A BRIEF PREVIEW OF THE FUNDS

WHAT ARE THE GOALS OF THE FUNDS?

The Funds are designed to produce high current income with liquidity and
stability of principal. Each Fund will use its best efforts to maintain a
constant net asset value of $1.00 per share, although there is no guarantee that
the Funds will be able to do so. Please read about each Fund before investing.

WHAT ARE THE FUNDS' INVESTMENT STRATEGIES?

The Funds will invest only in U.S. dollar-denominated securities, will maintain
an average maturity on a dollar-weighted basis of 90 days or less, and will
acquire only "eligible securities" that present minimal credit risks and have a
maturity of 397 days or less. The Funds intend to comply with Rule 2a-7 under
the Investment Company Act of 1940. An investment in the Funds is not a deposit
of Bank One Corporation or its affiliates and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency.

WHAT ARE THE MAIN RISKS OF INVESTING IN THE FUNDS?

The U.S. Government Securities Money Market Fund invests in securities that are
backed by "credit enhancements" such as letters of credit. The value of
investments in the Fund could decrease if the credit quality of the credit
enhancement provider declines. In addition, the U.S. Government Securities Money
Market Fund invests in mortgage-related securities which have significantly
greater price and yield volatility than traditional fixed income securities. For
more information about risks, please read "More About the Funds" and "Investment
Risks."

WHAT CLASSES OF SHARES ARE AVAILABLE?

Each Fund currently offers Class A, Class C, Class I and Service Class shares.
Class A and Class C shares are offered to the general public. Class I shares are
offered to institutional investors, including affiliates of Bank One Corporation
and any bank, depository institution, insurance company, pension plan or other
organization authorized to act in fiduciary, advisory, agency, custodial or
similar capacities. Class I shares are not available to Individual Retirement
Accounts ("IRA"). Service Class shares are offered to entities purchasing such
shares on behalf of investors requiring additional administrative or accounting
services such as sweep processing.

HOW DO I PURCHASE AND REDEEM SHARES?

You may buy and redeem shares of the Funds on any day that the Funds are open
for business. Purchase and redemption procedures are explained in greater detail
in "How To Do Business With One Group Mutual Funds." For additional information,
call The One Group Services Company at 1-800-480-4111 or visit One Group Mutual
Fund's web site at www.onegroup.com.

HOW ARE DIVIDENDS PAID?

Generally, dividends are declared on each business day and are distributed
monthly. Any capital gains are distributed at least annually. Distributions are
paid in additional shares of the same class unless you elect to take the payment
in cash. For a more detailed discussion of dividends, see "Dividend Policies."

WHO MANAGES THE FUNDS?

Banc One Investment Advisors Corporation ("Banc One Investment Advisors"), an
indirect subsidiary of Bank One Corporation, serves as the advisor of the Funds.
Banc One Investment Advisors is paid a fee for its services. A more detailed
discussion regarding Banc One Investment Advisors, its services and compensation
can be found in the Prospectus under the headings "The Advisor" and "Shareholder
Expenses."

(1)      If you buy or sell shares through a Shareholder Servicing Agent, you

         classes of shares.

(3)      Due to 12b-1 fees, long-term Class A, Class C and Service Class
         shareholders may pay more than the equivalent of the maximum front-end
         sales charges permitted under the rules of the National Association of
         Securities Dealers. Without the voluntary waiver, 12b-1 fees would be
         .75% for Service Class shares.

(4)      Without the voluntary reduction of Investment Advisory and 12b-1 fees,
         Total Operating Expenses would be .80% for Class A shares, 1.55% for
         Class C shares, 1.30% for Service Class shares, and .55% for Class I
         shares.

Because of the nature of the shares, shareholders are not expected to remain in
Service Class shares for more than a very limited period of time. However, a
shareholder investing in Service Class shares on a continual basis for a period
of one month would pay $1, three months would pay $3, and one year would pay
$11. Without the voluntary fee reduction, that shareholder would pay $1 after
one month, $3 after three months, and $13 after one year.

These examples are designed to assist you in understanding the various costs and
expenses that may be directly or indirectly paid by investors in the Fund. THESE
EXAMPLES SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES

MORE ABOUT THE FUNDS

PORTFOLIO QUALITY

Securities will be purchased by the Funds only if Banc One Investment Advisors
determine that they present minimal credit risk under guidelines adopted by the
One Group Board of Trustees. In addition, unless a more specific rating is
specified, all investments of the Funds must be rated in one of the three
highest rating categories described in "Description of Ratings" in the Appendix.
If an investment is unrated, Banc One Investment Advisors must determine that it
is of comparable quality to a rated security. Banc One Investment Advisors will
look at a security's rating at the time of investment. For more information
about ratings, please see "Description of Ratings" in the Appendix.

ILLIQUID INVESTMENTS

Each Fund may invest up to 10% of its net assets in illiquid investments. A
security is illiquid if it cannot be sold at approximately the value assessed by
the Fund within seven (7) days. Banc One Investment Advisors will follow
guidelines adopted by the Board of Trustees in determining whether an investment
is illiquid.

SPECIAL RISK CONSIDERATIONS

NET ASSET VALUE: There is no assurance that the Funds will meet their investment
objectives or be able to maintain a net asset value of $1.00 per share on a
continuous basis.

PORTFOLIO TURNOVER: The Funds attempt to increase yield by taking advantage of
short-term market variations. This policy is expected to result in high
portfolio turnover. However, this should not adversely affect the Funds because
they usually do not pay brokerage commissions when purchasing U.S. government
securities.

FIXED INCOME SECURITIES: Investments in fixed income securities (for example,
bonds) will increase or decrease in value based on changes in interest rates. If
rates increase, the value of a Fund's investments generally declines. On the
other hand, if rates fall, the value of the investments generally increases. The
value of your investment in a Fund will increase and decrease as the value of a
Fund's investments increase and decrease. While securities with longer duration
and maturities tend to produce higher yields, they also are subject to greater
fluctuations in value when interest rates change. Usually changes in the value
of fixed income securities will not affect cash income generated, but may affect
the value of your investment.

DERIVATIVES: The U.S. Government Securities Money Market Fund invests in
securities that are considered to be derivatives. Derivatives are securities or
contracts that derive their value from the performance of underlying assets or
securities. These securities may be more volatile than other securities. These
include mortgage-backed securities, including collateralized mortgage
obligations and Real Estate Mortgage Investment Conduits (CMOs and REMICs).
Derivatives present, to varying degrees, market, credit, leverage, liquidity,
and management risks. The Fund's use of derivatives may cause the Fund to
recognize higher amounts of short-term capital gains (generally taxed at
ordinary income tax rates) than it would if the Fund did not use such
instruments. For a more detailed discussion of these risks, please read
"Investment Risks."

HOW TO DO BUSINESS WITH ONE GROUP MUTUAL FUNDS

PURCHASING FUND SHARES

WHERE CAN I BUY SHARES?

You may purchase Fund shares from the following sources:

o        The One Group Services Company, and

o        Shareholder Servicing Agents. These include investment advisors,
         brokers, financial planners, banks, insurance companies, retirement or
         401(k) plan sponsors, or other intermediaries. Shares purchased this
         way will be held for you by the Shareholder Servicing Agent.

WHEN CAN I BUY SHARES?

o        Purchases may be made on any business day. This includes any day that
         the Funds are open for business, other than weekends, days on which the
         New York Stock Exchange ("NYSE") is closed, and the following holidays:
         New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
         Friday, Memorial Day, Independence Day, Labor Day, Columbus Day,
         Veterans Day, Thanksgiving, and Christmas.

o        Purchase requests will be effective on the day received by The One
         Group Services Company and you will be eligible to receive dividends
         declared the same day, if such purchase orders are received by The One
         Group Services Company:

         (i)      before 2:00 p.m., Eastern Time ("ET"), for the Treasury Prime
                  Money Market Fund;

         (ii)     before 4:00 p.m., ET, the U.S. Government Securities Money
                  Market Fund.

         In addition, the Fund's custodian, State Street Bank and Trust Company,
         must receive "federal funds" before 4:00 p.m., ET on such day. If State
         Street Bank and Trust Company does not receive federal funds by the
         cut-off time, the purchase order will not be effective until the next
         business day on which federal funds are timely received by State Street
         Bank and Trust Company.

o        On occasion, the NYSE will close before 4:00 p.m. ET. When that
         happens, purchase requests received after the NYSE closes will be
         effective the following business day.

o        If your shares are held by a Shareholder Servicing Agent, it is the
         responsibility of the Shareholder Servicing Agent to send your purchase
         or redemption order to the Fund. Your Shareholder Servicing Agent may
         have an earlier cut-off time for purchase and redemption requests.

o        The One Group Services Company can reject a purchase order if it does
         not think that it is in the best interests of a Fund and/or its
         shareholders to accept the order.

o        Shares are electronically recorded. Therefore, certificates will not be
         issued.

WHAT KIND OF SHARES CAN I BUY?

One Group offers the following classes of shares:

o        Class A and Class C shares are available to the general public.

o        Class I shares are available to institutional investors and any
         organization authorized to act in a fiduciary, advisory, custodial or
         agency capacity. We will refer to these entities as "Intermediaries."

o        Service Class shares are available to Intermediaries purchasing shares
         on behalf of investors requiring additional administrative or
         accounting services such as sweep processing.

One Group Fund Direct IRA. One Group offers a retirement plan. These plans allow
participants to defer taxes while their retirement savings grow. Call The One
Group Services Company at 1-800-480-4111 for an Adoption Agreement.

HOW MUCH DO SHARES COST?

o        Shares are sold at net asset value ("NAV").

o        NAV per share is calculated by dividing the total market value of a
         Fund's investment and other assets allocable to a class (minus class
         expenses) by the number of outstanding shares in that class. The Funds
         use their best efforts to maintain their NAV at $1.00, although there
         is no guarantee that they will be able to do so.

o        NAV is calculated each business day as of 2:00 p.m., ET, for the
         Treasury Prime Money Market Fund; and 4:00 p.m., ET, for the U.S.
         Government Securities Money Market Fund. On occasion, the NYSE will
         close before 4:00 p.m. ET. When that happens, NAV will be calculated as
         of the time the NYSE closes.

HOW DO I OPEN AN ACCOUNT?

1.       Read the prospectus carefully, and select the Fund or Funds most
         appropriate for you.

2.       Decide how much you want to invest.

         o        The minimum initial investment is $1,000 ($100 for employees
                  of BANK ONE CORPORATION and its affiliates). The minimum
                  initial investment for an IRA is $250.

         o        Subsequent investments must be at least $100 ($25 for
                  employees of BANK ONE CORPORATION and its affiliates).

         o        The One Group Services Company may waive these minimums.

3.       Complete the Account Application Form. Be sure to sign up for all of
         the Account privileges that you plan to take advantage of. Doing so now
         means that you will not have to complete additional paperwork later.

4.       Send the completed application and a personal check (unless you choose
         to pay by wire or bank transfer) payable to "One Group" to:

         State Street Bank and Trust Company
         c/o One Group
         P.O. Box 8528
         Boston, MA 02266-8528

         Contributions to Fund Direct IRAs should be made payable to "State

CAN I AUTOMATICALLY INVEST ON A SYSTEMATIC BASIS?

Yes. After your Account is established, you may purchase additional Class A and
Class C shares by making automatic monthly investments from your bank account.
The minimum initial investment is still $1,000, but minimum automatic additions
are only $25. The One Group Services Company may waive these minimums. To

         charge in the future. However, your bank may impose a charge for
         debiting your bank account.

o        You may revoke your right to make systematic investments by calling The
         One Group Services Company at 1-800-480-4111 or by sending a letter to:

MAY I WRITE CHECKS ON MY ACCOUNT?

Class A shareholders may write checks for $250 or more.

o        Checks may be payable to any person and your account will continue to
         earn dividends until the check clears.

o        Checks are free, but your bank or the payee may charge you for stop
         payment orders, insufficient funds, or other valid reasons.

o        You can not use this option to close your account because of the
         difficulty of determining the exact value of your account.

SALES CHARGES

The One Group Services Company compensates Shareholder Servicing Agents who sell
shares of One Group. Compensation comes from sales charges, 12b-1 fees and
payments by The One Group Services Company from its own resources. Occasionally,
The One Group Services Company, at its own expense, also will provide cash
incentives to select Shareholder Servicing Agents. Those Shareholder Servicing
Agents who may receive special incentives include Banc One Securities
Corporation, The Advisors Group, United Planners Financial Services of America,
Inc., The Legend Group, and Rosewood Retirement Advisory Services, LLC.


CLASS C SHARES

Class C shares are offered at NAV, without any up-front sales charge. However,
if you redeem your shares within one year of the purchase date, you will be
assessed a CDSC as follows:

<TABLE>
<CAPTION>
                                                                      CDSC AS A % OF DOLLAR
         YEARS SINCE PURCHASE                                       AMOUNT SUBJECT TO CHARGE
         --------------------                                       ------------------------
         <S>                                                        <C>
                 0-1                                                          1.00%
           After first year                                                   none
</TABLE>

The One Group Services Company pays a commission of 1.00% of the original
purchase price to Shareholder Servicing Agents who sell Class C shares.

How the CDSC is Calculated

o        The Fund assumes that all purchases made in a given month were made on
         the first day of the month.

o        The CDSC is based on the net amount redeemed.

o        A sales charge is not assessed on shares acquired through reinvestment
         of dividends or capital gains distributions.

o        To keep your CDSC as low as possible, the Fund first will redeem any
         shares in your account that carry no CDSC, starting with Class A
         Shares. After that, the Fund will redeem the shares you have held for
         the longest time and thus have the lowest CDSC.

o        If you exchange Class C shares of an unrelated mutual fund for Class C
         shares of One Group in connection with a fund reorganization, the CDSC
         applicable to your original shares (including the period of time you
         have held those shares) will be applied to One Group shares you receive
         in the reorganization.

12b-1 FEES

12b-1 fees are paid by One Group to The One Group Services Company as
compensation for its services and expenses. The One Group Services Company in
turn pays all or part of the 12b-1 fee to brokers and other Shareholder
Servicing Agents that sell shares of One Group.

o        The 12b-1 fees vary by share class as follows:


                                       13
<PAGE>   17


         1.       Class A shares pay a 12b-1 fee of .25% of the average daily
                  net assets of the Fund.

         2.       Class C shares pay a 12b-1 fee of 1.00% of the average daily
                  net assets of the Fund. This will cause expenses for Class C
                  shares to be higher and dividends to be lower than for Class A
                  shares.

         3.       Service Class shares pay a 12b-1 fee of .75% of the average
                  daily net assets of the Fund, which is currently being waived
                  to .55% for each Fund.

         4.       There are no 12b-1 fees for Class I shares.

o        12b-1 fees, together with the CDSC, help The One Group Services Company
         sell Class C shares without an "up-front" sales charge by defraying the
         costs of advancing brokerage commissions and other expenses paid to
         Shareholder Servicing Agents.

o        The One Group Services Company may use up to .25% of the fees for
         shareholder servicing and up to .75% for distribution. During the last
         fiscal year, The One Group Services Company received 12b-1 fees.

o        The One Group Services Company may pay 12b-1 fees to its affiliates and
         to Banc One Investment Advisors and its affiliates (or any sub-advisor)
         for brokerage and other agency transactions.

SALES CHARGE REDUCTIONS AND WAIVERS

WAIVER OF THE CLASS C SALES CHARGE

No sales charge is imposed on redemptions of Class C shares of the Funds:

1.       Provided that you withdraw no more than 10% of the account value
         annually. You do not have to participate in the Systematic Withdrawal
         Plan to take advantage of this waiver.

2.       If you buy the shares in connection with certain retirement plans, such
         as 401(k) and similar qualified plans.

3.       If you are the shareholder (or a joint shareholder), or a participant
         or beneficiary of certain retirement plans and you die or become
         disabled (as defined by the Tax Code), but only if the redemption is
         made within one year of such death or disability.

4.       That represent a minimum required distributions from an IRA Account or
         other qualifying retirement plan, but only if you are at least age 70
         1/2.

5.       Exchanged in connection with plans of reorganizations of a Fund, such
         as mergers, asset acquisitions and exchange offers to which a Fund is a
         party.

6.       Acquired in exchange for Class C shares of other One Group Funds.

7.       If The One Group Services Company receives notice before you invest
         indicating that your Shareholder Servicing Agent, due to the type of
         account that you have, is waiving its commission.

To take advantage of any of these sales charge waivers, you must qualify for
such waiver in advance. To see if you qualify, contact The One Group Services
Company at 1-800-480-4111 or your Shareholder Servicing Agent.


EXCHANGING FUND SHARES

WHAT ARE MY EXCHANGE PRIVILEGES?

You may make the following exchanges:

o        Class I shares of a Fund may be exchanged for Class A shares of that
         Fund or for Class A or Class I shares of another One Group Fund.



                                       14
<PAGE>   18


o        Class A shares of a Fund may be exchanged for Class I shares of that
         Fund or for Class A or Class I shares of another One Group Fund, but
         only if you are eligible to purchase those shares.

o        Class C shares of a Fund may be exchanged for Class C shares of another
         One Group Fund.

o        Service Class shares do not have exchange privileges.

One Group offers a Systematic Exchange Privilege which allows you to
automatically exchange shares of one fund to another on a monthly or quarterly
basis. This privilege is useful in dollar cost averaging. To participate in this
privilege, please select it on your account application. To learn more about it,
please call The One Group Services Company at 1-800-480-4111.

One Group may change the terms and conditions of your exchange privileges upon
60 days written notice. One Group does not charge a fee for this privilege.

WHEN ARE EXCHANGES PROCESSED?

Exchanges are processed the same business day they are received, provided:

o        State Street Bank and Trust Company receives the request by 4:00 p.m.
         ET.

o        You have provided One Group with all of the information necessary to
         process the exchange.

o        You have received a current prospectus of the Fund or Funds into which
         you wish to invest.

o        You have contacted your Shareholder Servicing Agent, if necessary.

DO I PAY A SALES CHARGE ON AN EXCHANGE?

Generally, you will not pay a sales charge on an exchange. However:

o        You will pay a sales charge if you own Class I shares of a Fund and you
         want to exchange those shares for Class A shares, unless you qualify
         for a sales charge waiver.

o        You will pay a sales charge if you bought Class A shares of a Fund:

         1.       That does not charge a sales charge and you want to exchange
                  them for shares of a Fund that does, in which case you would
                  pay the sales charge applicable to the Fund into which you are
                  exchanging.

         2.       That charged a lower sales charge than the Fund into which you
                  are exchanging, in which case you would pay the difference
                  between that Fund's sales charge and all other sales charges
                  you have already paid.

o        If you exchange Class C shares of a Fund, you will not pay a sales
         charge at the time of the exchange, however:

         1.       Your new Class C shares will be subject to the higher CDSC of
                  either the Fund from which you exchanged, the Fund into which
                  you exchanged, or any Fund from which you previously
                  exchanged.

         2.       The current holding period for your exchanged Class C shares
                  is carried over to your new shares.

ARE EXCHANGES TAXABLE?

Generally:

o        An exchange between classes of shares of the same Fund is not taxable
         for Federal income tax purposes.

o        An exchange between Funds is considered a sale and generally results in
         a capital gain or loss for Federal income tax purposes.


                                       15
<PAGE>   19


o        You should talk to your tax advisor before making an exchange.

ARE THERE LIMITS ON EXCHANGES?

Yes. The exchange privilege is not intended as a way for you to speculate on
short-term movements in the market. Therefore:

o        To prevent disruptions in the management of the Funds, One Group limits
         excessive exchange activity.

o        Exchange activity is excessive if it EXCEEDS TWO SUBSTANTIVE EXCHANGE
         REDEMPTIONS (WITHIN 30 DAYS OF EACH OTHER) WITHIN A TWELVE MONTH
         PERIOD.

o        In addition, One Group reserves the right to reject any exchange
         request (even those that are not excessive) if the Fund reasonably
         believes that the exchange will result in excessive transaction costs
         or otherwise adversely affect other shareholders.

REDEEMING FUND SHARES

WHEN CAN I REDEEM SHARES?

o        You may redeem all or some of your shares on any day that the Funds are
         open for business.

o        Redemption requests received by The One Group Services Company before
         4:00 p.m. ET (or when the NYSE closes), will be effective that day.

HOW DO I REDEEM SHARES?

o        Unless you have selected the telephone option on your Account
         Application Form, you must send a written redemption request to your
         Shareholder Servicing Agent, if applicable, or to State Street Bank and
         Trust Company at the following address:

         State Street Bank and Trust Company
         c/o One Group
         P.O. Box 8528
         Boston, MA 02266-8528

o        All requests for redemptions from IRA accounts must be in writing.

o        You may request redemption forms by calling The One Group Services
         Company at 1-800-480-4111.

o        State Street Bank and Trust Company may require that the signature on
         your redemption request be guaranteed by a commercial bank, a member of
         a domestic stock exchange, or a member of the Securities Transfer
         Association Medallion Program or the Stock Exchange Medallion Program,
         unless:

         1.       the redemption is for $50,000 worth of shares or less;

         2.       the redemption is payable to the shareholder of record;

         3.       the redemption check is mailed to the shareholder at the
                  record address; or

         4.       the redemption is payable by wire or bank transfer (ACH) to a
                  pre-existing bank account.

o        On the Account Application Form you may elect to have the redemption
         proceeds mailed or wired to:

         1.       a designated commercial bank; or

         2.       State Street Bank and Trust Company or your Shareholder
                  Servicing Agent.

o        State Street Bank and Trust Company may charge you a wire redemption
         fee. The current charge is $7.00.



                                       16
<PAGE>   20


o        Your redemption proceeds will ordinarily be paid within seven days
         after receipt of the redemption request. If you have wire instructions
         on file, the Funds will attempt to honor requests for same day payment,
         if the request is received before 2:00 p.m. ET for the Treasury Prime
         Money Market Fund and 4:00 p.m. ET for the U.S. Government Securities
         Money Market Fund. If redemption requests are received after these
         times, the Funds will attempt to wire payment the next business day.

o        The Funds also will attempt to honor requests for payments in two
         business days, if the redemption request is received after the times
         listed above.

WHAT WILL MY SHARES BE WORTH?

o        The NAV of shares of the Funds is expected to remain constant at $1.00
         per share, although there is no assurance that this will always be the
         case.

o        If you own Class A, Service Class or Class I shares, you will receive
         the NAV calculated after your redemption request is received. Please
         read "How Much Do Shares Cost?"

o        If you own Class C shares, you will receive the NAV calculated after
         your redemption request is received, minus the amount of any applicable
         CDSC.

CAN I REDEEM BY TELEPHONE?

Yes, if you selected this option on your Account Application Form.

o        Call your Shareholder Servicing Agent or The One Group Services Company
         at 1-800-480-4111 to relay your redemption request.

o        Your redemption proceeds will be mailed or wired to the commercial bank
         account you designated on your Account Application Form.

o        State Street Bank and Trust Company may charge you a wire redemption
         fee. The current charge is $7.00.

o        One Group uses reasonable procedures to confirm that instructions given
         by telephone are genuine. These procedures include recording telephone
         instructions and asking for personal identification. If these
         procedures are followed, One Group will not be responsible for any
         loss, liability, cost or expense of acting upon unauthorized or
         fraudulent instructions; you bear the risk of loss.

o        REDEMPTIONS FROM YOUR IRA ACCOUNT MAY NOT BE MADE BY TELEPHONE.

CAN I REDEEM ON A SYSTEMATIC BASIS?

If you have an account value of at least $10,000 you may elect to receive
monthly, quarterly or annual payments of not less than $100 each.

o        Select the "Systematic Withdrawal Plan" option on the Account
         Application Form.

o        Specify the amount you wish to receive and the frequency of the
         payments.

o        You may designate a person other than yourself as the payee.

o        There is no charge for this service.

o        If you select this option, please keep in mind that:

         1.       If you own Class C shares, you or your designated payee may
                  receive systematic payments provided the payments are limited
                  to no more than 10% of your account value annually, measured
                  from the date the redemption request is received.

         2.       If you are age 70-1/2, you may elect to receive payments to
                  the extent that the payment represents a minimum required
                  distribution from an IRA or other qualifying retirement plan.
                  You also may elect to receive payments of less than $100 each.


                                       17
<PAGE>   21


         3.       If the amount of the systematic payment exceeds the income
                  earned by your account since the previous payment under the
                  Systematic Withdrawal Plan, payments will be made by redeeming
                  some of your shares. This will reduce the amount of your
                  investment.

ADDITIONAL INFORMATION REGARDING REDEMPTIONS

o        All redemptions will be for cash. The redemption price of shares is
         expected to remain constant at $1.00 per share, although there is no
         assurance that this will always be the case.

o        If you redeem shares for which you paid by check, and One Group has not
         yet received payment on the check, One Group will delay forwarding your
         redemption proceeds for 10 or more days until payment has been
         collected from your bank.

o        Because of the high cost of handling small investments, One Group
         charges a sub-minimum account fee. Accounts under $1,000 that are not
         participating in a Systematic Investment Plan will be assessed an
         annual fee of $10.00. The sub-minimum account fee will not apply to IRA
         accounts and the accounts of employees of Bank One Corporation and its
         affiliates.

o        One Group may suspend your ability to redeem when:

         1.       Trading on the NYSE is restricted;

         2.       the NYSE is closed (other than weekend and holiday closings);

         3.       the SEC has permitted a suspension; or

         4.       an emergency exists.

The Statement of Additional Information offers more details about this process.

o        You generally will recognize a gain or loss on a redemption for Federal
         income tax purposes. You should talk to your tax advisor before making
         a redemption.

SHAREHOLDER INFORMATION

VOTING RIGHTS

The Funds do not hold annual shareholder meetings, but may hold special
meetings. The special meetings are held, for example, to elect or remove
Trustees, change a Fund's fundamental investment objective, or approve an
investment advisory contract.

As a Fund shareholder, you have one vote for each share that you own. Each Fund,
and each class of shares within each Fund, vote separately on matters relating
solely to that Fund or class, or which affect that Fund or class differently.
However, all shareholders will have equal voting rights on matters that affect
all shareholders equally.

DIVIDEND POLICIES

DIVIDENDS

The Funds generally declare dividends on each business day. Dividends are
distributed on the first business day of each month. Capital gains, if any, for
all Funds are distributed at least annually.

Dividends payable on Class I shares will be more than those payable on other
classes of shares. This is because Class A, Class C and Service Class shares
have higher distribution expenses.

DIVIDEND REINVESTMENT

You automatically will receive all income dividends and capital gain
distributions in additional shares of the same Fund and class, unless you have
elected to take such payment in cash. The price of the shares is the NAV
determined immediately following the dividend record date. Reinvested dividends
and distributions receive the same tax treatment as dividends and distributions
paid in cash.

If you want to change the way in which you receive dividends and distributions,
you must write to State Street Bank & Trust Company at P.O. Box 8528, Boston, MA
02266-8528, at least 15 days prior to the distribution. The change is effective
upon receipt by State Street. You also may change the way you receive dividends
and distributions by calling The One Group Services Company at 1-800-480-4111.

TAX TREATMENT OF THE FUNDS

TAX STATUS OF THE FUND

Each Fund intends to qualify as a "regulated investment company" for Federal
income tax purposes. If the Funds qualify, as they have in the past, they will
pay no federal income tax on the earnings they distribute to shareholders.

TAX TREATMENT OF SHAREHOLDERS

TAXATION OF SHAREHOLDER TRANSACTIONS

A sale, exchange, or redemption of Fund shares may produce either a taxable gain
or a loss. You are responsible for any tax liabilities generated by your
transactions.

TAXATION OF DISTRIBUTIONS

Each Fund will distribute substantially all of its net investment income
(including, for this purpose, the excess, if any, of net short-term capital
gains over net long-term capital losses) and, if any, net capital gains (i.e.,
the excess, if any, of net long-term capital gains over net short-term capital
losses) to investors on at least an annual basis. Dividends you receive from a
Fund, whether reinvested or received in cash, will be taxable to you. Dividends
from a Fund's net investment income will be taxable as ordinary income and
distributions from a Fund's long-term capital gains will be taxable to you as
such, regardless of how long you have held the shares.

Dividends paid in January, but declared in October, November or December of the
previous year, will be considered to have been paid in the previous year.


TAXATION OF RETIREMENT PLANS

Distributions by the Funds to qualified retirement plans generally will not be
taxable. However, if shares are held by a plan that ceases to qualify for
tax-exempt treatment or by an individual who has received shares as a
distribution from a retirement plan, the distributions will be taxable to the
plan or individual as described in "Taxation of Distributions." If you are
considering purchasing shares with qualified retirement plan assets, you should
consult your tax advisor for a more complete explanation of the Federal, state,
local and (if applicable) foreign tax consequences of making such an investment.

TAX INFORMATION

The Form 1099 that is mailed to you every January details your dividends and
their federal tax category. Even though the Funds provide you with this
information, you are responsible for verifying your tax liability with your tax
professional. For additional tax information see the Statement of Additional
Information. Please note that this tax discussion is general in nature; no
attempt has been made to present a complete explanation of the Federal, state,
local or foreign tax treatment of the Funds or their shareholders.

SHAREHOLDER INQUIRIES

If you have any questions or need additional information, please write The One
Group Services Company at 3435 Stelzer Road, Columbus, OH 43219 or call
1-800-480-4111.

REPORTING

In September and March you will receive a financial report from One Group. In
addition, One Group will periodically send you proxy statements and other
reports.

ORGANIZATION AND MANAGEMENT OF THE FUNDS

THE FUNDS

Each Fund is a series of One Group Mutual Funds, an open-end management
investment company. One Group currently offers 53 separate Funds. Two of the
Funds are described in this prospectus; the other Funds are described in
separate prospectuses. Each Fund is supervised by the Board of Trustees.

THE BOARD OF TRUSTEES

The Trustees oversee the management and administration of the Funds. The
Trustees are responsible for making major decisions about each Fund's investment
objectives and policies, but delegate the day-to-day administration of the Funds
to the officers of One Group.

THE ADVISOR

Banc One Investment Advisors makes the day-to-day investment decisions for the
Funds and continuously reviews, supervises and administers the Funds' investment
programs. Banc One Investment Advisors has served as investment advisor to One
Group since 1993. Prior to that time, One Group was advised by affiliates of
Banc One Investment Advisors. In addition to One Group, Banc One Investment
Advisors serves as investment advisor to other mutual funds and individual,
corporate, charitable and retirement accounts. As of March 29, 1999, Banc One
Investment Advisors, an indirect, wholly-owned subsidiary of Bank One
Corporation managed over $120 billion in assets.

THE DISTRIBUTOR

The One Group Services Company, 3435 Stelzer Road, Columbus, Ohio 43219, a
wholly-owned subsidiary of The BISYS Group, Inc., markets the Funds and
distributes shares through selling brokers, financial institutions, investment
advisors, and other financial representatives.

THE ADMINISTRATOR AND SUB-ADMINISTRATOR

The One Group Services Company also serves as the Funds' administrator. The One
Group Services Company is responsible for responding to shareholder inquiries
and requests for information, as well as providing regulatory compliance and
reporting. For these services, The One Group Services Company receives a fee
based on the total assets of One Group. For the first $1.5 billion in One Group
assets, The One Group Services Company receives an annual fee of .20% of each
Fund's average daily net assets. The annual rate declines to .18% on assets up
to $2 billion, and to .16% when assets exceed $2 billion. The fee is calculated
daily and paid monthly. Some Funds are not included in the calculations. Banc
One Investment Advisors, the Sub-Administrator, provides office space,
equipment, and facilities, as well as legal and regulatory support.

THE TRANSFER AGENT, CUSTODIAN AND THE SUB-CUSTODIAN

State Street Bank and Trust Company, P.O. Box 8528, Boston, MA 02266-8528 or
your Shareholder Servicing Agent, if appropriate, handles shareholder record
keeping and statements, distributes dividends, and processes buy and sell
requests. As the Funds' custodian, State Street holds the Funds' assets, settles
all portfolio trades and assists in calculating the Funds' net asset values.
Bank One Trust Company, N.A. serves as sub-custodian in connection with the
Funds' securities lending activities under an agreement with State Street Bank
and Trust Company. Bank One Trust Company, N.A. is paid a fee for this service.

YEAR 2000

Preparing for the Year 2000 is a high priority for One Group. Both The One Group
Services Company and Banc One Investment Advisors have formed dedicated teams to
help them successfully achieve Year 2000 compliance. In addition, these teams
are responsible for assessing the readiness of all other service providers to
One Group. Year 2000 remediation efforts are directed toward both information
technology and non-information technology systems. Non-information technology
systems include elevators, photocopy machines, and facsimile machines, and
should have no significant impact on the delivery of services to One Group.

Banc One Investment Advisors has identified 49 information technology systems
and interfaces that provide service and support to One Group. Each system is
assigned a priority rating: high, medium or low. Systems rated "high" are those
which are essential to the operation of One Group. Each system rated



                                       21
<PAGE>   25


"high" was scheduled to be Year 2000 compliant by December 31, 1998. All systems
will be tested for compliance throughout 1999.

Many, if not all, of the systems are owned or operated by third party servicers
(for example, One Group's Custodian). Consequently, remediation efforts must be
made by those servicers. Banc One Investment Advisors and The One Group Services
Company have, and will continue to, monitor the remediation progress of the
service providers. This process involves documentation, on-site visits, and
review of remediation plans and test results. Both Banc One Investment Advisors
and The One Group Services Company have budgeted in excess of $700,000 in fiscal
year 1998 and over $1 million in fiscal year 1999 toward the remediation effort
for all systems and interfaces. Neither One Group nor its shareholders will bear
any of the direct remediation expenses.

Neither The One Group Services Company nor Banc One Investment Advisors
currently anticipate that the move to Year 2000 will have a material impact on
their ability to continue to provide the Funds with service at current levels.
Likewise, One Group currently anticipates that the move to Year 2000 will not
have a material impact on its operations.

INVESTMENT RISKS

Below is a more complete discussion of the types of risks inherent in the
securities and investment techniques listed above. Because of these risks, the
value of the securities held by the Funds may fluctuate, as will the value of
your investment in the Funds. Certain investments are more susceptible to these
risks than others.

o        CREDIT RISK. The risk that the issuer of a security, or the
         counterparty to a contract, will default or otherwise become unable to
         honor a financial obligation. Credit risk is generally higher for
         non-investment grade securities. The price and liquidity of a security
         can be adversely affected prior to actual default as its credit status
         deteriorates and the probability of default rises.

o        LEVERAGE RISK. The risk associated with securities or practices (such
         as borrowing) that multiply small index or market movements into large
         changes in value.

o        LIQUIDITY RISK. The risk that certain securities may be difficult or
         impossible to sell at the time and the price that normally prevails in
         the market. The seller may have to lower the price, sell other
         securities instead or forego an investment opportunity, any of which
         could have a negative effect on fund management or performance. This
         includes the risk of missing out on an investment opportunity because
         the assets necessary to take advantage of it are tied up in less
         advantageous investments.

o        MARKET RISK. The risk that the market value of a security may move up
         and down, sometimes rapidly and unpredictably. These fluctuations may
         cause a security to be worth less than the price originally paid for
         it, or less than it was worth at an earlier time. Market risk may
         affect a single issuer, industry, sector of the economy or the market
         as a whole. For fixed income securities, market risk is largely, but
         not exclusively, influenced by changes in interest rates. A rise in
         interest rates typically causes a fall in values, while a fall in rates
         typically causes a rise in values. Finally, key information about a
         security or market may be inaccurate or unavailable. This is
         particularly relevant to investments in foreign securities.

o        PRE-PAYMENT RISK. The risk that the principal repayment of a security
         will occur at an unexpected time, especially that the repayment of a
         mortgage or asset-backed security occurs either significantly sooner or
         later than expected. Changes in pre-payment rates can result in greater
         price and yield volatility. Pre-payments generally accelerate when
         interest rates decline. When mortgage and other obligations are
         pre-paid, a Fund may have to reinvest in securities with a lower yield.
         Further, with early repayment, a Fund may fail to recoup any premium
         paid, resulting in an unexpected capital loss.

o        REGULATORY RISK. The risk associated with Federal and state laws which
         may restrict the remedies that a lender has when a borrower defaults on
         loans. These laws include restrictions on foreclosures, redemption
         rights after foreclosure, Federal and state bankruptcy and debtor
         relief laws, restrictions on "due on sale" clauses, and state usury
         laws.

INVESTMENT POLICIES

Each Fund's investment objective and the following investment policies
summarized below are fundamental. This means that they cannot be changed without
the consent of a majority of the outstanding shares of the Funds. In addition to
the fundamental policies mentioned earlier, the following fundamental policies
apply to each Fund as specified. The full text of the fundamental policies can
be found in the Statement of Additional Information.

FUNDAMENTAL POLICIES OF EACH FUND

Each Fund:

1.       Will use its best efforts to maintain a constant net asset value of
         $1.00 per share, although there is no guarantee that the Funds will be
         able to do so.

2.       Will not, with respect to 75% of a Fund's total assets, purchase the
         securities of an issuer if as a result more than 5% of its total assets
         would be invested in the securities of that issuer or the Fund would
         own more than 10% of the outstanding voting securities of that issuer,
         except as otherwise permitted by applicable law or regulation. This
         does not include securities issued or guaranteed by the United States,
         its agencies or instrumentalities, and repurchase agreements involving
         these securities.

3.       Will not purchase securities while borrowings (including reverse
         repurchase agreements) exceed 5% of the respective Fund's net assets.

4.       Will not borrow money or issue senior securities, except that the Funds
         may borrow from banks for temporary purposes in amounts not exceeding
         10% of their total assets at the time of the borrowing.

5.       Will not mortgage, pledge or hypothecate any assets, except in
         connection with borrowing specified in 4 above and in amounts not in
         excess of the lesser of the dollar amount borrowed or 10% of the value
         of the respective Fund's total assets at the time of its borrowing.

APPENDIX

DESCRIPTION OF RATINGS

The following is a summary of published ratings by major credit rating agencies.
Credit ratings evaluate only the safety of principal and interest payments, not
the market value risk of lower quality securities. Credit rating agencies may
fail to change credit ratings to reflect subsequent events on a timely basis.
Although Banc One Investment Advisors considers security ratings when making
investment decisions, it also performs its own investment analysis and does not
rely solely on the ratings assigned by credit agencies.

Unrated securities will be treated as non-investment grade securities unless
Banc One Investment Advisors determines that such securities are the equivalent
of investment grade securities. Securities that have received different ratings
from more than one agency are considered investment grade if at least one agency
has rated the security investment grade.


DESCRIPTION OF BANK RATINGS

MOODY'S

These ratings represent Moody's opinion of a bank's intrinsic safety and
soundness.

                    A      These banks possess exceptional intrinsic financial
                           strength. Typically they will be major financial
                           institutions with highly valuable and defensible
                           business franchises, strong financial fundamentals,
                           and a very attractive and stable operating
                           environment.

                    B      These banks possess strong intrinsic financial
                           strength. Typically, they will be important
                           institutions with valuable and defensible business
                           franchises, good financial fundamentals, and an
                           attractive and stable operating environment.

                    C      These banks possess good intrinsic financial
                           strength. Typically, they will be institutions with
                           valuable and defensible business franchises. These
                           banks will demonstrate either acceptable financial
                           fundamentals within a stable operating environment,
                           or better than average financial fundamentals within
                           an unstable operating environment.

S&P

S&P's credit rating is a current opinion of an obligor's overall financial
capacity (its creditworthiness) to pay its financial obligation.

                  Aaa      The highest rating assigned by S&P. The obligor's
                           capacity to meet its financial commitment on the
                           obligation is extremely strong.

                   Aa      The obligor's capacity to meet its financial
                           commitments on the obligation is very strong.

                    A      The obligation is somewhat more susceptible to the
                           adverse effects of changes in circumstances and
                           economic conditions than obligations in higher rated
                           categories. However, the obligor's capacity to meet
                           its financial commitment on the obligation is still
                           strong.

DESCRIPTION OF INSURANCE RATINGS

MOODY'S

These ratings represent Moody's opinions of the ability of insurance companies
to pay punctually senior policyholder claims and obligations.

<PAGE>   29


                  Aaa      Insurance companies rated in this category offer
                           exceptional financial security. While the financial
                           strength of these companies is likely to change, such
                           changes as can be visualized are most unlikely to
                           impair their fundamentally strong position.

                   Aa      These insurance companies offer excellent financial
                           security. Together with the Aaa group, they
                           constitute what are generally known as high grade
                           companies. They are rated lower than Aaa companies
                           because long-term risks appear somewhat larger.

                    A      Insurance companies rated in this category offer good
                           financial security. However, elements may be present
                           which suggest a susceptibility to impairment sometime
                           in the future.

S&P

S&P's credit rating is a current opinion of the creditworthiness of an obligor
with respect to a specific financial obligation, a specific class of financial
obligations, or a specific financial program.

                  AAA      This is the highest rating assigned by S&P. The
                           obligor's capacity to meet its financial commitment
                           on the obligation is extremely strong.

                   AA      The obligor's capacity to meet its financial
                           commitments on the obligation is very strong.

                    A      An obligation rated A is somewhat more susceptible to
                           the adverse effects of changes in circumstances and
                           economic conditions than obligations in higher rated
                           categories. However, the obligor's capacity to meet
                           its financial commitment on the obligation is still
                           strong.


SHORT-TERM DEBT RATINGS

Thompson Bank Watch, Inc. ("TBW") assigns ratings to specific debt instruments
with original maturities of one year or less. The TBW Short-Term ratings
specifically assess the likelihood of an untimely payment of principal and
interest.

                TBW-1      Very high degree of likelihood that principal and
                           interest will be paid on a timely basis.

                TBW-2      While degree of safety regarding timely repayment of
                           principal and interest is strong, the relative degree
                           is not as high as for issues rated TBW-1.

                TBW-3      Lowest investment grade category. While more
                           susceptible to adverse developments than obligations
                           with higher ratings, capacity to service principal
                           and interest in a timely fashion is considered
                           adequate.

                TBW-4      Non-investment grade and, therefore, speculative.

A BRIEF PREVIEW OF THE FUND

WHAT ARE THE GOALS OF ONE GROUP REAL ESTATE FUND?

The Fund is designed to provide current income and long-term growth of capital.

WHAT IS THE FUND'S INVESTMENT STRATEGY?

The Fund normally will invest in equity securities of companies operating in the
real estate industry. The Fund also may invest in debt securities and preferred
stocks which are convertible into common stock, and lend its portfolio
securities.

WHAT ARE THE MAIN RISKS OF INVESTING IN THE FUND?

Equity securities such as those in which the Fund may invest are more volatile
and carry more risk than some other forms of investment. Accordingly, as with
all equity investments, you may lose money by investing in the Fund. The Fund
may invest in derivative securities. These securities may expose the Fund to
special risks. Economic developments affecting the real estate industry will
have a disproportionate impact on the Fund. An investment in the Fund is not a
deposit of Bank One Corporation or its affiliates and is not insured or 
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency. For more information about risks, please read "More About the Fund" and
"Investment Risks."

WHAT CLASSES OF SHARES ARE AVAILABLE?

The Fund currently offers four classes of Shares: Class A, Class B, Class C and
Class I. Class A, Class B and Class C shares are offered to the general public.
Class I shares are offered to institutional investors, including affiliates of
Bank One Corporation and any bank, depository institution, insurance company,
pension plan or other organization authorized to act in fiduciary, advisory,
agency, custodial or similar capacities. The section called "How To Do Business
With One Group Mutual Funds" will provide more information. Class I shares are
not available to Individual Retirement Accounts ("IRA").

HOW DO I PURCHASE AND REDEEM SHARES?

You may buy and redeem shares of the Fund on any day that the Fund is open for
business. Purchase and redemption procedures are explained in greater detail in
"How To Do Business With One Group Mutual Funds." For additional information,
call The One Group Services Company at 1-800-480-4111 or visit One Group Mutual
Fund's web site at www.onegroup.com.

HOW ARE DIVIDENDS PAID?

Generally, dividends are declared on the last business day of each quarter and
are distributed periodically on the first business day of each quarter. Any
capital gains are distributed at least annually. Distributions are paid in
additional shares of the same class unless you elect to take the payment in
cash. For a more detailed discussion of dividends, see "Dividend Policies."

WHO MANAGES THE FUND?

Banc One Investment Advisors Corporation ("Banc One Investment Advisors"), an
indirect subsidiary of Bank One Corporation, serves as the advisor of the Fund.
A more detailed discussion regarding Banc One Investment Advisors, its services
and compensation can be found in the Prospectus under the headings "The Advisor"
and "Shareholder Expenses."

ONE GROUP(R) REAL ESTATE FUND

INVESTMENT OBJECTIVE

The Fund seeks to provide current income and long-term growth of capital.

PRINCIPAL INVESTMENT STRATEGY

The Fund invests primarily in equity securities of companies operating in the
real estate industry. "Real estate companies" are companies that earn at least
50% of their revenues from the ownership, construction, financing, management,
or sale of commercial, industrial, or residential real estate, or that have at
least 50% of their assets in real estate. These companies include real estate
investment trusts that either own properties or make construction or mortgage
loans, real estate developers, homebuilders, and companies with substantial real
estate holdings. The Fund also may invest in companies whose products and
services are related to the real estate industry, such as building supply
manufacturers, mortgage lenders, or mortgage servicing companies.

PORTFOLIO SECURITIES

The Fund normally invests at least 65% of its total assets in equity securities
of companies operating in the real estate industry. These securities include
common stocks, debt securities, and preferred stocks that are convertible to
common stocks. Up to 35% of the Fund's total assets may be invested in U.S.
government securities, other investment grade fixed income securities, cash and
cash equivalents. The Fund also may invest in the securities of foreign issuers.
For a list of all the securities in which the Fund may invest, please read
"Investment Practices."

RISK CONSIDERATIONS

The Fund invests in equity securities, which may increase or decrease in value.
As a result, the value of your investment in the Fund may increase or decrease
in value. The Fund also will invest in fixed income securities. The value of
these securities will change in response to interest rate changes and other
factors. This is especially true to the extent that the Fund invests in debt
securities in the lowest investment grade category. Such securities have
speculative characteristics. Because of its exposure to the real estate
industry, economic developments affecting that industry will have a
disproportionate impact on the Fund. Before you invest, please read "More About
the Fund" and "Investment Practices."

FUND MANAGEMENT

The Fund is managed by a team of portfolio managers, research analysts, and
other investment management professionals. Each team member makes
recommendations about the securities in the Fund. The research analysts provide
in-depth industry analysis and recommendations, while the portfolio managers
determine strategy, industry weightings, Fund holdings, and cash positions.

(1)      If you buy or sell shares through a Shareholder Servicing Agent, you
         may be charged separate transaction fees by the Shareholder Servicing
         Agent. In addition, a $10.00 sub-minimum account fee may be applicable
         and a $7.00 charge will be deducted from the redemption amounts paid by
         wire.

(2)      Except for purchases of $1 million or more. Please see "Sales Charges."

(3)      Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders
         may pay more than the equivalent of the maximum front-end sales charges
         permitted by the rules of the National Association of Securities
         Dealers. Without the voluntary waiver, 12b-1 fees would be .35% for
         Class A shares.

(4)      Total Operating Expenses have been revised to reflect fee waivers.
         Without the voluntary reduction of 12b-1 fees, Total Operating Expenses
         would be 1.45% for Class A shares.

MORE ABOUT THE FUND

PORTFOLIO QUALITY

The Fund only purchases securities that meet certain rating criteria.

o        Corporate bonds generally will be rated in one of the three highest
         investment grade categories.

o        Banc One Investment Advisors reserves the right to invest in corporate
         bonds which present attractive opportunities and are rated in the
         lowest investment grade category. These corporate bonds may be riskier
         than higher rated bonds.

If the securities are unrated, Banc One Investment Advisors must determine that
they are of comparable quality to rated securities. Banc One Investment Advisors
will look at a security's rating at the time of investment. For more information
about ratings, please see "Description of Ratings" in the Appendix.

ILLIQUID INVESTMENTS

The Fund may invest up to 15% of its net assets in illiquid investments. A
security is illiquid if it cannot be sold at approximately the value assessed by
the Fund within seven (7) days. Banc One Investment Advisors will follow
guidelines adopted by the One Group Board of Trustees in determining whether an
investment is illiquid.

SPECIAL RISK CONSIDERATIONS

REAL ESTATE SECURITIES: The Fund generally is subject to the same risks that
affect direct investments in real estate and its performance is closely tied to
conditions affecting the real estate industry. Real estate values rise and fall
in response to a variety of factors, including local, regional and national
economic conditions, the strength of specific industries renting properties, and
other factors affecting supply and demand for properties. When economic growth
is slowing, demand for property decreases and prices may decline. Rising
interest rates, which drive up mortgage and financing costs, can restrain
construction and buying and selling activity and make other investments more
attractive. Property values could decrease because of overbuilding, extended
vacancies, increase in property taxes and operating expenses, changes in zoning
laws, environmental regulations, clean-up of and liability for environmental
hazards, uninsured casualty or condemnation losses, or a general decline in
neighborhood values. The value of securities of companies that service the real
estate industry will also be affected by changes affecting the real estate
market.

DERIVATIVES: The Fund may invest in securities that are considered to be
"derivatives." Derivatives are securities or contracts that derive their value
from the performance of underlying assets or securities. These include:

o        options, futures contracts, and options on futures contracts

o        warrants

o        mortgage-backed securities, including collateralized mortgage
         obligations and Real Estate Mortgage Investment Conduits (CMOs and
         REMICs) and stripped mortgage-backed (Interest Only (IOs) and Principal
         Only (POs))

o        asset-backed securities

o        swap, cap and floor transactions

o        new financial products

These securities may be more volatile than other investments. Derivatives
present, to varying degrees, market, credit, leverage, liquidity, and management
risks. For a more detailed discussion of these risks, please read "Investment
Risks." A Fund's use of derivatives may cause the Fund to recognize higher
amounts of short-term capital gains (generally taxed at ordinary income tax
rates) than it would if the Fund did not use such instruments.


                                       9
<PAGE>   40
   
INTERNATIONAL INVESTMENTS: Investments in foreign securities involve risks
different from investments in U.S. securities. For more details, see "Investment
Practices" and "Investment Risks." Because of these risk factors, the share
price of a fund investing in foreign securities may be volatile, and you should
be able to sustain sudden, and sometimes substantial, fluctuations in the value
of your investment. On January 1, 1999, the European Economic and Monetary Union
introduced the "Euro." The Euro will serve as a common currency for
participating European nations. All stocks issued by corporations located in
those nations are denominated in Euros. In addition, outstanding shares have
been redenominated in Euros. All government bonds issued by participating
nations will be in Euros, and outstanding government bonds have been
redenominated in Euros. The introduction of the Euro presents some
uncertainties, such as the adequacy of newly created accounting, clearing,
settlement and payment systems for the new currency. These uncertainties
surrounding the introduction of the Euro could adversely affect the value of the
foreign securities held by the Fund.
    

SMALL CAPITALIZATION COMPANIES: Investments in smaller, younger companies may be
riskier than investments in larger, more established companies. These companies
may be more vulnerable to changes in economic conditions, specific industry
conditions, market fluctuations, and other factors affecting the profitability
of other companies. Because economic events may have a greater impact on smaller
companies, there may be a greater and more frequent fluctuation in their stock
price. This may cause frequent and unexpected increases or decreases in the
value of your investment.

FIXED INCOME SECURITIES: Investments in fixed income securities (for example,
bonds) will increase or decrease in value based on changes in interest rates. If
rates increase, the value of a Fund's investments generally declines. On the
other hand, if rates fall, the value of the investments generally increases. The
value of your investment in a Fund will increase and decrease as the value of a
Fund's investments increase and decrease. While securities with longer duration
and maturities tend to produce higher yields, they also are subject to greater
fluctuations in value when interest rates change. Usually changes in the value
of fixed income securities will not affect cash income generated, but may affect
the value of your investment. Fixed income securities also are subject to the
risk that the issuer of the security will be unable to meet its repayment
obligation.

NON-DIVERSIFIED FUND: The Fund is "non-diversified." This means that the Fund
may invest a more significant portion of its assets in the securities of a
single issuer than can a "diversified" fund. In addition, the Fund's investments
are concentrated in the real estate industry. This concentration increases the
risk of loss to the Fund by increasing its exposure to economic, business,
political or regulatory developments that may be adverse to the real estate
industry.

HOW TO DO BUSINESS WITH ONE GROUP MUTUAL FUNDS

PURCHASING FUND SHARES

WHERE CAN I BUY SHARES?

You may purchase Fund shares from the following sources:

o        The One Group Services Company, and

o        Shareholder Servicing Agents. These include investment advisors,
         brokers, financial planners, banks, insurance companies, retirement or
         401(k) plan sponsors, or other intermediaries. Shares purchased this
         way will be held for you by the Shareholder Servicing Agent.

WHEN CAN I BUY SHARES?

o        Purchases may be made on any business day. This includes any day that
         the Fund is open for business, other than weekends, days on which the
         New York Stock Exchange ("NYSE") is closed, and the following holidays:
         New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
         Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving, and
         Christmas.

o        Purchase requests received by The One Group Services Company before 4
         p.m. Eastern Time ("ET") will be effective that day. On occasion, the
         NYSE will close before 4 p.m. ET. When that happens, purchase requests
         received after the NYSE closes will be effective the following business
         day.

o        Purchase orders may be cancelled by the Fund's Custodian, State Street
         Bank and Trust Company, if it does not receive "federal funds" by 4:00
         p.m. ET (i) on the business day after the order is placed if you are
         buying Class I shares, and (ii) on the third business day if you are
         purchasing Class A, Class B or Class C shares.

o        If your shares are held by a Shareholder Servicing Agent, it is the
         responsibility of the Shareholder Servicing Agent to send your purchase
         or redemption order to the Fund. Your Shareholder Servicing Agent may
         have an earlier cut-off time for purchase and redemption requests.

o        The One Group Services Company can reject a purchase order if it does
         not think that it is in the best interests of a Fund and/or its
         shareholders to accept the order.

o        Shares are electronically recorded. Therefore, certificates will not be
         issued.

WHAT KIND OF SHARES CAN I BUY?

One Group offers the following classes of shares:

o        Class A, Class B and Class C shares are available to the general
         public.

o        Class I shares are available to institutional investors and any
         organization authorized to act in a fiduciary, advisory, custodial or
         agency capacity. We will refer to these entities as "Intermediaries."

o        If you intend to hold your shares for six or more years, Class B shares
         may be more appropriate for you. If you intend to hold your shares for
         less than six years, you may want to consider Class A or Class C
         shares.

One Group Fund Direct IRA. One Group offers a retirement plan. This plan allows
participants to defer taxes while their retirement savings grow. Call The One
Group Services Company at 1-800-480-4111 for an Adoption Agreement.

HOW MUCH DO SHARES COST?

o        Shares are sold at net asset value ("NAV") plus a sales charge, if any.

o        Each class of shares in each Fund has a different NAV. This is
         primarily because each class has different distribution expenses.

o        NAV per share is calculated by dividing the total market value of a
         Fund's investments and other assets allocable to a class (minus class
         expenses) by the number of outstanding shares in that class.

o        A Fund's NAV changes every day. NAV is calculated each business day
         following the close of the NYSE at 4:00 p.m. ET. On occasion, the NYSE
         will close before 4 p.m. ET. When that happens, NAV will be calculated
         as of the time the NYSE closes.

HOW DO I OPEN AN ACCOUNT?

1.       Read the prospectus carefully.

2.       Decide how much you want to invest.

         o        The minimum initial investment is $1,000 ($100 for employees
                  of Bank One Corporation and its affiliates). The minimum
                  initial investment for an IRA is $250.

         o        Subsequent investments must be at least $100 ($25 for
                  employees of Bank One Corporation and its affiliates).

         o        You may purchase no more than $250,000 of Class B shares at
                  one time.

         o        The One Group Services Company may waive these minimums.

3.       Complete the Account Application Form. Be sure to sign up for all of
         the Account privileges that you plan to take advantage of. Doing so now
         means that you will not have to complete additional paperwork later.

4.       Send the completed application and a personal check (unless you choose
         to pay by wire or bank transfer) payable to "One Group" to:

         State Street Bank and Trust Company
         c/o One Group
         P.O. Box 8528
         Boston, MA 02266-8528

         Contributions to Fund Direct IRAs should be made payable to "State
         Street Bank and Trust Company for the Benefit of (your name)."

5.       All checks should be in U.S. dollars. Third party checks will not be
         accepted. Redemptions from a Fund will not be permitted for ten (10)
         calendar days if purchases are made by check or under the Systematic
         Investment Plan (see below).

6.       If you purchase shares through a Shareholder Servicing Agent, you may
         be required to complete additional forms or follow additional
         procedures. You should contact your Shareholder Servicing Agent
         regarding purchases, exchanges and redemptions.

7.       If you have any questions, contact your Shareholder Servicing Agent or
         call The One Group Services Company at 1-800-480-4111.

CAN I PURCHASE SHARES OVER THE TELEPHONE?

Yes. Simply select this option on your Account Application Form and then:

o        Contact your Shareholder Servicing Agent or The One Group Services
         Company at 1-800-480-4111 to relay your purchase instructions.

o        Send a personal check made payable to "One Group" to State Street Bank
         and Trust Company (see address above), authorize a bank transfer, or
         initiate a wire transfer to the following wire address:

         State Street Bank and Trust Company
         Attn: Custody & Shareholder Services
         ABA 011 000 028
         DDA 99034167
         FBO One Group Fund (ex: One Group Real Estate--A)
         Your Account Number (ex: 123456789)
         Your Account Registration (ex: John Smith & Mary Smith, JTWROS)

o        One Group uses reasonable procedures to confirm that instructions given
         by telephone are genuine. These procedures include recording telephone
         instructions and asking for personal identification. If these
         procedures are followed, One Group will not be responsible for any
         loss, liability, cost or expense of acting upon unauthorized or
         fraudulent instructions; you bear the risk of loss.

o        You may revoke your right to make purchases over the telephone by
         sending a letter to:

         State Street Bank and Trust Company
         c/o One Group
         P.O. Box 8528
         Boston, MA 02266-8528

CAN I AUTOMATICALLY INVEST ON A SYSTEMATIC BASIS?

Yes. After your Account is established, you may purchase additional Class A,
Class B and Class C shares by making automatic monthly investments from your
bank account. The minimum initial investment is still $1,000, but minimum
automatic additions are only $25. The One Group Services Company may waive these
minimums. To establish a Systematic Investment Plan:

o        Select the "Systematic Investment Plan" option on the Account
         Application Form.

o        Provide the necessary information about the bank account from which
         your investments will be made.

o        Shares purchased under a Systematic Investment Plan may not be redeemed
         for ten (10) calendar days.

o        One Group currently does not charge for this service, but may impose a
         charge in the future. However, your bank may impose a charge for
         debiting your bank account.

o        You may revoke your right to make systematic investments by calling The
         One Group Services Company at 1-800-480-4111 or by sending a letter to:

         State Street Bank and Trust Company
         c/o One Group
         P.O. Box 8528
         Boston, MA 02266-8528


CONVERSION FEATURE

Your Class B shares automatically convert to Class A shares after eight years
(measured from the end of the month in which they were purchased).


                                       13
<PAGE>   44


o        After conversion, your shares will be subject to the lower distribution
         and shareholder servicing fees charged on Class A shares.

o        You will not be assessed any sales charges or fees for conversion of
         shares, nor will you be subject to any Federal income tax.

o        Because the share price of the Class A shares may be higher than that
         of the Class B shares at the time of conversion, you may receive fewer
         Class A shares; however, the dollar value will be the same.

o        If you have exchanged Class B shares of one Fund for Class B shares of
         another, the time you held the shares in each Fund will be added
         together.

SALES CHARGES

The One Group Services Company compensates Shareholder Servicing Agents who sell
shares of One Group. Compensation comes from sales charges, 12b-1 fees and
payments by The One Group Services Company from its own resources. Occasionally,
The One Group Services Company, at its own expense, also will provide cash
incentives which will be paid to select Shareholder Servicing Agents. Those
Shareholder Servicing Agents who may receive special incentives include Banc One
Securities Corporation, The Advisors Group, United Planners Financial Services
of America, Inc., The Legend Group, and Rosewood Retirement Advisory Services,
LLC. The One Group Services Company pays additional compensation to Shareholder
Servicing Agents for sales of over $1 million dollars of Class A shares.
Shareholder Servicing Agents receive 1.00% of the purchase price of Class A
shares for sales of $1 million to $5 million, and 0.50% on amounts over $5
million.

         the Class A shares within one year of purchase and 0.50% of the
         purchase price if you redeem within two years of purchase, unless The
         One Group Services Company receives notice before you invest indicating
         that your Shareholder Servicing Agent is waiving its commission.

</TABLE>

Shareholder Servicing Agents selling Class C shares receive a commission of
1.00% of the original purchase price from The One Group Services Company.

How the CDSC is Calculated

o        The Fund assumes that all purchases made in a given month were made on
         the first day of the month.

o        The CDSC is based on the current market value or the original cost of
         the shares, whichever is less.

o        A sales charge is not imposed on increases in NAV above the initial
         purchase price, nor is a sales charge assessed on shares acquired
         through reinvestment of dividends or capital gains distributions.

o        To keep your CDSC as low as possible, the Fund first will redeem any
         shares in your account that carry no CDSC, starting with Class A
         Shares. After that, the Fund will redeem the shares you have held for
         the longest time and thus have the lowest CDSC.

o        If you exchange Class B or Class C shares of an unrelated mutual fund
         for Class B or Class C shares of One Group in connection with a fund
         reorganization, the CDSC applicable to your original shares (including
         the period of time you have held those shares) will be applied to One
         Group shares you receive in the reorganization.

12b-1 FEES

12b-1 fees are paid by One Group to The One Group Services Company as
compensation for its services and expenses. The One Group Services Company in
turn pays all or part of the 12b-1 fee to Shareholder Servicing Agents that sell
shares of One Group.

o        The 12b-1 fees vary by share class as follows:

         1.       Class A shares pay a 12b-1 fee of .35% of the average daily
                  net assets of the Fund, which is currently being waived to
                  .25%.

         2.       Class B and Class C shares pay a 12b-1 fee of 1.00% of the
                  average daily net assets of the Fund. This will cause expenses
                  for Class B and Class C shares to be higher and dividends to
                  be lower than for Class A shares.

         3.       There are no 12b-1 fees for Class I shares.

o        12b-1 fees, together with the CDSC, help The One Group Services Company
         sell Class B and Class C shares without an "up-front" sales charge by
         financing the costs of advancing brokerage commissions and other
         expenses paid to Shareholder Servicing Agents.

         o        The One Group Services Company may use up to .25% of the fees
                  for shareholder servicing and up to .75% for distribution.
                  During the last fiscal year, The One Group Services Company
                  received 12b-1 fees totaling .25% and 1.00% of the average
                  daily net assets of Class A and Class B shares, respectively.

         o        The One Group Services Company may pay 12b-1 fees to its
                  affiliates and to Banc One Investment Advisors and its

SALES CHARGE REDUCTIONS AND WAIVERS

REDUCING YOUR CLASS A SALES CHARGES

There are several ways you can reduce the sales charges you pay on Class A
shares:

1.       Right of Accumulation: You may add the market value of any Class A,
         Class B or Class C shares of a Fund (except a money market fund) that
         you (and your spouse and minor children) already own to the amount of
         your next Class A purchase for purposes of calculating the sales
         charge. An Intermediary also may take advantage of this option.

2.       Letter of Intent: With an initial investment of $2,000, you may
         purchase Class A shares of one or more funds over the next 13 months
         and pay the same sales charge that you would have paid if all shares
         were purchased at once. A percentage of your investment will be held in
         escrow until the full amount covered by the Letter of Intent has been
         invested.

To take advantage of the accumulation privilege or letter of intent, complete
the appropriate section of your fund application, or contact your investment
representative. To determine if you are eligible for the accumulation privilege,
contact The One Group Services Company at 1-800-480-4111. These programs may be
terminated or amended at any time.

EXCHANGING FUND SHARES

WHAT ARE MY EXCHANGE PRIVILEGES?

You may make the following exchanges:

o        Class I shares of a Fund may be exchanged for Class A shares of that
         Fund or for Class A or Class I shares of another One Group Fund.

o        Class A shares of a Fund may be exchanged for Class I shares of that
         Fund or for Class A or Class I shares of another One Group Fund, but
         only if you are eligible to purchase those shares.

o        Class B shares of a Fund may be exchanged for Class B shares of another
         One Group Fund.

o        Class C shares of a Fund may be exchanged for Class C shares of another
         One Group Fund.

One Group Funds offer a Systematic Exchange Privilege which allows you to
automatically exchange shares of one fund to another on a monthly or quarterly
basis. This privilege is useful in Dollar Cost Averaging. To participate in this
privilege, please select it on your account application. To learn more about it,
please call The One Group Services Company at 1-800-480-4111.

One Group does not charge a fee for this privilege. In addition, One Group may
change the terms and conditions of your exchange privileges upon 60 days written
notice.

WHEN ARE EXCHANGES PROCESSED?

Exchanges are processed the same business day they are received, provided:

o        State Street Bank and Trust Company receives the request by 4:00 p.m.,
         ET.

o        You have provided One Group with all of the information necessary to
         process the exchange.

o        You have received a current prospectus of the Fund or Funds in which
         you wish to invest.

o        You have contacted your Shareholder Servicing Agent, if necessary.

DO I PAY A SALES CHARGE ON AN EXCHANGE?

Generally, you will not pay a sales charge on an exchange. However:

o        You will pay a sales charge if you own Class I shares of a Fund and you
         want to exchange those shares for Class A shares, unless you qualify
         for a sales charge waiver (see above).

o        You will pay a sales charge if you bought Class A shares of a Fund:

1.       That does not charge a sales charge and you want to exchange them for
         shares of a Fund that does, in which case you would pay the sales
         charge applicable to the Fund into which you are exchanging.

2.       That charged a lower sales charge than the Fund into which you are
         exchanging, in which case you would pay the difference between that
         Fund's sales charge and all other sales charges you have already paid.

o        If you exchange Class B or Class C shares of a Fund, you will not pay a
         sales charge at the time of the exchange, however:

1.       Your new Class B or Class C shares will be subject to the higher CDSC
         of either the Fund from which you exchanged, the Fund into which you
         exchanged, or any Fund from which you previously exchanged.

2.       The current holding period for your exchanged Class B or Class C shares
         is carried over to your new shares.


                                       19
<PAGE>   50


ARE EXCHANGES TAXABLE?

Generally:

o        An exchange between classes of shares of the same Fund is not taxable
         for Federal income tax purposes.

o        An exchange between Funds is considered a sale and generally results in
         a capital gain or loss for Federal income tax purposes.

o        You should talk to your tax advisor before making an exchange.

ARE THERE LIMITS ON EXCHANGES?

Yes. The exchange privilege is not intended as a way for you to speculate on
short term movements in the market. Therefore:

o        To prevent disruptions in the management of the Funds, One Group limits
         excessive exchange activity.

o        Exchange activity is excessive if it EXCEEDS TWO SUBSTANTIVE EXCHANGE
         REDEMPTIONS (WITHIN 30 DAYS OF EACH OTHER) WITHIN A TWELVE MONTH
         PERIOD.

o        In addition, One Group reserves the right to reject any exchange
         request (even those that are not excessive) if the Fund reasonably
         believes that the exchange will result in excessive transaction costs
         or otherwise adversely affect other shareholders.

REDEEMING FUND SHARES

WHEN CAN I REDEEM SHARES?

You may redeem all or some of your shares on any day that the Fund is open for
business.

<PAGE>   51


         4.       the redemption is payable by wire or bank transfer (ACH) to a

         proceeds mailed or wired to:

                  Servicing Agent.

o        State Street Bank and Trust Company may charge you a wire redemption
         fee. The current charge is $7.00.

o        Your redemption proceeds will be paid within seven days after receipt
         of the redemption request.

WHAT WILL MY SHARES BE WORTH?

o        If you own Class A and Class I shares and the Fund receives your
         redemption request by 4:00 p.m. ET (or when the NYSE closes), you will
         receive that day's NAV.

o        If you own Class B or Class C shares and the Fund receives your
         redemption request by 4:00 p.m. ET (or when the NYSE closes), you will
         receive that day's NAV, minus the amount of any applicable CDSC.

CAN I REDEEM BY TELEPHONE?

Yes, if you selected this option on your Account Application Form.

o        Call your Shareholder Servicing Agent or The One Group Service Company
         at 1-800-480-4111 to relay your redemption request.

o        Your redemption proceeds will be mailed or wired to the commercial bank
         account you designated on your Account Application Form.

o        State Street Bank and Trust Company may charge you a wire redemption
         fee. The current charge is $7.00.

o        One Group uses reasonable procedures to confirm that instructions given
         by telephone are genuine. These procedures include recording telephone
         instructions and asking for personal identification. If these
         procedures are followed, One Group will not be responsible for any
         loss, liability, cost or expense of acting upon unauthorized or
         fraudulent instructions; you bear the risk of loss.

o        REDEMPTIONS FROM YOUR IRA ACCOUNT MAY NOT BE MADE BY TELEPHONE.

CAN I REDEEM ON A SYSTEMATIC BASIS?

If you have an account value of at least $10,000, you may elect to receive

o        Select the "Systematic Withdrawal Plan" option on the Account
         Application Form.

o        Specify the amount you wish to receive and the frequency of the
         payments.

o        You may designate a person other than yourself as the payee.

o        There is no charge for this service.

o        If you select this option, please keep in mind that:

         1.       It may not be in your best interest to buy additional Class A
                  shares while participating in a Systematic Withdrawal Plan.
                  This is because Class A shares have an up-front sales charge.


                                       21
<PAGE>   52


         2.       If you own Class B or Class C shares, you or your designated
                  payee may receive systematic payments provided the payments
                  are limited to no more than 10% of your account value
                  annually, measured from the date the redemption request is
                  received.

         3.       If you are age 70-1/2, you may elect to receive payments to
                  the extent that the payment represents a minimum required
                  distribution from an IRA or other qualifying retirement plan.

         4.       If the amount of the systematic payment exceeds the income
                  earned by your account since the previous payment under the
                  Systematic Withdrawal Plan, payments will be made by redeeming
                  some of your shares. This will reduce the amount of your
                  investment.

ADDITIONAL INFORMATION REGARDING REDEMPTIONS

o        All redemptions will be for cash.

o        If you redeem shares for which you paid by check, and One Group has not
         yet received payment on the check, One Group will delay forwarding your
         redemption proceeds for 10 or more days until payment has been
         collected from your bank.

o        Because of the high cost of handling small investments, One Group
         charges a sub-minimum account fee. Accounts under $1,000 that are not
         participating in a Systematic Investment Plan will be assessed an
         annual fee of $10.00. The sub-minimum account fee will not apply to IRA
         accounts and the accounts of employees of Bank One Corporation and its
         affiliates.

o        One Group may suspend your ability to redeem when:

         1.       Trading on the New York Stock Exchange ("NYSE") is restricted.

         2.       The NYSE is closed (other than weekend and holiday closings).

         3.       The SEC has permitted a suspension.

         4.       An emergency exists.

         The Statement of Additional Information offers more details about this 
         process.

o        You generally will recognize a gain or loss on a redemption for Federal
         income tax purposes. You should talk to your tax advisor before making
         a redemption.

SHAREHOLDER INFORMATION

VOTING RIGHTS

The Fund does not hold annual shareholder meetings, but may hold special
meetings. The special meetings are held, for example, to elect or remove
Trustees, change the Fund's fundamental investment objective, or approve an
investment advisory contract.

As a Fund shareholder, you have one vote for each share that you own. Each Fund,
and each class of shares within each Fund, vote separately on matters relating
solely to that Fund or class, or which affect that Fund or class differently.
However, all shareholders will have equal voting rights on matters that affect
all shareholders equally.

DIVIDEND POLICIES

DIVIDENDS

The Fund generally declares dividends on the last business day of each quarter.
Dividends are distributed on the first business day of the next quarter. Capital
gains, if any, for the Fund are distributed at least annually.

The Fund pays dividends and distributions on a per-share basis. This means that
the value of your shares will be reduced by the amount of the payment. If you
purchase shares shortly before the record date for a dividend or the
distribution of capital gains, you will pay the full price for the shares and
receive some portion of the price back as a taxable dividend or distribution.

Dividends payable on Class I shares will be more than those payable on other
classes of shares. This is because Class A, Class B and Class C shares have
higher distribution expenses.

DIVIDEND REINVESTMENT

You automatically will receive all income dividends and capital gain
distributions in additional shares of the same Fund and class, unless you have
elected to take such payment in cash. The price of the shares is the NAV
determined immediately following the dividend record date. Reinvested dividends
and distributions receive the same tax treatment as dividends and distributions
paid in cash.

If you want to change the way in which you receive dividends and distributions,
you must write to State Street Bank & Trust Company at P.O. Box 8528, Boston, MA
02266-8528, at least 15 days prior to the distribution. The change is effective
upon receipt by State Street. You also may change the way you receive dividends
and distributions by calling The One Group Services Company at 1-800-480-4111.

SPECIAL DIVIDEND RULES FOR CLASS B SHARES

Class B shares received as dividends and capital gains distributions will be
accounted for separately. Each time any Class B shares (other than those in the
sub-account) convert to Class A shares, a percentage of the Class B shares in
the sub-account will also convert to Class A shares. (See "Conversion Feature.")

TAX TREATMENT OF THE FUND

TAX STATUS OF THE FUND

The Fund intends to qualify as a "regulated investment company" for Federal
income tax purposes. If the Fund qualifies, as it has in the past, it will pay
no federal income tax on the earnings it distributes to shareholders.




                                       23
<PAGE>   54


TAX TREATMENT OF SHAREHOLDERS

TAXATION OF SHAREHOLDER TRANSACTIONS

A sale, exchange, or redemption of Fund shares generally will produce either a
taxable gain or a loss. You are responsible for any tax liabilities generated by
your transactions.


TAXATION OF DISTRIBUTIONS

The Fund will distribute substantially all of its net investment income
(including, for this purpose, the excess of net short-term capital gains over
net long-term capital losses and net capital gains (i.e., the excess of net
long-term capital gains over net short-term capital losses) on at least an
annual basis. Dividends you receive from the Fund, whether reinvested or
received in cash, will be taxable to you. Dividends from a Fund's net investment
income will be taxable as ordinary income and distributions from the Fund's
long-term capital gains will be taxable to you as such, regardless of how long
you have held the shares. Distributions are taxable to you even if they are paid
from income or gains earned by the Fund prior to your investment (and thus were
included in the price you paid).

Dividends paid in January, but declared in October, November or December of the
previous year, will be considered to have been paid in the previous year.

TAXATION OF RETIREMENT PLANS

Distributions by the Fund to qualified retirement plans generally will not be
taxable. However, if shares are held by a plan that ceases to qualify for
tax-exempt treatment or by an individual who has received shares as a
distribution from a retirement plan, the distributions will be taxable to the
plan or individual as described in "Taxation of Distributions." If you are
considering purchasing shares with qualified retirement plan assets, you should
consult your tax advisor for a more complete explanation of the Federal, state,
local and (if applicable) foreign tax consequences of making such an investment.

TAX INFORMATION

The Form 1099 that is mailed to you every January details your dividends and
their federal tax category. Even though the Fund provides you with this
information, you are responsible for verifying your tax liability with your tax
professional. For additional tax information see the Statement of Additional
Information. Please note that this tax discussion is general in nature; no
attempt has been made to present a complete explanation of the Federal, state,
local or foreign tax treatment of the Fund or their shareholders.

ORGANIZATION AND MANAGEMENT OF THE FUND

THE FUND

The Fund is a series of One Group Mutual Funds, an open-end management
investment company. One Group currently offers 53 separate Funds. The other
Funds are described in separate prospectuses. The Fund described in this
prospectus is non-diversified. Each Fund of One Group Mutual Funds is supervised
by the Board of Trustees.

THE BOARD OF TRUSTEES

The Trustees oversee the management and administration of the Fund. The Trustees
are responsible for making major decisions about the Fund's investment
objectives and policies, but delegate the day-to-day administration of the Fund
to the officers of One Group.

THE ADVISOR

Banc One Investment Advisors makes the day-to-day investment decisions for the
Fund and continuously reviews, supervises and administers the Fund's investment
programs. Banc One Investment Advisors has served as investment advisor to One
Group since 1993. Prior to that time, One Group was advised by affiliates of
Banc One Investment Advisors. In addition to One Group, Banc One Investment
Advisors serves as investment advisor to other mutual funds and individual,
corporate, charitable and retirement accounts. As of March 29, 1999, Banc One
Investment Advisors, an indirect, wholly-owned subsidiary of Bank One
Corporation, managed over $120 billion in assets.

Fund's average daily net assets. The annual rate declines to .18% on assets up
to $2 billion, and to .16% when assets exceed $2 billion. The fee is calculated

YEAR 2000

Preparing for the Year 2000 is a high priority for One Group. Both The One Group
Services Company and Banc One Investment Advisors have formed dedicated teams to
help them successfully achieve Year 2000 compliance. In addition, these teams
are responsible for assessing the readiness of all other service providers to
One Group. Year 2000 remediation efforts are directed toward both information
technology and non-information technology systems. Non-information technology
systems include elevators, photocopy machines, and facsimile machines, and
should have no significant impact on the delivery of services to One Group.

Banc One Investment Advisors has identified 49 information technology systems
and interfaces that provide service and support to One Group. Each system is
assigned a priority rating: high, medium or low. Systems rated "high" are those
which are essential to the operation of One Group. Each system rated "high" was
scheduled to be Year 2000 compliant by December 31, 1998. All systems will be
tested for compliance throughout 1999.

Many, if not all, of the systems are owned or operated by third party servicers
(for example, One Group's Custodian). Consequently, remediation efforts must be
made by those servicers. Banc One Investment Advisors and The One Group Services
Company have, and will continue to, monitor the remediation progress of the
service providers. This process involves documentation, on-site visits, and
review of remediation plans and test results. Both Banc One Investment Advisors
and The One Group Services Company have budgeted in excess of $700,000 in fiscal
year 1998 and over $1 million in fiscal year 1999 toward the remediation effort
for all systems and interfaces. Neither One Group nor its shareholders will bear
any of the direct remediation expenses.

Neither The One Group Services Company nor Banc One Investment Advisors
currently anticipates that the move to Year 2000 will have a material impact on
their ability to continue to provide the Fund with service at current levels.
Likewise, One Group currently anticipates that the move to Year 2000 will not
have a material impact on its operations.

INVESTMENT RISKS

Below is a more complete discussion of the types of risks inherent in the
securities and investment techniques listed above. Because of these risks, the
value of the securities held by the Fund may fluctuate, as will the value of
your investment in the Fund. Certain investments are more susceptible to these
risk than others.

o        CREDIT RISK. The risk that the issuer of a security, or the
         counterparty to a contract, will default or otherwise become unable to
         honor a financial obligation. Credit risk is generally higher for
         non-investment grade securities. The price and liquidity of a security
         can be adversely affected prior to actual default as its credit status
         deteriorates and the probability of default rises.

o        LEVERAGE RISK. The risk associated with securities or practices that
         multiply small index or market movements into large changes in value.
         Leverage is often associated with investments in derivatives, but also
         may be embedded directly.

         o        HEDGED. When a derivative (a security whose value is based on 
         another security or index) is used as a hedge against an opposite
         position that the fund also holds, any loss generated by the derivative
         should be substantially offset by gains on the hedged investment, and
         vice versa. While hedging can reduce or eliminate losses, it can also
         reduce or eliminate gains. Hedges are sometimes subject to imperfect
         matching between the derivative and underlying security, and there can
         be no assurance that a Fund's hedging transactions will be effective.

         o        SPECULATIVE. To the extent that a derivative is not used as a 
         hedge, the fund is directly exposed to the risks of that derivative.
         Gains or losses from speculative positions in a derivative may be
         substantially greater than the derivative's original cost.

o        LIQUIDITY RISK. The risk that certain securities may be difficult or
         impossible to sell at the time and the price that would normally
         prevail in the market. The seller may have to lower the price, sell
         other securities instead or forego an investment opportunity, any of
         which could have a negative effect on fund management or performance.
         This includes the risk of missing out on an investment opportunity
         because the assets necessary to take advantage of it are tied up in
         less advantageous investments.

o        MANAGEMENT RISK. The risk that a strategy used by a fund's management
         may fail to produce the intended result. This includes the risk that
         changes in the value of a hedging instrument will not match those of
         the asset being hedged. Incomplete matching can result in unanticipated
         risks.

o        MARKET RISK. The risk that the market value of a security may move up
         and down, sometimes rapidly and unpredictably. These fluctuations may
         cause a security to be worth less than the price originally paid for
         it, or less than it was worth at an earlier time. Market risk may
         affect a single issuer, industry, sector of the economy or the market
         as a whole. There is also the risk that the current interest rate may
         not accurately reflect existing market rates. For fixed income
         securities, market risk is largely, but not exclusively, influenced by
         changes in interest rates. A rise in interest rates typically causes a
         fall in values, while a fall in rates typically causes a rise in
         values. Finally, key information about a security or market may be
         inaccurate or unavailable. This is particularly relevant to investments
         in foreign securities.

o        POLITICAL RISK. The risk of losses attributable to unfavorable
         governmental or political actions, seizure of foreign deposits, changes
         in tax or trade statutes, and governmental collapse and war.

o        FOREIGN INVESTMENT RISK. The risk associated with higher transaction
         costs, delayed settlements, currency controls and adverse economic
         developments. This also includes the risk that fluctuations in the
         exchange rates between the U.S. dollar and foreign currencies may
         negatively affect an investment. Adverse changes in exchange rates may
         erode or reverse any gains produced by foreign currency denominated
         investments and may widen any losses. Exchange rate volatility also my
         affect the ability of an issuer to repay U.S. dollar denominated debt,
         thereby increasing credit risk.

o        PRE-PAYMENT RISK. The risk that the principal repayment of a security
         will occur at an unexpected time, especially that the repayment of a
         mortgage or asset-backed security occurs either significantly sooner or
         later than expected. Changes in pre-payment rates can result in greater
         price and yield volatility. Pre-payments generally accelerate when
         interest rates decline. When mortgage 



                                       32
<PAGE>   63


         and other obligations are pre-paid, a Fund may have to reinvest in
         securities with a lower yield. Further, with early prepayment, a Fund
         may fail to recover any premium paid, resulting in an unexpected
         capital loss.

o        TAX RISK. The risk that the issuer of the securities will fail to
         comply with certain requirements of the Internal Revenue Code, which
         would cause adverse tax consequences.

o        REGULATORY RISK. The risk associated with Federal and state laws which
         may restrict the remedies that a lender has when a borrower defaults on
         loans. These laws include restrictions on foreclosures, redemption
         rights after foreclosure, Federal and state bankruptcy and debtor
         relief laws, restrictions on "due on sale" clauses, and state usury
         laws.

INVESTMENT POLICIES

The Fund's investment objective and the investment policies summarized below are
fundamental. This means that they cannot be changed without the consent of a
majority of the outstanding shares of the Fund. The full text of the fundamental
policies can be found in the Statement of Additional Information.

The Fund may not:

1.       Purchase an issuer's securities if as a result more than 25% of its
         total assets would be invested in the securities of that issuer. This
         restriction applies with respect to 50% of a Fund's total assets. With
         respect to the remaining 50% of the Fund's total assets, it may not
         purchase an issuer's securities if as a result more than 5% of its
         total assets would be invested in the securities of that issuer. This
         does not include securities issued or guaranteed by the United States,
         its agencies or instrumentalities, and repurchase agreements involving
         these securities.

2.       Concentrate its investments in the securities of one or more issuers
         conducting their principal business in a particular industry or group
         of industries (except the real estate industry). This does not include
         obligations issued or guaranteed by the U.S. government or its agencies
         and instrumentalities and repurchase agreements involving such
         securities.

3.       Make loans, except that a Fund may (i) purchase or hold debt
         instruments in accordance with its investment objective and policies;
         (ii) enter into repurchase agreements; and (iii) engage in securities
         lending.


Additional investment policies can be found in the Statement of Additional
Information.

TEMPORARY DEFENSIVE POSITION

Sometimes Banc One Investment Advisors decides that the Fund should temporarily
be invested up to 100% in cash and cash equivalents. Cash equivalents include:

o        Securities issued by the U.S. Government, its agencies and
         instrumentalities

o        Repurchase Agreements

o        Certificates of Deposit

o        Bankers' Acceptances

o        Commercial Paper (rated in one of the two highest rating categories)

o        Variable Rate Master Demand Notes

o        Bank Money Market Deposit Accounts

While the Fund is engaged in a temporary defensive position, it will not be
pursuing its investment objectives. Therefore, the Fund will pursue a temporary
defensive position only when market conditions warrant.

PORTFOLIO TURNOVER

Portfolio turnover may vary greatly from year to year, as well as within a
particular year.

Higher portfolio turnover rates will likely result in higher transaction costs
to the Fund and may result in additional tax consequences to you. The portfolio
turnover rate for the Fund is not expected to exceed 50%. To the extent
portfolio turn over results in short-term capital gains, such gains will
generally be taxed at ordinary income tax rates.

APPENDIX

DESCRIPTION OF RATINGS

The following is a summary of published ratings by major credit rating agencies.
Credit ratings evaluate only the safety of principal and interest payments, not
the market value risk of lower quality securities. Credit rating agencies may
fail to change credit ratings to reflect subsequent events on a timely basis.
Although Banc One Investment Advisors considers security ratings when making
investment decisions, it also performs its own investment analysis and does not
rely solely on the ratings assigned by credit agencies.

Unrated securities will be treated as non-investment grade securities unless
Banc One Investment Advisors determines that such securities are the equivalent
of investment grade securities. Securities that have received different ratings
from more than one agency are considered investment grade if at least one agency
has rated the security investment grade.

DESCRIPTION OF COMMERCIAL PAPER RATINGS

DUFF & PHELPS CREDIT RATING CO. ("DUFF")

         D-1+     Highest certainty of timely payment. Short-term liquidity,
                  including internal operating factors and/or access to
                  alternative sources of funds, is outstanding and safety is
                  just below risk-free U.S. Treasury obligations.

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

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

STANDARD & POOR'S CORPORATION ("S&P")

         A-1      Highest category of commercial paper. Capacity to meet
                  financial commitment is strong. Obligations designated with a
                  plus sign (+) indicate that capacity to meet financial
                  commitment is extremely strong.

         A-2      Issues somewhat more susceptible to adverse effects of changes
                  in circumstances and economic conditions than obligations in
                  higher rating categories. However, the capacity to meet
                  financial commitments is satisfactory.

FITCH'S IBCA INC. ("FITCH")

         F1       Highest capacity for timely repayment. Those issues rated F1+
                  possess a particularly strong credit feature.

         F2       Satisfactory capacity for timely repayment although such
                  capacity may be susceptible to adverse changes in business,
                  economic or financial conditions.

MOODY'S INVESTORS SERVICE ("MOODY'S")

PRIME-1  Superior ability for repayment.

PRIME-2  Strong ability for repayment.

DESCRIPTION OF BANK RATINGS

MOODY'S

These ratings represent Moody's opinion of a bank's intrinsic safety and
soundness.

<PAGE>   66


         A        These banks possess exceptional intrinsic financial strength.
                  Typically they will be major financial institutions with
                  highly valuable and defensible business franchises, strong
                  financial fundamentals, and a very attractive and stable
                  operating environment.

         B        These banks possess strong intrinsic financial strength.
                  Typically, they will be important institutions with valuable
                  and defensible business franchises, good financial
                  fundamentals, and an attractive and stable operating
                  environment.

         C        These banks possess good intrinsic financial strength.
                  Typically, they will be institutions with valuable and
                  defensible business franchises. These banks will demonstrate
                  either acceptable financial fundamentals within a stable
                  operating environment, or better than average financial
                  fundamentals within an unstable operating environment.

S&P

S&P's credit rating is a current opinion of an obligor's overall financial
capacity (its creditworthiness) to pay its financial obligation.

         Aaa      The highest rating assigned by S&P. The obligor's capacity to
                  meet its financial commitment on the obligation is extremely
                  strong.

         Aa       The obligor's capacity to meet its financial commitments on
                  the obligation is very strong.

         A        The obligation is somewhat more susceptible to the adverse
                  effects of changes in circumstances and economic conditions
                  than obligations in higher rated categories. However, the
                  obligor's capacity to meet its financial commitment on the
                  obligation is still strong.

DESCRIPTION OF INSURANCE RATINGS

MOODY'S

These ratings represent Moody's opinions of the ability of insurance companies
to pay punctually senior policyholder claims and obligations.

         Aaa      Insurance companies rated in this category offer exceptional
                  financial security. While the financial strength of these
                  companies is likely to change, such changes as can be
                  visualized are most unlikely to impair their fundamentally
                  strong position.

         Aa       These insurance companies offer excellent financial security.
                  Together with the Aaa group, they constitute what are
                  generally known as high grade companies. They are rated lower
                  than Aaa companies because long-term risks appear somewhat
                  larger.

         A        Insurance companies rated in this category offer good
                  financial security. However, elements may be present which
                  suggest a susceptibility to impairment sometime in the future.

S&P

S&P's credit rating is a current opinion of the creditworthiness of an obligor
with respect to a specific financial obligation, a specific class of financial
obligations, or a specific financial program.

         AAA      This is the highest rating assigned by S&P. The obligor's
                  capacity to meet its financial commitment on the obligation is
                  extremely strong.

         AA       The obligor's capacity to meet its financial commitments on
                  the obligation is very strong.

         A        An obligation rated A is somewhat more susceptible to the
                  adverse effects of changes in circumstances and economic
                  conditions than obligations in higher rated categories.
                  However, the obligor's capacity to meet its financial
                  commitment on the obligation is still strong.

DESCRIPTION OF CORPORATE BOND RATINGS

S&P

Investment Grade

         AAA      The highest rating. The rating indicates an extremely strong
                  capacity to meet its financial commitment.

         AA       Differs from AAA issues only in a small degree. The obligor's
                  capacity to meet its financial commitment is very strong.

         A        These bonds are somewhat more susceptible to the adverse
                  effects of changes in circumstances and economic conditions
                  than debt in higher rated categories. However, capacity to
                  meet its financial commitment on the obligation is still
                  strong.

         BBB      Exhibits adequate protection parameters. However, adverse
                  economic conditions or changing circumstances are more likely
                  to lead to a weakened capacity to meet its financial
                  commitment on the obligation.

Non-Investment Grade

         BB       Less vulnerable to non-payment than other speculative issues.
                  However, these bonds face major ongoing uncertainties or
                  exposure to adverse business, financial or economic conditions
                  which could lead to inadequate capacity to meet financial
                  commitment on the obligation.

         B        More vulnerable to non-payment than obligations rated BB, but
                  currently has the capacity to meet its financial commitment on
                  the obligation. Adverse business, financial or economic
                  conditions will likely impair capacity or willingness to meet
                  its financial commitment on the obligation.

         CCC      Currently vulnerable to non-payment, and is dependent upon
                  favorable business, financial, and economic conditions to meet
                  its financial commitment on the obligation. In the event of
                  adverse business, financial, or economic conditions, they are
                  not likely to have the capacity to meet its financial
                  commitment on the obligation.

         CC       Currently highly vulnerable to non-payment.

         C        This rating may be used to cover a situation where a
                  bankruptcy petition has been filed, or similar action has been
                  taken, but payments on this obligation are being continued.

         D        Bonds in payment default.

Ratings from AA to CCC may be modified by a plus (+) or minus (-) to show
relative standing within the major rating categories.

MOODY'S

Investment Grade

         Aaa      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 an exceptionally stable,
                  margin and principal is secure.

         Aa       High quality by all standards. Margins of protection may not
                  be as large as in Aaa securities, fluctuation of protective
                  elements may be greater, or there may be other elements
                  present that make the long-term risks appear somewhat larger
                  than in Aaa securities.

         A        These bonds possess many favorable investment attributes and
                  are to be considered as upper-medium grade obligations.
                  Factors giving security to principal and interest are
                  considered adequate, but elements may be present which suggest
                  a susceptibility to impairment sometime in the future.

         Baa      These bonds are considered 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.

Non-Investment Grade

         Ba       These bonds have speculative elements; their future cannot be
                  considered as well assured. The protection of interest and
                  principal payments may be very moderate and thereby not well
                  safeguarded during good and bad times over the future.

         B        These bonds lack the characteristics of a desirable investment
                  (i.e., potentially low assurance of timely interest and
                  principal payments or maintenance of other contract terms over
                  any long period of time may be small).

         Caa      Bonds in this category have poor standing and may be in
                  default. These bonds carry an element of danger with respect
                  to principal and interest payments.

         Ca       Speculative to a high degree and could be in default or have
                  other marked shortcomings. Ca is the lowest rating.


DESCRIPTION OF PREFERRED STOCK RATINGS

MOODY'S

         aaa      Top-quality preferred stock. This rating indicates good asset
                  protection and the least risk of dividend impairment within
                  the universe of preferred stocks.

         aa       High-grade preferred stock. This rating indicates that there
                  is a reasonable assurance the earnings and asset protection
                  will remain relatively well maintained in the foreseeable
                  future.

         a        Upper-medium grade preferred stock. While risks are judged to
                  be somewhat greater than in the "aaa" and "aa" classification,
                  earnings and asset protection are, nevertheless, expected to
                  be maintained at adequate levels.

         baa      Medium-grade preferred stock, neither highly protected nor
                  poorly secured. Earnings and asset protection appear adequate
                  at present but may be questionable over any great length of
                  time.

S&P

S&P's preferred stock rating is an assessment of the capacity and willingness of
an issuer to pay preferred stock dividends and any applicable sinking fund
obligations.

         AAA      Highest rating. This rating indicates an extremely strong
                  capacity to pay the preferred stock obligations.

         AA       High-quality, fixed-income security. The capacity to pay
                  preferred stock obligations is very strong, although not as
                  overwhelming as for issues rated "AAA."

         A        Backed by a sound capacity to pay the preferred stock
                  obligations, although it is somewhat more susceptible to the
                  adverse effects of changes in circumstances and economic
                  conditions.

         BBB      Backed by an adequate capacity to pay the preferred stock
                  obligations. Whereas the issuer normally exhibits adequate
                  protection parameters, adverse economic conditions or changing
                  circumstances are more likely to lead to a weakened capacity
                  to make payments for a preferred stock in this category than
                  for issues in the "A" category.


SHORT-TERM DEBT RATINGS

Thompson Bank Watch, Inc. ("TBW") assigns ratings to specific debt instruments
with original maturities of one year or less. The TBW Short-Term ratings
specifically assess the likelihood of an untimely payment of principal and
interest.

         TBW-1    Very high degree of likelihood that principal and interest
                  will be paid on a timely basis.

         TBW-2    While degree of safety regarding timely repayment of principal
                  and interest is strong, the relative degree is not as high as
                  for issues rated TBW-1.

         TBW-3    Lowest investment grade category. While more susceptible to
                  adverse developments than obligations with higher ratings,
                  capacity to service principal and interest in a timely fashion
                  is considered adequate.

         TBW-4    Non-investment grade and, therefore, speculative.

A BRIEF PREVIEW OF THE FUND

WHAT ARE THE GOALS OF ONE GROUP TECHNOLOGY FUND?

The Fund is designed to provide long-term capital growth.

WHAT IS THE FUND'S INVESTMENT STRATEGY?

The Fund normally will invest in equity securities of companies that have
developed, or are expected to develop, products, processes or services that will
provide significant technological advances and improvements, as well as
companies that will benefit significantly from such advances and improvements.
The Fund also may invest in debt securities and preferred stocks which are
convertible into common stock, and lend its portfolio securities.

WHAT ARE THE MAIN RISKS OF INVESTING IN THE FUND?

Equity securities such as those in which the Fund may invest are more volatile
and carry more risk than some other forms of investment. Accordingly, as with
all equity investments, you may lose money by investing in the Fund. The Fund
may invest in derivative securities. These securities may expose the Fund to
special risks. Additionally, because of the Fund's exposure to the technology
sector, economic developments affecting that sector will have a disproportionate
impact on the Fund. An investment in the Fund is not a deposit of Bank One
Corporation or its affiliates and is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency. For more
information about risks, please read "More About the Fund" and "Investment
Risks."

WHAT CLASSES OF SHARES ARE AVAILABLE?

The Fund currently offers four classes of Shares: Class A, Class B, Class C and
Class I. Class A, Class B and Class C shares are offered to the general public.
Class I shares are offered to institutional investors, including affiliates of
Bank One Corporation and any bank, depository institution, insurance company,
pension plan or other organization authorized to act in fiduciary, advisory,
agency, custodial or similar capacities. The section called "How To Do Business
With One Group Mutual Funds" will provide more information. Class I shares are
not available to Individual Retirement Accounts ("IRA").

HOW DO I PURCHASE AND REDEEM SHARES?

You may buy and redeem shares of the Fund on any day that the Fund is open for
business. Purchase and redemption procedures are explained in greater detail in
"How To Do Business With One Group Mutual Funds." For additional information,
call The One Group Services Company at 1-800-480-4111 or visit One Group Mutual
Fund's web site www.onegroup.com.

HOW ARE DIVIDENDS PAID?

Generally, dividends are declared on the last business day of each quarter and
are distributed periodically on the first business day of each quarter. Any
capital gains are distributed at least annually. Distributions are paid in
additional shares of the same class unless you elect to take the payment in
cash. For a more detailed discussion of dividends, see "Dividend Policies."

<PAGE>   74


WHO MANAGES THE FUND?

Banc One Investment Advisors Corporation ("Banc One Investment Advisors"), an
indirect subsidiary of Bank One Corporation, serves as the advisor of the Fund.
A more detailed discussion regarding Banc One Investment Advisors, its services
and compensation can be found in the Prospectus under the headings "The Advisor"
and "Shareholder Expenses."

ONE GROUP(R)

TECHNOLOGY FUND

INVESTMENT OBJECTIVE

The Fund seeks to provide long-term growth of capital.

PRINCIPAL INVESTMENT STRATEGY

   
The Fund invests primarily in equity securities of companies that Banc One
Investment Advisors believes have developed, or are expected to develop,
products, processes or services that will provide significant technological
advances and improvements, as well as companies whose processes or services will
benefit from such advances and improvements. These companies may include, for
example, companies that develop, produce or distribute products in the computer,
semi-conductor, electronics, communications, health care, and biotechnology
sectors. In selecting investments, Banc One Investment Advisors searches for
companies, regardless of size, whose stocks appear to be trading below their
true value. The Fund also will invest in companies that are positioned for
accelerated growth or higher earnings. Not all securities purchased by the Fund
will pay dividends.
    

PORTFOLIO SECURITIES

The Fund normally invests at least 65% of its total assets in common and
preferred stocks, rights, warrants, convertible securities, and other equity
securities of companies that develop or benefit from significant technological
advances or improvements. Up to 35% of the Fund's total assets may be invested
in U.S. government securities, other investment grade fixed income securities,
cash and cash equivalents. The Fund also may invest in the securities of foreign
issuers. The Fund also may engage in securities lending. For a list of all the
securities in which the Fund may invest, please read "Investment Practices."

RISK CONSIDERATIONS

The Fund invests in equity securities, which may increase or decrease in value.
As a result, the value of your investment in the Fund may increase or decrease
in value. The Fund also will invest in fixed income securities. The value of
these securities will change in response to interest rate changes and other
factors. This is especially true to the extent that the Fund invests in debt
securities in the lowest investment grade category. Such securities have
speculative characteristics. Because of its exposure to the technology industry,
economic developments affecting that industry will have a disproportionate
impact on the Fund. Before you invest, please read "More About the Fund" and
"Investment Practices."

FUND MANAGEMENT

The Fund is managed by a team of portfolio managers, research analysts, and
other investment management professionals. Each team member makes
recommendations about the securities in the Fund. The research analysts provide
in-depth industry analysis and recommendations, while the portfolio managers
determine strategy, industry weightings, Fund holdings, and cash positions.

(1)      If you buy or sell shares through a Shareholder Servicing Agent, you
         may be charged separate transaction fees by the Shareholder Servicing
         Agent. In addition, a $10.00 sub-minimum account fee may be applicable
         and a $7.00 charge will be deducted from the redemption amounts paid by
         wire.

(2)      Except for purchases of $1 million or more. Please see "Sales Charges."

(3)      Without the fee waiver, Investment Advisory Fees would be. 1.00% for
         all classes of shares.

(4)      Due to 12b-1 fees, long-term Class A, Class B and Class C shareholders
         may pay more than the equivalent of the maximum front-end sales charges
         permitted by the rules of the National Association of Securities
         Dealers. Without the voluntary waiver, 12b-1 fees would be .35% for
         Class A shares.

(5)      Total Operating Expenses have been revised to reflect fee waivers.
         Without the voluntary reduction of Investment Advisory and 12b-1 fees,
         Total Operating Expenses would be 1.85% for Class A shares, 2.50% for
         Class B shares, 2.50% for Class C shares, and 1.50% for Class I shares.

MORE ABOUT THE FUND

PORTFOLIO QUALITY

The Fund only purchases securities that meet certain rating criteria.

o        Corporate bonds generally will be rated in one of the three highest
         investment grade categories.

o        Banc One Investment Advisors reserves the right to invest in corporate
         bonds which present attractive opportunities and are rated in the
         lowest investment grade category. These corporate bonds may be riskier
         than higher rated bonds.

If the securities are unrated, Banc One Investment Advisors must determine that
they are of comparable quality to rated securities. Banc One Investment Advisors
will look at a security's rating at the time of investment. For more information
about ratings, please see "Description of Ratings" in the Appendix.

ILLIQUID INVESTMENTS

The Fund may invest up to 15% of its net assets in illiquid investments. A
security is illiquid if it cannot be sold at approximately the value assessed by
the Fund within seven (7) days. Banc One Investment Advisors will follow
guidelines adopted by the One Group Board of Trustees in determining whether an
investment is illiquid.

SPECIAL RISK CONSIDERATIONS

SECURITIES OF TECHNOLOGY COMPANIES: The Fund invests a significant portion of
its assets in the securities of companies in the technology sector. Because of
this focus, the Fund's performance is closely tied to and affected by this
sector. The stock price of technology companies tends to be more volatile than
the stock price of companies in other industries. Competitive pressures also may
have a significant effect on the financial condition of technology-sensitive
companies. For example, if technology continues to advance at an accelerated
rate, and the number of companies and product offerings continues to expand,
increasingly aggressive pricing may affect the profitability of companies in
which the Fund invests. In addition, because of the rapid pace of technological
development, products and services produced by companies in which the Fund
invests may become obsolete or have relatively short product cycles. As a result
the Fund's returns may be considerably more volatile than the returns of other
mutual funds that do not invest in similarly related companies.

DERIVATIVES: The Fund may invest in securities that are considered to be
"derivatives." Derivatives are securities or contracts that derive their value
from the performance of underlying assets or securities. These include:

o        options, futures contracts, and options on futures contracts

o        warrants

o        mortgage-backed securities, including collateralized mortgage
         obligations and Real Estate Mortgage Investment Conduits (CMOs and
         REMICs) and stripped mortgage-backed (Interest Only (IOs) and Principal
         Only (POs))

o        asset-backed securities

o        swap, cap and floor transactions

o        new financial products

These securities may be more volatile than other investments. Derivatives
present, to varying degrees, market, credit, leverage, liquidity, and management
risks. For a more detailed discussion of these risks, please read "Investment
Risks." A Fund's use of derivatives may cause the Fund to recognize higher
amounts of short-term capital gains (generally taxed at ordinary income tax
rates) than it would if the Fund did not use such instruments.

   
INTERNATIONAL INVESTMENTS: Investments in foreign securities involve risks
different from investments in U.S. securities. For more details, see "Investment
Practices" and "Investment Risks." Because of these risk factors, the share
price of a fund investing in foreign securities may be volatile, and you should 
    



                                       9
<PAGE>   80


be able to sustain sudden, and sometimes substantial, fluctuations in the value
of your investment. On January 1, 1999, the European Economic and Monetary Union
introduced the "Euro." The Euro will serve as a common currency for
participating European nations. All stocks issued by corporations located in
those nations will be denominated in Euros. In addition, outstanding shares have
been redenominated in Euros. All government bonds issued by participating
nations are in Euros, and outstanding government bonds have been redenominated
in Euros. The introduction of the Euro presents some uncertainties, such as the
adequacy of newly created accounting, clearing, settlement and payment systems
for the new currency. These uncertainties surrounding the introduction of the
Euro could adversely affect the value of the foreign securities held by the
Fund.

SMALL CAPITALIZATION COMPANIES: Investments in smaller, younger companies may be
riskier than investments in larger, more established companies. These companies
may be more vulnerable to changes in economic conditions, specific industry
conditions, market fluctuations, and other factors effecting the profitability
of other companies. Because economic events may have a greater impact on smaller
companies, there may be a greater and more frequent fluctuation in their stock
price. This may cause frequent and unexpected increases or decreases in the
value of your investment.

FIXED INCOME SECURITIES: Investments in fixed income securities (for example,
bonds) will increase or decrease in value based on changes in interest rates. If
rates increase, the value of a Fund's investments generally declines. On the
other hand, if rates fall, the value of the investments generally increases. The
value of your investment in a Fund will increase and decrease as the value of a
Fund's investments increase and decrease. While securities with longer duration
and maturities tend to produce higher yields, they also are subject to greater
fluctuations in value when interest rates change. Usually changes in the value
of fixed income securities will not affect cash income generated, but may affect
the value of your investment. Fixed income securities also are subject to the
risk that the issuer of the security will be unable to meet its repayment
obligation.

NON-DIVERSIFIED FUND: The Fund is "non-diversified." This means that the Fund
may invest a more significant portion of its assets in the securities of a
single issuer than can a "diversified" fund. In addition, the Fund's investments
are concentrated in the technology sector. This concentration increases the risk
of loss to the Fund by increasing its exposure to economic, business, political
or regulatory developments that may be adverse to the technology sector of the
economy.

HOW TO DO BUSINESS WITH ONE GROUP MUTUAL FUNDS

PURCHASING FUND SHARES

WHERE CAN I BUY SHARES?

You may purchase Fund shares from the following sources:

o        The One Group Services Company, and

o        Shareholder Servicing Agents. These include investment advisors,
         brokers, financial planners, banks, insurance companies, retirement or
         401(k) plan sponsors, or other intermediaries. Shares purchased this
         way will be held for you by the Shareholder Servicing Agent.

WHEN CAN I BUY SHARES?

o        Purchases may be made on any business day. This includes any day that
         the Fund is open for business, other than weekends, days on which the
         New York Stock Exchange ("NYSE") is closed, and the following holidays:
         New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
         Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving, and
         Christmas.

o        Purchase requests received by The One Group Services Company before 4
         p.m. Eastern Time ("ET") will be effective that day. On occasion, the
         NYSE will close before 4 p.m. ET. When that happens, purchase requests
         received after the NYSE closes will be effective the following business
         day.

o        Purchase orders may be cancelled by the Fund's Custodian, State Street
         Bank and Trust Company, if it does not receive "federal funds" by 4:00
         p.m. ET (i) on the business day after the order is placed if you are
         buying Class I shares, and (ii) on the third business day if you are
         purchasing Class A, Class B or Class C shares.

o        If your shares are held by a Shareholder Servicing Agent, it is the
         responsibility of the Shareholder Servicing Agent to send your purchase
         or redemption order to the Fund. Your Shareholder Servicing Agent may
         have an earlier cut-off time for purchase and redemption requests.

o        The One Group Services Company can reject a purchase order if it does
         not think that it is in the best interests of a Fund and/or its
         shareholders to accept the order.

o        Shares are electronically recorded. Therefore, certificates will not be
         issued.

WHAT KIND OF SHARES CAN I BUY?

One Group offers the following classes of shares:

o        Class A, Class B and Class C shares are available to the general
         public.

o        Class I shares are available to institutional investors and any
         organization authorized to act in a fiduciary, advisory, custodial or
         agency capacity. We will refer to these entities as "Intermediaries."

o        If you intend to hold your shares for six or more years, Class B shares
         may be more appropriate for you. If you intend to hold your shares for
         less than six years, you may want to consider Class A or Class C
         shares.

One Group Fund Direct IRA. One Group offers a retirement plan. This plan allows
participants to defer taxes while their retirement savings grow. Call The One
Group Services Company at 1-800-480-4111 for an Adoption Agreement.

HOW MUCH DO SHARES COST?

o        Shares are sold at net asset value ("NAV") plus a sales charge, if any.

o        Each class of shares in each Fund has a different NAV. This is
         primarily because each class has different distribution expenses.

o        NAV per share is calculated by dividing the total market value of a
         Fund's investments and other assets allocable to a class (minus class
         expenses) by the number of outstanding shares in that class.

o        A Fund's NAV changes every day. NAV is calculated each business day
         following the close of the NYSE at 4:00 p.m. ET. On occasion, the NYSE
         will close before 4 p.m. ET. When that happens, NAV will be calculated
         as of the time the NYSE closes.

HOW DO I OPEN AN ACCOUNT?

1.       Read the prospectus carefully.

2.       Decide how much you want to invest.

         o        The minimum initial investment is $1,000 ($100 for employees
                  of Bank One Corporation and its affiliates). The minimum
                  initial investment for an IRA is $250.

         o        Subsequent investments must be at least $100 ($25 for
                  employees of Bank One Corporation and its affiliates).

         o        You may purchase no more than $250,000 of Class B shares at
                  one time.

         o        The One Group Services Company may waive these minimums.

3.       Complete the Account Application Form. Be sure to sign up for all of

         to pay by wire or bank transfer) payable to "One Group" to:

         State Street Bank and Trust Company

         Investment Plan (see below).

6.       If you purchase shares through a Shareholder Servicing Agent, you may
         be required to complete additional forms or follow additional
         procedures. You should contact your Shareholder Servicing Agent
         regarding purchases, exchanges and redemptions.

CAN I PURCHASE SHARES OVER THE TELEPHONE?

Yes. Simply select this option on your Account Application Form and then:

o        Contact your Shareholder Servicing Agent or The One Group Services
         Company at 1-800-480-4111 to relay your purchase instructions.

o        Send a personal check made payable to "One Group" to State Street Bank
         and Trust Company (see address above), authorize a bank transfer, or
         initiate a wire transfer to the following wire address:

         State Street Bank and Trust Company
         Attn: Custody & Shareholder Services
         ABA 011 000 028

         FBO One Group Fund (ex: One Group Technology--A)
         Your Account Number (ex: 123456789)
         Your Account Registration (ex: John Smith & Mary Smith, JTWROS)

o        One Group uses reasonable procedures to confirm that instructions given
         by telephone are genuine. These procedures include recording telephone
         instructions and asking for personal identification. If these
         procedures are followed, One Group will not be responsible for any
         loss, liability, cost or expense of acting upon unauthorized or
         fraudulent instructions; you bear the risk of loss.

o        You may revoke your right to make purchases over the telephone by
         sending a letter to:

         State Street Bank and Trust Company
         c/o One Group
         P.O. Box 8528
         Boston, MA 02266-8528

CAN I AUTOMATICALLY INVEST ON A SYSTEMATIC BASIS?

Yes. After your Account is established, you may purchase additional Class A,
Class B and Class C shares by making automatic monthly investments from your
bank account. The minimum initial investment is still $1,000, but minimum
automatic additions are only $25. The One Group Services Company may waive these
minimums. To establish a Systematic Investment Plan:

o        Select the "Systematic Investment Plan" option on the Account
         Application Form.

o        Provide the necessary information about the bank account from which
         your investments will be made.

o        Shares purchased under a Systematic Investment Plan may not be redeemed
         for ten (10) calendar days.

o        One Group currently does not charge for this service, but may impose a
         charge in the future. However, your bank may impose a charge for
         debiting your bank account.

o        You may revoke your right to make systematic investments by calling The
         One Group Services Company at 1-800-480-4111 or by sending a letter to:

         State Street Bank and Trust Company
         c/o One Group
         P.O. Box 8528
         Boston, MA 02266-8528


CONVERSION FEATURE

Your Class B shares automatically convert to Class A shares after eight years
(measured from the end of the month in which they were purchased).




                                       13
<PAGE>   84


o        After conversion, your shares will be subject to the lower distribution
         and shareholder servicing fees charged on Class A shares.

o        You will not be assessed any sales charges or fees for conversion of
         shares, nor will you be subject to any Federal income tax.

o        Because the share price of the Class A shares may be higher than that
         of the Class B shares at the time of conversion, you may receive fewer
         Class A shares; however, the dollar value will be the same.

o        If you have exchanged Class B shares of one Fund for Class B shares of
         another, the time you held the shares in each Fund will be added
         together.

SALES CHARGES

The One Group Services Company compensates Shareholder Servicing Agents who sell
shares of One Group. Compensation comes from sales charges, 12b-1 fees and
payments by The One Group Services Company from its own resources. Occasionally,
The One Group Services Company, at its own expense, also will provide cash
incentives which will be paid to select Shareholder Servicing Agents. Those
Shareholder Servicing Agents who may receive special incentives include Banc One
Securities Corporation, The Advisors Group, United Planners Financial Services
of America, Inc., The Legend Group, and Rosewood Retirement Advisory Services,
LLC. The One Group Services Company pays additional compensation to Shareholder
Servicing Agents for sales of over $1 million dollars of Class A shares.
Shareholder Servicing Agents receive 1.00% of the purchase price of Class A
shares for sales of $1 million to $5 million, and 0.50% on amounts over $5
million.

         the equivalent of 1% of the purchase price if you redeem any or all of
         the Class A shares within one year of purchase and 0.50% of the
         purchase price if you redeem within two years of purchase, unless The
         One Group Services Company receives notice before you invest indicating
         that your Shareholder Servicing Agent is waiving its commission.

</TABLE>

Shareholder Servicing Agents selling Class C shares receive a commission of
1.00% of the original purchase price from The One Group Services Company.

How the CDSC is Calculated

o        The Fund assumes that all purchases made in a given month were made on
         the first day of the month.

o        The CDSC is based on the current market value or the original cost of
         the shares, whichever is less.

o        A sales charge is not imposed on increases in NAV above the initial
         purchase price, nor is a sales charge assessed on shares acquired
         through reinvestment of dividends or capital gains distributions.

o        To keep your CDSC as low as possible, the Fund first will redeem any
         shares in your account that carry no CDSC, starting with Class A
         Shares. After that, the Fund will redeem the shares you have held for
         the longest time and thus have the lowest CDSC.

o        If you exchange Class B or Class C shares of an unrelated mutual fund
         for Class B or Class C shares of One Group in connection with a fund
         reorganization, the CDSC applicable to your original shares (including
         the period of time you have held those shares) will be applied to One
         Group shares you receive in the reorganization.

12b-1 FEES

12b-1 fees are paid by One Group to The One Group Services Company as
compensation for its services and expenses. The One Group Services Company in
turn pays all or part of the 12b-1 fee to Shareholder Servicing Agents that sell
shares of One Group.

o        The 12b-1 fees vary by share class as follows:

         1.       Class A shares pay a 12b-1 fee of .35% of the average daily
                  net assets of the Fund, which is currently being waived to
                  .25%.

         2.       Class B and Class C shares pay a 12b-1 fee of 1.00% of the
                  average daily net assets of the Fund. This will cause expenses
                  for Class B and Class C shares to be higher and dividends to
                  be lower than for Class A shares.

         3.       There are no 12b-1 fees for Class I shares.

o        12b-1 fees, together with the CDSC, help The One Group Services Company
         sell Class B and Class C shares without an "up-front" sales charge by
         defraying the costs of advancing brokerage commissions and other
         expenses paid to Shareholder Servicing Agents.

         o        The One Group Services Company may use up to .25% of the fees
                  for shareholder servicing and up to .75% for distribution.
                  During the last fiscal year, The One Group Services Company
                  received 12b-1 fees totaling .25% and 1.00% of the average
                  daily net assets of Class A and Class B shares, respectively.

         o        The One Group Services Company may pay 12b-1 fees to its
                  affiliates and to Banc One Investment Advisors and its
                  affiliates (or any sub-advisor) for brokerage and other agency
                  transactions.

SALES CHARGE REDUCTIONS AND WAIVERS

REDUCING YOUR CLASS A SALES CHARGES

There are several ways you can reduce the sales charges you pay on Class A
shares:

1.       Right of Accumulation: You may add the market value of any Class A,
         Class B or Class C shares of a Fund (except a money market fund) that
         you (and your spouse and minor children) already own to the amount of
         your next Class A purchase for purposes of calculating the sales
         charge. An Intermediary also may take advantage of this option.

2.       Letter of Intent: With an initial investment of $2,000, you may
         purchase Class A shares of one or more funds over the next 13 months
         and pay the same sales charge that you would have paid if all shares
         were purchased at once. A percentage of your investment will be held in
         escrow until the full amount covered by the Letter of Intent has been
         invested.

To take advantage of the accumulation privilege or letter of intent, complete
the appropriate section of your fund application, or contact your investment
representative. To determine if you are eligible for the accumulation privilege,
contact The One Group Services Company at 1-800-480-4111. These programs may be
terminated or amended at any time.

EXCHANGING FUND SHARES

WHAT ARE MY EXCHANGE PRIVILEGES?

You may make the following exchanges:

o        Class I shares of a Fund may be exchanged for Class A shares of that
         Fund or for Class A or Class I shares of another One Group Fund.

o        Class A shares of a Fund may be exchanged for Class I shares of that
         Fund or for Class A or Class I shares of another One Group Fund, but
         only if you are eligible to purchase those shares.

o        Class B shares of a Fund may be exchanged for Class B shares of another
         One Group Fund.

o        Class C shares of a Fund may be exchanged for Class C shares of another
         One Group Fund.

One Group Funds offer a Systematic Exchange Privilege which allows you to
automatically exchange shares of one fund to another on a monthly or quarterly
basis. This privilege is useful in Dollar Cost Averaging. To participate in this
privilege, please select it on your account application. To learn more about it,
please call The One Group Services Company at 1-800-480-4111.

One Group does not charge a fee for this privilege. In addition, One Group may
change the terms and conditions of your exchange privileges upon 60 days written
notice.

WHEN ARE EXCHANGES PROCESSED?

Exchanges are processed the same business day they are received, provided:

o        State Street Bank and Trust Company receives the request by 4:00 p.m.,
         ET.

o        You have provided One Group with all of the information necessary to
         process the exchange.

o        You have received a current prospectus of the Fund or Funds in which
         you wish to invest.

o        You have contacted your Shareholder Servicing Agent, if necessary.

DO I PAY A SALES CHARGE ON AN EXCHANGE?

Generally, you will not pay a sales charge on an exchange. However:

o        You will pay a sales charge if you own Class I shares of a Fund and you
         want to exchange those shares for Class A shares, unless you qualify
         for a sales charge waiver (see above).

o        You will pay a sales charge if you bought Class A shares of a Fund:

1.       That does not charge a sales charge and you want to exchange them for
         shares of a Fund that does, in which case you would pay the sales
         charge applicable to the Fund into which you are exchanging.

2.       That charged a lower sales charge than the Fund into which you are
         exchanging, in which case you would pay the difference between that
         Fund's sales charge and all other sales charges you have already paid.

o        If you exchange Class B or Class C shares of a Fund, you will not pay a
         sales charge at the time of the exchange, however:

1.       Your new Class B or Class C shares will be subject to the higher CDSC
         of either the Fund from which you exchanged, the Fund into which you
         exchanged, or any Fund from which you previously exchanged.

2.       The current holding period for your exchanged Class B or Class C shares
         is carried over to your new shares.


                                       19
<PAGE>   90


ARE EXCHANGES TAXABLE?

Generally:

o        An exchange between classes of shares of the same Fund is not taxable
         for Federal income tax purposes.

o        An exchange between Funds is considered a sale and generally results in
         a capital gain or loss for Federal income tax purposes.

o        You should talk to your tax advisor before making an exchange.

ARE THERE LIMITS ON EXCHANGES?

Yes. The exchange privilege is not intended as a way for you to speculate on
short term movements in the market. Therefore:

o        To prevent disruptions in the management of the Funds, One Group limits
         excessive exchange activity.

o        Exchange activity is excessive if it EXCEEDS TWO SUBSTANTIVE EXCHANGE
         REDEMPTIONS (WITHIN 30 DAYS OF EACH OTHER) WITHIN A TWELVE MONTH
         PERIOD.

o        In addition, One Group reserves the right to reject any exchange
         request (even those that are not excessive) if the Fund reasonably
         believes that the exchange will result in excessive transaction costs
         or otherwise adversely affect other shareholders.

You may redeem all or some of your shares on any day that the Fund is open for

<PAGE>   91


o        On the Account Application Form you may elect to have the redemption
         proceeds mailed or wired to:

         2.       State Street Bank and Trust Company or your Shareholder
                  Servicing Agent.

o        State Street Bank and Trust Company may charge you a wire redemption
         fee. The current charge is $7.00.

         of the redemption request.

WHAT WILL MY SHARES BE WORTH?

         receive that day's NAV.

o        If you own Class B or Class C shares and the Fund receives your
         redemption request by 4:00 p.m. ET (or when the NYSE closes), you will
         receive that day's NAV, minus the amount of any applicable CDSC.

CAN I REDEEM BY TELEPHONE?

         fee. The current charge is $7.00.

o        One Group uses reasonable procedures to confirm that instructions given
         by telephone are genuine. These procedures include recording telephone
         instructions and asking for personal identification. If these
         procedures are followed, One Group will not be responsible for any
         loss, liability, cost or expense of acting upon unauthorized or
         fraudulent instructions; you bear the risk of loss.

o        REDEMPTIONS FROM YOUR IRA ACCOUNT MAY NOT BE MADE BY TELEPHONE.

CAN I REDEEM ON A SYSTEMATIC BASIS?

If you have an account value of at least $10,000, you may elect to receive

o        Select the "Systematic Withdrawal Plan" option on the Account
         Application Form.

o        Specify the amount you wish to receive and the frequency of the
         payments.

o        You may designate a person other than yourself as the payee.

o        There is no charge for this service.

o        If you select this option, please keep in mind that:

         1.       It may not be in your best interest to buy additional Class A
                  shares while participating in a Systematic Withdrawal Plan.
                  This is because Class A shares have an up-front sales charge.

         2.       If you own Class B or Class C shares, you or your designated
                  payee may receive systematic payments provided the payments
                  are limited to no more than 10% of your account value
                  annually, measured from the date the redemption request is
                  received.


                                       21
<PAGE>   92


         3.       If you are age 70-1/2, you may elect to receive payments to
                  the extent that the payment represents a minimum required
                  distribution from an IRA or other qualifying retirement plan.

         4.       If the amount of the systematic payment exceeds the income
                  earned by your account since the previous payment under the
                  Systematic Withdrawal Plan, payments will be made by redeeming
                  some of your shares. This will reduce the amount of your
                  investment.

ADDITIONAL INFORMATION REGARDING REDEMPTIONS

o        All redemptions will be for cash.

o        If you redeem shares for which you paid by check, and One Group has not
         yet received payment on the check, One Group will delay forwarding your
         redemption proceeds for 10 or more days until payment has been
         collected from your bank.

o        Because of the high cost of handling small investments, One Group
         charges a sub-minimum account fee. Accounts under $1,000 that are not
         participating in a Systematic Investment Plan will be assessed an
         annual fee of $10.00. The sub-minimum account fee will not apply to IRA
         accounts and the accounts of employees of BANK ONE CORPORATION and its
         affiliates.

o        One Group may suspend your ability to redeem when:

         1.       Trading on the New York Stock Exchange ("NYSE") is restricted.

         2.       The NYSE is closed (other than weekend and holiday closings).

         3.       The SEC has permitted a suspension.

         4.       An emergency exists.

         The Statement of Additional Information offers more details about this
         process.

o        You generally will recognize a gain or loss on a redemption for Federal
         income tax purposes. You should talk to your tax advisor before making
         a redemption.

SHAREHOLDER INFORMATION

VOTING RIGHTS

The Fund does not hold annual shareholder meetings, but may hold special
meetings. The special meetings are held, for example, to elect or remove
Trustees, change the Fund's fundamental investment objective, or approve an
investment advisory contract.

As a Fund shareholder, you have one vote for each share that you own. Each Fund,
and each class of shares within each Fund, vote separately on matters relating
solely to that Fund or class, or which affect that Fund or class differently.
However, all shareholders will have equal voting rights on matters that affect
all shareholders equally.

DIVIDEND POLICIES

DIVIDENDS

The Fund generally declares dividends on the last business day of each quarter.
Dividends are distributed on the first business day of the next quarter. Capital
gains, if any, for the Fund is distributed at least annually.

The Fund pays dividends and distributions on a per-share basis. This means that
the value of your shares will be reduced by the amount of the payment. If you
purchase shares shortly before the record date for a dividend or the
distribution of capital gains, you will pay the full price for the shares and
receive some portion of the price back as a taxable dividend or distribution.

Dividends payable on Class I shares will be more than those payable on other
classes of shares. This is because Class A, Class B and Class C shares have
higher distribution expenses.

DIVIDEND REINVESTMENT

You automatically will receive all income dividends and capital gain
distributions in additional shares of the same Fund and class, unless you have
elected to take such payment in cash. The price of the shares is the NAV
determined immediately following the dividend record date. Reinvested dividends
and distributions receive the same tax treatment as dividends and distributions
paid in cash.

If you want to change the way in which you receive dividends and distributions,
you must write to State Street Bank & Trust Company at P.O. Box 8528, Boston, MA

SPECIAL DIVIDEND RULES FOR CLASS B SHARES

Class B shares received as dividends and capital gains distributions will be
accounted for separately. Each time any Class B shares (other than those in the
sub-account) convert to Class A shares, a percentage of the Class B shares in
the sub-account will also convert to Class A shares. (See "Conversion Feature.")

TAX TREATMENT OF THE FUND

TAX STATUS OF THE FUND

The Fund intends to qualify as a "regulated investment company" for Federal
income tax purposes. If the Fund qualifies, as it has in the past, it will pay
no federal income tax on the earnings it distributes to shareholders.

TAX TREATMENT OF SHAREHOLDERS

TAXATION OF SHAREHOLDER TRANSACTIONS

A sale, exchange, or redemption of Fund shares generally will produce either a
taxable gain or a loss. You are responsible for any tax liabilities generated by
your transactions.

TAXATION OF DISTRIBUTIONS

The Fund will distribute substantially all of its net investment income
(including, for this purpose, the excess of net short-term capital gains over
net long-term capital losses and net capital gains (i.e., the excess of net
long-term capital gains over net short-term capital losses) on at least an
annual basis. Dividends you receive from the Fund, whether reinvested or
received in cash, will be taxable to you. Dividends from a Fund's net investment
income will be taxable as ordinary income and distributions from the Fund's
long-term capital gains will be taxable to you as such, regardless of how long
you have held the shares. Distributions are taxable to you even if they are paid
from income or gains earned by the Fund prior to your investment (and thus were
included in the price you paid).

Dividends paid in January, but declared in October, November or December of the
previous year, will be considered to have been paid in the previous year.

TAXATION OF RETIREMENT PLANS

Distributions by the Fund to qualified retirement plans generally will not be
taxable. However, if shares are held by a plan that ceases to qualify for
tax-exempt treatment or by an individual who has received shares as a
distribution from a retirement plan, the distributions will be taxable to the
plan or individual as described in "Taxation of Distributions." If you are
considering purchasing shares with qualified retirement plan assets, you should
consult your tax advisor for a more complete explanation of the Federal, state,
local and (if applicable) foreign tax consequences of making such an investment.

TAX INFORMATION

The Form 1099 that is mailed to you every January details your dividends and
their federal tax category. Even though the Fund provides you with this
information, you are responsible for verifying your tax liability with your tax
professional. For additional tax information see the Statement of Additional
Information. Please note that this tax discussion is general in nature; no
attempt has been made to present a complete explanation of the Federal, state,
local or foreign tax treatment of the Fund or their shareholders.

Group Services Company at 3435 Stelzer Road, Columbus, OH 43219 or call

ORGANIZATION AND MANAGEMENT OF THE FUND

THE FUND

The Fund is a series of One Group Mutual Funds, an open-end management
investment company. One Group currently offers of 53 separate Funds. The other
Funds are described in separate prospectuses. The Fund described in this
prospectus is non-diversified. Each Fund of One Group Mutual Funds is supervised
by the Board of Trustees.

THE BOARD OF TRUSTEES

The Trustees oversee the management and administration of the Fund. The Trustees
are responsible for making major decisions about the Fund's investment
objectives and policies, but delegate the day-to-day administration of the Fund
to the officers of One Group.

THE ADVISOR

Banc One Investment Advisors makes the day-to-day investment decisions for the
Fund and continuously reviews, supervises and administers the Fund's investment
programs. Banc One Investment Advisors has served as investment advisor to One
Group since 1993. Prior to that time, One Group was advised by affiliates of
Banc One Investment Advisors. In addition to One Group, Banc One Investment
Advisors serves as investment advisor to other mutual funds and individual,
corporate, charitable and retirement accounts. As of March 29, 1999, Banc One
Investment Advisors, an indirect, wholly-owned subsidiary of Bank One
Corporation, managed over $120 billion in assets.


THE DISTRIBUTOR

The One Group Services Company, 3435 Stelzer Road, Columbus, Ohio 43219, a
wholly-owned subsidiary of The BISYS Group, Inc., markets the Fund and
distributes shares through selling brokers, financial institutions, investment
advisors, and other financial representatives.

THE ADMINISTRATOR AND SUB-ADMINISTRATOR

The One Group Services Company also serves as the Fund's administrator. The One
Group Services Company is responsible for responding to shareholder inquiries
and requests for information, as well as providing regulatory compliance and
reporting. For these services, The One Group Services Company receives a fee
based on the total assets of One Group. For the first $1.5 billion in One Group
assets, The One Group Services Company receives an annual fee of .20% of each
Fund's average daily net assets. The annual rate declines to .18% on assets up
to $2 billion, and to .16% when assets exceed $2 billion. The fee is calculated
daily and paid monthly. Some One Group funds are not included in the
calculations. Banc One Investment Advisors, the Sub-Administrator, provides
office space, equipment, and facilities, as well as legal and regulatory
support.

THE TRANSFER AGENT, CUSTODIAN AND SUB-CUSTODIAN

State Street Bank and Trust Company, P.O. Box 8528, Boston, MA 02266-8528, or
your Shareholder Servicing Agent, if appropriate, handles shareholder
recordkeeping and statementing, distributes dividends, and processes buy and
sell requests. As the Fund's custodian, State Street holds the Fund's assets,
settles all portfolio trades and assists in calculating the Fund's net asset
values. Bank One Trust Company, N.A. serves as sub-custodian in connection with
the Funds' securities lending activities under an agreement with State Street
Bank and Trust Company. Bank One Trust Company, N.A. is paid a fee by the Fund
for this service.

YEAR 2000

Preparing for the Year 2000 is a high priority for One Group. Both The One Group
Services Company and Banc One Investment Advisors have formed dedicated teams to
help them successfully achieve Year 2000 compliance. In addition, these teams
are responsible for assessing the readiness of all other service providers to
One Group. Year 2000 remediation efforts are directed toward both information
technology and non-information technology systems. Non-information technology
systems include elevators, photocopy machines, and facsimile machines, and
should have no significant impact on the delivery of services to One Group.


                                       25
<PAGE>   96


Banc One Investment Advisors has identified 49 information technology systems
and interfaces that provide service and support to One Group. Each system is
assigned a priority rating: high, medium or low. Systems rated "high" are those
which are essential to the operation of One Group. Each system rated "high" was
scheduled to be Year 2000 compliant by December 31, 1998. All systems will be
tested for compliance throughout 1999.

Many, if not all, of the systems are owned or operated by third party servicers
(for example, One Group's Custodian). Consequently, remediation efforts must be
made by those servicers. Banc One Investment Advisors and The One Group Services
Company have, and will continue to, monitor the remediation progress of the
service providers. This process involves documentation, on-site visits, and
review of remediation plans and test results. Both Banc One Investment Advisors
and The One Group Services Company have budgeted in excess of $700,000 in fiscal
year 1998 and over $1 million in fiscal year 1999 toward the remediation effort
for all systems and interfaces. Neither One Group nor its shareholders will bear
any of the direct remediation expenses.

Neither The One Group Services Company nor Banc One Investment Advisors
currently anticipates that the move to Year 2000 will have a material impact on
their ability to continue to provide the Fund with service at current levels.
Likewise, One Group currently anticipates that the move to Year 2000 will not
have a material impact on its operations.

INVESTMENT RISKS

Below is a more complete discussion of the types of risks inherent in the
securities and investment techniques listed above. Because of these risks, the
value of the securities held by the Fund may fluctuate, as will the value of
your investment in the Fund. Certain investments are more susceptible to these
risk than others.

o        CREDIT RISK. The risk that the issuer of a security, or the
         counterparty to a contract, will default or otherwise become unable to
         honor a financial obligation. Credit risk is generally higher for
         non-investment grade securities. The price and liquidity of a security
         can be adversely affected prior to actual default as its credit status
         deteriorates and the probability of default rises.

   
o        LEVERAGE RISK. The risk associated with securities or 
         practices that multiply small index or market movements into large
         changes in value. Leverage is often associated with investments in
         derivatives, but also may be embedded directly.

         o        HEDGED. When a derivative (a security whose value is based on
                  another security or index) is used as a hedge against an
                  opposite position that the fund also holds, any loss generated
                  by the derivative should be substantially offset by gains on
                  the hedged investment, and vice versa. While hedging can
                  reduce or eliminate losses, it can also reduce or eliminate
                  gains. Hedges are sometimes subject to imperfect matching
                  between the derivative and underlying security, and there can
                  be no assurance that a Fund's hedging transactions will be
                  effective.

         o        SPECULATIVE. To the extent that a derivative is not used as a
                  hedge, the fund is directly exposed to the risks of that
                  derivative. Gains or losses from speculative positions in a
                  derivative may be substantially greater than the derivative's
                  original cost.
    

o        LIQUIDITY RISK. The risk that certain securities may be difficult or
         impossible to sell at the time and the price that would normally
         prevail in the market. The seller may have to lower the price, sell
         other securities instead or forego an investment opportunity, any of
         which could have a negative effect on fund management or performance.
         This includes the risk of missing out on an investment opportunity
         because the assets necessary to take advantage of it are tied up in
         less advantageous investments.


                                       29
<PAGE>   100


o        MANAGEMENT RISK. The risk that a strategy used by a fund's management
         may fail to produce the intended result. This includes the risk that
         changes in the value of a hedging instrument will not match those of
         the asset being hedged. Incomplete matching can result in unanticipated
         risks.

o        MARKET RISK. The risk that the market value of a security may move up
         and down, sometimes rapidly and unpredictably. These fluctuations may
         cause a security to be worth less than the price originally paid for
         it, or less than it was worth at an earlier time. Market risk may
         affect a single issuer, industry, sector of the economy or the market
         as a whole. There is also the risk that the current interest rate may
         not accurately reflect existing market rates. For fixed income
         securities, market risk is largely, but not exclusively, influenced by
         changes in interest rates. A rise in interest rates typically causes a
         fall in values, while a fall in rates typically causes a rise in
         values. Finally, key information about a security or market may be
         inaccurate or unavailable. This is particularly relevant to investments
         in foreign securities.

o        POLITICAL RISK. The risk of losses attributable to unfavorable
         governmental or political actions, seizure of foreign deposits, changes
         in tax or trade statutes, and governmental collapse and war.

o        FOREIGN INVESTMENT RISK. The risk associated with higher transaction
         costs, delayed settlements, currency controls and adverse economic
         developments. This also includes the risk that fluctuations in the
         exchange rates between the U.S. dollar and foreign currencies may
         negatively affect an investment. Adverse changes in exchange rates may
         erode or reverse any gains produced by foreign currency denominated
         investments and may widen any losses. Exchange rate volatility also my
         affect the ability of an issuer to repay U.S. dollar denominated debt,
         thereby increasing credit risk.

o        PRE-PAYMENT RISK. The risk that the principal repayment of a security
         will occur at an unexpected time, especially that the repayment of a
         mortgage or asset-backed security occurs either significantly sooner or
         later than expected. Changes in pre-payment rates can result in greater
         price and yield volatility. Pre-payments generally accelerate when
         interest rates decline. When mortgage and other obligations are
         pre-paid, a Fund may have to reinvest in securities with a lower yield.
         Further, with early prepayment, a Fund may fail to recover any premium
         paid, resulting in an unexpected capital loss.

o        TAX RISK. The risk that the issuer of the securities will fail to
         comply with certain requirements of the Internal Revenue Code, which
         would cause adverse tax consequences.

o        REGULATORY RISK. The risk associated with Federal and state laws which
         may restrict the remedies that a lender has when a borrower defaults on
         loans. These laws include restrictions on foreclosures, redemption
         rights after foreclosure, Federal and state bankruptcy and debtor
         relief laws, restrictions on "due on sale" clauses, and state usury
         laws.

INVESTMENT POLICIES

The Fund's investment objective and the investment policies summarized below are
fundamental. This means that they cannot be changed without the consent of a
majority of the outstanding shares of the Fund. The full text of the fundamental
policies can be found in the Statement of Additional Information.

The Fund may not:

1.       Purchase an issuer's securities if as a result more than 25% of its
         total assets would be invested in the securities of that issuer. This
         restriction applies with respect to 50% of a Fund's total assets. With
         respect to the remaining 50% of the Fund's total assets, it may not
         purchase an issuer's securities if as a result more than 5% of its
         total assets would be invested in the securities of that issuer. This
         does not include securities issued or guaranteed by the United States,
         its agencies or instrumentalities, and repurchase agreements involving
         these securities.

2.       Concentrate its investments in the securities of one or more issuers
         conducting their principal business in a particular industry or group
         of industries (except the technology sector). This does not include
         obligations issued or guaranteed by the U.S. government or its agencies
         and instrumentalities and repurchase agreements involving such
         securities.

3.       Make loans, except that a Fund may (i) purchase or hold debt
         instruments in accordance with its investment objective and policies;
         (ii) enter into repurchase agreements; and (iii) engage in securities
         lending.

Additional investment policies can be found in the Statement of Additional
Information.



TEMPORARY DEFENSIVE POSITION

Sometimes Banc One Investment Advisors decides that the Fund should temporarily
be invested up to 100% in cash and cash equivalents. Cash equivalents include:

o        Securities issued by the U.S. Government, its agencies and
         instrumentalities

o        Repurchase Agreements

o        Certificates of Deposit

o        Bankers' Acceptances

o        Commercial Paper (rated in one of the two highest rating categories)

o        Variable Rate Master Demand Notes

o        Bank Money Market Deposit Accounts

While the Fund is engaged in a temporary defensive position, it will not be
pursuing its investment objectives. Therefore, the Fund will pursue a temporary
defensive position only when market conditions warrant.

PORTFOLIO TURNOVER

Portfolio turnover may vary greatly from year to year, as well as within a
particular year.

Higher portfolio turnover rates will likely result in higher transaction costs
to the Fund and may result in additional tax consequences to you. The portfolio
turnover rate for the Fund is not estimated to exceed 100%. To the extent
portfolio turn over results in short-term capital gains, such gains will
generally be taxed at ordinary income tax rates.

APPENDIX

DESCRIPTION OF RATINGS

The following is a summary of published ratings by major credit rating agencies.
Credit ratings evaluate only the safety of principal and interest payments, not
the market value risk of lower quality securities. Credit rating agencies may
fail to change credit ratings to reflect subsequent events on a timely basis.
Although Banc One Investment Advisors considers security ratings when making
investment decisions, it also performs its own investment analysis and does not
rely solely on the ratings assigned by credit agencies.

         Unrated securities will be treated as non-investment grade securities
unless Banc One Investment Advisors determines that such securities are the
equivalent of investment grade securities. Securities that have received
different ratings from more than one agency are considered investment grade if
at least one agency has rated the security investment grade.

DESCRIPTION OF COMMERCIAL PAPER RATINGS

DUFF & PHELPS CREDIT RATING CO. ("DUFF")

         D-1+     Highest certainty of timely payment. Short-term liquidity,
                  including internal operating factors and/or access to
                  alternative sources of funds, is outstanding and safety is
                  just below risk-free U.S. Treasury obligations.

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

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

STANDARD & POOR'S CORPORATION ("S&P")

         A-1      Highest category of commercial paper. Capacity to meet
                  financial commitment is strong. Obligations designated with a
                  plus sign (+) indicate that capacity to meet financial
                  commitment is extremely strong.

         A-2      Issues somewhat more susceptible to adverse effects of changes
                  in circumstances and economic conditions than obligations in
                  higher rating categories. However, the capacity to meet
                  financial commitments is satisfactory.

FITCH'S IBCA INC. ("FITCH")

         F1       Highest capacity for timely repayment. Those issues rated F1+
                  possess a particularly strong credit feature.

         F2       Satisfactory capacity for timely repayment although such
                  capacity may be susceptible to adverse changes in business,
                  economic or financial conditions.

MOODY'S INVESTORS SERVICE ("MOODY'S")

PRIME-1  Superior ability for repayment.

PRIME-2  Strong ability for repayment.

DESCRIPTION OF BANK RATINGS

MOODY'S

These ratings represent Moody's opinion of a bank's intrinsic safety and
soundness.

         A        These banks possess exceptional intrinsic financial strength.
                  Typically they will be major financial institutions with
                  highly valuable and defensible business franchises, strong
                  financial fundamentals, and a very attractive and stable
                  operating environment.


                                       32
<PAGE>   103


         B        These banks possess strong intrinsic financial strength.
                  Typically, they will be important institutions with valuable
                  and defensible business franchises, good financial
                  fundamentals, and an attractive and stable operating
                  environment.

         C        These banks possess good intrinsic financial strength.
                  Typically, they will be institutions with valuable and
                  defensible business franchises. These banks will demonstrate
                  either acceptable financial fundamentals within a stable
                  operating environment, or better than average financial
                  fundamentals within an unstable operating environment.

S&P

S&P's credit rating is a current opinion of an obligor's overall financial
capacity (its creditworthiness) to pay its financial obligation.

         Aaa      The highest rating assigned by S&P. The obligor's capacity to
                  meet its financial commitment on the obligation is extremely
                  strong.

         Aa       The obligor's capacity to meet its financial commitments on
                  the obligation is very strong.

         A        The obligation is somewhat more susceptible to the adverse
                  effects of changes in circumstances and economic conditions
                  than obligations in higher rated categories. However, the
                  obligor's capacity to meet its financial commitment on the
                  obligation is still strong.

DESCRIPTION OF INSURANCE RATINGS

MOODY'S

These ratings represent Moody's opinions of the ability of insurance companies
to pay punctually senior policyholder claims and obligations.

         Aaa      Insurance companies rated in this category offer exceptional
                  financial security. While the financial strength of these
                  companies is likely to change, such changes as can be
                  visualized are most unlikely to impair their fundamentally
                  strong position.

         Aa       These insurance companies offer excellent financial security.
                  Together with the Aaa group, they constitute what are
                  generally known as high grade companies. They are rated lower
                  than Aaa companies because long-term risks appear somewhat
                  larger.

         A        Insurance companies rated in this category offer good
                  financial security. However, elements may be present which
                  suggest a susceptibility to impairment sometime in the future.

S&P

S&P's credit rating is a current opinion of the creditworthiness of an obligor
with respect to a specific financial obligation, a specific class of financial
obligations, or a specific financial program.

         AAA      This is the highest rating assigned by S&P. The obligor's
                  capacity to meet its financial commitment on the obligation is
                  extremely strong.

         AA       The obligor's capacity to meet its financial commitments on
                  the obligation is very strong.

         A        An obligation rated A is somewhat more susceptible to the
                  adverse effects of changes in circumstances and economic
                  conditions than obligations in higher rated categories.
                  However, the obligor's capacity to meet its financial
                  commitment on the obligation is still strong.

DESCRIPTION OF CORPORATE BOND RATINGS

S&P

Investment Grade

         AAA      The highest rating. The rating indicates an extremely strong
                  capacity to meet its financial commitment.

         AA       Differs from AAA issues only in a small degree. The obligor's
                  capacity to meet its financial commitment is very strong.

         A        These bonds are somewhat more susceptible to the adverse
                  effects of changes in circumstances and economic conditions
                  than debt in higher rated categories. However, capacity to
                  meet its financial commitment on the obligation is still
                  strong.

         BBB      Exhibits adequate protection parameters. However, adverse
                  economic conditions or changing circumstances are more likely
                  to lead to a weakened capacity to meet its financial
                  commitment on the obligation.

Non-Investment Grade

         BB       Less vulnerable to non-payment than other speculative issues.
                  However, these bonds face major ongoing uncertainties or
                  exposure to adverse business, financial or economic conditions
                  which could lead to inadequate capacity to meet financial
                  commitment on the obligation.

         B        More vulnerable to non-payment than obligations rated BB, but
                  currently has the capacity to meet its financial commitment on
                  the obligation. Adverse business, financial or economic
                  conditions will likely impair capacity or willingness to meet
                  its financial commitment on the obligation.

         CCC      Currently vulnerable to non-payment, and is dependent upon
                  favorable business, financial, and economic conditions to meet
                  its financial commitment on the obligation. In the event of
                  adverse business, financial, or economic conditions, they are
                  not likely to have the capacity to meet its financial
                  commitment on the obligation.

         CC       Currently highly vulnerable to non-payment.

         C        This rating may be used to cover a situation where a
                  bankruptcy petition has been filed, or similar action has been
                  taken, but payments on this obligation are being continued.

         D        Bonds in payment default.

Ratings from AA to CCC may be modified by a plus (+) or minus (-) to show
relative standing within the major rating categories.

MOODY'S

Investment Grade

         Aaa      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 an exceptionally stable,
                  margin and principal is secure.

         Aa       High quality by all standards. Margins of protection may not
                  be as large as in Aaa securities, fluctuation of protective
                  elements may be greater, or there may be other elements
                  present that make the long-term risks appear somewhat larger
                  than in Aaa securities.

         A        These bonds possess many favorable investment attributes and
                  are to be considered as upper-medium grade obligations.
                  Factors giving security to principal and interest are
                  considered adequate, but elements may be present which suggest
                  a susceptibility to impairment sometime in the future.

         Baa      These bonds are considered 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.

Non-Investment Grade

         Ba       These bonds have speculative elements; their future cannot be
                  considered as well assured. The protection of interest and
                  principal payments may be very moderate and thereby not well
                  safeguarded during good and bad times over the future.

         B        These bonds lack the characteristics of a desirable investment
                  (i.e., potentially low assurance of timely interest and
                  principal payments or maintenance of other contract terms over
                  any long period of time may be small).

         Caa      Bonds in this category have poor standing and may be in
                  default. These bonds carry an element of danger with respect
                  to principal and interest payments.

         Ca       Speculative to a high degree and could be in default or have
                  other marked shortcomings. Ca is the lowest rating.


DESCRIPTION OF PREFERRED STOCK RATINGS

MOODY'S

         aaa      Top-quality preferred stock. This rating indicates good asset
                  protection and the least risk of dividend impairment within
                  the universe of preferred stocks.

         aa       High-grade preferred stock. This rating indicates that there
                  is a reasonable assurance the earnings and asset protection
                  will remain relatively well maintained in the foreseeable
                  future.

         a        Upper-medium grade preferred stock. While risks are judged to
                  be somewhat greater than in the "aaa" and "aa" classification,
                  earnings and asset protection are, nevertheless, expected to
                  be maintained at adequate levels.

         baa      Medium-grade preferred stock, neither highly protected nor
                  poorly secured. Earnings and asset protection appear adequate
                  at present but may be questionable over any great length of
                  time.

S&P

S&P's preferred stock rating is an assessment of the capacity and willingness of
an issuer to pay preferred stock dividends and any applicable sinking fund
obligations.

         AAA      Highest rating. This rating indicates an extremely strong
                  capacity to pay the preferred stock obligations.

         AA       High-quality, fixed-income security. The capacity to pay
                  preferred stock obligations is very strong, although not as
                  overwhelming as for issues rated "AAA."

         A        Backed by a sound capacity to pay the preferred stock
                  obligations, although it is somewhat more susceptible to the
                  adverse effects of changes in circumstances and economic
                  conditions.

         BBB      Backed by an adequate capacity to pay the preferred stock
                  obligations. Whereas the issuer normally exhibits adequate
                  protection parameters, adverse economic conditions or changing
                  circumstances are more likely to lead to a weakened capacity
                  to make payments for a preferred stock in this category than
                  for issues in the "A" category.


SHORT-TERM DEBT RATINGS

Thompson Bank Watch, Inc. ("TBW") assigns ratings to specific debt instruments
with original maturities of one year or less. The TBW Short-Term ratings
specifically assess the likelihood of an untimely payment of principal and
interest.

         TBW-1    Very high degree of likelihood that principal and interest
                  will be paid on a timely basis.

         TBW-2    While degree of safety regarding timely repayment of principal
                  and interest is strong, the relative degree is not as high as
                  for issues rated TBW-1.

         TBW-3    Lowest investment grade category. While more susceptible to
                  adverse developments than obligations with higher ratings,
                  capacity to service principal and interest in a timely fashion
                  is considered adequate.

         TBW-4    Non-investment grade and, therefore, speculative.

                                    THE TRUST


         One Group Mutual Funds (the "TRUST") is an open-end management
investment company. The Trust consists of fifty-eight series of units of
beneficial interest ("SHARES") each representing interests in one of fifty-eight
separate investment portfolios ("PORTFOLIOS"). This Statement of Additional
Information provides information about the following four portfolios ("FUNDS"):

         Money Market Funds. The U.S. Government Securities Money Market Fund
         and the Treasury Prime Money Market Fund (these two Funds being
         collectively referred to as the "MONEY MARKET FUNDS"),

         Equity Funds. The Real Estate Fund and the Technology Fund (these two
         Funds being collectively referred to as the "EQUITY FUNDS"),

DIVERSIFICATION. The Money Market Funds are diversified, as defined under the
Investment Company Act of 1940, as amended (the "1940 ACT"). The Real Estate
Fund and Technology Fund are non-diversified.

SHARE CLASSES. Shares in the Funds (other than the Money Market Funds) are
generally offered in four separate classes: Class I Shares, Class A Shares,
Class B Shares and Class C Shares. The U.S. Government Securities Money Market
Fund and the Treasury Prime Money Market Fund offer Class A Shares, Class C
Shares, Class I Shares and Service Class Shares. Much of the information
contained herein expands upon subjects discussed in the Prospectuses for the
respective Funds. No investment in a particular class of Shares of a Fund should
be made without first reading that Fund's Prospectus.

                       INVESTMENT OBJECTIVES AND POLICIES


         The following policies supplement each Fund's investment objective and
policies as set forth in the respective Prospectus for that Fund.

ADDITIONAL INFORMATION ON FUND INSTRUMENTS

ASSET-BACKED SECURITIES

         Asset-backed securities consist of securities secured by company
receivables, home equity loans, truck and auto loans, leases, credit card
receivables and other securities backed by other types of receivables or other
assets. These securities are generally pass-through securities, which means that
principal and interest payments on the underlying securities (less servicing
fees) are passed through to shareholders on a pro rata basis. These securities
involve prepayment risk, which is the risk that the underlying debt may be
refinanced or paid off prior to their maturities during periods of declining
interest rates. In that case, a Fund manager may have to reinvest the proceeds
from the securities at a lower rate. Potential market gains on a security
subject to prepayment risk may be more limited than potential market gains on a
comparable security that is not subject to prepayment risk. Under certain
prepayment rate scenarios, a Fund may fail to recoup any premium paid on
asset-backed securities.

BANK OBLIGATIONS

         Bank obligations consist of bankers' acceptances, certificates of
deposit, and demand and time deposits.

         Bankers' Acceptances are negotiable drafts or bills of exchange
typically drawn by an importer or exporter to pay for specific merchandise,
which are "accepted" by a bank, meaning, in effect, that the bank
unconditionally agrees to pay the face value of the instrument on maturity.
Bankers' acceptances invested in by the Funds will be those guaranteed by
domestic and foreign banks and savings and loan associations having, at the time
of investment, total assets in excess of $1 billion (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
will be those of domestic and foreign branches of U.S. commercial banks which
are members of the Federal Reserve System or the deposits of which are insured
by the Federal Deposit Insurance Corporation, and in certificates of deposit of
domestic savings and loan associations the deposits of which are insured by the
Federal Deposit Insurance Corporation if, at the time of purchase, such
institutions have total assets in excess of $1 billion (as of the date of their
most recently published financial statements). Certificates of deposit may also
include those issued by foreign banks outside the United States with total
assets at the time of purchase in excess of the equivalent of $1 billion. The
Funds may also invest in Eurodollar certificates of deposit, which are U.S.
dollar-denominated certificates of deposit issued by branches of foreign and
domestic banks located outside the United States, and Yankee certificates of
deposit, which are certificates of deposit issued by a U.S. branch of a foreign
bank denominated in U.S. dollars and held in the United States. Certain Funds
may also invest in obligations (including banker's acceptances and certificates
of deposit) denominated in foreign currencies (see "Foreign Investments"
herein).

         Demand Deposits are funds deposited in a commercial bank or a savings
and loan association which, without prior notice to the bank, may be withdrawn
generally by negotiable draft. Time and demand deposits will be maintained only
at banks or savings and loan associations from which a Fund could purchase
certificates of deposit. Time Deposits are interest-bearing non-negotiable
deposits at a bank or a savings and loan association that have a specific
maturity date. A time deposit earns a specific rate of interest over a definite
period of time. Time deposits cannot be traded on the secondary market and those
exceeding seven days and with a withdrawal penalty are considered to be
illiquid.

COMMERCIAL PAPER


                                       2
<PAGE>   114


         Commercial paper consists of promissory notes issued by corporations.
Although such notes are generally unsecured, the Funds may also purchase secured
commercial paper. Except as noted below with respect to variable amount master
demand notes, issues of commercial paper normally have maturities of less than
nine months and fixed rates of return. The Funds only purchase commercial paper
that meets the following criteria.

         Equity Funds. The Equity Funds may purchase commercial paper consisting
         of issues rated at the time of purchase in the highest or second
         highest rating category by at least one NRSRO (such as A-2 or better by
         S&P, P-2 or better by Moody's or F-2 or better by Fitch) or if unrated,
         determined by Banc One Investment Advisors to be of comparable quality.

COMMON STOCK

         Common stock represents a share of ownership in a company and usually
carries voting rights and earns dividends. Unlike preferred stock, dividends on
common stock are not fixed but are declared at the discretion of the issuer's
board of directors.

CONVERTIBLE SECURITIES

         Convertible securities have characteristics similar to both fixed
income and equity securities. Convertible securities may be issued as bonds or
preferred stock. Because of the conversion feature, the market value of
convertible securities tends to move together with the market value of the
underlying stock. As a result, the Funds' selection of convertible securities is
based, to a great extent, on the potential for capital appreciation that may
exist in the underlying stock. The value of convertible securities is also
affected by prevailing interest rates, the credit quality of the issuer, and any
call provisions.

FOREIGN INVESTMENTS

         Some of the Funds may invest in certain obligations or securities of
foreign issuers. Possible investments include equity securities of foreign
entities, obligations of foreign branches of U.S. banks and of foreign banks,
including, without limitation, Eurodollar Certificates of Deposit, Eurodollar
Time Deposits, Eurodollar Banker's Acceptances, Canadian Time Deposits and
Yankee Certificates of Deposits, and investments in Canadian Commercial Paper,
and Europaper. Securities of foreign issuers may include sponsored and
unsponsored American Depository Receipts ("ADRs"). Sponsored ADRs are listed on
the New York Stock Exchange; unsponsored ADRs are not. Therefore, there may be
less information available about the issuers of unsponsored ADRs than the
issuers of sponsored ADRs. Unsponsored ADRs are restricted securities.

         RISK FACTORS OF FOREIGN INVESTMENTS

         Political and Exchange Risks. Foreign investments may subject a Fund to
         investment risks that differ in some respects from those related to
         investments in obligations of U.S. domestic issuers. Such risks include
         future adverse political and economic developments, the possible
         imposition of withholding taxes on interest or other income, possible
         seizure, nationalization or expropriation of foreign deposits, the
         possible establishment of exchange controls or taxation at the source,
         greater fluctuations in value due to changes in exchange rates, or the
         adoption of other foreign governmental restrictions which might
         adversely affect the payment of principal and interest on such
         obligations.

         Higher Transaction Costs. Foreign investments may entail higher
         custodial fees and sales commissions than domestic investments.

         Accounting and Regulatory Differences. Foreign issuers of securities or
         obligations are often subject to accounting treatment and engage in
         business practices different from those respecting domestic issuers of
         similar securities or obligations. Foreign branches of U.S. banks and
         foreign banks are not regulated by U.S. banking authorities and may be
         subject to less stringent reserve requirements than those applicable to



                                       3
<PAGE>   115


         domestic branches of U.S. banks. In addition, foreign banks generally
         are not bound by the accounting, auditing, and financial reporting
         standards comparable to those applicable to U.S. banks.

         Currency Risk. On January 1, 1999, the European Economic and Monetary
         Union introduced the "euro." The euro will serve as a common currency
         for participating European nations. All stocks issued by corporations
         located in those nations will be denominated in euros. In addition,
         outstanding shares have been redenominated in euros. All government
         bonds issued by participating nations will be in euros, and outstanding
         government bonds have been redenominated in euros. The introduction of
         the euro presents some uncertainties, such as the adequacy of newly
         created accounting, clearing, settlement, and payment systems for the
         new currency. These uncertainties could adversely affect the value of
         the foreign securities held by the Funds.

         LIMITATIONS ON THE USE OF FOREIGN INVESTMENTS . Investments in all
types of foreign obligations or securities will not exceed 25% of the net assets
of the Funds that may invest in such securities.

FUTURES AND OPTIONS TRADING

         Some of the Funds may enter into futures contracts, options, options on
futures contracts and stock index futures contracts and options thereon for the
purposes of remaining fully invested, reducing transaction costs, or managing
interest rate risk.

         FUTURES CONTRACTS

         Futures contracts provide for the future sale by one party and purchase
by another party of a specified amount of a specific security, class of
securities, or an index at a specified future time and at a specified price. A
stock index futures contract is a bilateral agreement pursuant to which two
parties agree to take or make delivery of an amount of cash equal to a specified
dollar amount times the difference between the stock index value at the close of
trading of the contracts and the price at which the futures contract is
originally struck. Futures contracts which are standardized as to maturity date
and underlying financial instrument are traded on national futures exchanges.
Futures exchanges and trading are regulated under the Commodity Exchange Act by
the Commodity Futures Trading Commission ("CFTC"), a U.S. government agency.

         Although most futures contracts by their terms call for actual delivery
and acceptance of the underlying securities, in most cases the contracts are
closed out before the settlement date without the making or taking of delivery.
Closing out an open futures position is done by taking an opposite position
("buying" a contract which has previously been "sold," or "selling" a contract
previously "purchased") in an identical contract to terminate the position. 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. Brokerage commissions are incurred when a
futures contract is bought or sold.

         When making futures trades, the Funds are required to make a good faith
margin deposit in cash or government securities with a broker or custodian to
initiate and maintain open positions in futures contracts. A margin deposit is
intended to assure completion of the contract (delivery or acceptance of the
underlying security) if it is not terminated prior to the specified delivery
date. Minimal initial margin requirements are established by the futures
exchange and may be changed. Brokers may establish deposit requirements which
are higher than the exchange minimums. Initial margin deposits on futures
contracts are customarily set at levels much lower than the prices at which the
underlying securities are purchased and sold, typically ranging upward from less
than 5% of the value of the contract being traded.

         After a futures contract position is opened, the value of the contract
is marked to market daily. If the futures contract price changes to the extent
that the margin on deposit does not satisfy margin requirements, payment of
additional "variation" margin will be required. Conversely, change in the
contract value may reduce the required margin, resulting in a repayment of
excess margin to the contract holder. Variation margin payments are made to 



                                       4

and from the futures broker for as long as the contract remains open. The Funds
expect to earn interest income on their margin deposits.

         Traders in futures contracts may be broadly classified as either
"hedgers" or "speculators." Hedgers use the futures markets primarily to offset
unfavorable changes in the value of securities otherwise held for investment
purposes or expected to be acquired by them. Speculators are less inclined to
own the securities underlying the futures contracts which they trade, and use
futures contracts with the expectation of realizing profits from fluctuations in
the prices of underlying securities. The Funds intend to enter into futures
contracts, options on futures contracts, index futures and options thereon that
are traded on an exchange regulated by the CFTC if, to the extent that such
futures and options are not for "bona fide hedging purposes" (as defined by the
CFTC), the aggregate initial margin and premiums on such positions (excluding
the amount by which options are in the money) do not exceed 5% of the Fund's
total assets at current value. A Fund, however, may invest more than such amount
for bona fide hedging purposes, and also may invest more than such amount if it
obtains authority to do so from the CFTC without rendering the fund a commodity
pool operator or adversely affecting its status as an investment company for
federal securities laws.

         A Fund may buy and sell futures contracts and related options to manage
its exposure to changing interest rates and security prices. 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.

         Although techniques other than the sale and purchase of futures
contracts could be used to control the Funds' exposure to market fluctuations,
the use of futures contracts may be a more effective means of managing this
exposure. While the Funds will incur commission expenses in both opening and
closing out futures positions, these costs may be lower than transaction costs
that would be incurred in the purchase and sale of the underlying securities.

         A Fund's ability to effectively utilize futures trading depends on
several factors. First, it is possible that there will not be a perfect price
correlation between the futures contracts and their underlying reference
security or index. Second, it is possible that a lack of liquidity for futures
contracts could exist in the secondary market, resulting in an inability to
close a futures position prior to its maturity date. Third, the purchase of a
futures contract involves the risk that a Fund could lose more than the original
margin deposit required to initiate a futures transaction.

         LIMITATIONS ON THE USE OF FUTURES CONTRACTS

         None of the Funds will enter into futures contract transactions for
purposes other than bona fide hedging purposes to the extent that, immediately
thereafter, the sum of its initial margin deposits and premiums on open
contracts exceeds 5% of the market value of the respective Fund's total assets.
In addition, none of the Equity Funds will enter into futures contracts to the
extent that the value of the futures contracts held would exceed 25% of the
respective Fund's total assets.

         The Funds have undertaken to restrict their futures contract trading as
follows: first, the Funds will not engage in transactions in futures contracts
for speculative purposes; second, the Funds will not market themselves to the
public as commodity pools or otherwise as vehicles for trading in the
commodities futures or commodity options markets; third, the Funds will disclose
to all prospective Shareholders the purpose of and limitations on their
commodity futures trading; fourth, the Funds will submit to the CFTC special
calls for information. Accordingly, registration as a commodities pool operator
with the CFTC is not required.

         In addition to the margin restrictions discussed above, transactions in
futures contracts may involve the segregation of funds pursuant to requirements
imposed by the SEC. Under those requirements, where a Fund has a 



                                       5
<PAGE>   117


long position in a futures contract, it may be required to establish a
segregated account (not with a futures commission merchant or broker) containing
cash or certain liquid assets equal to the purchase price of the contract (less
any margin on deposit). For a short position in futures or forward contracts
held by a Fund, those requirements may mandate the establishment of a segregated
account (not with a futures commission merchant or broker) with cash or certain
liquid assets that, when added to the amounts deposited as margin, equal the
market value of the instruments underlying the futures contracts (but are not
less than the price at which the short positions were established). However,
segregation of assets is not required if a Fund "covers" a long position. For
example, instead of segregating assets, a Fund, when holding a long position in
a futures contract, could purchase a put option on the same futures contract
with a strike price as high or higher than the price of the contract held by the
Fund. In addition, where a Fund takes short positions, or engages in sales of
call options, it need not segregate assets if it "covers" these positions. For
example, where a Fund holds a short position in a futures contract, it may cover
by owning the instruments underlying the contract. The Funds may also cover such
a position by holding a call option permitting it to purchase the same futures
contract at a price no higher than the price at which the short position was
established. Where a Fund sells a call option on a futures contract, it may
cover either by entering into a long position in the same contract at a price no
higher than the strike price of the call option or by owning the instruments
underlying the futures contract. A Fund could also cover this position by
holding a separate call option permitting it to purchase the same futures
contract at a price no higher than the strike price of the call option sold by
the Fund. In certain circumstances, entry into a futures contract that
substantially eliminates risk of loss and the opportunity for gain in an
"appreciated financial position" will also accelerate gain to the Funds.

         RISK FACTORS IN FUTURES TRANSACTIONS

         Liquidity. Positions in futures contracts may be closed out only on an
         exchange which provides a secondary market for such futures. However,
         there can be no assurance that a liquid secondary market will exist for
         any particular futures contract at any specific time. Thus, it may not
         be possible to close a futures position. In the event of adverse price
         movements, a Fund would continue to be required to make daily cash
         payments to maintain the required margin. In such situations, if a Fund
         has insufficient cash, it may have to sell portfolio securities to meet
         daily margin requirements at a time when it may be disadvantageous to
         do so. In addition, a Fund may be required to make delivery of the
         instruments underlying futures contracts it holds. The inability to
         close options and futures positions also could have an adverse impact
         on the ability to effectively hedge such positions. The Funds will
         minimize the risk that they will be unable to close out a futures
         contract by only entering into futures contracts which are traded on
         national futures exchanges and for which there appears to be a liquid
         secondary market.

         Risk of Loss. The risk of loss in trading futures contracts in some
         strategies can be substantial, due both to the low margin deposits
         required, and the extremely high degree of leverage involved in futures
         pricing. Because the deposit requirements in the futures markets are
         less onerous than margin requirements in the securities market, there
         may be increased participation by speculators in the futures market
         which may also cause temporary price distortions. A relatively small
         price movement in a futures contract may result in immediate and
         substantial loss (as well as gain) to the investor. For example, if at
         the time of purchase, 10% of the value of the futures contract is
         deposited as margin, a subsequent 10% decrease in the value of the
         futures contract would result in a total loss of the margin deposit,
         before any deduction for the transaction costs, if the account were
         then closed out. A 15% decrease would result in a loss equal to 150% of
         the original margin deposit if the contract were closed out. Thus, a
         purchase or sale of a futures contract may result in losses in excess
         of the amount invested in the contract. However, because the futures
         strategies engaged in by the Funds are only for risk management
         purposes, Banc One Investment Advisors does not believe that the Funds
         are subject to the risks of loss frequently associated with futures
         transactions. Each Fund would presumably have sustained comparable
         losses if, instead of the futures contract, it had invested in the
         underlying financial instrument and sold it after the decline.




                                       6
<PAGE>   118


         Correlation Risk. Utilization of futures transactions by a Fund
         involves the risk of imperfect or no correlation where the securities
         underlying futures contracts have different maturities than the
         portfolio securities being hedged. It is also possible that a Fund
         could lose money on futures contracts and also experience a decline in
         value of its portfolio securities. There is also the risk of loss by a
         Fund of margin deposits in the event of bankruptcy of a broker with
         whom the Fund has an open position in a futures contract or related
         option.

         Price Fluctuations. Most futures exchanges limit the amount of
         fluctuation permitted in futures contract prices during a single
         trading day. The daily limit establishes the maximum amount that the
         price of a futures contract may vary either up or down from the
         previous day's settlement price at the end of a trading session. Once
         the daily limit has been reached in a particular type of contract, no
         trades may be made on that day at a price beyond that limit. The daily
         limit governs only price movement during a particular trading day and
         therefore does not limit potential losses, because the limit may
         prevent the liquidation of unfavorable positions. Futures contract
         prices have occasionally moved to the daily limit for several
         consecutive trading days with little or no trading, thereby preventing
         prompt liquidation of futures positions and subjecting some futures
         traders to substantial losses.

         Some futures strategies, including selling futures, buying puts and
writing covered calls, may reduce a Fund's exposure to price fluctuations. Other
strategies, including buying futures, and buying calls, tend to increase market
exposure. Futures and options may be combined with each other in order to adjust
the risk and return characteristics of the overall portfolio. A Fund expects to
enter into these transactions to manage a return or spread on a particular
investment or portion of its assets, to protect against any increase in the
price of securities a Fund anticipates purchasing at a later date, or for other
risk management strategies.

         OPTIONS CONTRACTS

         Some of the Funds may use options on securities or futures contracts as
a hedging device. An option gives the buyer of the option the right (but not the
obligation) to purchase a futures contract or security at a specified price
(also called the STRIKE price). A CALL OPTION gives the buyer the "right to
purchase" a security at a specified price (the exercise price) at any time until
a certain date (the expiration date). So long as the obligation of the writer of
a call option continues, the writer may be assigned an exercise notice by the
broker-dealer through whom such option was sold, requiring the writer to deliver
the underlying security against payment of the exercise price. This obligation
terminates upon the expiration of the call option, or such earlier time at which
the writer effects a closing purchase transaction by repurchasing an option
identical to that previously sold. To secure the writer's obligation to deliver
the underlying security in the case of a call option, subject to the rules of
the Options Clearing Corporation, a writer is required to deposit in escrow the
underlying security or other assets in accordance with such rules.

         A PUT OPTION gives the buyer the right to sell the underlying futures
contract or security. The purchase price of an option is referred to as its
"premium." The seller (or "writer") of a put option must purchase futures
contracts or securities at a strike price if the option is exercised. In the
case of a call option, the seller must sell the futures contract or security in
the underlying futures contract or security at the strike price if the option is
exercised.

         A NAKED OPTION is an option written by a party who does not own the
underlying futures contract or security. A COVERED OPTION is an option written
by a party who does own the underlying position. The initial purchase (sale) of
an option is an "opening transaction." In order to close out an option position,
the Fund may enter into a "closing transaction". This involves the sale
(purchase) of an option contract on the same security with the same exercise
price and expiration date as the option contract originally opened. A call
option on a futures contract or security is said to be "in-the-money" if the
strike price is below current market levels and "out-of-the-money" if the strike
price is above current market levels. A put option is "in-the-money" if the
strike price is above current market levels, and "out-of-the-money" if the
strike price is below current market levels.

         Options have limited life spans, usually tied to the delivery or
settlement date of the underlying futures contract or security. Some options,
however, expire significantly in advance of such dates. An option that is
"out-of-the-money" and not offset by the time it expires becomes worthless. On
certain exchanges "in-the-money" 



                                       7
<PAGE>   119


options are automatically exercised on their expiration date, but on others
unexercised options simply become worthless after their expiration date. Options
usually trade at a premium (referred to as the "time value" of the option) above
their intrinsic value (the difference between the market price for the
underlying futures contract or equity security and the strike price). As an
option nears its expiration date, the market value and the intrinsic value move
into parity as the time value diminishes.

         Increased market volatility generally increases the value of options by
increasing the probability of favorable market swings, putting outstanding
options "in-the-money." Although purchasing options is a limited risk trading
approach, significant losses can be incurred by doing so.

         WRITING (SELLING) COVERED CALLS

         Some of the Funds may write (sell) covered call options and purchase
options to close out options previously written by the Fund. The Funds' purpose
in writing covered call options is to generate additional premium income. This
premium income will serve to enhance a Fund's total return and will reduce the
effect of any price decline of the security involved in the option. Generally,
the Funds will write covered call options on securities which, in the opinion of
Banc One Investment Advisors, are not expected to make any major price moves in
the near future but which, over the long term, are deemed to be attractive
investments for the Fund. The Funds will write only covered call options. This
means that a Fund will only write a call option on a security which a Fund
already owns.

         Fund securities on which call options may be written will be purchased
solely on the basis of investment considerations consistent with each Fund's
investment objectives. The writing of covered call options is a conservative
investment technique believed to involve relatively little risk (in contrast to
the writing of naked options, which a Fund will not do), but capable of
enhancing the Fund's total return. When writing a covered call option, a Fund,
in return for the premium, gives up the opportunity for profit from a price
increase in the underlying security above the exercise price, but conversely
retains the risk of loss should the price of the security decline. Unlike one
who owns securities not subject to an option, a Fund has no control over when it
may be required to sell the underlying securities, since it may be assigned an
exercise notice at any time prior to the expiration of its obligation as a
writer. Thus, the security could be "called away" at a price substantially below
the fair market value of the security. If a call option which a Fund has written
expires, a Fund will realize a gain in the amount of the premium; however, such
gain may be offset by a decline in the market value of the underlying security
during the option period. If the call option is exercised, a Fund will realize a
gain or loss from the sale of the underlying security. The security covering the
call will be maintained in a segregated account of the Fund's custodian. The
Funds do not consider a security covered by a call to be "pledged" as that term
is used in each Fund's policy which limits the pledging or mortgaging of its
assets.

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

         Generally, a Fund, in order to avoid the exercise of an option sold by
it, will be able to cancel its obligation under the option by entering into a
closing purchase transaction, if available, unless selling (in the case of a
call option) or purchasing (in the case of a put option) the underlying
securities is determined to be in a Fund's best interest. A closing purchase
transaction consists of a Fund purchasing an option having the same terms as the
option 



                                       8
<PAGE>   120


sold by a Fund, and has the effect of cancelling a Fund's position as a seller.
The premium which a Fund will pay in executing a closing purchase transaction
may be higher (or lower) than the premium received when the option was sold,
depending in large part upon the relative price of the underlying security at
the time of each transaction. To the extent options sold by a Fund are exercised
and a Fund delivers securities to the holder of a call option, a Fund's turnover
rate will increase, which would cause a Fund to incur additional brokerage
expenses.

         Closing transactions will be effected in order to realize a profit on
an outstanding call option, to prevent an underlying security from being called,
or to permit the sale of the underlying security.

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

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

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

         PURCHASING CALL OPTIONS

         Certain Funds may purchase call options to hedge against an increase in
the price of securities that the Fund wants ultimately to buy. Such hedge
protection is provided during the life of the call option since the Fund, as
holder of the call option, is able to buy the underlying security at the
exercise price regardless of any increase in the underlying security's market
price. In order for a call option to be profitable, the market price of the
underlying security must rise sufficiently above the exercise price to cover the
premium and transaction costs. These costs will reduce any profit the Fund might
have realized had it bought the underlying security at the time it purchased the
call option. In the event that paying a premium for a call option, together with
a price movement in the underlying security, is such that exercise of the option
would not be profitable to the Fund, loss of the premium may be offset by a
decrease in the acquisition cost of securities by the Fund.

         PURCHASING PUT OPTIONS

         Certain Funds may also purchase put options to protect their portfolio
holdings in an underlying security against a decline in market value. Such hedge
protection is provided during the life of the put option since the Fund, as
holder of the put option, is able to sell the underlying security at the put
exercise price regardless of any decline in the underlying security's market
price. For a put option to be profitable, the market price of the underlying
security must decline sufficiently below the exercise price to cover the premium
and transaction costs. By using put options in this manner, the Fund will reduce
any profit it might otherwise have realized from appreciation of the underlying
security by the premium paid for the put option and by transaction cost.
However, any loss of premium may be offset by an increase in the value of the
Fund's securities.

<PAGE>   121


         WRITING (SELLING) SECURED PUTS

         Certain Funds may write secured puts. For the secured put writer,
substantial depreciation in the value of the underlying security would result in
the security being "put to" the writer at the strike price of the option which
may be substantially in excess of the fair market value of the security. If a
secured put option expires unexercised, the writer realizes a gain in the amount
of the premium.

         STRADDLES AND SPREADS

         Certain Funds also may engage in straddles and spreads. In a straddle
transaction, a Fund either buys a call and a put or sells a call and a put on
the same security. In a spread, the Fund purchases and sells a call or a put.
The Fund will sell a straddle when Banc One Investment Advisors believes the
price of a security will be stable. The Fund will receive a premium on the sale
of the put and the call. A spread permits the Fund to make a hedged investment
that the price of a security will increase or decline.

         RISK FACTORS IN OPTIONS TRANSACTIONS

         Risk of Loss. When it purchases an option, a Fund runs the risk that it
will lose its entire investment in the option in a relatively short period of
time, unless the Fund exercises the option or enters into a closing sale
transaction with respect to the option during the life of the option. If the
price of the underlying security does not rise (in the case of a call) or fall
(in the case of a put) to an extent sufficient to cover the option premium and
transaction costs, a Fund will lose part or all of its investment in the option.
This contrasts with an investment by a Fund in the underlying securities, since
the Fund may continue to hold its investment in those securities notwithstanding
the lack of a change in price of those securities. In addition, there may be
imperfect or no correlation between the changes in market value of the
securities held by the Funds and the prices of the options.

         Judgement of Advisor. The successful use of the options strategies
depends on the ability of Banc One Investment Advisors to assess interest rate
and market movements correctly and to accurately calculate the fair price of the
option. The effective use of options also depends on a Fund's ability to
terminate option positions at times when Banc One Investment Advisors, deems it
desirable to do so. A Fund will take an option position only if Banc One
Investment Advisors believes there is a liquid secondary market for the option,
however, there is no assurance that a Fund will be able to effect closing
transactions at any particular time or at an acceptable price.

         Liquidity. If a secondary trading market in options were to become
unavailable, a Fund could no longer engage in closing transactions. Lack of
investor interest might adversely affect the liquidity of the market for
particular options or series of options. A marketplace may discontinue trading
of a particular option or options generally. In addition, a market could become
temporarily unavailable if unusual events, such as volume in excess of trading
or clearing capability, were to interrupt normal market operations. A
marketplace may at times find it necessary to impose restrictions on particular
types of options transactions, which may limit a Fund's ability to realize its
profits or limit its losses.

         Market Restrictions. Disruptions in the markets for the securities
underlying options purchased or sold by a Fund could result in losses on the
options. If trading is interrupted in an underlying security, the trading of
options on that security is normally halted as well. As a result, a Fund as
purchaser or writer of an option will be unable to close out its positions until
option trading resumes, and it may be faced with losses if trading in the
security reopens at a substantially different price. In addition, the Options
Clearing Corporation ("OCC") or other options markets may impose exercise
restrictions. If a prohibition on exercise is imposed at the time when trading
in the option has also been halted, a Fund as purchaser or writer of an option
will be locked into its position until one of the two restrictions has been
lifted. If a prohibition on exercise remains in effect until an option owned by
a Fund has expired, the Fund could lose the entire value of its option.

         Foreign Investment Risks. Special risks are presented by
internationally-traded options. Because of time differences between the United
States and the various foreign countries, and because different holidays are
observed in different countries, foreign option markets may be open for trading
during hours or on days when U.S. markets 



                                       10
<PAGE>   122


are closed. As a result, option premiums may not reflect the current prices of
the underlying interest in the United States.

         LIMITATIONS ON THE USE OF OPTIONS

         Each Fund will limit the writing of put and call options to 25% of its
net assets. Some Funds may enter into over-the-counter option transactions.
There will be an active over-the-counter market for such options which will
establish their pricing and liquidity. Broker/Dealers with whom the Trust will
enter into such option transactions shall have a minimum net worth of
$20,000,000.

GOVERNMENT SECURITIES

         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, are supported by the full faith and credit of the
U.S. Treasury; others, such as the Federal National Mortgage Association
("FANNIE MAE"), 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, such as the
Federal Farm Credit Banks and the Federal Home Loan Mortgage Corporation
("FREDDIE MAC") are supported only by the credit of the instrumentality. No
assurance can be given that the U.S. government would provide financial support
to U.S. government-sponsored agencies or instrumentalities if it is not
obligated to do so by law. A Fund will invest in the obligations of such
agencies or instrumentalities only when Banc One Investment Advisors believes
that the credit risk with respect thereto is minimal. For information on
mortgage-related securities issued by certain agencies or instrumentalities of
the U.S. government, see "Investment Objectives and Policies--Mortgage-Related
Securities" in this Statement of Additional Information.

HIGH QUALITY INVESTMENTS WITH REGARD TO THE MONEY MARKET FUNDS

         The Money Market Funds may invest only in obligations determined by the
Fund's investment Advisor, Banc One Investment Advisors to present minimal
credit risks under guidelines adopted by the Trust's Board of Trustees.

         The Treasury Prime Money Market Fund may only invest in U.S. Treasury
bills, notes and other U.S. Treasury obligations issued or guaranteed by the 
U.S. government.

         The U.S. Government Securities Money Market Fund invest exclusively in
securities issued or guaranteed by the U.S. government or its agencies or
instrumentalities, some of which may be subject to repurchase agreements.

         With regard to the Money Market Funds, investments will be limited to
those obligations which, at the time of purchase, (i) possess one of the three
highest short-term ratings from an NRSRO in the case of single-rated securities;
or (ii) possess, in the case of multiple-rated securities, one of the three
highest short-term ratings by at least two NRSROs or (iii) do not possess a
rating (i.e., are unrated) but are determined by Banc One Investment Advisors to
be of comparable quality to the rated instruments eligible for purchase by the
Trust under guidelines adopted by the Board of Trustees (collectively, "ELIGIBLE
SECURITIES"). A security that has not received a rating will be deemed to
possess the rating assigned to an outstanding class of the issuer's short-term
debt obligations if determined by Banc One Investment Advisors to be comparable
in priority and security to the obligation selected for purchase by the Trust.

         A security subject to a tender or demand feature will be considered an
Eligible Security only if both the demand feature and the underlying security
possess a high quality rating or, if such do not possess a rating, are
determined by Banc One Investment Advisors to be of comparable quality;
provided, however, that where the demand feature would be readily exercisable in
the event of a default in payment of principal or interest on the underlying
security, the obligation may be acquired based on the rating possessed by the
demand feature or, if the demand feature does not possess a rating, a
determination of comparable quality by Banc One Investment Advisors. A security
which at the time of issuance had a maturity exceeding 397 days but, at the time
of purchase, has a 



                                       11
<PAGE>   123


remaining maturity of 397 days or less, is not considered an Eligible Security
if it does not possess a high quality rating and the long-term rating, if any,
is not within the top three highest rating categories.

         Eligible Securities include First-Tier Securities and Second-Tier
Securities. First-Tier Securities include those that possess a rating in the
highest category, in the case of a single-rated security, or at least two
ratings in the highest rating category, in the case of multiple-rated
securities, or, if the securities do not possess a rating, are determined to be
of comparable quality by Banc One Investment Advisors pursuant to the guidelines
adopted by the Board of Trustees. Second-Tier Securities are all other Eligible
Securities.

         Each Money Market Fund will not invest more than 5% of its total assets
in the First Tier Securities of any one issuer (as defined by or permitted under
Rule 2a-7). In addition, each Fund may not invest more than 5% of its total
assets in Second Tier Securities, with investment in the Second Tier Securities
of any one issuer further limited to the greater of 1% of the Fund's total
assets or $1 million. If a percentage limitation is satisfied at the time of
purchase, a later increase in such percentage resulting from a change in the
Fund's net asset value or a subsequent change in a security's qualification as a
First Tier or Second Tier Security will not constitute a violation of the
limitation. In addition, there is no limit on the percentage of a Fund's assets
that may be invested in obligations issued or guaranteed by the U.S. government,
its agencies, or instrumentalities and, with respect to each Money Market Fund
(other than the Treasury Prime Money Market Fund), repurchase agreements fully
collateralized by such obligations.

         Under the guidelines adopted by the Trust's Board of Trustees and in
accordance with Rule 2a-7 under the 1940 Act, Banc One Investment Advisors may
be required to promptly dispose of an obligation held in a Fund's portfolio in
the event of certain developments that indicate a diminishment of the
instrument's credit quality, such as where an NRSRO downgrades an obligation
below the second highest rating category, or in the event of a default relating
to the financial condition of the issuer.

         A rating by an NRSRO may be utilized only where the NRSRO is neither
controlling, controlled by, or under common control with the issuer of, or any
issuer, guarantor, or provider of credit support for, the instrument.

INVESTMENT COMPANY SECURITIES

         Some of the Funds may invest up to 5% of their total assets in the
securities of any one investment company (another mutual fund), but may not own
more than 3% of the outstanding securities of any one investment company or
invest more than 10% of their total assets in the securities of other investment
companies. Other investment company securities may include securities of a money
market fund of the Trust, and securities of other investment companies for which
Banc One Investment Advisors serves as investment advisor or administrator.
Because other investment companies employ an investment advisor, such
investments by the Funds may cause Shareholders to bear duplicate fees. Banc One
Investment Advisors will waive its fee attributable to the assets of the
investing fund invested in a money market fund of the Trust and in other funds
advised by Banc One Investment Advisors; and, to the extent required by the laws
of any state in which shares of the Trust are sold, Banc One Investment Advisors
will waive its fees attributable to the assets of any Fund invested in any
investment company.

MORTGAGE-RELATED SECURITIES

         MORTGAGE-BACKED SECURITIES (CMOS AND REMICS). Certain of the Funds may
invest in mortgage-backed securities including collateralized mortgage
obligations ("CMOS") and Real Estate Mortgage Investment Conduits ("REMICS").
Mortgage-backed securities represent pools of mortgage loans assembled for sale
to investors by various governmental agencies such as Ginnie Mae and
government-related organizations such as Fannie Mae and Freddie Mac, as well as
by nongovernmental issuers such as commercial banks, savings and loan
institutions, mortgage bankers, and private mortgage insurance companies. Such
non-governmental mortgage securities cannot be treated as U.S. government
securities for purposes of investment policies. A REMIC is a CMO that qualifies
for special tax treatment under the Code and invests in certain mortgages
principally secured by interests in real property and other permitted
investments.


                                       12
<PAGE>   124


         There are a number of important differences among the agencies and
instrumentalities of the U.S. government that issue mortgage-related securities
and among the securities that they issue.

         Ginnie Mae Securities. Mortgage-related securities issued by Ginnie Mae
include Ginnie Mae Mortgage Pass-Through Certificates which are guaranteed as to
the timely payment of principal and interest by Ginnie Mae and such guarantee is
backed by the full faith and credit of the United States. Ginnie Mae is a
wholly-owned U.S. government corporation within the Department of Housing and
Urban Development. Ginnie Mae certificates also are supported by the authority
of Ginnie Mae to borrow funds from the U.S. Treasury to make payments under its
guarantee.

         Fannie Mae Securities. Mortgage-related securities issued by Fannie Mae
include Fannie Mae Guaranteed Mortgage Pass-Through Certificates which are
solely the obligations of Fannie Mae and are not backed by or entitled to the
full faith and credit of the United States. Fannie Mae is a government-sponsored
organization owned entirely by private stock-holders. Fannie Mae Certificates
are guaranteed as to timely payment of the principal and interest by Fannie Mae.

         Freddie Mac Securities. Mortgage-related securities issued by Freddie
Mac include Freddie Mac Mortgage Participation Certificates. Freddie Mac is a
corporate instrumentality of the United States, created pursuant to an Act of
Congress, which is owned entirely by Federal Home Loan Banks.

         Freddie Mac Certificates are not guaranteed by the United States or by
any Federal Home Loan Banks and do not constitute a debt or obligation of the
United States or of any Federal Home Loan Bank. Freddie Mac Certificates entitle
the holder to timely payment of interest, which is guaranteed by Freddie Mac.
Freddie Mac guarantees either ultimate collection or timely payment of all
principal payments on the underlying mortgage loans. When Freddie Mac does not
guarantee timely payment of principal, Freddie Mac may remit the amount due on
account of its guarantee of ultimate payment of principal at any time after
default on an underlying mortgage, but in no event later than one year after it
becomes payable.

         CMOs and guaranteed REMIC pass-through certificates ("REMIC
CERTIFICATES") issued by Fannie Mae, Freddie Mac, Ginnie Mae and private issuers
are types of multiple class pass-through securities. Investors may purchase
beneficial interests in REMICs, which are known as "regular" interests or
"residual" interests. The Funds do not currently intend to purchase residual
interests in REMICs. The REMIC Certificates represent beneficial ownership
interests in a REMIC Trust, generally consisting of mortgage loans or Fannie
Mae, Freddie Mac or Ginnie Mae guaranteed mortgage pass-through certificates
(the "MORTGAGE ASSETS"). The obligations of Fannie Mae, Freddie Mac or Ginnie
Mae under their respective guaranty of the REMIC Certificates are obligations
solely of Fannie Mae, Freddie Mac or Ginnie Mae, respectively.

         Fannie Mae REMIC Certificates are issued and guaranteed as to timely
distribution of principal and interest by Fannie Mae. In addition, Fannie Mae
will be obligated to distribute the principal balance of each class of REMIC
Certificates in full, whether or not sufficient funds are otherwise available.

         For Freddie Mac REMIC Certificates, Freddie Mac guarantees the timely
payment of interest, and also guarantees the payment of principal as payments
are required to be made on the underlying mortgage participation certificates
("PCs"). PCs represent undivided interests in specified residential mortgages or
participation therein purchased by Freddie Mac and placed in a PC pool. With
respect to principal payments on PCs, Freddie Mac generally guarantees ultimate
collection of all principal of the related mortgage loans without offset or
deduction. Freddie Mac also guarantees timely payment of principal on certain
PCs referred to as "Gold PCs."

         Ginnie Mae REMIC Certificates guarantee the full and timely payment of
interest and principal on each class of securities (in accordance with the terms
of those classes as specified in the related offering circular supplement). The
Ginnie Mae guarantee is backed by the full faith and credit of the United States
of America.


         REMIC Certificates issued by Fannie Mae, Freddie Mac and Ginnie Mae are
treated as U.S. government 



                                       13
<PAGE>   125


securities for purposes of investment policies. CMOs and REMIC Certificates
provide for the redistribution of cash flow to multiple classes. Each class of
CMOs or REMIC Certificates, often referred to as a "tranches," is issued at a
specific adjustable or fixed interest rate and must be fully retired no later
than its final distribution date. This reallocation of interest and principal
results in the redistribution of prepayment risk across to different classes.
This allows for the creation of bonds with more or less risk than the underlying
collateral exhibits. Principal prepayments on the mortgage loans or the Mortgage
Assets underlying the CMOs or REMIC Certificates may cause some or all of the
classes of CMOs or REMIC Certificates to be retired substantially earlier than
their final distribution dates. Generally, interest is paid or accrues on all
classes of CMOs or REMIC Certificates on a monthly basis.

         The principal of and interest on the Mortgage Assets may be allocated
among the several classes of CMOs or REMIC Certificates in various ways. In
certain structures (known as "sequential pay" CMOs or REMIC Certificates),
payments of principal, including any principal prepayments, on the Mortgage
Assets generally are applied to the classes of CMOs or REMIC Certificates in the
order of their respective final distribution dates. Thus, no payment of
principal will be made on any class of sequential pay CMOs or REMIC Certificates
until all other classes having an earlier final distribution date have been paid
in full.

         Additional structures of CMOs and REMIC Certificates include, among
others, "parallel pay" CMOs and REMIC Certificates. Parallel pay CMOs or REMIC
Certificates are those which are structured to apply principal payments and
prepayments of the Mortgage Assets to two or more classes concurrently on a
proportionate or disproportionate basis. These simultaneous payments are taken
into account in calculating the final distribution date of each class.

         A wide variety of REMIC Certificates may be issued in the parallel pay
or sequential pay structures. These securities include accrual certificates
(also known as "Z-BONDS"), which only accrue interest at a specified rate until
all other certificates having an earlier final distribution date have been
retired and are converted thereafter to an interest-paying security, and planned
amortization class ("PAC") certificates, which are parallel pay REMIC
Certificates which generally require that specified amounts of principal be
applied on each payment date to one or more classes of REMIC Certificates (the
"PAC CERTIFICATES"), even though all other principal payments and prepayments of
the Mortgage Assets are then required to be applied to one or more other classes
of the certificates. The scheduled principal payments for the PAC Certificates
generally have the highest priority on each payment date after interest due has
been paid to all classes entitled to receive interest currently. Shortfalls, if
any, are added to the amount of principal payable on the next payment date. The
PAC Certificate payment schedule is taken into account in calculating the final
distribution date of each class of PAC. In order to create PAC tranches, one or
more tranches generally must be created that absorb most of the volatility in
the underlying Mortgage Assets. These tranches tend to have market prices and
yields that are much more volatile than the PAC classes. The Z-Bonds in which
the Funds may invest may bear the same non-credit- related risks as do other
types of Z-Bonds. Z-Bonds in which the Fund may invest will not include residual
interest.

         LIMITATIONS ON THE USE OF MORTGAGE-BACKED SECURITIES

         Equity Funds. The Equity Funds may invest in mortgage-backed securities
         issued by private issuers including Guaranteed CMOs and REMIC
         pass-through Securities that are rated in one of the four highest
         rating categories by at least one NRSRO at the time of investment or,
         if unrated, determined by Banc One Investment Advisors to be of
         comparable quality.

         Money Market Funds. The Money Market Funds may only invest in
         mortgage-backed securities issued or guaranteed by the U.S. government,
         or its agencies or instrumentalities. With respect to the Money Market
         Funds, mortgage-backed securities must be rated in one of the three
         highest rating categories by at least one NRSRO at the time of
         investment or, if unrated, determined by Banc One Investment Advisors
         to be of comparable quality.


         MORTGAGE DOLLAR ROLLS. Some of the Funds may enter into Mortgage Dollar
Rolls in which the Funds sell securities for delivery in the current month and
simultaneously contract with the same counterparty to repurchase



                                       14
<PAGE>   126


similar (same type, coupon and maturity) but not identical securities on a
specified future date. When a Fund enters into mortgage dollar rolls, the Fund
will hold and maintain a segregated account until the settlement date, cash or
liquid, high grade debt securities in an amount equal to the forward purchase
price. The Funds benefit to the extent of any difference between the price
received for the securities sold and the lower forward price for the future
purchase (often referred to as the "drop") or fee income plus the interest
earned on the cash proceeds of the securities sold until the settlement date of
the forward purchase. Unless such benefits exceed the income, capital
appreciation and gain or loss due to mortgage prepayments that would have been
realized on the securities sold as part of the mortgage dollar roll, the use of
this technique will diminish the investment performance of the Funds compared
with what such performance would have been without the use of mortgage dollar
rolls. The benefits derived from the use of mortgage dollar rolls may depend
upon Banc One Investment Advisors' ability to predict correctly mortgage
prepayments and interest rates. There is no assurance that mortgage dollar rolls
can be successfully employed. The Funds currently intend to enter into mortgage
dollar rolls that are accounted for as a financing transaction. For purposes of
diversification and investment limitations, mortgage dollar rolls are considered
to be mortgage-backed securities.

         STRIPPED MORTGAGE BACKED SECURITIES. Stripped Mortgage Backed
Securities ("SMBS") are derivative multi-class mortgage securities. SMBS are
usually structured with two classes that receive different proportions of the
interest and principal distributions from a pool of mortgage assets. A common
type of SMBS will have one class receiving all of the interest from the mortgage
assets ("IOS"), while the other class will receive all of the principal ("POS").
Mortgage IOs receive monthly interest payments based upon a notional amount that
declines over time as a result of the normal monthly amortization and
unscheduled prepayments of principal on the associated mortgage POs.

         In addition to the risks applicable to Mortgage-Related Securities in
general, SMBS are extremely sensitive to changes in prepayments and interest
rates. Even though such securities have been guaranteed by an agency or
instrumentality of the U.S. government, under certain interest rate or
prepayment rate scenarios, the Funds may fail to fully recover their investment
in such securities. Changes in prepayment rates can cause the return on
investment in IOs to be highly volatile, and under extremely high prepayment
conditions IOs can incur significant losses. POs are bought at a discount to the
ultimate principal repayment value. The rate of return on a PO will vary with
prepayments, rising as prepayment increase and falling as prepayments decrease.
The market value of the class consisting entirely of principal payments
generally is unusually volatile in response to changes in interest rates. The
yields on a class of SMBS that receives all or most of the interest from
mortgage assets are generally higher than prevailing market yields on other
mortgage-backed securities because their cash flow patterns are more volatile
and there is a greater risk that any premium paid will not be fully recouped.
Banc One Investment Advisors will seek to manage these risks (and potential
benefits) by investing in a variety of such securities and by using certain
analytical and hedging.

         The Equity Funds may invest in SMBS to enhance revenues or hedge
against interest rate risk. The Funds may only invest in SMBS issued or
guaranteed by the U.S. government, its agencies or instrumentalities. Although
the market for SMBS is increasingly liquid, certain SMBS may not be readily
marketable and will be considered illiquid for purposes of the Funds'
limitations on investments in illiquid securities.

         ADJUSTABLE RATE MORTGAGE LOANS. The Real Estate Fund may invest in
adjustable rate mortgage loans ("ARMS"). ARMs eligible for inclusion in a
mortgage pool will generally provide for a fixed initial mortgage interest rate
for a specified period of time. Thereafter, the interest rates (the "MORTGAGE
INTEREST RATES") may be subject to periodic adjustment based on changes in the
applicable index rate (the "INDEX RATE"). The adjusted rate would be equal to
the Index Rate plus a gross margin, which is a fixed percentage spread over the
Index Rate established for each ARM at the time of its origination.

         Adjustable interest rates can cause payment increases that some
borrowers may find difficult to make. However, certain ARMs may provide that the
Mortgage Interest Rate may not be adjusted to a rate above an applicable
lifetime maximum rate or below an applicable lifetime minimum rate for such ARM.
Certain ARMs may also be subject to limitations on the maximum amount by which
the Mortgage Interest Rate may adjust for any single adjustment period (the
"MAXIMUM ADJUSTMENT"). Other ARMs ("NEGATIVELY AMORTIZING



                                       15
<PAGE>   127


ARMS") may provide instead or as well for limitations on changes in the monthly
payment on such ARMs. Limitations on monthly payments can result in monthly
payments which are greater or less than the amount necessary to amortize a
Negatively Amortizing ARM by its maturity at the Mortgage Interest Rate in
effect in any particular month. In the event that a monthly payment is not
sufficient to pay the interest accruing on a Negatively Amortizing ARM, any such
excess interest is added to the principal balance of the loan, causing negative
amortization and will be repaid through future monthly payments. It may take
borrowers under Negatively Amortizing ARMs longer periods of time to achieve
equity and may increase the likelihood of default by such borrowers. In the
event that a monthly payment exceeds the sum of the interest accrued at the
applicable Mortgage Interest Rate and the principal payment which would have
been necessary to amortize the outstanding principal balance over the remaining
term of the loan, the excess (or "accelerated amortization") further reduces the
principal balance of the ARM. Negatively Amortizing ARMs do not provide for the
extension of their original maturity to accommodate changes in their Mortgage
Interest Rate. As a result, unless there is a periodic recalculation of the
payment amount (which there generally is), the final payment may be
substantially larger than the other payments. These limitations on periodic
increases in interest rates and on changes in monthly payment protect borrowers
from unlimited interest rate and payment increases.

         Certain adjustable rate mortgage loans may provide for periodic
adjustments of scheduled payments in order to amortize fully the mortgage loan
by its stated maturity. Other adjustable rate mortgage loans may permit their
stated maturity to be extended or shortened in accordance with the portion of
each payment that is applied to interest as affected by the periodic interest
rate adjustments.

         There are two main categories of indices which provide the basis for
rate adjustments on ARMs: those based on U.S. Treasury securities and those
derived from a calculated measure such as a cost of funds index or a moving
average of mortgage rates. Commonly utilized indices include the one-year,
three-year and five-year constant maturity Treasury bill rates, the three-month
Treasury bill rate, the 180-day Treasury bill rate, rates on longer-term
Treasury securities, the 11th District Federal Home Loan Bank Cost of Funds, the
National Median Cost of Funds, the one-month, three-month, six-month or one-year
London Interbank Offered Rate ("LIBOR"), the prime rate of a specific bank, or
commercial paper rates. Some indices, such as the one-year constant maturity
Treasury rate, closely mirror changes in market interest rate levels. Others,
such as the 11th District Federal Home Loan Bank Cost of Funds index, tend to
lag behind changes in market rate levels and tend to be somewhat less volatile.
The degree of volatility in the market value of the Fund's portfolio and
therefore in the net asset value of the Fund's shares will be a function of the
length of the interest rate reset periods and the degree of volatility in the
applicable indices.




                                       16
<PAGE>   128


         In general, changes in both prepayment rates and interest rates will
change the yield on Mortgage-Backed Securities. The rate of principal
prepayments with respect to ARMs has fluctuated in recent years. As is the case
with fixed mortgage loans, ARMs may be subject to a greater rate of principal
prepayments in a declining interest rate environment. For example, if prevailing
interest rates fall significantly, ARMs could be subject to higher prepayment
rates than if prevailing interest rates remain constant because the availability
of fixed rate mortgage loans at competitive interest rates may encourage
mortgagors to refinance their ARMs to "lock-in" a lower fixed interest rate.
Conversely, if prevailing interest rates rise significantly, ARMs may prepay at
lower rates than if prevailing rates remain at or below those in effect at the
time such ARMs were originated. As with fixed rate mortgages, there can be no
certainty as to the rate of prepayments on the ARMs in either stable or changing
interest rate environments. In addition, there can be no certainty as to whether
increases in the principal balances of the ARMs due to the addition of deferred
interest may result in a default rate higher than that on ARMs that do not
provide for negative amortization. Other factors affecting prepayment of ARMs
include changes in mortgagors' housing needs, job transfers, unemployment,
mortgagors' net equity in the mortgage properties and servicing decisions.

         RISKS FACTORS OF MORTGAGE-RELATED SECURITIES

         Guarantor Risk. There can be no assurance that the U.S. government
would provide financial support to Fannie Mae, Freddie Mac or Ginnie Mae if
necessary in the future. Although certain mortgage-related securities are
guaranteed by a third party or otherwise similarly secured, the market value of
the security, which may fluctuate, is not so secured.

         Interest Rate Sensitivity. If a Fund purchases a mortgage- related
security at a premium, that portion may be lost if there is a decline in the
market value of the security whether resulting from changes in interest rates or
prepayments in the underlying mortgage collateral. As with other
interest-bearing securities, the prices of such securities are inversely
affected by changes in interest rates. However, though the value of a
mortgage-related security may decline when interest rates rise, the converse is
not necessarily true since in periods of declining interest rates the mortgages
underlying the securities are prone to prepayment. For this and other reasons, a
mortgage-related security's stated maturity may be shortened by unscheduled
prepayments on the underlying mortgages and, therefore, it is not possible to
predict accurately the security's return to the Funds. In addition, regular
payments received in respect of mortgage-related securities include both
interest and principal. No assurance can be given as to the return the Funds
will receive when these amounts are reinvested.

         Market Value. The market value of the Fund's adjustable rate
Mortgage-Backed Securities may be adversely affected if interest rates increase
faster than the rates of interest payable on such securities or by the
adjustable rate mortgage loans underlying such securities. Furthermore,
adjustable rate Mortgage-Backed Securities or the mortgage loans underlying such
securities may contain provisions limiting the amount by which rates may be
adjusted upward and downward and may limit the amount by which monthly payments
may be increased or decreased to accommodate upward and downward adjustments in
interest rates.

         Prepayments. Although having less risk of decline during periods of
rising interest rates, adjustable rate Mortgage-Backed Securities have less
potential for capital appreciation than fixed rate Mortgage-Backed Securities
because their coupon rates will decline in response to market interest rate
declines. The market value of fixed rate Mortgage-Backed Securities may be
adversely affected as a result of increases in interest rates and, because of
the risk of unscheduled principal prepayments, may benefit less than other fixed
rate securities of similar maturity from declining interest rates. Finally, to
the extent Mortgage-Backed Securities are purchased at a premium, mortgage
foreclosures and unscheduled principal prepayments may result in some loss of
the Fund's principal investment to the extent of the premium paid. On the other
hand, if such securities are purchased at a discount, both a scheduled payment
of principal and an unscheduled prepayment of principal will increase current
and total returns and will accelerate the recognition of income.

         Yield Characteristics. The yield characteristics of Mortgage-Backed
Securities differ from those of traditional fixed income securities. The major
differences typically include more frequent interest and principal payments,
usually monthly, and the possibility that prepayments of principal may be made
at any time. Prepayment 



                                       17
<PAGE>   129


rates are influenced by changes in current interest rates and a variety of
economic, geographic, social and other factors and cannot be predicted with
certainty. As with fixed rate mortgage loans, adjustable rate mortgage loans may
be subject to a greater prepayment rate in a declining interest rate
environment. The yields to maturity of the Mortgage-Backed Securities in which
the Funds invest will be affected by the actual rate of payment (including
prepayments) of principal of the underlying mortgage loans. The mortgage loans
underlying such securities generally may be prepaid at any time without penalty.
In a fluctuating interest rate environment, a predominant factor affecting the
prepayment rate on a pool of mortgage loans is the difference between the
interest rates on the mortgage loans and prevailing mortgage loan interest rates
(giving consideration to the cost of any refinancing). In general, if mortgage
loan interest rates fall sufficiently below the interest rates on fixed rate
mortgage loans underlying mortgage pass-through securities, the rate of
prepayment would be expected to increase. Conversely, if mortgage loan interest
rates rise above the interest rates on the fixed rate mortgage loans underlying
the mortgage pass-through securities, the rate of prepayment may be expected to
decrease.

NEW FINANCIAL PRODUCTS

         New options and futures contracts and other financial products, and
various combinations thereof, continue to be developed and certain of the Funds
may invest in any such options, contracts and products as may be developed to
the extent consistent with each Fund's investment objective, policies and
restrictions and the regulatory requirements applicable to investment companies.

         These various products may be used to adjust the risk and return
characteristics of each Fund's investments. These various products may increase
or decrease exposure to security prices, interest rates, commodity prices, or
other factors that affect security values, regardless of the issuer's credit
risk. If market conditions do not perform consistent with expectations, the
performance of each Fund would be less favorable than it would have been if
these products were not used. In addition, losses may occur if counterparties
involved in transactions do not perform as promised. These products may expose
the Fund to potentially greater return as well as potentially greater risk of
loss than more traditional fixed income investments.

PERCS*

         The Equity Funds may invest in Preferred Equity Redemption Cumulative
Stock ("PERCS") which is a form of convertible preferred stock that actually has
more of an equity component than it does fixed income characteristics. These
instruments permit companies to raise capital via a surrogate for common equity.
PERCS are preferred stock which convert to common stock after a specified period
of time, usually three years, and are considered the equivalent of equity by the
ratings agencies. Issuers pay holders a substantially higher dividend yield than
that on the underlying common stock, and in exchange, the holder's appreciation
is capped, usually at about 30 percent. The PERC is mandatorily convertible into
common stock, but is callable at any time at an initial call price that reflects
a substantial premium to the stock's issue price. The call price declines daily
in an amount that reflects the incremental dividend that holders enjoy. PERCS
are listed on an exchange where the common stock is listed.

         *PERCS is a registered trademark of Morgan Stanley, which does not
sponsor and is in no way affiliated with One Group.

PREFERRED STOCK

         Preferred stock is a class of stock that generally pays dividends at a
specified rate and has preference over common stock in the payment of dividends
and liquidation. Preferred stock generally does not carry voting rights. As with
all equity securities, the price of preferred stock fluctuates based on changes
in a company's financial condition and on overall market and economic
conditions.

REAL ESTATE INVESTMENT TRUSTS ("REITS")

         Certain of the Funds may invest in equity interests or debt obligations
issued by REITs. REITs are pooled investment vehicles which invest primarily in
income producing real estate or real estate related loans or interest. REITs are
generally classified as equity REITs, mortgage REITs or a combination of equity
and mortgage REITs. Equity REITs invest the majority of their assets directly in
real property and derive income primarily from the collection of rents. Equity
REITs can also realize capital gains by selling property that has appreciated in
value. Mortgage REITs invest the majority of their assets in real estate
mortgages and derive income from the collection of interest payments. Similar to
investment companies, REITs are not taxed on income distributed to shareholders
provided they comply with several requirements of the Code. A Fund will
indirectly bear its proportionate share of expenses incurred by REITs in which a
Fund invests in addition to the expenses incurred directly by a Fund.

         Investing in REITs involves certain unique risks in addition to those
risks associated with investing in the real estate industry in general. Equity
REITs may be affected by changes in the value of the underlying property owned
by the REITs, while mortgage REITs may be affected by the quality of any credit
extended. REITs are dependent upon management skills, are not diversified, are
subject to heavy cash flow dependency, default by borrowers and
self-liquidation. REITs are also subject to the possibilities of failing to
qualify for tax free pass-through of income under the Code and failing to
maintain their exemption from registration under the Act.

         REITs (especially mortgage REITs) are also subject to interest rate
risks. When interest rates decline, the value of a REIT's investment in fixed
rate obligations can be expected to rise. Conversely, when interest rates rise,
the value of a REIT's investment in fixed rate obligations can be expected to
decline. In contrast, as interest rates on adjustable rate mortgage loans are
reset periodically, yields on a REIT's investment in such loans will gradually
align themselves to fluctuate less dramatically in response to interest rate
fluctuations than would investments in fixed rate obligations.

         Investment in REITs involves risks similar to those associated with
investing in small capitalization companies. REITs may have limited financial
resources, may trade less frequently and in a limited volume and may be subject
to more abrupt or erratic price movements than larger company securities.
Historically, small capitalization stocks, such as REITs, have been more
volatile in price than the larger capitalization stocks included in the S&P
Index of 500 Common Stocks.

REPURCHASE AGREEMENTS

         Under the terms of a repurchase agreement, a Fund would acquire
securities from a seller, 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 the value of collateral held pursuant to the agreement at
not less than the repurchase price (including accrued interest).

         If the seller were to default on its repurchase obligation or become
insolvent, the Fund holding such obligation would suffer a loss to the extent
that the proceeds from a sale of the underlying portfolio securities were less
than the repurchase price under the agreement, or to the extent that the
disposition of such securities by the Fund were delayed pending court action.
Additionally, there is no controlling legal precedent under U.S. law and there
may be no controlling legal precedents under the laws of certain foreign
jurisdictions confirming that a Fund would be entitled, as against a claim by
such seller or its receiver or trustee in bankruptcy, to retain the underlying
securities, although (with respect to repurchase agreements subject to U.S. law)
the Board of Trustees of the Trust believes that, under the regular procedures
normally in effect for custody of a Fund's securities subject to repurchase
agreements and under federal laws, a court of competent jurisdiction would rule
in favor of the Trust if presented with the question. Securities subject to
repurchase agreements will be held by the Trust's custodian or another qualified
custodian or in the Federal Reserve/Treasury book-entry system. Repurchase
agreements are considered by the SEC to be loans by a Fund under the 1940 Act.

Federal Reserve member banks with assets in excess of $1 billion and registered
broker dealers which Banc One Investment Advisors.

REVERSE REPURCHASE AGREEMENTS

         Funds may borrow money for temporary purposes by entering into reverse
repurchase agreements. Pursuant to such agreements, a Fund would sell portfolio
securities to financial institutions such as banks and broker-dealers, and agree
to repurchase them at a mutually agreed-upon date and price. A Fund would enter
into reverse repurchase agreements only to avoid otherwise selling securities
during unfavorable market conditions to meet redemptions. At the time a Fund
entered into a reverse repurchase agreement, it would place in a segregated
custodial account assets, such as cash or liquid securities consistent with the
Fund's investment restrictions and having a value equal to the repurchase price
(including accrued interest), and would subsequently monitor the account to
ensure that such equivalent value was maintained. Reverse repurchase agreements
involve the risk that the market value of the securities sold by a Fund may
decline below the price at which the Fund is obligated to repurchase the
securities. Reverse repurchase agreements are considered by the SEC to be
borrowings by a Fund under the 1940 Act.

RESTRICTED SECURITIES

         Some of the Funds may invest in commercial paper issued in reliance on
the exemption from registration afforded by Section 4(2) of the Securities Act
of 1933 and other restricted securities. Section 4(2) commercial paper is
restricted as to disposition under federal securities law and is generally sold
to institutional investors, such as the Funds, who agree that they are
purchasing the paper for investment purposes and not with a view to public
distribution. Any resale by the purchaser must be in an exempt transaction.
Section 4(2) commercial paper is normally resold to other institutional
investors like the Funds through or with the assistance of the issuer or
investment dealers who make a market in Section 4(2) commercial paper, thus
providing liquidity. The Funds believe that Section 4(2) commercial paper and
possibly certain other restricted securities which meet the criteria for
liquidity established by the Trustees are quite liquid. The Funds intend,
therefore, to treat restricted securities that meet the liquidity criteria
established by the Board of Trustees, including Section 4(2) commercial paper
and Rule 144A Securities, as determined by Banc One Investment Advisors, as
liquid and not subject to the investment limitation applicable to illiquid
securities.

         The ability of the Trustees to determine the liquidity of certain
restricted securities is permitted under a SEC Staff position set forth in the
adopting release for Rule 144A under the Securities Act of 1933 ("RULE 144A").
Rule 144A is a nonexclusive safe-harbor for certain secondary market
transactions involving securities subject to restrictions on resale under
federal securities laws. Rule 144A provides an exemption from registration for
resales of otherwise restricted securities to qualified institutional buyers.
Rule 144A was expected to further enhance the liquidity of the secondary market
for securities eligible for resale. The Funds believe that the Staff of the SEC
has left the question of determining the liquidity of all restricted securities
to the Trustees. The Trustees have directed Banc One Investment Advisors to
consider the following criteria in determining the liquidity of certain
restricted securities:

         o        the frequency of trades and quotes for the security;

         o        the number of dealers willing to purchase or sell the security
                  and the number of other potential buyers;

         o        dealer undertakings to make a market in the security; and

         o        the nature of the security and the nature of the marketplace
                  trades.

         Certain Section 4(2) commercial paper programs cannot rely on Rule 144A
because, among other things, they were established before the adoption of the
rule. However, the Trustees may determine for purposes of the




                                       20
<PAGE>   132


Trust's liquidity requirements that an issue of 4(2) commercial paper is liquid
if the following conditions, which are set forth in a 1994 SEC no-action letter,
are met:

         o        The 4(2) paper must not be traded flat or in default as to
                  principal or interest;

         o        The 4(2) paper must be rated in one of the two highest rating
                  categories by a least two NRSROS, or if only one NRSRO rates
                  the security, by that NRSRO, or if unrated, is determined by
                  Banc One Investment Advisors to be of equivalent quality; and

         o        Banc One Investment Advisors must consider the trading market
                  for the specific security, taking into account all relevant
                  factors, including but not limited, to whether the paper is
                  the subject of a commercial paper program that is administered
                  by an issuing and paying agent bank and for which there exists
                  a dealer willing to make a market in that paper, or is
                  administered by a direct issuer pursuant to a direct placement
                  program; and

         o        Banc One Investment Advisors shall monitor the liquidity of
                  the 4(2) commercial paper purchased and shall report to the
                  Board of Trustees promptly if any such securities are no
                  longer determined to be liquid if such determination causes a
                  Fund to hold more than 15% (10% for Money Market Funds) of its
                  net assets in illiquid securities in order for the Board of
                  Trustees to consider what action, if any, should be taken on
                  behalf of The One Group, unless Banc One Investment Advisors
                  is able to dispose of illiquid assets in an orderly manner in
                  an amount that reduces the Fund's holdings of illiquid assets
                  to less than 15% (10% for Money Market Funds) of its net
                  assets; and

         o        Banc One Investment Advisors shall report to the Board of
                  Trustees on the appropriateness of the purchase and retention
                  of liquid restricted securities under these Guidelines no less
                  frequently that quarterly.

SECURITIES LENDING

         In order to generate additional income, each of the Funds, except the
Treasury Prime Money Market Fund may lend up to 33 1/3% of the securities in
which they are invested pursuant to agreements requiring that the loan be
continuously secured by cash, securities of the U.S. government or its agencies,
shares of an investment trust or mutual fund, letters of credit or any
combination of cash, such securities, shares, or letters of credit as collateral
equal at all times to at least 100% of the market value plus accrued interest on
the securities lent. The Funds will continue to receive interest on the
securities lent while simultaneously seeking to earn interest on the investment
of cash collateral in U.S. government securities, shares of an investment trust
or mutual fund, or commercial paper, repurchase agreements, variable and
floating rate instruments, restricted securities, asset-backed securities, and
the other types of investments permitted by the applicable Fund's prospectus.
Collateral is marked to market daily to provide a level of collateral at least
equal to the market value of the securities lent. There may be risks of delay in
recovery of the securities or even loss of rights in the collateral should the
borrower of the securities fail financially. However, loans will only be made to
borrowers deemed by Banc One Investment Advisors to be of good standing under
guidelines established by the Trust's Board of Trustees and when, in the
judgment of Banc One Investment Advisors, the consideration which can be earned
currently from such securities loans justifies the attendant risk. Loans are
subject to termination by the Funds or the borrower at any time, and are
therefore, not considered to be illiquid investments.

SWAPS, CAPS AND FLOORS

         Certain of the Funds may enter into swaps, caps, and floors on various
securities (such as U.S. government securities), securities indexes, interest
rates, prepayment rates, foreign currencies or other financial instruments or
indexes, in order to protect the value of the Fund from interest rate
fluctuations and to hedge against fluctuations in the floating rate market in
which the Fund's investments are traded, for both hedging and non-hedging
purposes. While swaps, caps, and floors (sometimes hereinafter collectively
referred to as "SWAP CONTRACTS") are different from futures contracts (and
options on futures contracts) in that swap contracts are individually negotiated




                                       21
<PAGE>   133


with specific counterparties, the Funds will use swap contracts for purposes
similar to the purposes for which they use options, futures, and options on
futures. Those uses of swap contracts (i.e. , risk management and hedging)
present the Funds with risks and opportunities similar to those associated with
options contracts, futures contracts, and options on futures. See "Futures
Contracts" and "Risk Factors in Futures Contracts."

         The Funds may enter into these transactions to manage their exposure to
changing interest rates and other market factors. Some transactions may reduce
each Fund's exposure to market fluctuations while others may tend to increase
market exposure.

         Swap contracts typically involve an exchange of obligations by two
sophisticated parties. For example, in an interest rate swap, the Fund may
exchange with another party their respective rights to receive interest, such as
an exchange of fixed rate payments for floating rate payments. Currency swaps
involve the exchange of respective rights to make or receive payments in
specified currencies. Mortgage swaps are similar to interest rate swaps in that
they represent commitments to pay and receive interest. The notional principal
amount, however, is tied to a reference pool or pools of mortgages.

         Caps and floors are variations on swaps. The purchase of a cap entitles
the purchaser to receive a principal amount from the party selling the cap to
the extent that a specified index exceeds a predetermined interest rate or
amount. The purchase of an interest rate floor entitles the purchaser to receive
payments on a notional principal amount from the party selling the floor to the
extent that a specified index falls below a predetermined interest rate or
amount. Caps and floors are similar in many respects to over-the-counter options
transactions, and may involve investment risks that are similar to those
associated with options transactions and options on futures contracts.

         Because swap contracts are individually negotiated, they remain the
obligation of the respective counterparties, and there is a risk that a
counterparty will be unable to meet its obligations under a particular swap
contract. If a counterparty defaults on a swap contract with a Fund, the Fund
may suffer a loss. To address this risk, each Fund will usually enter into
interest rate swaps on a net basis, which means that the two payment streams
(one from the Fund to the counterparty, one to the Fund from the counterparty)
are netted out, with the Fund receiving or paying, as the case may be, only the
net amount of the two payments. Interest rate swaps do not involve the delivery
of securities, other underlying assets, or principal, except for the purposes of
collateralization as discussed below. Accordingly, the risk of loss with respect
to interest rate swaps entered into on a net basis would be limited to the net
amount of the interest payments that the Fund is contractually obligated to
make. If the other party to an interest rate swap defaults, the Fund's risk of
loss consists of the net amount of interest payments that a Fund is
contractually entitled to receive. In addition, the Fund may incur a market
value adjustment on securities held upon the early termination of the swap. To
protect against losses related to counterparty default, the Funds may enter into
swaps that require transfers of collateral for changes in market value. In
contrast, currency swaps and other types of swaps may involve the delivery of
the entire principal value of one designated currency or financial instrument in
exchange for the other designated currency or financial instrument. Therefore,
the entire principal value of such swaps may be subject to the risk that the
other party will default on its contractual delivery obligations.

         In addition, because swap contracts are individually negotiated and
ordinarily non-transferable, there also may be circumstances in which it would
be impossible for a Fund to close out its obligations under the swap contract
prior to its maturity. Under such circumstances, the Fund might be able to
negotiate another swap contract with a different counterparty to offset the risk
associated with the first swap contract. Unless the Fund is able to negotiate
such an offsetting swap contract, however, the Fund could be subject to
continued adverse developments, even after Banc One Investment Advisors has
determined that it would be prudent to close out or offset the first swap
contract.

         The Funds will not enter into any mortgage swap, interest rate swap,
cap or floor transaction unless the unsecured commercial paper, senior debt, or
the claims paying ability of the other party thereto is rated in one of the top
two rating categories by at least one NRSRO, or if unrated, determined by Banc
One Investment Advisors to be of comparable quality.


                                       22
<PAGE>   134


         The use of swaps involves investment techniques and risks different
from and potentially greater than those associated with ordinary Fund securities
transactions. If Banc One Investment Advisors is incorrect in its expectations
of market values, interest rates, or currency exchange rates, the investment
performance of the Funds would be less favorable than it would have been if this
investment technique were not used. In addition, in certain circumstances entry
into a swap contract that substantially eliminates risk of loss and the
opportunity for gain in an "appreciated financial position" will accelerate gain
to the Funds.

         The Staff of the SEC is presently considering its position with respect
to swaps, caps and floors as senior securities. Pending a determination by the
Staff, the Funds will either treat swaps, caps and floors as being subject to
their senior securities restrictions or will refrain from engaging in swaps,
caps and floors. Once the Staff has expressed a position with respect to swaps,
caps and floors, the Funds intend to engage in swaps, caps and floors, if at
all, in a manner consistent with such position. To the extent the net amount of
an interest rate or mortgage swap is held in a segregated account, consisting of
cash or liquid, high grade debt securities, the Funds and Banc One Investment
Advisors believe that swaps do not constitute senior securities under the
Investment Company Act of 1940 and, accordingly, will not treat them as being
subject to each Fund's borrowing restrictions. The net amount of the excess, if
any, of each Fund's obligations over its entitlements with respect to each
interest rate swap will be accrued on a daily basis and an amount of cash or
liquid securities having an aggregate net asset value at least equal to the
accrued excess will be maintained in a segregated account by the Funds'
Custodian.

TREASURY RECEIPTS

         Certain of the Funds may purchase interests in separately traded
interest and principal component parts of U.S. Treasury obligations that are
issued by banks or brokerage firms and are created by depositing U.S. Treasury
notes and U.S. Treasury bonds into a special account at a custodian bank.
Receipts include Treasury Receipts ("TRS"), Treasury Investment Growth Receipts
("TIGRS"), and Certificates of Accrual on Treasury Securities ("CATS").

U.S. TREASURY OBLIGATIONS

         The Funds may invest in bills, notes and bonds issued by the U.S.
Treasury and separately traded interest and principal component parts of such
obligations that are transferable through the Federal book-entry system known as
Separately Traded Registered Interest and Principal Securities ("STRIPS") and
Coupon Under Book Entry Safekeeping ("CUBES"). The Funds may also invest in
Inflation Indexed Treasury Obligations.

VARIABLE AND FLOATING RATE INSTRUMENTS

         Certain obligations purchased by some of the Funds may carry variable
or floating rates of interest, may involve a conditional or unconditional demand
feature and may include variable amount master demand notes.

         VARIABLE AMOUNT MASTER DEMAND NOTES are demand notes that permit the
indebtedness thereunder to vary and provide for periodic adjustments in the
interest rate according to the terms of the instrument. Because master demand
notes are direct lending arrangements between a Fund and the issuer, they are
not normally traded. Although there is no secondary market in the notes, a Fund
may demand payment of principal and accrued interest. While the notes are not
typically rated by credit rating agencies, issuers of variable amount master
demand notes (which are normally manufacturing, retail, financial, brokerage,
investment banking and other business concerns) must satisfy the same criteria
as set forth above for commercial paper. Banc One Advisers will consider the
earning power, cash flow, and other liquidity ratios of the issuers of such
notes and will continuously monitor their financial status and ability to meet
payment on demand. In determining average weighted portfolio maturity, a
variable amount master demand note will be deemed to have a maturity equal to
the period of time remaining until the principal amount can be recovered from
the issuer through demand.

         Some of the Funds subject to their investment objective policies and
restrictions, may acquire VARIABLE AND FLOATING RATE INSTRUMENTS. A variable
rate instrument is one whose terms provide for the adjustment of its interest
rate on set dates and which, upon such adjustment, can reasonably be expected to
have a 



                                       23
<PAGE>   135


market value that approximates its par value. Some of the Funds may purchase
EXTENDABLE COMMERCIAL NOTES. Extendable commercial notes are variable rate notes
which normally mature within a short period of time (e.g., 1 month) but which
may be extended by the issuer for a maximum maturity of thirteen months.

         A floating rate instrument is one whose terms provide for the
adjustment of its interest rate whenever a specified interest rate changes and
which, at any time, can reasonably be expected to have a market value that
approximates its par value. Floating rate instruments are frequently not rated
by credit rating agencies; however, unrated variable and floating rate
instruments purchased by a Fund will be determined by Banc One Investment
Advisors under guidelines established by the Trust's Board of Trustees to be of
comparable quality at the time of purchase to rated instruments eligible for
purchase under the Fund's investment policies. In making such determinations,
Banc One Investment Advisors will consider the earning power, cash flow and
other liquidity ratios of the issuers of such instruments (such issuers include
financial, merchandising, bank holding and other companies) and will
continuously monitor their financial condition. There may be no active secondary
market with respect to a particular variable or floating rate instrument
purchased by a Fund. The absence of such an active secondary market, could make
it difficult for the Fund to dispose of the variable or floating rate instrument
involved in the event the issuer of the instrument defaulted on its payment
obligations, and the Fund could, for this or other reasons, suffer a loss to the
extent of the default. Variable or floating rate instruments may be secured by
bank letters of credit or other assets. A Fund will purchase a variable or
floating rate instrument to facilitate portfolio liquidity or to permit
investment of the Fund's assets at a favorable rate of return.

         With respect to the Money Market Funds, variable or floating rate
instruments with stated maturities of more than 397 days may, under the
Securities and Exchange Commission's amortized cost rule, Rule 2a-7 under the
1940 Act, be deemed to have shorter maturities as follows:

         (1) Adjustable Rate Government Securities. A Government Security which
is a Variable Rate Security where the variable rate of interest is readjusted no
less frequently than every 762 days shall be deemed to have a maturity equal to
the period remaining until the next readjustment of the interest rate. A
Government Security which is a Floating Rate Security shall be deemed to have a
remaining maturity of one day.

         (2) Short-Term Variable Rate Securities. A Variable Rate Security, the
principal amount of which, in accordance with the terms of the security, must
unconditionally be paid in 397 calendar days or less shall be deemed to have
maturity equal to the earlier of the period remaining until the next
readjustment of the interest rate or the period remaining until the principal
amount can be recovered through demand.

         (3) Long-Term Variable Rate Securities. A Variable Rate Security, the
principal amount of which is scheduled to be paid in more than 397 days, that is
subject to a Demand Feature shall be deemed to have a maturity equal to the
longer of the period remaining until the next readjustment of the interest rate
or the period remaining until the principal amount can be recovered through
demand.

         (4) Short-Term Floating Rate Securities. A Floating Rate Security, the
principal amount of which, in accordance with the terms of the security, must
unconditionally be paid in 397 calendar days or less shall be deemed to have a
maturity of one day.

         (5) Long-Term Floating Rate Securities. A Floating Rate Security, the
principal amount of which is scheduled to be paid in more than 397 days, that is
subject to a demand feature, shall be deemed to have a maturity equal to the
period remaining until the principal amount can be recovered through demand.

         As used above, a note is "subject to a demand feature" where the Fund
is entitled to receive the principal amount of the note either at any time on no
more than thirty days' notice or at specified intervals not exceeding 397
calendar days and upon no more than 30 days notice.

         LIMITATIONS ON THE USE OF VARIABLE AND FLOATING RATE NOTES. Variable
and floating rate instruments for which no readily available market exists will
be purchased in an amount which, together with securities with legal or
contractual restrictions on resale or for which no readily available market
exists (including repurchase agreements 



                                       24
<PAGE>   136


providing for settlement more than seven days after notice), exceeds 10% (with
respect to the Money Market Funds) or 15% (with respect to all Funds, other than
the Money Market Funds, which can purchase such notes) of the Fund's net assets
only if such instruments are subject to a demand feature that will permit the
Fund to demand payment of the principal within seven days after demand by the
Fund. There is no limit on the extent to which a Fund may purchase demand
instruments that are not illiquid. If not rated, such instruments must be found
by Banc One Investment Advisors, under guidelines established by the Trust's
Board of Trustees, to be of comparable quality to instruments that are rated
high quality. A rating may be relied upon only if it is provided by a nationally
recognized statistical rating organization that is not affiliated with the
issuer or guarantor of the instruments. For a description of the rating symbols
of S&P, Moody's, and Fitch used in this paragraph, see the Appendix. The above
Funds may also invest in Canadian Commercial Paper which is commercial paper
issued by a Canadian corporation or a Canadian counterpart of a U.S. corporation
and in Europaper which is U.S. dollar denominated commercial paper of a foreign
issuer.

WARRANTS

         Warrants are securities, typically issued with preferred stock or
bonds, that give the holder the right to buy a proportionate amount of common
stock at a specified price, usually at a price that is higher than the market
price at the time of issuance of the warrant. The right may last for a period of
years or indefinitely.

WHEN-ISSUED SECURITIES AND FORWARD COMMITMENTS

         Some Funds may purchase securities on a "when-issued" and forward
commitment basis. When a Fund agrees to purchase securities, the Fund's
custodian will set aside cash or liquid portfolio securities equal to the amount
of the commitment in a separate account. The Funds may purchase securities on a
when-issued basis when deemed by Banc One Investment Advisors to present
attractive investment opportunities. When-issued securities are purchased for
delivery beyond the normal settlement date at a stated price and yield, thereby
involving the risk that the yield obtained will be less than that available in
the market at delivery. The Funds generally will not pay for such securities or
earn interest on them until received. Although the purchase of securities on a
when-issued basis is not considered to be leveraging, it has the effect of
leveraging. When Banc One Investment Advisors purchases a when-issued security,
the Custodian will set aside cash or liquid securities to satisfy the purchase
commitment. In such a case, a 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 the Fund's commitment. The Fund's net
assets may fluctuate to a greater degree when it sets aside portfolio securities
to cover such purchase commitments than when it sets aside cash. In addition,
when a Fund engages in "when-issued" transactions, it relies on the seller to
consummate the trade. Failure of the seller to do so may result in the Fund's
incurring a loss or missing the opportunity to obtain a price considered to be
advantageous.

         In a forward commitment transaction, the Funds contract to purchase
securities for a fixed price at a future date beyond customary settlement time.
The Funds are required to hold and maintain in a segregated account until the
settlement date, cash, U.S. government securities or liquid high-grade debt
obligations in an amount sufficient to meet the purchase price. Alternatively,
the Funds may enter into offsetting contracts for the forward sale of other
securities that they own. The purchase of securities on a when-issued or forward
commitment basis involves a risk of loss if the value of the security to be
purchased declines prior to the settlement date.

         Limitations on the Use of When Issued Securities and Forward
Commitments. No Fund intends to purchase "when-issued" securities for
speculative purposes but only for the purpose of acquiring portfolio securities.
Because a Fund will set aside cash or liquid portfolio securities to satisfy its
purchase commitments in the manner described, the Fund's liquidity and the
ability of Banc One Investment Advisors to manage the Fund might, as described
in the Prospectuses, be affected in the event its commitments to purchase
when-issued securities ever exceeded 40% of the value of its assets. Commitments
to purchase when-issued securities will not, under normal market conditions,
exceed 25% of a Fund's total assets, and a commitment will not exceed 90 days. A
Fund may dispose of a when-issued security or forward commitment prior to
settlement if Banc One Investment Advisors deems it appropriate to do so.

INVESTMENT RESTRICTIONS

         The following investment restrictions are FUNDAMENTAL and may be
changed with respect to a particular Fund only by a vote of a majority of the
outstanding Shares of that Fund. See "ADDITIONAL INFORMATION--Miscellaneous" in
this Statement of Additional Information.

         Each of the Equity Funds may not:

         1. Purchase securities of any issuer (except securities issued or
guaranteed by the United States, its agencies or instrumentalities, and, if
consistent with a Fund's investment objective and policies, repurchase
agreements involving such securities) if as a result more than 25% of the total
assets of a Fund would be invested in the securities of such issuer. This
restriction applies to 50% of a Fund's assets. With respect to the remaining 50%
of its total assets, a Fund may not purchase the securities of any issuer if as
a result more than 5% of the total assets of the Fund would be invested in the
securities of such issuer. For purposes of these limitations, a security is
considered to be issued by the government entity whose assets and revenues
guarantee or back the security. With respect to private activity bonds or
industrial development bonds backed only by the assets and revenues of a
non-governmental user, such user would be considered the issuer.

   
         2. Purchase any securities that would cause more than 25% of the total
assets of a Fund to be invested in the securities of one or more issuers
conducting their principal business activities in the same industry, provided
(i) that this limitation does not apply to investments in the obligations issued
or guaranteed by the U.S. government or its agencies and instrumentalities and
repurchase agreements involving such securities; (ii) with respect to the Real
Estate Fund, this limitation does not apply to investments in the real estate
industry; and (iii) with respect to investments in the Technology Fund, this
limitation does not apply to the technology sector. For purposes of this
limitation (i) utilities will be divided according to their services (for
example, gas, gas transmission, electric and telephone will each be considered a
separate industry); and (ii) 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.
    

         3. Make loans, except that a Fund may (i) purchase or hold debt
instruments in accordance with its investment objective and policies; (ii) enter
into repurchase agreements; and (iii) engage in securities lending as described
in the Prospectus and in this Statement of Additional Information.

         Each of the Money Market Funds may not:

         1. Purchase securities of any issuer (except securities issued or
guaranteed by the United States, its agencies or instrumentalities, and, if
consistent with the Fund's investment objective and policies, repurchase
agreements involving such securities) if as a result more than 5% of the total
assets of a Fund would be invested in the securities of such issuer or a Fund
would own more than 10% of the outstanding voting securities of such issuer,
provided, however, that a Fund may invest up to 25% of its total assets without
regard to this restriction as permitted by applicable law. For purposes of these
limitations, a security is considered to be issued by the government entity
whose assets and revenues guarantee or back the security. With respect to
private activity bonds or industrial development bonds backed only by the assets
and revenues of a nongovernmental user, such user would be considered the
issuer.

         2. Purchase any securities that would cause more than 25% of the total
assets of a Fund to be invested in the securities of one or more issuers
conducting their principal business activities in the same industry provided
that (i) this limitation does not apply to investments in the obligations issued
or guaranteed by the U.S. government or its agencies and instrumentalities,
domestic bank certificates of deposit or bankers' acceptance and repurchase
agreements involving such securities; (ii) 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 (iii)
utilities will be divided according to their services (for example, gas, gas
transmission, electric and telephone will each be considered a separate
industry.)

         3. Make loans, except that a Fund may (i) purchase or hold debt
instruments in accordance with its investment objective and policies; (ii) enter
into repurchase agreements; and (iii) engage in securities lending as described
in the Prospectus and in this Statement of Additional Information.

         None of the Funds may:

         1. Purchase securities on margin or sell securities short.

         2. Underwrite the securities of other issuers except to the extent that
a Fund may be deemed to be an underwriter under certain securities laws in the
disposition of "restricted securities."

         3. Purchase or sell commodities or commodity contracts (including
futures contracts), except that for bona fide hedging and other permissible
purposes: (i) the Equity Funds may purchase or sell financial futures contracts
and may purchase call or put options on financial futures contracts.

         4. Purchase participation or other direct interests in oil, gas or
mineral exploration or development programs (although investments by all Funds
in marketable securities of companies engaged in such activities are not hereby
precluded).

         5. Invest in any issuer for purposes of exercising control or
management.

         6. Purchase securities of other investment companies except as
permitted by the 1940 Act and rules, regulations and applicable exemptive relief
thereunder.

         7. Purchase or sell real estate unless acquired as a result of
ownership of securities or other instruments (however, each Fund except the
Money Market Funds may, to the extent appropriate to its investment objective,
purchase securities secured by real estate or interests therein or securities
issued by companies investing in real estate or interests therein).

         8. Borrow money or issue senior securities, except that each Fund may
borrow from banks or enter into reverse repurchase agreements for temporary
purposes in amounts up to 10% of the value of its total assets at the time of
such borrowing; or mortgage, pledge, or hypothecate any assets, except in
connection with any such borrowing and in amounts not in excess of the lesser of
the dollar amounts borrowed or 10% of the value of the Fund's total assets at
the time of its borrowing. A Fund will not purchase securities while its
borrowings (including reverse repurchase agreements) in excess of 5% of its
total assets are outstanding.

         The following investment restrictions are NON-FUNDAMENTAL except as
noted otherwise and therefore can be changed by the Board of Trustees without
prior shareholder approval.

         No Fund may:

         1. Invest in illiquid securities in an amount exceeding, in the
aggregate 15% of the Fund's net assets (10% of net assets for a Fund that is a
Money Market Fund). An illiquid security is a security which cannot be disposed
of promptly (within seven days) and in the usual course of business without a
loss, and includes repurchase agreements maturing in excess of seven days, time
deposits with a withdrawal penalty, non-negotiable instruments and instruments
for which no market exists.

         2. Acquire the securities of registered open-end investment companies
or registered unit investment trusts in reliance on Section 12(d)(1)(F) or
12(d)(1)(G) of the 1940 Act.

         The foregoing percentages apply at the time of purchase of a security.
Banc One Investment Advisors shall report to the Board of Trustees promptly if
any of a Fund's investments are no longer determined to be liquid or if the
market value of Fund assets has changed if such determination or change causes a
Fund to hold more than 15% (10% in the case of a Fund that is a Money Market
Fund) of its net assets in illiquid securities in order for the Board



                                       27
<PAGE>   139


of Trustees to consider what action, if any, should be taken on behalf of the
Trust, unless Banc One Investment Advisors is able to dispose of illiquid assets
in an orderly manner in an amount that reduces the Fund's holdings of illiquid
assets to less than 15% (or 10% in the case of a Fund that is a Money Market
Fund) of its net assets.

PORTFOLIO TURNOVER

         The portfolio turnover rate for each Fund is calculated by dividing the
lesser of purchases or sales of portfolio securities for the year by the monthly
average value of the portfolio securities. The calculation excludes all
securities whose maturities at the time of acquisition were one year or less.
Thus, for regulatory purposes, the portfolio turnover rates with respect to the
Money Market Funds are expected to be zero.

         The portfolio turnover rate for Real Estate Fund and Technology Fund is
not expected to exceed 50% and 100%, respectively, however, the rate may vary
from year to year. Higher portfolio turnover rates will likely result in higher
transaction costs to the Funds and may result in additional tax consequences to
Shareholders. To the extent portfolio turnover results in short-term capital
gains, such gains will generally be taxed at ordinary income tax rates.
Portfolio turnover may vary greatly from year to year as well as within a
particular year, and may also be affected by cash requirements for redemptions
of Shares. Portfolio turnover will not be a limiting factor in making portfolio
decisions.

ADDITIONAL TAX INFORMATION CONCERNING ALL FUNDS

         Each Fund is treated as a separate entity for federal income tax
purposes and is not combined with The One Group's other funds. It is the policy
of each Fund of the Trust to meet the requirements necessary to qualify as a
"regulated investment company" under Subchapter M of the Internal Revenue Code
of 1986, as amended (the "Code"). By following such policy, each Fund expects to
eliminate or reduce to a nominal amount the federal income taxes to which it may
be subject.

         In order to qualify as a regulated investment company, each Fund must,
among other things, (1) 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 stock or securities, foreign currencies or other income
(including gains from options, futures or forward contracts) derived with
respect to its business of investing in stock, securities or currencies, and (2)
diversify its holdings so that at the end of each quarter of its taxable year
(i) at least 50% of the market value of the Fund's assets is represented by cash
or cash items, U.S. government securities, securities of other regulated
investment companies, and other securities limited, in respect of any one
issuer, to an amount not greater than 5% of the value of the Fund's assets and
10% of the outstanding voting securities of such issuer, and (ii) not more than
25% of the value of its assets is invested in the securities of any one issuer
(other than U.S. government securities or the securities of other regulated
investment companies) or of two or more issuers that the Fund controls and that
are engaged in the same, similar, or related trades or businesses. These
requirements may limit the range of the Fund's investments. If a Fund qualifies
as a regulated investment company, it will not be subject to federal income tax
on the part of its income distributed to Shareholders, provided the Fund
distributes during its taxable year at least (a) 90% of its taxable net
investment income (very generally, dividends, interest, certain other income,
and the excess, if any, of net short-term capital gain over net long-term loss),
and (b) 90% of the excess of (i) its tax-exempt interest income (if any) less
(ii) certain deductions attributable to that income. Each Fund of the Trust
intends to make sufficient distributions to Shareholders to qualify for this
special tax treatment.

         If a Fund failed to qualify as a regulated investment company receiving
special tax treatment in any taxable year, the Fund would be subject to tax on
its taxable income at corporate rates, and all distributions from earnings and
profits, including any distributions of net tax-exempt income and net long-term
capital gains, would be taxable to Shareholders as ordinary income. In addition,
the Fund could be required to recognize unrealized gains, pay substantial taxes
and interest and make substantial distributions before requalifying as a
regulated investment company and being accorded special tax treatment.

         Generally, regulated investment companies that do not distribute in
each calendar year an amount equal to 98% of their "ordinary income" (as
defined) for the calendar year, plus 98% of their capital gain net income (as



                                       28
<PAGE>   140


defined) for the one-year period ending on October 31 of such calendar year,
plus any undistributed amounts from the previous year are subject to a
non-deductible excise tax equal to 4% of the undistributed amounts. For purposes
of the excise tax, a Fund is treated as having distributed any amount on which
it is subject to income tax for any taxable year ending in such calendar year.
Each Fund of the Trust intends to make sufficient distributions to avoid
liability for the excise tax.

         Shareholders of the Funds will generally be subject to federal income
tax on distributions received from the Funds. Dividends that are attributable to
a Fund's net investment income will be taxed to shareholders as ordinary income.
Distributions of net capital gain that are designated by a Fund as capital gain
dividends will generally be taxable to a Shareholder receiving such
distributions as long-term capital gain (generally taxed at a 20% tax rate for
non-corporate Shareholders) regardless of how long the Shareholder has held its
shares. Distributions in excess of a Fund's current and accumulated "earnings
and profits" will be treated by a Shareholder receiving such distributions as a
return of capital to the extent of such Shareholder's basis in its Shares in the
Fund, and thereafter as capital gain. A return of capital is not taxable, but
reduces a Shareholder's basis in its shares. Shareholders not subject to tax on
their income generally will not be required to pay tax on amounts distributed to
them. The sale, exchange or redemption of Fund shares by a Shareholder may give
rise to a taxable gain or loss to that Shareholder. In general, any gain or loss
realized upon a taxable disposition of shares will be treated as long-term
capital gain or loss if the Shareholder has held the shares for more than 12
months (generally taxed at a 20% tax rate for non-corporate shareholders), and
otherwise as short-term capital gain or loss. However, if a Shareholder sells
shares at a loss within six months of purchase, any loss will be disallowed for
Federal income tax purposes to the extent of any exempt-interest dividends
received on such shares. Dividends and distributions on a Fund's shares are
generally subject to federal income tax as described herein to the extent they
do not exceed the Fund's realized income and gains, even though such dividends
and distributions may economically represent a return of a particular
shareholder's investment. Such distributions are likely to occur in respect of
shares purchased at a time when the Fund's net asset value reflects gains that
are either unrealized, or realized but not distributed.

         In addition, any loss (not already disallowed as provided in the
preceding sentence) realized upon a taxable disposition of shares held for six
months or less will be treated as long-term to the extent of any long-term
capital gain distributions received by the Shareholder with respect to the
shares. All or a portion of any loss realized upon a taxable disposition of Fund
shares will be disallowed if other Fund shares are purchased within 30 days
before or after the disposition. In such a case, the basis of the newly
purchased shares will be adjusted to reflect the disallowed loss.

         Certain investment and hedging activities of the Funds, including
transactions in options, futures contracts, hedging transactions, forward
contracts, straddles, swaps, short sales, foreign currencies, and foreign
securities will be subject to special tax rules (including mark-to-market,
constructive sale, straddle, wash sale and short sale rules). In a given case,
these rules may accelerate income to the Fund, defer losses to the Fund, cause
adjustments in the holding periods of the Fund's securities, convert long-term
capital gains into short-term capital gains, convert short-term capital losses
into long-term capital losses, or otherwise affect the character of the Fund's
income. These rules could therefore affect the amount, timing and character of
distributions to Shareholders and cause differences between a Fund's book income
and taxable income. Income earned as a result of these transactions would, in
general, not be eligible for the dividends-received deduction or for treatment
as exempt-interest dividends when distributed to Shareholders. The Fund will
endeavor to make any available elections pertaining to such transactions in a
manner believed to be in the best interest of the Fund.

         Certain securities purchased by the Funds (such as STRIPS, CUBES, TRS,
TIGRS, and CATS), as defined in "Details About the Funds' Investment Practices
and Policies" in the Funds' Prospectuses, are sold at original issue discount
and thus do not make periodic cash interest payments. Similarly, zero-coupon
bonds do not make periodic interest payments. A Fund will be required to include
as part of its current income for tax purposes the imputed interest on such
obligations even though the Fund has not received any interest payments on such
obligations during that period. Because each Fund distributes substantially all
of its net investment income to its Shareholders (including such imputed
interest), the Fund may have to sell portfolio securities in order to generate
the cash necessary for the required distributions. Such sales may occur at a
time when Banc One Investment Advisors would not otherwise have chosen to sell
such securities and may result in a taxable gain or loss.


                                       29
<PAGE>   141


         A Fund will be required in certain cases to withhold and remit to the
United States Treasury 31% of taxable dividends or of gross proceeds from
redemptions paid to any individual Shareholder who has provided to the Fund
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
report payments of interest or dividends. This withholding, known as backup
withholding, is not an additional tax, and any amounts withheld may be credited
against the Shareholder's ultimate U.S. tax liability.

         The Internal Revenue Service recently revised its regulations affecting
the application to foreign investors of the back-up withholding and withholding
tax rules described above. The new regulations will generally be effective for
payments made after December 31, 1999 (although transition rules will apply). In
some circumstances, the new rules will increase the certification and filing
requirements imposed on foreign investors in order to qualify for exemption from
the 31% back-up withholding tax and for reduced withholding tax rates under
income tax treaties. Foreign investors in a Fund should consult their tax
advisors with respect to the potential application of these new regulations. The
foregoing is only a summary of some of the important federal tax considerations
generally affecting purchasers of Shares of a Fund of the Trust. No attempt is
made to present herein a complete explanation of the federal income tax
treatment of each Fund or its Shareholders, and this discussion is not intended
as a substitute for careful tax planning. Accordingly, prospective purchasers of
Shares of a Fund are urged to consult their tax advisors with specific reference
to their own tax situation, including the potential application of state, local
and (if applicable) foreign taxes.

         The foregoing discussion and the discussion below regarding foreign
investments are based on tax laws and regulations which are in effect on the
date of this Statement of Additional Information; such laws and regulations may
be changed by legislative, judicial or administrative action, and such changes
may be retroactive.

ADDITIONAL TAX INFORMATION CONCERNING INTERNATIONAL INVESTMENTS

         Transactions of a Fund in foreign currency denominated debt securities
(and similar instruments) may result in ordinary income or loss to the Fund for
federal income tax purposes which will be taxable to the Shareholders as such
when it is distributed to them.

         Gains from foreign currencies (including foreign currency options,
foreign currency futures and foreign currency forward contracts) will (under
regulations to be issued) constitute qualifying income for purposes of the 90%
test only to the extent that they are directly related to the trust's business
of investing in stock or securities.

         Investment by a Fund in certain "passive foreign investment companies"
could subject the Fund to a U.S. federal income tax or other charge on proceeds
from the sale of its investment in such a company or other distributions from
such a company, which tax cannot be eliminated by making distributions to
Shareholders of the Fund. If a Fund elects to treat a passive foreign investment
company as a "qualified electing fund," different rules would apply, although
the Funds do not expect to make such an election. Rather, the Funds intend to
avoid such tax or other charge by making an election to mark gains (and to a
limited extent, losses) from such investments to market annually.

         The qualified electing fund and mark-to-market elections may have the
effect of accelerating the recognition of income (without the receipt of cash)
and increase the amount required to be distributed for a Fund to avoid taxation.
Making either of these elections therefore may require a Fund to liquidate other
investments (including when it is not advantageous to do so) to meet its
distribution requirement, which also may accelerate the recognition of gain and
affect a Fund's total return.

                                   VALUATION

VALUATION OF THE MONEY MARKET FUNDS

         The Money Market Funds have elected to use the amortized cost method of
valuation pursuant to Rule 2a-7 under the 1940 Act. This involves valuing an
instrument at its cost initially and thereafter assuming a constant amortization
to maturity of any discounts or premium, regardless of the impact of fluctuating
interest rates on the market value of the instrument. This method may result in
periods during which value, as determined by amortized cost, is higher or lower
than the price each Fund would receive if it sold the instrument. The value of
securities in the Funds can be expected to vary inversely with changes in
prevailing interest rates.

         Pursuant to Rule 2a-7, the Money Market Funds will maintain a
dollar-weighted average portfolio maturity appropriate to their objective of
maintaining a stable net asset value per Share, provided that no Fund will
purchase any security with a remaining maturity of more than 397 days
(securities subject to repurchase agreements and certain variable or floating
rate instruments may bear longer maturities) nor maintain a dollar-weighted,
average portfolio maturity which exceeds 90 days. The Trust's Board of Trustees
has also undertaken to establish procedures reasonably designed, taking into
account current market conditions and a Fund's investment objective, to
stabilize the net asset value per Share of the Money Market Funds for purposes
of sales and redemptions at $1.00. These procedures include review by the
Trustees, at such intervals as they deem appropriate, to determine the extent,
if any, to which the net asset value per Share of each Fund calculated by using
available market quotations deviates from $1.00 per Share. In the event such
deviation exceeds one half of one percent, the Rule requires that the Board
promptly consider what action, if any, should be initiated. If the Trustees
believe that the extent of any deviation from a Fund's $1.00 amortized cost
price per Share may result in material dilution or other unfair results to new
or existing investors, they will take such steps as they consider appropriate to
eliminate or reduce to the extent reasonably practicable any such dilution or
unfair results. These steps may include selling portfolio instruments prior to
maturity, shortening the average portfolio maturity, withholding or reducing
dividends, reducing the number of a Fund's outstanding Shares without monetary
consideration, or utilizing a net asset value per Share determined by using
available market quotations.

VALUATION OF THE EQUITY FUNDS

         Except as noted below, investments of the Equity Funds of the Trust in
securities the principal market for which is a securities exchange are valued at
their market values based upon the latest available sales price or, absent such
a price, by reference to the latest available bid and asked prices in the
principal market in which such securities are normally traded. Except as noted
below, investments of the Funds in securities the principal market for which is
a securities exchange are valued at the closing mid-market price on that
exchange on the day of computation.

         With regard to each of the above-mentioned Funds, securities the
principal market for which is not a securities exchange are valued at the mean
of their latest bid and ask quotations in such principal market. Securities and
other assets for which quotations are not readily available are determined by
Banc One Investment Advisors to not accurately reflect their value are valued at
their fair value as determined in good faith under consistently applied
procedures established by and under the general supervision of the Trustees of
the Trust. Short-term securities are valued at either amortized cost or original
cost plus accrued interest, which approximates current value.

         The value of a foreign security is determined in its national currency
as of the close of trading on the foreign exchange or other principal market on
which it is traded, which value is then converted into its U.S. dollar
equivalent at the foreign exchange closing mid-market rate reported in the
Financial Times as the closing rate for that date. When an occurrence subsequent
to the time a value of a foreign security was so established is likely to have
changed the value, then the fair value of those securities will be determined by
consideration of other factors by or under the direction of the Trustees of the
Trust or their delegates.

         Securities for which market quotations are readily available will be
valued on the basis of quotations provided by dealers in such securities or
furnished by a pricing service. Securities for which market quotations are not
readily available and other assets will be valued at fair value using methods
determined in good faith by Banc 



                                       31

One Investment Advisors under the supervision of the Trustees and may include
yield equivalents or a pricing matrix.

                      ADDITIONAL INFORMATION REGARDING THE
                    CALCULATION OF PER SHARE NET ASSET VALUE

         The net asset value of each Fund is determined and its Class I, Class
A, Class B, Class C and Service Class Shares are priced as of the times
specified in each Fund's Prospectus. The net asset value per Share of each
Fund's Class I, Class A, Class B, Class C and Service Class Shares is calculated
by determining the value of the respective Class's proportional interest in the
securities and other assets of the Fund, less (i) such Class's proportional
share of general liabilities and (ii) the liabilities allocable only to such
Class, and dividing such amount by the number of Shares of the Class
outstanding. The net asset value of a Fund's Class I, Class A, Class B, Class C
and Service Class Shares may differ from each other due to the expense of the
Distribution and Shareholders Services Plan fee applicable to a Fund's Class A,
Class B, Class C and Service Class Shares.


                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

         All of the classes of Shares in each Fund (other than Service Class
shares) are sold on a continuous basis by The One Group Services Company (the
"DISTRIBUTOR"), and the Distributor has agreed to use appropriate efforts to
solicit all purchase orders.

         Class I Shares in a Fund may be purchased, through procedures
established by the Distributor, by institutional investors, including affiliates
of BANK ONE CORPORATION and any bank, depository institution, insurance company,
pension plan or other organization authorized to act in fiduciary, advisory,
agency, custodial or similar capacities. Class I Shares are not available to
Individual Retirement Accounts.

         Class A, Class B and Class C Shares may be purchased by any investor
that does not meet the purchase eligibility criteria, described above, with
respect to Class I Shares. In addition to purchasing Class A, Class B and Class
C Shares directly from the Distributor, an investor may purchase Class A, Class
B and Class C Shares through a financial institution, such as a bank, savings
and loan association, insurance company (each a "SHAREHOLDER SERVICING AGENT")
that has established a Shareholder servicing agreement with the Distributor, or
through a broker-dealer that has established a dealer agreement with the
Distributor. Questions concerning the eligibility requirements for each class of
the Trust's Shares may be directed to the Distributor at 1-800-480-4111.

         Service Class Shares are available only in Money Market Funds. This
class of shares is available to broker-dealers, other financial intermediaries,
banks and other depository institutions requiring special administrative and
accounting services (e.g., sweep processing).

EXCHANGES

         The exchange privileges described herein may be exercised only in those
states where the Shares of the Fund or such other Fund may be legally sold. All
exchanges discussed herein are made at the net asset value of the exchanged
Shares, except as provided below. The Trust does not impose a charge for
processing exchanges of Shares. For Federal income tax purposes, an exchange is
treated as a sale of shares and generally results in a capital gain or loss.

         Class I. Class I Shareholders of a Fund may exchange their Shares for
Class A Shares of the same Fund or for Class A Shares or Class I Shares of
another Portfolio of the Trust. Class A Shareholders may exchange their Shares
for Class I Shares of a Fund or for Class I or Class A Shares of another
Portfolio of the Trust, if the Shareholder is eligible to purchase such Shares.

         Class A Shares. If a Shareholder seeks to exchange Class A Shares of a
Fund that does not impose a sales charge for Class A Shares of a Portfolio that
does, or the Portfolio being exchanged into has a higher sales charge, 



                                       32
<PAGE>   144


the Shareholder will be required to pay a sales charge in the amount equal to
the difference between the sales charge applicable to the Fund into which the
Shares are being exchanged and any sales charge previously paid for the
exchanged Shares, including any sales charges incurred on any earlier exchanges
of the Shares (unless such sales charge is otherwise waived as provided above).
The exchange of Class I Shares for Class A Shares also will require payment of
the sales charge unless the sales charge is waived, as provided above. If a
Shareholder (no longer eligible to purchase Class I Shares) purchases Class A
Shares of a Fund, the Shareholder will be subject to Distribution and
Shareholder Services Plan Fees.

         Class B Shares. Class B Shareholders of a Fund may exchange their
Shares for Class B Shares of any other Portfolio of the Trust on the basis of
the net asset value of the exchanged Class B Shares, without the payment of any
Contingent Deferred Sales Charge that might otherwise be due upon redemption of
the outstanding Class B Shares. The newly acquired Class B Shares will be
subject to the higher Contingent Deferred Sales Charge of either the Fund from
which the Shares were exchanged or the Portfolio into which the Shares were
exchanged. With respect to outstanding Class B Shares as to which previous
exchanges have taken place, "higher Contingent Deferred Sales Charge" shall mean
the higher of the Contingent Deferred Sales Charge applicable to either the Fund
the Shares are exchanging into or any other Fund from which the Shares
previously have been exchanged. For purposes of computing the Contingent
Deferred Sales Charge that may be payable upon a disposition of the newly
acquired Class B Shares, the holding period for outstanding Class B Shares of
the Fund from which the exchange was made is "tacked" to the holding period of
the newly acquired Class B Shares. For purposes of calculating the holding
period applicable to the newly acquired Class B Shares, the newly acquired Class
B Shares shall be deemed to have been issued on the date of receipt of the
Shareholder's order to purchase the outstanding Class B Shares of the Fund from
which the initial exchange was made.

         Class C Shares. Class C Shareholders may not exchange their Class C
Shares for shares of any other class nor may shares of any other class be
exchanged for Class C Shares.

         Service Class Shares. Service Class Shareholders may not exchange their
Service Class Shares for Shares of any other class, nor may Shares of any other
class be exchanged for Service Class Shares.

REDEMPTIONS

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,

John F. Finn, are not "interested persons" of the Trust within the meaning of
that term under the 1940 Act. The Trustees, in turn, elect the officers of the
Trust to supervise actively its day-to-day operations.

         Class I shares of one or more Funds of the Trust that will be used to
         measure the performance of a Trustee's deferred compensation account. A
         Trustee's deferred compensation account will be paid at such times as
         elected by the Trustee subject to certain mandatory payment provisions
         in the Plan (e.g., death of a Trustee.)

INVESTMENT ADVISOR

         BANC ONE INVESTMENT ADVISORS CORPORATION

         Investment advisory services to each of the Trust's Portfolios are
provided by Banc One Investment Advisors. Banc One Investment Advisors makes the
investment decisions for the assets of the Funds. In addition, Banc One
Investment Advisors continuously reviews, supervises and administers the Funds'
investment program, subject to the supervision of, and policies established by,
the Trustees of the Trust. The Trust's Shares are not sponsored, endorsed or
guaranteed by, and do not constitute obligations or deposits of any bank
affiliate of Banc One Investment Advisors and are not insured by the FDIC or
issued or guaranteed by the U.S. government or any of its agencies.

         Banc One Investment Advisors is an indirect, wholly-owned subsidiary of
BANK ONE CORPORATION, a bank holding company incorporated in the state of
Delaware. BANK ONE CORPORATION has affiliate banking organizations in Arizona,
Colorado, Illinois, Indiana, Kentucky, Louisiana, Michigan, Ohio, Oklahoma,
Texas, Utah, West Virginia and Wisconsin. In addition, BANK ONE CORPORATION has
several affiliates that engage in data processing, venture capital, investment
and merchant banking, and other diversified services including trust




                                       36
<PAGE>   148


management, investment management, brokerage, equipment leasing, mortgage
banking, consumer finance, and insurance.

         Banc One Investment Advisors represents a consolidation of the
investment advisory staffs of a number of bank affiliates of BANK ONE
CORPORATION, which have considerable experience in the management of open-end
management investment company portfolios, including One Group (formerly, The One
Group and the Helmsman Fund) since 1985.

         The Funds had not commenced operations prior to the date of this
Statement of Additional Information.

         All investment advisory services are provided to the Funds by Banc One
Investment Advisors pursuant to an investment advisory agreement dated January
11, 1993 (the "INVESTMENT ADVISORY AGREEMENT"). The Investment Advisory
Agreement will continue in effect as to a particular Fund from year to year, if
such continuance is approved at least annually by the Trust's Board of Trustees
or by vote of a majority of the outstanding Shares of such Fund (as defined
under "ADDITIONAL INFORMATION--Miscellaneous" in this Statement of Additional
Information), and a majority of the Trustees who are not parties to the
respective investment advisory agreements or interested persons (as defined in
the Investment Company Act of 1940) of any party to the respective investment
advisory agreements by votes cast in person at a meeting called for such
purpose. The Investment Advisory Agreement was renewed by the Trust's Board of
Trustees at their quarterly meeting on August 20, 1998. The Investment Advisory
Agreement is terminable as to a particular 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 Fund's Advisor as the case may be. 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 Investment Advisor
shall not be liable for any error of judgment or mistake of law or for any loss
suffered by the Trust in connection with the performance of the respective
investment advisory agreements, except a loss resulting from a breach of
fiduciary duty with respect to the receipt of compensation for services or a
loss resulting from willful misfeasance, bad faith, or gross negligence on the
part of Banc One Investment Advisors in the performance of its duties, or from
reckless disregard by it of its duties and obligations thereunder.

GLASS-STEAGALL ACT

In 1971, the United States Supreme Court held in Investment Company Institute v.
Camp that the federal statute commonly referred to as the Glass-Steagall Act
prohibits a national bank from operating a Fund for the collective investment of
managing agency accounts. Subsequently, the Board of Governors of the Federal
Reserve System (the "BOARD") issued a regulation and interpretation to the
effect that the Glass-Steagall Act and such decision: (a) forbid a bank holding
company registered under the Federal Bank Holding Company Act of 1956 (the
"HOLDING COMPANY ACT") or any non-bank affiliate thereof from sponsoring,
organizing, or controlling a registered, open-end investment company
continuously engaged in the issuance of its Shares, but (b) do not prohibit such
a holding company or affiliate from acting as investment Advisor, transfer
agent, and custodian to such an investment company. In 1981, the United States
Supreme Court held in Board of Governors of the Federal Reserve System v.
Investment Company Institute that the Board did not exceed its authority under
the Holding Company Act when it adopted its regulation and interpretation
authorizing bank holding companies and their non-bank affiliates to act as
investment advisors to registered closed-end investment companies. In the Board
of Governors case, the Supreme Court also stated that if a national bank
complied with the restrictions imposed by the Board in its regulation and
interpretation authorizing bank holding companies and their non-bank affiliates
to act as investment advisors to investment companies, a national bank
performing investment advisory services for an investment company would not
violate the Glass-Steagall Act. In addition, state securities laws on this issue
may differ from the interpretations of federal law expressed herein and banks
and financial institutions may be required to register as dealers pursuant to
state law.

In the Investment Advisory Agreement with the Trust, Banc One Investment
Advisors has represented to the Trust that it possesses the legal authority to
perform the investment advisory services contemplated by the agreement and



                                       37
<PAGE>   149


described in the Prospectuses and this Statement of Additional Information
without violation of applicable statutes and regulations. Future changes in
either federal or state statutes and regulations relating to the permissible
activities of banks or bank holding companies and the subsidiaries or affiliates
of those entities, as well as further judicial or administrative decisions or
interpretations of present and future statutes and regulations, could prevent or
restrict Banc One Investment Advisors from continuing to perform such services
for the Trust. Depending upon the nature of any changes in the services which
could be provided by Banc One Investment Advisors, the Board of Trustees of the
Trust would review the Trust's relationship with Banc One Investment Advisors
and consider taking all action necessary in the circumstances.

Should future legislative, judicial, or administrative action prohibit or
restrict the proposed activities of BANK ONE CORPORATION subsidiary banks or
their correspondent banks in connection with customer purchases of Shares of the
Trust, these banks might be required to alter materially or discontinue the
services offered by them to customers. It is not anticipated, however, that any
change in the Trust's method of operations would affect its net asset value per
Share or result in financial losses to any customer.

PORTFOLIO TRANSACTIONS

Pursuant to the Investment Advisory Agreement, Banc One Investment Advisors
determines, subject to the general supervision of the Board of Trustees of the
Trust and in accordance with each Fund's investment objective and restrictions,
which securities are to be purchased and sold by each such Fund and which
brokers are to be eligible to execute its portfolio transactions. Purchases and
sales of portfolio securities with respect to the Money Market Funds usually are
principal transactions in which portfolio securities are 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 (other than certain foreign 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 Trust, where possible, will deal
directly with the dealers who make a market in the securities involved except in
those circumstances where better price and execution are available elsewhere.
While Banc One Investment Advisors generally seeks competitive spreads or
commissions, the Trust may not necessarily pay the lowest spread or commission
available on each transaction, for reasons discussed below.

Allocation of transactions, including their frequency, to various dealers is
determined by Banc One Investment Advisors with respect to the Funds it serves
based on its best judgment and in a manner deemed fair and reasonable to
Shareholders. The primary consideration is prompt execution of orders in an
effective manner at the most favorable price. Subject to this consideration,
dealers who provide supplemental investment research to Banc One Investment
Advisors may receive orders for transactions by the Trust, even if such dealers
charge commissions in excess of the lowest rates available, provided such
commissions are reasonable in light of the value of brokerage and research
services received. Such research services may include, but are not be limited
to, analysis and reports concerning economic factors and trends, industries,
specific securities, and portfolio strategies. Information so received is in
addition to and not in lieu of services required to be performed by Banc One
Investment Advisors and does not reduce the advisory fees payable to Banc One
Investment Advisors. Such information may be useful to Banc One Investment
Advisors in serving both the Trust and other clients and, conversely,
supplemental information obtained by the placement of business of other clients
may be useful to Banc One Investment Advisors in carrying out their obligations
to the Trust. In the last fiscal year, Banc One Investment Advisors directed
brokerage commissions to brokers who provided research services to Banc One
Investment Advisors. Total compensation paid to such brokers amounted to
$14,566,893.79.

The Trust will not execute portfolio transactions through, acquire portfolio
securities issued by, make savings deposits in, or enter into repurchase or
reverse repurchase agreements with its investment advisors or their affiliates
except as may be permitted under the 1940 Act, and will not give preference to
correspondents of BANK ONE CORPORATION subsidiary banks with respect to such
transactions, securities, savings deposits, repurchase agreements, and reverse
repurchase agreements.

Investment decisions for each Portfolio of the Trust are made independently from
those for the other Portfolios or any other investment company or account
managed by Banc One Investment Advisors. 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 a
given Fund and another Fund, investment company or account the transaction will
be averaged as to price, and available investments allocated as to amount, in a
manner which Banc One Investment Advisors believes to be equitable to the
Fund(s) and such other investment company or account. In some instances, this
investment procedure may adversely affect the price paid or received by a Fund
or the size of the position obtained by a Fund. To the extent permitted by law,
Banc One Investment Advisors may aggregate the securities to be sold or
purchased by it for a Fund with those to be sold or purchased by it 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 Trust, Banc One Investment Advisors will not
inquire or take into consideration whether an issuer of securities proposed for
purchase or sale by the Trust is a customer of Banc One Investment Advisors or
its parent or subsidiaries or affiliates and, in dealing with its commercial
customers, Banc One Investment Advisors and its parent, subsidiaries, and
affiliates will not inquire or take into consideration whether securities of
such customers are held by the Trust.

ADMINISTRATOR

The One Group Services Company serves as Administrator (the "ADMINISTRATOR") to
each Portfolio of the Trust pursuant to a Management and Administration
Agreement with the Trust (the "ADMINISTRATION AGREEMENT"). The Board of Trustees
of the Trust approved The One Group Services Company as the sole Administrator
for each Portfolio beginning December 1, 1995. The Administrator assists in
supervising all operations of each Portfolio to which it serves as Administrator
(other than those performed under the respective investment advisory agreements
and Custodian and Transfer Agency Agreements for that Portfolio).

Under the Administration Agreement, the Administrator has agreed to price the
portfolio securities of each Fund it serves and to compute the net asset value
and net income of such Funds on a daily basis, to maintain office facilities for
the Trust, to maintain each such Fund's financial accounts and records, and to
furnish the Trust statistical and research data, data processing, clerical,
accounting, and bookkeeping services, and certain other services required by the
Trust with respect to each such Fund. The Administrator prepares annual and
semi-annual reports to the SEC, prepares federal and State tax returns, prepares
filings with State securities commissions, and generally assists in all aspects
of the Trust's operations other than those performed under the investment
advisory agreements, and Custodian and Transfer Agency Agreements. Under the
Administration Agreement, the Administrator may delegate all or any part of its
responsibilities thereunder.

Banc One Investment Advisors also serves as Sub-Administrator to each Portfolio
of the Trust, pursuant to an agreement between the Administrator and Banc One
Investment Advisors. Pursuant to this agreement, Banc One Investment Advisors
performs many of the Administrator's duties, for which Banc One Investment
Advisors receives a fee paid by the Administrator.

The Funds had not commenced operations prior to the date of this Statement of
Additional Information.

         Unless sooner terminated, the Administration Agreement between the
Trust and The One Group Services Company will continue in effect through
November 30, 1999. The Administration Agreement thereafter shall be renewed
automatically for successive one year terms, unless written notice not to renew
is given by the non-renewing party to the other party at least sixty days prior
to the expiration of the then-current term. The Administration Agreement will be
reviewed and ratified at least annually by the Trust's Board of Trustees,
provided that the Administration Agreement is also reviewed and ratified by the
majority of the Trust's Trustees who are not parties to the Administration
Agreement or interested persons (as defined in the 1940 Act) of any party to the
Administration Agreement, by vote cast in person at a meeting called for the
purpose of reviewing and ratifying the Administration Agreement. The
Administration Agreement may be terminated with respect to a particular
Portfolio only upon mutual agreement of the parties to the Administration
Agreement and for cause (as defined in the Administration Agreement) by the
party alleging cause, on not less than sixty days' notice by the Trust's Board
of Trustees or by The One Group Services Company.


                                       39

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

DISTRIBUTOR

The One Group Services Company serves as Distributor to each Portfolio of the
Trust pursuant to its Distribution Agreement with the Trust (the "DISTRIBUTION
AGREEMENT"). The Board of Trustees of the Trust approved The One Group Services
Company as the sole Distributor beginning November 1, 1995. Unless otherwise
terminated, the Distribution Agreement will continue in effect until October 31,
1999 and will continue from year to year if approved at least annually (i) by
the Trust's Board of Trustees or by the vote of a majority of the outstanding
Shares of the Funds (see "ADDITIONAL INFORMATION-- Miscellaneous," in this
Statement of Additional Information) that are parties to the Distribution
Agreement, and (ii) by the vote of a majority of the Trustees of the Trust who
are not parties to the Distribution Agreement or interested persons of any such
party, cast in person at a meeting called for the purpose of voting on such
approval. The agreement may be terminated in the event of its assignment, as
defined in the 1940 Act. The One Group Services Company is a broker-dealer
registered with the Securities and Exchange Commission, and is a member of the
National Association of Securities Dealers, Inc.

DISTRIBUTION PLAN

The operation and fees with respect to Class A Shares, Class B Shares, Class C
Shares, and Service Class Shares of the Trust payable under the Trust's
Distribution and Shareholder Services Plans, to which Class A Shares, Class B
Shares, Class C Shares, and Service Class Shares of each Fund are subject, are
described in each such Fund's Prospectuses and in the Multiple Class Plan.

The Distribution and Shareholder Services Plan with respect to Class A Shares
(the "Distribution Plan") was initially approved on July 28, 1989 by the Trust's
Board of Trustees, including a majority of the Trustees who are not interested
persons of the Trust (as defined in the 1940 Act) and who have no direct or
indirect financial interest in the Distribution Plan (the "INDEPENDENT
TRUSTEES"). The Distribution Plan originally applied to the single class of
Shares of each Portfolio of the Trust that existed prior to the offering of the
Portfolios' Shares as five separate classes. An amendment to the Distribution
Plan was approved by the Independent Trustees on October 21, 1991, and became
effective on February 7, 1992. Such amendment limited fees under the
Distribution Plan only to the Class A Shares of each Portfolio. The Distribution
Plan was amended again on February 11, 1993 in order to make Retirement Class
Shares (now the Service Class Shares) subject to distribution fees. The
Distribution Plan was further amended on February 29, 1996, to eliminate certain
"defensive" provisions of the Distribution Plan. A Distribution and Shareholder
Services Plan (the "CDSC PLAN") for Class B and Class C Shares was initially
approved on August 12, 1993 by the Independent Trustees. The CDSC Plan was
re-executed on December 13, 1995 and amended on February 20, 1997.

The Funds had not commenced operations prior to the date of this Statement
Additional Information.

In accordance with Rule 12b-1 under the 1940 Act, the Distribution Plan and CDSC
Plan may be terminated with respect to the Class A Shares, Class B Shares, Class
C Shares or Service Class Shares of any Fund by a vote of a majority of the
Independent Trustees, or by a vote of a majority of the outstanding Class A
Shares, Class B Shares, Class C Shares or Service Class Shares, respectively, of
that Fund. The Distribution Plan and CDSC Plan may be amended by vote of the
Trust's Board of Trustees, including a majority of the Independent Trustees,
cast in person at a meeting called for such purpose, except that any change in
the Distribution Plan or Class B Distribution Plan that would materially
increase the distribution fee with respect to the Class A Shares, Class B
Shares, Class C Shares or Service Class Shares of a Fund requires the approval
of that Fund's Class A, Class B, Class C or Service Class Shareholders,
respectively. The Trust's Board of Trustees will review on a quarterly and
annual basis written reports of the amounts received and expended under the
Distribution Plan (including amounts expended by the Distributor to
Participating Organizations pursuant to the Servicing Agreements entered into
under the Distribution Plan) 



                                       40

indicating the purposes for which such expenditures were made.

CUSTODIAN AND TRANSFER AGENT

Cash and securities owned by the Funds are held by State Street Bank and Trust
Company ("STATE STREET") as Custodian. State Street serves the respective Funds
as Custodian pursuant to a Custodian Agreement with the Trust (the "CUSTODIAN
AGREEMENT"). Under the Custodian Agreement, State Street (i) maintains a
separate account or accounts in the name of each Fund; (ii) makes receipts and
disbursements of money on behalf of each Fund; (iii) collects and receives all
income and other payments and distributions on account of the Funds' portfolio
securities; (iv) responds to correspondence from security brokers and others
relating to its duties; and (v) makes periodic reports to the Trust's Board of
Trustees concerning the Trust's operations. State Street may, at its own
expense, open and maintain a sub-custody account or accounts on behalf of the
Trust, provided that State Street shall remain liable for the performance of all
of its duties under the Custodian Agreement. NBD Bank serves as Sub-Custodian
with respect to certain securities pursuant to an agreement between the Trust,
State Street and NBD Bank.

Bank One Trust Company, N.A. serves as Sub-Custodian in connection with the
Trust's securities lending activities, pursuant to agreements between the Trust,
State Street and Bank One Trust Company. Bank One Trust Company receives a fee
paid by the Trust.

Rules adopted under the 1940 Act permit the Trust to maintain its securities and
cash in the custody of certain eligible banks and securities depositories. The
Trust intends to select foreign custodians or sub-custodians to maintain foreign
securities of the Funds pursuant to such rules, following a consideration of a
number of factors, including, but not limited to, the reliability and financial
stability of the institution; the ability of the institution to perform
custodial services for the Trust; the reputation of the institution in its
national market; the political and economic stability of the country in which
the institution is located; and the risks of potential nationalization or
expropriation of Trust assets. In addition, the 1940 Act requires that foreign
bank sub-custodians, among other things have Shareholder equity in excess of
$200 million, have no lien on the Trust's assets and maintain adequate and
accessible records.

State Street serves as Transfer Agent and Dividend Disbursing Agent for each
Fund pursuant to Transfer Agency Agreements with the Trust (the "TRANSFER AGENCY
AGREEMENT"). Under the Transfer Agency Agreements, State Street has agreed (i)
to issue and redeem Shares of the Trust; (ii) to address and mail all
communications by the Trust to its Shareholders, including reports to
Shareholders, dividend and distribution notices, and proxy material for its
meetings of Shareholders; (iii) to respond to correspondence or inquiries by
Shareholders and others relating to its duties; (iv) to maintain Shareholder
accounts and certain sub-accounts; and (v) to make periodic reports to the
Trust's Board of Trustees concerning the Trust's operations.

EXPERTS

accountants. PricewaterhouseCoopers examines financial statements for the Trust
and provides other audit, tax, and related services.

The law firm of Ropes & Gray, One Franklin Square, 1301 K Street, N.W., Suite
800 East, Washington, D.C. 20005 is counsel to the Trust. From time to time,

subsidiary banks.

                             ADDITIONAL INFORMATION

DESCRIPTION OF SHARES

         The Trust is a Massachusetts Business Trust. The Trust's Declaration of
Trust was filed with the Secretary of State of the Commonwealth of Massachusetts
on May 23, 1985 and authorizes the Board of Trustees to issue an unlimited
number of Shares, which are units of beneficial interest, without par value. The
Trust's Declaration of Trust authorizes the Board of Trustees to establish one
or more series of Shares of the Trust, and to classify or 



                                       41
<PAGE>   153


reclassify any series into one or more classes by setting or changing in any one
or more respects the preferences, designations, conversion, or other rights,
restrictions, or limitations as to dividends, conditions of redemption,
qualifications, or other terms applicable to the Shares of such class, subject
to those matters expressly provided for in the Declaration of Trust, as amended,

The Portfolios of the Trust (other than the Money Market Funds listed above)
offer shares in four separate classes: Class I Shares, Class A Shares, Class B
and Class C Shares. The U.S. Treasury Securities Money Market Fund and the Prime
Money Market Fund offer Class I Shares, Class A Shares, Class B Shares, Class C
Shares, and Service Class Shares. The Government Money Market Fund and the
Treasury Only Money Market Fund offer only a single class of shares. The
Municipal Money Market Fund, the Ohio Municipal Money Market Fund, the Michigan
Municipal Money Market Fund, the U.S. Government Securities Money Market Fund
and the Treasury Prime Money Market Fund offer Class I, Class A, Class C, and
Service Class Shares. The Cash Management Funds offer Class A and Class I Shares
only. See the relevant Prospectus for those Funds for more details.

Shares have no subscription or preemptive rights and only such conversion or
exchange rights as the Board may grant in its discretion. When issued for
payment as described in the Prospectus and this Statement of Additional
Information, the Trust's Shares will be fully paid and non-assessable. In the
event of a liquidation or dissolution of the Trust, Shares of a Fund are
entitled to receive the assets available for distribution belonging to the Fund,
and a proportionate distribution, based upon the relative asset values of the
respective Funds, of any general assets not belonging to any particular Fund
which are available for distribution.

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

Class A Shares, Class B Shares, Class C Shares and Service Class Shares of a
Fund have exclusive voting rights with respect to matters pertaining to the
Fund's Distribution Plan.

SHAREHOLDER AND TRUSTEE LIABILITY

Under Massachusetts law, holders of units of beneficial interest in a business
trust may, under certain circumstances, be held personally liable as partners
for the obligations of the trust. However, the Trust's Declaration of Trust
provides that Shareholders shall not be subject to any personal liability for
the obligations of the Trust, and that every written agreement, obligation,
instrument, or undertaking made by the Trust shall contain a provision to the
effect that the Shareholders are not personally liable thereunder. The
Declaration of Trust provides for indemnification out of the trust property of
any Shareholder held personally liable solely by reason of his 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 shall satisfy any judgment thereon.
Thus, the risk of a Shareholder incurring financial loss on account of
Shareholder liability is limited to circumstances in which the Trust itself
would be unable to meet its obligations.


                                       43
<PAGE>   155


The Declaration of Trust states further that no Trustee, officer, or agent of
the Trust shall be personally liable in connection with the administration or
preservation of the assets of the trust or the conduct of the Trust's business;
nor shall any Trustee, officer, or agent 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. The Declaration of Trust
also provides that all persons having any claim against the Trustees or the
Trust shall look solely to the assets of the trust for payment.

PERFORMANCE

From time to time, the Funds may advertise yield, total return and/or
distribution rate. These figures will be based on historical earnings and are
not intended to indicate future performance. The yield of a Fund refers to the
annualized income generated by an investment in the Fund over a specified 30-day
period. The yield is calculated by assuming that the income generated by the
investment during that period is generated over a one-year period and is shown
as a percentage of the investment.

Total return is the change in value of an investment in a Fund over a given
period, assuming reinvestment of any dividends and capital gains. A cumulative
total return reflects an actual rate of return over a stated period of time. An
average annual total return is a hypothetical rate of return that, if achieved
annually, would have produced the same cumulative total return if performance
had been constant over the entire period. Average annual total returns smooth
out variations in performance; they are not the same as actual year-by-year
results.

The distribution rate is computed by dividing the total amount of the dividends
per share paid out during the past period by the maximum offering price or
month-end net asset value depending on the class of a Fund. This figure is then
"annualized" (multiplied by 365 days and divided by the applicable number of
days in the period).

Funds with a front-end sales charge would incorporate the offering price into
the distribution yield in place of month-end net asset value.

Distribution rate is a measure of the level of income paid out in cash to
Shareholders over a specified period. It differs from yield and total return and
is not intended to be a complete measure of performance. Furthermore, the
distribution rate may include return of principal and/or capital gains. Total
return is the change in value of a hypothetical investment over a given period
assuming reinvestment of dividends and capital gain distributions. The yield
refers to the cumulative 30-day rolling net investment income, divided by
maximum offering price and multiplied by average shares outstanding during this
period.

Further information about the performance of each class of the Funds is
contained in the Trust's Annual Report to Shareholders for The One Group.
Further information about the performance of the Predecessor Funds is contained
in the Pegasus Funds', Pegasus Money Market Funds and Pegasus Cash Management
Funds' Annual Report(s) to Shareholders. Copies of such reports may be obtained
without charge by calling 1-800-480-4111.

CALCULATION OF PERFORMANCE DATA

The yield for each Money Market Fund is computed with respect to each class of
Shares by determining the percentage net change, excluding capital changes, in
the value of an investment in one Share of the particular class of the Fund over
the base period, and multiplying the net change by 365/7 (or approximately 52
weeks). The effective yield of each class of each Fund represents a compounding
of the yield by adding 1 to the number representing the percentage change in
value of the investment during the base period, raising that sum to a power
equal to 365/7, and subtracting 1 from the result. No performance data is
available with respect to the Money Market Funds because they had not commenced
operations prior to the date of this Statement of Additional Information.

The performance of the Funds may be compared in publications to the performance
of various indices and investments (such as other mutual funds) for which
reliable performance data is available, as well as averages,


                                       44
<PAGE>   156

performance rankings or other information prepared by recognized mutual fund
statistical services, as set forth below.

Performance information showing a Fund's total return and/or 30-day yield with
respect to a particular class may be presented from time to time in advertising
and sales literature regarding the Equity Funds. A 30-day yield is calculated by
dividing the net investment income per-share earned during the 30-day base
period by the maximum offering price per share on the last day of the period,
according to the following formula:

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

In the above formula, "a" represents dividends and interest earned by a
particular class during the 30-day base period; "b" represents expenses accrued
to a particular class for the 30-day base period (net of reimbursements); "c"
represents the average daily number of Shares of a particular class outstanding
during the 30-day base period that were entitled to receive dividends; and "d"
represents the maximum offering price per share of a particular class on the
last day of the 30-day base period.

A Fund's respective cumulative total return and average annual total return was
determined by calculating the change in the value of a hypothetical $1,000
investment in a particular class of the Fund for each of the periods shown.
Cumulative total return for a particular class of a Fund is computed by
determining the rate of return over the applicable period that would equate the
initial amount invested to the ending redeemable value of the investment. The
cumulative return is calculated as the total dollar increase or decrease in the
value of an account assuming reinvestment of all distributions divided by the
original initial investment. The average annual return for a particular class of
a Fund is computed by determining the average annual compounded rate of return
over the applicable period that would equate the initial amount invested to the
ending redeemable value of the investment. The ending redeemable value includes
dividends and capital gain distributions reinvested at net asset value. The
resulting percentages indicated the positive or negative investment results that
an investor would have experienced from changes in share price and reinvestment
of dividends and capital gains distributions.

Performance information showing a Fund's and/or particular Class's distribution
rate may be presented from time to time in advertising and sales literature
regarding the Equity Funds. The distribution rate is calculated as follows:

distribution yield         =        a/(b) x 365
                                    -----------
_______________________________________________________c

In the formula, "a" represents dividends distributed by a particular class
during that period; "b" represents month end offer price or net asset value for
a particular class; "c" represents the number of days in the period being
calculated. "365" is the number of days in a year, used to annualize the
distribution yield.

Performance will fluctuate from time to time and is not necessarily
representative of future results. Accordingly, a Fund's performance may not
provide for comparison with bank deposits or other investments that pay a fixed
return for a stated period of time. Performance is a function of a Fund's
quality, composition, and maturity, as well as expenses allocated to the Fund.
Fees imposed upon customer accounts at a bank, with regard to Class I Shares and
Service Class Shares, or a Participating Organization, with regard to Class A
and Class B Shares, will reduce a Fund's effective yield to customers.

         In addition, the performance of each class of a Fund may from time to
time be compared to that of other mutual funds tracked by mutual fund rating
services, to that of broad groups of comparable mutual funds or to that of
unmanaged indices that may assume investment of dividends but do not reflect
deductions for administrative and management costs. Further, the performance of
each class of a Fund may be compared to other funds or to relevant indices that
may calculate total return without reflecting sales charges; in which case, a
Fund may advertise its total return in the same manner. If reflected, sales
charges would reduce these total return calculations.


                                       45
<PAGE>   157


         The Money Market Funds may quote actual total return performance in
advertising and other types of literature compared to indices or averages of
alternative financial products available to prospective investors. The
performance comparisons may include the average return of various bank
instruments, some of which may carry certain return guarantees offered by
leading banks and thrifts, as monitored by the BANK RATE MONITOR, and those of
corporate and government security price indices of various durations prepared by
Shearson Lehman Brothers, Solomon Brothers, Inc. and the IBC/Donoghue
organization. These indices are not managed for any investment goals.

         The Money Market Funds may also use comparative performance information
computed by and available from certain industry and general market research and
publications, such as Lipper Analytical Services, Inc.

         Statistical and performance information compiled and maintained by CDA
Technologies, Inc. and Interactive Data Corporation may also be used. CDA is a
performance evaluation service that maintains a statistical data base of
performance, as reported by a diverse universe of independently-managed mutual
funds. Interactive Data Corporation is a statistical access service that
maintains a data base of various industry indicators, such as historical and
current price/earning information and individual stock and fixed income price
and return information.

         Current interest rate and yield information on government debt
obligations of various durations, as reported weekly by the Federal Reserve
(Bulletin H. 15), may also be used.

         Comparative information on the Consumer Price Index may also be
included. This Index, as prepared by the U.S. Bureau of Labor Statistics, is the
most commonly used measure of inflation. It indicates the cost fluctuations of a
representative group of consumer goods. It does not represent a return on
investment.

         The Equity Funds may quote actual total return performance from time to
time in advertising and other types of literature compared to results reported
by the Dow Jones Industrial Average.

         The Dow Jones Industrial Average is an industry-accepted unmanaged
index of generally conservative securities used for measuring general market
performance. The performance reported will reflect the reinvestment of all
distributions on a quarterly basis and market price fluctuations. The index does
not take into account any brokerage commissions or other fees. Comparative
information on the Consumer Price Index may also be included.

         The Equity Funds may also promote the yield and/or total return
performance and use comparative performance information computed by and
available from certain industry and general market research and publications,
such as Lipper Analytical Services, Inc.; they may also use indices such as the
Standard & Poor's 400 Composite Stock Index, the Standard & Poor's 500 Composite
Stock Index, the Standard & Poor's 600 Composite Stock Index, the Russell 2000,
or the Morgan Stanley International European, Asian and Far East Gross Domestic
Product Index for performance comparison. Statistical and performance
information compiled and maintained by CDA Technologies, Inc. and Interactive
Data Corporation may also be used.

MISCELLANEOUS

         The Trust is not required to hold a meeting of Shareholders for the
purpose of electing Trustees except that (i) the Trust is required to hold a
Shareholders' meeting for the election of Trustees at such time as less than a
majority of the Trustees holding office have been elected by Shareholders and
(ii) if, as a result of a vacancy on the Board of Trustees, less than two-thirds
of the Trustees holding office have been elected by the Shareholders, that
vacancy may only be filled by a vote of the Shareholders. In addition, Trustees
may be removed from office by a written consent signed by the holders of Shares
representing two-thirds of the outstanding Shares of the Trust at a meeting duly
called for the purpose, which meeting shall be held upon the written request of
the holders of Shares representing not less than 20% of the outstanding Shares
of the Trust. Except as set forth above, the Trustees may continue to hold
office and may appoint successor Trustees.

         As used in the Trust's Prospectuses and in this Statement of Additional
Information, "assets belonging to a Fund" means the consideration received by
the Trust upon the issuance or sale of Shares in that Fund, together with



                                       46
<PAGE>   158


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 payments derived from any reinvestment of such
proceeds, and any general assets of the Trust not readily identified as
belonging to a particular Fund that are allocated to that Fund by the Trust's
Board of Trustees. The Board of Trustees may allocate such general assets in any
manner it deems fair and equitable. It is anticipated that the factor that will
be used by the Board of Trustees in making allocations of general assets to
particular Funds will be the relative net asset values of the respective Funds
at the time of allocation. Assets belonging to a particular Fund are charged
with the direct liabilities and expenses in respect of that Fund, and with a
share of the general liabilities and expenses of the Trust not readily
identified as belonging to a particular Fund that are allocated to that Fund in
proportion to the relative net asset values of the respective Funds at the time
of allocation. The timing of allocations of general assets and general
liabilities and expenses of the Trust to particular Funds will be determined by
the Board of Trustees of the Trust and will be in accordance with generally
accepted accounting principles. Determinations by the Board of Trustees of the
Trust as to the timing of the allocation of general liabilities and expenses and
as to the timing and allocable portion of any general assets with respect to a
particular Fund are conclusive. For information regarding the allocations of
Class Expenses to particular classes of a Fund, see the respective Prospectus of
the Fund under "MANAGEMENT-Expenses."

         As used in the Trust's Prospectuses and in this Statement of Additional
Information, a "vote of a majority of the outstanding Shares" of the Trust, a
particular Fund, or a particular class of Shares of a Fund, means the
affirmative vote of the lesser of (a) more than 50% of the outstanding Shares of
the Trust, such Fund, or such class of Shares of such Fund, or (b) 67% or more
of the Shares of the Trust, such Fund, or such class of Shares of such Fund
present at a meeting at which the holders of more than 50% of the outstanding
Shares of the Trust, such Fund, or such class of Shares of such Fund are
represented in person or by proxy.

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

                  The following portions of Registrant's Declaration of Trust
                  incorporated as Exhibit (1) hereto, define the rights of
                  shareholders:


                  5.1  Shares in the Series or Classes of the Trust.
                       ---------------------------------------------

                  A. The Trustees shall have full power and authority, in their
                  sole discretion, without obtaining the prior approval of the
                  Shareholders (either with respect to the Trust as a whole or
                  with respect to any series or classes of the Trust) by vote or
                  otherwise, to establish one or more series of Shares of the
                  Trust. The establishment of any such series shall be effective
                  upon the adoption by a majority of the Trustees then in office
                  of a resolution establishing such series and setting the
                  voting rights, preferences, designations, conversion or other
                  rights, restrictions, limitations as to distributions,
                  conditions of redemption, qualifications, or other terms of
                  the Shares of such series. The beneficial interest in each
                  series of the Trust shall at all times be divided into an
                  unlimited number of full and fractional transferable Shares
                  without par value. The investment objective, policies, and
                  restrictions governing the management and operations of each
                  series of the Trust, including the management of assets
                  belonging to any particular series, may from time to time be
                  changed or supplemented by the Trustees, subject to the
                  requirements of the Act. The Trustees may from time to time
                  divide or combine the outstanding Shares of any one or more
                  series of the Trust into a greater or lesser number without
                  thereby changing their proportionate beneficial interests in
                  the Trust assets allocated or belonging to such series.

                  Subject to the respective voting rights, preferences,
                  designations, conversion or other rights, restrictions,
                  limitations as to distributions, conditions of redemption,
                  qualifications, or other terms of the Shares of each series of
                  the Trust, the Trustees may, without Shareholder approval,
                  divide the Shares of any series into two or more classes,
                  Shares of each such class having such

                  voting rights, preferences, designations, conversion or other
                  rights, restrictions, limitations as to distributions,
                  conditions of redemption, qualifications, or other terms
                  applicable to Shares of such class as the Trustees may
                  determine.

                  B. The holder of each Share shall be entitled to one vote for
                  each full Share, and a proportionate fractional vote for each
                  fractional Share, irrespective of the series or class, then
                  recorded in his name on the books of the Trust. On any matter
                  submitted to a vote of Shareholders, all Shares then issued
                  and outstanding and entitled to vote, irrespective of the
                  series or class, shall be voted in the aggregate and not by
                  series or class except: (1) as otherwise required by the Act;
                  or (2) when the matter, as conclusively determined by the
                  Trustees, affects only the interests of the Shareholders of a
                  particular series or class of the Trust (in which case only
                  Shareholders of the affected series or class shall be entitled
                  to vote thereon).

                  C. Shares of each series or class of the Trust shall have the
                  following preferences, participating or other special rights,
                  qualifications, restrictions and limitations:

                           (1) ASSETS BELONGING TO A SERIES OR CLASS. All
                           consideration received by the Trust for the issue or
                           sale of Shares of any series or class, together with
                           all assets in which such consideration is invested or
                           reinvested, including any proceeds derived from the
                           sale, exchange, or liquidation of such assets, and
                           any funds or payments derived from any reinvestment
                           of such proceeds in whatever form the same may be,
                           shall be referred to as "assets belonging to" that
                           series or class. In addition, any assets, income,
                           earnings, profits or proceeds thereof, or funds or
                           payments which are not readily identifiable as
                           belonging to a particular series or class shall be
                           allocated by the Trustees to one or more series or
                           class (such allocation to be conclusive and binding
                           upon the Shareholders of all series or class for all
                           purposes) in such manner as they, in their sole
                           discretion, deem fair and equitable, and shall also
                           be referred to as "assets belonging to" such series
                           or class. Such assets belonging to a particular
                           series or class shall irrevocably belong for all
                           purposes to the Shares of the series or class, and
                           shall be so handled upon the books of account of the
                           Trust. Such assets and the income, earnings, profits,
                           and proceeds thereof, including any proceeds derived
                           from the sale, exchange, or liquidation thereof, and
                           any funds or payments derived from any reinvestment
                           of such proceeds in whatever form, are herein
                           referred to as "assets belonging to" such a series or
                           class. Shareholders of any series or class shall have
                           no right, title or interest in or to the assets
                           belonging to any other series or class.

                           (2) LIABILITIES BELONGING TO A SERIES OR CLASS. The
                           assets belonging to any series or class of the Trust
                           shall be charged with the direct liabilities in
                           respect of such series or class and with all
                           expenses, costs, charges, and reserves attributable
                           to such series or class, and shall also 


                                      -3-
<PAGE>   199



                           be charged with the share of such series or class of
                           the general liabilities, expenses, costs, charges,
                           and reserves of the Trust which are not readily
                           identifiable as belonging to a particular series or
                           class in proportion to the relative net assets of the
                           respective series or class, as determined at such
                           time or times as may be authorized by the Trustees.
                           Any such determination by the Trustees shall be
                           conclusive and binding upon the Shareholders of all
                           series or class for all purposes; PROVIDED, HOWEVER,
                           that under no circumstances shall the assets
                           allocated or belonging to any series or class of the
                           Trust be charged with liabilities directly
                           attributable to any other series or class. The
                           liabilities so charged to a series or class are
                           herein referred to as "liabilities belonging to" such
                           series or class. All persons who may have extended
                           credit to a particular series or class or who have
                           contracts or claims with respect to a particular
                           series or class shall look only to the assets of that
                           particular series or class for payment of such
                           contracts or claims.

                           (3) LIQUIDATING DISTRIBUTIONS. In the event of the
                           termination of the Trust or a particular series or
                           class thereof and the winding up of its affairs, the
                           Shareholders of the Trust or such particular series
                           or class shall be entitled to receive out of the
                           assets of the Trust or belonging to the particular
                           series or class, as the case may be, available for
                           distribution to Shareholders, but other than general
                           assets not belonging to any particular series or
                           class of the Trust, the assets belonging to such
                           series or class; and the assets so distributable to
                           the Shareholders of any series or class shall be
                           distributed among such Shareholders in proportion to
                           the number of Shares of such series or class held by
                           them and recorded in their names on the books of the
                           Trust. In the event that there are any general assets
                           not belonging to any particular series or class of
                           the Trust available for distribution, such
                           distribution shall be made to the Shareholders of all
                           series or class subject to such termination and
                           winding up in proportion to the relative net assets
                           of the respective series or class determined as
                           hereinafter provided and the number of Shares of such
                           series or class held by them and recorded in their
                           names on the books of the Trust.

                           (4) DIVIDENDS AND DISTRIBUTIONS. Shares of each
                           series or class shall be entitled to such dividends
                           and distributions in Shares or in cash or both, as
                           may be declared from time to time by the Trustees,
                           acting in their sole discretion, with respect to such
                           series or class, PROVIDED, HOWEVER, that dividends
                           and distributions on Shares of a particular series or
                           class shall be paid only out of the lawfully
                           available "assets belonging to" such series or class
                           as such term is defined in this Declaration of Trust.

                  5.2 PURCHASE OF SHARES. The Trustees may accept investments in
                  each series or class of the Trust from such Persons for such
                  consideration and on such 



                                      -4-
<PAGE>   200


                  other terms as they may from time to time authorize. The Trust
                  may reject any order for, or refuse to give effect on the
                  books of the Trust to the transfer of, any Shares as permitted
                  under the Act. Each such investment shall be credited to the
                  Shareholder's account in the form of full and fractional
                  Shares of the appropriate series or class of the Trust, at the
                  net asset value per Share next computed after receipt of the
                  investment.

                  5.3 NET ASSET VALUE PER SHARE. The net asset value per Share
                  of each series or class of the Trust shall be computed at such
                  time or times as the Trustees may specify pursuant to the Act.
                  Assets shall be valued and net asset value per Share shall be
                  determined by such Person or Persons as the Trustees may
                  appoint under the supervision of the Trustees in such manner
                  not inconsistent with the Act and any orders of the Securities
                  and Exchange Commission received by the Trust, as the Trustees
                  may determine.

                  5.4 OWNERSHIP OF SHARES. The ownership of Shares shall be
                  recorded separately with respect to each series or class on
                  the record books of the Trust. Certificates for Shares shall
                  be issued to holders of such Shares only upon the
                  authorization of the Trustees, in their discretion, to issue
                  such Shares, and shall be issued, if at all, subject to such
                  rules and regulations as the Trustees may determine. The
                  Trustees may make such rules as they consider appropriate for
                  the transfer of Shares and similar matters. The record books
                  of the Trust shall be conclusive as to the identity of holders
                  of Shares and as to the number of Shares of each series or
                  class held by each Shareholder.

                  5.5 PREEMPTIVE RIGHTS. Shareholders shall have no preemptive
                  or other rights to subscribe to any additional Shares or other
                  securities issued by the Trust or by the Trustees.

                  5.6 REDEMPTION OF SHARES. To the extent of the assets of the
                  Trust legally available for such redemptions, a Shareholder of
                  any series or class of the Trust shall have the right, subject
                  to the provisions of Section 5.7 hereof, to require the Trust
                  to redeem his full and fractional Shares of any series or
                  class out of assets belonging to such series or class at a
                  redemption price equal to the net asset value per Share next
                  determined after receipt of a request to redeem in proper form
                  as determined by the Trustees. The Trustees shall establish
                  such rules and procedures as they deem appropriate for
                  redemption of Shares; PROVIDED, HOWEVER, that all redemptions
                  shall be in accordance with the Act. Without limiting the
                  generality of the foregoing, the Trust shall, to the extent
                  permitted by applicable law, have the right at any time to
                  redeem the Shares owned by any holder thereof (i) if the value
                  of such Shares in an account maintained by the Trust or its
                  transfer agent for any Shareholder with respect to any series
                  or class of the Trust is $1,000 or less; PROVIDED, HOWEVER,
                  that any such Shareholder shall be notified that the value of
                  his account is $1,000 or less, and shall be allowed sixty days
                  to make additional purchases of Shares of the appropriate
                  series or class so that the value of his account will exceed
                  $1,000 before any such involuntary redemption is processed by
                  the Trust; or (ii) if the net income with respect to any
                  particular series or class of 


                                      -5-
<PAGE>   201



                  the Trust should be negative or it should otherwise be
                  appropriate to carry out the Trust's responsibilities under
                  the Act, in each case subject to such further terms and
                  conditions as the Board of Trustees of the Trust may from time
                  to time adopt. The redemption price of Shares of any series or
                  class of the Trust shall, except as otherwise provided in this
                  section, be the net asset value thereof as determined by the
                  Board of Trustees of the Trust from time to time in accordance
                  with the provisions of applicable law, less such redemption
                  fee or other charge, if any, as may be fixed by resolution of
                  the Board of Trustees of the Trust. When the net income with
                  respect to any particular series or class of the Trust is
                  negative or whenever deemed appropriate by the Board of
                  Trustees of the Trust in order to carry out the Trust's
                  responsibilities under the Act, any series or class of the
                  Trust may, without payment of compensation but in
                  consideration of the interests of the Trust or a particular
                  series or class thereof and of the Shareholders of the Trust
                  or of such series or class in maintaining a constant net asset
                  value per Share with respect to such series or class, redeem
                  pro rata from each holder of record on such day such number of
                  full and fractional Shares of such series or class as may be
                  necessary to reduce the aggregate number of outstanding Shares
                  of such series or class in order to permit the net asset value
                  thereof to remain constant. Payment of the redemption price,
                  if any, shall be made in cash by the appropriate series or
                  class of the Trust at such time and in such manner as may be
                  determined from time to time by the Board of Trustees of the
                  Trust unless, in the opinion of the Board of Trustees, which
                  shall be conclusive and binding upon the Shareholders for all
                  purposes, conditions exist which make payment wholly in cash
                  unwise or undesirable; in such event the appropriate series or
                  class of the Trust may make payment in the assets belonging or
                  allocable to such series or class, the value of which shall be
                  determined as provided herein.

                  5.7 SUSPENSION OF RIGHT OF REDEMPTION. The Trustees may
                  suspend the right of redemption by Shareholders or postpone
                  the date of payment or the recordation of transfer of Shares
                  of any series or class, as permitted under the Act or
                  applicable law. Such suspension or postponement shall take
                  effect at such time as the Trustees shall specify but not
                  later than the close of business on the business day following
                  the declaration of suspension or postponement, and thereafter
                  there shall be no right of redemption or payment or transfer
                  until the Trustees shall declare the suspension at an end. In
                  case of suspension of the right of redemption, a Shareholder
                  may either withdraw his request for redemption or receive
                  payment based on the net asset value existing after the
                  termination of the suspension.

                  5.8 CONVERSION RIGHTS. The Trustees shall have the authority
                  to provide from time to time that the holders of Shares of any
                  series or class shall have the right to convert or exchange
                  said Shares for or into Shares of one or more other series or
                  class in accordance with such requirements and procedures as
                  may be established from time to time by the Trustees.

                  8.1 VOTING POWERS. The Shareholders shall have power to vote
                  (a) for the election or removal of Trustees; (b) with respect
                  to the amendment of this Declaration of Trust as provided in
                  Section 10.8 hereof; (c) with respect to the approval of
                  investment advisory and distribution agreements entered into
                  on behalf of the Trust or one or more series or class thereof,
                  and with respect to such other matters relating to the Trust
                  as may be required by law, by this Declaration of Trust, the
                  Regulations of the Trust, by any requirements applicable to or
                  agreement of the Trust, and as the Trustees may consider
                  desirable; and (d) to the same extent as the shareholders of a
                  Massachusetts business corporation, when considering whether a
                  court action, proceeding, or claim should or should not be
                  brought or maintained derivatively or as a class action on
                  behalf of the Trust or the Shareholders; PROVIDED, HOWEVER,
                  that no Shareholder of a particular series or class shall be
                  entitled to bring, or to vote in respect of, any class or
                  derivative action not on behalf of the series or class of the
                  Trust in respect of which the Shareholder owns Shares. Every
                  Shareholder of record shall have the right to one vote for
                  every whole Share (other than Shares held in the treasury of
                  the Trust) standing in his name on the books of the Trust, and
                  to have a proportional fractional vote for any fractional
                  Share, as to any matter on which the Shareholder is entitled
                  to vote. There shall be no cumulative voting. Shares may be
                  voted in person or by proxy. On any matter submitted to a vote
                  of the Shareholders, all Shares shall be voted in the
                  aggregate and not by individual series or class, except (i)
                  where required by the Act, Shares shall be voted by individual
                  series or class, and (ii) if the Trustees shall have
                  determined that a matter affects the interests only of one or
                  more series or class, then only the Shareholders of such
                  affected series or class shall be entitled to vote thereon.
                  Until Shares are issued, the Trustees may exercise all rights
                  of Shareholders and may take any action required or permitted
                  to be taken by Shareholders by law, this Declaration of Trust,
                  or the Regulations.

                  8.2 MEETINGS. Meetings of Shareholders may be called by the
                  Trustees as provided in the Regulations, and shall be called
                  by the Trustees upon the written request of Shareholders
                  owning at least twenty percent of the outstanding Shares
                  entitled to vote.

                  8.3 QUORUM AND REQUIRED VOTE. At any meeting of the
                  Shareholders, a quorum for the transaction of business shall
                  consist of a majority of the Shares of each series or class
                  outstanding and entitled to vote with respect to a matter
                  appearing in person or by proxy; PROVIDED, HOWEVER, that at
                  any meeting at which the only actions to be taken are actions
                  required by the Act to be taken by vote of all outstanding
                  Shares of all series or class entitled to vote thereon,
                  irrespective of series or class, a quorum shall consist of a
                  majority of Shares (without regard to series or class)
                  entitled to vote thereon, and that at any meeting at which the
                  only actions to be taken shall have been determined by the
                  Board of Trustees to affect the rights and interests of one or
                  more but not all series or classes of the Trust, a quorum
                  shall consist of a majority of the outstanding Shares of the
                  series or class so affected; and PROVIDED, FURTHER, that



                                      -7-
<PAGE>   203


                  reasonable adjournments of such meeting until a quorum is
                  obtained may be made by vote of the Shares present in person
                  or by proxy. A majority of the Shares voted shall decide any
                  question and a plurality shall elect a Trustee, subject to any
                  applicable requirements of law or of this Declaration of Trust
                  or the Regulations; PROVIDED, HOWEVER, that when any provision
                  of law or of this Declaration of Trust requires the holders of
                  Shares of any particular series or class to vote by series or
                  class and not in the aggregate with respect to a matter, then
                  the vote of the majority of the outstanding Shares of that
                  series or class shall decide such matter insofar as that
                  particular series or class shall be concerned.

                  8.4 SHAREHOLDER ACTION BY WRITTEN CONSENT. Any action which
                  may be taken by Shareholders may be taken without a meeting if
                  the holders of not less than two-thirds of the Shares entitled
                  to be voted with respect to the matter consent to the action
                  in writing and the written consent is filed with the records
                  of the meetings of Shareholders. Such consent shall be treated
                  for all purposes as a vote taken at a meeting of Shareholders.

                  8.5 CODE OF REGULATIONS. The Regulations may include further
                  provisions not inconsistent with this Declaration of Trust for
                  Shareholders' meetings, votes, record dates, notices of
                  meetings, and related matters.

                  9.4 LIMITATION OF SHAREHOLDER LIABILITY. Shareholders shall
                  not be subject to any personal liability in connection with
                  the assets of the Trust for the acts or obligations of the
                  Trust. The Trustees shall have no power to bind any
                  Shareholder personally or to call upon any Shareholder for the
                  payment of any sum of money or assessment whatsoever other
                  than such as the Shareholder may at any time personally agree
                  to pay by way of subscription to any Share or otherwise. Every
                  obligation, contract, instrument, certificate, Share, other
                  security or undertaking of the Trust, and every other act
                  whatsoever executed in connection with the Trust shall be
                  conclusively presumed to have been executed or done by the
                  executors thereof only in their capacities as Trustees under
                  this Declaration of Trust or in their capacity as officers,
                  employees, or agents of the Trust, and not individually. Every
                  note, bond, contract, order, or other undertaking issued by or
                  on behalf of the Trust or the Trustees relating to the Trust
                  or to any series or class of the Trust, and the stationery
                  used by the Trust, shall include a recitation limiting the
                  obligation represented thereby to the Trust and its assets
                  (but the omission of such a recitation shall not operate to
                  bind any Shareholder), as follows:

                           "The names 'One Group(R) Mutual Funds' and 'Trustees
                           of One Group(R) Mutual Funds' refer respectively to
                           the Trust created and the Trustees, as trustees but
                           not individually or personally, acting from time to
                           time under a Declaration of Trust dated May 23, 1985
                           to which reference is hereby made and a copy of which
                           is on file at the office of the Secretary of the
                           Commonwealth of Massachusetts and elsewhere as
                           required by law, and to any and all amendments
                           thereto so filed or hereafter filed. The obligations
                           of 'One Group(R) Mutual Funds' entered

                           into in the name or on behalf thereof by any of the
                           Trustees, representatives or agents are made not
                           individually, but in such capacities, and are not
                           binding upon any of the Trustees, Shareholders or
                           representatives of the Trust personally, but bind
                           only the assets of the Trust, and all persons dealing
                           with any series of Shares of the Trust must look
                           solely to the assets of the Trust belonging to such
                           series for the enforcement of any claims against the
                           Trust."

                  The rights accruing to a Shareholder under this Section 9.4
                  shall not exclude any other right to which such Shareholder
                  may be lawfully entitled, nor shall anything herein contained
                  restrict the right of the Trust to indemnify or reimburse a
                  Shareholder in any appropriate situation even though not
                  specifically provided for herein, PROVIDED, HOWEVER, that a
                  Shareholder of any series or class of the Trust shall be
                  indemnified only from assets belonging to that series or
                  class.

                  9.5 INDEMNIFICATION OF SHAREHOLDERS. In case any Shareholder
                  or former Shareholder shall be held to be personally liable
                  solely by reason of his being or having been a Shareholder and
                  not because of his acts or omissions or for some other reason,
                  the Shareholder or former Shareholder (or his heirs,
                  executors, administrators, or other legal representatives, or,
                  in the case of a corporation or other entity, its corporate or
                  other general successor) shall be entitled out of the Trust
                  estate to be held harmless from and indemnified against all
                  loss and expense arising from such liability. The Trust shall,
                  upon request by the Shareholder, assume the defense of any
                  claim made against any Shareholder for any act or obligations
                  of the Trust, and shall satisfy any judgment thereon.

                  9.6 LIABILITIES OF A SERIES OR CLASS. Liabilities belonging to
                  any series or class of the Trust, including, without
                  limitation, expenses, fees, charges, taxes, and liabilities
                  incurred or arising in connection with a particular series or
                  class, or in connection with the management thereof, shall be
                  paid only from the assets belonging to that series or class.

                  10.3 TERMINATION OF TRUST. This Trust shall continue without
                  limitation of time; PROVIDED, HOWEVER, that:

                  A. The Trustees, with the vote of a majority of the
                  outstanding Shares of any series or class of the Trust, may
                  sell and convey the assets belonging to such series or class
                  to another trust or corporation organized under the laws of
                  any state of the United States, which is a management
                  investment company as defined in the Act, for an adequate
                  consideration which may include the assumption of all
                  outstanding obligations, taxes, and other liabilities, accrued
                  or contingent, of the series or class and which may include
                  beneficial interests of such trust or stock of such
                  corporation. Upon making provision for the payment of all such
                  liabilities, by such assumption or otherwise, the Trustees
                  shall distribute the remaining proceeds ratably among the
                  holders of the Shares of the series or class then outstanding.



                                      -9-
<PAGE>   205



                  B. The Trustees, with the vote of a majority of the
                  outstanding Shares of any series or class of the Trust, may
                  sell and convert into money all the assets belonging to such
                  series or class. Upon making provision for the payment of all
                  outstanding obligations, taxes, and other liabilities, accrued
                  or contingent, of the series or class, the Trustees shall
                  distribute the remaining assets belonging to such series or
                  class ratably among the holders of the outstanding Shares of
                  the series or class.

                  C. Without the vote of a majority of outstanding Shares of any
                  series or class of the Trust (unless Shareholder approval is
                  otherwise required by applicable law), the Trustees may
                  combine the assets belonging to any two or more series or
                  classes into a single series or class if the Trustees
                  reasonably determine that such combination will not have a
                  material adverse effect on the Shareholders of each series or
                  class affected thereby.

                  D. After the effective date of the determination of the
                  Trustees under paragraph A or B above,

                           (1) The Trust shall carry on no business relating to
                           the assets of such series or class except for the
                           purpose of winding up the affairs of such series or
                           class.

                           (2) The Trustees shall proceed to wind up the affairs
                           of such series or class and all of the powers of the
                           Trustees under this Declaration of Trust shall
                           continue until the affairs of such series or class
                           shall have been wound up, including the power to
                           fulfill or discharge the contracts of the Trust
                           relating to such series or class, to collect assets
                           of such series or class, to sell, convey, assign,
                           exchange, transfer, or otherwise dispose of all or
                           any part of the remaining assets of such series or
                           class to one or more Persons at public or private
                           sale for consideration that may consist in whole or
                           in part of cash, securities, or other property of any
                           kind, to discharge or pay its liabilities, and to do
                           all other acts appropriate to liquidate the business
                           of such series or class.

                  Upon completion of the distribution of the remaining proceeds
                  or the remaining assets as provided in paragraphs A and B of
                  this section, the Trustees may authorize the termination of
                  that series or class of the Trust. Such termination shall be
                  effective upon filing with the State Secretary of the
                  Commonwealth of Massachusetts of an instrument setting forth
                  such termination, at which time the Trustees shall be
                  discharged of any and all further liabilities and duties
                  hereunder relating to such series or class and the right,
                  title and interest of all parties shall be cancelled and
                  discharged with respect to such series or class. Such
                  instrument shall constitute an amendment to this Declaration
                  of Trust when filed with the State Secretary of the
                  Commonwealth of Massachusetts as provided in this Title X.

                  10.8  AMENDMENT PROCEDURE.

                  A. This Declaration of Trust may be amended by the affirmative
                  vote of the holders of not less than a majority of the
                  outstanding Shares of each series affected thereby (as the
                  Trustees shall determine) or by any larger vote as may be
                  required by any provisions of applicable law.

                  B. Notwithstanding any other provisions hereof, until such
                  time as a Registration Statement under the Securities Act of
                  1933, as amended, covering the first public offering of
                  securities of the Trust shall have become effective, this
                  Declaration of Trust may be terminated or amended in any
                  respect by the affirmative vote of a majority of the Trustees.

                  C. The Trustees may also amend this Declaration without the
                  vote of Shareholders to cure any error or ambiguity or to
                  change the name of the Trust or, if they deem it necessary, to
                  conform this Declaration of Trust to the requirements of
                  applicable state or federal laws or regulations or the
                  requirements of the regulated investment company provisions of
                  the Internal Revenue Code, but the Trustees shall not be
                  liable for failing to do so.

         The following portions of Registrant's Code of Regulations incorporated
         as Exhibit (2) hereto, define the rights of shareholders:

                  1.1 PLACE. An Annual Meeting of Shareholders may be held for a
                  calendar year if called by the Trustees acting in their sole
                  discretion, and any such annual or Special Meetings of

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

                  Article IX, Section 9.2 of the Registrant's Declaration of
                  Trust, incorporated as Exhibit (1) hereto, provides for the
                  indemnification of Registrant's trustees and officers.
                  Indemnification of the Registrant's principal underwriter,
                  custodians, investment advisers, administrator, and transfer
                  agents is provided for in the Registrant's respective
                  Agreements with those service providers as filed or
                  incorporated by reference as Exhibits hereto. As of the
                  effective date of this Registration Statement, the Registrant
                  has obtained from a major insurance carrier a trustees and
                  officers' liability policy covering certain types of errors
                  and omissions. In no event will Registrant indemnify any of
                  its trustees, officers, employees, or agents against any
                  liability to which such person would otherwise be subject by
                  reason of his willful misfeasance, bad faith, or gross
                  negligence in the performance of his duties, or by reason of
                  his reckless disregard of the duties involved in the conduct
                  of his office or under his agreement with Registrant.
                  Registrant will comply with Rule 484 under the Securities Act
                  of 1933 and Release 11330 under the Investment Company Act of
                  1940 in connection with any indemnification.

                  Insofar as indemnification for liability arising under the
                  Securities Act of 1933 may be permitted to trustees, officers,
                  and controlling persons of Registrant pursuant to the
                  foregoing provisions, or otherwise, Registrant has been
                  advised that in the opinion of the Securities and Exchange
                  Commission such indemnification is against public policy as
                  expressed in the Act and is, therefore, unenforceable. In the
                  event that a claim for indemnification against such
                  liabilities (other than the payment by Registrant of expenses
                  incurred or paid by a trustee, officer or controlling person
                  of Registrant in the successful defense of any action, suit or
                  proceeding) is asserted by such trustee, officer, or
                  controlling person in connection with the securities being
                  registered, Registrant will, unless in the opinion of its
                  counsel the matter has been settled by controlling precedent,
                  submit to a court of appropriate jurisdiction the question of
                  whether such indemnification by it is against public policy as
                  expressed in the Act and will be governed by the final
                  adjudication of such issue.

                             SUBCUSTODIAN AGREEMENT
                             ----------------------

         This Subcustodian Agreement (the "Agreement") is entered into as of
March , 1999 by and between State Street Bank and Trust Company, a Massachusetts
trust company (the "Custodian"), NBD Bank (the "Subcustodian") and One Group(R)
Mutual Funds, an open-end management investment company registered under the
Investment Company Act of 1940 ("One Group").

                             Background Information
                             ----------------------

A.       The Custodian has been appointed as custodian for One Group pursuant to
         a Custodian Agreement between the Custodian and One Group (the
         "Custodian Agreement").

B.       Banc One Investment Advisors Corporation, an investment advisor
         registered under the Investment Advisers Act of 1940 ( "BOIA") serves
         as investment adviser to The One Group.

C.       Prior to the merger between the Pegasus Funds and One Group, the
         Subcustodian held certain mortgage-backed securities and other assets
         (collectively, the "Securities") on behalf of the Pegasus Funds. Until
         such time as such Securities are sold on behalf of One Group or
         transferred to the Custodian, the Subcustodian is willing to continue
         to hold such Securities in an account (each, an "Account") established
         on behalf of the funds of the One Group listed on EXHIBIT A hereto.

                             STATEMENT OF AGREEMENT
                             ----------------------

         The parties hereby acknowledge the accuracy of the foregoing Background
Information and hereby agree as follows:

         Section 1. Appointment of the Subcustodian. One Group hereby instructs
the Custodian to appoint and the Custodian hereby appoints Subcustodian to hold
certain cash and the Securities. Subcustodian represents that it is qualified to
act as a custodian for a registered investment company under the Investment
Company Act of 1940, as amended. Subcustodian shall only be responsible for
custody hereunder of Securities actually delivered to it and then only while it
is held in and as a part of an Account. All securities accepted by Subcustodian
on behalf of One Group under the terms of this Agreement shall be in "street
name" or other good delivery form.

         Section 2. Registration of Securities. Securities held by the
Subcustodian (other than bearer securities) shall be registered in the name of
the Custodian or in the name of any nominee of the Custodian or in the name of
the Subcustodian or of any nominee of the Subcustodian or in the name of any
depository designated by the Subcustodian or its nominee.

         Section 3. Accounts. The Subcustodian may hold securities in: (i) the
bank vault of Subcustodian; (ii) such other banks or trust companies as have
been approved by One Group and pursuant to a written agreement between such
other banks or trust companies and the Subcustodian; (iii) its accounts with a
clearing agency registered with the Securities and Exchange Commission under
Section 17A of the Securities Exchange Act of 1934, which acts as



                                       2
<PAGE>   3


a securities depository (the "Securities Depository"); or (iv) a book-entry
account which is maintained for the Subcustodian by a Federal Reserve Bank (the
"Book Entry Account").

         So long as Subcustodian maintains any account pursuant to (iii) or (iv)
above for One Group, Subcustodian shall: (i) identify as belonging to One Group
a quantity of such securities in the fungible bulk of securities (A) registered
in the name of Subcustodian or its nominee, or (B) shown on Subcustodian's
account on the books of the Securities Depository, the Book-Entry Account, or
Subcustodian's agent; (ii) promptly send to the Custodian reports it receives
from the appropriate Federal Reserve Bank or Securities Depository on its system
of internal accounting control; and (iii) send to the Custodian such reports of
the systems of internal accounting control of Subcustodian and its agents
through which such securities are deposited as are available and as the
Custodian may reasonably request from time to time.

         Section 4. Collection of Income. Subcustodian shall collect all income
and other payments with respect to registered securities held in an Account to
which One Group shall be entitled by law or pursuant to custom in the securities
business, and shall collect all income and principal and other payments with
respect to bearer securities if, on the date of payment by the issuer, such
securities are held by Subcustodian in an Account. Subcustodian shall detach and
present for payment all coupons and other income and principal items requiring
presentation as and when they become due, shall collect dividends and interest
when due on securities held in an Account, and shall endorse and deposit for
collection, in the name of One Group, checks, drafts, and other negotiable
instruments on the same day as received.

         Subcustodian shall not be under any obligation or duty to take action
to effect collection of any amount, if the Securities on which such amount is
payable are in default and payment is refused after due demand or presentation.
Subcustodian will, however, notify BOIA in writing within a reasonable period of
time of such default and refusal to pay.

         Section 5. Instructions. Instructions furnished to the Custodian by
BOIA or to the Subcustodian by BOIA or the Custodian with respect to this
Agreement shall be signed by such officer or officers of the party giving such
instructions as are authorized from time to time by such party (each an
"Authorized Person"); provided, however, that each of the Custodian and the
Subcustodian is authorized to accept and act upon orders, whether given orally,
by telephone or otherwise, which the Custodian or the Subcustodian reasonably
believes to be given by an Authorized Person. All oral instructions shall be
promptly confirmed in writing. The records of the Subcustodian and the Custodian
shall be presumed to reflect accurately any oral instructions given by an
Authorized Person or a person believed by such party to be an Authorized Person.

         Section 6. Voting and Other Actions. Subcustodian shall promptly
deliver or mail to BOIA all forms of proxies and all notices of meetings
affecting or relating to Securities held in an Account. Upon receipt of
instructions of BOIA, Subcustodian shall execute and deliver such proxies or
other authorizations as may be required. Neither Subcustodian nor its nominee
shall vote any securities or execute any proxy to vote the same or give any
consent to take any other action with respect thereto.

         Section 7. Responsibility of Subcustodian. The Subcustodian shall use
the same care with respect to the receiving, safekeeping, handling, and
delivering of Securities, as applicable, held 



                                       3
<PAGE>   4


under this Agreement as it uses in respect of its own similar securities, but it
need not maintain any special insurance for the benefit of the Custodian, BOIA,
or One Group. The Subcustodian shall not be liable for any action taken or thing
done by it in carrying out the terms and provisions of this Agreement if done in
good faith and without negligence or willful misconduct on the Subcustodian's
part. The Custodian shall not be liable for any action taken or thing done by
(i) the Subcustodian or (ii) the Custodian in carrying out the terms and
provisions of this Agreement if done in good faith and without negligence or
willful misconduct on the Custodian's part. In providing the services hereunder,
it is understood that the Subcustodian shall neither render advice to the
Custodian, BOIA , or The One Group as to the value of securities or other
property, or make recommendations as to the advisability of investing in,
purchasing, loaning, or selling Securities or other property, nor shall the
Subcustodian, either directly or indirectly, have any discretionary authority or
control with respect to purchasing, loaning, or selling Securities or other
property for One Group.

         Subcustodian shall release and deliver securities held in a Account and
take any other action as directed by BOIA, with respect to dividends, splits,
distributions, spin-offs, puts, calls, conversions, redemptions, tenders,
exchanges, mergers, reorganizations, rights, warrants, or any other similar
activity relating to the securities. Subcustodian shall request direction of
BOIA upon receipt of actual notice where One Group has an option as to any such
activity. For purposes of this paragraph, Subcustodian shall be deemed to have
actual notice if any such activity is published in one or more of the following
publications: J.J. Kenny's Munibase System, Financial Card Service, Xcitek,
Inc., Standard & Poors' Called Bond Listing, Depository Trust Reorganization
Notices, and The Wall Street Journal. If Subcustodian does not have actual
notice of such activity, any such activity will be handled by Subcustodian on a
"best efforts" basis. The Subcustodian will follow all instructions from BOIA
with respect to voting as to any particular issue(s).

         As long as and to the extent that it exercises reasonable care,
Subcustodian shall not be responsible for the title, validity, or genuineness of
any property or evidence of title thereto received by it or delivered by it
pursuant to this Agreement and Subcustodian shall be held harmless in acting
upon instructions from an Authorized Person under this Agreement.

         Subcustodian shall be entitled to rely upon and may act upon advice of
counsel (who may or may not be counsel for the Custodian or One Group) on all
matters, and shall be without liability for any action reasonably taken or
omitted pursuant to such advice.

         If the Custodian, One Group or BOIA require Subcustodian to take any
action with respect to securities, which action involves the payment of monies
or which action may, in the opinion of Subcustodian, result in Subcustodian's or
its nominee's being liable for the payment of money or incurring liability of
some other form, BOIA or One Group, as a prerequisite to requiring Subcustodian
to take such action, shall provide indemnity to Subcustodian in an amount and
form satisfactory to Subcustodian.

         Neither Custodian nor Subcustodian shall be responsible or liable for
any failure or delay in the performance of its obligations under this Agreement
arising out of or caused directly or indirectly, by circumstances beyond its
reasonable control, including without limitation: acts of God; earthquakes;
fires; floods; wars; civil or military disturbance; sabotage; epidemics; riots;



                                       4
<PAGE>   5


terrorism; interruptions, loss or malfunctions of utilities or communications
service; accidents; labor disputes; acts of civil or military authority;
governmental action; or inability to obtain labor, material, equipment, or
transportation.

         Subcustodian shall have no duties or responsibilities whatsoever except
such duties and responsibilities as are specifically set forth in this
Agreement.

         Section 8. Fees. One Group shall in connection with each security
hereunder pay to the Subcustodian the Subcustodian's fee, which shall accrue
daily, and which shall be set forth on EXHIBIT B hereto.

         Section 9. Records and Reports. One Group hereby acknowledges that it
may have the right to receive broker confirmations within the time period
prescribed by 12 C.F.R. Section 12.5 at no additional cost. In lieu of receiving
such confirmations within such time period, One Group and Subcustodian agree to
the alternative procedures set forth in this Section. The Subcustodian shall
furnish statements of account monthly to Custodian and One Group or in such
other manner and frequency as the Subcustodian, Custodian and One Group shall
agree.

         The Sub-custodian shall provide Custodian and One Group, upon request,
with any quarterly or annual reports prepared in the normal course of business
of the Subcustodian by the Subcustodian's independent public accountants on the
accounting system, internal accounting controls and procedures for safeguarding
securities relating to the services provided by the Subcustodian under this
Agreement.

         The Subcustodian will not refuse any reasonable request for inspection
and audit of its books and records by an agent of a Fund or the Custodian, as
such records may relate to this Agreement.

         The Subcustodian shall cooperate with each Fund and the Custodian and
their respective independent public accountants in connection with annual and
other audits of the books and records of the Custodian or the Funds.

         Section 10. Effective Period, Termination and Amendment. This Agreement
shall become effective as of the date hereof and shall continue in full force
and effect until terminated as hereinafter provided, may be amended at any time
by mutual agreement of the parties hereto, and may be terminated by any party
hereto by an instrument in writing delivered or mailed, postage prepaid to the
other parties, such termination to take effect not sooner than thirty (30) days
after the date of delivery or mailing; provided, however, that the Custodian may
immediately terminate this Agreement in the event of the appointment of a
conservator or receiver for the Subcustodian by the Federal Deposit Insurance
Corporation or upon the happening of a like event at the direction of an
appropriate regulatory body or court of competent jurisdiction. Upon termination
of this Agreement, the Subcustodian shall promptly deliver all property then
held by the Subcustodian under this Agreement or cash proceeds thereof in
accordance with instructions of BOIA.

         Section 11. Communications. All communications required or permitted to
be given under this Agreement shall be in writing (including telex, telegraph or
telefax, facsimile, or similar electronic transmittal device) unless expressly
provided otherwise, and addressed as follows:

rules, regulations, and public policies to the extent possible. If and to the
extent that any court of competent jurisdiction determines it is impossible to

compliance with any term of this Agreement, to exercise any option, enforce any

                  computer and other equipment to perform the services

4.       INDEMNIFICATION.

         4.01.    Each party (an "Indemnitor") shall indemnify and hold harmless
                  the other party, each of such other party's affiliated
                  companies, and all of the divisions, subsidiaries, directors,
                  officers, agents, employees and assigns of each of the
                  foregoing (collectively, "Indemnified Parties"), against and
                  from any and all demands, damages, liabilities, and losses, or
                  any pending or completed actions, claims, suits, complaints,
                  proceedings, or investigations (including all expenses of
                  litigation or arbitration, judgments, fines or amounts paid in
                  any settlement consented to by the Indenmitor) to which any of
                  them may be or become subject as a result or arising out of
                  (a) any negligent act or omission by the Indemnitor or its
                  agents relating to the performance of its obligations under
                  this Agreement; (b) any breach of the Indemnitor's
                  representations or warranties contained in this Agreement; (c)
                  the Indemnitor's failure to comply with any of the terms of
                  this Agreement; or (d) the acceptance by any Indemnified Party
                  of any transaction or account maintenance information from the
                  Indemnitor with respect to the Plans or their assets. Each
                  party represents and warrants that at all times it has
                  sufficient financial resources, whether through a fidelity
                  bond or otherwise, to meet all of its indemnification
                  obligations arising under this Agreement.

         4.02.    In order that the indemnification provisions contained herein
                  shall apply, upon the assertion of a claim or loss for which
                  either party may be required to indemnify the other, the party
                  seeking indemnification shall promptly notify the other party
                  of such assertion or loss, and shall keep the other advised
                  with respect to all developments concerning such claim. The
                  party who may be required to indemnify shall have the option
                  to participate at its expense with the party seeking
                  indemnification in the defense of such claim. The party
                  seeking indemnification shall in no case confess any claim or
                  make any compromise in any case in which the other party may
                  be required to indemnify it except with the other party's
                  prior written consent. The obligations of the parties hereto

         5.       ACKNOWLEDGMENTS. Plan Agent acknowledges that each Fund, as a
                  registered investment company under the 1940 Act, is subject
                  to the provisions of the 1940 Act and regulations thereunder,
                  and that the offer and sale of its shares are subject to the
                  provisions of federal and state laws and regulations
                  applicable to the offer and sale of securities. The Fund
                  Company and TOGSC acknowledges that Plan Agent is not
                  responsible for such Fund's compliance with such laws and
                  regulations.

         6.       STATEMENTS REGARDING THE FUNDS. It is understood by the
                  parties that the Plan Agent's representatives will discuss
                  with Participants the investment objectives and policies of
                  the Funds: provided, however, that Plan Agent is not
                  authorized to make any representations concerning the
                  Distributor, any Fund, or a Fund's Shares except those
                  representations contained in the Fund's then-current
                  Prospectus and the Company's Statement of Additional
                  Information and in such printed information as the Distributor
                  or the Company may subsequently prepare.
                  [;solely as set forth in the Fund's current Prospectus and
                  other written materials prepared by the Fund Company or its
                  affiliates, and the recent investment performance of the Funds
                  as provided by the Fund Company, TOGSC or a third party
                  distributor of performance data.]

         7.       REVIEW OF PARTICIPANT COMMUNICATIONS MATERIALS. It is
                  understood by the parties that, based on the Fund's current
                  Prospectus and the information supplied by the Fund Company or
                  its designee under Section 1.12. above, the Plan Agent may
                  prepare communications or disclosure materials for the Plans
                  and their Participants which describe the Funds. Except for
                  those materials described above, the Plan Agent shall supply
                  the Fund, or its designated representative, with copies of all
                  other materials concerning the Funds within a reasonable time
                  period in advance of their intended distribution to the Plans
                  or their Participants. The Plan Agent and the Fund Company
                  shall establish a mutually agreeable time frame in which such
                  materials shall be reviewed and approved for use by the Fund
                  Company , or its designated representative. The Plan Agent
                  agrees not to use any such materials without the prior

                  prospectuses and sales literature. The Fund Company represents
                  and warrants that such sales literature has been filed with
                  the NASD and reflects resolution of any NASD comments thereon.
                  Plan Agent agrees its use of such materials in literature
                  prepared by Plan Agent will conform to applicable law and NASD
                  Conduct Rules, including any filing requirements with respect
                  to such literature.

         8.       OTHER FUND INFORMATION. The Fund Company agrees to supply the
                  Plan Agent with any information which it may have that could
                  have an adverse impact on the performance of the Funds in the
                  same manner and time frame in which such information is made
                  available to the Fund's shareholders.

         9.       REASONABLE ACCESS. The Fund Company will provide Plan Agent or
                  its designated affiliate with reasonable access to its
                  offices, representatives, sales support personnel and Fund

for the Fund (the "Transfer Agent") to establish a master account for each
investment portfolio of the Fund identified on Schedule A (individually, a
"Portfolio"; collectively, the "Portfolios") on its mutual fund shareholder
accounting system reflecting the aggregate ownership of such Portfolios by each
of the tax-qualified defined contribution plans made available by First Chicago
NBD Bank (individually, a "Plan"; collectively, the "Plans") for which BQPS has
agreed to provide Plan recordkeeping services;

         WHEREAS, it is intended that BQPS will establish individual accounts on
its defined contribution plan record-keeping system reflecting all transactions
by or on behalf of participants and beneficiaries under the Plans which result
in purchases or redemptions by the Plans of shares of the Portfolios;

         WHEREAS, it is intended that BFS will act as a servicing agent for the
Fund to receive orders by the Plans for purchases and redemptions of shares of
the Portfolios resulting from transactions by or on behalf of the Plan
participants and beneficiaries which are recorded on BQPS' defined contribution
plan record-keeping system;

         WHEREAS, the parties hereto have agreed to utilize the Fund/SERV system
established by National Securities Clearing Corporation ("NSCC") for the
placement and settlement of Fund trades ("Fund/SERV"); and

         WHEREAS, it is intended that the settlement of trades through Fund/SERV
will provide for the settlement of trades within three days of each trade date.

         NOW, THEREFORE, in consideration of the mutual covenants contained

         behalf of any Plan participant in any Portfolio in accordance with the
         terms and conditions of the applicable Plan and the Fund's
         prospectuses;

                  (b) any authorized direction to transfer or exchange existing,
         amounts held on behalf of any participant or beneficiary by the
         applicable Plan to any Portfolio in accordance with the terms and
         conditions of the Plan and the Fund's prospectuses;

                  (c) any authorized direction to transfer or exchange existing,

         offered under the Plan in accordance with the terms and conditions of
         the Plan and the Fund's prospectuses; and

                  (d) any authorized direction to pay loan, withdrawal or

all transactions by each Plan involving shares of the Portfolios (including
purchases, redemptions and reinvestments of dividends and capital gains
distributions),with the corresponding participant-level transactions on BQPS'
defined contribution plan record-keeping system.

         advise Transfer Agent as to, the foregoing. To the extent required
         under the 1940 Act and rules thereunder, NBD agrees that such records

         THIS AGENCY AGREEMENT made as of the lst day of November, 1996, by and
between Pegasus Funds (the "Trust"), a registered investment company under the
Investment Company Act of 1940 (the "l940 Act"), and Putnam Fiduciary Trust
Company, a Massachusetts trust company with its principal office at One Post
Office Square, Boston, Massachusetts ("PFTC").

         WHEREAS, PFTC has agreed to provide certain administrative and
recordkeeping services as agent for certain employee benefit plans, profit
sharing plans and retirement plans identified in Schedule A, as amended from
time to time (the "Plans") for certain portfolios of the Trust (the "Funds"),
and is a transfer agent registered under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"); and

         NOW, THEREFORE, in consideration of the promises and mutual covenants
herein contained, the parties hereto agree as follows:

         Section 1. Appointment of PFTC. The Trust hereby appoints PFTC as an
agent for the Trust for the sole purpose of accepting orders for the purchase,
and requests for redemption ("Instructions"), of the authorized and issued
shares of beneficial interest or common stock of the Funds (the "Shares")
purchased, held or redeemed by a Plan. PFTC accepts such appointment and agrees
to render the services herein set forth for the compensation herein provided.

         Section 2. Duties of the Parties.

                  2.01 PFTC shall perform the following services:

         Shares by the close of regular trading on the New York Stock Exchange
         (the "Close of Trading") each business day that the New York Stock
         Exchange is open for business ("Business Day"), transmit such orders to
         the Transfer Agent for acceptance on such Business Day and promptly
         deliver or instruct the Plans (or the Plans' Trustee(s) as the case may
         be) to deliver payment and appropriate documentation therefor to
         Transfer Agent for acceptance;

                           (b) Receive from the Plans by the close of Trading
         each Business Day redemption requests and redemption directions,
         transmit such requests and directions to the Transfer Agent and deliver
         appropriate documentation therefor to Transfer Agent, in each case for
         acceptance on such Business Day; and

                           (c) As instructed, maintain adequate records related
         to, and advise Transfer Agent as to, the foregoing. To the extent
         required under the 1940 Act and rules thereunder, PFTC agrees that such

information as may reasonably be requested (including, without limitation,
periodic certifications confirming the provision of the services described

Parties"), against any losses, claims, damages, liabilities or expenses
(including any legal or other expenses reasonably incurred by them in connection

                                FEES AND-EXPENSES


         The fees referred to in Section 3 of this Agreement shall be as
follows:

I.       For those Plans listed in Part I of Schedule A, Putnam shall receive a
base fee as follows:

         a.       $1 per transaction, which includes a payroll contribution to a
         mutual fund in a participant account, enrollments and telephone calls
         to live operators. Exchanges or transfers are not transactions for
         purposes of this calculation; and

         b.       $3 per participant mutual fund account per annum; and

         c.       An annual charge of 0.18% (18 basis points) on the Trust's 
         equity, balanced and asset allocation funds, 0.19% (19 basis points) on
         the Trust's fixed income funds and 0.20% (20 basis points) on the
         Trust's money market funds based on the average daily net assets
         invested by the Plans.

II.      Such fees shall be fixed for a period of three years. However, in the
event that Putnam changes its standard sub-transfer agent pricing and such a
change would reduce the sub-transfer agent fees paid by the Trust's mutual
funds, then the Trust will receive the benefits of such a change.

II.      Such fees shall be fixed for a period of three years. However, in the
event that Putnam changes its standard sub-transfer agent pricing and such a
change would reduce the sub- transfer agent fees paid by the Trust's mutual
funds, then the Trust will receive the benefits of such a change.

fees will cease as of the effective date of (i) the termination of TOGSC's
Distribution Agreement with the Fund or (ii) the termination of the plan, as the
case may be. This paragraph does not relieve the Trust or TOGSC of the
obligation for payment of past fees due under this Agreement. In the event such
payment obligation shall cease in accordance with clause (i) above, Company may
seek to receive such payments from any successor distributor that is appointed
by the Funds. In the event such payment obligation shall cease in accordance
with clause (ii) above, the Trust and Company agree to negotiate in good faith
with respect to whether and to what extent the Trust will continue to make such
payments either from 



                                       63

         The Fund Company shall not be liable to the Recordkeeper for any loss
         or damage, including counsel fees and court costs, whether or not
         resulting from its acts or omissions to act hereunder or otherwise
         hereunder, unless the loss or damage arises out of the Fund Company's
         own bad faith, willful misfeasance, negligence or from its reckless
         disregard of its obligations and duties.

10.      Termination. The Fund Company will provide the Recordkeeper with ninety
         (90) days prior written notice if purchase Orders may no longer be

One Group(R) Mutual Funds
3435 Stelzer Road
Columbus, Ohio  43219

Ladies and Gentlemen:

         You have registered under the Securities Act of 1933, as amended (the
"1933 Act") an indefinite number of shares of beneficial interest ("Shares") of
The One Group(R) ("Trust"), as permitted by Rule 24f-2 under the Investment
Company Act of 1940, as amended (the "1940 Act"). You propose to file a
post-effective amendment on Form N-1A (the "Post-Effective Amendment") to your
Registration Statement in order to register under the 1933 Act and the 1940 Act
shares of the Funds of the Trust.

         We have examined your Agreement and Declaration of Trust on file in the
office of the Secretary of The Commonwealth of Massachusetts and the Clerk of
the City of Boston. We have also examined a copy of your Code of Regulations and
such other documents, receipts and records as we have deemed necessary for the
purpose of this opinion.

         Based on the foregoing, we are of the opinion that the issue and sale
of authorized but unissued Shares of the Funds have been duly authorized under
Massachusetts law. Upon the original issue and sale of your authorized but
unissued Shares and upon receipt of the authorized consideration therefor in an
amount not less than the net asset value of the Shares established and in force
at the time of their sale, the Shares issued will be validly issued, fully paid
and non-assessable.

         The Trust is an entity of the type commonly known as a "Massachusetts
business trust." Under Massachusetts law, shareholders could, under certain
circumstances, be held personally liable for the obligations of the Trust.
However, the Agreement and Declaration of Trust provides for indemnification out
of the property of a particular series of Shares for all loss and expenses of
any shareholder of that series held personally liable solely by reason of his
being or having been a shareholder. Thus, the risk of shareholder liability is
limited to circumstances in which that series of Shares itself would be unable
to meet its obligations.

         We understand that this opinion is to be used in connection with the
filing of the Post-Effective Amendment. We consent to the filing of this opinion
with and as part of your Post-Effective Amendment.


                                   Sincerely,

                                   /s/ Ropes & Gray
