest rates. Generally, a rise in
interest rates will result in a decrease in the Fund's net asset value per
share, while a drop in interest rates will result in an increase in the Fund's
net asset value per share.

         The Fund may invest in put and call options and futures, as described
below. Such instruments are considered to be "derivatives." A derivative is
generally defined as an instrument whose value is based upon, or derived from,
some underlying index, reference rate (e.g., interest rates), security,
commodity or other asset. The Fund will not invest more than 10% of its total
assets in such derivatives at any one time.

         REPURCHASE AGREEMENTS. Securities held by the Fund may be subject to
repurchase agreements. Under the terms of the repurchase agreement, the Fund
would acquire securities from a financial institution such as a well-established
securities dealer or a bank which is a member of the Federal Reserve System
which the Adviser deems creditworthy under guidelines approved by the Group's
Board of Trustees. At the time of purchase, the bank or securities dealer agrees
to repurchase the underlying securities from the Fund at a specified time and
price. The resale price reflects the purchase price plus an agreed upon market
rate of interest which is unrelated to the coupon rate or maturity of the
underlying security. The Fund will only enter into a repurchase agreement where
(i) the underlying securities are of the type which the Fund's investment
policies would allow it to purchase directly, (ii) the market value of the
underlying security, including interest accrued, will be at all times equal to
or exceed the value of the repurchase agreement, and (iii) payment for the
underlying securities is made only upon physical delivery or evidence of
book-entry transfer to the account of the Fund's custodian or a bank acting as
agent. The Adviser will be responsible for continuously monitoring such
requirements.

         WHEN-ISSUED AND DELAYED-DELIVERY TRANSACTIONS. The Fund may also
purchase securities on a when-issued or delayed-delivery basis. The 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, although such transactions represent a
form of leveraging. 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


                                     - 13 -
<PAGE>   145
delivery takes place. The Fund will not pay for such securities or start earning
interest on them until they are received. When the Fund agrees to purchase such
securities, its 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, the Fund relies on the seller to complete the
transaction; the seller's failure to do so may cause the Fund to miss a price or
yield considered to be advantageous.

         The Fund's commitments to purchase when-issued securities will not
exceed 25% of the value of its total assets absent unusual market conditions. In
the event that its commitments to purchase when-issued securities ever exceed
25% of the value of its assets, the Fund's liquidity and the ability of the
Adviser to manage it might be adversely affected.

         PUT AND CALL OPTIONS. Subject to its investment policies and for
purposes of hedging against market risks related to its portfolio securities,
the Fund may purchase put and call options on securities. Purchasing options is
a specialized investment technique that entails a substantial risk of a complete
loss of the amounts paid as premiums to writers of options. The Fund will
purchase put options only on securities in which the Fund may otherwise invest.
The Fund may also engage in writing call options from time to time as the
Adviser deems appropriate. The Fund will write only covered call options
(options on securities owned by the Fund). In order to close out a call option
it has written, the Fund will 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 has written. When a
portfolio security subject to a call option is sold, the Fund will effect a
closing purchase transaction to close out any existing call option on that
security. If the 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 market
conditions, it is not expected that the underlying value of portfolio securities
subject to such options would exceed 25% of the net assets of the Fund.

         The Fund, as part of its option transactions, also may purchase index
put and call options and write index options. As with options on individual
securities, the Fund will write only covered index call options. Through the
writing or purchase of index options the Fund can achieve many of the same
objectives as through the use of options on individual securities. Options on
securities indices are similar to options on a security except


                                     - 14 -
<PAGE>   146
that, rather than the right to take or make delivery of a security at a
specified price, an option on a securities index gives the holder the right to
receive, upon exercise of the option, an amount of cash if the closing level of
the securities index upon which the option is based is greater than, in the case
of a call, or less than, in the case of a put, the exercise price of the option.

         Price movements in securities which the Fund owns or intends to
purchase probably will not correlate perfectly with movements in the level of an
index and, therefore, the Fund bears the risk of a loss on an index option that
is not completely offset by movements in the price of such securities. Because
index options are settled in cash, a call writer cannot determine the amount of
its settlement obligations in advance and, unlike call writing on specific
securities, cannot provide in advance for, or cover, its potential settlement
obligations by acquiring and holding the underlying securities. The Fund may be
required to segregate assets or provide an initial margin to cover index options
that would require it to pay cash upon exercise.

         FUTURES CONTRACTS. The Fund may also enter into contracts for the
future delivery of securities and futures contracts based on a specific
security, class of securities or an index, purchase or sell options on any such
futures contracts and engage in related closing transactions. A futures contract
on a securities index is an agreement obligating either party to pay, and
entitling the other party to receive, while the contract is outstanding, cash
payments based on the level of a specified securities index.

         The Fund may engage in such futures contracts in an effort to hedge
against market risks. For example, when interest rates are expected to rise or
market values of portfolio securities are expected to fall, the Fund can seek
through the sale of futures contracts to offset a decline in the value of its
portfolio securities. When interest rates are expected to fall or market values
are expected to rise, the Fund, through the purchase of such contracts, can
attempt to secure better rates or prices for the Fund than might later be
available in the market when it effects anticipated purchases.

         The acquisition of put and call options on futures contracts will,
respectively, give the Fund the right (but not the obligation), for a specified
price, to sell or to purchase the underlying futures contract, upon exercise of
the option, at any time during the option period.

         Aggregate initial margin deposits for futures contracts, and premiums
paid for related options, may not exceed five percent of the Fund's total
assets, and the value of securities that are the subject of such futures and
options (both for receipt and delivery)


                                     - 15 -
<PAGE>   147
may not exceed one-third of the market value of the Fund's total assets. Futures
transactions will be limited to the extent necessary to maintain the Fund's
qualification as a regulated investment company.

         Futures transactions involve brokerage costs and require the Fund to
segregate assets to cover contracts that would require it to purchase
securities. The Fund may lose the expected benefit of futures transactions if
interest rates or securities prices move in an unanticipated manner. Such
unanticipated changes may also result in poorer overall performance than if the
Fund had not entered into any futures transactions. In addition, the value of
the Fund's futures positions may not prove to be perfectly or even highly
correlated with the value of its portfolio securities, limiting the Fund's
ability to hedge effectively against interest rate and/or market risk and giving
rise to additional risks. There is no assurance of liquidity in the secondary
market for purposes of closing out futures positions.

         INVESTMENT COMPANY SECURITIES. The Fund may also invest up to 10% of
the value of its total assets in the securities of other investment companies
subject to the limitations set forth in the 1940 Act. The Fund intends to invest
in the securities of other investment companies which, in the opinion of the
Adviser, will assist the Fund in achieving its objectives and in money market
mutual funds for purposes of short-term cash management. The Fund's investment
in such other investment companies may result in the duplication of fees and
expenses, particularly investment advisory fees. For a further discussion of the
limitations on the Fund's investments in other investment companies, see
"INVESTMENT OBJECTIVES AND POLICIES -- Additional Information on Portfolio
Instruments -- Securities of Other Investment Companies" in the Fund's Statement
of Additional Information.

INVESTMENT RESTRICTIONS

         The 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 the Fund (as
defined below under "WHAT ARE MY RIGHTS AS A SHAREHOLDER?").

         The 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, more than 5%
         of the value of the Fund's total assets would be invested in such
         issuer, or the Fund would hold more than 10% of the outstanding voting
         securities of the issuer, except that up to 25% of the value of the
         Fund's total assets


                                     - 16 -
<PAGE>   148
         may be invested without regard to such limitations. There is no limit
         to the percentage of assets that may be invested in U.S. Treasury
         bills, notes, or other obligations issued or guaranteed by the U.S.
         Government or its agencies or instrumentalities.

                  2. 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) 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.

                  3. Borrow money or issue senior securities, except that the
         Fund may borrow from banks or enter into reverse repurchase agreements
         or dollar roll agreements for temporary purposes in amounts up to 10%
         of the value of its total assets at the time of such borrowing and
         except as permitted pursuant to an exemption from the 1940 Act. The
         Fund will not purchase securities while its borrowings (including
         reverse repurchase agreements and dollar roll agreements) exceed 5% of
         its total assets.

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

         The following additional investment restriction may be changed without
the vote of a majority of the outstanding Shares of the Fund. The Fund will not:

                  1. Purchase or otherwise acquire any securities, if as a
         result, more than 15% of the Fund's net assets would be invested in
         securities that are illiquid.

               HOW DO I PURCHASE INSTITUTIONAL SHARES OF THE FUND?

GENERAL

         The Fund's Institutional Shares are continuously offered and may be
purchased through procedures established by The Ohio Company, principal
underwriter of the Fund's Shares, in connection with accounts for which banks,
broker-dealers, savings and loan associations, trust companies (including The
Ohio Company), qualified investment advisers and certain other financial
institutions serve in a fiduciary capacity on behalf of customers or
beneficiaries (collectively, "Financial Institutions"). Normally, Financial
Institutions will hold Institutional Shares of record for their customers or
beneficiaries. With respect to Institutional Shares so sold, it is the
responsibility of the holder of record to transmit purchase or redemption orders
to The Ohio Company and to deliver funds for the purchase thereof on a timely
basis. Beneficial ownership of Institutional Shares of the Fund may be recorded
by the Institutions and reflected in the account statements provided to their
customers or beneficiaries.

         The Group reserves the right to reject any order for the purchase of
Institutional Shares in whole or in part. The applicable Financial Institution
will receive a confirmation of each new transaction in its account. Certificates
representing Shares will not be issued.

         Institutional Shares are purchased at the net asset value per share
(see "HOW IS NET ASSET VALUE CALCULATED?") next determined after receipt by The
Ohio Company or its agents of an order and payment. There is no sales charge
imposed in connection with the purchase of Institutional Shares of the Fund.
Depending upon the terms of a particular account, a Financial Institution may
charge customer account fees for services provided in connection with an
investment in the Fund. Information concerning these services and any charges
may be obtained from such Financial Institution. This Prospectus should be read
in conjunction with any such information so received.

         From time to time, The Ohio Company, from its own resources, may
provide compensation to securities dealers in connection with sales of shares of
the Cardinal Funds. Such compensation will include financial assistance to
securities dealers in connection with conferences, sales or training programs
for their employees, seminars for the public, advertising, sales campaigns
and/or shareholder services and programs regarding one or more of the Cardinal
Funds and other dealer-sponsored programs or events. In some instances, this
compensation may be made available only to certain securities dealers whose
representatives have sold or are expected to sell significant amounts of shares
of the Cardinal


                                     - 18 -
<PAGE>   150
Funds. Compensation will 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. Securities dealers may not
use sales of the Fund's Shares to qualify for this compensation to the extent
such may be prohibited by the laws of any state or any self-regulatory agency,
such as the National Association of Securities Dealers, Inc. In addition, The
Ohio Company may make ongoing payments to brokerage firms, financial
institutions (including banks) and others to facilitate the administration and
servicing of shareholder accounts. None of the aforementioned additional
compensation is paid for by the Fund or its shareholders.

                       WHAT DISTRIBUTIONS WILL I RECEIVE?

         A dividend consisting of net income is declared daily to Shareholders
of the Fund at the close of business on the day of declaration, and such
dividends are generally paid monthly. Dividends consisting of long-term capital
gains normally will be distributed only once annually. Dividends and
distributions will be paid only in additional Institutional Shares and not in
cash; except, however, that for dividends and distributions of $10 or more, a
shareholder may specifically request that such amounts be paid to him in cash.
Dividends are paid in cash not later than seven days after a shareholder's
complete redemption of his Institutional Shares in the Fund.

         The Fund's net investment income available for distribution to the
holders of Institutional Shares will be reduced by the amount of administrative
services fees paid under the Services Plan described below.

                    HOW MAY I REDEEM MY INSTITUTIONAL SHARES?

         Investors may redeem Institutional Shares of the Fund on any Business
Day at the net asset value per Institutional Share next determined following the
receipt by the Transfer Agent, 215 East Capital Street, Columbus, Ohio 43215, of
written or telephonic notice to redeem, as described more fully below. See "HOW
IS NET ASSET VALUE CALCULATED?", below, for a description of when net asset
value is determined.

         As requested, The Ohio Company, on behalf of a shareholder, will
forward the foregoing notice to redeem to the Transfer Agent without charge.
Other broker-dealers may assist a shareholder in redeeming his Institutional
Shares and may charge a fee for such services.


                                     - 19 -
<PAGE>   151
         The Group will make payment for redeemed Institutional Shares as
promptly as practicable but in no event more than seven days after receipt by
the Transfer Agent of the foregoing notice. The Group reserves the right to
delay payment for the redemption of Institutional Shares where such
Institutional Shares were purchased with other than immediately available funds,
but only until the purchase payment has cleared (which may take fifteen or more
days from the date the purchase payment is received by the Fund). The purchase
of Fund Institutional Shares by wire transfer of federal funds would avoid any
such delay.

         The Group intends to pay cash for all Institutional Shares redeemed,
but, under abnormal conditions which make payment in cash unwise, the Group may
make payment wholly or partly in readily marketable portfolio securities at
their then market value equal to the redemption price. In such cases, an
investor may incur brokerage costs in converting such securities to cash.

         The Group may suspend the right of redemption or may delay payment
during any period the determination of net asset value is suspended. See "HOW IS
NET ASSET VALUE CALCULATED?".

         Due to the high cost of maintaining accounts, the Group reserves the
right to redeem, at net asset value, involuntarily Shares in any account at the
then current net asset value if at any time redemptions (but not as a result of
a decrease in the market price of such Shares or the deduction of any sales
charge) have reduced a shareholder's total investment in the Fund to a net asset
value below $500. A shareholder will be notified in writing that the value of
Fund Shares in the account is less than $500 and allowed not less than 30 days
to increase his investment in the Fund to $500 before the redemption is
processed. Proceeds of redemptions so processed, including dividends declared to
the date of redemption, will be promptly paid to the shareholder.

REDEMPTION BY MAIL

         Shareholders may redeem Institutional Shares of the Fund by submitting
a written request therefor to the Transfer Agent, at 215 East Capital Street,
Columbus, Ohio 43215. The Transfer Agent will request a signature guarantee by
an eligible guarantor institution as described below. However, a signature
guarantee will not be required if (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, provided, however, that the address of
record has not been changed within the preceding 15 days. For purposes of this
policy, an "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 the


                                     - 20 -
<PAGE>   152
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 or (2) it has reason to believe that the transaction would otherwise
be improper.

REDEMPTION BY TELEPHONE

         Shareholders may redeem Institutional Shares of the Fund by calling the
Group at the telephone number set forth on the front of this Prospectus. The
shareholder may direct that the redemption proceeds be mailed to the address of
record.

         Neither the Group, the Fund nor its service providers will be liable
for any loss, damages, expense or cost arising out of any telephone redemption
effected in accordance with the Group's telephone redemption procedures, acting
upon instructions reasonably believed to be genuine. The Group will employ
procedures designed to provide reasonable assurances that instructions by
telephone are genuine; if these procedures are not followed, the Group, the Fund
or its service providers may be liable for any losses due to unauthorized or
fraudulent instructions. These procedures may include recording all phone
conversations, sending confirmations to shareholders within 72 hours of the
telephone transaction, and verification of account name and account number or
tax identification number. If, due to temporary adverse conditions, investors
are unable to effect telephone transactions, shareholders may also redeem their
Institutional Shares by mail as described above.


                  WHAT OTHER SHAREHOLDER PROGRAMS ARE PROVIDED?

ACH PROCESSING

         The Fund offers ACH privileges. Investors may use ACH processing to
make subsequent purchases, redeem Shares and/or electronically transfer
distributions paid on Shares, in addition to the other methods described in this
Prospectus. ACH provides a method by which funds may be automatically
transferred to or from an authorized bank account at a Federal Reserve member
bank that is an ACH member. Please contact your representative if you are
interested in ACH processing.

EXCHANGE PRIVILEGE

         Holders of Institutional Shares of the Fund may, provided the amount to
be exchanged meets the applicable minimum investment requirements and the
exchange is made in states where it is legally authorized, exchange, at
respective net asset values, Institutional Shares of the Fund for:


                                     - 21 -
<PAGE>   153
         Institutional Shares of Cardinal Aggressive Growth Fund,
         an equity fund seeking appreciation of capital;

         Institutional Shares of Cardinal Balanced Fund,
         a fund seeking current income and long-term growth of both capital and
         income;

         Institutional Shares of The Cardinal Fund, an equity fund seeking
         long-term growth of capital and income;

         Shares of Cardinal Government Securities Money Market Fund,
         a U.S. Government securities money market fund; or

         Shares of Cardinal Tax Exempt Money Market Fund,
         a tax-free money market fund.

         The foregoing exchange privilege must be made by written or telephonic
authorization. A shareholder should notify The Ohio Company of his desire to
make an exchange, and The Ohio Company will furnish, as necessary, a prospectus
and an application form to open the account. The Transfer Agent will require
that any written authorization of an exchange include a signature guarantee as
described above under "HOW MAY I REDEEM MY SHARES? -- Redemption by mail."
However, a signature guarantee will not be required if the exchange requested is
within the same account or into an existing account of the shareholder held in
the same name or names and in the same capacity as the account from which the
exchange is to be made. Shareholders may also authorize an exchange of Shares of
the Fund by telephone. Neither the Group, the Fund nor any of its service
providers will be liable for any loss, damages, expense or cost arising out of
any telephone exchange authorization to the extent and subject to the
requirements set forth under "HOW MAY I REDEEM MY SHARES? -- Redemption by
telephone" above.

         In the event the status of a shareholder or the capacity in which a
shareholder holds Institutional Shares changes such that he is no longer
eligible to purchase or hold Institutional Shares of the Fund, then such
Institutional Shares will be automatically exchanged for Investor Shares of the
Fund at respective net asset value per share.

         For tax purposes, an exchange is treated as a redemption and a new
purchase.

         The Group may, at any time, modify or terminate the foregoing exchange
privilege. The Group, however, will give shareholders of the Fund 60 days'
advance written notice of any such modification or termination.

<PAGE>   154
                       HOW IS NET ASSET VALUE CALCULATED?

         The net asset value of the Fund is determined once daily as of 4:00
P.M. Eastern Time, on each Business Day. A "Business Day" is a day on which the
New York Stock Exchange is open for business and any other day (other than a day
on which no Shares of the Fund are tendered for redemption and no order to
purchase any Shares of the Fund is received) during which there is a sufficient
degree of trading in the Fund's portfolio securities that the net asset value
might be materially affected by changes in the value of the portfolio
securities. The net asset value per share of each class of Shares of the Fund is
computed by dividing the sum of the value of the Fund's portfolio securities
plus any cash and other assets (including interest and dividends accrued but not
received) allocable to such class minus all liabilities (including estimated
accrued expenses) allocable to such class by the total number of Shares of that
Class then outstanding.

         The net asset value per share will fluctuate as the value of the
investment portfolio of the Fund changes.

         Portfolio securities for which over-the-counter market quotations are
readily available are valued at the bid price. The Fund uses one or more pricing
services to provide such market quotations. Securities and other assets for
which market quotations are not readily available are valued at fair value as
determined in good faith by or under the direction of the Board of Trustees of
the Group.

         Determination of the net asset value may be suspended at times when (a)
trading on the New York Stock Exchange is restricted by applicable rules and
regulations of the Commission, (b) the New York Stock Exchange is closed for
other than customary weekend and holiday closings, (c) an emergency exists as a
result of which disposal by the Group of portfolio securities owned by the Fund
or valuation of net assets of the Fund is not reasonably practicable, or (d) the
Commission has by order permitted such suspension.

                      DOES THE FUND PAY FEDERAL INCOME TAX?

         Each of the funds of the Group, including the Fund, is treated as a
separate entity for federal income tax purposes and intends to qualify as a
"regulated investment company" under the Code for so long as such qualification
is in the best interest of that fund's shareholders. Qualification as a
regulated investment company under the Code requires, among other things, that
the regulated investment company distribute to its shareholders at least 90% of
its investment company taxable income. The Fund contemplates declaring as
dividends 100% of the Fund's investment company taxable income (before deduction
of dividends paid).


                                     - 23 -
<PAGE>   155
         A non-deductible 4% excise tax is imposed on regulated investment
companies that do not distribute in each calendar year (regardless of whether
they otherwise have a non-calendar taxable year) an amount equal to 98% of their
ordinary income for the calendar year plus 98% of their capital gain net income
for the one-year period ending on October 31 of such calendar year. The balance
of such income must be distributed during the next calendar year. If
distributions during a calendar year were less than the required amount, the
Fund would be subject to a nondeductible excise tax equal to 4% of the
deficiency.

                              WHAT ABOUT MY TAXES?

         It is expected that the Fund will distribute annually to shareholders
all or substantially all of the Fund's net ordinary income and net realized
capital gains and that such distributed net ordinary income and distributed net
realized capital gains will be taxable income to shareholders for federal income
tax purposes, even if paid in additional Shares of the Fund and not in cash.
Since all of the Fund's net investment income is expected to be derived from
earned interest and short-term capital gains, it is anticipated that no part of
any distribution will be eligible for the dividends received deduction for
corporations.

         Distribution by the Fund of the excess of net long-term capital gain
over net short-term capital loss is taxable to shareholders as long-term capital
gain in the year in which it is received, regardless of how long the shareholder
has held the Shares. Such distributions are not eligible for the dividends
received deduction.

         If the net asset value of a Share is reduced below the shareholder's
cost of that Share by the distribution of income or gain realized on the sale of
securities, the distribution is a return of invested principal, although taxable
as described above.

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

         The foregoing is intended only as a brief summary of some of the
important tax considerations generally affecting the Fund and its shareholders.
Potential investors in the Fund are urged to consult their tax advisers
concerning the application of federal,


                                     - 24 -
<PAGE>   156
state and local taxes as such laws and regulations affect their own
tax situation.

         The Transfer Agent will inform shareholders at least annually of the
amount and nature of such income and capital gains.

                     WHO MANAGES MY INVESTMENT IN THE FUND?

   
         Except where shareholder action is required by law, all of the
authority of the Group is exercised under the direction of the Group's
Trustees. Unless so required by the Group's Declaration of Trust or By-Laws or
by Ohio law, at any given time all of the Trustees may not have been elected by
the shareholders of the Group. The Trustees empowered to elect officers and 
contract with and provide for the compensation of agents, consultants and 
other professionals to assist and advise it in its day-to-day operations. The 
Group will be managed in accordance with its Declaration of Trust and the laws 
of Ohio governing business trusts. 
    

         The Trustees of the Group 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 the Adviser or The Ohio Company receives any
compensation from the Group for acting as a Trustee of the Group. The officers
of the Group receive no compensation directly from the Group for performing the
duties of their offices. The Adviser receives fees from the Group for acting as
investment adviser and manager and as dividend and transfer agent and for
providing certain fund accounting services. The Ohio Company receives no fees
under its Distribution Agreement with the Group with respect to Institutional
Shares of the Fund but may receive fees under the Administrative Services Plan
discussed below.

INVESTMENT ADVISER AND MANAGER

         Cardinal Management Corp. (the "Adviser"), 155 East Broad Street,
Columbus, Ohio 43215, a wholly owned subsidiary of The Ohio Company, is the
investment adviser and manager of the Fund. The Adviser is also the investment
adviser and manager of each of the other Cardinal Funds.

   
         The Ohio Company, an investment banking firm organized in 1925, is a
member of the New York and Chicago Stock Exchanges, other regional stock
exchanges and the National Association of Securities Dealers, Inc. Descendants
of H.P. and R.F. Wolfe, deceased, and members of their families, through their
possession of a majority of voting stock, may be considered controlling persons
of The Ohio Company. The Ohio Company serves as principal underwriter for each
of the Cardinal Funds.
    

         In its capacity as investment adviser, and subject to the ultimate
authority of the Group's Board of Trustees, the Adviser,


                                     - 25 -
<PAGE>   157
in accordance with the Fund's investment objectives and policies, manages the
Fund, and makes decisions with respect to and places orders for all purchases
and sales of its portfolio securities. Since the inception of CGOF (the Fund's
predecessor), John R. Carle has been primarily responsible for the day-to-day
management of CGOF's portfolio. It is expected that, upon consummation of the
Reorganization, Mr. Carle will be the portfolio manager for the Fund. Mr. Carle
has been a portfolio manager with the Adviser and/or The Ohio Company since
1971. In addition, pursuant to the Investment Advisory Agreement, the Adviser
generally assists in all aspects of the Fund's administration and operation.

         For the services provided and expenses assumed pursuant to its
investment advisory agreement with the Group with respect to the Fund, the
Adviser receives a fee from the Fund, computed daily and paid monthly at the
annual rate of .50% of average net daily assets of the Fund. The Adviser may,
however, periodically waive all or a portion of its advisory fee with respect to
the Fund to increase the net income of the Fund available for distribution as
dividends. The waiver of such fee will cause the yield of the Fund to be higher
than it would otherwise be in the absence of such a waiver.

DIVIDEND AND TRANSFER AGENT AND FUND ACCOUNTANT

         The Group has entered into a Transfer Agency and Fund Accounting
Agreement with Cardinal Management Corp. (the "Transfer Agent"), 215 East
Capital Street, Columbus, Ohio 43215, pursuant to which the Transfer Agent has
agreed to act as the Fund's transfer agent and dividend disbursing agent. In
consideration of such services, the Fund has agreed to pay the Transfer Agent an
annual fee, paid monthly, equal to $21 per shareholder account plus
out-of-pocket expenses. In addition, the Transfer Agent provides certain fund
accounting services for the Fund. The Transfer Agent receives a fee from the
Fund for such services equal to a fee computed daily and paid periodically at an
annual rate of .03% of the Fund's average daily net assets of up to $100 million
and .01% of the Fund's average daily net assets in excess of $100 million.

DISTRIBUTOR

         The Group has entered into a Distributor's Contract with The Ohio
Company, 155 East Broad Street, Columbus, Ohio 43215, pursuant to which Shares
of the Fund will be offered continuously on a best efforts basis by The Ohio
Company and dealers selected by The Ohio Company. H. Keith Allen is an officer
and trustee of the Group and an officer and director of The Ohio Company. Frank
W. Siegel is an officer and trustee of the Group and an officer of The Ohio
Company. James M. Schrack II is an officer of both the Group and The Ohio
Company. The Ohio Company receives no compensation under the Distributor's
Contract with respect to distribution of the Institutional Shares of the Fund.


                                     - 26 -
<PAGE>   158
EXPENSES

         The Adviser bears all expenses in connection with the performance of
its services as investment adviser, manager, transfer agent and fund accountant
other than the cost of securities (including brokerage commissions, if any)
purchased for the Fund. The Trustees reserve the right to allocate certain other
expenses, which can reasonably be identified as relating to a particular class,
solely to such class, including Institutional Shares as they deem appropriate
("Class Expense"). Such expense include (a) transfer agency fees identified as
being attributable to a specific class; (b) printing and postage expenses
related to preparing and distributing materials such as shareholder reports,
prospectuses and proxy statements to current shareholders of a specific class;
(c) Blue Sky registration fees incurred by a class of shares; (d) SEC
registration fees incurred by a class; (e) expenses of administrative personnel
and services as required to support the shareholders of a specific class; (f)
litigation or other legal expenses and audit or other accounting expenses
relating solely to one class; (g) trustees' fees or expenses incurred as a
result of issues relating to one class; and (h) shareholder meeting costs that
relate to a specific class.

ADMINISTRATIVE SERVICES PLAN

         The Group has adopted an Administrative Services Plan with respect to
the Fund's Institutional Shares (the "Services Plan") pursuant to which the Fund
is authorized to pay compensation to Financial Institutions, which may include
The Ohio Company, which agree to provide certain ministerial, record keeping
and/or administrative support services for their customers, account holders or
beneficiaries (collectively, "customers") who are the beneficial or record owner
of Institutional Shares of the Fund. In consideration for such services, a
Financial Institution receives a fee from the Fund, computed daily and paid
monthly, at an annual rate of up to .15% of the average daily net asset value of
Institutional Shares of the Fund owned beneficially or of record by such
Financial Institution's customers for whom the Financial Institution provides
such services.

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


                                     - 27 -
<PAGE>   159
Institutional 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 The Ohio Company pursuant to which The Ohio Company has
agreed to provide certain administrative support services in connection with
Institutional Shares of the Fund owned of record or beneficially by its
customers for whom The Ohio Company provides fiduciary or trust services. Such
administrative support services may include, but are not limited to, (i)
processing dividend and distribution payments from the Fund on behalf of
customers; (ii) providing periodic statements to its customers showing their
positions in the Institutional Shares; (iii) arranging for bank wires; (iv)
responding to routine customer inquiries relating to services performed by The
Ohio Company; (v) providing sub-accounting with respect to the Institutional
Shares beneficially owned by The Ohio Company's customers or the information
necessary for sub-accounting; (vi) if required by law, forwarding shareholder
communications from the 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 Institutional Shares pursuant to
specific or pre-authorized instructions. In consideration of such services, the
Group, on behalf of the Fund, has agreed to pay The Ohio Company a monthly fee,
computed at the annual rate of .15% of the average aggregate net asset value of
Institutional Shares of the Fund held during the period by customers for whom
The Ohio Company has provided services under the Servicing Agreement. Any fees
paid by the Fund to Financial Institutions under the Services Plan will be borne
solely by the Institutional Shares of the Fund.
    

CUSTODIAN

         The Group has appointed The Fifth Third Bank ("Fifth Third"), 38
Fountain Square Plaza, Cincinnati, Ohio 45263, as the Fund's custodian. In such
capacity, Fifth Third will hold or arrange for the holding of all portfolio
securities and other assets acquired and owned by the Fund.

                      WHAT ARE MY RIGHTS AS A SHAREHOLDER?

         The Group was organized as an Ohio business trust on March 23, 1993.
The Group currently consists of six funds. The shares of each of the funds of
the Group, other than the two money market funds, Cardinal Government Securities
Money Market Fund ("CGSMMF") and Cardinal Tax Exempt Money Market Fund
("CTEMMF"), are currently offered in two separate classes: Investor A Shares,
otherwise


                                     - 28 -
<PAGE>   160
referred to as Investor Shares, and Investor Y Shares, otherwise referred to as
Institutional Shares. CGSMMF and CTEMMF each only have one class of shares. Each
share represents an equal proportional 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.

         Shareholders are entitled to one vote for each dollar of value invested
and a proportionate fractional vote for any fraction of a dollar invested, and
will vote in the aggregate and not by series except as otherwise expressly
required by law. For example, shareholders of the 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 accountants. However,
shareholders of the Fund will vote as a fund, and not in the aggregate with
other shareholders of the Group, for purposes of approval of amendments to the
investment advisory agreement as it relates to the Fund or any of the Fund's
fundamental policies.

   
         Overall responsibility for the management of the Fund is vested in the
Board of Trustees of the Group. See "WHO MANAGES MY INVESTMENT OF THE FUND?"
Individual Trustees are elected by the shareholders of the Group, although
Trustees may under certain circumstances fill vacancies, including vacancies
created by expanding the size of the Board. Trustees 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 Ohio law. See "ADDITIONAL INFORMATION -
Miscellaneous" in the Statement of Additional Information for further
information.
    

         An annual or special meeting of shareholders to conduct necessary
business is not required by the Declaration of Trust, the 1940 Act or other
authority except, under certain circumstances, to elect Trustees, amend the
Declaration of Trust, approve the investment advisory agreement and to satisfy
certain other requirements. To the extent that such a meeting is not required,
the Group does not intend to have an annual or special meeting.

         The Group has represented to the Commission 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 and that the Group will
assist in communications with other shareholders as required by Section 16(c) of
the 1940 Act. At such 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.


                                     - 29 -
<PAGE>   161
         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 the 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 the 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 the Fund.

         Shareholders should direct all inquiries concerning such matters to the
Transfer Agent in writing to 215 East Capital Street, Columbus, Ohio 43215, or
by calling (800) 282-9446.

         Shareholders will receive unaudited semi-annual reports describing the
investment operations of the Fund and annual financial reports audited by
independent auditors.

                       STATEMENT OF ADDITIONAL INFORMATION


                               THE CARDINAL GROUP

         The Cardinal Group (the "Group") is an open-end management investment
company which currently offers six separate diversified investment portfolios,
each with different investment objectives.

         This Statement of Additional Information contains information about The
Cardinal Fund ("TCF"), Cardinal Government Obligations Fund ("CGOF"), Cardinal
Government Securities Money Market Fund ("CGSMMF"), Cardinal Tax Exempt Money
Market Fund ("CTEMMF"), Cardinal Balanced Fund ("CBF") and Cardinal Aggressive
Growth Fund ("CAGF") (collectively, the "Funds" and individually a "Fund").

         Much of the information contained in this Statement of Additional
Information expands upon subjects discussed in the Prospectus of the respective
Fund. Capitalized terms not defined herein are defined in the Prospectuses. No
investment in Shares of a Fund should be made without first reading the
Prospectus of that Fund.

                       INVESTMENT OBJECTIVES AND POLICIES

Additional Information on Portfolio Instruments

         The following policies supplement the investment objectives and
policies of the Funds as set forth in their respective Prospectuses.

         Bank Obligations. As described in its respective Prospectus, CTEMMF,
CBF and CAGF may each invest in bank obligations consisting of 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 such Funds will be those guaranteed by
domestic and foreign banks having, at the time of investment, assets 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 banks and savings and loan
associations, if at the time of investment the depository institution has assets
in excess of $100,000,000 (as of the date of its most recently published


                                       B-1
<PAGE>   167
financial statements), or (b) the principal amount of the instrument is insured
in full by the Federal Deposit Insurance Corporation.

         Commercial Paper. Commercial paper in which each of the Funds, other
than CGSMMF, may invest consists of unsecured promissory notes issued by
corporations. Except as noted below with respect to variable amount master
demand notes, issues of commercial paper normally have maturities of less than
nine months and fixed rates of return.

         Such Funds will invest only in commercial paper which is rated at the
time of purchase within the two highest rating groups assigned by one or more
appropriate NRSROs, or if unrated, which the Adviser determines to be of
comparable quality. For a description of the rating symbols of the NRSROs, see
the Appendix.

         U.S. Government Obligations. CGOF and CGSMMF invest in, and TCF,
CTEMMF, CBF and CAGF may invest in, obligations issued or guaranteed by the U.S.
Government or its agencies or instrumentalities. 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.

         Municipal Securities. Municipal Securities which may be purchased by
CTEMMF currently can be divided into two basic groups: Municipal Notes and
Municipal Bonds.

         Municipal Notes generally provide capital for short-term needs and have
maturities of one year or less. They include:

                  1. Project Notes. Project notes are sold through the
         Department of Housing and Urban Development to raise funds for
         federally sponsored urban renewal, neighborhood development and housing
         programs. In low-income housing, proceeds from project notes are
         chiefly used for construction financing prior to permanent financing.
         In urban renewal the funds have generally been used for land
         acquisition and site improvements. (No new urban renewal projects are
         currently being undertaken as that program has been superseded by the
         Community Block Grant Program contained in the Housing and Community
         Development Act of 1974.) Project notes are issued by public bodies
         created under the laws of one of the states, territories or U.S.
         possessions and are referred to as Local Issuing Agencies. Project
         Notes generally range in maturity


                                       B-2
<PAGE>   168
         from three months to one year. While they are the primary obligations
         of the public housing agencies or the local urban renewal agencies
         which have issued them, they are also secured by the full faith and
         credit of the U.S. Government. Payment by the United States pursuant to
         its full faith and credit obligation does not impair the tax-exempt
         character of the income from project notes.

                  2. Tax Anticipation Notes. Tax anticipation notes are issued
         by state and local governments in anticipation of collection of taxes
         to finance the current operations of such governments. The notes are
         generally payable only from tax collections and often only from the
         proceeds of the specific tax levy whose collection they anticipate.

                  3. Revenue Anticipation Notes. Revenue anticipation notes are
         issued by governmental entities in anticipation of revenues to be
         received later in the then current fiscal year.

                  4. Bond Anticipation Notes. Bond anticipation notes are issued
         in anticipation of a later issuance of bonds and are usually payable
         from the proceeds of the sale of the bonds anticipated or of renewal
         notes.

                  5. Construction Loan Notes. Construction loan notes, issued to
         provide construction financing for specific projects, are often
         redeemed after the projects are completed and accepted with funds
         obtained from the Federal Housing Administration under "Fannie Mae"
         (Federal National Mortgage Association) or "Ginnie Mae" (Government
         National Mortgage Association).

                  6. Tax-Exempt Commercial Paper. Tax-exempt commercial paper is
         issued by state and local governments and agencies thereof to finance
         seasonal working capital needs or in anticipation of longer term
         financing. The stated maturity is 365 days or less.

         Municipal Bonds are usually issued to obtain funds for various public
purposes, to refund outstanding obligations, to meet general operating expenses
or to obtain funds to lend to other public institutions and facilities. They are
generally classified as either "general obligation" or "revenue" bonds and
frequently have maturities in excess of one year at the time of issuance,
although issues having variable interest rates with demand features may permit
CTEMMF to treat them as having maturities of less than 397 days. See "ADDITIONAL
PURCHASE AND REDEMPTION INFORMATION -- Determination of Net Asset Value" herein
and "HOW IS NET ASSET VALUE CALCULATED?" in CTEMMF's Prospectus.

                  1. General Obligation Bonds. General obligation bonds are
         issued by states, counties, regional districts, cities,


                                       B-3
<PAGE>   169
         towns and school districts for a variety of purposes including mass
         transportation, highway, bridge, school, road, and water and sewer
         system construction, repair or improvement. Payment of these bonds is
         secured by a pledge of the issuer's full faith and credit and taxing
         (usually property tax) power.

                  2. Revenue Bonds. Revenue bonds are payable solely from the
         revenues generated from the operations of the facility or facilities
         being financed or from other non-tax sources. These bonds are often
         secured by debt service reserve funds, rent subsidies and/or mortgage
         collateral to finance the construction of housing, highways, bridges,
         tunnels, hospitals, university and college buildings, port and airport
         facilities, and electric, water, gas and sewer systems.

                  3. Industrial Development Revenue and Private Activity Bonds.
         Industrial development revenue bonds and private activity bonds are
         usually issued by local government bodies or their authorities to
         provide funding for industrial facilities, privately operated housing,
         health care facilities, airports, docks and mass commuting facilities,
         certain water and sewage facilities, qualified hazardous waste
         facilities and high speed innercity rail facilities. Under prior law,
         these bonds also were issued to finance commercial facilities, sports
         facilities, convention and trade show facilities and pollution control
         facilities. Payment of principal and interest on such bonds is not
         secured by the taxing power of the governmental body. Rather, payment
         is dependent solely upon the ability of the users of the facilities
         financed by the bonds to meet their financial obligations and the
         pledge, if any, of the real and personal property financed by such
         bonds as security for payment.

         Legislation to restrict or eliminate the federal income tax exemption
for interest on certain Municipal Securities has been enacted periodically in
the recent past and additional legislation may be enacted in the future. This
legislation may adversely affect the availability of Municipal Securities for
CTEMMF's portfolio. If any such legislation has a materially adverse effect on
CTEMMF's ability to achieve its investment objectives, CTEMMF will re-evaluate
its investment objectives and submit to its shareholders for approval necessary
changes in the objectives and policies of CTEMMF.

         The Municipal Securities described above represent those which CTEMMF
currently expects to purchase. However, several new types of municipal bonds and
notes, particularly those with shorter maturities, have been introduced in
recent years and the Adviser believes that other types of municipal bonds and
notes may be offered in the future. Therefore, in order to preserve maximum
flexibility in seeking to attain its investment objectives, CTEMMF


                                       B-4
<PAGE>   170
has determined not to limit its purchase to the types of Municipal Securities
described herein, although it will purchase only municipal obligations which
have the credit characteristics described herein. In addition, CTEMMF may not
purchase any municipal bonds or notes having characteristics or terms that are
inconsistent with the investment objectives or investment policies of CTEMMF.

         Subsequent to CTEMMF's purchase of a security, it may be assigned a
lower rating or cease to be rated. In such an event the Adviser is required to
promptly reassess the credit quality of such security. If such security no
longer presents minimal credit risks or if the security is deemed to be an
"Unrated Security" or a "Second-Tier Security," within the meaning of Rule 2a-7
of the 1940 Act, and receives a rating by any NRSRO below the second highest
rating category, the Adviser is generally required to sell such security within
five business days of becoming aware of such an event.

         Variable Rate Demand Municipal Securities. Variable rate demand
Municipal Securities are tax-exempt obligations that provide for a periodic
adjustment in the interest rate paid on the securities and permit the holder to
demand payment of the unpaid principal balance plus accrued interest upon a
specified number of days' notice either from the issuer or by drawing on a bank
letter of credit or comparable guarantee issued with respect to such security.
The issuer of a variable rate demand security may have a corresponding right to
prepay in its discretion the outstanding principal of the instrument plus
accrued interest upon notice comparable to that required for the holder to
demand payment.

         The terms of the securities must provide that interest rates are
adjustable at intervals ranging from weekly up to semi-annually. The adjustments
are based upon the prime rate of a bank or other appropriate interest rate
adjustment index as provided in the respective instruments. The variable rate
demand securities purchased by CTEMMF are subject to the quality characteristics
for Municipal Securities described above. While these securities are expected to
have maturities in excess of one year, the Adviser will determine at least
monthly that such securities are of high quality. The Trustees have instructed
the Adviser to exercise its right to demand payment of principal and accrued
interest thereon, if a variable rate demand security held by CTEMMF no longer
meets the quality standards of CTEMMF, unless, of course, the security can be
sold for a greater amount in the market.

         The principal and accrued interest payable to CTEMMF on demand will be
supported by an irrevocable letter of credit or comparable guarantee of a
financial institution (generally a commercial bank) whose short-term taxable
debt meets the quality criteria for investment by CTEMMF in Municipal
Securities, except in cases where the security itself meets the credit criteria
of CTEMMF without


                                       B-5
<PAGE>   171
such letter of credit or comparable guarantee. Thus, although a variable rate
demand security may be unrated, CTEMMF will have at all times an alternate high
quality credit source to draw upon for payment with respect to such security.

         The variable rate demand securities which CTEMMF may purchase include
participation interests in variable rate securities. Such participation
interests will have, as part of the participation agreement between CTEMMF and
the selling financial institution, a demand feature which permits CTEMMF to
demand payment from the seller of the principal amount of CTEMMF's participation
plus accrued interest thereon. This demand feature always will be supported by a
letter of credit or comparable guarantee provided by the selling financial
institution. Such financial institution will retain a service and a letter of
credit fee, and a fee for issuing commitments to purchase on demand, in an
amount equal to the excess of the interest paid on the variable rate security in
which CTEMMF has a participation interest over the negotiated yield at which the
participation interest was purchased by CTEMMF. Accordingly, CTEMMF will
purchase such participation interests only when the yield to CTEMMF, net of such
fees, is equal to or greater than the yield then available on other variable
rate demand securities or short-term fixed rate tax exempt securities of
comparable quality and where the fees are reasonable in relation to the services
provided by the financial institution and the security and liquidity provided by
the letter of credit or guarantee.

         Concentration. CTEMMF may invest more than 25% of its net assets in (i)
Municipal Securities whose issuers are in the same state, (ii) Municipal
Securities, the interest upon which is paid solely from revenues of similar
projects and (iii) industrial development and pollution control revenue bonds
which are not variable rate demand Municipal Securities, i.e., Municipal
Securities which are related in such a way that an economic, business or
political development or change affecting one such Municipal Security would also
affect the other Municipal Securities; for example, Municipal Securities the
interest on which is paid from revenues of similar type projects or Municipal
Securities whose issuers are located in the same state. Provided, however, that
prior to CTEMMF's so investing its net assets CTEMMF will amend its Prospectus
to disclose such practice. The District of Columbia, each state, each of its
political subdivisions, agencies, instrumentalities and authorities, and each
multi-state agency of which a state is a member, is a separate "issuer" as that
term is used in this Statement of Additional Information and in CTEMMF's
investment restrictions contained in its Prospectus. The identification of the
"issuer" depends on the terms and conditions of the security. When the assets
and revenues of an agency, authority, instrumentality or other political
subdivision are separate from those of the government creating the subdivision
and the security is supported only by the assets and revenues of the
subdivision, such subdivision would be deemed to be the sole


                                       B-6
<PAGE>   172
"issuer." Similarly, in the case of an industrial development or pollution
control revenue bond, if that bond is supported only by the assets and revenues
of the nongovernmental user, then such nongovernmental user would be deemed to
be the sole "issuer." If, however, in either case, the creating government or
some other entity guarantees a security, such a guarantee would be considered a
separate security and must be separately valued.

         When-Issued and Delayed-Delivery Securities. CGOF, CGSMMF, CTEMMF and
CBF may each purchase securities on a "when-issued" or "delayed-delivery" basis
(i.e., for delivery beyond the normal settlement date at a stated price and
yield). When a Fund agrees to purchase securities on a "when-issued" or
"delayed-delivery" basis, such Fund's custodian will set aside in a separate
account cash or liquid portfolio securities equal to the amount of the
commitment. Normally, the custodian will set aside portfolio securities to
satisfy the purchase commitment, and in such a case, the Fund may be required
subsequently to place additional assets in the separate account in order to
assure that the value of the account remains equal to the amount of such Fund's
commitment. It may be expected that a Fund's net assets will fluctuate to a
greater degree when it sets aside portfolio securities to cover such purchase
commitments than when it sets aside cash. In addition, because a Fund will set
aside cash or liquid portfolio securities to satisfy its purchase commitments in
the manner described above, such Fund's liquidity and the ability of the Adviser
to manage it might be affected in the event its commitments to purchase
"when-issued" or "delayed-delivery" securities ever exceeded 25% of the value of
its assets. Under normal market conditions, however, neither CGOF's, CGSMMF's,
CTEMMF's nor CBF's commitments to purchase "when-issued" or "delayed-delivery"
securities will exceed 25% of the value of its assets.

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

         Mortgage-related Securities. CBF may, consistent with its investment
objectives and policies, invest in mortgage-related securities issued or
guaranteed by the U.S. Government or its agencies or instrumentalities. CBF may,
in addition, invest in mortgage-related securities issued by nongovernmental
entities; provided, however, that to the extent CBF purchases mortgage-related
securities from such issuers which may, solely for purposes of Section 12 of the
1940 Act, be deemed to be investment companies, CBF's investment in such
securities will be subject to


                                       B-7
<PAGE>   173
the limitations on its investment in investment company securities set forth
below in its investment restrictions.

         Mortgage-related securities, for purposes of CBF's Prospectus and this
Statement of Additional Information, 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. 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 CBF 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 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 CBF. 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 CBF will receive when
these amounts are reinvested.

         CBF may invest in mortgage-related securities which are collateralized
mortgage obligations structured on pools of mortgage pass-through certificates
or mortgage loans. Collateralized mortgage obligations will be purchased only if
rated in the four highest bond rating categories assigned by an appropriate
NRSRO or, if unrated, which the Adviser deems to present attractive
opportunities and are of comparable quality.

         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


                                       B-8
<PAGE>   174
   
the Department of Housing and Urban Development. GNMA certificates also are
supported by the authority of GNMA to borrow funds from the U.S. Treasury to
make payments under its guarantee. Mortgage-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 FNMA and are not backed by or entitled to the full faith and
credit of the United States. 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").
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 FHLMC. FHLMC guarantees either ultimate
collection or timely payment of all principal payments on the underlying
mortgage loans. When FHLMC does not guarantee timely payment of principal, FHLMC
may remit the amount due on account of its guarantee of ultimate payment of
principal at any time after default on an underlying mortgage, but in no event
later than one year after it becomes payable.
    

         Other Asset-Backed Securities. CBF may also invest in interests in
pools of receivables, such as motor vehicle installment purchase obligations
(known as Certificates of Automobile Receivables or CARS) and credit card
receivables (known as Certificates of Amortizing Revolving Debts or CARDS). 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 CBF only when
rated in one of the four highest rating categories by an appropriate NRSRO at
the time of purchase.

         The development of these asset-backed securities is at an early state
compared to mortgage backed securities. While the


                                       B-9
<PAGE>   175
market for asset-backed securities is becoming increasingly liquid, the market
for mortgage backed securities issued by certain private organization and
non-mortgage backed securities is not as well developed. The Adviser will limit
purchases of asset-backed securities to securities that are deemed to be readily
marketable by the Adviser at the time of purchase.

         Asset-backed securities held by CBF arise through the grouping by
governmental, government-related and private organizations of loans, receivables
and other assets originated by various lenders. Interests in pools of these
assets differ from other forms of debt securities, which normally provide for
periodic payment of interest in fixed amounts with principal paid at maturity or
specified call dates. Instead, asset-backed securities provide periodic payments
which generally consist of both interest and principal payments.

         The estimated life of an asset-backed security may vary with the
prepayment experience with respect to the underlying debt instruments. The rate
of such prepayments, and hence the life of an asset-backed security, will be a
function of current market interest rates and other economic and demographic
factors. Since prepayment experience can vary, asset-backed securities may be a
less effective vehicle for locking in high long-term yields.

         Securities of Other Investment Companies. Each Fund may invest in
securities issued by other investment companies. Each Fund 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; and (c) not more than 3% of the outstanding
voting stock of any one investment company will be owned by such Fund. 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 such Fund bears directly in connection with its own operations.
Investment companies in which TCF, CGOF, CBF and CAGF may invest may also impose
a sales or distribution charge in connection with the purchase or redemption of
their shares and other types of commissions or charges. Such charges will be
payable by such Fund and, therefore, will be borne directly by shareholders.

         Income Participation Loans. CBF may make or acquire participation in
privately negotiated loans to borrowers. Frequently, such loans have variable
interest rates and may be backed by a bank letter of credit; in other cases they
may be unsecured. Such transactions may provide an opportunity to achieve higher
yields than those that may be available from other securities offered and sold
to the general public.


                                      B-10
<PAGE>   176
         Privately arranged loans, however, will generally not be rated by a
credit rating agency and will normally be liquid, if at all, only through a
provision requiring repayment following demand by the lender. Such loans made by
CBF may have a demand provision permitting such Fund to require repayment within
seven days. Participation in such loans, however, may not have such a demand
provision and may not be otherwise marketable. To the extent these securities
are not readily marketable, they will be subject to CBF's 15% limitation on
investments in illiquid securities. Recovery of an investment in any such loan
that is illiquid and payable on demand will depend on the ability of the
borrower to meet an obligation for full repayment of principal and payment of
accrued interest within the demand period, normally seven days or less (unless
such Fund determines that a particular loan issue, unlike most such loans, has a
readily available market). As it deems appropriate, the Group's Board of
Trustees will establish procedures to monitor the credit standing of each such
borrower, including its ability to honor contractual payment obligations.

         CBF will purchase income participation loans only if such instruments
are, in the opinion of the Adviser, of comparable quality to securities rated
within the four highest rating groups assigned by an applicable NRSRO.

         Repurchase Agreements. Securities held by each of the Funds may be
subject to repurchase agreements. Under the terms of a repurchase agreement, a
Fund would acquire securities from member banks of the Federal Reserve System
and registered broker-dealers which the Adviser 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 at all times the value
of collateral held pursuant to the agreement at not less than the repurchase
price (including accrued interest). In the event of a bankruptcy or other
default of a seller of a repurchase agreement, the Fund could experience both
delays in liquidating the underlying securities and losses, including: (a)
possible decline in the value of the underlying securities during the period
while the Fund seeks to enforce its rights thereto; (b) possible subnormal
levels of income and lack of access to income during this period; and (c)
expenses of enforcing its rights. Additionally, there is no controlling legal
precedent confirming that the 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 the Fund's securities
subject to repurchase agreements and under federal laws, a court of competent
jurisdiction would rule in favor of the Group


                                      B-11
<PAGE>   177
if presented with the question. Securities subject to repurchase agreements will
be held by the Group'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. CTEMMF is permitted to enter into
reverse repurchase agreements for temporary or emergency non-investment purposes
in an amount not exceeding (together with other borrowings) 5% of the value of
CTEMMF's assets at the time of entering into the agreement. CTEMMF, however, has
not entered into such agreements in the past and does not intend to enter into
such agreements in the foreseeable future.

         Foreign Investment. Investment in foreign securities is subject to
special investment risks that differ in some respects from those related to
investments in securities of U.S. domestic issuers. Since investments in the
securities of foreign issuers may involve currencies of foreign countries, a
Fund may be affected favorably or unfavorably by changes in currency rates and
in exchange control regulations and may incur costs in connection with
conversions between various currencies.

         Since foreign companies are not subject to uniform accounting, auditing
and financial reporting standards, practices and requirements comparable to
those applicable to U.S. companies, there may be less publicly available
information about a foreign company than about a U.S. company. Securities of
many foreign companies are less liquid and more volatile than securities of
comparable U.S. companies.

         In addition, with respect to certain foreign countries, there is the
possibility of expropriation or confiscatory taxation, political or social
instability, or diplomatic developments which could affect a Fund's investments
in those countries. Moreover, individual foreign economies may differ favorably
or unfavorably from the U.S. economy in such respects as growth of gross
national product, rate of inflation, capital reinvestment, resource
self-sufficiency and balance of payments position.

         TCF, CBF and CAGF will acquire such securities only when the Adviser
believes the risks associated with such investments are minimal.

         Options Trading. Each of TCF, CGOF, CBF and CAGF may purchase put and
call options. A call option gives the purchaser of the option the right to buy,
and a writer has the obligation to sell, the underlying security at the stated
exercise price at any time prior to the expiration of the option, regardless of
the market price of the security. The premium paid to the writer is
consideration for undertaking the obligations under the option contract. A put
option gives the purchaser the right to sell the


                                      B-12
<PAGE>   178
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.
Put and call options purchased by such Funds will be valued at the last sale
price, or in the absence of such a price, at the mean between bid and asked
price.

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

         TCF and CGOF may also purchase or sell index options. Index options (or
options on securities indices) are similar in many respects to options on
securities except that an index option gives the holder the right to receive,
upon exercise, cash instead of securities, if the closing level of the
securities index upon which the option is based is greater than, in the case of
a call, or less than, in the case of a put, the exercise price of the option.

   
         Medium-Grade Debt Securities. As stated in the Prospectuses for CBF and
CAGF, CBF and CAGF may invest in securities within the four highest rating
groups assigned by an appropriate NRSRO (e.g. S&P and Moody's), including
securities rated BBB by S&P or Baa by Moody's or, if unrated, judged by the
Adviser to be of comparable quality ("Medium-Grade Securities").
    

         As with other fixed-income securities, Medium-Grade Securities are
subject to credit risk and market risk. Market risk relates to changes in a
security's value as a result of changes in interest rates. Credit risk relates
to the ability of the issuer to make payments of principal and interest.
Medium-Grade Securities are considered by Moody's to have speculative
characteristics.

         Medium-Grade Securities are generally subject to greater credit risk
than comparable higher-rated securities because issuers are more vulnerable to
economic downturns, higher interest rates or adverse issuer-specific
developments. In addition, the prices of Medium-Grade Securities are generally
subject to greater market risk and therefore react more sharply to changes in
interest rates.


                                      B-13
<PAGE>   179
The value and liquidity of Medium-Grade Securities may be diminished by adverse
publicity and investor perceptions.

   
         Because certain Medium-Grade Securities are traded only in markets
where the number of potential purchasers and sellers, if any, is limited, the
ability of a Fund to sell such securities at their fair value either to meet
redemption requests or to respond to changes in the financial markets may be
limited.

         Particular types of Medium-Grade Securities may present special
concerns. The prices of payment-in-kind or zero-coupon securities may react more
strongly to changes in interest rates than the prices of other Medium-Grade
Securities. Some Medium-Grade Securities in which CBF and CAGF may invest may
be subject to redemption or call provisions that may limit increases in market
value that might otherwise result from lower interest rates while increasing the
risk that such Fund may be required to reinvest redemption or call proceeds
during a period of relatively low interest rates.
    

         The credit ratings issued by NRSROs are subject to various limitations.
For example, while such ratings evaluate credit risk, they ordinarily do not
evaluate the market risk of Medium-Grade Securities. In certain circumstances,
the ratings may not reflect in a timely fashion adverse developments affecting
an issuer. For these reasons, the Adviser conducts its own independent credit
analysis of Medium-Grade Securities.

         Futures Contracts. As discussed in the Prospectuses of the TCF, CGOF,
CBF and CAGF, each of those Funds may enter into futures contracts. This
investment technique is designed primarily to hedge against anticipated future
changes in market conditions which otherwise might adversely affect the value of
securities which a Fund holds or intends to purchase. For example, when interest
rates are expected to rise or market values of portfolio securities are expected
to fall, a Fund can seek through the sale of futures contracts to offset a
decline in the value of its portfolio securities. When interest rates are
expected to fall or market values are expected to rise, a Fund, through the
purchase of such contracts, can attempt to secure better rates or prices for the
Fund than might later be available in the market when it effects anticipated
purchases.

         The acquisition of put and call options on futures contracts will,
respectively, give a Fund the right (but not the obligation), for a specified
price, to sell or to purchase the underlying futures contract, upon exercise of
the option, at any time during the option period.

         Futures transactions involve brokerage costs and require a Fund to
segregate liquid assets, such as cash, U.S. Government securities or other
liquid high grade debt obligations, to cover


                                      B-14
<PAGE>   180
its performance under such contracts. A Fund may lose the expected benefit of
futures transactions if interest rates, securities prices or foreign exchange
rates move in an unanticipated manner. Such unanticipated changes may also
result in poorer overall performance than if the Fund had not entered into any
futures transactions. In addition, the value of a Fund's futures positions may
not prove to be perfectly or even highly correlated with the value of its
portfolio securities, limiting the Fund's ability to hedge effectively against
interest rate and/or market risk and giving rise to additional risks. There is
no assurance of liquidity in the secondary market for purposes of closing out
futures positions.

         Regulatory Restrictions. To the extent required to comply with
Securities and Exchange Commission Release No. IC-10666, when purchasing a
futures contract or writing a put option, a Fund will maintain in a segregated
account cash or liquid high-grade securities equal to the value of such
contracts.

         To the extent required to comply with Commodity Futures Trading
Commission Regulation 4.5 and thereby avoid being classified as a "commodity
pool operator," a Fund will not enter into a futures contract or purchase an
option thereon if immediately thereafter the initial margin deposits for futures
contracts held by such Fund plus premiums paid by it for open options on futures
would exceed 5% of such Fund's total assets. A Fund will not engage in
transactions in financial futures contracts or options thereon for speculation,
but only to attempt to hedge against changes in market conditions affecting the
values of securities which such Fund holds or intends to purchase. When futures
contracts or options thereon are purchased to protect against a price increase
on securities intended to be purchased later, it is anticipated that at least
25% of such intended purchases will be completed. When other futures contracts
or options thereon are purchased, the underlying value of such contracts will at
all times not exceed the sum of: (1) accrued profit on such contracts held by
the broker; (2) cash or high quality money market instruments set aside in an
identifiable manner; and (3) cash proceeds from investments due in 30 days.

Investment Restrictions

         Each Fund's investment objectives are fundamental policies and as such
may not be changed without a vote of the holders of a majority of that Fund's
outstanding Shares. In addition, the following investment restrictions of the
Funds may be changed only by a vote of a majority of the outstanding Shares of a
Fund (as defined under "ADDITIONAL INFORMATION - Vote of a Majority of the
Outstanding Shares" in this Statement of Additional Information).


                                      B-15
<PAGE>   181
         In addition to the investment restrictions set forth in their
respective Prospectuses, each of TCF, CGOF, CBF and CAGF may not:

         1. Purchase securities on margin, except for use of short-term credit
necessary for clearance of purchases of portfolio securities and except as may
be necessary to make margin payments in connection with derivative securities
transactions;

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

         3. Purchase or sell real estate (although investments in marketable
securities of companies engaged in such activities and securities secured by
real estate or interests therein are not prohibited by this restriction).

         4. Purchase or sell commodities or commodities contracts, except to the
extent disclosed in the current Prospectus of the Fund.

         In addition, CGOF may not:

         1. Purchase participations or other direct interests in oil, gas, or
other mineral exploration or development programs; or

         2. Mortgage, pledge, hypothecate or, in any other manner, transfer as
security for indebtedness any security owned by a Fund, except as may be
necessary in connection with permissible borrowings, in which event such
mortgaging, pledging or hypothecating may not exceed 5% of the Fund's assets,
valued at cost and except that the deposit of assets in escrow in connection
with writing covered call options will not be deemed to be the mortgage, pledge,
hypothecation or transfer of assets as security described above.

         CGSMMF will not:

         1. Pledge, mortgage or hypothecate its assets, except that to secure
borrowings permitted for temporary or emergency non-investment purposes, the
Trust may pledge securities having a market value at the time of pledge not
exceeding 15% of its total assets (so long as certain state law restrictions are
applicable, the market value of securities subject to any such pledge will not
exceed 10% of the market value of the Trust's total assets);

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


                                      B-16
<PAGE>   182
         3. Purchase or sell real estate or real estate mortgage loans;

         4. Purchase commodities or commodities contracts;

         5. Purchase participations or other direct interests in oil, gas or
other mineral exploration or development programs; or

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

         CTEMMF will not:

         1. Pledge, mortgage or hypothecate its assets, except that to secure
permitted borrowings it may pledge securities having a market value at the time
of pledge not exceeding 15% of the Trust's total assets; provided, however, so
long as certain state law restrictions are applicable, the market value of
securities subject to any such pledge will not exceed 10% of the market value of
the Trust's total assets;

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

         3. Purchase or sell real estate, although the Trust may invest in
Municipal Securities or temporary investments secured by interests in real
estate;

         4. Purchase or sell commodities or commodity contracts;

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

         6. Write, purchase or sell put or call options, except to the extent
that securities subject to a demand obligation or stand- by commitment may be
acquired;

         7. Purchase participations or other direct interests in oil, gas, or
other mineral exploration or development programs; or

         8. Purchase securities which are not Municipal Securities and the
income from which is subject to federal income tax, if such purchase would cause
more than 20% of the Trust's total assets to be invested in such securities.

         The following additional investment restrictions may be changed without
the majority vote of the outstanding Shares of any of the Funds. Each Fund may
not:


                                      B-17
<PAGE>   183
         1. Purchase securities of other investment companies, except (a) in
connection with a merger, consolidation, acquisition or reorganization, and (b)
to the extent permitted by the 1940 Act or pursuant to any exemptions therefrom;

         2. Engage in any short sales;

         3. Invest more than 15% of the Fund's total assets in securities which
are restricted as to disposition; or

         4. Purchase or retain securities of any issuer if the officers and
trustees of the Group and the officers and directors of its investment adviser,
who each owns beneficially more than 1/2 of 1% of the outstanding securities of
such issuer, together own beneficially more than 5% of such securities.

         In addition, each of TCF, CBF and CAGF has the following nonfundamental
investment restrictions: each such Fund may not (1) mortgage or hypothecate the
Fund's assets in excess of one-third of the Fund's total assets, (2) purchase
participations or direct interests in oil, gas or other mineral exploration or
development programs (although investments by the Fund in marketable securities
of companies engaged in such activities are not prohibited by this restriction),
or (3) invest more than 10% of the Fund's total assets in securities of issuers
which, together with any predecessors, have a record of less than three years'
continuous operation.

   
         If a percentage restriction or requirement set forth above is met at
the time of investment, a later increase or decrease in such percentage
resulting from a change in net asset value will not be considered a violation of
the policy. However, should a change in net asset value or other external events
cause a Fund's investments in illiquid securities to exceed the limitation in
its non-fundamental policy as set forth in its Prospectus, the Fund will act to
cause the aggregate amount of illiquid securities to come within such limit as
soon as reasonably practicable. In such an event, however, the Fund would not be
required to liquidate any portfolio securities where the Fund would suffer a
loss on the sale of such securities.
    

         The Group has represented to the California Department of Corporations
on behalf of each of the Funds that, in order to comply with applicable
regulations, each Fund may acquire or retain securities of other open-end
management investment companies only if such investments are made in open-end
management investment companies sold with no sales commission and the Fund's
investment adviser waives its management fee with respect to such investments.
The Group intends to comply with this undertaking with respect to a Fund for so
long as such Fund has its Shares registered for sale in the State of California
or such representation is required by the California Department of Corporations.

         The Group has represented to the Texas State Securities Board on behalf
of each of TCF, CBF and CAGF that each such Fund will limit its investments in
warrants, valued at the lower of cost or market, to no more than 5% of the value
of its net assets. Included within such amount (but not in excess of 2% of the
value of such Fund's net assets) are warrants which are not listed on the New
York or American Stock Exchanges. For purposes of this limitation, warrants
acquired in units or attached to other securities will be deemed to be without
value. The Group has also represented to the Texas State Securities Board on
behalf of each of CBF and CAGF that neither Fund may purchase or sell interests
in real estate limited partnerships, although investments in readily marketable
interests in real estate investment trusts or readily marketable securities of
companies or limited partnerships which invest in real estate are not
prohibited.

         The Group intends to comply with these representations on behalf of a
Fund for so long as such Fund has its Shares registered for sale in the state to
which such representations were made.

Portfolio Turnover

         The portfolio turnover rate for each Fund is calculated by dividing the
lesser of that Fund's purchases or sales of portfolio securities for the year by
the monthly average value of the portfolio securities. The Commission requires
that the calculation exclude all securities whose remaining maturities at the
time of acquisition were one year or less.

         Because CGSMMF and CTEMMF intend 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 portfolio turnover rate, the
portfolio turnover with respect to each of CGSMMF and CTEMMF is expected to be
zero percent for regulatory purposes. For each of the other Funds, the portfolio
turnover rates for the fiscal years ended September 30, 1996 and 1995 were as
follows:

         For such Funds, the portfolio turnover rate may vary greatly from year
to year as well as within a particular year, and may also be affected by cash
requirements for redemptions of Shares. Portfolio turnover will not be a
limiting factor in making investment decisions.

                                   THE ADVISER

        The Group has entered into an Investment Advisory and Management
Agreement dated as of June 18, 1993, as amended January 10, 1996 (the
"Investment Advisory Agreement"), with Cardinal Management Corp. (the
"Adviser"). Pursuant to the Investment Advisory Agreement, the Adviser has
agreed to provide investment advisory and management services as described in
the Prospectuses of the Funds. As compensation for such services, facilities and
expenses, the Adviser receives a fee (1) from each of CGOF, CGSMMF and CTEMMF,
computed and accrued daily and paid monthly, based on an annual rate of .50% of
the daily net asset value of that Fund; (2) from TCF, computed and accrued daily
and paid monthly, based on an annual rate of 0.60% of the daily net asset value
of TCF; and (3) from each of CBF and CAGF, computed and accrued daily and paid
monthly, based on an annual rate of .75% of the daily net asset value of that
Fund.

        Prior to the effective date of the Reorganization, the Adviser provided
investment advisory and management services to Cardinal Government Obligations
Fund, CGST and CTEMT and received a fee at the same annual rate for such
services as described above for CGOF, CGSMMF and CTEMMF, respectively. The Ohio
Company, prior to the effective date of the Reorganization, provided investment
advisory services to TCFI, and received a fee for such services based on an
annual rate of .50% of the daily net value of such Fund.

        For the fiscal years ended September 30, 1996, 1995 and 1994, the

         The Adviser is a wholly owned subsidiary of The Ohio Company, an
investment banking firm organized in 1925. Descendants of H. P. and R. F. Wolfe,
deceased, and members of their families, through their possession of a majority
of the voting stock, may be considered controlling persons of The Ohio Company.
H. Keith Allen is an officer and director of The Ohio Company. Frank W. Siegel
and James M. Schrack II are each officers of The Ohio Company.

        Unless sooner terminated, the Investment Advisory Agreement with respect
to a Fund continues for successive one-year periods ending June 18 of each year
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 that Fund (as
defined under "ADDITIONAL INFORMATION -- Vote of a Majority of the Outstanding
Shares" below), 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 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
the Adviser. 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 the Adviser shall not be
liable for any error of judgment or mistake of law or for any loss suffered by
the Group 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 compensation for services or a loss resulting from willful
misfeasance, bad faith, or negligence on the part of the


                                      B-25
<PAGE>   191
Adviser in the performance of its duties, or from negligent disregard by the
Adviser of its duties and obligations thereunder.

                             PORTFOLIO TRANSACTIONS

        Pursuant to the Investment Advisory Agreement, the Adviser, subject to
the policies established by the Board of Trustees of the Group and in accordance
with the Funds' investment restrictions and policies, is responsible for each
Fund's portfolio decisions and the placing of the Funds' portfolio transactions.
Purchases and sales of portfolio securities which are debt securities usually
are principal transactions in which such 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. Transactions 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, the Group, where possible, will deal directly with
dealers who make a market in the securities involved except in those
circumstances where better price and execution are available elsewhere.

   
        For the fiscal years ended September 30, 1996, 1995 and 1994 the
brokerage fees incurred by each of TCF (including its predecessor, TCFI, prior
to the Reorganization), CBF and CAGF are set forth in the following table. None
of those commissions were paid to The Ohio Company, and during such periods,
none of CGOF, CGSMMF or CTEMMF (nor any of their predecessors prior to the
Reorganization) incurred any brokerage commissions.

</TABLE>
    


        In executing such transactions, the Adviser seeks to obtain the best net
results for a Fund taking into account such factors as price (including the
applicable brokerage commission or dealer spread), size of order, difficulties
of execution and operational facilities of the firm involved and the firm's risk
in positioning a block of securities. While the Adviser generally seeks
reasonably competitive commission rates, for the reasons stated in the prior
sentence, a Fund will not necessarily be paying the lowest commission or spread
available.


                                      B-26
<PAGE>   192
   
        The Adviser may consider provision of research, statistical and other
information to the Group, a Fund or the Adviser in the selection of qualified
broker-dealers who effect portfolio transactions for a Fund so long as the
Adviser's ability to obtain the best net results for portfolio transactions of
that Fund is not diminished. Such research services include supplemental
research, securities and economic analyses, and statistical services and
information with respect to the availability of securities or purchasers or
sellers of securities. Such research services may also be useful to the Adviser
in connection with its services to other clients. Similarly, research services
provided by brokers serving such other clients may be useful to the Adviser in
connection with its services to a Fund. Although this information is useful to a
Fund and the Adviser, except as described below, it is not possible to place a
dollar value on it. It is the opinion of the Board of Trustees and the Adviser
that the review and study of this information will not reduce the overall cost
to the Adviser of performing its duties to the Funds under the Investment
Advisory Agreement. The Group is not authorized to pay brokerage commissions
which are in excess of those which another qualified broker would charge solely
by reason of brokerage and research services provided.

        The Group has authorized the Adviser to place brokerage transactions
through Pershing and Company, a division of Donaldson, Lufkin & Jenrette, in
return for Lipper Data information prepared for the Group's Trustees relating to
information on fees and expenses of other mutual funds. However, such brokerage
transactions are subject to the requirements as to execution and price described
above.
    

        Investment decisions for a Fund are made independently from those for
another Fund of the Group or any other investment company or account managed by
the Adviser. Any such other Funds, investment company or account may also invest
in the same securities as a Fund. When a purchase or sale of the same security
is made at substantially the same time on behalf of one Fund and


                                      B-27
<PAGE>   193
another Fund, investment company or account, the transaction will be averaged as
to price and available investments will be allocated as to amount in a manner
which the Adviser believes to be equitable to the Fund and such other Fund,
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 that Fund. To the extent permitted by law, the Adviser may
aggregate the securities to be sold or purchased for a Fund with those to be
sold or purchased for other funds or for other investment companies or accounts
in order to obtain best execution. As provided by the Investment Advisory
Agreement, in making investment recommendations for the Group, the Adviser will
not inquire or take into consideration whether an issuer of securities proposed
for purchase or sale by the Group is a customer of the Adviser, its parent or
its subsidiaries or affiliates and, in dealing with its customers, the Adviser,
its parent, subsidiaries and affiliates will not inquire or take into
consideration whether securities of such customers are held by the Group.

   
         During the fiscal year ended September 30, 1996, none of the Funds
held any securities of its regular brokers or dealers, as defined in
Rule 10b-1 under the 1940 Act, or their parent companies.
    

        Pursuant to Investment Advisory Agreement, the Adviser also serves as
general manager and administrator to each of the Funds. The Adviser assists in
supervising all operations of each Fund (other than those performed by The Fifth
Third Bank under the Custodian Agreement and by the Adviser under the Transfer
Agency and Fund Accounting Agreement).

        The Adviser 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 each Fund and file all of a Fund's federal and state tax returns
and required tax filings other than those required to be made by each Fund's
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 Group with the Group's preparation of its Annual and
Semi-Annual Reports to Shareholders and its Registration Statement (on Form N-1A
or any replacement therefor); 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 assist in all aspects of each Fund's
operations.

                 TRANSFER AND DIVIDEND AGENT AND FUND ACCOUNTANT

        The Group has entered into a Transfer Agency and Fund Accounting
Agreement dated as of June 18, 1993, as amended as of January 10, 1996 (the
"Transfer Agency Agreement"), with the Transfer Agent, pursuant to which the
Transfer Agent has agreed to act as the transfer agent, dividend disbursing
agent and administrator of plans for each Fund and to provide certain fund
accounting services for each Fund. Pursuant to the Transfer Agency Agreement,
the Transfer Agent, among other things, performs the following services in
connection with each Fund's shareholders of record: maintenance of shareholder
records for the Fund's shareholders of record; processing shareholder purchase
and redemption orders; processing transfers and exchanges of shares of the Group
on the shareholder files and records; processing dividend payments and
reinvestment; and assistance in the mailing of shareholder reports and proxy
solicitation materials. In consideration of such services each Fund has agreed
to pay the Transfer Agent monthly an annual fee equal to $18 (for TCF, CBF and
CAGF) or $21 (for CGOF, CGSMMF and CTEMMF) per shareholder account plus
out-of-pocket expenses.

        In addition, the Transfer Agency provides certain fund accounting
services to each of the Funds, including maintaining the accounting books and
records for each Fund, including journals containing an itemized daily record of
all purchases and sales of portfolio securities, all receipts and disbursements
of cash and all other debits and credits, general and auxiliary ledgers
reflecting all asset, liability, reserve, capital, income and expense accounts,
including interest accrued and interest received, and other required separate
ledger accounts; maintaining a monthly trial balance of all ledger accounts;
performing certain accounting services for each Fund, including calculation of
the net asset value per share, calculation of the dividend and capital gain
distributions, if any, and of yield, reconciliation of cash movements with such
Fund's custodian, affirmation to that Fund's custodian of all portfolio trades
and cash settlements, verification and reconciliation with that Fund's custodian
of all daily trade activity; providing certain reports; obtaining dealer
quotations, prices from a pricing service or matrix prices on all portfolio
securities in order to mark the portfolio to the market; and preparing an
interim balance sheet, statement of income and expense, and statement of changes
in net assets for each Fund. In consideration for such services, each Fund has
agreed to pay the Transfer Agent a fee, computed daily and paid periodically at
an annual rate of .03% of such Fund's average daily net assets of up to $100
million and .01% of such Fund's average daily net assets in excess of $100
million.

   
        For the fiscal years ended September 30, 1996, 1995 and 1994, the fees
incurred by each of the Funds (including their respective predecessors prior to
the Reorganization) for transfer agency and

                                    EXPENSES

        If total expenses borne by a Fund in any fiscal year exceed expense
limitations imposed by applicable state securities regulations, the Adviser will
reimburse that Fund by the amount of such excess. As of the date of this
Statement of Additional Information, the Funds are not subject to any such
limitations.

                          ADMINISTRATIVE SERVICES PLAN

        As described in the Prospectuses of TCF, CGOF, CBF and CAGF with respect
to their Institutional Shares, the Group has also adopted an Administrative
Services Plan with respect to Institutional Shares (the "Services Plan") under
which each such Fund is authorized to pay banks, broker-dealers, savings and
loan associations, trust companies (including The Ohio Company), qualified
investment advisers and certain other financial institutions which serve in a
fiduciary capacity on behalf of customers or beneficiaries (collectively,
"Financial Institutions"), to provide certain ministerial, record keeping, and
administrative support services to their customers who own of record or
beneficially Institutional Shares in a Fund. Payments to such Financial
Institutions are made pursuant to Servicing Agreements between the Group and the
Financial Institution. The Services Plan authorizes each of TCF, CGOF, CBF and
CAGF to make payments to Service Organizations in an amount, on an annual basis,
of up to 0.15% of the average daily net asset value of the Institutional Shares
that Fund. The Services Plan has been approved by the Board of Trustees of the
Group, including a majority of the Trustees who are not interested persons of
the Group (as defined in the 1940 Act) and who have no direct or indirect
financial interest in the operation of the Services Plan
    


                                      B-30
<PAGE>   196
or in any Servicing Agreements thereunder (the "Disinterested Trustees"). The
Services Plan may be terminated as to a Fund by a vote of a majority of the
Disinterested Trustees. The Trustees review quarterly a written report of the
amounts expended pursuant to the Services Plan and the purposes for which such
expenditures were made. The Services Plan may be amended by a vote of the
Trustees, provided that any material amendments also require the vote of a
majority of the Disinterested Trustees. For so long as the Services Plan is in
effect, selection and nomination of those Disinterested Trustees shall be
committed to the discretion of the Group's Disinterested Trustees. All Servicing
Agreements may be terminated at any time without the payment of any penalty by a
vote of a majority of the Disinterested Trustees. The Services Plan will
continue in effect for successive one-year periods, provided that each such
continuance is specifically approved by a majority of the Board of Trustees,
including a majority of the Disinterested Trustees.

   
        As authorized by the Services Plan, the Group has entered into a
Servicing Agreement with The Ohio Company pursuant to which The Ohio Company has
agreed to provide certain administrative support services in connection with
Institutional Shares of the Funds owned of record or beneficially by its
customers for whom The Ohio Company serves as a fiduciary. 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
Institutional Shares; (iii) arranging for bank wires; (iv) responding to routine
customer inquiries relating to services performed by The Ohio Company; (v)
providing sub-accounting with respect to the Institutional Shares beneficially
owned by The Ohio Company'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 Institutional Shares pursuant to specific or
pre-authorized instructions. In consideration of such services, the Group, on
behalf of each of TCF, CGOF, CBF and CAGF, has agreed to pay The Ohio Company a
monthly fee, computed at the annual rate of .15% of the average aggregate net
asset value of Institutional Shares of that Fund held during the period by
customers for whom The Ohio Company has provided services under the Servicing
Agreement.

dated June 18, 1993, as amended as of January 2, 1997 (the "Distribution
Agreement"). Unless otherwise terminated, the Distribution Agreement remains in
effect for successive annual periods ending on June 18 if 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 Group, 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, The Ohio Company 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 from the Group under the Distribution Agreement, but may receive
compensation under the Distribution and Shareholder Service Plan described below
with respect to sales of Investor Shares of TCF, CGOF, CBF and CAGF and retain
all or a portion of the sales charges with respect to its sales of Shares of
TCF, CGOF, CBF and CAGF.

   
        For the fiscal years ended September 30, 1996, 1995 and 1994,
commissions paid to The Ohio Company with respect to the sale of Shares of TCF,
CGOF (and their respective predecessors), CBF and CAGF, after discounts to
dealers, were $377,963, $439,190 and $1,264,115, respectively.
    

        As described in the Prospectus, the Group has adopted a Distribution and
Shareholder Service Plan with respect to Investor Shares (the "12b-1 Plan")
pursuant to Rule 12b-1 under the 1940 Act under which each of TCF, CGOF, CBF and
CAGF (collectively, the "12b-1 Funds" and individually a "12b-1 Fund") is
authorized to pay The Ohio Company, with respect to such Fund's Investor Shares,
for payments The Ohio Company makes to broker-dealers, including The Ohio
Company, banks and other institutions (with all of the foregoing organizations
being referred to as "Participating Organizations") for providing distribution
or shareholder service assistance or for distribution assistance and/or
shareholder service provided by The Ohio Company pursuant to an agreement
between The Ohio Company and the Group. Payments to such Participating
Organizations may be made pursuant to agreements entered into with The Ohio
Company. The 12b-1 Plan authorizes each 12b-1 Fund to make payments to The Ohio
Company in an amount not in excess, on an annual basis, of 0.25% of the average
daily net asset value of the Investor Shares of that 12b-1 Fund.

        As required by Rule 12b-1, the 12b-1 Plan was approved by the initial
sole shareholder of each 12b-1 Fund and by the Board of Trustees, including a
majority of the Trustees who are not interested persons of that 12b-1 Fund and
who have no direct or


                                      B-32
<PAGE>   198
indirect financial interest in the operation of the 12b-1 Plan (the "Independent
Trustees"). The 12b-1 Plan may be terminated as to a 12b-1 Fund by vote of a
majority of the Independent Trustees, or by vote of majority of the outstanding
Investor Shares of that 12b-1 Fund. Any change in the 12b-1 Plan that would
materially increase the distribution cost to a 12b-1 Fund requires Investor
shareholder approval. The Trustees review quarterly a written report of such
costs and the purposes for which such costs have been incurred. The 12b-1 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. For so long as
the 12b-1 Plan is in effect, selection and nomination of those Trustees who are
not interested persons of the Group shall be committed to the discretion of such
disinterested persons. All agreements with any person relating to the
implementation of the 12b-1 Plan with respect to a 12b-1 Fund may be terminated
at any time on 60 days' written notice without payment of any penalty, by vote
of a majority of the Independent Trustees or by a vote of the majority of the
outstanding Investor Shares of such 12b-1 Fund.

        The 12b-1 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 a 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 them to make an informed determination of whether
the 12b-1 Plan should be implemented or continued. In addition the Trustees in
approving the 12b-1 Plan must determine that there is a reasonable likelihood
that the 12b-1 Plan will benefit the 12b-1 Funds and their Investor
Shareholders.

        The Board of Trustees of the Group believes that the 12b-1 Plan is in
the best interests of the 12b-1 Funds since it encourages Fund growth and
retention of Fund assets. As a 12b-1 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 12b-1 Plan, the Group has entered into a Rule 12b-1
Agreement with The Ohio Company pursuant to which The Ohio Company has agreed to
provide certain shareholder services in connection with Investor Shares of a
12b-1 Fund purchased and held by The Ohio Company for the accounts of its
customers and Investor Shares of a 12b-1 Fund purchased and held by customers of
The Ohio Company directly, including, but not limited to, answering Shareholder
questions concerning the 12b-1 Funds, providing information to Shareholders on
their investments in the 12b-1 Funds and providing such personnel and
communication equipment as is necessary and appropriate to accomplish such
matters. In consideration of such services the Group, on behalf of each 12b-1
Fund, has agreed to pay The Ohio Company a monthly fee, computed at the annual
rate of .25% of the average aggregate net asset value of


                                      B-33
<PAGE>   199
   
Investor Shares of that 12b-1 Fund held during the period in customer accounts
for which The Ohio Company has provided services under this Agreement. For the
fiscal year ended September 30, 1996, fees earned by The Ohio Company under this
Rule 12b-1 Agreement, with respect to CBF were $32,534, with respect to CAGF
were $22,065, with respect to TCF were $226,662, and, with respect to CGOF, were
$138,195. However, The Ohio Company waived all such fees. Payments made under
the 12b-1 Plan by a 12b-1 Fund will be borne solely by the Investor Shareholders
of that Fund.
    

        In addition, The Ohio Company may enter into, from time to time, Rule
12b-1 Agreements with selected dealers pursuant to which such dealers will
provide certain Shareholder services including, but not limited to, those
discussed above.

                                    CUSTODIAN

        The Fifth Third Bank, 38 Fountain Square Plaza, Cincinnati, Ohio 45263,
has been selected to serve as the Funds' custodian pursuant to the Custody
Agreement dated June 18, 1993, as amended as of January 10, 1996. In such
capacity the custodian will hold or arrange for the holding of all portfolio
securities and other assets of the Funds.

                     LEGAL COUNSEL AND INDEPENDENT AUDITORS

   
        Baker & Hostetler, 65 East State Street, Columbus, Ohio 43215, is
counsel to the Group and will pass upon the legality of the Shares offered
thereby. The Group has selected KPMG Peat Marwick LLP, Two Nationwide Plaza,
Columbus, Ohio 43215, as independent auditors for the Funds. The financial
statements of the Funds included in this Statement of Additional Information 
have been included herein in reliance upon the report of KPMG Peat Marwick LLP,
independent auditors, given upon the authority of said firm as experts in 
accounting and auditing.

                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

   
        As of January 2, 1997, the Board of Trustees of the Group reclassified
the issued and outstanding Shares of TCF, CGOF, CBF and CAGF as Investor A
Shares, otherwise known as Investor Shares. The Board of Trustees also
authorized the issuance of Investor Y Shares, otherwise referred to as
Institutional Shares. Investor Shares and Institutional Shares of a Fund
represent the same interest in the underlying portfolio securities of that Fund
and are subject to the same expenses and fees, except that Investor Shares are
sold subject to a front-end sales charge and subject to fees payable under the
Rule 12b-1 Plan described above. Institutional Shares are sold at net asset
value without any front-end sales charge and are not subject to a Rule 12b-1 fee
but are subject to fees payable under the Administrative Services Plan described
above.
    

        The Funds' Shares are sold on a continuous basis through The Ohio
Company, principal underwriter of the Funds' Shares, at its address and number
set forth on the cover page of this Statement of Additional Information.
Investor Shares of each of TCF, CGOF, CBF and CAGF and shares of CGSMMF and
CTEMMF may also be purchased through other broker-dealers who are members of the
National Association of Securities Dealers, Inc. and have sales agreements with
The Ohio Company. Institutional Shares of TCF, CGOF, CBF and CAGF, may also be
purchased at net asset value through procedures established by The Ohio Company
in connection with the requirements of accounts for which banks, broker-dealers,
savings and loan associations, trust companies (including The Ohio Company),
qualified investment advisers and certain other financial institutions serve in
a fiduciary capacity on behalf of customers or beneficiaries (collectively,
"Financial Institutions").

   
        Based upon the value of TCF's portfolio securities and other assets and
the number of outstanding shares as of the fiscal year ended September 30, 1996,
the net asset value and redemption price per share was $13.13. The total
offering price per share was $13.74 per share (net asset value / .9550, assuming
the then current maximum sales charge of 4.5% of the offering price).

        Based upon the value of CGOF's portfolio securities and other assets and
the number of outstanding shares as of the fiscal period ended September 30,
1996, the net asset value and redemption price per share was $8.05. The total
offering price per share was $8.42 per share (net asset value / .9550, assuming
the then current maximum sales charge of 4.50% of the offering price).

        Based upon the value of CBF's portfolio securities and other assets and
the number of outstanding Shares as of the fiscal period ended September 30,
1996, the net asset value and redemption price per share was $11.86. The total
offering price per share was
    


                                      B-35
<PAGE>   201
   
$12.41 per share (net asset value / .955, assuming the then current maximum
sales charge of 4.50% of the offering price).

        Based upon the value of CAGF's portfolio securities and other assets and
the number of outstanding Shares as of the fiscal period ended September 30,
1996, the net asset value and redemption price per share was $11.31. The total
offering price per share was $11.84 per share (net asset value / .955, assuming
the then current maximum sales charge of 4.50% of the offering price).
    

        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, or
(d) 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.

        Use of the check-writing redemption procedure by shareholders of CGSMMF
and CTEMMF will be subject to the rules and regulations of The Fifth Third Bank
(the "Bank") governing checking accounts. Neither the Bank nor the Group shall
incur any liability to a participating shareholder under this procedure for not
honoring a check that exceeds the value of Shares in a shareholder's account,
for honoring checks properly drafted, for effecting redemptions pursuant to
payment thereof or for returning checks not accepted for payment. This procedure
may be terminated at any time by the Group, the Bank or the participating
shareholder. A shareholder participating in the check-writing redemption
procedure has not established a checking or other account with the Bank for the
purposes of Federal Deposit Insurance or otherwise.

Determination of Net Asset Value

        The Group values the portfolio securities of CGSMMF and CTEMMF
(collectively, the "Money Market Funds" and individually a "Money Market Fund")
using the amortized cost valuation method. This method involves valuing a
security at its cost and thereafter accruing any discount or premium at a
constant rate to maturity. By declaring these accruals to the Money Market
Funds' shareholders in the daily dividend, the value of a Money Market Fund's
assets, and, thus, its net asset value per share, will generally remain
constant. Although this method provides certainty in valuation, it may result in
periods during which the value of a Money Market Fund's securities, as
determined by amortized cost, is higher or lower than the price the Money Market
Fund would receive if it sold the securities. During such periods, the yield on
Shares of the Money Market Fund may differ somewhat from that obtained in a
similar fund with identical investments utilizing a method of


                                      B-36
<PAGE>   202
valuation based upon market prices and estimates of market prices for all of its
portfolio securities. For example, if the use of amortized cost by a Money
Market Fund resulted in a lower aggregate portfolio value on a particular day, a
prospective investor in the Money Market Fund would be able to obtain a somewhat
higher yield than would result from investment in a similar fund utilizing
solely market values, and existing investors in the Money Market Fund would
receive less investment income.

        The valuation of the Money Market Funds' portfolio securities based upon
their amortized cost and the maintenance of the Money Market Funds' per share
net asset value of $1.00 is permitted based on the Money Market Funds' adherence
to certain conditions, including maintaining a dollar-weighted average portfolio
maturity of 90 days or less and purchasing only portfolio securities having
remaining maturities of 397 days or less. The Board of Trustees has also
established procedures designed to stabilize, to the extent reasonably possible,
the Money Market Funds' net asset value per share, as computed for the purpose
of sales and redemptions, at $1.00. Such procedures include review of the Money
Market Funds' portfolio holdings by the Board of Trustees at such intervals as
it may deem appropriate to determine whether the Money Market Funds' net asset
value calculated by using available market quotations deviates from $1.00 per
Share and, if so, whether such deviation may result in material dilution or may
be otherwise unfair to existing shareholders. These procedures also include a
review by the Adviser in accordance with policies established by the Board of
Trustees not less frequently than monthly of the quality of certain Municipal
Securities having variable interest rates and demand features that permit CTEMMF
to calculate the maturity of such obligations to a point in time prior to their
stated maturity. In the event the Board of Trustees determines that deviation in
net asset value exists, the Board of Trustees will take such corrective action
as it deems necessary and appropriate, which action might include redemption of
Shares in kind, selling portfolio securities prior to maturity to realize
capital gains or losses or to shorten average portfolio maturity, withholding
dividends, reduction of the number of Shares outstanding (i.e. the declaration
of a negative dividend) or establishing a net asset value per share by using
available market quotations.

                                      TAXES

        General. Each Fund intends to qualify as a "regulated investment
company" under the Code for so long as such qualification is in the best
interest of that Fund's shareholders. In order to qualify as a regulated
investment company, a Fund must, among other things: derive 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 securities or foreign
currencies, or other income derived with respect to its business of investing in
such stocks, securities, or currencies; derive less


                                      B-37
<PAGE>   203
than 30% of its gross income from the sale or other disposition of stocks,
securities, options, future contracts or foreign currencies held less than three
months; and diversify its investments within certain prescribed limits. In
addition, to utilize the tax provisions specially applicable to regulated
investment companies, a Fund must distribute to its shareholders at least 90% of
its investment company taxable income for the year. In general, a Fund's
investment company taxable income will be its taxable income subject to certain
adjustments and excluding the excess of any net long-term capital gain for the
taxable year over the net short-term capital loss, if any, for such year.

        A non-deductible 4% excise tax is imposed on regulated investment
companies that do not distribute in each calendar year (regardless of whether
they otherwise have a non-calendar taxable year) an amount equal to 98% of their
ordinary income for the calendar year plus 98% of their capital gain net income
for the one-year period ending on October 31 of such calendar year. The balance
of such income must be distributed during the next calendar year. If
distributions during a calendar year were less than the required amount, such
Fund would be subject to a non-deductible excise tax equal to 4% of the
deficiency.

        Although each Fund expects to qualify as a "regulated investment
company" and to be relieved of all or substantially all federal income taxes,
depending upon the extent of its activities in states and localities in which
its offices are maintained, in which its agents or independent contractors are
located, or in which it is otherwise deemed to be conducting business, a Fund
may be subject to the tax laws of such states or localities. In addition, if for
any taxable year a Fund does not qualify for the special tax treatment afforded
regulated investment companies, all of its taxable income will be subject to
federal tax at regular corporate rates (without any deduction for distributions
to its shareholders). In such event, dividend distributions would be taxable to
shareholders to the extent of earnings and profits, and would be eligible for
the dividends received deduction for corporations.

        It is expected that each Fund will distribute annually to shareholders
all or substantially all of that Fund's net ordinary income and net realized
capital gains and that such distributed net ordinary income and distributed net
realized capital gains will be taxable income to shareholders for federal income
tax purposes, even if paid in additional Shares of the Fund and not in cash.

        Distribution by a Fund of the excess of net long-term capital gain over
net short-term capital loss is taxable to shareholders as long-term capital gain
in the year in which it is received, regardless of how long the shareholder has
held the Shares. Such distributions are not eligible for the dividends-received
deduction.


                                      B-38
<PAGE>   204
        Federal taxable income of individuals is subject to graduated tax rates
of 15%, 28%, 31%, 36% and 39.6%. Further, the marginal tax rate may be in excess
of 39.6%, because adjustments reduce or eliminate the benefit of the personal
exemption and itemized deductions for individuals with gross income in excess of
certain threshold amounts.

        Capital gains of individuals are subject to tax at the same rates
applicable to ordinary income; however, the tax rate on capital gains of
individuals cannot exceed 28%. Capital losses may be used to offset capital
gains. In addition, individuals may deduct up to $3,000 of net capital loss each
year to offset ordinary income. Excess net capital loss may be carried forward
to future years.

        Federal taxable income of corporations in excess of $75,000 up to $10
million is subject to a 34% tax rate; however, because the benefit of lower tax
rates on a corporation's taxable income of less than $75,000 is phased out for
corporations with income in excess of $100,000 but lower than $335,000, a
maximum marginal tax rate of 39% may result. Federal taxable income of
corporations in excess of $10 million is subject to a tax rate of 35%. Further,
a corporation's federal taxable income in excess of $15 million is subject to an
additional tax equal to 3% of taxable income over $15 million, but not more than
$100,000.

        Capital gains of corporations are subject to tax at the same rates
applicable to ordinary income. Capital losses may be used only to offset capital
gains and excess net capital loss may be carried back three years and forward
five years.

        Certain corporations are entitled to a 70% dividends received deduction
for distributions from certain domestic corporations. Each Fund will designate
the portion of any distributions which qualify for the 70% dividends received
deduction. The amount so designated may not exceed the amount received by that
Fund for its taxable year that qualifies for the dividends received deduction.

        A Fund will be required in certain cases to withhold and remit to the
United States Treasury 31% of taxable dividends paid to any shareholder who has
provided either an incorrect tax identification number or no number at all, or
who is subject to withholding by the Internal Revenue Service for failure
properly to include on his return payments of interest or dividends.

        Information set forth in the Prospectuses and this Statement of
Additional Information which relates to federal taxation is only a summary of
some of the important federal tax considerations generally affecting purchasers
of Shares of a Fund. No attempt has been made to present a detailed explanation
of the federal income tax treatment of a Fund or its shareholders and this
discussion is not intended as a substitute for careful tax planning.
Accordingly, potential purchasers of Shares of a Fund are urged to


                                      B-39
<PAGE>   205
consult their tax advisers with specific reference to their own tax situation.
In addition, the tax discussion in the Prospectuses and this Statement of
Additional Information is based on tax laws and regulations which are in effect
on the date of the Prospectuses and this Statement of Additional Information;
such laws and regulations may be changed by legislative or administrative
action.

         Specific Information Regarding CTEMMF. An exempt-interest dividend is
any dividend or part thereof (other than a capital gain dividend) paid by CTEMMF
that is derived from interest received by CTEMMF that is excluded from gross
income for federal income tax purposes, net of certain deductions, provided the
dividend is designated as an exempt-interest dividend in a written notice mailed
to shareholders not later than sixty days after the close of CTEMMF's taxable
year. The percentage of the total dividends paid by CTEMMF during any taxable
year that qualifies as exempt-interest dividends will be the same for all
shareholders receiving dividends during such year. Exempt-interest dividends
shall be treated by CTEMMF's shareholders as items of interest excludable from
their gross income for Federal income tax purposes under Section 103(a) of the
Code. However, a shareholder is advised to consult his tax adviser with respect
to whether exempt-interest dividends retain the exclusion under Section 103(a)
of the Code if such shareholder is a "substantial user" or a "related person" to
such user under Section 147(a) of the Code with respect to any of the Municipal
Securities held by CTEMMF. If a shareholder receives an exempt- interest
dividend with respect to any Share and such Share is held by the shareholder for
six months or less, any loss on the sale or exchange of such Share shall be
disallowed to the extent of the amount of such exempt-interest dividend.

        In general, interest on indebtedness incurred or continued by a
shareholder to purchase or carry Shares of CTEMMF is not deductible for federal
income tax purposes if CTEMMF distributes exempt-interest dividends during the
shareholder's taxable year. A shareholder of CTEMMF that is a financial
institution may not deduct interest expense attributable to indebtedness
incurred or continued to purchase or carry Shares of CTEMMF if CTEMMF
distributes exempt-interest dividends during the shareholder's taxable year
(except that 80% in the case of interest expense attributable to tax-exempt
obligations acquired after December 31, 1982, and prior to August 7, 1986 may be
deducted). Certain federal income tax deductions of property and casualty
insurance companies holding Shares of CTEMMF and receiving exempt-interest
dividends may also be adversely affected. In certain limited instances, the
portion of Social Security benefits received by a shareholder which may be
subject to federal income tax may be affected by the amount of tax-exempt
interest income, including exempt-interest dividends received by shareholders of
CTEMMF.

        In the unlikely event CTEMMF realizes long-term capital gains, CTEMMF
intends to distribute any realized net long-term capital gains annually. If
CTEMMF distributes such gains, CTEMMF will have


                                      B-40
<PAGE>   206
no tax liability with respect to such gains, and the distributions will be
taxable to shareholders as long-term capital gains regardless of how long the
shareholders have held the Shares. Any such distributions will be designated as
a capital gain dividend in a written notice mailed by CTEMMF to the shareholders
not later than sixty days after the close of CTEMMF's taxable year. It should be
noted, however, that capital gains are taxed like ordinary income except that
net capital gains of individuals are subject to a maximum federal income tax
rate of 28%. Net capital gains are the excess of net long-term capital gains
over net short-term capital losses. Any net short-term capital gains are taxed
at ordinary income tax rates. If a shareholder receives a capital gain dividend
with respect to any Share and then sells the Share before he has held it for
more than six months, any loss on the sale of the Share is treated as long-term
capital loss to the extent of the capital gain dividend received.

        Interest earned by individuals and corporations on certain municipal
obligations issued on or after August 8, 1986, to finance certain private
activities will be treated as a tax preference item in computing the alternative
minimum tax. It is likely that exempt-interest dividends received by
shareholders from CTEMMF will also be treated as tax preference items in
computing the alternative minimum tax to the extent that distributions by CTEMMF
are attributable to such obligations. Also, a portion of all other interest
excluded from gross income for federal income tax purposes earned by a
corporation may be subject to the alternative minimum tax as a result of the
inclusion in alternative minimum taxable income of 75% of the excess of adjusted
current earnings and profits over pre-book alternative minimum taxable income.
Adjusted current earnings and profits would include exempt-interest dividends
distributed by CTEMMF to corporate shareholders.

        For taxable years of corporations beginning before 1996, the Superfund
Revenue Act of 1986 imposes an additional tax (which is deductible for federal
income tax purposes) on a corporation at a rate of 0.12 of one percent on the
excess over $2,000,000 of such corporation's "modified alternative minimum
taxable income," which would include a portion of the exempt-interest dividends
distributed by CTEMMF to such corporation, and exempt-interest dividends
distributed to certain foreign corporations doing business in the United States
could be subject to a branch profits tax imposed by Section 884 of the Code.

        Distributions of exempt-interest dividends by CTEMMF may be subject to
state and local taxes even though a substantial portion of such distributions
may be derived from interest on obligations which, if received directly, would
be exempt from such taxes. CTEMMF will report to its shareholders annually after
the close of its taxable year the percentage and source, on a state-by-state
basis, of interest income earned on municipal obligations held by CTEMMF during
the preceding year. Shareholders are advised to


                                      B-41
<PAGE>   207
consult their tax advisers concerning the application of state and
local taxes.

                             ADDITIONAL INFORMATION

Description of Shares

        The Group is an Ohio business trust. The Group was organized on March
23, 1993, and the Group's Declaration of Trust was filed with the Secretary of
State of Ohio on March 23, 1993. The Declaration of Trust authorizes the Board
of Trustees to issue an unlimited number of Shares, which are units of
beneficial interest, without par value. The Group presently has six series of
Shares, which represent interests in each series of the Group. The Shares of
each of the Funds of the Group, other than the Money Market Funds, are divided
into four separate classes: Investor A Shares, Investor B Shares, Investor C
Shares and Investor Y Shares, which are otherwise referred to as Institutional
Shares, although currently Investor B and C Shares are not being offered. Shares
of the Money Market Funds are being offered only in one class. 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 respective Prospectus
and this Statement of Additional Information, a Fund's 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 Fund, 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 series affected by the matter. For purposes of determining whether the
approval of a majority of the outstanding shares of a series will be required in
connection with a matter, a series will be deemed to be affected by a matter
unless it is clear that the interests of each series in the matter are
identical, or that the matter does not affect any interest of the series. Under
Rule 18f-2, the approval of any amendment to the Investment Advisory Agreement
or any change in investment policy submitted to shareholders would be
effectively acted upon with respect to a series only if approved by a majority


                                      B-42
<PAGE>   208
of the outstanding shares of such series. However, Rule 18f-2 also provides that
the ratification of independent public accountants and the election of Trustees
may be effectively acted upon by shareholders of the Group voting without regard
to series.

Vote of a Majority of the Outstanding Shares

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

Miscellaneous

        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. Generally,
shareholders owning not less than 20% of the outstanding shares of the Group
entitled to vote may cause the Trustees to call a special meeting. However, the
Group has represented to the Commission that the Trustees will call a special
meeting for the purpose of considering the removal of one or more Trustees upon
written request therefor from shareholders owning not less than 10% of the
outstanding votes of the Group entitled to vote and that the Group will assist
in communications with other shareholders as required by Section16(c) of the
1940 Act. 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.

        The Group is registered with the Commission as a management investment
company. Such registration does not involve supervision by the Commission of the
management or policies of the Group.

        The Prospectuses and this Statement of Additional Information omit
certain of the information contained in the Registration Statement filed with
the Commission. Copies of such information may be obtained from the Commission
upon payment of the prescribed fee.

        The Prospectuses and this Statement of Additional Information are not an
offering of the securities herein described in any state in which such offering
may not lawfully be made. No salesman, dealer, or other person is authorized to
give any information or


                                      B-43

make any representation other than those contained in the Prospectuses and this
Statement of Additional Information.

                             PERFORMANCE INFORMATION

   
        The following performance information as of September 30, 1996, for the
Funds includes the performance of their respective predecessor funds for periods
prior to the effective date of the Reorganization. TCF and CGOF are subject to
certain additional fees that, if such fees had been imposed prior to the
Reorganization, would have affected such Funds' performance.

Yields

        For the 30-day period ended September 30, 1996, the yields of CGOF and
CBF were 6.07% and 3.22%, respectively. The yields of CGOF and CBF are computed
by annualizing net investment income per share for a recent 30-day period and
dividing that amount by a Share's maximum offering price (as of the date hereof,
4.5%) (reduced by any undeclared earned income expected to be paid shortly as a
dividend) on the last trading day of that period. Net investment income will
reflect amortization of any market value premium or discount of fixed income
securities (except for obligations backed by mortgages or other assets) and may
include recognition of a pro rata portion of the stated dividend rate of
dividend paying portfolio securities. The yield of CGOF and CBF will vary from
time to time depending upon market conditions, the composition of such Fund's
portfolio and operating expenses of the Group allocated to that Fund. These
factors and possible differences in the methods used in calculating yield should
be considered when comparing such a Fund's yield to yields published for other
investment companies and other investment vehicles. Yield should also be
considered relative to changes in the value of CGOF's and CBF's Shares and to
the relative risks associated with the investment objectives and policies of
those Funds.

        For the seven-day period ended September 30, 1996, the current yields
for CGSMMF and CTEMMF were 4.55% and 2.99%, respectively, and their effective
yields were 4.65% and 3.03%, respectively. The current (average annualized)
yield of CGSMMF and CTEMMF for any seven-day period is calculated by dividing
the average daily net income per Share earned by that Fund during the seven-day
calendar period by such Fund's average price per Share over the same period and
annualizing this quotient on a 365 day basis. For purposes of this calculation,
the daily net income reflects dividends declared on the original Share and
dividends declared on any Shares purchased with dividends on that Share. Capital
changes that are excluded from the calculation are realized gains and losses
from the sale of securities as well as unrealized appreciation and depreciation
with respect to the Fund's portfolio.
    

        The effective or compounded yield of CGSMMF and CTEMMF for any seven-day
period is computed by adding the number one to the daily


                                      B-44
<PAGE>   210
net income per Share earned by such Fund during the seven-day calendar period,
raising the sum to a power equal to 365 divided by seven, and subtracting the
number one from the result.

   
        For the seven-day period ended September 30, 1996, the tax equivalent
yield and the tax equivalent effective yield for CTEMMF were 4.95% and 5.02%,
respectively. CTEMMF's tax-equivalent yield is computed by dividing that portion
of CTEMMF's yield which is tax-exempt by 1 minus the stated income tax rate and
adding the result to that portion, if any, of CTEMMF's yield that is not
tax-exempt. CTEMMF's tax-equivalent effective yield is computed by dividing that
portion of the effective yield which is tax-exempt by 1 minus the stated income
tax rate and adding to that result the portion, if any, of CTEMMF's effective
yield that is not tax-exempt.

Calculation of Total Return

        For the one year, five year and ten year periods ended September 30,
1996, and the respective periods from commencement of operations to September
30, 1996, the average annual returns and cumulative total returns for TCF, CGOF,
CBF and CAGF were as follows:

        Each quotation of average annual total return will be computed by
finding the average annual compounded rate of return over that period which
would equate the value of an initial amount of $1,000 invested in a Fund equal
to the ending redeemable value, according to the following formula:

   
                               P(T + 1)(n) = ERV
    

        Where: P = a hypothetical initial payment of $1,000, T = average annual
total return, n = number of years, and ERV = ending redeemable value of a
hypothetical $1,000 payment at the beginning of the period at the end of the
period for which average annual


                                      B-45
<PAGE>   211
total return is being calculated assuming a complete redemption. The calculation
of average annual total return assumes the deduction of the maximum sales charge
from the initial investment of $1,000, assumes the reinvestment of all dividends
and distributions at the price stated in the then effective Prospectus on the
reinvestment dates during the period and includes all recurring fees that are
charged to all shareholder accounts assuming such Fund's average account size.
Cumulative return is computed by using average annual total return, as
calculated above, for each year of the relevant period to determine the total
return on a hypothetical initial investment of $1,000 over such period.

   
        In addition, as described in their respective Prospectuses, from time to
time CGOF and CBF may include in their sales literature and shareholder reports
a quote of a current "distribution" rate. For the 12-month period ended
September 30, 1996, CGOF's and CBF's distribution rates were 6.98% and 3.36%,
respectively. The current distribution rate is computed by dividing the total
amount of dividends per share paid by the Fund during the past twelve months by
a current maximum offering price. Under certain circumstances, such as when
there has been a change in the amount of dividend payout, or a fundamental
change in investment policies, it might be appropriate to annualize the
dividends paid over the period such changed policies were in effect, rather than
using the dividends during the past twelve months. The current distribution rate
differs from the current yield computation because it may include distributions
to shareholders from sources other than dividends and interest, such as premium
income from option writing, short-term capital gains and net equalization
credits and is calculated over a different period of time.
    

        At any time in the future, yields and total return may be higher or
lower than past yields and total return and there can be no assurance that any
historical results will continue. Investors in the Funds are specifically
advised that Share prices of TCF, CGOF, CBF and CAGF expressed as the net asset
values per share, will vary just as yields and total return will vary.

Performance Comparisons

   
        Investors may also judge the performance of a 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 such as those prepared by Dow Jones & Co., Inc., Lehman
Brothers, The Frank Russell Group, and, Standard & Poor's Corporation and to
data prepared by Lipper Analytical Services, Inc., Morningstar, Inc. and CDA

THE CARDINAL GROUP
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
 
SEPTEMBER 30, 1996
1.  ORGANIZATION
 
The Cardinal Group (the "Group") is an open-end management investment company,
sponsored by The Ohio Company ("TOC"), established as an Ohio Business Trust on
March 23, 1993. The Group is authorized to issue an unlimited number of shares
which are units of beneficial interest without par value. Before June 24, 1993
the Group had no operations other than those relating to organizational matters,
including the issuance of 5,000 shares of beneficial interest in each of
Cardinal Balanced Fund and Cardinal Aggressive Growth Fund (the "Original
Portfolios") for cash at $10.00 per share on June 4, 1993 to Cardinal Management
Corp. ("CMC"), the Group's Investment Adviser and a wholly owned subsidiary of
TOC.
 
Effective May 1, 1996 the Group acquired the assets and assumed the liabilities
of four open-end management investment companies also sponsored by TOC in
exchange for shares of corresponding portfolios of the Group. Cardinal
Government Securities Trust, Cardinal Tax Exempt Money Trust, The Cardinal Fund
Inc., and Cardinal Government Obligations Fund (collectively the "Acquired
Funds") were acquired by portfolios of the Group as follows:
 
     Cardinal Government Securities Trust was acquired by Cardinal Government
Securities Money Market Fund
 
     Cardinal Tax Exempt Money Trust was acquired by Cardinal Tax Exempt Money
Market Fund
 
     The Cardinal Fund Inc. was acquired by The Cardinal Fund
 
     Cardinal Government Obligations Fund was acquired by Cardinal Government
Obligations Fund
 
The new portfolios retained the basic investment objectives and assumed the
historical performance of the Acquired Funds.
 
2.  SIGNIFICANT ACCOUNTING POLICIES
 
The following is a summary of significant accounting policies that the Group
follows in the preparation of its financial statements and the calculation of
daily net asset values. The policies are in conformity with generally accepted
accounting principles and the Investment Company Act of 1940 (the "Act"), as
amended. The preparation of these financial statements requires the management
of the Group to make estimates and assumptions which affect the reported amounts
of assets and liabilities as of September 30, 1996 and the income and expenses
reported for the period. Actual results could differ significantly from those
estimates.
 
SECURITIES VALUATION  Investments in Cardinal Government Securities Money Market
Fund and Cardinal Tax Exempt Money Market Fund (the "money market funds") are
valued at amortized cost, which approximates the market value. Any premiums and
discounts are amortized on a straight-line method to the maturity of the
particular security. The use of the amortized cost method requires that the
money
 
                                                                     (continued)

market funds purchase only securities with a remaining maturity of 397 calendar
days or less (longer if certain maturity shortening provisions in Rule 2a-7, of
the Act, apply) and maintain a dollar weighted portfolio maturity of 90 days or
less.
 
Investments in The Cardinal Fund, Cardinal Aggressive Growth Fund, Cardinal
Balanced Fund and Cardinal Government Obligations Fund (collectively the
"non-money market funds") listed or traded on a national securities exchange are
valued at the last sale price. Investments traded in the over-the-counter market
are valued at either the mean between the bid and ask prices or the last sale
price as may be quoted by the National Association of Securities Dealers
Automated Quotation System. If no quotations are available the portfolio
securities are valued in good faith by the Board of Trustees.
 
SECURITY TRANSACTIONS AND INVESTMENT INCOME  Security transactions are recorded
on the trade date, which is the date they are purchased or sold. Interest income
is recognized on the accrual basis. Dividend income, if any, is recognized on
the ex-dividend date. Realized gains or losses are calculated using the
First-In/First-Out (FIFO) basis.
 
REPURCHASE AGREEMENTS  It is the policy of the Group for its Custodian, Fifth
Third Bank of Cincinnati, or a third-party bank reporting to the Custodian, to
take possession of all securities pledged to the Group as collateral for the
funds loaned in repurchase agreements. Repurchase agreements entered into by the
Group must mature in seven days or less and be fully collateralized by
securities eligible for purchase by the participating portfolio. The Group may
only participate in repurchase transactions with those banks and securities
broker/dealers that meet the credit criteria established by the Board of
Trustees and monitored by CMC.
 
DEFERRED ORGANIZATIONAL COST  Costs incurred with the initial organization of
the Group have been deferred and are being amortized on a straight-line basis
over the 60 month period from the commencement of operations on June 24, 1993.
In the event that any of the initial shares of the Original Portfolios are
redeemed by CMC or any subsequent holders thereof during the 60 month
amortization period, the Group will reduce the redemption proceeds otherwise
payable by any unamortized initial organizational costs in the same proportion
as the number of initial shares of the Original Portfolios being redeemed bears
to the number of initial shares of the Original Portfolios outstanding at the
time of redemption.
 
The costs incurred with the acquisitions of the Acquired Funds have been
deferred and are being amortized over the 60 month period beginning May 1, 1996,
the effective date of the acquisitions.
 
FEDERAL INCOME TAXES  The Group has made no provision for Federal income taxes.
It is the intention of the management of the Group to comply with the provisions
of the Internal Revenue Code applicable to regulated investment companies and to
make sufficient distributions of taxable income and gains within the required
time, to relieve it from all, or substantially all, Federal income taxes.
 
                                                                     (continued)

SEPTEMBER 30, 1996
 
DISTRIBUTIONS TO SHAREHOLDERS  The money market funds and Cardinal Government
Obligations Fund declare dividends from net investment income daily and pay them
to shareholders monthly. The Cardinal Fund, Cardinal Aggressive Growth Fund and
Cardinal Balanced Fund declare and pay dividends from net investment income, if
any, quarterly. Realized capital gains, if any, are declared and paid annually
for the Group. Distributions of net investment income and realized capital gains
are determined in accordance with the Internal Revenue Code and may differ from
those calculated in accordance with generally accepted accounting principles.
For the period ended September 30, 1996, approximately $77,000 in net investment
losses for the Cardinal Aggressive Growth Fund were used to offset short-term
capital gains for Federal income tax purposes. In addition, approximately
$132,000, representing a portion of the Cardinal Aggressive Growth Fund's
redemptions during the period ended September 30, 1995 were classified as
capital gain distributions under income equalization rates allowed for Federal
income tax purposes.
 
OPTION WRITING  When a portfolio of the Group writes an option, an amount equal
to the premium received is recorded as a liability and is subsequently adjusted
to the current market value of the option written. Premiums received from
options written that expire unexercised are recognized as realized gains by the
portfolio on the expiration date. The difference, if any, between the premium
received and the amount paid in a closing transaction is also treated as a
realized gain or loss. If a written option is exercised, the premium received is
added to proceeds from sales of the underlying securities for call options
written or deducted from the cost basis of securities purchased for put options
written. The portfolios making use of option writing bear the market risk of an
unfavorable change in the price of any security/index underlying the written
option.
 
EXPENSE ALLOCATION  Expenses directly related to one of the Group's portfolios
are charged to that portfolio. Other operating expenses are allocated to the
portfolios of the Group based on their relative net assets.

                                    APPENDIX


        Commercial Paper Ratings. Commercial paper ratings of Standard & Poor's
Corporation ("S&P") are current assessments of the likelihood of timely payment
of debts having original maturities of no more than 365 days. Commercial paper
rated A-1 by S&P indicates that the degree of safety regarding timely payment is
either overwhelming or very strong. Those issues determined to possess
overwhelming safety characteristics are denoted A-1+. Commercial paper rated A-2
by S&P indicates that capacity for timely payment on issues is strong. However,
the relative degree of safety is not as high as for issues designated A-1.

         The rating Prime-1 is the highest commercial paper rating assigned by
Moody's Investors Service, Inc. ("Moody's"). Issuers rated Prime-1 (or related
supporting institutions) are considered to have a superior capacity for
repayment of short-term promissory obligations. Issuers rated Prime-2 (or
related supporting institutions) have a strong capacity for repayment of
short-term promissory obligations. This will normally be evidenced by many of
the characteristics of Prime-1 rated issuers, but to a lesser degree. Earnings
trends and coverage ratios, while sound, will be more subject to variations.
Capitalization characteristics, while still appropriate, may be more affected by
external conditions. Ample alternative liquidity is maintained.

        Commercial paper rated F-1 by Fitch Investors Service ("Fitch") is
regarded as having the strongest degree of assurance for timely payments.
Commercial paper rated F-2 by Fitch is regarded as having an assurance of timely
payment only slightly less than the strongest rating, i.e., F-1.

        The plus (+) sign is used after a rating symbol to designate the
relative position of an issuer within the rating category.

        Corporate Debt Ratings. A S&P corporate debt rating is a current
assessment of the creditworthiness of an obligor with respect to a specific
obligation. Debt rated AAA has the highest rating assigned by S&P. Capacity to
pay interest and repay principal is extremely strong. Debt rated AA has a very
strong capacity to pay interest and to repay principal and differs from the
highest rated issues only in small degree. Debt rated A has a strong capacity to
pay interest and repay principal although it is somewhat more susceptible to
adverse effects of changes in circumstances and economic conditions than debt in
higher rated categories. Debt rated BBB is regarded as having an adequate
capacity to pay interest and repay principal. Whereas it normally exhibits
adequate protection parameters, adverse economic conditions or changing
circumstances are more likely to lead to a weakened capacity to pay interest and
repay principal for debt in this category than in higher rated categories. Debt
rated BB and


                                       A-1
<PAGE>   246
B is regard as having predominantly speculative characteristics with respect to
capacity to pay interest and repay principal. BB indicates the lease degree of
speculation. While such debt will likely have some quality and protective
characteristics, these are outweighed by large uncertainties or major exposures
to adverse conditions. Debt rated BB has less near-term vulnerability to default
than other speculative issues. However, it faces major ongoing uncertainties or
exposure to adverse business, financial, or economic conditions which could lead
to inadequate capacity to meet timely interest and principal payments. The BB
rating category is also used for debt subordinated to senior debt that is
assigned an actual or implied BBB rating. Debt rated B has a greater
vulnerability to default but currently has the capacity to meet interest
payments and principal repayments. Adverse business, financial or economic
conditions will likely impair capacity or willingness to pay interest and repay
principal. The B rating category is also used for debt subordinated to senior
debt that is assigned an actual or implied BB or BB- rating.

        The following summarizes the six highest ratings used by Moody's for
corporate debt. Bonds that are rated Aaa by Moody's are judged to be of the best
quality. They carry the smallest degree of investment risk and are generally
referred to as "gilt 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. Bonds
that 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 risks appear somewhat larger than in Aaa securities. Bonds that are
rated A by Moody's possess many favorable investment attributes and are to be
considered as upper medium-grade obligations. Factors giving security to
principal and interest are considered adequate, but elements may be present
which suggest a susceptibility to impairment some time in the future. Bonds that
are rated Baa by Moody's are considered as medium grade obligations, i.e., they
are neither highly protected nor poorly secured. Interest payments and principal
security appear adequate for the present but certain protective elements may be
lacking or may be characteristically unreliable over any great length of time.
Such bonds lack outstanding investment characteristics and in fact have
speculative characteristics as well. Bonds that are rated Ba are judged to have
speculative elements; their future cannot be considered as well assured. Often
the protection of interest and principal payments may be very moderate and
thereby not well safeguarded during both good and bad times over the future.
Uncertainty of position characterizes bonds in this class. Bonds which are rated


                                       A-2
<PAGE>   247
B generally lack characteristics of the desirable investment. Assurance of
interest and principal payments or of maintenance of other terms of the contract
over any long period of time may be small.

        Moody's applies numerical modifiers (1, 2, and 3) with respect to bonds
rated Aa through B. The modifier 1 indicates that the bond being rated ranks in
the higher end of its generic rating category; the modifier 2 indicates a
mid-range ranking; and the modifier 3 indicates that the bond ranks in the lower
end of its generic rating category.

        The following summarizes the six highest long-term debt ratings by Duff.
Debt rated AAA has the highest credit quality. The risk factors are negligible
being only slightly more than for risk-free U.S. Treasury debt. Debt rated AA
has a high credit quality and protection factors are strong. Risk is modest but
may vary slightly from time to time because of economic conditions. Debt rated A
has protection factors that are average but adequate. However, risk factors are
more variable and greater in periods of economic stress. Debt rated BBB has
below average protection factors but is still considered sufficient for prudent
investment. However, there is considerable variability in risk during economic
cycles. Debt rated BB is below investment grade but deemed likely to meet
obligations when due. Present or prospective financial protection factors
fluctuate according to industry conditions or company fortunes. Overall quality
may move up or down frequently within this category. Debt rated B is below
investment grade and possesses risk that obligations will not be met when due.
Financial protection factors will fluctuate widely according to economic cycles,
industry conditions and/or company fortunes. Potential exists for frequent
changes in the rating within this category or into a higher or lower rating
grade.

        To provide more detailed indications of credit quality, the ratings from
AA to B may be modified by the addition of a plus or minus sign to show relative
standing within this major rating category.

        The following summarizes the six highest long-term debt ratings by Fitch
(except for AAA ratings, plus or minus signs are used with a rating symbol to
indicate the relative position of the credit within the rating category). Bonds
rated AAA are considered to be investment grade and of the highest credit
quality. The obligor has an exceptionally strong ability to pay interest and
repay principal, which is unlikely to be affected by reasonably foreseeable
events. Bonds rated AA are considered to be investment grade and of very high
credit quality. The obligor's ability to pay interest and repay principal is
very strong, although not quite as strong as bonds rated "AAA." Because bonds
rated in the "AAA" and "AA" categories are not significantly vulnerable to
foreseeable future developments, short-term debt of these issues is generally


                                       A-3
<PAGE>   248
rated "F-1+." Bonds rated as A are considered to be investment grade and of high
credit quality. The obligor's ability to pay interest and repay principal is
considered to be strong, but may be more vulnerable to adverse changes in
economic conditions and circumstances than bonds with higher ratings. Bonds
rated BBB are considered to be investment grade and of satisfactory credit
quality. The obligor's ability to pay interest and repay principal is considered
to be adequate. Adverse changes in economic conditions and circumstances,
however, are more likely to have adverse impact on these bonds, and therefore,
impair timely payment. The likelihood that the ratings for these bonds will fall
below investment grade is higher than for bonds with higher ratings. Bonds rated
BB are considered speculative. The obligor's ability to pay interest and repay
principal may be affected over time by adverse economic changes. However,
business and financial alternatives can be identified which could assist the
obligor in satisfying its debt service requirements. Bonds rated B are
considered highly speculative. While bonds in this class are currently meeting
debt service requirements, the probability of continued timely payment of
principal and interest reflects the obligor's limited margin of safety and the
need for reasonable business and economic activity throughout the life of the
issue.

        The following summarizes IBCA's six highest long-term debt ratings.
Obligations rated AAA are those for which there is the lowest expectation of
investment risk. Capacity for timely repayment of principal and interest is
substantial, such that adverse changes in business, economic or financial
conditions are unlikely to increase investment risk significantly. Obligations
rated AA are those for which there is a very low expectation of investment risk.
Capacity for timely repayment of principal and interest is substantial. Adverse
changes in business, economic, or financial conditions may increase investment
risk albeit not very significantly. Obligations rated A are those for which
there is a low expectation of investment risk. Capacity for timely repayment of
principal and interest is strong, although adverse changes in business, economic
or financial conditions may lead to increased investment risk. Obligations rated
BBB are those for which there is currently a low expectation of investment risk.
Capacity for timely repayment of principal and interest is adequate, although
adverse changes in business, economic, or financial conditions are more likely
to lead to increased investment risk than for obligations in other categories.
Obligations rated BB are those for which there is a possibility of investment
risk developing. Capacity for timely repayment of principal and interest exists,
but is susceptible over time to adverse changes in business, economic or
financial conditions. Obligations rated B are those for which investment risk
exists. Timely repayment of principal and interest is not sufficiently protected
against adverse changes in business, economic or financial conditions.


                                       A-4
<PAGE>   249
        The following summarizes Thomson's description of its six highest
long-term debt ratings (Thomson may include a plus (+) or minus (-) designation
to indicate where within the respective category the issue is placed). AAA is
the highest category and indicates that the ability to repay principal and
interest on a timely basis is very high. AA is the second highest category and
indicates a superior ability to repay principal and interest on a timely basis
with limited incremental risk versus issues rated in the highest category. A is
the third highest category and indicates the ability to repay principal and
interest is strong. Issues rated "A" could be more vulnerable to adverse
developments (both internal and external) than obligations with higher ratings.
BBB is the lowest investment grade category and indicates an acceptable capacity
to repay principal and interest. Issues rated "BBB" are, however, more
vulnerable to adverse developments (both internal and external) than obligations
with higher ratings. While not investment grade, the BB rating suggests that the
likelihood of default is considerably less than for lower-rated issues. However,
there are significant uncertainties that could affect the ability to adequately
service debt obligations. Issuer rated B show a higher degree of uncertainty and
therefore greater likelihood of default that higher-rated issuers. Adverse
developments could well negatively affect the payment of interest and principal
on a timely basis.

Definitions of Certain Money Market Instruments

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.

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 guaranteed
as to payment of principal and interest by the full faith and

Treasury bills, notes and bonds, and issues of agencies and instrumentalities of
the U.S. Government, provided such obligations 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.

Item 27.          Indemnification

                  Article VI, Section 6.4 of the Registrant's Declaration of
                  Trust, filed as Exhibit 1 hereto, provides for the
                  indemnification of Registrant's Trustees and officers.
                  Indemnification of the Group's principal underwriter,
                  custodian, investment adviser and manager, and transfer agent
                  is provided for, respectively, in Section 1.11 of the
                  Distribution Agreement filed as Exhibit 6(a) hereto, Section
                  8.1 of the Custody Agreement filed as Exhibit 8 hereto,
                  Section 6 of the Investment Advisory and


                                      C-11
<PAGE>   262

                  Management Agreement filed as Exhibit 5 hereto, and Section 10
                  of the Transfer Agency and Fund Accounting Agreement filed as
                  Exhibit 9(a) hereto. As of the effective date of this
                  Registration Statement, the Group will have obtained from a
                  major insurance carrier a trustees' and officers' liability
                  policy covering certain types of errors and omissions. In no
                  event will Registrant indemnify any of its trustees, officers,
                  employees or agents against any liability to which such person
                  would otherwise be subject by reason of his willful
                  misfeasance, bad faith, or gross negligence in the performance
                  of his duties, or by reason of his reckless disregard of the
                  duties involved in the conduct of his office or under his
                  agreement with Registrant. Registrant will comply with Rule
                  484 under the Securities Act of 1933 and Release 11330 under
                  the Investment Company Act of 1940 in connection with any
                  indemnification.

                  Insofar as indemnification for liability arising under the
                  Securities Act of 1933 may be permitted to trustees, officers,
                  and controlling persons of Registrant pursuant to the
                  foregoing provisions, or otherwise, Registrant has been
                  advised that in the opinion of the Securities and Exchange
                  Commission such indemnification is against public policy as
                  expressed in the Act and is, therefore, unenforceable. In the
                  event that a claim for indemnification against such
                  liabilities (other than the payment by Registrant of expenses
                  incurred or paid by a trustee, officer, or controlling person
                  of Registrant in the successful defense of any action, suit,

                  "(m) Provisions Applicable To Sub-Series. The Investor A
         Shares, Investor B Shares, Investor C Shares and Investor Y Shares of
         an applicable Series represent interests in the same portfolio of
         investments of such Series, with each Sub-Series being identical in all
         respects to each other Sub-Series of that Series, except as follows:

                  (i)      Shareholders of Investor A shares may be subject to a

                           fee and service fee payments associated with a Rule
                           12b-1 plan, as determined by the Trustees.

                  (iii)    Shareholders of Investor C Shares will not be subject
                           to a front-end sales charge but may be subject to a
                           contingent deferred sales charge and to distribution
                           fee and service fee payments associated with a Rule
                           12b-1 plan, as determined by the Trustees.

                  (iv)     Investor Y Shares will be offered to, and may be
                           held only by, banks, broker-dealers, savings and

                           behalf of customers or beneficiaries.  Shareholders
                           of Investor Y Shares will not be subject to a
                           front-end sales charge, or a contingent deferred
                           sales charge, or distribution or service fee
                           payments under a Rule 12b-1 Plan, but may be
                           subject to an administrative services fee

                           declared from time to time by the Trustees, and such
                           dividends and distributions may vary between the
                           Sub-Series to reflect differing

<PAGE>   4
                           allocations of the expenses of the Trust between the
                           Sub-Series to such extent and for such purposes as
                           the Trustees may deem appropriate.

                           Share and an Investor C Share (including a

                           reinvestment of a dividend or a distribution and
                           except where such contingent deferred sales charge
                           has been waived, shall be reduced by the amount of
                           any applicable contingent deferred sales charge
                           payable on such redemption to the distributor of
                           the Investor B Shares or Investor C Shares pursuant
                           to the terms of the issuance of such Shares (to the
                           extent consistent with the 1940 Act, or regulations
                           or exemptions thereunder) and the Trust shall
                           promptly pay to such distributor the amount of any
                           such contingent deferred sales charge.

             (vii)         (a)  Each Investor B Share, other than a share
                           purchased through the reinvestment of a dividend or

                           Shares of an eligible Trust Series occurred, if
                           such Shares were exchanged directly, or through a
                           series of exchanges of Investor B Shares of
                           eligible Trust series , for the Trust's Investor B
                           Shares being so converted (the "Conversion Date").
                           The Trustees shall adopt a resolution setting forth
                           a list of Trust Series for purposes of this
                           paragraph.

                           (b) Each Investor B Share purchased through the
                           reinvestment of a dividend or a distribution with

                           holder's sub-account so converted shall bear the same
                           relation to the total number of Investor B Shares
                           maintained in the sub-account on the Conversion Date

                           reinvestment of dividends or distributions with
                           respect to the Investor B Shares.

                           (c) The number of shares of Investor A Shares into
                           which an Investor B Share is converted pursuant to
                           paragraphs (m)(vii)(a) and (m)(vii)(b) hereof shall
                           equal the number (including for this purpose
                           fractions of a Share) obtained by dividing the net
                           asset value per share of the Investor B Shares for
                           purposes of sales and redemptions thereof at the time
                           of the calculation of the net asset value on the
                           Conversion Date by the net asset value per share of
                           the Investor A Shares for purposes of sales and
                           redemptions thereof at the time of the calculation of
                           the net asset value on the Conversion Date.

                           (d) On the Conversion Date, the Investor B Shares
                           converted into Investor A Shares will cease to accrue
                           dividends and will no longer be outstanding and the
                           rights of the holders thereof will cease (except the
                           right to receive declared but unpaid dividends to the
                           Conversion Date).

                           (e) The Trustees shall have full power and authority
                           to adopt such other terms and conditions concerning
                           the conversion of Investor B Shares to Investor A

                           inconsistent with the terms contained in this

                           applicable to the Trust.

                  (viii)   (a) At such time as Investor Y Shares shall be held
                           by a shareholder other than as described in paragraph
                           (m)(iv) hereof, such Shares shall convert
                           automatically, and without any action or choice on
                           the part of the holder thereof, into Investor A
                           Shares of the same Series, based on the relative net
                           asset values of each Sub-Series on the date of
                           conversion ("Y/A Conversion Date").

                           (b) On the Y/A Conversion Date, the Investor Y Shares
                           converted to Investor A Shares will cease to accrue
                           dividends and will no longer be outstanding and the
                           rights of the holders thereof will cease (except the
                           right to receive declared but unpaid dividends to the
                           Y/A Conversion Date).

                           (c) The Trustees shall have full power and authority
                           to adopt such other terms and conditions concerning
                           the conversion of Investor Y Shares to Investor A
                           Shares as they deem appropriate; provided such terms
                           and conditions are not inconsistent with the terms
                           contained in this paragraph (m) and subject to any

                           the rules, regulations and interpretations thereof

                             DISTRIBUTION AGREEMENT

                 June 18, 1993, as amended as of January 2, 1997

The Ohio Company
155 East Broad Street
Columbus, Ohio  43215

Ladies and Gentlemen:

         This is to confirm that, in consideration of the agreements hereinafter
contained, the undersigned, The Cardinal Group, an Ohio business trust (the
"Group"), has agreed that The Ohio Company, an Ohio corporation ("Distributor"),
shall be, for the period of this Distribution Agreement (the "Agreement"), the
distributor of the shares of beneficial interest of each class of the currently
constituted investment portfolios and any additional investment portfolios of
the Group, as each are or will be identified on Schedule A hereto (such current
investment portfolios and any additional investment portfolios together called
the "Funds"). Such shares of beneficial interest are hereinafter called
"Shares."

         1.   Services as Distributor.

         1.1  Distributor will act as agent for the distribution of the Shares
covered by the registration statement and prospectuses of the Group then in
effect under the Securities Act of 1933, as amended (the "1933 Act").

         1.2  Distributor agrees to use appropriate efforts to solicit orders 
for the sale of the Shares and will undertake such advertising and promotion as
it believes reasonable in connection with such solicitation. The Group
understands that Distributor is now and, in the future, may be the distributor
of the shares of several investment companies or series (together, "Companies")
including Companies having investment objectives similar to those of the Funds
of the Group. The Group further understands that investors and potential
investors in the Group may invest in shares of such other Companies. The Group
agrees that Distributor's duties to such Companies shall not be deemed to be in
conflict with its duties to the Group under this paragraph 1.2.

         Except as provided in Section 2 herein, Distributor shall, at its own
expense, finance appropriate activities which it deems reasonable which are
primarily intended to result in the sale of the Shares, including, but not
limited to, advertising, compensation of underwriters, dealers and sales
personnel, the printing and mailing of prospectuses to other than current
Shareholders, and the printing and mailing of sales literature.

         1.3  All activities by Distributor and its shareholders, directors,
agents, and employees as distributor of the Shares shall comply with all
applicable laws, rules and regulations, including, without limitation, all rules
and regulations made or adopted
<PAGE>   3
pursuant to the Investment Company Act of 1940 ("1940 Act") by the Securities
and Exchange Commission (the "Commission") or any securities association
registered under the Securities Exchange Act of 1934.

         1.4  Distributor will provide one or more persons, during normal
business hours, to respond to telephone questions with respect to the Group and
the Funds.

         1.5  Distributor will transmit any orders received by it for purchase
or redemption of the Shares to the transfer agent and custodian for the Funds.

         1.6  Whenever in their judgment such action is warranted by unusual
market, economic or political conditions, or by abnormal circumstances of any
kind, the Group's officers may decline to accept any orders for, or make any
sales of the Shares until such time as those officers deem it advisable to
accept such orders and to make such sales.

         1.7  Distributor will act only on its own behalf as principal if it
chooses to enter into selling agreements with selected dealers or others.

         1.8  The Group agrees at its own expense to execute any and all
documents and to furnish any and all information and otherwise to take all
actions that may be reasonably necessary in connection with the qualification of
the Shares for sale in such states as Distributor may designate.

         1.9  The Group shall furnish from time to time, for use in connection
with the sale of the Shares, such information with respect to the Funds and the
Shares as Distributor may reasonably request; and the Group warrants that the
statements contained in any such information shall fairly show or represent what
they purport to show or represent. The Group shall also furnish or cause to be
furnished to Distributor upon request with: (a) unaudited semi-annual statements
of the Funds' books and accounts prepared by or on behalf of the Group, (b)
quarterly earnings statements prepared by or on behalf of the Group, (c) a
monthly itemized list of the securities in the Funds, (d) monthly balance sheets
as soon as practicable after the end of each month, and (e) from time to time
such additional information regarding the financial condition of the Funds as
Distributor may reasonably request.

         1.10 The Group represents to Distributor that all registration
statements and prospectuses filed by the Group with the Commission under the
1933 Act with respect to the Shares have been carefully prepared in conformity
with the requirements of the 1933 Act and rules and regulations of the
Commission thereunder. As used in this agreement the terms "registration
statement" and "prospectus" shall mean any registration statement and any
prospectus and


                                       -2-
<PAGE>   4
Statement of Additional Information relating to the Funds filed with the
Commission and any amendments and supplements thereto which at any time shall
have been filed with the Commission. The Group represents and warrants to
Distributor that any registration statement and prospectus, when such
registration statement becomes effective, will contain all statements required
to be stated therein in conformity with the 1993 Act and the rules and
regulations of the Commission; that all statements of fact contained in any such
registration statement and prospectus will be true and correct when such
registration statement becomes effective; and that neither any registration
statement nor any prospectus when such registration statement becomes effective
will include an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading to a purchaser of the Shares. The Group may but shall not be
obligated to propose from time to time such amendment or amendments to any
registration statement and such supplement or supplements to any prospectus as,
in the light of future developments, may, in the opinion of the Group's counsel,
be necessary or advisable. If the Group shall not propose such amendment or
amendments and/or supplement or supplements within fifteen days after receipt by
the Group of a written request from Distributor to do so, Distributor may, at
its option, terminate this agreement. The Group shall not file any amendment to
any registration statement or supplement to any prospectus without giving
Distributor reasonable notice thereof in advance; provided, however, that
nothing contained in this agreement shall in any way limit the Group's right to
file at any time such amendments to any registration statement and/or
supplements to any prospectus, of whatever character, as the Group may deem
advisable, such right being in all respects absolute and unconditional.

         1.11 The Group authorizes Distributor and dealers to use any prospectus
in the form most recently furnished in connection with the sale of the Shares.
The Group agrees to indemnify, defend and hold Distributor, its directors,
shareholders and employees, and any person who controls Distributor within the
meaning of Section 15 of the 1933 Act free and harmless from and against any and
all claims, demands, liabilities and expenses (including the cost of
investigating or defending such claims, demands or liabilities and any counsel
fees incurred in connection therewith) which Distributor, its shareholders,
directors and employees, or any such controlling person, may incur under the
1933 Act or under common law or otherwise, arising out of or based upon any
untrue statement, or alleged untrue statement, of a material fact contained in
any registration statement or any prospectus or arising out of or based upon any
omission, or alleged omission, to state a material fact required to be stated in
either any registration statement or any prospectus or necessary to make the
statements in either thereof not misleading; provided, however, that the Group's
agreement to indemnify Distributor, its shareholders, directors or employees,
and any such controlling person shall not be deemed to


                                       -3-
<PAGE>   5
cover any claims, demands, liabilities or expenses arising out of any statements
or representations as are contained in any prospectus and in such financial and
other statements as are furnished to the Group by Distributor and used in the
answers to the registration statement or in the corresponding statements made in
the prospectus, or arising out of or based upon any omission or alleged omission
to state a material fact in connection with the giving of such information
required to be stated in such answers or necessary to make the answers not
misleading; and further provided that the Group's agreement to indemnify
Distributor and the Group's representations and warranties hereinbefore set
forth in paragraph 1.10 shall not be deemed to cover any liability to the Group
or its Shareholders to which Distributor would otherwise be subject by reason of
willful misfeasance, bad faith or gross negligence in the performance of its
duties, or by reason of Distributor's reckless disregard of its obligations and
duties under this agreement. The Group's agreement to indemnify Distributor, its
shareholders, directors and employees, and any such controlling person, as
aforesaid, is expressly conditioned upon the Group's being notified of any
action brought against Distributor, its shareholders, directors or employees, or
any such controlling person, such notification to be given by letter or by
telegram addressed to the Group at its principal office in Columbus, Ohio and
sent to the Group by the person against whom such action is brought, within 10
days after the summons or other first legal process shall have been served. The
failure to so notify the Group of any such action shall not relieve the Group
from any liability which the Group may have to the person against whom such
action is brought by reason of any such untrue, or allegedly untrue, statement
or omission, or alleged omission, otherwise than on account of the Group's
indemnity agreement contained in this paragraph 1.11. The Group will be entitled
to assume the defense of any suit brought to enforce any such claim, demand or
liability, but, in such case, such defense shall be conducted by counsel of good
standing chosen by the Group and approved by Distributor, which approval shall
not be unreasonably withheld. In the event the Group elects to assume the
defense of any such suit and retain counsel of good standing approved by
Distributor, the defendant or defendants in such suit shall bear the fees and
expenses of any additional counsel retained by any of them; but in case the
Group does not elect to assume the defense of any such suit, or in case
Distributor reasonably does not approve of counsel chosen by the Group, the
Group will reimburse Distributor, its shareholders, directors and employees, or
the controlling person or persons named as defendant or defendants in such suit,
for the fees and expenses of any counsel retained by Distributor or them. The
Group's indemnification agreement contained in this paragraph 1.11 and the
Group's representations and warranties in this agreement shall remain operative
and in full force and effect regardless of any investigation made by or on
behalf of Distributor, its shareholders, directors and employees, or any
controlling person, and shall survive the delivery of any Shares. This agreement
of indemnity will inure exclusively to


                                       -4-
<PAGE>   6
Distributor's benefit, to the benefit of its several shareholders, directors and
employees, and their respective estates, and to the benefit of the controlling
persons and their successors. The Group agrees promptly to notify Distributor of
the commencement of any litigation or proceedings against the Group or any of
its officers or Trustees in connection with the issue and sale of any Shares.

         1.12 Distributor agrees to indemnify, defend and hold the Group, its
several officers and Trustees and any person who controls the Group within the
meaning of Section 15 of the 1933 Act free and harmless from and against any and
all claims, demands, liabilities and expenses (including the costs of
investigating or defending such claims, demands or liabilities and any counsel
fees incurred in connection therewith) which the Group, its officers or Trustees
or any such controlling person, may incur under the 1933 Act or under common law
or otherwise, but only to the extent that such liability or expense incurred by
the Group, its officers or Trustees or such controlling person resulting from
such claims or demands, shall arise out of or be based upon any untrue, or
alleged untrue, statement of a material fact contained in information furnished
by Distributor to the Group and used in the answers to any of the items of the
registration statement or in the corresponding statements made in the
prospectus, or shall arise out of or be based upon any omission, or alleged
omission, to state a material fact in connection with such information furnished
by Distributor to the Group required to be stated in such answers or necessary
to make such information not misleading. Distributor's agreement to indemnify
the Group, its officers and Trustees, and any such controlling person, as
aforesaid, is expressly conditioned upon Distributor's being notified of any
action brought against the Group, its officers or Trustees, or any such
controlling person, such notification to be given by letter or telegram
addressed to Distributor at its principal office in Columbus, Ohio, and sent to
Distributor by the person against whom such action is brought, within 10 days
after the summons or other first legal process shall have been served.
Distributor shall have the right of first control of the defense of such action,
with counsel of its own choosing, satisfactory to the Group, if such action is
based solely upon such alleged misstatement or omission on Distributor's part,
and in any other event the Group, its officers or Trustees or such controlling
person shall each have the right to participate in the defense or preparation of
the defense of any such action. The failure to so notify Distributor of any such
action shall not relieve Distributor from any liability which Distributor may
have to the Group, its officers or Trustees, or to such controlling person by
reason of any such untrue or alleged untrue statement, or omission or alleged
omission, otherwise than on account of Distributor's indemnity agreement
contained in this paragraph 1.12.

         1.13 No Shares shall be offered by either Distributor or the Group
under any of the provisions of this agreement and no orders for the purchase or
sale of Shares hereunder shall be accepted by


                                       -5-
<PAGE>   7
the Group if and so long as the effectiveness of the registration statement then
in effect or any necessary amendments thereto shall be suspended under any of
the provisions of the 1933 Act or if and so long as a current prospectus as
required by Section 10(a) of the 1933 Act is not on file with the Commission;
provided, however, that nothing contained in this paragraph 1.13 shall in any
way restrict or have an application to or bearing upon the Group's obligation to
repurchase Shares from any Shareholder in accordance with the provisions of the
Group's prospectus, Declaration of Trust, or By-Laws.

         1.14 The Group agrees to advise Distributor as soon as reasonably
practical by a notice in writing delivered to Distributor:

              (a)  of any request by the Commission for amendments to the
         registration statement or prospectus then in effect or for additional
         information;

              (b)  in the event of the issuance by the Commission of any stop
         order suspending the effectiveness of the registration statement or
         prospectus then in effect or the initiation by service of process on
         the Group of any proceeding for that purpose;

              (c)  of the happening of any event that makes untrue any statement
         of a material fact made in the registration statement or prospectus
         then in effect or which requires the making of a change in such
         registration statement or prospectus in order to make the statements
         therein not misleading; and

              (d)  of all action of the Commission with respect to any amendment
         to any registration statement or prospectus which may from time to time
         be filed with the Commission.

         For purposes of this section, informal requests by or acts of the Staff
of the Commission shall not be deemed actions of or requests by the Commission.

         1.15 Distributor agrees on behalf of itself and its directors,
officers, agents, and employees to treat confidentially and as proprietary
information of the Group all records and other information relative to the Group
and its prior, present or potential Shareholders, and not to use such records
and information for any purpose other than performance of its responsibilities
and duties hereunder, except after prior notification to and approval in writing
by the Group, which approval shall not be unreasonably withheld and may not be
withheld where Distributor may be exposed to civil or criminal contempt
proceedings for failure to comply, when requested to divulge such information by
duly constituted authorities, or when so requested by the Group.

         1.16 This Agreement shall be governed by the laws of the State of Ohio.

         2.   Fee.

         The Distributor shall receive from the Funds identified on Schedule B
hereto with respect to such Funds' Investor A Shares a distribution fee at the

and Shareholder Service Plan attached as Schedule C hereto, and as amended from
time to time. The distribution fee described above shall be accrued daily and
shall be paid on the first business day of each month, or at such time(s) as
Distributor shall reasonably request.

         3.   Sale and Payment.

         Under this Agreement, the following provisions shall apply only with
respect to the sale of and payment of Shares of any class sold at an offering
price which includes a sales load (collectively, "Load Shares") as described in
the prospectuses of any Funds identified on Schedule D hereto (collectively, the
"Load Funds" and individually, a "Load Fund"):

              (a) Distributor shall have the right, as principal, to purchase
         Load Shares from the Load Funds at their net asset value and to sell
         such Load Shares to the public against orders therefor at the
         applicable public offering price, as defined in Section 4 hereof.
         Distributor shall also have the right, as principal, to sell Load
         Shares to dealers against orders therefor at the public offering price
         less a concession determined by Distributor, which concession shall not
         exceed the amount of the sales charge or underwriting discount, if any,
         referred to in Section 4 below.

              (b) Prior to the time of delivery of any Load Shares by a Load
         Fund to, or on the order of, Distributor, Distributor shall pay or
         cause to be paid to the Load Fund or to its order an amount in federal
         funds equal to the applicable net asset value of such Load Shares.
         Distributor may retain so much of any sales charge or underwriting
         discount as is not allowed by Distributor as a concession to dealers.

         4.   Public Offering Price.

         The public offering price shall be the net asset value of Load Shares,
plus any applicable sales charge, all as set forth in the current prospectus of
the Load Fund. The net asset value of Load Shares shall be determined in
accordance with the provisions of the Declaration of Trust and By-Laws of the
Group and the then current prospectus of the Load Fund.

              INVESTOR A DISTRIBUTION AND SHAREHOLDER SERVICE PLAN

         This Plan (the "Investor A Plan") constitutes a distribution and
shareholder service plan of The Cardinal Group, an Ohio business trust (the

to broker/dealers, banks and other institutions (a "Participating Organization")
for distribution assistance and/or Shareholder service pursuant to an agreement
with the Participating Organization or for distribution assistance and/or
Shareholder service provided by the Distributor pursuant to an agreement between
the Distributor and the Group; or (b) reimbursement of expenses incurred by a

distribution assistance and/or Shareholder service including, but not limited
to, the reimbursement of expenses relating to printing and distributing
prospectuses to persons other than Shareholders of an Investor A Plan Fund,
printing and distributing advertising and sales literature and reports to
Shareholders used in connection with the sale of Investor A Shares, and
personnel and communication equipment used in servicing Shareholder accounts and
prospective shareholder inquiries. For purposes of the Investor A Plan, a
Participating Organization may include the Distributor or any of its affiliates
or subsidiaries.

         Section 2. The Investor A Plan Fee shall be paid by the Investor A Plan
Funds to the Distributor only to compensate or to reimburse the Distributor for
payments or expenses incurred pursuant to Section 1.

         Section 3. The Investor A Plan shall not take effect until it has been
approved, together with any related agreements, by votes of the majority (or
whatever greater percentage may, from time to time, be required by Section 12(b)
of the 1940 Act or the rules and regulations thereunder) of both (a) the
Trustees of the Group, and (b) the Independent Trustees of the Group cast in
person at a meeting called for the purpose of voting on the Investor A Plan or
such agreement.

         Section 4. The Investor A Plan shall continue in effect for a period of
more than one year after it takes effect only so long as such continuance is
specifically approved at least annually in the manner provided for approval of
the Investor A Plan in Section 3.

         Section 5. Any person authorized to direct the disposition of monies
paid or payable by the Investor A Plan Funds pursuant to the Investor A Plan or
any related agreement shall provide to the Trustees of the Group, and the
Trustees shall review, at least quarterly, a written report of the amounts so
expended and the purposes for which such expenditures were made.

         Section 6. The Investor A Plan may be terminated at any time by vote of
a majority of the Independent Trustees, or by vote of a majority of the
outstanding Investor A Shares of an Investor A Plan Fund.

         Section 7. All agreements with any person relating to implementation of
the Investor A Plan shall be in writing, and any agreement related to the
Investor A Plan shall provide:

              (a) That such agreement may be terminated at any time, without
         payment of any penalty, by vote of a majority of the Independent
         Trustees or by vote of a majority of the outstanding Investor A Shares
         of the Investor A Plan Fund, on not more than 60 days' written notice
         to any other party to the agreement; and

              (b) That such agreement shall terminate automatically in the event
         of its assignment.

materially the amount of distribution expenses of an Investor A Plan Fund
permitted pursuant to Section 1 hereof without approval by a vote of at least a
majority of the outstanding Investor A Shares of such Investor A Plan Fund, and
all material amendments to the Investor A Plan shall be approved in the manner
provided for approval of the Investor A Plan in Section 3.

         Section 9. As used in the Investor A Plan, (a) the term "Independent
Trustees" shall mean those Trustees of the Group who are not interested persons
of the Group, and have no direct or


                                       C-2

indirect financial interest in the operation of the Investor A Plan or any
agreements related to it, and (b) the terms "assignment", "interested person"

                          Administrative Services Plan

         Section 1. Upon the recommendation of Cardinal Management Corp.
("CMC"), in its capacity as investment adviser and manager of The Cardinal Group
(the "Group"), any officer of the Group is authorized to execute and deliver, in
the name and on behalf of the Group, written agreements in substantially the
form attached hereto as Appendix A or in any other form duly approved by the
Board of Trustees ("Servicing Agreements") with financial institutions which are
shareholders of record or which have a servicing relationship ("Service
Organizations") with the beneficial owners of Investor Y shares of the Group
("Shares") of one or more of the Group's series or portfolios (such series or
portfolios hereinafter individually called a "Series" and collectively the
"Series"). Such Servicing Agreements shall require the Service Organizations to
provide administrative support services as set forth therein and as described in
the Group's applicable Prospectuses to their customers who own of record or
beneficially Shares in consideration for a fee, computed daily and paid monthly
in the manner set forth in the Servicing Agreements, at the annual rate of up to
 .15% of the average daily net asset value of Shares owned of record or
beneficially by such customers. Any bank, trust company, thrift institution,
broker-dealer or other financial institution, including The Ohio Company, is
eligible to become a Service Organization and to receive fees under this Plan.
All expenses incurred by the Group with respect to Shares of a particular Series
in connection with the Servicing Agreements and the implementation of this Plan
shall be borne entirely by the holders of Shares of the Series.

         Section 2. So long as this Plan is in effect, CMC shall provide to the
Group's Board of Trustees, and the Trustees shall review, at least quarterly, a
written report of the amounts expended pursuant to this Plan and the purposes
for which such expenditures were made.

         Section 3. The Plan shall not take effect with respect to the Shares of
a Series until it has been approved, together with the form of the Servicing
Agreements, by a vote of a majority of the Trustees who are not "interested
persons" of the Group (as defined in the Investment Company Act of 1940) and who
have no direct or indirect financial interest in the operation of this Plan or
in any agreements related to this Plan (the "Disinterested Trustees"), cast in
person at a meeting called for the purpose of voting on the
<PAGE>   3
Plan or such Servicing Agreement, provided, however that the Plan shall not be
implemented for a particular Series prior to the effective date of the
post-effective amendment to the Group's registration statement describing the
Plan and its implementation with respect to that Series.

         Section 4. Unless sooner terminated, this Plan shall continue until
January 2, 1998, and thereafter, shall continue automatically for successive
annual periods provided such continuance is approved at least annually by a
majority of the Board of Trustees, including a majority of the Disinterested
Trustees.

         Section 5. This Plan may be amended at any time with respect to any
Series by the Board of Trustees, provided that any material amendments of the
terms of this Plan shall become effective only upon the approvals set forth in
Section 4.

         Section 6. This Plan is terminable at any time with respect to any
Series by vote of a majority of the Disinterested Trustees.

         Section 7. While this Plan is in effect, the selection and nomination
of those Disinterested Trustees shall be committed to the discretion of the
Group's Disinterested Trustees.

         Section 8. This Plan has been adopted as of July 19, 1996 and intended
to be effective on or about January 2, 1997.

         Section 9. The Cardinal Group is a business trust organized under
Chapter 1746, Ohio Revised Code, and under a Declaration of Trust, to which
reference is hereby made and a copy of which is on file at the office of the
Secretary of State of Ohio as required by law, and to any and all amendments
thereto so filed or hereafter filed. The obligations of "The Cardinal Group"
entered into in the name or on behalf thereof by any of the Trustees, officers,
employees or agents are made not individually, but in such capacities, and are
not binding upon any of the Trustees, officers, employees, agents or shareholder
of the Group personally, but bind only the assets of the Group, as set forth in
Section 1746.13(A), Ohio Revised Code, and all persons dealing with any of the
Series of the Group must look solely to the assets of the Group belonging to
such Series for the enforcement of any claims against the Group.

of such Fund (the "Investor A Plan Fee") for: (a) payments the Distributor makes
to broker/dealers, banks and other institutions (a "Participating Organization")
for distribution assistance and/or Shareholder service pursuant to an agreement
with the Participating Organization or for distribution assistance and/or
Shareholder service provided by the Distributor pursuant to an agreement between
the Distributor and the Group; or (b) reimbursement of expenses incurred by a

prospective shareholder inquiries. For purposes of the Investor A Plan, a
Participating Organization may include the Distributor or any of its affiliates
or subsidiaries.

         Section 2. The Investor A Plan Fee shall be paid by the Investor A Plan
Funds to the Distributor only to compensate or to reimburse the Distributor for
payments or expenses incurred pursuant to Section 1.

         Section 3. The Investor A Plan shall not take effect until it has been
approved, together with any related agreements, by votes of the majority (or

of the 1940 Act or the rules and regulations thereunder) of both (a) the
Trustees of the Group, and (b) the Independent Trustees of the Group cast in

such agreement.

         Section 4. The Investor A Plan shall continue in effect for a period of

specifically approved at least annually in the manner provided for approval of
the Investor A Plan in Section 3.

         Section 5. Any person authorized to direct the disposition of monies
paid or payable by the Investor A Plan Funds pursuant to the Investor A Plan or
any related agreement shall provide to the Trustees of the Group, and the
Trustees shall review, at least quarterly, a written report of the amounts so
expended and the purposes for which such expenditures were made.

         Section 6. The Investor A Plan may be terminated at any time by vote of
a majority of the Independent Trustees, or by vote of a majority of the
outstanding Investor A Shares of an Investor A Plan Fund.

         Section 7. All agreements with any person relating to implementation of
the Investor A Plan shall be in writing, and any agreement related to the
Investor A Plan shall provide:

              (a) That such agreement may be terminated at any time, without
         payment of any penalty, by vote of a majority of the Independent
         Trustees or by vote of a majority of the outstanding Investor A Shares
         of the Investor A Plan Fund, on not more than 60 days' written notice
         to any other party to the agreement; and

              (b) That such agreement shall terminate automatically in the event
         of its assignment.

         Section 8. The Investor A Plan may not be amended to increase
materially the amount of distribution expenses of an Investor A Plan Fund

majority of the outstanding Investor A Shares of such Investor A Plan Fund, and
all material amendments to the Investor A Plan shall be approved in the manner
provided for approval of the Investor A Plan in Section 3.

         4. The Group and the Company each acknowledge that either party may
enter into similar agreements with others without the consent of the other
party.

         5. The Company shall prepare such quarterly reports for the Group as

Group.

         7. This Agreement is a related agreement under the Group's Investor A
Distribution and Shareholder Service Plan (the "Plan").

direct or indirect financial interest in the operation of the Plan or in any
related agreements to the Plan ("Disinterested Trustees") or by a majority of
the outstanding voting securities of the Group on not more than sixty (60) days
written notice to the parties to this Agreement.

                                 RULE 18f-3 PLAN


         WHEREAS, The Cardinal Group, an Ohio business trust (the "Group"), is
an open-end management investment company registered under the Investment
Company Act of 1940 (the "1940 Act");

         WHEREAS, Cardinal Management Corp., an Ohio corporation ("CMC"), serves
as investment adviser and The Ohio Company, an Ohio corporation ("TOC"), serves
as principal underwriter for the Group;

         WHEREAS, The Group has adopted a Distribution and Shareholder Service
Plan ("12b-1 Plan") under Rule 12b-1 of the 1940 Act providing for, in the case
of Investor A shares, a service fee at an annual rate of up to .25% per annum of
average net assets, and expects to adopt additional plans under Rule 12b-1
("Additional 12b-1 Plans"), providing for, in the case of Investor B shares and
Investor C shares, fees of not more than 1% per annum of average net assets,
comprised of a distribution fee in an amount not to exceed .75% per annum of
average net assets and a service fee not to exceed .25% per annum of average net
assets;

         WHEREAS, The Group has adopted an Administrative Services Plan
providing for, in the case of Investor Y shares, an administrative services fee
at an annual rate of up to .15% per annum of average net assets;

         WHEREAS, The Group has established a Multiple Class Distribution System
enabling the Group, as described in its prospectus or prospectuses, to offer
investors the option of purchasing shares of its non-money market fund series
(a) with a front-end sales load (which can vary among series and which is
subject to certain reductions and waivers among groups of purchasers) and a
12b-1 plan providing for a service fee (the "Front-End Load Option" or "Investor
A shares"), (b) without a front-end sales load, but subject to a contingent
deferred sales charge ("CDSC") (which can vary among series) and a 12b-1 plan
providing for a distribution fee and a service fee (the "Deferred Option" or
"Investor B shares"), (c) without a front-end sales load, but subject to CDSC,
applicable over a shorter time period


                                       -1-
<PAGE>   2
than the CDSC applicable to Investor B shares, and a 12b-1 plan providing for a
distribution fee and a service fee (the "Level Load Option" or "Investor C
shares") and (d) for certain qualifying institutional purchasers, without a
front-end sales load, CDSC or distribution/service fee but subject to an
administrative services fee (the "Institutional Class" or "Investor Y shares");
and

         WHEREAS, Rule 18f-3 under the 1940 Act permits an open-end management
investment company to issue multiple classes of voting stock representing
interests in the same portfolio notwithstanding Sections 18(f)(1) and 18(i)
under the 1940 Act if, among other things, such investment company adopts a
written plan setting forth the separate arrangement and expense allocation of
each class and any related conversion features or exchange privileges;

         NOW, THEREFORE, the Group, wishing to be governed by Rule 18f- 3 under
the 1940 Act, hereby adopts this Rule 18f-3 Plan as follows:

         1. Each class of shares of a non-money market fund series will
represent interests in the same portfolio of investments of such series of the
Group, and be identical in all respects to each other class of that series,
except as set forth below. The only differences among the various classes of
shares of the non-money market fund series of the Group will relate solely to
(a) different distribution or service fee payments associated with any Rule
12b-1 plan for a particular class of shares and any other costs relating to
implementing or amending such plan (including obtaining shareholder approval of
such plan or any amendment thereto), which will be borne solely by shareholders
of such classes; (b) different administrative services fees; (c) different Class
Expenses, which will be limited to the following expenses determined by the
Trustees to be attributable to a specific class of shares: (i) transfer agency
fees identified as being attributable to a specific class; (ii) printing and
postage expenses related to preparing and distributing materials such as
shareholder reports, prospectuses,and proxy statements to current shareholders
of a specific class; (iii) Blue Sky registration fees incurred by a class of
shares; (iv) SEC registration fees incurred by a class; (v) expenses of
administrative personnel and services as required to support the shareholders of
a specific class; (vi) litigation or other legal expenses and audit or other
accounting expenses relating solely to one class; (vii) Trustees' fees or
expenses incurred as a result of issues relating to one class; and (viii)
shareholder meeting costs that relate to a specific class; (d) the voting rights
related to any 12b-1 Plan affecting a specific class of shares; (e) conversion
features; (f) exchange privileges; and (g) class names or designations. Any
additional incremental expenses not specifically identified above that are
subsequently identified and determined to be properly applied to one class of


                                       -2-
<PAGE>   3
shares of a series of the Group shall be so applied upon approval by a majority
of the Trustees of the Group, including a majority of the Trustees who are not
interested persons of the Group.

         2. Under the Multiple Class Distribution System, certain expenses may
be attributable to the Group, but not to a particular series or class thereof.
All such expenses will be allocated among series based upon the relative
aggregate net assets of such series. Expenses that are attributable to a
particular series, but not to a particular class thereof, will be borne by each
class of such series on the basis of the relative aggregate net assets of the
classes. Notwithstanding the foregoing, the principal underwriter, the
investment adviser or other provider of services to the Group may waive or
reimburse the expenses of a specific class or classes to the extent permitted
under Rule 18f-3 under the 1940 Act and pursuant to any applicable ruling,
procedure or regulation of the Internal Revenue Service.

         A class of shares may be permitted to bear expenses that are directly
attributable to such class including: (a) any distribution/service fees
associated with any Rule 12b-1 plan for a particular class and any other costs
relating to implementing or amending such Plan (including obtaining shareholder
approval of such plan or any amendment thereto); (b) any administrative services
fees attributable to such class; and (c) any Class Expenses determined by the
Trustees to be attributable to such class.

         3. After a shareholder's Investor B shares of a series have been
outstanding for six years, they will automatically convert to Investor A shares
of the same series at the relative net asset values of the two classes;
provided, however, that Investor B shares issued upon reinvestment of income and
capital gain dividends and other distributions will be converted to Investor A
shares on a pro rata basis with the Investor B shares.

         4. At such time as Investor Y shares are held by a person or entity not
qualified to purchase or hold Investor Y shares such Investor Y shares
automatically shall convert to Investor A shares at the relative net asset
values of the two classes.

         5. Any conversion of shares of one class to shares of another class is
subject to the continuing availability of a ruling of the Internal Revenue
Service or an opinion of counsel to the effect that the conversion of shares
does not constitute a taxable event under federal income tax law. Any such
conversion may be suspended if such a ruling or opinion is no longer available.

         6. To the extent exchanges are permitted, shares of any class of the
Group will be exchangeable with shares of the same



                                       -3-
<PAGE>   4
class of another series of the Group, or with money market fund shares of the
Group as described in the applicable prospectus. Exchanges will comply with all
applicable provisions of Rule 11a-3 under the 1940 Act. For purposes of
calculating the time period remaining on the conversion of Investor B shares to
Investor A shares, Investor B shares received on exchange retain their original
purchase date.

         7. Dividends paid by a series of the Group as to each class of its
shares, to the extent any dividends are paid, will be calculated in the same
manner, at the same time, on the same day, and will be in the same amount,
except that any distribution/service fees, administrative services fees, and
Class Expenses allocated to a class will be borne exclusively by that class.

         8. Any distribution arrangement of the Group,including distribution
fees and front-end and deferred sales loads, will comply with Section 2830 of
the Conduct Rules of the National Association of Securities Dealers, Inc.

         9. All material amendments to this Plan must be approved by a majority
of the members of the Group's Trustees, including a majority of the Board
members who are not interested persons of the Group.
