                                CARDINAL FUNDS

                                                                January 26, 1996
    
 
Dear The Cardinal Fund Inc. Shareholder:
 
   
The Board of Directors of The Cardinal Fund Inc. ("TCFI") recently reviewed and
unanimously approved a proposal to reorganize TCFI with and into a newly created
series of The Cardinal Group (the "Group"). This Agreement and Plan of
Reorganization and Liquidation is described in the accompanying Combined
Prospectus/Proxy Statement and will be addressed at a Special Meeting of
Shareholders on March 15, 1996.
    
 
The primary purpose of the proposed reorganization is to achieve certain
economies of scale by having TCFI become an additional series of the Group
rather than operate as a separate stand-alone investment company. By operating
more efficiently, we expect to realize cost savings through the elimination of
certain Annual Meeting expenses, a reduction of printing and mailing
expenditures, the lowering of regulatory filing expenses and the reduction of
professional fees. The Board determined that such a reorganization is in the
best interest of TCFI.
 
   
If the proposed reorganization is approved, you will receive shares of the newly
created series of the Group, known as The Cardinal Fund, in exchange for your
shares of TCFI. Shares received in this distribution will be equal in value at
the time of reorganization to your shares in TCFI. There will be no adverse
federal income tax consequences associated with this distribution.
 
As a result of the reorganization, many features of the new series will be the
same as those of TCFI. For instance, the securities in the underlying portfolio
will remain the same. Purchase and redemption procedures will not change. Slight
differences in investment objectives, policies and restrictions are proposed but
are not expected to increase significantly the level of risk associated with
your investment.
 
There are, however, two important changes that I wish to draw to your attention.
First, Cardinal Management Corp. will become the investment adviser instead of
its parent company, The Ohio Company. Second, operating expenses for the new
series' shares are expected to be higher than those of TCFI. This is due to the
addition of a Rule 12b-1 Plan and higher investment advisory and fund accounting
fees. This increase will enable us to be more competitive in today's mutual fund
marketplace by investing in the people and resources necessary to deliver a high
level of service. Although operating expenses will be greater, the proposed
level places your investment company within the norms of its industry peer
group.
 
Please read the accompanying materials carefully. For more details regarding the
proposed reorganization, direct any questions you may have to the Treasurer of
TCFI, Mr. James Schrack, at (800) 282-9446. IT IS VERY IMPORTANT THAT YOU
COMPLETE AND RETURN THE PROXY CARD AS SOON AS POSSIBLE.
    
 
Thank you for your support and investment in The Cardinal Fund Inc.
 
   
                                          Sincerely,
    
 
   
                                          FRANK W. SIEGEL, CFA
    
                                          President
                                          The Cardinal Fund Inc.
 
   
P.S. YOUR VOTE IS VERY IMPORTANT TO US. PLEASE COMPLETE, SIGN, DATE AND RETURN
THE PROXY CARD IN THE ENCLOSED POSTAGE-PAID ENVELOPE.

     exchange for shares of the Acquiring Fund, and the assumption by the
     Acquiring Fund of all of the liabilities of TCFI; and (b) the distribution
     to shareholders of TCFI of shares of the Acquiring Fund so received in
     complete liquidation of TCFI;

     ending September 30, 1996; and
 
     6. To transact such other business as may properly come before the Meeting,
     or any adjournment(s) thereof, including any adjournment(s) necessary to
     obtain requisite quorums and/or approvals.

This Combined Prospectus/Proxy Statement is being furnished to shareholders of
The Cardinal Fund Inc., an Ohio corporation ("TCFI"), in connection with the
solicitation of proxies by the Board of Directors of TCFI to be used at a
Special Meeting of Shareholders of TCFI (the "Meeting"), to be held at The
Athletic Club of Columbus, 136 East Broad Street, Columbus, Ohio 43215, on
Friday, March 15, 1996, beginning at 9:30 A.M. (Eastern Time).
    
 
In addition to the customary annual election of Directors and ratification of
the selection of independent accountants, the Directors of TCFI are seeking your
approval of an Agreement and Plan of Reorganization and Liquidation (the "Plan")
and of a related amendment to TCFI's fundamental investment policies. The Plan
contemplates that The Cardinal Fund (the "Acquiring Fund"), a series or
portfolio of The Cardinal Group (the "Group"), will acquire all of the assets of
and will assume all of the liabilities of TCFI in exchange for shares of the
Acquiring Fund.
 
Following such exchange, the shares of the Acquiring Fund received by TCFI will
be distributed to TCFI's shareholders and TCFI will be liquidated and dissolved.
This exchange and distribution transaction is sometimes referred to herein as
the "Reorganization."
 
This Combined Prospectus/Proxy Statement, which should be retained for future
reference, sets forth concisely the information about the Acquiring Fund that a
prospective investor, including shareholders of TCFI, should know before
investing. Additional information about the Reorganization and the Acquiring
Fund is contained in a separate Statement of Additional Information which has
been filed with the Securities and Exchange Commission (the "Commission") and is
available upon request without charge by calling the Group at (800) 282-9446 or
writing to the Group at the address set forth above. The Statement of Additional
Information bears the same date as this Combined Prospectus/Proxy Statement and
is incorporated by reference herein.
 
THE SHARES OF THE ACQUIRING 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 ACQUIRING FUND
INVOLVES CERTAIN INVESTMENT RISKS, INCLUDING THE POSSIBLE LOSS OF PRINCIPAL.
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
   EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
     SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
       PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY
         REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
 
Upon completion of the Reorganization, you will receive full and fractional
shares of the Acquiring Fund equal in value when issued to the shares of TCFI
owned by you immediately prior to the Reorganization. No commissions or sales
loads will be charged in connection with the Reorganization and there will be no
adverse federal income tax consequences. You should separately consider any
other tax consequences in consultation with your tax advisers.
   
 
As discussed in detail herein, the investment objectives and strategy of the
Acquiring Fund are substantially similar to those of TCFI. There are some
differences between investment objectives, policies and restrictions, as well as
differences in fee levels and in voting rights, which are described in detail
below. The Prospectus of the Acquiring Fund relating to its shares, dated
January 10, 1996, is incorporated by reference in this Combined Prospectus/Proxy
Statement and accompanies this Combined Prospectus/Proxy Statement.
 
TCFI's Prospectus dated January 19, 1996, contains additional information about
TCFI, has been filed with the Commission, is incorporated by reference herein
and is available without charge by writing TCFI at 155 East Broad Street,
Columbus, Ohio 43215, or by calling TCFI at (800) 282-9446. Copies of documents
requested will be sent by first-class mail to the requesting shareholder within
one business day of the request.

                                    GENERAL
 
   
This Combined Prospectus/Proxy Statement is furnished in connection with the
solicitation of proxies by the Board of Directors of TCFI to be used in
connection with the Meeting to be held on Friday, March 15, 1996.
    
 
The management knows of no business which will be presented for consideration
other than that mentioned in Issues 1, 2, 3, 4 and 5 of the Notice of Special
Meeting of Shareholders. If any other matters are properly presented at the
Meeting or any adjournment(s) thereof, it is the intention of the persons named
therein to vote the proxies in accordance with their judgment on such matters.
 
   
The Board of Directors has fixed the close of business on January 22, 1996, as
the record date for the determination of shareholders entitled to notice of and
to vote at the Meeting (the "Record Date"). On the Record Date there were
17,841,144 shares of common stock, without par value ("Shares"), of TCFI
outstanding and entitled to vote. Each of the Shares is entitled to one vote.
Shareholders of fractional Shares will be entitled to a vote of such fraction.
Shareholders present in person or by proxy at the Meeting will be deemed to
constitute a quorum for the transaction of business at the Meeting.
    
 
The expenses for preparation, printing and mailing of the enclosed proxy,
accompanying notice and Combined Prospectus/Proxy Statement, or any
re-solicitation of the foregoing, will be paid in part by TCFI and in part by
The Ohio Company.
 
Only shareholders of record at the close of business on the Record Date will be
entitled to notice of and to vote at the Meeting. Shares represented by
management proxies, unless previously revoked, will be voted at the Meeting in
accordance with the instructions of the shareholders. If no instructions are
given, the proxies will be voted in favor of the proposals. To revoke a
management proxy, the shareholder giving such proxy must either submit to TCFI a
subsequently dated proxy, deliver to TCFI a written notice of revocation or
otherwise give notice of revocation in open meeting, in all cases prior to the
exercise of the authority granted in the management proxy.
 
In the event that sufficient votes are not received by the Meeting date, a
person named as proxy may propose one or more adjournments of the Meeting for a
period or periods of not more than 45 days in the aggregate to permit further
solicitation of proxies. Any such adjournment will require the affirmative vote
of the holders of a majority of TCFI's shares present at the Meeting in person
or by proxy. The persons named as proxies will vote in favor of such adjournment
those proxies which they are entitled to vote in favor of the proposals and will
vote against any such adjournment those proxies required to be voted against the
proposals.
 
Each shareholder may vote cumulatively for the election of directors if notice
of a desire to do so is given in writing by any shareholder to the President,
Vice President or Secretary of TCFI not less than forty-eight (48) hours before
the time fixed for the Meeting and if announcement of the giving of such notice
is made upon the convening of the Meeting by the Chairman or Secretary or by or
on behalf of the shareholder giving such notice. In the event voting shall be
cumulative, each shareholder has the right to cumulate such voting power as he
possesses and to give one candidate as many votes as the number of directors to
be elected multiplied by the number of Shares held, or to distribute his votes
on the same principle among two or more candidates, as he sees fit.
 
   
The mailing address of the principal executive offices of TCFI is 155 East Broad
Street, Columbus, Ohio 43215. The approximate date on which this Combined
Prospectus/Proxy Statement and form of proxy are first sent to shareholders is
on or about January 31, 1996.
    
 
   
As of the Record Date, the Acquiring Fund had no shares outstanding. The
Acquiring Fund does not have and will not have immediately prior to the
effective date of the Reorganization, any assets or liabilities nor will it have
commenced operations.
    
 
Any proxy which is properly executed and received in time to be voted at the
Meeting will be counted in determining whether a quorum is present and will be
voted in accordance with the instructions marked thereon. Abstentions and
"broker non-votes" (i.e., proxies from brokers or
 
                                        1
<PAGE>   8
 
nominees indicating that such persons have not received instructions from the
beneficial owners or other persons entitled to vote shares as to a particular
matter with respect to which the brokers or nominees do not have discretionary
power to vote) will be counted for purposes of determining whether a quorum is
present. For purposes of determining whether a proposal has been approved,
abstentions and broker non-votes will have the effect of a vote against the
proposal in those instances where approval of an issue requires a certain
percentage of all votes outstanding or of the votes constituting the quorum, but
will have no effect where approval of the issue requires a plurality of the
votes being voted.
 
   
                        APPROVAL OF THE PLAN -- ISSUE 1
 
SUMMARY
 
This Summary is qualified in its entirety by reference to the additional
information contained elsewhere in this Prospectus/Proxy Statement, the Plan, a
copy of which is attached to this Prospectus/Proxy Statement as Exhibit A, the
accompanying Prospectus of the Acquiring Fund dated January 10, 1996, and the
Prospectus of TCFI dated January 19, 1996.
 
PROPOSED REORGANIZATION.  The Plan provides for the transfer of all of the
assets of TCFI to the Acquiring Fund in exchange for shares of the Acquiring
Fund and the assumption by the Group on behalf of the Acquiring Fund of all of
the liabilities of TCFI. The Plan also calls for the distribution of shares of
the Acquiring Fund to TCFI's shareholders in complete liquidation of TCFI. (The
foregoing proposed transactions are referred to in this Prospectus/Proxy
Statement as the "Reorganization.") As a result of the Reorganization, each
shareholder of TCFI will become the owner of that number of full and fractional
shares of the Acquiring Fund having an aggregate value equal to the aggregate
value of the shareholder's Shares of TCFI as of the close of business on the day
preceding the date that TCFI's assets are exchanged for shares of the Acquiring
Fund. Proposals for similar reorganizations with and into other series of the
Group are simultaneously being made to shareholders of Cardinal Government
Obligations Fund, Cardinal Government Securities Trust and Cardinal Tax Exempt
Money Trust, the other funds of the Cardinal family of funds.
 
For the reasons set forth below under "THE PROPOSED TRANSACTION -- REASONS FOR
THE REORGANIZATION," the Board of Directors of TCFI, including directors of TCFI
(the "Independent Directors") who are not "interested persons" as that term is
defined in the Investment Company Act of 1940, as amended (the "1940 Act"), at a
special meeting held on November 13, 1995, unanimously concluded that the
Reorganization will be in the best interests of TCFI and its shareholders and
that the interests of TCFI's existing shareholders will not be diluted as a
result of the transaction contemplated by the Reorganization and therefore has
submitted the Plan for approval by TCFI's shareholders. The Board of Trustees of
the Group has reached similar conclusions with respect to the Acquiring Fund and
has also approved the Reorganization in respect of the Acquiring Fund.
    
 
Approval of the Reorganization will require the affirmative vote of the holders
of Shares entitling them to exercise a majority of the voting power of TCFI. See
"APPROVAL AND CONSUMMATION OF THE PROPOSED TRANSACTION" below.
 
COMPARATIVE EXPENSE INFORMATION.  The purpose of the following tables is to
assist shareholders of TCFI in understanding the costs and expenses that a
shareholder in the Acquiring Fund would bear directly or indirectly. The
shareholder transaction expenses for the Acquiring Fund are estimated for the
fiscal period following the Reorganization and ending September 30, 1996, and
reflect the proposed Rule 12b-1 fee waiver. The expenses of TCFI are based upon
the fiscal year ended September 30, 1995.

(1)The investment advisory fee charged to the Acquiring Fund is 10 basis points
   higher than that currently charged to TCFI. In addition, the Acquiring Fund,
   unlike TCFI, is subject to a Rule 12b-1 fee. However, The Ohio Company has
   agreed with the Group to waive all of its Rule 12b-1 fees for the period
   following the effective date of the Reorganization and ending September 30,
   1996. Absent such fee waiver, 12b-1 Fees and Total Fund Operating Expenses
   for the Acquiring Fund are estimated to be 0.25% and 1.06%, respectively.

(2) "Other Expenses" are based upon estimated amounts for the current fiscal
    year. In addition, the Acquiring Fund pays a fund accounting fee to Cardinal
    Management Corp. ("CMC"), a wholly owned subsidiary of The Ohio Company, in
    the amount of .03% of the first $100 million of average daily net assets and
    .01% of its average daily net assets in excess of $100 million. TCFI pays no
    such fee.

    after giving effect to the Reorganization.

FEDERAL INCOME TAX CONSEQUENCES.  Prior to completion of the Reorganization,
TCFI will have received an opinion of counsel that, upon the consummation of the
Reorganization, no gain or loss will be recognized by TCFI or its shareholders
for federal income tax purposes. The holding period and aggregate tax basis for
the Acquiring Fund shares that are received by a TCFI shareholder will be the
same as the holding period and aggregate tax basis of the Shares of TCFI
previously held by such shareholder. In addition, the holding period and tax
basis of the assets of TCFI in the hands of the Acquiring Fund as a result of
the Reorganization will be the same as the holding period and tax basis of the
assets in the hands of TCFI immediately prior to the Reorganization.
    
 
APPROVAL AND CONSUMMATION OF THE PROPOSED TRANSACTION.  The Board of Directors
of TCFI, at a special meeting held on November 13, 1995, determined unanimously
that the Reorganization is in the best interests of TCFI and that the interests
of the existing shareholders of TCFI will not be diluted
 
                                        3
<PAGE>   10
 
   
as a result of the Reorganization. Similarly, the Board of Trustees of the Group
unanimously determined that the Reorganization is in the best interests of the
Group and the Acquiring Fund. The proposed Reorganization of TCFI with and into
the Acquiring Fund is part of a larger plan to reorganize each of TCFI, Cardinal
Tax Exempt Money Trust, Cardinal Government Securities Trust and Cardinal
Government Obligations Fund, each a separate stand-alone investment company,
with and into a separate portfolio of the Group, and will allow the shareholders
of TCFI to realize certain economies of scale as a result of becoming
shareholders of a series investment company and thus having certain fixed fees
spread over a larger pool of assets. In addition, the corporate structure of and
the more uniform investment policies and restrictions of the Acquiring Fund will
improve oversight of compliance obligations and overall management of the
shareholders' investment since many of such policies and restrictions will be
the same for all of the series or portfolios of the Group. The investment
advisory fee paid by the Acquiring Fund to CMC is ten basis points higher than
that fee charged to TCFI by The Ohio Company. However, CMC and The Ohio Company
have undertaken to use such higher fee to commit additional investment
management personnel and additional resources to manage the portfolio of the
Acquiring Fund. The Acquiring Fund is also subject to the Rule 12b-1 plan of the
Group and therefore pays a 25 basis point (0.25%) fee which TCFI does not pay.
The Boards of TCFI and the Group, in approving the Reorganization, concluded
that the payment of such Rule 12b-1 fees will improve the servicing of
shareholder accounts by broker-dealers and is necessary to compete successfully
through a broker-dealer distribution channel in today's marketplace when
competing funds pay a similar or higher fee to such brokers. As a result, the
Boards of TCFI and the Group found that the payment of such Rule 12b-1 fees will
promote fund sales and discourage fund redemptions and that a larger fund will
be able to spread its fixed costs over a wider base and to achieve better
portfolio diversification. Finally, the Boards of TCFI and the Group considered
the fund accounting fees charged by CMC to the Acquiring Fund (and which are not
charged to TCFI) and found them to be fair and reasonable and comparable to
those charged by other service providers. See "THE PROPOSED
TRANSACTION -- REASONS FOR THE PROPOSED TRANSACTION."
    
 
To be approved, the Plan will require the affirmative vote of the holders of
Shares entitling them to exercise a majority of the voting power of TCFI. The
Reorganization with respect to TCFI is not contingent on the approval of the
Reorganization with respect to any of the other Cardinal funds. If TCFI's
shareholders do not approve the proposed Reorganization, TCFI's Board of
Directors will consider what other alternatives would be in the shareholders'
best interests. If the Plan is approved at the Meeting, the effective date of
the Reorganization (the "Closing Date") is expected to be on or about March 31,
1996, subject, however, to the receipt by TCFI and the Group, if necessary, of
an order of exemption from the Commission with respect to the Reorganization.
 
INVESTMENT OBJECTIVES AND POLICIES.  TCFI and the Acquiring Fund have
substantially similar investment objectives, policies and restrictions. TCFI
seeks to achieve long-term growth of capital and income through selective
participation in the long-term progress of American businesses and industries.
Current income, while a factor in portfolio selection, is secondary to TCFI's
primary objective. The Acquiring Fund seeks to achieve long-term growth of
capital and income. Current income is a secondary objective. The Acquiring Fund
seeks to achieve its objectives through selective participation in the long-term
progress of businesses and industries. The policy of each of TCFI and the
Acquiring Fund is generally to invest in equity securities. For a discussion of
the differences between the investment restrictions of the Acquiring Fund and
TCFI, see "COMPARISON OF INVESTMENT OBJECTIVES, POLICIES AND
RESTRICTIONS -- INVESTMENT RESTRICTIONS."
 
FEES AND EXPENSES.  TCFI pays the following fees: to The Ohio Company, an
investment advisory and management fee computed daily and payable quarterly at
the annual rate of 0.50% of the value of its average daily net assets; to CMC
for transfer agency services an annual fee, paid monthly, at an annual rate of
$18 per shareholder account plus out-of-pocket expenses.
 
The Acquiring Fund pays the following fees to CMC: an investment advisory and
management fee computed daily and payable monthly at the annual rate of 0.60% of
the value of its average daily net assets; for transfer agency services an
annual fee, paid monthly, at an annual rate of $18 per
 
                                        4
<PAGE>   11
 
shareholder account plus out-of-pocket expenses; and for fund accounting
services a fee computed daily and paid periodically at an annual rate of .03% of
its average daily net assets of $100 million or less and .01% of its average
daily net assets in excess of $100 million.
 
   
Shares of each of TCFI and the Acquiring Fund are distributed by The Ohio
Company, a registered broker-dealer and the sole shareholder of CMC. TCFI pays
no distribution fees or expenses. The Acquiring Fund, however, has adopted a
distribution plan (the "Rule 12b-1 Plan") pursuant to Rule 12b-1 of the 1940 Act
which permits the Acquiring Fund to pay The Ohio Company, as the Acquiring
Fund's distributor, an amount paid periodically and calculated at an annual rate
not to exceed 0.25% of the average daily net asset value of the Acquiring Fund.
Such amount may be used by The Ohio Company to pay broker-dealers, 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. Under the Plan, a
Participating Organization may include The Ohio Company, its subsidiaries and
affiliates.
    
 
A sales charge is imposed upon the sale of both TCFI's and the Acquiring Fund's
shares equal to 4.5% of the public offering price (4.71% of the net amount
invested). Such sales charge is reduced on investments of $100,000 or more, as
set forth in the following table:

$1,000,000 or more.....................          0.50           0.50         0.40
</TABLE>
 
For each of TCFI and the Acquiring Fund, the sales charge may be waived under
certain specified conditions.
 
The expense ratio of the Acquiring Fund subsequent to the Reorganization is
expected to be higher than that of TCFI. See "THE PROPOSED
TRANSACTION -- REASONS FOR THE PROPOSED TRANSACTION." The annual total operating
expenses of TCFI as of September 30, 1995, were 0.70% as a percentage of average
net assets. Assuming the same level of net assets for the Acquiring Fund after
the Reorganization, it is estimated that the total annual operating expenses for
the Acquiring Fund stated as a percentage of average net assets would be 0.81%,
taking into account the proposed Rule 12b-1 fee waiver, and 1.06%, assuming no
Rule 12b-1 fee waiver.
 
COMPARISON OF PURCHASE AND REDEMPTION PROCEDURES.  Shares of TCFI and the
Acquiring Fund are offered at net asset value, plus the applicable sales charge
as described above, and may be purchased through The Ohio Company on each
Business Day. A "Business Day" is defined as each business day the New York
Stock Exchange is open for business and on any other day (other than a day on
which no shares of that fund are tendered for redemption and no order to
purchase any shares of that fund are received) where there is sufficient trading
in such fund's portfolio securities that its net asset value per share might be
materially affected by changes in the value of its portfolio securities. The
minimum initial investment in both TCFI and the Acquiring Fund is $1,000, the
minimum subsequent investment is $50 and there is no sales charge imposed upon
the reinvestment of dividends and distributions.
 
Redemption orders for shares of both TCFI and the Acquiring Fund must be placed
with CMC. Investors may redeem Shares of TCFI at the net asset value per share
next determined following the receipt by CMC of the following: (a) written or
telephonic notice to redeem, and (b) for Shares represented by certificates,
either the share certificates, properly endorsed, or properly executed
 
                                        5
<PAGE>   12
 
stock powers. Investors may redeem shares of the Acquiring Fund at the net asset
value per share next determined following the receipt by CMC of written or
telephonic notice to redeem.
 
COMPARISON OF EXCHANGE PRIVILEGES.  Shares of TCFI and of the Acquiring Fund may
be exchanged for shares of any other fund advised by The Ohio Company or CMC (a
"Cardinal Fund") at respective net asset values, although payment of a sales
charge equal to the difference, if any, between the sales charge payable upon
purchase of shares of such fund and the sales charge previously paid on the
shares to be exchanged may be applicable upon exchanges of shares for a Cardinal
Fund sold with a sales charge.
 
COMPARISON OF DIVIDEND POLICIES.  Each of TCFI and the Acquiring Fund declare
dividends and distributions periodically as they may so determine. Each of TCFI
and Acquiring Fund will distribute all of any capital gains at least annually.
In addition, shareholders of TCFI and the Acquiring Fund receive dividends and
distributions in the form of additional shares and not in cash unless otherwise
requested by the shareholder.
 
COMPARISON OF VOTING RIGHTS.  Each shareholder of TCFI is entitled to one vote
for each full share held and a proportionate fractional vote for each fractional
share held on each matter submitted to the vote of TCFI's shareholders,
regardless of the net asset value of such share. In addition, shareholders of
TCFI may cumulate their votes for purposes of voting for the election of
directors. Each shareholder of the Acquiring Fund, however, is entitled to one
vote for each dollar of value invested and a proportionate fractional vote for
any fraction of a dollar invested. Therefore, the number of full and fractional
votes per share of the Acquiring Fund will change depending upon the net asset
value of the Acquiring Fund's shares. In addition, shareholders of the Acquiring
Fund have no cumulative voting rights.
 
SPECIAL CONSIDERATIONS AND RISK FACTORS
 
Because the investment objectives, policies, strategies and restrictions of TCFI
and the Acquiring Fund are substantially similar, the overall level of
investment risk should not significantly change as a result of the
Reorganization. There can be no assurance that either TCFI or the Acquiring Fund
will achieve its investment objectives.
 
Like any investment program, an investment in either TCFI or the Acquiring Fund
entails certain risks. As a fund investing primarily in common stocks, TCFI and
the Acquiring Fund are subject to stock market risk, i.e., the possibility that
stock prices in general will decline over short or even extended periods.
 
The Acquiring 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 Acquiring Fund will not invest more than 10% of
its total assets in such derivatives at any one time.
 
The following discussion is qualified in its entirety by the disclosure set
forth in the Acquiring Fund's Prospectus accompanying this Combined
Prospectus/Proxy Statement and TCFI's Prospectus. For additional information,
see "COMPARISON OF INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS" and
"ADDITIONAL COMPARATIVE INFORMATION," below.
 
REPURCHASE AGREEMENTS.  Securities held by each of TCFI and the Acquiring Fund
may be subject to repurchase agreements. Under the terms of a repurchase
agreement, TCFI or the Acquiring Fund, as the case may be, acquires 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 its investment
adviser deems creditworthy under guidelines approved by the respective Board of
Directors/Trustees. At the time of purchase, the bank or securities dealer
agrees to repurchase the underlying securities 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. Under the
 
                                        6
<PAGE>   13
1940 Act, repurchase agreements are considered to be loans by TCFI and the
Acquiring Fund. Each of TCFI and the Acquiring 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 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 investment adviser will be responsible for continuously
monitoring such requirements. In the event of a bankruptcy or other default of a
seller of a repurchase agreement, TCFI or the Acquiring Fund (as the case may
be) 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 seeking 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.
 
INVESTMENT COMPANY SECURITIES.  Each of TCFI and the Acquiring 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. Such
funds intend to invest in the securities of other investment companies which, in
the opinion of its investment adviser, will assist such Fund in achieving its
objectives and of other money market mutual funds for purposes of short-term
cash management. Their investment in such other investment companies may result
in the duplication of fees and expenses, particularly investment advisory fees.
 
FOREIGN SECURITIES.  Unlike TCFI, the Acquiring 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"). Unsponsored ADRs may be less
liquid than sponsored ADRs, and there may be less information available
regarding the underlying foreign issuer for unsponsored ADRs. 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. 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. The Acquiring Fund will acquire securities issued by foreign
issuers only when CMC believes that the risks associated with such investments
are minimal.
 
PUT AND CALL OPTIONS.  Subject to its investment policies and for purposes of
hedging against market risks related to its portfolio securities, the Acquiring
Fund may purchase put and call options on securities. TCFI may not acquire put
and call options.
 
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 Acquiring Fund will purchase put options only on securities in
which the Acquiring Fund may otherwise invest. The Acquiring Fund may also
engage in writing call options from time to time as the Adviser deems
appropriate. The Acquiring Fund will write only covered call options (options on
securities owned by the Acquiring Fund). In order to close out a call option it
has written, the Acquiring 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 Acquiring Fund
previously has written. When a portfolio security subject to a call option is
sold, the Acquiring Fund will effect a closing purchase transaction to close out
any existing call option on that security. If the Acquiring 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 Acquiring Fund delivers the
underlying security upon exercise. Under normal market conditions, it is
 
                                        7
<PAGE>   14
 
not expected that the underlying value of portfolio securities subject to such
options would exceed 25% of the net assets of the Acquiring Fund.
 
The Acquiring 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 Acquiring Fund will write only covered index call options.
Through the writing or purchase of index options the Acquiring 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 Acquiring Fund owns or intends to
purchase probably will not correlate perfectly with movements in the level of an
index and, therefore, the Acquiring 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 Acquiring 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.  Unlike TCFI, the Acquiring 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 Acquiring 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 Acquiring 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 Acquiring Fund, through the purchase of such
contracts, can attempt to secure better rates or prices for the Acquiring 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 Acquiring 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 Acquiring 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 Acquiring Fund's total assets. Futures transactions will be limited
to the extent necessary to maintain the Acquiring Fund's qualification as a
regulated investment company.
 
Futures transactions involve brokerage costs and require the Acquiring Fund to
segregate assets to cover contracts that would require it to purchase
securities. The Acquiring 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 Acquiring Fund had not entered into any futures transactions. In
addition, the value of the Acquiring Fund's futures positions may not prove to
be perfectly or even highly correlated with the value of its portfolio
securities, limiting the Acquiring 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.

THE PROPOSED TRANSACTION
 
AGREEMENT AND PLAN OF REORGANIZATION AND LIQUIDATION.  The Plan provides that
all of the assets of TCFI as of the Exchange Date (as defined in the Plan) will
be transferred to the Acquiring Fund in exchange for shares of the Acquiring
Fund and the assumption by the Acquiring Fund of all of the liabilities of TCFI.
The Exchange Date is expected to be on or about March 31, 1996, subject,
however, to the receipt by TCFI and the Group of any necessary order of
exemption from the Commission with respect to the Reorganization. A copy of the
Plan is attached as Exhibit A to this Combined Prospectus/Proxy Statement.
Although portions of the Plan are summarized below, this summary is qualified in
its entirety by reference to the Plan.
 
Promptly after the Exchange Date, TCFI will distribute the shares of the
Acquiring Fund to TCFI's shareholders of record as of the close of business on
the Exchange Date. The shares of the Acquiring Fund which will be issued for
distribution to TCFI's shareholders will be equal in aggregate value to the
Shares of TCFI held as of the Valuation Time (as defined in the Plan). All
issued and outstanding Shares of TCFI will be cancelled on TCFI's books. Shares
of the Acquiring Fund will be represented only by book entries; no share
certificates will be issued.
 
The consummation of the Reorganization is subject to the satisfaction of a
number of conditions set forth in the Plan, including approval by shareholders
of TCFI. The Plan also may be terminated and the Reorganization abandoned by
TCFI and the Acquiring Fund by mutual consent of their respective
directors/trustees. If the consummation of the Reorganization is so abandoned,
no party shall be liable to the other party for any damages resulting therefrom.
If the Reorganization is otherwise not consummated by reason of either party's
being unwilling or unable to go forward (other than by reason of the
non-fulfillment or failure of certain conditions to such party's obligations),
such party will pay directly all reasonable fees and expenses incurred by the
other party in connection with the Reorganization.
 
The Reorganization also is subject to the condition of obtaining an opinion of
counsel to the effect that the Reorganization constitutes a tax-free
reorganization for federal income tax purposes and any necessary written order
of exemption from the Commission exempting the Reorganization from the
provisions of Section 17(a) of the 1940 Act.
 
Except as otherwise provided below, all fees and expenses incurred by a party in
connection with the Plan will be paid by the party directly incurring such costs
except where a party is unwilling or unable to go forward (other than for lack
of requisite shareholder approval or breach by the other party in its covenants)
in which case such party will pay all reasonable fees and expenses of the other
party. The Ohio Company will pay the costs of the Reorganization. TCFI will pay
those costs associated with that portion of the Meeting relating to customary
annual meeting matters (e.g.,election of directors), and the Acquiring Fund will
bear its organizational costs.
 
   
Finally, the Reorganization is subject to TCFI shareholders' approval of Issue 2
described below. Generally, TCFI is asking shareholders to approve the deletion
of its fundamental policy with respect to related party transactions. Such
policy, if not deleted, may be interpreted to prevent TCFI from selling all of
its portfolio securities to the Acquiring Fund pursuant to the terms of the
Plan.
    
 
Under Ohio law, shareholders of record as of the Record Date who vote against
the proposed Reorganization, or who refrain from voting thereon, may within ten
(10) days after the vote is taken express their dissent and demand payment to
them of the fair cash value of their shares, such value to be determined as of
the day immediately preceding the date on which the vote was taken. Any such
demand must be in writing, stating the address of such shareholder, the number
and class of shares as to which relief is sought and the amount claimed as the
fair cash value thereof and must be delivered to TCFI within ten (10) days after
the vote on the Reorganization is taken. Thereafter, unless TCFI and the
dissenting shareholder have come to an agreement with respect to the fair cash
value of the shares as to which relief is sought, either party may, within three
months after service of demand by the shareholder, file a petition in the Court
of Common Pleas in Franklin County, Ohio, for appraisal
 
                                        9
<PAGE>   16
 
and determination of the fair cash value. The foregoing is a summary of the
rights of dissenters, the full provisions of which are set forth in the Ohio
General Corporation Law and particularly Section 1701.85, Ohio Revised Code.
 
However, the Commission has taken the position that Rule 22c-1 of the 1940 Act
limits a shareholder of a registered investment company, dissenting from a
reorganization, from receiving for his shares an amount different from the net
asset value thereof, next computed after receipt of the written dissent. This
position, if accepted by an appropriate court, would establish net asset value
next computed after receipt of the written dissent as the amount a dissenting
shareholder would receive and would supersede contrary provisions of law. If the
Plan is duly approved by shareholders, all shareholders of TCFI as of the
Exchange Date, including those that voted against the approval of the Plan, will
receive shares of the Acquiring Fund. All shareholders of TCFI have the right at
any time up to the next business day preceding the Exchange Date to redeem their
Shares at net asset value according to the procedures set forth in TCFI's
Prospectus.
 
This summary does not purport to be a complete description of the Plan and is
subject to the terms and conditions of the Plan set forth in Exhibit A.
 
   
REASONS FOR THE PROPOSED TRANSACTION.  Currently, TCFI is a separate,
stand-alone investment company organized in 1966. The Group was organized as a
series investment company in 1993, and in October and November 1995, its Board
of Trustees created the Acquiring Fund with substantially similar investment
objectives, policies and restrictions to those of TCFI. Because of the
similarity between TCFI and the Acquiring Fund, the risks involved with an
investment in the Acquiring Fund are not expected to be significantly greater
than those associated with an investment in TCFI. The Acquiring Fund has been
established for purposes of effecting the Reorganization and will not commence
operations prior to the Exchange Date.
    
 
The transactions contemplated by the Plan were presented to the Board of
Directors of TCFI for their consideration at meetings held on October 20, 1995,
and November 13, 1995. The Board of Directors of TCFI concluded unanimously that
the Reorganization is in the best interests of TCFI and that the interests of
the existing shareholders of TCFI will not be diluted by the Reorganization.
 
The Board of Directors of TCFI, in reaching this conclusion, considered the
costs resulting from the separate operation of TCFI and the proposed costs of
operating the Acquiring Fund as provided by The Ohio Company, in light of their
substantially similar investment objectives, policies, restrictions, Boards of
Directors/Trustees, officers and service providers. The Board also considered
the operating and compliance efficiencies that could result from moving the
operation of TCFI from a stand-alone investment company to a separate portfolio
of a series investment company. The investment objective of the Acquiring Fund
varies from that of TCFI in that the Acquiring Fund does not limit achieving its
investment objectives through investing in American businesses. Specifically,
the Acquiring Fund intends to invest, from time to time, in ADRs, as more fully
described above under "SPECIAL CONSIDERATIONS AND RISK FACTORS -- FOREIGN
SECURITIES." The investment restrictions of the Acquiring Fund which were
approved by the Board of Trustees of the Group also vary somewhat from the
restrictions of TCFI; however, such differences reflect a more uniform and
flexible set of investment restrictions that are currently in place for each of
the other series or portfolios of the Group. Such restrictions were approved to
help achieve greater compliance efficiencies by having each series of the Group
have the same or substantially the same investment restrictions and to give the
Acquiring Fund the ability to engage in options and futures transactions as
described above under "Special Considerations and Risk Factors."
 
One of the operating efficiencies expected to be achieved is that under Ohio law
and the Group's Declaration of Trust an annual meeting of shareholders of the
Acquiring Fund is not required. TCFI as an Ohio corporation is required to hold
such a meeting. Also, certain fixed costs associated with the operation of TCFI
when incurred by the Acquiring Fund as part of the Group would decrease on a per
share basis since such costs would be spread over a larger pool of assets, e.g.,
certain legal and printing fees, while maintaining the same services by the same
or affiliated service providers.
 
                                       10
<PAGE>   17
 
In particular, the Board considered the anticipated expense ratios of the
Acquiring Fund, the structure of the Group, the experience of the service
providers of the Acquiring Fund and the level of service to be provided to the
shareholders of the Acquiring Fund, as represented by The Ohio Company,
including the greater resources that could be dedicated to managing the
Acquiring Fund's portfolio securities and marketing the Acquiring Fund and
providing shareholder services.
 
TCFI's Board also considered the higher fees charged to the Acquiring Fund
compared to those of TCFI. With respect to the higher investment advisory fee,
TCFI's Board considered CMC's and The Ohio Company's express commitment of
additional investment management personnel and other resources to manage the
portfolio of the Acquiring Fund. With respect to the Rule 12b-1 fee, TCFI's
Directors concluded that the payment of such fees will improve the servicing of
shareholder accounts by broker-dealers and is necessary to compete successfully
through a broker-dealer distribution channel in today's marketplace when
competing funds pay a similar or higher fee to such brokers. Thus, TCFI's Board
determined that the payment of such Rule 12b-1 fees will promote fund sales and
discourage fund redemptions and that a larger fund will be able to spread its
fixed costs (exclusive of those costs based upon a percentage of net assets)
over a wider based and to achieve better portfolio diversification.
 
The Board of Directors of TCFI based its decision to approve the proposed
transaction upon its consideration of a number of factors, including those
described above and the following:
 
     (1) the terms and conditions of the Reorganization and whether it would
     result in a dilution of the existing shareholders' interests;
 
     (2) the similarity of TCFI's investment objectives, strategies and policies
     with those of the Acquiring Fund, as well as the views of CMC that any
     differences between the investment policies and restrictions of TCFI and
     the Acquiring Fund should not significantly increase investment risks;
 
     (3) the experience and resources of CMC with respect to providing
     investment management services, CMC's commitment to increase the personnel
     and resources dedicated to the management of the Acquiring Fund's portfolio
     investments and the experience of and quality of services to be provided by
     the Acquiring Fund's other service providers;
 
     (4) the projected expense ratios and information regarding fees and
     expenses of TCFI, the Acquiring Fund and other similar funds and the
     services being offered to shareholders;
 
     (5) the conditioning of the Reorganization on the receipt of a legal
     opinion confirming the absence of any adverse federal tax consequences to
     TCFI or its shareholders resulting from the Reorganization; and
 
     (6) other factors as it deemed relevant.
 
In particular, the Board considered the following per share operating expense
ratios (total annual operating expenses expressed as a percentage of average net
assets) for shares of TCFI for the year ended September 30, 1995, and as
estimated for the shares of the Acquiring Fund for the period following the
effective date of the Reorganization and ending September 30, 1996, after giving
effect to the Reorganization:

  Fund, as a percentage of average net assets, are estimated to be 1.06%.

DESCRIPTION OF THE SECURITIES TO BE ISSUED.  Ownership in the Acquiring Fund is
represented by units of beneficial interest, without par value, of The Cardinal
Group (the "Group"), which is an open-end investment company of the management
type, organized as an Ohio business trust on March 23, 1993. The Acquiring Fund
is currently one of six separate series of the Group. Like TCFI, the Acquiring
Fund is diversified, as that term is defined in the 1940 Act. Currently there is
only one class of shares for the Acquiring Fund. Shareholders of the Acquiring
Fund are entitled to one vote for each dollar of value invested and a
proportionate fractional vote for any fraction of a dollar invested. See
"ADDITIONAL COMPARATIVE INFORMATION."
 
FEDERAL INCOME TAX CONSEQUENCES.  As a condition to the closing of the
Reorganization, TCFI and the Group must receive a favorable opinion from Baker &
Hostetler, counsel to both TCFI and the Group, substantially to the effect that,
for federal income tax purposes: (a) the Reorganization will constitute a
"tax-free" reorganization within the meaning of Section 368(a) of the Internal
Revenue Code of 1986, as amended (the "Code"); (b) no gain or loss will be
recognized by the Acquiring Fund or TCFI as a result of the Reorganization; (c)
no gain or loss will be recognized by shareholders of TCFI upon the exchange of
their Shares of TCFI for shares of the Acquiring Fund; (d) the tax basis of the
Acquiring Fund shares received by shareholders of TCFI pursuant to the
Reorganization will be the same as the basis of the Shares of TCFI held
immediately prior to the Reorganization; (e) the holding period of the Acquiring
Fund shares so received will include the period during which TCFI shareholder
held Shares of TCFI, provided such Shares were held as a capital asset; (f) the
tax basis of TCFI's assets acquired by the Acquiring Fund will be the same as
the basis of such assets immediately prior to the Reorganization; and (g) the
holding period of such assets will include the period during which those assets
were held by TCFI. The Group and TCFI do not intend to seek a private letter
ruling with respect to the tax effects of the Reorganization.
 
   
CAPITALIZATION.  The following table shows the capitalization of TCFI as of
September 30, 1995. The Acquiring Fund has no and will have no assets or
liabilities or commence operations immediately prior to the consummation of the
Reorganization. THEREFORE, NO PRO FORMA INFORMATION GIVING EFFECT TO THE
REORGANIZATION IS PROVIDED.

COMPARISON OF INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS
 
INVESTMENT OBJECTIVES AND POLICIES.  The investment objectives and policies of
TCFI are substantially similar to those of the Acquiring Fund. The investment
objectives of TCFI and Acquiring Fund are "fundamental," which means that they
may not be changed without the consent of a majority of such fund's outstanding
shares, as defined in the 1940 Act.
 
The investment objectives of TCFI are to achieve long-term growth of capital and
income through selective participation in the long-term progress of American
businesses and industries. Current income, while a factor in portfolio
selection, is secondary to the primary objective. The investment objectives of
the Acquiring Fund are long-term growth of capital and income. Current income is
a secondary objective.
 
The policy of each of TCFI and the Acquiring Fund is generally to invest in
equity securities of companies which, in the opinion of the investment adviser,
are growth oriented. The securities purchased by TCFI and the Acquiring 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. Current income, while a factor in portfolio selection, is secondary to
the primary objective. This policy of normally investing in equity securities
believed to have a potential for long-term capital
 
                                       12
<PAGE>   19
 
   
appreciation means that the assets of TCFI and the Acquiring 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, such Funds' equity position should be
reduced. At such times, and otherwise for cash management purposes, each of TCFI
and the Acquiring 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
Acquiring Fund, however, unlike TCFI, may also invest in foreign securities
including ADRs.
    
 
INVESTMENT RESTRICTIONS
 
The fundamental investment restrictions of TCFI and the Acquiring Fund are
similar except for the following differences:
 
(1) TCFI may not purchase the securities of any issuer if such purchase would
cause more than 5% of TCFI's total assets upon such purchase to be invested in
the securities of any one issuer (not including the government of the United
States or corporations which are the instrumentalities of the United States) nor
may it purchase the securities of any issuer if such purchase would cause TCFI
to hold (i) more than 10% of the voting securities of such issuer, (ii) more
than 10% of all debt securities of such issuer taken as a class, or (iii) more
than 10% of all equity securities of such issuer preferred in any way over the
common stock of such issuer taken as a class. The Acquiring Fund may not
purchase securities of any one issuer, other than obligations issued or
guaranteed by the U.S. Government or its agencies or instrumentalities, if,
immediately after such purchase, more than 5% of the value of the Acquired
Fund's total assets would be invested in such issuer or the Acquired Fund would
hold more than 10% of the outstanding voting securities of the issuer, except
that up to 25% of the value of the Acquired 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) TCFI may not concentrate more than 25% of the value of the total assets of
TCFI (determined at the date of acquisition) in investments in any particular
industry. The Acquiring Fund has a similar policy except that its policy
expressly includes the Commission's position that 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. The Acquiring
Fund's policy is further qualified as follows: (a) 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 (b) 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) TCFI may not purchase securities on margin. The Acquiring Fund has a similar
restriction except that the Acquiring Fund may use short-term credit necessary
for clearance of purchases of portfolio securities and may also make margin
payments as may be necessary in connection with derivative securities
transactions.
 
(4) TCFI has a policy of not purchasing or selling commodities, commodity
contracts or futures contracts. The Acquiring Fund has a similar policy with
respect to commodities and commodity contracts except it may engage in such
transactions to the extent disclosed to shareholders in its current Prospectus.
 
(5) TCFI may not write, purchase or sell puts, calls or combinations thereof.
The Acquiring Fund has no such restriction.
 
(6) TCFI may not mortgage, pledge or hypothecate any assets to a greater extent
than 15% of its gross assets taken at cost. The Acquiring Fund has a
non-fundamental policy that it may not mortgage or hypothecate the Acquiring
Fund's assets in excess of one-third of the Acquiring Fund's total assets.
 
                                       13
<PAGE>   20
 
(7) TCFI may not purchase any securities from or sell any securities to (other
than stock issued by TCFI) officers or directors of TCFI, any person or
organization furnishing managerial or advisory services to TCFI, or related
classes of persons as principals. The Acquiring Fund has no similar policy.
 
(8) TCFI may not invest in companies for the purpose of exercising control or
management thereof. The Acquiring Fund has no similar policy.
 
(9) TCFI may not change its classification as a "management company" under
Section 4 of the 1940 Act or change its subclassifications as an "open-end
company" or as a "diversified company" under Section 5 of the 1940 Act. The
Acquiring Fund has no such policy although the 1940 Act requires that
shareholders approve any such change by the Acquiring Fund.
 
In addition, the Acquiring Fund has the following non-fundamental investment
restrictions. Except as noted below, these non-fundamental investment
restrictions are substantially similar to fundamental investment restrictions of
TCFI. As discussed above, however, fundamental restrictions of a fund may not be
changed without a vote of a majority of the outstanding voting securities of the
fund; non-fundamental policies may be changed without a shareholder vote. As a
consequence, the following policies could be modified, or eliminated, by the
Group with respect to the Acquiring Fund without shareholder approval.
 
(1) The Acquiring Fund may not engage in any short sales. TCFI has a similar
fundamental policy except that TCFI may make short sales of securities to the
extent that the same are owned by TCFI (i.e., short sales "against the box").
 
(2) The Acquiring Fund may not purchase or otherwise acquire any securities if,
as a result, more than 15% of the Acquiring Fund's net assets would be invested
in securities that are illiquid. In addition, the Acquiring Fund may not invest
more than 15% of its total assets in securities which are restricted as to
disposition. TCFI has a fundamental policy that provides that it may not
purchase securities subject to restrictions on disposition under the Securities
Act of 1933 if at the time of acquisition more than 5% of the total assets of
TCFI would be invested in such securities.
 
(3) The Acquiring Fund may not purchase or retain any securities of an issuer
if, to the knowledge of the Group, the officers and trustees of the Group or the
officers and directors of CMC individually owning more than 1/2 of 1% of the
securities of such issuer together own beneficially more than 5% of the
securities of such issuer.
 
(4) The Acquiring Fund may not purchase securities of enterprises which have a
record of less than three years' continuous operation, if such purchase would
cause more than 10% of the total assets of the Acquiring Fund to be invested in
the securities of such enterprises. TCFI's fundamental policy as to such
securities is limited to 5% of its total assets.
 
Finally, the Acquiring Fund has the non-fundamental policy that it may not
purchase participations or direct interests in oil, gas or other mineral
exploration or development programs (although investments by the Acquiring Fund
in marketable securities of companies engaged in such activities are not
prohibited by this restriction). TCFI has no such restriction.
 
   
PORTFOLIO MANAGERS.  Since CMC is a wholly owned subsidiary of The Ohio Company
and serves as the investment adviser to the Acquiring Fund, the person currently
serving as portfolio manager for TCFI intends to serve after the Reorganization
as portfolio manager for the Acquiring Fund.
    
 
It is not anticipated that the above-mentioned differences in investment
policies and restrictions will, individually or in the aggregate, result in an
significant variation between the level of investment risks associated with an
investment in TCFI. For a more complete description of the Acquiring Fund's
investment policies and restrictions, including relevant risk factors, see "WHAT
ARE THE INVESTMENT OBJECTIVES AND POLICIES OF THE FUND?" in the Acquiring Fund's
Prospectus and "INVESTMENT OBJECTIVES AND POLICIES" in the Acquiring Fund's
Statement of Additional Information. For a more complete description of TCFI's

year ended September 30, 1995. This is in comparison to a gain of 23.1% for the
average growth and income fund as tracked by Lipper Analytical Services, Inc. As
the stock market rebounded from a sluggish previous year, technology issues led
the advances. Although technology stocks represented roughly 5% of TCFI's assets
throughout the year, this concentration was obviously not enough for TCFI to
keep pace with the market. Additionally, the underperformance in the first
fiscal quarter of this year, due to holdings of financial and cyclical issues,
hindered TCFI's first few month's results.
 
Over the past twelve months, TCFI benefited from strong performance in
technology stocks such as Hewlett Packard, Intel, and Tektronics. Also
benefitting performance were holdings in bank and finance related issues such as
Bank One, Huntington, and Beneficial.
 
In contrast, TCFI's holdings in energy, insurance, and certain industrial
issues, while up, did not outperform the indices. Slower economic activity and
concerns over pricing held back gains with a number of these issues.
 
New to TCFI's holdings were a diverse group of stocks. Additions during the past
year included Mylan Labs, Coastal Corporation, U.S. Healthcare, Compaq
Computers, Marsh & McLennan, and Dun & Bradstreet. All are strong financially
and hold large market share positions in their respective industries.
 
Combined, TCFI's holdings compare favorably to the market when viewed in context
of management's disciplines and philosophy.

                               THE ACQUIRING 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, who are elected
by the shareholders of the Group's series or portfolios, including the Acquiring
Fund, and who 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.
 
   
INVESTMENT ADVISER.  The Acquiring Fund is advised by CMC. CMC was established
as an Ohio corporation on March 21, 1980, and has been providing investment
advisory services to open-end management investment companies like TCFI since
1980. It is intended that, upon completion of the Reorganization, Mr. Bevilacqua
will be responsible for the day-to-day management of the Acquiring Fund's
portfolio. For its services as investment adviser, CMC receives a fee, which is
calculated daily and paid monthly, at an annual rate of 0.60% of the average
daily net assets of the Acquiring Fund.
    
 
                                       17
<PAGE>   24
 
For a complete description of the Acquiring Fund's advisory arrangements, see
the section in the Acquiring Fund's Prospectus entitled "WHO MANAGES MY
INVESTMENT IN THE FUND? -- Investment Adviser and Manager."
 
   
DIVIDEND AND TRANSFER AGENT AND FUND ACCOUNTANT.  CMC, 215 East Capital Street,
Columbus, Ohio 43215, also serves as the Acquiring Fund's Dividend and Transfer
Agent. In consideration of such services, the Acquiring Fund has agreed to pay
CMC an annual fee, paid monthly, equal to $18 per shareholder account, plus
out-of-pocket expenses.
    
 
In addition, CMC provides certain fund accounting services for the Acquiring
Fund. CMC receives a fee from the Acquiring Fund for such services equal to a
fee computed daily and paid periodically at an annual rate of .03% of the
Acquiring Fund's average daily net assets of $100 million or less and .01% of
the Acquiring Fund's average daily net assets in excess of $100 million.
 
For a complete description of these arrangements and the other expenses borne by
the Acquiring Fund, see the sections in the Acquiring Fund's Prospectus entitled
"WHO MANAGES MY INVESTMENT IN THE FUND? -- Dividend and Transfer Agent and Fund
Accountant."
 
   
DISTRIBUTOR.  The Ohio Company also serves as the distributor of the Acquiring
Fund's Shares pursuant to a distribution agreement.
    
 
   
Pursuant to Rule 12b-1 under the 1940 Act, the Group has adopted a Rule 12b-1
Plan under which the Acquiring Fund is authorized to pay The Ohio Company, as
the Acquiring Fund's principal underwriter, a periodic amount calculated at an
annual rate not to exceed .25% of the average daily net asset value of the
Acquiring Fund. Such amount may be used by The Ohio Company to pay
broker-dealers, 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's subsidiaries, and its
affiliates.
    
 
As authorized by the Plan, The Ohio Company has agreed to provide certain
shareholder services in connection with shares of the Acquiring Fund purchased
and held by The Ohio Company for the accounts of its customers and shares of the
Acquiring Fund purchased and held by customers of The Ohio Company directly,
including, but not limited to, answering shareholder questions concerning the
Acquiring Fund, providing information to shareholders on their investments in
the Acquiring 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
shares held during the period in customer accounts for which The Ohio Company
has provided services under the Plan. Such fees paid by the Group will be borne
solely by the Acquiring Fund.
 
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.
 
   
For a complete description of these arrangements, see the section in the
Acquiring Fund's Prospectus entitled "WHO MANAGES MY INVESTMENT IN THE
FUND? -- Distribution Plan."
    
 
For fiscal period ending September 30, 1996, The Ohio Company has agreed to
waive all of such 12b-1 fees.
 
   
CUSTODIAN.  The Acquiring Fund has also appointed Fifth Third as the Acquiring
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
Acquiring Fund.
    
 
   
COUNSEL.  Baker & Hostetler, 65 East State Street, Columbus, Ohio 43215, also
serves as counsel to the Acquiring Fund.
    
 
                                       18
<PAGE>   25
 
   
INDEPENDENT ACCOUNTANTS.  KPMG Peat Marwick LLP, Two Nationwide Plaza, Columbus,
Ohio 43215, has been selected to serve as the independent accountants for the
Acquiring Fund, and, as such, will audit the financial statements of the
Acquiring Fund.
    
 
   
MANAGEMENT DISCUSSION OF FUND PERFORMANCE.  No management discussion of fund
performance is included since the Acquiring Fund has not yet commenced
operations.
    
 
   
CERTAIN FINANCIAL INFORMATION.  The Prospectus for TCFI contains information on
per share income, capital changes and performance calculations under the caption
"FINANCIAL HIGHLIGHTS."
    
 
   
The Acquiring Fund has not yet commenced operations and has no and will have no
assets or liabilities prior to the consummation of the Reorganization.
Therefore, no information regarding per share income and capital changes is
available. For information regarding performance calculations and comparisons,
see the information under the caption "PERFORMANCE INFORMATION" in the Acquiring
Fund's Prospectus.
    
 
   
COMPARISON OF RIGHTS OF SECURITY HOLDERS.  TCFI is an Ohio corporation,
registered under the 1940 Act as an open-end investment company of the
management type. TCFI was incorporated on September 16, 1966, under the laws of
Ohio. The Group is an Ohio business trust, registered under the 1940 Act as an
open-end investment company of the management type. The Group was established
under a Declaration of Trust dated as of March 23, 1993. TCFI is authorized to
issue 30,000,000 shares of common stock, without par value. The Group is
authorized to issue an unlimited number of shares of beneficial interest, which
shares may be divided into one or more series or separate classes of shares. The
Acquiring Fund is one of six series of the Group. The other five series of the
Group are Cardinal Government Obligations Fund, Cardinal Government Securities
Money Market Fund, Cardinal Tax Exempt Money Market Fund, Cardinal Balanced Fund
and Cardinal Aggressive Growth Fund.
    
 
Each share of TCFI represents an equal proportionate interest in TCFI with each
other share. Shares are entitled upon liquidation to a pro rata share of the net
assets of TCFI. Shares of TCFI issued pursuant to TCFI's Articles of
Incorporation are fully paid and nonassessable and have no preemptive or other
right to subscribe for any additional shares.
 
Shares of the Acquiring Fund, once properly issued and outstanding, are fully
paid and nonassessable and have no preference as to conversion, exchange,
dividends, retirement or other features, and have no preemptive or appraisal
rights.
 
Shareholders of TCFI are entitled to one vote for each full share held and a
proportionate fractional vote for each fractional share held. Shareholders of
the Acquiring Fund are entitled to one vote for each dollar of value invested
and a proportionate fractional vote for any fraction of a dollar invested.
Shareholders of TCFI may cumulate their votes for purposes of the election of
its Directors as described above under "GENERAL." TCFI currently holds an annual
meeting of shareholders.
 
   
Shareholders of the Acquiring Fund have no cumulative voting rights, which means
that the holders of a plurality of the shares voting for the election of the
Group's Board of Trustees can elect all of the Group's Board of Trustees if they
choose to do so. The Group does not intend to hold annual meetings of
shareholders, except as required under its Declaration of Trust or the 1940 Act.
Shareholders of the Acquiring Fund will vote in the aggregate with other
shareholders of the Group and not by series or portfolio except as otherwise
expressly required by law. For example, shareholders of the Acquiring 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 Acquiring 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 Acquiring Fund's investment advisory agreement or
any of the Acquiring Fund's fundamental policies.
    
 
Therefore, after the Reorganization, shareholders of the Acquiring Fund alone
will not be able to elect the Trustees of the Group or ratify the selection of
independent accountants but will vote with all the
 
                                       19
<PAGE>   26
 
other shareholders of the Group on such issues if and when presented to
shareholders. In addition, since the Group currently does not intend to hold
annual meetings unless otherwise required to do so, it can not be determined
when shareholders of the Acquiring Fund will next be entitled to vote for the
election of Trustees or the ratification of the selection of independent public
accountants.
 
   
For a complete description of the respective attributes of TCFI's and the
Group's shares, including how to purchase, redeem or exchange shares and certain

be, and its shareholders, and dividend and distribution policies, see the

which is incorporated herein by reference, and in TCFI's Statement of Additional
Information dated January 19, 1996. Copies of the Prospectus and the Statement

this Combined Prospectus/Proxy Statement. The Statement of Additional
Information is incorporated by reference herein and may be obtained by calling
the Group at 1-800-282-9446.
    
 
TCFI'S BOARD OF DIRECTORS AND MANAGEMENT RECOMMEND APPROVAL OF THE PLAN.
 
                DELETION OF TCFI'S FUNDAMENTAL POLICY REGARDING
   
                     RELATED PARTY TRANSACTIONS -- ISSUE 2
    
 
   
TCFI's fundamental policies currently provide that TCFI may not purchase any
securities from or sell any securities to (other than stock issued by TCFI)
officers or directors of TCFI, any person or organization furnishing managerial
or advisory services to TCFI, or related classes of persons as principals
[emphasis added]. Because this policy is unclear as it relates to the
Reorganization, but could be read to prohibit the Reorganization (i.e., because
the Group may be a person related to The Ohio Company), shareholders are being
asked to approve the deletion of this policy.
    
 
The 1940 Act contains limitations on transactions between investment companies
and their affiliates which will continue to apply to TCFI if the above policy is
deleted.
 
   
Approval of the deletion of TCFI's fundamental policy regarding related party
transactions requires the affirmative vote of a majority of the outstanding
voting securities of TCFI, defined as the affirmative vote, at a meeting of
shareholders duly called, of the lesser of (a) 67% or more of the votes of the
shareholders of TCFI present at the meeting at which the holders of more than
50% of the votes attributable to shareholders of record of TCFI are represented
in person or by proxy, or (b) the holders of more than 50% of the outstanding
votes of shareholders of TCFI. TCFI'S BOARD OF DIRECTORS AND ITS MANAGEMENT
RECOMMEND APPROVAL OF THIS PROPOSED DELETION. IF ISSUE 2 IS NOT APPROVED, SUCH
FUNDAMENTAL POLICY WILL REMAIN IN EFFECT AND THE REORGANIZATION WILL NOT BE
CONSUMMATED.
    
 
   
                 FIXING THE NUMBER OF DIRECTORS AND ELECTION OF
    
   
                          DIRECTORS -- ISSUES 3 AND 4
    
 
   
It is the present intention that the enclosed proxy will be used for the
purposes of voting in favor of fixing the number of directors at ten and the
election of each of the following ten nominees as a
    
 
                                       20
<PAGE>   27
 
   
director to hold office until the next annual meeting and until his successor is
elected and qualified. Each of the nominees is a member of the present Board of
Directors of TCFI and, except for Mr. Allen, each has been elected by
shareholder vote. Pursuant to Rule 14a-4(d) under the Securities Exchange Act of
1934, each nominee has consented to be named in this Combined Prospectus/Proxy
Statement and to serve if elected. It is not expected that any of the nominees
will decline or become unavailable for election, but in case this should happen,
the discretionary power given in the proxy may be used to vote for a substitute
nominee or nominees.

              AGREEMENT AND PLAN OF REORGANIZATION AND LIQUIDATION
 
Agreement and Plan of Reorganization and Liquidation ("Agreement") dated as of
December 1, 1995, by and between The Cardinal Group, an Ohio business trust
("TCG"), and The Cardinal Fund Inc., an Ohio corporation ("TCFI").
 
WHEREAS, TCG is registered under the Investment Company Act of 1940, as amended
("1940 Act"), as an open-end investment company of the management type and has,
or before the Exchange Date (as defined below) is expected to have, issued and
outstanding one class of shares of beneficial interest, without par value
("Shares"), for each of six series, one such series being The Cardinal Fund
(hereinafter sometimes referred to as the "Cardinal Fund" or the "Acquiring
Series"); and
 
WHEREAS, TCFI is registered under the 1940 Act as an open-end investment company
of the management type and currently has issued and outstanding one class of
common shares, without par value; and
 
WHEREAS, TCFI plans to transfer all of its assets, and to assign all of its
liabilities, to the Acquiring Series, in exchange for Shares of the Acquiring
Series (the "Acquiring Series Shares"), followed by the distribution of the
Acquiring Series Shares by TCFI to its shareholders, and followed by the
dissolution of TCFI, all upon the terms and provisions of this Agreement (the
"Reorganization"); and
 
WHEREAS, this Agreement is intended to be and is adopted as a plan of
reorganization and liquidation within the meaning of Section 368(a) of the
United States Internal Revenue Code of 1986, as amended (the "Code"); and
 
WHEREAS, the trustees of TCG have determined that the Reorganization is in the
best interests of TCG, and that the interests of its shareholders will not be
diluted as a result thereof; and
 
WHEREAS, the Board of Directors of TCFI has determined that the Reorganization
is in the best interests of TCFI and that the interests of its shareholders will
not be diluted as a result thereof;
 
NOW, THEREFORE, in consideration of the mutual promises herein contained, the
parties hereto covenant and agree as follows:
 
1. PLAN OF REORGANIZATION AND LIQUIDATION.
 
(a) Sale of Assets, Assumption of Liabilities.  Subject to the prior approval of
shareholders of TCFI and to the other terms and conditions contained herein
(including the obligation of TCFI to distribute to its shareholders all of its
investment company taxable income and net capital gain as described in Section
8(i) herein), TCFI agrees to sell, assign, convey, transfer and deliver to the
Acquiring Series, and the Acquiring Series agrees to acquire from TCFI on the
Exchange Date (as defined below), all of the Investments (as defined below),
cash and other assets of TCFI in exchange for that number of full and fractional
Acquiring Series Shares of the Acquiring Series having an aggregate net asset
value equal to the value of all assets of TCFI transferred to the Acquiring
Series, as provided in Section 4, less the liabilities of TCFI assumed by the
Acquiring Series.
 
b) Assets Acquired.  The assets to be acquired by the Acquiring Series from TCFI
shall consist of all of TCFI's property, including, without limitation, all
Investments, cash and dividends or interest receivables which are owned by TCFI
and any deferred or prepaid expenses shown as an asset on the books of TCFI as
of the Valuation Time described in Section 4.
 
(c) Liabilities Assumed.  Prior to the Exchange Date TCFI will endeavor to
discharge or cause to be discharged, or make provision for the payment of, all
of its known liabilities and obligations. The Acquiring Series shall assume all
liabilities, expenses, costs, charges and reserves of TCFI, contingent or
otherwise, including liabilities reflected in the unaudited statement of assets
and liabilities of TCFI
 
                                       A-1
<PAGE>   34
 
as of the Valuation Time, prepared by or on behalf of TCFI in accordance with
generally accepted accounting principles consistently applied from and after
September 30, 1995.
 
(d) Liquidation and Dissolution.  Upon consummation of the transactions
described in Section 1(a), 1(b) and 1(c) above, TCFI shall distribute in
complete liquidation to its shareholders of record as of the Exchange Date the
Acquiring Series Shares received by it, each TCFI shareholder of record being
entitled to receive that number of Acquiring Series Shares equal to the
proportion which the number of common shares, without par value, of TCFI held by
such shareholder bears to the total number of such shares of TCFI outstanding on
such date, and shall take such further action as may be required, necessary or
appropriate under TCFI's Articles of Incorporation, Ohio law and the Code to
effect the complete liquidation and dissolution of TCFI. TCFI will fulfill all
reporting requirements under the 1940 Act, both before and after the
Reorganization.
 
2. REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF TCFI.  TCFI represents and
warrants to and agrees with TCG and the Acquiring Series that:
 
(a) TCFI is a corporation validly existing under the laws of the State of Ohio
and has power to own all of its properties and assets and to carry out its
obligations under this Agreement. TCFI has qualified as a foreign corporation in
each jurisdiction where the ownership of its property and the conduct of its
business require qualification. TCFI has all necessary federal, state and local
authorizations to carry on its business as now being conducted and to fulfill
the terms of this Agreement, except as set forth in Section 2(l).
 
(b) TCFI is registered under the 1940 Act as an open-end investment company of
the management type, and such registration has not been revoked or rescinded and
is in full force and effect. TCFI has elected to qualify and has qualified as a
regulated investment company under Part I of Subchapter M of the Code as of and
since its first taxable year, and qualifies and intends to continue to qualify
as a regulated investment company for its taxable year ending upon its
liquidation. TCFI has been a regulated investment company under such sections of
the Code at all times since its inception.
 
(c) The statement of assets and liabilities, including the statement of
investments as of September 30, 1995, and the related statement of operations
for the year then ended, and statements of changes in net assets for each of the
two years in the period then ended, for TCFI, such statements having been
audited by KPMG Peat Marwick LLP, independent auditors of TCFI, have been
furnished to TCG. Such statement of assets and liabilities fairly present the
financial position of TCFI as of such date and such statements of operations and
changes in net assets fairly reflect the results of operations and changes in
net assets for the periods covered thereby in conformity with generally accepted
accounting principles, and there are no known material liabilities of TCFI as of
such dates which are not disclosed therein.
 
(d) The Prospectus of TCFI dated February 1, 1995 (the "TCFI Prospectus") and
the related Statement of Additional Information for TCFI dated February 1, 1995,
in the forms filed with the Securities and Exchange Commission and previously
furnished to TCG, did not as of their date and do not as of the date hereof
contain any 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.
 
(e) Except as may have been previously disclosed to TCG, there are no material
legal, administrative or other proceedings pending or, to the knowledge of TCFI
threatened against TCFI.
 
(f) There are no material contracts outstanding to which TCFI is a party, other
than as disclosed in the TCFI Prospectus and its corresponding Statement of
Additional Information, and there are no such contracts or commitments (other
than this Agreement) which will be terminated with liability to TCFI on or prior
to the Exchange Date.
 
(g) TCFI has no known liabilities of a material nature, contingent or otherwise,
other than those shown as belonging to it on its statement of assets and
liabilities as of September 30, 1995 and those incurred in the ordinary course
of TCFI's business as an investment company since that date. Prior to
 
                                       A-2
<PAGE>   35
 
the Exchange Date, TCFI will advise TCG of all known material liabilities,
contingent or otherwise, incurred by it subsequent to September 30, 1995,
whether or not incurred in the ordinary course of business.
 
(h) As used in this Agreement, the term "Investments" shall mean TCFI's
investments shown on the statement of assets and liabilities as of September 30,
1995 referred to in Section 2(c) hereof, as supplemented with such changes as
TCFI shall make after September 30, 1995 and prior to the date of this
Agreement, which changes have been disclosed to TCG, and changes made on and
after the date of this Agreement after advising TCFI of such changes, and
changes resulting from stock dividends stock split-ups, mergers and similar
corporate actions.
 
(i) TCFI has filed or will file all federal and state tax returns which, to the
knowledge of TCFI's officers, are required to be filed by TCFI and has paid or
will pay all federal and state taxes shown to be due on said returns or on any
assessments received by TCFI. All tax liabilities of TCFI have been adequately
provided for on its books, and no tax deficiency or liability of TCFI has been
asserted, and no question with respect thereto has been raised, by the Internal
Revenue Service or by any state or local tax authority for taxes in excess of
those already paid.
 
(j) As of both the Valuation Time and the Exchange Date and except for
shareholder approval and otherwise as described in Section 2(1), TCFI will have
full right, power and authority to sell, assign, transfer and deliver the
Investments and any other of its assets and liabilities to be transferred to TCG
and the Acquiring Series pursuant to this Agreement. At the Exchange Date,
subject only to the delivery of the Investments and any such other assets and
liabilities as contemplated by this Agreement, TCG and the Acquiring Series will
acquire the Investments and any such other assets subject to no encumbrances,
liens or security interests in favor of any third party creditor of TCFI and,
except as described in Section 2(k), without any restrictions upon the transfer
thereof.
 
(k) No registration under the Securities Act of 1933, as amended (the "1933
Act"), of any of the Investments would be required if they were, as of the time
of such transfer, the subject of a public distribution by either of TCFI or TCG,
except as previously disclosed to TCG by TCFI in writing prior to the date
hereof.
 
(l) No consent, approval, authorization or order of any court or governmental
authority is required for the consummation by TCFI of the transactions
contemplated by this Agreement, except such as may be required under the 1933

                                CARDINAL FUNDS

                                                                January 26, 1996
    
 
Dear Cardinal Government Obligations Fund Shareholder:
 
   
The Board of Trustees of Cardinal Government Obligations Fund (the "Trust")
recently reviewed and unanimously approved a proposal to reorganize the Trust
with and into a newly created series of The Cardinal Group (the "Group"). This
Agreement and Plan of Reorganization and Liquidation is described in the
accompanying Combined Prospectus/Proxy Statement and will be addressed at the
Annual Meeting of Shareholders on March 15, 1996.
    
 
The primary purpose of the proposed reorganization is to achieve certain
economies of scale by having the Trust become an additional series of the Group
rather than operate as a separate stand-alone investment company. By operating
more efficiently, we expect to realize cost savings through the elimination of
certain Annual Meeting expenses, a reduction of printing and mailing
expenditures, the lowering of regulatory filing expenses and the reduction of
professional fees. The Board determined that such a reorganization is in the
best interest of the Trust.
 
   
If the proposed reorganization is approved, you will receive shares of the newly
created series of the Group, also known as Cardinal Government Obligations Fund,
in exchange for your shares of the Trust. Shares received in this distribution
will be equal in value at the time of reorganization to your shares in the
Trust. There will be no adverse federal income tax consequences associated with
this distribution.
    
 
As a result of the reorganization, many features of the new series will be the
same as those of the Trust. For instance, the securities in the underlying
portfolio will remain the same. Purchase and redemption procedures will not
change. Slight differences in investment policies and restrictions are proposed
but are not expected to increase the level of risk associated with your
investment.
 
   
Operating expenses for the new series' shares are expected to be higher than
those of the Trust due to the addition of a Rule 12b-1 Plan. This increase will
enable us to remain competitive in today's mutual fund marketplace by investing
in the people and resources necessary to continue providing a high level of
service. Although operating expenses will be greater, the proposed level places
your investment company within the norms of its industry peer group.
    
 
   
Please read the accompanying materials carefully. For more details regarding the
proposed reorganization, direct any questions you may have to the Treasurer of
the Trust, Mr. James Schrack, at (800) 282-9446. IT IS VERY IMPORTANT THAT YOU
COMPLETE AND RETURN THE PROXY CARD AS SOON AS POSSIBLE.
    
 
Thank you for your support and investment in Cardinal Government Obligations
Fund.
 
                                          Sincerely,
 
                                          FRANK W. SIEGEL, CFA
                                          President
   
                                          Cardinal Government Obligations Fund
    
 
   
P.S.   YOUR VOTE IS VERY IMPORTANT TO US. PLEASE COMPLETE, SIGN, DATE AND RETURN

This Combined Prospectus/Proxy Statement is being furnished to shareholders of
Cardinal Government Obligations Fund, an Ohio business trust (the "Trust"), in
connection with the solicitation of proxies by the Board of Trustees of the
Trust to be used at the Annual Meeting of Shareholders of the Trust (the
"Meeting"), to be held at The Athletic Club of Columbus, 136 East Broad Street,
Columbus, Ohio 43215, on Friday, March 15, 1996, beginning at 9:30 A.M. (Eastern
Time).
    
 
In addition to the customary annual election of Trustees and ratification of the
selection of independent accountants, the Trustees of the Trust are seeking your
approval of an Agreement and Plan of Reorganization and Liquidation (the
"Plan"), which contemplates that Cardinal Government Obligations Fund (the
"Acquiring Fund"), a series or portfolio of The Cardinal Group (the "Group"),
will acquire all of the assets of and will assume all of the liabilities of the
Trust in exchange for shares of the Acquiring Fund.
 
Following such exchange, the shares of the Acquiring Fund received by the Trust
will be distributed to the Trust's shareholders and the Trust will be liquidated
and dissolved. This exchange and distribution transaction is sometimes referred
to herein as the "Reorganization."
 
This Combined Prospectus/Proxy Statement, which should be retained for future
reference, sets forth concisely the information about the Acquiring Fund that a
prospective investor, including shareholders of the Trust, should know before
investing. Additional information about the Reorganization and the Acquiring
Fund is contained in a separate Statement of Additional Information which has
been filed with the Securities and Exchange Commission (the "Commission") and is
available upon request without charge by calling the Group at (800) 282-9446 or
writing to the Group at the address set forth above. The Statement of Additional
Information bears the same date as this Combined Prospectus/Proxy Statement and
is incorporated by reference herein.
 
THE SHARES OF THE ACQUIRING 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 ACQUIRING FUND
INVOLVES CERTAIN INVESTMENT RISKS, INCLUDING THE POSSIBLE LOSS OF PRINCIPAL.
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
   EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
     SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
         PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY
             REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
 
Upon completion of the Reorganization, you will receive full and fractional
shares of the Acquiring Fund equal in value when issued to the shares of the
Trust owned by you immediately prior to the Reorganization. No commissions or
sales loads will be charged in connection with the Reorganization and there will
be no adverse federal income tax consequences. You should separately consider
any other tax consequences in consultation with your tax advisers.
 
As discussed in detail herein, the investment objectives and strategy of the
Acquiring Fund are substantially identical to those of the Trust. There are some
differences between investment policies and restrictions, as well as differences
in fee levels and in voting rights, which are described in detail

below. The Prospectus of the Acquiring Fund relating to its shares, dated
January 10, 1996, is incorporated by reference in this Combined Prospectus/Proxy
Statement and accompanies this Combined Prospectus/Proxy Statement.
    
 
   
The Trust's Prospectus dated January 19, 1996, contains additional information
about the Trust, has been filed with the Commission, is incorporated by
reference herein and is available without charge by writing the Trust at 155
East Broad Street, Columbus, Ohio 43215, or by calling the Trust at (800)
282-9446. Copies of documents requested will be sent by first-class mail to the
requesting shareholder within one business day of the request.

                                    GENERAL
 
   
This Combined Prospectus/Proxy Statement is furnished in connection with the
solicitation of proxies by the Board of Trustees of the Trust to be used in
connection with the Meeting to be held on Friday, March 15, 1996.
    
 
The management knows of no business which will be presented for consideration
other than that mentioned in Issues 1, 2 and 3 of the Notice of Annual Meeting
of Shareholders. If any other matters are properly presented at the Meeting or
any adjournment(s) thereof, it is the intention of the persons named therein to
vote the proxies in accordance with their judgment on such matters.
 
   
The Board of Trustees has fixed the close of business on January 22, 1996, as
the record date for the determination of shareholders entitled to notice of and
to vote at the Meeting (the "Record Date"). On the Record Date there were
18,026,288 shares of beneficial interest, without par value ("Shares"), of the
Trust outstanding and entitled to vote. Each of the Shares is entitled to one
vote. Shareholders of fractional Shares will be entitled to a vote of such
fraction. Shareholders holding a majority of the Shares of the Trust entitled to
vote at the Meeting will be deemed to constitute a quorum for the transaction of
business at the Meeting.
    
 
The expenses for preparation, printing and mailing of the enclosed proxy,
accompanying notice and Combined Prospectus/Proxy Statement, or any
re-solicitation of the foregoing, will be paid in part by the Trust and in part
by The Ohio Company.
 
Only shareholders of record at the close of business on the Record Date will be
entitled to notice of and to vote at the Meeting. Shares represented by
management proxies, unless previously revoked, will be voted at the Meeting in
accordance with the instructions of the shareholders. If no instructions are
given, the proxies will be voted in favor of the proposals. To revoke a
management proxy, the shareholder giving such proxy must either submit to the
Trust a subsequently dated proxy, deliver to the Trust a written notice of
revocation or otherwise give notice of revocation in open meeting, in all cases
prior to the exercise of the authority granted in the management proxy.
 
In the event that sufficient votes are not received by the Meeting date, a
person named as proxy may propose one or more adjournments of the Meeting for a
period or periods of not more than 45 days in the aggregate to permit further
solicitation of proxies. Any such adjournment will require the affirmative vote
of the holders of a majority of the Trust's shares present at the Meeting in
person or by proxy. The persons named as proxies will vote in favor of such
adjournment those proxies which they are entitled to vote in favor of the
proposals and will vote against any such adjournment those proxies required to
be voted against the proposals.
 
   
The mailing address of the principal executive offices of the Trust is 155 East
Broad Street, Columbus, Ohio 43215. The approximate date on which this Combined
Prospectus/Proxy Statement and form of proxy are first sent to shareholders is
on or about January 31, 1996.
    
 
   
As of the Record Date, the Acquiring Fund had no shares outstanding. The
Acquiring Fund does not have and will not have immediately prior to the
effective date of the Reorganization, any assets or liabilities nor will it have
commenced operations.
    
 
Any proxy which is properly executed and received in time to be voted at the
Meeting will be counted in determining whether a quorum is present and will be
voted in accordance with the instructions marked thereon. Abstentions and
"broker non-votes" (i.e., proxies from brokers or nominees indicating that such
persons have not received instructions from the beneficial owners or other
persons entitled to vote shares as to a particular matter with respect to which
the brokers or nominees do not have discretionary power to vote) will be counted
for purposes of determining whether a quorum is present. For purposes of
determining whether a proposal has been approved, abstentions and broker
non-votes will have the effect of a vote against the proposal in those instances
where the 1940 Act requires a certain percentage of all votes outstanding or of
the votes constituting
 
                                        1
<PAGE>   51
 
the quorum, but are not treated as either "against votes" or "for votes" in any
other matter except as otherwise provided by law.
 
   
                        APPROVAL OF THE PLAN -- ISSUE 1
    
 
SUMMARY
 
   
This Summary is qualified in its entirety by reference to the additional
information contained elsewhere in this Prospectus/Proxy Statement, the Plan, a
copy of which is attached to this Prospectus/Proxy Statement as Exhibit A, the
accompanying Prospectus of the Acquiring Fund dated January 10, 1996, and the
Prospectus of the Trust dated January 19, 1996.
    
 
   
PROPOSED REORGANIZATION.  The Plan provides for the transfer of all of the
assets of the Trust to the Acquiring Fund in exchange for shares of the
Acquiring Fund and the assumption by the Group on behalf of the Acquiring Fund
of all of the liabilities of the Trust. The Plan also calls for the distribution
of shares of the Acquiring Fund to the Trust's shareholders in complete
liquidation of the Trust. (The foregoing proposed transactions are referred to
in this Prospectus/Proxy Statement as the "Reorganization.") As a result of the
Reorganization, each shareholder of the Trust will become the owner of that
number of full and fractional shares of the Acquiring Fund having an aggregate
value equal to the aggregate value of the shareholder's Shares of the Trust as
of the close of business on the day preceding the date that the Trust's assets
are exchanged for shares of the Acquiring Fund. Proposals for similar
reorganizations with and into other series of the Group are simultaneously being
made to shareholders of The Cardinal Fund Inc., Cardinal Government Securities
Trust and Cardinal Tax Exempt Money Trust, the other funds of the Cardinal
family of funds.
    
 
   
For the reasons set forth below under "THE PROPOSED TRANSACTION -- REASONS FOR
THE REORGANIZATION," the Board of Trustees of the Trust, including the Trustees
of the Trust (the "Independent Trustees") who are not "interested persons" as
that term is defined in the Investment Company Act of 1940, as amended (the
"1940 Act"), at a special meeting held on November 13, 1995, unanimously
concluded that the Reorganization will be in the best interests of the Trust and
its shareholders and that the interests of the Trust's existing shareholders
will not be diluted as a result of the transaction contemplated by the
Reorganization and therefore has submitted the Plan for approval by the Trust's
shareholders. The Board of Trustees of the Group has reached similar conclusions
with respect to the Acquiring Fund and has also approved the Reorganization in
respect of the Acquiring Fund.
    
 
Approval of the Reorganization will require the affirmative vote of the lesser
of (a) 67% or more of the Shares of the Trust outstanding and represented or
present at the Meeting and (b) more than 50% of the total outstanding Shares of
the Trust. See "APPROVAL AND CONSUMMATION OF THE PROPOSED TRANSACTION" below.
 
COMPARATIVE EXPENSE INFORMATION.  The purpose of the following tables is to
assist shareholders of the Trust in understanding the costs and expenses that a
shareholder in the Acquiring Fund would bear directly or indirectly. The
shareholder transaction expenses for the Acquiring Fund are estimated for the
fiscal period following the Reorganization and ending September 30, 1996, and
reflect the proposed Rule 12b-1 fee waiver. The expenses of the Trust are based
upon the fiscal year ended September 30, 1995.

(1) The Ohio Company has agreed with the Group to waive all of its Rule 12b-1
    fees for the period following the Reorganization and ending September 30,
    1996. Absent such fee waiver, 12b-1 Fees and Total Fund Operating Expenses
    for the Acquiring Fund are estimated to be 0.25% and 0.99%, respectively.
    
 
   
(2) "Other Expenses" are based upon estimated amounts for the current fiscal
    year.

 *  These calculations reflect the expense information for the Acquiring Fund
    after giving effect to the Reorganization.
 
   
(1) Absent The Ohio Company's Rule 12b-1 fee waiver described above, expenses
    for the Acquiring Fund would be $55 and $75 for One Year and Three Years,
    respectively, and expenses for the Acquiring Fund on a pro forma basis would
    be $55, $75, $97, and $161 for One Year, Three Years, Five Years and Ten
    Years, respectively.
    
 
   
FEDERAL INCOME TAX CONSEQUENCES.  Prior to completion of the Reorganization, the
Trust will have received an opinion of counsel that, upon the consummation of
the Reorganization, no gain or loss will be recognized by the Trust or its
shareholders for federal income tax purposes. The holding period and aggregate
tax basis for the Acquiring Fund shares that are received by a Trust shareholder
will be the same as the holding period and aggregate tax basis of the Shares of
the Trust previously held by such shareholder. In addition, the holding period
and tax basis of the assets of the Trust in the hands of the Acquiring Fund as a
result of the Reorganization will be the same as the holding period and tax
basis of the assets in the hands of the Trust immediately prior to the
Reorganization.
    
 
   
APPROVAL AND CONSUMMATION OF THE PROPOSED TRANSACTION.  The Board of Trustees of
the Trust, at a special meeting held on November 13, 1995, determined
unanimously that the Reorganization is in the best interests of the Trust and
that the interests of the existing shareholders of the Trust will not be diluted
as a result of the Reorganization. Similarly, the Board of Trustees of the Group
unanimously determined that the Reorganization is in the best interests of the
Group and the Acquiring Fund. The proposed Reorganization of the Trust with and
into the Acquiring Fund is part of a larger plan to reorganize each of the
Trust, Cardinal Tax Exempt Money Trust, Cardinal Government Securities Trust and
The Cardinal Fund Inc., each a separate stand-alone investment company, with and
into a separate portfolio of the Group, and will allow the shareholders of the
Trust to realize certain
     
                                        3
<PAGE>   53
 
economies of scale as a result of becoming shareholders of a series investment
company and thus having certain fixed fees spread over a larger pool of assets.
In addition, the corporate structure of and the more uniform investment policies
and restrictions of the Acquiring Fund will improve oversight of compliance
obligations and overall management of the shareholders' investment since many of
such policies and restrictions will be the same for all of the series or
portfolios of the Group. The Acquiring Fund also is subject to the Rule 12b-1
Plan of the Group and therefore pays a 25 basis point (0.25%) fee on its average
net assets which the Trust does not pay. The Trustees of the Trust and the
Group, in approving the Reorganization, concluded that the payment of such Rule
12b-1 fees will improve the servicing of shareholder accounts by broker-dealers
and is necessary to compete successfully through a broker-dealer distribution
channel in today's marketplace when competing funds pay a similar or higher fee
to such brokers. As a result, the Boards of the Trust and the Group found that
the payment of such Rule 12b-1 fee will promote fund sales and discourage fund
redemptions and that a larger fund will be able to spread its fixed costs over a
wider base and to achieve better portfolio diversification. See "THE PROPOSED
TRANSACTION -- REASONS FOR THE PROPOSED TRANSACTION."
 
To be approved, the Plan will require the affirmative vote of the lesser of (a)
67% or more of the Shares of the Trust outstanding and represented or present at
the Meeting and (b) more than 50% of the total outstanding Shares of the Trust.
The Reorganization with respect to the Trust is not contingent on the approval
of the Reorganization with respect to any of the other Cardinal funds. If the
Trust's shareholders do not approve the proposed Reorganization, the Trust's
Board of Trustees will consider what other alternatives would be in the
shareholders' best interests. If the Plan is approved at the Meeting, the
effective date of the Reorganization (the "Closing Date") is expected to be on
or about March 31, 1996, subject, however, to the receipt by the Trust and the
Group, if necessary, of an order of exemption from the Commission with respect
to the Reorganization.
 
   
INVESTMENT OBJECTIVES AND POLICIES.  The Trust and the Acquiring Fund have the
same investment objectives, and generally have the same investment policies and
restrictions. Each of the Trust and the Acquiring Fund seek to maximize safety
of capital and, consistent with such objective, earn the highest available
current income obtainable from government securities. In order to achieve these
objectives, under normal market conditions, each 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"). Each of the Trust and the Acquiring Fund may
also invest, under normal market conditions, in certain fixed income instruments
and in repurchase agreements, and may also engage in the options transactions.
The Acquiring Fund, unlike the Trust, may also engage in futures transactions.
For a discussion of the differences between the investment policies and
restrictions of the Acquiring Fund and the Trust, see "COMPARISON OF INVESTMENT
OBJECTIVES, POLICIES AND RESTRICTIONS -- INVESTMENT RESTRICTIONS."
    
 
   
FEES AND EXPENSES.  Each of the Trust and the Acquiring Fund pay the following
fees: to Cardinal Management Corp. ("CMC") an investment advisory and management
fee computed daily and payable monthly at the annual rate of 0.50% of the value
of its average daily net assets; and to CMC for transfer agency services an
annual fee, paid monthly, at an annual rate of $21 per shareholder account plus
out-of-pocket expenses.
    
 
   
The Trust pays to CMC for fund accounting services a fee equal to $12,800 on net
assets of up to $30 million, $25,000 for the next $20 million of net assets,
$30,000 for the next $25 million of net assets, $35,000 for the next $50 million
of net assets and $5,000 for each $50 million of net assets thereafter. The
Acquiring Fund also pays to CMC for fund accounting services a fee computed
daily and paid periodically at an annual rate of .03% of its average daily net
assets of $100 million or less and .01% of its average daily net assets in
excess of $100 million.
    
 
   
Shares of each of the Trust and the Acquiring Fund are distributed by The Ohio
Company, a registered broker-dealer and the sole shareholder of CMC. The Trust
pays no distribution fees or expenses. The Acquiring Fund, however, has adopted
a distribution plan (the "Rule 12b-1 Plan") pursuant to Rule 12b-1 of the 1940
Act which permits the Acquiring Fund to pay The Ohio Company, as the
    
 
                                        4
<PAGE>   54
 
Acquiring Fund's distributor, an amount paid periodically and calculated at an
annual rate not to exceed 0.25% of the average daily net asset value of the
Acquiring Fund. Such amount may be used by The Ohio Company to pay
broker-dealers, 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. Under the
Plan, a Participating Organization may include The Ohio Company, its
subsidiaries and affiliates.
 
A sales charge is imposed upon the sale of both the Trust's and the Acquiring
Fund's shares equal to 4.5% of the public offering price (4.71% of the net
amount invested). Such sales charge is reduced on investments of $100,000 or
more, as set forth in the following table:

</TABLE>
 
For each of the Trust and the Acquiring Fund, the sales charge may be waived
under certain specified conditions.
 
The expense ratio of the Acquiring Fund subsequent to the Reorganization is
expected to be higher than that of the Trust, not taking into account the 12b-1
fee waiver by The Ohio Company. See "THE PROPOSED TRANSACTION -- REASONS FOR THE
PROPOSED TRANSACTION." The annual total operating expenses of the Trust as of
September 30, 1995, were 0.74% as a percentage of average net assets. Assuming
the same level of net assets for the Acquiring Fund after the Reorganization, it
is estimated that the total annual operating expenses for the Acquiring Fund
stated as a percentage of average net assets would be 0.74%, taking into account
the proposed Rule 12b-1 fee waiver, and 0.99%, assuming no Rule 12b-1 fee
waiver.
 
COMPARISON OF PURCHASE AND REDEMPTION PROCEDURES.  Shares of the Trust and the
Acquiring Fund are offered at net asset value, plus the applicable sales charge
as described above, and may be purchased through The Ohio Company on each
Business Day. A "Business Day" is defined as each business day the New York
Stock Exchange is open for business and on any other day (other than a day on
which no shares of that fund are tendered for redemption and no order to
purchase any shares of that fund are received) where there is sufficient trading
in such fund's portfolio securities that its net asset value per share might be
materially affected by changes in the value of its portfolio securities. The
minimum initial investment in both the Trust and the Acquiring Fund is $1,000,
the minimum subsequent investment is $50 and there is no sales charge imposed
upon the reinvestment of dividends and distributions.
 
Redemption orders for shares of both the Trust and the Acquiring Fund must be
placed with CMC. Investors may redeem Shares of the Trust at the net asset value
per share next determined following the receipt by CMC of the following: (a)
written or telephonic notice to redeem, and (b) for Shares represented by
certificates, either the share certificates, properly endorsed, or properly
executed stock powers. Investors may redeem shares of the Acquiring Fund at the
net asset value per share next determined following the receipt by CMC of
written or telephonic notice to redeem.
 
COMPARISON OF EXCHANGE PRIVILEGES.  Shares of the Trust and of the Acquiring
Fund may be exchanged for shares of any other fund advised by The Ohio Company
or CMC (a "Cardinal Fund") at respective net asset values, although payment of a
sales charge equal to the difference, if any, between the sales charge payable
upon purchase of shares of such fund and the sales charge
 
                                        5
<PAGE>   55
 
previously paid on the shares to be exchanged may be applicable upon exchanges
of shares for a Cardinal Fund sold with a sales charge.
 
COMPARISON OF DIVIDEND POLICIES.  Each of the Trust and the Acquiring Fund
declare dividends daily and pay dividends from net investment income monthly.
Each of the Trust and Acquiring Fund will distribute all of any capital gains at
least annually. In addition, shareholders of the Trust and the Acquiring Fund
receive dividends and distributions in the form of additional shares and not in
cash unless otherwise requested by the shareholder and such dividends and
distributions are of $10 or more each.
 
COMPARISON OF VOTING RIGHTS.  Each shareholder of the Trust is entitled to one
vote for each full share held and a proportionate fractional vote for each
fractional share held on each matter submitted to the vote of the Trust's
shareholders, regardless of the net asset value of such share. Each shareholder
of the Acquiring Fund, however, is entitled to one vote for each dollar of value
invested and a proportionate fractional vote for any fraction of a dollar
invested. Therefore, the number of full and fractional votes per share of the
Acquiring Fund will change depending upon the net asset value of the Acquiring
Fund's shares.
 
SPECIAL CONSIDERATIONS AND RISK FACTORS
 
Because the investment objectives, policies, strategies and restrictions of the
Trust and the Acquiring Fund are substantially similar, the overall level of
investment risk should not materially change as a result of the Reorganization.
There can be no assurance that either the Trust or the Acquiring Fund will
achieve its investment objectives. The current income earned from such
government securities as are purchased by the Trust and the Acquiring Fund may
not be as great as the current income earned on lower quality securities which
have less liquidity and greater risk of nonpayment.
 
The following discussion is qualified in its entirety by the disclosure set
forth in the Acquiring Fund's Prospectus accompanying this Combined
Prospectus/Proxy Statement and the Trust's Prospectus. For additional
information, see "COMPARISON OF INVESTMENT OBJECTIVES, POLICIES AND
RESTRICTIONS" and "ADDITIONAL COMPARATIVE INFORMATION" below.
 
MORTGAGE RELATED SECURITIES.  The Trust and the Acquiring Fund each invests or
intends to invest substantially all, but in no event less than 65% of their
assets in U.S. Government Securities. Such U.S. Government Securities 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. Each of the Trust and the
Acquiring 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
 
                                        6
<PAGE>   56
 
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 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 Trust's and
the Acquiring Fund's weighted average portfolio maturity, the effective maturity
of such securities will be used.
 
Under present market conditions, each of the Trust and the Acquiring 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 in the discretion of CMC. 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. 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.
 
WHEN-ISSUED AND DELAYED-DELIVERY TRANSACTIONS.  The Acquiring Fund may also
purchase securities on a when-issued or delayed-delivery basis. The Acquiring
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. Such securities
are not paid for or start earning interest until they are received although the
payment obligation and the coupon rate have been established before the time the
mutual fund enters into the commitment. When the Acquiring 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 mutual fund relies on the
seller to complete the transaction; the seller's failure to do so may cause such
fund to miss a price or yield considered to be advantageous.
 
The Acquiring 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 Acquiring Fund's liquidity and the ability
of CMC to manage it might be adversely affected.
 
                                        7
<PAGE>   57
 
REPURCHASE AGREEMENTS.  Securities held by each of the Trust and the Acquiring
Fund may be subject to repurchase agreements. Under the terms of a repurchase
agreement, the Trust or the Acquiring Fund acquires 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 respective Board of Trustees. At the time of
purchase, the bank or securities dealer agrees to repurchase the underlying
securities 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. Under the 1940 Act,
repurchase agreements are considered to be loans by the Trust and the Acquiring
Fund. The Trust and the Acquiring 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 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. CMC, as investment adviser, will be responsible for continuously
monitoring such requirements. In the event of a bankruptcy or other default of a
seller of a repurchase agreement, the Trust or the Acquiring Fund (as the case
may be) 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 seeking 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.
 
PUT AND CALL OPTIONS.  Subject to its investment policies and for purposes of
hedging against market risks related to its portfolio securities, unlike the
Trust, the Acquiring 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 Acquiring Fund will purchase put options only on securities in
which it may otherwise invest.
 
However, each of the Trust and the Acquiring Fund may engage in writing call
options from time to time as CMC deems appropriate. The Trust and the Acquiring
Fund will write only covered call options (options on securities owned by such
fund). The Trust and the Acquiring Fund may use covered call option strategies
as a means of increasing the total return on the portfolio and also as a means
of providing limited protection against decreases in market value. In order to
close out a call option it has written, the Trust or the Acquiring Fund, as the
case may be, 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 such fund previously has written. When a portfolio
security subject to a call option is sold, the Trust or the Acquiring Fund, as
the case may be, 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 Acquiring Fund. With respect to the Trust, it will not invest more than
5% of its total assets at any one time in premiums paid for call options and put
options.
 
The Acquiring 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 Acquiring Fund will write only covered index call options.
Through the writing or purchase of index options the Acquiring 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 Acquiring Fund owns or intends to
purchase probably will not correlate perfectly with movements in the level of an
index and, therefore, such fund bears the
 
                                        8
<PAGE>   58
 
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 Acquiring 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 Acquiring Fund, unlike the Trust, 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. Each of the Trust and the
Acquiring Fund may 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 Acquiring 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 Acquiring 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 Acquiring Fund, through the purchase of such
contracts, can attempt to secure better rates or prices for the Acquiring 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 Trust and the Acquiring 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 either the Trust's or the
Acquiring 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 such fund's total assets. Futures transactions
will be limited to the extent necessary to maintain the Trust's and the
Acquiring 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 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.
 
Options and futures 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. Neither the Trust nor the Acquiring Fund will invest more than 5%
of its total assets at any one time in premiums paid for call options and put
options or in futures contracts.
 
INVESTMENT COMPANY SECURITIES.  Each of the Trust and the Acquiring 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.
Such funds intend to invest in the securities of other money market mutual funds
for purposes of short-term cash management. Their investment in such other
investment companies may result in the duplication of fees and expenses,
particularly investment advisory fees.

THE PROPOSED TRANSACTION
 
AGREEMENT AND PLAN OF REORGANIZATION AND LIQUIDATION.  The Plan provides that
all of the assets of the Trust as of the Exchange Date (as defined in the Plan)
will be transferred to the Acquiring Fund in exchange for shares of the
Acquiring Fund and the assumption by the Acquiring Fund of all of the
liabilities of the Trust. The Exchange Date is expected to be on or about March
31, 1996, subject, however, to the receipt by the Trust and the Group of any
necessary order of exemption from the Commission with respect to the
Reorganization. A copy of the Plan is attached as Exhibit A to this Combined
Prospectus/Proxy Statement. Although portions of the Plan are summarized below,
this summary is qualified in its entirety by reference to the Plan.
 
Promptly after the Exchange Date, the Trust will distribute the shares of the
Acquiring Fund to the Trust's shareholders of record as of the close of business
on the Exchange Date. The shares of the Acquiring Fund which will be issued for
distribution to the Trust's shareholders will be equal in aggregate value to the
Shares of the Trust held as of the Valuation Time (as defined in the Plan). All
issued and outstanding Shares of the Trust will be cancelled on the Trust's
books. Shares of the Acquiring Fund will be represented only by book entries; no
share certificates will be issued.
 
The consummation of the Reorganization is subject to the satisfaction of a
number of conditions set forth in the Plan, including approval by shareholders
of the Trust. The Plan also may be terminated and the Reorganization abandoned
by the Trust and the Acquiring Fund by mutual consent of their respective
trustees. If the consummation of the Reorganization is so abandoned, no party
shall be liable to the other party for any damages resulting therefrom. If the
Reorganization is otherwise not consummated by reason of either party's being
unwilling or unable to go forward (other than by reason of the non-fulfillment
or failure of certain conditions to such party's obligations), such party will
pay directly all reasonable fees and expenses incurred by the other party in
connection with the Reorganization.
 
The Reorganization also is subject to the condition of obtaining an opinion of
counsel to the effect that the Reorganization constitutes a tax-free
reorganization for federal income tax purposes and any necessary written order
of exemption from the Commission exempting the Reorganization from the
provisions of Section 17(a) of the 1940 Act.
 
Except as otherwise provided below, all fees and expenses incurred by a party in
connection with the Plan will be paid by the party directly incurring such costs
except where a party is unwilling or unable to go forward (other than for lack
of requisite shareholder approval or breach by the other party in its covenants)
in which case such party will pay all reasonable fees and expenses of the other
party. The Ohio Company will pay the costs associated with the Reorganization.
The Trust will pay those costs associated with that portion of the Meeting
relating to customary annual meeting matters (e.g., election of trustees), and
the Acquiring Fund will bear its organizational costs.
 
Shareholders of the Trust will have no dissenters' rights or appraisal rights.
If the Plan is duly approved by shareholders, all shareholders of the Trust as
of the Exchange Date, including those that voted against the approval of the
Plan, will receive shares of the Acquiring Fund. All shareholders of the Trust
have the right at any time up to the next business day preceding the Exchange
Date to redeem their Shares at net asset value according to the procedures set
forth in the Trust's Prospectus.
 
This summary does not purport to be a complete description of the Plan and is
subject to the terms and conditions of the Plan set forth in Exhibit A.
 
REASONS FOR THE PROPOSED TRANSACTION.  Currently, the Trust is a separate,
stand-alone investment company organized in 1985. The Group was organized as a
series investment company in 1993, and in October and November 1995, its Board
of Trustees created the Acquiring Fund with substantially identical investment
objectives, policies and restrictions to those of the Trust. Because of the
similarity between the Trust and the Acquiring Fund, the considerations and
risks involved with an investment in the Acquiring Fund are expected to be
comparable to those associated with an investment in the
 
                                       10
<PAGE>   60
 
Trust. The Acquiring Fund has been established for purposes of effecting the
Reorganization and will not commence operations prior to the Exchange Date.
 
The transactions contemplated by the Plan were presented to the Board of
Trustees of the Trust for their consideration at meetings held on October 20,
1995, and November 13, 1995. The Board of Trustees of the Trust concluded
unanimously that the Reorganization is in the best interests of the Trust and
that the interests of the existing shareholders of the Trust will not be diluted
by the Reorganization.
 
The Board of Trustees of the Trust, in reaching this conclusion, considered the
costs resulting from the separate operation of the Trust and the proposed costs
of the Acquiring Fund as provided by The Ohio Company, in light of their
substantially similar investment objectives, policies, restrictions, Boards of
Trustees, officers and service providers. The Board also considered the
operating and compliance efficiencies that could result from moving the
operation of the Trust from a stand-alone investment company to a separate
portfolio of a series investment company. The investment policies and
restrictions of the Acquiring Fund which were approved by the Board of Trustees
of the Group vary somewhat from the policies of the Trust; however, such
differences reflect a more uniform and flexible set of investment restrictions
that are currently in place for each of the other series or portfolios of the
Group. Such restrictions were approved to help achieve greater compliance
efficiencies by having each series of the Group have the same or substantially
the same investment restrictions.
 
One of the operating efficiencies expected is that under Ohio law and the
Group's Declaration of Trust an annual meeting of shareholders is not required.
The Trust under its Declaration of Trust is required to hold such a meeting.
Also, certain fixed costs associated with the operation of the Trust when
incurred by the Acquiring Fund as part of the Group would decrease on a per
share basis since such costs would be spread over a larger pool of assets, e.g.,
certain legal and printing fees, while maintaining the same services by the same
service providers.
 
In particular, the Board considered the anticipated expense ratios of the
Acquiring Fund, the structure of the Group, the experience of the service
providers of the Acquiring Fund and the level of service to be provided to the
shareholders of the Acquiring Fund, as represented by The Ohio Company,
including the greater resources that could be dedicated to marketing the
Acquiring Fund and providing shareholder services.
 
The Trust's Board also considered the higher fees charged to the Acquiring Fund
compared to those of the Trust. With respect to the Rule 12b-1 fee, the Trustees
of the Trust concluded that the payment of such fees will improve the servicing
of shareholder accounts by broker-dealers and is necessary to compete
successfully through a broker-dealer distribution channel in today's marketplace
when competing funds pay a similar or higher fee to such brokers. Thus, the
Trust's Board determined that the payment of such Rule 12b-1 fees will promote
fund sales and discourage fund redemptions and that a larger fund will be able
to spread its fixed costs (exclusive of those costs based upon a percentage of
net assets) over a wider base and to achieve better portfolio diversification.
 
The Board of Trustees of the Trust based its decision to approve the proposed
transaction upon its consideration of a number of factors, including, among
other things:
 
(1) the terms and conditions of the Reorganization and whether it would result
in a dilution of the existing shareholders' interests;
 
(2) the similarity of the Trust's investment objectives, strategies and policies
with those of the Acquiring Fund, as well as the views of CMC that any
differences between the investment policies and restrictions of the Trust and
the Acquiring Fund should not materially increase investment risks;
 
(3) the experience and resources of CMC with respect to providing investment
management services, and the experience of and quality of services to be
provided by the Acquiring Fund's other service providers;
 
                                       11
<PAGE>   61
 
(4) the projected expense ratios and information regarding fees and expenses of
the Trust, the Acquiring Fund and other similar funds and the services being
offered to shareholders;
 
(5) the conditioning of the Reorganization on the receipt of a legal opinion
confirming the absence of any adverse federal tax consequences to the Trust or
its shareholders resulting from the Reorganization; and
 
(6) other factors as it deemed relevant.
 
In particular, the Board considered the following per share operating expense
ratios (total annual operating expenses expressed as a percentage of average net
assets) for shares of the Trust for the year ended September 30, 1995, and as
estimated for the shares of the Acquiring Fund for the period following the
effective date of the Reorganization and ending September 30, 1996, after giving
effect to the Reorganization:

DESCRIPTION OF THE SECURITIES TO BE ISSUED.  Ownership in the Acquiring Fund is
represented by units of beneficial interest, without par value, of The Cardinal
Group (the "Group"), which is an open-end investment company of the management
type, organized as an Ohio business trust on March 23, 1993. The Acquiring Fund
is currently one of six separate series of the Group. Like the Trust, the
Acquiring Fund is diversified, as that term is defined in the 1940 Act.
Currently there is only one class of shares for the Acquiring Fund. Shareholders
of the Acquiring Fund are entitled to one vote for each dollar of value invested
and a proportionate fractional vote for any fraction of a dollar invested. See
"ADDITIONAL COMPARATIVE INFORMATION."
 
FEDERAL INCOME TAX CONSEQUENCES.  As a condition to the closing of the
Reorganization, the Trust and the Group must receive a favorable opinion from
Baker & Hostetler, counsel to both the Trust and the Group, substantially to the
effect that, for federal income tax purposes: (a) the Reorganization will
constitute a "tax-free" reorganization within the meaning of Section 368(a) of
the Internal Revenue Code of 1986, as amended (the "Code"); (b) no gain or loss
will be recognized by the Acquiring Fund or the Trust as a result of the
Reorganization; (c) no gain or loss will be recognized by shareholders of the
Trust upon the exchange of their Shares of the Trust for shares of the Acquiring
Fund; (d) the tax basis of the Acquiring Fund shares received by shareholders of
the Trust pursuant to the Reorganization will be the same as the basis of the
Shares of the Trust held immediately prior to the Reorganization; (e) the
holding period of the Acquiring Fund shares so received will include the period
during which the Trust shareholder held Shares of the Trust, provided such
Shares were held as a capital asset; (f) the tax basis of the Trust's assets
acquired by the Acquiring Fund will be the same as the basis of such assets
immediately prior to the Reorganization; and (g) the holding period of such
assets will include the period during which those assets were held by the Trust.
The Group and the Trust do not intend to seek a private letter ruling with
respect to the tax effects of the Reorganization.
 
   
CAPITALIZATION.  The following table shows the capitalization of the Trust as of
September 30, 1995. The Acquiring Fund has no and will have no assets or
liabilities or commence operations immediately prior to the consummation of the
Reorganization. THEREFORE, NO PRO FORMA FINANCIAL INFORMATION GIVING EFFECT TO
THE REORGANIZATION IS PROVIDED.

COMPARISON OF INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS
 
INVESTMENT OBJECTIVES AND POLICIES.  The investment objectives and policies of
the Trust are substantially similar to those of the Acquiring Fund. The
investment objectives of the Trust and Acquiring Fund are "fundamental," which
means that they may not be changed without the consent of a majority of such
fund's outstanding shares, as defined in the 1940 Act.
 
The investment objectives of each of the Trust and the Acquiring Fund are to
maximize safety of capital and, consistent with such objective, earn the highest
available current income obtainable from government securities.
 
Under normal market conditions, each of the Trust and the Acquiring 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"). Each of the Trust
and the Acquiring Fund may also invest, under normal market conditions, in the
fixed income instruments described below and in repurchase agreements and may
also engage in the options transactions described above under "SPECIAL
CONSIDERATIONS AND RISK FACTORS -- OPTIONS." The Acquiring Fund, however, may
purchase securities on a when-issued or delayed-delivery basis.
 
Each of the Trust and the Acquiring Fund may, for daily cash management
purposes, invest in high quality money market securities and in repurchase
agreements. In addition, each may invest, without limit, in any combination of
U.S. Government Securities, money market securities and repurchase agreements
when, in the opinion of CMC, it is determined that a temporary defensive
position is warranted based upon current market conditions. Each of the Trust
and the Acquiring Fund may also invest in securities of other investment
companies, as described more fully above under "SPECIAL CONSIDERATIONS AND RISK
FACTORS -- INVESTMENT COMPANY SECURITIES."
 
The types of U.S. Government Securities invested in by the Trust and the
Acquiring 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 Trust and the Acquiring Fund will invest in the obligations of such agencies
or instrumentalities only when CMC believes that the credit risk with respect
thereto is minimal.
 
Certain securities held by the Trust and the Acquiring Fund may have mortgage
obligations backing such securities as more fully described above under "SPECIAL
CONSIDERATIONS AND RISK FACTORS -- MORTGAGE RELATED SECURITIES." Under present
market conditions, both the Trust and the Acquiring Fund expect to invest a
substantial amount of its portfolio in Ginnie Mae certificates.

INVESTMENT RESTRICTIONS
 
The fundamental investment restrictions of the Trust and the Acquiring Fund are
substantially identical except for the following differences:
 
(1) The Trust may not concentrate more than 25% of the value of the assets of
the Trust in investments in any particular industry. The Acquiring Fund has a
similar policy except that its policy expressly includes the Commission's
position that 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. The Acquiring Fund's policy is further qualified
as follows: (a) 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 (b) utilities will be divided
according to their services; for example, gas, gas transmission, electric and
gas, electric and telephone will each be considered a separate industry.
 
(2) The Trust may not make loans although the Trust may enter into repurchase
agreements. The Acquiring Fund has a similar policy except that such policy
contains the further exceptions that the Acquiring Fund may purchase or hold
debt instruments and lend portfolio securities in accordance with its investment
objectives and policies and make time deposits with financial institutions. The
Acquiring Fund currently does not intend to engage in portfolio securities
lending.
 
(3) The Trust may not underwrite securities issued by other persons, except: to
the extent that the Trust may be deemed to be an underwriter within the meaning
of the Securities Act of 1933 in connection with the purchase of government
securities directly from the issuer in accordance with the Trust's investment
objective, program and restrictions. The Acquiring Fund has a similar policy
except that the Acquiring Fund may underwrite the securities of others to the
extent it may be deemed to be an underwriter under certain securities laws in
the disposition of "restricted securities."
 
(4) The Trust may not purchase securities on margin, except for use of
short-term credit necessary for clearance of purchases of portfolio securities.
The Acquiring Fund has a similar policy except that the Acquiring Fund may also
make margin payments as may be necessary in connection with derivative
securities transactions.
 
(5) The Trust has a policy of not purchasing or selling commodities or commodity
contracts. The Acquiring Fund has a similar policy except it may engage in such
transactions to the extent disclosed to shareholders in its current Prospectus.
 
(6) The Trust may not purchase or retain securities of any issuer if, to the
knowledge of the Trust' management, those officers and trustees of the Trust,
and of its investment adviser, who each owns beneficially more than .5% of the
outstanding securities of such issuer, together beneficially own more than 5% of
such securities. The Acquiring Fund has no such policy.
 
(7) The Trust may not invest in puts, calls, straddles, spreads, or any
combination thereof, except as follows: (a) the Trust may write covered call
options and enter into closing purchase transactions with respect to such
options so long as the securities underlying outstanding options will not at any
one time exceed 25% of the assets of the Trust, and (b) the Trust may purchase
options in interest rate futures contracts so long as not more than 5% of the
Trust's assets are at any one time invested in the premiums paid for such
options. The Acquiring Fund has no such policy.
 
(8) The Trust may not purchase or sell real estate (although it may purchase
securities secured by real estate or interests therein). The Acquiring Fund has
the same policy except that its policy further excepts investments in marketable
securities of companies engaged in real estate activities.
 
(9) The Trust may not change its classification as a "management company" under
Section 4 of the 1940 Act or change its subclassifications as an "open-end
company" or as a "diversified company" under Section 5 of the 1940 Act. The
Acquiring Fund has no such policy although the 1940 Act requires that
shareholders approve any such change by the Acquiring Fund.
 
                                       14
<PAGE>   64
 
(10) The Trust has a fundamental policy that provides that it may not (i)
purchase securities with legal or contractual restrictions on resale (restricted
securities), (ii) purchase illiquid securities, (iii) purchase securities
without readily available market quotations, or (iv) invest more than 10% of the
value of its total assets in repurchase agreements maturing in more than seven
days. The Acquiring Fund has the non-fundamental policy that it may not purchase
or otherwise acquire any securities if as a result, more than 15% of the
Acquiring Fund's net assets would be invested in securities that are illiquid.
In addition, the Acquiring Fund may not invest more than 15% of its total assets
in securities which are restricted as to disposition.
 
In addition, the Acquiring Fund has the non-fundamental investment restriction
that it may not engage in any short sales. This non-fundamental investment
restriction is substantially similar to the fundamental investment restriction
of the Trust. As discussed above, however, fundamental restrictions of a fund
may not be changed without a vote of a majority of the outstanding voting
securities of the fund; non-fundamental policies may be changed without a
shareholder vote. As a consequence, such policies could be modified, or
eliminated, by the Group with respect to the Acquiring Fund without shareholder
approval.
 
PORTFOLIO MANAGERS.  Since CMC serves as the investment adviser to both the
Trust and the Acquiring Fund, the person currently serving as portfolio manager
for the Trust intends to serve after the Reorganization as portfolio manager for
the Acquiring Fund.
 
It is not anticipated that the above-mentioned differences in investment
policies and restrictions will, individually or in the aggregate, result in an
appreciable variation between the level of investment risks associated with an
investment in the Trust. For a more complete description of the Acquiring Fund's
investment policies and restrictions, including relevant risk factors, see "WHAT
ARE THE INVESTMENT OBJECTIVES AND POLICIES OF THE FUND?" in the Acquiring Fund's
Prospectus and "INVESTMENT OBJECTIVES AND POLICIES" in the Acquiring Fund's
Statement of Additional Information. For a more complete description of the
Trust's investment policies and restrictions, including relevant risk factors,

Trust's Prospectus and "INVESTMENT OBJECTIVES AND POLICIES" in the Trust's

Pursuant to the laws of Ohio and the Trust's Declaration of Trust, the
responsibility for the management of the Trust is vested in its Board of
Trustees which, among other things, is empowered by the Trust's Declaration of
Trust to elect officers of the Trust and contract with and provide for the
compensation of agents, consultants, and other professionals to assist and

Ohio Company. CMC is also the investment adviser and manager of each of the
other Cardinal Funds except The Cardinal Fund Inc. CMC was established as an

Ohio 43215, serves as the independent accountants for the Trust, and, as such,
has audited the financial statements of the Trust.
 
   
MANAGEMENT DISCUSSION OF FUND PERFORMANCE.  When management communicated with
shareholders at the end of the Trust's 1994 fiscal year, management felt that
1995 would be a good year for the fixed-income markets as the economy was
projected to make a soft landing, and inflation would remain under control. With
that outlook, management made adjustments in the Trust's portfolio of
mortgage-backed securities by extending the average life of the portfolio which
allowed the Trust to more fully participate in the expected market rally. As
anticipated, interest rates fell sharply, and the past 12 months have indeed
been one of the best periods on record for the fixed-income markets. The Trust
participated in the market rally and produced a total return of 11.27%, while
gaining $0.22 in net asset value per share during the year that ended September
30, 1995.
    
 
                                       16
<PAGE>   66
 
   
As management looks ahead, the projections for the domestic economy remain
optimistic, but the outlook for some of the United States' major trading
partners is less than rosy. In the near term, inflation should remain under
control. Longer term, there are some troublesome signs appearing, mainly in
those sectors of the global economy where commodity prices have increased
steadily over the past few years. Additionally, there are continuing concerns
about the Japanese banking system because of the heavy concentration of
questionable real estate loans in those institutions. Management's efforts will
be directed toward maintaining a portfolio with a low level of price volatility
to assure the preservation of the Trust's capital while continuing to provide as
high a dividend payout as is possible.

                               THE ACQUIRING 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, who are elected
by the shareholders of the Group's series or portfolios, including the Acquiring
Fund, and who are empowered to elect officers and contract
 
                                       17

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.
 
INVESTMENT ADVISER.  The Acquiring Fund is also advised by CMC. It is intended
that upon completion of the Reorganization, Mr. Carle will be responsible for
the day-to-day management of the Acquiring Fund's portfolio. For its services as
investment adviser, CMC receives a fee, which is calculated daily and paid
monthly, at an annual rate of 0.50% of the average daily net assets of the
Acquiring Fund.
 
For a complete description of the Acquiring Fund's advisory arrangements, see
the section in the Acquiring Fund's Prospectus entitled "WHO MANAGES MY
INVESTMENT IN THE FUND? -- Investment Adviser and Manager."
 
DIVIDEND AND TRANSFER AGENT AND FUND ACCOUNTANT.  CMC also serves as the
Acquiring Fund's Dividend and Transfer Agent. In consideration of such services,
the Acquiring Fund has agreed to pay CMC an annual fee, paid monthly, equal to
$21 per shareholder account, plus out-of-pocket expenses.
 
In addition, CMC provides certain fund accounting services for the Acquiring
Fund. CMC receives a fee from the Acquiring Fund for such services equal to a
fee computed daily and paid periodically at an annual rate of .03% of the
Acquiring Fund's average daily net assets of $100 million or less and .01% of
its average daily net assets in excess of $100 million.
 
For a complete description of these arrangements and the other expenses borne by
the Acquiring Fund, see the sections in the Acquiring Fund's Prospectus entitled
"WHO MANAGES MY INVESTMENT IN THE FUND? -- Dividend and Transfer Agent and Fund
Accountant."
 
DISTRIBUTOR.  The Ohio Company also serves as the distributor of the Acquiring
Fund's shares pursuant to a distribution agreement.
 
   
Pursuant to Rule 12b-1 under the 1940 Act, the Group has adopted a Rule 12b-1
Plan under which the Acquiring Fund is authorized to pay The Ohio Company, as
the Acquiring Fund's principal underwriter, a periodic amount calculated at an
annual rate not to exceed .25% of the average daily net asset value of the
Acquiring Fund. Such amount may be used by The Ohio Company to pay
broker-dealers, 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's subsidiaries, and its
affiliates.
    
 
As authorized by the Plan, The Ohio Company has agreed to provide certain
shareholder services in connection with shares of the Acquiring Fund purchased
and held by The Ohio Company for the accounts of its customers and shares of the
Acquiring Fund purchased and held by customers of The Ohio Company directly,
including, but not limited to, answering shareholder questions concerning the
Acquiring Fund, providing information to shareholders on their investments in
the Acquiring 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
shares held during the period in customer accounts for which The Ohio Company
has provided services under the Plan. Such fees paid by the Group will be borne
solely by the Acquiring Fund.
 
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.
 
   
For a complete description of these arrangements, see the section in the
Acquiring Fund's Prospectus entitled "WHO MANAGES MY INVESTMENT IN THE
FUND? -- Distribution Plan."
    
 
                                       18
<PAGE>   68
 
For fiscal period ending September 30, 1996, The Ohio Company has agreed to
waive all of such 12b-1 fees.
 
CUSTODIAN.  The Acquiring Fund has also appointed Fifth Third as the Acquiring
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
Acquiring Fund.
 
COUNSEL.  Baker & Hostetler, 65 East State Street, Columbus, Ohio 43215, also
serves as counsel to the Acquiring Fund.
 
INDEPENDENT ACCOUNTANTS.  KPMG Peat Marwick LLP, Two Nationwide Plaza, Columbus,
Ohio 43215, has been selected to serve as the independent accountants for the
Acquiring Fund, and, as such, will audit the financial statements of the
Acquiring Fund.
 
MANAGEMENT DISCUSSION OF FUND PERFORMANCE.  No management discussion of fund
performance is included since the Acquiring Fund has not yet commenced
operations.
 
CERTAIN FINANCIAL INFORMATION.  The Prospectus for the Trust contains
information on per share income, capital changes and performance calculations
under the caption "FINANCIAL HIGHLIGHTS."
 
The Acquiring Fund has not yet commenced operations and has no and will have no
assets or liabilities prior to the consummation of the Reorganization.
Therefore, no information regarding per share income and capital changes is
available. For information regarding performance calculations and comparisons,
see the information under the caption "PERFORMANCE INFORMATION" in the Acquiring
Fund's Prospectus.
 
COMPARISON OF RIGHTS OF SECURITY HOLDERS.  The Trust is an Ohio business trust,
registered under the 1940 Act as an open-end investment company of the
management type. The Trust was established under a Declaration of Trust dated
November 15, 1985. The Group is an Ohio business trust, registered under the
1940 Act as an open-end investment company of the management type. The Group was
established under a Declaration of Trust dated as of March 23, 1993. Both the
Trust and the Group are authorized to issue an unlimited number of shares of
beneficial interest, and for the Group, such shares may be divided into one or
more series or separate classes of shares. The Acquiring Fund is one of six
series of the Group. The other five series of the Group are The Cardinal Fund,
Cardinal Government Securities Money Market Fund, Cardinal Tax Exempt Money
Market Fund, Cardinal Balanced Fund and Cardinal Aggressive Growth Fund.
 
Each Share of the Trust represents an equal proportionate interest in the Trust
with each other Share. Shares are entitled upon liquidation to a pro rata share
of the net assets of the Trust. Shares of the Trust issued pursuant to the
Trust's Declaration of Trust are fully paid and nonassessable and have no
preemptive or other right to subscribe for any additional Shares.
 
Shares of the Acquiring Fund, once properly issued and outstanding, are fully
paid and nonassessable and have no preference as to conversion, exchange,
dividends, retirement or other features, and have no preemptive or appraisal
rights.
 
Shareholders of the Trust are entitled to one vote for each full Share held and
a proportionate fractional vote for each fractional Share held. Shareholders of
the Acquiring Fund are entitled to one vote for each dollar of value invested
and a proportionate fractional vote for any fraction of a dollar invested.
 
   
Voting rights for Trust shareholders are not cumulative, so that the holders of
a plurality of the Shares the Trust voting in the election of its Trustees have
the power to elect all of the Trustees of the Trust. The Trust currently holds
an annual meeting of shareholders.
    
 
Shareholders of the Group have no cumulative voting rights, which means that the
holders of a plurality of the shares voting for the election of the Group's
Board of Trustees can elect all of the Group's Board of Trustees if they choose
to do so. The Group does not intend to hold annual
 
                                       19
<PAGE>   69
 
meetings of shareholders, except as required under its Declaration of Trust or
the 1940 Act. Shareholders of the Acquiring Fund will vote in the aggregate with
other shareholders of the Group and not by series or portfolio except as
otherwise expressly required by law. For example, shareholders of the Acquiring
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 Acquiring 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 Acquiring Fund's investment advisory
agreement or any of the Acquiring Fund's fundamental policies.
 
Therefore, after the Reorganization, shareholders of the Acquiring Fund alone
will not be able to elect the Trustees of the Group or ratify the selection of
independent accountants but will vote with all the other shareholders of the
Group on such issues if and when presented to shareholders. In addition, since
the Group currently does not intend to hold annual meetings unless otherwise
required to do so, it can not be determined when shareholders of the Acquiring
Fund will next be entitled to vote for the election of Trustees or the
ratification of the selection of independent public accountants.

THE TRUST'S BOARD OF TRUSTEES AND MANAGEMENT RECOMMEND APPROVAL OF THE PLAN.
 
   
                        ELECTION OF TRUSTEES -- ISSUE 2
    
 
   
It is the present intention that the enclosed proxy will be used for the
purposes of voting in favor of the election of each of the following ten
nominees as a trustee to hold office until the next annual meeting and until his
successor is elected and qualified. Each of the nominees is a member of the
present Board of Trustees of the Trust and, except for Mr. Allen, each has been
elected by shareholder vote. Pursuant to Rule 14a-4(d) under the Securities
Exchange Act of 1934, each nominee has consented to be named in this Combined
Prospectus/Proxy Statement and to serve if elected. It is not expected that any
of the nominees will decline or become unavailable for election, but in case
this should happen, the discretionary power given in the proxy may be used to
vote for a substitute nominee or nominees.

together with the costs of any supplementary solicitation and proxy soliciting
services provided by third parties, will be borne in part by the Trust and in
part by The Ohio Company. Proxies will be solicited initially, and in any
supplemental solicitation, by mail and may be solicited in person, by telephone,
telegraph or other electronic means by officers of the Trust and by third party
proxy solicitors.
    
 
   
SUBSTANTIAL SHAREHOLDERS.  As of January 22, 1996, to the knowledge of the

              AGREEMENT AND PLAN OF REORGANIZATION AND LIQUIDATION
 
Agreement and Plan of Reorganization and Liquidation ("Agreement") dated as of
December 1, 1995, by and between The Cardinal Group, an Ohio business trust
("TCG"), and Cardinal Government Obligations Fund, an Ohio business trust
("CGOF").
 
WHEREAS, TCG is registered under the Investment Company Act of 1940, as amended
("1940 Act"), as an open-end investment company of the management type and has,
or before the Exchange Date (as defined below) is expected to have, issued and
outstanding one class of shares of beneficial interest, without par value
("Shares"), for each of six series, one such series being Cardinal Government
Obligations Fund (hereinafter sometimes referred to as the "Cardinal Government
Obligations Fund" or the "Acquiring Series"); and
 
WHEREAS, CGOF is registered under the 1940 Act as an open-end investment company
of the management type and currently has issued and outstanding one class of
shares of beneficial interest, without par value; and
 
WHEREAS, CGOF plans to transfer all of its assets, and to assign all of its
liabilities, to the Acquiring Series, in exchange for Shares of the Acquiring
Series (the "Acquiring Series Shares"), followed by the distribution of the
Acquiring Series Shares by CGOF to its shareholders, and followed by the
dissolution of CGOF, all upon the terms and provisions of this Agreement (the
"Reorganization"); and
 
WHEREAS, this Agreement is intended to be and is adopted as a plan of
reorganization and liquidation within the meaning of Section 368(a) of the
United States Internal Revenue Code of 1986, as amended (the "Code"); and
 
WHEREAS, the trustees of TCG have determined that the Reorganization is in the
best interests of TCG, and that the interests of its shareholders will not be
diluted as a result thereof; and
 
WHEREAS, the trustees of CGOF have determined that the Reorganization is in the
best interests of CGOF and that the interests of its shareholders will not be
diluted as a result thereof;
 
NOW, THEREFORE, in consideration of the mutual promises herein contained, the
parties hereto covenant and agree as follows:
 
(1) PLAN OF REORGANIZATION AND LIQUIDATION.
 
(a) Sale of Assets, Assumption of Liabilities. Subject to the prior approval of
shareholders of CGOF and to the other terms and conditions contained herein
(including the obligation of CGOF to distribute to its shareholders all of its
investment company taxable income and net capital gain as described in Section
8(i) herein), CGOF agrees to sell, assign, convey, transfer and deliver to TCG
and the Acquiring Series, and TCG and the Acquiring Series agree to acquire from
CGOF on the Exchange Date (as defined below), all of the Investments (as defined
below), cash and other assets of CGOF in exchange for that number of full and
fractional Acquiring Series Shares of the Acquiring Series having an aggregate
net asset value equal to the value of all assets of CGOF transferred to the
Acquiring Series, as provided in Section 4, less the liabilities of CGOF assumed
by the Acquiring Series.
 
(b) Assets Acquired. The assets to be acquired by the Acquiring Series from CGOF
shall consist of all of CGOF's property, including, without limitation, all
Investments, cash and dividends or interest receivables which are owned by CGOF
and any deferred or prepaid expenses shown as an asset on the books of CGOF as
of the Valuation Time described in Section 4.
 
(c) Liabilities Assumed. Prior to the Exchange Date CGOF will endeavor to
discharge or cause to be discharged, or make provision for the payment of, all
of its known liabilities and obligations. The
 
                                       A-1
<PAGE>   77
 
Acquiring Series shall assume all liabilities, expenses, costs, charges and
reserves of CGOF, contingent or otherwise, including liabilities reflected in
the unaudited statement of assets and liabilities of CGOF as of the Valuation
Time, prepared by or on behalf of CGOF in accordance with generally accepted
accounting principles consistently applied from and after September 30, 1995.
 
(d) Liquidation and Dissolution. Upon consummation of the transactions described
in Section 1(a), 1(b) and 1(c) above, CGOF shall distribute in complete
liquidation to its shareholders of record as of the Exchange Date the Acquiring
Series Shares received by it, each CGOF shareholder of record being entitled to
receive that number of Acquiring Series Shares equal to the proportion which the
number of shares of beneficial interest, without par value, of CGOF held by such
shareholder bears to the total number of such shares of CGOF outstanding on such
date, and shall take such further action as may be required, necessary or
appropriate under CGOF's Declaration of Trust, Ohio law and the Code to effect
the complete liquidation and dissolution of CGOF. CGOF will fulfill all
reporting requirements under the 1940 Act, both before and after the
Reorganization.
 
(2) REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF CGOF.  CGOF represents and
warrants to and agrees with TCG and the Acquiring Series that:
 
(a) CGOF is a business trust validly existing under the laws of the State of
Ohio and has power to own all of its properties and assets and to carry out its
obligations under this Agreement. CGOF has qualified as a foreign business trust
in each jurisdiction where the ownership of its property and the conduct of its
business require qualification. CGOF has all necessary federal, state and local
authorizations to carry on its business as now being conducted and to fulfill
the terms of this Agreement, except as set forth in Section 2(l).
 
(b) CGOF is registered under the 1940 Act as an open-end investment company of
the management type, and such registration has not been revoked or rescinded and
is in full force and effect. CGOF has elected to qualify and has qualified as a
regulated investment company under Part I of Subchapter M of the Code as of and
since its first taxable year, and qualifies and intends to continue to qualify
as a regulated investment company for its taxable year ending upon its
liquidation. CGOF has been a regulated investment company under such sections of
the Code at all times since its inception.
 
(c) The statement of assets and liabilities, including the statement of
investments as of September 30, 1995, and the related statement of operations

financial position of CGOF as of such date and such statements of operations and
changes in net assets fairly reflect the results of operations and changes in
net assets for the periods covered thereby in conformity with generally accepted
accounting principles, and there are no known material liabilities of CGOF as of
such dates which are not disclosed therein.
 
(d) The Prospectus of CGOF dated February 1, 1995 (the "CGOF Prospectus") and
the related Statement of Additional Information for CGOF dated February 1, 1995,
in the forms filed with the Securities and Exchange Commission and previously
furnished to TCG, did not as of their date and do not as of the date hereof
contain any 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.
 
(e) Except as may have been previously disclosed to TCG, there are no material
legal, administrative or other proceedings pending or, to the knowledge of CGOF
threatened against CGOF.
 
(f) There are no material contracts outstanding to which CGOF is a party, other

<PAGE>   78
 
(g) CGOF has no known liabilities of a material nature, contingent or otherwise,
other than those shown as belonging to it on its statement of assets and
liabilities as of September 30, 1995 and those incurred in the ordinary course
of CGOF's business as an investment company since that date. Prior to the
Exchange Date, CGOF will advise TCG of all known material liabilities,
contingent or otherwise, incurred by it subsequent to September 30, 1995,
whether or not incurred in the ordinary course of business.
 
   
(h) As used in this Agreement, the term "Investments" shall mean CGOF's
investments shown on the statement of assets and liabilities as of September 30,
1995 referred to in Section 2(c) hereof, as supplemented with such changes as
CGOF shall make after September 30, 1995 and prior to the date of this
Agreement, which changes have been disclosed to TCG, and changes made on and
after the date of this Agreement after advising CGPF of such changes, and
changes resulting from stock dividends stock split-ups, mergers and similar
corporate actions.
    
 
(i) CGOF has filed or will file all federal and state tax returns which, to the
knowledge of CGOF's officers, are required to be filed by CGOF and has paid or
will pay all federal and state taxes shown to be due on said returns or on any
assessments received by CGOF. All tax liabilities of CGOF have been adequately
provided for on its books, and no tax deficiency or liability of CGOF has been
asserted, and no question with respect thereto has been raised, by the Internal
Revenue Service or by any state or local tax authority for taxes in excess of
those already paid.
 
   
(j) As of both the Valuation Time and the Exchange Date and except for
shareholder approval and otherwise as described in Section 2(1), CGOF will have
full right, power and authority to sell, assign, transfer and deliver the
Investments and any other of its assets and liabilities to be transferred to TCG
and the Acquiring Series pursuant to this Agreement. At the Exchange Date,
subject only to the delivery of the Investments and any such other assets and
liabilities as contemplated by this Agreement, TCG and the Acquiring Series will
acquire the Investments and any such other assets subject to no encumbrances,
liens or security interests in favor of any third party creditor of CGOF and,
except as described in Section 2(k), without any restrictions upon the transfer
thereof.
    
 
(k) No registration under the Securities Act of 1933, as amended (the "1933
Act"), of any of the Investments would be required if they were, as of the time
of such transfer, the subject of a public distribution by either of CGOF or TCG,
except as previously disclosed to TCG by CGOF in writing prior to the date
hereof.
 
(l) No consent, approval, authorization or order of any court or governmental

state securities or blue sky laws (which term as used herein shall include the
laws of the District of Columbia and of Puerto Rico) or the Hart-Scott-Rodino

the Securities and Exchange Commission (the "Commission") by TCG on Form N-14
relating to the Acquiring Series Shares issuable hereunder, and the proxy
statement of CGOF included therein (the "Proxy Statement"), on the effective
date of the Registration Statement and insofar as they relate to CGOF, (i) will
comply in all material respects with the provisions of the 1933 Act, 1934 Act
and 1940 Act and the rules and regulations thereunder and (ii) will not contain
any untrue statement of a material fact or omit to state a material fact

CGOF shareholder receives in connection with the Reorganization will be the same

such opinion, Baker & Hostetler may rely upon certain reasonable and customary
assumptions and certifications of fact received from TCG, CGOF, and certain of
its shareholders.

                                CARDINAL FUNDS

                                                                January 26, 1996
    
   
Dear Cardinal Government Securities Trust Shareholder:
    
 
   
The Board of Trustees of Cardinal Government Securities Trust (the "Trust")
recently reviewed and unanimously approved a proposal to reorganize the Trust
with and into a newly created series of The Cardinal Group (the "Group"). This
Agreement and Plan of Reorganization and Liquidation is described in the
accompanying Combined Prospectus/Proxy Statement and will be addressed at the
Annual Meeting of Shareholders on March 15, 1996.
    
 
The primary purpose of the proposed reorganization is to achieve certain
economies of scale by having the Trust become an additional series of the Group
rather than operate as a separate stand-alone investment company. By operating
more efficiently, we expect to realize cost savings through the elimination of
certain Annual Meeting expenses, a reduction of printing and mailing
expenditures, the lowering of regulatory filing expenses and the reduction of
professional fees. The Board determined that such a reorganization is in the
best interest of the Trust.
 
   
If the proposed reorganization is approved, you will receive shares of the newly
created series of the Group, known as Cardinal Government Securities Money
Market Fund, in exchange for your shares of the Trust. Shares received in this
distribution will be equal in value at the time of reorganization to your shares
in the Trust. There will be no adverse federal income tax consequences
associated with this distribution.
    
 
As a result of the reorganization, many features of the new series will be the
same as those of the Trust. For instance, the securities in the underlying
portfolio will remain the same. Purchase and redemption procedures will not
change. Slight differences in investment policies and restrictions are proposed

This Combined Prospectus/Proxy Statement is being furnished to shareholders of
Cardinal Government Securities Trust, a Pennsylvania business trust (the
"Trust"), in connection with the solicitation of proxies by the Board of
Trustees of the Trust to be used at the Annual Meeting of Shareholders of the
Trust (the "Meeting"), to be held at The Athletic Club of Columbus, 136 East
Broad Street, Columbus, Ohio 43215 on Friday, March 15, 1996, beginning at 9:30
A.M. (Eastern Time).
    
 
In addition to the customary annual election of Trustees and ratification of the
selection of independent accountants, the Trustees of the Trust are seeking your
approval of an Agreement and Plan of Reorganization and Liquidation (the
"Plan"), which contemplates that Cardinal Government Securities Money Market
Fund (the "Acquiring Fund"), a series or portfolio of The Cardinal Group (the
"Group"), will acquire all of the assets of and will assume all of the
liabilities of the Trust in exchange for shares of the Acquiring Fund.
 
Following such exchange, the shares of the Acquiring Fund received by the Trust
will be distributed to the Trust's shareholders and the Trust will be liquidated
and dissolved. This exchange and distribution transaction is sometimes referred
to herein as the "Reorganization."
 
This Combined Prospectus/Proxy Statement, which should be retained for future
reference, sets forth concisely the information about the Acquiring Fund that a
prospective investor, including shareholders of the Trust, should know before
investing. Additional information about the Reorganization and the Acquiring
Fund is contained in a separate Statement of Additional Information which has
been filed with the Securities and Exchange Commission (the "Commission") and is
available upon request without charge by calling the Group at (800) 282-9446 or
writing to the Group at the address set forth above. The Statement of Additional
Information bears the same date as this Combined Prospectus/Proxy Statement and
is incorporated by reference herein.
 
THE SHARES OF THE ACQUIRING 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 ACQUIRING FUND
INVOLVES CERTAIN INVESTMENT RISKS, INCLUDING THE POSSIBLE LOSS OF PRINCIPAL. THE
ACQUIRING 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.
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
    EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
       SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
         COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS
         PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
            CRIMINAL OFFENSE.
<PAGE>   91
 
Upon completion of the Reorganization, you will receive full and fractional
shares of the Acquiring Fund equal in value when issued to the shares of the
Trust owned by you immediately prior to the Reorganization. No commissions or
sales loads will be charged in connection with the Reorganization and there will
be no adverse federal income tax consequences. You should separately consider
any other tax consequences in consultation with your tax advisers.
 
   
As discussed in detail herein, the investment objectives and strategy of the
Acquiring Fund are substantially similar to those of the Trust. There are some
differences between investment policies and restrictions, as well as differences
in fees and in voting rights, which are described in detail below. The
Prospectus of the Acquiring Fund relating to its shares, dated January 10, 1996,
is incorporated by reference in this Combined Prospectus/Proxy Statement and
accompanies this Combined Prospectus/Proxy Statement.
    
 
   
The Trust's Prospectus dated January 19, 1996, contains additional information
about the Trust, has been filed with the Commission, is incorporated by
reference herein and is available without charge by writing the Trust at 155
East Broad Street, Columbus, Ohio 43215, or by calling the Trust at (800)
282-9446. Copies of documents requested will be sent by first-class mail to the
requesting shareholder within one business day of the request.

                                    GENERAL
 
   
This Combined Prospectus/Proxy Statement is furnished in connection with the
solicitation of proxies by the Board of Trustees of the Trust to be used in
connection with the Meeting to be held on Friday, March 15, 1996.
    
 
The management knows of no business which will be presented for consideration
other than that mentioned in Issues 1, 2 and 3 of the Notice of Annual Meeting
of Shareholders. If any other matters are properly presented at the Meeting or
any adjournment(s) thereof, it is the intention of the persons named therein to
vote the proxies in accordance with their judgment on such matters.
 
   
The Board of Trustees has fixed the close of business on January 22, 1996, as
the record date for the determination of shareholders entitled to notice of and
to vote at the Meeting (the "Record Date"). On the Record Date there were
485,533,531 shares of beneficial interest, par value $0.01 per share ("Shares"),
of the Trust outstanding and entitled to vote. Each of the Shares is entitled to
one vote. Shareholders of fractional Shares will be entitled to a vote of such
fraction. Shareholders holding a majority of the outstanding Shares of the Trust
will be deemed to constitute a quorum for the transaction of business at the
Meeting.
    
 
The expenses for preparation, printing and mailing of the enclosed proxy,
accompanying notice and Combined Prospectus/Proxy Statement, or any
re-solicitation of the foregoing, will be paid in part by the Trust and in part
by The Ohio Company.
 
Only shareholders of record at the close of business on the Record Date will be
entitled to notice of and to vote at the Meeting. Shares represented by
management proxies, unless previously revoked, will be voted at the Meeting in
accordance with the instructions of the shareholders. If no instructions are
given, the proxies will be voted in favor of the proposals. To revoke a
management proxy, the shareholder giving such proxy must either submit to the
Trust a subsequently dated proxy, deliver to the Trust a written notice of
revocation or otherwise give notice of revocation in open meeting, in all cases
prior to the exercise of the authority granted in the management proxy.
 
In the event that sufficient votes are not received by the Meeting date, a
person named as proxy may propose one or more adjournments of the Meeting for a
period or periods of not more than 45 days in the aggregate to permit further
solicitation of proxies. Any such adjournment will require the affirmative vote
of the holders of a majority of the Trust's Shares present at the Meeting in
person or by proxy. The persons named as proxies will vote in favor of such
adjournment those proxies which they are entitled to vote in favor of the
proposals and will vote against any such adjournment those proxies required to
be voted against the proposals.
 
   
The mailing address of the principal executive offices of the Trust is 155 East
Broad Street, Columbus, Ohio 43215. The approximate date on which this Combined
Prospectus/Proxy Statement and form of proxy are first sent to shareholders is
on or about January 31, 1996.
    
 
   
As of the Record Date, the Acquiring Fund had no shares outstanding. The
Acquiring Fund does not have and will not have immediately prior to the
effective date of the Reorganization, any assets or liabilities nor will it have
commenced operations.
    
 
Any proxy which is properly executed and received in time to be voted at the
Meeting will be counted in determining whether a quorum is present and will be
voted in accordance with the instructions marked thereon. Abstentions and
"broker non-votes" (i.e., proxies from brokers or nominees indicating that such
persons have not received instructions from the beneficial owners or other
persons entitled to vote shares as to a particular matter with respect to which
the brokers or nominees do not have discretionary power to vote) will be counted
for purposes of determining whether a quorum is present. For purposes of
determining whether a proposal has been approved, abstentions and broker
non-votes will have the effect of a vote against the proposal in those instances
where approval of an issue requires a certain percentage of all votes
outstanding or of the votes constituting the quorum.

                        APPROVAL OF THE PLAN -- ISSUE 1
    
 
SUMMARY
 
   
This Summary is qualified in its entirety by reference to the additional
information contained elsewhere in this Prospectus/Proxy Statement, the Plan, a
copy of which is attached to this Prospectus/Proxy Statement as Exhibit A, the
accompanying Prospectus of the Acquiring Fund dated January 10, 1996, and the
Prospectus of the Trust dated January 19, 1996.
    
 
   
PROPOSED REORGANIZATION.  The Plan provides for the transfer of all of the
assets of the Trust to the Acquiring Fund in exchange for shares of the
Acquiring Fund and the assumption by the Group on behalf of the Acquiring Fund
of all of the liabilities of the Trust. The Plan also calls for the distribution
of shares of the Acquiring Fund to the Trust's shareholders in complete
liquidation of the Trust. (The foregoing proposed transactions are referred to
in this Prospectus/Proxy Statement as the "Reorganization.") As a result of the
Reorganization, each shareholder of the Trust will become the owner of that
number of full and fractional shares of the Acquiring Fund having an aggregate
value equal to the aggregate value of the shareholder's Shares of the Trust as
of the close of business on the day preceding the date that the Trust's assets
are exchanged for shares of the Acquiring Fund. Proposals for similar
reorganizations with and into other series of the Group are simultaneously being
made to shareholders of The Cardinal Fund Inc., Cardinal Government Obligations
Fund and Cardinal Tax Exempt Money Trust, the other funds of the Cardinal family
of funds.
    
 
   
For the reasons set forth below under "THE PROPOSED TRANSACTION -- REASONS FOR
THE REORGANIZATION," the Board of Trustees of the Trust, including the Trustees
of the Trust (the "Independent Trustees") who are not "interested persons" as
that term is defined in the Investment Company Act of 1940, as amended (the
"1940 Act"), at a special meeting held on November 13, 1995, unanimously
concluded that the Reorganization will be in the best interests of the Trust and
its shareholders and that the interests of the Trust's existing shareholders
will not be diluted as a result of the transaction contemplated by the
Reorganization and therefore has submitted the Plan for approval by the Trust's
shareholders. The Board of Trustees of the Group has reached similar conclusions
with respect to the Acquiring Fund and has also approved the Reorganization in
respect of the Acquiring Fund.
    
 
Approval of the Reorganization will require the affirmative vote of not less
than two-thirds of the Shares of the Trust outstanding. See "APPROVAL AND
CONSUMMATION OF THE PROPOSED TRANSACTION" below.
 
COMPARATIVE EXPENSE INFORMATION.  The purpose of the following tables is to
assist shareholders of the Trust in understanding the costs and expenses that a
shareholder in the Acquiring Fund would bear directly or indirectly. The
shareholder transaction expenses for the Acquiring Fund are estimated for the
fiscal period following the Reorganization and ending September 30, 1996. The
expenses of the Trust are based upon the fiscal year ended September 30, 1995.

FEDERAL INCOME TAX CONSEQUENCES.  Prior to completion of the Reorganization, the
Trust will have received an opinion of counsel that, upon the consummation of
the Reorganization, no gain or loss will be recognized by the Trust or its
shareholders for federal income tax purposes. The holding period and aggregate
tax basis for the Acquiring Fund shares that are received by a Trust shareholder
will be the same as the holding period and aggregate tax basis of the Shares of
the Trust previously held by such shareholder. In addition, the holding period
and tax basis of the assets of the Trust in the hands of the Acquiring Fund as a
result of the Reorganization will be the same as the holding period and tax
basis of the assets in the hands of the Trust immediately prior to the
Reorganization.
    
 
   
APPROVAL AND CONSUMMATION OF THE PROPOSED TRANSACTION.  The Board of Trustees of
the Trust, at a special meeting held on November 13, 1995, determined
unanimously that the Reorganization is in the best interests of the Trust and
that the interests of the existing shareholders of the Trust will not be diluted
as a result of the Reorganization. Similarly, the Board of Trustees of the Group
unanimously determined that the Reorganization is in the best interests of the
Group and the Acquiring Fund. The proposed Reorganization of the Trust with and
into the Acquiring Fund is part of a larger plan to reorganize each of the
Trust, Cardinal Government Obligations Fund, Cardinal Tax Exempt Money Trust and
The Cardinal Fund Inc., each a separate stand-alone investment company, with and
into a separate portfolio of the Group, and will allow the shareholders of the
Trust to realize certain economies of scale as a result of becoming shareholders
of a series investment company and thus having certain fixed fees spread over a
larger pool of assets. In addition, the corporate structure of and the more
uniform investment policies and restrictions of the Acquiring Fund will improve
oversight of compliance obligations and overall management of the shareholders'
investment since many of such policies and restrictions will be the same for all
of the series or portfolios of the Group. See "THE PROPOSED TRANSACTION --
REASONS FOR THE PROPOSED TRANSACTION."
    
 
To be approved, the Plan will require the affirmative vote of no less than
two-thirds of the Shares of the Trust entitled to vote on the matter. The
Reorganization with respect to the Trust is not contingent on the approval of
the Reorganization with respect to any of the other Cardinal funds. If the
Trust's shareholders do not approve the proposed Reorganization, the Trust's
Board of Trustees will consider what other alternatives would be in the
shareholders' best interests. If the Plan is approved at the Meeting, the
effective date of the Reorganization (the "Closing Date") is expected to be on
or about March 31, 1996, subject, however, to the receipt by the Trust and the
Group, if necessary, of an order of exemption from the Commission with respect
to the Reorganization.
 
INVESTMENT OBJECTIVES AND POLICIES.  The Trust and the Acquiring Fund have the
same investment objectives, and generally have the same investment policies and
restrictions. Each of the Trust and the Acquiring Fund seek to maximize current
income while preserving capital and maintaining liquidity. In order to achieve
these objectives, the Acquiring Fund has a policy of 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
 
                                        3
<PAGE>   97
relating to such obligations. The Trust seeks to attain its investment
objectives by investing 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. Each
of the Acquiring Fund and the Trust will purchase only obligations which have,
or are deemed to have, maturities, from the date of purchase, of thirteen months
or less. For a discussion of the differences between the investment policies and
restrictions of the Acquiring Fund and the Trust, see "COMPARISON OF INVESTMENT
OBJECTIVES, POLICIES AND RESTRICTIONS -- INVESTMENT RESTRICTIONS."
 
   
FEES AND EXPENSES.  Each of the Trust and the Acquiring Fund pay the following
fees: to Cardinal Management Corp. ("CMC") an investment advisory and management
fee computed daily and payable monthly at the annual rate of 0.50% of the value
of its average daily net assets; and to CMC for transfer agency services an
annual fee, paid monthly, at an annual rate of $21 per shareholder account plus
out-of-pocket expenses.
    
 
   
The Trust pays to CMC for fund accounting services a fee equal to $9,000 for the
first $25 million of assets and $3,000 for each additional $25 million of
assets. The Acquiring Fund also pays to CMC for fund accounting services a fee
computed daily and paid periodically at an annual rate of .03% of its average
daily net assets of $100 million or less and .01% of its average daily net
assets in excess of $100 million.
    
 
Shares of each of the Trust and the Acquiring Fund are distributed by The Ohio
Company, a registered broker-dealer and the sole shareholder of CMC. Neither the
Trust nor the Acquiring Fund pays any distribution fees or expenses nor is any
sales charge imposed upon the sale of its shares.
 
The expense ratio of the Acquiring Fund subsequent to the Reorganization is
expected to be slightly lower than that of the Trust. See "THE PROPOSED
TRANSACTION -- REASONS FOR THE PROPOSED TRANSACTION." The total annual operating
expenses of the Trust as of September 30, 1995, were 0.81% as a percentage of
average net assets. Assuming the same level of net assets for the Acquiring Fund
after the Reorganization, it is estimated that the total annual operating
expenses for the Acquiring Fund stated as a percentage of average net assets
would be 0.79%.
 
COMPARISON OF PURCHASE AND REDEMPTION PROCEDURES.  Shares of the Trust and the
Acquiring Fund are offered at net asset value and may be purchased through The
Ohio Company on each day the New York Stock Exchange is open for business (a
"Business Day"). The minimum initial investment in both the Trust and the
Acquiring Fund is $1,000, the minimum subsequent investment is $100 and there is
no sales charge imposed upon the purchase of shares or upon the reinvestment of
dividends and distributions.
 
Redemption orders for shares of both the Trust and the Acquiring Fund must be
placed with CMC. Proceeds of redemption requests received by CMC 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.
 
COMPARISON OF EXCHANGE PRIVILEGES.  Shares of the Trust and of the Acquiring
Fund may be exchanged for shares of any other fund advised by The Ohio Company
or CMC (a "Cardinal Fund") at respective net asset values, although a sales
charge may be applicable upon exchanges of shares for a Cardinal Fund sold with
a sales charge.
 
COMPARISON OF DIVIDEND POLICIES.  Each of the Trust and the Acquiring Fund
declare dividends daily and pay dividends from net investment income monthly.
Each of the Trust and Acquiring Fund will distribute all of any capital gains at
least annually. In addition, shareholders of the Trust and the Acquiring Fund
receive dividends and distributions in the form of additional shares and not in
cash unless otherwise requested by the shareholder.
 
                                        4
<PAGE>   98
 
COMPARISON OF VOTING RIGHTS.  Each shareholder of the Trust is entitled to one
vote for each full share held and a proportionate fractional vote for each
fractional share held on each matter submitted to the vote of the Trust's
shareholders. Each shareholder of the Acquiring Fund, however, is entitled to
one vote for each dollar of value invested and a proportionate fractional vote
for any fraction of a dollar invested. In addition, on certain matters, such as
the election of Trustees, the shareholders of the Acquiring Fund will need to
vote as a group with the other shareholders of the Group. Therefore,
shareholders of the Acquiring Fund may be unable to elect, based upon their
votes alone, the trustees of the Group.
 
SPECIAL CONSIDERATIONS AND RISK FACTORS
 
Because the investment objectives, policies, strategies and restrictions of the
Trust and the Acquiring Fund are substantially similar, the overall level of
investment risk should not materially change as a result of the Reorganization.
There can be no assurance that either the Trust or the Acquiring Fund will
achieve its investment objectives or be able continuously to maintain a net
asset value per share of $1.00.
 
The following discussion is qualified in its entirety by the disclosure set
forth in the Acquiring Fund's Prospectus accompanying this Combined
Prospectus/Proxy Statement and the Trust's Prospectus. For additional
information, see "COMPARISON OF INVESTMENT OBJECTIVES, POLICIES AND
RESTRICTIONS" and "ADDITIONAL COMPARATIVE INFORMATION," below.
 
GOVERNMENT SECURITIES.  The Trust intends to invest all, and the Acquiring Fund
intends to be invested as fully as possible but in no event less than 80%, of
its total assets in securities issued or guaranteed by the U.S. Government, its
agencies or instrumentalities, or repurchase agreements relating to such
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 a maturity of one year or less; Treasury
notes have maturities of one to ten years and Treasury bonds generally have
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 Trust and the Acquiring Fund each intend to invest in variable
and floating rate instruments whose market value, upon reset of the interest
rate, will approximate par value 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 Trust and the Acquiring
Fund each will invest in such securities only when it is satisfied that the
credit risk with respect to the issuer is minimal.
 
REPURCHASE AGREEMENTS.  Securities held by each of the Trust and the Acquiring
Fund may be subject to repurchase agreements. Under the terms of a repurchase
agreement, the Trust or the Acquiring
 
                                        5
<PAGE>   99
Fund acquires 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 respective
Boards of Trustees. At the time of purchase, the bank or securities dealer
agrees to repurchase the underlying securities 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. Under the 1940 Act, repurchase agreements are considered to be loans
by the Trust and the Acquiring Fund. The Trust and the Acquiring 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 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. CMC will be responsible for continuously
monitoring such requirements. In the event of a bankruptcy or other default of a
seller of a repurchase agreement, the Trust or the Acquiring Fund (as the case
may be) 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 seeking 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.

INVESTMENT COMPANY SECURITIES.  Each of the Trust and the Acquiring 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.
Such funds intend to invest in the securities of other money market mutual funds
for purposes of short-term cash management. Their investment in such other
investment companies may result in the duplication of fees and expenses,
particularly investment advisory fees.
 
THE PROPOSED TRANSACTION
 
AGREEMENT AND PLAN OF REORGANIZATION AND LIQUIDATION.  The Plan provides that
all of the assets of the Trust as of the Exchange Date (as defined in the Plan)
will be transferred to the Acquiring Fund in exchange for shares of the
Acquiring Fund and the assumption by the Acquiring Fund of all of the
liabilities of the Trust. The Exchange Date is expected to be on or about March
31, 1996, subject, however, to the receipt by the Trust and the Group of any
necessary order of exemption from the Commission with respect to the
Reorganization. A copy of the Plan is attached as Exhibit A to this Combined
Prospectus/Proxy Statement. Although portions of the Plan are summarized below,
this summary is qualified in its entirety by reference to the Plan.
 
Promptly after the Exchange Date, the Trust will distribute the shares of the
Acquiring Fund to the Trust's shareholders of record as of the close of business
on the Exchange Date. The shares of the Acquiring Fund which will be issued for
distribution to the Trust's shareholders will be equal in aggregate value to the
Shares of the Trust held as of the Valuation Time (as defined in the Plan). All
issued and outstanding Shares of the Trust will be cancelled on the Trust's
books. Shares of the Acquiring Fund will be represented only by book entries; no
share certificates will be issued.
 
The consummation of the Reorganization is subject to the satisfaction of a
number of conditions set forth in the Plan, including approval by shareholders
of the Trust. The Plan also may be terminated and the Reorganization abandoned
by the Trust and the Acquiring Fund by mutual consent of their respective
trustees. If the consummation of the Reorganization is so abandoned, no party
shall be liable to the other party for any damages resulting therefrom. If the
Reorganization is otherwise not consummated by reason of either party's being
unwilling or unable to go forward (other than by reason of the non-fulfillment
or failure of certain conditions to such party's obligations), such party will
pay directly all reasonable fees and expenses incurred by the other party in
connection with the Reorganization.

The Reorganization also is subject to the condition of obtaining an opinion of
counsel to the effect that the Reorganization constitutes a tax-free
reorganization for federal income tax purposes and any
 
                                        6
<PAGE>   100
 
necessary written order of exemption from the Commission exempting the
Reorganization from the provisions of Section 17(a) of the 1940 Act.
 
Except as otherwise provided below, all fees and expenses incurred by a party in
connection with the Plan will be paid by the party directly incurring such costs
except where a party is unwilling or unable to go forward (other than for lack
of requisite shareholder approval or breach by the other party in its covenants)
in which case such party will pay all reasonable fees and expenses of the other
party. The Ohio Company will pay the costs associated with the Reorganization.
The Trust will pay those costs associated with that portion of the Meeting
relating to customary annual meeting matters (e.g., election of trustees), and
the Acquiring Fund will bear its organizational costs.
 
Shareholders of the Trust will have no dissenters' rights or appraisal rights.
If the Plan is approved by shareholders, all shareholders of the Trust as of the
Exchange Date, including those that voted against the approval of the Plan, will
receive shares of the Acquiring Fund. All shareholders of the Trust have the
right at any time up to the next business day preceding the Exchange Date to
redeem their Shares at net asset value according to the procedures set forth in
the Trust's Prospectus.
 
This summary does not purport to be a complete description of the Plan and is
subject to the terms and conditions of the Plan set forth in Exhibit A.
 
REASONS FOR THE PROPOSED TRANSACTION.  Currently, the Trust is a separate,
stand-alone investment company organized in 1980. The Group was organized as a
series investment company in 1993, and in October and November 1995, its Board
of Trustees created the Acquiring Fund with substantially similar investment
objectives, policies and restrictions to those of the Trust. Because of the
similarity between the Trust and the Acquiring Fund, the considerations and
risks involved with an investment in the Acquiring Fund are expected to be
comparable to those associated with an investment in the Trust. The Acquiring
Fund has been established for purposes of effecting the Reorganization and will
not commence operations prior to the Exchange Date.
 
The transactions contemplated by the Plan were presented to the Board of
Trustees of the Trust for their consideration at meetings held on October 20,
1995 and November 13, 1995. The Board of Trustees of the Trust concluded
unanimously that the Reorganization is in the best interests of the Trust and
that the interests of the existing shareholders of the Trust will not be diluted
by the Reorganization.
 
The Board of Trustees of the Trust, in reaching this conclusion, considered the
costs resulting from the separate operation of the Trust and the proposed costs
of the Acquiring Fund as provided by The Ohio Company, in light of their
substantially similar investment objectives, policies, restrictions, Boards of
Trustees, officers and service providers. The Board also considered the
operating and compliance efficiencies that could result from moving the
operation of the Trust from a stand-alone investment company to a separate
portfolio of a series investment company. The investment policies and
restrictions of the Acquiring Fund which were approved by the Board of Trustees
of the Group vary somewhat from the policies and restrictions of the Trust;
however, such differences reflect a more uniform and flexible set of investment
restrictions that are currently in place for each of the other series or
portfolios of the Group. Such restrictions were approved to help achieve greater
compliance efficiencies by having each series of the Group have the same or
substantially the same investment restrictions.
 
In addition, certain operating efficiencies are expected since under Ohio law
and the Group's Declaration of Trust an annual meeting of shareholders is not
required. The Trust under its Amended Declaration of Trust is required to hold
such a meeting. Also, certain fixed costs associated with the operation of the
Trust when incurred by the Acquiring Fund as part of the Group would decrease on
a per share basis since such costs would be spread over a larger pool of assets,
e.g., certain legal and printing fees, while maintaining the same services by
the same service providers.
 
In particular, the Trust's Board considered the anticipated expense ratios of
the Acquiring Fund, the structure of the Group, the experience of the service
providers of the Acquiring Fund and the level of
 
                                        7
<PAGE>   101
 
service to be provided to the shareholders of the Acquiring Fund, as represented
by The Ohio Company.
 
The Board of Trustees of the Trust based its decision to approve the proposed
transaction upon its consideration of a number of factors, including, among
other things:
 
     (1) the terms and conditions of the Reorganization and whether it would
     result in a dilution of the existing shareholders' interests;
 
     (2) the similarity of the Trust's investment objectives, strategies and
     policies with those of the Acquiring Fund, as well as the views of CMC that
     any differences between the investment policies and restrictions of the
     Trust and the Acquiring Fund should not materially increase investment
     risks;
 
     (3) the experience and resources of CMC with respect to providing
     investment management services, and the experience of, and quality of
     services to be provided by, the Acquiring Fund's other service providers;
 
     (4) the projected expense ratios and information regarding fees and
     expenses of the Trust, the Acquiring Fund and other similar funds and the
     services being offered to shareholders;
 
     (5) the conditioning of the Reorganization on the receipt of a legal
     opinion confirming the absence of any adverse federal tax consequences to
     the Trust or its shareholders resulting from the Reorganization; and
 
     (6) other factors as it deemed relevant.
 
In particular, the Board considered the following per share operating expense
ratios (total annual operating expenses expressed as a percentage of average net
assets) for Shares of the Trust for the year ended September 30, 1995, and as
estimated for the shares of the Acquiring Fund for the period following the
effective date of the Reorganization and ending September 30, 1996, after giving
effect to the Reorganization:

DESCRIPTION OF THE SECURITIES TO BE ISSUED.  Ownership in the Acquiring Fund is
represented by units of beneficial interest, without par value, of The Cardinal
Group (the "Group"), which is an open-end investment company of the management
type, organized as an Ohio business trust on March 23, 1993. The Acquiring Fund
is currently one of six separate series of the Group. Like the Trust, the
Acquiring Fund is diversified, as that term is defined in the 1940 Act.
Currently there is only one class of shares for the Acquiring Fund. Shareholders
of the Acquiring Fund are entitled to one vote for each dollar of value invested
and a proportionate fractional vote for any fraction of a dollar invested. See
"ADDITIONAL COMPARATIVE INFORMATION."
 
FEDERAL INCOME TAX CONSEQUENCES.  As a condition to the closing of the
Reorganization, the Trust and the Group must receive a favorable opinion from
Baker & Hostetler, counsel to both the Trust and the Group, substantially to the
effect that, for federal income tax purposes: (a) the Reorganization will
constitute a "tax-free" reorganization within the meaning of Section 368(a) of
the Internal Revenue Code of 1986, as amended (the "Code"); (b) no gain or loss
will be recognized by the Acquiring Fund or the Trust as a result of the
Reorganization; (c) no gain or loss will be recognized by shareholders of the
Trust upon the exchange of their Shares of the Trust for shares of the Acquiring
Fund; (d) the tax basis of the Acquiring Fund shares received by shareholders of
the Trust pursuant to the Reorganization will be the same as the basis of the
Shares of the Trust held immediately prior to the Reorganization; (e) the
holding period of the Acquiring Fund shares so received will include the
 
                                        8
<PAGE>   102
 
period during which the Trust shareholder held Shares of the Trust, provided
such Shares were held as a capital asset; (f) the tax basis of the Trust's
assets acquired by the Acquiring Fund will be the same as the basis of such
assets immediately prior to the Reorganization; and (g) the holding period of
such assets will include the period during which those assets were held by the
Trust. The Group and the Trust do not intend to seek a private letter ruling
with respect to the tax effects of the Reorganization.
 
   
CAPITALIZATION.  The following table shows the capitalization of the Trust as of
September 30, 1995. The Acquiring Fund has no and will have no assets or
liabilities or commence operations immediately prior to the consummation of the
Reorganization. THEREFORE, NO PRO FORMA FINANCIAL INFORMATION GIVING EFFECT TO
THE REORGANIZATION IS PROVIDED.

COMPARISON OF INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS
 
INVESTMENT OBJECTIVES AND POLICIES.  The investment objectives and policies of
the Trust are substantially similar to those of the Acquiring Fund. The
investment objectives of the Trust and Acquiring Fund are "fundamental," which
means that they may not be changed without the consent of a majority of such
fund's outstanding shares, as defined in the 1940 Act.
 
The investment objectives of each of the Trust and the Acquiring Fund are to
maximize current income while preserving capital and maintaining liquidity.
 
As money market funds, each of the Trust and the Acquiring Fund invests
exclusively in United States dollar-denominated instruments which are determined
by CMC and the Trustees to 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. All
securities or instruments in which the Trust and the Acquiring Fund invest have,
or are deemed to have, remaining maturities of 397 calendar days (thirteen
months) or less. The dollar-weighted average maturity of the obligations in each
of the Trust and the Acquiring Fund will not exceed 90 days.
 
As a matter of policy, under normal market conditions, the Trust will be fully
invested in, and the Acquiring Fund will invest at least 80% of its net 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.
 
   
INVESTMENT RESTRICTIONS.  The fundamental investment restrictions of the Trust
and the Acquiring Fund are substantially identical except for the following
differences:
    
 
(1) The Acquiring Fund may not purchase securities of any one issuer, other than
obligations issued or guaranteed by the U.S. Government or its agencies or
instrumentalities, if, immediately after such purchase, more than 5% of the
value of the Acquiring Fund's total assets would be invested in such issuer, or
the Acquiring Fund would hold more than 10% of the outstanding voting securities
of the issuer, except that up to 25% of the value of the Acquiring 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. The Trust may not purchase securities or make any investments
other than those described under "Investment Objective and Policies" in its
Prospectus, which is limited to securities issued or guaranteed by the U.S.
Government, its agencies or instrumentalities, repurchase agreements relating to
such securities and in certain securities of other investment companies.
 
                                        9
<PAGE>   103
   
 
(2) The Trust may not borrow money except from banks for temporary or emergency
non-investment purposes, such as to accommodate abnormally heavy redemption
requests, and then only in an amount not exceeding 10% of the value of the
Trust's total assets at the time of borrowing; provided that so long as any
borrowings exceed 5% of the value of the Trust's total assets, the Trust will
not purchase portfolio securities. The Acquiring Fund has a similar policy
except its policy provides that the Acquiring Fund may not borrow money or issue
senior securities, except that the Acquiring 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 the Acquiring Fund's total assets
at the time of such borrowing and except as permitted pursuant to an exemption
from the 1940 Act. The Acquiring Fund will not purchase securities while its
borrowings (including reverse repurchase agreements and dollar roll agreements)
exceed 5% of its total assets.
 
(3) The Trust may not underwrite any securities issued by others. The Acquiring
Fund has a similar policy except that the Acquiring Fund may underwrite the
securities of others to the extent it may be deemed to be an underwriter under
certain securities laws in the disposition of "restricted securities."
 
(4) The Acquiring Fund may not purchase any securities on margin, except for
such short term credits as are necessary for the clearance of purchases of
portfolio transactions. The Trust has no such policy.
 
(5) The Trust may not purchase or sell oil and gas interests. The Acquiring Fund
has a similar policy except that such policy also excludes purchases of
participations or other direct interests in other mineral exploration or
development programs.
    
 
In addition, the Acquiring Fund has the following non-fundamental investment
restrictions. Except as noted below, these non-fundamental investment
restrictions are substantially similar to fundamental investment restrictions of
the Trust. As discussed above, however, fundamental restrictions of a fund may
not be changed without a vote of a majority of the outstanding voting securities
of the fund; non-fundamental policies may be changed without a shareholder vote.
As a consequence, the following policies could be modified, or eliminated, by
the Group with respect to the Acquiring Fund without shareholder approval.
 
(1) The Acquiring Fund may not engage in any short sales.
 
(2) The Acquiring Fund may not (a) purchase or otherwise acquire any securities
if as a result, more than 10% of the Acquiring Fund's net assets would be
invested in securities that are illiquid or (b) invest more than 15% of the
Acquiring Fund's total assets in securities which are restricted as to
disposition. The Trust has a fundamental policy that provides that it may not
enter into a repurchase agreement maturing in more than seven days or knowingly
purchase securities which are subject to restrictions on resale or for which
there is no readily available market if, as a result, more than 10% of the value
of the Trust's total assets at the time would be invested in such securities.
   
 
PORTFOLIO MANAGERS.  Since CMC serves as the investment adviser to both the
Trust and the Acquiring Fund, the person currently serving as portfolio manager
for the Trust intends to serve after the Reorganization as portfolio manager for
the Acquiring Fund.
    
 
It is not anticipated that the above-mentioned differences in investment
policies and restrictions will, individually or in the aggregate, result in an
appreciable variation between the level of investment risks associated with an
investment in the Trust. For a more complete description of the Acquiring Fund's
investment policies and restrictions, including relevant risk factors, see "WHAT
ARE THE INVESTMENT OBJECTIVES AND POLICIES OF THE FUND?" in the Acquiring Fund's
Prospectus and "INVESTMENT OBJECTIVES AND POLICIES" in the Acquiring Fund's
Statement of Additional Information. For a more complete description of the
Trust's investment policies and restrictions, including relevant risk factors,
see "WHAT ARE THE INVESTMENT OBJECTIVES AND POLICIES OF THE TRUST?" in the
Trust's Prospectus and "INVESTMENT OBJECTIVES AND POLICIES" in the Trust's
Statement of Additional Information.

Pursuant to the laws of the Commonwealth of Pennsylvania and the Trust's Amended
Declaration of Trust, the responsibility for the management of the Trust is
vested in its Board of Trustees which, among other things, is empowered by the
Trust's Amended Declaration of Trust to elect officers of the Trust and contract
with and provide for the compensation of agents, consultants, and other
professionals to assist and advise in such management.
    
 
   
INVESTMENT ADVISER.  The Trust is advised by Cardinal Management Corp. ("CMC"),
155 East Broad Street, Columbus, Ohio 43215, a wholly owned subsidiary of The
Ohio Company. CMC is also the investment adviser and manager of each of the
other Cardinal Funds except The Cardinal Fund Inc., which is advised by The Ohio
Company. CMC was established as an Ohio corporation on March 21, 1980, and has
been providing investment advisory services to open-end management investment
companies like the Trust since 1980.
    
 
   
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.
    
 
In its capacity as investment adviser, and subject to the ultimate authority of
the Trust's Board of Trustees, CMC, in accordance with the Trust's investment
objectives and policies, manages the Trust, and makes decisions with respect to
and places orders for all purchases and sales of its portfolio securities. In
addition, pursuant to the Investment Advisory Agreement, the Adviser generally
assists in all aspects of the Trust's administration and operation. Since
December 22, 1995, John R. Carle has been primarily responsible for the
day-to-day management of the Trust's portfolio. Mr. Carle has been a portfolio

Except where shareholder action is required by law, all of the authority of the

CERTAIN FINANCIAL INFORMATION.  The Prospectus for the Trust contains
information on per share income, capital changes and performance calculations
under the caption "FINANCIAL HIGHLIGHTS."
 
The Acquiring Fund has not yet commenced operations and has no and will have no
assets or liabilities prior to the consummation of the Reorganization.
Therefore, no information regarding per share income and capital changes is
available. For information regarding performance calculations and comparisons,
see the information under the caption "PERFORMANCE INFORMATION" in the Acquiring
Fund's Prospectus.
 
COMPARISON OF RIGHTS OF SECURITY HOLDERS.  The Trust is a Pennsylvania business
trust, registered under the 1940 Act as an open-end investment company of the
management type. The Trust was established under an Amended Declaration of Trust
dated April 24, 1980. The Group is an Ohio business trust, registered under the
1940 Act as an open-end investment company of the management type. The Group was
established under a Declaration of Trust dated as of March 23, 1993. Both the
Trust and the Group are authorized to issue an unlimited number of shares of
beneficial interest, and such shares may be divided into one or more series and
for the Group, separate classes of shares. The Acquiring Fund is one of six
series of the Group. The other five series of the Group are The Cardinal Fund,
Cardinal Government Obligations Fund, Cardinal Tax Exempt Money Market Fund,
Cardinal Balanced Fund and Cardinal Aggressive Growth Fund.
 
Each share of the Trust is of equal rank, constitutes a single class of shares
in the Trust and is identical in all respect except as may be fixed by the
Trustees pursuant to the Amended Declaration of Trust. Shares of the Trust
issued pursuant to the Trust's Amended Declaration of Trust are fully paid and
nonassessable and have no preemptive rights or other preferences or conversion
rights except to the extent set by the Trustees. Shareholders of the Trust have
no appraisal or dissenters' rights.
 
Shares of the Acquiring Fund, once properly issued and outstanding, are fully
paid and nonassessable and have no preference as to conversion, exchange,
dividends, retirement or other features, and have no preemptive or appraisal
rights.
 
Shareholders of the Trust are entitled to one vote for each full Share held and
a proportionate fractional vote for each fractional Share held. Shareholders of
the Acquiring Fund are entitled to one vote for each dollar of value invested
and a proportionate fractional vote for any fraction of a dollar invested.
 
Voting rights of the Trust's Shareholders are not cumulative, so that the
holders of more than 50% of the Trust voting in the election of its Trustees
have the power to elect all of the Trustees of the Trust. The Trust currently
holds an annual meeting of shareholders.
 
Shareholders of the Group have no cumulative voting rights, which means that the
holders of a plurality of the shares voting for the election of the Group's
Board of Trustees can elect all of the Group's Board of Trustees if they choose
to do so. The Group does not intend to hold annual meetings of shareholders,
except as required under its Declaration of Trust or the 1940 Act. Shareholders
of the Acquiring Fund will vote in the aggregate with other shareholders of the
Group and not by series or portfolio except as otherwise expressly required by
law. For example, shareholders of the Acquiring 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 Acquiring Fund will vote as a Fund, and not in the aggregate
with other
 
                                       13
<PAGE>   107
 
shareholders of the Group, for purposes of approval of amendments to the
Acquiring Fund's investment advisory agreement or any of the Acquiring Fund's
fundamental policies.
 
Therefore, after the Reorganization, shareholders of the Acquiring Fund alone
may not be able to elect the Trustees of the Group or ratify the selection of
independent accountants but will vote with all the other shareholders of the
Group on such issues if and when presented to shareholders. In addition,
shareholders of the Group receive one vote for each dollar of value invested;
therefore, a shareholder of one share of the Acquiring Fund will receive one
vote for such share while a holder of one share of another non-money market fund
of the Group will receive more than one vote for such share, e.g., a share of
Cardinal Balanced Fund with a net asset value of $9.50 will be entitled to 9.5
votes. In addition, since the Group currently does not intend to hold annual
meetings unless otherwise required to do so, it can not be determined when
shareholders of the Acquiring Fund will next be entitled to vote for the
election of Trustees or the ratification of the selection of independent public
accountants.

THE TRUST'S BOARD OF TRUSTEES AND MANAGEMENT RECOMMEND APPROVAL OF THE PLAN.
 
   
                        ELECTION OF TRUSTEES -- ISSUE 2
    
 
   
It is the present intention that the enclosed proxy will be used for the
purposes of voting in favor of the election of each of the following ten
nominees as a trustee to hold office until the next annual meeting and until his
successor is elected and qualified. Each of the nominees is a member of the
present Board of Trustees of the Trust and, except for Mr. Allen, each has been
elected by shareholder vote. Pursuant to Rule 14a-4(d) under the Securities
Exchange Act of 1934, each nominee has consented to be named in this Combined
Prospectus/Proxy Statement and to serve if elected. It is not expected that any
of the nominees will decline or become unavailable for election, but in case
this should happen, the discretionary power given in the proxy may be used to
vote for a substitute nominee or nominees.

WHEREAS, TCG is registered under the Investment Company Act of 1940, as amended
("1940 Act"), as an open-end investment company of the management type and has,
or before the Exchange Date (as defined below) is expected to have, issued and
outstanding one class of shares of beneficial interest, without par value
("Shares"), for each of six series, one such series being Cardinal Government
Securities Money Market Fund (hereinafter sometimes referred to as the "Cardinal
Government Securities Money Market Fund" or the "Acquiring Series"); and
 
WHEREAS, CGST is registered under the 1940 Act as an open-end investment company
of the management type and currently has issued and outstanding one class of
shares of beneficial interest, par value $.01 per share; and
 
WHEREAS, CGST plans to transfer all of its assets, and to assign all of its
liabilities, to the Acquiring Series, in exchange for Shares of the Acquiring
Series (the "Acquiring Series Shares"), followed by the distribution of the
Acquiring Series Shares by CGST to its shareholders, and followed by the
dissolution of CGST, all upon the terms and provisions of this Agreement (the
"Reorganization"); and
 
WHEREAS, this Agreement is intended to be and is adopted as a plan of
reorganization and liquidation within the meaning of Section 368(a) of the
United States Internal Revenue Code of 1986, as amended (the "Code"); and
 
WHEREAS, the trustees of TCG have determined that the Reorganization is in the
best interests of TCG, and that the interests of its shareholders will not be
diluted as a result thereof; and
 
WHEREAS, the trustees of CGST have determined that the Reorganization is in the
best interests of CGST and that the interests of its shareholders will not be
diluted as a result thereof;
 
NOW, THEREFORE, in consideration of the mutual promises herein contained, the
parties hereto covenant and agree as follows:
 
1.  PLAN OF REORGANIZATION AND LIQUIDATION.
 
(a) Sale of Assets, Assumption of Liabilities.  Subject to the prior approval of
shareholders of CGST and to the other terms and conditions contained herein
(including the obligation of CGST to distribute to its shareholders all of its
investment company taxable income and net capital gain as described in Section
8(i) herein), CGST agrees to sell, assign, convey, transfer and deliver to the
Acquiring Series, and the Acquiring Series agrees to acquire from CGST on the
Exchange Date (as defined below), all of the Investments (as defined below),
cash and other assets of CGST in exchange for that number of full and fractional
Acquiring Series Shares of the Acquiring Series having an aggregate net asset
value equal to the value of all assets of CGST transferred to the Acquiring
Series, as provided in Section 4, less the liabilities of CGST assumed by the
Acquiring Series.
 
(b) Assets Acquired.  The assets to be acquired by the Acquiring Series from
CGST shall consist of all of CGST's property, including, without limitation, all
Investments, cash and dividends or interest receivables which are owned by CGST
and any deferred or prepaid expenses shown as an asset on the books of CGST as
of the Valuation Time described in Section 4.
 
(c) Liabilities Assumed.  Prior to the Exchange Date CGST will endeavor to
discharge or cause to be discharged, or make provision for the payment of, all
of its known liabilities and obligations. The Acquiring Series shall assume all
liabilities, expenses, costs, charges and reserves of CGST, contingent or
otherwise, including liabilities reflected in the unaudited statement of assets
and liabilities of CGST
 
                                       A-1
<PAGE>   115
 
as of the Valuation Time, prepared by or on behalf of CGST in accordance with
generally accepted accounting principles consistently applied from and after
September 30, 1995.
 
(d) Liquidation and Dissolution.  Upon consummation of the transactions
described in Section 1(a), 1(b) and 1(c) above, CGST shall distribute in
complete liquidation to its shareholders of record as of the Exchange Date the
Acquiring Series Shares received by it, each CGST shareholder of record being
entitled to receive that number of Acquiring Series Shares equal to the
proportion which the number of shares of beneficial interest, par value $.01 per
share, of CGST held by such shareholder bears to the total number of such shares
of CGST outstanding on such date, and shall take such further action as may be
required, necessary or appropriate under CGST's Amended Declaration of Trust,
Pennsylvania law and the Code to effect the complete liquidation and dissolution
of CGST. CGST will fulfill all reporting requirements under the 1940 Act, both
before and after the Reorganization.

warrants to and agrees with TCG and the Acquiring Series that:

(b) CGST is registered under the 1940 Act as an open-end investment company of

investments shown on the statement of assets and liabilities as of September 30,
1995 referred to in Section 2(c) hereof, as supplemented with such changes as

Agreement, which changes have been disclosed to TCG, and changes made on and
after the date of this Agreement after advising CGST of such changes, and
changes resulting from stock dividends stock split-ups, mergers and similar
corporate actions.
 
(i) CGST has filed or will file all federal and state tax returns which, to the
knowledge of CGST's officers, are required to be filed by CGST and has paid or

assessments received by CGST. All tax liabilities of CGST have been adequately

Revenue Service or by any state or local tax authority for taxes in excess of
those already paid.

and the Acquiring Series pursuant to this Agreement. At the Exchange Date,
subject only to the delivery of the Investments and any such other assets and
liabilities as contemplated by this Agreement, TCG and the Acquiring Series will
acquire the Investments and any such other assets subject to no encumbrances,
liens or security interests in favor of any third party creditor of CGST and,
except as described in Section 2(k), without any restrictions upon the transfer
thereof.
 
(k) No registration under the Securities Act of 1933, as amended (the "1933

                                CARDINAL FUNDS

                                                                January 26, 1996
    
 
Dear Cardinal Tax Exempt Money Trust Shareholder:
 
   
The Board of Trustees of Cardinal Tax Exempt Money Trust (the "Trust") recently
reviewed and unanimously approved a proposal to reorganize the Trust with and
into a newly created series of The Cardinal Group (the "Group"). This Agreement
and Plan of Reorganization and Liquidation is described in the accompanying
Combined Prospectus/Proxy Statement and will be addressed at the Annual Meeting
of Shareholders on March 15, 1996.
    
 
The primary purpose of the proposed reorganization is to achieve certain
economies of scale by having the Trust become an additional series of the Group
rather than operate as a separate stand-alone investment company. By operating
more efficiently, we expect to realize cost savings through the elimination of
certain Annual Meeting expenses, a reduction of printing and mailing
expenditures, the lowering of regulatory filing expenses and the reduction of
professional fees. The Board determined that such a reorganization is in the
best interest of the Trust.
 
   
If the proposed reorganization is approved, you will receive shares of the newly
created series of the Group, known as Cardinal Tax Exempt Money Market Fund, in
exchange for your shares of the Trust. Shares received in this distribution will
be equal in value at the time of reorganization to your shares in the Trust.
There will be no adverse federal income tax consequences associated with this
distribution.
    
 
As a result of the reorganization, many features of the new series will be the
same as those of the Trust. For instance, the securities in the underlying
portfolio will remain the same. Purchase and redemption procedures will not
change. Slight differences in investment policies and restrictions are proposed
but are not expected to increase the level of risk associated with your
investment.
 
   
Please read the accompanying materials carefully. For more details regarding the
proposed reorganization, direct any questions you may have to the Treasurer of
the Trust, Mr. James Schrack, at (800) 282-9446. IT IS VERY IMPORTANT THAT YOU
COMPLETE AND RETURN THE PROXY CARD AS SOON AS POSSIBLE.
    
 
Thank you for your support and investment in Cardinal Tax Exempt Money Trust.
 
                                          Sincerely,
 
                                          FRANK W. SIEGEL, CFA
                                          President
                                          Cardinal Tax Exempt Money Trust

Cardinal Tax Exempt Money Trust, an Ohio business trust (the "Trust"), in
connection with the solicitation of proxies by the Board of Trustees of the
Trust to be used at the Annual Meeting of Shareholders of the Trust (the
"Meeting"), to be held at The Athletic Club of Columbus, 136 East Broad Street,
Columbus, Ohio 43215 on Friday, March 15, 1996, beginning at 9:30 A.M. (Eastern
Time).
    
 
In addition to the customary annual election of Trustees and ratification of the
selection of independent accountants, the Trustees of the Trust are seeking your
approval of an Agreement and Plan of Reorganization and Liquidation (the
"Plan"), which contemplates that Cardinal Tax Exempt Money Market Fund (the
"Acquiring Fund"), a series or portfolio of The Cardinal Group (the "Group"),
will acquire all of the assets of and will assume all of the liabilities of the
Trust in exchange for shares of the Acquiring Fund.
 
Following such exchange, the shares of the Acquiring Fund received by the Trust
will be distributed to the Trust's shareholders and the Trust will be liquidated
and dissolved. This exchange and distribution transaction is sometimes referred
to herein as the "Reorganization."
 
This Combined Prospectus/Proxy Statement, which should be retained for future
reference, sets forth concisely the information about the Acquiring Fund that a
prospective investor, including shareholders of the Trust, should know before
investing. Additional information about the Reorganization and the Acquiring
Fund is contained in a separate Statement of Additional Information which has
been filed with the Securities and Exchange Commission (the "Commission") and is
available upon request without charge by calling the Group at (800) 282-9446 or
writing to the Group at the address set forth above. The Statement of Additional
Information bears the same date as this Combined Prospectus/Proxy Statement and
is incorporated by reference herein.
 
THE SHARES OF THE ACQUIRING 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 ACQUIRING FUND
INVOLVES CERTAIN INVESTMENT RISKS, INCLUDING THE POSSIBLE LOSS OF PRINCIPAL. THE
ACQUIRING 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.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
   EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
     SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
        PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY
          REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
<PAGE>   128
 
Upon completion of the Reorganization, you will receive full and fractional
shares of the Acquiring Fund equal in value when issued to the shares of the
Trust owned by you immediately prior to the Reorganization. No commissions or
sales loads will be charged in connection with the Reorganization and there will
be no adverse federal income tax consequences. You should separately consider
any other tax consequences in consultation with your tax advisers.
 
   
As discussed in detail herein, the investment objectives and strategy of the
Acquiring Fund are substantially similar to those of the Trust. There are some
differences between investment policies and restrictions, as well as differences
in fees and in voting rights, which are described in detail below. The
Prospectus of the Acquiring Fund relating to its shares, dated January 10, 1996,
is incorporated by reference in this Combined Prospectus/Proxy Statement and
accompanies this Combined Prospectus/Proxy Statement.
    
 
   
The Trust's Prospectus dated January 19, 1996, contains additional information
about the Trust, has been filed with the Commission, is incorporated by
reference herein and is available without charge by writing the Trust at 155
East Broad Street, Columbus, Ohio 43215, or by calling the Trust at (800)
282-9446. Copies of documents requested will be sent by first-class mail to the
requesting shareholder within one business day of the request.

                                    GENERAL
 
   
This Combined Prospectus/Proxy Statement is furnished in connection with the
solicitation of proxies by the Board of Trustees of the Trust to be used in
connection with the Meeting to be held on Friday, March 15, 1996.
    
 
The management knows of no business which will be presented for consideration
other than that mentioned in Issues 1, 2, 3 and 4 of the Notice of Annual
Meeting of Shareholders. If any other matters are properly presented at the
Meeting or any adjournment(s) thereof, it is the intention of the persons named
therein to vote the proxies in accordance with their judgment on such matters.
 
   
The Board of Trustees has fixed the close of business on January 22, 1996, as
the record date for the determination of shareholders entitled to notice of and
to vote at the Meeting (the "Record Date"). On the Record Date there were
75,444,612 shares of beneficial interest, $0.10 par value per share ("Shares"),
of the Trust outstanding and entitled to vote. Each of the Shares is entitled to
one vote. Shareholders of fractional Shares will be entitled to a vote of such
fraction. Shareholders holding one third of the outstanding Shares of the Trust
will be deemed to constitute a quorum for the transaction of business at the
Meeting.
    
 
The expenses for preparation, printing and mailing of the enclosed proxy,
accompanying notice and Combined Prospectus/Proxy Statement, or any
re-solicitation of the foregoing, will be paid in part by the Trust and in part
by The Ohio Company.
 
Only shareholders of record at the close of business on the Record Date will be
entitled to notice of and to vote at the Meeting. Shares represented by
management proxies, unless previously revoked, will be voted at the Meeting in
accordance with the instructions of the shareholders. If no instructions are
given, the proxies will be voted in favor of the proposals. To revoke a
management proxy, the shareholder giving such proxy must either submit to the
Trust a subsequently dated proxy, deliver to the Trust a written notice of
revocation or otherwise give notice of revocation in open meeting, in all cases
prior to the exercise of the authority granted in the management proxy.
 
In the event that sufficient votes are not received by the Meeting date, a
person named as proxy may propose one or more adjournments of the Meeting for a
period or periods of not more than 45 days in the aggregate to permit further
solicitation of proxies. Any such adjournment will require the affirmative vote
of the holders of a majority of the Trust's Shares present at the Meeting in
person or by proxy. The persons named as proxies will vote in favor of such
adjournment those proxies which they are entitled to vote in favor of the
proposals and will vote against any such adjournment those proxies required to
be voted against the proposals.
 
   
The mailing address of the principal executive offices of the Trust is 155 East
Broad Street, Columbus, Ohio 43215. The approximate date on which this Combined
Prospectus/Proxy Statement and form of proxy are first sent to shareholders is
on or about January 31, 1996.
    
 
   
As of the Record Date, the Acquiring Fund had no shares outstanding. The
Acquiring Fund does not have, and will not have immediately prior to the
effective date of the Reorganization, any assets or liabilities nor will it have
commenced operations.
    
 
Any proxy which is properly executed and received in time to be voted at the
Meeting will be counted in determining whether a quorum is present and will be
voted in accordance with the instructions marked thereon. Abstentions and
"broker non-votes" (i.e., proxies from brokers or nominees indicating that such
persons have not received instructions from the beneficial owners or other
persons entitled to vote shares as to a particular matter with respect to which
the brokers or nominees do not have discretionary power to vote) will be counted
for purposes of determining whether a quorum is present. For purposes of
determining whether a proposal has been approved, abstentions and broker
non-votes will have the effect of a vote against the proposal in those instances
where approval of an issue requires a certain percentage of all votes
outstanding or of the votes constituting the quorum.

                        APPROVAL OF THE PLAN -- ISSUE 1
    
 
SUMMARY
 
   
This Summary is qualified in its entirety by reference to the additional
information contained elsewhere in this Prospectus/Proxy Statement, the Plan, a
copy of which is attached to this Prospectus/Proxy Statement as Exhibit A, the
accompanying Prospectus of the Acquiring Fund dated January 10, 1996, and the
Prospectus of the Trust dated January 19, 1996.
    
 
   
PROPOSED REORGANIZATION. The Plan provides for the transfer of all of the assets
of the Trust to the Acquiring Fund in exchange for shares of the Acquiring Fund
and the assumption by the Group on behalf of the Acquiring Fund of all of the
liabilities of the Trust. The Plan also calls for the distribution of shares of
the Acquiring Fund to the Trust's shareholders in complete liquidation of the
Trust. (The foregoing proposed transactions are referred to in this
Prospectus/Proxy Statement as the "Reorganization.") As a result of the
Reorganization, each shareholder of the Trust will become the owner of that
number of full and fractional shares of the Acquiring Fund having an aggregate
value equal to the aggregate value of the shareholder's Shares of the Trust as
of the close of business on the day preceding the date that the Trust's assets
are exchanged for shares of the Acquiring Fund. Proposals for similar
reorganizations with and into other series of the Group are simultaneously being
made to shareholders of The Cardinal Fund Inc., Cardinal Government Obligations
Fund and Cardinal Government Securities Trust, the other series of the Cardinal
family of funds.
    
 
   
For the reasons set forth below under "THE PROPOSED TRANSACTION -- REASONS FOR
THE REORGANIZATION," the Board of Trustees of the Trust, including the Trustees
of the Trust (the "Independent Trustees") who are not "interested persons" as
that term is defined in the Investment Company Act of 1940, as amended (the
"1940 Act"), at a special meeting held on November 13, 1995, unanimously
concluded that the Reorganization will be in the best interests of the Trust and
its shareholders and that the interests of the Trust's existing shareholders
will not be diluted as a result of the transaction contemplated by the
Reorganization and therefore has submitted the Plan for approval by the Trust's
shareholders. The Board of Trustees of the Group has reached similar conclusions
with respect to the Acquiring Fund and has also approved the Reorganization in
respect of the Acquiring Fund.
    
 
Approval of the Reorganization will require the affirmative vote of at least
two-thirds of the Shares of the Trust outstanding and entitled voted on the
matter. See "APPROVAL AND CONSUMMATION OF THE PROPOSED TRANSACTION" below.
 
COMPARATIVE EXPENSE INFORMATION. The purpose of the following tables is to
assist shareholders of the Trust in understanding the costs and expenses that a
shareholder in the Acquiring Fund would bear directly or indirectly. The
shareholder transaction expenses for the Acquiring Fund are estimated for the
fiscal period following the Reorganization and ending September 30, 1996. The
expenses of the Trust are based upon the fiscal year ended September 30, 1995.

FEDERAL INCOME TAX CONSEQUENCES. Prior to completion of the Reorganization, the
Trust will have received an opinion of counsel that, upon the consummation of
the Reorganization, no gain or loss will be recognized by the Trust or its
shareholders for federal income tax purposes. The holding period and aggregate
tax basis for the Acquiring Fund shares that are received by a Trust shareholder
will be the same as the holding period and aggregate tax basis of the Shares of
the Trust previously held by such shareholder. In addition, the holding period
and tax basis of the assets of the Trust in the hands of the Acquiring Fund as a
result of the Reorganization will be the same as the holding period and tax
basis of the assets in the hands of the Trust immediately prior to the
Reorganization.
    
 
   
APPROVAL AND CONSUMMATION OF THE PROPOSED TRANSACTION. The Board of Trustees of
the Trust, at a special meeting held on November 13, 1995, determined
unanimously that the Reorganization is in the best interests of the Trust and
that the interests of the existing shareholders of the Trust will not be diluted
as a result of the Reorganization. Similarly, the Board of Trustees of the Group
unanimously determined that the Reorganization is in the best interests of the
Group and the Acquiring Fund. The proposed Reorganization of the Trust with and
into the Acquiring Fund is part of a larger plan to reorganize each of the
Trust, Cardinal Government Obligations Fund, Cardinal Government Securities
Trust and The Cardinal Fund Inc., each a separate stand-alone investment
company, with and into a separate portfolio of the Group, and will allow the
shareholders of the Trust to realize certain economies of scale as a result of
becoming shareholders of a series investment company and thus having certain
fixed fees spread over a larger pool of assets. In addition, the corporate
structure of and the more uniform investment policies and restrictions of the
Acquiring Fund will improve oversight of compliance obligations and overall
management of the shareholders' investment since many of such policies and
restrictions will be the same for all of the series or portfolios of the Group.
See "THE PROPOSED TRANSACTION -- REASONS FOR THE PROPOSED TRANSACTION" below.
    
 
To be approved, the Plan will require the affirmative vote of the holders of at
least two-thirds of the Shares of the Trust entitled to vote on the matter. The
Reorganization with respect to the Trust is not contingent on the approval of
the Reorganization with respect to any of the other Cardinal funds. If the
Trust's shareholders do not approve the proposed Reorganization, the Trust's
Board of Trustees will consider what other alternatives would be in the
shareholders' best interests. If the Plan is approved at the Meeting, the
effective date of the Reorganization (the "Closing Date") is expected to be on
or about March 31, 1996, subject, however, to the receipt by the Trust and the
Group, if necessary, of an order of exemption from the Commission with respect
to the Reorganization.
 
INVESTMENT OBJECTIVES AND POLICIES. The Trust and the Acquiring Fund have the
same investment objectives, and generally have the same investment policies and
restrictions. Each of the Trust and the Acquiring Fund seek to maximize current
income exempt from federal income tax while preserving capital and maintaining
liquidity. In order to achieve these objectives each has a policy of investing
at least 80% of its net assets in a diversified portfolio of Municipal
Securities (as defined below under "Comparison of Investment Objectives,
Policies and Restrictions -- Investment Objectives and
 
                                        3
<PAGE>   133
 
Policies"), 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. For a discussion of the differences between the investment restrictions of
the Acquiring Fund and the Trust, see "COMPARISON OF INVESTMENT OBJECTIVES,
POLICIES AND RESTRICTIONS -- INVESTMENT RESTRICTIONS."
 
   
FEES AND EXPENSES. Each of the Trust and the Acquiring Fund pay the following
fees: to Cardinal Management Corp. ("CMC") an investment advisory and management
fee computed daily and payable monthly at the annual rate of 0.50% of the value
of its average daily net assets; and to CMC for transfer agency services an
annual fee, paid monthly, at an annual rate of $21 per shareholder account plus
out-of-pocket expenses.
    
 
   
The Trust pays to CMC for fund accounting services a fee equal to $9,000 for the
first $25 million of assets, $6,000 for the next $25 million of assets, $3,000
for each additional $25 million to $350 million of assets, and $3,000 for each
additional $100 million of assets thereafter. The Acquiring Fund also pays to
CMC for fund accounting services a fee computed daily and paid periodically at
an annual rate of .03% of its average daily net assets of $100 million or less
and .01% of its average daily net assets in excess of $100 million.
    
 
Shares of each of the Trust and the Acquiring Fund are distributed by The Ohio
Company, a registered broker-dealer and the sole shareholder of CMC. Neither the
Trust nor the Acquiring Fund pays any distribution fees or expenses nor is any
sales charge imposed upon the sale of its shares.
 
The expense ratio of the Acquiring Fund subsequent to the Reorganization is
expected to be slightly lower than that of the Trust. See "THE PROPOSED
TRANSACTION -- REASONS FOR THE PROPOSED TRANSACTION." The total annual operating
expenses of the Trust as of September 30, 1995, were 0.83% as a percentage of
average net assets. Assuming the same level of net assets for the Acquiring Fund
after the Reorganization, it is estimated that the total annual operating
expenses for the Acquiring Fund stated as a percentage of average net assets
would be 0.82%.
 
COMPARISON OF PURCHASE AND REDEMPTION PROCEDURES. Shares of the Trust and the
Acquiring Fund are offered at net asset value and may be purchased through The
Ohio Company on each day the New York Stock Exchange is open for business (a
"Business Day"). The minimum initial investment in both the Trust and the
Acquiring Fund is $1,000, the minimum subsequent investment is $100 and there is
no sales charge imposed upon the purchase of shares or upon the reinvestment of
dividends and distributions.
 
Redemption orders for shares of both the Trust and the Acquiring Fund must be
placed with CMC. Proceeds of redemption requests received by CMC 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.
 
COMPARISON OF EXCHANGE PRIVILEGES. Shares of the Trust and of the Acquiring Fund
may be exchanged for shares of any other fund advised by The Ohio Company or CMC
(a "Cardinal Fund") at respective net asset values, although a sales charge may
be applicable upon exchanges of shares for a Cardinal Fund sold with a sales
charge.
 
COMPARISON OF DIVIDEND POLICIES. Each of the Trust and the Acquiring Fund
declare dividends daily and pay dividends from net investment income monthly.
Each of the Trust and Acquiring Fund will distribute all of any capital gains at
least annually. In addition, shareholders of the Trust and the Acquiring Fund
receive dividends and distributions in the form of additional shares and not in
cash unless otherwise requested by the shareholder.
 
COMPARISON OF VOTING RIGHTS. Each shareholder of the Trust is entitled to one
vote for each full share held and a proportionate fractional vote for each
fractional share held on each matter submitted to the vote of the Trust's
shareholders, regardless of the net asset value of such share. Each shareholder
of
 
                                        4
<PAGE>   134
 
the Acquiring Fund, however, is entitled to one vote for each dollar of value
invested and a proportionate fractional vote for any fraction of a dollar
invested.
 
SPECIAL CONSIDERATIONS AND RISK FACTORS
 
Because the investment objectives, policies, strategies and restrictions of the
Trust and the Acquiring Fund are substantially similar, the overall level of
investment risk should not materially change as a result of the Reorganization.
There can be no assurance that either the Trust or the Acquiring Fund will
achieve its investment objectives or be able continuously to maintain a net
asset value per share of $1.00.
 
The following discussion is qualified in its entirety by the disclosure set
forth in the Acquiring Fund's Prospectus accompanying this Combined
Prospectus/Proxy Statement and the Trust's Prospectus. For additional
information, see "Comparison of Investment Objectives, Policies and
Restrictions" and "Additional Comparative Information," below.
 
VARIABLE RATE SECURITIES. The Trust and the Acquiring Fund invest or intend to
invest more than 25% of their 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 Trust or the Acquiring Fund (as the case may be) 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
Trust and the Acquiring 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 indices (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 Trust and
the Acquiring 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. To the extent the Trust's or the Acquiring
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
its 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, neither the Trust nor the Acquiring Fund has any limit as to the
percentage of its total assets that may be invested in such variable or floating
rate securities.
 
The characteristics of short-term Municipal Securities are such that the price
stability and liquidity of a fund which invests in such securities may not be
equal to that of a money market fund which exclusively invests in short-term
taxable money market securities. While CMC believes that the purchase of
variable rate demand Municipal Securities will facilitate maintaining a $1.00
per share net asset value, each of the Trust and the Acquiring Trust is still
expected to have a significantly longer average maturity than a general purpose
taxable money market fund with the result that the pricing of its portfolio will
tend to be more subject to short-term interest rate fluctuations.
 
CONCENTRATION.  Variable rate demand Municipal Securities in which the Trust and
the Acquiring Fund invest may be supported by bank letters of credit or
comparable guarantees of financial institutions. To the extent that 25% or more
of the Trust's or the Acquiring Fund's assets are invested in variable rate

Acquiring Fund, as the case may be, may be deemed to be concentrated in the
banking industry. 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.
 
WHEN-ISSUED AND DELAYED-DELIVERY TRANSACTIONS.  Each of the Trust and the
Acquiring Fund may also purchase securities on a when-issued or delayed-delivery
basis. The Trust and the Acquiring 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. Such securities are not paid for or do not
start earning interest until they are received although the payment obligation
and the coupon rate have been established before the time the mutual fund enters
into the commitment. When the Trust or the Acquiring 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 mutual fund relies on the seller to
complete the transaction; the seller's failure to do so may cause such fund to
miss a price or yield considered to be advantageous.
 
Neither the Trust's nor the Acquiring Fund's commitments to purchase when-issued
securities will 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 CMC to manage it might be adversely affected.
 
TAXABLE MONEY MARKET SECURITIES.  Under normal operating circumstances, the
Trust's and the Acquiring Fund's assets will be managed with a view towards
producing only income that is exempt from federal income taxation. However, the
Trust and the Acquiring Fund may each invest up to 20% of its respective 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 ("FDIC"), bankers'
acceptances, high-grade commercial paper guaranteed or issued by domestic
corporations and repurchase agreements secured by such obligations.
 
REPURCHASE AGREEMENTS.  Securities held by each of the Trust and the Acquiring
Fund may be subject to repurchase agreements. Under the terms of a repurchase
agreement, the Trust or the Acquiring Fund acquires 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 CMC deems creditworthy under
guidelines approved by the respective Boards of Trustees. At the time of
purchase, the bank or securities dealer agrees to repurchase the underlying
securities 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. Under the 1940 Act,
repurchase agreements are considered to be loans by the Trust and the Acquiring
Fund. The Trust and the Acquiring 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 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. CMC will be responsible for continuously monitoring such requirements. In
the event of a bankruptcy or other default of a seller of a repurchase
agreement, the Trust or the Acquiring Fund, as the case may be, could experience
both delays in liquidating the underlying securities and losses, including:
 
                                        6
<PAGE>   136
 
(a) possible decline in the value of the underlying securities during the period
while seeking 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.
 
LOAN PARTICIPATIONS.  The Trust and the Acquiring Fund may each acquire
participations in privately negotiated loans to municipal borrowers, provided
that the interest received thereon is exempt, in the opinion of bond counsel to
the municipal borrower, from federal income tax. Loan participations are loans
subject to the Trust's and the Acquiring Fund's respective investment
restrictions applicable to these activities. See "Comparison of Investment
Objectives, Policies and Restrictions" below.
 
INVESTMENT COMPANY SECURITIES.  Each of the Trust and the Acquiring 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.
Such funds intend to invest in the securities of other money market mutual funds
for purposes of short-term cash management. Their investment in such other
investment companies may result in the duplication of fees and expenses,
particularly investment advisory fees.
 
THE PROPOSED TRANSACTION
 
AGREEMENT AND PLAN OF REORGANIZATION AND LIQUIDATION.  The Plan provides that
all of the assets of the Trust as of the Exchange Date (as defined in the Plan)
will be transferred to the Acquiring Fund in exchange for shares of the
Acquiring Fund and the assumption by the Acquiring Fund of all of the
liabilities of the Trust. The Closing Date is expected to be on or about March
31, 1996, subject, however, to the receipt by the Trust and the Group of any
necessary order of exemption from the Commission with respect to the
Reorganization. A copy of the Plan is attached as Exhibit A to this Combined
Prospectus/Proxy Statement. Although portions of the Plan are summarized below,
this summary is qualified in its entirety by reference to the Plan.
 
Promptly after the Exchange Date, the Trust will distribute the shares of the
Acquiring Fund to the Trust's shareholders of record as of the close of business
on the Exchange Date. The shares of the Acquiring Fund which will be issued for
distribution to the Trust's shareholders will be equal in aggregate value to the
Shares of the Trust held as of the Valuation Time (as defined in the Plan). All
issued and outstanding Shares of the Trust will be cancelled on the Trust's
books. Shares of the Acquiring Fund will be represented only by book entries; no
share certificates will be issued.
 
The consummation of the Reorganization is subject to the satisfaction of a
number of conditions set forth in the Plan, including approval by shareholders
of the Trust. The Plan also may be terminated and the Reorganization abandoned
by the Trust and the Acquiring Fund by mutual consent of their respective
trustees. If the consummation of the Reorganization is so abandoned, no party
shall be liable to the other party for any damages resulting therefrom. If the
Reorganization is otherwise not consummated by reason of either party's being
unwilling or unable to go forward (other than by reason of the non-fulfillment
or failure of certain conditions to such party's obligations), such party will
pay directly all reasonable fees and expenses incurred by the other party in
connection with the Reorganization.
 
The Reorganization also is subject to the condition of obtaining an opinion of
counsel to the effect that the Reorganization constitutes a tax-free
reorganization for federal income tax purposes and any necessary written order
of exemption from the Commission exempting the Reorganization from the
provisions of Section 17(a) of the 1940 Act.
 
Except as otherwise provided below, all fees and expenses incurred by a party in
connection with the Plan will be paid by the party directly incurring such costs
except where a party is unwilling or unable to go forward (other than for lack
of requisite shareholder approval or breach by the other party in its covenants)
in which case such party will pay all reasonable fees and expenses of the other
party. The Ohio Company will pay the costs associated with the Reorganization.
The Trust will pay those costs associated with that portion of the Meeting
relating to customary annual meeting matters (e.g., election of trustees), and
the Acquiring Fund will bear its organizational costs.
 
                                        7
<PAGE>   137
 
Shareholders of the Trust will have no dissenters' rights or appraisal rights.
If the Plan is duly approved by shareholders, all shareholders of the Trust as
of the Exchange Date, including those that voted against the approval of the
Plan, will receive shares of the Acquiring Fund. All shareholders of the Trust
have the right at any time up to the next business day preceding the Exchange
Date to redeem their Shares at net asset value according to the procedures set
forth in the Trust's Prospectus.
 
This summary does not purport to be a complete description of the Plan and is
subject to the terms and conditions of the Plan set forth in Exhibit A.
 
REASONS FOR THE PROPOSED TRANSACTION.  Currently, the Trust is a separate,
stand-alone investment company organized in 1983. The Group was organized as a
series investment company in 1993, and in October and November 1995, its Board
of Trustees created the Acquiring Fund with substantially identical investment
objectives, policies and restrictions to those of the Trust. Because of the
similarity between the Trust and the Acquiring Fund, the considerations and
risks involved with an investment in the Acquiring Fund are expected to be
comparable to those associated with an investment in the Trust. The Acquiring
Fund has been established for purposes of effecting the Reorganization and will
not commence operations prior to the Exchange Date.
 
The transactions contemplated by the Plan were presented to the Board of
Trustees of the Trust for their consideration at meetings held on October 20,
1995, and November 13, 1995. The Board of Trustees of the Trust concluded
unanimously that the Reorganization is in the best interests of the Trust and
that the interests of the existing shareholders of the Trust will not be diluted
by the Reorganization.
 
The Board of Trustees of the Trust, in reaching this conclusion, considered the
costs resulting from the separate operation of the Trust and the proposed costs
of the Acquiring Fund as provided by The Ohio Company, in light of their
substantially similar investment objectives, policies, restrictions, Boards of
Trustees, officers and service providers. The Board also considered the
operating and compliance efficiencies that could result from moving the
operation of the Trust from a stand-alone investment company to a separate
portfolio of a series investment company. The investment policies and
restrictions of the Acquiring Fund which were approved by the Board of Trustees
of the Group vary somewhat from the policies of the Trust; however, such
differences reflect a more uniform and flexible set of investment restrictions
that are currently in place for each of the other series or portfolios of the
Group. Such restrictions were approved to help achieve greater compliance
efficiencies by having each series of the Group have the same or substantially
the same investment restrictions.
 
In addition, certain operating efficiencies are expected to be achieved since
under Ohio law and the Group's Declaration of Trust an annual meeting of
shareholders of the Acquiring Fund is not required. The Trust under its
Declaration of Trust is required to hold such a meeting. Also, certain fixed
costs associated with the operation of the Trust when incurred by the Acquiring
Fund as part of the Group would decrease on a per share basis since such costs
would be spread over a larger pool of assets, e.g., certain legal and printing
fees, while maintaining the same services by the same service providers.
 
In particular, the Board considered the anticipated expense ratios of the
Acquiring Fund, the structure of the Group, the experience of the service
providers of the Acquiring Fund and the level of service to be provided to the
shareholders of the Acquiring Fund, as represented by The Ohio Company.
 
The Board of Trustees of the Trust based its decision to approve the proposed
transaction upon its consideration of a number of factors, including, among
other things:
 
(1) the terms and conditions of the Reorganization and whether it would result
in a dilution of the existing shareholders' interests;
 
(2) the similarity of the Trust's investment objectives, strategies and policies
with those of the Acquiring Fund, as well as the views of CMC that any
differences between the investment policies and restrictions of the Trust and
the Acquiring Fund should not materially increase investment risks;
 
                                        8
<PAGE>   138
 
(3) the experience and resources of CMC with respect to providing investment
management services, and the experience of and quality of services to be
provided by the Acquiring Fund's other service providers;
 
(4) the projected expense ratios and information regarding fees and expenses of
the Trust, the Acquiring Fund and other similar funds and the services being
offered to shareholders;
 
(5) the conditioning of the Reorganization on the receipt of a legal opinion
confirming the absence of any adverse federal tax consequences to the Trust or
its shareholders resulting from the Reorganization; and
 
(6) other factors as it deemed relevant.
 
In particular, the Board considered the following per share operating expense
ratios (total annual operating expenses expressed as a percentage of average net
assets) for Shares of the Trust for the year ended September 30, 1995, and as
estimated for the shares of the Acquiring Fund for the period following the
effective date of the Reorganization and ending September 30, 1996, after giving
effect to the Reorganization:

DESCRIPTION OF THE SECURITIES TO BE ISSUED.  Ownership in the Acquiring Fund is
represented by units of beneficial interest, without par value, of The Cardinal
Group (the "Group"), which is an open-end investment company of the management
type, organized as an Ohio business trust on March 23, 1993. The Acquiring Fund
is currently one of six separate series of the Group. Like the Trust, the
Acquiring Fund is diversified, as that term is defined in the 1940 Act.
Currently there is only one class of shares for the Acquiring Fund. Shareholders
of the Acquiring Fund are entitled to one vote for each dollar of value invested
and a proportionate fractional vote for any fraction of a dollar invested. See
"ADDITIONAL COMPARATIVE INFORMATION."
 
FEDERAL INCOME TAX CONSEQUENCES.  As a condition to the closing of the
Reorganization, the Trust and the Group must receive a favorable opinion from
Baker & Hostetler, counsel to both the Trust and the Group, substantially to the
effect that, for federal income tax purposes: (a) the Reorganization will
constitute a "tax-free" reorganization within the meaning of Section 368(a) of
the Internal Revenue Code of 1986, as amended (the "Code"); (b) no gain or loss
will be recognized by the Acquiring Fund or the Trust as a result of the
Reorganization; (c) no gain or loss will be recognized by shareholders of the
Trust upon the exchange of their Shares of the Trust for shares of the Acquiring
Fund; (d) the tax basis of the Acquiring Fund shares received by shareholders of
the Trust pursuant to the Reorganization will be the same as the basis of the
Shares of the Trust held immediately prior to the Reorganization; (e) the
holding period of the Acquiring Fund shares so received will include the period
during which the Trust shareholder held Shares of the Trust, provided such
Shares were held as a capital asset; (f) the tax basis of the Trust's assets
acquired by the Acquiring Fund will be the same as the basis of such assets
immediately prior to the Reorganization; and (g) the holding period of such
assets will include the period during which those assets were held by the Trust.
The Group and the Trust do not intend to seek a private letter ruling with
respect to the tax effects of the Reorganization.
 
   
CAPITALIZATION.  The following table shows the capitalization of the Trust as of
September 30, 1995. The Acquiring Fund has no and will have no assets or
liabilities or commence operations immediately

COMPARISON OF INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS
 
INVESTMENT OBJECTIVES AND POLICIES.  The investment objectives and policies of
the Trust are substantially similar to those of the Acquiring Fund. The
investment objectives of the Trust and Acquiring Fund are "fundamental," which
means that they may not be changed without the consent of a majority of such
fund's outstanding shares, as defined in the 1940 Act.
 
The investment objectives of each of the Trust and the Acquiring Fund are to
maximize current income exempt from federal income tax while preserving capital
and maintaining liquidity.
 
As money market funds, each of the Trust and the Acquiring Fund invests
exclusively in United States dollar-denominated instruments which are determined
by CMC and the Trustees to 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. All
securities or instruments in which the Trust and the Acquiring Fund invest have,
or are deemed to have, remaining maturities of 397 calendar days (thirteen
months) or less. The dollar-weighted average maturity of the obligations in each
of the Trust and the Acquiring Fund will not exceed 90 days.
 
As a matter of policy, under normal market conditions, each of the Trust and the
Acquiring 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, each of the Trust
and the Acquiring Fund expects to invest in the following types of securities:
bond anticipation notes, construction loan notes, project notes, revenue
anticipation notes and tax anticipation notes, as well as municipal bonds and
participation interests therein, including industrial development revenue bonds
and pollution control revenue bonds (collectively, "Municipal Securities"). The
Trust, however, unlike the Acquiring Fund, may also acquire "stand-by
commitments" with respect to Municipal Securities held in its portfolio. Under a
"stand-by commitment" a dealer agrees to purchase, at the Trust's option,
specified Municipal Securities at a specified price which ordinarily is
substantially the same as the value of the underlying Municipal Security.
 
Specific types of Municipal Securities which may be purchased include 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 CMC in accordance with guidelines
established by the respective Boards of Trustees, of a quality equivalent to
securities so rated. The Trust and the Acquiring Fund may each also invest in
municipal bonds and participation interests therein, including industrial
development revenue bonds and pollution control revenue bonds, which have
remaining maturities of 397 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, have, in the opinion of CMC, determined in
accordance with guidelines established by the respective Boards of Trustees,
essentially the same characteristics and quality as
 
                                       10
<PAGE>   140
 
bonds being so rated. In addition, the Trust and the Acquiring Fund may purchase
other types of tax-exempt Municipal Securities such as short-term discount
notes. These investments must (1) be rated or are deemed to have been 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 CMC determined in
accordance with guidelines established by the respective Boards of Trustees.
 
Each of the Trust and the Acquiring Fund may invest in variable rate demand
municipal securities, loan participations and taxable money market securities,
purchase securities on a when-issued or delayed-delivery basis, may invest in
securities of other investment companies, may purchase taxable money market
securities and may enter into repurchase agreements.
 
INVESTMENT RESTRICTIONS
 
The fundamental investment restrictions of the Trust and the Acquiring Fund are
substantially identical except for the following differences:
 
(1) The Trust may not underwrite any securities issued by others. The Acquiring
Fund has a similar policy except that the Acquiring Fund may underwrite the
securities of others to the extent it may be deemed to be an underwriter under
certain securities laws in the disposition of "restricted securities."

    
(2) The Trust may not borrow money or enter into reverse repurchase agreements
except for temporary or emergency non-investment purposes, such as to
accommodate abnormally heavy redemption requests, and then only in an amount not
exceeding 5% of the value of the Trust's total assets at the time of borrowing.
The Acquiring Fund has a somewhat similar policy except its policy provides that
the Acquiring Fund may not borrow money or issue senior securities, except that
the Acquiring 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 the Acquiring Fund's total assets at the time of such borrowing
and except as permitted pursuant to an exemption from the 1940 Act. The
Acquiring Fund will not purchase securities while its borrowings (including
reverse repurchase agreements and dollar roll agreements) exceed 5% of its total
assets.
 
(3) The Trust may not purchase or retain securities of any issuer for the
Trust's portfolio if those officers and Trustees of the Trust or officers or
Directors of CMC, who individually own more than 1/2 of 1% of the outstanding
securities of such issuer, together beneficially own more than 5% of such
outstanding securities. The Acquiring Fund has no such policy.
 
(4) The Trust may not purchase or sell oil and gas interests. The Acquiring Fund
has a similar policy except that such policy also excludes purchases of
participations or other direct interests in other mineral exploration or
development programs.
 
(5) The Trust has the policy of not purchasing from or selling to any of its
officers or Trustees or the officers or Directors of CMC, portfolio securities
of the Trust. The Acquiring Fund has no such policy but is limited in its
ability to do so by the 1940 Act.
 
(6) The Trust may not invest in companies for the purposes of exercising control
or management of another company. The Acquiring Fund has no such policy.
    
 
In addition, the Acquiring Fund has the following non-fundamental investment
restrictions. Except as noted below, these non-fundamental investment
restrictions are substantially similar to fundamental investment restrictions of
the Trust. As discussed above, however, fundamental restrictions of a fund may
not be changed without a vote of a majority of the outstanding voting securities
of the fund; non-fundamental policies may be changed without a shareholder vote.
As a consequence, the following
 
                                       11
<PAGE>   141
 
policies could be modified, or eliminated, by the Group with respect to the
Acquiring Fund without shareholder approval.
 
(1) The Acquiring Fund may not engage in any short sales.
 
(2) The Acquiring Fund may not (a) purchase or otherwise acquire any securities,
if as a result, more than 10% of the Acquiring Fund's net assets would be
invested in securities that are illiquid or (b) invest more than 15% of the
Acquiring Fund's total assets in securities which are restricted as to
disposition. The Trust has a fundamental policy that provides that it may not
purchase securities subject to legal or contractual restrictions on the resale
thereof ("restricted securities") if such purchase would cause more than 10% of
the Trust's assets (including repurchase agreements maturing in more than seven
days) to be invested in restricted securities and other securities that are not
readily marketable.
 
(3) The Acquiring Fund may not 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.
 
PORTFOLIO MANAGERS. Since CMC serves as the investment adviser to both the Trust
and the Acquiring Fund, the person currently serving as portfolio manager for
the Trust intends to serve after the Reorganization as portfolio manager for the
Acquiring Fund.
 
It is not anticipated that the above-mentioned differences in investment
policies and restrictions will, individually or in the aggregate, result in an
appreciable variation between the level of investment risks associated with an
investment in the Trust. For a more complete description of the Acquiring Fund's
investment policies and restrictions, including relevant risk factors, see "WHAT
ARE THE INVESTMENT OBJECTIVES AND POLICIES OF THE FUND?" in the Acquiring Fund's
Prospectus and INVESTMENT OBJECTIVES AND POLICIES" in the Acquiring Fund's
Statement of Additional Information. For a more complete description of the
Trust's investment policies and restrictions, including relevant risk factors,
see "WHAT ARE THE INVESTMENT OBJECTIVES AND POLICIES OF THE TRUST?" in the
Trust's Prospectus and "INVESTMENT OBJECTIVES AND POLICIES" in the Trust's
Statement of Additional Information.

                                   THE TRUST
 
Pursuant to the laws of Ohio and the Trust's Declaration of Trust, the
responsibility for the management of the Trust is vested in its Board of
Trustees which, among other things, is empowered by the Trust's Declaration of
Trust to elect officers of the Trust and contract with and provide for the
compensation of agents, consultants, and other professionals to assist and
advise in such management.
 
   
INVESTMENT ADVISER. The Trust is advised by Cardinal Management Corp. ("CMC"),
155 East Broad Street, Columbus, Ohio 43215, a wholly owned subsidiary of The
Ohio Company. CMC is also the investment adviser and manager of each of the
other Cardinal Funds except The Cardinal Fund Inc. CMC was established as an
Ohio corporation on March 21, 1980, and has been providing investment advisory
services to open-end management investment companies like the Trust since 1980.
    
 
   
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

<PAGE>   142
 
In its capacity as investment adviser, and subject to the ultimate authority of
the Trust's Board of Trustees, CMC, in accordance with the Trust's investment
objectives and policies, manages the Trust, and makes decisions with respect to
and places orders for all purchases and sales of its portfolio securities. In
addition, pursuant to the Investment Advisory Agreement, CMC generally assists
in all aspects of the Trust's administration and operation. Since December 22,
1995, David C. Will has been primarily responsible for the day-to-day management
of the Trust's portfolio. Mr. Will has been a Vice President of The Ohio Company
and CMC since 1990 and has more than 25 years of investment management
experience.
 
For the services provided and expenses assumed pursuant to its investment
advisory agreement with the Trust, CMC receives a fee from the Trust, computed
daily and paid monthly at the annual rate of .50% of average net daily assets of
the Trust.
 
For a complete description of the Trust's advisory arrangements, see the section
in the Trust's Prospectus entitled "WHO MANAGES MY INVESTMENT IN THE
TRUST? -- Investment Adviser and Manager."
 
DISTRIBUTOR. The Trust has entered into a Distributor's Contract with The Ohio
Company, 155 East Broad Street, Columbus, Ohio 43215, pursuant to which Shares
of the Trust continuously are offered on a best efforts basis by The Ohio
Company and dealers selected by The Ohio Company. H. Keith Allen is an officer
and trustee/director of both the Trust, CMC and The Ohio Company. Frank W.
Siegel, an officer and trustee of the Trust, is an officer of The Ohio Company
and an officer and director of CMC. David C. Will and James M. Schrack II are
officers of both the Trust and The Ohio Company, and Mr. Will is an officer of
CMC. The Ohio Company receives no compensation from the Trust in connection with
its services under such Distributor's Contract.
 
DIVIDEND AND TRANSFER AGENT AND FUND ACCOUNTANT. CMC, 215 East Capital Street,
Columbus, Ohio 43215, serves as the Trust's Dividend and Transfer Agent. In
consideration of such services, the Trust has agreed to pay CMC an annual fee,
paid monthly, equal to $21 per shareholder account, plus out-of-pocket expenses.
 
In addition, CMC provides certain fund accounting services for the Trust. CMC
receives a fee from the Trust for such services equal to $9,000 for the first
$25 million of assets, $6,000 for the next $25 million of assets, $3,000 for
each additional $25 million to $350 million of assets, and $3,000 for each
additional $100 million of assets thereafter.
 
   
For a complete description of these arrangements and the other expenses borne by
the Trust, see the section in the Trust's Prospectus entitled "WHO MANAGES MY
INVESTMENT IN THE TRUST?"
    
 
CUSTODIAN. The Trust has appointed The Fifth Third Bank ("Fifth Third"), 38
Fountain Square Plaza, Cincinnati, Ohio 45263, as the Trust's custodian. In such

                               THE ACQUIRING FUND

Trust's distributor.

CERTAIN FINANCIAL INFORMATION. The Prospectus for the Trust contains information
on per share income, capital changes and performance calculations under the
caption "FINANCIAL HIGHLIGHTS."
 
The Acquiring Fund has not yet commenced operations and has no and will have no
assets or liabilities prior to the consummation of the Reorganization.
Therefore, no information regarding per share income and capital changes is
available. For information regarding performance calculations and comparisons,
see the information under the caption "PERFORMANCE INFORMATION" in the Acquiring
Fund's Prospectus.
 
COMPARISON OF RIGHTS OF SECURITY HOLDERS. The Trust is an Ohio business trust,
registered under the 1940 Act as an open-end investment company of the
management type. The Trust was established under a Declaration of Trust dated
January 13, 1983. The Group is an Ohio business trust, registered under the 1940
Act as an open-end investment company of the management type. The Group was
established under a Declaration of Trust dated as of March 23, 1993. Both the
Trust and the Group are authorized to issue an unlimited number of shares of
beneficial interest, and such shares may be divided into one or more series and
for the Group, separate classes of shares. The Acquiring Fund is one of six
series of the Group. The other five series of the Group are The Cardinal Fund,
Cardinal
 
                                       14
<PAGE>   144
 
Government Obligations Fund, Cardinal Government Securities Money Market Fund,
Cardinal Balanced Fund and Cardinal Aggressive Growth Fund.
 
Each Share of the Trust represents an equal proportionate interest in the Trust
with each other share. Shares are entitled upon liquidation to a pro rata share
of the net assets of the Trust. Shares of the Trust issued pursuant to the
Trust's Declaration of Trust are fully paid and nonassessable and have no
preemptive rights or other preferences, appraisal or conversion rights except to
the extent set by the Trustees.
 
Shares of the Acquiring Fund, once properly issued and outstanding, are fully
paid and nonassessable and have no preference as to conversion, exchange,
dividends, retirement or other features, and have no preemptive or appraisal
rights.
 
Shareholders of the Trust are entitled to one vote for each full Share held and
a proportionate fractional vote for each fractional Share held. Shareholders of
the Acquiring Fund are entitled to one vote for each dollar of value invested
and a proportionate fractional vote for any fraction of a dollar invested.
 
Voting rights are not cumulative, so that the holders of more than 50% of the
Trust voting in the election of its Trustees have the power to elect all of the
Trustees of the Trust. The Trust currently holds an annual meeting of
shareholders.
 
Shareholders of the Group have no cumulative voting rights, which means that the
holders of a plurality of the shares voting for the election of the Group's
Board of Trustees can elect all of the Group's Board of Trustees if they choose
to do so. The Group does not intend to hold annual meetings of shareholders,
except as required under its Declaration of Trust or the 1940 Act. Shareholders
of the Acquiring Fund will vote in the aggregate with other shareholders of the
Group and not by series or portfolio except as otherwise expressly required by
law. For example, shareholders of the Acquiring 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 Acquiring 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 Acquiring Fund's investment advisory agreement or any of the Acquiring
Fund's fundamental policies.
 
Therefore, after the Reorganization, shareholders of the Acquiring Fund alone
will not be able to elect the Trustees of the Group or ratify the selection of
independent accountants but will vote with all the other shareholders of the
Group on such issues if and when presented to shareholders. In addition,
shareholders of the Group receive one vote for each dollar of value invested;
therefore, a shareholder of one share of the Acquiring Fund will receive one
vote for such share while a shareholder of one share of another non-money market
fund of the Group will receive more than one vote for such share, e.g., a share
of Cardinal Balanced Fund with a net asset value of $9.50 will be entitled to
9.5 votes. In addition, the Group currently does not intend to hold annual
meetings unless otherwise required to do so. Therefore, it can not be determined
when shareholders of the Acquiring Fund will next be entitled to vote for the
election of Trustees or the ratification of the selection of independent public
accountants.

THE TRUST'S BOARD OF TRUSTEES AND MANAGEMENT RECOMMEND APPROVAL OF THE PLAN.
 
   
    FIXING THE NUMBER OF TRUSTEES AND ELECTION OF TRUSTEES -- ISSUES 2 AND 3
    
 
   
It is the present intention that the enclosed proxy will be used for the
purposes of voting in favor of fixing the number of trustees at ten and the
election of each of the following ten nominees as a trustee to hold office until
the next annual meeting and until his successor is elected and qualified. Each
of the nominees is a member of the present Board of Trustees of the Trust and,
except for Mr. Allen, each has been elected by shareholder vote. Pursuant to
Rule 14a-4(d) under the Securities Exchange Act of 1934, each nominee has
consented to be named in this Combined Prospectus/Proxy Statement and to serve
if elected. It is not expected that any of the nominees will decline or become
unavailable for election, but in case this should happen, the discretionary
power given in the proxy may be used to vote for a substitute nominee or
nominees.

              AGREEMENT AND PLAN OF REORGANIZATION AND LIQUIDATION
 
Agreement and Plan of Reorganization and Liquidation ("Agreement") dated as of
December 1, 1995, by and between The Cardinal Group, an Ohio business trust
("TCG"), and Cardinal Tax Exempt Money Trust, an Ohio business trust ("CTEMT").
 
WHEREAS, TCG is registered under the Investment Company Act of 1940, as amended
("1940 Act"), as an open-end investment company of the management type and has,
or before the Exchange Date (as defined below) is expected to have, issued and
outstanding one class of shares of beneficial interest, without par value
("Shares"), for each of six series, one such series being Cardinal Tax Exempt
Money Market Fund (hereinafter sometimes referred to as the "Cardinal Tax Exempt
Money Market Fund" or the "Acquiring Series"); and
 
WHEREAS, CTEMT is registered under the 1940 Act as an open-end investment
company of the management type and currently has issued and outstanding one
class of shares of beneficial interest, par value $.10 per share; and
 
WHEREAS, CTEMT plans to transfer all of its assets, and to assign all of its
liabilities, to the Acquiring Series, in exchange for Shares of the Acquiring
Series (the "Acquiring Series Shares"), followed by the distribution of the
Acquiring Series Shares by CTEMT to its shareholders, and followed by the
dissolution of CTEMT, all upon the terms and provisions of this Agreement (the
"Reorganization"); and
 
WHEREAS, this Agreement is intended to be and is adopted as a plan of
reorganization and liquidation within the meaning of Section 368(a) of the
United States Internal Revenue Code of 1986, as amended (the "Code"); and
 
WHEREAS, the trustees of TCG have determined that the Reorganization is in the
best interests of TCG, and that the interests of its shareholders will not be
diluted as a result thereof; and
 
WHEREAS, the trustees of CTEMT have determined that the Reorganization is in the
best interests of CTEMT and that the interests of its shareholders will not be
diluted as a result thereof;
 
NOW, THEREFORE, in consideration of the mutual promises herein contained, the
parties hereto covenant and agree as follows:
 
(1) PLAN OF REORGANIZATION AND LIQUIDATION.
 
(a) Sale of Assets, Assumption of Liabilities. Subject to the prior approval of
shareholders of CTEMT and to the other terms and conditions contained herein
(including the obligation of CTEMT to distribute to its shareholders all of its
investment company taxable income and net capital gain as described in Section
8(i) herein), CTEMT agrees to sell, assign, convey, transfer and deliver to the
Acquiring Series, and the Acquiring Series agrees to acquire from CTEMT on the
Exchange Date (as defined below), all of the Investments (as defined below),
cash and other assets of CTEMT in exchange for that number of full and
fractional Acquiring Series Shares of the Acquiring Series having an aggregate
net asset value equal to the value of all assets of CTEMT transferred to the
Acquiring Series, as provided in Section 4, less the liabilities of CTEMT
assumed by the Acquiring Series.
 
(b) Assets Acquired. The assets to be acquired by the Acquiring Series from
CTEMT shall consist of all of CTEMT's property, including, without limitation,
all Investments, cash and dividends or interest receivables which are owned by
CTEMT and any deferred or prepaid expenses shown as an asset on the books of
CTEMT as of the Valuation Time described in Section 4.
 
(c) Liabilities Assumed. Prior to the Exchange Date CTEMT will endeavor to
discharge or cause to be discharged, or make provision for the payment of, all
of its known liabilities and obligations. The Acquiring Series shall assume all
liabilities, expenses, costs, charges and reserves of CTEMT, contin-
 
                                       A-1
<PAGE>   152
 
gent or otherwise, including liabilities reflected in the unaudited statement of
assets and liabilities of CTEMT as of the Valuation Time, prepared by or on
behalf of CTEMT in accordance with generally accepted accounting principles
consistently applied from and after September 30, 1995.
 
(d) Liquidation and Dissolution. Upon consummation of the transactions described
in Section 1(a), 1(b) and 1(c) above, CTEMT shall distribute in complete
liquidation to its shareholders of record as of the Exchange Date the Acquiring
Series Shares received by it, each CTEMT shareholder of record being entitled to
receive that number of Acquiring Series Shares equal to the proportion which the
number of shares of beneficial interest, par value $.10 per share, of CTEMT held
by such shareholder bears to the total number of such shares of CTEMT
outstanding on such date, and shall take such further action as may be required,
necessary or appropriate under CTEMT's Declaration of Trust, Ohio law and the
Code to effect the complete liquidation and dissolution of CTEMT. CTEMT will
fulfill all reporting requirements under the 1940 Act, both before and after the
Reorganization.
 
(2) REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF CTEMT. CTEMT represents and
warrants to and agrees with TCG and the Acquiring Series that:
 
(a) CTEMT is a business trust validly existing under the laws of the State of
Ohio and has power to own all of its properties and assets and to carry out its

trust in each jurisdiction where the ownership of its property and the conduct
of its business require qualification. CTEMT has all necessary federal, state
and local authorizations to carry on its business as now being conducted and to
fulfill the terms of this Agreement, except as set forth in Section 2(l).
 
(b) CTEMT is registered under the 1940 Act as an open-end investment company of

accepted accounting principles, and there are no known material liabilities of
CTEMT as of such dates which are not disclosed therein.

hereof contain any 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.
 
(e) Except as may have been previously disclosed to TCG, there are no material
legal, administrative or other proceedings pending or, to the knowledge of
CTEMT, threatened against CTEMT.

(i) CTEMT has filed or will file all federal and state tax returns which, to the
knowledge of CTEMT's officers, are required to be filed by CTEMT and has paid or
will pay all federal and state taxes shown to be due on said returns or on any
assessments received by CTEMT. All tax liabilities of CTEMT have been adequately

liabilities as contemplated by this Agreement, TCG and the Acquiring Series will

Act and 1940 Act and assuming due authorization, execution and delivery of this
Agreement by TCG, is a valid and binding obligation of CTEMT, enforceable in

be the same as the basis of his or her shares exchanged therefor; (v) a CTEMT

Acquiring Series will be the same as the basis of the assets in the hands of
CTEMT immediately prior to the transfer; and (viii) the Acquiring Series'

                             PROSPECTUS HIGHLIGHTS
 
INVESTMENT OBJECTIVES.........   The Fund seeks long-term growth of capital and
                                 income. Current income is a secondary
                                 objective. (See page 4.)
 
INVESTMENT POLICIES...........   The Fund generally invests in equity securities
                                 which are growth oriented. Current income,
                                 while a factor in portfolio selection, is
                                 secondary to the primary objective. (See pages
                                 4 and 5.)
 
DIVIDENDS.....................   Dividends and capital gains distributions are
                                 made with such frequency as the Group shall
                                 determine. Generally, dividends are declared
                                 quarterly and long-term capital gains, if any,
                                 are declared annually. Such dividends and
                                 distributions may be invested in additional
                                 Shares of the Fund at no charge. (See page 11.)
 
PURCHASES.....................   There is a minimum initial investment of $1,000
                                 with subsequent minimums of $50. (See page 8.)
                                 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 8) and waived for
                                 certain purchasers for whom The Ohio Company
                                 serves as a trustee or investment adviser. (See
                                 page 9.)
 
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
                                 11.)
 
INVESTMENT ADVISER AND
  MANAGER.....................   Cardinal Management Corp. (the "Adviser"), a
                                 wholly-owned subsidiary of The Ohio Company, is
                                 the Fund's investment adviser. The Adviser also
                                 serves as investment adviser for Cardinal
                                 Government Obligations Fund, Cardinal
                                 Government Securities Money Market Fund,
                                 Cardinal Tax Exempt Money Market Fund, Cardinal
                                 Balanced Fund and Cardinal Aggressive Growth
                                 Fund (collectively, with the Fund, the
                                 "Cardinal Funds"). (See page 16.)
 
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

                            PERFORMANCE INFORMATION
 
     From time to time the Fund may advertise its average annual total return
and cumulative return. SUCH RETURN 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. 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
(currently 4.5%) 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 is
deducted from the initial investment. If the sales charge were not deducted, the
average annual total return and cumulative return advertised would be higher.
 
     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., 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.
 
                               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 has
been organized for the purpose of acquiring all of the assets and liabilities of
The Cardinal Fund Inc. ("TCFI") to effect a reorganization of TCFI from a stand
alone investment company to a separate series of the Group (the
"Reorganization").
 
                       WHAT ARE THE INVESTMENT OBJECTIVES
                           AND POLICIES OF THE FUND?
 
IN GENERAL
 
     The investment objectives of the Fund are to achieve long-term growth of
capital and income. Current income is a secondary objective. The Fund seeks to
achieve its objectives through selective participation in the long-term progress
of businesses and industries. The investment objectives with respect to the Fund
are a fundamental policy and as such may not be changed without a vote of the
holders of a majority of the outstanding Shares of the Fund (as defined below
under "WHAT ARE MY RIGHTS AS A SHAREHOLDER?"). The Fund is not intended to
provide a complete and balanced investment program for an investor. There can be
no assurance that the investment objectives of the Fund will be achieved.
 
     The policy of the 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 Fund are traded in either established
over-the-counter markets or on national exchanges and are issued by companies
 
                                        4
<PAGE>   6
 
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 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 Fund's equity position should be reduced. At
such times, and otherwise for cash management purposes, the 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.
 
RISK FACTORS AND INVESTMENT TECHNIQUES
 
     GENERAL.  Like any investment program, an investment in the Fund entails
certain risks. As a fund investing primarily in common stocks, the Fund is
subject to stock market risk, i.e., the possibility that stock prices in general
will decline over short or even extended periods.
 
     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.
 
     FOREIGN SECURITIES.  The 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"). Unsponsored ADRs may be less liquid than sponsored
ADRs, and there may be less information available regarding the underlying
foreign issuer for unsponsored ADRs. 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. 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. The Fund will acquire securities
issued by foreign issuers only when the Adviser believes that the risks
associated with such investments are minimal.
 
     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
 
                                        5
<PAGE>   7
 
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 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.
 
                                        6
<PAGE>   8
 
     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 investment 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.
 
          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.
 
                                        7
<PAGE>   9
 
          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 may 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 SHARES OF THE FUND?
 
GENERAL
 
     The Fund's Shares may be purchased at the public offering price, as
described below under "Public Offering Price," through The Ohio Company,
principal underwriter of the Fund's 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 Shares of the 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, Shares may also be purchased by wiring funds
to the Fund's custodian. Prior to wiring any such funds and to 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 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 Shares owned by you and
the number of Shares being held in safekeeping by Cardinal Management Corp., as
the Fund's transfer agent (the "Transfer Agent"), for your account. Certificates
representing Shares will not be issued.
 
PUBLIC OFFERING PRICE
 
     The public offering price of Shares of the 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:

     (See "HOW IS NET ASSET VALUE CALCULATED?" for a description of the
computation of net asset value per share.)
 
     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, (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, or (3) accounts with respect to which The
Ohio Company serves either as a trustee or as investment adviser.
 
     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 Shares of the 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.
 
                        MAY MY TAX SHELTERED RETIREMENT
                            PLAN INVEST IN THE FUND?
 
     Shares of the Fund qualify for purchase in connection with the following
tax sheltered retirement plans:
 
     -- Individual retirement account ("IRAs") plans
 
     -- Simplified Employee Pension Plans
 
     -- 403(b)(7) Custodial Plans sponsored by certain tax-exempt employers
 
     -- Pension, profit-sharing and 401(k) plans qualifying under Section 401(a)
        of the Internal Revenue Code

<PAGE>   11
 
                   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 Shares of the Fund and 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 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. 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 Shares actually purchased. If the full
amount indicated is not purchased, such escrowed Shares will be involuntarily
redeemed to pay the additional sales charge, if necessary. Dividends on escrowed
Shares, whether paid in cash or reinvested in additional Shares of the
applicable Cardinal Load Fund, are not subject to escrow. The escrowed 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 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 Shares of the Fund and of one or more of
the other Cardinal Load Funds. For example, if you concurrently purchase Shares
of the Fund at the total public offering price of $50,000 and shares of another
Cardinal Load Fund at the total public offering price of $50,000, the sales
charge 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 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 Shares you may also be eligible to pay a
reduced sales charge for your subsequent purchases of Shares where the total
public offering price of Shares then being purchased plus the then aggregate
current net asset value of Shares of the Fund and of shares of any Cardinal Load
Fund held in your account equals $100,000 or more. You would be able to purchase
Shares at the public offering price applicable to the total of (a) the total
public offering price of the Shares of the Fund then being purchased plus (b)
the then current net asset value of Shares of the Fund and of shares of any
other Cardinal Load Fund held in your account. For purposes of determining the
aggregate current net asset value of Shares held in your account, you may
include Shares then owned by your spouse and children not of legal age.
 
                                       10
<PAGE>   12
 
     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 from net income and
net realized capital gains of the Fund. It is the policy of the 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 Shares of the
Fund and not in cash. Dividends are paid in cash not later than seven days after
a shareholder's complete redemption of his Shares in the Fund.
 
     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 SHARES?
 
     Investors may redeem Shares of the 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 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 Shares and may charge a
fee for such services.
 
     The Group will make payment for redeemed 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 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 intends to pay cash for all Shares redeemed, but, under abnormal
conditions which make payment in cash unwise, the Group may make payment wholly
or partly in 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 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 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
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 Shares of the Fund having a total value of $10,000
or more at the current net asset value, you may elect to redeem your 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.
 
                 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 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 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 Shares of the Fund for shares of:
 
           Cardinal Aggressive Growth Fund,
           an equity fund seeking appreciation of
           capital (upon the payment of the applicable sales charge);
 
           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);
 
           Cardinal Government Obligations Fund,
           a fund investing in securities issued
           or guaranteed by the U.S. Government
           (upon the payment of the applicable sales charge);
 
           Cardinal Government Securities Money Market Fund,
           a U.S. Government securities money market fund
           (without payment of any sales charge); or
 
           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 Fund Shares, for whom the
sales charge has been waived, for shares of a Cardinal Load Fund may be
completed without the payment of a sales charge, and (ii) exchanges of Fund
Shares by all other shareholders for 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 shares of such Cardinal Load
Fund and the sales charge previously paid on the Fund 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 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 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.
 
     For tax purposes, an exchange is treated as a redemption and a new
purchase. However, a shareholder may not include any sales charge on Shares of
the Fund for purposes of calculating the gain or loss realized upon an exchange
of those 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 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) minus all liabilities
(including estimated accrued expenses) by the total number of Shares then
outstanding.
 
     The net asset value per share will fluctuate as the value of the investment
portfolio of the 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 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.
 
                     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.
 
                              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
 
                                       14
<PAGE>   16
 
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 the Fund bear to its gross income.
 
     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.
 
     Foreign taxes may be imposed on the Fund by foreign countries with respect
to its income from foreign securities. Since less than 50% in value of the
Fund's total assets at the end of its fiscal year are expected to be invested in
stock or securities of foreign corporations, the Fund will not be entitled under
the Code to pass through to its shareholders their pro rata share of the foreign
taxes paid by the Fund. These taxes will be taken as a deduction by the Fund.
 
     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, who are
elected by the shareholders of the Group's funds and who 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. The Ohio
Company receives no fees under its Distribution Agreement with the Group but may
retain all or a portion of the sales charge and may receive fees under the
Distribution Plan discussed below.
 
                                       15

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 a voting stock, may be considered controlling persons of The Ohio
Company. The Ohio Company serves as principal underwriter for each of the
Cardinal Funds and for TCFI and serves as the investment adviser of TCFI.
 
     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 December 22, 1995, John Bevilacqua has been primarily
responsible for the day-to-day management of the portfolio of TCFI (the Fund's
predecessor). It is expected that, upon consummation of the Reorganization, Mr.
Bevilacqua will be the portfolio manager for the Fund. 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. 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 .60%
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 return 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 $18 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.
 
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.
 
                                       16

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 Fund will bear the following expenses relating to
its operations: organizational expenses, taxes, interest, any brokerage fees and
commissions, fees and expenses of the Trustees of the Group, Commission fees,
state securities qualification fees, costs of preparing and printing
prospectuses for regulatory purposes and for distribution to the Fund's current
shareholders, outside auditing and legal expenses, advisory fees, fund
accounting fees, fees and out-of-pocket expenses of the custodian and Transfer
Agent, costs for independent pricing services, certain insurance premiums, costs
of maintenance of the Group's existence, costs of shareholders' reports and
meetings, distribution expenses incurred pursuant to the Distribution and
Shareholder Service Plan described below, and any extraordinary expenses
incurred in the Fund's operation.
 
DISTRIBUTION PLAN
 
     Pursuant to Rule 12b-1 under the 1940 Act, the Group has adopted a
Distribution and Shareholder Service Plan (the "Plan"), under which 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
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 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 Shares of the Fund
purchased and held by The Ohio Company for the accounts of its customers and
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 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 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
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, each having its own class of shares. The
other funds of the Group are Cardinal Balanced Fund, Cardinal Aggressive Growth
Fund, Cardinal Government Obligations Fund, Cardinal Government Securities Money
Market Fund and Cardinal Tax Exempt Money Market Fund. 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 Fund's
investment advisory agreement, the Plan 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 and may be
removed by the Board of Trustees or shareholders in accordance with the
provisions of the Declaration of Trust and By-Laws of the Group and 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
 
                                       18
<PAGE>   20
 
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.

PROSPECTUS
 
                      CARDINAL GOVERNMENT OBLIGATIONS FUND
 
     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'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 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.

                             PROSPECTUS HIGHLIGHTS
 
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 page 5.)
 
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 5 and 6.)
 
CURRENT INCOME................   Dividends are declared daily and distributions
                                 are generally made monthly as the Fund shall
                                 determine. Long-term capital gains, if any, are
                                 distributed annually. (See page 13.)
 
PURCHASES.....................   There is a minimum initial investment of $1,000
                                 with subsequent minimums of $50. (See page 10.)
                                 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 10) and waived for
                                 certain purchasers for whom The Ohio Company
                                 serves as a trustee or investment adviser. (See
                                 page 11.)
 
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
                                 13.)
 
INVESTMENT ADVISER AND
  MANAGER.....................   Cardinal Management Corp. (the "Adviser"), a
                                 wholly-owned subsidiary of The Ohio Company, is
                                 the Fund's investment adviser. The Adviser also
                                 serves as investment adviser for The Cardinal

                                 Fund, the "Cardinal Funds"). (See page 17.)
 
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

                            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. 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 (currently 4.5%) 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 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 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., 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.
 
                               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 has
been organized for the purpose of acquiring all of the assets and liabilities of
Cardinal Government Obligations Fund ("CGOF") to effect a reorganization of CGOF
from a stand-alone investment company to a separate series of the Group (the
"Reorganization").
 
     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.
 
                                        4

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 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
 
                                        5
<PAGE>   31
 
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.
 
     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.
 
                                        6
<PAGE>   32
 
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 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
 
                                        7
<PAGE>   33
 
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 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
 
                                        8

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.
 
          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.
 
                                        9
<PAGE>   35
 
     The following additional investment restriction may be changed without the
vote of a majority of the outstanding Shares of the Fund. The Fund may 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 SHARES OF THE FUND?
 
GENERAL
 
     The Fund's Shares may be purchased at the public offering price, as
described below under "Public Offering Price," through The Ohio Company,
principal underwriter of the Fund's 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 Shares of the 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, Shares may also be purchased by wiring funds
to the Fund's custodian. Prior to wiring any such funds and to 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 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 Shares owned by you and
the number of Shares being held in safekeeping by Cardinal Management Corp., as
the Fund's transfer agent (the "Transfer Agent"), for your account. Certificates
representing Shares will not be issued.
 
PUBLIC OFFERING PRICE
 
     The public offering price of Shares of the 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:

     (See "HOW IS NET ASSET VALUE CALCULATED?" for a description of the
computation of net asset value per share.)
 
     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.
 
                                       10
<PAGE>   36
 
     No sales charge is imposed on purchases of Shares by (1) officers,
trustees, and employees of the Group, (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, or (3) accounts with respect to which The
Ohio Company serves either as a trustee or as investment adviser.
 
     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 Shares of the 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.
 
                        MAY MY TAX SHELTERED RETIREMENT
                            PLAN INVEST IN THE FUND?
 
     Shares of the Fund qualify for purchase in connection with the following
tax sheltered retirement plans:
 
     -- Individual retirement account ("IRAs") plans
 
     -- Simplified Employee Pension Plans
 
     -- 403(b)(7) Custodial Plans sponsored by certain tax-exempt employers
 
     -- Pension, profit-sharing and 401(k) plans qualifying under Section 401(a)
        of the Internal Revenue Code
 
                   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 Shares of the Fund and 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 Shares to be so
purchased. The 13-month period during which the Letter of Intention is in effect
will begin
 
                                       11
<PAGE>   37
 
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. 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 Shares actually purchased. If the full
amount indicated is not purchased, such escrowed Shares will be involuntarily
redeemed to pay the additional sales charge, if necessary. Dividends on escrowed
Shares, whether paid in cash or reinvested in additional Shares of the
applicable Cardinal Load Fund, are not subject to escrow. The escrowed 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 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 Shares of the Fund and of one or more of
the other Cardinal Load Funds. For example, if you concurrently purchase Shares
of the Fund at the total public offering price of $50,000 and shares of another
Cardinal Load Fund at the total public offering price of $50,000, the sales
charge 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 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 Shares you may also be eligible to pay a
reduced sales charge for your subsequent purchases of Shares where the total
public offering price of Shares then being purchased plus the then aggregate
current net asset value of Shares of the Fund and of shares of any Cardinal Load
Fund held in your account equals $100,000 or more. You would be able to purchase
Shares at the public offering price applicable to the total of (a) the total
public offering price of the Shares of the Fund then being purchased plus (b)
the then current net asset value of Shares of the Fund and of shares of any
other Cardinal Load Fund held in your account. For purposes of determining the
aggregate current net asset value of Shares held in your account, you may
include 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 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 Shares in
the Fund.
 
     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 SHARES?
 
     Investors may redeem Shares of the 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 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 Shares and may charge a
fee for such services.
 
     The Group will make payment for redeemed 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 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 intends to pay cash for all Shares redeemed, but, under abnormal
conditions which make payment in cash unwise, the Group may make payment wholly
or partly in 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 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.
 
                                       13
<PAGE>   39
 
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 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
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 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 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.
 
                 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 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 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 Shares of the Fund for shares of:
 
           Cardinal Aggressive Growth Fund,
           an equity fund seeking appreciation of
           capital (upon the payment of the applicable sales charge);
 
                                       14
<PAGE>   40
 
           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);
 
           The Cardinal Fund,
           an equity fund seeking long-term growth
           of capital and income (upon the payment of
           the applicable sales charge);
 
           Cardinal Government Securities Money Market Fund,
           a U.S. Government securities money market fund
           (without payment of any sales charge); or
 
           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 Fund Shares, for whom the
sales charge has been waived, for shares of a Cardinal Load Fund may be
completed without the payment of a sales charge, and (ii) exchanges of Fund
Shares by all other shareholders for 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 shares of such Cardinal Load
Fund and the sales charge previously paid on the Fund 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 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 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.
 
     For tax purposes, an exchange is treated as a redemption and a new
purchase. However, a shareholder may not include any sales charge on Shares of
the Fund for purposes of calculating the gain or loss realized upon an exchange
of those 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 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) minus all liabilities
(including estimated accrued expenses) by the total number of Shares then
outstanding.
 
                                       15
<PAGE>   41
 
     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.
 
                              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
 
                                       16
<PAGE>   42
 
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, who are
elected by the shareholders of the Group's funds and who 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. The Ohio
Company receives no fees under its Distribution Agreement with the Group but may
retain all or a portion of the sales charge and may receive 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 the Fund. The Adviser is also the investment adviser and
manager of each of the other Cardinal Funds and for CGOF.
 
     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 a voting stock, may be considered controlling persons of The Ohio
Company. The Ohio Company serves as principal underwriter for each of the
Cardinal Funds and for CGOF.
 
     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), 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
 
                                       17
<PAGE>   43
 
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.
 
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 Fund will bear the following expenses relating to
its operations: organizational expenses, taxes, interest, any brokerage fees and
commissions, fees and expenses of the Trustees of the Group, Commission fees,
state securities qualification fees, costs of preparing and printing
prospectuses for regulatory purposes and for distribution to the Fund's current
shareholders, outside auditing and legal expenses, advisory fees, fees and
out-of-pocket expenses of the custodian and Transfer Agent, costs for
independent pricing services, certain insurance premiums, costs of maintenance
of the Group's existence, costs of shareholders' reports and meetings,
distribution expenses incurred pursuant to the Distribution and Shareholder
Service Plan described below, and any extraordinary expenses incurred in the
Fund's operation.
 
DISTRIBUTION PLAN
 
     Pursuant to Rule 12b-1 under the 1940 Act, the Group has adopted a
Distribution and Shareholder Service Plan (the "Plan"), under which 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
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 Fund to be higher than it would
otherwise be absent such a waiver.
 
                                       18
<PAGE>   44
 
     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 Shares of the Fund
purchased and held by The Ohio Company for the accounts of its customers and
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 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 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
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, each having its own class of shares. The
other funds of the Group are Cardinal Balanced Fund, Cardinal Aggressive Growth
Fund, The Cardinal Fund, Cardinal Government Securities Money Market Fund and
Cardinal Tax Exempt Money Market Fund. 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 Fund's
investment advisory agreement, the Plan 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 and may be
removed by the Board of Trustees or shareholders in accordance with the
provisions of the Declaration of Trust and By-Laws of the Group and 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.
 
                                       19
<PAGE>   45
 
     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.

                            PERFORMANCE INFORMATION
 
     From time to time the Fund may advertise its "yield" or "annualized yield"
and its "effective yield". BOTH YIELD FIGURES ARE BASED ON HISTORICAL EARNINGS
AND ARE NOT INTENDED TO INDICATE FUTURE PERFORMANCE. The "yield" or "annualized
yield" of the 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.
 
     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., Morningstar, Inc. and CDA Investment Technologies, 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 Fund that appears in a publication such as those mentioned
above may be included in advertisements and in reports to shareholders.
 
                               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 has
been organized for the purpose of acquiring all of the assets and liabilities of
Cardinal Government Securities Trust ("CGST") to effect a reorganization of CGST
from a stand alone investment company to a series of the Group (the
"Reorganization").
 
                       WHAT ARE THE INVESTMENT OBJECTIVES
                           AND POLICIES OF THE FUND?
 
IN GENERAL
 
     The investment objectives of the Fund are to maximize current income while
preserving capital and maintaining liquidity. The investment objectives with
respect to the Fund are a fundamental policy and as such may not be changed
without a vote of the holders 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 objectives of the Fund will be achieved.
 
     The 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 Fund will purchase only obligations which have, or are
deemed to have, maturities, from the date of purchase, of thirteen months 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.
 
                                        3
<PAGE>   53
 
     Notwithstanding any of the foregoing, the Fund, as a money market fund
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 the Fund
may not exceed 90 days.
 
     Subject to the foregoing limitations and in order to achieve its investment
objectives, the 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 maturities of one year or less; Treasury notes
have maturities of one to ten years and Treasury bonds generally have 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 Fund intends to invest in variable and floating rate
instruments whose market value, upon reset of the interest rate, will
approximate par value 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 Fund will invest in such
securities only when it is satisfied that the credit risk with respect to the
issuer is minimal.
 
RISK FACTORS AND INVESTMENT TECHNIQUES
 
     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
 
                                        4
<PAGE>   54
 
(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.
 
     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 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.
 
     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 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.
 
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.
 
          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
 
                                        5
<PAGE>   55
 
     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
     the Fund's 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, other than by entering into repurchase agreements to
     the extent allowed herein and through the purchase of other obligations in
     accordance with its investment objective and policies.
 
     The following additional investment restriction may be changed without the
vote of a majority of the outstanding Shares of the Fund.
 
     The Fund may not:
 
          1. Purchase 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 FUND?
 
GENERAL
 
     Shares of the Fund 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 Fund's 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 Fund 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 Fund 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 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, Shares may also be purchased by wiring funds
to the Fund's custodian, 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. The 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 the Fund's portfolio securities that
the Fund's net asset value might be materially affected by changes in the value
of the portfolio securities
 
                                        6
<PAGE>   56
 
("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 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 new transaction in
your account, which will also show the total number of Shares owned by you and
the number of Shares being held in safekeeping by Cardinal Management Corp., the
Fund's 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 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.
 
PURCHASE BY FEDERAL FUNDS WIRE
 
     Investments in Shares of the Fund 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 Fund (800) 282-9446, toll free,
prior to wire transfer of its 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: Cardinal Government Securities Fund
           [Include Fund Account Number and Name of Account Holder]
 
     Funds transmitted by wire will be invested in Shares of the 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.
 
                                        7
<PAGE>   57
 
PURCHASE BY MAIL
 
     Investment in Shares of the Fund may be made by mail by sending a check or
other negotiable bank draft payable to the order of "Cardinal Government
Securities Money Market Fund" together with, in the case of an initial purchase,
an Application Form to:
 
           Cardinal Government Securities Money Market 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 Fund
within one Business Day following receipt by The Ohio Company. Checks drawn on
non-member banks may take considerably longer. The Transfer Agent or the Group
will attempt to notify the investor upon receipt of the latter type of check as
to the possible delay and to arrange for a better means of transmittal of funds.
THE GROUP STRONGLY RECOMMENDS THAT INVESTORS OF SUBSTANTIAL AMOUNTS USE FEDERAL
FUNDS TO PURCHASE SHARES.
 
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 Shares of the 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.
 
                        MAY MY TAX SHELTERED RETIREMENT
                            PLAN INVEST IN THE FUND?
 
     Shares of the Fund qualify for purchase in connection with the following
tax sheltered retirement plans:
 
     -- Individual retirement account ("IRAs") plans
 
     -- Simplified Employee Pension Plans
 
     -- 403(b)(7) Custodial Plans sponsored by certain tax-exempt employers
 
     -- Pension, profit-sharing and 401(k) plans qualifying under Section 401(a)
        of the Internal Revenue Code
 
                       WHAT DISTRIBUTIONS WILL I RECEIVE?
 
     The Fund's net income is declared as a dividend and accrued on each
Business Day immediately prior to the determination of the 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 accrued discount earned and premium amortized), plus
realized net short-term capital gains (losses) due to portfolio transactions (if
any), less the accrued expenses of the Fund applicable to that dividend period.
The Fund does not expect to realize any long-term capital gains due to its
policy of investing in securities maturing in 13 months or less.
 
     All dividends of net income are credited to each shareholder's account
daily and automatically reinvested in additional Shares of the Fund at the net
asset value on the last Business Day of each month. Shareholders, however, may
elect to receive monthly the dividends of $10 or more declared
 
                                        8
<PAGE>   58
 
on their Shares in cash by checking the appropriate box on the Account
Information Form or by otherwise notifying the Transfer Agent in writing. 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 the 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 the Fund's net asset
value per share were reduced, or expected to be reduced, below $1.00, the
Trustees might suspend further dividend accruals until the net asset value
returned to $1.00. Thus, extraordinary expenses, losses or depreciation may
result in no dividends being accrued for the period during which an investor
holds Shares as well as a redemption price lower than the purchase price for
such Shares.
 
                          HOW MAY I REDEEM MY SHARES?
 
     Investors may redeem Shares of the 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 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 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 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
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 Fund 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 Fund 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 Fund's 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 Fund 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 Fund'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 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 not less than $250. 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 the 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 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 Fund
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 Fund offers 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 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 Shares of the Fund for shares of:
 
           Cardinal Aggressive Growth Fund,
           an equity fund seeking appreciation of
           capital (upon the payment of the applicable sales charge);
 
           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);
 
           The Cardinal Fund,
           an equity fund seeking long-term growth of capital and
           income (upon the payment of the applicable sales charge);
 
           Cardinal Government Obligations Fund,
           a fund investing in securities issued
           or guaranteed by the U.S. Government
           (upon the payment of the applicable sales charge); or
 
           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, exchanges of Fund Shares for 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 shares of that Cardinal Load Fund. If, however, the Shares of
Fund to be exchanged were acquired as a result of an exchange of shares of the
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
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 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.
 
     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>   62
 
                       HOW IS NET ASSET VALUE CALCULATED?
 
     The Fund's 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 the Fund, less its liabilities, by the
total number of Shares outstanding. Expenses and fees of the Fund, 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 the Fund to use its
best efforts, under normal circumstances, to maintain a constant net asset value
of $1.00 per share. The 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. The 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.
 
                     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 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. 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.
 
                              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. The 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 Fund were to realize any long-term
capital gains, distribution by the 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 Fund may be subject to state and local taxes with respect to their ownership
of Fund Shares or distributions from the Fund.
 
                                       13
<PAGE>   63
 
     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, who are
elected by the shareholders of the Group's funds and who 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. The Ohio
Company receives no fees under its Distribution Agreement with the Group.
 
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 and for CGST.
 
     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 a voting stock, may be considered controlling persons of The Ohio
Company. The Ohio Company serves as principal underwriter for each of the
Cardinal Funds and for CGST.
 
     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 December 22, 1995, John R. Carle has been primarily
responsible for the day-to-day management of the portfolio of CGST (the Fund's
predecessor). 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 and has more than 28
years of management experience. 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 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 distributions 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 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.
 
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 Fund will bear the following expenses relating to
its operations: organizational expenses, taxes, interest, any brokerage fees and
commissions, fees and expenses of the Trustees of the Group, Commission fees,
state securities qualification fees, costs of preparing and printing
prospectuses for regulatory purposes and for distribution to the Fund's current
shareholders, outside auditing and legal expenses, advisory fees, fees and
out-of-pocket expenses of the custodian and Transfer Agent, costs for
independent pricing services, certain insurance premiums, costs of maintenance
of the Group's existence, costs of shareholders' reports and meetings, and any
extraordinary expenses incurred in the Fund's operation.
 
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, each having its own class of shares. The
other funds of the Group are The Cardinal Fund, Cardinal Government Obligations
Fund, Cardinal Tax Exempt Money Market Fund, Cardinal Balanced Fund and Cardinal
Aggressive Growth Fund. 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
 
                                       15
<PAGE>   65
 
as a fund, and not in the aggregate with other shareholders of the Group, for
purposes of approval of amendments to the Fund's investment advisory agreement
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 and may be
removed by the Board of Trustees or shareholders in accordance with the
provisions of the Declaration of Trust and By-Laws of the Group and 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 TAX EXEMPT MONEY MARKET FUND
 
     Cardinal Tax Exempt Money Market 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

     The Fund's investment objectives are maximizing current income exempt from
federal income tax while preserving capital and maintaining liquidity. The Fund
seeks to attain its objective 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 the Fund
will mature, or be deemed to mature, in 397 days (13 months) or less or will
have interest rates adjusted in accordance with established indexes (e.g., the
prime rate) not less frequently than semi-annually. There can be no assurance
that the Fund's objectives will be achieved.
 
     The Fund is designed for investors who desire current income exempt from
federal income tax that reflects prevailing interest rates for short-term
tax-exempt investments together with a high degree of liquidity.
 
     THE SHARES OF THE FUND 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 THE FUND
INVOLVES CERTAIN INVESTMENT RISKS, INCLUDING THE POSSIBLE LOSS OF PRINCIPAL. THE
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 the Fund may advertise its "yield" or "annualized yield,"
its "effective yield," 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
the 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-equivalent yield" demonstrates the taxable yield
necessary to produce an after-tax yield equivalent to that of the 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 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 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., Morningstar, Inc. and CDA Investment Technologies, 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 Fund that appears in a publication such as those mentioned
above may be included in advertisements and in reports to shareholders.
 
                               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 has
been organized for the purpose of acquiring all of the assets and liabilities of
Cardinal Tax Exempt Money Trust ("CTEMT") to effect a reorganization of CTEMT
from a stand-alone investment company to a separate series of the Group (the
"Reorganization").
 
                       WHAT ARE THE INVESTMENT OBJECTIVES
                           AND POLICIES OF THE FUND?
 
IN GENERAL
 
     The investment objectives of the Fund is to maximize current income exempt
from federal income tax while preserving capital and maintaining liquidity. The
investment objectives with respect to the Fund are a fundamental policy and as
such may not be changed without a vote of the holders of a majority of the
outstanding Shares of the Fund.
 
     As a money market fund, the Fund invests 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
 
                                        3
<PAGE>   73
 
or, if unrated, are of comparable quality. All securities or instruments in
which the Fund invests have, or are deemed to have, remaining maturities of 397
calendar days (thirteen months) or less. The dollar-weighted average maturity of
the obligations in the Fund will not exceed 90 days.
 
     As a matter of policy, under normal market conditions, the 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 objective, the 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 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 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 Fund may purchase other
types of tax-exempt Municipal Securities such as short-term discount 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 Fund's 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.  CTEMT, as the Fund's predecessor, has invested
and the Fund 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 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 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 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 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
Fund can be maintained at $1.00 per share
 
                                        4
<PAGE>   74
 
while the highest possible yield can be returned to investors. To the extent the
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 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 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 Trust invests may be
supported by bank letters of credit or comparable guarantees of financial
institutions. To the extent that 25% or more of the Trust's assets are invested
in variable rate demand Municipal Securities supported by such letters of credit
or guarantees, the Trust may be deemed to be concentrated in the banking
industry. (See "Certain Factors" below)
 
     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 delivery takes place. The 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 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.
 
     TAXABLE MONEY MARKET SECURITIES.  Under normal operating circumstances,
Fund assets will be managed with a view towards producing only income that is
exempt from federal income taxation. However, the 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
("FDIC"), bankers' acceptances, high-grade commercial paper guaranteed or issued
by domestic corporations and repurchase agreements secured by such obligations.
 
     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
 
                                        5
<PAGE>   75
 
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. Use
of repurchase agreements may cause the Fund to earn income which would be
taxable to its shareholders.
 
     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 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.
 
     CERTAIN FACTORS.  Naturally, there can be no assurance that the Fund will
achieve its investment objective or be able continuously to maintain a net asset
value per share of $1.00. The characteristics of short-term Municipal Securities
are such that the price stability and liquidity of the Fund may not be equal to
that of a money market fund which exclusively invests in short-term taxable
money market securities. While the Adviser believes that the purchase of
variable rate demand Municipal Securities will facilitate maintaining a $1.00
per share net asset value, the Fund is still expected to have a significantly
longer average maturity than a general purpose taxable money market fund with
the result that the pricing of its portfolio will tend to be more subject to
short-term interest rate fluctuations.
 
     In addition, the Fund expects that substantially all the demand rights of
the 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 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
 
     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, 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 the
     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
 
                                        6
<PAGE>   76
 
     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 the Fund contemplates investing in are variable rate demand Municipal
     Securities supported by letters of credit or guarantees issued by domestic
     branches of domestic banks).
 
          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, other than by entering into repurchase agreements and
     through the purchase of participation in privately negotiated loans and
     portions of publicly issued debt obligations that are in accordance with
     its investment objective and policies; provided, however, that the 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.
 
     The following additional investment restriction may be changed without the
vote of a majority of the outstanding Shares of the Fund.
 
     The 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 FUND?
 
GENERAL
 
     Shares of the Fund 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 Fund's 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 Fund 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 Fund 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 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, Shares may also be purchased by wiring funds
to the Fund's custodian as described below under "Purchase by Federal Funds
Wire."
 
                                        7
<PAGE>   77
 
     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. The 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 the Fund's portfolio securities that
the 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 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 new transaction in
your account, which will also show the total number of Shares owned by you and
the number of Shares being held in safekeeping by Cardinal Management Corp., as
the Fund's 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 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.
 
PURCHASE BY FEDERAL FUNDS WIRE
 
     Investments in Shares of the Fund 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 Fund (800) 282-9446, toll free,
prior to wire transfer of its 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: Cardinal Tax Exempt Money Market Fund
           [Include Fund Account Number and Name of Account Holder]
 
                                        8
<PAGE>   78
 
     Funds transmitted by wire will be invested in Shares of the 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.
 
PURCHASE BY MAIL
 
     Investment in Shares of the Fund may be made by mail by sending a check or
other negotiable bank draft payable to the order of "Cardinal Tax Exempt Money
Market Fund" together with, in the case of an initial purchase, an Application
Form to:
 
           Cardinal Tax Exempt Money Market 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 Fund
within one Business Day following receipt by The Ohio Company. Checks drawn on
non-member banks may take considerably longer. The Transfer Agent or the Group
will attempt to notify the investor upon receipt of the latter type of check as
to the possible delay and to arrange for a better means of transmittal of funds.
THE GROUP STRONGLY RECOMMENDS THAT INVESTORS OF SUBSTANTIAL AMOUNTS USE FEDERAL
FUNDS TO PURCHASE SHARES.
 
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 Shares of the 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?
 
     The Fund's net income is declared as a dividend and accrued on each
Business Day immediately prior to the determination of the 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 accrued discount earned and premium amortized), plus
realized net short-term capital gains (losses) due to portfolio transactions (if
any), less the accrued expenses of the Fund applicable to that dividend period.
The Fund does not expect to realize any long-term capital gains due to its
policy of investing in securities maturing in 13 months or less.
 
     All dividends of net income are credited to each shareholder's account
daily and automatically reinvested in additional Shares of the Fund at the net
asset value on the last Business Day of each month. Shareholders, however, may
elect to receive monthly the 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 writing. 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.
 
                                        9
<PAGE>   79
 
     Should the 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 the Fund's net asset
value per share were reduced, or expected to be reduced, below $1.00, the
Trustees might suspend further dividend accruals until the net asset value
returned to $1.00. Thus, extraordinary expenses or losses or depreciation may
result in no dividends being accrued for the period during which an investor
holds Shares as well as a redemption price lower than the purchase price for
such Shares.
 
                          HOW MAY I REDEEM MY SHARES?
 
     Investors may redeem Shares of the 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 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 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
 
                                       10
<PAGE>   80
 
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 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
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 Fund 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 Fund 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 Fund's 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 Fund 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 Fund's Systematic Withdrawal Plan.
Please contact The Ohio Company for the appropriate form.
 
                                       11
<PAGE>   81
 
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 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 not less than $250. 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 the 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 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 Fund
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 Fund offers 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 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 Shares of the Fund for shares of:
 
           Cardinal Aggressive Growth Fund,
           an equity fund seeking appreciation of
           capital (upon the payment of the applicable sales charge);
 
           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);
 
           The Cardinal Fund,
           an equity fund seeking long-term growth
           of capital and income (upon the payment of
           the applicable sales charge);
 
                                       12
<PAGE>   82
 
           Cardinal Government Obligations Fund,
           a fund investing in securities issued
           or guaranteed by the U.S. Government
           (upon the payment of the applicable
           sales charge); or
 
           Cardinal Government Securities Money Market Fund,
           a short-term U.S. Government securities fund
           (without payment of any sales charge).
 
     Notwithstanding the foregoing and subject to the limitations contained in
the following paragraph, exchanges of Fund Shares for 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 shares of that Cardinal Load Fund. If, however, the Shares of
Fund to be exchanged were acquired as a result of an exchange of shares of the
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
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 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.
 
     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.
 
                       HOW IS NET ASSET VALUE CALCULATED?
 
     The Fund's 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 the Fund, less its liabilities, by the
total number of Shares outstanding. Expenses and fees of the Fund, 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 the Fund to use its
best efforts, under normal circumstances, to maintain a constant net asset value
of $1.00 per share. The 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. The 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.
 
                                       13
<PAGE>   83
 
                     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 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. 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.
 
                              WHAT ABOUT MY TAXES?
 
FEDERAL TAXES
 
     The 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
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 Fund will also be treated as tax preference items in
computing the alternative minimum tax to the extent, if any, that distributions
by the Fund are attributable to interest earned by the 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 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 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.
 
                                       14
<PAGE>   84
 
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 Fund 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 Securities held by the Fund during the
preceding year.
 
     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, who are
elected by the shareholders of the Group's funds and who 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. The Ohio
Company receives no fees under its Distribution Agreement with the Group.
 
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 and for CTEMT.
 
     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 a voting stock, may be considered controlling persons of The Ohio
Company. The Ohio Company serves as principal underwriter for each of the
Cardinal Funds and for CTEMT.
 
     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 December 22, 1995, David C. Will has been primarily
responsible for the day-to-day management of the portfolio of CTEMT (the Fund's
predecessor). It is expected that, upon consummation of the Reorganization, Mr.
Will will be the portfolio manager for the Fund. Mr. Will has been a Vice
President of the Adviser and The Ohio Company since 1990 and has more than
 
                                       15

25 years of investment management experience. 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 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 distributions 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 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.
 
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 Fund will bear the following expenses relating to
its operations: organizational expenses, taxes, interest, any brokerage fees and

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, each having its own class of shares. The
other funds of the Group are The Cardinal Fund, Cardinal Government Obligations
Fund, Cardinal Government Securities Money
 
                                       16
<PAGE>   86
 
Market Fund, Cardinal Balanced Fund and Cardinal Aggressive Growth Fund. 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 Fund's
investment advisory agreement 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 and may be
removed by the Board of Trustees or shareholders in accordance with the
provisions of the Declaration of Trust and By-Laws of the Group and 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.

                      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") and Cardinal Tax
Exempt Money Market Fund ("CTEMMF") (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 Prospectus, CTEMMF may 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 CTEMMF will be those guaranteed by domestic
and foreign banks having, at the time of investment, assets in excess of
$500,000,000 (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 $500,000,000 (as of the date of its most recently published
financial statements).





                                      B-1
<PAGE>   93
         COMMERCIAL PAPER.  Commercial paper in which TCF, CGOF and CTEMMF may
invest 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.

         TCF, CGOF and CTEMMF 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 and
CTEMMF 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 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





                                      B-2
<PAGE>   94
         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, 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.





                                      B-3
<PAGE>   95
                 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 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





                                      B-4
<PAGE>   96
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 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.





                                      B-5
<PAGE>   97
         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 "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





                                      B-6
<PAGE>   98
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 and CTEMMF
may 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, the 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 nor CTEMMF's commitments to purchase "when-issued" or
"delayed-delivery" securities will exceed 25% of the value of its assets.

         When CGOF, CGSMMF or CTEMMF engages in "when-issued" or
"delayed-delivery" transactions, such Fund 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 and CTEMMF 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.

         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





                                      B-7
<PAGE>   99
TCF and CGOF 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.

         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 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





                                      B-8
<PAGE>   100
may involve currencies of foreign countries, TCF 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 TCF'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 will acquire such securities only when the Adviser believes the
risks associated with such investments are minimal.

         OPTIONS TRADING.  Each of TCF and CGOF 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 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





                                      B-9
<PAGE>   101
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.

         FUTURES CONTRACTS.  As discussed in the Prospectuses of the TCF and
CGOF, 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 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





                                      B-10
<PAGE>   102
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).

         Each of TCF and CGOF 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).





                                      B-11
<PAGE>   103
         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";

         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





                                      B-12
<PAGE>   104
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:

         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; or

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

         In addition, TCF has the following nonfundamental investment
restrictions: (1) TCF may not purchase or retain securities of any issuer if,
to the knowledge of the Group, the officers and trustees of the Group and the
officers and directors of its investment adviser, who each own beneficially
more than 1/2 of 1% of the outstanding securities of such issuer together own
beneficially more than 5% of such securities, (2) mortgage or hypothecate the





                                      B-13
<PAGE>   105
Fund's assets in excess of one-third of the Fund's total assets, (3) 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 (4) 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.

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 Securities
and Exchange Commission (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 rate may vary greatly from year to year as well as within a
particular year, and may also be affected by cash





                                      B-14
<PAGE>   106
requirements for redemptions of Shares.  For the fiscal period ending September
30, 1996, the Group estimates that the portfolio turnover rate for each of TCF
and CGOF will not exceed 50%.  Portfolio turnover will not be a limiting factor
in making investment decisions.

                            MANAGEMENT OF THE GROUP

         The trustees and officers of the Group, together with their addresses
and principal business occupations and other affiliations during the last five
years, are shown below.  Each person named as a trustee also serves as a
director of The Cardinal Fund Inc. and also serves as a trustee of Cardinal
Government Securities Trust, Cardinal Tax Exempt Money Trust and Cardinal
Government Obligations Fund.  Each trustee who is an "interested person" of the
Group, as that term is defined in the 1940 Act, is indicated by an asterisk.

___________________________________
       *During the fiscal year ended September 30, 1995, John L. Schlater, a
former officer of The Ohio Company and the Adviser, had served as a trustee of
the Group but no longer does so as of the date hereof.  Mr. Schlater did not
receive any compensation from the Group or the Fund Complex.

       **For purposes of this Table, Fund Complex means one or more mutual
funds, including the Group, which have a common investment adviser or
affiliated investment advisers or which hold themselves out to the public as
being related.

</TABLE>

                      PRINCIPAL SHAREHOLDERS OF THE GROUP

       There were no persons known to the Group to be the beneficial owner of
more than 5% of any Fund's Shares or of the total number of the Group's shares
outstanding as of October 26, 1995.

                                  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





                                      B-18
<PAGE>   110
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 and
(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.  In addition, the Adviser
also provides similar services to the other two funds of the Group, Cardinal
Balanced Fund ("CBF") and Cardinal Aggressive Growth Fund ("CAGF"), and
receives a fee from each such Fund, computed and accrued daily and paid
monthly, based on an annual rate of .75% of the daily net asset value of that
Fund.  For the fiscal years ended September 30, 1995 and 1994, and the fiscal
period ended September 30, 1993, fees earned under the Investment Advisory
Agreement, with respect to CBF, were $101,585, $103,264 and $11,128,
respectively, and, with respect to CAGF, were $71,508, $66,792 and $5,058,
respectively.

       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, John L. Schlater, Hannibal L.  Godwin III, 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





                                      B-19
<PAGE>   111
willful misfeasance, bad faith, or negligence on the part of the 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.

       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.

       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





                                      B-20
<PAGE>   112
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 Adviser, on behalf of the Funds, may direct brokerage transactions to
Columbine Research in return for the provision of research services.   Such
brokerage transactions are subject to the requirements as to price and
execution as described above.  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.

       In addition, 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
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.

       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).





                                      B-21
<PAGE>   113
       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 $21 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





                                      B-22
<PAGE>   114
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.

                                    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 most restrictive expense limitation
applicable to the Funds limit each Fund's aggregate annual expenses, including
management and advisory fees but excluding interest, taxes, brokerage
commissions, and certain other expenses, to 2 1/2% of the first $30 million of
a Fund's average net assets, 2% of the next $70 million of such Fund's average
net assets, and 1 1/2% of such Fund's remaining average net assets.  Any
expense reimbursements will be estimated daily and reconciled and paid on a
monthly basis.

                                THE DISTRIBUTOR

       The Ohio Company serves as agent for the Funds in the distribution of
their Shares pursuant to a Distribution Agreement dated June 18, 1993, as
amended as of January 10, 1996 (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 and retain all or a portion of the sales charges with respect to its
sales of Shares of TCF and CGOF.





                                      B-23
<PAGE>   115
       As described in the Prospectus, the Group has adopted a Distribution and
Shareholder Service Plan (the "Plan") pursuant to Rule 12b-1 under the 1940 Act
under which each of TCF and CGOF (collectively, the "12b-1 Funds") is
authorized to pay The Ohio Company for payments it 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 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 that 12b-1 Fund.

       As required by Rule 12b-1, the 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 indirect financial interest in the operation of the Plan
(the "Independent Trustees").  The 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 Shares of that 12b-1 Fund.  Any change in the Plan that would
materially increase the distribution cost to a 12b-1 Fund requires shareholder
approval.  The Trustees review quarterly a written report of such costs and the
purposes for which such costs have been incurred.  The Plan may be amended by
vote of the Trustees, including a majority of the Independent Trustees, cast in
person at a meeting called for that purpose.  For so long as the 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
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 Shares of
such 12b-1 Fund.

       The Plan will continue in effect for successive one-year periods,
provided that each such continuance is specifically approved (i) by the vote of
a majority of the Independent Trustees, and (ii) by 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 Plan should be implemented or continued.  In addition the Trustees
in approving the Plan must determine that there is a reasonable likelihood that
the Plan will benefit the 12b-1 Funds and their Shareholders.





                                      B-24
<PAGE>   116
       The Board of Trustees of the Group believes that the 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 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 Shares of a 12b-1
Fund purchased and held by The Ohio Company for the accounts of its customers
and 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 Shares of that 12b-1 Fund held
during the period in customer accounts for which The Ohio Company has provided
services under this Agreement.

       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.

                     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.

                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

       The Funds' Shares may be purchased at the public offering price and 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, and through other broker-dealers who
are members of





                                      B-25
<PAGE>   117
the National Association of Securities Dealers, Inc. and have sales agreements
with The Ohio Company.

       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 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 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





                                      B-26
<PAGE>   118
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 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





                                      B-27
<PAGE>   119
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.

       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





                                      B-28
<PAGE>   120
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 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





                                      B-29
<PAGE>   121
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 no tax liability with respect
to such gains, and the distributions will be taxable to shareholders as
long-term capital gains





                                      B-30
<PAGE>   122
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 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, four of which represent interests in the Funds.  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
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.

<PAGE>   124
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
Section 16(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 make any representation other than those contained
in the Prospectuses and this Statement of Additional Information.

                            PERFORMANCE INFORMATION

Yields
- - ------
       The yield of TCF and CGOF will be 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 TCF and CGOF 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 TCF's or CGOF'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 TCF's and CGOF's Shares and to the relative
risks associated with the investment objectives and policies of those Funds.

       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 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.

       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.

<PAGE>   126
Calculation of Total Return
- - ---------------------------

       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 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 CGOF's Prospectus, from time to time CGOF
may include in its sales literature and shareholder reports a quote of a
current "distribution" rate.  The current distribution rate is computed by
dividing the total amount of dividends per share paid by CGOF 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 and CGOF, 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. 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 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, U.S.A. Today and Consumer
Reports.  In addition to performance information, general information about the
Funds that appears in a publication such as those mentioned above may be

                                    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.

       The following summarizes the four 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.

       Moody's applies numerical modifiers (1, 2, and 3) with respect to bonds
rated Aa through Baa.  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 four 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.

       To provide more detailed indications of credit quality, the ratings from
AA to BBB may be modified by the addition of a plus or





                                      A-2

minus sign to show relative standing within this major rating category.

       The following summarizes the four 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 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.

       The following summarizes IBCA's four 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.

<PAGE>   131
       The following summarizes Thomson's description of its four 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.

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





                                      A-4
<PAGE>   132
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.

The Cardinal Fund Inc. (the "Fund") is a diversified, open-end, management
investment company. The primary investment objective of the Fund is to achieve
long-term growth of capital and income through selective participation in the
long-term progress of American businesses and industries. The policy of the Fund
is generally to invest in equity securities. Current income, while a factor in
portfolio selection, is secondary to the Fund's primary objective. There can be
no assurance that the Fund's objective will be achieved.

The Fund has entered into an Agreement and Plan of Reorganization and
Liquidation, dated as of December 1, 1995 (the "Plan"), with The Cardinal Group,
an Ohio business trust (the "Group"). Pursuant to the Plan, The Cardinal Fund, a
series of the Group (the "Acquiring Fund"), would acquire all of the assets of
the Fund in exchange for the assumption of all of the Fund's liabilities and a
number of full and fractional shares of the Acquiring Fund having an aggregate
net asset value equal to the Fund's net assets (the "Reorganization"). The Fund
would then be liquidated, and the shares of the Acquiring Fund would be
distributed to Fund shareholders.

The Reorganization is subject to certain regulatory approvals and to approval by
the shareholders of the Fund at a Special Shareholders Meeting currently
expected to be held in March, 1996. If the shareholders approve the
Reorganization, it is expected that the Reorganization would be effected on or
about March 31, 1996; however, the Reorganization may be effected on such
earlier or later date as the Group and the Fund may determine. There can be no
assurance that the Reorganization will take place when or as currently proposed.

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.

From time to time the Fund advertises "average annual total return" and
"cumulative return." SUCH TOTAL RETURN FIGURES AND CUMULATIVE RETURN 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 one-, five-and ten-year
periods and from September 30, 1975 (which periods will be stated in the
advertisement). 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 is
deducted from the initial investment at the time of investment. 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 is
deducted from the initial investment at the time of investment. If the sales
charge were not deducted, the average annual total return and cumulative return
advertised would be higher.
 
Investors may also judge the performance of the Fund by comparing its
performance to the performance of other mutual funds or mutual fund portfolios
with comparable investment objectives and policies through various mutual fund
or market indices 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 the Consumer Price Index and to other 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 and comparisons to such indices or
data may be included in advertisements and in reports to shareholders.

WHAT IS THE FUND?
- - --------------------------------------------------------------------------------
 
The Fund was organized on September 16, 1966, as an Ohio corporation and is
registered and operates as a diversified, open-end management investment company
as defined in the Investment Company Act of 1940 and commonly known as a mutual
fund.
 
- - --------------------------------------------------------------------------------
WHAT ARE THE INVESTMENT OBJECTIVE AND POLICIES OF THE FUND?
- - --------------------------------------------------------------------------------
 
The investment objective of the Fund is to achieve long-term growth of capital
and income through selective participation in the long-term progress of American
business and industries. The investment
 
6
<PAGE>   8
 
objective with respect to the Fund is a fundamental policy and as such may not
be changed without a vote of the holders of a majority of the outstanding Shares
of the Fund. The policy of the Fund is generally to invest in equity securities
of companies which, in the opinion of The Ohio Company, are growth oriented. The
securities purchased by the 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. Current income, while a
factor in portfolio selection, is secondary to the primary objective. This
policy of normally investing in equity securities believed to have a potential
for long-term capital appreciation means that the assets of the 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 Fund's equity position
should be reduced. At such times, and otherwise for cash management purposes,
the Fund may hold its assets in cash or invest its assets in investment grade
debt securities, U.S. Government securities, repurchase agreements and preferred
stock.
 
A repurchase agreement is an agreement under which an investor (such as the
Fund) purchases a security 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 Fund's investment adviser deems creditworthy under
guidelines approved by the Fund's Board of Directors. At the time of purchase,
the bank or securities dealer agrees to repurchase the underlying security 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. Securities subject to repurchase agreements
will be U.S. Government securities. Under the Investment Company Act of 1940, as
amended (the "1940 Act"), repurchase agreements are considered to be loans by
the Fund. The Fund will only enter into a repurchase agreement where (i) the
underlying securities are of the type which the Fund's investment guidelines
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 custodian or a bank acting as agent. The Ohio
Company will be responsible for continuously monitoring such requirements. 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 security 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.
 
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 Ohio Company, 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 Statement of Additional Information.
 
The Fund is not intended to provide a complete and balanced investment program
for an investor. There is no guarantee that the investment objective of the Fund
will be realized.

HOW DO I PURCHASE SHARES OF THE FUND?
- - --------------------------------------------------------------------------------
 
GENERAL
 
The Fund's Shares may be purchased at the public offering price through The Ohio
Company, principal underwriter of the Fund's 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.
 
                                                                              7
<PAGE>   9
 
Subsequent purchases of Shares of the Fund may be made by ACH processing as
described under "WHAT OTHER SHAREHOLDER PROGRAMS ARE PROVIDED? -- ACH
Processing" below.
 
The minimum initial investment for individuals is $1,000, except the initial
investment for an applicant investing by means of the Automatic Investment Plan
(see "WHAT OTHER SHAREHOLDER PROGRAMS ARE PROVIDED?") must be at least $50.
Subsequent investments must be in amounts of at least $50.
 
Due to the high cost of maintaining accounts, the Fund 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 to a
net asset value below $500. A shareholder will be notified in writing that the
value of the account is less than $500 and allowed 30 days to increase the
account 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. Shares of the Fund may be redeemed through a
securities dealer, investment adviser, agent or other fiduciary which may charge
a fee for its services in connection with the redemption. No redemption charge
is imposed by the Fund or by The Ohio Company, the Fund's principal distributor.
 
PUBLIC OFFERING PRICE
 
The public offering price of Shares of the Fund is the net asset value per share
next determined after receipt by The Ohio Company of an order and payment, plus
a sales charge as follows:

made at one time by an individual, or an individual, his or her 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 officers, directors, and
employees of the Fund, or by full-time employees of The Ohio Company, who have
been such for at least 90 days or by qualified retirement plans for such
persons.

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 Fund. 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 the Fund 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 Fund. 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

8
<PAGE>   10
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 Shares of the Fund on the
periodic basis you select. Confirmation of your purchase of Fund Shares will be
provided by the Fund. 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.

MAY MY TAX SHELTERED RETIREMENT PLAN INVEST IN THE FUND?
- - --------------------------------------------------------------------------------

Shares of the Fund qualify for purchase in connection with the following tax
sheltered retirement plans:
 
     -- Individual retirement account ("IRAs") plans
 
     -- Simplified Employee Pension Plans
 
     -- 403(b)(7) Custodial Plans sponsored by certain tax-exempt employers
 
     -- Pension, profit-sharing and 401(k) plans qualifying under Section 401(a)
        of the Internal Revenue Code

- - --------------------------------------------------------------------------------
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 Shares of the Fund and of any other fund of the Cardinal
family of funds which is sold with a sales charge (collectively, the "Cardinal
Load Funds") 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 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. 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
highest sales charge applicable to the shares actually purchased. If the full
amount indicated is not purchased, such escrowed shares will be involuntarily
redeemed to pay the additional sales charge, if necessary. Dividends on escrowed
shares, whether paid in cash or reinvested in additional shares of the
applicable Cardinal Load Fund, are not subject to escrow. The escrowed 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 shares of the Cardinal
Load Fund designated by you subject to the rate of sales charge applicable to
the actual amount of the aggregate
 
                                                                             9
<PAGE>   11
 
purchases. This program, however, may be modified or eliminated at any time or
from time to time by the Fund without notice.
 
CONCURRENT PURCHASES
 
For purposes of qualifying for a lower sales charge, you have the privilege of
combining "concurrent purchases" of Shares of the Fund and of one or more of the
other Cardinal Load Funds. For example, if you concurrently purchase Shares of
the Fund at the total public offering price of $50,000 and shares of another
Cardinal Load Fund at the total public offering price of $50,000, the sales
charge 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 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 Fund without notice thereof.
 
RIGHTS OF ACCUMULATION
 
After your initial purchase of Shares you may also be eligible to pay a reduced
sales charge for your subsequent purchases of Shares where the total public
offering price of Shares then being purchased plus the then aggregate current
net asset value of Shares of the Fund and of shares of any Cardinal Load Fund
held in your account equals $100,000 or more. You would be able to purchase
Shares at the public offering price applicable to the total of (a) the total
public offering price of the Shares of the Fund then being purchased plus (b)
the then current net asset value of Shares of the Fund and of shares of any
other Cardinal Load Fund held in your account. For purposes of determining the
aggregate current net asset value of shares held in your account, you may
include 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 Fund without notice thereof.
 
- - --------------------------------------------------------------------------------
ARE THERE ANY SPECIAL PURCHASE PROGRAMS FOR CERTAIN RETIREMENT PLANS?
- - --------------------------------------------------------------------------------
 
No sales charge is imposed on purchases of Shares of the Fund by trusts
qualifying under Section 401(a) of the Internal Revenue Code of 1986, as amended
(the "Code"), and by deferred compensation plans of state and local governments
and tax exempt organizations qualifying under section 457 or 403(b) of the Code
(collectively "Qualifying Plans"), so long as The Ohio Company serves as either
a trustee or an investment adviser for the applicable Qualifying Plans.

- - --------------------------------------------------------------------------------
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 Fund from time to time shall determine and from net income and net realized
capital gains of the Fund. It is the policy of the 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, dividends and distributions will be made only in additional
Shares of the Fund and not in cash.
 
Shareholders may elect to receive cash distributions by using ACH processing as
described under "WHAT OTHER SHAREHOLDER PROGRAMS ARE PROVIDED? - ACH Processing"
below.
 
10
<PAGE>   12
 
- - --------------------------------------------------------------------------------
HOW MAY I REDEEM MY SHARES?
- - --------------------------------------------------------------------------------
 
Investors may redeem Shares of the Fund at the net asset value per share next
determined following the receipt by the Fund's transfer agent, Cardinal
Management Corp., 215 East Capital Street, Columbus, Ohio 43215, of the
following: (a) written or telephonic notice to redeem, as described more fully
below, and (b) for Shares represented by certificates, either the share
certificates, properly endorsed, or properly executed stock powers. 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 and any share certificates or stock powers to
Cardinal Management Corp. without charge. Other broker-dealers may assist a
shareholder in redeeming his shares and may charge a fee for such services.
 
REDEMPTION BY MAIL
 
Shareholders may elect to redeem Shares of the Fund by submitting a written
request therefor to Cardinal Management Corp., the Fund's Transfer Agent at 215
East Capital Street, Columbus, Ohio 43215. Cardinal Management Corp. 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. Cardinal Management Corp. 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 elect to redeem Shares of the Fund by calling the Fund 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 or
another address.

Neither 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 Fund's telephone redemption procedures, acting upon instructions
reasonably believed to be genuine. The Fund will employ procedures designed to
provide reasonable assurances that instructions by telephone are genuine; if
these procedures are not followed, 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 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.
 
The Fund will make payment for redeemed Shares as promptly as practicable but in
no event more than seven days after receipt by Cardinal Management Corp. of the
foregoing notice and any share certificates and powers. The Fund 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.
 
                                                                            11
<PAGE>   13
 
The Fund 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?".
 
SYSTEMATIC WITHDRAWAL PLAN
 
If you are the owner of Shares of the Fund having a total value of $10,000 or
more at the current offering price, you may elect to redeem your 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 necessary form.
 
- - --------------------------------------------------------------------------------
HOW IS NET ASSET VALUE CALCULATED?
- - --------------------------------------------------------------------------------
 
The net asset value of the Fund is determined once daily as of 4:00 P.M.,
Columbus, Ohio time, on each business day the New York Stock Exchange is open
for business and on 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) where there is sufficient 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 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) minus all liabilities (including estimated accrued expenses) by the
total number of Shares then outstanding.
 
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 Quotations System ("NASDAQ") as of
the time of valuation on the day the securities are being valued. The Fund uses
one or more pricing services to provide such market prices. 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
Directors of the Fund.
 
Determination of the net asset value may be suspended at times when (a) trading
on the New York Stock Exchange is restricted or such Exchange is closed for
other than customary weekend and holiday closings, (b) an emergency as
determined by the Securities and Exchange Commission exists making disposal of
portfolio securities or valuation of net assets of the Fund not reasonably
practicable, or (c) the Securities and Exchange Commission has by order
permitted such suspension.
 
- - --------------------------------------------------------------------------------
DOES THE FUND PAY FEDERAL INCOME TAX?
- - --------------------------------------------------------------------------------
 
The Fund intends to qualify as a "regulated investment company" under the Code
for so long as such qualification is in the best interest of the 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.
 
12
<PAGE>   14
 
- - --------------------------------------------------------------------------------
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. 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 the
Fund bear to its gross income.
 
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.
 
Cardinal Management Corp. 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
Fund is exercised under the direction of the Fund's Board of Directors, which is
empowered to elect officers and contract with and provide for the compensation
of agents, consultants and other professionals to assist and advise in the
operation of the Fund.
 
INVESTMENT ADVISER
 
The Fund has entered into an Investment Advisory Agreement with The Ohio
Company, 155 East Broad Street, Columbus, Ohio 43215, an investment banking firm
organized in 1925. The Ohio Company is a member of the New York and Chicago
Stock Exchanges, other regional stock exchanges and the National Association of
Securities Dealers, Inc. Through its wholly-owned subsidiary, Cardinal
Management Corp., The Ohio Company also acts as investment adviser to Cardinal
Government Securities Trust, Cardinal Tax Exempt Money Trust, Cardinal
Government Obligations Fund, Cardinal Balanced Fund and Cardinal Aggressive
Growth Fund. Descendants of H.P. and R.F. Wolfe, deceased, and members of their
families, through their possession of a majority of a voting stock, may be
considered controlling persons of The Ohio Company.
 
In its capacity as investment adviser, and subject to the ultimate authority of
the Fund's Board of Directors, The Ohio Company is responsible for the overall
management of the Fund's business affairs. Since
 
                                                                             13
<PAGE>   15
December 22, 1995, John Bevilacqua has been primarily responsible for the
day-to-day management of the Fund's portfolio. 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.
 
For the Fund's fiscal year ended September 30, 1995, The Ohio Company received
compensation for its services provided under the Investment Advisory Agreement
of .5% of average net daily assets of the Fund during such year. The Ohio
Company may, however, periodically waive all or a portion of its advisory fee
with respect to the Fund to increase the net income 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.

TRANSFER AGENT
 
The Fund has entered into an Administration Agreement with Cardinal Management
Corp., 215 East Capital Street, Columbus, Ohio 43215, pursuant to which Cardinal
Management Corp. 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
Cardinal Management Corp. an annual fee, paid monthly, equal to $18 per
shareholder account plus out-of-pocket expenses.
 
DISTRIBUTOR

The Fund 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
continuously will be offered on a best efforts basis by The Ohio Company and
dealers selected by The Ohio Company. H. Keith Allen is an officer and director
of both the Fund and The Ohio Company. Frank W. Siegel is an officer and
director of the Fund and an officer of The Ohio Company. James M. Schrack II is
an officer of both the Fund and The Ohio Company.

CUSTODIAN
 
The Fund 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 OTHER SHAREHOLDER PROGRAMS ARE PROVIDED?
- - --------------------------------------------------------------------------------
 
ACH PROCESSING
 
The Fund now offers 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 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 Shares of the Fund for shares of:
 
     Cardinal Aggressive Growth Fund,
     an equity fund seeking appreciation
 
14
<PAGE>   16
 
     of capital (upon the payment of the
     applicable sales charge);
 
     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);
 
     Cardinal Government Obligations Fund,
     a fund investing in securities issued
     or guaranteed by the U.S. Government
     or its agencies or instrumentalities
     (upon the payment of the appropriate sales charge);
 
     Cardinal Government Securities Trust,
     a U.S. Government securities money market fund
     (without payment of any sales charge); or
 
     Cardinal Tax Exempt Money Trust,
     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 Qualifying Plans, for whom The Ohio
Company serves as either a trustee or an investment adviser, of Fund Shares for
shares of a Cardinal Load Fund may be completed without the payment of a sales
charge, and (ii) exchanges of Fund Shares by all other shareholders for 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 shares of such Cardinal Load Fund and the sales charge previously paid on the
Fund Shares to be exchanged.
 
The foregoing exchange privilege may be exercised only once in each calendar
quarter and 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. Cardinal Management Corp., as 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 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
the Fund by telephone. Neither 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.
 
For tax purposes, an exchange is treated as a redemption and a new purchase.
However, a shareholder may not include any sales charge on Shares of the Fund
for purposes of calculating the gain or loss realized upon an exchange of those
securities within 90 days of their purchase.
 
The Fund may at any time modify or terminate the foregoing exchange privilege.
The Fund, however, will give shareholders of the Fund 60 days' advance written
notice of any such modification or termination.
 
- - --------------------------------------------------------------------------------
WHAT ARE MY RIGHTS AS A SHAREHOLDER?
- - --------------------------------------------------------------------------------
 
The Fund has authorized 30,000,000 shares of Common Stock, without par value,
and all of a single class. Holders of Shares are entitled to one vote or
fraction thereof for each Share or fraction held. As provided by Ohio law, a
shareholder is entitled at any election of directors to cumulate his votes,
which means that a
 
                                                                             15
<PAGE>   17
 
shareholder may give one director a total number of votes equal to the number of
Shares owned times the number of directors to be elected, or distribute his
votes on the same principle among two or more directors. All Shares, when
issued, are fully paid and nonassessable and have no preemptive rights. Each
outstanding Share or fraction thereof is entitled to participate on a pro rata
basis in dividends, distributions and net assets upon liquidation. The Fund's
Shares carry redemption rights as described under the caption "HOW MAY I REDEEM
MY SHARES?".
 
Unless a shareholder expressly requests otherwise, dividends and capital gain
distributions will be reinvested in Shares of the Fund and not paid in cash.
 
- - --------------------------------------------------------------------------------
WHO PROVIDES SHAREHOLDER REPORTS?
- - --------------------------------------------------------------------------------
 
The Fund will provide shareholders monthly a summary statement describing any
purchases and sales of Shares of the Fund and dividend and capital gain
distributions.
 
Holders of Shares should direct all inquiries concerning such matters to
Cardinal Management Corp., 155 East Broad Street, Columbus, Ohio 43215.

                      STATEMENT OF ADDITIONAL INFORMATION


                             THE CARDINAL FUND INC.

         The Cardinal Fund Inc. (the "Fund") is an open-end management
investment company.  Much of the information contained in this Statement of
Additional Information expands upon subjects discussed in the Prospectus of the
Fund.  Capitalized terms not defined herein are defined in the Prospectus.  No
investment in Shares of the Fund should be made without first reading the
Prospectus of the Fund.


                       INVESTMENT OBJECTIVE AND POLICIES

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

         SECURITIES OF OTHER INVESTMENT COMPANIES.  The Fund may invest in
securities issued by other investment companies.  The 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 the
Fund.  As a shareholder of another investment company, the Fund would bear,
along with other shareholders, its pro rata portion of that company's expenses,
including advisory fees.  These expenses would be in addition to the advisory
and other expenses that the Fund bears directly in connection with its own
operations.  Investment companies in which the Fund may invest may also impose
a sales or distribution charge in connection with the purchase or redemption of
their shares and other types of commissions or charges.  Such charges will be
payable by the Fund and, therefore, will be borne directly by shareholders.

         REPURCHASE AGREEMENTS.  Securities held by the Fund may be subject to
repurchase agreements.  Under the terms of a repurchase agreement, the 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 Fund'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





                                      B-1
<PAGE>   25
(including accrued interest).  If the seller were to default on its repurchase
obligation or become insolvent, the Fund would suffer a loss to the extent that
the proceeds from a sale of the underlying portfolio securities were less than
the repurchase price under the agreement, or to the extent that the disposition
of such securities by the Fund were delayed pending court action.
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 Fund 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 Fund if presented with the question.  Securities subject to repurchase
agreements will be held by the Fund's custodian or another qualified custodian
or in the Federal Reserve/Treasury book-entry system.  Repurchase agreements
are considered to be loans by the Fund under the 1940 Act.

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

         The Fund deems the following to be matters of fundamental policy and
as such to be matters which the Fund will not change unless the changed policy
is otherwise lawful and is approved by holders of the majority of the
outstanding Shares of the Fund (defined as the vote, at an annual or special
meeting of shareholders of the Fund, of the lesser of (a) 67% or more of the
voting securities present at such meeting, if the holders of more than 50% of
the outstanding voting securities are present or represented by proxy, or (b)
more than 50% of the outstanding voting securities of the Fund):

         The Fund will not:

(1)      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;

(2)      make short sales of securities, except to the extent that the same
         shall be owned by the Fund (i.e., short sales "against the box") or
         purchase securities on margin;

(3)      write, purchase or sell puts, calls, or combinations thereof;

(4)      underwrite the securities of other issuers, except insofar as the Fund
         may technically be deemed an underwriter under the





                                      B-2
<PAGE>   26
         Securities Act of 1933 in connection with the disposition of portfolio
         securities;

(5)      purchase securities subject to restrictions on disposition under the
         Securities Act of 1933 if at the time of acquisition more than 5% of
         the total assets of the Fund would be invested in such securities;

(6)      concentrate more than 25% of the value of the total assets of the Fund
         (determined at the date of acquisition) in any particular industry;

(7)      purchase or sell real estate, except it is permissible to purchase
         securities secured by real estate or real estate interests or issued
         by companies that invest in real estate or real estate interests;

(8)      purchase or sell commodities, commodity contracts or futures
         contracts;

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

(10)     purchase the securities of any issuer if such purchase would cause
         more than 5% of the Fund's total assets upon such purchase to be
         invested in the securities of any one issuer (not including the
         government of the United States or corporations which are the
         instrumentalities of the United States);

(11)     mortgage, pledge or hypothecate any assets to a greater extent than
         15% of its gross assets taken at cost;

(12)     purchase the securities of any issuer if such purchase would cause the
         Fund to hold (i) more than 10% of the voting securities of such
         issuer, (ii) more than 10% of all debt securities of such issuer taken
         as a class, or (iii) more than 10% of all equity securities of such
         issuer preferred in any way over the common stock of such issuer taken
         as a class;

(13)     purchase securities of enterprises which have a record of less than
         three years' continuous operation, if such purchase would cause more
         than 5% of the total assets of the Fund to be invested in the
         securities of such enterprises;

(14)     purchase or retain any securities of an issuer if, to the knowledge of
         the Fund, the officers and directors of the Fund or the officers and
         directors of its investment adviser individually owning more than 1/2
         of 1% of the securities of





                                      B-3
<PAGE>   27
         such issuer together own beneficially more than 5% of the securities
         of such issuer;

(15)     purchase any securities from or sell any securities to (other than
         stock issued by the Fund) officers or directors of the Fund, any
         person or organization furnishing managerial or advisory services to
         the Fund, or related classes of persons as principals;

(16)     invest in companies for the purpose of exercising control or
         management thereof; or

(17)     change its classification as a "management company" under Section 4 of
         the Investment Company Act of 1940 or change its subclassifications as
         an "open-end company" or as a "diversified company" under Section 5 of
         the Investment Company Act of 1940.

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

         The Fund may not:

(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.

         If a percentage restriction or requirement set forth above is met at
the time of investment, a later failure to comply with the restriction or
requirement resulting from a change in the value of securities held by the Fund
will not be considered a violation of the policy.

         The Fund has represented to the California Department of Corporations
that, in order to comply with applicable regulations, it will acquire or retain
securities of other open-end management investment companies 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 Fund intends to comply with this
undertaking for so long as the Fund has its shares registered for sale in the
State of California or such representation is required by the California
Department of Corporations.

         In addition, the Fund has represented to the Texas State Securities
Board that the Fund will (1) limit its investment in warrants, valued at the
lower of cost or market, to 5% or less of the value of the Fund's net assets,
provided that included within that amount, but not to exceed 2% of the Fund's
net assets, may be warrants which are not listed on the New York or American
Stock Exchanges and that warrants acquired by the Fund in units or





                                      B-4
<PAGE>   28
attached to securities may be deemed to be without value, and (2) not invest in
oil, gas or other mineral leases.

         The Fund has also represented to the Ohio Division of Securities that
it will not invest its assets in the securities of other investment companies,
except by purchase in the open market where no commission or profit to a
sponsor or dealer results from the purchase other than the customary broker's
commission, or except when the purchase is part of a plan of merger,
consolidation, reorganization, or acquisition.  The Fund intends to comply with
this representation for so long as its Shares are registered for sale in the
State of Ohio.

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

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

         The portfolio turnover rate for the Fund for the two fiscal years
ended September 30, 1995 and 1994, were 19.78% and 23.20%, respectively.  The
portfolio turnover rate for the Fund 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.


                             MANAGEMENT OF THE FUND

         The directors and officers of the Fund, together with their addresses
and principal business occupations and other affiliations during the last five

trustee of Cardinal Government Securities Trust, Cardinal Tax Exempt Money

          *For the fiscal year ended September 30, 1995, John L. Schlater, a
former officer of The Ohio Company and Cardinal Management Corp., had served as
a director of the Fund but no longer does so as the date hereof.  Mr. Schlater
received no compensation from the Fund or the Fund Complex.

         **For purposes of this Table, Fund Complex means one or more mutual
funds, including the Fund, which have a common investment

adviser or affiliated investment advisers or which hold themselves out to the
public as being related.


                       PRINCIPAL SHAREHOLDERS OF THE FUND

         As of January 11, 1996, the only person known to the Fund to be the
beneficial owner of more than 5% of the Fund's outstanding Shares was The Ohio
Company, which, for its own account and as trustee for various pension plans
and trusts, owned beneficially 6.04% of the Fund's outstanding Shares.


                                  THE ADVISER

         The Fund has entered into an Investment Advisory Agreement with The
Ohio Company, an investment banking firm organized in 1925, pursuant to which
The Ohio Company furnishes the Fund with continuous investment advice,
research, statistical services and certain administrative support such as
providing and paying for all officers and employees of the Fund, office space
and supplies.  As compensation for such services, facilities and expenses The
Ohio Company receives a quarterly fee, accrued daily, based on an annual rate
of .5% of the daily net asset value of the Fund.  For the Fund's three fiscal
years ended September 30, 1995, 1994 and 1993, fees earned by The Ohio Company
under the Investment Advisory Agreement were $1,158,534, $1,325,607 and
$1,370,536, respectively.

         Under the Investment Advisory Agreement, if expenses (including the
adviser's fee but excluding interest and taxes) exceed 1-1/2% per annum of the
average daily net asset value for any fiscal year of the Fund, The Ohio Company
shall bear the excess.

         The Investment Advisory Agreement also provides that the advisory fee
payable pursuant to such Agreement shall be reduced by the amount of brokerage
commissions derived by The Ohio Company, as adviser, on orders executed by it
for the Fund on a stock exchange of which such Adviser is a member.

         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 both the Fund and The Ohio Company.  Frank W. Siegel is
an officer and director of the Fund and an officer of The Ohio Company.  James
M. Schrack II is an officer of both the Fund and The Ohio Company.

                             PORTFOLIO TRANSACTIONS

         Subject to the policies established by the Board of Directors of the
Fund, The Ohio Company, as Investment Adviser, is responsible for the Fund's
portfolio decisions and the placing of the Fund's portfolio transactions.  In
executing such transactions, The Ohio Company seeks to obtain the best net
results for the 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 Ohio Company generally
seeks reasonably competitive commission rates, for the reasons stated in the
prior sentence, the Fund will not necessarily be paying the lowest commission
or spread available.  For the Fund's three fiscal years ended September 30,
1995, 1994 and 1993, total brokerage fees paid by the Fund were $215,180,
$188,616 and $101,220, respectively, none of which was paid to The Ohio
Company.

         The Ohio Company may consider provision of research, statistical and
other information to the Fund or the Adviser in the selection of qualified
broker-dealers who effect portfolio transactions for the Fund so long as The
Ohio Company's ability to obtain the best net results for portfolio
transactions of the 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 Ohio Company in connection with its services to other clients.
Similarly, research services provided by brokers serving such other clients may
be useful to The Ohio Company in connection with its services to the Fund.
Although this information is useful to the Fund and The Ohio Company, except as
described below, it is not possible to place a dollar value on it.  It is the
opinion of the Board of Directors and The Ohio Company that the review and
study of this information will not reduce the overall cost to The Ohio Company
of performing its duties to the Fund under the Investment Advisory Agreement.
The Fund has authorized The Ohio Company to place brokerage transactions
through Pershing and Company, a division of Donaldson, Lufkin & Jenrette, in
return for Lipper Data information prepared for the Fund's Directors relating
to information on fees and expenses of other mutual funds.  In addition, during
the fiscal year ended September 30, 1994, The Ohio Company, on behalf of the
Fund, directed some brokerage transactions to Columbine Capital in return for
the provision of research services.  The amount of such transactions and
related commissions were $10,758,000 and $23,588, respectively.  The Ohio
Company has since not so directed any brokerage transactions to Columbine
Capital.  Such brokerage transactions with both Pershing and Company and
Columbine Capital are subject to the requirements as to price and execution as
described above.  The Fund is not authorized to pay brokerage


                                      B-10
<PAGE>   34
commissions which are in excess of those which another qualified broker would
charge solely by reason of brokerage and research services provided.

         Investment decisions for the Fund are made independently from those
for any other investment company or account managed by The Ohio Company.  Any
such other investment company or account may also invest in the same securities
as the Fund.  When a purchase or sale of the same security is made at
substantially the same time on behalf of the Fund and another investment
company or account, the transaction will be averaged as to price and available
investments will be allocated as to amount in a manner which The Ohio Company
believes to be equitable to the Fund and such other investment company or
account.  In some instances, this investment procedure may adversely affect the
price paid or received by the Fund or the size of the position obtained by the
Fund.  To the extent permitted by law, The Ohio Company may aggregate the
securities to be sold or purchased for the Fund with those to be sold or
purchased 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 Fund, The Ohio Company will not inquire or
take into consideration whether an issuer of securities proposed for purchase
or sale by the Fund is a customer of The Ohio Company or its subsidiaries or
affiliates and, in dealing with its customers, The Ohio Company or its
subsidiaries and affiliates will not inquire or take into consideration whether
securities of such customers are held by the Fund.

         The Fund did not during the fiscal year ended September 30, 1995, hold
any securities of its regular brokers or dealers, as defined in Rule 10b-1
under the 1940 Act, or their parent companies.


                  TRANSFER AGENT AND DIVIDEND DISBURSING AGENT

         The Fund has entered into an Administration Agreement with Cardinal
Management Corp., a wholly-owned subsidiary of The Ohio Company, pursuant to

dividend disbursing agent and administrator of plans for the Fund.  In

respectively, for services to the Fund pursuant to such Agreement.

                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

         The Fund's Shares may be purchased at the public offering price
through The Ohio Company, principal underwriter of the Fund's Shares, at its
address and number set forth on the cover page of this Statement of Additional
Information, and through other broker-dealers who are members of the National
Association of Securities Dealers, Inc. and have sales agreements with The Ohio
Company.

         Based upon the value of the Fund's portfolio securities and other
assets and the number of outstanding Shares as of the fiscal year ended
September 30, 1995, the net asset value and redemption price per share was
$13.23.  The total offering price per share was $13.85 per share (net asset
value divided by .9550, assuming the then current maximum sales charge of 4.5% 
of the offering price).  The total offering price is reduced on sales of 
$100,000 or more.

         The net asset value of the Fund is determined once daily as of 4:00
P.M., Columbus, Ohio time, (a) on each business day the New York Stock Exchange
is open for business and a purchase order has been received by the Fund, (b) on
each such business day when a redemption request is received, and (c) at such
other times as 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 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) minus all liabilities (including estimated accrued
expenses) by the total number of shares then outstanding.

         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 Quotations System ("NASDAQ") as of
the time of valuation on the day the securities are being valued.  The Fund
uses one or more pricing services to provide such market prices.  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 Directors of the Fund.

         The Fund may suspend the determination of the net asset value, 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 Securities and Exchange
Commission, (b) the Exchange is closed for other than customary weekend and
holiday closings, (c) an emergency exists as a result of which (i) disposal by
the Fund


                                      B-12
<PAGE>   36
of portfolio securities owned by it is not reasonably practicable or (ii) it is
not reasonably practicable for the Fund to determine the fair value of its net
assets, or (d) the Securities and Exchange Commission has by order permitted
such suspension.


                                     TAXES

         The Fund intends to qualify as a "regulated investment company" under
the Code for so long as such qualification is in the best interest of the
Fund's shareholders.  In order to qualify as a regulated investment company,
the 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 stock,
securities, or currencies; derive less than 30% of its gross income from the
sale or other disposition of stock, 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, the Fund must
distribute to its shareholders at least 90% of its investment company taxable
income for the year.  In general, the 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, the
Fund would be subject to a non-deductible excise tax equal to 4% of the
deficiency.

         Although the Fund expects to qualify as a "regulated investment
company" and to be relieved of all or substantially all federal income taxes,
depending upon the extent of its activities in states and localities in which
its offices are maintained, in which its agents or independent contractors are
located, or in which it is otherwise deemed to be conducting business, the Fund
may be subject to the tax laws of such states or localities.  In addition, if
for any taxable year the Fund does not qualify for the special tax treatment
afforded 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





                                      B-13
<PAGE>   37
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 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.

         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.

         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.  The Fund will
designate the portion of any distributions which





                                      B-14
<PAGE>   38
qualify for the 70% dividends received deduction.  The amount so designated may
not exceed the amount received by the Fund for its taxable year that qualifies
for the dividends received deduction.

         The 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 Prospectus 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 the Fund.  No attempt has been made to present a detailed
explanation of the federal income tax treatment of the Fund or its shareholders
and this discussion is not intended as a substitute for careful tax planning.
Accordingly, potential purchasers of Shares of the Fund are urged to consult
their tax advisers with specific reference to their own tax situation.  In
addition, the tax discussion in the Prospectus and this Statement of Additional
Information is based on tax laws and regulations which are in effect on the
date of the Prospectus and this Statement of Additional Information; such laws
and regulations may be changed by legislative or administrative action.


                            PERFORMANCE INFORMATION

         For the one-, five- and ten-year periods ended September 30, 1995, and
the period from September 30, 1975 to September 30, 1995, the average annual
total returns for the Fund were 9.63%, 13.25%, 12.15%, and 14.91%,
respectively.  For the one-, five- and ten-year periods ended September 30,
1995, and the period from September 30, 1975 to September 30, 1995, the
cumulative return figures for the Fund were 9.63%, 86.28%, 215.05% and
1,511.18%, respectively.  Each quotation of average annual total return was
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
the Fund equal to the ending redeemable value, according to the following
formula:
                                        n
                                P(T + 1)  = 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 total return is being calculated assuming a
complete redemption.  The calculation of average annual total return assumes
the deduction of the current maximum applicable sales charge (4.5%)


                                      B-15
<PAGE>   39
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 the Fund's
average account size.  Cumulative return is computed by using average annual
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.

         Investors may also judge the performance of the Fund by comparing its
performance to the performance of other mutual funds or mutual fund portfolios
with comparable investment objectives and policies through various mutual fund
or market indices such as those prepared by Dow Jones & Co., Inc. and, Standard
& Poor's Corporation and to data prepared by Lipper Analytical Services, Inc.,

NOTES TO FINANCIAL STATEMENTS

SEPTEMBER 30, 1995
 
(1) -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
The Cardinal Fund Inc. (the "Fund") is registered under the Investment Company
Act of 1940, as a diversified, open-end management investment company. The
following is a summary of significant accounting policies followed by the Fund
in the preparation of its financial statements. The policies are in conformity
with generally accepted accounting principles for investment companies.
 
Security Valuation--Investments listed or traded on a national securities
exchange are valued at the last sale price or, if there has been no recent sale,
at the last bid price. Investments traded in the over-the-counter market are
valued at the last sale price. If no quotations are available, portfolio
securities are valued in good faith by the Board of Directors to reflect their
fair value.
 
Security Transactions and Investment Income--Security transactions are accounted
for on the trade date and dividend income is recorded on the ex-dividend date.
Interest income is recorded on the accrual basis. In determining the net
realized gain or loss on securities sold, the cost of the securities has been
determined on the first-in, first-out (FIFO) cost basis. It is the Fund's policy
for its Custodian, or a third-party bank, to take possession of all securities
pledged as collateral for repurchase agreements and monitor the market value of
the collateral to ensure that it remains sufficient to cover the repurchase
agreements.
 
Distributions to Shareholders--Distributions and dividends are recorded by the
Fund on the record date. Income dividends are declared quarterly and any capital
gain distribution is declared annually.
 
Federal Income Taxes--No provision has been made for Federal taxes on the Fund's
income, since it is the policy of the Fund to comply with the provisions of the
Internal Revenue Code applicable to regulated investment companies and to make
sufficient distributions of taxable income and capital gains within the required
time to relieve it from all, or substantially all, Federal income taxes.
 
(2) -- PURCHASES AND SALES OF SECURITIES
 
The cost of purchases and proceeds from sales of investment securities
(excluding short-term obligations) during the year ended September 30, 1995
aggregated $43,227,000 and $91,217,776, respectively.
 
During the year ended September 30, 1995 the Fund realized on a FIFO cost basis
a net capital gain of $17,719,277 and $17,777,501 for book and tax purposes,
respectively.
 
At September 30, 1995, the book cost of investment securities was $164,059,806
and the tax cost was $164,085,672. The difference between book and tax cost is
attributable to securities acquired in the 1975 acquisition of the Ohio Capital
Fund, Inc. and remaining in the Fund's portfolio with a book cost of $68,235 and
a tax cost of $38,594.
 
As of September 30, 1995, for tax purposes, gross unrealized gains and gross
unrealized losses on investment securities were $60,316,804 and $1,439,149
respectively; resulting in a net unrealized gain of $58,877,655.
 
(3) -- TRANSACTIONS WITH AFFILIATES
 
As investment manager for the Fund, The Ohio Company (the Adviser), with whom
certain officers and directors of the Fund are affiliated is allowed an annual
fee of 0.5% of the average daily net assets of the Fund. For the year ended the
Fund paid or accrued $1,158,534 for investment management services. The Adviser
has agreed that if the aggregate expenses of the Fund, as defined, for any
fiscal year exceed the
 
                                                                     (continued)

expense limitation of any state having jurisdiction over the Fund, the Adviser
will refund to the Fund, or otherwise bear, such excess. This limitation did not
affect the calculation of the management fee during the year ended September 30,
1995. In addition to providing management and advisory services, The Ohio
Company pays the compensation of all officers and employees of the Fund and
provides office space and certain related facilities required by the Fund.
 
The Ohio Company, acting as the General Distributor and Dealer, reported to the
Fund that it received commissions after discounts to dealers from the sale of
shares of the Fund of $170,827 for the year ended September 30, 1995. Cardinal
Management Corp., a wholly-owned subsidiary of The Ohio Company, provides
transfer agent services to the Fund. Transfer agent service fees are based on a
monthly charge per shareholder account plus out-of-pocket expenses. For the year
ended September 30, 1995 the Fund paid or accrued $255,882 for transfer agent
services provided by Cardinal Management Corp.
 
(4) -- COMMITMENTS AND CONTINGENCIES
 
The Fund has an available $5,000,000 line of credit with its custodian, Fifth
Third Bank, which was unused at September 30, 1995. When used, borrowings under
this arrangement are secured by portfolio securities and can be used only for
short term needs of the Fund. No compensating balances are required and the
arrangement bears an interest rate of 106% of the custodian's prime lending
rate.
 
Fidelity Bond and Errors and Omissions insurance coverage for the Fund and its
officers and directors has been obtained through ICI Mutual Insurance Company
(ICI Mutual), an industry-sponsored mutual insurance company. Included in other
assets of the Fund is a deposit of $28,588, for the initial capital of ICI
Mutual. The Fund is also committed to provide $85,764 should ICI Mutual
experience the need for additional capital contributions.
 
Included in other assets is a $56,000 certificate of deposit which
collateralizes a standby letter of credit in connection with the Fund's
participation in ICI Mutual. This amount is not available for investment.

On November 13, 1995 the Board of Directors approved an Agreement and Plan of
Reorganization and Liquidation between the Fund and The Cardinal Group ("TCG").

Trustees have determined that this action is in the best interests of the
shareholders of the Fund and TCG. Shareholder approval will be sought and is
needed to ratify the transaction.

INDEPENDENT AUDITORS' REPORT
- - --------------------------------------------------------------------------------
 
The Shareholders and Board of Directors
The Cardinal Fund Inc.:
 
We have audited the accompanying statement of assets and liabilities of The
Cardinal Fund Inc. (the Fund), including the statement of investments, as of
September 30, 1995, and the related statement of operations for the year then
ended, the statements of changes in net assets for each of the years in the
two-year period then ended and the financial highlights for each of the years in
the five-year period then ended. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included verification of securities owned as of
September 30, 1995, by confirmation with the custodian and other appropriate
audit procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of The
Cardinal Fund Inc. as of September 30, 1995, the results of its operations for
the year then ended, the changes in its net assets for each of the years in the
two-year period then ended, and the financial highlights for each of the years
in the five-year period then ended, in conformity with generally accepted
accounting principles.

                      CARDINAL GOVERNMENT OBLIGATIONS FUND
 
Cardinal Government Obligations Fund (the "Fund") is a diversified, open-end,
management investment company. The investment objective of the Fund is 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 objective will be
achieved.
 
The Fund has entered into an Agreement and Plan of Reorganization and
Liquidation, dated as of December 1, 1995 (the "Plan"), with The Cardinal Group,
an Ohio business trust (the "Group"). Pursuant to the Plan, Cardinal Government
Obligations Fund, a series of the Group (the "Acquiring Fund"), would acquire
all of the assets of the Fund in exchange for the assumption of all of the
Fund's liabilities and a number of full and fractional shares of the Acquiring
Fund having an aggregate net asset value equal to the Fund's net assets (the
"Reorganization"). The Fund would then be liquidated, and the shares of the
Acquiring Fund would be distributed to Fund shareholders.
 
The Reorganization is subject to certain regulatory approvals and to approval by
the shareholders of the Fund at the Annual Shareholders Meeting currently
expected to be held in March, 1996. If the shareholders approve the
Reorganization, it is expected that the Reorganization would be effected on or
about March 31, 1996; however, the Reorganization may be effected on such
earlier or later date as the Group and the Fund may determine. There can be no
assurance that the Reorganization will take place when or as currently proposed.
 
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.

From time to time the Fund advertises "yield," "average annual total return" and
"cumulative return." SUCH YIELD FIGURES AND TOTAL RETURN FIGURES ARE BASED UPON
HISTORICAL EARNINGS AND ARE NOT INTENDED TO INDICATE FUTURE PERFORMANCE. The
"yield" of the Fund refers to the income generated by an investment in the Fund
over a 30-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 over a one-month period assuming reinvestment at a constant rate of
all income so generated is assumed to be generated for 12 consecutive one-month
periods. The "yield" of the Fund assumes the deduction of the maximum applicable
sales charge from the investment. If the sales charge were not deducted, the
yield of the Fund would be higher.
 
The average annual total return figures advertised by the Fund refer to the
return generated by an investment in the Fund over one- and five-year periods
and the period during which the Fund has been in operation (which periods will
be stated on the advertisement). The 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 reinvested. The return also assumes that the maximum applicable
sales charge is deducted from the initial investment at the time of investment.
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 is deducted from the initial investment at the time of
investment. If the sales charge were not deducted, the average annual total
return 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 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 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 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,
Consumer Reports, and U.S.A. Today. 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.

WHAT IS THE FUND?
- - --------------------------------------------------------------------------------
 
The Fund was organized on November 15, 1985, as a business trust under the laws
of the State of Ohio and is registered and operates as a diversified, open-end,
management investment company as defined in the Investment Company Act of 1940
and as commonly known as a mutual fund. The Trustees of the Fund have divided
its beneficial ownership into an unlimited number of transferable units called
Shares, which will be offered and sold to the public through The Ohio Company,
principal underwriter of the Fund's Shares. The proceeds from such sale, net of
the applicable sales charge, will be invested by the Fund as set forth below.
 
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 OBJECTIVE AND POLICIES OF THE FUND?
- - --------------------------------------------------------------------------------
 
The Fund's investment objective is 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 objective is a fundamental policy of the Fund, which means
that it may be changed only with the approval of a majority of the Fund's
Shares. A majority of the Fund's Shares means the favorable vote, at an annual
or special meeting, of shareholders holding the lesser of (a) 67% or more of the
Shares at such meeting, if holders of more than 50% of the outstanding Shares
are represented in person or by proxy, and (b) more than 50% of the outstanding
Shares. There can be no assurance that the investment objective can be met.
 
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.
 
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.
 
                                        7
<PAGE>   60
 
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 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 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 in the discretion of the Fund's 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.
 
                                        8
<PAGE>   61
 
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. 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.
 
The Fund may enter into repurchase agreements, which are transactions through
which an investor (such as the Fund) purchases a security (known as the
"underlying security") 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 Fund's Adviser deems creditworthy under guidelines approved by the
Fund's Board of Trustees. At the time of purchase, the bank or securities dealer
agrees to repurchase the underlying securities at the same price, plus specified
interest. Repurchase agreements are generally for a short period of time, often
less than a week. The Fund will not enter into a repurchase agreement with a
maturity of more than seven days if, as a result, more than 10% of the value of
its total assets would then be invested in such repurchase agreements. The Fund
will only enter into a repurchase agreement where (i) the underlying securities
are of the type which the Fund's investment guidelines 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 custodian or a bank acting as agent. The Fund's Adviser will be responsible
for monitoring such requirements. 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 security 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. Under the Investment Company Act of 1940, as amended (the "1940 Act"),
repurchase agreements are considered to be loans by the Fund.
 
The Fund may from time to time write covered call options on securities in its
portfolio. The Fund will realize a premium when it writes an option. The Fund
will write only covered call options, which means that in each instance the Fund
will continue to own the underlying security for as long as it remains obligated
as the writer of the option. The purchaser of the call option has the right to
purchase the underlying security at the agreed upon price, even though that
price may be less than the value of the security at the time the option is
exercised. The Fund would then suffer a loss equal to the excess, if any, of the
security's appreciation in value over the premium received for writing the
option. To facilitate closing purchase transactions (described below), the Fund
will ordinarily write only call options for which a secondary market exists on a
national securities exchange or in the over-the-counter market.
 
In order to realize a profit, to prevent an underlying security from being
called or to unfreeze an underlying security (thereby permitting its sale or the
writing of a new option on the security prior to the option's expiration), the
Fund may engage in a closing purchase transaction. The Fund will incur a loss if
the cost of the closing purchase transaction, plus transaction costs, exceeds
the premium received upon writing the original option. To effect a closing
purchase transaction, the Fund would purchase, prior to the exercise of an
option that it has written, an option of the same series as that on which it
desires to terminate its obligation. There can be no assurance that the Fund
will be able to effect a closing purchase transaction at a
 
                                        9
<PAGE>   62
 
time when it wishes to do so. When the Fund cannot effect a closing purchase
transaction, it will not be able to sell the underlying security unless the
option expires without exercise. Upon expiration of the option, the Fund would
continue to bear market risk in that security. The obligation of the Fund to
deliver securities upon the exercise of a covered call option which it has
written terminates upon the effectuation of a closing purchase transaction.
 
The Fund may use covered call option strategies as a means of increasing the
total return on the portfolio and also as a means of providing limited
protection against decreases in market value. The Fund will engage in this
activity, if at all, only to the extent permitted by the most stringent
applicable state regulations governing the writing of covered call options in
states where the Fund is selling its Shares. The aggregate value of securities
underlying outstanding options will not exceed 25% of the net assets of the
Fund.
 
The Fund may purchase put and call options on interest rate futures contracts
which are traded on a United States exchange or board of trade as a hedge
against changes in interest rates, and may enter into closing transactions with
respect to such options to terminate existing positions. An interest rate
futures contract provides for the future sale by one party and purchase by the
other party of a certain amount of a specific financial instrument (debt
security) at a specified price, date, time and place. An option on an interest
rate futures contract, as contrasted with the direct investment in such a
contract, gives the purchaser the right, in return for the premium paid, to
assume a position in an interest rate futures contract at a specified exercise
price at any time prior to the expiration date of the option. The Fund may
purchase put options on interest rate futures contracts to hedge its portfolio
securities against the risk of rising interest rates, and may purchase call
options on interest rate futures contracts to hedge against a decline in
interest rates. The Fund will write put or call options on interest rate futures
contracts only as part of closing purchase transactions to terminate its option
positions, and there is no guarantee that such closing transactions can be
effected. There can be no assurance that there will be a correlation between
price movements in the options on interest rate futures, on the one hand, and
price movements in the Fund's portfolio securities which are the subject of the
hedge, on the other hand. In addition, the Fund's purchase of put or call
options will be based upon predictions as to anticipated interest rate trends,
which could prove to be inaccurate. The Fund will purchase put or call options
on interest rate futures contracts only as a hedge against changes in the value
of securities in the Fund's portfolio that may result from market conditions,
and not for speculative purposes. The potential loss related to the purchase of
an option on interest rate futures contracts is limited to the premium paid for
the option. Options 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 5% of its total assets at any
one time in premiums paid for call options and put options.
 
Although, except as set forth above, the Fund does not intend to engage in
short-term trading of portfolio securities as a means of achieving its
investment objective, it may sell portfolio securities without regard to the
length of time they have been held whenever such sale will, in the Adviser's
opinion, strengthen the Fund's position and contribute to its investment
objective. Brokerage commissions are not normally charged on the purchase or
sale of securities issued or guaranteed by the U.S. Government, but such
transactions may involve costs in the form of spreads between bid and asked
prices.
 
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 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 Statement of
Additional Information.
 
In addition to the Fund's investment objective, the Fund has established a
number of other fundamental policies, changeable only with the approval of a
majority of the Fund's Shares, all of which are described in the Fund's
Statement Of Additional Information, including policies prohibiting (i) the
investment of more
 
                                       10
<PAGE>   63
 
than 10% of the value of the Fund's total assets in repurchase agreements
maturing in more than seven days, (ii) borrowing money, except from banks as a
temporary measure for extraordinary or emergency purposes, and then only in
amounts not exceeding 5% of the value of the Fund's total assets, (iii)
mortgaging, pledging or otherwise encumbering any portfolio security except as
may be necessary in connection with permissible borrowings, in which case the
mortgaging, pledging or encumbering cannot exceed 5% of the Funds's assets, (iv)
investing in covered call options where the aggregate value of the securities
underlying the options exceeds 25% of the net assets of the Fund, and (v)
investing more than 5% of the Fund's assets in premiums paid on put and call
options. Except for the investment objective and the matters described as
fundamental policies in the Statement Of Additional Information, all other
practices of the Fund are not fundamental policies.

HOW DO I PURCHASE SHARES OF THE FUND?
- - --------------------------------------------------------------------------------
 
GENERAL
 
The Fund's Shares may be purchased at the public offering price, described
below, through The Ohio Company, principal distributor of the Fund's 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. A
purchase will become effective upon receipt by The Ohio Company of an order and
payment of the public offering price.
 
Subsequent purchases of Shares of the Fund may be made by ACH processing as
described under "WHAT OTHER SHAREHOLDER PROGRAMS ARE PROVIDED? -- ACH
Processing" below.
 
Certificates reflecting ownership of the Fund's Shares will not be issued unless
specifically requested by the purchaser. In order to facilitate redemptions, it
is expected that most shareholders will not elect to receive certificates.
 
The minimum initial investment is $1,000. Subsequent investments must be in
amounts of at least $50.
 
Due to the high cost of maintaining accounts, the Fund 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 to a
net asset value below $500. A shareholder will be notified in writing that the
value of the account is less than $500 and allowed 30 days to increase the
account 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. Shares of the Fund may be redeemed through a
securities dealer, investment adviser, agent or other fiduciary which may charge
a fee for its services in connection with the redemption. No redemption charge
is imposed by the Fund or by The Ohio Company, the Fund's principal distributor.
 
PUBLIC OFFERING PRICE
 
The public offering price of Shares of the Fund is the net asset value per share
next determined after receipt by The Ohio Company of an order and payment, plus
a sales charge as follows:

</TABLE>
 
(See "HOW IS NET ASSET VALUE CALCULATED?" for a description of the computation
of net asset value per share.)
 
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 officers, trustees, and
employees of the Fund or by full-time employees of the Adviser or The Ohio
Company, who have been such for at least 90 days or by qualified retirement
plans for such persons.
 
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 Fund. 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 the Fund 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 Fund. 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 Shares of the Fund on the
periodic basis you select. Confirmation of your purchase of Fund Shares will be
provided by the Fund. 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.

        of the Internal Revenue Code
 
- - --------------------------------------------------------------------------------
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 Shares of the Fund and of any other fund of the Cardinal
family of funds which is sold with a sales charge (collectively, the "Cardinal
Load Funds"), 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 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. 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
highest sales charge applicable to the shares actually purchased. If the full
amount indicated is not purchased, such escrowed shares will be involuntarily
redeemed to pay the additional sales charge, if necessary. Dividends on escrowed
shares, whether paid in cash or reinvested in additional shares of the
applicable Cardinal Load Fund, are not subject to escrow. The escrowed 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 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 Fund without
notice.
 
CONCURRENT PURCHASES
 
For purposes of qualifying for a lower sales charge, you have the privilege of
combining "concurrent purchases" of Shares of the Fund and of one or more of the
other Cardinal Load Funds. For example, if you concurrently purchase Shares of
the Fund at the total public offering price of $50,000 and shares of another
Cardinal Load Fund at the total public offering price of $50,000, the sales
charge 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 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 Fund without notice thereof.
 
RIGHTS OF ACCUMULATION
 
After your initial purchase of Shares, you may also be eligible to pay a reduced
sales charge for your subsequent purchases of Shares where the total public
offering price of Shares then being purchased plus the then aggregate current
net asset value of Shares of the Fund and of shares of any Cardinal Load Fund
held in your account equals $100,000 or more. You would be able to purchase
Shares at the public offering
 
                                       13
<PAGE>   66
 
price applicable to the total of (a) the total public offering price of the
Shares of the Fund then being purchased plus (b) the then current net asset
value of Shares of the Fund and of shares of any other Cardinal Load Fund held
in your account. For purposes of determining the aggregate current net asset
value of shares held in your account, you may include 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 Fund without notice.
 
- - --------------------------------------------------------------------------------
ARE THERE ANY SPECIAL PURCHASE PROGRAMS FOR CERTAIN RETIREMENT PLANS?
- - --------------------------------------------------------------------------------
 
No sales charge is imposed on purchases of Shares of the Fund by trusts
qualifying under Section 401(a) of the Internal Revenue Code of 1986, as amended
(the "Code"), and by deferred compensation plans of state and local governments
and tax-exempt organizations qualifying under Section 403(b) or Section 457 of
the Code (collectively, "Qualifying Plans"), so long as The Ohio Company serves
as either a trustee or investment adviser for the applicable Qualifying Plans.
 
- - --------------------------------------------------------------------------------
WHAT DISTRIBUTIONS WILL I RECEIVE?
- - --------------------------------------------------------------------------------
 
The net income of the Fund is declared daily as a dividend 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 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 expected to be
distributed on a monthly basis.
 
Shareholders may elect to receive cash distributions by using ACH processing as
described under "WHAT OTHER SHAREHOLDER PROGRAMS ARE PROVIDED? -- ACH
Processing" below.
- - --------------------------------------------------------------------------------
HOW MAY I REDEEM MY SHARES?
- - --------------------------------------------------------------------------------
 
Investors may redeem Shares of the Fund at the net asset value per share next
determined following the receipt by the Fund's transfer agent, Cardinal
Management Corp., 215 East Capital Street, Columbus, Ohio 43215, of the
following: (a) written or telephonic notice to redeem, as described more fully
below, and (b) for Shares represented by certificates, either the share
certificates, properly endorsed, or properly executed stock powers. 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 and any share certificates or stock powers to
Cardinal Management Corp. without charge. Other broker-dealers may assist a
shareholder in redeeming his shares and may charge a fee for such services.
 
REDEMPTION BY MAIL
 
Shareholders may elect to redeem Shares of the Fund by submitting a written
request therefor to Cardinal Management Corp., the Fund's Transfer Agent at 215
East Capital Street, Columbus, Ohio 43215. Cardinal Management Corp. 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
 
                                       14
<PAGE>   67
 
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.
Cardinal Management Corp. 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 elect to redeem Shares of the Fund by calling the Fund 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 or
another address.
 
Neither 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 Fund's telephone redemption procedures, acting upon instructions
reasonably believed to be genuine. The Fund will employ procedures designed to
provide reasonable assurances that instructions by telephone are genuine; if
these procedures are not followed, 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 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.
 
The Fund will make payment for redeemed Shares as promptly as practicable but in
no event more than seven days after receipt by Cardinal Management Corp. of the
foregoing notice and any share certificates and powers. The Fund 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 Fund 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?".
 
SYSTEMATIC WITHDRAWAL PLAN
 
If you are the owner of Shares of the Fund having a total value of $25,000 or
more at the current offering price, you may elect to redeem your 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.
 
- - --------------------------------------------------------------------------------
HOW IS NET ASSET VALUE CALCULATED?
- - --------------------------------------------------------------------------------
 
The net asset value of the Fund is determined once daily as of 4:00 P.M.,
Columbus, Ohio time, on each business day the New York Stock Exchange is open
for business and on 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) where there is sufficient trading in the Fund's portfolio
securities that the Fund's net asset value per share might be materially
affected by changes in the value of its portfolio securities. The net asset
value per share of the Fund is computed by dividing the sum of the value of the
Fund's portfolio securities plus
 
                                       15
<PAGE>   68
 
any cash and other assets (including interest accrued but not received) minus
all liabilities (including estimated accrued expenses) by the total number of
Shares then outstanding.
 
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 Fund.
 
Determination of the net asset value may be suspended at times when (a) trading
on the New York Stock Exchange is restricted or such Exchange is closed for
other than customary weekend and holiday closings, (b) an emergency as
determined by the Securities and Exchange Commission exists making disposal of
portfolio securities or valuation of net assets of the Fund not reasonably
practicable, or (c) the Securities and Exchange Commission has by order
permitted such suspension.
 
- - --------------------------------------------------------------------------------
DOES THE FUND PAY FEDERAL INCOME TAX?
- - --------------------------------------------------------------------------------
 
The Fund intends to qualify as a "regulated investment company" under the Code
for so long as such qualification is in the best interest of the 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.
 
- - --------------------------------------------------------------------------------
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. 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 the
Fund bear to its gross income.
 
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
 
                                       16
<PAGE>   69
 
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.
 
Cardinal Management Corp. will inform shareholders at least annually of the
amount and nature of such income and capital gains.
 
- - --------------------------------------------------------------------------------
WHO MANAGES MY INVESTMENT IN THE FUND?
- - --------------------------------------------------------------------------------
 
Pursuant to the laws of Ohio and the Fund's Declaration of Trust, the
responsibility for the management of the Fund is vested in its Board of Trustees
which, among other things, is empowered by the Fund's Declaration Of Trust to
elect officers of the Fund and contract with and provide for the compensation of
agents, consultants and other professionals to assist and advise in such
management.
 
INVESTMENT ADVISER AND MANAGER
 
The Fund has entered into an Investment Advisory and Management Agreement
("Investment Advisory Agreement") with Cardinal Management Corp., an Ohio
corporation (the "Adviser"), 155 East Broad Street, Columbus, Ohio 43215, in
which the Adviser has agreed to serve as the Fund's investment adviser and
manager. In such capacity, and subject to the ultimate authority of the Fund's
Board of Trustees, the Adviser has agreed regularly to provide the Fund with
investment advice, including management of the Fund's portfolio securities, and
overall management of the Fund's affairs. Since the Fund's inception, John R.
Carle has been primarily responsible for the day-to-day management of the Fund's
portfolio. Mr. Carle has been a portfolio manager with the Adviser and/or The
Ohio Company since 1971.
 
The Adviser was organized in March, 1980, and currently provides investment
advisory services to Cardinal Government Securities Trust, Cardinal Tax Exempt
Money Trust, Cardinal Balanced Fund and Cardinal Aggressive Growth Fund. The
Adviser is a wholly-owned subsidiary of The Ohio Company, an Ohio corporation.
The Ohio Company is an investment banking firm organized in 1925 and serves as
the principal underwriter for each of the foregoing funds and as the investment
adviser and principal underwriter for The Cardinal Fund Inc. The Ohio Company is
a member of the New York and Chicago Stock Exchanges, other regional stock
exchanges and the National Association of Securities Dealers, Inc.
 
As compensation for the investment advice and overall management, the Fund will
pay the Adviser a monthly fee, accrued daily, based on an annual rate of .5% of
the average daily net asset value 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.
 
ACCOUNTING SERVICES AND TRANSFER AGENT
 
The Fund has entered into an Accounting Services Agreement with the Adviser
pursuant to which the Adviser has agreed to maintain and keep current the books,
accounts, records, journals and other records of original entry relating to the
business of the Fund and to calculate the Fund's net asset value on a daily
basis. In consideration of such services, the Fund has agreed to pay the Adviser
a fee monthly based on the average monthly net asset value of the Fund.
 
The Fund has also entered into an Administration Agreement with the Adviser
pursuant to which the Adviser has agreed to act as the Fund's transfer agent and
dividend disbursing agent. In consideration of
 
                                       17
<PAGE>   70
 
such services the Fund has agreed to pay the Adviser an annual fee, paid
monthly, equal to $21 per shareholder account, plus the Adviser's out-of-pocket
expenses.
 
DISTRIBUTOR
 
The Fund 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
continuously will be offered on a best efforts basis by The Ohio Company and
dealers selected by The Ohio Company. H. Keith Allen is an officer and
trustee/director of both the Fund and The Ohio Company. Frank W. Siegel is an
officer and trustee of the Fund and an officer of The Ohio Company. James M.
Schrack II is an officer of both the Fund and The Ohio Company.
 
CUSTODIAN
 
The Fund 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.

ACH PROCESSING
 
The Fund now offers 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 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 Shares of the Fund for shares of:
 
        Cardinal Aggressive Growth Fund,
        an equity fund seeking appreciation of capital (upon the payment of the
        applicable sales charge);
 
        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);
 
        The Cardinal Fund Inc.,
        an equity fund seeking long-term growth of capital and income (upon the
        payment of the applicable sales charge);
 
        Cardinal Government Securities Trust,
        a U.S. Government securities money market fund (without payment of any
        sales charge); or
 
        Cardinal Tax Exempt Money Trust,
        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 Qualifying Plans, for whom The Ohio
Company serves as either a trustee or an investment adviser, of Fund Shares for
shares of a Cardinal Load Fund may be completed without the payment of a
 
                                       18
<PAGE>   71
 
sales charge, and (ii) exchanges of Fund Shares by all other shareholders for
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 shares of such Cardinal Load Fund and the sales charge previously
paid on the Fund Shares to be exchanged.
 
The foregoing exchange privilege may be exercised only once in each calendar
quarter and 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. Cardinal Management Corp., as 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 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
the Fund by telephone. Neither 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.
 
For tax purposes, an exchange is treated as a redemption and a new purchase.
However, a shareholder may not include any sales charge on Shares of the Fund
for purposes of calculating the gain or loss realized upon an exchange of those
Shares within 90 days of their purchase.
 
The Fund may, at any time, modify or terminate the foregoing exchange privilege.
The Fund, however, will give shareholders of the Fund 60 days' advance written
notice of any such modification or termination.
 
- - --------------------------------------------------------------------------------
WHAT ARE MY RIGHTS AS A SHAREHOLDER?
- - --------------------------------------------------------------------------------
 
Shares of the Fund, upon their issuance, are fully paid and nonassessable, are
of one class equal to all other Shares and are without par value. Certificates
representing Shares will not be issued unless specifically requested in writing
upon subscription. Ownership records of Shares will be maintained by the Fund's
transfer agent, Cardinal Management Corp.
 
Shareholders have equal voting rights on all matters submitted for shareholder
vote. The Declaration of Trust limits the matters requiring a shareholder vote
to the election or removal of Trustees, approval of certain contracts of the
Fund such as the Investment Advisory and Management Agreement with the Adviser
and the Distributor's Contract with The Ohio Company, approval of the
termination or reorganization of the Fund, approval of certain amendments to the
Declaration Of Trust and certain other matters described in such Declaration.
Under certain circumstances where Trustees have failed upon written request to
give notice of a meeting to consider matters requiring a shareholder vote,
shareholders holding at least 25% of the Fund's outstanding Shares may call and
give notice of such a meeting and thereafter a shareholder meeting will be held
to consider such matters.
 
- - --------------------------------------------------------------------------------
WHO PROVIDES SHAREHOLDER REPORTS?
- - --------------------------------------------------------------------------------
 
The Fund will provide shareholders monthly a summary statement describing any
purchases and sales of Shares of the Fund and dividend and capital gain
distributions.
 
Holders of Shares should direct all inquiries concerning such matters to
Cardinal Management Corp., 155 East Broad Street, Columbus, Ohio 43215.

                      STATEMENT OF ADDITIONAL INFORMATION


                     CARDINAL GOVERNMENT OBLIGATIONS FUND

         Cardinal Government Obligations Fund, known as Cardinal Government
Guaranteed Fund prior to February 1, 1991, (the "Fund") is a diversified,
open-end, management investment company.  The investment objective of the Fund
is 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 non-payment.

                      STATEMENT OF ADDITIONAL INFORMATION


                      CARDINAL GOVERNMENT OBLIGATIONS FUND

         Cardinal Government Obligations Fund (the "Fund") is an open-end
management investment company.  Much of the information contained in this
Statement of Additional Information expands upon subjects discussed in the
Prospectus of the Fund.  Capitalized terms not defined herein are defined in
the Prospectus.  No investment in Shares of the Fund should be made without
first reading the Prospectus of the Fund.


                       INVESTMENT OBJECTIVE 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.

         U.S. GOVERNMENT OBLIGATIONS.  The Fund 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.

         SECURITIES OF OTHER INVESTMENT COMPANIES.  The Fund may invest in
securities issued by other investment companies.  The 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 the
Fund.  As a shareholder of another investment company, the Fund would bear,
along with other shareholders, its pro rata portion of that company's expenses,
including advisory fees.  These expenses would be in addition to the advisory
and other expenses that the Fund bears directly in connection with its own
operations.  Investment companies in which the Fund may invest may also impose
a sales or distribution charge in connection with the purchase or redemption of
their shares and



                                      B-1
<PAGE>   80
other types of commissions or charges.  Such charges will be payable by the
Fund and, therefore, will be borne directly by shareholders.

         REPURCHASE AGREEMENTS.  Securities held by the Fund may be subject to
repurchase agreements.  Under the terms of a repurchase agreement, the 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 Fund'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).  If the seller were to default on its repurchase
obligation or become insolvent, the Fund would suffer a loss to the extent that
the proceeds from a sale of the underlying portfolio securities were less than
the repurchase price under the agreement, or to the extent that the disposition
of such securities by the Fund were delayed pending court action.
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 Fund 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 Fund if presented with the question.  Securities subject to repurchase
agreements will be held by the Fund's custodian or another qualified custodian
or in the Federal Reserve/Treasury book-entry system.  Repurchase agreements
are considered to be loans by the Fund under the 1940 Act.

         OPTIONS.  In order to maximize its total return, the Fund may from
time to time engage in the writing of call options on a national securities
exchange or in the over-the-counter market.  A call option gives its holder the
right to buy, and obliges the writer to sell, a specified underlying security
at a stated exercise price at any time prior to the option's expiration date.
The Fund will write only covered call options -- that is, the Fund will own the
securities subject to option throughout the period of its obligation as option
writer -- and will ordinarily write only options for which a secondary trading
market exists.  It will deposit the underlying security in escrow until the
exercise or expiration of the option (or such time as the Fund enters into a
closing purchase transaction).

         Options written by the Fund will normally have expiration dates
between one and six months from the date written.  The





                                      B-2
<PAGE>   81
exercise price of the options may be below ("in-the-money"), equal to
("at-the-money"), or above ("out-of-the-money") the current market values of
the underlying securities at the times the options are written.  The Fund may
engage in buy-and-write transactions, in which the Fund simultaneously
purchases a security and writes a call option thereon.  When a call option is
written against a security subsequent to the purchase of that security, the
resulting combined position is also referred to as a buy-and-write.
Buy-and-write transactions using in-the- money call options may be utilized
when it is expected that the price of the underlying security will remain flat
or decline moderately during the option period.  In such a transaction, the
Fund's maximum gain will be the premium received from writing the option
reduced by any excess of the price paid by the Fund for the underlying security
over the exercise price.  Buy-and-write transactions using at-the-money call
options may be utilized when it is expected that the price of the underlying
security will remain flat or advance moderately during the option period.  In
such a transaction, the Fund's gain will be limited to the premiums received
from writing the option.  Buy-and-write transactions using out- of-money call
options may be utilized when it is expected that the premiums received from
writing the call option plus the appreciation in the market price of the
underlying security up to the exercise price will be greater than the
appreciation in the price of the underlying security alone.  In any of the
foregoing situations, if the market price of the underlying security declines,
the amount of such decline will be offset wholly or in part by the premium
received and the Fund may or may not realize a loss.

         The writing of a covered call option will result in the payment of a
premium to the Fund.  If the value of the underlying security appreciates, it
is likely that the option holder will exercise its option and call the security
away from the Fund.  The Fund would then suffer an economic loss equal to the
excess, if any, of the underlying security's appreciation in value over the
premium it received for writing the option.

         When the Fund writes covered call options on GNMA Certificates, the
GNMA Certificates that it holds as cover may, because of scheduled amortization
or unscheduled prepayments, cease to be sufficient cover.  The Fund will
compensate by purchasing an appropriate additional amount of GNMA Certificates.

         The Fund may purchase put or call options on interest rate futures
contracts solely for the purpose of hedging against changes in the value of its
portfolio securities due to changes in interest rates.

         Options on interest rate futures contracts are similar to options on
securities, except that an option on an interest rate futures contract gives
the purchaser the right, in return for the premium paid, to assume a position
in an interest rate futures





                                      B-3
<PAGE>   82
contract (rather than to purchase securities) at a specified exercise price at
any time prior to the expiration date of the option.  A call option gives the
purchaser of such option the right to buy, and obliges its writer to sell, a
specified underlying futures contract at a stated exercise price at any time
prior to the expiration date of the option.  A purchaser of a put option has
the right to sell, and the writer has the obligation to buy, such contract at
the exercise price during the option period.  If an option is exercised on the
last trading day prior to the expiration date of the option, the settlement
will be made entirely in cash equal to the difference between the exercise
price of the option and the closing price of the interest rate futures contract
on the expiration date.  The potential loss related to the purchase of an
option on interest rate futures contracts is limited to the premium paid for
the option (plus transaction costs).  Because the value of the option is fixed
at the point of sale, there are no daily cash payments to reflect changes in
the value of the underlying contract; however, the value of the option does
change daily and that change is reflected in the net asset value of the Fund.

         The purchase of put options on interest rate futures contracts is
analogous to the purchase of protective puts on debt securities so as to hedge
a portfolio of debt securities against the risk of rising interest rates.  The
Fund may purchase put options on interest rate futures contracts if Adviser
anticipates a rise in interest rates.  Because of the inverse relationship
between trends in interest rates and the values of debt securities, a put
option on such a contract becomes more valuable as interest rates rise.  By
purchasing put options on interest rate futures contracts at a time when
Adviser expects interest rates to rise, the Fund would seek to realize a profit
to offset the loss in value of its portfolio securities, without the need to
sell such securities.

         The Fund may purchase call options on interest rate futures contracts
if Adviser anticipates a decline in interest rates.  Historically, unscheduled
prepayments on mortgage-backed securities (such as GNMA Certificates) have
increased in periods of declining interest rates, as mortgagors have sought to
refinance at lower interest rates.  As a result, were the Fund to purchase such
securities at a premium prior to a period of declining interest rates, the
subsequent prepayments at par would reduce the yield on such securities by
magnifying the effect of the premium in relationship to the principal amount of
securities, and might, under extreme circumstances, result in a loss to the
Fund.  This effect might not be offset by any appreciation in value in a debt
security normally attributable to the interest rate decline.  To protect itself
against the possible erosion of principal on securities purchased at a premium,
the Fund may purchase call options on interest rate futures.  The option would
increase in value as interest rates declined, thereby tending to offset any
reductions of the yield on portfolio securities purchased at a





                                      B-4
<PAGE>   83
premium resulting from the effect of prepayments on the amortization of such
premiums.

         The Fund may sell put and call options on interest rate futures only
as part of closing sales transactions to terminate its options positions.
There is no guarantee that such closing transactions can be effected.

         In addition to the risks that apply to all options transactions, there
are several special risks relating to options on interest rate futures
contracts.  The Fund's purchase of put or call options will be based upon
predictions of interest rate trends and predictions of the prepayment
experience of mortgage-backed securities, and such predictions may prove to be
inaccurate.  Even if such predictions are correct, there may be an imperfect
correlation between the change in the value of the options and of the Fund's
portfolio securities.

                 Company Act of 1940.

        The following additional investment restriction may be changed without

        The Fund may not:

         (1)     Purchase the 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.

         The Fund has represented to the California Department of Corporations
that, in order to comply with applicable regulations, it will acquire or retain
securities of other open-end management investment companies 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 Fund intends to comply with this
undertaking for so long as the Fund has its shares registered for sale in the
State of California or such representation is required by the California
Department of Corporations.





                                         B-7
<PAGE>   86
         The Fund has represented to the Ohio Division of Securities that it
will (1) not invest its assets in the securities of other investment companies,
except by purchase in the open market where no commission or profit to a
sponsor or dealer results from the purchase other than the customary broker's
commission, or except when the purchase is part of a plan of merger,
consolidation, reorganization, or acquisition; and (2) limit its investments to
15% of its total assets in securities of any issuer (a) which, together with
any predecessors, have a record of less than three years continuous operation
or (b) which are restricted as to disposition, including securities eligible
for resale under Rule 144A of the Securities Act of 1933.  The Fund intends to
comply with these representations for so long as its Shares are registered for
sale in the State of Ohio.

         If a percentage restriction or requirement set forth above is met at
the time of investment, a later failure to comply with the restriction or
requirement resulting from a change in the value of securities held by the Fund
will not be considered a violation of the policy.

Portfolio Turnover
- - ------------------
         The portfolio turnover rate for the Fund is calculated by dividing the
lesser of the Fund's purchases or sales of portfolio securities for the year by
the monthly average value of the portfolio securities.  The calculation
excludes all securities whose remaining maturities at the time of acquisition
were one year or less.

         The portfolio turnover rate for the Fund for the two fiscal years
ended September 30, 1995, and 1994, were 36.71% and 21.95%, respectively.  The
portfolio turnover rate for the Fund 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.

                             MANAGEMENT OF THE FUND

         The trustees and officers of the Fund, together with their addresses
and principal business occupations and other affiliations during the last five
years, are shown below.  Each person named as a trustee also serves as a
director or trustee of The Cardinal Fund Inc., Cardinal Government Securities
Trust, Cardinal Tax Exempt Money Trust and The Cardinal Group.  Each trustee
who is an "interested person" of the Fund, as that term is defined in the 1940
Act, is indicated by an asterisk.

         *During the fiscal year, John L. Schlater, a former officer of The
Ohio Company and the Adviser, and John R. Carle, the portfolio manager of the
Fund, each had served as trustees of the Fund but no longer do so as of the
date hereof.  Neither Mr. Schlater nor Mr. Carle received any compensation from
the Fund or the Fund Complex.

         **For purposes of this Table, Fund Complex means one or more mutual
funds, including the Fund, which have a common investment adviser or affiliated
investment advisers or which hold themselves out to the public as being
related.


                       PRINCIPAL SHAREHOLDERS OF THE FUND

         There were no persons known to the Fund to be the beneficial owners of
more than 5% of the Fund's outstanding Shares as of January 11, 1996.


                                  THE ADVISER

         The Fund has entered into an Investment Advisory and Management
Agreement (the "Investment Advisory Agreement") with Cardinal Management Corp.,
an Ohio corporation (the "Adviser"), 155 East Broad Street, Columbus, Ohio
43215, in which Adviser has agreed to serve as the Fund's investment adviser
and manager.  In such capacity, and subject to the ultimate authority of the
Fund's Board of Trustees, the Adviser has agreed regularly to provide the Fund
with investment advice, including management of the Fund's portfolio
securities, and overall management of the Fund's affairs.  The Adviser was
organized in March, 1980, and currently provides investment advisory services
to Cardinal Government Securities Trust, Cardinal Tax Exempt Money Trust,
Cardinal Balanced Fund and Cardinal Aggressive Growth Fund.  The Adviser is a
wholly-owned subsidiary of The Ohio Company, an Ohio corporation.  The Ohio
Company is an investment banking firm organized in 1925 and serves as the
principal underwriter for each of the foregoing funds and as the investment
adviser and principal underwriter for The Cardinal Fund Inc.  The Ohio Company
is a member of the New York Stock Exchange, Midwest Stock Exchange, other
regional stock exchanges and the National Association of Securities Dealers.

         The Adviser will be responsible for the payment of clerical and
shareholder service staff salary, office space and other office expenses, the
compensation and expenses of any persons rendering any services to the Fund who
are officers, directors, stockholders or employees of the Adviser or The Ohio
Company, and any advertising and promotion expenses.

        As compensation for the investment advice and overall management, the
Fund will pay the Adviser a monthly fee, accrued daily,


                                      B-12
<PAGE>   91
based on an annual rate of .5% of the daily net asset value of the Fund.  For
the fiscal years ended September 30, 1995, 1994 and 1993, the Adviser earned
$783,803, $947,139 and $972,887, respectively, under the Investment Advisory
Agreement.  In order to reduce the expenses of the Fund and to improve its
total return to shareholders, the Adviser, at its option may waive some part or
all of the fees to which it is entitled under its Investment Advisory Agreement
with the Fund.

         The Adviser has agreed to reimburse the Fund (up to the amount of the
fees received by the Adviser) for the aggregate expenses of the Fund during any
fiscal year which exceed the limits prescribed by any state in which the shares
of the Fund are registered for sale.  Currently, the most stringent limitation
provides that annual expenses of the Fund, including investment advisory and
management fees but excluding interest, taxes, brokerage commissions and
extraordinary expenses, shall not exceed two and one-half percent of the first
thirty million dollars of the Fund's average net assets, two percent of the
next seventy million dollars of the Fund's average net assets and one and
one-half percent of the Fund's remaining average net assets.


                             PORTFOLIO TRANSACTIONS

         Pursuant to the Investment Advisory Agreement, the Adviser, subject to
the policies established by the Board of Trustees of the Fund and in accordance
with the Fund's investment restrictions and policies, is responsible for the
Fund's portfolio decisions and the placing of the Fund's 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 in the
over-the-counter market are generally principal transactions with dealers.
With respect to the over-the-counter market, the Fund, 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 last three fiscal years ended September 30, 1995, the Fund
paid no brokerage commissions.

         In executing such transactions, the Adviser seeks to obtain the best
net results for the 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 


                                      B-13
<PAGE>   92
the prior sentence, the Fund will not necessarily be paying the lowest
commission or spread available.

         The Adviser may consider provision of research, statistical and other
information to the Fund or the Adviser in the selection of qualified
broker-dealers who effect portfolio transactions for the Fund so long as the
Adviser's ability to obtain the best net results for portfolio transactions of
the 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 the Fund.  Although this information
is useful to the Fund and the Adviser, 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 Fund under the Investment Advisory
Agreement.  The Fund 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.

         Investment decisions for the Fund are made independently from those
for any other investment company or account managed by the Adviser.  Any such
other investment company or account may also invest in the same securities as
the Fund.  When a purchase or sale of the same security is made at
substantially the same time on behalf of the Fund and another investment
company or account, the transaction will be averaged as to price, and available
investments will be allocated as to amount in a manner which the Adviser
believes to be equitable to the Fund and such other investment company or
account.  In some instances, this investment procedure may adversely affect the
price paid or received by the Fund or the size of the position obtained by the
Fund.  To the extent permitted by law, the Adviser may aggregate the securities
to be sold or purchased for the Fund with those to be sold or purchased for
other investment companies or accounts in order to obtain best execution.  In
making investment recommendations for the Fund, the Adviser will not inquire or
take into consideration whether an issuer of securities proposed for purchase
or sale by the Fund 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 Fund.

         The Fund did not during the fiscal year ended September 30, 1995, hold
securities of its regular brokers or dealers, as defined in Rule 10b-1 under
the 1940 Act, or their parent companies.


                                      B-14
<PAGE>   93
         Although the Fund does not intend to engage in short-term trading of
portfolio securities as a means of achieving its investment objective, it may
sell portfolio securities without regard to the length of time they have been
held whenever such sale will in the Adviser's opinion strengthen the Fund's
position and contribute to its investment objective.  Such could be the case
during periods of rapid fluctuations of interest rates in portfolio securities.


                              ACCOUNTING SERVICES

         The Fund has entered into an Accounting Services Agreement with the
Adviser pursuant to which the Adviser has agreed to maintain and keep current
the books, accounts, records, journals and other records of original entry
relating to the business of the Fund and to calculate the Fund's net asset
value on a daily basis.  In consideration of such services, the Fund has agreed
to pay monthly to the Adviser a fee based on the average monthly net asset
value of the Fund.  For the last three fiscal years ended September 30, 1995,
the Adviser received $40,879, $44,111 and $43,375, respectively, for services
to the Fund pursuant to such agreement.

         The Fund has entered into an Administration Agreement with the Adviser
pursuant to which the Adviser has agreed to act as the Fund's transfer agent,
dividend disbursing agent and administrator of plans for the Fund.  In
consideration of such services, the Fund has agreed to pay the Adviser an
annual fee paid monthly, equal to $21 per shareholder account plus the
Adviser's out-of-pocket expenses.  For the last three fiscal years ended
September 30, 1995, the Adviser received $174,394, $211,560 and $209,799,
respectively, for services to the Fund pursuant to such agreement.


                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

         The Fund's Shares may be purchased at the public offering price
through The Ohio Company, principal underwriter of the Fund's Shares, at its
address and number set forth on the cover page of this Statement of Additional
Information, and through other broker-dealers who are members of the National
Association of Securities Dealers, Inc. and have sales agreements with The Ohio
Company.

         Based upon the value of the Fund's portfolio securities and other
assets and the number of outstanding Shares as of the fiscal year end September
30, 1995, the net asset value and redemption price per share was $8.18.  The
total offering price per share was $8.57 per share (net asset value / .9550,
assuming the then current


                                      B-15
<PAGE>   94
maximum sales charge of 4.50% of the offering price).  The total offering price
is reduced on sales of $100,000 or more.

         The net asset value of the Fund is determined once daily as of 4:00
P.M., Columbus, Ohio time, (a) on each business day the New York Stock Exchange
is open for business and on any other day there is sufficient trading in the
Fund's portfolio securities that the Fund's net asset value per share might be
materially affected by changes in the value of its portfolio securities.  The
net asset value per share 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) minus all
liabilities (including estimated accrued expenses) by the total number of
shares then outstanding.

         Portfolio securities for which over-the-counter 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 Fund.

         The Fund may suspend the determination of the net asset value, 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 Securities and Exchange
Commission, (b) the Exchange is closed for other than customary weekend and
holiday closings, (c) an emergency exists as a result of which (i) disposal of
portfolio securities owned by the Fund is not reasonably practical or (ii) it
is not reasonably practical for the Fund to determine the fair value of its net
assets, or (d) the Securities and Exchange Commission has by order permitted
such suspension.


                                     TAXES

         The Fund intends to qualify as a "regulated investment company" under
the Code for so long as such qualification is in the best interest of the
Fund's shareholders.  In order to qualify as a regulated investment company,
the 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 stock,
securities, or currencies; derive less than 30% of its gross income from the
sale or other disposition of stock, 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, the Fund


                                      B-16
<PAGE>   95
must distribute to its shareholders at least 90% of its investment company
taxable income for the year.  In general, the 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, the
Fund would be subject to a non-deductible excise tax equal to 4% of the
deficiency.

         Although the Fund expects to qualify as a "regulated investment
company" and to be relieved of all or substantially all federal income taxes,
depending upon the extent of its activities in states and localities in which
its offices are maintained, in which its agents or independent contractors are
located, or in which it is otherwise deemed to be conducting business, the Fund
may be subject to the tax laws of such states or localities.  In addition, if
for any taxable year the Fund does not qualify for the special tax treatment
afforded 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 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.

         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.

         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


                                      B-17
<PAGE>   96
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 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 capital losses 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.  The 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 the Fund for its taxable year that qualifies for the dividends
received deduction.

         The 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 Prospectus 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 the Fund.  No attempt has been made to present a detailed
explanation of the federal income tax treatment of the Fund or its shareholders
and this discussion is not intended as a substitute for careful tax planning.
Accordingly, potential purchasers of Shares of the Fund are urged to consult
their tax advisers with specific reference to their own tax situation.  In
addition, the tax discussion in the Prospectus and this Statement of Additional
Information is based on





                                      B-18
<PAGE>   97
tax laws and regulations which are in effect on the date of the Prospectus and
this Statement of Additional Information; such laws and regulations may be
changed by legislative or administrative action.

         Shareholders should consult their tax advisers to assess the general
state and local tax consequences of investing in the Fund and, in particular,
to determine whether dividends paid that represent interest derived from U.S.
government securities is exempt from applicable state and local income taxes.


                            PERFORMANCE INFORMATION

         For the 30-day period ended September 30, 1995, the Fund's yield was
6.40%.  Such yield is computed by dividing the net investment income per Share
earned during that period by the maximum offering price per Share on the last
day of the period, according to the following formula:

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

         Where:  a = dividends and interest earned during the period; b =
expenses accrued for the period (net of reimbursements); c = the average daily
number of Shares outstanding during the period that were entitled to receive
dividends; and d = the maximum offering price per Share on the last day of the
period.  Expenses accrued during the period include all recurring fees that are
charged to all Shareholder accounts in proportion to the length of the base
period and assuming the Fund's average account size.  The yield computation
assumes the then applicable maximum initial sales charge is deducted from the
investment in the Fund.

         For the one-year and five-year periods ended September 30, 1995, and
the period from the commencement of the Fund's operation (February 3, 1986) to
September 30, 1995, the average annual total returns for the Fund were 6.20%,
6.46%, and 7.27%, respectively. For the one- and five-periods ended September
30, 1995, and the period from commencement of the Fund's operations (February
3, 1986) to September 30, 1995, the cumulative return figures for the Fund were
6.20%, 36.75% and 96.91%, respectively.  Each quotation of average annual total
return was 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 the Fund 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 over which total


                                      B-19
<PAGE>   98
return is being calculated and ERV = ending redeemable value of the
hypothetical $1,000 initial payment at the end of the period for which average
annual total return is being calculated assuming a complete redemption.  The
calculation of average annual total return assumes the deduction of the then
applicable 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 the Fund's average account size. Cumulative return is computed by
using average annual 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 the Fund's Prospectus, from time to time
the Fund may include in its sales literature and shareholder reports a quote of
a current "distribution" rate.  For the 12-month period ended September 30,
1995, the Fund's distribution rate was 7.24%.  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.

         Investors may also judge the performance of the Fund by comparing its
performance to the performance of other mutual funds or mutual fund portfolios
with comparable investment objectives and policies through various mutual fund
or market indices 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,
Consumer Reports and U.S.A. Today.  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

NOTES TO FINANCIAL STATEMENTS

SEPTEMBER 30, 1995
 
(1) -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Cardinal Government Obligations Fund (the "Fund") is a diversified, open-end
investment company created under the laws of Ohio by a Declaration of Trust
dated November 15, 1985 and is registered under the Investment Company Act of
1940. The following is a summary of significant accounting policies followed by
the Fund in the preparation of its financial statements. The policies are in
conformity with generally accepted accounting principles for investment
companies.
 
Security Valuation -- Portfolio securities for which over-the-counter market
quotations are readily available are valued at the bid price. If no quotations
are available, portfolio securities are valued in good faith by the Board of
Trustees of the Fund to reflect their fair value.
 
Security Transactions and Investment Income -- Security transactions are
recorded on the trade date. Interest income is recorded on the accrual basis.
Premiums and discounts are recognized as realized gains or losses from security
transactions as securities are sold or as principal reductions are received. In
determining the net realized gain or loss on securities sold, the cost of the
securities has been determined on first-in, first-out (FIFO) cost basis.
 
Federal Income Taxes -- No provision has been made for Federal taxes on the
Fund's income, since it is the policy of the Fund to comply with the provisions
of the Internal Revenue Code applicable to regulated investment companies and to
make sufficient distributions of taxable income and capital gains within the
required time to relieve it from all, or substantially all, Federal income
taxes.
 
Dividends to Shareholders -- Dividends are declared and accrued daily and (for
those shareholders not electing cash distribution of dividends) automatically
reinvested monthly, at net asset value, in additional shares of the Fund.
 
(2) -- PURCHASES AND SALES OF SECURITIES
 
Purchases and sales of U.S. government agency obligations (excluding short-term
obligations) during the year ended September 30, 1995 aggregated $57,596,492 and
$60,730,057, respectively.
 
As of September 30, 1995, gross unrealized gains and gross unrealized losses on
investment securities were $2,136,800 and $1,012,380, respectively; resulting in
a net unrealized gain of $1,124,420 on investment securities with a cost basis
of $152,786,945.
 
(3) -- TRANSACTIONS WITH AFFILIATES
 
As investment manager for the Fund, Cardinal Management Corp. (CMC), an
affiliated company, is allowed an annual fee of 0.5% of the average daily net
assets of the Fund. CMC has agreed that if the aggregate expenses of the Fund,
as defined, for any fiscal year exceed the expense limitation of any state
having jurisdiction over the Fund, CMC will refund to the Fund, or otherwise
bear, such excess. This limitation did not affect the calculation of the
management fee during the year ended September 30, 1995.
                                                                     (continued)

SEPTEMBER 30, 1995
 
CMC also serves the Fund as transfer agent and fund accountant. Transfer agent
service fees are based on a monthly charge per shareholder account plus
out-of-pocket expenses. Accounting service fees are based on the monthly average
net assets of the Fund. For the year ended September 30, 1995 the Fund paid or
accrued $174,394 and $40,879 for transfer agent and fund accounting services,
respectively.
 
The Ohio Company, sole shareholder of CMC, acting as distributor for the Fund,
reported that it received commissions after discounts to dealers from the sale
of shares of the Fund of $147,536 for the year ended September 30, 1995.
 
(4) -- COMMITMENTS AND CONTINGENCIES
 
The Fund has an available $5,000,000 line of credit with its custodian, Fifth
Third Bank, which was unused at September 30, 1995. When used, borrowings under
this arrangement are secured by portfolio securities and can be used only for
short term needs of the Fund. No compensating balances are required and the
arrangement bears an interest rate of 106% of the custodian's prime lending
rate.
 
Fidelity Bond and Errors and Omissions insurance coverage for the Fund and its
officers and trustees has been obtained through ICI Mutual Insurance Company
(ICI Mutual), an industry-sponsored mutual insurance company. Included in other
assets of the Fund is a deposit of $30,644, for the initial capital of ICI
Mutual. The Fund is also committed to provide $91,932 should ICI Mutual
experience the need for additional capital contributions.
 
Included in other assets is a $61,000 certificate of deposit which
collateralizes a standby letter of credit in connection with the Fund's
participation in ICI Mutual. This amount is not available for investment.
 
(5) -- CAPITAL STOCK
 
At September 30, 1995, there were an unlimited number of shares of no par value
capital stock authorized and the capital amounts were as follows:

For tax purposes, the accumulated net realized loss on investments (capital loss
carryforwards) of approximately $22,800,000 expire throughout the next eight
years. Approximately $3,800,000 of capital loss carryforwards expired during the
year ended September 30, 1995. The Fund will not declare any capital gain
distributions until the carryforwards have been offset or expired.

(6) -- SUBSEQUENT EVENT
 
On November 13, 1995 the Board of Trustees approved an Agreement and Plan of
Reorganization and Liquidation between the Fund and The Cardinal Group ("TCG").
The plan calls for the transfer of all assets and liabilities of the Fund to a
series of TCG with the same basic investment objectives and restrictions. The
Trustees have determined that this action is in the best interests of the
shareholders of the Fund and TCG. Shareholder approval will be sought and is
needed to ratify the transaction.

INDEPENDENT AUDITORS' REPORT

The Shareholders and Board of Trustees
Cardinal Government Obligations Fund:
 
We have audited the accompanying statement of assets and liabilities of Cardinal
Government Obligations Fund (the Fund), including the statement of investments,
as of September 30, 1995, and the related statement of operations for the year
then ended, the statements of changes in net assets for each of the years in the
two-year period then ended and the financial highlights for each of the years in
the five-year period then ended. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included verification of securities owned as of
September 30, 1995, by confirmation with the custodian and other appropriate
audit procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Cardinal Government Obligations Fund as of September 30, 1995, the results of
its operations for the year then ended, the changes in its net assets for each
of the years in the two-year period then ended, and the financial highlights for
each of the years in the five-year period then ended, in conformity with
generally accepted accounting principles.

                      CARDINAL GOVERNMENT SECURITIES TRUST
 
Cardinal Government Securities Trust (the "Trust") is a no-load, diversified,
open-end management investment company with an investment objective of
maximizing current income while preserving capital and maintaining liquidity.
The Trust seeks to attain its objectives by investing 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. All obligations purchased by the Trust will mature in thirteen
months or less. There can be no assurance that the Trust's objective will be
achieved.
 
THE SHARES OF THE TRUST ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR
ENDORSED BY ANY BANK, NOR ARE SUCH SHARES FEDERALLY INSURED OR GUARANTEED BY THE
U.S. GOVERNMENT, THE FEDERAL DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE
BOARD OR ANY OTHER GOVERNMENTAL AGENCY. AN INVESTMENT IN THE TRUST INVOLVES
CERTAIN INVESTMENT RISKS, INCLUDING THE POSSIBLE LOSS OF PRINCIPAL. THE TRUST
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.
 
The Trust has entered into an Agreement and Plan of Reorganization and
Liquidation, dated as of December 1, 1995 (the "Plan"), with The Cardinal Group,
an Ohio business trust (the "Group"). Pursuant to the Plan, Cardinal Government
Securities Money Market Fund, a series of the Group (the "Acquiring Fund"),
would acquire all of the assets of the Trust in exchange for the assumption of
all of the Trust's liabilities and a number of full and fractional shares of the
Acquiring Fund having an aggregate net asset value equal to the Trust's net
assets (the "Reorganization"). The Trust would then be liquidated, and the
shares of the Acquiring Fund would be distributed to Trust shareholders.
 
The Reorganization is subject to certain regulatory approvals and to approval by
the shareholders of the Trust at the Annual Shareholders Meeting currently
expected to be held in March, 1996. If the shareholders approve the
Reorganization, it is expected that the Reorganization would be effected on or
about March 31, 1996; however, the Reorganization may be effected on such
earlier or later date as the Group and the Trust may determine. There can be no
assurance that the Reorganization will take place when or as currently proposed.

HIGH CURRENT YIELD............. The Trust seeks the maximum yield available through
                                investment in short-term U.S. Government securities. (See
                                pages 6 and 7.)
HIGH DEGREE OF SAFETY.......... The investor obtains a high degree of safety due to the
                                fact the Trust invests solely in obligations issued or
                                guaranteed by the U.S. Government and its agencies and
                                instrumentalities, including U.S. Government obligations
                                subject to repurchase agreements. (See pages 6 and 7.)
MONTHLY DISTRIBUTIONS.......... Monthly distributions are automatically reinvested in
                                additional shares of the Trust without charge or may be
                                received in cash. (See pages 4 and 10.)
INSTANT LIQUIDITY.............. Through the free check writing privilege or telephone
                                transfer of funds, all or part of an investor's shares may
                                be redeemed on any business day at the net asset value
                                without charge. (See pages 12 and 13.)
LOW INITIAL INVESTMENT......... An investor can acquire shares of a high quality portfolio
                                of government securities with a smaller investment than
                                would be needed to purchase a similar portfolio directly.
                                (See page 8.)
PROFESSIONAL MANAGERS.......... The Trust's portfolio is fully managed by professional
                                portfolio managers. (See page 14.)
FLEXIBILITY.................... You may switch once each calendar quarter from one mutual
                                fund to another within the Cardinal Group of Funds as your

                                certain circumstances, however, a sales charge may be im-
                                posed on exchanges for shares of The Cardinal Fund Inc.,
                                Cardinal Government Obligations Fund, Cardinal Balanced
                                Fund and Cardinal Aggressive Growth Fund. (See pages 15
                                and 16.)
MAXIMUM YIELD.................. As there is no sales charge to reduce the yield, investors
                                receive the maximum yield on their investment. Service
                                fees and charges have not been considered. (See pages 8
                                and 14.)

                                processing for subsequent purchases of shares,
                                redemptions, and/or distributions paid. (See page 15.)

From time to time the Trust may advertise its "yield" or "annualized yield" and
its "effective yield". BOTH YIELD FIGURES ARE BASED ON HISTORICAL EARNINGS AND
ARE NOT INTENDED TO INDICATE FUTURE PERFORMANCE. The "yield" or "annualized
yield" of the Trust refers to the income generated by an investment in the Trust
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 Trust 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.
 
Investors may also judge the performance of the Trust 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. and Standard &
Poor's Corporation and to data prepared by Lipper Analytical Services, Inc. and
CDA Investment Technologies, 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 Trust that appears in a
publication such as those mentioned above may be included in advertisements and
in reports to shareholders.
 
- - --------------------------------------------------------------------------------
WHAT IS THE TRUST?
- - --------------------------------------------------------------------------------
 
The Trust is a diversified, open-end management investment company established
under Pennsylvania law by a Declaration of Trust dated March 21, 1980. The
Declaration of Trust, as amended to date, permits the Trustees to issue an
unlimited number of full and fractional shares of beneficial interest, all of
one class, with par value of $.01 per share, and authorizes the Trustees to
issue separate series of shares differing only in certain specified respects.
The Trustees have not currently authorized separate series of shares. Each Share
offered hereunder represents an equal pro rata interest in the Trust's common
portfolio. Upon liquidation, shareholders are entitled to share pro rata in the
net assets of the Trust available for distribution to shareholders. Shares are
freely transferable, have no preemptive or conversion rights and are redeemable
as set forth herein under "HOW MAY I REDEEM MY SHARES?" Shares are fully paid
and nonassessable, except as set forth under "SHAREHOLDER AND TRUSTEE LIABILITY"
in the Statement of Additional Information. Any additional series of shares must
be issued in compliance with the Investment Company Act of 1940 and must not
constitute a security that is senior to the Shares offered pursuant to this
Prospectus.
 
- - --------------------------------------------------------------------------------
WHAT ARE THE INVESTMENT OBJECTIVE AND POLICIES OF THE TRUST?
- - --------------------------------------------------------------------------------
 
The investment objective of the Trust is to maximize current income while
preserving capital and maintaining liquidity. There can be no assurance that the
objective of the Trust will be achieved. The investment objective with respect
to the Trust is a fundamental policy and as such may not be changed without a
vote of the holders of a majority of the outstanding Shares of the Trust.
 
6
<PAGE>   117
 
The Trust seeks to attain its investment objective by investing 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 Trust will not invest in contracts for forward delivery of
securities (so-called "futures"). The Trust will purchase only obligations
having maturities, from the date of purchase, of 13 months 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.
 
Notwithstanding any of the foregoing, the Trust, as a money market fund subject
to Rule 2a-7 of the Investment Company Act of 1940 (the "1940 Act"), must invest
exclusively in United States dollar-denominated instruments which the Trustees
of the Trust and the Trust's investment 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 ("NRSRO") (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
deemed to be of comparable quality. In addition, the dollar-weighted average
maturity of the obligations in the Trust may not exceed 90 days.
 
Subject to the foregoing limitations and in order to achieve its investment
objective, the Trust 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 a maturity of one year or less; Treasury notes
have maturities of one to ten years and Treasury bonds generally have 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 Trust intends to invest in variable and floating rate
instruments whose market value, upon reset of the interest rate, will
approximate par value 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 Trust will invest in such
securities only when it is satisfied that the credit risk with respect to the
issuer is minimal.
 
A repurchase agreement is an instrument under which the purchaser acquires
ownership of the obligation but the seller agrees, at the time of the sale, to
repurchase the obligation at a specified time and price. Although the securities
subject to a repurchase agreement might bear maturities of more than one year,
the settlement date for repurchase agreements entered into by the Trust cannot
be more than seven days after the date of purchase. 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 purchased security. Under the
1940 Act, repurchase agreements are considered to be loans by the Trust. The
Trust will only enter into a repurchase agreement where (i) the underlying
securities are of the type which the Trust's investment guidelines
 
                                                                             7
<PAGE>   118
 
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 custodian or a bank acting as agent. The Adviser
will be responsible for continuously monitoring such requirements. In the event
of a bankruptcy or other default of a seller of a repurchase agreement, the
Trust could experience both delays in liquidating the underlying securities and
losses, including: (a) possible decline in the value of the underlying security
during the period while the Trust 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.
 
The Trust 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 Trust intends to invest for purposes of short-term cash
management in other money market mutual funds. The Trust'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 Trust's investments in other investment companies, see
"INVESTMENT OBJECTIVES AND POLICIES -- Additional Information on Portfolio
Instruments --Securities of Other Investment Companies" in the Trust's Statement
of Additional Information.
 
The Trust cannot borrow money except from banks for temporary or emergency
non-investment purposes, such as to accommodate abnormally heavy redemption
requests, and then only in an amount not exceeding 10% of the value of the
Trust's total assets at the time of borrowing. The Trust cannot pledge, mortgage
or hypothecate its assets except to secure borrowing for temporary or emergency
non-investment purposes and then only in an amount not exceeding the lesser of
any applicable limitation under state law or 15% of its assets.
 
The Trust's investment objective and fundamental policies may not be changed
without approval of holders of a majority of the outstanding Shares of the
Trust.
 
- - --------------------------------------------------------------------------------
HOW DO I PURCHASE SHARES OF THE TRUST?
- - --------------------------------------------------------------------------------
 
Shares of the Trust 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 Trust's 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 Trust 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 Trust 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
Trust or by The Ohio Company.
 
Each new investor must complete an Application Form and send it to the Trust at
the indicated address either prior to or concurrently with the transmittal of
funds by wire or mail.
 
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. The Trust 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 ("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 Business Day, then the
purchase will be entered as of 4:00 p.m. Eastern Time on that day and dividends
will
 
8
<PAGE>   119
 
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 Trust reserves the right to reject any order to purchase its Shares.
Certificates representing Shares of the Trust will not be issued. All Shares
purchased are confirmed to the investor and credited to the investor's account
on the Trust's books maintained by Cardinal Management Corp. The investor will
have the same rights and ownership with respect to such Shares as if
certificates had been 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 Trust. 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 the Trust 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 Trust. 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
Trust'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
Trust or its shareholders.
 
PURCHASE BY FEDERAL FUNDS WIRE
 
Investments in Shares of the Trust 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 Trust at (800) 282-9446, toll
free, prior to wire transfer of its investment to advise the Trust of the
investment and, if a new investor, to obtain an account number. If an investor
does not telephone the Trust 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: Cardinal Government Securities Trust
                            [Include Trust Account Number and Name of Account
                            Holder]
 
Funds transmitted by wire will be invested in Shares of the Trust at the net
asset value next computed after receipt thereof as follows. Investment will
occur on the same day as the transfer of funds so long as federal funds are
received by The Ohio Company prior to 12:00 noon Eastern Time on any Business
Day. Federal funds received by The Ohio Company after 12:00 noon Eastern Time
will not be invested until the next Business Day. Dividends will accrue on the
day a purchase is effected only if federal funds are received by The Ohio
Company by 12:00 noon Eastern Time. A bank may charge for its services in
effecting wire transfers of funds.
 
Subsequent purchases of Shares of the Trust may be made by ACH processing as
described under "WHAT OTHER SHAREHOLDER PROGRAMS ARE PROVIDED? -- ACH
Processing" below.
 
                                                                            9

PURCHASE BY MAIL
 
Investment in Shares of the Trust may be made by mail by sending a check or
other negotiable bank draft payable to the order of "Cardinal Government
Securities Trust" together with, in the case of an initial purchase, an
Application Form to:
 
                       Cardinal Government Securities Trust
                       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 Trust
within one Business Day following receipt by The Ohio Company. Checks drawn on
non-member banks may take considerably longer. Cardinal Management Corp. or the
Trust will attempt to notify the investor upon receipt of the latter type of
check as to the possible delay and to arrange for a better means of transmittal
of funds. THE TRUST STRONGLY RECOMMENDS THAT INVESTORS OF SUBSTANTIAL AMOUNTS
USE FEDERAL FUNDS TO PURCHASE SHARES.
 
AUTOMATIC INVESTMENT PLAN
 
The Trust 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 the Trust on the
periodic basis you select. Confirmation of your purchase of Trust Shares will be
provided by the Trust. 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.

MAY MY TAX SHELTERED RETIREMENT PLAN INVEST IN THE TRUST?
- - --------------------------------------------------------------------------------
 
Shares of the Trust qualify for purchase in connection with the following tax
sheltered retirement plans:
 
     -- Individual retirement account ("IRAs") plans.
 
     -- Simplified Employee Pension Plans.
 
     -- 403(b)(7) Custodial Plans sponsored by certain tax-exempt employers.
 
     -- Pension, profit-sharing and 401(k) plans qualifying under Section 401(a)
        of the Internal Revenue Code.
 
- - --------------------------------------------------------------------------------
WHAT DISTRIBUTIONS WILL I RECEIVE?
- - --------------------------------------------------------------------------------
 
The Trust's net income is declared as a dividend and accrued on each Business
Day, immediately prior to the determination of the Trust's net asset value at
4:00 p.m. Eastern Time. Net interest income (from the time of the immediately
preceding declaration) consists of interest accrued on the portfolio of the
Trust (including accrued discount earned and premium amortized), plus realized
net short-term capital gains (losses) due to portfolio transactions (if any),
less the accrued expenses of the Trust applicable to that dividend period. The
Trust does not expect to realize any long-term capital gains due to its policy
of investing in securities maturing in 13 months or less.
 
All dividends of net income are credited to each shareholder's account daily and
automatically reinvested in additional Shares of the Trust at the net asset
value on the last Business Day of each month. Shareholders, however, may elect
to receive monthly the 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 Cardinal Management Corp. in writing. 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.
 
10
<PAGE>   121
 
Shareholders may elect to receive cash distributions by using ACH processing as
described under "WHAT OTHER SHAREHOLDER PROGRAMS ARE PROVIDED? -- ACH
Processing" below.
 
Should the Trust incur or anticipate any extraordinary expense or 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 the Trust's net
asset value per share were reduced, or expected to be reduced, below $1.00, the
Trustees might suspend further dividend accruals until the net asset value
returned to $1.00. Thus, extraordinary expenses or losses or depreciation may
result in no dividends being accrued for the period during which an investor
holds Shares as well as a redemption price lower than the purchase price for
such Shares.
 
- - --------------------------------------------------------------------------------
HOW MAY I REDEEM MY SHARES?
- - --------------------------------------------------------------------------------
 
Investors may redeem Shares of the Trust on any Business Day at the net asset
value next determined following receipt by the Trust's transfer agent, Cardinal
Management Corp., 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 Cardinal Management Corp. 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 Cardinal Management Corp. 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 Trust 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 Trust). The purchase of Trust
Shares by wire transfer of federal funds would avoid any such delay.
 
The Trust 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 Trust 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 to a
net asset value below $500. A shareholder will be notified in writing that the
value of the account is less than $500 and allowed not less than 30 days to
increase the account 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 elect to redeem Shares of the Trust by submitting a written
request therefor to Cardinal Management Corp., the Trust's transfer agent at 215
East Capital Street, Columbus, Ohio 43215. Cardinal Management Corp. 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
 
                                                                            11
<PAGE>   122
 
defined in the Securities Exchange Act of 1934. Cardinal Management Corp.
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 elect to redeem Shares of the Trust by calling the Trust 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 or
another address.
 
Neither the Trust 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 Trust's telephone redemption procedures, acting upon
instructions reasonably believed to be genuine. The Trust will employ procedures
designed to provide reasonable assurances that instructions by telephone are
genuine; if these procedures are not followed, the Trust 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
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 Trust 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 Trust 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 Trust's 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 Trust 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 Trust's Systematic Withdrawal Plan.
Please contact The Ohio Company for the appropriate form.

<PAGE>   123
 
CHECK-WRITING REDEMPTION PROCEDURE
 
Cardinal Management Corp., as Transfer Agent for the Trust, will provide any
shareholder who so requests with a supply of checks, imprinted with the
shareholder's name, which may be drawn against the Trust's account maintained by
The Fifth Third Bank (the "Bank"), for redemption of Trust Shares. These checks
may be made payable to the order of any person in any amount not less than $250.
To participate in this procedure, an investor must complete the Check-Writing
Redemption Form available from Cardinal Management Corp. When a check is
presented to the Bank for payment, Cardinal Management Corp. (as your agent)
will cause the Trust 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 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 Trust 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.
 
- - --------------------------------------------------------------------------------
HOW IS NET ASSET VALUE CALCULATED?
- - --------------------------------------------------------------------------------
 
The Trust's net asset value per share is currently determined as of 4:00 p.m.
Eastern Time on each Business Day, and on such other days on which there is a
sufficient degree of trading in the Trust's portfolio securities that the
Trust's net asset value might be materially affected by changes in the value of
the portfolio securities. Net asset value per share is computed by dividing the
total value of the assets of the Trust, less its liabilities, by the total
number of Shares outstanding. Expenses and fees of the Trust, 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 the Trust to use its best
efforts, under normal circumstances, to maintain a constant net asset value of
$1.00 per share. The Trust 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. The Trust will normally
include any accrued discount or premium in its daily dividend and will thereby
keep constant the value of the Trust'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.
 
- - --------------------------------------------------------------------------------
DOES THE TRUST PAY FEDERAL INCOME TAX?
- - --------------------------------------------------------------------------------
 
The Trust intends to qualify as a "regulated investment company" under the Code
for so long as such qualification is in the best interest of the Trust'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
Trust contemplates declaring as dividends 100% of the Trust'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
 
                                                                             13
<PAGE>   124
 
distributed during the next calendar year. If distributions during a calendar
year were less than the required amount, the Trust would be subject to a
nondeductible excise tax equal to 4% of the deficiency.
 
- - --------------------------------------------------------------------------------
WHAT ABOUT MY TAXES?
- - --------------------------------------------------------------------------------
 
It is expected that the Trust will distribute annually to shareholders all or
substantially all of the Trust'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 Trust and not in cash. Since
all of the Trust'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 Trust 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 Trust were to realize any long-term
capital gains, distribution by the Trust 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 Trust may be subject to state and local taxes with respect to their
ownership of Trust Shares or distributions from the Trust.
 
The foregoing is intended only as a brief summary of some of the important tax
considerations generally affecting the Trust and its shareholders. Potential
investors in the Trust 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.
 
Cardinal Management Corp. will inform shareholders at least annually of the
amount and nature of such income and capital gains.
 
- - --------------------------------------------------------------------------------
WHO MANAGES MY INVESTMENT IN THE TRUST?
- - --------------------------------------------------------------------------------
 
Pursuant to the laws of Pennsylvania and the Trust's Declaration of Trust, the
responsibility for the management of the Trust is vested in its Board of
Trustees which, among other things, is empowered by the Trust's Declaration of
Trust to elect officers of the Trust and contract with and provide for the
compensation of agents, consultants and other professionals to assist and advise
in such management.
 
INVESTMENT ADVISER AND MANAGER

 
The Adviser, located at 155 East Broad Street, Columbus, Ohio 43215, is a
wholly-owned subsidiary of The Ohio Company. The Adviser also acts as the
investment adviser to Cardinal Tax Exempt Money Trust ("CTEMT"), Cardinal
Government Obligations Fund ("CGOF"), Cardinal Balanced Fund ("CBF") and
Cardinal Aggressive Growth Fund ("CAGF") and as dividend and transfer agent for
The Cardinal Fund Inc., another open-end, diversified management investment
company ("CFI"), CTEMT, CGOF, CBF, CAGF and the Trust. The Ohio Company is a
member of the New York and Chicago Stock Exchanges, other regional exchanges and
the National Association of Securities Dealers, Inc. In addition to acting as
the principal underwriter for the Trust, CTEMT, CGOF, CBF and CAGF, The Ohio
Company acts as investment adviser and principal underwriter for CFI and as the
sponsor of various series of separate unit investment trusts.

 
Pursuant to the Investment Advisory Contract, the Adviser manages the investment
and reinvestment of the assets of the Trust in accordance with the Trust's
investment objective, policies and restrictions, subject to the general
supervision and control of the Trust's Board of Trustees. Since December 22,
1995, John R.
 
14
<PAGE>   125
 
Carle has been primarily responsible for the day-to-day management of the
Trust's portfolio. Mr. Carle has been a portfolio manager with the Adviser
and/or The Ohio Company since 1971 and has more than 28 years of investment
management experience.
 
The Adviser performs and bears the cost of research, statistical analysis and
continuous supervision of the investment portfolio of the Trust and furnishes
office facilities and certain clerical and administrative services to the Trust.
In addition, the Adviser bears all promotional expenses, including the costs of
printing and distributing prospectuses utilized for promotional purposes. All
other expenses are borne by the Trust.
 
For the year ended September 30, 1995, the Adviser received as compensation for
its investment advisory services .5% of average daily net assets of the Trust.
The Adviser has, however, and may in the future periodically waive all or a
portion of its advisory fee with respect to the Trust to increase the net income
of the Trust available for distributions as dividends. The waiver of such fee
will cause the yield of the Trust to be higher than it would otherwise be in the
absence of such waiver.

 
DIVIDEND AND TRANSFER AGENT AND FUND ACCOUNTANT
 
Cardinal Management Corp., 215 East Capital Street, Columbus, Ohio 43215, has
been selected to act as the Trust's Dividend and Transfer Agent. In
consideration of such services, the Trust has agreed to pay Cardinal Management
Corp. an annual fee, paid monthly, equal to $21 per shareholder account, plus
out-of-pocket expenses. Cardinal Management Corp. also provides fund accounting
services to the Trust and receives a fee from the Trust for such services.
 

DISTRIBUTOR
 
The Trust has entered into a Distributor's Contract with The Ohio Company, 155
East Broad Street, Columbus, Ohio 43215, pursuant to which Shares of the Trust
continuously will be offered on a best efforts basis by The Ohio Company and
dealers selected by The Ohio Company. H. Keith Allen is an officer and
trustee/director of both the Trust and The Ohio Company. Frank W. Siegel is an
officer and trustee of the Trust and an officer of The Ohio Company. James M.
Schrack II is an officer of both the Trust and The Ohio Company.

- - --------------------------------------------------------------------------------
WHAT OTHER SHAREHOLDER PROGRAMS ARE PROVIDED?
- - --------------------------------------------------------------------------------
 
ACH PROCESSING
 
The Trust now offers ACH privileges. Investors may use ACH processing to make
subsequent purchases, redeem Shares and/or electronically transfer distributions
paid on Trust 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
 
Investors 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 the Trust for shares of:
 
                                                                            15
<PAGE>   126
        Cardinal Tax Exempt Money Trust, 
        a tax-free money market fund
        (without payment of any sales charge);
 
        Cardinal Aggressive Growth Fund,
        an equity fund seeking appreciation of capital (upon the payment of 
        the applicable sales charge);
 
        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);
 
        The Cardinal Fund Inc.,
        an equity fund (upon payment of applicable sales charge); or
 
        Cardinal Government Obligations Fund,
        a U.S. Government bond fund (upon payment of applicable sales charge).
 
Notwithstanding the foregoing and subject to the limitations contained in the
following paragraph, exchanges of Trust Shares for shares of CFI, CGOF, CBF or
CAGF (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
shares of that Cardinal Load Fund. If, however, the Shares of Trust to be
exchanged were acquired as a result of an exchange of shares of the 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 may be exercised only once in each calendar
quarter and 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. Cardinal Management Corp., as 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 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
the Trust by telephone. Neither the Trust nor any of its service providers will
be liable of 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 Trust may, at any time, modify or terminate the foregoing exchange
privilege. The Trust, however, will give shareholders of the Trust 60 days
advance written notice of any such modification or termination.
 
- - --------------------------------------------------------------------------------
WHAT ARE MY RIGHTS AS A SHAREHOLDER?
- - --------------------------------------------------------------------------------
 
Each Share is entitled to one vote (and fractional shares to proportionate
fractional votes) in the election of Trustees and on other matters submitted to
the vote of shareholders. Voting rights are not cumulative, so that the holders
of more than 50% of the Shares voting in the election of Trustees have the power
to elect all of the Trustees of the Trust. Whenever the approval of a majority
of the outstanding Shares of the Trust is required in connection with
shareholder approvals of the Investment Advisory Contract, the Distribution
Contract or changes in the investment objective and policies or the investment
restrictions of the Trust, a "majority" shall mean the vote of (i) 67% or more
of the Shares of the Trust present at a meeting, if the holders of more than 50%
of the outstanding Shares are present in person or by proxy, or (ii) more than
50% of the outstanding Shares of the Trust, whichever is less.

                      STATEMENT OF ADDITIONAL INFORMATION


                      CARDINAL GOVERNMENT SECURITIES TRUST

         Cardinal Government Securities Trust (the "Trust") is an open-end
management investment company.  Much of the information contained in this
Statement of Additional Information expands upon subjects discussed in the
Prospectus of the Trust.  Capitalized terms not defined herein are defined in
the Prospectus.  No investment in Shares of the Trust should be made without
first reading the Prospectus of the Trust.


                       INVESTMENT OBJECTIVE AND POLICIES

General
- - -------

         The Trustees have adopted a policy requiring that the Trust use its
best efforts to maintain a constant net asset value of $1.00 per share.  The
Trust values its portfolio securities on the basis of the amortized cost
valuation method.  The valuation of the Trust's portfolio securities based upon
their amortized cost and the maintenance of the Trust's per share net asset
value of $1.00 is permitted based on the Trust's adherence to certain
conditions.  The Trust has agreed to maintain a dollar-weighted average
portfolio maturity of 90 days or less, in accordance with Rule 2a-7 of the 1940
Act, and purchase only obligations having, or deemed to have, maturities from
the date of purchase of thirteen months or less.  In addition, the Trustees
have agreed to establish procedures designed to stabilize, to the extent
reasonably possible, the Trust's per share price, as computed for the purpose
of sales and redemptions, at $1.00.  There is no assurance that the Trust will
at all times be able to maintain a constant net asset value of $1.00 per share.
(See "ADDITIONAL PURCHASE AND REDEMPTION INFORMATION -- Determination of Net
Asset Value.")

         Changes in short-term interest rates may affect the value of the
portfolio of the Trust.  An increase in interest rates will generally reduce
the value of the portfolio and a decline in interest rates will generally
increase the value of the portfolio.  The impact of such changes in prevailing
interest rates is generally minimized due to the short average life of the
portfolio and, under the investment policies described above, such interest
rate changes should not cause, under normal circumstances, changes in net asset
value per share.  If abnormally high redemption requests should require an
untimely sale of portfolio securities, the Trust intends to use its limited
borrowing powers to avoid such dispositions to the extent practicable.  (See
"Investment Restrictions" below.)

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

         REPURCHASE AGREEMENTS.  Securities held by the Trust may be subject to
repurchase agreements.  Under the terms of a repurchase agreement, the Trust
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 Trust's Board of Trustees, subject to the seller's agreement to
repurchase such securities at a mutually agreed-upon date and price.  The
repurchase price would generally equal the price paid by the Trust 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).  If the seller were to default on its repurchase
obligation or become insolvent, the Trust would suffer a loss to the extent
that the proceeds from a sale of the underlying portfolio securities were less
than the repurchase price under the agreement, or to the extent that the
disposition of such securities by the Trust were delayed pending court action.
Additionally, there is no controlling legal precedent confirming that the Trust
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 Trust believes that, under the regular procedures normally in
effect for custody of the Trust's securities subject to repurchase agreements
and under federal laws, a court of competent jurisdiction would rule in favor
of the Trust if presented with the question.  Securities subject to repurchase
agreements will be held by the Trust's custodian or another qualified custodian
or in the Federal Reserve/Treasury book-entry system.  Repurchase agreements
are considered to be loans by the Trust under the 1940 Act.

         SECURITIES OF OTHER INVESTMENT COMPANIES.  The Trust may invest in
securities issued by other investment companies.  The Trust 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 the
Trust.  As a shareholder of another investment company, the Trust would bear,
along with other shareholders, its pro rata portion of that company's expenses,
including advisory and other expenses that the Trust bears directly in
connection with its own operations.  Investment companies in which the Trust
may invest may also impose a distribution charge in connection with the
purchase or redemption of their shares and other types of commissions or
charges.  Such charges will be





                                      B-2
<PAGE>   135
payable by the Trust and, therefore, will be borne directly by shareholders.

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

         The Trust has adopted certain restrictions upon its investment
objective and policies which provide that the Trust may not:

         (1)     Purchase securities or make any investments other than those
                 described under "Investment Objective and Policies" in the
                 Prospectus (there is no limit upon the amount of the Trust's
                 assets which may be invested in the securities of any one
                 issuer of permitted obligations);
        
         (2)     Borrow money except from banks for temporary or emergency
                 non-investment purposes, such as to accommodate abnormally
                 heavy redemption requests, and then only in an amount not
                 exceeding 10% of the value of the Trust's total assets at the
                 time of borrowing; provided that so long as any borrowings
                 exceed 5% of the value of the Trust's total assets, the Trust
                 shall not purchase portfolio securities;

         (3)     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);

         (4)     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 objective and
                 policies;

         (5)     Effect short sales of securities;

         (6)     Act as an underwriter of securities;

         (7)     Enter into a repurchase agreement maturing in more than seven
                 days or knowingly purchase securities which are subject to
                 restrictions on resale or for which there is no readily

         (9)     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 securities
                 issued or guaranteed by the U.S. Government, its agencies or
                 instrumentalities.

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

         (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.

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

         The Trust has represented to the Ohio Division of Securities that it
will not invest any of its assets in the securities of other investment
companies, except by purchase in the open market where no commission or profit
to a sponsor or dealer results from the purchase other than the customary
broker's commission, or except when the purchase is part of a plan of merger,
consolidation, reorganization, or acquisition.

         If a percentage restriction is adhered to at the time the relevant
action is taken, a later increase or decrease in percentage resulting from a
change in market value of an investment or in total assets will not be deemed
to result in a violation of the restriction.

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

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


                                      B-4
<PAGE>   137
         Because the Trust intends to invest almost 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 the Trust is expected to be zero percent for
regulatory purposes.


                            MANAGEMENT OF THE TRUST

         The trustees and officers of the Trust, together with their addresses

         *During the fiscal year ended September 30, 1995, Hannibal L. Godwin,
a former officer of the Trust, and John L. Schlater, each former officers of
The Ohio Company and the Adviser, had served as trustees of the Trust but no
longer do so as of the date hereof.  Neither Mr.  Godwin nor Mr. Schlater
received any compensation from the Trust or the Fund Complex.

         **For purposes of this Table, Fund Complex means one or more mutual
funds, including the Trust, which have a common investment adviser or
affiliated investment advisers or which hold themselves out to the public as

                      PRINCIPAL SHAREHOLDERS OF THE TRUST

         As of January 11, 1996, the only person known to the Trust to be the
beneficial owners of more than 5% of the Trust's outstanding Shares was The
Ohio Company, which for its own account and as trustee for various pension
plans and trusts, owned beneficially 9.44% of the Trust's outstanding Shares.


                                  THE ADVISER

         The Trust has entered into an Investment Advisory Contract with
Cardinal Management Corp. (the "Adviser").  Pursuant to the Investment Advisory
Contract, the Adviser has agreed to provide investment advisory and management
services as described in the Prospectus. As compensation for such services to
the Trust, the Adviser receives monthly from the Trust a management fee at the
annual rate of 1/2 of 1% of the average daily net assets of the Trust.  Such
fee accrues daily.  The Adviser performs and bears the cost of research,
statistical analysis and continuous supervision of the investment portfolio of
the Trust and furnishes office facilities and certain clerical and
administrative services to the Trust.  In addition, the Adviser provides
dividend, transfer agency and fund accounting services to the Trust.

         The aggregate amount of investment management fees earned by the
Adviser during the fiscal years ended September 30, 1995, 1994 and 1993, was
$2,031,367, $1,978,541 and $2,227,209, respectively.  To offset capital losses
incurred by the Trust for the fiscal year ended September 30, 1994, the Adviser
contributed $1,151,168 to the Trust.  This amount was equal to the investment
management, transfer agent and fund accounting fees for the period from May 1,
1994, through September 30, 1994.

         The Adviser has agreed that if the aggregate expenses of the Trust
(including fees pursuant to the Investment Advisory Contract, but excluding
taxes, interest, brokerage fees and, where permitted under the expense
limitations imposed by state securities administrators, extraordinary expenses)
for any fiscal year exceed 2% of the first $10 million of the Trust's average
net assets, 1 1/2% of the next $30 million of the Trust's average net assets,
and 1% of the Trust's remaining average net assets, or 1 1/2% of average net
assets, whichever is less, the Adviser will refund to the Trust, or otherwise
bear, such excess.  The Adviser was not obligated to refund or pay any expenses
of the Trust for the fiscal years ended September 30, 1995, 1994 and 1993 as a
result of such expense limitations.

         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 an officer of The Ohio Company.

         The Investment Advisory Contract was last approved by a majority of
both the trustees and those trustees who are not "interested persons" (as
defined in the 1940 Act) of either the Trust or the Adviser at a meeting held
for such purpose on November 13, 1995, and was last approved by the
shareholders of the Trust at the annual meeting of shareholders of the Trust
held on January 11, 1983.


         The Investment Advisory Contract will continue in force from year to
year if specifically approved at least annually by the Board of Trustees of the
Trust or by the vote of a majority of the Trustees who are not "interested
persons" of any party to such Contract, cast in person at a meeting called for
such purpose.  The Contract may be terminated by either party, at any time,
without penalty, upon sixty days' written notice, and will automatically
terminate in the event of its assignment.  Termination will not affect the
right of the Adviser to receive payments on any unpaid balance of the
compensation earned prior to termination.

<PAGE>   142
                             PORTFOLIO TRANSACTIONS

         Pursuant to the Investment Advisory Contract, the Adviser, subject to
the policies established by the Board of Trustees of the Trust and in
accordance with the Trust's investment restrictions and policies, is
responsible for the Trust's portfolio decisions and the placing of the Trust's
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 in the
over-the-counter market are generally principal transactions with dealers.
With respect to the over-the-counter market, the Trust, 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.


         In executing such transactions, the Adviser seeks to obtain the best
net results for the Trust 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, the Trust will not necessarily be paying the lowest
commission or spread available. For the past three fiscal years, the Trust has
paid no brokerage commissions.


         The Adviser may consider provision of research, statistical and other
information to the Trust or the Adviser in the selection of qualified
broker-dealers who effect portfolio transactions for the Trust so long as the
Adviser's ability to obtain the best net results for portfolio transactions of
the Trust 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 the Trust. Although this information is useful
to the Trust and the Adviser, 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 Trust under the Investment Advisory Contract. The
Trust 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. 


                                      B-10
<PAGE>   143
         Investment decisions for the Trust are made independently from those
for any other investment company or account managed by the Adviser.  Any such
other investment company or account may also invest in the same securities as
the Trust.  When a purchase or sale of the same security is made at
substantially the same time on behalf of the Trust and another 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 Trust and such other investment company or
account.  In some instances, this investment procedure may adversely affect the
price paid or received by the Trust or the size of the position obtained by the
Trust.  To the extent permitted by law, the Adviser may aggregate the
securities to be sold or purchased for the Trust with those to be sold or
purchased 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 Trust, the Adviser will not inquire or take
into consideration whether an issuer of securities proposed for purchase or
sale by the Trust 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 Trust.

         The Trust did not during the fiscal year ended September 30, 1995,
hold any securities of its regular brokers or dealers, as defined in Rule 10b-1
under the 1940 Act, or their parent companies.


                              ACCOUNTING SERVICES

         The Trust has entered into an Accounting Services Agreement with the
Adviser pursuant to which the Adviser has agreed to maintain and keep current
the books, accounts, records, journals and other records of original entry
relating to the business of the Trust and to calculate the Trust's net asset
value on a daily basis.  In consideration of such services, the Trust has
agreed to pay monthly to the Adviser a fee based on the average monthly net
asset value of the Trust.  For the last three fiscal years ended September 30,
1995, the Adviser received $53,283, $54,818, and $59,614, respectively, for its
services to the Trust pursuant to such Agreement.  As described above under
"THE ADVISER," a portion of such fees for the fiscal year ended September 30,
1994 were contributed to the Trust by the Adviser.


                  TRANSFER AGENT AND DIVIDEND DISBURSING AGENT

         The Trust has entered into an Administration Agreement with the
Adviser pursuant to which the Adviser has agreed to act as the Trust's transfer
agent, dividend disbursing agent and administrator of plans for the Trust.  In
consideration of such services, the Trust has agreed to pay the Adviser an
annual fee paid monthly,


                                      B-11
<PAGE>   144
equal to $21 per shareholder account plus the Adviser's out-of-pocket expenses.
For the last three fiscal years ended September 30, 1995, the Adviser received
$842,187, $999,507, and $918,214, respectively, for its services to the Trust
pursuant to such Agreement.  As described above under "THE ADVISER," a portion
of such fees were contributed to the Trust by the Adviser.


                                  DISTRIBUTOR

         The Ohio Company, with principal offices located at 155 East Broad
Street, Columbus, Ohio 43215, serves as the Trust's principal underwriter and,
in connection therewith, is available to receive purchase orders and redemption
requests relating to Shares of the Trust and to transmit such orders and
requests to the Trust's custodian.  The Ohio Company does not receive any
compensation from the Trust or charge any fees to investors for its services
rendered as principal underwriter of the Trust's Shares.

         The Distribution Contract was last approved by both the trustees and
those trustees who are not "interested persons" (as defined in the 1940 Act) of
either the Trust or The Ohio Company at a meeting held for such purpose on
November 13, 1995, and was last approved by the shareholders of the Trust at
the annual meeting of shareholders of the Trust held on January 11, 1983.

         The Distribution Contract will continue in effect from year to year if
specifically approved at least annually by the Board of Trustees of the Trust
or by the vote of a majority of the outstanding Shares of the Trust.  In either
event, the Distribution Contract must also be approved by vote of a majority of
the trustees who are not "interested persons" of any party to the Distribution
Contract, cast in person at a meeting called for such purpose.  The
Distribution Contract will automatically terminate in the event of its
assignment.


                                   CUSTODIAN

         The Fifth Third Bank (the "Bank"), 38 Fountain Square, Cincinnati,
Ohio 45263, has been selected to act as Custodian of the portfolio securities
and cash of the Trust.  The Bank has no part in determining the investment
policies of the Trust or in deciding which securities are to be purchased or
sold by the Trust.  The Trust may enter into repurchase agreements with the
Bank and may purchase or sell securities from or to the Bank.

                     LEGAL COUNSEL AND INDEPENDENT AUDITORS

         Certain legal matters as to the issuance of the Shares offered hereby
have been passed upon by Baker & Hostetler, 65 East State Street, Columbus,
Ohio 43215.  The Trust has selected KPMG Peat Marwick LLP, Two Nationwide
Plaza, Columbus, Ohio 43215, as


                                      B-12
<PAGE>   145
independent auditors for the Trust.  The financial statements of the Trust
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

         The Trust's Shares may be purchased at the public offering price and
are sold on a continuous basis through The Ohio Company, principal underwriter
of the Trust's Shares, at its address and number set forth on the cover page of
this Statement of Additional Information, and through other broker-dealers who
are members of the National Association of Securities Dealers, Inc. and have
sales agreements with The Ohio Company.

         The Trust 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 Securities and Exchange Commission, (b) the Exchange is closed for other
than customary weekend and holiday closings, (c) the Securities and Exchange
Commission has by order permitted such suspension, or (d) an emergency exists
as a result of which (i) disposal by the Trust of securities owned by it is not
reasonably practical or (ii) it is not reasonably practical for the Trust to
determine the fair value of its net assets.

         Use of the check-writing redemption procedure will be subject to the
rules and regulations of The Fifth Third Bank (the "Bank") governing checking
accounts.  Neither the Bank nor the Trust 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 Trust, 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 purpose of
Federal Deposit Insurance or otherwise.

Determination of Net Asset Value
- - --------------------------------

         The Trust values its portfolio securities on the basis of the
amortized cost valuation method, which involves valuing an instrument at its
cost and thereafter assuming a constant amortization to maturity of any
discount or premium, regardless of the impact of fluctuating interest rates on
the market value of the instrument.  While this method provides certainty in
valuation, it may result in periods during which the value of the Trust's
portfolio securities, as determined by the amortized cost method, is higher or
lower than the price the Trust would receive if it





                                      B-13
<PAGE>   146
sold the securities.  During periods of declining interest rates, the daily
yield on Shares of the Trust computed as described above may tend to be higher
than a like computation made by a fund with market prices and estimates of
market prices for all of its portfolio securities.  Thus, if the use of the
amortized cost method by the Trust resulted in a lower aggregate portfolio
value on a particular day, a prospective investor in the Trust would be able to
obtain a somewhat higher yield than would result from investment in a fund
utilizing solely market values, and existing investors in the Trust would
receive less investment income.  The converse would apply in a period of rising
interest rates.

         The valuation of the Trust's portfolio securities based upon their
amortized cost and the maintenance of the Trust's per share net asset value of
$1.00 is permitted based on the Trust's 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 or
397 days or less.  The Trustees have also established procedures designed to
stabilize, to the extent reasonably possible, the Trust's net asset value per
share, as computed for the purpose of sales and redemptions, at $1.00.  Such
procedures include review of the Trust's portfolio holdings by the Trustees at
such intervals as they may deem appropriate to determine whether the Trust's
net asset value calculated by using available market quotations deviates from
$1.00 per share and, if so, whether such deviation is unfair to existing
shareholders.  In the event the Trustees determine that such a deviation
exists, they have agreed to take such corrective action as they deem necessary
and appropriate, including selling portfolio securities prior to maturity to
realize capital gains or losses or to shorten average portfolio maturity,
withholding dividends or establishing a net asset value per share by using
available market quotations instead of using the amortized cost basis.

                                     TAXES

Federal Taxes
- - -------------

         The Trust intends to qualify as a "regulated investment company" under
the Code for so long as such qualification is in the best interest of the
Trust's shareholders.  In order to qualify as a regulated investment company,
the Trust 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 stock,
securities, or currencies; derive less than 30% of its gross income from the
sale or other disposition of stock, 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, the Trust must
distribute to its shareholders at least 90% of its investment





                                      B-14
<PAGE>   147
company taxable income for the year.  In general, the Trust'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, the
Trust would be subject to a non-deductible excise tax equal to 4% of the
deficiency.

         Although the Trust expects to qualify as a "regulated investment
company" and to be relieved of all or substantially all federal income taxes,
depending upon the extent of its activities in states and localities in which
its offices are maintained, in which its agents or independent contractors are
located, or in which it is otherwise deemed to be conducting business, the
Trust may be subject to the tax laws of such states or localities.  In
addition, if for any taxable year the Trust 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 the Trust will distribute annually to shareholders
all or substantially all of the Trust'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 Trust and not in
cash.  The Trust 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 Trust were to realize any long-term capital
gains, distribution by the Trust 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.

         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





                                      B-15
<PAGE>   148
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 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 capital losses 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.  Because all of
the Trust's net investment income is expected to be derived from interest and
short-term capital gains, it is anticipated that no distributions from the
Trust will qualify for the dividends received deduction.  However, to the
extent the Trust would have any such distributions, the Trust 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 the
Trust for its taxable year that qualifies for the dividends received deduction.

         The Trust 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.

State and Local Taxes
- - ---------------------

         Shareholders of the Trust may be subject to state and local taxes with
respect to their ownership of Trust Shares or distributions from the Trust.
Under the laws of some jurisdictions, distributions of net investment income
may be





                                      B-16
<PAGE>   149
taxable to shareholders as dividend income even though a substantial portion of
such distributions may be attributable to interest on U.S.  Government
obligations which, if received directly, may be exempt from such income taxes.
Each shareholder should consult its tax adviser about the tax status of
distributions from the Trust in the relevant state and locality.

General
- - -------

         Information set forth in the Prospectus 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 the Trust.  No attempt has been made to present a detailed
explanation of the federal income tax treatment of the Trust or its
Shareholders and this discussion is not intended as a substitute for careful
tax planning.  Accordingly, potential purchasers of Shares of the Trust are
urged to consult their tax advisers with specific reference to their own tax
situation.  In addition, the tax discussion in the Prospectus and this
Statement of Additional Information is based on tax laws and regulations which
are in effect on the date of the Prospectus and this Statement of Additional
Information; such laws and regulations may be changed by legislative or
administrative action.

         Shareholders should consult their tax advisers to assess the general
state and local tax consequences of investing in the Trust and, in particular,
to determine whether dividends paid that represent interest derived from U.S.
government securities is exempt from applicable state and local income taxes.


                                     YIELD

         The current (average annualized) yield of the Trust for any seven-day
period is calculated by dividing the average daily net income per Share earned
by the Trust during the seven-day calendar period by the Trust'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 Trust's
portfolio.  The yield of the Trust for the seven-day period ended September 30,
1995, was 5.11%.

         The effective or compounded yield of the Trust for any seven-day
period is computed by adding the number one to the daily net income per Share
earned by the Trust during the seven-day calendar period, raising the sum to a
power equal to 365 divided by seven,


                                      B-17
<PAGE>   150
and subtracting the number one from the result.  The effective or compounded
yield of the Trust for the seven-day period ended September 30, 1995, was
5.24%.

         Investors may judge the performance of the Trust 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. and Standard
& Poor's Corporation, and to data prepared by Lipper Analytical Services, Inc.,
a widely recognized independent service which monitors the performance of
mutual funds, CDA Investment Technologies, Inc., and the Consumer Price Index.
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 Columbus Dispatch, The New York Times, Business Week, Consumer
Reports and U.S.A. Today.

         Current and effective yields will fluctuate from time to time and
should not be considered representative of future results.  Yield is a function
of general economic and money market conditions, portfolio quality and
maturity, type of portfolio instruments and operating expenses.  Yield
information may be useful in reviewing the Trust's performance and comparing an
investment in Shares of the Trust with other investment alternative.  However,
yield on Shares of the Trust fluctuates unlike yields on bank deposits or other
instruments that pay a fixed yield for a stated period of time.

                             ADDITIONAL INFORMATION

Shareholder and Trustee Liability
- - ---------------------------------

         The Trust is an entity of the type commonly known as a "business
trust."  Shareholders of such a trust may, under certain circumstances, be held
personally liable as partners for the obligations of the Trust.  The
Declaration of Trust provides that shareholders shall not be subject to any
personal liability for the acts or obligations of the Trust and that every
agreement, obligations or instrument entered into or executed by the Trust
shall contain a provision to the effect that the shareholders are not
personally liable thereunder.  The Trust has been advised by counsel that no
personal liability will attach to the shareholders when such a provision is
utilized, except possibly in a few jurisdictions.  With respect to all types of
claims, contract claims where shareholder liability is not negated, claims for
taxes and certain statutory liabilities, a shareholder may be held personally
liable for obligations of the Trust.  However, upon payment of any such
liability, the shareholder will be entitled to reimbursement from the general
assets of the Trust.  The Trust is


                                      B-18
<PAGE>   151
covered by insurance which the Trustees consider adequate to cover foreseeable
tort claims.  The Declaration of Trust provides for indemnification out of
Trust property of any shareholder held personally liable solely by reason of
his being or having been a shareholder.  The Declaration of Trust also provides
that the Trust shall, upon request, assume the defense of any claim made
against any shareholder for any act or obligation of the Trust and satisfy any
judgment thereon.  Thus, the risk of financial loss to a shareholder on account
of shareholder liability is limited to circumstances in which the Trust itself
would be unable to meet its obligations.

         The Declaration of Trust further provides that no Trustee, officer or
agent of the Trust shall be personally liable to any person for any action or
failure to act except for his own bad faith, willful misfeasance, gross
negligence or reckless disregard of his duties.  It also provides that all
persons having any claim against the Trustees or the Trust shall look solely to
the Trust's property for payment.  The Trust may enter into repurchase
agreements with the Bank and may purchase or sell securities from or to the
Bank.

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

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

         The Prospectus 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

CARDINAL GOVERNMENT SECURITIES TRUST
- - --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS
- - --------------------------------------------------------------------------------
 
SEPTEMBER 30, 1995
 
(1) -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Cardinal Government Securities Trust (the Trust) is a diversified, open-end
investment company created under the laws of Pennsylvania by a Declaration of
Trust dated March 21, 1980 and is registered under the Investment Company Act of
1940. According to the terms of the Declaration of Trust, Trust investments must
be obligations (or collateralized by obligations) of the U.S. Government or
agencies thereof. The following is a summary of significant accounting policies
followed by the Trust in the preparation of its financial statements. The
policies are in conformity with generally accepted accounting principles for
investment companies.
 
Security Valuation -- Securities are valued at amortized cost which approximates
fair value (premiums and discounts are amortized on a straight-line basis). The
use of this method requires the Trust to maintain a dollar-weighted average
portfolio maturity of 90 days or less and purchase only securities having a
remaining maturity of thirteen months or less.
 
Security Transactions and Investment Income -- Security transactions are
recorded on the trade date. Interest income is recorded on the accrual basis. It
is the Trust's policy for its Custodian or a third-party bank to take possession
of all securities pledged as collateral for repurchase agreements and monitor
the market value of the collateral to ensure that it remains sufficient to cover
the repurchase agreements.
 
Federal Income Taxes -- No provision has been made for Federal taxes on the
Trust's income, since it is the policy of the Trust to comply with the
provisions of the Internal Revenue Code applicable to regulated investment
companies and to make sufficient distributions of taxable income and capital
gains within the required time to relieve it from all, or substantially all,
Federal income taxes.
 
Dividends to Shareholders -- Dividends are declared and accrued daily and (for
those shareholders not electing cash distribution of dividends) automatically
reinvested monthly in additional shares from the sum of net investment income
and net realized short-term gains.
 
(2) -- TRANSACTIONS WITH AFFILIATES
 
As investment manager for the Trust, Cardinal Management Corp. (CMC), an
affiliated company, is allowed an annual fee of 0.5% of the average daily net
assets of the Trust. CMC has agreed that if the aggregate expenses of the Trust,
as defined, for any fiscal year exceed the expense limitation of any state
having jurisdiction over the Trust, CMC will refund to the Trust, or otherwise
bear, such excess. This limitation did not affect the calculation of the
management fee during the year ended September 30, 1995.
 
CMC also serves the Trust as transfer agent and fund accountant. Transfer agent
service fees are based on a monthly charge per shareholder account plus
out-of-pocket expenses. Accounting service fees are based on the monthly average
net assets of the Trust. For the year ended September 30, 1995 the Trust paid or
accrued $842,187 and $53,283 for transfer agent and fund accounting services,
respectively.
 
To offset capital losses incurred by the Trust, CMC contributed $1,151,186 to
the Trust during the year ended September 30, 1994. The amount contributed was
equal to the investment management, transfer agent service and the fund
accounting fees for the period from May 1, 1994 through September 30, 1994.
 
                                                                     (continued)

SEPTEMBER 30, 1995
 
The Ohio Company, sole shareholder of CMC, serves as the Trust's distributor
and, in connection therewith receives purchase orders and redemption requests
relating to Trust shares. During the year ended September 30, 1995 the Trust
incurred no expenses related to the distribution of its shares.
 
(3) -- COMMITMENTS AND CONTINGENCIES
 
The Trust has an available $6,000,000 line of credit with its custodian, Fifth
Third Bank, which was unused at September 30, 1995. When used, borrowings under
this arrangement are secured by portfolio securities and can be used only for
short term needs of the Trust. No compensating balances are required and the
arrangement bears an interest rate of 106% of the custodian's prime lending
rate.
 
Fidelity Bond and Errors and Omissions insurance coverage for the Trust and its
officers and trustees has been obtained through ICI Mutual Insurance Company
(ICI Mutual), an industry-sponsored mutual insurance company. Included in other
assets of the Trust is a deposit of $87,459 for the initial capital of ICI
Mutual. The Trust is also committed to provide $262,377 should ICI Mutual
experience the need for additional capital contributions.
 
Included in other assets is a $175,000 certificate of deposit which
collateralizes a standby letter of credit in connection with the Trust's
participation in ICI Mutual. This amount is not available for investment.

(5) -- SUBSEQUENT EVENT
 
On November 13, 1995 the Board of Trustees approved an Agreement and Plan of
Reorganization and Liquidation between the Trust and The Cardinal Group ("TCG").
The plan calls for the transfer of all assets and liabilities of the Trust to a
series of TCG with the same basic investment objectives and restrictions. The
Trustees have determined that this action is in the best interests of the
shareholders of the Trust and TCG. Shareholder approval will be sought and is
needed to ratify the transaction.

INDEPENDENT AUDITORS' REPORT
- - --------------------------------------------------------------------------------
 
The Shareholders and Board of Trustees
Cardinal Government Securities Trust:
 
We have audited the accompanying statement of assets and liabilities of Cardinal
Government Securities Trust (the Trust), including the statement of investments,
as of September 30, 1995, and the related statement of operations for the year
then ended, the statements of changes in net assets for each of the years in the
two-year period then ended and the financial highlights for each of the years in
the five-year period then ended. These financial statements and financial
highlights are the responsibility of the Trust's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included verification of securities owned as of
September 30, 1995, by confirmation with the custodian and other appropriate
audit procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Cardinal Government Securities Trust as of September 30, 1995, the results of
its operations for the year then ended, the changes in its net assets for each
of the years in the two-year period then ended, and the financial highlights for
each of the years in the five-year period then ended, in conformity with
generally accepted accounting principles.

                        CARDINAL TAX EXEMPT MONEY TRUST
 
Cardinal Tax Exempt Money Trust (the "Trust") is a no-load, diversified,
open-end management investment company. The Trust has an investment objective of
maximizing current income exempt from federal income tax while preserving
capital and maintaining liquidity. The Trust seeks to attain its objective
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, some of which may be secured by the full faith and credit of the
U.S. Government. All obligations purchased by the Trust will mature, or be
deemed to mature, in 397 days (13 months) or less or will have interest rates
adjusted in accordance with established indexes (e.g. the prime rate) not less
frequently than semi-annually. There can be no assurance that the Trust's
objective will be achieved.

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

The Trust has entered into an Agreement and Plan of Reorganization and
Liquidation, dated as of December 1, 1995 (the "Plan"), with The Cardinal Group,
an Ohio business trust (the "Group"). Pursuant to the Plan, Cardinal Tax Exempt
Money Market Fund, a series of the Group (the "Acquiring Fund"), would acquire
all of the assets of the Trust in exchange for the assumption of all of the
Trust's liabilities and a number of full and fractional shares of the Acquiring
Fund having an aggregate net asset value equal to the Trust's net assets (the
"Reorganization"). The Trust would then be liquidated, and the shares of the
Acquiring Fund would be distributed to Trust shareholders.
 
The Reorganization is subject to certain regulatory approvals and to approval by
the shareholders of the Trust at the Annual Shareholders Meeting currently
expected to be held in March, 1996. If the shareholders approve the
Reorganization, it is expected that the Reorganization would be effected on or
about March 31, 1996; however, the Reorganization may be effected on such
earlier or later date as the Group and the Trust may determine. There can be no
assurance that the Reorganization will take place when or as currently proposed.

<TABLE>
<S>                            <C>
TAX ADVANTAGES................. The Trust seeks to invest in securities which are free of
                                federal income tax, and in turn, pass through to the
                                investor tax free income. State and local taxes have not
                                been considered. (See page 7.)

HIGH CURRENT YIELDS............ The Trust seeks the maximum yield available through
                                investment in securities which earn attractive rates of
                                return free of federal income tax. (See page 7.)

MONTHLY DISTRIBUTIONS.......... Monthly distributions are automatically reinvested in
                                additional shares of the Trust without charge or may be
                                received in cash. (See pages 4 and 12.)

INSTANT LIQUIDITY.............. Through the free check writing privilege or telephone
                                transfer of funds, all or part of an investor's shares may
                                be redeemed on any business day at the net asset value
                                without charge. (See pages 13 and 14.)

LOW INITIAL INVESTMENT......... An investor can acquire shares of a high quality portfolio
                                of tax exempt securities with a smaller investment than
                                would be needed to purchase a similar portfolio directly.
                                (See page 10.)

PROFESSIONAL MANAGERS.......... The Trust's portfolio is fully managed by professional
                                portfolio managers. (See page 16.)

FLEXIBILITY.................... You may switch once each calendar quarter from one mutual
                                fund to another within the Cardinal Group of Funds as your
                                personal circumstances or market conditions dictate. Under
                                certain circumstances, however, a sales charge may be im-
                                posed on exchanges for shares of The Cardinal Fund Inc.,
                                Cardinal Government Obligations Fund, Cardinal Balanced
                                Fund and Cardinal Aggressive Growth Fund. (See page 17.)

MAXIMUM YIELD.................. As there is no sales charge to reduce the yield, investors
                                receive the maximum yield on their investment. Service
                                fees and charges have not been considered. (See pages 4
                                and 10.)

ACH PROCESSING................. Investors may use Automated Clearing House ("ACH")
                                processing for subsequent purchases of shares,
                                redemptions, and/or distributions paid. (See page 17.)

                                use its best efforts, under normal circumstances, to
                                maintain a constant net asset value of $1.00 per share.
                                There can be no assurance that it will be able to maintain
                                such a net asset value. There is no sales charge. (See
                                pages 10 and 15.)

                                page 7.)

                                including, but not limited to, bond anticipation notes,

                                Management Corp. also acts as investment adviser for
                                Cardinal Government Securities Trust, Cardinal Government
                                Obligations Fund, Cardinal Balanced Fund and Cardinal
                                Aggressive Growth Fund. (See page 16.)

                                redemption. The Trust may require a redemption of Shares
                                if the value of the account is less than $500. (See pages
                                12 and 13.)

From time to time the Trust may advertise its "yield" or "annualized yield," its
"effective yield," 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 the Trust
refers to the income generated by an investment in the Trust 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 Trust
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-equivalent yield" demonstrates the taxable yield
necessary to produce an after-tax yield equivalent to that of the Trust. The
"tax-equivalent effective yield" is calculated similarly to the "tax-equivalent
yield" but, when annualized, the income earned by an investment in the Trust 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 the Trust 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. and Standard &
Poor's Corporation and to data prepared by Lipper Analytical Services, Inc. and
CDA Investment Technologies, 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 Trust that appears in a

WHAT IS THE TRUST?
- - --------------------------------------------------------------------------------
 
The Trust is a diversified open-end management investment company established
under Ohio law by a Declaration of Trust dated January 13, 1983. The Declaration
of Trust permits the Trustees to issue an unlimited number of full and
fractional shares of beneficial interest, all of one class, with par value of
$.10 per share, and authorizes the Trustees to issue separate series of shares
differing only in certain specified respects. The Trustees have not currently
authorized separate series of shares. Each Share offered hereunder represents an
equal pro rata interest in the Trust's common portfolio. Upon liquidation,
shareholders are entitled to share pro rata in the net assets of the Trust
available for distribution to shareholders. Shares are freely transferable, have
no preemptive or conversion rights and are redeemable as set forth herein under
"HOW MAY I REDEEM MY SHARES?" Shares issued pursuant to the terms of the
Declaration of Trust are fully paid and nonassessable. Any additional series of
shares must be issued in compliance with the Investment Company Act of 1940, as
amended, and must not constitute a security that is senior to the Shares offered
pursuant to this Prospectus.

<PAGE>   167
 
- - --------------------------------------------------------------------------------
WHAT ARE THE INVESTMENT OBJECTIVE AND POLICIES OF THE TRUST?
- - --------------------------------------------------------------------------------
 
The investment objective of the Trust is to maximize current income exempt from
federal income tax while preserving capital and maintaining liquidity. The
investment objective with respect to the Trust is a fundamental policy and as
such may not be changed without a vote of the holders of a majority of the
outstanding Shares of the Trust.
 
As a money market fund, the Trust invests exclusively in United States
dollar-denominated instruments which the Trustees of the Trust and the Trust's
investment 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 ("NRSRO") (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. All
securities or instruments in which the Trust invests have, or are deemed to
have, remaining maturities of 397 calendar days (thirteen months) or less. The
dollar-weighted average maturity of the obligations in the Trust will not exceed
90 days.
 
As a matter of policy, under normal market conditions, the Trust 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 objective, the Trust expects to invest in the following types of
securities.
 
The Trust may invest in bond anticipation notes, construction loan notes,
project notes, revenue anticipation notes and tax anticipation notes, as well as
municipal bonds and participation interests therein, including industrial
development revenue bonds and pollution control revenue bonds (collectively,
"Municipal Securities"). The Trust may also acquire "stand-by commitments" with
respect to Municipal Securities held in its portfolio. Under a "stand-by
commitment" a dealer agrees to purchase, at the Trust's option, specified
Municipal Securities at a specified price which ordinarily is substantially the
same as the value of the underlying Municipal Security.
 
Specific types of Municipal Securities which the Trust may purchase include 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 MIG-1 or MIG-2, or
subsequent equivalents by Moody's Investors Service, Inc. ("Moody's") or (3) if
the notes are not rated, are, as determined by Cardinal Management Corp., the
Trust's adviser (the "Adviser") in accordance with guidelines established by the
Board of Trustees, of a quality equivalent to MIG-1 or MIG-2. The Trust may also
invest in municipal bonds and participation interests therein, including
industrial development revenue bonds and pollution control revenue bonds, which
(1) are rated Aaa or Aa by Moody's, (2) are rated AAA or AA by Standard & Poor's
Corporation ("S&P") or (3) if not rated, have, in the opinion of the Adviser
determined in accordance with guidelines established by the Board of Trustees,
essentially the same characteristics and quality as bonds having the above
ratings. In addition, the Trust may purchase other types of tax-exempt Municipal
Securities such as short-term discount notes. These investments must (1) be
rated Prime-1 or Prime-2 by Moody's or (2) if not rated, possess equivalent
characteristics and quality in the opinion of the Adviser determined in
accordance with guidelines established by the Board of Trustees.
As of December 31, 1995, the Trust was 100% invested in Municipal Securities
rated AAA or AA (bonds), SP-1 (notes) or A-1 (variable rate demand obligations)
by S&P, or Aaa or Aa (bonds), MIG-1 (notes) or VMIG-I (variable rate demand
obligations) by Moody's. 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.
The Trust has invested 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 Trust
is invested in such securities, the degree of
 
                                                                             7
<PAGE>   168
 
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 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 Trust, 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 Trust 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 Trust can be maintained at $1.00 per
share while the highest possible yield can be returned to investors. To the
extent the Trust'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 Trust'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 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 Trust invests may be
supported by bank letters of credit or comparable guarantees of financial
institutions. To the extent that 25% or more of the Trust's assets are invested
in variable rate demand Municipal Securities supported by such letters of credit
or guarantees, the Trust may be deemed to be concentrated in the banking
industry. (See "Certain Factors.")
 
In addition, the Trust may enter into commitments to purchase Municipal
Securities on a "when-issued" basis. Pursuant to such commitments, delivery and
payment for the Municipal Securities normally takes place at a date after the
commitment to purchase although the payment obligation and the coupon rate have
been established before the time the Trust enters into the commitment. The
settlement date usually occurs within one week of the purchase of notes and
within one month of the purchase of bonds. At the time the Trust makes such a
commitment to purchase a Municipal Security, it will record the transaction and
reflect the value of the obligation in determining its net asset value. No
interest accrues to the Trust until delivery and payment take place. The
Custodian will maintain on a daily basis a separate Trust account consisting of
cash or liquid debt securities with a value at least equal to the amount of the
Trust's commitments to purchase when-issued obligations.
 
Municipal Securities purchased on a when-issued basis or held in the Trust's
portfolio are subject to changes in market value based not only upon the
public's perception of the credit worthiness of the issuer but also upon changes
in the level of interest rates. Such changes in value will generally result in
both changing in value in the same way, i.e. both appreciating when interest
rates decline and depreciating when interest rates rise. Therefore, if to
achieve higher interest income the Trust remains substantially fully invested at
the same time that it has purchased securities on a when-issued basis, there
will be a greater possibility that the market value of the Trust's assets will
vary from $1.00 per share. (See "HOW IS NET ASSET VALUE CALCULATED?") In
addition, the Trust may, when it purchases Municipal Securities on a when-issued
basis, obtain on the settlement date, Municipal Securities yielding higher or
lower rates of interest than are otherwise available. However, the Trust does
not believe that under normal circumstances its net asset value or income will
be affected by its purchase of Municipal Securities on a when-issued basis.
 
TAXABLE MONEY MARKET SECURITIES
 
Under normal operating circumstances, Trust assets will be managed with a view
towards producing only income that is exempt from federal income taxation.
However, the Trust may invest up to 20% of its assets in "temporary
investments," that is, money market instruments consisting of marketable
obligations issued
 
8
<PAGE>   169
 
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 ("FDIC"), bankers' acceptances, high-grade
commercial paper guaranteed or issued by domestic corporations and instruments
(including repurchase agreements) secured by such obligations.
 
A repurchase agreement is an instrument under which the purchaser acquires
ownership of the obligation but the seller agrees, at the time of sale, to
repurchase the obligation at a mutually agreed upon time and price. The resale
price reflects an agreed upon market rate of interest which is unrelated to the
coupon rate or maturity of the purchased security. Repurchase agreements are
considered under the Investment Company Act of 1940, as amended (the "1940 Act")
to be loans made by the Trust. The Trust will only enter into a repurchase
agreement where (i) the underlying securities are of the type which the Trust's
investment guidelines 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 custodian or a bank acting as agent.
The Adviser will be responsible for continuously monitoring such requirements.
In the event of a bankruptcy or other default of a seller of a repurchase
agreement, the Trust could experience both delays in liquidating the underlying
securities and losses, including: (a) possible decline in the value of the
underlying security during the period while the Trust 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.
 
The Trust will not enter into repurchase agreements in violation of the 1940
Act. The Trust 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.
 
LOANS AND LOAN PARTICIPATIONS
 
The Trust may, for temporary or emergency non-investment purposes, such as to
accommodate abnormally heavy redemption requests, borrow money in an amount not
exceeding 5% of the value of the Trust's total assets at the time of borrowing.
The Trust may also acquire participations in privately negotiated loans to
municipal borrowers, provided that the interest received by the Trust is exempt,
in the opinion of bond counsel to the municipal borrower, from federal income
tax. Loan participations are loans subject to the Trust's investment
restrictions applicable to these activities. (See "INVESTMENT LIMITATIONS" in
the Statement of Additional Information.)
 
INVESTMENT COMPANY SECURITIES
 
The Trust 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 Trust intends to invest in money market mutual funds for
purposes of short-term cash management. The Trust'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 Trust's investments in other investment companies, see
"INVESTMENT OBJECTIVES AND POLICIES -- Additional Information on Portfolio
Instruments -- Securities of Other Investment Companies" in the Trust's
Statement of Additional Information.
 
CERTAIN FACTORS
 
Naturally, there can be no assurance that the Trust will achieve its investment
objective or be able continuously to maintain a net asset value per share of
$1.00. The characteristics of short-term Municipal Securities are such that the
price stability and liquidity of the Trust may not be equal to that of a money
market fund which exclusively invests in short-term taxable money market
securities. While the Adviser believes that the purchase of variable rate demand
Municipal Securities will facilitate maintaining a $1.00 per share net asset
value, the Trust is still expected to have a significantly longer average
maturity than a
 
                                                                              9
<PAGE>   170
 
general purpose taxable money market fund with the result that the pricing of
its portfolio will tend to be more subject to short-term interest rate
fluctuations.
 
In addition, the Trust expects that substantially all the demand rights of the
Trust with respect to variable rate demand Municipal Securities will be
supported by letters of credit of major commercial banks. Trust 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 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.

HOW DO I PURCHASE SHARES OF THE TRUST?
- - --------------------------------------------------------------------------------
 
GENERAL
 
Shares of the Trust 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,
the Trust's 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 is $1,000 and
subsequent investments must be in amounts of at least $100. The Trust 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. Shares of the Trust 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 Trust or by The Ohio Company.
 
Each new investor must complete an Application Form and send it to the Trust at
the indicated address either prior to or concurrently with the transmittal of
funds by wire or mail.
 
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. The Trust 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 ("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 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 Trust reserves the right to reject
any order to purchase its Shares. Certificates representing Shares of the Trust
will not be issued. All Shares purchased are confirmed to the investor and
credited to the investor's account on the Trust's books maintained by Cardinal
Management Corp. The investor will have the same rights and ownership with
respect to such Shares as if certificates had been 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 Trust. 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 the Trust 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 Trust. Compensation will
include payment for travel expenses,

10
<PAGE>   171

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 Trust'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 Trust or its shareholders.
 
PURCHASE BY FEDERAL FUNDS WIRE
 
Investments in Shares of the Trust 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 Trust at (800) 282-9446, toll
free, prior to wire transfer of its investment to advise the Trust of the
investment and, if a new investor, to obtain an account number. If an investor
does not telephone the Trust 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: Cardinal Tax Exempt Money Trust
                   [Include Trust Account Number and Name of Account Holder]

Funds transmitted by wire will be invested in Shares of the Trust at the net
asset value next computed after receipt thereof as follows. Investment will
occur on the same day as the transfer of funds so long as federal funds are
received by The Ohio Company prior to 12:00 noon Eastern Time on any Business
Day. Federal funds received by The Ohio Company after 12:00 noon Eastern Time
will not be invested until the next Business Day. Dividends will accrue on the
day a purchase is effected only if federal funds are received by The Ohio
Company by 12:00 noon Eastern Time. A bank may charge for its services in
effecting wire transfers of funds.
 
Subsequent purchases of Shares of the Trust may be made by ACH processing as
described under "WHAT OTHER SHAREHOLDER PROGRAMS ARE PROVIDED? -- ACH
Processing" below.
 
PURCHASE BY MAIL
 
Investment in Shares of the Trust may be made by mail by sending a check or
other negotiable bank draft payable to the order of "Cardinal Tax Exempt Money
Trust" together with, in the case of an initial purchase, an Application Form
to:
 
                            Cardinal Tax Exempt Money Trust
                            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 Trust
within one Business Day following receipt by The Ohio Company. Checks drawn on
non-member banks may take considerably longer. Cardinal Management Corp. or the
Trust will attempt to notify the investor upon receipt of the latter type of
check as to the possible delay and to arrange for a better means of transmittal
of funds. THE TRUST STRONGLY RECOMMENDS THAT INVESTORS OF SUBSTANTIAL AMOUNTS
USE FEDERAL FUNDS TO PURCHASE SHARES.
 
                                                                             11
<PAGE>   172
 
AUTOMATIC INVESTMENT PLAN
 
The Trust 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 the Trust on the
periodic basis you select. Confirmation of your purchase of Trust Shares will be
provided by the Trust. The debit to 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?
- - --------------------------------------------------------------------------------
 
The Trust's net income is declared as a dividend and accrued on each Business
Day, immediately prior to the determination of the Trust's net asset value at
4:00 p.m. Eastern Time. Net interest income (from the time of the immediately
preceding declaration) consists of interest accrued on the portfolio of the
Trust (including accrued discount earned and premium amortized), plus realized
net short-term capital gains (losses) due to portfolio transactions (if any),
less the accrued expenses of the Trust applicable to that
dividend period. While the Trust does not expect to realize any long-term
capital gains due to its policy of investing in securities maturing in 13 months
or less, any net long-term gain is expected to be distributed in January of the
fiscal year following realization. Long-term capital gains, if any, will be paid
in additional Shares of the Trust unless the shareholder elects to receive cash.
 
All dividends of net income are credited to each shareholder's account daily and
automatically reinvested in additional Shares of the Trust at the net asset
value on the last Business Day of each month. Shareholders, however, may elect
to receive monthly the 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 Cardinal Management Corp. in writing. 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 elect to receive cash distributions by using ACH processing as
described under "WHAT OTHER SHAREHOLDER PROGRAMS ARE PROVIDED? -- ACH
Processing" below.
 
Should the Trust incur or anticipate any extraordinary expense or 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 the Trust's net
asset value per share were reduced, or expected to be reduced, below $1.00, the
Trustees might suspend further dividend accruals until the net asset value
returned to $1.00. Thus, extraordinary expenses or losses or depreciation may
result in no dividends being accrued for the period during which an investor
holds Shares as well as a redemption price lower than the purchase price for
such Shares.
 
- - --------------------------------------------------------------------------------
HOW MAY I REDEEM MY SHARES?
- - --------------------------------------------------------------------------------
 
Investors may redeem Shares of the Trust on any Business Day at the net asset
value next determined following receipt by the Trust's transfer agent, Cardinal
Management Corp., 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 Cardinal Management Corp. 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 Cardinal Management Corp. in proper
form before (1) 4:00 p.m. Eastern Time for shareholders who are customers of The
Ohio Company and who have submitted
 
12
<PAGE>   173
 
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 Trust 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 Trust). The purchase of Trust
Shares by wire transfer of federal funds would avoid any such delay.
 
The Trust 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 Trust 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 to a
net asset value below $500. A shareholder will be notified in writing that the
value of the account is less than $500 and allowed not less than 30 days to
increase the account 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 elect to redeem Shares of the Trust by submitting a written
request therefor to Cardinal Management Corp., the Trust's transfer agent at 215
East Capital Street, Columbus, Ohio 43215. Cardinal Management Corp. 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. Cardinal Management Corp. 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 elect to redeem Shares of the Trust by calling the Trust 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 or
another address.

Neither the Trust 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 Trust's telephone redemption procedures, acting upon
instructions reasonably believed to be genuine. The Trust will employ procedures
designed to provide reasonable assurances that instructions by telephone are
genuine; if these procedures are not followed, the Trust 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
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.
 
                                                                            13
<PAGE>   174
 
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 Trust 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 Trust 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 Trust's 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 Trust 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 Trust's Systematic Withdrawal Plan.
Please contact The Ohio Company for the appropriate form.
 
CHECK-WRITING REDEMPTION PROCEDURE
 
Cardinal Management Corp., as Transfer Agent for the Trust, will provide any
shareholder who so requests with a supply of checks, imprinted with the
shareholder's name, which may be drawn against the Trust's account maintained by
The Fifth Third Bank (the "Bank"), for redemption of Trust Shares. These checks
may be made payable to the order of any person in any amount not less than $250.
To participate in this procedure, an investor must complete the Check-Writing
Redemption Form available from Cardinal Management Corp. When a check is
presented to the Bank for payment, Cardinal Management Corp. (as your agent)
will cause the Trust 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 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 Trust 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.

- - --------------------------------------------------------------------------------
HOW IS NET ASSET VALUE CALCULATED?
- - --------------------------------------------------------------------------------
 
The net asset value per share of the Trust is currently determined as of 4:00
p.m. Eastern Time on each Business Day (and at such other time or times as the
Board of Trustees may determine). The net asset value per share is computed by
dividing the total value of the assets of the Trust, less its liabilities, by
the total number of Shares outstanding.
 
The Board of Trustees has adopted a policy requiring the Trust to use its best
efforts, under normal circumstances, to maintain a constant net asset value of
$1.00 per Share. The Trust 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. The Trust will normally
include any accrued discount or premium in its daily dividend and will thereby
keep constant the value of the Trust'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.
 
- - --------------------------------------------------------------------------------
DOES THE TRUST PAY FEDERAL INCOME TAX?
- - --------------------------------------------------------------------------------
 
The Trust intends to qualify as a "regulated investment company" under the Code
for so long as such qualification is in the best interest of the Trust'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 and
90% of its exempt interest income. The Trust contemplates declaring as dividends
100% of the Trust's investment company taxable income (before deduction of
dividends paid) and 100% of its exempt interest income.
 
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 Trust would be
subject to a nondeductible excise tax equal to 4% of the deficiency.
 
- - --------------------------------------------------------------------------------
WHAT ABOUT MY TAXES?
- - --------------------------------------------------------------------------------
 
FEDERAL TAXES
 
The Trust 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
Trust 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 Trust will also be treated as tax preference items in
computing the alternative minimum tax to the extent, if any, that distributions
by the Trust are attributable to interest earned by the Trust 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 preference alternative minimum taxable 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 Trust. Dividends, if any, derived from
 
                                                                             15
<PAGE>   176
 
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 Trust anticipates that substantially all of its dividends will be
excluded from gross income for federal income tax purposes and will notify each
shareholder annually of the tax status of all distributions.
 
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 Trust 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 Securities held by the Trust during the preceding
year.
 
The foregoing is intended only as a brief summary of some of the important tax
considerations generally affecting the Trust and its shareholders. Potential
investors in the Trust 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.

WHO MANAGES MY INVESTMENT IN THE TRUST?

responsibility for the management of the Trust is vested in its Board of
Trustees which, among other things, is empowered by the Trust's Declaration Of
Trust to elect officers of the Trust and contract with and provide for the
compensation of agents, consultants and other professionals to assist and advise
in such management.
 
INVESTMENT ADVISER AND MANAGER

Cardinal Management Corp. (the "Adviser"), located at 155 East Broad Street,
Columbus, Ohio 43215, is a wholly-owned subsidiary of The Ohio Company and is
also the investment adviser to Cardinal Government Securities Trust ("CGST"),
Cardinal Government Obligations Fund ("CGOF"), Cardinal Balanced Fund ("CBF")
and Cardinal Aggressive Growth Fund ("CAGF"). The Adviser also acts as dividend
and transfer agent for The Cardinal Fund Inc., another open-end diversified
management investment company ("CFI"), CGST, CGOF, CBF, CAGF and the Trust. The
Ohio Company is a member of the New York and Chicago Stock Exchanges, other
regional exchanges and the National Association of Securities Dealers, Inc. In
addition to acting as the principal underwriter for the Trust, CGST, CGOF, CBF
and CAGF, The Ohio Company acts as investment adviser and principal underwriter
for CFI, and as the sponsor of various series of separate unit investment
trusts.
 
Pursuant to the Investment Advisory Contract, the Adviser manages the investment
and reinvestment of the assets of the Trust in accordance with the Trust's
investment objective, policies and restrictions, subject to the general

been a Vice President of The Ohio Company and the Adviser since 1990 and has
more than 25 years of investment management experience.
 
As compensation for its services to the Trust, the Adviser receives monthly from
the Trust a management fee at the annual rate of .5% of the average daily net
assets of the Trust. The Adviser may, however, periodically waive all or a
portion of its advisory fee with respect to the Trust to increase the net income
of the Trust available for distribution as dividends. The waiver of such fee
will cause the yield of the Trust to be higher than it would otherwise be in the
absence of such a waiver.

WHAT OTHER SHAREHOLDER PROGRAMS ARE PROVIDED?
- - --------------------------------------------------------------------------------
 
ACH PROCESSING
 
The Trust now offers ACH privileges. Investors may use ACH processing to make
subsequent purchases, redeem Shares and/or electronically transfer distributions
paid on Trust 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
 
Investors 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 the Trust for shares of:
 
       Cardinal Government Securities Trust,
       a short-term U.S. Government securities fund (without payment of any 
       sales charge);
 
       Cardinal Aggressive Growth Fund,
       an equity fund seeking appreciation of capital (upon the payment of the
       applicable sales charge);
 
                                                                            17
<PAGE>   178
 
        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);
 
        The Cardinal Fund Inc.,
        an equity fund (upon payment of applicable sales charge); or
 
        Cardinal Government Obligations Fund,
        a U.S. Government bond fund (upon payment of applicable sales charge).
 
Notwithstanding the foregoing and subject to the limitations contained in the
following paragraph, exchanges of Trust Shares for shares of CFI, CGOF, CBF or
CAGF (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
shares of that Cardinal Load Fund. If, however, the Shares of Trust 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 may be exercised only once in each calendar
quarter and 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. Cardinal Management Corp., as 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 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
the Trust by telephone. Neither the Trust nor any of its service providers will
be liable of 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 Trust may, at any time, modify or terminate the foregoing exchange
privilege. The Trust, however, will give shareholders of the Trust 60 days
advance written notice of any such modification or termination.
 
- - --------------------------------------------------------------------------------
WHAT ARE MY RIGHTS AS A SHAREHOLDER?
- - --------------------------------------------------------------------------------
 
Each Share is entitled to one vote (and fractional Shares to proportionate
fractional votes) in the election of Trustees and on other matters submitted to
the vote of shareholders. Voting rights are not cumulative, so that the holders
of more than 50% of the Shares voting in the election of Trustees have the power
to elect all of the Trustees of the Trust. Whenever the approval of a majority
of the outstanding Shares of the Trust is required in connection with
shareholder approvals of the Investment Advisory Contract, the Distribution
Contract or changes in the investment objective and policies or the investment
restrictions of the Trust, a "majority" shall mean the vote of (i) 67% or more
of the Shares of the Trust present at a meeting, if the holders of more than 50%
of the outstanding Shares are present in person or by proxy, or (ii) more than
50% of the outstanding Shares of the Trust, whichever is less.
 
- - --------------------------------------------------------------------------------
WHAT SHAREHOLDER REPORTS WILL I RECEIVE?
- - --------------------------------------------------------------------------------
 
An account summary will be furnished to each shareholder monthly and will
include information as to all purchases, redemptions and income dividends paid
with respect to the preceding month. Financial statements of the Trust will be
furnished to shareholders semiannually.
 
Holders of Shares should direct all inquiries concerning such matters to
Cardinal Management Corp., 155 East Broad Street, Columbus, Ohio 43215.

STATEMENT OF ADDITIONAL INFORMATION


                        CARDINAL TAX EXEMPT MONEY TRUST


         Cardinal Tax Exempt Money Trust (the "Trust") is a no-load,
diversified, open-end management investment company with an investment
objective of maximizing current income exempt from federal income tax while
preserving capital and maintaining liquidity.  The Trust seeks to attain its
objective 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, some of which may be secured by the full
faith and credit of the U.S. Government.  All obligations purchased by the
Trust will mature, or be deemed to mature, in 397 days (13 months) or less or
will have interest rates adjusted in accordance with established indexes (e.g.
the prime rate) not less frequently than semi-annually.  There can be no
assurance that the Trust's objective will be achieved.

         The Trust is designed for institutions and individuals who desire
current income exempt from federal income tax that reflects prevailing interest
rates for short-term tax-exempt investments together with a high degree of
liquidity.

                      STATEMENT OF ADDITIONAL INFORMATION


                        CARDINAL TAX EXEMPT MONEY TRUST

         Cardinal Tax Exempt Money Trust (the "Trust") is an open-end
management investment company.  Much of the information contained in this
Statement of Additional Information expands upon subjects discussed in the
Prospectus of the Trust.  Capitalized terms not defined herein are defined in
the Prospectus.  No investment in Shares of the Trust should be made without
first reading the Prospectus of the Trust.


                       INVESTMENT OBJECTIVE AND POLICIES

General
- - -------

         The Trust invests primarily in high grade short-term Municipal
Securities which at the time of investment have, or are deemed to have,
remaining maturities of 397 days (13 months) or less or which have variable
rates, demand features and quality characteristics which permit the Trust to
treat them as maturing in 397 days or less.  The dollar weighted average
portfolio will have a maturity of less than 90 days.  See "ADDITIONAL PURCHASE
AND REDEMPTION INFORMATION -- Determination of Net Asset Value."

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

         GENERAL.  The term "Municipal Securities", as used in this Statement
of Additional Information means debt obligations issued by or on behalf of any
state, territory or possession of the United States or the District of Columbia
or their political subdivisions, agencies or instrumentalities, and
participation interests therein, the interest on which is, in the opinion of
counsel for the issuer, wholly exempt from federal income taxation.  See
"Municipal Securities" below.

         Specific types of Municipal Securities which the Trust may purchase
include 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 MIG
1 or MIG 2, or subsequent equivalents by Moody's Investors Service, Inc.
("Moody's") or (3) if the notes are not rated, are, as determined by Cardinal
Management Corp., the Trust's adviser (the "Adviser") in accordance with
guidelines established by the Board of Trustees, of a quality equivalent to MIG
1 or MIG 2.

         The Trust may also invest in municipal bonds and participation
interests therein, including industrial development revenue bonds and pollution
control revenue bonds, which are (1) rated Aaa or Aa by Moody's, (2) rated AAA
or AA by Standard & Poor's Corporation





                                      B-1
<PAGE>   184
("S&P") or (3) if not rated, have, in the opinion of the Adviser determined in
accordance with the guidelines established by the Board of Trustees,
essentially the same characteristics and quality as bonds having the above
ratings.

         In addition, the Trust may purchase other types of tax-exempt
Municipal Securities such as short-term discount notes.  These investments must
be (1) rated Prime-1 or Prime-2 by Moody's or (2) if not rated, possess
equivalent characteristics and quality in the opinion of the Adviser determined
in accordance with guidelines established by the Board of Trustees.

         The Appendix contains a description of the ratings set forth above.

         The Trust may acquire participations in privately negotiated loans to
municipal borrowers, provided that the Trust has received an opinion from bond
counsel to the municipal borrower that the interest received by the Trust is
exempt from federal income tax and the loans are otherwise in accordance with
the Trust's investment objective and restrictions.

         The Trust 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.  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.  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 "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.





                                      B-2
<PAGE>   185
         The Municipal Securities described herein represent those which the
Trust 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 objective, the
Trust 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, the Trust may not purchase any municipal bonds or notes having
characteristics or terms that are inconsistent with the investment objective or
investment policies of the Trust.

         Subsequent to the Trust'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 Investment Company Act of 1940 (the "1940 Act"), and receives a rating
by any nationally recognized statistical rating organization 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.

         MUNICIPAL SECURITIES.  Municipal Securities which may be purchased by
the Trust 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 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





                                      B-3
<PAGE>   186
         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
the Trust to treat them as having maturities of less than 397 days.  See
"Determination of Net Asset Value" herein and "HOW IS NET ASSET VALUE
CALCULATED?" in the Prospectus.

                 1.  GENERAL OBLIGATION BONDS.  General obligation bonds
         are issued by states, counties, regional districts, cities, 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.





                                      B-4
<PAGE>   187
                 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
the Trust's portfolio.  If any such legislation has a materially adverse effect
on the Trust's ability to achieve its investment objective, the Trust will
re-evaluate its investment objective and submit to its shareholders for
approval necessary changes in the objective and policies of the Trust.

         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 variable rate demand Municipal Securities in which the Trust may
invest are payable on demand on not more than seven





                                      B-5
<PAGE>   188
calendar days' notice.  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 the Trust are subject to the
quality characteristics for Municipal Securities described above and in the
Appendix to this Statement of Additional Information.  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 the Trust no longer meets the quality standards of the Trust, unless, of
course, the security can be sold for a greater amount in the market.

         The principal and accrued interest payable to the Trust 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 the Trust in Municipal
Securities, except in cases where the security itself meets the credit criteria
of the Trust without such letter of credit or comparable guarantee.  Thus,
although a variable rate demand security may be unrated, the Trust 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 the Trust may purchase
include participation interests in variable rate securities.  Such
participation interests will have, as part of the participation agreement
between the Trust and the selling financial institution, a demand feature which
permits the Trust to demand payment from the seller of the principal amount of
the Trust'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 the Trust has a participation interest over
the negotiated yield at which the participation interest was purchased by the
Trust.  Accordingly, the Trust will purchase such participation interests only
when the yield to the Trust, 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.

         TAXABLE MONEY MARKET SECURITIES.  The Trust may invest up to 20% of
its assets in taxable money market instruments when the





                                      B-6
<PAGE>   189
Adviser deems such investments to be in the best interests of shareholders. 
However, under normal circumstances, the Trust will be managed with a view
towards producing only income that is exempt from federal income taxes. 
Permissible taxable investments are as follows:

                 1.  U.S. GOVERNMENT OBLIGATIONS.  Obligations issued by the
         U.S. Government include bills, notes and bonds of the U.S.  Treasury,
         which differ only in their interest rates, maturities and times of
         issuance:  Treasury bills have a maturity of one year or less,
         Treasury notes have maturities of one to ten years and Treasury bonds
         generally have maturities of greater than ten years.  Obligations
         issued by agencies or instrumentalities of the U.S. Government
         include, among others, securities issued by 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.
         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 Trust will invest in such securities only when it is
         satisfied that the credit risk with respect to the issuer is minimal.

                 2.  OBLIGATIONS OF BANKS AND SAVINGS AND LOANS.  Investments
         in obligations of banks and savings and loans are limited to (1)
         certificates of deposit issued by domestic banks with assets in excess
         of five hundred million dollars, (2) certificates of deposit or other
         deposit obligations of savings and loans with assets in excess of five
         hundred million dollars, and (3) bankers' acceptances and letters of
         credit guaranteed by banks meeting the above criteria.  Bankers'
         acceptances and letters of credit are short-term credit instruments
         used to finance the import, export,





                                      B-7
<PAGE>   190
         transfer or storage of goods.  They are termed "accepted" when a bank
         guarantees their payment at maturity.  Obligations issued or
         guaranteed by Federal Deposit Insurance Corporation ("FDIC") member
         institutions are not necessarily guaranteed by the FDIC.  Deposit
         obligations of domestic banks and savings and loans are insured by the
         FDIC up to a maximum of $100,000, which limitation applies to all
         funds which the Trust may have on deposit at any one bank or savings
         and loan.  Bankers' acceptances and letters of credit are not so
         insured.

                 3.  COMMERCIAL PAPER.  Permissible commercial paper
         investments of the Trust consist of obligations rated Prime-1 or
         Prime-2, or A-1 or A-2, or their subsequent equivalents, by Moody's or
         S&P or unrated commercial paper issued by companies with an unsecured
         debt issue outstanding which is rated Aa or better by Moody's or AA or
         better by S&P.  These ratings are described in the Appendix.
         Commercial paper constitutes unsecured indebtedness of business or
         banking firms issued to finance their short-term financial needs.

         The Trust may also invest in repurchase agreements.  Repurchase
agreements are described in detail in the Prospectus.

         REVERSE REPURCHASE AGREEMENTS.  The Trust 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 the Trust's assets at the time of entering into the agreement.  The
Trust, however, has not entered into such agreements in the past and does not
intend to enter into such agreements in the foreseeable future.

         STAND-BY COMMITMENTS.  Pursuant to an exemptive order which the Trust
has received under the 1940 Act the Trust may also acquire "stand-by
commitments" with respect to Municipal Securities held in its portfolio.  Under
a "stand-by commitment," a dealer agrees to purchase, at the Trust's option,
specified Municipal Securities at a specified price.  "Stand-by commitments"
are the equivalent of a "put" option acquired by the Trust with respect to
particular Municipal Securities held in its portfolio.

         The amount payable to the Trust upon its exercise of a "stand-by
commitment" will normally be (i) the Trust's acquisition cost of the Municipal
Securities (excluding any accrued interest which the Trust paid on their
acquisition), less any amortized market premium or plus any amortized market or
original issue discount during the period the Trust owned the securities, plus
(ii) all interest accrued on the Municipal Securities since the last interest
payment date during the period such obligations are owned by the Trust.
"Stand-by commitments" which may be acquired by the Trust will be exercisable
by the Trust at any time prior to the underlying security's maturity.  Absent
unusual circumstances, the Trust will value the underlying Municipal Securities
on an amortized cost basis.  Accordingly, the amount payable by a dealer during
the time





                                      B-8
<PAGE>   191
a "stand-by commitment" is exercisable is substantially the same as the value
of the underlying Municipal Securities.  The Trust's right to exercise
"stand-by commitments" must be unconditional and unqualified.  A "stand-by
commitment" is not transferable by the Trust, although the Trust may sell the
underlying Municipal Securities to a third party at any time.

         The Trust expects that "stand-by commitments" will generally be
available without the payment of any direct or indirect consideration.
However, if necessary and advisable, the Trust may pay for "stand-by
commitments" either separately in cash or by paying a higher price for
Municipal Securities which are acquired subject to such a commitment (thus
reducing the yield to maturity otherwise available for the same securities).
The total amount paid in either manner for outstanding "stand-by commitments"
held in the Trust's portfolio may not exceed 1/2 of 1% of the value of the
Trust's total assets calculated immediately after each "stand-by commitment" is
acquired.

         The Trust intends to enter into "stand-by commitments" only with
dealers, banks and broker-dealers which in the opinion of the Adviser to the
Trust present minimum credit risks.  The Trust's reliance upon the credit of
these dealers, banks and broker-dealers is secured by the value of the
underlying Municipal Securities that are subject to the commitment.  However,
the failure of a party to honor a "stand-by commitment" to the Trust could have
an adverse impact on the liquidity of the Trust during periods of rising
interest rates.

         The Trust intends to acquire "stand-by commitments" solely to
facilitate portfolio liquidity and does not intend to exercise its rights
thereunder for trading purposes.  The acquisition of a "stand-by commitment"
will not affect the valuation or maturity of the underlying Municipal
Securities which will continue to be valued in accordance with the amortized
cost method.  "Stand-by commitments" acquired by the Trust will be valued at
zero in determining net asset value.  Where the Trust pays directly or
indirectly for a "stand-by commitment," its cost will be reflected as
unrealized depreciation for the period during which the commitment is held by
the Trust.  "Stand-by commitments" will not affect the average weighted
maturity of the Trust's portfolio.

         WHEN-ISSUED SECURITIES.  When payment is made for when-issued
securities, the Trust will meet its obligations from then-available cash flow,
sale of securities held in the separate account, sale of other securities or,
although it would normally not expect to do so, from sale of the when-issued
securities themselves (which may have a market value greater or less than the
Trust's obligation).  Sale of securities to meet such obligations would involve
a greater potential for the realization of capital gains, which could cause the
Trust to realize income not exempt from federal income taxation.  The Trust
intends to make commitments to purchase Municipal Securities with the intention
of actually acquiring such





                                      B-9
<PAGE>   192
obligations, but the Trust may sell the obligations before the settlement date
if it is advisable or necessary as a matter of investment strategy.

         SECURITIES OF OTHER INVESTMENT COMPANIES.  The Trust may invest in
securities issued by other investment companies.  The Trust 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 the
Trust.  As a shareholder of another investment company, the Trust would bear,
along with other shareholders, its pro rata portion of that company's expenses,
including advisory fees.  These expenses would be in addition to the advisory
and other expenses that the Trust bears directly in connection with its own
operations.  Investment companies in which the Trust may invest may also impose
a sales or distribution charge in connection with the purchase or redemption of
their shares and other types of commissions or charges.  Such charges will be
payable by the Trust and, therefore, will be borne directly by shareholders.

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

         In addition to the investment objective of the Trust, which may not be
changed without approval of shareholders owning a majority of the outstanding
Trust Shares (as defined under "WHAT IS THE TRUST?" in the Prospectus), the
Trust had adopted the following investment restrictions and limitations which
may not be changed without similar shareholder approval.  The Trust may 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 the Trust'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





                                      B-10
<PAGE>   193
         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 the Trust
         contemplates investing in are variable rate demand Municipal Securities
         supported by letters of credit or guarantees issued    by domestic
         branches of domestic banks);

                 (3)      borrow money or enter into reverse repurchase
         agreements except for temporary or emergency non-investment purposes,
         such as to accommodate abnormally heavy redemption requests, and then
         only in an amount not exceeding 5% of the value of the Trust's total
         assets at the time of borrowing;

                 (4)      pledge, mortgage or hypothecate its assets, except
         that to secure borrowing permitted by (3) above, 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;

                 (5)      underwrite any securities issued by others;

                 (6)      purchase or sell real estate, although the Trust may
         invest in Municipal Securities or temporary investments secured by
         interests in real estate;

                 (7)      purchase or sell commodities, commodity contracts or
         oil and gas interests;

                 (8)      make loans, other than by entering into repurchase
         agreements and through the purchase of participation in privately
         negotiated loans and portions of publicly issued debt obligations that
         are in accordance with its investment objective and policies;
         provided, however, that the Trust 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;

                 (9)      sell securities short or purchase any securities on
         margin, except for such short term credits as are necessary for the
         clearance of portfolio transactions;

                 (10)    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;

                 (11)     purchase or retain securities of any issuer for the
         Trust's portfolio if those officers and Trustees of the Trust or
         officers and Directors of its Adviser, who individually beneficially
         own more than 1/2 of 1% of the outstanding





                                      B-11
<PAGE>   194
         securities of such issuer, together beneficially own more than 5% of
         such outstanding securities;

                 (12)     invest in companies for the purposes of exercising
         control or management of another company;

                 (13)     purchase from or sell to any of its officers or
         Trustees or the officers or Directors of the Adviser, portfolio
         securities of the Trust;

                 (14)     purchase securities subject to legal or contractual
         restrictions on the resale thereof ("restricted securities") if such
         purchase would cause more than 10% of the Trust's assets (including
         repurchase agreements maturing in more than seven days) to be invested
         in restricted securities and other securities that are not readily
         marketable;

                 (15)     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; or

                 (16) 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.

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

         The Trust has represented to the Ohio Division of Securities that it
will (1) not invest its assets in the securities of other investment companies,
except by purchase in the open market where no commission or profit to a
sponsor or dealer results from the purchase other than the customary broker's
commission, or except when the purchase is part of a plan of merger,
consolidation, reorganization, or acquisition; and (2) limit its investments to
15% of its total assets in securities of any issuer (a) which, together with
any predecessors, have a record of less than three years continuous operation
or (b) which are restricted as to disposition, including securities eligible
for resale under Rule 144A of the Securities Act of 1933.  The Trust intends to
comply with these representations for so long as its Shares are registered for
sale in the State of Ohio.

                                      B-12
<PAGE>   195
         If a percentage restriction or limitation is adhered to at the time of
investment, a later increase or decrease in percentage resulting from a change
in values or net assets will not be considered a violation thereof.

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

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

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


                            MANAGEMENT OF THE TRUST

         **For purposes of this Table, Fund Complex means one or more mutual
funds, including the Trust, which have a common investment adviser or
affiliated investment advisers or which hold themselves out to the public as
being related.


                      PRINCIPAL SHAREHOLDERS OF THE TRUST

         The following is the only person known to the Trust to be the
beneficial owner of more than 5% of the Trust's outstanding Shares as of
January 11, 1996: The Ohio Company, 155 East Broad Street, Columbus, Ohio 43215
- - - 6.28%.


                                  THE ADVISER

         The Trust has entered into an Investment Advisory Contract with
Cardinal Management Corp. (the "Adviser").  Pursuant to the Investment Advisory
Contract, the Adviser has agreed to provide investment advisory and management
services as described in the Prospectus.  As compensation for such services to
the Trust, the Adviser receives monthly from the Trust a management fee at the
annual rate of 1/2 of 1% of the average daily net assets of the Trust.  Such
fee accrues daily.  The Adviser performs and bears the cost of research,
statistical analysis and continuous supervision of the investment portfolio of
the Trust and furnishes office facilities and certain clerical and
administrative services to the Trust.  In addition, the Adviser provides
dividend, transfer agency and fund accounting services to the Trust.

         The aggregate amount of investment management fees earned by the
Adviser during the fiscal years ended September 30, 1995, 1994 and 1993, was
$344,000, $449,777 and $449,464, respectively.

         Pursuant to the Investment Advisory Contract, if the aggregate
expenses of the Trust (including fees pursuant to the Investment Advisory
Contract, but excluding taxes, interest, brokerage fees, commissions and
extraordinary expenses) for any fiscal year exceed 1% of average net assets,
the Adviser is to refund to the Trust, or otherwise bear, such excess.  The
Adviser was not obligated to refund or pay any expenses of the Trust for the
three fiscal years ended September 30, 1995.

         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 an officer of The Ohio Company.

         The Investment Advisory Contract was last approved by a majority of
both the trustees and those trustees who are not


                                      B-17
<PAGE>   200
"interested persons" (as defined in the 1940 Act) of either the Trust or the
Adviser of the Trust at a meeting held for such purposes on November 13, 1995,
and was last approved by the shareholders of the Trust on April 9, 1984.  The
Investment Advisory Contract will continue in force from year to year if
specifically approved at least annually by the Board of Trustees of the Trust
or by the vote of a majority of the outstanding Shares of the Trust.  In either
event, the Contract must also be approved by vote of a majority of the Trustees
who are not "interested persons" of any party to such Contract, cast in person
at a meeting called for such purpose.  The Contract may be terminated by either
party, at any time, without penalty, upon sixty days' written notice, and will
automatically terminate in the event of its assignment.  Termination will not
affect the right of the Adviser to receive payments on any unpaid balance of
the compensation earned prior to termination.

                             PORTFOLIO TRANSACTIONS

         Pursuant to the Investment Advisory Contract, the Adviser, subject to
the policies established by the Board of Trustees of the Trust and in
accordance with the Trust's investment restrictions and policies, is
responsible for the Trust's portfolio decisions and the placing of the Trust's
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 in the
over-the-counter market are generally principal transactions with dealers.
With respect to the over-the-counter market, the Trust, 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.

         In executing such transactions, the Adviser seeks to obtain the best
net results for the Trust 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, the Trust will not necessarily be paying the lowest
commission or spread available.  For the past three fiscal years, the Trust has
paid no brokerage commissions.

         The Adviser may consider provision of research, statistical and other
information to the Trust or the Adviser in the selection of qualified
broker-dealers who effect portfolio transactions for





                                      B-18
<PAGE>   201
the Trust so long as the Adviser's ability to obtain the best net results for
portfolio transactions of the Trust 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 the Trust.
Although this information is useful to the Trust and the Adviser, 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 Trust
under the Investment Advisory Contract.  The Trust 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.

         Investment decisions for the Trust are made independently from those
for any other investment company or account managed by the Adviser.  Any such
other investment company or account may also invest in the same securities as
the Trust.  When a purchase or sale of the same security is made at
substantially the same time on behalf of the Trust and another 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 Trust and such other investment company or
account.  In some instances, this investment procedure may adversely affect the
price paid or received by the Trust or the size of the position obtained by the
Trust.  To the extent permitted by law, the Adviser may aggregate the
securities to be sold or purchased for the Trust with those to be sold or
purchased 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 Trust, the Adviser will not inquire or take
into consideration whether an issuer of securities proposed for purchase or
sale by the Trust 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 Trust.

         The Trust did not, during the fiscal year ended September 30, 1995,
hold any securities of its regular brokers or dealers, as defined in Rule 10b-1
under the 1940 Act, or their parent companies.

                              ACCOUNTING SERVICES

         The Trust has entered into an Accounting Services Agreement with the
Adviser pursuant to which the Adviser has agreed to maintain and keep current
the books, accounts, records, journals and other records of original entry
relating to the business of the Trust and to calculate the Trust's net asset
value on a daily basis.  In consideration of such services, the Trust has
agreed to pay monthly to the Adviser a fee based on the average monthly net
asset value of the Trust.  For the last three fiscal years ended September 30,
1995, the Adviser received $17,235, $19,928 and $19,819, respectively, for its
services to the Trust pursuant to such Agreement.


                  TRANSFER AGENT AND DIVIDEND DISBURSING AGENT

         The Trust has entered into an Administration Agreement with the
Adviser pursuant to which the Adviser has agreed to act as the Trust's transfer
agent and dividend disbursing agent and to perform certain check redemption
services for the Trust.  In consideration of such services, the Trust has
agreed to pay the Adviser an annual fee paid monthly, equal to $21 per
shareholder account plus the Adviser's out-of-pocket expenses.  For the last
three fiscal years ended September 30, 1995, the Adviser received $62,542,
$75,550 and $75,017, respectively, for its services to the Trust pursuant to
such Agreement.

                                  DISTRIBUTOR

         The Ohio Company, with principal offices located at 155 East Broad
Street, Columbus, Ohio 43215, serves as the Trust's principal underwriter and,
in connection therewith, is available to receive purchase orders and redemption
requests relating to Shares of the Trust and to transmit such orders and
requests to the Trust's custodian.  The Ohio Company does not receive any
compensation from the Trust or charge any fees to investors for its services
rendered as principal underwriter of the Trust's Shares.
         The Distribution Contract was last approved by both the Trustees and
those Trustees who are not "interested persons" (as defined in the 1940 Act) of
either the Trust or The Ohio Company at a meeting held for such purpose on
November 13, 1995, and was last approved by the shareholders of the Trust on
April 9, 1984.  The Distribution Contract will continue in effect from year to
year if specifically approved at least annually by the Board of Trustees of the
Trust or by the vote of a majority of the outstanding Shares of the Trust.  In
either event, the Distribution Contract must also be approved by vote of a
majority of the Trustees who are not "interested persons" of any party to the
Distribution Contract, cast in person at a meeting called for such purpose.
The





                                      B-20
<PAGE>   203
Distribution Contract will automatically terminate in the event of its
assignment.


                                   CUSTODIAN

         The Fifth Third Bank (the "Bank"), 38 Fountain Square, Cincinnati,
Ohio 45263, has been selected to act as Custodian of the portfolio securities
and cash of the Trust.  The Bank has no part in determining the investment
policies of the Trust or in deciding which securities are to be purchased or
sold by the Trust.  The Trust may enter into repurchase agreements with the
Bank and may purchase or sell securities from or to the Bank.


                     LEGAL COUNSEL AND INDEPENDENT AUDITORS

         Certain legal matters as to the issuance of the Shares offered hereby
have been passed upon by Baker & Hostetler, 65 East State Street, Columbus,
Ohio 43215.  The Trust has selected KPMG Peat Marwick LLP, Two Nationwide
Plaza, Columbus, Ohio 43215, as independent auditors for the Trust.  The
financial statements of the Trust 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

         The Trust's Shares may be purchased at the public offering price and
are sold on a continuous basis through The Ohio Company, principal underwriter
of the Trust's Shares, at its address and number set forth on the cover page of
this Statement of Additional Information, and through other broker-dealers who
are members of the National Association of Securities Dealers, Inc. and have
sales agreements with The Ohio Company.

         The Trust 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 Securities and Exchange Commission, (b) the Exchange is closed for other
than customary weekend and holiday closings, (c) the Securities and Exchange
Commission has by order permitted such suspension, or (c) an emergency exists
as a result of which (i) disposal by the Trust of securities owned by it is not
reasonably practical or (ii) it is not reasonably practical for the Trust to
determine the fair value of its net assets.

         Use of the check-writing redemption procedure will be subject to the
rules and regulations of The Fifth Third Bank (the "Bank") governing checking
accounts.  Neither the Bank nor the Trust shall





                                      B-21
<PAGE>   204
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 Trust, 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 Trust values its portfolio securities 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 Trust's shareholders in the daily dividend, the
value of the Trust'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 the Trust's
securities, as determined by amortized cost, is higher or lower than the price
the Trust would receive if it sold the securities.  During such periods, the
yield on Shares of the Trust may differ somewhat from that obtained in a
similar fund with identical investments utilizing a method of 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 the Trust resulted in
a lower aggregate portfolio value on a particular day, a prospective investor
in the Trust 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 Trust would receive less investment income.  The converse
would apply in a period of rising interest rates.

         The valuation of the Trust's portfolio securities based upon their
amortized cost and the maintenance of the Trust's per share net asset value of
$1.00 is permitted based on the Trust's 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 Trust's net asset
value per share, as computed for the purpose of sales and redemptions, at
$1.00.  Such procedures include review of the Trust's portfolio holdings by the
Board of Trustees at such intervals as it may deem appropriate to determine
whether the Trust's 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





                                      B-22
<PAGE>   205
quality of certain Municipal Securities having variable interest rates and
demand features that permit the Trust 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

         The Trust has qualified and intends to remain qualified for the
special tax treatment accorded regulated investment companies under the
Internal Revenue Code of 1986, as amended (the "Code").  The Code permits a
regulated investment company which invests in Municipal Securities the interest
on which is excluded from gross income for federal income tax purposes to pay
to its shareholders "exempt-interest dividends," which are excluded from gross
income for federal income tax purposes, if at the close of each quarter at
least 50 percent of the value of its total assets consist of Municipal
Securities.

         In order to qualify as a regulated investment company, the Trust 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 stock, securities, or
currencies; derive less than 30% of its gross income from the sale or other
disposition of stock, 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
specifically applicable to regulated investment companies, the Trust must
distribute to its shareholders at least 90% of its investment company taxable
income for the year and at least 90% of its interest income that is excluded
from gross income for federal income tax purposes, net of certain deductions.
In general, the Trust'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.

         An exempt-interest dividend is any dividend or part thereof (other
than a capital gain dividend) paid by the Trust that is derived from interest
received by the Trust that is excluded from gross income for federal income tax
purposes, net of certain





                                      B-23
<PAGE>   206
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 the Trust's taxable year.  The percentage of the total dividends paid
by the Trust 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 the Trust'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 the Trust.  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.

         If the distributions from the Trust are less than the sum of 98% of
the Trust's ordinary income for a calendar year plus 98% of the Trust's capital
gain net income for the one-year period ending on October 31 of the calendar
year, the Trust will be subject to a non- deductible 4% excise tax on the
deficit.  The Trust does not intend to incur any excise tax and may make
special distributions to shareholders in order to avoid such tax.

         In general, interest on indebtedness incurred or continued by a
shareholder to purchase or carry Trust Shares is not deductible for federal
income tax purposes if the Trust distributes exempt-interest dividends during
the shareholder's taxable year.  A shareholder of the Trust that is a financial
institution may not deduct interest expense attributable to indebtedness
incurred or continued to purchase or carry Shares of the Trust if the Trust
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 the Trust 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 the Trust.

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





                                      B-24
<PAGE>   207
Trust Shares.  Any such distributions will be designated as a capital gain
dividend in a written notice mailed by the Trust to the shareholders not later
than sixty days after the close of the Trust'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 the Trust will also be treated as tax preference items in
computing the alternative minimum tax to the extent that distributions by the
Trust 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 the Trust 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 the Trust 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.

         The Trust may acquire variable rate demand Municipal Securities and
"stand-by commitments" or "puts" from bond and municipal securities dealers.
See "INVESTMENT OBJECTIVE AND POLICIES - Stand-By Commitments."  With respect
to each such acquisition, an opinion of counsel will be issued that the Trust
will be treated for federal income tax purposes as the owner of the Municipal
Securities acquired subject to such demand features or to such stand-by
commitments and that the interest on the Municipal Securities will be excluded
from the gross income of the Trust for federal income tax purposes.  The
purchase prices of Municipal Securities subject to stand-by commitments must be
allocated





                                      B-25
<PAGE>   208
between such securities and stand-by commitments based upon their respective
fair-market values.

         Distributions of exempt-interest dividends by the Trust 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.  The Trust 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 the Trust during the preceding year.  Shareholders are
advised to consult their tax advisers concerning the application of state and
local taxes.

         The Trust may be required by federal law to withhold and remit to the
U.S. Treasury 31% of taxable dividends, if any, and capital gain distributions
to any shareholder, and the proceeds of any redemption or the values of any
exchanges of Shares of the Trust, if such shareholder (1) fails to furnish the
Trust with a correct taxpayer identification number, (2) under-reports dividend
or interest income, or (3) fails to certify to the Trust that he or she is not
subject to such withholding.  An individual's taxpayer identification number is
his or her Social Security number.

         The foregoing is only a summary of some of the important federal tax
considerations generally affecting the Trust and its shareholders.  No attempt
is made to present a detailed explanation of the federal income tax treatment
of the Trust or its shareholders, and this discussion is not intended as a
substitute for careful tax planning.  Accordingly, potential investors in the
Trust are urged to consult their tax advisers with specific reference to their
own tax situation.

         Information as to the federal income tax status of all distributions
will be mailed annually to each shareholder.


                                     YIELD

         The current (average annualized) yield of the Trust for any seven-day
period is calculated by dividing the average daily net income per Share earned
by the Trust during the seven-day calendar period by the Trust'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 Trust's
portfolio.  The yield of the Trust for the seven-day period ended September 30,
1995, was 3.45%.





                                      B-26
<PAGE>   209
         The effective or compounded yield of the Trust for any seven-day
period is computed by adding the number one to the daily net income per Share
earned by the Trust 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.  The effective or compounded yield of the Trust for the seven-day
period ended September 30, 1995, was 3.51%.

         For the base period, the tax-equivalent yield of the Trust was 5.71%
(using a federal income tax rate of 39.6%) and its tax-equivalent effective
yield was 5.81% (using a federal income tax rate of 39.6%).  The Trust's
tax-equivalent yield was computed by dividing that portion of the Trust's yield
which is tax-exempt by 1 minus the stated income tax rate and adding the result
to that portion, if any, of the Trust's yield that is not tax-exempt.  The
Trust's tax-equivalent effective yield was 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 the Trust's effective yield
that is not tax- exempt.

         Investors may judge the performance of the Trust 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. and Standard
& Poor's Corporation, and to data prepared by Lipper Analytical Services, Inc.,
a widely recognized independent service which monitors the performance of
mutual funds, CDA Investment Technologies, Inc. and the Consumer Price Index.
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, Business Week, The Columbus Dispatch, Consumer
Reports and U.S.A. Today.

         Current and effective yields will fluctuate from time to time and
should not be considered representative of future results.  Yield is a function
of general economic and money market conditions, portfolio quality and
maturity, type of portfolio instruments and operating expenses.  Yield
information may be useful in reviewing the Trust's performance and comparing an
investment in Shares of the Trust with other investment alternatives.  However,
yield on shares of the Trust fluctuates unlike yields on bank deposits or other
instruments that pay a fixed yield for a stated period of time.


                             ADDITIONAL INFORMATION

Shareholder and Trustee Liability
- - ---------------------------------

         The Trust is an entity of the type commonly known as a "business
trust" and is organized under Chapter 1746 of the Ohio





                                      B-27
<PAGE>   210
Revised Code which limits the liability of its shareholders to the assets of
the Trust.  The Declaration of Trust also provides that shareholders shall not
be subject to any personal liability for the acts or obligations of the Trust
and that every agreement, obligation or instrument entered into or executed by
the Trust shall contain a provision to the effect that the shareholders are not
personally liable thereunder.  The Trust has been advised by counsel that
courts in jurisdictions other than Ohio should apply Ohio law in determining
the liability of shareholders of the Trust and that shareholder liability
accordingly will be limited to the assets of the Trust.

         The Declaration of Trust further provides that no Trustee, officer or
agent of the Trust shall be personally liable to any person for any action or
failure to act except for his own bad faith, willful misfeasance, gross
negligence or reckless disregard of his duties.  It also provides that all
persons having any claim against the Trustees or the Trust shall look solely to
the Trust's property for payment.

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

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

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

NOTES TO FINANCIAL STATEMENTS
- - --------------------------------------------------------------------------------
 
SEPTEMBER 30, 1995
 
(1) -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Cardinal Tax Exempt Money Trust (the Trust) is a diversified, open-end
investment company created under the laws of Ohio by a Declaration of Trust
dated January 13, 1983 and is registered under the Investment Company Act of
1940. The following is a summary of significant accounting policies followed by
the Trust in the preparation of its financial statements. The policies are in
conformity with generally accepted accounting principles for investment
companies.
 
Security Valuation--Securities are valued at amortized cost which approximates
fair value (premiums and discounts are amortized on a straight-line basis). The
use of this method requires the Trust to maintain a dollar-weighted average
portfolio maturity of 90 days or less and purchase only securities having a
remaining maturity of thirteen months or less.
 
Variable Rate Demand Municipal Securities--Variable and adjustable 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, at
redemption dates provided by contract 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 interest rates shown for
variable rate securities are the rates in effect on September 30, 1995.
 
Security Transactions and Investment Income--Security transactions are recorded
on the trade date. Interest income is recorded on the accrual basis.
 
Federal Income Taxes--No provision has been made for Federal taxes on the
Trust's income, since it is the policy of the Trust to comply with the
provisions of the Internal Revenue Code applicable to regulated investment
companies and to make sufficient distributions of taxable income and capital
gains within the required time to relieve it from all, or substantially all,
Federal income taxes.
 
Dividends to Shareholders--Dividends are declared and accrued daily and (for
those shareholders not electing cash distribution of dividends) automatically
reinvested monthly in additional shares from the sum of net investment income
and net realized short-term gains.
 
(2) -- TRANSACTIONS WITH AFFILIATES
 
As investment manager for the Trust, Cardinal Management Corp. (CMC), an
affiliated company, is allowed an annual fee of 0.5% of the average daily net
assets of the Trust. CMC has agreed that if the aggregate expenses of the Trust,
as defined, for any fiscal year exceed the expense limitation of any state
having jurisdiction over the Trust, CMC will refund to the Trust, or otherwise
bear, such excess. This limitation did not affect the calculation of the
management fee during the year ended September 30, 1995.
 
CMC also serves as the Trust's transfer agent and fund accountant. Transfer
agent service fees are based on a monthly charge per shareholder account plus
out-of-pocket expenses. Accounting service fees are based on the monthly average
net assets of the Trust. For the year ended September 30, 1995 the Trust paid or
accrued $62,542 and $17,235 for transfer agent and fund accounting services,
respectively.
                                                                     (continued)

SEPTEMBER 30, 1995
 
The Ohio Company, sole shareholder of CMC, serves as the Trust's distributor
and, in connection therewith receives purchase orders and redemption requests
relating to Trust shares. During the year ended September 30, 1995 the Trust
incurred no expenses relating to the distribution of its shares.
 
(3) -- COMMITMENTS AND CONTINGENCIES
 
The Trust has an available $5,000,000 line of credit with its custodian, Fifth
Third Bank, which was unused at September 30, 1995. When used, borrowings under
this arrangement are secured by portfolio securities and can be used only for
short term needs of the Trust. No compensating balances are required and the
arrangement bears an interest rate of 106% of the custodian's prime lending
rate.
 
Fidelity Bond and Errors and Omissions insurance coverage for the Trust and its
officers and trustees has been obtained through ICI Mutual Insurance Company
(ICI Mutual), an industry-sponsored mutual insurance company. Included in other
assets of the Trust is a deposit of $13,291 for the initial capital of ICI
Mutual. The Trust is also committed to provide $39,873 should ICI Mutual
experience the need for additional capital contributions.
 
Included in other assets is a $27,000 certificate of deposit which
collateralizes a standby letter of credit in connection with the Trust's
participation in ICI Mutual. This amount is not available for investment.

(5) -- SUBSEQUENT EVENT
 
On November 13, 1995 the Board of Trustees approved an Agreement and Plan of
Reorganization and Liquidation between the Trust and The Cardinal Group ("TCG").
The plan calls for the transfer of all assets and liabilities of the Trust to a
series of TCG with the same basic investment objectives and restrictions. The
Trustees have determined that this action is in the best interests of the
shareholders of the Trust and TCG. Shareholder approval will be sought and is
needed to ratify the transaction.

INDEPENDENT AUDITORS' REPORT
- - --------------------------------------------------------------------------------
 
The Shareholders and Board of Trustees
Cardinal Tax Exempt Money Trust:
 
We have audited the accompanying statement of assets and liabilities of Cardinal
Tax Exempt Money Trust (the Trust), including the statement of investments, as
of September 30, 1995, and the related statement of operations for the year then
ended, the statements of changes in net assets for each of the years in the
two-year period then ended and the financial highlights for each of the years in
the five-year period then ended. These financial statements and financial
highlights are the responsibility of the Trust's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included verification of securities owned as of
September 30, 1995, by confirmation with the custodian and other appropriate
audit procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Cardinal Tax Exempt Money Trust as of September 30, 1995, the results of its
operations for the year then ended, the changes in its net assets for each of
the years in the two-year period then ended, and the financial highlights for
each of the years in the five-year period then ended, in conformity with
generally accepted accounting principles.

                                    APPENDIX

                       RATINGS OF PERMISSIBLE INVESTMENTS

         Set forth below are excerpts from Moody's Investors Service and
Standard & Poor's Corporation ratings of obligations that are permissible
investments for the Trust.

         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.

         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.

         To provide more detailed indications of credit quality, the ratings of
AA 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 two 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 edge."  Interest payments are protected by a
large or by an exceptionally stable margin and principal is secure.  While the





                                      A-1
<PAGE>   220
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.

         Moody's applies numerical modifiers (1, 2, and 3) with respect to
bonds rated Aa.  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.

Municipal Obligations Ratings
- - -----------------------------

         The following summarizes the two highest ratings used by Moody's for
state and municipal short-term obligations.  Obligations bearing MIG-1 and
VMIG-1 designations are of the best quality, enjoying strong protection by
established cash flows, superior liquidity support or demonstrated broadbased
access to the market for refinancing. Obligations rated "MIG-2" or "VMIG-2"
denote high quality with ample margins of protection although not so large as
in the preceding rating group.

         S&P SP-1 and SP-2 municipal note ratings (the two highest ratings
assigned) are described as follows:

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

                 "SP-2":  Satisfactory capacity to pay principal and interest.

         The following summarizes the two highest ratings used by Moody's for
state and municipal bonds:

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

                 "Aa":  Bonds judged to be of high quality by all standards.

                 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.

         The following summarizes the two highest ratings used by S&P for state
and municipal bonds:

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

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

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